Rationality verses irrationality in fixed dose combinations: at a tertiary teaching hospital of rural Chhattisgarh, India
Background: Rational drug prescribing can be defined as appropriate drugs prescribed in the right dose, at correct time intervals and for a sufficient duration. Irrational drug use is a common problem in many countries of the world.Methods: A prospective observational study was conducted, total 300 patients attending various outpatient departments of tertiary health care rural hospital in Rajnandgaon district were interviewed and their prescriptions were analysed.Results: Total 350 drugs were prescribed 60 (17.14%) were prescribed by generic name and the rest 290 (82.86%) were prescribed by brand name. Only 18 (5.14%) drugs were not prescribed from hospital formulary. 264 (75.43%) drugs were dispensed from hospital pharmacy. On the basis of rationality score 53% prescriptions were rational, 30% semi rational and 17% irrational.Conclusions: In a rural hospital, where hospital formulary is based on WHO Essential medicine list, hundred percent utilization of hospital pharmacy service doctors and patients would ensure rational prescribing benefits of the patients coming from rural and uneducated background
A study of adverse drug reaction profile of tuberculosis patients attending DOTS center at Dr. Bhim Rao Ambedkar memorial hospital, Raipur, Chhattisgarh, India
Background: Tuberculosis is second leading cause of death in the world. The causative organism is Mycobacterium tuberculosis. The objective was to study the adverse reactions of the patients attending the DOTS center and to assess their causality and severity of reported ADRs.Methods: Present study was a prospective observational study carried at the DOTS center of Dr. Bhim Rao Ambedkar Memorial Hospital, Raipur, Chhattisgarh, India between August 2011 to July 2012 (One year). The patients were monitored for adverse drug reactions. The assessment of ADRs were based upon the WHO assessment scale, Naranjo scale, European A.B.O scale.Results: Total number of patients attending DOTS center was 816. The number of males (428) exceeded that of females (388). Majority of patients in this study belonged to 21-30 years (26.96%) next 31-40 years (25.24%) and 41-50 years (16.5%) of age group. Prevalence of ADRs were more in males (57%) than in females 32 (43%). Majority of ADRs reported were moderate 33 (35.22%) followed by 29 (46,77%) were mild, no severe ADRs reported. According to severity of ADRs seen were gastritis 28 (45%) followed by 10 (16% ) rashes , 10 (16,12%) of arthralgia, 3 (4.83%) of hepatitis, 6 (9.7%) of peripheral neuropathy, 2 (3%) onsets of ADRs after starting anti-tubercular drug were 12 (19.35%) in 0-1 week followed by 19 (30%) ADRs showed onset in 1-2 week and 2-3 week, 8 (13%) in 3-4 week 3 (5%) in 4-5 week and 1 (2%) in 5-6 week.Conclusions: The casual link between the ADRs and the suspected anti-tubercular drug by Naranjo scale definitely relationship was established between the anti-tubercular drug and ADRs in 7 (11.25%) patient while 22 (35.45%) probable and 33 (53.22%) ADRs were categorized as possible
Assessment of knowledge of pharmacotherapeutics amongst medical undergraduates of a tertiary care teaching hospital of Chhattisgarh, India: a questionnaire based study
Background: Knowledge of pharmacology forms the basis of rational pharmacotherapy practice. Teaching the medical students about systematic application of pharmacology in patients’ care forms an essential component.

Their suggestions regarding the change in teaching methodology was recorded.Conclusions: This study concludes that efforts are needed to develop a curriculum that encompasses important aspects of clinical pharmacology and therapeutics along with incorporation of the useful suggestions by the undergraduate students
Virological, immunological and pathological findings of transplacentally transmitted bluetongue virus serotype 1 in IFNAR1-blocked mice during early and mid gestation
© 2020, The Author(s). Transplacental transmission (TPT) of wild-type Indian BTV-1 had never been experimentally proved. This study was first time investigated TPT of Indian BTV-1 (isolated from aborted and stillborn goat fetal spleens). The sequential pathology, virological and immune cell kinetics (CD4+, CD8+ T-lymphocytes and NK cells in spleen and PBMCs), and apoptosis in IFNAR1-blocked pregnant mice during early (infected on 1 GD) and mid (infected on 8 GD) gestation have been studied. There was higher rate of TPT during mid stage (71.43%) than early (57.14%) stage. In early stage reduced implantation sites, early embryonic deaths, abortions, and necro-haemorrhagic lesions had observed. Mid stage, congenital defects and neurological lesions in foetuses like haemorrhages, diffuse cerebral edema, necrotizing encephalitis and decreased bone size (Alizarin red staining) were noticed. BTV-1 antigen was first time demonstrable in cells of mesometrium, decidua of embryos, placenta, uterus, ovary, and brain of foetuses by immunohistochemistry and quantified by real-time qRT-PCR. BTV-inoculated mice were seroconverted by 7 and 5 dpi, and reached peak levels by 15 and 9 dpi in early and mid gestation, respectively. CD4+ and CD8+ cells were significantly decreased (increased ratio) on 7 dpi but subsequently increased on 15 dpi in early gestation. In mid gestation, increased CD8+ cells (decreased ratio) were observed. Apoptotic cells in PBMCs and tissues increased during peak viral load. This first time TPT of wild-type Indian BTV-1 deserves to be reported for implementation of control strategies. This model will be very suitable for further research into mechanisms of TPT, overwintering, and vaccination strategies
Clinicopathological studies of Pasteurella multocida B:2 experimental infection in rabbits
The present study was carried out to study pathology and virulence of Pasteurella multocida B:2 isolated from natural outbreak of Pasteurella infection in rabbits. Healthy Pasteurella multocida B:2 free rabbits (12) were divided in control and challenged group. The challenged group rabbits were inoculated intra-nasally by spraying of 0.5 ml of inoculum in each nares, containing 1 × 105 CFU of Pasteurella multocida B:2 in BHI. The control group of rabbits was inoculated with 0.5 ml uncultured BHI broth in each nares in the same manner. Live animals were observed for atleast 14 days. The main clinical signs observed in infected rabbits comprised of conjunctivitis, nasal discharge, pyrexia, sneezing, dyspnoea and abdominal breathing. The pathomorphological changes in lungs comprised of acute fibrinous and/or fibrino suppurative bronchopneumonia/pleuropneumonia. Trachea showed acute inflammatory changes with multifocal erosion/ulcer and necrosis. Nasal cavity showed acute inflammation with accumulation of cellular debris in nasal meatus. Three infected rabbits showed meningitis characterized by congestion, infiltration of heterophils and minimal oedema. Pasteurella multocida B:2 was successfully detected in blood and tissues of infected rabbits by PCR. The organisms were also demonstrated in blood/impression smear from different organs
HIF-Independent Regulation of Thioredoxin Reductase 1 Contributes to the High Levels of Reactive Oxygen Species Induced by Hypoxia
Cellular adaptation to hypoxic conditions mainly involves transcriptional changes in which hypoxia inducible factors (HIFs) play a critical role. Under hypoxic conditions, HIF protein is stabilized due to inhibition of the activity of prolyl hydroxylases (EGLNs). Because the reaction carried out by these enzymes uses oxygen as a co-substrate it is generally accepted that the hypoxic inhibition of EGLNs is due to the reduction in oxygen levels. However, several studies have reported that hypoxic generation of mitochondrial reactive oxygen species (ROS) is required for HIF stabilization. Here, we show that hypoxia downregulates thioredoxin reductase 1 (TR1) mRNA and protein levels. This hypoxic TR1 regulation is HIF independent, as HIF stabilization by EGLNs inhibitors does not affect TR1 expression and HIF deficiency does not block TR1 hypoxic-regulation, and it has an effect on TR1 function, as hypoxic conditions also reduce TR1 activity. We found that, when cultured under hypoxic conditions, TR1 deficient cells showed a larger accumulation of ROS compared to control cells, whereas TR1 over-expression was able to block the hypoxic generation of ROS. Furthermore, the changes in ROS levels observed in TR1 deficient or TR1 over-expressing cells did not affect HIF stabilization or function. These results indicate that hypoxic TR1 down-regulation is important in maintaining high levels of ROS under hypoxic conditions and that HIF stabilization and activity do not require hypoxic generation of ROS
Report of the Task Force on Enhancing technology use in agriculture insurance
Pradhan Mantri Fasal Bima Yojana (PMFBY) is a flagship scheme of the Government of India to
provide insurance coverage and financial support to farmers in the event of failure of any of the
notified crops, unsown area and damage to harvest produce as a result of natural calamities, pests
and diseases to stabilise the income of farmers, and to encourage them to adopt modern agricultural
practices. The scheme is a considerable improvement over all previous insurance schemes in India
and is heavily subsidised by the state and central governments. The scheme aims to cover 50 percent
of the farming households within next 3 years.
During its implementation in the last one season, several challenges relating to enrolment, yield
estimation, loss assessment, and claim settlement were reported by farmers, insurance companies
as well as the state governments. It was also noted that several technological opportunities existed
for possibly leveraging support to the Indian crop insurance program for enhanced efficiency and
effectiveness. NITI Aayog of the Government of India, therefore, constituted a Task Force to deliberate
on this subject and identify such potential opportunities. This report summarises the recommendations
of the Task Force.
The Task Force constituted to address the issue of technology support to crop insurance comprised
the following 5 sub-groups: (1) Remote Sensing & Drones; (2) Decision Support Systems, Crop
Modelling & Integrated Approaches; (3) IT/ICT in Insurance; (4) Crop Cutting Experiments (CCEs); and
(5) Technologies for Livestock and Aquaculture Insurance. Each sub-group had several discussions
with experts in the respective areas, and submitted draft reports. More than 100 experts related to
professional research agencies, insurance industry, banks, and the government contributed to these
discussions. Technological options available in the country and abroad were considered by all groups.
The Task Force together with the sub-groups then deliberated on key issues and formulated its
recommendations as presented in this report. During the discussions it was realised that there were
many administrative and institutional issues that needed to be addressed in PMFBY. However, the
focus of the Task Force was on its main mandate, technology use in crop insurance. We hope these
recommendations would help the Indian crop insurance sector take full advantage of the technological
options suggested so as to increase its efficacy and effectiveness leading to reduced agrarian distress
in the country
Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ‘accidental cell death’ (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. ‘Regulated cell death’ (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to classify it into a few subtypes, which often (but not always) exhibit stereotyped morphologic features. Nonetheless, efficiently inhibiting the processes that are commonly thought to cause RCD, such as the activation of executioner caspases in the course of apoptosis, does not exert true cytoprotective effects in the mammalian system, but simply alters the kinetics of cellular demise as it shifts its morphologic and biochemical correlates. Conversely, bona fide cytoprotection can be achieved by inhibiting the transduction of lethal signals in the early phases of the process, when adaptive responses are still operational. Thus, the mechanisms that truly execute RCD may be less understood, less inhibitable and perhaps more homogeneous than previously thought. Here, the Nomenclature Committee on Cell Death formulates a set of recommendations to help scientists and researchers to discriminate between essential and accessory aspects of cell death
