Sleep quality in children with hepatic glycogen storage diseases, a prospective observational pilot study.

Background: Hepatic glycogen storage diseases (GSDs) are characterised by enzyme defects affecting liver glycogen metabolism, where carbohydrate supplementation to prevent overnight hypoglycaemia is common. Concerns around sleep quality in hepatic GSDs relate to emerging evidence that overnight dysglycaemia impacts sleep quality.

Methods: This prospective observational study reported sleep quality and duration in children with hepatic GSDs over 7 days utilising: actigraphy (Actiwatch 2 by Phillips Respironics), sleep diaries, proxy reported age-appropriate sleep and quality-of-life (QoL) questionnaires, in the context of nocturnal glycaemic profiles continuous glucose monitor (CGM, Dexcom G6) and nocturnal dietary management strategies.

Abalones at risk: A global Red List assessment of Haliotis in a changing climate.

There is increasing awareness that marine invertebrates such as abalones are at risk from the combined stressors of fishing and climate change. Abalones are an important marine fishery resource and of cultural importance to Indigenous and non-Indigenous people. A highly priced marine delicacy, they are inherently vulnerable: individuals are slow-growing and long-lived and successful reproduction requires dense assemblages.

Adolescent menstrual cycle pattern, body mass index, endocrine and ovarian ultrasound characteristics of PCOS and future fertility, cardiovascular-, and metabolic health: a 25-year longitudinal follow-up study.

Study Question: What is the predictive value of oligomenorrhea and other PCOS diagnostic characteristics in adolescence (age 15-18 years) for future fertility and cardiovascular and metabolic health at adult age?

Summary Answer: Adolescents with oligomenorrhea are more often treated to conceive but are as likely to have as much children as those with regular periods, while persisting oligomenorrhea may associate more often with cardiovascular or metabolic problems.

What Is Known Already: Adolescents with oligomenorrhea have a high risk for adult PCOS associated with subfertility due to ovulatory disorders and long-term health risks. Longitudinal studies to estimate the extent of these risks with input starting at adolescence and covering the complete reproductive lifespan are lacking.

The Natural Products Magnetic Resonance Database (NP-MRD) for 2025.

The Natural Products Magnetic Resonance Database (NP-MRD; https://np-mrd.org) is a comprehensive, freely accessible, web-based resource for the deposition, distribution, extraction, and retrieval of nuclear magnetic resonance (NMR) data on natural products (NPs). The NP-MRD was initially established to support compound de-replication and data dissemination for the NP community.
