Position of the international forum of internal medicine on habits, lifestyle changes and a healthy environment for the prevention of cardiovascular diseases

Cardiovascular diseases (CVD), mainly ischemic heart disease and stroke, is the main cause of death worldwide and each year more people die from CVD than from any other cause. These data call for a paradigm shift, where health promotion and cardiovascular prevention will acquire a central role in health policies. From this perspective, dedicating time during the consultation to promoting the acquisition of heart-healthy habits would be indicated in all individuals, regardless of cardiovascular risk classification, the role of the internist being fundamental. This position document from the International Forum of Internal Medicine (FIMI) presents the main indications regarding changes in lifestyle and acquisition of healthy habits to prevent CVD. The different sections will address topics including: nutrition, physical activity, sedentary lifestyle, obesity, smoking, alcohol consumption, sleep, stress, environmental problems related to CVD and specific conditions in women. A section is included about starting CVD promotion and prevention measures at an early age, childhood and adolescence, also mentioning epigenetic aspects related to CVD. Social determinants in CVD are also taken into account, since some of these aspects, such as low socioeconomic level, modify cardiovascular risk and should be taken into account.

Beta-adrenergic control of the water permeability of the skin during rehydration in the toad Bufo arenarum

1. Toads dehydrated to 80% of their standard weight (% SW) were rehydrated during 3 hr in distilled water. 2. Water permeability of the skin was positively correlated with the degree of dehydration in the range 80-100% SW. 3. Systemic administration of the beta-adrenergic agonist isoproterenol (5 mg/kg) 90 min after rehydration started (animals fully hydrated) increased skin permeability to the values observed in 80% SW dehydrated animals. 4. The administration of the beta-adrenergic blocker propranolol (5 mg/kg) 15 min before rehydration started produced a long-lasting decrease in water permeability during the 3 hr of rehydration. 5. The results are consistent with the hypothesis of a beta-adrenergic control of the water permeability of the skin during rehydration.

Morphological characterization of the Serratia marcescens bacteriophage SLP

SLP is a lambda-like bacteriophage specific for Serratia marcescens strains. Morphological studies have demonstrated that SLP virions present two cross-bar structures on its tail not described in bacteriophages specific for Enterobacteriaceae. SDS-polyacrylamide gel electrophoresis of major capsid proteins as well as electron micrographs are reported.
