RESUMEN

Body size is key to many life-history processes, including reproduction. Across species, climate change and other stressors have caused reductions in the body size to which animals can grow, called asymptotic size, with consequences for demography. A reduction in mean asymptotic length was documented for critically endangered North Atlantic right whales, in parallel with declines in health and vital rates resulting from human activities and environmental changes. Here, we tested whether smaller body size was associated with lower reproductive output, using a state-space model for individual health, survival and reproduction that quantifies the mechanistic links between these processes. Body size (as represented by the cube of length) was strongly associated with a female's calving probability at each reproductive opportunity. This relationship explained 62% of the variation in calving among reproductive females, along with their decreasing health (20%). The effects of decreasing mean body size on reproductive performance are another concerning indication of the worsening prospects for this species and many others affected by environmental change, requiring a focus of conservation and management interventions on improving conditions that affect reproduction as well as reducing mortality.

RESUMEN

Chronic pain is prevalent and often under-addressed among people with HIV and people who use drugs, likely compounding the stress of discrimination in healthcare, and self-medicating along with its associated overdose risk or other problematic coping. Due to challenges in treating pain and HIV in the context of substance use, collaborative, patient-centered patient-provider engagement (PCE) may be particularly important for mitigating the impact of pain on illicit drug use and promoting sustained recovery. We examined whether PCE with primary care provider (PCE-PCP) mediated the effects of pain, discrimination, and denial of prescription pain medication on later substance use for pain among a sample of 331 predominately African Americans with HIV and a drug use history in Baltimore, Maryland, USA. Baseline pain level was directly associated with a higher chance of substance use for pain at 12 months (Standardized Coefficient = 0.26, p < .01). Indirect paths were observed from baseline healthcare discrimination (Standardized Coefficient = 0.05, 95% CI=[0.01, 0.13]) and pain medication denial (Standardized Coefficient = 0.06, 95% CI=[0.01, 0.14]) to a higher chance of substance use for pain at 12 months. Effects of prior discrimination and pain medication denial on later self-medication were mediated through worse PCE-PCP at 6 months. Results underscore the importance of PCE interpersonal skills and integrative care models in addressing mistreatment in healthcare and substance use in this population. An integrated approach for treating pain and substance use disorders concurrently with HIV and other comorbidities is much needed. Interventions should target individuals at multiple risks of discriminations and healthcare professionals to promote PCE.

RESUMEN

Vulnerable persons living with HIV (PLWH) are at high risk of cognitive impairment and challenges accessing quality social support in later life. Impaired verbal fluency (VF), a cognitive domain linked to HIV, could impede social support associated with health and well-being for already vulnerable PLWH. We examined the structure of social support, using latent class analysis, and the associations among quantity, specific forms and quality of social support and VF among PLWH. Participants enrolled in the BEACON study (n = 383) completed the Controlled Oral Word Association test (COWAT) and a social support network inventory. Latent class analysis with count variables was used to determine the number of classes of PLWH based on their social network characteristics. The majority of PLWH were male (61.4%) and African American (85.9%). Two distinct latent classes, with a major distinction in the number of network members who were female, knew participants' HIV status and HIV medication usage. Fewer support network members (ß = -.13, p < 0.01), greater negative interactions (ß = -.16, p < 0.01), and less positive interactions with network members (ß = .15, p < 0.05) were significantly associated with lower COWAT scores. Comprehensive screening of high-risk PLWH and early intervention with those with cognitive impairment are important for addressing social support needs.

RESUMEN

BACKGROUND: The experience of living with cancer is marked by suffering and loss, which creates a need for healing. Understanding what healing means to patients and how clinicians can play a role in the healing process is essential to holistic cancer care. OBJECTIVE: The aim of this study was to explore the perspectives of cancer patients on the meaning and experiences of healing and the qualities of a clinician and the clinician-patient relationship that are healing. METHODS: A qualitative study was conducted using semi-structured interviews with 14 cancer patients. Participants were asked about their illness experience, definition of healing, qualities of a healer, and relationships with clinicians that were healing. Interview transcripts were coded, and qualitative analysis was conducted to identify major themes. RESULTS: Participants defined the nature of healing as comprising aspects of physical, mental, emotional, and spiritual well-being. Participants described healing as alleviating pain and symptoms; promoting mental strength, emotional comfort, and spiritual connection; restoring and adapting to losses; and improving quality of life. The qualities of a clinician that contributed to a healing relationship included listening, empathy and compassion, understanding patients' values and goals, and caring for the patient as a whole person. CONCLUSION: Participants viewed healing as physical, psychosocial, and spiritual in nature and an important part of their cancer experience with an emphasis on quality of life. Clinicians played an important role beyond treating the cancer by helping in the healing process through their humanistic qualities and holistic approach to patient care.

RESUMEN

Adherence to antiretroviral therapy (ART) is vital for reducing racial and gender disparities in morbidity and mortality among people living with HIV/AIDS (PLWH). Little research attention has been given to aspects of family functioning affecting ART adherence among PLWH vulnerable to disparities. Data were from n = 313 participants (93% African American) in the BEACON study, which recruited injection-drug-using PLWH on ART. Using factor analysis and longitudinal structural equation modeling, we found that current substance use and negative family conflict tactics (i.e., non-negotiation) predicted PLWH's lower probability of ART adherence at 12-month follow-up; and greater HIV disclosure to support network members predicted a higher probability of adherence. These findings suggest the importance of family and other support network members in this vulnerable population's ART adherence. Social network-focused interventions promoting prosocial response to conflict and negotiation skills are important for improving vulnerable PLWH's HIV outcomes and reducing health disparities.

RESUMEN

Whales are now largely protected from direct harvest, leading to partial recoveries in many previously depleted species.1 However, most populations remain far below their historical abundances and incidental human impacts, especially vessel strikes and entanglement in fishing gear, are increasingly recognized as key threats.2 In addition, climate-driven changes to prey dynamics are impacting the seasonal foraging grounds of many baleen whales.2 In many cases these impacts result directly in mortality. But it is less clear how widespread and increasing sub-lethal impacts are affecting life history, individual fitness, and population viability. We evaluated changes in body lengths of North Atlantic right whales (NARW) using aerial photogrammetry measurements collected from crewed aircraft and remotely operated drones over a 20-year period (Figure 1). NARW have been monitored consistently since the 1980s and have been declining in abundance since 2011 due primarily to deaths associated with entanglements in active fishing gear and vessel strikes.3 High rates of sub-lethal injuries and individual-level information on age, size and observed entanglements make this an ideal population to evaluate the effects that these widespread stressors may have on individual fitness. We find that entanglements in fishing gear are associated with shorter whales, and that body lengths have been decreasing since 1981. Arrested growth may lead to reduced reproductive success4,5 and increased probability of lethal gear entanglements.6 These results show that sub-lethal stressors threaten the recoveries of vulnerable whale populations even in the absence of direct harvest.

RESUMEN

BACKGROUND: Alcohol outlets have been associated with various forms of injury and may contribute to neighborhood disparities in drug overdose. Few studies have examined the associations between alcohol outlets and drug overdose. This study investigated whether alcohol outlets were associated with the neighborhood drug overdose rate and whether the sale of drug paraphernalia contributes to this association. METHODS: A cross-sectional ecological spatial analysis was conducted within census block groups in Baltimore City (n = 653). Outcomes were counts of EMS calls for any drug overdose in 2015 (n = 3,856). Exposures of interest were counts of alcohol outlets licensed for off-premise and on-premise consumption and the proportion of off-premise outlets selling drug paraphernalia (e.g., blunt wrappers, baggies, pipes). Negative binomial regression was used to assess the relationship between outlet count and overdose rate, and if paraphernalia sales altered this relationship, controlling for other neighborhood factors. Spatial autocorrelation was assessed and regression inference adjusted accordingly. RESULTS: Each additional off-premise alcohol outlet was associated with a 16.6% increase in the neighborhood overdose rate (IRR=1.17, 95%CI=(1.11, 1.23)), adjusted for other neighborhood variables. On-premise alcohol outlets were not significantly associated with overdose rate when adjusting for off-premise alcohol outlets (IRR=1.01, 95% CI=(0.97, 1.06)). The proportion of off-premise outlets that sold drug paraphernalia was negatively associated with overdose rate (IRR=0.55, 95% CI=(0.41, 0.74)) and did not alter the relationship between off-premise outlets and overdose. CONCLUSION: This study provides preliminary public health evidence for informing policy decisions about alcohol outlet licensing and zoning. Alcohol outlets could be potential community partners for harm reduction strategies such as health communication in identifying overdose symptoms or Good Samaritan Laws.

RESUMEN

AIMS AND OBJECTIVE: Advance care planning (ACP) is the communication process of documenting future healthcare preferences in case patients are unable to make healthcare decisions for themselves. Research suggests ACP discussions among persons living with HIV (PLHIV) are infrequent overall and may differ by gender and/or race. BACKGROUND: Previous literature has displayed that African Americans are less likely than other racial groups to use advanced care planning, palliative care or hospice, but does not conclusively account for ACP among PLHIV. African American PLHIV rely on informal care that may be differ by gender and represents an important pathway to increase ACP. DESIGN: The study was mixed methods and observational. METHODS: Participants completed self-report surveys (N = 311) and were interviewed (n = 11). Poisson regression (quantitative) and grounded theory analyses (qualitative) were implemented, using COREQ checklist principles to ensure study rigor. RESULTS: Less than half had discussed ACP (41.2%; N = 267). More ACP knowledge predicted 76% lower likelihood of ACP discussions among women. Men who spent more time caregiving in a given week were nearly 3 times more likely to discuss ACP than men who spent less time caregiving. Women were more likely than men to be caregivers and were also expected to serve in that role more than men, which was qualitatively described as 'being a woman'. CONCLUSIONS: The present study is one of few studies exploring ACP among caregivers in African American populations hardest hit by HIV. Results suggest that ACP skill building and education are critical for African Americans living with HIV to promote ACP discussions with their caregivers. Knowledge about ACP topics was low overall even when healthcare had recently been accessed. Support reciprocity and gender-specific communication skill building may facilitate ACP in African American HIV informal caregiving relationships. RELEVANCE TO CLINICAL PRACTICE: Results underscore the need for ACP education which includes healthcare providers and caregivers, given African Americans' preference for life-sustaining treatments at end-of-life. ACP is crucial now more than ever, as COVID-19 complicates care for older adults with HIV at high risk of complications.

RESUMEN

Whaling has decimated North Atlantic right whales Eubalaena glacialis (NARW) since the 11th century and southern right whales E. australis (SRW) since the 19th century. Today, NARWs are Critically Endangered and decreasing, whereas SRWs are recovering. We review NARW health assessment literature, NARW Consortium databases, and efforts and limitations to monitor individual and species health, survival, and fecundity. Photographs are used to track individual movement and external signs of health such as evidence of vessel and entanglement trauma. Post-mortem examinations establish cause of death and determine organ pathology. Photogrammetry is used to assess growth rates and body condition. Samples of blow, skin, blubber, baleen and feces quantify hormones that provide information on stress, reproduction, and nutrition, identify microbiome changes, and assess evidence of infection. We also discuss models of the population consequences of multiple stressors, including the connection between human activities (e.g. entanglement) and health. Lethal and sublethal vessel and entanglement trauma have been identified as major threats to the species. There is a clear and immediate need for expanding trauma reduction measures. Beyond these major concerns, further study is needed to evaluate the impact of other stressors, such as pathogens, microbiome changes, and algal and industrial toxins, on NARW reproductive success and health. Current and new health assessment tools should be developed and used to monitor the effectiveness of management measures and will help determine whether they are sufficient for a substantive species recovery.

RESUMEN

BACKGROUND: Persons living with HIV (PLWH) are living into old age with more complex care needs that non-PLWH. Promoting quality of life should include advance care planning (ACP) education, particularly among African Americans. We explored faith/spirituality-related correlates of interest in a future quality of life program among African American PLWH. METHODS: Data were from the AFFIRM study. Participants were recruited from an HIV clinic and completed surveys, interviews, and focus groups. Quantitative analyses included Logistic regression. Qualitative data were coded using grounded theory. RESULTS: Nearly half of participants had less than a high school education (47.9%), and roughly 90% had heard of at least one ACP-related topic (86.6%; N = 315). Qualitative themes related to quality of life and faith/spirituality were: (1) Coping with life challenges; (2) Motivation to improve health for loved ones; and (3) Support programs for people with HIV (N = 39). Satisfaction with religion/spirituality was associated with greater interest in a future program (p < .05); discussing ACP before getting sick was associated with less interest (p < .05). CONCLUSIONS/PRACTICE IMPLICATIONS: Prioritizing skill-building and grounding in spirituality with input from faith leaders can reduce ACP inequities and improve health outcomes among African Americans.

RESUMEN

Literature on health-related quality of life (HRQOL) has focused on people living with chronic conditions, with less attention given to HRQOL among informal caregivers. We used cross-sectional dyadic data from both care recipients (CR) living with HIV and the person they identified as their primary informal (unpaid) caregiver (CG) to identify psychosocial and caregiving relationship factors (including, CG role ambivalence and caregiving-related stress) associated with CG HRQOL. We conducted confirmatory factor analysis and structural equation modeling testing. The results highlight interdependent effects of the CG-CR relationship and reveal pathways whereby relationship interactions positively and negatively impact CGs' HRQOL. Affiliative stigma, CG-CR communication, CRs' reciprocity of support and other psychosocial factors indirectly and differentially affected physical and mental HRQOL through effects on secondary stress and role ambivalence. Dyad-focused intervention on interpersonal communication and support exchange may improve HRQOL and resilience of CGs of vulnerable people living with HIV.


RESUMEN: La literatura sobre calidad de vida relacionada con la salud (CVRS) se ha centrado en las personas que viven con enfermedades crónicas, con menos atención a la CVRS entre los cuidadores informales. Utilizamos datos diádicos transversales de recibidores de cuidado (RC) que viven con VIH y de la persona que identificaron como su principal cuidador informal (no remunerado) (CI) para identificar los factores psicosociales y en la relación de cuidado (incluyendo la ambivalencia del rol de CI y del estrés) asociado con calidad de vida. Realizamos análisis factoriales confirmatorios y pruebas de modelación de ecuaciones estructurales. Los resultados demostraron los efectos interdependientes de la relación entre el cuidador y el recibidor de cuidado y revelan cómo las interacciones de la relación impactan la calidad de vida de los cuidadores. El estigma, la comunicación en la relación, la reciprocidad de apoyo de los recibidores de cuidado y otros factores psicosociales afectaron indirecta y diferencialmente la calidad de vida física y mental a través de los efectos sobre el estrés secundario y la ambivalencia de roles. Las intervenciones diádicas centradas en la comunicación interpersonal y la facilitación de apoyo pueden mejorar la calidad de vida y la capacidad de recuperación de los cuidadores de las personas vulnerables que viven con el VIH.

RESUMEN

OBJECTIVE: To understand the needs of Emergency Medical Service (EMS) providers caring for substance users in an urban setting. DESIGN: Qualitative interviews with EMS providers regarding perceptions of substance users and treatment programs. SETTING: Baltimore City. PARTICIPANTS: Twenty-two Baltimore City Fire Department EMS providers. INTERVENTIONS: Semistructured in-depth interviews were conducted with 22 EMS providers. Topics included experiences caring for substance-using patients and attitudes about local harm reduction approaches. MAIN OUTCOME MEASURE: Providers were asked their views on receiving training to deliver a brief motivational intervention to encourage patients to enter drug treatment. Interviews were transcribed and analyzed using constant comparison. RESULTS: Participants were mostly Male (68.2 percent), White (66.6 percent), and had Advanced Life Skills training (90.9 percent). Mean experience was 8.7 years. Many providers described EMS misusers as mostly male and middle-aged, although there were variations in substance use patterns among all races and income levels. Most stated that repeated care provision to a small number of substance-users negatively impacted care quality. Provider demands included departmental policies and resource limitations. Many expressed willingness to deliver motivational messages to substance-using patients to consider drug treatment. Other stated that behavioral interventions were beyond their job duties and most reported having little-to-no knowledge of local treatment programs. CONCLUSIONS: EMS providers may be uniquely positioned to deliver substance use treatment messages to substance users. This could be a life- and cost-saving improvement to EMS in Baltimore City with incentivized training. More research is needed to inform opioid use preparedness in urban settings, which remain at the center of the opioid epidemic.

RESUMEN

CONTEXT: Little attention has been given to social environmental factors associated with advance care planning (ACP) among African Americans or people living with advanced HIV (PLHIV). OBJECTIVES: The present study aimed to identify support network factors that affect the likelihood of naming a decision-maker and of talking to family/friends and doctors about ACP among vulnerable PLHIV. METHODS: PLHIV were recruited from a large urban HIV clinic. A social support network inventory was used to calculate number of persons available for various types of support. Characteristics of network members were also collected. Multivariable logistic regression models were fit to examine associations between social network factors and ACP discussion, adjusting for age, sex, education, and total number of network members. RESULTS: The sample (N = 370) was mostly African American (95%), male (56%), and 48% had less than a high school education. Almost half the sample (48%) had talked to their family/friends or doctor about ACP, and 34% had named a medical decision-maker. Adjusted analysis revealed that talking about ACP with family/friends was associated with female sex and a larger closer support network who provided health information and physical assistance. Talking to doctors about ACP was associated with larger support networks who provided physical assistance but lower numbers from whom emotional support was received. Naming a decision-maker was associated with greater numbers of network members who provided emotional support, health information, and medication adherence reminders. CONCLUSION: The findings revealed aspects of family/support network structures and caregiving function associated with ACP in a population with often vital yet vulnerable networks.

RESUMEN

CONTEXT: In the era of effective antiretroviral therapy, persons living with HIV/AIDS (PLWHA) are living longer, transforming HIV from a universally fatal disease to a serious chronic illness, warranting discussions between patients and their loved ones about advance care planning (ACP). Evidence is needed on factors associated with patients' likelihood to discuss ACP with loved ones. OBJECTIVES: To further characterize factors associated with successful ACP in PLWHAs with their loved ones, we examined associations between patients having ACP discussions with the need for assistance with personal care, chronic pain, life satisfaction, prior family disagreements over health care decisions, sex, age, and interference in daily routines due to memory problems. METHODS: Data were from the Affirm Care study (N = 370), which examined social and environmental factors associated with health outcomes among PLWHAs and their informal caregivers. RESULTS: Slightly more than half of respondents discussed ACP with loved ones (57%). In adjusted analysis, higher levels of chronic pain (odds ratio [OR] = 2.09, P = 0.045), needing assistance with personal care (OR = 1.63, P = 0.023), greater life satisfaction (OR = 1.02, P = 0.002), prior family arguments over health care decisions (OR = 2.80, P < 0.001), and female sex (OR = 2.22, P = 0.001) were associated with higher odds of discussing ACP with loved ones, whereas age, drug use, education level, depression, and memory problems were nonsignificant. CONCLUSION: These results suggest that interventions to increase ACP among PLWHAs and their loved ones should target males. The findings also suggest PLWHAs with chronic pain, the need for assistance with personal care, and those with a history of prior family arguments over health care decisions may be primed for ACP.

RESUMEN

Animal movement plays a fundamental role in the ecology of migratory species, and understanding migration patterns is required for effective management. To evaluate intrinsic and environmental factors associated with probabilities of endangered North Atlantic right whales Eubalaena glacialis migrating to a wintering ground off the southeastern United States (SEUS), we applied a multistate temporary emigration capture-recapture model to 22 years of photo-identification data. Migration probabilities for juveniles were generally higher yet more variable than those for adults, and non-calving adult females were the least likely group to migrate. The highest migration probabilities for juveniles and adult males coincided with years of relatively high calving rates, following years of higher prey availability in a fall feeding ground. Right whale migration to the SEUS can be classified as condition-dependent partial migration, which includes skipped breeding partial migration for reproductive females, and is likely influenced by tradeoffs among ecological factors such as reproductive costs and foraging opportunities that vary across individuals and time. The high variability in migration reported in this study provides insight into the ecological drivers of migration but presents challenges to right whale monitoring and conservation strategies.

RESUMEN

OBJECTIVES: The purpose of this study was to investigate the contribution of neighbourhood disorder around alcohol outlets to pedestrian injury risk. METHODS: A spatial analysis was conducted on census block groups in Baltimore City. Data included pedestrian injury EMS records from 1 January 2014 to 15 April 2015 (n=858), off-premise alcohol outlet locations for 2014 (n=693) and neighbourhood disorder indicators and demographics. Negative binomial regression models were used to determine the relationship between alcohol outlet count and pedestrian injuries at the block group level, controlling for other neighbourhood factors. Attributable risk was calculated by comparing the total population count per census block group to the injured pedestrian count. RESULTS: Each one-unit increase in the number of alcohol outlets was associated with a 14.2% (95% CI 1.099 to 1.192, P<0.001) increase in the RR of neighbourhood pedestrian injury, adjusting for traffic volume, pedestrian volume, population density, per cent of vacant lots and median household income. The attributable risk was 10.4% (95% CI 7.7 to 12.7) or 88 extra injuries. Vacant lots was the only significant neighbourhood disorder indicator in the final adjusted model (RR=1.016, 95% CI 1.007 to 1.026, P=0.003). Vacant lots have not been previously investigated as possible risk factors for pedestrian injury. CONCLUSIONS: This study identifies modifiable risk factors for pedestrian injury previously unexplored in the literature and may provide evidence for alcohol control strategies (eg, liquor store licencing, zoning and enforcement).

RESUMEN

BACKGROUND: Alcohol outlet density has been associated with increased pedestrian injury risk. It is unclear whether this is because alcohol outlets are located in dense retail areas with heavy pedestrian traffic or whether alcohol outlets contribute a unique neighborhood risk. We aimed to compare the pedestrian injury rate around alcohol outlets to the rate around other, similar retail outlets that do not sell alcohol. METHODS: A spatial analysis was conducted on census block groups in Baltimore City. Data included pedestrian injury emergency medical services (EMS) records from January 1, 2014 to April 15, 2015 (n = 848); locations of alcohol outlets licensed for off-premise (n = 726) and on-premise consumption (n = 531); and corner (n = 398) and convenience stores (n = 192) that do not sell alcohol. Negative binomial regression was used to determine the relationship between retail outlet count and pedestrian injuries, controlling for key confounding variables. Spatial autocorrelation was also assessed and variable selection adjusted accordingly. RESULTS: Each additional off-premise alcohol outlet was associated with a 12.3% increase in the rate of neighborhood pedestrian injury when controlling for convenience and corner stores and other confounders (incidence rate ratio [IRR] = 1.123, 95% confidence interval [CI] = 1.065, 1.184, p < 0.001). The attributable risk was 4.9% (95% CI = 0.3, 8.9) or 41 additional injuries. On-premise alcohol outlets were not significant predictors of neighborhood pedestrian injury rate in multivariable models (IRR = 0.972, 95% CI = 0.940, 1.004, p = 0.194). CONCLUSIONS: Off-premise alcohol outlets are associated with pedestrian injury rate, even when controlling for other types of retail outlets. Findings reinforce the importance of alcohol outlets in understanding neighborhood pedestrian injury risk and may provide evidence for informing policy on liquor store licensing, zoning, and enforcement.

RESUMEN

CONTEXT: Advance care planning rates remain low, especially among people who are HIV positive, disadvantaged, and African American. Although advance care planning can be a sensitive topic for clinicians and patients to discuss, health values clarification can be an important initial step. OBJECTIVES: The purpose of the study was to explore health values of African Americans living with HIV/AIDS and to examine correlates of these values. METHODS: Data were from the first 325 participants in the AFFIRM Care study, which enrolled adults living with HIV/AIDS in Baltimore, Maryland, who had histories of illicit drug use. Respondents were asked whether (yes/no) they thought any of six health states would be worse than death: severe unremitting pain, total dependency on others, irreversible coma, being on mechanical ventilation, nursing home residence, and severe dementia. Latent class analysis was used to group individuals by their pattern of responses, interpretable as preference for aggressive (life-sustaining) or nonaggressive (palliative) end-of-life care. Latent class regression analysis was used to examine associations between class membership and background, health status, and social variables. RESULTS: We found statistical support for a three-class latent class analysis model: 1) the nonaggressive treatment class, comprising 43% of cases, in which members perceived that every state was worse than death; 2) the aggressive treatment class, comprising 33% of cases, in which members perceived that none of the states was worse than death; and 3) the mixed class (24% of cases), in which members perceived that only four of the six states were worse than death. CONCLUSION: Three-quarters of participant response patterns had clear preferences for treatment decisions. Further research is needed to ensure inclusion of end-of-life scenarios relevant to this population.

RESUMEN

OBJECTIVE: Understanding pedestrian injury trends at the local level is essential for program planning and allocation of funds for urban planning and improvement. Because we hypothesize that local injury trends differ from national trends in significant and meaningful ways, we investigated citywide pedestrian injury trends to assess injury risk among nationally identified risk groups, as well as identify risk groups and locations specific to Baltimore City. METHODS: Pedestrian injury data, obtained from the Baltimore City Fire Department, were gathered through emergency medical services (EMS) records collected from January 1 to December 31, 2014. Locations of pedestrian injuries were geocoded and mapped. Pearson's chi-square test of independence was used to investigate differences in injury severity level across risk groups. Pedestrian injury rates by age group, gender, and race were compared to national rates. RESULTS: A total of 699 pedestrians were involved in motor vehicle crashes in 2014-an average of 2 EMS transports each day. The distribution of injuries throughout the city did not coincide with population or income distributions, indicating that there was not a consistent correlation between areas of concentrated population or concentrated poverty and areas of concentrated pedestrian injury. Twenty percent (n = 138) of all injuries occurred among children age ≤14, and 22% (n = 73) of severe injuries occurred among young children. The rate of injury in this age group was 5 times the national rate (Incident Rate Ratio [IRR] = 4.81, 95% confidence interval [CI], [4.05, 5.71]). Injury rates for adults ≥65 were less than the national average. CONCLUSIONS: As the urban landscape and associated pedestrian behavior transform, continued investigation of local pedestrian injury trends and evolving public health prevention strategies is necessary to ensure pedestrian safety.

RESUMEN

Among persons living with HIV/AIDS (PLHIV), approximately two-thirds report moderate to severe pain. Chronic pain can negatively affect PLHIVs' health behaviors and outcomes by interfering with their reciprocity (mutual exchange) of support in their caregiving relationships, which has been found to be associated with PLHIVs' antiretroviral adherence and viral suppression. Data were longitudinal (baseline, 6- and 12-month follow-up) from 383 PLHIV who were formerly or currently using drugs. Utilizing a longitudinal lagged fixed effects structural equation model, we found that never having pain in the past 6 months was predictive of increased reciprocity of support. Sub-analyses by care relationship type revealed never having pain was a significant predictor of greater reciprocity for sexual partner caregiving dyads, but not for kin or friend caregiving dyads. Our study emphasizes the importance of pain management in quality caregiving relationships characterized by reciprocity, which has consistently been found to be associated with stronger, more supportive caregiving relationships and better quality of life. Our findings suggest the importance of pain management intervention for improving reciprocity between vulnerable PLHIVs and their primary caregivers, especially between PLHIVs and caregivers who are current or former sexual partners.
