A study on the usage of antimicrobial agents and adverse drug reaction of antimicrobial used in a tertiary care hospital in North East India

Background: Irrational use of antimicrobial agents (AMAs) has led to large scale development of drug resistance and adverse drug reactions (ADRs) which has become a growing world -wide concern. The study was conducted to analyze the prescribing pattern of AMAs and to evaluate the reported ADR of the AMAs prescribed.Methods: A prospective study was conducted by analyzing 900 case sheets receiving AMAs in a tertiary care hospital. The study plan included analysis of average number of AMA prescribed, morbidity profile of patients, types of AMAs used, drug prescribed by generic/brand name, injectable AMA preparations and appropriateness of indication of AMA used. Thirty reported cases of ADR were evaluated for their casualty by Narnajo’s scale and severity by Hartwigs scale.Results: Average number of drugs per prescription was 1.54. Most common morbidity was fever due to various causes. 86.2% of AMA used was antibiotics. About 72.0% of AMAs were prescribed by generic name. Percentage of injectable preparation was 85.0%. 65.0% of drugs were prescribed from Essential drug list (EDL). Most offending drug for ADR was fixed drug combination (FDC) 30.0%. Common organ system involved was skin (63.3%). Most of the ADR were possible (80.0%) and mild (76.6%) in nature.Conclusions: Average number of AMAs per prescription was1.54. Percentage of drug prescribed by generic name is encouraging. However use of injectable preparation was very high. Majority of AMAs prescribed were antibiotics which is also very high. Periodic prescription audit will provide feedback to the prescribers and help in reducing the prescribing error and ADR cases

TO EVALUATE THE HYPOGLYCEMIC EFFECT OF THE FRUIT PULP EXTRACT OF SPONDIAS PINNATA LINN. KURZ ON EXPERIMENTAL MODEL OF DIABETES MELLITUS

ABSTRACTObjective: To study the hypoglycemic effect of the fruit pulp extract of Spondias pinnata Linn. Kurz (EESP) on an experimental model of diabetes inalbino rats.Methods: A total of 30 healthy adult Swiss albino rats of either sex weighing between 150 g and 200 g were divided into five groups containing6 animals each. All the animals were kept under fasting for 24 hrs. Animals were given free access to rat - chew and water ad libitum. Alloxanmonohydrate of 120 mg/kg in normal saline was given intraperitoneally to induce diabetes. The blood glucose was checked before alloxanization andafter 24 hrs of alloxanization by withdrawing blood from the tip of the tail of each rat under anesthesia. The animals were considered diabetic whenthe blood glucose level has raised beyond 225 mg/dl. Group A, which was control group, has received alloxan and normal saline. The standard drug,glibenclamide 2.5 mg/kg, was given orally in Group B. Group C, Group D, and Group E animals have received EESP orally at the dose of 100 mg/kg,200 mg/kg, and 400 mg/kg, respectively. Blood samples were collected after treatment from rat tails vein at 0 hr, 2 hrs, 4 hrs, 8 hrs, and 14 days. Dataobtained were analyzed by one-way analysis of variance followed by Tukey's multiple comparison test.Results: EESP has shown hypoglycemic action in alloxan-induced diabetic rats. Hypoglycemic action of this ethanolic extract is comparable to that ofglibenclamide.Conclusion: This study demonstrates hypoglycemic action of EESP in the experimental model of diabetic rats.Keywords: Hypoglycemic, Spondias pinnata, Diabetes mellitus

Higher Blood Glucose within the Normal Range Is Associated with More Severe Strokes

Background. Higher fasting blood glucose (FBG) concentrations in the hyperglycemic range are associated with more severe strokes. Whether this association also extends into patients with FBG in the normoglycemic range is unclear. We studied the association of stroke severity and FBG in normoglycemic patients with ischemic stroke in a median of 7 days after stroke when the initial glycemic stress response has resolved. Method and Material. Included were 361 nondiabetic ischemic stroke patients with admission fasting blood glucose within 70–130 mg/dL admitted into an acute stroke rehabilitation unit in a median of 7 days after stroke. Data including neuroimaging, vital signs, cardiovascular risk factors, and admission functional independence measure (AFIM) were recorded prospectively. Results. FBG correlated with stroke severity in the normoglycemic 70–130 mg/dL range (FBG-AFIM correlation coefficient −0.17; P = 0.003). Odds ratio for more severe injury (below average AFIM score) was 2.02 for patients with FBG 110–130 mg/dL compared to FBG 70–90 mg/dL (95% confidence interval 1.10–3.73, P = 0.022). Each mg/dL increase in FBG was associated with an average decrease of 0.25 FIM points. In a multiple linear regression model, FBG was associated with more severe stroke (P = 0.002). Conclusion. One week after ischemic stroke, FBG within the normoglycemic range was associated with stroke severity

To study the pattern of suspected adverse drug reactions in patients coming to the department of dermatology in Gauhati Medical College and Hospital, Guwahati, Assam, India

Background: Cutaneous adverse drug reactions (ADRs) are the commonest ADRs (30-45%) and are responsible for about 2% of hospital admissions. This study was conducted to study the pattern of ADRs coming to the department of dermatology in a Tertiary Health Care Hospital. The objectives of the study were to assess the causality, severity, preventability, age distribution, sex distribution and the reactions occurring.Methods: Cross-sectional study. The suspected adverse drug reactions (ADRs) reported from the department of dermatology in the Spontaneous ADR reporting form was analysed in this study over a period of one year.Results: A total of 513 cases of reported ADRs were analysed. The highest number of ADRs was reported in the Age group 21-40 years with female preponderance. Erythematous maculopapular lesions were the most common ADR and maximum cases of ADRs were observed with steroids. Most cases were found to be probable (causality assessment), of mild severity and were probably preventable.Conclusions: The study showed that a number of drugs cause dermatological ADRs. These ADRs vary in their appearance, duration, causality, severity, and preventability

Butyrate, neuroepigenetics and the gut microbiome: Can a high fiber diet improve brain health?

As interest in the gut microbiome has grown in recent years, attention has turned to the impact of our diet on our brain. The benefits of a high fiber diet in the colon have been well documented in epidemiological studies, but its potential impact on the brain has largely been understudied. Here, we will review evidence that butyrate, a short-chain fatty acid (SCFA) produced by bacterial fermentation of fiber in the colon, can improve brain health. Butyrate has been extensively studied as a histone deacetylase (HDAC) inhibitor but also functions as a ligand for a subset of G protein-coupled receptors and as an energy metabolite. These diverse modes of action make it well suited for solving the wide array of imbalances frequently encountered in neurological disorders. In this review, we will integrate evidence from the disparate fields of gastroenterology and neuroscience to hypothesize that the metabolism of a high fiber diet in the gut can alter gene expression in the brain to prevent neurodegeneration and promote regeneration

A study on adverse drug reactions in a tertiary care hospital of Northeast India

Objective: Purpose of this study was to monitor adverse drug reactions reported from various departments of a tertiary care hospital in Northeast India. Reported adverse drug reactions were analysed for causality and severity assessment.Methods: This cross sectional study was conducted in a tertiary care hospital at Guwahati, Northeast India, for 7 months. Patients of all age and either sex were included. Adverse drug reactions were reported by the physicians of this hospital and their causality and severity assessments were performed as per Naranjo’s and Hartwig’s assessment criteria respectively. Descriptive statistics were used for data analysis.Results: Total 255 adverse drug reactions were reported from various departments of this tertiary care hospital. Most of the adverse drug reactions were observed in the age group of 21–30 year. Acne (46) was commonly reported reaction. Topical steroids, betamethasone sodium phosphate and clobetasol were reported to induce maximum number of reactions (59). Skin (227, 66.9%) was commonly affected organ system. Most of the adverse drug reactions were possible (240, 94.1%) and mild (222, 87%) in nature.Conclusions: The topical steroid (betamethasone sodium phosphate) was reported to induce adverse drug reactions in majority of the patients. The commonly reported reaction was acne.Keywords: ADRs; Northeast; Naranjo; Hartwig; Pharmacovigilanc

Dissociative Autoionization in (1+2)-photon Above Threshold Excitation of H2 Molecules

We have theoretically studied the effect of dissociative autoionization on the photoelectron energy spectrum in (1+2)-photon above threshold ionization(ATI) of H2 molecules. We have considered excitation from the ground state X-singlet-Sigma-g+(v=0,j) to the doubly excited autoionizing states of singlet-Sigma-u+ and singlet-Pi-u+ symmetry, via the intermediate resonant B-singlet-Sigma-u+(v=5,j) states. We have shown that the photoelectron energy spectrum is oscillatory in nature and shows three distinct peaks above the photoelectron energy 0.7 eV. This feature has been observed in a recent experiment by Rottke et al, J. Phys. B, Vol. 30, p-4049 (1997).Comment: 11 pages and 4 figure
