Condom Use Among Male Sex Workers With Their Male Clients in Mombasa, Kenya: Results of a Sub-analysis of a Pilot, Multilevel, Structural, HIV Risk-Reduction Intervention

ABSTRACT

Despite the advent of preexposure prophylaxis, consistent condom use continues to be recommended because preexposure prophylaxis does not prevent sexually transmitted infections. This is important for high-risk populations (e.g., male sex workers; MSW) in low-resource, high-HIV/sexually transmitted infection prevalence settings, such as the Mombasa region in Kenya. This study aimed to examine the relationship between MSW's condom use, and their knowledge, beliefs, and attitudes about condoms. MSW (N = 158) completed surveys on their sexual behaviors/practices/attitudes. We used multiple regressions to identify associations between condom use, HIV knowledge/attitudes, and self-efficacy. Three quarters of participants reported always using condoms in the past week, and 64.3% reported always using condoms in the past month with male clients. Mean scores for knowledge and attitudes/self-efficacy toward condoms/safer sex were positively associated with condom use. Interventions to build self-efficacy, such as condom negotiation, and/or bringing up condom use with clients may be useful for Kenyan MSW.

The "Just Right" Amount of Oxygen. Improving Oxygen Use in a Rwandan Emergency Department

Rationale: Despite oxygen's classification as an essential medication by the World Health Organization, it is inconsistently available in many resource-constrained settings. Hypoxemia is associated with increased mortality, and mounting evidence suggests that hyperoxia may also be associated with adverse outcomes.Objectives: To determine if overuse of oxygen for some patients in a Rwandan tertiary care hospital emergency department might coexist with oxygen shortages and underuse of oxygen for other patients, and whether an educational intervention coupled with provision of pulse oximeters could improve the distribution of limited oxygen resources.Methods: We screened all patients in the adult emergency department (ED) of the University Teaching Hospital of Kigali for hypoxemia and receipt of oxygen therapy for 5 weeks. After completing baseline data collection, we provided pulse oximeters and conducted a didactic training with pre- and posttests on oxygen titration, with a chosen target oxygen saturation (Sp_O2) of 90% to 95%. Four and 12 weeks after the intervention, we evaluated all patients in the ED again for Sp_O2 and receipt of oxygen therapy for 4 weeks each period. We also recorded ED oxygen use and availability of reserve oxygen for the hospital during the three study periods.Results: During all data collection periods, 214 of 1,765 (12.1%) unique patients screened were hypoxemic. The proportion of patient-days with appropriately titrated oxygen therapy (Sp_O2, 90-95%) increased from 18.7% at baseline to 38.5% and 42.0% at 4 and 12 weeks postintervention (P < 0.001). On a multiple-choice examination testing knowledge of appropriate oxygen titration, clinicians' scores improved from average 60% (interquartile range [IQR], 40-80%) correct to 80% (IQR, 60-80%) correct immediately after the educational intervention (P < 0.001). Oxygen use in the ED decreased from a median of 32.0 (IQR, 28.0-35.0) tanks per day to 25.5 (IQR, 24.0-29.0) and 16.0 (IQR, 12.5-21.0) tanks per day at Weeks 4 and 12, respectively (P < 0.001), and the median daily number of tanks in reserve for the hospital appeared to increase, although this did not reach statistical significance (30.0 [IQR, 9.0-46.0], 86.5 [IQR, 74.0-92.0], and 75.5 [IQR, 8.5-88.5], respectively; P = 0.07).Conclusions: Among patients in a Rwandan adult ED, 12.1% of patients were hypoxemic and 81.3% of patient-days were either under- or overtreated with oxygen during baseline data collection on the basis of our defined target of Sp_O2 90% to 95%. Follow-up results at 4 and 12 weeks postintervention demonstrated sustained improvement in oxygen titration and likely increased availability of oxygen resources.

Colonic Volvulus: An Experience at Tertiary Care Hospital in Nepal

Introduction: Colonic volvulus is not an uncommon cause of large bowel obstruction. Limited research has been done about colonic volvulus in our part of the world which has been regarded as "volvulus belt." The aim of this study is to evaluate the clinical features, management, and factors affecting perioperative outcomes in patients with colonic volvulus.

Methods: A retrospective review of medical records of all patients managed for colonic volvulus in Universal College of Medical Sciences, Bhairahawa from January 2012 to December 2016 was done. Data on patient demographics, clinical course, methods of treatment, and outcomes were analyzed.

Results: A total of 62 patients (46 males) were studied. Mean age was 57.9 ± 10.4 years. The most common site involved was sigmoid (85.5%). The diagnosis was made by abdominal x-rays in 39 patients (62.2%), CT scan in 13 patients (21%), and laparotomy in 10 patients (16.1%). Fifty-eight patients (93.5%) were treated surgically. Resection and ostomy was the commonest operation performed in 30 patients (48.7%) followed by resection with anastomosis in 24 patients (38.7%). The overall complication was 38.7%. There were 9.7% of deaths. In multivariate analysis, age ( ≥ 60 years) (odds ratio (OR); 27.0, confidence interval (CI); (1.92-403), P; 0.01), preoperative hypotension (systolic blood pressure <90 mmHg) (OR; 7.82, CI; (1.19-51.2), P; 0.03), and gangrenous bowel (OR; 76.7, CI (3.60-1632), P; 0.005) were significant predictors of postoperative complications .

Conclusions: Volvulus of the colon is common in males and constipation is being commonest risk factors for volvulus. Surgeons should have a high index of suspicion and should be aware of these problems to make the early diagnosis with prompt treatment and to ensure better patient outcomes in volvulus endemic areas like ours.

Intersections Between Systems Thinking and Market Shaping for Assistive Technology: The SMART (Systems-Market for Assistive and Related Technologies) Thinking Matrix

The Sustainable Development Goals (SDGs) aspire to “leave no-one behind”. Universal access to assistive products is a critical link between the realization of the SDGs and those most likely to be left behind. However, assistive technology provision in many countries, particularly low- and middle-income countries, has traditionally been conducted through small-scale local providers, manufacturing products of varying degrees of quality at a limited price range. An effective way to scale these production and provision enterprises to the required level is needed to close the gap between available and required assistive technology. We argue that better access to assistive technology will only be realized through the adoption of a far stronger systems thinking and market shaping approach. We undertook a rapid literature review to explore the relationship between market shaping and assistive technology. Based on our review, we present an emergent framework for conceptualizing intersections between systems thinking and market shaping for assistive technology—the SMART (Systems-Market for Assistive and Related Technologies) Thinking Matrix.

The role of Ecstasy (MDMA) in managing intimacy and conflict in stable relationships

This paper discusses motivations for the use of MDMA among young adults in intimate relationships living in resource poor environments, where structural constraints limit potential for economic mobility and impact upon interpersonal relations. Drawing from in-depth interviews with men and women in intimate relationships with one or more partners, we report the range of motivations for MDMA use and their association with indicators of relationship quality, specifically trust and romantic exclusivity. Findings demonstrate that both men and women use MDMA primarily for the purpose of sexual enjoyment. However, men report the use of MDMA for sexual enjoyment more often, while women more frequently report the use of MDMA to compensate for psychological or physical displeasure, particularly in relationships characterised by distrust. We discuss how these motivations to use MDMA are shaped by gender norms and larger contextual and socio-economic factors and conclude with a call for more relational and sexual counselling opportunities for urban young adults to avoid MDMA use for self-medication.

Psychological interventions for post-traumatic stress disorder in people living with HIV in Resource poor settings: a systematic review

OBJECTIVE

Post-traumatic stress disorder is pervasive in low- and middle-income countries. There is evidence to suggest that post-traumatic stress disorder is more common among people living with HIV than non-infected matched controls. We carried out a systematic review of interventions for adult post-traumatic stress disorder from resource poor settings with a focus on people living with HIV.

METHODS

We included all studies that investigated interventions for adult post-traumatic stress disorder from resource poor settings with a focus on interventions that were either randomised controlled trials or observational cohort studies carried out from 1980 to May 2015.

RESULTS

Of the 25 articles that were identified for full review, two independent reviewers identified seven studies that met our study inclusion criteria. All randomised controlled trials (RCT) (n = 6) used cognitive behavioural therapy-based interventions and focused on people living with HIV in resource poor settings. There was only one study focusing on the use of lay counsellors to address post-traumatic stress disorder but core competencies were not described. There were no intervention studies from Africa, only an observational cohort study from Rwanda.

CONCLUSION

Rigorously evaluated interventions for adult post-traumatic stress disorder in people living with HIV are rare. Most were undertaken in resource poor settings located in high-income countries. There is a need for research on the development and implementation of appropriate interventions for post-traumatic stress disorder in people living with HIV in low- and middle-income countries.
