Colchicine use might be associated with lower mortality in COVID-19 patients: A meta-analysis.

BACKGROUND: Colchicine was recently repurposed for the management of coronavirus disease 2019 (COVID-19). This rapid review and meta-analysis aimed to assess colchicine's impact on mortality outcomes in COVID-19 patients. MATERIALS AND METHODS: We systematically searched PubMed, EMBASE, Google Scholar since their inception till 25/03/2021 for observational or controlled studies that reported mortality as an outcome. The mortality odd ratios were generated with their corresponding 95% confidence intervals utilizing the random-effects model. RESULTS: Nine studies comprising 5522 patients met our inclusion criteria. Our meta-analysis revealed significantly lower mortality in the colchicine group (OR 0.35, 95% CI 0.25-0.48, I2 0%) compared with controls. A subgroup analysis limited to hospitalized patients (OR 0.35, 95% CI 0.25-0.50, I2 0%) revealed similarly lower mortality in the colchicine group. CONCLUSIONS: This meta-analysis suggests a mortality benefit with colchicine when used in the treatment of COVID-19 patients. The majority of included studies were observational; thus, the findings of this review need to be further supported by the results of ongoing trials.

Do the selection criteria of internal medicine residency program predict resident performance?

BACKGROUND: Well-performing physician reflects the success of the residency program in selecting the best candidates for training. This study aimed to evaluate the selection criteria, mainly the United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge (CK) results and applicants' status as international or locally trained applicants, used by the medical education department and the internal medicine residency program in Hamad Medical Corporation in Qatar to predict the residents' performance during their training. METHODS: A retrospective chart review was performed for three batches of graduates who started residency training in 2011, 2012, and 2013. Each group completed 4 years of training. The USMLE Step 2 CK status of the applicant, in-training exam (ITE) scores, formative evaluation scores, Arab Board written and clinical exams pass rate, and other indicators were analyzed. Statistical analysis included chi squares and independent t-test to identify associations. Multivariable analyses were conducted using logistic and linear regressions to test for adjusted associations. RESULTS: The study included 118 (81 international/37 locally trained applicants) internal medicine residents. The ITE score correlated positively with the USMLE Step 2 CK score (r = 0.621, r = 0.587, r = 0.576, r = 0.571, p < 0.001) over the 4 years of training and among the international compared with locally trained applicants (p < 0.001). The rate of passing part 1 and 2 written exam of the Arab Board was higher in international than in local applicants, whereas clinical Arab Board exam and formative evaluation were not associated with any criteria. CONCLUSIONS: Higher USMLE Step 2 CK score correlated with better performance on ITE but not with other performance indicators, whereas international applicants did better in both ITE and Arab Board written exam than local applicants. These variables may provide reasonable predictors of well-performing physicians.

Asthma knowledge, care, and outcome during pregnancy: The QAKCOP study.

Asthma is the most common chronic medical condition affecting pregnancy. Optimizing asthma management in pregnancy is paramount for the well-being of both the mother and the baby. The primary objectives of this study were to assess patient's knowledge about asthma, the level of asthma care, and fetal and maternal outcomes among pregnant asthmatic women in this wealthy country with tremendous improvement in maternal and fetal health care. The secondary objective was to identify barriers to asthma control. This was a cross-sectional, face-to-face, prospective study of 80 pregnant women with physician-diagnosed asthma. About 56% of patients reported worsening of their asthma control during pregnancy, of which 52.3% felt this worsening in the third trimester. About 65% of patients had uncontrolled asthma during their pregnancy, and inhaler technique was incorrect in 64.4%. Only 38% of patients knew the difference between controller and reliever asthma medications, 12.7% of patients had received written asthma action plan, 17% had a spirometry done in the previous 5 years, and 3.8% had peak expiratory flow meter at home. The main reasons for uncontrolled asthma were lack of knowledge about right asthma medications in 30% and fear of side effects of inhaled corticosteroids in 19% of patients. No financial reason was reported. Significant associations between total number of pregnancies, poor perception of asthma medications, asthma exacerbation during delivery and poor asthma control were observed. Preeclampsia and congenital anomalies occurred at higher rates than previously reported among general population in this country. The tremendous improvements in maternal health care and socioeconomic status do not seem to be a barrier to the globally recognized poor asthma care in pregnancy. Important strategies are much needed.

An investigation into the avoidability of drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rising morbidity amongst hospitalized patients. Whilst clinical protocols for the management of individual DRESS cases have been well established, determination of potential prevention of these cases by utilizing novel "avoidability" tools has remained unexplored. This retrospective study reviewed records of patients who presented to the emergency department of Weill Cornell Medicine-affiliated Hamad General Hospital, Doha Qatar with suspected DRESS syndrome. These cases were independently adjudicated (utilizing the RegiSCAR, and JSCAR tools) as DRESS-drug pairs by a team of two clinical pharmacists and two General Physicians. They were then rated for potential avoidability with the Liverpool adverse drug reactions avoidability tool (LAAT) by the same team of raters. A total of 16 patients satisfied RegiSCAR criteria for DRESS syndrome. The mean age of the study population was 41.5 years (SD ± 13.3). The study population was predominantly male (n = 12; [75%]). The median latent period from drug ingestion to clinical presentation was 14 days (interquartile range [IQR] 6.5, 29). The median RegiSCAR and J-SCAR scores were 6 (IQR 5, 6.8), 5 (IQR 4, 5.8) respectively. Utilizing the LAAT, about 60% of the DRESS syndrome-drug pairs were rated as "avoidable" ("probable" or "definite"). The overall Krippendorf's alpha with the LAAT was 0.81 (SE 0.10, CI 0.59-1.00); with an intraclass correlation coefficient (ICC) of 0.90 (CI 0.77, 0.96.). In a randomly selected cohort of DRESS syndrome-drug pairs, a significant proportion was potentially avoidable ("possibly" and "definitely") utilizing the LAAT. This will need validation by larger sample-sized prospective studies utilizing the updated LAAT proposed by this study.

Perceived Barriers of Incident Reporting Among Internists: Results from Hamad Medical Corporation in Qatar.

Background Adverse events (AE) are responsible for annual deaths that exceed deaths due to motor vehicle accidents, breast cancer, and AIDS. Many AE are considered preventable. Thus, AE needs to be detected and analyzed. Incident reporting systems (IRS) are crucial in identifying AE. Nevertheless, the incident report (IR) process is flawed with underreporting, especially from the physicians' side. This limits its efficiency in detecting AE. Therefore, we aimed to assess the practice and identify the barriers associated with incident reporting among internal medicine physicians in a large tertiary hospital through a survey. Methods A cross-sectional descriptive study. We distributed an online survey to physicians working in the Internal Medicine Department of Qatar's largest tertiary academic institute. The questionnaire was validated and piloted ahead of the start of the trial. The response rate was 53%. Results A total of 115 physicians completed the survey; 59% acknowledged the availability of an institutional IRS. However, only 29% knew how to submit an online IR, and 20% have ever submitted an IR. The survey revealed that participants were less likely to submit an IR when they or a colleague is involved in the incident; 46% and 63%, respectively. The main barriers of reporting incidents were unawareness about the IRS (36%) and the perception that IR will not bring a system change (13%); moreover, there exists the fear of retaliation (13%). When asked about solutions, 57% recommended training and awareness, and 22% recommended sharing learnings and actions from previous IR. Conclusions IRS is underutilized by internal medicine physicians. The main barrier at the time of the survey is the lack of training and awareness. Promoting awareness and sharing previous learning and actions may improve the utilization of the IRS.

Breast Cancer Screening Practices in a Tertiary Care Center in the State of Qatar: A Cross-Sectional Survey.

INTRODUCTION: Breast cancer is the most common cancer in females. In Qatar, mortality related to breast cancer came in third after lung cancer and leukemia. In this study, we aim to comprehensively evaluate the rate of internal medicine residents and faculty compliance with breast cancer screening in Hamad Medical Corporation (Doha, Qatar), as well as to identify barriers and facilitators that could potentially augment changes to enhance physician-led cancer screening. METHODS: A cross-sectional web-based survey was distributed among internal medicine physicians between December 2018 and March 2019 at a tertiary medical centre. It focused on the knowledge, attitude, and practice of physicians regarding breast cancer screening guidelines and explored potential barriers and proposed solutions. Chi-square and t-test statistics were used to draw conclusions where appropriate. RESULTS: A total of 158 physicians responded to the survey, with a response rate of 61%. 75.9% were postgraduate trainees. Around three-quarters of the physicians mentioned that they would recommend breast cancer screening for their age-appropriate average-risk patients. There was a statistically significant difference between the trainees, consultants, and specialists regarding the modality of choice, where the majority of the trainees opted mammogram every 2 or 3 years while 44.4% of the consultants indicated yearly self-breast exam (p<0.001). The percentage of survey participants who rarely to never offer breast cancer screening in the outpatient settings was 37.8%. Unclear pathway (40%) and lack of time in clinic/ward rounds (26.5%) were the major reported barriers for cancer screening. CONCLUSION: In the current era of personalized medicine, physicians should be more oriented to local guidelines to provide optimal care to their patients. While the attitude towards breast cancer screening is positive, the overall compliance with the national recommendations is sub-optimal. Further initiatives and intervention programs are required to promote the breast cancer screening in Qatar.

Postpartum Pulmonary Hypertension Masquerading as Submassive Pulmonary Embolism: A Case Report and a Literature Review.

Postpartum pulmonary hypertension (PPPHT) is an extremely rare disorder, with few reported cases. Late diagnosis and treatment are associated with significant morbidity and mortality. We present an 18-year-old female patient who presented four-week postpartum with a typical submissive pulmonary embolism picture subsequently diagnosed as postpartum pulmonary hypertension. The patient had an excellent response to treatment, with a dramatic improvement in her functional status. The authors aim to urge physicians to keep this rare disorder in mind as timely and accurate diagnosis is crucial for management-additionally, the importance of counseling patients about the imminent risks associated with planned future pregnancies.

Knowledge, Attitude and Practice of Physicians Regarding Screening of Colorectal Cancer in Qatar: A Cross-Sectional Survey.

PURPOSE: The aim of this study was to evaluate the rate of internal medicine residents' and faculties' (specialists and consultants) compliance to colorectal cancer screening in Hamad Medical Corporation (Doha, Qatar) and to identify barriers as well as facilitators that will assist in drawing up changes that would enhance physician-related cancer screening. METHODS: A cross-sectional web-based survey was distributed among internal medicine physicians at three component hospitals of Hamad Medical Corporation (HMC); focusing on knowledge and practice of colorectal cancer screening, its barriers and facilitators. Chi-square and t-test statistics were used to draw conclusions where appropriate. RESULTS: The response rate for the survey was 91% and over 75% of the survey respondents were post-graduate trainees. The majority (90.6%) of the physicians (n=144) mentioned that they would recommend colorectal cancer screening for their asymptomatic patients, though trainees tend to choose the correct modality of screening compared to the consultants, 86.21% vs 40.74%. Only 43.4% of the survey participants always to usually recommend screening to their patients in their clinics while only 29.4% do so for their inpatients. Even though there was no statistically significant difference among the frequency of outpatient colorectal cancer screening among trainees, specialists or consultants (p=0.628), there was a clear increase in the reported referrals as the training years or the years of experience increases (p=0.049 for trainees and p=0.009 for faculty). Unclear pathway was reported as the main obstacle to outpatient cancer screening by 30.2% (n= 48) and 54% (n=87) pointed out that an easy and clear pathway for cancer screening would facilitate the same. CONCLUSION: While the attitude towards colorectal cancer screening is positive, the actual practice of recommendation is sub-optimal. Further initiatives are required to facilitate awareness and compliance to colorectal cancer screening.

Frequency of Abnormalities Detected by Point-of-Care Lung Ultrasound in Symptomatic COVID-19 Patients: Systematic Review and Meta-Analysis.

The COVID-19 pandemic has resulted in significant morbidity, mortality, and strained healthcare systems worldwide. Thus, a search for modalities that can expedite and improve the diagnosis and management of this entity is underway. Recent data suggested the utility of lung ultrasound (LUS) in the diagnosis of COVID-19 by detecting an interstitial pattern (B-pattern). Hence, we aimed to pool the proportion of various reported lung abnormalities detected by LUS in symptomatic COVID-19 patients. We conducted a systematic review (PubMed, MEDLINE, and EMBASE until April 25, 2020) and a proportion meta-analysis. We included seven studies examining the role of LUS in 122 COVID-19 patients. The pooled proportion (PP) of B-pattern detected by lung ultrasound (US) was 0.97 (95% CI: 0.94-1.00 I 2 0%, Q 4.6). The PP of finding pleural line abnormalities was 0.70 (95% CI: 0.13-1.00 I 2 96%, Q 103.9), of pleural thickening was 0.54 (95% 0.11-0.95 I 2 93%, Q 61.1), of subpleural or pulmonary consolidation was 0.39 (95% CI: 0.21-0.58 I 2 72%, Q 17.8), and of pleural effusion was 0.14 (95% CI: 0.00-0.37 I 2 93%, Q 27.3). Our meta-analysis revealed that almost all SARS-CoV-2-infected patients have abnormal lung US. The most common abnormality is interstitial involvement depicted as B-pattern. The finding from our review highlights the potential role of this modality in the triage, diagnosis, and follow-up of COVID-19 patients. A sizable diagnostic accuracy study comparing LUS, computed tomography scan, and COVID-19-specific tests is warranted to further test this finding and to delineate the diagnostic and prognostic yield of each of these modalities.

Prevalence of Venous Thromboembolism in Critically Ill COVID-19 Patients: Systematic Review and Meta-Analysis.

Background: Recent studies revealed a high prevalence of venous thromboembolism (VTE) events in coronavirus disease 2019 (COVID-19) patients, especially in those who are critically ill. Available studies report varying prevalence rates. Hence, the exact prevalence remains uncertain. Moreover, there is an ongoing debate regarding the appropriate dosage of thromboprophylaxis. Methods: We performed a systematic review and proportion meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed and EMBASE for studies exploring the prevalence of VTE in critically ill COVID-19 patients till 25/07/2020. We pooled the proportion of VTE. Additionally, in a subgroup analysis, we pooled VTE events detected by systematic screening. Finally, in an exploratory analysis, we compared the odds of VTE in patients on prophylactic compared with therapeutic anticoagulation. Results: The review comprised 24 studies and over 2,500 patients. The pooled proportion of VTE prevalence was 0.31 [95% confidence interval (CI) 0.24, 0.39; I 2 94%], of VTE utilizing systematic screening was 0.48 (95% CI 0.33, 0.63; I 2 91%), of deep venous thrombosis was 0.23 (95% CI 0.14, 0.32; I 2 96%), and of pulmonary embolism was 0.14 (95% CI 0.09, 0.20; I 2 90%). Exploratory analysis of few studies, utilizing systematic screening, VTE risk increased significantly with prophylactic, compared with therapeutic anticoagulation [odds ratio (OR) 5.45; 95% CI 1.90, 15.57; I 2 0%]. Discussion: Our review revealed a high prevalence of VTE in critically ill COVID-19 patients. Almost 50% of patients had VTE detected by systematic screening. Higher thromboprophylaxis dosages may reduce VTE burden in this patient's cohort compared with standard prophylactic anticoagulation; however, this is to be ascertained by ongoing randomized controlled trials.

Comparative effectiveness and safety of direct-acting oral anticoagulants (DOACS) for the reduction of recurrent venous thromboembolism in cancer patients: A protocol for systematic review and network meta-analysis using a generalized pairwise modeling methodology.

BACKGROUND: There has been a significant improvement in both our understanding and therapeutic choices available to clinicians for the management of cancer associated thrombosis (CAT). Even with the recent publication of a systematic review and landmark trials demonstrating the non-inferiority of DOACS-based anticoagulation strategy compared to the standard of care in patients with CAT, there is unresolved uncertainty regarding the exact hierarchy of risks and effectiveness of various DOAC analogues in these cohorts of patients. METHOD: We will carry out a network meta-analyses, utilizing a novel generalized pairwise methodology to generate direct and indirect comparisons between the various DOAC analogues. We will search the following databases for studies that satisfies pre-specified inclusions criteria; these include PubMed, EMBASE, Cochrane library, Clinicaltrials.gov, conference abstracts among other sources. The primary efficacy and safety outcomes are recurrent VTE and major hemorrhagic events, respectively. Two reviewers will Search the databases independently with the view to identify studies that meet eligibility criteria. The methodological quality of the included studies will be determined using a recently validated risk of bias assessment tool. RESULTS: We expect that the result of this review will ascertain the hierarchy of risks and effectiveness of various DOAC analogues in patients with CAT. CONCLUSION: Results of this review will assist in informed decisions making regarding therapeutic guidelines of DOAC in CAT.

An investigation into the avoidability of adverse drug reactions using the LAAT and modified Hallas tools.

An adverse drug reactions avoidability tool called the Liverpool ADR avoidability assessment tool (LAAT) was recently developed (for research purposes), and subsequently validated with mixed interrater reliability (IRR). We investigated the comparative IRR of this tool in an inpatient cohort to ascertain its practical application in this setting.The patient population was comprised of 44 ADR drug pairs drawn from an observational prospective cohort of patents with ADR attending a Weill Cornell Medicine-affiliated tertiary medical Centre in Doha Qatar (Hamad General Hospital). Using the LAAT, and modified Hallas tools, 4 independent raters (2 Clinical Pharmacologists, and 2 General Physicians) assessed and scored the 44 ADR-drug pairs. Agreement proportions between the rating pairs were evaluated as well individual/overall kappa statistics and intraclass correlation coefficients. We evaluated the weight of each of the 7 questions on the LAAT tool to ascertain its determinative role.Across 44 ADR-drug pairs, the overall median Fleiss kappa using the LAAT, and modified Hallas tools were 0.67 (interquartile range (IQR) 0.55, 0.76), 0.36 (IQR, 0.23-0.71) respectively. The overall percentage pairwise agreement with the LAAT and modified Hallas tools were 78.5%, and 62.2% respectively. Exact pairwise agreement occurred in 37 out of 44 (range 0.71-1), and 27 of 44 (0.53-0.77) ADR-drug pairs using the LAAT and modified Hallas tools respectively. Using the LAAT tool, the overall intraclass correlation coefficient was 0.68 (CI 0.55, 0.79), and 0.37 (CI 0.22, 0.53) with the modified Hallas tool.We report a higher proportion of "possible" and "definite" avoidability outcomes of adverse drug reactions compared with the modified Hallas, or that reported by developers of the LAAT tool. Although initially developed for research purposes, our report has suggested for the first time a potential applicability of this tool in clinical environment as well.

Fungal Malignant Otitis Externa Involves a Cascade of Complications Culminating in Pseudoaneurysm of Internal Maxillary Artery: A Case Report.

BACKGROUND Pseudomonal infection is the most common cause of malignant otitis externa (MOE), which typically affects elderly diabetic patients. Fungi are a rare cause of MOE. MOE can be life-threatening if not recognized and treated promptly. It can result in a wide spectrum of complications, including skull-base osteomyelitis, cranial nerve palsy, cerebral venous thrombosis, and brain abscess. Pseudoaneurysm formation of the intracranial vessels is a life-threatening complication of MOE that is seldom reported in the literature. CASE REPORT We report the case of a 66-year-old diabetic man with MOE who was initially treated with antipseudomonal antibiotics after negative initial culture results. His MOE resulted in a cascade of complications, including facial nerve palsy, skull base osteomyelitis, and sigmoid sinus thrombosis, and culminated in left maxillary artery pseudoaneurysm formation resulting in massive epistaxis and hemodynamic instability. Endovascular embolization resulted in a successful obliteration of the pseudoaneurysm. A subsequent functional endoscopic sinus surgical (FESS) tissue biopsy confirmed Candida glabrata as the etiological agent. The patient was successfully treated with antibiotics and antifungal and anticoagulation therapy, and was discharged home in good condition. CONCLUSIONS A high index of suspicion for the diagnosis of fungal MOE, particularly in intractable cases of MOE with negative initial cultures, should be maintained. Pseudoaneurysm formation is a life-threatening complication of MOE that is seldom reported in the literature and should be suspected in any patient with MOE who presents with epistaxis or intracranial bleeding.

Polymorphisms of tenofovir disoproxil fumarate transporters and risk of kidney tubular dysfunction in HIV-positive patients: genetics of tenofovir transporters.

The association between single nucleotide polymorphisms of genes encoding transport proteins involved in the bio-disposition of tenofovir disoproxil fumarate (TDF) and kidney tubular dysfunction (KTD) in HIV-positive patients was examined in this study. Fifty-eight patients who received TDF were screened for KTD using retinol-binding protein (RBP) concentration in urine. We defined KTD as the top quartile of urinary RBP/creatinine ratio (>17 µg/mmol), regardless of estimated glomerular filtration rate (eGFR) or proteinuria. Genotyping of genes encoding transport proteins involved in the disposition of TDF was undertaken using validated Taqman 5' nuclease assays. Patients with KTD (N = 15) had higher current CD4 cell counts, lower eGFR and were less likely to possess the genotype CC at position 24 of the ABBC2 (MRP2, rs717620) gene. In multivariate analysis, genotype CC at position 24 of the ABBC2 gene was significantly associated with KTD (odds ratio =0.05, 95% confidence interval = 0.003-0.7, P = 0.027). Genotype CC at position 24 of the ABBC2 (MRP2 rs717620) gene was significantly associated with a reduced risk of elevated urinary RBP in HIV-positive patients exposed to TDF.

Portomesenteric Thrombosis Secondary to Acute Cholecystitis: A Case Report.

Portomesenteric venous thrombosis (PMVT) is an uncommon clinical problem. Common risk factors include intra-abdominal infections, abdominal surgeries, malignancy, cirrhosis, and inherited thrombophilia. Early recognition and treatment of PMVT are important to avoid serious complications like mesenteric ischemia and infarction. Acute cholecystitis is a clinical condition encountered daily but rarely may be complicated by development of portomesenteric venous thrombosis. Only few cases have been reported of superior mesenteric vein thrombosis secondary to cholecystitis. We report a case of a forty-one-year-old male patient who developed partial portal and superior mesenteric vein thrombosis after mild acute cholecystitis for which surgery had been deferred. Patient had no other identifiable risk factors for thrombosis. Patient was successfully treated with 6 months of anticoagulation with warfarin and complete recanalization of portomesenteric veins was achieved at the end of treatment.

Establishment of a Sentinel Laboratory-Based Antimicrobial Resistance Surveillance Network in Ethiopia.

In 2014, as part of the Global Health Security Agenda, Ethiopia was provided the technical and financial resources needed to prioritize antimicrobial resistance (AMR) in the national public health sphere. Under the direction of a multi-stakeholder working group, AMR surveillance was launched in July 2017 at 4 sentinel sites across the country. The AMR surveillance initiative in Ethiopia represents one of the first systematic efforts to prospectively collect, analyze, and report national-level microbiology results from a network of hospitals and public health laboratories in the country. Baseline readiness assessments were conducted to identify potential challenges to implementation to be addressed through capacity-building efforts. As part of these efforts, the working group leveraged existing resources, initiated laboratory capacity building through mentorship, and established infrastructure and systems for quality assurance, data management, and improved coordination. As a result, AMR surveillance data are being reported and analyzed for use; data from more than 1,700 patients were collected between July 2017 and March 2018. The critical challenges and effective solutions identified through surveillance planning and implementation have provided lessons to help guide successful AMR surveillance in other settings. Ultimately, the surveillance infrastructure, laboratory expertise, and communication frameworks built specifically for AMR surveillance in Ethiopia can be extended for use with other infectious diseases and potential public health emergencies. Thus, building AMR surveillance in Ethiopia has illustrated how laying the foundation for a specific public health initiative can develop capacity for core public health functions with potential benefit.
