BACKGROUND: Reelin plays an important role in the regulation of synaptic plasticity in adulthood. Administration of 5-metoxytryptamine (5MT), an agonist of serotonin receptors, during natal and neonatal periods results in decreased reelin expression. In adulthood, reelin is expressed by GABAergic neurons. OBJECTIVES:…

OBJECTIVE: To conduct a systematic review of evaluated treatments for recurrent abdominal pain (RAP) in children. METHODS: Online bibliographic databases were searched for the terms "recurrent abdominal pain," "functional abdominal pain," "children," or "alternative therapies" in articles classified as randomized cont…

BACKGROUND: Evidence-based public health requires that research provides policymakers with reliable and accessible information reflecting the disease threats. We described the scientific production of research in Cambodia and assessed to what extent it provides appropriate insights and implications for practice to guid…

Nitroglycerin (glyceryl trinitrate, GTN) relaxes blood vessels primarily via activation of the soluble guanylyl cyclase (sGC)/cGMP/cGMP-dependent protein kinase (cGK-I) pathway. Although the precise mechanism of sGC activation by GTN in the vascular wall is unknown, the mediatory role of nitric oxide (NO) has been post…

WHAT IS KNOWN ON THE SUBJECT?: Negative attitudes towards mental illness lead to the formation of stigma. Stigma prevents the recovery of people diagnosed with mental illness. There is evidence of stigmatic attitudes towards mental ill health among mental health professionals. Anti-stigma initiatives, such as education…

IMPORTANCE: Immune checkpoint inhibitors (ICIs) have yielded conflicting results in hepatocellular carcinoma (HCC). The overall effect of ICIs compared with standard therapies in unresectable HCC requires more research. OBJECTIVE: To estimate the efficacy and safety associated with ICIs compared with standard therapie…

INTRODUCTION: Immune checkpoint inhibitors (ICI) have transformed the treatment landscape for triple-negative breast cancer (TNBC), but their efficacy in older adults remains unclear. The objective of this systematic review is to evaluate the efficacy of ICI in patients with TNBC aged ≥65 years. MATERIALS…

BACKGROUND: Smoke-free policies in outdoor areas and semi-private and private places (eg, cars) might reduce the health harms caused by tobacco smoke exposure (TSE). We aimed to investigate the effect of smoke-free policies covering outdoor areas or semi-private and private places on TSE and respiratory health in child…

BACKGROUND: Older individuals present reductions in muscle mass and physical function, as well as a blunted muscle protein synthesis response to amino acid administration and physical activity. Although resistance training is an effective intervention to slow down muscle impairments in the elderly, there is no consensu…

BACKGROUND: Recent trials suggest improved response rates for purine analogues compared to alkylator-based regimens in the treatment of B-CLL. However, none was able to show a survival advantage. Thus, a systematic Cochrane review may be able to further define the role of purine analogues in the first-line treatment of…

Breast cancer (BC) is the most common cancer in women. The incidence and morbidity of BC are expected to rise rapidly. The stage at which BC is diagnosed has a significant impact on clinical outcomes. When detected early, an overall 5-year survival rate of up to 90% is possible. Although numerous studies have been cond…

OBJECTIVE: Dietary triggers such as gluten and highly fermentable oligo-, di- and monosaccharides and polyols (FODMAP)-containing foods have been associated with worsening irritable bowel syndrome (IBS) symptoms. However, the true impact of dietary restriction on IBS symptoms has remained unclear. The aim of this study…

BACKGROUND: The enhanced recovery after surgery (ERAS) method has been widely used in surgery and anesthesia worldwide and has been applied to a wide range of surgical specialties, including colorectal surgery, gynecology, liver surgery, breast surgery, urology, and spinal surgery. An increasing number of studies have…

BACKGROUND: Children's hospices provide a range of services for babies, children and young people who have a life-limiting or life-threatening condition, including care after death in specialist 'cool bedrooms'. Care after death is a challenging but important element of hospice care. AIM: The aims of the study were to…

: Metabolic syndrome (MetS), defined by abdominal obesity, dysglycemia, dyslipidemia, hypertension, and insulin resistance, markedly increases the risk of type 2 diabetes mellitus and cardiovascular disease. Affecting an estimated 25-30% of the global adult population, MetS represents a major and growing public health…

THEORETICAL BACKGROUND: Psychological distress significantly contributes to impairment in endometriosis. However, patients face systemic barriers to psychological support, including long waiting times, stigma, and a lack of endometriosis-specific expertise. Internet-based CBT (iCBT) offers a promising alternative, yet…

PURPOSE: Values can influence various aspects of scientific research, including research questions, methodologies, interpretations, and applications of scientific knowledge. Instead of pursuing value-free science, the scientific community recognizes the importance of value-aware science, which acknowledges the role of…

OBJECTIVE: The purpose of this research note is to share a technique for the identification of spin bias that we developed as part of a living systematic review on the cardiovascular testing of e-cigarette substitution for cigarette smoking. While some researchers have remarked on the subjective nature of ascertaining…

BACKGROUND: Little is known about how best to implement portfolio-based learning in medical school. We evaluated the introduction of a formative e-portfolio-based supervision pilot for final year medical students by seeking views of students, supervisors and graduates on use and educational effects. METHODS: Stud…

Electronic medical record (EMR) systems provide easy access to radiology reports and offer great potential to support quality improvement efforts and clinical research. Harnessing the full potential of the EMR requires scalable approaches such as natural language processing (NLP) to convert text into variables used for…
