Antibiotic Prescribing for Acute Respiratory Tract Infections 12 Months After Communication and CRP Training: A Randomized Trial.

PURPOSE: C-reactive-protein (CRP) is useful for diagnosis of lower respiratory tract infections (RTIs). A large international trial documented that Internet-based training in CRP point-of-care testing, in enhanced communication skills, or both reduced antibiotic prescribing at 3 months, with risk ratios (RRs) of 0.68, 0.53, 0.38, respectively. We report the longer-term impact in this trial. METHODS: A total of 246 general practices in 6 countries were cluster-randomized to usual care, Internet-based training on CRP point-of-care testing, Internet-based training on enhanced communication skills and interactive booklet, or both interventions combined. The main outcome was antibiotic prescribing for RTIs after 12 months. RESULTS: Of 228 practices providing 3-month data, 74% provided 12-month data, with no demonstrable attrition bias. Between 3 months and 12 months, prescribing for RTIs decreased with usual care (from 58% to 51%), but increased with CRP training (from 35% to 43%) and with both interventions combined (from 32% to 45%); at 12 months, the adjusted RRs compared with usual care were 0.75 (95% CI, 0.51-1.00) and 0.70 (95% CI, 0.49-0.93), respectively. Between 3 months and 12 months, the reduction in prescribing with communication training was maintained (41% and 40%, with an RR at 12 months of 0.70 [95% CI, 0.49-0.94]). Although materials were provided for free, clinicians seldom used booklets and rarely used CRP point-of-care testing. Communication training, but not CRP training, remained efficacious for reducing prescribing for lower RTIs (RR = 0.7195% CI, 0.45-0.99, and RR = 0.76; 95% CI, 0.47-1.06, respectively), whereas both remained efficacious for reducing prescribing for upper RTIs (RR = 0.60; 95% CI, 0.37-0.94, and RR = 0.58; 95% CI, 0.36-0.92, respectively). CONCLUSIONS: Internet-based training in enhanced communication skills remains effective in the longer term for reducing antibiotic prescribing. The early improvement seen with CRP training wanes, and this training becomes ineffective for lower RTIs, the only current indication for using CRP testing.

Alcohol Drinking Pattern Is Associated with Demographic Features of Primary Health Care Patients in Poland: A Cross-Sectional Study.

BACKGROUND The Optimizing Delivery of Health Care Interventions (ODHIN) project focused on the implementation of screening and brief intervention for hazardous and harmful alcohol consumption in primary health care. The aim of the present study was to investigate whether alcohol drinking pattern is associated with demographic features of primary health care patients in Poland and if it is possible to identify groups at highest risk for hazardous and harmful drinking. MATERIAL AND METHODS The study enrolled 8805 adult (mean age 54.98±16.94, M/F - 3581/5224) patients reporting to 30 general practitioners working in 10 primary health care units located in urban and partially rural areas in Poland. The shortened, 3-item version of the Alcohol Use Disorders Identification Test (AUDIT-C) was the screening tool used. RESULTS Place of residence was significantly associated with higher odds of hazardous and harmful drinking diagnosis, referred to as AUDIT-C (+). Age and sex were significantly associated with AUDIT-C (+) and suspicion of alcohol dependence, referred to as AUDIT-C ³8 scores. Logistic regression revealed that males had 5-fold higher odds for hazardous and harmful drinking diagnosis and almost 28-fold higher odds for suspected alcohol dependence compared to females. CONCLUSIONS Demographic features are associated with drinking pattern of primary health patients in Poland. Young males and those inhabiting rural areas are at highest risk of being hazardous or harmful drinkers and of being alcohol dependent. There is a growing need for development of national guidelines to address the prevention of alcohol-related health problems by general practitioners.

Delivery of Brief Interventions for Heavy Drinking in Primary Care: Outcomes of the ODHIN 5-Country Cluster Randomized Trial.

PURPOSE: We aimed to test whether 3 strategies-training and support, financial reimbursement, and an option to direct screen-positive patients to an Internet-based method of giving brief advice-have a longer-term effect on primary care clinicians' delivery of screening and advice to heavy drinkers operationalized with the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) tool. METHODS: We undertook a cluster randomized factorial trial with a 12-week implementation period in 120 primary health care units throughout Catalonia, England, Netherlands, Poland, and Sweden. Units were randomized to 8 groups: care as usual (control); training and support alone; financial reimbursement alone; electronic brief advice alone; paired combinations of these conditions; and all 3 combined. The primary outcome was the proportion of consulting adult patients (aged 18 years and older) receiving intervention-screening and, if screen-positive, advice-at 9 months. RESULTS: Based on the factorial design, the ratio of the log of the proportion of patients given intervention at the 9-month follow-up was 1.39 (95% CI, 1.03-1.88) in units that received training and support as compared with units that did not. Neither financial reimbursement nor directing screen-positive patients to electronic brief advice led to a higher proportion of patients receiving intervention. CONCLUSIONS: Training and support of primary health care units has a lasting, albeit small, impact on the proportion of adult patients given an alcohol intervention at 9 months.

Telomere Length Assessment for Prediction of Organ Transplantation Outcome. Future or Failure: A Review of the Literature.

Telomeres are located at each end of eukaryotic chromosomes. Their functional role is genomic stability maintenance. The protective role of telomeres depends on various factors, including number of nucleotides repeats, telomere-binding proteins, and telomerase activity. Organ transplantation is the preferred replacement therapy in the case of chronic kidney disease and the only possibility of sustaining recipients' life in the case of advanced liver failure. While the prevalence of acute rejection is constantly decreasing, prevention of transplanted organ long-term function loss is still challenging. It has been demonstrated that post-transplant stressors accelerate aging of the allografts manifested through telomere shortening. The aim of this paper was to evaluate the importance of telomere length assessment for prediction of organ transplantation outcome. Literature review included the 10 most important studies regarding linkage between allograft function and telomere erosion, including 2 of our own reports. Telomere length assessment is useful to predict organ transplantation outcome. The importance of telomere length as a prediction marker depends on the analyzed material. To obtain reliable results, both graft cells (donor material) and lymphocytes (recipient material) should be examined. In the case of kidney transplantation, assessment of telomere length in the early post-transplant period allows prediction of the long-term function of the transplanted organ. To increase the accuracy of transplantation outcome prediction, telomere length assessment should be combined with evaluation of other aging biomarkers, like CDKN2A (p16). Large-scale clinical studies regarding telomere length measurement, including genome wide association analysis introducing relevant genetic factors, are needed for the future.

Joint Assessment of Donor and Recipient hTERT Gene Polymorphism Provides Additional Information for Early Kidney Transplantation Outcomes.

BACKGROUND There are several genes and genetic loci affecting telomere length, including hTERT gene and BICD1 gene as well as polymorphisms within chromosome 18. It has been demonstrated that the age of the donor is a negative factor associated with long-term kidney allograft function, and that post-transplant complications accelerate transplanted organ aging, thus contributing to estimated glomerular filtration rate (eGFR) decreases. The aim of this study was a joint assessment of donors' and recipients' hTERT and BICD1 genes as well as chromosome 18 polymorphisms with regard to early kidney transplantation outcomes. MATERIAL AND METHODS The study enrolled 74 pairs of Polish Caucasian kidney allograft cadaveric donors (60% male, mean age 45.99±14.62) and recipients (50.0% male, mean age 48.89±13.50). The transplantation procedure (Tx) was performed between 2001 and 2012. All samples were genotyped in duplicate using Real-Time PCR. RESULTS This study showed that rs2735940 hTERT CX-TT donor-recipient genotype pair was associated with almost five times higher odds (OR=4.82; 95% CI: 1.32-18; p=0.016) of delayed graft function (DGF), and that rs2735940 hTERT, rs2630578 BICD1, and rs7235755 chromosome 18 polymorphisms combined pairs were not associated with acute rejection (AR). CONCLUSIONS In conclusion, both the donor's and the recipient's rs2735940 hTERT gene polymorphism was associated with early graft function after transplantation. The odds of DGF were almost five times higher for a combination of CX (CT or CC) donor genotype and TT recipient genotype. Joint assessment of donor-recipient genotype pairs provides more information for prediction of early kidney transplantation outcomes.

Professional's Attitudes Do Not Influence Screening and Brief Interventions Rates for Hazardous and Harmful Drinkers: Results from ODHIN Study.

AIMS: To determine the relation between existing levels of alcohol screening and brief intervention rates in five European jurisdictions and role security and therapeutic commitment by the participating primary healthcare professionals. METHODS: Health care professionals consisting of, 409 GPs, 282 nurses and 55 other staff including psychologists, social workers and nurse aids from 120 primary health care centres participated in a cross-sectional 4-week survey. The participants registered all screening and brief intervention activities as part of their normal routine. The participants also completed the Shortened Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ), which measure role security and therapeutic commitment. RESULTS: The only significant but small relationship was found between role security and screening rate in a multilevel logistic regression analysis adjusted for occupation of the provider, number of eligible patients and the random effects of jurisdictions and primary health care units (PHCU). No significant relationship was found between role security and brief intervention rate nor between therapeutic commitment and screening rate/brief intervention rate. The proportion of patients screened varied across jurisdictions between 2 and 10%. CONCLUSION: The findings show that the studied factors (role security and therapeutic commitment) are not of great importance for alcohol screening and BI rates. Given the fact that screening and brief intervention implementation rate has not changed much in the last decade in spite of increased policy emphasis, training initiatives and more research being published, this raises a question about what else is needed to enhance implementation.

Effects of internet-based training on antibiotic prescribing rates for acute respiratory-tract infections: a multinational, cluster, randomised, factorial, controlled trial.

BACKGROUND: High-volume prescribing of antibiotics in primary care is a major driver of antibiotic resistance. Education of physicians and patients can lower prescribing levels, but it frequently relies on highly trained staff. We assessed whether internet-based training methods could alter prescribing practices in multiple health-care systems. METHODS: After a baseline audit in October to December, 2010, primary-care practices in six European countries were cluster randomised to usual care, training in the use of a C-reactive protein (CRP) test at point of care, in enhanced communication skills, or in both CRP and enhanced communication. Patients were recruited from February to May, 2011. This trial is registered, number ISRCTN99871214. RESULTS: The baseline audit, done in 259 practices, provided data for 6771 patients with lower-respiratory-tract infections (3742 [55·3%]) and upper-respiratory-tract infections (1416 [20·9%]), of whom 5355 (79·1%) were prescribed antibiotics. After randomisation, 246 practices were included and 4264 patients were recruited. The antibiotic prescribing rate was lower with CRP training than without (33% vs 48%, adjusted risk ratio 0·54, 95% CI 0·42-0·69) and with enhanced-communication training than without (36% vs 45%, 0·69, 0·54-0·87). The combined intervention was associated with the greatest reduction in prescribing rate (CRP risk ratio 0·53, 95% CI 0·36-0·74, p<0·0001; enhanced communication 0·68, 0·50-0·89, p=0·003; combined 0·38, 0·25-0·55, p<0·0001). INTERPRETATION: Internet training achieved important reductions in antibiotic prescribing for respiratory-tract infections across language and cultural boundaries.

Management of respiratory tract infections in primary care in Poland--results of the happy audit 2 project.

OBJECTIVE: The Polish results of the international Happy Audit 2 project are reported which objective was to present therapeutic decisions made by general practitioners (especially antibiotics prescribed) and diagnostic methods applied to patients with respiratory tract infections (RTI). MATERIAL AND METHODS: [corrected] Following each visit of patient with respiratory tract infection, general practitioners participating in the study completed the questionnaire. The questionnaire included patient's data (age, gender), the duration of disease, clinical symptoms, diagnosis, prescribed antibiotics, additional testing as well as the influence of various factors on therapeutic decision. RESULTS: Having considered the results of HappyAudit in Poland, a total of 5,137 office visits of patients reporting symptoms of RTIs were analyzed. The average duration of symptoms before visiting GP was 4.8 days (compared to average 4.4 in other countries). Worth noting is that additional testing in diagnosis of RTIs was performed less frequently in Poland: rapid streptococcal test was conducted in 0.4% of cases (European average: 4.45%), CRP--in 2.2% of patients (average from other countries: 14.2%) and chest X-ray in 2.3% of cases compared to 14% in other project's participants. In Poland, the most frequently applied antibiotic was amoxicillin, which was used in 28.9% of cases ended with antibiotic prescribing (amoxicillin/pivampicillin were also predominant in other countries, excluding Sweden). In Poland, macrolides (22.4% of all prescriptions for antibiotic) and cephalosporins (12.1%) were frequently used. The results indicate that narrow-spectrum antibiotics are prescribed in Poland less frequently, with the example being penicillin V which was prescribed in 6.7% of patients with RTIs who were given antibiotic. CONCLUSIONS: Comparing the results of Happy Audit 2 in Poland and other project's participants, the major differences consist in rare use of phenoxymethylpenicillin in favour of amoxicillin and macrolides as well as infrequent use of additional testing in diagnosis of RTIs in Poland.

Association between low-dose folic acid supplementation and blood lipids concentrations in male and female subjects with atherosclerosis risk factors.

BACKGROUND: Folic acid (FA) is one of the B complex vitamins. It is thought that FA deficiency promotes atherosclerosis formation in arterial endothelium. FA, acting through reducing homocysteine (Hcy) levels, may contribute to decreased cholesterol (Ch) synthesis. The aim of this study was to analyze the association of low-dose folic acid supplementation with blood lipids concentrations in subjects with atherosclerosis risk factors. MATERIAL/METHODS: The study enrolled 124 Caucasian individuals (60 M, ages 20-39; and 64 F, ages 19-39) with atherosclerosis risk factors (family history of premature ischemic stroke, arterial hypertension, dyslipidemia, overweight and obesity, cigarette smoking, and low level of physical activity). The participants were asked to take FA at a low dose of 0.4 mg/24 h for 12 weeks. RESULTS: FA levels increased in females (6.3 vs. 12.5 ng/dL; p=0.001) and males (6.4 vs. 11.4 ng/dL; p=0.001) and Hcy levels decreased (10.6 vs. 8.3 µmol/L; p=0.001 and 11.5 vs. 9.3; p=0.001, respectively). A significant reduction in mean concentration of total cholesterol in females (203.4 vs. 193.1 mg/dL; p=0.001) and in males (209.5 vs. 201.9; p=0.002) was observed. The low-density lipoprotein cholesterol (LDL-C) levels decreased in females and in males (107.4 vs. 99.9 mg/dL; p=0.001 and 121.5 vs. 115.1; p=0.002, respectively). The apoAI concentrations increased in smoking women and in men with BMI≥25 kg/m2 (p=0.032 and p=0.024, respectively). CONCLUSIONS: Low-dose FA supplementation has a beneficial effect on blood lipids through decreasing concentrations of total cholesterol and LDL-C and increasing concentrations of apoAI.

Beneficial effects of SARS-CoV-2 vaccination resulting from the COVID-19 pandemic with regard to the uptake of influenza virus, pneumococcal, and herpes zoster adult vaccination - a narrative literature review.

INTRODUCTION AND OBJECTIVE: Analysis of factors influencing COVID-19 vaccination coverage in various countries raised the question whether the recent pandemic affected the vaccination rates of other pathogens in adults. Therefore, the aim of this review article was to analyse the literature to find potentially beneficial effects of the introduction of the large-scale vaccinations resulting from the COVID-19 pandemic, with regard to the influenza virus, pneumococcal and herpes zoster adult vaccinations, in order to identify factors and strategies to increase the uptake of these vaccines. REVIEW METHODS: The review of the literature was based on scientific articles indexed in the PubMed Database published between 2022-2023, during the COVID-19 pandemic. Data search was performed from 24-30 July 2023. BRIEF DESCRIPTION OF THE STATE OF KNOWLEDGE: It was found that the COVID-19 pandemic has had a beneficial effect on the acceptance and coverage of influenza and pneumococcal vaccination in the vulnerable elderly populations, and among healthcare workers in the case of influenza. Furthermore, the COVID-19 outbreak affected the designs of vaccine clinical trials, resulting in a lower frequency of age-related exclusion criteria, broadening the group of vaccine recipients. SUMMARY: Acceptance of COVID-19 vaccination increased willingness to accept other vaccines. The attitude to vaccination is a personal decision-making process based on previous experience and interpersonal interactions, greatly affected by information and recommendation from medical professionals. The COVID-19 pandemic vaccination implementation opened new opportunities to develop prevention efforts and build vaccination strategies in middle-income countries.

Attitudes toward preventive services and lifestyle: the views of primary care patients in Europe. the EUROPREVIEW patient study.

BACKGROUND: For preventive interventions in general practice to succeed, patients' points of view must be taken into account in addition to those of GPs. OBJECTIVE: To explore patients' views and beliefs about the importance of lifestyle and preventive interventions, to assess their readiness to make changes to their lifestyle and their willingness to receive support from GPs. METHODS: Cross-sectional survey conducted by EUROPREV in primary care practices in 22 European countries. Patients were consecutively selected and interviewed from September 2008 to September 2009. RESULTS: Seven thousand nine hundred and forty-seven participants, 52.2% females. Only 30.5% of risky drinkers think they need to change, as opposed to 64% of smokers, 73.5% of patients with unhealthy eating habits and 73% with lack of physical activity. Risky drinkers reported that GPs initiated a discussion on alcohol consumption less often (42%) than on smoking (63%), eating habits (59%) or physical activity (55%). Seventy-five per cent, 66% and 63% of patients without hypertension, diabetes or hypercholesterolaemia, respectively, think blood pressure, blood sugar and serum cholesterol should be checked yearly. Women (80%) think they should be screened with the cervical smear test and 72.8% of women aged 30-49 years with mammography, yearly or every 2 years. CONCLUSIONS: A high proportion of patients attending primary care with unhealthy lifestyles (especially risky drinkers) do not perceive the need to change their habits, and about half the patients reported not having had any discussion on healthy lifestyles with their GPs. Patients overestimate their need to be screened for cardiovascular risk factors and for cancer.

Is there an effect of folic acid supplementation on the coagulation factors and C-reactive protein concentrations in subjects with atherosclerosis risk factors?

INTRODUCTION: Folic acid (FA) may delay the formation of atherosclerotic lesions. Increased plasma levels of von Willebrand factor (VWF) are observed in cardiovascular disease, which leads to higher risk of thrombosis. Fibrinogen (Fb) is a well-documented risk factor of cardiovascular disease. The aim of this study was to analyze the effect of FA supplementation on the Fb, VWF and C-reactive protein (CRP) plasma concentrations in subjects with atherosclerosis risk factors. MATERIAL/METHODS: The study enrolled 124 Caucasian individuals (60 M, 64 F) with atherosclerosis risk factors--family history of premature ischaemic stroke, arterial hypertension, dyslipidaemia, overweight and obesity, cigarette smoking and low physical activity. The participants were asked to take FA in the low dose of 0.4 mg/24 h for three months. RESULTS: After FA supplementation a significant reduction of the VWF concentrations in females (76.6 vs 72.3%; p=0.028) and in males (75.5 vs 66.9%; p=0.001) was observed. Among women and men with dyslipidaemia concentrations of VWF decreased after FA supplementation (76.8% vs 69.6%; p=0.003 and 76.7% vs 67.8%; p=0.001 respectively). Among females and males with BMI ≥25 kg/m² concentrations of VWF decreased only in men (77.6% vs 66.5%; p=0.001). In female and male smokers supplementation of FA decreased VWF concentrations (82.5% vs 74.4%; p=0.012 and 76.6% vs 69.5%; p=0.036 respectively). DISCUSSION: The results of our study suggest that there is an effect of FA supplementation on VWF concentrations in subjects with atherosclerosis risk factors.

Fear of Illness and Convenient Access to Vaccines Appear to Be the Missing Keys to Successful Vaccination Campaigns: Analysis of the Factors Influencing the Decisions of Hospital Staff in Poland concerning Vaccination against Influenza and COVID-19.

The COVID-19 pandemic has lasted for two years as of 2022, and it is common knowledge that vaccines are an essential tool to mitigate the health, economic, and social fallout. Unfortunately, vaccine hesitancy is still a serious global problem, both in the general population and among healthcare workers. The authors used an original questionnaire to conduct an anonymous survey study in the University Clinical Hospital in Wroclaw, Poland, in April and May of 2021 after acquiring consent from the Medical University of Wroclaw, Poland Bioethical Committee. The study results demonstrate that, to a significant extent, the decisions concerning vaccinations are based on factors that are difficult to change with rational argumentation, including people's personal opinions or beliefs concerning vaccinations and their earlier experiences with vaccinations. The study results suggest that the impregnating effect of one's own opinions, beliefs, and experiences can be surmounted if vaccines are dispensed free and conveniently while the pathogen is irrationally and emotionally perceived as untamed and possibly severe and life threatening. It makes a significant difference as in such cases that the percentage of participants whose decisions concerning vaccination are influenced by the risks to life or health of one's own or others rises by about 27 and 36 percent points, respectively. Therefore, in order to succeed, campaigns for vaccinations need to include strong subjective and emotional communication, appealing to negative emotions and exploiting the public's fear of the unknown while stressing tangible and personal threats possibly resulting from acquiring a vaccine-preventable infectious disease.

Does the progeny of premature ischemic stroke sufferers need intensive interest of physicians oriented toward primary prevention? A pilot study.

BACKGROUND: Few studies focus on the progeny of stroke patients with respect to the occurrence of other potential risk factors. METHODS: The study group covered 60 males and 62 females whose parents had suffered premature ischemic stroke (PIS); the control group comprised of 41 males and 47 females whose parents had no history of premature vascular event (mean age: 28.4 and 27.1 years, respectively). Examination of both the groups consisted of evaluation of their diet, measurement of arterial blood pressure and body mass index (BMI). Moreover, blood test was carried out and concentration of biochemical stroke risk factors was determined. RESULTS: The adult progeny of parents with a history of PIS followed a deficient, unbalanced, and nonvaried diet. Their average blood pressure and BMI reached higher values, compared with the results obtained in the control group (125.7±16.06 vs. 122.64±10.83 mmHg; 24.27±3.98 vs. 22.54±2.69 kg/m, respectively; P<0.05). The same applies to average concentrations of the triglycerides 1.22±0.76 vs. 1.06±0.54 mmol/l; total cholesterol (5.34±1.16 vs. 4.82±0.89 mmol/l), low-density lipoprotein-cholesterol (2.95±0.97 vs. 2.52±0.73 mmol/l), total homocysteine (11.22±4.22 vs. 10.18±2.45 µmol/l), and fibrinogen (2.91±0.68 vs. 2.78±0.6 g/l) (P<0.05). CONCLUSION: Adult children of PIS sufferers show different stroke risk factor profiles than the control group. It may indicate a need for preventive activities for this group in the future. Family occurrence of stroke requires further detailed studies on a larger cohort of patients from risk group.

Occurrence and impact of back pain on the quality of life of healthcare workers.

INTRODUCTION AND OBJECTIVE: Back pain affects specific occupational groups, among which healthcare workers are the most predisposed. Therefore, the aim of this study was to determine the interdependences between subjective disability and their correlation with pain intensity and quality of life assessment among professionally active medical workers, taking into account working, socio-demographic and health conditions. MATERIAL AND METHODS: The cross-sectional study enrolled 110 professionally active medical workers (nurses, midwives, paramedics and physiotherapists). The study was conducted by a diagnostic survey method using 4 questionnaires: Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), World Health Organization Quality of Life BREF (WHOQoL-BREF), and the authors' questionnaire. RESULTS: Back pain was reported by 103 respondents (94%) with the lumbar area indicated the most frequently (72.81%). Severe pain every day was reported by 49.51% of respondents and was associated with longer working time. ODI questionnaire confirmed III and IV degrees of disability in paramedics and nurses, who additionally obtained the lowest results in the quality of life assessment. Correlations between age and VAS were demonstrated (p=0.002), and between VAS and ODI pain (p<0.0001) and ODI disability (p<0.0001). CONCLUSIONS: Back pain associated with professional activities is the consequence of overload. Health care workers should be included in a preventive programme and attend systematic ergonomics courses. Health care facilities should be retrofitted with equipment enabling work in accordance with the principles of ergonomics. The ODI questionnaire, together with the VAS method and scales for testing the quality of life, are useful tools in the clinical assessment of individuals with back pain.

Psychological factors and genetic characteristics of rural cannabis users.

INTRODUCTION: Marijuana is one of the most widely used psychoactive substance. There is evidence of genetic predisposition for addiction. OBJECTIVE: The aim of the study is to evaluate personality traits measured by the NEO Five-Factor Inventory and State-Trait Anxiety Inventory, combined with analysis of Tag1B rs1079597 and Tag1D rs1800498 located in the DRD2 gene. MATERIAL AND METHODS: The study group consisted of 214 rural cannabinoid users and 301 controls. The same psychometric test and real-time PCR genotyping were performed in both studied groups. RESULTS: The values of Anxiety state, Anxiety trait, NEO FFI: Neuroticism and Openness in the rural cannabis using group were significantly higher than in the control group. On the other hand, lower values were observed among rural people using cannabis compared to the control group for NEO FFI: Extraversion, Agreeability and Conscientiousness. In the Anxiety trait subscale, a 2% association with the polymorphism DRD2 Tag1B rs1079597 was detected in subjects using cannabis. However, for the DRD2 Tag1D rs1800498, there was no effect on the differences in personality traits between rural cannabis users and the control group. CONCLUSIONS: The study shows differences in personality traits between the cannabis using group and controls. Interaction between genetic factors and personality traits was also detected. The association showing the combination of psychological characteristics and genetic variants can bring us closer to the overall picture of the issue of marijuana addiction.

Significant association of DRD2 and ANKK1 genes with rural heroin dependence and relapse in men.

INTRODUCTION: Substance abuse significantly influences human health and may induce problems with social functioning worldwide. Numerous genetic and environmental risk factors, as well as their interactions, accelerate the development of drug addiction. Etiologically, the dopaminergic mesocorticolimbic reward pathways are related to psychoactive substance addiction, and the reward properties of heroin are connected with changes in the mesolimbic dopaminergic system. OBJECTIVE: The aim of this study is a haplotypic analysis of subjects addicted to polysubstance. However, with the knowledge that this is not a homogenous subgroup, it was decided to separate and analyze homogenous subgroups of subjects in order to find specific haplotypic variants among them. The subjects in the subgroups were addicted to heroin, and subjects with more than two relapses in the past two years. MATERIAL AND METHODS: The study group comprised of 301 polysubstance addicted rural male subjects. From this group, 2 homogenous subgroups of subjects were isolated and additionally analyzed: (1) a group of heroin addicted subjects (n=61), and (2) a group of heroin-addicted subjects with at least two relapses in the last two years (n=21). The group consisting of all polysubstance addicted rural subjects and both homogenous subgroups were analyzed against a control group of non-addicted subjects (n=300), matching gender and age. Five polymorphisms in the DRD2/ANKK1 region were analyzed: rs1076560, rs1800498, rs1079597, rs6276 in the DRD2 gene, and rs1800497 in the ANKK1 gene. RESULTS: A statistically significant haplotype association was found in analysis of the heroin addicted subjects, compared to controls, and two possible trends - when comparing the whole group of addicted subjects to controls, and in relapse subgroups, compared to the controls. CONCLUSIONS: The results obtained showed that haplotypes indicate a part of the biological component of addiction.

Effects of fenofibrate treatment on prothrombotic state in patients with metabolic syndrome in relation to smoking and diabetes.

BACKGROUND: Patients with metabolic syndrome (MS) are characterized by enhanced procoagulant activity caused by an increased fibrinogen (Fb) level, impaired fibrinolysis, and platelet activation. Fibrate treatment usually normalizes these conditions. The aim was to determine the effect of fenofibrate treatment on Fb level, fibrinolysis, and platelet function in patients with MS with regard to smoking status and type 2 diabetes. MATERIAL/METHODS: Sixty-four patients with MS, including 20 active smokers, without clinical features of coronary heart disease were enrolled in the study. Before and during treatment with fenofibrate all patients took antihypertensive drugs and 25 patients with type 2 diabetes used oral antidiabetic drugs. Before and after the treatment the levels of lipids, fasting glucose insulin, Fb, PAI-1, t-PA, and platelet function expressed as closure time (CT, after Coll/Epi and Coll/ADP) were measured. RESULTS: Fenofibrate treatment resulted in normalization of abnormal lipid profiles and a reduction in Fb level. In smokers an increase in PAI-1 level and CT shortening after Coll/Epi and after Coll/ADP were found. In nonsmokers, CT was prolonged only after Coll/Epi. A slight reduction in PAI-1 and a reduction in fasting glucose were noted in the diabetics. CONCLUSIONS: Fenofibrate partially corrected procoagulant state in patients with MS, which was manifested by a significant reduction in Fb level in all patients and inhibition of platelet function exclusively in nonsmokers. Smoking neutralizes the effects of treatment with fenofibrate as absence of inhibition of platelet function and a lack of improvement of the fibrinolysis system were observed in them.

[Selected dietary atherosclerosis risk factors in offspring of patients with premature ischemic stroke]. / Wybrane zywieniowe czynniki ryzyka miazdzycy u potomstwa chorych z przebytym przedwczesnym niedokrwiennym udarem mózgu.

UNLABELLED: There are currently multiple reports which conclude that there is a correlation between cardiovascular risk factors, including wrong dietary habits, and occurrence of these factors in families. AIM OF THE STUDY: To evaluate daily intake of selected dietary items, which have influence on premature development of atherosclerosis, in adult offspring of patients who underwent premature ischemic stroke. MATERIAL AND METHODS: 54 patients were included in the study: 21 males, aged 21-38 years (average 25.8 yrs.) and 33 women aged 19-39 years (average 28.2 yrs.). All of them were examined including medical history, physical examination and fasting blood draw. Dietary habits were evaluated with the method of 24-hour history using a questionnaire developed by Institute of Food and Diet in Warsaw, Poland (Instytut Zywnosci i Zywienia). Intake of selected dietary components (dietary cholesterol, fiber, vitamins E, C, B6, B12 and folic acid) was assessed using a computer program "Dietician 2" ("Dietetyk 2") which had been developed by the Institute of Food and Diet. RESULTS: In males, compared to females, there was a significantly higher (p < 0.05) level of daily calorie intake (2400.8 +/- 716.2 vs 1583.1 +/- 584.3 kcal) as well as intake (expressed in percentage of daily allowance) of dietary cholesterol (106.8 +/- 46.2 vs 62.9 +/- 42.8), fiber (70.6 +/- 28.2 vs 52.0 +/- 22.2), vitamin E (98.4 +/- 49.8 vs 63.5 +/- 33.9), folate (53.9 +/- 23.1 vs 37.8 +/- 16.4) and vitamin B12 (99.0 +/- 58.3 vs 57.2 +/- 44.5). There were also significantly higher levels of the following parameters in 22 normal-weight females compared to 11 overweight/obese females: daily calorie intake (1735.2 +/- 613.2 vs 1278.9 +/- 387.7 kcal) as well as intake (expressed in percentage of daily allowance) of dietary cholesterol (73.9 +/- 44.8 vs 40.9 +/- 29.2), folate (42.3 +/- 17.0 vs 28.7 +/- 10.9) and vitamin B12 (68.2 +/- 48.0 vs 35.1 +/- 26.4). CONCLUSIONS: The examined offspring (especially daughters) of a parent with premature ischemic stroke ate insufficient, unbalanced and monotonous diet, which impaired their nutrition. This should motivate family physicians to put greater interest in primary prevention in this group of patients. Overweight and obese women were put at even greater risk because such diet was added to other atherosclerosis risk factors, i.e. family history of premature ischemic stroke and increased body mass.

Attitudes and Learning through Practice Are Key to Delivering Brief Interventions for Heavy Drinking in Primary Health Care: Analyses from the ODHIN Five Country Cluster Randomized Factorial Trial.

In this paper, we test path models that study the interrelations between primary health care provider attitudes towards working with drinkers, their screening and brief advice activity, and their receipt of training and support and financial reimbursement. Study participants were 756 primary health care providers from 120 primary health care units (PHCUs) in different locations throughout Catalonia, England, The Netherlands, Poland, and Sweden. Our interventions were training and support and financial reimbursement to providers. Our design was a randomized factorial trial with baseline measurement period, 12-week implementation period, and 9-month follow-up measurement period. Our outcome measures were: attitudes of individual providers in working with drinkers as measured by the Short Alcohol and Alcohol Problems Perception Questionnaire; and the proportion of consulting adult patients (age 18+ years) who screened positive and were given advice to reduce their alcohol consumption (intervention activity). We found that more positive attitudes were associated with higher intervention activity, and higher intervention activity was then associated with more positive attitudes. Training and support was associated with both positive changes in attitudes and higher intervention activity. Financial reimbursement was associated with more positive attitudes through its impact on higher intervention activity. We conclude that improving primary health care providers' screening and brief advice activity for heavy drinking requires a combination of training and support and on-the-job experience of actually delivering screening and brief advice activity.
