RESUMEN

For women living with HIV (WLH) in serodiscordant partnerships, decisions about childbearing can challenge condom use and antiretroviral adherence. In a prospective cohort of 148 WLH in serodiscordant partnerships, 58 (39%) wanted more children in the future but were not currently trying to conceive (fertility desire), and 32 (22%) were currently trying to become pregnant (fertility intent). Detection of prostate specific antigen (PSA) in vaginal secretions, a marker for recent condomless sex, was lowest in women with fertility desire and highest in women with fertility intent. Detectable viral load followed a similar pattern. Risk of HIV transmission, when condomless sex and PSA detection occurred concurrently, was three to fourfold higher at visits with fertility intent compared to visits with fertility desire. Qualitative interviews underscored the importance women place on childbearing and suggested that they had limited information about the role of antiretroviral therapy in reducing sexual HIV transmission.

RESUMEN

The relationships between depressive symptoms, viral suppression, and condomless sex were examined in a prospective cohort study of 369 HIV-positive Kenyan female sex workers. Participants were screened for depressive symptoms at baseline and every six months until completion of the study (up to 66 months). HIV viral load (VL) was measured every six months and prostate specific antigen (PSA) testing in vaginal secretions was performed quarterly. Mild or greater depressive symptoms were found in 100 (27.1%) women and were associated with increased risk of detectable VL (aRR 1.41, 95%CI 0.97-2.07, p-value = 0.07), but were not associated with detectable PSA. The co-occurrence of PSA detection and detectable VL at the same visit suggests the potential for HIV transmission but was uncommon (2.4% of visits). The prevalence of depressive symptoms and the association with detectable VL suggests the need for screening and treatment of depression for comprehensive HIV care in this population.

RESUMEN

BACKGROUND: Understanding the burden of common mental health disorders, such as depressive disorder, is the first step in strengthening prevention and treatment in humanitarian emergencies. However, simple random sampling methods may lead to a high risk of coercion in settings characterized by a lack of distinction between researchers and aid organizations, mistrust, privacy concerns, and the overarching power differential between researchers and populations affected by crises. This case analysis describes a sampling approach developed for a survey study of depressive disorder in a Syrian refugee camp in Greece (n = 135). DISCUSSION: Syrian refugees face an extraordinarily high burden of depressive disorder during the asylum process (43%), necessitating population screening, prevention, and treatment. In order to preserve the informed consent process in this refugee camp setting, the research team developed a two-phase sampling strategy using a map depicting the geographical layout of the housing units within the camp. In the first phase, camp management announced a research study was being undertaken and individuals were invited to volunteer to participate. The participants' container (housing) numbers were recorded on the map, but were not linked to the survey data. Then, in the second phase, the camp map was used for complementary sampling to reach a sample sufficient for statistical analysis. As a result of the two phases of the sampling exercise, all eligible adults from half the containers in each block were recruited, producing a systematic, age- and sex-representative sample. CONCLUSIONS: Combining sampling procedures in humanitarian emergencies can reduce the risk of coerced consent and bias by allowing participants to approach researchers in the first phase, with a second phase of sampling conducted to recruit a systematic sample. This case analysis illuminates the feasibility of a two-phase sampling approach for drawing a quasi-random, representative sample in a refugee camp setting.

RESUMEN

This prospective study of HIV-positive Kenyan women in serodiscordant couples examined relationships between psychosocial factors, viral suppression, and condomless sex. Participants were screened for alcohol use disorders and intimate partner violence (IPV) annually and depressive symptoms every 6 months. Prostate specific antigen (PSA) detection was used as a marker for condomless sex. A total of 151 participants contributed 349 person-years of follow-up. Hazardous/harmful alcohol use was associated with increased risk of detecting PSA in vaginal secretions (aRR 1.99, 95%CI 1.08-3.66, χ2 = 4.85 (1)), while IPV and depression were not. Events representing HIV transmission potential, where there was biological evidence of condomless sex at a visit with a detectable plasma viral load, were observed at 2% of visits. The high prevalence of IPV and association between alcohol use and sexual risk suggest the need for monitoring and support for these conditions as part of comprehensive HIV care for women.

RESUMEN

BACKGROUND: Despite the need for mental health surveillance in humanitarian emergencies, there is a lack of validated instruments. This study evaluated a sequential screening process for major depressive disorder (MDD) using the two- and eight-item Patient Health Questionnaires (PHQ-2 and PHQ-8, respectively). METHODS: This study analyzed data collected during a cross-sectional survey in a Syrian refugee camp in Greece (n = 135). The response rate for each instrument was assessed, and response burden was calculated as the number of items completed. The sequential screening process was simulated to replicate the MDD classifications captured if the PHQ-2 was used to narrow the population receiving the full PHQ-8 assessment. All respondents were screened using the PHQ-2. Only respondents scoring ≥ 2 are considered at risk for symptoms of MDD and complete the remaining six items. The positive and negative percent agreement of this sequential screening process were evaluated. RESULTS: The PHQ-2, PHQ-2/8 sequential screening process, and PHQ-8 were completed by 91%, 87%, and 84% of respondents, respectively. The sequential screening process had a positive percent agreement of 89% and a negative percent agreement of 100%, and eliminated the need to complete the full PHQ-8 scale for 34 (25%) respondents. CONCLUSIONS: The benefits of the sequential screening approach for the classification of MDD presented here are twofold: preserving classification accuracy relative to the PHQ-2 alone while reducing the response burden of the PHQ-8. This sequential screening approach is a pragmatic strategy for streamlining MDD surveillance in humanitarian emergencies.

RESUMEN

BACKGROUND: Over one million Syrian asylum seekers have travelled to Greece with the ultimate aim of reaching other countries in western Europe. Depression prevalence and associated sociodemographic and displacement characteristics have been reported for resettled migrants. However, the prevalence of major depressive disorder (MDD) and its risk factors have not been described among migrants engaged in the asylum process ensuing from the Syrian crisis. This study provides new data about the mental health status of migrants in transition in the context of protracted asylum procedures. METHODS: We conducted a cross-sectional survey in a Syrian refugee camp in the Attica region of Greece from January 16-31, 2017. Individuals ≥18 years of age with verbal Arabic or English language skills were eligible to participate. The Patient Health Questionnaire-8 (PHQ-8), an eight-item validated diagnostic and severity measure, was used to screen for MDD. We analysed the relationships between MDD and sociodemographic and displacement characteristics using multivariable logistic regression. RESULTS: A total of 135 surveys were completed, representing 40% of the adult population in the refugee camp. The mean age of the participants was 30 years (18-61 years); women comprised 41% of the sample; 74% of the participants had ever married; 67% had children; and 33% of participants had not attended secondary school, including 11% who had never attended school. Median time since departing the country of origin was 12 months (< 1-74 months). Median time spent in the asylum process in Greece was 10 months (< 1-49 months). MDD was detected in 44% (95% CI: 37-50) of participants. Being a woman (Adjusted Odds Ratio [AOR]: 3.23, p = 0.019), each additional child (AOR: 1.61, p = 0.006), and increased time in the asylum process in Greece (AOR: 1.15, p = 0.043) were significant risk factors for MDD. Ever being married was associated with reduced odds of MDD (AOR: 0.23, p = 0.042). CONCLUSIONS: Syrian migrants face an extraordinarily high burden of MDD as they seek asylum. Incorporation of screening and treatment into service provision within refugee camps is urgently needed, particularly as migrants spend extended periods of time in transition due to protracted asylum procedures.

RESUMEN

INTRODUCTION: Medical facilities are civilian objects specially protected during armed conflict by international humanitarian law (IHL). These protections are customarily applied regardless of the conflict, parties or contexts involved. Attacks on medical care have characterised the bombardment campaign of the Gaza Strip beginning 7 October 2023. This study presents evidence regarding patterns of damage to medical complexes relative to all other buildings in the first month of this conflict. METHODS: This is an observational pre/post-study of damage to buildings during the first month of the Israel Defence Force bombardment of Gaza from 7 October to 7 November 2023. Open-source polygons for the Gaza Strip were spatially joined with building damage assessments from satellite imagery analysis. Medical facilities were included in the analysis if they were cross-referenced by a minimum of two datasets. Welch's t-test was used to test for statistically significant differences in the proportions of damaged medical complexes and other buildings. RESULTS: A total of 167 292 unique buildings were identified, including 106 cross-referenced medical complexes. Approximately 9% of non-medical buildings and medical complexes alike sustained damage during the first month of the bombardment (p>0.7292). CONCLUSION: During the first month of the bombing campaign, evidence suggests medical complexes have not received special protection as required by IHL. This finding raises concerns about combatants' application of the principles of distinction, proportionality and precaution, suggesting the importance of further investigation.

RESUMEN

Despite having the highest prevalence of any sexually transmitted infection (STI) globally, there is a dearth of data describing Trichomonas vaginalis (TV) incidence and prevalence in the general population. The lack of basic epidemiological data is an obstacle to addressing the epidemic. Once considered a nuisance infection, the morbidities associated with TV have been increasingly recognised over the past decade, highlighting the importance of this pathogen as a public health problem. Recent developments in TV diagnostics and molecular biology have improved our understanding of TV epidemiology. Improved characterisation of the natural history of TV infection has allowed us to hypothesise possible explanations for observed variations in TV prevalence with age. Direct and indirect hormonal effects on the female genital tract provide a likely explanation for the greater burden of persistent TV infection among women compared with men. Further characterisation of the global epidemiology of TV could enhance our ability to respond to the TV epidemic.

RESUMEN

INTRODUCTION: The postpartum period can be challenging for women living with HIV. Understanding how the postpartum period impacts ART adherence and condomless sex could inform the development of comprehensive sexual and reproductive health and HIV services tailored to the needs of women living with HIV during this critical interval. METHODS: In a longitudinal cohort study of HIV-seropositive Kenyan women, late ART refills and self-reported condomless sex were compared between the woman's pregnancy and the postpartum period. Analyses were conducted using generalized estimating equations and adjusted for alcohol use, depressive symptoms, intimate partner violence (IPV), and having a recent regular partner. Effect modification was explored for selected variables. RESULTS AND DISCUSSION: 151 women contributed visits. Late ART refills occurred at 7% (32/439) of pregnancy visits compared to 18% (178/1016) during the postpartum period (adjusted relative risk [aRR] 2.44, 95% confidence interval [CI] 1.62-3.67). This association differed by women's education level. Women with ≥8 years of education had late ART refills more during the postpartum period than pregnancy (aRR 3.00, 95%CI 1.95-4.62). In contrast, in women with <8 years of education, late ART refills occurred similarly during pregnancy and the postpartum period (aRR 0.88, 95%CI 0.18-4.35). Women reported condomless sex at 10% (60/600) of pregnancy visits compared to 7% (72/1081) of postpartum visits (aRR 0.76, 95%CI 0.45-1.27). This association differed by whether women had experienced recent IPV. Women without recent IPV had a significant decline in condomless sex from pregnancy to postpartum (aRR 0.53, 95%CI 0.30-0.95) while women with recent IPV had no significant change in condomless sex from pregnancy to postpartum (aRR 1.76, 95%CI 0.87-3.55). CONCLUSION: Improved support for ART adherence during the postpartum period and addressing IPV to limit condomless sex could improve HIV treatment and prevention outcomes for HIV-seropositive women as well as their infants and sexual partners.

RESUMEN

INTRODUCTION: The identification of spatial-temporal clusters of forced migrant mortality is urgently needed to inform preventative policies and humanitarian response. As a first step towards understanding the geography of forced migrant mortality, this study investigates spatial-temporal patterns in death at a global scale. METHODS: We used information on the location and dates of forced migrant deaths reported in the International Organization for Migration's Missing Migrant Project from 2014 to 2018. Kulldorff's spatial-temporal and seasonal scans were used to detect spatial-temporal and temporal heterogeneity in mortality. RESULTS: A total of 16 314 deaths were reported during the study period. A preponderance of deaths occurred at sea each year (range 26%-54% across 5 years). Twelve spatial-temporal clusters of forced migrant mortality were detected by maximum likelihood testing. Annually, the period of August-October was associated with a 40-percentage-point increase in the risk of mortality, relative to other time periods. CONCLUSIONS: Death during forced migration occurs close to national borders and during periods of intense conflict. This evidence may inform the design of policies and targeting of interventions to prevent forced migration-related deaths.

RESUMEN

Crisis-affected populations and humanitarian aid providers are both becoming increasingly reliant on information and communications technology (ICTs) for finding and provisioning aid. This is exposing critical, unaddressed gaps in the legal and ethical frameworks that traditionally defined and governed the professional conduct of humanitarian action. The most acute of these gaps is a lack of clarity about what human rights people have regarding information in disaster, and the corresponding obligations incumbent upon governments and aid providers.  This need is lent urgency by emerging evidence demonstrating that the use of these technologies in crisis response may be, in some cases, causing harm to the very populations they intend to serve.  Preventing and mitigating these harms, while also working to responsibly ensure access to the benefits of information during crises, requires a rights-based framework to guide humanitarian operations. In this brief report, we provide a commentary that accompanies our report, the Signal Code: A Human Rights Approach to Information During Crisis, where we have identified five rights pertaining to the use of information and data during crisis which are grounded in current international human rights and customary law. It is our belief that the continued relevance of the humanitarian project, as it grows increasingly dependent on the use of data and ICTs, urgently requires a discussion of these rights and corresponding obligations.

RESUMEN

Despite a high prevalence of oncogenic human papilloma virus (HPV) infection and cervical cancer mortality, HPV vaccination is not currently available in Mali. Knowledge of HPV and cervical cancer in Mali, and thereby vaccine readiness, may be limited. Research staff visited homes in a radial pattern from a central location to recruit adolescent females and males aged 12-17 years and men and women aged ≥ 18 years (N = 51) in a peri-urban village of Bamako, Mali. Participants took part in structured interviews assessing knowledge, attitudes, and practices related to HPV, cervical cancer, and HPV vaccination. We found low levels of HPV and cervical cancer knowledge. While only 2.0% of respondents knew that HPV is a sexually transmitted infection (STI), 100% said they would be willing to receive HPV vaccination and would like the HPV vaccine to be available in Mali. Moreover, 74.5% said they would vaccinate their child(ren) against HPV. Men were found to have significantly greater autonomy in the decision to vaccinate themselves than women and adolescents (p = 0.005), a potential barrier to be addressed by immunization campaigns. HPV vaccination would be highly acceptable if the vaccine became widely available in Bamako, Mali. This study demonstrates the need for a significant investment in health education if truly informed consent is to be obtained for HPV vaccination. Potential HPV vaccination campaigns should provide more information about HPV and the vaccine. Barriers to vaccination, including the significantly lower ability of the majority of the target population to autonomously decide to get vaccinated, must also be addressed in future HPV vaccine campaigns.
