RESUMO
BACKGROUND: Togo's National Malaria Control Programme has initiated an active home-based malaria management model for all age groups in rural areas of Bassar Health District. This report describes the model, reports its main results, and determines the factors associated with positive rapid diagnostic test results. METHODS: From 2014 to 2017, in three peripheral care units of Bassar Health District (Binaparba, Nangbani, and Baghan), community health workers visited residents' homes weekly to identify patients with malaria symptoms, perform rapid diagnostic tests in symptomatic patients, and give medication to positive cases. Univariate and multivariate logistic regression models were used to determine the factors associated with positive tests. RESULTS: The study covered 11,337 people (817 in 2014, 1804 in 2015, 2638 in 2016, and 6078 in 2017). The overall mean age was 18 years (95% CI 5-29; min-max: 0-112 years). The median age was 10 years (SD: 16.9). The proportions of people tested positive were 75.3% in Binaparba, 77.4% in Nangbani, and 56.6% in Baghan. The 5-10 age group was the most affected category (24.2% positive tests). Positive tests were more frequent during the rainy than during the dry season (62 vs. 38%) and the probability of positive test was 1.76 times higher during the rainy than during the dry season (adjusted OR = 1.74; 95% CI 1.60-1.90). A fever (37.5 °C or higher) increased significantly the probability of positive test (adjusted OR = 2.19; 95% CI 1.89-2.54). The risk of positive test was 1.89 times higher in passive than in active malaria detection (adjusted OR = 1.89; 95% CI 1.73-2.0). CONCLUSIONS: This novel experimental community and home-based malaria management in Togo suggested that active detection of malaria cases is feasible within 24 h, which allows rapid treatments before progression to often-fatal complications. This PECADOM + program will help Togo's National Malaria Control Programme reduce malaria morbidity and mortality in remote and hard-to-reach communities.

BACKGROUND: Artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) are the currently recommended first- and second-line therapies for uncomplicated Plasmodium falciparum infections in Togo. This study assessed the efficacy of these combinations, the proportion of Day3-positive patients (D3 +), the proportion of molecular markers associated with P. falciparum resistance to anti-malarial drugs, and the variable performance of HRP2-based malaria rapid diagnostic tests (RDTs). METHODS: A single arm prospective study evaluating the efficacy of AL and DP was conducted at two sites (Kouvé and Anié) from September 2021 to January 2022. Eligible children were enrolled, randomly assigned to treatment at each site and followed up for 42 days after treatment initiation. The primary endpoint was polymerase chain reaction (PCR) adjusted adequate clinical and parasitological response (ACPR). At day 0, samples were analysed for mutations in the Pfkelch13, Pfcrt, Pfmdr-1, dhfr, dhps, and deletions in the hrp2/hrp3 genes. RESULTS: A total of 179 and 178 children were included in the AL and DP groups, respectively. After PCR correction, cure rates of patients treated with AL were 97.5% (91.4-99.7) at day 28 in Kouvé and 98.6% (92.4-100) in Anié, whereas 96.4% (CI 95%: 89.1-98.8) and 97.3% (CI 95%: 89.5-99.3) were observed at day 42 in Kouvé and Anié, respectively. The cure rates of patients treated with DP at day 42 were 98.9% (CI 95%: 92.1-99.8) in Kouvé and 100% in Anié. The proportion of patients with parasites on day 3 (D3 +) was 8.5% in AL and 2.6% in DP groups in Anié and 4.3% in AL and 2.1% DP groups in Kouvé. Of the 357 day 0 samples, 99.2% carried the Pfkelch13 wild-type allele. Two isolates carried nonsynonymous mutations not known to be associated with artemisinin partial resistance (ART-R) (A578S and A557S). Most samples carried the Pfcrt wild-type allele (97.2%). The most common Pfmdr-1 allele was the single mutant 184F (75.6%). Among dhfr/dhps mutations, the quintuple mutant haplotype N51I/C59R/S108N + 437G/540E, which is responsible for SP treatment failure in adults and children, was not detected. Single deletions in hrp2 and hrp3 genes were detected in 1/357 (0.3%) and 1/357 (0.3%), respectively. Dual hrp2/hrp3 deletions, which could affect the performances of HRP2-based RDTs, were not observed. CONCLUSION: The results of this study confirm that the AL and DP treatments are highly effective. The absence of the validated Pfkelch13 mutants in the study areas suggests the absence of ART -R, although a significant proportion of D3 + cases were found. The absence of dhfr/dhps quintuple or sextuple mutants (quintuple + 581G) supports the continued use of SP for IPTp during pregnancy and in combination with amodiaquine for seasonal malaria chemoprevention.

OBJECTIVE: Non-traumatic lower limb amputation (NT-LLA) has consequences at individual and public health levels. Population based studies in sub-Saharan Africa are scarce and often related to single centre series. This study aimed to estimate the incidence of NT-LLA (minor and major) and to describe epidemiological, clinical, and prognostic aspects in Togo. METHODS: This was a population based observational study conducted among all patients who underwent NT-LLA. Traumatic amputations were excluded. Sociodemographic, clinical, and work up data were collected from clinical files in any Togolese health centre from 1 January 2016 to 31 December 2021. Incidence rates were adjusted for age. RESULTS: Over the six year period, 352 patients (59% males) underwent NT-LLA (mean ± standard deviation age 60 ± 15.7 years). The average age adjusted incidence rate of NT-LLA was 8.5 per million/year (95% confidence interval [CI] 7.6 - 9.4). Men were 1.7 times more likely to undergo a NT-LLA than women. The relative risk of NT-LLA was 48 times higher in patients with diabetes than in patients without diabetes. Around 61.0% of the NT-LLAs occurred within the 50 - 74 age group and 54.3% had diabetes mellitus. Among amputees, 54.5% had a diagnosis of peripheral artery disease (PAD) and 52.8% had diabetic ulcers, with co-existence of several factors. Less than 5% of participants had a history of smoking tobacco. Average length of hospital stay was 12 days. The in hospital mortality rate was 8.8% (9.0% for major, 6.7% for minor amputations). Only 18.2% had duplex ultrasound performed and 1.7% angiography prior to amputation. No patient underwent vascular intervention prior to amputation. CONCLUSION: This is the first study to report nationwide and contemporary epidemiological data on NT-LLAs in West Africa, highlighting several specificities. Large scale interventions are needed to ameliorate the care of diabetes and PAD and improve facilities for optimal management of patients at risk of amputation in Africa.

BACKGROUND: Leprosy, or Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. Togo achieved the target of eliminating leprosy as a public health problem in 2000 (less than 1 case/10 000 population). However, new cases of leprosy are still being reported. The aim of this study was to describe and map trends of leprosy cases notified in Togo from 2010 to 2022. METHODS: This was a descriptive cross-sectional study covering a thirteen-year period from January 1, 2010, to December 31, 2022. The data of the study were leprosy surveillance system's data collected monthly between 2010 and 2022. The estimated number of leprosy cases and the incidence rate of leprosy cases were reported for the whole population by region, by district, by calendar year (2010-2022) and by target sub-population (children under 15, women and people with disabilities). Observed case incidence rates were mapped by health district and by year. RESULTS: From January 1, 2010, to December 31, 2022, 1031 new cases of leprosy were diagnosed in Togo. The median age of subjects was 46 years (interquartile range: 33-60), with extremes from 4 to 96 years. Half the subjects were women (50.7%). Variations in the leprosy incidence rate by year show an increase between 2010 and 2022, from 0.7 cases /100,000 population to 1.1 /100,000 population respectively. From 2010 to 2022, the proportion of cases in children remained low, between 0 and 9%. The proportion of women fluctuated between 39.7% and 67.2% between 2010 and 2017, then stabilized at an average of 50% between 2018 and 2022. The proportion of multi-bacillary leprosy cases increased quasi-linearly between 2010 and 2022, from 70 to 96.6%. Mapping of leprosy cases showed that leprosy was notified in all Togo health districts during the study period, apart from the Lacs district, which reported no leprosy cases. CONCLUSION: Togo has achieved the elimination of leprosy as a public health problem. However, the increase in the number of new leprosy cases and the proportion of leprosy cases in children indicate that transmission of the disease is continuing and that supplementary measures are needed.

BACKGROUND: In 2015, Togo introduced the "test-and-treat" strategy for the prevention of mother-to-child transmission (PMTCT) of HIV. Pediatric HIV infection remains a public health problem in Togo, with a mother-to-child transmission (MTCT) rate of 3.6% in 2020. This study aimed to estimate cases of HIV seroconversion during pregnancy and to identify pregnant women at high risk of transmitting HIV to their children in Lomé, Togo. METHODS: A descriptive cross-sectional study was carried out from 18 March to 22 May 2022 among women who had given birth in five maternity units providing PMTCT services in Lomé. Umbilical cord blood samples were taken from the maternal side by midwives after delivery. HIV serology was performed in the laboratory using the Alere™ HIV Combo SET and First Response HIV 1-2. Card Test version 2.0. A sample was considered positive if both tests were positive. The HIV-1 viral load in HIV-1-positive samples was measured using Cobas/Roche 4800 equipment. Information on the women was extracted from maternal antenatal records and antenatal consultation registers. RESULTS: A total of 3148 umbilical cord blood samples (median maternal age: 28 years (interquartile range [24-32]) were collected. Among them, 99.3% (3145/3148) had presented for at least one antenatal clinic visit before giving birth, and 78.7% (2456/3122) had presented for at least four visits. One hundred and twenty-one (121) cord samples were HIV-1 positive, representing a seroprevalence of 3.8% (95% CI = [3.2-4.6]). Among them, 67.8% (82/121) were known HIV-positive before the current pregnancy, 29.7 (36/121) were diagnosed as HIV-positive at the antenatal visits and 2.5% (3/121) were diagnosed as HIV-positive in the delivery room. Of the HIV-positive women, 85.9% (104/121) were on ARV treatment before delivery. The viral load was < 1000 copies/ml in 97.5% (118/121) cases. CONCLUSION: This study explored the virologic and epidemiological aspects of HIV among pregnant women in Togo. The results show significant viral suppression at delivery in women ART. Surveillance based on umbilical cord blood specimen screening is an interesting approach for monitoring the effectiveness of PMTCT programmes.

INTRODUCTION: Access to data concerning mental health, particularly alcohol use disorders (AUD), in sub-Saharan Africa is very limited. This study aimed to estimate AUD prevalence and identify the associated factors in Togo and Benin. METHODS: A cross-sectional study was conducted between April and May 2022, targeting individuals aged 18 years and above in the Yoto commune of Togo and the Lalo commune of Benin. Subjects were recruited using a multi-stage random sampling technique. AUD diagnoses were made using the MINI adapted to DSM-5 criteria. Our study collected sociodemographic information, data on psychiatric comorbidities, stigmatization, and assessed cravings, using a series of scales. The association between AUD and various factors was analyzed using multivariable logistic regression. RESULTS: In Togo, 55 of the 445 people investigated had AUD (12.4%; [95% CI: 9.5-15.7%]). Among them, 39 (70.9%) had severe AUD and the main associated comorbidities were suicidal risk (36.4%), and major depressive disorder (16.4%). Associated factors with AUD were male gender (aOR: 11.3; [95% CI: 4.8-26.7]), a higher Hamilton Depression Rating Scale (HDRS) score (aOR: 1.2; [95% CI: 1.1-1.3]) and a lower Stigma score measured by the Explanatory Model Interview Catalogue (EMIC) (aOR: 0.9; [95% CI: 0.8-0.9). The stigma scores reflect perceived societal stigma towards individuals with AUD. In Benin, 38 of the 435 people investigated had AUD (8.7%; [95% CI: 6.4-11.7]), and the main associated comorbidities were suicidal risk (18.4%), tobacco use disorder (13.2%) and major depressive episode (16.4%). Associated factors with AUD were male gender (aOR: 6.4; [95% CI: 2.4-17.0]), major depressive disorder (aOR: 21.0; [95% CI: 1.5-289.8]), suicidal risk (aOR: 3.7; [95% CI: 1.2-11.3]), a lower Frontal Assessment Battery (FAB) score (aOR:0.8; [95% CI: 0.8-0.9]) and a lower perceived stigma score (by EMIC )(aOR: 0.9; [95% CI: 0.8-0.9]). CONCLUSION: In these communes of Togo and Benin, AUD prevalence is notably high. A deeper understanding of the disease and its local determinants, paired with effective prevention campaigns, could mitigate its impact on both countries.

BACKGROUND: In Togo, few data are available on viral hepatitis in street adolescents, a vulnerable population due to their lifestyle. The aim of this study was to describe the lifestyle of street adolescents (sexual practices and drug use), to estimate the prevalence of hepatitis B and C viruses, and to describe their HBV immunization profile in Togo. METHODS: A cross-sectional study was conducted in Lomé (Togo) in July 2021. Street adolescents aged between 13 and 19 years were included. A questionnaire was used to document lifestyle. ELISA tests were performed for Hepatitis B surface antigen (HBsAg), Hepatitis B core and surface antibodies (anti-HBc, anti-HBs), and antibodies against hepatitis C virus (anti-HCV). RESULTS: A total of 299 adolescents (5.4% female) with a median age of 15 years (IQR: 14-17) were included. Of these, 70.6% (211/299) were sexually active and 70.6% (149/211) had not used a condom during their last sexual intercourse. Drug use was reported by 42.1% of the adolescents. The most used substances were cannabis (39.0%), cocaine (36.6%), glue solvents (19.5%), and tramadol (11.4%). However, cocaine use may have been overestimated due to information bias. Current HBV infection (HBsAg+) was detected in 3.7% (95%CI: 1.9-6.5) of the adolescents. Isolated anti-HBc + was present in 5.3%. All three HBV markers (HBsAg, anti-HBs, and anti-HBc) were negative in 71.6% of adolescents. Anti-HCV was detected in 4.7% of adolescents. CONCLUSION: Nearly one in 10 street adolescents has markers for HBV contact/current infection, and approximately 72% of street adolescents may still be infected with HBV, as they have no HBV markers. HCV is also circulating in this population. Given the reported high-risk sexual practices and high levels of drug use, there is an urgent need to develop integrated strategies to prevent infections, including HBV, and drug dependence in this population.

OBJECTIVES: The study aims to gain a better understanding of the needs and health behaviours of young women at the University of Lomé (Togo) with regard to gynaecological care. STUDY DESIGN: The data comes from a self-administered online survey. METHODS: A logistic regression was applied to model the likelihood of non-use of gynaecological care. RESULTS: Among the 281 women who completed the survey, 75% declared they had not consulted a gynaecologist or healthcare professional for a question related to intimacy or contraception in the last 12 months, mainly because of the financial barrier (65%). But needs do exist as 73% of women would like to be able to consult for such reasons. Multivariate analysis shows that increasing age (21-24 years, odds ratio [OR] = 0.442, P value < 0.05); 25-33 years, OR = 0.190, P value < 0.001), practicing Christian religion (OR = 0.331, P value < 0.1), being insured (OR = 0.398, P value < 0.05), having a father with primary education level (OR = 0.320, P value < 0.05) were protective factors. In contrast, the size of the households [6-8 members, OR = 2.763, P value < 0.1), and the student's income (Q2, OR = 3.136, P value < 0.05; Q3, OR = 2.993, P value < 0.05; Q4, OR = 4.433, P value < 0.001) favoured a higher probability of non-use of gynaecological care. CONCLUSION: Gynaecological needs are real among young women, and gynaecological health promotion is a necessity among this cohort. Quality health promotion can be achieved practically through the enlargement of health insurance, and partnership with healthcare professionals as well as community/religious leaders. This would further demystify biases related to seeking gynaecological care.

BACKGROUND: The charity foundation Association Soutien Enfants Togo started a child health care (CHC) centre in Togo that was modelled after the Dutch high-quality CHC system to improve child health. AIM: To describe health care data of children who visited the centre. SUBJECTS AND METHODS: Data were routinely collected between October 2010-July 2017. Outcomes were completed vaccinations, growth, development, lifestyle, physical examination, and laboratory testing results. RESULTS: In total, 8,809 children aged 0-24 years were available. Half (47.5%) of children aged 0-4 years did not receive all eligible free vaccinations from the government. The proportions of stunted children (all) or with a developmental delay (0-4 years) were 10.1% and 9.5%, respectively. In total, 40-50% of all children did not wash their hands with soap after toilet or before eating, or did not use clean drinking water. Furthermore, 5.1-6.6% had insufficient vision, high eye pressure or hearing loss. Sickle cell disease was detected in 5.3%. CONCLUSION: A large group of children in need of prevention and early treatment were detected, informed and treated by the centre. Further research is needed to confirm if this strategy can improve children's health in Sub-Saharan Africa. Our data are available for further research.

BACKGROUND: Most Togolese population earns their income from informal sector, and they are very often exposed to health outcomes. Cash transfers impact healthcare utilization by improving household's social capital, socio-economic status, lifestyle choice, and physical health. The aim of this paper was to analyse the impact of unconditional cash transfers on health care utilisation in informal sector households. METHODS: We used the propensity-score method to compare health care utilisation by households that received cash transfers from nonbeneficiary households and simulated a potential confounder to assess the robustness of the impacts of the estimated treatment (i.e., cash transfer). Data were obtained from a national survey that covered 1405 households. RESULTS: The results show that women benefited the most from cash transfers (73.1%). Our estimates indicate that health care utilisation increased by 28.3% among workers in the informal sectors who benefited from unconditional cash transfers compared to nonbeneficiaries. The greatest impact was found on agriculture households with an increase by 31.3% in the health care utilisation. In general, cash transfer beneficiaries are more likely to use public health centres; there was an increase in public health facility attendance of 21.3%. CONCLUSIONS: Cash transfers are a valuable social protection instrument that improve health care utilisation of populations in the informal sector. Policymakers could use cash transfer as the infusion of income and/or assets that may impact health outcomes. Cash transfers are an opportunity to alleviate barriers of access to health care by older people. Future research must examine impact of cash transfer on health of vulnerable groups such as older people, children, and people with disabilities.

No data about antiretroviral (ARV) treatment coverage and virological response are available among key populations (female sex workers [FSW] and Men having Sex with Men [MSM]) in Togo. This study aimed to both describe Human Immunodeficiency Virus (HIV) immunovirological status and evaluate the pertinence of an original algorithm combining pharmacology (PK) and viral load (VL) to identify subjects at risk of ARV drug resistance. A cross-sectional multicentric study was conducted in 2017 in Togo. Our PK-virological algorithm (PK-VA) defines subjects at risk of resistance when exhibiting both detectable plasma drug concentrations and VL > 200 c/mL. Among the 123 FSW and 136 MSM included, 50% and 66% were receiving ARV, with 69% and 80% of them successfully-treated, respectively. Genotypes showed drug-resistance mutation in 58% and 63% of nonvirologically controlled (VL > 200 c/mL) ARV-treated FSW and MSM, respectively. PK-VA would have enabled to save 75% and 72% of genotypic tests, for FSW and MSM, respectively. We reported first data about HIV care cascade among key populations in Togo, highlighting they are tested for HIV but linkage to care remains a concern. Furthermore, 70%-80% of ARV-treated participants experienced virological success. In limited resources settings, where genotyping tests are beyond reach, PK-VA might be an easiest solution to sort out patients needing ARV adaptation due to resistance.

BACKGROUND: Malaria is the leading cause of morbidity and mortality among infants and children under-five in sub-Saharan Africa. In the Sahel, seasonal malaria chemoprevention (SMC) is delivered door-to-door in monthly cycles. In each cycle, children are administered sulfadoxine-pyrimethamine (SP) plus amodiaquine (AQ) on Day 1 by community distributors, and AQ on Day 2 and Day 3 by caregivers. Non-adherence to AQ administration by caregivers has implications for emergence of antimalarial resistance. METHODS: Predictors of non-adherence to administration of AQ on Day 2 and Day 3 among caregivers of children aged 3-59 months who had received Day 1 SP and AQ during the last 2020 SMC cycle (n = 12,730) were analysed using data from SMC coverage surveys in Nigeria, Burkina Faso and Togo, and fitting multivariate random-effects logistic regression models. RESULTS: Previous adverse reaction to SMC medicines by eligible children (OR: 0.29, 95% CI 0.24-0.36, p < 0.001), awareness of the importance of administering Day 2 and Day 3 AQ (OR: 2.19, 95% CI 1.69-2.82, p < 0.001), caregiver age, and home visits to caregivers delivered by the Lead Mothers intervention in Nigeria (OR: 2.50, 95% CI 1.93-2.24, p < 0.001), were significantly associated with caregiver adherence to Day 2 and Day 3 AQ administration. CONCLUSIONS: Increasing caregivers' knowledge of SMC and interventions such as Lead Mothers have the potential to improve full adherence to AQ administration.

BACKGROUND: Malaria remains the leading cause of mortality and morbidity in young children in sub-Saharan Africa. To prevent malaria in children living in moderate-to-high malaria transmission areas, the World Health Organization has recommended perennial malaria chemoprevention (PMC). Prior to piloting PMC implementation in southern Togo, a household survey was conducted to estimate malaria infection prevalence in children under 2 years of age (U2). METHODS: A cross-sectional community-based household survey was conducted in the Haho district in the Togo Plateaux region. A three-stage random sampling method was used to select study participants aged 10-23 months whose caretakers gave informed consent. The prevalence of Plasmodium infection, defined as a positive rapid diagnostic test (RDT), was estimated with 95% confidence interval (CI). Clinical malaria was defined as having a positive RDT plus fever (≥ 37.5 °C) or history of fever in the last 24 h. Mixed-effects logistic regression models were used to assess the child's, caretaker's, and household's factors associated with malaria infection. RESULTS: A total of 685 children were included in the survey conducted January-February in 2022 (dry season). Median age was 17 months (interquartile range: 13-21). About 80% of the children slept under a bed net the night before the interview. Malaria infection prevalence was 32.1% (95% CI 27.7-37.0) with significant area variation (cluster range: 0.0-73.3). Prevalence of clinical malaria was 15.4% (95% CI 12.2-19.2). Children whose caretakers were animist (aOR: 1.71, 95% CI 1.19-2.46) and those living in mother-headed households (aOR: 2.39, 95% CI 1.43-3.99) were more likely to have a positive RDT. Living more than 5 km away from the nearest health facility (aOR: 1.60, 95% CI 1.04-2.44) and presence of two or more under-5-years children in the household (aOR: 1.44, 95% CI 1.01-2.07) were also associated with increased risk of infection. CONCLUSION: One-third of the children U2 who participated in this survey had malaria infection, thus PMC could be a promising strategy to reduce malaria burden in young children in Plateaux region. Reinforcement of outreach services and targeting the poorest households should be prioritized to reduce the inequity in malaria prevention in children exposed to the infection.

BACKGROUND: There is almost no data on the circulation of SARS-CoV-2 among street adolescents. We conducted a study to document the immunization status of street adolescents in Togo against different variants of SARS-CoV-2. METHODS: A cross-sectional study was carried out in 2021 in Lomé, the city with the highest number of COVID 19 cases in Togo (60%). Adolescents aged 13- and 19 years old living on the street were eligible for inclusion. A standardized questionnaire was administered face-to-face to adolescents. A sample of blood was taken and aliquots of plasma were transported to the virology laboratory of the Hôpital Bichat-Claude Bernard (Paris, France). SARS-CoV-2 anti-S and anti-N IgG were measured using chemiluminescent microparticle immunoassay. A quantitative miniaturized and parallel-arranged ELISA assay was used to detect IgG antibodies specifically directed against the different SARS-CoV-2 Variants of Concern (VOC). RESULTS: A total of 299 street adolescents (5.2% female), median age 15 years, interquartile range (14-17 years), were included in this study. The prevalence of SARS-CoV-2 infection was 63.5% (95%CI: 57.8-69.0). Specific-IgG against the ancestral Wuhan strain was developed by 92.0% of subjects. The proportion of patients being immunized against each VOC was 86.8%, 51.1%, 56.3%, 60.0, and 30.5% for the Alpha, Beta, Gamma, Delta, and Omicron VOCs, respectively. CONCLUSION: This study showed a very high prevalence with approximately 2/3 of Togolese street adolescents having antibodies to SARS-CoV-2 due to a previous infection. These results confirm an under-reporting of COVID-19 cases in Togo, questioning the hypothesis of low virus circulation in Togo and even in Africa.

BACKGROUND: vulvar cancer, once predominantly diagnosed in older women, is increasingly being diagnosed in younger individuals, due to Human Papillomavirus (HPV) infection. Our study aimed to describe the epidemiological and histopathological aspects of vulvar cancer in Togo and its associated factors. METHODS: This was a cross-sectional study, conducted on vulvar cancer cases histologically diagnosed at the Pathological Laboratory of Lomé over a period of 17-years (2005-2021). Parameters investigated included age, occupation, risk factors, sample nature, macroscopic tumor aspects, histological types, therapeutic intervenions, and prognostic outcomes. RESULTS: A total of 32 cases of vulvar cancer were collected, yieding an annual frequency of 1.88 cases. The average age of the patients was 48±14.12 years with extremes of 27 years and 82 years. Housewives accounted for the largest proportion of cases (37.5%). Among the 32 cases, 27 had identifiable risk factors, with HPV infection being the most prevalentr (33.3%). The ulcero-budding aspect was most frequently observed, and squamous cell carcinoma was the most common histological type, with the majority being well differentiated (89.3%). Statistically significant associations were found between risk factors and histological types, risk factors and degrees of differentiation, as well as between histological types and good differentiation of vulvar cancers. The 3-year survival was estimated at 78.13%. CONCLUSION: The incidence of vulvar cancer is increasing in Togo, particularly among young, primarily due to HPV infection.

BACKGROUND: Breast cancer is the most frequently diagnosed cancer in women worldwide. The objective of this study was to identify factors associated with late diagnosis of breast cancer in Togolese women. METHODS: We conducted a prospective cross-sectional study with descriptive and analytical purposes on cases of breast cancer in women in 2021, in Togo. The patients included in this study were women followed in the gynecology department for stages III and IV breast cancer. RESULTS: We included 62 cases of breast cancer. The average age of the patients was 38.6 ± 12.5 years with extremes of 17 and 76 years. The breast nodule was the most common reason for consultation in 75.8% of cases. The histological types diagnosed were invasive carcinoma of non-specific type (58; 93.55%), mucinous carcinoma (3; 4.84%) and lobular carcinoma (1; 1.61%). For the stage of the cancer, 43 patients were stage III (69.4%) and 19 stage IV (30.6%). In multivariate analysis, the factors associated with late diagnosis of breast cancer were: fear of diagnosis (aOR = 1.29; p = 0.0014), long delay in diagnosis (aOR = 2.62; p = 0.0001) and failure to perform breast self-examination (aOR = 1.68; p = 0.0022). CONCLUSION: The fear of the diagnosis, the absence of self-examination of the breasts and the use of traditional treatment and self-medication in first intention constituted the essential factors of the late diagnosis of breast cancer. Strategies should be put in place at the national level to impact on these factors for an early diagnosis of breast cancer.

The infestation of the fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in Africa since 2016 has been a major threat to maize production. Previous studies in Togo and Ghana from 2016 to 2018 did not correlate FAW infestation to yield losses. Thus, the aim of this study which assesses the impact of FAW infestation by inspecting 150 maize farms throughout the five Agro-Ecological Zones (AEZs) of Togo for FAW plant damage, and third instar larvae were used to infest 10-day-old maize plants in netted plots under controlled conditions at an experiment station (Station d'Expérimentations Agronomiques de Lomé) in 2019 and 2020. As control plots at the experiment station, plots were both netted and treated with emamectin benzoate, simply netted, or open to natural infestation. The number of larvae, egg masses, percent damaged plants, and damage proportions of leaves and ears were scored until harvest. Infestations and damages on maize plant throughout Togo were similar between the two years but were higher in the southern part of the county (AEZ5). At the experiment station, the yield losses were significantly considerable and increased from 25% infestation. The losses were 0.37 t ha-1 for 25% infestation, 0.34 t ha-1 for 30%, 0.59 t ha-1 for the open plots, 0.70 t ha-1 for simple netted and 50% infestation, 1.03 t ha-1 for 75%, and 1.27 t ha-1 for 100% infestation. This current study suggested thorough inspection on maize farms to set off management practices from 25% of infestation.

In Togo, family planning (FP) use remains low; only 24.1% of married woman ages 15 to 49 use modern FP. The West Africa Breakthrough ACTION (WABA) project developed the Confiance Totale radio campaign, which used a Saturation+ approach to encourage FP use. This study presents the results of an evaluation of Confiance Totale which investigates associations between campaign exposure and outcomes of interest. Following the broadcasts, the team conducted a cross-sectional household survey among 2,200 respondents ages 18 to 49. Combined and sex-stratified multivariable models predicting outcomes of interest controlled for sex, age, site, marital status, educational attainment, religion, and economic status. Upon hearing a campaign jingle, approximately 45% of participants had heard the campaign. Exposure to the campaign was associated with many ideational and behavioral outcomes including current use of a facility-dependent FP method (OR = 1.77, p < .001). In stratified models, several outcomes were significantly associated with exposure in the women-only models but not in the men-only models. Exposure to Confiance Totale was associated with nearly all ideational and behavioral outcomes of interest, particularly among women. This demonstrates that high dosage broadcasting may be effective in promoting confidence in the health system and improving perceptions of FP.

BACKGROUND: Proper utilization of maternal healthcare services plays a major role on pregnancy and birth outcomes. In sub-Saharan Africa, maternal and child mortality remains a major public health concern, especially in least developed countries such as Togo. In this study, we aimed to analyze factors associated with use of maternal health services among Togolese women aged 15-49 years. METHODS: This study used data from third round of nationally representative Demographic and Health Survey conducted in Togo in 2013. Analysis included 4,631 women aged 15-49 years. Outcome variables were timely first antenatal care (ANC) visits, adequate ANC4 + visits, and health facility delivery. Data were analyzed using Stata version 16. RESULTS: Overall, proportion of maternal healthcare utilization was 27.53% for timely first ANC visits, 59.99% for adequate ANC visits, and 75.66% for health facility delivery. Our multivariable analysis showed significant differences among women in highest wealth quintile, especially in rural areas with increasing odds of timely first ANC visits (Odds ratio (OR) = 3.46, 95% CI = 2.32,5.16), attending adequate ANC visits (OR = 2.19, 95% CI = 1.48,3.24), and delivering in health facilities (OR = 8.53, 95% CI = 4.06, 17.92) compared to those in the poorest quintile. Also, women with higher education had increased odds of timely first ANC visits (OR = 1.37, 95% CI = 1.11,1.69), and attending adequate ANC visits (OR = 1.73, 95% CI = 1.42,2.12) compared to those with no formal education. However, having higher parity and indigenous beliefs especially in rural areas decreased odds of using healthcare services. CONCLUSIONS: Findings from this study showed that socio-economic inequality and socio-cultural barriers influenced the use of maternal healthcare services in Togo. There is therefore a need to improve accessibility and the utilization of maternal healthcare services through women's economic empowerment and education to reduce the barriers.
Utilization of healthcare services by women of childbearing age has been shown to reduce maternal and child mortality. However, in sub-Saharan Africa, maternal and child mortality remains a major public health issue. This is especially the case in Togo, one of the smallest countries in West Africa. The objective of this study was to assess the factors associated with utilization of maternal healthcare services among Togolese women aged 1549 years. This was a cross-sectional study that used data from the Togo 2013 Demographic and Health Survey, a nationally representative household survey of women of childbearing age in Togo. Findings from the current study showed that the overall proportion of maternal healthcare utilization was 27.53% for timely first antenatal care visits, 59.99% for adequate antenatal care visits, and 75.66% for health facility delivery. Also, this study found that socio-economic inequality and socio-cultural barriers influenced the use of maternal healthcare services in Togo. For instance, women in the highest wealth quintile, those with higher education, and those who were covered by health insurance had higher odds of utilizing maternal healthcare service. Whereas, women who had indigenous beliefs, those from other ethnicities, who lived in the Savanes and Plateaux regions, as well as those with higher parity had lower odds of using maternal healthcare services. The results indicate that there is an urgent need to promote women's economic empowerment and education to improve accessibility and the utilization of maternal healthcare services.

This study aimed to evaluate the prevalence of E. coli, Pseudomonas spp., and Enterococcus spp. in Nile tilapia broodstock farms in Togo and their association with fish diseases. In total, 60 samples were collected from two tilapia broodstock farms, including 40 broodstock tilapia and 20 water samples. Each farm had concrete tanks supplied with water from two drills. Of the 40 fish samples, 20 were healthy, and the other 20 were diseased. Microbiological analysis of samples was conducted using standardized methods. The study revealed significant contamination in all collected water samples, detecting multiple bacterial populations. Bacterial infections were more prevalent in symptomatic fish, with 85% exhibiting co-infections (df = 1, χ2 = 7.03, p = 0.008). Contamination levels varied among sample types, with higher counts observed in wastewater (E. coli: 0-300 CFU/mL, Pseudomonas spp.: 3-300 CFU/mL, Enterococcus spp.: 0-55 × 102 CFU/mL) compared to drilling water (Pseudomonas spp.: 0-300 CFU/mL, E. coli: 3-400 CFU/mL, Enterococcus spp.: 0-14 × 102 CFU/mL), and intestinal samples (E. coli: 0-120 × 102 CFU/mL, Enterococcus spp.: 0-170 × 102 CFU/mL, Pseudomonas spp.: 0-60 × 102 CFU/mL) (df = 21, χ2 = 59.31, p < 0.000). Our findings emphasize the significant prevalence of pathogenic bacteria in Nile tilapia broodstock farms in Togo, highlighting the importance of water quality management and infection control strategies. Further studies are required to develop appropriate prevention strategies.
