Music education is a subject that is generally thought to have much physical activity involved. However, virtual learning has been mandatary applied to most schools worldwide due to the COVID-19 pandemic. The landscape of music learning has had to be switched to online distance learning (ODL), where students learn music virtually using technological tools. Gifted students are among those affected by the implementation of music ODL throughout 2020. Thus, the purpose of this study is to identify the effectiveness of music ODL on gifted students' motivation. The researchers framed this quantitative study by involving 81 secondary gifted students, aged 13 years, from 13 states in Malaysia. The sample was selected through random sampling, and a preexperimental design was applied to conduct the study. Respondents had been exposed to the music ODL intervention for a month. Data were collected through an adapted questionnaire, namely, the MUSIC Inventory, with a five-point scale. Data were further analysed by descriptive and inferential statistics, integrating two-way MANOVA, using SPSS Statistics version 23. Results reveal that an ODL approach to music classes is significantly effective to enhance gifted students' motivation domains of empowerment, usefulness, success, interest, and caring. Yet, no significant difference was found in gifted students' genders and locations on the four domains. Different approaches in music teaching could be further explored for music ODL to gifted students in future studies.

Anti-N-methyl-D-aspartate receptor (NMDAr) encephalitis is a prevalent autoimmune condition marked by diverse neuropsychiatric symptoms, primarily impacting young females. The exact mechanisms underlying the development of NMDAr encephalitis have not been fully elucidated. Nonetheless, studies have demonstrated that auto-antibodies targeting the NR1-NR2 subunits of the NMDAr can trigger receptor dysfunction within the central nervous system, thus giving rise to the associated symptoms. Notably, an association exists between NMDAr encephalitis and an underlying neoplastic condition, with approximately 38% of cases exhibiting this paraneoplastic relationship with ovarian teratomas being the most commonly associated malignancy.While the association between NMDAr encephalitis and renal cell carcinoma (RCC) is exceedingly rare. This case report presents the clinical scenario of a 20-year-old female patient diagnosed with NMDAr encephalitis in conjunction with RCC discovered incidentally on a CT abdomen and pelvis performed to rule out an ovarian teratoma. The presented case underscores the importance of adopting a multidisciplinary approach in the diagnosis and treatment of NMDAr encephalitis, particularly when it is linked to an underlying malignancy. Furthermore, it emphasizes the significance of expanding our understanding of the molecular pathogenesis of NMDAr encephalitis to enhance patient care and optimize clinical outcomes. Additionally, a comprehensive review of the existing literature is included, summarizing all reported malignancies associated with NMDAr encephalitis.

Summary:. Lower extremity reconstruction with free flaps in patients with only peroneal artery runoff remains a challenge. Here, we present a novel technique for reconstruction of medial defects in the distal leg using a medial approach to the peroneal artery and a short interposition vein graft anastomosed end to side to the peroneal artery. A retrospective, single-center study was performed including all patients who underwent lower extremity reconstruction with free flaps anastomosed to the peroneal artery using a mini vein graft from November 2020 to March 2022. The primary outcome measure was limb salvage. Secondary endpoints were flap survival and postoperative complications. Seven patients received lower extremity free flap reconstruction with a mini vein graft to the peroneal artery. Flap loss rate was 0%. Limb salvage was achieved in five patients (71%). At 6-month follow-up, all patients were ambulatory. One patient died 1 month after surgery due to heart failure. Mini vein graft to the peroneal artery allows reliable and safe free flap reconstruction of distal leg defects in patients with only peroneal artery runoff.

Mycotic aneurysms (MA) are a rare but severe complication of systemic infections, carrying a high risk of rupture, hemorrhage, sepsis, and potential multiple organ failure. Intracranial arteries are often affected and present a significant mortality risk due to cerebral bleeding and ischemic strokes. In this paper we describe the case of a 23-year-old female patient who presented with a sudden onset of right hemiparesis, followed by loss of consciousness. Cerebral imaging revealed multiple infarcts in both hemispheres and intracranial hemorrhage secondary to ruptured pseudoaneurysms. On transthoracic echocardiogram, she was found to have a left ventricular cardiac cyst with mobile vegetations potentially responsible for mycotic aneurysms and cerebral strokes. The patient underwent endovascular embolization for the mycotic aneurysms and cardiac surgery for the left ventricular cyst with satisfying clinical outcomes. Postsurgical analysis revealed the cyst to be of hydatid (Echinococcus) origin.

Sonic pressure wave should be taken into consideration in all ballistic injury. We review a young gentleman with ballistic injury of his lateral chest wall. The bullet trajectory passed through the lateral chest wall. Chest radiograph shows a wedge-shaped consolidation adjacent to the wound with blunted right costophrenic angle. Subsequent CT scan confirms the consolidation adjacent to the bullet trajectory. This case report emphasizes on value of CT in ballistic chest trauma and indirect injury caused by the sonic pressure wave of the bullet.

Abstract: Objectives: Pregnancy at high altitudes is relatively challenging because of hypobaric hypoxia, which is associated with a smaller uterine artery diameter and diminished blood flow. Here, we investigated the histopathological characteristics of early pregnancy disorders among pregnant women living in a high-altitude region (approximately 2200 m above sea level). Methods: This cross-sectional study used retrospective data collection from a single tertiary hospital in a high-altitude region in KSA. Age and histopathology were analyzed in 495 women diagnosed with early pregnancy disorders (mainly miscarriage) in 2018–2020. Results: Approximately one-fifth of pregnancies in this high-altitude region were lost before 24 weeks’ gestation, whereas 1150/6044 experienced miscarriage; 495 samples from those participants were sent for histopathological analysis. A total of 269 (54.34%) patients were younger than 35 years. Missed miscarriages accounted for 49.3% of miscarriages, followed by inevitable miscarriages (34.2%), which had a relatively higher frequency among mothers older than 35 years. The correlation between age and inevitable miscarriage was significant; ectopic pregnancy was diagnosed in 6.8%, molar pregnancy was detected in 6.26%, and blighted ovum was observed in 3.4%. Conclusion: The miscarriage rate in this high-altitude region was 19% of all pregnancies. Approximately half of the affected women were in their 30s. Missed miscarriage cases were relatively high in this region. The percentage of molar pregnancy was higher than those reported in prior studies, thus suggesting a need for monitoring and genetic workup practices. Furthermore, studies involving a larger population at high altitudes will be crucial for further risk assessment in addition to national studies on women living at sea level.

In recent years, research on the epoxidation of fatty acids has attracted considerable attention due to the growing demand for eco-friendly epoxides generated from vegetable oils. Commercially available epoxides are primarily derived from petroleum and animal fats, which are non-environmentally friendly sources. Epoxide is a crucial chemical precursor for the manufacture of alcohols, glycols, and polymers such as polyesters and epoxy resin. The optimal process parameters were determined using the one factor at a time (OFAT) technique. This study's purpose is to identify the optimal process parameter for agitation speed in relation to the oxirane ring opening of epoxidized oleic acid. The result at 100 rpm and sulfuric acid as catalyst are the optimal process setting for achieving maximal relative oxirane conversion (93 %). Then, the ring opening formation's identity was validated using Fourier Transform Infrared (FTIR).

Purpose: This study examined academic motives to enter university-industry collaboration (UIC) and how they affect collaboration performance. Given that UIC performance is context-dependent, we also explored the moderating role of relationship governance. Design/methodology/approach: The study population was academics working at a public research university while collaborating with industry. Data were collected through a cross-sectional survey. The measurement items were adapted from previous studies. Exploratory factor analysis and confirmatory factor analysis were conducted using IBM SPSS statistics 26 (SPSS 26). This study utilized a hierarchical moderated regression analysis to examine the research model. Findings: The results indicated that government and institutional policies and knowledge generation and dissemination are critical indicators of necessity that motivate academics to enter UIC and positively influence performance outcomes. Different governance mechanisms also play varying roles in the relationship between motivation and UIC performance. Practical implications: Institutional programs designed to encourage academics to collaborate with industry should consider the types of academic motivation and carefully manage collaboration efficiency using various kinds of relationship governance. Originality/value: This study contributes to existing knowledge by determining how different relationship governance mechanisms moderate the relationship between academic motivation and collaboration performance.

Background:. The demand for augmentation-mastopexy surgery without using implants has significantly increased over the years. Fat transfer offers an alternative method, but some patients do not favor this procedure either. The purpose of this study was to evaluate the versatility of using a lateral-based mammary flap as an “auto-implant” for enhancing the breast mound for patients undergoing primary mastopexy. Method:. This retrospective study was performed between February 2016 and April 2019, including 36 female patients (72 breasts). Our technique involves using the inferior breast tissue by elevating the lateral-based dermoglandular flap that was moved cranially with a 90 degree rotation in a conical shape within the created pocket to refill the superior and central mound. Result:. The mean nipple projection was 11.2 after 36 months postoperative compared with 5.2 before surgery. The mean ± SD of pre- and postoperative measurements for the lower pole zone were 80.2 ± 10.5 and 50.1 ± 6.4, and those for the upper pole zone were 40.3 ± 9.5 and 63.9 ± 6.5, respectively. The distance of breast mound elevation after the surgical procedure ranged from 5.30 to 9.55 cm, with a mean of 7.90 cm. Conclusions:. The lateral-based mammary flap acts like an implant that helps shape and augment the breast, enhances the mammary projection, and restores the breast contour without requiring a synthetic implant or fat grafting. It is a reliable technique with high patient satisfaction but is unsuitable for patients with insufficient breast volume.

Objectives . To evaluate carotid artery intima-media thickness (CIMT) and lipid profile in children with epilepsy on long-term antiepileptic drug (AED) monotherapy. Methods . We included 60 children with epilepsy receiving valproate, carbamazepine, or levetiracetam monotherapy and 60 controls. A high-resolution B-mode ultrasound was used to measure (CIMT). Measurement of serum lipids was done. Results . Patients on valproate (0.44 ± 0.03, P ≤ .001), carbamazepine (0.43 ± 0.03with P ≤ .001), and levetiracetam (0.44 ± 0.02 with P ≤ .001) monotherapy showed significantly higher CIMT compared to controls. CIMT was correlated with age ( P = .041, r = .112) AEDs{valproate ( P = .005, r = .731), carbamazepine ( P = .038, r = .365), and levetiracetam ( P = .036, r = .155)}, duration of treatment ( P = .001, r = .313), TC( P = .001, r = .192), TG ( P = .014, r = .018), and LDL ( P = .001, r = .219). HDL ( P = .003, r = −.126). Seizure severity and Apo A1 were insignificantly involved. Conclusion . Long-term monotherapy with valproate, carbamazepine, and levetiracetam in epileptic children was associated with significant abnormalities in CIMT.

Objective: To assess whether baseline pulmonary artery diameter (PAD), obtained from noncontrast nongated computed tomography (NCCT), can be associated with coronavirus disease 2019 (COVID-19) outcomes. Patients and Methods: This is a retrospective study of patients hospitalized with COVID-19 admitted to Hôtel-Dieu de France university hospital (Beirut, Lebanon) between March 1, 2020 and March 1, 2021. Pulmonary artery diameter was measured at baseline NCCT. Various outcomes were assessed, including hospital length of stay, intensive care unit admission, invasive mechanical ventilation, mortality, and Post–COVID-19 Functional Status scale at discharge and at 2-month follow-up. Results: Four hundred sixty-five patients underwent baseline NCCT, including 315 men (67.7%) with a mean age of 63.7±16 years. Baseline PAD was higher in critically ill patients admitted to the intensive care unit (mean difference, 0.8 mm; 95% CI, 0.4-1.59 mm) and those receiving invasive mechanical ventilation (mean difference, 1.1 mm; 95% CI, 0.11-2.04 mm). Pulmonary artery diameter at baseline correlated significantly with hospital length of stay (r=0.130; P=.005), discharge status (r=0.117; P=.023), and with Post–COVID-19 Functional Status scale at 2-month follow-up (r=0.121; P=.021). Moreover, multivariable logistic regression showed that a PAD of 24.5 mm and above independently predicted in-hospital all-cause mortality remained unaffected in patients with COVID-19 (odds ratio, 2.07; 95% CI, 1.05-4.09). Conclusion: Baseline PAD measurement using NCCT can be a useful prognostic parameter. Its measurement can help to identify early severe cases and adapt the initial management of patients hospitalized with COVID-19.

Background The overall poor prognosis in pancreatic cancer is related to late clinical detection. Early diagnosis remains a considerable challenge in pancreatic cancer. Unfortunately, the onset of clinical symptoms in patients usually indicate advanced disease or presence of metastasis. Analysis and Results Currently, there are no designated diagnostic or screening tests for pancreatic cancer in clinical use. Thus, identifying risk groups, preclinical risk factors or surveillance strategies to facilitate early detection is a target for ongoing research. Hereditary genetic syndromes are a obvious, but small group at risk, and warrants close surveillance as suggested by society guidelines. Screening for pancreatic cancer in asymptomatic individuals is currently associated with the risk of false positive tests and, thus, risk of harms that outweigh benefits. The promise of cancer biomarkers and use of ‘omics’ technology (genomic, transcriptomics, metabolomics etc.) has yet to see a clinical breakthrough. Several proposed biomarker studies for early cancer detection lack external validation or, when externally validated, have shown considerably lower accuracy than in the original data. Biopsies or tissues are often taken at the time of diagnosis in research studies, hence invalidating the value of a time-dependent lag of the biomarker to detect a pre-clinical, asymptomatic yet operable cancer. New technologies will be essential for early diagnosis, with emerging data from image-based radiomics approaches, artificial intelligence and machine learning suggesting avenues for improved detection. Conclusions Early detection may come from analytics of various body fluids (eg ‘liquid biopsies’ from blood or urine). In this review we present some the technological platforms that are explored for their ability to detect pancreatic cancer, some of which may eventually change the prospects and outcomes of patients with pancreatic cancer.

OBJECTIVES:. Antipsychotic medications are frequently prescribed to critically ill patients leading to their continuation at transitions of care thereafter. The aim of this study was to generate evidence-informed consensus statements with key stakeholders on antipsychotic minimization and deprescribing for ICU patients. DESIGN:. We completed three rounds of surveys in a National modified Delphi consensus process. During rounds 1 and 2, participants used a 9-point Likert scale (1—strongly disagree, 9—strongly agree) to rate perceptions related to antipsychotic prescribing (i.e., experiences regarding delivery of patient care), knowledge and frequency of antipsychotic use, knowledge surrounding antipsychotic guideline recommendations, and strategies (i.e., interventions addressing current antipsychotic prescribing practices) for antipsychotic minimization and deprescribing. Consensus was defined as a median score of 1–3 or 7–9. During round 3, participants ranked statements on antipsychotic minimization and deprescribing strategies that achieved consensus (median score 7–9) using a weighted ranking scale (0–100 points) to determine priority. SETTING:. Online surveys distributed across Canada. SUBJECTS:. Fifty-seven stakeholders (physicians, nurses, pharmacists) who work with ICU patients. INTERVENTIONS:. None. MEASUREMENTS AND MAIN RESULTS:. Participants prioritized six consensus statements on strategies for consideration when developing and implementing interventions to guide antipsychotic minimization and deprescribing. Statements focused on limiting antipsychotic prescribing to patients: 1) with hyperactive delirium, 2) at risk to themselves, their family, and/or staff due to agitation, and 3) whose care and treatment are being impacted due to agitation or delirium, and prioritizing 4) communication among staff about antipsychotic effectiveness, 5) direct and efficient communication tools on antipsychotic deprescribing at transitions of care, and 6) medication reconciliation at transitions of care. CONCLUSIONS:. We engaged diverse stakeholders to generate evidence-informed consensus statements regarding antipsychotic prescribing perceptions and practices that can be used to implement interventions to promote antipsychotic minimization and deprescribing strategies for ICU patients with and following critical illness.

Enteric duplications (EDs) are rare congenital anomalies that result from defect during embryonic development of the gut. Although EDs can literally occur at any part of the gastrointestinal tract, ileocecal duplication is the commonest type followed by colorectal type. Morphologically, EDs are mostly cystic in nature; tubular duplications are uncommon. We report radiological diagnostic challenges encountered in dealing with a 10 month-old infant who presented with chronic constipation, progressive abdominal distension, and voiding difficulty for several weeks followed by colicky abdominal pain for three days. After a series of radiological procedures, a diagnosis of tubular colorectal duplication was made. The duplicated segment was loaded with impacted feces which exerted pressure effect on the rectum and urinary bladder. The case was treated surgically through laparoscopic procedure that included fenestration and stapling of the duplicated bowel followed by irrigation. Postoperatively, the child was followed up half-yearly for three years and was found to remain symptom-free. This case exemplifies the challenges a radiologist may experience while dealing with a case presenting with features of as acute-on-chronic intestinal obstruction and voiding difficulty.

Abstract. Rationale:. Since mass-scale severe acute respiratory syndrome coronavirus 2 vaccination, there have been case reports of several immune-mediated reactions, including new-onset and flares of glomerular disorders following immunization with mRNA coronavirus disease 2019 vaccines. Here, we report two cases, the first to our knowledge, of relapsing cryoglobulinemic vasculitis with new-onset severe renal involvement following mRNA coronavirus disease 2019 vaccination. Patient concerns:. The relapse of the cutaneous and the new onset of severe renal involvement of cryoglobulinemic vasculitis occurred three weeks after the second dose of the mRNA Moderna coronavirus disease 2019 vaccination and two days after the first dose of mRNA Pfizer coronavirus disease 2019 vaccination in the first and second patient, respectively. Diagnosis:. Kidney biopsies were performed. The first pacient's kidney biopsy showed a membranoproliferative pattern of glomerular injury with extensive mesangial and endocapillary hypercellularity, while severe endothelial swelling, loss of fenestrations and widening of subendothelial space were identified by electron-microscopy. The second patient's kidney biopsy was consistent with cryoglobulin associated membrano-proliferative pattern of glomerular injury. Interventions:. Our patients were managed with a combination of immunosuppressants consisting of corticosteroids, Cyclophosphamide and Rituximab with a favourable outcome at the end of the induction period. Outcomes:. Clinical and immunological response was achieved in both patients after four months of follow-up. Lessons:. The temporal association of the relapse of the cryoglobulinemic vasculitis to mRNA coronavirus disease 2019 vaccination suggest that the vaccine might have been a trigger for the reactivation of the disease in our cases. This possible association should be acknowledged by physicians in order to provide optimal monitoring and treatment in case of reactivation of the disease post-immunization.

Learning loss pertains to the decline or regression in knowledge and abilities, as well as setbacks in academic advancement. This phenomenon typically arises from prolonged interruptions or gaps in the pupil's educational journey. Learning loss can be observed in diverse manifestations due to many factors. One example that can be illustrated is the disruption of formal education due to the COVID-19 pandemic that struck the world in 2019. As a result, this phenomenon has impacted students' academics, whether at the school level or higher education institutions, especially primary school students, thus causing learning poverty. This scoping review aims to identify the degree of reading literacy among primary school students and to investigate the factors that contribute to the learning losses of primary school students from the reading aspect. Four databases, including Scopus, Education Resources Information Center (ERIC), Bielefeld Academic Search Engine (BASE), and Directory of Open Access Journals (DOAJ), were used in this research, which found 40 articles for eligibility. Only 20 articles are eligible for analysis and reference after the exclusion and inclusion process for data collection. The findings show that learning losses have impacted the education sector, leading to poverty, especially among primary school children. [ABSTRACT FROM AUTHOR]

The tailoring of the surface properties of cellulose nanocrystals (CNCs) to meet various requirements in environmental, food, and material areas has always been of great interest. In this study, the surface chemistry of CNCs was noncovalently modified by cetyltrimethylammonium bromide (CTAB), followed by characterizations and an investigation into its application as a coating material for interfacial interaction over various substrates. Due to the CTAB modification, the surface charge of the CNCs was neutralized, resulting in an increased size of each nanocrystal at the aqueous status and the aggregated microfibers when dried up. The CTAB modification not only decreased the crystallinity of the samples from 48.57% to 9.12%, but also reasonably hydrophobized the CNCs and decreased their total surface energy. Finally, the adsorption behavior of the CNCs and CTAB-CNCs over nonionic, anionic, and cationic polymers was investigated by ellipsometry. Based on the thickness of the CNC and CTAB-CNC layers over 2-Hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), and polyethyleneimine (PEI), we proposed that the adsorption behavior was overall influenced by electrostatic interaction, hydrogen bonding, and van der Waals forces, and the thickness of the adsorbed layers could be impacted by both the surface charge and the size of the crystals.

Outdoor learning encompasses a wide range of educational activities, from local natural play areas to formal school curriculum classes. Despite growing evidence of its benefits, outdoor learning is still underutilized in Malaysia's early childhood education system. Hence, this study aims to investigate preservice teachers' perceptions of the impact of outdoor learning on children's well-being since future teachers' perception is the most important indicator in predicting their intention to use it in the future. A quantitative approach was used, and the questionnaire was distributed to 63 pre-service teachers studying at Universiti Selangor, Malaysia. Based on the findings, the majority of respondents agree that outdoor learning benefits children's well-being, especially their social and psychosocial well-being. Thus, this study provides insight into the significance of outdoor learning on children's learning experiences and that it should be utilized more frequently in the classroom. [ABSTRACT FROM AUTHOR]
