Risk of Substance Use Disorders among Adolescents and Emerging Adults with Type 1 Diabetes: A Population-based Cohort Study.

Pediatr Diabetes 2021 Sep 24. Epub 2021 Sep 24.

Division of Pediatric Endocrinology, Department of Pediatric and Adolescent Medicine, Mayo Clinic, Rochester, Minnesota.

Adolescents and emerging adults with chronic health conditions such as type 1 diabetes mellitus (T1D) are more likely to engage in high-risk behaviors. Previous studies regarding substance use in adolescents and emerging adults with T1D are mostly derived from cross-sectional studies utilizing self-administered questionnaires and are limited by lack of population-based comparison groups. In addition, despite the rising popularity of vaping, little is known about the incidence of vaping in adolescents and emerging adults with T1D. Read More

A population-based study of seasonal variation in children's fractures.

Dan Med J 2021 Sep 15;68(10). Epub 2021 Sep 15.

INTRODUCTION Few Scandinavian studies have studied seasonal variations in paediatric fractures, and the studies that have focused on individual fracture sites. Furthermore, their findings do not coincide as they have described peaks in different seasons. Therefore, we described seasonal variation in the incidence rate (IR) of all paediatric fractures in the 1996-2019 period within a Danish population. Read More

Association between body weight misperception and dietary patterns in Brazilian adolescents: Cross-sectional study using ERICA data.

PLoS One 2021 23;16(9):e0257603. Epub 2021 Sep 23.

Faculty of Health Sciences, Graduate Program of Public Health, University of Brasilia, Brasilia, Federal District, Brazil.

Nonvoluntary or Forced Sex Among Women, by Sexual Identity, Attraction, and Behavior - National Survey of Family Growth, United States, 2011-2017.

MMWR Morb Mortal Wkly Rep 2021 Sep 24;70(38):1326-1331. Epub 2021 Sep 24.

Nonheterosexual (sexual minority) women report experiencing more sexual violence than heterosexual (sexual majority) women (1,2). Sexual minority women are often categorized as a collective whole, which fails to capture the nuances in sexual violence among subgroups of sexual minority women, such as bisexual and lesbian women (3). To estimate the prevalence of lifetime forced vaginal intercourse (forced sex) and of nonvoluntary first vaginal intercourse among women aged 18-44 years in the United States, CDC analyzed data from female respondents who were interviewed during 2011-2017 for the National Survey of Family Growth (NSFG); respondents were stratified by self-reported sexual identity, attraction, and behavior.

Effect of a Mediterranean diet intervention on gastrointestinal function in Parkinson's disease (the MEDI-PD study): study protocol for a randomised controlled trial.

BMJ Open 2021 Sep 22;11(9):e053336. Epub 2021 Sep 22.

Food Science and Human Nutrition Department, University of Florida, Gainesville, Florida, USA.

Introduction: Constipation is a common and sometimes debilitating non-motor symptom of Parkinson's disease (PD) that can result in intestinal inflammation and microbial dysbiosis. The Mediterranean diet, rich in fermentable fibres and anti-inflammatory phenolic compounds, is associated with reduced risk of developing PD and slower progression of parkinsonism. The Mediterranean diet is often recommended for people with PD; however, no studies to date examine this diet as a therapeutic intervention to modulate gastrointestinal (GI) dysfunction. Read More

Exercise effects on DNA methylation in , and in colon tissue from healthy men and women.

Epigenetics 2021 Sep 22. Epub 2021 Sep 22.

Public Health Sciences Division, Fred Hutchinson Cancer Research Center, Seattle, Washington.

Physical activity reduces risk of colon cancer persons by 20-30%. Aberrant methylation patterns are common epigenetic alterations in colorectal adenomas and cancers, and play a role in cancer initiation and progression. Alterations have been identified in normal colon tissue potentially representing a "field cancerization" process, where the normal colon is primed for carcinogenesis. Read More
