RESUMO
BACKGROUND: Serum adipokines (leptin and adiponectin) are dysregulated before the onset of metabolic syndrome and hence may be useful biomarkers for screening of cardiometabolic late effects in childhood Acute Lymphoblastic Leukemia (cALL) survivors. METHODS: We compared serum adipokine levels between 40 cALL survivors (aged 10-18 years, >2 years from treatment completion) with similar controls. A multivariable logistic regression analysis was then done to assess the association of metabolic syndrome in cALL survivors with variables including adipokines and other metabolic parameters, demographic and treatment details, and Dual-energy X-ray absorptiometry scan-derived variables. RESULTS: Compared to controls, cALL survivors had a higher prevalence of metabolic syndrome (8/40 vs. 2/40, P = .044) and central obesity (11/40 vs. 4/40, P = 0.042). Median Serum Leptin (7.39 vs. 4.23 ng/ml, P = 0.207) levels and derived Leptin-Adiponectin Ratio (1.44 vs. 0.80, P = 0.598), were higher but not statistically different in our survivors compared to controls; Adiponectin levels were similar (6.07 vs. 5.01 µg/ml, P = 0.283). In the cALL survivors, overweight/obesity (odds ratio [OR] 21.9, P = 0.020) or higher Leptin levels (OR 1.11, P = 0.047), were independently associated with metabolic syndrome. CONCLUSIONS: Serum Leptin, independently predictive of metabolic syndrome in our cALL survivors, may be tested in larger studies to assess its utility in surveillance and initiation of early preventive measures.

INTRODUCTION: Atherosclerosis has been shown to impact cognitive impairment, with most of the evidence originating from European, African, or East Asian populations that have employed carotid intima-media thickness (cIMT) as a biomarker for atherosclerosis. Vascular disease is related to dementia/cognitive decline. There is no community-based study from India that has looked at the association of cIMT with cognitive performance. METHODS: In this cross-sectional study between December 2014 and 2019, we recruited 7505 persons [(mean age 64.6 (9.2) y) and 50.9% women] from a community-dwelling population in New Delhi. These persons underwent carotid ultrasound to quantify cIMT and a cognitive test battery that tapped into memory, processing speed, and executive function. We also computed the general cognitive factor (g-factor), which was identified as the first unrotated component of the principal component analysis and explained 37.4% of all variances in the cognitive tests. We constructed multivariate linear regression models adjusted for age, sex, education, and cardiovascular risk factors. Additional adjustment was made for depression, anxiety, and psychosocial support in the final model. RESULTS: We found a significant association of higher cIMT with worse performance in general cognition (ß=-0. 01(95% CI: -0.01; -0.01); P<0.001), processing speed (ß=-0.20; 95% CI: -0.34; -0.07); P=0.003), memory (ß=-0.29; 95% CI: -0.53; -0.05); P=0.016), and executive function (ß=-0.54; 95% CI: -0.75; -0.33); P=<0.001). There was no statistically significant association of cIMT with Mini-Mental Status Examination score (ß=0.02; 95% CI: -0.34; 0.40; 0.89). CONCLUSION: The cross-sectional study found significant associations of increased cIMT with worse performance in global cognition, information processing, memory, and executive function.

STUDY OBJECTIVES: To determine if metabolic risk factors are associated with poor sleep quality and obstructive sleep apnea-like symptoms (OSA symptoms) independent of psychosocial problems and demographic and lifestyle factors in older Indian adults. METHODOLOGY: We analyzed baseline data from adults (≥ 50 years) from a population-based cohort, the LoCARPoN study, in India. Variables were grouped as (a) demographic and lifestyle factors such as smoking, alcohol use, and physical activity; (b) psychosocial problems including symptoms of depression, anxiety, and perceived stress; and (c) metabolic risk factors including glycated hemoglobin, high-density lipoprotein, low-density lipoprotein, total cholesterol, body mass index, and hypertension. Variables were examined as predictors of poor sleep quality and OSA symptoms. Groups of variables were added stepwise to a logistic regression. Variance explained by nested models was quantified using McFadden's pseudo R2, and change was formally tested with the log-likelihood ratio test. RESULTS: Among 7505 adults, the prevalence of poor sleep quality was 16.9% (95% CI: 16.0, 17.7), and OSA symptoms were present in 7.0% (95% CI: 6.4, 7.6). Psychosocial problems had a strong independent association with both poor sleep quality (pseudo R2 increased from 0.10 to 0.15, p < 0.001) and more OSA symptoms (pseudo R2 increased from 0.08 to 0.10, p < 0.001). Metabolic risk factors had a modest independent association with sleep quality (pseudo R2 increased from 0.14 to 0.15, p < 0.01), but a strong association with OSA symptoms (pseudo R2 increased from 0.08 to 0.10, p < 0.001). CONCLUSION: Psychosocial and metabolic risk factors were independently associated with sleep quality and OSA symptoms. This fact implied that OSA symptoms may affect both mental health and physical health. Our findings have public health implications because the number and proportion of the elderly in India is increasing, while the prevalence of metabolic risk factors and psychosocial problems is high already. These facts have the potential to exacerbate not only the burden of sleep disorders and OSA symptoms but also associated cardiovascular and neurologic sequelae, further stretching the Indian health-care system.

INTRODUCTION: Symptoms of obstructive sleep apnea (OSA) and poor sleep quality affect around one in ten people in India. We aimed to determine if OSA symptoms and poor sleep quality are independently associated with cognition in middle-aged and elderly urban Indian populations. METHODS: We studied the cross-sectional association between OSA symptoms (by Berlin Questionnaire), poor sleep quality (by Pittsburgh Sleep Quality Index), and cognitive function in adults ≥ 50 years. Using a standard neuropsychological battery for cognitive function, a G-factor was derived as the first rotated principal component assessing domains of information processing, memory, and executive function. The associations of exposures with cognitive measures were modeled using linear regression, adjusted for metabolic risk factors, lifestyle factors, and psychosocial problems, followed by stratified analysis by decadal age group. RESULTS: A total of 7505 adults were enrolled. Excluding those with MMSE < 26 (n 710), of 6795 individuals (49.2% women), mean (SD) age 64.2 (9.0) years, 38.3% had high risk of OSA symptoms, and 15.9% had poor sleep quality. OSA symptoms were negatively associated with cognitive domains of information processing (adjusted beta coefficient of z-score - 0.02, p-value 0.006), memory (- 0.03, 0.014), and G-factor (- 0.11, 0.014) in full-model. Stratified analysis by age group showed significant adverse effects of OSA symptoms on cognition for middle-aged people (50-60 years) (- 0.26, 0.001), but not in later age groups. Poor sleep quality was also associated with lower cognitive scores for G-factor (- 0.48, < 0.001), memory (- 0.08, 0.005), and executive domains (- 0.12, < 0.001), but not with information domain. CONCLUSION: The findings suggest that both symptoms of OSA and poor sleep quality have a direct adverse impact on cognition in an Indian setting. A modest effect of age on the relationship of OSA and cognition was also observed.
RESUMO
Bacterial vaginosis (BV) is diagnosed by the microbiological Nugent scoring method or clinical Amsel's criteria. Assessment of 404 vaginal samples (293 women) identified 110 (27.2%), 108 (26.7%) and 161 (39.9%) samples to be BV-positive using Nugent's method, standard Amsel's criteria and simplified Amsel's criteria respectively. The sensitivity, specificity, and kappa statistic (κ) for standard and simplified Amsel's criteria were 71.8% (95% CI=62.4-80.0), 90.1% (95% CI=62.4-86.1), 0.62 (95% CI=0.53-0.72) and 88.2% (95% CI=80.6-93.6), 78.2% (95% CI=73.1-82.8), 0.58 (95% CI=0.49-0.67), respectively. A combination of vaginal pH and clue cells exhibited the highest concordance (κ=0.64, 95% CI=0.54-0.74) with Nugent's method and may be used for simplified BV diagnosis.

Objectives: Given the known side effects of opioids and the negative impact of these side effects on quality of life (QOL), there is a need for therapies that can reduce opioid intake and improve QOL in patients suffering from cancer pain. Scrambler therapy (ST) is a neuromodulatory therapy that has been shown to reduce cancer pain, but its effect on QOL is not well understood. This study intended to evaluate the efficacy of ST for enhancing QOL in cancer patients through minimising pain and opioid intake. Material and Methods: This was a randomised controlled trial including 80 patients with head, neck and thoracic cancer. In both arms, patients were given pain management drugs following the WHO analgesic ladder for ten consecutive days. In the intervention arm each day ST was given. Pain, morphine intake, and QOL (WHOQOL-BREF) were assessed. Results: All domains of QOL improved significantly in the intervention arm in comparison to the control arm. In comparison to baseline, pain improved in both the intervention and the control arm on day 10 and at follow-up. However, QOL significantly improved in the intervention arm, while morphine intake decreased. In the control arm, QOL deteriorated, while morphine intake increased. Conclusion: ST significantly improved QOL. Since the increase in QOL took place along with a significantly lower morphine intake, the improvement in QOL may not only be explained by lower pain scores but, also, by a reduced intake of morphine, because the lower dosages of morphine will decrease the likelihood of side effects associated with the drug.
RESUMO
BACKGROUND: Clinical breast examination (CBE) is an integral component of triple assessment for women presenting with symptomatic breast disease. Four common search patterns of CBE are "dial of a clock" (DC), "vertical strips" (VS), "quadrant-wise" (QW), and "concentric circles" (CC). The most sensitive search pattern of CBE has not been established. METHODS: A cross-sectional study was conducted on women with symptomatic breast disease, to measure various diagnostic performance indices of four different search patterns of CBE by a professor, a surgical resident trainee, and a trained nurse. Women were examined one at a time randomly by three examiners. Each examiner examined with four different search patterns of CBE, one method at a time. Any nodularity or lump detected was noted and the findings were compared with breast sonography, which was considered as the gold standard. Statistical analysis was done using STATA 14, SPSS 20, and OpenEpi software for diagnostic test indices. RESULTS: Sixty women (mean age = 39.6) with palpable findings of both breasts were included (n = 120). Most women presented with complaints of breast lump (70%) and mastalgia (27%). Sensitivity was highest for DC as elaborated [% (95% confidence interval)]: DC[73.2 (60-83)] > CC[66 (53-77)] > VS[62.5 (49-73)] > QW[58.9 (45-70)] for professor; DC[64.2 (51-75)] > VS[62.5 (49-73)] > CC[57.1 (44-69)] > QW[57.1 (44-69)] for resident; and DC[82.1 (70- 90)] > VS[78.5 (66-87)] > CC(75 (62-84)] > QW[73.2 (60-83)] for nurse. The minimum sonographic tumor size picked up by DC by all the examiners was 7 mm. CONCLUSIONS: The DC search pattern of CBE demonstrated the highest sensitivity for all the examiners. The trained nurse achieved the highest sensitivity among all the examiners.

Functional network changes associated with Braille reading are different in early blind (EB) and late blind (LB) participants. The objectives were to study the functional connectivity (of memory and language areas based on blood oxygen level-dependent [BOLD] mapping) and structural changes in EB and LB children and adolescents. A total of 110 participants (all right-handed) were recruited in two age groups of 6-12 years (children) and 13-19 years (adolescents) consisting of EB (n = 20), LB (n = 20), and sighted controls (SC, n = 15) in each group. Group differences were estimated between children and adolescent groups. Structural changes in visual cortex and medial temporal area, increased BOLD activations and altered functional connectivity in the primary visual cortex, inferior frontal gyrus, middle temporal gyrus, and hippocampus during Braille reading task were observed in adolescents as compared with children blind groups (pFDR corrected <0.05). Functional results were positively correlated with duration of Braille reading and age at onset in EB and LB groups (p ≤ 0.01). Visual, language, and learning memory networks were different in adolescents and children of both EB and LB groups, and also between EB and LB groups suggesting cross-modal plasticity. The functional and structural results revealed education dependent cross-modal plasticity in visually impaired participants. Memory and language network were affected more in the LB group than the EB group, and more in children than adolescents.
RESUMO
BACKGROUND: Oral cancer is the most common cancer among Indian men, and has strong tendency of metastatic spread to neck lymph node which strongly influences prognosis especially 5 year survival-rate and also guides the related managements more effectively. Therefore, a reliable and accurate means of preoperative evaluation of extent of nodal involvement becomes crucial. However, earlier researchers have preferred to address mainly its dichotomous form (involved/not-involved) instead of ordinal form while dealing with epidemiology of nodal involvement. As a matter of fact, consideration of ordinal form appropriately may increase not only the efficiency of the developed model but also accuracy in the results and related implications. Hence, to develop a model describing factors associated with ordinal form of nodal involvement was major focus of this study. METHODS: The data for model building were taken from the Department of Surgical Oncology, Dr.BRA-IRCH, AIIMS, New Delhi, India. All the OSCC patients (duly operated including neck dissection) and confirmed histopathologically from 1995 to 2013 were included. Further, another data of 204 patients collected prospectively from 2014 to 2015 was considered for the validation of the developed model. To assess the factors associated with extent of nodal involvement, as a first attempt in the field of OSCC, stepwise multivariable regression procedure was used and results are presented as odds-ratio and corresponding 95% confidence interval (CI). For appropriate accounting of ordinal form, the ordinal models were assessed and compared. Also, performance of the developed model was validated on a prospectively collected another data. RESULTS: Under multivariable proportional odds model, pain at the time of presentation, sub mucous fibrosis, palpable neck node, oral site and degree of differentiation were found to be significantly associated factors with extent of nodal involvement. In addition, tumor size also emerged to be significant under partial-proportional odds model. CONCLUSIONS: The analytical results under the present study reveal that in case of ordinal form of the outcome, appropriate ordinal regression may be a preferred choice. Present data suggest that, pain, sub mucous fibrosis, palpable neck node, oral site, degree of differentiation and tumor size are the most probable associated factors with extent of nodal involvement.

OBJECTIVE. Several clinical studies have shown the efficacy of 177Lu-labeled prostate-specific membrane antigen (PSMA) radioligand therapy (RLT) for metastatic castration-resistant prostate cancer (mCRPC). The purpose of this article is to present results of a systematic review and meta-analysis aimed at compiling and outlining efficacy and safety data on 177Lu-PSMA RLT for mCRPC across all studies published to date. CONCLUSION. The results of the systematic review and meta-analysis suggest that 177Lu-PSMA RLT is an effective treatment of advanced-stage mCRPC that is refractory to standard therapeutic options and that it has a low toxicity profile. High-level evidence from randomized control trials is crucial for confirming the effectiveness of 177Lu-PSMA RLT and for instituting this therapy in the routine clinical care of patients with mCRPC.

BACKGROUND AND AIM: Celiac disease (CeD) is a common autoimmune disorder in which ingestion of gluten and related proteins leads to inflammation in the small intestine. Although the histological findings in CeD are characteristic, they are not specific. In this study, proton nuclear magnetic resonance (NMR) spectroscopy was used to investigate the differences in metabolic profile of duodenal mucosal biopsies of patients with CeD and controls to find out the biomarker/s of villous atrophy. METHODS: Duodenal mucosal biopsies were collected from 29 CeD patients (mean age 26.2 ± 10.8 years) and 17 controls (mean age 34.1 ± 11.1 years) and were subjected to proton NMR spectroscopy following perchloric acid extraction. Assignment of metabolite resonances was carried out and their concentrations were determined. For comparison between the groups unpaired t-test/Wilcoxon rank sum test was used. Partial least squares-discriminant analysis was performed to study the clustering behavior of the samples from CeD patients and controls using the Unscrambler 10.2 software. RESULTS: Partial least squares-discriminant analysis clearly differentiated CeD patients from controls. Significantly higher concentrations of isoleucine, leucine, aspartate, succinate, and pyruvate, and lower concentration of glycerophosphocholine, were observed in the duodenal mucosa of CeD patients compared with controls. The results suggest abnormalities in glycolysis, Krebs cycle (energy deficiency), and amino acid metabolism, which may affect the biosynthetic pathways and consequently contribute to villous atrophy. CONCLUSIONS: NMR spectroscopy with multivariate analysis of duodenal mucosal biopsies revealed a characteristic metabolic profile in CeD patients. The work provided an insight in determining biomarker/s for villous atrophy and diagnosis of CeD patients.

SCOPE: Association between vitamin B12 deficiency (VB12D) and dietary patterns being well documented has bearing on obstetrics and neonatal outcomes. However, relationship between VB12D and serum inflammatory markers (IMs), particularly in vegetarian diet and Polycystic ovary syndrome (PCOS), remains elusive. This cross-sectional study assesses VB12D and IMs among reproductive age women consuming different diets. METHODS AND RESULTS: Nonvegetarian (PCOS, n = 104; healthy, n = 148) and vegetarian women (PCOS n = 112; healthy, n = 186) are for evaluated clinical, biochemical, hormonal assessment, inflammatory, and four vitamin B 12 (VB12) markers. VB12D is defined by Fedosov's wellness quotient (4cB12). Using 4cB12, prevalence of VB12D is discerned in 54.4% (PCOS: 72.1%; healthy 36.5%) and 93.4% (PCOS: 95.9%; healthy: 91.9%) among nonvegetarians and vegetarians, respectively. Vegetarian PCOS women depict lowest median (interquartile range [IQR]) of serum B12 76.2(72.6) pg mL-1, holotranscobalamine (HTC) 37.9(11.3) and highest homocysteine (HCY) 40.32(6.0) µmol L-1, methylmalonic acid (MMA) 352.26(156.7) nmol L-1 with highest Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and IMs (Monocyte chemoattractant protein 1 (MCP-1), High sensitivity C-reactive protein (hs-CRP), Tumour Necrosis Factor alpha (TNF-α) and Interleukin 6 (IL-6)). Significant correlation of serum hs-CRP, TNF-α, and IL-6 with VB12 markers is observed. CONCLUSION: The VB12D is rampant among reproductive age women that gets exacerbated by PCOS or vegetarian diet. It is directly correlated with magnitude of proinflammatory markers. The results carry substantial implications for public health policies aimed at improving preconception maternal VB12 status for better future pregnancy and offspring outcomes.

Objective: Syncope is a common clinical condition in the elderly, associated with significant morbidity and risk of recurrence. Recurrent syncope causing a repeated reduction in the cerebral blood flow can predispose to progressive neurodegeneration, a decline in overall health and functionality. Hence, this study was conducted to study the common causes of recurrent syncope and its association with various geriatric syndromes. Methodology: This case-control study recruited 50 cases of recurrent syncope and 50 controls, aged 75 years and older. A detailed history and sequential evaluation for aetiologies of recurrent syncope were done. Cognition, frailty, activities of daily living, depression, and nutrition were assessed using various scales. Results: Most (80%, 80/100) of the participants were males and the mean age was 80.04 ± 4.3 years. In the syncope group, 42% (21/50) of patients had arrhythmia, and 30% (15/30) had valvular heart disease. Recurrent syncope was significantly associated with lower scores on Montreal cognitive assessment scale (OR: 6.47 P < 0.001), four or more comorbidities (OR: 6.29 P < 0.001), and hearing impairment (OR: 6.21 P < 0.004) on multivariate logistic regression analysis. Conclusion: Recurrent syncope is significantly associated with cognitive impairment, the presence of four or more comorbidities, and hearing impairment. Conduction abnormality was the most common etiology of recurrent cardiovascular syncope. Structured evaluation and appropriate management of recurrent syncope might reduce the decline in physical, cognitive, and psychological reserve. A follow-up longitudinal study is needed to establish this.
RESUMO
Background: Parkinson's disease (PD) is a progressive disorder with alterations in cortical functional activity. Transcranial magnetic stimulation is known to incur motor benefits in PD by inducing motor activity through cortical connectivity, although the mechanisms are unclear. Objective: The effects of repetitive transcranial magnetic stimulation (rTMS) (at three cortical sites) on functional and structural plasticity were studied in PD to understand inhibitory or excitatory rTMS-induced motor improvement. Methodology: The study was a single blind, randomized, sham-controlled type involving three groups. Three thousand rTMS pulses of frequency 1 Hz were given at primary motor area (in 13 patients of Group A) or premotor area (in Group B, n = 18) and a frequency 5 Hz at supplementary motor area in Group C (n = 19). Clinical rating scores (Unified Parkinson's Disease Rating Scale [UPDRS], Parkinson's Disease Questionaire-39 [PDQ-39]) and motor dexterity were assessed at baseline, after sham and real rTMS sessions. Visuospatial functional magnetic resonance imaging task along with T1-weighted scans (at three Tesla) were used to evaluate the motor execution and planning post rTMS intervention. Results: Improvements (p < 0.05) in UPDRS II, III, Mobility, and activities of daily living of PDQ-39, Purdue Pegboard were observed. Increased blood oxygen level-dependent (BOLD) activations (family-wise error [FWE]-corrected P-value [pFWE] <0.01) were observed in motor cortices, parietal association areas, and cerebellum in groups C and decrease in group A and B after real TMS as compared with sham. Conclusions: Repetitive TMS at motor (1 Hz) and supplementary motor (5 Hz) areas resulted in significant clinical benefits by inducing cortical plasticity. Impact statement TMS daily protocols have been commonly employed to modulate cortical connectivity in Parkinson's disease (PD). This study uses functional magnetic resonance imaging to assess rTMS-related effects in PD. Repetitive TMS protocol at higher pulses (3000/session) in primary and supplementary motor cortices administered weekly was clinically effective and safe. The results revealed functional restoration along with cortical plasticity mechanisms of externally generated movement in PD in response to noninvasive brain stimulation.

Population-based prospective cohort studies can yield vital new evidence. However, they are difficult to setup especially in non-western contexts such as India. We describe our experience in establishing the Longitudinal Cognition and Aging Research on Population of the National Capital Region (LoCARPoN) cohort, which was the first-of-its-kind public-funded study with target sample size of 15,000, 3 sites, and funds of approx. US$ five million for eight years (2014-2022). LoCARPoN aimed to study incident stroke and dementia in adults aged ≥50 years in urban and rural populations of north India. Among the numerous challenges encountered, important were inadequate funding, lack of adequate space for medical and field sites, difficulty in hiring manpower, lack of IT infrastructure, non-availability of storage facility for biological samples, and absence of dedicated MRI machines. Meticulous planning, adequate funding, trained personnel, institutional and community support are critical for establishing such cohorts in the non-western contexts. Funding: The LoCARPoN cohort study was funded by the Department of Biotechnology (Grant No. BT/IN/Netherlands/03/KP/2012 dated 14/02/2014); and Department of Health Research (Grant No. R.11012/15/2018-HR, dated 09/08/2018), Government of India. The Erasmus component was funded through the Erasmus Medical Centre, Rotterdam, The Netherlands, and the Erasmus University, Rotterdam (Alzheimer NederlandWE.15-2014-09).
RESUMO
INTRODUCTION: Corticosteroids are used as adjunctive treatment in tuberculous meningitis (TBM). However, there is no universally accepted regimen, type, duration, or route of steroid administration. METHODOLOGY: In a randomized open labelled pilot study, TBM patients were divided into overlap oral dexamethasone (OOD) and direct oral dexamethasone (DOD) arms. The total duration of steroid administration was 8 weeks. The primary outcome was symptomatic resolution at 1 month post randomization. The secondary outcomes were mortality and modified Rankin scale (mRS) at 3 and 6 months after initiation of steroids. RESULTS: Symptomatic resolution after one month of randomization in 53 randomized patients was similar in OOD (71.4% (15/21)) versus DOD ((85.0% (17/20)) arm (p value:0.45). Median mRS was also similar in OOD versus DOD (OOD: 2.5 (IQR: 1.0; 6.0) versus DOD: 1.0 (IQR: (0.0; 4.0); p value: 0.31)) arm at 6 months. The mortality at 6 months was 31.8% (7/22) in the OOD versus 20.0% (4/20) in the DOD arm (p value: 0.49). CONCLUSIONS: In this open label pilot study, the outcomes were similar in OOD versus DOD arms in terms of symptomatic resolution at 1 month, and morbidity, and mortality at 3 and 6 months. Patients with stage I to III TBM may be given injectable steroids for 1 week after which they may be switched to oral steroid. This regime cannot be applied to stage IV TBM and patients with complications like optico-chiasmatic or spinal arachnoiditis or vasculitic infarcts.

INTRODUCTION: Auditory perception and associated cognition involve visual and auditory cortical areas for inference of meaningful soundscape. OBJECTIVE: To investigate auditory perception of ambiguous and non-ambiguous stimulation in auditory and visual cortical networks for categorical discrimination. METHODOLOGY: Functional mapping was carried out in twenty early (EB), twenty late blind (LB) and fifteen healthy children, during auditory ambiguous and non-ambiguous stimulation task in a 3 T MR scanner to estimate hemodynamic signal alteration and its effect on functional connectivity. The degree of amplitude low-frequency fluctuation (ALFF), correlation analysis and multiple comparison was carried out to map the impact of duration of education and onset of blindness (EB and LB). RESULTS AND DISCUSSION: Increased functional connectivity (FC) and cross-modal reorganization was observed in auditory, visual and language networks in EB children. FC was increased in contralateral hemisphere in both the blind children (EB and LB) groups and was positively correlated with duration of education performance. Cognitive assessment scores correlated (p < 0.01) with cluster coefficient of FC and BOLD response. CONCLUSION: FC alterations depend on onset age and audio-haptic training in children associated with increased auditory language and memory perception.

Questionnaires were developed using 5 steps: item generation by literature review and preexisting questionnaires, expert evaluation, pilot testing, factor analysis, and internal consistency. SETTING: Adults with obesity recruited via web-based survey hyperlink. PARTICIPANTS: One hundred participants with a mean body mass index of 28.7 ± 4.4 kg/m2. VARIABLES MEASURED: The questionnaires were generated using 221 items. Establishing content, face and construct validity, and internal consistency. ANALYSIS: Content validity was analyzed using content validity index and content validity ratio, internal consistency through Cronbach α (CA), and structural validity by factor analysis via principal varimax rotation. RESULTS: All three questionnaires had good content validity. The Behavioral Predictor Questionnaire had good internal consistency (CA, 0.7) and excellent structural validity (69.7%). Psychosocial Predictors Questionnaire (CA, 0.8, 67.5%) and Environmental Predictors Questionnaire (CA: 0.8, 72.2%) had excellent internal consistency and structural validity. CONCLUSION AND IMPLICATION: Questionnaires seem to be practical, valid, and reliable tools for baseline assessment of individual-specific factors related to weight loss success.

BACKGROUND AND AIMS: This study aims to identify the barriers and facilitators faced by obese patients with NAFLD from north India, while undergoing lifestyle-modification. METHODS: 30 obese patients with NAFLD were interviewed regarding the barriers and facilitators to lifestyle change and responses were noted. Inductive thematic analysis was used. RESULTS: Eight themes under barriers (lack of family support, difficult intervention, work-related, financial, psychological, social, physical and infrastructure related) and four themes under facilitators (family support, intensive nature of intervention, psychological and physiological) were identified from the reponses. CONCLUSIONS: Personalized and socio-culturally appropriate counseling strategies may promote successful treatment outcomes among these patients.

CONTEXT: While analyzing locoregional recurrences (LRRs), it is necessary to consider distant metastasis as a competing event. Because, later one is more fatal than LRR. It may change ongoing treatment of breast cancer and may alter the chance of LRR. Although some earlier studies assessed the effect of neoadjuvant chemotherapy (NACT) on LRR, they did not use competing risk regression model for it. AIMS: To identify the risk factors and predict LRR using competing risk hazard model and to compare them with those using conventional hazard model. SETTINGS AND DESIGN: This was a retrospective study from a tertiary care cancer hospital in India. SUBJECTS AND METHODS: Data of 2114 breast cancer patients undergoing surgery were used from patient's record files (1993-2014). STATISTICAL ANALYSIS: Fine and Gray competing risk regression was used to model time from surgery to LRR, considering distant metastasis and death as the competing events. Further, cause-specific Cox regression was used to model time from surgery to LRR without considering competing risk. RESULTS: Greater than ten positive nodes (hazard ratio [HR] [95% confidence interval (CI)]: 2.19 [1.18-4.03]), skin involvement (HR [95% CI]: 2.75 [1.50-5.05]), NACT (HR [95% CI]: 1.90 [1.06-3.40]), invasive tumor in inner quadrant (HR [95% CI]: 1.78 [0.98-3.24]), and postoperative radiotherapy (HR [95% CI]: 0.52 [0.29-0.94]) were found to be significantly associated with LRR. However, conventional survival analysis ignoring competing risk overestimated cumulative incidence function and underestimated survival. Competing risk regression provided relatively more precise CI. Conclusions: Competing risks, if any, need to be incorporated in the survival analysis. NACT was found to be associated with higher risk for LRR, which may be because of administering it mainly to patients with bad prognosis. CONCLUSIONS: Competing risks, if any, need to be incorporated in the survival analysis.
