Microorganism diversity and contamination risk in mosque rosaries and carpets.

BACKGROUND: Inevitably, the floors of mosques are contaminated with microorganisms, and the risk of pathogen transmission is probably high between the many visitors, but the issue has been infrequently studied. OBJECTIVES: Investigate microorganism variety and risk of contamination on commonly used carpets and rosaries (prayer beads). DESIGN: Cross-sectional. SETTINGS: Mosques. METHODS: This study was carried out in three different cities of Turkey in 2023, focusing on mosques located around hospitals. Forty mosques were included in the study and from each mosque 10 samples were collected from various parts of carpets and rosaries. The number of positive culture isolates were identified. MAIN OUTCOME MEASURES: Diversity and distribution of microorganisms isolated from mosque carpets and rosaries; methicillin-resistance rates in Staphylococci. SAMPLE SIZE: 400 samples. RESULTS: Growth was observed in 368 (92%) of 400 samples examined. The microorganisms isolated in the highest number were methicillin-susceptible coagulase negative Staphylococci (MSCoNS) (59.8%), Microcooccus (41%) and diphtheroids (31.3%). The rates of total growth (P=.001), including diphtheroids (P=.018), methicillin-resistant coagulase negative Staphylococci (P=.001), Bacillus spp. (P=.036) and Aspergillus spp. (P=.002) rates were significantly higher in the rosary samples than carpet samples. At mosques in Tokat, a province center, 4 samples were positive for Acinetobacter baumannii, two samples were positive for Pseudomonas aeruginosa and one sample for methicillin-resistant Staphylococcus aureus (MRSA), and these were isolated from rosaries. 0.3% of Staphylococcus isolates were MRSA. CONCLUSION: As there is a high risk of contamination of carpets and prayer beads on the mosque floor with human flora, the use of appropriate hygiene practices is necessary. We also found some emerging bacteria in addition to the normal human flora. LIMITATIONS: Our study was conducted in three provinces. Further studies might cover a wider geography.

The interplay between parental behaviors and adolescents' sports-related values in understanding adolescents' dropout of organized sports activities.

Using short-term longitudinal data, the primary goal of the present study was to examine the interplay between adolescents' sports-related intrapersonal (e.g., sports values) and interpersonal factors (e.g., perceived parental involvement) in relation to sports dropout. A secondary goal was to explore the direction of effects in the association between intra- and interpersonal factors. A total of 420 adolescents (39% girls, Mage = 14.06; SDage = 0.33) responded to a set of survey questions over two consecutive years. Results from structural equation modeling suggested that parental involvement predicted adolescents' dropout one year later, via sports values. Further, the results suggested that the direction of influence is mainly from parents to adolescents. Overall, the findings indicate that adolescents whose parents attend their practices and games perceive sports activities as fun, important and useful; as a result, adolescents are less likely to dropout. The findings offer an improved understanding of how parents' behaviors may influence adolescents' dropout of organized sports.

Defective COX1 expression in aging mice liver.

Mitochondrial defects are associated with aging processes and age-related diseases, including cardiovascular diseases, neurodegenerative diseases and cancer. In addition, some recent studies suggest mild mitochondrial dysfunctions appear to be associated with longer lifespans. In this context, liver tissue is considered to be largely resilient to aging and mitochondrial dysfunction. Yet, in recent years studies report dysregulation of mitochondrial function and nutrient sensing pathways in ageing livers. Therefore, we analyzed the effects of the aging process on mitochondrial gene expression in liver using wildtype C57BL/6N mice. In our analyses, we observed alteration in mitochondrial energy metabolism with age. To assess if defects in mitochondrial gene expression are linked to this decline, we applied a Nanopore sequencing based approach for mitochondrial transcriptomics. Our analyses show that a decrease of the Cox1 transcript correlates with reduced respiratory complex IV activity in older mice livers.

Ultrasonographically detected hepatosteatosis independently predicts the presence and severity of coronary artery disease.

Background: Nonalcoholic fatty liver disease (NAFLD) has shown to be associated with coronary artery disease (CAD). Objectives: The aim of our study was to evaluate the association between the presence and severity of CAD and NAFLD. Methods: The study group consisted of 153 patients who underwent coronary angiographies. Patients were categorized into CAD and non-CAD groups. CAD severity was determined by the number of CAD-involved arteries and the vessel score multiplied by Gensini score, the latter judging CAD severity. Fatty liver was diagnosed by abdominal ultrasonography (USG), with the patients being categorized by the degree of hepatosteatosis, as Grade 0, Grade 1, and Grade 2-3. Results: Among the whole study population, 47.1% of patients (n=72) were female and 52.9% of patients (n=81) were male. Forty-three patients had normal coronary arteries; 27 patients had non-critical CAD and side branch disease; and 83 patients had clinically significant CAD (stenosis>50%). The rate of CAD and Gensini score were significantly different between Grade 0, 1 and 2-3 hepatosteatosis groups (p<0.05). Patients with CAD had a significantly higher AST level than those without (p< 0.05). Conclusions: Ultrasonographically detected hepatosteatosis independently predicts the presence and severity of CAD.

Bystanders of ethnic victimization: Do classroom context and teachers' approach matter for how adolescents intend to act?

The study examined how adolescents' individual characteristics and class context are related to bystander behaviors in cases of ethnic victimization. The sample included 1065 adolescents in Sweden (Mage  = 13.12, SD = 0.42; 55%males). Female adolescents, adolescents of immigrant background, and adolescents with positive attitudes toward immigrants had greater intentions to defend and comfort victimized peers. Positive inter-ethnic contact norms in class were positively associated with intention to comfort the victim. Teachers' non-tolerance of ethnic victimization was positively related to adolescents' intentions to ask the perpetrator to stop and talk to teacher. The effects were the same across adolescents with different attitudes toward immigrants. Findings highlight the importance of class context and teachers in fostering adolescents' prosocial and assertive interventions in bias-based hostile behaviors.

Trajectories of insomnia symptoms and insufficient sleep duration in early adolescents: associations with school stress.

Study Objectives: We examined how adolescents' sleep patterns (i.e. insomnia symptoms and sleep duration) change from early- to mid-adolescence and whether adolescents follow different trajectories. Furthermore, we also examined the characteristics of adolescents within different trajectories, with a specific focus on the role of school-related stress. Methods: We used three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1294; Mage = 13.2 [range: 12-15 years], SD = .42; 46.8% girls). Using established measures, the students reported on their sleep duration, insomnia symptoms, and perceived school-stress (including stress of school performance, peer and teacher relations, attendance, and school-leisure conflict). We used latent class growth analysis (LCGA) to identify adolescents' sleep trajectories, and the BCH method to describe the characteristics of the adolescents in each trajectory. Results: We found four trajectories for adolescents' insomnia symptoms; (1) low insomnia (69%), (2) low-increasing (17%, 'emerging risk-group'), (3) high-decreasing (9%), (4) high-increasing (5%; 'risk-group'). For sleep duration, we found two trajectories; (1) ~8 h sufficient-decreasing (85%), (2) ~7 h insufficient- decreasing (15%; 'risk-group'). Adolescents in risk-trajectories were more likely to be girls and consistently reported higher levels of school stress, particularly regarding school performance and attending school. Conclusions: School stress was prominent among adolescents suffering from persistent sleep problems, especially insomnia, and deserves further attention.

Immigrant and Swedish adolescents' involvement in organized sports activities: an expectancy-value approach.

BACKGROUND: Drawing on Eccles' expectancy-value model, we investigated the associations between parents' sports-related socialization behaviors in the family context, youth's sports' values, and youth's involvement in organized sports activities in the Nordic countries. More specifically, we tested the mediating effect of youth's sports' values on the link between socialization of sports in the family setting and youth's sports participation. Further, we examined whether any associations were moderated by youth's immigrant background or gender. METHODS: Immigrant and Nordic adolescents (N = 678), in 7th-8th grade, were followed over two consecutive years and responded to surveys during regular class hours. RESULTS: Supporting Eccles' model, we found that sports-related family co-activities significantly predicted youth's prospective sports-related behaviors through youth's sports' values. The mediation process was robust across both Nordic and immigrant youth and adolescent girls and boys. Further, our results revealed that parents' role modeling of sports activities was linked to both the amount of time youth currently spend on sports and their continuation in sports through youth's sports' values, although these associations were only significant for immigrant youth. CONCLUSIONS: Our findings offer insights into how participation in organized sports activities can be promoted among both immigrant and Nordic youth and among boys and girls. Most importantly, the findings may have valuable implications for researchers, policymakers and practitioners interested in promoting youth's involvement in organized sports activities. This especially applies to immigrant youth, given that the literature consistently reports lower sports involvement among immigrant youth than their native counterparts.

Role of Point-of-Care Lung and Inferior Vena Cava Ultrasound in Clinical Decisions for Patients Presenting to the Emergency Department With Symptoms of Acute Decompensated Heart Failure.

OBJECTIVES: This prospective study was performed to evaluate the diagnostic role of point-of-care lung ultrasound (LUS) and inferior vena cava (IVC) ultrasound in patients with acute decompensated heart failure (ADHF). METHODS: A prospective cohort study was conducted between January 2018 and November 2018 on patients with a diagnosis of ADHF in the emergency department (ED). On admission, LUS findings, inspiratory and expiratory IVC diameters, and the inferior vena cava collapsibility index (IVCCI) were obtained. After therapeutic interventions, third-hour changes in LUS and the IVC index and the treatment response were assessed. RESULTS: Eighty patients were enrolled. Forty-six (58%) patients had an ejection fraction (EF) greater than 40%, and 34 (42%) had an EF of less than 40%. Significant differences were detected between the admission and third-hour inspiratory IVC diameter, expiratory IVC diameter, and IVCCI (P = .001). There was no correlation between the EF and inspiratory IVC diameter (r = -0.03; P = .976), expiratory IVC diameter (r = -109; P = .336), or IVCCI (r = -0.72; P = .523) and between the B-type natriuretic peptide level and inspiratory IVC diameter (r = -0.58; P = .610), expiratory IVC diameter (r = -0.33; P = .774), or IVCCI (r = -0.78; P = .493) either. A comparison of admission and third-hour numbers of B-lines on LUS imaging showed a significant decrease in the number of B-lines in all zones at the end of 3 hours (P = .001). A significant difference existed between the hospitalized and discharged patients with respect to IVC diameters and number of B-lines. CONCLUSIONS: In the ED setting, an assessment of B-lines and measurement of IVC diameters are better markers than the B-type natriuretic peptide level, EF, or chest x-ray for diagnosis of ADHF and can be used to make decisions for hospitalization or discharge from the ED.

How Does Adolescents' Openness to Diversity Change Over Time? The Role of Majority-Minority Friendship, Friends' Views, and Classroom Social Context.

Young people are growing up in increasingly "super-diverse" societies, and show variations in how they approach diversity and embrace differences. Developing a good understanding of why some youth appreciate and value diversity whereas others do not is crucial in identifying ways to promote social interactions among different groups in broader society. The current study examined whether adolescents follow different trajectories in their views on diversity, and identified possible factors behind how they change over time. The sample included 1362 adolescents residing in Sweden (Mage = 13.18, SD = 0.43, 48% girls). Adolescents reported on their openness to diversity and classroom social climate. The peer nominations method was used to measure majority-minority friendship, and friends' views on diversity. Latent growth analysis showed that adolescents, on average, became more open to diversity over time, but with clear heterogeneity. Three distinct trajectories were identified as: high-increasing, average-increasing, and average-declining. Relative to the high-increasing group, the other two were more likely to be male and immigrant. Relative to the high-increasing group, adolescents on the average-increasing trajectory perceived their classroom climate as less cooperative, while the adolescents on the average-declining trajectory were less likely to have friends with positive views on diversity. The findings suggest that schools may serve as a shared ground for promoting openness to diversity.

Differences and Similarities between Perpetrators of Ethnic and Non-Ethnicity-Based Victimization.

Immigrant and minority youth are at risk of ethnic victimization. Despite an increasing number of studies that aim to understand the consequences of such negativity, relatively little attention has been paid to understanding who the perpetrators of ethnic victimization are. To address this gap in knowledge, the present study examined whether youth who victimize their peers due to their ethnic background are also those who engage in non-ethnicity-based victimization. The study also investigated the underlying factors, i.e., impulsivity, empathy, moral disengagement, and attitudes toward immigrants, that are common or specific to groups of youth. The sample included 949 adolescents residing in Sweden (Mage = 13.11, SD = 0.41; range: 12-15; 46% girls). Cluster analysis revealed four distinct groups of adolescents, based on their reports of ethnic and non-ethnicity-based victimization: (1) low on both forms of victimization, (2) high on ethnic victimization only, (3) high on non-ethnicity-based victimization only, and (4) high on both forms of victimization. The results showed that being morally disengaged is a common denominator of ethnic and non-ethnicity-based victimizers. Difficulties in regulating impulses and lack of perspective-taking skills trigger youth's engagement in non-ethnicity-based victimization. Lack of empathic concerns and low levels of positive attitudes toward immigrants are the bases of ethnic victimization. Together, these findings suggest that the precursors of ethnic and non-ethnicity-based victimization have similarities as well as differences, which require further attention in developing programs aimed at preventing different forms of peer victimization.

The Role of Perceived Inter-Ethnic Classroom Climate in Adolescents' Engagement in Ethnic Victimization: For Whom Does it Work?

Immigrant and minority youth are at risk of experiencing victimization due to their ethnic, cultural, or religious background. Despite an increasing number of studies that aims at understanding the consequences of being the target of such negative experiences, little attention has been paid to the factors that might counteract the occurrence of ethnic victimization. The present study aimed to address this gap in knowledge by investigating the possible role of school context. Specifically, the present study examined the extent to which perceived positive contact norms in class and teachers' reactions to ethnic victimization are linked to engagement in ethnic victimization. It also examined whether such links differ across adolescents with different levels of tolerance toward immigrants. The sample included 963 adolescents residing in Sweden (Mage = 13.11, SD = 0.41; 46% girls). The results showed that perceived positive contact norms in class were associated with a lower likelihood of engagement in ethnic victimization across youth with different levels of tolerance toward immigrants. When adolescents perceived their teachers as not tolerating ethnic victimization, those with high levels of tolerance were less likely to engage in it. However, teacher reactions did not affect the behaviors of adolescents with low and moderate levels of tolerance toward immigrants. The findings indicate the importance of classroom context and teachers in counteracting negative interactions among students of diverse backgrounds.

Prisoners seeking healthcare in emergency department.

OBJECTIVE: To evaluate inmate referrals to emergency department of a tertiary healthcare facility in terms of demographical and clinical characteristics as well as their impact on the department. METHODS: The retrospective cross-sectional study was conducted at Ankara Numune Training and Research Hospital, Ankara, Turkey and comprised data of incarcerated patients who were brought to the emergency department from January 01, 2010, to December 31, 2012. Demographical characteristics, consultations, duration of hospitalisation, recurrent admissions, disposal and mortality rates were noted. The referrals were grouped as surgical conditions, medical disorders, Eye, Ear, Nose, Throat problems, injury and psychiatric disorders. The groups were then subdivided according to diagnosis. SPSS 22 was used for data analysis. RESULTS: Of the 856 patients, 804(93.4%) were men and 52(6.1%) were women. The overall mean age was 37.54±14.81 years (range: 15-83 years). The number of patients was the highest in the medical group 363(42.4%) and the lowest in the Eye, Ear, Nose, Throat group 56(6.5%). Mean age of the surgical group was significantly lower than the medical group (p<0.001) but significantly higher than that of the trauma group (p=0.001). CONCLUSIONS: Functional emergency response units, strict emergency triage of inmates and their rapid care and management in jails can help avoid referring these patients to already overcrowded emergency departments.

How do Adolescents' Perceptions of Relationships with Teachers Change during Upper-Secondary School Years?

The student-teacher relationship has mostly been assumed to be static. This approach is limited in providing information on how relationships with teachers evolve over time, and how possible changes affect young people's adjustment. To address this gap in knowledge, the present study examined whether adolescents follow different trajectories in their perceptions of relationship with teachers and whether students on different trajectories differ from each other in their adjustment. The sample included 829 students residing in Sweden (Mage = 13.43, SD = 0.55, 51% girls). Three distinct teacher-relationship trajectories were identified. More than half (66%) of the adolescents (average-stable trajectory) reported an average level of positive relationships with teachers at grade 7, and did not change significantly over the three years. About 24% of the adolescents (high-increasing trajectory) reported a high level of fair and supportive teacher-relationships at T1, and continued to increase in their positive views from grade 7 to grade 9. Ten percent of the adolescents (average-declining trajectory) reported an average level of positive relationships with teachers at grade 7, but showed a decline in their positive views towards teachers over time. Relative to adolescents on an average-stable trajectory, adolescents on a high-increasing trajectory reported greater school satisfaction, higher achievement values, and lower failure anticipation. By contrast, adolescents in the average-declining group reported worsening school adjustment. No significant moderating effects of immigrant status and gender were found. These findings highlight the importance of the association between the continuous experience of supportive and fair teacher treatment and youth adjustment.

Is Bedside End-Tidal CO2 Measurement a Screening Tool to Exclude Pulmonary Embolism in Emergency Department?

BACKGROUND: Pulmonary embolism (PE) is among the most difficult conditions to diagnose in emergency department. The majority of patients thought to have PE are tested positive for D-dimer and subsequently tested with advanced diagnostic modalities. Novel noninvasive tests capable of excluding PE may obviate the need for advanced imaging tests. We studied the role of combined clinical probability assessment and end-tidal carbon dioxide (ETCO2) measurement for diagnosis of possible PE in emergency department. METHODS: We included 100 consecutive subjects suspected to have PE and a positive D-dimer test to study clinical probability of PE and ETCO2 levels. ETCO2 > 34 mm Hg was found to be the best cut-off point for diagnosing PE. PE was ultimately eliminated or diagnosed by spiral computed tomography (CT). RESULTS: Diagnostic performances of tests were as follows: ETCO2 and D-dimer had a sensitivity of 100% and a negative predictive value (NPV) of 100% at the cut-off levels of 34 mm Hg and 500 ng/mL, respectively; Wells score had a sensitivity of 80% and NPV of 69.7% at a score of 4. CONCLUSIONS: ETCO2 alone cannot reliably exclude PE. Combining it with clinical probability, however, reliably and correctly eliminates or diagnoses PE and prevents further testing to be done.

Ethnic Harassment and Immigrant Youth's Engagement in Violent Behaviors: Understanding the Risk Factors.

The present study aimed to examine whether ethnic harassment was related to violent behaviors among immigrant youth over time and to identify the risk factors. The sample comprised immigrant adolescents living in Sweden (N = 365; Mage  = 13.93, SD = 0.80). Results showed that the more youth were ethnically harassed, the more they engaged in violent acts over time. A separated identity significantly moderated the effect of ethnic harassment on youth's engagement in violent behaviors. Specifically, ethnic harassment positively predicted engagement in violent behaviors only at high levels of separated identity. Impulsivity and school ethnic composition did not act as moderators. The findings suggest that preventing violent behaviors among immigrant youth requires a focus on promoting positive interethnic relationships, and multicultural identity among immigrant youth.

Plasma Chemerin Levels Are Increased in ST Elevation Myocardial Infarction Patients with High Thrombus Burden.

OBJECTIVE: To investigate plasma chemerin levels in ST elevation myocardial infarction (STEMI) patients and find out possible relationships between plasma chemerin levels and angiographic characteristics. PATIENTS AND METHODS: Ninety-seven consecutive patients who presented with STEMI and underwent primary percutaneous coronary intervention (PCI) with coronary stents were enrolled, and 30 age- and sex-matched patients with stable angina pectoris who underwent coronary angiography formed the control group. Angiographic characteristics of the patients including thrombolysis in myocardial infarction (TIMI) thrombus and Gensini scores were noted. Blood samples were taken to detect several biochemical markers including plasma chemerin levels at the admission to hospital. RESULTS: Serum chemerin and C-reactive protein (CRP) levels were significantly increased in patients with STEMI. Among STEMI patients, serum chemerin levels were significantly higher in patients with high thrombus burden (581.5 ± 173.7 versus 451.3 ± 101.2 mg/dL, p < 0.001). CRP levels and peak creatine kinase-MB (CK-MB) levels were higher, and left ventricular ejection fraction and post-PCI TIMI flow were lower in patients with high thrombus burden. After multivariate analysis, serum chemerin levels were also higher in patients with high thrombus grade (odds ratio: 1.009 (1.005-1.014), p < 0.001). Besides, serum chemerin levels were also found to be significantly correlated with CRP (r=0.47, p < 0.001) and peak CK-MB (r=0.376, p < 0.001) levels. CONCLUSIONS: Results from our study have demonstrated for the first time that chemerin levels were higher in STEMI patients with greater thrombus burden and higher level of inflammation.

Adolescents' Engagement in Ethnic Harassment: Prejudiced Beliefs in Social Networks and Classroom Ethnic Diversity.

Research on ethnic victimization to date has done little to identify the reasons why adolescents victimize their peers due to their ethnic background. To address this limitation, we examined: (1) the extent to which prejudiced attitudes within adolescents' close and larger social networks determine their engagement in ethnic harassment, and (2) the extent to which classroom ethnic diversity plays a role in any such link. Our sample included 902 Swedish adolescents (M age = 14.40, SD = .95; 50.3% girls). We found that Swedish adolescents who held negative attitudes toward immigrants or who were surrounded by prejudiced peers were more likely to be involved in ethnic harassment, particularly in classrooms with high ethnic diversity. Adolescents in classrooms with a high anti-immigrant climate were more likely to harass their immigrant peers. These findings suggest that prejudiced beliefs in youth social networks put young people at risk of engaging in ethnic harassment, particularly in ethnically diverse classrooms.

Is the use of headless compression screws appropriate in arthroscopic ankle arthrodesis?

OBJECTIVES: This study aims to evaluate whether the use of headless compression screws is appropriate in arthroscopic ankle arthrodesis. PATIENTS AND METHODS: Twenty-two feet of 22 patients (12 males, 10 females; mean age 43.7 years; range 21 to 63 years) in whom we applied arthroscopic ankle arthrodesis were examined retrospectively. Mean follow-up duration was 59.3 months (range 36 to 92 months). Coronal and sagittal plane alignment and concomitant pathologies were evaluated on patients' radiographs. Assessments related to pain and functionality were performed by the American Orthopaedic Foot and Ankle Society (AOFAS) scoring. RESULTS: Radiographic union was achieved in 21 of the total 22 ankles (95.4%). Mean time to union was 10.3±3.5 weeks (range 6.6 to 13.8 weeks). Mean AOFAS pain score increased from 8.1±10.2 to 35.0±6.3 and functional score increased from 21.3±5.5 to 43.4±3.8 (p<0.001). On coronal plane, preoperative tibiotalar angle of 6.6±5.5° decreased to 2.3±2.1° postoperatively. On sagittal plane, while preoperative tibiotalar angle was 17±4.9°, it was 17±4.5° postoperatively. One patient had subtalar pain and one patient had nonunion postoperatively. CONCLUSION: The use of headless compression screws is an appropriate choice in the ankle area owing to their advantages of providing successful fixation whilst not causing screw head irritation or pain.

Two-Year Findings from a National Effectiveness Trial: Effectiveness of Behavioral and Non-Behavioral Parenting Programs.

Long-term follow-up studies of selective parent training (PT) programs are scarce, particularly in the case of effectiveness trials conducted within regular care settings. This study evaluated the 2-year effects of 4 programs: Comet, Incredible Years, Cope, and Connect and differences in the rate of change among programs were investigated using Latent Growth Modeling (LGM). Participants were parents who had sought help at 30 local service sector units (e.g., child psychiatric clinics and social services centers) for major problems in managing their children's externalizing behavior. Parents of 749 children (63 % boys) with moderate levels of externalizing behavior, aged 3-12, were randomized to one of the 4 PT programs. Assessments included parent-reported measures of child externalizing, hyperactivity and inattention, as well as parenting practices, sense of competence, and parents' stress and depressive symptoms. At 2-year follow-up, there were no differences in any of the child outcomes among the programs. All programs had reduced externalizing behaviors with large effect sizes (d = 1.21 to d = 1.32), and negative parenting practices with moderate to large effect sizes (d = 0.49 to d = 0.83). LGM analyses showed that the 2 behavioral programs, Comet and Incredible Years, produced more rapid reductions in externalizing behavior during the course of the intervention than the non-behavioral program, Connect. Connect, however, was the only program where children continued to improve after the intervention. Overall, the results indicate that the 4 programs were equally effective in a clinical setting, despite differences in their theoretical origin.
