The experimental methods employed during metagenomic sequencing analyses of microbiome samples significantly impact the resulting data and typically vary substantially between laboratories. In this study, a full factorial experimental design was used to compare the effects of a select set of methodological choices (sample, operator, lot, extraction kit, variable region, and reference database) on the analysis of biologically diverse stool samples. For each parameter investigated, a main effect was calculated that allowed direct comparison both between methodological choices (bias effects) and between samples (real biological differences).

BMJ Open

December 2024

Research and Development Center for New Medical Frontiers, Department of Advanced Medicine, Division of Neonatal Intensive Care Medicine, Kitasato University School of Medicine, Sagamihara, Kanagawa, Japan.

Objectives: Inhaled nitric oxide (iNO) is a known treatment for pulmonary hypertension (PH) associated with bronchopulmonary dysplasia in preterm infants after 7 days of age (postacute phase). However, a consensus regarding the optimal criteria for initiating iNO therapy in this population in the postacute phase is currently lacking. This study, therefore, aimed to identify the criteria for initiating iNO therapy, alongside the associated clinical and echocardiographic findings, in this population.

Introduction: Early lung cancer screening (LCS) through low-dose CT (LDCT) is crucial but underused due to various barriers, including incomplete or inaccurate patient smoking data in the electronic health record and limited time for shared decision-making. The objective of this trial is to investigate a patient-centred intervention, MyLungHealth, delivered through the patient portal. The intervention is designed to improve LCS rates through increased identification of eligible patients and informed decision-making.

Introduction: End-of-life care is essential for older adults aged ≥60, particularly those residing in long-term care facilities, such as nursing homes, which are known for their home-like environments compared with hospitals. Due to potential limitations in medical resources, collaboration with external healthcare providers is crucial to ensure comprehensive services within these settings. Previous studies have primarily focused on team-based models for end-of-life care in hospitals and home-based settings.

Ruthenium (Ru)-based electrocatalysts have shown promise for anion exchange membrane water electrolysis (AEMWE) due to their ability to facilitate water dissociation in the hydrogen evolution reaction (HER). However, their performance is limited by strong hydrogen binding, which hinders hydrogen desorption and water re-adsorption. This study reports the development of RuNi nanoalloys supported on MoO, which optimize the hydrogen binding strength at Ru sites through modulation by adjacent Ni atoms.

While gas chromatography mass spectrometry (GC-MS) has long been used to identify compounds in complex mixtures, this process is often subjective and time-consuming and leaves a large fraction of seemingly good-quality spectra unidentified. In this work, we describe a set of new mass spectral library-based methods to assist compound identification in complex mixtures. These methods employ mass spectral uniqueness and compound ubiquity of library entries alongside noise reduction and automated comparison of retention indices to library compounds.

Background: In Cameroon, like in many other resource-limited countries, data generated by health settings including morbidity and mortality parameters are not always uniform. In the absence of a national guideline necessary for the standardization and harmonization of data, precision of data required for effective decision-making is therefore not guaranteed. The objective of the present study was to assess the reporting style of morbidity and mortality data in healthcare settings.

Determining timeframes to death for imminently dying patients: a retrospective cohort study.

BMC Palliat Care

January 2025

Caring Futures Institute, Flinders University, Sturt Rd, Bedford Park, Adelaide, South Australia, 5042, Australia.

Background: Clinicians are frequently asked 'how long' questions at end-of-life by patients and those important to them, yet predicting timeframes to death remains uncertain, even in the last weeks and days of life. Patients and families wish to know so they can ask questions, plan, make decisions, have time to visit and say their goodbyes, and have holistic care needs met. Consequently, this necessitates a more accurate assessment of empirical data to better inform prognostication and reduce uncertainty around time until death.

Sichuan Provincial Engineering Research Center of Formation Principle and Quality Evaluation of Genuine Medicinal Materials, Sichuan Engineering Technology Research Center of Genuine Regional Drug, Translational Chinese Medicine Key Laboratory of Sichuan Province, Key Laboratory of Biological Evaluation of TCM Quality of the State Administration of Traditional Chinese Medicine, Sichuan Institute for Translational Chinese Medicine Chengdu 610041, China.

Traditional Chinese medicine(TCM) resources refer to the total reserves of plants, animals, and minerals that can be used as raw materials of TCM(including Chinese medicial materials, TCM decoction pieces, TCM dispensing granules, traditional Chinese patent medicine, and TCM hospital preparation) and folk herbal medicine, which served as the material basis of inheritance, innovation, and development of TCM. In recent years, the sustainable utilization of TCM resources has received high attention and acquired a series of significant achievements in resource survey, quality evaluation, resource protection, innovative technology, and development and utilization, which effectively promoted the sustainable utilization of TCM resources and high-quality development of the TCM industry. The most urgent issue currently is to shift the focus of the research on the sustainable utilization of TCM resources from a sustainable utilization technology system to a sustainable utilization evaluation indicator system.
