RESUMO

BACKGROUND: Health systems globally are investing in integrating secure messaging platforms for virtual care in clinical practice. Implementation science is essential for adoption, scale-up, spread and maintenance of complex evidence-based solutions in clinics with evolving priorities. In response, the mobile Health (mHealth) Research Group modified the existing consolidated framework for implementation research (CFIR) to evaluate implementation of virtual health tools in clinical settings. WelTel® is an evidence-based digital health platform widely deployed in various geographical and health contexts. The objective is to identify the facilitators and barriers for implementing WelTel and to assess the application of the mCFIR tool in facilitating focus groups in different geographical and health settings. METHODS: Both qualitative and descriptive quantitative approaches were employed. Six mCFIR sessions were held in three countries with 51 key stakeholders. The mCFIR tool consists of 5 Domains and 25 constructs and was distributed through Qualtrics Experience Management (XM). "Performance" and "Importance" scores were valued on a scale of 0 to 10 (Mean ± SD). Descriptive analysis was conducted using R computing software. NVivo 12 Pro software was used to analyze mCFIR responses and to generate themes from the participants' input. RESULTS: We observed a parallel trend in the scores of Importance and Performance. Of the five Domains, Domain 4 (End-user Characteristics) and Domain 3 (Inner Settings) scored highest in Importance (8.9 ± 0.5 and 8.6 ± 0.6, respectively) and Performance (7.6 ± 0.7 and 7.2 ± 1.3, respectively) for all sites. Domain 2 (Outer Setting) scored the lowest in both Importance and Performance for all sites (7.6 ± 0.4 and 5.6 ± 1.8). The thematic analysis produced the following themes: for areas of strengths, the themes brought up were timely diagnosis and response, cost-effectiveness, and user-friendliness. As for areas for improvement, the themes discussed were training, phone accessibility, stakeholder engagement, and literacy. CONCLUSION: The mCFIR tool allowed for a comprehensive understanding of the barriers and facilitators to the implementation, reach, and scale-up of digital health tools. Amongst several important findings, we observed the value of bringing the perspectives of both end users (HCPs and patients) to the table across Domains.

RESUMO

BACKGROUND: A randomized trial of voluntary medical male circumcision (MC) of HIV-infected men reported increased HIV transmission to female partners among men who resumed sexual intercourse prior to wound healing. We conducted a prospective observational study to assess penile HIV shedding after MC. METHODS AND FINDINGS: HIV shedding was evaluated among 223 HIV-infected men (183 self-reported not receiving antiretroviral therapy [ART], 11 self-reported receiving ART and had a detectable plasma viral load [VL], and 29 self-reported receiving ART and had an undetectable plasma VL [<400 copies/ml]) in Rakai, Uganda, between June 2009 and April 2012. Preoperative and weekly penile lavages collected for 6 wk and then at 12 wk were tested for HIV shedding and VL using a real-time quantitative PCR assay. Unadjusted prevalence risk ratios (PRRs) and adjusted PRRs (adjPRRs) of HIV shedding were estimated using modified Poisson regression with robust variance. HIV shedding was detected in 9.3% (17/183) of men not on ART prior to surgery and 39.3% (72/183) of these men during the entire study. Relative to baseline, the proportion shedding was significantly increased after MC at 1 wk (PRR = 1.87, 95% CI = 1.12-3.14, p = 0.012), 2 wk (PRR = 3.16, 95% CI = 1.94-5.13, p < 0.001), and 3 wk (PRR = 1.98, 95% CI = 1.19-3.28, p = 0.008) after MC. However, compared to baseline, HIV shedding was decreased by 6 wk after MC (PRR = 0.27, 95% CI = 0.09-0.83, p = 0.023) and remained suppressed at 12 wk after MC (PRR = 0.19, 95% CI = 0.06-0.64, p = 0.008). Detectable HIV shedding from MC wounds occurred in more study visits among men with an HIV plasma VL > 50,000 copies/ml than among those with an HIV plasma VL < 400 copies/ml (adjPRR = 10.3, 95% CI = 4.25-24.90, p < 0.001). Detectable HIV shedding was less common in visits from men with healed MC wounds compared to visits from men without healed wounds (adjPRR = 0.12, 95% CI = 0.07-0.23, p < 0.001) and in visits from men on ART with undetectable plasma VL compared to men not on ART (PRR = 0.15, 95% CI = 0.05-0.43, p = 0.001). Among men with detectable penile HIV shedding, the median log10 HIV copies/milliliter of lavage fluid was significantly lower in men with ART-induced undetectable plasma VL (1.93, interquartile range [IQR] = 1.83-2.14) than in men not on ART (2.63, IQR = 2.28-3.22, p < 0.001). Limitations of this observational study include significant differences in baseline covariates, lack of confirmed receipt of ART for individuals who reported ART use, and lack of information on potential ART initiation during follow-up for those who were not on ART at enrollment. CONCLUSION: Penile HIV shedding is significantly reduced after healing of MC wounds. Lower plasma VL is associated with decreased frequency and quantity of HIV shedding from MC wounds. Starting ART prior to MC should be considered to reduce male-to-female HIV transmission risk. Research is needed to assess the time on ART required to decrease shedding, and the acceptability and feasibility of initiating ART at the time of MC.

RESUMO

OBJECTIVE: Previous randomised trial data have demonstrated that male circumcision reduces Mycoplasma genitalium prevalence in men. We assessed whether male circumcision also reduces M genitalium infection in female partners of circumcised men. METHODS: HIV-negative men were enrolled and randomised to either male circumcision or control. Female partners of male trial participants from the intervention (n=437) and control (n=394) arms provided interview information and self-collected vaginal swabs that were tested for M genitalium by APTIMA transcription-mediated amplification-based assay. Prevalence risk ratios (PRR) and 95% CI of M genitalium prevalence in intervention versus control group were estimated using Poisson regression. Analysis was by intention-to-treat. An as-treated analysis was conducted to account for study-group crossovers. RESULTS: Male and female partner enrolment sociodemographic characteristics, sexual behaviours, and symptoms of sexually transmitted infections were similar between study arms. Female M genitalium prevalence at year 2 was 3.2% (14/437) in the intervention arm and 3.6% (14/394) in the control arm (PRR=0.90, 95% CI 0.43 to 1.89, p=0.78). In an as-treated analysis, the prevalence of M genitalium was 3.4% in female partners of circumcised men and 3.3% in female partners of uncircumcised men (PRR=1.01, 95% CI 0.48 to 2.12, p=0.97). CONCLUSIONS: Contrary to findings in men, male circumcision did not affect M genitalium infection in female partners.

RESUMO

OBJECTIVE: To assess completed wound healing after medical male circumcision (MMC) among human immunodeficiency virus (HIV)-negative and HIV-positive men with cluster of differentiation 4 (CD4) counts of <350 and ≥350 cells/mm(3) , as minimal data are available on the safety of MMC among HIV-positive men with low CD4 counts. PATIENTS AND METHODS: In all, 262 HIV-negative and 177 HIV-positive consenting males aged ≥12 years accepted MMC using the dorsal slit procedure and were enrolled in the study. Socio-demographic and behavioural data and blood for HIV testing and CD4 counts were collected at baseline. Participants were followed weekly to collect information on resumption of sex, condom use and both self-reported and clinically assessed wound healing. The proportions healed among HIV-positive men were compared with HIV-negative men. Time to complete wound healing was assessed by Kaplan-Meier survival analysis. RESULTS: There were no statistically significant differences in the proportion of men healed by HIV status. At 4 weeks, the proportions healed were 85.9% in HIV-negative men, 77.4% in HIV-positive men with a CD4 count of ≥350 cells/mm(3) and 87.1% in HIV-positive men with a CD4 count of <350 cells/mm(3) . The median time to healing was 4 weeks and did not vary by HIV or CD4 status. All men had certified complete wound healing at 6 weeks after MMC. In all, 1.4% of HIV-positive men with a CD4 count of <350 cells/mm(3) resumed sex before healing, compared with 8.5% among HIV-positive men with a CD4 count of ≥350 cells/mm(3) (P = 0.052) and 7.8% (P = 0.081) among HIV-negative men. CONCLUSION: Inclusion of HIV-positive men with low CD4 counts in MMC services is not deleterious to postoperative wound healing.

RESUMO

This paper builds on prior work exploring the use of risk-associated alternative healthcare (RAAH) in Canada. RAAH uptake was surveyed to explore the characteristics of adult RAAH users and the value of established psychometric instruments previously used in alternative healthcare studies in predicting RAAH behaviours: the Control Beliefs Inventory (CBI), the Reward Responsiveness Behavioural Activation System (RBAS) scale, the Positive Attitudes to Science (PAS) scale, the Satisfaction with Orthodox Medicine (SOM) scale, and the brief version of the Susceptibility to Persuasion-II (StP-II-B) scale. Findings suggest RAAH is influenced by gender, age, income, education, employment, chronic illness status, and ethnicity. Engagement in some form of RAAH was common (around 40%) and the most common types of RAAH use reported were physical manipulation and herbal/nutritional supplement use. Other higher-risk AH activities (such as use of toxins and physically invasive procedures) were also reported by about 5% of respondents. The StP-II-B and PAS instruments were predictive of the likelihood of engagement in RAAH behaviours, as illustrated by higher risk tolerance, desire for novelty, positive attitude to advertising and social influence, and positive beliefs about science. The CBI, RBAS, and SOM instruments were not predictive overall. However, the CBI and SOM instruments were predictive of engagement with physical manipulative RAAH activities, while the RBAS was predictive of herbal/nutritional RAAH engagement. These findings can help inform health professionals' understanding of public health-seeking behaviours with respect to risk.

RESUMO

Risk compensation associated with male circumcision has been a concern for male circumcision scale-up programs. Using posttrial data collected during 2007-2011 on 2,137 male circumcision trial participants who were uncircumcised at trial closure in Rakai, Uganda, the authors evaluated their sexual behavioral changes during approximately 3 years' follow-up after trial closure. Eighty-one percent of the men self-selected for male circumcision during the period, and their sociodemographic and risk profiles were comparable to those of men remaining uncircumcised. Linear models for marginal probabilities of repeated outcomes estimate that 3.3% (P < 0.0001) of the male circumcision acceptors reduced their engagement in nonmarital relations, whereas there was no significant change among men remaining uncircumcised. Significant decreases in condom use occurred in both male circumcision acceptors (-9.2% with all partners and -7.0% with nonmarital partners) and nonacceptors (-12.4% and -13.5%, respectively), and these were predominantly among younger men. However, the magnitudes of decrease in condom use were not significantly different between the 2 groups. Additionally, significant decreases in sex-related alcohol consumption were observed in both groups (-7.8% in male circumcision acceptors and -6.1% in nonacceptors), mainly among older men. In summary, there was no evidence of risk compensation associated with male circumcision among this cohort of men during 3 years of posttrial follow-up.

RESUMO

OBJECTIVE: To assess the safety and efficiency of the dorsal slit and sleeve male circumcision (MC) procedures performed by physicians and clinical officers (COs). PATIENTS AND METHODS: We evaluated the time required for the MC procedure (efficiency) and moderate/severe adverse events (AEs) for MC (safety) by trained physicians and COs using the sleeve and dorsal slit MC methods in a service programme. Univariate and multiple regressions with robust variance estimation were used to assess factors associated with operative duration (linear) and AEs (logistic). RESULTS: Six physicians and eight COs conducted 1934 and 3218 MCs, respectively; there were 2471 dorsal slit and 2681 sleeve MC procedures. The overall mean operative duration was 33 min for newly trained providers, which decreased to ≈20 min after ≈100 MCs. The adjusted mean operative duration for dorsal slit MC was significantly shorter than that for the sleeve MC method (Δ - 2.7 min, P < 0.001). The operative duration was longer for COs than physicians for the sleeve procedure, but not the dorsal slit procedure; however this difference reduced with increasing numbers of MCs completed. The unadjusted AE rates were 0.6% for dorsal slit MC and 1.4% for the sleeve method (P = 0.006) and 1.5% for physicians and 0.68% for COs (P = 0.003); however, there were no significant differences after multivariate adjustment. Use of bipolar cautery significantly reduced operative duration (Δ - 4.0 min, P = 0.008), but was associated with higher AE rates (adjusted odds ratio 2.13, 95% confidence interval 1.26-3.61, P = 0.005). CONCLUSION: The dorsal slit MC method is faster than sleeve resection, and can be safely performed by non-physicians; however, use of bipolar cautery may be inadvisable in this setting.

RESUMO

OBJECTIVE: To assess self-reported pain control during and after surgery with a mixture of lignocaine and bupivacaine compared with lignocaine alone among male circumcision (MC) service recipients in Rakai, Uganda. PATIENTS AND METHODS: The two formulations of local anaesthesia for MC were used alternatively at weekly intervals in 360 patients; 179 received lignocaine alone and 181 received the lignocaine and bupivacaine mixture (LBmix). The proportions of men reporting pain during or after surgery, and the need for additional anaesthesia during surgery were determined for the LBmix vs lignocaine using Poisson adjusted rate ratios (RRs). Characteristics including age, weight, surgeon (medical officer vs clinical officer), surgical method and duration of surgery were compared between the arms using two-sample t-tests and chi-square tests. RESULTS: Patient and provider characteristics were comparable between the two anaesthetic groups. A higher proportion of patients reported pain during surgery in the lignocaine group (adjusted RR 11.6, 95% confidence interval [CI] 3.5-37.9, P < 0.001), required additional anaesthesia (adjusted RR 4.8, 95% CI 1.4-17.1, P = 0.015), and were more likely to report pain during the immediate postoperative period (adjusted RR 3.4, 95% CI 2.3-5.0, P < 0.001). These differences were particularly marked among patients with MC times longer than the median (adjusted RR 13.4, 95% CI 3.1-57.0, P < 0.001). CONCLUSION: The LBmix significantly reduced pain associated with MC and the need for additional anaesthesia during MC.

RESUMO

Defining alternative health care and the recording of associated adverse events and harm remains problematic. This Canadian study aimed to establish and classify risk-associated alternative health practices in a Delphi study undertaken with an interdisciplinary panel of 17 health experts in 2020. It provides a new functional definition of alternative health care and an initial taxonomy of risk-associated alternative health care practices. A number of risk-associated practices were identified and categorized into general practices that conflict with biomedical care or largely untested therapies, alternative beliefs systems, physical manipulative alternative therapies, and herbal and nutritional supplements. Some risk significant harms including major physical injuries or even death. The lack of systematic methods for recording adverse events in alternative health care makes establishing the frequency of such events challenging. However, it is important that people engaging with alternative health care understand they are not necessarily risk-free endeavours, and what those risks are.

RESUMO

BACKGROUND: In late 2010, Uganda introduced a supervision, performance assessment, and recognition strategy (SPARS) to improve staff capacity in medicines management in government and private not-for-profit health facilities. This paper assesses the impact of SPARS in health facilities during their first year of supervision. METHODS: SPARS uses health workers trained as Medicines Management Supervisors (MMS) to supervise health facilities and address issues identified through indicatorbased performance assessment in five domains: stock management, storage management, ordering and reporting, prescribing quality, and dispensing quality. We used routine data generated during SPARS visits to 1222 health facilities to evaluate performance changes during the first year of supervision as well as the time until achieving an adequate score in this period. We also explored variables related to facilities, MMS, and intensity of implementation as predictors of performance improvement and time until achieving an adequate score. RESULTS: Health facilities received an average of 3.4 MMS visits during the first year of supervision, with an average of 88 days between visits; each MMS implemented a median of 28 visits per year. Overall SPARS scores (maximum of 25) improved by 2.3 points (22.3%) per visit from a mean baseline score of 10.3. The adjusted improvement in overall SPARS score was significantly higher in primary health care facilities (2.36) versus higher-level health facilities and hospitals (2.15) (p = 0.001). The incremental improvement was highest at visit 2, with decreasing but continuing positive gains in subsequent visits. The adjusted mean incremental improvement per visit was highest in the prescribing quality domain, followed by dispensing quality, ordering and reporting, stock management, and storage management. Adjusted improvement in SPARS scores varied by region, year of implementation, and facility ownership. After one year of SPARS, 22% of facilities achieved an adequate score of 18.75 (75% of maximum score). CONCLUSIONS: SPARS was effective in building health facility capacity in medicines management, with a median overall improvement of almost 70% during the first year. The greatest improvements occurred in prescribing quality and at lower levels of care, although the highest level of performance was achieved in storage management. We recommend broad dissemination of the SPARS approach in all Ugandan health facilities as well as in other countries seeking a practical strategy to improve medicines management performance.

RESUMO

BACKGROUND: Since its inception, the Uganda National Drug Authority (NDA) has regularly inspected private sector pharmacies to monitor adherence to Good Pharmacy Practices (GPP). This study reports findings from the first public facility inspections following an intervention (SPARS: Supervision, Performance Assessment, and Recognition Strategy) to build GPP and medicines management capacity in the public sector. METHODS: The study includes 455 public facilities: 417 facilities were inspected after at least four SPARS visits by trained managerial district staff (SPARS group), 38 before any exposure to SPARS. NDA inspectors measured 10 critical, 20 major, and 37 minor GPP indicators in every facility and only accredited facilities that passed all 10 critical and failed no more than 7 major indicators. Lack of compliance for a given indicator was defined as less than 75 % facilities passing that indicator. We assessed factors associated with certification using logistic regression analysis and compared number of failed indicators between the SPARS and comparative groups using two sample t-tests with equal or unequal variance. RESULTS: 57.4 % of inspected facilities obtained GPP certification: 57.1 % in the SPARS and 60.5 % in the comparative group (Adj. OR = 0.91, 95 % CI 0.45-1.85, p = 0.802). Overall, facilities failed an average of 10 indicators. SPARS facilities performed better than comparative facilities (9 (SD 6.1) vs. 13 (SD 7.7) failed indicators respectively; p = 0.017), and SPARS supported facilities scored better on indicators covered by SPARS. For all indicators but one minor, performance in the SPARS group was equal to or significantly better than in unsupervised facilities. Within the SPARS (intervention) group, certified facilities had < 75 % compliance on 7 indicators (all minor), and uncertified facilities on 19 (4 critical, 2 major, and 13 minor) indicators. CONCLUSIONS: Half of the Ugandan population obtains medicines from the public sector. Yet, we found only 3/5 of inspected public health facilities meet GPP standards. SPARS facilities tended to perform better than unsupervised facilities, substantiating the value of supporting supervision interventions in GPP areas that need strengthening. None compliant indicators can be improved through practices and behavioral changes; some require infrastructure investments. We conclude that regular NDA inspections of public sector pharmacies in conjunction with interventions to improve GPP adherence can revolutionize patient care in Uganda.

RESUMO

Individuals who communicate their HIV diagnosis to sexual partners may be at increased risk of intimate partner violence (IPV). The authors examined past year self-reported IPV associated with communication of HIV diagnosis and other factors, in a sample of 679 sexually active; HIV-positive individuals age 18 to 49, who received HIV results and posttest counselling 12 months or more prior to the survey in Rakai, Uganda, using log-binomial multivariable regression. The rates of verbal and physical abuse among married individuals were significantly higher compared to unmarried persons, respectively. Physical abuse was significantly higher among women compared to men. IPV was not significantly associated with communication of HIV diagnosis. Interventions to prevent IPV among married HIV-positive individuals particularly women, at the community level, are needed.

RESUMO

Background. Data on the incidence of Trichomonas vaginalis and use of hormonal contraception (HC) are limited. Methods. 2,374 sexually active women aged 15-49 years from cohort surveys in Rakai, Uganda, were included. Incidence of T. vaginalis was estimated per 100 person years (py) and association between HC (DMPA, Norplant, and oral contraceptives) and T. vaginalis infection was assessed by incidence rate ratios (IRR), using Poisson regression models. Results. At baseline, 34.9% had used HC in the last 12 months, 12.8% HIV+, 39.7% with high BV-scores (7-10), and 3.1% syphilis positive. The 12-month incidence of T. vaginalis was 2.4/100 py; CI (1.90, 3.25). When stratified by type of HC used, compared to women who did not use HC or condoms, incidence of T. vaginalis was significantly higher among users of Norplant (adj.IRR = 3.01, CI: 1.07-8.49) and significantly lower among DMPA users (adj.IRR = 0.55, CI: 0.30, 0.98) and women who discontinued HC use at follow-up (adj.IRR = 0.30, CI: 0.09, 0.99). HIV infection was associated with an increase in incidence of T. vaginalis (adj.IRR = 2.34, CI: 1.44, 3.78). Conclusions. Use of Norplant and being HIV+ significantly increased the risk of T. vaginalis, while use of DMPA and discontinuation of overall HC use were associated with a decreased incidence of T. vaginalis.

RESUMO

OBJECTIVE: To assess the accuracy of PIMA Point-of-Care (POC) CD4 testing in rural Rakai, Uganda. METHODS: 903 HIV positive persons attending field clinics provided a venous blood sample assessed on site using PIMA analyzers per manufacturer's specifications. The venous samples were then run on FACSCalibur flow cytometry at a central facility. The Bland-Altman method was used to estimate mean bias and 95% limits of agreement (LOA). Sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) were calculated for a CD4 threshold of <350 and <500 cells/uL for antiretroviral eligibility. RESULTS: There was a high correlation between PIMA and FACSCalibur CD4 counts (r = 0.943, p<0.001). Relative to FACSCalibur, the PIMA POC CD4 had negative mean bias of -34.6 cells/uL (95% LOA: -219.8 to 150.6) overall. The dispersion at CD4<350 cells/uL was 5.1 cells/uL (95% LOA: -126.6 to 136.8). For a threshold of CD4<350 cells/uL, PIMA venous blood had a sensitivity of 88.6% (95%CI 84.8-92.4%), specificity of 87.5% (95%CI 84.9-90.1%), NPV of 94.9% (95%CI 93.1-96.7%), and PPV of 74.4% (95%CI 69.6-79.2%). PIMA sensitivity and PPV significantly increased to 96.1% and 88.3% respectively with increased threshold of 500 cells/uL. CONCLUSIONS: Overall, PIMA POC CD4 counts demonstrated negative bias compared to FACSCalibur. PIMA POC sensitivity improved significantly at a higher CD4 threshold of 500 than a 350 cells/uL threshold.

RESUMO

OBJECTIVE: To assess the safety of medical male circumcision (MMC) among human immunodeficiency virus (HIV)-infected men with CD4 levels <350 cells/mm(3), CD4 counts ≥ 350 cells/mm(3), and HIV-negative men. METHODS: Two hundred forty-two HIV-infected men and a sample of 262 HIV-negative consenting men aged 12 years or older who requested free MMC were enrolled in a prospective study. Blood for HIV testing and a CD4 count were collected before surgery. During weekly follow-up over 6 weeks, data were collected on wound healing and adverse events (AEs) by examination, and resumption of sex and condom use ascertained by interview. Surgery-related AEs were characterized by type, severity, management, and resolution. Chi-square and Fisher's exact tests were used to test for differences in AE proportions. RESULTS: Overall, only 2 of the 453 men experienced moderate AEs, a rate of 0.44 per 100 surgeries. No AE occurred among HIV-negative men, whereas the AE rate among HIV-infected men with CD4 counts ≥ 350 cells/mm(3) was 0.79 per 100 surgeries, and among men with CD4 counts <350 cells/mm(3) the rate was 1.19 per 100 surgeries (P = .214). AE rates were comparable for all characteristics (P >.05). CONCLUSION: HIV-positive men can be safely included in MMC roll out programs without necessitating presurgery CD4 counts determination.

RESUMO

OBJECTIVES: To assess the safety and acceptance of the PrePex device for medical male circumcision (MMC) in rural Uganda. METHODS: In an observational study, HIV-uninfected, uncircumcised men aged 18 and older who requested elective MMC were informed about the PrePex and dorsal slit methods and offered a free choice of their preferred procedure. 100 men received PrePex to assess preliminary safety (aim 1). An additional 329 men, 250 chose PrePex and 79 chose Dorsal slit, were enrolled following approval by the Safety Monitoring Committee (aim 2). Men were followed up at 7 days to assess adverse events (AEs) and to remove the PrePex device. Wound healing was assessed at 4 weeks, with subsequent weekly follow up until completed healing. RESULTS: The PrePex device was contraindicated in 5.7% of men due to a tight prepuce or phimosis/adhesions. Among 429 enrolled men 350 (82.0%) got the PrePex device and 79 (18.0%) the dorsal slit procedure. 250 of 329 men (76.0%) who were invited to choose between the 2 procedures chose Prepex. There were 9 AEs (2.6%) with the PrePex, of which 5 (1.4%) were severe complications, 4 due to patient self-removal of the device leading to edema and urinary obstruction requiring emergency surgical circumcision, and one due to wound dehiscence following device removal. 71.8% of men reported an unpleasant odor prior to PrePex removal. Cumulative rates of completed wound healing with the PrePex were 56.7% at week 4, 84.8% week 5, 97.6% week 6 and 98.6% week 7, compared to 98.7% at week 4 with dorsal slit (p<0.0001). CONCLUSION: The PrePex device was well accepted, but healing was slower than with dorsal slit surgery. Severe complications, primarily following PrePex self-removal, required rapid access to emergency surgical facilities. The need to return for removal and delayed healing may increase Program cost and client burden.

RESUMO

BACKGROUND: Medical male circumcision (MC) of HIV-infected men may increase plasma HIV viral load and place female partners at risk of infection. We assessed the effect of MC on plasma HIV viral load in HIV-infected men in Rakai, Uganda. METHODS: 195 consenting HIV-positive, HAART naïve men aged 12 and above provided blood for plasma HIV viral load testing before surgery and weekly for six weeks and at 2 and 3 months post surgery. Data were also collected on baseline social demographic characteristics and CD4 counts. Change in log10 plasma viral load between baseline and follow-up visits was estimated using paired t tests and multivariate generalized estimating equation (GEE). RESULTS: Of the 195 men, 129 had a CD4 count ≧ 350 and 66 had CD4 <350 cells/mm3. Men with CD4 counts <350 had higher baseline mean log10 plasma viral load than those with CD4 counts ≧ 350 cells/mm3 (4.715 vs 4.217 cps/mL, respectively, p = 0.0005). Compared to baseline, there was no statistically significant increase in post-MC HIV plasma viral loads irrespective of CD4. Multivariate analysis showed that higher baseline log10 plasma viral load was significantly associated with reduction in mean log10 plasma viral load following MC (coef.  = -0.134, p<0.001). CONCLUSION: We observed no increase in plasma HIV viral load following MC in HIV-infected, HAART naïve men.

RESUMO

BACKGROUND: The risk of HIV associated with hormonal contraceptives is controversial. We assessed hormonal contraceptive use and HIV incidence in HIV-discordant couples in Rakai, Uganda. METHODS: HIV-discordant couples were retrospectively identified from a cohort between 1999 and 2009. Hormonal contraception included oral contraception, depomedroxyprogesterone acetate (DMPA), and implants (Norplant). Poisson regression estimated adjusted incidence rate ratios (adjIRRs) associated with hormonal contraceptive methods. A case-control subanalysis estimated odds ratios (ORs) of HIV associated with hormonal contraceptive, adjusted for viral load and age. RESULTS: We identified 190 male HIV-positive/female HIV-negative (M+F-) and 159 male HIV- negative/female HIV-positive (M-F+) couples not using antiretroviral therapy or condoms. Female HIV incidence was 5.8/100 person-years (py) among nonhormonal contraceptive users, 12.0/100 py among oral contraceptive users [adjIRR 2.65, 95% confidence interval (CI) 0.82-8.60], 4.5 among Norplant users (adjIRR: 0.89, 95% CI 0.11-7.10), and 7.5/100 py among DMPA users (adjIRR 1.42, 95% CI 0.60-3.36). Male HIV incidence was 7.4/100 py during nonhormonal contraceptive use, 16.5/100 py during female oral contraceptive use (adjIRR 2.52, 95% CI 0.49-12.95), and 4.9/100 py with DMPA use (adjIRR 0.57, 95% CI 0.19-1.70). The number of female seroconverters was three among oral contraceptive users, one among Norplant users, and seven among DMPA users. Male seroconverters were two during female oral contraceptive use, none with Norplant use, and three with DMPA use. In a nested case-control analysis after adjustment for HIV viral load, the adjOR associated with oral contraceptive use was 1.59 (95% CI 0.32-97.85) for M+F- and 2.11 (95% CI 0.18-25.26) for M-F+ couples. For DMPA use, the adjOR was 1.44 (95% CI 0.46-4.51) for M+F- and 1.40 (95% CI 0.30-6.49) for M-F+ couples. CONCLUSION: We did not observe significant risk of HIV acquisition or transmission with oral contraceptives or DMPA use in HIV discordant couples, but several point estimates were above 1.0 and statistical power was limited.

RESUMO

OBJECTIVES: Medical male circumcision (MMC) is recommended for HIV prevention in men. We assessed the acceptability and safety of the Shang Ring device compared with those of the dorsal slit method. METHODS: HIV-negative, uncircumcised men aged 18 years or older who requested free MMC services in rural Rakai, Uganda, were informed about the Shang Ring and dorsal slit procedures and offered a free choice of procedure. Men were followed at 7 days postoperatively to assess adverse events related to surgery and to remove the Shang Ring. Wound healing was assessed at 4 weeks postoperatively. RESULTS: Six hundred twenty-one men were enrolled, of whom 508 (81.8%) chose the Shang Ring and 113 the dorsal slit. The Shang Ring was provided to 504 men, among whom there were 4 failures of Ring placement (0.8%) that required surgical hemostasis and wound closure. Five hundred men received the Shang Ring and postoperative surgery-related moderate adverse events were 1.0%, compared with 0.8% among dorsal slit recipients. Complete wound healing at 4 weeks was 84% with the Ring and 100% with the dorsal slit (P < 0001). Resumption of intercourse before 4 weeks was 7.0% with the Ring and 15.0% with the dorsal slit (P = 0.01.) The mean time for surgery was 6.1 minutes with the Ring and 17.7 minutes with the dorsal slit. The mean time for Ring removal was 2.2 minutes. CONCLUSIONS: The Shang Ring is highly acceptable and safe in this setting, and could improve the efficiency of MMC services. However, back-up surgical services are needed in cases of Ring placement failures.

RESUMO

Rapid HIV tests are a crucial component of HIV diagnosis in resource limited settings. In Uganda, the Ministry of Health allows both serial and parallel HIV rapid testing using Determine, Stat-Pak and Uni-Gold. In serial testing, a non-reactive result on Determine ends testing. The performance of serial and parallel algorithms with Determine and Stat-Pak test kits was assessed. A cross-sectional diagnostic test accuracy evaluation using three rapid HIV test kits as per the recommended parallel test algorithm was followed by EIA-WB testing with estimates of the performance of serial testing algorithm. In 2520 participants tested by parallel rapid algorithms, 0.6% had weakly reactive result. Parallel testing had 99.7% sensitivity and 99.8% specificity. If Stat-Pak was used as the first screening test for a serial algorithm, the sensitivity was 99.6% and specificity was 99.7%. However, if Determine was used as the screening test, sensitivity was 97.3% and specificity was 99.9%. Serial testing with Stat-Pak as the initial screening test performed as well as parallel testing, but Determine was a less sensitive screen. Serial testing could be cost saving.
