Purpose: Although transgender women (TGW) bear the highest HIV burden worldwide, routine surveillance of this group is rare. We aimed to evaluate the trends in health characteristics of Chinese TGW. Methods: Three cross-sectional studies using snowball sampling were conducted in 2014, 2017, and 2019, primarily in Shenyang, China. A questionnaire and voluntary HIV testing were used to obtain information on background characteristics, sexual behaviors, pre-exposure prophylaxis (PrEP) willingness, and HIV status. Results: There were 220 respondents in 2014, 198 in 2017, and 247 in 2019 (average age 31.1±7.6 to 33.5±9.6 years). HIV prevalence significantly decreased from 29.5% (95% confidence interval [CI]: 25.3–38.4%) in 2014 to 19.4% (95% CI: 14.7–24.9%) in 2019 (p<0.05). The proportion of participants reporting condomless anal intercourse (CAI) with any partner fluctuated from 30.8% (95% CI: 25.1–36.1%) to 53.0% (95% CI: 45.8–60.1%). The proportion of participants willing to use PrEP decreased from 86.4% (95% CI: 81.1–90.6%) in 2014 to 62.8% (95% CI: 56.4–68.8%) in 2019. Factors significantly associated with HIV infection were CAI with any partner (multivariate odds ratio [ORm]: 3.58, 95% CI: 1.55–8.29 in 2017; ORm: 3.18, 95% CI: 1.56–6.46 in 2019) and PrEP willingness (ORm: 0.26, 95% CI: 0.12–0.58 in 2017). Conclusion: HIV prevalence and associated risk factors remain substantial among Chinese TGW. There is an urgent need to strengthen HIV surveillance in this population, and develop trans-friendly and effective interventions to minimize HIV prevalence and transmission. [ABSTRACT FROM AUTHOR]

Purpose: High prevalence of depression in transgender women highlights the importance of validating the measure to assess depression. Moreover, depression is significantly associated with suicide across research studies. The aims of the current study were to validate a Chinese-language version of the Patient Health Questionnaire-9 (PHQ-9) and to assess operating characteristics of the PHQ-9 for suicide screening in transgender women. Methods: With the approval of an Institutional Review Board (IRB), a total of 198 transgender women living in Shenyang, China, were recruited, and asked to complete the PHQ-9, including measures of their suicidal ideation, planning and attempt. Results: A one-factor model of the PHQ-9 was supported in the current sample, showing good reliability and validity. The best cutoff point for the PHQ-9 in suicidal ideation was 17, with a sensitivity/specificity of 77.78%; the best cutoff point for PHQ-9 in suicidal planning was 17, with a sensitivity of 81.82% and a specificity of 73.26%; and the best cutoff point for PHQ-9 in suicidal attempt was 20, with a sensitivity of 75% and a specificity of 90.21%. Conclusion: Findings supported the validity of the PHQ-9. With potential clinical or research application, the PHQ-9 can be an efficient instrument for suicide screening in transgender women.

The aim of this network meta-analysis is to compare bone mineral density (BMD) changes among different osteoporosis prevention interventions in postmenopausal women. We searched MEDLINE, Embase and Cochrane Library from inception to 24 February 2019. Included studies were randomised controlled trials (RCT) comparing the effects of different treatments on BMD in postmenopausal women. Studies were independently screened by six authors in three pairs. Data were extracted independently by two authors and synthesised using Bayesian random-effects network meta-analysis. The results were summarised as mean difference in BMD and surface under the cumulative ranking (SUCRA) of different interventions. A total of ninety RCT (10 777 participants) were included. Ca, vitamin D, vitamin K, oestrogen, exercise, Ca + vitamin D, vitamin D + vitamin K and vitamin D + oestrogen were associated with significantly beneficial effects relative to no treatment or placebo for lumbar spine (LS). For femoral neck (FN), Ca, exercise and vitamin D + oestrogen were associated with significantly beneficial intervention effects relative to no treatment. Ranking probabilities indicated that oestrogen + vitamin D is the best strategy in LS, with a SUCRA of 97·29 % (mean difference: +0·072 g/cm2 compared with no treatment, 95 % credible interval (CrI) 0·045, 0·100 g/cm2), and Ca + exercise is the best strategy in FN, with a SUCRA of 79·71 % (mean difference: +0·029 g/cm2 compared with placebo, 95 % CrI –0·00093, 0·060 g/cm2). In conclusion, in postmenopausal women, many interventions are valuable for improving BMD in LS and FN. Different intervention combinations can affect BMD at different sites diversely.

Background: The effect of nirmatrelvir-ritonavir on post-COVID-19 outcomes for individuals who are immunocompromised is understudied. We aimed to examine the association of nirmatrelvir-ritonavir with post-acute sequelae and mortality among patients who are immunocompromised and admitted to hospital with COVID-19., Methods: We did a retrospective cohort study using territory-wide electronic health records from the Hong Kong Hospital Authority and Hong Kong Department of Health. Eligible patients were adults aged 18 years or older who tested positive for SARS-CoV-2 during the study period (March 11, 2022, to Nov 9, 2023) and were admitted to hospital with COVID-19. Four exposure groups were formed based on immune status (immunocompromised or immunocompetent) and nirmatrelvir-ritonavir status (yes or no). The primary outcome was post-acute inpatient death, starting from 21 days after the positive RT-PCR date. Standardised mortality ratio weighting with doubly robust adjustment was applied to control for confounders. Cox models were used to estimate hazard ratios (HRs) for the outcomes., Findings: Between March 11, 2022, and Nov 9, 2023, there were 89 772 individuals with positive RT-PCR tests, of whom 39 923 met eligibility criteria and were included in the study cohort. 19 914 (49·9%) of 39 923 patients were female, 20 009 (50·1%) were male and the median age was 75·0 years (IQR 63·0-85·0). 846 (38·2%) of 2217 patients who were immunocompromised and 14 586 (38·7%) of 37 706 patients who were immunocompetent were prescribed nirmatrelvir-ritonavir. Among the patients who were immunocompromised, those patients who received nirmatrelvir-ritonavir had significantly lower risk of post-acute inpatient death (HR 0·58, 95% CI 0·45-0·74; p<0·0001) and hospitalisation for acute respiratory distress syndrome (0·43, 0·20-0·90; p=0·024) than those who did not. A significant negative interaction was found between immune status and nirmatrelvir-ritonavir on post-acute all-cause hospitalisation (relative excess risk due to interaction -0·84, 95% CI -1·30 to -0·37; p=0·0004)., Interpretation: Nirmatrelvir-ritonavir was associated with reduced risk of post-acute inpatient death among patients who were immunocompromised and admitted to hospital with COVID-19. However, the effectiveness of nirmatrelvir-ritonavir on post-acute hospitalisation outcomes was less pronounced in patients who were immunocompromised than in patients who were immunocompetent., Funding: Health and Medical Research Fund, Research Grants Council theme-based research schemes, and Research Grants Council Collaborative Research Fund., Competing Interests: Declarations of interests We declare no competing interests., (Copyright © 2024 Elsevier Ltd.

While previous research examined coronavirus disease 2019 (COVID-19) antiviral-vaccine interactions through exploratory subgroup analysis, none specifically designed for examining this interaction or its impact on post-acute outcomes. This study examined the interaction between nirmatrelvir-ritonavir and complete COVID-19 vaccination on reducing the risk of post-acute outcomes among COVID-19 patients. We followed COVID-19 patients hospitalized between 11 March 2022 and 10 October 2023, until 31 October 2023 in Hong Kong. Exposure groups were based on nirmatrelvir-ritonavir usage and vaccination status (fully or not fully vaccinated). Post-acute death and all-cause rehospitalization were the study outcomes. Propensity score weighting was applied to balance covariates among exposure groups, including age, sex, Charlson Comorbidity Index, and concomitant treatments. Multiplicative and additive interactions between nirmatrelvir-ritonavir and vaccination status were assessed. A total of 50,438 COVID-19 patients were included in this study and arranged into four exposure groups. Significant additive interaction on post-acute rehospitalization was observed (relative excess risk, 0.10; 95% CI, 0.02-0.19; p -value, 0.018; attributable proportion, 0.07; 95% CI, 0.01-0.12; p -value, 0.017; synergy index, 1.26; 95% CI, 1.02-1.55; p -value, 0.032). The interaction on post-acute mortality was marginally significant. In the subgroup analysis, the interaction effect is more pronounced in older adults, female, and CoronaVac recipients. In conclusion, our study demonstrated an additive interaction between nirmatrelvir-ritonavir and complete vaccination on post-acute outcomes, suggesting greater long-term benefits of the antiviral for fully vaccinated individuals compared to not fully vaccinated patients.

Background: While coronavirus 2019 (COVID-19) deaths were generally underestimated in many countries, Hong Kong may show a different trend of excess mortality due to stringent measures, especially for deaths related to respiratory diseases. Nevertheless, the Omicron outbreak in Hong Kong evolved into a territory-wide transmission, similar to other settings such as Singapore, South Korea, and recently, mainland China. We hypothesized that the excess mortality would differ substantially before and after the Omicron outbreak., Methods: We conducted a time-series analysis of daily deaths stratified by age, reported causes, and epidemic wave. We determined the excess mortality from the difference between observed and expected mortality from 23 January 2020 to 1 June 2022 by fitting mortality data from 2013 to 2019., Results: During the early phase of the pandemic, the estimated excess mortality was -19.92 (95% confidence interval (CI) = -29.09, -10.75) and -115.57 (95% CI = -161.34, -69.79) per 100 000 population overall and for the elderly, respectively. However, the overall excess mortality rate was 234.08 (95% CI = 224.66, 243.50) per 100 000 population overall and as high as 928.09 (95% CI = 885.14, 971.04) per 100 000 population for the elderly during the Omicron epidemic. We generally observed negative excess mortality rates of non-COVID-19 respiratory diseases before and after the Omicron outbreak. In contrast, increases in excess mortality were generally reported in non-respiratory diseases after the Omicron outbreak., Conclusions: Our results highlighted the averted mortality before 2022 among the elderly and patients with non-COVID-19 respiratory diseases, due to indirect benefits from stringent non-pharmaceutical interventions. The high excess mortality during the Omicron epidemic demonstrated a significant impact from the surge of COVID-19 infections in a SARS-CoV-2 infection-naive population, particularly evident in the elderly group., Competing Interests: Disclosure of interest: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interests., (Copyright © 2023 by the Journal of Global Health.
