Routine immunization programs may reduce antibiotic use, but few studies have comprehensively examined their impact on antibiotic utilization. We aimed to explore temporal trends in vaccination and antibiotic use among young children in the United States.

Ecological study using the Merative® MarketScan Commercial Claims and Encounters database.

We analyzed claims data on pediatric vaccine uptake (pneumococcal conjugate, Haemophilus influenzae type b, diphtheria-tetanus-pertussis, and influenza) and antibiotic prescriptions and antibiotic-treated respiratory tract infections among US children <5 years during 2000–2019. Vaccination status was assessed annually, and children were categorized based on receipt of all four vaccines, 1–3 vaccines, or no vaccines. Antibiotic prescriptions were classified by spectrum and drug class. Respiratory infections included otitis media, pharyngitis, pneumonia, sinusitis, and viral infections.

Among 6.7 million children, vaccine uptake increased from 32.5% receiving all four vaccines in 2004 to 66.8% in 2019. During this period, overall antibiotic prescriptions decreased from 1.89 to 1.01 per person-year, with the greatest reductions in macrolides (73.3%) and broad-spectrum antibiotics (57.0%). Antibiotic-treated respiratory tract infections declined from 2.43 to 1.61 episodes per person-year, with the largest decreases in sinusitis (64.7%) and pharyngitis (39.8%).

The findings suggest a temporal association between routine childhood immunization uptake and reduced antibiotic utilization. Although immunization programs are primarily aimed at protecting children from vaccine-preventable diseases, their potential role in complementing antimicrobial stewardship efforts and other factors influencing antibiotic reduction warrants further investigation through more rigorous study designs.

Nonsuicidal self-injury (NSSI) is defined as deliberate and direct damage to one’s body tissues without any suicidal intent. NSSI is now recognized as a major risk factor for suicide and is prevalent among adolescents, with prevalence rates ranging from 7.5% to 46.5%, leading to increased interest in the pathophysiology of NSSI. This study aimed to examine cortical gyrification morphology, a neurobiological index of cortical folding and patterning, among unmedicated individuals with NSSI, which is prevalent in adolescents and young adults.

The main objective of this study is to compare cortical morphological abnormalities between individuals with NSSI and controls in terms of the local gyrification index (LGI), the ratio of the smooth cortical surface area at each vertex to the corresponding sulcal folds. In addition, we hypothesized that the LGI, a stable neurodevelopmental marker of cortical and subcortical circuit intergrity, would correlate with clinical measures in youth with NSSI.

A total of 101 individuals with NSSI and 100 age-, gender-, and handedness-matched controls completed self-report questionnaires and structural magnetic resonance imaging (MRI) data were acquired on a 3T Siemens scanner. A surface-based analysis was conducted using the Computational Anatomy Toolbox (CAT12) in Statistical Parametric Mapping (SPM12). Partial correlation analysis was also performed using R software to investigate the association between the LGI values extracted from the region of interest (ROI) and clinical symptoms, including depression, anxiety, emotion dysregulation, and anhedonia in individuals with NSSI.

Individuals with NSSI showed significantly increased LGI in the right insula sulcus and left superior temporal sulcus (STS), along with decreased LGI in the right calcarine and left superior parietal sulcus (SPS), compared to controls (5000 permutation correction, threshold-free cluster enhancement with a threshold of p < .05). In addition, higher LGI in left STS was correlated with greater scores of the Beck Anxiety Inventory (r = 0.22, p < .05) and of the Impulse Control Difficulties subscale of the Difficulties in Emotion Regulation Scale (r = 0.34, p < .001). Conversely, reduced LGI of the right calcarine was associated with a higher score on the Anhedonia subscale of the Beck Depression Inventory (r = -0.23, p < .05) within individuals with NSSI.

This study identified hypergyria in the right insular and left STS and hypogyria in the right calcarine and left SPS in individuals with NSSI. The former pattern was associated with anxiety and impulse control difficulties, and the latter was with anhedonia. This study is the first to alter distinct neurodevelopmental patterns of local gyrification and their correlations with clinical manifestations in individuals with NSSI.

Human faces generally attract immediate attention. However, it has been found that children with autism spectrum disorder (ASD) tend to allocate relatively less attention to faces. Previous research showed that typically developing children (TD) exhibited an attentional bias to angry faces, regardless of their anxiety levels, but it’s unclear if this applies to children with ASD. Therefore, the present study aims to investigate attentional bias induced by angry and/or happy faces in children with ASD.

We explored attentional bias toward angry faces in both TD children and children with ASD. We hypothesize that while TD children will show attentional capture effects in response to angry faces, children with ASD will not exhibit such attentional bias to facial stimuli, irrespective of their emotional content.

By now, five ASD participants (all male) and 34 TD participants (17 male), aged 6-12, have completed a continuous performance task. In this task, irrelevant distractors (angry or happy faces) appeared and disappeared abruptly, while the orientation of the target changed every 1,250 ms. Participants were asked to respond as quickly and accurately as possible to the orientaiton of the target. We designated the time when the distractor first appeared as T1, and subsequent time intervals at 1,250 ms increments were labeled as T2, T3, and T4. The time intervals when no distractor was present were labeled as TB (baseline). If the reaction time (RT) at T1 was significantly slower compared to TB, it indicated attentional bias by the distractor.

For the RT data, separate repeated measures ANOVAs with 2 (emotion) * 5 (time) factors were conducted for each group. The results revealed a significant main effect of time (F(4, 132) = 17.59, p < .01) and a significant interaction between emotion and time (F(3.27, 107.74) = 4.92, p < .01) only in TD. Post hoc t-tests indicated that TD children exhibited significantly slower RT at T1 compared to TB, but this difference was observed only for angry faces (t(33) = 4.84, p < .01). In contrast, no significant effect was found in children with ASD. In other words, TD demonstrated attentional bias only when exposed to angry faces, while ASD children did not exhibit attentional bias to either emotion.

This study aimed to investigate attentional bias to angry faces in both TD and ASD children. The results indicate that TD children exhibited an attentional bias when exposed to angry faces, whereas ASD children did not display such bias. These findings are consistent with previous research suggesting that TD children tend to show attentional bias towards angry faces, regardless of their anxiety levels. Furthermore, the absence of attentional bias to angry faces in ASD suggests that their characteristic of reduced attention to faces may contribute to the lack of attentional bias towards angry faces.

People experience various negative emotions when they encounter stressful events, and these negative emotions contribute to the onset of illnesses. These emotional responses are not limited to just one; a person can experience multiple emotions at once, and the primary emotional reactions can vary depending on the severity and duration of the illness or life events. This is reason why we created a self-report scale to assess short-term emotional responses, focusing on the current emotional state experienced subjectively by patients.

The purpose of this study was to develop an affective response scale (ARS) and examine its validity and reliability.

We established clusters of affective via a literature review and developed preliminary items based on the structure. We conducted expert content validation to converge on the final items, followed by construct validity and reliability analyses.

The research findings indicate that the Affective Response Scale was composed of three main dimensions: anxiety, anger, and depression. Content validity results confirmed the validity of most items. The scale developed in this study was found to be valid in both exploratory and confirmatory factor analyses, and it was identified to be stable and consistent through the analysis of the internal reliability.

These results indicate that the ARS is highly reliable and valid, and that it can be utilized as an effective measure of the patient’s emotion and its severity.

It has been several years since the World Health Organization (WHO) advocated for shared decision-making(SDM) models when developing treatment plans for individuals with mental illnesses. It is emphasizing the importance of actively involving patients in expressing their opinions and sharing treatment-related information. However, few clinicians accept patients’ subjective views in clinical practice. Given that patients’ subjective beliefs about their symptoms significantly impact treatment satisfaction, prognosis, and adherence, it is essential to assess these perceptions. However, few studies have been conducted to assess patients’ subjective beliefs, their mental representation, of their disease. Therefore, this study aims to develop Interview that enable the utilization of patients’ cognitive representations of their mental illnesses in clinical practice.

The primary objective of this study is to develop a semi-structured interview and a self-report scale to evaluate patients’ mental representations of their illnesses. Subsequently, validate the reliability and validity of these tools as psychological assessments.

An initial structure for both the semi-structured interview and self-report scale was established through a literature review of existing disease representation measurements. Subsequently, expert panel discussions and further literature reviews were conducted to refine the structure and content of both tools. Content validity for both the interview and self-report scale was assessed by a panel of nine experts and a group of ten students. Following this, the developed interview tool was subjected to a validity analysis with clinical patients using Missick’s six validity criteria(Content, Substantive, Structural, Generalizability, External, Consequential).

Content validity index (CVI) values for the overall structure indicated that all subdomains scored above 0.8, demonstrating the appropriateness of the interview tool’s five subdomains: symptoms, causes, temporal aspects, impact, and treatment and control. Content validity assessment for individual items revealed that some items within the “causes of the disease” subdomain, specifically stress-related factors, scored below 0.6, prompting necessary item modifications. All other factors achieved CVI scores of 0.6 or higher. Facial validity assessment yielded favorable results for all items in the self-report scale. All validity was demonstrated to be satisfactory.

This study has provided evidence that the developed tools are reliable and valid instruments for measuring patients’ perceptions of their illnesses, offering a trustworthy means to assess these vital cognitive representations in clinical practice.

The objective of this research was to compare trends in publications of network meta-analyses (NMAs) in cardiovascular diseases (CVDs) in Asia-Pacific (APAC; China, Japan, Singapore, South Korea, Thailand) and Europe (United Kingdom [UK], Germany, France, Spain, Italy), with a focus on volume, collaborations and methods.

Freely available NMAs assessing pharmacological or surgical interventions for CVD in terms of mortality or major adverse cardiovascular events, published in 2012 or later, by authors affiliated with institutions in the target countries were identified via MEDLINE and Embase. CVDs were grouped using the International Classification of Diseases, Tenth Edition (ICD-10).

Across the 193 publications identified, heart diseases such as atrial fibrillation, aortic stenosis and heart failure (ICD-10 I30-I52) were the most common indications reported (38%). The majority of publications involved authors in APAC countries (63%) and 40% from Europe. Cumulative numbers of publications from APAC surpassed those from Europe from 2018 onwards. Authors were largely affiliated with institutions in China (50%), the UK (20%) and Italy (20%). One hundred and forty-five publications were by authors affiliated with institutions in a single country; 91 percent of publications from APAC and 44 percent from Europe, indicating different patterns of collaboration within these regions. In terms of reporting methodologies, 39 percent of included publications did not specify whether a frequentist or Bayesian framework was used (43% in APAC, 34% in Europe). Among those that reported, the Bayesian framework was more commonly used.

Whilst there is a growing trend in NMA publication counts generally, the rate of increase in APAC was higher than Europe, particularly in the years following adoption of health technology assessment (HTA) procedures in APAC. The volume of publications not reporting the framework used was substantial, despite requirements for this in reporting guidelines e.g., PRISMA. Where reported, the Bayesian framework may have been favored due to its advocacy by some health technology assessment bodies.

Purposeful training and ongoing career support are necessary to meet the evolving and expanding roles of clinical research professionals (CRP). To address the training and employment needs of clinical research coordinators (CRCs), one of the largest sectors of the CRP workforce, we designed, developed, and implemented an online career navigation system, eMPACTTM (eMpowering Purposeful Advancement of Careers and Training).

A design-based research method was employed as an overarching approach that frames iterative design, development, and implementation of educational interventions. The five major phases of this project – conceptualization, task analysis for measurement development, algorithms development, algorithms validation, and system evaluation – presented specific goals and relevant methods.

The results reported how the eMPACTTM system was conceptualized, developed, and validated. The system allowed CRCs to navigate tailored training and job opportunities by completing their task competencies and career goals. The data sets could, in turn, support employees’ and training coordinators’ informed decisions about organizational training needs and recruitment. The early dissemination results showed steady growth in registered CRCs and diversity in users’ ethnicity and job levels.

The eMPACTTM service showed the possibility of supporting CRCs’ individual career advancement and organizational workforce enhancement and diversity. Long-term research is needed to evaluate its impact on CRC workforce development, explore key factors influencing workforce sustainability, and expand eMPACTTM service to other CRP sectors.

Three-dimensional chromatin interactions regulate gene expressions. The significance of de novo mutations (DNMs) in chromatin interactions remains poorly understood for autism spectrum disorder (ASD).

To investigate the genomic architecture of ASD in terms of non-coding de novo mutations and 3-dimensional chromatin interactions

We generated 813 whole-genome sequences from 242 Korean simplex families to detect DNMs, and identified target genes which were putatively affected by non-coding DNMs in chromatin interactions.

Non-coding DNMs in chromatin interactions were significantly involved in transcriptional dysregulations related to ASD risk. Correspondingly, target genes showed spatiotemporal expressions relevant to ASD in developing brains and enrichment in biological pathways implicated in ASD, such as histone modification. Regarding clinical features of ASD, non-coding DNMs in chromatin interactions particularly contributed to low intelligence quotient levels in ASD probands. We further validated our findings using two replication cohorts, Simons Simplex Collection (SSC) and MSSNG, and showed the consistent enrichment of non-coding DNM-disrupted chromatin interactions in ASD probands. Generating human induced pluripotent stem cells in two ASD families, we were able to demonstrate that non-coding DNMs in chromatin interactions alter the expression of target genes at the stage of early neural development.

Taken together, our findings indicate that non-coding DNMs in ASD probands lead to early neurodevelopmental disruption implicated in ASD risk via chromatin interactions.

Nurses are at an increased risk for work-related stress resulting in post-traumatic stress disorder (PTSD). They are susceptible due to frequent exposure to traumatic situations providing care for patients.

The purpose of this systematic review is to comprehensively review the content and characteristics of intervention programs for reducing the post-traumatic stress of nurses or nursing students, providing a basis for developing a standardized protocol for programs to promote the integrated health of nurses and protect them from stress events in clinical environments.

This is a systematic review. Participants (P) targeted nurses or nursing students; Intervention (I) included intervention programs for reducing post-traumatic stress; Comparison (C) was control groups provided with usual or no interventions ; and Outcomes (O) referred to changes in physical or emotional reactions toward post-traumatic stress. Two researchers searched four databases including PubMed, CINAHL, PsycINFO, and EMBASE with keywords such as “nurse,” “post-trumatic stress disorder,” “program,” and “intervention”. A total of 7,523 studies were searched and 10 studies were included for final analysis (Image 1). The Risk of Bias2 (Image 2) and the Risk of Bias for Non-randomized Study I (Image 3) were used to evaluate the quality the included studies.

The number of studies is increasing, with four studies published before 2020, and six studies published since, of which three in 2022. Definitions of trauma situations to which nurses are exposed included diverse elements such as patient death, workplace violence, the COVID-19 pandemic, and complex trauma experiences due to working environments. Most studies have provided multiple intervention sessions, which is appropriate considering the characteristics of PTSD. Most studies examined the secondary effects on mental health such as anxiety, depression, and burnout caused by stress rather than evaluating stress itself. The quality of the study was generally highly biased. The risk of bias increased for the two randomized controlled trials in terms of measurement outcomes and outcome description. The other eight non-randomized studies all included a self-reporting questionnaire of participants, leading to a risk of bias in terms of measurement outcomes.

Studies have been conducted to confirm the effectiveness of interventions given heightened concerns about PTSD in nurses. However, the concept of the trauma experienced by nurses was not integrally defined, and information on interventions was often limited. Efforts are required to improve the quality of research in terms of experimental study design.

Lamina-specific alterations of inhibitory circuitries have been considered the crucial pathogenesis of perceptual, cognitive and behavioral symptoms presented in schizophrenia and mood disorders. Especially, with emerging evidences indicating the close lamina-specific relationship between synaptic defects and γ-Aminobutyric acid (GABA)-related gene dysfunctions, it has been suggested the mRNA dysregulations of Tyrosine kinase B (TrkB) and Glutamate decarboxylase 67 (GAD67) could particularly be implicated in middle and deep layers of neocortex of patients with major psychiatric disorders.

Giving inquiries of whether defects of these mRNA levels in Orbitofrontal cortex (OFC) would be involved as lamina-specific patterns in individuals with schizophrenia and mood disorders.

We examined mRNA levels of BDNF, TrkB and GAD67 in each OFC layer I through VI. We analyzed data from postmortem brain tissue of the Stanley Neuropathology Consortium Integrative Database (SNCID). SNCID consists of 15 subjects in each of four groups (schizophrenia, bipolar disorder, major depression without psychotic features, and unaffected controls). All groups were matched for age, sex, race, brain pH and post-mortem interval.

We found TrkB mRNA levels to be significantly reduced in layer VI in both groups with schizophrenia (25.8%) and bipolar disorder (35.7%) compared with controls. GAD67 mRNA levels were also significantly reduced in layer III and IV in patients with schizophrenia (23.4% and 22.7%, respectively) and bipolar disorder (31.2% and 24.9%, respectively) compared with controls. Individuals with major depression showed only trends toward decreased mRNA levels of GAD67 in layer III and IV and of TrkB in layer VI compared with controls. TrkB mRNA levels in layer VI were significantly correlated with GAD67 mRNA levels in layer III (ρ=0.581, p=0.037) and IV (ρ=0.857, p<0.001) in subjects with bipolar disorder, but not in those with schizophrenia. When analyzed with partial correlation controlling the effects of pH and PMI, significance of correlation remained only between GAD67 mRNA in layer IV and TrkB mRNA in layer VI in individuals with bipolar disorder (ρ=0.768, p=0.006).

The resulting lamina-specific decreases in inhibitory tone across layers of OFC may contribute to the unrestrained irritability and violent behaviors in common shared by both patients with schizophrenia and bipolar disorder. Nonetheless, our findings indicate the obvious correlations between lamina-specifically altered TrkB and GAD67 mRNA levels in OFC might be a candidate for endophenotype of bipolar disorder.

Wolff–Parkinson–White syndrome is associated with sudden cardiac death from rapid conduction through the accessory pathway in atrial fibrillation. Adult patients are at higher risk for sudden cardiac death if the shortest-pre-excited-RR-interval in atrial fibrillation (SPERRI) is ≤250 milliseconds (msec) during electrophysiologic study. Exclusive conduction through the atrioventricular node in atrial fibrillation is presumed to convey lower risk. The shortest-pre-excited-paced-cycle-length with atrial pacing has also served as a marker for risk stratification.

To determine accessory pathway characteristic of patients undergoing induction of atrial fibrillation during electrophysiologic study.

We reviewed 321 pediatric patients that underwent electrophysiologic study between 2010 and 2019. Induction of atrial fibrillation was attempted on patients while on isoproterenol and SPERRI was measured if atrial fibrillation was induced. Shortest-pre-excited-paced-cycle-length (SPPCL) was determined while on isoproterenol.

Atrial fibrillation was induced in 233 (73%) patients. Of those, 104 (45%) patients conducted exclusively through the atrioventricular node during atrial fibrillation (Group A). The remaining 129 (55%) patients had some conduction through the accessory pathway (Group B). In Group A, SPPCL was 260 msec with 48 (46%) conducting through the accessory pathway at ≤250 msec. In Group B, SPPCL was 240 msec with 92 patients (71%) conducting at ≤250 msec (p < 0.05). In Group B, SPERRI was 250 msec and had a positive correlation with SPPCL (p < 0.001, R2 = 0.28). Almost half (46%) of those with exclusive conduction through the atrioventricular node in atrial fibrillation had rapid accessory pathway conduction with atrial pacing.

Conduction in atrial fibrillation during electrophysiologic study on isoproterenol via the atrioventricular node may not exclude high-risk accessory pathways in pediatric patients.

To investigate the effect of body mass index on hearing outcomes, operative time and complication rates following stapes surgery.

This is a five-year retrospective review of 402 charts from a single tertiary otology referral centre from 2015 to 2020.

When the patient's shoulder was adjacent to the surgeon's dominant hand, the average operative time of 40 minutes increased to 70 minutes because of a significant positive association between higher body mass index and longer operative times (normal body mass index group (<25 kg/m2) r = 0.273, p = 0.032; overweight body mass index group (25–30 kg/m2) r = 0.265, p = 0.019). Operative times were not significantly longer upon comparison of low and high body mass index groups without stratification by laterality (54.9 ± 19.6 minutes vs 57.8 ± 19.2 minutes, p = 0.127).

There is a clinically significant relationship between body mass index and operating times. This may be due to access limitations imposed by shoulder size.

This study primarily assessed ENT surgical trainees’ preferences for the qualities of disposable and reusable fibre-optic nasendoscopes. Secondary aims included eliciting trainees’ views on ENT surgery and climate change, and creating a single-centre per-use cost analysis for disposable and reusable fibre-optic nasendoscopes.

A cross-sectional study was formulated. An online survey consisting of multiple-choice and Likert-scale questions was distributed nationally. Cost analysis was performed using 2021–2022 data from the host institution.

Twenty-four trainees responded. Data on disposable fibre-optic nasendoscopes showed no difference in overall satisfaction (p = 0.244). Reusable fibre-optic nasendoscopes had a lower cost per use compared with disposable nasendoscopes at 5 years (4.7 per cent reduction) and 10 years (7.1 per cent reduction). Of the trainees, 79.2 per cent were supportive of climate-friendly initiatives within ENT surgery, and 25 per cent felt supported by their departments.

Trainees’ satisfaction with disposable and reusable fibre-optic nasendoscopes is similar. Cost analysis favours reusable fibre-optic nasendoscopes in the long term at the host institution. Empowering departments and trainees to pursue climate-friendly initiatives should be encouraged.

Direct gaze is the most important mediator of social interaction and communication. Existing studies have evaluated eye movements of patients with schizophrenia by presenting stimuli using photographs or pre-recorded videos, but few directly investigated gaze avoidance in real-world situations.

To investigate the correlation between gaze avoidance and psychopathology in patients with schizophrenia through eye movement measurements in real-life interpersonal situations.

We enrolled 52 clinically stable patients with schizophrenia. Psychopathology was evaluated using the Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scale. After presenting a visual stimulus, eye movements were measured with Tobii Pro Wearable Glasses 2, and deep learning-based emotional recognition using the residual masking network was used for neutral stimulus verification. Statistical analyses were performed using Pearson’s correlation and regression analyses.

Data of 45 participants with verified stimulus neutrality by deep learning image recognition were used for analysis. The first dwelling time was negatively correlated with the PANSS positive syndrome subscale (p=0.028), general psychopathology subscale (p=0.008), total score (p=0.008), 5-factor positive symptoms (p=0.035), and 5-factor depression/anxiety symptoms (p=0.008). The baseline-area of interest (AOI) pupil diameter change was positively correlated with PANSS 5-factor positive symptom scores (p=0.039). After adjusting for additional variables, the same items had a significant effect on the first dwelling time and baseline-AOI pupil diameter change.

Psychopathology, particularly positive symptoms, was associated with gaze avoidance and pupil diameter in patients with schizophrenia. Evaluating the characteristics of eye movements in patients with schizophrenia will enable better understanding of their symptoms.

Hwa-Byung is characterized by feelings of anger or resent about unreasonable social violence and trauma. Although Prevalence of Hwa-Byung is high in middle-aged, recently Hwa-Byung is occurred in young people. And it is suggested that young Hwa-Byung patients will show different patterns from middle-aged.

The purpose of present study was to qualitatively analyze young Hwa-Byung patients’ experiences of symptoms and psychological characteristics related to antecedent events of Hwa-Byung.

10 women aged 20s were Interviewed using semi-structured questionnaires to in-depth study on their experiences related to Hwa-Byung. The interview data were analyzed using phenomenological approach in order to understand the essence of experiences. In particular, it was analyzed through five steps according to Giorgi (1985). First, by repeatedly reading the material, recurring themes were identified. Second, the meaning units were divided to capture important parts of participants’ statements. Third, similar meaning units were grouped together. Fourth, the determined meaning units were described in psychological term. Finally, research data were integrated and presented according to the described meaning units. Reliability between coders was higher than the minimum reliability coefficient.

In symptoms, two themes and seven sub-themes were emerged. In psychological characteristics, three components and five sub-themes were derived. In particular, the antecedent events of young Hwa-Byung patients were related to vertical social relationships, suggesting that Hwa-Byung need to be understood under social context which make them angry.

Present study revealed the social context of Hwa-Byung by discussing the differences between young and middle-aged patients, and furthermore, differences between Hwa-Byung and depression, PTSD patients.
