Introduction Liver cancer (LC) is frequently preceded by cirrhosis and poses a significant public health challenge in the United States (US). Recent decades have seen notable shifts in the epidemiological patterns of LC, yet national data guiding the optimal allocation of resources and preventive efforts remain limited. This study aims to investigate the current trends, risk factors, and outcomes of LC in the US. Methods This study utilized the Global Burden of Disease (GBD) dataset to collect data on the annual incident cases, deaths, Disability-Adjusted Life Years (DALYs), age-standardized incidence rates (ASIR), age-standardized death rates, and age-standardized DALY rates of primary LC and its etiologies and risk factors, between 1990 and 2019. Percentage changes in incident cases, DALYs, and deaths and the estimated annual percentage change (EAPC) in ASIR and deaths rates of LC were calculated to conduct temporal analysis. Linear regression was applied for the calculation of EAPCs. Correlations of EAPC with socio-demographic index (SDI) were separately evaluated by Pearson correlation analyses. Results We observed a marked increase in the ASIR of LC, increasing from 2.22 (95% CI: 2.15–2.27) per 100,000 people in 1990 to 5.23 (95% CI: 4.28–6.29) per 100,000 people in 2019, a percentage change of 135.4%. LC due to hepatitis C followed by alcohol use were the primary factors driving this increase. The ASIR and age-standardized death rates of LC showed a significant average annual increase of 3.0% (95% CI: 2.7–3.2) and 2.6% (95% CI: 2.5–2.8), respectively. There was a significant negative correlation between the SDI and the EAPC in ASIR ( ρ = -0.40, p  = 0.004) and age-standardized death rates ( ρ = -0.46, p  < 0.001). In 2019, drug and alcohol use, followed by elevated body mass index (BMI) were the primary risk factors for age-standardized DALY rates attributable to LC. Conclusion The increased burden of LC in the US highlights the need for interventions. This is particularly important given that LC is mostly influenced by modifiable risk factors, such as drug and alcohol use, and elevated BMI. Our findings highlight the urgent need for public health interventions targeting socio-economic, lifestyle, and modifiable risk factors to mitigate the escalating burden of LC.

Background Cardiovascular Disease (CVD) is the leading cause of mortality worldwide. While countries in the Arab world continue to lack public health data and be severely understudied in health research, previous research has shown that compared to 1990, CVDs had a higher burden of disease in the Arab World in 2010. Jordan, a middle-income Arab country, is profiled with unique attributes such as a dual-sector healthcare system, political stability, and its role as a haven for refugees and migrants. These distinctive factors emphasize Jordan’s suitability as a case study. This investigation aims to quantify CVD burden in Jordan and identify risk factors, contributing to a broader understanding of health challenges in the Arab region and beyond. Methods The Global Burden of Disease (GBD) dataset was used to estimate prevalence, death, and disability-adjusted life-years (DALYs) as age-standardized rates from 1990 to 2019. We calculated percentage change for nine specific CVDs and reported trends by gender and age groups. Additionally, data on twelve a priori selected behavioral, clinical, and environmental risk factors attributing to overall age-standardized CVDs DALY were reported per 100,00 population. Results In 2019, the age-standardized CVD prevalence, death, and DALYs rates in Jordan were 7980 (95% uncertainty interval [UI] 7629, 8360), 248 (95% UI 211, 288), and 4647 (95% UI 4028, 5388), respectively. Despite an increase in the absolute number of mortality and prevalence, between 1990 and 2019, the age-standardized prevalence, death, and DALYs rates all decreased by 5.5%, 45.1%, and 46.7%, respectively. In 2019, the leading risk factors contributing to overall age-standardized CVDs DALY per 100,000 population were high systolic blood pressure, high BMI, dietary risks, and high LDL cholesterol. Conclusion Despite decreasing burden rate of CVDs in Jordan between 1990 and 2019, CVDs remain the leading cause of mortality in Jordan, with an increase in the total number of prevalence and mortality. Overall, this contributes to increased healthcare costs. Further research is required to quantify the burden of CVDs and understand it better. Intervention measures and policies tailored to specific CVDs should be designed to reduce the burden of CVDs in Jordan.

Background Little is known about gender disparity among medical undergraduates in the developing world. Therefore, this study aims to explore the attitudes and perceived barriers among Jordanian medical students, particularly women. Methods An online, self-administered questionnaire, developed after an extensive literature review, was disseminated across all six Jordanian medical schools targeting more than 5000 medical students. Student t -test and ANOVA were used to document mean differences among different groups. Linear and logistic regression models were used to find predictors of publication and number of publications. Results A total of 636 students participated in the survey with a women to men ratio of 1.1. Women medical students report significantly higher knowledge ( t (634) = 2.47, p = 0.013), personal ( t (634) = 3.31, p = 0.001), and total barriers scores than men ( t (634) = 3.02, p = 0.003). Moreover, compared to men, women were less likely to find same-sex mentorship ( t (634) = 3.18, p = 0.001) or receive credited authorship ( t (634) = 2.12, p = 0.011). Overall, women medical students were more likely to perceive that their gender ( t (634) = 3.58, p < 0.001) and people’s perception of their gender ( t (634) = 4.25, p < 0.001) are barriers to their career advancement. Binary logistic regression demonstrated that gender is a significant predictor of being able to publish (OR: 1.645; 95%CI: 1.002–2.731), while linear regression demonstrated that gender is a predictor of number of publications (ß: 0.113; 95%CI: 0.063–0.288). Conclusion A significant gender disparity exists in terms of both attitudes and overall barriers among Jordanian medical undergraduates which calls for immediate policy changes as to produce successful clinicians and researchers.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating side effect of cancer treatment. Characterized by symptoms like pain, numbness, and muscle weakness, CIPN significantly impacts patients’ quality of life. Current management strategies vary, with limited consensus on effective treatments. This scoping review aims to explore comprehensive rehabilitation interventions for CIPN, focusing on enhancing patient well-being and functional abilities. Methods: A scoping review, guided by Arksey and O’Malley’s framework and Levac et al.’s refinements, was conducted to assess rehabilitation programs for CIPN. Searches across six databases were performed, with inclusion and exclusion criteria focusing on studies with physical rehabilitation interventions. Data were charted, detailing interventions, demographics, and outcomes. Results were synthesized descriptively and presented narratively with tables. Results: The review included 24 studies covering diverse cancer types and treatments, involving a total of 1167 participants. Various interventions for CIPN were assessed, and results were thematically categorized according to exercise category. Physical modalities like ultrasound and exercise showed promise in symptom relief for colorectal and breast cancer patients. No distinct advantage was found in the timing of exercise interventions. Complementary therapies such as acupuncture and yoga demonstrated effectiveness in managing CIPN symptoms. Conclusions: This review highlights the effectiveness of diverse physical and complementary interventions in managing CIPN, advocating for their integration into standard protocols. It emphasizes the need for holistic, patient-centered approaches that combine exercises, physical therapy, and complementary therapies to improve patient outcomes. These findings set a direction for future research and clinical practices focused on comprehensive and personalized CIPN management strategies.

Resistance of cancer cells and normal tissue toxicity of ionizing radiation (IR) are known to limit the success of radiotherapy. There is growing interest in using IR with natural compounds to sensitize cancer cells and spare healthy tissues. Thymoquinone (TQ) was shown to radiosensitize several cancers, yet no studies have investigated its radiosensitizing effects on colorectal cancer (CRC). Here, we combined TQ with IR and determined its effects in two-dimensional (2D) and three-dimensional (3D) culture models derived from HCT116 and HT29 CRC cells, and in patient-derived organoids (PDOs). TQ sensitized CRC cells to IR and reduced cell viability and clonogenic survival and was non-toxic to non-tumorigenic intestinal cells. TQ sensitizing effects were associated with G2/M arrest and DNA damage as well as changes in key signaling molecules involved in this process. Combining a low dose of TQ (3 µM) with IR (2 Gy) inhibited sphere formation by 100% at generation 5 and this was associated with inhibition of stemness and DNA repair. These doses also led to ~1.4- to ~3.4-fold decrease in organoid forming ability of PDOs. Our findings show that combining TQ and IR could be a promising therapeutic strategy for eradicating CRC cells.
