Serum lipid response to a high-caloric, high-fat diet in agricultural workers during 12 months.
(66/103)
The effect of a gluttony diet in healthy subjects was studied over an observation period of 12 months. Twenty-six agricultural workers, all of them Yemenite Jews, received a high-caloric, high-fat diet, and the changes in serum cholesterol (CH), high-density-lipoprotein-cholesterol, triglycerides, and body weight were assessed. Yemenite Jews as a group are characterized by low serum CH levels and by a low incidence of coronary artery disease. For a period of 7 months the subjects received a diet of 4553 cal/day, more than double their original "Yemenite diet". After this time they resumed their customary low-caloric diet for 3 months, and thereafter for another 2 months they continued with the high-caloric food regimen. The high-caloric, high-fat diet resulted in the expected increase of serum CH. A similar increase of high-density lipoprotein-CH was found. Serum triglyceride levels changed inversely to those of CH. It is suggested that the altered relation of calories derived from carbohydrates to those derived from fats brought about the decrease of triglycerides, and this irrespective of the increased intake of carbohydrates and fats. The rather small gain of body weight over the trial period--despite the doubled caloric intake--is similar to other studies that showed that the ability of normal individuals to gain weight through overeating varies considerably.

Quality of life among breast cancer patients in Yemen.
(68/103)
OBJECTIVE: The objective of this study is to determine the quality of life among breast cancer patients in Yemen based on socio-demographic and clinical characteristics. METHODOLOGY: This study was designed as a cross-sectional study. The data collected from 106 female breast cancer patients who were chosen for recruitment from the outpatient in National Oncology Centre (NOC), Sana'a, Yemen from November 2008 to June 2011. Questionnaires were distributed to the patients during their visit to the outpatient clinics in the center. The instrument of this study consists of two parts: Socio-demographic and the Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. Regarding data analysis, means and SD of subscales were evaluated for descriptive purpose. Analysis of variance (ANOVA) was performed to compare the three groups regarding QOL subscales. Whereas, independent t-test was performed for comparing two groups regarding QOL subscales. Multiple linear regression using backward analysis was performed to obtain the final model for each domain. The final model was chosen depending on R2 and the p value of the model. A p value less than 0.05 is considered statistically significant. RESULTS: A total number of 106 breast cancer patients were participated in this study. The majority of them were uneducated, unemployed with normal weight and had middle income (60.4%; 95.3%; 59.4%, 46.2%; respectively). As for clinical characteristics of the study participants; the majority of them had had no family history of breast cancer, have been diagnosed at least 2 years, were diagnosed at grade 3 and size of tumor greater than 2 cm (88.7%, 66.0%, 35.8%, 73.6%; respectively). The majority of them underwent mastectomy, radiotherapy, chemotherapy and tamoxifen therapy (85.8%, 63.2%, 94.3% and 62.3%; respectively). For univariate analysis, the present study has identified several factors includes family monthly income, BMI, educational status, years after diagnosis, histological grade radiotherapy and surgery that influence the QOL of breast cancer patients in Yemen. For multivariate analysis, years after diagnosis, family monthly income and radiotherapy were significantly associated with total QOL of the breast cancer patients (p=0.01, p=0.023, p=0.039; respectively). CONCLUSION: Family monthly income, BMI, educational status, years after diagnosis, histological grade radiotherapy and surgery were significantly influence the QOL of breast cancer patients in Yemen, in univariate analysis. For multivariate analysis, years after diagnosis, family monthly income and radiotherapy were significantly associated with total QOL of the breast cancer patients. (+info)
Cases of hydatidosis in patients referred to Governmental hospitals for cyst removal in Sana'a City, Republic of Yemen.
(69/103)
Hydatidosis is a parasitic infestation caused by Echinococcus granulosus. This disease is endemic in many countries including Yemen. The present review article aims to have a glimpse at the present status of hydatidosis in Yemen. This is the first descriptive study, investigating recorded cases of hydatidosis from the five main governmental hospitals in the capital Sana'a city, over a longer period starting from 2001 and ending in 2008. A total of 796 medical records of patients referred to the five main governmental hospitals in Sana'a city for cyst removal, were studied. Of these cases 482 were females and 314 were males. Their mean age was 30.0 +/- 16.9 years. Information regarding the location of the cyst in the body, age, sex and residence of each patient was recorded. A higher infection rate was found in females than males (60.6% and 39.4%, respectively). Single organ involvement was observed in 98.6% cases, among which, the most frequent localizations were the liver (60.8%) followed by the lung (24.7%). Cases of hydatidosis appeared to increase during the period 2001-2008, with the lowest number (n=26) and the highest number (n=140) recorded in 2001 and 2007, respectively. We conclude that the risk of hydatidosis is still high in Yemen, where street or stray dogs move freely down town and the population should be aware about the role of dogs in the transmission of this disease. Hospital records provide a useful indication of infection expressed as annual rate of hospital cases. Finally, the collaboration of Public Health Authorities, the Veterinary Medical Authorities and the Environmental Affairs Authorities is a must to control this disease. (+info)
