Understanding the additional impact of prediabetes and type 2 diabetes mellitus on vitamin C requirements in people living with obesity.

Obesity and diabetes are known to negatively affect vitamin C status. However, whether the presence of diabetes, in addition to obesity, contributes an additional impact on vitamin C status is currently uncertain. In a cohort of 152 adults living with obesity, we assessed metabolic and nutrient parameters in participants without diabetes (n = 92), and with prediabetes (n = 22) and type 2 diabetes mellitus (T2DM; n = 35).

Patient perceptions of barriers to attending annual diabetes review and foot assessment in general practice: a qualitative study.

Introduction Regular diabetic foot checks, at least annually, are important for early identification of risk factors and prevention of ulceration and amputation. To ensure this, most general practices in Aotearoa New Zealand (NZ) offer free annual diabetes reviews (ADRs) which include a comprehensive foot evaluation. However, attendance rates at these ADRs are low.

Estimating Vitamin C Intake Requirements in Diabetes Mellitus: Analysis of NHANES 2017-2018 and EPIC-Norfolk Cohorts.

Vitamin C is an essential enzyme cofactor and antioxidant with pleiotropic roles in human physiology. Circulating vitamin C concentrations are lower in people with diabetes mellitus, suggesting a higher dietary requirement for the vitamin. We interrogated the NHANES 2017-2018 and EPIC-Norfolk datasets to compare vitamin C requirements between those with and without diabetes mellitus using dose-concentration relationships fitted with sigmoidal (four-parameter logistic) curves.

Comparing Literature- and Subreddit-Derived Laboratory Values in Polycystic Ovary Syndrome (PCOS): Validation of Clinical Data Posted on PCOS Reddit Forums.

Background: Polycystic ovary syndrome (PCOS) is a heterogeneous condition that affects 4% to 21% of people with ovaries. Inaccessibility or dissatisfaction with clinical treatment for PCOS has led to some individuals with the condition discussing their experiences in specialized web-based forums.

Objective: This study explores the feasibility of using such web-based forums for clinical research purposes by gathering and analyzing laboratory test results posted in an active PCOS forum, specifically the PCOS subreddit hosted on Reddit.

People with diabetes and hypovitaminosis C fail to conserve urinary vitamin C.

Background: Hypovitaminosis C has negative health consequences. People with diabetes and hypovitaminosis C may fail to conserve vitamin C in the urine, thereby displaying evidence of inappropriate renal leak of vitamin C. This study describes the relationship between plasma and urinary vitamin C in diabetes, with a focus on the clinical characteristics of participants with renal leak.
