RESUMEN

BACKGROUND: Influenza vaccines prevent influenza-related morbidity and mortality; however, suboptimal vaccine effectiveness (VE) of non-adjuvanted trivalent inactivated influenza vaccine (naTIV) or quadrivalent formulations in older adults prompted the use of enhanced products such as adjuvanted TIV (aTIV). Here, the VE of aTIV is compared to naTIV for preventing influenza-associated hospitalization among older adults. METHODS: A test-negative design study was used with pooled data from the 2012 to 2015 influenza seasons. An inverse probability of treatment (IPT)-weighted logistic regression estimated the Odds Ratio (OR) for laboratory-confirmed influenza-associated hospitalization. VE was calculated as (1-OR)*100% with accompanying 95% confidence intervals (CI). RESULTS: Of 7,101 adults aged ≥ 65, 3,364 received naTIV and 526 received aTIV. The overall VE against influenza hospitalization was 45.9% (95% CI: 40.2%-51.1%) for naTIV and 53.5% (42.8%-62.3%) for aTIV. No statistically significant differences in VE were found between aTIV and naTIV by age group or influenza season, though a trend favoring aTIV over naTIV was noted. Frailty may have impacted VE in aTIV recipients compared to those receiving naTIV, according to an exploratory analysis; VE adjusted by frailty was 59.1% (49.6%-66.8%) for aTIV and 44.8% (39.1%-50.0%) for naTIV. The overall relative VE of aTIV to naTIV against laboratory-confirmed influenza hospital admission was 25% (OR 0.75; 0.61-0.92), demonstrating statistically significant benefit favoring aTIV. CONCLUSIONS: Adjusting for frailty, aTIV showed statistically significantly better protection than naTIV against influenza-associated hospitalizations in older adults. In future studies, it is important to consider frailty as a significant confounder of VE.

RESUMEN

Background: The COVID-19 pandemic caused considerable burden on mental health worldwide. To address this emergency in Peru, Socios en Salud (SES) implemented an innovative digital system for the diagnosis and psychological therapy in vulnerable populations. We describe the development, implementation, and participant outcomes of this intervention. Methods: We conducted an intervention in a general population of Lima, Peru using a digital tool, ChatBot-Juntos, incorporating the abbreviated Self-Reporting Questionnaire (SRQ) to screen psychological distress. Participants positive for psychological distress received remote Psychological First Aid (PFA) and grief therapy if needed. Participants with a mental health condition or safety concern were referred to mental health services. SRQ scores were collected 3 months after PFA sessions. Differences between screening and follow-up scores were compared using Wilcoxon sign-rank test. Results: In total, 2027 people were screened; 1581 (77.9%) screened positive for psychological distress. Nine hundred ninety-seven (63%) people with psychological distress received PFA, and 320 (32.1%) of those were also referred for mental health care. At 3 months after follow-up, SRQ scores were collected for 579 (58%) participants. Significant reduction in SRQ scores was observed 3 months after PFA [median SRQ score changed from 9 to 5 (p < 0.001)], and after PFA plus referral to mental health services [median SRQ score changed from 11 to 6 (p < 0.001)]. Conclusion: Digital technology can be used to screen for psychological distress and deliver mental health support for populations affected by the COVID-19 pandemic. More research is needed to determine whether technology contributes to improved mental health outcomes.

RESUMEN

INTRODUCTION: Effective digital health management information systems (HMIS) support health data validity, which enables health care teams to make programmatic decisions and country-level decision making in support of international development targets. In 2015, mental health was included within the Sustainable Development Goals, yet there are few applications of HMIS of any type in the practice of mental health care in resource-limited settings. Zanmi Lasante (ZL), one of the largest providers of mental health care in Haiti, developed a digital data collection system for mental health across 11 public rural health facilities. PROGRAM INTERVENTION: We describe the development, implementation, and evaluation of the digital system for mental health data collection at ZL. To evaluate system reliability, we assessed the number of missing monthly reports. To evaluate data validity, we calculated concordance between the digital system and paper charts at 2 facilities. To evaluate the system's ability to inform decision making, we specified and then calculated 4 priority indicators. RESULTS: The digital system was missing 5 of 143 monthly reports across all facilities and had 74.3% (55/74) and 98% (49/50) concordance with paper charts. It was possible to calculate all 4 indicators, which led to programmatic changes in 2 cases. In response to implementation challenges, it was necessary to use strategies to increase provider buy-in and ultimately to introduce dedicated data clerks to keep pace with data collection and protect time for clinical work. LESSONS LEARNED: While demonstrating the potential of collecting mental health data digitally in a low-resource rural setting, we found that it was necessary to consider the ongoing roles of paper records alongside digital data collection. We also identified the challenge of balancing clinical and data collection responsibilities among a limited staff. Ongoing work is needed to develop truly sustainable and scalable models for mental health data collection in resource-limited settings.

RESUMEN

Problem Management Plus (PM+) is a low-intensity psychological intervention developed by the World Health Organization that can be delivered by nonspecialists to address common mental health conditions in people affected by adversity. Emerging evidence demonstrates the efficacy of PM+ across a range of settings. However, the published literature rarely documents the adaptation processes for psychological interventions to context or culture, including curriculum or implementation adaptations. Practical guidance for adapting PM+ to context while maintaining fidelity to core psychological elements is essential for mental health implementers to enable replication and scale. This paper describes the process of contextually adapting PM+ for implementation in Rwanda, Peru, Mexico and Malawi undertaken by the international nongovernmental organization Partners In Health. To our knowledge, this initiative is among the first to adapt PM+ for routine delivery across multiple public sector primary care and community settings in partnership with Ministries of Health. Lessons learned contribute to a broader understanding of effective processes for adapting low-intensity psychological interventions to real-world contexts.

RESUMEN

BACKGROUND: There is a growing literature in support of the effectiveness of task-shared mental health interventions in resource-limited settings globally. However, despite evidence that effect sizes are greater in research studies than actual care, the literature is sparse on the impact of such interventions as delivered in routine care. In this paper, we examine the clinical outcomes of routine depression care in a task-shared mental health system established in rural Haiti by the international health care organization Partners In Health, in collaboration with the Haitian Ministry of Health, following the 2010 earthquake. METHODS: For patients seeking depression care betw|een January 2016 and December 2019, we conducted mixed-effects longitudinal regression to quantify the effect of depression visit dose on symptoms, incorporating interaction effects to examine the relationship between baseline severity and dose. RESULTS: 306 patients attended 2052 visits. Each visit was associated with an average reduction of 1.11 in depression score (range 0-39), controlling for sex, age, and days in treatment (95% CI -1.478 to -0.91; p < 0.001). Patients with more severe symptoms experienced greater improvement as a function of visits (p = 0.04). Psychotherapy was provided less frequently and medication more often than expected for patients with moderate symptoms. CONCLUSIONS: Our findings support the potential positive impact of scaling up routine mental health services in low- and middle-income countries, despite greater than expected variability in service provision, as well as the importance of understanding potential barriers and facilitators to care as they occur in resource-limited settings.

RESUMEN

BACKGROUND: Collection of biologic samples from the nasal cavity and paranasal sinuses is of critical importance to the study of infectious or inflammatory conditions that affect both upper and lower airways. Numerous techniques for the study of ex-vivo samples exist, with specific applications, strengths, and weaknesses associated with each of them. In this compendium we summarize the available methods for collection of primary human samples and incorporate expert discussion of the pros, cons, and applications associated with each technique. METHODS: An expert panel containing members of the American Rhinologic Society's Research and Grants Committee compiled this educational reference. Rationale for use and the potential advantages and disadvantages are discussed. Research protocols and key references are enumerated. RESULTS: Sampling of the nasal cavity and paranasal sinuses can be achieved through a number of methods. Nonspecific sinonasal secretions may be collected via forced exhalation, nasal lavage, and nasal spray aspiration. Targeted collection of sinonasal secretions may be achieved via endoscopic placement of absorbent matrices. Nasal cytology or collection of superficial epithelium may be completed via brushing or scraping of endonasal structures. Collection of mucosal biopsies may be completed via sinonasal explant or full-thickness biopsy. CONCLUSION: Multiple sampling techniques are available to collect biologic samples from the sinonasal cavity. These techniques differ in their ease of application, reproducibility, sample yield, and utility for different sinonasal pathologies or research goals. An appreciation of the benefits and drawbacks of each approach will allow investigators to select the techniques most appropriate for achieving research objectives.

RESUMEN

OBJECTIVE: The catatonic syndrome ("catatonia") is characterized by motor and motivation dysregulation and is associated with a number of neuropsychiatric and medical disorders. It is recognizable in a variety of clinical settings. We present observations from the treatment of four individuals with catatonia in Haiti and Rwanda and introduce a treatment protocol for use in resource-limited settings. METHODS: Four patients from rural Haiti and Rwanda with clinical signs of catatonia and a positive screen using the Bush-Francis Catatonia Rating Scale were treated collaboratively by general physicians and mental health clinicians with either lorazepam or diazepam. Success in treatment was clinically assessed by complete remittance of catatonia symptoms. RESULTS: The four patients in this report exhibited a range of characteristic and recognizable signs of catatonia, including immobility/stupor, stereotypic movements, echophenomena, posturing, odd mannerisms, mutism and refusal to eat or drink. All four cases presented initially to rural outpatient general health services in resource-limited settings. In some cases, diagnostic uncertainty initially led to treatment with typical antipsychotics. In each case, proper identification and treatment of catatonia with benzodiazepines led to significant clinical improvement. CONCLUSION: Catatonia can be effectively and inexpensively treated in resource-limited settings. Identification and management of catatonia are critical for the health and safety of patients with this syndrome. Familiarity with the clinical features of catatonia is essential for health professionals working in any setting. To facilitate early recognition of this treatable disorder, catatonia should feature more prominently in global mental health discourse.

RESUMEN

Deaths to babies in their first 28 days of life now account for more than 40% of global under-5 child mortality. High neonatal mortality poses a significant barrier to achieving the child survival Millennium Development Goal. Surmounting the problem requires national-level political commitment, yet only a few nation-states have prioritised this issue. We compare Bolivia, Malawi and Nepal, three low-income countries with high neonatal mortality, with a view to understanding why countries prioritise or neglect the issue. The three have had markedly different trajectories since 2000: attention grew steadily in Nepal, stagnated then grew in Malawi and grew then stagnated in Bolivia. The comparison suggests three implications for proponents seeking to advance attention to neglected health issues in low-income countries: the value of (1) advancing solutions with demonstrated efficacy in low-resource settings, (2) building on existing and emerging national priorities and (3) developing a strong network of domestic and international allies. Such actions help policy communities to weather political storms and take advantage of policy windows.

RESUMEN

Bolivia is expected to achieve United Nations Millennium Development Goal Four, reducing under-five child mortality by two-thirds between 2021 and 2025. However, progress on child mortality reduction masks a disproportionately slow decline in newborn deaths during the 2000s. Bolivia's neonatal mortality problem emerged on the policy agenda in the mid-1990s and grew through 2004 in relationship to political commitments to international development goals and the support of a strong policy network. Network status declined later in the decade. This study draws upon a framework for analysing determinants of political priority for global health initiatives to understand the trajectory of newborn survival policy in Bolivia from the early 1990s. A process-tracing case study methodology is used, informed by interviews with 26 individuals with close knowledge of newborn survival policy in the country and extensive document analysis. The case of newborn survival in Bolivia highlights the significance of political commitments to international development goals, health policy network characteristics (cohesion, composition, status and key actor support) and political transitions and instability in shaping agenda status, especially decline-an understudied phenomenon considering the transitory nature of policy priorities. The study suggests that the sustainability of issue attention therefore become a focal point for health policy networks and analyses.

RESUMEN

Gorgonian corals possess many novel natural products that could potentially mediate coral-bacterial interactions. Since many bacteria use quorum sensing (QS) signals to facilitate colonization of host organisms, regulation of prokaryotic cell-to-cell communication may represent an important bacterial control mechanism. In the present study, we examined extracts of twelve species of Caribbean gorgonian corals, for mechanisms that regulate microbial colonization, such as antibacterial activity and QS regulatory activity. Ethanol extracts of gorgonians collected from Puerto Rico and the Florida Keys showed a range of both antibacterial and QS activities using a specific Pseudomonas aeruginosa QS reporter, sensitive to long chain AHLs and a short chain N-acylhomoserine lactones (AHL) biosensor, Chromobacterium violaceium. Overall, the gorgonian corals had higher antimicrobial activity against non-marine strains when compared to marine strains. Pseudopterogorgia americana, Pseusopterogorgia acerosa, and Pseudoplexuara flexuosa had the highest QS inhibitory effect. Interestingly, Pseudoplexuara porosa extracts stimulated QS activity with a striking 17-fold increase in signal. The stimulation of QS by P. porosa or other elements of the holobiont may encourage colonization or recruitment of specific microbial species. Overall, these results suggest the presence of novel stimulatory QS, inhibitory QS and bactericidal compounds in gorgonian corals. A better understanding of these compounds may reveal insight into coral-microbial ecology and whether a therapeutic potential exists.
