Psychometric properties of the Creole Haitian version of the Resilience Scale amongst child and adolescent survivors of the 2010 earthquake

Resilience is defined as the capacity of human beings to deal with and adapt to adversity, suffering, tragedy or other traumatic event. This study aims to investigate psychometric properties and the underlying structure of the Creole version of the RS among children and adolescents survivors to the 2010 Haitian earthquake. A total of 872 children and adolescents exposed to the earthquake with an average age of 14.91 (SD = 1.94) completed the Creole version of RS, the Impact Event Scale-Revised, the Children Depression Inventory and the Social Support Questionnaire-6. The current validity of RS and the internal consistency were investigated; sex, age, religion and others socio-demographic variables differences were also analysed. Cronbach’s alpha coefficient for the RS was .77; the split-half coefficient was .72. The goodness-of-fit for the 5-factor model presents the best adjusted indices. The total resilience score was correlated positively with social support (r = .42, p < .01). Mean score of the RS was 131.46 (SD = 21.01). No significant differences were observed about sex, age and residential municipality. The results showed that the Haitian Creole version of RS is a valid and reliable measure in assessing resilience for the children and adolescent survivors to the 2010’s earthquake.

Evaluation of clinical and laboratory correlates of sickle leg ulcers

The exact mechanism for the occurrence of sickle leg ulcers (SLUs) has not been fully explained, although, popular opinion supports a multifactorial etio‐pathogenetic process. Leg ulceration in sickle cell is a chronic and debilitating condition which is difficult to treat and may worsen the psychosocial impact of this illness. This study aims to evaluate the laboratory and clinical correlates of SLUs. One hundred sixty‐seven patients who had been diagnosed with sickle cell anemia (homozygous S) had their steady‐state hemoglobin concentration (Hb), hematocrit, white cell count, platelet count, serum bilirubin, and aspartate transaminase (AST) as well as frequency of crisis per annum evaluated with respect to their relationship to the occurrence of leg ulcers. They were aged 6–53 years (mean age 24.3 years), and prevalence of leg ulcer was found to be 2.75 per 1000 (2.54 per 1000 in females and 2.83 per 1000 in males). The independent sample t‐test showed a significant difference in the serum AST levels in those with SLU (p = 0.029), though a positive correlation did not exist. Other predictors of disease severity found to have positive relationship with each other were the AST and total serum bilirubin 0.207 (p = 0.012); Hb and age 0.130 (p = 0.035); Hb and white cell count ?0.159 (p = 0.010), white cell count and age ?0.113 (p = 0.018). SLUs do not occur in patients with severe disease in sickle cell. The clinical and laboratory indicators of severe sickle cell disease do not correlate positively with the occurrence of SLU. Serum AST may have a relationship with leg ulceration in these patients. Environmental factors most likely play a major part in the etiopathogenesis of leg ulcer and this may require further studies in different sociocultural settings.     

The Arts and Health Communication in Uganda: A Light Under the Table

This qualitative interview study brings the voices of 27 public health leaders, health communication experts, and artists who work in public health in Uganda together to articulate the principles and practices that make the country a shining example of effective, evidence-based use of the arts for health communication. The specific aim of the study was to identify best practices, theoretical foundations, and other factors that contribute to the success of arts-based health communication campaigns in Uganda.

The study presents four primary themes related to use of the arts for health communication in Uganda: (1) the arts empower health communication; (2) the arts engage people emotionally; (3) effective programs are highly structured; and (4) professionalism is critical to program effectiveness. The findings suggest that the arts humanize, clarify, and empower health communication. The arts can attract attention and engage target populations, reduce hierarchical divisions and tensions that can challenge communication between health professionals and community members, make concepts clearer and more personally and culturally relevant, and communicate at an emotional level wherein concepts can be embodied and made actionable. The findings articulate why and how the arts are an effective means for health communication and can guide best practices.

Effect of COVID-19 on the Number of CT-scans and MRI Services of Public Hospitals in Iran: An Interrupted Time Series Analysis

BackgroundIn February 2020, the Ministry of Health and Medical Education in Iran announced the first case of COVID-19. The aim of this study was to investigate the impact of COVID-19 on the number of CT-Scans and MRI services in public hospitals in western Iran.MethodsWe collected CT-scans and MRI services data from 18 public hospitals via Vice-Chancellor Office, Lorestan University of Medical Sciences from January 2017 to February 2021. Interrupted time series analysis (ITSA) was conducted to assess the impact of COVID-19 on CT-Scans and MRI services. More specifically, ITSA was conducted using ordinary least squares regression with the number of CT-Scans and MRI services per 1,000 registered persons per month as dependent variable.ResultsAt the beginning of the observation period, the monthly rate of CT-Scans was constant (p for trend = 0.267) at 291.9 (from 95%CI 240.5 to 343.4) per 1,000 registered patients. The first case of COVID-19 coincided with an abrupt increase by 211.8 (from 95%CI 102.9 to 320.7) per 1,000 patients. Thereafter, the trend of CT-Scans did not change (p=0.576) compared to the pre-pandemic period. The rate of MRI services was 363.5 per 1,000 per registered patients per month (P = <0.0001) with a slightly decreasing trend (coefficient=-5; 95%CI, -6.9 to -3.1).ConclusionThe findings of this study showed that crises such as COVID-19 can affect the service delivery process. Health policymakers and decision makers should work to prevent potential reductions in health care during events such as COVID-19.     

Angiotensin II type 1 receptor blocker inhibits fibrosis in rat nonalcoholic steatohepatitis

Nonalcoholic steatohepatitis (NASH) is now the most frequent cause of chronic liver impairment in developed countries and is a suggested causative factor in the development of cryptogenic cirrhosis and hepatocellular carcinoma. At present there is no effective and accepted therapy for NASH. The renin-angiotensin system is involved in hepatic fibrosis through activation of hepatic stellate cells, major fibrogenic cells in the liver. Hepatic stellate cells are activated by liver injury to express excessive matrix proteins and profibrogenic cytokines such as transforming growth factor-beta 1. Medicines that inhibit this pathway may be of therapeutic potential in NASH. Using a methionine-choline-deficient rat model of NASH, we studied the potential utility of an angiotensin II type 1 receptor blocker (ARB), olmesartan, on biochemical, histologic, and antioxidant measures of disease activity. ARB significantly attenuated increases in aspartate aminotransferase, activation of hepatic stellate cells, oxidative stress, expression of transforming growth factor-beta 1, expression of collagen genes, and liver fibrosis. CONCLUSION: Our observations strongly suggest a potential preventive role for ARB in the progression of nonalcoholic steatohepatitis.
