Published: August 2022

Clinical importance: Feline infectious peritonitis (FIP) is one of the most important infectious diseases and causes of death in cats; young cats less than 2 years of age are especially vulnerable. FIP is caused by a feline coronavirus (FCoV). It has been estimated that around 0.3% to 1.4% of feline deaths at veterinary institutions are caused by FIP. Scope: This document has been developed by a Task Force of experts in feline clinical medicine as the 2022 AAFP/EveryCat Feline Infectious Peritonitis Diagnosis Guidelines to provide veterinarians with essential information to aid their ability to recognize cats presenting with FIP. Testing and interpretation: Nearly every small animal veterinary practitioner will see cases. FIP can be challenging to diagnose owing to the lack of pathognomonic clinical signs or laboratory changes, especially when no effusion is present. A good understanding of each diagnostic test’s sensitivity, specificity, predictive value, likelihood ratio and diagnostic accuracy is important when building a case for FIP. Before proceeding with any diagnostic test or commercial laboratory profile, the clinician should be able to answer the questions of ‘why this test?’ and ‘what do the results mean?’ Ultimately, the approach to diagnosing FIP must be tailored to the specific presentation of the individual cat. Relevance: Given that the disease is fatal when untreated, the ability to obtain a correct diagnosis is critical. The clinician must consider the individual patient’s history, signalment and comprehensive physical examination findings when selecting diagnostic tests and sample types in order to build the index of suspicion ‘brick by brick’. Research has demonstrated efficacy of new antivirals in FIP treatment, but these products are not legally available in many countries at this time. The Task Force encourages veterinarians to review the literature and stay informed on clinical trials and new drug approvals.

Published: August 2022

Objective Social media use has grown over time. However, it is unclear how people with a self-reported history of cardiovascular disease or cardiovascular disease-related risk factors such as diabetes and hypertension use social media. Methods Data from the 2020 Health Information National Trends Survey (HINTS 5, Cycle 4) were analyzed (N = 3865). Only respondents with complete data for all variables of interest were included in the analyses, resulting in 306 respondents with a heart condition, 1291 with hypertension, and 608 with diabetes. We explored associations between two dependent variables: (1) participated in an online forum or support group and (2) watched a health-related video on YouTube, and sociodemographic factors and patient-provider communication. Analyses were conducted separately by medical condition. Odds ratios, 95% confidence intervals, and p-values were calculated. Results In respondents with a heart condition, hypertension, or diabetes, 5.4%, 8.4%, and 10.3% had participated in an online support group and 29.6%, 40.4%, and 36.6% had watched health-related videos on YouTube, respectively. Univariately, the odds of using online support groups was associated with younger age (vs. > = 65) in people with a heart condition and hypertension, but not diabetes. Regarding YouTube, younger age was associated with watching health-related videos across all three medical conditions, with additional gender and education associations observed in those with hypertension. There were no associations between social media use and patient-provider communication. Conclusions These findings may inform the selection of social media platforms for behavioral interventions depending on the intended patient population and goals (e.g. social support vs. video-based health education).

Purpose: To compare the incidence and visual outcomes of endophthalmitis after injection of an intravitreal dexamethasone implant and injection of intravitreal ranibizumab. Methods: This retrospective cohort study assessed endophthalmitis in eyes receiving an intravitreal injection of a 0.7 mg dexamethasone implant (DEX group), 0.5 mg ranibizumab (R5 group), or 0.3 mg ranibizumab (R3 group) between January 1, 2016, and May 31, 2018, at 2 large retina practices in the United States. Results: Suspected endophthalmitis occurred in 5 eyes after 4973 DEX injections, 43 eyes after 163 974 R5 injections, and 6 eyes after 18 954 R3 injections. Suspected endophthalmitis was significantly more common in the DEX group (1/995) than in the R5 group (1/3813) ( P = .008) but not than in the R3 group (1/3159) ( P = .10). Visual acuity outcomes were similar in the 3 groups. Conclusions: Suspected endophthalmitis might be more common after 0.7 mg dexamethasone injections than after 0.5 mg ranibizumab injections. Culture-positive endophthalmitis rates were similar across all 3 medications.

Objective: This study assessed the use of Aloe vera lotion as an alternative coupling medium for ultrasound imaging. Materials and Methods: A prospective analytical research design was adopted. A total of 50 subjects who consented were randomly recruited into the study from the University of Calabar Teaching Hospital (UCTH), Calabar and the Gijuwie Medical Diagnostics, Calabar. A total of 50 image pairs were obtained on scanning with Aloe vera lotion (Image A) and commercial ultrasound gel (Image B) for comparison. Image quality was assessed using anatomical details (AD) and visualization of hyperechoic structures (VHS) as criteria. Results: A substantial agreement was seen among raters (A: k = 0.658, B = 0.691; P < .05) with acceptable level of consistency (Cronbach’s alpha scores of 0.701 and 0.825 for Aloe vera lotion and commercial gel, respectively) based on AD. Images recommended as acceptable by raters was 91.7% for Aloe vera lotion and 81.7% for commercial gel. Both methods demonstrated almost perfect agreement (kappa > 80; P < .05) with each other based on AD and VHS (Table 3). Conclusion: Aloe vera lotion, which is locally available and relatively affordable, has the potential to be used as acoustic coupling medium in diagnostic sonography.

Published: August 2022

Abstract
Background
More than 2/3 of children and adolescents in Germany regularly suffer from headaches. Headache-related limitations in everyday life, school drop-out and educational impairment are common. Structured therapy programs for young headache patients are widely missing.

Methods
One hundred eleven patients with frequent migraine and/or tension type headache were treated in a 15 hour group program in afternoons, parallel with school, parents received 7 hours of therapy. At the beginning of the program (T0), 6 (T1) and 12 months (T2) after completion, data on headache related disability (PedMidas), headache frequency, intensity, and pediatric pain disability score (PPDI) were prospectively collected to investigate the effects of the therapy.

Results
Seventy-five patients (9-19 years, median = 14; 66.7% female) and their parents provided patient reported outcome measures showing at T1 (65 patients) and T2 (47 patients) reduced headache frequency (last 3 months headache days median T0: 30 days; T1: 18 days, reduction of median 12 days since T0; T2: 13 days, reduction of median 17 days since T0). Linear mixed models revealed significant reduction (T0/T1 p = 0,002; T0/T2 p = 0,001). Reduced headache disability has been reported at T1 and T2 (PedMidas median T0 = 30, T1 = 15, T2 = 7; p < 0,001, p < 0,001 respectively). Follow up data of a subgroup of patients 24 months after the treatment point to sustainable effects.

Conclusions
The interdisciplinary multimodal headache therapy program DreKiP reduces headache frequency and headache related disability significantly 6-12 months following its completion.

Cervical cord reperfusion injury: a rare complication of spine surgery
Authors: Hasan Wafa , Khan Khalid , Alomani Najla 
Published: August 2022

Abstract
Background
Anterior cervical discectomy and fusion procedure has been considered the surgical procedure of choice for the management of degenerative cervical myelopathy. Postoperative paresis is one of the most serious and concerning complications. The occurrence of such complications without any clear anatomic explanation (e.g., epidural hematoma) is unusual.

Case presentation
A 62-year-old man underwent cervical spine decompression via the anterior approach for marked central canal stenosis and spinal cord compression due to degenerative changes. The operation was performed under neuromonitoring, and a complete discectomy for the levels C3/C4, C5/C6, and C6/C7 was performed. Fluoroscopy confirmed the correct placement of the inserted plates and screws. No motor or sensory deficits were evident after postoperative recovery. However, 1 day later, the patient experienced progressive weakness in his both upper and lower extremities. A whole spine MRI study was performed to exclude epidural hematoma as the possible etiology. Although no localized fluid collection or hematoma was observed, the study demonstrated abnormal signal intensity in the spinal cord on T2-weighted images at the levels C5 to C7. Such findings were consistent with changes in cord reperfusion syndrome. The patient was administered intravenous methylprednisolone therapy. Gradual improvement in the muscle power in his both extremities was noted, and the patient was discharged with a satisfactory outcome. One month later, the MRI study was repeated and showed regression of the previously seen high T2 signal intensity in the cervical spine.

Conclusion
Cervical cord reperfusion injury is an extremely rare etiology of neurological deterioration following spinal cord decompressive surgeries. Clinicians need to maintain a high index of suspicion for this complication and should be familiar with its imaging appearance.

Published: August 2022

Abstract
Background
To assess baseline characteristics, drug utilisation and healthcare use for oral anticoagulants (OACs) following the introduction of non-vitamin K antagonist oral anticoagulants among patients with atrial fibrillation in primary care in Norway.

Methods
In this retrospective longitudinal cohort study, 92,936 patients with atrial fibrillation were identified from the Norwegian Primary Care Registry between 2010 and 2018. Linking to the Norwegian Prescription Database, we identified 64,112 patients (69.0%) treated with OACs and 28,824 (31%) who were untreated. Participants were followed until 15 May 2019, death, or loss to follow-up, whichever came first. For each OAC, predictors of initiation were assessed by modelling the probability of initiating the OAC using logistic regression, and predictors of the first switch after index date were assessed using multivariable Cox proportional hazards models. The numbers of primary care visits per quarter by index OAC were plotted and analysed with negative binomial regression analyses offset for the log of days at risk.

Results
Patients treated with OACs were older, had more comorbidities, and higher CHA2DS2-VASc scores than untreated patients. However, the mean CHA2DS2-VASc in the non-OAC group was 1.58 for men and 3.13 for women, suggesting an indication for OAC therapy. The percentage of patients with atrial fibrillation initiating OACs increased from 59% in 2010 to 79% in 2018. Non-vitamin K antagonist oral anticoagulant use increased throughout the study period to 95% of new OAC-treated patients in 2018, and switches from warfarin to non-vitamin K antagonist oral anticoagulants were common. The persistence of OAC treatment was > 60% after four years, with greatest persistence for apixaban. Patients treated with non-vitamin K antagonist oral anticoagulants had fewer primary care visits compared with those treated with warfarin (incidence rate ratio: 0.73, 95% confidence interval 0.71 to 0.75).

Conclusion
In this Norwegian primary care study, we found that the shift from warfarin to non-vitamin K antagonist oral anticoagulants was successful with 95% use in patients initiating OACs in 2018, and associated with fewer general practitioner visits. Persistence with OACs was high, particularly for apixaban. However, many patients eligible for treatment with OACs remained untreated.
Agreement between standard and self-reported assessments of physical frailty syndrome and its components in a registry of community-dwelling older adults
Authors: Buta Brian , Zheng Scott , Langdon Jackie , Adeosun Bukola , Bandeen-Roche Karen , Walston Jeremy , Xue Qian-Li 
Published: August 2022

Abstract
Background
The ability to identify frail older adults using a self-reported version of the physical frailty phenotype (PFP) that has been validated with the standard PFP could facilitate physical frailty detection in clinical settings.

Methods
We collected data from volunteers (N = 182), ages 65 years and older, in an aging research registry in Baltimore, Maryland. Measurements included: standard PFP (walking speed, grip strength, weight loss, activity, exhaustion); and self-reported questions about walking and handgrip strength. We compared objectively-measured gait speed and grip strength to self-reported questions using Cohen’s Kappa and diagnostic accuracy tests. We used these measures to compare the standard PFP with self-reported versions of the PFP, focusing on a dichotomized identification of frail versus pre- or non-frail participants.

Results
Self-reported slowness had fair-to-moderate agreement (Kappa(k) = 0.34–0.56) with measured slowness; self-reported and objective weakness had slight-to-borderline-fair agreement (k = 0.10–0.21). Combining three self-reported slowness questions had highest sensitivity (81%) and negative predictive value (NPV; 91%). For weakness, three questions combined had highest sensitivity (72%), while all combinations had comparable NPV. Follow-up questions on level of difficulty led to minimal changes in agreement and decreased sensitivity. Substituting subjective for objective measures in our PFP model dichotomized by frail versus non/pre-frail, we found substantial (k = 0.76–0.78) agreement between standard and self-reported PFPs. We found highest sensitivity (86.4%) and NPV (98.7%) when comparing the dichotomized standard PFP to a self-reported version combining all slowness and weakness questions. Substitutions in a three-level model (frail, vs pre-frail, vs. non-frail) resulted in fair-to-moderate agreement (k = 0.33–0.50) with the standard PFP.

Conclusions
Our results show potential utility as well as challenges of using certain self-reported questions in a modified frailty phenotype. A self-reported PFP with high agreement to the standard phenotype could be a valuable frailty screening assessment in clinical settings.

Abstract
Background
Tuberculosis (TB) had been the leading lethal infectious disease worldwide for a long time (2014–2019) until the COVID-19 global pandemic, and it is still one of the top 10 death causes worldwide. One important reason why there are so many TB patients and death cases in the world is because of the difficulties in precise diagnosis of TB using common detection methods, especially for some smear-negative pulmonary tuberculosis (SNPT) cases. The rapid development of metabolome and machine learning offers a great opportunity for precision diagnosis of TB. However, the metabolite biomarkers for the precision diagnosis of smear-positive and smear-negative pulmonary tuberculosis (SPPT/SNPT) remain to be uncovered. In this study, we combined metabolomics and clinical indicators with machine learning to screen out newly diagnostic biomarkers for the precise identification of SPPT and SNPT patients.

Methods
Untargeted plasma metabolomic profiling was performed for 27 SPPT patients, 37 SNPT patients and controls. The orthogonal partial least squares-discriminant analysis (OPLS-DA) was then conducted to screen differential metabolites among the three groups. Metabolite enriched pathways, random forest (RF), support vector machines (SVM) and multilayer perceptron neural network (MLP) were performed using Metaboanalyst 5.0, “caret” R package, “e1071” R package and “Tensorflow” Python package, respectively.

Results
Metabolomic analysis revealed significant enrichment of fatty acid and amino acid metabolites in the plasma of SPPT and SNPT patients, where SPPT samples showed a more serious dysfunction in fatty acid and amino acid metabolisms. Further RF analysis revealed four optimized diagnostic biomarker combinations including ten features (two lipid/lipid-like molecules and seven organic acids/derivatives, and one clinical indicator) for the identification of SPPT, SNPT patients and controls with high accuracy (83–93%), which were further verified by SVM and MLP. Among them, MLP displayed the best classification performance on simultaneously precise identification of the three groups (94.74%), suggesting the advantage of MLP over RF/SVM to some extent.

Conclusions
Our findings reveal plasma metabolomic characteristics of SPPT and SNPT patients, provide some novel promising diagnostic markers for precision diagnosis of various types of TB, and show the potential of machine learning in screening out biomarkers from big data.
Examining the impact of excessive daytime sleepiness on utility scores in patients with obstructive sleep apnoea and/or narcolepsy in five European countries

Published: August 2022

Abstract
Background
Excessive daytime sleepiness (EDS) is a cardinal symptom of narcolepsy and affects many patients with obstructive sleep apnoea (OSA). EDS is associated with reduced quality of life, increased accident risk, and poor workplace performance. Given the impact of EDS, the ability to predict health-related utility from sleepiness is valuable for examining the cost effectiveness of novel treatments. The aim of this study was to examine the association between EDS and EQ-5D in patients with OSA and/or narcolepsy by modelling EQ-5D utility scores from Epworth Sleepiness Scale (ESS) scores.

Methods
Data were obtained from the Europe 2016/2017 National Health and Wellness Survey, an online, general population survey, designed to represent the age and gender composition of each country’s adult population. Analyses included 2,348 patients self-reporting symptomatic and diagnosed OSA (n = 2,277), narcolepsy (n = 48), or both (n = 23). Multivariable models were used to examine ESS as a predictor of EQ-5D utility while adjusting for covariates of interest. Results were validated following the National Institute for Health and Care Excellence Decision Support Unit guidelines for predictive modelling.

Results
Utility decreased as EDS severity increased (no EDS: 0.711 ± 0.251, mild: 0.685 ± 0.261, moderate: 0.643 ± 0.268, severe: 0.559 ± 0.323). Whereas participants with only OSA or only narcolepsy did not differ in utility, those with both conditions had lower scores (0.685 ± 0.266 and 0.627 ± 0.325 vs. 0.439 ± 0.340, respectively). Piecewise linear regression identified a single breakpoint at ESS score of 11.29. In the final model, for each point increase in ESS score, the corresponding decrease in EQ-5D utility was larger among patients with ESS scores ≥ 12 compared to patients with ESS scores ≤ 11 (model slopes: -0.0131 vs. -0.0026, respectively). Findings from the validation sample confirmed these results.

Conclusions
This study demonstrates the impact of sleepiness on quality of life (QoL) and its negative impact irrespective of sleep condition (OSA or narcolepsy). The breakpoint identified is relatively consistent with the established ESS cutoff score ≥ 11, which demarcates pathological sleepiness. Furthermore, as EDS severity worsens (increases) on the ESS, the impact on QoL is greater.

Abstract
Background and aims
Platelets play an important role in homeostasis however, they have also been associated with increased mortality after myocardial infarction. In the present study, we investigated whether platelet count is associated with differences in the short-term prognosis at the time of hospital discharge and early neurological deterioration in ischemic stroke patients.

Methods
Patients with ischemic stroke were enrolled from among 661 cerebrovascular disease patients admitted between January 2018 and December 2020. Patients who received hyperacute treatment, had a pre-onset modified Rankin scale (mRS) ≥ 3, transient ischemic attack, or active malignant disease were excluded. The platelet count was divided into quartiles (Q1-4) according to the number of patients, and the relationship between platelet count and prognosis was assessed using multivariable analysis.

Results
In total, 385 patients were included in the study. Regarding the functional outcome by platelet count, there was a significant increase in mRS ≥ 3 at discharge in the Q4 (range: 243–1327 × 109/L, p = 0.013, ORs: 1.674, 95%CI: 1.253–6.681) group compared to the Q3 (range: 205–242 × 109/L) group even after adjusting for factors with P < 0.2 in univariate analysis. Furthermore, the frequency of neurological deterioration (NIHSS ≥ 4) within 1 week was significantly lower in the Q3 group than in the Q1 (range; 19–173 × 109/L) and Q4 groups even after adjustment (Q1; p = 0.020 ORs: 6.634, 95%CI: 1.352–32.557, Q4; p = 0.007 ORs: 8.765, 95%CI: 1.827–42.035).

Conclusion
Platelet count at onset may affect the prognosis of cerebral infarction and early neurological deterioration. This study may help clarify the pathogenesis of cerebral infarction to improve prognosis.
