The influence of extreme body weight on clinical outcome of patients with venous thromboembolism: findings from a prospective registry (RIETE). Summary. Background: Data evaluating the safety of using weight-based dosing of low-molecular-weight heparin (LMWH) in either underweight or obese patients with venous thromboembolism (VTE) are limited. Thus, recommendations based on evidence from clinical trials might not be suitable for patients with extreme body weight. Patients and Methods: Patients with objectively confirmed, symptomatic acute VTE are consecutively enrolled into the Registro Informatizado de la Enfermedad TromboEmbo´lica (RIETE) registry. For this analysis, data from patients in the following ranges of body weight were examined: <50, 50-100, and >100 kg. Patient characteristics, underlying conditions, treatment schedules and clinical outcomes during the first 15 days of treatment were compared. Results: As of August 2004, 8845 patients with acute VTE were enrolled from 94 participating centers. Of these, 169 (1.9%) weighed <50 kg, 8382 (95%) weighed 50-100 kg and 294 (3.3%) weighed >100 kg. Patients weighing <50 kg were more commonly females, were taking non-steriodal antiinflammatory drugs (NSAIDs), and had severe underlying diseases more often than patients weighing 50-100 kg. Their incidence of overall bleeding complications was significantly higher than in patients weighing 50-100 kg (odds ratio 2.2; 95% CI: 1.2-4.0). Patients weighing >100 kg were younger, most commonly males, and had cancer less often than those weighing 50-100 kg. Incidences of recurrent VTE, fatal pulmonary embolism or major bleeding complications were similar in both groups. Conclusions: Patients with VTE weighing <50 kg have a significantly higher rate of bleeding complications. The clinical outcome of patients weighing over 100 kg was not significantly different from that in patients weighing 50-100 kg.

Obesity in patients hospitalised for COPD substantially reduces in-hospital mortality risk and the possibility of early re-admittance. Malnutrition is associated with an important increase in in-hospital mortality and risk of re-admittance in the 30 days following discharge.

The management of patients admitted during weekends may be compromised because the level of staffing in the hospital is often lower then. This study was conducted to assess what independent influence, if any, weekend admission might have on inhospital mortality. The authors analyzed the clinical data of 429,880 adults >14 years of age who were admitted to internal medicine wards in Spain after having presented to the hospitals' emergency departments. Overall mortality and early mortality (occurring in the first 48 hours) were examined, taking into account whether a patient was admitted on a weekend or a weekday, in addition to other parameters. Weekend admissions were associated with a significantly higher inhospital mortality than weekday admissions among patients admitted to an internal medicine service (odds ratio [OR] = 1.1; 95% confidence interval [CI] = 1.14-1.08). Differences in mortality persisted after adjustment for age, sex, and coexisting disorders (OR = 1.071; 95% CI = 1.046-1.097). Analyses of deaths within 2 days after admission showed larger relative differences in mortality between weekend and weekday admissions (OR = 1.28; 95% CI = 1.22-1.33). For patients admitted to an internal medicine service via an acute care visit to the emergency room, admission on weekends is associated with higher mortality than admission during the week.

Lercanidipine showed a high antihypertensive effect in CRF patients. It has a good tolerability profile and showed an interesting effect on plasmatic lipids. An improvement in renal function, measured through creatine clearance, was detected.
