Practice GuidelineA new normal with cataract surgery during COVID-19 pandemic.
Cataract is the second leading cause of preventable blindness on the globe. Several programs across the country have been running efficiently to increase the cataract surgical rates and decrease blindness due to cataract. The current COVID-19 pandemic has led to a complete halt of these programs and thus accumulating all the elective cataract procedures. ⋯ These guidelines will be applicable to all practice settings including tertiary institutions, corporate and group practices and individual eye clinics. The guidelines include triage, use of personal protective equipment, precautions to be taken in the OPD and operating room as well for elective cataract screening and surgery. These guidelines have been prepared based on current situation but are expected to evolve over a period of time based on the ongoing pandemic and guidelines from GoI.

SARS-CoV-2-caused COVID-19 cases are growing globally, calling for developing effective therapeutics to control the current pandemic. SARS-CoV-2 and SARS-CoV recognize angiotensin-converting enzyme 2 (ACE2) receptor via the receptor-binding domain (RBD). ⋯ The 18F3-recognizing epitopes on RBD did not overlap with the ACE2-binding sites, whereas those recognized by 7B11 were close to the ACE2-binding sites, explaining why 7B11 could, but 18F3 could not, block SARS-CoV or SARS-CoV-2 RBD binding to ACE2 receptor. Our study provides an alternative approach to prevent SARS-CoV-2 infection using anti-SARS-CoV nAbs.

Practice GuidelineCOVID-19 pandemic and lacrimal practice: Multipronged resumption strategies and getting back on our feet.
The aim of this review was to propose multi-pronged resumption strategies for lacrimal practice in an effort to plan a sustainable recommencement of elective surgeries after we emerge from the peak of COVID-19 pandemic. The strategies for lacrimal practice were classified into 7 subtypes, and each of the blueprints were reassessed based on existing information on resumption strategies of elective surgeries from other specialties in COVID-19 era. The specific needs of lacrimal practice were then added to construct algorithms summarizing the resumption strategies. ⋯ It is equally important to remember that COVID-19 crisis is a dynamic situation and constantly evolving, hence the strategies provided are subject to change. Strict adherence to standard COVID-19 guidelines combined with effective testing and personal protection strategies can ensure slow yet smooth and safe return to full lacrimal practice after the COVID-19 pandemic calms down. The local government directives, individual and institutional discretion are advised.

In December 2019, coronavirus Disease 2019 (COVID-19) occurred in Wuhan, Hubei Province, China. The disease has rapidly spread from Wuhan to other regions. ⋯ The clinical symptoms, laboratory results and imaging reports of patients with COVID-19 in Hunan area are significantly different from those in Wuhan area. For non-Wuhan epidemic areas, more attention should be paid to nucleic acid test results of throat swabs and stools, and it is not easily to diagnose based on clinical symptoms and CT results. Reduced whole blood lymph count can be used as an adjuvant diagnosis of early SARS-CoV-2 infection. Attention should be paid to asymptomatic carriers, which is of great significance for the control of the global epidemic.
