Trends in genitourinary cancer mortality in the United States: analysis of the CDC-WONDER database 1999–2020

IntroductionSociodemographic disparities in genitourinary cancer-related mortality have been insufficiently studied, particularly across multiple cancer types. This study aimed to investigate gender, racial, and geographic disparities in mortality rates for the most common genitourinary cancers in the United States.MethodsMortality data for prostate, bladder, kidney, and testicular cancers were obtained from the Centers for Disease Control and Prevention (CDC) WONDER database between 1999 and 2020. Age-adjusted mortality rates (AAMRs) were analyzed by year, gender, race, urban–rural status, and geographic region using a significance level of p < 0.05.ResultsOverall, AAMRs for prostate, bladder, and kidney cancer declined significantly, while testicular cancer-related mortality remained stable. Bladder and kidney cancer AAMRs were 3–4 times higher in males than females. Prostate cancer mortality was highest in black individuals/African Americans and began increasing after 2015. Bladder cancer mortality decreased significantly in White individuals, Black individuals, African Americans, and Asians/Pacific Islanders but remained stable in American Indian/Alaska Natives. Kidney cancer-related mortality was highest in White individuals but declined significantly in other races. Testicular cancer mortality increased significantly in White individuals but remained stable in Black individuals and African Americans. Genitourinary cancer mortality decreased in metropolitan areas but either increased (bladder and testicular cancer) or remained stable (kidney cancer) in non-metropolitan areas. Prostate and kidney cancer mortality was highest in the Midwest, bladder cancer in the South, and testicular cancer in the West.DiscussionSignificant sociodemographic disparities exist in the mortality trends of genitourinary cancers in the United States. These findings highlight the need for targeted interventions and further research to address these disparities and improve outcomes for all populations affected by genitourinary cancers

Fetal sex and leptin concentrations in pregnant females

BACKGROUND : Adult females have significantly more leptin than males. We investigated the effect of fetal sex on levels of leptin and other pregnancy hormones (progesterone, estradiol, FSH, LH and âhCG) in pregnant females during different stages of pregnancy. PATIENTS AND METHODS : Serum leptin levels in pregnant females followed at King Khaled University Hospital, Riyadh, Saudi Arabia in the year 2001 were estimated at the first, second, and third trimester of pregnancy as well as after delivery. Progesterone, estradiol, FSH, LH and âhCG levels were also measured. RESULTS : Leptin levels were significantly higher during all three trimesters in the pregnant females carrying female fetuses compared with those with male fetuses, while other hormones did not differ between the two groups. After delivery, the leptin levels decreased in both groups, and were still higher in the females who delivered baby girls, but the results were not statistically significant. CONCLUSION : These finding suggests that leptin might play a role in sex regulation during embryonic development

Bilateral same session renal stone surgery tolerance and complications

Altres ajuts: King Abdullah International Medical Research Center (RC18/318/R).Introduction: The prevalence rate of upper urinary tract calculi in Saudi Arabia is one of the highest globally. Bilateral renal stone management is an option but is still controversial. Methodology: The study was a retrospective study, including 31 patients with bilateral renal or ureteric stones who underwent bilateral same-session ureterorenoscopy (BSS-URS). The data collected included age, gender, body mass index (BMI), stone burden bilaterally, operative time bilaterally, hospital stay, stone location, type of anesthesia, stone history, renal anomaly as well as pre- and postoperative JJ stenting. In addition, data related to complications (ureteric injury, renal failure, urinary tract infection, pain requiring an emergency department visit within 1 week of the procedure), the stone-free rate (defined as £ 3 mm asymptomatic stone fragment identified with computed tomography Kidney, Ureter and Bladder 3 months after surgery was also collected. The data were collected from the electronic patient record system, entered in an Excel spreadsheet, and descriptive analysis was done. Results: In total, 31 patients were included, with the majority (80.6%, n = 25) male. The mean age was 41.6 years, the mean BMI 28.7 ± 5.59, the mean operative time for each renal unit 46.53 ± 25.69 min, and the mean hospital stay 17.87 ± 8.43 h. The majority (96.7%, n = 30) received general anesthesia. Less than half (40.3%, n = 25) of the renal units had stones in multiple calyces and the majority (90.3%, n = 56) of the renal units were stone free at the 3-month follow-up. A small proportion (3.2%, n = 2) of the renal units were polycystic. Prestenting was documented in 40.3% (n = 25) of the renal units and the majority (95.2%, n = 59) were stented postoperatively. Conclusion: BSS-URS is a safe and a highly effective management option for bilateral renal stones

Prevalence of Dietary Supplements Use among Gymnasium Users

Background. Several studies showed that regular gymnasium users use various dietary supplements without comprehension of their potential risks. Objective. To determine the prevalence and dietary supplement intake and assess the awareness of supplement use among regular gymnasium users in Riyadh, Saudi Arabia. Methods. A descriptive cross-sectional study was conducted among regular gymnasium users in Riyadh, Saudi Arabia, between April 2015 and June 2015. A validated structured questionnaire was used. Results. The study included 299 participants. Of these 113 (37.8%) were dietary supplements users and this was more common among males than females (44.7% versus 16.4%). Gender based analysis showed that males were exercising more frequently than females and the type of cardiovascular exercise was more among them. The most commonly used supplements were whey protein (22.1%), amino acids (16.8%), multivitamins (16.8%), creatine (11.5%), and omega 3 (11.5%). The reasons for taking dietary supplements were to improve body shape (47.7%), increase health (44.2%), and improve performance (41.5%). Conclusion. Most of the information about supplements was obtained from unreliable sources. More studies are needed to better understand supplements use and their impact on health in Saudi Arabia

Sedative Drug Use among King Saud University Medical Students: A Cross-Sectional Sampling Study

Introduction. Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Saudi Arabia. The aim of this study was to evaluate the prevalence and factors associated with sedative drug use among medical students in Saudi Arabia. Materials and Methods. A cross-sectional convenience sampling study gathered data by anonymous questionnaire from students enrolled at the King Saud University College of Medicine in 2011. The questionnaires collected data regarding social and demographic variables, sleep patterns, and the use of stimulant and sedative drugs since enrollment. Sedatives were defined as any pharmaceutical preparations that induce sleep. Results and Discussion. Of the 729 students who returned questionnaires, 17.0% reported sedative drug use at some time since enrollment. Higher academic year, lower grade point average, regular exercise, fewer hours of sleep per day, poorer quality of sleep, and the presence of sleeping disorders were found to be significantly associated with sedative drug use. Conclusions. Further study is required to increase our understanding of sedative drug use patterns in this relatively high-risk group, as such understanding will help in the development of early intervention programs
