Abstract
This work aims to efficiently capture CO2 on two-dimensional (2D) nanostructures for effective cleaning of our atmosphere and purification of exhausts coming from fuel engines. Here, we have performed extensive first principles calculations based on density functional theory (DFT) to investigate the interaction of CO2 on a recently synthesized ZnO monolayer (ZnO-ML) in its pure, defected and functionalized form. A series of rigorous calculations yielded the most preferential binding configurations of the CO2 gas molecule on a ZnO-ML. It is observed that the substitution of one oxygen atom with boron, carbon and nitrogen on the ZnO monolayer resulted into enhanced CO2 adsorption. Our calculations show an enriched adsorption of CO2 on the ZnO-ML when substituting with foreign atoms like B, C and N. The improved adsorption energy of CO2 on ZnO suggests the ZnO-ML could be a promising candidate for future CO2 capture.

Abstract
Hypertension is common in children with chronic kidney disease (CKD) and is a major determinant of CKD progression. Ambulatory blood pressure monitoring (ABPM) has been proposed to be better in detecting hypertension as compared to casual blood pressure (CBP). This study aims to study the usefulness of ABPM in detecting masked hypertension, evaluating the adequacy of blood pressure (BP) control and predicting left ventricular hypertrophy (LVH) amongst children with CKD. A prospective cross-sectional study of 46 children with stage 3–5 CKD was conducted at the Pediatric Nephrology department of a tertiary hospital in South India. All children underwent CBP, ABPM and an echocardiography. Results were categorized as normal BP; confirmed hypertension; masked hypertension and white coat hypertension. Out of 46 children studied, 11 were undergoing dialysis. While 39.1% children had stage 3 and 4 CKD each, 21.7% had stage 5 CKD. Masked hypertension was detected in 19.6% and 21.7% had confirmed hypertension. Thirty-four (73.9%) children were already receiving antihypertensive medication. In these, CBP was elevated in 23.5% and ABP in 47%. Among children with hypertension as defined by ABPM, LVH was detected in 32.2%. We found that higher the number of abnormal ABPM indices (assessed by BP Index, nocturnal dipping and BP Load) higher the likelihood of LVH (P = 0.046). ABPM is better in detecting hypertension and monitoring adequacy of treatment in children with CKD. The high prevalence of masked hypertension and its association with LVH supports early echocardiography and ambulatory BP monitoring to evaluate cardiovascular risks in this population.

Abstract
Introduction: Home mechanical ventilation (HMV) can prolong survival and improve quality of life. The objectives were to review the challenges, clinical conditions and outcome of children who were discharged from the hospital on respiratory support.Material and Methods: Twenty four patients, who were electively discharged from PICU and had received home ventilatory support for more than 15 days, were enrolled over 11 year study period. Patients were followed up monthly, for two years, for ventilatory requirements, any problems encountered during previous month and for any complication.Results: Twenty four patients with a median age of 3.5 years were discharged home with ventilatory support. HMV was started in 2001 at our hospital. Patents received home ventilation for a median period 5.4 months. Twenty (83.3%) patients received invasive mechanical ventilation via tracheostomy and four (16.7%) patients received non-invasive mechanical ventilation. Twelve (50%) patients received ventilatory support for more than 20 hrs a day and twelve (50%) patients received only during sleep. On follow up for two years for each patient, twenty (83.3%) patients successfully came off from ventilatory support while, two (8.3%) patients died and two (8.3%) lost to follow-up.Conclusion: HMV can be safely applied in selected children with CRF after providing adequate training to the care givers. For its more efficient use, we need to have good social support and medical assistance which can be extended to their homes to meet their complete health care needs.J Nepal Paediatr Soc 2015;35(1):85-88

Abstract
Owing to its high energy density, the potential of hydrogen (H2) as an energy carrier has been immense, however its storage remains a big obstacle and calls for an efficient storage medium. By means of density functional theory (DFT) in spin polarized generalized gradient approximation (GGA), we have investigated the structural, electronic and hydrogen storage properties of a light alkali metal (Li, Na) functionalized fluorographene monolayer (FG). Metal adatoms bind to the FG with significantly high binding energy, much higher than their cohesive energies, which helps to achieve a uniform distribution of metal adatoms on the monolayer and consequently ensure reversibility. Due to a difference of electronegativities, each metal adatom transfers a substantial amount of its charge to the FG monolayer and attains a partial positive state, which facilitates the adsorption of multiple H2 molecules around the adatoms by electrostatic as well as van der Waals interactions. To get a better description of H2 adsorption energies with metal-doped systems, we have also performed calculations using van der Waals corrections. For both the functionalized systems, the results indicate a reasonably high H2 storage capacity with H2 adsorption energies falling into the range for the practical applications.

Abstract
Sweet's syndrome is characterized by erythematous tender nodules and plaques over face and extremities. Fever, leukocytosis with neutrophilia, and a neutrophilic infiltrate in the dermis are characteristic features. Neutrophilic dermatosis of dorsal hands is a rare localized variant of Sweet's syndrome occurring predominantly over dorsa of hands. Various degrees of vascular damage may be observed on histopathology of these lesions. Both Sweet's syndrome and its dorsal hand variant have been reported in association with malignancies, inflammatory bowel diseases, and drugs. We report a patient with neutrophilic dermatoses of dorsal hands associated with erythema nodosum. He showed an excellent response to corticosteroids and dapsone.

Abstract
A versatile heterodyne Doppler Backscattering (DBS) system is used to measure density fluctuation levels (in the wavenumber range kρs ≤ 50), and the toroidal E × B flow velocity in the C-2 Field-Reversed Configuration (FRC). Six tunable frequencies in three waveguide bands (26 GHz ≤ f ≤ 90 GHz) are launched using monostatic beam optics, via a quasi-optical beam combiner/polarizer and an adjustable parabolic focusing mirror (inside the vacuum enclosure) achieving Gaussian beam spot sizes of 3-5.5 cm at the X/O-mode cutoff. The DBS system covers plasma densities of 0.8 × 10(13) ≤ ne ≤ 1 × 10(14) cm(-3), and provides access to the FRC core (up to the field null) and across the FRC separatrix into the scrape-off layer plasma.

Abstract
Background The purpose of this open-label study was to correlate the auscultation findings of ZargisCardioscan™ with the echocardiographic findings in our patient population who were referred for echocardiography so as to investigate and ensure the validity of this technology before instituting its applicability in community health events among rural Indian population. Materials and Methods This was a double blinded prospective correlation study in outpatients presenting for echocardiography. Methods: One hundred patients, who had presented for echocardiography at Cardiology Center of an academic university hospital in rural India, were enrolled in this double blinded prospective correlation study. Principal investigator who is a community medicine physician performed the auscultation of patients’ hearts in sitting position. Subsequently, the ZargisCardioscan™ software was used to analyze the heart sounds auscultated by the 3M™ Littmann® Model 3200 stethoscope. Thereafter, the scheduled echocardiography for which the patient had presented to hospital was performed by co-investigator cardiologist who was blinded to the results obtained by the ZargisCardioscan™.Finally, all these data were statistically analyzed by blinded investigator for the presence of correlation between the two modalities. Results The most important finding was the high 90s negative predictive values when the stethoscope-software combination was used for auscultation and analysis of heart murmurs. Additionally, presence of isolated systolic murmurs had higher incidence of appreciable significant valvular lesions and presence of isolated diastolic murmurs primarily had underlying minimal-mild regurgitant valvular lesion, if any. The Bland-Altman Plot confirmed good correlation between stethoscope-echocardiography findings. Conclusion Stethoscope-software combination, 3M™ Littmann® Model 3200 and ZargisCardioscan™, accurately predicts the absence of valvular heart disease on echocardiography.DOI: http://dx.doi.org/10.3126/nje.v4i3.10665 Nepal Journal of Epidemiology 2014; 4(3): 363-369

Abstract
In 2011, bi-directional screening for tuberculosis (TB) and diabetes mellitus (DM) was recommended by the World Health Organization (WHO), although how best to implement the activity was not clear. In India, with early engagement of national programme managers and all important stakeholders, a countrywide, multicentre operational research (OR) project was designed in October 2011 and completed in 2012. The results led to a rapid national policy decision to routinely screen all TB patients for DM in September 2012. The process, experience and enablers of implementing this unique and successful collaborative model of operational research are presented.

Abstract
OBJECTIVE Anatomical changes during radiotherapy (RT) might introduce discrepancies between planned and delivered doses. This study evaluates the need for adaptive treatment in lung cancer RT. METHODS 15 patients with non-small-cell lung cancer, undergoing radical RT with or without concurrent chemotherapy, consecutively underwent planning CT scans at baseline and after 44-46 Gy. Target volumes were delineated on both scans. Phase I delivered 44-46 Gy to the initial planning target volume (PTV). Two Phase II plans for 16-20 Gy were developed on initial and mid-treatment scans, the treatment being delivered with the mid-treatment plan. The second CT structure set was fused with the initial scan data set using dose wash. Volumetric and dosimetric changes in target volumes and critical structures were assessed. RESULTS There was significant reduction in primary gross tumour volume (34.00%; p = 0.02) and PTV (34.70%; p < 0.01) in the second scan. In Plan 2, delivering the same dose to the initial PTV would have resulted in a significantly higher dose to the lung PTV (V20, 52.18%; V5, 21.76%; mean, 23.93%), contralateral lung (mean, 29.43%), heart (V10, 81.47%; V5, 56.62%; mean, 35.21%) and spinal cord (maximum dose, 37.53%). CONCLUSION Treatment replanning can account for anatomical changes during RT and thereby enable better normal tissue sparing, while allowing radical target doses with the possibility of maximizing local control. ADVANCES IN KNOWLEDGE This study supports the sparse dosimetric data regarding the quantitative tumour volume reduction, re-emphasizing the need for adaptive replanning for minimizing normal tissue toxicity without compromising local control, and adds to the existing body of literature.

Abstract
SETTING Newly diagnosed pulmonary tuberculosis (PTB) patients starting treatment under the Revised National Tuberculosis Control Programme (RNTCP) in a North Indian city. OBJECTIVE To quantify impairment in health-related quality of life (HRQoL) of PTB patients at the time of diagnosis and during treatment, and to assess the utility of these assessments as a measure of outcome under programme conditions. DESIGN HRQoL was assessed using the Hindi version of the 26-item World Health Organization Quality of Life (WHOQOL-BREF) scale at the start and end of the intensive phase and at completion of treatment. Four domain scores-physical, psychological, social relationships and environment-were calculated and compared between groups, based on different patient and disease characteristics. Psychometric evaluation was conducted by assessing acceptability, validity and responsiveness of the questionnaire. RESULTS A total of 2654 HRQoL assessments were performed among 1034 patients. Domain scores were generally better among men, urban residents, younger patients, patients with higher socio-economic status and those with less severe disease. The WHOQOL-BREF demonstrated good psychometric properties, and domain scores improved with treatment. Residual HRQoL impairment was noted in some patients even at treatment completion. CONCLUSION HRQoL is impaired in patients with PTB, and improves rapidly and significantly with programme-based treatment. HRQoL assessment can be used as an adjunct outcome measure for patients treated by the RNTCP.

Abstract
OBJECTIVE To describe the clinical outcomes of histologically confirmed adenocarcinoma in situ (AIS) of the cervix treated with cervical conization. MATERIALS AND METHODS A retrospective chart review of patients with histologically confirmed AIS from July 1998 to February 2011 included 52 patients. The rates of residual disease in subsequent excisions, the clinical recurrence rate, the average disease-free interval, and risk of progression to adenocarcinoma were described. The clinical outcomes of patients treated with cold knife cone (CKC) and loop electrosurgical excisional procedure (LEEP) were compared. RESULTS Fifteen LEEPs and 37 CKC procedures were performed as initial treatment and 26 patients (50%) had positive margins. There was no significant difference in rate of positive margins between LEEP and CKC (40% vs. 54%, respectively. p = 0.55). LEEPs and CKCs resulted in similar volumes of cervical tissue resected (4.98 cm3 vs. 5.04 cm3, p = 0.40). Of patients with positive margins, ten underwent immediate hysterectomy, six underwent a second cone biopsy, seven were managed expectantly, and four were lost to follow up. Residual AIS was found in 47% (eight of 17) of repeat cone biopsy and hysterectomy specimens performed for positive cone margins. Of the 26 patients with negative cone margins, no residual or recurrent disease was found after an average follow-up of 32 months. CONCLUSIONS A positive surgical margin was associated with residual disease in 47% of patients with AIS treated with conization. No patient with negative cone margins had recurrent or progressive disease. Cervical conization with negative margins appears to be a safe treatment option for patients with AIS but requires further investigation. CKC and LEEP were equally efficacious treatments in our study population.

Abstract
BACKGROUND Sarcoidosis and tuberculosis closely resemble each other and Mycobacterium tuberculosis has been implicated as a causative agent for sarcoidosis. Herein we explore the socio-demographic features of patients with sarcoidosis vis-a-vis tuberculosis. METHODOLOGY In a prospective case-control design, we studied hundred patients each of newly diagnosed sarcoidosis, bacteriologically confirmed pulmonary tuberculosis and healthy controls. Socio-demographic profile was recorded on a standardized questionnaire. Information about tobacco smoking, exposure to environmental tobacco smoke (ETS) and cooking fuels was also collected. Various parameters were compared among the three groups. RESULTS Compared to tuberculosis, patients with sarcoidosis were elder, had better body mass index (BMI), higher urban residence (OR 2.19, 95% CI: 1.02-4.69), were better educated (ORs 8.50 to 74.25 for different categories), had higher per capita income (OR 13.33; 95% CI: 6.79-26.19) and belonged to better overall socio-economic status (SES) (ORs 8.57-195.0 for different categories). All these differences were also significant when sarcoidosis patients were compared to healthy controls albeit to a lesser degree. Tobacco smoking, ETS exposure and use of fossil/biomass fuels for cooking were more commonly seen in TB patients. In the multivariate analysis, as compared to TB or controls, sarcoidosis patients had higher odds for a better SES after adjusting for age, gender, BMI, religion, smoking, ETS exposure and cooking fuel. CONCLUSIONS Patients with sarcoidosis are likely to be better educated and more affluent compared to those with tuberculosis and healthy controls and this can be useful in clinical differential diagnosis of the two conditions in populations with high prevalence of TB.
