Evaluation of effect of minocycline on rewarding potential and alcohol relapse in place preference model in mice

INTRODUCTION Medical management for alcohol abuse has limitations. Alcohol consumption activates N-methyl-d-aspartate receptors and release of nitric oxide which can be inhibited by minocycline as it readily crosses blood brain barrier and may have effect on alcohol consumption. Thus, study objective is to evaluate the effect of minocycline on rewarding property, extinction and the reinstatement phenomenon induced by alcohol in a model of conditioned place preference (CPP) in mice. METHODOLOGY To evaluate rewarding effects of alcohol, CPP procedure consisted of 4 parts, including adaptation (day 1), pre-conditioning test (day 2), conditionings with alcohol (days 3, 5, 7 and 9) or saline (days 4, 6, 8 and 10) and postconditioning test (day 11) conducted on 11 consecutive days. The groups included were saline treated group (alcohol control), naltrexone - 1mg/kg (positive control), and minocycline in the doses of 10, 30 and 50mg/kg. To evaluate the effect of minocycline on alcohol relapse, CPP procedure consisted 6 parts, the first 4 were the same as enumerated above followed by extinction (days 12-16) and reinstatement phase (day 17). RESULTS The time spent in alcohol paired compartment by different groups, revealed that minocycline and naltrexone significantly attenuated alcohol-induced place preference compared to alcohol control (p<0.05). Pretreatment with minocycline and naltrexone blocked reinstatement of extinguished CPP. CONCLUSION Minocycline may have a role in attenuating the rewarding property of alcohol and prevent alcohol relapse.

An Audit of Protocol Deviations Submitted to an Institutional Ethics Committee of a Tertiary Care Hospital

Protocol deviations (PDs) may jeopardize safety, rights, and welfare of subjects and data integrity. There is scarce literature and no guidelines for Institutional Ethics Committees (IECs) to process PD reports. The PD reports submitted to IECs from Jan 2011 to August 2014 were analyzed retrospectively. Types of studies reporting PDs, category and type of PDs, PD rate per participant, time of reporting PD since its occurrence and corrective actions stated by principal investigator (PI) for major deviations were noted. Out of 447 PDs from 73/1387 total studies received during study period, 402 were from 126 pharma studies. Investigator initiated studies and dissertations reported negligible PDs. Median number of PDs was 4 per protocol. Out of 447 PDs, 304 were related to study procedure, 87, 47 and 9 were from safety, informed consent document (ICD) and eligibility category respectively. The most common reason for PDs was incomplete ICD (22/47). Maximum study procedure related PDs were due to patient visiting outside window period (126/304). Thirty five of 87 PDs were due to missed safety assessment. The overall PD reporting rate per participant was 0.08. In 90% of reports, date of occurrence of PD was not specified. The median delay for reporting PDs after occurrence was 94 days. PDs classified as Major were 73% (323/447). The most common corrective actions stated by PI were participant counseling (85/323) and caution in future (70/323). The study findings emphasize the need for GCP training at regular interval of study team members. IEC have to be vigilant and visit sites frequently, take initiative and formulate guidelines regarding PD reporting.

Implementation of a module to promote competency in adverse drug reaction reporting in undergraduate medical students

Objectives: Underreporting and poor quality of adverse drug reaction (ADR) reports pose a challenge for the Pharmacovigilance Program of India. A module to impart knowledge and skills of ADR reporting to MBBS students was developed and evaluated. Materials and Methods: The module consisted of (a) e-mailing an ADR narrative and online filling of the “suspected ADR reporting form” (SARF) and (b) a week later, practical on ADR reporting was conducted followed by online filling of SARF postpractical at 1 and 6 months. SARF was an 18-item form with a total score of 36. The module was implemented in the year 2012–2013. Feedback from students and faculty was taken using 15-item prevalidated feedback questionnaires. The module was modified based on the feedback and implemented for the subsequent batch in the year 2013–2014. The evaluation consisted of recording the number of students responding and the scores achieved. Results: A total of 171 students in 2012–2013 batch and 179 in 2013–2014 batch participated. In the 2012–2013 batch, the number of students filling the SARF decreased from basal: 171; 1 month: 122; 6 months: 17. The average scores showed improvement from basal 16.2 (45%) to 26.4 (73%) at 1 month and to 27.3 (76%) at 6 months. For the 2013–2014 batch, the number (n = 179) remained constant throughout and the average score progressively increased from basal 10.5 (30%) to 27.8 (77%) at 1 month and 30.3 (84%) at 6 months. Conclusion: This module improved the accuracy of filling SARF by students and this subsequently will led to better ADR reporting. Hence, this module can be used to inculcate better ADR reporting practices in budding physicians.

Minocycline in Alcohol Withdrawal Induced Anxiety and Alcohol Relapse in Rats

INTRODUCTION Anxiety and negative sensations due to alcohol withdrawal are factors leading to alcohol relapse and addiction. Minocycline, an antibiotic, can decrease alcohol consumption in rats, however, its effects on alcohol withdrawal anxiety and relapse have not been studied. MATERIAL AND METHODS Part 1: Forced alcohol drinking in gradually increasing concentration was administered till day 22 in rats. Effect of drugs on anxiety was assessed using elevated plus maze (EPM) and two-chambered box apparatus, after removal of alcohol. Part 2: For relapse, an alcohol deprivation effect model was used, rats were continuously offered alcohol and water for 4 consecutive weeks in a two-bottle choice paradigm, followed by 2 weeks of alcohol deprivation. Effect of drugs on alcohol consumption during the first hour of alcohol reintroduction was assessed. Animals were sacrificed and whole brain Tumor Necrosis Factor (TNF) α was estimated. RESULTS Part 1: Anxiety at 3 hours was significantly lower following minocycline (20 mg/kg i.p.) or diazepam compared to vehicle control. Part 2: Acute administration of minocycline (5,10 and 20 mg/kg, i.p.) suppressed alcohol consumption significantly (p value<0.05) as compared to vehicle control. A significant decrease in whole brain TNF α was observed in animals treated with minocycline compared to untreated animals. CONCLUSION Minocycline attenuates alcohol withdrawal anxiety and disrupts alcohol relapse.

Payment for participation in clinical research: Review of proposals submitted to the ethics committees

Objective: In view of dearth of information in national and international guidelines on payment practices in research, the present study was done to find out payments for participation allowed by 3 Ethics committees (ECs) and reasons for payment. Method: This was a retrospective observational study which analysed research proposals reviewed by 2 institutional and 1 non-institutional ECs over a period of 2 years. The permission of ECs was obtained and confidentiality of data was maintained. Results: Of the 73 studies requiring payment, 89.04% were interventional and 10.96% observational. Reimbursement of travel expenses (60%) was the major reason for payment followed by inconvenience due to participation, loss of wages and time spent. The queries raised by EC in more than 50 % of studies were related to informing patients about the payment in the informed consent document. The investigators complied with the EC requirements regarding payment (15/21) and the remaining provided explanations. The median amount of payment in pharmaceutical sponsored studies was higher compared to investigator initiated studies. Higher payments were approved by ECs on case to case basis in a few studies. The ECs did not have any policy/ standard operating procedure for payment practices. Conclusion: The present study first of its kind in India, demonstrated that quantum of payment was not uniform for pharmaceutical sponsored and investigator initiated studies and payments were not considered for majority of observational studies. Travel reimbursement was the most common reason for payment. There is a need to develop guidelines for determining appropriate payment/incentives to participants for specific types of research related activities.

Five‐R framework for prescription communication skills learning

available for complexes I and II. At the end of the activity, each group was expected to explain all steps involved in ATP synthesis, including electron flux, maintenance of the proton gradient and how proton motive force is used to generate ATP. The effects of this active learning activity were evaluated using open-ended questionnaires answered by the students and comparisons between their performance on the question relative to this subject and questions encompassing other subjects in an open-book essay examination given that term. What lessons were learned? Over 80% of the students questioned strongly agreed that the method encourages meaningful and applicable understanding of basic and advanced bioenergetics concepts. Qualitative analysis of responses to the open-ended questionnaires indicated that students considered the method efficient, dynamic and engaging, and that it fostered better content understanding. The main weaknesses identified were unequal engagement by individual students in some groups and the significant disparity of previously acquired concepts among participants. Students who participated in the activity had, on average, better cognitive performance, as displayed by relative grades in the specific question related to this content in their examination, but did not have an overall increase in content assimilation in the formal evaluation. A statistically significant difference in the ability to understand oxidative phosphorylation was observed when compared with the 2015 class, which did not have access to this activity. Thus, the use of a board game fostered a positive educational environment, acting as an active teaching activity in which student engagement in the educational process enhanced learning.

Serious Adverse Events Reports: Analysis and Outcome of Review by an Institutional Ethics Committee of a Tertiary Care Hospital in Mumbai, India

The Indian regulations for clinical trials were amended in January 2013 regarding reporting time lines, relatedness, and compensation for Serious Adverse Events (SAEs). Our study assessed the extent of regulatory compliance in reporting SAEs to the Institutional Ethics Committee (IEC) over 4 years (January 2009-January 2013) before and 18 months after (February 2013-July 2014) the amended regulations. SAE reports were studied retrospectively for reporting time lines, relatedness, compensation, and IEC response before and after the law revision. Before 2013 had 89/160 (55.6%) SAEs reports submitted late while in the after period, only 2/11 reports were delayed (18%). In the before period, 26 SAE reports mentioned “relatedness” of which only 15 (57.6%) stated about compensation. After 2013, all the 9 non-death reports were complete. The IEC took median 17 days to respond before 2013, while after 2013 responded within 5 days. Thus, there was poor compliance in terms of SAE reporting time lines before the revision of the law.
