Furthermore, population ageing plus recent increases in obesity and diabetes may soon increase total CHD deaths. Predictions of future CHD mortality are thus potentially problematic. Here we explore future projections of CHD mortality in England & Wales under two conventional but dramatically contrasting assumptions. Materials and Methods: In SCENARIO A, we used a conventional counterfactual, assuming that the last-observed CHD mortality rates (ONS) from 2011 would persist unchanged to 2030.The future number of deaths was then calculated by applying those rates onto 2012-2030 population estimates. In SCENARIO B, we assumed that the recent trend in CHD mortality rates would continue. We used a well-established hierarchical Bayesian Age Period Cohort (BAPC) model, which works under the assumption that variability i...

Although CHD death rates are falling, a large proportion of hypertensive patients are poorly controlled and population salt intake, a major determinant of hypertension, remains well above the recommended daily maximum of 6g/day. G. Rose identified two strategies to reduce CHD mortality. The first proposes that small, but population-wide, reductions in systolic blood pressure (SBP), achieved by public health measures to reduce salt intake, will deliver large reductions in mortality. The second seeks to reduce mortality by treating hypertensive patients and keeping them below a given risk-threshold. Here we explore the potential to reduce CHD deaths through a combination of these strategies in England and Wales up to 2030. Methods: We used the Stock of Health (SoH) model assuming each individual is born with a SoH, and on an annual basis this stock depreciates due to demographic f...

Objective: To demonstrate in Wistar rats fed with high-fat diet if the administration of synthetic peptides corresponding to the 116-130 peptide of mouse leptin (SR 116), its human homologue peptide (SH 95: sequence 95-109 from the 1AX8 protein) and five modified peptides (P80 to P84) similar to these two peptides, produces effects related to regulation of body fat. Materials and methods: Nine-week old Wistar rats were fed a high-fat diet for fifteen weeks. On the fifteenth week, and for five consecutive days, they were treated with the peptides to be evaluated. During the days of treatment, body weight and food intake were evaluated. After the last peptide administration, lipid profile, glycerol in the cellular medium, and DNA fragmentation in adipocytes...

Yet predictions of future CHD mortality are potentially problematic due to population ageing and increase in obesity and diabetes. Here we explore future projections of CHD mortality in England & Wales under two contrasting future trend assumptions. Methods: In scenario A, we used the conventional counterfactual scenario that the last-observed CHD mortality rates from 2011 would persist unchanged to 2030. The future number of deaths was calculated by applying those rates to the 2012-2030 population estimates. In scenario B, we assumed that the recent falling trend in CHD mortality rates would continue. Using Lee-Carter and Bayesian Age Period Cohort (BAPC) models, we projected the linear trends up to 2030. We validate our methods using past data to predict mortality from 2002-2011. Then, we computed the error between observed and projected values. Results: In scenario A, assuming that 2011 mortality rates stayed constant by 2030, the number of CHD deaths would increase 62% or approximately 39,600 additional deaths. In scenario B, assuming recent declines continued, the BAPC model (the model with lowest error) suggests the number of deaths will decrease by 56%, representing approximately 36,200 fewer deaths by 2030. Conclusions: The decline in CHD mortality has been reasonably continuous since 1979, and there is little reason to believe it will soon halt. The commonly used assumption that mortality will remain constant from 2011 therefore appears slightly dubious. By contrast, using the BAPC model and assuming continuing mortality falls offers a more plausible prediction of future trends. Thus, despite population ageing, the number of CHD deaths might halve again between 2011 and 2030. This has implications for how the potential benefits of future cardiovascular strategies might best be calculated and presented.

The study was based on the theoretical concepts of self-esteem, perceived self-efficacy and consumption of alcohol and tobacco. The design was descriptive and correlational with a sample of 359 students. A substantial difference was found in the consumption of tobacco among secondary students from urban and rural areas (U= 7513.50, p = .03). The average consumption in urban area was higher (average chi = .35) than in the rural area (average chi = .14). A negative and significant relation was found between the quantity of drinks consumed on a typical day and self-esteem (r s = - .23, p <.001), as well as for the quantity of cigarettes consumed on...

In the southern municipalities of San Esteban and Guanaco, approximately 150 km from the Atlantic coast, substantial numbers of coyol palm (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) and several coconut palms growing nearby were either dead or in an advanced stage of decline during 2005. Declining palms of both species exhibited loss of fruit, withered inflorescences, and dried, discolored (grayish brown) leaves. Most or all leaves on declining palms had collapsed and hung downward around the stem. Samples (3 to 5 g) of tissue were excised from stems of 20 coyol and 2 coconut palms. DNA was extracted from each sample using a previously described protocol (2) and assayed for phytoplasma DNA using polymerase chain reaction (PCR) employing phytoplasma universal rRNA primer pair P1 (1) and P7 (4).

Juveniles of Pheromermis sp. (Mermithidae) were found coiled inside stonefly nymphs collected at seven sites in the Guare and Emilia rivers in northern Venezuela. Prevalence in Anacroneuria blanca was 93.2% () and in A. caraca was 91.5% (). In A. blanca, a higher number of juveniles per individual host was observed than in A. caraca, a fact that is probably related to body size. Although parasites were observed in all body regions, the highest incidence occurred in the legs and thorax. Considering the nematode prevalence and intensity of parasitism, we consider individuals of Anacroneuria spp. to be important hosts of Pheromermis in these rivers.

We aimed to estimate the potential reduction in coronary heart disease (CHD) deaths. Methods and Results— We used data on 40 373 adults free of cardiovascular disease from the National Health and Nutrition Examination Survey (NHANES; 1988–2010). We quantified recent trends for 6 metrics (total cholesterol, systolic blood pressure, physical inactivity, smoking, diabetes mellitus, and obesity) and generated linear projections to 2020. We projected the expected number of CHD deaths in 2020 if 2006 age- and sex-specific CHD death rates remained constant, which would result in ≈480 000 CHD deaths in 2020 (12% increase). We used the previously validated IMPACT CHD model to project numbers of CHD deaths in 2020 under 2 different scenarios: (1) Assuming a 20% improvement in each cardiovascular health metric, we project 365 000 CHD deaths in 2020 (...

Se determino que las ninfas de ambas especies se alimentan de estadios inmaduros de insectos de las familias Simuliidae y Baetidae. Se observaron individuos con caracteres morfologicos compartidos, lo cual esta probablemente relacionado con el requerimiento ecologico similar de ambas especies de Anacroneuria, debido a su condicion de simpatria.
