Int Arch Allergy Immunol 2021 Sep 21:1-10. Epub 2021 Sep 21.

Department of Otolaryngology-Head and Neck Surgery, Renmin Hospital of Wuhan University, Wuhan, China.

Introduction: We explored the cross-reactivity among 19 common allergen sources and evaluated the influence of serum IgE concentrations and the number of sensitized allergens on the incidence of allergic symptoms.

Methods: We conducted this cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 2005-2006 which is a program of studies designed to assess the health and nutritional status of adults and children in the USA. After excluding participants with missing data from the allergen IgE test, allergy questionnaire, and respiratory health questionnaire, a total of 7,224 participants aged 6 years and older were included, as children younger than 6 years old did not complete all 19 allergen-specific IgE tests.

Diabet Med 2021 Sep 21:e14695. Epub 2021 Sep 21.

Manchester University Hospitals NHS Foundation Trust, Manchester Academic Health Science Centre, Manchester, UK.

The daily complexities of insulin therapy and glucose variability in type 1 diabetes still pose significant challenges, despite advancements in modern insulin analogues. Minimising hypoglycaemia and optimising time spent within target glucose range are recommended to reduce the risk of diabetes-related complications and distress. Access to structured education and adjuvant diabetes technologies such as insulin pumps and glucose sensors, are recommended by National Institute for Health and Care Excellence (NICE) to enable people with type 1 diabetes achieve their glycaemic goals.

Incorporating label correlations into deep neural networks to classify protein subcellular location patterns in immunohistochemistry images.

Proteins 2021 Sep 21. Epub 2021 Sep 21.

Institute of Image Processing and Pattern Recognition, Shanghai Jiao Tong University, and Key Laboratory of System Control and Information Processing, Ministry of Education of China, Shanghai, China.

Analysis of protein subcellular localization is a critical part of proteomics. In recent years, as both the number and quality of microscopic images are increasing rapidly, many automated methods, especially convolutional neural networks, have been developed to predict protein subcellular location(s) based on bioimages, but their performance always suffers from some inherent properties of the problem. First, many microscopic images have non-informative or noisy sections, like unstained stroma and unspecific background, which affect the extraction of protein expression information. Read More

The role of fetal surveillance in monochorionic twins: review of the current findings.

Minerva Obstet Gynecol 2021 Sep 21. Epub 2021 Sep 21.

Department of Women's Health, Albert Einstein School of Medicine, São Paulo-SP, Brazil.

Maternal age has increased significantly over the years and assisted reproduction techniques are becoming more available in less developed countries, contributing to the rising number of multiple gestations. Multiple pregnancy is associated with greater risk for both the mother and the fetus than a singleton pregnancy, and needs well-trained professionals to assist and surveil its progression. This review aims to describe the available evidence and summarize the current recommendations for fetal surveillance and delivery timing for monochorionic gestations. Read More
