Effect of Global Warming on Indian Agriculture

Agriculture is the backbone of Indian economy which in turn relies on the monsoon season. The Intergovernmental Panel on Climate Change (IPCC) projected that the global mean surface temperature will likely rise and may result into uneven climatic changes such as irregular rainfall patterns, increased surface temperature and elevated CO2 content in the atmosphere. Research studies indicate that weathering parameters influence strongly (67%) compared to other factors like soil and nutrient management (33%) during the cropping season. Researchers have confirmed that crop yield falls by 3-5% for every 1°F increase in the temperature. Present study shows that the crop production is dependent on temperature and shows a funnel shape for all the seasons. At lower temperature both the properties are almost linearly correlated, whereas at higher temperatures, it increases but with large scattering. The findings may be helpful to study the effect of climate change on the crop production

A Low Concentration of Ethanol Impairs Learning but Not Motor and Sensory Behavior in Drosophila Larvae

Drosophila melanogaster has proven to be a useful model system for the genetic analysis of ethanol-associated behaviors. However, past studies have focused on the response of the adult fly to large, and often sedating, doses of ethanol. The pharmacological effects of low and moderate quantities of ethanol have remained understudied. In this study, we tested the acute effects of low doses of ethanol (∼7 mM internal concentration) on Drosophila larvae. While ethanol did not affect locomotion or the response to an odorant, we observed that ethanol impaired associative olfactory learning when the heat shock unconditioned stimulus (US) intensity was low but not when the heat shock US intensity was high. We determined that the reduction in learning at low US intensity was not a result of ethanol anesthesia since ethanol-treated larvae responded to the heat shock in the same manner as untreated animals. Instead, low doses of ethanol likely impair the neuronal plasticity that underlies olfactory associative learning. This impairment in learning was reversible indicating that exposure to low doses of ethanol does not leave any long lasting behavioral or physiological effects

Study of Monsoonal Features Using Regional Climate Model over Heterogeneous Monsoon Dominated Region

Global warming is an increase in average global temperature of the earth which lead to climate change. Heterogeneity in the earth-atmosphere system becomes difficult to capture at low resolution (1°x1°) by satellite. Such features may be captured by using high resolution model such as regional climate model (0.5°x 0.5°). This type of study is quite important for a monsoon dominated country like India where Indo-Gangetic Plains (IGP) faces highest heterogeneity due to its geographic location. Present study compares high resolution model features with satellite data over IGP for monsoon season during a normal rainfall year 2010 to understand the actual performance of model. Almost whole IGP simulates relative humidity (RH) with wide range (~50-100%), whereas satellite shows it with narrow range (~60-80%) during September, 2010. Thus model is able to pick the features which were missed by satellite. Hence further model simulation extends over India and adjoining oceanic regions which simulates data of southwest monsoon with high (~70-100%) RH, high (~0.4-0.7) cloud fraction (CF) and low (~80-200 W/m2) outgoing longwave radiation (OLR) over Arabian Sea during June, 2010. Such type of study can be useful to understand heterogeneity at regional scale with the help of high resolution model generated data

Coping in residual schizophrenia: Re-analysis of ways of Coping checklist

Background & objectives: Persons with schizophrenia use various coping strategies to adapt to distressing symptoms as well as to deal with daily stressors. Efforts have been made to explore alternative frameworks of coping using Ways of Coping Checklist (WCC) in persons with schizophrenia. This study aimed to re-analyze (factor analysis) the revised-WCC in Indian patients with residual schizophrenia. The secondary aim of the study was to evaluate the relationship of new framework of coping with psychopathology, disability and quality of life (QOL). Methods: Using a cross-sectional design, 103 patients with residual schizophrenia were assessed on WCC. A principal component analysis with varimax rotation was carried out to determine the factor structure of WCC. Results: Factor analysis yielded six factors which explained 51.6 per cent of the total variance and had acceptable-to-good internal consistency. Based on the type of items loaded, the six factors were named as follows: active and growth-oriented coping, accepting and fantasizing, reflective and confrontative coping, detachment, seeking social support and negative emotional coping. Patients most often used coping strategy of seeking social support, followed by 'accepting and fantasizing' and 'active and growth-oriented coping'. Correlation analysis showed that those who more often used 'active and growth-oriented coping' had less negative symptoms, lower level of disability and higher spiritual and overall QOL. Interpretation & conclusions: The factor structure of revised-WCC was different among patients with schizophrenia when compared with individuals without mental illness, living in the community. It was evident that use of certain adaptive coping strategies was associated with better QOL and lower level of psychopathology. Our findings provided a framework of coping in patients with residual schizophrenia and suggested that promotion of certain coping strategies might be useful in improving the QOL and reduction of psychopathology in patients with schizophrenia

Home-based telemental health services for Indian patients during the COVID-19 pandemic: A comparison with the pre-COVID phase

Background: Many developed countries have switched from conventional outpatient psychiatric services to tele mental health-based alternatives because of the COVID-19 pandemic. However, similar transitions might be difficult for countries like India because of a shortage of necessary resources. Therefore, the feasibility and acceptability of converting to a home-based tele mental health (HB-TMH) service during the pandemic were examined in an Indian hospital. Materials and Methods: A new and expanded version of an HB-TMH service was operated for all outpatients following the onset of the pandemic. Feasibility outcomes included operational viability, service utilization, service engagement, the need for additional in-person services, and the frequency of adverse events. Patients' and clinicians' satisfaction with different aspects of the service were evaluated using Likert-style questionnaires to ascertain acceptability. The outcomes during the prepandemic and pandemic phases were also compared. Results: The switch to HB-TMH services took 6 weeks during the pandemic. Patient numbers increased greatly following this transition. Attendance improved, the requirement for in-person services was low, and no serious adverse events were reported. However, patients' satisfaction levels were relatively low during the pandemic. Clinicians were more satisfied than the patients with HB-TMH treatment during the pandemic. Differences between them were less marked but still present before the pandemic. Pre- and postpandemic comparisons revealed that both patients and clinicians were more satisfied with all aspects of HB-TMH care before the pandemic than during it. Conclusions: Though conversion to HB-TMH services was feasible during the pandemic, such services need to be improved to enhance patient acceptability

Internal consistency & validity of Indian Disability Evaluation and Assessment Scale (IDEAS) in patients with schizophrenia

Background & objectives: The Indian Disability Evaluation and Assessment Scale (IDEAS) has been recommended for assessment and certification of disability by the Government of India (GOI). However, the psychometric properties of IDEAS as adopted by GOI remain understudied. Our aim, thus, was to study the internal consistency and validity of IDEAS in patients with schizophrenia. Methods: A total of 103 consenting patients with residual schizophrenia were assessed for disability, quality of life (QOL) and psychopathology using the IDEAS, WHO QOL-100 and Positive and Negative symptom scale (PANSS) respectively. Internal consistency was calculated using Cronbach′s alpha. For construct validity, relations between IDEAS, and psychopathology and QOL were studied. Results: The inter-item correlations for IDEAS were significant with a Cronbach′s alpha of 0.721. All item scores other than score on communication and understanding; total and global IDEAS scores correlated significantly with the positive, negative and general sub-scales, and total PANSS scores. Communication and understanding was significantly related to negative sub-scale score only. Total and global disability scores correlated negatively with all the domains of WHOQOL-100 (ρ<0.01). The individual IDEAS item scores correlated negatively with various WHOQOL-100 domains (ρ0< 0.01). Interpretation & conclusions: This study findings showed that the GOI-modified IDEAS had good internal consistency and construct validity as tested in patients with residual schizophrenia. Similar studies need to be done with other groups of patients

Vitamin D Deficiency in Children with Psychiatric Illness in a Tertiary Care Hospital in North India

Background: Vitamin D is increasingly recognized as important for brain health, apart from its role in endocrine and bone health. There is a growing recognition of worldwide “epidemic” of Vitamin D deficiency, and growing data from adult population illustrate the association between Vitamin D deficiency and psychiatric disorders. In children, its role is implicated in brain development, function, and psychiatric disorders. Aim: The aim of this study was to study the extent of Vitamin D deficiency in children and adolescents with psychiatric disorders. Methodology: Retrospective chart review of participants, who had attended the psychiatry outpatient department, was conducted to ascertain the extent of blood Vitamin D level requisition and its level. Results: Out of 836, 60 participants had received the requisition for blood Vitamin D level, and results were documented for 40 participants (males – 28; females – 12). No specific reason was cited for getting Vitamin D level done. The mean Vitamin D level was in the deficient range, i.e. 13.34 ng/ml with 80% of the sample having Vitamin D deficiency and 13% having insufficient Vitamin D level. More males had Vitamin D deficiency, however, the small number of females in the study limits the generalizability of the results. Among the diagnostic categories, neurodevelopmental disorders had lower mean Vitamin D level, with lowest Vitamin D for autism, i.e., 10.9 ng/ml. Conclusion: The cause-effect relationship between Vitamin D deficiency and childhood psychiatric disorders could not be derived from the study. However, it provides important initial data for the relationship between Vitamin D deficiency and childhood psychiatric disorders from India

Quetiapine: Relatively safe in overdose?

Compared to other antipsychotics quetiapine has been reported to be relatively safer in overdose. We report a case with paranoid schizophrenia who attempted suicide with 1400 mg of quetiapine and manifested drowsiness, supraventricular tachycardia (167/minute) and minimal ST depression in leads V1 to V6 on ECG; all other physiological parameters were normal. Gastric lavage, lorazepam 2mg i/v to control agitation, and 14-hour observation in emergency ended in she being sent home. Subsequently she was successfully managed with ECTs, and quetiapine 600mg and risperidone 6mg daily. This report tends to support the literature suggesting quetiapine as a relatively-safer-in-overdose antipsychotic, and preferable in medication-overdose-suicidal-risk cases
