Profiling estrogen, progesterone, and androgen receptors in colorectal cancer in relation to gender, menopausal status, clinical stage, and tumour sidedness
BackgroundAlthough estrogen (ERα/ERβ), progesterone (PGR), and androgen (AR) receptors are pathologically altered in colorectal cancer (CRC), their simultaneous expression within the same cohort of patients was not previously measured.MethodsERα/ERβ/PGR/AR proteins were measured in archived paired normal and malignant colon specimens (n =120 patients) by immunohistochemistry, and results were analyzed by gender, age (≤50 vs. ≥60 years), clinical stages (early-stage I/II vs. late-stage III/IV), and anatomical location (right; RSCs vs. left; LSCs). Effects of 17β-estradiol (E2), progesterone (P4), and testosterone alone or combined with the specific blockers of ERα (MPP dihydrochloride), ERβ (PHTPP), PGR (mifepristone), and AR (bicalutamide) on cell cycle and apoptosis were also measured in the SW480 male and HT29 female CRC cell lines. ResultsERα and AR proteins increased, whilst ERβ and PGR declined markedly in malignant specimens. Moreover, male neoplastic tissues showed highest AR expression, whilst ERβ and PGR weakest alongside ERα strongest expression was seen in cancerous tissues from women aged ≥60 years. Late-stage neoplasms also revealed maximal alterations in the expression of sex steroid receptors. By tumor location, LSCs disclosed significant elevations in ERα with marked declines in PGR compared with RSCs, and ERα strongest alongside PGR weakest expression was detected in advanced LSCs from women aged ≥60 years. Late-stage LSCs from females aged ≥60 years also showed weakest ERβ and strongest AR expression. In contrast, male RSC and LSC tissues exhibited equal ERβ and AR expression in all clinical stages. ERα and AR proteins also correlated positively, whereas ERβ and PGR inversely, with tumor characteristics. Concomitantly, E2 and P4 monotherapies triggered cell cycle arrest and apoptosis in the SW480 and HT29 cells, and while pre-treatment with ERα-blocker enhanced the effects of E2, ERβ-blocker and PGR-blocker suppressed the E2 and P4 anti-cancer actions, respectively. In contrast, treatment with the AR-blocker induced apoptosis, whilst co-treatment with testosterone hindered the effects. ConclusionsThis study advocates that protein expression of sex steroid receptors in malignant tissues could represent prognostic markers, as well as hormonal therapy could provide an alternative strategy against CRC, and their efficacies could be dependent on gender, clinical stage, and tumor location
CLINICAL CARE PATHWAY AND MANAGEMENT OF MAJOR BLEEDING ASSOCIATED WITH NON-VITAMIN K ANTAGONIST ORAL ANTICOAGULANTS: A MODIFIED DELPHI CONSENSUS FROM SAUDI ARABIA AND UAE
Background: The non-vitamin K antagonist oral anticoagulants (NOACs) have become the mainstay anticoagulation therapy for patients requiring oral anticoagulants (OACs) in the Gulf Council Cooperation (GCC) countries. The frequency of NOAC-associated major bleeding is expected to increase in the Emergency Department (ED). Nonetheless, we still lack local guidelines and recommendations for bleeding management in the region. The present Delphi-based consensus aims to establish a standardized and evidence-based clinical care pathway for managing NOAC-associated major bleeding in the Kingdom of Saudi Arabia (KSA) and the United Arab Emirates (UAE).
Methods: We adopted a three-step modified Delphi method to develop evidence-based recommendations through two voting rounds and an advisory meeting between the two rounds. A panel of 11 experts from the KSA and UAE participated in the consensus development.
Results: Twenty-eight statements reached the consensus level. These statements addressed key aspects of managing major bleeding events associated with NOACs, including the increased use of NOAC in clinical practice, clinical care pathways, and treatment options.
Conclusion: The present Delphi consensus provides evidence-based recommendations and protocols for the management of NOAC-associated bleeding in the region. Patients with major NOAC-induced bleeding should be referred to a well-equipped ED with standardized management protocols. A multidisciplinary approach is recommended for establishing the association between NOAC use and major bleeding. Treating physicians should have prompt access to specific reversal agents to optimize patient outcomes. Real-world evidence and national guidelines are needed to aid all stakeholders involved in NOAC-induced bleeding management
Insight into Current Practices of Community Pharmacists in Topical Corticosteroid Prescribing and Counseling: Cross-Sectional Survey Study from Saudi Arabia
Background: Topical corticosteroids are commonly used to treat several skin conditions, most notably atopic dermatitis. Many studies have found that patients lack knowledge about the safety, potency, and appropriate use of topical corticosteroids. This can be due to ineffective education by pharmacists and other healthcare providers. This study aims to evaluate the appropriateness of dispensing and counseling practices of community pharmacists towards topical corticosteroids in Saudi Arabia. Methods: A cross-sectional survey study was conducted in Saudi Arabia among 418 community pharmacists from different regions of Saudi Arabia. Data were collected using a validated questionnaire that covered community pharmacists’ sociodemographic information, their perceptions of patient knowledge about topical corticosteroid use, and their dispensing and their counseling practices, in addition to their perceived barriers to counseling. Results: The majority of the participating community pharmacists were Saudi (57.4%), female (66.7%), holding a bachelor’s degree (63.4%), and full-time workers (91.1%). Most of the time, community pharmacists counseled patients on the frequency of application per day and the duration of treatment (75.8% and 74.8%, respectively). The median counseling practice score was 17, with an IQR of 14–21. The main barrier to counseling was lack of time (33.7%). Only 15% of community pharmacists accurately identified all scenarios that necessitate medical referrals. Dry skin, itchiness, and irritation were the most common side effects reported by community pharmacists for patients to complain about (69.4%). Most pharmacists agreed that misuse is the most likely cause of topical corticosteroid adverse drug events (53.7%), followed by medication overuse, such as patient self-treatment (48%). Conclusion: Community pharmacists counseling practices to their patients about the use of topical corticosteroids require improvement. Continuing education and hands-on training are needed for community pharmacists regarding counseling about topical corticosteroids use
Burnout and Its Relation to Emotion Dysregulation and Social Cognition among Female Interns and Undergraduate Dental Students at King Khalid University
Background: Burnout is a state of vital exhaustion that has a high global prevalence among dental professionals. Yet the early diagnosis of this syndrome is challenging due to its multidimensional nature. Aim: To assess burnout and its relation to emotional dysregulation and social cognition among undergraduate dental students. Methods: We mailed 148 self-administered questionnaires to all interns and undergraduate dental students belonging to the College of Dentistry’s female campus at King Khalid University, Saudi Arabia. A questionnaire was designed comprising three measuring instruments of psychological inventories to assess work-related stress, namely, burnout (Copenhagen burnout inventory questionnaire (CBI)), emotional dysregulation (emotion regulation questionnaire (ERQ)), and social cognition (interpersonal reactivity index (IRI)). We examined the difference in burnout between two cohorts (interns and undergraduates) using Student’s ‘t’ test and the association between emotional regulation/social cognition domains using Pearson’s correlation. Results: Among the participants, around 70% obtained higher scores than the cut-off points for personal and work-related domains in both groups. There was no statistically significant difference in burnout domain between the two cohorts (p > 0.05; Cohen d < 0.3). A negative correlation existed between burnout and emotion regulation, i.e., higher burnout score is associated with lesser cognitive reappraisal and more expressive suppression (CBI—personal burnout r = −0.251; r = −0.220 respectively). Social cognitive scores had various associations among interns and undergraduates, with personal distress being significantly associated with greater burnout levels among both groups (p < 0.05). Conclusions: The present study revealed significantly elevated burnout levels among both interns and undergraduate students. Emotional dysfunction and social cognition assessment can be a valuable adjunct in identifying this erosive syndrome. Early recognition and primordial prevention targeting burnout are strongly recommended

Demographic Characteristics and Status of Vaccinated Individuals with a History of COVID-19 Infection Pre- or Post-Vaccination: A Descriptive Study of a Nationally Representative Sample in Saudi Arabia
Background: Saudi Arabia expedited the approval of some COVID-19 vaccines and launched mass vaccination campaigns. The aim of this study was to describe the demographics of vaccinated COVID-19 cases and compare the mortality rates of COVID-19 cases who were infected post-vaccination in Saudi Arabia. Methods: This was a retrospective cohort study. We retrieved data for COVID-19 cases who were infected pre- or post-vaccination and had received at least one injection of the Oxford–AstraZeneca or Pfizer–BioNTech vaccine from 4 December 2020 to 15 October 2021. Results: The number of patients who were infected and had received at least one dose of a COVID-19 vaccine was 281,744. Approximately 45% of subjects were infected post-vaccination, and 75% of subjects had received the Pfizer–BioNTech vaccine. Only 0.342% of the patients who were infected post-vaccination died, and 447 patients were admitted to ICUs. Most of the patients who were infected with COVID-19 post-vaccination and were admitted to ICUs (69.84%) had received only one dose of the vaccine (p < 0.0001). The mean time to infection for patients who had received one and two doses of the Oxford–AstraZeneca vaccine were 27 and 8 days longer than their counterparts who had received one and two doses of Pfizer–BioNTech vaccine, respectively. No difference in the odds of mortality between the Pfizer–BioNTech and Oxford–AstraZeneca vaccines was found (OR = 1.121, 95% CI = [0.907–1.386], p-value = 0.291). Patients who had received two doses of the vaccine had significantly lower odds of mortality compared to those who had received one dose (p < 0.0001). Conclusions: Vaccines are vital in combating the COVID-19 pandemic. The results of this study show no difference between the Pfizer–BioNTech and Oxford–AstraZeneca vaccines in the rate of mortality. However, the number of vaccine doses was significantly associated with a lower risk of mortality. Future studies should examine the effectiveness of different COVID-19 vaccines using real-world data and more robust designs
Clinical and therapeutic characteristics of cancer patients in the southern region of Saudi Arabia : a cross-sectional study
Aims: Due to the continuous changes in modern lifestyle and the need to explore the effect of these changes on the risk of developing cancer, ongoing research on the epidemiology and characteristics of cancer patients is requested. This study explored the epidemiology of cancer, its characteristics, treatment patterns, and risk factors in the southern region of Saudi Arabia. Methods: A retrospective cross-sectional study was conducted using cancer patients’ medical records at Asir Central Hospital in the southern region of Saudi Arabia. Active patients’ records were extracted between January 2013 and December 2019. Results: A total of 2038 patients were identified during the study period, with a mean age of 60.9 (SD: 19.0) years. The patients had survived with their cancer for a median duration of 4 years (IQR: 2–6). Around 4.6% of the patients required ICU admission with a median period of 9 days (IQR: 5–14.75). The death rate during the study period was 10.9%. Around 20.8% of the cases were metastatic, of which 77.8% were at stage four of metastasis, and 19.7% of the patients were receiving chemotherapy for their disease. The most common types of cancer were malignant neoplasms of digestive organs, comprising 40.8% of the sample. Older age (60 years and above) and using specific chronic disease medications were predictors associated with a higher risk of death due to cancer (p < 0.05). Smoking history, using specific chronic disease medications, and having previous surgery were predictors associated with a higher risk of ICU admission (p < 0.05). Conclusion: Breast, colon, and liver cancers were the most prevalent in the southern region of Saudi Arabia. Several modifiable cancer risk factors were identified. The results of this study should support decision-makers in the initiation of programs for key modifiable risk factors that enhance lifestyle changes and reduce cancer risks
