Perceived Health Status and Influencing Factors for the Extreme Elderly in Rural Areas

Perceived health status is one of the important meansof evaluating quality of life,1 and has attracted increas-ing attention as a focus of research. Studies have pointedout that perceived health status is important in affectinghealth seeking behaviors because people will only seekmedical attention when they perceive that they areunhealthy. Furthermore, aside from age and sex, per-ceived health status has been recognized as the stron-gest “early-warning index” for pre-estimating deathrates.2-5 Prior studies ...     

湖北省部分地区农民工生活质量及相关影响因素调查

Objective The aim of the study was to understand the quality of life and the related factors of farmer workers in the countryside of Hubei province. Methods Purposive sampling was used to select 529 farmer workers and another 326 government workers were served as controls.'Group investigation' method was used in this study, t-test was used to compare the quality of life among farmer workers and the Chinese norm. SF-36 was used to measure the quality of life. Generalized linear regression model(GLM)and structural equation model(SEM)were applied to test the related factors. Results Quality of life among farmer workers in Hubei was significantly different from the norm of residents in Hangzhou. The quality of life among migrant workers was significantly lower than the government staff(PRP＜0.05, PBP＜0.05, PVT＜0.05)after controlling the confounding factors. Factors as age(B=-0.33), sex(B=-0.07), marital status(B=-0.10),sleeping habits(B=-0.16), fatigue(B=-0.12), life style(B=-0.05)and social status(B=0.93)etc. were related to the quality of life. Conclusion The quality of life among farmer workers was poor, and mainly affected by age, sex, marital status, sleeping habits, fatigue, lifestyle and social status. It is important to reduce the work load and making the work status and life style reasonable to better the quality of life among the farmer workers.

低蛋白饮食对3/4期慢性肾脏病患者肾功能及营养状况的影响

Objective To assess the influences of low-protein diet on the renal function and nutritional status in patients with stage 3/4 chronic kidney diseases (CKD).Methods Totally 34 patients with stage 3/4 CKD were randomly divided into group A (protein intake:0.6 g·kg~(-1)·d~(-1);n=14) and B (protein intake:0.8 g·kg~(-1)·d~(-1);n=20).Anthropometric measurement and blood biochemical tests were performed,nutri-tional status was assessed,and 24-hour dietary recall survey was conducted before and after the treatment.Patients were followed up for 6 months.Results In group A,the creatinine level significantly decreased (P=0.010),while albumin level (P=0.042) and the intake of energy (P=0.018) and carbohydrate (P<0.001) signifi-cantly increased after the treatment In all the 34 patients,in group A and group B,the malnutrition rates were de-creased by 14.7%,7.2%,and 21.1% after nutritional intervention.Conclusion The low-protein diet (protein intake 0.6 g·kg~(-1)·d~(-1)),in which part of the staple food was replaced by wheat starch,can increase the in-takes of carbohydrate and energy and improve renal function and nutritional status in patients with stage 3/4 CKD.     

营养风险筛查2002的临床应用和分析

Objective To evaluate the clinical application of Nutritional Risk Screening 2002 (NRS 2002) in inpatients.Methods Totally 400 inpatients who were admitted to Tianjin Tianhe Hospital from Novem- ber 2008 to March 2009 were enrolled in this study.Physical examinations,including body height and body meas-urement,were performed the next morning after admission.The nutritional status was evaluated with NRS 2002.Results In all 400 inpatients.NRS 2002 was strongly practicable in 306 patients (76.5%) and weakly practica-ble in 94 patients (23.5%);Ninety-six patients (24.0%) had nutritional risks,which were most common in the department of internal medicine and the Department of neurology.The average age of patients with nutritional risks was (79.0±11.4) years,which was significantly higher than that of patients without nutritional risks [(58.1±15.8) years] (P<0.01).Conclusion NRS 2002 is effective and practicable in evaluating the nutritional status of inpatient.

三阴乳腺癌与非三阴乳腺癌预后的比较分析

Objective To assess whether survival differed among patients who had triple-negative breast cancers compared with patients who had non-triple-negative breast cancers.Methods The clinicopathologic data of 684 patients with operable breast cancer,who were treated with multimodal therapy from December 1998 to June 2007 were analyzed.Of these patients,107 cases were confirmed to have triple-negative tumor histology(triple-negative group),577 cases were confirmed to have non-triple-negative tumor histology(non-triple-negative group).The 7 years cumulative survival and disease-free survival were analyzed by Kaplan-Meier method and compared by Log-rank test.The prognosis Was analyzed by COX regression model.Results The 7 years overall survival rates for triple-negative group and non-triple-negative group were 51.4%(55/107),74.2%(428/577),respectively,there Was significant difference between the two groups(P＜0.01).However,the 7 years overall survival rates of patients with triple-negative group and those who with Her-2 positive were 51.4%(55/107)and 53.1%(43/81)respectively,there Was no significant difference between them (P＞0.05).Univariate analysis revealed that the factors affecting the disease-free survival included age,menopausal status,tumor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status.Multivariate analysis showed minor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status were independent prognostic factors.Conclusions This study has shown a trend towards a poorer outcome for patients with triple-negative breast cancer similarity to patients with Her-2 positive cancers.Triple-negative breast cancer is an independent predictor factor of survival.
