Gestational age specific anthropometric postnatal percentile charts for neonates born at tertiary hospital in Eastern Nepal.

BACKGROUND AND OBJECTIVES: Birth weight, Head circumference (HC), and Length are important clinical indicators for evaluation of prenatal growth and identification of neonates requiring detail assessment and monitoring. Gestational age-specific percentile charts are essential tool for both obstetricians and pediatricians in their day to day practice. This study aimed to develop gestational age specific percentile chart of Birth weight, Length and HC for neonates. METHODS: In this Cross sectional observational study, HC, Birth weight and Length of live singleton neonates from 28 to 42 weeks of gestation fulfilling the inclusion criteria were measured over a period of one year. Mean, standard deviation, and percentiles values for different gestational age were calculated. Graphs were constructed using two way graph and Lowess smoothening method. RESULTS: Of total 2662 neonates, male: female ratio was 1.3:1 with maximum neonates in 40 weeks of gestation. The mean Birth weight, HC and Length was 2852.02 gm, 33.6 and 48.42 cm respectively. Overall males have more mean weight than females by 46.35gms. However, mean HC of male and female were similar 33.6 and 33.61 cm respectively and on average males were 0.27 cm longer compared to female. The mean Birth weight, HC and Length at 40 weeks was 3123.43gm (± 427.82), 34.249 cm (± 0.87) and 49.61 cm(± 1.85) respectively. The 10th, 50th and 90th percentile at 40 weeks for Birth weight being 2550gm, 3100gm and 3750gm respectively. The gestational age specific percentile chart and growth curve are appropriately placed in the manuscript. CONCLUSIONS: The percentile charts in this study may be used as reference for local population and similar data from various parts of the nation can provide a national reference curve for healthy neonates.

Microbiological and Clinicoepidemiological Profile of a Series of Patients with Infective Endocarditis at a Center in Eastern Nepal.

BACKGROUND: The microbiological and clinicoepidemiological profile of infective endocarditis (IE) has undergone significant change over time. The pattern of IE studied at local level provides broader vision in understanding the current scenario of this disease. This study aimed to depict the overall picture of IE and its changing profile by evaluating the microbiological and clinicoepidemiological features in the context of a tertiary care center of eastern Nepal. METHODS: The descriptive study was conducted from September 2017 to August 2018 among IE patients presenting to B. P. Koirala Institute of Health Sciences, Nepal. Detailed history and clinical manifestations of patients were noted. Microorganisms isolated from the blood culture were processed for identification by standard microbiological methods, and susceptibility testings were done. Each patient was assessed daily during hospital stay. RESULTS: Ten definite and 7 possible endocarditis cases were studied. The mean age was 41.4 ± 15.85 (17-70) years with predominance of male (4.7 : 1). Rheumatic heart disease (41.1%) was the most common underlying heart disease observed followed by injection drug user endocarditis (23.5%). All the cases had native valve endocarditis. Aortic valve was the most common valve involved (35.3%) followed by mitral, tricuspid, and pulmonary valves. Blood culture positivity was 53%. Staphylococcus aureus was the major causative agent responsible for 23.5% of the cases followed by Enterococcus faecium, Enterococcus faecalis, and Pseudomonas aeruginosa. Mortality of 2 cases (11.8%) was associated with S. aureus and P. aeruginosa. Majority of patients developed acute kidney injury (35.3%) and congestive cardiac failure (23.5%). CONCLUSION: IE patients in our center exhibited differences from the west in terms of age at presentation and predisposing factors but held similarity in terms of commonly isolated microorganisms. The changing patterns of IE, etiological agents, and their antimicrobial susceptibility observed in this study may be helpful for clinicians in formulating a new empirical antibiotic treatment protocol.

Clinical, Bacteriological Profile and Outcome of Neonatal Sepsis.

BACKGROUND: Sepsis is a major cause of morbidity and mortality among neonates in Nepal. This study was conducted to determine the clinical-bacteriological profile, their antibiotic susceptibility patterns, and clinical outcome of culture-positive neonatal sepsis. METHODS: This was a prospective study conducted at B.P Koirala Institute of Health Sciences from July 2018 to June 2019. Neonates with clinically diagnosed sepsis having blood culture positive were included in the study. Blood samples culture and antimicrobial susceptibility testing were performed with the standard microbiological method. Demographic, clinical information, and clinical outcomes were documented. RESULTS: The incidence of culture-positive sepsis was 10.3% (183/1773) of neonatal admissions. Poor feeding 85(46%) and fever 68(37%) were the common clinical features at presentation. The incidence of early-onset sepsis and late-onset sepsis were found to be 116 (63%) and 67(37%) respectively. Staphylococcus aureus was the common pathogen in both early-onset 61(49%) and late-onset 34(41%) sepsis. The incidence of multidrug-resistant cases was 41% (75/183) with 20% (15/75) extensively drug-resistant gram-negative bacilli, 36% (20/75) multidrug-resistant gram-negative bacilli, and 44% (33/75) Methicillin-resistant Staphylococcus aureus cases. In-hospital mortality rate was 12 (7%) with a higher frequency in multidrug-resistant sepsis 92% (11/12) than non- multidrug-resistant 8% (1/12). The median hospital days were longer in multidrug-resistant cases than non- multidrug-resistant [11(9-13) verses 3(2-5)]. CONCLUSIONS: The incidence of multidrug-resistant pathogens causing neonatal sepsis is high at our hospital and are associated with more in-hospital mortality and longer hospital stay. Implementation of effective preventive strategies to combat the emergence of antimicrobial resistance is immediately needed.

Prevalence of electrolyte disturbances in perinatal asphyxia: a prospective study.

BACKGROUND: Birth asphyxia is defined as the presence of hypoxia, hypercapnia, and acidosis leading the newborn to systemic disturbances probably electrolyte disturbance also. Knowledge of these electrolyte disturbances is very valuable as it can be an important parameter affecting perinatal morbidity, mortality and ongoing management. METHODS: Serum sodium, potassium and ionized calcium of asphyxiated term newborn were sent within one hour of birth as per the inclusion criteria. Statistical comparison of mean values of different electrolytes between different groups of perinatal asphyxia was performed by ANOVA test for parametric data and significant data were further analyzed using post hoc test. Bivariate analysis was done to determine the correlations between Apgar score at 5 min and serum electrolytes. Pearson test was used to calculate the correlation coefficient. Box plot was used to show the median and quartile between serum electrolytes and Apgar score at 5 min. RESULT: The mean values of sodium for mild, moderate and severe asphyxia were 135.52, 130.7 and 127.15 meq/l respectively. The values of potassium for mild, moderate and severe asphyxia were 4.96, 5.93 and 6.78 meq/l respectively. Similarly, the mean values of ionized calcium for mild, moderate and severe asphyxia were 1.07, 1.12 and 0.99 mmol/l respectively. The values of sodium and potassium among different severity of asphyxia were significantly different (p-value< 0.001). Significant positive correlation was found between serum sodium and Apgar score at 5 min. Significant negative correlation was present between serum potassium and Apgar score at 5 min. CONCLUSION: The degree of hyponatremia and hyperkalemia was directly proportional to the severity of birth asphyxia. So these electrolyte disturbances should always be kept in mind while managing cases of perinatal asphyxia and should be managed accordingly.

Moving forward on strengthening and sustaining National Immunization Technical Advisory Groups (NITAGs) globally: Recommendations from the 2nd global NITAG network meeting.

National Immunization Technical Advisory Groups (NITAGs) provide independent, evidence-informed advice to assist their governments in immunization policy formation. This is complex work and many NITAGs face challenges in fulfilling their roles. Inter-country NITAG collaboration opportunities have the potential to enhance NITAG function and grow the quality of recommendations. Hence the many requests for formation of a network linking NITAGs together so they can learn from each other. The first Global NITAG Network (GNN) meeting, held in 2016, led to a push to launch the GNN and grow the network. At the second GNN meeting, held June 28-29, 2017 in Berlin, the GNN was formally inaugurated. Participants discussed GNN governance, reflected on the April 2017 Strategic Advisory Group of Experts (SAGE) on Immunization conclusions concerning strengthening of NITAGs and also shared NITAG experiences in evaluation and inter-country collaborations and independence. They also discussed the role of Regional Technical Advisory Groups on Immunization (RTAGs) and regional networks. A number of issues were raised including NITAGs and communications, dissemination of recommendations and vaccine implementation as well as implications of off-label recommendations. Participants were alerted to immunization evidence assessment sites and value of sharing of resources. They also discussed potential GNN funding opportunities, developed an action plan for 2017-18 and selected a Steering Committee to help move the GNN forward. All participants agreed on the importance of the GNN and the value in attracting more countries to join the GNN.

Status of gastric lavage in neonates born with meconium stained amniotic fluid: a randomized controlled trial.

BACKGROUND: Neonates born with meconium stained amniotic fluid (MSAF) can develop feed intolerance during first few days of post -natal period. A randomized controlled trial was conducted with the objectives of to find out the incidence of feed intolerance in vigorous neonates with MSAF who received gastric lavage (GL) as compared to those in whom it was not performed. METHODS: This was a randomized controlled trial on 500 neonates satisfying the inclusion criteria, 230 were allocated to GL and 270 to no lavage group through computer generated random numbers. RESULTS: No significant difference in the incidence of vomiting was found between GL and no lavage group (8.7 % vs 11.5 %, p = 0.305). Feed intolerance had no relationship with gestational age, gender, birth weight and mode of delivery. No neonates of GL group developed any complications related to the procedure. CONCLUSION: Thus, it may be concluded that gastric lavage is not required in neonates born with MSAF.
