ABSTRACT Long-term ecological studies were initiated shortly after an April 1985 release of 452,550 gallons of a Southern Louisiana crude oil into a 1750-acre electric power plant cooling lake. Aquatic plants (macrophytes) in the most heavily oiled region of the lake were coated with oil and most had died by late summer 1986. Macrophytes from lightly oiled areas of the lake had nearly recovered by late summer 1986. Macrophytes in other parts of the lake were completely unaffected by the release of oil. A year after the release, diversity and abundance of bottom-living animals decreased in the most heavily oiled parts of the lake and previously dominant insect larvae were replaced by opportunistic oligochaetes. Complete recovery of the most severely affected benthic communities required four years in the deep parts of the lake and five years in shallow areas. There was a small kill of fish ($$200 fish) immediately after the release and a small decrease in the abundance of preferred recreational fish species (largemouth bass and white crappie) during the summer after the release. However, between 1986 and 1991, abundance of recreational fish in the lake was comparable to that before the accident. Fish did not accumulate sufficient PAH in edible tissues to pose a health risk to human consumers.

In recent years, the frequency of mass mortality events in marine ecosystems has increased, and several populations of benthic organism have been affected, reducing their density and changing their size and age structure. Few details are known about the dynamics of these populations over long time intervals. In late summer of both 1999 and 2003 two drastic mass mortality events, co-occurring with anomalous temperature increases, affected the northwestern Mediterranean rocky coastal communities. Due to these events the Paramuricea clavata population living at the western edge of La Spezia Gulf (Italy) was stricken, and 78% of the colonies died. This population was monitored from 1998 (pre-mortality) until 2013. This paper deals with the photographic sampling of permanent plots carried out in 2013. The findings were compared with those from the previous sampling series. This long-term, non-destructive sampling highlights the demographic trajectory of the octocoral population there after two anomalous mortality events, indicating that some new drop-point between local extinction and complete recovery may be have been reached. Long-term monitoring (including pre-mortality data) could allow evaluating the effects of global climate change on the conservation of impacted populations.

This study aimed to identify educational needs and determine priorities in nursing care for home visit nurses providing services within the national long-term care insurance system in South Korea. This cross-sectional descriptive study assessed the educational needs of 92 home visit nurses. Participants’ characteristics were analyzed using percentages, averages, and standard deviations. Educational needs were calculated for participants’ current and required competency levels, utilizing the paired t-test, Borich’s educational needs formula, and the locus for focus model. Four main categories were identified as top priorities: (1) health assessment, (2) cognitive function care, (3) disease management, and (4) medication management. The study’s findings could support the development of appropriate and responsive education and training programs for home-visit nurses—as it reflects the actual needs of this group.

Acute kidney injury (AKI) is a common clinical syndrome characterized by rapid impairment of kidney function. The incidence of AKI and its severe form AKI requiring dialysis (AKI-D) has been increasing over the years. AKI etiology may be multifactorial and is substantially associated with increased morbidity and mortality. The outcome of AKI-D can vary from partial or complete recovery to transitioning to chronic kidney disease, end stage kidney disease, or even death. Predicting outcomes of patients with AKI is crucial as it may allow clinicians to guide policy regarding adequate management of this problem and offer the best long-term options to their patients in advance. In this manuscript, we will review the current evidence regarding the determinants of AKI outcomes, focusing on AKI-D.

Chloride Concentrations

The results of an extensive hydrogeological investigation of the effects of de-icing road salts on Highway 55 near Trois-Rivières-Ouest indicate that a salt lens with chloride concentrations exceeding 800 mg/L exists below the highway. Maximum chloride concentration at the nearby pumping wells, not exceeding 140 mg/L, is reached only in late summer, whereas the maximum chloride infiltration follows the spring snowmelt. About 1 year's worth of road salts is retained in the unsaturated zone. The salt lens, in the upper part of the aquifer beneath the highway, has developed to a thickness of 8 m and a width of 400 m and constitutes a linear source of salts for the aquifer. The shape of this lens is distorted by the action of the pumping wells, and the lens is partly depleted by the end of the summer. Because of the particular characteristics of the aquifer at the site studied and the exploitation methods, no long-term threat to the water quality is foreseen.

Introduction Benign paroxysmal vertigo (BPV) is characterized by recurrent attacks of dizziness in a healthy child. Complete recovery typically takes place during childhood, and an epidemiological link with migraine has been pointed out. Nevertheless, data concerning long-term patient outcome are scarce. Subjects and methods We analyzed the clinical data of 17 patients diagnosed with BPV between 1991 and 2008 in our neuropediatric department; we particularly focused on family medical history and long-term patient outcome by reviewing their medical files and by interviewing the families with a standardized questionnaire administered by phone. Results Thirteen families responded to the questionnaire, performed 1.1 to 24.5 years after onset. Among 10 patients older than 11 years of age, five continue to suffer attacks of vertigo. Median age at recovery was six years. Nine subjects exhibited migraine, including all six aged 15 years or older. There was a first-degree history of migraine in eight out of 13 children. Conclusion BPV may not be a homogeneous condition, as some children have a poorer prognosis than others. The strong link with migraine, already noticed by previous authors, led us to discuss the pathophysiology of this condition.

Environmental change is the norm and it is likely that, particularly on the geological timescale, the temperature regime experienced by marine organisms has never been stable. These temperature changes vary in timescale from daily, through seasonal variations, to long-term environmental change over tens of millions of years. Whereas physiological work can give information on how individual organisms may react phenotypically to short-term change, the way benthic communities react to long-term change can only be studied from the fossil record. The present benthic marine fauna of the Southern Ocean is rich and diverse, consisting of a mixture of taxa with differing evolutionary histories and biogeographical affinities, suggesting that at no time in the Cenozoic did continental ice sheets extend sufficiently to eradicate all shallow-water faunas around Antarctica at the same time. Nevertheless, certain features do suggest the operation of vicariant processes, and climatic cycles affecting distributional ranges and ice-sheet extension may both have enhanced speciation processes. The overall cooling of southern high-latitude seas since the mid-Eocene has been neither smooth nor steady. Intermittent periods of global warming and the influence of Milankovitch cyclicity is likely to have led to regular pulses of migration in and out of Antarctica. The resultant diversity pump may explain in part the high species richness of some marine taxa in the Southern Ocean. It is difficult to suggest how the existing fauna will react to present global warming. Although it is certain the fauna will change, as all faunas have done throughout evolutionary time, we cannot predict with confidence how it will do so.

AbstractFisheries have global socioeconomic and ecological effects. Long-term ecological studies could be beneficial to ecosystem approach management and biodiversity conservation, however, they are rare. In this study, the impacts of bottom trawling on a traditional fishing ground in the Eastern Mediterranean were addressed and an improvement in diversity metrics and ecological quality status were detected and ascribed to the Greek economic crisis. After 18 years, there was a modest increase in species richness, total abundance, and ecological status in the unaffected zone and more pronounced improvement in the trawled zone pointing at a possible link to a decrease in fishing effort. This upturn emphasized the strong link between financial activities and ecology. The present study underlines the multiple and variable effects of economy not only on countries and citizens but also on the environment and ecosystem conservation and management.

It is essential that oncological patients treated with antiresorptives or antiangiogenic drugs diagnosed Medication Related Osteonecrosis of the Jaw (MRONJ) must be treated in an interdisciplinary fashion. The patient’s stomatognathic system should be examined preventatively prior to the initiation of antiresorptive drugs in order to avoid pathological buccal manifestations, following the same healthcare clinical protocols used for patients receiving head and neck radiotherapy. Additionally, patients should be informed of the precautions to be taken, including regular dental appointments for oral health assessment. The risk of developing MRONJ should be evaluated according to the type of antiresorptives or antiangiogenic drugs administered and treatment duration. In the case of MRONJ, its fundamental characteristic is positioned in the biochemical particularity of the pharmacokinetic expression of antiresorptive drugs, reversibly (DS) or irreversibly (BPs) inhibiting the functionality of the osteoclast. Therefore, the consideration of invading bone tissue as little as possible and performing resective therapies in cases of systemic infectious spread follows, since its long-term resolution would not be effective because the drug (BPs) has frank accumulation at a distance, a characteristic used by treating doctors and it would not have clinical relevance to suggest its suspension. According to the recommendations of AAOMS; Task Force and AOCMF coincide with the sharing of consensus on minimally invasive manipulations once the necrotic foci have been installed and the preventive attitude prevails of eliminating all septic foci prophylactically before starting therapy with antiresorptive drugs. There are positions with a trend more committed to frank bone manipulation with the aim of evacuating the infectious problem and other more conservative positions in order not to expand drug necrosis volumetrically due to bone accumulation of BPs or DS.
