Male infertility is attributed to multiple factors including high levels of sperm DNA fragmentation (SDF). Conventional semen analysis continues to be the gold standard for diagnosis of male factor infertility around the world. However, the limitations of basic semen analysis have prompted the search for complementary assessments of sperm function and integrity. ⋯ While a controlled degree of DNA nicking is required for appropriate DNA compaction, excessive fragmentation of sperm DNA is linked to impaired male fertility potential, decreased fertilization, poor embryo quality, recurrent pregnancy loss, and failure of assisted reproductive technology procedures. However, there is an ongoing debate regarding whether or not to employ SDF as a routine test for male infertility. This review compiles up-to-date information regarding the pathophysiology of SDF, the currently available SDF tests, and the role of SDF tests in natural and assisted conception conditions.

The aim of this study was to elucidate the influence and molecular mechanism of microRNA-29c-3p (miR-29c-3p) on cell functions of cardiac fibroblasts. ⋯ MiR-29c-3p weakens the over-proliferative and over-migratory potentials in HG-induced cardiac fibroblasts via inactivating the STAT3 signaling.

Due to the COVID-19 pandemic, the first lockdown was implemented in Austria for almost 7 weeks. In contrast to many other countries, medical consultations were permitted, either by telemedicine or at doctors' offices. Nevertheless, restrictions related to this lockdown could possibly cause an increased risk of deterioration in health, especially in diabetes. This study aimed to assess the impact of Austria's first lockdown on laboratory and mental parameters in a type-2 diabetes mellitus cohort. ⋯ Lack of movement and staying at home resulted in a significant weight gain and worsening of mental well-being in type-2 diabetes during the first lockdown in Austria. Thanks to regular medical consultations, laboratory parameters remained stable or even improved. Thus, routine health check-ups in mainly elderly type 2 diabetic patients are essential to minimize the deterioration of health conditions during lockdowns.

Since the first pioneering studies on time-lapse systems (TLSs) for embryo incubation, many things have changed. Two main factors influence the development of modern time-lapse incubators for human in-vitro fertilization (IVF): 1) the switch from traditional cell culture incubators to benchtops incubators, more suitable for human IVF; and 2) the improvement of imaging technology. ⋯ This review aims to describe the history and the different TLSs available in the market, to summarize the research and clinical results obtained by using this technology, and to reflect on how this technology is changing the modern IVF laboratory. The current limitations of TLSs will be also reviewed.

The management of patients with coronary artery disease (CAD) is complex, especially after they have been discharged from hospital after an acute coronary syndrome (ACS), because each patient may have numerous healthcare providers, and follow-up after discharge may be disjointed, or even incomplete. During follow-up after ACS, few patients have treatment intensification; rather, there is actually a major tendency towards reductions in treatment intensity, to the potential detriment of outcomes. We present here guidance from a French expert panel for the optimal management of lipid-lowering therapy up to 1 year after ACS. ⋯ Then, the strategy should be rapidly intensified by adding a PCSK9 inhibitor if the patient does not reach LDL-c levels below 55 mg/dL. We advocate this intensive strategy, which has demonstrated a further reduction in ischemic events, without safety concerns, even for patients who reach very low LDL-cholesterol levels. This approach, comprising few therapeutic steps, aims to rapidly reach LDL-c goals, improve patient compliance, and is an efficient method to fight therapeutic inertia, which remains a major issue.
