RESUMO

The World Health Organization (WHO) Global Hearts Initiative offers technical packages to reduce the burden of cardiovascular diseases through population-wide and targeted health services interventions. The Pan American Health Organization (PAHO) has led implementation of the HEARTS in the Americas Initiative since 2016. The authors mapped the developmental stages, barriers, and facilitators to implementation among the 371 primary health care centers in the participating 12 countries. The authors used the qualitative method of document review to examine cumulative country reports, technical meeting notes, and reports to regional stakeholders. Common implementation barriers include segmentation of health systems, overcoming health care professionals' scope of practice legal restrictions, and lack of health information systems limiting operational evaluation and quality improvement mechanisms. Main implementation facilitators include political support from ministries of health and leading scientific societies, PAHO's role as a regional catalyst to implementation, stakeholder endorsement demonstrated by incorporating HEARTS into official documents, and having a health system oriented to primary health care. Key lessons include the need for political commitment and cultivating on-the-ground leadership to initiate a shift in hypertension care delivery, accompanied by specific progress in the development of standardized treatment protocols and a set of high-quality medicines. By systematizing an implementation strategy to ease integration of interventions into delivery processes, the program strengthened technical leadership and ensured sustainability. These study findings will aid the regional approach by providing a staged planning model that incorporates lessons learned. A systematic approach to implementation will enhance equity, efficiency, scale-up, and sustainability, and ultimately improve population hypertension control.

RESUMO

BACKGROUND: The challenge of managing non-muscle-invasive bladder cancer (NMIBC) is its high recurrence rate. Clinical investigations have begun to explore the role of androgen suppression as an adjunct to bladder cancer (BC) treatment. OBJECTIVE: To examine the effect of androgen suppression therapy (AST) on recurrence and progression rate of risk-stratified NMIBC. DESIGN, SETTING, AND PARTICIPANTS: Male patients with NMIBC were identified retrospectively from a US institutional database between 2001 and 2017. AST included 5α-reductase inhibitor, gonadotropin-releasing hormone agonist, and antiandrogen. Patients who were exposed to AST prior to documented recurrence/progression were included in the treatment arm. BC was risk stratified to investigate the differential response to AST. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Hazard ratios (HRs) for NMIBC recurrence and progression were estimated using Cox proportional hazards multivariate regression models with stepwise method. Recurrence-free survival (RFS) and progression-free survival (PFS) were compared between groups with and without AST. RESULTS AND LIMITATIONS: We identified a total of 274 males with a median follow-up period of 3.1 yr (interquartile range [IQR] 1.5-5.2). Thirty-six patients were exposed to AST with a median duration of 1.7 yr (IQR 0.7-2.6). AST was associated with a lower risk of recurrence (HR 0.53, 95% confidence interval 0.30-0.88) as well as improved RFS (p = 0.014). However, no significant reduction of progression or improvement of PFS (p = 0.23) was found with AST. After risk stratification, all five patients who progressed in the AST cohort had high-risk disease on initial transurethral resection (TUR), whereas no patients with low/intermediate-risk disease progressed on AST. Limitations of the study include nonstandardized initiation of AST in relation to initial TUR, lack of androgen level quantification, and small sample size in the treatment arm. CONCLUSIONS: In this retrospective, single-institution study, AST was associated with a lower risk of recurrence in NMIBC. No significant association between AST and progression was found. Further investigation is warranted to define the role of AST as an adjunctive therapy for NMIBC. PATIENT SUMMARY: Non-muscle-invasive bladder cancer is a highly recurrent disease that often requires patients to undergo repeated surgical treatments. This single-institution report suggests that medical suppression of androgen may be a potential preventive therapy to reduce recurrence in certain patients.

RESUMO

The effect of hydraulic retention time (HRT) on the microbial community during acid mine drainage (AMD) treatment was investigated. Physicochemical and molecular (illumina and qPCR) analyses were performed on reactive mixtures collected from seven bioreactors in three-operation period (8, 17 and 36weeks). Long HRT (4day) favored the relative abundance of SRB, causing the increase of residual sulfides and short HRT (1day) affected the anaerobic conditions of the bioreactors and favored the presence the acidophilic chemolithotrophic microorganisms. Besides qPCR indicated that genes related to cellulose degradation were present in low copy numbers and were affected by the HRT. Finally, environmental factors (pH, organic source, metal sulfides, and sulfate concentrations) had significant impact on relative abundance of the phylogenetic lineages, rather than the types of lineages present in the reactive mixture. The findings of this study indicate that HRT affects the stability of passive bioreactors and their microbial communities.

RESUMO

Biochemical passive treatment represents a promising option for the remediation of acid mine drainage. This study determined the effect of three hydraulic retention times (1, 2, and 4 days) on changes in system efficiency, reactive mixture, and microbial activity in bioreactors under upward flow conditions. Bioreactors were sacrificed in the weeks 8, 17 and 36, and the reactive mixture was sampled at the bottom, middle, and top layers. Physicochemical analyses were performed on reactive mixture post-treatment and correlated with sulfate-reducing bacteria and cellulolytic and dehydrogenase activity. All hydraulic retention times were efficient at increasing pH and alkalinity and removing sulfate (>60%) and metals (85-99% for Fe(2+) and 70-100% for Zn(2+)), except for Mn(2+). The longest hydraulic retention time (4 days) increased residual sulfides, deteriorated the quality of treated effluent and negatively impacted sulfate-reducing bacteria. Shortest hydraulic retention time (1 day) washed out biomass and increased input of dissolved oxygen in the reactors, leading to higher redox potential and decreasing metal removal efficiency. Concentrations of iron, zinc and metal sulfides were high in the bottom layer, especially with 2 day of hydraulic retention time. Sulfate-reducing bacteria, cellulolytic and dehydrogenase activity were higher in the middle layer at 4 days of hydraulic retention time. Hydraulic retention time had a strong influence on overall performance of passive reactors.

RESUMO

Despite its benefits for people living with HIV/AIDS (PLWHA), home-based care (HBC) may have negative effects on caregivers. Caregivers experience high levels of burden and may be targets of HIV-related prejudice and discrimination. In this cross-sectional survey of 358 caregivers from five hospices across KwaZulu-Natal, South Africa, 49 (13.7%) caregivers personally experienced discrimination as a result of caring for PLWHA. One hundred and seventy (47.5%) marked one or more items on the HIV stigma scale. Eighty-eight percent had low to moderate levels of caregiver burden. People with higher level of burden and higher income were more likely to hold stigmatizing beliefs. Caregivers with the following characteristics: support from a nurse, support from community careworker, HIV stigmatizing beliefs, and personal experience of discrimination as result of caring for PLWHA and low caregiver burden, had more than twice the odds of wanting to care for another PLWA in the future. Overall, caregivers in HBC experience low level of severe caregiver burden. The support offered to caregivers from the hospice and relatively low levels of discrimination encourage expansion of HBC programs for PLWHA.

RESUMO

Congenital heart block (CHB) is the main complication of neonatal lupus (NL) and is strongly associated with the presence of anti-SSA/Ro and anti-SSB/La antibodies. The recurrence of CHB in subsequent pregnancies in mothers with these antibodies is uncommon, occurring in approximately 15% of cases. We describe here a case of recurrent CHB in a previously asymptomatic mother with Sjögren syndrome and discuss the current strategies for the prevention and treatment of CHB in NL.
