Introduction: Learning one’s HIV status through HIV testing services (HTS) is an essential step toward accessing treatment and linking to preventive services for those at high HIV risk. HTS may impact subsequent sexual behaviour, but the degree to which this varies by population or is true in the setting of contemporary HIV prevention activities is largely unknown. As part of the 2019 World Health Organization Consolidated Guidelines on HTS, we undertook a systematic review and meta‐analysis to determine the effect of HTS on sexual behaviour.Methods: We searched nine electronic databases for studies published between July 2010 and December 2019. We included studies that reported on at least one outcome (condom use [defined as the frequency of condom use or condom‐protected sex], number of sex partners, HIV incidence, STI incidence/prevalence). We included studies that prospectively assessed outcomes and that fit into one of three categories: (1) those evaluating more versus less‐intensive HTS, (2) those of populations receiving HTS versus not and (3) those evaluating outcomes after versus before HTS. We conducted meta‐analyses using random‐effects models.Results and discussion: Of 29 980 studies screened, 76 studies were included. Thirty‐eight studies were randomized controlled trials, 36 were cohort studies, one was quasi‐experimental and one was a serial cross‐sectional study. There was no significant difference in condom use among individuals receiving more‐intensive HTS compared to less‐intensive HTS (relative risk [RR]=1.03; 95% CI: 0.99 to 1.07). Condom use was significantly higher after receiving HTS compared to before HTS for individuals newly diagnosed with HIV (RR = 1.65; 95% CI: 1.36 to 1.99) and marginally significantly higher for individuals receiving an HIV‐negative diagnosis (RR = 1.63; 95% CI: 1.01 to 2.62). Individuals receiving more‐intensive HTS reported fewer sex partners at follow‐up than those receiving less‐intensive HTS, but the finding was not statistically significant (mean difference = −0.28; 95% CI: −3.66, 3.10).Conclusions: Our findings highlight the importance of using limited resources towards HTS strategies that focus on early HIV diagnosis, treatment and prevention services rather than resources dedicated to supplementing or enhancing HTS with additional counselling or other interventions.

Rationale: United States veterans represent an important population to study sarcoidosis. Their unique history of environmental exposures, wide geographic distribution, and long-term enrollment in a single integrated healthcare system provides an unparalleled opportunity to understand the incidence, prevalence, and risk factors for sarcoidosis. Objectives: To determine the epidemiology, patient characteristics, geographic distribution, and associated risk factors of sarcoidosis among U.S. veterans. Methods: We used data from the Veterans Health Administration (VHA) electronic health record system between 2003 and 2019 to evaluate the annual incidence, prevalence, and geographic distribution of sarcoidosis (defined using the International Classification of Diseases codes). We used multivariate logistic regression to examine patient characteristics associated with sarcoidosis incidence. Results: Among more than 13 million veterans who received care through or paid for by the VHA, 23,747 (0.20%) incident diagnoses of sarcoidosis were identified. Compared with selected VHA control subjects using propensity score matching, veterans with sarcoidosis were more likely to be female (13.5% vs. 9.0%), of Black race (52.2% vs. 17.0%), and ever–tobacco users (74.2% vs. 64.5%). There was an increase in the annual incidence of sarcoidosis between 2004 and 2019 (from 38 to 52 cases/100,000 person-years) and the annual prevalence between 2003 and 2019 (from 79 to 141 cases/100,000 persons). In a multivariate logistic regression model, Black race (odds ratio [OR], 4.49; 95% confidence interval [CI], 4.33–4.65), female sex (OR, 1.64; 95% CI, 1.56–1.73), living in the Northeast compared with the western region (OR, 1.57; 95% CI, 1.48–1.67), history of tobacco use (OR, 1.36; 95% CI, 1.31–1.41), and serving in the Army, Air Force, or multiple branches compared with the Navy (OR, 1.08; 95% CI, 1.03–1.13; OR, 1.10; 95% CI, 1.04–1.17; OR, 1.27; 95% CI, 1.16–1.39, respectively) were significantly associated with incident sarcoidosis (P < 0.0001). Conclusions: The incidence and prevalence of sarcoidosis are higher among veterans than in the general population. Alongside traditionally recognized risk factors such as Black race and female sex, we found that a history of tobacco use within the Veterans Affairs population and serving in the Army, Air Force, or multiple service branches were associated with increased sarcoidosis risk.

Fungal diseases are associated with high morbidity and mortality, yet their epidemiology and burden are not well addressed. While deaths probably exceed 1.5 million per year, many cases remain undiagnosed and underreported. Estimating the burden of these diseases is needed for prioritization and implementation of effective control programs. Here we used a model based on population at risk to estimate the burden of serious fungal infections in Sudan. The prevalence of the susceptible population including HIV, TB, cancer, asthma, and COPD was obtained from the literature. Incidence and prevalence of fungal infections were calculated using local data when applicable and if not available then regional or international figures were used. In total, the estimated number of Sudanese suffering from fungal disease is 5 M (10% of the total population). Tinea capitis, recurrent vulvovaginitis and keratitis are estimated to affect 4,127,760, 631,261, and 6,552 patients, respectively. HIV-related mycosis is estimated to affect 5,945 oral candidiasis, 1,921 esophageal candidiasis, 571 Pneumocystis pneumonia, and 462 cryptococcal meningitis cases. Aspergillus infections are estimated as follow: 3,438 invasive aspergillosis, 14,950 chronic pulmonary aspergillosis, 67,860 allergic bronchopulmonary aspergillosis cases, while the prevalence of severe asthma with fungal sensitization and fungal rhinosinusitis was 86,860 and 93,600 cases, respectively. The neglected tropical disease eumycetoma was estimated to affect 16,837 cases with a rate of 36/100,000. Serious fungal infections are quite common in Sudan and require urgent attention to improve diagnosis, promote treatment, and develop surveillance programs.

Sarcoidosis is an idiopathic multiorgan disease with variable clinical outcomes. Comprehensive analysis of sarcoidosis mortality in US veterans is lacking. What are the trends in all-cause mortality among US veterans with sarcoidosis, and how are these trends influenced by demographics, Black vs White racial disparities, and geographic variability in relationship to mortality? Using Veterans Health Administration (VHA) electronic health records (EHRs), we conducted a population-based retrospective cohort study of adjusted all-cause mortality from 2004 through 2022 among veterans with a diagnosis of sarcoidosis who received care through the VHA. Demographics, region of residence, service branch, tobacco use, and comorbidities were extracted from the EHR. Annual trends in all-cause mortality and patient-level characteristics associated with mortality were examined with multivariable ungrouped Poisson regression. We visualized trends and analyzed state-by-state mortality using the marginal means procedure. In subgroup analysis (2015-2022), we considered the impact of neighborhood-level socioeconomic disparities using the Area Deprivation Index (ADI). In all, 23,745 veterans received a diagnosis of sarcoidosis between 2004 and 2019 and were followed up through 2022. After adjustment, including age and sex, all-cause mortality increased annually by 4.7% (P < .0001) and was 6.4% higher in Black than White veterans (mortality rate ratio, 1.064; P = .02). A subgroup analysis comparing models with and without ADI adjustment showed no meaningful change in mortality trends. Risk factors for increased all-cause mortality included older age, male sex, Black race, Northeast residence, and lower risk with other service branches. Despite distinct geographical variations in mortality rates, no clear patterns emerged. Mortality among veterans with sarcoidosis is rising. Differences identified by service branch and higher risk among male Veterans raise questions about differences in environmental exposures. The narrower racial disparities and smaller impact of ADI than in other studies may highlight the role of universal health care access in achieving equitable outcomes.

Background: Black men in the United States bear a disproportionate share of the prostate cancer (PCa) burden, with more than 50% higher incidence and double the mortality compared with White men. Previous studies have examined racial disparities in the incidence of fatal PCa (fPCa), defined as diagnosis leading to disease-specific death within 10 years, and found that they are greater in younger vs older men. However, the extent to which these trends are driven by disparities in incidence or survival is unknown. Methods: We conduct a retrospective analysis of data from the Surveillance, Epidemiology, and End Results program over the period 1980-2009 to decompose the incidence of fPCa into incidence and 10-year probability of death and quantify the relative disparities in these metrics by age at diagnosis. Findings: We find that relative PCa incidence for Black vs White men significantly decreases by 0.116 units with each successive 5-year age group (95% CI = −0.183 to −0.049) but the relative probability of death within 10 years does not differ significantly by age (slope = −0.012, 95% CI = −0.060 to 0.035). Further, this deconstruction is similar before and after the introduction of prostate-specific antigen screening. Conclusion: We conclude that higher relative incidence of fPCa in young Black men vs young White men appears to be largely driven by their significantly increased incidence of disease. This finding supports investigating targeted screening of Black men beginning at younger ages than White men.
