[Birth, life, and death of a public policy: an ethnography of the Open Arms program].

Public policies for the crack cocaine scene known as Crackland (São Paulo, Brazil) have been implemented for decades, but there has been no comprehensive description of such policies. We conducted this study due to the importance and innovative nature of the Open Arms program, in order to provide a comprehensive picture of the program, from its beginning until it was closed down. The description involves: (i) a survey of the activities developed by public agents who preceded the program and who directly influenced its formulation; (ii) a description of the status of Crackland when Open Arms was launched; (iii) specification of the institutional actors and their respective roles; and (iv) an explanation of the main events marking this public policy's development until its extinction.

Chemical Methods for Cleaning Conventional Dentures: What is the Best Antimicrobial Option? An In Vitro Study.

Purpose: To investigate the antimicrobial efficacy of different chemical agents used for denture cleaning.

Materials And Methods: Biofilm samples collected from 10 removable dentures were subjected to 10 disinfection protocols: distilled water for 30 min (negative control); 1% sodium hypochlorite for 10 min (positive control); diluted sodium hypochlorite for 10 min; vinegar for 20 min; 0.2% peracetic acid for 5 min; alkaline peroxide solution for 5 min; alkaline peroxide solution for 30 min; 0.

Abnormal heart rate recovery and deficient chronotropic response after submaximal exercise in young Marfan syndrome patients.

Background: Marfan syndrome patients present important cardiac structural changes, ventricular dysfunction, and electrocardiographic changes. An abnormal heart rate response during or after exercise is an independent predictor of mortality and autonomic dysfunction. The aim of the present study was to compare heart rate recovery and chronotropic response obtained by cardiac reserve in patients with Marfan syndrome subjected to submaximal exercise.

The dysfunction of ammonia in heart failure increases with an increase in the intensity of resistance exercise, even with the use of appropriate drug therapy.

Background: Hyperammonemia during rest periods is a dysfunction in heart failure (HF). The low formation of ammonia during exercise reflects an inefficiency of purine metabolism. Hyperkalemia in response to physical exercise is common in HF and may contribute to a contractile inefficiency in type II fibers, leading to early fatigue.

Effect of a physical exercise program in a patient with Marfan syndrome and ventricular dysfunction.

Marfan syndrome (MS) is an autosomal dominant disorder that affects multiple organs and systems. Several cardiac alterations are present, with the main ones being aortic root and ascending aorta dilatation, mitral valve prolapse and left ventricle (LV) dilatation. Aerobic exercise has not shown to be a non-drug therapy that promotes anti-remodeling effect in patients with heart failure.

Anthropometric and musculoskeletal assessment of patients with Marfan syndrome.

Background: Marfan syndrome (MS) is an autosomic dominant condition of the connective tissue that involves the ocular, cardiovascular and musculoskeletal systems. MS is caused by mutations in the fibrillin-1 gene, leading to joint ligaments flaccidity, joint hypermobility and an overgrowth of the long bones.

Objectives: The aim of the present study was to assess anthropometry, musculoskeletal alterations and the prevalence of physical therapy treatments among patients with MS.

In vitro antifungal action of different substances over microwaved-cured acrylic resins.

Objective: The presence of Candida albicans on the surfaces of denture-base acrylic resins is strongly related to the development of oral stomatitis. This study evaluated the antifungal action of different agents over microwave-cured acrylic resin without polishing specimens previously contaminated with Candida albicans.

Material And Methods: Sixty specimens were immersed in BHI broth previously inoculated with the yeast and stored for 3 h at 37 degrees C.

[Different patterns for the 6-minute walk test as a test to measure exercise ability in elderly with and without clinically evident cardiopathy].

Objectives: Evaluate the correlation between peak oxygen consumption (VO2peak), from cardiopulmonary test with the distance covered in the six-minute walk test (6MWT) in healthy elderly and with myocardial infarction (MI).

Methods: Thirty individuals were studied, with age range 65-87 years (76.03 +/- 4.
