- Abstract
The COVID-19 pandemic disrupted traditional K-12 education worldwide, forcing a rapid shift to emergency remote teaching and learning. This dissertation utilizes a three-article approach and investigates the multifaceted impact of the pandemic on urban charter high school students and their principals in under-resourced communities. The first article employs the Community of Inquiry (CoI) framework to explore the relationships between social presence, engagement, and achievement of students in asynchronous online classes during the pandemic. The second article, framed by Transactional Distance Theory (TDT), delves into factors influencing students' online learning experiences by using quantitative and qualitative methods to capture the nuances of their perspectives. The third article employs an equity-oriented crisis leadership framework to examine how urban school principals in underprivileged communities perceived and navigated online education practices during the pandemic. Data for the first and second articles are drawn from 395 high school students in a nonprofit charter school network (CSN) in the Midwestern United States, utilizing de-identified secondary data. The third article relies on qualitative data gathered through semi-structured interviews with 11 high school principals in the CSN's high schools. The research contributes to the literature by providing empirical insights into the impact of the pandemic on student learning outcomes, social presence, and engagement in online education as well as the challenges faced by school principals. The study's contextualization within under-resourced urban communities in the Midwest enhances the understanding of the experiences of students and principals in high-needs areas. The findings offer practical implications for educators and policymakers, emphasizing the importance of social presence, student engagement, and effective leadership in mitigating the challenges posed by emergency remote teaching. As K-12 schools face ongoing uncertainties, this research provides valuable insights for better preparedness and resilience in high-needs communities.

A wide array of clinical manifestations follow infection with Coccidioides immitis or Coccidioides posadasii, ranging from asymptomatic infection to life-threatening pulmonary disease or extrapulmonary dissemination and meningitis. Epidemiological studies require consistent definitions of cases and their comparative clinical features. Understanding host and pathogen determinants of the severity of coccidioidomycosis also requires that specific clinical features (such as coccidioidal meningitis) and their overlap be precisely defined and quantified. Here we propose a system for categorization of outcomes of coccidioidomycosis in individuals who are not overtly immunocompromised that harmonizes clinical assessments during translational research of this increasingly common disease.

Purpose: The aim of this study was to investigate whether there is a difference in hand bone mineral density (BMD) between patients with traumatic hand injuries and healthy volunteers during the immobilization process, as well as to examine the change in BMD during follow-up and the effect of denervation on BMD. In addition, we aimed to compare the BMD in the dominant and nondominant hands. Methods: The study involved patients aged 18–55 years who had undergone surgery for hand tendon injuries (TIs), with or without accompanying nerve injury, and subsequently sought rehabilitation at our outpatient clinic. The study groups were comprised patients with TI, those with tendon and nerve injury (TNI), and healthy volunteers. Results: The study examined 24 patients with TI, 23 with TNI, and 31 healthy volunteers. In the healthy control group, the BMD of the dominant hand was significantly higher than that of the nondominant hand (P < 0.001). At 4 weeks, there was no significant decrease in BMD observed in the TI and TNI groups compared to controls (P > 0.05). However, at the 4th month, both groups showed a significant decrease in BMD, with the TNI group exhibiting higher changes (P < 0.05). Injuries to the dominant hand did not result in significant changes in BMD at 4 weeks and 4 months (P > 0.05). However, a significant decrease in BMD was observed in injuries to the nondominant hand compared to controls at 4 months (P < 0.05). Notably, nondominant hand TNI patients experienced a significant reduction in BMD during the 4th month compared to the 4th week (P < 0.05). In addition, a significant correlation (r = 0.567) was found between grip strength and BMD value in the 4th month of patients with hand injuries. Conclusion: In patients with traumatic hand injuries, nondominant hand injury and/or nerve injury may lead to a decrease in BMD in addition to immobilization.

Background Electrodiagnostic testing (EDX) is important in the diagnosis and follow-up of neuropathic and myopathic diseases. This study aimed to demonstrate the compatibility between clinical prediagnosis and electrophysiological findings. Methods EDX results from 2004 to 2020 at the physical medicine and rehabilitation (PM&R) clinic were screened. Tests with missing data, reevaluation studies, and cases of peripheral facial paralysis were excluded. The clinical prediagnosis and EDX results were recorded, and their compatibility was evaluated. Results A total of 2,153 tests were included in this study. The mean age was 49.0±13.9 years and 1,533 of them (71.2%) were female. The most frequently referred clinic was the PM&R clinic (90.0%). Numbness (73.6%) was the most common complaint, followed by pain (15.3%) and weakness (13.9%). The most common prediagnosis was entrapment neuropathy (55.3%), radiculopathy (16.1%), and polyneuropathy (15.7%). Carpal tunnel syndrome was the most frequently identified type of entrapment neuropathy (78.3%). Six hundred and seventy EDX results (31.1%) were within normal limits. While the EDX results were consistent with the prediagnosis in 1,328 patients (61.7%), a pathology different from the prediagnosis was detected in 155 patients (7.2%). In the discrepancy group, the most common pathologies were entrapment neuropathy (51.7%), polyneuropathy (17.3%), and radiculopathy (15.1%). The most common neuropathy type was carpal tunnel syndrome (79.3%). Conclusion After adequate anamnesis and physical and neurological examinations, requesting further appropriate tests will increase the prediagnosis accuracy and prevent unnecessary expenditure of time and labor.

Abstract Objectives In the interpretation of panoramic radiographs (PRs), the identification and numbering of teeth is an important part of the correct diagnosis. This study evaluates the effectiveness of YOLO-v5 in the automatic detection, segmentation, and numbering of deciduous and permanent teeth in mixed dentition pediatric patients based on PRs. Methods A total of 3854 mixed pediatric patients PRs were labelled for deciduous and permanent teeth using the CranioCatch labeling program. The dataset was divided into three subsets: training (n = 3093, 80% of the total), validation (n = 387, 10% of the total) and test (n = 385, 10% of the total). An artificial intelligence (AI) algorithm using YOLO-v5 models were developed. Results The sensitivity, precision, F-1 score, and mean average precision-0.5 (mAP-0.5) values were 0.99, 0.99, 0.99, and 0.98 respectively, to teeth detection. The sensitivity, precision, F-1 score, and mAP-0.5 values were 0.98, 0.98, 0.98, and 0.98, respectively, to teeth segmentation. Conclusions YOLO-v5 based models can have the potential to detect and enable the accurate segmentation of deciduous and permanent teeth using PRs of pediatric patients with mixed dentition.

Contrast enhancement is very important in terms of assessing images in an objective way. Contrast enhancement is also significant for various algorithms including supervised and unsupervised algorithms for accurate classification of samples. Some contrast enhancement algorithms solve this problem by addressing the low contrast issue. Mean and variance based sub-image histogram equalization (MVSIHE) algorithm is one of these contrast enhancements methods proposed in the literature. It has different parameters which need to be tuned in order to achieve optimum results. With this motivation, in this study, we employed one of the most recent optimization algorithms, namely, coot optimization algorithm (COA) for selecting appropriate parameters for the MVSIHE algorithm. Blind/referenceless image spatial quality evaluator (BRISQUE) and natural image quality evaluator (NIQE) metrics are used for evaluating fitness of the coot swarm population. The results show that the proposed method can be used in the field of biomedical image processing., Comment: 14 pages

Coccidioides species are thermally dimorphic fungi found in geographically defined areas of the Western Hemisphere. The primary portal of entry is respiratory, with symptomatic pneumonic diseases as the most common presentation. Subsequent pulmonary complications as well as extrapulmonary metastatic infection may occur, either of which may be the presenting disease manifestation. Cavitary lung disease may be found incidentally or when investigating symptoms such as cough or hemoptysis. This study aims to explore the spectrum of coccidioidal cavities and the evaluation and management in a cohort of patients seen at Kern Medical over the last 12 years.

Background/Aims: Hepatocellular carcinoma is a major cause of mortality and morbidity in both cirrhotic and non-cirrhotic patients, and most patients are suitable for locoregional and/or systemic therapy at the time of diagnosis. In this study, we aimed to determine the efficacy and safety of transarterial radioembolization in elderly patients. Materials and Methods: Patients diagnosed with hepatocellular carcinoma between 2013 and 2022 were screened retrospectively. The patients were divided into 2 groups: the elderly (age ≥70 years) and the young (age .05). Hepatitis B was the most common cause in both groups. There were no significant differences between groups with regard to morphological features of tumors [tumor focality (single; 62.2% and 60.7%, respectively) and maximal tumor diameter (6.9 and 6.55 cm, respectively)], transarterial radioembolization responses (51.1% and 39.3%, respectively), survival (9 and 8.5 months), and both early and late side effects (P > .05). Age was not found to be an effective factor in transarterial radioembolization response (P > .05). Conclusion: No differences in the safety and efficacy of transarterial radioembolization were observed between the groups. In addition, it was observed that age was not a predictive factor for adverse events. In elderly patients in the frail group, it should be considered that age alone should not be seen as a limitation in the transarterial radioembolization decision.

Abstract The ABO and D antigen status of red blood cells (Rh blood grouping systems) are important hematological classification systems that categorize blood groups according to the presence or absence of certain erythrocytic antigens. These antigens affect the outcomes of blood transfusions as well as various hematological and immunological diseases. We aimed to study ABO and Rh blood group distribution among pregnant women visiting the antenatal care clinic at Jordan University Hospital (JUH) in Amman, Jordan. A retrospective analysis of all pregnant women delivering at the Jordan University Hospital (JUH) between October 1, 2016, and September 31, 2021. ABO and D antigen status of red blood cells (Rh blood groups) were summarized and documented. 20,136 pregnant women data were analyzed, the O blood group was the most prevalent (n = 7840, 38.9%), followed by A (n = 7506, 37.3%). For the D antigen status, the Rh-positive (Rh+) category was the most common (n = 18,159, 90.2%). For the (O) blood group; O-Rh+ type was the most prevalent (90.1%). Determining the blood group type accurately helps eliminate the critical consequences of both ABO and Rh incompatibility and offers clinicians an opportunity to take timely prophylactic measures. In our analyses O and Rh+ blood groups were the most prevalent.

Computer Science - Networking and Internet Architecture - Abstract
This study aims to enhance spatial reuse by using the new features of IEEE 802.11ax WLANs. Since the wireless medium is a shared medium and there may be multiple basic service sets (BSS) in the same vicinity, BSSs may overlap, and interference occurs. In this situation, BSSs cannot transmit simultaneously due to the exposed node problem. The IEEE 802.11ax standard has a couple of mechanisms to resolve these spectral efficiency problems. One of the most effective mechanisms that address these problems is the overlapping BSS preamble detection (OBSS/PD) mechanism. OBSS/PD mechanism uses the color mechanism to distinguish OBSS signals. By using a signal threshold, the mechanism can ignore some of the signals, which cause interference. In this paper, we propose a rate-adaptive dynamic OBSS/PD threshold algorithm that tracks the changes in transmission rate and dynamically adjusts the threshold step by step considering the changes., Comment: 6 figures

Coccidioidomycosis is the second most common endemic fungal infection in the United States. Prior descriptions of coccidioidal peritonitis include only single cases. We describe 17 new cases previously unreported from healthcare institutions in California. The majority of cases presented with nonspecific abdominal complaints. PubMed and Google Scholar were searched for additional case series and only single case reports and reviews of single cases were found. The diagnosis was confirmed by culture or histopathology and/or serology in each patient. All patients were treated with anti-fungal therapy. This case series demonstrates that coccidioidal peritonitis may be asymptomatic or present with only subtle abdominal symptoms. In a minority of our patients, the diagnosis was established incidentally during surgery. Based on this series, the overall outcome of coccidioidal peritonitis is favorable with long-term triazole treatment. The term cure is not usually used in disseminated coccidioidal disease because of the risk of late relapse.

A 49-year-old man with no significant past medical history received dexamethasone as part of his treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Less than 3 weeks later, the patient developed acute respiratory distress syndrome. Radiological and serological testing led to a diagnosis of acute hypoxic miliary coccidioidomycosis. A 52-year-old man with a past medical history of chronic kidney disease (CKD) was treated with prednisone for focal segmental glomerulosclerosis (FSGS). Within 2 weeks, this patient developed bilateral lower extremity weakness. Radiology, serology, and lumbar puncture proved a diagnosis of reactivated coccidioidomycosis with miliary pattern and coccidioidomycosis meningoencephalitis with arachnoiditis. Whether treatment with glucocorticoids caused reactivation of coccidioidomycosis is discussed in this case series.

Coccidioidomycosis (CM) is a fungal disease that results from inhalation of spores of Coccidioides immitis and C posadasii. If symptomatic, disease primarily manifests as community-acquired pneumonia; however, additional pulmonary manifestations such as pleural effusion, empyema, and cavitation may occur. Diabetic patients have an increased risk of severe and cavitary CM. Cavitary disease may erode vasculature and pulmonary parenchyma leading to further complications. Furthermore, chronic cavities can become colonized as well and develop superimposed infections. This is a case of cavitary CM in uncontrolled diabetic nonadherent to treatment presenting with hemoptysis and mycetoma.

Meningococcal pneumonia (MP) is a rare manifestation of meningococcal disease. The MP was first described in 1907 when Neisseria meningitidis (NM) isolates were identified in sputum samples obtained from soldiers with pneumonia. Preceding and concurrent viral infections constitute a major risk for MP. During the 1918-1919 influenza pandemic, a significant increase in MP cases were reported in patients with preceding influenza infection. Despite the end of the last H1N1 influenza pandemic in 2010, seasonal influenza infections still pose a risk for simultaneous MP. History appears to be repeating itself with concomitant bacterial and viral coinfection amid the current SARS-CoV-2 pandemic. Herein presented is a unique case of an elderly woman who presented with, to the best of our knowledge, the first reported case of possible concurrent SARS-CoV-2 and MP infections.

Coccidioidomycosis (CM) is a fungal infection endemic to the southwestern United States with a wide range of clinical presentations depending on the infected organ systems. Most infections are asymptomatic. Coccidioidomycosis causes a primary pulmonary infection and when symptoms occur, they most often resemble community-acquired pneumonia. One percent of cases disseminate, typically via hematogenous or lymphatic spread. It is in these cases that more severe symptoms may present and potentially overlap with those characteristics of other systemic illnesses. This is a case of CM disseminated to lymph nodes in a 24-year-old man with concomitant metastatic embryonal carcinoma. It is difficult to identify the primary etiology for many components of this patient's presentation, including diffuse lymphadenopathy and multiple pulmonary nodules. Furthermore, the relationship between these 2 concurrent disease processes is not entirely clear. Factors that may contribute include the well-known phenomenon of locus minoris resistentiae (LMR) or potentially a shared immune failure between infectious organisms and malignant cells.

In search of selective cytotoxic compounds from Ferula species as potential leads for the treatment of various cancer diseases, a bioactivity-guided isolation study was performed on the roots of Ferula caspica M. Bieb. COLO 205 (colon), K-562 (leukemia), and MCF-7 (breast) cancer cell lines were used to monitor the cytotoxic activity of column fractions and determine the IC50 value of the active compounds. In addition to the seven known (5–11) compounds, four previously unknown compounds: kayserin A (1), kayserin B (2), 8′-epi-kayserin B angelate (3), and 3-epi-ferulin D (4) were isolated from the dichloromethane extract of the roots of F. caspica. Structure elucidation of the isolated compounds was carried out by extensive spectroscopic analyses such as 1D- and 2D-NMR spectroscopy, High-Resolution Mass Spectroscopy (HRMS), IR spectroscopy, and UV spectroscopy. Although all of the isolated compounds showed various degrees of cytotoxic activity on COLO 205, K-562, and MCF-7 cancer cell lines, the most potent compounds were identified in the following order: 1-Hydroxy-1-(1′-farnesyl)-4,6-dihydroxyacetophenone (HFDHAP, 11), 3-epi-ferulin D (3EFD, 4), and 7-desmethylferulin D (7DMFD, 6). The cytotoxic activities of all three compounds were more potent than that of the reference compound cisplatin (Cis) against all tested cancer cell lines. Still, only HFDHAP (11) was more potent than the reference compound doxorubicin (Dox) against the MCF-7 cancer cell line. The mechanism of action of these three compounds was investigated on the COLO 205 cell line. The results indicated that compounds 4, 6, and 11 trigger caspase-3/8/9 activation and suppress the anti-apoptotic protein, Bcl-xL. Molecular docking studies confirmed the interactions of the three cytotoxic molecules with the active site of the Bcl-xL protein.

Background: Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an autosomal dominant syndrome that has various expressions in each patient. Generally; NBCCS is followed by multiple nevoid basal cell carcinoma of the skin, orbital anomalies, skeletal anomalies, central nervous system anomalies and multiple odontogenic keratocysts (OK). NBCCS is usually diagnosed between the ages of 5–30 years, with multiple basal cell carcinomas of the skin and OKs in the jaws as the initial findings. The purpose of this paper is to describe and compare the radiographic findings of the OKs in NBCCS patients in the literature with additional cases. Materials and Methods: In this study, we evaluated the OKs of the patients with NBCCS in PubMed Database with 5 additional cases from our database. A total of 305 articles were found and the articles in English with full-text access were evaluated. Results: Despite all limitations for a fair discussion; we would like to state that among 59 cases that specified whether a 3D or 2D imaging modality was used, 29 cases were only interpreted with 2D data which should be avoided in OK evaluation. Discussion: According to the World Health Organization’s Classification of Head and Neck Tumours Book which was published in 2017, OKs in NBCCS has a higher chance to have small satellite cystic lesions which increase their recurrence possibility post-operatively, thus, a thorough clinical and 3D radiographic evaluation should be performed both to NBCCS patients and non-syndromic OK patients to avoid any recurrence. Conclusion: High recurrence rates of OKs should be reminded all the time. Radiographic examinations with 3D imaging modalities should be done in patients with NBCCS in order to provide a concise diagnosis and optimum treatment.

Abstract Background Emodin and aloe-emodin are two anthraquinones having positive effects in wound healing. However, their mechanism of action of wound healing is not fully understood. The MAP kinase family, which plays an active role in wound healing, is a well-characterized large family of serine/threonine kinases and regulates processes such as proliferation, oncogenesis, differentiation, and inflammation in the cell. The aim of this study is to comparatively elucidate the mechanisms of action of emodin and aloe-emodin, which are potential agents in wound healing. Methods The mechanism of the effects of emodin and aloe-emodin on cell viability and cell migration was examined using the human skin fibroblast (CCD-1079Sk) cell line. The gene expression levels of the MAP kinases (JNK, P38, ERK) in the skin fibroblast cells along with a molecular docking study analyzing their interaction potential were evaluated. Furthermore, the molecules’ effects on the lifespan of Caenorhabditis elegans were studied. Results Emodin and aloe-emodin inhibited the ATP content of the cells in a concentration dependent manner and accelerated cell migration at the lower concentrations while inhibiting cell migration in the higher concentration treatment groups. The expressions of JNK and P38 were upregulated at the low concentrations and downregulated at the higher concentrations. The molecular docking studies of the molecules gave high docking scores indicating their interaction potential with JNK and P38. C. elegans lifespan under heat stress was observed longer after 75 µM emodin and was significantly reduced after 150 µM aloe-emodin treatment. Conclusion Aloe-emodin was found to be more potent on cell viability, cell migration, gene expression levels of the MAP kinases in healthy fibroblastic skin cells, and on the lifespan of C. elegans. This study reveals the functional effects and the biological factors that interact in the wound healing process of emodin and aloe-emodin, and give a possible treatment alternative to shorten the duration of wound care.

Computer Science - Emerging Technologies ,Computer Science - Information Theory - Abstract
This survey paper focuses on modulation aspects of molecular communication, an emerging field focused on building biologically-inspired systems that embed data within chemical signals. The primary challenges in designing these systems are how to encode and modulate information onto chemical signals, and how to design a receiver that can detect and decode the information from the corrupted chemical signal observed at the destination. In this paper, we focus on modulation design for molecular communication via diffusion systems. In these systems, chemical signals are transported using diffusion, possibly assisted by flow, from the transmitter to the receiver. This tutorial presents recent advancements in modulation and demodulation schemes for molecular communication via diffusion. We compare five different modulation types: concentration-based, type-based, timing-based, spatial, and higher-order modulation techniques. The end-to-end system designs for each modulation scheme are presented. In addition, the key metrics used in the literature to evaluate the performance of these techniques are also presented. Finally, we provide a numerical bit error rate comparison of prominent modulation techniques using analytical models. We close the tutorial with a discussion of key open issues and future research directions for design of molecular communication via diffusion systems., Comment: Preprint of the accepted manuscript for publication in IEEE Surveys and Tutorials

Steroid resistance is a common condition occurring in children with nephrotic syndrome. Until now, over 50 genes involved in steroid-resistant nephrotic syndrome (SRNS) pathogenesis have been identified, among which the most prevalent are NPHS1, NPHS2, CD2AP, and PTPRO. The patterns of inheritance of SRNS are autosomal recessive, autosomal dominant, or mitochondrial, and tissues of those patients show focal segmental glomerulosclerosis (FSGS) signs in histopathological image analysis. We present a case of a 6-year-old girl who was admitted to the pediatric nephrology department due to nephrotic range proteinuria and edema of the lower leg. We started therapy with prednisone at a dose of 45 mg (60 mg/m 2 ), enalapril as a nephroprotection, and antihistamines as an additional treatment. During in-patient treatment, we detected increased blood pressure. Due to persistent proteinuria in spite of 6-week treatment with steroids at the maximal dose, we confirmed disease resistance to steroids. Additionally, FSGS signs were confirmed in kidney biopsy samples. After genetic screening for SRNS and detection of the rare gene mutation NUP93 we reduced prednisone but maintained nephroprotective treatment and administered cyclosporin A. The girl remains currently under the care of nephrologists with normal arterial blood pressure, trace proteinuria in follow-up examination, and normal kidney function. NUP93 mutation is extremely rare; therefore few cases have been described to date. The onset of the symptoms in all pediatric patients appeared before the age of 8 and they developed end stage kidney disease (ESKD). They might manifest symptoms from the other systems.

Coccidioidomycosis is a fungal infection of the Western hemisphere that is endemic to the soil in areas with limited rainfall. Human and animal infections result with inhalation of arthroconidia. Most often, this is an asymptomatic event. When illness occurs, it is primarily a pneumonic presentation. A small minority of infections eventuate in disseminated disease. Predominately, this presents as meningitis or osteoarticular or integumentary disease. Treatment may not be required for the mildest illness. Azoles are commonly prescribed. Severe infections may require amphotericin B.

Coccidioidomycosis is an infection caused by inhalation of arthroconidia of Coccidioides. Forty percent of patients will develop mild and self-limited respiratory infection, and a small fraction of these individuals will develop extrapulmonary disseminated disease. This is the case of a patient with a known history of disseminated coccidioidomycosis, who initially presented for symptoms of persistent pneumonia. On evaluation, the patient was found to have a hepatic abscess for which he underwent percutaneous drainage. Culture grew Coccidioides immitis, and the patient was treated with systemic antifungal. This is a rare case of disseminated coccidioidomycosis in the liver.

Neuropsychiatric symptoms are a common complication of COVID-19, with symptoms documented both during acute COVID-19 infection (parainfectious) and persisting or developing after the resolution of respiratory symptoms (postinfectious). Patients have presented with a variety of symptoms such as anosmia, thrombotic events, seizures, cognitive and attention deficits, new-onset anxiety, depression, psychosis, and rarely catatonia. Etiology appears to be related to disruption of regular neurotransmission and hypoxic injury secondary to systemic inflammation and cytokine storm. Although rare, catatonia and each of its subtypes have now been reported as complications of COVID-19 and therefore should be considered known to occur in both the parainfectious and postinfectious states. Diagnosis of catatonia in the context of COVID-19 should be considered when work-up for more common medical causes of encephalopathy are negative, there is no identifiable psychiatric etiology for catatonia, and there is a positive response to benzodiazepines.

Oplatka, Izhar and El-Kuran, Sultan
- Abstract
The aim of the current study was to explore Bedouin teachers' emotion management in schools that serve Bedouin students living in traditional communities in the south of Israel. Semi-structured interviews with 14 teachers from elementary schools (for Bedouin students) emphasised the central place of the local culture in shaping teachers' emotion management and the dilemmas they face between modern and traditional emotion rules. Emotion management and regulation in the Bedouin school differs largely from that in Western educational systems. Living in a society whose culture praises power, formality and masculinity, the Bedouin teacher tends to suppress emotions at work, particularly those perceived as positive in Western cultures (e.g. happiness, joy), and sometimes display those perceived in Western cultures as undesirable (e.g. anger towards students).

BackgroundTeaching hospitals have been regarded as the primary settings where doctors teach and practice high-quality medicine, as well as where medical students learn the profession and acquire their initial clinical skills. A percentage of instruction is now done over the internet or via electronic techniques. The present COVID-19 epidemic has pushed distance electronic learning (DEL) to the forefront of education at all levels, including medical institutions. ObjectiveThis study aimed to observe how late-stage medical students felt about DEL, which was put in place during the recent COVID-19 shutdown in Jordan. MethodsWe conducted a prospective, cross-sectional, web-based, questionnaire-based research study during the COVID-19 pandemic lockdown between March 15 and May 1, 2020. During this period, all medical schools in Jordan shifted to DEL. ResultsA total of 380 students responded to a request to fill out the questionnaire, of which 256 completed the questionnaire. The data analysis showed that 43.6% (n=112) of respondents had no DEL experience, and 53.1% (n=136)of respondents perceived the DEL method as user-friendly. On the other hand, 64.1% (n=164) of students strongly believed that DEL cannot substitute traditional clinical teaching. There was a significant positive correlation between the perception of user-friendliness and the clarity of the images and texts used. Moreover, there was a strong positive correlation between the perception of sound audibility and confidence in applying knowledge gained through DEL to clinical practice. ConclusionsDEL is a necessary and important tool in modern medical education, but it should be used as an auxiliary approach in the clinical setting since it cannot replace conventional personal instruction.

Coccidioidomycosis a fungal infection endemic to southwestern United States. It is caused by inhalation of spores of Coccidioides immitis. Sixty percent of infections are asymptomatic; the remaining 40% are primarily pulmonary disease. In 1:512. Bone scan showed uptake of adjacent bones in the affected joints. Superimposed bacterial infection of the wrist complicated the treatment course and delayed the start of liposomal amphotericin B. Eventually patient received 12 weeks of intravenous liposomal amphotericin-B with slow clinical improvement and then switched to oral isavuconazonium for maintenance therapy. This case shows that although disseminated polyarthritis coccidioidomycosis is very rare, clinicians should keep the diagnosis of disseminated synovial coccidioidomycosis in mind in patients with risk factors.

- Abstract
This study reveals how the classroom talk was in the bilingual classroom interaction. The classroom talk comprises teacher and pupil talk--in which they cover teacher's explanation, teacher's question, teacher's feedback, and modification to teacher's speech; as well as pupil's responses and pupil's questions. The research findings show that the language option used by the teachers in the bilingual classroom interaction was influenced by several factors, such as (1) teacher's linguistic competence, (2) the views on the roles of the two languages in the bilingual interaction (3) teacher's interpretation on the instructional language use prescribed by the school management, and (4) the teacher's educational background. The research findings on pupil talk show that the pupils generally adjusted their language option in responding to questions as the language used by the teachers in asking questions. Although the questions were translated into their mother tongue, pupils still assumed that the questions were actually in English. Similarly, the pupils strived to adjust the language of their questions as the language used by the teachers in explaining.

Background: An elective caesarean section (CS) has been associated with high anxiety scores, and there are associations between higher anxiety scores and younger age, primigravidae, higher educational level, and previous experience with anaesthesia. In this study, the aim is to measure anxiety scores associated with an elective CS using two measuring scales and identify women's characteristics and obstetrics variables that are associated with higher scores. Methods: A cross-sectional study was conducted between Nov 15, 2019 and Nov 15, 2020. Women were included if they were 18 years of age or more, had viable pregnancies, and were admitted for an elective CS. Anxiety scores were measured on admission using the visual analogue scale for anxiety (VASA) and then the State-Trait Anxiety Inventory (STAI-Y). Associated factors were studied using logistic regression analyses. Results: Three hundred women were recruited. Means (SD) for the participant's age and gestation age were 30.5 (5.7) years and 37.6 (1.4) weeks, respectively. Additionally, 29.3% of the participants having a CS were primigravidae and 62.3% were for maternal indications. Furthermore, 55%, 59%, and 61% of the women had scores above the means of VASA and STAI-S components 1 and 2, respectively.Variables that showed statistically significant associations with higher anxiety scores were that the woman's age was 25–34, the CS was for foetal indications, the choice of anaesthesia was general, and the source of information for the choice of anaesthesia was a layperson. Conclusion: Higher anxiety scores are prevalent among women admitted for an elective CS. STAI-Y and VASA correlated well, and the short VASA may replace the lengthy STAI-Y in clinical practice. Identification of women with risk factors may help in implementing strategies to reduce anxiety.
