{Delta}9-Tetrahydrocannabinol Alleviates Hyperalgesia in a Humanized Mouse Model of Sickle Cell Disease [Special Section: Cannabinoid Signaling in Human Health and Disease]

People with sickle cell disease (SCD) often experience chronic pain as well as unpredictable episodes of acute pain, which significantly affects their quality of life and life expectancy. Current treatment strategies for SCD-associated pain primarily rely on opioid analgesics, which have limited efficacy and cause serious adverse effects. Cannabis has emerged as a potential alternative, yet its efficacy remains uncertain. In this study, we investigated the antinociceptive effects of 9-tetrahydrocannabinol (THC), cannabis’ intoxicating constituent, in male HbSS mice, which express >99% human sickle hemoglobin, and male HbAA mice, which express normal human hemoglobin A, as a control. Acute THC administration (0.1–3 mg/kg–1, i.p.) dose-dependently reduced mechanical and cold hypersensitivity in human sickle hemoglobin (HbSS) but not human normal hemoglobin A (HbAA) mice. In the tail-flick assay, THC (1 and 3 mg/kg–1, i.p.) produced substantial antinociceptive effects in HbSS mice. By contrast, THC (1 mg/kg–1, i.p.) did not alter anxiety-like behavior (elevated plus maze) or long-term memory (24-hour novel object recognition). Subchronic THC treatment (1 and 3 mg/kg–1, i.p.) provided sustained relief of mechanical hypersensitivity but led to tolerance in cold hypersensitivity in HbSS mice. Together, the findings identify THC as a possible therapeutic option for the management of chronic pain in SCD. Further research is warranted to elucidate its mechanism of action and possible interaction with other cannabis constituents.

SIGNIFICANCE STATEMENT

The study explores 9-tetrahydrocannabinol (THC)’s efficacy in alleviating pain in sickle cell disease (SCD) using a humanized mouse model. Findings indicate that acute THC administration reduces mechanical and cold hypersensitivity in SCD mice without impacting emotional and cognitive dysfunction. Subchronic THC treatment offers sustained relief of mechanical hypersensitivity but leads to cold hypersensitivity tolerance. These results offer insights into THC's potential as an alternative pain management option in SCD, highlighting both its benefits and limitations.

Analgesic Properties of Next-Generation Modulators of Endocannabinoid Signaling: Leveraging Modern Tools for the Development of Novel Therapeutics [Special Section: Cannabinoid Signaling in Human Health and Disease-Minireview]

Targeting the endocannabinoid (eCB) signaling system for pain relief is an important treatment option that is only now beginning to be mechanistically explored. In this review, we focus on two recently appreciated cannabinoid-based targeting strategies, treatments with cannabidiol (CBD) and α/β-hydrolase domain containing 6 (ABHD6) inhibitors, which have the exciting potential to produce pain relief through distinct mechanisms of action and without intoxication. We review evidence on plant-derived cannabinoids for pain, with an emphasis on CBD and its multiple molecular targets expressed in pain pathways. We also discuss the function of eCB signaling in regulating pain responses and the therapeutic promises of inhibitors targeting ABHD6, a 2-arachidonoylglycerol (2-AG)-hydrolyzing enzyme. Finally, we discuss how the novel cannabinoid biosensor GRABeCB2.0 may be leveraged to enable the discovery of targets modulated by cannabinoids at a circuit-specific level.

SIGNIFICANCE STATEMENT

Cannabis has been used by humans as an effective medicine for millennia, including for pain management. Recent evidence emphasizes the therapeutic potential of compounds that modulate endocannabinoid signaling. Specifically, cannabidiol and inhibitors of the enzyme ABHD6 represent promising strategies to achieve pain relief by modulating endocannabinoid signaling in pain pathways via distinct, nonintoxicating mechanisms of action.

The National Center for Complementary and Integrative Health: Priorities for Cannabis and Cannabinoid Research [Special Section: Cannabinoid Signaling in Human Health and Disease-Commentary]

The National Center for Complementary and Integrative Health (NCCIH), which is part of the US National Institutes of Health (NIH), has a broad interest in studying the biologic activities of natural products, especially those for which compelling evidence from preclinical research suggests biologic activities that may be beneficial to health or have a potential role in disease treatment, as well as products used extensively by the American public. As of 2023, use of cannabis for medical purposes is legal in 38 states and Washington, D.C. Such use continues to climb generally without sufficient knowledge regarding risks and benefits. In keeping with NCCIH’s natural product research priorities and recognizing this gap in knowledge, NCCIH formally launched a research program in 2019 to expand research on the possible benefits for pain management of certain substances found in cannabis: minor cannabinoids and terpenes. This Viewpoint provides additional details and the rationale for this research priority at NCCIH. In addition, NCCIH’s efforts and initiatives to facilitate and coordinate an NIH research agenda focused on cannabis and cannabinoid research are described.

SIGNIFICANCE STATEMENT

Use of cannabis for purported medical purposes continues to increase despite insufficient knowledge regarding risks and benefits. Research is needed to help health professionals and patients make knowledgeable decisions about using cannabis and cannabinoids for medical purposes. The National Center for Complementary and Integrative Health, along with other NIH Institutes, Centers, and Offices, is expanding study on the safety, efficacy, and harms of cannabis—a complex mixture of phytochemicals that needs to be studied alone and in combination.

Cannabis and Cannabinoid Signaling: Research Gaps and Opportunities [Special Section: Cannabinoid Signaling in Human Health and Disease-Commentary]

Cannabis and its products have been used for centuries for both medicinal and recreational purposes. The recent widespread legalization of cannabis has vastly expanded its use in the United States across all demographics except for adolescents. Meanwhile, decades of research have advanced our knowledge of cannabis pharmacology and particularly of the endocannabinoid system with which the components of cannabis interact. This research has revealed multiple targets and approaches for manipulating the system for therapeutic use and to ameliorate cannabis toxicity or cannabis use disorder. Research has also led to new questions that underscore the potential risks of its widespread use, particularly the enduring consequences of exposure during critical windows of brain development or for consumption of large daily doses of cannabis with high content 9-tetrahydrocannabinol. This article highlights current neuroscience research on cannabis that has shed light on therapeutic opportunities and potential adverse consequences of misuse and points to gaps in knowledge that can guide future research.

SIGNIFICANCE STATEMENT

Cannabis use has escalated with its increased availability. Here, the authors highlight the challenges of cannabis research and the gaps in our knowledge of cannabis pharmacology and of the endocannabinoid system that it targets. Future research that addresses these gaps is needed so that the endocannabinoid system can be leveraged for safe and effective use.

MIRD Pamphlet No. 30: MIRDfit--A Tool for Fitting of Biodistribution Time-Activity Data for Internal Dosimetry

In nuclear medicine, estimating the number of radioactive decays that occur in a source organ per unit administered activity of a radiopharmaceutical (i.e., the time-integrated activity coefficient [TIAC]) is an essential task within the internal dosimetry workflow. TIAC estimation is commonly derived by least-squares fitting of various exponential models to organ time–activity data (radiopharmaceutical biodistribution). Rarely, however, are methods used to objectively determine the model that best characterizes the data. Additionally, the uncertainty associated with the resultant TIAC is generally not evaluated. As part of the MIRDsoft initiative, MIRDfit has been developed to offer a biodistribution fitting software solution that provides the following essential features and advantages for internal dose assessment: nuclear medicine–appropriate fit functions; objective metrics for guiding best-fit selection; TIAC uncertainty calculation; quality control and data archiving; integration with MIRDcalc software for dose calculation; and a user-friendly Excel-based interface. For demonstration and comparative validation of MIRDfit’s performance, TIACs were derived from serial imaging studies involving 18F-FDG and 177Lu-DOTATATE using MIRDfit. These TIACs were then compared with TIAC estimates obtained using other software. In most cases, the TIACs agreed within approximately 10% between MIRDfit and the other software. MIRDfit has been endorsed by the MIRD Committee of the Society of Nuclear Medicine and Molecular Imaging and has been integrated into the MIRDsoft suite of free dosimetry software; it is available for download at no user cost (https://mirdsoft.org/).

Correlation of FAPI PET Uptake with Immunohistochemistry in Explanted Lungs from Patients with Advanced Interstitial Lung Disease

Recent studies have demonstrated promising results of fibroblast activation protein (FAP) inhibitor (FAPI) PET in prognosticating and monitoring interstitial lung diseases (ILDs). As a first step toward successful translation, our primary aim was to validate the FAPI PET uptake through immunohistochemistry in patients with advanced ILD who underwent lung transplantation after a FAPI PET scan. Methods: This is a preliminary analysis of a single-center, open-label, single-arm, prospective exploratory biodistribution study of 68Ga-FAPI-46 PET imaging in patients with ILD (NCT05365802). Patients with ILD confirmed by high-resolution CT and scheduled for lung transplant were included. Tissue samples of explanted lungs were obtained from both the central and peripheral lung parenchyma of each lobe. Additional samples were obtained from areas of the lung corresponding to regions of FAPI PET activity. Immunohistochemical staining was performed with an anti-FAP antibody. Percentages of FAP immunohistochemistry-positive area were measured semiautomatically using QuPath software. SUVs in the areas of pathologic samples were measured on FAPI PET/CT by referencing the gross photomap of the explanted lung. A Spearman correlation coefficient test was used to assess the relationship between FAPI PET uptake and FAP immunohistochemical expression in each specimen. Results: Four patients with advanced ILD who underwent FAPI PET/CT before lung transplantation were included. The types of ILD were idiopathic pulmonary fibrosis (n = 2), rheumatoid arthritis–associated ILD (n = 1), and nonspecific interstitial pneumonia (n = 1). FAPI uptake was visualized mainly in the fibrotic area on CT. Twenty-nine surgical pathology samples from 3 patients were analyzed. FAP staining was predominantly positive in fibroblastic foci. FAPI PET SUVmax and SUVmean showed a positive correlation with the immunohistochemical FAP expression score (SUVmax: r = 0.57, P = 0.001; SUVmean: r = 0.54, P = 0.002). Conclusion: In this analysis conducted in patients who underwent lung transplantation after a FAPI PET scan, FAPI PET uptake was positively correlated with FAP immunohistochemistry. These findings provide a rationale for further investigation of FAPI PET as a potential imaging biomarker for ILD.

Validation of a Simplified Tissue-to-Reference Ratio Measurement Using SUVR to Assess Synaptic Density Alterations in Alzheimer Disease with [11C]UCB-J PET

Simplified methods of acquisition and quantification would facilitate the use of synaptic density imaging in multicenter and longitudinal studies of Alzheimer disease (AD). We validated a simplified tissue-to-reference ratio method using SUV ratios (SUVRs) for estimating synaptic density with [11C]UCB-J PET. Methods: Participants included 31 older adults with AD and 16 with normal cognition. The distribution volume ratio (DVR) using simplified reference tissue model 2 was compared with SUVR at short scan windows using a whole-cerebellum reference region. Results: Synaptic density was reduced in AD participants using DVR or SUVR. SUVR using later scan windows (60–90 or 70–90 min) was minimally biased, with the strongest correlation with DVR. Effect sizes using SUVR at these late time windows were minimally reduced compared with effect sizes with DVR. Conclusion: A simplified tissue-to-reference method may be useful for multicenter and longitudinal studies seeking to measure synaptic density in AD.

Somatostatin: Linking Cognition and Alzheimer Disease to Therapeutic Targeting [Review Article]

Over 4 decades of research support the link between Alzheimer disease (AD) and somatostatin [somatotropin-releasing inhibitory factor (SRIF)]. SRIF and SRIF-expressing neurons play an essential role in brain function, modulating hippocampal activity and memory formation. Loss of SRIF and SRIF-expressing neurons in the brain rests at the center of a series of interdependent pathological events driven by amyloid-β peptide (Aβ), culminating in cognitive decline and dementia. The connection between the SRIF and AD further extends to the neuropsychiatric symptoms, seizure activity, and inflammation, whereas preclinical AD investigations show SRIF or SRIF receptor agonist administration capable of enhancing cognition. SRIF receptor subtype-4 activation in particular presents unique attributes, with the potential to mitigate learning and memory decline, reduce comorbid symptoms, and enhance enzymatic degradation of Aβ in the brain. Here, we review the links between SRIF and AD along with the therapeutic implications.

Significance Statement

Somatostatin and somatostatin-expressing neurons in the brain are extensively involved in cognition. Loss of somatostatin and somatostatin-expressing neurons in Alzheimer disease rests at the center of a series of interdependent pathological events contributing to cognitive decline and dementia. Targeting somatostatin-mediated processes has significant therapeutic potential for the treatment of Alzheimer disease.

Posttranslational Modifications of {alpha}-Synuclein, Their Therapeutic Potential, and Crosstalk in Health and Neurodegenerative Diseases [Review Article]

α-Synuclein (α-Syn) aggregation in Lewy bodies and Lewy neurites has emerged as a key pathogenetic feature in Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. Various factors, including posttranslational modifications (PTMs), can influence the propensity of α-Syn to misfold and aggregate. PTMs are biochemical modifications of a protein that occur during or after translation and are typically mediated by enzymes. PTMs modulate several characteristics of proteins including their structure, activity, localization, and stability. α-Syn undergoes various posttranslational modifications, including phosphorylation, ubiquitination, SUMOylation, acetylation, glycation, O-GlcNAcylation, nitration, oxidation, polyamination, arginylation, and truncation. Different PTMs of a protein can physically interact with one another or work together to influence a particular physiological or pathological feature in a process known as PTMs crosstalk. The development of detection techniques for the cooccurrence of PTMs in recent years has uncovered previously unappreciated mechanisms of their crosstalk. This has led to the emergence of evidence supporting an association between α-Syn PTMs crosstalk and synucleinopathies. In this review, we provide a comprehensive evaluation of α-Syn PTMs, their impact on misfolding and pathogenicity, the pharmacological means of targeting them, and their potential as biomarkers of disease. We also highlight the importance of the crosstalk between these PTMs in α-Syn function and aggregation. Insight into these PTMS and the complexities of their crosstalk can improve our understanding of the pathogenesis of synucleinopathies and identify novel targets of therapeutic potential.

Significance Statement

α-Synuclein is a key pathogenic protein in Parkinson’s disease and other synucleinopathies, making it a leading therapeutic target for disease modification. Multiple posttranslational modifications occur at various sites in α-Synuclein and alter its biophysical and pathological properties, some interacting with one another to add to the complexity of the pathogenicity of this protein. This review details these modifications, their implications in disease, and potential therapeutic opportunities.

Bile Acid Signaling in Metabolic and Inflammatory Diseases and Drug Development [Review Article]

Bile acids are the end products of cholesterol catabolism. Hepatic bile acid synthesis accounts for a major fraction of daily cholesterol turnover in humans. Biliary secretion of bile acids generates bile flow and facilitates biliary secretion of lipids, endogenous metabolites, and xenobiotics. In intestine, bile acids facilitate the digestion and absorption of dietary lipids and fat-soluble vitamins. Through activation of nuclear receptors and G protein-coupled receptors and interaction with gut microbiome, bile acids critically regulate host metabolism and innate and adaptive immunity and are involved in the pathogenesis of cholestasis, metabolic dysfunction-associated steatotic liver disease, alcohol-associated liver disease, type-2 diabetes, and inflammatory bowel diseases. Bile acids and their derivatives have been developed as potential therapeutic agents for treating chronic metabolic and inflammatory liver diseases and gastrointestinal disorders.

Significance Statement

Bile acids facilitate biliary cholesterol solubilization and dietary lipid absorption, regulate host metabolism and immunity, and modulate gut microbiome. Targeting bile acid metabolism and signaling holds promise for treating metabolic and inflammatory diseases.

Low-Field (64 mT) Portable MRI for Rapid Point-of-Care Diagnosis of Dissemination in Space in Patients Presenting with Optic Neuritis [CLINICAL PRACTICE]

BACKGROUND AND PURPOSE:

Low-field 64 mT portable brain MRI has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of portable MRI (pMRI) in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom onset to MRI.

MATERIALS AND METHODS:

Newly diagnosed patients with optic neuritis referred to a tertiary academic MS center from July 2022 to January 2024 underwent both point-of-care pMRI and subsequent 3T conventional MRI (cMRI). Images were evaluated for periventricular (PV), juxtacortical (JC), and infratentorial (IT) lesions. DIS was determined on brain MRI per 2017 McDonald criteria. Test characteristics were computed by using cMRI as the reference. Interrater and intermodality agreement between pMRI and cMRI were evaluated by using the Cohen . Time from symptom onset to pMRI and cMRI during the study period was compared with the preceding 1.5 years before pMRI implementation by using Kruskal-Wallis with post hoc Dunn tests.

RESULTS:

Twenty patients (median age: 32.5 years [interquartile range {IQR}, 28–40]; 80% women) were included, of whom 9 (45%) and 5 (25%) had DIS on cMRI and pMRI, respectively. Median time interval between pMRI and cMRI was 7 days (IQR, 3.5–12.5). Interrater agreement was very good for PV (95%, = 0.89), and good for JC and IT lesions (90%, = 0.69 for both). Intermodality agreement was good for PV (90%, = 0.80) and JC (85%, = 0.63), and moderate for IT lesions (75%, = 0.42) and DIS (80%, = 0.58). pMRI had a sensitivity of 56% and specificity of 100% for DIS. The median time from symptom onset to pMRI was significantly shorter (8.5 days [IQR 7–12]) compared with the interval to cMRI before pMRI deployment (21 days [IQR 8–49], n = 50) and after pMRI deployment (15 days [IQR 12–29], n = 30) (both P < .01). Time from symptom onset to cMRI in those periods was not significantly different (P = .29).

CONCLUSIONS:

In patients with optic neuritis, pMRI exhibited moderate concordance, moderate sensitivity, and high specificity for DIS compared with cMRI. Its integration into the MS clinic reduced the time from symptom onset to MRI. Further studies are warranted to evaluate the role of pMRI in expediting early MS diagnosis and as an imaging tool in resource-limited settings.

Enzyme Replacement Therapy for CLN2 Disease: MRI Volumetry Shows Significantly Slower Volume Loss Compared with a Natural History Cohort [CLINICAL PRACTICE]

BACKGROUND AND PURPOSE:

Neuronal ceroid lipofuscinoses are a group of neurodegenerative disorders. Recently, enzyme replacement therapy (ERT) was approved for neuronal ceroid lipofuscinosis type 2 (CLN2), a subtype of neuronal ceroid lipofuscinoses. The aim of this study was to quantify brain volume loss in CLN2 disease in patients on ERT in comparison with a natural history cohort using MRI.

MATERIALS AND METHODS:

Nineteen (14 female, 5 male) patients with CLN2 disease at 1 UK center were studied using serial 3D T1-weighted MRI (follow-up time, 1–9 years). Brain segmentation was performed using FreeSurfer. Volume measurements for supratentorial gray and white matter, deep gray matter (basal ganglia/thalami), the lateral ventricles, and cerebellar gray and white matter were recorded. The volume change with time was analyzed using a linear mixed-effects model excluding scans before treatment onset. Comparison was made with a published natural history cohort of 12 patients (8 female, 4 male), which was re-analyzed using the same method.

RESULTS:

Brain volume loss of all segmented brain regions was much slower in treated patients compared with the natural history cohort. For example, supratentorial gray matter volume in treated patients decreased by a mean of 3% (SD, 0.74%) (P < .001) annually compared with an annual volume loss of a mean of 16.8% (SD, 1.5%) (P < .001) in the natural history cohort.

CONCLUSIONS:

Our treatment cohort showed a significantly slower rate of brain parenchymal volume loss compared with a natural history cohort in several anatomic regions. Our results complement prior clinical data that found a positive response to ERT. We demonstrate that automated MRI volumetry is a sensitive tool to monitor treatment response in children with CLN2 disease.

Neuroimaging Correlates with Clinical Severity in Wilson Disease: A Multiparametric Quantitative Brain MRI [RESEARCH]

BACKGROUND AND PURPOSE:

Previous studies have reported metal accumulation and microstructure changes in deep gray nuclei (DGN) in Wilson disease (WD). However, there are limited studies that investigate whether there is metal accumulation and microstructure changes in DGN of patients with WD with normal-appearing routine MRI. This study aimed to evaluate multiparametric changes in DGN of WD and whether the findings correlate with clinical severity in patients with WD.

MATERIALS AND METHODS:

The study enrolled 28 patients with WD (19 with neurologic symptoms) and 25 controls. Fractional anisotropy (FA), mean diffusivity (MD), and magnetic susceptibility in globus pallidus, pontine tegmentum, dentate nucleus, red nucleus, head of caudate nucleus, putamen, substantia nigra, and thalamus were extracted. Correlations between imaging data and the Unified Wilson’s Disease Rating Scale (UWDRS) neurologic subitems were explored.

RESULTS:

FA, MD, and susceptibility values were higher in multiple DGN of patients with WD than controls (P < .05). Patients with WD without abnormal signals in DGN on routine MRI also had higher FA, MD, and susceptibility values than controls (P < .017). We found that UWDRS neurologic subscores correlated with FA and susceptibility values of DGN (P < .05). In addition, we also found that FA and susceptibility values in specific structures correlated with specific neurologic symptoms of WD (ie, tremor, parkinsonism, dysarthria, dystonia, and ataxia) (P < .05).

CONCLUSIONS:

Patients with WD have increased FA, MD, and susceptibility values even before the lesion is morphologically apparent on routine MRI. The increased FA and susceptibility values correlate with clinical severity of WD.

Prognosis of Proximal and Distal Vertebrobasilar Artery Stent Placement [CLINICAL PRACTICE]

BACKGROUND AND PURPOSE:

Vertebrobasilar artery stent placement (VBS) is potentially effective in preventing recurrent posterior circulation strokes; however, the incidences of in-stent restenosis and stented-territory ischemic events based on the location of stent placement have rarely been investigated. We aimed to investigate the characteristics and prognosis of VBS between intracranial and extracranial.

MATERIALS AND METHODS:

This study was single-center retrospective cohort study, and we obtained medical records of patients who underwent VBS. We compared clinical and periprocedural factors between extracranial and intracranial VBS. The primary outcomes included the incidence of in-stent restenosis (>50% reduction in lumen diameter) and stented-territory ischemic events. We compared the incidence of in-stent restenosis and stented-territory ischemic events by using Kaplan-Meier curves.

RESULTS:

Of the 105 patients, 41 (39.0%) underwent extracranial VBS, and 64 (61.0%) underwent intracranial VBS. During the follow-up, the incidences of in-stent restenosis and stented-territory ischemic events were 15.2% and 22.9%, respectively. The procedure time was longer (47.7 ± 19.5 minutes versus 74.5 ± 35.2 minutes, P < .001), and the rate of residual stenosis (≥30%) just after VBS was higher (2 [4.9%] versus 24 [37.5%], P < .001) in intracranial VBS than in extracranial VBS. Also, the incidences of in-stent restenosis were significantly higher in intracranial VBS than in extracranial VBS (4.9% versus 21.9%, P = .037). On the other hand, the incidences of stented-territory ischemic events (7.3% versus 32.8%, P < .001) were significantly higher in intracranial VBS than in extracranial VBS. The main mechanisms of stroke were artery-to-artery embolism (2 [66.7%]) in extracranial VBS, and artery-to-artery embolism (9 [42.9%]) and branch atheromatous disease (8 [38.1%]) in intracranial VBS. The Kaplan-Meier curve demonstrated a higher incidence of in-stent restenosis and stented-territory ischemic events in intracranial VBS than in extracranial VBS (P = .008 and P = .002, respectively).

CONCLUSIONS:

During the follow-up, the incidence of in-stent restenosis and stented-territory ischemic events was higher in patients with intracranial VBS than in those with extracranial VBS. The higher rates of postprocedural residual stenosis might have contributed to the increased risk of in-stent restenosis. Furthermore, prolonged procedure time and additional stroke mechanism, including branch atheromatous disease, might be associated with a higher risk of stented-territory ischemic events in intracranial VBS.

Clinical and Pathophysiologic Correlates of Basilar Artery Measurements in Fabry Disease [CLINICAL PRACTICE]

BACKGROUND AND PURPOSE:

Alterations of the basilar artery (BA) anatomy have been suggested as a possible MRA feature of Fabry disease (FD). Nonetheless, no information about their clinical or pathophysiologic correlates is available, limiting our comprehension of the real impact of vessel remodeling in FD.

MATERIALS AND METHODS:

Brain MRIs of 53 subjects with FD (mean age, 40.7 [SD, 12.4] years; male/female ratio = 23:30) were collected in this single-center study. Mean BA diameter and its tortuosity index were calculated on MRA. Possible correlations between these metrics and clinical, laboratory, and advanced imaging variables of the posterior circulation were tested. In a subgroup of 20 subjects, a 2-year clinical and imaging follow-up was available, and possible longitudinal changes of these metrics and their ability to predict clinical scores were also probed.

RESULTS:

No significant association was found between MRA metrics and any clinical, laboratory, or advanced imaging variable (P values ranging from –0.006 to 0.32). At the follow-up examination, no changes were observed with time for the mean BA diameter (P = .84) and the tortuosity index (P = .70). Finally, baseline MRA variables failed to predict the clinical status of patients with FD at follow-up (P = .42 and 0.66, respectively).

CONCLUSIONS:

Alterations of the BA in FD lack of any meaningful association with clinical, laboratory, or advanced imaging findings collected in this study. Furthermore, this lack of correlation seems constant across time, suggesting stability over time. Taken together, these results suggest that the role of BA dolichoectasia in FD should be reconsidered.

Distribution and Disparities of Industry Payments to Neuroradiologists [CLINICAL PRACTICE]

BACKGROUND AND PURPOSE:

Physician-industry relationships can be useful for driving innovation and technologic progress, though little is known about the scale or impact of industry involvement in neuroradiology. The purpose of this study was to assess the trends and distributions of industry payments to neuroradiologists.

MATERIALS AND METHODS:

Neuroradiologists were identified using a previously-validated method based on Work Relative Value Units and Neiman Imaging Types of Service classification. Data on payments from industry were obtained from the Open Payments database from the Centers for Medicare & Medicaid Services, from 2016 to 2021. Payments were grouped into 7 categories, including consulting fees, education, gifts, medical supplies, research, royalties/ownership, and speaker fees. Descriptive statistics were calculated.

RESULTS:

A total of 3019 neuroradiologists were identified in this study. Between 2016 and 2021, 48% (1440/3019) received at least 1 payment from industry, amounting to a total number of 21,967 payments. Each year, among those receiving payments from industry, each unique neuroradiologist received between a mean of 5.49–7.42 payments and a median of 2 payments, indicating a strong rightward skew to the distribution of payments. Gifts were the most frequent payment type made (60%, 13,285/21,967) but accounted for only 4.1% ($689,859/$17,010,546) of payment value. The greatest aggregate payment value came from speaker fees, which made up 36% ($6,127,484/$17,010,546) of the total payment value. The top 5% highest paid neuroradiologists received 42% (9133/21,967) of payments, which accounted for 84% ($14,284,120/$17,010,546) of the total dollar value. Since the start of the coronavirus 2019 (COVID-19) pandemic, the number of neuroradiologists receiving industry payments decreased from a mean of 671 neuroradiologists per year prepandemic (2016–2019) to 411 in the postpandemic (2020–2021) era (P = .030). The total number of payments to neuroradiologists decreased from 4177 per year prepandemic versus 2631 per year postpandemic (P = .011).

CONCLUSIONS:

Industry payments to neuroradiologists are highly concentrated among top earners, particularly among the top 5% of payment recipients. The number of payments decreased during the COVID-19 pandemic, though the dollar value of payments was offset by coincidental increases in royalty payments. Further investigation is needed in subsequent years to determine if the postpandemic changes in industry payment trends continue.

Common clonal origin of three distinct hematopoietic neoplasms in a single patient: B-cell lymphoma, T-cell lymphoma, and polycythemia vera [RESEARCH ARTICLE]

The potential for more than one distinct hematolymphoid neoplasm to arise from a common mutated stem or precursor cell has been proposed based on findings in primary human malignancies. Particularly, angioimmunoblastic T-cell lymphoma (AITL), which shares a somatic mutation profile in common with other hematopoietic malignancies, has been reported to occur alongside myeloid neoplasms or clonal B-cell proliferations, with identical mutations occurring in more than one cell lineage. Here we report such a case of an elderly woman who was diagnosed over a period of 8 years with diffuse large B-cell lymphoma, polycythemia vera, and AITL, each harboring identical somatic mutations in multiple genes. Overall, at least five identical nucleotide mutations were shared across multiple specimens, with two identical mutations co-occurring at variable variant allele frequencies in all three specimen types. These findings lend credence to the theory that a common mutated stem cell could give rise to multiple neoplasms through parallel hematopoietic differentiation pathways.

Novel pathogenic PDX1 gene variant in a Korean family with maturity-onset diabetes of the young [VARIANT DISCREPANCY RESOLUTION]

The diagnosis of maturity-onset diabetes of the young (MODY), a monogenic form of diabetes mellitus caused by a mutation in a single gene, is often uncertain until genetic testing is performed. We report a 13-yr-old Korean boy who was initially diagnosed with type 2 diabetes (T2DM). MODY was suspected because of his nonobese body habitus and family history of multiple affected members. Targeted panel sequencing of all MODY-related genes was performed using the NextSeq 550Dx platform (Illumina). Sanger sequencing was performed using blood samples from the parents, siblings, and other relatives. A frameshift variant in the 3' region of the last exon of PDX1 was detected in the patient and his family members with diabetes. PP1_Moderate criterion was applied and this variant was confirmed to be the genetic cause of diabetes in the family and classified as likely pathogenic. The study highlights the importance of genetic testing for nonobese, early-onset diabetic patients with multiple affected family members. Increased awareness and aggressive genetic testing for MODY are needed.

Reclassification of the HPGD p.Ala13Glu variant causing primary hypertrophic osteoarthropathy [VARIANT DISCREPANCY RESOLUTION]

Here, we highlight the case of a 31-yr-old man who had clinical features of primary hypertrophic osteoarthropathy (PHOAR) and harbored a homozygous variant (c.38C > A, p.Ala13Glu) in the HPGD gene, as indicated by whole-exome sequencing (WES). This variant has been previously classified by our laboratory as a variant of uncertain significance (VUS). However, another patient with the same phenotype and the same homozygous variant in HPGD was subsequently reported. In reassessing the variant, the absence of this variant in the gnomAD population database, supporting computational predictions, observation in homozygosity in two probands, and specificity of the phenotype for HPGD, all provide sufficient evidence to reclassify the HPGD c.38C > A, p.Ala13Glu variant as likely pathogenic.

Selection of Affibody Molecules Using Staphylococcal Display

Affibody molecules are small (6-kDa) affinity proteins generated by directed evolution for specific binding to various target molecules. The first step in this workflow involves the generation of an affibody library, which can then be used for biopanning using multiple display methods. This protocol describes selection from affibody libraries using display on Staphylococcus carnosus. Display of affibodies on staphylococci is very efficient and straightforward because of the single cell membrane and the use of a construct with a constitutive promoter. The workflow involves display of affibody libraries on the surface of S. carnosus cells, followed by screening and selection of binders using fluorescence-activated cell sorting (FACS). The transformation of DNA libraries into S. carnosus is less efficient and more complicated than for Escherichia coli. Because of this, staphylococcal display is suitable for affinity maturation or other protein-engineering efforts that are not dependent on very high diversity, and thus magnetic-activated cell sorting (MACS) is often not required before FACS. However, MACS is an option, and MACS procedures used for E. coli can easily be adapted for use in S. carnosus if needed.

Selection of Affibody Molecules Using Escherichia coli Display

Affibody molecules are small (6-kDa) affinity proteins generated by directed evolution for specific binding to various target molecules. The first step in this workflow involves the generation of an affibody library, which can then be used for selection via multiple display methods. This protocol describes selection from affibody libraries by Escherichia coli cell surface display. With this method, high-diversity libraries of 1011 can be displayed on the cell surface. The method involves two steps for selection of binders from high-diversity libraries: magnetic-activated cell sorting (MACS) and fluorescence-activated cell sorting (FACS). MACS is used first to enrich the library in target-binding clones and to decrease diversity to a size that can be effectively screened and sorted in the flow cytometer in a reasonable time (typically <107 cells). The protocol is based on methodology using an AIDA-I autotransporter for display on the outer membrane, but the general procedures can also be adjusted and used for other types of autotransporters or alternative E. coli display methods.




dis

Selection of Affibody Molecules Using Phage Display

Affibody molecules are small (6-kDa) affinity proteins generated by directed evolution for specific binding to various target molecules. The first step in this workflow involves the generation of an affibody library. This is then followed by amplification of the library, which can then be used for biopanning using multiple methods. This protocol describes amplification of affibody libraries, followed by biopanning using phage display and analysis of the selection output. The general procedure is mainly for selection of first-generation affibody molecules from large naive (unbiased) libraries, typically yielding affibody hits with affinities in the low nanomolar range. For selection from affinity maturation libraries with the aim of isolating variants of even higher affinities, the procedure is similar, but parameters such as target concentration and washing are adjusted to achieve the proper stringency.




dis

Cloning of Affibody Libraries for Display Methods

Affibody molecules are small (6-kDa) affinity proteins folded in a three-helical bundle and generated by directed evolution for specific binding to various target molecules. The most advanced affibody molecules are currently tested in the clinic, and data from more than 300 subjects show excellent activity and safety profiles. The generation of affibody molecules against a particular target starts with the generation of an affibody library, which can then be used for panning using multiple methods and selection systems. This protocol describes the molecular cloning of DNA-encoded affibody libraries to a display vector of choice, for either phage, Escherichia coli, or Staphylococcus carnosus display. The DNA library can come from different sources, such as error-prone polymerase chain reaction (PCR), molecular shuffling of mutations from previous selections, or, more commonly, from DNA synthesis using various methods. Restriction enzyme-based subcloning is the most common strategy for affibody libraries of higher diversity (e.g., >107 variants) and is described here.

GPs&#x2019; views of prescribing beta- blockers for people with anxiety disorders: a qualitative study

BackgroundBetween 2003 and 2018, incident prescriptions of beta-blockers for anxiety increased substantially, particularly for young adults. National Institute for Health and Care Excellence guidance for anxiety does not recommend beta-blockers, probably due to a lack of evidence to support such use. Recent reports have highlighted the potential risks of beta-blockers.AimTo understand when and why GPs prescribe beta-blockers for people with anxiety.Design and settingIn-depth interviews with 17 GPs in Bristol and the surrounding areas.MethodInterviews were held by telephone or video call. A topic guide was used to ensure consistency across interviews. Interviews were audio-recorded, transcribed verbatim, and analysed thematically.ResultsMany GPs viewed beta-blockers as ‘low risk’, particularly for young adults. Some GPs viewed beta-blockers as an alternative to benzodiazepines, acting quickly and not leading to dependence. GPs reflected that some patients appeared to want an ‘immediate fix’ to their symptoms, which GPs thought beta-blockers could potentially offer. This is salient in light of substantial waiting lists for talking therapies and delays in antidepressants taking effect. GPs described how some patients seemed more willing to try beta-blockers than antidepressants, as patients did not perceive them as ‘mental health drugs’ and therefore viewed them as potentially more acceptable and less stigmatising. Further, GPs viewed beta-blockers as ‘patient-led’, with patients managing their own dose and frequency, without GP input.ConclusionMany GPs believe that beta-blockers have a role to play in the management of anxiety. Given recent increases in the prescribing of these drugs in primary care, there is a need to assess their safety and effectiveness as a treatment for people with anxiety disorders.

Collaborative discussions between GPs and pharmacists to optimise patient medication: a qualitative study within a UK primary care clinical trial

BackgroundThere has been significant investment in pharmacists working in UK general practice to improve the effective and safe use of medicines. However, evidence of how to optimise collaboration between GPs and pharmacists in the context of polypharmacy (multiple medication) is lacking.AimTo explore GP and pharmacist views and experiences of in-person, interprofessional collaborative discussions (IPCDs) as part of a complex intervention to optimise medication use for patients with polypharmacy in general practice.Design and settingA mixed-method process evaluation embedded within the Improving Medicines use in People with Polypharmacy in Primary Care (IMPPP) trial conducted in Bristol and the West Midlands, between February 2021 and September 2023.MethodAudio-recordings of IPCDs between GPs and pharmacists, along with individual semi-structured interviews to explore their reflections on these discussions, were used. All recordings were transcribed verbatim and analysed thematically.ResultsA total of 14 practices took part in the process evaluation from February 2022 to September 2023; 17 IPCD meetings were audio-recorded, discussing 30 patients (range 1–6 patients per meeting). In all, six GPs and 13 pharmacists were interviewed. The IPCD was highly valued by GPs and pharmacists who described benefits, including: strengthening their working relationship; gaining in confidence to manage more complex patients; and learning from each other. It was often challenging, however, to find time for the IPCDs.ConclusionThe model of IPCD used in this study provided protected time for GPs and pharmacists to work together to deliver whole-patient care, with both professions finding this beneficial. Protected time for interprofessional liaison and collaboration, and structured interventions may facilitate improved patient care.

The Odyssey of HOMER: Comparative Effectiveness Research on Medication for Opioid Use Disorder During the COVID-19 Pandemic [Special Report]

The usual challenges of conducting primary care research, including randomized trials, have been exacerbated, and new ones identified, during the COVID-19 pandemic. HOMER (Home versus Office for Medication Enhanced Recovery; subsequently, Comparing Home, Office, and Telehealth Induction for Medication Enhanced Recovery) is a pragmatic, comparative-effectiveness research trial that aims to answer a key question from patients and clinicians: What is the best setting in which to start treatment with buprenorphine for opioid use disorder for this patient at this time? In this article, we describe the difficult journey to find the answer. The HOMER study began as a randomized trial comparing treatment outcomes in patients starting treatment with buprenorphine via induction at home (unobserved) vs in the office (observed, synchronous). The study aimed to enroll 1,000 participants from 100 diverse primary care practices associated with the State Networks of Colorado Ambulatory Practices and Partners and the American Academy of Family Physicians National Research Network. The research team faced unexpected challenges related to the COVID-19 pandemic and dramatic changes in the opioid epidemic. These challenges required changes to the study design, protocol, recruitment intensity, and funding conversations, as well as patience. As this is a participatory research study, we sought, documented, and responded to practice and patient requests for adaptations. Changes included adding a third study arm using telehealth induction (observed via telephone or video, synchronous) and switching to a comprehensive cohort design to answer meaningful patient-centered research questions. Using a narrative approach based on the Greek myth of Homer, we describe here the challenges and adaptations that have provided the opportunity for HOMER to thrive and find the way home. These clinical trial strategies may apply to other studies faced with similar cultural and extreme circumstances.

Family Medicine Resident Scholarly Activity Infrastructure, Output, and Dissemination: A CERA Survey [Original Research]

PURPOSE

Meeting scholarly activity requirements continues to be a challenge in many family medicine (FM) residency programs. Studies comprehensively describing FM resident scholarship have been limited. We sought to identify institutional factors associated with increased scholarly output and meeting requirements of the Accreditation Council for Graduate Medical Education (ACGME).

OBJECTIVES

Our goals were to: (1) describe scholarly activity experiences among FM residents compared with ACGME requirements; (2) classify experiences by Boyer’s domains of scholarship; and (3) associate experiences with residency program characteristics and scholarly activity infrastructure.

METHODS

This was a cross-sectional survey. The survey questions were part of an omnibus survey to FM residency program directors conducted by the Council of Academic Family Medicine Educational Research Alliance (CERA). All ACGME-accredited US FM residency program directors, identified by the Association of Family Medicine Residency Directors, were sampled.

RESULTS

Of the 691 eligible program directors, 298 (43%) completed the survey. The respondents reported that 25% or more residents exceeded ACGME minimum output, 17% reported that 25% or more residents published their work, and 50% reported that 25% or more residents delivered conference presentations. Programs exceeding ACGME scholarship requirements exhibit robust infrastructure characterized by access to faculty mentorship, scholarly activity curricula, Institutional Review Board, medical librarian, and statistician.

CONCLUSIONS

These findings suggest the need for codified ACGME requirements for scholarly activity infrastructure to ensure access to resources in FM residency programs. By fostering FM resident engagement in scholarly activity, programs help to create a culture of inquiry, and address discrepancies in funding and output among FM residency programs.

[PERSPECTIVES] {alpha}-Synuclein in Parkinson's Disease: 12 Years Later

α-Synuclein (AS) is a small presynaptic protein that is genetically, biochemically, and neuropathologically linked to Parkinson's disease (PD) and related synucleinopathies. We present here a review of the topic of this relationship, focusing on more recent knowledge. In particular, we review the genetic evidence linking AS to familial and sporadic PD, including a number of recently identified point mutations in the SNCA gene. We briefly go over the relevant neuropathological findings, stressing the evidence indicating a correlation between aberrant AS deposition and nervous system dysfunction. We analyze the structural characteristics of the protein, in relation to both its physiologic and pathological conformations, with particular emphasis on posttranslational modifications, aggregation properties, and secreted forms. We review the interrelationship of AS with various cellular compartments and functions, with particular focus on the synapse and protein degradation systems. We finally go over the recent exciting data indicating that AS can provide the basis for novel robust biomarkers in the field of synucleinopathies, while at the same time results from the first clinical trials specifically targeting AS are being reported.

Management of opioid use disorder: 2024 update to the national clinical practice guideline [Guideline]

Background

In an evolving landscape of practices and policies, reviewing and incorporating the latest scientific evidence is necessary to ensure optimal clinical management for people with opioid use disorder. We provide a synopsis of the 2024 update of the 2018 National Guideline for the Clinical Management of Opioid Use Disorder, from the Canadian Research Initiative in Substance Matters.

Methods

For this update, we followed the United States Institute of Medicine’s Standards for Developing Trustworthy Clinical Practice Guidelines and used the Appraisal of Guidelines Research and Evaluation—Recommendation Excellence tool to ensure guideline quality. We carried out a comprehensive systematic literature review, capturing the relevant literature from Jan. 1, 2017, to Sept. 14, 2023. We drafted and graded recommendations according to the Grading of Recommendations, Assessments, Development and Evaluation approach. A multidisciplinary external national committee, which included people with living or lived experience of opioid use disorder, provided input that was incorporated into the guideline.

Recommendations

From the initial 11 recommendations in the 2018 guideline, 3 remained unchanged, and 8 were updated. Specifically, 4 recommendations were consolidated into a single revised recommendation; 1 recommendation was split into 2; another recommendation was moved to become a special consideration; and 2 recommendations were revised. Key changes have arisen from substantial evidence supporting that methadone and buprenorphine are similarly effective, particularly in reducing opioid use and adverse events, and both are now considered preferred first-line treatment options. Slow-release oral morphine is recommended as a second-line option. Psychosocial interventions can be offered as adjunctive treatment but should not be mandatory. The guideline reaffirms the importance of avoiding withdrawal management as a standalone intervention and of incorporating evidence-based harm reduction services along the continuum of care.

Interpretation

This guideline update presents new recommendations based on the latest literature for standardized management of opioid use disorder. The aim is to establish a robust foundation upon which provincial and territorial bodies can develop guidance for optimal care.

At least 231 people were killed and hundreds more wounded after a massive truck bomb on Saturday struck Somalia’s capital city of Mogadishu.

The Somali government has blamed the al-Qaida-linked militant group al-Shabab for the attack, and called it the deadliest ever to hit the nation.

The blast took place outside the Safari Hotel, where rescue workers dug through the rubble of collapsed buildings overnight in search of survivors. Witnesses described a devastating scene with large-scale carnage, as doctors worked feverishly to attend to the dead and injured, many badly burned.

“The hospital is overwhelmed by both dead and wounded,” Dr. Mohamed Yusuf, the director of Medina hospital located near the blast, told the Associated Press. “We also received people whose limbs were cut away by the bomb. This is really horrendous, unlike any other time in the past.”

Photos and videos of the bombing, which took place on a busy street near a section of the city housing foreign embassies, showed collapsed walls, twisted metal, and sporadic fires spewing smoke. The Qatari government said its embassy was “severely damaged” in the strike.

There should be an embedded item here. Please visit the original post to view it.

Family members searched through the wreckage and waited at local hospitals with the hopes of finding relatives who survived the bombing.

Somali President Mohamed Abdullahi Mohamed announced three days of mourning. The attacks received international condemnation, including from the United States.

Iraqi, Kurdish forces in standoff, weeks after Kurdish vote for independence

Watch Video | Listen to the Audio

HARI SREENIVASAN: The desire of the Kurds along Iraq’s northern border to govern themselves is receiving more resistance from Iraq’s central government. Iraqi army forces are demanding Kurdish troops withdraw from oil fields and military bases around Kirkuk, a city in the Kurdistan region that voted for independence last month. Kirkuk also has 10% of Iraq’s known oil reserves. Washington Post’s Loveday Morris is in Baghdad covering this standoff joins me now via Skype. First of all the significance of this. Why is it so important?

LOVEDAY MORRIS: There’s been a longtime conflict between Baghdad and Kurdistan over these disputed territories. Most significant of which is Kirkuk because of the oil reserves. But the referendum last month has really sharpened these disputes because you have Baghdad opposing independence and so it feels like they have to restate its territorial claims these areas. So that’s why we’re seeing a lot of tension right now.

HARI SREENIVASAN: And just to give people a little bit of a brief timeline – Iraqi forces control this area for a while and then in June ISIS took over the area and now it’s kind of back in Kurdish hands?

LOVEDAY MORRIS: Right. So in June 2014 Iraq lost control of a lot of the areas and we have this huge collapse in the face of an ISIS offensive. Over 100,000 soldiers fled and Kurdish forces moved in some of these areas – some of them maybe took from ISIS and others just moved into into the vacuum. And so Iraqi forces have been in these areas since June 2014. And that’s their main demand that they return to the areas.

HARI SREENIVASAN: What’s the likelihood that this standoff right now turns violent? Into some sort of a civil war?

LOVEDAY MORRIS:: I think at this point both sides don’t want violence. Al-Abadi, the prime minister, is really trying to defuse the situation by saying there’s going to be no military attack. But at the same time there is this buildup of forces so that I think they are trying to, in a way, intimidate the Kurds to withdraw from some areas but they don’t want to see a fight per say. But in this really tense situation there can be a small spark and things can turn violent quite easily.

HARI SREENIVASAN: Thank you.

News Wrap: Dozens missing after deadly Mogadishu truck bombing

Watch Video | Listen to the Audio

JUDY WOODRUFF: And in the day’s other news: More than 300 people are now confirmed dead after Saturday’s massive truck bombing in Somalia, one of the world’s worst attacks in years.

Nearly 400 more were wounded. The government blamed the al-Qaida-linked Al-Shabaab group. Rescue crews today searched for survivors at the scene of the bombing, a crowded street in the capital, Mogadishu. With dozens still missing, officials say they expect the death toll to rise.

OSMAN LIBAH IBRAHIM, Deputy Minister for Natural Resources, Somalia (through interpreter): More bodies are gradually being found and removed from the rubble. There are other people who are under the rubble. We have heard them as they scream for help. My biggest worry is that even the wounded are succumbing to their injuries.

JUDY WOODRUFF: The attack happened two days after Somalia’s defense minister and army chief resigned for undisclosed reasons.

There’s been yet another shift to the right in European politics; 31-year-old conservative Sebastian Kurz, Austria’s foreign minister, is set to become that country’s next leader. But he’s short of a majority in Parliament and will likely form a coalition with the far-right Freedom Party. It was founded by ex-Nazis in the 1950s.

Kurz has called for the European Union to focus more on internal trade and securing borders. He celebrated in Vienna.

SEBASTIAN KURZ, Austrian People’s Party (through interpreter): I have a big request for you. Use today to celebrate. You all have earned it through hard work and dedication. At the same time, I need to tell you that tomorrow the work starts. We didn’t just run to win the elections. We did so to bring Austria back to the top. We ran in this election to achieve real change.

JUDY WOODRUFF: A final result in the election is likely to be decided on Thursday.

Wildfires that broke out over the weekend in Portugal have killed at least 35 people, including a one-month-old infant. Today, more than 5,300 firefighters with some 1,600 vehicles were battling the fires, some of which officials say were started by arsonists. Wildfires have also left at least four people dead in neighboring Spain.

Army Sergeant Bowe Bergdahl pleaded guilty today to desertion and misbehavior before the enemy. He was captured by the Taliban in 2009, after leaving his post in Afghanistan. It prompted an intense search and a prisoner swap. Bergdahl appeared before a military judge in Fort Bragg, North Carolina, today. The 31-year-old could be sentenced to life in prison. He said his actions were very inexcusable, adding he didn’t — quote — “think there’d be any reason to pull off a crucial mission to look for one guy.”

The truck driver in deadly immigrant smuggling run has pleaded guilty in court. San Antonio police found at least 39 immigrants, 10 of whom died, packed into a sweltering semi-trailer last year and died. The driver, James Matthew Bradley Jr., pleaded to conspiracy and transporting immigrants, resulting in death. He faces now up to life in prison.

A New Jersey man has been convicted of planting two pressure-cooker bombs on New York City streets last year. Ahmed Khan Rahimi faces a maximum sentence of life in prison for charges including using a weapon of mass destruction. One of the bombs exploded in Manhattan’s Chelsea neighborhood, wounding 30. The second didn’t detonate. Officials said Rahimi was inspired by ISIS and al-Qaida.

JOHN MILLER, Deputy Commissioner, NYPD Intelligence & Counterterrorism: Ahmed Khan Rahimi learned a lesson which we keep reminding people of. This is the wrong place to try and carry out an act of terrorism. Witnesses will come forward, evidence will be developed, arrests will be made, prosecutions will be brought forth, and they will be successful.

JUDY WOODRUFF: Prosecutors said Rahimi also planted a pipe bomb in Seaside Heights, New Jersey, but no one was injured.

Colin Kaepernick has filed a grievance against the national football league. The former San Francisco 49ers quarterback says that he remains unsigned due to collusion by team owners over his national anthem protests. Kaepernick sparked a debate when he kneeled during the anthem last year, protesting police mistreatment of African-Americans.

On Wall Street today, the Dow Jones industrial average gained 85 points to close at 22957. The Nasdaq rose 18. And the S&P 500 added four.

It was a milestone day in the world of astronomy. For the first time, researchers say they have detected gravitational waves with a flash of light from the same cosmic event. The dual observation supports Albert Einstein’s general theory of relativity. The ripples in space and the light burst were caused by the collision of two neutron stars. They were first detected in August.

Sony Discusses What Lessons Can be Learned from the Failure of Concord

Sony president Hiroki Totoki in a Q&A session with investors was asked about the failure of Concord, which was shut down less than two weeks after it released.

"Currently, we are still in the process of learning," said Totoki (via VideoGamesChronicle). "And basically, with regards to new IP, of course, you don’t know the result until you actually try it.

"So for us, for our reflection, we probably need to have a lot of gates, including user testing or internal evaluation, and the timing of such gates. And then we need to bring them forward, and we should have done those gates much earlier than we did.

"Also, we have a siloed organisation, so going beyond the boundaries of those organisations in terms of development, and also sales, I think that could have been much smoother.

"And then going forward, in our own titles and in third-party titles, we do have many different windows. And we want to be able to select the right and optimal window so that we can deploy them on our own platform without cannibalization, so that we can maximize our performance in terms of title launches. That’s all I have."

Sony senior vice president for finance and IR Sadahiko Hayakawa discussed the success of Helldivers 2 and the failure of Concord.

"We launched two live-service games this year," he said. "Helldivers 2 was a huge hit, while Concord ended up being shut down. We gained a lot of experience and learned a lot from both.

"We intend to share the lessons learned from our successes and failures across our studios, including in the areas of title development management as well as the process of continually adding expanded content and scaling the service after its release so as to strengthen our development management system.

"We intend to build on an optimum title portfolio during the current mid-range plan period that combines single-player games – which are our strengths and which have a higher predictability of becoming hits due to our proven IP – with live-service games that pursue upside while taking on a certain amount of risk upon release."

Concord released for the PlayStation 5 and PC on August 23, and it was shut down on September 6.
