We present 8 years of experience based on the Qatar stroke database.SettingThe Qatar stroke database prospectively collects data on all stroke patients admitted to Hamad General Hospital. For this study, we compared female and male acute ischemic stroke patients on their characteristics at admission, short-term outcomes [modified Rankin Scale (mRS) score], and long-term outcomes [incidence of major adverse cardiovascular events (MACEs)].ParticipantsA total of 7,300 patients [F: 1,406 (19.3%), M: 5,894 (80.7%); mean age 55.1 ± 13.3 (F: 61.6 ± 15.1, M: 53.5 ± 12.3; p < 0.001)] were admitted with acute ischemic stroke.ResultsSignificantly fewer women presented within 4.5 h of onset (F: 29% vs. M: 32.8%; p = 0.01). Although women were more likely to experience severe stroke (NIHSS >10; F: 19.9% vs. M: 14.5%; p < 0.001), fewer were treated with thrombolysis (...

Endometrial polyps located at the fundal and tubocornual regions mechanically affect fertility. The recent advances in TVU and hysteroscopy provide an accurate diagnosis and effective treatment of polyp in the female reproductive tract. Objective: The goal of this systematic review is to highlight updates to the epidemiology, clinical presentation and imaging modalities for gynaecological polyps providing guidance to the best clinical decisions. It also highlights prevalence of infertility in gynaecological polyps. Study Design:

There is little data on real-world adherence to these recommendations. We evaluated the appropriateness of DAPT use in TIA and stroke patients in a prospective Database.MethodsThe Qatar Stroke Database began enrollment of patients with TIAs and acute stroke in 2014 and currently has ∼ 16,000 patients. For this study we evaluated the rates of guideline-adherent use of antiplatelet treatment at the time of discharge in patients with TIAs and stroke. TIAs were considered high-risk with ABCD2 score of ⍰ 4 and minor stroke was defined as NIHSS ⍰ 3. Patient demographics, clinical features, risk factors, previous medications, imaging and laboratory investigations, final diagnosis, discharge medications, and discharge and 90-day modified Rankin Scale (mRS) were analyzed.ResultsAfter excluding patients with ICH, mimics and...

We report our experience from a large prospective stroke database from Qatar. Methods: The Qatar stroke database is a prospective study, which began enrolling patients in 2014. We collected data on the demographics, clinical presentation, investigations, treatments, hospital complications and outcome (measured as 90-days modified Rankin Score [mRS]) on all patients admitted with acute stroke to the Hamad General Hospital where ~95% of stroke patients in Qatar are admitted. Multivariate analysis of risk factors, stroke type and severity, and in-hospital complications were compared to determine 90-days and one-year outcome in men and women. Results: There were 7300 stroke patients (women:1406 [19.3%], men:5894 [80.7%] admitted between 2014-2021. Multivariate analysis revealed significantly higher rates of obesity (OR 2.51), increasing age (age>65 years [OR 3.79]) and...

The structure of this antigen is currently unsolved experimentally. Here we present a homology model of the extracellular portion of the THSD7A antigen. The structure was evaluated for folding patterns, epitope site prediction, and function was predicted. Results show that this protein contains 21 extracellular domains and with the exception of the first two domains, has a regular repeating pattern of TSP‐1‐like followed by F‐spondin‐like domains. Our results indicate the presence of a novel Trp‐ladder sequence of WxxxxW in the TSP‐1‐like domains. Of the 21 domains, 18 were shown to have epitope binding sites as predicted by epitopia. Several of the F‐spondin‐like domains have insertions in the canonical TSP fold, most notably the coiled coil region in domain 4, which may be utilized in protein‐protein binding interactions, suggesting that this protein functions as a heparan sulfate binding site.

The association between the SARS‐CoV‐2 invasion mechanism and the renin‐angiotensin‐aldosterone system (RAAS) receptors, created many debates about the possible consequences of using RAAS‐modulating drugs including angiotensin‐converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs) during the pandemic. Many clinical studies were conducted to assess the outcomes of coronavirus disease 2019 (COVID‐19) in patients who use ACEi/ARBs following the arguments claiming to discontinue these drugs as a precautionary measure. Although several studies mainly analyzed the outcomes of the disease, this review aimed to compare specific blood markers in both groups of COVID‐19 patients to gain better insight into the interaction of ACEi/ARBs with different body functions during the infection. Several databases were searched using a combination of keywords followed by screening and data extraction. Only 28 studies met our inclusion criteria, the majority of which showed no significant difference between the inflammation markers of COVID‐19 patients who used or did not use ACEi/ARBs. Interestingly, 6 studies reported lower inflammatory markers in COVID‐19 patients who used ACEi/ARBs, and 6 studies reported better outcomes among the same group. We therefore concluded that the use of ACEi/ARBs may not lead to worse prognosis of COVID‐19 and may even play a protective role against the hyperinflammatory response associated with COVID‐19.
