Adjusting for switches to multiple treatments: Should switches be handled separately or combined?

Treatment switching is common in randomised controlled trials (RCTs). Participants may switch onto a variety of different treatments, all of which may have different treatment effects. Adjustment analyses that target hypothetical estimands - estimating outcomes that would have been observed in the absence of treatment switching - have focused primarily on a single type of switch.

Diversity of lake bacteria promotes human echovirus inactivation.

Human enteric viruses can remain infective in surface waters for extended periods of time, posing a public health risk. Microbial activity contributes to the inactivation of waterborne enteric viruses, but while individual bacteria-virus interactions have been characterized, the importance of microbial diversity remains unknown. Here, we experimentally manipulated the diversity of bacterial communities from Lake Geneva across three seasons using a dilution-to-extinction approach and monitored the inactivation and genome decay of echovirus 11, a member of the genus.

Global increase in the occurrence and impact of multiyear droughts.

Persistent multiyear drought (MYD) events pose a growing threat to nature and humans in a changing climate. We identified and inventoried global MYDs by detecting spatiotemporally contiguous climatic anomalies, showing that MYDs have become drier, hotter, and led to increasingly diminished vegetation greenness. The global terrestrial land affected by MYDs has increased at a rate of 49,279 ± 14,771 square kilometers per year from 1980 to 2018.

at Sterkfontein did not consume substantial mammalian meat.

Incorporation of animal-based foods into early hominin diets has been hypothesized to be a major catalyst of many important evolutionary events, including brain expansion. However, direct evidence of the onset and evolution of animal resource consumption in hominins remains elusive. The nitrogen-15 to nitrogen-14 ratio of collagen provides trophic information about individuals in modern and geologically recent ecosystems (<200,000 years ago), but diagenetic loss of this organic matter precludes studies of greater age.

Don't pretend COVID-19 didn't happen.

Just over 5 years ago, on New Year's Eve 2019, the World Health Organization (WHO) became aware of the first cases of pneumonia of unknown etiology in Wuhan, China. A massive global infectious disease storm was already brewing-one that would shut down the world, with profound economic, social, and political impacts that still reverberate today. It's understandable that governments and individuals may want to forget that the COVID-19 pandemic ever happened, but such collective amnesia prevents humanity from being ready for the next pandemic.

Drought in a warmer, CO-rich climate restricts grassland water use and soil water mixing.

Soil water sustains terrestrial life, yet its fate is uncertain under a changing climate. We conducted a deuterium labeling experiment to determine whether elevated atmospheric carbon dioxide (CO), warming, and drought impact soil water storage and transport in a temperate grassland. Elevated CO created a wetter rootzone compared with ambient conditions, whereas warming decreased soil moisture.

Neuronal-ILC2 interactions regulate pancreatic glucagon and glucose homeostasis.

The immune system shapes body metabolism, while interactions between peripheral neurons and immune cells control tissue homeostasis and immunity. However, whether peripheral neuroimmune interactions orchestrate endocrine system functions remains unexplored. After fasting, mice lacking type 2 innate lymphoid cells (ILC2s) displayed disrupted glucose homeostasis, impaired pancreatic glucagon secretion, and inefficient hepatic gluconeogenesis.

Pressure Protein Denaturation Compared to Thermal and Chemical Unfolding: Analyses with Cooperative Models.

The thermodynamics of pressure-induced protein denaturation could so far not be directly compared with protein denaturation induced by temperature or chemical agents. Here, we provide a new cooperative model for pressure-induced protein denaturation that allows the quantitative comparison of all three denaturing processes based on their free energy, enthalpy, entropy, and cooperativity. As model proteins, we use apolipoprotein A-1 and lysozyme.

Probing the Photochemical Formation of Hydroxyl Radical from Dissolved Organic Matter: Insights into the HO-Dependent Pathway.

This study quantifies the contribution of the HO-dependent pathway to hydroxyl radical (OH) production from the photolysis of dissolved organic matter (DOM). OH formation rates were cross-validated using benzoate and terephthalate as probe compounds for diverse DOM sources (reference isolates and whole waters). Catalase addition revealed that the HO-dependent pathway accounts for 10-20% of the total OH production in DOM isolate materials, but no significant correlation was observed between ambient iron (Fe) concentrations and HO-dependent OH formation.

App-Based Coaching to Prevent Addictive Behaviors in Vocational School Students: A Cluster Randomized Trial.

Purpose: This two-arm cluster randomized controlled trial evaluated the effectiveness of an app-based addiction prevention program in German vocational school students.

Methods: Schools from 5 German federal states were recruited. No eligibility criteria for classes were applied; enrollment decisions were made by school heads or teachers.

ESMO Global Consortium Study on the availability, out-of-pocket costs, and accessibility of cancer medicines: 2023 update.

Background: The availability and affordability of safe, effective cancer therapies are core requirements for effective cancer control. Global disparities exist in access, however, yielding unequal cancer outcomes. The goal of this study was to provide updated data regarding the formulary availability, out-of-pocket costs, and accessibility of cancer medicines in countries across the full spectrum of economic development areas.

Anatomical study of the posterior talofibular ligament: A descriptive analysis of its dual-bundle structure.

Background: The lateral ankle ligament complex, consisting of the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL), is essential for ankle stability. While the ATFL and CFL are frequently studied, the PTFL's role remains less explored.

Methods: Twelve fresh-frozen ankle specimens were dissected to analyze the PTFL's origin, trajectory, and talar insertion, focusing on its bundles and anatomical relationships.

Bacillary layer detachment: Updates on its clinical and prognostic significance in retinal disease.

Bacillary layer detachment (BALAD) refers to the distinctive splitting at the level of the photoreceptor inner segment myoid and accumulation of intraretinal fluid, as seen on optical coherence tomography (OCT).BALAD is an increasingly recognized OCT biomarker of numerous heterogeneous chorioretinal diseases, including posterior uveitis, age-related macular degeneration and macular neovascularization, neoplastic and paraneoplastic retinal disorders, rhegmatogenous retinal detachment, blunt ocular trauma, and miscellaneous conditions. The recognition of BALAD is clinically relevant because, based on the specific etiology, BALAD may require simple observation, ocular or systemic medical treatment, or even surgical intervention, with subsequent different prognosis.

Minimally Invasive Glass-Ceramic Restorations: Clinical and Patient-Reported Outcomes in Full-Mouth Rehabilitations.

Objectives: To evaluate clinical outcomes (restoration survival, technical and biological complications), and patient-reported outcome measures (PROMs) of full mouth rehabilitation with minimally invasive glass-ceramic restorations after up to 12 years of clinical service.

Materials And Methods: Twenty individuals (12 females, 8 males) received full-mouth rehabilitation with minimally invasive tooth-supported glass-ceramic restorations during the years 2009 - 2017 and agreed to participate in a follow-up visit. Full dental and periodontal examinations were completed, and the restorations were evaluated according to United States Public Health Service (USPHS) criteria.

Circulating monocytes upregulate CD52 and sustain innate immune function in cirrhosis unless acute decompensation emerges.

Background & Aims: Infectious complications determine the prognosis of cirrhosis patients. Their infection susceptibility relates to the development of immuneparesis, a complex interplay of different immunosuppressive cells and soluble factors. Mechanisms underlying the dynamics of immuneparesis of innate immunity remain inconclusive.

The regulatory landscape of 5' UTRs in translational control during zebrafish embryogenesis.

The 5' UTRs of mRNAs are critical for translation regulation during development, but their in vivo regulatory features are poorly characterized. Here, we report the regulatory landscape of 5' UTRs during early zebrafish embryogenesis using a massively parallel reporter assay of 18,154 sequences coupled to polysome profiling. We found that the 5' UTR suffices to confer temporal dynamics to translation initiation and identified 86 motifs enriched in 5' UTRs with distinct ribosome recruitment capabilities.

Establishing quality assurance for COVID-19 antigen tests in the Indo Pacific Region: A multi-site implementation study.

Background: Quality assurance programs (QAPs) are used to evaluate the analytical quality of a diagnostic test and provide feedback to improve quality processes in testing. Rapid diagnostic tests were used in both laboratory and non-laboratory settings to diagnose COVID-19, although varied in reported performance. We aimed to design and implement a QAP for antigen rapid diagnostic tests (Ag-RDTs) for COVID-19 in Cambodia, Lao PDR, and Papua New Guinea.

Effects of warning information at medication initiation on deprescribing intentions in older adults: A hypothetical vignette.

Objectives: To explore to what degree providing patients warning information about the long-term risks of a medication would affect their subsequent desire to discontinue it.

Methods: We conducted a vignette-based online experiment in which participants aged ≥ 65 years from the United States were asked to imagine starting and subsequently stopping omeprazole. Participants were randomized to one of four vignettes about starting omeprazole (potential long-term harms or no harm information; OTC vs.

YAP promotes fibrosis by regulating macrophage to myofibroblast transdifferentiation and M2 polarization in chronic pancreatitis.

Chronic pancreatitis (CP) is a clinical entity characterized by progressive inflammation and irreversible fibrosis of the pancreas, which ultimately leads to exocrine and/or endocrine insufficiency as well as an increased risk of pancreatic cancer. Currently, there are no specific or effective approved therapies for CP. Herein, we show that macrophage to myofibroblast transdifferentiation (MMT) and M2 macrophage polarization are associated with both human CP and CP experimental mouse models.

Development, content validation and feasibility of a decision aid tool for the treatment of women with menopausal symptoms.

Introduction: Despite research supporting menopause hormonal therapy for menopausal women, its use continues to decline in most European countries and the United States. Experts highlighted the need for global assessment tools to assist clinicians in evaluating treatment for symptomatic menopausal women, which led to the development of the Menopause Treatment Tool, with separate versions for women and healthcare professionals. Both versions of the tool focus on menopausal symptoms, risk levels and suggested actions; the women's tool is administered prior to the consultation, while the clinician tool is administered by the clinician during the clinical consultation.

CD-44 targeted nanoparticles for combination therapy in an in vitro model of triple-negative breast cancer: Targeting the tumour inside out.

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer defined by the lack of three key receptors: estrogen, progesterone, and HER2. This lack of receptors makes TNBC difficult to treat with hormone therapy or drugs, and so it is characterised by a poor prognosis compared to other kinds of breast cancer. This study explores photoactive Poly(lactic-co-glycolic acid) (PLGA) nanoparticles as a potential therapeutic strategy for TNBC.
