TL;DR: Despite the consistency of the mechanistic approach in explaining the causal relation between hypertension and obesity, there is yet no evidence that one class of drug is superior to the others in controlling obesity–hypertension.
Abstract: Considerable evidence has suggested that excessive weight gain is the most common cause of arterial hypertension. This association has been observed in several populations, in different regions of the world. Obesity-hypertension, a term that underscores the link between these two deleterious conditions, is an important public health challenge, because of its high frequency and concomitant risk of cardiovascular and kidney diseases. The obesity-hypertension pandemic imposes a considerable economic burden on societies, directly reflecting on healthcare system costs. Increased renal sodium reabsorption and blood volume expansion are central features in the development of obesity-hypertension. Overweight is also associated with increased sympathetic activity. Leptin, a protein expressed in and secreted by adipocytes, is the main factor linking obesity, increased sympathetic nervous system activity and hypertension. The renin-angiotensin-aldosterone system has also been causally implicated in obesity-hypertension, because angiotensinogen is expressed in and secreted by adipose tissue. Hypoadiponectinemia, high circulating levels of free fatty acids and increased vascular production of endothelin-1 (ET-1) have been reported as potential mechanisms for obesity-hypertension. Lifestyle changes are effective in obesity-hypertension control, though pharmacological treatment is frequently necessary. Despite the consistency of the mechanistic approach in explaining the causal relation between hypertension and obesity, there is yet no evidence that one class of drug is superior to the others in controlling obesity-hypertension. In this review, we present the current knowledge and research in obesity-hypertension, exploring the epidemiologic evidence of the association, its probable pathophysiological mechanisms and treatment issues.

TL;DR: The paper discusses the social and the health consequences resulting from the expansion of the numbers of elderly people in Brazil over a short period, and an improvement in elderly people's health conditions and similar distribution of chronic diseases across all income groups is expressed.
Abstract: The paper discusses the social and, particularly, the health consequences resulting from the expansion of the numbers of elderly people in Brazil over a short period. The data used were from the 1998 and 2003 Pesquisa Nacional por Amostra de Domicilios (PNAD, the national household sampling survey), and they express an improvement in elderly people's health conditions and similar distribution of chronic diseases across all income groups. If, on the one hand, elderly people present greater disease burden and incapacities and they use healthcare services more, on the other hand, the current models for healthcare for the elderly are shown to be inefficient and high-cost. Creative and innovative structures are required, such as social centers with health assessments and treatment. Foremost on the agenda for Brazilian public policy, priority should be given to maintaining elderly people's functional capacity, with monitoring of their health conditions; preventive and differentiated actions relating to health and education; and qualified care and multidimensional comprehensive attendance.

TL;DR: The results suggest that parasites persist in the skin for many years despite treatment, and could have a role in the maintenance of immunologic memory in patients living in areas in which leishmaniasis is endemic.
Abstract: Leishmaniasis is an endemic disease in developing countries. The efficacy of therapy is usually evaluated through clinical parameters. To define the parasitologic cure, 20 patients were biopsied before and 1 month to 8 years after treatment. Paraffin-embedded tissue was used for DNA isolation. All patients had a positive polymerase chain reaction (PCR) result before therapy, except 1, for whom no histopathologic material was available. The causative agent was identified as belonging to the Leishmania (Viannia) subgenus by hybridization. Despite clinical healing and absence of reactivation or development of mucosal lesions, PCR was positive in scars of 16 patients (80%). The results suggest that parasites persist in the skin for many years despite treatment. Depending on specific pathogenetic features of the parasite and the immune status of the host, this phenomenon might result in mucosal lesions. Alternatively, it could have a role in the maintenance of immunologic memory in patients living in areas in which leishmaniasis is endemic.

TL;DR: The most important conclusion drawn from this symposium was that if the growing prevalence of overweight and obesity continues at this pace, the result will be a population of children and adolescents with metabolic syndrome, which would lead to high mortality rates in young adults, changing the current increasing trend of worldwide longevity.
Abstract: Overweight and obesity in youth is a worldwide public health problem. Overweight and obesity in childhood and adolescents have a substantial effect upon many systems, resulting in clinical conditions such as metabolic syndrome, early atherosclerosis, dyslipidemia, hypertension and type 2 diabetes (T2D). Obesity and the type of body fat distribution are still the core aspects of insulin resistance and seem to be the physiopathologic links common to metabolic syndrome, cardiovascular disease and T2D. The earlier the appearance of the clustering of risk factors and the higher the time of exposure, the greater will be the chance of developing coronary disease with a more severe endpoint. The age when the event may occur seems to be related to the presence and aggregation of risk factors throughout life. The treatment in this age-group is non pharmacological and aims at promoting changes in lifestyle. However, pharmacological treatments are indicated in special situations. The major goals in dietary treatments are not only limited to weight loss, but also to an improvement in the quality of life. Modification of risk factors associated to comorbidities, personal satisfaction of the child or adolescent and trying to establish healthy life habits from an early age are also important. There is a continuous debate on the best possible exercise to do, for children or adolescents, in order to lose weight. The prescription of physical activity to children and adolescents requires extensive integrated work among multidisciplinary teams, patients and their families, in order to reach therapeutic success. The most important conclusion drawn from this symposium was that if the growing prevalence of overweight and obesity continues at this pace, the result will be a population of children and adolescents with metabolic syndrome. This would lead to high mortality rates in young adults, changing the current increasing trend of worldwide longevity. Government actions and a better understanding of the causes of this problem must be implemented worldwide, by aiming at the prevention of obesity in children and adolescents.
