Introduction
Despite the recent advancements in the management of Complete Heart Block (CHB), the aetiology of CHB is still idiopathic in most of the cases. Our study explores this hitherto untouched aspect of complete heart block.
Purpose
We aimed to assess the aetiological profile of Complete Heart Block patients in our study.
Methods
The study population consisted of 60 patients with complete heart block aged between 30 to 80 years, attending as an inpatient in ER. Oxidative stress was measured by serum MDA, serum GSH, serum Catalase activity and serum SOD activity. Antioxidant activity was obtained by measuring the levels of serum total antioxidant capacity. Inflammatory stress was measured by IL-5 and TNF-alpha levels. These values were compared to 30 healthy controls with no prior history of smoking and diabetes mellitus.
Results
The mean age of the patient was 62.48 ± 7.98 years and the gender distribution was 37 males and 23 females out of 60 patients. The mean value of serum MDA (ng/mL) in cases is 1451.26 ± 206.32, and in controls, the mean value is 1197.98 ± 234.71 (p=<0.001). The mean value of serum GSH (mcg/mL) in cases is 46.982 ± 18.613, and in controls, the mean value is 54.155 ± 10.762 (p=0.027). The mean value of serum Catalase Activity (U/min/mg protein) in cases is 10.763 ± 4.038 and in controls, the mean value is 19.878 ± 7.787 (p=0.003). The mean value of serum SOD Activity (U/g) in cases is 24.950 ± 5.4565, and in controls, the mean value is 46.214 ± 14.6309 (p=0.891). The mean value of serum Total Antioxidant Capacity (U/mL) in cases is 5.546 ± 0.620 and in controls, the mean value is 8.346 ± 2.781 (p=0.025). The mean value of serum IL-5 (pg/mL) in cases is 481.442 ± 28.8995, and in controls, the mean value is 67.347 ± 20.445 (p<0.001). The mean value of serum TNF-ALFA (pg/mL) in cases is 196.741 ± 73.771, and in controls, the mean value is 144.530 ± 42.599 (p= 0.081).
Conclusions
During a complete heart block, SOD (p=0.891), CAT (p=0.003), GSH (p=0.027) and total antioxidant (TAOC) (p=0.025) were significantly decreased in cases, compared to healthy controls, thus suggesting that the elevated levels of oxidative free radicals causes endothelial dysfunctioning. The increase in ROS was observed by a highly significant increase of malondialdehyde (MDA) (p=<0.001) showing high ROS-mediated tissue damage. Besides damage by oxidative stress, our study suggests that there are certain inflammatory markers like TNF-α and IL-5 that actively participate in causing heart block. There was a significant increase in the concentration of IL-5 (p<0.001) in the cases as compared to the controls.

Background
Morphological features of neointimal tissue play a pivotal role in the pathophysiology of In-Stent Restenosis (ISR) after percutaneous coronary intervention, hence understanding these features and patterns is crucial.
Purpose
The present study was designed to qualitatively and quantitatively assess neointimal characteristics of lesions using OCT in patients presenting with ISR.
Methods
This was a single-center, prospective, observational study performed between 1st August 2020 and 30th December 2021 at a tertiary-care center in India. Patients diagnosed with stable angina and acute coronary syndrome with post-procedural angiographically documented restenosis (>50%) were included. Qualitative and quantitative assessment of neointimal hyperplasia patterns was performed using OCT.
Results
A total of 34 patients with ISR were studied. Neointimal hyperplasia was classified as (i) homogenous group (n=18) and (ii) non-homogenous group (n=16). As many as 14 (77.8%) diabetics belonged to the homogenous group. Predominant plaque characteristics such as neoatherosclerosis, cholesterol crystals, and calcium were documented in 14 (77.8%), 12 (66.7%), and 11 (61.1%) patients in the homogenous group and in 10 (62.5%), 10 (62.5%), and 9 (56.2%) patients in the non-homogenous group, respectively. Unexpanded stent struts were identified in 11 (61.1%) and 11 (68.8%) patients in the homogenous and non-homogenous groups, respectively. Mean strut thickness was 93.73 ± 31.03 µm and 83.54 ± 18.0 µm, ISR was 72.50 ± 15.93% and 65.37 ± 21.69%, the neointimal thickness was 588.06 ± 167.82 mm and 666.25 ± 218.05 mm, and neointimal hyperplasia was 54.54 ± 11.23% and 59.26 ± 8.86% in the homogenous and non-homogenous groups, respectively.
Conclusion
Neoatherosclerosis and stent underexpansion was predominantly observed in our study, which was in contrast to most of the existing literature [1,2,3], and only diabetes was found to be significantly associated with homogenous neointimal hyperplasia, irrespective of the generation of the stent.

Abstract
Air quality is directly associated with the health of society. So, it becomes essential to forecast air pollution, which assumes an imperative part in air pollution warnings and control. A time-series simulation approach was adapted for the forecasting of monthly mean ambient air pollutants (PM2.5, O3, NO2) concentration and Aerosol Optical Depth (AOD) at an urban traffic site (Mathura Road, CSIR-CRRI) in New Delhi, India. Satellite-based aerosol loading (AOD550) retrieved from the Terra MODIS (Collection 6) enhanced Deep Blue (DB) algorithm was used for further analysis. The analysis considered the average monthly mean concentration of air pollutants and AOD between 2012-2017 and, simulates the concentrations of PM2.5, O3, NO2, and AOD for the same period and then forecasts air quality for the years 2020-2023. The forecasted results were validated with 24 months of in-situ and satellite data from 2018-to and 2019. In the year 2020, observed and simulated results are in lower agreement due to the shutdown of anthropogenic activities to combat pandemic situations. Otherwise, modeled and forecasted results are in good harmony with the in-situ and satellite observations. The results also signify that the time series Autoregressive Integrated Moving Average (ARIMA) modeling approach can be an effective and simple tool for air pollution simulation and future forecast. The results are evocative concerning the forecast of near future aerosol loading information and will also be profound to address the problems.

Abstract
BACKGROUND: India has the highest prevalence of multidrug-resistant TB (MDR-TB) globally. Vitamin D deficiency is potentially an important risk factor for MDR-TB.METHODS: We conducted a case-control study of 90 newly diagnosed adult MDR-TB cases, 180 household controls and 82 non-household controls in Mumbai, India. Serum 25-hydroxyvitamin D (25(OH)D), anthropometry, clinical status and history, dietary data and sociodemographic data were collected from each participant. Interferon-gamma release assay (IGRA) was also performed in controls to assess latent TB. Multivariable regression was performed to estimate associations between 25(OH)D vs. case status and IGRA positivity.RESULTS: Mean participant age was 33.8 ± 12.0 years; 72.8% had 25(OH)D <20 ng/ml. Mean 25(OH)D was significantly (P < 0.05) lower in cases (12.5 ± 7.9) than both household (17.5 ± 11.2) and non-household controls (16.4 ± 9.1). In multivariable models, 25(OH)D concentration was inversely associated with MDR-TB case status among cases and household controls (OR 0.95 per 1 ng/ml, 95% CI 0.92-0.99; P = 0.015), and among cases and non-household controls (OR 0.94 per 1 ng/ml, 95% CI 0.89-1.00; P = 0.033); 53.6% of controls were IGRA-positive. 25(OH)D status was not associated with IGRA positivity.CONCLUSION: Vitamin D status was independently associated with MDR-TB case status. Research should evaluate the effectiveness of vitamin D supplementation in prevention and adjunctive treatment of MDR-TB.

Abstract
Study question
What is the incidence of sperm DNA damage in men with normal semen analyses attending for initial fertility investigation?
Summary answer
Half of men (54%) attending for infertilty investigation had a normal semen analysis of which a third (32%) of these had abnormal sperm DNA.
What is known already
Conventional semen analysis assesses sperm concentration, motility, and morphology but with a high degree of biological variability. Around 25% of men are given a diagnosis of unexplained infertility by normal semen analysis. The World Health Organisation (WHO) stated in 2021 that ‘clinically there is a growing awareness that chromosomal anomalies and gene mutations underlie a diverse spectrum of male infertility,’ so now recommends that sperm DNA is determined as an extended analysis. Sperm DNA damage occurs more often in infertile men and DNA damage is associated with recurrent pregnancy loss and decreased live birth rates following fertility treatment.
Study design, size, duration
A prospective cohort study of men attending a secondary fertility clinic were offered a standard semen analysis plus sperm DNA fragmentation using SpermComet technology. UK IRAS ethical approval was obtained. Men attending were given a patient information leaflet at their first appointment. The study duration was 6 months. In total, 142 men were recruited out of a possible maximum of 409 attendees.
Participants/materials, setting, methods
Participants included men who had been referred as a couple to a secondary level infertility clinic for an initial assessment. Information leaflets were either posted to them prior to their first appointment or given to them at the initial nurse-led consultation. Those who subsequently contacted our research team re-attended for a sperm analysis and an aliquot was cryopreserved and sent in weekly batches to Examen (Northern Ireland) for SpermComet DNA fragmentation assessment.
Main results and the role of chance
Between May and November 2021, there were 409 attendees of whom 142 consented to the study.
Sperm DNA quality for the participants was assessed and reported as average, low and high DNA damage as a percentage compared with clinical thresholds used by Examen from their sperm bank of 63 fertile sperm donors who had recently achieved clinical pregnancies.
Of the 142 recruited, 77 men (54%) attending for initial investigations had normospermia assessed against the WHO criteria, so were initially classified as unexplained. Of these, 25 (32%) had abnormal sperm DNA values. The average comet score was 39.7% +/-1.3, low comet score was 37.8% +/- 4.4 and high comet score was 17.0% +/-2.0. These values were all significantly outside ( p < 0.001) of the fertile parameters from 63 fertile donors used by Examen (fertile range: average <26%%, low >74% and high <4%).
Our results suggest that up to a third of men reported to have normospermia will have DNA damaged sperm. This is important to consider before labelling a couple as 'unexplained'. Knowing the male's sperm DNA fragmentation assessment would allow for further discussion and exploration of lifestyle and dietary advice.
Limitations, reasons for caution
During the study period, not all attendees agreed to participate as it required an additional hospital visit. In this single site study, men have not yet been followed up for future fertility outcome such as natural conception and need or success of assisted conception.
Wider implications of the findings
Sperm DNA damage was found in a third of men who would previously have been classified as fertile and offered no further investigations or treatment to improve their sperm quality. Thus, this tool could be a useful adjunct to semen analysis to guide these couples’ future treatment pathways.

Abstract
OBJECTIVES This study aims to determine the impact of yoga as an adjunct to standard therapy versus standard therapy alone on the symptomatic burden in patients with recurrent vasovagal syncope (VVS). BACKGROUND There is a significant reduction in the quality of life (QoL) of patients with recurrent VVS. Existing management therapies have been largely ineffective. Recent trials have demonstrated the efficacy of yoga in diseases with autonomic imbalance, suggesting its possible utility in VVS. METHODS Patients with recurrent VVS were randomized to receive either a specialized yoga training program in addition to current guideline-based therapy (intervention arm, group 1) or current guideline-based therapy alone (control arm, group 2). The primary outcome was a composite of the number of episodes of syncope and presyncope at 12 months. Secondary outcomes included QoL assessment by World Health Organization Quality of Life Brief Field questionnaire (WHOQoL-BREF) scores and Syncope Functional Status Questionnaire scores at 12 months, head up tilt test, and heart rate variability at 6 weeks. RESULTS A total of 55 patients underwent randomization. The mean number of syncopal or presyncopal events at 12 months was 0.7 ± 0.7 in the intervention arm compared to 2.52 ± 1.93 in the control arm (P < 0.01). In the intervention arm, 13 (43.3%) patients remained free of events versus 4 (16.0%) patients in the control arm (P = 0.02). QoL at 12 months showed significant improvement of all Syncope Functional Status Questionnaire scores and 2 domains of WHOQoL-BREF scores (P < 0.05). CONCLUSIONS Yoga as adjunctive therapy is superior to standard therapy alone in reducing the symptomatic burden and improving QoL in patients with recurrent VVS.

Abstract
Abstract
Background
Intravenous flecainide is used to stress Atrio-ventricular (AV) conduction in patients (pts) with a history of syncope & bifascicular (Bi-Fasc) block. Role of oral flecainide is unclear.
Objective
To assess effect of oral Flecainide on infra-Hisian AV conduction in patients with symptomatic Bi-Fasc block.
Methods
Pts presenting with syncope & Bi-Fasc block without advanced AVCD on ECG, 24 hr holter or treadmill exercise test were taken. Those with history suggestive of reflex syncope & positive tilt test were excluded. Remaining underwent electro-physiological (EP) study. Pts with HV interval >100ms or intra/infra-Hisian block at rest or incremental pacing were subjected to PPI. Remaining received oral Flacanide 5 mg/kg (max 300 mg) & EP study was repeated after ½ hr, 1 hr, 2 hrs and 3 hrs. Primary end-point was HV ≥100ms or infra/intra-Hisian type IIB or III block.
Results
Of 41 pts enrolled for study, 28 patients (mean age 60.0 yrs, mean LVEF 60.7%) were eligible for EP Study. Basal PR interval was 185.8±47.4 ms & mean QRS width was 130.6±18.65 ms. On EP study, 4 (14.3%) with resting HV >100 ms & 6 (21.4%) with HV >100 ms on incremental pacing underwent PPI.
Out of remaining 18 pts who were given flecainide, 11 (66.1%) achieved primary endpoint (HV >100 ms in 6, infra-hisian IIB in 2 and 2:1 block in 3 patients). At mean follow up of 6.5 months, 13 (59.1%) out of 22 with PPI had mean 59.1% VP & none of 6 remaining patients had any symptom.
Conclusion
Oral Flecainide significantly increases the diagnostic yield of EP study in patients with symptomatic bi-fasc block.

Abstract
The N-methyl-d-aspartate receptors (NMDARs) are ionotropic ligand gated channels that are highly permeable to calcium ions. In insects, NMDARs are associated with glutamatergic neurotransmission governing diverse physiological and biological processes like vitellogenesis and ovarian development. Therefore, NMDAR may act as attractive target for insect pest control. In present study, we performed structural and functional characterization of NMDARs in Bemisia tabaci, a highly invasive crop pest and potent virus vector. We identified that NMDAR consists of three subunits each encoded by single gene in whiteflies which are highly conserved among different insect orders. Expression analysis suggests that subunit 1 (BtNR1) and subunit 2 (BtNR2) are the main functional units. External supplementation of NMDAR ligand or BtNRs silencing was lethal to insects, which suggested that NMDAR function is highly balanced in whiteflies.

Abstract
Spinning black holes in the centres of galaxies can release powerful magnetised jets. When the jets are observed at angles of less than a few degrees to the line-of-sight, they are called blazars, showing variable non-thermal emission across the electromagnetic spectrum from radio waves to gamma rays. It is commonly believed that shock waves are responsible for this dissipation of jet energy. Here we show that gamma-ray observations of the blazar 3C 279 with the space-borne telescope Fermi-LAT reveal a characteristic peak-in-peak variability pattern on time scales of minutes expected if the particle acceleration is instead due to relativistic magnetic reconnection. The absence of gamma-ray pair attenuation shows that particle acceleration takes place at a distance of ten thousand gravitational radii from the black hole where the fluid dynamical kink instability drives plasma turbulence. Blazars show variable non-thermal emission across the electromagnetic spectrum from radio waves to gamma rays. Here, the authors show blazar 3C 279 reveals a characteristic peak-in-peak variability pattern on time scales of minutes if particle acceleration is due to relativistic magnetic reconnection.

Abstract
The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used with other cosmic-ray species to understand cosmic-ray production and propagation in the Galaxy. For instance, low-energy antideuterons would provide a "smoking gun" signature of dark matter annihilation or decay, essentially free of astrophysical background. Studies in recent years have emphasized that models for cosmic-ray antideuterons must be considered together with the abundant cosmic antiprotons and any potential observation of antihelium. Therefore, a second dedicated Antideuteron Workshop was organized at UCLA in March 2019, bringing together a community of theorists and experimentalists to review the status of current observations of cosmic-ray antinuclei, the theoretical work towards understanding these signatures, and the potential of upcoming measurements to illuminate ongoing controversies. This review aims to synthesize this recent work and present implications for the upcoming decade of antinuclei observations and searches. This includes discussion of a possible dark matter signature in the AMS-02 antiproton spectrum, the most recent limits from BESS Polar-II on the cosmic antideuteron flux, and reports of candidate antihelium events by AMS-02; recent collider and cosmic-ray measurements relevant for antinuclei production models; the state of cosmic-ray transport models in light of AMS-02 and Voyager data; and the prospects for upcoming experiments, such as GAPS. This provides a roadmap for progress on cosmic antinuclei signatures of dark matter in the coming years.

Abstract
Serum prostatic specific antigen (PSA) and serum testosterone levels share an undefined relationship with each other, with many conflicting studies showing both positive and negative correlation between them. Our aim was to assess association between serum PSA and serum testosterone in healthy men with normal testosterone levels and men with partial androgen deficiency (PADAM). A cross sectional study was conducted at a teaching hospital setting where serum testosterone and aging male symptom scale (AMS) scores along with PSA were studied in 255 men (> 50 years) with and without PADAM. Mean total testosterone and serum PSA was 9.35 ± 1.33 nmol/L, 1.96 ± 0.76 ng/mL in males with PADAM and 15.30 ± 1.95 nmol/L, 1.85 ± 0.73 ng/mL respectively in males without PADAM. No significant relationship was observed between serum PSA and serum testosterone levels among healthy males irrespective of PADAM in the study population. We suggest, there is no need to adjust PSA values for biopsy decisions according to testosterone levels.

Abstract
Hydrogen is considered as an ideal and sustainable energy carrier because of its high energy density and carbon-free combustion. Electrochemical water splitting is the only solution for uninterrupted, scalable, and sustainable production of hydrogen without carbon emission. However, a large-scale hydrogen production through electrochemical water splitting depends on the availability of earth-abundant electrocatalysts and a suitable electrolyte medium. In this article, we demonstrate that hydrogen evolution reaction (HER) performance of electrocatalytic materials can be controlled by their surface functionalization and selection of a suitable electrolyte solution. Here, we report syntheses of few-layered MoS2 nanosheets, NiO nanoparticles (NPs), and multiwalled carbon nanotubes (MWCNTs) using scalable production methods from earth-abundant materials. Magnetic measurements of as-produced electrocatalyst materials demonstrate that MoS2 nanoflakes are diamagnetic, whereas surface-functionalized MoS2 and its composite with carbon nanotubes have strong ferromagnetism. The HER performance of the few-layered pristine MoS2 nanoflakes, MoS2/NiO NPs, and MoS2/NiO NPs/MWCNT nanocomposite electrocatalysts are studied in acidic and alkaline media. For bare MoS2, the values of overpotential (η10) in alkaline and acidic media are 0.45 and 0.54 V, respectively. Similarly, the values of current density at 0.5 V overpotential are 27 and 6.2 mA/cm2 in alkaline and acidic media, respectively. The surface functionalization acts adversely in the both alkaline and acidic media. MoS2 nanosheets functionalized with NiO NPs also demonstrated excellent performance for oxygen evolution reaction with anodic current of ~60 mA/cm2 and Tafel slope of 78 mVdec-1 in alkaline medium.

Abstract
We aimed to review the contributions by Indian researchers to the subspecialty of skeletal dysplasias (SDs). Literature search using specific keywords in PubMed was performed to retrieve all the published literature on SDs as on July 6, 2017. All published literature on SDs wherein at least one author was from an Indian institute was included. Publications were grouped into different categories based on the major emphasis of the research paper. Five hundred and forty publications in English language were retrieved and categorized into five different groups. The publications were categorized as reports based on: (i) phenotypes (n = 437), (ii) mutations (n = 51), (iii) novel genes (n = 9), (iv) therapeutic interventions (n = 31), and (v) reviews (n = 12). Most of the publications were single-patient case reports describing the clinical and radiological features of the patients affected with SDs (n = 352). We enlisted all the significant Indian contributions. We have also highlighted the reports in which Indians have contributed to discovery of new genes and phenotypes. This review highlights the substantial Indian contributions to SD research, which is poised to reach even greater heights given the size and structure of our population, technological advances, and expanding national and international collaborations.

Abstract
Objective The National Family Health Survey‐4 in India provided the first nationally representative estimates of hysterectomy among women aged 15–49. This paper aims to examine the national and state‐level age‐specific prevalence of hysterectomy, individual and household level factors associated with the procedure, and state‐level indicators that may explain variation across states. Design Cross‐sectional, nationally representative household survey. Setting National Family Health Survey was conducted across all Indian states and union territories between 2015 and 2016. Population The survey covered 699 686 women between the ages of 15 and 49 years. Methods Descriptive analyses and multivariate logistic regression. Main outcome measures Women who reported ever having a hysterectomy and age at hysterectomy. Results Age‐specific prevalence of hysterectomy was 0.36% (0.33,0.39) among women aged 15‐29; 3.59% (3.45,3.74) among women aged 30‐39; and 9.20% (8.94,9.46) among women 40‐49 years. There was considerable variation in prevalence by state. Four states reported age‐specific prevalence similar to high‐income settings. Approximately two‐thirds of hysterectomies were conducted in private facilities, with similar patterns across age groups. At the national level, higher age and parity (at least two children); not having had formal schooling; rural residence (adjusted odds ratio [AOR] 1.36; 95% CI 1.27,1.45; P < 0.01) and higher wealth status were associated with higher odds of hysterectomy. Previously sterilised women had lower odds (AOR 0.64; 95% CI 0.61,0,68; P < 0.01) of reporting hysterectomy. Exploratory analyses suggest state‐level factors associated with prevalence of hysterectomy include caesarean section, female illiteracy, and women's employment. Conclusions Hysterectomy patterns among women aged 15–49 in India indicate the critical need to ensure treatment options for gynaecological morbidity and to address hysterectomy among young women in particular. Funding This study was part of the RASTA initiative of the Population Council's India country office under the Evidence Project supported by USAID. Tweetable abstract Hysterectomy patterns in India highlight the need for alternatives to treat gynaecological morbidity among younger women. Hysterectomy patterns in India highlight the need for alternatives to treat gynaecological morbidity among younger women.

Abstract
Acute limb ischemia and peripheral vascular disease (PVD) are unusual presentations of polyarteritis nodosa (PAN). Here, we present a case with PVD of both lower limbs leading to foot claudication. Digital subtraction angiography showed narrowing, irregularity, and occlusion of both lower limb arteries with no involvement of the abdomen visceral arteries. Based on significant weight loss, diastolic blood pressure >90 mmHg, myalgia, testicular pain, and angiographic abnormalities in medium-sized arteries, he was diagnosed as having PAN. He was treated with corticosteroid and bolus intravenous cyclophosphamide following which he had prompt and near-complete recovery of the symptoms without any tissue loss.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) due to Hepatitis B viral (HBV) infection is a major cause in Asia-Pacific countries. Its early detection is of paramount importance using a marker having both sensitivity and specificity. The present study promises diagnostic and prognostic markers by the identification of site-specific glycoforms on Haptoglobin (Hp) using LC-MS/MS and lectin ELISA in liver diseased conditions in HBV infection. METHODS Three groups of patients: chronic, liver cirrhosis and HCC with HBV infection along with controls were enrolled. Hp was purified using affinity column chromatography and, peptide sequence, N-glycosylation site, glycan composition and glycoforms were identified using mass spectrometry. Quantitative lectin ELISA was used to measure levels of fucosylation on Hp in liver diseases due to HBV. RESULTS Hp levels were significantly lower in HCC when compared with Non-HCC cases (p < .05). Fucosylated glycoforms were significantly increased at site Asn184, Asn207 and Asn211 in liver diseased stages versus controls. A significant association was observed between the Fuc-Hp/Hp Elisa index and, advanced liver disease stages and controls using lectin Elisa (p < .001). CONCLUSION Quantitation of fucosylation levels on Hp protein using Lectin ELISA may be useful glycobiomarker either alone or in combination (AFP + DCP + FucHp; AUC = 0.94) in HBV HCC diagnosis in clinical practice.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

Abstract
GALAXIES is an in-vacuum undulator hard X-ray micro-focused beamline dedicated to the study of the electronic structure of materials with high energy resolution using both photoelectron spectroscopy and inelastic X-ray scattering and under both non-resonant (NR-IXS) and resonant (RIXS) conditions. Due to the penetrating power of hard X-rays and the `photon-in/photon-out' technique, the sample environment is not a limitation. Materials under extreme conditions, for example in diamond anvil cells or catalysis chambers, thus constitute a major research direction. Here, the design and performance of the inelastic X-ray scattering end-station that operates in the energy range from ∼4 keV up to 12 keV is reported, and its capabilities are highlighted using a selection of data taken from recently performed experiments. The ability to scan `on the fly' the incident and scattered/emitted X-ray energies, and the sample position enables fast data collection and high experimental throughput. A diamond X-ray transmission phase retarder, which can be used to generate circularly polarized light, will also be discussed in the light of the recent RIXS-MCD approach.

Abstract
BACKGROUND Chronic hepatitis C infection is a major cause for liver failure and liver cancer and can be treated with highly effective all oral directly acting antiviral (DAA) drugs. Generic versions of these DAAs are available in India. METHOD This was an open-label, single-center, prospective, nonrandomized observational study for the comparative safety and efficacy of generic versus brand name sofosbuvir with ribavirin therapy for chronic hepatitis C infection (all genotypes). Between December 2014 and December 2015, 66 patients received either generic sofosbuvir (400mg) or brand name SOLVALDI (400mg) with weight based ribavirin for 24 weeks in a single multispecialty hospital in Mumbai. Monitoring viral loads and safety labs was performed as per national guidelines. RESULTS Sustained virologic response was 72.4% versus 75.7% (p=0.78) among patients treated with generics and SOVALDI, respectively. At 4 weeks on-treatment, approximately 90% of patients from both groups had undetectable or below the lower limit of quantification. Change in hemoglobin was comparable in both groups (p=0.26). CONCLUSION Generic versions of sofosbuvir reported in this study are safe and efficacious to treat hepatitis C. However, bioequivalency studies of all generic DAAs need to be performed before wider use of such drugs for the treatment of hepatitis C.

Abstract
The location and/or type of variants in FLNB result in a spectrum of osteochondrodysplasias ranging from mild forms, like spondylocarpotarsal synostosis syndrome and Larsen syndrome, to severe perinatal lethal forms, such as atelosteogenesis I and III and Boomerang dysplasia. Spondylocarpotarsal synostosis syndrome is characterized by disproportionate short stature, vertebral anomalies and fusion of carpal and tarsal bones. Biallelic loss-of-function variants in FLNB are known to cause spondylocarpotarsal synostosis syndrome and 9 families and 9 pathogenic variants have been reported so far. We report clinical features of 10 additional patients from 7 families with spondylocarpotarsal synostosis syndrome due to 7 novel deleterious variants in FLNB, thus expanding the clinical and molecular repertoire of spondylocarpotarsal synostosis syndrome. Our report validates key clinical (fused thoracic vertebrae and carpal and tarsal coalition) and molecular (truncating variants in FLNB) characteristics of this condition.

Abstract
Until 2014, pegylated interferon plus ribavirin was the recommended standard of care for the treatment of chronic hepatitis C virus (HCV) infection in India. This open-label phase 3b study, conducted across 14 sites in India between 31 March 2014 and 30 November 2015, evaluated the efficacy and safety of sofosbuvir plus ribavirin therapy among treatment-naïve patients with chronic genotype 1 or 3 HCV infection. A total of 117 patients with genotype 1 or 3 HCV infection were randomized 1:1 to receive sofosbuvir 400 mg and weight-based ribavirin (1000 or 1200 mg) daily for 16 or 24 weeks. Among those with genotype 1 infection, the primary efficacy endpoint of sustained virologic response at 12 weeks post-treatment (SVR12) was reported in 90% (95% confidence intervals [CI], 73-98) and 96% (95% CI, 82-100) of patients following 16 and 24 weeks of treatment, respectively. For patients with genotype 3 infection, SVR12 rates were 100% (95% CI, 88-100) and 93% (95% CI, 78-99) after 16 and 24 weeks of therapy, respectively. Adverse events, most of which were mild or moderate in severity, occurred in 69% and 57% of patients receiving 16 and 24 weeks of treatment, respectively. The most common treatment-emergent adverse events were asthenia, headache and cough. Only one patient in the 24-week group discontinued treatment with sofosbuvir during this study. Overall, sofosbuvir plus ribavirin therapy achieved SVR12 rates ≥90% and was well tolerated among treatment-naïve patients with chronic genotype 1 or 3 HCV infection in India.

Abstract
Gut microflora and dysbiosis as an environmental factor has been linked to the pathogenesis of enthesitis-related arthritis (JIA-ERA); thus, we performed a proof-of-concept study of probiotics to modulate the gut-flora and study the effects on immune and clinical parameters of children having JIA-ERA. Forty-six children with active JIA-ERA were randomized to placebo or probiotic therapy along with non-steroidal anti-inflammatory drugs (NSAIDs) for 12 weeks. Patients were assessed using a six-point composite disease activity index (mJSpADA) based on morning stiffness, joint count, enthesitis count, sacroiliitis/inflammatory back pain, uveitis and erythrocyte sedimentation rate/C-reactive protein (ESR/CRP). Frequencies of T helper type 1 (Th1), Th2, Th17 and regulatory T cells in blood were measured using flow cytometry. Serum cytokines interferon (IFN)-γ, interleukin (IL)-4, IL-17, IL-10, tumour necrosis factor (TNF)-α and IL-6 were measured by cytokine bead array using flow cytometer. The average age of 46 children (44 boys) was 15 ± 2.5 years and duration of disease was 3.5 ± 3 years. There was no significant difference in improvement in mJSpADA between the two groups (P = 0·16). Serum IL-6 levels showed a decrease (P < 0·05) in the probiotic-group. Th2 cell frequency (P < 0·05) and serum IL-10 levels (P < 0·01) showed an increase in the placebo group, but again the probiotic use did not show a significant change in immune parameters when compared to the placebo. Adverse effects among the probiotic and placebo groups were diarrhea (36 versus 45%), abdominal pain (9 versus 20%), minor infections (4·5 versus 20%) and flatulence (23 versus 15%), respectively. Thus, we can conclude that probiotic therapy in JIA-ERA children is well tolerated, but failed to show any significant immune or clinical effects over NSAID therapy.

Abstract
Steel syndrome is a rare disorder of the skeleton characterized by facial dysmorphism, short stature, carpal coalition, dislocated radial heads, bilateral hip dislocation and vertical talus. Homozygous variants in COL27A1 were reported in an extending family from Puerto Rico. Here, we report a 5-year-old girl from a non-consanguineous family with facial dysmorphism, short stature, carpal coalition, dislocation of radial heads, bilateral hip dislocation, scoliosis and vertical talus. Exome sequencing identified 2 novel compound heterozygous variants c.521_528del (p.(Cys174Serfs*34)) and c.2119C>T (p.(Arg707*)) in COL27A1 in this child and the parents were heterozygous carriers. We hence report the second molecularly proven case of Steel syndrome and the first case to be reported among non-Puerto Rican population. Our report further validates the role of COL27A1 mutations in causation of Steel syndrome.

Abstract
In Asia, enthesitis-related arthritis (ERA) is the most frequent category of juvenile idiopathic arthritis. ERA has a strong association with human leucocyte antigen (HLA)-B27 and subclinical gut inflammation. In an HLA-B27 transgenic rat model, the presence of Bacteroides bacteria in the gut appears to cause spondyloarthropathy (SpA). Thus, we studied gut microbiota in children with ERA. Stool specimens from 33 patients with ERA and 14 age-matched healthy controls were studied; none had any gastrointestinal symptom, or had received a drug known to affect gut motility or microbiota in the preceding 6 weeks. From each specimen, a cDNA library for the V3 region of bacterial 16S rRNA was subjected to high-throughput, massively parallel sequencing. Relationship of the specimens was studied using principal co-ordinate analysis (PCoA), and abundances of various bacterial taxa and alpha diversity were compared between groups. In eight patients, a repeat faecal specimen was studied after 12 weeks of probiotic therapy. The 55 specimens yielded a median (range) of 397 315 (102 093-1 502 380) high-quality reads each. In PCoA, gut microbiota from ERA showed a wider dispersion than those from controls. In patients, families Bacteroidaceae and Enterobacteriaceae were more abundant and Prevotellaceae were less abundant than in controls. Also, genera Bacteroides, Entercoccus and Klebsiella were over-represented and genus Prevotella was under-represented in ERA patients. Probiotic therapy led to a non-significant increase in Prevotellaceae. Patients with ERA have a dysbiosis in the gut, with increased abundance of Bacteroides and reduction of Prevotella. Probiotic supplementation in a subset of patients did not reverse these changes significantly.

Abstract
Pancreatic trauma is relatively uncommon and although the surgical management is in many cases comparatively simple, occasionally complex technical surgery is required. Early diagnosis is paramount, although this remains difficult. The challenge of pancreatic trauma is compounded by a high incidence of associated injuries to adjoining organs and major vascular structures that may require damage control surgery and delayed definitive repair and add to the high frequency of postoperative complications, morbidity and mortality.

Abstract
In this study the effect of dimethylsulfoxide (DMSO) radii on the droplets and on the required non-ionic surfactant volume for preparing water-in-oil microemulsions (MEs) was investigated. Five series of MEs were prepared either with the aid of isopropylpalmitate or medium chain triglycerides (MCTG) as continuous phases. The MEs were stabilized via either Tween80 or Span20 or a mixture of both. A mixture of water:DMSO (W:DMSO) with different ratios formed the colloidal phase of the first four MEs series. Only DMSO was used as colloidal phase of the fifth series. Dynamic light scattering (DLS) was used for measuring the radii of the droplets of MEs. The results showed that the consumed volumes of the surfactants were related to the W:DMSO ratio and the surfactant type. Moreover, the consumed surfactant volumes increased with decreasing radii of the droplets of the MEs. The MEs stabilized with Span20 had lower radii of the droplets (4-15 nm) than MEs stabilized by Tween80 (25-65 nm). It was evident that DMSO changed the interfacial tension which is reflected by changing the the volume of the surfactant consumed and by altering the droplets sizes. Consequently, DMSO acted as co-surfactant in stabilizing the MEs by reducing the required volumes of the surfactant which is important for reducing their toxicity.

Abstract
Intraflagellar transport (IFT) is vital for the functioning of primary cilia. Defects in several components of IFT complexes cause a spectrum of ciliopathies with variable involvement of skeleton, brain, eyes, ectoderm and kidneys. We examined a child from a consanguineous family who had short stature, narrow thorax, short hands and feet, postaxial polydactyly of hands, pigmentary retinopathy, small teeth and skeletal dysplasia. The clinical phenotype of the child shows significant overlap with cranioectodermal dysplasia type I (Sensenbrenner syndrome). Whole-exome sequencing revealed a homozygous nonsense variant p.R142* in IFT52 encoding an IFT-B core complex protein as the probable cause of her condition. This is the first report of a human disease associated with IFT52.

Abstract
Cutaneous manifestations of visceral carcinomas are scarce, occurring in around 0.7-12% of internal malignancies. Lung cancer is one of the most common sources of skin metastasis, particularly in male patients. We present a case of cutaneous metastasis in a man with concurrent lung lesions and a previously treated colorectal carcinoma. Immunohistochemistry markers for both skin and lung lesions were strongly positive for carcinoembryonic antigen and cytokeratin 20, suggesting an intestinal primary tumour. However, colonoscopy excluded new and metastatic bowel lesions. After multidisciplinary team meetings, which reviewed the clinical, radiological and immunohistochemistry findings, it was concluded to be a non-small cell lung cancer with skin metastasis. This case presented an interesting diagnostic challenge, and highlighted the importance of cross-specialty liaison and investigation to reach the correct diagnosis.

Abstract
We set out to evaluate multiplex ligation dependent probe amplification (MLPA) as a tool for diagnosis and carrier detection in families with a dystrophinopathy. Fifty three Indian families with provisional diagnosis of Duchene muscular dystrophy or Becker muscular dystrophy were evaluated by MLPA and multiplex polymerase chain reaction (PCR). Sanger sequencing was used to analyze the entire gene in one patient. Mothers were tested for carrier status whenever possible. Molecular analysis of DMD gene by combining MLPA and multiplex PCR yielded a mutation detection rate of 62% (33/53). Deletions were detected in 27/53 (51%) cases, duplications in 5/53 (9%) cases, a small deletion one case and Sanger sequencing detected a nonsense mutation in one case. Mutation was not detected in 36% (19/53) cases. Fifty six percent of mothers (9/16) were found to be carriers. MLPA helped to refine the results of multiplex PCR testing in 22 patients (5 duplications, 16 deletions and one small deletion). We also describe a situation where a deletion of single exon on MLPA (but not detected by multiplex PCR) was actually due to a deletion of two nucleotides in the probe ligation site. MLPA appears to score over multiplex PCR in diagnosis and carrier detection, specifically by detecting deletions and duplications that are not detected by traditional multiplex PCR.

Abstract
The Gorkha earthquake (magnitude 7.8) on 25 April 2015 and later aftershocks struck South Asia, killing ~9000 people and damaging a large region. Supported by a large campaign of responsive satellite data acquisitions over the earthquake disaster zone, our team undertook a satellite image survey of the earthquakes' induced geohazards in Nepal and China and an assessment of the geomorphic, tectonic, and lithologic controls on quake-induced landslides. Timely analysis and communication aided response and recovery and informed decision-makers. We mapped 4312 coseismic and postseismic landslides. We also surveyed 491 glacier lakes for earthquake damage but found only nine landslide-impacted lakes and no visible satellite evidence of outbursts. Landslide densities correlate with slope, peak ground acceleration, surface downdrop, and specific metamorphic lithologies and large plutonic intrusions.

Abstract
Introduction: Sacrococcygeal teratomas (SCT) are the most common solid tumours in the neonatal period, originate from embryonic totipotent cells. Most of them are benign however some that present later in life and have major intra-pelvic component have greater malignant potential. Complete surgical excision provides an excellent prognosis. The aim of this study was to describe the clinical profile, age of presentation, sex distribution, diagnostic evaluation and management of children with a histological confirmed diagnosis of sacrococcygeal teratoma.Material and Methods: Patients with histological diagnosis of sacrococcygeal teratoma during a period from January 2011 to December 2012 were included in this retrospective study. Data collected included age of presentation, sex distribution, symptoms, associated anomalies, diagnostic evaluation, operative approach technique employed, tumour histology, operative complications and outcome.Results: Thirty six patients with diagnosis of sacrococcygeal teratoma were included in the study. Of these children, 58.33% were females and 41.66% were males. The median age at presentation was four days. 69.44% of patients presented during the neonatal period. 77.77% of patients presented with sacrococcygeal mass followed by lower abdominal mass in 11.11%. The tumour was resected by sacral approach in 27 patients and abdomino sacral approach in nine patients. Tumour was resectable in 34 patients and two had incomplete resection. Follow up duration varied from six months to 24 months.Conclusion: Sacrococcygeal teratomas represent a group of benign and malignant lesions of children. Neonates present with benign disease and aggressive lesions are seen as age progresses. Overall survival of SCT is high.J Nepal Paediatr Soc 2015;35(1):89-93

Abstract
Religious/spiritual (r/s) characteristics of physicians influence their attitude toward integrative medicine and spiritual care. Indonesia physicians collaborate with traditional, complementary, and alternative medicine (TCAM) professionals within modern healthcare system, while Indian physicians are not reported to do so. The aim of the study was to understand the r/s characteristics and their influence on Indian and Indonesian physicians' acceptance of TCAM/spirituality in modern healthcare system. An exploratory, pilot, cross-cultural, cross-sectional study, using Religion and Spirituality in Medicine, and Physician Perspectives (RSMPP) survey questionnaire, compared r/s characteristics and perspectives on integrative medicine of 169 physicians from two allopathic, Sweekar-Osmania University (Sweekar-OU), India, University of Airlanga (UNAIR), Indonesia, and a TCAM/Central Research Institute of Unani Medicine (CRIUM) institute from India. More physicians from UNAIR and CRIUM (89.1 %) described themselves as "very"/"moderately" religious, compared to 63.5 % Sweekar-OU (p = 0.0000). Greater number of (84.6 %) UNAIR physicians described themselves as "very" spiritual and also significantly high (p < 0.05) in intrinsic religiosity as compared to Sweekar-OU and TCAM physicians; 38.6 % of UNAIR and 32.6 % of CRIUM participants reported life-changing spiritual experiences in clinical settings as against 19.7 % of Sweekar-OU; 92.3 % of UNAIR, compared to CRIUM (78.3 %) and Sweekar-OU (62 %), felt comfortable attending to patients' spiritual needs, (p = 0.0001). Clinical comfort and not r/s characteristics of participants was the significant (p = 0.05) variable in full regression models, predictive of primary outcome criteria; "TCAM or r/s healing as complementary to allopathic treatment." In conclusion, mainstreaming TCAM into healthcare system may be an initial step toward both integrative medicine and also improving r/s care interventions by allopathic physicians.

Abstract
Background: Oral cancer is the sixth most common cancer in the world. P53 mutations are associated with the development of oral squamous cell carcinomas. This study is to determine the presence of p53 oncogene expression in cases of oral malignant, premalignant and benign lesions and to show association of p53 oncogene and lymph node enlargement in malignant lesion.Materials and Methods: Four to five micron-thick sections of formalin fixed, paraffin embedded biopsy material from various intra-oral sites of 50 patients were collected, in the series of 50 cases, 35 oral squamous cell carcinoma, 10 dysplastic lesions and 05 hyperplastic lesions were assessed for p53 expression. The tissue sections were immunohistochemically analyzed for the expression of p53 gene.Results: Out of 50; 22/35 (63%) cases of squamous cell carcinoma, 02/10 (20%) cases of dysplasia (20%), were positive for p53. Five hyperplastic lesions were negative for p53. The P53 protein was not identified in benign lesion.Conclusion: Results indicate that p53 over-expression is seen in oral squamous cell carcinomas. It is a significant marker of carcinogenesis and can be considered as an important marker for clinical evaluation, diagnosis as well as prognosis of disease.Journal of Pathology of Nepal (2015) Vol. 5, 747-751

Abstract
In Wireless Body Area Networks (WBAN) the energy consumption is dominated by sensing and communication. Previous Compressed Sensing (CS) based solutions to EEG tele-monitoring over WBAN's could only reduce the communication cost. In this work, we propose a matrix completion based formulation that can also reduce the energy consumption for sensing. We test our method with state-of-the-art CS based techniques and find that the reconstruction accuracy from our method is significantly better and that too at considerably less energy consumption. Our method is also tested for post-reconstruction signal classification where it outperforms previous CS based techniques. At the heart of the system is an Analog to Information Converter (AIC) implemented in 65nm CMOS technology. The pseudorandom clock generator enables random under-sampling and subsequent conversion by the 12-bit Successive Approximation Register Analog to Digital Converter (SAR ADC). AIC achieves a sample rate of 0.5 KS/s, an ENOB 9.54 bits, and consumes 108 nW from 1 V power supply.
