Revisiting suicide rate during wartime: Evidence from the Sri Lankan civil war.

ABSTRACT: After the seminal work of Durkheim (1897), many subsequent studies have revealed a decline in suicide rates during wartime. However, their main focus was inter-state wars and whether the same argument holds for civil conflicts within a country is an important unresolved issue in the modern world. Moreover, the findings of the previous studies are not conclusive due to unobserved confounding factors. This study investigated the relationship between civil war and suicide rate through a more rigorous statistical approach using the Sri Lankan civil war as a case study. For this purpose, we employed a linear regression model with district and year fixed effects to estimate a difference-in-difference in the suicide rate between the peacetime and wartime periods as well as the contested and non-contested districts. The results indicate that the suicide rate in the contested districts in the wartime was significantly lower than the baseline by 11.8-14.4 points (95% CI 6.46-17.22 and 7.21-21.54, respectively), which corresponds to a 43-52% decline. The robustness of the possible confounding factors was analyzed and not noted to have so much effect as to alter the interpretation of the results. This finding supports the Durkheimian theory, which places importance on social integration as a determinant of suicide, even for civil conflicts.

Project description:BackgroundPoor compliance with hand hygiene practices among medical students poses a risk for cross-infection. It has become more critical during the COVID-19 pandemic than ever before. This study aimed to determine the knowledge, attitudes, practices of hand hygiene among final-year medical students. It also explored reported hand hygiene behavior before the COVID-19 pandemic and the need for educational strategies to correct the deficiencies.MethodsA concurrent mixed-method approach was used. In the quantitative strand, a cross-sectional online survey was carried out via a Google form. Mann-Whitney U test and Chi-squared test were used for comparisons. In the qualitative strand, twelve participants were interviewed, based on a semi-structured interview guide and audio recorded. Transcribed data were evaluated with thematic content analysis.ResultsA total of 225 final-year medical students were studied in the quantitative strand. Most were females. The mean score for knowledge was 3.35 ± 0.795 out of six. Of them, 31.6 % of participants scored below 3 points (< 50 % of the total). Most (78.9 %) had positive attitudes (score of > 80 %). Only 36.4 % reported "adequate" hand hygiene performance in all eight dimensions of the behavior domain. Noticeably, fewer participants reported to clean their hands after checking blood pressure (55.6 %), and only 66.2 % stated carrying a hand sanitizer in their pocket. Significant correlations were not found between reported behavior and attitudes (p = 0.821) or knowledge (p = 0.794). The qualitative strand with 12 respondents revealed the positive influence of both hierarchical and non-hierarchal role models. Time constraints, skin irritation, and workload pressures were the main barriers. Frequent reminders, supervision, and interactive teaching were suggested as methods to improve hand hygiene compliance. They also stated that increased enthusiasm was noted on hand hygiene during the COVID-19 pandemic compared to the pre-pandemic period.ConclusionsMost of the participants had positive attitudes towards hand hygiene. Yet, a considerable gap between attitudes and knowledge and reported hand hygiene behavior was evident. Coupling educational programs that use cognitive and behavioral methods, including role modeling, supervision, and frequent reminders, is recommended to bridge the knowledge-attitude-behavior gap.

Project description:BackgroundScientific research is an essential component in guiding improvements in health systems. There are no studies examining the Sri Lankan medical research output at international level. The present study evaluated the Sri Lankan research performance in medicine as reflected by the research publications output between years 2000-2009.MethodsThis study was based on Sri Lankan medical research publication data, retrieved from the SciVerse Scopus® from January 2000 to December 2009. The process of article selection was as follows: Affiliation - 'Sri Lanka' or 'Ceylon', Publication year - 'January 2000 to December 2009' and Subject area - 'Life and Health Sciences'. The articles identified were classified according to disease, medical speciality, institutions, major international collaborators, authors and journals.ResultsSri Lanka's cumulative medical publications output between years 2000-2009 was 1,740 articles published in 160 different journals. The average annual publication growth rate was 9.1%. Majority of the articles were published in 'International' (n = 950, 54.6%) journals. Most articles were descriptive studies (n = 611, 35.1%), letters (n-345, 19.8%) and case reports (n = 311, 17.9%). The articles were authored by 148 different Sri Lankan authors from 146 different institutions. The three most prolific local institutions were Universities of; Colombo (n = 547), Kelaniya (n = 246) and Peradeniya (n = 222). Eighty four countries were found to have published collaborative papers with Sri Lankan authors during the last decade. UK was the largest collaborating partner (n = 263, 15.1%).Malaria (n = 75), Diabetes Mellitus (n = 55), Dengue (n = 53), Accidental injuries (n = 42) and Lymphatic filariasis (n = 40) were the major diseases studied. The 1,740 publications were cited 9,708 times, with an average citation of 5.6 per paper. The most cited paper had 203 citations, while there were 597 publications with no citations. The Sri Lankan authors' contribution to the global medical research output during the last decade was only 0.086%.ConclusionThe Sri Lankan medical research output during the last decade is only a small fraction of the global research output. There it is a necessity to setup an enabling environment for research, with a proper vision, support, funds and training. In addition, collaborations across the region need to be strengthened to face common regional health challenges.

Project description:BackgroundMelioidosis is a life threatening infectious disease caused by the gram-negative bacillus Burkholderia pseudomallei predominantly found in southeast Asia and northern Australia. Studying the host transcription profiles in response to infection is crucial for understanding disease pathogenesis and correlates of disease severity, which may help improve therapeutic intervention and survival. The aim of this study was to analyze gene expression levels of human host factors in melioidosis patients and establish useful correlation with disease biomarkers, compared to healthy individuals and patients with sepsis caused by other pathogens.MethodsThe study population consisted of 30 melioidosis cases, 10 healthy controls and 10 sepsis cases caused by other pathogens. Total RNA was extracted from peripheral blood mononuclear cells (PBMC's) of study subjects. Gene expression profiles of 25 gene targets including 19 immune response genes and 6 epigenetic factors were analyzed by real time quantitative polymerase chain reaction (RT-qPCR).Principal findingsInflammatory response genes; TLR4, late onset inflammatory mediator HMGB1, genes associated with antigen presentation; MICB, PSMB2, PSMB8, PSME2, epigenetic regulators; DNMT3B, HDAC1, HDAC2 were significantly down regulated, whereas the anti-inflammatory gene; IL4 was up regulated in melioidosis patients compared to sepsis cases caused by other pathogens. Septicaemic melioidosis cases showed significant down regulation of IL8 compared to sepsis cases caused by other pathogens. HMGB1, MICB, PSMB8, PSMB2, PSME2, HDAC1, HDAC2 and DNMT3B showed consistent down regulation of gene expression in melioidosis patients compared to other sepsis infection, irrespective of comorbidities such as diabetes, duration of clinical symptoms and antibiotic treatment.SignificanceSpecific immune response genes and epigenetic regulators are differentially expressed among melioidosis patients and patients with sepsis caused by other pathogens. Therefore, these genes may serve as biomarkers for disease diagnosis to distinguish melioidosis from cases of sepsis due to other infections and therapeutic intervention for melioidosis.
