ABSTRACT Objective: to understand the woman's experience of becoming a mother of a child with special needs from cerebral palsy. Methodology: this was a qualitative, phenomenological hermeneutic study carried out in a municipality in the north of the State of Rio Grande do Sul, Brazil, with ten mothers who were caring for children/adolescent with cerebral palsy between April and June 2015. Phenomenological interviews were used to collect information. The interpretation included the hermeneutic approach. Results: the mother upon receiving the diagnosis of cerebral palsy goes through a reorganization of her habitual way of being-in-the-world to adapt herself to the new existential situation. From that moment on, she started to live according to the child's care. Conclusions: This study provides the possibility of reflection for health professionals in order to understand the whole process experienced by the mother, helping her in this new existential situation, understanding her in the phases that make up the process of adaptation to the condition of being the mother of a child with cerebral palsy.

RESUMO

Aversive affect is likely a key source of irrational human decision-making, but still, little is known about the neural circuitry underlying emotion-cognition interactions during social behavior. We induced incidental aversive affect via prolonged periods of threat of shock, while 41 healthy participants made investment decisions concerning another person or a lottery. Negative affect reduced trust, suppressed trust-specific activity in the left temporoparietal junction (TPJ), and reduced functional connectivity between the TPJ and emotion-related regions such as the amygdala. The posterior superior temporal sulcus (pSTS) seems to play a key role in mediating the impact of affect on behavior: Functional connectivity of this brain area with left TPJ was associated with trust in the absence of negative affect, but aversive affect disrupted this association between TPJ-pSTS connectivity and behavioral trust. Our findings may be useful for a better understanding of the neural circuitry of affective distortions in healthy and pathological populations.

RESUMO

BACKGROUND: There are conflicting data on the effects of antipsychotic medications on delirium in patients in the intensive care unit (ICU). METHODS: In a randomized, double-blind, placebo-controlled trial, we assigned patients with acute respiratory failure or shock and hypoactive or hyperactive delirium to receive intravenous boluses of haloperidol (maximum dose, 20 mg daily), ziprasidone (maximum dose, 40 mg daily), or placebo. The volume and dose of a trial drug or placebo was halved or doubled at 12-hour intervals on the basis of the presence or absence of delirium, as detected with the use of the Confusion Assessment Method for the ICU, and of side effects of the intervention. The primary end point was the number of days alive without delirium or coma during the 14-day intervention period. Secondary end points included 30-day and 90-day survival, time to freedom from mechanical ventilation, and time to ICU and hospital discharge. Safety end points included extrapyramidal symptoms and excessive sedation. RESULTS: Written informed consent was obtained from 1183 patients or their authorized representatives. Delirium developed in 566 patients (48%), of whom 89% had hypoactive delirium and 11% had hyperactive delirium. Of the 566 patients, 184 were randomly assigned to receive placebo, 192 to receive haloperidol, and 190 to receive ziprasidone. The median duration of exposure to a trial drug or placebo was 4 days (interquartile range, 3 to 7). The median number of days alive without delirium or coma was 8.5 (95% confidence interval [CI], 5.6 to 9.9) in the placebo group, 7.9 (95% CI, 4.4 to 9.6) in the haloperidol group, and 8.7 (95% CI, 5.9 to 10.0) in the ziprasidone group (P=0.26 for overall effect across trial groups). The use of haloperidol or ziprasidone, as compared with placebo, had no significant effect on the primary end point (odds ratios, 0.88 [95% CI, 0.64 to 1.21] and 1.04 [95% CI, 0.73 to 1.48], respectively). There were no significant between-group differences with respect to the secondary end points or the frequency of extrapyramidal symptoms. CONCLUSIONS: The use of haloperidol or ziprasidone, as compared with placebo, in patients with acute respiratory failure or shock and hypoactive or hyperactive delirium in the ICU did not significantly alter the duration of delirium.

RESUMO

BACKGROUND: Delirium during critical illness results from numerous insults, which might be interconnected and yet individually contribute to long-term cognitive impairment. We sought to describe the prevalence and duration of clinical phenotypes of delirium (ie, phenotypes defined by clinical risk factors) and to understand associations between these clinical phenotypes and severity of subsequent long-term cognitive impairment. METHODS: In this multicentre, prospective cohort study, we included adult (≥18 years) medical or surgical ICU patients with respiratory failure, shock, or both as part of two parallel studies: the Bringing to Light the Risk Factors and Incidence of Neuropsychological Dysfunction in ICU Survivors (BRAIN-ICU) study, and the Delirium and Dementia in Veterans Surviving ICU Care (MIND-ICU) study. We assessed patients at least once a day for delirium using the Confusion Assessment Method-ICU and identified a priori-defined, non-mutually exclusive phenotypes of delirium per the presence of hypoxia, sepsis, sedative exposure, or metabolic (eg, renal or hepatic) dysfunction. We considered delirium in the absence of hypoxia, sepsis, sedation, and metabolic dysfunction to be unclassified. 3 and 12 months after discharge, we assessed cognition with the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). We used multiple linear regression to separately analyse associations between the duration of each phenotype of delirium and RBANS global cognition scores at 3-month and 12-month follow-up, adjusting for potential confounders. FINDINGS: Between March 14, 2007, and May 27, 2010, 1048 participants were enrolled, eight of whom could not be analysed. Of 1040 participants, 708 survived to 3 months of follow-up and 628 to 12 months. Delirium was common, affecting 740 (71%) of 1040 participants at some point during the study and occurring on 4187 (31%) of all 13 434 participant-days. A single delirium phenotype was present on only 1355 (32%) of all 4187 participant-delirium days, whereas two or more phenotypes were present during 2832 (68%) delirium days. Sedative-associated delirium was most common (present during 2634 [63%] delirium days), and a longer duration of sedative-associated delirium predicted a worse RBANS global cognition score 12 months later, after adjusting for covariates (difference in score comparing 3 days vs 0 days: -4·03, 95% CI -7·80 to -0·26). Similarly, longer durations of hypoxic delirium (-3·76, 95% CI -7·16 to -0·37), septic delirium (-3·67, -7·13 to -0·22), and unclassified delirium (-4·70, -7·16 to -2·25) also predicted worse cognitive function at 12 months, whereas duration of metabolic delirium did not (1·14, -0·12 to 3·01). INTERPRETATION: Our findings suggest that clinicians should consider sedative-associated, hypoxic, and septic delirium, which often co-occur, as distinct indicators of acute brain injury and seek to identify all potential risk factors that may impact on long-term cognitive impairment, especially those that are iatrogenic and potentially modifiable such as sedation.

RESUMO

INTRODUCTION: Unfavorable attitudes and insufficient knowledge about donation after cardiac death among critical care providers can have important consequences for the appropriate identification of potential donors, consistent implementation of donation after cardiac death policies, and relative strength of support for this type of donation. The lack of reliable and valid assessment measures has hampered research to capture providers' attitudes. Design and Research Aims: Using stakeholder engagement and an iterative process, we developed a questionnaire to measure attitudes of donation after cardiac death in critical care providers (n = 112) and examined its psychometric properties. Exploratory factor analysis, internal consistency, and validity analyses were conducted to examine the measure. RESULTS: A 34-item questionnaire consisting of 4 factors (Personal Comfort, Process Satisfaction, Family Comfort, and System Trust) provided the most parsimonious fit. Internal consistency was acceptable for each of the subscales and the total questionnaire (Cronbach α > .70). A strong association between more favorable attitudes overall and knowledge ( r = .43, P < .001) provides evidence of convergent validity. Multivariable regression analyses showed that white race ( P = .002) and more experience with donation after cardiac death ( P < .001) were significant predictors of more favorable attitudes. CONCLUSION: Study findings support the utility, reliability, and validity of a questionnaire for measuring attitudes in critical care providers and for isolating targets for additional education on donation after cardiac death.

RESUMO

OBJECTIVES: During critical illness, impaired endothelial vascular reactivity predicts prolonged acute brain dysfunction, but relationships between endothelial activation, blood-brain barrier/neurological injury, and acute brain dysfunction, including delirium, remain unexamined. We tested the hypothesis that elevated plasma markers of endothelial activation and blood-brain barrier/neurological injury are associated with delirium duration during critical illness. DESIGN: Prospective cohort study. SETTING: Medical and surgical ICUs in an academic medical center. PATIENTS: Adults in acute respiratory failure and/or shock. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We enrolled subjects within 72 hours of organ failure diagnosis in the ICU. We measured plasma concentrations of plasminogen activator inhibitor-1, E-selectin, and angiopoietin-2 as markers of endothelial activation and S100B as a marker of blood-brain barrier/neurological injury in blood collected at enrollment. We assessed patients for delirium and coma twice daily after enrollment using the Confusion Assessment Method for the ICU and the Richmond Agitation-Sedation Scale. Among 134 patients with a median (interquartile) age of 57 years (46-66 yr) and Acute Physiology and Chronic Health Evaluation II of 26 (19-31), delirium occurred in 94 patients (70%) with a median duration of 2 days (0-4 d). Higher plasminogen activator inhibitor-1 (p = 0.002), E-selectin (p = 0.02), and S100B (p < 0.001) concentrations were associated with fewer delirium/coma-free days after adjusting for age, Charlson comorbidity index, modified Sequential Organ Failure Assessment score, and severe sepsis. Similarly, higher plasminogen activator inhibitor-1 (p = 0.007) and S100B (p = 0.01) concentrations were associated with longer delirium duration in survivors. Adjusting for S100B did not alter plasminogen activator inhibitor-1 and E-selectin associations with delirium, suggesting that these associations were not mediated by blood-brain barrier/neurological injury. CONCLUSIONS: Elevated plasma markers of endothelial activation and blood-brain barrier/neurological injury during critical illness are associated with prolonged delirium after biomarker measurement. Future research is needed to determine whether these processes have pathophysiologic roles in delirium and whether therapies targeted at the endothelium or blood-brain barrier can prevent and/or treat delirium during critical illness.

RESUMO

Severe shock is a life-threatening condition with very high short-term mortality. Whether the long-term outcomes among survivors of severe shock are similar to long-term outcomes of other critical illness survivors is unknown. We therefore sought to assess long-term survival and functional outcomes among 90-day survivors of severe shock and determine whether clinical predictors were associated with outcomes. Seventy-six patients who were alive 90 days after severe shock (received ≥1 µg/kg per minute of norepinephrine equivalent) were eligible for the study. We measured 3-year survival and long-term functional outcomes using the Medical Outcomes Study 36-Item Short-Form Health Survey, the EuroQOL 5-D-3L, the Hospital Anxiety and Depression Scale, the Impact of Event Scale-Revised, and an employment instrument. We also assessed the relationship between in-hospital predictors and long-term outcomes. The mean long-term survival was 5.1 years; 82% (62 of 76) of patients survived, of whom 49 were eligible for follow-up. Patients who died were older than patients who survived. Thirty-six patients completed a telephone interview a mean of 5 years after hospital admission. The patients' Physical Functioning scores were below U.S. population norms (P < 0.001), whereas mental health scores were similar to population norms. Nineteen percent of the patients had symptoms of depression, 39% had symptoms of anxiety, and 8% had symptoms of posttraumatic stress disorder. Thirty-six percent were disabled, and 17% were working full-time. Early survivors of severe shock had a high 3-year survival rate. Patients' long-term physical and psychological outcomes were similar to those reported for cohorts of less severely ill intensive care unit survivors. Anxiety and depression were relatively common, but only a few patients had symptoms of posttraumatic stress disorder. This study supports the observation that acute illness severity does not determine long-term outcomes. Even extremely critically ill patients have similar outcomes to general intensive care unit survivor populations.

RESUMO

BACKGROUND: Critical illness is associated with cognitive impairment, but mental health and functional disabilities in survivors of intensive care are inadequately characterised. We aimed to assess associations of age and duration of delirium with mental health and functional disabilities in this group. METHODS: In this prospective, multicentre cohort study, we enrolled patients with respiratory failure or shock who were undergoing treatment in medical or surgical ICUs in Nashville, TN, USA. We obtained data for baseline demographics and in-hospital variables, and assessed survivors at 3 months and 12 months with measures of depression (Beck Depression Inventory II), post-traumatic stress disorder (PTSD, Post-Traumatic Stress Disorder Checklist-Event Specific Version), and functional disability (activities of daily living scales, Pfeffer Functional Activities Questionnaire, and Katz Activities of Daily Living Scale). We used linear and proportional odds logistic regression to assess the independent associations between age and duration of delirium with mental health and functional disabilities. This study is registered with ClinicalTrials.gov, number NCT00392795. FINDINGS: We enrolled 821 patients with a median age of 61 years (IQR 51-71), assessing 448 patients at 3 months and 382 patients at 12 months after discharge. At 3 months, 149 (37%) of 406 patients with available data reported at least mild depression, as did 116 (33%) of 347 patients at 12 months; this depression was mainly due to somatic rather than cognitive-affective symptoms. Depressive symptoms were common even among individuals without a history of depression (as reported by a proxy), occurring in 76 (30%) of 255 patients with data at 3 months and 62 (29%) of 217 individuals at 12 months. Only 7% of patients (27 of 415 at 3 months and 24 of 361 at 12 months) had symptoms consistent with post-traumatic distress disorder. Disabilities in basic activities of daily living (ADL) were present in 139 (32%) of 428 patients at 3 months and 102 (27%) of 374 at 12 months, as were disabilities in instrumental ADL in 108 (26%) of 422 individuals at 3 months and 87 (23%) of 372 at 12 months. Mental health and functional difficulties were prevalent in patients of all ages. Although old age was frequently associated with mental health problems and functional disabilities, we observed no consistent association between the presence of delirium and these outcomes. INTERPRETATION: Poor mental health and functional disability is common in patients treated in intensive-care units. Depression is five times more common than is post-traumatic distress disorder after critical illness and is driven by somatic symptoms, suggesting approaches targeting physical rather than cognitive causes could benefit patients leaving critical care.

RESUMO

BACKGROUND: Thanks to significant technical improvements, VA-ECMO is increasingly used to reverse circulatory collapse refractory to standard treatments. METHODS: We studied patients who underwent VA-ECMO due to primary cardiogenic shock or cardiac arrest between January 2008 and June 2011 at our institution. Variables related to hospital survival were analyzed. Long-term survival and health-related quality of life were checked. RESULTS: VA-ECMO was instituted in 23 patients: 17 outpatients and 6 inpatients. Seven of the outpatients were admitted to hospital under ongoing CPR. In these pts, time to CPR was 7 min (6-8) and time to ECMO 93 min (74-107); after 20 hours (16-22), all these pts died. Among remaining 16 pts, 6 were bridged to heart transplant and 4 to heart recovery, 8 survived to hospital discharge and 7 were alive with high health-related quality of life after 46 months (36-54). Ongoing CPR, inotropic score and lactates at cannulation did not differ between survivors and non-survivors; duration of shock, SOFA score and serum creatinine at ECMO institution, and lactates and fluid balance after 36 hours were higher in non-survivors. Patients could be kept on spontaneous breathing for >30% of time while on VA-ECMO. CONCLUSION: Emergency VA-ECMO institution can reverse refractory acute cardiovascular collapse, provided it is carried out before significant organ dysfunction occurs. Light sedation and spontaneous breathing while on VA-ECMO can be well tolerated by patients, but related clinical benefits should be proved. Patients successfully bridged to heart recovery or transplant are candidates for long-term good quality of life.

RESUMO

The treatment of patients in the trauma room places extraordinary demands on the multidisciplinary and multiprofessional team with regard to expert qualifications and teamwork. The present study triangulates data extracted from observation, interviews and questionnaires. In general, team climate and teamwork are good, yet some problems could be identified. Not all team members-especially younger physicians and nurses-feel free to express their doubts and uncertainties. Furthermore, the treatment plan is not always clear for all team members. Absent or unclear leadership is seen as a main problem when a treatment proceeds negatively. The establishment of a team leader is therefore recommended.

RESUMO

Estrogen has been shown to have a strong modulatory influence on several types of cognition in both women and female rodents. Latent inhibition is a task in which pre-exposure to a neutral stimulus, such as a tone, later impedes the association of that stimulus with a particular consequence, such as a shock. Previous work from our lab demonstrates that high levels of estradiol (E2) administered to ovariectomized (OVX) female rats abolishes latent inhibition when compared to female rats with low levels of E2 or male rats. To determine if this E2-induced impairment also occurs with the natural variations of ovarian hormones during the estrous cycle, this behavior was investigated in cycling female rats. In addition, pre-pubertal male and female rats were also tested in this paradigm to determine if the previously described sex differences are activational or organizational in nature. In a latent inhibition paradigm using a tone and a shock, adult rats were conditioned during different points of the estrous cycle. Rats conditioned during proestrus, a period of high E2 levels, exhibited attenuated latent inhibition when compared to rats conditioned during estrus or metestrus, periods associated with low levels of E2. Moreover, this effect is not seen until puberty indicating it is dependent on the surge of hormones at puberty. This study confirms recent findings that high E2 interferes with latent inhibition and is the first to show this is based in the activational actions of hormones.

RESUMO

UNLABELLED: Previous research indicates that exposure to shock decreases thermal pain sensitivity in humans. This hypoalgesia has been attributed to a centrally mediated fear state that activates descending inhibitory pathways. Animal research suggests that distraction alters the activation of these hypoalgesic systems. To determine whether the pain memory alters the activation of hypoalgesic systems in humans, the present study examined whether a post-shock distractor attenuates shock-induced hypoalgesia. If fear-inducing shocks are represented by a limited capacity working memory system, then a distractor should speed the decay of the hypoalgesia. Healthy men were randomly assigned to 1 of 4 groups: shock-distraction, shock-no distraction, no shock-distraction, and no shock-no distraction. Following baseline pain tests, participants in the shock groups were presented with 3 brief shocks. Immediately following shock, an unexpected vibration stimulus was presented to participants in the distraction groups. Both self-report and physiological (SCL, HR) measures indicated that shock exposure resulted in fear, arousal, and decreased pain sensitivity. Consistent with prior animal studies, presentation of a post-shock distractor sped the decay of shock-induced hypoalgesia. Specifically, the distraction group exhibited significantly less shock-induced hypoalgesia compared to the no-distraction group. These findings provide additional evidence for the involvement of memory processes in the activation of descending pain inhibitory pathways. PERSPECTIVE: This study demonstrated that the presentation of a distracting stimulus immediately following 3 brief shocks attenuated shock-induced hypoalgesia in healthy human subjects. Understanding the impact of post-pain distraction on pain processing may have important clinical implications because it may influence patients' willingness to undergo future painful medical procedures.

RESUMO

OBJECTIVES: Cold water temperature is a significant factor in North American drownings. These deaths are usually attributed to hypothermia. Survey questions were administered to 661 attendees of cold-stress seminars-including medical, rescue, law enforcement and lay attendees-to determine general knowledge of the effects of ice water immersion and responses to 2 public service educational slogans. METHODS: Five questions were posed at the beginning of seminars to 8 groups (ranging in size from 46 to 195) during a 2-year period. Pi(2) analyses were used to determine if responses within any occupational category differed from the group responses. RESULTS: A high portion of respondents greatly underestimated the time to become hypothermic in ice water (correct answer >30 minutes; 84% stated 15 minutes or less) and the time until cooling was life threatening (correct answer >60 minutes; 85% stated 30 minutes or less). There were no occupational differences in these responses. Most of the respondents identified a correct cause of death during cold stress (81% stated cardiac arrest, hypothermia, or drowning). Although both educational slogans had some advantages, between 40% (Slogan #1) to 50% (Slogan #2) of respondents did not respond correctly. CONCLUSIONS: The majority of respondents underestimated the time available for survival during ice water immersion. It is important to educate the public accurately to decrease the probability of panic under these circumstances. More work is required to develop effective educational slogans that provide proper information and actions for victims of cold-water immersion.

RESUMO

Pavlovian contextual fear conditioning occurs when an aversive unconditional stimulus (US), such as a footshock, is presented to a rat shortly after it is placed in an experimental context. Contextual fear conditioning does not occur when the shock is presented immediately upon placement of the rat in the novel chamber. In the present study, the authors report that increasing either the number of immediate shock sessions (Experiment 1) or the immediate shock duration (Experiment 2) did not reverse this deficit. However, immediate shock seems to sensitize subsequent context conditioning (Experiment 3). These findings suggest that the associative deficit produced by immediate shock is not related to the rat's ability to process the footshock US.

RESUMO

The fate of multiple trauma patients is witnessed by a considerable number of relatives. Although numerous studies report that the patient's course and treatment success are dependent on the family's confidence as well as its clarification over the clinical situation, scientifically based guidelines for contact with relatives in the context of acute care following severe traumatic injuries do not yet exist. The current guidelines of the European Resuscitation Council recommend the concept of "on scene" presence for the integration of the relatives into acute care in situations of circulatory and heart failure, thus recommending the presence of relatives during acute medical care. This article discusses this concept and argues for a possible assignment of management of trauma care for severe and gravely injured patients.

RESUMO

The article presents the conception of biological nature of torpid syndrome. The hypobiotic reaction appearing at the beginning of evolution had secured biological systems survival through all its stages in extreme circumstances of habitat. Preserved ancient hypobiosis mechanisms of human and most mammals will mobilize at once when hazardous conditions appeared to secure life and maintain vital capacity. Theoretically, it was concluded that patients with signs of torpid syndrome have life-saving protective components of an extreme reaction. Practically, in this situation we can use in a complex treatment specific hypobiotic drugs to enhance these components. We should be careful prescribing stimulants which decrease the efficacy of the hypobiotic defense.
