Enhancing HIV positivity yield in southern Mozambique: The effect of a Ministry of Health training module in targeted provider-initiated testing and counselling.

In Mozambique, targeted provider-initiated HIV testing and counselling (PITC) is recommended where universal PITC is not feasible, but its effectiveness depends on healthcare providers' training. This study aimed to evaluate the effect of a Ministry of Health training module in targeted PITC on the HIV positivity yield, and identify factors associated with a positive HIV test. We conducted a single-group pre-post study between November 2018 and November 2019 in the triage and emergency departments of four healthcare facilities in Manhiça District, a resource-constrained semi-rural area. It consisted of two two-month phases split by a one-week targeted PITC training module ("observation phases"). The HIV positivity yield of targeted PITC was estimated as the proportion of HIV-positive individuals among those recommended for HIV testing by the provider. Additionally, we extracted aggregated health information system data over the four months preceding and following the observation phases to compare yield in real-world conditions ("routine phases"). Logistic regression analysis from observation phase data was conducted to identify factors associated with a positive HIV test. Among the 7,102 participants in the pre- and post-training observation phases (58.5% and 41.5% respectively), 68% were women, and 96% were recruited at triage. In the routine phases with 33,261 individuals (45.8% pre, 54.2% post), 64% were women, and 84% were seen at triage. While HIV positivity yield between pre- and post-training observation phases was similar (10.9% (269/2470) and 11.1% (207/1865), respectively), we observed an increase in yield in the post-training routine phase for women in triage, rising from 4.8% (74/1553) to 7.3% (61/831) (Yield ratio = 1.54; 95%CI: 1.11-2.14). Age (25-49 years) (OR = 2.43; 95%CI: 1.37-4.33), working in industry/mining (OR = 4.94; 95%CI: 2.17-11.23), unawareness of partner's HIV status (OR = 2.50; 95%CI: 1.91-3.27), and visiting a healer (OR = 1.74; 95%CI: 1.03-2.93) were factors associated with a positive HIV test. Including these factors in the targeted PITC algorithm could have increased new HIV diagnoses by 2.6%. In conclusion, providing refresher training and adapting the current targeted PITC algorithm through further research can help reach undiagnosed PLHIV, treat all, and ultimately eliminate HIV, especially in resource-limited rural areas.

Field testing of user-friendly perennial malaria chemoprevention packaging in Benin, Côte d'Ivoire and Mozambique.

BACKGROUND: Perennial malaria chemoprevention (PMC) aims to protect children at risk from severe malaria by the administration of anti-malarial drugs to children of defined ages throughout the year. Sulfadoxine-pyrimethamine (SP) has been widely used for chemoprevention in Africa and a child-friendly dispersible tablet formulation has recently become available. METHODS: This qualitative non-interventional observational study was conducted in Benin, Côte d'Ivoire, and Mozambique between February and June 2022. Prototype blister packs, dispensing boxes and job aids designed to support dispersible SP deployment for PMC were evaluated using focus group discussions (FGD) and semi-structured in-depth individual interviews (IDI) with health authorities, health personnel, community health workers (CHWs) and caregivers. The aim was to evaluate knowledge and perceptions of malaria and chemoprevention, test understanding of the tools and identify gaps in understanding, satisfaction, user-friendliness and acceptability, and assess the potential role of CHWs in PMC implementation. Interviews were transcribed and imported to ATLAS.ti for encoding and categorization. Thematic content analysis used deductive and inductive coding with cross-referencing of findings between countries and participants to enrich data interpretation. Continuous comparison across the IDI and FGD permitted iterative, collaborative development of materials. RESULTS: Overall, 106 participants completed IDIs and 70 contributed to FGDs. Malaria was widely recognised as the most common disease affecting children, and PMC was viewed as a positive intervention to support child health. The role of CHWs was perceived differently by the target groups, with caregivers appreciating their trusted status in the community, whereas health authorities preferred clinic-based deployment of PMC by health professionals. Empirical testing of the prototype blister packs, dispensing boxes and job aids highlighted the context-specific expectations of respondents, such as familiar situations and equipment, and identified areas of confusion or low acceptance. A key finding was the need for a clear product identity reflecting malaria. CONCLUSION: Simple modifications profoundly affected the perception of PMC and influenced acceptability. Iterative quantitative investigation resulted in PMC-specific materials suited to the local context and socio-cultural norms of the target population with the aim of increasing access to chemoprevention in children most at risk of severe malaria.

Assessment of heavy metals and human health risk associated with the consumption of crops cultivated in industrial areas of Maputo, Mozambique.

This study aimed to evaluate heavy metals concentrations in soils and vegetables (cabbage, lettuce, and cassava) cultivated at Matola and Beluluane Industrial Parks, and to assess health risks linked to their consumption through estimated daily intake, hazard index (HI), and incremental lifetime cancer risk. Concentrations of Al, As, Co, Cd, Cr, Ni, Pb, and Zn were determined in the two sites. Soil concentrations of As at Beluluane site and As, Cd, and Cr at Matola site exceeded reference limits of the Food and Agriculture Organization/World Health Organization, showing heavy metal contamination. At Beluluane site, all studied vegetables presented As and Pb levels higher than reference limits, Cd concentrations were higher than the reference limit in cabbage, lettuce, and cassava leaves. At Matola site crops concentrations of As, Cd, Cr, and Pb exceeded the reference limits. Zinc exceeded the reference limit in all crops except in cabbage. HIs for vegetables from Beluluane exceeded 1.0 in cabbage (2.66), lettuce (2.27), and cassava leaves (2.37). Likewise, at Matola, HIs exceeded 1.0 in lettuce (1.67), cassava leaves (1.65), and root tubers (13). We found that vegetables cultivated in industrial parks present high carcinogenic risk due to heavy metal contamination, rendering them unsuitable for human consumption.

Sustained clinical benefit of malaria chemoprevention with sulfadoxine-pyrimethamine (SP) in pregnant women in a region with high SP resistance markers.

OBJECTIVE: The effectiveness of intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) is threatened by increasing SP-resistance in Africa. We assessed the level of SP-resistance markers, and the clinical and parasitological effectiveness of IPTp-SP in southern Mozambique. METHODS: P. falciparum infection, antimalarial antibodies and dhfr/dhps SP-resistance mutants were detected by quantitative polymerase chain reaction (qPCR), suspension array technology and targeted deep sequencing, respectively, among 4016 HIV-negative women in Maputo province (2016-2019). Univariate and multivariate regression models were used to assess the association between taking the recommended three or more IPTp-SP doses (IPTp3+) and parasitological and clinical outcomes. RESULTS: 84.3% (3385/4016) women received three or more IPTp-SP doses. The prevalence of quintuple mutants at first antenatal care (ANC) visit was 94.2%. IPTp3+ was associated with a higher clearance rate of qPCR-detected infections from first ANC visit to delivery (adjusted odds ratio [aOR]=5.9, 95% CI: 1.5-33.3; p = 0.012), lower seroprevalence at delivery of antibodies against the pregnancy-specific antigen VAR2CSADBL34 (aOR=0.72, 95% CI: 0.54-0.95; p = 0.022), and lower prevalence of low birth weight deliveries (aOR: 0.61, 95% CI: 0.41-0.90; p = 0.013). CONCLUSION: A sustained parasitological effect of IPTp-SP contributes to the clinical effectiveness of IPTp3+ in areas with high prevalence of SP-resistance markers.

Tobacco policy (in)coherence in Mozambique: an examination of national and subnational stakeholder perspectives.

Mozambique ranks fifth on the list of tobacco producing countries in Africa, while also being a Party to the WHO Framework Convention on Tobacco Control (FCTC). Tobacco farming is regarded by some governments as a strategic economic commodity for export and remains deeply entrenched within Mozambique's political and economic landscape. This study uses a qualitative description methodology to identify tensions, conflicts and alignment or misalignment in policy on tobacco across government sectors and levels in Mozambique. We conducted semi-structured qualitative interviews with 33 key informants from sectors across national and subnational levels including health, agriculture, economic and commercial sectors, as well as non-state actors from civil society organizations, the tobacco industry, farmers unions and associations and individual farmers. Incoherence was present across sectoral mandates, perspectives on industry's presence in the country and regions and between FCTC provisions and informant perceptions of tobacco production as a development strategy. Despite tobacco being viewed as an important economic commodity by many informants, there was also widespread dissatisfaction with tobacco from both farmers and some government officials. There were indications of an openness to shifting to a policy that emphasizes alternatives to tobacco growing. The findings also illustrate where points of convergence exist across sectors and where opportunities for aligning tobacco policy with the provisions of the FCTC can occur.

A probabilistic approach to compare the risk associated with heavy metals and bromine in honey from Dominican Republic, Mexico, Mozambique and Spain.

This study aims to analyse the risk to consumers given the presence of heavy metals and bromine in honey from different countries. A probabilistic approach was applied to assess carcinogenic risk. Concerning exposure, Al in Spain (3.3E-04 mg/kgBw/day), B in Dominican Republic and Mexico (2E-04 mg/kgBw/day in both cases) and Fe in Mexico and Mozambique had the highest values (5E-05 and 4.8E-05 mg/kgBw/day). In risk characterisation, the values were less than 1 for hazard index (HI), meaning that the consumption of honey represents a low level of concern for non-genotoxic effects. A combination of margin of exposure and probability of exceedance results that exposure to Pb pose no threat. The probability of suffering cancer for Br, Cd, Ni and Pb was lower than 1.0E-06 and, therefore, considered safe. However, the risk at the 95th percentile of Br in Dominican Republic was 1.18E-04 in adults and 2.45E-04 in children, exceeding 1.0E-04, and therefore, considered intolerable. Finally, the sensitivity analysis indicated that the most influential factor in the HI was the consumption in adults and the concentration of Ni in children, whereas for cancer risk, were the concentrations of Ni, Cd, Br and Pb, in both cases.

Cervical cancer in Mozambique: Clinical characteristics, treatment and survival of incident cases admitted to the Oncology Service of Maputo Central Hospital in 2016-2018.

In Mozambique, cervical cancer is the most frequent cancer in women. However, studies about cervical cancer treatment and prognosis are scarce. We describe the clinical characteristics, treatment and survival of patients with cervical cancer admitted to Maputo Central Hospital (MCH) in 2016 to 2018. Sociodemographic, clinical and cancer-related data were retrieved from clinical records of patients admitted to the Oncology Service of the MCH with an incident cervical cancer in 2016 to 2018 (n = 407). The Pathology Service database was used to obtain information regarding pathological diagnosis. Survival data was obtained through the MCH Cancer Registry and clinical records. Odds ratios for the association between patients' characteristics and the diagnosis of advanced stage cancer were computed using logistic regression. Survival analyses were performed using the Kaplan-Meier estimator. A total of 91.2% of the patients were diagnosed with advanced disease (stage IIB-IV) and squamous cell carcinoma was the predominant histological subtype. Most of the patients underwent chemotherapy (93.1%) but <7% were submitted to surgery, radiotherapy or brachytherapy. Those living with HIV had 3.4-fold higher odds of advanced disease. Overall survival was 72.7% (95% confidence interval [CI]: 67.9-77.0) at 1-year and 51.0% (95%CI: 45.3-56.3) at 2-years. Those with early stage (IA-IIA) and asymptomatic at diagnosis had a significantly higher 2-year overall survival. In Mozambique, cervical cancer is diagnosed mostly in advanced stages, resulting in poor prognosis. This highlights the importance of HPV vaccination and screening, to decrease the burden of cervical cancer in this context.

Tobacco consumption in Mozambique in 2005 and 2015.

INTRODUCTION: The burden related to smoking exposure is growing in many low-income settings. We aimed to quantify the use of smoked and smokeless tobacco in Mozambique in 2014/2015, and to compare the estimates with those obtained in 2005. METHODS: A cross sectional study was conducted in 2014/2015 on a representative sample of the Mozambican population aged 15 to 64 years, following the World Health Organization Stepwise Approach to Chronic Disease Risk Factor Surveillance (STEPS). Prevalence estimates with 95% confidence intervals were computed for different categories of tobacco consumption. The age-standardised prevalence in the age-group 25-64 years was compared with results from a STEPS survey conducted in 2005. RESULTS: Between 2005 and 2014/2015, the prevalence of daily smoking decreased from 9.1% to 3.4% (p < 0.05) in women and from 33.6% to 27.3% (p < 0.05) in men. There was a significant decrease in the daily consumption of hand-rolled cigarettes among women (from 3.1% to 1.4%, p < 0.05). Among men, there was a decrease in the prevalence of daily consumption of smokeless tobacco (from 3.5% to 1.0%, p < 0.05). In 2014/2015, both manufactured and hand-rolled cigarette consumption were more prevalent among men, while the use of smokeless tobacco was more common among women; the consumption of both hand-rolled cigarettes and smokeless tobacco were more prevalent in rural settings. DISCUSSION AND CONCLUSIONS: In Mozambique, there was a decrease in the prevalence of daily smokers in both genders and of daily consumption of smokeless tobacco among men between 2005 and 2014/2015. Efforts are needed to maintain the positive trends.

Knowledge about Cervical Cancer Prevention and Screening in Women with Cervical Cancer Attending Gynecological Services in Southern Mozambique.

BACKGROUND: Mozambique has high rates of cervical cancer and cancer-related deaths among women. A high rate of refusal and low acceptance of treatment is observed among cervical cancer patients. The extent of their knowledge of the disease is unknown. OBJECTIVES: To assess knowledge about this disease (prevention, risk factors, and the possibilities of early diagnosis) in women with cervical cancer attended in gynecological services in Gaza province, Mozambique. MATERIALS AND METHODS: This cross-sectional study took place in the city of Xai-Xai at the Provincial Hospital of Xai-Xai (HPXX) in the southern province of Gaza (Mozambique). Non-probability convenience sampling was used. Eligible patients (women) aged 35-50 years, diagnosed with cervical cancer and followed at the HPXX in the second quarter of 2021 (n = 60), took part in the survey during their scheduled consultations. Descriptive statistics were calculated using SPSS statistical software (version 16). RESULTS: The study included 60 women, 39 (65%) HIV positive. More than half (55.0%) believed that having a single sexual partner was an effective form of prevention; 50.0% reported that excessive alcohol consumption and having many sexual partners could cause the disease, and 46.7% affirmed that having many children increased the risk. Thirty-eight (63.3%) women reported that early diagnosis of cervical cancer was important for receiving prompt treatment, and 54 (90.0%) said regular visits to the gynecologist were important for an early diagnosis. Thirty-five (58.3%) mentioned acetic acid screening as a diagnostic test. CONCLUSIONS: There are significant gaps in awareness of cervical cancer among high-risk groups.

Evaluation of the Performance of a 3D-Printed Smartphone-Based Retinal Imaging Device as a Screening Tool for Retinal Pathology in Mozambique.

Low-income countries carry approximately 90% of the global burden of visual impairment, and up to 80% of this could be prevented or cured. However, there are only a few studies on the prevalence of retinal disease in these countries. Easier access to retinal information would allow differential diagnosis and promote strategies to improve eye health, which are currently scarce. This pilot study aims to evaluate the functionality and usability of a tele-retinography system for the detection of retinal pathology, based on a low-cost portable retinal scanner, manufactured with 3D printing and controlled by a mobile phone with an application designed ad hoc. The study was conducted at the Manhiça Rural Hospital in Mozambique. General practitioners, with no specific knowledge of ophthalmology or previous use of retinography, performed digital retinographies on 104 hospitalized patients. The retinographies were acquired in video format, uploaded to a web platform, and reviewed centrally by two ophthalmologists, analyzing the image quality and the presence of retinal lesions. In our sample there was a high proportion of exudates and hemorrhages-8% and 4%, respectively. In addition, the presence of lesions was studied in patients with known underlying risk factors for retinal disease, such as HIV, diabetes, and/or hypertension. Our tele-retinography system based on a smartphone coupled with a simple and low-cost 3D printed device is easy to use by healthcare personnel without specialized ophthalmological knowledge and could be applied for the screening and initial diagnosis of retinal pathology.

Expanding Cervical Cancer Screening in Mozambique: Challenges Associated With Diagnosing and Treating Cervical Cancer.

PURPOSE: Mozambique has one of the highest burdens of cervical cancer globally. Treatment options are few as most women present with advanced disease, and there are limited trained health professionals and health care resources. The objective of this study was to describe the outcomes of women diagnosed with invasive cancer as part of the Mozambican women undergoing cervical cancer screening with human papillomavirus (HPV) testing in conjunction with family planning services (MULHER) study. MATERIALS AND METHODS: Women age 30-49 years were prospectively enrolled in the MULHER study and offered screening with primary HPV testing followed by treatment of screen-positive women with thermal ablation or excision as appropriate. Women with cervical examination findings suspicious for cancer were referred to one of the three gynecologic oncologists in the country. RESULTS: Between January 2020 and January 2023, 9,014 women underwent cervical cancer screening and 30 women were diagnosed with cervical cancer. In this cohort, four patients (13.3%) had early-stage disease, 18 (60.0%) had locally advanced disease, one (3.3%) had distant metastatic disease, and seven (23.3%) did not have staging information available. Five patients (16.6%) died without receiving oncologic treatment, and seven patients (23.3%) are still awaiting treatment. Of the remaining 18 patients, three (17.6%) underwent surgery and four (23.5%) received radiotherapy. Eleven (36.7%) patients received only chemotherapy. CONCLUSION: As cervical screening programs are implemented in low-resource settings, there will likely be an increase in the number of women diagnosed with invasive cervical cancer. Our results in Mozambique demonstrate the need to increase access to advanced surgery, radiation, and palliative care services.

The Mulher Study: cervical cancer screening with primary HPV testing in Mozambique.

OBJECTIVE: To evaluate cervical cancer screening with primary human papillomavirus (HPV) testing in Mozambique, a country with one of the highest burdens of cervical cancer globally. METHODS: Women aged 30-49 years were prospectively enrolled and offered primary HPV testing using either self-collected or provider-collected specimens. Patients who tested positive for HPV underwent visual assessment for treatment using visual inspection with acetic acid to determine eligibility for thermal ablation. If ineligible, they were referred for excision with a loop electrosurgical excision procedure, for cold knife conization, or for cervical biopsy if malignancy was suspected. RESULTS: Between January 2020 and January 2023, 9014 patients underwent cervical cancer screening. Median age was 37 years (range 30-49) and 4122 women (45.7%) were patients living with HIV. Most (n=8792, 97.5%) chose self-collection. The HPV positivity rate was 31.1% overall and 39.5% among patients living with HIV. Of the 2805 HPV-positive patients, 2588 (92.3%) returned for all steps of their diagnostic work-up and treatment, including ablation (n=2383, 92.1%), loop electrosurgical excision procedure (n=169, 6.5%), and cold knife conization (n=5, 0.2%). Thirty-one patients (1.2%) were diagnosed with cancer and referred to gynecologic oncology. CONCLUSION: It is feasible to perform cervical cancer screening with primary HPV testing and follow-up in low-resource settings. Participants preferred self-collection, and the majority of screen-positive patients completed all steps of their diagnostic work-up and treatment. Our findings provide important information for further implementation and scale-up of cervical cancer screening and treatment services as part of the WHO global strategy for the elimination of cervical cancer.

The Infomóvel-An information system for managing HIV/AIDS patients in rural areas of Mozambique.

BACKGROUND: Mobile health is gradually revolutionizing the way medical care is delivered worldwide. In Mozambique, a country with a high human immunodeficiency virus prevalence, where antiretroviral treatment coverage is 77% accompanied by a 67% of retention rate, the use of mobile health technology may boost the antiretroviral treatment, by delivering care beyond health facilities and reaching underrepresented groups. Leveraging new technologies is crucial to reach the 95-95-95 United Nations target by 2030. The design, development, implementation, and evaluation of a mobile health platform called Infomóvel were covered in this article. Its intended use involves collaboration with community health workers and aims to increase human immunodeficiency virus patient access, adherence, and retention to care. METHODS: Using the Design Science Research Methodology, Infomóvel was created, as well as this publication. The explanation of various actions includes everything from problem description to observational study and goal-following for a solution, which results in the design and development of a platform proposal. Before the utility assessment of Infomóvel was conducted to make adjustments, a demonstration phase was conducted in one region of Mozambique. RESULTS: The initial subjects of the Infomóvel flowchart and physical process design were patients receiving antiretroviral medication who were enrolled in the patients tracking system and who had consented to home visits. The case manager examines the file before importing it into the Infomóvel database stored on a cloud server using the website www.commcarehq.org . The case manager application synchronises with the Infomóvel server database, enabling the import of latest data and access to the lists of new patients and community health workers. The community health worker uses his phone to access his application, which allows him to record the geographic coordinates and sort the list of patients by priority and type of visit. CONCLUSION: Results from Infomóvel add to the growing body of data showing that mobile health techniques are beneficial for managing stable individuals with chronic conditions in Mozambique. These approaches can be scaled up and better utilised. However, additional studies should be conducted to quantify the resources needed to implement on a larger scale.

Element Concentrations in Muscle and Liver Tissue of Two Eel Species from the Incomati River, Mozambique.

Many rural communities in Mozambique get their income from fisheries, as well as consume fish as an inexpensive source of protein. In Mozambique, fish consumption from small-scale fisheries dependent families can range between 60 and 150 kg/person/year. Anguillid eels have important social value to vulnerable local communities in the Incomati Basin. Anguillid eels in the lower Incomati Basin are targeted for consumption, as well as cultural rituals by traditional healers. The aim of the present study was to determine trace element concentrations in environmental matrices, bioaccumulation patterns in muscle and liver tissue of two Anguilla species (Anguilla mossambica and Anguilla marmorata), as well as the chronic health risk these elements pose to regular consumers in the lower Incomati River. Bioaccumulation of elements from the water had a higher effect on both muscle and liver tissues, where only the bioaccumulation of Pb in the sediments played a major role. From the human health risk assessment, Hg pose non-carcinogenic risk, whereas As, Cr, and Ni pose carcinogenic risks.

Pharmacogenetic analysis of inter-ethnic variability in the uptake transporter SLCO1B1 gene in Colombian, Mozambican, and Portuguese populations.

BACKGROUND: Statin-induced myopathy is reported to be associated with the solute carrier organic anion transporter family member 1B1 gene single nucleotide polymorphism, c.521 T > C. There is no epidemiologic data on this gene polymorphism in several countries. Therefore, this study aimed at assessing the genotype and allele frequencies of the gene variant in three countries. METHODS: This study involved healthy individuals from Colombia, Mozambique, and Portugal. Genomic DNA was isolated from blood samples using the Qiamp DNA Extraction Kit (Qiagen). The isolated DNA was genotyped using novel Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. Microstat and GraphPad QuickCal software were used for the Chi-square test and the evaluation of Hardy-Weinberg equilibrium respectively. RESULTS: A total of 181 individuals' blood samples were analyzed. Overall, the TT (74.0%) genotype was the highest and the CC (7.8%) was the lowest. Country wise genotypic frequencies were Colombia 47(70.2%) TT, 12(17.9%) TC and 8(11.9%) CC; Mozambique 47(88.7%) TT, 5(9.4%) TC, and 1(1.9%) CC; and Portugal 40(65.6%) TT, 16(26.2%) TC, and 5(8.2%) CC. The reference (T) allele was highest among Mozambicans (93.4%) compared to Colombians (79.1%) and Portuguese (78.7%). Mozambicans showed statistically significant genotypic and allelic frequency differences compared to Colombians (p < 0.01) and Portuguese (p < 0.01). CONCLUSIONS: Overall and country-wise, CC genotype was less frequent and it is relatively high for Colombians and Portuguese populations. This finding may imply statins risk-benefit variability associated with CC genotype among these populations that needs further understanding.

Screening approaches for cervical cancer in Mozambique in HIV positive and negative women.

OBJECTIVE: Cervical cancer (CC) is a global health issue, in Mozambique, 5300 new cases and 3800 deaths are reported each year. The WHO recommends the introduction of HPV molecular testing for CC screening, but Mozambique uses an approach based on visual inspection with acetic acid (VIA). This study aims to evaluate the feasibility of high-risk HPV (hrHPV) testing compared to actual approaches in Mozambique. METHODS: An observational study was carried out in the DREAM center in Zimpeto, Mozambique. Women aged 30-55 were included. HPV testing was performed with the Cobas HPV test. They were then screened with the current national recommendations based on VIA. Cryotherapy was performed on-site or referred for colposcopy if necessary. RESULTS: In the period, 1207 women were enrolled, 47.8% HIV+; 124 (10.3%) VIA+, and HPV DNA test was positive in 325 (26.9%) women. HPV positivity rates were higher in HIV-infected women. In the sample, 52.8% of the 124 VIA+ women were HPV uninfected and underwent unnecessary cryotherapy or colposcopy. Meanwhile, 24.7% of the 1083 VIA- women were actually HPV infected. In comparison, a screen, triage and treat approach based on hrHPV testing would only test and treat the 325 HPV-infected women. CONCLUSION: The study found high rates of hrHPV infection, particularly in HIV-positive women, with many concurrent or multiple infections. The current screening method misses important hrHPV infections and results in many unnecessary treatments. These results support the use of HPV molecular testing as the initial screening test for CC.

Verbal and Social Autopsy of Adult Deaths and Adult Care-Seeking Pattern in Mozambique, 2019-2020.

In sub-Saharan Africa, recent data about causes of adult death and care-seeking during illnesses are limited. This analysis examines adult deaths using verbal and social autopsy data from a nationally and provincially representative sample registration system in Mozambique. Causes of death among those 18 years and older were assigned using the InSilicoVA algorithm, and underlying social causes were examined using the pathway to survival model. Care-seeking was analyzed in different groups to determine if care was sought from formal providers (doctor, nurse/midwife, and trained community health worker) or other providers (traditional provider, family member, and pharmacist), using χ2 tests and multinomial regression models. Among the 4,040 adult deaths reported during 2019-2020, the major causes were HIV (17%), cancer (13%), injury (10%), cardiovascular diseases (9%), pneumonia (7%), tuberculosis (5%), and maternal causes (3%). Formal care-seeking was more likely among adults who had primary or higher level education (relative risk ratio [RRR]: 1.6, P < 0.001; RRR: 1.7, P < 0.01), were married (RRR: 1.3, P < 0.01), and had highest household wealth (RRR: 3.1, P < 0.001). Formal care-seeking was less likely among adults who were male (RRR: 0.7, P < 0.001), had social capital (RRR: 0.7, P < 0.05), or resided in the southern region (RRR: 0.4, P < 0.001). Information about adult causes of death is useful for formulating policy and for developing, monitoring, and evaluating programs to improve adult health in Mozambique. Care-seeking-related information helps identify barriers for seeking care from formal health providers while emphasizing the need for generating local resources and strengthening outreach health systems service delivery.

Countrywide Mortality Surveillance for Action in Mozambique: Results from a National Sample-Based Vital Statistics System for Mortality and Cause of Death.

Sub-Saharan Africa lacks timely, reliable, and accurate national data on mortality and causes of death (CODs). In 2018 Mozambique launched a sample registration system (Countrywide Mortality Surveillance for Action [COMSA]-Mozambique), which collects continuous birth, death, and COD data from 700 randomly selected clusters, a nationally representative population of 828,663 persons. Verbal and social autopsy interviews are conducted for COD determination. We analyzed data collected in 2019-2020 to report mortality rates and cause-specific fractions. Cause-specific results were generated using computer-coded verbal autopsy (CCVA) algorithms for deaths among those age 5 years and older. For under-five deaths, the accuracy of CCVA results was increased through calibration with data from minimally invasive tissue sampling. Neonatal and under-five mortality rates were, respectively, 23 (95% CI: 18-28) and 80 (95% CI: 69-91) deaths per 1,000 live births. Mortality rates per 1,000 were 18 (95% CI: 14-21) among age 5-14 years, 26 (95% CI: 20-31) among age 15-24 years, 258 (95% CI: 230-287) among age 25-59 years, and 531 (95% CI: 490-572) among age 60+ years. Urban areas had lower mortality rates than rural areas among children under 15 but not among adults. Deaths due to infections were substantial across all ages. Other predominant causes by age group were prematurity and intrapartum-related events among neonates; diarrhea, malaria, and lower respiratory infections among children 1-59 months; injury, malaria, and diarrhea among children 5-14 years; HIV, injury, and cancer among those age 15-59 years; and cancer and cardiovascular disease at age 60+ years. The COMSA-Mozambique platform offers a rich and unique system for mortality and COD determination and monitoring and an opportunity to build a comprehensive surveillance system.

Hepatitis B virus genotypes and drug resistance mutations circulating in blood donors in Beira, Mozambique.

Hepatitis B virus (HBV) infects nearly 300 million people and is the leading cause of hepatitis and hepatocellular carcinoma worldwide. Despite the high burden of HBV in sub-Saharan Africa, countries such as Mozambique have limited data available on circulating HBV genotypes and the presence of drug resistance mutations. Blood donors from Beira, Mozambique were tested for HBV surface antigen (HBsAg) and HBV DNA at the Instituto Nacional de Saúde in Maputo, Mozambique. Regardless of HBsAg status, donors with detectable HBV DNA were evaluated for HBV genotype. PCR was performed with primers amplifying a 2.1-2.2 kilobase fragment of the HBV genome. PCR products were submitted for next generation sequencing (NGS), and consensus sequences were evaluated for HBV genotype, recombination, and the presence or absence of drug resistance mutations. Of the 1281 blood donors tested, 74 had quantifiable HBV DNA. The polymerase gene could be amplified from 45 of 58 (77.6%) individuals with chronic HBV infection and 12 of 16 (75%) with occult HBV infection. Among these 57, 51 (89.5%) sequences belonged to HBV genotype A1, while 6 (10.5%) were HBV genotype E. All genotype E sequences were E/A recombinants, and clustered separately from other genotype E references. Genotype A samples had a median viral load of 637 IU/mL, while genotype E samples had a median viral load of 476,084 IU/mL. No drug resistance mutations were observed in the consensus sequences. The current study demonstrates the genotypic diversity of HBV in blood donors in Mozambique, but the absence of dominant (consensus) drug resistance mutations. Studies in other at-risk populations are essential for understanding the epidemiology, risk of liver disease, and likelihood of treatment resistance in resource-limited settings.

Assessment of cataract surgery outcomes in Nampula (Mozambique): visual acuity, visual function and quality of life.

BACKGROUND: Despite advances in surgical techniques, cataract remains the leading cause of preventable blindness, and massive surgeries have been adopted as a strategy to change this situation. Monitoring the results of cataract surgeries has become imperative to ensure their quality. Therefore, this study aims to assess the cataract surgery outcomes performed at the Central Hospital of Nampula Mozambique. METHODS: This is a prospective and longitudinal study in which translation, cultural adaptation and validation of the visual function (VF) and quality of life (QoL) questionnaire were performed. The appearance, content, construct, criterion, internal consistency and responsiveness were validated using the most common methods and indicators. Visual acuity (VA), VF and QoL were evaluated on 447 patients before and after surgery by t-test and effect sizes. RESULTS: VF and QoL questionnaires showed one-dimension, good values of TLI (0.973, 0.951) and SRMR (0.057, 0.054), and for each item, weights > 0.7, H2 > 0.5, ranges > 5.8 and the RMSEA < 0.08. Correlations for criterion validity were high and for responsiveness were high for QoL and moderate for VF one and the ordinal Cronbach's alpha coefficients were greater than 0.97. Difference between VA, VF and QoL before and after surgery was statistically significant (p < 0.001). After surgery, 74.3% of patients had good, 23.5% had borderline and 2.2% had poor VA. CONCLUSIONS: The cataract surgery outcomes are outside the WHO recommendations regarding VA, but they have had a great impact on improving VF and QoL. The questionnaires showed excellent psychometric properties and should be used in daily clinical practice to evaluate the results of cataract surgeries.
