RESUMO
Methods: This qualitative study was conducted in two phases, using an integrative literature review and individual interviews. Studies were gathered without time restriction from MEDLINE databases, Institute for Scientific Information (ISI), Google Scholar, Scopus, and EMBASE, as well as national databases, including Scientific Information Database and Magiran. The findings of 38 studies that met the inclusion criteria were analyzed through the conventional content analysis method based on the ecological approach. After reviewing and forming the data matrix, purposive sampling was performed among healthcare professionals, elderly tuberculosis patients aged 60 and over, and family caregivers of elderly patients to conduct individual interviews. Data obtained from 20 interviews were analyzed using the directed content analysis method. After coding, the data from individual interviews were entered based on similarity and difference in the categories of data matrix obtained from the literature review. Results: In general, the aforementioned codes were placed in four main categories, including individual factors (i.e., biological factors, affective-emotional factors, behavioral factors, cognitive factors, tuberculosis-related factors, and economic factors), interpersonal factors (i.e., patient's relationship with treatment team and family-related factors), factors related to healthcare service provider centers (i.e., medical centers' facilities and capacity building in healthcare service provider), and extraorganizational factors (i.e., social factors and health policymaking). Conclusion: The results of this study showed that medication adherence in elderly patients with tuberculosis was a complex and multidimensional phenomenon. Therefore, society, policymakers, and healthcare providers should scrutinize the factors affecting medication adherence in this group of patients to plan and implement more effective interventions.
RESUMO
OBJECTIVES: The BIV1-CovIran vaccine is highly effective against COVID-19. The neutralizing potency of all SARS-CoV-2 vaccines seems to be decreased against variants of concern. We assessed the sensitivity of the Alpha (B.1.1.7), Beta (B.1.351), and Delta (B.1.617.2) variants to neutralizing antibodies (NAbs) present in sera from individuals who had received the BIV1-CovIran candidate vaccine compared with an original Wuhan-related strain. METHODS: The ability of vaccine serum to neutralize the variants was measured using the conventional virus neutralization test. The correlation of spike (S) protein antibody and anti-receptor binding domain with neutralizing activity was investigated. RESULTS: The current study demonstrated that 29 of 32 (90.6%; 95% CI: 75.0-98.0) of the vaccinees developed NAbs against a Wuhan-related strain. It is noteworthy that 28 (87.50%) and 24 of 32 (75%) of the recipients were able to produce NAbs against Alpha, Beta, and Delta variants, respectively. Serum virus-neutralizing titres for different SARS-CoV-2 strains were weakly correlated with anti-receptor binding domain antibodies (Spearman r = 36-42, p < 0.05), but not S-binding antibodies (p > 0.05). DISCUSSION: Although there was a reduction in neutralization titres against the Alpha, Beta, and Delta variants compared with the Wuhan strain, BIV1-CovIran still exhibited potent neutralizing activity against the SARS-CoV-2 variants of concern.

OBJECTIVES: This study aimed to estimate the cost of smear-positive drug-susceptible pulmonary tuberculosis (TB) treatment of the patients in the Azadshahr district, Golestan Province, Iran. METHODS: In this retrospective study, all new smear positive pulmonary TB patients who had been registered at the district's health network between April, 2013 and December, 2015 and had successfully completed their treatment were entered into the study (45 patients). Treatment costs were estimated from the provider's perspective using an activity-based costing (ABC) method. RESULTS: The cost of treating a new smear-positive pulmonary TB patient was US dollar (USD) 1,409.00 (Iranian Rial, 39,438,260), which can be divided into direct and indirect costs (USD 1,226.00 [87%] and USD 183.00 [13%], respectively). The highest cost (58.1%) was related to care and management of TB patients (including 46.1% human resources costs and 12% directly-observed treatment, short course implementation) and then respectively related to hospitalization (12.1%), supportive activity centers (11.4%), transportation (6.5%), medicines (5.3%), and laboratory tests and radiography (3.2%). CONCLUSION: Using disease-specific cost studies can help the healthcare system management to have correct insight into the financial burden created by the disease. This can subsequently be used in prioritization, planning, operational budgeting, economic evaluation of programs, interventions, and ultimately in disease management.
RESUMO
OBJECTIVES: Rehospitalization is a significant burden for transplant systems, which use data on hospitalization to monitor practice outcomes. In this study, all rehospitalizations after successful lung transplant performed in our medical center during an 8-year period were assessed for cause, health care resource use, cost, and outcome. MATERIALS AND METHODS: We performed a retrospective chart review of all rehospitalizations of lung transplant recipients in Masih Daneshvari Hospital in Darabad, Tehran, between 2000 and 2008. Baseline data (each patient's age at transplant and rehospitalization, sex, primary lung disease, medications used), cause of rehospitalization (infection, graft rejection, surgical complications, type of infection), health care resources use (length of hospital stay, intensive care unit stay, physician visits, imaging), rehospitalization costs (accommodations, personnel, drugs, paraclinical [ie, laboratory] tests, supplies, procedures) and outcome (death, survival) were noted. RESULTS: In 69% of patients who were rehospitalized after having received a lung transplant, the cause was infection. Other causes were acute rejection in 31% and surgical complications in 6.9%. In 10.3% of those patients, the primary cause for rehospitalization could not be specified. The mean (SD) duration of rehospitalization was 12.8 -/+ 10.4 days. Treatment in the intensive care unit was necessary for 93.1% of the study subjects. The mean (SD) number of physician visits was 27.8 -/+ 27.7, and the fatality rate in the patients studied was 13.8%. CONCLUSIONS: These data may guide the monitoring of the causes, burden, and outcomes of lung transplants performed in our medical center in Iran and in other medical centers.
