Ablation index (AI), a novel lesion quality marker, includes contact force, time, and power of radiofrequency (RF) application, but not regional variation in wall thickness within the wide antral catheter ablation (WACA) circle. This study explored the relationships among AI target value, atrial wall thickness, and gap formation within the WACA circle in patients with paroxysmal atrial fibrillation (PAF).

We evaluated 102 consecutive patients (mean age, 65 ± 9 years) with PAF who underwent AI-guided WACA for ipsilateral pulmonary vein isolation (PVI). Each WACA circle was subdivided into eight segments, and overall 7143 RF applications were delivered, including 125 gaps in PVI ablation lines. For each RF tag within the ablation circle, we collected data on ablation lesion depth surrogates (time of application, delivery power, impedance drop, average contact force, force-time integral [FTI], and AI) and left atrial wall thickness measured by multidetector computer tomography scanning.

The anterior and roof walls were the thickest segments of the ablation circle, in which 85.8% of gaps concentrated, while the posterior and inferior walls were the thinnest. Gap formation was significantly associated with FTI, AI, wall thickness, FTI/wall thickness, and AI/wall thickness. AI/wall thickness had the highest predictive value for gap formation, with a cutoff of 195.6 au/mm for effective ablation.

In AI-guided PVI of PAF, AI/wall thickness by normalizing myocardial thickness variation along the WACA circle was a strong predictor of gap formation, with a target of 195.6 au/mm appearing suitable for effective ablation.

This study aimed to determine the effect of shyness levels of women on early diagnosis attitudes towards cervical cancer.

The study was planned as descriptive. Data were collected from women in the 18-49 age group who applied to family health centers in Sivas. The descriptive information form of women, the Shyness Scale, and the Attitude Scale for Early Diagnosis of Cervical Cancer were used. A total of 303 women were included in the study.

A significant negative correlation was detected between shyness levels of women and the perceived benefit, while a significant positive correlation was determined between shyness levels and perceived severity.

In this study, the perceived benefit increased as the shyness levels of women decreased.

In this study, the perceived benefit increased as the shyness levels of women decreased.Carey et al1 recently proposed that HBV pregenomic RNA (pgRNA) is a sensitive indicator of covalently closed circular DNA (cccDNA) transcription status in patients receiving nucleos(t)ide analogue therapy (NA) for hepatitis B. pgRNA is transcribed from the cccDNA minichromosome and therefore reflects a product of cccDNA transcriptional activity and its prevalence within HBV-infected cells. They observed that some patients reached pgRNA negativity 12 months of NA, suggesting a surprisingly rapid decline in transcriptional activity/prevalence of cccDNA.

Involving communities in school health has been purported as a practice integral to supporting a Whole School, Whole Community, Whole Child (WSCC) approach. Although community collaboration is often included in school-based health initiatives, there is little research considering methods for increasing community engagement. The purpose of this study was to identify effective school-based health interventions documenting changes in community engagement.

Academic experts and school stakeholders guided procedures for a systematic review of studies published from 1987-2017 and gray literature (ie, best practice documents; policy documents, etc.) on comprehensive school health interventions including community engagement as a targeted outcome.

The search identified 9 studies addressing community as an outcome of school-based health interventions; types of partnership mechanisms and partners' roles were classified.

Although involving communities is a WSCC component and commonly recommended as a strategy fundamental to school health, there is little empirical research examining effective strategies for engaging communities and engagement is often not measured as part of intervention studies. Further measurement and research in engaging communities in school health is warranted.

Urban black adolescents' wellbeing in the early high school years can be negatively impacted by exposure to racial discrimination. These impacts may be buffered by supportive relationships with adults at school. We considered both the protective and promotive effects of culturally responsive teachers and caring school police on school engagement for students exposed to racial discrimination across settings.

This study leveraged baseline student report from a sample of urban, predominantly black high school students with elevated teacher-rated levels of aggressive behavior (N=397 9th graders; 91.2% black; 50.4% male; J=10 schools). Using a path model with full-information maximum likelihood estimation, we examined the associations of racial discrimination, teacher cultural responsiveness, and school police caring in relation to school engagement and school disconnection, adjusting for covariates, including family racial socialization.

Frequency of racial discrimination was significantly associated with lheir teachers are culturally responsive may feel more engaged at school. Interventions to promote teachers' and school police officers' cultural responsiveness and caring may improve engagement among at-risk urban youth who experience racial discrimination.
