Zebrafish and other small laboratory fishes are emerging as important animal models for investigating human skeletal development and diseases. In recent years, there has been a notable increase in research publications employing x-ray radiography and micro-computed tomography to analyze the skeletal structures of these animals. However, evaluating bone morphology and mineral density in small laboratory fish poses unique challenges compared to well-established small rodent models. The varied approaches to image acquisition, analysis, and reporting across studies have led to substantial obstacles in interpreting and comparing research findings. This article addresses the urgent need for standardized reporting of parameters and methodologies related to image acquisition and analysis, as well as the adoption of harmonized nomenclature. 

Various interventions have been applied to reduce perineal trauma and obstetric anal sphincter injuries (OASIS). The efficacy of warm compresses during the second stage of labor for reducing the occurrence of perineal tears is controversial. Objective: We aimed to compare rates of spontaneous perineal tears requiring suturing, between women who received warm compresses plus perineal massage vs. perineal massage alone.

Systemic alterations in the oral cavity can be reflected in skin disorders like psoriasis. However, data about oral health factors that are affected and controlled mainly by oral microbiota in atopic dermatitis (AD) are sparse. This study compared the oral status and oral microbiota of AD patients and healthy controls.

Numerous diseases associated with COVID-19 infection and vaccination have been reported, including conditions such as the autoimmune blistering diseases (AIBD) pemphigus and pemphigoid. However, robust evidence supporting these associations is lacking. Objective: To investigate the risk of developing AIBD following COVID-19 infection and vaccination.

The aim of this study was to investigate the correlation between the thickness of meconium-stained amniotic fluid (MSAF) and maternal infectious morbidity.

The T2NOW study was a clinical trial which tested the use of two different blood sugar-reducing drugs (dapagliflozin or saxagliptin) in young people aged between 10 and 17 years with type 2 diabetes. Each drug was compared with a placebo to see to what extent the treatment can control blood sugar levels, and to observe any side effects.

Vaginal hysterectomy combined with uterosacral suspension (USLS) is a technique for treating pelvic organ prolapse. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has been described as an alternative minimal invasive approachfor treating various gynecological and non-gynecological pathologies. The aim was to compare the surgical time between conventional vaginal hysterectomy combined with USLS and vNOTES hysterectomy combined with USLS.

Safety of dupilumab in atopic dermatitis (AD) was investigated in randomized controlled trials (RCT). However, head-to-head trials comparing with conventional systemic drugs are lacking and large real-world data on the long-term safety profile as compared are scarce. Objective: To compare long-term safety profile of dupilumab with conventional systemic drugs used in the management of moderate to severe AD.

Military medicine has evolved significantly over the past 50 years, advancing from basic treatments and limited evacuations to sophisticated combat casualty care. Innovations such as hemorrhage control, early blood product administration, and telemedicine have greatly improved battlefield care. Rapid evacuation systems and skilled medical teams have reduced mortality and morbidity rates. Objectives: To review the transformation of the Israel Defense Forces Medical Corps (IDF-MC) in combat casualty care over the past 50 years, focusing on recent applications during the Iron Swords war.

Parvovirus B19 infection has been associated with various clinical entities including musculoskeletal manifestations and the development of different autoimmune diseases. The aim of our study is to examine the musculoskeletal manifestations associated with acute parvovirus B19 infection and the possible development of chronic autoimmune rheumatic diseases.

Gastroesophageal reflux disease (GERD) is a common debilitating chronic disease presenting in two main forms based on esophageal mucosal appearance, the erosive reflux disease (ERD) and the non-erosive reflux disease (NERD). Acid secretion is a key factor in the disease pathogenesis and management. Potent acid-suppressant drugs have been manufactured since the mid of 1970s, initially with histamine-H2-receptors antagonists, and later, inhibitors of the proton pump (H+-K+-ATPase). More recently, potassium-competitive acid blockers (P-CABs), particularly Vonoprazan, have been introduced. Vonoprazan has shown high efficacy and safety profiles and exhibits several advantages that allow to overcome shortcomings of proton pump inhibitors (PPIs).

In this review, we provide an updated summary of Vonoprazan pharmacodynamics and its role in clinical practice for the management of erosive esophagitis and GERD related heartburn. 

Primary hyperoxaluria type 3 (PH3) is a rare autosomal recessive disorder caused by bi-allelic genetic variants in the 4 hydroxy-2 oxoglutarate aldolase (HOGA-1) gene. We report the natural history of PH3 in a 16-patient cohort, 15 from a unique genetically isolated population.

There is an uncertainty regarding the need for screening of HFpEF patients for cardiac amyloidosis (CA) globally. CA remains a disease with very heterogeneous management, particularly in the screening and diagnostic workup. The HF community should aim to educate on CA and improve access to disease-modifying therapy.

This brief report presents updated findings from the previously published CREST study evaluating the safety and effectiveness of 8-week glecaprevir/pibrentasvir (GLE/PIB) in treatment-naïve patients with chronic hepatitis C virus (HCV) infection and compensated cirrhosis. The current study includes an additional 51 patients, presents effectiveness data stratified by additional comorbidities and comedications, and offers insights into healthcare resource utilization.

IgG4-related disease (IgG4-RD) is a rare illness with inflammatory and fibrotic changes in affected organs such as pancreas, thyroid, salivary or lacrimal glands, and retroperitoneal space; rarely other organs may be involved. IgG4-related breast disease (IgG4-BD) is very rare and generally presents as a lump or mastitis. IgG4-BD as a presenting feature of IgG4-RD is extremely rare. Hence, this paper reviews the known (n=48) IgG-BD cases reported in the literature to date.
