One-year evaluation of people recovering from COVID-19 receiving allied primary healthcare: A nationwide prospective cohort study

BackgroundA Dutch nationwide prospective cohort study was initiated to investigate recovery trajectories of people recovering from coronavirus disease 2019 (COVID-19) and costs of treatment by primary care allied health professionals. ObjectivesThe study described recovery trajectories over a period of 12 months and associated baseline characteristics of participants recovering from COVID-19 who visited a primary care allied health professional. It also aimed to provide insight into the associated healthcare and societal costs. MethodsParticipants completed participant-reported standardized outcomes on participation, health-related quality of life, fatigue, physical functioning, and costs at baseline (ie, start of the treatment), 3, 6, 9 and 12 months. ResultsA total of 1451 participants (64 % women, 76 % mild/moderate severity) with a mean (SD) age of 49 (12) years were included. Linear mixed models showed significant and clinically relevant improvements over time in all outcome measures between baseline and 12 months. Between 6 and 12 months, we found significant but not clinically relevant improvements in most outcome measures. Having a worse baseline score was the only baseline factor that was consistently associated with greater improvement over time on that outcome. Total allied healthcare costs (mean €1921; SEM €48) made up about 3% of total societal costs (mean €64,584; SEM €3149) for the average participant in the cohort. ConclusionsThe health status of participants recovering from COVID-19 who visited an allied health professional improved significantly over a 12-month follow-up period, but nearly the improvement occurred between baseline and 6 months. Most participants still reported severe impairments in their daily lives, and generated substantial societal costs. These issues, combined with the fact that baseline characteristics explained little of the variance in recovery over time, underscore the importance of continued attention for the management of people recovering from COVID-19.

Advance personal planning knowledge, attitudes, and participation amongst community-dwelling older people living in regional New South Wales, Australia: A cross-sectional survey.

Advance personal planning (APP) involves planning for future periods of incapacity, including making legal decisions and documents. APP ensures that a person's values and preferences are known and respected. This study aimed to examine knowledge of APP, attitudes and confidence towards APP, and participation in APP activities among older people residing in regional and rural areas. A cross-sectional survey was conducted with people aged over 65 years residing in and around regional towns in New South Wales, Australia. Participants responded to a social media advertisement or information provided through a community organisation. Data was collected via pen and paper survey or an online survey. The survey was developed for the study and included questions about the participant and their experiences with APP. Poisson regression modelling was conducted to explore the relationship between APP participation and APP knowledge, confidence and attitudes as well as the participant characteristics associated with APP participation. Overall, 216 people completed the survey. Most participants had a will (90%) but only a third (32%) had documented an advance care directive. Knowledge of APP was low with only 2.8% of participants correctly answering all 6 knowledge questions. Participants had a positive attitude towards APP and high level of confidence that they could discuss APP issues with important people in their life. Those with increased knowledge, confidence and attitude towards APP were significantly more likely to participate in APP activities. Older age and having private health insurance were significantly associated with engaging in APP activities. Increased frailty and the presence of health conditions were not associated with increased APP participation. There is a need to increase engagement with APP particularly among those who may be considered frail or have chronic health conditions. Increasing knowledge of, confidence and attitudes towards, APP could help to increase engagement in APP activities.

Imbalances in Two-Level Hierarchical Linear Modeling of Single-Case Data: A Monte Carlo Simulation Study

Hierarchical linear modeling (HLM) is a promising approach that can be applied to explain variability in intervention effectiveness between participants in single-case experimental design (SCED) research. This approach allows the inclusion of participant characteristics as moderators to account for variability in intervention effectiveness. However, little is known about the performance of HLM for analysis with the inclusion of imbalanced intervention starting points and imbalanced moderators. Therefore, the goal of this study is to empirically evaluate the statistical properties of this model through a large-scale Monte Carlo simulation study under these scenarios. The results indicate that imbalanced intervention starting points have no impact on the statistical properties of estimating intervention effects. On the other hand, imbalanced moderators have an impact on estimating the intervention and moderator. How the conditions of imbalanced moderators influence the performance of two-level HLM depends on how the moderators are coded. Two general conclusions can be made. The model results in more favorable statistical properties when (i) a larger number of participants are included and (ii) the variability in continuous moderators is larger. Practical implications for the design and analysis of SCEDs are discussed.

Prenatal Screening of Chromosomal Anomalies Using Genome-Wide or Target Cell-Free DNA: Preferences and Satisfaction of Pregnant Women.

Background/Objectives: Cell-free DNA (cfDNA) is a non-invasive prenatal test used to screen for common trisomies (target cfDNA) that can be expanded to assess all autosomal chromosomes (genome-wide cfDNA). As cfDNA testing gains popularity, it is crucial to examine the factors influencing the decision-making process of pregnant individuals when choosing between these two approaches. Methods: In this prospective cohort study, 190 individuals undergoing cfDNA testing for aneuploidy screening, according to the current screening protocol, were allowed to make their own choice between target and genome-wide cfDNA testing. They were asked to complete a first survey at 11-13 weeks, designed to explore their characteristics, preferences, and satisfaction with the prenatal genetic counseling session, as well as a Decisional Conflict Scale. A postnatal survey was administered three months after delivery, including the Decisional Regret Scale and two open questions. Results: 84% of participants opted for genome-wide cfDNA. However, 17% found the decision challenging, and 14% felt that the results might increase anxiety. No significant differences in participant characteristics were found when comparing decisions between genome-wide and target cfDNA. However, significant differences were observed regarding ethnicity (p = <0.001), educational level (p = 0.029), previous cfDNA experience (p = 0.004), and having sufficient information when comparing termination options (p = 0.002). After delivery, only 4% would have changed their decision. Conclusions: Individuals, regardless of their characteristics, prefer genome-wide cfDNA; however, the complexity of the results necessitates enhanced genetic education for prenatal care clinicians.

Physical activity in adult users of inpatient mental health services: A scoping review.

People with severe mental illness engage in considerably less physical activity than those without. They also experience premature mortality of around 10-25 years. A large proportion of these premature deaths are attributed to modifiable behaviours, including physical activity. The inpatient environment provides an opportunity to support people to become more physically active; however, there is limited evidence on which interventions are most successful and what contextual factors affect their delivery. A scoping review was conducted to help understand the extent and type of evidence in this area and identify research gaps. We included studies of physical activity correlates and interventions in adult inpatient mental health services published in peer-reviewed journals. Reviews, meta-analyses, and papers focusing on eating disorder populations were excluded. We searched the MEDLINE, CINAHL, PsycINFO, ASSIA and Web of Science databases for relevant studies published in English. We extracted data on study design, participant characteristics, intervention and control conditions, key findings, and research recommendations. We used a descriptive analytical approach and results are presented in tables and figures. Of 27,286 unique records screened, 210 reports from 182 studies were included. Sixty-one studies reported on correlates of physical activity, and 139 studies reported on physical activity interventions. Most intervention studies used a single-group, pre-post design (40%) and included fewer than 100 participants (86%). Ninety percent of interventions delivered physical activity directly to participants, and 50% included group-based sessions. The duration, type, frequency and intensity of sessions varied. Mental health was the most commonly reported outcome (64%), whereas physical activity was rarely an outcome (13%). Overall, there is a modest but growing body of research on physical activity in adult users of inpatient mental health services. More high-quality trials are needed to advance the field, and future research should target neglected intervention types, outcomes, populations and settings.

Participation rates, characteristics, and differential effects on reading literacy of extracurricular tutoring in a German large-scale assessment

Because large-scale studies repeatedly indicated low reading literacy for many students, a need for interventions fostering reading literacy, such as extracurricular tutoring, has often been emphasized. Several reading promoting programs, suitable for extracurricular tutoring, were developed and shown to be effective in recent years. Moreover, these studies and analyses of extracurricular activities and tutoring yielded findings on learning-supporting characteristics and effects on students’ achievement of such extracurricular offers. Nevertheless, little is known to date about the implementation of extracurricular tutoring in practice in Germany, particularly about its participation rates, characteristics, and effects on students` reading literacy. Thus, the present study investigated participation rates of extracurricular tutoring in reading and in German among students in general and among various subgroups between Grades 5 and 7. Furthermore, the study examined general and subject-specific characteristics and effects of extracurricular tutoring on reading literacy. The analyses used a sample of students (N = 5113) of the National Educational Panel Study in Germany. In addition to descriptive analyses of characteristics and participation rates of extracurricular tutoring, effect sizes were calculated for comparing participation rates of subgroups of students. Furthermore, multi-group structural equation models were implemented to investigate average and differential effects of extracurricular tutoring, while controlling for initial reading literacy and other covariates. The results indicate that mainly students with low reading literacy and therefore a strong need for support participated in extracurricular tutoring, but the general participation rate was low. The descriptive outcomes showed a heterogeneous picture of tutoring offers and rare implementations of reading-promoting methods. Moreover, the results revealed no significant effects of extracurricular tutoring on students’ reading literacy overall but suggested marginal differences for students with a low initial reading literacy. For future studies, more detailed assessments of characteristics and methods of extracurricular tutoring are recommended, particularly, in large-scale investigations on specific tutoring methods for students with support needs which may lead to improved guidelines regarding promising implementations of evidence-based reading promoting programs.

Weight Loss With Once-nightly Sodium Oxybate for the Treatment of Narcolepsy: Analysis From the Phase III Randomized study Evaluating the efficacy and SafeTy of a ONce nightly formulation of sodium oxybate (REST-ON) Trial

Individuals with narcolepsy are more likely to be obese than the general population. Changes in weight-related measures with extended-release, once-nightly sodium oxybate (ON-SXB) and characteristics of participants with ≥5% weight loss were assessed in a Randomized study Evaluating the efficacy and SafeTy of a ONce nightly formulation of sodium oxybate (REST-ON) trial post hoc analysis. REST-ON (NCT02720744) was a Phase III, double-blind, placebo-controlled, multicenter, randomized clinical trial. Participants aged ≥16 years with narcolepsy type 1 (NT1) or NT2 received ON-SXB or placebo for 13 weeks (week 1, 4.5 g; weeks 2-3, 6 g; weeks 4-8, 7.5 g; and weeks 9-13, 9 g). Weight and body mass index were measured at baseline and study end. Weights were similar between groups at baseline (mean [SD]; ON-SXB, 81.2 [20.8] kg; N = 107 [NT1, n = 80; NT2, n = 27]; placebo, 82.1 [22.5] kg; N = 105 [NT1, n = 82; NT2, n = 23]). At week 13 (9 g), mean (SD) weight decreased 1.3 (3.6) kg with ON-SXB and increased 0.2 (2.6) kg with placebo; 17.8% (19/107; NT1, n = 14; NT2, n = 5) of participants receiving ON-SXB had ≥5% weight loss versus 3.8% receiving placebo (4/105; NT1, n = 3; NT2, n = 1; P = 0.001). At week 13, least squares mean (SE) body mass index change from baseline was ‒0.51 (0.13) kg/m2 with ON-SXB and 0.08 (0.13) kg/m2 with placebo (least squares mean difference [95% CI], -0.59 [-0.95 to -0.23] kg/m2; P = 0.001). Excessive daytime sleepiness improved for both groups with ON-SXB, the ≥5% weight-loss subgroup exhibited larger improvement in the Maintenance of Wakefulness Test and Epworth Sleepiness Scale versus the other subgroup (weight loss <5%, no change, or weight gain) (Maintenance of Wakefulness Test, P = 0.019; Epworth Sleepiness Scale score, P < 0.001). Narcolepsy is often associated with obesity, which may increase cardiometabolic risks. ON-SXB, an effective treatment for excessive daytime sleepiness and cataplexy, may be preferred in overweight or obese individuals to provide a more tailored treatment approach. NCT02720744.

Root canal transportation with ProTaper Next and WaveOne Gold: A systematic review

Root canal transportation is a significant concern in endodontic therapy, impacting treatment outcomes. ProTaper Next (PTN) and WaveOne Gold (WOG) are popular endodontic instrumentation systems used to shape root canals. This systematic review aimed to evaluate the literature on root canal transport with PTN and WOG. Fourteen studies were analyzed, highlighting the overall effectiveness of both systems. The PTN showed potential advantages in minimizing canal transport, while the WOG preserved the original canal shape. Operator experience and canal curvature influence performance. This review provides evidence-based insights to aid endodontic practitioners in making informed decisions for successful root canal treatments. The aim of this systematic review was to evaluate and synthesize the literature on root canal transportation with ProTaper Next (PTN) and WaveOne Gold (WOG) instrumentation systems in endodontic therapy. A comprehensive literature search was conducted using the PubMed Central, Scopus, EBSCO, Embase and Web of Science databases from 2000 to 2022. Studies that met the predefined inclusion and exclusion criteria were selected for analysis. Data on study design, participant characteristics, intervention details, comparison groups, outcomes, and results were extracted from the included studies. The methodological quality of the studies was assessed using appropriate tools, and the findings were synthesized qualitatively. A total of 14 studies were included in the systematic review. The analysis revealed that both the PTN and WOG systems demonstrated overall effectiveness in root canal preparation. PTN rotary files performed adequately with inexperienced operators and showed potential advantages in minimizing canal transportation. On the other hand, WOG files exhibited a conservative approach, preserving the original canal shape. However, variations in performance were observed depending on the instrumentation method, operator experience, and canal curvature. This systematic review provides valuable insights into the ability of the PTN and WOG to manage root canal transport. Both systems demonstrated satisfactory outcomes, with WOG often preserving the natural canal anatomy. The findings suggest that proper operator training and technique play vital roles in achieving optimal results. Clinicians should consider the unique characteristics of each system when selecting instrumentation for root canal treatments. Nonetheless, it is crucial to acknowledge the limitations of the included studies, such as variations in sample sizes and operator experience, which may impact the interpretability of the findings. Future research should address these limitations and further explore the efficacy of these instrumentation systems in various clinical settings. The evidence derived from this systematic review can aid endodontic practitioners in making evidence-based decisions for successful root canal procedures.

Assessment of practice and perceptions of healthcare professionals regarding the contribution of inappropriate pharmaceutical compounding to adverse drug events (ADEs) and antimicrobial resistance (AMR)

IntroductionPharmaceutical compounding, a practice of tailoring medications to individual patient needs, is integral to healthcare but poses potential risks, including adverse drug events (ADEs) and antimicrobial resistance (AMR). Understanding healthcare professionals' knowledge and perceptions on these issues is crucial for enhancing patient safety.ObjectivesThis study aimed to assess the practice and perceptions of healthcare professionals regarding the contribution of inappropriate pharmaceutical compounding to ADEs and AMR at Pawi General Hospital in the Metekel Zone, Benishangul-Gumuz Region.MethodsA crossectional study design was employed, involving a self-administered questionnaire distributed to healthcare professionals, including pharmacists, physicians, and nurses. STATA version 17 was used for analysis. Descriptive Analysis was used to summarize demographic characteristics of participants. The normality of the data was tested using a Shapiro wilk test. The mean standard deviations (SD) and percentages (%) of the variables were calculated.ResultsThe study was conducted among 120 healthcare professionals actively involved in patient care and pharmaceutical services within the hospital. The result of the study indicates varying levels of practice among healthcare professionals. The perceptions on the contribution of inappropriate compounding to ADEs and AMR differ across disciplines. The majority (75.83%) of the respondents deemed compounded medications in patient care as very important. A significant majority (61.67%) of respondents expressed being very concerned about the contribution of inappropriately compounded medication to AMR and ADEs.ConclusionsThis study indicated the need for targeted educational interventions to enhance healthcare professionals' understanding of inappropriate pharmaceutical compounding risks. The development of standardized training programs, regular updates on best practices, and collaborative efforts among healthcare professionals is essential for promoting patient safety, minimizing adverse events, and contributing to effective antimicrobial stewardship.

Factors associated with elevated SARS-CoV-2 immune response in children and adolescents.

Understanding the distinct immunologic responses to SARS-CoV-2 infection among pediatric populations is pivotal in navigating the COVID-19 pandemic and informing future public health strategies. This study aimed to identify factors associated with heightened antibody responses in children and adolescents to identify potential unique immune dynamics in this population. Data collected between July and December 2023 from the Texas Coronavirus Antibody REsponse Survey (Texas CARES), a statewide prospective population-based antibody survey among 1-to-19-year-old participants, were analyzed. Each participant had the following data available for analysis: (1) Roche Elecsys® Anti-SARS-CoV-2 Immunoassay for Nucleocapsid protein antibodies (Roche N-test), (2) qualitative and semi-quantitative detection of antibodies to the SARS CoV-2 spike protein receptor binding domain (Roche S-test), and (3) self-reported antigen/PCR COVID-19 test results, vaccination, and health status. Statistical analysis identified associations between participant characteristics and spike antibody quartile group. The analytical sample consisted of 411 participants (mean age 12.2 years, 50.6% female). Spike antibody values ranged from a low of 6.3 U/ml in the lowest quartile to a maximum of 203,132.0 U/ml in the highest quartile in the aggregate sample. Older age at test date (OR = 1.22, 95% CI: 1.12, 1.35, p < .001) and vaccination status (primary series/partially vaccinated, one or multiple boosters) showed significantly higher odds of being in the highest spike antibody quartile compared to younger age and unvaccinated status. Conversely, fewer days since the last immunity challenge showed decreased odds (OR = 0.98, 95% CI: 0.96, 0.99, p = 0.002) of being in the highest spike antibody quartile vs. more days since last immunity challenge. Additionally, one out of every three COVID-19 infections were asymptomatic. Older age, duration since the last immunity challenge (vaccine or infection), and vaccination status were associated with heightened spike antibody responses, highlighting the nuanced immune dynamics in the pediatric population. A significant proportion of children/adolescents continue to have asymptomatic infection, which has important public health implications.

The RESIST Senior Individuals Cohort: Design, participant characteristics and aims.

The number of older adults worldwide is growing exponentially. However, while living longer, older individuals are more susceptible to both non-infectious and infectious diseases, at least in part due to alterations of the immune system. Here, we report on a prospective cohort study investigating the influence of age on immune responses and susceptibility to infection. The RESIST Senior Individuals (SI) cohort was established as a general population cohort with a focus on the elderly, enrolling an age- and sex-stratified sample of 650 individuals (n = 100 20-39y, n = 550 61-94y, 2019-2023, Hannover, Germany). It includes clinical, demographic, and lifestyle data and also extensive biomaterial sampling. Initial insights indicate that the SI cohort exhibits characteristics of the aging immune system and the associated susceptibility to infection, thereby providing a suitable platform for the decoding of age-related alterations of the immune system and unraveling the molecular mechanisms underlying the impaired immune responsiveness in aging populations by exploring comprehensive, unbiased multi-omics datasets.

The implications of incorporating nutritional supplements into the treatment regimen for children aged 5-12 years with Visceral Leishmaniasis in Baringo and West Pokot counties in Kenya.

Purpose: The purpose of this article is to inform the Ministry of Health Management and all stakeholders in Kenya, the importance of the intervention, fills gaps, and provides guidance on future research direction to accelerate control and eventually eliminate Leishmaniasis. This will also shed new light on the importance of micronutrients and trace elements and their role in immunology, patient outcomes, and the physiology of Visceral Leishmaniasis (VL). The results of this study will also pave way to explore possibilities to fill the research gaps and address challenges like the resistance and relapse of the infection, in patients with VL. Furthermore, this study may help in developing evidence-based strategies related to malnutrition and trace elements, which may be implemented in the eradication program of VL. Materials and Methods: A quasi-experimental study design was conducted in Kenya from January 2022 to March 2022 in 204 VL-infected children aged 5-12 years. Demographic and clinical data were abstracted from questionnaires and lab forms. Descriptive and inferential analyses were conducted to determine the effect of the intervention on VL outcomes among the study children. Variables with a P-value &lt; 0.05 were considered statistically significant. A total of 204 VL study participants, 102 in each intervention and comparison group were included in this study. Baseline characteristics of the study participants were taken and recorded. The treatment and intervention were started and the trend of BMI, body temperature, vitamins A, B12, C, and D together with minerals Zinc, iron, and iodine levels were monitored weekly for four weeks to determine their effect on the treatment outcomes. Findings: The results showed that the outcome of administering the micronutrients is significant at 5% level, indicating that the intervention has a favorable effect. The micronutrients increased their levels in the body by increasing BMI, reducing spleen size, and controlling the body temperature of the study participants. In conclusion, the intervention accelerated the recovery from VL. Implications to Theory, Practice and Policy: This study was informed by the previous researchers' outputs (Mashayekhi Goyonlo V, 2020) indicating that administering the anti-leishmaniasis treatment alone will not yield a favorable treatment outcome in Visceral Leishmaniasis patients and also a study by Nweze JA, Nweze EI (2019) which indicated that malnourished patients with VL had an unfavorable outcome, which was recurrence in 21.4% and also that serum micronutrients levels favor good treatment outcome in Visceral Leishmaniasis. It is therefore important to note that Baringo and West-Pokot Counties, where the present study was conducted, are the Counties in Kenya with the highest percentage of VL patients. The study’s outcomes highlight the potential benefits of micronutrients to improve treatment outcomes in this regard, we recommend that the MOH should encourage the integration of micronutrients with the VL treatment in Baringo and West Pokot Counties. This research provides this new insight indicating that micronutrients affect the nutritional status and the treatment outcomes of VL by controlling body temperature, improving BMI, decreasing spleen size, negative VL tests, and therefore there is need to incorporate micronutrients to the treatment of children with VL. This study also raises several questions that warrant further investigation, such as the research on all the other micronutrients that were not analyzed in this study.

The Optimal Approach to Surgical Management of Goblet Cell Carcinoid of the Appendix: A Systematic Review.

Goblet cell carcinoid (GCC) is a rare and poorly understood appendiceal neoplasm, exhibiting mixed histological and aggressive clinical features. Current guidelines recommend right hemicolectomy in all cases, although there is conflicting evidence that appendicectomy alone may be sufficient. This review aims to identify the optimal surgical management for appendiceal GCC. A systematic review was performed by searching MEDLINE, Embase, Scopus and the Cochrane Register of Controlled Trials. Randomised controlled trials, cohort studies or large case series (>5 patients) reporting clinical outcomes for patients undergoing surgical management of GCC of the appendix were included. Outcomes extracted included participant and tumour characteristics, type of surgery and survival data. A total of 1341 studies were retrieved. After duplicate removal, 796 titles were screened for relevance prior to abstract and full text review. A total of six studies were included for analysis, comprising 3177 patients-1629 females and 1548 males. The median age ranged from 51 to 72 years. A total of 2329 patients underwent right hemicolectomy, while 824 were treated with appendicectomy only. Overall, the included studies report increased survival in patients undergoing right hemicolectomy compared to appendicectomy alone. A meta-analysis was not possible due to insufficient data reported in the published literature to date. There is no consensus regarding the optimal surgical management of appendiceal GCC, as outcomes-based data comparing surgical interventions are lacking. It is possible that some patients with favourable features are overtreated. The absence of robust evidence to support a more conservative approach means that right hemicolectomy remains the standard of care for all patients, in keeping with current international guidelines. The rarity of this condition and limited data in the published studies remain barriers to evidence-based best clinical practice.

The Impact of a Gamified Intervention on Daily Steps in Real-Life Conditions: Retrospective Analysis of 4800 Individuals.

Digital interventions integrating gamification features hold promise to promote daily steps. However, results regarding the effectiveness of this type of intervention are heterogeneous and not yet confirmed in real-life contexts. This study aims to examine the effectiveness of a gamified intervention and its potential moderators in a large sample using real-world data. Specifically, we tested (1) whether a gamified intervention enhanced daily steps during the intervention and follow-up periods compared to baseline, (2) whether this enhancement was higher in participants in the intervention than in nonparticipants, and (3) what participant characteristics or intervention parameters moderated the effect of the program. Data from 4819 individuals who registered for a mobile health Kiplin program between 2019 and 2022 were retrospectively analyzed. In this intervention, participants could take part in one or several games in which their daily step count was tracked, allowing individuals to play with their overall activity. Nonparticipants were people who registered for the program but did not take part in the intervention and were considered as a control group. Daily step counts were measured via accelerometers embedded in either commercial wearables or smartphones of the participants. Exposure to the intervention, the intervention content, and participants' characteristics were included in multilevel models to test the study objectives. Participants in the intervention group demonstrated a significantly greater increase in mean daily steps from baseline than nonparticipants (P<.001). However, intervention effectiveness depended on participants' initial physical activity. The daily steps of participants with <7500 baseline daily steps significantly improved from baseline both during the Kiplin intervention (+3291 daily steps) and the follow-up period (+945 daily steps), whereas participants with a higher baseline had no improvement or significant decreases in daily steps after the intervention. Age (P<.001) and exposure (P<.001) positively moderated the intervention effect. In real-world settings and among a large sample, the Kiplin intervention was significantly effective in increasing the daily steps of participants from baseline during intervention and follow-up periods compared to nonparticipants. Interestingly, responses to the intervention differed based on participants' initial steps, with the existence of a plateau effect. Drawing on the insights of self-determination theory, we can assume that the effect of gamification could depend of the initial motivation and activity of participants.

The effect of a single dose of methylphenidate on attention in children and adolescents with ADHD and comorbid Oppositional Defiant Disorder.

The co-occurrence Oppositional Defiant Disorder (ODD) in children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) has been associated to difficulties in regulating adverse states, elevated functional impairment, deficits in Executive Functions and high risk for psychopathology. Recent studies have shown that ODD is a negative predictor of a positive response to methylphenidate (MPH) treatment for ADHD symptoms in children and adolescents and that patients with a diagnosis of comorbid ADHD and ODD are less likely to respond favorably to pharmacological treatment with MPH. We conducted a naturalistic study to understand the clinical characteristics of drug-naïve children and adolescents with ADHD that influence the response to MPH by measuring the effect on attention. Specifically, we investigated whether a single dose of MPH differently affects the performance of 53 children and adolescents with ADHD with or without ODD comorbidity. In addition, participant characteristics such as symptom severity, functional impairment, and associated behavioral and emotional symptoms at baseline were examined to better understand what aspects affect the response to MPH. We found that a single dose of MPH improved the attention of children and adolescents with ADHD without ODD more than those with comorbid ADHD and ODD, resulting in reduced reaction times. Our findings indicated that children and adolescents with comorbid ADHD and ODD and those with ADHD alone did not exhibit differences in measures of attention prior to taking MPH, nor in demographic variables (age, intelligence quotient, gender), clinical characteristics related to symptom severity, and adaptive behaviors. However, we observed differences between the two groups in certain behavioral aspects, including the Dysregulation Profile and disruptive behaviors. Assessing symptoms in combination with the presence of ADHD can be beneficial in determining which individuals would derive the greatest benefits from treatment.

The mediating effect of self-efficacy on social support and cancer screening behavior among Chinese women: a cross-sectional study

BackgroundBreast and cervical cancer are the most common cancers in women, and are associated with high morbidity and mortality rates. Cancer screening can facilitate early diagnosis, reduce mortality, and ease the burden of cancer. Social support and self-efficacy are strongly associated with cancer screening behavior. The present study aimed to explore the mediating effect of self-efficacy on social support and cancer screening behavior.MethodsIn this cross-sectional survey study conducted from June to October 2023, 312 women aged 35–65 years were recruited from the East Coast area of China. A general information questionnaire, cancer screening behavior questionnaire, social support scale and self-efficacy scale were used to collect data. Descriptive statistics were used to analyze the general characteristics of participants; one-way analysis of variance was used to test for differences in the measured variables; and Pearson’s correlation analyses were used to describe the relationship among social support, self-efficacy, and cancer screening behavior. A mediation model was constructed and analyzed using the PROCESS macro for SPSS.ResultsThe mean (standard deviation) screening behavior score for breast cancer and cervical cancer was 3.98 (2.79), representing an intermediate level. Self-efficacy was closely related to social support and cancer screening behavior. Social support showed a significant positive correlation with self-efficacy (r = 0.37, p < 0.01) and cancer screening behavior (r = 0.18, p < 0.01). Self-efficacy was also significantly positively correlated with cancer screening behavior (r = 0.19, p < 0.05). Self-efficacy showed a full mediating effect between social support and cancer screening behavior, with an explanatory power of 32%.ConclusionsThe findings emphasize the need to increase women’s level of social support and self-efficacy, which in turn can increase women’s participation in breast and cervical cancer screening.

Virtually Augmented Surgical Navigation in Endoscopic Sinus Surgery Simulation Training: A Prospective Trial of Repeated Measures.

The objective of this study was to explore the educational utility of virtually augmented surgical navigation (VASN) in simulation training for endoscopic sinus surgery. Prospective trial using within-subjects design. Single academic institution. Otolaryngology trainees (n = 15) were enrolled in a prospective trial of repeated measures. Participants performed unilateral functional endoscopic sinus surgery (FESS) on a 3-dimensional-printed sinus model without instruction. Participants then underwent educational intervention incorporating VASNtools-featuring anatomic overlay delineations, virtual planning points, proximity alerts, digital measurements, as well as artificial intelligence-generated endoscopic viewpoints. With the VASN tools activated, participants then performed FESS on the contralateral side of the model. Primary outcomes of interest included number of major complications, time to complete anterior fess, steps completed, and technical skills score. Descriptive statistics were performed to describe participant characteristics and bivariate analysis were used to evaluate differences in subjective and objective outcome measures. A majority (93%) of residents strongly agreed that simulation intervention improved their confidence in surgical skills related to FESS. Complications decreased from 13 instances to 3 following interventions. Initial technical skills score of 45.2 increased to 54.4 postintervention (P < .0001) and global score also improved by 4.6 points on average (P < .001). Time to anterior FESS decreased from 1356 to 915seconds (P = .006) and average number of completed surgical steps increased from 3.3 to 4.6 (P < .001). This simulation study contributes to growing evidence supporting utility of advanced technology in surgical education. Results suggest that VASN serves as a beneficial adjunct in FESS simulation training.

Mpox, sexually transmitted infections and combination prevention: insights from a major cohort in Rio de Janeiro, Brazil.

To evaluate the prevalence and characteristics of concurrent bacterial sexually transmitted infections (bSTIs) among individuals with mpox. Prospective cohort study of participants aged 18 years or older with confirmed mpox conducted in Rio de Janeiro, Brazil. This cross-sectional analysis includes only participants who underwent bSTI testing at baseline between June 2022 and January 2024. Participants were offered testing for chlamydia/gonorrhea (NAAT, anorectal swabs) and syphilis (active diagnosis if VDRL ≥ 1/8). Baseline prevalence of bSTIs was calculated, and participant characteristics were described based on concomitant bSTI diagnosis (yes/no). Chi-squared/Fisher's tests were used for qualitative variables, and the Wilcoxon rank-sum test for quantitative variables. Out of 634 enrolled participants, 538 (84.9%) were tested for STIs and included in this analysis, mostly cisgender men, aged 30-39 years with postsecondary education. Overall prevalence of concomitant bSTI was 37.3%, mainly syphilis, followed by chlamydia and gonorrhea. Half of the participants were living with HIV, and one third was on HIV pre-exposure prophylaxis. Concomitant bSTI diagnosis at the time of mpox assessment was associated with being aged 30-39 years, self-identifying as cisgender men, having HIV-positive status, reporting proctitis symptoms and reporting any STI in the past 12 months. Our data reveals a notable prevalence of concomitant bSTIs among participants with confirmed mpox at a prominent infectious diseases' referral center in Rio de Janeiro, Brazil. These findings underscore the importance of integrating mpox into the differential diagnosis of anogenital manifestations and the promotion of combination prevention strategies within sexual healthcare services.

Efficacy of Motor Imagery in the Rehabilitation of Stroke Patients: A Scope Review

This review examines the efficacy of motor imagery (MI) as a supplementary rehabilitation technique for stroke patients. Nine randomized controlled trials (RCTs) were analyzed, highlighting MI's potential to enhance motor recovery, mobility, balance, and psychological well-being. Significant improvements in upper-limb function were observed with combined mental and physical practice, evidenced by notable gains in Fugl-Meyer Assessment (FMA) and Action Research Arm Test (ARAT) scores. MI-based exercise programs improved mobility and balance in elderly patients, reducing fall risk as measured by the Timed Up and Go (TUG) test and Berg Balance Scale (BBS). MI was also found to enhance self-efficacy and functional performance, with significant increases in Functional Independence Measure (FIM) and General Self-Efficacy Scale (GSES) scores. Neuroimaging studies revealed that MI activates cortical areas associated with motor control, supporting its role in promoting neural plasticity. Despite these promising results, the heterogeneity in participant characteristics, stroke severity, and MI protocols across studies poses challenges to standardization. Additionally, small sample sizes and reliance on self-report measures limit the generalizability of findings. Nevertheless, MI's low cost, minimal risk, and ease of integration into existing rehabilitation protocols make it a valuable adjunct to physical therapy. Standardized guidelines and personalized MI exercises tailored to individual needs are essential for maximizing benefits. Integrating MI into clinical practice can significantly enhance both physical and psychological recovery outcomes for stroke patients, offering a comprehensive approach to rehabilitation.

Effect of wearable activity trackers on physical activity in children and adolescents: a systematic review and meta-analysis

Physical inactivity in children and adolescents has become a pressing public health concern. Wearable activity trackers can allow self-monitoring of physical activity behaviour and promote autonomous motivation for exercise. However, the effects of wearable trackers on physical activity in young populations remain uncertain. In this systematic review and meta-analysis, we searched PubMed, Embase, SPORTDiscus, and Web of Science for publications from database inception up to Aug 30, 2023, without restrictions on language. Studies were eligible if they were randomised controlled trials or clustered randomised controlled trials that examined the use of wearable activity trackers to promote physical activity, reduce sedentary behaviours, or promote overall health in participants with a mean age of 19 years or younger, with no restrictions on health condition or study settings. Studies were excluded if children or adolescents were not the primary intervention cohort, or wearable activity trackers were not worn on users' bodies to objectively track users' physical activity levels. Two independent reviewers (WWA and FR) assessed eligibility of studies and contacted authors of studies if more information was needed to assess eligibility. We also searched reference lists from relevant systematic reviews and meta-analyses. Systematic review software Covidence was used for study screening and data extraction. Study characteristics including study setting, participant characteristics, intervention characteristics, comparator, and outcome measurements were extracted from eligible studies. The two primary outcomes were objectively measured daily steps and moderate-to-vigorous physical activity. We used a random-effects model with Hartung-Knapp adjustments to calculate standardised mean differences. Between-study heterogeneity was examined using Higgins I2 and Cochran Q statistic. Publication bias was assessed using Egger's regression test. This systematic review was registered with PROSPERO, CRD42023397248. We identified 9619 studies from our database research and 174 studies from searching relevant systematic reviews and meta-analyses, of which 105 were subjected to full text screening. We included 21 eligible studies, involving 3676 children and adolescents (1618 [44%] were female and 2058 [56%] were male, mean age was 13·7 years [SD 2·7]) in our systematic review and meta-analysis. Ten studies were included in the estimation of the effect of wearable activity trackers on objectively measured daily steps and 11 were included for objectively measured moderate-to-vigorous physical activity. Compared with controls, we found a significant increase in objectively measured daily steps (standardised mean difference 0·37 [95% CI 0·09 to 0·65; p=0·013]; Q 47·60 [p<0·0001]; I2 72·7% [95% CI 53·4 to 84·0]), but not for moderate-to-vigorous physical activity (-0·08 [-0·18 to 0·02; p=0·11]; Q 10·26 [p=0·74]; I2 0·0% [0·0 to 53·6]). Wearable activity trackers might increase daily steps in young cohorts of various health statuses, but not moderate-to-vigorous physical activity, highlighting the potential of wearable trackers for motivating physical activity in children and adolescents. More rigorously designed trials that minimise missing data are warranted to validate our positive findings on steps and to explore possible long-term effects.
