OBJECTIVE: The aim was to review and analyse the literature on clinical outcomes of drug coated balloon (DCB) vs. standard percutaneous transluminal angioplasty (PTA) for the treatment of infrapopliteal arterial disease. METHODS: This is a systematic review and meta-analysis. The MEDLINE, EMBASE and Cochrane Database…

BACKGROUND: Conducting a systematic review requires a comprehensive bibliographic search. Comparing different search strategies is essential for choosing those that cover all useful data sources. Our aim was to develop search strategies for article retrieval for a systematic review of the global epidemiology of kidney…

BACKGROUND: Wearable technologies provide users hands-free access to computer functions and are becoming increasingly popular on both the consumer market and in various industries. The medical industry has pioneered research and implementation of head-mounted wearable devices, such as Google Glass. Most of this researc…

BACKGROUND: Mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase responsible for regulating ribosomal biogenesis and protein synthesis. Dysregulation of mTOR contributes to tumorigenesis, angiogenesis, cellular growth and metastasis but its roles in esophageal squamous cell carcinoma (ESCC) are con…

Vascular endothelial growth factor (VEGF) expression is upregulated by hypoxia-inducible factor-1 (HIF-1) in ischemic tissues and growing tumors. Normally, HIF-1 activity depends on the amount of HIF-1alpha subunit, which is tightly regulated by the oxygen tension. In the myocardium, VEGF expression has been shown to b…

PURPOSE: Pediatric brain tumors, including high-grade gliomas (HHG), medulloblastomas (MB), and ependymomas (EPN), are a leading cause of death in children. They are often immunologically "cold" with low tumor mutational burden (TMB) and very few tumor-infiltrating lymphocytes (TILs), which may limit the role of immune…

BACKGROUND: The optimal sequencing of surgery and chemotherapy in advanced epithelial ovarian cancer remains debated. While primary debulking surgery (PDS) has been considered the standard approach, recent randomized trials have questioned its survival advantage over neoadjuvant chemotherapy (NACT) followed by interval…

BACKGROUND: Postmortem magnetic resonance imaging (PMMRI) following fetal and perinatal demise is increasingly used in clinical practice as a non-invasive adjunct or alternative to autopsy. Imaging protocols vary widely between centers and there is currently no consensus. OBJECTIVE: From expert consensus, we aimed to…

A COMMENTARY ON: Silva E J N L D, Pinto K P, Riche F N S J et al. Success of primary teeth pulpotomy using calcium silicate cements: a systematic review and meta-analysis of randomised clinical trials. Pediatr Dent 2024; 46: 373-395. INTRODUCTION: This systematic review and meta-analysis of randomised clinical trials…

BACKGROUND: Metal oxide nanoparticle-reinforced polymethyl methacrylate (PMMA) has been shown to improve mechanical properties, such as strength. Different types of metal oxide nanoparticles have been used previously, but the comparative effect on the strength of heat-cured denture base resins remains unclear. OBJECTI…

Lower limb muscle dysfunction is a key driver for impaired physical capacity and frailty status, both characteristics of sarcopenia. Sarcopenia is the key pathway between frailty and disability. Identifying biological markers for early diagnosis, treatment, and prevention may be key to early intervention and prevention…

CONTEXT: Polycystic ovary syndrome (PCOS) is a highly heritable disease. Emerging evidence elucidated the elevated prevalence of reproductive abnormalities in first-degree relatives (FDRs) of patients with PCOS. OBJECTIVE: To explore the reproductive health in FDRs of patients with PCOS. METHODS: Ten databases were s…

BACKGROUND: Chromosomal mosaicism can be detected in different stages of early life: in cleavage stage embryos, in blastocysts and biopsied cells from blastocysts during preimplantation genetic testing for aneuploidies (PGT-A) and later during prenatal testing, as well as after birth in cord blood. Mosaicism at all dif…

BACKGROUND: The pathogenesis of diabetic peripheral neuropathy is more complex and it is not yet clear, but studies have shown that microangiopathy and oxidative stress responses are closely related to their pathogenesis. At present, the treatment of improving microcirculation and antioxidant stress is mainly used in c…

INTRODUCTION: Whether combining Chinese herbal medicines (CHMs) and chemotherapy to treat patients with advanced non-small-cell lung cancer (NSCLC) has clinical benefits has yet to be confirmed. A meta-analysis was performed to address the efficacy of CHM in patients with advanced NSCLC. METHODS: Seven databases, incl…

BACKGROUND: Research needs to be undertaken rapidly in the event of an influenza pandemic to develop and evaluate triage methods for people presenting to the emergency department with suspected pandemic influenza. OBJECTIVES: We aimed to pilot a research study to be undertaken in a pandemic to identify the most accura…

BACKGROUND: Distance running continues to experience increased participation in the Western world, although it is associated with high injury rates. Barefoot running has been increasingly proposed as a means to prevent overuse injury due to various biomechanical differences, including reduced joint loading rates and al…

BACKGROUND: Efforts to assure high-quality, safe, clinical care depend upon capturing information about near-miss and adverse outcome events. Inconsistent or unreliable information capture, especially for infrequent events, compromises attempts to analyze events in quantitative terms, understand their implications, and…

BACKGROUND: Theophylline and long acting beta-2 agonists are bronchodilators used for the management of persistent asthma symptoms, especially nocturnal asthma. They represent different classes of drug with differing side-effect profiles. OBJECTIVES: To assess the comparative efficacy, safety and side-effects of long-…

The beginning of the 1980s saw the birth of Zimbabwe as a result of a protracted liberation war. It coincided with global interest in primary health care, the concept of universal primary school education and, unfortunately, moves towards economic stabilization and structural adjustment programmes. Economic structural…
