Peripheral artery disease (PAD), defined as lower extremity arterial disease, constitutes an underestimated aspect of the menopause-associated risk of atherosclerotic cardiovascular disease (ASCVD). Accumulation of ASCVD risk factors, such as atherogenic dyslipidaemia, diabetes, and arterial hypertension, after the transition to menopause may contribute to atherosclerotic plaque formation in peripheral arteries. However, inconsistency exists among studies as to whether transition to menopause increases the risk of PAD, although early menopause (<45 years) or premature ovarian insufficiency may accelerate peripheral atherosclerotic plaque formation.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic became superimposed on the pre-existing obesity and diabetes mellitus (DM) pandemics. Since COVID-19 infection alters the metabolic equilibrium, it may induce pathophysiologic mechanisms that potentiate new-onset DM, and we evaluated this issue.

Method: A systematic review of the literature published from the 1 January 2020 until the 20 July 2023 was performed (PROSPERO registration number CRD42022341638).

Article Synopsis
  • Undifferentiated early gastric cancer (UD-EGC) can be treated effectively with endoscopic submucosal dissection (ESD), and this study focused on understanding recurrence rates and risk factors related to this treatment.
  • Data was gathered from 17 centers, involving 71 patients, indicating a low recurrence rate of 5.6% after an average follow-up period of about 29 months.
  • Factors like lymphovascular and perineural invasion were found to be significantly linked to local recurrence, while lesion size was not a predictor, suggesting that ESD is a viable initial treatment option for UD-EGC when certain risk factors are absent.

Background: It has been reported that hepatitis B virus (HBV) double mutations (A1762T, G1764A) are an aetiological factor of hepatocellular carcinoma (HCC). However, it is unclear who is prone to develop HCC, among those infected with the mutant. Exploring HBV quasispecies, which are strongly influenced by host immune pressure, may provide more information about the association of viral factors and HCC.

Article Synopsis
  • The study investigated the outcomes of patients with systemic sclerosis (SSc) who contracted COVID-19 across different waves of the pandemic, highlighting a lack of data for this specific group.
  • A total of 333 SSc patients were analyzed, revealing a reduction in severe outcomes, hospitalizations, and deaths from wave 1 to waves 2 and 3.
  • The findings suggest that younger demographics, lower use of high-dose corticosteroids, and possibly improved healthcare responses contributed to better outcomes for SSc patients as the pandemic progressed.

Background When treating periprosthetic femoral fractures (PPF) around polished taper slip stems (PTS), determining which patients can be successfully treated with internal fixation can be challenging. We have described the subsidence-in-centraliser (SINC) sign as a radiographic feature of PPF around PTS stems. We hypothesise that a positive SINC sign can help predict a poorer outcome for the fixation of these fractures.

Prognostic Factors and Resectability Predictors in Insular Gliomas: A Systematic Review.

J Neurol Surg A Cent Eur Neurosurg

January 2024

Division of Medicine, University College London Medical School, London, United Kingdom of Great Britain and Northern Ireland.

Background:  Insular gliomas (INGs) remain a surgically intimidating glioma subgroup encased by eloquent cortical parcels and white matter language tracts, and traversed by multiple middle cerebral artery branches. The predictive power of prognostic factors affecting overall survival (OS), progression-free survival (PFS), and resectability of INGs remain disputed. This comprehensive systematic review analyses prognostic factors and resectability predictors of INGs substantiating pragmatic management options.

Is Essential for Cardiac Development and Function.

Cells

August 2023

Zebrafish Disease Model Laboratory, Center for Clinical, Experimental Surgery & Translational Research, Biomedical Research Foundation, Academy of Athens, 11527 Athens, Greece.

Article Synopsis
  • - Cardiovascular diseases (CVDs) are the leading global cause of death, and genetic and environmental factors contribute to the risk of developing conditions like Coronary Artery Disease (CAD), prompting the need to explore related genes like CFDP1.
  • - Research using zebrafish, a model organism, indicated that knockouts of CFDP1 result in arrhythmic hearts and impaired cardiac function, linking it to Wnt signaling pathways during valve development while not affecting Notch signaling.
  • - The findings suggest that CFDP1 is crucial for cardiac development, revealing a novel phenotype possibly relevant for humans with CFDP1 mutations, which might increase their risk of CAD.

Muscle wasting is one of the main causes for exercise intolerance and ventilatory inefficiency in patients with heart failure and a strong predictor of frailty and reduced survival. The prevalence of sarcopenia is at least 20% in patients with heart failure. Patients with heart failure often have subclinical systemic inflammation, which may exert sustained effects on skeletal muscle.

Testosterone levels in men begin declining in the early years of adulthood, with a 1-2% reduction/year. Low testosterone levels in men are associated with obesity, metabolic syndrome, diabetes mellitus, dyslipidaemia, hypertension and increased cardiovascular mortality. However, observational studies of testosterone levels in males and their relationship with peripheral arterial disease (PAD) have yielded mixed results; only some cohorts show a clear association with low free testosterone levels.

Minimum resolution requirements of digital pathology images for accurate classification.

Med Image Anal

October 2023

Wellcome/EPSRC Centre for Interventional and Surgical Sciences, Charles Bell House, 43-45 Foley Street, Fitzrovia, London, W1W 7TS, United Kingdom; Department of Computer Science, University College London, Gower Street, London, WC1E 6BT, United Kingdom.

Digitization of pathology has been proposed as an essential mitigation strategy for the severe staffing crisis facing most pathology departments. Despite its benefits, several barriers have prevented widespread adoption of digital workflows, including cost and pathologist reluctance due to subjective image quality concerns. In this work, we quantitatively determine the minimum image quality requirements for binary classification of histopathology images of breast tissue in terms of spatial and sampling resolution.
