Objective: In male congenital hypogonadotropic hypogonadism (CHH), it was observed that lower dose human gonadotropic hormone (hCG) can maintain normal intratesticular testosterone levels. We propose this study to compare the low-dose hCG, follicle stimulating hormone (FSH), and Testosterone (T) [LFT Regimen] to conventional treatment to induce virilization and fertility.

Design: This open-label randomized pilot study was conducted from June 2020 to December 2021.

Subjects and outcome measures: CHH were randomly assigned to either the LFT regimen (Group A)-low-dose hCG (500U thrice per week), FSH (150U thrice per week), and T(100 mg biweekly) or conventional therapy(GroupB) with high hCG dose(2000U thrice per week) and the same FSH dose. The hCG dosage was titrated to reduce anti-mullerian hormone (AMH) by 50% and normalization of plasma T in groups A and B, respectively. The primary objective was to compare the percentage of individuals who achieved spermatogenesis between the two groups.

Results: Out of 30 patients, 23 (76·7%) subjects achieved spermatogenesis, and the median time was 12 (9-14·9) months. There was no difference in achieving spermatogenesis between the two groups (64·3% vs 7·5%,P = 0·204), and even the median time for spermatogenesis was similar (15months vs 12months,P = 0·248). Both groups had nonsignificant median plasma AMH at spermatogenesis, [6·6 ng/ml (3·3-9·76) vs4·41 ng/ml (2·3-6·47), P = 0·298]. Similarly, the median plasma Inhibin B at spermatogenesis between groups were comparable [152·4 pg/ml (101·7-198·0) vs49·1 pg/ml (128·7-237·3), P = 0·488].

Conclusions: A reasonable approach to induce fertility in male CHH is to initiate combination therapy using FSH, low-dose hCG targeting AMH <6·9 ng/ml, along with T to achieve normal range. Monitoring AMH could serve as a proxy indicator of spermatogenesis.

Objective: The aim of this study was to evaluate the trends in the incidence of diabetic neuropathy (DN) and nondiabetic neuropathy (non-DN) in a hospital-based cohort between 2010 and 2019 in Romania.

Methods: We retrospectively analyzed cases with a primary or secondary discharge International Classification of Diseases, Tenth Revision, diagnosis code of neuropathy reported throughout Romania.

Results: A total of 1 725 729 hospitalizations with a diagnosis of neuropathy (DN, 769 324 - 44.6%, and non-DN, 956 405- 55.4%) were identified. Women accounted for more DN cases (40 0 936- 52.1%), and men accounted for more non-DN cases (63 7 968- 61.0%). The incidence rate showed an increasing trend during the index period, by a mean rate of 4.3%/year for non-DN and 1.4%/year for DN. Type 2 diabetes was responsible for the overall increase in the incidence rate of DN, whereas in type 1 diabetes, the incidence rate decreased; in both types of diabetes, diabetic polyneuropathy was predominant, whereas autonomic neuropathy had an incidence rate of 10 to 20 times lower than polyneuropathy. The incidence rates of non-DNs increased mainly due to inflammatory polyneuropathies (+3.8%) and uremic neuropathy (+10.3%).

Conclusion: Using a nationally representative database of hospital-admitted cases, we found that the incidence rates of DN and non-DN increased from 2010 to 2019. The main contributors were type 2 diabetes, inflammatory polyneuropathy, and uremic neuropathy.

Objective: Automated insulin delivery (AID) systems are a rapidly growing component in the area of continuous subcutaneous insulin infusion (CSII) therapy. As more patients use these systems in the outpatient setting, it is important to assess safety if their use is allowed to continue in the inpatient setting.

Methods: Analysis was conducted of the records of patients using AID technology upon admission to our hospital between June 2020 and December 2022. Adverse events and glycemic control of AID users were compared with patients using non-AID systems and with patients who had CSII discontinued.

Results: There were 185 patients analyzed: 64 on AID, 86 on non-AID, and 35 who had CSII discontinued. The number of patients on AID increased over the course of the observation period, whereas non-AID users decreased. Pairwise comparisons indicated that patient-stay mean glucose levels and percentage of hypoglycemic events were similar between all groups, but the percentage of patient hyperglycemic measurements was significantly lower in the AID cohort. No adverse events (diabetic ketoacidosis, pump site complications, equipment malfunction) were reported in any either CSII cohort.

Conclusion: The type of CSII technology encountered in the hospital is shifting from non-AID toward AID technologies. This analysis supports earlier findings that outpatient AID systems can be successfully transitioned into the inpatient setting. Further study is needed to define if AID systems offer any advantage in glycemic control.

Objective: Mental health has emerged as a worldwide concern given the increasing incidence of anxiety and depression disorders in the last years. Cortisol and sex steroid hormones have been demonstrated to be important regulators of mental health processes in older adults. However, the evidence considering these integrated variables in apparently healthy middle-aged individuals has not been thoroughly addressed. The present study aimed to investigate the association of the plasma cortisol, testosterone, free testosterone, sex hormone-binding globulin (SHBG), and dehydroepiandrosterone sulfate (DHEAS) levels with mental health in middle-aged adults.

Methods: This cross-sectional study included a cohort of 73 middle-aged adults aged 45 to 65 years (women, 53%). Plasma cortisol, testosterone, SHBG, and DHEAS were assessed using a competitive chemiluminescence immunoassay. Free testosterone was calculated from the total testosterone and SHBG. Self-reported depression severity, generic health-related quality of life, hope, satisfaction with life, and optimism-pessimism were evaluated using the Beck Depression Inventory-II (BDI-II), 36-Item Short-Form Health Survey, Adult Hope Scale, Satisfaction with Life Scale, and Life Orientation Test-Revised, respectively-with higher total scores of these scales indicating greater levels of these variables.

Results: The testosterone and free testosterone levels were inversely associated with the BDI-II values in men (all P ≤ .042). The cortisol levels were positively related with the Satisfaction with Life Scale scores, whereas the testosterone, free testosterone, SHBG, and DHEAS levels were negatively correlated with the BDI-II values in women (all P ≤ .045).

Conclusion: In summary, these results suggest that the increased levels of steroid hormones-within the normal values-are associated with better mental health in middle-aged adults.

Objective: Pancreatic neuroendocrine tumors (PNETs) are uncommon tumors which are increasing in incidence. The management of these tumors continues to evolve. This review examines the current role of surgery in the treatment of these tumors.

Methods: Studies published over the past 10 years were identified using several databases including PubMed, MEDLINE, and Science Direct. Search terms included PNETs, treatment, and surgery. Clinical practice guidelines and updates from several major groups were reviewed.

Results: Surgery continues to have a major role in the treatment of sporadic functional and nonfunctional PNETs. Pancreas-sparing approaches are increasingly accepted as alternatives to formal pancreatic resection in selected patients. Options such as watch and wait or endoscopic ablation may be reasonable alternatives to surgery for non-functional PNETs < 2 cm in size. Surgical decision-making in multiple endocrine neoplasia type 1 patients remains complex and in some situations such as gastrinoma quite controversial. The role of surgery has significantly diminished in patients with advanced disease due to the advent of more effective systemic and liver-directed therapies. However, the optimal treatments and sequencing in advanced disease remain poorly defined, and it has been suggested that surgery is underutilized in these patients.

Conclusions: Surgery remains a major treatment modality for PNETs. Given the plethora of available treatments, ongoing controversies and the changing landscape, management has become increasingly complex. An experienced multidisciplinary team which includes surgery is essential to manage these patients.

Objective: This study was designed to develop and validate a predictive model for assessing the risk of thyroid toxicity following treatment with immune checkpoint inhibitors.

Methods: A retrospective analysis was conducted on a cohort of 586 patients diagnosed with malignant tumors who received programmed cell death 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors. The patients were randomly divided into training and validation cohorts in a 7:3 ratio. Logistic regression analyses were performed on the training set to identify risk factors of thyroid dysfunction, and a nomogram was developed based on these findings. Internal validation was performed using K-fold cross-validation on the validation set. The performance of the nomogram was assessed in terms of discrimination and calibration. Additionally, decision curve analysis was utilized to demonstrate the decision efficiency of the model.

Results: Our clinical prediction model consisted of 4 independent predictors of thyroid immune-related adverse events, namely baseline thyrotropin (TSH, OR = 1.427, 95%CI:1.163-1.876), baseline thyroglobulin antibody (TgAb, OR = 1.105, 95%CI:1.035-1.180), baseline thyroid peroxidase antibody (TPOAb, OR = 1.172, 95%CI:1.110-1.237), and baseline platelet count (platelet, OR = 1.004, 95%CI:1.000-1.007). The developed nomogram achieved excellent discrimination with an area under the curve of 0.863 (95%CI: 0.817-0.909) and 0.885 (95%CI: 0.827-0.944) in the training and internal validation cohorts respectively. Calibration curves exhibited a good fit, and the decision curve indicated favorable clinical benefits.

Conclusion: The proposed nomogram serves as an effective and intuitive tool for predicting the risk of thyroid immune-related adverse events, facilitating clinicians making individualized decisions based on patient-specific information.

Objective: Maternal blood lipid and glucose concentrations during pregnancy affect fetal growth and the risk of pregnancy and delivery complications. We aimed to investigate the effects of physical activity (PA) during pregnancy on maternal blood lipid and hemoglobin A1c (HbA1c) concentrations. We hypothesized that higher PA was associated with improved lipid profile and glycemic control.

Methods: In a secondary analysis of a randomized controlled trial, we included 216 pregnant women before week 15 + 0 and tested the effects of two different PA interventions throughout pregnancy compared to standard care on maternal blood lipid and HbA1c concentrations. Additionally, we investigated the effect of PA per se measured by an activity tracker. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, and HbA1c concentrations were measured at week ≤15 + 0, 28+0-6, 34+0-6, and at delivery (week 32 + 1 to 42 + 0). Effects of the interventions and PA per se were tested using linear mixed effects models and linear regression analyses, respectively.

Results: No effects of the PA interventions were detected on maternal lipids or HbA1c during pregnancy. In PA per se analyses, more minutes per week of moderate-to-vigorous intensity PA were associated with less increase in TC (-1.3E-04, P = .020) and LDL-C (-8.5E-05, P = .035) as pregnancy progresses. More active kilocalories were associated with less increase in TC (-5.5E-05, P < .001), HDL-C (-9.5E-06, P = .024), and LDL-C (-3.2E-05, P = .005).

Conclusion: Whilst there were no effects of offering PA interventions, higher PA was associated with reduced increases in TC, HDL-C, and LDL-C as pregnancy progressed.
