Growth differentiation factor 15 (GDF15) levels are associated with malnutrition in acutely admitted older adults.

BACKGROUND AND AIMS: The aging process is often accompanied by high risk of malnutrition and elevated levels of growth differentiation factor 15 (GDF15). GDF15 is an increasingly recognized biomarker for regulation of metabolism, but few studies have investigated the connection between GDF15 and malnutrition in older age and how it relates to other features of aging such as decreased appetite and physical function. Therefore, we investigated the associations between GDF15 levels and nutritional status, appetite, and physical function in acutely admitted older adults. METHODS: Plasma GDF15 levels were measured using immunoassays in 302 older adults (≥65 years) admitted to the emergency department (ED). Nutritional status was evaluated with the Mini Nutritional Assessment Short-Form (MNA®-SF), appetite was evaluated with the Simplified Nutritional Appetite Questionnaire (SNAQ), and physical function was evaluated with handgrip strength (HGS), 30-s chair stand test (30s-RSS), and gait speed (GS). Associations between GDF15 and each outcome was determined by logistic regression adjusted for age, sex, and C-reactive protein (CRP). RESULTS: Each doubling in plasma GDF15 level was associated with an adjusted odds ratio (OR) (95% confidence interval) of 1.59 (1.10-2.29, P = 0.01) for risk of malnutrition compared to normal nutrition and 1.19 (0.85-1.69, P = 0.3)) for malnutrition compared to risk of malnutrition. Each doubling in GDF15 was associated with an adjusted OR of 1.63 (1.21-2.23)) for having poor appetite, 1.46 (1.07-1.99) for having low HGS, 1.74 (1.23-2.51) for having low 30s-RSS, and 1.99 (1.39-2.94) for having low GS. CONCLUSION: Among older adults admitted to the ED, higher GDF15 levels were significantly associated with malnutrition, poor appetite, and low physical function independent of age, sex, and CRP.

Acromegaly management in the Nordic countries: A Delphi consensus survey.

OBJECTIVE: Acromegaly is associated with increased morbidity and mortality if left untreated. The therapeutic options include surgery, medical treatment, and radiotherapy. Several guidelines and recommendations on treatment algorithms and follow-up exist. However, not all recommendations are strictly evidence-based. To evaluate consensus on the treatment and follow-up of patients with acromegaly in the Nordic countries. METHODS: A Delphi process was used to map the landscape of acromegaly management in Denmark, Sweden, Norway, Finland, and Iceland. An expert panel developed 37 statements on the treatment and follow-up of patients with acromegaly. Dedicated endocrinologists (n = 47) from the Nordic countries were invited to rate their extent of agreement with the statements, using a Likert-type scale (1-7). Consensus was defined as ≥80% of panelists rating their agreement as ≥5 or ≤3 on the Likert-type scale. RESULTS: Consensus was reached in 41% (15/37) of the statements. Panelists agreed that pituitary surgery remains first line treatment. There was general agreement to recommend first-generation somatostatin analog (SSA) treatment after failed surgery and to consider repeat surgery. In addition, there was agreement to recommend combination therapy with first-generation SSA and pegvisomant as second- or third-line treatment. In more than 50% of the statements, consensus was not achieved. Considerable disagreement existed regarding pegvisomant monotherapy, and treatment with pasireotide and dopamine agonists. CONCLUSION: This consensus exploration study on the management of patients with acromegaly in the Nordic countries revealed a relatively large degree of disagreement among experts, which mirrors the complexity of the disease and the shortage of evidence-based data.

Impact of androgenic anabolic steroid use on cardiovascular and mental health in Danish recreational athletes: protocol for a nationwide cross-sectional cohort study as a part of the Fitness Doping in Denmark (FIDO-DK) study.

INTRODUCTION: The use of androgenic anabolic steroids (AASs) among recreational athletes is steadily increasing. However, knowledge regarding the potentially harmful effects of AAS primarily originates from case reports and small observational studies. This large-scale study aims to investigate the impact of AAS use on vascular plaque formation, preclinical coronary disease, cardiac function, circulating cardiovascular risk markers, quality of life (QoL) and mental health in a broad population of illicit AAS users. METHODS AND ANALYSES: A nationwide cross-sectional cohort study including a diverse population of men and women aged ≥18 years, with current or previous illicit AAS use for at least 3 months. Conducted at Odense University Hospital, Denmark, the study comprises two parts. In part A (the pilot study), 120 recreational athletes with an AAS history will be compared with a sex-matched and age-matched control population of 60 recreational athletes with no previous AAS use. Cardiovascular outcomes include examination of non-calcified coronary plaque volume and calcium score using coronary CT angiography, myocardial structure and function via echocardiography, and assessing carotid and femoral artery plaques using ultrasonography. Retinal microvascular status is evaluated through fundus photography. Cardiovascular risk markers are measured in blood. Mental health outcomes include health-related QoL, interpersonal difficulties, body image concerns, aggression dimensions, anxiety symptoms, depressive severity and cognitive function assessed through validated questionnaires. The findings of our comprehensive study will be used to compose a less intensive investigatory cohort study of cardiovascular and mental health (part B) involving a larger group of recreational athletes with a history of illicit AAS use. ETHICS AND DISSEMINATION: The study received approval from the Regional Committee on Health Research Ethics for Southern Denmark (S-20210078) and the Danish Data Protection Agency (21/28259). All participants will provide signed informed consent. Research outcomes will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER: NCT05178537.

Paracetamol overdose in Danish children and adolescents during the Covid-19 restrictions.

INTRODUCTION: To assess the effect of long-term isolation on the mental state of Danish youth. This study aimed to investigate trends in paracetamol overdoses among people under 18 years of age in Denmark during Covid-19 restrictions as an indicator of mental health. METHODS: All patients under the age of 18 years presenting with paracetamol overdose at one of the 18 paediatric departments in Denmark from 2016 to 2021 were included. They were identified in all Danish hospital databases using specific diagnostic codes. RESULTS: From 2016 to 2021, a total of 3,217 people under 18 years of age were admitted for paracetamol overdose. Among these, 86% (n = 2,755) were girls and 14% (n = 462) were boys. During 2020, a slight (7%) decrease in admissions was observed among both boys and girls compared with the preceding four-year mean value. In 2021, the number of overdoses among girls exceeded by 35% the former all-time high from 2016. Furthermore, the number of overdoses among girls exceeded the pre-four-year period mean value by 43%. Among boys, an 8% increase was seen from the highest ever previous value recorded in 2019 and a 23% increase compared with the previous four-year mean value. CONCLUSIONS: During the first year of restrictions, a slight decrease in paracetamol overdoses was observed, possibly associated with limited accessibility. The second year showed a considerable increase in paracetamol overdoses, which may imply an affected mental state among youth during the prolonged lockdown restrictions as seen in previous epidemics. Therefore, further studies are warranted to develop a pandemic preparedness plan to protect general mental health. FUNDING: None. TRIAL REGISTRATION: Not relevant.

Inappropriate prescribing in patients with kidney disease: A rapid review of prevalence, associated clinical outcomes and impact of interventions.

BACKGROUND: The prevalence of patients with chronic kidney disease (CKD) and polypharmacy is increasing and has amplified the importance of examining inappropriate prescribing (IP) in CKD. This review focuses on the latest research regarding the prevalence of IP in CKD and the related adverse clinical effects and explores new interventions against IP. METHOD: A literature search was performed using PubMed, EMBASE and the Cochrane Library searching articles published between June 2016 and March 2022. RESULTS: Twenty-seven studies were included. An IP prevalence of 12.6% to 96% and 0.3% to 66% was reported in hospital and outpatient settings, respectively. In nonhospital settings, the prevalence of IP varied between 3.9% and 60%. IP was associated with higher risk of hospitalisation (HR 1.46, 95% CI 1.17-1.81), higher bleeding rate (HR 2.34, 95% CI 1.32 to 3.37) and higher risk of all-cause mortality (OR 1.07, 95% CI 1.02 to 1.13). Three studies reported the impact of interventions on IP. CONCLUSION: This review highlights widespread IP in CKD patients across healthcare settings, with varying prevalence rates. IP is substantially linked to adverse outcomes in patients. While limited interventions show promise, urgent research is needed to develop effective strategies addressing IP and improving CKD patient care.

Educational outcomes and the role of comorbidity among adolescents with type 1-diabetes in Denmark.

AIMS: To examine educational outcomes among adolescents with type 1 diabetes and determine the role of comorbidity. METHODS: We conducted a nationwide register-based cohort study including 3370 individuals born between 1991 and 2003 and diagnosed with type 1 diabetes before the age of 16. They were all matched with up to four individuals without type 1 diabetes on age, gender, parents' educational level and immigration status. Information on comorbidity was based on hospital diagnoses. The individuals were followed in registers to determine whether they finished compulsory school (9th grade, usually at the age of 15-16 years), and were enrolled in secondary education by age 18 years. RESULTS: Individuals with type 1 diabetes were more likely not to complete compulsory school (OR 1.44, 95% CI 1.26-1.64), and not being enrolled in an upper secondary education by age 18 (OR 1.50, 95% CI 1.31-1.73) compared to their peers. A total of 1869 (56%) individuals with type 1 diabetes were registered with at least one somatic (n = 1709) or psychiatric comorbidity (n = 389). Those with type 1 diabetes and psychiatric comorbidity were more likely not to complete compulsory school (OR 2.47, 95% CI 1.54-3.96), and not being enrolled in an upper secondary education by age 18 (OR 3.66, 95% CI 2.27-5.91) compared to those with type 1 diabetes only. Further, there was a tendency towards an association between having somatic comorbidity and adverse educational outcomes (OR 1.25, 95% CI 0.97-1.63; OR 1.26, 95% CI 0.95-1.66) among adolescents with type 1 diabetes. The associations differed markedly between diagnostic comorbidity groups. CONCLUSION: Type 1 diabetes affects educational attainment and participation among adolescents. Psychiatric comorbidity contributes to adverse educational outcomes in this group, and there is a tendency that somatic comorbidity also plays a role.

Whole-body oxidative stress reduction during testosterone therapy in aging men: A randomized placebo-controlled trial.

BACKGROUND: Testosterone replacement therapy in aging men increases lean body mass and decreases whole-body fat. The safety of testosterone replacement therapy concerning cardiovascular disease is unresolved and assessment of whole-body oxidative stress may contribute to future decision making. OBJECTIVES: To determine whole-body oxidative stress during testosterone replacement therapy and placebo in aging men and evaluate if a change in oxidative stress was mediated by changed body composition. MATERIALS AND METHODS: This was a double-blinded, randomized, placebo-controlled study for 24 weeks in 38 men aged 60-78 years with bioavailable testosterone <7.3 nmol/L and waist circumference ≥94 cm who were randomized to testosterone replacement therapy (testosterone gel) (N = 20) or placebo (N = 18). At baseline and after 24 weeks, whole-body oxidative stress was assessed by oxidized derivatives of nucleic acids, 8-oxoguanosine and 8-oxo-2'-deoxyguanosine in 24-h urine samples by ultra-performance liquid chromatography tandem mass spectrometry. Lean body mass and whole-body fat were measured by dual X-ray absorptiometry. Subcutaneous and visceral adipose tissue were estimated by magnetic resonance imaging. Testosterone replacement therapy versus placebo was compared by Mann-Whitney tests on ∆-values (24-0 weeks). RESULTS: Baseline age was 67 (64-72) years (median [interquartile range]), body mass index 29.8 (26.6-33.3) kg/m2 , waist 107 (99-117) cm, and bioavailable testosterone 4.7 (3.7-5.9) nmol/L. During testosterone replacement therapy, 8-oxoguanosine in 24-h urine samples decreased from 21.6 (19.8; 27.7) nm to 15.0 (12.2; 18.8) nm (p = 0.038 vs. placebo), lean body mass increased (p < 0.01) and whole-body fat (p = 0.02) and subcutaneous adipose tissue (p < 0.01) decreased. 8-Oxoguanosine in 24-h urine samples was inversely associated with Δ-lean body mass (ρ = -0.38, p = 0.03), which remained significant after adjusting for Δ-total testosterone. 8-Oxo-2'-deoxyguanosine in 24-h urine samples was unchanged (p = 0.06) during testosterone replacement therapy and Δ-8-oxo-2'-deoxyguanosine in 24-h urine samples was associated with Δ-whole-body fat (kg) (ρ = 0.47, p < 0.01). Δ-Values of oxidative stress biomarkers were not associated with Δ-fasting insulin or Δ-homeostatic model assessment of insulin resistance. DISCUSSION: Oxidative stress decreased during testosterone replacement therapy compared to placebo, which could be mediated by changed body composition. CONCLUSION: Whole-body oxidative stress decreased during 24 weeks of testosterone replacement therapy in aging men.

Formation of ß-Configured Thioglycosides of d-Glucosamine and d-Galactosamine and Synthesis of Protected Human Milk Oligosaccharides.

We report on the stereoselective multigram scale preparation of cyclohexyl- and phenyl thioglycosides of 2-azido-2-deoxy-ß-d-gluco- and galactopyranosides from d-N-acetylglucosamine using a catalytic and solvent-free method. Two of the prepared building blocks were used as key intermediates for the synthesis of human milk oligosaccharides LNT and LNnT in their protected form.

Acute unilateral maculopathy after hand, foot and mouth disease.

Unilateral acute maculopathy is a rare inflammatory macular disorder believed to be caused by viral infection, especially Coxsackievirus. It most commonly affects young healthy adults. This is a case report of unilateral acute maculopathy in a 28-year-old man with concurrent hand, foot and mouth disease. Although the typical acute manifestation of the disease is sudden, severe, unilateral central vision loss, most patients achieve full visual recovery over the course of several weeks without therapy.

Whole genome sequencing and disease pattern in patients with juvenile polyposis syndrome: a nationwide study.

Juvenile polyposis syndrome (JPS) is a hereditary hamartomatous polyposis syndrome characterized by gastrointestinal juvenile polyps and increased risk of gastrointestinal cancer. Germline pathogenic variants are detected in SMAD4 or BMPR1A, however in a significant number of patients with JPS, the etiology is unknown. From Danish registers, and genetic department and laboratories, we identified all patients in Denmark with a clinical diagnosis of JPS and/or a pathogenic variant in BMPR1A or SMAD4. In patients where no variant had been detected, we performed genetic analysis, including whole genome sequencing. We collected clinical information on all patients to investigate the phenotypic spectrum. Sixty-six patients (mean age 40 years) were included of whom the pathogenic variant was unknown in seven patients. We detected a pathogenic variant in SMAD4 or PTEN in additional three patients and thus ≈ 95% of patients had a pathogenic germline variant. Endoscopic information was available in fifty-two patients (79%) and of these 31 (60%) fulfilled the clinical criteria of JPS. In 41 patients (79%), other types of polyps than juvenile had been removed. Our results suggest that almost all patients with a clinical diagnosis of JPS has a pathogenic variant in mainly BMPR1A, SMAD4, and more rarely PTEN. However, not all patients with a pathogenic variant fulfil the clinical criteria of JPS. We also demonstrated a wide clinical spectrum, and that the histopathology of removed polyps varied.

Design and Baseline Characteristics of STEP-HFpEF Program Evaluating Semaglutide in Patients With Obesity HFpEF Phenotype.

BACKGROUND: The majority of patients with heart failure with preserved ejection fraction (HFpEF) have the obesity phenotype, but no therapies specifically targeting obesity in HFpEF exist. OBJECTIVES: The aim of this study was to describe the design and baseline characteristics of 2 trials of semaglutide, a glucagon-like peptide-1 receptor agonist, in patients with the obesity HFpEF phenotype: STEP-HFpEF (Semaglutide Treatment Effect in People with obesity and HFpEF; NCT04788511) and STEP-HFpEF DM (Semaglutide Treatment Effect in People with obesity and HFpEF and type 2 diabetes; NCT04916470). METHODS: Both STEP-HFpEF and STEP-HFpEF DM are international multicenter, double-blind, placebo-controlled trials that randomized adults with HFpEF and a body mass index ≥30 kg/m2 to once-weekly semaglutide at a dose of 2.4 mg or placebo. Participants were eligible if they had a left ventricular ejection fraction (LVEF) ≥45%; NYHA functional class II to IV; a Kansas City Cardiomyopathy Questionnaire (KCCQ)-Clinical Summary Score (CSS) <90 points; and ≥1 of the following: elevated filling pressures, elevated natriuretic peptides plus structural echocardiographic abnormalities, recent heart failure hospitalization plus ongoing diuretic use, and/or structural abnormalities. The dual primary endpoints are the 52-week change in the KCCQ-CSS and body weight. RESULTS: In STEP-HFpEF and STEP-HFpEF DM (N = 529 and N = 617, respectively), nearly half were women, and most had severe obesity (median body mass index of 37 kg/m2) with typical features of HFpEF (median LVEF of 57%, frequent comorbidities, and elevated natriuretic peptides). Most participants received diuretic agents and renin-angiotensin blockers at baseline, and approximately one-third were on mineralocorticoid receptor antagonists. Sodium-glucose cotransporter-2 inhibitor use was rare in STEP-HFpEF but not in STEP HFpEF DM (32%). Patients in both trials had marked symptomatic and functional impairments (KCCQ-CSS ∼59 points, 6-minute walking distance ∼300 m). CONCLUSIONS: In total, STEP-HFpEF program randomized 1,146 participants with the obesity phenotype of HFpEF and will determine whether semaglutide improves symptoms, physical limitations, and exercise function in addition to weight loss in this vulnerable group.

Quality of life, patient satisfaction, and cardiovascular outcomes of the randomised 2 x 3 factorial Copenhagen insulin and Metformin therapy (CIMT) trial - A detailed statistical analysis plan.

Background: The evidence on the effects of metformin and insulin in type 2 diabetes patients on quality of life, patient satisfaction, and cardiovascular outcomes is unclear. Methods: The Copenhagen Insulin and Metformin Therapy (CIMT) trial is an investigator-initiated multicentre, randomised, placebo-controlled trial with a 2 × 3 factorial design conducted at eight hospitals in Denmark. Participants with type 2 diabetes were randomised to metformin (n = 206) versus placebo (n = 206); in combination with open-label biphasic insulin aspart one to three times daily (n = 137) versus insulin aspart three times daily in combination with insulin detemir once daily (n = 138) versus insulin detemir once daily (n = 137).We present a detailed description of the methodology and statistical analysis of the clinical CIMT outcomes including a detailed description of tests of the assumptions behind the statistical analyses. The outcomes are quality of life (Short Form Health Survey (SF-36)), Diabetes Medication Satisfaction Questionnaire, and Insulin Treatment Satisfaction Questionnaire (assessed at entry and 18 months after randomisation) and cardiovascular outcomes including time to a composite of either myocardial infarction, stroke, peripheral amputation, coronary revascularisation, peripheral revascularisation, or death. Discussions: This statistical analysis plan ensure the highest possible quality of the subsequent post-hoc analyses. Trial registration: The protocol was approved by the Regional Committee on Biomedical Research Ethics (H-D-2007-112), the Danish Medicines Agency (EudraCT: 2007-006665-33 CIMT), and registered within ClinicalTrials.gov (NCT00657943, 8th of April 2008).

Two-year effect of semaglutide 2.4 mg on control of eating in adults with overweight/obesity: STEP 5.

OBJECTIVE: This study evaluated the effect of once-weekly semaglutide 2.4 mg on 2-year control of eating. METHODS: In STEP 5, adults with overweight/obesity were randomized 1:1 to semaglutide 2.4 mg or placebo, plus lifestyle modification, for 104 weeks. A 19-item Control of Eating Questionnaire was administered at weeks 0, 20, 52, and 104 in a subgroup of participants. P values were not controlled for multiplicity. RESULTS: In participants completing the Control of Eating Questionnaire (semaglutide, n = 88; placebo, n = 86), mean body weight changes were -14.8% (semaglutide) and -2.4% (placebo). Scores significantly improved with semaglutide versus placebo for Craving Control and Craving for Savory domains at weeks 20, 52, and 104 (p < 0.01); for Positive Mood and Craving for Sweet domains at weeks 20 and 52 (p < 0.05); and for hunger and fullness at week 20 (p < 0.001). Improvements in craving domain scores were positively correlated with reductions in body weight from baseline to week 104 with semaglutide. At 104 weeks, scores for desire to eat salty and spicy food, cravings for dairy and starchy foods, difficulty in resisting cravings, and control of eating were significantly reduced with semaglutide versus placebo (all p < 0.05). CONCLUSIONS: In adults with overweight/obesity, semaglutide 2.4 mg improved short- and longer-term control of eating associated with substantial weight loss.

Evaluation of Multi-Frequency Bioelectrical Impedance Analysis against Dual-Energy X-ray Absorptiometry for Estimation of Low Muscle Mass in Older Hospitalized Patients.

The accuracy of multi-frequency (MF) bioelectrical impedance analysis (BIA) to estimate low muscle mass in older hospitalized patients remains unclear. This study aimed to describe the ability of MF-BIA to identify low muscle mass as proposed by The Global Leadership Initiative on Malnutrition (GLIM) and The European Working Group on Sarcopenia in Older People (EWGSOP-2) and examine the association between muscle mass, dehydration, malnutrition, and poor appetite in older hospitalized patients. In this prospective exploratory cohort study, low muscle mass was estimated with MF-BIA against dual-energy X-ray absorptiometry (DXA) in 42 older hospitalized adults (≥65 years). The primary variable for muscle mass was appendicular skeletal muscle mass (ASM), and secondary variables were appendicular skeletal muscle mass index (ASMI) and fat-free mass index (FFMI). Cut-off values for low muscle mass were based on recommendations by GLIM and EWGSOP-2. MF-BIA was evaluated against DXA on the ability to estimate absolute values of muscle mass by mean bias, limits of agreement (LOA), and accuracy (5% and 10% levels). Agreement between MF-BIA and DXA to identify low muscle mass was evaluated with sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). The association between muscle mass, dehydration, malnutrition, and poor appetite was visually examined with boxplots. MF-BIA overestimated absolute values of ASM with a mean bias of 0.63 kg (CI: -0.20:1.46, LOA: -4.61:5.87). Agreement between MF-BIA and DXA measures of ASM showed a sensitivity of 86%, specificity of 94%, PPV of 75% and NPV of 97%. Boxplots indicate that ASM is lower in patients with malnutrition. This was not observed in patients with poor appetite. We observed a tendency toward higher ASM in patients with dehydration. Estimation of absolute ASM values with MF-BIA should be interpreted with caution, but MF-BIA might identify low muscle mass in older hospitalized patients.

Distinct gastric phenotype in patients with pathogenic variants in SMAD4: A nationwide cross-sectional study.

Background and study aims In most patients with juvenile polyposis Syndrome, it is possible to detect a pathogenic germline variant in SMAD4 or BMPR1A . It is well known that patients with a pathogenic variant in SMAD4 have a higher risk of gastric polyposis and gastric cancer compared to BMPR1A carriers, but the natural history of gastric involvement is poorly described. We aimed to systematically review endoscopic and histopathological gastric findings in Danish patients with pathogenic variants in SMAD4. Patients and methods This was a retrospective, cross-sectional study including endoscopic and histological gastric findings in all known Danish patients with pathogenic variants in SMAD4 . The patients were identified by data from various registries as well as from clinical genetic departments and laboratories. Results We identified 41 patients (2-72 years) with a pathogenic SMAD4 variant . In 31 patients, we were able to retrieve information on upper gastrointestinal endoscopy. Eighty-seven percent had at least one gastric abnormality including erythema (72 %) and edema (72 %). Half of the patients also had vulnerability of the mucosa and 68 % had gastric polyposis. An increasing frequency of abnormalities were observed with increasing age. Gastric cancer was diagnosed in 5 % of the cases and 22 % had a gastrectomy mainly because of massive polyposis. Conclusions This study showed that most patients with pathogenic SMAD4 variants have a distinct phenotype of the gastric mucosa, and with an increasing severity in the elderly patients. These findings provide new insights into the natural history of gastric manifestations in patients with pathogenic SMAD4 variants.

Infliximab biosimilar-to-biosimilar switching in patients with inflammatory rheumatic disease: clinical outcomes in real-world patients from the DANBIO registry.

OBJECTIVE: Successful uptake of biosimilars in rheumatology is limited by lack of real-world evidence regarding effectiveness of biosimilar-to-biosimilar switching. We investigated infliximab biosimilars CT-P13-to-GP1111 switching among patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA). METHODS: Observational cohort study from the DANBIO registry. Patients were classified as originator-naïve or originator-experienced. Retention rates of 1-year GP1111 treatment were explored (Kaplan-Meier). We identified baseline factors (at the time of switch) associated with withdrawal of GP1111 (multivariable Cox-regression analyses with HRs including originator treatment history). Changes in subjective and objective measures of disease activity 4 months before and after the switch were assessed in individual patients. RESULTS: Of 1605 patients (685 RA, 314 PsA and 606 AxSpA, median disease duration was 9 years, 37% in Clinical Disease Activity Index/Ankylosing Spondylitis Disease Activity Score remission), 1171 were originator-naïve. Retention rates at 1-year were 83% (95% CI: 81% to 85%) and 92% (95% CI: 90% to 95%) for the originator-naïve and originator-experienced, respectively. GP1111 retention rates were higher in originator-experienced compared to originator-naïve with RA (HR=0.4 (95% CI: 0.2 to 0.7)) and PsA (HR=0.2 (95% CI: 0.1 to 0.8)), but not significantly for AxSpA: HR=0.6 (95% CI: 0.3 to 1.2). Lower disease activity was associated with higher retention. Changes in disease activity preswitch and postswitch were close to zero. CONCLUSION: This real-world observational study of more than 1600 patients with inflammatory arthritis showed high 1-year retention following a nationwide infliximab biosimilar-to-biosimilar switch. Retention was higher in originator-experienced and in patients with low disease activity, suggesting outcomes to be affected by patient-related rather than drug-related factors.

Two-year effects of semaglutide in adults with overweight or obesity: the STEP 5 trial.

The STEP 5 trial assessed the efficacy and safety of once-weekly subcutaneous semaglutide 2.4 mg versus placebo (both plus behavioral intervention) for long-term treatment of adults with obesity, or overweight with at least one weight-related comorbidity, without diabetes. The co-primary endpoints were the percentage change in body weight and achievement of weight loss of ≥5% at week 104. Efficacy was assessed among all randomized participants regardless of treatment discontinuation or rescue intervention. From 5 October 2018 to 1 February 2019, 304 participants were randomly assigned to semaglutide 2.4 mg (n = 152) or placebo (n = 152), 92.8% of whom completed the trial (attended the end-of-trial safety visit). Most participants were female (236 (77.6%)) and white (283 (93.1%)), with a mean (s.d.) age of 47.3 (11.0) years, body mass index of 38.5 (6.9) kg m-2 and weight of 106.0 (22.0) kg. The mean change in body weight from baseline to week 104 was -15.2% in the semaglutide group (n = 152) versus -2.6% with placebo (n = 152), for an estimated treatment difference of -12.6 %-points (95% confidence interval, -15.3 to -9.8; P < 0.0001). More participants in the semaglutide group than in the placebo group achieved weight loss ≥5% from baseline at week 104 (77.1% versus 34.4%; P < 0.0001). Gastrointestinal adverse events, mostly mild-to-moderate, were reported more often with semaglutide than with placebo (82.2% versus 53.9%). In summary, in adults with overweight (with at least one weight-related comorbidity) or obesity, semaglutide treatment led to substantial, sustained weight loss over 104 weeks versus placebo.

Presentation, Management, and Outcomes of Urinary Bladder Paraganglioma: Results From a Multicenter Study.

CONTEXT: Urinary bladder paraganglioma (UBPGL) is rare. OBJECTIVE: We aimed to characterize the presentation and outcomes of patients diagnosed with UBPGL. METHODS: We conducted a multicenter study of consecutive patients with pathologically confirmed UBPGL evaluated between 1971 and 2021. Outcomes included repeat bladder surgery, metastases, and disease-specific mortality. RESULTS: Patients (n=110 total; n=56 [51%] women) were diagnosed with UBPGL at a median age of 50 years (interquartile range [IQR], 36-61 years). Median tumor size was 2 cm (IQR, 1-4 cm). UBPGL was diagnosed prior to biopsy in only 37 (34%), and only 69 (63%) patients had evaluation for catecholamine excess. In addition to the initial bladder surgery, 26 (25%) required multiple therapies, including repeat surgery in 10 (9%). Synchronous metastases were present in 9 (8%) patients, and 24 (22%) other patients with UBPGL developed metachronous metastases at a median of 4 years (IQR, 2-10 years) after the initial diagnosis. Development of metachronous metastases was associated with younger age (hazard ratio [HR] 0.97; 95% CI, 0.94-0.99), UBPGL size (HR 1.69; 95% CI, 1.31-2.17), and a higher degree of catecholamine excess (HR 5.48; 95% CI, 1.40-21.39). Disease-specific mortality was higher in patients with synchronous metastases (HR 20.80; 95% CI, 1.30-332.91). Choice of initial surgery, genetic association, sex, or presence of muscular involvement on pathology were not associated with development of metastases or mortality. CONCLUSIONS: Only a minority of patients were diagnosed before biopsy/surgery, reflecting need for better diagnostic strategies. All patients with UBPGL should have lifelong monitoring for development of recurrence and metastases.

Intramuscular myxoma of the biceps brachii muscle: a case report.

Intramuscular myxoma (IM) is a rare benign tumour. It may occur at any age but most commonly occurs among older women. The preoperative diagnosis of IM is complicated. The diagnosis can only be definitively established by histopathological examination. The treatment of choice is radical surgical excision. We report a case of a 41-year-old woman with an IM of the biceps brachii muscle.
