Incidence, severity and prognosis associated with hypernatremia in dogs and cats.

BackgroundHypernatremia has been associated with substantial morbidity and death in human patients. The incidence and importance of hypernatremia in dogs and cats has not been determined.Hypothesis/objectivesTo describe the incidence of and prognosis associated with hypernatremia in dogs and cats at a university teaching hospital.AnimalsA total of 16,691 dogs and 4,211 cats with measured blood or serum sodium concentration.MethodsRetrospective study. Medical records of animals with a blood or serum sodium concentration measured during a 60-month period were reviewed to determine the severity of hypernatremia and its associated case fatality rate. Cases with moderate (11-15 mmol/L above the reference range) or severe hypernatremia (≥16 mmol/L above the reference range) were further reviewed.ResultsA total of 957 dogs (5.7%) and 338 cats (8.0%) were diagnosed with hypernatremia. Case fatality rates of dogs and cats with hypernatremia was 20.6 and 28.1%, respectively compared to 4.4 and 4.5% with a normal blood or serum sodium concentration (P < .0001). The magnitude of hypernatremia was linearly associated with a higher case fatality rate (P < .0001). Hypernatremia was associated with a higher case fatality rate than hyponatremia. Among the animals with moderate or severe hypernatremia, 50% of dogs and 38.5% of cats presented with community-acquired hypernatremia, and 50% of dogs and 61.5% of cats developed hospital-acquired hypernatremia.Conclusions and clinical importanceHypernatremia was found infrequently in this population but was associated with increased case fatality rates in dogs and cats. Presence and severity of hypernatremia might be useful as a prognostic indicator

Diagnostic yield of cytologic analysis of pericardial effusion in dogs.

BackgroundPericardial effusion cytology is believed by many to be of limited value, yet few studies have evaluated its diagnostic utility.ObjectivesTo determine the diagnostic utility of cytologic analysis of pericardial effusion in dogs and to determine if consideration of additional data could improve the diagnostic yield.AnimalsTwo hundred and fifty-nine dogs with cytologic analysis of pericardial effusion performed between April 1990 and June 2012.MethodsElectronic medical records from a university teaching hospital were retrospectively reviewed; signalment, complete blood count, serum biochemistry, cytologic analysis of pericardial effusion, and echocardiographic data were recorded. Cytology was classified as diagnostic (infectious or neoplastic) or nondiagnostic (hemorrhagic or other) and groups were compared with multiple Student's t-tests.ResultsCytology was grouped as nondiagnostic (92.3%) or diagnostic (7.7%) and characterized as hemorrhagic (90%), neoplastic (4.6%), infectious (3.1%), or other (2.3%). Overall cytologic analysis of pericardial effusion diagnostic utility was 7.7% and increased to 20.3% if the effusion hematocrit (HCT) <10%; echocardiographic evidence of a mass did not result in a significant increase in the diagnostic utility.Conclusions and clinical importanceThe diagnostic utility of cytologic analysis of canine pericardial effusion is variable depending on the underlying etiology. In this group of dogs, the diagnostic yield of cytologic analysis was greater for pericardial effusion samples in which the HCT was less than 10%

Economic inequalities in the effectiveness of a primary care intervention for depression and suicidal ideation.

BACKGROUND: Economic disadvantage is associated with depression and suicide. We sought to determine whether economic disadvantage reduces the effectiveness of depression treatments received in primary care. METHODS: We conducted differential-effects analyses of the Prevention of Suicide in Primary Care Elderly: Collaborative Trial, a primary-care-based randomized, controlled trial for late-life depression and suicidal ideation conducted between 1999 and 2001, which included 514 patients with major depression or clinically significant minor depression. RESULTS: The intervention effect, defined as change in depressive symptoms from baseline, was stronger among persons reporting financial strain at baseline (differential effect size = -4.5 Hamilton Depression Rating Scale points across the study period [95% confidence interval = -8.6 to -0.3]). We found similar evidence for effect modification by neighborhood poverty, although the intervention effect weakened after the initial 4 months of the trial for participants residing in poor neighborhoods. There was no evidence of substantial differences in the effectiveness of the intervention on suicidal ideation and depression remission by economic disadvantage. CONCLUSIONS: Economic conditions moderated the effectiveness of primary-care-based treatment for late-life depression. Financially strained individuals benefited more from the intervention; we speculate this was because of the enhanced treatment management protocol, which led to a greater improvement in the care received by these persons. People living in poor neighborhoods experienced only temporary benefit from the intervention. Thus, multiple aspects of economic disadvantage affect depression treatment outcomes; additional work is needed to understand the underlying mechanisms

Prospective Evaluation of Cardiopulmonary Resuscitation Performed in Dogs and Cats According to the RECOVER Guidelines. Part 1: Prognostic Factors According to Utstein-Style Reporting.

Factors associated with positive cardiopulmonary resuscitation (CPR) outcomes defined according to the veterinary Utstein-style CPR reporting guidelines have not been described since implementation of the Reassessment Campaign on Veterinary Resuscitation (RECOVER) CPR clinical guidelines in 2012. The aims of this study were to assess factors associated with positive CPR outcomes at a U.S. veterinary teaching hospital, to re-evaluate these factors since implementation of the RECOVER guidelines compared to reported factors prior to their publication, and to identify potential additional factors since guideline publication. One-hundred and seventy-two dogs and 47 cats that experienced cardiopulmonary arrest (CPA) and had CPR performed were prospectively included in this observational study. Supervising clinicians were asked to complete a data form on CPR events immediately following completion of CPR efforts. Multivariable logistic regression was used to evaluate the effect of twenty hospital, animal, and arrest variables on the three patient outcomes "any return of spontaneous circulation (ROSC)," "sustained ROSC," and survival to hospital discharge. Cats had significantly higher odds to achieve any ROSC [OR (95%CI) 2.72 (1.12-6.61), p = 0.028] and survive to hospital discharge than dogs [OR (95%CI) 4.87 (1.52-15.58), p = 0.008]. Patients had significantly lower odds of achieving any ROSC if CPA occurred during nighttime hours [OR (95%CI) nighttime = 0.52 (0.27-0.98), p = 0.043], and higher odds if CPA was witnessed [OR (95%CI) 3.45 (1.57-7.55), p = 0.002], if less people were involved in CPR efforts [OR (95%CI) 0.8 (0.66-0.96), p = 0.016], if pulses were palpable during CPR [OR (95%CI) 9.27 (4.16-20.63), p < 0.0005], and if an IV catheter was already in place at the time of CPA [OR (95%CI) 5.07 (2.12-12.07), p = 0.0003]. Odds for survival to hospital discharge were significantly higher if less people were involved in CPR efforts [OR (95%CI) 0.65 (0.46-0.91), p = 0.013] and for patients of the anesthesia service [OR (95%CI) 14.82 (3.91-56.17), p = 0.00007]. Overall, factors associated with improved CPR outcomes have remained similar since incorporation of RECOVER guidelines into daily practice. Witnessed CPA events and high-quality CPR interventions were associated with positive patient outcomes, emphasizing the importance of timely recognition and initiation of CPR efforts. An optimal CPR team size has yet to be determined

The effects of exposure to images of others’ suffering and vulnerability on altruistic, trust-based, and reciprocated economic decision-making

In this paper we explored the effects of exposure to images of the suffering and vulnerability of others on altruistic, trust-based, and reciprocated incentivized economic decisions, accounting for differences in participants’ dispositional empathy and reported in-group trust for their recipient(s). This was done using a pictorial priming task, framed as a memory test, and a triadic economic game design. Using the largest experimental sample to date to explore this issue, our integrated analysis of two online experiments (total N = 519), found statistically consistent evidence that exposure to images of suffering and vulnerability (vs. neutral images) increased altruistic in-group giving as measured by the “triple dictator game”, and that the manipulation was significantly more effective in those who reported lower trust for their recipients. The experimental manipulation also significantly increased altruistic giving in the standard “dictator game” and trust-based giving in the “investment game”, but only in those who were lower in in-group trust and also high in affective or cognitive empathy. Complementary qualitative evidence revealed the strongest motivations associated with increased giving in the experimental condition were greater assumed reciprocation and a lower aversion to risk. However, no consistent effects of the experimental manipulation on participants’ reciprocated decisions were observed. These findings suggest that, as well as altruistic decision-making in the “triple dictator game”, collaboratively witnessing the suffering of others may heighten trust-based in-group giving in the “investment game” for some people, but the effects are heterogeneous and sensitive to context

Why do people with mental distress have poor social outcomes? Four lessons from the capabilities approach

Macro level data indicate that people experiencing mental distress experience poor health, social and economic outcomes. The sociology of mental health has a series of dominant competing explanations of the mechanisms at personal, social and structural levels that generate these poor outcomes. This article explains the limitations of these approaches and takes up the challenge of Hopper (2007) who in this journal proposed the capabilities approach as a means of normatively reconceptualising the experiences of people with mental distress, with a renewed focus on agency, equality and genuine opportunity. Using an innovative methodology to operationalise the capabilities approach, findings from an in-depth qualitative study exploring the lived experiences of twenty-two people with recent inpatient experience of psychiatric units in Scotland are presented. The paper demonstrates that the capabilities approach can be applied to reconceptualise how unjust social outcomes happen for this social group. It distinguishes how the results of using a capabilities approach to analysis are distinct from established dominant analytical frameworks through four added features: a focus on actual lived outcomes; the role of capabilities as well as functionings; being normative; and incorporating agency. The capabilities approach is found to be an operationalisable framework; the findings have implications for professionals and systems in the specific context of mental health; and the capabilities approach offers a fertile basis for normative studies in wider aspects of health and wellbeing

Heart versus Head: Differential Bodily Feedback Causally Alters Economic Decision-making

Metaphorically, altruistic acts, such as monetary donations, are said to be driven by the heart, whereas sound financial investments are guided by reason, embodied by the head. In a unique experiment, we tested the effects of these bodily metaphors using biofeedback and an incentivized economic decision-making paradigm. Participants played a repeated investment game with a simulated partner, alternating between tactical investor and altruistic investee. When making decisions, participants received counterbalanced visual feedback from their own or a simulated partner’s heart or head, as well as no feedback. As investor, participants transferred a greater proportion of their endowments when exposed to visual feedback from their own head than to feedback from their own heart or no feedback at all. These effects were not observed when the source of the feedback was the simulated partner. As investee, heart feedback predicted greater altruistic returns than head or no feedback, but this effect did not differ based on source (own vs partner). Consistent with a dual-process framework, we suggest that people may be encouraged to invest more or be more altruistic when receiving bodily feedback from conceptually diametric sources

Any space left? Homeless resistance by place-type in Los Angeles County

This study develops a more nuanced concept of homeless resistance, incorporating a range of resistance behaviors (exit, adaptation, persistence, and voice) that bridge the gap between current frameworks that either romanticize or ignore it. We also consider the possibility that different kinds of space may theoretically allow for different kinds of resistance. To this end, we employ an ecological approach to homeless space by classifying Los Angeles County into three place-types (prime, transitional, and marginal). We empirically consider the issue of resistance within the hardening context among a group of 25 homeless informants, focusing on whether and how some of them have exercised their voices and sought to ameliorate one or more aspects of their situation, as well as how resistance may vary by place-type

Liberating the NHS; commissioning, outsourcing and a new politics debate

In the short months following the result of the UK 2010 General election, a new Government White Paper has been released entitled: Equity and Excellence: Liberating the NHS (Department of Health (DH), 2010a). It strives to distance itself from previous health-care proposals (DH, 2009), yet if the initiatives of this latest paper are combined against previous initiatives, also using high impact declarative terms, such as competition and choice, it is clear that little has changed and more important principles than saving money are at risk
