Background: Translocation of the CyaA toxin across plasma membrane is still poorly understood. Results: The region 375-485 is involved in membrane destabilization in vitro and required for cell intoxication.
Conclusion:The region 375-485 is crucial for membrane insertion and translocation of the catalytic domain of CyaA. Significance: These results provide new insights on the early stages of the cell intoxication process.
Though 11.5 cm MUAC has been mentioned by WHO as the cut off for identifying SAM, a higher cut off (12 cm) may be required to use it as a screening tool. Mothers' education, pre-lacteal feeds and co-morbidities were found to be independent determinants for malnutrition in the present patient population, indicating the need towards a targeted approach for modifying these factors.
Background: Neonatal septic arthritis deserves a special attention due to its subtle signs and symptoms and catastrophic consequences. There is paucity of literature regarding the clinical profile and predictors of outcome in neonatal septic arthritis. Objectives: The objective was to study the clinical profile of neonates admitted with septic arthritis, their clinical and radiological outcomes on follow-up, and factors that predict outcomes. Methodology: Neonates with septic arthritis as assessed by retrospective case sheet review were included. Prospective data collection of clinical and radiological outcomes was done during follow-upvisits. Children with good outcomes (controls) were compared to those with poor outcomes (cases) subsequently to identify the predictors of outcomes using a nested case–control design. Results: Data of 70 neonates admitted with septic arthritis were collected. Single joint involvement was common (75.8%), and hip joint was the most common joint involved. Gram-negative organisms were predominant (72%), and Klebsiella was the most common organism isolated from joint aspirate (36%), followed by Escherichia coli and Staphylococcus aureus. Of 52 babies who turned for follow-up, half had poor outcomes. In univariate analysis,multiple joint involvement (odds ratio [OR] 4.79, [confidence interval (CI): 1.14-20.21]), pre-intervention period ?7 days (OR 92, [CI: 14.06-601.9]), culture positive joint aspirate (OR 3.70, [CI: 1.55-11.86]), and restricted range of joint movements at discharge (OR 83.3, [CI: 9.2-749.9]) were significantly associated with poor outcomes. Pre-intervention period ?7 days (adjusted OR 107.99, [CI: 5.16-2258.8]) and restricted joint mobility at discharge (adjusted OR 139.53, [CI: 9.03-2154.04]) were the independent predictors of poor overall outcome by logistic regression analysis. Conclusions: Long pre-intervention period and restricted joint mobility at discharge were independent predictors of poor outcome in neonatal septic arthritis. We emphasize the importance ofearly diagnosis, prompt referral to tertiary centers, timely surgical intervention, appropriate measures to ensure good joint mobility, and regular follow-up in these neonates to achieve best outcomes.
BACKGROUND AND OBJECTIVES:
Hypoglycemia occurs in 5% to 15% of neonates in the first few days. A significant proportion requires admission for intravenous fluids. Dextrose gel may reduce admissions and mother-infant separation. We aimed to study the utility of dextrose gel in reducing the need for intravenous fluids.
METHODS:
This stratified randomized control trial included at-risk infants with asymptomatic hypoglycemia. Study populations were stratified into 3 categories: small for gestational age (SGA) and intrauterine growth-restriction (IUGR), infants of diabetic mothers (IDM) and large for gestational age (LGA), and late preterm (LPT) neonates. Intervention group received dextrose gel followed by breastfeeding, and the control group (CG) received only breastfeeding.
RESULTS:
Among 629 at-risk infants, 291 (46%) developed asymptomatic hypoglycemia; 147 (50.4%) in the dextrose gel group (DGG) and 144 (49.6%) in CG. There were 97, 98, and 96 infants in SGA/IUGR, IDM/LGA, and LPT categories, respectively. Treatment failure in the DGG was 17 (11.5%) compared to 58 (40.2%) in CG, with a risk ratio of 0.28 (95% confidence interval [CI]: 0.17–0.46; P < .001). Treatment failure was significantly less in DGG in all 3 categories: SGA/IUGR, IDM/LGA, and LPT with a risk ratio of 0.29 (95% CI:0.13-0.67), 0.31 (95% CI:0.14–0.66) and 0.24 (95% CI:0.09–0.66), respectively.
CONCLUSIONS:
Dextrose gel reduces the need for intravenous fluids in at-risk neonates with asymptomatic hypoglycemia in the first 48 hours of life.
Preventing maternal death associated with pregnancy and child birth is one of the greatest challenges for India. Approximately 55,000 women die in India due to pregnancy- and childbirth- related conditions each year. Increasing the coverage of maternal and newborn interventions is essential if Millennium Development Goals (MDG) 4 and 5 are to be reached. With a view to accelerate the reduction in maternal and neonatal mortality through institutional deliveries, Government of India initiated a scheme in 2005 called Janani Suraksha Yojna (JSY) under its National Rural Health Mission (NRHM). In Jharkhand the scheme is called the Mukhya Mantri Janani Shishu Swasthya Abhiyan (MMJSSA). This paper focuses on community perspectives, for indentifying key areas that require improvement for proper implementation of the MMJSSA in Jharkhand. Qualitative research method was used to collect data through in-depth interviews (IDIs) and focus group discussions (FGDs) in six districts of Jharkhand- Gumla, West Singhbhum, Koderma, Deoghar, Garhwa, and Ranchi. Total 300 IDIs (24 IDIs each from mother given birth at home and institution respectively; two IDIs each with members of Village Health and Sanitation Committees (VHSC) / Rogi Kalyan Samitis (RKS) from each district) and 24 FGDs (four FGDs were conducted from pools of husbands, mothers-in-law and fathers-in-law in each district) were conducted. Although people indicated willingness for institutional deliveries (generally perceived to be safe deliveries), several barriers emerged as critical obstacles. These included poor infrastructure, lack of quality of care, difficulties while availing incentives, corruption in disbursement of incentives, behavior of the healthcare personnel and lack of information about MMJSSA. Poor (and expensive) transport facilities and difficult terrain made geographical access difficult. The level of utilization of maternal healthcare among women in Jharkhand is low. There was an overwhelming demand for energizing sub-centers (including for deliveries) in order to increase access to maternal and child health services. Having second ANMs will go a long way in achieving this end. The MMJSSA scheme will thus have to re-invent itself within the overall framework of the NRHM.
Various less invasive surfactant administration strategies like surfactant replacement therapy via thin catheters, laryngeal mask airway, pharyngeal instillation, and nebulized surfactant are increasingly being practiced to avoid the harmful effects of endotracheal intubation and ventilation. Numerous studies have been done to study surfactant replacement via thin catheters whereas little data is available for other methods. However, there are variations in premedication policies, type of respiratory support used in these studies. Surfactant delivery using thin catheters has been reported to be associated with decrease in the need for mechanical ventilation (MV), duration of MV, bronchopulmonary dysplasia and neonatal mortality. With the current evidence, among all the available surfactant delivery methods, the one using thin catheters appears to be the most feasible and beneficial to improve clinical neonatal outcomes.
