Germany's main political parties have agreed to hold a general election in February, following the collapse of the ruling coalition government earlier this month. As Henry Ridgwell reports, the vote could have big implications for Ukrainian military aid — just as Europe prepares for U.S. President-elect Donald Trump's second term.

MEXICO CITY — Cassandra Garduño squinted in the sunlight, her pink boots smudged by dirt as she gazed out over her family's chinampa — one of the islands first built up by the Aztecs with fertile mud from the bottom of a lake that, later drained, would one day become Mexico City. Food from these islands has fed people for hundreds of years, but the chinampas are under threat from urbanization. The produce grown here doesn't fetch much money, and many families are abandoning the ancient practice to rent out or sell their land for more lucrative uses such as soccer fields. "People don't want to farm anymore," said Garduño. "They don't see it as a necessity, they don't want to produce, and people don't want to buy the products." Some of those remaining, like Garduño, are banding together to preserve and promote the traditional use of the chinampas. "None of this can exist without human hands, the hands of those who worked here and created the chinampa a thousand years ago," she said on a recent morning as the smell of celery growing nearby filled the air. The gardens crisscrossed by canals in the capital's southern Xochimilco borough are built up from layers of dredged soil, held together by tall, thin ahuejotes — a kind of willow tree — planted around their perimeter. Xochimilco has more than 2,500 acres of protected land owned by generations of local chinamperos, as those who farm the islands are known. Garduño's earliest memories of her family's chinampa came from peering through her grandparents' window at the plot of land and watching canoes weave in and out of the canals. Even then, she saw how the chinampas were deteriorating under pressure from urbanization and as some farmers began to drop the practice. When her grandfather died in 2010 and her uncles didn't want to carry on, Garduño took it upon herself to learn and conserve generations of farming. Her neighbors and relatives were skeptical at first, but she bought land for her own chinampa from a friend's uncle in 2020 and now grows an assortment of produce, including sunflowers, eggplant, and the Mexican marigold "cempasuchil." Now the 32-year-old Garduño is one of the growing collective called Chinampa Refuge, started by the National Autonomous University of Mexico, and she and other famers encourage chinamperos to preserve their land. They follow ancient growing techniques but are trying new commercial approaches to compete with cheaper produce grown on massive farms elsewhere in Mexico. That includes a special tag — Etiqueta Chinampera — that tells buyers the produce came from a chinampa, and may tout things like water quality or the chinampa's status as a biodiversity refuge. "Change comes with educating the new generations," said Garduño. "Talking about the origins and efforts to conserve and why it's important to do it." Luis Zambrano, an ecologist from the National Autonomous University of Mexico who has worked in Xochimilco for decades, said the fields are largely self-sustaining. Nourished by the lake, they can produce three to five crops of vegetables a year without the need of chemicals or irrigation, he said. Moreover, the ecosystem of Xochimilco benefits the sprawling city. Many different species of birds and fish thrive there, and the extensive canals help reduce the city's overall temperature, he said. But now, on weekends, it's common to see more soccer players boating to islands in their jerseys and cleats than farmers tending their crops. The soccer fields stretch for miles along the canals after what Zambrano called "a massive increase" over the past two to three years. In Xochimilco, many people are reluctant to talk about transforming their chinampas to soccer fields. One landowner who declined to be identified for fear of legal or community backlash said keeping the chinampas productive required more work and financial investment and yielded less revenue. Instead, she has established multiple businesses on her land — a soccer field for weekend games, a food stand and kayaking tours for foreign visitors. "If you do well (farming) you could earn $5,000 to $10,000 (100,000 to 200,000 pesos) a year," Garduño said. "In the tourist area you could have that within a couple of weekends." But converting the agricultural fields carries ecological impact. While traditional farming methods avoid insecticides and fertilizers, the soccer fields are another story. "It doesn't look that detrimental because there's no construction," said Zambrano. But "it's just as damaging because the amount of chemicals that are used, the amount of pollution that is generated is very, very large." The chinampas are among the significant features that led Mexico City's historic center and Xochimilco to be recognized as a world heritage site by UNESCO. But any protective measures are up to federal, state and local authorities. Carlos Vasquez, director of the Natural Protected Areas under Mexico City's Environmental Department, said they are working on proposals to address the soccer fields. "Many are counter to the conservation of the ecosystems," he said. "We're looking to regulate these activities." After a long day's work out in the sun, Garduño and some neighboring farmers congregate under Garduño's makeshift hut for a feast of chicken and tortillas. They catch up on their tasks and outline what's left to do. Juan Ávalos, 63, and his brother Salvador Gonzalez Ávalos, 55, have been working on chinampas all their lives. Their family has several plots in Xochimilco's San Gregorio neighborhood. A year ago, after some convincing by Garduño, the brothers joined Chinampa Refuge to adopt a more holistic approach to their farming. Salvador said the approach is a continuous reminder of his family's legacy in maintaining the ancient practices — something they want to pass on to their grandchildren. "That's something we need to work on as grandparents," he said. "That they integrate themselves with a taste for this earth."

Background:

Higher trust in healthcare providers has been linked to better health outcomes and satisfaction. Lower trust has been associated with healthcare-based discrimination.

Purpose Health care professionals (HCPs) working collaboratively can improve patient outcomes and also increase their understanding of each other’s professional roles. This descriptive study aimed to explore dental hygienists’ perceptions of collaboration with dentists and intraprofessional educational (IntraPE) experiences.Methods A convenience sampling method was used to assess DHs perceptions of collaboration with dentists using the Interprofessional Collaboration Scale (ICS), a validated scale that measures perceptions of communication, accommodation, and isolation among HCPs. One open-ended question was added to explore IntraPE. Demographics, work characteristics and responses from the ICS were analyzed using frequency, mean, standard deviation, Pearson’s correlation, t-test, ANOVA, and multivariable regression. Responses from the open-ended question were transcribed, organized, and coded. Themes were identified using the Delve Qualitative Analysis Tool.Results Of the 264 participants, the average age was 38.9, and most identified as female (98.9%). Data analysis revealed that DHs had positive perceptions of collaboration with dentists. Significant relationships were found between ICS factor accommodation and the average number of patients treated per day (rs = −0.242, p<0.001), dentists’ age (rs = −.145, p<0.05). Isolation showed a significant negative correlation with the average number of patients treated per day (rs = −0.156, p<0.05). Most reported having no opportunities for IntraPE education experiences with dentists. Five categories of themes were identified from the open-ended question: shared academic setting, clinic dentist, externships, desire for more shared learning, and shared patient experiences.Conclusion Dental hygienists in this study had an overall more positive than negative perception of collaboration with dentists. Dental and dental hygiene programs should focus on intraprofessional education experiences to continue to enhance collaboration.

Purpose The posterior superior alveolar (PSA) block injection is one of many techniques used to provide profound anesthesia for invasive dental procedures. This technique has a high success rate but is not without complication risks. The purpose of this study was to determine if pulpal anesthesia of the maxillary second molar could be achieved using a reduced needle depth of 10mm or 5mm compared to the traditional needle depth of 16mm.Methods Sixty participants were asked to participate in three sessions. Each session started with a pre neural response test, followed by one randomized needle depth PSA injection, and ending with a post neural response test. The neural response test consisted of two parts, a cold refrigerant and a dental probe, on the buccal and interproximal surface of the maxillary second molar. After receiving a positive neural response, each participant received a posterior superior alveolar block injection using a short (21mm), 27-gauge dental needle with a randomized needle penetration depth of 16mm, 10mm, or 5mm. A post neural response test consisting of the same two parts as the pre-test was conducted on the maxillary second molar to evaluate for profound anesthesia.Results Positive neural responses were obtained from 100% of the participants (n=167) during the pre-tests. Study results demonstrated an 85% success rate at the traditional 16mm needle depth and a 93% and 92% success rates for the reduced needle depths of 10mm and 5mm, respectively. Pulpal anesthesia of the maxillary second molar had been achieved at all three needle depths with no statistically significant difference in the rate of success. Furthermore, there were no adverse events observed.Conclusion The reduced needle depth technique showed promise in achieving desired results of pulpal anesthesia with a reduced risk for complications associated with the PSA block injection. Additional studies are recommended to achieve evidence-based support for this reduced needle depth technique.

ABSTRACTWe describe the development, implementation, and evaluation of a novel twinning approach: the Twinning Partnership Network (TPN). Twinning is a well-known approach to peer learning that has been used in a variety of settings to build organizational capacity. Although twinning takes many forms, the heart of the approach is that institutions with shared characteristics collaborate via sharing information and experiences to achieve a specific goal. We adapted a twinning partnership strategy developed by the World Health Organization to create a network of like-minded health institutions. The key innovation of the TPN is the network, which ensures that an institution always has a high-performing peer with whom to partner on a specific topic area of interest. We identified 10 hospitals and 30 districts in Rwanda to participate in the TPN. These districts and hospitals participated in a kickoff workshop in which they identified capacity gaps, clarified goals, and selected twinning partners. After the workshop, districts and hospitals participated in exchange visits, coaching visits, and virtual and in-person learning events. We found that districts and hospitals that selected specific areas and worked on them throughout the duration of the TPN with their peers improved their performance significantly when compared with those that selected and worked on other areas. Accreditation scores improved by 5.6% more in hospitals selecting accreditation than those that did not. Districts that selected improving community-based health insurance coverage improved by 4.8% more than districts that did not select this topic area. We hypothesize that these results are due to senior management’s interest and motivation to improve in these specific areas, the motivation gained by learning from high-performing peers with similar resources, and context-specific knowledge sharing from peer hospitals and districts.

Mitochondrial dysfunction is a hallmark of many genetic neurodegenerative diseases, but therapeutic options to reverse mitochondrial dysfunction are limited. While recent studies support the possibility of improving mitochondrial fusion/fission dynamics and motility to correct mitochondrial dysfunction and resulting neurodegeneration in Charcot-Marie-Tooth disease (CMT) and other neuropathies, the clinical utility of reported compounds and relevance of preclinical models are uncertain. Here, we describe motor and sensory neuron dysfunction characteristic of clinical CMT type 2 A in a CRISPR/Casp-engineered Mfn2 Thr105Met (T105M) mutant knock-in mouse. We further demonstrate that daily oral treatment with a novel mitofusin activator derived from the natural product piperine can reverse these neurologic phenotypes. Piperine derivative 8015 promoted mitochondrial fusion and motility in Mfn2-deficient cells in a mitofusin-dependent manner and reversed mitochondrial dysfunction in cultured fibroblasts and reprogrammed motor neurons from a human CMT2A patient carrying the MFN2 T105M mutation. Like previous mitofusin activators, 8015 exhibited stereospecific functionality, but the more active stereoisomer, 8015-P2, is unique in that it has subnanomolar potency and undergoes entero-hepatic recirculation which extends its in vivo half-life. Daily administration of 8015-P2 to Mfn2 T105M knock-in mice for 6 weeks normalized neuromuscular and sensory dysfunction and corrected histological/ultrastructural neurodegeneration and neurogenic myoatrophy. These studies describe a more clinically relevant mouse model of CMT2A and an improved mitofusin activator derived from piperine. We posit that 8015-P2 and other piperine derivatives may benefit CMT2A or other neurodegenerative conditions wherein mitochondrial dysdynamism plays a contributory role.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy treatment, routinely manifesting as increased pain sensitivity (allodynia) in distal extremities. Despite its prevalence, effective treatment options are limited. Cannabinoids are increasingly being evaluated for their ability to treat chronic pain conditions, including CIPN. While previous studies have revealed sex differences in cannabinoid-mediated antinociception in acute and chronic pain models, there is a paucity of studies addressing potential sex differences in the response of CIPN to cannabinoid treatment. Therefore, we evaluated the long-term antiallodynic efficacy of cannabinoid receptor type 1 (CB₁)-selective, cannabinoid receptor type 2 (CB₂)-selective, and CB₁/CB₂ mixed agonists in the cisplatin CIPN model, using both male and female mice. CB₁ selective agonism was observed to have sex differences in the development of tolerance to antiallodynic effects, with females developing tolerance more rapidly than males, while the antiallodynic effects of selective CB₂ agonism lacked tolerance development. Compound-specific changes to the female estrous cycle and female plasma estradiol levels were noted, with CB₁ selective agonism decreasing plasma estradiol while CB₂ selective agonism increased plasma estradiol. Chronic administration of a mixed CB₁/CB₂ agonist resulted in increased mRNA expression of proinflammatory cytokines and endocannabinoid regulatory enzymes in female spinal cord tissue. Ovarian tissue was noted to have proinflammatory cytokine mRNA expression following administration of a CB₂ acting compound while selective CB₁ agonism resulted in decreased proinflammatory cytokines and endocannabinoid regulatory enzymes in testes. These results support the need for further investigation into the role of sex and sex hormones signaling in pain and cannabinoid-mediated antinociceptive effects.

Neuropathic pain is a form of chronic pain that develops because of damage to the nervous system. Treatment of neuropathic pain is often incompletely effective, and most available therapeutics have only moderate efficacy and present side effects that limit their use. Opioids are commonly prescribed for the management of neuropathic pain despite equivocal results in clinical studies and significant abuse potential. Thus, neuropathic pain represents an area of critical unmet medical need, and novel classes of therapeutics with improved efficacy and safety profiles are urgently needed. The cannabidiol structural analog and novel antagonist of GPR55, KLS-13019, was screened in rat models of neuropathic pain. Tactile sensitivity associated with chemotherapy exposure was induced in rats with once-daily 1-mg/kg paclitaxel injections for 4 days or 5 mg/kg oxaliplatin every third day for 1 week. Rats were then administered KLS-13019 or comparator drugs on day 7 in an acute dosing paradigm or days 7–10 in a chronic dosing paradigm, and mechanical or cold allodynia was assessed. Allodynia was reversed in a dose-dependent manner in the rats treated with KLS-13019, with the highest dose reverting the response to prepaclitaxel injection baseline levels with both intraperitoneal and oral administration after acute dosing. In the chronic dosing paradigm, four consecutive doses of KLS-13019 completely reversed allodynia for the duration of the phenotype in control animals. Additionally, coadministration of KLS-13019 with paclitaxel prevented the allodynic phenotype from developing. Together, these data suggest that KLS-13019 represents a potential new drug for the treatment of neuropathic pain.

[¹⁷⁷Lu]Lu-PSMA-617 was approved by the U.S. Food and Drug Administration for patients with prostate-specific membrane antigen (PSMA)–positive metastatic castration-resistant prostate cancer (mCRPC). Since the time of regulatory approval, however, real-world data have been lacking. This study investigated the efficacy, safety, and outcome predictors of [¹⁷⁷Lu]Lu-PSMA-617 at a major U.S. academic center. Methods: Patients with mCRPC who received [¹⁷⁷Lu]Lu-PSMA-617 at the Johns Hopkins Hospital outside clinical trials were screened for inclusion. Patients who underwent [¹⁷⁷Lu]Lu-PSMA-617 and had available outcome data were included in this study. Outcome data included prostate-specific antigen (PSA) response (≥50% decline), PSA progression-free survival (PFS), and overall survival (OS). Toxicity data were evaluated according to the Common Terminology Criteria for Adverse Events version 5.03. The study tested the association of baseline circulating tumor DNA mutational status in homologous recombination repair, PI3K alteration pathway, and aggressive-variant prostate cancer–associated genes with treatment outcome. Baseline PSMA PET/CT images were analyzed using SelectPSMA, an artificial intelligence algorithm, to predict treatment outcome. Associations with the observed treatment outcome were evaluated. Results: All 76 patients with PSMA-positive mCRPC who received [¹⁷⁷Lu]Lu-PSMA-617 met the inclusion criteria. A PSA response was achieved in 30 of 74 (41%) patients. The median PSA PFS was 4.1 mo (95% CI, 2.0–6.2 mo), and the median OS was 13.7 mo (95% CI, 11.3–16.1 mo). Anemia of grade 3 or greater, thrombocytopenia, and neutropenia were observed in 9 (12%), 3 (4%), and 1 (1%), respectively, of 76 patients. Transient xerostomia was observed in 23 (28%) patients. The presence of aggressive-variant prostate cancer–associated genes was associated with a shorter PSA PFS (median, 1.3 vs. 6.3 mo; P = 0.040). No other associations were observed between circulating tumor DNA mutational status and treatment outcomes. Eighteen of 71 (25%) patients classified by SelectPSMA as nonresponders had significantly lower rates of PSA response than patients classified as likely responders (6% vs. 51%; P < 0.001), a shorter PSA PFS (median, 1.3 vs. 6.3 mo; P < 0.001), and a shorter OS (median, 6.3 vs. 14.5 mo; P = 0.046). Conclusion: [¹⁷⁷Lu]Lu-PSMA-617 offered in a real-world setting after regulatory approval in the United States demonstrated antitumor activity and a favorable toxicity profile. Artificial-intelligence–based analysis of baseline PSMA PET/CT images may improve patient selection. Validation of these findings on larger cohorts is warranted.

Both preclinical and clinical studies implicate functional impairments of several neuroactive metabolites of the kynurenine pathway (KP), the major degradative cascade of the essential amino acid tryptophan in mammals, in the pathophysiology of neurologic and psychiatric diseases. A number of KP enzymes, such as tryptophan 2,3-dioxygenase (TDO2), indoleamine 2,3-dioxygenases (IDO1 and IDO2), kynurenine aminotransferases (KATs), kynurenine 3-monooxygenase (KMO), 3-hydroxyanthranilic acid oxygenase (3-HAO), and quinolinic acid phosphoribosyltransferase (QPRT), control brain KP metabolism in health and disease and are therefore increasingly considered to be promising targets for the treatment of disorders of the nervous system. Understanding the distribution, cellular expression, and regulation of KP enzymes and KP metabolites in the brain is therefore critical for the conceptualization and implementation of successful therapeutic strategies.

BACKGROUND AND PURPOSE:

Periprocedural intracranial hemorrhage is one of common complications after stent placement for symptomatic intracranial atherosclerotic stenosis. This study was conducted to demonstrate predictors and long-term outcomes of periprocedural intracranial hemorrhage after stent placement for symptomatic intracranial atherosclerotic stenosis.

BACKGROUND AND PURPOSE:

Mechanical thrombectomy is a fundamental intervention for acute ischemic stroke treatment. While conventional techniques are effective, cyclic aspiration (CyA) shows potential for better recanalization rates. We aim to investigate factors affecting CyA and compare them with static aspiration (StA).

SUMMARY:

Vascular inflammation is widely recognized as an important factor in the atherosclerotic process, particularly in terms of plaque development and progression. Conventional tests, such as measuring circulating inflammatory biomarkers, lack the precision to identify specific areas of vascular inflammation. In this context, noninvasive imaging modalities can detect perivascular fat changes, serving as a marker of vascular inflammation. This review aims to provide a comprehensive overview of the key concepts related to perivascular carotid fat and its pathophysiology. Additionally, we examine the existing literature on the association of pericarotid fat with features of plaque vulnerability and cerebrovascular events. Finally, we scrutinize the advantages and limitations of the noninvasive assessment of pericarotid fat.

BACKGROUND

For many patients with post–COVID-19 condition (long COVID), primary care is the first point of interaction with the health care system. In principle, primary care is well situated to manage long COVID. Beyond expressions of disempowerment, however, the patient’s perspective regarding the quality of long COVID care is lacking. Therefore, this study aimed to analyze the expectations and experiences of primary care patients seeking treatment for long COVID.

After nearly a year of public beta honing, the Nvidia App – Team Green’s new one-stop shop for desktop GPU management – is out in full. Not alongside the upcoming RTX 50 series, as rumoured, but right-now-today-this-minute. I’ve been testing out the launch version and while it’s not without some dud features, it does agreeably achieve its stated goal of combining the functions within Nvidia Control Panel and GeForce Experience. And if installing it means never having to use the latter again, well, that’s 149MB well spent.

The future of engineering is bright, and it’s being shaped by the young minds at the TryEngineering Summer Institute (TESI), a program administered by IEEE Educational Activities. This year more than 300 students attended TESI to fuel their passion for engineering and prepare for higher education and careers. Sessions were held from 30 June through 2 August on the campuses of Rice University, the University of Pennsylvania, and the University of San Diego.

The program is an immersive experience designed for students ages 13 to 17. It offers hands-on projects, interactive workshops, field trips, and insights into the profession from practicing engineers. Participants get to stay on a college campus, providing them with a preview of university life.

Student turned instructor

One future innovator is Natalie Ghannad, who participated in the program as a student in 2022 and was a member of this year’s instructional team in Houston at Rice University. Ghannad is in her second year as an electrical engineering student at the University of San Francisco. University students join forces with science and engineering teachers at each TESI location to serve as instructors.

For many years, Ghannad wanted to follow in her mother’s footsteps and become a pediatric neurosurgeon. As a high school junior in Houston in 2022, however, she had a change of heart and decided to pursue engineering after participating in the TESI at Rice. She received a full scholarship from the IEEE Foundation TESI Scholarship Fund, supported by IEEE societies and councils.

“I really liked that it was hands-on,” Ghannad says. “From the get-go, we were introduced to 3D printers and laser cutters.”

The benefit of participating in the program, she says, was “having the opportunity to not just do the academic side of STEM but also to really get to play around, get your hands dirty, and figure out what you’re doing.”

“Looking back,” she adds, “there are so many parallels between what I’ve actually had to do as a college student, and having that knowledge from the Summer Institute has really been great.”

She was inspired to volunteer as a teaching assistant because, she says, “I know I definitely want to teach, have the opportunity to interact with kids, and also be part of the future of STEM.”

More than 90 students attended the program at Rice. They visited Space Center Houston, where former astronauts talked to them about the history of space exploration.

Participants also were treated to presentations by guest speakers including IEEE Senior Member Phil Bautista, the founder of Bull Creek Data, a consulting company that provides technical solutions; IEEE Senior Member Christopher Sanderson, chair of the IEEE Region 5 Houston Section; and James Burroughs, a standards manager for Siemens in Atlanta. Burroughs, who spoke at all three TESI events this year, provided insight on overcoming barriers to do the important work of an engineer.

Learning about transit systems and careers

The University of Pennsylvania, in Philadelphia, hosted the East Coast TESI event this year. Students were treated to a field trip to the Southeastern Pennsylvania Transportation Association (SEPTA), one of the largest transit systems in the country. Engineers from AECOM, a global infrastructure consulting firm with offices in Philadelphia that worked closely with SEPTA on its most recent station renovation, collaborated with IEEE to host the trip.

Participants also heard from guest speakers including Api Appulingam, chief development officer of the Philadelphia International Airport, who told the students the inspiring story of her career.

Guest speakers from Google and Meta

Students who attended the TESI camp at the University of San Diego visited Qualcomm. Hosted by the IEEE Region 6 director, Senior Member Kathy Herring Hayashi, they learned about cutting-edge technology and toured the Qualcomm Museum.

Students also heard from guest speakers including IEEE Member Andrew Saad, an engineer at Google; Gautam Deryanni, a silicon validation engineer at Meta; Kathleen Kramer, 2025 IEEE president and a professor of electrical engineering at the University of San Diego; as well as Burroughs.

“I enjoyed the opportunity to meet new, like-minded people and enjoy fun activities in the city, as well as get a sense of the dorm and college life,” one participant said.

Hands-on projects

In addition to field trips and guest speakers, participants at each location worked on several hands-on projects highlighting the engineering design process. In the toxic popcorn challenge, the students designed a process to safely remove harmful kernels. Students tackling the bridge challenge designed and built a span out of balsa wood and glue, then tested its strength by gradually adding weight until it failed. The glider challenge gave participants the tools and knowledge to build and test their aircraft designs.

One participant applauded the hands-on activities, saying, “All of them gave me a lot of experience and helped me have a better idea of what engineering field I want to go in. I love that we got to participate in challenges and not just listen to lectures—which can be boring.”

The students also worked on a weeklong sparking solutions challenge. Small teams identified a societal problem, such as a lack of clean water or limited mobility for senior citizens, then designed a solution to address it. On the last day of camp, they pitched their prototypes to a team of IEEE members that judged the projects based on their originality and feasibility. Each student on the winning teams at each location were awarded the programmable Mech-5 robot.

Twenty-nine scholarships were awarded with funding from the IEEE Foundation. IEEE societies that donated to the cause were the IEEE Computational Intelligence Society, the IEEE Computer Society, the IEEE Electronics Packaging Society, the IEEE Industry Applications Society, the IEEE Oceanic Engineering Society, the IEEE Power & Energy Society, the IEEE Power Electronics Society, the IEEE Signal Processing Society, and the IEEE Solid-State Circuits Society.
