Uso de pamidronato para o tratamento da osteoporose no sistema público de saúde no Brasil
Revista Brasileira de Reumatologia, 2017
The use of bisphosphonates for osteoporosis is effective in reducing the risk of fractures. However, oral formulations are sometimes not well tolerated or are contraindicated. Due to its availability in Brazilian public health system, pamidronate is frequently prescribed for osteoporosis, despite the lack of studies demonstrating its anti-fracture efficacy and the absence of FDA or EMEA approval for this purpose. The aim of this study was to evaluate the bone mineral density (BMD) response to pamidronate in a group of women with osteoporosis in a tertiary care hospital. Patients and methods: The medical records of women with osteoporosis who received pamidronate for up to two years of treatment were reviewed. Patients were stratified at high or intermediate risk of fracture. Results: A total of 70 women were in treatment with pamidronate. Among them, 74% were at high risk of fracture. A significant gain in spine BMD after 24 months of treatment was observed (p = 0.012). There was no difference between the groups of high and not high risk of fracture. At the femur, no significant increase in BMD was present, though, a strong negative correlation with high PTH levels (r = −0.61; p = 0.003) was seen. In the multivariate analysis BMI at 12 months had impact in the response to the treatment. Conclusion: The intravenous pamidronate in a group of postmenopausal women with predominant high risk of fracture promoted an isolated gain in the spine BMD, even though, clinical randomized trials are needed to confirm its anti-fracture efficacy.
Osteoporose: Atualização No Diagnóstico e Princípios Básicos Para O Tratamento
Revista Brasileira De Ortopedia, 2004
Osteoporosis is defined as a skeletal disease characterized by bone strength and quality compromise, leading to a higher risk of fractures. Hip fractures are the most serious and occur in later phases of the disease. Osteoporosis definition is also related to changes of bone densitometry values upon the loss of bone mass. Hence, the following terms are found: osteopenia when the loss goes from one to 2.5 standard deviations (SD), as identified by the exam; and osteoporosis, when the loss is above 2.5 standard deviations (SD). Bone mineral density reflects the mineral quantity quantified in a skeletal area, representing bony mineral density, expressed in grams by measured area or volume. Osteoporosis can be considered severe when, besides above-mentioned criterion, there is already a fracture. The osteoporosis can be idiopathic when, as such, the clinical condition will be named primary osteoporosis. Osteoporosis may also occur as a secondary disease process to a series of clinical

Risk factors for osteoporotic fractures and low bone density in pre and postmenopausal women Fatores de risco para fratura por osteoporose e baixa densidade óssea em mulheres na pré e pós-menopausa ABSTRACT OBJECTIVE: To estimate the prevalence and analyze risk factors associated to osteoporosis and low-trauma fracture in women. METHODS: Cross-sectional study including a total of 4,332 women older than 40 attending primary care services in the Greater São Paulo, Southeastern Brazil, between 2004 and 2007. Anthropometrical and gynecological data and information about lifestyle habits, previous fracture, medical history, food intake and physical activity were obtained through individual quantitative interviews. Low-trauma fracture was defi ned as that resulting from a fall from standing height or less in individuals 50 years or older. Multiple logistic regression models were designed having osteoporotic fracture and bone mineral density (BMD) as the dependent variables and all other parameters as the independent ones. The signifi cance level was set at p<0.05. RESULTS: The prevalence of osteoporosis and osteoporotic fractures was 33% and 11.5%, respectively. The main risk factors associated with low bone mass were age (OR=1.
Efeito do treinamento concorrente sobre a força e hipertrofia muscular de mulheres na pós-menopausa
Revista Brasileira de Atividade Física & Saúde, 2013
A associação do treinamento de força (TF) e aeróbio (TA), conhecido com treinamento concorrente (TC), parece diminuir os ganhos de força e hipertrofi a muscular quando comparado ao TF isolado. Dessa forma, esse estudo teve como objetivo comparar os efeitos de 16 semanas de TF e TC sobre os indicadores de hipertrofi a e a força muscular em mulheres de meia-idade na pós-menopausa. Participaram 24 mulheres, não ativas fi sicamente, subdivididas em três grupos: Grupo TC (n=8), Grupo TF (n=8) e Grupo Controle (n=8). Os treinamentos foram compostos de duas etapas (E1 e E2) com duração de oito semanas cada, e frequência de três sessões/semana (TF: 10 exercícios com 3 x 8-10 RM; TC: 6 exercícios com 3 x 8-10 RM, seguido de 30 min de caminhada ou corrida a 55-85% VO 2pico). Foram avaliadas a área muscular de coxa (AMC), força máxima e consumo pico de oxigênio (VO 2pico). Os resultados demonstraram aumento na força máxima nos exercícios leg press, supino reto e rosca direta para o TF e TC, sem diferença entre eles. Com relação aos indicadores hipertrófi cos não houve aumento na AMC para o TF e TC. Houve aumento do VO 2pico somente para o TC. Dessa forma, podemos concluir que o TC, realizado com as recomendações mínimas de TA preconizadas pelo American College of Sports Medicine (ACSM), não promoveu efeito de interferência na força máxima e hipertrofi a muscular de mulheres de meia-idade na pós-menopausa. Palavras-chave: Pós-menopausa; Composição corporal; Força muscular; Treinamento de força; Exercício. The combination of strength (TF) and aerobic training (TA), known as concurrent training (TC), seems to diminish the muscle strength and hypertrophy gains when compared with isolated TF. This study aimed to compare the eff ects of 16 weeks of concurrent training (TC) and resistance training (TF) on hypertrophic indicators and muscle strength of middleaged postmenopausal women. Participated 24 non-active women randomly assigned in three groups: TC (n=8), TP (n=8) and control group (GC, n=8). Both training protocols were divided in two phases lasting eight weeks with a three weeks sessions frequency (TF: 10 exercises, 3x8-10 RM; TC: 6 exercises, 3x8-10 RM followed by 30 min of walking or running at 55-85% VO 2peak). It were assessed thigh muscle area (AMC), muscle strength and maximal oxygen uptake (VO 2peak). Our data showed that both training protocols (i.e., TF and TC) signifi cantly increased maximal strength in leg press, bench press and arm curl without diff erences between groups. Regarding the hypertrophic indicators there was no diff erence in AMC for both training groups. VO 2peak signifi cantly increased only for TC. Thus, our data showed that when TC is held closely to the minimum of American College of Sports Medicine (ACSM) recommendation for aerobic training, no interference eff ect is observed in muscle strength and hypertrophic indicators in middle-aged postmenopausal women.

Osteoporosis, a metabolic disease characterized by low bone mass, deterioration of the bone tissue microarchitecture and increased susceptibility to fractures, is commonly regarded as a women's health problem. This point of view is based on the fact that compared with men, women have lower bone mineral density and longer lifespans and lose bone mass faster, especially after menopause, due to a marked decrease in serum estrogen levels. However, in the last 20 years, osteoporosis in men has become recognized as a public health problem due to the occurrence of an increasingly higher number of fragility fractures. Approximately 30% of all hip fractures occur in men. Recent studies show that the probability of fracture due to hip, vertebral or wrist fragility in Caucasian men older than fifty years, for the rest of their lives, is approximately 13% versus a 40% probability of fragility fractures in women. Men show bone mass loss and fractures later than women. Although older men have...
