Impact of clinical clerkship integrated with clinical ladder on attending physicians' teaching self-efficacy.

BACKGROUND: Self-efficacy plays an important role in enhancing the teaching capabilities of attending physicians (APs). The clinical ladder (CL) is an educational approach developed in the field of nursing education that increases difficulty in an incremental manner. However, no previous study has confirmed the effectiveness of CL in medical education. Therefore, this study aimed to examine the effect of clinical clerkship integrated with clinical ladder (CC-CL) on the self-efficacy of APs. METHODS: Sixth-year medical students participated in CC-CL for 6 months starting from April 2023, and the changes in the self-efficacy of APs were retrospectively evaluated. The students were trained by the APs concurrently, and the achievement levels of each student were shared. The primary outcome measure was the physician teaching self-efficacy questionnaire (PTSQ) score. The PTSQ scores before and after CC-CL were analyzed using the Wilcoxon matched-pair signed-rank test. RESULTS: Fifteen APs from the Department of Pediatric and Child Neurology were included in this study. No significant difference was observed in the total PTSQ scores of the APs before and after CC-CL. However, a significant increase was observed in the PTSQ score of APs who participated for at least 2 h per week over a period of more than 3 months (n = 8) after CC-CL (p = 0.022). Furthermore, APs who had received their pediatrician certification < 10 years ago (n = 8) showed a significant increase in the total PTSQ score after CC-CL (p = 0.022). CONCLUSIONS: CC-CL may play an important role in cultivating the self-efficacy of less experienced APs. Further comparative studies must be conducted in the future to validate the findings of this study.

Safety and efficacy of multiple-dose versus single-dose MIBG therapy in patients with refractory pheochromocytoma and paraganglioma: a single-center retrospective analysis.

OBJECTIVE: To investigate the incidence of adverse events (AEs) following single and multiple administrations of I-131 metaiodobenzylguanidine (MIBG) therapy for inoperable pheochromocytomas and paragangliomas (PPGLs). METHODS: A single-center retrospective study was conducted on patients with inoperable PPGLs who underwent I-131 MIBG therapy between January 2000 and December 2020. A total of 28 patients with available electronic medical records were included. The treatment consisted of a single intravenous administration of 150 mCi (5.55 GBq) of I-131 MIBG. We evaluated the first MIBG treatment and repeated MIBG treatments performed within 200 days of the previous treatment. AEs for each treatment were evaluated using CTCAE version 4.0, and the statistical analysis was conducted at a significance level of p < 0.05. Objective response based on RECIST 1.1 criteria and biochemical response based on urinary catecholamines were assessed. RESULTS: The study included a total of 63 administrations, consisting of 28 single administrations (SAs), including the first administration for all 28 cases, and 35 multiple administrations (MAs), which included the second or later administrations. Hematological AEs were evaluable for 23 SAs and 29 MAs. Grade 3 or higher leukopenia occurred in 9.8% of all administrations, and Grade 3 or higher lymphopenia in 23.5%; both were manageable through observation. There were no significant differences in clinical AE Grades 1-2 (p = 0.32), hematological AE Grades 1-2 (p = 0.22), or hematological AE Grades 3-4 (p = 0.12) between MAs and SAs. Statistical analysis for each type of AE revealed significant increases in leukopenia (p < 0.01) and lymphopenia (p = 0.04). No significant difference in anemia, thrombocytopenia, or neutropenia was observed between MAs and SAs. There was no significant increase in the incidence rate of Grade 3 or higher hematological AEs for any of the parameters. The objective response rate was 0% for SAs and 36% for MAs. Biochemical response rates were 18% for SAs and 67% for MAs. CONCLUSION: In I-131 MIBG therapy for PPGLs, multiple administrations significantly increased only Grade 1 or 2 lymphopenia and leukopenia compared to single administration.

Effects of Virtual Reality Therapy Combined With Conventional Rehabilitation on Pain, Kinematic Function, and Disability in Patients With Chronic Neck Pain: Randomized Controlled Trial.

BACKGROUND: Neck pain is a common condition that leads to neck motor dysfunction and subsequent disability, with a significant global health care burden. As a newly emerging tool, virtual reality (VR) technology has been employed to address pain and reduce disability among patients with neck pain. However, there is still a lack of high-quality studies evaluating the efficacy of VR therapy combined with conventional rehabilitation for patients with chronic neck pain, particularly in terms of kinematic function. OBJECTIVE: This study aims to investigate the effect of VR therapy combined with conventional rehabilitation on pain, kinematic function, and disability in patients with chronic neck pain. METHODS: We conducted an assessor-blinded, allocation-concealed randomized controlled trial. Sixty-four participants experiencing chronic neck pain were randomly allocated into the experimental group that underwent VR rehabilitation plus conventional rehabilitation or the control group receiving the same amount of conventional rehabilitation alone for 10 sessions over 4 weeks. Pain intensity, disability, kinematic function (cervical range of motion, proprioception, and mean and peak velocity), degree of satisfaction, and relief of symptoms were evaluated at 3 timepoints (baseline, postintervention, and at 3 months follow-up). A 2*3 mixed repeated measures analysis of variance was utilized for analyzing the difference across indicators, with a significant difference level of .05. RESULTS: Both groups demonstrated significant improvements in pain, disability, and kinematic functions (P<.05) at postintervention and at 3-month follow-up. The experimental group showed superior therapeutic outcomes compared to the control group in pain reduction (mean difference from the baseline: 5.50 vs 1.81 at posttreatment; 5.21 vs 1.91 at the 3-month follow-up, respectively; P<.001), disability improvement (mean difference from baseline: 3.04 vs 0.50 at posttreatment; 3.20 vs 0.85 at the 3-month follow-up, respectively; P<.001), and enhanced kinematic functions (P<.05). Moreover, participants in the experimental group reported better satisfaction and relief of symptoms than the control group (P<.05), with better initiative for exercising during the follow-up period. However, there was no between-group difference of improvement in proprioception. No adverse events were reported or observed in our research. CONCLUSIONS: The findings of our study support the efficacy of combining VR therapy with conventional rehabilitation in alleviating pain, enhancing kinematic function, and reducing disability of patients with chronic neck pain. Future research should focus on refining the therapeutic protocols and dosages for VR therapy as well as on optimizing its application in clinical settings for improved convenience and effectiveness.

Upper-level inter-disciplinary microbiology CUREs increase student's scientific self-efficacy, scientific identity, and self-assessed skills.

Course-based undergraduate research experiences (CUREs) provide opportunities for undergraduate students to engage in authentic research and generally increase the participation rate of students in research. Students' participation in research has a positive impact on their science identity and self-efficacy, both of which can predict integration of students in Science, Technology, Engineering, and Math (STEM), especially for underrepresented students. The main goal of this study was to investigate instructor-initiated CUREs implemented as upper-level elective courses in the Biomedical Sciences major. We hypothesized that these CUREs would (i) have a positive impact on students' scientific identity and self-efficacy and (ii) result in gains in students' self-assessed skills in laboratory science, research, and science communication. We used Likert-type surveys developed by Estrada et al. (14) under the Tripartite Integration Model of Social Influence to measure scientific identity, self-efficacy, and scientific value orientation. When data from all CUREs were combined, our results indicate that students' self-efficacy and science identity significantly increased after completion. Students' self-assessment of research and lab-related skills was significantly higher after completion of the CUREs. We also observed that prior to participation in the CUREs, students' self-assessment of molecular and bioinformatic skills was low, when compared with microbiological skills. This may indicate strengths and gaps in our curriculum that could be explored further.

In vitro evaluation of the tooth bleaching efficacy and safety of high-concentration hydrogen peroxide with cold atmospheric plasma.

BACKGROUND: Using hydrogen peroxide (HP) for tooth bleaching may induce various side effects. Cold atmospheric plasma (CAP) is a promising solution. We aimed to evaluate and compare the efficacy and safety of tooth bleaching using high-concentration HP with CAP with conventional in-office bleaching. METHODS: Fifty-one discolored extracted human teeth were assigned to three groups: Group 1 (light-emitting diode with 35% HP), Group 2 (CAP with 35% HP), and Group 3 (only CAP). Bleaching was conducted over three sessions for a total of 20 min. The bleaching effect was evaluated based on the changes in color (ΔE00 and WID) and lightness (ΔL and ΔG). Safety was assessed by examining the dark areas on the enamel and monitoring the pulp chamber temperature. The study analyzed how different bleaching methods and durations affected ΔE00 and ΔWID using repeated-measures analysis of variance (ANOVA). The Kruskal-Wallis and Mann-Whitney tests were used for ΔL and dark areas, and one-way ANOVA for ΔG after 20 min of bleaching. RESULTS: The ΔE00 and WID demonstrated an interaction based on the bleaching method and time, with Group 1 exhibiting the highest ΔE00 and WID at all treatment times (p < 0.001). ΔL* and ΔG did not differ significantly between Groups 1 and 2 (p = 0.056 and 0.062, respectively) and were lowest in Group 3 (p < 0.001). Group 1 exhibited the darkest areas and highest pulp chamber temperatures (p < 0.001). Group 1 exhibited statistically significant color changes. Group 2 demonstrated similar effects, but with enhanced safety profiles. CONCLUSIONS: Group 2, although displaying a slightly less pronounced color change compared with Group 1, achieved a color alteration readily discernible to the naked eye. This suggests that CAP with 35% HP could be an interesting area for further investigation as an alternative to traditional in-office bleaching methods.

Microcystin-LR Improves Anti-Tumor Efficacy of Oxaliplatin through Induction of M1 Macrophage Polarization.

Tumor-associated macrophages within the tumor microenvironment play an immunosuppressive role by promoting tumor growth and immune evasion. Macrophages are highly plastic and can be stimulated to adopt an anti-tumor M1 phenotype. In this study, we used microcystin-LR (MC-LR), a cyclic heptapeptide produced by cyanobacteria, to induce in vitro macrophage innate immunity and transition into the anti-tumor M1 phenotype. MC-LR was also tested in vivo in a mouse model of colorectal cancer. An intraperitoneal injection of MC-LR increased the proportion of CD86⁺ M1 macrophages and triggered the maturation of CD11c⁺ dendritic cells within tumor tissues. MC-LR combined with the chemotherapeutic drug oxaliplatin significantly inhibited tumor growth in vivo. Flow cytometry analysis revealed increased infiltration of activated cytotoxic (CD8⁺, PD-1⁺) T-cells and anti-tumor cytokines (IFNγ and Granzyme B) in the tumor tissues of the combination therapy group, suggesting that this may be the primary mechanism behind the anti-tumor effect of the combination treatment. These findings indicate that MC-LR regulates the immune stimulation of macrophage polarization and dendritic cell maturation, effectively reversing tumor immunosuppression, activating an anti-tumor immune response, and enhancing tumor therapy.

An update on the anti-Spike monoclonal antibody pipeline for SARS-CoV-2.

BACKGROUND: Anti-Spike monoclonal antibodies represent one of the most tolerable prophylaxis and therapies for COVID-19 in frail and immunocompromised patients. Unfortunately, viral evolution in Omicron has led all of them to failure. OBJECTIVES: We review here the current pipeline of anti-Spike mAb's, discussing in detail the most promising candidates. SOURCES: We scanned PubMed, ClinicalTrials.gov and manufacturers' press releases for clinical studies on anti-Spike monoclonal antibodies. CONTENT: We present state-of-art data clinical progress for AstraZeneca's AZD3152, Invivyd's VYD222, Regeneron's REGN-17092 and Aerium Therapeutics' AER-800. IMPLICATIONS: The anti-Spike monoclonal antibody clinical pipeline is currently limited to few agents (most being single antibodies) with unknown efficacy against the dominant JN.1 sublineage. The field of antibody-based therapies requires boosting by both manufacturers and institutions.

Covered Stent Treatment for Direct Carotid-Cavernous Fistulas: A Meta-analysis of Efficacy and Safety Outcomes.

BACKGROUND: Direct carotid-cavernous fistulas (dCCFs) involve the abnormal shunting of blood between the internal carotid artery and the cavernous sinus. The use of covered stents (CSs) has been reported for the treatment of complex carotid artery lesions. However, the efficacy and safety of CS treatment for dCCFs remain controversial. Thus, we performed a systematic review and meta-analysis to evaluate these efficacy and safety endpoints. METHODS: A systematic literature review was performed by comprehensively searching the Medline, Embase, and Web of Science databases to identify studies that were related to CS treatment for dCCFs. Then, a meta-analysis was conducted to pool the efficacy and safety outcomes from these studies based on perioperative and follow-up data. RESULTS: Fourteen non-comparative studies enrolling 156 patients with 160 dCCFs met the inclusion criteria. When analyzing perioperative outcomes, the technical success rate was 98.5% [95% confidence interval (CI), 0.948, 1.000], and the immediate complete occlusion rate was 90.9% (95% CI, 0.862, 0.959). Vasospasm and dissection occurred in 32.2% (95% CI, 0.238, 0.463) and 0.1% (95% CI, 0.000, 0.012) of patients, respectively. The in-stent acute thrombus formation rate was 0.1% (95% CI, 0.000; 0.013). Postoperatively, the mortality rate was 0.1% (95% CI, 0.000, 0.013). Based on available follow-up data, the final complete occlusion and parent artery stenosis rates were 99.3% (95% CI, 0.959, 1.000) and 18.6% (95% CI, 0.125, 0.277), respectively. CONCLUSIONS: CS placement can be used to safely and effectively treat dCCFs. These results provide a reference for future clinical trials.

[Two kinds of percutaneous endoscopic lumbar decompression in the treatment of single level lumbar lateral recess stenosis].

OBJECTIVE: To prospectively compare the clinical efficacy and radiographic outcomes between interlaminar percutaneous endoscopic lumbar decompression(IL-PELD) and transforaminar percutaneous endoscopic lumbar decompression(TF-PELD) in the treatment of single-segment lumbar lateral recess stenosis. METHODS: From April 2018 to July 2021, 85 patients with single-segment lumbar lateral recess stenosis underment percutaneous endoscopic lumbar decompression.There were 44 males and 41 females, aged from 49 to 81 years old with an average of (65.5±8.3) years old, duration of lumbar lateral recess stenosis ranging from 3 to 83 months with an average of (26.7±16.5) months. They were divided into IL-PELD group and TF-PELD group according to the different operation methods. There were 47 patients in the IL-PELD group, including 28 males and 19 females aged from 50 to 80 yeaes old with an average age was (66.7±9.3) years old. The disease duration ranged from 3 to 65 months with an average of (25.7±15.0) months. There were 38 patients in the TF-PELD group, including 16 males and 22 females, aged from 51 to 78 years old with an average of(64.1±7.6) years old. The disease duration ranged from 4 to 73 months with an average of (27.9±18.3) months The operation time, intraoperative blood loss, intraoperative fluoroscopy, hospitalization day and complications of the two groups were recorded. Visual analogue scale (VAS) to evaluate low back pain and lower limb pain, Oswestry disability index(ODI) to evaluate lumbar function in preoperative and postoperative period(1month, 6 months and last follow-up)were recorded. the sagittal diameter of the lateral recess of the responsible intervertebral space in preoperative and 1 week after the operation were recorded. RESULTS: The operation was successfully completed in both groups without serious complications such as vascular injury, dural sac tear and nerve injury. The operation time in IL-PED group(69.3±19.3)min was significantly longer than that in TF-PELD group(57.5±14.5)min (P<0.05). There was no significant difference in the intraoperative blood loss between the two groups (P>0.05). The number of intraoperative fluoroscopy in TF-PELD group (8.8±2.6)times was significantly higher than that in IL-PED group(4.8±1.2)times (P<0.05). The hospitalization days of the two groups were not statistically significant (P>0.05). VAS for low back and lower extremity pain and ODI were (5.1±2.2), (6.9±1.3) scores and (71.4±12.6) % in IL-PELD group, and (4.7±1.8), (6.9±1.3) scores and (68.4±13.9)% in TF-PELD group. In the IL-PELD group, the VAS of low back pain was (2.4±1.5), (1.6±0.8), (1.4±0.9) scores, and the VAS of lower extremity pain was (3.0±1.2), (1.6±0.7), (1.5±1.0) scores, ODI was (32.6±11.9) %, (17.4±6.5) %, (19.3±9.3)%;In TF-PELD group, the VAS of low back pain was (2.6±1.4), (1.5±0.6), (1.4±1.0) scores, and the VAS of lower extremity pain was (2.8±1.2), (1.6±0.6), (1.5±1.2) scores, The ODI was (32.0±11.2) %, (15.0±6.1) %, and (20.0±11.3) %. The VAS and ODI of the two groups at each time point after operation were significantly improved compared with those before operation (P<0.05), but there was no statistically significant difference between the groups (P>0.05), and there was no statistically significant difference in the interaction between different time points and groups (P>0.05). At 1 week after operation, the sagittal diameter of lateral recess in both groups was significantly increased compared with that before operation (P<0.05), but there was no significant difference between the two groups at each time point (P>0.05). According to the modified Macnab criteria, IL-PELD group was rated as excellent in 24 cases, good in 19 cases and fair in 4 cases. In TF-PELD group the results were excellent in 19 cases, good in 15 cases, fair in 3 cases and poor in 1 case. There was no significant difference between the two groups (P>0.05). CONCLUSION: IL-PELD and TF-PELD can expand the lateral recess in the treatment of single level lumbar lateral recess stenosis, and have achieved good clinical effects.

Efficacy and safety of solifenacin combined with biofeedback in children with overactive bladder.

BACKGROUND: Overactive bladder is a common chronic urological disorder in children, liable to impact normal social activities, disrupt sleep and even impair self-esteem. We aimed to evaluate the efficacy and safety of solifenacin combined with biofeedback for paediatric overactive bladder. METHOD: Forty-five children with overactive bladder were enrolled and divided into three groups: 15 patients in Group A were treated with solifenacin, 15 cases in Group B with biofeedback, and the other 15 patients in Group C with the combination of solifenacin plus biofeedback. Each group was subdivided into the non-urge incontinence (non-UI) and urge incontinence (UI) groups. The remission rates were compared among the three groups at 2, 4, 8 and 12 weeks from the beginning of treatment. The side effects of solifenacin were recorded and followed up. RESULT: After 2 weeks since initial treatment, the complete response rates were 33.3% (5/15), 20.0% (3/15), and 53.3% (8/15) in the three groups. At 4 weeks, the complete remission rates were 46.7% (7/15), 33.3% (5/15), and 60.0% (9/15) respectively. Moreover, the complete remission rates of the UI groups were higher than the non-UI groups (p < 0.05). At 8 weeks, the complete response rates were 53.3% (8/15), 40.0% (6/15), and 67.7% (10/15). At 12 weeks, the complete response rates were 67.8% (10/15), 60.0% (9/15), and 86.7% (13/15). The complete response rates were higher and urodynamic parameters were improved obviously in group C than the other two groups (p < 0.05) during the follow-ups. The median voiding frequency decreased and median functional bladder capacity increased obviously in Group C after 4 weeks (p < 0.05). Dry mouth was observed in 2 patients (4.4%). 2 patients experienced constipation (4.4%), and neither case was severe. The symptoms of these four patients had relieved by reducing the dose of solifenacin. CONCLUSION: Solifenacin combined with biofeedback had good efficacy and compliance for children experiencing overactive bladder. It took only 2 weeks to achieve the complete response rate over 50%, especially for the improvement of UI symptoms.

Prospective study to evaluate radioactive iodine of 20 mCi vs 10-15 mCi in Graves' disease.

OBJECTIVES: To assess whether increasing radioactive iodine dose can increase treatment efficacy in Graves' disease. METHODS: A prospective study was conducted, including 106 patients receiving 20 mCi (740 MBq) radioactive iodine (RAI), compared with a retrospective data, including 113 patients receiving 10-15 mCi (370-555 MBq) RAI. Remission and failure rates were evaluated at 6 months post-RAI. Statistical analysis was performed using logistic regression and Kaplan-Meier curves. RESULTS: Patients receiving 20 mCi RAI demonstrated a significantly higher remission rate compared to the 10-15 mCi group (82.1% vs 66.4%, p = 0.009). Median time to remission was shorter in the 20 mCI group (3 vs 4 months, p = 0.002). Hypothyroidism at 6 months was more prevalent in the 20 mCi group (67% vs 53%, p = 0.03). Larger thyroid size (> 60 g) was associated with treatment failure (p = 0.02). CONCLUSIONS: Higher dosage (20 mCi) RAI showed superior efficacy in achieving remission compared to lower dosages (10-15 mCi) in Graves' disease treatment.

Internet-based eHealth technology for emotional well-being among the older adults with a family cancer history: full mediation effects of health information self-efficacy and cancer fatalism.

BACKGROUND: Older adults with a family cancer history (FCH) face an increased cancer risk, which may adversely impact their emotional well-being. Internet-based eHealth technologies (IETs) provide a potential solution to this challenge. This study examines the influence of using IETs on the emotional well-being of older adults with FCH. It also delves into the mediating pathways through health information self-efficacy and cancer fatalism. METHODS: This study conducted a mediation analysis using data from the Health Information National Trends Survey (HINTS 6) collected from March 2022 to November 2022, focusing on older adults with FCH who had previously searched for cancer-related information (N = 1,280). RESULTS: In the mediation model, no positive direct associations between IETs usage and emotional well-being were found. Only health information self-efficacy and cancer fatalism were found to mediate the relationship between IETs usage and emotional well-being serially (ß = 0.007, 95% CI [0.003, 0.012]). CONCLUSIONS: The findings inform health information professionals and healthcare practitioners on enhancing the impact of IETs usage on individual health information self-efficacy, which mitigates cancer fatalism, contributing to better emotional well-being in the digital era.

The whitening efficacy of a compound formula examined using an ultraviolet-induced skin melanization model.

BACKGROUND: In Eastern culture, a fair complexion is the standard of beauty, leading to appearance-related distress among women with darker skin or facial pigmentation. Women seek whitening cosmetics to enhance their skin tone or correct their pigmentation, but their safety and effectiveness are paramount factors to consider. In this study, we evaluated the safety and whitening effects of a compound formula denoted as TEST comprising astaxanthin, nicotinamide, arbutin, and tranexamic acid. METHODS: Primary skin irritation and skin-whitening efficacy were examined. Three qualified melanization areas were treated with TEST, 7% ascorbic acid, or a blank. Skin color, the individual type angle (ITA°), and the melanin index (MI) were compared among treatment areas. RESULTS: TEST did not induce a skin response and exhibited a significantly higher ITA° than the blank, while no significant difference was observed with that of 7% ascorbic acid. Furthermore, the MI of TEST was significantly reduced posttreatment. CONCLUSIONS: TEST could be integrated into spot-fading and skin-whitening cosmeceuticals or functional cosmetics.

Ustekinumab in pediatric patients with Crohn's disease: safety, and efficacy results from a multicenter retrospective study in China.

Background: Ustekinumab (UST) is approved as an effective therapy for Crohn's disease (CD) in adults. Off-label use is increasing in the pediatric population, more data on safety and efficacy in pediatric patients with CD is urgently needed. Aims: This study aimed to evaluate the clinical efficacy and safety of UST in children and adolescents with Crohn's disease. Methods: This multicenter retrospective study carried out at three tertiary care centers, and identified children who received their first dose of UST at 18 years old or younger and followed up for a minimum of 24 weeks. Data on demographics, disease behavior, location and activity, treatment history were collected. The primary outcomes were clinical remission at weeks 24-32 and weeks 48-56 of UST therapy. Secondary outcomes were clinical response at the same time points, endoscopic remission, changes in C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), albumin and fecal calprotectin, improvement in growth parameters, and rate of adverse events. Results: Sixteen patients were included, and 11/13 (84.6%) continued to receive UST after 1 year. Our data demonstrate that the clinical remission rates were 41.7% at weeks 24∼32 with the Weighted pediatric CD activity index (wPCDAI) was lower than baseline (43.8, IQR: 31.3-51.9 vs.15, IQR: 5.6-25, p < 0.001) and 75% at weeks 48-56 with wPCDAI was lower than baseline (42.5, IQR: 23.8-50 vs. 7.5, IQR: 0-13.8, p = 0.004). Five of eleven children achieved endoscopic remission. No serious adverse events were recorded during the study period. Conclusions: UST is efficacious and safe in pediatric patients with CD. Pediatric patients could benefit from UST as either a primary or secondary biologic therapy for the induction, or maintenance of remission of CD.

A study on the effect of school culture on teachers' commitment to curriculum implementation: The mediating role of self-efficacy and job satisfaction.

Within the realm of English as a Foreign Language (EFL) instruction, there was pressure and drive to achieve success in the execution of the curriculum. Nevertheless, teachers encountered difficulties in implementing the curriculum and achieving successful outcomes. In order to achieve the desired objectives in the implementation of the EFL curriculum, it is necessary to have positive interacting variables that contribute to the overall dynamics. This study aimed to investigate the effect of school culture on English language teachers' commitment to curriculum implementation (TCCI), as well as the mediating role of external factors, self-efficacy (SE), and job satisfaction (JS) on this effect. The study sample involved 533 English language teachers from public middle schools in Algeria. A questionnaire was adopted for teacher-principal relationship (TPR), teacher-teacher relationship (TTR), teacher-student relationship (TSR), SE, JS, and TCCI. The analysis was done with the help of SPSS 26, JASP, and structural equation modeling (SEM). The results showed a significantly positive direct effect of TPR, TTR, and TSR on TCCI. Furthermore, there was a positive indirect effect of TPR, TTR, and TSR had a positive indirect effect on TCCI via SE and JS. These findings suggested a number of different courses of action for policy, research, and practice regarding teachers' commitment to curriculum implementation and the interaction between teachers, principals, and students over the next several years to raise teachers' SE and JS levels.

Relationship between resilience and self-efficacy among Iranian nurses: a cross-sectional study during the post-Corona era.

BACKGROUND: Resilience and self-efficacy play an influential role in nurses' clinical performance, which are considered resources for improving adaptability and promoting work engagement. This study aimed to determine the relationship between resilience and self-efficacy among nurses at Shahroud University of Medical Sciences hospitals during the post-Corona era. METHODS: This cross-sectional study was conducted on 280 nurses in all clinical departments. Nurses with a bachelor of science in nursing or higher degree and at least one year of full-time work experience were included in the study using a convenience sampling method. Participants completed a three-part tool, which included the demographic information form, the Connor-Davidson Resilience Scale, and the General Self-Efficacy Scale. The data were analyzed using descriptive statistics and inferential tests (multivariate linear regression using the backward method). RESULTS: In this study, nurses reported low levels of resilience (63.64 ± 15.66) and high levels of self-efficacy (63.01 ± 9.57). Among the five resilience subscales, the highest mean item score was associated with "spiritual influences" (2.80 out of 4), while the lowest mean item score was associated with "trust in one's instincts and tolerance of negative affect" (2.36 out of 4). Furthermore, the multivariate linear regression model results indicated that self-efficacy accounted for 33.6% of the variance in resilience (P < 0.001 and ß = 0.952). CONCLUSION: According to the results of the present study, it is suggested that nurses' psychological capabilities, such as self-efficacy, should be increased to improve resilience and address the stressful conditions of the work environment.

The impact of scaffolded and non-scaffolded suicidal virtual human interaction training on clinician emotional self-awareness, empathic communication, and clinical efficacy.

BACKGROUND: Clinicians working with patients at risk of suicide often experience high stress, which can result in negative emotional responses (NERs). Such negative emotional responses may lead to less empathic communication (EC) and unintentional rejection of the patient, potentially damaging the therapeutic alliance and adversely impacting suicidal outcomes. Therefore, clinicians need training to effectively manage negative emotions toward suicidal patients to improve suicidal outcomes. METHODS: This study investigated the impact of virtual human interaction (VHI) training on clinicians' self-awareness of their negative emotional responses, assessed by the Therapist Response Questionnaire Suicide Form, clinicians' verbal empathic communication assessed by the Empathic Communication and Coding System, and clinical efficacy (CE). Clinical efficacy was assessed by the likelihood of subsequent appointments, perceived helpfulness, and overall interaction satisfaction as rated by individuals with lived experience of suicide attempts. Two conditions of virtual human interactions were used: one with instructions on verbal empathic communication and reminders to report negative emotional responses during the interaction (scaffolded); and the other with no such instructions or reminders (non-scaffolded). Both conditions provided pre-interaction instructions and post-interaction feedback aimed at improving clinicians' empathic communication and management of negative emotions. Sixty-two clinicians participated in three virtual human interaction sessions under one of the two conditions. Linear mixed models were utilized to evaluate the impact on clinicians' negative emotional responses, verbal empathic communication, and clinical efficacy; and to determine changes in these outcomes over time, as moderated by the training conditions. RESULTS: Clinician participants' negative emotional responses decreased after two training sessions with virtual human interactions in both conditions. Participants in the scaffolded condition exhibited enhanced empathic communication after one training session, while two sessions were required for participants in the non-scaffolded condition. Surprisingly, after two training sessions, clinical efficacy was improved in the non-scaffolded group, while no similar improvements were observed in the scaffolded group. CONCLUSION: Lower clinical efficacy after virtual human interaction training in clinicians with higher verbal empathic communication suggests that nonverbal expressions of empathy are critical when interacting with suicidal patients. Future work should explore virtual human interaction training in both nonverbal and verbal empathic communication.

Optimizing d-mannose and glyceraldehyde concentrations as glucose preservatives without clinically affecting biochemical test results.

Objectives: The objectives were to evaluate blood additives that combined lithium heparin (LH)-salt with glyceraldehyde (GLY) or d-mannose (MAN) for preserving glucose levels in plasma samples and to simultaneously determine the compatibility of these additives with 14 other biochemical tests. Methods: Blood samples from 40 subjects, equally divided into healthy and diabetic groups, were collected using five different additives. The three most effective additives, LH/GLY, LH/MAN, and LH/GLY/MAN, were selected for ensuring the best preservation of glucose levels and compatibility with 14 biochemical tests. One-way analysis of variance was used to analyze the mean paired differences of glucose level and biochemical tests. Simultaneously, the clinical criteria from Johns Hopkins Hospital were used to guide the interpretation and set acceptable thresholds for measurements that exceeded the standards. Results: The combination of 160 mmol/L GLY, 8.4 mmol/L MAN, and LH, maintained glucose levels at approximately 93.4-93.7 % for healthy subjects and 91.3-92.8% for subjects with diabetes mellitus over 8 h. The mean paired differences of glucose levels in preservation were statistically insignificant. The biases in 14 biochemical tests for LH/GLY/MAN and LH/MAN remained within the acceptable clinical criteria during the 8 h. Conclusions: Combining 160 mmol/L GLY, 8.4 mmol/L MAN, and LH, proved more effective in maintaining glucose levels than individual additives or the conventional sodium fluoride preservative. It did not yield clinical discrepancies in the 14 biochemical tests during 8 h at room temperature.

Comparison of Efficacy of Topical Betamethasone Dipropionate and Topical Minoxidil in Patients With Alopecia Areata.

Background and objective Alopecia areata (AA) is a reiterative and nonscarring type of hair loss that can affect any hairy area of the body, particularly the scalp. It manifests as patchy or confluent hair loss with variations in demographics and ethnicity. There are numerous treatment options available, including topical and systemic steroids, topical minoxidil, dithranol, tacrolimus, psoralen and ultraviolet therapy (PUVA), contact immunotherapy, and oral immunosuppressive drugs. However, no previous contrast for efficacy is present between the topical betamethasone versus topical minoxidil alone in our population. This study aims to compare the efficacy of topical betamethasone dipropionate versus topical minoxidil in patients with AA. Methodology A nonrandomized controlled study was conducted at the Department of Dermatology, Jinnah Hospital Lahore, incorporating the data of patients between July 26, 2016, and January 26, 2017, after obtaining institutional ethical approval. One hundred patients with alopecia, either on the scalp or any other hairy part, from both genders, aged between 18 and 50 years, were included in the study. Two groups were created, and patients were assigned to these groups based on the clinician's choice. Group A patients were administered betamethasone dipropionate (0.05%) lotion twice daily on affected areas for 12 weeks. Group B patients were administered minoxidil (5%) solution twice daily on affected areas for 12 weeks. A four-week follow-up plan was followed. A five-point scale score system was used for alopecia grading. After 12 weeks, the hair regrowth score (RGS) was used to compare the efficacy of treatment between the two groups. Results A total of 100 patients with grades S1 to S3 AA of less than three months duration were enrolled. Two groups were created, with 50 patients in each group. The mean age in Group A was 29.08 ± 6.51 years, while in Group B, it was 29.38 ± 6.62 years. In Group A, there were 76% males and 24% females, while in Group B, there were 74% males and 26% females. Comparison of efficacy of topical betamethasone dipropionate versus topical minoxidil in patients with AA demonstrated a greater efficacy of 74% (Grade 3 and Grade 4 responses) in Group A, while in Group B, only 42% of patients showed efficacy. A statistically significant difference was found, with a P-value of 0.001. No serious side effects were noted. Conclusions Our study concluded that topical betamethasone dipropionate (0.05%) lotion has statistically significantly higher efficacy compared to topical minoxidil (5%) solution in patients with AA.

Different doses and courses of omalizumab for patients with chronic spontaneous urticaria: A systematic review with meta-analysis and trial sequential analysis.

Background: The stability, efficacy, and safety of omalizumab at different doses and regimens for chronic spontaneous urticaria (CSU) are yet to be studied. Objective: A systematic review (SR) with meta-analysis (MA) and trial sequential analysis (TSA) was performed to assess the efficacy and safety of omalizumab in CSU. Methods: Randomised controlled trials (RCTs) of administering omalizumab versus placebo for CSU were searched. Random-effects MAs were performed using planned subgroup analyses. TSA was performed to control for the risk of random errors and assess the stability of our MA results. Publication bias was visually assessed using a contour-enhanced funnel plot and the trim-and-fill method. The quality of RCTs was assessed using the Cochrane Risk of Bias Tool 2. Results: Twelve studies met the inclusion criteria. Omalizumab had remarkable effects on the patient percentage of the weekly urticaria activity score is zero (UAS = 0) [RR 4.64, 95% CI (3.38, 6.37)], percentage of no angioedema-burdened days [MD 3.15, 95% CI (0.10, 6.19], patient percentage of UAS ≤6 [RR 3.05, 95% CI (2.46, 3.78)], and patient percentage of the weekly itch severity score minimally important difference (ISS7 MID) [RR 1.50, 95% CI (1.36, 1.66)]. Omalizumab was well tolerated across studies [RR 0.98, 95% CI (0.90, 1.08)]. TSA confirmed the above results, except for "the percentage of no angioedema-burdened day". Conclusion: Among the different doses and courses assessed, omalizumab (300 mg, 12 weeks) can be recommended as an effective treatment for patients with CSU. However, whether omalizumab improves angioedema requires further investigation. The clinical management of angioedema accompanying CSU requires further attention.
