Are Nonfatal Suicide Attempts Instrumental in Achieving Personal and Interpersonal Goals?

This study focused on the well-being of the survivors of suicide attempts and the well-being of their interpersonal relationships after the attempt. The data came from a sample of 392 college students from 10 Muslim majority countries who reported having attempted suicide in the last 4 years. Suicide was conceptualized as a goal-directed behavior embedded in a sociocultural context and motivated by personal or interpersonal goals. We tested a process that linked culturally shaped self-construal to the postsuicidal personal and interpersonal well-being. We posited that this process would operate through the attitudes towards suicide, motives for suicide, the strength of the intention to die. Our model indicated that the acceptability of suicide was positively associated with escape motives, and this association was even stronger for the individuals with interdependent self-construals. Escape motives were negatively associated with postsuicidal personal and interpersonal well-being, but communication motives were not associated with these outcomes. We also found evidence that having an interdependent self-construal might be beneficial for postsuicidal personal and interpersonal well-being. Our results further suggested that the postsuicidal personal and interpersonal well-being of highly interdependent individuals may depend on the interpretation of their act of suicide by their close others.

Trichloroethylene increases pulmonary endothelial permeability: implication for pulmonary veno-occlusive disease.

Trichloroethylene exposure is a major risk factor for pulmonary veno-occlusive disease. We demonstrated that trichloroethylene alters the endothelial barrier integrity, at least in part, through vascular endothelial (VE)-Cadherin internalisation, and suggested that this mechanism may play a role in the development of pulmonary veno-occlusive disease.

On the Road to Social Death: A Grounded Theory Study of the Emotional and Social Effects of Honor Killing on Families-A Palestinian Perspective.

Despite high rates of domestic violence and increased rates of honor killing (HK) over the past decade, there is a paucity of empirical data about how HK affects family members. This study used grounded theory to explore the emotional and social effects of HK on 23 family members of murdered women and found that HK failed to achieve the restoration of honor. Following HK, families subsequently entered a protracted process of grief compounded by negative social interactions, which led to a form of "social death." The road to social death was a painful and continuous social process, which, for many, never abated.

Self-Perceived Health Status and Sense of Coherence in Children With Type 1 Diabetes in the West Bank, Palestine.

Introduction: Self-perceived health status and sense of coherence (SOC) are essential constructs for capturing health outcomes in children with type 1 diabetes (T1D). This study measured self-perceived health status and SOC in children with T1D and compared them with a healthy reference group in West Bank, Palestine. Methodology: One hundred children with T1D aged 8 to 18 years and 300 healthy children completed PedsQL 4.0 Generic Core Scales and SOC-13 in a cross-sectional descriptive study. Results: All children reported acceptable self-perceived health status and low degree of SOC. In the diabetes group, high degree of SOC was associated with better self-perceived health status and more optimal metabolic control. Males in the diabetes group reported higher self-perceived health status than females. Discussion: The unstable political situation in Palestine may threaten SOC in children in general. Health professionals can monitor self-perceived health status and SOC to evaluate interventions aiming to improve glycemic control.

Suicidal Thoughts, Attempts and Motives Among University Students in 12 Muslim-Majority Countries.

There is a scarcity of research on suicidal phenomena in the Muslim world. Therefore, this study aimed at investigating the self-reported prevalence of suicidal thoughts, attempts and motives in 12 Muslim countries. A total of 8417 (54.4% women) university students were surveyed by means of a self-report questionnaire. Overall, 22% of the participants reported suicidal ideation and 8.6% reported attempting suicide. The odds of suicidal thoughts were elevated in Azerbaijan, Indonesia and Saudi Arabia, while reduced ORs were recorded in Egypt, Jordan, Lebanon and Malaysia. While odds of suicide attempts were high in Azerbaijan, Palestine and Saudi Arabia reduced odds ratios (OR) were detected in Indonesia, Iran, Jordan, Lebanon, Malaysia and Tunisia. Taking drugs and using a sharp instrument were the two most frequently used methods to attempt suicide. Only 32.7% of attempts required medical attention. Escape motives were endorsed more than social motives by participants who attempted suicide. Suicidal behaviors were more frequent in women than in men. Compered to men, fewer attempts by women required medical attention. Moreover, our results show that making suicide illegal does not reduce the frequency of suicidal behavior. Results from this comparative study show that suicidal thoughts and attempts are frequent events in young adults in countries where religious scripture explicitly prohibit suicide and the frequencies of nonfatal suicidal behavior show large variation in nations adhering to the same religion.

Associations of diet and lifestyle factors with common volatile organic compounds in exhaled breath of average-risk individuals.

BACKGROUND: Detection of diseases via exhaled breath remains an attractive idea despite persisting gaps in understanding the origin of volatile organic compounds (VOCs) and their relationship with the disease of interest. Data on factors potentially influencing the results of breath analysis remain rather sparse and often controversial. In this study, we aimed to investigate the associations of common VOCs in exhaled breath of average-risk individuals with socio-demographic and lifestyle factors, medical conditions as well as diet. METHODS: Alveolar breath samples of 1447 men and women were collected in the morning after fasting and were analyzed using gas-chromatography linked with mass-spectrometry. Study participants were 40-64 years old, cancer-free, with overall good health status. The associations between selected VOCs and various factors determined from the questionnaire data were assessed using two-part-Wilcoxon test and Jonckheere-Terpstra trend test. RESULTS: Fifteen VOCs where each of them was detected in at least 80% of the study population were included in this analysis. Statistically significant associations with various VOCs were demonstrated for gender and consumption of certain foods, such as coffee, leeks and garlic, while smoking was not associated with any of the analyzed compounds. CONCLUSION: Factors potentially modifying the composition of exhaled breath, such as dietary factors, deserve careful attention in the design and analysis of studies accessing the use of VOCs as diagnostic markers.

Struggling and Overcoming Daily Life Barriers Among Children With Congenital Heart Disease and Their Parents in the West Bank, Palestine.

Advances in early diagnosis, treatment, and postoperative care have resulted in increased survival rates among children with congenital heart disease (CHD). Research focus has shifted from survival to long-term follow-up, well-being, daily life experiences, and psychosocial consequences. This study explored the everyday experiences of children with CHD and of their parents living in the Palestinian West Bank. Interviews with nine children aged 8 to 18 years with CHD and nine parents were analyzed using content analysis. The overall theme that emerged was facing and managing challenges, consisting of four themes: sociocultural burden and finding comfort, physical and external limitations, self-perception and concerns about not standing out, and limitations in access to health care due to the political situation. To provide optimum care for children with CHD and their parents, health care providers and policy makers must understand the negative consequences associated with sociocultural conditions and beliefs about chronic illness.

Societal Norms and Conditions and Their Influence on Daily Life in Children With Type 1 Diabetes in the West Bank in Palestine.

PURPOSE: To explore the experiences of daily life in children with type 1 diabetes (T1D) and their parents living in the West Bank in Palestine. DESIGN AND METHODS: A qualitative study using thematic interviews was performed with 10 children with T1D and their parents (n=10). Content analysis was performed with the assistance of NVIVO 10. RESULTS: The overall theme was facing the social reality of diabetes. This was underpinned by two themes: stigmatization and social constraints. Facing the social reality of diabetes described children and their parents' everyday life attempts to place themselves within the context of the disease and social context. Children and their parents described how stigmatization and social constraints impacted their daily life as a result of fear of disclosing the disease, which could affect their social status. CONCLUSION: These findings highlighted how daily life in children with T1D and their parents was highly affected by cultural impacts, especially as stigma related to the illness affected social interactions of female and male children/adolescents. Lack of knowledge and misunderstandings about T1D in society lead to negative consequences like poorer management of diabetes, and this becomes mediated by gender. PRACTICAL IMPLICATIONS: The findings suggest health care providers need to be aware of the cultural and social impact of T1D on children's and parents' daily life in order to meet their needs and challenges by providing appropriate interventions, strategies and support.

Diagnosis and Classification of 17 Diseases from 1404 Subjects via Pattern Analysis of Exhaled Molecules.

We report on an artificially intelligent nanoarray based on molecularly modified gold nanoparticles and a random network of single-walled carbon nanotubes for noninvasive diagnosis and classification of a number of diseases from exhaled breath. The performance of this artificially intelligent nanoarray was clinically assessed on breath samples collected from 1404 subjects having one of 17 different disease conditions included in the study or having no evidence of any disease (healthy controls). Blind experiments showed that 86% accuracy could be achieved with the artificially intelligent nanoarray, allowing both detection and discrimination between the different disease conditions examined. Analysis of the artificially intelligent nanoarray also showed that each disease has its own unique breathprint, and that the presence of one disease would not screen out others. Cluster analysis showed a reasonable classification power of diseases from the same categories. The effect of confounding clinical and environmental factors on the performance of the nanoarray did not significantly alter the obtained results. The diagnosis and classification power of the nanoarray was also validated by an independent analytical technique, i.e., gas chromatography linked with mass spectrometry. This analysis found that 13 exhaled chemical species, called volatile organic compounds, are associated with certain diseases, and the composition of this assembly of volatile organic compounds differs from one disease to another. Overall, these findings could contribute to one of the most important criteria for successful health intervention in the modern era, viz. easy-to-use, inexpensive (affordable), and miniaturized tools that could also be used for personalized screening, diagnosis, and follow-up of a number of diseases, which can clearly be extended by further development.

Analysis of the effects of microbiome-related confounding factors on the reproducibility of the volatolomic test.

Volatile organic compound (VOC) testing in breath has potential in gastric cancer (GC) detection. Our objective was to assess the reproducibility of VOCs in GC, and the effects of conditions modifying gut microbiome on the test results. Ten patients with GC were sampled for VOC over three consecutive days; 17 patients were sampled before and after H. pylori eradication therapy combined with a yeast probiotic; 61 patients were sampled before and after bowel cleansing (interventions affecting the microbiome). The samples were analyzed by: (1) gas chromatography linked to mass spectrometry (GC-MS), applying the non-parametric Wilcoxon test (level of significance p < 0.05); (2) by cross-reactive nanoarrays combined with pattern recognition. Discriminant function analysis (DFA) was used to build the classification models; and leave-one-out cross-validation analysis was used to classify the findings. Exhaled VOCs profiles were stable for GC patients over a three day period. Alpha pinene (p = 0.028) and ethyl acetate (p = 0.030) increased after the antibiotic containing eradication regimen; acetone (p = 0.0001) increased following bowel cleansing prior to colonoscopy. We further hypothesize that S. boulardii given with the standard eradication regimen to re-establish the gut microbiome was the source for long-term ethyl acetate production. Differences between the initial and the follow-up sample were also revealed in the DFA analysis of the sensor data. VOC measurement results are well-reproducible in GC patients indicating a useful basis for potential disease diagnostics. However, interventions with a potential effect on the gut microbiome may have an effect upon the VOC results, and therefore should be considered for diagnostic accuracy.

Application of Organophosphonic Acids by One-Step Supercritical CO2 on 1D and 2D Semiconductors: Toward Enhanced Electrical and Sensing Performances.

Formation of dense monolayers with proven atmospheric stability using simple fabrication conditions remains a major challenge for potential applications such as (bio)sensors, solar cells, surfaces for growth of biological cells, and molecular, organic, and plastic electronics. Here, we demonstrate a single-step modification of organophosphonic acids (OPA) on 1D and 2D structures using supercritical carbon dioxide (SCCO2) as a processing medium, with high stability and significantly shorter processing times than those obtained by the conventional physisorption-chemisorption method (2.5 h vs 48-60 h).The advantages of this approach in terms of stability and atmospheric resistivity are demonstrated on various 2D materials, such as indium-tin-oxide (ITO) and 2D Si surfaces. The advantage of the reported approach on electronic and sensing devices is demonstrated by Si nanowire field effect transistors (SiNW FETs), which have shown a few orders of magnitude higher electrical and sensing performances, compared with devices obtained by conventional approaches. The compatibility of the reported approach with various materials and its simple implementation with a single reactor makes it easily scalable for various applications.
