Patients with prediabetes improve insulin resistance after surgery for primary hyperparathyroidism.

BACKGROUND: The objective of this study was to evaluate the evolution of insulin resistance at 12 months after parathyroidectomy for primary hyperparathyroidism according to the preoperative severity of glucose metabolism abnormalities. METHODS: Observational study of patients who underwent parathyroidectomy between 2016 and 2021. Prediabetes and insulin resistance were defined as fasting glucose ≥1.00 g/L (American Diabetes Association) and homeostatic model assessment of insulin resistance >2.5, respectively. RESULTS: A total of 231 patients were included. Preoperatively, 75 patients (32%) had prediabetes, and 108 patients (47%) had insulin resistance. At 12 months postoperative, homeostatic model assessment of insulin resistance values significantly decreased in patients with prediabetes (-0.69; P = .04) and in patients with insulin resistance (-0.85; P < .001). In patients with prediabetes, 48/75 (64%) decreased their insulin resistance, including 15/48 (31%) with normalization of fasting glucose. In multivariate analysis, preoperative prediabetes (1.82, 1.03-3.21; P = .037) or preoperative homeostatic model assessment of insulin resistance >2.5 (3.90, 2.23-6.75; P < .001) remained independent predictors for insulin resistance reduction observed between preoperative and 12 months postoperative. CONCLUSION: Parathyroidectomy is more likely to reduce insulin resistance in patients with primary hyperparathyroidism and prediabetes or in patients with higher preoperative homeostatic model assessment of insulin resistance values. These data support the use of the preoperative prediabetes criterion in addition to the international workshop criteria for parathyroidectomy to better select patients for surgery.

Prognostic indicators in pituitary adenoma surgery: a comprehensive analysis of surgical outcomes and complications.

Objective: The primary aim of this study was to identify predictive factors associated with onset of de-novo clinically significant pituitary insufficiencies following endoscopic endonasal surgery (EES) for pituitary adenomas. The secondary objective explored the predictive factors of surgical success. Methods: A retrospective analysis was conducted on 211 patients who underwent EES. Logistic regression models were employed for the primary and secondary objectives. Patients were stratified into specific groups based on surgical indications and prolactin levels for nuanced analysis. Results: Significant predictors for de-novo pituitary insufficiencies included male sex (OR 3.3, CI95% 1.3-8.1, p=0.01), immediate postoperative insufficiencies (OR 5.6, CI95% 2.8-11.1, p<0.001), and HYPRONOS criteria (OR 5.7, CI95% 1.6-20.9, p=0.008). For surgical success, preoperative insufficiencies (OR 0.7, CI95% 0.5-0.9, p=0.008), repeat surgeries (OR 0.1, CI95% 0-0.4, p=0.001), and gonadotroph or somatotroph adenomas were significant. Age and adenoma size were not predictive in multivariate analysis. Furthermore, we observed a "dip and recover" effect of prolactin after surgery and lower prolactin levels at follow-up (< 3 ng/ml) are correlated with more anterior pituitary insufficiencies than normoprolactinemic patients (p = 0.004). Conclusion: This study identifies key predictors for outcomes in pituitary surgery. Our research is the first to employ individualized success criteria for EES, challenging existing perceptions about the role of age and adenoma size. These findings open avenues for nuanced, individualized preoperative risk assessment and postoperative management.

Multiple endocrine neoplasia type 1 caused by mosaic mutation: clinical follow-up and genetic counseling?

MEN1 is an autosomal dominant hereditary syndrome characterized by several endocrine tumors, in most cases affecting the parathyroid glands, pancreas, and anterior pituitary. It is the result of inactivating mutations in the tumor suppressor gene MEN1. More than 1300 different mutations have been identified in this gene. Mosaic MEN1 mutations have been previously described in only a few patients in the literature. In this paper, we provide a review of six cases of MEN1 mosaicism reported in the literature supplemented with six additional cases described by the French TENgen network of laboratories. This review highlights that (i) MEN1 mosaicism is not associated with a mild phenotype and results in the same natural history as heterozygous MEN1 mutation and (ii) that more systematic detection of MEN1 mosaic mutation enables improvements in both patient monitoring and genetic counseling.

Long-Term Evolution of Malnutrition and Loss of Muscle Strength after COVID-19: A Major and Neglected Component of Long COVID-19.

Post-acute consequences of COVID-19, also termed long COVID, include signs and symptoms persisting for more than 12 weeks with prolonged multisystem involvement; most often, however, malnutrition is ignored. METHOD: The objective was to analyze persistent symptoms, nutritional status, the evolution of muscle strength and performance status (PS) at 6 months post-discharge in a cohort of COVID-19 survivors. RESULTS: Of 549 consecutive patients hospitalized for COVID-19 between 1 March and 29 April 2020, 23.7% died and 288 patients were at home at D30 post-discharge. At this date, 136 of them (47.2%) presented persistent malnutrition, a significant decrease in muscle strength or a PS ≥ 2. These patients received dietary counseling, nutritional supplementation, adapted physical activity guidance or physiotherapy assistance, or were admitted to post-care facilities. At 6 months post-discharge, 91.0% of the 136 patients (n = 119) were evaluated and 36.0% had persistent malnutrition, 14.3% complained of a significant decrease in muscle strength and 14.9% had a performance status > 2. Obesity was more frequent in patients with impairment than in those without (52.8% vs. 31.0%; p = 0.0071), with these patients being admitted more frequently to ICUs (50.9% vs. 31.3%; p = 0.010). Among those with persistent symptoms, 10% had psychiatric co-morbidities (mood disorders, anxiety, or post-traumatic stress syndrome), 7.6% had prolonged pneumological symptoms and 4.2% had neurological symptoms. CONCLUSIONS: Obese subjects as well as patients who have stayed in intensive care have a higher risk of functional loss or undernutrition 6 months after a severe COVID infection. Malnutrition and loss of muscle strength should be considered in the clinical assessment of these patients.

The Impact of COVID-19 Lockdown on Metabolic Control and Access to Healthcare in People with Diabetes: the CONFI-DIAB Cross-Sectional Study.

INTRODUCTION: The COVID-19 pandemic led to an international health crisis and restrictions. While the phenotype associated with COVID-19 severity in people with diabetes has rapidly been explored, the impact of restrictive measures, including lockdown, and tertiary care disruption on metabolic control and access to healthcare remained unknown. The aim of our study was to provide a comprehensive assessment on the overall management of diabetes during lockdown, including glucose control, weight changes, health care consumption and use of alternative forms of care such as telemedicine services, in a large sample of patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM). METHODS: A prioritization of a care self-administered questionnaire was sent at the end of the first COVID-19 lockdown to all patients with diabetes routinely followed by diabetologists from the University Hospital of Nancy (France). This observational cross-sectional single-center study focused on data from patients with diabetes who returned the questionnaire along with medical records. The primary outcome was the change in HbA1c levels between the 6 months preceding and the 6 weeks following the lockdown. Data are expressed as numbers (%) or medians (quartiles). This study is registered with ClinicalTrials.gov (NCT04485351). RESULTS: We analyzed data from 870 patients with diabetes: 549 T2DM (63.1%), 520 males (59.8%), age 65.0 (57.0, 72.0), body mass index 28.6 (25.1, 32.9) and diabetes duration 20.0 (10.0, 30.0) years. HbA1c levels pre- and post-lockdown were respectively 7.7% (7.1, 8.4) and 7.4% (6.8, 8.2), translating into a significant reduction of - 0.1% (- 0.6, 0.15) (p < 0.0001). Stratified analyses suggested a consistent significant reduction of HbA1c independently of diabetes type. HbA1c reduction was significantly different according to weight changes: - 0.3% (- 0.8, 0.0), - 0.1% (- 0.5, 0.1) and - 0.1% (- 0.5, 0.3) for patients who lost, had stable or gained weight, respectively (p = 0.0029). Respectively, 423 (49.4%) and 790 (92.3%) patients did not consult their general practitioner and diabetologist. Blood tests were undergone by 379 (44.8%) patients, 673 (78.3%) did refill their prescriptions, and 269 (32.1%) used teleconsultation services. CONCLUSIONS: Despite the implementation of a lockdown and disruption in healthcare, no deterioration, rather an improvement, in metabolic control was observed in a large sample of patients with T1DM and T2DM.
