Production, Consumption and Recent Changes of Consumption of Alcoholic Beverages

Accurate and reliable data on alcohol consumption and the production of alcoholic beverages are available mainly for western industrial countries. The consumption of each beverage type is highly concentrated in regions in which they are part of an established drinking culture. The rise of such a culture is based on both socio-economic and natural conditions of the production of the respective beverage type. Of the three beverage groups which are distinguished by international statistics, production and consumption of wine is most clearly concentrated in certain wine areas, whereas the prevalence of beer is independent of the production of grain. Spirits are mostly consumed in countries where also grain production is voluminous. This is interpreted so that a large part of present day beer consumption takes place in new circumstances and is not tied to old traditions and beer drinking cultures. The consumption of wine is still traditional to a much greater degree.     

Predictors of New Airway Obstruction – An 11 Year’s Population-Based Follow-Up Study

In the present study we aimed to investigate the incidence and predictors of spirometry based airway obstruction in a representative population-based sample. Altogether 3,863 subjects, 1,651 males and 2,212 females aged ≥30 years had normal spirometry in year 2000. Fifty-three percent of them were never and 23% current smokers. A re-spirometry was performed 11 years later. Several characteristics, such as level of education, use of alcohol, physical activity, diet using Alternate healthy eating (AHEI) index, body mass index, circumwaist, sensitive C reactive protein (CRP) and cotinine of the laboratory values and co-morbidities including asthma, allergic rhinitis, sleep apnoea and chronic bronchitis, as potential risk factors for airway obstruction were evaluated. Using forced expiratory volume in one second/ forced vital capacity below the lower limit of normal, we observed 124 new cases of airway obstruction showing a cumulative 11-year incidence of 3.2% and corresponding to an incidence rate of 5.6/1,000 per year (PY). The incidence rate was higher in men than in women (6.3/1,000 PY vs. 5.0/1,000 PY, respectively). The strongest risk factors were current smoking (Odds ratio [OR] 2.5) and previously diagnosed asthma (OR 2.1). Sensitive CRP associated with the increased risk and high AHEI index with the decreased risk of airway obstruction. Using the similar study approach our findings on the incidence of airway obstruction are in line with the previously published figures in Europe. We were able to confirm the recent findings on the protective effect of healthy diet.     

Celiac disease in patients with severe liver disease: gluten-free diet may reverse hepatic failure

BACKGROUND & AIMS: Mild liver abnormalities are common in patients with celiac disease and usually resolve with a gluten-free diet. We investigated the occurrence of celiac disease in patients with severe liver failure. METHODS: Four patients with untreated celiac disease and severe liver disease are described. Further, the occurrence of celiac disease was studied in 185 adults with previous liver transplantation using serum immunoglobulin A endomysial and tissue transglutaminase antibodies in screening. RESULTS: Of the 4 patients with severe liver disease and celiac disease, 1 had congenital liver fibrosis, 1 had massive hepatic steatosis, and 2 had progressive hepatitis without apparent origin. Three were even remitted for consideration of liver transplantation. Hepatic dysfunction reversed in all cases when a gluten-free diet was adopted. In the transplantation group, 8 patients (4.3%) had celiac disease. Six cases were detected before the operation: 3 had primary biliary cirrhosis, 1 had autoimmune hepatitis, 1 had primary sclerosing cholangitis, and 1 had congenital liver fibrosis. Only 1 patient had maintained a long-term strict gluten-free diet. Screening found 2 cases of celiac disease, 1 with autoimmune hepatitis and 1 with secondary sclerosing cholangitis. CONCLUSIONS: The possible presence of celiac disease should be investigated in patients with severe liver disease. Dietary treatment may prevent progression to hepatic failure, even in cases in which liver transplantation is considered.     

Bipolar radiofrequency thermal ablation of the soft palate in habitual snorers without significant desaturations assessed by magnetic resonance imaging

Sleep-disordered breathing, including habitual snoring, is a major health problem. Treatment of primary habitual snoring should be individualized using both conservative and active treatment methods. Active surgical interventions are, however, associated with significant morbidity. Therefore, procedures causing far less morbidity should be preferred. Our aim was to assess the efficacy and acceptability of bipolar radiofrequency thermal ablation of the soft palate in habitual snorers without significant desaturations associated with excessive daytime sleepiness. We treated 20 nonobese habitual snorers (median age, 43 years, range 35-63). All the patients had the major site of obstruction at the level of the soft palate, and they were treated on an outpatient basis in two treatment sessions separated by 1 week. The pretreatment and post-treatment symptoms and findings as well as the overall efficacy of the procedure were evaluated by questionnaires, visual analogue scales, and magnetic resonance imaging. All the questionnaires showed a statistically significant change, indicating decreased snoring and daytime sleepiness. The magnetic resonance studies showed that the procedure induced notable T1-signal alterations in the treated tissue, and when compared with the pretreatment images, certain dimensions of the soft palate were significantly changed. Bipolar radiofrequency thermal ablation of the soft palate seems to be well tolerated and effective regarding primary habitual snorers without significant desaturations associated with excessive daytime sleepiness.     

Screening for cardiovascular risk factors and self-rated health in a community setting: a cross-sectional study in Finland

Background

Self-rated health is an independent predictor of mortality. However, general health checks in populations unselected for disease or risk factors have not been shown to reduce mortality or morbidity.

Aim

To describe new comorbidities and cardiovascular risk factors in apparently healthy people and to relate this to their self-rated health.

Design and setting

A targeted screening programme identified 462 middle-aged people with cardiovascular risk factors without previously diagnosed chronic disease in a Finnish community in 2005–2006.

Method

Home blood pressure monitoring, oral glucose tolerance test, estimated glomerular filtration rate, and ankle brachial index were used to detect previously undiagnosed conditions. The Short-Form Health Survey and Beck’s Depression Inventory were completed by participants before the diagnostic tests were performed.

Results

The prevalence of previously undiagnosed disease was: hypertension 113/462 (24% [95% confidence interval {CI} = 21% to 29%]), diabetes 19/462 (4% [95% CI = 2% to 6%]), renal insufficiency 23/462 (5% [95% CI = 3% to 7%]), and peripheral arterial disease 17/462 (4% [95% CI = 2% to 5%]). Of the 139 participants who regarded their health as ‘fair–poor’, 60 (43%) had a previously undetected condition affecting their vasculature.

Conclusion

Out of the screen-detected apparently healthy cardiovascular risk subjects, one in three had undiagnosed hypertension, diabetes, peripheral arterial disease, or renal insufficiency. Those individuals experiencing ill health tended to be at high risk of cardiovascular problems.     

Fragment‐ and negative image‐based screening of phosphodiesterase 10A inhibitors

A novel virtual screening methodology called fragment‐ and negative image‐based (F‐NiB) screening is introduced and tested experimentally using phosphodiesterase 10A (PDE10A) as a case study. Potent PDE10A‐specific small‐molecule inhibitors are actively sought after for their antipsychotic and neuroprotective effects. The F‐NiB combines features from both fragment‐based drug discovery and negative image‐based (NIB) screening methodologies to facilitate rational drug discovery. The selected structural parts of protein‐bound ligand(s) are seamlessly combined with the negative image of the target's ligand‐binding cavity. This cavity‐ and fragment‐based hybrid model, namely its shape and electrostatics, is used directly in the rigid docking of ab initio generated ligand 3D conformers. In total, 14 compounds were acquired using the F‐NiB methodology, 3D quantitative structure–activity relationship modeling, and pharmacophore modeling. Three of the small molecules inhibited PDE10A at ~27 to ~67 μM range in a radiometric assay. In a larger context, the study shows that the F‐NiB provides a flexible way to incorporate small‐molecule fragments into the drug discovery.
