Diabetic retinopathy (DR), a common complication of both type 1 and type 2 diabetes, is rarely expressed at a level greater than background retinopathy during childhood and adolescence. Epidemiological studies in paediatric diabetic patients together with data from the Diabetes Control and Complications Trial have demonstrated the importance of glycaemic control in delaying or preventing the development of DR; thus, the incidence of DR has declined somewhat over the past two decades. Both prepubertal and postpubertal years with diabetes contribute to the overall probability of DR development. In addition to duration of disease and degree of glycaemic control, other risk factors for DR development include elevated blood pressure, lipid profiles, serum levels of advanced glycation endproducts, evidence for early stage atherosclerosis, increased calibre of retinal blood vessels and several genetic factors, such as enzymes involved in glucose and lipid metabolism. Annual screening is recommended, with mydriatic stereoscopic fundus photography being the most sensitive detection method. Both pathophysiology and treatment in paediatric populations are essentially the same as described for adult populations, with treatment usually not required until adulthood is reached.

In Brazil, pre-exposure prophylaxis (PrEP) is freely available to individuals at high risk of HIV infection. However, knowledge and perception of PrEP can act as barriers to its access and use. This study evaluated PrEP knowledge and perception among healthcare workers in the Unified Health System in a Brazilian capital.

Historical studies performed nearly a century ago using mouse skin models identified two key steps in cancer evolution: initiation, a likely mutational event, and promotion, driven by inflammation and cell proliferation. Initiation was proposed to be permanent, with promotion as the critical rate-limiting step for cancer development. Here, we carried out whole genome sequencing to demonstrate that initiated cells with thousands of mutagen-induced mutations can persist for long periods and are not removed by cell competition or by immune intervention, thus mimicking the persistence of cells with cancer driver mutations in normal human tissues.

Methamphetamine use among sexual minority men (SMM) has been associated with poor ART adherence, and reduced initiation and adherence to PrEP. From May 2021 to May 2023, 226 SMM were enrolled in , a culturally responsive smartphone application to reduce methamphetamine use and improve sexual health. Using a status-neutral approach, an ordinal variable reflected participants' placement on the HIV Prevention/Care Continuum, from HIV-positive, not taking ART, to HIV-negative, currently taking PrEP.

Background: This study aims to analyze the patient characteristics, clinical outcomes, and contemporary trends concerning type A aortic dissection (TAAD) in previous recipients of abdominal solid organ transplantation (ASOT) in the United States.
Methods: The National Inpatient Sample was queried to identify all patients aged ≥18 with TAAD and a history of ASOT (TAAD-ASOT) between 2002 and 2015Q3 using ICD-9 diagnosis and procedure codes. Baseline characteristics and in-hospital outcomes were compared between TAAD-ASOT patients and TAAD patients without a history of ASOT (TAAD-non-ASOT).
Genetic factors contribute to the development of metabolic syndrome and subsequent arterial hypertension (AH). The study of the T786C polymorphism of the endothelial nitric oxide synthase (eNOS) gene in arterial hypertension is important as its correlation with adipokine imbalance is a novelty area to find associations between hypertension development, obesity, and heredity. The purpose of the current study was to investigate serum adipokines levels, depending on the T786C polymorphism of the eNOS in patients with arterial hypertension.
