There are increasing calls to provide greenspace in urban areas, yet the ecological quality, as well as quantity, of greenspace is important. Short mown grassland designed for recreational use is the dominant form of urban greenspace in temperate regions but requires considerable maintenance and typically provides limited habitat value for most taxa. Alternatives are increasingly proposed, but the biodiversity potential of these is not well understood. In a replicated experiment across six public urban greenspaces we used nine different perennial meadow plantings to quantify the relative roles of floristic diversity and height of sown meadows on the richness and composition of three taxonomic groups – plants, invertebrates and soil microbes. We found that all meadow treatments were colonised by plant species not sown in the plots, suggesting that establishing sown meadows does not preclude further locally determined grassland development if management is appropriate. Colonising species were rarer in taller and more diverse plots, indicating competition may limit invasion rates. Urban meadow treatments contained invertebrate and microbial communities that differed from mown grassland. Invertebrate taxa responded to changes in both height and richness of meadow vegetation, but most orders were more abundant where vegetation height was longer than mown grassland. Order richness also increased in longer vegetation and Coleoptera family richness increased with plant diversity in summer. Microbial community composition seems sensitive to plant species composition at the soil surface (0–10 cm), but in deeper soils (11–20 cm) community variation was most responsive to plant height, with bacteria and fungi responding differently. In addition to improving local residents’ satisfaction, native perennial meadow plantings can produce biologically diverse grasslands that support richer and more abundant invertebrate communities, and restructured plant, invertebrate and soil microbial communities compared with short mown grassland. Our results suggest that diversification of urban greenspace by planting urban meadows in place of some mown amenity grassland is likely to generate substantial biodiversity benefits, with a mosaic of meadow types likely to maximise such benefits.

AbstractObjectivesTo evaluate the potential for long distance airborne transmission of SARS-CoV-2 in indoor community settings and to investigate factors that might influence transmission.DesignRapid systematic review and narrative synthesis.Data sourcesMedline, Embase, medRxiv, Arxiv, and WHO COVID-19 Research Database for studies published from 27 July 2020 to 19 January 2022; existing relevant rapid systematic review for studies published from 1 January 2020 to 27 July 2020; and citation analysis in Web of Science and Cocites.Eligibility criteria for study selectionObservational studies reporting on transmission events in indoor community (non-healthcare) settings in which long distance airborne transmission of SARS-CoV-2 was the most likely route. Studies such as those of household transmission where the main transmission route was likely to be close contact or fomite transmission were excluded.Data extraction and synthesisData extraction was done by one reviewer and independently checked by a second reviewer. Primary outcomes were SARS-CoV-2 infections through long distance airborne transmission (>2 m) and any modifying factors. Methodological quality of included studies was rated using the quality criteria checklist, and certainty of primary outcomes was determined using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. Narrative synthesis was themed by setting.Results22 reports relating to 18 studies were identified (methodological quality was high in three, medium in five, and low in 10); all the studies were outbreak investigations. Long distance airborne transmission was likely to have occurred for some or all transmission events in 16 studies and was unclear in two studies (GRADE: very low certainty). In the 16 studies, one or more factors plausibly increased the likelihood of long distance airborne transmission, particularly insufficient air replacement (very low certainty), directional air flow (very low certainty), and activities associated with increased emission of aerosols, such as singing or speaking loudly (very low certainty). In 13 studies, the primary cases were reported as being asymptomatic, presymptomatic, or around symptom onset at the time of transmission. Although some of the included studies were well conducted outbreak investigations, they remain at risk of bias owing to study design and do not always provide the level of detail needed to fully assess transmission routes.ConclusionThis rapid systematic review found evidence suggesting that long distance airborne transmission of SARS-CoV-2 might occur in indoor settings such as restaurants, workplaces, and venues for choirs, and identified factors such as insufficient air replacement that probably contributed to transmission. These results strengthen the need for mitigation measures in indoor settings, particularly the use of adequate ventilation.Systematic review registrationPROSPERO CRD42021236762.

In the fall of 2022, the Biden administration brought renewed attention to food insecurity and diet-related chronic disease by holding the first White House Conference on Hunger, Nutrition, and Health in more than 50years. The administration has also made climate change a key focus by rejoining the Paris Climate Agreement, investing in climate adaptation and resilience, and committing to cutting greenhouse gas (GHG) emissions 50% to 52% below 2005 levels by 2030.1 These actions appropriately prioritize the pressing public health threats posed by hunger, undernutrition, and climate change, but so far the administration has failed to recognize that these threats are closely interconnected. We cannot effectively nourish the population and prevent the irreversible environmental damages of climate change without making our food system more sustainable.2,3 To succeed in meeting these twin objectives, the administration must align its food and nutrition priorities with its climate priorities.

The vaginal ring (VR) is a female-initiated drug-delivery platform used for different indications, including HIV pre-exposure prophylaxis (PrEP). We conducted a systematic review of VR acceptability, values and preferences among women in low- and middle-income countries (LMIC) to inform further investment and/or guidance on VR use for HIV prevention. Following PRISMA guidelines, we used structured methods to search, screen, and extract data from randomized controlled trials (RCTs) and observational studies reporting quantitative outcomes of acceptability of the VR for any indication published 1/1970-2/2019 (PROSPERO: CRD42019122220). Of 1,110 records identified, 68 met inclusion criteria. Studies included women 15-50+ years from 25 LMIC for indications including HIV prevention, contraception, abnormal bleeding, and menopause. Overall VR acceptability was high (71-98% across RCTs; 62-100% across observational studies), with 80-100% continuation rates in RCTs and favorable ease of insertion (greater than 85%) and removal 89-99%). Users reported concerns about the VR getting lost in the body (8-43%), although actual expulsions and adverse events were generally infrequent. Most women disclosed use to partners, with some worrying about partner anger/violence. The VR was not felt during intercourse by 70-92% of users and 48-97% of partners. Acceptability improved over time both within studies (as women gained VR experience and worries diminished), and over chronological time (as the device was popularized). Women expressed preferences for accessible, long-acting, partner-approved methods that prevent both HIV and pregnancy, can be used without partner knowledge, and have no impact on sex and few side effects. This review was limited by a lack of standardization of acceptability measures and study heterogeneity. This systematic review suggests that most LMIC women users have a positive view of the VR that increases with familiarity of use; and, that many would consider the VR an acceptable future delivery device for HIV prevention or other indications.

Purpose In the past decade, there has been an increase in the development and use of oral anti-cancer medications (OAMs), especially for breast cancer–the most prevalent cancer in women. However, adherence rates for OAMs are often suboptimal, leading to lower survival rate, increased risk of recurrence, and higher healthcare costs. Our goal was to identify potentially modifiable psychosocial facilitators and barriers that may be targeted to increase OAM adherence for breast cancer patients. Methods We systematically searched PubMed for studies published in the U.S. by June 15, 2016 that addressed the following: (1) OAMs for breast cancer; (2) medication adherence; and (3) at least one psychosocial aspect of adherence. Results Of the 1752 papers screened, 21 articles were included and analyzed. The most commonly reported motivators for adherence are patient-provider relationships ( n  = 11 studied, 82% reported significant association) and positive views and beliefs of medication ( n  = 9 studied, 89% reported significant association). We also identified consistent evidence of the impact of depression and emotions, perception of illness, concern of side effects, self-efficacy in medication management and decision making, knowledge of medication, and social support on OAM adherence. Conclusions Compared to traditional demographic, system, and clinical-related factors that have been well documented in the literature but are not easily changed, these cognitive, psychological, and interpersonal factors are more amendable via intervention and therefore could generate greater benefit in improving patient compliance and health outcomes. As OAMs shift treatment administration responsibility onto patients, continuous provider communication and education on illness and regimen are the keys to supporting patients’ medication behavior.

Lewy body disorders are heterogeneous neurological conditions defined by intracellular inclusions composed of misshapen α-synuclein protein aggregates. Although α-synuclein aggregates are only one component of inclusions and not strictly coupled to neurodegeneration, evidence suggests they seed the propagation of Lewy pathology within and across cells. Genetic mutations, genomic multiplications, and sequence polymorphisms of the gene encoding α-synuclein are also causally linked to Lewy body disease. In nonfamilial cases of Lewy body disease, the disease trigger remains unidentified but may range from industrial/agricultural toxicants and natural sources of poisons to microbial pathogens. Perhaps due to these peripheral exposures, Lewy inclusions appear at early disease stages in brain regions connected with cranial nerves I and X, which interface with inhaled and ingested environmental elements in the nasal or gastrointestinal cavities. Irrespective of its identity, a stealthy disease trigger most likely shifts soluble α-synuclein (directly or indirectly) into insoluble, cross-β-sheet aggregates. Indeed, β-sheet-rich self-replicating α-synuclein multimers reside in patient plasma, cerebrospinal fluid, and other tissues, and can be subjected to α-synuclein seed amplification assays. Thus, clinicians should be able to capitalize on α-synuclein seed amplification assays to stratify patients into potential responders versus non-responders in future clinical trials of α-synuclein targeted therapies. Here, we briefly review the current understanding of α-synuclein in Lewy body disease and speculate on pathophysiological processes underlying the potential transmission of α-synucleinopathy across the neuraxis.

Lewy body disorders are heterogeneous neurological conditions defined by intracellular inclusions composed of misshapen [alpha]-synuclein protein aggregates. Although [alpha]-synuclein aggregates are only one component of inclusions and not strictly coupled to neurodegeneration, evidence suggests they seed the propagation of Lewy pathology within and across cells. Genetic mutations, genomic multiplications, and sequence polymorphisms of the gene encoding [alpha]-synuclein are also causally linked to Lewy body disease.

Urban parks provide mental and physical health benefits by mitigating harmful environmental exposures, including heat and air pollution. Urban parks often cluster in more privileged neighborhoods. Health burdens from harmful environmental exposures are highest in less privileged ones. Using Trust for Public Land’s ParkServe database of publicly accessible parks, sociodemographic data from the American Communities Survey, and high-resolution satellite-imagery, we compared park size and environmental conditions by neighborhood privilege. To ascertain privilege, we calculated the combined race and income Index of Concentration at the Extremes (ICE) in each census tract of the 24 most populous urban areas in the United States. We found that parks in the least privileged neighborhoods (i.e., bottom quartile of ICE) had on average 1.24 ppb higher concentrations of nitrogen dioxide (NO 2 ) and 1.00 μg/m 3 higher fine particulate matter (PM 2.5 ) than parks in the most privileged neighborhoods (top ICE quartile). Parks in the most privileged neighborhoods were significantly larger and cooler in more than half of the included urban areas and significantly greener in over a third. Our results reveal disparities in the environmental conditions, and thus expected health benefits, between parks in the most and least privileged neighborhoods in the most populous urban areas in the United States.

Background There has been increasing recognition that certain vulnerable populations in the United States of America struggle to meet their menstruation-related needs, including people experiencing homelessness. Media and policy attention on this subject has focused on the provision of free menstrual products to vulnerable populations, including a New York City legislative bill, which guarantees access to menstrual products for Department of Homeless Services shelter residents (Intros 1123-A). Methods This qualitative study explored the challenges people experiencing homelessness in New York City face in accessing menstrual products. Data collection was conducted from June to August 2019 and included: Semi-structured key informant interviews with staff from relevant government agencies and homeless service providers (n = 15), and semi-structured in-depth interviews with individuals with experience living on the street and in shelters (n = 22). Data were analysed using thematic analysis. Results Key themes that emerged included: (1) insufficient and inconsistent access to menstrual products; (2) systemic challenges to providing menstrual products; and (3) creative solutions to promote access to menstrual products. Both shelter- and street-living individuals reported significant barriers to accessing menstrual products. While both populations struggle, those in shelters were more likely to be able to purchase menstrual products or access free products at their shelter, while those living on the streets were more likely to have to resort to panhandling, theft, or using makeshift materials in place of menstrual products. Across both populations, individuals described barriers to accessing free products at shelters and service providers, primarily due to distribution systems that rely on gatekeepers to provide a few pads or tampons at a time, sometimes of inadequate quality and only upon request. Shelters and service providers also described challenges providing these products, including inconsistent supply. Conclusion These findings highlight the critical importance of expanding and improving initiatives seeking to provide access to menstrual products for vulnerable populations. Despite policy level efforts to support menstrual product access, individuals experiencing homelessness in New York City, whether living in shelters or on the street, are often not able to access the menstrual products that they need to manage their monthly menstrual flow.

ObjectiveRace remains a significant predictor of poor outcomes in women with gynecologic cancer and minority patients consistently report worse quality of life during cancer treatment. Disparities between patients in strength of social and emotional supports may contribute to these outcomes. This study’s objective was to describe the racial differences in patient reported outcomes of women being evaluated or treated for a gynecologic malignancy at a large tertiary cancer hospital.MethodsIn this prospective cohort study, all patients presenting for care at a tertiary care gynecologic oncology clinic between January 2018 and September 2019 were evaluated for inclusion. All patients were administered validated patient reported outcome measure questionnaires at serial visits. Demographic data was gathered including self-reported race. Patients were characterized as White, Black, Asian, Hispanic/Latino, or Other. Patient reported outcomes were compared between respondents of different races using linear and logistic regression.ResultsBetween January 2018 to September 2019, 2022 patients with a known race completed questionnaires. Of these patients, 86.7% were White, 4.3% Black, and 4.9% Hispanic/Latino and 58.7% had a known cancer diagnosis. Non-White patients were significantly less likely to complete questionnaires (p<0.001). Non-White patients reported significantly lower levels of emotional support on all questions (Patient-Reported Outcomes Measurement Information System (PROMIS) emotional support: Q1 p<0.001, Q2 p<0.001, Q3 p=0.013, Q4 p=0.002), and lower overall emotional (p=0.005) and instrumental (p=0.005) support scores when compared with White patients. Hispanic/Latino patients reported the lowest levels of emotional and instrumental support and more cognitive (p=0.043) and financial (p=0.040) difficulties associated with treatment. Black women reported having less support with chores while sick (p=0.014) and being less likely to have someone to talk to (p=0.013).ConclusionsSignificant differences exist in patient reported outcomes between women of different racial backgrounds. Hispanic/Latino and Black women have less support during gynecologic cancer evaluation and treatment as compared with White women.
