RESUMEN

Background: Although vitamin D deficiency has been studied in various populations, there are few data on its prevalence and associated factors among Moroccan women. Aim: To determine the prevalence of vitamin D deficiency and investigate its association with body mass index (BMI), waist circumference, and serum concentrations of parathyroid hormone, calcium, and phosphorus in a sample of Moroccan adult women. Methods: This is a cross-sectional study conducted at Mohammed V Military Hospital of Instruction, Rabat. Anthropometric measurements and biochemical analyses were performed using standard procedures Results: A total of 714 women aged 18-65 years participated in this study. The overall prevalence of vitamin D deficiency was 74.4%. Approximately 24% and 51% of women had severe and moderate vitamin D deficiency, respectively. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were inversely correlated with BMI in vitamin D-deficient subjects (P = 0.036) and with parathyroid hormone 1-84 (PTH1-84) levels in the study sample (P = 0.010). PTH1-84 concentrations were greater among overweight/obese individuals compared to their non-overweight peers (P = 0.001) and tended to be higher among vitamin D-deficient women than vitamin D-sufficient women (P = 0.053). Conclusion: This study showed a very high prevalence of vitamin D deficiency in this sample of Moroccan women. Lower serum 25(OH)D levels were associated with increased BMI in vitamin D-deficient women and with elevated PTH1-84 levels among the study sample. Although these findings come from a convenience sample of women that attended a nutrition clinic, they underscore the urgent need to develop public health interventions to improve women's vitamin D status.

RESUMEN

BACKGROUND: Available data suggest that polyphenols from tea can inhibit iron absorption from ferric sodium EDTA (NaFeEDTA), but previous studies were done in small groups of mostly nonanemic adults. Morocco recently introduced national wheat flour fortification with NaFeEDTA, but tea is the national beverage and is consumed with most meals. OBJECTIVES: Our objective was to quantify bioavailability of iron from NaFeEDTA when added to a wheat flour-based meal in both nonanemic women and women with iron deficiency anemia (IDA), when consumed with and without traditional Moroccan green tea. METHODS: We recruited 2 groups of healthy Moroccan women (n = 46): women with IDA (n = 25; hemoglobin <12 g/dL,  serum ferritin <15 µg/L) and nonanemic women (n = 21). Each group received in random order 2 standardized test meals containing 6 mg Fe as isotopically labeled NaFeEDTA and either 300 mL of tea or water. Fractional iron absorption (FIA) was measured by the erythrocyte incorporation of stable iron isotopes after 14 d. We performed linear mixed-model analysis and post hoc sample t tests to assess the effects of group and tea on FIA. RESULTS: The polyphenol content of the tea serving was 492 mg. Tea consumption reduced iron absorption from NaFeEDTA by >85% in both IDA and nonanemic women. There were group (P < 0.001) and tea (P < 0.001) effects on FIA, but no group by tea interaction (P = 0.312). Median (IQR) FIA (%) in women with IDA from test meals consumed without and with tea was 36.7 (24.2-39.8) and 4.1 (2.8-6.1), respectively (P < 0.001). Median (IQR) FIA (%) in nonanemic women from test meals consumed without and with tea was 16.7 (9.2-24.2) and 1.4 (0.8-2.9), respectively (P < 0.001). CONCLUSIONS: FIA from wheat flour-based meals without and with tea was ∼2-fold higher in women with IDA than in nonanemic women. Providing fortificant iron as NaFeEDTA cannot overcome the inhibition of tea polyphenols on iron absorption, even in IDA, where iron absorption is strongly upregulated. This trial was registered at www.clinicaltrials.gov as NCT02175888.

RESUMEN

BACKGROUND: Babies born early and/or small for gestational age in Low and Middle-income countries (LMICs) contribute substantially to global neonatal and infant mortality. Tracking this metric is critical at a population level for informed policy, advocacy, resources allocation and program evaluation and at an individual level for targeted care. Early prenatal ultrasound examination is not available in these settings, gestational age (GA) is estimated using new-born assessment, last menstrual period (LMP) recalls and birth weight, which are unreliable. Algorithms in developed settings, using metabolic screen data, provided GA estimates within 1-2 weeks of ultrasonography-based GA. We sought to leverage machine learning algorithms to improve accuracy and applicability of this approach to LMICs settings. METHODS: This study uses data from AMANHI-ACT, a prospective pregnancy cohorts in Asia and Africa where early pregnancy ultrasonography estimated GA and birth weight are available and metabolite screening data in a subset of 1318 new-borns were also available. We utilized this opportunity to develop machine learning (ML) algorithms. Random Forest Regressor was used where data was randomly split into model-building and model-testing dataset. Mean absolute error (MAE) and root mean square error (RMSE) were used to evaluate performance. Bootstrap procedures were used to estimate confidence intervals (CI) for RMSE and MAE. For pre-term birth identification ROC analysis with bootstrap and exact estimation of CI for area under curve (AUC) were performed. RESULTS: Overall model estimated GA had MAE of 5.2 days (95% CI 4.6-6.8), which was similar to performance in SGA, MAE 5.3 days (95% CI 4.6-6.2). GA was correctly estimated to within 1 week for 85.21% (95% CI 72.31-94.65). For preterm birth classification, AUC in ROC analysis was 98.1% (95% CI 96.0-99.0; p < 0.001). This model performed better than Iowa regression, AUC Difference 14.4% (95% CI 5-23.7; p = 0.002). CONCLUSIONS: Machine learning algorithms and models applied to metabolomic gestational age dating offer a ladder of opportunity for providing accurate population-level gestational age estimates in LMICs settings. These findings also point to an opportunity for investigation of region-specific models, more focused feasible analyte models, and broad untargeted metabolome investigation.

RESUMEN

Hepatic hepcidin synthesis is stimulated by inflammation but inhibited during iron deficiency anemia (IDA). In humans, the relative strength of these opposing signals on serum hepcidin and the net effect on iron absorption and systemic iron recycling is uncertain. In this prospective, 45-day study, in young women (n=46; age 18-49 years) with or without IDA, we compared iron and inflammation markers, serum hepcidin and erythrocyte iron incorporation from 57Fe-labeled test meals, before and 8, 24 and 36 hours (h) after influenza/DPT vaccination as an acute inflammatory stimulus. Compared to baseline, at 24-36 h after vaccination: 1) interleukin-6 increased 2-3-fold in both groups (P<0.001); 2) serum hepcidin increased >2-fold in the non-anemic group (P<0.001), but did not significantly change in the IDA group; 3) serum iron decreased in the non-anemic group (P<0.05) but did not change in the IDA group; and 4) erythrocyte iron incorporation did not change in either of the two groups, but was approximately 2-fold higher in the IDA group both before and after vaccination (P<0.001). In this study, mild acute inflammation did not increase serum hepcidin in women with IDA, suggesting low iron status and erythropoietic drive offset the inflammatory stimulus on hepcidin expression. In non-anemic women, inflammation increased serum hepcidin and produced mild hypoferremia, but did not reduce dietary iron absorption, suggesting iron-recycling macrophages are more sensitive than the enterocyte to high serum hepcidin during inflammation. The study was registered as a prospective observational trial at clinicaltrials.gov identifier: 02175888 The study was funded by the International Atomic Energy Agency.

RESUMEN

BACKGROUND: Morocco is facing a growing prevalence of diabetes and according to latest figures of the World Health Organization, already 12.4% of the population are affected. A similar prevalence has been reported for gestational diabetes (GDM) and although it is not yet high on the national agenda, immediate and long-term complications threaten the health of mothers and future generations. A situational analysis on GDM conducted in 2015 revealed difficulties in access to screening and delays in receiving appropriate care. This implementation study has as objective to evaluate a decentralized GDM detection and management approach through the primary level of care and assess its potential for scaling up. METHODS: We will conduct a hybrid effectiveness-implementation research using a cluster randomized controlled trial design in two districts of Morocco. Using the health center as unit of randomization we randomly selected 20 health centers with 10 serving as intervention and 10 as control facilities. In the intervention arm, providers will screen pregnant women attending antenatal care for GDM by capillary glucose testing during antenatal care. Women tested positive will receive nutritional counselling and will be followed up through the health center. In the control facilities, screening and initial management of GDM will follow standard practice. Primary outcome will be birthweight with weight gain during pregnancy, average glucose levels and pregnancy outcomes including mode of delivery, presence or absence of obstetric or newborn complications and the prevalence of GDM at health center level as secondary outcomes. Furthermore we will assess the quality of life /care experienced by the women in both arms. Qualitative methods will be applied to evaluate the feasibility of the intervention at primary level and its adoption by the health care providers. DISCUSSION: In Morocco, gestational diabetes screening and its initial management is fragmented and coupled with difficulties in access and treatment delays. Implementation of a strategy that enables detection, management and follow-up of affected women at primary health care level is expected to positively impact on access to care and medical outcomes. TRIAL REGISTRATION: The trial has been registered on clininicaltrials.gov ; identifier NCT02979756 ; retrospectively registered 22 November 2016.

RESUMEN

BACKGROUND: Several pathogenesis and genetic factors influence predisposition to antituberculosis drug-induced hepatotoxicity (ATDH) especially for isoniazid (INH). However, the major susceptibility genes for ATDH are N-acetyltransferase 2 (NAT2) and cytochrome P450 2E1 (CYP2E1). NAT2 gene determines the individual's acetylator status (fast, intermediate or slow) to metabolize drugs and xenobiotics, while CYP2E1 c1/c1 genotype carriers had an increased risk of ATDH. Polymorphisms of the NAT2 and CYP2E1 genes vary remarkably among the populations of different ethnic origins. The aim of this study was to determine, for the first time, the frequency of slow acetylators in Moroccan population by genotyping of NAT2 gene variants and determining the genotype c1/c1 for CYP2E1 gene, in order to predict adverse effects of Tuberculosis treatment, particularly hepatotoxicity. RESULTS: The frequencies of specific NAT2 alleles were 53%, 25%, 2% and 4% for NAT2*5, NAT2*6, NAT2*7 and NAT2*14 respectively among 163 Moroccan studied group. Genotyping of CYP2E1 gene, by real-time polymerase chain reaction using TaqMan probes, revealed frequencies of 98.5% for c1/c1 and 1.5% for c1/c2 among 130 Moroccan studied group. CONCLUSION: The most prevalent genotypes of NAT2 gene in Moroccans are those which encode slow acetylation phenotype (72.39%), leading to a high risk of ATDH. Most Moroccans are homozygous for c1 allele of CYP2E1 gene which aggravates hepatotoxicity in slow acetylators. This genetic background should be taken into account in determining the minimum dose of INH needed to treat Moroccan TB patients, in order to decrease adverse effects.

RESUMEN

The initial colonization of the intestine represents one of the most profound immunological exposures faced by the newborn. During the first three years of life, the intestinal microbial composition undergoes significant changes. At birth, the digestive tract is rapidly colonized by microorganisms of maternal and environmental origins. Microbiota's composition is influenced by various factors, including the mode of delivery, gestational age, type of feeding, and medication use. Through the current study, we specifically focused on elucidating the dynamics of gut microbiota colonization within the first three weeks of life of infants, shedding light on this critical phase of development. A prospective cohort study involving 29 preterm infants was conducted from January to September 2021 at the National Reference Center for Neonatology and Nutrition, in collaboration with the research laboratory of Children's Hospital at the University Hospital Center Ibn Sina in Rabat. Stool samples were collected from each infant's diapers into a sterile tube and send for laboratory analysis. A total of 203 stool samples were collected. For each newborn, one stool sample was obtained within the first 48 h after birth, followed by two samples per week over a period of three weeks. The microbial compositions of these samples were analyzed using real-time polymerase chain reaction.

RESUMEN

BACKGROUND: The concept of Near Miss, has been used in the field of obstetrics as a tool for assessing and improving the quality of care. However, there is no standardized definition or international criteria for identifying neonatal near misses. The current review aims to investigate the development of the neonatal near miss concept based on the results of studies conducted so far on neonatal near misses and their identification criteria. RESULTS: Sixty-two articles were retrieved by the electronic search, and after examination of different abstracts and reading of full texts, 17 articles were considered eligible meeting our inclusion criteria. All selected articles varied in terms of concept definition and criteria used. Neonatal Near Miss was defined as any newborn with pragmatic and/or management criteria who survived the first 27 days of life. All studies reviewed showed a Neonatal Near Miss rate that was 2.6 to 10 times higher than the neonatal mortality rate. CONCLUSIONS: Neonatal Near Miss is a new concept that is currently being debated. There is a need for universal consensus on the definition and its identification criteria. Further efforts are needed to standardize the definition of this concept, including the development of criteria that can be assessed in a neonatal care setting. This is to improve the quality of neonatal care in every setting, regardless of the local level.

RESUMEN

BACKGROUND: The concept of near-miss neonatal (NMN) is a potentially useful approach in assessing the quality of newborn care. However, data collected on the status of NMN cases in Morocco is scarce. OBJECTIVE: The objective of this study is to determine the prevalence of NMN cases among live births at the University Hospital of Rabat, Morocco. MATERIALS AND METHODS: An observational cross-sectional study was conducted on 2676 newborns born at the University Hospital of Rabat, Morocco, and admitted to the National Reference Center of Neonatology and Nutrition (NRCN) from January 1 to December 31, 2021. The main inclusion criteria were the pragmatic and/or management markers of the definition of NMN. Data were extracted using a structured, pre-tested checklist, entered into EpiData, and exported to Statistical Software for the Social Sciences (SPSS) version 23 (IBM Corp., Armonk, NY), and descriptive statistics were performed. RESULTS: Among the 2676 selected live births, 2367 were NMN cases (88.5%; 95% CI: 88.3-90.7). More than half of new mothers (57.5%) were referrals, 59.9% of women were multiparous, and 78.5% had under four prenatal care consultations. Obstetric problems affected 373 of the women during pregnancy. A pragmatic criterion was met in 43.6% of NMN situations. Among the management criteria, the use of intravenous antibiotics was the most common factor at 56.0%. CONCLUSIONS: This study revealed a high prevalence of NMN. Therefore, concerted efforts are needed to improve maternal health care services, including early identification of complications and appropriate management.

RESUMEN

Introduction: awareness and knowledge of toxoplasmosis are particularly important, as an intervention point for the management of the disease. The aim of this study was to evaluate the awareness and knowledge regarding toxoplasmosis in a sample of postpartum Moroccan women. Methods: this was a cross-sectional descriptive survey carried out among 320 parturient at the National Reference Center for Neonatology and Nutrition at the Children's Hospital of Rabat. Results: of 320 parturient women responding to the survey, 227 (71%) had never heard about toxoplasmosis. While 18.1% of parturient stated knowing the transmission routes for toxoplasmosis. Regarding the transmission route, 53 (16.6%) women pointed at a domestic cat and 31 (9.7%) at eating raw or undercooked meat. Out of all participants, 60 (18.8%) women said they had received prevention advice during their pregnancy. The great majority (90%) of participants were unaware of the severity of the congenital infection. None of the participants showed a high level of knowledge about transmission routes, measures of prevention, and severity of CT. Conclusion: according to our survey, we observed that the majority of participants had never heard any information about toxoplasmosis. It is, therefore, necessary to educate women of childbearing age and pregnant women about the disease, especially concerning the transmission route and the prevention of infection and primary infection in non-immune women.

RESUMEN

Background: Population-based seroepidemiological surveys provide accurate estimates of disease burden. We compare the COVID-19 prevalence estimates from two serial serological surveys and the associated risk factors among women and children in a peri-urban area of Karachi, Pakistan. Methods: The AMANHI-COVID-19 study enrolled women and children between November 2020 and March 2021. Blood samples were collected from March to June 2021 (baseline) and September to December 2021 (follow-up) to test for anti-SARS-CoV-2 antibodies using ROCHE Elecsys®. Participants were visited or called weekly during the study for recording symptoms of COVID-19. We report the proportion of participants with anti-SARS-CoV-2 antibodies and symptoms in each survey and describe infection risk factors using step-wise binomial regression analysis. Results: The adjusted seroprevalence among women was 45.3% (95% confidence interval (CI) = 42.6-47.9) and 82.3% (95% CI = 79.9-84.4) at baseline and follow-up survey, respectively. Among children, it was 18.4% (95% CI = 16.1-20.7) and 57.4% (95% CI = 54.3-60.3) at baseline and follow-up, respectively. Of the women who were previously seronegative, 404 (74.4%) tested positive at the follow-up survey, as did 365 (50.4%) previously seronegative children. There was a high proportion of asymptomatic infection. At baseline, being poorest and lacking access to safe drinking water lowered the risk of infection for both women (risk ratio (RR) = 0.8, 95% CI = 0.7-0.9 and RR = 1.2, 95% CI = 1.1-1.4, respectively) and children (RR = 0.7, 95% CI = 0.5-1.0 and RR = 1.4, 95% CI = 1.0-1.8, respectively). At the follow-up survey, the risk of infection was lower for underweight women and children (RR = 0.4, 95% CI = 0.3-0.7 and RR = 0.7, 95% CI = 0.5-0.8, respectively) and for women in the 30-39 years age group and children who were 24-36 months of age (RR = 0.6, 95% CI = 0.4-0.9 and RR = 0.7, 95% CI = 0.5-0.9, respectively). In both surveys, paternal employment was an important predictor of seropositivity among children (RR = 0.7, 95% CI = 0.6-0.9 and RR = 0.8, 95% CI = 0.7-1.0, respectively). Conclusion: There was a high rate of seroconversion among women and children. Infection was generally mild. Parental education plays an important role in protection of children from COVID-19.

RESUMEN

Introduction: obesity and anemia remain global public health problems, having major negative effects on human health. We aimed to estimate the prevalence of anemia and investigate its association with overweight/obesity and excess body fat among Moroccan adolescents. Methods: a total of 292 adolescents aged 11-17 years were recruited. Body mass index (BMI) and waist circumference (WC) were determined using standardized equipment. Body fat mass was measured by bioelectrical impedance analysis. Hemoglobin concentration was measured by the HemoCue method. Results: the overall prevalence of anemia was 13.7%. Anemia was more common among overweight/obese participants (15.2%) compared to non-overweight participants (12.8%). Overweight/obese boys were more likely to experience anemia than their non-overweight peers (odds ratio (OR): 1.49; 95% confidence interval (95%CI): 0.51-4.41). Similarly, anemia likelihood was higher among individuals having excess body fat than those who do not have excess body fat, particularly among girls (OR: 1.64; 95%CI: 0.69-3.87). Excess body fat was also significantly associated with lower hemoglobin concentration in both the total sample and girls (P=0.014, and P=0.041, respectively). Overall, increased BMI, WC, fat mass, and percent body fat were associated with reduced hemoglobin concentrations. There was a significant negative correlation between hemoglobin concentration and BMI among anemic girls (P=0.023). Conclusion: elevated BMI and body fat level were associated with lower hemoglobin concentrations and anemia. Further studies are needed to delineate the basis of such associations, and if these findings are confirmed, the guidelines for screening for anemia may need to be modified to include overweight/obesity as a risk factor.

RESUMEN

Background: Knowledge of gestational age is critical for guiding preterm neonatal care. In the last decade, metabolic gestational dating approaches emerged in response to a global health need; because in most of the developing world, accurate antenatal gestational age estimates are not feasible. These methods initially developed in North America have now been externally validated in two studies in developing countries, however, require shipment of samples at sub-zero temperature. Methods: A subset of 330 pairs of heel prick dried blood spot samples were shipped on dry ice and in ambient temperature from field sites in Tanzania, Bangladesh and Pakistan to laboratory in Iowa (USA). We evaluated impact on recovery of analytes of shipment temperature, developed and evaluated models for predicting gestational age using a limited set of metabolic screening analytes after excluding 17 analytes that were impacted by shipment conditions of a total of 44 analytes. Results: With the machine learning model using all the analytes, samples shipped in dry ice yielded a Root Mean Square Error (RMSE) of 1.19 weeks compared to 1.58 weeks for samples shipped in ambient temperature. Out of the 44 screening analytes, recovery of 17 analytes was significantly different between the two shipment methods and these were excluded from further machine learning model development. The final model, restricted to stable analytes provided a RMSE of 1.24 (95% confidence interval (CI) = 1.10-1.37) weeks for samples shipped on dry ice and RMSE of 1.28 (95% CI = 1.15-1.39) for samples shipped at ambient temperature. Analysis for discriminating preterm births (gestational age <37 weeks), yielded an area under curve (AUC) of 0.76 (95% CI = 0.71-0.81) for samples shipped on dry ice and AUC of 0.73 (95% CI = 0.67-0.78) for samples shipped in ambient temperature. Conclusions: In this study, we demonstrate that machine learning algorithms developed using a sub-set of newborn screening analytes which are not sensitive to shipment at ambient temperature, can accurately provide estimates of gestational age comparable to those from published regression models from North America using all analytes. If validated in larger samples especially with more newborns <34 weeks, this technology could substantially facilitate implementation in LMICs.

RESUMEN

INTRODUCTION: anyone can develop posttraumatic stress disorder (PTSD) following a traumatic event; this disorder can develop comorbid PTSD disorders such as anxiety and depression, which could seriously interfere with the daily life of the adolescent who was to be the subject of our study by evaluating the prevalence of PTSD in public schools and also evaluating the impact of this disorder. METHODS: the survey was carried out during the period from March to June 2017. Participants were selected for a cross-sectional survey. Standardized questionnaires (life events checklist, CPTS-RI, STAIY and CDI) were used. The independent variables were investigated using binary logistic regression analyzes which were performed to investigate factors associated with PTSD. RESULTS: the number of students was 982 adolescents with an age of 12 to 17 years (14.98 ± 1.49) and the participation rate was 88.69% (n = 871). A high prevalence of PTSD was found with 19.3% (n = 168). The factors independently associated with PTSD included being a girl (adjusted odds ratio (AOR) =2.113, 95% C.I =1.015-4.399, p=0.046), having a middle school level (AOR =5.765, 95% C.I =2.262-14.692, p<0.0001), sleep interrupted (AOR =0.142, 95% C.I =0.027-0.745, p=0.021), guilt (AOR =27.378, 95% C.I =6.835-109.663, p<0.0001), difficulties of memory (AOR =0.157, 95% C.I = 0.071-0.346, p<0.0001), and difficulties of concentration (AOR =0.041, 95% C.I = 0.004-0.392, p=0.006). Among adolescents in school with PTSD, anxiety had 79.1% (n = 133) and depression had 51.1% (n = 86). CONCLUSION: the prevalence of PTSD and comorbid anxiety and depression was high among educated students. Factors associated with PTSD included being in college, being a girl, and having guilt. It is necessary to adapt suitable treatments immediately after a traumatic event or during the disease.

RESUMEN

Obesity is a real public health problem whose prevalence continues to increase throughout the world. It affects all age groups and does not spare pregnant women. This work aims to determine the prevalence of obesity and to study its association with maternal and neonatal characteristics and the morbidity profile of pregnancy. This is a descriptive and cross-sectional study carried out in the maternity ward of the prefectural hospital center called "Sidi Lahcen" in Témara, Morocco, over a 12-month period. Maternal and neonatal data are collected through a preestablished questionnaire, and anthropometric parameters were recorded. 390 participants, aged between 18 and 43 years, were included in this study, with a prevalence of overweight and obesity of 34.9% and 41%, respectively. Correlation results revealed that the prevalence of overweight and obesity was significantly elevated in women over 25 years (p < 0.001). The rate of caesarean section was four times higher in obese women compared to women of normal weight (53.8% versus 12.8%; p=0.018). The over-term was significantly high in the obese group compared to the nonobese group (33.8% versus 20.2%; p=0.013). A statistically significant positive correlation was found between gestational body mass index and newborn birth weight (r = 0.29; p < 0.001) as well as a high prevalence of macrosomia in newborns of comparatively obese women compared to newborns of nonobese women (17.6% versus 9.6%; p=0.041). The correlation analysis with the morbidity profile showed a significantly high preponderance of gestational diabetes, anemia, and toxemia of pregnancy in the obese group compared to the normal group (p < 0.001). This study clearly demonstrated that obesity during pregnancy is associated with higher risks of maternal and neonatal complications, the management of which places a burden on the health system as well as families. These data reinforce the need to improve antenatal care for the prevention of obesity and its preventable complications.

RESUMEN

BACKGROUND: Exclusive breastfeeding during the first six months of an infant's life is an important factor for their optimal growth and health. Breastfeeding also has maternal benefits and can assist with postpartum weight loss. As shown by previous studies, postpartum weight retention can contribute to obesity. OBJECTIVE: To quantify the human milk and evaluate the effect of breastfeeding on maternal weight loss during the 12 months postpartum. METHOD: This study included 70-mother-baby pairs. Infants' intake of human milk and water from other sources, as well as the body composition of the mothers, were measured at the 1st, 3rd, 6th, 9th and 12th month postpartum by using the deuterium oxide dose-to-mother technique. RESULTS: There was a significant change in the mothers' body composition between the first and twelfth months in exclusive breastfeeding women compared to not-exclusive ones. Similarly, the difference between the quantities of human milk intake was highly significant in exclusive breastfeeding women compared to women who were not exclusively breastfeeding. CONCLUSION: Our results showed that exclusive breastfeeding for twelve months has a significant effect on postpartum weight loss among Moroccan women and that it is an effective way to control overweight and obesity among lactating women.

RESUMEN

Point-of-care (POC) testing for Toxoplasma infection has the potential to revolutionize diagnosis and management of toxoplasmosis, especially in high-risk populations in areas with significant environmental contamination and poor health infrastructure precluding appropriate follow-up and preventing access to medical care. Toxoplasmosis is a significant public health challenge in Morocco, with a relatively heavy burden of infection and, to this point, minimal investment nationally to address this infection. Herein, we analyse the performance of a novel, low-cost rapid test using fingerstick-derived whole blood from 632 women (82 of whom were pregnant) from slums, educational centres, and from nomad groups across different geographical regions (i.e. oceanic, mountainous) of Morocco. The POC test was highly sensitive and specific from all settings. In the first group of 283 women, sera were tested by Platelia ELISA IgG and IgM along with fingerstick whole blood test. Then a matrix study with 349 women was performed in which fingerstick - POC test results and serum obtained by venipuncture contemporaneously were compared. These results show high POC test performance (Sensitivity: 96.4% [IC95 90.6-98.9%]; Specificity: 99.6% [IC95 97.3-99.9%]) and high prevalence of Toxoplasma infection among women living in rural and mountainous areas, and in urban areas with lower educational levels. The high performance of POC test confirms that it can reduce the need for venipuncture and clinical infrastructure in a low-resource setting. It can be used to efficiently perform seroprevalence determinations in large group settings across a range of demographics, and potentially expands healthcare access, thereby preventing human suffering.

RESUMEN

BACKGROUND: Globally, 15 million infants are born preterm and another 23.2 million infants are born small for gestational age (SGA). Determining burden of preterm and SGA births, is essential for effective planning, modification of health policies and targeting interventions for reducing these outcomes for which accurate estimation of gestational age (GA) is crucial. Early pregnancy ultrasound measurements, last menstrual period and post-natal neonatal examinations have proven to be not feasible or inaccurate. Proposed algorithms for GA estimation in western populations, based on routine new-born screening, though promising, lack validation in developing country settings. We evaluated the hypothesis that models developed in USA, also predicted GA in cohorts of South Asia (575) and Sub-Saharan Africa (736) with same precision. METHODS: Dried heel prick blood spots collected 24-72 hours after birth from 1311 new-borns, were analysed for standard metabolic screen. Regression algorithm based, GA estimates were computed from metabolic data and compared to first trimester ultrasound validated, GA estimates (gold standard). RESULTS: Overall Algorithm (metabolites + birthweight) estimated GA to within an average deviation of 1.5 weeks. The estimated GA was within the gold standard estimate by 1 and 2 weeks for 70.5% and 90.1% new-borns respectively. Inclusion of birthweight in the metabolites model improved discriminatory ability of this method, and showed promise in identifying preterm births. Receiver operating characteristic (ROC) curve analysis estimated an area under curve of 0.86 (conservative bootstrap 95% confidence interval (CI) = 0.83 to 0.89); P < 0.001) and Youden Index of 0.58 (95% CI = 0.51 to 0.64) with a corresponding sensitivity of 80.7% and specificity of 77.6%. CONCLUSION: Metabolic gestational age dating offers a novel means for accurate population-level gestational age estimates in LMIC settings and help preterm birth surveillance initiatives. Further research should focus on use of machine learning and newer analytic methods broader than conventional metabolic screen analytes, enabling incorporation of region-specific analytes and cord blood metabolic profiles models predicting gestational age accurately.

RESUMEN

BACKGROUND: We report the results of INICC surveillance study from 2013 to 2018, in 664 intensive care units (ICUs) in 133 cities, of 45 countries, from Latin-America, Europe, Africa, Eastern-Mediterranean, Southeast-Asia, and Western-Pacific. METHODS: Prospective data from patients hospitalized in ICUs were collected through INICC Surveillance Online System. CDC-NHSN definitions for device-associated healthcare-associated infection (DA-HAI) were applied. RESULTS: We collected data from 428,847 patients, for an aggregate of 2,815,402 bed-days, 1,468,216 central line (CL)-days, 1,053,330 mechanical ventilator (MV)-days, 1,740,776 urinary catheter (UC)-days. We found 7,785 CL-associated bloodstream infections (CLAB), 12,085 ventilator-associated events (VAE), and 5,509 UC-associated urinary tract infections (CAUTI). Pooled DA-HAI rates were 5.91% and 9.01 DA-HAIs/1,000 bed-days. Pooled CLAB rate was 5.30/1,000 CL-days; VAE rate was 11.47/1,000 MV-days, and CAUTI rate was 3.16/1,000 UC-days. P aeruginosa was non-susceptible (NS) to imipenem in 52.72% of cases; to colistin in 10.38%; to ceftazidime in 50%; to ciprofloxacin in 40.28%; and to amikacin in 34.05%. Klebsiella spp was NS to imipenem in 49.16%; to ceftazidime in 78.01%; to ciprofloxacin in 66.26%; and to amikacin in 42.45%. coagulase-negative Staphylococci and S aureus were NS to oxacillin in 91.44% and 56.03%, respectively. Enterococcus spp was NS to vancomycin in 42.31% of the cases. CONCLUSIONS: DA-HAI rates and bacterial resistance are high and continuous efforts are needed to reduce them.

RESUMEN

Our paper reports a case of hepatic angioma revealed by neonatal cholestasis, thing that has never been reported in the literature to our knowledge. A newborn boy of 25 days of life had cholestatic jaundice since his fifth day of life. During its health assessment, the angioscan detected the presence of multiple hepatic agiomas. The rest of the etiological report returned without any anomaly. Beta-blockers were started with a very good clinical and ultrasonographic evolution after 12 months of treatment.
