Pilot cadaveric study on the feasibility of cricothyroidotomy and the associated complications in 30 cats.

Objectives: The study's primary goal was to assess the feasibility of the cricothyroidotomy technique (CTT) in cats and evaluate its success rate (i.e., secure airway access). Secondary outcomes were the assessment of the subjective difficulty of airway access based on body score condition and weight. Further secondary outcomes consisted of procedural time and scoring of associated complications. The current study hypothesized that the CTT procedure would provide secure airway access with a reasonable success rate. Materials and methods: A prospective experimental study assessing the performance of CTT and associated complications was conducted on 30 feline cadavers. A procedural datasheet was completed to subjectively grade difficulty of landmark palpation, guide placement and tube placement and expected success of the procedure. A dissection was then performed post-procedure by a blinded observer to evaluate for any associated damages. Results: CTT was successful in securing an airway in 100% of the cats. The time to completion of the CTT was rapid, with a median time of 49 s (ranging from 31 to 90 s) for securing an airway. Of importance, this procedure was judged to be overall easy (median "ease of procedure score" of 7/10; ranging from 3 to 10) by the experimenters. The post-procedural lesion rate was elevated (76.7%) in this population of cats, though based on the lesion scores, was deemed mild in 73.9% of the cases. Clinical significance: CTT warrants consideration as the primary option for emergency front-of-neck airway access for cats although further studies are necessary.

Bile composition of healthy cats and cats with suspected hepatobiliary disease using point-of-care analyzers: A prospective preliminary study.

Although hepatobiliary disease is common in cats, little is known about the bile composition in either these diseased states or in healthy cats. The objectives of this study were to evaluate several analytes from the bile of healthy cats and to investigate the usefulness of measuring these variables to predict bacterial cholangitis. Cats were prospectively enrolled and divided into 3 groups: 21 healthy cats (group 1) and 14 cats with suspected hepatobiliary disease: 9 without bacterial biliary infection (group 2) and 5 with bacterial biliary infection (group 3). Percutaneous ultrasound-guided cholecystocentesis was conducted on each cat. Bile cytology and culture were carried out and bile was analyzed for pH, lactate, and glucose levels using several point-of-care (POC) devices. Reference values for several bile analytes in healthy cats were calculated and are presented in this study. Neither the pH (P = 0.88) nor the lactate concentration (P = 0.85) was significantly different among the 3 groups. Sodium concentration was significantly higher in group 3 than in group 2 (P < 0.05). Bile pH, lactate, and glucose levels were unable to predict the presence of a bacterial infection in the bile.

La composition de la bile est méconnue tant chez les chats sains que chez les chats atteints de maladies hépatobiliaires bien que ces maladies soient fréquentes. Les objectifs de cette étude étaient d'évaluer plusieurs paramètres dans la bile de chats sains et d'investiguer l'utilité de ces derniers comme marqueurs prédictifs de cholangite bactérienne. Les chats ont été recrutés prospectivement et répartis en trois groupes : 21 chats sains (groupe 1); et 14 chats avec maladie hépatobiliaire suspectée : 9 sans infection biliaire (groupe 2) et 5 avec infection bactérienne biliaire (groupe 3). Une cholécystocentèse a été réalisée sur chaque chat. La bile a été utilisée pour cytologie, culture et analyses biochimiques incluant le pH, le lactate et le glucose avec des appareils au chevet du patient. Les valeurs de référence de plusieurs paramètres biliaires chez les chats sains ont été calculées et sont présentées dans cette étude. Le pH (P = 0,88) et la concentration en lactate (P = 0,85) n'étaient pas significativement différents entre les 3 groupes. La concentration en sodium était significativement plus élevée dans le groupe 3 comparée aux groupe 2 (P < 0,05). Les concentrations en lactate et glucose ainsi que le pH ne permettaient pas de prédire une infection bactérienne dans la bile.(Traduit par les auteurs).

Prevalence and management of pain in dogs in the emergency service of a veterinary teaching hospital.

A prospective, observational, cross-sectional study documenting the prevalence of pain in dogs presented to the emergency service of a veterinary teaching hospital and their handling (times to triage, examination, treatment) was conducted. Pain was assessed and compared using a validated and an unvalidated pain assessment scale. Sedation was monitored using a validated scale. A first evaluation was completed in 109 dogs. A second evaluation was completed for 95 dogs: 36 (38%) were identified as painful and 53% (19/36) were provided analgesia in the clinic. The remainder either did not receive analgesia (6/36, 17%) or were prescribed an analgesic for administration at home (11/36, 31%). Of dogs receiving analgesia in the clinic, most showed a decrease in pain score (15/19, 79%). Pain assessment scales were positively correlated (r = 0.69, P < 0.0001) but the unvalidated scale was insensitive in discriminating changes. Between painful and non-painful dogs, progression did not differ: admission to treatment [P = 0.96, 95% confidence interval (CI): -23 to 22 minutes] and examination to treatment (P = 0.73, 95% CI: 14 to 20 minutes). Suboptimal analgesic use suggests focused training in pain assessment and analgesic use guided by a validated pain assessment scale, is warranted.

Prévalence et gestion de la douleur chez des chiens présentés au service d'urgence d'un hôpital d'enseignement vétérinaire. Une étude prospective, observationnelle et transversale a été réalisée pour documenter la prévalence de la douleur chez les chiens présentés au service d'urgence d'un hôpital universitaire vétérinaire ainsi que leur gestion (délai pour le triage, examen et traitement). Une échelle validée d'évaluation de la douleur a été utilisée pour évaluer la douleur à l'admission et suivant le traitement en clinique. A titre de comparaison, une échelle non validée d'évaluation de la douleur a également été utilisé et le degré de sédation a été documenté à l'aide d'une échelle de sédation validée. Une première évaluation a été complétée chez 109 chiens. Sur les 95 chiens pour lesquels une deuxième évaluation a été complétée, 36 (38 %) ont été identifiés comme étant en douleur et 53 % (19/36) ont reçu de l'analgésie en clinique. Les chiens restants n'ont soit pas reçu d'analgésie (6/36, 17 %) ou ont reçu une prescription pour un traitement analgésique à la maison (11/36, 31 %). Pour les chiens ayant reçu un traitement analgésique en clinique, la grande majorité ont démontré une diminution de leur score de douleur (15/19, 79 %). Une corrélation positive entre les deux échelles d'évaluation de la douleur était présente (r = 0,69, P < 0,0001), mais l'échelle non validée n'était pas sensible pour distinguer les changements de score de douleur. Il n'y avait pas de différence significative entre les chiens en douleur et non en douleur concernant le délai entre l'admission et le traitement (P = 0,96, 95 % CI : ­23 à 22 minutes) ou entre l'examen et le traitement (P = 0,73, 95 % CI : 14 à 20 minutes). L'administration d'analgésie était suboptimal dans la population étudiée, suggérant qu'un entraînement ciblé pour reconnaître et traiter la douleur à l'aide d'une échelle validée est recommandé.(Traduit par Dr Frédérik Rousseau-Blass).

Facial expressions of pain in cats: the development and validation of a Feline Grimace Scale.

Grimace scales have been used for pain assessment in different species. This study aimed to develop and validate the Feline Grimace Scale (FGS) to detect naturally-occurring acute pain. Thirty-five client-owned and twenty control cats were video-recorded undisturbed in their cages in a prospective, case-control study. Painful cats received analgesic treatment and videos were repeated one hour later. Five action units (AU) were identified: ear position, orbital tightening, muzzle tension, whiskers change and head position. Four observers independently scored (0-2 for each AU) 110 images of control and painful cats. The FGS scores were higher in painful than in control cats; a very strong correlation with another validated instrument for pain assessment in cats was observed (rho = 0.86, p < 0.001) as well as good overall inter-rater reliability [ICC = 0.89 (95% CI: 0.85-0.92)], excellent intra-rater reliability (ICC > 0.91), and excellent internal consistency (Cronbach's alpha = 0.89). The FGS detected response to analgesic treatment (scores after analgesia were lower than before) and a cut-off score was determined (total pain score > 0.39 out of 1.0). The FGS is a valid and reliable tool for acute pain assessment in cats.

Systemic disseminated Neospora caninum infection with cutaneous lesions as the initial clinical presentation in a dog.

This report describes a disseminated Neospora caninum infection with cutaneous involvement as the primary presenting clinical sign, in an apparently immunocompetent 7-year-old, spayed female boxer dog. The dog had an 8-day history of progressive lethargy associated with the appearance of multiple cutaneous and ulcerated masses, followed by an acute deterioration of her clinical status. Blood analysis revealed thrombocytopenia, increased liver enzyme activity, and partial thromboplastin time. Disseminated intravascular coagulation was suspected. Tachyzoites were identified on cutaneous cytology and species was determined by polymerase chain reaction (PCR) assays on blood and cerebrospinal fluid. The post-mortem evaluation revealed involvement of the neurological system, liver, lung, and skin.

Infection systémique disséminée par Neospora caninum avec lésions cutanées comme présentation clinique initiale chez un chien. Ce cas clinique décrit une infection disséminée par Neospora caninum, avec atteinte cutanée comme présentation clinique initiale, chez une femelle Boxer stérilisée de 7 ans apparemment immunocompétente. La chienne présentait une léthargie progressive depuis 8 jours associée à l'apparition de multiples masses cutanées ulcérées, suivie d'une détérioration aigüe de son état général. L'analyse sanguine a révélé une thrombocytopénie, une augmentation des enzymes hépatiques et du temps de thromboplastine partiel. Une coagulation intravasculaire disséminée a été soupçonnée. Des tachyzoïtes ont été mis en évidence sur la cytologie cutanée et l'espèce a été identifiée par PCR sur le sang et le liquide céphalorachidien. L'évaluation post-mortem a révélé une atteinte du système neurologique, du foie, des poumons et de la peau.(Traduit par les auteurs).

The Will Reconsidered: Hard Choices in Living Organ Donation.

In the following article, we illustrate an interview between a living donor advocate and a potential living organ donor in which the donor faced a hard choice: the reasons to donate and the reasons not to donate were equally persuasive. In the discussion that follows, we analyze the act of willing, what differentiates coercion and willing, and how the case study highlights a different, but by no means rare, instance in which donors feel paralyzed by the choice at hand. In such cases, we suspect that donor advocates either do not approve the potential donor for transplantation or simply remain neutral. But we think that this approach benefits neither the donor nor the recipient. We conclude this study with recommendations for living donor advocates, providing questions that might solicit donors' deeper values and suggesting that in these situations donors may benefit from additional time for reflection.

Chylous ascites associated with abdominal trauma and intestinal resection-anastomosis in a pet ferret (Mustela putorius furo).

CASE DESCRIPTION A 10-week-old 0.73-kg (1.6-lb) castrated male domestic ferret (Mustela putorius furo) was referred for exploratory laparotomy because of pneumoperitoneum and possible septic peritonitis after being bitten by the owner's dog. CLINICAL FINDINGS Abdominal exploration revealed a large laceration of the duodenum, tears of the jejunal mesentery, and 2 small tears in the abdominal wall. Chylous abdominal effusion developed 48 hours after surgery. TREATMENT AND OUTCOME Postoperative care included supportive treatment, analgesia, and antimicrobials. An abdominal drain was placed during the laparotomy and enabled monitoring of abdominal fluid production. Enteral feeding was provided through an esophagostomy tube. The chylous fluid production rapidly decreased after treatment with octreotide was initiated, and the ferret improved. Chyloabdomen resolved after 8 days of hospitalization and medical treatment. CLINICAL RELEVANCE Findings suggested that chylous ascites can potentially develop secondary to blunt abdominal trauma in ferrets. In this ferret, chyloabdomen was successfully treated with octreotide administration and abdominal drainage.

Complexity Analysis of Decision-Making in the Critically Ill.

RATIONALE: Despite multiple trials of interventions to improve end-of-life care of the critically ill, there is a persistent lack of understanding of factors associated with barriers to decision-making at the end of life. OBJECTIVE: To apply the principles of complexity science in examining the extent to which transitions to end-of-life care can be predicted by physician, family, or patient characteristics; outcome expectations; and the evaluation of treatment effectiveness. METHODS: A descriptive, longitudinal study was conducted in 3 adult intensive care units (ICUs). Two hundred sixty-four family surrogates of patients lacking decisional capacity and the physicians caring for the patients were interviewed every 5 days until ICU discharge or patient death. MEASUREMENTS: Characteristics of patients, physicians, and family members; values and preferences of physicians and family; and evaluation of treatment effectiveness, expectations for patient outcomes, and relative priorities in treatment (comfort vs survival). The primary outcome, focus of care, was categorized as (1) maintaining a survival orientation (no treatment limitations), (2) transitioning to a stronger palliative focus (eg, some treatment limitations), or (3) transitioning to an explicit end-of-life, comfort-oriented care plan. MAIN RESULTS: Physician expectations for survival and future cognitive status were the only variables consistently and significantly related to the focus of care. Neither physician or family evaluations of treatment effectiveness nor what was most important to physicians or family members was influential. CONCLUSION: Lack of influence of family and physician views, in comparison to the consistent effect of survival probabilities, suggests barriers to incorporation of individual values in treatment decisions.

Cancer patient age and family caregiver bereavement outcomes.

PURPOSE: This study drew on life course theory to argue that the strains of cancer caregiving and bereavement are modified by the age of the patient. We expected that caregivers of middle-aged patients would be more distressed than caregivers of older patients. METHODS: This panel study conducted 199 interviews with family caregivers of advanced cancer patients; first following diagnosis and again shortly after the patient's death. RESULTS: Among caregivers of middle-aged patients (40-59), grief mediated the relationship between baseline caregiving and bereavement depressed mood, with grief increasing risk of depression in bereavement. Among caregivers of young-old patients (60-79), grief had a suppressor effect on the relationship between caregiving and bereavement depressed mood, showing greater distress during caregiving than at bereavement. CONCLUSIONS: Caregiving for middle-aged cancer patients may increase the risk for severe grief and depression, whereas caregivers of young-old cancer patients appeared to experience relief at bereavement. After bereavement, continued observation may be warranted for caregivers of a middle-aged patient; grief, added to the ongoing demands of their lives (which may include those left behind by a middle-aged patient), may put such caregivers at risk for greater psychological and emotional distress.

Coexistent arteriovenous malformation and hippocampal sclerosis.

Cavernous angiomas or cavernomas have been occasionally described in patients presenting with medically intractable epilepsy. Reports of cavernomas associated with a second pathology potentially causative of seizures have rarely been documented; most commonly, the second pathology is focal cortical dysplasia or less frequently, hippocampal sclerosis. To our knowledge, cases of arteriovenous malformation arising in this clinical setting and associated with hippocampal sclerosis have not been previously described. We report a 56-year-old woman who initially presented at age 24years with staring spells. Imaging studies revealed an arteriovenous malformation in the right parietal lobe. At age 51years, she represented with signs and symptoms related to a hemorrhage from the malformation. The patient underwent Gamma Knife radiosurgery (Elekta AB, Stockholm, Sweden) of the lesion. She subsequently developed seizures, refractory to medical management. MRI studies showed atrophy in the right hippocampus. She underwent resection of the right parietal lobe and hippocampus. Histopathologic examination of the right parietal lesion revealed an arteriovenous malformation marked by focally prominent vascular sclerosis, calcification and adjacent hemosiderin deposition. The hippocampus was marked by prominent neuronal loss and gliosis in the CA1 region, consistent with CA1 sclerosis or hippocampal sclerosis International League Against Epilepsy type 2.

Grief and risk of depression in context: the emotional outcomes of bereaved cancer caregivers.

We investigated the relationships of grief and depression to cancer caregiving in early bereavement. We began with three expectations: (a) each outcome would reflect different situational predictors, (b) grief would be more directly related to such predictors, and (c) components of grief would relate differently to the caregiving context and depressed mood. We conducted telephone interviews with family caregivers of incurable cancer patients from two hospitals. A total of 199 family caregivers were interviewed at the time of the patient's diagnosis and reinterviewed 3 months after the patient's death. Results showed grief severity was predicted by caregiving circumstances, but bereavement depressed mood was largely unrelated to caregiving. Grief was the main predictor of depressed mood and mediated almost all other effects. We conclude that while grief may trigger depression, the dissimilar connection to context means that the two emotional states should not be equated based purely on similarity of expression.

Preferences for aggressive care in underserved populations with advanced-stage lung cancer: looking beyond race and resuscitation.

PURPOSE: This paper examines the relationship between race, religiousness, spiritual well-being, antitumor treatment and preference for aggressive care among Black and White patients with advanced stage lung cancer receiving ambulatory cancer care in an urban setting. METHODS: A cross-sectional exploration of patients enrolled in a Cleveland-based longitudinal study after initial diagnosis of advanced lung cancer were interviewed in Cleveland regarding religiousness, spiritual well-being, preferences for cardiopulmonary resuscitation (CPR), goals of aggressive care, and willingness to tolerate adverse health states. Receipt of antitumor treatment was identified from medical records. RESULTS: We analyzed data from 67 Black and 129 White patients (N=196). Regression analysis for CPR showed that race was not associated with preference for CPR (OR=1.12, CI 0.44-2.85). The odds of choosing CPR were three times higher among patients receiving antitumor treatment (OR=3.26, CI 1.12-9.44). Greater willingness to endure adverse health states was associated with higher spiritual well-being scores (b=0.12, CI 0.01-0.25). Choosing goals to extend life versus relieve pain was higher among persons with higher spiritual well-being as well (RRR=1.08, CI 1.01-1.16), yet the relationship with religiousness was negative (RRR=0.46, CI 0.22-0.98). CONCLUSIONS: After controlling for multiple factors, race was associated only with CPR, but not with other measures of preference for aggressive care. In addition, receipt of active antitumor treatment was positively associated with preference for CPR and spiritual well-being was important to setting end-of-life care goals and perspectives. Future directions for tailoring end-of-life care decision-making initiatives should move beyond race and discussions of CPR alone and focus on a full spectrum of patient beliefs and preferences at the end of life.

Effect of a computerized brain exercise program on cognitive performance in older adults.

OBJECTIVES: Research indicates an association between stimulating mental activities and better memory performance as people age, but studies on computerized mental stimulation programs are limited. We explored whether computerized brain training exercises improved cognitive performance in older adults. METHODS: In local retirement communities, a convenience sample was randomized into an intervention group (N = 36), who used a computer program 5 days a week for 20-25 minutes each day, or a wait-list control group (N = 33). All were older adults without dementia (mean age: 81.8 years; SD: 6.1; 67% female). Neuropsychological testing was completed at baseline (Time 1), 2 months (Time 2), and 6 months (Time 3). Three cognitive domains (Immediate Memory, Delayed Memory, Language) were compared in the two groups as a function of time using mixed models. RESULTS: The intervention group used the computerized program (Brain Fitness, Dakim Inc., Santa Monica, CA) for an average of 43 (SD: 4.4) sessions by Time 2 and 81 (SD: 37.5) sessions by Time 3. Mixed models examining cognitive domains as function of time revealed significant group differences in Delayed Memory (F(2,72) = 4.7, p = 0.01) but not Immediate Memory and Language; no significant improvements were noted for the control group. Among all participants, anyone playing at least 40 sessions over the 6 months improved in all three domains (Immediate Memory, Delayed Memory, and Language). CONCLUSION: Participating in a computerized brain exercise program over 6 months improves cognitive abilities in older adults. These results extend literature indicating the benefit of training exercises, whether in a classroom format or via a computerized self-paced program.

Community-based participatory development of a community health worker mental health outreach role to extend collaborative care in post-Katrina New Orleans.

OBJECTIVES: The REACH NOLA Mental Health Infrastructure and Training Project (MHIT) aimed to reduce disparities in access to and quality of services for depression and posttraumatic stress disorder (PTSD) in post-Katrina New Orleans by developing a mental health outreach role for community health workers (CHWs) and case managers as a complement to the collaborative care model for depression treatment. INTERVENTION: Community agency leaders, academics, healthcare organizations, and CHWs engaged in a community participatory process to develop a CHW training program. DESIGN: A review of qualitative data including semi-structured interviews, project team conference calls, email strings, and meeting minutes was conducted to document CHW input into training and responses to implementation. RESULTS: CHW contributions resulted in a training program focused on community engagement, depression screening, education, referral assistance, collaboration with clinical teams, and self-care. CHWs reported use of screening tools, early client successes in spite of challenges with client engagement, increase in networking and collaboration with other community agencies and providers, and ongoing community hurricane recovery issues. CONCLUSIONS: This intervention development approach and model may be used to address post-disaster mental health disparities and as a complement to traditional implementation of collaborative care.

Primary care physicians' involvement in the cancer care of older long-term survivors.

OBJECTIVE: This study investigated survivors' reports of primary care physicians' (PCPs) involvement in three key cancer survivorship activities: discussing cancer history, whether the PCP initiated discussions, and whether discussions led to tests/procedures. METHOD: The sample included 215 older survivors whose health care was maintained in primary care. Logistic regression explored predictors of the three activities, including demographics, cancer characteristics, survivor/PCP association characteristics, health characteristics, and psychosocial well-being. RESULTS: Nearly two thirds of survivors indicated discussing cancer history; most said discussions were PCP initiated and nearly half said discussions resulted in tests/procedures. Predictors of discussing cancer history were African American race and more comorbid conditions. PCP-initiated discussions were related to older age, surviving breast cancer, more years in the PCP's practice, and having less general health worry. The tests/procedures model was not significant. CONCLUSIONS: As older survivors focused more on other health concerns, PCPs remained attentive to cancer issues, prompting discussions about history and ordering tests.

Effectiveness trial of an intensive communication structure for families of long-stay ICU patients.

BACKGROUND: Formal family meetings have been recommended as a useful approach to assist in goal setting, facilitate decision making, and reduce use of ineffective resources in the ICU. We examined patient outcomes before and after implementation of an intensive communication system (ICS) to test the effect of regular, structured formal family meetings on patient outcomes among long-stay ICU patients. METHODS: One hundred thirty-five patients receiving usual care and communication were enrolled as the control group, followed by enrollment of intervention patients (n = 346), from five ICUs. The ICS included a family meeting within 5 days of ICU admission and weekly thereafter. Each meeting discussed medical update, values and preferences, and goals of care; treatment plan; and milestones for judging effectiveness of treatment. RESULTS: Using multivariate analysis, there were no significant differences between control and intervention patients in length of stay (LOS), the primary end point. Similarly, there were no significant differences in indicators of aggressiveness of care or treatment limitation decisions (ICU mortality, LOS, duration of ventilation, treatment limitation orders, or use of tracheostomy or percutaneous gastrostomy). Exploratory analysis suggested that in the medical ICUs, the intervention was associated with a lower prevalence of tracheostomy among patients who died or had do-not-attempt-resuscitation orders in place. CONCLUSIONS: The negative findings of the main analysis, in combination with preliminary evidence of differences among types of unit, suggest that further examination of the influence of patient, family, and unit characteristics on the effects of a system of regular family meetings may be warranted. Despite the lack of influence on patient outcomes, structured family meetings may be an effective approach to meeting information and support needs.
