Retrospective epidemiological study of supracondylar fractures of the humeral bone in children from urban and rural areas of the Lublin region in eastern Poland

Introduction. Supracondylar fractures of the humeral bone are frequent injuries in children. It has been affirmed that supracondylar fractures have an excellent prognosis when proper treatment is applied. Objective. Present of the statistical relationships between fractures occurring and patient’s development period; the relation between development period and site of the fracture and statistical relationship between development period and gender of the patients. Also indicated are the place of residence of the hospitalized patients and time of admission to the Clinic after injury. Materials and method. Research was based on the data of paediatric patients treated in the Clinic for Paediatric Surgery, Traumatology and Paaediatric Orthopaedics, and Rehabilitation Clinic of the Medical University in Lublin, Poland, between 1986- 2010. An independent Chi-square Test was used for statistical analysis (c²). Results. The majority of patients were admitted to the Clinic on the day of injury. Of these patients, 71% lived in the urban area of the Lublin region where all the children received medical care in hospital directly after trauma; 29% of children came from the rural areas of the Lublin region, and 10% of them were admitted to hospital 24 or more hours after the injury. Conclusion. 71% of patients lived in the urban areas of the Lublin region and the main cause of injury was a fall from a higher level onto an outstretched upper left limb. Most supracondylar fractures of the humeral bone concerned children at school and adolescent age. Despite the fact that some of the hospitalised children lived in the rural areas of the Lublin region, the majority were admitted to the Clinic directly after trauma and received timely treatment

Pesticides in the atmosphere: a comparison of gas-particle partitioning and particle size distribution of legacy and current-use pesticides

This study presents a comparison of seasonal variation, gas-particle partitioning, and particle-phase size distribution of organochlorine pesticides (OCPs) and current-use pesticides (CUPs) in air. Two years (2012/2013) of weekly air samples were collected at a background site in the Czech Republic using a high-volume air sampler. To study the particle-phase size distribution, air samples were also collected at an urban and rural site in the area of Brno, Czech Republic, using a cascade impactor separating atmospheric particulates according to six size fractions. Major differences were found in the atmospheric distribution of OCPs and CUPs. The atmospheric concentrations of CUPs were driven by agricultural activities while secondary sources such as volatilization from surfaces governed the atmospheric concentrations of OCPs. Moreover, clear differences were observed in gas-particle partitioning; CUP partitioning was influenced by adsorption onto mineral surfaces while OCPs were mainly partitioning to aerosols through absorption. A predictive method for estimating the gas-particle partitioning has been derived and is proposed for polar and non-polar pesticides. Finally, while OCPs and the majority of CUPs were largely found on fine particles, four CUPs (carbendazim, isoproturon, prochloraz, and terbuthylazine) had higher concentrations on coarse particles ( >  3.0 µm), which may be related to the pesticide application technique. This finding is particularly important and should be further investigated given that large particles result in lower risks from inhalation (regardless the toxicity of the pesticide) and lower potential for long-range atmospheric transport

Benthic communities in the Southwest Atlantic Ocean: Conservation value of animal forests at the Burdwood Bank slope

The characterization of benthic communities at the Burdwood Bank slope(≥200 m depth) is provided, comprising data from the marine protected area(MPA) Namuncurá II (created in December 2018), as well as from some deepbathyal surrounding areas in the Southwest Atlantic Ocean. This information was acquired during two research cruises with RV Puerto Deseado (Argentina) during 2016 and 2017. Marine animal forests were detected in the study area: coral gardens, mainly composed of alcyonaceans, were detected in the south and west of Burdwood Bank(MPA Namuncurá II) and neighbouring areas, whereas pennatulacean aggregations were detected in the north-west of the plateau. The three-dimensional structures of live but also dead corals provide substrate and refuge to many associated species. Benthic communities dominated by sponges were also recorded between 200 and 300 m in depth. Six sites that meet the characteristics of vulnerable marine ecosystems (VMEs)are reported. Conservation strategies applied to scarcely known austral Argentinean waters ledto the establishment of a pioneer MPA (Namuncurá I). Following the management plan that aimed to establish the biodiversity of Namuncurá I and neighbouring areas, the area of protection has now been enlarged to include the southern slope of the bank (currently Namuncurá II), where marine animal forests were detected at depths below 200 m. The data presented here provide empirical evidence to support the conservation value of the region.Fil: Schejter, Laura. Consejo Nacional de Investigaciones Científicas y Técnicas.

Xenotransplantation of porcine progenitor cells in an epileptic California sea lion (Zalophus californianus): illustrative case.

BackgroundDomoic acid (DA) is a naturally occurring neurotoxin harmful to marine animals and humans. California sea lions exposed to DA in prey during algal blooms along the Pacific coast exhibit significant neurological symptoms, including epilepsy with hippocampal atrophy.ObservationsHere the authors describe a xenotransplantation procedure to deliver interneuron progenitor cells into the damaged hippocampus of an epileptic sea lion with suspected DA toxicosis. The sea lion has had no evidence of seizures after the procedure, and clinical measures of well-being, including weight and feeding habits, have stabilized.LessonsThese preliminary results suggest xenotransplantation has improved the quality of life for this animal and holds tremendous therapeutic promise
