Raw and Processed Fruit and Vegetable Consumption and 10-Year Coronary Heart Disease Incidence in a Population-Based Cohort Study in the Netherlands

Background: Prospective cohort studies have shown that high fruit and vegetable consumption is inversely associated with coronary heart disease (CHD). Whether food processing affects this association is unknown. Therefore, we quantified the association of fruit and vegetable consumption with 10-year CHD incidence in a population-based study in the Netherlands and the effect of processing on these associations. Methods: Prospective population-based cohort study, including 20,069 men and women aged 20 to 65 years, enrolled between 1993 and 1997 and free of cardiovascular disease at baseline. Diet was assessed using a validated 178-item food frequency questionnaire. Hazard ratios (HR) were calculated for CHD incidence using multivariable Cox proportional hazards models. Results: During a mean follow-up time of 10.5y, 245 incident cases of CHD were documented, which comprised 211 nonfatal acute myocardial infarctions and 34 fatal CHD events. The risk of CHD incidence was 34 % lower for participants with a high intake of total fruit and vegetables (.475 g/d; HR: 0.66; 95 % CI: 0.45–0.99) compared to participants with a low total fruit and vegetable consumption (#241 g/d). Intake of raw fruit and vegetables (.262 g/d vs #92 g/d; HR: 0.70; 95 % CI: 0.47–1.04) as well as processed fruit and vegetables (.234 g/d vs #113 g/d; HR: 0.79; 95 % CI: 0.54–1.16) were inversely related with CHD incidence

The NASA Infrared Telescope Facility Comet Halley monitoring program 2: Post-perihelion results

The post perihelion results of a 1 to 20 micrometer infrared monitoring program of Comet Halley are presented. These results complement previous observations of the pre-perihelion passages of Halley. The observations cover the time period of Mar. 1986 to the present time. During the time the comet was observable, two or more observations were obtained per month. The most interesting results were: (1) a detectable change in the J-H and H-K colors of Halley, and (2) a search for a nucleus rotation at J during 20 Feb. to 10 Mar. was unsuccessful. The perihelion J-H and K-K colors were constant at 0.48 + or - 0.01 and 0.17, respectively. A preliminary reduction of the data is given. It is concluded that the colors were at first similar to pre-perihelion and then changed from July onward to be bluer and more similar to the solar colors. This suggests that a change may have occurred in the composition of the dust coma of Halley in July 1986

Can health care providers recognise a fibromyalgia personality?

OBJECTIVES: To determine if experienced health care providers (HCPs) can recognise patients with fibromyalgia (FM) based on a limited set of personality items, exploring the existence of a FM personality. METHODS: From the 240-item NEO-PI-R personality questionnaire, 8 HCPs from two different countries each selected 20 items they considered most discriminative of FM personality. Then, evaluating the scores on these items of 129 female patients with FM and 127 female controls, each HCP rated the probability of FM for each individual on a 0-10 scale. Personality characteristics (domains and facets) of selected items were determined. Scores of patients with FM and controls on the eight 20-item sets, and HCPs’ estimates of each individual’s probability of FM were analysed for their discriminative value. RESULTS: The eight 20-item sets discriminated for FM, with areas under the receiver operating characteristic curve ranging from 0.71-0.81. The estimated probabilities for FM showed, in general, percentages of correct classifications above 50%, with rising correct percentages for higher estimated probabilities. The most often chosen and discriminatory items were predominantly of the domain neuroticism (all with higher scores in FM), followed by some items of the facet trust (lower scores in FM). CONCLUSIONS: HCPs can, based on a limited set of items from a personality questionnaire, distinguish patients with FM from controls with a statistically significant probability. The HCPs’ expectation that personality in FM patients is associated with higher levels for aspects of neuroticism (proneness to psychological distress) and lower scores for aspects of trust, proved to be correct.info:eu-repo/semantics/publishedVersio

Emissões de Gases de Efeito Estufa da Rotação de Soja e Arroz Irrigado em Terras Baixas do Rio Grande do Sul.

A introdução da soja em rotação com o arroz irrigado constitui alternativa promissora para elevar a sustentabilidade dos sistemas de produção em terras baixas. Além dos benefícios inerentes à diversificação de culturas, por diminuir o período de tempo em que o solo é mantido inundado para o cultivo de arroz, pode influenciar no potencial de emissão de gases de efeito estufa (GEE) do sistema de produção. Este trabalho foi realizado com o objetivo de avaliar as emissões de metano (CH4) e óxido nitroso (N2O) e o potencial de aquecimento global (PAGp) de conformações da rotação soja/arroz irrigado em terras baixas do Rio Grande do Sul. O estudo foi realizado nas safras agrícolas 2019/2020 a 2021/2022, em Planossolo, em Capão do Leão RS. Avaliaram-se as conformações 2:1 (soja/soja/arroz e arroz/arroz/soja) e 1:1 (soja/arroz/soja e arroz/soja/arroz) da rotação soja/arroz irrigado. Para comparar o efeito das rotações de culturas sobre as emissões de GEE, consideraram-se os dados da safra 2021/2022, que retratam um ciclo completo das conformações 2:1 e 1:1. Comparou-se, ainda, a totalização das emissões sazonais de CH4 e N2O e do PAGp das conformações de rotações ao longo das três safras agrícolas. A rotação com soja reduziu as emissões de CH4 e aumentou as emissões de N2O do solo, sendo a redução das emissões de CH4 mais significativa que a elevação nas emissões de N2O. Esse efeito foi maior para a conformação soja-soja-arroz, relativamente à conformação arroz-soja-arroz. O CH4 contribuiu com quase a totalidade (>95%) do PAGp da cultura de arroz, enquanto que o N2O foi o componente principal do PAGp da soja (>90%). As conformações de rotação envolvendo dois cultivos sucessivos (30.231 kg CO2 eq.) ou intercalados de arroz irrigado (28.153 kg CO2 eq.) proporcionaram PAGp superiores àquelas com dois cultivos de soja, respectivamente, 10.436 e 11.772 kg CO2 eq., para soja/arroz/soja e soja/soja/arroz. A rotação do arroz irrigado com soja reduz o potencial de aquecimento global dos sistemas de produção em terras baixas, constituindo-se em estratégia mitigadora de emissões de gases de efeito estufa.ODS 13

High Diet Quality Is Associated with a Lower Risk of Cardiovascular Disease and All-Cause Mortality in Older Men

Although diet quality is implicated in cardiovascular disease (CVD) risk, few studies have investigated the relation between diet quality and the risks of CVD and mortality in older adults. This study examined the prospective associations between dietary scores and risk of CVD and all-cause mortality in older British men. A total of 3328 men (aged 60–79 y) from the British Regional Heart Study, free from CVD at baseline, were followed up for 11.3 y for CVD and mortality. Baseline food-frequency questionnaire data were used to generate 2 dietary scores: the Healthy Diet Indicator (HDI), based on WHO dietary guidelines, and the Elderly Dietary Index (EDI), based on a Mediterranean-style dietary intake, with higher scores indicating greater compliance with dietary recommendations. Cox proportional hazards regression analyses assessed associations between quartiles of HDI and EDI and risk of all-cause mortality, CVD mortality, CVD events, and coronary heart disease (CHD) events. During follow-up, 933 deaths, 327 CVD deaths, 582 CVD events, and 307 CHD events occurred. Men in the highest compared with the lowest EDI quartile had significantly lower risks of all-cause mortality (HR:0.75; 95% CI: 0.60, 0.94; P-trend = 0.03), CVD mortality (HR: 0.63; 95% CI: 0.42, 0.94; P-trend = 0.03), and CHD events(HR: 0.66; 95% CI: 0.45,0.97; P-trend = 0.05) but not CVD events (HR: 0.79; 95% CI: 0.60, 1.05;P-trend = 0.16) after adjustment for sociodemographic, behavioral, and cardiovascular risk factors. The HDI was not significantly associated with any of the outcomes. The EDI appears to be more useful than the HDI for assessing diet quality in relation to CVD and morality risk in older men. Encouraging older adults to adhere to the guidelines inherent in the EDI criteria may have public health benefit

An investigation of the phase locking index for measuring of interdependency of cortical source signals recorded in the EEG

The phase locking index (PLI) was introduced to quantify in a statistical sense the phase synchronization of two signals. It has been commonly used to process biosignals. In this article, we investigate the PLI for measuring the interdependency of cortical source signals (CSSs) recorded in the Electroencephalogram (EEG). To this end, we consider simple analytical models for the mapping of simulated CSSs into the EEG. For these models, the PLI is investigated analytically and through numerical simulations. An evaluation is made of the sensitivity of the PLI to the amount of crosstalk between the sources through biological tissues of the head. It is found that the PLI is a useful interdependency measure for CSSs, especially when the amount of crosstalk is small. Another common interdependency measure is the coherence. A direct comparison of both measures has not been made in the literature so far. We assess the performance of the PLI and coherence for estimation and detection purposes based on, respectively, a normalized variance and a novel statistical measure termed contrast. Based on these performance measures, it is found that the PLI is similar or better than the CM in most cases. This result is also confirmed through analysis of EEGs recorded from epileptic patients
