Under-utilization of health care services for infectious diseases syndromes in rural Azerbaijan: A cross-sectional study

Background  

Infectious diseases present a potentially substantial yet undefined burden on the health of the adult Azerbaijani population. Efforts to quantify this burden in Azerbaijan are currently based almost exclusively on passive disease surveillance, and therefore hinge on the health utilization practices of the population. Understanding the prevalence of infectious syndromes and health utilization practices is paramount to disease surveillance, public health planning, and health care system reform.     

Development of three quantitative real-time PCR assays for the detection of Rickettsia raoultii,Rickettsia slovaca,and Rickettsia aeschlimannii and their validation with ticks from the country of Georgia and the Republic of Azerbaijan

A previous surveillance study of human pathogens within ticks collected in the country of Georgia showed a relatively high infection rate for Rickettsia raoultii, R. slovaca, and R. aeschlimannii. These 3 spotted fever group rickettsiae are human pathogens: R. raoultii and R. slovaca cause tick-borne lymphadenopathy (TIBOLA), and R. aeschlimannii causes an infection characterized by fever and maculopapular rash. Three quantitative real-time polymerase chain reaction (qPCR) assays, Rraoul, Rslov, and Raesch were developed and optimized to detect R. raoultii, R. slovaca, and R. aeschlimannii, respectively, by targeting fragments of the outer membrane protein B gene (ompB) using species-specific molecular beacon or TaqMan probes. The 3 qPCR assays showed 100% specificity when tested against a rickettsiae DNA panel (n = 20) and a bacteria DNA panel (n = 12). The limit of detection was found to be at least 3 copies per reaction for all assays. Validation of the assays using previously investigated tick nucleic acid preparations, which included Rickettsia-free tick samples, tick samples that contain R. raoultii, R. slovaca, R. aeschlimannii, and other Rickettsia spp., gave 100% sensitivity for all 3 qPCR assays. In addition, a total of 65 tick nucleic acid preparations (representing 259 individual ticks) collected from the country of Georgia and the Republic of Azerbaijan in 2009 was tested using the 3 qPCR assays. R. raoultii, R. slovaca, and R. aeschlimannii were not detected in any ticks (n = 31) from the Republic of Azerbaijan, but in the ticks from the country of Georgia (n = 228) the minimal infection rate for R. raoultii and R. slovaca in Dermacentor marginatus was 10% and 4%, respectively, and for R. aeschlimannii in Haemaphysalis sulcata and Hyalomma spp. it was 1.9% and 20%, respectively.     

Seroprevalence of tularemia in rural Azerbaijan

A representative, two-stage probability sampling design was used to select 40 villages in northern Azerbaijan with populations of <500 people to screen for evidence of prior infection with Francisella tularensis. Informed consent was provided, and samples were obtained from 796 volunteers and tested for the presence of immunoglobulin G antibodies using enzyme-linked immunosorbent assay. F. tularensis seropositivity was prevalent (15.5% of volunteers), but there was minimal reporting of signs and symptoms consistent with clinical tularemia, suggesting that mild or asymptomatic infection commonly occurs. Frequently seeing rodents around the home was a risk factor for seropositivity (POR?=?1.6, p?=?0.03), controlling for age and gender. Geospatial analysis identified associations between village-level tularemia prevalence and suitable tick habitats, annual rainfall, precipitation in the driest quarter, and altitude. This study contributes to the growing understanding of the geographic distribution of tularemia and provides further information on the climatic and landscape conditions that increased the potential for exposure to this pathogen. The potential occurrence of asymptomatic or mild F. tularensis infection warrants further study.     

Worldwide child and adolescent mental health begins with awareness: a preliminary assessment in nine countries

To temper untoward mental health outcomes in children and adolescents, the World Psychiatric Association's Presidential Global Child Mental Health Programme, in collaboration with the WHO and the International Association of Child and Adolescent Psychiatry and Allied Professionals, established a Child Mental Health Awareness Task Force headed by Sam Tyano. Its task was to develop methodologies to increase awareness among policy-makers, community leaders, health professionals, teachers, parents, and children. Based on a prior comprehensive international search for effective techniques for information dissemination, an awareness manual was written for use by health professionals in diverse communities so as to guide the design and implementation of location specific awareness campaigns. We assessed the children, parents and teachers both before and after the campaign to determine changes in knowledge, attitudes and understanding of mental health. The school-based studies were conducted in selected communities in nine countries on five different continents distinguished by their different languages, cultures and their differing levels of economic development: Armenia, Azerbaijan, Brazil, China, Egypt, Georgia, Israel, Russia, and Uganda. In the six sites that completed all assessments, indicators of positive change in awareness of child mental health were identified, and results demonstrated an increased willingness to discuss emotional problems freely. These data support the utility of collaborating with schools so as to foster better child mental health in such under-resourced communities.
