Methods: The study was conducted from December 2009 to September 2012 in the oncology and ultrasound units in department of obstetrics and gynecology, Ain Shams University on 150 patients with ovarian masses. During preoperative workup, serum Ca-125 levels and serum VEGF levels were obtained. Ultrasonographic examination included two and three dimensional power Doppler ultrasound (3DPD). Laparotomic approaches were undertaken to obtain the final pathologic results. VEGF was measured in one hundred normal cases as controls. Results: Final ovarian pathology revealed seventy three malignant ovarian masses and seventy seven were benign. Serum Ca-125 levels in malignant cases were higher compared to those in benign cases (p < 0.001). Preoperative serum VEGF revealed higher levels in malignant ovarian masses than benign conditions and normal controls (p < 0.001). Three dimensional power Doppler indices, vascularization index (VI), flow index (FI) and vascularization flow index (VFI), correlated positively with serum VEGF levels. Conclusion: Preoperative serum VEGF revealed higher levels in malignant ovarian masses than benign conditions and normal controls. These levels positively correlated with the Doppler vascular indices of the masses.展开更多

Volunteer in the medical field is common. Physicians and medical students are participating in voluntary activities. This study assessed the motivations and barriers of Family Medicine (FM) Residents and Primary Health Care (PHC) Physicians in Qassim Region, Saudi Arabia. Methods: This is a descriptive cross-sectional study was carried out between 12th March 2021 to 31st September 2021 in Qassim Region, Saudi Arabia. 63 FM residents and 89 PHC physicians were involved. A self-administered questionnaire using Volunteer Functions Inventory (VFI) questions was distributed. A 30-item questionnaire is divided into 6 scales of 5 items each, which are scored using a 5-point Likert-type scale (where 1 strongly disagrees and 5 strongly agree). Results: Of 152 FM residents and PHC physicians, 91 (59.9%) were males, and Saudi 90 (59.2%). The mean age was 35 (±SD8.6) years. The majority of respondents 126 (85.7%) participated in different kinds of volunteer work. The highest rank of the benefits selected 137 (90.1%) was gained Allah’s pleasure. About 66 (43.4%) of respondents reported different reasons as barriers;lack of time was the dominant reason for 59 (38.8%). A strong statistical association was found between gender and facing barriers (P-value Conclusions: This study highlighted that the values motivation factor was the highest among the six motivation determinants. The main reason preventing respondents from doing voluntary work was the lack of time. Male gender and Saudi nationality physicians participated more in previous voluntary work P-value < 0.001. Further future research into studying human behaviour towards voluntary work is highly needed.展开更多
目的分析15~岁组廊坊市居民不同体质指数(Body Mass Index,BMI)、腰围(Waist Circumference,WC)、内脏脂肪指数(Visceral Fat Index,VFI)、身体脂肪率(Percentage Body Fat,PBF)等肥胖指标与高血压分布特征的关系,为高血压、肥胖防治工...目的分析15~岁组廊坊市居民不同体质指数(Body Mass Index,BMI)、腰围(Waist Circumference,WC)、内脏脂肪指数(Visceral Fat Index,VFI)、身体脂肪率(Percentage Body Fat,PBF)等肥胖指标与高血压分布特征的关系,为高血压、肥胖防治工作提供科学依据。方法对不同居民BMI、WC、VFI、PBF的分布特征进行分析,并对肥胖与高血压流行关系进行分析。结果在3 775名廊坊市居民中,高血压病人1 103人,患病率29.2%;随BMI、VFI、PBF增长,廊坊市居民高血压患病率呈逐渐升高趋势,差异有统计学意义(χ~2=229.231、160.900、11.834,P<0.01);中心性肥胖居民高血压患病率高于正常居民,差异有统计学意义(χ~2=205.741,P<0.01)。结论廊坊市居民高血压患病与肥胖密切相关,应加强健康教育,使居民养成平衡膳食、适度睡眠、积极锻炼的健康生活方式,以有效控制体重,进一步降低居民高血压患病率。展开更多
