Risk Factors for Relapse in Childhood Nephrotic Syndrome.

Minimal change nephrotic syndrome is the most common cause of the glomerular disease in children. Despite its high initial response to corticosteroids, relapses are common leading to increased morbidity. Therefore, appraisal of common triggers of relapse becomes an imperative for successful management of childhood nephrotic syndrome. The objective of the study was to identify the risk factors for frequent relapse in childhood nephrotic syndrome. This descriptive cross-sectional study was conducted in the department of Paediatrics, Rangpur Medical College Hospital, Bangladesh from January 2013 to December 2014. A total of 60 patients with relapsed idiopathic childhood nephrotic syndrome fulfilling the selection criteria were enrolled into the study. Serum total protein, serum albumin and urine culture were done. The following potential risk factors for relapse were analyzed using Chi-square test: age at onset of NS, sex, socioeconomic status, atopy, short duration of initial therapy with steriod, serum total protein, serum albumin level and infection. Among 60 patients, short duration of therapy with steriod (<8 weeks) for first attack was significantly higher among frequent relapse (FRNS) cases compared with infrequent relapse (IFRNS) group (63% vs. 27.27%). FRNS group had initial brief period of remission of <6 months, (p=0.04). Difference in mean serum albumin and that of serum total protein between FRNS and IFRNS cases was (1.0±0.66 vs. 2.66±1.6gm/dl) (p<0.0001) and (3.5±1.2 vs. 6.5±2.12gm/dl) (p<0 .0001) respectively. This study concluded that short initial therapy with corticosteroid, brief duration of initial remission; low serum total protein and decreased serum albumin were the risk factors for frequent relapses.

Comparison of WHO Clinical Criteria and Radiological Findings of Pneumonia in Children Aged 02-59 Months.

Despite recent advances, pneumonia contributes substantially to childhood mortality in low and middle-income countries. To reduce case fatality, World Health Organization (WHO) adopted a working formula to identify pneumonia clinically in resource constrained setting. Chest X-ray is the gold standard test to diagnose pneumonia but this tool is not readily available or affordable in primary health facility in developing countries even when it is indicated. Objective of the study was to compare WHO clinical criteria and radiological findings of pneumonia in children aged 02-59 months. This cross-sectional observational study was conducted at inpatient department of Paediatrics of Rangpur Medical College Hospital from July 2015 to June 2017. Total 112 patients aged 2 to 59 months fulfilling selection criteria were enrolled into this study. Data were collected and chest X-ray was done for each patient. Data were analyzed through SPSS software (version 16.0). Minimum level of significance was predetermined as p<0.05. Among 112 patients, mean age of chest radiograph positive cases of pneumonia was 7.64±7.08 months and that of negative cases 10.75±10.95 months. There was no statistically significant difference of age (p=0.083) between chest radiography positive and negative cases. Radiological findings were positive in 52(46.43%) cases and negative in 60(53.57%). Fever, cough and fast breathing were present in all patients with sensitivity 100%. Chest indrawing was significantly more (p=0.003) among 52(46.43%) cases who demonstrated positive radiological findings with sensitivity 63.46% (95% CI = 48.96% to 76.37%). There was no statistically significant difference of fever, cough and fast breathing between radiograph positive and negative cases. Chest indrawing was significantly more in radiograph positive cases. The results highlighted the importance of adoption of positive radiograph of WHO guideline to identify pneumonia.

Postnatal Support Strategies for Improving Rates of Exclusive Breastfeeding in Case of Caesarean Baby.

Despite awarness of the many advantages of breast feeding exclusive breastfeeding (EBF) rate is still lower than recommended practice and the rate is less in case of caesarean baby. In an effort towards achieving better breast feeding practices, UNICEF and WHO launched the baby friendly hospital initiative in 1991 to ensure that all maternity facilities support mothers in making the best choice about feeding. The implementation of effective programs improves rates of short and long term exclusive breast feeding even in case of caesarean baby. The objective of present study was to investigate whether postnatal support improves the rate of exclusive breast feeding in case of caesarean baby compared with usual hospital care. This was a longitudinal study over one and half year period, from April 2009 to October 2011 done in Combined Military Hospital in Mymensingh. A total of 565 pregnant women were included this study. Primary outcome was early establishment of breast feeding after caesarean section. Secondary outcome was exclusive breast feeding at discharge from hospital, two weeks and six weeks after caesarean section delivery. Early establishment of breast feeding within one hour after caesarean section was higher in postnatal support group than usual care group (70.29% vs. 57.14%). Rates of exclusive breastfeeding in the postnatal support strategies group were significantly higher when compared with those who received usual hospital care at discharge (89.13% vs. 75.94%, p=0.004), at 2 weeks (85.51% vs. 53.38%, p<0.001) and at 6 weeks (74.64% vs. 38.35%, p<0.001). Postnatal lactation support, as single intervention based in hospital significantly improves rates of exclusive breast feeding.

Drosophila HtrA2 is dispensable for apoptosis but acts downstream of PINK1 independently from Parkin.

High temperature requirement A2 (HtrA2/Omi) is a mitochondrial protease that exhibits proapoptotic and cell-protective properties and has been linked to Parkinson's disease (PD). Impaired mitochondrial function is a common trait in PD patients, and is likely to play a significant role in pathogenesis of parkinsonism, but the molecular mechanisms remain poorly understood. Genetic studies in Drosophila have provided valuable insight into the function of other PD-linked genes, in particular PINK1 and parkin, and their role in maintaining mitochondrial integrity. Recently, HtrA2 was shown to be phosphorylated in a PINK1-dependent manner, suggesting it might act in the PINK1 pathway. Here, we describe the characterization of mutations in Drosophila HtrA2, and genetic analysis of its function with PINK1 and parkin. Interestingly, we find HtrA2 appears to be dispensable for developmental or stress-induced apoptosis. In addition, we found HtrA2 mutants share some phenotypic similarities with parkin and PINK1 mutants, suggesting that it may function in maintaining mitochondrial integrity. Our genetic interaction studies, including analysis of double-mutant combinations and epistasis experiments, suggest HtrA2 acts downstream of PINK1 but in a pathway parallel to Parkin.
