COVID-19 vaccines and a perspective on Africa.

Vaccines have dramatically changed the COVID-19 pandemic. Over 30 vaccines that were developed on four main platforms are currently being used globally, but a deep dissection of the immunological mechanisms by which they operate is limited to only a few of them. Here, we review the evidence describing specific aspects of the modes of action of COVID-19 vaccines; these include innate immunity, trained innate immunity, and mucosal responses. We also discuss the use of COVID-19 vaccines in the African continent which is ridden with inequality in its access to vaccines and vaccine-related immunological research. We argue that strengthening immunology research in Africa should inform on fundamental aspects of vaccination, including the relevance of genetics, trained innate immunity, and microbiome diversity.

Assessing the resilience of HIV healthcare services provided to adolescents and young adults after the COVID-19 pandemic in the city of Beira (Mozambique): an interrupted time series analysis.

BACKGROUND: The COVID-19 pandemic has put the provision of health services globally at risk. In Sub-Saharan Africa, it had a major impact on HIV services. However, there is a lack of data on the post-pandemic period. This study aims to evaluate the resumption of HIV services and retention in care for adolescents and young people in the period following the COVID-19 pandemic. METHODS: A retrospective cohort study was conducted using interrupted time series analysis. Three periods were considered: pre-pandemic (form June 2019 to March 2020), pandemic (form April 2020 to March 2022) post-pandemic (from April 2022 to March 2023). Six outcome measures were considered: number of outpatient visits, HIV tests, HIV positivity ratio, the antiretroviral treatment (ART) non-adherence ratio, recall ratio, and the return ratio for adolescent and young adults on ART. RESULTS: During the study period, 447,515 outpatient visits and 126,096 HIV tests were recorded. After a reduction at the beginning of the pandemic period, both visits and tests increased during the pandemic (p < 0.05) and decreased in the post-pandemic (p < 0.05), recovering the pre-pandemic trends. The HIV positivity ratio slightly decreased from 3.3% to 1.7% during the study period (p < 0.05). The ART non-adherence ratio decreased from 23.4% to 2.4% throughout the study period (p < 0.05), with a drop at the beginning of the post-pandemic period (p < 0.05). The recall ratio increased during the study period (p < 0.05) with a drop at the beginning of the pandemic and post-pandemic periods (p < 0.05). The return ratio decreased at the beginning of the pandemic (p < 0.05) but returned to the pre-pandemic ratio in the post-pandemic period. CONCLUSIONS: The post-pandemic values of the investigated outcomes were comparable to pre-pandemic period, or even improved. Differently from other services, such as the community activities, that have been severely affected by COVID-19 pandemic, the HIV service system has shown resilience following emergency situation.

A multicentre neonatal manikin study showed a large heterogeneity in tactile stimulation for apnoea of prematurity.

AIM: Apnoea of prematurity requires prompt intervention to prevent long-term adverse outcomes, but specific recommendations about the stimulation approach are lacking. Our study investigated the modalities of tactile stimulation for apnoea of prematurity in different settings. METHODS: In this multi-country observational prospective study, nurses and physicians of the neonatal intensive care units were asked to perform a tactile stimulation on a preterm neonatal manikin simulating an apnoea. Features of the stimulation (body location and hand movements) and source of learning (training course or clinical practice) were collected. RESULTS: Overall, 112 healthcare providers from five hospitals participated in the study. During the stimulation, the most frequent location were feet (72%) and back (61%), while the most frequent techniques were rubbing (64%) and massaging (43%). Stimulation modalities different among participants according to their hospitals and their source of learning of the stimulation procedures. CONCLUSION: There was a large heterogeneity in stimulation approaches adopted by healthcare providers to counteract apnoea in a simulated preterm infant. This finding may be partially explained by the lack of specific guidelines and was influenced by the source of learning for tactile stimulation.

SARS-CoV-2 seroprevalence and associated factors, based on HIV serostatus, in young people in Sofala province, Mozambique.

INTRODUCTION: In Sofala province (Mozambique), young people living with HIV (YPLHIV) are estimated at 7% among people aged 15-24 years. Even though the COVID-19 pandemic threatened HIV health services, data on the impact of COVID-19 on YPLHIV people are lacking. This study aimed at exploring the seroprevalence of SARS-CoV-2 and associated factors among young people based on their HIV status. METHODS: A cross-sectional study was conducted, including people aged 18-24 attending a visit at one of the adolescent-friendly health services in Sofala province between October and November 2022. People vaccinated against SARS-COV-2 or YPLHIV with WHO stage III-IV were excluded. A SARS-CoV-2 antibodies qualitative test and a questionnaire investigating socio-demographic and clinical characteristics were proposed. SARS-CoV-2 seroprevalence was calculated with Clopper-Pearson method. The odds ratio (OR) of a positive SARS-CoV-2 antibodies test was estimated through multivariable binomial logistic regression. RESULTS: In total, 540 young people including 65.8% women and 16.7% YPLHIV participated in the survey.. The mean age was 20.2 years (SD 2.0). Almost all the sample (96.1%) reported adopting at least one preventive measure for COVID-19. The weighted seroprevalence of SARS-CoV-2 in the whole sample was 46.8% (95%CI 42.6-51.2) and 35.9% (95%CI 25.3-47.5) in YPLHIV. The adjusted OR of testing positive at the SARS-CoV-2 antibodies test was higher in students compared to workers (aOR:2.02[0.95CI 1.01-4.21]) and in those with symptoms (aOR:1.52[0.95CI 1.01-2.30]). There were no differences based on HIV status(aOR:0.663[95%CI 0.406-1.069]). Overall, COVID-19 symptoms were reported by 68 (28.2%) people with a positive serological SARS-CoV-2 test and by 7 (21.7%) YPLHIV (p = 0.527). No one required hospitalization. CONCLUSIONS: SARS-CoV-2 seroprevalence was 46.8% without differences in risk of infection or clinical presentation based on HIV status. This result may be influenced by the exclusion of YPLHIV with advanced disease. The higher risk among students suggests the schools' role in spreading the virus. It's important to continue monitoring the impact of COVID-19 on YPLHIV to better understand its effect on screening and adherence to treatment.

International medical electives in Sub-Saharan Africa: experiences from a 19-year NGO-driven initiative.

BACKGROUND: Mainstream medical education remains largely focused on national health issues. Therefore, in order to expose medical students to international health issues, it is beneficial to facilitate international medical electives. METHODS: This article describes the Junior Project Officer (JPO) program, a medical experience based on clinical electives in Sub-Saharan Africa, supported by a Non-Governmental Organisation (NGO). Residents spend 6 months as part of a multidisciplinary medical team in Africa. A post-elective online survey was administered to all who participated in the program in the period 2002-2020. The questionnaire comprised three domains: (i) general and pre-departure information; (ii) the experience; (iii) the post-experience. RESULTS: Questionnaires were received from 157/241 subjects, a response rate of 65%. The most common specialties were pediatrics, public health, and internal medicine. Of all, 87% carried out clinical activities; 45% also worked in the management of health services, and 60% carried out research activities. About 64% reported difficulties linked to a lack of equipment, different ways of working (57%), and exposure to situations for which they did not feel technically prepared (56%). In 25% of cases, residents reported that their school's attitude to their doing the elective was not positive: upon their return, over 50% felt that their experience was not sufficiently valued by their institution. Respondents considered the experience important for professional and personal growth (93% and 80% respectively ). Forty-two participants (27%) reported that the experience had a significant impact on their future career choices. CONCLUSION: Despite the difficulties encountered, a well-structured experience in international health can have a positive impact on residents, professionally and personally. Key factors behind the positive outcomes are the substantial length (6 months) of the experience, and the long term working relationships between the sending and receiving institutions. The schools in Italy that provide the students for the electives need to see more evidence that international electives are worth the investment.

Impact of antimalarial resistance and COVID-19 pandemic on malaria care among pregnant women in Northern Uganda (ERASE): protocol of a prospective observational study.

BACKGROUND: Uganda accounts for 5% of all malaria cases and deaths reported globally and, in endemic countries, pregnancy is a risk factor for both acquisition of P. falciparum infection and development of severe malaria. In recent years, malaria control has been threatened by COVID-19 pandemic and by the emergence, in Northern Uganda, of both resistance to artemisinin derivatives and to sulfadoxine-pyrimethamine. METHODS: In this facility-based, prospective, observational study, pregnant women will be recruited at antenatal-care visits and followed-up until delivery. Collected data will explore the incidence of asymptomatic parasitemia and malaria-related outcomes, as well as the attitudes towards malaria prevention, administration of intermittent preventive treatment, healthcare seeking behavior and use of insecticide-treated nets. A subpopulation of women diagnosed with malaria will be recruited and their blood samples will be analyzed for detection of genetic markers of resistance to artemisinin derivatives and sulfadoxine-pyrimethamine. Also, to investigate the impact of COVID-19 on malaria care among pregnant women, a retrospective, interrupted-time series will be conducted on at the study sites for the period January 2018 to December 2021. DISCUSSION: The present study will explore the impact of COVID-19 pandemic on incidence of malaria and malaria-related adverse outcomes, along with the prevalence of resistance to artemisinin derivatives and to sulfadoxine-pyrimethamine. To our knowledge, this is the first study aiming to explore the combined effect of these factors on a cohort of pregnant women. TRIAL REGISTRATION: This study has been registered on the ClinicalTrials.gov public website on 26th April, 2022. CLINICALTRIALS: gov Identifier: NCT05348746.

Comparison of alternative gestational age assessment methods in a low resource setting: a retrospective study.

BACKGROUND: Accurate gestational age (GA) determination allows correct management of high-risk, complicated or post-date pregnancies and prevention or anticipation of prematurity related complications. Ultrasound measurement in the first trimester is the gold standard for GA determination. In low- and middle-income countries elevated costs, lack of skills and poor maternal access to health service limit the availability of prenatal ultrasonography, making it necessary to use alternative methods. This study compared three methods of GA determination: Last Normal Menstrual Period recall (LNMP), New Ballard Score (NBS) and New Ballard Score corrected for Birth Weight (NBS + BW) with the locally available standard (Ultrasound measurement in the third trimester) in a low-resource setting (Tosamaganga Council Designated Hospital, Iringa, Tanzania). METHODS: All data were retrospectively collected from hospital charts. Comparisons were performed using Bland Altman method. RESULTS: The analysis included 70 mother-newborn pairs. Median gestational age was 38 weeks (IQR 37-39) according to US. The mean difference between LNMP vs. US was 2.1 weeks (95% agreement limits - 3.5 to 7.7 weeks); NBS vs. US was 0.2 weeks (95% agreement limits - 3.7 to 4.1 weeks); NBS + BW vs. US was 1.2 weeks (95% agreement limits - 1.8 to 4.2 weeks). CONCLUSIONS: In our setting, NBS + BW was the least biased method for GA determination as compared with the locally available standard. However, wide agreement bands suggested low accuracy for all three alternative methods. New evidence in the use of second/third trimester ultrasound suggests concentrating efforts and resources in further validating and implementing the use of late pregnancy biometry for gestational age dating in low and middle-income countries.

Prognostic role of TOPS in ambulance-transferred neonates in a low-resource setting: a retrospective observational study.

BACKGROUND: Assessing the severity of transferred neonates at admission can improve resource allocation. This study evaluated the role of TOPS (illness severity score including temperature, oxygen saturation, skin perfusion and blood sugar) in predicting mortality in neonates transferred by ambulance in a low-resource setting. METHODS: The study was conducted at Beira Central Hospital (Mozambique). Infants who were transferred by ambulance to the Neonatal Intensive Care Unit between 16th June and 16th October 2021 were included. The association between TOPS and mortality was investigated with a logistic regression model. Receiver-operating characteristics (ROC) curve was derived for TOPS; area under the ROC curve, sensitivity and specificity were calculated. RESULTS: In-transport mortality was 2/198 (1.0%) and in-hospital mortality was 75/196 (38.3%). Median gestational age and birthweight were 38 weeks and 2600 g. Main causes of admission were asphyxia (29.3%), prematurity (25.3%) and sepsis (22.7%). Hypothermia and oxygen desaturation at admission were 75.8% and 32.3%. TOPS ≥ 1 was associated with increased mortality risk (odds ratio 7.06. 95% confidence interval 1.90 to 45.82), with 0.97 sensitivity and 0.26 specificity. CONCLUSIONS: The high mortality rate calls for interventions and quality initiative studies to improve the transfer process and the conditions at admission. TOPS can be used to identify neonates at risk of mortality and concentrate efforts of health care providers. Interventions preventing hypothermia and oxygen desaturation should be implemented in pre-transport stabilization and care during transport.

Influence of a quality improvement intervention on rehabilitation outcomes of children (6-24 months) with acute malnutrition: a retrospective study in rural Angola.

BACKGROUND: Defaulting is the most frequent cause of Community Management of Acute Malnutrition (CMAM) program failure. Lack of community sensitization, financial/opportunity costs and low quality of care have been recognized as the main driving factors for default in malnutrition programs. The present study aimed to evaluate if a logistic reorganization (generic outpatient department, OPD vs dedicated clinic, NRU) and a change in management (dedicated vs non dedicated staff) of the follow-up of children between 6 and 24 months of age with acute malnutrition, can reduce the default, relapse and readmission rate and increase the recovery rate. METHODS: Retrospective observational study on the impact of quality improvement interventions on rehabilitation outcomes of children (6-24 months) with acute malnutrition, admitted at the Catholic Mission Hospital of Chiulo (Angola) from January 2018 to February 2020. Main outcome measures were recovery rate, the default rate, the relapse rate, and the readmission rate. RESULTS: The intervention was associated with a decrease in the default rate from 89 to 76% (p = 0.02). Recovery rate was 69% in OPD and 88% in NRU (p = 0.25). Relapse rate was nil. CONCLUSIONS: The present study supports the hypothesis that an improvement in quality of care can positively influence the rehabilitation outcomes of malnourished children. Further studies are needed to identify children at risk of low adherence to follow-up visits to increase the effectiveness of rehabilitation programs.

Medical Electives in Sub-Saharan Africa: A 15-Year Student/NGO-Driven Initiative.

Medical schools are developing global health programmes, and medical students are requesting global health training and creating opportunities when these are not provided by medical schools. This article described the Wolisso Project (WP), a medical experience on clinical electives in Sub-Saharan Africa, driven by a collaboration between a student organisation and a Nongovernmental Organization (NGO). Preclinical medical students spent 4 weeks as part of a multidisciplinary medical team in Africa. Post-elective questionnaires were administered to all subjects who participated in the project. Of all, 141 students responded to the questionnaire. The participants came from 30 Italian universities. The main difficulties reported are due to the lack of resources for the exercise of the medical activity, and difficulties related to language and communication. The African experience had a positive impact on the progress of the studies upon return, with an increase in determination and motivation. The experience had also positive influences on the future professional choices and carriers. The experience seems to contribute not only to the professional growth, but also to the personal development. A key factor in the positive outcomes of this experience is it being implemented by an NGO with long-term working relationships with the African populations. Another is that the project is carried out in health facilities where NGO staff have been working for a long time. These factors reduce the potential risks connected with this type of experience. They ensure a satisfactory level of supervision, the lack of which has been a serious problem in many similar experiences. A well-structured, mentored experience in international health can have a positive impact on preclinical students' attitudes, including their compassion, volunteerism, and interest in serving underserved populations. Only a small number of Italian universities facilitate pre-graduate medical elective experiences in LMICs. The WP seems to be attempting to compensate for the lack of international experience in LMICs offered by universities. Italian medical schools should incorporate changes in their curricula to train socially responsible physicians.

Modeling the interplay between demography, social contact patterns, and SARS-CoV-2 transmission in the South West Shewa Zone of Oromia Region, Ethiopia.

BACKGROUND: COVID-19 spread may have a dramatic impact in countries with vulnerable economies and limited availability of, and access to, healthcare resources and infrastructures. However, in sub-Saharan Africa, a low prevalence and mortality have been observed so far. METHODS: We collected data on individuals' social contacts in the South West Shewa Zone (SWSZ) of Ethiopia across geographical contexts characterized by heterogeneous population density, work and travel opportunities, and access to primary care. We assessed how socio-demographic factors and observed mixing patterns can influence the COVID-19 disease burden, by simulating SARS-CoV-2 transmission in remote settlements, rural villages, and urban neighborhoods, under school closure mandate. RESULTS: From national surveillance data, we estimated a net reproduction number of 1.62 (95% CI 1.55-1.70). We found that, at the end of an epidemic mitigated by school closure alone, 10-15% of the population residing in the SWSZ would have been symptomatic and 0.3-0.4% of the population would require mechanical ventilation and/or possibly result in a fatal outcome. Higher infection attack rates are expected in more urbanized areas, but the highest incidence of critical disease is expected in remote subsistence farming settlements. School closure contributed to reduce the reproduction number by 49% and the attack rate of infections by 28-34%. CONCLUSIONS: Our results suggest that the relatively low burden of COVID-19 in Ethiopia observed so far may depend on social mixing patterns, underlying demography, and the enacted school closures. Our findings highlight that socio-demographic factors can also determine marked heterogeneities across different geographical contexts within the same region, and they contribute to understand why sub-Saharan Africa is experiencing a relatively lower attack rate of severe cases compared to high-income countries.

Impact of socio-economic factors on Tuberculosis treatment outcomes in north-eastern Uganda: a mixed methods study.

BACKGROUND: Tuberculosis (TB) is a major public health problem and at 48%, Karamoja in North-Eastern Uganda has the lowest treatment success rate nationally. Addressing the social determinants of TB is crucial to ending TB. This study sought to understand the extent and ways in which socio-economic factors affect TB treatment outcomes in Karamoja. METHODS: We conducted a convergent parallel mixed methods study in 10 TB Diagnostic and Treatment Units. The study enrolled former TB patients diagnosed with drug-susceptible TB between April 2018 and March 2019. Unit TB and laboratory registers were reviewed to identify pre-treatment losses to follow-up. Four focus group discussions with former TB patients and 18 key informant interviews with healthcare workers were conducted. Principle component analysis was used to generate wealth quintiles that were compared to treatment outcomes using the proportion test. The association between sociodemographic characteristics and TB treatment outcomes was evaluated using the chi-square test and multiple logistic regression. RESULTS: A total of 313 participants were randomly selected from 1184 former TB patients recorded in the unit TB registers. Of these, 264 were contacted in the community and consented to join the study: 57% were male and 156 (59.1%) participants had unsuccessful treatment outcomes. The wealthiest quintile had a 58% reduction in the risk of having an unsuccessful treatment outcome (adj OR = 0.42, 95% CI 0.18-0.99, p = 0.047). People who were employed in the informal sector (adj OR = 4.71, 95% CI 1.18-18.89, p = 0.029) and children under the age of 15 years who were not in school or employed (adj OR = 2.71, 95% CI 1.11-6.62, p = 0.029) had significantly higher odds of unsuccessful treatment outcome. Analysis of the pre-treatment loss to follow-up showed that 17.2% of patients with pulmonary bacteriologically confirmed TB did not initiate treatment with a higher proportion among females (21.7%) than males (13.5%). Inadequate food, belonging to migratory communities, stigma, lack of social protection, drug stock-outs and transport challenges affected TB treatment outcomes. CONCLUSIONS: This study confirmed that low socio-economic status is associated with poor TB treatment outcomes emphasizing the need for multi- and cross-sectoral approaches and socio-economic enablers to optimise TB care.

Nutritional education during rehabilitation of children 6-24 months with acute malnutrition, under unavailability of therapeutic/supplementary foods: a retrospective study in rural Angola.

BACKGROUND: Dietary counseling can play an important role in managing child malnutrition but is often inadequate or absent. Moreover, little emphasis is given to the usefulness of local available foods in the rehabilitation of malnourished children. This study aimed to evaluate the adherence and effectiveness of nutritional education during rehabilitation of children (6-24 months) with acute malnutrition, in a setting of unavailability of therapeutic/supplementary foods. METHODS: Retrospective observational study on the adherence to dietary counseling and the impact on growth in children 6-24 months who were referred for acute malnutrition at the Catholic Mission Hospital of Chiulo (Angola) from August 2018 to January 2019. Main outcome measures were change in dietary habits and growth gain. RESULTS: Sixty-four out of 120 children returned at first follow-up visit (default rate 47%). A change in dietary habits was reported in 32/64 (50%) children. Changing dietary habits was associated with an improved change in weight gain (MD 9.3 g/kg/day, 95%CI 4.2 to 14.3; p = 0.0005) and in weight/height ratio (MD 1.1 SD, 95%CI 0.7 to 1.4; p < 0.0001). CONCLUSIONS: A change in dietary habits after discharge was noted in only half of the patients who returned at first follow up visit, but it provided some advantages in term of weight gain and weight/height ratio. Further studies are needed to identify children at risk of low adherence to follow-up visits and low compliance to the nutritional recommendations, in order to increase the effectiveness of rehabilitation programs.

Limited agreement between clinical assessment of infant colour at birth and oxygen saturation in a hospital in Ethiopia.

AIM: To evaluate the relationship between clinical assessment of infant colour and oxygen saturation at birth in a low-resource setting. METHODS: Classification of infant colour (cyanotic, pink or unclear) by midwives was compared to pulse-oximeter data at 60-90-120-300 seconds after birth in 60 neonates. RESULTS: Overall, oxygen saturation increased over time (P < .0001) and was different according to infant colour (P < .0001). Median oxygen saturation in pink infants was 87% at 60 seconds (n = 1), 90% (IQR 83-91) at 90 seconds (n = 5), 86% (IQR 81-94) at 120 seconds (n = 11) and 93% (IQR 90-96) at 300 seconds (n = 20). Median oxygen saturation in cyanotic infants was 60% (IQR 45-70) at 60 seconds (n = 52), 64% (IQR 52-69) at 90 seconds (n = 42), 63% (IQR 56-68) at 120 seconds (n = 35) and 66% (IQR 62-74) at 300 seconds (n = 22). Median oxygen saturation in unclear-coloured infants was 57% (IQR 56-60) at 60 seconds (n = 7), 78% (IQR 71-81) at 90 seconds (n = 13), 81% (IQR 79-88) at 120 seconds (n = 14) and 80% (IQR 76-84) at 300 seconds (n = 18). The proportion of infants with unclear colour ranged from 12% to 30%. CONCLUSION: The variability of oxygen saturation among pink and cyanotic infants, and the substantial proportion of unclear infant colour, suggest the possible benefit of the availability of pulse oximetry in low-resource settings.

Heart Rate Determination in Newborns at Risk for Resuscitation in a Low-Resource Setting: A Randomized Controlled Trial.

OBJECTIVE: To compare 2 different methods (auscultation with a stethoscope and umbilical cord palpation) of heart rate (HR) estimation in newborns at risk for resuscitation in a low-resource setting. STUDY DESIGN: Sixty newborns at risk for resuscitation born at the St. Luke Catholic Hospital in Wolisso (Ethiopia) were randomized to HR assessment by auscultation using a stethoscope or umbilical cord palpation. HR was assessed at 60, 90, 120 seconds, and 5 minutes of life. The primary outcome was the agreement of HR obtained by auscultation or palpation compared with the HR determined by electrocardiogram. RESULTS: Mean difference between auscultation using a stethoscope and electrocardiogram was -13 bpm, -4 bpm, -6 bpm, and -10 bpm at 60, 90, 120 seconds, and at 5 minutes of life. Mean difference between palpation and electrocardiogram of was -20 bpm, -25 bpm, -23 bpm, and -31 bpm at 60, 90, 120 seconds, and at 5 minutes of life. The magnitude of the difference between auscultation and electrocardiogram was lower than that between palpation and electrocardiogram over time (P = .007). HR range was correctly identified in 14 out of 16 measurements (87%) with HR <100 bpm. CONCLUSION: HR assessment by auscultation was more accurate compared with cord palpation, but both may provide adequate clinical information to healthcare providers in terms of HR ranges. The clinical advantage of providing a stethoscope in low-resource settings remains to be established. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03854435.

The potential of mobile health clinics in chronic disease prevention and health promotion in universal healthcare systems. An on-field experiment.

BACKGROUND: Mobile health clinics (MHCs) are recognized to facilitate access to healthcare services, especially in disadvantaged populations. Notwithstanding that in Europe a wide-ranging background in mobile screening units for cancer is shared, evidences about MHCs targeting also at other non-communicable diseases (NCDs) in universal health coverage systems are scarce. The aim of this study was to describe the population attracted with a MHC initiative and to assess the potential of this tool in prevention and control of NCDs. METHODS: Our MHC was set up in a railway wagon. Standard body measurements, finger-stick glucose, total cholesterol and blood pressure were recorded. Participants were asked about smoking, physical activity, diet, compliance to national cancer screening programmes and ongoing pharmacological treatment. One-to-one counselling was then provided. RESULTS: Participants (n = 839) showed a higher prevalence of overweight/obesity, insufficient intake of vegetables, sedentary lifestyle, and a lower compliance to cancer screening compared with reference population. Our initiative attracted groups at higher risk, such as foreigners, men and people aged from 50 to 69. The proportion of newly diagnosed or uncontrolled disease exceeded 40% of participants for both hypertension and hypercholesterolemia (7% for diabetes). Adherence rate to counselling was 99.4%. CONCLUSIONS: The MHC was effective in attracting hard-to-reach groups and individuals who may have otherwise gone undiagnosed. MHCs can play a complementary role also in universal coverage health systems, raising self-awareness of unreached population and making access to primary health care easier.

Risk factors for mortality among neonates admitted to a special care unit in a low-resource setting.

BACKGROUND: Although under-5 mortality has decreased in the last two decades, neonatal mortality remains a global health challenge. Despite achieving notable progress, Ethiopia has still one of the highest neonatal mortality rates worldwide. We aimed to assess the risk factors for mortality among neonates admitted to a special care unit in a referral hospital in rural Ethiopia. METHODS: This was a retrospective observational study including all 4182 neonates admitted to the special care unit of the St. Luke Wolisso Hospital (Ethiopia) from January 2014 to December 2017. Data were retrieved from hospital charts and entered in an anonymized dataset. A logistic regression model was applied to identify predictors of mortality and effect sizes were expressed as odds ratios with 95% confidence intervals. RESULTS: Proportion of deaths was 17% (709/4182 neonates). Neonates referred from other health facilities or home (odds ratio 1.52, 95% confidence interval 1.21 to 1.91), moderate hypothermia at admission (odds ratio 1.53, 95% confidence interval 1.09 to 2.15) and diagnosis of late-onset sepsis (odds ratio 1.63, 95% confidence interval 1.12 to 2.36), low birthweight (odds ratio 2.48, 95% confidence interval 2.00 to 3.09), very low birthweight (odds ratio 11.71, 95% confidence interval 8.63 to 15.94), extremely low birthweight (odds ratio 76.04, 95% confidence interval 28.54 to 263.82), intrapartum-related complications (odds ratio 4.69, 95% confidence interval 3.55 to 6.20), meconium aspiration syndrome (odds ratio 2.34, 95% confidence interval 1.15 to 4.43), respiratory distress (odds ratio 2.25, 95% confidence interval 1.72 to 2.95), other infections (odds ratio 1.92, 95% confidence interval 1.31 to 2.81) or malformations (odds ratio 2.32, 95% confidence interval 1.49 to 3.57) were associated with increased mortality. Being admitted in 2017 vs. 2014 (odds ratio 0.71, 95% confidence interval 0.52 to 0.97), and older age at admission (odds ratio 0.95, 95% confidence interval 0.93 to 0.97) were associated with decreased likelihood of mortality. CONCLUSIONS: The majority of neonatal deaths was associated with preventable and treatable conditions. Education on neonatal resuscitation and postnatal management, and the introduction of an on-call doctor for high-risk deliveries might have contributed to the reduction in neonatal mortality over time.

Impact of temperature change from admission to day one on neonatal mortality in a low-resource setting.

BACKGROUND: Thermal control after birth is an essential part of neonatal care. However, the relationship between neonatal temperature at and after admission is unknown. This study aimed to evaluate the change between neonatal temperature at admission and at day 1, and its impact on mortality. METHODS: Retrospective observational study at the Beira Central Hospital, Mozambique. Axillary temperatures were recorded at admission and at day 1 in 1,226 neonates who were admitted to the Special Care Unit between January 1 and December 31, 2017. The relationship between mortality rate and temperature change was evaluated with a matrix plot and a forest plot (obtained from a logistic regression model as odds ratios with 95% confidence intervals). RESULTS: Normothermia was found in 415 neonates (33.8%) at admission and in 638 neonates (52.0%) at day 1. Mortality rate was highest in (i) neonates who remained in severe/moderate hypothermia (74%), (ii) neonates who rewarmed from hypothermia (40-55%), and (iii) neonates who chilled to severe/moderate hypothermia (38-43%). Multivariable analysis confirmed that temperature change from admission to day 1 was an independent predictor of mortality (p < 0.0001). CONCLUSIONS: In a low-resource setting, one out of three neonates was found hypothermic at day 1 irrespectively of admission temperature. Relevant thermal deviations occurred in a high proportion of newborns with normothermia at admission. Being cold at admission and becoming cold or hyperthermic at day 1 were associated with increased likelihood of mortality. Appropriate actions to prevent both hypothermia and hyperthermia represent both a challenge and a priority during postnatal period.

A simplified diagnostic work-up for the detection of gestational diabetes mellitus in low resources settings: achievements and challenges.

PURPOSE: Modern strategies for the screening and diagnosis of Gestational Diabetes Mellitus (GDM) rely on universal Oral Glucose Tolerance Test (OGTT). However, they are unsustainable in low-income countries. In this study, we aimed at assessing the feasibility of a simplified diagnostic policy. METHODS: The study took place in an urban referral hospital in Freetown, Sierra Leone. During an 11-month period, pregnant women were offered capillary blood test for glucose assessment. They could be screened at any time during pregnancy. GDM was diagnosed if fasting glucose was ≥ 92 mg/dl or if the OGTT was positive. The latter was prescribed only to women presenting after 24 weeks' gestation with at least one risk factor for GDM and fasting capillary glucose between 85 and 91 mg/dl. A definitive diagnosis required confirmation to this aim, women with values above the thresholds were invited to refer the next working day for repeating the test after fasting overnight. RESULTS: Overall, 7827 women were referred for screening, of whom 6872 (87%) underwent at least one capillary glucose assessment. However, 895 of those who had a positive test did not return for confirmation. Overall, a definite assessment could be done in 5799 subjects corresponding to 76% (95% CI 75-77%) of those eligible. GDM was diagnosed in 128 women (1.9%, 95% CI 1.6-2.2%). Based on an expected confirmation rate of 22% (calculated from those who referred for confirmation) in the 895 women who did not come back, one could infer that GDM would have been diagnosed in additional 197 women, raising the prevalence to 4.7% (95% CI 4.2-5.3%). CONCLUSION: Three quarters of subjects could be assessed with our approach. Data also suggest that GDM is not rare even if identification of affected cases remains challenging.
