Laser spectroscopy of atomic hydrogen and hydrogen-like atoms is a powerful tool for tests of fundamental physics. The 1-2 transition of hydrogen in particular is a cornerstone for stringent Quantum Electrodynamics (QED) tests and for an accurate determination of the Rydberg constant. We report laser excitation of the 1-2 transition in singly-ionized helium (He), a hydrogen-like ion with much higher sensitivity to QED than hydrogen itself.

Introduction: Congenital and acquired damage to hypothalamic nuclei or neuronal circuits controlling satiety and energy expenditure results in hypothalamic obesity (HO). To date, successful weight loss and satiety has only been achieved in a limited number of affected patients across multiple drug trials. Glucagon-like peptide-1 (GLP-1) acts via central pathways that are independent from the hypothalamus to induce satiety.

We present a Bayesian inference-based nonlinear least-squares fitting approach developed to reliably fit challenging, noisy data in an automated and robust manner. The advantages of using Bayesian inference for nonlinear fitting are demonstrated by applying this approach to a set of temperature-dependent film thickness () data collected by ellipsometry for thin films of polystyrene (PS) and poly(2-vinylpyridine) (P2VP). The glass transition experimentally presents as a continuous transition in thickness characterized by a change in slope that in thin films with broadened transitions can become particularly subtle and challenging to fit.

Background: Treatment of pediatric craniopharyngioma requires a multidisciplinary approach to counsel patients and families on the spectrum of treatment options, including biopsy, radiation, and/or resection. Gross-total resection can avoid radiation and its long-term comorbidities. In very young patients, this is of particular importance but is especially challenging because of anatomical considerations.

Article Synopsis
  • This study explores the link between ABO blood groups and the risk of early stent thrombosis in patients who underwent coronary interventions, focusing particularly on non-O blood groups and their association with cardiovascular issues.
  • Among 10,714 patients, only 0.73% experienced early stent thrombosis, and while non-O blood groups weren't significantly linked, those with B-antigens (B and AB blood types) showed a higher risk for early thrombosis compared to O type.
  • The findings suggest that B-antigen presence is a notable factor in early stent thrombosis risk, indicating a need for more research to understand the biological mechanisms behind this relationship.

Naturally occurring cellulose Iβ with its characteristic parallel orientation of cellulose chains is less stable than cellulose II, in which neighboring pairs of chains are oriented antiparallel to each other. While the distinct hydrogen-bond patterns of these two cellulose crystal forms are well established, the energetic role of the hydrogen bonds for crystal stability, in comparison to the van der Waals (vdW) and overall electrostatic interactions in the crystals, is a matter of current debate. In this article, we investigate the relative stability of celluloses Iβ and II in energy minimizations with classical force fields.

Background: The large-scale proteomic platform known as the SomaScan® assay is capable of simultaneously measuring thousands of proteins in patient specimens through next-generation aptamer-based multiplexed technology. While previous studies have utilized patient peripheral blood to suggest serum biomarkers of prognostic or diagnostic value in osteosarcoma (OSA), the most common primary pediatric bone cancer, they have ultimately been limited in the robustness of their analyses. We propose utilizing this aptamer-based technology to describe the systemic proteomic milieu in patients diagnosed with this disease.

Article Synopsis
  • - The COVID-19 pandemic severely impacted individuals with opioid use disorder (OUD), leading to fewer emergency and hospital visits but a rise in fatal overdoses among veterans.
  • - A study compared veterans with OUD before and after the pandemic, finding significant decreases in emergency and inpatient care usage, as well as fewer recorded non-fatal overdoses during the pandemic.
  • - Despite the drop in non-fatal overdoses, the data indicated an increase in fatal overdoses, suggesting that healthcare access disruptions during the pandemic may have hidden the actual risks and needs for treatment among this population.

Article Synopsis
  • The study addresses the lack of resources for medical students focusing on social determinants of health (SDH) in pediatrics by developing a case-based curriculum for third-year medical students during their pediatric clerkship.
  • The curriculum consisted of four brief educational segments and was evaluated through voluntary pre- and post-surveys assessing knowledge, skills, and case analysis related to SDH.
  • Results showed significant improvements in students' understanding of SDH and their ability to formulate relevant questions regarding the impact of these determinants on pediatric patients' health.

Network analysis is often enriched by including an examination of node metadata. In the context of understanding the mesoscale of networks it is often assumed that node groups based on metadata and node groups based on connectivity patterns are intrinsically linked. This assumption is increasingly being challenged, whereby metadata might be entirely unrelated to structure or, similarly, multiple sets of metadata might be relevant to the structure of a network in different ways.

Office-based testing, enhanced by advances in imaging technology, is routinely used in eye care to non-invasively assess ocular structure and function. This type of imaging coupled with autonomous artificial intelligence holds immense opportunity to diagnose eye diseases quickly. Despite the wide availability and use of ocular imaging, there are several factors that hinder optimization of clinical practice and patient care.

Unlabelled: Millions of Americans suffering from Opioid Use Disorders (OUD) face a high risk of fatal overdose due to opioid-induced respiratory depression (OIRD). Fentanyl, a powerful synthetic opioid, is a major contributor to the rising rates of overdose deaths. Reversing fentanyl-induced respiratory depression has proved to be challenging due to both its high potency and lipophilicity.

This article elaborates research participant perspectives on the communication of individual research results from genomic analyses. While most analyses focus on how to communicate results from the perspectives of clinicians or researchers, there is insufficient data on user perspectives and how this information may be used, valued, and interpreted by patients and their families. The concept of personal utility, which considers factors related to quality of life, including on how information may impact the person's future decisions, has been shown to be particularly relevant to understand research participant perspectives and to move beyond clinical and analytic utility factors such as mortality and morbidity.

Short Tandem Repeats (STRs) are the most widespread markers in forensic genetics. However, STR stutter peaks can mask alleles from a minor contributor when analysing mixtures, hindering the interpretation of complex profiles. In this study we compared the performance of a previously described panel of microhaplotypes (MHs), an alternative type of forensic marker, against a standard STR kit.

Millions of people have been displaced within or outside their countries. Disruptions associated with displacement often lead to transactional sex with dire social, sexual and reproductive health implications. A common driver of transactional sex is food insecurity among refugees and internally displaced persons (IDPs), yet IDP/refugee settings offer an opportunity for females to challenge and renegotiate gender norms and exercise greater control over their lives and sexuality.

Article Synopsis
  • The study investigates the effects of maternal vitamin D and omega-3 fatty acid (DHA) deficiencies on neurodevelopmental traits in offspring, using a method called Mendelian randomization to establish causal relationships rather than just correlations.
  • Results showed that while higher maternal vitamin-D levels were initially linked to lower ADHD traits in children, this association disappeared when controlling for genetic factors, indicating no causal maternal influence.
  • The findings suggest that prior observational studies might have been misleading due to genetic confounding, and that genetic predispositions for autism and ADHD are related to lower levels of vitamin D and DHA in mothers.

Background: Geriatric rehabilitation aims at increasing physical and social activity and maintaining the functional reserve of older people. However, the continuity of geriatric rehabilitation in the outpatient setting is limited due to a lack of structured aftercare programs. In order to overcome this, a three-month multimodal home-based intervention program (GeRas) was implemented.
