Abstract
Background
High sedentary times (ST) is highly prevalent in patients with coronary artery disease (CAD), highlighting the need for behavioural change interventions that effectively reduce ST. We examined the immediate and medium-term effect of the SIT LESS intervention on changes in ST among CAD patients enrolled in cardiac rehabilitation (CR).

Methods
CAD patients participating in CR at 2 regional hospitals were included in this randomized controlled trial (1:1, stratified for gender and hospital). The control group received CR, whereas SIT LESS participants additionally received a 12-week hybrid behaviour change intervention. The primary outcome was the change in accelerometer-derived ST from pre-CR to post-CR and 3 months post-CR. Secondary outcomes included changes in ST and physical activity characteristics, subjective outcomes, and cardiovascular risk factors. A baseline constrained linear mixed-model was used.

Results
Participants (23% female; SIT LESS: n = 108, control: n = 104) were 63 ± 10 years. Greater ST reductions were found for SIT LESS compared to control post-CR (-1.7 (95% confidence interval (CI): -2.0; -1.4) versus − 1.1 (95% CI: -1.4; -0.8) h/day, pinteraction=0.009), but not at 3 months post-CR (pinteraction=0.61). Besides, larger light-intensity physical activity (LIPA) increases were found for SIT LESS compared to control post-CR (+ 1.4 (95% CI: +1.2; +1.6) versus + 1.0 (95% CI: +0.8; +1.3) h/day, pinteraction=0.020). Changes in other secondary outcomes did not differ among groups.

Conclusion
SIT LESS transiently reduced ST and increased LIPA, but group differences were no longer significant 3 months post-CR. These findings highlight the challenge to induce sustainable behaviour changes in CAD patients without any continued support.

Abstract
Background
Glioblastoma (GB) is recognized as one of the most aggressive brain tumors, with a median survival of 14.6 months. However, there are still some patients whose survival time was greater than 3 years, and the biological reasons behind this clinical phenomenon arouse our research interests. By conducting proteomic analysis on tumor tissues obtained from GB patients who survived over 3 years compared to those who survived less than 1 year, we identified a significant upregulation of SelK in patients with shorter survival times. Therefore, we hypothesized that SelK may be an important indicator related to the occurrence and progression of GBM.

Methods
Proteomics and immunohistochemistry from GB patients were analyzed to investigate the correlation between SelK and clinical prognosis. Cellular phenotypes were evaluated by cell cycle analysis, cell viability assays, and xenograft models. Immunoblots and co-immunoprecipitation were conducted to verify SelK-mediated ubiquitin-dependent degradation of CDK4.

Results
SelK was found to be significantly upregulated in GB samples from short-term survivors (≤ 1 year) compared to those from long-term survivors (≥ 3 years), and its expression levels were negatively correlated with clinical prognosis. Knocking down of SelK expression reduced GB cell viability, induced G0/G1 phase arrest, and impaired the growth of transplanted glioma cells in nude mice. Down-regulation of SelK-induced ER stress leads to a reduction in the expression of SKP2 and an up-regulation of β-TrCP1 expression. Up-regulation of β-TrCP1, thereby accelerating the ubiquitin-dependent degradation of CDK4 and ultimately inhibiting the malignant proliferation of the GB cells.

Conclusion
This study discovered a significant increase in SelK expression in GB patients with poor prognosis, revealing a negative correlation between SelK expression and patient outcomes. Further mechanistic investigations revealed that SelK enhances the proliferation of GB cells by targeting the endoplasmic reticulum stress/SKP2/β-TrCP1/CDK4 axis.

Abstract
Background
Human epidermal growth factor receptor 2 (HER2)-low breast cancer has emerged as a new subtype of tumor, for which novel antibody–drug conjugates have shown beneficial effects. Assessment of HER2 requires several immunohistochemistry tests with an additional in situ hybridization test if a case is classified as HER2 2+. Therefore, novel cost-effective methods to speed up the HER2 assessment are highly desirable.

Methods
We used a self-supervised attention-based weakly supervised method to predict HER2-low directly from 1437 histopathological images from 1351 breast cancer patients. We built six distinct models to explore the ability of classifiers to distinguish between the HER2-negative, HER2-low, and HER2-high classes in different scenarios. The attention-based model was used to comprehend the decision-making process aimed at relevant tissue regions.

Results
Our results indicate that the effectiveness of classification models hinges on the consistency and dependability of assay-based tests for HER2, as the outcomes from these tests are utilized as the baseline truth for training our models. Through the use of explainable AI, we reveal histologic patterns associated with the HER2 subtypes.

Conclusion
Our findings offer a demonstration of how deep learning technologies can be applied to identify HER2 subgroup statuses, potentially enriching the toolkit available for clinical decision-making in oncology.

Abstract
Background
Tuberculosis (TB) is a major infectious disease with significant public health implications. Its widespread transmission, prolonged treatment duration, notable side effects, and high mortality rate pose severe challenges. This study examines the epidemiological characteristics of TB globally and across major regions, providing a scientific basis for enhancing TB prevention and control measures worldwide.

Methods
The ecological study used data from the Global Burden of Disease (GBD) Study 2021. It assessed new incidence cases, deaths, disability-adjusted life years (DALYs), and trends in age-standardized incidence rates (ASIRs), mortality rates (ASMRs), and DALY rates for drug-susceptible tuberculosis (DS-TB), multidrug-resistant tuberculosis (MDR-TB), and extensively drug-resistant tuberculosis (XDR-TB) from 1990 to 2021. A Bayesian age-period-cohort model was applied to project ASIR and ASMR.

Results
In 2021, the global ASIR for all HIV-negative TB was 103.00 per 100,000 population [95% uncertainty interval (UI): 92.21, 114.91 per 100,000 population], declining by 0.40% (95% UI: − 0.43, − 0.38%) compared to 1990. The global ASMR was 13.96 per 100,000 population (95% UI: 12.61, 15.72 per 100,000 population), with a decline of 0.44% (95% UI: − 0.61, − 0.23%) since 1990. The global age-standardized DALY rate for HIV-negative TB was 580.26 per 100,000 population (95% UI: 522.37, 649.82 per 100,000 population), showing a decrease of 0.65% (95% UI: − 0.69, − 0.57 per 100,000 population) from 1990. The global ASIR of MDR-TB has not decreased since 2015, instead, it has shown a slow upward trend in recent years. The ASIR of XDR-TB has exhibited significant increase in the past 30 years. The projections indicate MDR-TB and XDR-TB are expected to see significant increases in both ASIR and ASMR from 2022 to 2035, highlighting the growing challenge of drug-resistant TB.

Conclusions
This study found that the ASIR of MDR-TB and XDR-TB has shown an upward trend in recent years. To reduce the TB burden, it is essential to enhance health infrastructure and increase funding in low-SDI regions. Developing highly efficient, accurate, and convenient diagnostic reagents, along with more effective therapeutic drugs, and improving public health education and community engagement, are crucial for curbing TB transmission.

E-learning-oriented assessment and collaborative reflection for situated learning in language teacher education
Authors: Arefian Mohammad Hossein , Esfandiari Rajab 
Published: August 2024

AbstractOnline teacher education programs can be more situated by engaging student teachers in Internet-based collaborative reflection (ICR) and e-learning-oriented assessment (ELOA) via Web 2.0 technology. Thus, this study explored how the role of English-as-a-foreign-language (EFL) student teachers’ ICR practices and ELOA can enhance student teachers’ situated online teacher education. In this qualitative study, 15 Iranian EFL student teachers were chosen purposively within a transcendental phenomenology to conduct ICR on ELOA practices during situated learning in online teacher education. The results showed that implementing ICR on ELOA tended to enhance student-centered teacher education; collaborative and reflective teacher development; social, professional, cognitive, and emotional growth; and the connection of teaching, learning, and assessment within online teacher education. More specifically, ELOA practices allowed for meaningful tasks and authentic activities based on practical experience, triggered continuous feedback on EFL student teachers’ performance via technology, directed online learning and teaching, and enhanced a performance-based and learning-oriented assessment process. Pedagogical implications for the design of student teacher programs are discussed.

Abstract
Background
Large variation in the prevalence of ankylosis and replacement resorption (ARR) is reported in the literature and most studies have relatively small patient numbers. The present retrospective study aimed to provide an overview on prevalence, location of, and associated risk factors with ARR based on a large sample of computed tomography (CT) / cone beam computed tomography (CBCT) scans of impacted teeth. The results should allow clinicians to better estimate the risk of ARR at impacted teeth.

Methods
The CT/CBCT scans of 5764 patients of a single center in Central Europe were screened with predefined eligibility criteria. The following parameters were recorded for the finally included population: gender, age, tooth type/position, number of impacted teeth per patient, and presence/absence of ARR. For teeth with ARR the tooth location in reference to the dental arch, tooth angulation, and part of the tooth affected by ARR were additionally registered.

Results
Altogether, 4142 patients with 7170 impacted teeth were included. ARR was diagnosed at 187 impacted teeth (2.6%) of 157 patients (3.7%); 58% of these patients were female and the number of teeth with ARR per patient ranged from 1 to 10. Depending on the tooth type the prevalence ranged from 0 (upper first premolars, lower central and lateral incisors) to 41.2% (upper first molars). ARR was detected at the crown (57.2%), root (32.1%), or at both (10.7%). After correcting for confounders, the odds for ARR significantly increased with higher age; further, incisors and first/second molars had the highest odds for ARR, while wisdom teeth had the lowest. More specifically, for 20-year-old patients the risk for ARR at impacted incisors and first/second molars ranged from 7.7 to 10.8%, but it approximately tripled to 27.3–35.5% for 40-year-old patients. In addition, female patients had significantly less often ARR at the root, while with increasing age the root was significantly more often affected by ARR than the crown.

Conclusion
ARR at impacted teeth is indeed a rare event, i.e., only 2.6% of 7170 impacted teeth were ankylosed with signs of replacement resorption. On the patient level, higher age significantly increased the odds for ARR and on the tooth level, incisors and first/second molars had the highest odds for ARR, while wisdom teeth had the lowest.

Abstract
Background
Papillary thyroid carcinoma rarely undergoes anaplastic transformation. Some risk factors for anaplastic transformation of thyroid cancer are known, but such transformation is difficult to predict in practice. We report a case demonstrating elevations of neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) over time as a precursor to anaplastic transformation of thyroid carcinoma.

Case presentation
The patient was an 89 year-old woman with a history of chronic aortic dissection. She was referred to our department after her local doctor detected thyroid nodules. She had previously been found to have multinodular goiter and enlarged left cervical lymph nodes on computed tomography. Her chief complaint was cervical discomfort and hoarseness. Blood tests revealed: white blood cells (WBCs), 4900 /µL; CRP, 0.29 mg/dL; neutrophils, 64.4%; and lymphocytes, 25.4%. A 21 mm mass was identified in the upper left lobe. Left III (16 mm) and left VI (16 mm) lymph node were enlarged on ultrasonography. Fine-needle aspiration cytology diagnosed malignant papillary carcinoma. However, due to the advanced age and medical history of the patient, a non-surgical policy was implemented. The primary tumor grew to 4 cm in diameter by 9 months after diagnosis, and blood tests showed: WBC, 7700 /µL; CRP, 0.18 mg/dL; neutrophils, 65.3%; and lymphocytes, 22.3%. By 10 months after diagnosis, the tumor had increased rapidly in diameter to 8 cm, with blood tests showing: WBC, 6500 /µL; CRP, 1.01 mg/dL; neutrophils, 68.2%; and lymphocytes, 19.3%. Anaplastic transformation of papillary thyroid carcinoma was diagnosed, and the patient was placed on treatment under a policy of best supportive care. Multiple lung metastases appeared 11 months after diagnosis, and blood test results showed: WBC, 13,300 /μL; CRP, 11.28 mg/dL; neutrophils, 93.6%; and lymphocytes, 2.3%. Unfortunately, the patient died of disease progression 63 days after identification of undifferentiated metastasis.

Conclusions
Chances to see the natural history of anaplastic transformation of thyroid cancer are rare. Elevations in NLR and CRP over time may be precursors to anaplastic transformation.
A case of MERS presenting with acute motor aphasia and tetraparesis and literature review
Authors: Şahan Halime , Yabalak Ahmet 
Published: August 2024

Abstract
Background
Mild encephalopathy wıth reversible splenial lesions (MERS) are a clinical–radiological diagnosis that can be diagnosed with radiological imaging and can be accompanied by impaired consciousness, aphasia, headache, and paralysis. MERS can be divided into two different types based on radiological findings; Involvement of the splenium is seen in type 1, and involvement of the splenium and deep white matter is seen in type 2. MERS Type 2 is very rare in adults. Here, we describe a patient diagnosed with MERS Type 2 and our therapeutic intervention.

Case presentation
A 22-year-old woman presented with slurred speech, weakness in the extremities and headache that started 14 h ago. The patient had sore throat and fever of 37.6 °C for 2 days, and medical history or family history were unremarkable. Neurological examination revealed that she was conscious, cooperative, with no signs of meningeal irritation. Speech comprehension, naming, and repetition were preserved, motor examination revealed 5/5 left upper extremity strength, 4/5 right upper extremity strength, and 2/5 bilateral lower extremity strength. Diffusion-weighted magnetic resonance imaging (MRI-DWI) revealed bilateral deep white matter and splenium symmetrical diffusion restriction. Blood tests showed high C-reactive protein (CRP) and no leukocytosis. No cells were detected in the cerebrospinal fluid (CSF), protein was 151 mg/dl, glucose was within normal limits. The patient, who developed quadriparesis during follow-up, was started on pulse dose steroids. Neurological examination improved to patient’s baseline at the 12th hour of treatment. In the 72nd hour control MRI-DWI, it was seen that the lesions had regressed. Culture/Polymerase chain reaction (PCR) for bacterial/viral infection agents came back negative. After steroids were given for 5 days, patient was discharged at her baseline.

Conclusions
MERS is a rare diagnosis in adults and can be radiologically confused with acute toxic leukoencephalopathy. It can be distinguished clinically by the absence of prior infection, fever, and toxic agent exposure. Although there is no consensus in the literature regarding the treatment, the clinical picture improved rapidly after steroid in our case. Despite being rare, it should be considered in the differential diagnosis of patients with deep white matter lesions in adults.

Abstract
Background
Diabetes Self-Care Management (DSCM) is crucial for managing diabetes mellitus and improving patients’ well-being. Research on the young age group in Jordan is limited, and there is a lack of studies using an evaluation tool for understanding diabetes pharmacotherapy. This study intends to fill the information gap by examining young Jordanian patients’ knowledge and comprehension of type 1 diabetes mellitus (T1DM) and its treatment modalities, evaluating their psychological well-being, and examining the relationship between children’s psychological health and self-care.

Methods
This cross-sectional study was conducted in the Jordanian Ministry of Health hospitals in Amman from June 2021 to January 2022. A convenience sampling method was used to select Arabic-speaking diabetic patients aged 11-a8 years who provided signed consent. A sample size of 400 was estimated. A self-administered questionnaire was developed based on a literature review to assess sociodemographic characteristics and diabetes and insulin knowledge, and validated scales were used to assess self-management (SMOD-A) and psychological well-being (ChilD-S).

Results
Analysis of the questionnaire responses revealed varying levels of knowledge among the participants. Approximately half of the children (49.0%) demonstrated a lack of knowledge of diabetes pharmacotherapy. Psychological well-being indicators indicated moderate levels of happiness and feeling fine. The analysis of self-management indicators highlighted areas for improvement. Positive weak but significant correlations were found between children’s knowledge about diabetes (r = 0.255, p < 0.01), diabetes pharmacotherapy knowledge (r = 0.125, p < 0.05), psychological well-being (r = 0.112, p < 0.05), and their diabetic self-management scores. A multivariate regression analysis identified predictors of self-management, including the child’s school year (p = 0.035), ability to express feelings (p = 0.039), recent HbA1c levels (p = 0.028), and diabetes knowledge score (p < 0.001).

Conclusion
Participants exhibited varying levels of knowledge about diabetes pharmacotherapy and self-management. Knowledge about diabetes was identified as a predictor for effective self-management. Moreover, glycemic control and diabetes mellitus awareness majorly impact overall self-management behaviors. Tailored education programs are necessary to fill knowledge gaps and enhance diabetes management among children.
Extraction of arsenic from fine dust of copper smelters by reduction roasting with natural gas

Published: August 2024

AbstractOne of the current trends in the complex processing of fine dust from copper smelters is their direct leaching with sulfuric acid. As practical results show, high reliable technological parameters are not achieved due to the high content of arsenic in dust. During sulfuric acid leaching of dust, arsenic is distributed between the lead cake and the solution at a ratio of 40 and 60%, respectively. The redistribution of arsenic between leaching products significantly reduces the technological performance and leads to the accumulation of arsenic in the technological scheme. The paper presents the results of comprehensive studies of the elemental and phase composition of fine dust from one of the copper smelters in Kazakhstan. In the initial dust, along with the main phases presented in the form of lead and zinc sulfate, the following typical components were found: oxides of copper, lead, zinc and copper and zinc ferrites. Arsenic is found in two forms—As(III) and As(V). The laboratory installation and technique for conducting reduction roasting of dust with natural gas are presented. The influence of roasting duration, temperature and natural gas consumption on the extraction of arsenic from dust was studied. It has been established that almost complete, up to 99%, extraction of arsenic from dust is achieved with optimal technological roasting parameters: duration τ = 40 min.; natural gas consumption is 1.5 times higher than the stoichiometrically required amount for the reduction of As2O5, and temperature 500 °C.
