RESUMO
BACKGROUND: Older people including ex-servicemen (ESM) in India are left to fend for themselves due to nuclear family system. Most children are not staying with them due to reasons such as acquiring of education or employment at distant places. These factors, coupled with deteriorating health with advancing age, change in value system and attitude amongst children who give more importance to materialism, it was felt necessary to find modalities to empower and strengthen ESM by available methods of including progressive weight training, yoga and meditation. METHODS: An interventional "Before and After" study was planned for a period of three months for in-patient ESM of a military hospital for common lifestyle diseases namely stroke, diabetes, senile depression, acute myocardial infarction and hypertension. Data of anthropometry, laboratory investigations and Hamilton rating scale for depression (HRSD) were taken before the study. These cases were then subjected to interventions (progressive weight training and spiritual health enhancement by yoga with meditation for three months) followed by same measurements again. RESULT: Statistically significant differences were observed before and after study with respect to pulse, respiratory rate, blood pressure, blood glucose, total cholesterol, low density lipoproteins (LDL), very low density lipoproteins (VLDL) and Hamilton depression score (p<0.05). The sleep pattern, sense of well being and posture while sitting to standing and walking with degree of support (stick/other person's help) improved considerably after the interventions. CONCLUSION: ESM are recommended to be trained much before retirement on progressive weight training and yoga in regimental centre/station institute. Provision to be made in existing ex-servicemen contributory health scheme (ECHS) polyclinics for employment of part time trainers for weight training and yoga. The physical and spiritual strengthening results in better capability to deal with old age and its problems.
RESUMO
CONTEXT: Dysregulated cell proliferation caused by inhibitors of programmed cell death (apoptosis) contributes to tumor progression and spread. Aberrant expression of Bcl-2, the most notable inhibitor of apoptosis, has been well characterized in several human malignancies. Recent studies have described a novel apoptosis inhibitor, survivin, in human carcinomas, although its exact role remains to be characterized. OBJECTIVE: The purpose of this study was to evaluate the immunohistochemical expression of Bcl-2 and survivin proteins in prostate cancer and to correlate the results with clinicopathologic variables. DESIGN: Formalin-fixed, paraffin-embedded tissue sections from 138 cases of prostatic adenocarcinomas (PACs) were immunostained by an automated method using specific antibodies against survivin and Bcl-2. Staining was semiquantitatively scored based on both intensity and distribution, and results were correlated with morphologic and prognostic variables. RESULTS: Of the 138 PACs tested, 113 (82%) expressed survivin. We found no correlation between survivin expression and prognostic variables, including grade, stage, DNA content (ploidy), and recurrence. Bcl-2 expression was positive in 95 (69%) of these 138 cases and correlated with nondiploid DNA content. Fourteen (50%) of 28 nondiploid PACs expressed Bcl-2, compared to 17 (25%) of 68 diploid tumors (P =.02). A trend for association of Bcl-2 expression with tumor stage was noted as follows: 21 (39%) of 54 advanced-stage PACs expressed Bcl-2, in comparison with 20 (24%) of 84 low-stage tumors (P =.07). On univariate analysis, 25 (48%) of the 52 PACs that recurred expressed Bcl-2, as compared with 16 (19%) of the 86 nonrecurrent PACs (P <.001). No correlation was noted between survivin and Bcl-2 expression. CONCLUSION: Survivin is expressed in a majority of PACs and is not a prognosis-related marker, but may be a potential target for apoptosis-based therapy. Overexpression of Bcl-2 correlates with other prognostic variables and predicts disease recurrence of PACs. These data also suggest that survivin and Bcl-2 may regulate cell proliferation and cell death through different mechanisms.
