Perceived Stress and Eating Behaviors by Sex,Obesity Status,and Stress Vulnerability: Findings from the Vitamins and Lifestyle (VITAL) Study

Stress has been associated with eating patterns in human studies with differences due to the type and duration of stressor, type of food, and individual susceptibility factors. Laboratory and smaller epidemiological studies have reported stress-associated preferences for foods high in sugar and fat; associations have been found more consistently among women and people who are obese. Larger studies are needed to sufficiently test these relationships. The aim of this study was to evaluate associations between self-reported amount of stress and dietary nutrient intakes (percentage energy from fat, carbohydrates, added sugar) and dietary behaviors (number of eating occasions and servings of fruits and vegetables, high-fat snacks, fast-food items, and sweetened drinks) by sex, obesity status, and stress vulnerability. Linear regression was used to estimate associations of perceived stress with eating patterns among 65,235 older adults while adjusting for demographic factors, body mass index, physical activity, alcohol intake, number of comorbidities, and other relevant covariates. Higher perceived stress was associated with greater intake of energy from fat, high-fat snacks, and fast-food items as well as lower intake of energy from carbohydrates (all P for trend ≤0.002). Among those with high perceived stress vulnerability, perceived stress was associated with fewer eating occasions (P for interaction <0.0001). Although associations were small, significant relationships were found for perceived stress arising from everyday experiences among an older, mostly white population. These findings have public health implications and suggest that stress may be important to consider in programs promoting healthy eating.     

Potassium-rich diet and risk of stroke: Updated meta-analysis

Recently a few prospective population studies provided additional and heterogeneous information concerning the reported statistical associations between potassium (K) intake and stroke risk. Therefore, we updated our previous meta-analysis of K intake and risk of cerebrovascular events.Three studies were added to the previous analysis, and the results of the comparison between the event rate in the two extreme categories of K intake were used. Pooled analysis of 14 cohorts (overall 333,250 participants and 10,659 events) showed an inverse and significant association between K intake and risk of stroke (Relative Risk: 0.80; 95% CI: 0.72–0.90).Our results indicated a favorable effect of higher K intake on risk of stroke. These results confirm the appropriateness of worldwide recommendations for a population increased consumption of potassium-rich foods to prevent cardiovascular disease.     

A qualitative study to develop an instrument for initial nurse assessment

Complex health care needs focus on accountability and necessity of inclusion of nurses in documenting and monitoring clinical care plans have brought in the concept of initial nurse assessment and nursing process. However, no standardized form exists in the Armed Forces Medical Services to document initial nursing observations while a patient is being admitted in service hospitals.A focus group design was utilized to explore and conceptualize an initial nurse assessment form that may be utilized by service hospitals.     

艾滋病元素医学食疗中心

笔者自2003年至2006年用元素医学食疗法治疗40余例艾滋病获突破，其中完全治愈两人，一个5岁小女孩、一个是65岁老人。2006年5月40岁中年妇女，在进行Hiv病毒抗体检验开始转阴，病人为生活所迫外出打工终止食疗，于6月份再7欠进行Hiv病毒抗体检验又转变为阳性。笔者于是决定对即将痊愈艾滋病人集中食疗，效果非常有效，建立艾滋病元素医学食疗中心是个好办法。

Histopathology and apoptosis in an animal model of reversible renal injury

High adenine phosphate (HAP) diet serves as an animal model of chronic renal failure (RF). Induction of RF and establishment of end organ damage require long exposure periods to this diet. Previously, we have shown that RF is reversible after diet cessation even after protracted administration. In this study, we explored the underlying renal changes and cellular pathways occurring during administration and after cessation of the diet. Kidneys were obtained from rats fed HAP diet for 7 weeks, and from rats fed HAP diet followed a 10 week recovery period on normal diet. The kidneys of HAP diet group were significantly enlarged due to tubular injury characterized by massive cystic dilatation and crystal deposition. Kidney injury was associated with markers of apoptosis as well as with activation of apoptosis related pathways. Diet cessation was associated with a significant reduction in kidney size, tubules diameter, and crystals deposition. The recovery from renal injury was coupled with regression of apoptotic features. This is the first study showing the potential reversibility of long standing RF model, allowing optimal evaluation of uremia-chronic effects.     

Colorectal cancer in Egypt

PURPOSE: The aim of this study was to review the age distribution and pathology features of colorectal cancer in Egypt. METHODS: A seven-year review (retrospective in first six years, prospective in the seventh) of all colorectal adenocarcinoma patients (N = 177; 104 males; mean age, 46; range, 19–74 years) presented to the Department of Surgery, Ain Shams University, was performed. Data from three other major hospitals throughout the country were retrieved and compared with Ain Shams data. Retrospective data were retrieved from patients files and surgery and pathology records. Family history of colorectal cancer and other characteristic hereditary nonpolyposis colorectal cancer tumors was obtained prospectively in all patients. RESULTS: According to Ain Shams data, the disease had no predilection to a specific age group. Thirty-eight percent of the tumors occurred in patients aged less than 40 years, and only 15 percent of patients were aged above 60 years. None of the young patients fulfilled the Amsterdam criteria for hereditary nonpolyposis colorectal cancer. Seventy-five percent of tumors occurred in the left side, 3 percent were Dukes A, and 58 percent were Dukes C. Synchronous and metachronous tumors occurred in 2.8 and 4.5 percent of patients, respectively. Adenomas were present in 5.6 percent of patients and bilharziasis in 3.4 percent of resection specimens. Data from different centers were remarkably similar to Ain Shams results. CONCLUSION: Colorectal cancer in Egypt has no age predilection and more than one-third of tumors affects a young population. The high prevalence in young people can neither be explained on a hereditary basis nor can it be attributed to bilharziasis. The disease usually presents at an advanced stage, and predisposing adenomas are rare. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.     

Associations of multiple unhealthy lifestyle behaviors with overweight/obesity and abdominal obesity among Brazilian adolescents: A country-wide survey

Background and Aims

Physical inactivity, unhealthy diet, smoking and heavy drinking are four key unhealthy lifestyle behaviors (ULB) that may influence body weight and obesity development. More recently, sedentary time has been recognized as another potentially emerging ULB related to obesity. We therefore investigated the association of multiple ULB with overweight/obesity and abdominal obesity among Brazilian adolescents.
