Managing acute disturbance in the context of COVID-19

Chronic environmental change threatens biodiversity, but acute disturbance events present more rapid and immediate threats. In 2010, a cold snap across south Florida had wide-ranging impacts, including negative effects on recreational fisheries, agriculture, and ecological communities. Here, we use acoustic telemetry and historical longline monitoring to assess the long-term implications of this event on juvenile bull sharks Carcharhinus leucas in the Florida Everglades. Despite the loss of virtually all individuals (ca. 90%) within the Shark River Estuary during the cold snap, the catch per unit effort (CPUE) of age 0 sharks on longlines recovered through recruitment within 6-8 mo of the event. Acoustic telemetry revealed that habitat use patterns of age 0-2 sharks reached an equilibrium in 4-6 yr. In contrast, the CPUE and habitat use of age 3 sharks required 5-7 yr to resemble pre-cold snap patterns. Environmental conditions and predation risk returned to previous levels within 1 yr of the cold snap, but abundances of some prey species remained depressed for several years. Reduced prey availability may have altered the profitability of some microhabitats after the cold snap, leading to more rapid ontogenetic shifts to marine waters among sharks for several years. Accelerated ontogenetic shifts coupled with inter-individual behavioral variability of bull sharks likely led to a slower recovery rate than predicted based on overall shark CPUE. While intrinsic variation driven by stochasticity in dynamic ecosystems may increase the resistance of species to chronic and acute disturbance, it may also increase recovery time in filling the diversity of niches occupied prior to disturbance if resistive capacity is exceeded.

Acute Disturbance

IntroductionSeizures are common in hospitals, both as presentations to Emergency Departments (ED) and as hospital onset seizures (HOS), occurring in ward patients hospitalised for non-seizure reasons. Prompt identification of seizure aetiology is important, as it affects prognosis and management choices. Acute symptomatic seizures due to acute disturbance of brain function have a far lower risk of recurrence compared to unprovoked seizures. Timely investigations and specialist review assesses individual risk for seizure recurrence, which then guides therapeutic decisions including antiepileptic drug (AED) use. This study includes a larger proportion of older patients than usually reported, and as such, provides important insights into seizure aetiology and management strategies in this demographic.MethodsThis retrospective survey of medical charts reviewed patients aged 18 or over with a hospital separation coded as ICD-10 G40 (Epilepsy), G41 (Status epilepticus), or R56.9 (convulsions not otherwise specified), presenting between 1 January 2008 through 30 November 2016, to a large metropolitan private hospital. 97 episodes of ED attendance for first seizure and 54 episodes of HOS were identified.ResultsMedian age was 70 years in ED-cohort and 80.5 years in HOS-cohort. Symptomatic seizure risk factors were identified in 62.89% of ED-cohort and 83.33% of HOS-cohort, including exposure to known epileptogenic drugs in 38.89% of HOS-cohort. Antiepileptic drugs (AEDs) were prescribed on discharge to 74.23% of ED-cohort and 81.48% of HOS-cohort, but far fewer had scheduled Neurologist review (58.76% of ED- and 35.19% of HOS-cohorts).ConclusionThis study includes a larger proportion of older patients than usually reported, and as such, provides important insights into seizure aetiology and management strategies in this demographic. This includes caution when prescribing known epileptogenic drugs; mindful prescription of AED on discharge; and ensuring adequate Neurologist follow-up to monitor further seizure activity, addressing seizure risk factors, and ongoing need for AED.

Diabetes mellitus type 2 is not only a chronic disease, but also refers to a group of constantly progressing pathologies. Regardless of the level of development of medicine and used therapeutic approaches, mortality from cardio-vascular complications of diabetes exceeds the figures of the General population. According to the results of Veterans Affairs Diabetes Trial it was revealed that severe hypoglycemia are predictors for the development of myocardial infarction and acute disturbance of cerebral blood circulation. Pledge of successful treatment of patients with type 2 diabetes is the adequate choice of target values of glycemia and maintaining it by means of a combination of curative (observance of dietary recommendations, reception of hypoglycemic drugs, etc.) and not drug-induced (by which primarily active self-monitoring of blood glucose) activities.

120 patients with motor disorders (pareses and paralyses) caused by acute disturbance of brain circulation were examined. Clinical examination, computered analysis of motor potential, spectrum of cardiac rhythm variability before and after treatment, psychologic testing were carried out. After 15 sessions of therapeutic loading suit usage in 71,9% of patients a stable clinical effect (P0,05) was achieved. Patients began to walk without assistance, they were able to serve themselves, their speech improved. It is stated that the results of patients rehabilitation using the chosen method are influenced not only by initial clinical features of pyramidal defect, but also by laterality of injury and safety of the most homeostatically significant baroreflex vasomotor mechanisms and cerebral mechanisms of motion preparation in combination with minimal evidence of emotional and affective disorders.
