Adverse drug reaction profile at psychiatry outpatient department of a tertiary care centre

Background: Monitoring adverse drug reactions (ADRs) helps in alerting physicians and developing strategies to prevent and minimize the risk of developing ADRs. Data regarding pattern of ADRs due to psychotropic medications is scanty. Hence, the study was planned to assess ADRs among psychiatry outpatients of a tertiary care hospital in Maharashtra.Methods: A prospective, observational study was conducted in psychiatry outpatient department of a tertiary care centre for 3 months. Cases were enrolled by active and passive surveillance after obtaining informed consent. Demographic details, adverse event details, history of medications were recorded. Pattern of ADRs was studied according to demographic parameters, drug class, organ system affected, causality (WHO - Uppsala Monitoring Centre Scale) and severity (modified Hartwig and Siegel Scale).Results: Out of total 1200 patients screened, 77 qualified the inclusion and exclusion criteria and 92 ADRs were reported; overall incidence rate of 6.41%. Maximum ADRs were reported in the age group of 31- 40 years. 63.63% subjects received more than 2 psychotropic drugs. Among 24 types of ADRs observed, tremor (13.04%) was the commonest, closely followed by somnolence. Antipsychotics (45.65%) were most frequently incriminated and central nervous system (46.73%) the most often affected. Trifluoperazine (11.96%) was the commonest drug, followed by olanzapine and haloperidol (10.53% each). Causality analysis yielded 66 ADRs as “probable” and on severity analysis 80.43% were mild.Conclusions: The study provides an insight into pattern of ADRs in psychiatry outpatients. It is prudent to communicate this to treating physicians as well as counsel patients (and caregivers). Initiatives and concerted efforts involving all stakeholders in healthcare can go a long way in decreasing drug-related morbidity and health costs

The ABCF3 Gene of Arabidopsis Is Functionally Linked with GCN1 but Not with GCN2 During Stress and Development

[EN] One of the main mechanisms regulating translation is the one based on the phosphorylation of the alpha subunit of the translation initiation factor 2 (eIF2 alpha) by the general control non-repressive 2 (GCN2) protein kinase. In yeast, this kinase binds to two scaffold proteins (GCN1 and GCN20), facilitating its activation on translating ribosomes. The homology of the three proteins exists in Arabidopsis. In this species, whereas the kinase is activated under several stress situations, the involvement of the scaffold proteins in those processes is controversial, and a new role for GCN1 in translation, independent of the phosphorylation of eIF2 alpha, has been proposed. Arabidopsis presents five genes with homology to GCN20 (ABCF1 to 5) in its genome. We show here that any of these five genes is needed for eIF2 alpha phosphorylation. Furthermore, plant phenotypes under abiotic stresses and chloroplast development suggest that ABCF3 is functionally linked with GCN1, but not with GCN2. Finally, gcn1 and abcf3 mutants share similar transcriptional reprogramming, affecting photosynthesis and stress responses. The common downregulation of regulators of the flagellin receptor FLS2 in both mutants suggest that the observed defect in pathogen-associated molecular pattern (PAMP)-induced stomatal closure of these two mutants could be mediated by these proteins.This work was funded by the Spanish Ministerio de Ciencia e Innovacion (MICINN), reference BFU2011-22526.

Study of survival of motor neuron (SMN) and neuronal apoptosis inhibitory protein (NAIP) gene deletions in SMA patients

In view of the paucity of deletion studies of survival of motor neuron (SMN) and neuronal apoptosis inhibitor protein (NAIP) genes in Indian SMA patients, this study has been undertaken to determine the status of SMN1, SMN2 and NAIP gene deletions in Indian SMA patients. Clinically and neurophysiologically diagnosed SMA patients were included in the study. A gene deletion study was carried out in 45 proximal SMA patients and 50 controls of the same ethnic group. Both SMN1 and NAIP genes showed homozygous absence in 76 % and 31 % respectively in proximal SMA patients. It is proposed that the lower deletion frequency of SMN1 gene in Indian patients may be due to mutations present in other genes or population variation, which need further study

Arabidopsis ILITHYIA protein is necessary for proper chloroplast biogenesis and root development independent of eIF2alpha phosphorylation

[EN] One of the main mechanisms blocking translation after stress situations is mediated by phosphorylation of the alpha-subunit of the eukaryotic initiation factor 2 (eIF2), performed in Arabidopsis by the protein kinase GCN2 which interacts and is activated by ILITHYIA(ILA). ILA is involved in plant immunity and its mutant lines present phenotypes not shared by the gcn2 mutants. The functional link between these two genes remains elusive in plants. In this study, we show that, although both ILA and GCN2 genes are necessary to mediate eIF2 alpha phosphorylation upon treatments with the aromatic amino acid biosynthesis inhibitor glyphosate, their mutants develop distinct root and chloroplast phenotypes. Electron microscopy experiments reveal that ila mutants, but not gcn2, are affected in chloroplast biogenesis, explaining the macroscopic phenotype previously observed for these mutants. ila3 mutants present a complex transcriptional reprogramming affecting defense responses, photosynthesis and protein folding, among others. Double mutant analyses suggest that ILA has a distinct function which is independent of GCN2 and eIF2 alpha phosphorylation. These results suggest that these two genes may have common but also distinct functions in Arabidopsis.Microarray experiments were done in the Genomics Facility of the IBMCP.

Of cattle, sand flies and men : a systematic review of risk factor analyses for South Asian visceral leishmaniasis and implications for elimination

Background: Studies performed over the past decade have identified fairly consistent epidemiological patterns of risk factors for visceral leishmaniasis (VL) in the Indian subcontinent. Methods and Principal Findings: To inform the current regional VL elimination effort and identify key gaps in knowledge, we performed a systematic review of the literature, with a special emphasis on data regarding the role of cattle because primary risk factor studies have yielded apparently contradictory results. Because humans form the sole infection reservoir, clustering of kala-azar cases is a prominent epidemiological feature, both at the household level and on a larger scale. Subclinical infection also tends to show clustering around kala-azar cases. Within villages, areas become saturated over a period of several years; kala-azar incidence then decreases while neighboring areas see increases. More recently, post kalaazar dermal leishmaniasis (PKDL) cases have followed kala-azar peaks. Mud walls, palpable dampness in houses, and peridomestic vegetation may increase infection risk through enhanced density and prolonged survival of the sand fly vector. Bed net use, sleeping on a cot and indoor residual spraying are generally associated with decreased risk. Poor micronutrient status increases the risk of progression to kala-azar. The presence of cattle is associated with increased risk in some studies and decreased risk in others, reflecting the complexity of the effect of bovines on sand fly abundance, aggregation, feeding behavior and leishmanial infection rates. Poverty is an overarching theme, interacting with individual risk factors on multiple levels. Conclusions: Carefully designed demonstration projects, taking into account the complex web of interconnected risk factors, are needed to provide direct proof of principle for elimination and to identify the most effective maintenance activities to prevent a rapid resurgence when interventions are scaled back. More effective, short-course treatment regimens for PKDL are urgently needed to enable the elimination initiative to succeed

Treatment of atypical central neurocytoma in a child with high dose chemotherapy and autologous stem cell rescue

The authors describe a 9 month old female with recurrent atypical central neurocytoma and leptomeningeal spread treated with high dose chemotherapy, autologous stem cell rescue, and adjuvant therapy. She had a complete response to therapy and was disease free at 4 years of age until a recurrence 6 months later. The use of intensive chemotherapy followed by autologous stem cell rescue for atypical neurocytoma may be considered as an adjunct to surgical therapy in young patients with atypical neurocytoma not amenable to radiation therapy

A comparative evaluation of endemic and non-endemic region of visceral leishmaniasis (Kala-azar) in India with ground survey and space technology

In visceral leishmaniasis, phlebotomine vectors are targets for control measures. Understanding the ecosystem of the vectors is a prerequisite for creating these control measures. This study endeavours to delineate the suitable locations of Phlebotomus argentipes with relation to environmental characteristics between endemic and non-endemic districts in India. A cross-sectional survey was conducted on 25 villages in each district. Environmental data were obtained through remote sensing images and vector density was measured using a CDC light trap. Simple linear regression analysis was used to measure the association between climatic parameters and vector density. Using factor analysis, the relationship between land cover classes and P. argentipes density among the villages in both districts was investigated. The results of the regression analysis indicated that indoor temperature and relative humidity are the best predictors for P. argentipes distribution. Factor analysis confirmed breeding preferences for P. argentipes by landscape element. Minimum Normalised Difference Vegetation Index, marshy land and orchard/settlement produced high loading in an endemic region, whereas water bodies and dense forest were preferred in non-endemic sites. Soil properties between the two districts were studied and indicated that soil pH and moisture content is higher in endemic sites compared to non-endemic sites. The present study should be utilised to make critical decisions for vector surveillance and controlling Kala-azar disease vectors

Risk factors of visceral leishmaniasis: a case control study in north-western Ethiopia

Background Visceral leishmaniasis (VL, also called “kala-azar”), is a life threatening neglected tropical infectious disease which mainly affects the poorest of the poor. VL is prevalent in Ethiopia particularly in the northwest of the country. Understanding the risk factors of VL infection helps in its prevention and control. The aim of the present study was to identify the factors associated with VL. Methods A case–control study was carried out during the period of January-July 2013 in northwest Ethiopia. Cases and controls were diagnosed using clinical presentation, the rk39 rapid diagnostic test and Direct Agglutination Test (DAT). A total of 283 (84.8% males versus 15.2% females) participants were interviewed. 90 cases and 193 controls were involved, matched by age, sex and geographical location with a ratio of 1:2 (case: controls). Univariate and backward multivariate conditional logistic regression were used to identify risk factors of VL. Results Elevated odds of VL was associated with goat ownership (OR = 6.4; 95%: confidence interval [Cl]: 1.5-28.4), living in houses with cracked wall (OR = 6.4; 95% Cl: 1.6-25.6), increased family size (OR = 1.3; 95% Cl: 1.0-1.8) and the number of days spent in the farm field (OR = 1.1; 95% Cl: 1.0-1.2). However, daily individual activities around the home and farm fields, mainly sleeping on a bed (OR = 0.2; 95%: Cl 0.03-0.9), sleeping outside the house under a bed net (OR = 0.1; 95% Cl: 0.02-0.36)] and smoking plant parts in the house during the night time (OR = 0.1; 95% Cl: 0.01-0.6) were associated with decreased odds of being VL case. Conclusion Our findings showed that use of bed net and smoke could be helpful for the prevention of VL in the area particularly among individuals who spend most of their time in the farm. VL control effort could be focused on improving housing conditions, such as sealing cracks and crevices inside and outside houses. Further research is warranted to elucidate the role of goats in the transmission of L. donovani, assess the impact of bed nets and the role of the traditional practice of smoking plants
