Electronic address:

Article Synopsis
  • Progressive cardiac conduction defects, often linked to specific gene variants in SCN5A and CACNA1D, can cause sinoatrial node dysfunction.
  • Researchers created an induced pluripotent stem cell line from a 13-year-old patient with conduction system disease and ventricular tachycardia, carrying variants in SCN5A, CACNA1D, and DSP.
  • The iPSC line showed characteristics of pluripotency, effectively differentiated into all three embryonic germ layers, and maintained normal genetics, paving the way for understanding cardiac arrhythmias and developing personalized treatments.

Article Synopsis
  • Clostridium difficile infection (CDI) is an increasing healthcare problem linked to higher risks and poor outcomes, particularly in frail patients, whose impact on CDI has been insufficiently studied.
  • An analysis of over 144,000 adult CDI patients from the National Readmission Database revealed that 67.88% were frail, with frailty significantly increasing the risk of mortality, complications, and intensive care admission.
  • The findings suggest that frailty should be recognized as a key factor influencing CDI outcomes, which can help clinicians in better risk stratification and developing targeted treatment strategies for affected individuals.

Skin cancer in patients who are co-infected with HIV/ HBV or HIV/HCV: a systematic review.

Arch Dermatol Res

November 2024

Department of Dermatology, SUNY Downstate, 450 Clarkson Ave, Brooklyn, NY, USA.

Skin cancer, the most common cancer in the United States, has been well-described in the literature to be associated with environmental factors including ultraviolet (UV) radiation. However, the effect of chronic viral infections on risk of skin cancer development, particularly in individuals co-infected with Human Immunodeficiency Virus (HIV) and Hepatitis B or C Viruses (HBV/HCV), has yet to be elucidated. This systematic review aims to be one of the first to consolidate existing literature and examine the relationship between skin cancer and HIV/HBV and HIV/HCV co-infections.

Mohs micrographic surgery (MMS) is a precise and effective technique for treating skin cancers, necessitating high accuracy and real-time decision-making to ensure complete tumor removal while preserving healthy tissue. The introduction of the Apple Vision Pro (AVP), an advanced mixed-reality headset, presents a potential technological advancement in surgical practice. The present investigation explores the integration of AVP into Mohs surgery, focusing on its potential to enhance preoperative planning, intraoperative guidance, and postoperative analysis.

Alveolar capillary barrier disruption induces local edema and inflammation that impairs pulmonary function and promotes alveolar destruction in COPD. This study aimed to determine how cigarette smoke modulated the serine-threonine phosphatase protein phosphatase 2 A (PP2A) to alter the barrier function of human lung microvascular endothelial cells (HLMVECs). Cigarette smoke exposure lowered overall PP2A activity and enhanced endothelial permeability in HLMVECs.

Purpose Studies regarding the relationship between age-related macular degeneration (AMD) and diabetic retinopathy (DR) conflict: while some support that AMD is protective against DR, others find the opposite. The mechanism by which AMD may protect against DR is unclear. We sought to assess the association between AMD and DR when controlling for glycemic control in patients with diabetes mellitus (DM) type II.

Article Synopsis
  • The study investigates racial disparities in SARS-CoV-2 vaccination rates among people with HIV (PWH) and those at risk for HIV, focusing on the roles of medical mistrust and vaccine hesitancy.
  • It utilizes data from a diverse cohort and employs various statistical analyses to explore the impact of social demographics on vaccination attitudes and behaviors.
  • Results show that Black participants are significantly more likely to be unvaccinated compared to white participants, primarily due to medical mistrust and vaccine hesitancy, highlighting the urgent need for improving trust in healthcare to address these disparities.

Background: Integrase strand transfer inhibitors (INSTIs) and the menopausal transition have separately been associated with body composition changes in women with HIV (WWH), but their interaction is unknown.

Methods: From 2006-2019, 1131 non-pregnant WWH with viral suppression [(419 who switched to INSTI (INSTI+); 712 who did not switch (INSTI-)] and 887 women without HIV (WWOH) from the Women's Interagency HIV Study were included. Mixed effect models were used to evaluate change in waist circumference (WC) and BMI by menopausal phase defined using anti-Müllerian hormone, a biomarker of ovarian reserve.

HER2 amplification in cervical cancer has been associated with worse clinical prognosis and a potential favorable response to HER2 inhibitors. Immunohistochemistry for the HER2 receptor is a universally accepted surrogate test for HER2 amplification, but no standardized scoring system currently exists for cervical carcinomas. In this study, we investigated HER2 overexpression in cervical squamous cell carcinoma and correlated it with HER2 amplification using fluorescence in situ hybridization (FISH) and molecular methods.

Article Synopsis
  • In medication-resistant epilepsy, surgery aims to achieve seizure freedom while minimizing harm through careful planning based on electroclinical data and neuroimaging techniques.
  • A support vector machine (SVM) was utilized to analyze fast ripple (FR) metrics from patients, achieving a prediction accuracy of 78% for effective surgical resections.
  • Simulations indicated that larger virtual resections often led to improved seizure freedom outcomes, suggesting that targeting high-frequency oscillations may enhance surgical success rates.
