The incidence and trends of proteinuria, azotemia and hypertension in cats receiving toceranib phosphate.

OBJECTIVES: This retrospective study aimed to determine the incidence and trends of proteinuria, elevations in serum creatinine and urea, and systolic blood pressure in cats undergoing treatment with toceranib. METHODS: In total, 32 cats treated with toceranib for malignancies were analyzed. Cats were included if urinalysis and urine protein:creatinine ratio (UPC) measurements were available at 28 days (T1) and 56 days (T2) after starting the treatment. Cats with concurrent lower urinary tract disease, including urinary tract malignancy, were excluded. Friedman's ANOVA compared variables between time points, and the Spearman test assessed the correlation between treatment duration and UPC. RESULTS: The median starting dose of toceranib was 2.68 mg/kg (range 1.7-3.9). In total, 15 (46.9%) cats received concurrent non-steroidal anti-inflammatory drugs. The most commonly treated tumors were oral squamous cell carcinoma (n = 10) and mast cell tumor (n = 5). None of the 32 cats developed progressive proteinuria or azotemia during the follow-up period (median 56 days; range 56-336). Notably, UPC and serum creatinine were significantly lower at T2 compared with baseline (P = 0.012 and 0.001, respectively). Among the four cats with baseline proteinuria, UPC decreased over time with or without concurrent telmisartan treatment (n = 2). All four of these cats experienced a reduction in tumor size with toceranib concurrently with their decreased UPC. There was no significant correlation between UPC and the duration of toceranib treatment (P = 0.089). Blood pressure was not significantly different over the assessed time points. CONCLUSIONS AND RELEVANCE: The incidence of proteinuria, renal azotemia and hypertension in cats treated with toceranib for neoplasia appears to be low. Toceranib may be a viable treatment option even in cats with pre-existing proteinuria or renal disease, with careful monitoring of trends recommended.

Evaluation of the Safety and Effectiveness of Oral Minoxidil in Children: A Systematic Review.

The minimal adverse-effect profile and positive clinical response of low-dose oral minoxidil (LDOM) have recently caused the drug to gain popularity for the treatment of hair disorders in adults. However, in the pediatric population, hesitancy still surrounds the use of oral minoxidil given the wide profile of potential side effects the drug offers. This review aims to characterize the safety and use of oral minoxidil in children for the treatment of all disorders to equip physicians with ample knowledge when prescribing oral minoxidil in the pediatric population. A total of 41 studies (19 case reports, 10 cohort studies, 7 retrospective chart reviews, and 5 case series) that reported data on 442 pediatric patients for whom oral minoxidil was used for treatment were included. Conditions for which treatment with minoxidil was described were hair disorders (83.9%, 371/442) and hypertension (11.3%, 50/442); accidental usage (4.8%, 21/442) was also noted in the literature and included in this review. This review is broken down by dosage and describes the safety and efficacy of oral minoxidil in pediatric patients aged 0 to 18 years old for the treatment of hair disorders. This review found that LDOM may represent a safe option for the treatment of hair disorders in children. This study also suggests moderate and high doses of oral minoxidil may not be safe for use in children. Additional studies are needed to further understand this drug's efficacy and safety in children.

Cooperative interactions between neurotrophin receptors and CXCR4 regulate macrophage phenotype and susceptibility to activation by HIV.

Neural damage due to inflammatory activation of macrophages and microglia is a consequence of HIV infection that leads to cognitive dysfunction. The damage is due, in part, to the release of factors that impair neuronal function but the mechanisms that control their release are poorly understood. Previous studies have shown that mature nerve growth factor (NGF) binding to tropomyosin receptor kinase A (TrkA), and proNGF acting through the p75 neurotrophin receptor (p75NTR) differentially control the phenotype of macrophages in response to HIV. However, the mechanisms responsible for these actions are unclear. The current studies demonstrated that in human monocyte-derived macrophages, CCR5 tropic HIV virions interact with the CXCR4 receptor to promote a neurotoxic macrophage phenotype. TrkA cooperatively interacted with CXCR4 to promote quick and dynamic changes in CXCR4 phosphorylation and more stable downstream actin remodeling in the form of membrane ruffles. TrkA signaling also promoted increased moacrophage calcium spiking, and low neurotoxic activity. Disruption of these interactions by HIV led to an alternative podosome-bearing phenotype with minimal calcium signaling and enhanced toxicity. Neurotrophin receptors provide an independent yet cooperative pathway for modifying the actin cytoskeleton in response to chemokines and subsequent degenerative activity. The strong opposing effects of mature and proneurotrophins may provide the opportunity to develop novel therapies that regulate the phenotype of macrophages in the context of HIV infection and perhaps other degenerative diseases.

Caseworker Visitation After Reunification and Children's Reentry Into Foster Care: A Survival Analysis.

To prevent children from reentering the welfare system, it is crucial to understand the role of caseworker visits after reunification on reentry and identify the factors related to reentry. Utilizing the administrative data of one Mid-Atlantic state, children who reunified with their families between July 2016 and June 2020 were selected as the study sample (N = 3,510). Reentry rates were higher for children who did not have caseworker visits after reunification than for those who did. The survival analysis revealed that male children, living in metropolitan areas, having a prior history of removal, having a behavioral issue, and court-ordered return increased the risk of reentry, while Black children, older children, having a last placement as trial home visit, and caseworker visits after reunification decreased the risk of reentry. The study suggests formally outlining policies for post-reunification caseworker visits and increasing collaboration between the child welfare system and court system.

A parental communication assessment initiative in the paediatric cardiovascular ICU.

OBJECTIVE: Challenges to communication between families and care providers of paediatric patients in intensive care units (ICU) include variability of communication preferences, mismatched goals of care, and difficulties carrying forward family preferences from provider to provider. Our objectives were to develop and test an assessment tool that queries parents of children requiring cardiac intensive care about their communication preferences and to determine if this tool facilitates patient-centred care and improves families' ICU experience. DESIGN: In this quality improvement initiative, a novel tool was developed, the Parental Communication Assessment (PCA), which asked parents with children hospitalised in the cardiac ICU about their communication preferences. Participants were prospectively randomised to the intervention group, which received the PCA, or to standard care. All participants completed a follow-up survey evaluating satisfaction with communication. MAIN RESULTS: One hundred thirteen participants enrolled and 56 were randomised to the intervention group. Participants who received the PCA preferred detail-oriented communication over big picture. Most parents understood the daily discussions on rounds (64%) and felt comfortable expressing concerns (68%). Eighty-six percent reported the PCA was worthwhile. Parents were generally satisfied with communication. However, an important proportion felt unprepared for difficult decisions or setbacks, inadequately included or supported in decision-making, and that they lacked control over their child's care. There were no significant differences between the intervention and control groups in their communication satisfaction results. CONCLUSIONS: Parents with children hospitalised in the paediatric ICU demonstrated diverse communication preferences. Most participants felt overall satisfied with communication, but individualising communication with patients' families according to their preferences may improve their experience.

The Williams and McCoy model of motivational spirited cognitive behavioral change communication.

PURPOSE: The Williams and McCoy Motivational Spirited Cognitive Behavioral Change Communication (MIS-CBC) is an innovative model combining the spirit of motivational interviewing (MI) communication, and cognitive behavioral therapy (CBT) as a patient-centered care model to improve continuity of care while enabling patients to progress during therapy. CONCLUSIONS: Incorporating this model into Psychiatric Mental Health Advance Practice Nurse practice allows for provision of best practice with populations experiencing low motivation and subject to dropout. The model aims to improve patient motivation and engagement of CBT to achievement "full dose" CBT with more flexibility to significantly improve patient outcomes, particularly with patient populations subject to interruptions in psychotherapy. PRACTICE IMPLICATIONS: The Williams and McCoy MIS-CBC model has implications in areas of both practice and academia addressing episodic psychotherapy in populations where interruptions and dropout frequently occur.

Canadian Consensus Guidelines for the Diagnosis and Treatment of Autoimmune Encephalitis in Adults.

Autoimmune encephalitis is increasingly recognized as a neurologic cause of acute mental status changes with similar prevalence to infectious encephalitis. Despite rising awareness, approaches to diagnosis remain inconsistent and evidence for optimal treatment is limited. The following Canadian guidelines represent a consensus and evidence (where available) based approach to both the diagnosis and treatment of adult patients with autoimmune encephalitis. The guidelines were developed using a modified RAND process and included input from specialists in autoimmune neurology, neuropsychiatry and infectious diseases. These guidelines are targeted at front line clinicians and were created to provide a pragmatic and practical approach to managing such patients in the acute setting.

Factors Associated With Permanency for Children in Out-Of-Home Placement: A Survival Analysis.

Achieving permanency is a main goal of the child welfare system. To promote timely achievement of permanency, it is important to understand the determinants associated with permanency outcomes. This study aims to examine the length of time children spend in foster care and identify factors associated with achievement of permanency using administrative data from one state spanning a six-year timeframe and including a final sample of 1,874 children. Determinants associated with achievement of permanency were examined through multivariate survival analyses using Cox proportional hazards regression models. The median length of time in days to achieve permanency was: 188 for reunification, 505 for guardianship, and 932 for adoption. Race/ethnicity, age at removal, number of placement changes, number of siblings, having a removal family team decision meeting (FTDM), and placement type were significantly associated with achievement of permanency. Given the findings, this article proposes implications for practice and policy surrounding racial disproportionality, family engagement, kinship care, and placement stability.

COVID-19 in hospitalized adult patients with sickle cell disease: A 2020 US cohort using Cerner Real-World Data™ (CRWD).

We used Cerner Real-World Data™, representing hospital admission records from 2020, to examine patients with co-occurring sickle cell disease and COVID-19 by discharge disposition grouped as death/hospice versus transfers to other facilities, returned home, or left against medical advice. Among the death/hospice group, we found older age and higher rates of congestive heart failure and diabetes. There were also significant differences in tachypnea, mechanical ventilation, minimum O2 saturation, and length of stay with higher rates in the death/hospice group. Awareness of such factors and associated mortality risks for this population may aid in patient care.

Understanding nurse suicide using an ideation-to-action framework: An integrative review.

OBJECTIVE: The purpose of this integrative review was to explore, appraise and synthesize the current literature on correlates of suicide risk in nurses. DESIGN: Integrative literature review. DATA SOURCES: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Joanna Briggs Institute, PubMed, PsycInfo and Scopus electronic databases were searched for abstracts published between 2005 and 2020. Reference lists were hand searched. REVIEW METHODS: The integrative review was based on the Whittemore and Knafl review methodology. Primary qualitative and quantitative studies about suicidal behaviour in nurses published in peer-reviewed journals were included. The methodological quality of included articles was assessed using the Mixed Methods Assessment Tool. RESULTS: Separate correlates of risk and protective factors were identified for suicidal ideation, suicide attempt and death by suicide in nurses. IMPLICATIONS: Due to a number of factors at the individual, interpersonal and work levels, nurses are uniquely positioned to be at risk of dying by suicide. The ideation-to-action framework provides a theoretical guide to understand the interplay between correlates and the effect it has on increasing a nurses' capability for suicide. CONCLUSIONS: This review integrates the empirical literature to elucidate the concept of suicidal behaviour as it applies to nurses.

Ask questions (ASQ): Implementation of a question prompt list communication intervention in a network of outpatient medical oncology clinics.

OBJECTIVE: This descriptive, single-arm study assessed the implementation and patient perceptions of an evidence-based Question Prompt List (QPL), the ASQ brochure, across a network of oncology clinics in a diverse patient population. METHOD: The QPL was revised in collaboration with stakeholders. Implementation was assessed using the RE-AIM framework. Eligible patients were scheduled for a first appointment with an oncologist at any of eight participating clinics. All participants received the ASQ brochure and completed three surveys: one at baseline, one immediately before, and one following their appointment. Surveys assessed sociodemographic characteristics; communication-related outcomes (perceived knowledge, self-efficacy in interacting with physicians, trust in physicians, distress); and perceptions of the ASQ brochure. Analyses included descriptive statistics and linear mixed-effects models. RESULTS: Reach: Participants (n = 81) represented the diverse population served by the clinic network. EFFICACY: All outcomes improved significantly, with no significant differences by clinic site or patient race. Adoption: All eight invited clinics participated and recruited patients. Patient perceptions of the ASQ brochure were overwhelmingly positive. CONCLUSION: Implementation of the ASQ brochure was successful in this oncology clinic network providing care to a diverse patient population. PRACTICAL IMPLICATIONS: This evidence-based communication intervention can be implemented widely in similar medical contexts and populations.

Effects of pair housing on behavior, cortisol, and clinical outcomes during quarantine-like procedures for rhesus macaques (Macaca mulatta).

BACKGROUND: Compatible pair housing of macaques in research settings increases species-typical behaviors and facilitates beneficial social buffering. It is not yet established whether these benefits are maintained after intrafacility transfer and domestic quarantine, which are two stressors that can lead to behavioral and clinical abnormalities. METHODS: We evaluated 40 adolescent male rhesus macaques who were single- or pair-housed immediately following an intrafacility transfer. We measured behavior, fecal cortisol, body weight, and diarrhea occurrence. Body weight and diarrhea occurrence were also retrospectively analyzed in an additional 120 adolescent rhesus who underwent a similar transfer. RESULTS AND CONCLUSIONS: Pair-housed macaques exhibited less of some undesirable behaviors (e.g., self-clasping) and experienced less diarrhea than single-housed subjects; however, no significant differences in cortisol levels or alopecia measures were found. The demonstrated beneficial effects of pair housing for rhesus macaques following intrafacility transfer and adjustment suggest pairing upon arrival at a new facility will bolster animal welfare.

Risk factors for appendicular osteosarcoma occurrence in large and giant breed dogs in western Canada.

Objective: Risk factors for the development of canine appendicular osteosarcoma (OSA) have been investigated in numerous studies, but with contradictory results. The aim of this study was to analyze weight, age, breed, sex, neuter status, body condition score, and previous lameness in a population of large and giant breed dogs in western Canada with and without appendicular OSA. Animals and procedure: Medical records of 227 large or giant breed dogs diagnosed with appendicular OSA were compared to records from a control population of 454 large and giant breed dogs from the years 2000 to 2020. Results: Gonadectomized dogs, body condition score (BCS), and a history of lameness condition(s) (other than OSA) were associated with increased odds for presentation with OSA. Breeds shown to have increased odds for appendicular OSA occurrence included Rottweilers and Great Danes relative to Labrador retrievers. Conclusion and clinical relevance: Obesity and lameness appear to be independently associated with appendicular osteosarcoma. This study demonstrated that spayed females had the greatest risk compared to other sex and neuter status combinations; further investigation of these factors would be beneficial.

Facteurs de risque d'apparition d'ostéosarcome appendiculaire chez les chiens de grandes races et de races géantes dans l'Ouest canadien. Objectif: Les facteurs de risque de développement de l'ostéosarcome (OSA) appendiculaire canin ont été étudiés dans de nombreuses études, mais avec des résultats contradictoires. Le but de cette étude était d'analyser le poids, l'âge, la race, le sexe, la stérilisation, le score d'état corporel et les boiteries antérieures dans une population de chiens de grande race et de race géante de l'Ouest canadien avec et sans OSA appendiculaire. Animaux et procédure: Les dossiers médicaux de 227 chiens de grande race ou de race géante diagnostiqués avec l'OSA appendiculaire ont été comparés aux dossiers d'une population témoin de 454 chiens de grande race et de race géante des années 2000 à 2020. Résultats: Les chiens gonadectomisés, le score d'état corporel (BCS) et des antécédents de condition(s) de boiterie (autres que l'OSA) étaient associés à une probabilité accrue de présentation d'OSA. Les races dont le risque d'apparition d'OSA appendiculaire était plus élevé comprenaient les Rottweilers et les Grands Danois par rapport aux Labrador retrievers. Conclusion et pertinence clinique: L'obésité et la boiterie semblent être indépendamment associées à l'ostéosarcome appendiculaire. Cette étude a démontré que les femelles stérilisées présentaient le plus grand risque par rapport aux autres combinaisons de sexe et de statut neutre, une enquête plus approfondie sur ces facteurs serait bénéfique.(Traduit par Dr Serge Messier).
