rs. These findings warrant additional investigation to determine if switching to electronic cigarettes may be an effective harm reduction strategy in smokers addicted to nicotine who are unable or unwilling to quit, The increase in proteases in electronic cigarette vapers remains concerning.

This is the first human study to report a marked increase in proteins critical for COVID-19 infection, including ACE2, TMPRSS2 and ADAM17, in immune cells from healthy tobacco cigarette smokers without lung disease compared to e-cigarette vapers and non-smokers. These findings warrant additional investigation to determine if switching to electronic cigarettes may be an effective harm reduction strategy in smokers addicted to nicotine who are unable or unwilling to quit, The increase in proteases in electronic cigarette vapers remains concerning.Bed bugs (Cimex spp.) (Hemiptera Cimicidae) are obligatory blood-sucking insects. Research on their behavioral response to host-derived olfactory cues will be helpful for designing more effective management tools. However, previous studies mainly focused on Cimex lectularius L., while the related studies on Cimex hemipterus (F.) have been rarely reported. In this study, we evaluated the behavioral responses of C. hemipterus to one of the crucial host-derived cues - carbon dioxide (CO2), at various concentrations. Pitfall traps baited with CO2 captured significantly more C. hemipterus (72%) than unbaited ones (28%). In the Y-tube test, bed bugs' exploratory activity (response rate) gradually decreased (from 70 to 27%) as the CO2 concentration increased (from 0.9 to 14.5%); and bed bugs exhibited a significant attraction to CO2 when the tested CO2 concentrations were between 0.9 and 7.3%. Cimex hemipterus were no longer attracted to CO2 after their antennae or mouthparts or both antennae and mouthparts were removed. In conclusion, C. hemipterus are attracted to CO2, and both antennae and mouthparts are important for CO2 perception.

Patient participation is increasingly recognized as a key component in the redesign of healthcare processes and is advocated as a means to improve patient safety.

To explore the usage of participatory engagement in patient-created and co-designed medical records for emergency admission to the hospital.

design prospective iterative development and feasibility testing of personal health records; setting an acute medical unit in a university-affiliated hospital; participants patients admitted to hospital for medical emergencies; interventions we used a design-led development of personal health record prototypes and feasibility testing of records completed by patients during the process of emergency admission. 'Express-check-in' records contained items of social history, screening questions for sepsis and acute kidney injury in addition to the patients' ideas, concerns and expectations; main outcome measures the outcome metrics focused on feasibility and a selection of quality domains, namely effectiveness tion and effective in frail and elderly patients with support from family and staff. The prototyped records were well received and felt to be practical by patients and staff. The staff indicated that reading the patients' documentation led to significant changes in their clinical management.

Medical record accessibility to patients during hospital care contributes to the co-management of personal healthcare and might add critical information over and above the records compiled by healthcare professionals.

Because influenza viruses in marine mammals can be zoonotic, our objective was to examine Canadian phocids for exposure to influenza A and B viruses in order to understand health risks to wild populations as well as to humans who consume or handle these animals. Blood was collected from 394 seals in eastern Canada from 1994 to 2005. Sera were screened for exposure to influenza viruses in three resident species of seals harbour, Phoca vitulina (n=66); grey, Halichoerus grypus (n=82); ringed, Phoca hispida (n=2), and two migrant species harp, Pagophilus groenlandica (n=206) and hooded, Cystophora cristata (n=38). Included were samples from captive grey (n=1) and harbour seals (n=8) at two aquaria. Sera were prescreened using indirect enzyme-linked immunosorbent assay (ELISA), and antibodies against influenza A virus were confirmed using a commercial competitive ELISA (IDEXX Europe B.V., Hoofddorp, the Netherlands). A subset of influenza A virus positive sera was used to determine common virus subtypes recognized by sera using reference strains. All positive sera in the indirect ELISA reacted with influenza A virus subtypes H3, H4, and H10 using a hemagglutination inhibition (HI) assay. Sera from harbour, grey, harp, and hooded seals had antibodies against influenza A and influenza B viruses (some cross-reactivity occurred). Overall, 33% (128/385) of wild seals were seropositive to influenza viruses, with the highest seroprevalence in harp (42%) followed by harbour (33%), grey (23%), and hooded (11%) seals. Antibodies were detected in both sexes and most age classes of wild seals. Two of eight captive harbour seals were seropositive to influenza B virus and four had cross-reactions to influenza A and B viruses. This study reports antibodies against influenza A and B viruses in four seal species from the same geographic area in eastern Canada.Esophageal and pharyngeal obstruction are commonly reported in marine mammals, but asphyxiation from blowhole and nasal cavity obstruction has been reported only rarely in two long-finned pilot whales (Globicephala melas), several harbor porpoises (Phocoena phocoena), and one common bottlenose dolphin (Tursiops truncatus). We describe two cases of blowhole obstruction and subsequent asphyxiation in bottlenose dolphins caused by eels. A whip eel (Bascanichthys scuticaris) was found obstructing the blowhole of a deceased dolphin from the Indian River Lagoon, Florida (2011) and a shrimp eel (Ophichthus gomesii) was found obstructing the blowhole of a deceased dolphin from Tampa Bay, Florida (2020). Normally, the respiratory and digestive tracts of cetaceans do not communicate. Rapamycin supplier Consuming large or oddly shaped prey can result in laryngeal displacement and subsequent interaction between the two systems. It is likely the eels entered the oral cavity while the dolphins were consuming or playing with prey, and laryngeal displacement enabled the eels to slither into and become stuck in the nasal passage, causing asphyxiation. These novel findings underscore the importance of continued investigation into causes of mortality in stranded marine mammals and can contribute to the knowledge of feeding ecology in bottlenose dolphins. As changing environmental conditions contribute to shifts in prey availability and abundance, mortality due to prey-related asphyxiation could become more common in odontocetes.The Northern Gannet (Morus bassanus) is a large marine bird whose whole North American population breeds in waters of eastern Canada. Opportunities to identify causes of morbidity and mortality in recently hatched birds of this species are therefore limited to this region of North America. During the three decades since 1990 of wildlife health surveillance at the Atlantic regional center of the Canadian Wildlife Health Cooperative, what appears to be a previously undescribed syndrome of ischemic leg necrosis affecting mainly hatch-year Northern Gannets has emerged, which may relate to some unique aspects of the life history of these birds. This syndrome, observed in 14 birds, is characterized by severe necrosis and fibrinopurulent inflammation of soft tissues of the feet extending along the whole tarsometatarsus. An infectious cause is proposed to explain the pattern of lesions observed in these birds, possibly favored by a specialized and rich vascular system in their legs and feet. An acute or subacute cardiomyopathy, thought to be secondary to the severe leg lesions, was also observed microscopically in six of these birds.Passive surveillance is an important component of wildlife health surveillance that allows for the identification of emerging pathogens as well as population-level threats. We investigated the most common causes of morbidity and mortality in rodents and lagomorphs submitted to the Canadian Wildlife Health Cooperative (CWHC) in Ontario and the Ontario Veterinary College (OVC) over a 30-yr period. A total of 836 cases representing 13 species of rodents and three species of lagomorph were submitted to the CWHC and the OVC wildlife pathology service. Infectious or inflammatory diagnoses were most common in our data set, followed by trauma and unknown diagnoses. The most frequently identified primary diagnosis was encephalitis with histological lesions consistent with neural larva migrans (NLM) including the presence of inflammation and malacia of brain tissue and, in some cases, characteristic nematode larvae. Other infectious diagnoses were squirrel fibroma virus and Toxoplasma gondii infections. Knowledge of common pathogens observed in various species of rodents and lagomorphs can aid in triage and treatment decisions at veterinary clinics and wildlife rehabilitation centers, and guide sample collection and test requisition at post-mortem examination.L-alanine is extensively used in chemical, food and medicine industries. Industrial production of L-alanine has been mainly based on the enzymatic process using petroleum-based L-aspartic acid as the substrate. L-alanine production from renewable biomass using microbial fermentation process is an alternative route. Many microorganisms can naturally produce L-alanine using aminotransferase or L-alanine dehydrogenase. However, production of L-alanine using the native strains has been limited due to their low yields and productivities. In this review, metabolic engineering of microorganisms for L-alanine production was summarized. Among them, the Escherichia coli strains developed by Dr. Lonnie Ingram's group which can produce L-alanine with anaerobic fermentation process had several advantages, especially having high L-alanine yield, and it was the first one that realized commercialization. L-alanine is also the first amino acid that could be industrially produced by anaerobic fermentation.Federally funded school meals can help alleviate food insecurity and meals are required to be modified when medically necessary (i.e., food allergies, special diets). The COVID-19 pandemic caused many schools across the USA to close, but schools quickly modified meal serving models. The purpose of this study was to understand how school nutrition professionals were ensuring food safety and providing special diets through these modified serving models. A survey was distributed to a convenience sample (n=504). At the time of the survey, most respondents (68.31%) had been involved in COVID-19 emergency feeding for 3-4 weeks. Results indicated that while most child nutrition professionals did not find food safety easier or more difficult during the initial onset of COVID-19, about 1/3 of respondents were not taking food temperatures during meal service and were not able to obtain the equipment necessary for holding hot foods. Most respondents (60.23%) also indicated that they were not accommodating children with special diets.
