Effect of exercise on plasma insulin levels in individuals with type 1 diabetes: A systematic review and meta-analysis.

Current evidence of the impact of acute exercise on insulin levels in individuals with type 1 diabetes remains controversial. Therefore, we conducted a systematic review and meta-analysis to explore exercise-induced changes in insulin levels. We conducted a systematic review (until 05 November 2023) and meta-analysis exploring the effect of exercise on insulin concentration in individuals with type 1 diabetes. We included randomised cross-over studies for rapid-acting insulin and pre- and post-studies for long-acting insulin in individuals with type 1 diabetes performing any type of acute exercise and had a control condition. The exercise-induced change in insulin levels was the outcome of interest. When possible, the mean differences (MDs) in insulin levels were pooled using the DerSimonian and Laird random effect method. Risk of bias was assessed for each included study. Seventeen trials, encompassing 186 participants with type 1 diabetes, were included in the systematic review. Twelve out of 17 studies included participants on rapid-acting insulin regimens and used a cross-over design, whereas five out of 17 single-arm studies included participants on (ultra)long-acting insulin. Seven out of 12 studies on rapid-acting insulins and all the single-arm studies were at high risk of bias. Results suggest a statistically significant, small-to-moderate increase of rapid-acting insulin after 30 min of exercise (MD of 18.44 [95% CI 0.02; 36.86; I2 0%] pmol/L); meanwhile, findings on (ultra)long-acting insulin were inconclusive. A small-to-moderate increase of insulin levels in studies including rapid-acting insulin was found after a bout of physical exercise in individuals with type 1 diabetes. However, current gaps in high-quality evidence challenge our understanding of insulin kinetics around exercise.

Contamination of Disposable Distal Cap Duodenoscopes and Detachable Elevator Duodenoscopes After Reprocessing: A Randomized Trial.

To reduce bacterial contamination after reprocessing, various new designs of duodenoscopes have been developed to better expose the elevator complex for cleaning. We compared the rates of bacterial contamination and organic residue in disposable distal cap duodenoscopes and detachable elevator duodenoscopes after manual cleaning and high-level disinfection (HLD), as well as their cost-effectiveness. A total of 162 duodenoscopes were randomly assigned to either Group A (disposable distal caps; n = 81) or Group B (detachable elevator; n = 81). A total of 324 samples from the elevator were collected for culture following manual cleaning (n = 81 in each group) and HLD (n = 81 in each group), followed by the adenosine triphosphate (ATP) testing for organic residue. After manual cleaning, there was no difference in bacterial contamination rates (8.6% vs. 8.6%; p = 1.00) and mean ATP levels (164.6 ± 257.5 vs. 158.1 ± 286.1 RLUs; p = 0.88) between Groups A and B. After HLD, no bacterial contamination was observed in either group and the mean ATP levels were very low with no significant difference between the two groups (30.1 ± 45.3 vs. 37.5 ± 51.9 RLUs; p = 0.68). The expense in reprocessing (excluding the scope cost) for Group A was lower (2099 USD) than Group B (3854 USD) in providing comparable scope cleanliness. After manual cleaning, the bacterial contamination rate and organic residue levels in detachable elevator duodenoscopes and disposable distal caps duodenoscopes were comparable. No bacterial contamination was detected in either type of duodenoscope after reprocessing. Apart from the initial differences in scope cost, the disposable distal cap duodenoscope had lower cost on disposable items to have comparable disinfection result.

Are solidarity and identification as people of color distinct? Validating new measures across Asian, Black, Latino, and Multiracial Americans

Abstract Mounting U.S. research suggests many non-White individuals feel solidarity with, and identify as, people of color (PoC). Yet measurement limitations prevent scholars from testing whether these constructs are empirically different. We explain why these concepts diverge and evaluate our claims with an expanded battery of measures across U.S. Asian, Black, Latino, and Multiracial adults (N = 3402). Using multi-group confirmatory factor analysis, we show these items capture related but distinct concepts among PoC (configural invariance). We then establish that these items uniformly measure each construct across PoC groups (metric invariance), with mean level differences validly reflecting actual heterogeneity between groups, rather than measurement artifacts (scalar invariance). Finally, consistent with our conceptualization, we show that solidarity among PoC mediates the association between PoC identification and support for policies that implicate various communities of color. We end with practical advice for using these items in surveys of racially diverse populations.

Application of mitoxantrone hydrochloride in lymph node imaging during radical thyroidectomy

Objective: To investigate the clinical application value of the new tracer mitoxantrone hydrochloride in imaging of cervical lymph nodes and identifying of parathyroid, recurrent laryngeal nerve during thyroid cancer radical surgery. Methods: A prospective controlled study was conducted between January 2022 and April 2024 at Tianjin First Central Hospital, recruiting 180 patients with thyroid cancer, including 54 males and 126 females, aged from 26 to 69 years. The patients were randomly divided into three groups: the mitoxantrone hydrochloride lymph node tracing group (MHI group), the nanocarbon lymph node tracing group (nanocarbon group), and the control group without lymph node tracers, with 60 cases in each group. All patients underwent total thyroid resection and regional lymph node dissection. The number of detected lymph nodes and positive metastatic lymph nodes and surgical field clarity scores and the identification rate of parathyroid glands and the instances of inadvertent excision were compared between the groups. Serum calcium and parathyroid hormone (PTH) levels at different perioperative time points and treatment-related complications were analyzed. One-way ANOVA, chi-square test and two independent sample non-parametric tests, were employed for statistical analyses. Results: The mean operation time, neck drainage volume and hospital stay in the MHI group and the nanocarbon group were respectively significantly lower than those in the control group (P<0.05). The mean staining intensity score, tracer success rate and surgical field clarity score in MHI group were respectively significantly higher than those in nanocarbon group (P<0.05). The mean numbers of dissected lymph nodes positive metastatic nodes and identification rates of parathyroid glands in MHI group were respectively significantly higher than those in both the nanocarbon and control groups (P<0.05). The rates of inadvertent parathyroid excision in both MHI group and nanocarbon group were significantly lower than those in control group (P<0.05). On postoperative day 1 and day 5, mean serum calcium and PTH levels in MHI group were respectively significantly higher than those in nanocarbon group and control groups. However, on postoperative day 1, there was no difference in mean serum calcium levels between the nanocarbon group and the control group (P>0.05), though PTH level in the nanocarbon group was higher than that in the control group. By postoperative day 5, both serum calcium and PTH levels were higher in the nanocarbon group compared to the control group (P<0.05). On postoperative days 30, there were no differences in serum calcium and PTH levels between the MHI group and the nanocarbon group (P>0.05). The risks of facial numbness, hand and foot tetany and choking during drinking were lower in both the MHI and nanocarbon groups compared to the control group (P<0.05). Conclusion: MHI demonstrates advantages in rapid targeted delivery and clear staining of the surgical field during regional lymph node dissection in radical thyroidectomy for thyroid cancer, effectively reducing the risk of collateral damage to the recurrent laryngeal nerve and parathyroid glands.

Sibling and best friend conflict resolution strategies among Mexican-origin youth

Sibling relationships evolve into a more egalitarian relationship dynamic resembling friendships during adolescence, potentially facilitating the transfer of interpersonal skills across relationships. This study investigates cross-relationship associations in conflict resolution strategies with siblings and friends. Research on family-peer linkages, largely focused on White populations, often overlook the role of siblings in other ethnoracial contexts. Drawing on social learning theory, we examined mean-level differences on conflict resolution strategy use with siblings versus friends and how conflict resolution strategies with siblings were related to those with friends. Participants were older ( M = 15.48; SD = 1.57) and younger siblings ( M = 12.55; SD = .60) in 246 Mexican-origin families. Adolescents reported on their use of solution-oriented, nonconfrontational, and controlling strategies with one another and their best friends, which reflect varying considerations for oneself, others, and their relationship. Multilevel ANOVAs suggest that adolescents typically use more adaptive strategies with friends than with siblings. Actor-Partner Interdependence Models revealed significant positive associations between actor-reported conflict resolution strategies with siblings and friends, even when accounting for relationship intimacy and conflict, expressive personality characteristics, and familism values, suggesting congruence across relationships. Cross-strategy analyses indicated that controlling strategies with siblings were correlated with all strategies with friends, while nonconfrontational strategies with siblings negatively related to solution-oriented strategies with friends. These findings highlight how sibling and friend experiences shape adolescents’ interpersonal skills and suggest avenues for future research on the enduring impact on social development.

Procalcitonin as an Early Marker of Colorectal Anastomotic Leakage in Postoperative Colorectal Cancer Patients: A Systematic Review and Meta-Analysis.

Background The timely identification of colorectal anastomotic leakage (CAL)is still a significant challenge, and identifying reliable markers is essential to minimize patient morbidity and mortality. While procalcitonin (PCT) has shown promise as a biomarker for CAL, its effectiveness must be specifically evaluated in colorectal cancer patients. This systematic review and meta-analysis sought to assess the mean differences in PCT levels between individuals with and without CAL who underwent colorectal surgery for colorectal cancer. Methodology A comprehensive search of the "PubMed,""Scopus," and "Web of Science" databases was carried out, covering studies published through April 2024. The objective was to identify studies examining PCT levels in colorectal cancer patients who underwent colorectal surgery, with a particular focus on the occurrence of CAL. Data on the meanof PCT levels in CAL and non-CAL patients were extracted from the selected studies. The mean differences in PCT levels were subsequently analyzed for each postoperative day (POD). Results Seventeen articles were selected for inclusion in this systematic review. The statistical analysis included five eligible articles that assessed PCT levels in groups exclusively involving patients with colorectal cancer. The findings showed no significant increase in PCT levels in CAL patients compared to non-CAL patients on any POD when a leave-one-out sensitivity analysis was performed to validate the results. Conclusions To date, PCT levels should not be regarded as early indicators of CAL after colorectal surgery in patients with colorectal cancer. Additional research is necessary to evaluate if PCT could be a dependable marker for CAL in this particular setting.

Unlocking vitiligo’s metal code: an analytical cross-sectional study of serum levels of trace elements in vitiligo patients

Background: Vitiligo is an acquired depigmenting skin disorder often associated with social stigma and having a significant psychological impact on patients. The study aimed to determine the correlation between serum levels of copper (Cu), zinc (Zn), selenium (Se), lead (Pb), mercury (Hg), cadmium (Cd), and Cu/Pb, Cu/Hg, Cu/Cd, Se/Hg, Se/Pb, Se/Cd, Zn/Hg, Zn/Pb, and Zn/Cd ratios in vitiligo patients. Materials and methods: In this analytical cross-sectional study, we enrolled 110 vitiligo patients as cases and 110 normal adults as controls. VIDA (Vitiligo Disease Activity Score) and VASI (Vitiligo Area Severity Index) were used to assess the activity and severity of vitiligo in patients. Venous blood samples of all study participants (aged &gt;12 years) were examined for serum levels of Zn, Cu, Se, Pb, Hg, and Cd using inductively coupled plasma mass spectrometry. SPSS.21 version software was used for the analysis of the data. Results: We noted a statistically significant (p-value &lt; 0.05, student’s t-test) difference in mean serum levels of Cu, Zn, and Se (microgram/liter) between cases and controls, denoted as 1370.67 ± 484.36 versus 2887.30 ± 3744.15, 1324.50 ± 555.02 versus 1603.81 ± 551.03, 248.95 ± 120.06 versus 287.15 ± 117.37, respectively. A significantly low serum level of Se was observed in female vitiligo patients, unlike controls. Vegetarian patients had low levels of Pb (p-value &lt;0.05) in comparison to non-vegetarian patients. Significantly low Zn/Hg and Cu/Hg ratios were observed in cases compared to controls. Limitations: Our study was limited by a small sample size. Being an observational study done from a single center, chances of inclusion of patients from a limited geographical area cannot be ruled out. Conclusion: Low levels of Zn, Cu, and Se could play a crucial role in the etiopathogenesis of vitiligo, which can vary based on the gender and diet pattern of the patient.

Age and gender differences in the value development of Dutch adults in 11 years of longitudinal data

Value development over the life-span is rarely studied due to theory and data limitations. We use the LISS data, a Dutch longitudinal dataset, to study value change in adults aged 25–70 over 11 years from 2008 to 2019 (N=10,860), using the neo- socioanalyitcal model (NSM) as a theoretical framework. We find few cohort differences, differences between age groups and non-linear value change within individuals that continues until late adulthood. Gender differences in mean-levels are stable except in universalism and self-direction, while gender differences in rates of change are observed. We conclude that the NSM provides a fruitful framework to interpret value change as a maturation process toward becoming functioning members of society along gendered and age-graded normative stages.

Interdependent stigma of seeking mental health services: Examining a new scale across eight countries/regions.

Although the presence of mental health stigma associated with seeking help has been demonstrated in many parts of the world, this work has largely been from an independent perspective (i.e., "I will be perceived as crazy") rather than from an interdependent perspective (i.e., "My family will be viewed negatively"). Interdependent stigma of seeking help (i.e., the extent to which people believe their family would be devalued and shamed if they seek psychological help) may be an important type of stigma that has not been assessed. Based on self-construal theory, the present study sought to develop and evaluate the psychometric properties of an Interdependent Stigma of Seeking Help (ISSH) scale in eight different countries and regions (i.e., Australia, Brazil, Germany, Hong Kong, Taiwan, Türkiye, the UAE, the United States). Findings suggest that the psychometric properties of the eight-item ISSH are adequate for research purposes (a unidimensional scale with full invariance and internal consistency estimates from .84 to .94). The ISSH was moderately related to other measures of stigma and psychological distress. Some differences in the relationship with specific outcomes by country and region were found, and there were notable country differences in the latent mean levels of ISSH, with Hong Kong and Taiwan having the highest means, and Australia, the United States, and Brazil having the lowest levels. Results suggest that the ISSH could be used to help clarify the complex relationships between stigma and other variables of interest and might be useful in developing culturally relevant interventions.

Understanding the relations between achievement goals and self-regulated learning: a multiple goal perspective

The primary objective was to investigate the relations between college students’ achievement goals and their engagement in self-regulated learning using a person-centered approach. College students (N = 364) completed surveys that assessed mindset, self-efficacy, anxiety, achievement goals, and self-regulated learning. Latent profile analyses identified three types of achievement goal profiles: high all, high approach, and low performance. Results showed that self-efficacy and anxiety were significantly associated with the achievement goal profiles. Students who reported high levels of self-efficacy but low levels of anxiety were more likely to endorse the high approach profile. In addition, we found significant mean-level differences across the achievement goal profiles for students’ reported engagement in self-regulated learning concurrently (time management, procrastination) and later in the semester (motivational regulation, environment management). Students in the high approach profile demonstrated the most adaptive pattern of self-regulated learning. Overall, findings provide support for a multiple goal perspective that endorsing both mastery-approach and performance-approach goals can be beneficial.

Serum calcium as a candidate marker in detecting stunting in toddler

&lt;p&gt;&lt;strong&gt;&lt;em&gt;Background: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;Monitoring the nutritional status of toddlers is a very important thing to do. Calcium is one of the blood parameters that can be assessed, because calcium deficiency will affect the child's linear growth. So far, monitoring of nutritional status is only based on anthropometry and is not followed by assessment of blood parameters. &lt;/em&gt;&lt;strong&gt;&lt;em&gt;Objectives:&lt;/em&gt;&lt;/strong&gt;&lt;strong&gt;&lt;em&gt; &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;This study aims to measure serum calcium levels as a candidate marker in detecting stunting in toddlers. &lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Method:&lt;/em&gt;&lt;/strong&gt;&lt;em&gt; The design of this research is cross sectional with 62 samples of toddlers aged 2-5 years. Data on sample characteristics was obtained through a questionnaire, as for serum calcium levels measurement, venous blood samples were taken and measured with the colorimetric method. The incidence of stunting is obtained based on TB/U measurements and Z-score was calculated using Anthro 1.02 software. Data were then analyzed univariately (frequency distribution) and bivariately (&lt;/em&gt;&lt;em&gt;independent t-test and &lt;/em&gt;&lt;em&gt;chi-square) using SPSS version 22. &lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Results:&lt;/em&gt;&lt;/strong&gt;&lt;em&gt; Based on anthropometric measurements, it was found that 21 (33.9%) toddlers had stunting, 28 (45.1%) toddlers had low Serum calcium levels and the majority of toddlers (54.9%) had normal serum calcium levels. There was no significant difference (p=0.989) in mean serum calcium levels between stunting and non-stunting toddlers (1.961 ± 0.223 µq/dL vs 1.960 ± 0.175 µq/dL). Bivariate results also showed that there was no significant relationship (p=0.414) between serum calcium levels and the incidence of stunting. &lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Conclusion:&lt;/em&gt;&lt;/strong&gt;&lt;em&gt; Measuring serum calcium levels cannot be used as a candidate marker for detecting stunting in toddlers. Further research is needed with a larger number of samples and measurements of various parameters related to calcium balance.&lt;/em&gt;&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;

Effects of maternal subclinical hypothyroidism on neurodevelopment of offspring- an animal-based study

Background and Objective: Maternal subclinical hypothyroidism (SCH) during pregnancy is associated with adverse maternal and neonatal outcomes, including cognitive and neuropsychiatric effects. This study aimed to assess the impact of maternal SCH on young rats, examining behavioral and gross brain structure changes, and evaluating reversibility after levothyroxine treatment. Methods: This experimental animal study was conducted at the Aga Khan University for a duration of 10 months. The study was approved by the Ethical committee for Animal Care and Use. Fourteen female Sprague Dawley rats were grouped into Treated (induced with SCH, treated with levothyroxine), Untreated (induced with SCH, no treatment), and Control (administered saline). Pups' body weight was monitored, and histological procedures were conducted at postnatal days 7, 14, and 21. Behavioral tests (elevated plus maze, forced swim, and tail suspension) assessed anxiety and depression. The data was analysed using SPSS (version 25.0). The mean, median, and standard deviation were calculated for each quantitative parameter. A one-way ANOVA was performed to identify any variation in mean thyroid levels between groups, and an independent sample t-test was utilized to confirm mean differences in anxiety levels. Results: On postnatal day 7, untreated pups showed lower body weight compared to treated and control groups. This trend continued on days 14 and 21. By day 21, an elevated plus maze (EPM) test indicated anxiety-like behaviour in untreated pups, while they also exhibited more signs of depression in tests like the forced swim test (FST) and tail suspension test (TST). Brain structure, including the prefrontal cortex, remained intact in offspring affected by maternal thyroid dysfunction, with no significant changes observed in brain morphology across the groups. Conclusion: Despite unchanged brain structure, untreated rat pups exhibited significant behavioral differences indicative of depression. This underscores the importance of understanding the behavioral impacts of maternal SCH even in the absence of gross anatomical alterations.

Association Between Uveal Melanoma and Allostatic Load.

Allostatic load (AL) is a measure of chronic stress that is associated with worse cancer outcomes. The purpose of this retrospective cohort study was to investigate the relationship between AL and uveal melanoma (UM) clinical features. AL score was calculated as a composite of ten biomarkers in 111 patients with UM from the University of Illinois Hospital. One point was assigned to an AL score for each biomarker based on predetermined cutoff values. Linear and logistic regression analyses evaluated the relationship between AL score and several tumor clinical characteristics. High AL score had a significant relationship with extraocular extension (p=0.015). There was also a significant difference in mean blood glucose levels between the different tumor size groups (p=0.029). Higher AL scores also had a trend of being associated with a smaller tumor size (p=0.069). AL score was significantly associated with the presence of extraocular extension for uveal melanoma, while the smallest tumor size group was associated with the highest blood glucose level. No other significant correlations were found between AL and other clinical features of UM. The relationship between AL score and extraocular extension warrants further investigation. Additional research is needed to evaluate socioeconomic factors and their effect on the relationship between chronic stress and the clinical features of UM.

Test-retest reliability of the play-or-pass version of the Iowa Gambling Task

The Iowa Gambling Task (IGT) is used to assess decision-making in clinical populations. The original IGT does not disambiguate reward and punishment learning; however, an adaptation of the task, the “play-or-pass” IGT, was developed to better distinguish between reward and punishment learning. We evaluated the test-retest reliability of measures of reward and punishment learning from the play-or-pass IGT and examined associations with self-reported measures of reward/punishment sensitivity and internalizing symptoms. Participants completed the task across two sessions, and we calculated mean-level differences and rank-order stability of behavioral measures across the two sessions using traditional scoring, involving session-wide choice proportions, and computational modeling, involving estimates of different aspects of trial-level learning. Measures using both approaches were reliable; however, computational modeling provided more insights regarding between-session changes in performance, and how performance related to self-reported measures of reward/punishment sensitivity and internalizing symptoms. Our results show promise in using the play-or-pass IGT to assess decision-making; however, further work is still necessary to validate the play-or-pass IGT.

Hypophosphatemia in Chronic Obstructive Pulmonary Disease Patients Requiring Mechanical Ventilation and Its Impact on Weaning in an Intensive Care Unit of a Tertiary Care Hospital in Eastern India.

Background Hypophosphatemia, defined as a serum phosphate level less than 2.5 mg/dL, is a frequent finding in patients with chronic obstructive pulmonary disease (COPD) and has been speculated to negatively affect weaning outcomes. This study aimed to determine the incidence of hypophosphatemia in COPD patients requiring mechanical ventilation and evaluate the predictive role of hypophosphatemia as an indicator of successful weaning from mechanical ventilation in such patients admitted to the intensive care unit (ICU) in a tertiary care hospital in eastern India. Methodology This prospective observational study included 60 adult patients aged 18 to 75 years with acute exacerbations of COPD on mechanical ventilation in the ICU who were planned to undergo a weaning trial. Serum phosphate levels were assessed at the time of admission and before each weaning attempt. Weaning outcomes at each attempt, length of ventilator and ICU stay, and mortality were recorded. Data collection was initiated after approval of the Institutional Ethics Committee. Receiver operating curve (ROC) analysis was done to identify the cut-off value of serum phosphate which predicted successful weaning. Results Of 60 participants, hypophosphatemia on admission was present in 15 (25%) patients. Despite the correction, 13 (21.7%) patients had hypophosphatemia before the first weaning attempt. Only 22 patients out of 60 were successfully weaned off from mechanical ventilation in the first trial, accounting for a success rate of 36.7%, of whom 20 were normophosphatemic (90.9%). In the second and third weaning trials, hypophosphatemia was significantly associated with weaning failure. Overall differences in mean serum phosphate levels among those who failed to wean in each weaning trial and the successful attempt were statistically significant (p < 0.001). On ROC analysis of serum phosphate level before the first weaning trial, a cut-off value of ≥3.0 mg/dL was identified to have 86.4% sensitivity, 55.3% specificity, 52.8% positive predictive value, 87.5% negative predictive value, and 66.7% diagnostic accuracy in predicting weaning success. Five patients died, accounting for a mortality rate of 8.3%. Lower mean serum phosphate levels before the first weaning trial, higher mean age, and longer ventilator and ICU days were significantly associated with mortality among our study participants (p < 0.05). Conclusions Our findings suggest that maintaining normal serum phosphate levels is critical to successfully weaning off patients with COPD from ventilator support.

Influence of career awareness on STEM career interests: examining the roles of self-efficacy, outcome expectations, and gender

BackgroundThe studies of science, technology, engineering, and mathematics (STEM) career interests have progressed substantially over the recent years. However, the influence of career awareness on STEM career interests is an area that requires further discussion. Evidently, Chinese adolescents have limited awareness and interest in STEM careers in the context of the Chinese cultural milieu, which can potentially constrain their future career trajectories. This study explored the influence of career awareness on the STEM career interests of Chinese high school students, examining the mediating roles of self-efficacy and outcome expectations for STEM courses in this relationship. Additionally, it analyzes the impact of gender on the average levels and interrelations of these variables. A sample of high school students from both eastern and western regions of China (N = 2542) was selected, and data was analyzed using a structural equation modeling approach.ResultsThe findings indicate that while STEM career awareness impacts various types of STEM career interests, minor differences exist in these effects. Specifically, the influence of STEM career awareness on analytical STEM career interests is entirely mediated by self-efficacy and outcome expectations in STEM courses. However, for life-survival and life-healthy STEM career interests, this mediation is only partial, with respective effects accounting for 39% and 45%. Notably, significant mean-level differences exist between male and female students in STEM career interests and self-efficacy in STEM courses, yet the relationships among these variables remain consistent across genders.ConclusionsThis study underscores the pivotal influence of career awareness in molding STEM career interests, shedding light on the mediating functions of self-efficacy and outcome expectations within STEM courses. Through a gender-based analysis, it offers valuable insights into the differing inclinations of male and female high school students in the STEM realm, while also revealing consistent patterns in the relationships among these variables across genders. These findings underscore the necessity for heightened efforts to bolster STEM career awareness and fortify self-efficacy and outcome expectations within STEM courses, particularly in domains characterized by notable gender disparities, aiming to foster equitable advancement within the STEM disciplines.

Educational Innovation: Teacher- and Student-Made Videos to Enhance English Proficiency at University Level

In the context of English as a foreign language (EFL) education, the efficacy of various instructional approaches has been a subject of ongoing concern. Traditional teacher-led methods have been challenged by the emergence of video-based instruction, raising questions about which approach yields the more effective learning outcomes. This study investigated the impact of student- and teacher-made video implementation versus traditional teacher-led methods on EFL class outcomes. Standardized tests were used to assess the English proficiency levels of 214 students who registered for EFL classes in a higher education institution in Cuenca, Ecuador. A quantitative methodology with quasi-experimental type and Solomon four-group design was applied to examine the effects of these different instructional approaches, comparing groups both with and without pre-tests. The students were organized into groups at random. The results were arranged into two sections, one comparing post-test scores and the other focusing on mean differences among those who experienced both pre-test and post-test assessments. Notably, statistically significant differences were observed in post-test evaluations within the groups that received pre-tests, indicating that it influenced post-test outcomes. However, the most important finding was that the intervention group had a better mean difference in English level than the control group. The findings highlight the importance of considering pre-tests when designing effective instructional strategies and suggest further investigation into the dynamics of video-based versus teacher-led instruction in EFL education.

The effectiveness of pharmacist-led educational model in adult patients with allergic rhinitis: a single-center randomized control trial protocol (AR-PRISE RCT)

BackgroundAllergic rhinitis is a chronic respiratory disorder that significantly impacts patients’ quality of life (QoL) and work performance. Pharmacists are recognized as suitable professionals to provide patient education and pharmaceutical care for managing allergic rhinitis patients. However, local clinical practice guidelines, particularly regarding pharmaceutical care in public healthcare institutions, are lacking. This study protocol outlines a randomized controlled trial (RCT) designed to evaluate the effectiveness of a pharmacist-led educational model (AR-PRISE Model) in managing allergic rhinitis in adult patients compared to standard pharmaceutical care. The AR-PRISE model delivers patient educational material and a pharmaceutical care algorithm.MethodThis is a 6-month, single-center, prospective, randomized, two-arm, and parallel-group controlled trial. The trial recruits patients attending the otorhinolaryngology clinics of a tertiary referral hospital. Participants are randomized into control or intervention groups in a 1:1 ratio using permuted block randomization. The total number of participants estimated is 154, with each group requiring 77 participants. The control group receives standard pharmaceutical care, while the intervention group receives pharmacist-led education according to the AR-PRISE model. Both groups are assessed for middle turbinate endoscopy findings, disease severity, knowledge level, symptom control, medication adherence, and QoL at baseline and the end-of-study follow-up (day 180 ± 7). Depending on feasibility, intermediate follow-ups are conducted on days 60 ± 7 and 120 ± 7, either virtually or face-to-face. During intermediate follow-ups, participants are assessed for symptom control, medication adherence, and QoL. The intention-to-treat analysis includes all participants assigned to each group. An independent T-test compares the mean difference in knowledge level between the two groups. A two-way repeated measures ANOVA analysis is employed to determine between-group differences for scores of symptom control, adherence rate, and QoL. A P-value < 0.05 is considered statistically significant.DiscussionThis study protocol will provide a framework for conducting a randomized controlled trial (RCT) to evaluate the effectiveness of pharmacist-led education intervention in managing allergic rhinitis within public healthcare settings. The parameters measured in this trial will quantify outcomes associated with improvements in symptoms and QoL. By systematically assessing these outcomes, we aim to contribute valuable insights into the role of pharmacist-led interventions in enhancing the management of allergic rhinitis in public healthcare settings.Trial registrationClinicalTrials.gov NCT06027736.

Differences in Mean Anti-Pertussis Antibody Levels in Children with Acellular Pertussis Immunization and Whole Pertussis Without Booster

Background: The incidence of pertussis is increasing every year, especially in developing countries. Low immunization coverage and decreased immunity are some of the factors causing the re-increase in pertussis cases. The protection provided by the pertussis vaccine whole and acellular pertussis given as a baby will decrease with age. This study aims to determine the difference in mean levels of anti-pertussis antibodies in children who received acellular pertussis and whole pertussis immunization without a booster. Methods: A cross-sectional study was carried out at the pediatric polyclinic of Dr. M. Djamil General Hospital Padang from December 2022 to December 2023. Research subjects were children aged 5-9 years with a history of whole pertussis immunization (DPwT) 3 times or acellular pertussis immunization (DPaT) 3 times. The research subjects were examined for anti-pertussis antibody titers using the ELISA technique. Results: Thirty-four children with a history of DPwT immunization 3 times and 34 children with a history of DPwT immunization 3 times were research subjects, with mean age 6.94±1.49 in the DPwT group and 6.88 ±1.61 in the DPaT group. The mean anti-pertussis antibody level in the DPwT group (9.54 IU/mL) was higher than the DPaT group (6.96 IU/mL) but was not statistically significant (p&gt;0.05). The average antibody results showed that the antibody levels in both groups were below the antibody titer threshold that provides protection against pertussis. The results of the analysis showed that there was a significant difference in the incidence of AEFI between the DPwT and DPaT immunization groups (p&lt;0.05). Conclusion: There was no difference in anti-pertussis antibody levels in children who received DPwT and DPaT immunization 3 times. Pertussis immunization is a required booster so that antibody levels are sufficient to provide protection against pertussis.
