Background: In-hospital mortality is high in low-income countries. Currently, little is known in Cameroon concerning the characteristics of patients who die in cardiology units. Our objectives were to determine the in-hospital mortality rate;describe the general characteristics of death patients, and factors associated with mortality. Material and Methods: We conducted a retrospective cross-sectional study by reviewing the medical records of all patients admitted to the cardiology unit of the Yaoundé Central Hospital (CHY) between January 2018 andJanuary 2019. The files of all death patients were studied for socio-demographical, clinical and therapeutical variables. Bivariate analysis was conducted to order to check the association between independents variables and time of death. A p-value 0.05 was considered statistically significant. Results: A total number of 860 patients were admitted in the cardiology unit of CHY during the study period. Amongst the 860 patients admitted 78 had a fatal outcome, hence, an in-hospital mortality rate of 9.06%. The male gender was predominant amongst the deceased patients (n = 45). The mean age at death was 69 ± 15.19 years. The median time before death was 6 days and they ranged between 1 to 25 days. Hypertension was the most frequent comorbidity (65.4%). Stroke was the principal cause of admission (40.3%), whereas the main presenting complaint was dyspnea (26.9%). Before being a

Introduction: Anthropometry applied to newborns is a reliable indicator of the quality of fetal growth. The latter is influenced by genetic, racial and nutritional factors varying from one population to another, explaining why a standard cannot be applied to all populations. Research question: should the Caucasian frame of reference be dogmatically applied in our African context? Multicenter studies are therefore necessary;hence the interest of this work, the main objective of which was to describe the anthropometric profile of full-term newborns in the city of Douala. Methodology: We carried out a cross-sectional study with an analytical aim and prospective data collection in the maternity wards of the Douala General Hospital, Laquintinie Hospital, District hospitals of Deido, Nylon and Bonassama over a period of 4 months (January to April 2020). We were interested in any newborn, born alive, vaginally or by cesarean section, seen in the first 24 hours from a full-term single-fetal pregnancy whose mother had given consent. We excluded newborns whose term was unclear and those with congenital malformations or signs of embryo-foetopathy. Data collection was done using structured and pre-tested survey sheets. The study variables were obstetric and anthropometric. Statistical analyzes were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables, the percentages with a significance threshold P value Results: During the study period, 305 full-term newborns were included, divided into 172 boys and 133 girls. The average anthropometric parameters of the full-term newborn in the city of Douala were: average weight: 3305 grams, average height: 49.8 centimeters, average head circumference: 34.6 centimeters, average upper arm circumference: 11.3 centimeters, circumference average thoracic: 32.8 centimeters. The percentile distribution showed a 10th percentile at 2656 grams and a 90th

Introduction: Spontaneous abortion of the second trimester is an interruption of pregnancy with complete expulsion or not of the product of conception between 15 and 28 weeks of pregnancy without any maneuvers. The objective of our study was to determine the factors associated with second trimester spontaneous abortions at Laquintinie Hospital in Douala. Methodology for this purpose: We conducted a case-control study from January to May 2019 on pregnant women who may or may not have had spontaneous second trimester abortions. Results: In total we recorded 1609 pregnancies and recruited 184 patients, including 46 cases and 138 controls;which gave a frequency of spontaneous abortion in the second trimester of pregnancy of 2.85%. A correlative analysis showed that spontaneous abortions in the second trimester were associated with housewife status (OR = 2.89;CI = 1.21 - 6.79;p = 0.010), gestation > 5 (OR = 4.09;CI = 1.02 - 17.66;p = 0.040), multiparity (OR = 3.81;CI = 1.59 - 9.16;p = 0.002), history of endouterine maneuvers (OR = 5.64;CI = 2.43 - 13 .03;p = 0.000), malaria in pregnancy (OR = 3.99;CI = 1.1 - 14.76;p = 0.030), incompleteness on the second trimester ultrasound (OR = 2.37;CI = 1.18 - 4.70;p = 0.010), jolts when traveling (OR = 46.04;CI = 17.29 - 123.66;p = 0.000), long car journeys (OR = 7.05;CI = 1.99 - 27.77;p = 0.000). After logistic regression eliminating the confounding factors, only the following were associated with abortions: Multiparity (OR = 13.90;CI = 2.96 - 65.18;p = 0.000), endo uterine maneuvers (OR = 3.69;CI = 1. 01 - 13.44;p = 0.047), jolts when traveling (OR = 72.63;CI = 19.47 - 270.96;p = 0.000), long car journeys (OR = 15.41;CI = 2.7 - 85, 95;p = 0.000). Conclusion: Our study reveals that a set of factors contribute to the occurrence of spontaneous abortions in the second trimester of pregnancy in our context.

Introduction: Pregnancy as much as childbirth constitutes a risky situation, potentially fraught with sometimes dramatic complications: maternal death. Objective: We conducted this study with the aim of establishing the profile of those giving birth in our context with the aim to anticipate operationally in the future on morbidity but more on maternal deaths. Methodology: We conducted, using a structured questionnaire, a prospective descriptive study in representative maternity wards in the city of Douala;the study variables were socio-economic, anthropometric, obstetrical and clinical. Statistical analyses were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables and the percentages. Results: We recruited 305 births for our study. The average age of our births was 28.7 years ± 6.1 with an average height of 161.6 cm ± 5.06;an average body mass index at the start of pregnancy of 28.0 kilograms/square meter and 31.3 kilograms/square meter at delivery;the average weight gain was 8.4 g ± 5.37;an average gestation of 2.84±1.90;an average parity of 2.2 ± 2.1 with an average birth interval of 27.7 months ± 23.7. The average gestational age was 39.2 weeks ± 1.21 with pregnancy pathology dominated by malaria;85.9% began their prenatal follow-up before the 14th week of amenorrhea. Conclusion: The profile of childbirth in urban Cameroon does not seem potentially dystocic compared to that of the same regional and racial area.

Introduction: Low birth weight (LBW) is defined by the World Health Organization (WHO) as a birth weight strictly below 2500 g, whatever the term of pregnancy. It constitutes a major public health problem, both in developed and developing countries, due to its magnitude and its strong association with infant morbidity and mortality. Main objective was to study the factors associated with the occurrence of small-for-gestational-age newborns in Douala. Methodology: We carried out a cross-sectional analytical study with prospective data collection using a technical pretested sheet in the maternity wards of the Douala General Hospital, the Laquintinie Hospital, and the District hospitals of Deido, Nylon and Bonassama over a period of 4 months (January to April 2020). We were interested in any newborn, born alive, vaginally or by cesarean section, of low weight, seen in the first 24 hours from a full-term single-fetal pregnancy whose mother had given her consent. Our sampling was consecutive and non-exhaustive. We excluded newborns whose term was unclear and those with congenital malformations or signs of embryo-foetopathy. Data collection was done using survey sheets. Statistical analyzes were carried out with CS Pro 7.3 and SPSS version 25.0 software. The Student, Chi-square and Fischer tests were used to compare the means of the variables, the percentages with a significance threshold P value Results: During the study period, 305 full-term newborns were included, divided into 172 boys and 133 girls. The percentage of small-for-gestational-age newborns was 9.8%;after multivariate analysis by logistic regression to eliminate confounding factors, we found maternal factors associated with small for gestational age newborns;maternal age less than 20 years, primiparity, gestational age (37 - 38), a delay in prenatal visits greater than 14 weeks, anemia in pregnancy, positive toxoplasmosis serology in pregnancy, a body mass index of Conclusion: Our study revealed the potenti

Introduction: Pediatric nursing cares are among the most important care needed referring to the category of patients. A gap of the best practice in Pediatric Nursing Care (PNC) had been publically a major problem of health and raises the rate of morbidity and mortality. The lack of nursing guidelines, low level of studies, experience at work and low economic status of Health Care Facilities (HCFs) were the main problems assessed in these three HCFs (HUCK, VNC and MHK) in this study. The purpose of this study is to assess the knowledge of nurses during their practices in Pediatric Wards of HCFs and to provide a better contribution. Method: A descriptive study design was used in this study during the period of one month. 43, 25 and 30 nurses were selected among 98 nurses by using Dilman formula. A questionnaire with 5 parameters was distributed. Data were typed using Microsoft ward and analyzed using Statistical Package for Social Scientists version 16 software (SPSS). Results: The current study found that the majority of nurses don’t know to make the best nursing diagnosis neither the factors related to the implementation of EBP in PNC. The nurses have shown different barriers often met during their practices. The all process of nursing diagnosis was not recognized with the average of 97.6% of nurses. Conclusion: Even if the nurses have some experience at work they express their weakness based on low level of study, lack of knowledge and trained professionals on work and the pediatric nursing guidelines.

From a total of 80 fertile eggs incubated naturally by female ducks, healthy sexed ducklings (n = 64, 32 males and 32 females ducklings) were randomly selected and allotted to four dietary treatments with four replicates, in a completely randomized design in order to evaluate the effect of varying levels of palm kernel meal (PKM) on performance of ducklings. The dietary treatments comprised R0-control ration, R50-50% PKM replacement, R75-75% PKM re-placement and R100-100% PKM replacement of soyabean meal. The main results revealed that the apparent digestive coefficients of dry matter (81.12%), organic matter (83.98%) and NDF (81.10%) were higher with the ration in which 50% (R50-50% PKM replacement of soyabean meal) of soybean was replaced by palm kernel meal. The highest feed intake in male was recorded with the ration containing 75% (R75-75% PKM replacement of soyabean meal) of palm kernel. This same ration (R75-75% PKM replacement of soyabean meal) equally induced the highest live weight and weight gain in females. The experimental design and arrangement is a 2 × 4 factorial arrangement with two sexes and four levels of PKM. In males, the control ration without palm kernel meal induced the highest live weight and highest cumulative weight gain. The lowest feed conversion ratio (p 0.05) affected by the incorporation of palm kernel meal into the diet. Urea serum content tends to decrease with the increasing level of palm kernel meal in feed. In conclusion, soybean meal can advantageously be repla

Nutrition is the main factor determining the potential of farmed fish to exhibit their growth capacity as a function of the protein content and certain additives contained in their diet. Thus, the present study was conducted to assess dietary supplementation effects of ginger and garlic as feed additives on growth, feed utilization and whole-body composition in Clarias gariepinus fry. Following a 24 h fasting, 525 fry weighing 1.2 ± 0.01 g were randomly divided in triplicate into five treatments of 105 fish each and fed for 56 days. In treatment T0, fry was fed with control basal diet, in treatments T1 and T2, fry was fed with basal diet containing 1% and 2% ginger, while in treatments T3 and T4, fry was fed on basal diet supplemented with 1% and 2% garlic. Fish were fed at the rate of 10% of their body weight and every 14 days, intermediate fish sampling was done during which fry per treatment was counted, measurements taken on a representati
