Abstract	We investigate the noise in spin transport through a single quantum dot (QD) tunnel coupled to ferromagnetic (FM) electrodes with noncollinear magnetizations. Based on a spin-resolved quantum master equation, auto- and cross-correlations of spin-resolved currents are analyzed to reveal the underlying spin transport dynamics and characteristics for various polarizations. We find the currents of majority and minority spins could be strongly autocorrelated despite uncorrelated charge transfer. The interplay between tunnel coupling and the Coulomb interaction gives rise to an exchange magnetic field, leading to the precession of the accumulated spin in the QD. It strongly suppresses the bunching of spin tunneling events and results in a unique double-peak structure in the noise of the net spin current. The spin autocorrelation is found to be susceptible to magnetization alignments, which may serve as a sensitive tool to measure the magnetization directions between the FM electrodes.

Abstract	AbstractAlthough vaccination with the Coronavirus disease 2019 vaccine is important and effective in the prevention of SARS-CoV-2 infection, the public expressed concerns regarding the adverse effects of vaccine on fertility. Some reviews have focused on it, they have been unable to collect sufficient research data because of the earlier publication period. As relevant evidence has gradually increased, we reviewed these studies from the perspectives of males, females with or without pregnancy, and different vaccine types. The results suggest that although males may experience fluctuations in semen parameters within their physiological ranges after receiving the vaccine, it has not yet reached a level of influence on the partner’s pregnancy probability. As to female without pregnancy, it is believed that vaccination will not affect fertility; however, more research is needed to explore the short-term impact. Vaccination during any trimester is considered safe in pregnant women.

Abstract	Multidimensional health function impairments are common in older patients with chronic kidney disease (CKD). The purpose of this study was to explore whether the risk or severity of geriatric syndrome increased with a decline in renal function. This survey was conducted for CKD patients aged ≥ 60 years and hospitalized at West China Hospital of Sichuan University (Center of Gerontology and Geriatrics, Nephrology, and Endocrinology) and Chengdu Kangfu Kidney Disease Hospital from September 01, 2013 to June 30, 2014. Patients underwent multidimensional individualized assessments by trained doctors. Logistic regression analysis found that the risk of assisted walking (P = 0.001) and urinary incontinence (P = 0.039) increased with a decline in renal function. Regression analysis revealed that the scores of activities of daily living (P = 0.024), nutritional status (P = 0.000), total social support (P = 0.014), and objective support (P = 0.000) decreased with a decline in renal function.

Abstract	BackgroundThe COVID-19 pandemic, caused by SARS-CoV-2, has triggered a global public health crisis of unprecedented proportions. SARS-CoV-2 vaccination is a highly effective strategy for preventing infections and severe COVID-19 outcomes. Although several studies have concluded that COVID-19 vaccines are unlikely to affect fertility, concerns have arisen regarding adverse events, including the potential impact on fertility; these concerns are plagued by limited and inconsistent evidence. ObjectiveThis review aims to provide a recent assessment of the literature on the impact of COVID-19 vaccines on male sperm quality. The possible impact of COVID-19 vaccines on fertility potential was also examined to draw a clearer picture and to evaluate the effects of COVID-19 on male reproductive health. MethodsPubMed, Scopus, Web of Science, Embase, and Cochrane databases were searched from their inception to October 2023. Eligible studies included articles reporting SARS-CoV-2 vaccination and human semen quality and fertility, as well as the impact of vaccination on assisted reproductive technology treatment outcomes. The quality of cohort studies was assessed using the Newcastle-Ottawa Scale, and the quality of cross-sectional studies was assessed using the quality evaluation criteria recommended by the Agency for Healthcare Research and Quality. The systematic review followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. ResultsThe initial literature search yielded 4691 records by searching 5 peer-reviewed databases (PubMed, Scopus, Web of Science, Embase, and Cochrane). Finally, 24 relevant studies were selected for our study. There were evident research inequalities at the regional level, with the United States and Western European countries contributing 38% (9/24) of the studies, Middle Eastern countries contributing 38% (9/24), China accounting for 21% (5/24), and Africa and South America accounting for none. Nonetheless, the overall quality of the included studies was ...

Abstract	Numerous studies have shown the possible contributions of the gut microbiome to the pathogenesis of autism spectrum disorder (ASD). However, recently in Cell, Yap et al. found that autism-related dietary preferences may mediate the ASD-microbiome associations, while the direct associations between ASD and gut microbiota are negligible.

Abstract	Importance: Although sexual function is an indispensable part of overall human health, both male and female sexual dysfunction have been poorly addressed in China. Objective: To explore the self-reported knowledge, attitudes, and practice patterns related to sexual dysfunction among urologists and andrologists in China. Design, setting, and participants: This survey study enrolled urologists and andrologists from various regions in China. Urologists and andrologists from 100 selected medical centers were invited to participate in the survey. Responses from eligible urologists and andrologists were analyzed from July 20 to 30, 2022. Main outcomes and measures: The primary outcomes were the respondents' basic characteristics and knowledge, attitudes, and practice patterns related to sexual dysfunction for both male and female patients. Results: Among 1687 urologists and andrologists (749 [98.7%] male; 375 participants [49.4%] aged 36-50 years) invited to participate, 759 were eligible, with 395 participants (52.0%) determined to have passing knowledge on diagnosis and treatment for male and female sexual dysfunction (defined as a score of 6 or more points) and 523 participants (68.9%) responding with positive attitudes, including interested in providing sex counseling and managing sexual issues for male and female patients. Moreover, of 395 individuals with passing knowledge, 289 participants (73.2%) were interested in providing sex counseling or sexual function care to patients; 336 participants (85.1%) thought they should routinely screen the spouse for sexual dysfunction when the partner was diagnosed with a sexual dysfunction. Among individuals with passing knowledge, 232 participants (58.7%) reported knowledge on the guidelines for diagnosis and treatment of premature ejaculation and 162 participants (41.0%) reported knowledge on the guidelines for the diagnosis and treatment of erectile dysfunction, which were significantly higher than rates among 364 participants with limited knowledge (premature ejaculation: 140 participants [38.5%]; erectile dysfunction: 78 participants [21.4%]). Only a few urologists and andrologists could manage female sexual dysfunction following guidelines, although the proportions were higher in the group with passing knowledge (38 participants [9.6%]) compared with those with less knowledge (5 participants [1.4%]). Additionally, most participants felt confident to manage male sexual issues (569 participants [75.0%] reporting often or almost always), while most of them were not so confident on female sexual issues (274 participants [36.1%] reporting often or almost always), mainly due to lacking knowledge in this field (518 participants [68.2%]). Conclusions and relevance: The findings of this survey study suggest that urologists and andrologists in China lacked knowledge on sexual dysfunction, which in turn was associated with their attitudes and clinical practice patterns, especially for female sexual dysfunction. More training on sexual dysfunction should be undertaken to improve this situation.

Abstract	Background: The COVID-19 pandemic, caused by SARS-CoV-2, has triggered a global public health crisis of unprecedented proportions. SARS-CoV-2 vaccination is a highly effective strategy for preventing infections and severe COVID-19 outcomes. Although several studies have concluded that COVID-19 vaccines are unlikely to affect fertility, concerns have arisen regarding adverse events, including the potential impact on fertility; these concerns are plagued by limited and inconsistent evidence. Objective: This review aims to provide a recent assessment of the literature on the impact of COVID-19 vaccines on male sperm quality. The possible impact of COVID-19 vaccines on fertility potential was also examined to draw a clearer picture and to evaluate the effects of COVID-19 on male reproductive health. Methods: PubMed, Scopus, Web of Science, Embase, and Cochrane databases were searched from their inception to October 2023.

The quality of cohort studies was assessed using the Newcastle-Ottawa Scale, and the quality of cross-sectional studies was assessed using the quality evaluation criteria recommended by the Agency for Healthcare Research and Quality. The systematic review followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: The initial literature search yielded 4691 records by searching 5 peer-reviewed databases (PubMed, Scopus, Web of Science, Embase, and Cochrane). Finally, 24 relevant studies were selected for our study. There were evident research inequalities at the regional level, with the United States and Western European countries contributing 38% (9/24) of the studies, Middle Eastern countries contributing 38% (9/24), China accounting for 21% (5/24), and Africa and South America accounting for none. Nonetheless, the overall quality of the included studies was generally good. Our results demonstrated that serious side effects of the COVID-19 vaccine are extremely rare, and men experience few problems with sperm parameters or reproductive potential after vaccination. Conclusions: On the basis of the studies published so far, the COVID-19 vaccine is safe for male reproductive health. Obviously, vaccination is a wise option rather than experience serious adverse symptoms of viral infections. These instances of evidence may help reduce vaccine hesitancy and increase vaccination coverage, particularly among reproductive-age couples. As new controlled trials and prospective cohort studies with larger sample sizes emerge, the possibility of a negative effect of the COVID-19 vaccine on sperm quality must be further clarified.
