Purpose: Coronavirus disease 2019 (COVID-19) infection may affect serum hormones levels and male sexual function. This study aims to provide evidence for the causal relationship between COVID-19 infection, serum testosterone levels and the risk of erectile dysfunction (ED) using a two-sample Mendelian randomization (MR) approach. Materials and Methods: Summary-level data for serum testosterone levels (199,569 samples and 12,321,875 single nucleotide polymorphisms [SNPs]) were obtained from Rebecca’s study, while data for ED (6,175 cases and 217,630 controls) were sourced from Bovijn’s study. Genetic variations linked to COVID-19 were used as instrumental variables (IVs) in meta-analyses of genome-wide association studies (GWASs) involving 6,406 cases and 902,088 controls from the COVID-19 Host Genetics Initiative.The inverse-variance weighted (IVW) method was primarily employed to evaluate the potential associations between COVID-19 infection, serum testosterone levels, and the risk of ED. The weighted mode, weighted-median and simple-median method were employed to evaluate the sensitivity. Heterogeneity and pleiotropic outlier were assessed using Cochran’s Q test and MREgger regression. Results: The MR analysis demonstrated that COVID-19 infection was associated with reduced serum testosterone levels (odds ratio [OR] 0.966, 95% confidence interval [CI] 0.938–0.993, p=0.016) and an increased risk of ED (OR 1.205, 95% CI 1.063–1.367, p=0.004) when using IVW methods. Sensitivity analyses utilizing various IV sets and MR approach remained consistent. Conclusions COVID-19 infection is associated with a decrease in serum testosterone levels and an increased risk of ED. Male patients recovering from COVID-19 need to pay special attention to their sex hormone levels and sexual health.

Objective:To explore the relationship between family cohesion and suicide tendency among gradu-ate student and the role of resilience and coping style between them.Methods:A total of 3 945 graduate students were assessed with the Adolescents'Suicide Tendency(AST),Family Environment Scale(FES),Connor-David-sonResilience Scale(CD-RISC),and Trait Coping Style Questionnaire(TCSQ).The mediating effect of resilience and the moderating effect of positive coping style were examined by using latent moderate structural equations.Results:The degree of AST was negatively associated with the family cohesion scores(β=-0.22).The scores of CD-RISC played a partial mediating role between the scores of family cohesion and AST,and the media-ting effect was-3.92(95％CI:-4.44--3.41),the mediating effect accounted for 43.41％of the total effect.The scores of positive coping style played a moderating role in the relationship between the scores of gradu-ate student'AST and family cohesion(β=0.06).Conclusion:The suicide tendency of graduate students may be related to family cohesion,resilience and positive coping style.

Objective:To investigate the distribution of pathological types of unilateral primary aldosteronism, and to explore the clinical characteristics and prognosis of patients with different pathological types.Methods:A total of 241 patients with unilateral primary aldosteronism who underwent adrenal surgery were included in this study. The clinical data and postoperative follow-up data were collected, and the postoperative tissue sections were stained with HE and aldosterone synthase. According to the staining results, pathological types of 241 patients were classified, and the clinical characteristics and surgical prognosis of patients with unilateral primary aldosteronism were compared.Results:According to the international histopathology consensus for unilateral primary aldosteronism, among 241 patients with unilateral primary aldosteronism, 223 were classical(92.5%), 17 were non-classical(7.1%), and 1 was aldosterone producing carcinoma(0.4%). Among classical cases, 189 were aldosterone producing adenoma and 34 were aldosterone producing nodule. In the non-classical cases, 8 cases were multiple aldosterone producing nodule and 9 cases were multiple aldosterone producing nodule. Compared with the classical group, the non-classical group had a longer duration of hypertension(9.0 vs 5.0 years, P=0.062) and a lower baseline plasma aldosterone concentration(273 vs 305 pg/mL, P=0.147), but the difference was not significant. There was no significant difference between the two groups in the proportion of patients who achieved a complete biochemical response after surgery(98% vs 92.3%, P=0.281), but the proportion of patients who achieved a complete clinical response was significantly lower in the non-classical group(23.1% vs 52.9%, P=0.046). Conclusion:The pathological types of unilateral primary aldosteronism are predominantly classical, with aldosterone-producing adenoma being the most common. There were no significant differences in the clinical characteristics and postoperative biochemical remission rates between classical and non-classical patients, but the clinical prognosis of the latter was inferior to the former.

Objective:To evaluate postoperative biochemical and clinical remission rates in patients with unilateral primary aldosteronism and analyze related influencing factors.Methods:A total of 406 patients of primary aldosteronism with confirmed subtyping, who underwent adrenalectomy and completed follow-up in the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to March 2022 were retrospectively enrolled. Clinical and biochemical data were recorded. Postoperative clinical and biochemical outcomes were assessed according to Primary Aldosteronism Surgery Outcome(PASO) consensus.Results:Complete biochemical success was achieved in 391(96.31%) of 406 primary aldosteronism patients, while partial and absent biochemical success in only 4(0.99%) and 11(2.71%) primary aldosteronism patients; Complete clinical success was seen in 217(53.45%) patients, and partial clinical success in 189(46.55%) patients. Compared to the partial clinical success group, the complete clinical success group was younger, had a greater proportion of women, a smaller body mass index, a shorter duration of hypertension, a smaller daily defined dose value for antihypertensive medication, a higher estimated glomerular filtration rate(eGFR), and a lower proportion of family history of hypertension and diabetes mellitus. Multifactorial logistic regression analysis further showed that gender( OR=2.49, 95% CI 1.42-4.35, P=0.001), body mass index( OR=1.16, 95% CI 1.05-1.28, P=0.003), antihypertensive drug daily defined dose( OR=1.83, 95% CI 1.37-2.44, P<0.001), family history of hypertension( OR=2.16, 95% CI 1.22-3.83, P=0.008), history of diabetes( OR=2.47, 95% CI 1.15-5.29, P=0.021), and eGFR( OR=0.98, 95% CI 0.97-0.99, P=0.001) were independent factors influencing clinical prognosis of primary aldosteronism. Conclusion:The postoperative complete biochemical success is higher in patients with unilateral primary aldosteronism, but only about half of all patients achieve complete clinical success.

Objective:To investigate the appropriate cut-off for diagnosis of primary aldosteronism (PA) by seated saline suppression test (SSST) based on liquid chromatography with tandem mass spectrometry (LC-MS/MS).Methods:In this cross-sectional study, patients who underwent SSST for suspected PA in the First Affiliated Hospital of Chongqing Medical University from January 2018 to March 2022 were evaluated. Briefly, 300 patients with PA and 119 with essential hypertension (EH) were included. Plasma aldosterone concentration (PAC) after SSST was determined by LC-MS/MS. Primary aldosteronism confirmatory testing (PACT) score was used as the reference standard for diagnosis of PA, and receiver operating characteristic (ROC) curve was used to explore the cut-off value.Results:The average age of the PA group was (50.8±10.5) years, and males accounted for 53.00% ( n=159); the average age of the EH group was (49.4±11.2) years, and males accounted for 26.89% ( n=32). The area under the ROC curve of PAC post-SSST was 0.819 (95% CI 0.775-0.862). When 40 pg/ml (110.8 pmol/L) was selected as the appropriate cut-off for diagnosis of PA, the sensitivity was 83.67% (95% CI 78.88%-87.56%) and specificity was 60.50% (95% CI 51.10%-69.21%). Thus, 95.09% (155/163) of patients with unilateral PA could be identified. Conclusion:PAC after SSST determined by LC-MS/MS has high efficacy for diagnosis of PA, and 40 pg/ml is recommended as the appropriate cut-off value.

Objective:To analyze the clinical characteristics and prognosis of patients with primary aldosteronism (PA) associated with subclinical Cushing syndrome (SCS).Methods:This retrospective cohort study was conducted at the First Affiliated Hospital of Chongqing Medical University in China. Patients with PA were included between January 2014 and December 2022. According to the results of 1-mg overnight dexamethasone suppression test, the patients were divided into the PA group and PA associated with SCS (PA/SCS) group. The demographic information, hormone levels, and follow-up results were analyzed. Independent sample t-test, chi-square test and Mann-Whitney U test were used for data comparison. Results:A total of 489 PA patients were enrolled in this study, of which 109 had PA/SCS (22.3%). Patients with SCS were on average older (54.4±10.7 vs . 47.4±11.0, P<0.001); had a larger proportion of women (69.7%, 76/109 vs . 57.4%, 218/380; P=0.020); and a longer duration of hypertension [96 (36, 180) vs . 60 (12, 120) months, P=0.001] than patients without SCS. There were 215 and 51 patients in the PA group and PA/SCS group, who completed adrenalectomy and follow-up, respectively. The remission rate of autonomous cortisol secretion in the PA/SCS group was 85.3% (29/34). There was no significant difference in the remission rate of autonomous aldosterone secretion among patients between the PA/SCS and PA group (94.1%, 48/51 vs. 94.4%, 203/215; P=1.000), while the clinical remission rate in the PA/SCS group was lower than that in the PA group (39.2%, 20/51 vs. 61.9%, 133/215; P=0.003). Conclusions:SCS is common in PA patients (22.3%), and the clinical remission rate is low. Screening using the 1-mg overnight dexamethasone suppression test is recommended for all patients with PA.

Objective:To analyze the distribution characteristics of plasma renin concentration (PRC) in patients with aldosterone-producing adenoma (APA) and its impact on diagnosis.Methods:In this retrospective case series, clinical data from 200 patients with APA (80 men and 120 women; mean age 45.6 years) in the First Affiliated Hospital of Chongqing Medical University from November 2013 to January 2022 were evaluated. PRC was determined by automated chemiluminescence immunoassay. The distribution characteristics of PRC were analyzed, and 8.2 mU/L was used as the low renin cutoff to evaluate whether renin was suppressed.Results:The median PRC was 1.6 mU/L (range, 0.4-41.5 mU/L). There were 116 patients with APA with PRC of ≤2 mU/L, 41 patients with 28.2 mU/L) in 8.0% (16/200) of the patients with APA. And PRC was not suppressed in 2.5% (5/200) of the patients with APA, resulting in a primary aldosteronism negative screening outcome.Conclusions:Although most patients with APA have low PRC, there are a small number (8%) of patients whose PRC has not been fully suppressed, which can lead to missed diagnoses during primary aldosteronism screening. While primary aldosteronism is highly suspected, further investigations are required to determine the diagnosis, even if PRC is not fully suppressed at screening.

Primary aldosteronism(PA) is one of the most common secondary hypertension, the pathogenesis is still not fully understood. Aldosterone synthase(CYP11B2) was thought to be continuously expressed in the zona glomerulosa of the adrenal cortex. In recent years, it is found that there were discontinuous CYP11B2 positive cell clusters in adrenal cortex via immunohistochemical staining, and proposed the concept of aldosterone-producing cell clusters(APCC). Thenceforwarding a growing body of studies suggest that there may be a potential causal link between APCC and PA. This article summarizes the latest studies on APCC and provide an update on the potential role of APCC in the pathogenesis of PA.

Objective:The aim of the present study was to re-evaluate the diagnostic value and optimal cutoff point of captopril challenge test (CCT) in diagnosis of primary aldosteronism (PA).Methods:This is a retrospective study. All patients with a high risk for PA underwent screening test, and then proceeded to CCT and fludrocortisone suppression test (FST) on different days. The FST was used as a reference standard for PA. The plasma renin concentration (PRC) and plasma aldosterone concentration (PAC) were measured with an automated chemiluminescence immunoassay. Random number method was performed in the patients with unilateral primary aldosteronism (UPA), in order to make the proportion of the analyzed UPA in PA was 35%. Receiver operating characteristic (ROC) analyses were performed to compare diagnostic accuracy.Results:A total of 543 patients with 400 PA patients and 143 essential hypertension (EH) patients were enrolled. The diagnostic value of post-CCT PAC was significantly higher than that of the post-CCT plasma aldosterone-renin ratio (ARR), and that of the PAC suppression percentage, respectively. The area under the ROC curve (AUC ROC) was 0.86 (0.83, 0.89) for PAC, 0.78 (0.74, 0.82) for ARR, and 0.62 (0.56, 0.67) for the PAC suppression percentage (all P<0.01), respectively. The optimal cutoff point of post-CCT PAC for PA was 110 ng/L, in which the sensitivity and specificity were 73.25% and 79.02%, respectively. The diagnostic efficiency of post-CCT PAC was not improved either in combination with PAC suppression percentage or in combination with post-CCT ARR. Conclusions:CCT is a useful test for the confirmation of PA. PAC level of 110 ng/L at 2 h after 50 mg of captopril is recommended as an optimal cutoff point for the diagnosis of PA.

Primary aldosteronism (PA) is a kind of disease caused by excessive aldosterone secretion from the adrenal cortex, the reason of which include bilateral adrenal hyperplasia, aldosteronoma, unilateral adrenal hyperplasia, etc. Surgical treatment is the first choice for unilateral adrenal lesions. In this article, we report a patient who underwent left adrenal surgery but did not achieve the expected results. This case suggests that clinicians need to further improve the level of diagnosis and treatment of primary aldosteronism, especially the surgical methods.
