Acute Limb Ischemia as a Concomitant Manifestation of COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus that causes multi-systemic manifestations identified as coronavirus disease 2019 (COVID-19). Respiratory tract symptoms are the most commonly seen in infected patients with COVID-19. Hypercoagulability state is the most common coagulopathy disorder associated with critically ill COVID-19 patients. Several inflammatory and coagulation factors such as D-dimers and fibrinogen correlate with the degree of pro-thrombotic state and burden of the disease. We describe a case of a 51-year-old man who presented with respiratory pneumonia and concomitant severe bilateral arterial thrombosis followed by right above knee amputation. 

A systematic review of contemporary evidence on SARS-CoV-2 and HIV coinfection: What does it look like up to date?

BACKGROUND

Preexisting alteration of the immune system by factors including older age, cardiovascular diseases, morbid obesity, diabetes, and chronic obstructive pulmonary disease (COPD) have detrimental effects on SARS-CoV-2 patients. Literature regarding SARS-CoV-2/human immunodeficiency virus (HIV) is still developing.

MATERIALS AND METHODS

We reviewed the existing literature pertaining to SARS-CoV-2/HIV coinfection systematically. Research records' characteristics and patients' clinical data were collected.

RESULTS

Seven research records were included, of which three were case series and four were case reports, reporting a total of 16 cases. There was one case of death, whereas (15/16) patients were discharged home. Majority of patients developed consistent clinical presentation of SARS-CoV-2. All patients had initial positive RT-PCR results, and four cases had HIV-related lymphopenia.

CONCLUSION

Although the current literature is still growing to increase our understanding of SARS-CoV-2/HIV coinfection, people living with HIV should adhere to the guidelines of healthy behavior and practice during this pandemic.

Quantitative and Qualitative Analysis of Medical Students' Research Output in Five Developing Countries

Objectives

The purpose of this analysis was to investigate the quantity and quality of medical students’ research output in Gulf Cooperation Council countries to aid in developing strategies to improve research output.

Methods

Abstracts presented by medical students in Gulf Cooperation Council countries were subject to analysis. Abstracts that propagated into full-length articles underwent further demographic analysis, in which data regarding the type of study, the field of study, country of origin, mode of presentation, and journal’s impact factor were collected. A total of 798 abstracts were surveyed, with 19% (n=155) of the abstracts submitted by Gulf Cooperation Council countries progressing into full-length publications. The average impact factor for Gulf Cooperation Council country publications was found to be 1.85 ± 0.26 (standard error). Countries that recorded the highest conversion rates were, in descending order, Kingdom of Saudi Arabia, United Arab Emirates, Oman, Bahrain, and Kuwait. Moreover, basic biomedical and clinical research topics were more likely to be published in comparison with community-oriented and medical education-related topics.

Conclusions

Effective efforts to encourage more medical student research output in the Gulf Cooperation Council countries (with a focus on qualitative analysis) should be promoted in order to achieve publication rates comparable with those reported by developed countries.

Medical Students' Perceptions of the Doctor-Patient Relationship: A Cross-Sectional Study from Saudi Arabia

Introduction The physician-patient relationship is at the heart of the art of medicine. Patient-centered care is rapidly evolving as the standard of care as well as the optimal vehicle to achieve high-quality healthcare and good clinical outcomes. This study aims to examine the attitudes of pre-clinical (third-year) students from Alfaisal University (Riyadh, Saudi Arabia) toward the physician-patient relationship. Methods This cross-sectional study took place during the spring 2017 academic year. All third-year students (n=210) were requested to voluntarily complete an online and anonymous questionnaire. The questionnaire covered students' demographical characteristics (gender, nationality, and cumulative grade point average) and their response to a previously validated instrument, the Patient-Practitioner Orientation Scale (PPOS), which explores the attitudes of medical students toward the doctor-patient relationship. Results In total, 132 students participated in the survey (n=132/210) with an overall response rate of 62.9%. Most respondents were female (56.8%), non-Saudi citizens (53.0%), and high achievers (70.5%). Most of the mean scores on the PPOS statements indicated patient-centered attitudes - that is, mean scores were higher than "3". The mean score for the overall PPOS was 4.0 ± 1.5, whereas the mean scores for the sharing and caring domains were 4.2 ± 1.5 and 3.8 ± 1.4, respectively. Univariate correlations between the students' demographics and their mean scores for the sharing domain, caring domain, and overall PPOS showed no statistically significant differences (p > 0.05). Conclusion The pre-clinical medical students showed favorable patient-centered attitudes. There were no statistically significant differences between students' demographics (gender, nationality, and academic performance) and PPOS scores (sharing domain, caring domain and overall score).

Dual-degree MBBS-MPH programs in Saudi Arabia: A call for implementation

Nowadays, any healthcare problem should be dealt with in a multidisciplinary approach that employs not only treating the symptoms of the problem but also its source. This simply implies the necessity to produce well-rounded medical graduates (physicians) who can competently integrate clinical knowledge/skills (for disease treatment) and public health knowledge/skills (for disease prevention). Moreover, the medical training (MD/MBBS curriculum) largely gives emphasis to the clinical skills needed to treat individual patients, whereas public health training (MPH degree) emphasizes the methods needed to improve the overall community health. Bridging the gap between patients and community is best achieved through a combined multidisciplinary training in both medicine and public health, that is, dual-degree MBBS-MPH programs are the way forward. In United States, for example, there are >80 medical schools that offer such joint MD-MPH programs, whereas there is none in Saudi Arabia. Herein, I call on higher education bodies to implement dual-degree MBBS-MPH programs in Saudi Arabia. To the best of knowledge, this is the first ever report to call for such an innovative implementation. Also, this short communication briefly sheds light on background, rationale, benefits, curriculum design, and future directions of such programs. The implications of this perspective (i.e. dual-degree MBBS-MPH programs) should not be limited to Saudi Arabia only; rather, it should be contemplated by the other medical curricula in the different countries.

Assessment of Consistency between Claims and References Referred to in Pharmaceutical Advertising Brochures in the Kingdom of Saudi Arabia

Drug advertisement brochures (DABs) contain claims that are often supplemented by references in medical literature. Several studies have evaluated the DABs as they are commonly distributed by drug companies to practicing physicians. The objective of this study is to assess the consistency between the claims and references referred to in the DABs in Saudi Arabia. DABs were collected from medical practitioners in Riyadh, Saudi Arabia. Authors developed a protocol to be followed for quality assessment of the DABs. The vast majority of cited scientific papers were indexed in PubMed. Consequently, each reference was categorized as: justifiable, false, exaggerated or ambiguous. A total of 89 DABs were collected; 48 (53.9%) brochures were excluded from further analysis and the remaining 41 brochures (46.1%) contained 240 references with an approximate average of 5.9 references per DAB. A total of 201 cited papers were traced (83.8%). The majority of references (93.0%) supported the claims for which they were cited. However, 1.5%, 4.0% and 1.5% of claims were deemed inaccurate/false, exaggerated, and ambiguous, respectively. This study supports that the majority of the claims made in the DABs of pharmaceutical companies in Saudi Arabia were unreferenced. However, most of the evidence presented to substantiate claims made was considered true.

Interest and perceived barriers toward careers in academic medicine among medical students at Alfaisal University - College of Medicine: A Saudi Arabian perspective

AIMS

[1] Identify the percentage of undergraduate students who are interested in academic medicine (AM) careers, [2] Explore the relationship between students' characteristics, previous experiences and interest in AM careers and [3] Determine students' perceived barriers toward AM careers at Alfaisal University - College of Medicine.

METHODS

An online, anonymous, random, self-rating survey was administered during spring 2013-2014 to second-year and third-year students (n = 302). Chi-square test was used to correlate between interest in AM careers and students' characteristics. Mann-Whitney U-test was used to compare the mean 5-point Likert scale responses between male and female students.

RESULTS

A total of 231 students participated in the survey (response rate: 76.5%). A total of 32 students (13.9%) expressed interest in AM careers, and this percentage significantly differed by gender, academic year, interest in teaching and research and previous research experiences (p < 0.05). The top three barriers were "lower income" (77.5%), "competing pressures to fulfill clinical-teaching-research duties" (73.6%) and "lack of career advising" (69.7%). As opposed to males, females achieved higher statistically significant differences of means regarding: "competing pressures to fulfill clinical-teaching-research duties" (p < 0.001) and "lack of same-gender role models in AM careers" (p < 0.000).

CONCLUSIONS

AM careers were unpopular by students. Curricular, extracurricular and institutional measures should be implemented to rectify this dilemma.

Cancer stem cell as therapeutic target for melanoma treatment

Human malignant melanoma is a highly aggressive skin tumor that is characterized by its extraordinary heterogeneity, propensity for dissemination to distant organs and resistance to cytotoxic agents. Although chemo- and immune-based therapies have been evaluated in clinical trials, most of these therapeutics do not show significant benefit for patients with advanced disease. Treatment failure in melanoma patients is attributed mainly to the development of tumor heterogeneity resulting from the formation of genetically divergent subpopulations. These subpopulations are composed of cancer stem-like cells (CSCs) as a small fraction and non-cancer stem cells that form the majority of the tumor mass. In recent years, CSCs gained more attention and suggested as valuable experimental model system for tumor study. In melanoma, intratumoral heterogeneity, progression and drug resistance result from the unique characteristics of melanoma stem cells (MSCs). These MSCs are characterized by their distinct protein signature and tumor growth-driving pathways, whose activation is mediated by driver mutation-dependent signal. The molecular features of MSCs are either in a causal or consequential relationship to melanoma progression, drug resistance and relapse. Here, we review the current scientific evidence that supports CSC hypothesis and the validity of MSCs-dependent pathways and their key molecules as potential therapeutic target for melanoma treatment.

Hand Hygiene: Knowledge and Attitudes of Fourth-Year Clerkship Medical Students at Alfaisal University, College of Medicine, Riyadh, Saudi Arabia

Introduction: Little is known about the clerkship (clinical) medical students’ knowledge of hand hygiene as the single most important precautionary measure to reduce nosocomial healthcare-associated infections. The aim of this study is to explore the knowledge of, and attitudes towards, hand hygiene practices among fourth-year clerkship medical students at Alfaisal University, College of Medicine, Riyadh, Saudi Arabia.

Materials and Methods: A cross-sectional, paper-based, Yes/No formatted questionnaire was administered to explore the students’ knowledge of, and attitudes towards, hand hygiene practices. Data were decoded in Microsoft Excel sheet and presented as numbers and percentages.

Results: One hundred and eleven students (n=111/147) participated in the questionnaire (response rate: 76%). Although the majority of students had a fair knowledge of hand hygiene practices, a number of them had some misconceptions. Only 14% of students correctly agreed to the statement: "Traditional hand washing (water, plus regular soap) decreases the number of germs." Furthermore, only 32% of students correctly answered that "hand washing with a regular soap, instead of an antiseptic soap, is better in limiting the transmission of clostridium difficile infections". Almost all students (93%) agreed to the importance of hand hygiene education in medical curricula and its awareness in healthcare centers. Despite the importance of hand hygiene, only 13% of students reviewed the respective WHO and CDC guidelines before starting their clinical training in the teaching hospital.

Discussion: The students’ inadequate knowledge about hand hygiene needs to be enriched by well-structured curricular and extra-curricular programs as well as more positive attitudes by healthcare workers.
