Abstract
Introduction Peripheral nerve injuries (PNIs) remain an important health problem. PNIs mostly affect young men as this age group is mostly involved in road traffic accidents and other injuries at workplace. PNI can occur from foreign bodies like metal chips while working in industries using lathe machines. Among PNI's, injuries to the ulnar nerve, the brachial plexus and the median nerve are the most frequent lesions encountered. Materials and methods This presentation is on a series of 18 cases of nerve injuries among industrial workers located from finger level up to the arm excluding the brachial plexus due to metallic foreign bodies entering while operating lathe machines over a period of two years with patients being followed-up over a one year period. Results Mean age in this series was 31.3 years with age range 16-40 years and all were males. Two patients had more than one nerve involvement and one patient had associated vascular injury. All the patients showed functional improvement. Most common nerve injured was median nerve. Most common site for nerve injury was forearm. Combined lesions most commonly involved the ulnar and median nerves. Conclusion Social cost of traumatic peripheral nerve injuries is significant since it has a higher incidence in young, previously healthy, and economically active people.

Diagnostic performance of saliva RT-PCR test as a diagnostic tool and its utility in the detection of SARS-CoV-2 shedding with different patient characteristics: Prospective observational study. Indian J Med Microbiol 2024; 47:100490. [PMID: 37890412 DOI: 10.1016/j.ijmmb.2023.100490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 09/28/2023] [Accepted: 09/29/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Salivary shedding of SARS-CoV-2 is a known entity and its role has been established in transmission of the disease. The present study was performed to evaluate the duration of viral shedding in saliva in COVID-19 patients and its variation among symptomatic and asymptomatic patients with or without co-morbidities. METHODS The present prospective observational study was conducted at the COVID-19 care hospital associated with primary to tertiary care in New Delhi, India. A total of 124 COVID-19 confirmed cases enrolled in two phases (January-March 2021; April-June 2021) who consented for 48hrly saliva and nasopharyngeal swab (NPS) specimens till discharge from the hospital for SARS-CoV-2 detection were included. The specimens obtained were tested for SARS-CoV-2 by Real-Time PCR. RESULTS The sensitivity and the specificity of RT-PCR on saliva were 81.7 % and 85.0 %, respectively. The sensitivity of saliva-based PCR was comparable in symptomatic and asymptomatic patients (81.6 % vs 82.1 %). The sensitivity of saliva-based PCR markedly increased in the second phase of enrollment as compared to the first phase (92.6 % vs 78.5 %) indicating higher level of salivary shedding by the delta variant of SARS-CoV-2. The sensitivity of PCR on saliva was the highest up to day seven of illness. The median duration of RNA shedding in saliva was comparable among the symptomatic and asymptomatic patients. The severity of the disease was not associated with the duration of SARS-CoV-2 shedding in saliva. CONCLUSIONS SARS-CoV-2 shedding in saliva continued till seven days in large number of patients including asymptomatic patients. Saliva is non-inferior to NPS specimen in the diagnosis of SARS-CoV-2. Saliva specimen is recommended as a good alternate to NPS for SARS-CoV-2 testing.

Abstract
A systematic mapping of natural absorbed dose rate was carried out to assess the existing exposure situation in India. The mammoth nationwide survey covered the entire terrestrial region of the country comprising of 45127 sampling grids (grid size 36 km2) with more than 100,000 data points. The data was processed using Geographic Information System. This study is based on established national and international approaches to provide linkage with conventional geochemical mapping of soil. Majority (93%) of the absorbed dose rate data was collected using handheld radiation survey meters and remaining were measured using environmental Thermo Luminescent Dosimeters. The mean absorbed dose rate of the entire country including several mineralized regions, was found to be 96 ± 21 nGy/h. The median, Geometric Mean and Geometric Standard Deviation values of absorbed dose rate were 94, 94 and 1.2 nGy/h, respectively. Among the High Background Radiation Areas of the country, absorbed dose rate varied from 700 to 9562 nGy/h in Karunagappally area of Kollam district, Kerala. The absorbed dose rate in the present nationwide study is comparable with the global database.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2022; 9:8-15. [PMID: 36259751 DOI: 10.1093/ehjqcco/qcac067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 10/11/2022] [Indexed: 11/12/2022]
Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
Abstract
Background
Percutaneous coronary intervention (PCI) of bifurcation lesions is associated with higher rates of adverse events, and currently it is unclear whether PCI or coronary artery bypass grafting (CABG) is the safer treatment for these patients at very long-term follow up.
Objectives
To investigate the impact of bifurcation lesions on observed all-cause 10-year mortality in the SYNTAX trial.
Methods
In the SYNTAX Extended Survival study, 10-year observed mortality was compared among four groups: (a) presence of ≥1 bifurcation lesion and treatment with PCI (n=649), (b) no bifurcation lesion and treatment with PCI (n=248), (c) presence of ≥1 bifurcation lesion and treatment with CABG (n=651), and (d) no bifurcation lesion and treatment with CABG (n=239).
Results
Compared to patients without bifurcations, those with bifurcation lesion(s) treated with PCI had a significantly higher risk of all-cause death (19.8% vs 30.1%; HR: 1.55, 95% CI: 1.12 to 2.14; p=0.007), whereas following CABG, mortality was similar in patients with or without bifurcation lesion(s) (23.3% vs 23.0%; HR: 0.81, 95% CI: 0.59 to 1.12; p=0.207). (Figure1) There was a significant interaction between bifurcation lesion(s) and treatment arm (p for interaction=0.006).
In PCI patients, at 5-years there was no significant difference in mortality between 1- vs 2-stent techniques, whereas at 10-years, a 2-stent technique was associated with higher mortality (33.3% vs 25.9%; HR: 1.51, 95% CI: 1.06 to 2.14; p=0.021, Figure2).
Conclusions
Bifurcation lesion(s) require special attention from the heart team discussion, considering the higher 10-year all-cause mortality associated with PCI. Careful evaluation of bifurcation lesion complexity may be helpful in decision-making.

Abstract
Abstract
Background
To compare the observed and individual predicted mortalities according to the SYNTAX score II 2020 (SSII-2020) in the all-comers SYNTAX population, and retrospectively assess the appropriateness of revascularization with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with three vessel disease (3VD) and/or left main disease (LMCAD).
Methods
Internal and external validation of the SSII-2020 to predict 10-year all-cause death was performed in the respective randomized and registry SYNTAX populations. Differences in individual predicted mortalities following CABG or PCI were ranked and displayed with the observed mortalities. The proportions of screened patients deriving a survival benefit from CABG or PCI were determined retrospectively.
Results
A total of 2602 participants (as-treated population) were included in the randomized and registry cohorts. In the randomized cohort, all-cause mortality at 10 years, as an average treatment effect, was 23.8% (199/865) with CABG and 28.6% (249/901) with PCI, with a differential survival benefit of 4.6% (95% CI: 0.58% to 8.7%, log-rank p value=0.023). In the CABG and PCI registries, mortalities were 27.8% (167/644) and 55.4% (99/192), respectively. Calibration and discrimination of the SSII-2020 was helpful in CABG and PCI patients in the randomized and registry cohorts. In the PCI registry, the SSII-2020 underestimated mortality since specific comorbidities that entail high mortality are not included in the formula (C-index: 0.72, intercept: 0.38, slope: 0.66), whilst in the CABG registry, it predicted mortality with a helpful calibration and discrimination (C-index: 0.70, intercept: 0.00, slope: 0.76). The proportions of patients with a predicted survival benefit following CABG and PCI were respectively 78.3% (1383/1766) and 21.7% (383/1766) in the randomized cohort, and 82.4% (2143/2602) and 17.7% (459/2602) in the whole SYNTAX trial population.
Conclusion
In the randomized and registry cohort of this all-comers population with 3VD and/or LMCAD, there was reasonable agreement between the individual predicted and observed mortalities after CABG or PCI, such that the predicted 10-year survival benefit might be helpful in determining the appropriateness of each modality of revascularization.

Abstract
Abstract
Background
Regurgitation following TAVR impacts all-cause mortality. So far, no quantitative comparison of regurgitation by the same core lab has been performed among the various commercially available transcatheter heart valves (THV) We aimed to compare quantitative angiographic aortic regurgitation (AR) of 11 different types of THVs.
Method
This is a multicentre retrospective corelab pooled analysis of aortograms from 2704 consecutive patients treated with 11 different THV devices. Analysis was done by quantitative videodensitometric aortography (LVOT-AR), which is an objective, accurate, and reproducible tool for assessment of AR following TAVR. This method relies on time density changes in contrast medium after injection in the ascending aorta and its regurgitation (and subsequent density increase) in the LVOT. The ratio between the areas under the two-time density curves of these regions quantifies the AR in absolute percentage. The valves evaluated include ACURATE neo2 (n=120), Lotus (n=546), Myval (n=108), VitaFlow (n=105), Evolut PRO (n=95), SAPIEN 3 (n=397), Evolut R (n=295), SAPIEN XT (n=239), ACURATE neo (n=120), Venus-A (n=113) and CoreValve (n=532). Stratification of continuous variable regurgitation into categorical variables was performed according to the following pre-determined threshold criteria: 1) none/trace regurgitation (LVOT-AR<6%); 2) mild (6%≤ LVOT-AR ≤17%); and 3) moderate or severe (LVOT-AR >17%).
Results
The addition of anti PVR sealing features to the new generations ACURATE neo2 THV proved to be effective in reduction the incidence of significant PVR In comparison with the first generation ACURATE neo.
Myval, VitaFlow and Venus-A THVs are showing promising results.
Although the incidence of moderate/severe AR has regressed over time with new generations of THVs, the incidence of mild AR is still prominent with all THVs still exhibiting mild AR with an incidence ranging between 30% and 50% with the exception of the Lotus valve that had an 19% incidence of mild AR
Conclusion
ACURATE neo2 had the lowest severe/moderate percentage of AR showing significant improvements in comparison to ACURATE neo. Myval, VitaFlow and Venus-A are promising options in the THV armamentarium. These results should be confirmed in prospective randomized, head-to-head comparisons between THVs.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BACKGROUND Identification of residual disease in patients with localized non-small cell lung cancer (NSCLC) following treatment with curative intent holds promise to identify patients at risk of relapse. New methods can detect circulating tumour DNA (ctDNA) in plasma to fractional concentrations as low as a few parts per million, and clinical evidence is required to inform their use. PATIENTS AND METHODS We analyzed 363 serial plasma samples from 88 patients with early-stage NSCLC (48.9%/28.4%/22.7% at stage I/II/III), predominantly adenocarcinomas (62.5%), treated with curative intent by surgery (n = 61), surgery and adjuvant chemotherapy/radiotherapy (n = 8), or chemoradiotherapy (n = 19). Tumour exome sequencing identified somatic mutations and plasma was analyzed using patient-specific RaDaR™ assays with up to 48 amplicons targeting tumour-specific variants unique to each patient. RESULTS ctDNA was detected before treatment in 24%, 77% and 87% of patients with stage I, II and III disease, respectively, and in 26% of all longitudinal samples. The median tumour fraction detected was 0.042%, with 63% of samples <0.1% and 36% of samples <0.01%. ctDNA detection had clinical specificity >98.5% and preceded clinical detection of recurrence of the primary tumour by a median of 212.5 days. ctDNA was detected after treatment in 18/28 (64.3%) of patients who had clinical recurrence of their primary tumour. Detection within the landmark timepoint 2 weeks to 4 months after treatment end occurred in 17% of patients, and was associated with shorter recurrence-free survival [hazard ratio (HR): 14.8, P <0.00001] and overall survival (HR: 5.48, P <0.0003). ctDNA was detected 1-3 days after surgery in 25% of patients yet was not associated with disease recurrence. Detection before treatment was associated with shorter overall survival and recurrence-free survival (HR: 2.97 and 3.14, P values 0.01 and 0.003, respectively). CONCLUSIONS ctDNA detection after initial treatment of patients with early-stage NSCLC using sensitive patient-specific assays has potential to identify patients who may benefit from further therapeutic intervention.

Abstract
Dark matter with Planck-scale mass (≃10^{19} GeV/c^{2}) arises in well-motivated theories and could be produced by several cosmological mechanisms. A search for multiscatter signals from supermassive dark matter was performed with a blind analysis of data collected over a 813 d live time with DEAP-3600, a 3.3 t single-phase liquid argon-based detector at SNOLAB. No candidate signals were observed, leading to the first direct detection constraints on Planck-scale mass dark matter. Leading limits constrain dark matter masses between 8.3×10^{6} and 1.2×10^{19} GeV/c^{2}, and ^{40}Ar-scattering cross sections between 1.0×10^{-23} and 2.4×10^{-18} cm^{2}. These results are interpreted as constraints on composite dark matter models with two different nucleon-to-nuclear cross section scalings.

Abstract
Background
The SYNTAX score II 2020 (SSII-2020), which was derived and externally validated from randomized trials, was designed to predict death following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with three-vessel disease and/or left main disease. We aimed to investigate its value in identifying the safest modality of revascularization in a non-randomized setting.
Methods
Five-year mortality was assessed in 7362 patients with three-vessel disease and/or left main disease enrolled in a Japanese PCI/CABG registry. New-generation drug eluting stents and imaging guidance became the default PCI strategy during enrolment of the last cohort. The discriminative ability of the SSII-2020 for 5-year mortality was assessed using Harrell's C statistic (C-index). Agreement between observed and predicted rates of all-cause mortality following either PCI or CABG and treatment benefit (absolute risk difference) for this outcome were assessed by calibration plots.
Results
The SSII-2020 had helpful discrimination (C-index = 0.72) and good calibration (intercept = −0.11, slope = 0.92) for 5-year mortality. The absolute risk difference in mortality between CABG and PCI (treatment benefit) was well calibrated when the whole population was grouped into quarters according to the predicted absolute risk difference of 5-year mortality. The observed differences in survival in favor of CABG were 4.2% (0.1 to 8.2%, log-rank p=0.05) and 8.5% (3.8 to 13.2%, log-rank p<0.01) in the respective third and fourth quarters. In contrast, the observed differences in survival were not significantly different in either the first (3.0% [−0.8 to 6.8%, log-rank p=0.12]) or the second quarter (1.3% [−2.4 to 5.1%, log-rank p=0.39]).
Conclusions
The SSII-2020 is well able to predict death at 5 years – and the mortality difference between PCI and CABG, and therefore has the potential to support decision making on revascularization in patients with three-vessel disease and/or left main coronary artery disease.

Pulse-shape discrimination against low-energy Ar-39 beta decays in liquid argon with 4.5 tonne-years of DEAP-3600 data. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:823. [PMID: 34720726 PMCID: PMC8550104 DOI: 10.1140/epjc/s10052-021-09514-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 07/30/2021] [Indexed: 06/13/2023]
Abstract
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from 39 Ar beta decays and is suppressed using pulse-shape discrimination (PSD). We use two types of PSD estimator: the prompt-fraction, which considers the fraction of the scintillation signal in a narrow and a wide time window around the event peak, and the log-likelihood-ratio, which compares the observed photon arrival times to a signal and a background model. We furthermore use two algorithms to determine the number of photons detected at a given time: (1) simply dividing the charge of each PMT pulse by the mean single-photoelectron charge, and (2) a likelihood analysis that considers the probability to detect a certain number of photons at a given time, based on a model for the scintillation pulse shape and for afterpulsing in the light detectors. The prompt-fraction performs approximately as well as the log-likelihood-ratio PSD algorithm if the photon detection times are not biased by detector effects. We explain this result using a model for the information carried by scintillation photons as a function of the time when they are detected.

Abstract
INTRODUCTION To evaluate the trends of C-reactive protein (CRP) and Erythrocyte sedimentation rate (ESR) in the first three weeks after uncomplicated total hip (THR) and total knee (TKR) arthroplasty/replacement in the Indian population and to compare it with available literature. MATERIALS AND METHODS A total of 90 patients were enrolled for this prospective study, of which 30 were unilateral THR, 30 were unilateral TKR (U/L TKR) and 30 were simultaneous bilateral TKR (B/L TKR). Serum CRP and ESR were measured on the day before surgery and post-operatively on day 1st, 2nd, 3rd, 7th, 12th, and at the end of 3rd week. RESULTS CRP showed a peak at day 2nd with normalisation to pre-operative value by the end of 3rd week. While ESR showed a peak on day 3rd and continued to remain elevated even at end of 3rd week post-operatively. Both mean CRP and ESR values were higher in THR patients followed by in B/L TKR and then in U/L TKR patients. CONCLUSION CRP persists to be the best acute phase reactant in the early post-operative phase with a relatively typical pattern as compared to ESR. CRP values peak at post-operative day 2nd and then show a gradual decline. However, its normalisation to pre-operative baseline values may vary among different groups of population.

Abstract
Abstract
Background
High maternal mortality in the state like Rajasthan, which is at second rank in terms of high Maternal Mortality Ratio (MMR) in India, require concentrated efforts in this direction The objectives of this study were to assess the magnitude and trend of maternal death and underlying factors contributing to maternal deaths in Rajasthan and to identify barriers and challenges in reporting maternal deaths in Rajasthan.
Methods
Data related to maternal deaths, cause of deaths and live births were retrieved from official Government sources and MMR was calculated. To find out the underlying factors contributing to maternal deaths, Verbal Autopsies were conducted through household surveys. In-depth interviews of health care staff were conducted to carry out the 'SWOT' analysis in order to identify the barriers in reporting maternal deaths. Data was analysed using SPSS version 23.
Results
A total of 7185 maternal deaths were reported from Rajasthan in last five years. The mean age of mothers was 25.18±4.98 years. Haemorrhage were reported as most common cause of maternal death (17%) followed by Severe hypertension or fits (8%) and obstructed labour (2%). The median duration of hospital stay was 23 hours (IQR=7.5-70). Maximum deaths were reported during post-partum period (61%), while around one fourth of the deaths happened during delivery.
Conclusions
The discrepancies were observed in the reporting of number and causes of maternal deaths. The trend and forecasted figures were quite different from the published National and State level reports in this regard.
Key messages
need to streamline and strengthen the Maternal Deaths Surveillance and Response to track the number of deaths and get the exact information about the underlying factors contributing to them. Effective strategies can be developed to reduce the Maternal Deaths in the State.

Abstract
BACKGROUND Abnormalities in the semantic and syntactic organization of speech have been reported in individuals at clinical high-risk (CHR) for psychosis. The current study seeks to examine whether such abnormalities are associated with changes in brain structure and functional connectivity in CHR individuals. METHODS Automated natural language processing analysis was applied to speech samples obtained from 46 CHR and 22 healthy individuals. Brain structural and resting-state functional imaging data were also acquired from all participants. Sparse canonical correlation analysis (sCCA) was used to ascertain patterns of covariation between linguistic features, clinical symptoms, and measures of brain morphometry and functional connectivity related to the language network. RESULTS In CHR individuals, we found a significant mode of covariation between linguistic and clinical features (r = 0.73; p = 0.003), with negative symptoms and bizarre thinking covarying mostly with measures of syntactic complexity. In the entire sample, separate sCCAs identified a single mode of covariation linking linguistic features with brain morphometry (r = 0.65; p = 0.05) and resting-state network connectivity (r = 0.63; p = 0.01). In both models, semantic and syntactic features covaried with brain structural and functional connectivity measures of the language network. However, the contribution of diagnosis to both models was negligible. CONCLUSIONS Syntactic complexity appeared sensitive to prodromal symptoms in CHR individuals while the patterns of brain-language covariation seemed preserved. Further studies in larger samples are required to establish the reproducibility of these findings.

Abstract
Background:Myths and misconceptions about illness and conventional disease modifying anti-rheumatic drugs directly influence adherence to the prescribed treatment. It is estimated that 30–50% of patients do not adhere to their prescribed treatment due to various reasons where the beliefs of the patients play a crucial role. At our centre we the specialist rheumatology nurse counsel the patients at every visit and try to remove their myths and negative beliefs about the disease as well as the medications.Objectives:•To explore the common myths and misconceptions of regarding their disease and regarding the csDMARDs.•To assess the efficacy of counseling in allaying their unfounded fear.Methods:A total of 450 patients with SIRDs at least 3 times attended the rheumatology out-patient clinic on csDMARDs were enrolled to complete a questionnaire that, besides demographic information, socio-economic status, and co- morbidities, had the following questions:1.Self reported adherence to medication2.Misbelieves regarding food items3.What kind of health-provider was consulted at the onset of the symptoms4.Their belief/knowledge regarding:A. The need for physiotherapy.B. Life style modification requirementC. About osteoarthritisD. Medication requirement during remissionE. Pregnancy and DMARDsF. The need of vaccinationG. Health hazards of smoking and alcohol useH. Harms of discontinuing treatment when they felt wellResults:A total of 450 patients included spondyloarthropathy 150(34%), rheumatoid arthritis 200(45.7%), psoriatic arthritis 45(10%), and others 25(5.5%).The following observations was made:1.Self-reported adherence to medication was in 250 (55%) patients; 200(45%) patient were non-adherent to treatment2.382/450 (85%) patients had misbelieves regarding different food items.3.225/450(50)% of the patients were not doing regular physiotherapy they were totally dependent on medications for symptoms relief.4.387/450 (86%) patients confused the symptoms of osteoarthritis with that of RA.5.315/450 (70 %) patients did not feel the requirement of continuing drugs during remission.6.135/450 (30%) patients believed that while on DMARDs they cannot contemplate pregnancy.7.351/450(78%) patients accept the need for vaccination when staring DMARDs8.360/450 (80%) patients aware about side effect of smoking in disease but only 40 % were able to quit.9.273/450 (60%) patients felt that more expensive medicines e.g.bDMARDs have more effects.10.360/450 (80%) patients believed that DMARDs were ‘steroids’ and they increased weight. On analysis one patient have more than two myths simultaneously.Conclusion:Increased awareness of the patient’s beliefs about medicines is needed among health care providers. We should encourage patients to express their views about medicines as well as disease in order to optimize and personalize the information process. This can stimulate concordance and adherence to medication and follow up.These myths are deeply rooted in our society, single sitting counseling is not enough, and reinforcement is needed.References:[1]Tom Greenhalgh.

Abstract
Background:Patients with systemic immunoinflammatory rheumatic diseases (SIRDs) are often treated with bDMARDs when the response to conventional disease-modifying antirheumatic drugs (csDMARDs) is inadequate.There are, however, concerns about non-adherence to bDMARDs among patient. The non-adherence to bDMARDs may be caused by the various factors.Objectives:1.The main objective of present study was to find out the cause of discontinuation of bDMARDs2.To find out the adherence and non-adherence rate for bDMARDs.3.To identify the factors that are modifiable.Methods:800patients with SIRDs prescribed bDMARDs were interviewed to find out the demographic information, their socioeconomic status,and the disease duration.Additional information gathered included the comorbidities, the time for starting bDMARDs, the route of administration of bDMARDs, beliefs and perceptions about treatment efficacy and side effects if any.This was followed by looking at the adherence of bDMARDs; if they had discontinued then efforts was made to find out the reasons for the same.Based on these findings the patients were classified into adherent and non-adherent categories. The data were analyzed further for1.Factors that associated with persistence of bDMARDs.2.Factors that were associated with discontinuation of bDMARDs.Results:A total of 800 patients were interviewed that included patients with ankylosing spondylitis 430(52.4%), rheumatoid arthritis 300(37.7%), psoriatic arthritis 45(5.2%), and others 25 (0.7%).On analysis 610(76%) patient were compliant but 190(24%) patient had discontinued the bDMARDs on their own. On comparison of both groupsFactors that were significantly related to self-discontinuation were:•Negative beliefs about biologics (37%)•Cost (33%)•Reading side-effect profile on Google search (25%)•Other co-morbidities (6%)Factors that were significantly related to persistence of biologic treatment were:•Good counseling by rheumatologist and rheumatology nurse (60%)•Faith in the treating rheumatologist (25%)•Fear of deformities and pain(15%)On analysis it was found that a good counseling and clarifying the doubts of the patients regarding bDMARDs before starting the treatment encourages the patient to continue the biologic treatment, especially it allays their doubts about the drug adverse effects.Conclusion:Despite negative beliefs and misconceptions about bDMARDs, patient non-adherence at our center is not alarming.A positive reinforcement counseling appears to be the most significant factor to overcome the negative belief of patients.The affordability of the biologic treatment however remains a limiting factor in our centre as in other parts of India.References:[1]Tamas Koncz,MD,Marta,Pentek,Valentin,Brodszky,Katalin Ersek,MSc,Ewaorlewska&Laszlo Gulasi Volume10,2010 –Issue9 Adherence to biologic DMARD therapies in rheumatoid arthritisAcknowledgments:noDisclosure of Interests:None declared

Abstract
Background:Systemic sclerosis (SSc) is an autoimmune the disease of the connective tissue that is clinically characterized by the involvement of skin (fibrosis, contractures of the finger joints), microvascular abnormalities (Raynaud’s phenomenon and complications), gastrointestinal involvement (gastroesophageal reflux disease - GERD, the lower GI tract involvement), musculoskeletal involvement (polyarthralgia, muscle disease), and involvement of internal organs (especially lungs, heart, and kidneys). Lifestyle modification techniques could have significant impact on various aspects of the disease including early disease control, increased drug adherence, positive attitude towards life, decreased financial burden of treatment, maintaining mobility and joints range of motion, minimizing or delaying joint contractures and decreased dependency with regular physical therapy. Counselling explaining the benefits of lifestyle modification related to these aspects of daily living may make a major difference in the quality of life of the patients with SSc.Objectives:To assess the benefits of lifestyle modification technique in improving the quality of life in patients with SSc.Methods:Patients with SSc attending the Rheumatology clinic of this institution, willing to participate in the survey, were enrolled in this study. All the information including the follow-up details were recorded in a pre-designed form. Their demographic information (age, gender) and disease characteristics (diagnosis, duration, treatment) were recorded, All the patients were explained the lifestyle modifications and their benefits, reinforced at each follow-up visit using posters (visual), written lifestyle modification techniques (using printed material) to raise their awareness of how to improve several of the above manifestations of SSc.Results:One hundred fifty (n=150) consecutive SSc patients were included in the study. It was observed that with repeated counselling 125 (83.3 %) patients adopted the lifestyle modification technique according to the advice imparted and felt a positive benefit in their daily life. However, 25 (16.6%) could not or did not follow the imparted lifestyle change advice on a regular basis. Those who were able to modify the life-style as counselled showed the following results:80 % were able to avoid exposure to cold by adopting the following measures: Wearing gloves and extra woolen socks, using mittens most of the time, wearing woollen undergarments to keep the central regions of the body region warm. These patients noted 55% decrease in the episodes of Raynaud’s phenomenon.Early evening meals and raising the head-end of the bed: 60% decrease in gastrointestinal symptoms.Regular physiotherapy: 65 % decrease dependency on others; 55% could maintain flexibility with physical exercises.Regular application and rubbing of the skin with lanoline-containing skin moisturizers 60 % improve your skin’s health80% were able to avoid active and passive tobacco use.Conclusion:The lifestyle modification techniques are important to control disease and its complications. Thus, after intense and regular counselling by the specialist rheumatology nurses on the lifestyle modification technique (83.3%) adapted the advised lifestyle modifications. The study showed the important role specialist rheumatology nurses can play in educating patients and helping them improving their quality of life.References:[1] Hudson M, Thombs BD, Steele R. at ell.

Abstract
Background: Inappropriate endotracheal tube placement depth may be associated with complications.
Objective: To determine whether the accurate alignment of the indicator ring on the endotracheal tube at the level of the vocal cords, results in its appropriate placement.
Design: Prospective observational study.
Patients: 98 adult patients scheduled for general anesthesia with orotracheal intubation.
Interventions: The indicator band mark on the endotracheal tube was accurately placed at the vocal cords level under video-laryngoscope view. The tube length at the right upper incisor and the distance between its tip and the carina was measured using fibreoptic bronchoscope. Data to validate methods to predict insertion depth was collected and evaluated.
Main Outcome: To determine the distance between the tip of the endotracheal tube and the carina.
Results: The endotracheal tube tip depth was inap- propriate in 46.94% cases and was <3 cm above the carina in 41.64% cases. This difference in this distance was similar (p = 0.246) in the two genders. A correlation was noted between topographic length and insertion depth in females only (r2 = 0.201 and p = 0.001). The mean tracheal length was 12.66 + 1.35 cm in males and 12.04 + 1.26 cm in females.
Conclusion: We found a high incidence of endo- tracheal tube tip malposition despite the accurate placement of the indicator band at the vocal cords level. We suggest that international endotracheal tube design standards be defined and endotracheal tube manufacturers modify the standard intratracheal length.

Abstract
We present a table-top beamline providing a soft X-ray supercontinuum extending up to 370 eV from high-order harmonic generation with sub-13 fs 1300 nm driving pulses and simultaneous production of sub-5 fs pulses centered at 800 nm. Optimization of high harmonic generation in a long and dense gas medium yields a photon flux of ~ 1.4 × 106 photons/s/1% bandwidth at 300 eV. The temporal resolution of X-ray transient absorption experiments with this beamline is measured to be 11 fs for 800 nm excitation. This dual-wavelength approach, combined with high flux and high spectral and temporal resolution soft X-ray absorption spectroscopy, is a new route to the study of ultrafast electronic dynamics in carbon-containing molecules and materials at the carbon K-edge.

Abstract
Azathioprine and 6-mercaptopurine have been widely used for maintenance of remission in patients with inflammatory bowel disease. The use of thiopurines is associated with multiple adverse effects including dose dependent cytopenias or idiosyncratic reaction. We report about a case of azathioprine related pancreatitis associated with polyarthralgia and panniculitis. Pancreatitis, polyarthritis and panniculitis (PPP) syndrome is an uncommon phenomenon which may accompany a number of pancreatic diseases including acute or chronic pancreatitis or pancreatic malignancy. To the best of our knowledge, this is the first report of Azathioprine related PPP syndrome.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a major cause of hospitalizations in young children. We estimated the burden of community-onset RSV-associated hospitalizations among US children aged <2 years by extrapolating rates of RSV-confirmed hospitalizations in 4 surveillance states and using probabilistic multipliers to adjust for ascertainment biases. METHODS From October 2014 through April 2015, clinician-ordered RSV tests identified laboratory-confirmed RSV hospitalizations among children aged <2 years at 4 influenza hospitalization surveillance network sites. Surveillance populations were used to estimate age-specific rates of RSV-associated hospitalization, after adjusting for detection probabilities. We extrapolated these rates using US census data. RESULTS We identified 1554 RSV-associated hospitalizations in children aged <2 years. Of these, 27% were admitted to an intensive care unit, 6% needed mechanical ventilation, and 5 died. Most cases (1047/1554; 67%) had no underlying condition. Adjusted age-specific RSV hospitalization rates per 100 000 population were 1970 (95% confidence interval [CI],1787 to 2177), 897 (95% CI, 761 to 1073), 531 (95% CI, 459 to 624), and 358 (95% CI, 317 to 405) for ages 0-2, 3-5, 6-11, and 12-23 months, respectively. Extrapolating to the US population, an estimated 49 509-59 867 community-onset RSV-associated hospitalizations among children aged <2 years occurred during the 2014-2015 season. CONCLUSIONS Our findings highlight the importance of RSV as a cause of hospitalization, especially among children aged <2 months. Our approach to estimating RSV-related hospitalizations could be used to provide a US baseline for assessing the impact of future interventions.

Abstract
Abstract
Objectives
To investigate the impact of ticagrelor monotherapy following one-month dual antiplatelet therapy (DAPT) on clinical outcomes after percutaneous coronary intervention (PCI) in patients with established cardiovascular disease (CVD) who were enrolled in the Global Leaders Trial.
Background
The impact of prolonged monotherapy with P2Y12 inhibitors after PCI in patients with CVD is undetermined.
Methods
GLOBAL LEADERS was a randomized, superiority, all-comers trial comparing one-month DAPT with ticagrelor and aspirin followed by 23-month ticagrelor monotherapy (experimental treatment) with standard 12-month DAPT followed by 12-month aspirin monotherapy (reference treatment) in patients treated with a biolimus A9-eluting stent. The cohort was stratified according to those with- and without established CVD, defined as a history of ≥1 prior myocardial infarction (MI), PCI, coronary artery bypass operation, stroke or peripheral vascular disease. The degree of CVD was defined according to the number of vascular territories effected (1, 2, ≥3). The primary endpoint was a composite of all-cause death or new Q-wave MI at 2-years. Secondary endpoints were the patient orientated composite endpoint (POCE) of death, stroke, MI and any revascularization; definite stent thrombosis and net adverse cardiovascular events a composite of POCE and BARC 3 or 5 bleeding.
Results
Amongst the 15,761 patients included in this cohort were 6693 patients (42.5%) with- and 9068 patients without established CVD. Patients with CVD were older, and had significantly higher rates of diabetes, hypertension, and hypercholesterolaemia (P<0.01). The incidence of the primary endpoint was significantly higher in patients with established CVD (5.1% vs. 3.3%, P<0.001) as were all secondary endpoints and their individual components. There was a trend for a reduction in the primary endpoint in patients with established CVD receiving the experimental treatment (4.6% vs. 5.6%, HR0.82 [0.66–1.02], p=0.07), which was not seen in those without prior CVD (3.2% vs. 3.3%, HR 0.95 [0.76–1.19, p=0.66; p(interaction)=0.37).
Compared with patients without CVD the incidence of the primary and second endpoints and all their individual components, other than BARC 3/5 bleeding, rose significantly with an increasing degree of CVD.
In an unadjusted model, compared with patients without CVD, the hazard ratio for the primary endpoint rose from 1.5 (1.21–1.81) to 3.0 (2.32–4.00) in patients with one and three territories of CVD, respectively. Similar rises were seen in models adjusted by age (1.3 [1.01–1.60] to 2.56 [1.94–3.38]) and age, left ventricular ejection fraction, clinical presentation and anti-platelet strategy (1.4 [1.10–1.68] to 2.26 [1.69–3.02]).
Conclusions
PCI outcomes are poorer in patients with increasing degrees of CVD compared to those without. Prolonged monotherapy with ticagrelor does not mitigate this risk suggesting a greater need to focus on modifiable risk factors

Abstract
This article describes the clinical protocol of using potassium iodide (KI) to reverse staining caused by silver diamine fluoride (SDF). SDF contains silver, fluoride, and ammonia. It has been used to arrest dental caries mainly in pediatric applications. The major drawback of SDF application is the dark staining of both teeth and restorative materials. Hence, its use on adult dentition is limited. Improving the esthetic outcome by stain reduction would greatly enhance the opportunity for SDF's universal use. This case demonstrates how KI can effectively reverse the staining.

Abstract
INTRODUCTION Minimal invasive surgery has proven its advantages over open surgeries in the perioperative period. Food and Drug Administration approved da Vinci robot in 2000. The latest version, da Vinci Xi system has a mobile tower-based robot with several modifications to improve the functionality, versatility, and operative ease. None of the centers have reported exclusively on hepatobiliary oncology using the da Vinci Xi system. We report our initial experience. AIMS AND OBJECTIVES To study the feasibility, advantages, and discuss the operative technique of da Vinci Xi system in hepatobiliary oncology. MATERIALS AND METHODS Data were analyzed retrospectively from a prospectively maintained database from June 2015 to October 2016. Twenty-five patients with suspected or proven hepatobiliary malignancies were operated. Total robotic technique using da Vinci Xi system was used. Demographic details and perioperative outcomes were noted. RESULTS Of the 25 surgeries, 14 patients had a suspected gallbladder malignancy, 11 patients had primary or metastatic liver tumor. Median age was 53 years. The average duration of surgery was 225 min with a median blood loss 150 ml. The median postoperative stay was 4 days. The median nodal yield for radical cholecystectomy was seven. Five patients required conversion. Two of these developed postoperative morbidity. CONCLUSION Robotic surgery for hepatobiliary oncology is feasible and can be performed safely in experienced hands. Increasing experience in this field may equal or even prove advantageous over conventional or laparoscopic approach in future. A cautious approach with judicious patient selection is the key to establishing robotic surgery as a standard surgical approach.

Abstract
BACKGROUND Surgical treatment for lung cancer has evolved from pneumonectomy to lobectomy/sleeve resection around the world. Although condemned for poor outcomes, pneumonectomy may still be required in a select group of patients in developing countries. With the better patient selection, optimization of medical comorbidities, better perioperative care; pneumonectomy may show better results. Thus, there is a need to reconsider the role of pneumonectomy in patients with locally advanced lung cancer in the current scenario. PATIENTS AND METHODS The aim of this study was to analyze the demographic and clinicopathologic profile of lung cancer patients and the role of pneumonectomy at a tertiary cancer center in India. The records of patients, who underwent surgery for lung cancer at our institute from January 2011 to April 2014, were analyzed retrospectively, and various parameters in pneumonectomy were compared to lobectomy patients. RESULTS Out of 48 patients undergoing major lung resections, nearly 80% patients were symptomatic at presentation and were mostly in advanced stages, thus requiring neoadjuvant chemotherapy in 45.8% cases and pneumonectomy in 41.6% patients. There was no difference in morbidity and mortality in pneumonectomy (25%, 5%) versus lobectomy (21.2%, 3.5%). Disease-free survival at 1, 2, and 3 years after pneumonectomy (71.8%, 51.4%, and 42.8%) was comparable to lobectomy (73.3%, 66.1%, and 55.6%). After neoadjuvant therapy, survival was not affected by the type of surgery. CONCLUSIONS In the Indian scenario, as the majority of lung cancer patients present at an advanced stage, pneumonectomy still plays a major role, and the acceptable postoperative outcome can be achieved with aggressive perioperative management.

Power outages and refrigerated medicines: The need for better guidelines, awareness and planning. J Clin Pharm Ther 2018; 43:737-739.

Abstract
WHAT IS KNOWN AND OBJECTIVE Vaccines and other pharmaceuticals are essential medical supplies that require continuous storage at specific temperatures to maintain viability. Power outages can lead to a break in the cold chain, resulting in the degradation of essential medicines. COMMENT After a power outage, the stability of vaccines and other medicines can be difficult to ascertain. Many public health guidelines therefore recommend discarding potentially compromised pharmaceuticals unless the cold chain can be guaranteed-a costly endeavour. There are government guidelines aimed at minimizing exposure to high temperatures in the event of a power outage; however, the usefulness of these guidelines is uncertain. WHAT IS NEW AND CONCLUSION The actual cost of vaccine and pharmaceutical loss due to a break in the cold chain is poorly studied and requires further research. Additional recommendations regarding the stability of specific medicines would also be a valuable resource.

Abstract
Polyproteins, individual protein units joined covalently in tandem, have evolved as a promising tool for measuring the dynamic folding of biomacromolecules in single-molecule force spectroscopy. However, the synthetic routes to prepare polyproteins have been a bottleneck, and urge development of in vitro methods to knit individual protein units covalently into polyprotein. Employing two enzymes of orthogonal functionalities periodically in sequence, we synthesized monodispersed polyproteins on a solid surface. We used Sortase A (SrtA), the enzyme known for sequence specific transpeptidation, to staple protein units covalently through peptide bonds. Exploiting the sequence-specific peptide cleaving ability of TEV protease, we controlled the progress of the reaction to one attachment at a time. Finally, with unique design of the unit proteins we control the orientation of proteins in polyprotein. This simple conjugation has the potential to staple proteins with different functionalities and from different expression systems, in any number in the polyprotein and, above all, via irreversible peptide bonds. Multiple chimeric constructs can also be synthesized with interchangeable protein units.

Abstract
Purpose To evaluate the short-term efficacy and safety of intravitreal bevacizumab in myopic choroidal neovascularization (mCNV). Methods In this noncomparative, consecutive, interventional case series, 12 eyes of 11 patients with mCNV without any previous treatment were included. Patients received intravitreal bevacizumab (1.25 mg/0.05 mL) at baseline and at 4 weeks interval, if optical coherence tomography (OCT) showed presence of intraretinal edema, subretinal fluid, and/or pigment epithelial detachment. Patients were followed up for a minimum of 6 months and changes in best-corrected visual acuity, central macular thickness (CMT) on OCT, angiographic characteristics, and complications were assessed. Results The mean refractive error was −11.25 diopters. At 6 months the mean best-corrected visual acuity (BCVA) improved from 20/235 (median 20/235) to 20/71 (median 20/80) (p=0.01). The mean CMT was reduced from 403 μm (median 365 μm) to 229 μm (median 239 μm) (p=0.002). At final visit 9 eyes (75%) had an improvement of BCVA of three lines or more, and only 1 eye (8%) lost two lines. No significant ocular or untoward systemic side effects were observed. Conclusions In this small series short-term results suggest that intravitreal bevacizumab (1.25 mg/0.05 mL) is safe, effective, and well tolerated in patients with choroidal neovascularization due to high myopia. Further evaluation in large series with longer follow-up is needed to confirm long-term efficacy and safety in such cases.
