Beliefs about COVID-19 testing and treatment: A national survey of Black and White adults.

Objectives: Knowledge, access, and use of testing and antiviral treatments is critical to managing and mitigating the continuing burden of the novel Corona Virus (COVID-19) in the United States. This study measured knowledge, attitude, behaviors, and self-reported barriers towards COVID-19 testing and outpatient anti-viral medications (OPA) treatments among Black and older individuals who face greater hospitalization and mortality from the disease. Study design: Cross-sectional structured survey. Methods: Respondents were randomly selected from an opt-in national panel in December 2022. Equal numbers of Black and White US adults over the age of 40 (n = 1037) completed the 42 item online survey. The main measures were key sociodemographic variables of respondents, race, age, political affiliation and COVID-19 attitudes, beliefs, testing behaviors, and knowledge and barriers to OPA access. Results: Overall, awareness and knowledge of COVID-19 outpatient treatments was low. Black respondents were more likely to test for COVID-19 than White respondents but less likely to know about OPA treatments. Insurance coverage was a significant factor in use of home tests. Knowledge of OPA treatments was low across groups. White respondents were more likely than Black respondents to be aware of OPA treatments (1.75, 95 % CI [1.31-2.33]) as were higher income respondents (1.13, 95 % CI [1.08-1.17]) and self-identified Liberals (1.79, 95 % CI [1.29-2.49]). Conclusions: Clinicians should know large numbers of patients may not be testing for COVID-19, nor are they aware of outpatient treatment options and may hold inaccurate beliefs about them. Developing culturally specific patient education materials are warranted to increase testing, utilization of vaccinations and OPAs.

Volatile capture technology in sustainable anaesthetic practice: a narrative review.

Anaesthetic practice contributes to climate change. Volatile capture technology, typically based on adsorption to a carbon- or silica-based substrate, has the potential to mitigate some of the harmful effects of using halogenated hydrocarbons. Anaesthetists have a professional responsibility to use anaesthetic agents which offer the greatest safety and clinical benefit with the lowest financial cost and environmental impacts. Inhalational anaesthetics should be used at an appropriate concentration with a minimal fresh gas flow via a circle system to minimise unnecessary waste. Once practice efficiencies have been maximised, only then should technical solutions such as volatile capture be employed. In this narrative review, we focus on the available literature relating to volatile capture technology, obtained via a targeted literature search and through contacting manufacturers and researchers. We found six studies focusing on the Blue-Zone Technologies Deltasorb®, SageTech Medical SID and Baxter/ZeoSys CONTRAfluran™ volatile capture systems. Though laboratory analyses of available systems suggest that > 95% in vitro mass transfer is possible for all three systems, the in vivo results for capture efficiency vary from 25% to 73%. Currently, there is no financial incentive for healthcare organisations to capture waste anaesthetic gases, and so the value of volatile capture technology requires quantification. System-level organisations, such as Greener NHS, are best positioned to commission such evaluations and make policy decisions to guide investment. Further research using volatile capture technology in real-world settings is necessary and we highlight some priority research questions to improve our understanding of the utility of this group of technologies.

Messaging White and Black Next of Kin in Advance to Promote Authorization for Tissue Donation.

Introduction: Organ Procurement Organizations seek authorization for tissue donation from next-of-kin of deceased patients. Best practices for achieving contact and authorization are unknown, notably, authorization rates are lower for Black compared to White patients. Research Questions: Can next-of-kin (NOK) contact and authorization rates be improved if they are texted prior to telephone contact? Is a text message containing an infographic more effective, and does an infographic culturally tailored to Black families improve contact and authorization rates in the Black population? Design: This three-armed randomized trial compared (1) telephonic contact initiation (control condition); (2) generic text messaging prior to telephonic contact; and (3) text messaging one of two versions of an infographic prior to telephonic contact: (a) a generic infographic or (b) a culturally tailored infographic (sent to Black NOK only) at one Northeastern Organ Procurement Organization. Results: Tissue Donation Professionals (N = 47) and 2399 White and 745 Black NOK were included, of which 35.6% were registered donors. Authorization rates were much higher for White than Black (40.1% v 16.3%, P < 0.0001). The generic infographic resulted in significantly lower rates of contact for White NOK compared to the control condition 83.5% v 89.5%, P = 0.002), but study arm assignments were not otherwise associated with differences in contact or authorization rates. Conclusion: Although the analysis did not find a benefit for text messaging, it is possible that training for staff making requests and refining the content of the messaging could be more effective.

Evaluating the Ability to ID (COVID-19) NOW: a Large Real-World Prospective Evaluation of the Abbott ID NOW COVID-19 Assay.

The Abbott ID NOW COVID-19 assay is a rapid point-of-care molecular test for SARS-CoV-2 detection. In theory, it has the potential to decrease turnaround times (TATs) and rapidly facilitate patient flow and triage. Reports for its performance have been mixed, likely due to variations in patient cohorts, preanalytical considerations, and study design. We prospectively evaluated the ID NOW performance against reference reverse transcriptase PCR (RT-PCR) tests, using dual swabs. Patients presented at a large multisite academic hospital with the highest volumes of COVID-19 admissions in Canada. From 1,968 valid swabs, 186 were true positive, 1,760 were true negative, 21 were false negatives, and 1 was false positive. At 10.5% positivity rate, the positive and negative predictive values were 99.5% and 98.8%, respectively. This led to a modest increase in the pretest probability in this cohort of individuals presenting <7 days of symptom onset. The mean times from collection to laboratory receipt and receipt to reporting were 31 and 23 min, respectively. This reduced TAT observed in our study may assist with triage of admitted patients and breaking the chain of transmission through immediate notification of status. We also observed how test performance changed with prevalence, and thus, how the test is used to "rule in" or "rule out" disease must be considered. Although the ID NOW is regarded as a rapid test, it is not high throughput and requires rapid transportation times (<1 h) that may not be plausible in large centers. The utility of this test should be considered with the observed TAT and interpreted in the context of limitations discussed. IMPORTANCE Rapid testing for COVID-19 has been recognized as one potentially important measure in managing the pandemic. However, these rapid tests vary grossly in their performance and their applicability. There have been many studies evaluating the performance of rapid tests for SARS-CoV-2 detection. However, they are frequently not prospective, and patients are not simultaneously swabbed to compare the reference standard RT-PCR. Previous ID NOW study findings are mixed, which may be due to various factors, including patient, epidemiological, and preanalytical considerations. It is critical to consider how the pretest and posttest probabilities and epidemiological factors may affect the performance as the community prevalence of disease fluctuates during this highly dynamic pandemic. We consider how the ID NOW may be utilized in different settings, with considerations of public health and infection control and prevention risk tolerance.

Measuring step count: why it is important not to assume measures are reliable.

BACKGROUND: The validity and reliability of pedometer software Apps versus the previously investigated spring lever and piezoelectric pedometers is unknown. PURPOSE: To evaluate the validity and reliability (in adults aged 18-65) of two pedometer software Apps, the Walk Star and the Accupedo, with spring lever (Digi-Walker CW 700) and piezoelectric (Omron HJ-720ITC and Tanita PD-724) pedometers in the measurement of step count. The criterion for comparison was researcher tallied direct observation of step count using an electronic E3-EHT hand held tally counter. METHODS: Eighteen participants walked for 5minutes on a treadmill at slow (2miles per hour) moderate (3miles per hour) and fast walking (4miles per hour) speeds and on urban streets and upon grass at a perceived "comfortable" walking speed. RESULTS: Bland and Altman plots show wide limits of agreement observed for the Yamax CW 700, Accupedo App and Walk Star App, suggesting these pedometers are unsuitable for measuring step counts in individuals due to high random error (indicating low reliability). Narrow limits of agreement were observed for the Omron HJ-720ITC and the Tanita PD-724 pedometers compared against Tally count and were considered suitable for use. CONCLUSION: The validity and reliability of pedometers cannot be assumed but must be tested and ensured before use in measuring step count.

Increased vaccine tolerability and protection via NF-κB modulation.

Improving adjuvant responses is a promising pathway to develop vaccines against some pathogens (e.g., HIV or dengue). One challenge in adjuvant development is modulating the inflammatory response, which can cause excess side effects, while maintaining immune activation and protection. No approved adjuvants yet have the capability to independently modulate inflammation and protection. Here, we demonstrate a method to limit inflammation while retaining and often increasing the protective responses. To accomplish this goal, we combined a partial selective nuclear factor kappa B (NF-kB) inhibitor with several current adjuvants. The resulting vaccines reduce systemic inflammation and boost protective responses. In an influenza challenge model, we demonstrate that this approach enhances protection. This method was tested across a broad range of adjuvants and antigens. We anticipate these studies will lead to an alternative approach to vaccine formulation design that may prove broadly applicable to a wide range of adjuvants and vaccines.

Spinal Opioid Tolerance Depends upon Platelet-Derived Growth Factor Receptor-ß Signaling, Not µ-Opioid Receptor Internalization.

Opioids are some of the most potent analgesics available. However, their effectiveness is limited by the development of analgesic tolerance. Traditionally, tolerance was thought to occur by termination of µ-opioid receptor (MOR) signaling via desensitization and internalization. Contradictory findings led to a more recent proposal that sustained MOR signaling caused analgesic tolerance. However, this view has also been called into question. We recently discovered that the platelet-derived growth factor receptor(PDGFR)-ß signaling system is both necessary and sufficient to cause opioid tolerance. We therefore propose a completely new hypothesis: that opioid tolerance is mediated by selective cellular signals and is independent of MOR internalization. To test this hypothesis, we developed an automated software-based method to perform unbiased analyses of opioid-induced MOR internalization in the rat substantia gelatinosa. We induced tolerance with either morphine, which did not cause MOR internalization, or fentanyl, which did. We also blocked tolerance by administering morphine or fentanyl with the PDGFR-ß inhibitor imatinib. We found that imatinib blocked tolerance without altering receptor internalization induced by either morphine or fentanyl. We also showed that imatinib blocked tolerance to other clinically used opioids. Our findings indicate that opioid tolerance is not dependent upon MOR internalization and support the novel hypothesis that opioid tolerance is mediated by intracellular signaling that can be selectively targeted. This suggests the exciting possibility that undesirable opioid side effects can be selectively eliminated, dramatically improving the safety and efficacy of opioids. SIGNIFICANCE STATEMENT: Classically, it was thought that analgesic tolerance to opioids was caused by desensitization and internalization of µ-opioid receptors (MORs). More recently, it was proposed that sustained, rather than reduced, MOR signaling caused tolerance. Here, we present conclusive evidence that opioid tolerance occurs independently of MOR internalization and that it is selectively mediated by platelet-derived growth factor receptor signaling. This novel hypothesis suggests that dangerous opioid side effects can be selectively targeted and blocked, improving the safety and efficacy of opioids.

Development of a functional rehabilitation intervention for post knee arthroplasty patients: COmmunity based Rehabilitation post Knee Arthroplasty (CORKA) trial.

Knee osteoarthritis is a common cause of disability in older people and knee arthroplasty surgery in the UK is increasing. The CORKA trial is a randomised controlled trial of rehabilitation targeted at patients identified as being at risk of a poor outcome after knee arthroplasty. This paper describes the development and delivery of the CORKA intervention. It was informed by current evidence, relevant guidelines, expert and patient opinion, practical considerations and a pilot study. The intervention is a multicomponent rehabilitation programme with the main component being an exercise programme delivered to participants in their own home. It includes functional task practice, strategies to improve adherence and where appropriate the provision of appropriate aids and equipment.

Physiotherapy rehabilitation for osteoporotic vertebral fracture-a randomised controlled trial and economic evaluation (PROVE trial).

The trial compared three physiotherapy approaches: manual or exercise therapy compared with a single session of physiotherapy education (SSPT) for people with osteoporotic vertebral fracture(s). At 1 year, there were no statistically significant differences between the groups meaning there is inadequate evidence to support manual or exercise therapy. INTRODUCTION: To evaluate the clinical and cost-effectiveness of different physiotherapy approaches for people with osteoporotic vertebral fracture(s) (OVF). METHODS: >Prospective, multicentre, adaptive, three-arm randomised controlled trial. Six hundred fifteen adults with back pain, osteoporosis, and at least 1 OVF participated. INTERVENTIONS: 7 individual physiotherapy sessions over 12 weeks focused on either manual therapy or home exercise compared with a single session of physiotherapy education (SSPT). The co-primary outcomes were quality of life and back muscle endurance measured by the QUALEFFO-41 and timed loaded standing (TLS) test at 12 months. RESULTS: At 12 months, there were no statistically significant differences between groups. Mean QUALEFFO-41: - 1.3 (exercise), - 0.15 (manual), and - 1.2 (SSPT), a mean difference of - 0.2 (95% CI, - 3.2 to 1.6) for exercise and 1.3 (95% CI, - 1.8 to 2.9) for manual therapy. Mean TLS: 9.8 s (exercise), 13.6 s (manual), and 4.2 s (SSPT), a mean increase of 5.8 s (95% CI, - 4.8 to 20.5) for exercise and 9.7 s (95% CI, 0.1 to 24.9) for manual therapy. Exercise provided more quality-adjusted life years than SSPT but was more expensive. At 4 months, significant changes above SSPT occurred in endurance and balance in manual therapy, and in endurance for those ≤ 70 years, in balance, mobility, and walking in exercise. CONCLUSIONS: Adherence was problematic. Benefits at 4 months did not persist and at 12 months, we found no significant differences between treatments. There is inadequate evidence a short physiotherapy intervention of either manual therapy or home exercise provides long-term benefits, but arguably short-term benefits are valuable. TRIAL REGISTRATION: ISRCTN 49117867.

Increased blood pressure visit-to-visit variability in patients with systemic lupus erythematosus: association with inflammation and comorbidity burden.

BACKGROUND: Blood pressure visit-to-visit variability is a novel risk factor for deleterious long-term cardiac and renal outcomes in the general population. We hypothesized that patients with systemic lupus erythematosus (SLE) have greater blood pressure visit-to-visit variability than control subjects and that blood pressure visit-to-visit variability is associated with a higher comorbidity burden. METHODS: We studied 899 patients with SLE and 4172 matched controls using de-identified electronic health records from an academic medical center. We compared blood pressure visit-to-visit variability measures in patients with SLE and control subjects and examined the association between blood pressure visit-to-visit variability and patients' characteristics. RESULTS: Patients with SLE had higher systolic blood pressure visit-to-visit variability 9.7% (7.8-11.8%) than the control group 9.2% (7.4-11.2%), P < 0.001 by coefficient of variation. Additional measures of systolic blood pressure visit-to-visit variability (i.e. standard deviation, average real variation, successive variation and maximum measure-to-measure change) were also significantly higher in patients with SLE than in control subjects. In patients with SLE, blood pressure visit-to-visit variability correlated significantly with age, creatinine, CRP, triglyceride concentrations and the Charlson comorbidity score (all P < 0.05). Hydroxychloroquine use was associated with reduced blood pressure visit-to-visit variability (P < 0.001), whereas the use of antihypertensives, cyclophosphamide, mycophenolate mofetil and corticosteroids was associated with increased blood pressure visit-to-visit variability (P < 0.05). CONCLUSION: Patients with SLE had higher blood pressure visit-to-visit variability than controls, and this increased blood pressure visit-to-visit variability was associated with greater Charlson comorbidity scores, several clinical characteristics and immunosuppressant medications. In particular, hydroxychloroquine prescription was associated with lower blood pressure visit-to-visit variability.

Impact of a national enhanced recovery after surgery programme on patient outcomes of primary total knee replacement: an interrupted time series analysis from "The National Joint Registry of England, Wales, Northern Ireland and the Isle of Man".

OBJECTIVE: We aimed to test whether a national Enhanced Recovery After Surgery (ERAS) Programme in total knee replacement (TKR) had an impact on patient outcomes. DESIGN: Natural-experiment (April 2008-December 2016). Interrupted time-series regression assessed impact on trends before-during-after ERAS implementation. SETTING: Primary operations from the UK National Joint Registry (NJR) were linked with Hospital Episode Statistics (HES) data which contains inpatient episodes undertaken in National Health Service (NHS) trusts in England, and Patient Reported Outcome Measures (PROMs). PARTICIPANTS: Patients undergoing primary planned TKR aged ≥18 years. INTERVENTION: ERAS implementation (April 2009-March 2011). OUTCOMES: Regression coefficients of monthly means of Length of stay (LOS), bed day costs, change in Oxford knee scores (OKS) 6-months after surgery, complications (at 6 months), and rates of revision surgeries (at 5 years). RESULTS: 486,579 primary TKRs were identified. Overall LOS and bed-day costs decreased from 5.8 days to 3.7 and from £7607 to £5276, from April 2008 to December 2016. Oxford knee score (OKS) change improved from 15.1 points in April 2008 to 17.1 points in December 2016. Complications decreased from 4.1 % in April 2008 to 1.7 % in March 2016. 5-year revision rates remained stable at 4.8 per 1000 implants years in April 2008 and December 2011. After ERAS, declining trends in LOS and bed costs slowed down; OKS improved, complications remained stable, and revisions slightly increased. CONCLUSIONS: Different secular trends in outcomes for patients having TKR have been observed over the last decade. Although patient outcomes are better than a decade ago ERAS did not improve them at national level.

Men's experiences of having osteoporosis vertebral fractures: a qualitative study using interpretative phenomenological analyses.

Men and women with vertebral fractures due to osteoporosis are treated differently by society and health care professionals. This can lead to inequalities in health care and affects how men with fractures view themselves as people. We need to raise awareness that men get these fractures as well as women. INTRODUCTION: There is a lack of research exploring the experience of osteoporosis from the male perspective. This study was undertaken to explore and describe the experiences of men with vertebral fractures due to osteoporosis, including their perceptions of diagnosis, treatment and changes in their sense of self. METHODS: The study consists of in-depth semi-structured interviews with nine male participants of the PROVE (Physiotherapy Rehabilitation for Osteoporotic Vertebral Fracture) study. Interviews were digitally audio recorded and fully transcribed. Data were coded in accordance with an interpretative phenomenological analysis approach to analyses. RESULTS: Three main themes are presented. (i) Osteoporosis is considered an old women's disease. (ii) Men are diagnosed and treated differently than women in the NHS. Health care inequalities exist. (iii) Changes in self can occur in men after vertebral fracture/s due to osteoporosis. CONCLUSIONS: Greater awareness that men get this condition is needed in both society in general and also by health care professionals who often do not expect osteoporosis to affect men. Approaches to diagnosis and treatment need to be considered and improved to ensure that they become appropriate and effective for men as well as women.

Reliability and validity of the Four Square Step Test in patients with hip osteoarthritis before and after total hip replacement.

OBJECTIVE: To determine the validity and inter- and intra-rater reliability of the Four Square Step Test (FSST) in assessing gait performance, balance and physical function for patients with hip osteoarthritis before and after total hip replacement (THR). DESIGN: Observational, repeated measures. SETTING: A specialist orthopaedic hospital. PARTICIPANTS: Fifty-eight participants with moderate to severe hip osteoarthritis scheduled to receive primary hip replacement within 4 months from recruitment. MAIN OUTCOME MEASURE: Time to complete the FSST, time and steps to complete the Figure of 8 Walk Test (F8W) and Berg Balance Scale score (BBS). RESULTS: The Bland and Altman limits of agreement for intra-rater measurements of the FSST were -3.2s to 3.5seconds before THR and -1.5 to 2.0seconds after THR. Limits of agreement for two different raters were -2.2 to 3.4seconds, all with small mean differences indicating little bias between raters or replications. Concurrent validity was assessed, and the FSST correlated highly with the F8W (r=0.7, P<0.001) and moderately with the BBS (r=0.6, P<0.001). Only one participant was rated as being at moderate risk of falls on the BBS, with the other participants scoring low; only one participant failed to complete the F8W. This is in contrast to the FSST, which 21 people failed to complete pre-operatively. CONCLUSIONS: The FSST is a valid and reliable measure of multi-directional stepping speed and balance, giving a more informative measure of gait performance than the F8W and BBS, and is feasible for use in a clinical population of patients both before and after THR.

Responsiveness and adaptability in community engaged biobanking research: experiences from a Hispanic community.

The success of biobanking research relies on the willingness of the public to provide biological and sociological information, donate tissue samples, and complete psychosocial questionnaires. Medical advances made through biobanking research have limited reach if tissues are not obtained from a diverse sample of individuals. Within, we describe the process of transitioning a small group of Hispanic community members who met regularly into a more formal Hispanic Community Advisory Board (HCAB) for the Genotype-Tissue Expression (GTEx) project. The sole purpose of the HCAB was to provide input and feedback on GTEx and, specifically, how researchers can best address the concerns of the Hispanic community related to tissue donation. This initial purpose was adapted to be responsive to the HCAB's request to include educating others in the Hispanic community who were not a part of the advisory board about genomic biobanking. While HCAB members' knowledge of biobanking was limited, a strong need for culturally tailored information about the impact of biobanking medical discoveries and their potential benefit to the Hispanic community was expressed. The HCAB's feedback guided revisions to GTEx study documents to specifically address concerns about language use, clarity, and context including the need for consent forms to address cultural concerns and fears. HCAB members also collaborated on the development of a walk-through exhibition which provided a visual, narrative-based explanation of GTEx and the process of tissue donation for research and biobanking purposes. The HCAB demonstrated the value of including community participation in scientific research projects, for both scientists and lay communities, and underscored the importance of developing community engagement approaches that are adaptable and responsive to community needs. Our experience with the HCAB serves as exemplar for a unique paradigm of community inclusiveness and education in research.

Is the timed loaded standing test a valid measure of back muscle endurance in people with vertebral osteoporosis?

Timed loaded standing (TLS) is a suggested measure of back muscle endurance for people with vertebral osteoporosis. Surface electromyography revealed back muscles work harder and fatigue during TLS. The test end-point and total time were associated with back fatigue. The findings help demonstrate the concurrent validity of the TLS test. INTRODUCTION: The TLS test is suggested as a measure of back muscle endurance for patients with vertebral osteoporosis. However, to date, no study has demonstrated that TLS does measure back extensor or erector spinae (ES) muscle endurance. We used surface electromyography (sEMG) to investigate the performance of the thoracic ES muscles during TLS. METHODS: Thirty-six people with vertebral osteoporosis with a mean age of 71.6 (range 45-86) years participated. sEMG recordings were made of the ES at T3 and T12 bilaterally during quiet standing (QS) and TLS. The relative (%) change in sEMG amplitude between conditions was compared. Fatigue was evaluated by analysing the change in median frequency (MF) of the sEMG signal during TLS, and the correlation between maximal TLS time and rate of MF decline was examined. RESULTS: Activity in the ES increased significantly during TLS at all electrode locations. During TLS, the MF declined at a mean rate of -24.2% per minute (95% C.I. -26.5 to -21.9%). The MF slope and test time were strongly correlated (r2 = 0.71), and at test end, the final MF dropped to an average 89% (95% C.I. 85 to 93%) of initial MF. Twenty-eight participants (78%) reported fatigue was the main reason for stopping, and for eight (22%), it was pain. CONCLUSIONS: This study demonstrates that TLS challenges the ES muscles in the thoracic region and results in ES fatigue. Endurance time and the point at which the TLS test ends are strongly related to ES fatigue.

A survey of dog and cat anaesthesia in a sample of veterinary practices in New Zealand.

AIMS: To survey current anaesthesia practices for dogs and cats in small and mixed animal practices in New Zealand in order to improve anaesthesia education. METHODS: A questionnaire was sent to 440 small and mixed animal practices, including questions regarding the type of practice, preanaesthetic examination, anaesthetic drugs and management, anaesthetic machines, monitoring and topics of interest for continuing professional development. RESULTS: Responses were obtained from 113/440 (26%) practices, with 78 (69%) respondents from small and 35 (31%) from mixed animal practices. A preanaesthetic physical examination was carried out by >95% of respondents and premedication was usually given to dogs (112/113; 99%) and cats (95/113; 85%). Acepromazine was the preferred sedative for dogs and cats, with morphine or buprenorphine. Propofol and alfaxalone were the preferred induction agents, and isoflurane was preferred for maintenance in both dogs and cats. A venous catheter was usually placed for anaesthesia in dogs (59/113; 52%), but less so in cats (39/113; 35%). Perioperative fluid was administered at 10 mL/kg/hour by 62/110 (56%) respondents. Intubation was usually used for anaesthesia in dogs (111/112; 99%), and cats (87/112; 78%). Almost 40% of respondents usually administered supplementary oxygen if patients were not intubated. Local analgesia was used by 69/111 (88%) respondents sometimes or always if applicable. Morphine or buprenorphine, and meloxicam were common choices for post-operative analgesia after neuter surgery in dogs and cats. A semiclosed (non-rebreathing) system was used in animals weighing <10 kg, and a Mapleson E or F non-rebreathing circuit was used by 66/109 (61%) practices. Only 15/111 (14%) practices had a ventilator in their practice. A dedicated anaesthetist was usually used by 104/113 (92%) practices, and apnoea alarms, pulse oximeters, thermometers and oesophageal stethoscopes were the main monitoring devices available in practices. Loco-regional block, pain management, and anaesthetic drugs were the main topics of interest for continuing education. CONCLUSIONS AND CLINICAL RELEVANCE: Responses by the veterinarians taking part in this survey indicated that they had a reasonably good standard of anaesthetic practice. A physical examination was carried out preanaesthesia, and premedication including analgesia was routinely administered to most patients. A dedicated anaesthetist usually monitored patients and most respondents reported they had access to basic anaesthetic monitoring equipment. Areas where changes could lead to improved anaesthetic practice were increased use of I/V catheterisation, endotracheal intubation, and supplementary oxygen, and reduced I/V fluid rates.

Authorization of tissues from deceased patients for genetic research.

Tissues from deceased donors provide important data for genomic research and Organ Procurement Organizations (OPOs) play a significant role. To understand the decisions of families who donated for transplantation and made decisions about donation to the Genotype-Tissue Expression Project (GTEx), we examined donation decisions of family decision makers (FDMs). 413 families were interviewed by telephone. The OPO staff who made the transplant and research requests completed self-administered surveys; a total of 309 matching surveys from 99 OPO staff were obtained. 76.8% of families donated to the GTEx project. Logistic regression analysis found that FDM consent to GTEx donation was associated with endorsement of policies to promote biobanking (OR = 1.35), positive attitudes about medical research (OR = 1.1), lack of concern regarding a breach of confidentiality (OR = 1.54), comfort with tissue donation (OR = 1.24), and prior authorization to solid organ donation (OR = 3.17). OPO staff characteristics associated with GTEx donation included being female (OR = 3.57), White (OR = 4.97), comfort with hospital staff role in donation (OR = 1.61), and number of topics discussed with families (OR = 57.9). Donor type, FDM attitudes, OPO staff sociodemographics, OPO comfort with the GTEx authorization process, and intensity of discussing research-specific issues were significantly associated with GTEx donation decisions.
