Low Birth Weight in Cameroon: Research and Analysis of Factors Associated with Their Occurrence in Douala Maternity Wards

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 potential determinants of low birth weight at term in the Cameroonian urban context and specifically in Douala.

Low Birth Weight and Intermittent Preventive Treatment of Malaria in Pregnant Women in Lomé (Togo) in 2021: A Cross-Sectional Study

Background: Since 2012, the World Health Organization has recommended intermittent preventive treatment with sulfadoxine-pyrimethamine (IPT-SP) to prevent malaria-related complications in pregnant women. Ten years following these recommendations, we conducted this study to estimate the coverage for three doses of IPT-SP (IPT3) as well as the prevalence of low birth weight (LBW), and its associated factors in Lomé (Togo) in 2021. Methods: A cross-sectional study was conducted between January and March 2021. An exhaustive recruitment of women and their newborns was carried out in the maternity wards of the Sylvanus Olympio University Hospital Center. Data from antenatal consultations and clinical data of the newborns were collected. Multivariate logistic regression was carried out to determine factors associated with LBW. Results: A total of 252 mother-child pairs were included in this study. Median age of the mothers was 27 years, IQR [24-31]. More than a third (35.3%) of the mothers were primigravida. IPT3 coverage was 66.7% and 14.7% of newborns had a LBW. The prevalence of LBW was 33.3% [23.3-43.4] in women who had received fewer than 3 doses of IPT-SP and 5.4% [2.0-8.8] in those who had received at least 3 doses of IPT-SP (p Conclusion: Ten years following recommendations of the WHO on IPT-SP, malaria prevention based on IPT-SP is not optimal among pregnant women in Lomé, and the proportion of LBW children remains high. Actions to strengthen the three-dose IPT-SP policy are needed to prevent malaria and its consequences among newborns in Togo.

Sociodemographic determinants associated with breastfeeding in term infants with low birth weight in Latin American countries

BACKGROUND A progressive decrease in exclusive breastfeeding(BF)is observed in Latin America and the Caribbean compared with global results.The possibility of being breastfed and continuing BF for>6 months is lower in low birth weight than in healthy-weight infants.AIM To identify factors associated with BF maintenance and promotion,with particular attention to low-and middle-income countries,by studying geographic,socioeconomic,and individual or neonatal health factors.METHODS A scoping review was conducted in 2018 using the conceptual model of social determinants of health published by the Commission on Equity and Health Inequalities in the United States.The extracted data with common characteristics were synthesized and categorized into two main themes:(1)Sociodemographic factors and proximal determinants involved in the initiation and maintenance of BF in low-birth-weight term infants in Latin America;and(2)individual characteristics related to the self-efficacy capacity for BF maintenance and adherence in low-birth-weight term infants.RESULTS This study identified maternal age,educational level,maternal economic capacity,social stratum,exposure to BF substitutes,access to BF information,and quality of health services as mediators for maintaining BF.CONCLUSION Individual self-efficacy factors that enable BF adherence in at-risk populations should be analyzed for better health outcomes.

Hypoglycaemia in screening oral glucose tolerance test in pregnancy with low birth weight fetus

Maternal hypoglycemia,a condition characterized by lower than normal blood glucose levels in pregnant women,has been increasingly associated with adverse pregnancy outcomes,including low birth weight(LBW)in neonates.LBW,defined as a birth weight of less than 2500 g,can result from various factors,including maternal nutrition,health status,and metabolic conditions like hypoglycemia.Maternal hypoglycemia may affect fetal growth by altering the supply of essential nutrients and oxygen to the fetus,leading to restricted fetal development and growth.This condition poses significant risks not only during pregnancy but also for the long-term health of the child,increasing the likelihood of developmental delays,health issues,and chronic conditions later in life.Research in this area has focused on understanding the mechanisms through which maternal hypoglycemia influences fetal development,with studies suggesting that alterations in placental blood flow and nutrient transport,as well as direct effects on fetal insulin levels and metabolism,may play a role.Given the potential impact of maternal hypoglycemia on neonatal health outcomes,early detection and management are crucial to minimize risks for LBW and its associated complications.Further investigations are needed to fully elucidate the complex interactions between maternal glucose levels and fetal growth,as well as to develop targeted interventions to support the health of both mother and child.Understanding these relationships is vital for improving prenatal care and outcomes for pregnancies complicated by hypoglycemia.

Acceptability of Kangaroo Mother Care (KMC) by Mothers with Low-Birth-Weight Babies at Arthur Davison Children’s Hospital, in Ndola, Zambia

Background: Kangaroo Mother Care is a simple safe method used to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care systems. Globally, complications due to low-birth-weight are the leading cause of neonatal mortality, resulting in an estimated 1 million deaths annually. Kangaroo Mother Care (KMC) is a low-cost method of care for low-birth-weight infants in areas with inadequate incubators and power outages with positive outcomes. Objectives: To assess factors influencing acceptability of Kangaroo Mother Care (KMC) in NICU at Arthur Davison Children’s Hospital in Ndola, Zambia. Methodology: A cross sectional quantitative analytical study design was used. The study was conducted at Arthur Davison Children’s Hospital (ADCH) in Ndola, Zambia. The purposive sampling method was used to select the study participants and a total of 129 mothers with Low Weight Babies A were selected to participate structured closed ended questionnaire was used to collect data from the participants using an interview. Data was analyzed using a Statistical Package for Social Scientists (SPSS) software version 26. Cross tabulations were done to determine association of variables using a Chi square (x2) test at 95% confidence interval and were assumptions where not met, fishers exact test was used. Multivariate binary logistic regression analysis was used to quantify the relationship between the dependent and independent variables. Results: Most of the respondents had male babies 77%, 69% of the babies weighed 1000 g - 1400 g, majority 79% had normal delivery, 71% of the respondents were multigravida and most of the respondents 79% were married. The study reviewed that 85% of those who attained secondary education accepted KMC, 74% of the respondents without monthly income accepted KMC, 80% of the respondents had positive attitude and accepted KMC. 82% of the respondents who had positive perception accepted KMC. Conclusion: Acceptance of Kangaroo Mother Care (KMC) among 75% of the mothers underscores its widespread favourability as a beneficial method for infant care.

Neurodevelopmental Outcomes of Extremely Premature Infants with Extremely Low and Very Low Birth Weight at Three Years of Age: A Retrospective Study

Introduction: The purpose of this retrospective study is to identify medical conditions impacting neurodevelopmental outcomes of extremely low birth weight and very low birth weight preterm infants at three years of age. Methods: Infants born in Banner Diamond Children’s University Medical Center, receiving services in the Newborn Intensive Care Unit, and attending Neonatal Developmental Follow-Up Clinic were identified. Participants received developmental assessment and follow-up from August 2012 through December 2018. Relevant clinical conditions during initial hospital stay and up to three years of age were obtained by reviewing medical and developmental records. Bayley Scales of Infant Toddler Development (Bayley III) was used to evaluate skill development at 6, 9, 12, 18, 24, 30, 36 months. Results: Data analysis did not reveal significant p-values;it did demonstrate that some predictor variables impact neurodevelopmental outcomes in cognitive, language and motor skill development. Conclusion: This retrospective study reports significant association between birth weight and low cognitive scores. Correlations were also found between gestational age and Total Language, and the longer an infant stayed in the NICU, the poorer the Total Language Scaled Scores at 8 to 12 months, 15 to 18 months, and 24 to 36 months. Birth weight was found to be the greatest predictor of poor motor scores.

Epidemioclinical Profile and Immediate Outcome of Low Birth Weight at the Reference Health Center in Commune VI of the District of Bamako, Mali

Introduction: Low birth weight is responsible for 9.1 million child deaths each year worldwide. It is the leading cause of perinatal and infant mortality. The objective of this work was to determine the epidemio-clinical profile as well as the future of low birth weight at the Reference Health Center of commune VI in the district of Bamako, Mali. Methods: Our study was descriptive and prospective over a year from April 1, 2018 to March 31, 2019. Data were taken from hospital records and newborn referral/evacuation forms. Data processing was performed using Epi Info software version 3.5.4 and Word. Results: The frequency of low birth weight was 34.94%. Multiparity accounted for 47.84%, sex ratio was 0.93, maternal arterial hypertension was present in 41.66%, genitourinary infection was in 58.37% and delivery was by low way in 86.12%. The majority of newborns had a gestational age between 28SA-33SA (56.52%) and a weight between 1501-1999 grams (47.36%). Mortality accounted for 18.66%. Conclusion: Low birth weight is common in our settings with modifiable risk factors. Practitioners must play on them to minimize its importance.

Epidemiology of Low Birth Weight in the Lake Areas of Cotonou (Benin Republic)

Introduction: Low birth weight is a significant public health problem worldwide, particularly in low-and-middle-income countries. This study aimed to investigate the epidemiology of low birth weight in the lake areas of Cotonou. Methods: A cross-sectional analytical study included 931 records of women who gave birth in 2022 in the Cotonou 1-4 health zone. Completed maternity records were included in this study, except for premature births and congenital malformations. Birth weight was the dependent variable. Sociodemographic, obstetrical, preventive care and child-related data were collected using a digitized form. These data were analyzed using SPSS software to determine the prevalence and factors associated with low birth weight using multiple logistic regression analysis. Results: The prevalence of low birth weight was 16.30%. Factors related to this prevalence were non-use of mosquito nets during pregnancy (OR = 2.72;CI: 1.275 - 5.805), twin pregnancy (OR = 9.97;CI: 3.869 - 25.696), previous abortion (OR = 1.61;CI: 1.034 - 2.515), low number of pregnancy (OR = 3.97;CI: 1.276 - 12.393), trimester of first antenatal visit (OR = 3.47;CI: 1.821 - 6.638) and birth size less than 45 cm (OR = 5.98;CI: 2.965 - 12.083). Conclusion: The prevalence obtained from this study justifies the need to support pregnant women in this health zone. It is, therefore, essential to strengthen communication and health promotion strategies for women before, during, and after pregnancy.

Maternal risk factors for low birth weight for term births in a developed region in China:a hospital-based study of 55,633 pregnancies

Low birth weight （LBW） is an important risk factor for neonatal and infant mortality and morbidity in adults.. How- ever, no large scale study on the prevalence of LBW and related maternal risk factors in China has been published. To explore the effects of maternal factors on LBW for term birth in China, we conducted a hospital-based retrospective study of 55, 633 Chinese pregnancy cases between 2001 and 2008. Maternal sociodemographic data, history of infer- tility and contraceptive use were obtained. Their medical status and diseases during pre-pregnancy were examined by physical examination at the first antenatal care visit. Maternal medical status before childbirth and pregnancy outcomes, including body weight, infant gender, multiple pregnancy and congenital anomalies, were recorded. Univariate and multivariate logistic regression, and linear regression were used to investigate the relationship be- tween maternal factors and term LBW. The general incidence of term LBW was 1.70% in the developed area of China. After preliminary analysis using the univariate model, low primary education, anemia, hypertensive disor- ders, placental previa, oligohydramnios and premature rupture of membrane were predicted as independent factors of term LBW in the multivariate model. Furthermore, the decrease in annual frquencies of these risk factors were major causes of gradual decline in the incidence of LBW （from 2.43% in 2001 to 1.21% in 2008）. The study dem- onstrated that among maternal factors, primary education, anemia and hypertensive disorders could contribute to LBW for term birth even in the most developed area of China.

Application of prolonging small feeding volumes early in life to prevent of necrotizing enterocolitis in very low birth weight preterm infants

Objective:To study the effects of prolonging small feeding volumes early in life on the incidence of necrotizing enterocolitis(NEC)in very low birth weight(VLBW)preterm infants.Methods:A total of 128 VLBW infants who could not be breastfed were assigned into the experimental group(63 cases)and the control group(65 cases)using a random number table.The experiment group was fed 12 mL/(kg·d)on day 1 which was increased to 24 mL/(kg·d)for the first 10 study days.The control group was fed 12 mL/(kg·d)for the first 14e48 hours.Then,the feeding volume increased by 24-36 mL/(kg·d)up to 140e160 mL/(kg·d)and maintained until the 10th day after birth.The incidence of feeding intolerance and NEC,duration of hospitalization,time to full enteral feedings,incidence of intrahepatic cholestasis,and the levels of gastrin and motilin in serum were assessed.Results:The incidence of feeding intolerance was significantly lower in the experimental group compared with the control group(15.87% vs.33.84%).There was a significant reduction in the incidence of NEC between the experimental and control groups(7.9% vs.16% in the control group).Conclusion:A protocol that prolongs small feeding volumes early in life can reduce the incidence and severity of NEC,but still warrants further study.

Rescue case of low birth weight infant with acute hepatic failure

We report a case involving a rescued low birth weight infant(LBWI) with acute liver failure. Case: The patient was 1594 g and 32^(3/7) gestational wk at birth. At the age of 11 d, she developed acute liver failure due to gestational alloimmune liver disease. Exchange transfusion and high-dose gamma globulin therapy were initiated, and body weight increased with enteral nutrition. Exchange transfusion was performed a total of 33 times prior to living donor liver transplantation(LDLT). Her liver dysfunction could not be treated by medications alone. At 55 d old and a body weight of 2946 g, she underwent LDLT using an S2 monosegment graft from her mother. Three years have passed with no reports of intellectual disability or liver dysfunction. LBWIs with acute liver failure may be rescued by LDLT after body weight has increased to over 2500 g.

Study on the Relationship between Nursing Staffing and Nosocomial Infection in Very Low Birth Weight Infants

Background: At present, there is no domestic research on the relationship between nurse staffing and hospital infection in very low birth weight infants. In this paper, we will explore the relationship between nurses of very low birth weight (VLBW) infants in neonatal intensive care unit (NICU) and nosocomial infections. Methods: The clinical data of 280 very low birth weight infants born in our hospital from January 2010 to January 2020 were collected, and the chi-square test and multiple logistic regression analysis were used to study the nursing staff of each very low birth weight infant who was admitted to the NICU The relationship between the number of infections and hospital infections. Results: On average, each nurse needs to care for 4.3 very low birth weight infants (lowest to highest: 2.50 - 8.42). In the univariate analysis, the higher the incidence of urinary tract infection (P < 0.05), the multivariate logistic regression analysis of neonatal nosocomial infection showed that nurse staffing was significantly related to the incidence of urinary tract infection (OR = 1.78;95% confidence interval, 1.17 - 2.35, P < 0.05). However, there was no significant correlation between nurse staffing and bloodstream infection (OR = 0.91;95% confidence interval, 0.74 - 1.06, P > 0.05) or Ventilator associated pneumonia (VAP) infection (OR = 1.17;95% confidence interval, 0.94 - 1.47, P > 0.05). Conclusion: Our research shows that in the neonatal intensive care unit, the reasonable deployment of nursing staff is an important factor in preventing urinary tract infections in very low birth weight infants. It is important for improving the survival rate of very low birth weight infants and reducing the occurrence of sequelae.

Association of hypoglycaemia in screening oral glucose tolerance test in pregnancy with low birth weight fetus

BACKGROUND Gestational diabetes mellitus(GDM) is a common metabolic derangement in pregnant women. In the women identified to be at high risk of GDM, a 75 g oral glucose tolerance test(OGTT) at 24-28 wk gestation is the recommended screening test in the United Kingdom as per National Institute for Health and Care Excellence(NICE). Hypoglycaemia following the glucose load is often encountered and the implication of this finding for the pregnancy, fetus and clinical care is unclear.AIM To determine the prevalence of hypoglycaemia at any time during the screening OGTT and explore its association with birth weight.METHODS All deliveries between 2009 and 2013 at the local maternity unit of the University hospital were reviewed. Of the total number of 24,154 women without preexisting diabetes, those who had an OGTT for GDM screening based on NICE recommended risk stratification, who had a singleton delivery and had complete clinical and demographic data for analysis, were included for this study(n =3537). Blood samples for fasting plasma glucose(FPG), 2-hour plasma glucose(2-h PG) and HbA1 c had been obtained. Birth weight was categorised as low(≤ 2500 g), normal or Macrosomia(≥ 4500 g) and blood glucose ≤ 3.5 mmol/L was used to define hypoglycaemia. Binary logistic regression was used to determine the association of various independent factors with dichotomized variables; the differences between frequencies/proportions by χ~2 test and comparison between group means was by one-way ANOVA.RESULTS Amongst the study cohort(3537 deliveries), 96(2.7%) women had babies with LBW(< 2500 g). Women who delivered a LBW baby had significantly lower FPG(4.3 ± 0.6 mmol/L, P = 0.001). The proportion of women who had a 2-h PG ≤ 3.5 mmol/L in the LBW cohort was significantly higher compared to the cohorts with normal and macrosomic babies(8.3% vs 2.8% vs 4.2%; P = 0.007). The factors which predicted LBW were FPG, Asian ethnicity and 2-h PG ≤ 3.5 mmol/L,whereas maternal age, 2-h PG ≥ 7.8 mmol/L and HbA1c were not significant predictors.CONCLUSION A low FPG and 2-h PG ≤ 3.5 mmol/L on 75-gram OGTT are significantly associated with low birth weight in women identified as high risk for GDM.Women of ethnic backgrounds(Asians) appear to be more susceptible to this increased risk and may serve as a separate cohort in whom we should offer more intensive follow up and screening for complications. Cost implications and resources for follow up would need to be looked at in further detail to support these findings.

Determinant of Low Birth Weight Infants: A Matched Case Control Study

Background: Low birth weight (LBW) is a well-known factor associated with neonatal mortality and has contributed to a range of poor health outcomes. Thus, the objective of this study was to determine factors associated with LBW infants. Methods: A matched case control study was conducted in Universiti Kebangsaan Malaysia. Data of deliveries were obtained from Total Hospital Information System and medical records. All registered deliveries from January to June 2012 were used as sample populations. There were 180 pairs of cases and controls matched on babies’ gender. Fourteen variables were analyzed: maternal age, ethnicity, gravida, parity, gestational age, maternal booking weight, height and body mass index (BMI), history of low birth weight infants, birth interval, booking hemoglobin levels, hypertension, diabetes mellitus and mode of delivery. Results: Younger mother (t = 6.947, p < 0.001), lower booking BMI (t = 3.067, p = 0.002), prematurity (t = 12.324, p < 0.001), history of LBW infants (OR = 3.0, p = 0.001), LSCS (OR = 0.06, p = 0.001) and current hypertension (OR = 3.1, p = 0.008) were found significant in bivariate analysis. Multivariable conditional logistic regression identified younger maternal age (AOR = 2.9, 95% CI = 1.86 -4.51, p 13.58, p = 0.045), prematurity (AOR = 2.4, 95% CI = 1.79 -3.26, p < 0.001), and current hypertension (AOR = 4.5, 95% CI = 1.06 -19.22, p = 0.041) as significant factors associated with LBW infants. Conclusion: Younger maternal age, history of LBW infants, prematurity and hypertension have been recognized as predictors of LBW infants. The importance of pre-pregnancy screening, early antenatal booking and proper identification of high risk-mother needs to be strengthened and enforced in effort to reduce incidence of LBW infants.

Prevention of peripherally inserted central catheter-related infections in very low-birthweight infants by using a central line bundle guideline with a standard checklist

Objective:To investigate the effectiveness and feasibility of using a central line bundle(CLB)guideline with a standard checklist in the prevention of peripherally inserted central catheter(PICC)-related infections(CRIs)in very low-birth-weight infants(VLBWIs).Methods:Fifty-seven VLBWIs who underwent PICC insertion at a hospital in Qingdao,China,between November 2012 and June 2013,were monitored with the CLB guideline and a standard checklist.Fifty-three VLBWIs who underwent PICC insertion were monitored by standard hospital procedures.The incidence of CRIs was compared between the two groups.Results:The incidence of infection significantly decreased from 10.0%catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The indwelling catheter time significantly increased in the study group compared to the control group(31.9±15.0days vs.24.8±7.4 days,respectively,p<0.05).Colonization infections also decreased from 6.9% catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The incidence of catheter-related bloodstream infections decreased from 3.1%catheter days in the control group to 0%catheter days in the study group.Conclusion:The use of a CLB guideline with a standard checklist could be an effective and feasible protocol for preventing CRIs and prolonging indwelling catheter timein VLBWIs.

Risk Factors for Low Birth Weight and Preterm Birth：A Population-based Case-control Study in Wuhan,China

Low birth weight（LBW） and preterm birth（PB） are associated with newborn mortality and diseases in adulthood.We explored factors related to LBW and PB by conducting a population-based case-control study from January 2011 to December 2013 in Wuhan,China.A total of 337 LBW newborn babies,472 PB babies,and 708 babies with normal birth weights and born from term pregnancies were included in this study.Information of newborns and their parents was collected by trained investigators using questionnaires and referring to medical records.Univariate and logistic regression analyses with the stepwise selection method were used to determine the associations of related factors with LBW and PB.Results showed that maternal hypertension（OR=6.78,95% CI：2.27–20.29,P=0.001）,maternal high-risk pregnancy（OR=1.53,95% CI：1.06–2.21,P=0.022）,and maternal fruit intake ≥300 g per day during the first trimester（OR=1.70,95% CI：1.17–2.45,P=0.005） were associated with LBW.BMI ≥24 kg/m^2 of mother prior to delivery（OR=0.48,95% CI：0.32–0.74,P=0.001） and gestation ≥37 weeks（OR=0.01,95% CI：0.00–0.02,P〈0.034） were protective factors for LBW.Maternal hypertension（OR=3.36,95% CI：1.26–8.98,P=0.016）,maternal high-risk pregnancy（OR=4.38,95% CI：3.26–5.88,P〈0.001）,maternal meal intake of only twice per day（OR=1.88,95% CI：1.10–3.20,P=0.021）,and mother liking food with lots of aginomoto and salt（OR=1.60,95% CI：1.02–2.51,P=0.040） were risk factors for PB.BMI ≥24 kg/m^2 of mother prior to delivery（OR=0.66,95% CI：0.47–0.93,P=0.018）,distance of house from road ≥36 meters（OR=0.72,95% CI：0.53– 0.97,P=0.028）,and living in rural area（OR= 0.60,95% CI：0.37–0.99,P=0.047） were protective factors for PB.Our study demonstrated some risk factors and protective factors for LBW and PB,and provided valuable information for the prevention of the conditions among newborns.

Neurally adjusted ventilator assist in very low birth weight infants:Current status

Continuous improvements in perinatal care have resultedin increased survival of premature infants.Their immature lungs are prone to injury with mechanical ventilation and this may develop into chronic lung disease(CLD) or bronchopulmonary dysplasia.Strategies to minimize the risk of lung injury have been developed and include improved antenatal management(education,regionalization,steroids,and antibiotics),exogenous surfactant administration and reduction of barotrauma by using exclusive or early noninvasive ventilatory support.The most frequently used mode of assisted ventilation is pressure support ventilation that may lead to patientventilator asynchrony that is associated with poor outcome.Ventilator-induced diaphragmatic dysfunction or disuse atrophy of diaphragm fibers may also occur.This has led to the development of new ventilation modes including neurally adjusted ventilatory assist(NAVA).This ventilation mode is controlled by electrodes embedded within a nasogastric catheter which detect the electrical diaphragmatic activity(Edi) and transmit it to trigger the ventilator in synchrony with the patient's own respiratory efforts.This permits the patient to control peak inspiratory pressure,mean airway pressure and tidal volume.Back up pressure control(PC) is provided when there is no Edi signal and no pneumatic trigger.Compared with standard conventional ventilation,NAVA improves blood gas regulation with lower peak inspiratory pressure and oxygen requirements in preterm infants.NAVA is safe mode of ventilation.The majority of studies have shown no significant adverse events in neonates ventilated with NAVA nor a difference in the rate of intraventricular hemorrhage,pneumothorax,or necrotizing enterocolitis when compared to conventional ventilation.Future large size randomized controlled trials should be established to compare NAVA with volume targeted and pressure controlled ventilation in newborns with mature respiratory drive.Most previous studies and trials were not sufficiently large and did not include longterm patient oriented outcomes.Multicenter,randomized,outcome trials are needed to determine whether NAVA is effective in avoiding intubation,facilitating extubation,decreasing time of ventilation,reducing the incidence ofCLD,decreasing length of stay,and improving long-term outcomes such as the duration of ventilation,length of hospital stay,rate of pneumothorax,CLD and other major complications of prematurity.In order to prevent barotrauma,next generations of NAVA equipment for neonatal use should enable automatic setting of ventilator parameters in the backup PC mode based on the values generated by NAVA.They should also include an upper limit to the inspiratory time as in conventional ventilation.The manufacturers of Edi catheters should produce smaller sizes available for extreme low birth weight infants.Newly developed ventilators should also include leak compensation and high frequency ventilation.A peripheral flow sensor is also essential to the proper delivery of all modes of conventional ventilation as well as NAVA.

Predictors of Low Birth Weight in Newborn Delivered in Public Hospital of Gurage Zone, Southern Ethiopia: A Case-Control Study

Worldwide, low birth weight is one of the most common causes of neonatal morbidity and mortality. Though factors associated with low birth weight vary from one region to another, in Gurage Zone, there is no sound analytical study done to examine the local determinants of low birth weight. Because of this, the study aimed to elucidate the predictors of low birth weight in public hospital of Gurage zone. Methods: A facility based unmatched case-control study design was employed to detect the existing exposure difference between cases and controls. The study included a total of 270 controls (normal weight) and 134 cases (low birth weight baby). Control and case participants were selected through consecutively. To collect the data, structured interviewer administered questionnaires and anthropometric measurement were used. The data were entered through Epi-data 3.1 computer program and analyzed through Statistical package for Social Sciences version 21 (SPSS v. 21). Univariate, Bivariate and Multivariate analysis were done. Result: Multiple logistic regression model analysis indicated that low birth weight was independently associated with maternal mid upper arm circumference less than 23 cm (AOR 1.79 (95% CI = 1.01 - 3.16)), gestational age less than 37 weeks (AOR 24.94 (95% CI = 12.38 - 50.27)), presence of malaria infection during period of pregnancy (AOR 3.02 (95% CI = 1.39 - 6.51)), presence of preclampsia, multiparity (AOR 2.19 (95% CI = 1.21 - 3.96)) and twining (AOR 5.42 95% CI = 2.01 - 14.59). Conclusion: Gestational age < 37 weeks, twining, malaria infection during pregnancy and maternal undernutrition were a significant predictor of LBW in the region of Gurage zone. Hence, to effectively prevent low birth weight, Gurage zone health departments should work on promotion of maternal nutrition during pregnancy, prevention of malaria during pregnancy.

Prevalence and Factors Associated with Low Birth Weight among Teenage Mothers in New Mulago Hospital： A Cross Sectional Study

The World Health Organization defines low birth weight （LBW） as a new born having a weight of less than 2,500 g at birth. Low birth weight is one of the major determinants of perinatal survival, infant morbidity and mortality as well as the risk of developmental disabilities and illnesses in future lives. WHO estimates that about 30 million low birth weight babies are born annually （23.4% of all births） and they often face short and long term health consequences. Whereas the global prevalence of LBW has slightly declined, the rate in many developing countries is still quite high. In Uganda, low birth weight among teenage mothers is a problem. Our study aimed to estimate the prevalence of and identify the factors associated with low birth weight among teenage mothers in New Mulago hospital. We conducted an analytical cross sectional study among teenage mothers who delivered from new Mulago Hospital Complex labour suite from August 2013 to August 2014. Trained interviewers, administered pre-tested questionnaires to consecutive mothers to obtain information on their socio-demographic characteristics, obstetric history and child factors. Odds ratios and P-values were calculated to determine the relationship between independent and dependent variables. We also used descriptive statistics for the quantitative data. A total of 357 teenage mothers were enrolled on the study. Their mean age was 18 years （Range 13-19）, majority, 98.4% aged 15-19 years. The prevalence of LBW was 25.5%. Pre-term delivery （OR 3.3032, P = 0.0001） and multiple pregnancies （OR 0.165, P = 0.039） were associated with LBW. Malaria, young maternal age and ANC attendance were not associated with LBW. Child factors such as birth order, congenital anomalies and sex of the baby were also not associated with LBW. The prevalence of LBW is high among teenage mothers, pre-term delivery and multiple pregnancies were associated factors with LBW. Health professional＇s need to address teenage maternal health. Health workers should encourage teenage mothers to attend focused antenatal care as recommended by the Uganda ministry of Health. A specialized maternal facility centre that is friendly for adolescent/teenage mothers is advisable so as to improve on completion rates and capture high risk teenage mothers early.
