A Pilot Study on Zinc Levels in Patients with Rheumatoid Arthritis

The aim of the study was to evaluate zinc levels in three biological compartments (serum, erythrocytes and hair) in patients with rheumatoid arthritis (RA) as compared to healthy individuals. Zinc levels in serum, erythrocytes and hair (in 74 patients with RA and 30 healthy individuals) were assessed by atomic absorption spectroscopy. The mean hair zinc content was significantly lower in RA patients as compared to healthy individuals (p < 0.001). Moreover, a positive correlation was observed in the RA patient group between the erythrocyte zinc levels and the prednisone dose (rs = 0.48, p < 0.05), and a negative correlation was found in this population between the serum zinc levels and disease duration (rs = −0.42, p < 0.0006). In conclusion, it seems that hair may be a useful complementary study material for evaluating “zinc status” in rheumatoid arthritis patients

Chemical ideas and the development of chemical and petroleum industry on the Polish territory since 1850 to 1920

The information about: 1) the liquefaction of oxygen and nitrogen in 1883 in Kraków, 2) the formulation in Lwow of the hypothesis of vegetal origin of crude oil, 3) the discovery of chromatography in 1903 in Warsaw, is given. The situation of chemical industry in the three parts of Poland partitioned among Russia, Germany and Austria is reported. A special attention is paid to the activity of Ignacy Łukasiewicz, who received for the first time in the world the kerosene from the crude oil, constructed and lighted in Lwow pharmacy in March 1853 the kerosene lamp. In 1854 he excavated petroleum shaft in Bóbrka and in 1856 he built a petroleum refinery in Ulaszowice near Jasło, getting ahead of USA, where the first petroleum refinery at Oil Creek was built five years later, in 1861

Incidental chest radiographic findings in adult patients with acute cough

PURPOSE Imaging may produce unexpected or incidental findings with consequences for patients and ordering of future investigations. Chest radiography in patients with acute cough is among the most common reasons for imaging in primary care, but data on associated incidental findings are lacking. We set out to describe the type and prevalence of incidental chest radiography findings in primary care patients with acute cough. METHODS We report on data from a cross-sectional study in 16 European primary care networks on 3,105 patients with acute cough, all of whom were undergoing chest radiography as part of a research study workup. Apart from assessment for specified signs of pneumonia and acute bronchitis, local radiologists were asked to evaluate any additional finding on the radiographs. For the 2,823 participants with good-quality chest radiographs, these findings were categorized according to clinical relevance based on previous research evidence and analyzed for type and prevalence by network, sex, age, and smoking status. RESULTS Incidental findings were reported in 19% of all participants, and ranged from 0% to 25% by primary care network, with the network being an independent contributor (P < .001). Of all participants 3% had clinically relevant incidental findings. Suspected nodules and shadows were reported in 1.8%. Incidental findings were more common is older participants and smokers (P < .001). CONCLUSIONS Clinically relevant incidental findings on chest radiographs in primary care adult patients with acute cough are uncommon, and prevalence varies by setting

Attitudes and delivering brief interventions for heavy drinking in primary health care: analyses from the ODHIN five country cluster randomized factorial trial

Contains fulltext : 170028.pdf (publisher's version ) (Open Access)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

Impact of practice, provider and patient characteristics on delivering screening and brief advice for heavy drinking in primary health care secondary analyses of data from the ODHIN five country cluster randomized factorial trial

BACKGROUND: The implementation of primary healthcare-based screening and advice that is effective in reducing heavy drinking can be enhanced with training. OBJECTIVES: Undertaking secondary analysis of the five-country ODHIN study, we test: the extent to which practice, provider and patient characteristics affect the likelihood of patients being screened and advised; the extent to which such characteristics moderate the impact of training in increasing screening and advice; and the extent to which training mitigates any differences due to such characteristics found at baseline. METHODS: A cluster randomized factorial trial involving 120 practices, 746 providers and 46 546 screened patients from Catalonia, England, the Netherlands, Poland, and Sweden. Practices were randomized to receive training or not to receive training. The primary outcome measures were the proportion of adult patients screened, and the proportion of screen-positive patients advised. RESULTS: Nurses tended to screen more patients than doctors (OR = 3.1; 95%CI: 1.9, 4.9). Screen-positive patients were more likely to be advised by doctors than by nurses (OR = 2.3; 95%CI: 1.4, 4.1), and more liable to be advised the higher their risk status (OR = 1.9; 95%CI: 1.3, 2.7). Training increased screening and advice giving, with its impact largely unrelated to practice, provider or patient characteristics. Training diminished the differences between doctors and nurses and between patients with low or high-risk status. CONCLUSIONS: Training primary healthcare providers diminishes the negative impacts that some practice, provider and patient characteristics have on the likelihood of patients being screened and advised.

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.peer-reviewe

Healthy diet in primary care: views of general practitioners and nurses from Europe

Background: Most of the national colleges of general practitioners (GPs) do not have their own dietary/nutritional tools, and GPs and nurses do not have the time, knowledge, or skills to advise their patients about desirable dietary practices. Objective: To assess the usefulness of a simple and practical guide on healthy diet to be used by European GPs and nurses. Design: A postal survey was mailed to 171 GPs and nurses from 12 European countries to obtain information about the usefulness of a guide on healthy diet developed by EUROPREV. Results: The perception of health professionals is that the main source of information on healthy diet for the population was the media. In all, 95% of GPs and nurses reported that the guide was useful; 93, 95, and 82% reported that the concepts were concise, easy to understand, and realistic, respectively. Also, 77% reported that the type of counselling recommended was feasible and could be applied, 94% reported that the implementation measures proposed could be effective and 88% reported that the Traditional Mediterranean Diet Pyramid is useful, but some concerns about the content were mentioned. Conclusions: GPs and nurses from Europe think that a practical guide on healthy diet developed by EUROPREV could be used to advise patients in primary care, although the Traditional Mediterranean Diet Pyramid should be modified
