Short-term inspiratory muscle training potentiates the benefits of aerobic and resistance training in patients undergoing CABG in phase II cardiac rehabilitation program / Treinamento muscular inspiratório de curto prazo potencializa os benefícios do treinamento aeróbico e resistido em pacientes após CRM na fase II de programa de reabilitação cardíaca

AbstractObjective:To investigate the efficiency of short-term inspiratory muscle training program associated with combined aerobic and resistance exercise on respiratory muscle strength, functional capacity and quality of life in patients who underwent coronary artery bypass and are in the phase II cardiac rehabilitation program.Methods:A prospective, quasi-experimental study with 24 patients who underwent coronary artery bypass and were randomly assigned to two groups in the Phase II cardiac rehabilitation program: inspiratory muscle training program associated with combined training (aerobic and resistance) group (GCR + IMT, n=12) and combined training with respiratory exercises group (GCR, n=12), over a period of 12 weeks, with two sessions per week. Before and after intervention, the following measurements were obtained: maximal inspiratory and expiratory pressures (PImax and PEmax), peak oxygen consumption (peak VO2) and quality of life scores. Data were compared between pre- and post-intervention at baseline and the variation between the pre- and post-phase II cardiac rehabilitation program using the Student's t-test, except the categorical variables, which were compared using the Chi-square test. Values of P<0.05 were considered statistically significant.Results:Compared to GCR, the GCR + IMT group showed larger increments in PImax (P<0.001), PEmax (P<0.001), peak VO2 (P<0.001) and quality of life scores (P<0.001).Conclusion:The present study demonstrated that the addition of inspiratory muscle training, even when applied for a short period, may potentiate the effects of combined aerobic and resistance training, becoming a simple and inexpensive strategy for patients who underwent coronary artery bypass and are in phase II cardiac rehabilitation.

ResumoObjetivo:Avaliar os efeitos de um programa de treinamento muscular inspiratório em curto prazo associado ao exercício aeróbio e resistido na força muscular respiratória, capacidade funcional e qualidade de vida de pacientes submetidos à cirurgia de revascularização do miocárdio, na Fase II da Reabilitação Cardíaca.Métodos:Trata-se de um estudo quase-experimental, prospectivo, com amostra de 24 pacientes submetidos à cirurgia de revascularização do miocárdio alocados aleatoriamente para Fase II da Reabilitação Cardíaca em dois grupos: grupo de treinamento muscular inspiratório associado ao treinamento combinado (aeróbio e resistido) (GRC + TMI, n=12) e grupo treinamento combinado e exercícios respiratórios (GRC, n=12) durante um período de 12 semanas, com 2 sessões semanais. Antes e após a intervenção, as seguintes mensurações foram obtidas: pressão inspiratória e expiratória máxima (PImáx e PEmáx), consumo de oxigênio de pico (VO2pico) e escore de qualidade de vida. Os dados foram comparados entre o momento pré e pós-intervenção na linha de base e a variação entre o pré e pós-programa de reabilitação cardíaca com uso do teste t de Student, exceto as variáveis categóricas, que foram comparadas pelo teste de qui-quadrado. Foi considerado um P<0,05.Resultados:Comparado ao GRC, o GRC + TMI apresentou maior incremento tanto na PImáx (P<0,001) quanto na PEmáx (P<0,001), no VO2pico (P<0,001) e na qualidade de vida (P<0,001).Conclusão:Demonstrou-se que a adição do programa de treinamento muscular inspiratório, mesmo quando aplicada por um curto período, pode complementar os efeitos do exercício aeróbio combinado ao resistido, tornando-se uma estratégia benéfica para pacientes submetidos à cirurgia de revascularização do miocárdio na Fase II da reabilitação cardíaca.

Visualization of the basement membrane zone of the bladder by optical coherence tomography: feasibility of noninvasive evaluation of tumor invasion.

OBJECTIVES: Imaging techniques with high resolution are evolving rapidly for medical applications and may substitute invasive diagnostic techniques. The use of ultrahigh resolution optical coherence tomography (UHR-OCT) to image healthy and morphologically altered bladder tissue with virtual histology is evaluated ex vivo to define parameters necessary for future, diagnostically relevant in vivo systems. Here, special focus is on the visualization of the basement membrane zone. METHODS: Optical coherence tomography examinations were performed by using a modified commercial OCT system comprising a Ti:sapphire femtosecond laser to support an enhanced resolution of 3 microm axial x 10 microm lateral. Tomograms of 142 fresh human bladder tissue samples from cystectomies, radical prostatectomies, and transurethral tumor resections were recorded and referenced to histologic sections using standard hematoxylin and eosin staining. RESULTS: OCT of normal bladder mucosa allows for a clear differentiation of urothelium and lamina propria. The basement membrane zone is identified as a narrow, low-scattering band between these layers. This allows for reliable exclusion of invasion. Healthy urothelial tissue, carcinoma in situ, and transitional cell carcinoma can be differentiated using this imaging technique. Sensitivity of UHR-OCT for malignant bladder tissue could be determined to be 83.8%, and specificity to be 78.1%. CONCLUSIONS: UHR-OCT is considered promising in the attempt to strive for fluorescence cystoscopy-guided virtual histology as a means of supporting therapeutic decisions for bladder neoplasia.

[Lifestyle drugs in medicine]. / Lifestyle-Medikamente in der Medizin.

Lifestyle drugs have become an important new group of medications, which are taken by healthy people to increase the individual well-being and quality of life. Nootropics, psychopharmaceuticals, hormones and "ecodrugs" are today the main groups. The wish for eternal youth, beauty and potency is central, and lifestyle medications are also requested to influence cosmetic findings, which are usually simply a result of the natural aging process. Lifestyle drugs seem to be harmless, but the physician must pay attention to possible abuse, side effects, risks and complications. Additionally, however, lifestyle drugs are also frequently used by patients suffering from emotional disorders such as somatoform disorders. Medicalization of physiological life is then expected to solve psychosocial problems, but without success. The use of lifestyle medications in somatoform disorders is contraindicated and psychotherapy or psychopharmacological treatment come first. With this overview article, we would like to make an update of new lifestyle drugs.
