Abstract Background The optimal amount and timing of protein intake in critically ill patients are unknown. REPLENISH (Replacing Protein via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial evaluates whether supplemental enteral protein added to standard enteral nutrition to achieve a high amount of enteral protein given from ICU day five until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve a moderate amount of enteral protein would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients. Methods In this multicenter randomized trial, critically ill patients will be randomized to receive supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition to achieve a high amount of enteral protein (range of 2–2.4 g/kg/day) or no supplemental enteral protein to achieve a moderate amount of enteral protein (0.8–1.2 g/kg/day). The primary outcome is 90-day all-cause mortality; other outcomes include functional and health-related quality-of-life assessments at 90 days. The study sample size of 2502 patients will have 80% power to detect a 5% absolute risk reduction in 90-day mortality from 30 to 25%. Consistent with international guidelines, this statistical analysis plan specifies the methods for evaluating primary and secondary outcomes and subgroups. Applying this statistical analysis plan to the REPLENISH trial will facilitate unbiased analyses of clinical data. Conclusion Ethics approval was obtained from the institutional review board, Ministry of National Guard Health Affairs, Riyadh, Saudi Arabia (RC19/414/R). Approvals were also obtained from the institutional review boards of each participating institution. Our findings will be disseminated in an international peer-reviewed journal and presented at relevant conferences and meetings. Trial registration ClinicalTrials.gov, NCT04475666 .

Abstract Background Inflammatory bowel disease (IBD) is a chronic gastrointestinal disease that causes anorexia, malabsorption, and increased energy requirements. Childhood IBD can significantly impact nutritional status and future health. Objective This study aimed to analyze the nutritional status of patients with pediatric IBD at presentation and during follow-up and to identify predictors of nutritional outcome. Methods This retrospective cohort study reviewed the medical records of children diagnosed with IBD in the Pediatric Department, Salmaniya Medical Complex, Bahrain, 1984 − 2023. Demographic data, clinical characteristics, and anthropometric data were collected. World Health Organization growth standards were used to interpret nutritional status. Results Of the 165 patients, 99 (60%) had anthropometric data at presentation, and 130 (78.8%) had follow-up data. Most patients were males (64.6%) and had Crohn’s disease (CD) (56.2%), while 43.8% had ulcerative colitis (UC). The median age at presentation was 10.9 years and the mean follow-up duration was 12.6 years. At presentation, 53.5% of the patients were malnourished, that decreased to 46.9% on follow-up. Thinness was reduced from 27.3% at presentation to 12.1% at follow-up (p = 0.003). There was an increased tendency to normal weight on follow-up (59.6%) compared to time of presentation (46.5%), p = 0.035. Overweightness showed a non-significant increase from 26.3% at presentation to 28.3% at follow-up (p = 0.791). Children with IBD were more likely to become obese when they grow up to adulthood (2.3% versus 20.5%, respectively, p

Hawani Sasmaya Prameswari, Triwedya Indra Dewi, Melawati Hasan, Erwan Martanto ,† Astri Astuti, Aninka Saboe, Charlotte Johanna Cool Department of Cardiology and Vascular Medicine, Faculty of Medicine, Padjadjaran University, Bandung, West Java, Indonesia†Erwan Martanto passed away on 17 August 2023Correspondence: Hawani Sasmaya Prameswari, Department of Cardiology and Vascular Medicine, Faculty of Medicine, Universitas Padjadjaran, Bandung, Indonesia, Email hawanisasmaya@gmail.comBackground: Due to the rarity of peripartum cardiomyopathy (PPCM) globally, baseline characteristic data for PPCM patients are still scarce. Therefore, this study aims to determine the baseline characteristics and 6-month outcomes of PPCM patients in Indonesia.Methods: From January 2014 to December 2021, all PPCM patients aged ≥ 18 years who were admitted to Dr. Hasan Sadikin General Hospital in Bandung, Indonesia, participated in this single-center, prospective cohort study. All patients were re-evaluated within 6 months of PPCM diagnosis.Results: A total of 138 patients with PPCM were admitted to Dr. Hasan Sadikin General Hospital in Bandung. The mean age of all patients was 30.4 ± 6.4 years old. Approximately 60% patients were multipara and had preeclampsia. All guideline-directed medical therapy for heart failure was received by most patients, excluding mineralocorticoid receptor antagonists (25.2%) and bromocriptine (14.1%). The neonatal mortality rate was 5.1%. Among those who survived, 61.2% had normal weight, 31.8% had low birth weight, and 7% had very low birth weight. At the 6-month follow-up, 6.7% of the patients died, 63.3% recovered, and 1.9% were rehospitalized.Conclusion: The present study found a high incidence of PPCM in Indonesia. Our patients frequently had preeclampsia, which contributed to the higher rate of miscarriage and low birth weight. Our liberal use of beta-blockers and ACEi/ARB may have contributed to the higher 6-month recovery rate than that in other countries.Keywords: peripartum cardiomyopathy, preeclampsia, PPCM, recovery, registry

Purpose: To assess the utility of using dynamic ultrasound for postoperative evaluation after superior capsular reconstruction (SCR) by evaluating graft integrity and its correlation with clinical outcomes at a minimum 2-year follow-up. Methods: A retrospective chart review was conducted to identify patients who underwent SCR between July 2015 and July 2020 with a minimum 2-year clinical and ultrasound follow-up. Clinical outcome measures included Simple Shoulder (SS) and American Shoulder and Elbow Surgeon (ASES) scores. Integrity of the SCR graft was evaluated by dynamic ultrasound. Results: We evaluated 22 shoulders in 21 patients with a mean follow-up of 44.8 months (range, 24-71 months). The graft was found to be intact by ultrasound evaluation in 82% (18/22). Patients with intact grafts had higher mean SS (11.6 vs 7.8, P = .00079) and ASES (91.2 vs 64.1, P = .0296) scores at latest follow-up compared to those with failed grafts. Those with intact grafts also had significant improvement in SS (3.7 vs 11.6, P < .00001) and ASES (23.2 vs 91.2, P < .00001) scores at latest follow-up compared to their preoperative scores. In contrast, patients with graft failure had no significant improvement in SS (6.3 vs 9.0, P = .123) and ASES (40.4 vs 58.3, P = .05469) scores at latest follow-up compared to their preoperative scores. There was no difference between clinical outcomes at 6 to 12 months vs latest follow-up for both SS (P = .11, P = .5) and ASES (P = .27, P = .21) scores. Conclusions: SCR grafts were found by ultrasound to be intact in 82% of cases. Patients with intact grafts on ultrasound had significant improvement in functional outcome scores while those with graft failure did not. Functional outcome scores suggest that maximal recovery from this procedure occurs by 6 to 12 months. Level of Evidence: Level IV, therapeutic case series.

Introduction. The objective of this study was to describe Do-Not-Resuscitate (DNR) practices in a tertiary-care intensive care unit (ICU) in Saudi Arabia, and determine the predictors and outcomes of patients who had DNR orders. Methods. This retrospective cohort study was based on a prospectively collected database for a medical-surgicalIntensive CareDepartment in a tertiary-care center in Riyadh, Saudi Arabia (1999–2017). We compared patients who had DNR orders during the ICU stay with those with “full code.” The primary outcome was hospital mortality. The secondary outcomes included ICU mortality, tracheostomy, duration of mechanical ventilation, and length of stay in the ICU and hospital. Results. Among 24790 patients admitted to the ICU over the 19-year study period, 3217 (13%) had DNR orders during the ICU stay. Compared to patients with “full code,” patients with DNR orders were older (median 67 years [Q1, Q3: 55, 76] versus 57 years [Q1, Q3: 33, 71], p

Infantile-onset multisystem neurologic, endocrine, and pancreatic disease (IMNEPD) is a rare autosomal recessive multisystemic disease with a prevalence of < 1/1 000 000. The wide spectrum of symptoms and associated diseases makes the diagnosis of this disease particularly challenging. Here, we report a 12-year-old Bahraini male who presented with the core clinical features of IMNEPD including intellectual disability, global developmental delay, sensorineural hearing loss, endocrine dysfunction, and exocrine pancreatic insufficiency. The diagnosis was confirmed by genetic testing using whole exome sequencing. This is the first reported case of IMNEPD from Bahrain and was found to have a novel homozygous peptidyl-tRNA hydrolase 2 (PTRH2) gene mutation (NM_001015509.2: c.370del p.(Glu124Lysfs*4)). Moreover, we conducted an extensive literature review with an emphasis on the variable clinical spectrum and genotypes of previously reported patients in comparison to our case.

Medicine ,Science - Abstract
BackgroundEarly identification of a patient with infection who may develop sepsis is of utmost importance. Unfortunately, this remains elusive because no single clinical measure or test can reflect complex pathophysiological changes in patients with sepsis. However, multiple clinical and laboratory parameters indicate impending sepsis and organ dysfunction. Screening tools using these parameters can help identify the condition, such as SIRS, quick SOFA (qSOFA), National Early Warning Score (NEWS), or Modified Early Warning Score (MEWS). We aim to externally validate qSOFA, SIRS, and NEWS/NEWS2/MEWS for in-hospital mortality among adult patients with suspected infection who presenting to the emergency department.Methods and analysisPASSEM study is an international prospective external validation cohort study. For 9 months, each participating center will recruit consecutive adult patients who visited the emergency departments with suspected infection and are planned for hospitalization. We will collect patients' demographics, vital signs measured in the triage, initial white blood cell count, and variables required to calculate Charlson Comorbidities Index; and follow patients for 90 days since their inclusion in the study. The primary outcome will be 30-days in-hospital mortality. The secondary outcome will be intensive care unit (ICU) admission, prolonged stay in the ICU (i.e., ≥72 hours), and 30- as well as 90-days all-cause mortality. The study started in December 2021 and planned to enroll 2851 patients to reach 200 in-hospital death. The sample size is adaptive and will be adjusted based on prespecified consecutive interim analyses.DiscussionPASSEM study will be the first international multicenter prospective cohort study that designated to externally validate qSOFA score, SIRS criteria, and EWSs for in-hospital mortality among adult patients with suspected infection presenting to the ED in the Middle East region.Study registrationThe study is registered at ClinicalTrials.gov (NCT05172479).

Background: Spontaneous coronary artery dissection and takotsubo cardiomyopathy are increasingly recognized in the last two decades. Case reports have shown both entities can present concomitantly - however, little is known about their association. Methods: In this retrospective study we aimed to explore a potential association between SCAD and TCM using the Nationwide Inpatient Sample. The odds of having TCM among patients with SCAD compared with those who did not have SCAD were calculated as an odds ratio. Conversely, the odds of having SCAD among patients with TCM compared with those who did not have TCM were also calculated. The primary outcome was the odds of TCM among patients with a primary diagnosis of SCAD and vice versa. The secondary endpoint was the odds of in-hospital mortality among patients with SCAD, and/or TCM. Results: Hospitalized patients who had SCAD were 7.12 (95 % CI: 6.28–8.08) times more likely to also have TCM than those who did not have SCAD (p

AbstractTocilizumab (TCZ) is recommended in patients with COVID-19 who require oxygen therapy or ventilatory support. Despite the wide use of TCZ, little is known about its safety and effectiveness in patients with COVID-19 and renal impairment. Therefore, this study evaluated the safety and effectiveness of TCZ in critically ill patients with COVID-19 and renal impairment. A multicenter retrospective cohort study included all adult COVID-19 patients with renal impairment (eGFR˂60 mL/min) admitted to the ICUs between March 2020 and July 2021. Patients were categorized into two groups based on TCZ use (Control vs. TCZ). The primary endpoint was the development of acute kidney injury (AKI) during ICU stay. We screened 1599 patients for eligibility; 394 patients were eligible, and 225 patients were included after PS matching (1:2 ratio); there were 75 TCZ-treated subjects and 150 controls. The rate of AKI was higher in the TCZ group compared with the control group (72.2% versus 57.4%; p = 0.03; OR: 1.83; 95% CI: 1.01, 3.34; p = 0.04). Additionally, the ICU length of stay was significantly longer in patients who received TCZ (17.5 days versus 12.5 days; p = 0.006, Beta coefficient: 0.30 days, 95% CI: 0.09, 0.50; p = 0.005). On the other hand, the 30-day and in-hospital mortality were lower in patients who received TCZ compared to the control group (HR: 0.45, 95% CI: 0.27, 0.73; p = 0.01 and HR: 0.63, 95% CI: 0.41, 0.96; p = 0.03, respectively). The use of TCZ in this population was associated with a statistically significantly higher rate of AKI while improving the overall survival on the other hand. Further research is needed to assess the risks and benefits of TCZ treatment in critically ill COVID-19 patients with renal impairment.

AbstractA novel, sensitive, economical, and environmentally friendly method is described for the quantitative determination of diphenhydramine hydrochloride (DPH). The method is based on the preparation of silver nanoparticles (AgNPs) from the extract of Capparis spinosa L. (CPL) fruits to determine DPH as one of the antihistamine drugs. The colour intensity of the solution increases with increasing DPH concentrations due to the interaction of AgNPs with DPH. FTIR, X-ray, EDX, SEM, and UV-Vis techniques characterised the prepared nanoparticles. The current method presented a linear relationship over the concentration range of 2–45 µg/mL at a wavelength of 415 nm. The detection limit (LOD) and quantitation limit(LOQ) are studied, and the values are 0.36 and 1.19 µg/mL, respectively. The recovery percentage (accuracy function) is more than 99.5%, and the relative standard deviation (RSD%, as a precision function) was 0.73%. The molar absorptivity and Sandel’s sensitivity index are 5.14 × 103 L.mol−1.cm−1 and 0.057 µg.cm−2, respectively. The data were compared to those from other previous approaches using t-test and F-test with a 95% confidence level and found to be 2.107 and 3.18, respectively. According to the ICH guidelines (2005), the proposed method has been validated and provides promising results for determination of DPH in pure form and pharmaceutical preparations.

Abstract Background Protein intake is recommended in critically ill patients to mitigate the negative effects of critical illness-induced catabolism and muscle wasting. However, the optimal dose of enteral protein remains unknown. We hypothesize that supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition formula to achieve high amount of enteral protein (range 2–2.4 g/kg/day) given from ICU day 5 until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve moderate amount enteral protein (0.8–1.2 g/kg/day) would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients. Methods The REPLENISH (Replacing Protein Via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial is an open-label, multicenter randomized clinical trial. Patients will be randomized to the supplemental protein group or the control group. Patients in both groups will receive the primary enteral formula as per the treating team, which includes a maximum protein 1.2 g/kg/day. The supplemental protein group will receive, in addition, supplemental protein at 1.2 g/kg/day starting the fifth ICU day. The control group will receive the primary formula without supplemental protein. The primary outcome is 90-day all-cause mortality. Other outcomes include functional and quality of life assessments at 90 days. The trial will enroll 2502 patients. Discussion The study has been initiated in September 2021. Interim analysis is planned at one third and two thirds of the target sample size. The study is expected to be completed by the end of 2025.

A key encapsulation mechanism (KEM{\mathsf{KEM}}) that takes as input an arbitrary string, i.e., a tag, is known as tag-KEM{\mathsf{KEM}}, while a scheme that combines signature and encryption is called signcryption. In this article, we present a code-based signcryption tag-KEM{\mathsf{KEM}} scheme. We utilize a code-based signature and an IND-CCA2{\mathsf{IND}}\hspace{0.1em}\text{-}\hspace{0.1em}{\mathsf{CCA2}} (adaptive chosen ciphertext attack) secure version of McEliece’s encryption scheme. The proposed scheme uses an equivalent subcode as a public code for the receiver, making the NP-completeness of the subcode equivalence problem be one of our main security assumptions. We then base the signcryption tag-KEM{\mathsf{KEM}} to design a code-based hybrid signcryption scheme. A hybrid scheme deploys asymmetric- as well as symmetric-key encryption. We give security analyses of both our schemes in the standard model and prove that they are secure against IND-CCA2{\mathsf{IND}}\hspace{0.1em}\text{-}\hspace{0.1em}{\mathsf{CCA2}} (indistinguishability under adaptive chosen ciphertext attack) and SUF-CMA{\mathsf{SUF}}\hspace{0.1em}\text{-}\hspace{0.1em}{\mathsf{CMA}} (strong existential unforgeability under chosen message attack).

This study discusses the overall performance of the behavior the shear stud in the composite steel beam. The work has been modeled by using ANSYS APDL program. Under of the influence of lateral horizontal pressure. The analyzed structure is a composite of beam-slab. The beam section is (254 X 254 X 73 kg/m) with slab of (1600 mm length, 1200 mm width and 150 mm height) and 6 headed studs 19mm diameter with 100 mm high featuring a single row of pointed studs spaced at 150 mm intervals. First, the study was placed on 200 mm from the end of the slabs on both sides. Headed studs and the value of the limited load are the most relevant dimensions for the aims of this study. One parameter was changed which was the load value. The resulted composite steel was analyzed for each change in the parameters. The results were compared to those from the experimental which revealed a possible alternate analysis that included the selected changes. Besides, the Von-mises stresses and stress intensity have been studied. It was found through structural analysis that there were stresses in the area of the studs which they are resistance to horizontal slips caused by lateral pressure loading. Four composite steel were evaluated at each parameter and were checked with the other factors. For this aim a utilizing parametric analysis software using ANSYS. Language of Design (APDL) was constructed to examine the behavior of the structure.

Abstract Background A thorough understanding of root and canal anatomy is crucial for successful root canal treatment outcomes. This systematic review aims to explore the published micro-CT studies investigated the anatomy of root and canal system in permanent mandibular first molars. Method An electronic search was performed on Web of science, PubMed, and Scopus. Micro-CT journal studies investigated the root and canal anatomy of permanent double-rooted mandibular first molars were included. Data on study characteristics, objectives of interest, specifications of the studies, and micro-CT specifications were extracted. Risk of bias assessment (ROB) of the included studies was performed using Anatomical Quality Assessment (AQUA) tool. The extracted data were presented in tables and figures to present and synthesise the results. A meta-analysis was performed for the studies related to the prevalence of Vertucci's canal configurations, middle mesial canal (MMC) configurations, and Fan's isthmus types. Results Amongst 1358 identified studies, thirty met the inclusion criteria. In terms of the objectives, the selected studies showed high anatomical variability in mandibular first molars. Twenty-two (73%), 25 (83%), and 12 (40%) of the studies reported the population/ethnicity, micro-CT specifications, and ethical approval, respectively. 28 (93%) studies did not disclose the method of sample size estimation. In only 6 (20%) of the studies, the authors had calibrated the assessment approaches. Mostly, a potential ROB was reported in domain 1 (objective(s) and subject characteristics) and domain 3 (methodology characterization). Whilst, low risk was reported in domains 2 (study design), 4 (descriptive anatomy), and 5 (reporting of results). The overall ROB was reported to be ''moderate'' in the vast majority of the studies (27/30). Meta-analysis results showed high levels of heterogeneity among the studies related to MMCs (I 2 = 86%) and Fan's isthmus (I 2 = 87%). As for the root canal configuration, pooled prevalence showed that Vertucci type IV and type I were the most prevalent in mesial and distal root canals, respectively. Conclusion Based on moderate risk of bias level of evidence, micro-CT studies have shown wide range of qualitative and quantitative data presentations of the roots and canals in mandibular first molars. Protocol and registration. The protocol of this systematic review was prospectively registered in the Open Science Framework database ( https://osf.io ) on 2022–06-20 with the registration number 10.17605/OSF.IO/EZP7K.

Kesehatan No. 1, Yogyakarta, 55281, Indonesia, Email hilmimuhammadortho@gmail.comIntroduction: Popliteal pterygium syndrome (PPS) is a rare autosomal-dominant condition that causes fixed flexion deformity of the knee. The popliteal webbing and shortening of the surrounding soft tissue could limit the functionality of the affected limb unless it is surgically corrected. We reported a case of PPS in a pediatric patient encountered in our hospital.Case: A 10-month-old boy came with a congenital abnormally flexed left knee with bilateral undescended testis and syndactyly of the left foot. The left popliteal pterygium extending from the buttock to the calcaneus was observed, with an associated fixed flexion contracture of the knee and equine position of the ankle. Normal vascular anatomy was seen in the angiographic CT scan; therefore, multiple Z-plasty and fibrotic band excision were performed. The sciatic trunk was exposed on the popliteal level, and the fascicular segment was excised from the distal stump and sutured to the proximal stump under the microscope to extend the sciatic nerve for approximately 7 cm. No postoperative complications were reported. Multiple tendons and soft tissue reconstruction were performed when the patient was 2-year-old to correct the adductus and equine deformity of the left foot.Discussion: Surgical correction for popliteal pterygium demands staged techniques to deal with the shortened structure. In our case, multiple Z-plasty were performed, and the fibrotic band was excised until its base with meticulous consideration of the underlying neurovascular bundle. Fascicular shifting technique for sciatic nerve lengthening can be considered in unilateral popliteal pterygium with difficulty extending the knee due to shortened sciatic nerve. The unfavorable outcome of nerve conduction disturbance resulting from the procedure may be multifactorial. Still, the existing foot deformity, including a certain degree of pes equinovarus could be treated by multiple soft tissue reconstructions and adequate rehabilitation to achieve the desired outcome.Conclusion: Multiple soft tissue procedures resulted in acceptable functional outcomes. However, the nerve grafting procedure is still a challenging task. Further study is required to explore the technique in optimizing the nerve grafting procedure for popliteal pterygium.Keywords: popliteal pterygium syndrome, multiple z-plasty, fascicular shifting, flexion contracture, case report

Abstract Prior research looking at Arab experiences in media education, despite its importance, did not provide a comprehensive evaluation of the curricula and study plans in Arab media colleges and departments but rather treated media education in a narrow and partial way. Therefore, this study fills this research gap by analysing the curricula of 21 media colleges, departments and institutes in 10 Arab countries from a perspective related to pressing issues of the Arab world, namely, the issues of diversity, pluralism, rights and freedoms. Three levels of content analysis were adopted to evaluate media education in the Middle East and North Africa—specifically, the learning objectives for managing diversity and differences based on UNESCO’s Media and Information Literacy Curriculum for Educators and Learners. The results showed that 33.2% (79 out of 238) of the total number of learning objectives in the UNESCO curriculum were specific to the skills of managing diversity. The study classified them into five main areas: promoting human rights, equality, pluralism, the culture of dialogue, and the commitment to ethics. Emphasis on adherence to media ethics was the most evident in all of the Arab academic plans, followed by, to a lesser extent, the emphasis on promoting the culture of dialogue, peace, and understanding, and finally promoting human rights. The weaknesses were represented in the lack of clarity on the items related to pluralism, democratic practice, equality, and the empowerment of women. The paper concludes with a discussion of the importance of adopting deeper methods of analysis to evaluate the items on enhancing diversity management in all Arab education curricula, in addition to the importance of establishing a practical discussion among decision-makers and experts to integrate new media education into the curricula of media students in line with advanced international experiences and take into account the notion of cultural privacy.

Abstract Background This study assessed the mobility levels among critically ill patients and the association of early mobility with incident proximal lower-limb deep-vein thrombosis and 90-day mortality. Methods This was a post hoc analysis of the multicenter PREVENT trial, which evaluated adjunctive intermittent pneumatic compression in critically ill patients receiving pharmacologic thromboprophylaxis with an expected ICU stay ≥ 72 h and found no effect on the primary outcome of incident proximal lower-limb deep-vein thrombosis. Mobility levels were documented daily up to day 28 in the ICU using a tool with an 8-point ordinal scale. We categorized patients according to mobility levels within the first 3 ICU days into three groups: early mobility level 4–7 (at least active standing), 1–3 (passive transfer from bed to chair or active sitting), and 0 (passive range of motion). We evaluated the association of early mobility and incident lower-limb deep-vein thrombosis and 90-day mortality by Cox proportional models adjusting for randomization and other co-variables. Results Of 1708 patients, only 85 (5.0%) had early mobility level 4–7 and 356 (20.8%) level 1–3, while 1267 (74.2%) had early mobility level 0. Patients with early mobility levels 4–7 and 1–3 had less illness severity, femoral central venous catheters, and organ support compared to patients with mobility level 0. Incident proximal lower-limb deep-vein thrombosis occurred in 1/85 (1.3%) patients in the early mobility 4–7 group, 7/348 (2.0%) patients in mobility 1–3 group, and 50/1230 (4.1%) patients in mobility 0 group. Compared with early mobility group 0, mobility groups 4–7 and 1–3 were not associated with differences in incident proximal lower-limb deep-vein thrombosis (adjusted hazard ratio [aHR] 1.19, 95% confidence interval [CI] 0.16, 8.90; p = 0.87 and 0.91, 95% CI 0.39, 2.12; p = 0.83, respectively). However, early mobility groups 4–7 and 1–3 had lower 90-day mortality (aHR 0.47, 95% CI 0.22, 1.01; p = 0.052, and 0.43, 95% CI 0.30, 0.62; p

Vaccine trials were started in November 2020, and completed rapidly due to the urgency to get over the infection. Side effects to vaccines started to be reported. There were minor side effects including site of injection pain and heaviness and constitutional symptoms like fever which are considered minor. One of the rare adverse events is post vaccine new onset autoimmune diseases.Methods: Data were obtained from one center in the eastern province of Saudi Arabia (King Fahd Hospital of University). All patient events reported occurred in the study period March 2021 to February 2022. We identified patients presenting with autoimmune diseases with exclusively new onset presentations.Results: We identified 31 cases of immune-mediated disease: 18 females (58%); 13 males (42%). Only 4 of them (13%) had an autoimmune background before COVID-19 vaccination. The average time between vaccination and new-onset disease symptoms was 7 days. Among all the cases in our study, 7 patients (22.5%) had new-onset vasculitis, 2 cases had IgA vasculitis and 5 cases had ANCA vasculitis, 6 cases had neurological diseases (19.3%), 4 cases (12.9%) had new-onset systemic lupus erythematosus (SLE), 3 cases (9.6%) presented with new-onset inflammatory arthritis, and one had Sjogren’s syndrome (3.2%).Conclusion: Our study is unique as it is the first study to include the largest number (31 patients) of new onsets of confirmed autoimmune diseases related to Covid-19 vaccines.Keywords: autoimmune disease, SARS CoV-2, vaccine, immune-mediated disease

Background: The e-prescriptions service connects primary healthcare centers and hospitals to selected community pharmacies in various locations to allow easy access to the nearest pharmacy in the neighborhood, thus facilitating the process of drug dispensing. This study aims to assess patients' satisfaction towards Wasfaty services delivered by Ministry of Health healthcare centers. Materials and Methods: A cross-sectional study was conducted in Al Ahsa province in Saudi Arabia among adult patients who used Wasfaty services. An electronic Arabic questionnaire including demographic characteristics of patients and questions to assess their satisfaction level with the e-prescription “Wasfaty” service in terms of different aspects. Results: A total of 481 participants were included in the study. Females represented 53.4% of them, and 28.1% were aged 50 years or over. Overall, most of the patients (84.1%) were either satisfied or strongly satisfied with the service (4.28 ± 0.57). After controlling for confounding, patients with chronic diseases were more satisfied with the “wasfaty” service compared to those without chronic diseases. The history of chronic disease was responsible for approximately 2.4% variability of patient satisfaction (r-square = 0.024). Patients' geographic region, age, sex, and educational level were not significantly associated with their satisfaction with “wasfaty” service. Conclusion: The majority of patients, particularly those with chronic diseases, were satisfied with Wasfaty service. However, less satisfaction was observed regarding medication availability.

Sustainability is providing the needs without compromising the ability of the strategical forming to meet their requirements. The production of warm asphalt mixtures using recycled pavements produces economic and environmentally friendly mixtures, which is the most important advantage of this work. This research aims to determine the effect of recycled asphalt concrete (RAP) on the indirect tensile strength of warm asphalt mixtures and Marshall Properties. Models of warm asphalt mixtures using Aggregate from the Al-Nibaay quarry, Asphalt with a degree of penetration (40-50) from the refinery of the cycle, and obtained Recycled asphalt concrete from Salah Al-Din Road, Al-Ameriya area in Baghdad are prepared. Use five ratios of (0, 10, 20, 30, and 40%) of recycled asphalt concrete. Marshall Design method is adopted to estimate the perfect existence of the asphalt cement for sample preparation. The mixtures properties, volumetric properties, and indirect tensile strength test are evaluated to assess bonding strength. Results show that the increase in the replacement percentage of RAP causes an increase in flow and air void and decreases the bulk density, voids in mineral aggregate (VMA), and voids filled with Asphalt (VFA). Stability increases with increased RAP content until it reaches its peak and falls. The highest stability value is at 30% RAP by 58%, about the indirect tensile strength test. The increase in the RAP ratio increases the tensile strength and the bonding between the components. So including RAP material in warm asphalt mixtures improves properties and meets performance requirements.

A new pavement technology has been developed in Highway engineering: asphalt pavement production is less susceptible to oxidation and the consequent damages. The warm mix asphalt (WMA) is produced at a temperature of about (10-40) oC lower than the hot asphalt paving. This is done using one of the methods of producing a WMA. Although WMA's performance is rather good, according to previous studies, as it is less susceptible to oxidation, it is possible to modify some of its properties using different materials, including polymers. Waste tires of vehicles are one of the types of polymers because of their flexible properties. The production of HMA, WMA, and WMA modified with proportions of (1, 1.5, and 2%) of rubber crumbs by the dry method are accomplished in this work. Marshall Test and volumetric properties determination are performed to evaluate its performance. The results showed that using 1% of rubber crumbs as a replacement for fine aggregate in the warm asphalt mixture produced the best properties of the WMA compared to the conventional WMA.

The simulate microphysical processes in the atmosphere, a cloud chamber, which behaves as the atmosphere, has been designed and fabricated in order to be used to execute several atmospheric experiments. These experiments allow a better understanding of clear visual cloud formation. The executed temperature and saturated pressure experiments clarify the basic mechanisms of the ice crystals nucleation, which in contrast, represent the core of the cloud microphysics. The cloud chamber can represent an isolated environment that deals with a certain volume of pure air and contains certain nucleation particles or ice nuclei. The temperature range in such a chamber is similar to that found at the mid-latitudes between the surface of the earth and the top of the troposphere. Thus, it is possible to simulate clouds of the type of Cirrostratus at the bottom of the chamber. It has been designed with dimensions of 22×22×59 cm3 and made of 3mm in thickness copper with a purity of 99.9%, and thermal conductivity of 401 W/m.°K.

Abstract Background Globally, the increased use of cesarean sections has become prevalent in high-income and low and middle-income countries. In Palestine, the rate had risen from 20.3% in 2014 to 25.1% in 2018. We have rates as high as 35.8% in some governmental hospitals and some as low as 15%. This study aimed to understand better why there is a variation in cesarean rates in governmental hospitals that use the same guidelines. Methods A qualitative and quantitative research approach was used. In-depth interviews were conducted with 27 specialists, obstetrics and gynecologists, and midwives in five government hospitals. The hospitals were selected based on the 2017 Annual Health Report reported cesarean section rates. The interview guide was created with the support of specialists and researchers and was piloted. Questions focused mainly on adherence to the obstetric guidelines and barriers to the use, sources of information, training for healthcare providers, the hospital system, and the factors that affect decision-making. Each hospital's delivery records for one month were analyzed to determine the reason for each cesarean section. Results The results indicated that each governmental hospital at the system level had a different policy on cesarean sections. The National Guidelines were found to be interpreted differently among hospitals. One obstetrician-gynecologist decided on a cesarean section at high-rate hospitals, while low-rate hospitals used collective decision-making with empowered midwives. At the professional level, all hospitals urged the importance of a continuous training program to refresh the medical team knowledge, in-house training of new members joining the hospital, and discussion of cases subjective to obstetrician-gynecologists interpretations. Conclusion Several institutional factors were identified to strengthen the implementation of the national obstetric guidelines. For example, encouraging collective decision-making between obstetrician-gynecologists and midwives, promoting the use of a second opinion, and mandatory training.

Abstract Background Thrombotic events are common in critically ill patients with COVID-19 and have been linked with COVID-19- induced hyperinflammatory state. In addition to anticoagulant effects, heparin and its derivatives have various anti-inflammatory and immunomodulatory properties that may affect patient outcomes. This study compared the effectiveness and safety of prophylactic standard-doses of enoxaparin and unfractionated heparin (UFH) in critically ill patients with COVID-19. Methods A multicenter, retrospective cohort study included critically ill adult patients with COVID-19 admitted to the ICU between March 2020 and July 2021. Patients were categorized into two groups based on the type of pharmacological VTE thromboprophylaxis given in fixed doses (Enoxaparin 40 mg SQ every 24 hours versus UFH 5000 Units SQ every 8 hours) throughout their ICU stay. The primary endpoint was all cases of thrombosis. Other endpoints were considered secondary. Propensity score (PS) matching was used to match patients (1:1 ratio) between the two groups based on the predefined criteria. Multivariable logistic, Cox proportional hazards, and negative binomial regression analysis were used as appropriate. Results A total of 306 patients were eligible based on the eligibility criteria; 130 patients were included after PS matching (1:1 ratio). Patients who received UFH compared to enoxaparin had higher all thrombosis events at crude analysis (18.3% vs. 4.6%; p-value = 0.02 as well in logistic regression analysis (OR: 4.10 (1.05, 15.93); p-value = 0.04). Although there were no significant differences in all bleeding cases and major bleeding between the two groups (OR: 0.40 (0.07, 2.29); p-value = 0.31 and OR: 1.10 (0.14, 8.56); p-value = 0.93, respectively); however, blood transfusion requirement was higher in the UFH group but did not reach statistical significance (OR: 2.98 (0.85, 10.39); p-value = 0.09). The 30-day and in-hospital mortality were similar between the two groups at Cox hazards regression analysis. In contrast, hospital LOS was longer in the UFH group; however, it did not reach the statistically significant difference (beta coefficient: 0.22; 95% CI: -0.03, 0.48; p-value = 0.09). Conclusion Prophylactic enoxaparin use in critically ill patients with COVID-19 may significantly reduce all thrombosis cases with similar bleeding risk compared to UFH.

In this study, natural fibers were extracted from Imperata cylindrica (ICY) by mechanical fractionation followed by characterization. The morphological, microstructural, and thermal properties of ICY fibers were examined by scanning electron microscopy (SEM), energy-dispersive X-ray, and thermal gravimetric analysis (TGA). Kinetic analysis was examined through Flynn Wall Ozawa (FWO) and Kissinger Akahira Sunose (KAS) models. Results showed that mechanical fractionation successfully extracted natural fibers from ICY. SEM analyses revealed a compact surface structure interrupted by contours and protrusions due to disoriented fractionation of the fibers. Thermal analysis revealed significant mass loss (72.94–77.03%), whereas the TG/DTG plots shifted correspondingly due to multiple heating rates (10–30°C/min) and thermal lag during TGA from 30 to 800°C. Likewise, the onset, midpoint, offset, drying, and devolatilization peak temperatures increased at higher heating rates. Tons increased from 257.99–269.25°C, whereas Tmid was 313.57–319.17°C, Toff was 363.70–376.58°C. The OFW and KAS kinetic models revealed activation energy (Ea) and frequency factor (ko) ranged from 38.09 to 514.33 kJ mol−1 and 1.65 × 1002 to 1.24 × 1048 min−1, respectively, for conversions α = 0.05 to 0.95, which indicate ICY fibers are thermally stable and suitable for utilization as bio-composite reinforcement.

Materials and methods This is a retrospective comparative study. Cone-beam computed tomography images of one hundred and fifty adult patients were divided into three equal groups: unilateral, bilateral, and control groups. Each had 50 patients that were three-dimensionally analysed. The quantitative measurements involved three basal (molar basal width, premolar basal width, and arch depth), seven dentoalveolar (molar alveolar width, premolar alveolar width, inter-molar width, inter-premolar width, inter-canine width, arch length, and arch perimeter), and two dental (canine length and width) measurements. The qualitative measurements included four bone density areas (buccal, lingual, mesial, and distal) around the maxillary impacted canines. Result Differences between the three groups were statistically different for the quantitative measurements involving the two basal variables (molar basal width and premolar basal width) and all measured dentoalveolar variables; these were smaller in the unilateral and bilateral groups compared with the control group (p

For power plant networks in developing countries like Iraq, balancing electricity demand and generation continues to be a major challenge. Energy management (EM) in either demand-side (DS) or generation-side (GS) strategies, which is frequently utilized in Iraq due to a lack of adequate power generation, has a small impact on the power balancing mechanism. Most previous studies in similar countries discussed only the application of DS strategies. The purpose of this paper is to contrast and review various energy management methodologies being used in developing nations facing power outages, to be able to recommend suitable ones according to the country’s situation. To assess potential EM-based solutions to improve the total energy efficiency of the Iraqi electrical community, a thorough and methodical analysis was carried out. The main objective of this review paper is to discuss the causes of power outages and the energy management strategies addressed here as methods to mitigate or avoid power outages. Unlike existing reviews that concentrated on demand-side energy management, this study specifically focuses on power outage causes in developing countries like Iraq rather than all management strategies. It also introduces the consequences of power outages including analysis of distribution power losses, financial loss from power blackouts, and power blackouts in firms in a typical month. Therefore, it presents readers with state-of-the-art strategies and recommends a generation-based EM strategy to mitigate such issues.

Objectives: Though the prevalence of biliary atresia (BA) in the Middle East is low, its role in causing life-threatening liver diseases is disproportionately high. This study aimed to assess the prevalence, clinical presentations, diagnosis, surgical interventions, and long-term outcomes including survival rate, and to analyze prognostic factors affecting the survival of infants with BA in Bahrain. Methods: A retrospective cohort review of cases of infants diagnosed with BA between January 1993 and December 2021 at Salmaniya Medical Complex, Bahrain, was conducted. Demographic, clinical, laboratory, imaging, and histopathological data were analyzed. Outcomes measured included 5-year native liver survival (NLS) and overall liver survival (OLS) rates. Results: Out of 27 infants diagnosed with BA, 26 were included in the study. The overall prevalence was 0.007% and was significantly higher among Bahraini (0.006%) compared to the non-Bahraini population (0.001%), p< 0.001. Most patients had clay-colored stool (19 of 22; 86.4%) and hepatomegaly (18; 81.8%). Kasai procedure was performed in 23 (88.5%) patients and primary liver transplant (LT) in three. Ten (38.5%) infants required LT after the Kasai procedure. The median age at diagnosis was 56 days with interquartile range (IQR) of 30–90, and the median age at the Kasai procedure was 61 days (IQR = 56–90). NLS and OLS rates were 53.8% and 65.4%, respectively. The overall mortality rate was 34.6%. Six of the 13 (46.2%) patients who were subjected to Kasai procedure alone died awaiting LT donors. Infants with lower birth weight and older age at diagnosis had significantly better odds of survival (p< 0.029 and p< 0.044, respectively). Conclusions: BA is uncommon among infants in Bahrain. Despite effective treatment options, late diagnosis can lead to significant morbidity and mortality. Our study found a relatively low prevalence of NLS (53.8%) and OLS (65.4%). Since the majority of the diagnosed patients had presented with clay-colored stools, implementing an infant stool card for screening may be beneficial in raising parental awareness and detecting BA early. Early detection and treatment using novel therapies are likely to improve the survival rates.

Background: Antibiotic-resistant Acinetobacter baumannii is a continuously-emerging worldwide health crisis, with mortality rates approaching 50% in intensive care unit (ICU) patients. The objective of this study was to evaluate regional, patient-related, and organism-related predictors of survival among critically-ill patients with confirmed Acinetobacter infection. Methods: This prospective cohort study was conducted within ten ICUs across six geographically- and climatologically-distinct cities across Saudi Arabia over 13 months. Results: Of 169 patients with confirmed Acinetobacter infection enrolled in the study, 80 (47.6%) died. Survivors were statistically younger, predominantly male, more likely to be admitted for trauma, less likely to have hypertension, diabetes, or have undergone hemodialysis, and more likely to have been treated with antibiotics prior to having a positive culture for Acinetobacter, but less likely to have received an aminoglycoside. Survivors also had lower baseline APACHE II and SOFA scores and were infected with stains of Acinetobacter that had less meropenem- or colistin-resistance. Multivariate analysis identified the following independent predictors of survival: younger age, lower ICU-day#1 APACHE-II and ICU-day#3 SOFA scores, being admitted for trauma, and having no history of hemodialysis. Conclusions: Patient-related factors outweigh regional and hospital-related factors as predictors of survival among critically-ill patients with Acinetobacter infection.

Abstract There are contradictory data regarding the effect of intermittent pneumatic compression (IPC) on the incidence of deep-vein thrombosis (DVT) and heart failure (HF) decompensation in critically ill patients. This study evaluated the effect of adjunctive use of IPC on the rate of incident DVT and ventilation-free days among critically ill patients with HF. In this pre-specified secondary analysis of the PREVENT trial (N = 2003), we compared the effect of adjunctive IPC added to pharmacologic thromboprophylaxis (IPC group), with pharmacologic thromboprophylaxis alone (control group) in critically ill patients with HF. The presence of HF was determined by the treating teams according to local practices. Patients were stratified according to preserved (≥ 40%) versus reduced (

The current pandemic of the novel coronavirus disease 2019 (COVID-19) originated in Wuhan, China in December 2019. The most common clinical manifestations are fever, fatigue, and cough. Other common symptoms include anorexia, chest tightness and shortness of breath. Extrapulmonary manifestations including gastrointestinal symptoms were also reported in patients with COVID-19 infection. It has been found that the ACE2 receptor of SARS-CoV-2 is expressed more in the pancreas than in the lungs. However, only few cases reported with pancreatic injury were caused by COVID-19. In this paper, we report a young patient presenting with acute necrotizing pancreatitis that is complicated with portal vein thrombosis and found to have COVID-19 infection.

Background. Intravenous infusions of neuromuscular blocking agents (NMBAs) and prone positioning are recommended for acute respiratory distress syndrome (ARDS) due to COVID-19. The safety of enteral nutrition (EN) during these treatments is unclear. This study assessed EN tolerance and safety during NMBA infusion in proned and nonproned patients with ARDS due to COVID-19. Methods. This retrospective study evaluated patients who were admitted to a tertiary-care ICU between March and December 2020, had ARDS due to COVID-19, and received NMBA infusion. We assessed their EN data, gastrointestinal events, and clinical outcomes. The primary outcome was gastrointestinal intolerance, defined as a gastric residual volume (GRV) ≥500 ml or 200–500 ml with vomiting. We compared proned and nonproned patients. Results. We studied 181 patients (mean age 61.2 ± 13.7 years, males 71.1%, and median body mass index 31.4 kg/m2). Most (63.5%) patients were proned, and 94.3% received EN in the first 48 hours of NMBA infusion at a median dose

Diseases of the respiratory system ,RC705-779 - Abstract
Background. Respiratory syncytial virus (RSV), a well-known cause of bronchiolitis in children, can cause community-acquired pneumonia (CAP) in adults, but this condition is not well studied. Hence, we described the characteristics and outcomes of patients hospitalized for CAP due to RSV. Methods. This was a retrospective study of patients admitted to a tertiary-care hospital between 2016 and 2019 with CAP due to RSV diagnosed by a respiratory multiplex PCR within 48 hours of admission. We compared patients who required ICU admission to those who did not. Results. Eighty adult patients were hospitalized with CAP due to RSV (median age 69.0 years, hypertension 65.0%, diabetes 58.8%, chronic respiratory disease 52.5%, and immunosuppression 17.5%); 19 (23.8%) patients required ICU admission. The median pneumonia severity index score was 120.5 (140.0 for ICU and 102.0 for non-ICU patients; p=0.09). Bacterial coinfection was rare (10.0%). Patients who required ICU admission had more hypotension (systolic blood pressure

Objective. Pulmonary barotrauma has been frequently observed in patients with COVID-19 who present with acute hypoxemic respiratory failure. This study evaluated the prevalence, risk factors, and outcomes of barotrauma in patients with COVID-19 requiring ICU admission. Methods. This retrospective cohort study included patients with confirmed COVID-19 who were admitted to an adult ICU between March and December 2020. We compared patients who had barotrauma with those who did not. A multivariable logistic regression analysis was performed to determine the predictors of barotrauma and hospital mortality. Results. Of 481 patients in the study cohort, 49 (10.2%, 95% confidence interval: 7.6–13.2%) developed barotrauma on a median of 4 days after ICU admission. Barotrauma manifested as pneumothorax (N = 21), pneumomediastinum (N = 25), and subcutaneous emphysema (N = 25) with frequent overlap. Chronic comorbidities and inflammatory markers were similar in both patient groups. Barotrauma occurred in 4/132 patients (3.0%) who received noninvasive ventilation without intubation, and in 43/280 patients (15.4%) who received invasive mechanical ventilation. Invasive mechanical ventilation was the only risk factor for barotrauma (odds ratio: 14.558, 95% confidence interval: 1.833–115.601). Patients with barotrauma had higher hospital mortality (69.4% versus 37.0%; p

Medicine ,Science - Abstract
This prospective quasi-experimental study from the NASAM (National Approach to Standardize and Improve Mechanical Ventilation) collaborative assessed the impact of evidence-based practices including subglottic suctioning, daily assessment for spontaneous awakening trial (SAT), spontaneous breathing trial (SBT), head of bed elevation, and avoidance of neuromuscular blockers unless otherwise indicated. The study outcomes included VAE (primary) and intensive care unit (ICU) mortality. Changes in daily care process measures and outcomes were evaluated using repeated measures mixed modeling. The results were reported as incident rate ratio (IRR) for each additional month with 95% confidence interval (CI). A comprehensive program that included education on evidence-based practices for optimal care of mechanically ventilated patients with real-time benchmarking of daily care process measures to drive improvement in forty-two ICUs from 26 hospitals in Saudi Arabia (>27,000 days of observation). Compliance with subglottic suctioning, SAT and SBT increased monthly during the project by 3.5%, 2.1% and 1.9%, respectively (IRR 1.035, 95%CI 1.007-1.064, p = 0.0148; 1.021, 95% CI 1.010-1.032, p = 0.0003; and 1.019, 95%CI 1.009-1.029, p = 0.0001, respectively). The use of neuromuscular blockers decreased monthly by 2.5% (IRR 0.975, 95%CI 0.953-0.998, p = 0.0341). The compliance with head of bed elevation was high at baseline and did not change over time. Based on data for 83153 ventilator days, VAE rate was 15.2/1000 ventilator day (95%CI 12.6-18.1) at baseline and did not change during the project (IRR 1.019, 95%CI 0.985-1.053, p = 0.2812). Based on data for 8523 patients; the mortality was 30.4% (95%CI 27.4-33.6) at baseline, and decreased monthly during the project by 1.6% (IRR 0.984, 95%CI 0.973-0.996, p = 0.0067). A national quality improvement collaborative was associated with improvements in daily care processes. These changes were associated with a reduction in mortality but not VAEs. Registration The study is registered in clinicaltrials.gov (NCT03790150).

Abstract Background Noninvasive respiratory support is frequently needed for patients with acute hypoxemic respiratory failure due to coronavirus disease 19 (COVID-19). Helmet noninvasive ventilation has multiple advantages over other oxygen support modalities but data about effectiveness are limited. Methods In this multicenter randomized trial of helmet noninvasive ventilation for COVID-19 patients, 320 adult ICU patients (aged ≥14 years or as per local standards) with suspected or confirmed COVID-19 and acute hypoxemic respiratory failure (ratio of arterial oxygen partial pressure to fraction of inspired oxygen < 200 despite supplemental oxygen with a partial/non-rebreathing mask at a flow rate of 10 L/min or higher) will be randomized to helmet noninvasive ventilation with usual care or usual care alone, which may include mask noninvasive ventilation, high-flow nasal oxygen, or standard oxygen therapy. The primary outcome is death from any cause within 28 days after randomization. The trial has 80% power to detect a 15% absolute risk reduction in 28-day mortality from 40 to 25%. The primary outcome will be compared between the helmet and usual care group in the intention-to-treat using the chi-square test. Results will be reported as relative risk and 95% confidence interval. The first patient was enrolled on February 8, 2021. As of August 1, 2021, 252 patients have been enrolled from 7 centers in Saudi Arabia and Kuwait. Discussion We developed a detailed statistical analysis plan to guide the analysis of the Helmet-COVID trial, which is expected to conclude enrollment in November 2021.
