Abstract
OBJECTIVE To test the hypothesis that in neonates on mechanical ventilation, heart rate characteristics index (HRCi) can be combined with a clinical model for predicting extubation outcomes in neonates. STUDY DESIGN HRCi and clinical data for all intended intubation-extubation events (episodes) were retrospectively analyzed between June 2014 and January 2015. Each episode started 6 hours pre-extubation or at the time of primary intubation if ventilation duration was shorter than 6 hours (baseline). The episodes ended at 72 hours postextubation for successful extubations or at reintubation for failed extubations. Mean of 6 hourly epoch HRCi-scores (baseline) or fold-changes (postextubation) were analyzed. Results are expressed as medians (IQR) for continuous data and proportions for categorical data. Multivariable logistic regression mixed model was used for statistical analysis. RESULTS Sixty-six infants contributed to 96 episodes (18 failed extubations, 78 successful extubations) in the study. Failed extubations had significantly longer duration of ventilation (65.3 hours, 19.94-158.2 vs 38.4, 16.5-71.3) and more culture positive sepsis (33.3% vs 3.8%) than successful extubations. Baseline HRCi scores (1.68, 1.29-2.45 vs 0.95, 0.54-1.86) and postextubation epoch-1 fold changes (1.25, 0.94-1.55 vs 0.94, 0.82-1.11) were higher in failed extubations compared with successful extubations. Multivariable linear mixed-effects regression was used to create prediction models for success of extubation, using relevant variables. CONCLUSIONS The baseline and postextubation HRCi were significantly higher in neonates with extubation failure compared with those who succeeded. Models using HRCi and clinical variables to predict extubation success may add to the confidence of clinicians considering extubation.

Abstract
Purpose To establish an effective approach for diagnosis and treatment of hand ischemia in matured radiocephalic arteriovenous fistulae (AVF). Methods One hundred and fifty end-stage renal disease patients (4% of our practice) presented to our outpatient vascular access facility complaining of a range of symptoms including coldness, numbness and pain in the fingers indicative of ischemia due to steal syndrome. In 15 patients the symptoms of steal syndrome were limited to the fingers, sparing the hand. Physical examination was indicative of steal syndrome caused by shunting of blood from the ulnar artery via the palmar arch, away from the fingers and into the fistula. To confirm the diagnosis, angiography was performed which demonstrated retrograde flow in the distal radial artery (DRA), a hypertrophied palmar arch, and a patent hypertrophied ulnar artery. Ischemia was treated with DRA flow interruption. Transcatheter coil embolization of the DRA (10 patients) was preferred because it proved to be a quick, safe and effective technique. Whenever embolization was not possible ligation of the DRA was performed in accordance with accepted surgical literature (five patients). Results DRA flow interruption was effectively accomplished by either ligation or coil embolization in all cases. All patients had symptomatic improvement. Complete symptom resolution was experienced by 100% (10/10) of patients who received DRA embolization and by 3/5 patients who required ligation. The average follow-up period was 9 months. There were no complications during the procedure or during the follow-up period. Conclusion Diagnosis using physical examination, angiography and treatment with embolization or ligation of the DRA can be performed with great success in an outpatient setting.

Abstract
OBJECTIVE It is postulated that children with asthma who receive an interactive, comprehensive, culturally relevant education program would improve their asthma knowledge (AK), asthma control, and adherence compared with children receiving usual care. The aim of this study was to develop, implement, and evaluate the efficacy of a culturally relevant asthma education intervention for children with asthma and their parents in India. METHODS Children with asthma (7-12 years) and their parents were recruited from an outpatient clinic in a Chest Diseases Hospital in New Delhi, and were randomly assigned to either an intervention or usual care group. At baseline, outcome data collected included pediatric asthma caregiver quality of life (PACQL, primary outcome), AK, asthma control, adherence, inhaler technique, action plan ownership, and goal achievement. These data were collected again at 1 and 6 months after baseline. Outcomes were compared within and between groups using ANOVA techniques. RESULTS Forty parent-child pairs were recruited. Of these, 24 pairs of children with asthma and their parents received the educational intervention. The PACQL significantly improved from baseline to 6 months in the intervention (5.87 ± 0.94-7.00 ± 0.03) versus the usual care group (5.90 ± 0.52-6.34 ± 0.56) (P < 0.001). Other outcomes such as the parents' and child's AK, child's asthma control and inhaler technique were significantly improved in the intervention group across the study. All the participants possessed a written asthma action plan at the end of the intervention. Eighty-five goals were set by children with asthma across all the visits and were achieved by completion. CONCLUSION An asthma educator delivered interactive program simultaneously involving children with asthma and their parents, improved quality of life, empowered and promoted better self-management skills.

Abstract
A comprehensive investigation of magnetostriction optimization in Metglas 2605SA1 ribbons is performed to enhance magnetoelectric performance. We explore a range of annealing conditions to relieve remnant stress and align the magnetic domains in the Metglas, while minimizing unwanted crystallization. The magnetostriction coefficient, magnetoelectric coefficient, and magnetic domain alignment are correlated to optimize magnetoelectric performance. We report on direct magnetostriction observed by in-plane Doppler vibrometer and domain imagining using scanning electron microscopy with polarization analysis for a range of annealing conditions. We find that annealing in an oxygen-free environment at 400 °C for 30 min yields an optimal magnetoelectric coefficient, magnetostriction and magnetostriction coefficient. The optimized ribbons had a magnetostriction of 50.6 ± 0.2 μm m-1 and magnetoelectric coefficient of 79.3 ± 1.5 μm m-1 mT-1. The optimized Metglas 2605SA1 ribbons and PZT-5A (d31 mode) sensor achieves a magnetic noise floor of approximately 600 pT Hz-1/2 at 100 Hz and a magnetoelectric coefficient of 6.1 ± 0.03 MV m-1 T-1.

Abstract
BACKGROUND Extravasation injury, a complication commonly seen in the neonatal intensive care unit, can result in scarring with cosmetic and functional sequelae. A wide variety of treatments are available, including subcutaneous irrigation with saline (with or without hyaluronidase), liposuction, use of specific antidotes, topical applications, and normal wound care with dry or wet dressings. All such treatments aim to prevent or reduce the severity of complications. OBJECTIVES Primary objective To compare the efficacy and safety of saline irrigation or saline irrigation with prior hyaluronidase infiltration versus no intervention or normal wound care for tissue healing in neonates with extravasation injury. Secondary objectives To evaluate by subgroup analysis of controlled trials the influence of type of extravasate, timing of irrigation following extravasation, and postmenstrual age (PMA) of the neonate at the time of injury on outcomes and adverse effects.Specifically, we planned to perform subgroup analysis for the primary outcome, if appropriate, by examining:1. time to irrigation from identified extravasation injury (< 1 hour or ≥ 1 hour);2. type of extravasate (parenteral nutrition fluid or other fluids or medications);3. amount of saline used (< 500 mL or ≥ 500 mL); and4. PMA at injury (< 37 completed weeks or ≥ 37 completed weeks). SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1), MEDLINE via PubMed (1966 to 2 February 2017), Embase (1980 to 2 February 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 2 February 2017). We also searched clinical trial databases, conference proceedings, and reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. We used the Google Scholar search tool for reverse citations of relevant articles. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-randomised controlled trials comparing saline irrigation with or without hyaluronidase infiltration versus no intervention or normal wound care for the management of extravasation injury in neonates. DATA COLLECTION AND ANALYSIS Three review authors independently reviewed and identified articles for possible inclusion in this review. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS We found no eligible studies. Our search revealed 10 case reports or case series describing successful outcomes with different interventions for this condition. AUTHORS' CONCLUSIONS To date, no RCTs have examined the effects of saline irrigation with or without prior hyaluronidase infiltration for management of extravasation injury in neonates. Saline irrigation is frequently reported in the literature as an intervention for management of extravasation injury in neonates. Research should focus first on evaluating the efficacy and safety of this intervention through RCTs. It will also be important for investigators to determine effect size by examining the timing of the intervention, the nature of the infusate, and severity of injury at the time of intervention.

Abstract
INTRODUCTION Several studies in developed countries have shown association between indoor air pollution and asthma in children. The present research was undertaken to study this association at Delhi, India. MATERIAL AND METHODS This study took place at Delhi, capital of India. Eight locations based on the source of pollution such as industrial, residential and villages were included. Recording of the demographic profile and clinical examination of each child was conducted at their residence. Indoor SO₂, NO₂ and SPM (suspended particulate matter) levels were measured by using Handy Air Sampler (Low Volume Sampler). RESULTS A total of 3104 children were examined of which 60.3% were male and 39.7% were female. 32.4% children were exposed to environmental tobacco smoke. 31.5 % children's families were using biomass fuels for cooking. History of respiratory symptoms included cough (43.9%), phlegm production (21.9%), shortness of breath (19.3%) and wheezing (14.0%). 7.9% children were diagnosed as having asthma, which was highest in industrial areas (11.8%), followed by residential (7.5%) and village areas (3.9%). The mean indoor SO₂, NO₂ and SPM levels were 4.28 ± 4.61 mg/m³, 26.70 ± 17.72 mg/m³ and 722.0 ± 457.6 mg/m³ respectively. Indoor SPM was the highest in industrial area followed by residential area and urban village area. Indoor SPM level was significantly (p < 0.001) higher in the asthmatic children's houses. CONCLUSION This study suggests that industry plays an important role in increasing the concentration of indoor suspended particulate matter and occurrence of asthma in children in developing countries like India.

Abstract
Objective The recent availability of servo-controlled cooling equipment on transport makes it possible to commence active cooling at the referral unit for infants with hypoxic-ischemic encephalopathy. This study aimed to compare the temperature and transfer variables in passively and actively cooled babies. Study Design This is a retrospective cohort study comparing two groups-passively cooled (July 2011 to August 2012) versus actively cooled group (September 2012 to June 2013), following introduction of active hypothermia using servo-controlled cooling mattress by the London Neonatal Transfer Service (NTS). Results Seventy-six infants were passively cooled and 69 were actively cooled. There was a significant difference between the temperatures of the two groups at each point in the transfer episode: on arrival of NTS, during stabilization, during transfer, and at the receiving hospital. Median time to achieve target temperature was 30 (95% confidence interval [CI]: 23-37) minutes in actively cooled, significantly shorter in comparison to 130 (95% CI: 83-177) minutes in passively cooled babies. Of the 69 newborns, 62 (90%) had temperature within target range at receiving center in actively cooled group as compared with 30/76 (40%) in passively cooled group. Conclusion The use of active cooling during neonatal transfer achieves target temperature in a shorter period and maintains better temperature stability.

Abstract
OBJECTIVES (1) To detect cervical intraepithelial neoplasia (CIN) using Papanicolaou test (PAP test), visual tests (visual inspection after the application of acetic acid [VIA], visual inspection after the application of Lugol's iodine [VILI]), colposcopy, and biopsy. (2) To study the biomarker p16(INK4A) expression by immunostaining. MATERIALS AND METHODS Experimental study was conducted from November 2009 to April 2011. 1500 women were screened for cancer cervix using conventional PAP test, VIA, and VILI. Sensitivity, specificity, positive, and negative predictive values of these tests were calculated individually, sequentially, and in parallel. Women having positive results underwent colposcopy and biopsy if required. p16(INK4A) expression in biopsy samples was studied using immunohistochemistry. RESULTS All test positive cases (n = 235) underwent colposcopy. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PAP with atypical squamous cells of undetermined significance (ASCUS) as cut-off was 40%, 99.25%, 35.25%, and 99.39%; VIA was 60%, 93.06%, 8.03%, and 99.56% and VILI was 80%, 86.06%, 5.4%, and 99.76%, respectively. When PAP, VIA, and VILI were used in parallel sensitivity, specificity, PPV, and NPV improved to 100%, 85.18%, 6.38%, and 100%, respectively. Colposcopic abnormalities were detected in 83 and biopsy proven CIN in 15. p(16INK4A) expression was seen in eight of 15 CIN cases. CONCLUSIONS (1) PAP test and visual techniques are complementary. (2) p(16INK4A) expression was seen in majority of CIN 2 lesions suggesting a higher grade lesion.

Abstract
BACKGROUND Tuberculosis is a major public health problem. Almost 30% of cases of tuberculosis are known to be sputum smear negative. There is a diagnostic dilemma in such cases leading to inadvertent delays in management of these cases. The present study was planned to assess the role of bronchoscopy in immediate diagnosis of smear negative pulmonary tuberculosis. MATERIAL AND METHODS The present study is a retrospective analysis of 132 sputum smear negative tuberculosis suspects who underwent bronchoscopic evaluation during the period 2002-2013. The diagnosis of tuberculosis was based on the finding of bacilli in aspirate or in tissue biopsy or the demonstration of caseous necrosis on tissue biopsy. RESULTS The present study showed that bronchoscopy could lead to immediate, accurate diagnosis in 68.2% of suspected smear negative cases. Bronchial aspirate and bronchoalveolar lavage alone were diagnostic in 51.5% of such cases while tissue biopsy added to the yield in another 16.5% cases. CONCLUSIONS The results of the present study suggests an important place of bronchoscopy in immediate diagnosis of suspected smear negative tuberculosis, thus avoiding inadvertent delays in diagnosing and instituting appropriate treatment.

Abstract
INTRODUCTION The available data on the epidemiology of interstitial lung disease (ILD) from India is sparse. Hence, the present study was undertaken with the aim to analyse the demographic profile and clinical, radiological and pathological characteristics along with physiological parameters of various subgroups of ILD patients. MATERIAL AND METHODS We retrospectively studied 289 patients diagnosed with ILD during the years 2001-2013 at one of the respiratory units of Vallabhbhai Patel Chest Institute. RESULTS Mean age at presentation was 44.24 years; females comprised 54.68% of the patients. Prior to presentation at our centre, 14.84% patients had been treated with antituberculous therapy due to misdiagnosis of tuberculosis. In the pool of ILDs analysed, sarcoidosis (37.3%) was found to be the most common subgroup, followed by IPF (27.6%) and NSIP (25.6%). Cough (92.97%) was the most common presenting symptom; exertional dyspnoea was found in 79.2% of patients. Digital clubbing was commonest in IPF, found in 30% of patients. Significant desaturation on six-minute walk test was most frequenty seen (50%) in NSIP patients. The most common pattern on chest roentgenogram was reticular/reticulo-nodular pattern (80.2%) and on HRCT - interstitial fibrosis (49.9%). Mean of predicted total lung capacity (TLC) was 64.3%, the lowest being in the IPF group (58.88%). Mean of predicted DLCO was 50.56%, the lowest being in the IPF group (42.75%). The overall diagnostic yield of bronchoscopic biopsy was 83.04%, the highest yield being among sarcoidosis patients (96.29%). CONCLUSIONS We found sarcoidosis, IPF and NSIP to be the most common ILDs in northern India. ILDs are still frequently misdiagnosed as TB, and increased awareness, education and diagnostic facilities are required to diagnose ILDs at an early stage.

Abstract
Several new isotopes, ^{96}In, ^{94}Cd, ^{92}Ag, and ^{90}Pd, have been identified at the RIKEN Nishina Center. The study of proton drip-line nuclei in the vicinity of ^{100}Sn led to the discovery of new proton emitters ^{93}Ag and ^{89}Rh with half-lives in the submicrosecond range. The systematics of the half-lives of odd-Z nuclei with T_{z}=-1/2 toward ^{99}Sn shows a stabilizing effect of the Z=50 shell closure. Production cross sections for nuclei in the vicinity of ^{100}Sn measured at different energies and target thicknesses were compared to the cross sections calculated by epax taking into account contributions of secondary reactions in the primary target.

Abstract
Objective. Tobacco consumption continues to rise in India with about 34.6% of adult population being tobacco users. This study was done to evaluate the epidemiological profile of the tobacco users presenting to a Tobacco Cessation Centre (TCC) in Delhi. Methods. This is a retrospective observational study of subjects seen over a period of 10 years (2001-2010) at TCC of Vallabhbhai Patel Chest Institute, University of Delhi, Delhi, India. Information from a structured questionnaire filled by all tobacco users was pooled and analysed. Results. Of a total of 4493 subjects seen in the TCC, 4370 (97.3%) were males. 2704 (60.2%) subjects were smokers and remaining were users of smokeless tobacco. The highest number of subjects attending the clinic was between the age of 31 to 40 years. The mean age of starting tobacco use was 21 years. 2518 subjects started tobacco use due to “peer group pressure”, while family history of tobacco use was observed in 2912 subjects. 3065 number of subjects attending the clinic were without any co-morbidity. Conclusions. Most of the subjects started tobacco use at a young age between 11 to 20 years. Peer pressure was the most common reason for initiation (56%). Most of the subjects (68.2%) had no co-morbidity. The present study observed that tobacco users probably want to quit smoking not only because of the consequences of co-morbidities but also because of the realisation of later harmful effects of continuing smoking.

Abstract
In the present study, rumen microbial groups, i.e. total rumen microbes (TRM), total anaerobic fungi (TAF), avicel enriched bacteria (AEB) and neutral detergent fibre enriched bacteria (NEB) were evaluated for wheat straw (WS) degradability and different fermentation parameters in vitro. Highest WS degradation was shown for TRM, followed by TAF, NEB and least by AEB. Similar patterns were observed with total gas production and short chain fatty acid profiles. Overall, TAF emerged as the most potent individual microbial group. In order to enhance the fibrolytic and rumen fermentation potential of TAF, we evaluated 18 plant feed additives in vitro. Among these, six plant additives namely Albizia lebbeck, Alstonia scholaris, Bacopa monnieri, Lawsonia inermis, Psidium guajava and Terminalia arjuna considerably improved WS degradation by TAF. Further evaluation showed A. lebbeck as best feed additive. The study revealed that TAF plays a significant role in WS degradation and their fibrolytic activities can be improved by inclusion of A. lebbeck in fermentation medium. Further studies are warranted to elucidate its active constituents, effect on fungal population and in vivo potential in animal system.

Abstract
PURPOSE Enteric fever is a major public health problem in developing countries like India. An early and accurate diagnosis is necessary for a prompt and effective treatment. We have evaluated the diagnostic accuracy of two Rapid Salmonella-IgM tests (Typhidot-IgM and Enteroscreen-IgM) as compared to blood culture in rapid and early diagnosis of enteric fever. MATERIALS AND METHODS A total of 2,699 patients' serum samples were tested by Rapid Salmonella-IgM tests and blood culture. Patients were divided into two groups. Test group - patients with enteric fever and blood culture positives for Salmonella Typhi; and three types of Controls, i.e. patients with non-enteric fever illnesses, normal healthy controls and patients positive for S. Paratyphi- A. In addition to this we have also evaluated the significance of positive Salmonella-IgM tests among blood culture-negative cases. RESULTS The overall sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the Typhidot-IgM test and Enteroscreen-IgM test considering blood culture as gold standard were 97.29% and 88.13%, 97.40% and 87.83%, 98.18% and 92.03%, 96.15% and 82.27%, respectively. Typhidot-IgM test was found to be significantly more sensitive and specific as compared to Enteroscreen-IgM. Among blood culture-negative patients, Rapid Salmonella-IgM tests detected 72.25% additional cases of enteric fever. Although the Rapid Salmonella-IgM tests are meant to diagnose S. Typhi only, but these tests detect S. Paratyphi- A also. Thirty-eight patients who were blood culture-positive for S. Paratyphi- A were also positive by Rapid Salmonella-IgM tests. CONCLUSION Rapid Salmonella-IgM tests offer an advantage of increased sensitivity, rapidity, early diagnosis and simplicity over blood culture.
