Calcitonin Gene-Related Peptide Levels in Children and Adolescents With Primary Headache Disorder.

ObjectiveThis study aimed to investigate calcitonin gene-related peptide (CGRP) levels in children and adolescents with primary headache.MethodsAll patients underwent blood sampling regardless of their headache state (ictal or interictal) on the day of examination. The patients were grouped based on their headache diagnosis (migraine, tension-type headache, or mixed).

Rare MTNR1B variants causing diminished MT2 signalling associate with elevated HbA levels but not with type 2 diabetes.

Aims/hypothesis: An intronic variant (rs10830963) in MTNR1B (encoding the melatonin receptor type 2 [MT2]) has been shown to strongly associate with impaired glucose regulation and elevated type 2 diabetes prevalence. However, MTNR1B missense variants have shown conflicting results on type 2 diabetes. Thus, we aimed to gain further insights into the impact of MTNR1B coding variants on type 2 diabetes prevalence and related phenotypes.

Primary Aldosteronism: Clinical Characteristics of Patients with a Paradoxical Increase in P-Aldosterone in Response to Captopril Challenge Test.

A proportion of patients with primary aldosteronism (PA) have a paradox increasein plasma-Aldosterone (P-Aldosterone) concentration (PAC) during the Captopril Challenge Test (CCT). This study aimed to investigate if a paradoxical rise in PAC during CCT, was associated with clinical characteristics or outcomes inpatients with PA. We hypothesized that a paradoxical response to CCT is ameasure of disease severity, reflected by a higher baseline aldosterone/renin-ratio (ARR).

Circadian rhythm and the influence of light on parameters related to calcium metabolism in stroke patients admitted for rehabilitation.

Hospitalized stroke patients are at high risk of developing circadian disruption due to lack of natural sunlight. This may affect the circadian rhythm of the calcium metabolism. This study is a secondary explorative analysis from a Randomized Controlled Trial.

Heavy resistance training provides short-term benefits on bone formation in well-functioning older adults.

Objectives: Maintained bone health is critical for independent living when aging. Currently, multimodal exercise regimes including weight-bearing exercises with impact are prescribed as optimal for maintaining bone health, while there is less consensus on the effects of resistance training at different intensities upon bone. Here we examined whether bone health was positively influenced by 1 year of supervised resistance training at two different intensities.

Melatonin secretion across puberty: A systematic review and meta-analysis.

Background: Melatonin levels decrease with aging and substantially during puberty. Studies have presented distinct melatonin levels in patients with disorders related to their pubertal development compared to healthy controls. The discrepancy suggests that a decrease in melatonin concentrations seen during adolescence might be related to the physical, hormonal, and/or neuronal alterations that occur during the pubertal period.

Lower Bone Mineral Density in Female Elite Athletes With Menstrual Dysfunction From Mixed Sports.

Menstrual dysfunction (MD) in female athletes might be indicative of the syndrome of relative energy deficiency in sports (REDs), associated with, e.g., impaired bone health, an increased risk of injury, and decreased performance.

Bone mineral density and the risk of kidney disease in patients with type 1 diabetes.

Aim: To explore the association between bone disorder and the risk for progression of diabetic kidney disease (DKD) in persons with type 1 diabetes mellitus (T1DM).

Methods: In this prospective cohort study the association between bone mineral density (BMD), bone-derived factors (sclerostin, Dickkopf-1, and osteoprotegerin (OPG)), and four outcomes were investigated: 1) progression of albuminuria; 2) decline in estimated glomerular filtration rate (eGFR) ≥30 %; 3) kidney failure (KF); and 4) a composite kidney outcome consisting of at least one of the outcomes.

Results: In 318 participants (median follow-up time 5.

Unfavourable glucose metabolism is associated with functional somatic disorders. A cross-sectional general population-based study: The DanFunD study.

Objectives: Several studies have observed associations between unfavorable levels of blood glucose metabolic markers (i.e., fasting glucose, fasting insulin, glycated hemoglobin (HbA1c), and insulin resistance (HOMA-IR)) and functional somatic disorder (FSD).

The association between salivary oxytocin, age, and puberty in children with and without OCD.

The oxytocin system has been thought to contribute to obsessive-compulsive disorder (OCD). Few studies, only involving adults, have investigated this hypothesis and have found inconsistent results regarding oxytocin system activity and OCD. We investigated whether salivary oxytocin concentrations differed between children and adolescents with and without OCD and qualified our comparative analysis by investigating the possible covariates age, pubertal stage, and sex.

The associations between functional vitamin K status and all-cause mortality, cardiovascular disease and end-stage kidney disease in persons with type 1 diabetes.

Background And Aim: Vitamin K deficiency is common in persons with kidney disease, which is a known complication of diabetes. We aimed to assess the association of vitamin K status as reflected by plasma dephosphorylated-uncarboxylated matrix Gla protein (dp-ucMGP) with mortality, cardiovascular disease (CVD) and progression to end-stage kidney disease (ESKD) in persons with type 1 diabetes.

Materials And Methods: We analysed plasma dp-ucMGP in stored baseline samples from a cohort of 667 persons with type 1 diabetes (baseline visit: 2009-2011).

Biomarkers of bone metabolism in [Ra] RaCl therapy - association with extent of disease and prediction of overall survival.

Background: The alpha-emitting radionuclide therapy [Ra]RaCl (Radium-223) improves overall survival (OS) and time to symptomatic skeletal event (SSE) in patients with metastatic castration-resistant prostate cancer (mCRPC). Evidence suggests that the effect of Radium-223 is partly exerted through an impact on the surrounding bone matrix. We hypothesized that bone metabolism markers (BMM) could provide predictive information regarding response to Radium-223.

Feasibility Study of Community-Based Training for Musculoskeletal Health Promotion.

To minimize fracture risk, multimodal training regimens are recommended. However, their effectiveness in community settings remains uncertain. This study evaluated the feasibility of 19-weeks of multimodal training in a local community center with emphasis on musculoskeletal health in postmenopausal women.

Half-Life and Clearance of Cardiac Troponin I and Troponin T in Humans.

Background: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes. More precise timing of myocardial injuries necessitates separation of these 2 components.

Evaluating routine blood and cerebrospinal fluid samples in narcolepsy patients.

Cerebrospinal fluid hypocretin-1 is proven to be a precise diagnostic marker of narcolepsy Type 1 (NT1). However other characteristics of cerebrospinal fluid and blood parameters have not yet been described. The objective of this study was to evaluate the differences in routine blood and cerebrospinal fluid analyses between NT1 patients and patients suspected of hypersomnia.

Optic disc drusen: Dystrophic calcification, a potential target for treatment.

Optic disc drusen (ODD) are calcified, acellular bodies, seen in the optic nerve head of up to 2% of the population. Although seldomly affecting visual acuity, visual field defects are common, and severe, ischemic complications causing irreversible vision loss are known to occur. Different treatment strategies for ODD have been explored, but so far without success.

Once-weekly semaglutide versus placebo in adults with increased fracture risk: a randomised, double-blinded, two-centre, phase 2 trial.

Background: Previous studies have indicated that glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) may enhance bone formation and have neutral or beneficial effects on fracture risk. We evaluated the effect of the GLP-1RA semaglutide on the bone formation marker Procollagen type I N-terminal propeptide (PINP) in adults with increased fracture risk.

Methods: This randomised, placebo-controlled, double-blinded, phase 2 clinical trial was conducted at two public hospitals in Denmark.
