RESUMO

BACKGROUND: Autoimmune rheumatic diseases (ARDs) are characterized by immune dysfunction and associated with an increased risk of infections, which were of significant concern during the coronavirus disease 2019 (COVID-19) pandemic. Variable rates of COVID-19 incidence have been reported in patients with ARDs; however, the true effect of this infection on this patient population is still unclear. We, therefore, aimed to evaluate the COVID-19 prevalence among a multiethnic cohort of patients with ARDs in Qatar. MATERIAL AND METHODS: We used telephonic surveys to collect demographic and clinical information of patients with ARD in Qatar between April 1 and July 31, 2020, including any close contact with a COVID-19 case at home or work and polymerase chain reaction (PCR)-confirmed COVID-19 diagnosis. An electronic medical records review was conducted to verify pertinent data collected through the surveys. Prevalence with 95% confidence interval (CI), Student's t-tests, and chi-square/Fisher's exact tests were used for univariate analyses, whereas multivariate logistic regression was used to identify factors associated with COVID-19. RESULTS: The study included 700 patients with ARD (mean age, 43.2 ± 12.3 years), and 73% were female. Until July 2020, 75 (11%, 95% CI 9%-13%) patients had COVID-19. Factors associated with COVID-19 included being a man (adjusted odds ratio [aOR] 2.56, 95% CI 1.35-4.88, p = 0.01) and having close contact with a COVID-19 case (aOR 27.89, 95% CI 14.85-52.38, p = 0.01). Disease severity and rheumatic medications had no significant association with the odds of contracting COVID-19. In the 86 patients with ARD having close contact, the frequency of hydroxychloroquine utilization was lower in patients who contracted COVID-19 than in those who did not (35% vs 72.5%, p = 0.01). CONCLUSIONS: In Qatar, patients with ARDs had an overall higher prevalence of COVID-19 than global estimates. Being male and having close contact with a COVID-19 case were strongly associated with COVID-19 as reported globally. The presence of comorbid conditions, disease-specific factors, and rheumatic medications had no significant effect on the risk of COVID-19 in our study suggesting alternative mechanisms to the increased prevalence.

RESUMO

Background: A single organ and tissue donor can serve and save eight-fold lives, but availability of organ donors is scarce, posing a grim situation for end-stage organ failure worldwide. Knowledge, attitudes, behaviors, and beliefs toward organ donation can help policymakers develop strategies to address the challenges facing organ donation and transplantation in Qatar. Aim: To assess sociodemographic characteristics, knowledge, attitudes, beliefs and intentions regarding organ donation in the household population of Qatar. Methods: A prospective observational household survey was conducted between October and November 2016 in Qatar using a validated questionnaire. One thousand forty-four individuals aged 18 and older residing in eight municipalities in the country were enrolled in the survey. Results: Average age was 38 ± 11 years. There were 27.4% Qatari citizens and 72.6% nonQatari residents in the survey. 48.9% of the total (1044) were males. Knowledge [46% (95% C.I.: 45% - 47%)], attitude [70% (95% C.I.: 66%-74%)], behavioral beliefs [42% (95% C.I.: 39%-50%)], normative beliefs [29% (95% C.I.: 28%-30%)], control beliefs [-27% (95% C.I.: - 24% to - 30%)] and intentions towards organ donation [29% (95% C.I.: 27%-31%)] were observed in the study. Factor analyses were able to explain 70%, 72%, 70%, and 74% variations in knowledge, attitude, beliefs, and intentions domains respectively showing adequacy of construct of the domains for organ donation. Conclusion: Most of the survey participants showed good attitude but less intention towards organ donation.

RESUMO

Introduction: Studies from the US and Europe showed a decline in smoking among patients with acute myocardial infarction (AMI), but limited data are available from the Middle East. In this study, we describe the temporal trend in the prevalence, associated risk factors, and outcomes of smoking among patients with AMI in Qatar. Materials and Methods: A total of 27,648 AMI patients were analyzed from the cardiology registry at Heart Hospital, Doha, Qatar. This spans from January 1991 to May 2022. Results: Of the total, 13,562 patients (49.1%, 95% confidence interval [CI]: 48%-50%) were smokers, with a clear majority of males (98.5%). Smoking habit was found to decrease in AMI patients with increasing age (age 51-60 years, adjusted odds ratio [OR]: 0.71, 95% CI: 0.67-0.76, P = 0.001, and age ≥61 years, adjusted OR: 0.45, 95% CI: 0.42-0.48, P = 0.001, in comparison to age ≤50 years). Smoking was associated with a lower risk of inhospital mortality (adjusted OR: 0.61, 95% CI: 0.54-0.70, P = 0.001), but triglyceride, obesity, and old myocardial infarction risk factors were associated with a higher risk. A decreasing trend in current smoking habits in each quantile of the 1996-2000 year (adjusted OR: 0.82, 95% CI: 0.71-0.93, P = 0.001), 2001-2005 year (adjusted OR: 0.70, 95% CI: 0.62-0.80, P = 0.001), 2006-2010 year (adjusted OR: 0.75, 95% CI: 0.67-0.84, P = 0.001), 2011-2015 year (adjusted OR: 0.48, 95% CI: 0.42-0.54, P = 0.001), 2016-2020 year (adjusted OR: 0.48, 95% CI: 0.43-0.54, P = 0.001), and ≥2021 year (adjusted OR: 0.46, 95% CI: 0.40-0.53, P = 0.001) was observed in comparison to the quantile 1991-1995 year. Similar results were also observed in the young population (age ≤50 years) including the non-Qataris, who had 25% more smokers in comparison to Qatari nationals. Conclusion: Smoking trended down significantly; however, it remained prevalent in 50% of patients among AMI patients. Smokers were younger, with fewer traditional risk factors, and had lower inhospital mortality.

RESUMO

INTRODUCTION: Colorectal cancer is one of the most common cancers globally. Recent reductions in mortality rates have been primarily attributed to screening programs. The State of Qatar established a national bowel cancer screening program in 2016. METHODOLOGY: Fecal immunochemical testing (FIT) was used for average-risk individuals aged 50 to 74 years. Fecal immunochemical testing -positive participants were referred for total colonoscopy to detect polyps and cancers. RESULTS: Among 32,751 FIT invitees, 11,130 took the test, and 758 (6%) of those were FIT positive. Of these, 375 (56.13%) participants underwent a colonoscopy, and polyps were detected in 198 (52.8%) and cancers in 19 (5.1%) participants. The adenoma detection rate exceeded 40%. DISCUSSION AND CONCLUSION: The high yield of polyps and cancers in the screening program justifies an active, resource-intensive, and organized bowel cancer screening effort. The high adenoma detection rate in a FIT-based program warrants recalibration of target adenoma detection rates in screening programs.

RESUMO

Situs inversus totalis (SIT) is a rare congenital condition in which the abdominal and thoracic organs are completely reversed from right to left, and their diagnosis is usually incidental. However, patients with SIT need a comprehensive radiological evaluation before undertaking any invasive procedures. Percutaneous endoscopic gastrostomy (PEG) insertion is an effective procedure for enteral feeding in patients with difficulty swallowing. Many post-procedural complications have been reported after the PEG procedure. We performed PEG insertion in an 85-year-old Qatari SIT patient, who was admitted to the hospital as a case of aspiration pneumonia and on nasogastric feeding tube (NGT). The procedure was started while the patient was in left lateral decubitus position as in normal anatomy patients after careful examination and in accordance with the general principles of PEG insertion. No complications were seen, neither intraoperative nor postoperative in two months follow-up. We suggest that in a patient with SIT, PEG insertion can be performed while the patient is in left decubitus position with no additional risk or extra intraoperative time if the pre-operative anatomical position of vital organs is carefully evaluated.

RESUMO

PURPOSE: Demand for an organ transplant is surpassing the number of organ donors and hence increasing waiting lists worldwide, compelling many countries to adopt an opt-out consent system for organ donation. Opt-out is used in several European countries and has increased organ registration rate. No study on this subject has been published from the gulf region to associate sociodemographic characteristics, knowledge, attitude, beliefs, and intention domains regarding an opt-out consent for organ donation. MATERIALS AND METHODS: A household survey was conducted between October and November 2016 using a validated questionnaire. Integer codes were assigned for qualitative data to interpret results at par with quantitative data for each domain to allow data for advanced statistical analysis. RESULTS: Of 1044 surveyed participants, 724 (69.34%) those aged 37.7±10.4 agreed to adopting an opt-out consent system of which 231 (29.4%) were Qatari citizens and 353 (48.8%) were males. Mean levels of indices such as attitude, behavioral beliefs, and intention domains to organ donation were found higher in opt out participants. After adjusting statistical significant variables, multivariate analysis showed that attitude index was associated to opt out system (OR: 16.7, 95% C.I.:10.6-26.3, p=0.001) whereas; knowledge index (OR: 0.25, 95% C.I.: 0.07-0.83, p=0.03), behavioral beliefs (OR: 0.55, 95% C.I.: 0.35-0.86, p=0.009) and intention indices (OR: 0.42, 95% C.I.: 0.20-0.87, p=0.02) were associated with opt-in system for organ donation in Qatar. Regression model was able to discriminate (AUC: 84%, 95% C.I.:81% to 87%) for opt-out consent. Future probabilities for opt-out consent were 0.80, 0.88, 0.92,0.95,0.96,0.97,0.99 and 0.993 for 0.20, 0.30, 0.40, 0.50, 0.60, 0.70, 0.80 and 0.90 attitude levels after using 200 re-samples to make traditional multivariate regression model to realistic model for the population. CONCLUSION: The majority of the survey participants showed a good attitude but less knowledge, behavioral beliefs, and intention towards adopting an opt-out system for organ donation in Qatar.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus most commonly presents with respiratory symptoms. While gastrointestinal (GI) manifestations either at presentation or during hospitalization are also common, their impact on clinical outcomes is controversial. Some studies have described worse outcomes in COVID-19 patients with GI symptoms, while others have shown either no association or a protective effect. There is a need for consistent standards to describe GI symptoms in COVID-19 patients and to assess their effect on clinical outcomes, including mortality and disease severity. AIM: To investigate the prevalence of GI symptoms in hospitalized COVID-19 patients and their correlation with disease severity and clinical outcomes. METHODS: We retrospectively reviewed 601 consecutive adult COVID-19 patients requiring hospitalization between May 1-15, 2020. GI symptoms were recorded at admission and during hospitalization. Demographic, clinical, laboratory, and treatment data were retrieved. Clinical outcomes included all-cause mortality, disease severity at presentation, need for intensive care unit (ICU) admission, development of acute respiratory distress syndrome, and need for mechanical ventilation. Multivariate logistic regression model was used to identify independent predictors of the adverse outcomes. RESULTS: The prevalence of any GI symptom at admission was 27.1% and during hospitalization was 19.8%. The most common symptoms were nausea (98 patients), diarrhea (76 patients), vomiting (73 patients), and epigastric pain or discomfort (69 patients). There was no difference in the mortality between the two groups (6.21% vs 5.5%, P = 0.7). Patients with GI symptoms were more likely to have severe disease at presentation (33.13% vs 22.5%, P < 0.001) and prolonged hospital stay (15 d vs 14 d, P = 0.04). There was no difference in other clinical outcomes, including ICU admission, development of acute respiratory distress syndrome, or need for mechanical ventilation. Drugs associated with the development of GI symptoms during hospitalization were ribavirin (diarrhea 26.37% P < 0.001, anorexia 17.58%, P = 0.02), hydroxychloroquine (vomiting 28.52%, P = 0.009) and lopinavir/ritonavir (nausea 32.65% P = 0.049, vomiting 31.47% P = 0.004, and epigastric pain 12.65% P = 0.048). In the multivariate regression analysis, age > 65 years was associated with increased mortality risk [odds ratio (OR) 7.53, confidence interval (CI): 3.09-18.29, P < 0.001], ICU admission (OR: 1.79, CI: 1.13-2.83, P = 0.012), and need for mechanical ventilation (OR: 1.89, CI:1.94-2.99, P = 0.007). Hypertension was an independent risk factor for ICU admission (OR: 1.82, CI:1.17-2.84, P = 0.008) and need for mechanical ventilation (OR: 1.66, CI: 1.05-2.62, P = 0.028). CONCLUSION: Patients with GI symptoms are more likely to have severe disease at presentation; however, mortality and disease progression is not different between the two groups.

RESUMO

BACKGROUND: Pre-eclampsia is an inflammatory disorder characterized by diffuse endothelial dysfunction possibly secondary to impaired trophoblast invasion of the spiral arteries during implantation. It is associated with alterations in maternal serum concentrations of vascular endothelial growth factor (VEGF), placental growth factor (PIGF) and soluble fms-like tyrosine kinase-1 (sFlt-1). We did a case-control study to ascertain whether pre-eclampsia is associated with changes in serum concentrations of VEGF, PIGF and sFlt-1 in Indian patients. METHODS: Serum samples were obtained from 40 women with pre-eclampsia and 40 normotensive, non-proteinuric pregnant women. The levels of VEGF, PIGF and sFlt-1 were analysed using ELISA. RESULTS: In the sera of pregnant women with pre-eclampsia, the levels of sFlt-1 were significantly higher than those in the sera of normotensive, non-proteinuric pregnantwomen (median 11295.25 v. 2936.2 pg/ml, p < 0.0001), whereas there was a significant reduction in the levels of free VEGF (mean [SD] 170.53 [36.56] pg/ml v. 254.61 [47.39] pg/ml, p < 0.0001) and PIGF (mean [SD] 236.77 [93.70] pg/ml v. 744.98 [168.55] pg/ml, p < 0.0001). CONCLUSION: An increase in sFlt-1 levels and a simultaneous decrease in free VEGF and PIGF levels in the sera of women with pre-eclampsia as compared with normotensive, nonproteinuric pregnant women suggest that an imbalance between the levels of these pro- and anti-angiogenic factors'may have a role to play in the pathogenesis of pre-eclampsia.

RESUMO

BACKGROUND: Organ transplantation is considered as the last therapeutic option for the treatment for end-stage organ failure. However, the gap between the demand and supply of transplantable organs is still wide. Extensive researches have been conducted to understand this gap, and many countries have introduced Opt-out laws and have started targeted awareness programs. We aimed to assess, among the household residents, the normative behavior and beliefs and its correlation to intentions toward becoming organ donors. SUBJECTS AND METHODS: A household survey with the resident population of Qatar was conducted from October 2016 to November 2016. A sample of 1044 individuals aged 18 and above, residing in eight municipalities within the country, was selected using a two-stage systematic random sampling method to understand the relationship between organ donation intentions and behavioral, normative, and control beliefs. Independent female enumerators collected data on electronic tablets and exported to SPSS for data analysis. RESULTS: Data from 930/1044 (89%) individuals responded to the intention-related questions were taken for final analysis. Multivariate analysis brought out that behavioral beliefs (standardized beta coefficient = 0.25, t = 6.5, P = 0.001) and normative beliefs (standardized beta coefficient = 0.32, t = 8.4, P = 0.001) were significant contributors to intention to donate organs whereas control beliefs (standardized beta coefficient = -0.07, t = -2.3, P = 0.02) were negatively associated to organ donation intention. CONCLUSIONS: Findings indicate that behavioral and normative beliefs play a very important role in contributing to the intention of the individual toward organ donation.

RESUMO

Although numerous reports have compared the antimicrobial susceptibility of Campylobacter spp., controversy still exists about the use of the E test as an alternative to the agar dilution method suggested by the Clinical and Laboratory Standards Institute. MICs of 8 antimicrobials were determined using the E test and agar dilution methods for 103 Campylobacter jejuni and Campylobacter coli isolates from fresh chicken randomly purchased from stores in 3 southern Ontario counties. Overall, 72.6% of E test MIC values were within 1 log(2) dilution and 95.7% within 2 log(2) dilutions of the corresponding agar dilution MICs. For individual antimicrobials, agreement within 1 log(2) dilution and 2 log(2) dilutions was as follows: ampicillin (n = 103), 90.3% and 98.1%, respectively; chloramphenicol (n = 104), 85.6% and 99%; ciprofloxacin (n = 99), 51.5% and 97.0%; clindamycin (n = 99), 26.3% and 78.8%; erythromycin (n = 99), 52.5% and 96.0%; gentamicin (n = 99), 100% and 100%; nalidixic acid (n = 98), 91.8% and 99.0%; and tetracycline (n = 86), 82.6% and 97.7%. Relative to agar dilution, the E test underestimated the MIC value by a mean of 0.74 (ampicillin), 0.82 (chloramphenicol), 1.44 (ciprofloxacin), 1.94 (clindamycin), 1.40 (erythromycin), 0.21 (gentamicin), 0.94 (nalidixic acid), and 0.20 (tetracycline) log(2) dilutions and by a median of 1 log(2) dilution for all antimicrobials except clindamycin (2), gentamicin (0), and tetracycline (0). Cost analysis, including materials and labor, showed a 39.0% higher cost per analyte for the agar dilution method as compared with the E test. The most relevant advantage of the E test over the agar dilution method is the turnaround time because testing 99 strains by the agar dilution method takes 3.6 times longer compared with the E test using the same number of strains. The E test is an acceptable alternative for antimicrobial susceptibility testing in Campylobacter because it corresponds well with the agar dilution method although being considerably less expensive, is less labor intensive, and is more rapid. However, the relationship between E test and agar dilution MICs must be considered when interpreting E test results.
