Sex differences in children's cognitive functions and phthalates exposure: a meta-analysis.

BACKGROUND: Phthalates exposure might affect children's intelligence development. This study aimed to determine (1) whether sex and age affect cognitive function and (2) whether sex differences in cognitive performance are wider with higher phthalate concentrations. METHODS: Data were collected from PubMed (1998-2022), PROQUEST (1997-2022), and SpringerLink (1995-2022). The study followed the PRISMA process. The included articles were followed by PECO framework. The GRADE applied to assess the certainty of evidence. Of 2422 articles obtained, nine were selected using inclusion criteria. The random-effects model was used to estimate the pooled effects. RESULTS: Our meta-regression indicated a significant difference between sex differences with age at phthalate concentration assessment (ß = -0.25; 95% CI = -0.47, -0.03) and MEHP concentration (ß = -0.20; 95% CI = -0.37, -0.03). CONCLUSIONS: The limitation of the current article is it only provides information on intelligence level rather than other aspects of cognitive function. Thus, the sequelae of phthalate exposure on attention and executive function are still unclear. Our analysis shows significant difference between sex differences in cognitive function scores associated with age at phthalate concentration assessment. Girls might be more resilient in cognitive function at a younger age or during lower concentrations of phthalates metabolites. IMPACT: This is the first meta-analysis to evaluate the pooled estimates of sex differences in objective cognitive functions among children with phthalate exposure. The female might be a protective factor when exposed to toxic plasticizers while the concentration is low. This study captures the possible role of sex in cognitive functioning and plasticizer exposure through a meta-analysis of children's sex, cognitive scores, and plasticizer exposure.

Discovery of new genetic loci for male sexual orientation in Han population.

Epidemiological studies have demonstrated that the genetic factors partly influence the development of same-sex sexual behavior, but most genetic studies have focused on people of primarily European ancestry, potentially missing important biological insights. Here, we performed a two-stage genome-wide association study (GWAS) with a total sample of 1478 homosexual males and 3313 heterosexual males in Han Chinese populations and identified two genetic loci (rs17320865, Xq27.3, FMR1NB, Pmeta = 8.36 × 10-8, OR = 1.29; rs7259428, 19q12, ZNF536, Pmeta = 7.58 × 10-8, OR = 0.75) showing consistent association with male sexual orientation. A fixed-effect meta-analysis including individuals of Han Chinese (n = 4791) and European ancestries (n = 408,995) revealed 3 genome-wide significant loci of same-sex sexual behavior (rs9677294, 2p22.1, SLC8A1, Pmeta = 1.95 × 10-8; rs2414487, 15q21.3, LOC145783, Pmeta = 4.53 × 10-9; rs2106525, 7q31.1, MDFIC, Pmeta = 6.24 × 10-9). These findings may provide new insights into the genetic basis of male sexual orientation from a wider population scope. Furthermore, we defined the average ZNF536-immunoreactivity (ZNF536-ir) concentration in the suprachiasmatic nucleus (SCN) as lower in homosexual individuals than in heterosexual individuals (0.011 ± 0.001 vs 0.021 ± 0.004, P = 0.013) in a postmortem study. In addition, compared with heterosexuals, the percentage of ZNF536 stained area in the SCN was also smaller in the homosexuals (0.075 ± 0.040 vs 0.137 ± 0.103, P = 0.043). More homosexual preference was observed in FMR1NB-knockout mice and we also found significant differences in the expression of serotonin, dopamine, and inflammation pathways that were reported to be related to sexual orientation when comparing CRISPR-mediated FMR1NB knockout mice to matched wild-type target C57 male mice.

Interpersonal psychotherapy-based psychological intervention for patient suffering from COVID-19: A case report.

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) was first found in Wuhan, China, and it has rapidly spread worldwide since the end of 2019. There is an urgent need to treat the physical and psychological aspects of COVID-19. Interpersonal psychotherapy (IPT)-based psychological intervention is an evidence-based therapy for depression and post-traumatic stress disorder. CASE SUMMARY: This report describes a case of COVID-19 in a patient who transmitted the disease to his entire family. The patient received four sessions of IPT-based psychological intervention. We used the Hamilton Rating Scale for Depression and Patient Health Questionnaire to measure depression level, and the Hamilton Anxiety Scale and Generalized Anxiety Disorder to measure anxiety among the patients. CONCLUSION: This case shows that IPT-based therapy can reduce COVID-19 patient depression and anxiety and the advantage of IPT-based therapy.

Executive function and its relation to anatomical connectome in homosexual and heterosexual men.

BACKGROUND: Sexual orientation has been suggested to affect executive function, of which the neurobiological basis is still largely unknown. In this study, we explored the interrelationship between neuropsychological characteristics in homosexual and heterosexual men and their anatomical connectome by graph theoretical analysis. METHODS: Fifty-three homosexual and 47 heterosexual males underwent diffusion tensor magnetic resonance imaging (MRI) and neuropsychological assessments. Whole-brain anatomical networks were constructed using white matter tractography, performed on the diffusion tensor imaging data. Neuropsychological tests included the Wisconsin Card Sorting Test (WCST), the Continuous Performance Test (CPT) and the Trail-Making Test (TMT). RESULTS: The cognitive performance of homosexual men was significantly poorer than their heterosexual counterparts in terms of WCST total correct responses. Anatomical connectome analysis revealed a lower (P=0.001) anatomical connectivity between left PoCG and left SMG (P=0.003) in homosexual men as compared to heterosexual men. Linear regression analyses showed that the WCST total correct responses score was significantly linked with sexual orientation (P=0.001). The anatomical connectivity strength between left PoCG and left SMG was also shown to be significantly correlated with sexual orientation (P=0.039) and education (P=0.047). CONCLUSIONS: Our study demonstrated the differences in the performance of WCST and anatomical connectome of large-scale brain networks between homosexual and heterosexual men, extending our understanding of the brain's circuitry and the characteristics of executive function in men of different sexual orientation.

Dialectical behavior therapy-based psychological intervention for woman in late pregnancy and early postpartum suffering from COVID-19: a case report.

At the end of 2019, a new form of pneumonia disease known as the corona virus disease 2019 (COVID-19) rapidly spread throughout most provinces of China, and the total global number of COVID-19 cases has surpassed 500 000 by Mar. 27, 2020 (WHO, 2020). On Jan. 30, 2020, the World Health Organization (WHO) declared COVID-19 a global health emergency (WHO, 2020). COVID-19 causes most damage to the respiratory system, leading to pneumonia or breathing difficulties. The confirmed case fatality risk (cCFR) was estimated to be 5% to 8% (Jung et al., 2020). Besides physical pain, COVID-19 also induces psychological distress, with depression, anxiety, and stress affecting the general population, quarantined population, medical staff, and patients at different levels (Kang et al., 2020; Xiang et al., 2020). Previous research on patients in isolation wards highlighted the risk of depressed mood, fear, loneliness, frustration, excessive worries, and insomnia (Abad et al., 2010).

Efficacy of internet-based integrated intervention on depression and anxiety symptoms in patients with COVID-19.

Public health crises, such as the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since Dec. 2019, are widely acknowledged as severe traumatic events that impose threats not only because of physical concerns but also because of the psychological distress of infected patients. We designed an internet-based integrated intervention and evaluated its efficacy on depression and anxiety symptoms in patients infected by SARS-CoV-2.

Circulating T lymphocyte subsets, cytokines, and immune checkpoint inhibitors in patients with bipolar II or major depression: a preliminary study.

This study aimed to investigate the less known activation pattern of T lymphocyte populations and immune checkpoint inhibitors on immunocytes in patients with bipolar II disorder depression (BD) or major depression (MD). A total of 23 patients with BD, 22 patients with MD, and 20 healthy controls (HCs) were recruited. The blood cell count of T lymphocyte subsets and the plasma level of cytokines (IL-2, IL-4, IL-6, IL-10, TNF-α, and IFN-γ) were selectively investigated. The expression of T-cell immunoglobulin and mucin-domain containing-3 (TIM-3), programmed cell death protein 1 (PD-1) and its ligands, PD-L1 and PD-L2, on T lymphocytes and monocytes, was detected. In results, blood proportion of cytotoxic T cells significantly decreased in BD patients than in either MD patients or HCs. The plasma level of IL-6 increased in patients with BD and MD. The expression of TIM-3 on cytotoxic T cells significantly increased, whereas the expression of PD-L2 on monocytes significantly decreased in patients with BD than in HCs. These findings extended our knowledge of the immune dysfunction in patients with affective disorders.

Efficacy of repetitive transcranial magnetic stimulation with quetiapine in treating bipolar II depression: a randomized, double-blinded, control study.

The clinical and cognitive responses to repetitive transcranial magnetic stimulation (rTMS) in bipolar II depressed patients remain unclear. In this study, thirty-eight bipolar II depressed patients were randomly assigned into three groups: (i) left high-frequency (n = 12), (ii) right low-frequency (n = 13), (iii) sham stimulation (n = 13), and underwent four-week rTMS with quetiapine concomitantly. Clinical efficacy was evaluated at baseline and weekly intervals using the 17-item Hamilton Depression Rating Scale (HDRS-17) and Montgomery-Asberg Depression Rating Scale (MADRS). Cognitive functioning was assessed before and after the study with the Wisconsin Card Sorting Test (WCST), Stroop Word-Color Interference Test (Stroop), and Trail Making Test (TMT). Thirty-five patients were included in the final analysis. Overall, the mean scores of both the HDRS-17 and the MADRS significantly decreased over the 4-week trial, which did not differ among the three groups. Exploratory analyses revealed no differences in factor scores of HDRS-17s, or in response or remission rates. Scores of WCST, Stroop, or TMT did not differ across the three groups. These findings indicated active rTMS combined with quetiapine was not superior to quetiapine monotherapy in improving depressive symptoms or cognitive performance in patients with bipolar II depression.

Changes of plasma B-type natriuretic peptide levels after high-pressure post-dilation following coronary stent deployment.

OBJECTIVE: To evaluate the changes of plasma B-type natriuretic peptide(BNP) levels after high-pressure post-dilation following coronary stent deployment. METHODS: A total of 173 patients undergoing percutaneous coronary intervention for the left anterior descending artery were enrolled into the study. All patients were divided into two groups: the conventional group and the post-dilation group. The plasma BNP, troponin I(TnI), myocardial band isoenzyme of creatine kinase(CK-MB) levels and the serum high sensitive C-reactive protein(hs-CRP) levels immediately before and 24 hours after the interventional procedures were compared between the two groups. RESULTS: There were no significant differences between the two groups in terms of clinical features, clinical and biochemical parameters, stent parameters, pre-procedural plasma BNP and TnI levels, pre-procedural serum hs-CRP levels, as well as pre- and post-procedural CK-MB levels (all P>0.05). In the conventional group, post-procedural plasma BNP levels were significantly reduced when compared with the pre-procedural levels, median(25th,75th) were 32.5 ng/L(15.0,52.4) vs. 37.7 ng/L(18.2,67.3), P = 0.001. In the post-dilation group, post-procedural plasma BNP levels were significantly increased when compared with the pre-procedural levels, median(25th,75th) were 53.5 ng/L(29.6,82.8) vs. 44.2 ng/L(17.15,70.7), P<0.0001. Post-procedural plasma TnI levels were also significantly increased when compared with the pre-procedural levels in both groups, median(25th,75th) were 0.02 ng/L(0.01,0.08) vs. 0.01 ng/L(0.01,0.01), 0.05 ng/L(0.01,0.35) vs. 0.01 ng/L(0.01,0.01), respectively, P<0.0001, so were the serum hs-CRP levels, median(25th,75th) were 3.3 mg/L(2.4,4.7) vs. 2.2 mg/L(1.4,3.3), 4.2 mg/L(3.175,5.825) vs. 2.3 mg/L(1.45,3.6), respectively, P<0.0001. Post-procedural plasma BNP, TnI and serum hs-CRP levels in the post-dilation group were significantly higher than those in the conventional group(all P<0.0001). CONCLUSION: High-pressure post-dilation following coronary stent deployment resulted in a significant increase of plasma BNP levels, as well as plasma TnI levels and serum hs-CRP levels, which may be related to myocardial perfusion, more myocardial injury and more inflammation.

[Serum parathyroid hormone levels predict hospitalization in outpatients of heart failure: a preliminary study].

OBJECTIVE: To evaluate the predicative value of serum parathyroid hormone (PTH) levels in outpatients of heart failure (HF) for hospitalization. METHODS: A total of 102 consecutive HF outpatients were enrolled. The receiver operating characteristic (ROC) curves demonstrated the optimal cut-off points of PTH levels for hospitalization due to HF. And Logistic regression analysis model was employed to analyze the independent association between PTH and hospitalization for HF. RESULTS: The more advanced grade of New York Heart Association (NYHA), the higher serum level of PTH. The ROC curves showed PTH levels ≥ 56.05 ng/L were the optimal cut-off point for hospitalization for HF with a sensitivity of 90.0%, a specificity of 89.2% and the area under ROC curve of 0.92. After adjustment for predictors for hospitalization due to HF (gender, age, diabetes mellitus, hypertension, left ventricular ejection fraction, estimated glomerular filtration rate and brain natriuretic peptide), PTH levels were associated with hospitalization due to HF (OR = 1.282, 95%CI 1.026-1.362). CONCLUSION: The serum level of PTH in HF outpatients is an independent predicator for hospitalization due to HF.

Percutaneous valved stent implantation in the ascending aorta for the treatment of very high-risk aortic regurgitation: an animal study.

PURPOSE: We investigated the effects of percutaneous valved stent implantation in the ascending aorta as an alternative treatment for aortic regurgitation in a canine model. MATERIALS AND METHODS: A total of 16 healthy dogs weighing an average of 18.3 ± 2.1 kg were used for the establishment of animal models of chronic aortic regurgitation by percutaneous aortic valve perforation and balloon dilation. At 2 mo after successful model establishment, all experimental animals underwent valved stent implantation in the ascending aorta and then were followed up for 3 mo. RESULTS: Experimental models of chronic aortic regurgitation were successfully established in 10 dogs. Surviving dogs underwent successful valved stent implantation in the ascending aorta and were subsequently followed up for 3 mo. The level of instantaneous aortic regurgitation at 3-mo follow-up was significantly reduced compared with that before valved stent implantation (2.4 ± 0.9 versus 10.6 ± 2.1 mL/s, P < 0.05). The left ventricular ejection fraction was significantly increased (53.8 ± 4.2% versus 37.8 ± 3.7%, P < 0.05), and the left ventricular end-diastolic volume was also significantly reduced (30.3 ± 2.2 versus 40.1 ± 3.6 mL, P < 0.05). No paravalvular leak, stroke, atrioventricular block, or other complications occurred in dogs undergoing valved stent implantation. CONCLUSIONS: Percutaneous valved stent implantation in the ascending aorta is feasible, effective, and safe as an alternative treatment for very high-risk aortic regurgitation in a canine model.
