Crystal Chemistry and Design Principles of Altermagnets.

Altermagnetism was very recently identified as a new type of magnetic phase beyond the conventional dichotomy of ferromagnetism (FM) and antiferromagnetism (AFM). Its globally compensated magnetization and directional spin polarization promise new properties such as spin-polarized conductivity, spin-transfer torque, anomalous Hall effect, tunneling, and giant magnetoresistance that are highly useful for the next-generation memory devices, magnetic detectors, and energy conversion. Though this area has been historically led by the thin-film community, the identification of altermagnetism ultimately relies on precise magnetic structure determination, which can be most efficiently done in bulk materials.

Enhancing childhood immunization coverage in Mozambique and Malawi: Study protocol of a mixed methods evaluation of the 'Let's talk about vaccines' multisite community-based participatory project.

Background: Full coverage of childhood vaccines is a persistent challenge in low- and middle-income countries, suggesting the presence of specific contextual barriers. The emergence of the COVID-19 pandemic further worsened the situation. The complementary use of community-based participatory research (CBPR) and human-centered design (HCD) approaches has the potential to effectively create tailored interventions for improving public health outcomes.

OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors.

Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. Deriving an accurate description of general quantum dynamics including memory effects is, however, a demanding task, prohibitive to standard analytical or direct numerical approaches. We present a major release of our open source software package, OQuPy (Open Quantum System in Python), which provides several recently developed numerical methods that address this challenging task.

Scrambler therapy for treatment of poststroke pain.

Objective: Strokes involving sensory pathways can result in contralesional pain syndromes often refractory to pharmacologic interventions. Scrambler therapy (ST) is a noninvasive electroanalgesia device used to treat pain caused by peripheral neuropathy; however, data are scarce regarding its use in conditions secondary to central nervous system pathology. We evaluate the efficacy of ST to treat poststroke pain.

Predominant approaches to measuring pregnancy-related anxiety in Sub-saharan Africa: a scoping review.

Background: Pregnancy-related anxiety significantly impacts maternal and fetal health in low- and middle-income countries (LMICs), including those within Sub-Saharan Africa (SSA). Most studies conducted to evaluate pregnancy-related anxiety in LMICs have utilized scales developed in high-income countries, despite significant variations in pregnancy-related anxiety due to socioeconomic and cultural contexts. This review surveyed existing literature in order to identify which scales have been used to measure pregnancy-related anxiety in SSA.

Differential expression of host oncogenes in human papillomavirus-associated nasopharyngeal and cervical epithelial cancers.

Human papillomavirus (HPV)-related cervical and nasopharyngeal cancers differ in molecular mechanisms underlying the oncogenic processes. The disparity may be attributed to differential expression of oncoproteins. The current study investigated the host oncogenes expression pattern in HPV-associated cervical and nasopharyngeal cancer.

: Hospital experiences of Ghanaian families after maternal mortalities.

Background: Rates of maternal mortality are highest in low-resource settings. Family members are often involved in the critical periods surrounding a maternal death, including transportation to health centers and financial and emotional support during hospital admissions. Maternal death has devastating impacts on surviving family members, which are often overlooked and understudied.

Evaluation and Treatment of Nausea and Vomiting in Adults.

Nausea and vomiting are common symptoms that can reduce quality of life and indicate life-threatening illness. Acute nausea and vomiting last up to 7 days. In the absence of alarm symptoms, they are typically treated symptomatically and without an extensive evaluation.

Tibetans exhibit lower hemoglobin concentration and decreased heart response to hypoxia during poikilocapnia at intermediate altitude relative to Han Chinese.

Background: High-altitude populations exhibit distinct cellular, respiratory, and cardiovascular phenotypes, some of which provide adaptive advantages to hypoxic conditions compared to populations with sea-level ancestry. Studies performed in populations with a history of high-altitude residence, such as Tibetans, support the idea that many of these phenotypes may be shaped by genomic features that have been positively selected for throughout generations. We hypothesize that such traits observed in Tibetans at high altitude also occur in Tibetans living at intermediate altitude, even in the absence of severe sustained hypoxia.

Respiratory Health Associated With Systemic Metal Exposure in Post-9/11 Veterans in the Department of Veterans Affairs Toxic Embedded Fragment Registry.

Objective: Adverse respiratory outcomes in post-9/11 veterans with elevated urinary metal measures and enrolled in the VA's Toxic Embedded Fragment registry were compared to those without elevated urinary metals.

Methods: Veterans completed questionnaires, underwent pulmonary physiology tests (pulmonary function and oscillometry), and provided urine samples for analysis of 13 metals. Respiratory symptoms, diagnoses, and physiology measures were compared in veterans with ≥1 urine metal elevation to those without metal elevations, adjusted for covariates, including smoking.

Neutrality and impartiality in Midwestern U.S. newspapers: community-oriented newspaper journalists reporting of environmental water problems in agricultural and ranching states.

Background: U.S. journalists embedded in rural and agricultural communities could adversely affect the health of residents if they avoid alerting and engaging their readers - farmers, ranchers, and community members - on environmental and health issues.

A Guiding Model for Undergraduate Medical Education Well-Being Programs.

Most medical schools have instituted undergraduate medical education (UME) well-being programs in recent years in response to high rates of medical student distress, but there is currently significant variability in the structure of UME well-being programs and limited guidance on how to best structure such programs to achieve success. In this article, the authors, all leaders of medical student well-being programs at their home institutions and members of the Association of American Medical Colleges Group on Student Affairs Committee on Student Affairs Working Group on Medical Student Well-Being between 2019 and 2023 offer guidance to the national community on how best to structure a UME well-being program. They use the current literature and their professional experiences leading well-being efforts at 7 different institutions to review the case for addressing medical student well-being, propose a guiding model, and make recommendations for strategies to implement this model.

Self-directed digital interventions for the improvement of emotion regulation-effectiveness for mental health and functioning in adolescents: protocol for a systematic review.

Introduction: Research suggests that problems with emotion regulation, that is, how a person manages and responds to an emotional experience, are related to a range of psychological disorders (eg, bipolar disorder, anxiety and depression). Interventions targeting emotion regulation have been shown to improve mental health in adults, but evidence on related interventions for adolescents is still emerging. Increasingly, self-directed digital interventions (eg, mobile apps) are being developed to target emotion regulation in this population, but questions remain about their effectiveness.

Global assessment of effective population sizes: Consistent taxonomic differences in meeting the 50/500 rule.

Effective population size (N) is a particularly useful metric for conservation as it affects genetic drift, inbreeding and adaptive potential within populations. Current guidelines recommend a minimum N of 50 and 500 to avoid short-term inbreeding and to preserve long-term adaptive potential respectively. However, the extent to which wild populations reach these thresholds globally has not been investigated, nor has the relationship between N and human activities.
