Análise de dados colhidos a bordo da embarcação Cassiopeia de 7 a 15 de Maio de 1999

This paper aims to analyse the results of a cruise aboard the vessel Cassiopeia, held from 7 to 15 May 1999. These results relate mainly to the Quissico area and have as an objective to verify different features: total fish catch, predominance of caught species, dimensions of captured fish and fishing effort

The Accuracy of the Electrocardiogram during Exercise Stress Test Based on Heart Size

BACKGROUND: Multiple studies have shown that the exercise electrocardiogram (ECG) is less accurate for predicting ischemia, especially in women, and there is additional evidence to suggest that heart size may affect its diagnostic accuracy. HYPOTHESIS: The purpose of this investigation was to assess the diagnostic accuracy of the exercise ECG based on heart size. METHODS: We evaluated 1,011 consecutive patients who were referred for an exercise nuclear stress test. Patients were divided into two groups: small heart size defined as left ventricular end diastolic volume (LVEDV) <65 mL (Group A) and normal heart size defined as LVEDV ≥65 mL (Group B) and associations between ECG outcome (false positive vs. no false positive) and heart size (small vs. normal) were analyzed using the Chi square test for independence, with a Yates continuity correction. LVEDV calculations were performed via a computer-processing algorithm. SPECT myocardial perfusion imaging was used as the gold standard for the presence of coronary artery disease (CAD). RESULTS: Small heart size was found in 142 patients, 123 female and 19 male patients. There was a significant association between ECG outcome and heart size (χ(2) = 4.7, p = 0.03), where smaller hearts were associated with a significantly greater number of false positives. CONCLUSIONS: This study suggests a possible explanation for the poor diagnostic accuracy of exercise stress testing, especially in women, as the overwhelming majority of patients with small heart size were women

Heritability and Predicted Gain of Twelve Traits in Fifty-five Upland Rice Varieties

The genetic information about upland rice traits in terms of heritability (H2b) and predicted gain expressed to the mean (RAM) could lead to an effective selection process in the upland varietal development. Fifty-five upland rice varieties (URVs) were evaluated using 12 traits in three seasons. Traits culm length (CL), days to 50% flowering (DF), days to maturity (DM), flag leaf length (FLL), flag leaf width (FLW), grain length (GL), grain width (GW), one thousand grain weight (OTGW), plant height (PH), panicle length (PL), productive tillers (PT) and yield (YCC) had an overall mean of 102.7 cm, 55.3 days, 91.2 days, 37.9 cm, 1.6 cm, 8.69 mm, 2.92 mm, 21.2 g, 120.6 cm, 26.5 cm, 6.7 tillers and 2.25 t/ha, respectively. STAR V2.01 provided a combined analysis of variance (ANOVA) and found a high significance among URVs in all traits with corresponding coefficient of variation range of 3.3% (DM) to 24.16% (YCC). H2b on the other hand had a range of 89.3% (PH) to 99.2% (OTGW) while RAM had a range of 14.5% (GL) to 91.7% (YCC). It was CL, DF, DM, FLL, GL, OTGW, PH, PL and YCC with H2b &gt;95% were highly heritable and FLL, FLW, PL and YCC with RAM &gt;30% were high in genetic gain. Therefore, bigger flag leaves (FLL and FLW) as first indicator and yield as last indicator could be recommended in deciding what genotypes to keep and develop in the upland breeding process

Anemia in elderly patients ≥65 years of age: a hospital-based cross-sectional study

Introduction: Anemia in elderly patients of any degree contributes significantly to morbidity and mortality and has a significant effect on the quality of life. Despite of high prevalence, very few studies have examined the effect of anemia in elderly patients in India. Hence, this study is undertaken to know the prevalence and clinicopathological pattern of anemia in elderly patients. Objectives: 1. To estimate the prevalence of anemia in the elderly aged 65 years and above. 2. To determine the severity, clinicohematological patterns, and causes of anemia in the elderly aged 65 years and above. Materials and Methods: A hospital-based descriptive cross-sectional study was done. The study was conducted for 1 year; during this period, elderly patients aged 65 years and above admitted for other medical conditions were recruited in the study using consecutive sampling technique until the desired sample size of 236 was achieved and they were evaluated for anemia. Among them with hemoglobin cutoff value <13 g% for men, <12 g% for women were further evaluated to known the cause of anemia and its clinicohematological pattern. Ethical committee approval was obtained. Data were analyzed using SPSS Software version 23.0. Results: The mean age of the participants was 73.9 ± 7.4 (standard deviation [SD]) years. Majority, 53.8%, of the participants were males. Among the 236 elderly patients, recruited in the study 65.3% were anemic and among them 44.2 had mild anemia and 37% had moderate anemia. Mean hemoglobin value of the participants was 10.7 ± 2.83 SD and it ranged from 3 to 16.3 g/dl. There was no significant difference in the hematological parameters between male and female elderly patients in the study. The main cause of anemia was found to be due to chronic diseases followed by iron-deficiency anemia. Conclusion: This study concludes that anemia was highly prevalent among elderly patients and most of them had identifiable and treatable etiology. Hence, all elderly patients with anemia should be evaluated properly for underlying etiology and treated accordingly to reduce the mortality and morbidity in elderly patients with multiple comorbidities

Impact of Mobile Phones on Staple Food Markets in Mozambique: Improved Arbitrage or Increased Rent Extraction?

I use the quasi experimental nature of the roll-out of the mobile phone network in Mozambique to estimate the impact of search costs on the dispersion of maize prices and transport costs. The introduction of mobile phone services from 1997 to 2009 explains a 4.5-11% percent reduction in price dispersion of maize prices, and a slightly larger reduction in per ton km transport costs. Apart from an improvement of the efficiency of maize markets, the evidence suggests that traders benefit by capturing increased rent income. Various sources of potential heterogeneity are identified: the reduction is larger for pairs connecting remote locations, for source markets with a low poverty head count and with a higher mobile phone coverage in neighbouring markets, and during drought periods
