Visual Perceptions Skills and its Association with Written Mathematical Communication Skills among Learning Disabilities Students in Jordan.

Aim: The present research sought at investigating the association between visual perception skills and written mathematical communication skills among a sample of students with learning disabilities in mathematics in Jordan. Method: This was a cross-sectional correlational study that included a sample of 90 primary-stage students who were diagnosed as having learning disabilities in mathematics. To collect data, the researchers developed two data collection tools; the visual perception skills test (50 items) and the written mathematical communication skills test (6 items). The tests were validated and ensured for reliability before implementation on the original study sample. The data gathered in this study was analyzed using the Statistical Package of Social Sciences (SPSS). Results: The results showed that there was a significant statistical association between visual discrimination and Written mathematical communication skills test (r=0.218), visual closing test and Written mathematical communication skills test (r=0.411), shape relationship perception test and Written mathematical communication skills test (r=0.438), Visual Integration and Spatial Relationship Perception Test and Written mathematical communication skills test (r=0.614), Visual information recall test and Written mathematical communication skills test (r=0.154). The results showed that there was a significant positive association between visual perception skills and written mathematical communication skills (r=0.509). Conclusion: The study ended up with that there is a significant positive association between visual perception skills and written mathematical communication skills among students with learning disabilities in mathematics. The study recommends developing mathematical educational material based on the visual approach and improving these skills among students with learning disabilities to develop their written mathematical communication skills.

Outcomes after cardiac arrest in Medical Intensive Care Unit: A propensity score matching analysis of COVID-19 MICU vs non COVID-19 MICU cardiac arrest.

AIM: To assess whether there were differences in resuscitation efforts and outcomes for medical intensive care unit (MICU) in-hospital cardiac arrest (IHCA) during the COVID-19 pandemic when compared to pre-pandemic. METHODS: Comparing COVID-19 MICU-IHCA patients (03/2020 to 10/2020) to non-COVID-19 MICU IHCA (01/2014 to 12/2018) at Clevleand Clinic Health System (CCHS) of NE Ohio. Propensity score matching analysis (PSMA) was used to create comparable groups. RESULTS: There were a total of 516 patients, 51 in COVID-19 MICU IHCA cohort and 465 in the non-COVID-19 MICU IHCA cohort. The mean (SD) age of the study population was 60.9 (16) years and 56% were males. In 92.1% (n = 475) patients, initial arrest rhythm was non-shockable. At the time of ICU admission, compared to the non-COVID-19 MICU-IHCA cohort, the COVID-19 MICU IHCA cohort had a lower mean APACHE III score (70 [32.9] vs 101.3 [39.6], P = <0.01). The COVID-19 cohort had a higher rate of survival to hospital discharge (12 [23.5%] vs 59 [12.7%], P = 0.03). Upon PSMA, the algorithm selected 40 COVID-19 patients and 200 non-COVID-19 patients. Imbalances in baseline characteristics, comorbidities, and APACHE III were well-balanced after matching. Survival rate after matching became non-significant; (10 [25%] vs 42 [21%], P = 0.67). Further, there were no significant differences in ICU or hospital length-of-stay or neurological outcomes at discharge for survivors in the two matched cohorts. CONCLUSION: It is imperative that COVID-19 patients receive unbiased and unrestricted resuscitation measures, without any discouragement.

Gastroduodeno-plasty performed by distal gastric transection.- A new technique for large duodenal defect closure.

INTRODUCTION: Duodenal ulcer lesions can represent a surgical challenge, especially if the duodenal wall is chronically inflamed, the defect exceeds a diameter of 3 cm and the ulceration is located in the second part of the duodenum. PATIENT AND METHOD: We present the case of a 70-year-old male, who suffered from a 3 x 4 cm duodenal defect caused by duodenal pressure necrosis due to a 12.5 x 5.5 x 5 cm gallstone. Additionally, this stone caused intestinal obstruction (Bouveret's syndrome) and bleeding with signs of shock. Besides the gallstone extraction, the common bile duct was drained by a T-tube and the duodenal defect closure was performed by a gastroduodeno-plasty and Bilroth II gastroenterostomy. The postoperative phase was uneventful. The reconstructed duodenum was endoscopically accessible and showed no pathological findings on follow-up. CONCLUSION: The reconstruction of a large defect (> 3 cm) of the second part of the duodenum is safely feasible by a gastroduodeno-plasty. The critical gastroduodenal anastomosis can be protected by duodenal decompression, achieved by placing a T-tube in the common bile duct.
