Critical Care of the Burn Patient.

Care of the critically ill burned patient must integrate a multidisciplinary care team composed of burn care specialists. As resuscitative mortality decreases more patients are surviving to experience multisystem organ failure relating to complications of their injuries. Clinicians must be aware of physiologic changes following burn injury and the implicated impacts on management strategy. Promoting wound closure and rehabilitation should be the backdrop for which management decisions are made.

Emphysematous osteomyelitis of the calcaneus: a case report and review.

Emphysematous osteomyelitis is a rare but potentially fatal condition, which classically features intraosseous air on imaging without a direct communication with the atmosphere. Prompt recognition and treatment of the disease cannot be overstated as there is a high mortality rate associated with this condition. Here we report a case of emphysematous osteomyelitis of the calcaneus in a sixty-one-year-old male with diabetes mellitus and end-stage renal disease. This case of osteomyelitis was associated with an overlying necrotizing soft tissue infection, mandating an urgent below-knee amputation for source control. This case report is the first of its kind in the literature involving the calcaneous as emphysematous osteomyelitis more commonly involves the vertebral column. The purpose of this case report is to discuss the presentation and treatment of emphysematous osteomyelitis involving the calcaneous as well as provide a review of the current literature on this diagnosis.

A Teachable Moment: Colorectal Cancer Screening Among Companions Waiting for Outpatients Undergoing a Colonoscopy.

To determine colorectal cancer (CRC) screening knowledge, attitudes, behaviors, and preferences for a future CRC screening educational intervention among adults (companions) waiting for outpatients undergoing a colonoscopy. We approached 384 companions at three endoscopy centers associated with one healthcare system to complete a survey from March to July 2017. The survey assessed CRC and CRC screening knowledge, attitudes, behaviors, and preferences for a future CRC screening educational intervention. There were 164 companions at average risk for CRC that completed a self-administered survey. Among average-risk companions, 23% were not within screening guidelines. Additionally, 74% of those not within guidelines reported that they had never completed a CRC screening test. The most frequently reported barriers to CRC screening were the perception of not needing screening because they were asymptomatic and lack of a provider recommendation for screening. Companions suggested that a future CRC screening intervention include a brochure and/or a brief video, featuring men and women from different races/ethnicities, a CRC survivor, and a healthcare professional. Almost one-fourth of average-risk companions waiting at endoscopy centers were not within CRC screening guidelines, providing a teachable moment to recruit companions to participate in an educational intervention to encourage screening. Companions provided suggestions (e.g., content and channel) for a future intervention to promote CRC screening in this population.

Does Enzymatic Debridement Allow Us To Perform Conservative Treatment On Clinically Deep Hand Burns? A Retrospective Review.

The hands are one of the main locations of burns. In deep second-degree and third-degree burns, the gold standard of treatment is surgical debridement and subsequent coverage, which can result in suboptimal aesthetic and functional results. The aim of our study is to assess whether treatment by initial enzymatic debridement (NexoBrid®) of deep second-degree and third-degree burns prevents the need for surgery. We carried out a retrospective study of 53 hands with deep burns treated in our centre from May 2015 to December 2016. Two experts evaluated the initial photographs of the burns and classified them as surgical or nonsurgical (interobserver kappa index = 0.83). These assessments were compared with the actual need for surgery on each hand. Sixteen of the 32 (50%) hands that the experts considered surgical spontaneously epithelialized. Four of the 17 hands (23.5%) that were not considered surgical required a split-thickness skin graft for healing. Enzymatic debridement helps to preserve viable tissue, which reduces the number and extension of surgical interventions, thus favouring better results.

Les mains sont une des principales localisations de brûlures. Dans les brûlures du 2e degré profond et du 3e degré, le traitement de référence est l'excision chirurgicale suivie d'un geste de couverture, et donne des résultats fonctionnels ou esthétiques pas toujours parfaits. Le but de notre étude est d'évaluer si le débridement enzymatique (NexoBrid®) des brûlures du 2e degré profond et du 3e degré permet d'éviter les gestes chirurgicaux. Nous avons mené une étude rétrospective sur 53 mains présentant des brûlures profondes traitées dans notre centre entre mai 2004 et décembre 2016. Deux experts ont évalué les photographies initiales et classé les brûlures en « chirurgicales ¼ ou « non chirurgicales ¼ (coefficient Kappa inter-opérateur = 0,83). Ces évaluations ont été comparées à la nécessité réelle de prise en charge chirurgicale pour chacune des mains. 16 des 32 mains (50%) que les experts avaient jugées « chirurgicales ¼ ont cicatrisé spontanément. 4 des 17 mains (23,5%) qui ont été considérée comme « non chirurgicales ¼ ont nécessité une greffe de peau mince pour obtenir la cicatrisation. Le débridement enzymatique permet de conserver les tissus viables, ce qui diminue le nombre et l'importance des gestes chirurgicaux, et donc favorise l'obtention de meilleurs résultats.

Validation and preliminary data from a health-related quality of life questionnaire for owners of dogs with cardiac disease.

BACKGROUND: Cardiac disease in dogs impacts the quality of life (QoL) of their owners, but owners' QoL has not been comprehensively assessed in this population. OBJECTIVES: To develop, validate, and provide preliminary data from a health-related QoL (hrQoL) questionnaire for owners of dogs with cardiac disease. SUBJECTS: A total of 141 owners of dogs with cardiac disease were studied. METHODS: An owner hrQoL (O-hrQoL) questionnaire containing 20 items related to areas of a person's life that could be impacted by caring for a dog with cardiac disease was developed and administered to owners of dogs with cardiac disease. The highest possible total score was 100, with higher scores indicating a worse hrQoL. Readability, internal consistency, face and construct validity, and item-total correlations were assessed. RESULTS: Median O-hrQoL score was 35 (range, 0-87). The questionnaire had good internal consistency (Cronbach's α = 0.933), construct validity (Spearman's r = 0.38-0.53; Kendall's τ = 0.30-0.43; P < .001), and item-total correlation (Spearman's r = 0.44-0.79; Kendall's τ = 0.34-0.66; all P < .001). Fifty percent of owners indicated a negative effect of dogs' cardiac disease on their own QoL, but all owners responded that caring for their dogs either had strengthened (n = 76; 53.9%) or had no effect on their relationship with their dog (n = 65; 46.1%). CONCLUSIONS AND CLINICAL IMPORTANCE: The O-hrQoL questionnaire had good validity, and results suggest that owners' QoL is significantly impacted by caring for dogs with cardiac disease. Additional research on effective approaches to minimizing the negative effects of a dog's cardiac disease on the owner is warranted.

Extracellular vesicular microRNAs as potential biomarker for early detection of doxorubicin-induced cardiotoxicity.

BACKGROUND: Long-term use of doxorubicin (DOX) is limited by cumulative dose-dependent cardiotoxicity. OBJECTIVES: Identify plasma extracellular vesicle (EV)-associated microRNAs (miRNAs) as a biomarker for cardiotoxicity in dogs by correlating changes with cardiac troponin I (cTnI) concentrations and, echocardiographic and histologic findings. ANIMALS: Prospective study of 9 client-owned dogs diagnosed with sarcoma and receiving DOX single-agent chemotherapy (total of 5 DOX treatments). Dogs with clinically relevant metastatic disease, preexisting heart disease, or breeds predisposed to cardiomyopathy were excluded. METHODS: Serum concentration of cTnI was monitored before each treatment and 1 month after the treatment completion. Echocardiography was performed before treatments 1, 3, 5, and 1 month after completion. The EV-miRNA was isolated and sequenced before treatments 1 and 3, and 1 month after completion. RESULTS: Linear mixed model analysis for repeated measurements was used to evaluate the effect of DOX. The miR-107 (P = .03) and miR-146a (P = .02) were significantly downregulated whereas miR-502 (P = .02) was upregulated. Changes in miR-502 were significant before administration of the third chemotherapeutic dose. When stratifying miRNA expression for change in left ventricular ejection fraction, upregulation of miR-181d was noted (P = .01). Serum concentration of cTnI changed significantly but only 1 month after treatment completion, and concentrations correlated with left ventricular ejection fraction and left ventricular internal dimension in diastole. CONCLUSION AND CLINICAL SIGNIFICANCE: Downregulation of miR-502 was detected before significant changes in cTnI concentrations or echocardiographic parameters. Further validation using a larger sample size will be required.

Extensively drug-resistant Pseudomonas Aeruginosa outbreak in a burn unit: management and solutions.

Infections are still the main cause of mortality in burn patients. Multidrug resistant bacteria can cause outbreaks in critical care and burn units. We describe an outbreak of infection by extensively drug-resistant Pseudomonas aeruginosa in the Burn Unit of a University Hospital in Barcelona (Spain) between April and July 2016. A descriptive study of all cases, a bacterial colonization screening of all admitted patients and a microbiological environmental study were performed in order to detect a possible common focus. Contact isolation and cohortization of healthcare workers of all infected or colonized patients were applied. Environmental control measures were instituted for possible sources of infection. The outbreak was caused by a strain of P. aeruginosa only sensitive to colistin. Ten patients were infected or colonized and two of them died. The same strain was detected in several taps and drains in different rooms of the Unit. After applying control measures, changing faucets and drains, carrying out thermal disinfection of the hot water installation of the unit, disinfecting the rooms with ultraviolet radiation and placing antibacterial filtration devices in all the taps among other measures, an effective control of the outbreak was achieved.

Les infections sont toujours une cause majeure de mortalité chez les brûlés. Des épidémies à bactéries multirésistantes (BMR) dans les CTB sont régulièrement rapportées. Nous décrivons une épidémie due à Pseudomonas æruginosa BMR, sensible uniquement à la colimycine, survenue dans le CTB d'un hôpital universitaire de Barcelone entre avril et juillet 2016. Elle a touché 10 patients dont 2 sont morts. Une étude de chaque cas, un dépistage chez tous les entrants et une étude environnementale ont été réalisées, afin de trouver d'éventuelles similitudes. Un isolement contact et un cohorting ont été mis en place. Des mesures de contrôle de l'environnement ont été implémentées. La souche incriminée a été retrouvée dans plusieurs robinets et siphons du service. Cette épidémie a été résolue après, outre les mesures précitées, changement des robinets et des siphons (avec mise en place d'ultrafiltres sur les robinets), choc thermique du réseau d'adduction d'eau, désinfection terminale UV des chambres.

Evaluation of head impact exposure measured from youth football game plays.

OBJECTIVE: There is a growing body of literature informing efforts to improve the safety of football; however, research relating on-field activity to head impacts in youth football is limited. Therefore, the objective of this study was to compare head impact exposure (HIE) measured in game plays among 3 youth football teams. METHODS: Head impact and video data were collected from athletes (ages 10-13 years) participating on 3 youth football teams. Video analysis was performed to verify head impacts and assign each to a specific play type. Each play was categorized as a down, punt, kickoff, field goal, or false start. Kickoffs and punts were classified as special teams. Downs were classified as running, passing, or other. HIE was quantified by play type in terms of mean, median, and 95th percentile linear and rotational acceleration. Mixed-effects models were used to assess differences in acceleration among play types. Contact occurring on special teams plays was evaluated using a standardized video abstraction form. RESULTS: A total of 3003 head impacts over 27.5 games were analyzed and paired with detailed video coding of plays. Most head impacts were attributed to running (79.6%), followed by passing (14.0%), and special teams (6.4%) plays. The 95th percentile linear acceleration measured during each play type was 52.6g, 50.7g, and 65.5g, respectively. Special teams had significantly greater mean linear acceleration than running and passing plays (both p = 0.03). The most common kick result on special teams was a deep kick, of which 85% were attempted to be returned. No special teams plays resulted in a touchback, and one resulted in a fair catch. One-third of all special teams plays and 92% of all nonreturned kicks resulted in athletes diving toward the ball. CONCLUSIONS: The results demonstrate a trend toward higher head impact magnitudes on special teams than for running and passing plays, but a greater number of impacts were measured during running plays. Deep kicks were most common on special teams, and many returned and nonreturned kicks resulted in athletes diving toward the ball. These results support policy changes to youth special teams plays, including modifying the yard line the ball is kicked from and coaching proper return technique. Further investigation into biomechanical exposure measured during game impact scenarios is needed to inform policy relevant to the youth level.

Assessing Colorectal Cancer Screening Barriers by Two Methods.

Colorectal cancer (CRC) is commonly diagnosed in the USA despite screening tests that have decreased CRC incidence and mortality. Finding the best method to identify patient-level screening barriers is important to improve CRC screening rates. A group-randomized trial was conducted among ten primary-care clinics. Clinics were randomized to a multi-level (clinic, provider, patient) CRC screening intervention or usual care (2007-2013). Subsequent to clinic- and provider-level interventions, a three-step, patient-level intervention was conducted. One step of the patient-level intervention was a CRC screening barriers counseling call conducted by a lay health advisor (LHA). During the call, two methods were used to identify CRC screening barriers. An open-ended question was used first to determine why participants had not completed screening (without probes). Subsequently, the LHA read a list of additional potential screening barriers and asked participants whether each barrier was applicable (with probes). A generalized estimating equation approach was used to compare the two methods. Participants (n = 109) were female (59%), had a mean age of 57.2 years, and were white (67%) or black (31%). Most participants had some college education or a college degree (79%), annual household income $30,000+ (60%), and health insurance (80%). The number of CRC screening barriers increased with probing compared to the open-ended question format (OR 2.10, 95% CI 1.92-2.31; p < 0.01). The ranking of reported CRC screening barriers did not vary by assessment method. However, the methodology used to document CRC screening barriers may influence the content of patient-directed interventions.

Histiocytoses: emerging neoplasia behind inflammation.

Histiocytoses are disorders characterised by inflammation and the accumulation of cells derived from the monocyte and macrophage lineages, which results in tissue damage. Although they are often considered rare disorders with protean clinical manifestations, considerable advances in the understanding of their genetics have led to increased clinical recognition of these conditions, and fuelled further insights into their pathogenesis. In this Review, we describe insights into the cells of origin, molecular pathology, clinical features, and treatment strategies for some of the most common histiocytic disorders, including Langerhans cell histiocytosis, Erdheim-Chester disease, and Rosai-Dorfman disease. With the discovery of recurrent mutations affecting the mitogen-activated protein kinase and mTOR-AKT pathways in some of these histiocytoses, our understanding of these diseases has now evolved from the concept of a primary inflammatory condition to that of a clonal neoplastic disease. This understanding has led to the development of effective mechanism-based therapeutic strategies for patients with histiocytic diseases.

Functional reconstruction of acutely burnt achilles tendon with composite anterolateral thigh flap with fascia lata: a case report.

Soft tissue defects in the postero-inferior aspect of the leg are still challenging, especially when they affect the Achilles tendon due to its important functional involvement in the normal movement of the ankle. Dorsiflexion and flexion may be affected if proper reconstruction is not achieved, thus limiting daily activities such as walking, climbing stairs or running. Several techniques, including local or regional flaps, combinations of tendon substitutes with free muscular or fasciocutaneous flaps, and free composite flaps with tendon have been described for the reconstruction of complex defects caused by burn sequelae, tumors, trauma, chronic ulcers, etc. The gold standard treatment for moderate to large defects is the anterolateral thigh (ALT) flap with vascularized fascia lata. The ALT flap is reliable because of a long vascular pedicle and a large donor area. Moreover, the fascia lata mimics the Achilles tendon perfectly when rolled on itself. The aim of this article is to present the application of this technique for the first time in a case of an acute burn. The timing of reconstruction with free flaps is critical in acute burns. In our case, it was performed on the 24th day post-burn and no microsurgical complications appeared. More than six months after surgery, the patient showed a normal gait, was able to lift his own weight against gravity and no complications were detected in the donor area.

Les pertes de substance des parties molles de la région postéro inférieure de jambe constituent un problème majeur, surtout quand elles intéressent le tendon d'Achille, à cause de son importante implication dans les mouvements normaux de la cheville. La dorsiflexion et la flexion peuvent être affectées si une réparation correcte n'est pas réalisée, car elle limite les activités journalières telles que la marche, la montée d'escaliers, ou la course. Plusieurs techniques incluant les lambeaux locaux et régionaux, l'association de substituts tendineux avec des lambeaux libres musculaires ou fascio cutanés, et les lambeaux libres composites avec tendon ont été décrits pour la reconstruction des pertes de substances complexes en rapport avec séquelles de brûlures, tumeurs, traumatismes, ulcères chroniques etc. Le traitement de référence pour des pertes de substances modérées ou importantes est constitué par le lambeau antero latéral de cuisse avec fascia lata vascularisé. Ce lambeau est sûr, du fait du long pédicule vasculaire et de l'importance de la surface de la zone donneuse. Cependant, le fascia lata imite parfaitement le tendon d'Achille, que s'il est roulé sur lui-même. Le but de cet article est de présenter une application de cette technique pour la première fois dans un cas de brûlures en urgence. Le moment de la reconstruction par lambeaux libres est discuté dans les brûlures. Dans notre observation, il a été réalisé au cours du 24 e jour après la brûlure et sans complications micro chirurgicales. Plus de six mois après la chirurgie, le patient affiche une démarche normale, il est capable de se lever tout seul et aucune complication n'est apparue au niveau de la zone donneuse.

Perspectives from health-care providers and women about completing human papillomavirus (HPV) self-testing at home.

Cervical cancer (CC) incidence and mortality rates are increased, and CC screening rates are low among Appalachian Ohio women. Mailing human papillomavirus (HPV) self-tests to women to complete at home is a potential new strategy to engage women in CC screening. The authors aimed to gain insights into the perceived acceptability of mailed HPV self-tests. Focus groups were conducted (August 2014-January 2015) among providers (physicians, nurse practitioners, nurses) and women in Appalachian Ohio. Providers (n = 28) and women (n = 15; age range: 32-62 years) reported general acceptance of HPV self-tests, however, for different reasons. Providers thought HPV self-testing would increase the proportion of under-screened women returning to the health-care system, while women thought self-testing would eliminate logistical and reduce psychological CC screening barriers. Findings provide insights into facilitators and barriers of completing an HPV self-test at home, returning it, reporting results, and providing needed follow-up care. To the authors' knowledge, no systematic research exists addressing providers' views regarding women's use of HPV self-tests and the relation of such use to fostering subsequent Pap testing. This information will be useful in developing CC screening programs that include mailed HPV self-tests, as well as encouragement of follow-up Pap testing to meet existing CC screening guidelines.

Process Evaluation of Cancer Prevention Media Campaigns in Appalachian Ohio.

The purpose of this study is to provide process data from campaigns (2009-2010) to improve colorectal cancer (CRC; intervention) screening and fruit and vegetable (F&V; comparison) consumption in 12 Appalachian Ohio counties. County-specific campaigns included one billboard, posters, and articles for local newspapers. Participants in CRC screening counties who reported seeing CRC screening billboards had greater intention to talk to a doctor/nurse about screening in the next 6 months (odds ratio [OR] = 2.92, 95% confidence interval [CI; 1.71, 4.99]) and had twice the odds of talking to a doctor/nurse about screening in the past year (OR = 2.15, 95% CI [1.29, 3.60]) compared to those who did not see the billboards. Participants in F&V counties who reported seeing F&V billboards had twice the odds (OR = 2.27, 95% CI [1.35, 3.84]) of talking to a doctor/nurse in the past year about F&Vs compared to those who did not see the billboards. Participants who reported campaign exposure lived closer to the billboards compared to those who did not report campaign exposure (mean distance in miles from home to billboard: 8.8 vs. 10.9; p < .01). Most participants reported campaign messages were clear and important. Results suggest that partnering with community members to develop campaign materials is important to ensure cultural appropriateness and that exposure to the intervention components may affect health-related outcomes.

Fluid resuscitation management in patients with burns: update.

Since 1968, when Baxter and Shires developed the Parkland formula, little progress has been made in the field of fluid therapy for burn resuscitation, despite advances in haemodynamic monitoring, establishment of the 'goal-directed therapy' concept, and the development of new colloid and crystalloid solutions. Burn patients receive a larger amount of fluids in the first hours than any other trauma patients. Initial resuscitation is based on crystalloids because of the increased capillary permeability occurring during the first 24 h. After that time, some colloids, but not all, are accepted. Since the emergence of the Pharmacovigilance Risk Assessment Committee alert from the European Medicines Agency concerning hydroxyethyl starches, solutions containing this component are not recommended for burns. But the question is: what do we really know about fluid resuscitation in burns? To provide an answer, we carried out a non-systematic review to clarify how to quantify the amount of fluids needed, what the current evidence says about the available solutions, and which solution is the most appropriate for burn patients based on the available knowledge.

Electrical burns in times of economic crisis: A new epidemiologic profile.

Electrical injuries and especially those of high voltage still remain a source of high morbidity. Over the past few years, a change in the epidemiologic profile of these lesions was noticed at the Vall d'Hebron University Hospital Burn Unit, corresponding to an increase in cases out of the legal framework. It is our aim to describe this particular subset, to determine the extent of their injuries and to understand the reason for their increased incidence. We think this was favoured by the rise in the unemployment rate, along with higher copper prices.

Revised classification of histiocytoses and neoplasms of the macrophage-dendritic cell lineages.

The histiocytoses are rare disorders characterized by the accumulation of macrophage, dendritic cell, or monocyte-derived cells in various tissues and organs of children and adults. More than 100 different subtypes have been described, with a wide range of clinical manifestations, presentations, and histologies. Since the first classification in 1987, a number of new findings regarding the cellular origins, molecular pathology, and clinical features of histiocytic disorders have been identified. We propose herein a revision of the classification of histiocytoses based on histology, phenotype, molecular alterations, and clinical and imaging characteristics. This revised classification system consists of 5 groups of diseases: (1) Langerhans-related, (2) cutaneous and mucocutaneous, and (3) malignant histiocytoses as well as (4) Rosai-Dorfman disease and (5) hemophagocytic lymphohistiocytosis and macrophage activation syndrome. Herein, we provide guidelines and recommendations for diagnoses of these disorders.

Pilot study of a myostatin antagonist in dogs with cardiac cachexia.

OBJECTIVES: Cardiac cachexia, a loss of lean body mass caused by heart disease, often accompanies congestive heart failure (CHF). Blocking myostatin, which is a protein that inhibits muscle growth, appears to greatly enhance muscle size and strength in rodent models and human clinical trials. The objective of this study was to evaluate a dog-specific myostatin antagonist (CAP-031) in a pilot study to test its safety and efficacy in dogs with CHF and cardiac cachexia. ANIMALS: Dogs with CHF and cardiac cachexia. METHODS: Eligible dogs received four weekly subcutaneous injections of CAP-031. Endpoints were body weight, body condition score (BCS, on a 1-9 scale), muscle condition score (MCS, on a five-point scale, where 0 = no muscle loss and 4 = severe muscle loss), appetite, and a quality of life (QOL) score. RESULTS: Seven dogs with CHF and moderate-to-severe cachexia were enrolled in the study. For the six dogs that completed the study, the median age was 8.8 years (range 6.4-10.6). At baseline, the median body weight was 27.0 kg (range 17.3-62.0), the median BCS was 4 (2-5), and median MCS was 3 (3-4). There were no significant changes in body weight, BCS, appetite, or QOL score. The change in MCS (from a median of 3 at baseline to a median of 2.5 at week 4) was not statistically significant (p = 0.06). CONCLUSIONS: The myostatin antagonist appeared to be well tolerated in most dogs. Earlier identification of cachexia is important, and randomized, controlled trials of myostatin antagonists or other drugs to treat cardiac cachexia are needed.

Long-term outcome of physiologic VDD pacing versus non-physiologic VVI pacing in dogs with high-grade atrioventricular block.

OBJECTIVE: To compare the long-term outcome associated with physiologic VDD and non-physiologic VVI or VVIR pacing in dogs with high-grade atrioventricular block. ANIMALS: Forty-nine paced dogs with high-grade atrioventricular block were included. METHODS: Retrospective review of medical records, thoracic radiographs and echocardiograms for all dogs. Patient owners and referring veterinarians were contacted for survival times and a satisfaction questionnaire was submitted to the owners. Survival times, complication rates, resolution of clinical signs, and owner satisfaction were compared between the pacing modalities. RESULTS: A single lead VDD pacemaker was implanted in 19 dogs (39%) whereas 30 dogs (61%) were treated with VVI pacing. The median survival time for all dogs post-pacemaker implantation was 24.5 months. Survival time was significantly decreased in dogs that were older at the time of presentation or that presented with ventricular tachycardia or reduced left ventricular fractional shortening. Median survival times after implantation were not significantly different between pacing modalities (P = 0.29). Major complication rates were 11% within the VDD group and 20% within the VVI group and were not significantly different (P = 0.46). Minor complications were significantly higher within the VDD group than within the VVI group (47% versus 7% respectively; P < 0.01) due to a higher number of dogs in the VDD group experiencing transient ventricular premature contractions in the immediate post-implantation time period. Resolution of clinical signs, owner satisfaction, and quality of life perception were considered excellent in both groups. CONCLUSIONS: No long-term clinical benefit of VDD over VVI pacing could be identified in the present study.

Assessment of the responsiveness of the Cats' Assessment Tool for Cardiac Health (CATCH) Questionnaire.

OBJECTIVES: To evaluate the responsiveness and optimal timing of a validated health-related quality of life questionnaire, and to assess the relationship between quality of life, severity of disease, and N-terminal pro B-type natriuretic peptide (NT-proBNP) in cats with acute congestive heart failure (CHF). ANIMALS: Thirty client-owned cats with acute CHF. METHODS: Echocardiography, International Small Animal Cardiac Health Council (ISACHC) stage, and NT-proBNP were assessed in cats within 36 h of admission. The Cats' Assessment Tool for Cardiac Health (CATCH) Questionnaire (range of 0-80, with 80 being the worst possible score) was completed by cat owners and ISACHC stage was assessed at the time of hospital discharge, 3 days after discharge, and 7-14 days after discharge. NT-proBNP concentration was reassessed 7-14 days after discharge. RESULTS: The ISACHC stage at time of admission improved significantly by reevaluation 7-14 days after discharge (P < 0.001). The decrease in median NT-proBNP concentration from time of admission (655 pmol/L; range, 188 to >1500 pmol/L) to reevaluation (583 pmol/L; range, 41 to >1500 pmol/L) was not significant (P = 0.59). Median CATCH score was 26 (range, 0-70) at baseline, 19 (range, 0 to 61) at discharge, and 19 (range, 2-49) 7-14 days after discharge (P = 0.89). CATCH scores did not correlate with NT-proBNP concentrations or ISACHC stage. CONCLUSIONS: These results suggest that the CATCH questionnaire requires further refinement for uses requiring a responsive instrument in cats with acute CHF.
