[Nutritional assessment at the time of hospital-admission: study initiation among different methodologies].

Background And Objectives: The elevated prevalence figures of hyponutrition in hospitalized patients--near 40%--is an issue of concern. This allows deducing that early identification of malnourished, or at risk for hyponutrition, patients by means of effective nutritional assessment methods may represent an essential tool for nutritional planning. The aim of this study was applying to a same group of patients different nutritional assessment methods (objective and subjective) at the time of hospital admission in order to assess the degree of effectiveness for its clinical application.

Prognostic significance of bundle-branch block in acute myocardial infarction: the importance of location and time of appearance.

Background: The presence of bundle-branch block (BBB) is associated with high mortality rates and is considered an important predictor of poor outcome in patients with acute myocardial infarction (AMI).

Hypothesis: The objective of this study was to assess the prognostic significance of BBB in patients with AMI depending on its form of presentation.

Methods: A multicenter prospective 1-year follow-up study involving 1,239 consecutive patients diagnosed with AMI was performed.

[Prognostic significance of advanced atrioventricular block in patients with acute myocardial infarction].

Background: Advanced atrioventricular block (AB) during acute myocardial infarction (AMI), characterizes a high-risk subgroup of patients. Our aim was to determine the prognostic significance of AB and its possible peculiarities in relation to infarction localization and/or the thrombolytic therapy.

Patients And Methods: The prospective study involved 1,239 patients with AMI.

Clinical and prognostic characteristics associated with age and gender in acute myocardial infarction: a multihospital perspective in the Murcia region of Spain.

Age and female gender have been associated with poor prognosis in acute myocardial infarction (AMI). Data currently available about the prognostic significance of gender in AMI might well have led to inappropriate/incomplete conclusions. A multicenter, prospective study on 1239 patients with AMI was conducted.

[Heart rate variability during the first 24 hours of acute myocardial infarction].

Background: To evaluate the heart rate variability (HRV) during the first 24 h after a myocardial infarction (MI), and to study its relationship with other clinical variables and in-hospital follow-up.

Patients And Methods: 101 patients (age < 80 years) with MI in sinus rhythm were prospectively studied. A Holter monitoring was performed during the first 24 h.

[Cholelithiasis and cancer: a study using precursor changes in a population with low incidence of cholelithiasis].

In order to assess the role of cholelithiasis in the pathogenesis of gallbladder carcinoma in a low-risk population for cholelithiasis and gallbladder cancer, we have studied the relationship between cholelithiasis and cancer. Our findings suggest that, both the relationship between cancer and cholelithiasis, and the frequency of precursors lesions, are very similar to those obtained in surveys carried out in high-risk populations for both conditions. Our findings bear out our hypothesis that cholelithiasis plays a main role in the pathogenesis of gallbladder carcinoma.

[Cholelithiasis in the region of Cartagena: an approximation to its real incidence based on the study of its symptomatic group].

We have studied the frequency of cholelithiasis in a group of patients who complained of clinical symptoms of cholelithiasis and lived in the region of Cartagena. This group of patients accounts for 40% of all the patients suffering from cholelithiasis this would account for 0.5% of the whole population and 1% of the exposed population over 30 year-of-age.
