Why urban teens turn to guns: urban teens' own words on gun violence.

Missing from the discussion of youth and gun violence are qualitative data from diverse youth regarding their perspectives on gun violence in their communities and what will help prevent or reduce such violence. The purpose of this exploratory study was therefore to gain a deeper understanding of urban teens' perceptions of gun violence in the context of their daily lives and gather their ideas for reducing or preventing gun violence through meaningful discussions with urban teens.

Conditioning psychosis - A new type of epileptic psychosis? A case report on a bidirectional connection between epilepsy and psychosis.

Epilepsy and psychosis are not only closely related by clinical phenomena but presumably by causal factors, too. There is evidence that long-standing epileptic seizures can induce chronic psychosis. Whether chronic psychosis can cause epilepsy remains to be further investigated.

Season and size of urban particulate matter differentially affect cytotoxicity and human immune responses to Mycobacterium tuberculosis.

Exposure to air pollution particulate matter (PM) and tuberculosis (TB) are two of the leading global public health challenges affecting low and middle income countries. An estimated 4.26 million premature deaths are attributable to household air pollution and an additional 4.1 million to outdoor air pollution annually. Mycobacterium tuberculosis (M.tb) infects a large proportion of the world's population with the risk for TB development increasing during immunosuppressing conditions. There is strong eviden...

Emerging Temporal Lobe Dysfunction in People at Clinical High Risk for Psychosis.

Clinical high-risk (CHR) individuals have been increasingly utilized to investigate the prodromal phases of psychosis and progression to illness. Research has identified medial and lateral temporal lobe abnormalities in CHR individuals. Dysfunction in the medial temporal lobe, particularly the hippocampus, is linked to dysregulation of glutamate and dopamine a hippocampal-striatal-midbrain network that may lead to aberrant signaling of salience underpinning the . Similarly, lateral temporal dysfunction may...

Association of Air Pollution Exposure With Psychotic Experiences During Adolescence.

Urbanicity is a well-established risk factor for clinical (eg, schizophrenia) and subclinical (eg, hearing voices and paranoia) expressions of psychosis. To our knowledge, no studies have examined the association of air pollution with adolescent psychotic experiences, despite air pollution being a major environmental problem in cities.

Atmospheric nitrogen pollution in urban agglomeration and its impact on alpine lake-case study of Tianchi Lake.

The atmospheric pollution caused by human activities has been recognized as an important factor affecting the water quality of freshwater bodies. The process of the human factors' impact on high-altitude lakes in inland regions is not clear up to now. In this research, regions around Tianchi Lake were taken as a case study to explore the relation between the urban air pollution and alpine lake water quality. Multi-scale station observed data were analyzed for the urban NO pollution by means of relevance ana...

Impacts on human mortality due to reductions in PM concentrations through different traffic scenarios in Paris, France.

Air pollution is a well-known burden for population health and health systems worldwide. Reduction in air pollution is associated with improvements in mortality and rates of respiratory, cardiovascular and other diseases. Though air quality is a problem globally, efforts to lower air pollutant concentrations are usually regional or local. In industrialized countries, most urban air pollution is caused by vehicles, suggesting reductions in traffic would result in reductions of pollution. However, detailed da...

Using green infrastructure to improve urban air quality (GI4AQ).

As evidence for the devastating impacts of air pollution on human health continues to increase, improving urban air quality has become one of the most pressing tasks facing policy makers world-wide. Increasingly, and very often on the basis of conflicting and/or weak evidence, the introduction of green infrastructure (GI) is seen as a win-win solution to urban air pollution, reducing ground-level concentrations without imposing restrictions on traffic and other polluting activities. The impact of GI on air ...

Psychosis screening in schools: Considerations and implementation strategies.

Duration of untreated psychosis, or the time between onset of psychosis symptoms and accurate diagnosis and treatment, is a significant predictor of both initial treatment response and long-term outcomes. As such, efforts to improve rapid identification are key. Because early signs of psychosis commonly emerge in adolescence, schools have the potential to play an important role in the identification of psychosis-spectrum disorders.

Lichens as a spatial record of metal air pollution in the industrialized city of Huelva (SW Spain).

Huelva is a highly industrialized city in SW Spain hosting, among others, a Cu smelter, a phosphate fertilizer plant, a power plant, and oil refineries. This study aims to evaluate metal concentrations in lichens as bioindicators of atmospheric pollution in the impacted urban areas. Xanthoria parietina species from Huelva and nearby villages, as well as reference samples from remote, non-contaminated urban areas, were analyzed for trace elements (V, Cr, Mn, Co, Ni, Cu, Zn, Sr, As, Cd, Sb, Cs, Ba, La, Ce, Pr...

'Something wasn't quite right': a novel phenomenological analysis of internet discussion posts detailing initial awareness of psychosis.

A significant number of psychosis studies have focussed on and have attempted to model and frame the earliest psychosis experiences. Using a wide array of methodologies and targeting a variety of 'at risk' groups, researchers have offered much to inform our treatment responses, and understanding of psychosis onset and development.

Validity of Asthma Disease Direction, Bother and Risk as Self-reported Asthma Morbidity Measures in Urban Teens.

Prenatal brain development as a target for urban air pollution.

Air pollution is the main urban-related environmental hazard and one of the major contributors to the global burden of disease based on its cardio-vascular-respiratory impacts. In children, exposure to urban air pollution is associated, among others, with decelerated neurodevelopment early in life and increased risk of neurodevelopmental problems such as attention deficit-hyperactivity disorder, autism spectrum disorders, academic failure and the start of Alzheimer's pathogenesis. However, the evidence of t...

Microplastic Pollution in Surface Water of Urban Lakes in Changsha, China.

As emerging pollutants, microplastics have attracted the attention of scholars from all over the world. However, there is a lack of research on freshwater areas, even in densely populated urban areas. This study investigated eight urban lakes in Changsha, China. It was found that microplastic concentrations ranged from 2425 ± 247.5 items/m to 7050 ± 1060.66 items/m in the surface water of research areas and the maximum concentration was found in Yuejin Lake, a tourist spot in the center of the city. Anthr...

To assess the impact of an aerial chronic urban pollution (UP) on the severities of some facial signs of Chinese men living in two close but differently polluted Chinese cities.

Climate-Conscious Urban Growth Mitigates Urban Warming: Evidence from Shenzhen, China.

Urban growth comes with significant warming impacts and related increases in air pollution concentrations, so many cities have implemented growth management to minimize 'sprawl' and its environmental consequences. However, controlling the amount of growth is costly. Therefore, in this paper, we focus on urban warming and investigate whether climate-conscious urban growth planning (CUGP), i.e., urban growth with the same magnitude but optimized spatial arrangements, brings significant mitigation effects. Fir...

Which decreases in air pollution should be targeted to bring health and economic benefits and improve environmental justice?

Fine particulate matter (PM) exposure entails large health effects in many urban areas. Public measures aiming at decreasing air pollution are often designed without targeting an explicit health benefit. Our objective was to investigate the health and economic benefits and the social inequalities in exposure resulting from several scenarios of reduction of PM exposure, in order to support decisions about urban policies.

Association Between Duration of Untreated Psychosis and Frontostriatal Connectivity During Maintenance of Visuospatial Working Memory.

A longer duration of untreated psychosis (DUP) has been linked with poor clinical outcomes and variation in resting-state striatal connectivity with central executive regions. However, the link between DUP and task-based activation of executive neurocognition has not previously been examined. This functional magnetic resonance imaging study examined the association between DUP and both activation and frontostriatal functional connectivity during a visual working memory (WM) paradigm in patients with first-e...

Using citizen science to speed up plastic collection and mapping of urban noise: Lessons learned from Denmark.

Pollution is a widespread global problem, in which there is a particular need to involve the general populations. Approaches for involving the public in order to contribute for reaching a sustainable environment may include plastic collection and mapping of urban soundscape.

Clinical and Demographic Correlates of Stigma in First Episode Psychosis: The Impact of Duration of Untreated Psychosis.

To evaluate the relationships between perceived stigma and duration of untreated psychosis (DUP), demographic characteristics, and clinical and psychosocial functioning in persons with first episode of psychosis (FEP).

Urban birth and psychotic experiences in the United States.

There is a preponderance of evidence, much of it from Northern Europe, suggesting a link between urban residence and risk for psychotic disorders. Since the meanings and correlates of urban living differ across contexts, this association may not be universal. In a recent multisite study, the association was evident in Northern Europe, but not in other high-income European countries (e.g. Spain, Italy). Psychotic experiences (PEs) are subclinical manifestations of psychosis (typically mild and transient) tha...

Association between epigenetic age acceleration and depressive symptoms in a prospective cohort study of urban-dwelling adults.

This study tests associations of DNA methylation-based (DNAm) measures of epigenetic age acceleration (EAA) with cross-sectional and longitudinal depressive symptoms in an urban sample of middle-aged adults.

Effects of road salt on microbial communities: Halophiles as biomarkers of road salt pollution.

Increased use of salting to de-ice roadways, especially in urban areas, is leading to elevated salinity levels in soil as well as surface- and ground water. This salt pollution may cause long-term ecological changes to soil and aquatic microbial communities. In this study, we examined the impact on microbial communities in soils exposed to urban road salt runoff using both culturing and 16S amplicon sequencing. Both methods showed an increase in halophilic Bacteria and Archaea in samples from road salt-expo...
