BACKGROUNDAging of population in Macau has become a serious problem and we are diagnosing more and more patients with prostate cancer. To investigate the effect of ethnicity and environment on incidence of prostate carcinoma, we compared the difference of biopsy and postoperative pathology of prostate between indigenous Chinese (Chinese) and Chinese of Portuguese descent (Portuguese) with elevated serologic prostate specific antigen (PSA) and incidence of prostate carcinoma in Macau.

METHODSBetween 1999 and 2006, prostate biopsy was performed in a random sample of 462 patients with elevated serologic PSA who, on followup, were diagnosed in this hospital with benign prostate hyperplasia. Of these, 416 were indigenous Chinese, 46 Portuguese. Based on demographic statistics by Macau government for 2005, we compared differences in incidences of prostate carcinoma, positive rate of random prostate biopsy in patients with elevated serologic PSA, factors related to serological PSA and pathological grade and stage between both ethnic groups.

RESULTSProstate carcinoma was diagnosed on biopsy in 178 cases. Positive biopsies of prostate carcinoma were present in 160 Chinese with positive rate of 38.5% and in 18 Portuguese with 39.1%. For patients diagnosed with prostate carcinoma, there was no significant difference in age, incidence, grade of cancerous cells, stage of the disease, incidence of inflammation of prostatic tissues or prostatic intraepithelial neoplasia (PIN) related to elevated PSA between the groups (All P>0.05).

CONCLUSIONSThere was no significant difference in incidence or characteristics of prostate carcinoma between people of Portuguese and Chinese descent in Macau based on our limited data. Long term residence in the same environment may be associated with the incidence and progression of prostate carcinoma in Portuguese living in Macau, but further rigorous epidemiological investigation and analysis of risk factors about prostate carcinoma are needed to corroborate this conclusion.

PURPOSE: Myocardial infarction can occur due to known risk factors and lifestyle choices. The difficulties that patients experience after discharge can lead to readmission and nonadherence to lifestyle change. The purpose of this study was to analyze the difficulties experienced by patients after hospitalization due to myocardial infarction and to identify the predictors of readmission and unchanged lifestyles. METHODS: The study used a mixed-methods design across 106 patients who had experienced a first episode of acute myocardial infarction. The data were collected from two patient interviews and the patients' medical records. A logistic regression was used to predict unchanged lifestyle and readmission. RESULTS: In the first interview, 74.5% of the patients reported receiving information prior to discharge. Six months after discharge, 80.2% mentioned that they had changed their lifestyles, but only 59.4% reported that their health had improved, and 75.5% continued to have concerns regarding their health. Patients described difficulties with regard to psychological problems, family dynamics, professional issues, problems with managing cardiovascular symptoms, and complications associated with hospital interventions. A follow-up assessment revealed that 12.3% of patients had been readmitted for cardiovascular disease. CONCLUSIONS: The analysis revealed significant predictors of readmission amongst patients with hypertension and three-vessel disease. Specifically, the number of people in the household, per capita income, and a lack of information/education provided at discharge as well as problems related to mental health after discharge predicted unchanged lifestyle. An educational program might be advantageous to clarify doubts and involve patients in their own disease management.
