Efficacy of Voluntary Medical Male Circumcision to Prevent HIV Infection Among Men Who Have Sex With Men : A Randomized Controlled Trial.

BACKGROUND: Observational studies suggest that voluntary medical male circumcision (VMMC) may lower HIV risk among men who have sex with men (MSM). A randomized controlled trial (RCT) is needed to confirm this. OBJECTIVE: To assess the efficacy of VMMC in preventing incident HIV infection among MSM. DESIGN: An RCT with up to 12 months of follow-up. (Chinese Clinical Trial Registry: ChiCTR2000039436). SETTING: 8 cities in China. PARTICIPANTS: Uncircumcised, HIV-seronegative men aged 18 to 49 years who self-reported predominantly practicing insertive anal intercourse and had 2 or more male sex partners in the past 6 months. INTERVENTION: VMMC. MEASUREMENTS: Rapid testing for HIV was done at baseline and at 3, 6, 9, and 12 months. Behavioral questionnaires and other tests for sexually transmitted infections were done at baseline, 6 months, and 12 months. The primary outcome was HIV seroconversion using an intention-to-treat analysis. RESULTS: The study enrolled 124 men in the intervention group and 123 in the control group, who contributed 120.7 and 123.1 person-years of observation, respectively. There were 0 seroconversions in the intervention group (0 infections [95% CI, 0.0 to 3.1 infections] per 100 person-years) and 5 seroconversions in the control group (4.1 infections [CI, 1.3 to 9.5 infections] per 100 person-years). The HIV hazard ratio was 0.09 (CI, 0.00 to 0.81; P = 0.029), and the HIV incidence was lower in the intervention group (log-rank P = 0.025). The incidence rates of syphilis, herpes simplex virus type 2, and penile human papillomavirus were not statistically significantly different between the 2 groups. There was no evidence of HIV risk compensation. LIMITATION: Few HIV seroconversions and limited follow-up period. CONCLUSION: Among MSM who predominantly practice insertive anal intercourse, VMMC is efficacious in preventing incident HIV infection; MSM should be included in VMMC guidelines.

Knowledge, attitude, practice, needs, and implementation status of intensive care unit staff toward continuous renal replacement therapy: a survey of 66 hospitals in central and South China.

BACKGROUND: Continuous renal replacement therapy (CRRT) is a commonly utilized form of renal replacement therapy (RRT) in the intensive care unit (ICU). A specialized CRRT team (SCT, composed of physicians and nurses) engage playing pivotal roles in administering CRRT, but there is paucity of evidence-based research on joint training and management strategies. This study armed to evaluate the knowledge, attitude, and practice (KAP) of ICU staff toward CRRT, and to identify education pathways, needs, and the current status of CRRT implementation. METHODS: This study was performed from February 6 to March 20, 2023. A self-made structured questionnaire was used for data collection. Descriptive statistics, T-tests, Analysis of variance (ANOVA), multiple linear regression, and Pearson correlation coefficient tests (α = 0.05) were employed. RESULTS: A total of 405 ICU staff from 66 hospitals in Central and South China participated in this study, yielding 395 valid questionnaires. The mean knowledge score was 51.46 ± 5.96 (61.8% scored highly). The mean attitude score was 58.71 ± 2.19 (73.9% scored highly). The mean practice score was 18.15 ± 0.98 (85.1% scored highly). Multiple linear regression analysis indicated that gender, age, years of CRRT practice, ICU category, and CRRT specialist panel membership independently affected the knowledge score; Educational level, years of CRRT practice, and CRRT specialist panel membership independently affected the attitude score; Education level and teaching hospital employment independently affected the practice score. The most effective method for ICU staff to undergo training and daily work experience is within the department. CONCLUSION: ICU staff exhibit good knowledge, a positive attitude and appropriately practiced CRRT. Extended CRRT practice time in CRRT, further training in a general ICU or teaching hospital, joining a CRRT specialist panel, and upgraded education can improve CRRT professional level. Considering the convenience of training programs will enhance ICU staff participation. Training should focus on basic CRRT principles, liquid management, and alarm handling.

[Linderae Radix water extract treats diarrhea-predominant irritable bowel syndrome in rats: a serum metabolomics study].

This study aims to investigate the mechanism of Linderae Radix water extract(LRWE) in the prevention and treatment of diarrhea-predominant irritable bowel syndrome(IBS-D) based on serum metabolomics. Eighteen 2-week-old male SD rats were randomized into control, IBS-D model, and LRWE groups. The rats in other groups except the control group received gavage of senna concentrate combined with restraint stress for the modeling of IBS-D. The rats in the LRWE group were administrated with LRWE(5.4 g·kg~(-1)) by gavage, and those in the control and IBS-D model groups with an equal volume of distilled water for a total of 14 days. The visceral sensitivity was evaluated by the abdominal withdrawal reflex(AWR) score, and the degree of diarrhea was assessed by the fecal water content(FWC). The morphological changes of the colon and the morphology and number of goblet cells were observed by hematoxylin-eosin(HE) and periodic acid-schiff(PAS) staining, respectively. Ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was used for the screening of the potential biomarkers in the rat serum and their related metabolic pathways. The results showed that LRWE reduced the AWR score, decreased FWC, and alleviated visceral sensitivity and diarrhea symptoms in IBS-D rats. HE and PAS staining showed that LRWE mitigated low-grade intestinal inflammation and increased the number of mature secretory goblet cells in the colonic epithelium of IBS-D rats. A total of 25 potential biomarkers of LRWE in treating IBS-D were screened out in this study, which were mainly involved in riboflavin, tryptophan, glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, and cysteine and methionine metabolism. The regulatory effects were the most significant on the riboflavin and tryptophan metabolism pathways. LRWE may alleviate the visceral hypersensitivity by promoting energy metabolism and amino acid metabolism, enhancing intestinal barrier function, and improving intestinal immune function in IBS-D rats.

Acceptability of male circumcision for HIV prevention among men who have sex with men in China: a short report.

Recent evidence shows that circumcision is associated with lower HIV prevalence among MSM. We assessed the acceptability of circumcision for preventing HIV and that of Shang Ring circumcision (SRC) among men who have sex with men (MSM) in China. 538 adult MSM were recruited from six cities in China between January and March 2019. Participants were surveyed by an online, self-administered questionnaire. The acceptability of circumcision was assessed before and after the potential protective effect of circumcision against HIV was informed, and subsequently men's willingness to undergo SRC was assessed. The level of circumcision was 16.4%. Of 450 uncircumcised MSM, their willingness to be circumcised in the following six months increased significantly from 32.2% to 55.6% after the information session. Three quarters of men who were willing to undergo circumcision accepted SRC. MSM who perceived that circumcision could maintain genital hygiene were more likely to accept circumcision after the information session, whereas those who regarded circumcision as an embarrassing surgery were disinclined to be circumcised. The low circumcision rate, along with its high acceptability in Chinese MSM, suggests a great potential benefit of circumcision intervention if proved effective. SRC might be a popular circumcision procedure in this population.

Rectal Douching and Anal Human Papillomavirus Among Young Men Who Have Sex With Men in China.

BACKGROUND: Young men who have sex with men (YMSM) are particularly at increased risk for human papillomavirus (HPV) infection and related malignancies. Rectal douching, commonly practiced among MSM, has been associated with HIV, chlamydia, gonorrhea, and viral hepatitis in cross-sectional studies. We conducted this study to understand the association between self-reported rectal douching and anal HPV among YMSM in China. METHODS: Between September 2018 and March 2019, MSM aged 15 to 24 years who ever engaged in receptive anal intercourse over the last 3 months were recruited via community-based organizations and centers for disease control located in 4 cities in China. Participants were asked to complete an online survey. We performed multivariate logistic regression adjusted for potential confounders to examine the association between self-reported rectal douching and anal HPV. RESULTS: Among 273 MSM with a median age of 20 years (interquartile range, 19-21 years) included in this study, 130 (47.6%) practiced rectal douching during the preceding 3 months and 96 (36.2%) were infected with anal HPV. Self-reported rectal douching was found to be associated with increased odds of anal HPV infection (odds ratio, 2.16; 95% confidence interval, 1.22-3.82) among YMSM, after adjusting for age, sexual debut, sex with alcohol or drugs, and HIV testing history. CONCLUSIONS: Self-reported rectal douching is associated with higher odds of anal HPV infection independent of sexual behaviors among YMSM. More prospective studies to ascertain this association are needed. Health education materials should inform men of the potential risk of rectal douching. Research on safer rectal douching procedures is warranted.

Trends of Human Immunodeficiency Virus, Syphilis, and Hepatitis C Infections Among Men Who Have Sex With Men in Chongqing, China: A Serial Cross-sectional Survey From 2011 to 2018.

BACKGROUND: Human immunodeficiency virus (HIV) prevalence and incidence rates have expeditiously increased among Chongqing men who have sex with men (MSM) over the past decade. This study investigated the trends of HIV, syphilis, and hepatitis C virus (HCV) infections and behavioral attributes of Chongqing MSM. METHODS: Chongqing MSM who were 18 years or older were recruited annually from 2011 to 2018. Interviewer-administered paper-pencil interviews were used to collect demographics, behavioral information, and sexually transmitted diseases history. Blood samples were collected for the tests of HIV, syphilis, and HCV. A stepwise regression model was conducted to assess the associations of demographics, behaviors, and syphilis and HCV infections with HIV infection. RESULTS: A total of 4900 MSM participated in the study. The average HIV, syphilis, and HCV prevalence over 8 years were 15.4%, 4.0%, and 0.3%, respectively. The HIV prevalence ranged from 13.5% to 16.4%. Syphilis and HCV were generally low and stable across years. An increased proportion of participants received HIV counseling, testing, and condoms. Multivariable regression indicated that HIV-positive MSM were more likely to be older, married, and less educated, and they were more likely to perform unprotected anal intercourse with male partners in the past 6 months, have syphilis, and less likely to receive HIV counseling, testing, condoms, and peer education in the past year. CONCLUSIONS: The HIV counseling, testing, and peer education programs showed a negative association with HIV-positive status among Chongqing MSM. The HIV prevalence is still high. More programs must be implemented to effectively curb the HIV epidemic.

Trends of HIV, hepatitis C virus and syphilis seroprevalence among injection and non-injection drug users in southwestern China, 2010-2017.

BACKGROUND: The primary risk of HIV transmission in China has shifted from injecting drug use (IDU) to sexual contact since 2006. We evaluated the prevalence trends of HIV, hepatitis C virus (HCV), syphilis, and sexual and drug use behaviors among drug users. Methods: People who use drugs participated in any of four rounds of cross-sectional surveys during 2010-2017 in Chongqing. Participants were tested for HIV, HCV, and syphilis. Questionnaire interviewing was conducted to collect behavioral information. Chi-square and trend tests were employed to assess the changes in diseases and behaviors over time. Results: A total of 8,171 people who inject drugs (PWID) and 5,495 non-injection drug users (NIDU) were included in the analyses. HIV prevalence among PWID in four rounds of the survey in 2010-11, 2012-13, 2014-15, and 2016-17 was 11.5%, 9.7%, 6.5%, and 6.9%, and among NIDU, 2.4%, 1.4%, 2.1% and 2.6%, respectively. HCV prevalence among PWID was 83.5%, 85.2%, 67.1% and 79.7% (P < 0.001), and among NIDU, 22.2%, 10.8%, 13.4% and 14.8%, (P < 0.001). Conclusions: The declining HIV and HCV prevalence among PWID is coincident with declining risky drug use behaviors. Tailored disease prevention and interventions targeting PWID and NIDU are needed.

Effect of availability of HIV self-testing on HIV testing frequency among men who have sex with men attending university in China (UniTest): protocol of a stepped-wedge randomized controlled trial.

BACKGROUND: HIV testing plays a central role in the combat against HIV. We aimed to determine if the availability of HIV self-testing (HIVST) would increase the frequency of testing among men who have sex with men (MSM) attending university in China. METHODS: A stepped wedge randomized controlled trial will be conducted in 4 provinces in China: Chongqing, Guangdong, Shandong, and Tianjin. Eligibility assessment will include (1) male, aged 16 years or older, (2) university student (technical diploma and undergraduate students), (3) MSM (sexual behaviors including mutual masturbation, oral sex, and anal sex), (4) HIV negative, and (5) willing to provide informed consent. Participants will be randomly allocated to HIV self-testing intervention with free HIVST kits in every 30 days according to the intervention waiting lists with a computer-generated randomized sequence. All participants will complete a self-administrated online questionnaire onsite at baseline and 12-month follow-up and complete an online questionnaire at 4- and 8-month. The primary outcome is the effect of HIVST on HIV testing frequency. Secondary outcomes include the change in sexual behaviors and HIV incidence. DISCUSSION: No previous study had measured the effect of social media based HIVST intervention on the change in HIV testing behaviors, sexual behaviors and incident HIV infection among MSM attending university in China. Findings from this study will provide evidence for further interventional practice promotions and prevention strategies scale-up, including HIV testing, pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP), and sexual partner serosorting. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR1900020645. Registered 11 January 2019.

Association between rectal douching and HIV and other sexually transmitted infections among men who have sex with men: a systematic review and meta-analysis.

BACKGROUND: Men who have sex with men (MSM) are disproportionately affected by HIV and other STIs worldwide. Rectal douching, which is commonly used by MSM in preparation for anal sex, may increase the risk of HIV and other STIs by injuring the rectal mucosa. Results from individual studies reporting associations between rectal douching and HIV and other STIs among MSM are inconsistent. We performed a systematic review and meta-analysis to estimate the association between rectal douching and HIV and other STIs among MSM. METHODS: We searched PubMed, Embase, Scopus and Web of Science for studies published from January 1970 to November 2018. Studies that reported ORs and 95% CIs of associations between rectal douching and infection with HIV/STIs, or reported enough data to calculate these estimates, were included. We assessed risk of bias using the Newcastle-Ottawa Scale. ORs were pooled using a random effects model. RESULTS: Twenty-eight eligible studies were identified in our review, of which 24 (20 398 participants) were included in the meta-analysis. Rectal douching was associated with increased odds of infection with HIV (OR 2.80, 95% CI 2.32 to 3.39), and any STI other than HIV (including hepatitis B virus (HBV), hepatitis C virus (HCV), chlamydia, gonorrhoea, syphilis and human papillomavirus) (OR 2.46, 95% CI 1.95 to 3.11) among MSM. For specific STIs, douching was associated with increased odds of viral hepatitis (HBV, HCV) (OR 3.29, 95% CI 2.79 to 3.87), and chlamydia or gonorrhoea (OR 3.25, 95% CI 2.02 to 5.23). These associations remained significant in studies that adjusted for potential confounders. CONCLUSION: Rectal douching may put MSM at increased risk for infection with HIV and other STIs. Longitudinal studies are needed to clarify this association, and health education materials should inform men of the potential for increased risk of infection with rectal douching.

Comprehensive metabolomic, proteomic and physiological analyses of grain yield reduction in rice under abrupt drought-flood alternation stress.

Abrupt drought-flood alternation (T1) is a meteorological disaster that frequently occurs during summer in southern China and the Yangtze river basin, often causing a significant loss of rice production. In this study, the response mechanism of yield decline under abrupt drought-flood alternation stress at the panicle differentiation stage was analyzed by looking at the metabolome, proteome as well as yield and physiological and biochemical indexes. The results showed that drought and flood stress caused a decrease in the yield of rice at the panicle differentiation stage, and abrupt drought-flood alternation stress created a synergistic effect for the reduction of yield. The main reason for the decrease of yield per plant under abrupt drought-flood alternation was the decrease of seed setting rate. Compared with CK0 (no drought and no flood), the net photosynthetic rate and soluble sugar content of T1 decreased significantly and its hydrogen peroxidase, superoxide dismutase, peroxidase activity increased significantly. The identified differential metabolites and differentially expressed proteins indicated that photosynthesis metabolism, energy metabolism pathway and reactive oxygen species response have changed strongly under abrupt drought-flood alteration stress, which are factors that leads to the rice grain yield reduction.

STAT3-mediated epigenetic silencing of FOXP3 in LADA T cells is regulated through HDAC5 and DNMT1.

In LADA patients, Tregs are reduced and FOXP3 is downregulated in CD4+ T cells, but the etiology remains unclear. Our study included in 20 LADA patients and 20 healthy control patients. qRT-PCR results showed that STAT3, HDAC3, HDAC5, SIRT1, DNMT1 and DNMT3b mRNAs were significantly upregulated in LADA CD4+ T cells than controls, while FOXP3 mRNA significantly decreased. p-STAT3, STAT3, DNMT1 and DNMT3b expressions were increased demonstrated by western blot. ChIP-PCR suggested that p-STAT3 binds to the Foxp3 promoter, meanwhile, histone H3 acetylation at K9 and K14 of FOXP3 promoter were significantly lower than controls. Luciferase reporter assay showed that ectopic STAT3 expression significantly reduced FOXP3 promoter activities. The Foxp3 promoter was significantly hypermethylated in LADA than controls. LADA patients showed stronger binding of p-STAT3, HDAC5 and DNMT1 than controls using CHIP. These findings reveal a crucial role of STAT3 in regulating the epigenetic status of T cells in LADA.

[Molecular mechanism of Mylabris for colorectal cancer based on integrative pharmacology].

At present, the disjointing situation is generally present between "systemic"and "local", "macro" and "micro", "in vivo process" and "activity evaluation" in the study of traditional Chinese medicine (TCM). An urgent task for the modernization of TCM is to establish new strategies and methods which can reflect the overall characteristics of TCM. The introduction of integrative pharmacology provided a feasible approach to solve the problem of the fragmentation of TCM. Internet-based computation platform method was adopted in this study to explore the active molecular mechanism of Mylabris in the treatment of colorectal cancer. Based on the analysis of the functional integration of internet-based computation platform V1.0 version software, the "core components-key target- main pathway" multidimensional network of Mylabris in treatment of colorectal cancer disease was constructed to explore the potential molecular mechanism of Mylabris in treatment of colorectal cancer from multiple perspectives. The results showed that Mylabris can treat the colorectal cancer and the mechanism might be associated with amino acid metabolism, NF-κB signaling pathway, immune system, endocrine system, nervous system, and chemokine signal transduction pathway, epithelial cell signaling in helicobacter pylori infection, T cell receptor signaling pathway, B cell receptor signaling pathway and so on.

[Relationship between histone acetylation modification in spleen CD4+T cells and diabetic nephropathy of nonobese diabetic mice].

OBJECTIVE: To explore the relationship between histone acetylation modification in spleen CD4+T cells and diabetic nephropathy. METHODS: Non-obese diabetic (NOD) mice were randomly divided into 4 groups and random blood glucose at 12, 18, 24 and 30 weeks were detected. Urinary albumin and creatinine were detected by enzyme-linked immunosorbent assay (ELISA). The global acetylation levels of H3 and H4 in CD4+T cells were measured by H3/H4 acetylation kit. The relevant mRNA expression level of histone acetylation modification enzymes was detected by real-time quantitative polymerase chain reaction (PCR) and the altered expression genes verified by Western blot. RESULTS: Compared with mice from 12 weeks, there were significant increases in blood glucose levels and urinary albumin/creatinine ratio (ACR) from 24 and 30 weeks (glucose: (18.1±6.3) and (20.7±7.5) vs (7.2±3.1) mmol/L, ACR: (4.04±1.54) and (8.11±1.77) vs (2.12±0.56) mg/g). Conversely, the global acetylation levels of H3 (0.068±0.023 and 0.043±0.017 vs 0.127±0.036) and H4 (0.058±0.022 and 0.041±0.019 vs 0.082±0.032) in spleen CD4+T cells from 24 and 30 weeks were obviously lower. The mRNA levels of such histone acetylases as P300 (15.53±6.31 and 13.76±3.62 vs 22.94±7.40) and P300/CBP-associated factor (PCAF) (3.21±0.81 and 2.74±0.36 vs 5.31±0.73) declined while the protein and mRNA of histone deacetylase 5 (HDAC5) significantly increased from 24 and 30 weeks. All the above differences were statistically significant (P<0.05). The levels of H3 (r=-0.590, P=0.043) and H4 (r=-0.702, P=0.011) were negatively correlated with urinary ACR while HDAC5 level was positively correlated with urinary ACR from 24 and 30 weeks (r=0.673, P=0.016). CONCLUSIONS: With aging and progression of nephropathy in NOD mice, the global acetylation levels of H3 and H4 decrease while the expression level of HDAC5 increases in spleen CD4+T cell. And altered HDAC5 expression in spleen CD4+T cells is closely correlated with kidney damage in NOD mice.

[The survival and development conditions of community-based organizations for HIV/AIDS prevention and control among men who have sex with men in three Chinese cities].

OBJECTIVE: To investigate the survival and development conditions of community-based organizations (CBOs) for HIV/AIDS prevention and control among men who have sex with men (MSM) in Chinese cities including Shanghai, Hangzhou, Chongqing. METHODS: This study employed both qualitative (focus groups) and quantitative (questionnaire survey) methods to obtain information from 15 MSM CBOs in three Chinese cities. RESULTS: The mean work time of the 15 CBOs for HIV/AIDS prevention and control among MSM was 6.7 years (2.1-11.3 years), and the majority of their funds was from international cooperation projects (80 447 000 RMB, 73.0%) from 2006 to 2013. The survival cost of MSM CBOs apart from expenditure of activities was 2 240-435 360 RMB per year. As it was shown in the graph, the survival and development of MSM CBOs was closely related to the development of international cooperation projects. There was a few small size MSM CBOs taking part in the prevention and control of HIV/AIDS and their work content was limited before 2006. From 2006 to 2008, some international cooperation projects were launched in China, such as the China Global Fund AIDS project and the China-Gates Foundation HIV Prevention Cooperation program. As a result, the number of MSM CBOs was increased sharply, and both the scale and 2012, the performance of these programs further promote the establishment of new MSM CBOs and the development of all MSM CBOs with regard to the work places, full-time staffs, work contents, work patterns and the specific targeted population. After 2012, most international cooperation programs were completed and the local department of disease prevention and control continued to cooperate with MSM CBOs. However, the degree of support funds from the local department was different among different regions. Where the funds were below the half of program funds, the development of MSM CBOs ceased and work slowed down. Besides, there were still some constraints for the survival and development of MSM CBOs, such as insufficient funds, no legitimate identity, the outflow of talents and the unsustainable development. CONCLUSION: The survival and development of MSM CBOs was closely related to the development of international cooperation projects in China. Some departments of disease prevention and control took over the cooperation with MSM CBOs when the international cooperation projects were completed. Given the survival cost of MSM CBOs and the constraints of MSM CBOs development, it needs further investigation on how to ensure the local departments of disease prevention and control to take over the cooperation with MSM CBOs and how to cooperate with MSM CBOs.

[Intervention and therapeutic effect of siRNA-HDAC5 on abnormal histone modification in non-obese diabetic mice].

OBJECTIVE: To evaluate therapeutic eff ect of siRNA-HDAC5 on non-obese diabetic (NOD) mice by using small interference RNA (siRNA) technique to knock down the expression of HDAC5 in spleen CD4+ T cells. METHODS: NOD mice, 12-weeks old, were randomly divided into 3 groups and were given normal saline, siRNA-Control or siRNA-HDAC5 through caudal vein injection. The spleens and other samples were collected at the 18th, 24th or 30th week. The blood glucose was tested by blood glucose meter. The urinary albumin and serum levels of IL-1, IL-6, IL-18, and TNF-α were detected by ELISA. The mRNA levels of CD11a, CCR5, and CX3CR1 in spleen CD4+ T cells were measured by quantitative Real-time PCR. The HDAC5 protein level in spleen CD4+ T cell was detected by Western blot. RESULTS: Compared with the control group, the siRNA-HDAC5 group showed a significant decrease in blood glucose, urine albumin excretion rate, serum cytokine and the mRNA levels of CD11a, CCR5, and CX3CR1, consist with the decrease in protein level of HDAC5. CONCLUSION: Inhibition of HDAC5 expression in NOD mice could effectively alleviate the onset and development of kidney damage caused by diabetes.

Mean Blood Glucose Level During ICU Hospitalization is a Strong Predictor of the Mortality of COVID-19.

Objective: To investigate the potential prognostic value of mean blood glucose (MBG) in hospital for prognosis of COVID-19 adult patients in the intensive unit care unit (ICU). Methods: A single-site and retrospective study enrolled 107 patients diagnosed as COVID-19 from department of critical care medicine in the Second Xiangya Hospital between October 2022 and June 2023. Demographic information including glucose during ICU hospitalization, comorbidity, clinical data, types of medications and treatment, and clinical outcome were collected. The multivariate logistic and cox regression was used to explore the relationship between blood glucose changes and clinical outcomes of COVID-19 during ICU stay. Results: In total, 107 adult patients confirmed with COVID-19 were included. Multivariate logistic regression results showed an increase in MBG was associated with ICU mortality rate. Compared with normal glucose group (MBG <= 7.8 mmol/L), the risk of ICU mortality, 7-day mortality and 28-day mortality from COVID-19 were significantly increased in high glucose group (MBG >7.8mmol/L). Conclusion: MBG level during ICU hospitalization was strongly correlated to all-cause mortality and co-infection in COVID-19 patients. These findings further emphasize the importance of overall glucose management in severe cases of COVID-19.

Evaluating lumbar disc degeneration by MRI quantitative metabolic indicators: the perspective of factor analysis.

PURPOSE: This study aimed to investigate an early diagnostic method for lumbar disc degeneration (LDD) and improve its diagnostic accuracy. METHODS: Quantitative biomarkers of the lumbar body (LB) and lumbar discs (LDs) were obtained using nuclear magnetic resonance (NMR) detection technology. The diagnostic weights of each biological metabolism indicator were screened using the factor analysis method. RESULTS: Through factor analysis, common factors such as the LB fat fraction, fat content, and T2* value of LDs were identified as covariates for the diagnostic model for the evaluation of LDD. This model can optimize the accuracy and reliability of LDD diagnosis. CONCLUSION: The application of biomarker quantification methods based on NMR detection technology combined with factor analysis provides an effective means for the early diagnosis of LDD, thereby improving diagnostic accuracy and reliability.

Correlates of sexual and reproductive health service utilization among older adults in China: Findings from the sexual well-being (SWELL) study.

BACKGROUND: Sexual and reproductive health (SRH) is critical to the overall health of older adults. We assessed the utilization of SRH services and its correlates among older adults in China. METHODS: We recruited community-dwelling adults aged 50 and above in five Chinese cities between June 2020 and December 2022. In this study SRH services included reproductive health examination, cervical cancer screening, and sexual life counselling. Logistic regression was used to assess correlates of SRH services utilization. RESULTS: A total of 3001 older adults (1819 men and 1182 women) were enrolled. Among them, 11.4 % (343/3001) of participants received a reproductive health examination, 35.4 % (418/1182) of female participants received cervical cancer screening, and 30.1 % (401/1332) of sexually active participants sought help for their sexual lives. Older men with an annual income of USD 7500 or more (aOR = 3.21, 95%CI: 1.39-7.44), two or more chronic conditions (2.38, 1.39-4.08), and reproductive health problems (2.01, 1.18-3.43) were more likely to receive a urological examination. For older women, individuals who were younger (aged 50-59 years: 5.18, 2.84-9.43; aged 60-69 years: 2.67, 1.49-4.79), lived in an urban area (1.88, 1.31-2.71), were employed (1.73, 1.21-2.47), had two or more chronic conditions (2.04, 1.37-3.05), were sexually active (1.72, 1.15-2.58) and talked about sex (1.69, 1.21-2.36) were more likely to receive a gynecological examination. CONCLUSION: SRH services utilization among older adults was low, with urological examination among older men particularly low. SRH messages and services tailored for older adults are needed to enhance their utilization of SRH services.

Sexual function and correlates among adults aged 50+ years in China: Findings from the sexual well-being (SWELL) study.

BACKGROUND: Sexual function is an important yet understudied aspect of overall health and well-being in older adults. We aimed to examine sexual function and its correlates among people 50 years and older in China. METHODS: We enrolled people aged 50 years and older recruited from four regions in China between September 2021 and July 2022 in a multicenter cross-sectional study. Data were collected through an investigator-administered questionnaire about demographic characteristics, health characteristics, and sexual function status. Logistic regression was used to assess correlates of lower sexual function (the highest quintile of the sex-specific population distribution of Natsal-SF scores [i.e., lower functioning compared with the remaining]). RESULTS: A total of 465 women and 832 men who were sexually active in the past year were included in the analysis (mean age: 60.4 ± 7.2) [Correction added after first online publication on 12 Feb 2024. The word "years" has been changed to "year" in this sentence.]. Over a quarter of all participants were dissatisfied with their sex life. Notably, 92 women and 167 men were categorized as having a lower sexual function. Age (in men only), living in urban areas, general health status, being underweight or overweight (in men only), and having depressive symptoms were associated with lower sexual function. Among all participants, 43.1% of men and 54.0% of women experienced sexual response problems lasting 3 months or more. Less than one-third of all participants had sought help or advice for sex life in the past year. CONCLUSIONS: Sexual dysfunction and sexual dissatisfaction are prevalent among older adults in China and are associated with self-assessed poor health.

Quantitative analysis of the association between interleukin-10 1082A/G polymorphism and susceptibility to sepsis.

There are some epidemiological studies investigating the association between interleukin-10 (IL-10) 1082A/G polymorphism and sepsis susceptibility reporting conflicting findings. Our work tried to further quantitatively assess the association of the IL-10 1082A/G polymorphism with sepsis susceptibility through a systematic review and meta-analysis. A total of eleven studies with 2,528 subjects were finally included into the meta-analysis. Pooled odds ratios (ORs) and corresponding 95 % confidence intervals (95 % CIs) were calculated with random-effects model or fixed-effects model based on the heterogeneity among the included studies. Meta-analysis of all 11 studies showed that there was an obvious association between IL-10 1082A/G polymorphism and sepsis susceptibility under the allele comparison model (G vs A) and the codominant model (GG vs AA) (for G vs A: OR = 0.83, 95 % CI 0.72-0.96, P = 0.011; for GG vs AA: OR = 0.67, 95 % CI 0.47-0.96, P = 0.029). Subgroup analysis by ethnicity showed that there was an obvious association between IL-10-1082A/G polymorphism and sepsis susceptibility in Asians under three comparison models (for G vs A: OR = 0.75, 95 % CI 0.62-0.91, P = 0.004; for GG vs AA: OR = 0.39, 95 % CI 0.21-0.73, P = 0.003; for GG vs AA/AG: OR = 0.36, 95 % CI 0.14-0.92, P = 0.032), but there was no similar association in Caucasians under all four comparison models. Our meta-analysis reveals that the IL-10-1082A/G polymorphism has an association with the susceptibility to sepsis in Asian populations. Further studies are needed to investigate the effect of IL-10-1082A/G polymorphism on sepsis susceptibility in Caucasians.
