Abstract
BACKGROUND Telomerase reverse transcriptase (TERT) gene promoter mutations have been explored, as biomarkers of improved survival for patients with cancer receiving immune checkpoint inhibitors. We sought to investigate their prevalence by race and sex across different cancer types to inform patient selection in clinical trials. RESULTS In this observational study, 31 925 patients with cancer underwent next-generation sequencing of their tumors with 88% (27 970) patients self-reported being Whites, 7.1% (2273) Asians, and 5.3% (1682) Blacks. Examining the distribution of TERT promoter mutations by race, White patients with melanoma harbored more TERT promoter mutations than Asian and Black patients (OR = 25.83; 95%CI, 6.84-217.42; P < .001). In contrast, Asian patients with head and neck cancer (HNC) harbored more TERT promoter mutations compared to White patients (OR = 2.47; 95%CI, 1.39-4.37; P = .004). In addition, the distribution of TERT promoter mutations differed by sex. Males were enriched for TERT gene promoter mutations compared to females with melanoma (OR = 1.82; 95%CI, 1.53-2.16; P < .001), cancer of unknown primary (OR = 1.96; 95%CI, 1.43-2.69; P < .001), hepatobiliary (OR = 3.89; 95%CI, 2.65-5.69; P < .001), and thyroid cancers (OR = 1.42; 95%CI, 1.10-1.84; P = .0087), while females were more enriched for TERT promoter mutations compared to males for HNC (OR = 0.56; 95%CI, 0.39-0.81; P = .0021). CONCLUSIONS The prevalence of TERT gene promoter mutations varies among patients with cancer based on race and sex. These findings inform our understanding of cancer biology and can assist in the design of future clinical trials that leverage drugs targeting TERT promoter dependencies.

Abstract
BACKGROUND The Arab region comprises 22 countries located in the Middle East and North Africa, sharing cultural and linguistic ties. Arab countries have continued to lag in terms of biomedical research compared to other nations for several past decades. Cancer is a major public health concern, being the second leading cause of death globally. Given that high research activity on cancer reflects positively on screening programs, awareness, and clinical practice, this article aimed to examine the activity and trend of cancer research in the Arab world between 2005 and 2019. METHODS Between 2005 and 2019, the number of cancer-related articles published by each Arab country, and regarding 27 different types, was assessed using the PubMed database. Numbers were normalized with respect to each country's average population and average Gross Domestic Product (GDP). RESULTS Arab countries contributed to 1.52% of total cancer publications. The number of cancer publications has steadily grown since 2005, with the last 7 years alone witnessing 75.69% of the total Arab cancer-related publications. In terms of publications per million persons, Qatar ranked first (393.74 per million persons), while in terms of publications per national GDP, Egypt ranked first (464.27 per billion US dollars). Breast, liver, and colorectal cancers had the highest numbers of all Arab cancer-related publications, while testicular, vulvar, and gallbladder cancers had the least. CONCLUSIONS This paper pools information and insight for scientists, clinicians, funders, and decision-makers on the actualities and developments of cancer research in the Arab world. Addressing the barriers facing cancer research remains a cornerstone in the plan to improve the Arab world's output and contribution to the field of oncology.

Abstract
Background and Objectives Hypertension (HTN) is a major health concern that leads to cardiovascular disease and premature death. Assessing HTN knowledge, attitude, and practice (KAP) is crucial for controlling HTN. This study aimed to determine HTN KAP among hypertensive patients residing in Lebanon. Methods This cross-sectional study involved 342 hypertensive patients. A questionnaire form was used to collect data related to patients’ characteristics. SPSS was used to determine KAP scores, descriptive statistics, and correlations. Results Data from HTN patients was analyzed of whom 98.2% were Lebanese and 51.2% were males. The median age was 59.15 ± 13.55 years old. A proportion of 40.4% had HTN duration for at least 10 years and 67.3% had HTN family history. Patients had fair HTN knowledge and practice, but good attitude toward HTN. Only 45.3% regularly checked their blood pressure. Positive correlations were observed between HTN attitude and each of knowledge and practice. HTN knowledge and attitude were associated with many studied factors, whereas no relationship was found regarding practice. Conclusion Hypertensive patients had fair levels of knowledge and practice, and a good level of attitude concerning their disease. We provided a model for predictors of HTN KAP scores that will allow the development of efficient campaigns related to HTN.

Abstract
Simple Summary Despite improvements in standardized screening methods and the development of promising therapies for colorectal cancer (CRC), survival rates are still low. Drug repurposing offers an affordable solution to achieve new indications for previously approved drugs that could play a protagonist or adjuvant role in the treatment of CRC. In this review, we summarize the current data supporting drug repurposing as a feasible option for patients with CRC. Abstract Colorectal cancer (CRC) is the third most common cancer in the world. Despite improvement in standardized screening methods and the development of promising therapies, the 5-year survival rates are as low as 10% in the metastatic setting. The increasing life expectancy of the general population, higher rates of obesity, poor diet, and comorbidities contribute to the increasing trends in incidence. Drug repurposing offers an affordable solution to achieve new indications for previously approved drugs that could play a protagonist or adjuvant role in the treatment of CRC with the advantage of treating underlying comorbidities and decreasing chemotherapy toxicity. This review elaborates on the current data that supports drug repurposing as a feasible option for patients with CRC with a focus on the evidence and mechanism of action promising repurposed candidates that are widely used, including but not limited to anti-malarial, anti-helminthic, anti-inflammatory, anti-hypertensive, anti-hyperlipidemic, and anti-diabetic agents.

Abstract
BACKGROUND The Arab world consists of 22 countries situated in the Middle East and North Africa, tied together by linguistic and cultural bonds. Over numerous past decades, this region tended to fall behind regarding biomedical research. Organ, tissue, and cell transplantation are life-saving and life-improving treatments for various diseases. Given the positive correlation between research activity and the improvement of the clinical frame of transplantation, this article intended to examine the regional activity of transplantation research between 2005 and 2019. METHODS Using the PubMed database, the number of transplantation-related articles published by each country, and regarding 26 different procedures, was assessed. The results were normalized with respect to each country's average population & average Gross Domestic Product (GDP). In addition, the co-occurrence of keywords and the co-authorships were analyzed by VOS Viewer. RESULTS Arab countries contributed to 1.25% of total transplantation publications. The number of transplantation publications had an inflection in 2013, with the last six years alone contributing to 65.27% of the overall regional transplantation-related publications. Kuwait and Lebanon ranked first in terms of publications per million persons, while Egypt ranked first in terms of publications per national GDP. Stem cell, bone & kidney transplantations had the highest number of Arab transplantation-related publications. Low levels of collaboration between authors and organizations were observed, besides a modest but increasing trend towards experimental work on animals and newer therapies. CONCLUSION Despite the increase in transplant-related research activity in recent years, the Arab world still lags behind in this field compared to the worldwide contribution.
