Large-scale determinants of street tree growth rates across an urban environment.

Urban street trees offer cities critical environmental and social benefits. In New York City (NYC), a decadal census of every street tree is conducted to help understand and manage the urban forest. However, it has previously been impossible to analyze growth of an individual tree because of uncertainty in tree location.

Identifying patterns of reported findings on long-term cardiac complications of COVID-19: a systematic review and meta-analysis.

Introduction: Prior reviews synthesized findings of studies on long-term cardiac complications of COVID-19. However, the reporting and methodological quality of these studies has not been systematically evaluated. Here, we conducted a systematic review and meta-analysis on long-term cardiac complications of COVID-19 and examined patterns of reported findings by study quality and characteristics.

Predicting fine-scale daily NO over Mexico City using an ensemble modeling approach.

In recent years, there has been growing interest in developing air pollution prediction models to reduce exposure measurement error in epidemiologic studies. However, efforts for localized, fine-scale prediction models have been predominantly focused in the United States and Europe. Furthermore, the availability of new satellite instruments such as the TROPOsopheric Monitoring Instrument (TROPOMI) provides novel opportunities for modeling efforts.

Exploring Relevant Time Windows in the Association Between PM2.5 Exposure and Amyotrophic Lateral Sclerosis: A Case-Control Study in Denmark.

Studies suggest a link between particulate matter less than or equal to 2.5 μm in diameter (PM2.5) and amyotrophic lateral sclerosis (ALS), but to our knowledge critical exposure windows have not been examined.

Fournier's gangrene with retroperitoneal extension in an immunocompetent patient.

A male patient in his 80s presented with the classic signs of Fournier's gangrene. At his initial debridement, an unusual florid involvement of the right cord was noted requiring a right inguinal orchidectomy in addition to extensive debridement. Although he subsequently stabilised in the intensive care unit, his inflammatory markers were noted to uptrend again requiring a relook procedure which revealed evidence of progressive necrosis in the right inguinal region.

Long-term cardiac symptoms following COVID-19: a systematic review and meta-analysis.

Background: There is growing body of literature on the long-term cardiac symptoms following COVID-19. We conducted a systematic review and meta-analysis to synthesize and evaluate related evidence to inform clinical management and future studies.

Methods: We searched two preprint and seven peer-reviewed article databases from January 1, 2020 to January 8, 2022 for studies investigating cardiac symptoms that persisted for at least 4 weeks among individuals who survived COVID-19.

Short-term exposure to ozone and cause-specific mortality risks and thresholds in China: Evidence from nationally representative data, 2013-2018.

Background: Ambient ozone pollution is steadily increasing and becoming a major environmental risk factor contributing to the global disease burden. Although the association between short-term ozone exposure and mortality has been widely studied, results are mostly reported on deaths from non-accidental or total cardiopulmonary disease rather than a spectrum of causes. In particular, a knowledge gap still exists for the potential thresholds in mortality risks.

Traffic-related PM and its specific constituents on circulatory mortality: A nationwide modelling study in China.

Background: Short-term fine particulate matter (PM) exposure and increased circulatory mortality have been well documented. However, there are inconsistent findings on mortality effects of traffic-related pollutants from the perspective of sources or constituents. Few studies have examined such associations using source and constituents simultaneously, and even less are based on large-scale, nationally representative data.

Intermediate- and long-term associations between air pollution and ambient temperature and glycated hemoglobin levels in women of child bearing age.

Background: Air pollution has been linked to obesity while higher ambient temperatures typically reduce metabolic demand in a compensatory manner. Both relationships may impact glucose metabolism, thus we examined the association between intermediate- and long-term exposure to fine particulate matter (PM) and ambient temperature and glycated hemoglobin(HbA1c), a longer-term marker of glucose control.

Methods: We assessed 3-month, 6-month, and 12-month average air pollution and ambient temperature at 1-km spatial resolution via satellite remote sensing models (2013-2019), and assessed HbA1c at four, six, and eight years postpartum in women enrolled in the Programming Research in Obesity, Growth, Environment and Social Stressors (PROGRESS) cohort based in Mexico City.

Trends of overweight and obesity among preschool children from 2013 to 2018: a cross-sectional study in Rhine-Neckar County and the City of Heidelberg, Germany.

Background: Early childhood overweight and obesity is a growing public health concern worldwide. Few recent studies have addressed how time trends varied by sociodemographic characteristics at the regional level using large and high-quality data. This study determines how time trends vary in the prevalence of early childhood overweight and obesity by age, gender, and migration background at the regional level.

Trichoblastic fibroma mimicking sarcoma.

Trichoblastic fibroma (TF) is a benign trichogenic tumour that has both epithelial and mesenchymal components and exhibits partial to complete follicular induction.TF is rare and in our case it is mimicking sarcoma. We report a 35-year-old gentleman who presented with a lump over his left lower leg for the last 15 years.

Associations between Source-Specific Fine Particulate Matter and Mortality and Hospital Admissions in Beijing, China.

The health effects of PM exposure have become a major public concern in developing countries. Identifying major PM sources and quantifying the health effects at the population level are essential for controlling PM pollution and formulating targeted emissions reduction policies. In the current study, we have obtained PM mass data and used positive matrix factorization to identify the major sources of PM.

Mixed serous and mucinous retroperitoneal cystadenoma: an extremely rare case.

Mixed serous and mucinous retroperitoneal cyst adenoma is an extremely rare condition as most of the reported cases in the literature are primary retroperitoneal mucinous cystadenomas and primary retroperitoneal serous cystadenomas. They are initially asymptomatic and become symptomatic gradually depending on their size and anatomical extension and location. We report a 49-year-old woman with a history of right-side abdomen pain for a few years.

Changes in Public Perception and Behaviors under Compound Heatwave in COVID-19 Epidemic - Beijing, China, 2020.

Dramatic heatwaves frequently occurred simultaneously with the coronavirus disease 2019 (COVID-19) pandemic worldwide in 2020 and posed public health challenges. Public risk perceptions and behavioral responses to this compound risk need to be addressed. During heatwaves, the proportion of individuals who perceived COVID-19 to be more concerning than heatwaves decreased by 9.

Short-term PM and cardiovascular admissions in NY State: assessing sensitivity to exposure model choice.

Background: Air pollution health studies have been increasingly using prediction models for exposure assessment even in areas without monitoring stations. To date, most studies have assumed that a single exposure model is correct, but estimated effects may be sensitive to the choice of exposure model.

Methods: We obtained county-level daily cardiovascular (CVD) admissions from the New York (NY) Statewide Planning and Resources Cooperative System (SPARCS) and four sets of fine particulate matter (PM) spatio-temporal predictions (2002-2012).

Random forest model based fine scale spatiotemporal O trends in the Beijing-Tianjin-Hebei region in China, 2010 to 2017.

Ambient ozone (O) concentrations have shown an upward trend in China and its health hazards have also been recognized in recent years. High-resolution exposure data based on statistical models are needed. Our study aimed to build high-performance random forest (RF) models based on training data from 2013 to 2017 in the Beijing-Tianjin-Hebei (BTH) region in China at a 0.

Heat wave characteristics, mortality and effect modification by temperature zones: a time-series study in 130 counties of China.

Background: The substantial disease burden attributed to heat waves, and their increasing frequency and intensity due to climate change, highlight the importance of understanding the health consequences of heat waves. We explore the mortality risk due to heat wave characteristics, including the timing in the seasons, the day of the heat wave, the intensity and the duration, and the modifying effect of temperature zones.

Methods: Heat waves were defined as ≥ 2 days with a temperature ≥99th percentile for the county from 1 May through 30 September.

Forecasting incidence of infectious diarrhea using random forest in Jiangsu Province, China.

Background: Infectious diarrhea can lead to a considerable global disease burden. Thus, the accurate prediction of an infectious diarrhea epidemic is crucial for public health authorities. This study was aimed at developing an optimal random forest (RF) model, considering meteorological factors used to predict an incidence of infectious diarrhea in Jiangsu Province, China.

Short- and intermediate-term exposure to NO and mortality: A multi-county analysis in China.

Nitrogen dioxide (NO) is a well-established traffic emissions tracer and has been associated with multiple adverse health outcomes. Short- and long-term exposure to NO has been studied and is well-documented in existing literature, but information on intermediate-term NO effects and mortality is lacking, despite biological plausibility. We obtained daily NO and mortality data from 42 counties in China from 2013 to 2015.
