Background: Teacher commitment and performance are important factors contributing to student achievement and the quality of education. Therefore, it is critical to draw attention to this issue by identifying factors that influence these two variables. Methods: A survey, consisted of 34 closed-ended questions, was used. The total sample comprised 2,203 teachers, including 832 men and 1,371 women. Data analysis was performed using partial least squares (PLS) structural equation modeling (SEM). Model measurement employed indicator loading, convergent and discriminant validity, Cronbach's testing, composite reliability and average variance extracted (AVE) for internal consistency. Structural model measurement employed coefficient determination (R2), effect size (F2), variant inflation factor (VIF), predictive relevance (Q2) and path analysis measures. Results: The results of the study reveal that academic supervision has a significant positive effect on commitment (β; 0.085, t-statistics; 3.792 and p-value 0.000), academic supervision also affects teacher performance (β; 0.096, t-statistics; 4.416 and p-value 0.000), managerial competence affects teacher commitment (β; 0.195, t-statistics; 8.046 and p-value 0.000), managerial competence also affects teacher performance (β; 0.149, t-statistics; 6.561 and p-value 0.000), organizational commitment affects teacher performance (β; 0.163, t-statistics; 7.263 and p-value 0.000), teacher empowerment affects teacher commitment (β; 0.489, t-statistics; 22.601 and p-value 0.000), and teacher empowerment affects teacher performance (β; 0.489, t-statistics; 22.601 and p-value 0.000). Academic supervision affects teacher commitment mediating by teacher performance (β; 0.014, t-statistics; 3.178 and p-value of 0.001). Managerial competence affects teacher commitment with teacher performance mediation (β; 0.032, t-statistics; 5.588 and p-value 0.000), and teacher empowerment affects teacher commitment with teacher performance mediation (β; 0.080, t-statistics; 7.050 and p-value 0.000). Conclusion: Academic supervision, managerial competence, and teacher empowerment significantly positively affect teacher performance directly and through teacher performance as mediating variable. Teacher empowerment is the most significant factor influencing teacher performance and commitment.

RNA-binding protein Fused-in Sarcoma (FUS) plays an essential role in various cellular processes. Mutations in the C-terminal domain region, where the nuclear localization signal (NLS) is located, causes the redistribution of FUS from the nucleus to the cytoplasm. In neurons, neurotoxic aggregates are formed as a result, contributing to neurogenerative diseases. Well-characterized anti-FUS antibodies would enable the reproducibility of FUS research, thereby benefiting the scientific community. In this study, we characterized ten FUS commercial antibodies for Western Blot, immunoprecipitation, and immunofluorescence using a standardized experimental protocol based on comparing read-outs in knockout cell lines and isogenic parental controls. We identified many high-performing antibodies and encourage readers to use this report as a guide to select the most appropriate antibody for their specific needs.

Published: June 2023

Background: Home-based rehabilitation exercise following Total Hip Arthroplasty (THA) shows similar outcomes compared to supervised outpatient rehabilitation exercise. Little is known about patients' experiences with home-based rehabilitation, and this study aimed to investigate how patients perceived home-based rehabilitation exercise and general physical activity after THA, focusing on facilitators and barriers. Methods: Semi-structured interviews of qualitative design were conducted with 22 patients who had undergone THA and who had performed home-based rehabilitation exercise. The study took place in a regional hospital in Denmark between January 2018 and May 2019. Data were analyzed using an interpretive thematic analysis approach, with theoretical underpinning from the concept ‘conduct of everyday life’. The study is embedded within the Pragmatic Home-Based Exercise Therapy after Total Hip Arthroplasty-Silkeborg trial (PHETHAS-1). Results: The main theme, ‘wishing to return to the well-known everyday life’, and four subthemes were identified. Generally, participants found the home-based rehabilitation exercise boring but were motivated by the goal of returning to their well-known everyday life and performing their usual general physical activities, though some lacked contact to physiotherapist. Participants enrolled in the PHETHAS-1 study used the enrollment as part of their motivation for doing the exercises. Both pain and the absence of pain were identified as barriers for doing home-based rehabilitation exercise. Pain could cause insecurity about possible medical complications, while the absence of pain could lead to the rehabilitation exercise being perceived as pointless. Conclusions: The overall goal of returning to the well-known everyday life served as a facilitator for undertaking home-based rehabilitation exercise after THA along with the flexibility regarding time and place for performing exercises. Boring exercises as well as both pain and no pain were identified as barriers to the performance of home-based rehabilitation exercise. Participants were motivated towards performing general physical activities which were part of their everyday life.
Case Report: Metachronous bilateral upper tract and bladder urothelial carcinoma: a long-term follow-up
Authors: Hamid Agus Rizal Ardy Hariandy , Nasher Fakhri Zuhdian , Saraswati Meilania , Matondang Sahat , Arif Mochtar Chaidir 
Published: June 2023

Background: Upper tract urothelial carcinoma (UTUC) is a malignant disease of the urothelial cell lining the upper urinary tract from renal calyces, pelvises, and ureter down to the ureteral orifice. Urothelial carcinoma is a multifocal malignant tumor which tends to reoccur after treatment. Radical cystectomy shows that upper tract recurrence occurs in 0.75% to 6.4% of patients. The occurrence of contralateral UTUC after nephroureterectomy is rarer with a prevalence of 0.5%. Case presentation: The case of a 43-year-old male with metachronous bilateral UTUC was reported. The patient had undergone gemcitabine-cysplatine neoadjuvant chemotherapy followed by radical cystectomy and orthotopic neobladder for urothelial carcinoma of the bladder cT2N0M0. Left hydronephrosis was discovered three months after the procedure. The patient was diagnosed with left UTUC cT4N0M0 of renal pyelum after a series of examinations. A left open radical nephroureterectomy was conducted to remove the mass followed by adjuvant chemotherapy. This was followed up with routine ultrasound and magnetic resonance imaging (MRI) every three months with a “tumor-free” period of 26 months. Meanwhile, the patient was re-admitted with fever and an increase in creatinine value of 4.3. After further workups, the patient was diagnosed with UTUC cT2N0M0 of the right renal pyelum. A kidney sparring approach with laser evaporation of the tumor was conducted followed by eight cycles of Gemcitabine intracavity antegrade per nephrostomy. After the regimen was finished, an MRI evaluation was conducted to assess treatment results, and the mass had decreased. Conclusions: This report showed a rare case of urothelial cell carcinoma recurrences. From bladder urothelial carcinoma to left UTUC and then to contralateral UTUC. It is important to evaluate the upper tract to reduce the risk of recurrence.

Background: There is a scarcity of quality literature on the prevalence of frailty among community dwelling elderly in India. This study was originally planned to analyze the longitudinal trends in frailty status of community dwelling elderly in an Indian population as well to identify factors associated with frailty in the Indian context. However, the recruitment phase of this study coincided with one of the largest lockdowns in history, associated with the COVID-19 pandemic, and this gave us a unique opportunity to study the effects this pandemic enforced, as a result of the necessary restrictions, on the frailty status as well the factors affecting frailty in the elderly. Methods: A prospective observational study was designed and conducted amongst 19 community dwelling elderly of Dakshina Kannada District, in Karnataka India. Outcome variables of frailty (EFIP), physical activity (PASE), functional mobility (TUG), gait speed (10-meter walk test), nutritional status (MNA®-SF) body composition (BIA), and strength (dynamometry), were measured at baseline and on follow-up after three months. The changes occurring in these variables over the three-month period were analyzed and the change in frailty was independently correlated with changes in each of the other outcomes. Results: We couldn’t identify any statistically significant difference in frailty over a period of three months. However, there was a highly significant change in the physical activity status, lower extremity muscle strength, body composition, functional mobility, gait speed, and cognitive function in the same time period. Conclusions: Though individual determinants of frailty in community dwelling changed over a three-month period, these changes failed to produce any observable/measurable difference in frailty status.

Published: June 2023

In this paper, the effect of the active fiber’s core/cladding area
ratio on the output parameters of 1018 nm fiber lasers has been
investigated. In this regard, we conducted a comprehensive study of
two fiber lasers that utilized 25/400 and 30/250 µm
ytterbium-doped fibers (YDFs), both theoretically and experimentally.
The optimum length of YDFs required for 40 dB of amplified
spontaneous emission suppression was calculated. Theoretical studies
also identified the YDF breaking zone for lengths greater than the
optimum. The experimental results showed that selecting the proper
dimensions and coiling diameter for the active fiber significantly
increased the power and efficiency of the YDF laser. We obtained an
output power of 943 W with a 75.5% slope efficiency for the
co-pumped 30/250 µm YDFL which, to the best of our knowledge,
is the highest reported value for the 1018 nm co-pumped fiber
laser. An analysis of the experimental and theoretical results
revealed that YDFs with a core/cladding area ratio greater than 1% are
more suitable for realizing a high-power 1018 nm fiber laser.
The findings of this study are crucial for the development of
high-power 1018 nm fiber lasers with improved performance.
Deep-learning blurring correction of images obtained from NIR single-pixel imaging
Authors: Osorio Quero Carlos , Durini Daniel , Rangel-Magdaleno Jose , Martinez-Carranza Jose , Ramos-Garcia Ruben 
Published: June 2023

In challenging scenarios characterized by low-photon conditions or the presence of scattering effects caused by rain, fog, or smoke, conventional silicon-based cameras face limitations in capturing visible images. This often leads to reduced visibility and image contrast. However, using near-infrared (NIR) light within the range of 850–1550 nm offers the advantage of reduced scattering by microparticles, making it an attractive option for imaging in such conditions. Despite NIR’s advantages, NIR cameras can be prohibitively expensive. To address this issue, we propose a vision system that leverages NIR active illumination single-pixel imaging (SPI) operating at 1550 nm combined with time of flight operating at 850 nm for 2D image reconstruction, specifically targeting rainy conditions. We incorporate diffusion models into the proposed system to enhance the quality of NIR-SPI images. By simulating various conditions of background illumination and droplet size in an outdoor laboratory scenario, we assess the feasibility of utilizing NIR-SPI as a vision sensor in challenging outdoor environments.

Background
In Mexico, obesity prevalence among adults increased from 23% in 2000 to 36% in 2018, approximately. Mexico has not defined short- or long-term obesity goals, obscuring the level of effort required to achieve a relevant impact. We aimed to explore potential obesity goals for 2030 and 2040 in Mexico and to estimate the required caloric reductions to achieve them.

Methods and findings
We obtained anthropometric and demographic information on the Mexican adult population (age ≥20 years) from the Health and Nutrition Surveys conducted in 2000, 2006, 2012, 2016, and 2018 (n = 137,907). Each survey wave is cross-sectional, multistage, and representative of the Mexican population at the national, regional, and urban/rural levels. Obesity prevalence was projected for 2030 and 2040 by combining population projections of energy intake by socioeconomic status (SES) with a weight-change microsimulation model taking into account individual-level information on sex, age, physical activity, and initial body weight and height. If current trends continue, Mexico’s obesity prevalence is expected to increase from 36% (95% CI 35% to 37%) in 2018 to 45% (uncertainty interval [UI] 41% to 48%) in 2030 and to 48% (UI 41% to 55%) in 2040. Based on expert opinion, we identified 3 obesity goals scenarios: (1) plausible (38% in 2030 and 36% in 2040); (2) intermediate (33% in 2030 and 29% in 2040); and (3) ideal based on the average prevalence of Organization for Economic Co-operation and Development countries (OECD; 19%). We estimated the caloric reductions needed to achieve the goal scenarios using the microsimulation model. Obesity was projected to increase more rapidly in the low SES (around 34% in 2018 to 48% (UI 41% to 55%) in 2040), than in the middle (around 38% to 52% (UI 45% to 56%)), or high SES group (around 36% to 45% (UI 36% to 54%)). Caloric reductions of 40 (UI 13 to 60), 75 (UI 49 to 95), and 190 (UI 163 to 215) kcal/person/day would be needed to reach the plausible, intermediate, and the ideal (OECD) average scenarios for 2030, respectively. To reach the 2040 goals, caloric reductions of 74 (UI 28 to 114), 124 (UI 78 to 169), and 209 (UI 163 to 254) kcal/person/day would be required, respectively. Study limitations include assuming a constant and sedentary physical activity level, not considering cohort-specific differences that could occur in the future, and assuming the same caloric trends under no intervention and the obesity goal scenarios.

Conclusions
To reach the 3 obesity goals in 2040, caloric reductions between 74 and 209 kcal/day/person would be needed in Mexico. A package of new and stronger interventions should be added to existing efforts such as food taxes and warning labels on non-nutritious food.
Effect of vitamin energy drinks on relieving exercise-induced fatigue in muscle group by ultrasonic bioimaging data analysis
Authors: Wang Xindi , Xu Mengtao 
Published: June 2023

Objective
This work was aimed to analyze the effect of vitamin energy drink on muscle fatigue by surface electromyography (SEMG) and ultrasonic bioimaging (USBI).

Methods
20 healthy men were selected to do increasing load fatigue test. Surface electromyographic signals and ultrasonic biological images were collected based on wavelet threshold function with improved thresholds. Time domain and frequency domain characteristic integrated electromyography (IEMG), root mean square amplitude (RMS), average power frequency (MPF), and surface and deep muscle morphological changes were analyzed. Hemoglobin concentration (HB), red blood cell number (RBC), mean volume of red blood cell (MCV), blood lactic acid (BLA), malondialdehyde (MDA), and phosphocreatine kinase (CK) were measured.

Results
1) the Accuracy (94.10%), Sensitivity (94.43%), Specificity (93.75%), and Precision (94.07%) of the long and short-term memory (LSTM) specificity for muscle fatigue recognition were higher than those of other models. 2) Compared with the control group, the levels of BLA, MDA, and CK in the experimental group were decreased and HB levels were increased after exercise (P < 0.05). 3) IEMG and RMS of the experimental group were higher than those of the control group, and increased with time (P < 0.05). 4) The mean amplitude of the response signal decreased with time. Compared with the control group, the surface muscle thickness, deep muscle thickness, total muscle thickness, contrast, and homogeneity (HOM) decreased in the experimental group; while the angular second moment (ASM) and contrast increased, showing great differences (P < 0.05).

Conclusion
Surface electromyographic signal and ultrasonic biological image can be used as auxiliary monitoring techniques for muscle fatigue during exercise. Drinking vitamin energy drinks before exercise can relieve physical fatigue to a certain extent and promote the maintenance of muscle microstructure.

ObjectiveTo identify sociodemographic and educational factors associated with mental health disorders in Peruvian medical students in clinical years.MethodsCross-sectional study. We surveyed students from 24 Peruvian medical schools. We defined negative perception of educational environment as having a Dundee Ready Educational Environment Measure score below 100 points; we defined anxiety and depression as having more than 4 points on the Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9 scales, respectively. Poisson regression with robust variance was used to assess the association between negative perception of educational environment and mental health alterations.ResultsAmong the 808 participants, the prevalence of anxiety and depression symptoms was 77.6% and 67.3%, respectively. Negative perception of the educational environment was 31.6%. The factors associated with anxiety were being male (PR = 0.95, 95% CI:0.91–0.98), previous medical condition (Prevalence ratios PR = 1.10, 95% CI:1.05–1.16), previous diagnosis of coronavirus disease 2019 (PR = 0.93, 95% CI: 0.93–0.94), being from highlands (PR = 1.11, 95% CI: 1.05–1.16), studying at a national university (PR = 0.90, 95% CI: 0.88–0.92), and negative perception of the educational environment (PR = 1.04, 95% CI: 1.03–1.05), while factors associated with depression were being male (PR = 0.94, 95% CI: 0.93–0.95), previous medical condition (PR = 1.12, 95% CI: 1.08–1.17), type of university (national) (PR = 0.95, 95% CI: 0.95–0.96), and negative perception of the educational environment (PR = 1.11, 95% CI: 1.07–1.16).ConclusionWe found evidence that during the COVID-19 pandemic anxiety and depression are prevalent among Peruvian medical students. Sociodemographic factors and negative perception of educational environment were associated with the presence of these conditions.
Invasive pneumococcal disease among the elderly in the later era of paediatric pneumococcal conjugate vaccination—A longitudinal study over 10 years based on public surveillance data in the Nordics

Published: June 2023

Background
Pneumococcal conjugate vaccines (PCVs) have proven effective in preventing both non-invasive and invasive pneumococcal disease (IPD) in small children and in older age groups. However, long-term observations and country comparisons of IPD incidence in the elderly following introduction of PCVs in paediatric national immunisation programmes (NIPs) are scarce. We aimed to estimate and compare incidence of IPD in the elderly in Denmark, Finland, Norway, and Sweden over a 10-year time span. During the study period Denmark and Norway used PCV13 in their paediatric NIP, Sweden both PCV10 and PCV13 and Finland used PCV10. Uptake of pneumococcal vaccines for the elderly was low.

Method
We collected longitudinal data on confirmed IPD cases and their serotypes among elderly people (aged ≥65 years) 2010–2019 in the four countries of interest. Annual IPD incidence rates were calculated per country, by vaccine-associated serotypes (PCV10, PCV13, PCV15, PCV20 and PPV23) and for non-vaccine serotypes. A regression model was used to estimate average annual change in incidence in each country.

Results
Incidence rates of IPD in the elderly in 2019 ranged from 31.4 to 41.8 per 100,000 people across the countries. Denmark and Norway showed an annual average decline in IPD incidence (-3.3; 95% CI: -5.6 to -1.1; p<0.01) and (-3.3; 95% CI: -5.5 to -1.0; p<0.01) respectively from 2010 to 2019, whereas no change was seen for Sweden (-0.5; 95% CI: -1.9 to 0.8; p = 0.39) or Finland (0.9; 95% CI: -1.0 to 2.7; p = 0.32). IPD incidence due to emerging serotypes, e.g., serotypes 8 and 12F, has increased. Serotype 19A remained a major cause of IPD in countries with PCV10 in paediatric NIPs.

Conclusion
Despite paediatric PCV programmes, a considerable vaccine preventable IPD burden remains in the elderly. Further, choice of PCV in paediatric programs was associated with differences in serotype distribution and incidence amongst the elderly. Direct vaccination of the elderly with recently approved broad coverage PCVs holds promise for meaningful impact on disease burden with PCV20 covering a majority of IPD amongst the elderly in the four studied countries. Effectiveness of new vaccines in real-life clinical practice should be followed.
