title: Supplementary Material for: Acute Kidney Injury Following Acute Ischemic Stroke and Intracerebral Hemorrhage: A Meta-Analysis of Prevalence Rate and Mortality Risk

description: <b><i>Background:</i></b> The epidemiology of acute renal dysfunction after stroke is routinely overlooked following stroke events. Our aim in this meta-analysis is to report the prevalence of acute kidney injury (AKI) following acute stroke and its impact on mortality. <b><i>Methods:</i></b> A systematic literature search was performed on PubMed, EMBASE and Google Scholar for observational studies examining the prevalence and mortality risk of stroke patients with AKI as a complication. The pooled prevalence rates and odds ratios for mortality risk were calculated using subgroup analyses between the stroke subtypes: acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH). <b><i>Results:</i></b> A total of 12 studies (4,532,181 AIS and 615,636 ICH) were included. The pooled prevalence rate of AKI after all stroke types was 11.6% (95% CI 10.6–12.7). Subgroup analyses revealed that the pooled prevalence rate of AKI after AIS was greater but not statistically significantly different than ICH (19.0%; 95% CI 8.2–29.7 vs. 12.9%; 95% CI 10.3–15.5, <i>p</i> = 0.5). AKI was found to be a significant risk factor of mortality in AIS (adjusted OR [aOR] 2.23; 95% CI 1.28–3.89; I<sup>2</sup> = 98.8%), whereas this relationship did not reach statistical significance in ICH (aOR 1.20; 95% CI 0.68–2.12; I<sup>2</sup> = 74.2%). <b><i>Conclusions:</i></b> This meta-analysis provides evidence that AKI is a common complication following both AIS and ICH and it is associated with increased mortality following AIS but not ICH. This highlights the need for early assessment of renal function in the acute phase of AIS, in particular, and avoidance of factors than may induce AKI in vulnerable patients.

title: Computer vision for improved estimates of SO<sub>2</sub> emission rates and plume dynamics

description: Imaging cameras operating at ultraviolet (UV) and infrared (IR) wavelengths can measure sulphur dioxide (SO<sub>2</sub>) gas path concentrations or slant column densities. These measurements are useful in a variety of applications including the monitoring of emissions from volcanoes and also emissions from stacks at industrial plants and on ships. The usefulness of these data is increased if the emission rates (or fluxes) of the gases can also be estimated. Here we present an optical flow algorithm that allows rapid and accurate estimates of emission rates using both UV and IR camera imagery sampling at around 1 Hz or higher. Examples are provided from measurements made at Turrialba volcano, Costa Rica, and also at a ship in Hong Kong harbour. Other aspects of the properties of the fluid flow are also introduced, notably the divergence and the vorticity of the two-dimensional wind field. We demonstrate how the divergence can be used in a new method to calculate the emission rate and show how rotational effects observed in volcanic plumes and the resulting entrainment of ambient air affects plume rise and can be observed using vorticity. This is an important aspect for understanding the emplacement of gases and particles into the atmosphere that are subsequently transported by atmospheric winds, sometimes causing pollution episodes at long distances from the source.

title: Supplementary Material for: Pituitary Dysfunction in Pediatric Patients with Optic Nerve Hypoplasia: A Retrospective Cohort Study (1975–2014)

description: <b><i>Background/Aims:</i></b> The risk factors for pituitary hormone dysfunction (PHD) in children with optic nerve hypoplasia (ONH) are not well understood. This study identified the type, timing, and predictors of PHD in children with ONH. <b><i>Methods:</i></b> ONH patient charts were reviewed retrospectively. The incidence rate of PHD was calculated assuming a Poisson distribution. Predictors of PHD were identified through a multivariable Cox proportional hazards model. <b><i>Results:</i></b> Among 144 subjects with ONH, 49.3% (<i>n</i> = 71) developed PHD over 614.7 person-years of follow-up. The incidence was 11.55 (95% confidence interval [CI]: 9.02–14.57/100 person-years). The median time to first PHD was 2.88 (interquartile range: 0.02–18.72) months. Eighty-two percent developed their first PHD by their 5th and 90% by their 10th birthday, and 89% within 5 years of ONH diagnosis. Prematurity (adjusted hazard ratio [aHR]: 0.33; 95% CI: 0.1–1.07), blindness (aHR: 1.72; 95% CI: 1.03–2.86), maternal substance abuse (aHR: 1.51; 95% CI: 0.91–2.48), abnormal posterior pituitary (aHR: 3.8; 95% CI: 2.01–7.18), and hypoplastic/absent anterior pituitary (aHR: 2.52; 95% CI: 1.29–4.91) were significant predictors of PHD. <b><i>Conclusions:</i></b> The clinical predictors of PHD included blindness, pituitary gland abnormalities, and maternal substance abuse. These predictors help clinical decision-making related to the need for and frequency of hormone testing in pediatric patients with ONH.

title: Peatland substrates in northern KwaZulu-Natal: a study of the forming environments, properties and an approach towards classification

description: Peatlands in South Africa are rare and fulfil important ecological functions but are threatened by degradation. Because of this peatlands have gained increasing attention from scientists during the last two decades. However, knowledge of the peatland substrates and the means to classify them is limited. This study was conducted in peatlands of the Maputaland Coastal Plain. The approach uses the German Soil Mapping directive ‘KA5’, which acknowledges the accumulation process of substrates and botanical peat types. The aims were to investigate which substrates occur, whether these have affinities to certain hydrogeomorphic wetland types (HGMTs), and to determine the physical and chemical properties. Seven peatlands in five different HGMTs were investigated along 19 transects with 141 soil profiles and 674 horizons. In total 15 different peatland substrates were encountered and characterised, amongst them raphia peat, ficus peat and peat-gyttja, which have not been described previously. Mean values were determined for organic matter content, bulk density, degree of decomposition, porosity, pH and carbon/nitrogen ratio. A substrate reference scheme was also developed and classifies the encountered substrates with respect to their occurrence in HGMTs.

title: Habitat variables associated with encounters of Hottentot Buttonquail <i>Turnix hottentottus</i> during flush surveys across the Fynbos biome

description: The Hottentot Buttonquail <i>Turnix hottentotus</i> is an endangered terrestrial turnicid and is endemic to the Fynbos biome, South Africa. Due to its secretive nature and apparent rarity almost nothing is known about the species, but its range has been subject to anthropogenic modification, invasion by alien plant species and is vulnerable to climate change. To model covariates associated with the presence of Hottentot Buttonquail we undertook flush surveys across the Fynbos biome, covering 275 km. Habitat variables at encounter sites were recorded in vegetation plots, as well as locations without encounters. There was a critical number of observers needed during a flush survey in order to account for buttonquail presence, with no encounters with less than five participants. After accounting for this, we found probability of encounters decreased with increasing time-since-fire. Probability of encounters were also negatively associated with increasing percentage grass and other vegetation cover. We also found no association between percentage cover of Restionaceae plants and encounter probability, considered previously to be the best indicator of Hottentot Buttonquail presence. This information will be of use to those interested in managing habitat for this species and should inform future conservation efforts.

title: Matura NP ESA vegetation survey

description: Study of the vegetation and plant communities of Matura National Park through plot inventories. Survey sites were chosen through stratified sampling using GIS layers to account for variability caused by topography, climate, geology, altitude, slope exposure and human disturbance. <br><br>Twenty-five (254) nested 50 m x 50 m permanent sample plots were established in Matura National Park, along a roughly N-S transect line (trail) connecting the two main access routes into the park (from Grande Rivière to Salybia). This trail follows geographical ridges and is set up as a permanent trail for future monitoring. <br><br>Sample plots were positioned in sets of three plots preferably on W-facing slopes: one plot on the ridge, one in the middle slope, and one at the base of the slope. Plots are homogeneous in vegetation, excluding disturbances, and away from trails and streams. <br><br>All trees and lianas with diameter 10 cm or above at breast height were tagged, inventoried and collected. Within a central 12 x 50 m subplot all trees and lianas with diameter 2.5 – 10 cm were equally surveyed and tagged. Ground flora and epiphytes are recorded in five 2m x 2m quadrats positioned along the centre line. <br>Herbarium specimens were collected for all recorded plants, and identified at the National Herbarium of Trinidad.<br><br> The vegetation research shows that the area has important biodiversity values. Over 200 species of trees and lianas were recorded so far for Matura National Park. This includes one species never recorded before in Trinidad. Five distinct plant communities were recognized through the survey. The plant community found on the higher ridges of the northern Range, which corresponds with montane forest vegetation, has the highest plant diversity. Seven endemic trees and one endemic tree fern were found to occur in the Matura National Park ESA and therefore protected within MNP.
