RESUMO
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.

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.
RESUMO
BACKGROUND: There are many scoring systems to predict neonatal mortality and morbidity in neonatal intensive care units (NICU). One of the scoring systems is SNAPPE-II (Score for Neonatal Acute Physiology with Perinatal extension-II). This study was carried out to assess the validity of SNAPPE-II score (Score for Neonatal Acute Physiology with Perinatal Extension-II) as a predictor of neonatal mortality and duration of stay in a neonatal intensive care unit (NICU). METHODS: This prospective, observational study was carried out over a period of 12 months from June 2015 to May 2016. Two hundred fifty five neonates, who met the inclusion criteria admitted to NICU in tertiary care hospital, BPKIHS Hospital, Nepal were enrolled in the study and SNAPPE-II score was calculated. Receiver Operating Characteristic (ROC) curve was constructed to derive the best SNAPPE-II cut-off score for mortality. RESULTS: A total of 305 neonates were admitted to NICU over a period of one year. Among them, 255 neonates fulfilled the inclusion criteria. Out of 255 neonates, 45 neonates (17.6%) died and 210 were discharged. SNAPPE-II score was significantly higher among neonates who died compared to those who survived [median (IQR) 57 (42-64) vs. 22 (14-32), P < 0.001]. SNAPPE II score had discrimination to predict mortality with area under ROC Curve (AUC): 0.917 (95% CI, 0.854-0.980). The best cut - off score for predicting mortality was 38 with sensitivity 84.4%, specificity 91%, positive predictive value 66.7% and negative predictive value 96.5%. SNAPPE II score could not predict the duration of NICU stay (P = 0.477). CONCLUSION: SNAPPE- II is a useful tool to predict neonatal mortality in NICU. The score of 38 may be associated with higher mortality.

BACKGROUND: Recent reports indicated high miltefosine treatment failure rates for visceral leishmaniasis (VL) on the Indian subcontinent. To further explore the pharmacological factors associated with these treatment failures, a population pharmacokinetic-pharmacodynamic study was performed to examine the relationship between miltefosine drug exposure and treatment failure in a cohort of Nepalese patients with VL. METHODS: Miltefosine steady-state blood concentrations at the end of treatment were analyzed using liquid chromatography tandem mass spectrometry. A population pharmacokinetic-pharmacodynamic analysis was performed using nonlinear mixed-effects modeling and a logistic regression model. Individual estimates of miltefosine exposure were explored for their relationship with treatment failure. RESULTS: The overall probability of treatment failure was 21%. The time that the blood concentration was >10 times the half maximal effective concentration of miltefosine (median, 30.2 days) was significantly associated with treatment failure: each 1-day decrease in miltefosine exposure was associated with a 1.08-fold (95% confidence interval, 1.01-1.17) increased odds of treatment failure. CONCLUSIONS: Achieving a sufficient exposure to miltefosine is a significant and critical factor for VL treatment success, suggesting an urgent need to evaluate the recently proposed optimal allometric miltefosine dosing regimen. This study establishes the first evidence for a drug exposure-effect relationship for miltefosine in the treatment of VL.

BACKGROUND: The use of Childhood Asthma Control Test (C-ACT) has been advised for monitoring asthma control by the Global Initiative for Asthma (GINA) guidelines. OBJECTIVE: To validate the tool C-ACT for the assessment of control of asthma and to examine the correlation between C-ACT score and lung function assessed by forced expiratory volume in one second (FEV1). METHODS: This was a prospective observational study conducted between January 2010 to January 2011. Children diagnosed to have bronchial asthma and aged 5 to 14 years, were enrolled in the study. Asthma severity and control status were classified according to the National Asthma Education and Prevention Programme (NAEPP) and GINA guidelines, respectively. Patients were followed-up at three and six months and C-ACT and spirometric measurements were obtained. RESULTS: Significant positive correlations were found between C-ACT score and FEV1 at enrollment (r = 0.772) (p < 0.001), three months (r = 0.815) (p < 0.001) and at six months follow-up (r = 0.908) (p < 0.001). Baseline C-ACT score was useful for predicting the levels of control of asthma upto three months (0.004), but not at six months follow-up (0.787). A cut-off C-ACT value of > or = 19 had a sensitivity, specificity, positive predictive value, negative predictive value and area under the curve (AUC) 98.5%, 89.1%, 94.9%, 96.6%, 0.717, respectively for the control of asthma. CONCLUSION: C-ACT is a simple and feasible tool to assess and predict the levels of control in children with bronchial asthma upto three months.

Introduction Several studies have reported the usefulness of measuring lower limb muscle strength through the motion of standing up using a reaction force measuring device positioned on the ground. There is inadequate information on the association between cardiovascular disease risk factors and ground reaction force (GRF) during standing up. Therefore, this study estimated the association between GRF by sit-to-stand movements and cardiovascular disease risk factors in a health check-up population. Methods This cross-sectional study included 1,182 healthy participants without chronic diseases who underwent periodic health check-ups from August 2019 to December 2020. The study included individuals aged ≥20 years who underwent a standing test from an initial seated position in a chair. A sit-to-stand force analyzer was used to measure GRF, and health status information was collected at enrollment. The relationships between blood test data and each measurement obtained from GRF measurements (forth/body mass (F/M), rate of forth development/body mass (RFD/M), and stable time) were parsed according to sex using linear regression analysis coordinated by age. GRF measurements and their relationships with cardiovascular disease risk factors were assessed using logistic regression analysis, adjusted for age and sex. Results A total of 1,182 participants was included in this study, with male participants accounting for 61.5%. The study participants had a median age of 57.0 years (IQR: 47.0-63.0). After adjusting for age, F/M was positively associated with high-density lipoprotein cholesterol in male (ß=22.59, p<0.001) and female participants (ß=20.35, p=0.011) and negatively associated with plasma glucose in male (ß=-16.25, p=0.008) and female participants (ß=-18.78, p=0.028). Stable time (time required to be stabilize after standing up movement) was positively associated with hemoglobin A1c levels in male (ß=0.55, p=0.001) and female participants (ß=0.56, p=0.036). Logistic regression analysis adjusted by age and sex showed that a lower F/M ratio was associated with hypertension, hyperlipidemia, and diabetes mellitus (adjusted odds ratio (aOR) =1.60, p=0.01; aOR=1.75, p=0.001; and aOR=2.23, p=0.002, respectively). Lower RFD/M was associated with hyperlipidemia and diabetes mellitus (aOR=1.46, p=0.013 and aOR=1.63, p=0.045, respectively). A shorter stable time was associated with diabetes mellitus (aOR=0.39, p<0.001). Conclusions These findings suggest that lower limb function impairment, as assessed via standing-up movements using a GRF-measuring device, may relate to cardiovascular disease. Further research is needed to confirm this association.
RESUMO
Background: This study investigates how lifestyle factors and westernization contribute to obesity and examines the influence of body mass index (BMI) changes and lifestyle factors on "lipitension," a significant risk factor for heart disease and metabolic syndrome. Methods: This prospective study focused on women aged 20-64 without pre-existing hypertension and dyslipidemia who underwent regular medical checkups between April 2016 and March 2022. Anthropometric measurements and blood pressure, along with low-density lipoprotein, high-density lipoprotein, and triglycerides levels, were assessed. Results: Over an average 46.5-month follow-up, 11.5% of initially healthy young and middle-aged women developed lipitension. Categorizing participants based on BMI changes revealed stable (63.8%), decreased (12.5%), and increased (23.8%) groups within this 11.5%. Increased BMI is linked with a heightened hazard risk for lipitension. Women with increased BMI who refrained from snacking (aHR [95% confidence interval (CI)] = 2.750 [1.433-5.279]), avoided late-night eating (aHR [95% CI] = 1.346 [1.032-1.754]), and engaged in alcohol consumption (aHR [95% CI] = 2.037 [1.138-3.646]) showed an elevated risk. Conversely, within the decreased BMI group, behaviors like skipping breakfast (aHR [95% CI] = 0.190 [0.047-0.764]), eating quickly (aHR [95% CI] = 0.457 [0.215-0.972]), and not eating late (aHR [95% CI] = 0.665 [0.467-0.948]) were associated to a reduced lipitension. Subgroup analysis for women with BMI <23 revealed specific behaviors influencing lipitension risk in both BMI-increased and BMI-stable groups. Conclusion: Customized interventions, including for women with BMI <23, enhance heart health, mitigating global lifestyle diseases and obesity.
RESUMO
The fracture strength of implant supported zirconia-titanium base (Zi-Ti) base restorations with and without modification of submucosal cervical contour is of interest to dentists. 80 zirconia specimens were adjusted onto the Ti-base. One category consisted of specimens that underwent modification. Other category consisted of abutments without modification. There was polishing and recon touring at the interface of Zi-Ti base in cervical regions. Using the universal testing apparatus fracture resistance was assessed for every sample in every category in Newtons (N). The fracture strength of abutments with modification ranged between 4465.79 - 6523.50 N with mean value of 5604.24 ± 497.62 N. On the other hand, values of fracture strength varied between 5511.42 - 7064.33 N. in abutments without modification with mean fracture strength values of 6265.95 ± 331.61. It was observed that the fracture strength was lesser in abutments that underwent modification.
RESUMO
BACKGROUND: Miltefosine (MIL), the only oral drug for visceral leishmaniasis (VL), is currently the first-line therapy in the VL elimination program of the Indian subcontinent. Given the paucity of anti-VL drugs and the looming threat of resistance, there is an obvious need for close monitoring of clinical efficacy of MIL. METHODS: In a cohort study of 120 VL patients treated with MIL in Nepal, we monitored the clinical outcomes up to 12 months after completion of therapy and explored the potential role of drug compliance, parasite drug resistance, and reinfection. RESULTS: The initial cure rate was 95.8% (95% confidence interval [CI], 92.2-99.4) and the relapse rate at 6 and 12 months was 10.8% (95% CI, 5.2-16.4) and 20.0% (95% CI, 12.8-27.2) , respectively. No significant clinical risk factors of relapse apart from age <12 years were found. Parasite fingerprints of pretreatment and relapse bone marrow isolates within 8 patients were similar, suggesting that clinical relapses were not due to reinfection with a new strain. The mean promastigote MIL susceptibility (50% inhibitory concentration) of isolates from definite cures was similar to that of relapses. Although more tolerant strains were observed, parasite resistance, as currently measured, is thus not likely involved in MIL treatment failure. Moreover, MIL blood levels at the end of treatment were similar in cured and relapsed patients. CONCLUSIONS: Relapse in one-fifth of the MIL-treated patients observed in our study is an alarming signal for the VL elimination campaign, urging for further review and cohort monitoring.

Rapid diagnostic tests (RDTs) based on the detection of specific antibodies in serum are commonly used for the diagnosis of visceral leishmaniasis (VL). Several commercial kits are available, and some of them allow the use of whole-blood samples instead of serum. An RDT is much more user-friendly for blood samples than for serum samples. In this study, we examined the sensitivities and specificities of six different commercially available immunochromatographic tests for their accuracy in detecting Leishmania infection in whole blood and serum of parasitologically confirmed VL cases. This study was performed in areas of India and Nepal where VL is endemic. A total of 177 confirmed VL cases, 208 healthy controls from areas of endemicity (EHCs), 26 malaria patients (MP), and 37 tuberculosis (TB) patients were enrolled. The reproducibilities of the blood and serum results and between-reader and between-laboratory results were tested. In India, the sensitivities of all the RDTs ranged between 94.7 and 100.0%, with no significant differences between whole blood and serum. The specificities ranged between 92.4 and 100.0%, except for the specificity of the Onsite Leishmania Ab RevB kit, which was lower (33.6 to 42.0%). No differences in specificities were observed for blood and serum. In Nepal, the sensitivities of all the test kits, for whole-blood as well as serum samples, ranged between 96.3 and 100.0%, and the specificities ranged between 90.1 and 96.1%, again with the exception of that of the Onsite Leishmania Ab RevB test, which was markedly lower (48.7 to 49.3%). The diagnostic accuracies of all the tests, except for one brand, were excellent for the whole-blood and serum samples. We conclude that whole blood is an adequate alternative for serum in RDTs for VL, with sensitivities and specificities comparable to those obtained in serum samples, provided that the test kit is of overall good quality.

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.

Acute kidney injury (AKI) is common in premature newborns and is associated with high mortality. It is unclear which risk factors lead to AKI in these neonates. We aimed to determine the incidence, risk factors, and outcomes of AKI in preterm neonates in the neonatal intensive care unit (NICU). They were screened and staged for AKI as per the amended neonatal criteria of Kidney Disease Improving Global Outcomes and followed up until discharge or death. Serum creatinine levels and urine output were measured. The incidence of AKI was 18.5% (37/200 neonates). The majority developed non-oliguric AKI. The risk factors significantly associated with AKI in neonates were the presence of sepsis, birth asphyxia, shock, respiratory distress syndrome, and hypothermia. The majority of neonates with AKI had a birthweight <1500 g and a gestational age of <32 weeks and had a higher risk of mortality, in contrast to than those without AKI. Mortality and NICU stay were significantly higher among those with Stage 3 AKI compared with Stage 2 and Stage 1 AKI. To prevent AKI and reduce the burden of high mortality in premature neonates, it is essential to prevent sepsis, birth asphyxia, and respiratory distress syndrome, as well as to detect shock and patent ductus arteriosus as early as possible. There is a need for good antenatal care to reduce the burden of prematurity.

Background: Being underweight, overweight, or obese can lead to adverse health effects. Hence, it is important to understand the specific factors that change the burden of underweight and overweight to target appropriate disease control strategies. This study was designed to examine the prevalence and factors associated with underweight and overweight among young and middle-aged women in Japan. Materials and Methods: A cross-sectional study was conducted among women aged 20-59 years who participated in health checkups at a regional health care center in 2018 and 2019 (N = 1722). The assessments included anthropometric, blood pressure measurements, and a standardized self-administered questionnaire. Multivariable logistic regression analysis assessed lifestyle factors associated with body mass index for underweight <18.5 kg/m2) and overweight/obesity (25.0 kg/m2 and above). Results: The prevalence of underweight and overweight/obesity were 12.3%, and 22.5%, respectively. No lifestyle factors were found to be significantly associated with being underweight. Having dinner within 2 hours before bed was positively associated with being overweight/obese [adjusted odds ratio (AOR): 1.448, 95% confidence interval (CI): 1.014-2.068]. Women who gained 10 kg since their 20s were more likely to fall into overweight/obesity category (AOR: 9.674, 95% CI: 1.014-2.068). Women who were using a lipid-lowering medication (AOR: 3.150, CI: 1.892-5.246) were associated with three times higher risk of being overweight/obese. Hypertension and dyslipidemia were significantly associated with overweight/obesity (AOR: 3.094, 95% CI: 2.201-4.351 and AOR: 2.498, 95% CI: 1.831-3.409, respectively). Conclusion: One in five middle-aged women was overweight or obese, whereas one in eight was underweight. In relation to the prevention of overweight/obesity, specific health promotion messages regarding eating timing should be developed.
RESUMO
Preventing vaccine freezing is one of the biggest challenges in vaccine management. Until 2018, vaccine carriers used in the immunization program lacked features to prevent vaccine freezing. Freeze-preventive vaccine carriers (FPVCs) have an engineered liner that buffers vaccines from direct exposure to frozen ice packs. A field evaluation of three FPVCs was conducted in 24 health posts in eastern Nepal. The objective was to evaluate the FPVCs' performance, acceptability, systems fit, and cost, to inform prequalification and introduction planning. The study was carried out in two phases: in the first phase, FPVCs containing dummy vaccines (labeled "Not for Human Use") were transported to outreach sessions along with a standard vaccine carrier (SVC); in the second phase, the FPVCs were used for transporting vaccines taken to outreach sessions and used for vaccinating eligible children. The study gathered quantitative and qualitative data from health workers, logbooks, and electronic temperature monitors placed inside and outside the FPVCs. Results indicate the FPVCs successfully prevented temperatures below 0 °C more than 99% of the time-except at one site, where ambient temperatures were below the minimum rated testing temperature specified by the World Health Organization. Internal cool-down times for the FPVCs were highly variable, as were mean kinetic temperatures, possibly driven by the wide range of ambient temperatures and higher-than-expected variations in freezer performance, which, along with the need to transport ice packs to some locations, affected ice-pack temperatures. Almost all health workers requested smaller, lighter-weight FPVCs but appreciated the FPVCs' ability to prevent vaccines from freezing while avoiding undue heat exposure. FPVCs had benefit-cost ratios greater than 1 and hence good value for money. Results point to the importance of understanding the intended environment of use and the need for smaller, short-range as well as long-range carriers.
RESUMO
BACKGROUND: Pelvic organ prolapse (POP) is one of the main contributors to reproductive health problems that affect women's quality of life. Previous studies have reported the risk factors and prevalence of POP. The aim of this study is to examine the association between POP and short birth intervals in a rural area of Nepal. METHODS: A cross-sectional study was conducted in Panchapuri municipality, located in Surkhet District of Karnali Province in Nepal. A questionnaire was used to collect information on POP, birth intervals, and other known confounding factors, such as age and parity. Multiple logistic regression analysis was used to examine the association between minimum birth intervals and POP. RESULTS: The study recruited 131 women. The prevalence of POP was 29.8%. The mean (SD) of maternal age was 32.3 (0.7) years. The median parity was 2, with a range of 2-6 children. More than half (64.9%) of the women reported a minimum birth interval of less than 2 years. Maternal age at birth, minimum birth interval, parity, and latest birth interval were significantly associated with POP in univariate analyses. After adjusting for the potential confounding factors such as age and occupation, the minimum birth interval was significantly associated with POP [AOR = 3.08, 95% CI 1.04-9.19]. CONCLUSION: The prevalence of POP was high in this rural area of Nepal. Age, parity, occupation, and minimum birth interval were significantly associated with POP.
RESUMO
INTRODUCTION: Thrombocytopenia is a condition characterized by abnormally low levels of thrombocytes, also known as platelets, in the blood. Several medicinal plants possess curative and protective effect against thrombocytopenia associated with diseases or drugs. AIM: In the present study, we have investigated the platelet augmentation activity of polyherbal formulation (VITA PLAT Capsule) in cyclophosphamide-induced thrombocytopenic rat model. MATERIALS AND METHODS: Twenty-four albino Wistar rats were divided into four groups. Thrombocytopenia was induced in the rats by administering cyclophosphamide (25 mg/kg, i.p.) for three days to all the groups except normal controls. The test groups were given orally a polyherbal formulation suspended in normal saline for 14 days. Blood was withdrawn from the retro-orbital plexus of the rats on days 1, 7, and 14 of study to determine platelet counts in all groups. Clotting time and bleeding time were determined on the last day of study. Data were collected and analyzed using GraphPad Prism 8. RESULTS: The results showed that the polyherbal formulation treatment could significantly ameliorate platelet count in thrombocyto-penic rats in the initial as well as in the later phase. The total WBC count was also improved during later phase in test groups. However, there is no significant difference between clotting time and bleeding time in all groups. CONCLUSIONS: Our study suggests a potential role of this formulation in the augmentation of platelet counts in various thrombocyto-penic disorders including a role in ameliorating the haemorrhagic complications of dengue fever.

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.

In most of the Indian subcontinent, the first line treatment for visceral leishmaniasis (VL) is sodium stibogluconate (SSG), an antimonial drug, but the efficacy of the drug varies according to region. We aimed to characterize the in vitro antimony susceptibility of clinical isolates of Nepalese VL patients, and to correlate this in vitro parasite phenotype to clinical therapy outcome. Thirty-three clinical isolates of L. donovani were taken from patients with known disease history. These isolates were typed and the susceptibility of intracellular amastigotes to pentavalent (SbV) and trivalent (SbIII) antimonials was determined. We observed (i) 22 SbV-resistant isolates out of 33 tested and (ii) 3 SbIII-resistant isolates out of 12 tested. Amongst the latter, there were three combinations of in vitro phenotypes: (i) parasites sensitive (n=4) or (ii) resistant to both drugs (n=3) and (iii) resistant to SbV only (n=5). There was no geographical clustering in terms of in vitro susceptibility. The relation between the in vitro susceptibility to antimonials and the corresponding in vivo treatment outcome was ambiguous. Our results highlight the need to adjust the currently used Leishmania drug susceptibility assays if they are to be used for prognosis of in vivo SSG treatment outcome.

Pentavalent antimonials (SbV) are the first line drug against leishmaniasis worldwide, but drug resistance is increasingly reported, particularly in the Indian sub-continent, where it represents a major threat for the control of anthroponotic visceral leishmaniasis (VL). In order to understand the epidemiological dynamics of antimonial resistance in anthroponotic VL, we analysed here the population structure of 24 Leishmania donovani stocks isolated from anthroponotic VL-patients from Eastern Nepal: 13 SbV-naturally resistant and 11 SbV-sensitive, as demonstrated by in vitro drug susceptibility assays. The parasites were genotyped by PCR-RFLP analysis of kDNA minicircles and by microsatellite analysis and the encountered polymorphism revealed a polyclonal structure among resistant isolates. Furthermore, analysis of paired samples obtained from the same patients before treatment and after failure revealed primary as well as acquired resistance. The hypothesis of independent events of drug resistance emergence is proposed and confronted to alternative explanations. Our results show the dynamics of drug resistance epidemiology and highlight the importance of surveillance networks.

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.
