President Bush said last week that his thinking on the U.S. situation in Iraq was informed by an analogy: the October 2000 bombing of the USS Cole in Yemen. The lack of a sufficient American response to that and other al-Qaeda attacks, Bush said, led to the Sept. 11, 2001, attacks.

Here is a measure of the state of the war in Iraq: The number of Iraqis dying each month now rivals the total number of people who died in the Sept. 11, 2001, attacks.

Across Europe, grassroots efforts have emerged in the wake of crisis that draw members of the public into the process of receiving refugees and supporting their integration. This policy brief examines the many forms community-based or private sponsorship can take, what benefits such approaches may hold for European communities, and the tradeoffs policymakers face in their implementation.

Home visiting programs for young families are growing in popularity across the United States, and have demonstrated their effectiveness in supporting maternal health and child well-being. At the same time, more infants and toddlers are growing up in immigrant families and households where a language other than English is spoken. Why then are these children under-represented in these programs? This brief explores common barriers, ways to address them, and why it is important to do so.

"This study contributes to the limited evidence available on how invitational narrative approaches are used in the domestic and family violence field. It focused on invitational narrative ways of engaging and working with men who perpetrate domestic and family violence. Focusing on the processes and skills of practice embedded in invitational narrative ideas enabled the examination of different ways of engaging men that have the potential to lead to sustained change. Accordingly, the main aim of this study was to explore invitational narrative ways of working in order to build an understanding of the processes and skills that engage men and enable behavioural and attitudinal change." --Executive summary (page 6).

The Washington Capitals on Friday placed Brendan Leipsic on unconditional waivers to terminate his contract after he made disparaging comments about women and teammates in a private social media chat. In a conversation involving his brother and Florida Panthers minor leaguer Jack Rodewald, Leipsic commented on the physical appearances of Vancouver forward Tanner Pearson's wife and Edmonton captain Connor McDavid's girlfriend. The NHL called it ''inexcusable conduct'' and said it would address the matter with the Capitals and Panthers.

Segmentation of cardiac images, particularly late gadolinium-enhanced magnetic resonance imaging (LGE-MRI) widely used for visualizing diseased cardiac structures, is a crucial first step for clinical diagnosis and treatment. However, direct segmentation of LGE-MRIs is challenging due to its attenuated contrast. Since most clinical studies have relied on manual and labor-intensive approaches, automatic methods are of high interest, particularly optimized machine learning approaches. To address this, we organized the "2018 Left Atrium Segmentation Challenge" using 154 3D LGE-MRIs, currently the world's largest cardiac LGE-MRI dataset, and associated labels of the left atrium segmented by three medical experts, ultimately attracting the participation of 27 international teams. In this paper, extensive analysis of the submitted algorithms using technical and biological metrics was performed by undergoing subgroup analysis and conducting hyper-parameter analysis, offering an overall picture of the major design choices of convolutional neural networks (CNNs) and practical considerations for achieving state-of-the-art left atrium segmentation. Results show the top method achieved a dice score of 93.2% and a mean surface to a surface distance of 0.7 mm, significantly outperforming prior state-of-the-art. Particularly, our analysis demonstrated that double, sequentially used CNNs, in which a first CNN is used for automatic region-of-interest localization and a subsequent CNN is used for refined regional segmentation, achieved far superior results than traditional methods and pipelines containing single CNNs. This large-scale benchmarking study makes a significant step towards much-improved segmentation methods for cardiac LGE-MRIs, and will serve as an important benchmark for evaluating and comparing the future works in the field.

If the coronavirus breaks as bad we fear, a lot more people are going to be working from home. These business messaging apps can help teams stay in touch, and stay productive, even if they can't come in to the office.

Stronger data practices can help leaders better utilize data as a way to deeply understand the students they serve.

READING about the Brooks family and their foraging for food (“Family serves a dinner-time treat ... Japanese Knotweed crumble”, The Herald, May 2) provoked very happy memories of another forager-par-excellence; Rosalind Burgess, the Skye weaver, cook, and writer of an excellent book on how to use the things you grow and forage.

Cross-sectional imaging can reduce the negative appendectomy rate (NAR) in children being evaluated for suspected appendicitis; however, the ability of diagnostic imaging to decrease NAR may vary by age and gender.

Cross-sectional imaging leads to a significant reduction in NAR for children younger than 5 years and girls older than 10 years. For boys older than 5 years being evaluated for uncomplicated appendicitis, advanced imaging appears to have limited value. (Read the full article)

Sending and receiving sexually explicit picture and text messages via cell phone (ie, "sexting") among adolescents is publicized as a societal and public health concern, yet it is unknown whether sexting is associated with physical sexual activity or sexual risk behavior.

This study is the first to examine sexting among a probability sample of adolescents and found that sexting is associated with sexual activity, sexual risk behavior, and knowing other person(s) who have sent a sext. (Read the full article)

Retinal hemorrhages occur in accidental and inflicted traumatic brain injury (ITBI) and some medical encephalopathies. Large numbers and peripherally located retinal hemorrhages are frequently cited as distinguishing features of ITBI in infants, but the predictive value has not been established.

This prospective retinal imaging study found that a diagnosis of ITBI in infants and children can be distinguished from other traumatic and nontraumatic causes by the presence of >25 dot-blot (intraretinal layer) hemorrhages (positive predictive value = 93%). (Read the full article)

Medical imaging that uses ionizing radiation provides notable benefits in the clinical setting. Controversy regarding increased cancer risk, particularly in children, dictates that ordering practices and use of such medical imaging be evaluated to reduce unnecessary exposure to imaging-related radiation.

We evaluated the prevalence and characteristics of diagnostic imaging procedures in children. The proportion of higher radiation procedures is increasing, especially among children evaluated in the inpatient and emergency department settings and those with gastrointestinal and neurologic symptoms, and congenital anomalies.

Gaining intravenous access in children can be difficult. Recently, several near-infrared devices have been introduced attempting to support intravenous cannulation by visualizing veins underneath skin. Only one of those devices has been evaluated systemically thus far and results are inconclusive.

Although it was possible to visualize veins with near-infrared in most patients, the VascuLuminator did not improve the success of cannulation. An explanation is that the main problem is probably not localization of the vein but insertion of the cannula. (Read the full article)

Because pediatric appendicitis is challenging to diagnose, computed tomography (CT) is used frequently. Childhood radiation exposure is associated with increased risk of cancer. Ultrasound avoids radiation exposure but is less sensitive for appendicitis than CT.

Controlling for referral bias, evaluation at a community compared with a children’s hospital is associated with higher CT and lower ultrasound use before appendectomy. CT and ultrasound accuracy for appendicitis in children varies with hospital type. (Read the full article)

There is a lack of consensus regarding the optimal investigative approach after a first febrile urinary tract infection. This is because of uncertainty regarding the long-term clinical significance of vesicoureteral reflux and urinary tract infection–related renal scarring.

No ideal diagnostic algorithm exists. We found marked variability in sensitivity and specificity for detection of abnormalities using current protocols. We also highlight the considerable cost differences, both financially and in terms of radiation dose, of different protocols. (Read the full article)

Computed tomography is commonly used for neuroimaging in newborn infants with neonatal encephalopathy despite concerns over potential harm from radiation exposure. Alternative neuroimaging options include MRI and cranial ultrasound.

Using a very large, international, multicenter database, we demonstrate utilization rates and compare diagnostic findings of computed tomography, MRI, and cranial ultrasound in the evaluation of neonatal encephalopathy. (Read the full article)

Professional organizations recommend ultrasound as the initial diagnostic imaging modality for children with suspected nephrolithiasis. Computed tomography utilization for children with nephrolithiasis treated at freestanding children’s hospitals is common and varies substantially by hospital.

The high prevalence and regional variability of CT as the first imaging study for children with nephrolithiasis who presented to emergency departments, outpatient clinics, and hospitals throughout the United States indicate that current imaging practices deviate substantially from guidelines.

Perinatal complications predict increased risk for morbidity and early mortality. Evidence of perinatal programming of adult mortality raises the question of what mechanisms embed this long-term effect. Telomere length and perceived facial age are 2 indicators of accelerated aging.

Perinatal complications predicted greater signs of accelerated aging "inside," as measured objectively by leukocyte telomere length, an indicator of cellular aging, and "outside," as measured subjectively by perceived age, an indicator of declining integrity of tissues. (Read the full article)

White matter abnormality (WMA) on neuroimaging is considered a crucial link with adverse neurodevelopmental outcome in preterm infants. Brain MRI is more sensitive in detecting WMA than cranial ultrasound (CUS), but questions remain about timing and prognostic value of modalities.

Near-term CUS and MRI abnormalities were associated with adverse 18- to 22-month outcomes, independent of early CUS and other factors, underscoring the relative prognostic value of later neuroimaging in this large, extremely preterm cohort surviving to near-term. (Read the full article)

Concern of the risk of malignancy from ionizing radiation has prompted many to advocate for judicious use of computed tomography (CT) and as low as necessary radiation doses administered per scan. Recent analysis has shown a decline in CT utilization.

We identified decreases in CT utilization between 2004 and 2012 for the 10 most common diagnostic groups receiving CT. Decreases were typically associated with increases in alternate imaging modalities. We provide a possible reason for the decrease in CT utilization. (Read the full article)

Adolescent vaccination rates lag behind other childhood vaccines. Text messaging to improve uptake of adolescent vaccines has been shown to be effective in academic centers but has not been studied in other settings.

This study, done in 5 private and 2 safety-net practices, used a bidirectional text message as a behavioral prompt and showed text messaging was effective at increasing uptake of all adolescent vaccines. Costs were similar to other reminder/recall methods. (Read the full article)
