Study Question: Can genome-wide genotyping data be analysed using a hypothesis-driven approach to enhance the understanding of the genetic basis of severe spermatogenic failure (SPGF) in male infertility?
Summary Answer: Our findings revealed a significant association between SPGF and the gene and identified three novel genes (, , and ) along with 32 potentially pathogenic rare variants in 30 genes that contribute to this condition.
What Is Known Already: SPGF is a major cause of male infertility, often with an unknown aetiology. SPGF can be due to either multifactorial causes, including both common genetic variants in multiple genes and environmental factors, or highly damaging rare variants.
Background: Dosimetry in intraoperative electron radiotherapy (IOERT) poses distinct challenges, especially with inclined applicators deviating from international protocols. Ion recombination in ionization chambers, electron beam degradation due to scattering in cylindrical applicators, coupled with a lack of a well-defined beam quality surrogate, complicate output factor determination with ionization chambers. Synthetic diamond-based detectors, offer potential solutions; however, their suitability requires further exploration.

The COVID-19 pandemic has resulted in disproportionate consequences for ethnic minority groups and Indigenous Peoples. We present an application of the Priority Public Health Conditions (PPHC) framework from the World Health Organisation (WHO), to explicitly address COVID-19 and other respiratory viruses of pandemic potential. This application is supported by evidence that ethnic minority groups were more likely to be infected, implying differential exposure (PPHC level two), be more vulnerable to severe disease once infected (PPHC level three) and have poorer health outcomes following infection (PPHC level four).

Generally, plants gain access to valuable resources including nutrients and water through the AM symbiosis and are more resistant to pests. Nevertheless, aphids' performance improves on mycorrhizal plants, and it remains unclear whether a more nutritious food source and/or attenuated defenses are the contributing factors.

Health systems have an important role to play in tackling these health inequities. Health systems based on comprehensive Primary Health Care (PHC) are best placed to tackle health inequities because PHC encompasses a whole-of-society approach to health.

SAN spontaneous activity relies on various ion currents in the plasma membrane (voltage clock), but intracellular Ca2+ ([Ca2+]i) release via ryanodine receptor 2 (RYR2; Ca2+ clock) plays an important synergetic role. Whereas remodeling of voltage-clock components has been revealed in HF, less is known about possible alterations to the Ca2+ clock.

Methods: To decipher AMPK roles in the heart, we generated a cardio-specific inducible model of gene deletion of the main cardiac catalytic subunit of AMPK (Ampkα2) in mice.
Introduction: The diagnosis and management of atopic dermatitis (AD) is extensively addressed in detailed clinical guidelines. However, the high heterogeneity regarding presentation and progression and the increasingly broad therapeutic landscape suggest a complex real-world scenario, leading to multiple trajectories of AD patients.
Methods: Using a Delphi methodology for assessing the degree of consensus, we explored the views of a panel of dermatologists regarding the patients' trajectory through the diagnosis (block 1), treatment (block 2), and long-term management (block 3) of AD.
Objectives: a) to analyze the evidence available about poor adherence/non-adherence, including prevalences, associated factors, and interventions in ulcerative colitis (UC) patients; b) to provide a framework to improve poor adherence/non-adherence.
Methods: a qualitative approach was used. A literature review was performed using Medline.
To establish practical recommendations for the management of patients with psoriatic arthritis (PsA) with particular clinical situations that might lead to doubts in the pharmacological decision-making. A group of six expert rheumatologists on PsA identified particular clinical situations in PsA. Then, a systematic literature review (SLR) was performed to analyse the efficacy and safety of csDMARDs, b/tsDMARDs in PsA.
