Tracking the evolution of anti-SARS-CoV-2 antibodies and long-term humoral immunity within 2 years after COVID-19 infection.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that gave rise to COVID-19 infection produced a worldwide health crisis. The virus can cause a serious or even fatal disease. Comprehending the complex immunological responses triggered by SARS-CoV-2 infection is essential for identifying pivotal elements that shape the course of the disease and its enduring effects on immunity. The span and potency of antibody responses provide valuable perspicuity into the resilience of post-infection immunity. The analysis of existing literature reveals a diverse controversy, confining varying data about the persistence of particular antibodies as well as the multifaceted factors that impact their development and titer, Within this study we aimed to understand the dynamics of anti-SARS-CoV-2 antibodies against nucleocapsid (anti-SARS-CoV-2 (N)) and spike (anti-SARS-CoV-2 (N)) proteins in long-term immunity in convalescent patients, as well as the factors influencing the production and kinetics of those antibodies. We collected 6115 serum samples from 1611 convalescent patients at different post-infection intervals up to 21 months Study showed that in the fourth month, the anti-SARS-CoV-2 (N) exhibited their peak mean value, demonstrating a 79% increase compared to the initial month. Over the subsequent eight months, the peak value experienced a modest decline, maintaining a relatively elevated level by the end of study. Conversely, anti-SARS-CoV-2 (S) exhibited a consistent increase at each three-month interval over the 15-month period, culminating in a statistically significant peak mean value at the study's conclusion. Our findings demonstrate evidence of sustained seropositivity rates for both anti-SARS-CoV-2 (N) and (S), as well as distinct dynamics in the long-term antibody responses, with anti-SARS-CoV-2 (N) levels displaying remarkable persistence and anti-SARS-CoV-2 (S) antibodies exhibiting a progressive incline.

Factors Influencing Treatment Adherence Among Drug-Sensitive Tuberculosis (DS-TB) Patients in Armenia: A Qualitative Study.

Purpose: Despite the availability of effective treatment, tuberculosis (TB) is still one of the leading causes of mortality around the globe. Poor adherence to treatment challenges TB management both globally and locally. Proper adherence to treatment contributes to successful outcomes and prevents the development of drug-resistant forms of TB. Patients and Methods: We conducted a qualitative study to identify and describe the factors that facilitated treatment adherence among drug-sensitive TB (DS-TB) patients in Armenia. Sixteen in-depth interviews (IDIs) with former DS-TB patients, two IDIs with family members of former DS-TB patients, and a focus group discussion with healthcare providers who manage DS-TB patients were conducted. The educational and ecological assessment component of the PRECEDE-PROCEED model was applied as a conceptual framework to guide the interview content and data analysis. Results: Former patients' awareness of TB and its treatment, beliefs about TB, trust in TB healthcare providers, and a sense of responsibility were the most common factors that predisposed them to complete the treatment. Support received from providers, family, and friends, a desire to avoid TB-associated stigma, and good tolerance of TB medications were the main reinforcing factors. Enabling factors included a relatively simple regimen of TB treatment and accessibility and affordability of TB services. Conclusion: The findings of the study provide new perspectives on factors that facilitate adherence to long-term therapies, such as TB. Interventions that aim to invoke a patient's sense of responsibility and positive beliefs about TB as well as engage families might promote the successful completion of treatment.

Mental health interventions for rifampicin-resistant tuberculosis patients with alcohol use disorders, Zhytomyr, Ukraine.

INTRODUCTION: Despite concerted efforts, Ukraine is challenged by increasing rates of multidrug and rifampicin-resistant tuberculosis (MDR/RR-TB) comorbid with alcohol use disorder (AUD). This study describes a cohort of RR-TB patients with high alcohol consumption treated in MSF Zhytomyr Project, Ukraine. METHODOLOGY: We used programmatic data for 73 RR-TB patients screened with the AUD Identification Test March-July 2019 and followed-up for culture conversion/TB treatment outcome till 31 January 2020. We described socio-demographic, behavioral, and clinical characteristics, the level of depressive symptoms, and TB treatment outcomes in three groups: 1) patients with AUD who received mental health interventions (MHI); 2) patients with AUD who did not receive MHI; 3) patients with no AUD. We also found three potential contributors to declining to receive MHI. RESULTS: Main characteristics of the study groups did not differ substantially. Those receiving MHI (mean: nine sessions) were rated for alcohol consumption as 'hazardous' (41%), 'harmful' (43%) and 'dependence' (36%) and had higher depression scores versus the second (p=0.009) and third (p=0.095) groups at baseline. Depressive symptoms declined at 9-month follow-up for all patients. Culture conversion was seen at 77%, 73%, and 83% for each group respectively. We also found three reasons for declining from MHI. CONCLUSIONS: We detected little differences across the groups. However, our study cohort demonstrated substantially higher adherence rates, culture conversion and reduction of depressive symptoms than reported globally. We recommend further research on the effectiveness of MHI in changing the drinking habits, quality of life and/or TB treatment outcomes of patients with AUD.

Short and long-term outcomes of video observed treatment in tuberculosis patients, the Republic of Moldova.

INTRODUCTION: The Republic of Moldova is among the 18 high priority countries for tuberculosis (TB) in Europe. This study compared adherence and short and long-term TB treatment outcomes for TB patients who experienced asynchronous Video Observed Treatment (aVOT) during three months of outpatient treatment versus Directly Observed Treatment (DOT) in operational conditions in 2016-2017 in Chisinau. METHODOLOGY: We used secondary data from the 2016-2017 Randomized Clinical Trial (RCT) that piloted the aVOT Strategy in Chisinau and data from the national TB register. Relative risk was selected as a measure of association in analysis of treatment strategies (aVOT and DOT under operational conditions) and short and long-term treatment outcomes. RESULTS: From 647 TB patients included in the study, 169 followed the treatment strategy in the RCT (83 in aVOT and 86 in DOT) and 478 were on DOT in operational conditions. Those in aVOT were more likely to have favourable short-term outcome than patients with DOT in operational conditions (RR 0.07; p < 0.001). TB recurrence as an indicator for the long-term outcome, was observed in group with DOT in operational conditions (40 cases, p = 0.006). CONCLUSIONS: This study demonstrated that the aVOT treatment strategy was associated with better adherence and both short and long-term TB treatment favourable outcomes. aVOT as a new patient-centred approach supporting TB patients on improving treatment adherence and outcomes might be recommended as an alternative to DOT strategy in the Republic of Moldova.

Healthcare in transition in the Republic of Armenia: the evolution of emergency medical systems and directions forward.

Armenia, an ex-Soviet Republic in transition since independence in 1991, has made remarkable strides in development. The crisis of prioritization that has plagued many post-Soviet republics in transition has meant differential growth in varied sectors in Armenia. Emergency systems is one of the sectors which is neglected in the current drive to modernize. The legacy of the Soviet Semashko system has left a void in specialized care including emergency care. This manuscript is a descriptive overview of the current state of emergency care in Armenia using in-depth key informant interviews and review of published and unpublished internal United States Agency for International Development (USAID) and Ministry of Health (MOH) documents as well as data from the Yerevan Municipal Ambulance Service and international agencies. The Republic of Artsakh is briefly discussed.The development of emergency care systems is an extremely efficient way to provide care across many different conditions in many age groups. Conditions such as traumatic injuries, heart attacks, cardiac arrest, stroke, and respiratory failure are very time-dependent. Armenia has a decent emergency infrastructure in place and has the benefit of an educated and skilled physician workforce. The missing piece of the puzzle appears to be investment in graduate and post-graduate education in emergency care and development of hospital-based emergency care for stabilization of stroke, myocardial infarction, trauma, and sepsis as well as other acute conditions.

New approach for tuberculosis contact tracing implemented in the two regions of Kyrgyz Republic during 2017-2018.

INTRODUCTION: Tuberculosis (TB) contact investigation as a proved approach for finding new TB cases, is not fully performed in Kyrgyzstan. In 2018, the country started aligning the National Guidelines for tracking contacts with the WHO recommendations by expanding the definition for TB index cases to all close contacts, regardless of their TB risk status. METHODOLOGY: This cross-sectional census aimed to determine the active case detection changes among TB contacts after implementation of a new TB tracing strategy using the National Surveillance data. We compared populations in Chui and Issyk-Kul regions of Kyrgyzstan who had contacts with TB index cases before (2017) and after (2018) strategic changes for the rates of indexes, contacts, screened contacts, and detected TB among screened contacts. RESULTS: New TB tracing strategy resulted in increased numbers of indexes (21%) and contacts (36%). Though the smaller number of contacts (1730 vs. 1590) have been screened in 2018, the proportion of TB diagnosed was substantially higher (95% CI: 0.024-0.005; p = 0.002) in 2018 vs. 2017. The mean numbers of TB contacts per-one-index-case also has increased dramatically by 117% (1.8 vs. 3.9) in Chui and by 43% (3.0 vs. 4.3) in Issyk-Kul regions (95% CI: 3.20-3.37; p < 0.001 and 95% CI: 2.97-3.09; p < 0.001, respectively) between 2018 and 2017. CONCLUSION: Extending new tracing approach to other regions of Kyrgyzstan will increase the number of identified contacts, leading to better TB control in the country and prevention of more severe TB development among the unidentified contacts.

The survival rate of tuberculosis patients in HIV-treated cohort of 2008-2018 in Almaty, Kazakhstan.

INTRODUCTION: HIV/TB comorbidity is responsible for 1.6 million deaths worldwide. HIV/TB control and patients' survival are still among priorities of the national HIV and TB programs. We aimed to evaluate the HIV/TB survival in connection with TB treatment outcomes and factors influencing life duration of the cohort 2008-2018 in Almaty, Kazakhstan. METHODOLOGY: This retrospective cohort study extracted data for all HIV and pulmonary TB adults coinfected during 2008-2018 in Almaty from national registries to apply descriptive, Kaplan-Meier estimation, and Cox proportional hazards regression model. Survival function for the TB treatment outcomes and factors predicting the probability of survival were tested and described. RESULTS: The cohort population (n = 521) mean age was 37.4 years with 405 (77.7%) males and 210 (40.3%) marrieds. More than one TB treatment had 181 (34.7%) patients, 291 (55.9%) were smear-positive (SS+), and 423 (81.2%) were on antiretroviral therapy with mean CD4 count 254.22cells/µL. Probability to live longer was higher (128 versus 37 months, p = 0.003; 95% confidence interval (CI) 71.65, 184.35) for those who succeeded in TB treatment compared to "lost to follow-up" and "failed" treatment outcomes. Adjusted Cox regression model death hazard showed association with missing ART treatment (HR: 1.699, 95%CI 1.164, 2.481, p = 0.006) and having CD4 count < 499 (HR 2.398, 95%CI 1.191, 4.830, p < 0.014). CONCLUSION: TB treatment outcomes, ART treatment, and the CD4 count of HIV/TB coinfected population substantially influence their life duration. The medical decision- and policy-makers should take this into consideration when implementing targeted improvements in the national HIV and TB programs.

People-centred care versus clinic-based DOT for continuation phase TB treatment in Armenia: a cluster randomized trial.

BACKGROUND: WHO's directly observed therapy (DOT) strategy for tuberculosis (TB) treatment depends upon a well-organized healthcare system. This study sought to evaluate the effectiveness of self-administered drug intake supported by a family member versus in-clinic DOT. METHODS: This open-label, nationally-representative stratified cluster randomized controlled non-inferiority trial with two parallel equal arms involved drug-susceptible pulmonary TB patients in the continuation treatment phase. We randomly assigned outpatient-TB-centres (52 clusters) to intervention and control arms. The intervention included an educational/counseling session to enhance treatment adherence; weekly visits to outpatient-TB-centres to receive medication, and daily SMS medication reminders and phone calls to track adherence and record side effects. Controls followed clinical DOT at Outpatient-TB-centres. Both groups participated in baseline and 4-5 months follow-up surveys. The trial's non-inferiority comparisons include: treatment success as the clinical (primary) outcome and medication adherence (self-reported), knowledge, depressive symptoms, stigma, quality of life, and social support as non-clinical (secondary) outcomes. RESULTS: Per-protocol analysis showed that the intervention (n = 187) and control (n = 198) arms achieved successful treatment outcome of 92.0 and 92.9%, respectively, indicating that the treatment success in the intervention group was non-inferior to DOT. Knowledge, depression, stigma, quality of life, and social support also showed non-inferiority, demonstrating substantial improvement over time for knowledge (change in the intervention = 1.05: 95%CL (0.49, 1.60); change in the control = 1.09: 95%CL (0.56, 1.64)), depression score (change in the intervention = - 3.56: 95%CL (- 4.99, - 2.13); change in the control = - 1.88: 95% CL (- 3.26, - 0.49)) and quality of life (change in the intervention = 5.01: 95%CL (- 0.64, 10.66); change in the control = 7.29: 95%CL (1.77, 12.81)). The intervention resulted in improved treatment adherence. CONCLUSIONS: This socially empowering alternative strategy might be a preferable alternative to DOT available to patients in Armenia and in other countries. Further research evaluating cost effectiveness of the intervention and generalizability of the results is warranted. TRIAL REGISTRATION: Clinicaltrials.gov: NCT02082340, March 10, 2014.

Quality of Inpatient Tuberculosis Health Care in High-Burden Resource-Limited Settings: Protocol for a Comprehensive Mixed Methods Assessment Study.

BACKGROUND: The quality of care for tuberculosis (TB) is deficient in high-burden countries and urgently needs improvement. However, comprehensively identifying the required improvements is challenging. Providing high-quality TB care is an important step toward improving patients' quality of life and decreasing TB morbidity and mortality. Effective tools for assessing the quality of TB services using international standards and guidelines can identify existing gaps in services and inform improvements to ensure high-quality inpatient TB services. OBJECTIVE: This study aimed to develop evaluation instruments for defining the quality of provision of TB services. METHODS: To assess quality of services in the largest TB hospital in Armenia, we developed instruments based on the Joint Commission International Accreditation Standards for Hospitals, International Standards for TB Care, TB Laboratories Bio-Safety Standards, and the World Health Organization framework for conducting TB program reviews. A mixed methods approach was utilized, triangulating quantitative (checklists) and qualitative (in-depth interviews) results. A scoring system and strengths, weaknesses, opportunities, and treats analysis was applied to detail results for each of the 122 standards assessed. A scaling approach was used to present overall performances of inpatient services for eight patient-centered functions and five organization management functions. RESULTS: Overall, 40 in-depth interviews and 91 checklists (21 observations, 16 policy papers, 20 staff qualification documents, and 34 medical records) were developed, utilized, and analyzed to explore practices of health care professionals, assess inpatient treatment experience of patients and their family members, evaluate facility environmental conditions, and define the degree of compliance to standards. CONCLUSIONS: The effective comprehensive evaluation instruments and methods developed in this study for quality of inpatient TB services support the implementation of similar effective assessments in other countries. It may also become a platform to develop similar approaches for assessing ambulatory TB services in resource-limited countries.

Smoking cessation knowledge, attitude and practices among tuberculosis physicians: A qualitative study.

INTRODUCTION: Smoking cessation interventions within tuberculosis (TB) care are feasible, effective and efficient for increasing smoking cessation rates. We aimed to assess TB physicians' smoking cessation knowledge, attitude, and practices (KAP). METHODS: We conducted a qualitative study with 21 TB physicians and utilized directed deductive content analysis with predefined knowledge, attitude, and practice categories. Physicians' practice was analyzed using the ABC approach (Ask, Brief advice, and Cessation support). RESULTS: Physicians acknowledged the importance of quitting for improved treatment outcomes and decreased risk of TB relapse. Physicians revealed presumed drug interactions, possible side effects of pharmacotherapy, and reluctance to take additional medications as challenges of smoking cessation interventions. Physicians asked about smoking behavior and provided a brief quitting advice to TB patients; however, implementation of cessation support was limited due to poor knowledge of evidence-based cessation methods and the absence of formal tobacco dependence treatment algorithms within TB care. CONCLUSIONS: TB physicians' KAP on smoking cessation was limited. Interventions targeting physicians' knowledge and skills, and formalization of tobacco dependence treatment within TB care, are core for improving their smoking cessation practices in Armenia.

People-centered tuberculosis care versus standard directly observed therapy: study protocol for a cluster randomized controlled trial.

BACKGROUND: Tuberculosis is a major public health concern resulting in high rates of morbidity and mortality worldwide, particularly in low- and middle-income countries. Tuberculosis requires a long and intensive course of treatment. Thus, various approaches, including patient empowerment, education and counselling sessions, and involvement of family members and community workers, have been suggested for improving treatment adherence and outcome. The current randomized controlled trial aims to evaluate the effectiveness over usual care of an innovative multicomponent people-centered tuberculosis-care strategy in Armenia. METHODS/DESIGN: Innovative Approach to Tuberculosis care in Armenia is an open-label, stratified cluster randomized controlled trial with two parallel arms. Tuberculosis outpatient centers are the clusters assigned to intervention and control arms. Drug-sensitive tuberculosis patients in the continuation phase of treatment in the intervention arm and their family members participate in a short educational and counselling session to raise their knowledge, decrease tuberculosis-related stigma, and enhance treatment adherence. Patients receive the required medications for one week during the weekly visits to the tuberculosis outpatient centers. Additionally, patients receive daily Short Message Service (SMS) reminders to take their medications and daily phone calls to assure adherence and monitoring of treatment potential side effects. Control-arm patients follow the World Health Organization--recommended directly observed treatment strategy, including daily visits to tuberculosis outpatient centers for drug-intake. The primary outcome is physician-reported treatment outcome. Patients' knowledge, depression, quality of life, within-family tuberculosis-related stigma, family social support, and self-reported adherence to tuberculosis treatment are secondary outcomes. DISCUSSION: Improved adherence and tuberculosis treatment outcomes can strengthen tuberculosis control and thereby forestall tuberculosis and multidrug resistant tuberculosis epidemics. Positive findings on effectiveness of this innovative tuberculosis treatment people-centered approach will support its adoption in countries with similar healthcare and economic profiles.

Increased risk for multidrug-resistant tuberculosis in migratory workers, Armenia.

To understand use of tuberculosis (TB) services for migrant workers, we conducted a cross-sectional census of 95 migrant workers with TB from Armenia by using medical record reviews and face-to-face interviews. Prolonged time between diagnosis and treatment, treatment interruption, and treatment defaults caused by migrant work might increase the risk for multidrug-resistant TB.

Practices, attitudes and perceptions toward road safety in yerevan, republic of armenia.

OBJECTIVES: : To determine knowledge and attitudes regarding traffic safety devices, measures, and legislation in the general population in Yerevan, Republic of Armenia. METHODS: : We conducted a baseline random digit dial fixed line telephone verbal survey of Yerevan households in April 2009 with a follow-up survey in May 2010. Survey domains included restraint use, motor vehicle crash experiences, and attitudes regarding traffic safety. RESULTS: : In the initial survey, of 2137 numbers dialed, 436 persons were reached and 390 (90%) agreed to participate. Of survey respondents, 90% percent of household cars had seatbelts, while 47% had airbags. Twenty-four percent always or usually wore a seatbelt when driving, 21% wore a belt as a passenger. 39% were unaware of child restraints. Of the 61% who were aware of child restraints, only 32% had ever used one. A follow-up survey was conducted one year later after enforcement efforts were increased. In the follow-up survey, 81% percent always or usually wore a seatbelt when driving, and 69% wore a belt as a passenger. There was no significant increase of awareness or use of child restraints in the follow-up survey. CONCLUSIONS: : Although cars in Yerevan have seat belts, the majority of drivers and passengers prior to the intervention did not use them. Knowledge and use of child restraints was poor. The follow-up survey conducted after an enforcement campaign was underway in Yerevan showed that improved enforcement greatly increased awareness and compliance with current legislation. This study provides vital baseline information for the formulation of future policy. It also highlights the need for a multi-dimensional road traffic safety initiative through public educational campaigns, enforcement of current laws, and development of novel prevention policies and regulations.

Nursing practice in a post-Soviet country from the perspectives of Armenian nurses: a qualitative exploratory study.

AIMS AND OBJECTIVES: The purpose of this qualitative descriptive study was to explore the views of head and staff nurses about nursing practice in the hospitals of Armenia. BACKGROUND: Armenia inherited its nursing frameworks from the Soviet Union. After the Soviet collapse, many changes took place to reform nursing. However, to date little has been systematically documented about nursing practice in Armenia. DESIGN: Qualitative descriptive design was implemented. METHODS: Three major hospitals in Yerevan, the capital city of Armenia, participated in the study. Purposeful sampling was used. Forty-three nurses participated, 29 staff and fourteen head nurses. Data were collected through five focus groups comprised of seven to ten participants. A focus group guide was developed. The researcher facilitated the discussions in Armenian, which were audio taped. The research assistant took notes. Data were transcribed and translated into English, imported into atlas.ti 6.1 qualitative software, and analysed by three authors. RESULTS: Five themes were extracted. Lack of role clarity theme was identified from the head nurse data. The practice environment theme was identified from the staff nurse data. Nursing education, value, respect and appreciation of nursing, and becoming a nurse were common themes identified from both head and staff nurse data. Head nurses lack autonomy, do not have clear roles and are burdened with documentation. Staff nurses practice in challenging work environments with inadequate staffing and demanding workloads. All nurses reported the need to improve nursing education. CONCLUSIONS: This is the first study conducted in Armenia exploring nursing practice in the hospitals from the nurses' perspectives. Nurses face challenges that may impact their wellbeing and patient care. RELEVANCE TO CLINICAL PRACTICE: Understanding challenges nursing practice faces in the hospitals in Armenia will help administrators and care providers to take actions to improve nursing practice and subsequently patient care.
