RESUMO

OBJECTIVES: To compare the safety and efficacy between high dose and low dose oxytocin administration for labor augmentation. METHODS: We searched for the available studies during March 2020 in PubMed, Cochrane Library, Scopus, and ISI Web of science. All randomized clinical trials (RCTs) that assessed safety and efficacy of high dose vs. low dose oxytocin for labor augmentation were considered. The extracted data were entered into RevMan software. Dichotomous and continuous data were pooled as odds ratio (OR) and mean difference (MD) respectively, with the corresponding 95% confidence intervals (CI). Our main outcomes were cesarean delivery rate, spontaneous vaginal delivery rate, uterine hyperstimulation and tachysystole, and labor duration from oxytocin infusion. RESULTS: Eight RCTs with 3,154 patients were included. High dose oxytocin did not reduce cesarean delivery rate compared to low dose oxytocin (OR=0.76, 95% CI [0.52, 1.10], p=0.15). After solving the reported heterogeneity, high dose oxytocin did not increase the rate of spontaneous vaginal deliveries vs. low dose oxytocin (OR=1.06, 95% CI [0.84, 1.32], p=0.64). Low dose oxytocin was linked to a significant decline in uterine hyperstimulation and tachysystole (p>0.001). A reduction in labor duration was found in high dose oxytocin group over low oxytocin regimen (MD=-1.02 h, 95% CI [-1.77, -0.27], p=0.008). CONCLUSIONS: We found no advantages for high dose oxytocin over low dose oxytocin in labor augmentation except in reducing labor duration. Low dose oxytocin is safer as it decreases the incidence of uterine hyperstimulation and tachysystole. More trials are needed to confirm our findings.

RESUMO

This study aimed to compile all the relevant studies of patients presenting with pericardial tamponade before or after diagnosis of lymphoma, describe the clinical presentations of patients with lymphoma and cardiac tamponade, and assess the difference in overall survival based on the timing of cardiac tamponade diagnosis. A comprehensive search strategy was conducted in the following databases: PubMed and Cochrane Library, using the following keywords: Lymphoma AND Cardiac Tamponade. The criteria for eligibility included cases with a confirmed diagnosis of lymphoma and cardiac tamponade, human studies, and publications in English language. The statistical analysis was performed using IBM Statistical Package for Social Sciences (SPSS) version 20. We included 48 research articles (n = 52 cases) with adequate reporting of measured outcomes. The median age of the patients was 52 (9-94) years. Only 6 patients were noted to have primary cardiac lymphoma, while the majority of cases were considered to have secondary cardiac lymphoma (88.5%). According to the data on the type of lymphoma reported through cytology and immunohistochemistry, 49 patients were diagnosed with non-Hodgkin lymphoma, and of these cases the most common subtype was large B-cell lymphoma (42.9%). Overall, the average duration of illness was 14 ± 23 days. A total of 13 patients had distant heart sounds, 12 cases were noted to be hypotensive, and 13 subjects were found to have increased jugular venous pressure. Our retrospective study demonstrated that most patients presented with pericardial tamponade after lymphoma diagnosis, and those were mostly secondary cardiac lymphoma of the non-Hodgkin type with large B-cell as the most common subtype. Dyspnoea, oedema, and constitutional symptoms were the most common presenting signs. The median overall survival of patients with lymphoma and cardiac tamponade is 4 months, with no significant difference in mortality in the presentation timing before and after the diagnosis of lymphoma.

RESUMO

INTRODUCTION: Many pharmaceutical, surgical, and complementary medical interventions are used for primary dysmenorrhea treatment. However, no consensus has been reached about the most effective intervention. OBJECTIVE: To compare the efficacy and safety of IV tramadol versus IV paracetamol in relieving acute pain of primary dysmenorrhea. METHODS: This randomized controlled trial was conducted in a tertiary referral hospital and included 100 patients between 18 and 35 years old diagnosed with primary dysmenorrhea. Patients received either 1-g paracetamol or 100-mg tramadol in 100-mL normal saline as an IV infusion over 10 min. Pain intensity was measured by using a visual analog scale at 15, 30, 60 min, and 2 h. We recorded drug side effects and requirements for rescue analgesics. RESULTS: Pain scores were significantly lower in the tramadol group compared with the paracetamol group at 15, 30, 60 min, and 2 h (p < 0.001). Fewer patients in the tramadol group needed rescue analgesics compared with the paracetamol group (p = 0.04). No significant differences were reported in side effects between both groups. CONCLUSIONS: IV tramadol is superior to IV paracetamol in relieving acute pain of primary dysmenorrhea with a comparable side effect profile.

RESUMO

Non-alcoholic fatty liver disease is the most rapidly growing form of liver disease and if left untreated can result in non-alcoholic steatohepatitis, ultimately resulting in liver cirrhosis and failure. Biliverdin reductase A (BVRA) is a multifunctioning protein primarily responsible for the reduction of biliverdin to bilirubin. Also, BVRA functions as a kinase and transcription factor, regulating several cellular functions. We report here that liver BVRA protects against hepatic steatosis by inhibiting glycogen synthase kinase 3ß (GSK3ß) by enhancing serine 9 phosphorylation, which inhibits its activity. We show that GSK3ß phosphorylates serine 73 (Ser(P)73) of the peroxisome proliferator-activated receptor α (PPARα), which in turn increased ubiquitination and protein turnover, as well as decreased activity. Interestingly, liver-specific BVRA KO mice had increased GSK3ß activity and Ser(P)73 of PPARα, which resulted in decreased PPARα protein and activity. Furthermore, the liver-specific BVRA KO mice exhibited increased plasma glucose and insulin levels and decreased glycogen storage, which may be due to the manifestation of hepatic steatosis observed in the mice. These findings reveal a novel BVRA-GSKß-PPARα axis that regulates hepatic lipid metabolism and may provide unique targets for the treatment of non-alcoholic fatty liver disease.

RESUMO

Engaging medical students in scholarly research activities and producing clinically competent and research-oriented medical workforces are essential demands, particularly in developing countries. Dual-degree MD-PhD programs offer simultaneous rigorous education in medicine and research, and train its graduates (physician-scientists) to successfully catalyze translational research evolutions. Literature fundamentally identifies dual-degree MD-PhD programs as the single most important, well-established, popular and influential programs toward commencing physician-scientist professions. While the physician-scientist population is alarmingly vanishing in the West with ongoing efforts to reverse this undesired trend, such population is largely nonexisting, unfortunately to start with, in Saudi Arabia. This is simply because no single dual-degree MBBS-PhD program is yet established in Saudi Arabia. Herein, we call on the Saudi Higher Education bodies to implement dual-degree MBBS-PhD programs with anticipated generation of competent physician-scientists in Saudi Arabia. To the best of our knowledge, this is the first ever report to call for such innovative implementation.

RESUMO

Team-based learning (TBL) is an emerging teaching and learning strategy being employed in medical schools. The College of Medicine at Alfaisal University has adopted a TBL approach as an instructional method for first-year medical students. The aim of the present study was to describe the TBL method employed at Alfaisal University College of Medicine and to assess first-year medical students' perceptions of this learning modality for the anatomy- and physiology-based blocks/courses in organ systems form of curriculum. A five-point Likert scale questionnaire was structured based on Kirkpatrick's theory and assessed three major domains: reaction, learning, and behavior. Confirmatory factor analysis (CFA) and Cronbach's α-coefficient tests were used to assess the validity and reliability of the construct, respectively. CFA showed an adequate validity of the survey and Cronbach's α revealed an acceptable internal uniformity (0.69). A total of 185 respondents rated reaction, learning, and behavior toward introduction of TBL as 3.53 ± 1.01, 3.59 ± 1.12, and 3.57 ± 1.12, respectively. Excellent students rated TBL highly in all major domains compared with borderline students (reaction, behavior, and learning domains with P values of <0.049, <0.035, and <0.031, respectively). Students who had prior teamwork experience rated TBL higher in terms of their learning experience compared with those who were rarely involved in team work. This study demonstrated that Alfaisal University first-year medical students perceived TBL positively as a teaching and learning strategy for functional anatomy, and prior involvement in teamwork and academic performance correlates with higher ratings of TBL.

RESUMO

Student contributions to research have been shown to effectively reflect on their communication and critical thinking skills. Short-term research courses offer opportunities for medical students to advance their research experience in subsequent high-demanding long-term research opportunities. The purpose of the present study was to describe the development, implementation, and evaluation of a research-oriented series (ROS) on undergraduate students at Alfaisal University in Saudi Arabia. The ROS was designed to comprise eight sessions. Each session addressed core principles and the practice of research concepts and was based on theoretical morning sessions supplemented by afternoon practical sessions delivered by experienced senior medical students and faculty members. Students were assessed comprehensively by the end of the ROS. The series was conducted twice, and 35 students were involved each time. A total of 70 enrolled students (35 men and 35 women) with grade point averages of >3.5 and <3.5 were asked to fill out an anonymous, online, self-administered questionnaire assessing their perception of knowledge, skills, and confidence after attending the ROS and evaluating their senior peers. Ninety percent of the medical students responded to the online survey and rated the ROS highly in improving their research knowledge, skills, and confidence. Male students reported significant gains compared with their female peers (P<0.05). Grade point averages did not play a role in student gains after attending the ROS. Qualitative responses were in support of three recurring themes favoring the unique learning environment in the ROS. In conclusion, the ROS offers a short-term systematic approach to fundamental steps and concepts of biomedical research.

RESUMO

BACKGROUND: The high academic performance of medical students greatly influences their professional competence in long term career. Meanwhile, medical students greatly demand procuring a good quality of life that can help them sustain their medical career. This study examines validity and reliability of the tool among preclinical students and testifies the influence of their scholastic performance along with gender and academic year on their quality of life. METHODS: A cross sectional study was conducted by distributing World Health Organization Quality of Life, WHOQOL-BREF, survey among medical students of year one to three at Alfaisal University. For validity, item discriminate validity(IDV) and confirmatory factor analysis were measured and for reliability, Cronbach's α test and internal item consistency(IIC) were examined. The association of GPA, gender and academic year with all major domains was drawn using Pearson's correlation, independent samples t-test and one-way ANOVA, respectively. RESULTS: A total of 335 preclinical students have responded to this questionnaire. The construct has demonstrated an adequate validity and good reliability. The high academic performance of students positively correlated with physical (r = 0.23, p < 0.001), psychological health (r = 0.29, p < 0.001), social relations (r = 0.11, p = 0.03) and environment (r = 0.23, p < 0.001). Male student scored higher than female peers in physical and psychological health. DISCUSSION: This study has identified a direct relationship between the academic performance of preclinical students and their quality of life. CONCLUSION: The WHOQOL-BREF is a valid and reliable tool among preclinical students and the positive direction of high academic performance with greater QOL suggests that academic achievers procure higher satisfaction and poor achievers need a special attention for the improvement of their quality of life.

RESUMO

INTRODUCTION: Concern has been expressed in recent times whether medical schools have adapted sufficiently to cater for the increasing demand of physician-scientists. Studies have shown that research involvement at the undergraduate level is vital to accommodate this growing need. Enhanced communication skills, improved problem-solving abilities and better future employment opportunities are among the other many benefits of undergraduate research (UR). Herein, we report projects run by a unique student driven undergraduate research committee (URC) at Alfaisal University, Riyadh, Saudi Arabia aimed at providing the future generation of physicians training opportunities for pursuing a research intensive career. METHODS: The article describes the unique structure of the URC and provides an in-depth description of the various programs and activities used in promoting students' research activities. We analyzed students' perception of URC activities via a questionnaire and analyzed research-output of the first graduating batches through their publication record. RESULTS: Overall, more than 60% of the graduating students were involved in the various research programs offered by the URC and around 50% published in peer-reviewed journals with an average impact factor of 2.4. CONCLUSIONS: Research involvement by medical students is an essential need of the twenty-first century and models like URC could provide crucial platform for research training to the new generation of physician-scientists.

RESUMO

The freshman academic year is one of the most difficult years that a medical student experiences in his/her academic life at a medical school. Freshmen are frequently faced with several challenges, such as adaptation to a new academic environment and its associated different methods of teaching, learning, skills, and assessment. The aim of this study was to describe a 4-wk innovative summer premedical program developed by senior medical students at the College of Medicine, Alfaisal University, in an attempt to improve/smooth the experience(s) of prospective freshmen. This report describes the objectives/strategies/methodologies used to tackle the top three identified freshman challenges, namely, 1) advancement of the academic/scholastic/educational background, 2) the development of college-required skills to succeed and excel in the freshman year, and 3) adaption to the college environment. At the end of the program, a survey was conducted to evaluate the effectiveness of the summer premedical program. Seventy-two students attended this program over the past three summers from 2010 to 2012, and twenty-nine students answered the survey with a response rate of 74.1%. Overall, >90% of the survey respondents reported an improvement in their understanding of basic medical science, integration, presentation skills, medical terminology, and junior-senior relationships. Furthermore, the survey highlighted the need for more focus on skills such as time management, participation in large-group discussions, and use of electronic resources, as >50% of respondents reported no improvement in these areas. In conclusion, this is the first report, to our knowledge, that describes a program developed by senior medical students to improve the experience of freshmen.

RESUMO

Melanoma is the third most common type of skin cancer, characterized by its heterogeneity and propensity to metastasize to distant organs. Melanoma is a heterogeneous tumor, composed of genetically divergent subpopulations, including a small fraction of melanoma-initiating cancer stem-like cells (CSCs) and many non-cancer stem cells (non-CSCs). CSCs are characterized by their unique surface proteins associated with aberrant signaling pathways with a causal or consequential relationship with tumor progression, drug resistance, and recurrence. Melanomas also harbor significant alterations in functional genes (BRAF, CDKN2A, NRAS, TP53, and NF1). Of these, the most common are the BRAF and NRAS oncogenes, with 50% of melanomas demonstrating the BRAF mutation (BRAFV600E). While the successful targeting of BRAFV600E does improve overall survival, the long-term efficacy of available therapeutic options is limited due to adverse side effects and reduced clinical efficacy. Additionally, drug resistance develops rapidly via mechanisms involving fast feedback re-activation of MAPK signaling pathways. This article updates information relevant to the mechanisms of melanoma progression and resistance and particularly the mechanistic role of CSCs in melanoma progression, drug resistance, and recurrence.

RESUMO

OBJECTIVE: To compare letrozole in combination with gonadotropins versus letrozole monotherapy in ovulation induction and clinical pregnancy among infertile women with polycystic ovarian syndrome (PCOS). METHODS: Several databases were searched for available clinical trials from inception until March 2023. We selected randomized controlled trials (RCTs) that compared sequential letrozole/gonadotropin versus letrozole alone among infertile women who met the Rotterdam criteria for PCOS. RevMan software was used to perform our meta-analysis. Our primary outcomes were ovulation and clinical pregnancy rates. Our secondary outcomes were endometrial thickness, number of mature follicles (diameter ≥ 18 mm), and incidence of miscarriage and ovarian hyperstimulation syndrome (OHSS). RESULTS: Six RCTs were retrieved with a total number of 723 patients. The ovulation and clinical pregnancy rates were significantly higher among the letrozole/gonadotropin group versus the letrozole monotherapy group (p < 0.001). In addition, there were significant improvements in endometrial thickness and number of mature follicles in the letrozole/gonadotropin group. There were no significant differences between the two groups regarding incidence of miscarriage and ovarian hyperstimulation syndrome. CONCLUSION: Letrozole in combination with gonadotropin is superior to letrozole alone in improving ovulation induction and clinical pregnancy among PCOS patients. More trials are required to confirm our findings.

RESUMO

Melanoma frequently harbors genetic alterations in key molecules leading to the aberrant activation of PI3K and its downstream pathways. Although the role of PI3K/AKT/mTOR in melanoma progression and drug resistance is well documented, targeting the PI3K/AKT/mTOR pathway showed less efficiency in clinical trials than might have been expected, since the suppression of the PI3K/mTOR signaling pathway-induced feedback loops is mostly associated with the activation of compensatory pathways such as MAPK/MEK/ERK. Consequently, the development of intrinsic and acquired resistance can occur. As a solid tumor, melanoma is notorious for its heterogeneity. This can be expressed in the form of genetically divergent subpopulations including a small fraction of cancer stem-like cells (CSCs) and non-cancer stem cells (non-CSCs) that make the most of the tumor mass. Like other CSCs, melanoma stem-like cells (MSCs) are characterized by their unique cell surface proteins/stemness markers and aberrant signaling pathways. In addition to its function as a robust marker for stemness properties, CD133 is crucial for the maintenance of stemness properties and drug resistance. Herein, the role of CD133-dependent activation of PI3K/mTOR in the regulation of melanoma progression, drug resistance, and recurrence is reviewed.

RESUMO

Background: Cardiovascular diseases are higher in African American population, and in the past three decades, less decline in mortality was observed in African Americans compared with white Americans American health disparities resulted in establishing one of the largest single-site investigations to examine causes of cardiovascular diseases in African American population, namely the Jackson Heart Study (JHS). Methods: In January 2020, we used the jacksonheartstudy.org website to obtain the list of publications produced by the JHS from 1999 to 2018. The citation's frequency was obtained for 455 articles using the search engine "google.com". The top 20 cited articles were characterized based on the first author's name, the month and year of publication, and the journal's name and its impact factor. Results: The frequency of citations for the 20 most-cited articles in the Jackson heart study ranged from 282 to 5545. The average number of citations was 1045.60. The top 20 articles were represented in 8 different peer-reviewed journals. Conclusion: The top 20 cited articles in the JHS were in the genetics field and were all observational in type. Future direction of the JHS should be directed toward well established interventional studies.

RESUMO

This paper reports a systematic review and meta-analysis of the effectiveness of hyoscine-N-butylbromide (HBB) administration in hysterosalpingography (HSG). Four electronic databases were searched for randomised controlled trials (RCTs) that compared HBB versus placebo or no intervention in infertile women undergoing HSG. Pain during and after HSG and different adverse events including nausea, vomiting, and dizziness were evaluated. Three RCTs with 335 patients were included. The analysis showed HBB was significantly effective in reducing pain during and after HSG (MD = -0.76 mm, 95% CI [-1.35, -0.17], p = 0.01) and (MD = -0.81 mm, 95% CI [-1.07, -0.56], p < 0.001), respectively. There were no significant differences in adverse events between HBB and control groups. The methodological evidence quality was high as evaluated by GRADEpro. In conclusion, this review provides good evidence that prior administration of HBB is effective in reducing induced pain during and after HSG with tolerable side effects.

RESUMO

BACKGROUND: Determining the success of infectious disease outbreak prevention is dependent mainly on public knowledge and compliance regarding the guidelines of precautionary behaviors and practices. While the current literature about the COVID-19 pandemic extensively addresses clinical and laboratory-based studies, a gap remains still present in terms of evaluating the general public knowledge and behaviors towards the COVID-19 pandemic. The aim of this review was to form a preliminary and contemporary understanding of the general public knowledge, attitude, and behaviors towards the COVID-19 pandemic globally. METHODS: A systematic search was conducted in various databases until May 2020. Each study's characteristics including the sample size, region, and study type were examined individually. A meta-analysis with a random-effects model and pooled prevalence with 95% confidence interval (CI) of all evaluated outcomes such as adequate knowledge, positive feelings, worrisome about the COVID-19 pandemic, and practice were recorded and reported from each study. Parameters such as random distribution, blinding, incomplete outcome data, selective reporting, and other biases were utilized to assess the quality of each retrieved record. Both Begg's and Egger's tests were employed to evaluate symmetry of funnel plots for assessment of publication bias. The overall quality of evidence was evaluated using GRADEpro software. RESULTS: A total of 26 studies with 67,143 participants were analyzed. The overall prevalence of knowledge, positive attitude, worrisome, and practice of precautionary measures were 0.87 (95%CI, 0.84-0.89), 0.85 (95%CI, 0.77-0.92), 0.71 (95%CI, 0.61-0.81), and 0.77 (95%CI, 0.70-0.83), respectively. Subgroup analysis demonstrated that social distancing was less practiced in Africa than other regions (p = 0.02), while knowledge of prevention of COVID-19 was reported higher in Asia (p = 0.001). Furthermore, people in developing countries had a higher prevalence of worrisome towards the COVID-19 pandemic with a p-value of less than 0.001. The quality of evidence was noted to be of low certainty in practice domain but moderate in the remaining outcomes. CONCLUSION: Assessing the public's risk perception and precautionary behaviors is essential in directing future policy and health population research regarding infection control and preventing new airborne disease outbreaks.

RESUMO

Reactive oxygen species play crucial role in biological homeostasis and pathogenesis of human diseases including cancer. In this line, now it has become evident that ROS level/concentration is a major factor in the growth, progression and stemness of cancer cells. Moreover, cancer cells maintain a delicate balance between ROS and antioxidants to promote pathogenesis and clinical challenges via targeting a battery of signaling pathways converging to cancer hallmarks. Recent findings also entail the therapeutic importance of ROS for the better clinical outcomes in cancer patients as they induce apoptosis and autophagy. Moreover, poor clinical outcomes associated with cancer therapies are the major challenge and use of natural products have been vital in attenuation of these challenges due to their multitargeting potential with less adverse effects. In fact, most available drugs are derived from natural resources, either directly or indirectly and available evidence show the clinical importance of natural products in the management of various diseases, including cancer. ROS play a critical role in the anticancer actions of natural products, particularly phytochemicals. Benzophenanthridine alkaloids of the benzyl isoquinoline family of alkaloids, such as sanguinarine, possess several pharmacological properties and are thus being studied for the treatment of different human diseases, including cancer. In this article, we review recent findings, on how benzophenanthridine alkaloid-induced ROS play a critical role in the attenuation of pathological changes and stemness features associated with human cancers. In addition, we highlight the role of ROS in benzophenanthridine alkaloid-mediated activation of the signaling pathway associated with cancer cell apoptosis and autophagy.

RESUMO

Our objective was to assess and rank different pharmacological interventions for relieving endometriosis-related pain. We conducted an online bibliographic search in different databases from their inception until March 2019. We included randomized controlled trials (RCTs) that assessed different medical therapies in the management of endometriosis-related pain. We applied this network meta-analysis (NMA) based on the frequentist approach using statistical package "netmeta" (version 1.0-1) in R software. Our main outcomes were the change in severity of pelvic pain, dysmenorrhea score, non-menstrual pelvic pain score, and dyspareunia score. Overall, 36 RCTs were included in this study (patients no. = 7942). Dienogest (0.94), combined hormonal contraceptives (CHCs) (0.782), and elagolix (0.38) were the highest-ranked interventions for reducing the severity of pelvic pain at three months, while at six months, gonadotropin-releasing hormone (GnRH) analogues (0.75), levonorgestrel-releasing intrauterine system (LNG-IUS) (0.73), and dienogest (0.65) were linked to more reduction in pelvic pain. The ranking p-score showed that GnRH analogues was the highest-ranked treatment for reducing dysmenorrhea at 3 months (1.00), while CHCs were the highest-ranked treatment at 6 months (0.97), followed by GnRH analogues (0.89). GnRH analogues (0.63) and elagolix (0.54) at three months while desogestrel (0.94) and CHCs (0.91) at six months were the highest-ranked treatment to reduce non-menstrual pelvic pain. GnRH analogues and elagolix were the highest-ranked pharmacologic therapies for reducing dyspareunia. In conclusion, CHCs, GnRH analogues, progesterone, and elagolix were the best approaches in reducing the pain of endometriosis.
