OBJECTIVE: To assess burn injury knowledge and its predictors among reproductive-age women attending an urban and a semi-rural hospital in Northwest Nigeria DESIGN: A descriptive cross-sectional study SETTING: It was conducted in the general and paediatric outpatient clinics of Aminu Kano Teaching Hospital in Kano (urban setting) and the general outpatient, paediatric outpatient and antenatal clinics of Federal Medical Centre Birnin Kudu (semi-rural setting).
METHODS: In 2021, 362 women aged 18-44 years were randomly selected from clinic attendees over six weeks. Of them, 217 were from the urban hospital. Data regarding their sociodemographic characteristics and knowledge of burn injuries was collected using a pretested, semi-structured interviewer-administered questionnaire.
METHODS: Knowledge of burn injuries RESULTS: About 83.4 %, 77.1 % and 77.6 % of respondents had adequate general, primary prevention and overall knowledge of burn injuries, respectively. Their mean overall knowledge score was 18.6 out of 24, but only 55.5 % had adequate first-aid knowledge. The study sites did not significantly differ in burns first-aid, prevention and overall knowledge scores. However, urban respondents were more ignorant about the cause of burns and knew that burn injuries could be fatal. More semi-rural respondents knew that flames and chemicals cause burn injuries. Predictors of overall knowledge were age, educational level, number of children in their household, previously seeing a burn-injured child, and primary source of burns-related information.
CONCLUSIONS: The proportion of respondents with adequate overall burn injury knowledge was high; however, knowledge gaps exist among them. Overall, their first-aid knowledge was relatively low. The urban and semi-rural respondents had no significant differences in first-aid, prevention, or overall knowledge of burn injuries. However, knowledge of the causes of burns and burn complications differed between the urban and semi-rural study locations. Therefore, the clinical settings of this study present opportunities for similar burn-related educational interventions.

This study investigates the relationship between temporal changes in temperatures characterizing local urban heat islands (UHIs) and heat-related illnesses (HRIs) in seven major cities of California. UHIs, which are a phenomenon that arises in the presence of impervious surfaces or the lack of green spaces exacerbate the effects of extreme heat events, can be measured longitudinally using satellite products. The two objectives of this study were: (1) to identify temperature trends in local temperatures to characterize UHIs across zip code tabulation areas (ZCTAs) in the seven observed cities over a 22-year period and (2) to use propensity score and inverse probability weighting to achieve exchangeability between different types of ZCTAs and assess the difference in hospital admissions recorded as HRIs attributable to temporal changes in UHIs. We use monthly land surface temperature data derived from MODIS Terra imagery from the summer months (June-September) from 2000 to 2022. We categorized ZCTAs (into three groups) based on their monthly land surface temperature trends. Of the 216 ZCTAs included in this study, the summertime land surface temperature trends of 43 decreased, while 161 remained unchanged, and 12 increased. Los Angeles had the greatest number of decreased ZCTAs, San Diego and San Jose had the highest number of increased ZCTAs. To analyze the number of monthly HRI attributable to changes in UHI, we used inverse probability of treatment weighting to analyze the difference in HRI between the years of 2006 and 2017 which were two major extreme heat events over the entire State. We observed an average reduction of 3.2 (95 % CI: 0.5; 5.9) HRIs per month and per ZCTAs in decreased neighborhoods as compared to unchanged. This study emphasizes the importance of urban climate adaptation strategies to mitigate the intensity and prevalence of UHIs to reduce health risks related to heat.

OBJECTIVE: The impact of urbanization on plant evolution, particularly the evolution of reproductive traits, remains largely unknown. In this study, we aimed to investigate the consequences of urbanization on the reproductive traits of Portulaca oleracea in the Kantō region of Japan. Portulaca oleracea has a unique cleistogamous reproductive system, which consists of genetically determined chasmogamous (open, CH) and cleistogamous (closed, CL) plants.
METHODS: We collected seeds of P. oleracea from ten populations in rural areas and ten populations in urban areas. In a common garden experiment, we recorded the type of flowers (CH or CL), reproductive phenology and seed production.
RESULTS: All individuals produced either CH or CL flowers, allowing us to classify them as either CH or CL plants. We observed a significant difference in the prevalence of CH and CL plants between rural and urban populations: the number of CH plants was generally low and was particularly low among urban individuals. Compared to CH plants, CL plants showed earlier phenology and produced heavier seeds, which is consistent with stress avoidance in response to heat and drought stress conditions in urban areas.
CONCLUSIONS: Our findings suggest that urbanization may drive an evolutionary change in the cleistogamous reproductive system of P. oleracea. CL plants with earlier phenology and larger seeds might be better adapted to urban environments, where they are subjected to harsh heat and drought stress.

UNASSIGNED: Although studies often report the prevalence of obesity, community-based studies reporting the incidence of overweight or obesity in India are scarce. Such incidence data are crucial for improving projections about the future burden of obesity.
UNASSIGNED: A non-concurrent follow-up study was done in 2015 in urban Vellore, Tamil Nadu, among two groups of women aged 30-40 years, with body mass index (BMI) <25 kg/m2 (normal) and BMI ≥25 kg/m2 (overweight/obese) in 2012, to assess changes in BMI. The sampling frame consisted of 473 women: 209 women with BMI <25 kg/m2, and 264 women with BMI ≥25 kg/m2, who were part of a cross-sectional survey in 2012. A randomly selected list of 370 women (80% of the original cohort) was used to trace the women. Measurements at follow-up included weight, height, dietary and other risk factors.
UNASSIGNED: Of 370 women, 170 (45.9%) were followed up at the end of three years, which included 82 with BMI <25 kg/m2 and 88 with BMI >25 kg/m2. The incidence of overweight (BMI ≥25 kg/m2) in three years, was 29.2% (24/82), among women with a normal BMI (<25 kg/m2) in 2012. Among the 88 women who were overweight/obese in 2012, there was no regression to normal BMI within the three years of follow-up. There was an association between the incidence of overweight and the intake of carbohydrates (adjusted odds ratios (AORs): 3, 95% confidence interval (CI): 1.04 to 8.63) and protein intake (AOR: 20.0, 95% CI:2.5 to 158.3).
UNASSIGNED: This study found an incidence of nearly one-third (29.2%) of developing high BMI (≥25.0 kg/m2) in 30-40-year-old urban women from Vellore, implying a rapid increase in overweight and obesity among young women.

Extensive green roofs provide for many ecosystem services in urban environments. The efficacy of these services is influenced by the vegetation structure. Despite their key role in plant performance and productivity, but also their contribution to nitrogen fixation or carbon sequestration, green roof microbial communities have received little attention so far. No study included a spatiotemporal aspect to investigate the core microbiota residing in the substrates of extensive green roofs, although these key taxa are hypothesized to be amongst the most ecologically important taxa. Here, we identified the core microbiota residing in extensive green roof substrates and investigated whether microbial community composition is affected by the vegetation that is planted on extensive green roofs. Eleven green roofs from three different cities in Flanders (Belgium), planted either with a mixture of grasses, wildflowers and succulents (Sedum spp.; Sedum-herbs-grasses roofs) or solely species of Sedum (Sedum-moss roofs), were seasonally sampled to investigate prokaryotic and fungal communities via metabarcoding. Identifying the key microbial taxa revealed that most taxa are dominant phylotypes in soils worldwide. Many bacterial core taxa are capable of nitrogen fixation, and most fungal key taxa are stress-tolerant saprotrophs, endophytes, or both. Considering that soil microbes adapted to the local edaphic conditions have been found to improve plant fitness, further investigation of the core microbiome is warranted to determine the extent to which these stress-tolerant microbes are beneficial for the vegetational layer. Although Sedum-herbs-grasses roofs contained more plant species than Sedum-moss roofs, we observed no discriminant microbial communities between both roof types, likely due to sharing the same substrate textures and the vegetational layers that became more similar throughout time. Future studies are recommended to comprehensively characterize the vegetational layer and composition to examine the primary drivers of microbial community assembly processes.

OBJECTIVE: Diet-related disease is rising, disproportionately affecting minority communities in which small food retail stores swamp supermarkets. Barriers to healthy food access were exacerbated by the pandemic. We examined the following: (1) individual- and household-level factors in a sample of Baltimore community members who regularly shop at corner stores and (2) how these factors are associated with indicators of dietary quality.
METHODS: Cross-sectional data were collected using an online survey to capture sociodemographics, anthropometrics, and food sourcing, spending, and consumption patterns. Concurrent quantitative and qualitative analyses were conducted in Stata 18 and ATLAS.ti.
METHODS: This study was set in Baltimore, Maryland, USA.
METHODS: The participants included adults (n = 127) living or working in Baltimore who identified as regular customers of their neighborhood corner store.
RESULTS: The respondents were majority Black and low-income, with a high prevalence of food insecurity (62.2%) and overweight/obesity (66.9%). Most (82.76%) shopped in their neighborhood corner store weekly. One-third (33.4%) of beverage calories were attributed to sugar-sweetened beverages, and few met the recommended servings for fruits and vegetables or fiber (27.2% and 10.4%, respectively). Being Black and not owning a home were associated with lower beverage and fiber intake, and not owning a home was also associated with lower fruit and vegetable intake. Food insecurity was associated with higher beverage intake, while WIC enrollment was associated with higher fruit and vegetable and fiber intakes. Open-ended responses contextualized post-pandemic food sourcing and consumption in this setting.
CONCLUSIONS: This paper helps characterize the consumers of a complex urban food system. The findings will inform future strategies for consumer-engaged improvement of local food environments.

BACKGROUND: Missing and Murdered Indigenous People is a historic and contemporary issue that has gained national attention. In 2021, homicide was the eighth leading cause of death among American Indian/Alaska Native (AIAN) persons aged between 1 and 54 years old, and homicide is the sixth leading cause of death among all AIAN males aged 1-54 years old.
OBJECTIVE: These data will build knowledge around AIAN homicides and to identify circumstances that can aid in comprehensive Missing and Murdered Indigenous People prevention efforts.
METHODS: AIAN homicide data came from Centers for Disease Control and Prevention\'s National Violent Death Reporting System, a state/jurisdiction-based surveillance system that collects detailed information about characteristics and circumstances of violent deaths. We examined data from 2003 to 2020 (all available years) from participating states/jurisdictions. We also assessed sociodemographic characteristics of victims and suspects, incident characteristics and differences across dichotomised urban/rural status. The study was conducted in 2022.
RESULTS: The National Violent Death Reporting System provided data on 2959 AIAN homicides from 2003 to 2020 (54.2% urban and 45.8% rural). Significant differences based on the two locations included type of weapon used, the location of the injury, race of the primary suspect, the victim\'s relationship to the suspect and select circumstances precipitating the homicide including crimes precipitating the homicide and homicides stemming from intimate partner violence.
RESULTS: These findings provide crucial information to strengthen public health efforts for prevention.

Cognitive skills, such as innovative problem-solving, are hypothesized to aid animals in urban environments. However, the significance of innovation in wild populations, and its expression across individuals and socio-ecological conditions, is poorly understood. To identify how and when innovation arises in urban-dwelling species, we used advanced technologies and new testing and analytical methods to evaluate innovative problem-solving abilities of wild raccoons (Procyon lotor). We deployed multi-compartment puzzle boxes with either one or multiple solution types and identified raccoons using radio frequency identification. Raccoons solved these novel extractive foraging tasks, and their success was influenced by age and exploratory diversity. Successful raccoons always discovered multiple different solution types, highlighting flexible problem-solving. Using a unique, comparative sequence analysis approach, we found that variation in raccoon solving techniques was greater between individuals than within individuals, and this self-similarity intensified during times of competition. Finally, the inclusion of an easier solution in the multi-solution trials enabled previously unsuccessful raccoons to bootstrap their learning and successfully open multiple difficult solutions. Our study suggests that innovative problem-solving is probably influenced by many factors and has provided novel field and analytical methods, as well as new insights on the socio-ecological dynamics of urban populations.

Background: Effective healthcare clinician communication is a key component of quality palliative and end-of-life (PEOL) care. However, communication may be hampered when clinicians are not comfortable initiating these conversations with patients and their families. Clinicians working in rural areas report several barriers to providing palliative care. This study examined the relationship between rural and urban clinicians\' reported familiarity with their patients and families end-of-life, their reported comfort in initiating PEOL conversations, and their PEOL care knowledge. Method: This study used a cross-sectional design to examine the relationships between rural and urban clinicians\' familiarity, their comfort in PEOL communication, and their PEOL care knowledge. Results: N = 548 rural and urban clinicians participated. Rural clinicians reported greater familiarity, more PEOL knowledge, and more comfort with PEOL communication. Multiple regression analyses of PEOL knowledge showed significant associations in knowledge with older clinicians (P < 0.01) and additional palliative care training (P < 0.01); comfort in PEOL communication had significant associations with more palliative care training (P < 0.01) and opportunities to provide palliative care (P < 0.01). Conclusion: The concept of familiarity is highly complex and poorly understood in relation to PEOL care in both rural and urban settings. Future research is needed to explore how additional training in PEOL care and clinician reported familiarity positively impact patient outcomes by increasing the number of advance directives completed and followed and improved documentation of advance care planning.

STS theories of biocapital conceptualize how biomedical knowledge and capital form together. Though these formations of biocapital often are located in large urban centers, few scholars have attended to how they are transforming urban spaces and places. In this paper we argue that the twinned technological development of cells and cities concentrates economic and symbolic capital and sets in motion contentious practices we name urban biopolitics. We draw on archival research and a nearly decade-long ethnography of the expansion of biomedical campuses in a major American city to show how the speculative logics of land development and biomedical innovation become bound together in a process we describe as speculative revitalization. We examine how the logics of speculative revitalization imagine a future in which cities and biomedicine produce wealth and health harmoniously together. However, in practice-as buildings of new biomedical urban campuses get built-the dreams of billionaire philanthrocapitalists to create global cities clash with the plans of biomedical researchers to create global health. We document the reproduction of stratified and racialized biomedical exclusions that result while also highlighting the unlikely opportunities for creating alliances committed to creating equitable biomedical research and healthcare in urban communities.
