“…Participants’ GPS data points over their 14-day device wear period were used to generate a time-weighted activity space surface using a 200-m-bandwidth KDE function. The time-weighted activity space was then multiplied by the walkability index, comprising intersection density, residential density, and land use mix, to produce the average dynamic walkability exposure variable [ 68 ].…”

Active travel (AT) provides an opportunity to alleviate the physical inactivity and climate crises contributing to the global chronic disease burden, including cardiovascular diseases (CVD). Though AT shows promising links to reduced CVD risk, prior studies relied on self-reported AT assessment. In the present study, device-measured and self-reported AT were compared across population subgroups and relationships with CVD risk biomarkers were evaluated for both measures. The study recruited an ethnically diverse sample (N = 602, mean age 59 years, 42% Hispanic/Latino ethnicity) from neighborhoods that varied by walkability and food access. AT was assessed using concurrently collected accelerometer and GPS data and self-report data from a validated survey. Relationships with body mass index (BMI), triglycerides, high-density lipoprotein (HDL) cholesterol, blood pressure (BP), and moderate-to-vigorous physical activity (MVPA) were modeled using multivariable linear regression. Devices captured more AT than did self-report. We found differences in AT measures by population subgroups, including race, ethnicity, education, income, vehicle access, and walkability. Men had more accelerometer-measured MVPA, though women self-reported more daily minutes. Both device and survey AT measures were positively associated with total accelerometer-measured MVPA, though the relationship was stronger with device-measured AT. Device-measured AT was associated with lower BMI. No other CVD risk biomarker was associated with either AT measure. No effect modification by Hispanic/Latino ethnicity was detected. Further studies with device-based measures are warranted to better understand the relationship between AT and cardiovascular health.

There is a growing literature on the association between neighborhood contexts and cancer survivorship. To understand the current trends and the gaps in the literature, we aimed to answer the following questions: To what degree, and how, has cancer survivorship research accounted for neighborhood-level effects? What neighborhood metrics have been used to operationalize neighborhood factors? To what degree do the neighborhood level metrics considered in cancer research reflect neighborhood development as identified in the Leadership for Energy and Environmental Design for Neighborhood Development (LEED-ND) guidelines? We first conducted a review guided by PRISMA extension for scoping review of the extant literature on neighborhood effects and cancer survivorship outcomes from January 2000 to January 2021. Second, we categorized the studied neighborhood metrics under six main themes. Third, we assessed the findings based on the LEED-ND guidelines to identify the most relevant neighborhood metrics in association with areas of focus in cancer survivorship care and research. The search results were scoped to 291 relevant peer-reviewed journal articles. Results show that survivorship disparities, primary care, and weight management are the main themes in the literature. Additionally, most articles rely on neighborhood SES as the primary (or only) examined neighborhood level metric. We argue that the expansion of interdisciplinary research to include neighborhood metrics endorsed by current paradigms in salutogenic urban design can enhance the understanding of the role of socioecological context in survivorship care and outcomes.

“…Geospatial distribution of sheep and goats exposed to T. gondii Small ruminants are intermediate hosts of T. gondii, which are highly susceptible to T. gondii and, chronically infectious for life. It is believed that the parasite is a major cause of abortion and neonatal mortality in sheep and goats, resulting in economic loss [13][14]. Furthermore, consumption of raw or undercooked meat from these animals has been regarded as a major route of T. gondii transmission to humans, especially in countries and regions where mutton and beef is regularly eaten [15].…”

“…It has been reported that isolating T. gondii from seropositive cattle were often unsuccessful, however Dubey JP [18] showed that viable tissue cysts can remain in cattle for up to 1 191 days. Hence, the contaminated cattle and yaks may be an important source for T. gondii transmitted to other animals and humans in China [14]. The geospatial distribution of toxoplasmosis in cattle and yaks in China is shown in Fig.…”

Background: Toxoplasma gondii (T. gondii) is an important foodborne zoonotic parasite with respect to abortion, intracranial calcifications, congenital hydrocephalus, retinochoroiditis, and toxoplasmic encephalitis in severely immunosuppressed individuals. Undercooked/raw meat containing cyst-stage bradyzoites and contaminated pets are presumed to constitute a major source of human infection. Although many seroprevalence studies have been performed in humans and different animal species in China, data on the geospatial distribution of toxoplasmosis prevalence are extremely scarce. The aim of the present study was to investigate the prevalence and geospatial distribution of toxoplasmosis among livestock, pets and humans in China using geographic information system (GIS) for the prevention and control of toxoplasmosis.Methods: This article is based on the data from PubMed, China National Knowledge Infrastructure (CNKI) and Baidu Scholar databases from 1984 up to 2020 regarding prevalence data of toxoplasmosis among livestock (sheep and goats, swines, cattle and yaks), pets (cats, dogs) and humans in China. Geospatial distribution of the prevalence of toxoplasmosis in these hosts was performed using the GIS visualization techniques.Results: Analysis revealed wide geospatial variation of toxoplasmosis in China. The estimated pooled seroprevalence of T. gondii was ranged from 3.98% to 43.02% among sheep and goats in China, 0.75% to 30.34% in cattle and yaks, 10.45% to 66.47% in swines, 2.50% to 60.00% in cats, 0.56% to 27.65% in dogs, and 0.72% to 23.41% in humans. The higher seroprevalences of T. gondii were observed in districts Chongqing, Zhejiang and Beijing in sheep and goats. The infection rates of T. gondii in cattle and yaks were higher in districts Guizhou, Zhejiang and Chongqing. Moreover, the swines from districts Chongqing and Guizhou were also most severely infected with T. gondii. In cats, districts Shanxi, Hebei and Yunnan had higher seroprevalences of T. gondii and, the infections among dogs were higher in districts Yunnan and Hebei as well. Furthermore, higher infection pressure of T. gondii exists in districts Taiwan and Tibet in humans.Conclusion: The present study indicated that the infection with T. gondii was widely spread in China, with a wide range of variation. The investigation of T. gondii infection in livestock, pets and humans can be useful for assessing T. gondii environmental contamination and the risk for public health. Certain measures can be taken to prevent the prevalence of T. gondii infection in China, such as strengthening the management of livestock farms, keeping the barn clean, preventing feline excreta from polluting environment, using filtered water or water boiling, wearing gloves when handling raw meat and improving the practice of good hand hygiene.
