ObjectiveThree models for promoting male circumcision (MC) as a preventative intervention against HIV infection were compared among migrant worker populations in western China.MethodsA cohort study was performed after an initial cross-sectional survey among migrant workers in three provincial level districts with high HIV prevalence in western China. A total of 1,670 HIV seronegative male migrants were cluster-randomized into three intervention models, in which the dissemination of promotional materials and expert- and volunteer-led discussions are conducted in one, two, and three stage interventions. Changes in knowledge of MC, acceptability of MC, MC surgery uptake, and the costs of implementation were analyzed at 6-month and 9-month follow-up visits.ResultsAll three models significantly increased the participants’ knowledge about MC. The three-stage model significantly increased the acceptability of MC among participants and led to greatest increase in MC uptake. At the end of follow-up, 9.2% (153/1,670) of participants underwent MC surgery; uptake among the one-, two-, and three-stage models were 4.9%, 9.3%, and 14.6%, respectively. Multivariable Cox regression analysis showed that three-stage model was the most effective method to scale up MC, with RR = 2.0 (95% CI, 1.3-3.1, P=0.002) compared to the on-site session model. The two-stage intervention model showed no significant difference with either the on-site session model (RR=1.5, 95% CI, 0.92-2.4, P=0.12) or three-stage model (P=0.10).ConclusionsA three-stage intervention with gradual introduction of knowledge led to the significantly increase in MC uptake among migrant workers in western China, and was also the most cost-effective method among the three models.
We aimed to explore the association between albuminuria and clinical outcomes in patients with diabetic foot osteomyelitis (DFO).Methods: This is an observational retrospective study and a total of 202 inpatients with DFO were eligible for inclusion in our study. Based on urine albumin-creatinine ratio (UACR), the patients were divided into three groups: normoalbuminuria group, microalbuminuria group and macroalbuminuria group. The data collected include demographics data, laboratory data, clinical diagnostic data, diabetic foot examination and clinical visit data. The association was then evaluated between albuminuria and all-cause mortality, major cardiovascular adverse events (MACE) and mixed endpoint events.Results: The mean age was 60.3 years, 62.9% were male and 45.05% were urinary proteinpositive. The incidence rates of all-cause mortality, MACE and mixed endpoint events related to elevated UACR were significantly increased in patients with DFO (all P for trend < 0.01). After adjusting for confounders, compared with normoalbuminuria group, the risk of all-cause mortality, MACE and mixed endpoint events in the microalbuminuria group increased by 81.8%, 135.4% and 136.4%, respectively. The risk of all-cause mortality, MACE and mixed endpoint events in the macroalbuminuria group increased by 246.2%, 145.1% and 252.3%, respectively. The population attributable risk percentage (PAR%) suggested that 50.16% of all-cause mortality, 47.85% of MACE and 59.11% of mixed endpoint events could be attributed to the elevated UACR. Meanwhile, compared with normoalbuminuria, those with microalbuminuria or macroalbuminuria have lower apoA1 and ABI, higher SCr and higher incidence rate of CHD, hindfoot infection and severe infection (all P < 0.05).
To describe the acceptability of male circumcision (MC) and explore potential factors associated with MC acceptability among male rural-to-urban migrants in western China, a cross-sectional survey of MC acceptability was conducted with 1,904 subjects in three western provinces with high HIV prevalence (Guangxi, Chongqing, and Xinjiang) in China between June 2009 and November 2009. Through face-to-face interviews, the participants completed a self-administered questionnaire about demographics, MC knowledge, willingness and reasons to accept or refuse MC, sexual behaviors, and other psychosocial variables. Factors associated with acceptability of MC were identified by multiple logistic regression analysis. Of the participants (n = 1,904), 710 men were willing to accept MC (37.3%); the reasons included promotion of the partners' genital hygiene (54.9%), redundant prepuce or phimosis (43.1%), enhancement of sexual pleasure (40.6%), prevention of penile inflammation or cancer (35.5%), and protection against HIV and sexual transmitted diseases (STDs)(31.1%). A multivariable logistic regression showed that four factors were associated with acceptability of MC, including education level (OR = 1.286, 95% CI = 1.025*1.614), redundant prepuce or phimosis (OR = 13.751, 95% CI = 10.087*18.745), having one or more circumcised friends (OR = 2.468, 95% CI = 1.953*3.119), and having sexual intercourse with a temporary partner in the past year (OR = 1.543, 95% CI = 1.101*2.162). Compared with previously published data among the general population in China or worldwide, the acceptability of MC (37.3%) was low among the male rural-to-urban migrants in western China. Nevertheless, appropriate education could greatly improve the acceptability of MC. More public campaigns and health education on MC are needed to increase the rate of MC in China.
BackgroundSeveral studies have analyzed the relationship between body mass index (BMI) and the prognosis of breast cancer (BC). However, whether their relationship is linear or curvilinear remains unclear. This cohort study examined the specific relationship between BMI and BC outcomes.MethodsThis retrospective cohort study included 1049 BC patients from March 7, 2013 through December 31, 2019 in a hospital. Kaplan-Meier curves, multivariate Cox proportional models, and restricted cubic spline (RCS) was used to analysis the relationship between BMI and overall survival (OS) and breast cancer-specific survival (BCSS) was analyzed.ResultsDuring a median of 4.87 (IQR:3.26-6.84) years of follow-up period, 71 patients (6.77%) died, of which 50 (70.42%) were attributed to BC. RCS analysis revealed a U- shaped relationship between BMI levels and OS and BCSS after adjusting for other variables. The turning points of the U-shaped curves were 23 kg/m2. On the left side of the turning point, the risk of OS (HR, 0.83; 95% CI, 0.70, 0.98) and BCSS (HR, 0.80; 95% CI, 0.65, 0.98) were adversely correlated with BMI. In contrast, to the right of the turning point, the risk of OS (HR, 1.22; 95% CI, 1.10, 1.37) and BCSS (HR, 1.28; 95% CI, 1.13, 1.46) was positively related to BMI. Kaplan-Meier curves and multivariate Cox regression analyses shown consistent results with RCS analyses.ConclusionBMI was an independent prognostic factor for BC, and had a U-shaped relationship with OS and BCSS. Interventions should be designed to improve patient outcomes based on BMI.
Aim The purpose of this study was to explore the association between estimated glomerular filtration rate (eGFR) and clinical outcomes in patients with diabetic foot osteomyelitis (DFO). Methods This was a retrospective observational study. A total of 199 patients with DFO were recruited and divided into three groups by eGFR: normal kidney function group (eGFR ≥ 90), mildly decreased kidney function group (eGFR 60–89) and moderately to severely decreased kidney function group (eGFR < 60). The patients were followed-up for a median of 36 months, and the study outcomes were all-cause mortality and major cardiovascular adverse events (MACE). Cox proportional hazard models were used to assess the association between eGFR and the outcomes, and a stratified analysis by sex was conducted. Results During follow-up, all-cause mortality occurred in 51 (25.63%) patients among 199 participants, 54 (28.72%) had MACE in 188 participants and 26 (48.15%) of them died. After fully adjusting for potential confounders, compared to eGFR < 90 mL/min/1.73 m 2 , eGFR ≥ 90 mL/min/1.73 m 2 had lower incidence of all-cause mortality (HR = 0.43, 95% CI: 0.22–0.85; P = 0.015) and MACE (HR = 0.51, 95% CI: 0.27–0.96; P = 0.038). Additionally, compared to eGFR < 90 mL/min/1.73 m 2 , eGFR ≥ 90 mL/min/1.73 m 2 was independently associated with decreased risk of all-cause mortality (HR = 0.33; 95% CI 0.14–0.76, P = 0.010) and MACE (HR = 0.27; 95% CI 0.11–0.65, P = 0.004) in male, but not in female. Conclusion In conclusion, decreased eGFR is a risk factor for all-cause mortality and MACE in individuals with DFO. Additionally, male with decreased eGFR had a higher risk of all-cause mortality and MACE, but female did not.
