Abstract
OBJECTIVE The purpose of this study was to evaluate a sit to stand test with the walk test for the identification of unilateral cranial cruciate ligament rupture in dogs. MATERIALS AND METHODS Peak vertical force and vertical impulse were measured on a pressure-sensitive walkway, during a sit to stand test and walk test, and in 10 dogs with unilateral cranial cruciate ligament rupture and 18 non-lame dogs. Data collected were used to calculate symmetry indices (SI) of ipsilateral and contralateral hindlimbs (HL), diagonal limb pairs (DLP) and ipsilateral limb pairs (ILP). RESULTS The symmetry indices of peak vertical force of HL during the walk test and sit to stand test were 100% and 90% sensitive for discriminating lame and non-lame dogs respectively. The symmetry indices of vertical impulse of HLs during the walk test and sit to stand test were 100% and 50% sensitive for discriminating lame and non-lame dogs respectively. Analysis of ipsilateral and diagonal limb pairs did not improve the discrimination in either test. The time taken to collect data from the sit to stand test data was shorter than for the walk test. CLINICAL SIGNIFICANCE Whilst the sit to stand test required a shorter time for collection of data than the walk test, it did not accurately identify all dogs with lameness associated with CCLR, and thus has relatively limited clinical utility in its tested form.

Abstract
BACKGROUND Favorable 6-month outcomes from the CLASP IID Registry (Edwards PASCAL transcatheter valve repair system pivotal clinical trial) demonstrated that mitral valve transcatheter edge-to-edge repair with the PASCAL transcatheter valve repair system is safe and beneficial for treating prohibitive surgical risk degenerative mitral regurgitation (DMR) patients with complex mitral valve anatomy. OBJECTIVES The authors sought to assess 1-year safety, echocardiographic and clinical outcomes from the CLASP IID Registry. METHODS Patients with 3+ or 4+ DMR who were at prohibitive surgical risk, had complex mitral valve anatomy based on the MitraClip Instructions for Use, and deemed suitable for treatment with the PASCAL system were enrolled prospectively. Safety, clinical, echocardiographic, functional, and quality-of-life outcomes were assessed at 1 year. Study oversight included a central screening committee, echocardiographic core laboratory, and clinical events committee. RESULTS Ninety-eight patients were enrolled. One-year Kaplan-Meier (KM) estimates of freedom from composite major adverse events, all-cause mortality, and heart failure hospitalization were 83.5%, 89.3%, and 91.5%, respectively. Significant mitral regurgitation (MR) reduction was achieved at 1 year (P < 0.001 vs baseline) including 93.2% at MR ≤2+ and 57.6% at MR ≤1+ with improvements in related echocardiographic measures. NYHA functional class and Kansas City Cardiomyopathy Questionnaire score also improved significantly (P < 0.001 vs baseline). CONCLUSIONS At 1 year, treatment with the PASCAL system demonstrated safety and significant MR reduction, with continued improvement in clinical, echocardiographic, functional, and quality-of-life outcomes, illustrating the value of the PASCAL system in the treatment of prohibitive surgical risk patients with 3+ or 4+ DMR and complex mitral valve anatomy.

Abstract
BACKGROUND Persistent multi-organ symptoms after COVID-19 have been termed "long COVID" or "post-acute sequelae of SARS-CoV-2 infection" (PASC). The complexity of these clinical manifestations posed challenges early in the pandemic as different ambulatory models formed out of necessity to manage the influx of patients. Little is known about the characteristics and outcomes of patients seeking care at multidisciplinary post-COVID centers. METHODS We performed a retrospective cohort study of patients evaluated at our multidisciplinary Comprehensive COVID-19 Center (CCC) in Chicago, IL, between May 2020 and February 2022. We analyzed specialty clinic utilization and clinical test results according to severity of acute COVID-19. RESULTS We evaluated 1802 patients a median of 8 months from acute COVID-19 onset, including 350 post-hospitalization and 1452 non-hospitalized patients. Patients were seen in 2361 initial visits in 12 specialty clinics, with 1151 (48.8%) in neurology, 591 (25%) in pulmonology, and 284 (12%) in cardiology. Among patients tested, 742/878(85%) reported decreased quality of life, 284/553(51%) had cognitive impairment, 195/434(44.9%) had alteration of lung function, 249/299(83.3%) had abnormal CT chest scans, and 14/116(12.1%) had elevated heart rate on rhythm monitoring. Frequency of cognitive impairment and pulmonary dysfunction was associated with severity of acute COVID-19. Non-hospitalized patients with positive SARS-CoV-2 testing had similar findings than those with negative or no test results. CONCLUSIONS The CCC experience shows common utilization of multiple specialists by long COVID patients, who harbor frequent neurologic, pulmonary, and cardiologic abnormalities. Differences in post-hospitalization and non-hospitalized groups suggest distinct pathogenic mechanisms of long COVID in these populations.

Abstract
The gut-brain axis plays an important role in bidirectional communication that exists and can be altered by injury. Neurotrauma provides acute alteration in the GI tract and alters autonomic function. In this focused review, we highlight what is known about GI disruption following neurotrauma. We then delve into how this affects recovery. Areas of innovation and emerging pre-clinical results are addressed. Finally, we address the link between neurotrauma induced GI dysfunction and progression to neurodegenerative disease states.

Abstract
Patients with severe symptomatic tricuspid regurgitation face a significant dilemma in treatment options, as the yearly mortality with medical therapy and the surgical mortality for tricuspid repair or replacement are high. Transcatheter edge-to-edge repair (TEER) for the tricuspid valve is becoming a viable option in patients, although procedural success is dependent on high-quality imaging. While transesophageal echocardiography remains the standard for tricuspid TEER procedures, intracardiac echocardiography (ICE) with three-dimensional (3D) multiplanar reconstruction (MPR) has many theoretical and practical advantages. The aim of this article was to describe the in vitro wet lab-based imaging work done to facilitate the best approach to 3D MPR ICE imaging and the procedural experience gained with 3D MPR ICE in tricuspid TEER procedures with the PASCAL device.

Abstract
Abstract
Introduction
Within the Geriatric Medicine department at the Lister Hospital, Stevenage, the timeliness and quality of discharge summaries had become a source of complaints. Both primary care practitioners and families reported documentation was inadequate or incorrect. This project aimed to improve the quality of these discharge summaries in accordance with standards generated from previous audit data. Through improving communication it was clear that patient care could be enhanced.
Methods
Each month 15 discharge summaries were selected at random for review. Alongside patient notes these summaries were appraised in regards to standard discharge summary requirements: timeliness of delivery; adequate description of admission; and documentation of the follow up plan. They were also appraised on documentation of specific requirements for older aged adults including cognitive status, mobility status, discharge destination, need for home help, Rockwood Frailty score and resuscitation and escalation plans. Interventions including informal communication with junior doctors, circulation of a ‘Top Tips’ sheet, generation of an information poster and dissemination of information at local teaching sessions, took place, and were assessed, over regular PDSA cycles.
Results
showed a clear, sustained improvement in the quality of the discharge summaries. At the end of data collection, 100% of discharge summaries contained an adequate description of admission and an appropriate follow up plan. There was also significant improvement in documentation of specific requirements. Where documentation was initially very limited, following interventions, most discharge summaries contained details pertaining to discharge destination, need for home support, mobility status and resuscitation and escalation plans.
Conclusion
The relatively simple interventions have been found to have a sustained improvement in the quality of discharge summaries from the Geriatric Medicine Department at Lister Hospital, Stevenage. Whilst more work needs to be done it is hoped that this will already have enhanced patient care.

Abstract
Lateral flow immunoassays (LFIs) are simple, point-of-care diagnostic devices used for detecting biological agents or other analytes of interest in a sample. LFIs are predominantly singleplex assays, interrogating one target analyte at a time. There is a need for multiplex LFI devices, e.g., a syndromic panel to differentiate pathogens causing diseases exhibiting similar symptoms. Multiplex LFI devices would be especially valuable in instances where sample quantity is limiting and reducing assay time and costs is critical. There are limitations to the design parameters and performance characteristics of a multiplex LFI assay with many horizontal test lines due to constraints in capillary flow dynamics. To address some of the performance issues, we have developed a spot array multiplex LFI using Braille format (hence called Blind Spot) and a sensor, MACAW (Modular Automated Colorimetric Analyses Widget), that can analyze and interpret the results. As a proof of concept, we created a multiplex toxin panel, for detecting three toxins, using two letter codes for each. The results indicated that the six-plex, triple toxin assay performs as well as singleplex assays. The sensor-based calls are better compared to human interpretation in discriminating and interpreting ambiguous test results correctly especially at lower antigen concentrations and from strips with blemishes.

Abstract
OBJECTIVES We report the 30-day outcomes from the roll-in cohort of the CLASP IID trial, representing the first procedures performed by each site. BACKGROUND The currently enrolling CLASP IID/IIF pivotal trial is a multicenter, prospective, randomized trial assessing the safety and effectiveness of the PASCAL transcatheter valve repair system in patients with clinically significant MR. The trial allows for up to three roll-in patients per site. METHODS Eligibility criteria were: DMR ≥3+, prohibitive surgical risk, and deemed suitable for transcatheter repair by the local heart team. Trial oversight included a central screening committee and echocardiographic core laboratory. The primary safety endpoint was a 30-day composite MAE: cardiovascular mortality, stroke, myocardial infarction (MI), new need for renal replacement therapy, severe bleeding, and non-elective mitral valve re-intervention, adjudicated by an independent clinical events committee. Thirty-day echocardiographic, functional, and quality of life outcomes were assessed. RESULTS A total of 45 roll-in patients with mean age of 83 years and 69% in NYHA class III/IV were treated. Successful implantation was achieved in 100%. The 30-day composite MAE rate was 8.9% including one cardiovascular death (2.2%) due to severe bleeding from a hemorrhagic stroke, one MI, and no need for re-intervention. MR≤1+ was achieved in 73% and ≤2+ in 98% of patients. 89% of patients were in NYHA class I/II (p < .001) with improvements in 6MWD (30 m; p = .054) and KCCQ (17 points; p < .001). CONCLUSIONS Early results representing sites with first experience with the PASCAL repair system showed favorable 30-day outcomes in patients with DMR≥3+ at prohibitive surgical risk.

Abstract
Importance The frequency of baseline renal impairment among high-risk and inoperable patients with severe aortic stenosis undergoing a transcatheter aortic valve replacement (TAVR) and the effect of TAVR on subsequent renal function are, to our knowledge, unknown. Objective To determine the effect of TAVR among patients with baseline renal impairment. Design, Setting, and Participants This substudy of patients with baseline renal impairment (estimated glomerular filtration rate [eGFR] ≤ 60 mL/min) and paired baseline and 30-day measures of renal function undergoing TAVR in the PARTNER 1 trial and continued access registries was conducted in 25 centers in the United States and Canada. Main Outcomes and Measures Patients were categorized with improved eGFR (30-day follow-up eGFR≥10% higher than baseline pre-TAVR), worsened eGFR (≥10% lower), or no change in renal function (neither). Baseline characteristics, 30-day to 1-year all-cause mortality, and repeat hospitalization were compared. Multivariable models were constructed to identify predictors of 1-year mortality and of improvement/worsening in eGFR. Results Of the 821 participants, 401 (48.8%) were women and the mean (SD) age for participants with improved, unchanged, or worsening eGFR was 84.90 (6.91) years, 84.37 (7.13) years, and 85.39 (6.40) years, respectively. The eGFR was 60 mL/min or lower among 821 patients (72%), of whom 345 (42%) improved, 196 (24%) worsened, and 280 (34%) had no change at 30 days. There were no differences in baseline age, body mass index, diabetes, chronic obstructive pulmonary disease, coronary artery disease, peripheral arterial disease, hypertension, pulmonary hypertension, renal or liver disease, New York Heart Association III/IV symptoms, transaortic gradient, left ventricular ejection fraction, or procedural characteristics. The group with improved eGFR had more women, nonsmokers, and a lower cardiac index. Those with worsening eGFR had a higher median Society of Thoracic Surgeons score and left ventricle mass. From 30 days to 1 year, those with improved eGFR had no difference in mortality or repeat hospitalization. Those with worsening eGFR had increased mortality (25.5% vs 19.1%, P = .07) but no significant increases in repeat hospitalization or dialysis. Predictors of improved eGFR were being female (odds ratio [OR], 1.38; 95% CI, 1.03-1.85; P = .03) and nonsmoking status (OR, 1.49; 95% CI, 1.11-1.01; P = .01); predictors of worsening eGFR were baseline left ventricle mass (OR, 1.00; 95% CI, 1.00-1.01; P = .01), smoking (OR, 1.51; 95% CI, 1.06-2.14; P = .02), and age (OR, 1.03; 95% CI, 1.00-1.05; P = .05); and predictors of 1-year mortality were baseline left ventricular ejection fraction (OR, 0.98; 95% CI, 0.97-0.99; P = .003), baseline eGFR (OR, 0.98; 95% CI, 0.96-0.99; P < .001), and worsening eGFR vs no change in eGFR (OR, 1.51; 95% CI, 1.02-2.24; P = .04). Conclusions and Relevance Baseline renal impairment was frequent among patients who underwent TAVR. While improved eGFR did not improve 1-year outcomes, worsening eGFR was associated with increased mortality. Trial Registration clinicaltrials.gov Identifier: NCT00530894.

Abstract
OBJECTIVE To evaluate the impact of a standardized surgical technique for primary cesarean deliveries (CDs) on operative time and surgical morbidity. MATERIALS AND METHODS Two-year retrospective chart review of primary CD performed around the implementation of a standardized CD surgical technique. The primary outcome was total operative time (TOT). Secondary outcomes included incision-to-delivery time (ITDT), surgical site infection, blood loss, and maternal and fetal injuries. RESULTS When comparing pre- versus postimplementation surgical times, there was no significant difference in TOT (76.5 vs. 75.9 minutes, respectively; p = 0.42) or ITDT (9.8 vs. 8.8 minutes, respectively; p = 0.06) when the entire cohort was analyzed. Subgroup analysis of CD performed early versus late in an academic year among the pre- and postimplementation groups showed no significant difference in TOT (79.3 early vs. 73.8 minutes late; p = 0.10) or ITDT (10.8 early vs. 8.8 minutes late; p = 0.06) within the preimplementation group. In the postimplementation group, however, there was significant decrease in TOT (80.5 early vs. 71.3 minutes late; p = 0.02) and ITDT (10.6 early vs. 6.8 minutes late; p < 0.01). Secondary outcomes were similar for both groups. CONCLUSION A standardized surgical technique combined with surgical experience can decrease TOT and ITDT in primary CD without increasing maternal morbidity.

Abstract
BACKGROUND Proteinase-Activated Receptor-2 (PAR2 ) is a G protein-coupled receptor activated by serine proteinases. We have shown that PAR2 activation in the airways is involved in the development of allergic inflammation and airway hyperresponsiveness (AHR) in acute murine models. We hypothesized that functional inhibition of PAR2 prevents allergic inflammation, AHR and airway remodeling in chronic allergic airway inflammation models. MATERIAL AND METHODS We developed and used a 12 week model of cockroach extract (CE)-mediated AHR, airway inflammation and remodeling in BALB/c mice. RESULTS Mice sensitized and challenged with CE for 12 weeks exhibit AHR, increased numbers of eosinophils in bronchoalveolar lavage (BAL) and increased collagen content in the lung tissue compared to saline controls. Administration of an anti-PAR2 antibody, SAM-11, after the initial development of airway inflammation significantly inhibited all these parameters. CONCLUSIONS Our data demonstrate that PAR2 signaling plays a key role in CE-induced AHR and airway inflammation/remodeling in long term models of allergic airway inflammation. Targeting PAR2 activation may be a successful therapeutic strategy for allergic asthma.

Abstract
BACKGROUND New Zealand has among the highest rates of colorectal cancer in the world and is an unscreened population. The aim of this study was to determine the trends in incidence and tumour location in the New Zealand population before the introduction of national colorectal cancer screening. METHODS Data were obtained from the national cancer registry and linked to population data from 1995 to 2012. Incidence rates for colorectal cancer by sex, age (less than 50 years, 50-79 years, 80 years or more) and location (proximal colon, distal colon and rectum) were assessed by linear regression. RESULTS Among patients aged under 50 years, the incidence of distal colonic cancer in men increased by 14 per cent per decade (incidence rate ratio (IRR 1·14), 95 per cent c.i. 1·00 to 1·30; P = 0·042); the incidence of rectal cancer in men increased by 18 per cent (IRR 1·18, 1·06 to 1·32; P = 0·002) and that in women by 13 per cent (IRR 1·13, 1·02 to 1·26; P = 0·023). In those aged 50-79 years, there was a reduction in incidence per decade of proximal, distal and rectal cancers in both sexes. In the group aged 80 years and over, proximal cancer incidence per decade increased by 19 per cent in women (IRR 1·19, 1·13 to 1·26; P < 0·001) and by 25 per cent in men (IRR 1·25, 1·18 to 1·32; P < 0·001); among women, the incidence of distal colonic cancer decreased by 8 per cent (IRR 0·92, 0·86 to 0·98); P = 0·012), as did that of rectal cancer (IRR 0·92, 0·86 to 0·97; P = 0·005). CONCLUSION The increasing incidence of rectal cancer among younger patients needs to be considered when implementing screening strategies.

Abstract
Background:
Co-management of hospitalized heart failure (HHF) patients by hospitalists and cardiologists may enhance care quality. Aided by an enterprise data warehouse (EDW) screen for HHF patients, we implemented a house surveillance model of heart failure consultation, whereby cardiology consultation and multidisciplinary heart failure intervention was offered for patients meeting criteria.
Objective:
To analyze the impact of house surveillance for HHF on cardiology consultation rates for patients coding into heart failure diagnosis-related groups (DRGs) on medicine units.
Methods:
An EDW screen for HHF was deployed, and services with HHF patients were offered cardiology consultation. The intervention was deployed 7/2015; chart review for patients 6 months pre- and post-intervention was conducted to ascertain consultation rate.
Results:
There were 386 patient discharges from a non-cardiac service with a heart failure DRG. In the six months prior to intervention, 40% of patients had cardiology consultation. This figure rose to 69% post-intervention, a highly statistically significant result.
Conclusions:
EDW-enabled active surveillance for HHF increases cardiology consultation rate, allowing for multidisciplinary intervention, co-management, and potentially improved outcomes for HHF patients.

Abstract
BACKGROUND Proteinase-activated receptor 2 (PAR2 ) is a G protein-coupled receptor activated by trypsin-like serine proteinases. PAR2 activation has been associated with inflammation including allergic airway inflammation. We have also shown that PAR2 activation in the airways leads to allergic sensitization. The exact contribution of PAR2 in the development of eosinophilic inflammation and airway hyperresponsiveness (AHR) in sensitized individuals is not clear. OBJECTIVE To investigate whether functional inhibition of PAR2 during allergen challenge of allergic mice would inhibit allergen-induced AHR and inflammation in mouse models of asthma. METHODS Mice were sensitized and challenged with ovalbumin (OVA) or cockroach extract (CE). To investigate the role of PAR2 in the development of AHR and airway inflammation, we administered blocking anti-PAR2 antibodies, or a cell permeable peptide inhibitor of PAR2 signalling, pepducin, i.n. before allergen challenges and then assessed AHR and airway inflammation. RESULTS Administration of anti-PAR2 antibodies significantly inhibited OVA- and CE-induced AHR and airway inflammation. In particular, two anti-PAR2 antibodies, the monoclonal SAM-11 and polyclonal B5, inhibited AHR, airway eosinophilia, the increase of cytokines in the lung tissue and antigen-specific T cell proliferation, but had no effect on antigen-specific IgG and IgE levels. Pepducin was also effective in inhibiting AHR and airway inflammation in an OVA model of allergic airway inflammation. CONCLUSIONS AND CLINICAL RELEVANCE Functional blockade of PAR2 in the airways during allergen challenge improves allergen-induced AHR and inflammation in mice. Therefore, topical PAR2 blockade in the airways, through anti-PAR2 antibodies or molecules that interrupt PAR2 signalling, has the potential to be used as a therapeutic option in allergic asthma.
