Dysregulation of Nitrosylation Dynamics Promotes Nitrosative Stress and Contributes to Cardiometabolic Heart Failure with Preserved Ejection Fraction.

Background: Recent reports suggest increased myocardial iNOS expression leads to excessive protein -nitrosylation, contributing to the pathophysiology of HFpEF. However, the relationship between NO bioavailability, dynamic regulation of protein -nitrosylation by trans- and de-nitrosylases, and HFpEF pathophysiology has not been elucidated. Here, we provide novel insights into the delicate interplay between NO bioavailability and protein -nitrosylation in HFpEF.

Evaluating general practitioners' focused lung ultrasound competence and findings in patients with suspected community-acquired pneumonia in general practice.

Objectives: To evaluate general practitioners' (GPs') ability to perform focused lung ultrasound (FLUS) following a training program and assess FLUS feasibility in general practice. Also, to describe FLUS findings and evaluate GPs' ability to interpret these in adults with acute lower respiratory tract infection (LRTI) when pneumonia is suspected and assess GPs' perception of FLUS impact.

Methods: Nine GPs, using point-of-care ultrasound, completed a FLUS training program.

Ultrasound education, competencies and expected future use among medical interns in Denmark: a national cross-sectional study.

Background: Point-of-care ultrasound is increasingly used across medical specialties, calling for timely and relevant ultrasound education in specialty training. To enable customizing such education, we aimed to explore medical interns' received ultrasound education during medical school and internship, perceived scanning competencies, evaluation of received education, future expectations for using ultrasound, and tendencies for perceiving ultrasound competence.

Methods: This was a national cross-sectional study.

Weight Loss Induces Changes in Vitamin D Status in Women with Obesity but not in Men: a Randomized Clinical Trial.

Context: Obesity is associated with low vitamin D and recent studies have suggested a difference in vitamin D metabolism between females and males.

Objective: The aim of this study was to investigate the effects of weight loss on vitamin D status in individuals with obesity, and secondarily, whether vitamin D metabolism differs between women and men.

Methods: Secondary analysis from a randomized placebo-controlled trial, designed to investigate the efficacy of 52 weeks of treatment with either liraglutide, exercise or combined, compared with placebo on weight loss maintenance after an 8-week low-calorie diet-induced weight loss in 195 individuals with obesity (BMI 32-43 kg/m2).

Heterogenous Origins of Calcium Homeostasis Disorders Arising from Five Heterozygous Calcium-Sensing Receptor Variants.

Context And Objectives: The human calcium-sensing receptor (CaSR) plays a key role in calcium homeostasis, and most identified CASR variants are associated with hypercalcemic and hypocalcemic disorders. Here we characterized the pharmacological implications of five heterozygous CASR variants from individuals with familial hypocalciuric hypercalcemia 1 [FHH1: Y63C, I81T, Q459R, W818stop] or autosomal dominant hypocalcemia 1 [ADH1: R955stop].

Methods: Total and cell surface expression levels of wild-type (WT) and variant CaSRs expressed in human embryonic kidney 293T (HEK293T) cells were determined using ELISA, and the pharmacological properties of the receptors were delineated in two functional assays.

Ibrutinib as treatment for Bing-Neel syndrome reclassified as glioblastoma: a case report.

Background: Glioblastoma is a highly malignant disease with limited treatment options. Ibrutinib, a covalent Bruton tyrosine kinase inhibitor, is an oral agent with manageable side effects used for hematological diseases including Waldenström macroglobulinemia. We present the case of a 69-year-old Caucasian male patient treated with ibrutinib for suspected Bing-Neel syndrome (BNS), which following a biopsy, was reclassified as glioblastoma.

The effect of focused lung ultrasonography on antibiotic prescribing in patients with acute lower respiratory tract infections in Danish general practice: study protocol for a pragmatic randomized controlled trial (PLUS-FLUS).

Background: The use of antibiotics is a key driver of antimicrobial resistance and is considered a major threat to global health. In Denmark, approximately 75% of antibiotic prescriptions are issued in general practice, with acute lower respiratory tract infections (LRTIs) being one of the most common indications. Adults who present to general practice with symptoms of acute LRTI often suffer from self-limiting viral infections.

Case report: Death caused by multi-organ metastatic calcifications as a result of intramuscular injections with paraffin oil.

In this forensic case report, we present autopsy findings from a young male in his thirties who had been self-injecting paraffin oil into his upper extremities 8 years prior to death. The injections induced an inflammatory response, leading to granuloma formation. This, in turn, resulted in severe hypercalcemia.

Factors affecting point-of-care ultrasound implementation in general practice: a survey in Danish primary care clinics.

Objective: The implementation of point-of-care ultrasound (POCUS) in general practice varies, but it is unknown what determines this variation. The purpose of this study was to explore (1) the overall proportion of POCUS-users among general practitioners (GPs), (2) the current use of POCUS by GPs, (3) factors related to the implementation of POCUS in general practice and (4) GPs' concerns related to POCUS use in general practice.

Design: An online survey was distributed in June 2019.

Patient perspectives on data sharing regarding implementing and using artificial intelligence in general practice - a qualitative study.

Background: Due to more elderly and patients with complex illnesses, there is an increasing pressure on the healthcare system. General practice especially feels this pressure as being the first point of contact for the patients. Developments in digitalization have undergone fast progress and data-driven artificial intelligence (AI) has shown great potential for use in general practice.

Machine learning in general practice: scoping review of administrative task support and automation.

Background: Artificial intelligence (AI) is increasingly used to support general practice in the early detection of disease and treatment recommendations. However, AI systems aimed at alleviating time-consuming administrative tasks currently appear limited. This scoping review thus aims to summarize the research that has been carried out in methods of machine learning applied to the support and automation of administrative tasks in general practice.

Participatory research: a Priority Setting Partnership for chronic musculoskeletal pain in Denmark.

Objectives: Patient and stakeholder engagements in research have increasingly gained attention in healthcare and healthcare-related research. A common and rigorous approach to establish research priorities based on input from people and stakeholders is the James Lind Alliance Priority Setting Partnership (JLA-PSP). The aim of this study was to establish research priorities for chronic musculoskeletal (MSK) pain by engaging with people living with chronic MSK pain, relatives to people living with chronic MSK pain, healthcare professionals (HCP), and researchers working with chronic MSK pain.

Use of primary health care and radiological imaging preceding a diagnosis of rheumatoid arthritis: a nationwide cohort study in Denmark.

Objective: To explore health-care use in the 12 months preceding a diagnosis of RA in Denmark.

Methods: We conducted a population-based cohort study using data from national registries. Every patient diagnosed with RA in 2014-18 was matched to 10 reference individuals without RA from the Danish background population.

General Practitioners' Perspectives on Appropriate Use of Ultrasonography in Primary Care in Denmark: A Multistage Mixed Methods Study.

Purpose: Researchers aimed to describe general practitioners' understanding of appropriate ultrasound use, to record actual scanning practices of early adopters in general practice, and to identify differences between attitudes and actual practice via a mixed methods analysis.

Methods: This study was part of a larger multistage mixed methods research framework exploring the use of ultrasound in general practice in Denmark. We used an exploratory sequential approach in the data collection with initial qualitative findings from an interview study applied to building a quantitative questionnaire utilized in a cohort study.

Background: Eight percent of all child and adolescent general practice consultations are due to musculoskeletal conditions, with pain as the most frequent symptom. Despite the commonality of musculoskeletal pain, limited knowledge exists about care-seeking children and adolescents with musculoskeletal pain. The purpose of this study was to describe characteristics of children and adolescents consulting their general practitioner with musculoskeletal pain.

Learning strategies of general practitioners striving to achieve point-of-care ultrasound competence: a qualitative study.

Background: Point-of-care ultrasonography (POCUS) is increasingly used in general practice despite the lack of official educational programmes or guidelines for general practitioners (GPs).

Aim: To explore how GPs have learnt to use POCUS and which barriers they have encountered in their learning process.

Design And Setting: Qualitative study conducted in office-based general practice in Denmark.

A cost-minimisation analysis of performing point-of-care ultrasonography on patients with vaginal bleeding in early pregnancy in general practice: a decision analytical model.

Background: Spotting and light vaginal bleeding are common and usually harmless symptoms in early pregnancy. Still, vaginal bleeding may be the first sign of an abortion and often causes distress to pregnant women and leads to an expectation of an ultrasonography examination of the uterus. As point-of-care ultrasonography (POCUS) is increasingly being integrated into general practice, these patients may be clinically evaluated and managed by general practitioners (GPs).

The Online Patient Satisfaction Index for Patients With Low Back Pain: Development, Reliability, and Validation Study.

Background: Low back pain is highly prevalent, and most often, a specific causative factor cannot be identified. Therefore, for most patients, their low back pain is labeled as nonspecific. Patient education and information are recommended for all these patients.
