RESUMO
Narratives are a means of making sense of disasters and crises. The humanitarian sector communicates stories widely, encompassing representations of peoples and events. Such communications have been critiqued for misrepresenting and/or silencing the root causes of disasters and crises, depoliticising them. What has not been researched is how such communications represent disasters and crises in Indigenous settings. This is important because processes such as colonisation are often at the origin but are typically masked in communications. A narrative analysis of humanitarian communications is employed here to identify and characterise narratives in humanitarian communications involving Indigenous Peoples. Narratives differ based upon how the humanitarians who produce them think that disasters and crises should be governed. The paper concludes that humanitarian communications reflect more about the relationship between the international humanitarian community and its audience than reality, and underlines that narratives mask global processes that link audiences of humanitarian communications with Indigenous Peoples.

This mixed-methods, exploratory study examined why women living with HIV (WLHIV) stay in intimate partner violence (IPV) relationships and what helps end IPV in their lives. WLHIV (n = 108) who experienced IPV and were patients at two HIV primary care clinics in San Francisco completed quantitative surveys; 15 participants also completed a qualitative interview. Qualitative data showed HIV stigma was the most cited reason for staying in an IPV relationship, followed by substance use, and then by themes of attachment insecurity. Quantitative data indicated that most participants accessed HIV services and rated them as more helpful than other community resources to end IPV in their lives. Enduring attachment relationships with HIV medical and social service providers and their attachment-enhancing actions and attributes were critical to participants addressing IPV and coping with HIV stigma. This study highlights the important role that HIV providers and clinics can play in addressing IPV among WLHIV.

Climate change adaptation responses are being developed and delivered in many parts of the world in the absence of detailed knowledge of their effects on public health. Here we present the results of a systematic review of peer-reviewed literature reporting the effects on health of climate change adaptation responses in low- and middle-income countries (LMICs). The review used the 'Global Adaptation Mapping Initiative' database (comprising 1682 publications related to climate change adaptation responses) that was constructed through systematic literature searches in Scopus, Web of Science and Google Scholar (2013-2020). For this study, further screening was performed to identify studies from LMICs reporting the effects on human health of climate change adaptation responses. Studies were categorised by study design and data were extracted on geographic region, population under investigation, type of adaptation response and reported health effects. The review identified 99 studies (1117 reported outcomes), reporting evidence from 66 LMICs. Only two studies were ex ante formal evaluations of climate change adaptation responses. Papers reported adaptation responses related to flooding, rainfall, drought and extreme heat, predominantly through behaviour change, and infrastructural and technological improvements. Reported (direct and intermediate) health outcomes included reduction in infectious disease incidence, improved access to water/sanitation and improved food security. All-cause mortality was rarely reported, and no papers were identified reporting on maternal and child health. Reported maladaptations were predominantly related to widening of inequalities and unforeseen co-harms. Reporting and publication-bias seems likely with only 3.5% of all 1117 health outcomes reported to be negative. Our review identified some evidence that climate change adaptation responses may have benefits for human health but the overall paucity of evidence is concerning and represents a major missed opportunity for learning. There is an urgent need for greater focus on the funding, design, evaluation and standardised reporting of the effects on health of climate change adaptation responses to enable evidence-based policy action.
RESUMO
This article contributes to the field of mixed methods by introducing a new method for eliciting participant perspectives of the quantitative results of randomized controlled trials. Participants are rarely asked to interpret trial results, obscuring potentially valuable information about why a trial either succeeds or fails. We introduce a unique method called visual participatory analysis and discuss the insights gained in its use as part of a trial to prevent risk and reduce the prevalence of diabetes in Bangladesh. Findings highlight benefits such as elucidating contextualized explanations for null results and identifying causal mechanisms, as well as challenges around communicating randomized controlled trial methodologies to lay audiences. We conclude that visual participatory analysis is a valuable method to use after a trial.
RESUMO
Proper blood vessel formation requires coordinated changes in endothelial cell polarity and rearrangement of cell-cell junctions to form a functional lumen. One important regulator of cell polarity is the centrosome, which acts as a microtubule organizing center. Excess centrosomes perturb aspects of endothelial cell polarity linked to migration, but whether centrosome number influences apical-basal polarity and cell-cell junctions is unknown. Here, we show that excess centrosomes alter the apical-basal polarity of endothelial cells in angiogenic sprouts and disrupt endothelial cell-cell adherens junctions. Endothelial cells with excess centrosomes had narrower lumens in a 3D sprouting angiogenesis model, and zebrafish intersegmental vessels had reduced perfusion following centrosome overduplication. These results indicate that endothelial cell centrosome number regulates proper lumenization downstream of effects on apical-basal polarity and cell-cell junctions. Endothelial cells with excess centrosomes are prevalent in tumor vessels, suggesting how centrosomes may contribute to tumor vessel dysfunction.

BACKGROUND: Trauma is increasingly recognized as a near-universal experience among women living with HIV (WLHIV) and a key contributor to HIV acquisition, morbidity, and mortality. METHODS: We present data from the baseline analysis of a planned intervention trial of the impact of trauma-informed health care on physical, behavioral, and social health outcomes of WLHIV in one clinic, with a particular focus on quality of life and viral suppression. Data were collected through interviewer-administered surveys and electronic health record data abstraction. RESULTS: Among 104 WLHIV, 97.1% of participants reported having experienced lifetime trauma, and participants had experienced on average 4.2 out of 10 Adverse Childhood Experiences. WLHIV with more lifetime trauma were significantly more likely to report post-traumatic stress disorder, depression, and anxiety symptoms; significantly more likely to report potentially harmful alcohol and drug use; and had a significantly poorer quality of life. In addition, women who had experienced more lifetime trauma were significantly less likely to report being on and adhering to HIV medications, although trauma was not significantly associated with having an undetectable HIV viral load. CONCLUSIONS: These data suggest that trauma is associated with much of the morbidity and mortality experienced by WLHIV. The results of this study support the implementation and study of trauma-informed approaches to health care for WLHIV.

BACKGROUND: Trauma-informed health care for women living with human immunodeficiency virus (HIV) attends not only to HIV treatment, but also to the many common physical and emotional health consequences of trauma. One principle of providing trauma-informed care is the acknowledgement that working with a population that has experienced extensive trauma affects the team members who care for them in the clinic, as well as the interactions between those team members. METHODS: To understand the needs of one primary health care team, we conducted in-depth interviews with 21 providers, staff, and collaborators who provide care to patients within the clinic. We used symbolic interaction and grounded theory methods to examine how interactions unfold within the clinic and how they are influenced by trauma. RESULTS: The clinic team serves a highly traumatized and vulnerable population. Within this context, interactions between clinic staff unfold and trauma surfaces, and power dynamics play out along the lines of professional hierarchy. Although power differences cause tension within the clinic, professional hierarchy also serves as an important division of labor in times of medical crises. CONCLUSIONS: Clinic power dynamics may be influenced to improve the care environment for patients, and to realize a more effective and satisfying trauma-informed health care clinic for both patients and staff.

BACKGROUND: Randomised controlled trials (RCTs) are widely used for establishing evidence of the effectiveness of interventions, yet public health interventions are often complex, posing specific challenges for RCTs. Although there is increasing recognition that qualitative methods can and should be integrated into RCTs, few frameworks and practical guidance highlight which qualitative methods should be integrated and for what purposes. As a result, qualitative methods are often poorly or haphazardly integrated into existing trials, and researchers rely heavily on interviews and focus group discussions. To improve current practice, we propose a framework for innovative qualitative research methods that can help address the challenges of RCTs for complex public health interventions. METHODS: We used a stepped approach to develop a practical framework for researchers. This consisted of (1) a systematic review of the innovative qualitative methods mentioned in the health literature, (2) in-depth interviews with 23 academics from different methodological backgrounds working on RCTs of public health interventions in 11 different countries, and (3) a framework development and group consensus-building process. RESULTS: The findings are presented in accordance with the CONSORT (Consolidated Standards of Reporting Trials) Statement categories for ease of use. We identify the main challenges of RCTs for public health interventions alongside each of the CONSORT categories, and potential innovative qualitative methods that overcome each challenge are listed as part of a Framework for the Integration of Innovative Qualitative Methods into RCTs of Complex Health Interventions. Innovative qualitative methods described in the interviews include rapid ethnographic appraisals, document analysis, diary methods, interactive voice responses and short message service, community mapping, spiral walks, pair interviews and visual participatory analysis. CONCLUSIONS: The findings of this study point to the usefulness of observational and participatory methods for trials of complex public health interventions, offering a novel contribution to the broader literature about the need for mixed methods approaches. Integrating a diverse toolkit of qualitative methods can enable appropriate adjustments to the intervention or process (or both) of data collection during RCTs, which in turn can create more sustainable and effective interventions. However, such integration will require a cultural shift towards the adoption of method-neutral research approaches, transdisciplinary collaborations, and publishing regimes.

Qualitative methods are underutilized in health intervention evaluation, and overshadowed by the importance placed on randomized controlled trials (RCTs). This Commentary describes how innovative qualitative methods are being used as part of RCTs, drawing on articles included in a special issue of Qualitative Health Research on this topic. The articles' insights and a review of innovative qualitative methods described in trial protocols highlights a lack of attention to structural inequalities as a causal mechanism for understanding human behavior. We situate this gap within some well-known constraints of RCT methodologies, and a discussion of alternative RCT approaches that hold promise for bringing qualitative methods center stage in intervention evaluation, including adaptive designs, pragmatic trials, and realist RCTs. To address the power hierarchies of health evaluation research, however, we argue that a fundamental shift needs to take place away from a focus on RCTs and toward studies of health interventions.

Transgender women living with HIV experience high rates of substance use, violence, and post-traumatic stress disorder (PTSD). Seeking Safety is a manualized, present-focused, cognitive-behavioral therapy program designed to address co-occurring substance use and PTSD. Seeking Safety has evidence of efficacy in a variety of populations but had not been evaluated specifically with people living with HIV or transgender women. We pilot-tested a 12-session Seeking Safety program with a group of transgender women living with HIV who reported substance use and a history of violence. Seven transgender women living with HIV were recruited from two HIV primary care clinics in San Francisco and completed pre- and post-intervention assessments. Participants attended an average of 8 of the 12 sessions. Mean scores for all three outcome measures improved: PTSD symptom scores declined 17.5%, alcoholism screening scores declined 23.9%, and drug abuse screening scores declined 68.8%, on average. Despite the small sample, this pilot study showed Seeking Safety to be a promising intervention among transgender women living with HIV. The findings are encouraging and justify larger studies of Seeking Safety among transgender women and other people living with HIV who experience high rates of substance use and PTSD.

BACKGROUND: Resistin-like molecule alpha or found in inflammatory zone protein (Fizz1) is increased in pulmonary epithelial cells and also in limited amounts by other lung cells during various lung injuries and fibrosis. However, the direct role of Fizz1 produced in the pulmonary epithelium has not been determined. METHODS: Fizz1 Transgenic mice (CCSP/Fizz1) were generated that overexpress Fizz1 in the lung epithelium under the control of a doxycycline (Dox) inducible lung epithelial cell specific promoter Scgb1a1 (Clara cell secretory protein, CCSP). Histology and FACS analysis of lung cells were used to identify the direct effects of Fizz1 in the transgenic mice (Dox treated) when compared with control (CCSP/-) mice. Intratracheal bleomycin sulfate or silica in saline and saline alone were used to study the role of Fizz1 during bleomycin- and silica-induced pulmonary fibrosis in CCSP/Fizz1 and CCSP/- mice. Weight change, pulmonary inflammation, and fibrosis were assessed 10 days post bleomycin or 28 days post silica challenge. RESULTS: When CCSP/Fizz1 mice were fed Dox food, elevated Fizz1 protein was detected in lung homogenates by western blot. Lungs of mice in which Fizz1 was induced in the epithelium contained increased lung cells staining for CD11c and F4/80 by FACS analysis consistent with increased dendritic cells however, no changes were observed in the percentage of interstitial macrophages compared to CCSP/- controls. No significant changes were found in the lung histology of CCSP/Fizz1 mice after up to 8 weeks of overexpression compared to CCSP/- controls. Overexpression of Fizz1 prior to challenge or following challenge with bleomycin or silica did not significantly alter airway inflammation or fibrosis compared to control mice. CONCLUSIONS: The current study demonstrates that epithelial cell derived Fizz1 is sufficient to increase the bone-marrow derived dendritic cells in the lungs, but it is not sufficient to cause lung fibrosis or alter chemical or particle-induced fibrosis.

Low-income women of color who are HIV positive and living in violent relationships are at significant risk for stigma and problems with attachment security. This article explores the ways in which these women may experience internalized stigma from incorporating society's negative views of HIV and domestic violence. It also addresses the ways in which insecure attachment may develop or intensify in this population through violence in their adult intimate relationships and/or living with a life threatening illness. A model of medical and psychosocial care utilized at the Women's HIV Program at the University of California San Francisco is offered as an intervention to reduce stigma and enhance healthy attachment. Clinical examples demonstrate how this system of medical and psychosocial care can help women in this situation establish stability and improve their lives despite the intense challenges they face.

C3H/HeJ mice develop an increase in terminal air space area detectable by postnatal d 14 that persists into adulthood compared with strain-matched controls (C3H/SnJ, C3H/OuJ). Morphometric quantification revealed a 50% increase in terminal air space area by postnatal d 14 and a 2.3-fold increase by 2 mo of age in C3H/HeJ mice. Bacteriologic cultures obtained from the left lung on postnatal d 7 revealed > 100 colony-forming units (CFU)/left lung of predominantly Gram-negative bacteria (GNB) (Escherichia coli and Proteus mirabilis) in 13 of the 14 C3H/HeJ mice compared with 0 of 12 controls demonstrating colonization of the developing lung in C3H/HeJ mice. An approximately threefold increase in macrophages from bronchoalveolar lavage, threefold increases in matrix metalloproteinase 12 (MMP-12) mRNA and protein levels and elevated levels of proinflammatory cytokines monocyte chemoattractant protein (MCP-1) and keratinocyte-derived cytokine (KC) were also found. P. mirabilis obtained from lung cultures in C3H/HeJ mice induced nuclear factor-kappaB (NF-kappaB) activation in human embryonic kidney 293 (HEK 293) cells transfected with TLR5. In C3H/HeJ mice lacking TLR4 signaling, bacterial colonization is associated with chronic inflammation and permanent changes in lung morphology.
