ABSTRACT

BACKGROUND: Though dementia rates vary by racial or ethnic groups, it is unknown if these disparities remain among those aged 90 or older. AIMS: To test this hypothesis, we used baseline clinical evaluation of 541 ethnically and racially diverse individuals participating in the LifeAfter90 Study to assess how associations between core demographic characteristics and measures of physical and cognitive performance differ across the racial/ethnic groups. METHODS: Participants in this study were long-term non-demented members of Kaiser Permanente Northern California. They were clinically evaluated and diagnosed with normal or impaired cognition (mild cognitive impairment and dementia) through an in-person comprehensive clinical assessment consisting of a detailed medical history, physical and neurological examination, functional, and cognitive tests. RESULTS: The average age at enrollment was 93.0 ± 2.6 years, 62.4% female and 34.2% non-Hispanic White. At initial evaluation 301 participants had normal cognition and 165 had mild cognitive impairment (MCI) and despite screening, 69 participants were determined to have dementia. Age, education, 3MS, FAQ and CDR scores were significantly associated with cognitive impairment (normal versus MCI and dementia), but not gender. There was a significant univariate association between race/ethnicity and cognitive impairment (p < 0.02) being highest among Black (57.4%) and lowest among Asian (32.7%) individuals. After adjustment for age, gender, and education, however, prevalence of cognitive impairment was not influenced by race or ethnicity. CONCLUSION: Our results confirm the ability to reliably assess clinical diagnosis in a diverse sample of very old individuals.

ABSTRACT

INTRODUCTION: In 2013, the National Tuberculosis (TB) Program of Armenia introduced GeneXpert MTB/RIF (Xpert) assay to address World Health Organization (WHO) target of 80% (2020) of notified new and relapse TB cases to be tested with WHO recommended rapid diagnostic methods. This study aimed to assess the change in laboratory diagnostic profile of Mycobacterium tuberculosis after introduction of the Xpert assay from 2013 to 2017. METHODOLOGY: Retrospective cohort analysis of all presumptive TB patients' records retrieved from the National Reference Laboratory database was performed. RESULTS: This study showed increased trend of Xpert coverage for suspected TB cases from 25% in 2013 to 86% in 2017 which is in line with WHO TB global strategy's target of 80% in 2020. In 4.7% cases, Xpert tested positive while microscopy showed negative results. There was also an improved detection of Rifampicin resistance with increased concordance from 99.1% to 99.4% and decreased discordance from 6.7% to 1.4% between culture and Xpert results. CONCLUSION: Armenia has achieved the 2020 target; in terms of utilizing the GeneXpert it is on track to achieve the End TB strategy target of 100% by 2025. The next step of this research will be assessment of the impact of GeneXpert and other TB tests utilization on the treatment outcomes in Armenia.

ABSTRACT

INTRODUCTION: The incidence of brucellosis in Armenia in 2010 was twice as high as in other countries of the Caucasian region and has almost doubled over the last three decades. This study aimed to investigate factors associated with acute or chronic forms of presentation of human brucellosis. METHODOLOGY: Retrospective study using data from medical records of 455 patients hospitalized for the first time at the Nork Republican Infectious Disease Referral Hospital in Yerevan, Armenia between the years 2006 and 2016. We undertook descriptive analysis of cases, compared acute and chronic cases, and identified factors associated with acute and chronic cases using regression. RESULTS: The majority of brucellosis cases had acute case presentation (73.0%), were males (70.3%), between the ages of 20-60 years (66.2%) and unemployed (89.9%). About two-thirds of cases reported a history of consumption of raw unpasteurized milk. The multivariate analysis revealed that factors associated with the form of brucellosis were age, symptom duration preadmission, fever, antibody titer, and hospitalization outcomes. CONCLUSION: This study revealed that brucellosis is unevenly distributed across different age groups, as well as regions of Armenia. Affected individuals did not seek medical attention after the onset of the symptoms for about 2 months. Therefore, the targeted educational campaigns could be of crucial importance to prevent the disease in humans, contribute to its early diagnosis and treatment.

ABSTRACT

BACKGROUND: Smoke-free policies shown to reduce population exposure to secondhand smoke (SHS) are the norm in hospitals in many countries around the world. Armenia, a transition economy in the South Caucasus, has one of the highest male smoking rates in the European region. Although smoking in healthcare facilities has been banned since 2005, compliance with this ban has been poor due to lack of implementation and enforcement mechanisms and social acceptability of smoking. The study aimed to develop and test a model intervention to address the lack of compliance with the de jure smoking ban. The national oncology hospital was chosen as the intervention site. METHODS: This study used employee surveys and objective measurements of respirable particles (PM2.5) and air nicotine as markers of indoor air pollution before and after the intervention. The intervention developed in partnership with the hospital staff included an awareness campaign on SHS hazards, creation of no-smoking environment and building institutional capacity through training of nursing personnel on basics of tobacco control. The survey analysis included paired t-test and McNemar's test. The log-transformed air nicotine and PM2.5 data were analyzed using paired t-test. RESULTS: The survey showed significant improvement in the perceived quality of indoor air, reduced worksite exposure to SHS and increased employees' awareness of the smoke-free policy. The number of employees reporting compliance with the hospital smoke-free policy increased from 36.0% to 71.9% (p < 0.001). The overall indoor PM2.5 concentration decreased from 222 µg/m3 GM (95% CI = 216-229) to 112 µg/m3 GM (95% CI = 99-127). The overall air nicotine level reduced from 0.59 µg/ m3 GM (95% CI = 0.38-0.91) to 0.48 µg/ m3 GM (95% CI = 0.25-0.93). CONCLUSIONS: The three-faceted intervention developed and implemented in partnership with the hospital administration and staff was effective in reducing worksite SHS exposure in the hospital. This model can facilitate a tangible improvement in compliance with smoke-free policies as the first step toward a smoke-free hospital and serve as a model for similar settings in transition countries such Armenia that have failed to implement the adopted smoke-free policies.

ABSTRACT

Disasters have serious long-term impact on mental health for those exposed. The aim of this study was to identify predictors of postpartum depression among survivors of the 1988 devastating earthquake in Armenia. A nested case-control design was applied to investigate postpartum depression in a large-scale cohort of survivors followed between 1990 and 2012. From an original group of 725 adults who were assessed for psychopathology in 1990, 146 women reported having a delivery after the earthquake and were included in this study. Women with postpartum depression were identified using Edinburgh Postnatal Depression Scale. A logistic regression model was fitted to identify the predictors of postpartum depression. Of the 146 women, 19 (13.0%) had postpartum depression. Five independent predictors of postpartum depression were identified: number of woman's stressful life events (odds ratio (OR)=2.06), her prior history of postpartum depression (OR=16.98), delivering sick/dead neonate (OR=13.65), poor living standards during the post-earthquake decade (OR=5.77), and perceiving oneself reliable in 1990 (OR=0.24). Anxiety in 1990 was marginally significantly related to the outcome (OR=3.75). The rate of postpartum depression in this 22-year cohort was similar to that among the Armenian general population. Earthquake exposure was not related to postpartum depression, indicating that the impact of disaster-related trauma diminishes over time. The identified predictors provided evidence to develop interventions targeting groups of women most prone to postpartum depression under such circumstances.

ABSTRACT

OBJECTIVE: To develop and test an intervention to reduce children's exposure to secondhand smoke (SHS) at homes in Yerevan, Armenia. METHODS: A single-blind, randomized trial in 250 households with 2- to 6-year-old children tested an intensive intervention (counseling sessions, distribution of tailored educational brochures, demonstration of home air pollution, and 2 follow-up counseling telephone calls) against minimal intervention (distribution of standard leaflets). At baseline and 4-month follow-up, researchers conducted biomonitoring (children's hair) and surveys. The study used paired t tests, McNemar's test, and linear and logistic regression analyses. RESULTS: After adjusting for baseline hair nicotine concentration, child's age and gender, the follow-up geometric mean (GM) of hair nicotine concentration in the intervention group was 17% lower than in the control group (P = .239). The GM of hair nicotine in the intervention group significantly decreased from 0.30 ng/mg to 0.23 ng/mg (P = .024), unlike in the control group. The follow-up survey revealed an increased proportion of households with smoking restrictions and decreased exposure of children to SHS in both groups. The adjusted odds of children's less-than-daily exposure to SHS at follow-up was 1.87 times higher in the intervention group than in the control group (P = .077). The GM of mothers' knowledge scores at follow-up was 10% higher in the intervention group than in the control group (P = .006). CONCLUSIONS: Intensive intervention is effective in decreasing children's exposure to SHS through educating mothers and promoting smoking restrictions at home. However, superiority over minimal intervention to decrease children's exposure was not statistically significant.

ABSTRACT

BACKGROUND: To investigate determinants of development of postpartum depression among women in Yerevan, Armenia. METHOD: A case-control study of all reproductive age (18-45) women having 1-3 months old children registered in 7 Primary Health Care (PHC) facilities, in Yerevan. We used Edinburgh Postnatal Depression Scale (EPDS) and a structured questionnaire to assess possible postpartum depression status of mothers and exposure status through telephone interviews. RESULTS: The study had a 96.7% response rate for 63 cases and 272 controls. The prevalence of possible postpartum depression was 14.4%. The risk of possible postpartum depression associated with age less than 25 years at childbirth was increased only among women who delivered their child through C-section (OR=7.8; 95% CI: 1.5-40.7). Meanwhile, this risk was much lower among women who delivered through vaginal delivery (OR=0.9; 95% CI: 0.4-1.8). LIMITATIONS: EPDS had not been translated and validated in Armenia. Study population included only women having 1-3 months old children. CONCLUSION: The study suggested that the effect of younger age at last childbirth on the risk of possible postpartum depression development was higher for women who gave birth through C-section compared to those with vaginal delivery. Despite the stressful and crisis conditions existing in Armenia over the past 2 decades the prevalence of possible postpartum depression does not differ much from that in other societies.
