Background: Increasing maternal body mass index (BMI) represents a risk factor for Gestational Diabetes Mellitus (GDM) and adverse obstetrical and perinatal outcomes. Objective: To stratify clinical outcomes for pregnancies affected by GDM according to maternal BMI. Methods: Retrospective cohort study including individuals ≥18 years of age who were diagnosed with GDM from 2018 to 2022. Universal GDM screening was employed with a 50 g oral glucose challenge test ± a 100 g oral glucose tolerance test. Maternal demographics, preexisting medical conditions, and selected obstetric and neonatal morbidities were evaluated. Results: A total of 2193 pregnancies in 2110 women affected by GDM were identified. This included 506 (23.0%) with normal baseline maternal BMI, 596 (27.2%) with overweight, and 1091 (49.7%) with obese BMI. Adverse maternal outcomes were more frequent in the obese compared to overweight or normal BMI categories (cesarean delivery: normal 26.9% vs. overweight 28.5% vs. obese 40.9%; p < 0.001; hypertensive disorders of pregnancy: normal 8.7% vs. overweight 12.1% vs. obese 16.8%; p < 0.001). Postpartum glucose intolerance was higher in women with obesity (normal 7.3% vs. overweight 5.9% vs. obese 14.9%; p < 0.001). Infants born to mothers with obesity had higher birthweights (normal 3.3 kg vs. overweight 3.4 kg vs. obese 3.5 kg; p < 0.001), were more likely to have neonatal hypoglycemia (normal 29.4% vs. overweight 24.3% vs. obese 41.9%; p < 0.001) and require intensive care unit admission (normal 8.1% vs. overweight 5.9% vs. obese 11.9%; p < 0.001). Conclusions: Patients with GDM and baseline BMI in the obese range experienced the highest rate of adverse outcomes, while those with overweight BMI had similar outcomes to individuals who had normal BMI at baseline.

Abstract The widespread use of statins for cardiovascular diseases has unveiled a new subset of inflammatory myopathy, immune-mediated necrotizing myopathy (IMNM). We describe below an unusual case of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) myopathy. A 64-year-old male individual with type 2 diabetes, hyperlipidemia, and coronary artery disease presented with progressive proximal muscle weakness and pain for 3 months. He took atorvastatin 40 mg for 4 years, which was discontinued due to elevated liver enzymes and resumed treatment with rosuvastatin 5 mg later due to worsening hyperlipidemia. Physical examination showed significant weakness of the hip, shoulder girdle, and biceps/triceps. Creatinine kinase (CK) was found to be 232.48 µkat/L (13 921 IU/L) (normal: 0.833-5.133 µkat/L; 50-308 IU/L). Electromyography and left vastus lateralis muscle biopsy showed findings of myonecrosis. Anti-HMGCR assay was strongly positive with antibodies &gt; 200 chemiluminescent units (CU) (normal: 0-20 CU). He was started on prednisone followed by human-immunoglobulin (IVIG) which led to a decline in CK. Statin-induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare side effect of statins. Although statins come with a good side-effect profile, one should be aware of marked, persistent elevations in muscle enzyme levels. Prompt confirmation with antibody levels, drug discontinuation, and early initiation of immunosuppression can lead to good outcomes.
