Total Consumption (total + consumption)
Selected AbstractsFruit and vegetable consumption and pancreatic cancer risk in the European Prospective Investigation into Cancer and NutritionINTERNATIONAL JOURNAL OF CANCER, Issue 8 2009Alina Vrieling Abstract Many case-control studies have suggested that higher consumption of fruit and vegetables is associated with a lower risk of pancreatic cancer, whereas cohort studies do not support such an association. We examined the associations of the consumption of fruits and vegetables and their main subgroups with pancreatic cancer risk within the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is comprised of over 520,000 subjects recruited from 10 European countries. The present study included 555 exocrine pancreatic cancer cases after an average follow-up of 8.9 years. Estimates of risk were obtained by Cox proportional hazard models, stratified by age at recruitment, gender, and study center, and adjusted for total energy intake, weight, height, history of diabetes mellitus, and smoking status. Total consumption of fruit and vegetables, combined or separately, as well as subgroups of vegetables and fruits were unrelated to risk of pancreatic cancer. Hazard ratios (95% CI) for the highest versus the lowest quartile were 0.92 (0.68,1.25) for total fruit and vegetables combined, 0.99 (0.73,1.33) for total vegetables, and 1.02 (0.77,1.36) for total fruits. Stratification by gender or smoking status, restriction to microscopically verified cases, and exclusion of the first 2 years of follow-up did not materially change the results. These results from a large European prospective cohort suggest that higher consumption of fruit and vegetables is not associated with decreased risk of pancreatic cancer. © 2008 Wiley-Liss, Inc. [source] Efficacy of bupivacaine-neostigmine and bupivacaine-tramadol in caudal block in pediatric inguinal herniorrhaphyPEDIATRIC ANESTHESIA, Issue 9 2010REZA TAHERI MD Summary Background:, Limited duration of analgesia is among the limitations of single caudal injection with local anesthetics. Therefore, the purpose of this study was to evaluate the effectiveness and safety of bupivacaine in combination with either neostigmine or tramadol for caudal block in children undergoing inguinal herniorrhaphy. Methods:, In a double-blinded randomized trial, sixty children undergoing inguinal herniorrhaphy were enrolled to receive a caudal block with either 0.25% bupivacaine (1 ml·kg,1) with neostigmine (2 ,g·kg,1) (group BN) or tramadol (1 mg·kg,1) (group BT). Hemodynamic variables, pain and sedation scores, additional analgesic requirements, and side effects were compared between two groups. Results:, Duration of analgesia was longer in group BT (17.30 ± 8.24 h) compared with group BN (13.98 ± 10.03 h) (P = 0.03). Total consumption of rescue analgesic was significantly lower in group BT compared with group BN (P = 0.04). There were no significant differences in heart rate, mean arterial pressure, and oxygen saturation between groups. Adverse effects excluding the vomiting were not observed in any patients. Conclusion:, In conclusion, tramadol (1 mg·kg,1) compared with neostigmine (2 ,g·kg,1) might provide both prolonged duration of analgesia and extended time to first analgesic in caudal block. [source] Increasing herbal product consumption in Thailand,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 9 2006Arthorn Riewpaiboon PhD Abstract Purpose The aim of this study was to investigate expenditures and categories of herbal product consumption in drugstores in Thailand. Methods The study was designed as a cross-sectional descriptive research. Study population was drugs and foods produced from herbs sold in all registered drugstores in Thailand. Regarding sampling, one province was selected from each of 13 regions by convenience sampling. Drugstores in each province were included at a proportion of 1% of the population by a convenience sampling method. Purchasing documents of the drugstores were collected for two consecutive months in 2001 and 2003. The medians of prices were used to estimate value of the whole country. Results The sample included 129 and 121 drugstores in 2001 and 2003, respectively. Total consumption was 27 and 32 million US$ (1 US$,=,40 Thai baht) in the year 2001 and 2003, respectively. At constant prices, this represented an increase of 11%. The five top-ranked categories of products used in 2003 were haematonics, post-delivery drugs, anti-constipation, anti-cough, and cardiotonics. Conclusions Herbal product consumption increased by 11% from 2001 to 2003. To cover the full range of consumption of herbal products, further studies should include other outlets, for example hospital and direct sales. Copyright © 2005 John Wiley & Sons, Ltd. [source] Development of learned flavor preferencesDEVELOPMENTAL PSYCHOBIOLOGY, Issue 5 2006Kevin P. Myers Abstract Rats, like humans, are born with only a few innate flavor preferences and aversions. Preferences retain great plasticity throughout the lifespan because they are sensitive to modification by experience. From an early age, rats can rapidly learn to prefer or avoid a flavor (conditioned stimulus, CS) that is associated with a positive or negative unconditioned stimulus (US). The US may be the mother's milk, social or thermotactile stimulation, or other food-related stimuli. Flavor-flavor learning occurs when the CS flavor is mixed with a naturally preferred (e.g., sweet) or avoided (e.g., bitter) US flavor. Flavor preferences and aversions are also produced by USs that have postoral positive (e.g., nutritious) or negative (e.g., toxic) actions. These types of learning appear to involve different behavioral and neural mechanisms as indicated by differences in conditioned responses, effective temporal parameters, resistance to extinction, and neurochemical mechanisms. New evidence indicates that flavor-nutrient preference learning can occur before weaning and influence food selection after weaning. Flavor conditioning not only affects food choice, but can also significantly increase food acceptance, that is, total consumption. Thus, from an early age, learning processes shape the feeding behavior of animals. While primarily serving an adaptive function, learning may play a role in biasing individuals towards excessive intake and weight gain. © 2006 Wiley Periodicals, Inc.

[source] Effects of elevated CO2 associated with maize on multiple generations of the cotton bollworm, Helicoverpa armigeraENTOMOLOGIA EXPERIMENTALIS ET APPLICATA, Issue 1 2010Jin Yin Abstract Under elevated environmental carbon dioxide (CO2), leaf chewers tend to compensate for decreased leaf nutritional quality with increased consumption; mortality and development times also increase and cause a reduction in the fitness of leaf chewers. However, the effect of elevated CO2 on multiple successive generations of these and other insects is not well understood. Furthermore, information about the direct effects of increased environmental CO2 on developmental time and consumption of herbivores is lacking. In this paper, we tested the hypothesis that cascade effects of elevated CO2 through plants, rather than the direct effects of elevated CO2, are the main factors decreasing the fitness of cotton bollworm, Helicoverpa armigera Hübner (Lepidoptera: Noctuidae). We used two series of experiments to quantify the growth, development, and consumption of H. armigera fed on an artificial diet or C4 plants (maize) grown under two CO2 levels (ambient vs. double ambient). In the first series of experiments, elevated CO2 had no effect on the population abundance or individual consumption for three successive generations of cotton bollworms fed on an artificial diet. In the second series of experiments, elevated CO2 reduced population abundance of cotton bollworm larvae for two successive generations when they were fed maize milky grains. The specific effects were longer larval duration, lower fecundity, and decreased rm of cotton bollworms. Furthermore, elevated CO2 increased individual consumption when cotton bollworm was fed maize milky grains for two successive generations and decreased the population's total consumption in the first generation but increased it in the second generation. The results from this study indicate that: (1) The effects of elevated CO2 on three successive generations of cotton bollworm fed on artificial diet were weak, or even non-existent, and (2) elevated CO2 increased the consumption when cotton bollworm were fed maize. Our study also suggests that the damage inflicted by cotton bollworm on maize (a C4 plant) will be seriously affected by the increases in atmospheric CO2, which is unlike our previous results for spring wheat (a C3 plant). [source] PRECLINICAL STUDY: FULL ARTICLE: Repeated ethanol administration modifies the temporal structure of sucrose intake patterns in mice: effects associated with behavioral sensitizationADDICTION BIOLOGY, Issue 3 2010Raúl Pastor ABSTRACT Neuroadaptations supporting behavioral sensitization to abused drugs are suggested to underlie pathological, excessive motivation toward drugs and drug-associated stimuli. Drug-induced sensitization has also been linked to increased appetitive responses for non-drug, natural reinforcers. The present research investigated whether ethanol (EtOH)-induced neural changes, inferred from psychomotor sensitization, can modify consumption and intake dynamics for the natural reinforcer, sucrose. The effects of EtOH-induced sensitization in mice on the temporal structure of sucrose intake patterns were measured using a lickometer system. After sensitization, sucrose intake dynamics were measured for 1 hour daily for 7 days and indicated more rapid initial approach and consumption of sucrose in EtOH-sensitized groups; animals showed a shorter latency to the first intake bout and an increased number of sucrose bottle licks during the initial 15 minutes of the 1-hour sessions. This effect was associated with increased frequency and size of bouts. For the total 1-hour session, sucrose intake and bout dynamics were not different between groups, indicating a change in patterns of sucrose intake but not total consumption. When sensitization was prevented by the ,-aminobutyric acid B receptor agonist, baclofen, the increased rate of approach and consumption of sucrose were also prevented. Thus, EtOH-induced sensitization, and not the mere exposure to EtOH, was associated with changes in sucrose intake patterns. These data are consistent with current literature suggesting an enhancing effect of drug-induced sensitization on motivational processes involved in reinforcement. [source] The Impact of a Conditional Cash Transfer Programme on Consumption in Colombia,FISCAL STUDIES, Issue 4 2006Orazio Attanasio Abstract This paper studies the impact of a conditional cash transfer programme in Colombia on the total consumption of very poor households and on its components. Our evaluation methodology involves comparing household expenditures in areas in which the programme was not implemented (control) and those in which it was (treated). We use a quasi-experimental approach, as the Familias en Acción programme was not randomly assigned across localities, for political reasons. We condition on a large range of household- and municipality-level characteristics, and also control for pre-programme differences in the outcomes of interest using a differences-indifferences methodology. We find that the programme has been effective at greatly increasing total consumption and its main component, food consumption, in both rural and urban areas. The programme has also contributed to improvements in the quality of food consumed, in particular of items rich in proteins (milk, meat and eggs) and of cereals. Furthermore, the programme has created redistributive effects in favour of children through expenditure on education and children's clothing, while it has not significantly affected consumption of adult goods such as alcohol and tobacco or adults'clothing. [source] Dextropropoxyphene withdrawal from a French university hospital: impact on analgesic drug consumptionFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 2 2009Sabine Gaubert Abstract Dextropropoxyphene is a weak opioid analgesic, widely used as a step 2 analgesic (according to WHO classification) in combination with peripheral analgesics, mainly paracetamol. Recent data have underlined its poor analgesic efficacy (in comparison with paracetamol), risks of serious adverse drug reactions (i.e. hepatic reactions, hallucinations, abuse, withdrawal symptoms, hypoglycaemia), possible lethality after overdose, its risk of accumulation in patients with renal failure or in elderly people and some pharmacokinetic insufficiencies (i.e. different half-lives for dextropropoxyphene and paracetamol). Taking into account these data, the drug committee of the Toulouse University Hospital (France) decided to withdraw dextropropoxyphene from the hospital formulary since 1 June 2005. The aim of our study was to investigate the consequences of this withdrawal by comparing use of analgesic drugs in Toulouse University Hospital before (2004) and after (2006) dextropropoxyphene withdrawal (using defined daily dose for 1000 hospitalization-days as the unit measure). Before withdrawal, dextropropoxyphene (in combination with paracetamol) was the second most used analgesic drug after paracetamol alone. After dextropropoxyphene withdrawal, total consumption of analgesic drugs decreased by 4.6% (2006 vs. 2004). There was a 28% decrease in consumption of step 2 analgesics [with an increase in oral tramadol and a slight decrease in codeine (in combination with paracetamol)]. During the same period, step 1 analgesic consumption increased by 11% (mainly paracetamol) and that of step 3 analgesics slightly decreased (,8%). These results show that dextropropoxyphene withdrawal was not associated with a marked switch in prescriptions towards other analgesic drugs. This paper underlines the interest of a hospital-based drug committee to promote rational drug use. Finally, the present data allow us to discuss putative misuse of dextropropoxyphene. [source] Fruits and vegetables and renal cell carcinoma: Findings from the European prospective investigation into cancer and nutrition (EPIC)INTERNATIONAL JOURNAL OF CANCER, Issue 12 2006Steffen Weikert Abstract We examined the association between fruits and vegetables and risk of renal cell carcinoma (RCC) in the European Prospective Investigation into Cancer and Nutrition (EPIC). Dietary intake data and complete follow-up information on cancer incidence were available for 375,851 participants recruited in EPIC centers of 8 countries. During an average follow-up of 6.2 years, 306 incident cases of RCC were identified. The associations of consumption of total vegetables, total fruits, combined total fruits and vegetables and specific subtypes of vegetables with RCC risk were analyzed using Cox proportional hazards, stratified by centre and adjusted for potential confounders. No significant associations between fruit and vegetable consumption and RCC risk were observed despite a wide range of intake. The estimated relative risks (95% confidence intervals [CI]) in men and women combined were 0.97 (0.85,1.11) per 40 g increase in vegetable intake, 1.03 (0.97,1.08) per 40 g increase in fruit intake and 1.02 (0.93,1.11) per 80 g increase in fruit and vegetable intake combined. Among the vegetable subtypes, an inverse association was observed for root vegetables (RR per 8 g increase: 0.88; 95% CI: 0.78,0.99). These results suggest that total consumption of fruits and vegetables is not related to risk of RCC, although we cannot exclude the possibility that very low consumption is related to higher risk. The relationship of specific fruit and vegetable subgroups with RCC risk warrant further investigation. © 2006 Wiley-Liss, Inc. [source] Impact of the CYP2D6 genotype on post-operative intravenous oxycodone analgesiaACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2010S. T. ZWISLER Background: Oxycodone is a semi-synthetic opioid with a ,-receptor agonist-mediated effect in several pain conditions, including post-operative pain. Oxycodone is metabolized to its active metabolite oxymorphone by O -demethylation via the polymorphic CYP2D6. The aim of this study was to investigate whether CYP2D6 poor metabolizers (PMs) yield the same analgesia post-operatively from intravenous oxycodone as extensive metabolizers (EMs). Methods: Two hundred and seventy patients undergoing primarily thyroid surgery or hysterectomy were included and followed for 24 h post-operatively. The CYP2D6 genotype was blinded until study procedures had been completed for all patients. All patients received intravenous oxycodone as pain treatment for 24 h post-operatively and morphine 5 mg was used as escape medication. A responder was characterized as a patient without the need for escape medication and a positive evaluation in a questionnaire 24 h post-operatively. Results: Twenty-four patients were PM (8.9%) and 246 were EM (91.1%). One PM (4.17%, CI=0.1,21.1) was a non-responder and 42 EM (17.07%, CI=12.6,22.4) were non-responders. The non-responder rate did not differ between the two genotypes (P=0.14). There was no difference in the total consumption of oxycodone between the two genotypes (EM=14.7 mg, CI=13.0,16.4 and PM=13.0 mg, CI=8.9,17.0, P=0.42). The mean oxymorphone/oxycodone ratios were 0.0031 and 0.00081 in the EMs and PMs, respectively (P<0.0001). Conclusion: This study showed for the first time in patients that the oxymorphone formation depends on CYP2D6, but we found no difference in the post-operative analgesic effect of intravenous oxycodone between the two CYP2D6 genotypes. [source] Comparison of feed preference and digestion of three different commercial diets for cats and ferretsJOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 3-6 2005S. Gy. Summary Diet preference and digestibility experiments were conducted using a total of 10 cats and 10 ferrets. The composition of the three different kinds of dry cat feed was as follows (each data are given in dry matter, DM): (i) normal diet (N): 95.3% DM, 33.7% crude protein (CP), 20.4% ether extract (EE), 37.6% nitrogen-free extract (NFE); (ii) ,light diet' (L): 94.2% DM, 31.6% CP, 10.7% EE, 52.2% NFE; (iii) ,veterinary diet' (D): 94.57% DM, 38.7% CP, 9.6% EE, 47.2% NFE. During the period of the preference test, the average daily dry matter intake (calculated with the mean of the three diets: 94.7% DM) was 98.0, 15.0 and 16.7 g DM in cats and 25.0, 7.3 and 8.1 g DM in ferrets. The preference rates of the three different diets, expressed in percentage of their total consumption, were as follows: 60.4% N (54.4 g DM), 12.4% L (12.1 g DM) and 27.2% D (26.6 g DM) in cats, and 46.2% N (11.6 g DM), 29.9% L (7.5 g DM) and 23.9% D (6.0 g DM) in ferrets. This indicates that cats and ferrets have a clear preference for diets of higher fat content. In all three diets, the digestibility of CP was significantly (p < 0.05) lower (70.1 ± 5.4 vs. 75.9 ± 5.8) while that of EE was significantly (p < 0.05) higher (95.6 ± 1.5 vs. 89.4 ± 5.3) in ferrets than in cats. The average digestible/metabolizable energy (DE/ME) ratio of feeds turned to be 95.6% for cats and 90.6% for the ferrets. From the data one can conclude that the ferret cannot be used as a model animal for cats either for preference or digestibility studies. [source] Feeding efficiency of planktivorous perch Perca fluviatilis and roach Rutilus rutilus in varying turbidity: an individual-based approachJOURNAL OF FISH BIOLOGY, Issue 7 2010L. Nurminen The feeding rate of perch Perca fluviatilis showed high individual variation at low and moderate turbidities, when one individual had consumed more Daphnia pulex than any other fish, whereas no such variation in feeding efficiency was observed with roach Rutilus rutilus. There was a significant decrease in total consumption of D. pulex by P. fluviatilis with increasing turbidity, but no correlation was observed in the case of R. rutilus. The results suggest that the difference in the ontogeny of P. fluviatilis and R. rutilus may be detectable as behaviour-related species-specific trait differences in the early planktivorous feeding stage of the two common species. [source] Environmental Impacts of Consumption in the European Union:High-Resolution Input-Output Tables with Detailed Environmental ExtensionsJOURNAL OF INDUSTRIAL ECOLOGY, Issue 3 2006Gjalt Huppes Summary For developing product policy, insight into the environmental effects of products is required. But available life-cycle assessment studies (LCAs) are hardly comparable between different products and do not cover total consumption. Input-output analysis with environmental extensions (EEIOA) of full consumption is not available for the European Union. Available country studies have a low sector resolution and a limited number of environmental extensions. This study fills the gap between detailed LCA and low-resolution EEIOA, specifying the environmental effects of household consumption in the European Union, discerning nearly 500 sectors, while specifying a large number of environmental extensions. Added to the production sectors are a number of consumption activities with direct emissions, such as automobile driving, cooking and heating, and a number of postconsumer waste management sectors. The data for Europe have been constructed by using the sparse available and coarse economic and environmental data on European countries and adding technological detail mainly based on data from the United States. A small number of products score high on environmental impact per Euro and also have a substantial share of overall consumer expenditure. Several meat and dairy products, household heating, and car driving thus have a large share of the total environmental impact. Due to their sales volume, however, products with a medium or low environmental score per Euro may also have a substantial impact. This is the case with bars and restaurants, clothing, residential construction, and even a service such as telecommunications. The limitations in real European data made heroic assumptions necessary to operationalize the model. One conclusion, therefore, is that provision of data in Europe urgently needs to be improved, at least to the level of sector detail currently available for the United States and Japan. [source] Effect of dexmedetomidine on the characteristics of bupivacaine in a caudal block in pediatricsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2009I. SAADAWY Background: Dexmedetomidine (DEX) is a highly selective ,2 -adrenoceptor agonist that has been used increasingly in children. However, the effect of caudal DEX has not been evaluated before in children. This prospective randomized double-blinded study was designed to evaluate the analgesic efficacy of caudal DEX with bupivacaine in providing pain relief over a 24-h period. Methods: Sixty children (ASA status I) aged 1,6 years undergoing unilateral inguinal hernia repair/orchidopexy were allocated randomly to two groups (n=30 each). Group B received a caudal injection of bupivacaine 2.5 mg/ml, 1 ml/kg; Group BD received the same dose of bupivacaine mixed with DEX 1 ,g/kg during sevoflurane anesthesia. Processed electroencephalogram (bispectral index score), heart rate, blood pressure, pulse oximetry and end-tidal sevoflurane were recorded every 5 min. The characteristics of emergence, objective pain score, sedation score and quality of sleep were recorded post-operatively. Duration of analgesia and requirement for additional analgesics were noted. Results: The end-tidal sevoflurane concentration and the incidence of agitation were significantly lower in the BD group (P<0.05). The duration of analgesia was significantly longer (P<0.001) and the total consumption of rescue analgesic was significantly lower in Group BD compared with Group B (P<0.01). There was no statistically significant difference in hemodynamics between both groups. However, group BD had better quality of sleep and a prolonged duration of sedation (P<0.05). Conclusion: Caudal DEX seems to be a promising adjunct to provide excellent analgesia without side effects over a 24-h period. It has the advantage of keeping the patients calm for a prolonged time. Implications statement: Caudally administered DEX (1 ,g/kg), combined with bupivacaine, was associated with an extended duration of post-operative pain relief. [source] Association Between Quality of Cheap and Unrecorded Alcohol Products and Public Health Consequences in PolandALCOHOLISM, Issue 10 2009Dirk W. Lachenmeier Background:, The research aimed to study the quality of cheap alcohol products in Poland. These included unrecorded alcohols (i.e., home-produced or illegally imported), estimated to constitute more than 25% of total consumption and fruit wines. Methods:, A sample of alcohol products (n = 52) was collected from local markets and chemical analyses were conducted. The parameters studied were alcoholic strength, volatiles (methanol, acetaldehyde, and higher alcohols), ethyl carbamate, inorganic elements, and food additives including preservatives, colors, and sweeteners. The compositions of the beverages were then toxicologically evaluated using international standards. Results:, With the exception of 1 fortified wine, the unrecorded alcohols were home-produced fruit-derived spirits (moonshine) and spirits imported from other countries. We did not detect any nonbeverage surrogate alcohol. The unrecorded spirits contained, on average, 45% vol of alcohol. However, some products with considerably higher alcoholic strengths were found (up to 85% vol) with no labeling of the content on the bottles. These products may cause more pronounced detrimental health effects (e.g., liver cirrhosis, injuries, some forms of malignant neoplasms, alcohol use disorders, and cardiovascular disease) than will commercial beverages, especially as the consumer may be unaware of the alcohol content consumed. Fruit wines containing between 9.5 and 12.2% vol alcohol showed problems in terms of their additive content and their labeling (e.g., sulfites, sorbic acid, saccharin, and artificial colors) and should be subjected to stricter control. Regarding the other components investigated, the suspected human carcinogens, acetaldehyde and ethyl carbamate, were found at levels relevant to public health concerns. While acetaldehyde is a typical constituent of fermented beverages, ethyl carbamate was found only in home-produced unrecorded alcohols derived from stone fruits with levels significantly above international guidelines. Conclusions:, The contamination of unrecorded alcohols with ethyl carbamate should be analyzed in a larger sample that also should include legal alcoholic beverages. Furthermore, the impacts of unrecorded alcohol on the health of people with lower socioeconomic status should be studied in detail. Overall, given the extent of the alcohol-attributable disease burden in Poland, the highest priority should be given to the problem of ethanol and its very high content in unrecorded alcohol products. [source] The Hispanic Americans Baseline Alcohol Survey: Alcoholic Beverage Preference Across Hispanic National GroupsALCOHOLISM, Issue 1 2009Raul Caetano Background:, U.S. Hispanics come from many countries in Latin America, which can lead to different beverage preferences in the United States. This paper examines choice for drinking wine, beer, and liquor across 4 Hispanic national groups: Mexican Americans, Puerto Ricans, Cuban Americans, and South/Central Americans. Methods:, A sample of 5,224 individuals 18 years of age and older was selected using multistage cluster procedures from the household population in 5 metropolitan areas of the United States: Miami, New York, Philadelphia, Houston, and Los Angeles. The survey weighted response rate was 76%. Face-to-face interviews lasting 1 hour on average were conducted in the respondents' homes either in English or Spanish. Results:, Among men, beer drinkers consume the highest mean number of drinks per week in all national groups. Among women, this is true only of Puerto Ricans and Mexican Americans. Among men who drink beer, beer drinking constitutes 52 to 72% of total alcohol consumption. Among women who drink beer, beer consumption is associated with 32 to 64% of total consumption. Beer is the beverage most associated with binge drinking among Puerto Rican and Mexican American women, while among Cuban Americans and South/Central Americans this is seen for wine. Regression analyses showed no significant differences by national group in the likelihood of drinking 2 or fewer drinks (vs. no drinks) of wine, beer, or liquor. Puerto Ricans were more likely (OR = 1.47; 95% CI = 1.00,2.14) than Cuban Americans to drink 3 or more drinks (compared with no drinks) of beer. There was no association between the likelihood of binge drinking and Hispanic national group. Conclusions:, Beverage preference across Hispanic national groups is similar. Beer is the preferred beverage. Alcohol control policies such as taxation and control of sales availability should apply equally to beer, liquor, and wine. Prevention interventions directed at different Hispanic national groups in the United States can be relatively uniform in their focus on the dangers associated with drinking different types of alcoholic beverages. [source] Effects of CO2 and light on tree phytochemistry and insect performanceOIKOS, Issue 2 2000Jep Agrell Direct and interactive effects of CO2 and light on tree phytochemistry and insect fitness parameters were examined through experimental manipulations of plant growth conditions and performance of insect bioassays. Three species of deciduous trees (quaking aspen, Populus tremuloides; paper birch, Betula papyrifera; sugar maple, Acer saccharum) were grown under ambient (387±8 ,L/L) and elevated (696±2 ,L/L) levels of atmospheric CO2, with low and high light availability (375 and 855 ,mol×m,2×s,1 at solar noon). Effects on the population and individual performance of a generalist phytophagous insect, the white-marked tussock moth (Orgyia leucostigma) were evaluated. Caterpillars were reared on experimental trees for the duration of the larval stage, and complementary short-term (fourth instar) feeding trials were conducted with insects fed detached leaves. Phytochemical analyses demonstrated strong effects of both CO2 and light on all foliar nutritional variables (water, starch and nitrogen). For all species, enriched CO2 decreased water content and increased starch content, especially under high light conditions. High CO2 availability reduced levels of foliar nitrogen, but effects were species specific and most pronounced for high light aspen and birch. Analyses of secondary plant compounds revealed that levels of phenolic glycosides (salicortin and tremulacin) in aspen and condensed tannins in birch and maple were positively influenced by levels of both CO2 and light. In contrast, levels of condensed tannins in aspen were primarily affected by light, whereas levels of ellagitannins and gallotannins in maple responded to light and CO2, respectively. The long-term bioassays showed strong treatment effects on survival, development time, and pupal mass. In general, CO2 effects were pronounced in high light and decreased along the gradient aspen birch maple. For larvae reared on high light aspen, enriched CO2 resulted in 62% fewer survivors, with increased development time, and reduced pupal mass. For maple-fed insects, elevated CO2 levels had negative effects on survival and pupal mass in low light. For birch, the only negative CO2 effects were observed in high light, where female larvae showed prolonged development. Fourth instar feeding trials demonstrated that low food conversion efficiency reduced insect performance. Elevated levels of CO2 significantly reduced total consumption, especially by insects on high light aspen and low light maple. This research demonstrates that effects of CO2 on phytochemistry and insect performance can be strongly light-dependent, and that plant responses to these two environmental variables differ among species. Overall, increased CO2 availability appeared to increase the defensive capacity of early-successional species primarily under high light conditions, and of late-successional species under low light conditions. Due to the interactive effects of tree species, light, CO2, and herbivory, community composition of forests may change in the future. [source] Trends in the consumption of antidepressants in Castilla y León (Spain).PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 9 2010Association between suicide rates, antidepressant drug consumption Abstract Objective To learn the evolution of antidepressant and lithium use in Castilla y León (Central Spain) and its relationship with suicide rates. Methods A search in the ECOM (Especialidades Consumo de Medicamentos) database of the Spanish Ministry of Health for antidepressants and lithium was carried out for the period 1992,2005. Defined daily doses (DDD) per 1000 inhabitants per day were obtained as consumption data. Population and suicide rates data come from the Spanish National Statistics Institute. Results Antidepressant consumption increased 7-fold, from 6.9 DDD per 1000 inhabitants per day in 1992 to 47.3 in 2005; the corresponding increase in cost was more than 10-fold. Selective serotonin reuptake inhibitors (SSRIs) comprised 77% of the total consumption. Venlafaxine consumption multiplied by 2.2. The consumption of monoamine oxidase inhibitors (MAOIs) decreased after venlafaxine and mirtazapine were marketed. Lithium consumption increased by 76% during the period studied, but it plateaued in 2000. Conclusions The consumption of antidepressants in Castilla y León has increased remarkably and the pattern has changed; there is an increase in the consumption of the new and more expensive antidepressants such as venlafaxine and escitalopram. No association was observed between suicide rates and antidepressant consumption. Copyright © 2010 John Wiley & Sons, Ltd.

Carrasco-Garrido PhD Abstract Purpose This study mainly aimed at describing the prevalence of psychotropic medication consumption in the Spanish elderly population between the years 1993 and 2003. Methods Descriptive, cross-sectional study covering the Spanish population aged 65 years and over, using data drawn from the 1993 and 2003 Spanish National Health Surveys (ENSS). A total of 9570 interviews were analysed (3436 from 1993 and 6134 from 2003). The independent variables were sociodemographic and health-related, and the dependent variable was total consumption of psychotropic medication. Using logistic multivariate regression models, we have analysed the temporal evolution of psychotropic medication consumption between 1993 and 2003. Results The prevalence of consumption was significantly higher in women (6.7% from 1993 and 26.4 % from 2003) versus men (2.4% from 1993 and 10.6% from 2003) (p,<,0.001). Multivariate analysis, highlighted the association between increased psychoactive drug intake and sex, nervous, depressive, sleep disorders and negative perception of health, displayed a strong association with consumption of psychoactive drugs across the 2 years. Conclusions In Spain, the prevalence of psychoactive drug consumption is higher among elderly women than men, and increases with negative perception of health. The prevalence of consumption was significantly higher in the year 2003. Copyright © 2006 John Wiley & Sons, Ltd. [source] Quantifying risks of volitional consumption of New Zealand Mudsnails by Steelhead and Rainbow TroutAQUACULTURE RESEARCH, Issue 4 2010Rolita Louise Bruce Abstract To assess the risk of transferring alien, invasive New Zealand mudsnails (NZMS) Potamopyrgus antipodarum with shipments of live rainbow or steelhead trout Oncorhynchus mykiss, we conducted laboratory trials to quantify and determine the volitional ingestion of snails from the bottom of laboratory tanks. Approximately, 2000 snails were placed on the bottom of a test tank and groups of 10 fish were added to each tank. After 48 h, the fish were removed, euthanized and the snails in the gastrointestinal tract were counted, and the proportion of snails remaining in each tank was measured. We found that both rainbow trout and steelhead consumed NZMS, but rainbow trout consumed nearly twice the number of snails that were consumed by steelhead trout. Feeding fish a maintenance diet increased the total consumption of snails by fish to an average of 64.5 snails per rainbow trout. Our study suggests that management strategies that depurate fish without feed for 48 h to reduce the risk of transfer of NZMS are not viable in preventing the transport of snails if rearing waters contain snails.
