Triggering final follicular maturation for IVF cycles.

As part of a conventional controlled ovarian hyperstimulation (COH) regimen, final follicular maturation is usually triggered by a single bolus dose of human chorionic gonadotropin (hCG). COH, which combines GnRH antagonist co-treatment with GnRH agonist(GnRHa) trigger, is often used in attempts to eliminate severe early ovarian hyperstimulation syndrome and to improve oocyte/embryo yield and quality. Recently, the combination of GnRHa, with hCG trigger has also been implemented into clinical practice.

Death risk prediction model for patients with non-traumatic intracerebral hemorrhage.

Background: This study aimed to assess the risk of death from non-traumatic intracerebral hemorrhage (ICH) using a machine learning model.

Methods: 1274 ICH patients who met the specified inclusion and exclusion criteria were analyzed retrospectively in the MIMIC IV 3.0 database.

The effect of azithromycin treatment on respiratory morbidity in children with down syndrome.

Background: Children with Down syndrome (DS) often experience recurrent and prolonged hospitalizations from respiratory infections. While Azithromycin has been increasingly used for lower-respiratory tract infections (LRTIs) in children, its potential benefits for DS patients are unexplored. This study evaluates the effect of chronic azithromycin treatment on respiratory morbidity in children with DS.

Continuing bonds and the posthumous child.

The strategies that bereaved individuals use to establish an ongoing bond with the deceased have attracted considerable attention. However, the narratives of young widows pregnant at the time of their partner's death reveal unique strategies that have not yet received attention in the literature. This interpretive phenomenological research explores the strategies employed by 13 Israeli widows who lost their partners while pregnant.

When We Make Errors and Do Harm: A Narrative Review of Second Victim Syndrome and Implications for Neuro-Ophthalmologists.

Background: In the aftermath of an adverse event, the first priority is to provide care for the patient, known as the first victim. However, the experiences of healthcare professionals (HCPs) involved in these events, known as "second victims", have been largely overlooked. This review aims to consolidate existing knowledge on second victim syndrome (SVS), explore its unique implications for neuro-ophthalmologists, and suggest support strategies to increase awareness and meet the needs of affected colleagues.

Microglia modulate the cerebrovascular reactivity through ectonucleotidase CD39.

Microglia and the border-associated macrophages contribute to the modulation of cerebral blood flow, but the mechanisms have remained uncertain. Here, we show that microglia regulate the cerebral blood flow baseline and the responses to whisker stimulation or intra-cisternal magna injection of adenosine triphosphate, but not intra-cisternal magna injection of adenosine in mice model. Notably, microglia repopulation corrects these cerebral blood flow anomalies.

Dynamically induced spatial segregation in multispecies bacterial bioconvection.

Active matter, from motile bacteria to animals, can exhibit striking collective and coherent behavior. Despite significant advances in understanding the behavior of homogeneous systems, little is known about the self-organization and dynamics of heterogeneous active matter, such as complex and diverse bacterial communities. Under oxygen gradients, many bacterial species swim towards air-liquid interfaces in auto-organized, directional bioconvective flows, whose spatial scales exceed the cell size by orders of magnitude.

The Future of Microbiome Therapeutics.

The human microbiome exerts profound influence over various biological processes within the body. Unlike many host determinants, it represents a readily accessible target for manipulation to promote health benefits. However, existing commercial microbiome-directed products often exhibit low efficacy.

Mapping cells through time and space with moscot.

Single-cell genomic technologies enable the multimodal profiling of millions of cells across temporal and spatial dimensions. However, experimental limitations hinder the comprehensive measurement of cells under native temporal dynamics and in their native spatial tissue niche. Optimal transport has emerged as a powerful tool to address these constraints and has facilitated the recovery of the original cellular context.

CD45-PET is a robust, non-invasive tool for imaging inflammation.

Imaging inflammation holds immense potential for advancing the diagnosis, treatment and prognosis of many conditions. The lack of a specific and sensitive positron emission tomography (PET) probe to detect inflammation is a critical challenge. To bridge this gap, we present CD45-PET imaging, which detects inflammation with exceptional sensitivity and clarity in several preclinical models.

Novel Objective Tool to Assess Tremor Reveals Unilateral Focused Ultrasound Improves Tremor Bilaterally.

Background: Tremor in essential tremor and in tremor-dominant Parkinson's disease is assessed by subjective observations in patients undergoing focused ultrasound thalamotomy, a minimally invasive procedure intended to alleviate tremor in these patients.

Objective: To develop an objective tool for tremor analysis to be used before and after focused ultrasound thalamotomy treatment in the treated hand (contralateral to ablation) and non-treated (ipsilateral to ablation).

Methods: Using image processing and signal processing that utilized images of a Archimedes spiral drawing, we created a tool to analyze tremor.

Evaluating pulmonary stenosis and regurgitation impact on cardiac strain and strain rate in a porcine model via magnetic resonance feature tracking.

Background: Pulmonary stenosis (PS) is common in congenital heart disease and an integral finding in Tetralogy of Fallot (TOF). Pulmonary regurgitation (PR) is more commonly found following surgery in repaired TOF. We aimed to evaluate the haemodynamic effects of PS and PR on cardiac physiology in a porcine model using cardiac magnetic resonance-based feature tracking (CMR-FT) deformation imaging.

Diversity in the medical research ecosystem: a descriptive scientometric analysis of over 49 000 studies and 150 000 authors published in high-impact medical journals between 2007 and 2022.

Objectives: Health research that significantly impacts global clinical practice and policy is often published in high-impact factor (IF) medical journals. These outlets play a pivotal role in the worldwide dissemination of novel medical knowledge. However, researchers identifying as women and those affiliated with institutions in low- and middle-income countries (LMICs) have been largely under-represented in high-IF journals across multiple fields of medicine.

Pericardial effusion cytology: malignancy rates, patterns of metastasis, comparison with pericardial window, and genomic correlates.

Introduction: Cytologic evaluation of pericardial fluid is essential for diagnosing malignant pericardial effusions secondary to metastatic disease and for guiding appropriate clinical management; however, large cohort and up-to-date studies on malignancy rates and distribution of primary tumor sites is lacking.

Materials And Methods: A retrospective analysis of pericardial fluid specimens from 2 large academic medical centers over a 10-year period was conducted. Clinical and specimen characteristics were correlated with cytologic diagnoses, and compared with surgical pathology pericardial specimens when available.

'Occupational experience' in occupational therapy and occupational science literature: A scoping review.

Introduction: 'Occupational experience' (OE) is widely used within the occupational therapy profession. However, it lacks a clear and unified definition in the profession's consensus practice frameworks and seminal models. Therefore, this study aimed to examine how OE has been defined and described in both occupational therapy and occupational science literature.

Harnessing the power of human breast milk to boost intestinal permeability for nanoparticles and macromolecules.

The intricate interplay between human breast milk, nanoparticles, and macromolecules holds promise for innovative nutritional delivery strategies. Compared to bovine milk and infant formula, this study explores human breast milk's role in modulating intestinal permeability and its impact on nanoparticle and macromolecule transport. Comparative analysis with bovine milk and infant formula reveals significant elevations in permeability with human breast milk, accompanied by a decrease in transepithelial electrical resistance, suggesting enhanced paracellular transport.
