The Text-Picture Integration Scale for Perspectives on Mental Illness: Development and Validation.

IMPORTANCE: Understanding the root cause of mental illness stigma is necessary to adopt effective management strategies. OBJECTIVE: To establish a stable and effective text-picture integration rating scale to predict public perspectives on mental illness and to examine its reliability and validity. DESIGN: Descriptive cross-sectional study using internet survey data. SETTING: Online. PARTICIPANTS: Two hundred volunteers. RESULTS: The 10-item the Text-Picture Integration Scale for Perspectives on Mental Illness was developed. The authors conducted data analysis using SPSS to evaluate the reliability and criterion-related validity of the Mental Health Literacy Scale (MHLS). The Text-Picture Integration Scale's item-level content validity index ranged from 0.83 to 1.00, and the scale-level content validity index was 0.97. The scale demonstrated acceptable reliability (Cronbach's α = .80). The mean value of individual items ranged from 3.18 to 4.48, and the mean total score was 39.44 (SD = 8.47). The Text-Picture Integration Scale exhibited satisfactory criterion-related validity with the MHLS (r = .76, p < .001). CONCLUSIONS AND RELEVANCE: Preliminary analyses support that the Text-Picture Integration Scale is a stable and effective rating scale to determine public perspectives on mental illness and is appropriate for evaluating destigmatization efforts. Plain-Language Summary: The study findings support the use of the Text-Picture Integration Scale as a stable and effective rating scale to determine public perspectives on mental illness. The scale is also appropriate for evaluating ways to address the stigmas that people associate with mental illness, which pose challenges for people in recovery. Occupational therapists can leverage their understanding of public perspectives on mental illness when choosing interventions to support the overall well-being of their clients with mental illness.

Constrictive bronchiolitis obliterans with a presumptive etiology of preceding feline herpesvirus infection in a cat.

BACKGROUND: Bronchiolar disorders are rarely recognized in cats. Constrictive bronchiolitis obliterans is characterized by concentric peribronchiolar fibrosis and inflammation of the bronchioles, but the underlying causes remain poorly understood in current small animal medicine. CASE PRESENTATION: A 9-year-old cat presented with paroxysmal tachypnea, infrequent cough and persistent labor breathing. Thoracic radiography showed lung hyperinflation and bronchointerstitial pattern, and pulmonary function assessment revealed flow limitation in the late-expiratory phase and poor response to short-acting bronchodilator. Dorsally distributed subpleural ground glass opacities with distinct margin and tree-in-bud opacities were observed on lung high-resolution computed tomography. The cat underwent bronchoalveolar lavage (BAL) and showed severe neutrophilic inflammation. Feline herpesvirus was the only pathogen detected in the BAL fluid. Multiple therapeutic attempts were unsuccessful and the cat died 8 weeks after the initial presentation. Necropsy revealed the infiltration of inflammatory cells, obstruction of the bronchiolar lumen, and submucosal concentric fibrosis suggesting constrictive bronchiolitis obliterans. Combining the pre- and post-mortem findings, as well as the time from symptom onset or BAL to necropsy, constrictive bronchiolitis obliterans was possibly triggered by a preceding feline herpesvirus infection in this case. CONCLUSIONS: The history of nonvaccinated status, lower airway neutrophilic inflammation, and presence of feline herpesvirus in the BAL fluid without coexistence of other pathogens led to the presumption that constrictive bronchiolitis obliterans was induced by a preceding feline herpesvirus infection in this cat. The pathological changes of bronchiolitis obliterans induced by a preceding feline herpesvirus infection could be different from that of cats with acute herpesvirus pneumonia, such as intranuclear inclusions would disappear over time and were no longer found 7-10 days after inoculation. The presence of patchy distribution of subpleural ground glass opacities on lung high-resolution computed tomography should raise the suspicion of peribronchiolar fibrosis. Clinical awareness of bronchiolar disorders as a differential diagnosis is important in cats with lung hyperinflation and labored breathing who show poor reversibility to bronchodilator.

Effect of Anterior Ankle-Foot Orthoses on Weight Shift in Persons With Stroke.

OBJECTIVE: To examine the effects of an anterior ankle-foot orthosis (AAFO) on the speed and accuracy of weight shift in persons with stroke. DESIGN: Cross sectional, repeated measures. SETTING: Neurologic rehabilitation department. PARTICIPANTS: People with stroke (N=24) who were unable to voluntarily dorsiflex the foot against gravity. INTERVENTION: The weight-shift performance was measured with and without the AAFO. MAIN OUTCOME MEASURES: The speed and accuracy of sustained and cyclic bilateral weight shift were measured using the computerized dynamic posturography. The movement velocity, maximum excursion, and directional control of sustained weight shift were calculated using the limits of stability test. The on-axis velocity gap, directional control, and stability of cyclic bilateral weight shift were calculated using the rhythmic weight shift test. RESULTS: For sustained weight shift, the maximum excursion of weight shift to the affected side was greater with the AAFO (P=.002). For cyclic bilateral weight shift, the on-axis velocity gap in the mediolateral (ML) direction was smaller at a fast speed (P=.004). The stability of the ML and anteroposterior weight shift was higher at slow (P=.002 and P<.001, respectively) and fast (P=.001 and P<.001, respectively) speeds when wearing the AAFO. CONCLUSIONS: The findings demonstrated that persons with stroke who wear an AAFO might improve the excursion of the sustained weight shift to the affected side and the speed and stability of cyclic bilateral weight shift in the ML direction.

Detection of Feline Coronavirus in Bronchoalveolar Lavage Fluid from Cats with Atypical Lower Airway and Lung Disease: Suspicion of Virus-Associated Pneumonia or Pneumonitis.

The premortem understanding of the role of feline coronavirus (FeCoV) in the lungs of cats is limited as viruses are seldom inspected in the bronchoalveolar lavage (BAL) specimens of small animal patients. This study retrospectively analyzed the prevalence of FeCoV in BAL samples from cats with atypical lower airway and lung disease, as well as the clinical characteristics, diagnostic findings, and follow-up information. Of 1162 clinical samples submitted for FeCoV RT-nPCR, 25 were BAL fluid. After excluding 1 case with chronic aspiration, FeCoV was found in 3/24 (13%) BAL specimens, with 2 having immunofluorescence staining confirming the presence of FeCoV within the cytoplasm of alveolar macrophages. The cats with FeCoV in BAL fluid more often had pulmonary nodular lesions (66% vs. 19%, p = 0.14) and multinucleated cells on cytology (100% vs. 48%, p = 0.22) compared to the cats without, but these differences did not reach statistical significance due to the small sample size. Three cats showed an initial positive response to the corticosteroid treatment based on the clinical signs and radiological findings, but the long-term prognosis varied. The clinical suspicion of FeCoV-associated pneumonia or pneumonitis was raised since no other pathogens were found after extensive investigations. Further studies are warranted to investigate the interaction between FeCoV and lung responses in cats.

Assessing breathing effort by barometric whole-body plethysmography and its relationship with prognosis in client-owned cats with respiratory distress.

BACKGROUND: Cats in respiratory distress have limited tolerance for manipulation, hindering clinical monitoring. Minute volume (MV) can be utilized to rate dyspnea in humans, but its relationship with respiratory distress in cats remains poorly investigated. HYPOTHESIS: Cats with respiratory distress will show higher MV per kg body weight (MV/BW) than normal cats, and the MV/BW increase will correlate with survival. ANIMALS: Fifty-two cats with respiratory distress from lung parenchymal disease, pleural space disease, lower airway obstruction (LAO), or upper airway obstruction were recruited since 2014. METHODS: This is a prospective observational study. Study cats were placed in a transparent chamber, allowing clinicians to easily observe their breathing status and record ventilation using barometric whole-body plethysmography (BWBP). Ventilatory variables of the 52 cats were compared with those of 14 historic control cats. Follow-up data, including disease category, clinical outcomes, and survival, were prospectively collected. RESULTS: Cats in respiratory distress demonstrated significantly higher MV/BW (397 mL/kg; range, 158-1240) than normal cats (269 mL/kg; range, 168-389; P < .001). Among the etiologies, cats with LAO, parenchymal, and pleural space disease exhibited higher-than-normal MV/BW trends. A cutoff value of 373 mL/kg (1.4-fold increase) indicated abnormally increased breathing efforts (sensitivity, 67%; specificity, 93%). MV/BW was independently associated with increased cardiorespiratory mortality in cats with respiratory distress (adjusted hazard ratio 1.17, 95% confidence interval [CI] 1.02-1.35; P = .03). CONCLUSIONS AND CLINICAL IMPORTANCE: Breathing efforts in cats can be noninvasively quantified using BWBP. Measurement of MV/BW could serve as a prognostic index for monitoring cats experiencing respiratory distress.

Antiviral activity of Vigna radiata extract against feline coronavirus in vitro.

Feline infectious peritonitis (FIP) is a fatal illness caused by a mutated feline coronavirus (FCoV). This disease is characterized by its complexity, resulting from systemic infection, antibody-dependent enhancement (ADE), and challenges in accessing effective therapeutics. Extract derived from Vigna radiata (L.) R. Wilczek (VRE) exhibits various pharmacological effects, including antiviral activity. This study aimed to investigate the antiviral potential of VRE against FCoV, addressing the urgent need to advance the treatment of FIP. We explored the anti-FCoV activity, antiviral mechanism, and combinational application of VRE by means of in vitro antiviral assays. Our findings reveal that VRE effectively inhibited the cytopathic effect induced by FCoV, reduced viral proliferation, and downregulated spike protein expression. Moreover, VRE blocked FCoV in the early and late infection stages and was effective under in vitro ADE infection. Notably, when combined with VRE, the polymerase inhibitor GS-441524 or protease inhibitor GC376 suppressed FCoV more effectively than monotherapy. In conclusion, this study characterizes the antiviral property of VRE against FCoV in vitro, and VRE possesses therapeutic potential for FCoV treatment.

Quantifiable features of a tidal breathing phenotype in dogs with severe bronchomalacia diagnosed by bronchoscopy.

Dynamic lower airway obstruction is the primary component of canine bronchomalacia, but the ventilatory function remains underinvestigated. This prospective study analyzed tidal breathing characteristics in 28 dogs, comprising 14 with severe bronchomalacia diagnosed by bronchoscopy versus 14 without respiratory disease. Spirometry was conducted in all dogs. Bronchoscopy with bronchoalveolar lavage or brush under anesthesia was performed in 14 dogs with cough and expiratory effort. Severe bronchomalacia was defined by the severity of collapse and total number of bronchi affected. Ventilatory characteristics were compared between groups. Results revealed that dogs with severe bronchomalacia had lower minute volume (218 vs 338 mL/kg, p = .039) and greater expiratory-to-inspiratory time ratio (1.55 vs 1.35, p = .01) compared to control dogs. The tidal breathing pattern of dogs with bronchomalacia was different from that of normal dogs, and the pattern differed from the concave or flat expiratory curves typical of lower airway obstruction. Compared to control dogs, dogs with severe bronchomalacia had a significantly prolonged low-flow expiratory phase (p < .001) on the flow-time plot and a more exponential shape of the expiratory curve (p < .001) on the volume-time plot. Flow-time index ExpLF/Te (>0.14) and volume-time index Vt-AUCexp (≤31%) had a high ROC-AUC (1.00, 95% confidence interval 0.88 to 1.00) in predicting severe bronchomalacia. In conclusion, the tidal breathing pattern identified here indicates abnormal and complicated ventilatory mechanics in dogs with severe bronchomalacia. The role of this pulmonary functional phenotype should be investigated for disease progression and therapeutic monitoring in canine bronchomalacia.

A small sample test of the factor structure of postural movement and bilateral motor integration using structural equation modeling.

The goal of this study was to examine the relationship between the validity of postural movement and bilateral motor integration in terms of sensory integration theory. Participants in this study were 61 Chinese children ages 48 to 70 months. Structural equation modeling was applied to assess the relation between measures tapping postural movement and bilateral motor integration: for postural movement, the measures involve the Monkey Task, Side-Sit Co-contraction, Prone on Elbows, Wheelbarrow Walk, Airplane, and Scooter Board Co-contraction from the DeGangi-Berk Test of Sensory Integration, and Standing Balance with Eyes Closed/Opened in Southern California Sensory Integration Tests. For bilateral motor integration, the measures chosen were the Rolling Pin Activity, Jump and Turn, Diadokokinesis, Drumming, and Upper Extremity Control from the DeGangi-Berk Test of Sensory Integration, and Cross the Midline in Southern California Sensory Integration Tests (SCSIT). Postural movement was highly correlated with the bilateral motor integration. The factor structure fit the theoretical conceptualization, classifying postural movement and bilateral motor integration together in the same category. Therapists could combine two separate objectives (postural movement and bilateral motor integration) of intervention in an activity to improve the adaptive skills based on the vestibular-proprioceptive integration.

Influence of concurrent lower respiratory tract disease on point-of-care lung ultrasound in small-breed dogs with myxomatous mitral valve disease.

BACKGROUND: Small-breed dogs commonly have concurrent myxomatous mitral valve disease (MMVD) and lower respiratory tract disease (LRTD). HYPOTHESIS: Small-breed dogs with preclinical MMVD and concurrent LRTD have more B-lines on point-of-care lung ultrasound (POC-LUS) compared to dogs without concurrent LRTD and are prone to misdiagnose as cardiogenic pulmonary edema (CPE). ANIMALS: A total of 114 small-breed dogs with preclinical MMVD. METHODS: A prospective study was conducted, in which POC-LUS was obtained and the number of B-lines was calculated by a single clinician using the Veterinary Bedside Lung Ultrasound Examination protocol. The presence/absence of LRTD was assessed by clinicians blinded to the POC-LUS results. RESULTS: Fifty and 64 dogs were in ACVIM stage B1 and B2, respectively. The presence of LRTD was prevalent in 74.6% (85/114) of small-breed dogs with preclinical MMVD. When a previously reported criterion for CPE diagnosis (≥2 sites with >3 B-lines/site) was applied, false-positive results were observed in 15.8% (18/114) of dogs with preclinical MMVD. The summated number of B-lines (3 vs. 1, P = .003), as well as the false-positive rate (20% vs 3%, P = .04), were significantly higher in dogs with LRTD compared with dogs without LRTD. Multivariable logistic regression showed the presence of abnormalities other than B-line on POC-LUS (eg, thickened pleura or consolidation) could predict false-positive results (odds ratio = 3.75, 95% confidence intervals 1.12-12.54; P = .03) after adjustment for other clinical and echocardiographic factors. CONCLUSIONS AND CLINICAL IMPORTANCE: Concurrent LRTD and abnormalities other than B-lines should be considered in the interpretation of POC-LUS in MMVD dogs.

Developing of Multidimensional Perspectives Checklist of Professionalism for Undergraduate Occupational Therapy Students in Assistive Technology Service: Delphi Study.

Professionalism is a critical attribute that occupational therapy students must establish throughout education, especially in the context of assistive technology (AT). This study aimed to construct a multidimensional perspectives checklist (MPC) from the stakeholders to reflect professionalism development in the AT service courses. Fifteen experts in AT clinical practice and educators (N = 15) consented to and completed three rounds of the Delphi survey. Data were qualitatively analyzed to form a preliminary checklist in the first round. In rounds two and three, participants rated their level of agreement with the MPC items. A descriptive analysis of consensus was performed. Thirty items were classified into five subscales (teachers, therapists, patients, peers, learners) and fit into a framework with three dimensions and seven categories. After the Delphi survey, the MPC achieved high consensus, convergence, and stability. Two additional categories of professionalism emerged in the study, namely aesthetic and personal characteristics and reflection. The MPC developed in this study reflects the perspectives of various stakeholders in occupational therapy practice, providing helpful information for students to prepare themselves. Therefore, the MPC could contribute to expanding and developing the scope of professionalism in occupational therapy, especially in AT service.

Ultrasonographic patterns, clinical findings, and prognostic variables in dogs from Asia with gallbladder mucocele.

BACKGROUND: Gallbladder mucocele (GBM) is a common biliary disorder in dogs that can be categorized into 6 types, but the value of this classification scheme remains unknown. Cholecystectomy is associated with high death rates and warrants additional interrogation. OBJECTIVES: Investigate the clinical value of ultrasonographic diagnosis of type of GBM and identify prognostic factors in dogs with GBM undergoing cholecystectomy. ANIMALS: Two hundred sixteen dogs. METHODS: Retrospective cohort study. Dogs with GBM diagnosed from 2014 to 2019 at 6 veterinary referral hospitals in Asia. Ultrasonogram images were reviewed and a GBM type (ie, types I-VI) assigned. RESULTS: Dogs with GBM type V as compared to I (OR, 8.6; 95% CI, 2.6-27.8; P < .001) and III (OR, 10.0; 95% CI, 2.5-40.8; P = .001), and dogs with type VI compared to I (OR, 10.5; 95% CI, 1.8-61.2; P = .009) and III (OR, 12.3; 95% CI, 1.8-83.9; P = .01) were more likely to exhibit signs of biliary tract disease. Independent predictors of death after cholecystectomy included age (OR, 2.81; 95% CI, 1.41-5.59; P = .003) and intraoperative systolic blood pressure (SBP) nadir. There was an interaction between SBP nadir and gallbladder rupture; SBP nadir in dogs with (OR, 0.92; 95% CI, 0.89-0.94; P < .001) and without (OR, 0.88; 95% CI, 0.82-0.93; P < .001) gallbladder rupture. CONCLUSION AND CLINICAL IMPORTANCE: Increasing developmental stage of GBM could be associated with an increased likelihood of biliary tract related clinical signs. Nadir SBP deserves further investigation as a prognostic or potentially modifiable variable, particularly in the presence of gallbladder rupture.

A psychometric evaluation of the Taiwan version of the Individual Workload Perception Scale.

AIM: The aim was to evaluate the psychometric properties of the Taiwan version of the Revised Individual Workload Perception Scale on staff nurses in southern Taiwan. BACKGROUND: Most psychometric measures of the nursing work environment were developed in North America and reflect nursing practice in Western health care environments. As these instruments are used most often in translation, it is important to inquire whether they appropriately capture the characteristics of nursing work in environments outside of the original contexts. DESIGN: A descriptive, cross-sectional study was conducted between 1 June-30 September 2009, with a convenience sample of 344 nurses providing direct patient care at a regional teaching hospital in southern Taiwan. The Taiwan version of the Revised Individual Workload Perception Scale was created by translating the original English language Individual Workload Perception Scale-Revised, which is used to measure the staff nurses' perceptions of their work environment. The Taiwan version of the Revised Individual Workload Perception Scale is a 24-item five-point Likert scale measuring manager support, peer support, unit support, workload and intent to stay. Content validity, construct validity and reliability of the Taiwan version of the Revised Individual Workload Perception Scale were evaluated. RESULTS: The content validity index of the Taiwan version of the Revised Individual Workload Perception Scale was 0.93. Cronbach's alpha for the total Taiwan version of the Revised Individual Workload Perception Scale was 0.88, with a range of 0.61-0.85 for the subscales. Factorial validity was supported using a five-factor model solution that accounted for 55.47% of the total variance for nursing work environment. Manager support had the highest explained variance (28.38%). CONCLUSIONS: Acceptable reliability and content validity were found; the Taiwan version of the Revised Individual Workload Perception Scale is recommended for measuring nurses' perceptions of their work environment. RELEVANCE TO CLINICAL PRACTICE: Psychometric properties of a scale such as the Individual Workload Perception Scale translate cross-culturally, with minor adjustments. The Taiwan version of the Revised Individual Workload Perception Scale can be used to provide data and analyses in comparisons with nursing work environment features internationally.

An observational study of the role of indoor air pollution in pets with naturally acquired bronchial/lung disease.

BACKGROUND: Indoor air pollution (IAP) is an emerging issue for both human and veterinary patients under the concept of 'One Health'. The association between IAP and respiratory disease in companion animals has been reported. OBJECTIVES: The present study investigated the relationship between quantifiable indoor air quality and clinical characteristics of naturally acquired bronchial/lung disease in pet dogs and cats. METHODS: A total of 36 clinical cases (20 dogs and 16 cats) with naturally acquired bronchial/lung disease were prospectively recruited. Lower airway samples were collected and analysed, and clinical signs and the information from pulmonary function testing were examined. Indoor air quality was estimated by the average concentration of particles measuring ≤2.5 µm (PM2.5, µg/m3 ) and volatile organic compounds (VOC, ppm) in the animals' domestic microenvironments. RESULTS: Exposure to IAP was not found to be correlated with the severity of clinical signs, pulmonary function changes or bronchoalveolar lavage fluid cytology in cats with bronchial/lung disease. However, a hypercellular response in canine lower airways was found to be associated with poor indoor air quality, including unacceptable indoor PM2.5 levels (>35 µg/m3 ) or increases in VOC concentration (>1 ppm) in places most commonly frequented by the dogs in the home. CONCLUSIONS: Poor indoor air quality may exacerbate airway disease in pets and should not be ignored in modern society.

Usefulness of Chest Ultrasonography in Predicting Diagnosis in Non-emergency Small Animal Patients With Lung Parenchymal and Pleural Disease.

Chest ultrasonography has become an indispensable tool for pulmonary specialists in human medicine, but its current use in dogs and cats is primarily for emergency. The diagnostic performances of various ultrasonographic features other than comet-tail artifacts are of limited information in veterinary literatures. Therefore, the aims of this retrospective study were to investigate ultrasonographic findings in feline and canine respiratory patients with lung parenchymal and pleural space diseases, and to assess how ultrasonographic features correspond to specific diagnoses. Sixty-five non-emergency cases with radiographically identified lung parenchymal and pleural space abnormalities were included. Medical records and ultrasound video clips were reviewed, and additional follow-up information was subsequently collected. Common findings such as comet-tail artifacts (87.7% of cases), consolidation (84.6%), and thickened/irregular pleura (69.2%) were not distinguishable for a specific diagnosis. The presence of nodular/mass-like lesion (OR = 212, p < 0.001) and consolidated lesion with heteroechogenicity (OR = 240, p < 0.001) was significantly associated with and strongly predictive of neoplasia after age, body weight and other sonographic findings were adjusted. The finding of nodular/mass-like lesion has the best diagnostic performance (AUC = 0.93) for neoplasia, with sensitivity of 91.7% and specificity of 93.6%. For predicting a diagnosis of pneumonia, although several sonographic features were found to be statistically associated with pneumonia, only a negative finding of nodular/mass-like lesion showed good diagnostic performance (AUC = 0.83, sensitivity 95.7%, specificity 71%). These findings demonstrate the value of chest ultrasonography in predicting diagnosis in non-emergency cases. The application of thoracic ultrasound in small animal respiratory patients as part of non-invasive assessment warrants further investigation.

Characterization of antimicrobial resistance patterns and integrons in human fecal Escherichia coli in Taiwan.

Two hundred and twenty-five fecal strains of Escherichia coli isolated from 109 non-hospitalized adults in 2006 were investigated for susceptibility to antibiotics and for the presence of integrons. High resistance rates in fecal strains of E. coli were observed for streptomycin (52.0%), ampicillin (50.2%), piperacillin (50.2%), trimethoprim/sulfamethoxazole (47.6%) and chloramphenicol (33.8%). Integrons were found in 31.5% (71/225) of the strains using an integrase gene PCR assay. Among 71 integrase-positive strains, 65 strains belonged to class 1 integrons, while the remainder belonged to class 2. Gene cassette patterns of class 1 integrons were further characterized by PCR and direct sequencing. Among those class 1 integrase-containing isolates, the integron cassette region was amplified by PCR in 40.0% (26 of 65) of isolates. Five different antimicrobial resistance gene cassette arrays were found in those isolates. These gene cassettes included those encoding resistance to trimethoprim (dfrV, dfrA7, dfrA12, dfrA17) and streptomycin (aadA1, aadA2, aadA5). Among those gene cassette arrays, dfrA12-orfF-aadA2 was found in 53.8% (14/26) of the isolates. These findings indicate that multidrug resistance of fecal flora is common in Taiwan and that integrons play an important role in resistance to trimethoprim and streptomycin in humans.

Association between indoor air pollution and respiratory disease in companion dogs and cats.

BACKGROUND: Indoor air pollution (IAP) leads to important respiratory morbidity and mortality in humans. Companion dogs and cats share the same household environment with their owners and are exposed to IAP. HYPOTHESIS: Pets with respiratory disease are more commonly exposed to indoor air pollutants in their homes and to worse air quality than pets without respiratory disease. ANIMALS: Three hundred and forty-eight animals (230 dogs and 118 cats) were recruited. METHODS: Dogs and cats attending the National Taiwan University Veterinary Hospital were prospectively enrolled over a 12-month period. Questionnaires were collected from pet owners regarding the status of signs of respiratory problem of animals and air pollutants in their homes. Clinical assessment was performed by veterinarians on all animals included in the case-control study and the presence/absence of respiratory disease and diagnoses were recorded. Individual exposure to particulate matter of 2.5 µm or less (PM2.5) was estimated in the domestic microenvironment of the animals. RESULTS: Dogs with respiratory disease were more commonly exposed to incense burning than control dogs (30 versus 13%, P = .045), but household PM2.5 level was not different between dogs with and without respiratory disease [median 30.8 µg/m3 , range 10.8-214.2 versus median 38.2 µg/m3 , range 5.4-69.4, P = .57]. Signalment factors (age, body weight, and body condition score) instead of IAP factors were associated with respiratory disease in dogs using multivariable logistic regression. In contrast, household PM2.5 level was significantly higher in cats with respiratory disease than in control cats [median 38.6 µg/m3 , range 17.8-131.2 versus median 27.4 µg/m3 , range 15.4-70.0, P = .017]. Cats living in households with PM2.5 > 35 µg/m3 were more likely to have respiratory disease than those living in households with acceptable levels of PM2.5 (OR = 4.13, 95% CI 1.12-15.27, P = .03). CONCLUSIONS AND CLINICAL IMPORTANCE: The link between IAP and respiratory disease in dogs is complicated. An unacceptable level of household PM2.5 (>35 µg/m3 ) is significantly associated with respiratory disease in cats. The effect of IAP on the respiratory health of companion animals warrants further attention.

Dirofilaria immitis exposure status in client-owned cats with or without lower airway/lung-associated signs: case-control study in a canine heartworm-endemic area.

Objectives Heartworm-associated respiratory disease (HARD) is a recently recognised pathological manifestation in cats caused by Dirofilaria immitis exposure. This study aimed to estimate the percentage of cats at risk of developing HARD in a heartworm-endemic area (Taipei, Taiwan), and to test the correlation of heartworm exposure and the presence of lower airway/lung clinical signs (LA/L signs). Methods This was a prospective case-control study. The study design called for the enrolment of at least 80 cats with LA/L signs and at least 80 cats without such clinical signs in a 1 year period. The D immitis antibody seroprevalence of the two cohorts was compared. Results From February 2014 to January 2015, 187 client-owned cats were prospectively enrolled: 83 clinical cases with LA/L signs and 104 cats without such signs. Antibody seropositivity was approximately twice as frequent in cats with LA/L signs (13.3%) than in cats without signs (7.8%) (odds ratio [OR] 1.814); nevertheless, no statistically significant difference between the two cohorts ( P = 0.22) was found. We used 41 frozen samples from free-roaming cats to examine the possibility of different exposure rates to mosquito bites between client-owned cats and stray cats, finding the seroprevalence to be 7.5% in free-roaming cats - a result not statistically different to that in client-owned cats ( P = 0.60). Outdoor access was a significant risk factor for heartworm exposure in client-owned cats (OR 3.748; P = 0.03); however, living entirely indoors did not provide complete protection from exposure/infection. Conclusions and relevance Our results did not show statistically significant differences in antibody seroprevalence between cats with and without LA/L signs. LA/L signs were not always present under conditions of natural exposure. However, exposure to D immitis is not rare among client-owned cats, suggesting that heartworm prophylactics should be a part of routine care in all cats living in areas endemic for canine heartworm.

Systolic blood pressure of clinically normal and conscious cats determined by an indirect Doppler method in a clinical setting.

The purposes of the present study were to determine the systolic blood pressure (SBP) of clinically normal and conscious cats, and to set up reference values of feline SBP for subsequent clinical application. SBPs were measured in 53 healthy cats using an ultrasonic Doppler device. The mean SBP was 133.6 +/- 16.0 mmHg (range, 110.0-180.0 mmHg). The distribution of SBP values was not significantly affected by factors such as breed, body condition score, or age (P>0.05), but SBP values of female cats were significantly lower and more variable than those of males (t test, P=0.004; F test, P<0.001). Feline SBP between 114.3 mmHg and 149.5 mmHg was considered indicative of normotension. SBP values higher than 159.3 mmHg were defined as hypertension, and those less than 104.5 mmHg were determined as hypotension.

Simultaneous visual inspection for barometric whole-body plethysmography waveforms during pulmonary function testing in client-owned cats.

OBJECTIVES: For the purpose of applying a barometric whole-body plethysmography (BWBP) device as a routine clinical tool in client-owned cats, the objective of this study was to evaluate the methodological importance of simultaneous visual inspection (SVI) of graphic tracing. METHODS: To investigate the effect of SVI on the results obtained, 50 client-owned cats were included. Breath-by-breath analysis was conducted with BWBP software, and a commonly used rejection setting was chosen for automatic elimination (AE) of non-breath artefactual waveforms, according to tidal volume (TV), inspiratory and expiratory time, and the difference between inspiratory and expiratory volumes. During 10 mins of data recording, SVI for BWBP waveforms was performed to record manually time periods that were free of any artefacts. The two datasets derived from AE alone (AEA method) and AE plus SVI (SVI-AE method) were compared. The inter-observer effect on the process of SVI was evaluated on six cats. RESULTS: There were statistically significant differences (P <0.001) between the AEA and SVI-AE datasets for most BWBP parameters. Bland-Altman analysis of the parameter-enhanced pause (Penh) showed heterogeneous variances, indicating less agreement when the Penh values were large. Intra-individual coefficients of variation of Penh were significantly higher with the AEA method than with the SVI-AE method (61.1% vs 34.7%, respectively; P <0.001). Inter-observer agreement on the SVI process was excellent, and no statistically significant differences between the two observers were found for any BWBP parameters obtained by the SVI-AE method (P >0.05). CONCLUSIONS AND RELEVANCE: Visual inspection for BWBP waveforms in real time can reliably identify stable breathing signals in client-owned cats. The obtained results were significantly different when the SVI method was used in addition to AE. In the interpretation of BWBP parameters or comparison of measurements among studies, whether an SVI methodology was applied should be considered.

Use of and Self-Perceived Need for Assistive Devices in Individuals with Disabilities in Taiwan.

Assistive devices (ADs) can help individuals with disabilities achieve greater independence, and it can enhance the quality of their lives. This study investigated the use of and self-perceived need for ADs in individuals with disabilities, and determined the influence of gender, age as well as type and degree of disability on the use of and self-perceived need for ADs. This descriptive study utilized a cross-sectional survey design with a convenience sample of participants. A total of 1018 subjects with disabilities who visited an exhibition of assistive technology and two ADs research and development centers completed a questionnaires either by themselves or via a caregiver who completed the questionnaire on behalf of the subject or via interviewers trained specifically for this study. The Mann-Whitney U test and Kruskal-Wallis test were used to determine the influence of participant characteristics on the use of ADs. The results showed that 77.2% and 83.3% of the participants reported that they used and needed AD(s) to engage in activities of daily living. The mean quantity of the use of and self-perceived need for total types of ADs were 3.0 and 5.3, respectively. Participants with different disabilities reported different percentages of the use of various types of ADs. No difference was found between genders and among the age groups in the use of quantity of ADs. Individuals with different types and degrees of disability used different quantities of ADs. Participants with physical, visual and multiple disabilities used significantly more ADs compared to participants with intellectual disability. The total quantity of ADs used increased significantly with increased severity of disability. The mean use of assistive devices was lower compared to the mean need of individuals with disabilities. Further study is required to determine why patients feel the need for but not currently use a specific assistive device.
