RESUMEN
Middle East Respiratory Syndrome (MERS-CoV) is a coronavirus-caused viral respiratory infection initially detected in Saudi Arabia in 2012. In UAE, high seroprevalence (97.1) of MERS-CoV in camels was reported in several Emirate of Abu Dhabi studies, including camels in zoos, public escorts, and slaughterhouses. The objectives of this research include simulation of MERS-CoV spread using a customized animal disease spread model (i.e., customized stochastic model for the UAE; analyzing the MERS-CoV spread and prevalence based on camels age groups and identifying the optimum control MERS-CoV strategy. This study found that controlling animal mobility is the best management technique for minimizing epidemic length and the number of affected farms. This study also found that disease dissemination differs amongst camels of three ages: camel kids under the age of one, young camels aged one to four, and adult camels aged four and up; because of their immunological state, kids, as well as adults, had greater infection rates. To save immunization costs, it is advised that certain age groups be targeted and that intense ad hoc unexpected vaccinations be avoided. According to the study, choosing the best technique must consider both efficacy and cost.
RESUMEN
This report presents the clinical details and management of a 58-year-old Caucasian male with pericardial effusion and cardiac tamponade following outpatient inferior vena cava (IVC) filter removal. The patient was unresponsive and experienced cardiac arrest minutes after the procedure, requiring cardiopulmonary resuscitation. After return of spontaneous circulation he displayed somnolence, confusion and chest discomfort. Investigations revealed a large pericardial effusion, and an echocardiography confirmed cardiac tamponade. Prompt intervention involved pericardiocentesis, resulting in haemodynamic stabilisation and reduction in effusion size. The patient responded favourably with treatment. Differential diagnoses were considered and treatment options were discussed, highlighting the importance of timely recognition and appropriate intervention in managing pericardial effusion and cardiac tamponade. This report adds to the limited literature on pericardial effusion and cardiac tamponade following a scheduled outpatient IVC filter removal, emphasising the unique clinical presentation and successful management of this rare phenomenon. LEARNING POINTS: Understanding the link between pericardial effusion and cardiac tamponade following IVC filter removal.Recognising and differentiating cardiac tamponade from other emergencies using clinical and diagnostic tools.Learning the immediate management of cardiac tamponade, emphasising the role of pericardiocentesis.
RESUMEN
Defining the etiology of syncope can be occasionally challenging. We present a case with no history of coronary artery disease (CAD) who presented exclusively with exertional syncope, and was found to have mildly reduced left ventricular systolic dysfunction on echocardiogram and severe multi-vessel CAD with chronic total occlusion (CTO) of the right coronary artery (RCA). Syncope as the initial presentation of advanced CAD in the absence of classic ischemic symptoms is rather an uncommon presentation in clinical practice.
RESUMEN
BACKGROUND: Ward rounds are a cornerstone in the educational experience of junior doctors and an essential part of teaching patient care. Here, we aimed to assess the doctors' perception of ward rounds as an educational opportunity and to identify the obstacles faced in conducting a proper ward round in Sudanese hospitals. METHOD: A cross-sectional study was conducted from the 15th to the 30th of January 2022 among house officers, medical officers, and registrars in about 50 teaching and referral hospitals in Sudan. House officers and medical officers were considered the learners, while specialist registrars were considered the teachers. Doctors' perceptions were assessed using an online questionnaire, with a 5-level Likert scale to answer questions. RESULTS: A total of 2,011 doctors participated in this study (882 house officers, 697 medical officers, and 432 registrars). The participants were aged 26.9 ± 3.2 years, and females constituted about 60% of the sample. An average of 3.1 ± 6.8 ward rounds were conducted per week in our hospitals, with 11.1 ± 20.3 h spent on ward rounds per week. Most doctors agreed that ward rounds are suitable for teaching patient management (91.3%) and diagnostic investigations (89.1%). Almost all the doctors agreed that being interested in teaching (95.1%) and communicating appropriately with the patients (94.7%) make a good teacher in ward rounds. Furthermore, nearly all the doctors agreed that being interested in learning (94.3%) and communicating appropriately with the teacher (94.5%) make a good student on ward rounds. About 92.8% of the doctors stated that the quality of ward rounds could be improved. The most frequently reported obstacles faced during ward rounds were the noise (70%) and lack of privacy (77%) in the ward environment. CONCLUSION: Ward rounds have a special value in teaching patient diagnosis and management. Being interested in teaching/learning and having good communication skills were the two major criteria that make a good teacher/learner. Unfortunately, ward rounds are faced with obstacles related to the ward environment. It is mandatory to ensure the quality of both ward rounds' teaching and environment to optimize the educational value and subsequently improve patient care practice.

Organizing pneumonia (OP) is a form of interstitial lung disease that develops in response to acute lung injury. SARS-CoV-2 causes a wide range of lung and extrapulmonary disease, but there are few data suggesting an association between COVID-19 and OP. We describe a patient with COVID-19 pneumonia who developed severe progressive OP with significant morbidity. LEARNING POINTS: COVID-19 pneumonia is one of the secondary causes of organizing pneumonia (OP).Early initiation of steroids in OP is associated with improvement in symptoms and prognosis.A prolonged course of steroids may be needed in COVID-induced OP.
RESUMEN
The efficacy of anteriolateral versus anterior-posterior electrode positions in the success of atrial fibrillation's (AF) electrical cardioversion is unclear. Our aim is to perform a meta-analysis to compare the success rate of both electrode positions. PUBMED, WOS, OVID, and SCOPUS were searched. Inclusion criteria were clinical trials that compared anterior-lateral with anterior-posterior electrodes in external cardioversion of AF. After the full-text screening, 11 trials were included in the analysis. The total number of patients included in the study is 1845. The pooled analysis showed a statistically significant association between anterior-lateral electrode and increased cardioversion rate of AF (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.02-1.92, p = .04). Subgroup analysis revealed a statistically significant association between the anterior-lateral electrode and increased cardioversion rate of AF in subgroups of less than five shocks, patients with 60 years old or more and patients with left atrial (LA) diameter >45 mm (OR = 1.72, 95% CI = 1.17-2.54, p = .006), (OR = 1.73, 95% CI = 1.18-2.54, p = .005), and (OR = 1.86, 95% CI = 1.04-3.34, p = .04), respectively. Anteriolateral electrode is more effective than anterior-posterior electrode in external cardioversion of AF, particularly in patients who have received less than 5 shocks, are 60 years old or older and have a LA diameter greater than 45 mm.

BACKGROUND: Current guidelines from American College of Cardiology (ACC) recommend ticagrelor over clopidogrel in patients with acute coronary syndrome. We have observed many patients being switched from ticagrelor to clopidogrel after percutaneous coronary intervention (PCI) in our hospital. Our goal is to evaluate the use rate of ticagrelor and categorize the reasons for non-use. METHODS: We performed a retrospective data analysis of all patients who underwent PCI at Unity Hospital of Rochester, New York, from January 2019 to January 2020. A total of 330 patients underwent PCI for ACS over the year. After exclusions, 277 patients were enrolled in the analysis. RESULTS: Of the 277 patients, 179 (65%) completed one year of ticagrelor therapy, and 98 (35%) stopped ticagrelor and transitioned to clopidogrel. The most common reason for switching from ticagrelor was dyspnea (42 patients), followed by cost concerns (41 patients). CONCLUSION: At our community hospital, completion of one-year use of ticagrelor post-PCI occurred in 65% of patients. The most common reasons for discontinuation are dyspnea and medication cost.
RESUMEN
BACKGROUND: Heart failure with preserved ejection fraction is a complex clinical syndrome marked by different phenotypes and related comorbidities. Transthyretin amyloidosis is an underestimated phenotype. We aim to evaluate the prevalence of transthyretin amyloidosis in heart failure with preserved ejection fraction. METHODS: This meta-analysis was conducted according to PRISMA guidelines. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar to locate studies whose primary objective was to analyze the prevalence of transthyretin amyloidosis in heart failure preserved ejection fraction. RESULTS: Of 271 studies initially identified, 5 studies comprising 670 patients were included in the final analysis. The prevalence of transthyretin amyloidosis was 11%. Patients with transthyretin amyloid cardiomyopathy were more likely to be males (RR 1.38; 95% CI 1.09 to 1.75; P<0.01; I2=37%), and more likely to have low voltage criteria on ECG (RR 2.98; 95% CI 1.03 to 8.58; P=0.04; I2=75%) compared with transthyretin negative group. They also have higher SMD of age (SMD 0.73; 95% CI 0.48 to 0.97; P<0.01; I2=0%), and NT-proBNP (SMD 0.48; 95% CI 0.02 to 0.93; P=0.04; I2=36%) compared with transthyretin negative group. On reported echocardiogram, they have higher SMD of mass index (SMD 0.77; 95% CI 0.27 to 1.27; P<0.01; I2=65%), posterior wall thickness (SMD 0.92; 95% CI 0.62 to 1.21; P<0.01; I2=0%), and septal wall thickness (SMD 1.49; 95% CI 0.65 to 2.32; P<0.01; I2=87%) compared with transthyretin negative group. CONCLUSION: Transthyretin amyloidosis affects 11% of HFpEF patients. Therefore, screening HFpEF patients at risk of cardiac amyloidosis is warranted.
RESUMEN
BACKGROUND: Left atrial (LA) appendage closure (LAAC) is effective in patients with atrial fibrillation who are not candidates for long-term anticoagulation. However, the impact of LAAC on LA function is unknown. The aim of this study is to evaluate the impact of LAAC on atrial function. METHODS: This meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar for studies showing the effect of LAAC on the LA function from inception to November 20, 2021. The standardized mean difference (SMD) was calculated from the means and standard deviations. RESULTS: Of 247 studies initially identified, 8 studies comprising 260 patients were included in the final analysis. There was a significant increase in LA emptying fraction following LAAC compared with preoperative function (SMD: 0.53; 95% confidence interval [CI]: 0.04-1.01; p = .03; I2 = 75%). In contrast, there were no significant differences in LA volume (SMD: -0.07; 95% CI: -0.82-0.69; p = .86; I2 = 92%) peak atrial longitudinal strain (SMD: 0.50; 95% CI: -0.08-1.08; p = .09; I2 = 89%), peak atrial contraction strain (SMD: 0.38; 95% CI: -0.22-0.99; p = .21; I2 = 81%), strain during atrial contraction (SMD: -0.24; 95% CI: -0.61-0.13; p = .20; I2 = 0%), strain during ventricular systole (SMD: 0.47; 95% CI: -0.32-1.27; p = .24; I2 = 89%), strain during ventricular diastole (SMD: 0.09; 95% CI: -0.32-0.51; p = .66; I2 = 65%). CONCLUSION: LAAC is associated with improvement in the left atrial emptying fraction, but did not significantly influence other parameters.

BACKGROUND: Data on the effect of metformin on serum vitamin B12 (VitB12) level in patients with type 2 diabetes mellitus (T2DM) in Qatar are limited; therefore, we aimed to assess the prevalence of VitB12 deficiency and its related factors among patients with tbl2DM treated with metformin at Hamad General Hospital in Doha, Qatar, from January 1, 2017, to December 31, 2017. METHODS: This cross-sectional analytical study involved patients with tbl2DM aged ≥ 18 years who used metformin for at least 3 months. The serum VitB12 was quantified on a chemiluminescent enzyme immunoassay analyzer using Cobas e 801 module, Roche, and VitB12 deficiency was defined as serum VitB12 level of ≤ 145 pmol/L. All data were obtained from the patients' electronic medical records. RESULTS: The study recruited 3124 eligible patients with tbl2DM. The overall prevalence of metformin-associated VitB12 deficiency was 30.7% [95% confidence of interval, 0.290-0.323]. A significant difference exists in the median VitB12 levels between the VitB12-normal and VitB12-deficient groups [129 vs. 286; p < 0.001]. Compared with the VitB12-normal group, the VitB12-deficient group had higher mean body mass index (BMI) (p < 0.001) and consumed higher doses of metformin (p = 0.001). They also more often used sulfonylurea (p = 0.004), dipeptidyl peptidase-4 inhibitor (p < 0.001), thiazolidinediones (p < 0.001), glucagon-like peptide 1 [GLP-1] receptor agonists (p < 0.001), alpha-glucosidase inhibitor (p < 0.001), and H2 blocker/proton pump inhibitors [PPI] (p < 0.001) than the VitB12-normal group. Moreover, the VitB12-normal group consumed more calcium supplements (p < 0.001) than the VitB12-deficient group. In the multivariate analysis, independent risk factors for metformin-associated VitB12 deficiency in patients with tbl2DM include high daily dose of metformin >2000 mg, male gender, high BMI, smoking, sulfonylurea, dipeptidyl peptidase-4 inhibitor, H2 blockers/PPI, low fasting blood glucose, and low hemoglobin. CONCLUSION: This study showed a high prevalence of VitB12 deficiency in patients with tbl2DM taking metformin and a significant negative correlation between the daily dose of metformin and serum VitB12 level. Therefore, regular screening for serum VitB12 is necessary in patients with tbl2DM on metformin treatment, especially those who have the abovementioned risk factors.

BACKGROUND: Hospital length of stay (LOS) is a key determinant of heart failure hospitalization costs and performance of medical care quality. Right ventricular (RV) dysfunction predicted poor outcome in patients with acute heart failure (AHF). AIM: To study the effect of right ventricular function on length of hospital stay as a predictor in patients with acute heart failure. METHODS: A prospective cohort study was conducted in Cardiology Care Units (CCUs) in Zagazig University Hospital and Shark El Madina Hospital from September 2019 to February 2020, we included in this study 99 patients admitted with AHF. Clinical data and baseline RV function assessed by tricuspid annular plane systolic excursion (TAPSE) and S' velocity were collected. Clinical comorbidities including worsening renal function (WRF) were monitored during hospitalization. The primary outcome was hospital LOS. RESULTS: There was statistically significant correlation between WRF, right ventricular systolic dysfunction identified by TAPSE<16 mm and S' <9.5 cm/s and poor outcome in patients with acute heart failure including prolonged LOS. CONCLUSION: Right ventricular (RV) systolic dysfunction as assessed by TAPSE and S' velocity and diastolic dysfunction were independent predictors of longer LOS in AHF patients. WRF had high prevalence among patients with AHF and associated with poor outcome in AHF patients and prolonged LOS.
RESUMEN
BACKGROUND: Ischemic stroke is a devastating complication of atrial fibrillation (Afib). Anticoagulation is the gold standard to prevent stroke and systemic embolization. However, many patients have a contraindication to oral anticoagulation. The WATCHMAN device, which closes the left atrial appendage, is non-inferior to warfarin to prevent embolic events in clinical trials. Post-procedural anticoagulation is needed to avoid device-related thrombosis. The use of anticoagulants after WATCHMAN implantation in patients with high bleeding risks has been a source of debate. OBJECTIVE: This article summarizes the current evidence on anticoagulation following the implantation of the WATCHMAN device, focusing on patients who have an absolute contraindication to oral anticoagulation. OBSERVATION: The WATCHMAN device is efficacious and safe in preventing stroke and systemic embolization. Warfarin and aspirin are given for 45 days after implantation. If TEE at 45 days shows minimal residual peri-device flow (≤ 5mm) and no device-related thrombus, warfarin is stopped. This is followed by aspirin and clopidogrel for six months, then aspirin indefinitely. Antithrombotic therapy with aspirin and clopidogrel for six months followed by daily aspirin indefinitely may be feasible for patients with an absolute contraindication to OAC. DOACs are more convenient to use than warfarin, and limited evidence suggests that they are not inferior following implantation of the device. CONCLUSION: Following the WATCHMAN implantation, the most often utilized regimen is warfarin followed by antiplatelet treatment. In cases where there is a high risk of bleeding, antiplatelets alone may be sufficient. More research is needed to tailor the existing antithrombotic regimen to the needs of patients.

BACKGROUND Fever of unknown origin (FUO) is a diagnosis that requires a demanding workup from physicians before confirming a diagnosis. Thyroid diseases are a rare cause of FUO. Subacute thyroiditis is an inflammatory disease that can lead to a wide spectrum of presentations. CASE REPORT We report a case of a previously healthy male who presented with persistent fever of 4 weeks following an upper respiratory tract infection associated with constitutional symptoms. His laboratory workup included complete blood counts (CBC), complete metabolic panel (blood urea and creatinine, liver function tests, and serum electrolytes), blood cultures, abdominal and pelvic ultrasound, and computed tomography abdomen and pelvis that were inconclusive. His thyroid function tests showed a hyperthyroid state and a thyroid scan confirmed a picture of thyroiditis. The patient was treated with Ibuprofen and then with prednisolone; he showed significant improvement over a few days and was discharged with treatment of tapering doses of prednisolone over 6 weeks. Two weeks after discharge the patient had a follow-up at an outpatient clinic and was found to be in good health with resolution of his symptoms. CONCLUSIONS Thyroid disorders are not a common cause of FUO, and even if the clinical assessment of the patient is not suggestive of thyroid disease, we should consider it a possible cause. and thyroid function test should be performed to exclude thyroid problems.

Thrombotic disease represents a rare manifestation of leprosy. In this study, we report the case of an external jugular vein thrombosis associated with tuberculoid leprosy in a 23-year-old male patient. The patient presented with a 3-month history of painful cord-like swelling on the left side of the neck and a nearly 3-week history of skin lesions on the left cheek and right leg. Physical examination revealed cord-like, tender swelling on the left lateral aspect of the neck overlying the sternocleidomastoid muscle, and a hypopigmented, hypoaesthetic 6×7 cm lesion with an irregular margin on the left cheek. A Doppler ultrasound examination of the jugular vein showed thrombosis of the left external jugular vein. Three-dimensional reconstruction of the computed tomography scan showed the enlarged and enhanced left external jugular vein, as well as 1 of its tributaries, and the thickened skin patch. A skin punch biopsy from the left cheek lesion revealed granulomatous inflammation with occasional peri-adnexal granulomas, consistent with the clinical impression of tuberculoid leprosy. A diagnosis of leprosy with external jugular vein thrombosis was established. Anticoagulation therapy was initiated, and the patient was referred to an infectious disease clinic for treatment with anti-leprosy medications. LEARNING POINTS: Thickened cord-like neck swelling in leprosy can be vein thrombosis rather than a thickened nerve.Leprosy should be considered if a skin lesion is associated with thrombosis.The common causes of upper extremity DVT.
RESUMEN
BACKGROUND: Recently, use of nanotechnology in biomedical applications such as drug delivery and diagnostic and therapeutic tools has increased greatly. This study evaluated gold nanoparticle (GNPs)-induced nephrotoxic effects in rats in vivo, and examined protective effects of alpha-lipoic acid (α-Lip) and Vitamin E (Vit E) against nephrotoxicity, lipid peroxidation, and inflammatory kidney damage induced by GNPs. MATERIALS AND METHODS: Twenty-four male Wistar-Kyoto rats (220-240 g, 12 weeks old) were dosed with 50 µL of 10 nm GNPs administered intraperitoneally with or without 200 mg/kg/day Vit E or 200 mg/kg/day α-Lip. Serum was prepared for biochemical analyses. Kidney function was evaluated through measurement of creatinine (CR), uric acid (URIC), and blood urea nitrogen (BUN). Oxidative stress and lipid peroxidation were evaluated by measurement of reduced glutathione (GSH) and malondialdehyde (MDA) in kidney tissue homogenates. RESULTS AND CONCLUSIONS: The results showed a significant rise in serum kidney function biomarkers including urea, URIC, CR, and BUN in GNP-treated rats compared to normal control rats. Furthermore, GNPs led to decreased GSH and elevated MDA levels. Vit E or α-Lip supplementation showed a beneficial effect against nephrotoxicity, lipid peroxidation, and inflammatory kidney damage induced by GNPs. This study suggests that use of natural antioxidants in combination with GNPs may be a useful tool in preventing GNPs toxicity.

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder that causes isolated thrombocytopenia. Many viruses have been identified as triggering the autoimmune process, including HIV, MCV, EBV, parvovirus, rubella and measles. However, ITP in association with coronavirus infection has not previously been reported. We describe the case of a healthy man who presented with severe ITP complicated by intracranial haemorrhage following upper respiratory tract infection. An infection screen revealed coronavirus infection. LEARNING POINTS: Coronavirus can cause severe immune thrombocytopenic purpura (ITP).Intracerebral haemorrhage is an uncommon presentation of ITP.Intravenous immunoglobulin and steroids are very effective treatments for severe ITP.
RESUMEN
Ventricular arrhythmia storm is a state of cardiac instability characterized by multiple ventricular arrhythmias or multiple ICD therapies within a 24-hour duration. Management of this life-threatening state depends on the reversal of the cause besides either electrical or medical management of the arrhythmia. We report a case of a 54-year-old male who underwent a percutaneous coronary intervention following massive acute myocardial infarction. Afterwards, he developed frequent life-threatening ventricular arrhythmias that required multiple shocks and antiarrhythmic medications. Despite all these interventions, it was very difficult to control the electrical instability, but after overdrive ventricular pacing, the storm subsided and within a few days the case was stabilized. Overdrive pacing is an easy temporary modality to control the resistant arrhythmia following myocardial infarction.
RESUMEN
Uncontrolled hyperthyroidism has been associated with significant changes in cardiovascular hemodynamics. We report a case of a 39-year-old male who has been recently diagnosed with severe hyperthyroidism. He was undergoing dobutamine stress echocardiography (DSE) for evaluation of symptoms suggestive of stable angina. The exam was complicated by ST-segment elevation myocardial infarction- (STEMI-) required coronary angiography that showed mild coronary artery disease.
