The purposes of this study were to compare the hypotensive effects of treadmill running (TR) and resistance exercise (RE) performed by hypertensive subjects and to verify if the hypotensive effects of these exercises are maintained during a regular white-collar workday. Fifteen white-collar workers (42.9 +/- 1.6 years), treated with antihypertensive medication, accomplished three different sessions: 20 minutes of TR (approximately 70-80% of heart rate reserve), 20 minutes of circuit training RE (20 repetitions at 40% of 1 repetition maximum), and a control session without exercise (CON). The systolic blood pressure (BP), diastolic BP, heart rate, and blood lactate were measured at resting (Rest) and after sessions at 15th (R15), 30th (R30), 45th (R45), and 60th (R60) min, as well as after lunch (AL), four (R4h) and seven (R7h) hours of recovery at the participants' workplace. In relation to rest, a higher decrease of systolic BP after TR (-11.1 +/- 7.6 mm Hg) and RE (-12.6 +/- 7.3 mm Hg) was observed respectively at the R30 and R45. For diastolic BP, the highest decreases after TR (-4.0 +/- 6.4 mm Hg) and RE (-9.0 +/- 7.0 mm Hg) were observed respectively at the R45 and R30. The systolic BP and mean BP after TR and RE differed significantly from CON session (p < 0.05), and lower post-exercise values could be observed over the workday. In conclusion, both 20 minutes of TR and RE resulted in postexercise hypotension, and were able to reduce BP throughout 7 hours after exercise, even throughout the subject's regular occupational activities. Also, the RE promoted higher cardiac protection and can be a useful model of physical exercise prescription for hypertension individuals.

We evaluated the impact of long-term exercise on telomere dynamics in wild-derived short telomere mice (CAST/Ei) over 1 year. We observed significant telomere shortening in liver and cardiac tissues in sedentary 1-year-old mice compared with young (8 weeks) baseline mice that were attenuated in exercised 1-year-old animals. In contrast, skeletal muscle exhibited significant telomere shortening in exercise mice compared with sedentary and young mice. Telomerase enzyme activity was increased in skeletal muscle of exercise compared with sedentary animals but was similar in cardiac and liver tissues. We observed significant age-related decreases in expression of telomere-related genes that were attenuated by exercise in cardiac and skeletal muscle but not liver. Protein content of TRF1 was significantly increased in plantaris muscle with age. In summary, long-term exercise altered telomere dynamics, slowing age-related decreases in telomere length in cardiac and liver tissue but contributing to shortening in exercised skeletal muscle.

The purpose of this study was to compare different methods to identify the lactate threshold (LT) and glucose threshold (GT) on resistance exercise for individuals with type 2 diabetes. Nine men with type 2 diabetes (47.2 +/- 12.4 years, 87.6 +/- 20.0 kg, 174.9 +/- 5.9 cm, and 22.4 +/- 7.2% body fat) performed incremental tests (ITs) on the leg press (LP) and bench press (BP) at relative intensities of 10, 20, 25, 30, 35, 40, 50, 60, 70, 80, and 90% of one-repetition maximum (1RM) at each 1-minute stage. During the 2-minute interval between stages, 25 mul of capillary blood were collected from the earlobe for blood lactate [Lac] and blood glucose [Gluc] analysis (YSI 2700S). The LT in the LP and BP was identified at IT by the inflexion in [Lac] response as well as by an equation originated from a polynomial adjustment (LTp) of the [Lac]/% 1RM ratio responses. The lowest [Gluc] during the IT identified the GT. The analysis of variance did not show differences among the 1RM at the thresholds identified by different methods in the LP (LTLP = 31.0% +/- 5.3% 1RM; GTLP = 32.1% +/- 6.1% 1RM; LTpLP = 36.7% +/- 5.6% 1RM; p > 0.05) and BP (LTBP = 29.9% +/- 8.5% 1RM; GTBP = 32.1% +/- 8.5% 1RM; LTpBP = 31.8% +/- 6.7% 1RM; p > 0.05). It was concluded that it was possible to identify the LT and GT in resistance exercise by different methods for individuals with type 2 diabetes with no differences between them. The intensities (kg) corresponding to these thresholds were between 46% and 60% of the body weight on the LP and between 18% and 26% of the body weight on the BP, in which the exercise prescription would be done to this intensity in 3 sets of 20 to 30 repetitions each and 1 minute of rest while alternating the muscle groups for blood glucose control for individuals with characteristics similar to the participants.

Objective: To evaluate the frailty syndrome in the elderly nursing diagnosis in elderly with chronic diseases of a health district of the Federal District. Method: A quantitative, descriptive, cross-sectional study was conducted with elderly patients served at the Basic Health Units, who presented arterial hypertension and/or diabetes mellitus. The following were used: a sociodemographic questionnaire, the Mini-Mental State Examination, anthropometric data, evaluation of sarcopenia (measured by body composition), muscle strength and functional capacity, and the identification of NANDA-I nursing diagnosis. A statistical software was used for data analysis. Results: Participation of 78 elderly people, of which 93.6% of had Impaired memory, 93.6% had Impaired physical mobility, 82.1% had Fatigue, 76.9% had Impaired ambulation, 53.8% had Dressing self-care deficit, 43.6% had Activity Intolerance, 35.9% had Social Isolation, 30.8% had Hopelessness, 29.5% had Feeding self-care deficit, 29.5% had Bathing self-care deficit, 12.8% had Toileting self-care deficit, and 10.3% had Decreased cardiac output. Conclusion: The nursing diagnosis Frailty Syndrome in the Elderly allows a multidimensional view of the elderly. Since one factor can cause health problems in several health fields, nurses must intervene early, plan and implement actions in the short and long term.

Este estudo teve como objetivo avaliar a qualidade de vida (QV) de cardiopatas pós-implante de marcapasso (MP) de uma cidade no interior de Goiás / Brasil. Estudo de intervenção tipo antes e depois. Vinte e três pacientes portadores de MP cardíaco foram avaliados antes e após implante de MP. Os instrumentos utilizados foram o AQUAREL associado ao SF-36. Houve predomínio de indivíduos do sexo feminino (65%), com idade média de 64,9 anos, e baixa escolaridade (43%). Os domínios que evidenciaram melhor QV, através do instrumento AQUAREL, foram desconforto no peito (M=71,60) e arritmia (M=70,87) e menor para dispneia ao exercício (M=61,81). Na comparação de QV antes e após o implante de MP, observou-se melhora significativa nos domínios do SF-36: capacidade funcional, dor, estado geral de saúde, aspecto social e aspecto emocional. De forma geral, os resultados do SF-36 indicam que houve melhora da qualidade de vida após implante de MP. Descritores: Qualidade de Vida; Marca-Passo Artificial; Estimulação Cardíaca Artificial; Avaliação em Enfermagem.

RESUMO ABSTRACT Sectional study of multiple cases involving 30 patients after heart catheterization aiming to establish the nursing diagnoses according to the North American Nursing Diagnoses Association (NANDA). The method of data collection was the Nursing Process based on the INTRODUÇÃOAs cardiopatias são patologias crônico-degenerativas, de alta incidência no Brasil e no mundo, que podem acometer seres humanos de qualquer faixa etária.Atualmente no Brasil, a taxa de mortalidade em decorrência das doenças infecciosas diminuiu, sendo que cerca de 32% dos óbitos registrados em todas as regiões do país são atribuídos às patologias cardiovasculares (1) . A revascularização do miocárdio tem sido indicada nas coronariopatias de isquemia acentuada.
