    311-322Elettaria cardamomum Maton the small cardamom of commerce is a monotypic genus in India under the family Zingiberaceae. Genetic diversity studies using inter simple sequence repeat (ISSR) markers were conducted on a total of 13 released varieties of cardamom including selections and hybrids from different research stations in South India along with a popular variety Njallani and a wild relative Aframomum sps as checks. ISSR markers however, revealed relatively high level of genetic redundancy among the tested varieties with the exception of a few. Nonetheless, unweighted pair group method of arithmetic average (UPGMA) based cluster analysis of the similarity matrix differentiated all the varieties tested with the exception of two and segregated the wild relative Aframomum. Considerable reduction of polymorphism percentage was observed on exclusion of Aframomum while studying ISSR polymorphism which could be an indicator of the narrowing genetic base in the released varieties. Morphological data were compiled based on International Plant Genetic Resources Institute (IPGRI) cardamom descriptor and revealed moderate variability among the varieties. The results highlighted the requirement of molecular characterization of unutilized germplasm accessions, related wild species, and exotic relatives using specific molecular markers to help refine breeding efforts and introgression of new alleles for further improvement and enhancement of genetic base of cultivated cardamom

    Animal models of human behavioral endophenotypes, such as the Tail Suspension Test (TST) and the Open Field assay (OF), have proven to be essential tools in revealing the genetics and mechanisms of psychiatric diseases. As in the human disorders they model, the measurements generated in these behavioral assays are significantly impacted by the genetic background of the animals tested. In order to better understand the strain-dependent phenotypic variability endemic to this type of work, and better inform future studies that rely on the data generated by these models, we phenotyped 33 inbred mouse strains for immobility in the TST, a mouse model of behavioral despair, and for activity in the OF, a model of general anxiety and locomotor activity.We identified significant strain-dependent differences in TST immobility, and in thigmotaxis and distance traveled in the OF. These results were replicable over multiple testing sessions and exhibited high heritability. We exploited the heritability of these behavioral traits by using in silico haplotype-based association mapping to identify candidate genes for regulating TST behavior. Two significant loci (-logp >7.0, gFWER adjusted p value <0.05) of approximately 300 kb each on MMU9 and MMU10 were identified. The MMU10 locus is syntenic to a major human depressive disorder QTL on human chromosome 12 and contains several genes that are expressed in brain regions associated with behavioral despair.We report the results of phenotyping a large panel of inbred mouse strains for depression and anxiety-associated behaviors. These results show significant, heritable strain-specific differences in behavior, and should prove to be a valuable resource for the behavioral and genetics communities. Additionally, we used haplotype mapping to identify several loci that may contain genes that regulate behavioral despair

    Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

    No full text
    Background & objectives: Prognosis of patients with multiple myeloma (MM) has improved significantly in the past two decades. However, the symptoms burden is high at onset and treatment is generally prolonged with significant financial burden. This study was undertaken to assess the quality of life (QoL) and to analyse out-of-pocket expenditure (OOPE) incurred on MM patients being treated at a tertiary care cancer centre in north India. Methods: This observational, cross-sectional study included 116 patients (aged >18 yr) of MM (both newly diagnosed and those with recurrent disease). For QoL assessment, European Organisation for Research and Treatment of Cancer (EORTC)-validated questionnaire (EORTC QLQ C 30 version 3.0) and disease-specific QLQ MY20 were used. For assessing OOPE incurred on treatment, the National Sample Survey Organisation (NSSO) questionnaire was used. Results: Bone pains (68.1%), fatigue (59.7%) and dyspnoea (54.6%) were common symptoms. The mean global health status/QoL score was 59.62±19.21. International Staging System (ISS) score correlated with global health status score, and gastritis was the main adverse effect. QoL score showed negative correlation to side effects of treatment (−0.53) of MY20 domain. On multivariate analysis, ISS stage (P<0.001) and adverse effects of treatment (P=0.02) were predictive factors. The median OOPE was ₹ 7900 (IQR, ₹ 4950-13,550) towards medical and ₹ 1150 (IQR, ₹ 500-3100) for non-medical expenses for the past one month. Interpretation & conclusions: Regular assessment of QoL in the clinical management of multiple myeloma patients has the potential of improving treatment outcomes. Measures to reduce out-of-pocket expenditure may improve treatment compliance

    INTRODUCTION: Osteoporosis is a chronic, progressive metabolic bone disease characterized by low bone mass and structural deterioration of bone tissue, leading to increased bone fragility. Bone loss increases after menopause due to lower levels of estrogen. Objectives: Evaluate the effectiveness of structured teaching programme on knowledge regarding prevention of osteoporosis among post-menopausal women. Methodology:  Pre experimental one group pre-test post-test design was adopted. The study was conducted on 30 post-menopausal women residing in Enadimangalam PHC. The samples were selected by purposive sampling. Data were collected by structured knowledge questionnaire to assess the existing level of knowledge of post menopausal women regarding prevention of osteoporosis, followed by structured teaching programme was given, after 5 days post test was conducted by using same knowledge questionnaire. Results: The present study results revealed that  mean posttest score was improved from 9.63 to 18.27 with mean difference 9.34,which is statistically significant (p <0.05).‘t’ value was significant. Among the samples the mean post test scores on knowledge regarding prevention of osteoporosis among post menopausal women (18-97) was more than that of the mean pre test scores (9.63). This implies that the knowledge level had improved after STP. Conclusion: The findings of the study revealed that structured teaching programme on prevention of osteoporosis helped to improve the level of knowledge among post menopausal women

    Oral field cancerization and its clinical implications in the management in potentially malignant disorders

    No full text
    Oral cancer is one of the common malignancies reported in India. Most of these cancers are preceded by potentially malignant disorders. Despite improvements in the management strategies of these cancers the posttreatment prognosis has remained poor. The 5-year survival rates of oral cancers in most countries are still below 50%. The poor outcomes in oral cancer prevention and treatment can be due to nature of the spread of genetically altered cells as fields within the epithelial compartment. The conventional management protocols need to be modified taking into consideration the field spread of genetically altered cells

    Intersecting social determinants of health among patients with childcare needs: a cross-sectional analysis of social vulnerability

    Abstract Introduction Access to childcare is an understudied social determinant of health (SDOH). Our health system established a childcare facility for patients to address childcare barriers to healthcare. Recognizing that social risk factors often co-exist, we sought to understand intersecting social risk factors among patients with childcare needs who utilized and did not utilize the childcare facility and identify residual unmet social needs alongside childcare needs. Methods We conducted a cross-sectional analysis of patients who enrolled in the childcare facility from November 2020 to October 2022 to compare parameters of the Social Vulnerability Index (SVI) associated with the census tract extracted from electronic medical record (EMR) data among utilizers and non-utilizers of the facility. Overall SVI and segmentation into four themes of vulnerability (socioeconomic status, household characteristics, racial/ethnic minority status, and housing type/transportation) were compared across utilizers and utilizers. Number of 90th percentile indicators were also compared to assess extreme levels of vulnerability. A sample of utilizers additionally received a patient-reported social needs screening questionnaire administered at the childcare facility. Results Among 400 enrollees in the childcare facility, 70% utilized childcare services and 30% did not. Utilizers and non-utilizers were demographically similar, though utilizers were more likely to speak Spanish (34%) compared to non-utilizers (22%). Mean SVI was similar among utilizers and non-utilizers, but the mean number of 90th percentile indicators were higher for non-utilizers compared to utilizers (4.3 ± 2.7 vs 3.7 ± 2.7, p = 0.03), primarily driven by differences in the housing type/transportation theme (p = 0.01). Non-utilizers had a lower rate of healthcare utilization compared to utilizers (p = 0.02). Among utilizers who received patient-reported screening, 84% had one unmet social need identified, of whom 62% agreed for additional assistance. Among social work referrals, 44% were linked to social workers in their medical clinics, while 56% were supported by social work integrated in the childcare facility. Conclusions This analysis of SDOH approximated by SVI showed actionable differences, potentially transportation barriers, among patients with childcare needs who utilized a health system-integrated childcare facility and patients who did not utilize services. Furthermore, residual unmet social needs among patients who utilized the facility demonstrate the multifactorial nature of social risk factors experienced by patients with childcare needs and opportunities to address intersecting social needs within an integrated intervention. Intersecting social needs require holistic examination and multifaceted interventions

    Cost-effectiveness analysis of different combination therapies for the treatment of chronic lymphocytic leukaemia in IndiaResearch in context

    Summary: Background: Over the years, there has been introduction of newer drugs, like bendamustine and ibrutinib, for the management of chronic lymphocytic leukaemia (CLL). Though these drugs lead to better survival, they are also associated with higher cost. The existing evidence on cost effectiveness of these drugs is from high-income countries, which has limited generalisability for low-income and middle-income counties. Therefore, the present study was undertaken to assess the cost-effectiveness of three therapeutic regimens, chlorambucil plus prednisolone (CP), bendamustine plus rituximab (BR) and ibrutinib for CLL treatment in India. Methods: A Markov model was developed for estimating lifetime costs and consequences in a hypothetical cohort of 1000 CLL patients following treatment with different therapeutic regimens. The analysis was performed based on a limited societal perspective, 3% discount rate and lifetime horizon. The clinical effectiveness of each regime in the form of progression-free survival and occurrence of adverse events were assessed from various randomised controlled trials. A structured comprehensive review of literature was undertaken for the identification of relevant trials. The data on utility values and out of pocket expenditure was obtained from primary data collected from 242 CLL patients across six large cancer hospitals in India. Findings: As compared to the most affordable regimen comprising of CP as first-line followed by BR as second-line therapy, none of the other therapeutic regimens were cost-effective at one time per capita gross-domestic product of India. However, if the current price of either combination of BR and ibrutinib or even ibrutinib alone could be reduced by more than 80%, regimen comprising of BR as first-line therapy followed by second-line ibrutinib would become cost-effective. Interpretation: At the current market prices, regimen comprising of CP as first-line followed by BR as second-line therapy is the most cost-effective strategy for CLL treatment in India.
