Cross-sectional survey of sources of information accompanying veterinary product advertisements in two professional print publications.

BACKGROUND: Veterinarians should be able to easily access scientific evidence about medical products and devices to incorporate into their clinical decision making. While the characteristics and quality of supporting information accompanying device and pharmaceutical advertisements have been studied in human medicine, little is known about this topic in veterinary medicine. The aim of this study was to characterise the supporting information provided by manufacturers of prescribed products, tests or devices in promotional material found in two commonly read UK-based veterinary publications. METHODS: Advertisements contained in issues of two veterinary periodicals published between July 2017 and July 2018 were analysed for advertisement and product characteristics and for items of accompanying information. Literature searches were conducted to assess the availability of peer-reviewed sources of information on advertised products. RESULTS: A minority (16%) of the 451 analysed advertisements were accompanied by references to peer-reviewed literature, despite the availability of scientific literature for many of the products advertised. LIMITATION: This study sampled two professional publications over a narrow time period. CONCLUSIONS: There may be insufficient evidence being provided to veterinary professionals via marketing features; this may limit the accessibility of scientific information for clinical decision making around advertised products.

Point To Area of Pain: A Clinically Useful Telehealth Physical Exam Technique for Focal Nociceptive and Neuropathic Pain.

BACKGROUND: Chronic pain is a leading cause of disease burden and disability globally. The COVID-19 pandemic catalyzed a major paradigm shift in health care delivery with the universal adoption of telemedicine. Telehealth physical examination is particularly challenging and little guidance is available on this topic. OBJECTIVES: We attempt to describe the Point To the Area of Pain (PTAP) test and establish a consensus regarding its utility for musculoskeletal examination (MSK) via telehealth. STUDY DESIGN: The authors drafted an online survey. SETTING: The survey was sent to physicians and nurse practitioners within the authors' respective departments and institutions who routinely use telemedicine to treat pain METHODS: Respondents (n = 61) were asked about their primary specialty, comfort level in evaluating patients in pain, use of the PTAP test and its perceived clinical relevance to patient management, and other relevant questions. RESULTS: Respondents were predominantly trained in Physiatry (47.5%), Anesthesiology (23%), Neurology (13.1%) and Family Medicine (11.5%); 67.2% of providers treat pain related diseases > 75% of the time; 50.8% of respondents were "somewhat comfortable" at performing a virtual MSK exam and 29.5% were "not comfortable"; 65.5% utilize the PTAP test and 88.5% agree or strongly agree that this test provides extrinsic clinically relevant information. LIMITATIONS: The relatively small number of respondents. CONCLUSION: PTAP tests should not replace the standard accepted in-person or virtual physical examination in practice, but in the absence of a hands-on exam, the PTAP test is a clear and concise test that can easily be performed in conjunction with other techniques via telehealth, and in the context of assessing pain provides useful clinical information that can help guide medical decision making.

Urethral Catheter Biofilms Reveal Plasticity in Bacterial Composition and Metabolism and Withstand Host Immune Defenses in Hypoxic Environment.

Biofilms composed of multiple microorganisms colonize the surfaces of indwelling urethral catheters that are used serially by neurogenic bladder patients and cause chronic infections. Well-adapted pathogens in this niche are Escherichia coli, Proteus, and Enterococcus spp., species that cycle through adhesion and multilayered cell growth, trigger host immune responses, are starved off nutrients, and then disperse. Viable microbial foci retained in the urinary tract recolonize catheter surfaces. The molecular adaptations of bacteria in catheter biofilms (CBs) are not well-understood, promising new insights into this pathology based on host and microbial meta-omics analyses from clinical specimens. We examined catheters from nine neurogenic bladder patients longitudinally over up to 6 months. Taxonomic analyses from 16S rRNA gene sequencing and liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomics revealed that 95% of all catheter and corresponding urinary pellet (UP) samples contained bacteria. CB biomasses were dominated by Enterobacteriaceae spp. and often accompanied by lactic acid and anaerobic bacteria. Systemic antibiotic drug treatments of patients resulted in either transient or lasting microbial community perturbations. Neutrophil effector proteins were abundant not only in UP but also CB samples, indicating their penetration of biofilm surfaces. In the context of one patient who advanced to a kidney infection, Proteus mirabilis proteomic data suggested a combination of factors associated with this disease complication: CB biomasses were high; the bacteria produced urease alkalinizing the pH and triggering urinary salt deposition on luminal catheter surfaces; P. mirabilis utilized energy-producing respiratory systems more than in CBs from other patients. The NADH:quinone oxidoreductase II (Nqr), a Na+ translocating enzyme not operating as a proton pump, and the nitrate reductase A (Nar) equipped the pathogen with electron transport chains promoting growth under hypoxic conditions. Both P. mirabilis and E. coli featured repertoires of transition metal ion acquisition systems in response to human host-mediated iron and zinc sequestration. We discovered a new drug target, the Nqr respiratory system, whose deactivation may compromise P. mirabilis growth in a basic pH milieu. Animal models would not allow such molecular-level insights into polymicrobial biofilm metabolism and interactions because the complexity cannot be replicated.

Identifying biopsychosocial factors that impact decompressive laminectomy outcomes in veterans with lumbar spinal stenosis: a prospective cohort study.

ABSTRACT: One in 3 patients with lumbar spinal stenosis undergoing decompressive laminectomy (DL) to alleviate neurogenic claudication do not experience substantial improvement. This prospective cohort study conducted in 193 Veterans aimed to identify key spinal and extraspinal factors that may contribute to a favorable DL outcome. Biopsychosocial factors evaluated pre-DL and 1 year post-DL were hip osteoarthritis, imaging-rated severity of spinal stenosis, scoliosis/kyphosis, leg length discrepancy, comorbidity, fibromyalgia, depression, anxiety, pain coping, social support, pain self-efficacy, sleep, opioid and nonopioid pain medications, smoking, and other substance use. The Brigham Spinal Stenosis (BSS) questionnaire was the main outcome. Brigham Spinal Stenosis scales (symptom severity, physical function [PF], and satisfaction [SAT]) were dichotomized as SAT < 2.42, symptom severity improvement ≥ 0.46, and PF improvement ≥ 0.42, and analyzed using logistic regression. Sixty-two percent improved in 2 of 3 BSS scales (ie, success). Baseline characteristics associated with an increased odds of success were-worse BSS PF (odds ratio [OR] 1.24 [1.08-1.42]), greater self-efficacy for PF (OR 1.30 [1.08-1.58]), lower self-efficacy for pain management (OR 0.80 [0.68-0.94]), less apparent leg length discrepancy (OR 0.71 [0.56-0.91]), greater self-reported alcohol problems (OR 1.53 [1.07-2.18]), greater treatment credibility (OR 1.31 [1.07-1.59]), and moderate or severe magnetic resonance imaging-identified central canal stenosis (OR 3.52 [1.06-11.6]) moderate, OR 5.76 [1.83-18.1] severe). Using opioids was associated with lower odds of significant functional improvement (OR 0.46 [0.23-0.93]). All P < 0.05. Key modifiable factors associated with DL success-self-efficacy, apparent leg length inequality, and opioids-require further investigation and evaluation of the impact of their treatment on DL outcomes.

Critically Appraised Topics (CATs) in Veterinary Medicine: Applying Evidence in Clinical Practice.

Critically appraised topics (CATs) are evidence syntheses that provide veterinary professionals with information to rapidly address clinical questions and support the practice of evidence-based veterinary medicine (EBVM). They also have an important role to play in both undergraduate and post-registration education of veterinary professionals, in research and knowledge gap identification, literature scoping, preparing research grants and informing policy. CATs are not without limitations, the primary one relating to the rapid approach used which may lead to selection bias or restrict information identified or retrieved. Furthermore, the narrow focus of CATs may limit applicability of the evidence findings beyond a specific clinical scenario, and infrequently updated CATs may become redundant. Despite these limitations, CATs are fundamental to EBVM in the veterinary profession. Using the example of a dog with osteoarthritis, the five steps involved in creating and applying a CAT to clinical practice are outlined, with an emphasis on clinical relevance and practicalities. Finally, potential future developments for CATs and their role in EBVM, and the education of veterinary professionals are discussed. This review is focused on critically appraised topics (CATs) as a form of evidence synthesis in veterinary medicine. It aims to be a primary guide for veterinarians, from students to clinicians, and for veterinary nurses and technicians (hereafter collectively called veterinary professionals). Additionally, this review provides further information for those with some experience of CATs who would like to better understand the historic context and process, including further detail on more advanced concepts. This more detailed information will appear in pop-out boxes with a double-lined surround to distinguish it from the information core to producing and interpreting CATs, and from the boxes with a single line surround which contain additional resources relevant to the different parts of the review.

Auricular acupuncture as an adjunct for pain management during first trimester abortion: a randomized, double-blinded, three arm trial.

OBJECTIVES: To assess pain-management using auricular acupuncture as an adjunct to ibuprofen and paracervical block during first trimester uterine aspiration, and to assess auricular acupuncture's effect on anxiety. STUDY DESIGN: This randomized, double-blinded, three-arm trial enrolled women undergoing uterine aspiration for spontaneous or induced abortion. Study participants were randomized 1:1:1 to receive auricular acupuncture, placebo, or usual care alone. Participants in all groups received ibuprofen and paracervical block (usual care). The main outcome was maximum pain reported at the end of the procedure measured using a Visual Analog Scale; we compared those receiving auricular acupuncture to those receiving usual care alone. We also compared auricular acupuncture to placebo and placebo to usual care alone. Finally, we compared the maximum anxiety scores between participants randomized to auricular acupuncture, placebo, and usual care alone. RESULTS: We randomized 153 women over 9 months, and analyzed 52 participants in the auricular acupuncture group, 49 in the placebo group, and 49 in the usual care group. The groups had similar baseline characteristics. After uterine aspiration, participants reported median maximum pain scores as follows: auricular acupuncture 39.5 (interquartile range (IQR) 11, 64.5), placebo 70.0 (IQR 40.5, 84), and usual care alone 71.0 (IQR 32, 91.5) (p<0.01). In pairwise comparisons, the median maximum pain score after auricular acupuncture was lower than placebo and usual-care groups (p<0.01 for both). Post-procedure median anxiety scores were 11.5, 31.0 and 44.0, respectively (p=.01). CONCLUSIONS: Women undergoing first trimester uterine aspiration assigned to auricular acupuncture reported substantially less pain and anxiety than women assigned to placebo or usual care. IMPLICATIONS: Auricular acupuncture may be a useful adjunct to ibuprofen and paracervical block during first trimester uterine aspiration. This approach to managing pain and anxiety could avoid the operational complexities and expenses of sedation and opioid use.

Field study assessing the performance of a patient-side blood test to determine neuter status in female cats based on detection of luteinising hormone.

OBJECTIVES: The aim of this study was to assess the performance of a patient-side blood test in determining neuter status in female cats. METHODS: Residual blood samples from female cats of unknown neuter status that were admitted to four cat adoption centres in the UK were tested for luteinising hormone (LH) using the Witness LH test (Zoetis). A positive LH test result indicated that the cat was neutered. Cats were assessed for evidence of a surgical scar suggestive of prior neutering; if none was found, an exploratory laparotomy was performed to confirm neuter status. The LH test performance was assessed (sensitivity, specificity, negative and positive predictive value). RESULTS: Two hundred and thirty-six cats had both LH test and exploratory laparotomy data. The specificity of the test in detecting neutered cats was 100% (95% confidence interval 96.2-99.9) and the sensitivity was 69% (95% confidence interval 59.3-76.8). The prevalence of neutered cats in this sample was 49%. The positive and negative predictive values were 1 and 0.77, respectively. CONCLUSIONS AND RELEVANCE: The Witness LH test correctly detected all unneutered cats and thus there were no false-positive results that incorrectly indicated a cat was neutered. This study therefore suggests that positive LH test results avoid the need to perform surgery to confirm neuter status. This has significant welfare benefits for cats as it provides a lower risk, faster and less traumatic alternative to surgery and, in the shelter setting, it will have a positive impact on the cost, speed of assessment and time to rehoming of cats.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part XI: Dementia.

OBJECTIVE : To present the 11th in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of 12 important contributions to pain and disability in older adults with CLBP. This article focuses on dementia. METHODS: A modified Delphi technique was used to develop an algorithm for an approach to treatment for older adults living with CLBP and dementia. A panel of content experts on pain and cognition in older adults developed the algorithm through an iterative process. Though developed using resources available within Veterans Health Administration (VHA) facilities, the algorithm is applicable across all health care settings. A case taken from the clinical practice of one of the contributors demonstrates application of the algorithm. RESULTS: We present an evidence-based algorithm and biopsychosocial rationale to guide providers evaluating CLBP in older adults who may have dementia. The algorithm considers both subtle and overt signs of dementia, dementia screening tools to use in practice, referrals to appropriate providers for a complete a workup for dementia, and clinical considerations for persons with dementia who report pain and/or exhibit pain behaviors. A case of an older adult with CLBP and dementia is presented that highlights how an approach that considers the impact of dementia on verbal and nonverbal pain behaviors may lead to more appropriate and successful pain management. CONCLUSIONS: Comprehensive pain evaluation for older adults in general and for those with CLBP in particular requires both a medical and a biopsychosocial approach that includes assessment of cognitive function. A positive screen for dementia may help explain why reported pain severity does not improve with usual or standard-of-care pain management interventions. Pain reporting in a person with dementia does not always necessitate pain treatment. Pain reporting in a person with dementia who also displays signs of pain-associated suffering requires concerted pain management efforts targeted to improving function while avoiding harm in these vulnerable patients.Key Words.

A Mind-Body Program for Older Adults With Chronic Low Back Pain: A Randomized Clinical Trial.

IMPORTANCE: Treatment of chronic low back pain (LBP) in older adults is limited by the adverse effects of analgesics. Effective nonpharmacologic treatment options are needed. OBJECTIVE: To determine the effectiveness of a mind-body program at increasing function and reducing pain in older adults with chronic LBP. DESIGN, SETTING, AND PARTICIPANTS: This single-blind, randomized clinical trial compared a mind-body program (n = 140) with a health education program (n = 142). Community-dwelling older adults residing within the Pittsburgh metropolitan area were recruited from February 14, 2011, to June 30, 2014, with 6-month follow-up completed by April 9, 2015. Eligible participants were 65 years or older with functional limitations owing to their chronic LBP (≥11 points on the Roland and Morris Disability Questionnaire) and chronic pain (duration ≥3 months) of moderate intensity. Data were analyzed from March 1 to July 1, 2015. INTERVENTIONS: The intervention and control groups received an 8-week group program followed by 6 monthly sessions. The intervention was modeled on the Mindfulness-Based Stress Reduction program; the control program, on the "10 Keys" to Healthy Aging. MAIN OUTCOMES AND MEASURES: Follow-up occurred at program completion and 6 months later. The score on the Roland and Morris Disability Questionnaire was the primary outcome and measured functional limitations owing to LBP. Pain (current, mean, and most severe in the past week) was measured with the Numeric Pain Rating Scale. Secondary outcomes included quality of life, pain self-efficacy, and mindfulness. Intent-to-treat analyses were conducted. RESULTS: Of 1160 persons who underwent screening, 282 participants enrolled in the trial (95 men [33.7%] and 187 women [66.3%]; mean [SD] age,74.5 [6.6] years). The baseline mean (SD) Roland and Morris Disability Questionnaire scores for the intervention and control groups were 15.6 (3.0) and 15.4 (3.0), respectively. Compared with the control group, intervention participants improved an additional -1.1 (mean, 12.1 vs 13.1) points at 8 weeks and -0.04 (mean, 12.2 vs 12.6) points at 6 months (effect sizes, -0.23 and -0.08, respectively) on the Roland and Morris Disability Questionnaire. By 6 months, the intervention participants improved on the Numeric Pain Rating Scale current and most severe pain measures an additional -1.8 points (95% CI, -3.1 to -0.05 points; effect size, -0.33) and -1.0 points (95% CI, -2.1 to 0.2 points; effect size, -0.19), respectively. The changes in Numeric Pain Rating Scale mean pain measure after the intervention were not significant (-0.1 [95% CI, -1.1 to 1.0] at 8 weeks and -1.1 [95% CI, -2.2 to -0.01] at 6 months; effect size, -0.01 and -0.22, respectively). CONCLUSIONS AND RELEVANCE: A mind-body program for chronic LBP improved short-term function and long-term current and most severe pain. The functional improvement was not sustained, suggesting that future development of the intervention could focus on durability. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01405716.

Cognitive testing in older primary care patients: A cluster-randomized trial.

INTRODUCTION: This study investigated whether neuropsychological testing in primary care (PC) offices altered physician-initiated interventions related to cognitive impairment (CI) or slowed the rate of CI progression. METHODS: This 24-month, cluster-randomized study included 11 community-based PC practices randomized to either treatment as usual (5 practices) or cognitive report (CR; 6 practices) arms. From 2005 to 2008, 533 patients aged ≥65 years and without a diagnosis of CI were recruited; 423 were retested 24 months after baseline. RESULTS: CR physicians were significantly more likely to order cognitive-related interventions (P = .02), document discussions about cognition (P = .003), and order blood tests to rule out reversible CI (P = .002). At follow-up, significantly more CR patients had a medication for cognition listed in their chart (P = .02). There was no difference in the rate of cognitive decline between the groups. DISCUSSION: Providing cognitive information to physicians resulted in higher rates of physician-initiated interventions for patients with CI.

Genetic Risk Score Predicts Late-Life Cognitive Impairment.

Introduction. A family history of Alzheimer's disease is a significant risk factor for its onset, but the genetic risk associated with possessing multiple risk alleles is still poorly understood. Methods. In a sample of 95 older adults (Mean age = 75.1, 64.2% female), we constructed a genetic risk score based on the accumulation of risk alleles in BDNF, COMT, and APOE. A neuropsychological evaluation and consensus determined cognitive status (44 nonimpaired, 51 impaired). Logistic regression was performed to determine whether the genetic risk score predicted cognitive impairment above and beyond that associated with each gene. Results. An increased genetic risk score was associated with a nearly 4-fold increased risk of cognitive impairment (OR = 3.824, P = .013) when including the individual gene polymorphisms as covariates in the model. Discussion. A risk score combining multiple genetic influences may be more useful in predicting late-life cognitive impairment than individual polymorphisms.
