Protective Modifications in Ophthalmology Practice during COVID-19 Pandemic: Challenges and Lessons Learned.
Ophthalmology is a specialty which involves close contact with patients. Personal protective equipment (PPE) along with modifications in examination techniques and equipment are needed to avoid spread of coronavirus infectious disease (COVID-19) to health professionals. This communication aims to highlight and critically analyse the measures suggested to control this spread. ⋯ As with any practice, triage is cornerstone. Use of disinfectants, good personal hygiene practices and PPE for patients and staff, must be adopted for safe ophthalmology practices. Key Words: COVID-19, Ophthalmology, Personal protective equipment (PPE).

Ischemia and reperfusion (I/R) in the intestine could lead to severe endothelial injury, compromising intestinal motility. Reportedly, estradiol can control local and systemic inflammation induced by I/R injury. Thus, we investigated the effects of estradiol treatment on local repercussions in an intestinal I/R model. ⋯ Collectively, our findings indicate that estradiol treatment can modulate the deleterious intestinal effects of I/R injury. Thus, estradiol mediates the improvement in gut barrier functions and prevents intestinal dysfunction, which may reduce the systemic inflammatory response.

Infantile hemangioma (IH), which threatens the physical and mental health of patients, is the most common benign tumor in infants. Previously, we found that 15,16-dihydrotanshinone I (DHTS) was significantly more effective at inhibiting hemangioma proliferation in vitro and in vivo than the first-line treatment propranolol. To investigate the underlying mechanism of DHTS, we used EOMA cells as a model to study the effect of DHTS. ⋯ Thus, we investigated HIF-1α expression at protein and mRNA levels. Our results revealed that DHTS downregulated HIF-1α expression by interfering in its posttranscriptional processing, and the RNA-binding protein HuR participated in this mechanism. Our findings provide a basis for clinical transformation of DHTS and insight into pathogenic mechanisms involved in IH.

Medical education and assessment processes in India are expected to undergo a paradigm shift with the introduction of the National Medical Commission Act, 2019. The Government of India intends to introduce a national exit test (NEXT) which is supposed to act as a single examination for graduation from medical school, granting licence to practice modern medicine, and allocating postgraduate residencies. ⋯ These options include theoretical (multiple assessment methods) with clinical examinations, multiple-choice question (MCQ)-based examination with separate clinical examination, only an MCQ-based examination, and multistep examination including screening followed by mixed assessment methods and clinical evaluation. We discuss the possible strengths and challenges of different options of implementing NEXT, and the caveats of the options.
