Psychiatric institutions, their architecture, and the politics of regional autonomy in the Austro-Hungarian monarchy

This paper examines the planning process and architecture of two public psychiatric institutions built around 1900 in Trieste and Lower Austria. From 1864, the building of new asylums was the responsibility of Crown land governments, which by the end of the nineteenth century had emerged as sites of power and self-presentation by minority groups and new political parties. At the same time, the area of asylum planning was establishing itself as a branch of asylum psychiatry and promoting the idea of the asylum as model settlement, contributing to social reform. I analyse the interaction of psychiatrists, architects and government officials involved in planning the two institutions in the context of Crown land governments' self-positioning within the empire and internationally (especially in relation to Italy and Germany). The Trieste asylum planners were working for a government controlled by Italian nationalists, but their desire for a 'modern' asylum turned them towards German models. The Christian Social government in Lower Austria sought to supplant Germany as the leader in this branch of science. The spatial arrangement and visual articulation of the two asylums is interpreted in the context of the interaction of psychiatry and the politics of regional autonomy.

The Applicability of Habitat Evaluation Methodologies in Ecological Risk Assessment

Traditionally, ecological risk assessments (ERAs) have emphasized risks to individual organisms or populations of species. Although habitats may be a potential target for chemical stressors, and are considered in the framework for ERAs, the actual use of habitat evaluation methods in this process is limited. Habitats obviously represent an important entity to protect since damaged aquatic and wildlife habitats may be totally irretrievable over a human life span compared to deleterious biochemical and physiological changes which may be reversible within the life cycle of an organism, if exposure is terminated. Habitat methods have been largely used as management tools to evaluate impacts of planned water and land development projects. Habitat evaluation methods represent a structured, systematic and logical approach to determine changes to habitats because they consider important life requisites and environmental variables limiting to species. Their use in the ERA process will provide a means to differentiate habitat changes resulting from physical, chemical and/or biological factors or a combination of such factors. In addition, minimal and optimum habitat suitability can be determined for different habitat variables under different chemical exposure scenarios. The objectives of this paper are to review several available habitat evaluation methods and discuss their use in risk assessment. Particular emphasis is given to USFWS's Habitat Evaluation Procedures (HEPs) and the Instream Flow Incremental Method (IFIM).     

Clinical characteristics,risk factors,and rate of severity of a nationwide COVID-19 Saudi cohort

ObjectiveTo evaluate COVID19 patients’ clinical characteristics, risk factors, and COVID-19 severity at baseline and over one month following hospitalization.Design, setting, and participantsThis prospective cohort study of 598 Saudi COVID19 patients recruited from 4 major medical institutions nationwide between June 01, 2020, and February 28, 2021. Patients were stratified into different demographic characteristics and COVID-19 severity scale.ResultsOf the 598 hospitalized adult COVID19 patients (mean [range] age, 57 [46 to 65] years; 59% male), 300 (50.16%) had severe clinical COVID-19. Comorbidity was high among hospitalized patients (73.5 %), with diabetes mellitus (n=; 46%) and hypertension (n=; 41%) being the most common prevalent. In a multivariate logistic regression model, patient demographics and clinical factors such as age (odds ratio [OR], 1.014 per year; 95% CI, 1.003–1.025), male sex (OR, 1.63; 95% CI, 1.02–2.62), diabetes mellitus (OR, 1.63; 95% CI, 1.06–2.49), obesity (OR, 1.93; 95% CI, 1.26–2.94), oxygen saturation<92% (OR, 4.83; 95% CI, 2.96–7.86), and high neutrophil to lymphocyte ratio (OR, 3.74 per unit; 95% CI, 1.96–7.14) were independently associated with higher COVID-19 severity. Moreover, more than 60% of male patients and middle-aged patients (40–60 years) were associated with the use of COVID-19 medications, including favipiravir and dexamethasone, during their hospital stay. Additionally, the rate of invasive mechanical ventilation was the highest in female patients (61.5%) and in middle-aged patients (46.2%). However, the death rate was slightly higher in males (56%) than in female patients and in elderly patients (52%). In Cox proportional analysis, age associated with increased risk of 60-days mortality (Hazard ratio; HR, 1.05 per year; 95% CI, 1.018–1.098). Additionally, the Riyadh region associated with more COVID-19 cases required invasive respiratory support (57.7%) and Jeddah was associated with more deceased COVID-19 cases (44%).ConclusionsThe data shows that comorbidity is associated with hospitalization among COVID-19 patients, which indicates the level of severity. Infection during the winter season (November), male gender, elderly, and those with pre-existing diabetes mellitus or obesity were associated with higher COVID-19 clinical severity.     

Assessment of the role of general,biochemical and family history characteristics in kidney stone formation

Aim

The main objective of the study was to determine the urinary risk factors involved in kidney stone formation.

Method

In this study a total number of 101 patients (64 males and 37 females) between the age group 2 and 70 years were selected. Personal characteristics like age, family history, clinical sign and symptoms, education, monthly income, living style, smoking or tobacco chewing habit, dietary intake and daily amount of drinking water were recorded.

Results

The study showed that the risk of kidney stone formation was high in the median age group (16–25 years) both in male and female population. The most important factors associated with this were lack of drinking clean water, over weight and obesity as well as family history (37.5% and 27.02% in men and women, respectively).

Conclusion

Our study has confirmed that lack of drinking sufficient amount of water, increasing weight and obesity and family history are some major factors contributing to the increased risk of kidney stone formation. Therefore it is very important to live a healthy life, drink clean water and control weight to prevent such diseases.     

Risk factors affecting the probability of damage by sika deer in plantation forests in Yamanashi Prefecture, Japan

Using a generalized linear mixed model approach, we determined the most important risk factors affecting the probability of damage by sika deer in a forest plantation in Japan. Candidate risk factors included tree species, stand age, peripheral dwarf bamboo community, topographical factors, snow depth, and human disturbance factors. Based on this model, we developed a risk map of forest damage. The model indicated that the most important risk factor was stand age, followed by tree species and maximum snow depth. Our predictive model has practical use due to its high classification accuracy (83.9%). To decrease damage from sika deer, an afforestation plan that incorporates these factors should be implemented. Because it is based on common, forest GIS data that have recently been compiled by several local governments in Japan, our modeling method of deer damage can easily be adapted to other areas.     

Environmental and Human Health Risk Assessment of Benzo(a)pyrene Levels in Agricultural Soils from the National Capital Region,Delhi, India

ABSTRACT

Exposure to benzo(a)pyrene (B(a)P) for health risk was studied in soils from the Delhi region, India. The mean and median concentrations of benzo(a)pyrene were 0.031 and 0.029 (±0.002) mg/kg, respectively. The lifetime average daily dose (LADD) for adults and children was 1.7 × 10^?8 mg kg^?1 d^?1 and 7.5 × 10^?8 mg kg^?1 d^?1, respectively, with incremental life time cancer risk (ILCR) of 1.2 × 10^?7 and 5.5 × 10^?7, respectively. The Index of Additive Cancer Risk (IACR) was 0.084. Our screening-level risk assessment shows that the observed ILCR and IACR values are much lower than the guideline values of 10^?6 ? 10^?4 (ILCR) and <1 (IACR), respectively, and therefore the measured B(a)P levels in soil may not portend environmental and human health risks.     

Incorporating Natural Variability into the Assessment of Ecological Health in Australian Dryland Rivers

Dryland rivers occur over much of Australia’s inland and have some of the most variable patterns of flow in the world. Despite their dominance in terms of Australia’s river types, dryland rivers have not been the focus of the recent increase in research on indicators of river health, mostly owing to their spatial remoteness and relatively low levels of water resource development and human disturbance. Most rivers in arid and semi-arid regions are ephemeral, and only carry significant flows during the wetter months or following infrequent but intense rainfall events. It is not known which, if any, of the existing approaches to river health assessment can be used to accurately assess the health of these large ephemeral rivers. This paper considers why the standard methods for interpreting the currently-used indicators for river health may need to be adapted for variable systems and suggests the use of trends that recognise natural variation in indicator values for undertaking this.     

Gene Flow,Risk Assessment and the Environmental Release of Transgenic Plants

The release of genetically modified plants is governed by regulations that aim to provide an assessment of potential impact on the environment. One of the most important components of this risk assessment is an evaluation of the probability of gene flow. In this review, we provide an overview of the current literature on gene flow from transgenic plants, providing a framework of issues for those considering the release of a transgenic plant into the environment. For some plants gene flow from transgenic crops is well documented, and this information is discussed in detail in this review. Mechanisms of gene flow vary from plant species to plant species and range from the possibility of asexual propagation, short- or long-distance pollen dispersal mediated by insects or wind and seed dispersal. Volunteer populations of transgenic plants may occur where seed is inadvertently spread during harvest or commercial distribution. If there are wild populations related to the transgenic crop then hybridization and eventually introgression in the wild may occur, as it has for herbicide resistant transgenic oilseed rape (Brassica napus). Tools to measure the amount of gene flow, experimental data measuring the distance of pollen dispersal, and experiments measuring hybridization and seed survivability are discussed in this review. The various methods that have been proposed to prevent gene flow from genetically modified plants are also described. The current “transgenic traits” in the major crops confer resistance to herbicides and certain insects. Such traits could confer a selective advantage (an increase in fitness) in wild plant populations in some circumstances, were gene flow to occur. However, there is ample evidence that gene flow from crops to related wild species occurred before the development of transgenic crops and this should be taken into account in the risk assessment process.     

Uncertainties in the Environmental Risk Assessment of Metals

As life has evolved in the presence of metals, the assessment of the potential adverse effects of metals on ecosystems requires a different approach than those presently used for man-made organic substances. This article provides a brief review of applications and limitations of current techniques and presents, based on recent research results, suggestions for improving the scientific relevance and accuracy of environmental risk assessments of metals. The importance of the following factors responsible for major uncertainties in current environmental risk assessments of metals are discussed: factors affecting metal bioavailability and toxicity, the potential importance of deficiency effects (for essential metals), and field extrapolation of laboratory toxicity data. Possible (regulatory) consequences of inaccurately assessing the natural background concentrations of metals and acclimatization/adaptation potential of laboratory organisms and resident communities are illustrated using examples of recent research, hypothesis development, and a probabilistic environmental risk assessment.     

Assessment of genetic diversity in the critically endangered Australian corroboree frogs, Pseudophryne corroboree and Pseudophryne pengilleyi, identifies four evolutionarily significant units for conservation

The iconic and brightly coloured Australian northern corroboree frog, Pseudophryne pengilleyi , and the southern corroboree frog, Pseudophryne corroboree are critically endangered and may be extinct in the wild within 3 years. We have assembled samples that cover the current range of both species and applied hypervariable microsatellite markers and mitochondrial DNA sequences to assess the levels and patterns of genetic variation. The four loci used in the study were highly variable, the total number of alleles observed ranged from 13 to 30 and the average number of alleles per locus was 19. Expected heterozygosity of the four microsatellite loci across all populations was high and varied between 0.830 and 0.935. Bayesian clustering analyses in structure strongly supported four genetically distinct populations, which correspond exactly to the four main allopatric geographical regions in which the frogs are currently found. Individual analyses performed on the separate regions showed that breeding sites within these four regions could not be separated into distinct populations. Twelve mtND2 haplotypes were identified from 66 individuals from throughout the four geographical regions. A statistical parsimony network of mtDNA haplotypes shows two distinct groups, which correspond to the two species of corroboree frog, but with most of the haplotype diversity distributed in P. pengilleyi . These results demonstrate an unexpectedly high level of genetic diversity in both species. Our data have important implications for how the genetic diversity is managed in the future. The four evolutionarily significant units must be protected and maintained in captive breeding programmes for as long as it is possible to do.

Ecological Risk Assessment of China's Freshwater Ecosystems Applying the Relative Risk Model: Toward an Ecosystem-Based Water Management in China

The relative risk model (RRM) was applied to evaluate the ecological risk characterization of the freshwater ecosystems in China, from both overall and region-specific levels. Ten large-scale river basins (further broken into 15 risk regions) in China were chosen as the study objects; 10 sources, two habitats, and seven endpoints were identified as risk components. The results reveal the status of ecosystem conditions, key ecological risk issues, and the spatial heterogeneity of the freshwater ecosystems in China. The policy implications for the ecosystem-based water management contained in the results are discussed. The results obtained in this article provide a deeper understanding of the ecological risk characterization of the freshwater ecosystems in China, and aid in promoting the applications of the RRM as the tool for ecosystem-based water management.     

Effects of a Transient Cancer Scare on Property Values: Implications for Risk Valuation and the Value of Life

A transient cancer scare is presented as a rare opportunity to observe the effect of a perceived increase in risk on the price of residential property. The temporary nature of the perceived excess risk allows for the isolation of a risk premium from the change in housing prices, because prices decline during this natural experiment and return to normal when the cancer scare is proven to be unfounded. Value of life measures imputed from this risk premium are orders of magnitude lower than similar values obtained by studies involving other risk-dollar tradeoffs. The likelihood of death which is taken to be valued by the risk premium is much greater in this case than in other value-of-life studies, giving support to the notion that the aversion to risk is not directly proportional to the probability of harm.     

Drift and upstream movement in Yuccabine Creek,an Australian tropical stream

Drift and upstream movement were monitored over 14 months in a seasonal upland tropical stream in northeastern Australia. There were distinct seasonal pulses in the drift with variable peak levels in the summer wet season and low more stable levels during the dry season. Drift density ranged from 0.36 to 3.98 animals per m³ (monthly mean = 1.26). There was no correlation between drift density and either benthic density or stream discharge. In the absence of catastrophic drift, drift was dispersive, not depletive in the wet season. A total of 121 taxa were caught in the 14 drift samples. Most taxa had nocturnal maximum drift levels with a peak immediately after sunset, a pattern apparently related to level of light and not temperature. Compensation for drift by upstream-moving nymphs and larvae was least during the wet season and increased during the dry season to a peak of 27% by numbers. Mean compensation was 8.2%. It is suggested that apart from in the wet season when an animal may drift substantial distances, most riffle animals will spend their larval lives in one small stretch of stream.     

Assessing the Risk of Soil Pollution around an Industrialized Mining Region Using a Geostatistical Approach

Knowledge of mobility of some heavy metals in coal mining areas is fundamental in order to understand their toxicity and geochemical behavior. This paper aims to map pollution and assess the risk to agricultural soils in a wider lignite opencast mining and industrial area. Geochemical data related to environmental studies show that the waste characteristics favor solubilization and mobilization of inorganic contaminants. The geochemical distribution of soil pollution is studied by the application of the Bayesian Maximum Entropy (BME) procedure, a versatile extension of geostatistics which allows merging spatial and temporal estimations in a single model. Results reveal a correlation range of contaminants concentrations up to 5000 m and indicate a potential forecasting range of up to five years. Inspection of the produced spatiotemporal maps indicates that the whole study area is contaminated by As and various heavy metals, a situation which seems to be more or less stable over time.     

Risk assessment and the importance of ochratoxins

The multi-faceted and potent toxicity of ochratoxin A to experimental animals, its accepted role as disease determinant in mycotoxic porcine nephropathy, its putative role in the idiopathic human disease Balkan endemic nephropathy and associated urinary tract tumours, and its widespread occurrence usually in trace amounts in foodstuffs is focussing attention on minimising human intake. Conservative risk assessment based on porcine renal disease data has set tolerable intake values rather similar to actual average human intake. However, translating experimental rat tumour data to possible human risk is proving difficult partly because, in the author's view, the finding of a low incidence of DNA adducts could arise from an artificial surge in serum concentration following rapid uptake from aqueous intragastric administration, and this probably exaggerates what would occur during more natural slow uptake from food. The need for experimental data that can assist meaningful evaluation of risk of natural intake of ochratoxin A is emphasised, but prospective legislation should be balanced against socio-economic consequences of setting over-strict limits on contamination of relevant agricultural commodities, particularly in vulnerable specialist sectors such as coffee.     

Quantifying Cancer Absolute Risk and Cancer Mortality in the Presence of Competing Events after a Myotonic Dystrophy Diagnosis

Recent studies show that patients with myotonic dystrophy (DM) have an increased risk of specific malignancies, but estimates of absolute cancer risk accounting for competing events are lacking. Using the Swedish Patient Registry, we identified 1,081 patients with an inpatient and/or outpatient diagnosis of DM between 1987 and 2007. Date and cause of death and date of cancer diagnosis were extracted from the Swedish Cause of Death and Cancer Registries. We calculated non-parametric estimates of absolute cancer risk and cancer mortality accounting for the high non-cancer competing mortality associated with DM. Absolute cancer risk after DM diagnosis was 1.6% (95% CI=0.4-4%), 5% (95% CI=3-9%) and 9% (95% CI=6-13%) at ages 40, 50 and 60 years, respectively. Females had a higher absolute risk of all cancers combined than males: 9% (95% CI=4-14), and 13% (95% CI=9-20) vs. 2% (95%CI= 0.7-6) and 4% (95%CI=2-8) by ages 50 and 60 years, respectively) and developed cancer at younger ages (median age =51 years, range=22-74 vs. 57, range=43-84, respectively, p=0.02). Cancer deaths accounted for 10% of all deaths, with an absolute cancer mortality risk of 2% (95%CI=1-4.5%), 4% (95%CI=2-6%), and 6% (95%CI=4-9%) by ages 50, 60, and 70 years, respectively. No gender difference in cancer-specific mortality was observed (p=0.6). In conclusion, cancer significantly contributes to morbidity and mortality in DM patients, even after accounting for high competing DM mortality from non-neoplastic causes. It is important to apply population-appropriate, validated cancer screening strategies in DM patients.     

Ten Years of the Relative Risk Model and Regional Scale Ecological Risk Assessment

It has been 10 years since the publication of the relative risk model (RRM) for regional scale ecological risk assessment. The approach has since been used successfully for a variety of freshwater, marine, and terrestrial environments in North America, South America, and Australia. During this period the types of stressors have been expanded to include more than contaminants. Invasive species, habitat loss, stream alteration and blockage, temperature, change in land use, and climate have been incorporated into the assessments. Major developments in the RRM have included the extensive use of geographical information systems, uncertainty analysis using Monte Carlo techniques, and its application to retrospective assessments to determine causation. The future uses of the RRM include assessments for forestry and conservation management, an increasing use in invasive species evaluation, and in sustainability. Developments in risk communication, the use of Bayesian approaches, and in uncertainty analyses are on the horizon.
