Background: Climate change poses significant health risks, with children being particularly vulnerable to its adverse health effects. Children with asthma are expected to have worsening disease due to increased exposure to heat, air pollution, mold from flooding, and pollen. Understanding caregiver perspectives on these health harms is crucial for informing public health policy and education. Therefore, we aimed to explore caregiver perceptions of climate change-related health risks to children with asthma., Methods: In this cross-sectional study, a survey instrument was created and distributed to caregivers of children with asthma during their visits to pulmonology clinics located in an urban northeastern US setting and via email., Results: Among 198 completed surveys, 78% of participants reported high levels of concern about climate change, with most respondents agreeing that climate change has already impacted their child's health. Examples provided by respondents included worsening asthma control due to air pollution, wildfire events, pollen exposure, and rapid changes in weather. Respondents who self-identified as female had greater concern. Most respondents agreed that these topics should be further discussed with their child's doctor. Although, barriers to such discussions were noted by the respondents., Conclusion: Caregivers of children with asthma have high levels of concern regarding climate change and report adverse impacts on their child's asthma. Clinicians caring for children with asthma should consider discussing the respiratory health impacts of climate change with caregivers. However, barriers to these discussions need further examination., (© 2024 Wiley Periodicals LLC.)

Objectives: The reasons for and incidence of delay in screening colonoscopies during the coronavirus disease 2019 (COVID-19) pandemic are of major public health interest. The risks and reasons for delay likely vary between public and private institutions. This research sought to analyze data regarding the completion of screening colonoscopies after a positive fecal immunochemical test (FIT) before and during the COVID-19 pandemic and the reasons for a delay in obtaining these results at the Lt. Col. Luke Weathers, Jr. Veterans Affairs Medical Center. The goals were to evaluate the institutional resilience and analyze the problems associated with this major healthcare crisis., Methods: This closed cohort study included all positive FITs from our local Veterans Affairs (VA) medical center from October 2019 to January 2020 and July 2020 to May 2021. A total of 115 VA patients with a positive FIT prepandemic and 157 VA patients with a positive FIT during the pandemic were included. Completion rates within 180 days were measured, and charts were reviewed to identify the reasons for lack of completion. Both community and local VA procedures for veterans were included. Univariate and multivariable analyses were applied to calculate odds ratios (ORs). The Pearson χ 2 test was applied to calculate P values., Results: VA patients' percentage of timely completion was lower pre-COVID-19 than it was during the pandemic, and the percentage of delayed completion was higher pre-COVID-19 than it was during the pandemic. Comparing patients who completed a colonoscopy with those who did not, increasing age had an OR of 0.947 (95% CI 0.920-0.975), and White race had an OR of 0.504 (95% CI 0.291-0.873). Evaluating delays in colonoscopy completion, VA colonoscopies versus referral to the community had an OR of 4.472 (95% CI 1.602-12.483), and pre-COVID-19 completion versus during COVID-19 had an OR of 4.663 (95% CI 1.727-12.594) with multivariable logistic regression., Conclusions: There was a statistically significant increase in timely colonoscopy completion during the study period when compared with the pre-COVID-19 period. The completion rate was higher at the Lt. Col. Luke Weathers, Jr. VA Medical Center than a large population average in 2020, possibly related to community colonoscopies and an aggressive case management system. In addition, increasing age and White race were associated with decreased colonoscopy completion. Predictors of an increased delay in colonoscopy completion included a pre-COVID-19 positive FIT and colonoscopies performed within the VA rather than being referred to providers in the community. A common reason for delay in all of the groups was patients declining intervention and delay/lack of referral.

Background: Antibacterial effect studies of commercial antiseptics typically have evaluated hair and not the skin., Objectives: To evaluate the antibacterial effects of mousse products on both canine skin and hair., Animals: Fifteen short-haired and eight long-haired dogs without skin disease., Materials and Methods: Five mousses were applied once: (1) 2% chlorhexidine and 2% miconazole; (2) 0.05% phytosphingosine; (3) 2% salicylic acid and 10% ethyl lactate; (4) 3% chlorhexidine and 0.5% climbazole; and (5) 2% chlorhexidine and 1% ketoconazole. Skin swabs and hair were collected from application sites before treatment, and at 1 h and at Day (D)2, D4, D8, D10 and D14 post-treatment. Skin swabs and hair were placed on Mueller-Hinton plates inoculated with Staphylococcus pseudintermedius inoculum suspension. Inhibition zones were measured after incubation., Results: Inhibition was not noted with mousses 2 and 3. In mousse 5, inhibition zone sizes produced by swabs from long- and short-haired dogs were not significantly different (p = 0.105), and all swabs and hair produced inhibition until D14, regardless of hair length. By contrast, in mousse 1, inhibition zones produced by swabs from long-haired dogs were smaller than those from short-haired dogs (p < 0.001), and swabs from long-haired dogs produced a shorter duration of bacterial inhibition than hair., Conclusions and Clinical Relevance: The antibacterial effects of mousse 5 were not affected by hair length. Hair may be acceptable for evaluating effects on the skin in short-haired dogs. However, long hair may interfere with product distribution and duration of bacterial inhibition. Therefore, the evaluation of hair alone may overestimate clinically relevant antibacterial effects., (© 2023 ESVD and ACVD.)

Objectives: Pet pigs are a species of growing medical interest, and evidence-based practices for blood transfusions are needed. The objectives of this study were to quantify the prevalence of 3 blood group (Bg) phenotypes ("A" and "A weak " resulting from EAA AA and EAA AO , "0" from EAA 00 , or "-" from EAA 00 or S SS alleles) in pet pigs and compare results using a human blood-typing card (EldonCard), standard saline agglutination (SSA), and polymerase chain reaction (PCR) sequencing., Design: Cross-sectional study., Setting: University veterinary teaching hospital., Animals: Ninety-seven pet pigs from Louisiana., Interventions: Blood was sampled from randomly selected pet pigs of various breeds, anticoagulated with EDTA, and typed using each investigated test according to the manufacturers' directions or standard laboratory technique. Samples for PCR analysis were stored at -80°C until analysis. Phenotypes were screened via EldonCard. Association between Bg and sex was investigated using chi-square test, with significance at P < 0.05. Kappa (κ) statistic was used to measure the level of agreement between the 3 tests., Measurements and Main Results: Pot-bellied pigs represented the majority (84.5%) of this population, with 52 (53.6%) males and 45 (46.4%) females. Genotypic frequencies were 30%, 30%, and 40% for "EAA AA ," "EAA AO ," and "EAA 00 ," respectively. Based on EldonCard, 38 phenotypes were classified as "A," 5 as "A weak ," and 54 as "0" or "-." Results were identical for Bg, with the 3 tested techniques in 90% (45/50) of samples. Agreement between EldonCard and PCR was almost perfect (49/50 [98%], κ = 0.959; P < 0.001). Agreement between SSA and PCR, and EldonCard and SSA was substantial (46/50 [92%], κ = 0.803, P < 0.001 and 93/97 [95.9%], κ = 0.764, P < 0.001, respectively)., Conclusions: The most common blood type was "0" or "-" (55.7%), followed by "A" (39.2%) and "A weak " (5.1%). There was strong agreement between EldonCard and PCR testing. EldonCard allowed for rapid and reliable phenotype identification ("A," "A weak ," and "0" or "-") and represents a clinically applicable laboratory method for blood typing in pet pigs., (© Veterinary Emergency and Critical Care Society 2022.)

Plastic debris is thought to be widespread in freshwater ecosystems globally 1 . However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging 2,3 . Here we present a standardized cross-national survey that assesses the abundance and type of plastic debris (>250 μm) in freshwater ecosystems. We sample surface waters of 38 lakes and reservoirs, distributed across gradients of geographical position and limnological attributes, with the aim to identify factors associated with an increased observation of plastics. We find plastic debris in all studied lakes and reservoirs, suggesting that these ecosystems play a key role in the plastic-pollution cycle. Our results indicate that two types of lakes are particularly vulnerable to plastic contamination: lakes and reservoirs in densely populated and urbanized areas and large lakes and reservoirs with elevated deposition areas, long water-retention times and high levels of anthropogenic influence. Plastic concentrations vary widely among lakes; in the most polluted, concentrations reach or even exceed those reported in the subtropical oceanic gyres, marine areas collecting large amounts of debris 4 . Our findings highlight the importance of including lakes and reservoirs when addressing plastic pollution, in the context of pollution management and for the continued provision of lake ecosystem services., (© 2023.

Establishing and maintaining intravenous access for contrast medium during CT imaging can be difficult in birds due to their small size and thin walled vessels. Intraosseous (IO) catheters are an alternative to intravenous catheters and are often used for fluid or medication administration in birds. To determine the feasibility of IO iodinated contrast enhancement for CT in birds, 10 adult Hispaniolan Amazon parrots (Amazona ventralis) weighing 260-325 g, were enrolled in a prospective randomized blinded crossover group study to evaluate the differences in contrast route administration. The parrots underwent pre- and postcontrast CT scans using both routes of contrast administration with a wash-out period of at least 1 week between the two methods. Scans were evaluated subjectively for diagnostic quality and objectively with Hounsfield units measured over three organs: the brain, right kidney, and liver. All scans were diagnostic, and there was no statistically significant measurable difference in contrast enhancement between the two methods in any of the three organs. Subjectively, IO catheters were technically more difficult to place, but once in place, they were easier to manipulate for the imaging procedure and provided no complications upon removal. Minimal adverse side effects were noted from the IO catheters. In this small study, IO iodinated contrast administration was comparable in enhancement characteristics to intravenous administration for CT imaging in Hispaniolan Amazon parrots., (© 2022 American College of Veterinary Radiology.)

The COVID-19 pandemic has impacted every aspect of life and continues to affect individuals and organizations in ways no one anticipated. In an attempt to cope with alternative lifestyle patterns, many companies have formulated products and services to mitigate behavioral adjustments. Specifically, the healthcare industry has increased efforts to cope with the ramifications of this infectious disease. A focus on creating and distributing at-home testing has become a priority as companies attempt to expedite the approval, production and commercialization of tests. This paper addresses the dynamics of producing, distributing, and evaluating at-home medical tests.

Gallbladder mucocele (GBM) is a commonly diagnosed disease process in dogs that is associated with high morbidity and mortality if not recognized and appropriately managed. Although the exact mechanism of this disease process is not completely understood, previous studies in smaller populations of dogs have identified multiple factors that predispose to the development of GBM and affect survival. The purpose of this cross-sectional, retrospective study was to evaluate the effects of age, breed category, sex, preoperative antibiotic administration, gallbladder rupture, and a positive biliary culture in dogs that had a cholecystectomy performed for the treatment of GBM. The age (median: 11 years) and percentage of dogs that died within 14 days of cholecystectomy (16.7%) are similar to what have been reported in other studies. Gallbladder rupture and a positive biliary culture occurred in 20.4% and 12.5% of dogs, respectively. Dogs with a gallbladder rupture and positive biliary culture were 2.74 and 3.10 times more likely to die within 14 days of cholecystectomy, respectively. This contradicts a recent study that failed to find a significant association between survival and biliary culture result. Interestingly, younger age was associated with an increased occurrence of gallbladder rupture in that population. Because of the potential effect of gallbladder rupture and a biliary tract infection, abdominal imaging, biliary culture, and empirical preoperative antimicrobial therapy are recommended in dogs undergoing cholecystectomy for the treatment of GBM., (Copyright and/or publishing rights held by the Canadian Veterinary Medical Association.)

Objectives: To develop an ultrasound-guided cervical perineural injection technique for horses and to evaluate and compare the distribution of contrast agent among perineural, intra-articular and periarticular injections., Study Design: Prospective, experimental cadaveric study., Animals: A total of 14 equine cadaveric necks., Methods: Bilateral ultrasound-guided perineural injection technique for the caudal cervical spinal nerve roots (CSNRs 5-7) was developed. Paramagnetic or iodinated contrast was injected and the distribution of contrast was evaluated using magnetic resonance (MR) or computed tomography (CT) imaging, respectively. The presence of contrast in the CSNR region was determined by an observer unaware of the technique used for each injection performed. The ability of the perineural injection technique to distribute contrast agent to the CSNR region was compared with intra-articular and periarticular injection techniques., Results: Perineural injection delivered contrast agent to the CSNR region 100% of the time and was significantly different when compared with intra-articular injection (p = 0.008). There was no difference in ability to deliver contrast agent to the CSNR region between the perineural and periarticular injection techniques or between the intra-articular and periarticular injection techniques., Conclusion and Clinical Relevance: The ultrasound-guided perineural injection technique developed in this study accurately delivered contrast agent to the CSNR region in equine cadavers. This technique could potentially be used for the diagnosis and treatment of cervical pain in horses, particularly in cases where intra-articular cervical articular process joint injections have not been beneficial. Further studies are necessary to assess the effectiveness of the ultrasound-guided perineural injection technique in live horses., (Published by Elsevier Ltd.)

Objective: Alfaxalone is a popular veterinary anesthetic; however, research on this anesthetic in snakes has been limited to ball pythons, garter snakes and several Australian species. The objective was to evaluate the anesthetic effects of alfaxalone in corn snakes (Pantherophis guttatus), a popular pet snake., Study Design: Prospective, randomized crossover study., Animals: A total of eight corn snakes., Methods: In phase I, snakes were subcutaneously administered three doses of alfaxalone (5, 10 and 15 mg kg -1 ) in the cranial third of the body to determine the most effective dose. In phase II, a dose of 15 mg kg -1 was administered in the cranial and caudal thirds of the snakes to determine if injection site affected anesthesia duration. Heart rate (HR), respiratory rate (f R ), righting reflex, escape response, tail pinch, needle prick and tongue flick were monitored at baseline and 5 minute intervals until the snakes fully recovered., Results: Duration of anesthesia differed significantly, with higher doses lasting longer than lower doses: 5 mg kg -1 [23.8 ± 4.4 (15-30) minutes]; 10 mg kg -1 [40.6 ± 9.4 (25-55) minutes]; and 15 mg kg -1 [56.9 ± 8.4 (50-70) minutes], mean ± standard deviation (range). The tail pinch reflex was not completely lost in phase 1. There was a significant change in f R over time, but this was not related to dose. HR was not different by time or dose. Duration of anesthesia was not different after administration of alfaxalone (15 mg kg -1 ) in the cranial third versus the caudal third of the body; however, there was a significant decrease in HR and f R at this dose, regardless of injection site., Conclusions and Clinical Relevance: Based on these results, alfaxalone (15 mg kg -1 ) provides adequate anesthesia for brief procedures or intubation; however, additional analgesia is required for painful procedures., (Copyright © 2021 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia.

Objective: To determine mortality rates for dogs with severe anaphylaxis and identify potential prognostic factors., Animals: 67 dogs with suspected anaphylaxis graded as severe., Procedures: Dogs were classified on the basis of outcome as survivors and nonsurvivors. Medical records were reviewed, and data were extracted including signalment, examination findings, time to hospital admission from onset of clinical signs, CBC results, serum biochemical analysis results, coagulation testing results, and findings on abdominal ultrasonography. Initial treatment within the first 6 hours after hospital admission was recorded for analysis, specifically including the use of epinephrine, diphenhydramine, corticosteroids, antimicrobials, fresh-frozen plasma, and supplemental dextrose., Results: The overall mortality rate was 14.9% (10/67) for dogs with anaphylaxis graded as severe. Serum phosphorus concentration and prothrombin time (PT) were significantly higher in nonsurvivors, compared with survivors. Nonsurvivors had lower presenting body temperatures than survivors. Serum phosphorus concentration ≥ 12.0 mmol/L, hypoglycemia within 6 hours after hospital admission, high PT value, concurrently high PT and partial thromboplastin time (PTT) values > 50% above the reference range limit, and the need for supplemental dextrose were associated with death. The incidences of coagulopathy and peritoneal effusion were unexpectedly high (85.2% and 65.5% of dogs, respectively) but were not indicative of survival., Conclusions and Clinical Relevance: Despite the poor presenting clinical condition seen in dogs with severe anaphylaxis, the rate of survival with treatment was fairly high. Coagulopathy and the presence of peritoneal effusion were common findings in dogs with severe anaphylaxis. Serum phosphorus concentration ≥ 12.0 mmol/L, high PT value, concurrent increases of PT and PTT values > 50% above reference range limits, hypoglycemia within 6 hours after hospital admission, and the need for supplemental dextrose were associated with death.

Failure to address willingness and ability to undergo lung cancer treatment before lung cancer screening could cause patients unnecessary anxiety, cost and care. We employed an enhanced shared decision making (SDM) model to address willingness and ability to undergo lung cancer screening of low dose CT (LDCT) scanning. We hypothesized that enhanced SDM was feasible and did not discourage patients from undergoing lung cancer screening. We performed a prospective study of patients referred for lung cancer screening. We measured adherence to the LCS protocol, including consent to discuss lung cancer treatment if cancer is found and direct questions to patients about willingness and ability to undergo lung cancer treatment. We measured race, gender, adherence to the consent process and questions regarding willingness and ability to undergo lung cancer treatment and subsequent uptake of LDCT. All 190 patients have a documented SDM visit addressing the risks and benefits of lung cancer screening and consented to discuss lung cancer treatment if lung cancer is diagnosed. One hundred and seventy-nine (179) of 190 (94%) answered yes to being willing and able to undergo lung cancer treatment. One hundred and eighty-seven (187) patients underwent LDCT (98.4%). Discussion about willingness and ability to undergo lung cancer treatment should be an essential component of a SDM discussion prior to LDCT. This study demonstrated that an enhanced SDM experience is feasible in a clinical setting. Furthermore, patients proceeded with LDCT following the enhanced SDM process.

Previous studies have shown that asymmetries in upper limb sensorimotor function are dependent on the source of sensory and motor information, hand preference and differences in hand strength. Further, the utilization of sensory and motor information and the mode of control of force may differ between the right hand/left hemisphere and left hand/right hemisphere systems. To more clearly understand the unique contribution of hand strength and intrinsic differences to the control of grasp force, we investigated hand/hemisphere differences when the source of force information was encoded at two different force levels corresponding to a 20 and 70% maximum voluntary contraction or the right and left hand of each participant. Eleven, adult males who demonstrated a stronger right than left maximum grasp force were requested to match a right or left hand 20 or 70% maximal voluntary contraction reference force with the opposite hand. During the matching task, visual feedback corresponding to the production of the reference force was available and then removed when the contralateral hand performed the match. The matching relative force error was significantly different between hands for the 70% MVC reference force but not for the 20% MVC reference force. Directional asymmetries, quantified as the matching force constant error, showed right hand overshoots and left undershoots were force dependent and primarily due to greater undershoots when matching with the left hand the right hand reference force. Findings further suggest that the interaction between internal sources of information, such as efferent copy and proprioception, as well as hand strength differences appear to be hand/hemisphere system dependent. Investigations of force matching tasks under conditions whereby force level is varied and visual feedback of the reference force is available provides critical baseline information for building effective interventions for asymmetric (stroke-related, Parkinson's Disease) and symmetric (Amyotrophic Lateral Sclerosis) upper limb recovery of neurological conditions where the various sources of sensory - motor information have been significantly altered by the disease process.

Aims and Objectives: To determine selection and delivery of preoperative verbal information deemed important by nurses to relay to patients immediately prior to day surgery., Background: Elective day-case surgery is expanding, patient turnover is high and nurse-patient contact limited. In the brief time-frame available, nurses must select and precisely deliver information to patients, provide answers to questions and gain compliance to ensure a sustained, co-ordinated patient throughput. Concise information selection is therefore necessary especially given continued day surgery expansion., Study Design: Electronic questionnaire., Methods: A survey investigating nurses' choice of patient information prior to surgery was distributed throughout the UK via email addresses listed on the British Association of Day Surgery member's website (January 2015-April 2015)., Results: Participants were requested to undertake the survey within 2-3 weeks, with 137 participants completing the survey giving a 44% response rate. Verbal information deemed most important by nurses preoperatively was checking fasting time, information about procedure/operation, checking medication, ensuring presence of medical records/test results and concluding medical investigations checks. To a lesser extent was theatre environment information, procedure/operation start time and possible time to discharge. Significant differences were established between perceived importance of information and information delivery concerning the procedure/operation and anaesthesia details., Conclusion: Nurses working with competing demands and frequent interruptions, prioritised patient safety information. Although providing technical details during time-limited encounters, efforts were made to individualise provision. A more formal plan of verbal information provision could help ease nurses' cognitive workload and enhance patient satisfaction., Relevance to Clinical Practice: This study provides evidence that verbal information provided immediately prior to day surgery may vary with experience. Nurse educators and managers may need to provide greater guidance for such complex care settings as delivery of increasingly technical details during brief encounters is gaining increasing priority., (© 2016 John Wiley & Sons Ltd.)
