Magnesium

Female patients diagnosed with lipedema will be divided into two groups based on their Pittsburgh Sleep Quality Index (PSQI) scores: PSQI ≤ 5 and PSQI \> 5. Age, body mass index (BMI), education level, menopausal status (reproductive period, perimenopausal period, postmenopausal period), number of births, duration of illness, occupation, marital status, disease stage, lipedema type, lower extremity functional scale, and the World Health Organization Quality of Life Scale - Short Form (Physical Health, Psychological Health, Social Relationships...)

This prospective randomized controlled study will be conducted to compare the effects of preoperative oral magnesium and intraoperative IV magnesium on the incidence and severity of emergence delirium in children undergoing adenotonsillectomy using sevoflurane anesthesia.

Cognitive impairments such as memory impairments, word-finding difficulties, compromised orientation and perception are often observed in stroke patients. Low serum-mg-concentrations are associated with cognitive impairments in ischemic stroke patients one month after stroke onset. It is not clear, if cognitive impairments after stroke is caused by the mg-deficiency or by the stroke itself. Until now, no studies investigating the relationship between mg-concentration, stroke severity and cognition during treatment course are available. Thus, this study aimed to investigate the relationship between mg-concentration and cognition of stroke patients.

Individuals with gastrointestinal diseases - such as Crohn's disease, ulcerative colitis, ileostomy, or bile acid diarrhoea - are at increased risk of magnesium deficiency. Magnesium is a vital mineral that supports many essential functions in the body, including muscle contraction, nerve signalling, heart rhythm, and bone health. Deficiency may contribute to fatigue, muscle cramps, abnormal heart rhythms, and reduce the quality of life. The purpose of this study is to investigate the prevalence of magnesium deficiency in individuals with these conditions and to identify the most accurate and practical methods for assessing magnesium status in clinical care. Although plasma magnesium is commonly used in routine blood tests, it represents only about 1% of the body's total magnesium and may not reflect true magnesium levels within cells or tissues. Hence, this study compares several different ways of measuring magnesium, including: * Plasma magnesium * Magnesium levels in red and white blood cells (PBMC, RBC, and buffy coat) * Magnesium levels in muscle tissue (via biopsy) * A magnesium retention test, based on how much magnesium is excreted after an infusion The study includes four groups: 1. Patients with inflammatory bowel disease. 2. Patients with an ileostomy. 3. Patients with bile acid diarrhoea. 4. Healthy individuals (control group). All participants will provide blood and urine samples, and some may undergo optional biopsies of muscle or intestinal tissue. Participants will also complete questionnaires and undergo tests of muscle strength and body composition. The findings are expected to enhance the understanding and detection of magnesium deficiency in patients with gastrointestinal diseases and to aid in the development of more effective tools for identifying and treating this common yet often overlooked condition.

This trial has a randomized, single-blind, single-center, parallel-controlled design, with participant screening and trial implementation conducted at Guangdong Provincial People's Hospital. The study evaluate the efficacy of oral magnesium L-threonate supplementation on improving menopausal symptoms and quality of life among peri/post-menopausal women. This trial aims to explore whether oral magnesium L-threonate supplementation could alleviate menopausal syndromes. Participants will randomly assigned to conduct oral magnesium L-threonate supplementation or placebo for 8 weeks. Face-to-face and internet follow up will be conducted once per 2 weeks.
