Abstract
PURPOSE/OBJECTIVE(S) Health-related Quality of life (HRQOL) may be decisive when different treatments yield comparable survival outcomes. We compared QOL in patients undergoing radical cystectomy with ileal conduit (RCIC) or bladder preservation (BP) with (chemo)radiotherapy for bladder cancer. MATERIALS/METHODS Patients with histological diagnosis of bladder cancer, stage T1-T4, N0-N1, M0 with a minimum follow-up of 6 months from the last treatment intervention (RCIC or BP) and alive without disease at the time of QOL assessment were eligible for inclusion. After ethics committee approval, two HRQOL instruments were translated, validated and administered: Bladder cancer index (BCI) for bladder cancer-specific HRQOL, which includes 36 items under three domains - bladder, bowel and sexual function and the EORTC QLQ C30 which includes 30 items under three domains - functional, symptom and global health. The mean QOL scores across various domains and specific questions were compared between the two treatment groups using the independent t-test. RESULTS Of the 104 patients enrolled, 56 had RCIC, and 48 received BP, and included 95 (91.3%) males. The median time from treatment completion to QOL assessment was 22 months (IQR 10-56). The median age for the entire cohort was 62 years (IQR 55-68), 65.5 years (IQR 55-71) in BP and 59.5 years (IQR 55-66) in RCIC. Overall, mean BCI urinary scores and bowel scores were high in both groups, with no significant difference in function or bother subdomains between the two groups (Table 1). Overall, BCI sexual scores were low in both the groups but significantly better after BP (BPmean 56.9, RCICmean 41.5, p = 0.01). Mean scores for sexual function BPmean 38.4 and RCIC mean 25 p (0.07) and sexual bother BPmean 81 RCICmean 62 (p 0.02) subdomains. There was no significant difference in EORTC QOL outcomes in functional (BPmean 91.4, RCICmean 88.7 p 0.23), symptom (BPmean 89.8, RCICmean 89, p = 0.68) and global health scale (BPmean 76.8, RCICmean 78.5, p = 0.69) in both groups. On question-wise assessment, the ability to perform an exercise (BPmean 94.2, RCICmean 85, p = 0.06) and urinary leakage at night time (BPmean 91.7, RCICmean 77.6, p = 0.01) were better in the BP group, while scores for blood in the urine (BPmean 89.1, RCICmean 97, p = 0.05) were better in the RCIC group compared to BP. CONCLUSION Overall, QOL was good in both groups in the urinary and bowel domains while it was low in the sexual domain. However, bladder preservation performed significantly better in the sexual domain than RCIC.

Abstract
AIMS To assess the efficacy and safety of adjuvant radiotherapy in patients with high-risk muscle-invasive bladder cancer (MIBC) following radical cystectomy (RC) and chemotherapy. MATERIALS AND METHODS The BART (Bladder Adjuvant RadioTherapy) trial is an ongoing multicentric, randomised, phase III trial comparing the efficacy and safety of adjuvant radiotherapy versus observation in patients with high-risk MIBC. The key eligibility criteria include ≥pT3, node-positive (pN+), positive margins and/or nodal yield <10, or, neoadjuvant chemotherapy for cT3/T4/N+ disease. In total, 153 patients will be accrued and randomised, in a 1:1 ratio, to either observation (standard arm) or adjuvant radiotherapy (test arm) following surgery and chemotherapy. Stratification parameters include nodal status (N+ versus N0) and chemotherapy (neoadjuvant chemotherapy versus adjuvant chemotherapy versus no chemotherapy). For patients in the test arm, adjuvant radiotherapy to cystectomy bed and pelvic nodes is planned with intensity-modulated radiotherapy to a dose of 50.4 Gy in 28 fractions using daily image guidance. All patients will follow-up with 3-monthly clinical review and urine cytology for 2 years and subsequently 6 monthly until 5 years, with contrast-enhanced computed tomography abdomen pelvis 6 monthly for 2 years and annually until 5 years. Physician-scored toxicity using Common Terminology Criteria for Adverse Events version 5.0 and patient-reported quality of life using the Functional Assessment of Cancer Therapy - Colorectal questionnaire is recorded pre-treatment and at follow-up. ENDPOINTS AND STATISTICS The primary endpoint is 2-year locoregional recurrence-free survival. The sample size calculation was based on the estimated improvement in 2-year locoregional recurrence-free survival from 70% in the standard arm to 85% in the test arm (hazard ratio 0.45) using 80% statistical power and a two-sided alpha error of 0.05. Secondary endpoints include disease-free survival, overall survival, acute and late toxicity, patterns of failure and quality of life. CONCLUSION The BART trial aims to evaluate whether contemporary radiotherapy after standard-of-care surgery and chemotherapy reduces pelvic recurrences safely and also potentially affects survival in high-risk MIBC.

Abstract
BACKGROUND Long-distance runs with equipment are practised in military training establishments to develop physical stamina and prepare for battles. A study was planned to quantify and compare the physiological and mental workloads of the early and late finishers of a military endurance run through the jungle terrain of north-eastern India in hot and humid conditions. METHODS Twenty-five soldiers of the Indian Army completed a 15 km run through a rural and jungle track with 6.5 kg of equipment. Twelve participants who finished the race before 130 min were categorised as 'early finishers', and 13 were categorised as 'late finishers' who finished the race after 130 min. Physiological parameters, viz., heart rate (HR), breathing rate (BR), estimated core temperature (ECT), peak acceleration (PAC), and physiological intensity (PHYI) and mechanical intensity (MECHI) were recorded using BioHarness V.3 (Zephyr Technologies, USA) and NASA Task Load Index scores were obtained to assess mental workload. Mann-Whitney U test was applied to assess the level of significance at a p value of <0.05. RESULTS HR, ECT and PAC were significantly higher (167.9 and 156.0 beats/min, 39.0℃ and 38.4℃, and 1.1 and 1.0 g, respectively) for the first group compared with the second group. The second group expressed higher BR and subjective responses ('total scores' were 76.5 and 82.5, respectively) than the first. The PHYI was significantly higher (from 7.2 to 6.3) for the first group, whereas the MECHI was similar in both groups. CONCLUSION The successful completion by the first group can be attributed to their motivation to continue heavy work in an adverse environment, and their ability to negotiate with natural obstacles was reflected through controlled subjective responses. Adoption of a possible safe and stable approach to the same task might have led the second group to take a longer duration, exert higher mental effort and demand lower physiological cost.

Abstract
AIMS Due to the lack of high-quality evidence and consensus on adjuvant treatment for locoregionally advanced penile cancer, we reviewed the outcomes of pN3 patients to determine the suitable adjuvant treatment options. PATIENTS AND METHODS All consecutive pN3 penile cancer patients treated at our institution between January 2010 and December 2018 were reviewed to assess the impact of demographical, pathological and treatment factors on disease-free survival (DFS) and overall survival. The DFS and overall survival were estimated using the Kaplan-Meier method and association was tested using the Cox regression model (two-sided test with P < 0.05 considered significant). RESULTS Of 128 patients, 31 (24%) had pelvic nodal involvement. Twenty-six patients (20.3%) received no adjuvant treatment, 40 (31.3%) received single modality adjuvant treatment and 62 (48.4%) received multimodality adjuvant treatment (a combination of chemotherapy and radiotherapy). At a median follow-up of 22 months, the DFS and overall survival were 55.4 and 62%, respectively. The best DFS and overall survival was noted with chemotherapy followed by concurrent chemoradiation (C-CTRT; 93% each). On multivariate analysis, both DFS and overall survival were worse with pelvic node involvement (2.2 [1.3-4], P = 0.027 and 2.2 [1.3-4], P = 0.027, respectively) and better with any adjuvant treatment (single modality: 3 [1.5-5.5], P < 0.001; multimodality: 3.1 [1.6-6], P < 0.001). C-CTRT was associated with improved DFS over chemotherapy alone (0.17 [0.4-0.78], P = 0.02) but not over radiotherapy alone (0.35 [0.07-1.6], P = 0.19). In patients with no pelvic nodes involved, chemotherapy and radiotherapy as single modalities were associated with similar DFS and overall survival. In patients with pelvic nodes, multimodality treatment was associated with better DFS than single modality treatment (0.3 [0.1-1], P = 0.05). CONCLUSION pN3 penile cancer is a diverse prognostic group with poorer outcomes associated with pelvic nodes. Single modality adjuvant treatment may be adequate in inguinal nodes with extranodal extension, but multimodality treatment should be given in patients with pelvic nodal involvement.

Abstract
AIMS There is a lack of consensus regarding the management of post-chemotherapy residual mass in classical seminoma. The use of fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) may aid the detection of residual masses harbouring viable disease and help to tailor therapy. The aim of this study was to evaluate if PET-CT could identify patients who will benefit from locoregional radiotherapy. MATERIALS AND METHODS This ethics-approved study included patients with advanced classical seminoma primarily treated with standard platinum-based first-line chemotherapy. Patients were either observed or given adjuvant radiotherapy based on the clinician's preference and followed up. For this study, patients were stratified into two groups based on FDG PET-CT residual nodal maximum standardised uptake value (SUVmax): low risk (SUVmax <3) and high risk (SUVmax ≥3). Further subgroup analysis was carried out for patients with residual nodal size ≥3 cm and SUVmax ≥3, and this was considered as the very high risk group. The diagnostic accuracy of FDG PET-CT was assessed and survival was compared between the different groups. RESULTS Sixty-nine patients were included in the study: 48 patients were observed and 21 received radiotherapy. The low and high risk groups contained 50.7% and 49.3% of the patients, respectively. The very high risk subgroup had 24 patients. At a median follow-up of 44 months, locoregional failures in the radiotherapy and observation cohorts were 0% and 30% (P = 0.059) in the very high risk subgroup and 5.8% and 29.4% (P = 0.078) in the high risk group. The positive predictive value for the very high risk and high risk groups was 30% and 17.1%, respectively. The benefit of locoregional control failed to translate into overall survival benefit. CONCLUSION A tailored, FDG PET-based risk-adapted treatment approach can refine the management of post-chemotherapy residual masses in seminoma. In this study, with the largest cohort of advanced seminoma patients treated with radiotherapy reported to date, radiotherapy seems to benefit patients with post-chemotherapy residual mass SUVmax ≥3.

Abstract
Abstract
Background
Outcomes for different subtypes of aortic stenosis defined by transvalvular flow and gradient after transcatheter aortic valve implantation (TAVI) are still subjects of debate.
Purpose
The aim of the study was to evaluate the prognostic impact of the initial transvalvular flow rate and aortic mean gradient on survival and to assess the changes of left ventricular function after TAVI.
Patients and Methods
From 2008. to 2017.06.30. TAVI was performed in 300 cases in our Institute (127 men, 173 women, mean age 80,0 ± 5,8 years) with severe (aortic valve area <1,0 cm²) symptomatic aortic stenosis (AS) and contraindication or high risk for surgery. Median time for follow-up was 28 (0-115) months, Echocardiography was performed before and 12 months after TAVI. Patients were divided into four groups according to flow (F) , aortic mean gradient (Gr) and ejection fraction (EF):
HG
Gr ≥ 40 mmHg (n = 237)
LF-LG : F ≤ 35 ml/m2, Gr < 40 mmHg and EF < 50% (n = 41)
PLF-LG: F ≤ 35 ml/m2, Gr < 40 mmHg and EF ≥50% (n = 9)
NF-LG: F > 35 ml/m2 and Gr < 40 mmHg (n = 13)
Our primary objective was the analysis of 30-day, 1-year and 3-year all-cause mortality of these groups, secondary goal was to observe the changes in EF after 12 months in the survivors.
Results
In the whole patient group 30-day all-cause mortality was 4,3%, 1-year 17,0% and 3-year 62,0%. The NFLG group had the most favourable outcomes (mortality: 30d 0, 1-year: 7,7%, 3-year: 46,2%). Mortality was low in the HG group in the 1st year (30-day: 3,8%, 1-y: 14,3%), but it increased to 62,8% at 3-year. Mortality rates were intermediate in the PLF-LG group (30-day 0, 1-year 22,2%, 3-year 55,6%) and were the highest in LF-LG (30-day 12,2%, p = 0,03 vs HG, 1-year 34,2% p = 0,005 vs. HG, 3-year 75,6%).
Among clinical and echocardiographic variables only moderate or severe paravalvular aortic regurgitation (p = 0,03) and severe renal dysfunction (GFR <30 ml/min, p = 0,02) were independent predictors of all-cause 1-year mortality.
In patients with severe (EF < 30%) , moderate (EF 30-40%) or mild ( EF 41-50%) systolic dysfunction the EF improved after TAVI (23,5 ± 3,5% vs. 30,3 ± 7,9% p < 0,001, 33,6 ±3,6% vs. 43,0 ± 10,5% p = 0,003, 45,5 ± 3,1% vs. 54,3 ± 8,7% p < 0,001) regardless of the initial flow and gradient subtype of AS.
Conclusions
Low flow-low gradient aortic stenosis is associated with worse short or long term prognosis after TAVI, therefore this subtype of AS needs detailed risk stratification before-, and careful management after TAVI. Improvement of initial left ventricular dysfuncion can be expected after TAVI.

Abstract
AIMS To report long-term outcomes with dose-escalated, image-guided adaptive radiotherapy (ART) for bladder preservation in muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS All MIBC patients receiving bladder-preserving ART at our institute from 2009 to 2018 were analysed. For ART, three anisotropic planning target volumes (PTV) were concentrically grown around the simulation bladder volume. A library of intensity-modulated radiotherapy plans was created for each patient. A total dose of 64 Gy in 32 fractions to the entire bladder and 55 Gy to pelvic nodes was planned, with 68 Gy to the tumour bed (2 Gy equivalent dose = 68.7 Gy, α/β = 10) as simultaneous integrated boost for solitary tumours. The most appropriate PTV encompassing the bladder ('plan-of-the-day') was chosen daily using on-board megavoltage imaging. Neoadjuvant and concurrent chemotherapy was prescribed for medically fit patients. RESULTS Of a total of 106 patients, most had T2 (68%) or T3 (19%) disease. Ninety-two patients (87%) completed 64 Gy to the whole bladder. Sixty-three patients (59%) received 68 Gy as tumour bed boost. Seventy-six per cent received concurrent weekly chemotherapy. At a median follow-up of 26 months, 3-year locoregional control, disease-free survival and overall survival were 74.3, 62.9 and 67.7%, respectively. Eighty-two per cent of patients retained disease-free bladder. Radiation Therapy Oncology Group grade III/IV acute genitourinary and gastrointestinal toxicities were 7.5% and 0%, respectively, and late genitourinary/gastrointestinal toxicities were 6.5% and 3.8%, respectively. Overall survival, disease-free survival, locoregional control and grade III/IV genitourinary/gastrointestinal toxicities did not differ significantly with dose escalation. CONCLUSION Plan-of-the-day ART is clinically safe and effective for bladder preservation and can be implemented in routine clinical practice. A high bladder preservation rate is achievable without compromising on survival or toxicities. Dose escalation does not seem to affect outcomes.

Abstract
BACKGROUND Operation of infantry combat vehicle (ICV) influences the cardiorespiratory responses as well as the risk of vibration exposure on the crew members which adversely affect their performance and health. AIM To assess the effect of stress factors, that is, ICV's compartmental temperature, relative humidity (RH) and vehicular vibration on the physiological parameters (heart rate (HR), respiratory frequency (RF), estimated core body temperature (ECT)) of the crew members during the ICV operation. METHODS A 1 hour run trial of the ICV operation was conducted with its crew members at their respective positions. Compartmental temperature and RH were monitored at an interval of every 15 min during the run trial. Physiological parameters were monitored continuously during the run trial. Whole body vibration (WBV) and hand-arm vibration (HAV) of the crew members were also measured during the run trial time. RESULTS The findings showed a strong positive correlation (p<0.05) between the increasing compartmental temperature and RH with its run trial time. Significant changes were observed in the physiological parameters (p<0.05) along with the increasing run trial time. Additionally, the physiological parameters showed a strong positive correlation with compartmental temperature and RH, respectively (p<0.05). Also, a significant increase (p<0.05) in the muscle strength was recorded after their exposure to ICV operation. The study also confirmed high level of WBV exposure of the crew members during the ICV operation. CONCLUSION Increase in HR, RF and ECT along with increase in temperature and RH is a predictive indicator of physiological stress. Moreover, high levels of vibration exposure of various operations may bring deleterious effect on soldiers' health as well as their performance. Proper ergonomic intervention can reduce exposure to vibration, physiological stress and increase comfort which may ultimately ensure an optimum performance of soldiers and successful completion of mission.

Abstract
Background: Saliva based diagnostic can play an important role in the translational research related to cancer diagnostics and treatment. It is easily available, noninvasive, low storage cost, has less contamination chances with simple collection procedure. Cancers related to tobacco use, including oral cancer account for about 30% of all cancers in males and females. Five years' survival rate remains the same even after decades of advancement of detection, prevention, and treatment of OSCC (oral squamous cell carcinoma) mainly due to late diagnosis of oral potentially malignant disorders (OPMDs). Aim: Combinatorial characterization of saliva, endorsing multidimensional spectroscopic signatures using suitably designed biochamber. Methods: Eighteen saliva samples (6 normal, 6 OSF [oral submucous fibrosis, a type of OPMD] and 6 confirmed OSCC) were collected from GNIDSR (Guru Nanak Institute of Dental Science and Research) Kolkata. Ethical approval was obtained for the study and all the participants were explained the objectives of the study and a written informed consent was obtained from them. Participant's demographic detail and clinical characteristics were also recorded. The participants were asked not to consume food 1 hour before sample collection and were suggested to rinse their mouth 30 minutes prior to saliva expectoration to minimize the contamination of food in saliva. Empty, sterile, graded tubes were used for this purpose. The subjects were asked not to clear nose or throat during the process of saliva expectoration to avoid forced phlegm from other part of the respiratory tract. The saliva samples were then immediately transferred to −20 degrees and later in −80 degrees for long storage. The electrical impedance (EI) of saliva was measured in custom made biochambers with copper electrodes. The EI was measured for the frequency sweep from 20 Hz to 2 MHz using an impedance analyzer. Apart from EI measurement, the corresponding samples were subjected to FTIR (Fourier-transform IR spectroscopy) analysis. SPSS and OMNIC software were used for the data analysis of EI and FTIR respectively. Results: [Table: see text][Table: see text][Table: see text][ Table A , B & C represents descriptive statistics, correlation matrix and component matrix respectively. The multivariate analysis of the FTIR data indicates the significant differences ( P < 0.005) among the different study groups such as normal, OSF and OSCC. The eigen values (normal 0.917, OSF 0.962, OSCC 0.975) from component matrix analysis also indicate the same. Conclusion: The spectroscopic characterization (EI and FTIR) of saliva was effective in evaluating normal and OPMD condition. This noninvasive paradigm can serve as a complimentary technique to the existing gold standard methods for the early detection of oral cancer.

Abstract
Clinical studies have revealed that testosterone supplementation had a positive effect on glucose homeostasis in type 2 diabetes mellitus (T2DM), but did not address how testosterone supplementation affected insulin responsiveness in the liver, a key glucose homeostatic organ. In this study, we aimed to study the effect of testosterone supplementation on hepatic insulin responsiveness and glucose homeostasis through liver in male high-fat diet-induced T2DM mice. Testosterone treatment to T2DM animals showed reduced hepatic glucose output. Testosterone inhibited the insulin signaling in liver, thus increased insulin resistance. However, testosterone treatment inactivated GSK3α independent of PI3K/AKT pathway and inhibited FOXO1 By interaction of androgen receptor to FOXO1 and downregulated PEPCK, causing repression of gluconeogenic pathway, which is otherwise upregulated in T2DM, resulted in better glucose homeostasis.

Abstract
PURPOSE To compare toxicity, compliance, and early response of weekly and 3-weekly cisplatin administration concurrent with radiotherapy as definitive treatment in locally advanced squamous cell carcinoma head and neck. MATERIALS AND METHODS Patients with histologically proven stage III - IV B head and neck carcinoma presenting from June 2013 to March 2014 were randomly assigned to weekly (35 mg/m2, 6 cycles; arm A) and 3 weekly (100 mg/m2, 3 cycles; arm B) cisplatin with concurrent radiotherapy. RESULTS 60 patients were randomly assigned to treatment, 30 in each arm. Median follow-up was 8 months (range 4-13). There was no significant difference in grade 3 mucositis between the two arms (75.9% vs 70%, p = 0.20). Grade 3 neutropenia was more frequent in arm B (55.2% vs 26.7%, p = 0.01). Hypomagnesemia was the commonest electrolyte imbalance and it was significantly higher in arm B (60% vs 20%, p = 0.001). Completion rate of scheduled chemotherapy cycles was higher for patients receiving weekly regimen. Response at 3 months was similar for all the patients {Complete Response (66.7% vs 62.1%), p = 0.200}. Our data suggested that there is a reduced need of hospitalization and supportive care measures for patients receiving weekly cisplatin with RT (p = 0.05). CONCLUSIONS Weekly cisplatin 35 mg/m2 chemotherapy concurrent with radiotherapy is equally effective and less toxic in terms of neutropenia, hypomagnesemia and need for supportive measures than the conventional 3 weekly cisplatin 100 mg/m2 regimen.

Abstract
The spatial and the angular variants of the Imbert-Federov (IF) beam shifts and the angular Goos-Hänchen (GH) shift contribute in a complex interrelated way to the resultant beam shift in partial reflection at planar dielectric interfaces. Here, we show that the two variants of the IF effects can be decoupled and separately observed by weak value amplification and subsequent conversion of spatial ↔angular nature of the beam shifts using appropriate pre and post selection of polarization states. Such optimized weak measurement schemes also enable one to nullify one effect (either the GH or the IF) and exclusively observe the other. We experimentally demonstrate this and illustrate various other intriguing manifestations of optimized weak measurements in elliptical and / or linear polarization basis. We also present a Poincare sphere based analysis on conversion / retention of the angular or spatial nature of the shifts with pre and post selection of states in weak measurement. The demonstrated ability to amplify, controllably decouple or combine the beam shifts via weak measurements may prove to be valuable for understanding the different physical contributions of the effects and for their applications in sensing and precision metrology.

Abstract
BACKGROUND Aminophylline can trigger seizures in patients without known underlying epilepsy or added risk factor for seizure exacerbation in epilepsy. Most of these seizures are difficult to control and are underappreciated compared to other drug toxicities. Despite a long clinical history of aminophylline-induced seizures, relatively little is known about the underlying molecular mechanisms that contribute to methylxanthine-induced seizure generation. OBJECTIVE The present study evaluated the possible involvement of free radicals in aminophylline induced seizures in rat. METHOD The rats were divided into two groups. The first group graded single doses of aminophylline from 100 to 300 mg/kg were administered intraperitoneally. On the basis of the results Aminophylline, a dose (300 mg/kg) producing tonic-clonic seizures and mortality in 100% animals was selected as control in the study. The second group were subjected to single antioxidant (Vitamin E or Vitamin C) or in combination for 45 days then single doses of aminophylline 300 mg/kg administered intraperitoneally to rats. RESULT Aminophylline induced convulsions in rats in a dose-dependent manner, and both incidence of seizure and mortality were maximum at 300 mg/kg and there was significant increase of free radical generation. But though pre-treatment with antioxidants showed differential attenuating effects on aminophylline induced free radical generation as we all known but they were very much ineffective in antagonizing aminophylline induced seizures and post-seizure mortality by any appreciable extent. CONCLUSION Though Aminophylline induces oxidative stress the results are suggestive that at least free radicals is not only cause of convulsiogenic effects and post-seizure mortality of aminophylline.

Abstract
Background: Leiden Score, is a very useful tool for predicting future development of rheumatoid arthritis (RA), among undifferentiated arthritis (UA) patients. This score has been validated in various western studies but rarely among south east Asian patients. Aims: To validate the Leiden early arthritis prediction rule in an Indian cohort of patients for predicting rheumatoid arthritis (RA) in undifferentiated arthritis (UA) patients and to formulate any simpler version of prediction score taking only clinical variables of original Leiden prediction rule. Subjects and Methods: In a group comparative longitudinal study model, 58 patients with early symmetrical polyarthritis were enrolled and baseline evaluation was done according to Leiden prediction rule and then 3 monthly. After 1 year, Leiden prediction score and chance of evolving into RA were calculated. Patients were divided into two groups: Those who developed RA and who did not. They were selected on random sampling process. Tender joint count (TJC), duration of morning stiffness, and duration of arthritis were selected as clinical variables for linear discriminant analysis with disease outcome being the dependent variable. Discriminant scores (D) for each patient was calculated. A receiver operating characteristic (ROC) curve was constructed with the discriminant score and compared with Leiden prediction score. Results: About 54% (27/50) of patients were diagnosed with RA and 46% (23/50) developed other rheumatologic condition or viral inflammatory arthritis or remained undifferentiated or attained complete remission. None of the patients with UA, who scored the regression coefficients 4 or less progressed to RA, and those who scored 7 or more, almost certainly progressed to RA. Unstandardized canonical discriminant coefficients for TJC (T), duration of morning stiffness (M), and duration of arthritis (A) were calculated. ROC curve was plotted with the formula: D = 0.164 × T + 0.066 × M + 0.012 × A − 2.838. Area under curve (AUC) at 95% confidence interval for our discriminant function was 0.845 (standard error [SE] 0.054). In comparison, AUC of Leiden prediction score was 0.897 (SE 0.043). Conclusions: Leiden prediction rule is highly applicable to UA patients to predict progression of RA in Indian patients and larger multi-center study with larger cohorts is needed to validate the formulation we derived to predict RA.

Abstract
The optical analogue of quantum weak measurements has shown considerable promise for the amplification and observation of tiny optical beam shifts, namely Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts. Here, we demonstrate simultaneous weak value amplification of both the angular GH and the IF shifts in partial reflection of a fundamental Gaussian beam at planar dielectric interfaces. We employ pre and postselection schemes with appropriate linear polarization basis states for simultaneous weak measurements and amplification of both of these shifts. The experimentally observed enhancement of the beam shifts and their dependence on the angle of incidence are analyzed/interpreted via theoretical treatment of weak measurements.

Abstract
Quinoline-based small molecules have been explored and being developed as anti-inflammatory agents targeting several pharmacological targets namely Phosphodiesterase 4 (PDE4), Transient Receptor Potential Vanilloid 1 (TRPV1), TNF-α converting enzyme (TACE) and Cyclooxygenase (COX). Efforts on Structure Activity Relationship (SAR) studies revealed that the pharmacological activities and target specificities of these quinoline derivatives were mainly dependent on the nature and position of substituent(s) present on the quinoline ring. For example, quinolines having carboxamide moiety displayed TRPV1 antagonism whereas that with carboxylic acid showed COX-inhibition. Similarly, quinolines possessing aniline moiety at C-4, aryl group at C-8 and oxazole ring at C-5 showed PDE4 inhibition. These quinoline derivatives were synthesized by using various synthetic approaches like Pd-mediated C-C (e.g. Suzuki, Sonogashira type coupling etc.) or C-N (the Buchwald-Hartwig type coupling) or C-S bond formation, AlCl₃ induced C-C bond formation, traditional amide bond formation or amination, formation of ether linkage or additional heterocyclic rings. All these efforts resulted in the discovery of several quinoline-based anti-inflammatory agents for the potential treatment of acute as well as chronic inflammatory diseases.

Abstract
CONTEXT Antracycline-Cyclophosphamide (AC) along with Paclitaxel/Docetaxel, either in combination or sequential regimens, is showing superior results than Anthracycline-containing regimens. AIMS This study was designed to determine whether adding Paclitaxel to a standard adjuvant chemotherapy regimen AC for breast cancer patients would prolong the time to recurrence and survival. SETTINGS AND DESIGN Randomized, prospective, open-labeled, single-institutional study. MATERIALS AND METHODS Fifty stage II breast cancer patients accruing 25 patients in each arm, treated between July 2007 and January 2010, were included in the study. Initial surgical treatment was Modified Radical Mastectomy. Systemic therapy was to have begun within 4-6 weeks of the patient's surgery. In the control arm, all the patients were treated with six cycles of adjuvant chemotherapy with AC regimen repeated at an interval of 3 weeks. For the study arm, the patients received adjuvant chemotherapy with three cycles of AC regimen followed by three cycles of Paclitaxel, repeated at an interval of 3 weeks. All the patients of both the arms received locoregional external beam radiotherapy (EBRT) after the entire course of chemotherapy. All the hormone receptor-positive patients received Tamoxifen. STATISTICAL ANALYSIS USED Statistical analysis was performed using the chi-square test and the Kaplan Meier survival analysis with the log-rank (Mantel-Cox) test. RESULTS Adding Paclitaxel to AC resulted in a statistically significant disease-free survival. The overall survival was also improved significantly. The toxicity profile in both the arms was comparable. CONCLUSIONS In early and node-positive breast cancer, the addition of three cycles of Paclitaxel after completion of three cycles of AC improves the disease-free and overall survival.

Abstract
We demonstrate mode locking of a thulium-bismuth codoped fiber laser (TBFL) operating at 1901.6 nm, using a graphene-based saturable absorber (SA). In this work, a single layer graphene is mechanically exfoliated using the scotch tape method and directly transferred onto the surface of a fiber pigtail to fabricate the SA. The obtained Raman spectrum characteristic indicates that the graphene on the core surface has a single layer. At 1552 nm pump power of 869 mW, the mode-locked TBFL self starts to generate an optical pulse train with a repetition rate of 16.7 MHz and pulse width of 0.37 ps. This is a simple, low-cost, stable, and convenient laser oscillator for applications where eye-safe and low-photon-energy light sources are required, such as sensing and biomedical diagnostics.

Abstract
Epigenetic studies of DNA and histone modifications represent a new and important activity in molecular investigations of human disease. Our previous epigenome-wide scan identified numerous DNA methylation differences in post-mortem brain samples from individuals affected with major psychosis. In this article, we present the results of fine mapping DNA methylation differences at the human leukocyte antigen (HLA) complex group 9 gene (HCG9) in bipolar disorder (BPD). Sodium bisulfite conversion coupled with pyrosequencing was used to interrogate 28 CpGs spanning ∼700 bp region of HCG9 in 1402 DNA samples from post-mortem brains, peripheral blood cells and germline (sperm) of bipolar disease patients and controls. The analysis of nearly 40 000 CpGs revealed complex relationships between DNA methylation and age, medication as well as DNA sequence variation (rs1128306). Two brain tissue cohorts exhibited lower DNA methylation in bipolar disease patients compared with controls at an extended HCG9 region (P=0.026). Logistic regression modeling of BPD as a function of rs1128306 genotype, age and DNA methylation uncovered an independent effect of DNA methylation in white blood cells (odds ratio (OR)=1.08, P=0.0077) and the overall sample (OR=1.24, P=0.0011). Receiver operating characteristic curve A prime statistics estimated a 69-72% probability of correct BPD prediction from a case vs control pool. Finally, sperm DNA demonstrated a significant association (P=0.018) with BPD at one of the regions demonstrating epigenetic changes in the post-mortem brain and peripheral blood samples. The consistent multi-tissue epigenetic differences at HCG9 argue for a causal association with BPD.

Abstract
Histamine H(1) receptor antagonists play a vital role in the first line treatment of a broad range of allergic diseases. Frequent dosing of the antagonist results in side effects like sedation and cardiovascular toxicity. The present study highlights the important structural requirement and mechanistic interpretation of novel indolylpiperidinyl derivatives as H(1) receptor antagonists so as to facilitate the design of newer antihistaminics with increased duration of action and comparatively reduced side effects. The significance of the developed quantitative structure-activity relationship (QSAR) models were evaluated on the basis of statistical values of square of correlation coefficient (r(2)); (multiple linear regression (MLR), 0.86; and partial least squares (PLS), 0.85). The predictive ability of the resulting QSAR models was evaluated with cross-validated correlation coefficient (r(2)cv) values (MLR, 0.82; PLS, 0.82) generated for the training set and r(2) values (MLR, 0.763; PLS, 0.855) derived for test set. The final models comprised of multidimensional steric (verloop length, verloop B(3)), electronic (total dipole moment) and steric (KAlpha1 index) descriptors. The study indicates that antihistaminic activity is largely explained by steric and electronic parameters. In line with parameters entered in the model some indolylpiperidines derivatives were designed with good antihistaminic properties and pharmacokinetic profiles.

Abstract
INTRODUCTION The aims of the study are (i) to understand inter-zone and interstate variation of low birth weight (LBW) and (ii) to determine the key variables to reduce LBW in India. METHODS Using the latest National Family Health Survey (NFHS) data of 2005-06 which showed the percentage distribution of LBW infants, ANOVA and post-hoc test were performed to determine the spatial variation of birth weight. The covariates which influence LBW fell into three categories: (i) social variables which included location, mother's education, religion, access of mothers to newspapers, television and family structure; (ii) economic variable namely, the wealth index, and (iii) biological variables which consisted of sex of the children, birth order, and mother's body mass index (BMI). Three models of Logistic regression were carried out to examine the influence of the combinations of these direct and indirect factors. RESULTS In India, nearly 20% of new borns have LBW. Males have less frequency of LBW than females. The North-east zone has the lowest prevalence of LBW while the north zone has the highest. Mother's education, access to TV and nuclear family, and intake of iron tablets are the most important socio-economic influences on the determination of birth weight in India. CONCLUSION It is essential to provide proper diet and nutritional care of mothers during pregnancy. Increased education of mothers through programmes in TV and newspapers articles have significant roles to play in reducing LBW in India.
