    A detrimental interaction between smoking and alcohol consumption with respect serum γ-glutamyltransferase (γ-GT) has recently been described. The underlying mechanisms remain unknown. The present work aimed to provide further insights by examining similar interactions pertaining to aspartate and alanine transaminase (AST, ALT), routine liver markers less prone to enzyme induction.<0.0001). The interactions all were in the same directions as for γ-GT, i.e. synergistic with alcohol and opposite with BMI.The patterns of interaction between smoking and alcohol consumption or BMI with respect to AST and ALT resembled those observed for γ-GT. This renders enzyme induction a less probable mechanism for these associations, whereas it might implicate exacerbated hepatocellular vulnerability and injury

    Can antibiotic prescriptions in respiratory tract infections be improved? A cluster-randomized educational intervention in general practice – The Prescription Peer Academic Detailing (Rx-PAD) Study [NCT00272155]

    BACKGROUND: More than half of all antibiotic prescriptions in general practice are issued for respiratory tract infections (RTIs), despite convincing evidence that many of these infections are caused by viruses. Frequent misuse of antimicrobial agents is of great global health concern, as we face an emerging worldwide threat of bacterial antibiotic resistance. There is an increasing need to identify determinants and patterns of antibiotic prescribing, in order to identify where clinical practice can be improved. METHODS/DESIGN: Approximately 80 peer continuing medical education (CME) groups in southern Norway will be recruited to a cluster randomized trial. Participating groups will be randomized either to an intervention- or a control group. A multifaceted intervention has been tailored, where key components are educational outreach visits to the CME-groups, work-shops, audit and feedback. Prescription Peer Academic Detailers (Rx-PADs), who are trained GPs, will conduct the educational outreach visits. During these visits, evidence-based recommendations of antibiotic prescriptions for RTIs will be presented and software will be handed out for installation in participants PCs, enabling collection of prescription data. These data will subsequently be linked to corresponding data from the Norwegian Prescription Database (NorPD). Individual feedback reports will be sent all participating GPs during and one year after the intervention. Main outcomes are baseline proportion of inappropriate antibiotic prescriptions for RTIs and change in prescription patterns compared to baseline one year after the initiation of the tailored pedagogic intervention. DISCUSSION: Improvement of prescription patterns in medical practice is a challenging task. A thorough evaluation of guidelines for antibiotic treatment in RTIs may impose important benefits, whereas inappropriate prescribing entails substantial costs, as well as undesirable consequences like development of antibiotic resistance. Our hypothesis is that an educational intervention program will be effective in improving prescription patterns by reducing the total number of antibiotic prescriptions, as well as reducing the amount of broad-spectrum antibiotics, with special emphasis on macrolides

    Objective: To examine the drug prescription pattern in Danish women from 12 weeks prior to conception until 12 weeks post-partum. Method: A drug utilization study based on The North Jutland Prescription Database. The Danish pharmacies use a computerized accounting system for all subsidized drugs and this was linked to the Danish Medical Birth Registry concerning prescription patterns for all women who had given birth in the county of North Jutland from 1991 to 1996. Results. The analysis included 16 001 primiparous women, who had redeemed 34 834 prescriptions prior to, during and after pregnancy. During pregnancy 44.2% of the women received prescriptions for at least one drug, Users received 2.6 prescriptions on average during pregnancy; 5% of the users redeemed 24.2% of all prescriptions. The proportion of women who redeemed prescriptions for more than three different drugs was 2.7%. The majority of prescriptions were for antibiotics (28.7%), gynaecological drugs (13.3%) and anti-asthma drugs (7.6%). The post-partum prescription proportion was 34.0% and the majority of the prescriptions during this period were for penicillins (20.1%), opthalmologicals (15.5%) and corticosteroids for dermatological use (5.7%). Conclusion: A high proportion of the women received drugs during pregnancy. The pattern of drug use within the Anatomical Therapeutical Chemical (ATC) groups changed, i.e. the amount of broad spectrum antibiotics decreased and the proportion of prescriptions for local use increased. A small proportion of women redeemed prescriptions for more than three different drugs during pregnancy
