Estimated Global Proportions of Individuals With Persistent Fatigue, Cognitive, and Respiratory Symptom Clusters Following Symptomatic COVID-19 in 2020 and 2021.

Importance: Some individuals experience persistent symptoms after initial symptomatic SARS-CoV-2 infection (often referred to as Long COVID).

Objective: To estimate the proportion of males and females with COVID-19, younger or older than 20 years of age, who had Long COVID symptoms in 2020 and 2021 and their Long COVID symptom duration.

Design, Setting, And Participants: Bayesian meta-regression and pooling of 54 studies and 2 medical record databases with data for 1.

A global systematic analysis of the occurrence, severity, and recovery pattern of long COVID in 2020 and 2021.

Importance: While much of the attention on the COVID-19 pandemic was directed at the daily counts of cases and those with serious disease overwhelming health services, increasingly, reports have appeared of people who experience debilitating symptoms after the initial infection. This is popularly known as long COVID.

Objective: To estimate by country and territory of the number of patients affected by long COVID in 2020 and 2021, the severity of their symptoms and expected pattern of recovery.

Media Influence on Anxiety, Health Utility, and Health Beliefs Early in the SARS-CoV-2 Pandemic-a Survey Study.

Background: The psychological effects from the COVID-19 pandemic and response are poorly understood.

Objective: To understand the effects of the pandemic and response on anxiety and health utility in a nationally representative sample of US adults.

Design: A de-identified, cross-sectional survey was administered at the end of April 2020.

Immunological Outcomes of Allergen-Specific Immunotherapy in Food Allergy.

IgE-mediated food allergies are caused by adverse immunologic responses to food proteins. Allergic reactions may present locally in different tissues such as skin, gastrointestinal and respiratory tract and may result is systemic life-threatening reactions. During the last decades, the prevalence of food allergies has significantly increased throughout the world, and considerable efforts have been made to develop curative therapies.

Stop COVID Cohort: An Observational Study of 3480 Patients Admitted to the Sechenov University Hospital Network in Moscow City for Suspected Coronavirus Disease 2019 (COVID-19) Infection.

Background: The epidemiology, clinical course, and outcomes of patients with coronavirus disease 2019 (COVID-19) in the Russian population are unknown. Information on the differences between laboratory-confirmed and clinically diagnosed COVID-19 in real-life settings is lacking.

Methods: We extracted data from the medical records of adult patients who were consecutively admitted for suspected COVID-19 infection in Moscow between 8 April and 28 May 2020.

Perspective: The Role of Human Breast-Milk Extracellular Vesicles in Child Health and Disease.

Human breast milk (HM) contains multiple bioactive substances determining its impact on children's health. Extracellular vesicles (EVs) are a heterogeneous group of secreted nanoparticles that are present in HM and may be partially responsible for its beneficial effects. The precise roles and content of EVs in HM remain largely unknown.

Excessive Media Consumption About COVID-19 is Associated With Increased State Anxiety: Outcomes of a Large Online Survey in Russia.

Background: The COVID-19 pandemic has potentially had a negative impact on the mental health and well-being of individuals and families. Anxiety levels and risk factors within particular populations are poorly described.

Objective: This study aims to evaluate confidence, understanding, trust, concerns, and levels of anxiety during the COVID-19 pandemic in the general population and assess risk factors for increased anxiety.

Uni-center, patient-blinded, randomized, 12-month, parallel group, noninferiority study to compare outcomes of 3-row vs 2-row circular staplers for colorectal anastomosis formation after low anterior resection for rectal cancer.

Background: Colorectal anastomotic leakage (AL) is one of the most serious complications in rectal cancer surgery due to its negative impact on the overall as well as cancer-specific survival. Two-row stapling technique has become standard in low anterior resections (LARs), but has neither alleviated the morbidity, nor reduced the incidence of AL. This is the 1st study that aims to compare the success rate of new 3-row circular staplers compared to that of conventional 2-row staplers in a prospective, randomized clinical trial.
