    Acute Respiratory Distress Syndrome (ARDS) continues to have a high mortality. Currently, there are no biomarkers that provide reliable prognostic information to guide clinical management or stratify risk among clinical trial participants. The objective of this study was to probe the bronchoalveolar lavage fluid (BALF) proteome to identify proteins that differentiate survivors from non-survivors of ARDS. Patients were divided into early-phase (1 to 7 days) and late-phase (8 to 35 days) groups based on time after initiation of mechanical ventilation for ARDS (Day 1). Isobaric tags for absolute and relative quantitation (iTRAQ) with LC MS/MS was performed on pooled BALF enriched for medium and low abundance proteins from early-phase survivors (n = 7), early-phase non-survivors (n = 8), and late-phase survivors (n = 7). Of the 724 proteins identified at a global false discovery rate of 1%, quantitative information was available for 499. In early-phase ARDS, proteins more abundant in survivors mapped to ontologies indicating a coordinated compensatory response to injury and stress. These included coagulation and fibrinolysis; immune system activation; and cation and iron homeostasis. Proteins more abundant in early-phase non-survivors participate in carbohydrate catabolism and collagen synthesis, with no activation of compensatory responses. The compensatory immune activation and ion homeostatic response seen in early-phase survivors transitioned to cell migration and actin filament based processes in late-phase survivors, revealing dynamic changes in the BALF proteome as the lung heals. Early phase proteins differentiating survivors from non-survivors are candidate biomarkers for predicting survival in ARDS. PMID:25290099

    Acute respiratory distress syndrome (ARDS) is an acute respiratory failure produced by an inflammatory edema secondary to increased lung capillary permeability. This causes alveolar flooding and subsequently deep hypoxemia, with intrapulmonary shunt as its most important underlying mechanism. Characteristically, this alteration is unresponsive to high FIO2 and only reverses with end-expiratory positive pressure (PEEP). Pulmonary infiltrates on CXR and CT are the hallmark, together with decreased lung compliance. ARDS always occurs within a week of exposition to a precipitating factor; most frequently pneumonia, shock, aspiration of gastric contents, sepsis, and trauma. In CT scan, the disease is frequently inhomogeneous, with gravitational infiltrates coexisting with normal-density areas and also with hyperaerated parenchyma. Mortality is high (30-60%) especially in ARDS associated with septic shock and neurocritical diseases. The cornerstone of therapy lies in the treatment of the underlying cause and in the use mechanical ventilation which, if inappropriately administered, can lead to ventilator-induced lung injury. Tidal volume = 6 ml/kg of ideal body weight to maintain an end-inspiratory (plateau) pressure = 30 cm H2O ("protective ventilation") is the only variable consistently associated with decreased mortality. Moderate-to-high PEEP levels are frequently required to treat hypoxemia, yet no specific level or titration strategy has improved outcomes. Recently, the use of early prone positioning in patients with PaO2/FIO2 = 150 was associated with increased survival. In severely hypoxemic patients, it may be necessary to use adjuvants of mechanical ventilation as recruitment maneuvers, pressure-controlled modes, neuromuscular blocking agents, and extracorporeal-membrane oxygenation. Fluid restriction appears beneficial. PMID:27576283

    Abstract Purpose: Studies have found disparities in psychological distress between lesbian and gay cancer survivors and their heterosexual counterparts. Exercise and partner support are shown to reduce distress. However, exercise interventions haven't been delivered to lesbian and gay survivors with support by caregivers included. Methods: In this pilot randomized controlled trial (RCT), ten lesbian and gay and twelve heterosexual survivors and their caregivers were randomized as dyads to: Arm 1, a survivor-only, 6-week, home-based, aerobic and resistance training program (EXCAP©®); or Arm 2, a dyadic version of the same exercise program involving both the survivor and caregiver. Psychological distress, partner support, and exercise adherence, were measured at baseline and post-intervention (6 weeks later). We used t-tests to examine group differences between lesbian/gay and heterosexual survivors and between those randomized to survivor-only or dyadic exercise. Results: Twenty of the twenty-two recruited survivors were retained post-intervention. At baseline, lesbian and gay survivors reported significantly higher depressive symptoms (P = .03) and fewer average steps walked (P = .01) than heterosexual survivors. Post-intervention, these disparities were reduced and we detected no significant differences between lesbian/gay and heterosexual survivors. Participation in dyadic exercise resulted in a significantly greater reduction in depressive symptoms than participation in survivor-only exercise for all survivors (P = .03). No statistically significant differences emerged when looking across arm (survivor-only vs. dyadic) by subgroup (lesbian/gay vs. heterosexual). Conclusion: Exercise may be efficacious in ameliorating disparities in psychological distress among lesbian and gay cancer survivors, and dyadic exercise may be efficacious for survivors of diverse sexual orientations. Larger trials are needed to replicate these findings. PMID:26652029

    Infants of 603 patients on whom information about smoking habits during pregnancy was available were studied for incidence respiratory distress syndrome. Among the 360 patients who did not smoke, the incidence of respiratory distress syndrome in the neonate was 15.1%, whereas among patients who smoked, the incidence was 9.1%. We speculate that smoking produces a condition of chronic stress in the fetus which brings about an acceleration of fetal pulmonary maturation. PMID:6624813

    Objective Recent studies have highlighted disparities in cancer diagnosis between lesbian, gay, bisexual and transgender (LGBT) and heterosexual adults. Studies have yet to examine disparities between LGBT and heterosexual cancer survivors in prevalence of psychological distress. Methods Data for the current study were drawn from the LIVESTRONG dataset, a US national survey that sampled 207 LGBT and 4899 heterosexual cancer survivors (all cancer types, 63.5% women, mean age 49) in 2010. Symptoms of psychological distress were assessed with dichotomous yes/no items in three symptom clusters (depression related to cancer, difficulties with social relationships post-cancer, fatigue/energy problems). We selected a sample of 621 heterosexual survivors matched by propensity score to the 207 LGBT survivors and assessed disparities in count of symptoms using Poisson regression. We also performed subgroup analyses by self-reported sex. Results Relative to heterosexuals, LGBT cancer survivors reported a higher number of depression and relationship difficulty symptoms. Exploratory analyses revealed that disparities in number of symptoms were visible between gay, bisexual, and transgender versus heterosexual men but not between lesbian, bisexual, and transgender versus heterosexual women. Conclusions This study highlights several disparities in psychological distress that exist between LGBT and heterosexual survivors. A need remains for interventions tailored to LGBT survivors and for studies examining disparities within subgroups of LGBT survivors. PMID:25630987

    The acute respiratory distress syndrome (ARDS) was defined in 1994 by the American-European Consensus Conference (AECC); since then, issues regarding the reliability and validity of this definition have emerged. Using a consensus process, a panel of experts convened in 2011 (an initiative of the European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine) developed the Berlin Definition, focusing on feasibility, reliability, validity, and objective evaluation of its performance. A draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (200 mm Hg < PaO2/FIO2 ≤ 300 mm Hg), moderate (100 mm Hg < PaO2/FIO2 ≤ 200 mm Hg), and severe (PaO2/FIO2 ≤ 100 mm Hg) and 4 ancillary variables for severe ARDS: radiographic severity, respiratory system compliance (≤40 mL/cm H2O), positive end-expiratory pressure (≥10 cm H2O), and corrected expired volume per minute (≥10 L/min). The draft Berlin Definition was empirically evaluated using patient-level meta-analysis of 4188 patients with ARDS from 4 multicenter clinical data sets and 269 patients with ARDS from 3 single-center data sets containing physiologic information. The 4 ancillary variables did not contribute to the predictive validity of severe ARDS for mortality and were removed from the definition. Using the Berlin Definition, stages of mild, moderate, and severe ARDS were associated with increased mortality (27%; 95% CI, 24%-30%; 32%; 95% CI, 29%-34%; and 45%; 95% CI, 42%-48%, respectively; P < .001) and increased median duration of mechanical ventilation in survivors (5 days; interquartile [IQR], 2-11; 7 days; IQR, 4-14; and 9 days; IQR, 5-17, respectively; P < .001). Compared with the AECC definition, the final Berlin Definition had better predictive validity for mortality, with an area under the receiver operating curve of 0.577 (95% CI, 0.561-0.593) vs 0.536 (95% CI, 0.520-0.553; P

    Objective Lymphedema is a distressing and chronic condition affecting up to 30% of breast cancer survivors. Using a cross-sectional study design, we examined the impact of self-reported lymphedema-related distress on psychosocial functioning among breast cancer survivors in the Women’s Healthy Eating and Living (WHEL) Study. The WHEL Study has a dataset that includes self-report data on lymphedema status, symptoms and distress. Methods Chi-square tests and binary logistic regression models were used to examine how specific participant characteristics, including lymphedema-related distress, were associated with physical health and mental health as measured by the SF-36 and depressive symptoms assessed by the CES-Dsf. Results Of the 2,431 participants included in the current study population, 692 (28.5%) self-reported ever having lymphedema. A total of 335 (48.9%) women reported moderate to extreme distress as a result of their lymphedema and were classified as having lymphedema-related distress. The logistic regression models showed that women with lymphedema-related distress had 50% higher odds of reporting poor physical health (p=0.01) and 73% higher odds of having poor mental health (p<0.01) when compared to women without lymphedema. In contrast, even though lymphedema-related distress was significantly associated (p=0.03) with elevated depressive symptoms in the bivariate analyses, it was not significant in the logistic regression models. Conclusion Breast cancer survivors with lymphedema-related distress had worse physical and mental health outcomes than women with lymphedema who were not distressed and women with no lymphedema. Our findings provide further evidence of the relationship between lymphedema and psychosocial outcomes in breast cancer survivors. PMID:24615880

    Many disaster survivors suffer from postdisaster distress regardless of whether or not they meet criteria for specific psychiatric diagnoses. Cognitive Behavior Therapy for Postdisaster Distress (CBT-PD), a ten-session manualized intervention, was developed to address a range of cognitive, emotional, and behavioral reactions to disaster. Trained community-based therapists provided CBT-PD to adult survivors of Hurricane Katrina as part of InCourage, a program sponsored by the Baton Rouge Area Foundation. Participants (n = 88) who were assessed at referral, pretreatment, intermediate treatment, and posttreatment showed significant and large improvements. The overall pre-post effect size was 1.4 in intention-to-treat analyses. Improvements were comparable for persons with more severe distress and persons with moderate distress at referral. Benefits were maintained at follow-up for the 66 adults who have been assessed.

    This article describes the gas exchange abnormalities occurring in the acute respiratory distress syndrome seen in adults and children and in the respiratory distress syndrome that occurs in neonates. Evidence is presented indicating that the major gas exchange abnormality accounting for the hypoxemia in both conditions is shunt, and that approximately 50% of patients also have lungs regions in which low ventilation-to-perfusion ratios contribute to the venous admixture. The various mechanisms by which hypercarbia may develop and by which positive end-expiratory pressure improves gas exchange are reviewed, as are the effects of vascular tone and airway narrowing. The mechanisms by which surfactant abnormalities occur in the two conditions are described, as are the histological findings that have been associated with shunt and low ventilation-to-perfusion.

    Blood lactate was measured 4-hourly in 21 newborn babies with respiratory distress syndrome, of whom 13 survived and 8 died. In general, lactate levels were higher in babies who died than in survivors, but there were inconsistencies which were uninterpretable if only a single estimation were made in a baby. Analysis of serial determinations showed that all patients in whom the lactate level never exceeded 35 mg/100 ml survived, and babies with high but falling values also did well. Only those who had rising lactate values, even if initially normal, died. In most cases a high or normal Pao2 was associated with normal or decreasing lactate level; but babies with Pao2 below 60 mmHg had often also normal or decreasing lactate levels. Some babies had high and increasing lactate levels despite having normal Pao2. In order to use lactate levels for prognosis in respiratory distress syndrome (RDS) serial determinations are required. It is concluded that there may be a wide range of hypoxaemia without oxygen deficit in body tissues, so that it is not possible to define a `lower acceptable Pao2' which will define adequate tissue oxygenation.

    2016-01-01

    Despite distinct epidemiology and outcomes, pediatric acute respiratory distress syndrome (PARDS) is often managed based on evidence extrapolated from treatment of adults. The impact of non-pulmonary processes on mortality as well as the lower mortality rate compared to adults with acute respiratory distress syndrome (ARDS) renders the utilization of short-term mortality as a primary outcome measure for interventional studies problematic. However, data regarding alternatives to mortality are profoundly understudied, and proposed alternatives, such as ventilator-free days, may be themselves subject to hidden biases. Given the neuropsychiatric and functional impairment in adult survivors of ARDS, characterization of these morbidities in children with PARDS is of paramount importance. The purpose of this review is to frame these challenges in the context of the existing pediatric literature, and using adult ARDS as a guide, suggest potential clinically relevant outcomes that deserve further investigation. The goal is to identify important areas of study in order to better define clinical practice and facilitate future interventional trials in PARDS. PMID:27242980

    The prevalence of psychological distress is higher in cancers with poorer prognoses and speculated as higher in those receiving more aversive treatments. Since hematopoietic stem cell transplant (HSCT) is one of the most taxing cancer treatments to endure and is therefore likely to have more long-term sequelae, this study examined psychological distress symptoms in long-term HSCT survivors who were at least 1 year post-transplant. Participants in this cross-sectional study were recruited from urban medical centers as part of a larger study of HSCT survivors. The sample comprised 236 adults who were on average 3.4 years since transplant. Psychological distress was measured by a commonly used self-report questionnaire, the Brief Symptom Inventory. Clinically elevated psychological distress caseness was present in 43% of long-term HSCT survivors. Elevations were highest on clinical subscales of obsessive-compulsiveness, somatization, and psychoticism. However, item-level analyses revealed that the content of the most frequently reported symptoms included trouble with memory and feelings of loneliness. Results of this study suggest that HSCT survivors may experience memory and existential concerns and that such symptoms may not represent psychiatric sequelae.

    The Emotional Security Theory (EST) was originally developed to investigate the association between high levels of interparental conflict and child maladaptative outcome. The objective of the present study was to analyze the effects of emotional security in the family system on psychological distress among a sample of young female adult survivors of child sexual abuse (CSA). The role of emotional security was investigated through the interactive effects of a number of factors including the type of abuse, the continuity of abuse, the relationship with the perpetrator and the existence of disclosure for the abuse. Participants were 167 female survivors of CSA. Information about the abuse was obtained from a self-reported questionnaire. Emotional security was assessed with the Security in the Family System (SIFS) Scale, and the Symptom Checklist-90-Revised (SCL-90-R) was used to assess psychological distress. In the total sample, insecurity (preoccupation and disengagement) was correlated with high psychological distress scores, whereas no relationship was found between security and psychological distress. The relationship between emotional insecurity and psychological distress was stronger in cases of continued abuse and non-disclosure, while the relationship between emotional security and distress was stronger in cases of extrafamilial abuse and especially isolated or several incidents and when a disclosure had been made. No interactive effect was found between any of the three emotional variables and the type of abuse committed. The results of the current study suggest that characteristics of CSA such as relationship with the perpetrator and, especially, continuity of abuse and whether or not disclosure had been made, can affect the impact of emotional security on psychological distress of CSA survivors.

    OBJECTIVE To evaluate associations between prepregnancy lifestyle factors, psychological distress and adverse pregnancy outcomes among female survivors of childhood cancer. STUDY DESIGN We examined pregnancies of 1,192 female participants from the Childhood Cancer Survivor Study. Generalized linear models, adjusted for age at diagnosis, age at pregnancy, parity, and education were used to calculate the odds ratio (OR) and confidence interval (CI) for associations between prepregnancy inactivity, overweight or obese status, smoking status, risky drinking, psychological distress and pregnancy outcomes. Interactions between lifestyle factors, psychological distress, type of cancer and cancer treatment were assessed in multivariable models. RESULTS The median age of study participants at the beginning of pregnancy was 28 years (range: 14–45). Among 1,858 reported pregnancies, there were 1,300 singleton live births (310 were preterm), 21 stillbirths, 397 miscarriages, and 140 medical abortions. Prepregnancy physical inactivity, risky drinking, distress and depression were not associated with any pregnancy outcomes. Compared to those who had never smoked, survivors with > 5 pack-years smoking history had a higher risk for miscarriage among those treated with > 2.5 Gy uterine radiation (OR: 53.9; 95% CI: 2.2, 1,326.1) than among those treated with ≤ 2.5 Gy uterine radiation (OR: 1.9; 95% CI: 1.2, 3.0). There was a significant interaction between smoking and uterine radiation (Pinteraction = 0.01). CONCLUSION While most lifestyle factors and psychological distress were not predictive of adverse pregnancy outcomes, the risk for miscarriage was significantly increased among survivors exposed to > 2.5 Gy uterine radiation who had a history of smoking.

    Context: Lack of literature on psychological aspects of survivors of farmers' suicides is hurdle in devising effective helping strategies for rising number of survivors across the country. Aims and Objectives: To assess the psychological distress and its correlates in survivors of farmers' suicides. Settings and Design: Case–control study design was used in Wardha District of Vidarbha region in the central India. Materials and Methods: A predesigned and pretested semistructured questionnaire was used to assess sociodemographic variables. Self-Reporting Questionnaire-20 was used to evaluate psychological distress in 98 survivors of farmers' suicides and 98 age, sex, and occupation-matched controls. Statistical Analysis: Significance of differences between case and control groups were assessed using Chi-square test or Fisher's two-tailed exact test for class variables. For continuous variables, Student's t-test was used P < 0.05 was considered significant. Results: Significantly higher proportion of survivors had psychological distress than controls. Female survivors, spouse and parents of suicide victims had a high risk of distress. Psychological distress was commonly expressed by depressive and somatic symptoms. Conclusions: Survivors of farmers' suicides are suffering from significant psychological distress. PMID:27385846

    Leventhal's common sense model has provided a useful framework for explaining psychological distress in several chronic illnesses. The model indicates that a person's perception of their illness and their coping strategies are the key determinants of their experience of psychological distress. The present research examines whether illness perceptions and coping strategies are related to levels of psychological distress among survivors of esophageal cancer. Everyone registered with the Oesophageal Patients' Association in the UK was mailed a questionnaire booklet, which included the Illness Perception Questionnaire-Revised, the Cancer Coping Questionnaire, and the Hospital Anxiety and Depression Scale. Complete responses were received from 484 people. Regression models indicated that the variables measured could explain 51% of the variance in anxiety and 42% of the variance in depression. Perceptions of esophageal cancer explained the majority of this variance. Positive focus coping strategies were also found to be important in explaining psychological distress. The results of this study are consistent with previous research demonstrating that illness perceptions are stronger correlates of adaptive outcomes than coping strategies. The findings suggest that cognition-based interventions could potentially be most effective in minimizing emotional distress among survivors of esophageal cancer.

    OBJECTIVE—To determine prospectively the efficacy of surfactant in acute respiratory distress syndrome.
STUDY DESIGN—Twenty patients, 1 month to 16 years of age, diagnosed with an acute pulmonary disease with severe hypoxaemia (PaO2/FiO2 < 100) (13 with systemic or pulmonary disease and seven with cardiac disease) were treated with one to six doses of 50-200 mg/kg of porcine surfactant administered directly into the trachea. The surfactant was considered to be effective when the PaO2/FiO2 improved by > 20%.
RESULTS—After initial surfactant administration the PaO2/FiO2 increased significantly in patients with systemic or pulmonary disease from 68 to 111, and the oxygenation index (OI) diminished significantly from 36.9 to 27.1. The PaO2/FiO2 and OI did not improve in children with cardiac disease. The improvement of the patients who survived was greater than that of those who died.
CONCLUSIONS—Surfactant moderately improves oxygenation in some children with severe acute respiratory distress syndrome secondary to pulmonary or systemic disease.

    Acute respiratory distress syndrome is characterized by a diffuse inflammatory reaction of lung parenchyma induced by a direct insult to the alveolar epithelium (pulmonary acute respiratory distress syndrome) or an indirect lesion through the vascular endothelium (extrapulmonary acute respiratory distress syndrome). The main therapeutic strategy for acute respiratory distress syndrome is the ventilatory support. However, mechanical ventilation can worsen lung injury. In this context, a protective ventilatory strategy with low tidal volume has been proposed. The use of low tidal volume reduced the mortality rate of acute respiratory distress syndrome patients, but result in hypercapnic acidosis. The current article presents a review of literature on the effects of permissive hypercapnia in acute respiratory distress syndrome. To that end, we carried out a systematic review of scientific literature based on established criteria for documental analysis including clinical and experimental articles, using as data bases MedLine, LILACS, SciELO, PubMed, Cochrane. Hypercapnic acidosis has been considered by some authors as a modulator of the inflammatory process of acute respiratory distress syndrome. However, clinical and experimental studies on the effects of hypercapnic acidosis have shown controversial results. Therefore it is important to better elucidate the role of hypercapnic acidosis in acute respiratory distress syndrome.

    Disaster mental health research has historically focused on assessment of psychopathology, using measures of psychiatric symptoms and disorders. The Oakland/Berkeley firestorm provided an opportunity to explore resilience among highly exposed survivors through consideration of psychiatric variables in the context of personality. The Diagnostic Interview Schedule/Disaster Supplement was administered to 62 firestorm survivors at approximately 4, 16, and 39 months and the Temperament and Character Inventory administered at 16 months postdisaster. Few individuals had postdisaster psychopathology (16% with any diagnosis, 5%with PTSD). There was considerable evidence of distress, however, indicated by an abundance of reported posttraumatic symptoms, functional impairments, and endorsement of emotional upset, all of which decreased substantially over time. Group C (avoidance/numbing) posttraumatic symptoms were relatively uncommon and were specifically associated with elevated Self-Transcendence. Groups B (intrusion) and D (hyperarousal) symptoms were prevalent and were associated with high Harm Avoidance and low Self-Directedness. The generally healthy personality profiles of these firestorm survivors reflected their psychological resilience. Examination of symptoms and distress in the context of psychiatric disorders after this disaster demonstrated that symptomatic distress is not inconsistent with psychological resilience. The choice of research focus and methods can provide very different portraits of outcomes post-disaster. PMID:18377204

    Predictors of emotional distress, general health, and stroke-related caregiving outcomes were determined in 104 family caregivers of stroke survivors based on a conceptual model derived from Lazarus' theory of stress and coping. Predictors of emotional distress (R(2) =.48, p <.001) were low caregiver self-esteem, high task difficulty, and high threat appraisal. Predictors of poorer health (R(2) =.25, p <.001) were not living with the patient, low household income, and high threat appraisal. Predictors of poor stroke-related care-giving outcomes (R(2) =.45, p <.001) were emotional distress, low benefit appraisal, high task difficulty, and high threat appraisal. Findings suggest potential areas for multidimensional caregiver interventions.

    Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome reflects a serious hypersensitivity reaction to drugs, and is characterized by skin rash, fever, lymph node enlargement, and internal organ involvement. So far, numerous drugs such as sulfonamides, phenobarbital, sulfasalazine, carbamazepine, and phenytoin have been reported to cause DRESS syndrome. We report a case of a 10-year-old girl who developed clinical manifestations of fever, rash, lymphadenopathy, hypereosinophilia, and visceral involvement (hepatitis and pneumonitis) after taking phenobarbital for seizures, with subsequent development of sepsis, acute respiratory distress syndrome (ARDS) and spontaneous air leak syndrome (pnemothorax and pneumomediastinum). She was put on steroids and various antibiotics and was ventilated, but ultimately succumbed to sepsis and pulmonary complications. PMID:22345792

    The acute respiratory distress syndrome (ARDS) is currently one of the most important critical entities given its high incidence, rate of mortality, long-term sequelae and non-specific pharmacological treatment. The histological hallmark of ARDS is diffuse alveolar damage (DAD). Approximately 50% of ARDS patients present DAD, the rest is made up of a heterogeneous group of histological patterns, many of which correspond to a well-recognized disease. For that reason, if these patterns could be diagnosed, patients could benefit from a treatment. Recently, the effect of DAD in clinical and analytical evolution of ARDS has been demonstrated, so the classical approach to ARDS as an entity defined solely by clinical, radiological and gasometrical variables should be reconsidered. This narrative review aims to examine the need to evolve from the concept of ARDS as a syndrome to ARDS as a specific disease. So we have raised 4 critical questions: a) What is a disease?; b) what is DAD?; c) how is DAD considered according to ARDS definition?, and d) what is the relationship between ARDS and DAD?

    Two hundred ninety-seven patients from the placebo group of the National Institutes of Health Collaborative Study on Antenatal Steroid Therapy for prevention of respiratory distress syndrome were selected for analysis to investigate a possible association between premature rupture of the membranes, tocolytic therapy, and respiratory distress syndrome. Both premature rupture of the membranes and tocolytic therapy with isoxsuprine were individually associated with a lowered incidence of respiratory distress syndrome. However, when present together, their protective effect was not additive and resulted in a higher incidence of respiratory distress syndrome. It is suggested that the use of tocolytic therapy with beta-adrenergic agents be restricted to patients with intact membranes. PMID:6695972

    Knowing one's identity, name, and biological parents is considered essential to personality development and psychological well-being. This study assessed post-traumatic stress disorder (PTSD) symptoms, subjective quality of life (QoL), psychological distress, and potency in a group of adults who were children during the Holocaust (child Holocaust survivors) and who did not know their true identity. Twenty-three such survivors were compared to 23 child Holocaust survivors who knew their identity. Results showed that survivors with lost identity had lower physical, psychological, and social QoL and higher somatization, depression, and anxiety scores than did survivors with known identity. The findings suggest that the psychological consequences of not knowing one's identity are long-lasting.

    Clinical and basic experimental approaches to pediatric acute lung injury (ALI), including acute respiratory distress syndrome (ARDS), have historically focused on acute care and management of the patient. Additional efforts have focused on the etiology of pediatric ALI and ARDS, clinically defined as diffuse, bilateral diseases of the lung that compromise function leading to severe hypoxemia within 7 days of defined insult. Insults can include ancillary events related to prematurity, can follow trauma and/or transfusion, or can present as sequelae of pulmonary infections and cardiovascular disease and/or injury. Pediatric ALI/ARDS remains one of the leading causes of infant and childhood morbidity and mortality, particularly in the developing world. Though incidence is relatively low, ranging from 2.9 to 9.5 cases/100,000 patients/year, mortality remains high, approaching 35% in some studies. However, this is a significant decrease from the historical mortality rate of over 50%. Several decades of advances in acute management and treatment, as well as better understanding of approaches to ventilation, oxygenation, and surfactant regulation have contributed to improvements in patient recovery. As such, there is a burgeoning interest in the long-term impact of pediatric ALI/ARDS. Chronic pulmonary deficiencies in survivors appear to be caused by inappropriate injury repair, with fibrosis and predisposition to emphysema arising as irreversible secondary events that can severely compromise pulmonary development and function, as well as the overall health of the patient. In this chapter, the long-term effectiveness of current treatments will be examined, as will the potential efficacy of novel, acute, and long-term therapies that support repair and delay or even impede the onset of secondary events, including fibrosis.

    Indices of thyroid function were measured in 97 preterm infants at birth and at 5, 10, and 15 days of age. Triiodothyronine uptake, free thyroxine index, thyroxine, free thyroxine, triiodothyronine, reverse triiodothyronine, and thyroxine binding globulin values at birth correlated with gestational age, whereas thyroid stimulating hormone values did not. Treatment with steroids prenatally had no apparent effect on thyroid function at birth or postnatally. Infants developing respiratory distress syndrome had normal values for all indices at birth. These infants had significantly lower thyroxine, free thyroxine index, free thyroxine, and triiodothyronine values at 5 days of age, while thyroid stimulating hormone values remained normal. This alteration in thyroid function was interpreted as being secondary to respiratory distress syndrome. Gestational maturity and respiratory distress syndrome, if present, must be taken into account when evaluating thyroxine variables in preterm infants, whereas measurement of thyroid stimulating hormone as the screen for congenital hypothyroidism circumvents these considerations.

    2011-01-01

    Background The Internet can increase access to psychosocial care for breast cancer survivors through online support groups. This study will test a novel prosocial online group that emphasizes both opportunities for getting and giving help. Based on the helper therapy principle, it is hypothesized that the addition of structured helping opportunities and coaching on how to help others online will increase the psychological benefits of a standard online group. Methods/Design A two-armed randomized controlled trial with pretest and posttest. Non-metastatic breast cancer survivors with elevated psychological distress will be randomized to either a standard facilitated online group or to a prosocial facilitated online group, which combines online exchanges of support with structured helping opportunities (blogging, breast cancer outreach) and coaching on how best to give support to others. Validated and reliable measures will be administered to women approximately one month before and after the interventions. Self-esteem, positive affect, and sense of belonging will be tested as potential mediators of the primary outcomes of depressive/anxious symptoms and sense of purpose in life. Discussion This study will test an innovative approach to maximizing the psychological benefits of cancer online support groups. The theory-based prosocial online support group intervention model is sustainable, because it can be implemented by private non-profit or other organizations, such as cancer centers, which mostly offer face-to-face support groups with limited patient reach.

    Gay men have been found to have higher rates of cancer diagnoses than heterosexual men and poorer outcomes postcancer diagnosis. The two aims of this study were to examine rates of cancer diagnosis in a national sample of gay and heterosexual men, and to examine disparities in health risk behavior between gay and heterosexual men and gay and heterosexual cancer survivors. The current study utilized data from a total sample of 14,354 men, including 373 gay men, collected as part of the Behavioral Risk Factor Surveillance System survey conducted in 2009 in the states of Arizona, California, Massachusetts, Ohio, and Wisconsin. This study replicated the finding that prevalence of self-reported cancer diagnoses differed significantly between gay and heterosexual men, with gay men 82% more likely to report a lifetime history of cancer diagnosis (p<0.05); however, this disparity became nonsignificant after controlling for a weakened immune system proxy variable (p=0.06). Gay men were more likely than heterosexual men to report health risk behaviors, including less time spent exercising, more psychological distress, more current alcohol use, more current smoking, and a lifetime history of smoking. Some of these disparities in health risk behavior persisted for gay cancer survivors postcancer diagnosis. This study offers a perspective on behavioral risk factors previously shown to be higher among gay men that may continue postcancer diagnosis. Future research should test the degree to which these disparities are caused by minority stress, as previous studies have indicated that increased health risk behaviors among sexual minority populations may result from exposure to chronic stress and discrimination. Developing behavior change interventions to address these risk behaviors is vital for improving cancer outcomes among gay men. PMID:26789618

    A significant number of long-term complications have been described in childhood leukemia survivors. In particular, these patients may present features of metabolic syndrome (MetS), and therefore increased risk for cardiovascular diseases. The aim of this meta-analysis is to evaluate the prevalence and the risk of MetS in survivors of childhood leukemia. Two authors independently performed a systematic literature search in PubMed and EMBASE to March 2014, reviewed and selected articles, based on pre-determined selection criteria. Twelve articles, comprising 2,337 participants (1,462 cases and 875 controls), were included in the meta-analysis. Only three of them were case-control studies eligible for the meta-analysis. The childhood leukemia survivors showed an increased risk of MetS as compared to healthy controls (OR = 4.36; 95 % CI 1.19-16.22). The risk was significantly increased only in patients treated with chemotherapy and radiotherapy (OR = 7.79; 95 % CI 1.27-47.77), and not in patients treated with only chemotherapy (OR = 2.35; 95 % CI 0.40-13.78). Childhood leukemia survivors, in particular if treated also with radiotherapy, are prone to develop MetS more than healthy controls. Monitoring of MetS components in these patients is necessary to avoid cardiovascular consequences later in life.

  12. Clinical review: Acute respiratory distress syndrome - clinical ventilator management and adjunct therapy

    PubMed Central

    2013-01-01

    Acute respiratory distress syndrome (ARDS) is a potentially devastating form of acute inflammatory lung injury with a high short-term mortality rate and significant long-term consequences among survivors. Supportive care, principally with mechanical ventilation, remains the cornerstone of therapy - although the goals of this support have changed in recent years - from maintaining normal physiological parameters to avoiding ventilator-induced lung injury while providing adequate gas exchange. In this article we discuss the current evidence base for ventilatory support and adjunctive therapies in patients with ARDS. Key components of such a strategy include avoiding lung overdistension by limiting tidal volumes and airway pressures, and the use of positive end-expiratory pressure with or without lung recruitment manoeuvres in patients with severe ARDS. Adjunctive therapies discussed include pharmacologic techniques (for example, vasodilators, diuretics, neuromuscular blockade) and nonpharmacologic techniques (for example, prone position, alternative modes of ventilation).

  13. Estimation of dead space fraction can be simplified in the acute respiratory distress syndrome

    PubMed Central

    2010-01-01

    Acute lung injury and acute respiratory distress syndrome are characterized by a non-cardiogenic pulmonary edema responsible for a significant impairment of gas exchange. The pulmonary dead space increase, which is due primarily to an alteration in pulmonary blood flow distribution, is largely responsible for carbon dioxide retention. Previous studies, computing the pulmonary dead space by measuring the expired carbon dioxide and the Enghoff equation, found that the dead space fraction was significantly higher in the non-survivors; it was even an independent risk of death. The computation of the dead space not by measuring the expired carbon dioxide but by applying a rearranged alveolar gas equation that takes into account only the weight, age, height, and temperature of the patient could lead to widespread clinical diffusion of this measurement at the bedside.

    The adult respiratory distress syndrome (ARDS) is seen with increasing frequency. It is associated with a variety of conditions even in the absence of preexisting pulmonary diseases. The treatment often includes intubation, using positive-end expiratory pressure (PEEP), and other ancillary support. The mortality rate is high, and physicians caring for such patients should be on guard for disseminated intravascular coagulation, gastrointestinal hemorrhage, and infection. PMID:7120452

    Lambs suffering from Acute Respiratory Distress Syndrome (ARDS) showed elevated PCV, neutrophilia, a tendency towards lymphopenia, eosinopenia, hyperphosphatemia, hypoglycemia and extremely low serum Ca values during the first couple of days after the outbreak of symptoms. During the very early phase, plasma potassium values were mostly lowered (Figs. 1-3, Table I). The possible involvement of histamine is shortly discussed: either 1) through an atopic reaction, 2) because of acute ruminal acidosis and sudden histamine formation, or 3) involvement of endotoxins.

    Social resources can buffer against psychological distress following potentially traumatic events. Psychological distress can also lead to social resource deterioration. This longitudinal study evaluated whether baseline psychological distress symptoms and changes in these symptoms were associated with changes in social resources 5 months later among 96 adult male (52.6%) and female treatment-seeking torture survivors residing in Kurdistan, Iraq. Adapted versions of the Hopkins Symptom Checklist-25, Harvard Trauma Questionnaire, and a traumatic grief measure were used. Locally derived scales measured perceived social support, social integration, and frequency of social contact. Multinomial logistic regression models assessed the association between symptoms and loss or gain in social resources. We hypothesized that higher mental health symptoms would relate to decreased social resources. Higher baseline depression (adjusted conditional odds ratio [ACOR] = 1.14), posttraumatic stress disorder (PTSD; ACOR = 1.09), and traumatic grief symptoms (ACOR = 1.14) increased the odds of loss of social integration. For some, higher traumatic grief symptoms were associated with increased social integration (ACOR = 1.17). Increased anxiety (ACOR = 1.23) and PTSD symptoms (ACOR = 1.07) was associated with declines in social contact; decreased depression (ACOR = 1.06) and PTSD symptoms (ACOR = 1.04) were related to gaining social contact. This study highlights the complex relationship between mental health symptoms and losses and gains in social resources among torture survivors.

    Because the incidence of both neonatal respiratory distress syndrome and neonatal mortality can be reduced by giving corticosteroids to women expected to deliver preterm and by giving surfactant to babies at high risk of developing hyaline membrane disease, we have considered what effects the adoption of one or both of these preventive policies would have on the costs of neonatal care. We have estimated the effects of treatment from overviews of the relevant controlled trials, and estimated costs from observations of care at one neonatal unit. Our results suggest that if either of these policies is adopted for all babies under 35 weeks' gestation at a drug cost of 150 pounds or less/baby, the overall costs of care would be reduced by between 1 and 10%. The cost per survivor would be reduced by up to 16% even if the drug cost were to be as high as pounds 550/baby. If the policies were to be adopted only for babies under 31 weeks' gestation, both policies would result in a reduction in cost of between 5 and 16%/survivor, although the increased survival resulting from the policies would lead to an increase in overall costs for babies of less then 31 weeks' gestation of between 7 and 32%.

    Severe sepsis or septic shock is characterized by an excessive inflammatory response to infectious pathogens. Acute respiratory distress syndrome (ARDS) is a devastating complication of severe sepsis, from which patients have high mortality. Advances in treatment modalities including lung protective ventilation, prone positioning, use of neuromuscular blockade, and extracorporeal membrane oxygenation, have improved the outcome over recent decades, nevertheless, the mortality rate still remains high. Timely treatment of underlying sepsis and early identification of patients at risk of ARDS can help to decrease its development. In addition, further studies are needed regarding pathogenesis and novel therapies in order to show promising future treatments of sepsis-induced ARDS. PMID:27066082

    The acute respiratory distress syndrome (ARDS) is a form of severe hypoxemic respiratory failure that is characterized by inflammatory injury to the alveolar capillary barrier, with extravasation of protein-rich edema fluid into the airspace. Although many modalities to treat ARDS have been investigated over the past several decades, supportive therapies remain the mainstay of treatment. In this article, we briefly review the definition, epidemiology, and pathophysiology of ARDS and present emerging aspects of ARDS pathophysiology that encompass modulators of the innate immune response, damage signals, and aberrant proteolysis that may serve as a foundation for future therapeutic targets.

    Since its original description in 1967, acute respiratory distress syndrome (ARDS) has been recognized as a devastating condition associated with significant morbidity and mortality. Advances in critical care medicine and ARDS management have led to a substantial increase in the number of ARDS survivors. Long-term cognitive impairment after critical illness is a significant public health concern. ARDS survivors frequently experience long-term cognitive impairment, as well as physical impairment, psychiatric morbidity, and reduced health-related quality of life. At present, no intensive care unit–based intervention has been proven to reduce the risk of long-term cognitive impairment after ARDS. To address the urgent need to identify strategies to preserve long-term health, investigators have advocated the measurement of short- and long-term outcomes in clinical trials. Maintaining adequate oxygen delivery to preserve organ function is of vital importance in ARDS management. The optimal target range for arterial oxygenation in ARDS remains unknown, due in part to the challenge to maintain adequate tissue oxygenation and to minimize harm, such as oxygen toxicity. An approach targeted to subnormal oxygenation values (partial pressure of arterial oxygen, 55–80 mm Hg) has emerged as a means to accomplish these aims. In this perspective, we critically evaluate this strategy from short- and long-term perspectives, with a focus on the potential long-term cognitive effects of the strategy. We conclude with a proposal to consider resetting the target range for arterial oxygenation higher (85–110 mm Hg) as a potential strategy to improve the long-term outcomes of ARDS survivors.

    Abstract Right ventricular (RV) dysfunction in acute respiratory distress syndrome (ARDS) contributes to increased mortality. Our aim is to identify reproducible transthoracic echocardiography (TTE) parameters of RV dysfunction that can be used to predict outcomes in ARDS. We performed a retrospective single-center cohort pilot study measuring tricuspid annular plane systolic excursion (TAPSE), Tei index, RV-fractional area change (RV-FAC), pulmonary artery systolic pressure (PASP), and septal shift, reevaluated by an independent blinded cardiologist (JK). Thirty-eight patients were included. Patients were divided on the basis of 30-day survival. Thirty-day mortality was 47%. Survivors were younger than nonsurvivors. Survivors had a higher pH, PaO2∶FiO2 ratio, and TAPSE. Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II), and Sequential Organ Failure Assessment (SOFA) scores were lower in survivors. TAPSE has the strongest association with increased 30-day mortality from date of TTE. Accordingly, TAPSE has a strong positive correlation with PaO2∶FiO2 ratios, and Tei index has a strong negative correlation with PaO2∶FiO2 ratios. Septal shift was associated with lower PaO2∶FiO2 ratios. Decrease in TAPSE, increase in Tei index, and septal shift were seen in the severe ARDS group. In multivariate logistic regression models, TAPSE maintained a significant association with mortality independent of age, pH, PaO2∶FiO2 ratios, positive end expiratory pressure, PCO2, serum bicarbonate, plateau pressures, driving pressures, APACHE II, SAPS II, and SOFA scores. In conclusion, TAPSE and other TTE parameters should be used as novel predictive indicators for RV dysfunction in ARDS. These parameters can be used as surrogate noninvasive RV hemodynamic measurements to be manipulated to improve mortality in patients with ARDS and contributory RV dysfunction. PMID:27252840

    Alcohol has been considered an important risk factor for the development of pneumonia since the last century. Nevertheless, it was not thought that it had relevant effects on lung structure and functions until recently. Recent studies have shown that the risk for acute respiratory distress syndrome (ARDS) is 2-4 times higher among alcoholic patients with sepsis or trauma, and that alcoholism can play a roll in more than 50% of cases in the pathogenesis of this syndrome. Although alcoholism per se does not cause acute lung injury it predisposes to pulmonary dysfunction after inflammatory stress, that is present in clinical situations that cause ARDS leading to its development and complicating its outcome. Recent investigations in animals and humans with alcohol abuse have uncovered several alterations currently known as the "alcoholic lung". This revision discusses the association between alcohol abuse and lung injury/ARDS and tries to explain the physiopathology along with possible treatments.

    The stability of post-traumatic growth over time and the relationship between post-traumatic growth and traditional distress outcomes remains unclear. We tracked post-traumatic growth in a population-based sample of colorectal cancer patients from soon after diagnosis to five years subsequently to assess the heterogeneity of a post-traumatic growth response to cancer over time and describe the simultaneous and longitudinal relationships between post-traumatic growth and psychological distress. 1966 colorectal patients who were five months post diagnosis were assessed six times over a five year period. There was considerable heterogeneity associated with both psychological distress and benefit finding scores over time. However, both for benefit finding and psychological distress, the variation in individual scores suggested an underlying positive linear trend and both lagged and lagged change components. Specifically, benefit finding and psychological distress are mutual leading indicators of each other. First, benefit finding served as a leading indicator of distress, in that increases in reported benefit finding from year to year predicted higher future increases in psychological distress. As well, in an inverse relationship, psychological distress served as a leading indicator of benefit finding, such that increases in reported distress from year to year predicted lower future increases in benefit finding. Post-traumatic growth may reflect patients coping efforts to enhance perceptions of wellbeing in response to escalating cancer-related threats, acting as harbinger of increasing trajectories of psychological distress. This explanation is consistent with a cognitive dissonance response in which threats to the integrity of the self then lead to a tendency to accentuate positive aspects of the self. PMID:26418357

    Acute respiratory distress syndrome (ARDS) is a clinically defined syndrome of hypoxia and bilateral pulmonary infiltrates due to inflammatory pathways triggered by pulmonary and nonpulmonary insults, and ARDS is pathologically correlated with diffuse alveolar damage. Estimates of ARDS's impact in the developed world vary widely, with some of the discrepancies attributed to marked differences in the availability of intensive care beds and mechanical ventilation. Almost nothing is known about the epidemiology of ARDS in the developing world, in part due to a clinical definition requiring positive pressure ventilation, arterial blood gases, and chest radiography. Current frameworks for comparing the epidemiology of death and disability across the world including the GBD (Global Burden of Disease Study) 2010 are ill-suited to quantifying critical illness syndromes including ARDS. Modifications to the definition of ARDS to allow a provision for environments without the capacity for positive pressure ventilation, and to allow for alternate diagnostic techniques including pulse oximetry and ultrasound, may make it possible to quantify and describe the impact of ARDS in the global context.

The patient's medical history contained no evidence of previous pulmonary pathology, preoperative chest X-ray study revealed neither focal nor infiltrative changes in the lungs. On day 5 after extensive surgical intervention with the use of a parenteral beta-lactam antibiotic, the patient developed acute respiratory distress the symptoms of which increased wavelike during the next 4.5 weeks in association with subfebrility, leukocytosis, enhanced ESR and large shaded areas in the lungs. These conditions were regarded as signs of pneumonia that required the application of increasingly more powerful beta-lactam antibiotics. All these symptoms became less apparent and completely disappeared within 2 days and 1 week respectively after withdrawal of the antibiotics and prescription of parenteral prednisolone. It confirmed the iatrogenic origin of lung lesions regarded by the authors as recurring acute respiratory distress syndrome caused by beta-lactam antibiotics.

    Background Spouses of cancer survivors experience both positive and negative effects from caregiving. However, it is less clear what role spousal well-being may have on cancer survivors. This study aimed to determine the impact of spousal psychosocial factors on survivor depressed mood and whether this association differed by gender. Methods We examined longitudinal data on cancer survivors and their spouses (n=910 dyads) from the 2004-2012 Medical Expenditures Panel Survey and a matched sample of cancer-free dyads. Subjects reported depressed mood, psychological distress, and mental and physical health-related quality of life (HRQoL) at two time points (T1/T2). Dyadic multilevel models evaluated the impact of psychosocial factors at T1 on depressed mood at T2, controlling for sociodemographics, cancer type, survivor treatment status, and depressed mood at T1. Results Cancer survivors whose spouses reported depressed mood at T1 were 4.27 times more likely to report depressed mood at T2 (95% CI=2.01-9.07); this was stronger for female survivors (OR=9.49; 95% CI=2.42-37.20). Better spousal mental and physical HRQoL at T1 were associated with a 30% decrease in survivor depressed mood risk at T2. Most spillover effects were not observed in comparison dyads. Conclusion Depressed mood and poor HRQoL in spouses may increase the risk of depressed mood in cancer survivors. The risk may be especially strong for female survivors. Impact Identifying and improving spousal mental health and HRQoL problems may reduce the risk of depressed mood in cancer survivors.

    Acute Respiratory Distress Syndrome (ARDS) is due to many causes. The absence of a universal definition up until now has led to a series of practical problems for a definitive diagnosis. The incidences of ARDS and Acute Lung Injury (ALI) vary widely in the current literature. The American-European Consensus Conference definition has been applied since its publication in 1994 and has helped to improve knowledge about ARDS. However, 18 years later, in 2011, the European Intensive Medicine Society, requested a team of international experts to meet in Berlin to review the ARDS definition. The purpose of the Berlin definition is not to use it as a prognostic tool, but to improve coherence between research and clinical practice.

    Acute respiratory distress syndrome (ARDS) is common in critically ill patients admitted to intensive care units (ICU). ARDS results in increased use of critical care resources and healthcare costs, yet the overall mortality associated with these conditions remains high. Research focusing on preventing ARDS and identifying patients at risk of developing ARDS is necessary to develop strategies to alter the clinical course and progression of the disease. To date, few strategies have shown clear benefits. One of the most important obstacles to preventive interventions is the difficulty of identifying patients likely to develop ARDS. Identifying patients at risk and implementing prevention strategies in this group are key factors in preventing ARDS. This review will discuss early identification of at-risk patients and the current prevention strategies. PMID:23617961

    In a crossover trial left ventricular output (LVO), cerebral blood flow velocity (CBFV), and resistance index (RI) of the anterior cerebral artery were compared using Doppler ultrasonography, in eight preterm infants with respiratory distress syndrome (RDS) during conventional mechanical ventilation and high frequency oscillation. LVO was 14% to 18% lower with high frequency oscillation. There were no significant changes in CBFV. On the first day of life there was a trend towards lower RI on high frequency oscillation; the fall in LVO on high frequency oscillation was not related to lung hyperinflation. Changes in ventilation type (from conventional mechanical ventilation to high frequency oscillation, or vice versa) can induce significant LVO changes in preterm infants with RDS. PMID:8777679

    1979-03-01

    Tracheal or pharyngeal aspirates were collected in 50 newborn infants with and without respiratory distress syndrome (RDS). After lipid extraction the phospholipids were analyzed with 2-dimensional thin layer chromatography. Surface-active are lecithin (PC), phosphatidylglycerol (PG), and phosphatidylinositol (PI). Newborn infants with RDS always have a complete lack of PG, which makes up to 11% of phospholipid-phosphors in mature newborns. In all infants with and without RDS, a sharp increase of PC occurs in the lung effluent after birth. The recovery from RDS is characterized by marked changes of PI: this phospholipid rises up to twice its initial value if the infants survive. The PI-increase parallels the clinical improvement and reaches its maximum usually on the 5th day of life. At the time of the PI-peak, the infants' surfactant function is sufficient to maintain alveolar stability with spontaneous breathing. In infants dying from RDS the PI-increase was not observed.

    No major trial evaluating prone positioning for acute respiratory distress syndrome (ARDS) has incorporated a high-positive end-expiratory pressure (high-PEEP) strategy despite complementary physiological rationales. We evaluated generalizability of three recent proning trials to patients receiving a high-PEEP strategy. All trials employed a relatively low-PEEP strategy. After protocol ventilator settings were initiated and the patient was positioned per treatment assignment, post-intervention PEEP was not more than 5 cm H2O in 16.7 % and not more than 10 cm H2O in 66.0 % of patients. Post-intervention PEEP would have been nearly twice the set PEEP had a high-PEEP strategy been employed. Use of either proning or high-PEEP likely improves survival in moderate-severe ARDS; the role for both concomitantly remains unknown.

    Respiratory distress syndrome (RDS) among preterm infants is typically due to a quantitative deficiency of pulmonary surfactant. Aside from the degree of prematurity, diverse environmental and genetic factors can affect the development of RDS. The variance of the risk of RDS in various races/ethnicities or monozygotic/dizygotic twins has suggested genetic influences on this disorder. So far, several specific mutations in genes encoding surfactant-associated molecules have confirmed this. Specific genetic variants contributing to the regulation of pulmonary development, its structure and function, or the inflammatory response could be candidate risk factors for the development of RDS. This review summarizes the background that suggests the genetic predisposition of RDS, the identified mutations, and candidate genetic polymorphisms of pulmonary surfactant proteins associated with RDS.

    Enhanced intrapulmonary fibrin deposition as a result of abnormal broncho-alveolar fibrin turnover is a hallmark of acute respiratory distress syndrome (ARDS), pneumonia and ventilator-induced lung injury (VILI), and is important to the pathogenesis of these conditions. The mechanisms that contribute to alveolar coagulopathy are localized tissue factor-mediated thrombin generation, impaired activity of natural coagulation inhibitors and depression of bronchoalveolar urokinase plasminogen activator-mediated fibrinolysis, caused by the increase of plasminogen activator inhibitors. There is an intense and bidirectional interaction between coagulation and inflammatory pathways in the bronchoalveolar compartment. Systemic or local administration of anticoagulant agents (including activated protein C, antithrombin and heparin) and profibrinolytic agents (such as plasminogen activators) attenuate pulmonary coagulopathy. Several preclinical studies show additional anti-inflammatory effects of these therapies in ARDS and pneumonia. PMID:23114008

    Objective Patients diagnosed with lung cancer report high levels of stigma and psychological distress. This study examined posttraumatic growth among lung cancer survivors as a potential buffer against this relationship between stigma and psychological distress and examined how these relationships differed by the timing of quitting smoking (pre versus post-diagnosis). Methods Stages IA and IB non-small-cell lung cancer survivors (N= 141) who were former smokers, 1–6 years post-treatment, and had no evidence of disease completed standardized questionnaires assessing stigma, posttraumatic growth, timing of quitting smoking history, and psychological distress. Results Hierarchical linear regression and simple slope analyses indicated that among those who quit smoking prior to diagnosis (pre-diagnosis quitters), stigma had a positive association with psychological distress at high levels of posttraumatic growth (p = 0.003) and had a positive (but non-significant) association with psychological distress among those with low levels of posttraumatic growth (p = 0.167). Among those who quit smoking after diagnosis (post-diagnosis quitters), stigma had a positive association with psychological distress among those with low levels of posttraumatic growth (p = 0.004) but had no relationship among those with high levels of posttraumatic growth (p = 0.880). Conclusions Findings indicate that posttraumatic growth buffers against the negative effects of stigma on psychological distress but only among post-diagnosis quitters. Future interventions could focus on fostering posttraumatic growth as a way to decrease the negative effects of stigma. PMID:25345591

    The present study evaluated whether differences in the type of radiotherapy, disease stage, and self-esteem influence psychological distress and quality of life (QOL) among cervical cancer survivors. Sixty survivors, after radiotherapy, chemoradiotherapy, or postoperative radiotherapy for cervical cancer, participated in the study. The participants were asked to complete questionnaires during follow-up visits. The questionnaires included the Japanese version of the Hospital Anxiety and Depression Scale, the Functional Assessment of Cancer Therapy-General, and the Rosenberg Self-esteem Scale. The results indicated that psychological distress and QOL in cervical cancer survivors were not significantly different among treatment modalities and disease stage. Psychological distress and QOL differed significantly in accordance with the survivor's self-esteem. Survivors in the high self-esteem group had lower levels of anxiety and depression and higher QOL scores (emotional and social/family aspects of QOL and total QOL) than those in the low self-esteem group. Psychosocial support with consideration of a patient's self-esteem is necessary throughout and beyond radiotherapy for cervical cancer.

    The field of "Public Health in Disasters and Complex Emergencies" is replete with either epidemiological studies or studies in the area of hospital preparedness and emergency care. The field is dominated by hospital-based or emergency phase-related literature, with very little attention on long-term health and mental health consequences. The social science, or the public mental health perspective, too, is largely missing. It is in this context that the case report of the November 26, 2008 Mumbai terror attack survivors is presented to bring forth the multi-dimensional and dynamic long-term impacts, and their consequences for psychological well-being, two years after the incident. Based on literature, the report formulates a theoretical framework through which the lived experiences of the survivors is analyzed and understood from a social science perspective. This report is an outcome of the ongoing work with the survivors over a period of two years. A mixed methodology was used. It quantitatively captures the experience of 231 families following the attack, and also uses a self-reporting questionnaire (SRQ), SRQ20, to understand the psychological distress. In-depth qualitative case studies constructed from the process records and in-depth interviews focus on lived experiences of the survivors and explain the patterns emerging from the quantitative analysis. This report outlines the basic profile of the survivors, the immediate consequences of the attack, the support received, psychological consequences, and the key factors contributing to psychological distress. Through analysis of the key factors and the processes emerging from the lived experiences that explain the progression of vulnerability to psychological distress, this report puts forth a psychosocial framework for understanding psychological distress among survivors of the November 26, 2008 Mumbai terror attack.

    Associations between pet loss and posthurricane perceived social support and psychological distress were explored. Participants (N = 365) were primarily low-income African American single mothers who were initially part of an educational intervention study. All participants were exposed to Hurricane Katrina, and 47% experienced Hurricane Rita. Three waves of survey data, two from before the hurricanes, were included. Sixty-three participants (17.3%) reported losing a pet due to the hurricanes and their aftermath. Pet loss significantly predicted postdisaster distress, above and beyond demographic variables, pre- and postdisaster perceived social support, predisaster distress, hurricane-related stressors, and human bereavement, an association that was stronger for younger participants. Pet loss was not a significant predictor of postdisaster perceived social support, but the impact of pet loss on perceived social support was significantly greater for participants with low levels of predisaster support.

    Acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) are characterized by rapid-onset respiratory failure following a variety of direct and indirect insults to the parenchyma or vasculature of the lungs. Mortality from ALI/ARDS is substantial, and current therapy primarily emphasizes mechanical ventilation and judicial fluid management plus standard treatment of the initiating insult and any known underlying disease. Current pharmacotherapy for ALI/ARDS is not optimal, and there is a significant need for more effective medicinal chemical agents for use in these severe and lethal lung injury syndromes. To facilitate future chemical-based drug discovery research on new agent development, this paper reviews present pharmacotherapy for ALI/ARDS in the context of biological and biochemical drug activities. The complex lung injury pathophysiology of ALI/ARDS offers an array of possible targets for drug therapy, including inflammation, cell and tissue injury, vascular dysfunction, surfactant dysfunction, and oxidant injury. Added targets for pharmacotherapy outside the lungs may also be present, since multiorgan or systemic pathology is common in ALI/ARDS. The biological and physiological complexity of ALI/ARDS requires the consideration of combined-agent treatments in addition to single-agent therapies. A number of pharmacologic agents have been studied individually in ALI/ARDS, with limited or minimal success in improving survival. However, many of these agents have complementary biological/biochemical activities with the potential for synergy or additivity in combination therapy as discussed in this article. PMID:18691048

    Tumor lysis syndrome is a serious and dangerous complication usually associated with antiblastic treatment in some malignancies characterized by high cell turn-over. Mild or severe electrolyte abnormalities including high serum levels of uric acid, potassium, phosphorus, creatinine, bun and reduction of calcium can be responsible for multi-organ failure, involving mostly kidneys, heart and central nervous system. Renal damage can be followed by acute renal failure, weight gain, progressive liver impairment, overproduction of cytokines, and subsequent maintenance of multi-organ damage. Life-threatening acute respiratory failure associated with tumor lysis syndrome is rare. We describe a child with T-cell acute lymphoblastic leukemia, who developed an unusually dramatic tumor lysis syndrome, after administration of the first low doses of steroid, that was rapidly associated with severe acute respiratory distress syndrome. Subsequent clinical course and treatment modalities that resulted in the gradual and full recovery of the child are also described. PMID:25918625

[Subjects and Methods] The clinical data of 58 patients with ARDS that required mechanical ventilation in two intensive care units (ICU) was reviewed. [Results] Endotracheal intubation was performed in 55.17% of the total patients and in 39.53% of the patients who received NIV treatment. The APACHE II score for patients who only received IV was significantly higher than those who only underwent NIV (25.67 ± 5.30 vs. 18.12 ± 7.20). However, there were no significant differences in 28-day/90-day survival rates, duration of mechanical ventilation, and length of ICU stay between these two groups. For patients from a NIV-to-IV group, the APACHE II scores before endotracheal intubation were higher than the scores from IV patients (26.12 ± 4.08 vs. 21.94 ± 6.10). The 90-day survival rate in the NIV-to-IV group was significantly lower than that of the IV-only group (23.5% vs. 73.3%), although there was no difference in the 28-day survival rate between the two groups. [Conclusion] The application of NIV reduces the percentage of patients requiring endotracheal intubation.

    The administration of an appropriate volume of intravenous fluids, while avoiding fluid overload, is a major challenge in the pediatric intensive care unit. Despite our efforts, fluid overload is a very common clinical observation in critically ill children, in particular in those with pediatric acute respiratory distress syndrome (PARDS). Patients with ARDS have widespread damage of the alveolar–capillary barrier, potentially making them vulnerable to fluid overload with the development of pulmonary edema leading to prolonged course of disease. Indeed, studies in adults with ARDS have shown that an increased cumulative fluid balance is associated with adverse outcome. However, age-related differences in the development and consequences of fluid overload in ARDS may exist due to disparities in immunologic response and body water distribution. This systematic review summarizes the current literature on fluid imbalance and management in PARDS, with special emphasis on potential differences with adult patients. It discusses the adverse effects associated with fluid overload and the corresponding possible pathophysiological mechanisms of its development. Our intent is to provide an incentive to develop age-specific fluid management protocols to improve PARDS outcomes. PMID:27047904

    2015-01-01

    Abstract Severe adenovirus infection in children can manifest with acute respiratory distress syndrome (ARDS) and respiratory failure, leading to the need for prolonged mechanical support in the form of either mechanical ventilation or extracorporeal life support. Early extracorporeal membrane oxygenation (ECMO) intervention for children with ARDS should be considered if selection criteria fulfill. We report on a 9-month-old boy who had adenovirus pneumonia with rapid progression to ARDS. Real-time polymerase chain reaction tests of sputum and pleural effusion samples confirmed adenovirus serotype 7. Chest x-rays showed progressively increasing infiltrations and pleural effusions in both lung fields within 11 days. Because conventional ARDS therapies failed, we initiated ECMO with high-frequency oscillatory ventilation (HFOV) for 9 days. Chest x-rays showed gradual improvements in lung expansion. This patient was subsequently discharged after a hospital stay of 38 days. Post-ECMO and adenovirus sequelae were followed in our outpatient department. Adenovirus pneumonia in children can manifest with severe pulmonary morbidity and respiratory failure. The unique lung recruitment by HFOV can be a useful therapeutic option for severe ARDS patients when combined with sufficient lung rest provided by ECMO. PMID:25997046

    There is no well-stated practical guideline for mechanically ventilated patients with or without acute respiratory distress syndrome (ARDS). We generate strong (1) and weak (2) grade of recommendations based on high (A), moderate (B) and low (C) grade in the quality of evidence. In patients with ARDS, we recommend low tidal volume ventilation (1A) and prone position if it is not contraindicated (1B) to reduce their mortality. However, we did not support high-frequency oscillatory ventilation (1B) and inhaled nitric oxide (1A) as a standard treatment. We also suggest high positive end-expiratory pressure (2B), extracorporeal membrane oxygenation as a rescue therapy (2C), and neuromuscular blockage for 48 hours after starting mechanical ventilation (2B). The application of recruitment maneuver may reduce mortality (2B), however, the use of systemic steroids cannot reduce mortality (2B). In mechanically ventilated patients, we recommend light sedation (1B) and low tidal volume even without ARDS (1B) and suggest lung protective ventilation strategy during the operation to lower the incidence of lung complications including ARDS (2B). Early tracheostomy in mechanically ventilated patients can be performed only in limited patients (2A). In conclusion, of 12 recommendations, nine were in the management of ARDS, and three for mechanically ventilated patients. PMID:27790273

    Acute respiratory distress syndrome (ARDS) is one of the major causes of ICU deaths. Extracorporeal lung assist (ECLA) has been used as a rescue therapy for most severe form of ARDS. However, its survival benefit had not been shown until CESAR trial in 2009. This has been because the concept of lung protective ventilation strategy had not yet known. Since CESAR trial, the clinical application of ECLA for ARDS as a method to achieve lung rest has wide spread. The effectiveness is further appreciated during the 2009 H1N1 influenza pandemic. The succeeded countries achieved building the transportation systems to collect ECLA patients. With the accumulating evidences of survival benefit, the long-term outcome such as pulmonary function and quality of life are in concern. PumplessECLA which is a newly developed form of ECLA is also reviewed. In this essay we will firstly review the basics of ARDS and ECLA. Then the historical development of ECLA evidences for ARDS are reviewed. PMID:25567336

    Antisynthetase syndrome has been recognized as an important cause of autoimmune inflammatory myopathy in a subset of patients with polymyositis and dermatomyositis. It is associated with serum antibody to aminoacyl-transfer RNA synthetases and is characterized by a constellation of manifestations, including fever, myositis, interstitial lung disease, mechanic's hand-like cutaneous involvement, Raynaud phenomenon, and polyarthritis. Lung disease is the presenting feature in 50% of the cases. We report a case of a 60-year-old female with acute respiratory distress syndrome (ARDS), which later proved to be an unexpected and initial manifestation of anti-Jo-1 antibody-positive antisynthetase syndrome. The present case showed resolution of ARDS after treatment with high-dose corticosteroids. Given that steroids are not greatly beneficial in the treatment of ARDS, it is likely that the improvement of the respiratory symptoms in this patient also resulted from the prompt suppression of the inflammatory systemic response by corticosteroids.

    Background: Catastrophic antiphospholipid syndrome (APS) is defined as life threatening multiple organ thromboses developing simultaneously or over a short period. The survival rate of catastrophic APS is about 50%, but the long term outcome of patients who survive is unknown. Objective: To determine the long term outcome of patients with catastrophic APS and provide further information on patients who survived. Patients and methods: The clinical characteristics and outcomes of 130 patients with catastrophic APS have been reported previously. Six new cases were recently added to this series. Based on these publications, the authors who reported patients who had survived were contacted. Each author was asked (a) what treatment they gave their patients after the catastrophic APS; (b) if their patients had any further thrombosis. Results: 63/136 (46%) patients died at the initial event. Of the remaining 73 patients, information was available for 58 (79%). Thirty eight (66%) patients did not develop further APS related events during an average follow up of 67.2 months. Eleven (19%) patients developed further APS related events but were still alive. No patients developed further catastrophic APS. Nine (16%) patients died: due to multiple organ failure (three patients); myelofibrosis (one); pneumonia (one); and APS related events (four). Conclusion: Sixty six per cent of patients who survive an initial catastrophic APS event remained symptom free with anticoagulation during an average follow up of 67.2 months. Twenty six per cent of the survivors developed further APS related events and the mortality rate of these patients was about 25%. PMID:12759289

Data were collected in the year prior to the hurricane as well as approximately 1 and 3 years thereafter. Using Latent Class Growth Analysis (LCGA), we detected 6 distinct trajectory groups. Over half of the participants fit into a trajectory consistent with resilience; that is, they maintained low levels of psychological distress over the course of the study, but experienced an elevation in symptoms at the first predisaster time point followed by a return to predisaster levels. The other trajectories reflected a range of psychological responses to disasters and indicated that predisaster functioning had a major influence on postdisaster psychological outcomes. Degree of exposure to hurricane-related stressors, experiences of human and pet bereavement, perceived social support, and socioeconomic status were significant predictors of trajectory group membership. Implications for research and policy are discussed. PMID:23889030

    Many breast cancer survivors report a loss of sexual desire and arousability, consonant with the new DSM-V category of female sexual interest/arousal disorder. The cause of decreased sexual desire and pleasure after treatment for cancer is unknown. One possibility is that cancer, or treatment for cancer, damages brain circuits that are involved in reward-seeking. To test the hypothesis that brain reward systems are involved in decreased sexual desire in breast cancer survivors, we used functional magnetic resonance imaging (fMRI) to compare brain responses to erotica and other emotional stimuli in two groups of women previously treated for breast cancer with chemotherapy: those who were distressed about a perceived loss of sexual desire and those who may have had low desire, but were not distressed about it. Women distressed about their desire had reduced brain responses to erotica in the anterior cingulate and dorsolateral prefrontal cortex, which are part of the brain reward system. This study is the first to demonstrate, in cancer survivors, that problems with sexual desire/arousability are associated with blunted brain responses to erotica in reward systems. Future research is necessary to determine whether brain responses differ as a result of chemotherapy, hormone therapy, and menopausal status. This may contribute to the development of new, evidence-based interventions for one of the most prevalent and enduring side effects of cancer treatment. PMID:23955492

    Acute respiratory distress syndrome (ARDS) is a life threatening respiratory failure due to lung injury from a variety of precipitants. Pathologically ARDS is characterised by diffuse alveolar damage, alveolar capillary leakage, and protein rich pulmonary oedema leading to the clinical manifestation of poor lung compliance, severe hypoxaemia, and bilateral infiltrates on chest radiograph. Several aetiological factors associated with the development of ARDS are identified with sepsis, pneumonia, and trauma with multiple transfusions accounting for most cases. Despite the absence of a robust diagnostic definition, extensive epidemiological investigations suggest ARDS remains a significant health burden with substantial morbidity and mortality. Improvements in outcome following ARDS over the past decade are in part due to improved strategies of mechanical ventilation and advanced support of other failing organs. Optimal treatment involves judicious fluid management, protective lung ventilation with low tidal volumes and moderate positive end expiratory pressure, multi-organ support, and treatment where possible of the underlying cause. Moreover, advances in general supportive measures such as appropriate antimicrobial therapy, early enteral nutrition, prophylaxis against venous thromboembolism and gastrointestinal ulceration are likely contributory reasons for the improved outcomes. Although therapies such as corticosteroids, nitric oxide, prostacyclins, exogenous surfactants, ketoconazole and antioxidants have shown promising clinical effects in animal models, these have failed to translate positively in human studies. Most recently, clinical trials with β2 agonists aiding alveolar fluid clearance and immunonutrition with omega-3 fatty acids have also provided disappointing results. Despite these negative studies, mortality seems to be in decline due to advances in overall patient care. Future directions of research are likely to concentrate on identifying potential

    2015-01-01

    Acute Respiratory Distress Syndrome (ARDS) is a severe lung inflammatory disorder with a 30–50% mortality. Sepsis and pneumonia are the leading causes of ARDS. On the cellular level there is pulmonary capillary endothelial cell permeability and fluid leakage into the pulmonary parenchyma, followed by neutrophils, cytokines and an acute inflammatory response. When fluid increases in the interstitium then the outward movement continues and protein rich fluid floods the alveolar spaces through the tight junctions of the epithelial cells. Neutrophils play an important role in the development of pulmonary edema associated with acute lung injury or ARDS. Animal studies have shown that endothelial injury appears within minutes to hours after Acute Lung Injury (ALI) initiation with resulting intercellular gaps of the endothelial cells. The Endothelial Cell (EC) gaps allow for permeability of fluid, neutrophils and cytokines into the pulmonary parenchymal space. The neutrophils that infiltrate the lungs and migrate into the airways express pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and contribute to both the endothelial and epithelial integrity disruption of the barriers. Pharmacological treatments have been ineffective. The ARDS Network trial identified low tidal volume mechanical ventilation, positive end expiratory pressure and fluid management guidelines that have improved outcomes for patients with ARDS. Extracorporeal membrane oxygenation is used in specialized centers for severe cases. Prone positioning has recently proven to have significantly decreased ventilator days and days in the intensive care unit. Current investigation includes administration of mesenchymal stem cell therapy, partial fluid ventilation, TIP peptide nebulized administration and the continued examination of pharmacologic drugs.

  1. Nutrition: A Primary Therapy in Pediatric Acute Respiratory Distress Syndrome

    Appropriate nutrition is an essential component of intensive care management of children with acute respiratory distress syndrome (ARDS) and is linked to patient outcomes. One out of every two children in the pediatric intensive care unit (PICU) will develop malnutrition or have worsening of baseline malnutrition and present with specific micronutrient deficiencies. Early and adequate enteral nutrition (EN) is associated with improved 60-day survival after pediatric critical illness, and, yet, despite early EN guidelines, critically ill children receive on average only 55% of goal calories by PICU day 10. Inadequate delivery of EN is due to perceived feeding intolerance, reluctance to enterally feed children with hemodynamic instability, and fluid restriction. Underlying each of these factors is large practice variation between providers and across institutions for initiation, advancement, and maintenance of EN. Strategies to improve early initiation and advancement and to maintain delivery of EN are needed to improve morbidity and mortality from pediatric ARDS. Both, over and underfeeding, prolong duration of mechanical ventilation in children and worsen other organ function such that precise calorie goals are needed. The gut is thought to act as a “motor” of organ dysfunction, and emerging data regarding the role of intestinal barrier functions and the intestinal microbiome on organ dysfunction and outcomes of critical illness present exciting opportunities to improve patient outcomes. Nutrition should be considered a primary rather than supportive therapy for pediatric ARDS. Precise nutritional therapies, which are titrated and targeted to preservation of intestinal barrier function, prevention of intestinal dysbiosis, preservation of lean body mass, and blunting of the systemic inflammatory response, offer great potential for improving outcomes of pediatric ARDS. In this review, we examine the current evidence regarding dose, route, and timing of nutrition

    Mechanisms underlying pediatric acute respiratory distress syndrome (PARDS) are poorly understood. The recent implication of circulating nucleosomes as pathogenic in sepsis and trauma-associated ARDS in adults led us to investigate the significance of nucleosomes in PARDS. We conducted a prospective, observational study on children with PARDS at the Children's Hospital of Philadelphia between July 2014 and September 2015. Plasma was collected within 48 h of PARDS onset and nucleosomes quantified by enzyme-linked immunosorbent assay. Samples from 76 children with PARDS (11 deaths, 14%) were collected early [median 15 (IQR 7, 21) h] after PARDS onset. Nucleosome levels were higher in nonsurvivors [0.59 AU (IQR 0.46, 0.84)] relative to survivors [0.21 AU (IQR 0.08, 0.33), rank sum P < 0.001]. Nucleosome levels were not associated with either Berlin (P = 0.845) or PALICC (P = 0.886) oxygenation categories, nor with etiology of PARDS (P = 0.527). Nucleosomes were correlated with increasing numbers of nonpulmonary organ failures (P = 0.009 for trend), and were higher in patients whose PaO2 /FiO2 worsened (P = 0.012) over the first 72 h of PARDS. In regression analysis, nucleosome levels were independently associated with mortality after adjusting for either age, severity of illness score, number of nonpulmonary organ failures, vasopressor score, or PaO2 /FiO2 (all P < 0.05). In conclusion, plasma nucleosome levels in early PARDS were associated with increased mortality, correlated with number of nonpulmonary organ failures, and preceded worsening oxygenation. The potential utility of this biomarker for prognostication, risk stratification, and mechanistic insight should be investigated further. PMID:27130528

    Abstract Most epidemiological studies of acute respiratory distress syndrome (ARDS) have been conducted in western countries, and studies in Asia are limited. The aim of our study was to evaluate the incidence, in-hospital mortality, and 1-year mortality of ARDS in Taiwan. We conducted a nationwide inpatient cohort study based on the Taiwan National Health Insurance Research Database between 1997 and 2011. A total of 40,876 ARDS patients (68% male; mean age 66 years) were identified by International Classification of Diseases, 9th edition coding and further analyzed for clinical characteristics, medical costs, and mortality. The overall crude incidence of ARDS was 15.74 per 100,000 person-years, and increased from 2.53 to 19.26 per 100,000 person-years during the study period. The age-adjusted incidence of ARDS was 15.19 per 100,000 person-years. The overall in-hospital mortality was 57.8%. In-hospital mortality decreased from 59.7% in 1997 to 47.5% in 2011 (P < 0.001). The in-hospital mortality rate was lowest (33.5%) in the youngest patients (age 18–29 years) and highest (68.2%) in the oldest patients (>80 years, P < 0.001). The overall 1-year mortality rate was 72.1%, and decreased from 75.8% to 54.7% during the study period. Patients who died during hospitalization were older (69 ± 17 versus 62 ± 19, P < 0.001) and predominantly male (69.8% versus 65.3%, P < 0.001). In addition, patients who died during hospitalization had significantly higher medical costs (6421 versus 5825 US Dollars, P < 0.001) and shorter lengths of stay (13 versus 19 days, P < 0.001) than patients who survived. We provide the first large-scale epidemiological analysis of ARDS incidence and outcomes in Asia. Although the overall incidence was lower than has been reported in a prospective US study, this may reflect underdiagnosis by International Classification of Diseases, 9th edition code and identification of only patients with more severe ARDS in this

    A 9-year-old girl with nephrotic syndrome visited a local hospital after developing fever, chills, and edematous changes and multiple hemorrhagic bullae on both legs over 2 days. Cultures of blood and an aspirate from the bullae yielded Vibrio vulnificus. The patient was transferred to our hospital because of persistent fever, generalized edema, acute renal failure, and disseminated intravascular coagulopathy. We treated this patient as a V. vulnificus infection complicated with necrotizing fasciitis. With minocycline and ceftazidime combination therapy was instituted. Emergency fasciotomy and continuous peritoneal dialysis were performed. The patient developed acute respiratory distress syndrome (ARDS) during the hospitalization, requiring intubation and mechanical ventilation. She eventually died. The histopathological findings showed diffuse alveolar damage with lobular pneumonitis. Hyaline membranes, composed of proteinaceous exudate and cellular debris, covered the alveolar surfaces. Microscopic examinations of lung could not distinguish the effects of cytolysin from other insults to lungs that occur in ARDS. This report highlights the postmortem pathological findings in V. vulnificus infection in a child with nephrotic syndrome complicated by ARDS.

    Background The acute respiratory distress syndrome (ARDS) is a non‐cardiogenic form of pulmonary oedema characterised by severe hypoxaemia refractory to oxygen therapy, with diffuse pulmonary infiltrates on chest radiographs. It can be precipitated by various serious medical and surgical conditions, including systemic autoimmune diseases. The “catastrophic” variant of the antiphospholipid syndrome (APS) is an accelerated form of this systemic autoimmune condition which results in multiorgan failure because of multiple small vessel occlusions. Objective To analyse the clinical and laboratory characteristics of patients with catastrophic APS who develop ARDS. Methods Cases with ARDS were selected from the web site based international registry of patients with catastrophic APS (CAPS registry) (http://www.med.ub.es/MIMMUN/FORUM/CAPS.HTM) and their characteristics examined. Results Pulmonary involvement was reported in 150 of 220 patients with catastrophic APS (68%) and 47 patients (21%) were diagnosed as having ARDS. Nineteen (40%) of these patients died. Pathological studies were undertaken in 10 patients and thrombotic microangiopathy was present in seven. There were no differences in age, sex, precipitating factors, clinical manifestations, or mortality between catastrophic APS patients with and without ARDS. Conclusions ARDS is the dominant pulmonary manifestation of catastrophic APS. Thus the existence of ARDS in the context of an APS makes it necessary to rule out the presence of the catastrophic variant of this syndrome. PMID:15919677

    Several authors have speculated that the lack of consistency regarding the relationship between symptoms of posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) is caused by third variables. Recalled peritraumatic distress (PD) may operate as a third variable because previous research suggests that both PTSD and PTG correlate with recalled PD. Therefore, the present study explored how recalled PD impacts the relationship between PTSD and PTG. An Internet questionnaire on PTSD symptom severity, recalled PD, and PTG was administered to 678 survivors of violent crime. The results suggested that recalled PD suppresses the association between PTSD symptom severity and PTG. In addition, a significant association between the interaction term of PTSD symptom severity and recalled PD and PTG was observed. Simple slopes tests indicated that self-reported PTSD symptoms were negatively associated with PTG but only among survivors with high levels of PD.

    Patients with acute respiratory distress syndrome may require high positive end-expiratory pressure (PEEP) levels, though the optimum level remains to be established. Several clinical trials have compared high PEEP levels versus conventional PEEP. Overall, although high PEEP levels improve oxygenation and are safe, they do not result in a significant reduction of the mortality rates. Nevertheless, some metaanalyses have revealed 2 situations in which high PEEP may decrease mortality: When used in severe distress and when PEEP is set following the characteristics of lung mechanics. Five studies have explored this latter scenario. Unfortunately, all of them have small sample sizes and have used different means to determine optimum PEEP. It is therefore necessary to conduct studies of sufficient sample size to compare the treatment of patients with severe acute respiratory distress syndrome, using a protective ventilation strategy with high PEEP guided by the characteristics of lung mechanics and ventilation with the protocol proposed by the ARDS Network.

    After successful rescue from drowning there may develop a situation which is called secondary drowning, resulting in acute respiratory distress characterized by interstitial pulmonary oedema, hypoxaemia, hypercapnia and acidosis during drowning, direct alteration of the alveolar membrane by aspirated water and particulate matters and a volume overloading by adsorption and--not seldom--inept therapy. This situation requires mechanical ventilation and forced diuresis, combined with high doses of steroids, antibiotics and digitalis. We present the case of an eleven year old patient whose clinical course demonstrate the necessity of exact clinical observation after rescue from drowning. After development of acute respiratory distress only the immediate utilization of the therapeutic modalities of an intensive care may result in a satisfactory outcome. Four months later our patient had normal pulmonary function except for a moderate reduction of compliance.

    Objective Soluble ST2 (sST2) is a biomarker of myocardial strain and inflammation. The characteristics of acute respiratory distress syndrome (ARDS) include inflammation and cardiovascular dysfunction. We sought to determine whether plasma sST2 concentration is associated with outcome and response to conservative fluid management, and whether sST2 concentration discriminates ARDS from decompensated heart failure (HF). Design, Setting, and Patients We assayed plasma sST2 concentrations in 826 patients in the Fluid and Catheter Treatment Trial (FACTT), a multi-center randomized controlled trial of conservative fluid management in ARDS, as well as a cohort of patients with decompensated HF. We tested whether sST2 was associated with outcome, response to therapy, and diagnostic utility for ARDS vs. HF. Measurements and Main Results Non-survivors had higher day 0 (P<.0001) and day 3 (P<.0001) sST2 concentrations. After adjustment for severity of illness, higher sST2 concentration was associated with mortality, with odds ratio (ORadj) 1.47 (95% confidence interval [CI] 0.99 – 2.20, P=.06) at day 0, 2.94 (95% CI 2.00 – 4.33, P<.0001) at day 3, and 3.63 (95% CI 2.38 – 5.53, P<.0001) if sST2 increased between days. Cumulative fluid balance was more positive among patients with higher day 0 (median 5212 mL, interquartile range [IQR] 200 – 12284 vs. 2020 mL, −2034 – 7091; P<0.0001), and day 3 sST2 (median 7678 mL, IQR 2217 – 14278 vs. 1492 mL, −2384 – 6239; P<0.0001). sST2 showed excellent discriminative ability between the FACTT and HF populations (Area under ROC curve=0.98, P<0.0001). Conclusions Higher sST2 concentrations are associated with worse outcome in ARDS and may have value for discriminating ARDS from heart failure. PMID:23939353

    Genetic susceptibility may partially explain the clinical variability observed during the course of similar infections. To establish the contribution of genetic host factors in the susceptibility to critical illness, we genotyped 750 subjects (419 at high risk of critical illness) for 14 single nucleotide polymorphisms (SNPs) in the xenobiotics detoxification/oxidative stress and vascular homeostasis metabolic pathways. In the group of nosocomial pneumonia (NP; 268 patients) the risk of acute respiratory distress syndrome (ARDS) is significantly higher for the carriers of CYP1A1 rs2606345 T/T genotypes and AhR rs2066853 G/A-A/A genotypes. AGTR1 rs5186 allele C is more common among NP non-survivors. The duration of stay in intensive care units (ICU) is higher for NP patients with ABCB1 rs1045642-T allele. The cumulative effect of the risk alleles in the genes comprising two sets of genes partners (xenobiotics detoxification: CYP1A1, AhR and RAS family: ACE, AGT, AGTR1) is associated with the development of both NP and ARDS.

    Coping and correlates of psychological distress of Chinese parents of children with Down syndrome were examined and compared to parents of children with language delays or no disabilities. Individual parent scores were used for analyses, with groups and gender of child and parent as independent factors. Down syndrome group parents reported the most frequent use of avoidance coping style, followed by parents of the language delay and no disabilities groups. Compared to parents in the no disabilities group, the other parents reported a higher level of psychological distress, were less optimistic, felt less self-efficacious, and engaged in more frequent use of self-reliance coping style. Main effects for parent gender revealed that mothers engaged in more frequent use of self-reliance, avoidance, and seeking social support coping styles. Mothers also reported a higher level of distress but lower levels of optimism and self-mastery. Intercorrelations among variables showed that avoidance coping style and self-mastery emerged as the two robust correlates of parental distress.

    2013-01-01

    The use of alveolar recruitment manoeuvres for the treatment of acute respiratory distress syndrome is a topic of uncertainty in current critical care practice. Acute respiratory distress syndrome leads to inflammatory atelectasis, which challenges the gas exchange properties of the lung. Recruitment of atelectatic lung tissue requires elevation of transpulmonary pressure. Transpulmonary pressure can be suppressed at a given airway pressure when pleural pressures are elevated. The present review discusses recruitment of lung tissue in detail, highlighting the key research in the field. Differing techniques for recruiting lung tissue, as well as various outcome measures to determine efficacy, are analyzed and critiqued. The commonly used sustained inflation manoeuvre is perhaps regarded as the only strategy to recruit the lung, explaining its prevalence. Staircase recruitment with positive end-expiratory pressure titration is shown to be an equally - if not more - effective therapy that devotes attention to the maintenance of lung recruitment.

    Current treatment of acute respiratory distress syndrome is based on ventilatory support with a lung protective strategy, avoiding the development of iatrogenic injury, including ventilator-induced lung injury. One of the mechanisms underlying such injury is atelectrauma, and positive end-expiratory pressure (PEEP) is advocated in order to avoid it. The indicated PEEP level has not been defined, and in many cases is based on the patient oxygen requirements for maintaining adequate oxygenation. However, this strategy does not consider the mechanics of the respiratory system, which varies in each patient and depends on many factors-including particularly the duration of acute respiratory distress syndrome. A review is therefore made of the different methods for adjusting PEEP, focusing on the benefits of individualized application.

    A 15-year-old patient has been admitted to the intensive care unit for severe respiratory distress syndrome that developed as a result of pneumonia. Interstitial lung edema was confirmed by computer-aided tomography. It was successfully treated by positive pressure ventilation (PPV). Although PEEP did not exceed 7 cm H2O, PPV was complicated by interstitial emphysema, pneumomediastinum, and bilateral pneumothorax as a result of barotrauma. Pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) were monitored. High PCWP values were inconsistent with the diagnosis of acute respiratory distress syndrome. The authors suggest that high PCWP was caused by high intraalveolar pressure, pneumomediastinum, and venule constriction in the hypoxic sites of the lung.

    With a high rate of mortality, acute respiratory distress syndrome (ARDS) has limited treatments options. Immune-enhanced formulas, containing eicosapentaenoic acid, borage oil, and antioxidants, have shown to be beneficial in adults patients with ARDS, decreasing mortality, length of mechanical ventilation, and new organ dysfunction. There is promising research in pediatric patients with improvement in oxygenation status found, but further trials are needed to realize these benefits in pediatric and infant populations.

    Fatal measles is known to occur among immunocompromised adults. We report a rare case of an immunocompetent non-pregnant young lady who suffered from fatal acute respiratory distress syndrome due to measles. Physicians must be vigilant to this deadly presentation of measles even in immunocompetent individuals. We emphasise the inadequacies of vaccination programmes in India reflected not only by the existing high measles-related childhood mortalities, but also an emerging rise in deaths among adults.

    Mechanical ventilation is a fundamental treatment of acute respiratory distress syndrome (ARDS). Despite compliance with the recommendations of protective mechanical ventilation, it can results in serious complications including the pulmonary barotrauma. This is often manifested by a pneumothorax. This observation describes an unusual aspect of barotrauma which is pneumomediastinum. The authors also point out the role of chest imaging in the management of mechanical ventilation during ARDS.

    Background and Aim: Studies on potential biomarkers in experimental models of acute lung injury (ALI) and clinical samples from patients with ALI have provided evidence to the pathophysiology of the mechanisms of lung injury and predictor of clinical outcome. Because of the high mortality and substantial variability in outcomes in patients with acute respiratory distress syndrome (ARDS), identification of biomarkers such as cytokines is important to determine prognosis and guide clinical decision-making. Materials and Methods: In this study, we have included thirty patients admitted to Intensive Care Unit diagnosed with ARDS, and serum samples were collected on day 1 and 7 and were analyzed for serum interleukin-6 (IL-6) and IL-8 by ELISA method, and Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring was done on day 1. Results: The mortality in the patients observed with ARDS was 34%. APACHE II score was significantly higher in nonsurvivors as compared to survivors. There were no significant differences in gender and biochemical and hematological parameters among the survivors and nonsurvivors. Serum IL-6 and IL-8 levels on day 1 were significantly higher in all the ARDS patients as compared to healthy controls and these levels were returned to near-normal basal levels on day 7. The serum IL-6 and IL-8 levels measured on day 7 were of survivors. As compared to survivors, the IL-6 and IL-8 levels were significantly higher in nonsurvivors measured on day 1. Spearman's rank correlation analysis indicated a significant positive correlation of APACHE II with IL-8. By using APACHE II score, IL-6, and IL-8, the receiver operating characteristic curve was plotted and the provided predictable accuracy of mortality (outcome) was 94%. Conclusion: The present study highlighted the importance of measuring the cytokines such as IL-6 and IL-8 in patients with ARDS in predicting the clinical outcome. PMID:27688627

    Acute respiratory distress syndrome (ARDS) remains associated with a poor outcome despite recent major therapeutic advances. Forecasting the outcome of patients suffering from such a syndrome is of a crucial interest and many scores have been proposed, all suffering from limits responsible for important discrepancies. Authors try to elaborate simple, routine and reliable scores but most of them do not consider hemodynamics yet acknowledged as a major determinant of outcome. This article aims at reminding the approach of scoring in ARDS and at deeply describing the most recently published one in order to highlight their main pitfall, which is to forget the hemodynamics.

    A hallmark feature of the Takotsubo syndrome (TTS) is the reversible nature of the observed cardiac dysfunction. This is underlined in diagnostic criteria. However, it would appear this reversibility is a subtle process, and that myocardial catecholamine toxicity can cause lasting permanent abnormalities of myocardial physiology. A growing body of evidence suggests persisting abnormalities may predispose post-TTS patients to cardiac and noncardiac morbidity and mortality. The cardiology community needs to understand more clearly how TTS evolves, how to identify high-risk patients with incomplete resolution, and perform studies to assess which treatment(s) are effective to improve cardiac recovery and clinical outcomes.

    Given the high incidence and mortality of ARDS in critically ill patients, every practitioner needs a bedside approach both for early identification of patients at risk for ARDS and for the appropriate evaluation of patients who meet the diagnostic criteria of ARDS. Recent advances such as the Lung Injury Prediction Score, the Early Acute Lung Injury score, and validation of the SpO2/FiO2 ratio for assessing the degree of hypoxemia are all practical tools to aid the practitioner in caring for patients at risk of ARDS and will likely become more important in the future as more preventative therapies for ARDS are investigated. For patients who meet the diagnostic criteria for ARDS, the practitioner should focus on a thorough search for an underlying cause as well as the concurrent possibility of an underlying disease process that mimics the clinical syndrome of ARDS.

    Positive and negative religious coping strategies and their relation with posttraumatic stress (PTS), psychological distress, and posttraumatic growth (PTG) were examined in the context of Hurricane Katrina. Positive religious coping was hypothesized to be associated with PTG, whereas negative religious coping was hypothesized to be associated with PTS and psychological distress. Low-income mothers (N = 386, mean age = 25.4 years, SD = 4.43) were surveyed before, and 1 and 4 years after the storm. Results from structural regression modeling indicated that negative religious coping was associated with psychological distress, but not PTS. Positive religious coping was associated with PTG. Further analysis indicated significant indirect effects of pre- and postdisaster religiousness on postdisaster PTG through positive religious coping. Findings underscore the positive and negative effect of religious variables in the context of a natural disaster.

    Objective Parents report psychological distress in association with their child's cancer. Reliable tools are needed to screen parental distress over the cancer trajectory. This study aimed to estimate the stability and repeatability of the Distress Thermometer (DT) and the Depression and Anxiety items of the Edmonton Symptom Assessment System-revised (ESAS-r-D; -A) in parents of children diagnosed with cancer. Methods Fifty parents (28 mothers, median age = 44) of clinically stable survivors of childhood solid and brain tumours completed questionnaires about their own distress (DT, ESAS-r-D; -A, Brief Symptom Inventory-18: BSI-18, Patient Health Questionnaire-9: PHQ-9, Generalized Anxiety Disorder-7: GAD-7) and their children’s quality of life (QoL; Peds Quality of Life: PedsQL) twice, with a month interval between the two assessments. At retest, parents also evaluated life events that occurred between the two time points. Hierarchical regressions explored moderators for the temporal stability of test measures. Results Stability estimates were ICC = .78 for the DT, .55 for the ESAS-r-D, and .47 for the ESAS-r-A. Caseness agreement between test and retest was substantial for the DT, fair for the ESAS-r-D, and slight for the ESAS-r-A. Repeatability analyses indicated that the error range for the DT was more than 2 pts below/above actual measurement, whereas it was more than 3 pts for the ESAS-r-A, and 2.5 for the ESAS-r-D. Instability of the DT could be explained by changes in children’s physical QoL, but not by other components of QoL or life events. No moderators of stability could be identified for the ESAS-r items. Conclusions The DT appears to be a fairly stable measure when the respondent's condition is stable yet with a relatively wide error range. Fluctuations in distress-related constructs may affect the temporal stability of the DT. The lower stability of ESAS-r items may result from shorter time-lapse instructions resulting in a greater sensitivity to

    Cryptococcosis is a cosmopolitan but rare opportunistic mycosis which is usually caused by Cryptococcus neoformans. Although the most common and worrisome disease manifestation is meningoencephalitis, pulmonary cryptococcosis has the potential to be lethal. The diagnosis of cryptococcal pneumonia is challenging, given its non-specific clinical and radiographic features. Respiratory failure leading to acute respiratory distress syndrome as a consequence of cryptococcal disease has been infrequently addressed in the literature. We herein present a case of disseminated cryptococcal infection leading to acute respiratory distress syndrome, refractory shock, and multiorgan dysfunction as the initial clinical manifestation in a patient who was newly diagnosed with acquired immunodeficiency syndrome.

    Mitochondrial and microcirculatory distress syndrome (MMDS) can occur during systemic inflammatory response syndrome (SIRS), and is characterized by cytopathic tissue hypoxia uncorrected by oxygen transport optimization, and associated with an acquired defect in the use of oxygen and energy production in mitochondria, leading to multiple organ dysfunction (MOD). We examine the pathogenesis of MMDS, new diagnostic methods, and recent therapeutic approaches adapted to each of the three phases in the evolution of the syndrome. In the initial phase, the aim is prevention and early reversal of mitochondrial dysfunction. Once the latter is established, the aim is to restore flow of the electron chain, mitochondrial respiration, and to avoid cellular energy collapse. Finally, in the third (resolution) stage, treatment should focus on stimulating mitochondrial biogenesis and the repair or replacement of damaged mitochondria.

    Spinal muscular atrophy with respiratory distress syndrome (SMARD1) is a rare cause of early infantile respiratory failure and death. No cases have been currently described from India. Two low-birth-weight infants presented prior to 6 months of age with recurrent apnea and respiratory distress. Both required prolonged ventilation, and had distal arthrogryposis and diaphragmatic eventration. Nerve conduction study revealed motor sensory axonopathy. Genetic testing confirmed mutations in immunoglobulin mu binding protein (IGHMBP2). These two cases establish presence of SMARD1 in our population. Both infants died on discontinuation of ventilation. Antenatal diagnoses done in one pregnancy. Though rare, high index of suspicion is essential in view of poor outcome and aid antenatal counseling.

    Background The aim of the study was to assess levels of somatic and mental health distress, well-being, AS WELL AS utilization of primary and specialist health care services among war-related widowed and non-widowed female civilian survivors of war. Methods 100 war-related widowed lone mothers and 106 non-widowed mothers who had experienced the Kosovo war ten years previously participated in the study. Measures of somatic, depressive, post-traumatic stress, anxiety, and grief complaints, subjective well-being, and utilization of health care services during the previous three months were used. Results Compared to non-widowed mothers, widowed lone mothers reported significantly higher levels of somatic, depressive, post-traumatic stress, and anxiety complaints. Further, they reported significantly lower levels of subjective well-being as composed of positive and negative affect and satisfaction with life. More than half of both widowed and non-widowed mothers reported utilization of health care services during the last three months, without significant differences between the groups. However, only three percent of widowed lone mothers and four percent of non-bereaved mothers reported utilization of mental health services during the last three months, despite high levels of mental health distress especially among widowed lone mothers. Among widowed lone mothers, severity of prolonged grief symptoms significantly predicted number of contacts of specialist health care use over and above sociodemographic variables, number of war-related events, and other psychopathology. Conclusion War-related widowed lone mothers suffer from elevated somatic and mental distress even a decade after the war. The tiny proportion of widowed lone mothers in use of mental health services can be seen as a reflection of lack of previous and current mental health services to meet mental health needs of this population.

    2010-01-01

    Emerging evidence implicates metabolic syndrome as a long-term cancer risk factor but also suggests that certain cancer therapies might increase patients' risk of developing metabolic syndrome secondary to cancer therapy. In particular, breast cancer and prostate cancer are driven in part by sex hormones; thus, treatment for both diseases is often based on hormone-modifying therapy. Androgen suppression therapy in men with prostate cancer is associated with dyslipidemia, increasing risk of cardiovascular disease, and insulin resistance. Anti-estrogen therapy in women with breast cancer can affect lipid profiles, cardiovascular risk, and liver function. As the number of cancer survivors continues to grow, treating physicians must be aware of the potential risks facing patients who have been treated with either androgen suppression therapy or anti-estrogen therapy so that early diagnosis and intervention can be achieved.

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome.

    Background Cardiac surgery with cardiopulmonary bypass (CPB) is a known risk factor for acute respiratory distress syndrome (ARDS). We aimed to analyze the treatment outcome in patients who required veno-venous extracorporeal membrane oxygenation (VV-ECMO) for postcardiotomy ARDS despite other rescue modalities. Methods We retrospectively reviewed the outcomes in 13 patients (mean age, 54.7±5.9 years) who received VV-ECMO support for refractory ARDS after cardiac surgery between March 2013 and February 2016 at Severance Hospital, Yonsei University (Seoul, Korea). Results At the start of VV-ECMO, the average lung injury score was 3.0±0.2, and the Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score was −4±1.1. Although 7 patients initiated VV-ECMO support within 24 h from operation, the remaining 6 started at a median of 8.5 days (range, 5−16 days). Nine (69.3%) patients were successfully weaned from VV-ECMO. After a median follow-up duration of 14.5 months (range, 1.0−33.0 months) for survivors, the 1-year overall survival was 58.6%±14.4%. The differences in the overall survival from VV-ECMO according to the RESP score risk classes were borderline significant (100% in class III, 50%±25% in class IV, and 20%±17.9% in class V; P=0.088). Conclusions VV-ECMO support can be a feasible rescue strategy for adult patients who develop refractory ARDS after a cardiac surgery. Additionally, the RESP score seems a valuable prognostic tool for post-ECMO survival outcome in this patient population as well. PMID:27499972

    Lung injury especially acute respiratory distress syndrome (ARDS) can be triggered by diverse stimuli, including fatty acids and microbes. ARDS affects thousands of people worldwide each year, presenting high mortality rate and having an economic impact. One of the hallmarks of lung injury is edema formation with alveoli flooding. Animal models are used to study lung injury. Oleic acid-induced lung injury is a widely used model resembling the human disease. The oleic acid has been linked to metabolic and inflammatory diseases; here we focus on lung injury. Firstly, we briefly discuss ARDS and secondly we address the mechanisms by which oleic acid triggers lung injury and inflammation. PMID:26640323

    Objectives In the Fluid and Catheter Treatment Trial (FACTT) of the National Institutes of Health Acute Respiratory Distress Syndrome Network, a conservative fluid protocol (FACTT Conservative) resulted in a lower cumulative fluid balance and better outcomes than a liberal fluid protocol (FACTT Liberal). Subsequent Acute Respiratory Distress Syndrome Network studies used a simplified conservative fluid protocol (FACTT Lite). The objective of this study was to compare the performance of FACTT Lite, FACTT Conservative, and FACTT Liberal protocols. Design Retrospective comparison of FACTT Lite, FACTT Conservative, and FACTT Liberal. Primary outcome was cumulative fluid balance over 7 days. Secondary outcomes were 60-day adjusted mortality and ventilator-free days through day 28. Safety outcomes were prevalence of acute kidney injury and new shock. Setting ICUs of Acute Respiratory Distress Syndrome Network participating hospitals. Patients Five hundred three subjects managed with FACTT Conservative, 497 subjects managed with FACTT Liberal, and 1,124 subjects managed with FACTT Lite. Interventions Fluid management by protocol. Measurements and Main Results Cumulative fluid balance was 1,918 ± 323 mL in FACTT Lite, −136 ±491 mL in FACTT Conservative, and 6,992 ± 502 mL in FACTT Liberal (p < 0.001). Mortality was not different between groups (24% in FACTT Lite, 25% in FACTT Conservative and Liberal, p = 0.84). Ventilator-free days in FACTT Lite (14.9 ±0.3) were equivalent to FACTT Conservative (14.6±0.5) (p = 0.61) and greater than in FACTT Liberal (12.1 ±0.5, p < 0.001 vs Lite). Acute kidney injury prevalence was 58% in FACTT Lite and 57% in FACTT Conservative (p = 0.72). Prevalence of new shock in FACTT Lite (9%) was lower than in FACTT Conservative (13%) (p = 0.007 vs Lite) and similar to FACTT Liberal (11%) (p = 0.18 vs Lite). Conclusions FACTT Lite had a greater cumulative fluid balance than FACTT Conservative but had equivalent clinical and safety outcomes

    Sporadic patients with acute respiratory distress syndrome (ARDS) caused by Mycoplasma pneumoniae have been reported. However, knowledge about the pathophysiology and pharmacological treatment of this condition is insufficient. Moreover, the pulmonary vascular permeability in ARDS related to M. pneumoniae infection has not been reported. We report a case of ARDS caused by Mycoplasma pneumoniae without elevated pulmonary vascular permeability, which was successfully treated using low-dose short-term hydrocortisone, suggesting that pulmonary infiltration in ARDS caused by Mycoplasma pneumoniae does not match the criteria of permeability edema observed in typical ARDS.

Clinical trials must have realistic sample sizes and meaningful end points and use the available observation and meta-analytical data to inform design. Biomarker-driven studies or defined ARDS subsets should be considered to categorize specific at-risk populations most likely to benefit from a new treatment. Innovations in clinical trial design should be pursued to improve the outlook for future interventional trials in ARDS.

    Physical and biochemical parameters of pulmonary surfactant (PS) were studied in 6-day-old rabbits with the respiratory distress syndrome (RDS) treated by benzonal and zixorin inductors. Surface-active characteristics of PS were impaired under conditions of RDS at the expense of deficiency of total phospholipids, specifically phosphatidylcholine (PC) and phosphatidylethanolamine (PEA). Treatment with benzonal and zixorin improved the surface-active characteristics of PS and increased the content of total phospholipids mainly at the expense of PC and PEA. PMID:11980138

    This observational cohort study examined the relationships between actual and perceived R/S change at 12 months post cancer diagnosis with depression, anxiety, and perceived growth 6 months later. Older adult military veteran cancer survivors (n = 111) completed self-report surveys at 6, 12, and 18 months post cancer diagnosis. Perceived R/S change was assessed at 12 months postdiagnosis with “Have your religious or spiritual beliefs changed as a result of your cancer” (more R/S, less R/S, other). Actual R/S change was assessed at 6 and 12 months postdiagnosis on a single item, “I have faith in God or a Higher Power” (no, somewhat, yes). A notable minority reported perceived (18.9%) and actual (14.4%) change. Greater perceived R/S change predicted more severe symptoms of depression and anxiety and greater perceived growth at 18 months postdiagnosis; perceived growth was positively associated with anxiety. Cancer survivors who report R/S changes may benefit from spiritual and/or psychological support. PMID:27453768

    The efficiency of a combined approach to the correction of clinical manifestations of non-specific distress syndrome was evaluated in patients with psychovegetative syndrome by comparing effects of phytoaeroionotherapy, graduated physical exercises, and soft tissue manual therapy in different combinations with simultaneous magnetopuncture therapy and without it. It was shown that above therapeutic modalities combined with magnetotherapy decreased the degree of asymmetry of both right and left heart meridians (by 60.5%) and interhemisphere asymmetry of blood flow in the system of internal carotid arteries (by 74.19%), reduced the tone of cerebral arterioles and veins (by 40.7% and 8.6% respectively), improved symptomes of depression and asthenia (by 23.2% and 63.9% respectively), increased mental performance quotient and activity indices (by 34.7% and 28.7% respectively). These changes were far less significant in the absence of by magnetopuncture therapy. PMID:19514296

    Objective The role of systemic corticosteroids in pathophysiology and treatment of acute respiratory distress syndrome is controversial. Use of prehospital systemic corticosteroid therapy may prevent the development of acute respiratory distress syndrome and improve hospital outcomes. Design This is a preplanned retrospective subgroup analysis of the prospectively identified cohort from a trial by the U.S. Critical Illness and Injury Trials Group designed to validate the Lung Injury Prediction Score. Setting Twenty-two acute care hospitals. Patients Five thousand eighty-nine patients with at least one risk factor for acute respiratory distress syndrome at the time of hospitalization. Intervention Propensity-based analysis of previously recorded data. Measurements and Main Results Three hundred sixty-four patients were on systemic corticosteroids. Prevalence of acute respiratory distress syndrome was 7.7% and 6.9% (odds ratio, 1.1 [95% CI, 0.8–1.7]; p = 0.54) for patients on systemic corticosteroid and not on systemic corticosteroids, respectively. A propensity for being on systemic corticosteroids was derived through logistic regression by using all available covariates. Subsequently, 354 patients (97%) on systemic corticosteroids were matched to 1,093 not on systemic corticosteroids by their propensity score for a total of 1,447 patients in the matched set. Adjusted risk for acute respiratory distress syndrome (odds ratio, 0.96 [95% CI, 0.54–1.38]), invasive ventilation (odds ratio, 0.84 [95% CI, 0.62–1.12]), and inhospital mortality (odds ratio, 0.97 [95% CI, 0.63–1.49]) was then calculated from the propensity-matched sample using conditional logistic regression model. No significant associations were present. Conclusions Prehospital use of systemic corticosteroids neither decreased the development of acute respiratory distress syndrome among patients hospitalized with at one least risk factor, nor affected the need for mechanical ventilation or hospital

    Acute interstitial pneumonia (AIP) is a term used for an idiopathic form of acute lung injury characterized clinically by acute respiratory failure with bilateral lung infiltrates and histologically by diffuse alveolar damage (DAD), a combination of findings previously known as the Hamman-Rich syndrome. This review aims to clarify the diagnostic criteria of AIP, its relationship with DAD and acute respiratory distress syndrome (ARDS), key etiologies that need to be excluded before making the diagnosis, and the salient clinical features. Cases that meet clinical and pathologic criteria for AIP overlap substantially with those that fulfill clinical criteria for ARDS. The main differences between AIP and ARDS are that AIP requires a histologic diagnosis of DAD and exclusion of known etiologies. AIP should also be distinguished from "acute exacerbation of IPF," a condition in which acute lung injury (usually DAD) supervenes on underlying usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF).

  12. Noninvasive ventilation for acute respiratory distress syndrome: the importance of ventilator settings

    Noninvasive ventilation (NIV) is commonly used to prevent endotracheal intubation in patients with acute respiratory distress syndrome (ARDS). Patients with hypoxemic acute respiratory failure who fail an NIV trial carry a worse prognosis as compared to those who succeed. Additional factors are also knowingly associated with worse outcomes: higher values of ICU severity score, presence of severe sepsis, and lower ratio of arterial oxygen tension to fraction of inspired oxygen. However, it is still unclear whether NIV failure is responsible for the worse prognosis or if it is merely a marker of the underlying disease severity. There is therefore an ongoing debate as to whether and which ARDS patients are good candidates to an NIV trial. In a recent paper published in JAMA, “Effect of Noninvasive Ventilation Delivered by Helmet vs. Face Mask on the Rate of Endotracheal Intubation in Patients with Acute Respiratory Distress Syndrome: A Randomized Clinical Trial”, Patel et al. evaluated ARDS patients submitted to NIV and drew attention to the importance of the NIV interface. We discussed their interesting findings focusing also on the ventilator settings and on the current barriers to lung protective ventilation in ARDS patients during NIV. PMID:27747041

    Neutrophils (PMNs) have been implicated in the pathogenesis of the adult respiratory distress syndrome. To further define their role, the authors studied the kinetics of In-111 labeled PMNs in a sheep model of acute pulmonary vascular injury. PMNs isolated by Percoll-plasma gradient centrifugation, and labeled with 500 uCi of In-111-oxine. Following i.v. reinfusion of the labeled PMNs, lung activity was monitored with the labeled PMNs, lung activity was monitored with a gamma camera. After a two hour baseline, pulmonary vascular injury secondary to intravascular coagulation was induced by the i.v. infusion of 100 units/kg of thrombin (n=5). Pulmonary time activity curves demonstrated increases in pulmonary PMN activity averaging 14% over baseline following thrombin infusion. A portion of the uptake was transient, lasting about 20 to 30 min., but PMN activity remained above baseline for the remainder of the study. Following the infusion of gamma thrombin, a form of thrombin unable to cleave fibrinogen, increased PMN uptake was not observed. Inhibition of fibrinolysis with tranaxemic acid, reduced the PMN response to thrombin to less than a 3% increase over baseline (n=2). The findings demonstrate that PMNs are involved in acute pulmonary vascular injury, and suggest a potential role for labeled PMNs in the clinical investigation of the adult respiratory distress syndrome.

    In a retrospective analysis the records of all (210) infants ventilated to treat the respiratory distress syndrome over three years were reviewed. A mortality of 19% was found. Intraventricular haemorrhage was associated than a significant increase in mortality in infants of less with 30 weeks' gestation (p less than 0.001) and was the commonest cause of death. Pneumothoraces developed in one third of babies regardless of gestational age but were significantly associated with an increase in mortality only in infants of 27-29 weeks' gestation. Patent ductus arteriosus was present in 31 infants and was commoner in babies of very low birth weight. The presence of a patent ductus arteriosus was not associated with decreased survival but was significantly related to an increased need for prolonged respiratory support (p less than 0.001). Thirty six infants developed chronic lung disease, three of whom died. Comparison with data from earlier studies indicated a steady improvement over the past decade in outcome for infants ventilated for the respiratory distress syndrome. PMID:3918687

    There are few reports from Japan on the analysis of fluids in survivors of body-packer syndrome. We analyzed the concentrations of stimulants in the serum, plasma and urine collected from three patients suspected of being body packers at immigration that were referred to hospitals between 2010 and 2011. The drugs were extracted with solid-phase columns and analyzed by gas chromatography-mass spectrometry (GC-MS). In all cases, wrapped, cylindrical packets of foreign bodies were detected in the intestinal tract on plain X-ray (X-P) and computed tomography (CT), and they were eventually removed surgically. In case 1, the patient presented with convulsions and tachycardia at admission to the hospital and one of the packets was found to have ruptured. In case 2, although the subject appeared to have an intestinal obstruction caused by the packets on the third day, he exhibited no symptoms on arrival and the packets did not appear to have ruptured. In case 3, the patient exhibited restlessness on the first day and one of the removed packets had ruptured. In all cases, methamphetamine (MA) and amphetamine (AP) were detected in serum, plasma and urine. In this study, we report the variation in MA and AP concentrations in survivors of body-packer syndrome. The serum and plasma concentrations of MA were high in subjects that exhibited symptoms of MA intoxication. MA and AP were also detected in the case in which the patient exhibited no symptoms of intoxication and the packets had not ruptured. These results suggest either that the stimulants may have seeped through the wrap of the packets, or that the subject had been abusing the drugs.

    A 30-year-old man and a 39-year-old woman, who was 28 weeks pregnant, were simultaneously poisoned by eating chocolate containing arsenic trioxide. They developed a picture of multiple organ failure peaking around the 8th to 10th day after ingestion, with the development of life-threatening adult respiratory distress syndrome (ARDS) in both patients. This rarely reported complication of arsenic poisoning was managed successfully by intubation and mechanical ventilation with positive end expiratory pressure in both patients. Hemodynamic and laboratory data are presented supporting the clinical course. Arsenic toxicity further resulted in intrauterine fetal death. The effects of severe arsenic poisoning leading to early multiple organ failure with ARDS as well as to protracted, debilitating polyneuropathy are discussed.

The patient's Typhidot test was positive for IgM antibodies. Her Widal test was negative, and blood culture and synovial fluid culture were sterile. She was started on ceftriaxone, to which her fever initially responded. However, after 4 days of treatment her disease course was complicated by relapse of fever and acute respiratory distress syndrome (ARDS). This settled with respiratory support and addition of azithromycin. Following recovery from ARDS and fever, her persistent knee arthritis responded to intra-articular methyl prednisolone instillation. PMID:25336548

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate. ARDS accompanied by AOSD has been rarely reported in the literature. In conclusion, in a patient with ARDS who does not respond to antibiotic treatment, the involvement of AOSD should be considered.

    The effect of route of delivery on incidence of respiratory distress syndrome (RDS) has been controversial. While some investigators have reported no difference in RDS rates in infants born by cesarean section as compared to vaginal delivery, others have shown a significant increase in risk for RDS among infants born by cesarean section. Data from the 297 patients comprising the placebo group in the recently completed collaborative study of antenatal steroid therapy in the prevention of neonatal RDS, were analyzed to determine the effect of mode of delivery on RDS. The results indicate that infants born by cesarean section without labor have a higher risk for neonatal RDS than infants born vaginally or by cesarean section after a trial of labor. PMID:2903080

    Ninety-eight insulin-dependent diabetic patients were cared for during 108 pregnancies following an ambulatory program aimed at close control of blood sugar levels. The incidence of respiratory distress syndrome (RDS) in these patients was not different from that in nondiabetic patients. Fetal pulmonary maturity seemed to progress at a normal rate as evidenced by an equal incidence of mature lecithin/sphingomyelin (L/S) ratios at various stages of gestation in diabetic and nondiabetic patients. There was no evidence that Class B and C diabetic patients have delayed fetal lung maturation or that Class E, F, and R patients have accelerated maturation. It is concluded that careful metabolic control of the pregnant diabetic patient results in a normal process of fetal pulmonary maturation without increased risk of RDS. PMID:474639

    2016-01-01

    Steroids have a plausible mechanism of action of reducing severity of lung disease in acute respiratory distress syndrome (ARDS) but have failed to show consistent benefits in patient-centered outcomes. Many studies have confounding from the likely presence of ventilator-induced lung injury and steroids may have shown benefit because administration minimized ongoing inflammation incited by injurious ventilator settings. If steroids have benefit, it is likely for specific populations that fall within the heterogeneous diagnosis of ARDS. Those pediatric patients with concurrent active asthma or reactive airway disease of prematurity, in addition to ARDS, are the most common group likely to derive benefit from steroids, but are poorly studied. With the information currently available, it does not appear that the typical adult or pediatric patient with ARDS derives benefit from steroids and steroids should not be given on a routine basis.

Case 2 occurred after the work of applying a rust preventative that included zinc powder, mainly using an airless compressor. Since both were working in a boathouse, without using protective equipment, the possible causes of Case 1 and 2 were inhalation exposure to zinc fumes and zinc powder, respectively. The two patients showed similar clinical courses, including favorable treatment outcomes, mimicking acute respiratory failure complicated by a metal fume fever. PMID:24930880

We detected enrichment for all targeted proteins approximately 3 h from the start of infusion of [5,5,5-(2)H(3)] leucine, secretion times that varied from 1.2 to 2.5 h, and half lives that ranged between 10 and 21 h. Complement factor B, a component of the alternative pathway of complement activation, had an approximately twofold-longer half-life than the other three proteins. In addition, the kinetics of mature and carboxy-terminal tryptic peptides from the same protein (surfactant protein B) were not statistically different (p = 0.49).

    The aim of this study was to evaluate the effects of inhaled nitric oxide (iNO) therapy on oxygenation and mortality in children with acute respiratory distress syndrome (ARDS). Thirty-three children with ARDS and an arterial SatO2 <88% despite mechanical ventilation were analyzed. Patients in the iNO group were prospectively enrolled and treated with conventional therapy plus iNO. The control group consisted of retrospectively analyzed patients treated only with conventional therapy. A significant increase in PaO2/FiO2 ratio (25.6%) and decrease in oxygenation index (19.5%) was observed after 4 h of iNO treatment, when compared to baseline values. A positive response to iNO was detected in 69% of patients, and there was no difference between pulmonary and extrapulmonary ARDS. There was no difference in mortality and duration of mechanical ventilation between iNO and control group. PMID:22885439

For the better understanding of the pathomechanism of the disease in addition to the standard methods, first of all ultrastructural alterations were studied. Two phases of the morphologic alterations could be distinguished, the phase of the destruction and the phase of the repair. These two processes are not sharply distinguishable. Genesis of the characteristic histological alterations (damage to the epithelial and endothelial cells, formation of hyaline membranes, microcoagulation, proliferation of the type II pneumocytes and fibroblasts, fibrosis) is discussed, with regard to the data of the literature.

It highlights the historical and present-day data on the efficiency of extracorporeal membrane hemoxygenation, high-frequency ventilation, surfactant and inhaled nitric oxide therapy, and prone ventilation. The examinations have shown that ventilation in the prone position and extracorporeal membrane hemoxygenation not only improve gas exchange, but have a positive prognostic impact. The use of inhaled nitric oxide and surfactant achieves improved oxygenation for a while, but has no substantial effect on prognosis. The place of high-frequency oscillatory ventilation in the treatment of patients with ARDS has not been fully determined as some examinations have indicated a positive prognostic impact and other examinations have shown none or a negative impact.

After ruling out the most common causes of pulmonary infiltration in this type of patient and one week of broad spectrum antibiotics and steroids therapy, we proposed leukemic pulmonary infiltration as etiological diagnosis. Despite using a protective ventilatory strategy, recruitment maneuvers, prone position and high frequency oscillatory ventilation, her gas exchange became worse. Under this condition we used a Pumpless-Extracorporeal life assist (PELA) and begun chemotherapy. The method, arterial blood gases, hemodynamic parameters and ventilatory mechanics before and after its use are described. The patient remained on P-ELA for nine days; one week later she was extubated and ten days after she was discharged from the Intensive Care Unit the patient left the hospital in good health condition.

    Eleven patients with suspected adult respiratory distress syndrome (ARDS) and five control patients were studied using a computerized gamma imaging and analysis technique and 99mTc-labeled human serum albumin. The heart and right lung were imaged, lung:heart ratio was plotted vs. time, and a linear regression was fitted to the data points displayed. The slope of this fit was termed the ''slope index.'' An index value of 2 standard deviations greater than the control mean was considered positive. Radiographs from the six positive studies revealed typical diffuse air-space disease. Radiographs from two of the five negative studies demonstrated air-space consolidation. Both of these patients had elevated pulmonary capillary wedge pressure, cardiomegaly, and clinical course consistent with cardiogenic pulmonary edema. These preliminary data demonstrated a good correlation between positive slope index and clinical ARDS.

    Two methods for predicting adult respiratory distress syndrome (ARDS) were evaluated prospectively in a group of 81 multitrauma and sepsis patients considered at clinical high risk. A popular ARDS risk-scoring method, employing discriminant analysis equations (weighted risk criteria and oxygenation characteristics), yielded a predictive accuracy of 59% and a false-negative rate of 22%. Pulmonary alveolar-capillary permeability (PACP) was determined with a radioaerosol lung-scan technique in 23 of these 81 patients, representing a statistically similar subgroup. Lung scanning achieved a predictive accuracy of 71% (after excluding patients with unilateral pulmonary contusion) and gave no false-negatives. We propose a combination of clinical risk identification and functional determination of PACP to assess a patient's risk of developing ARDS.

    The acute respiratory distress syndrome (ARDS) is a common cause of acute respiratory failure, and is associated with substantial mortality and morbidity. Dozens of clinical trials targeting ARDS have failed, with no drug specifically targeting lung injury in widespread clinical use. Thus, the need for drug development in ARDS is great. Targeted proteomic studies in ARDS have identified many key pathways in the disease, including inflammation, epithelial injury, endothelial injury or activation, and disordered coagulation and repair. Recent studies reveal the potential for proteomic changes to identify novel subphenotypes of ARDS patients who may be most likely to respond to therapy and could thus be targeted for enrollment in clinical trials. Nontargeted studies of proteomics in ARDS are just beginning and have the potential to identify novel drug targets and key pathways in the disease. Proteomics will play an important role in phenotyping of patients and developing novel therapies for ARDS in the future. PMID:27031735

In the past few years, in addition to chest X-ray and lung computed tomography, newer functional lung imaging techniques, such as lung ultrasound, positron emission tomography, electrical impedance tomography and magnetic resonance, have been gaining a role as diagnostic tools to optimize lung assessment and ventilator management in ARDS patients. Here we provide an updated clinical review of lung imaging in ARDS over the past few years to offer an overview of the literature on the available imaging techniques from a clinical perspective.

    We report a case of a female patient of 47 years old who presents in a state of septic shock with acute insufficient respiratory complicated with syndrome of acute respiratory distress, together with a list of abdominal pain and polyarthralgia too. In her case of medical history, it is retained that she has had a intra-uterine device since 6 years without medical follow up. The initial thoraco-abdomino-pelvic scan shows a left ovarian vein thrombosis, as well as the opaqueness alveolus diffused interstitiel bilaterally and an aspect of ileitis. The IUD is taken off because of sudden occuring of purulent leucorrhoea. This results in a clinical and paraclinical improvement, whereas aminopenicillin was administered to the patient since 1 week. The microbiological blood test allows to put in evidence Fusobacterium necrophorum found in a blood culture and is sensitive to the amoxicilline-acide clavulanique and metronidazole. Isolation of this bacteria, classically found in Lemierre's syndrome, allowed to explain the multilfocalization of the symtoms and the list of pain. The whole concerns about a variant of Lemierre's syndrom: a state of septic shock secondary then caused by the anaerobic Gram negative bacilli, which is a commensal bacteria of the female genital tractus, complicated of septic emboli typical.

    Objective Cigarette smoke exposure has recently been found to be associated with increased susceptibility to trauma- and transfusion-associated acute respiratory distress syndrome (ARDS). We sought to determine 1) the prevalence of cigarette smoke exposure in a diverse multi-center sample of ARDS patients, and 2) whether cigarette smoke exposure is associated with severity of lung injury and mortality in ARDS. Design Analysis of the Albuterol for the Treatment of ALI (ALTA) and Omega ARDS Network studies. Setting Acute Respiratory Distress Syndrome Network hospitals. Patients Three hundred eighty one patients with ARDS. Interventions None. Measurements NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol), a validated tobacco-specific marker, was measured in urine samples from subjects enrolled in two NHLBI ARDS Network randomized controlled trials. Main Results Urine NNAL levels were consistent with active smoking in 36% of ARDS patients and with passive smoking in 41% of nonsmokers (vs 20% and 40% in general population, respectively). Patients with NNAL levels in the active smoking range were younger and had a higher prevalence of alcohol misuse, fewer comorbidities, lower severity of illness, and less septic shock at enrollment compared to patients with undetectable NNAL levels. Despite this lower severity of illness, the severity of lung injury did not significantly differ based on biomarker-determined smoking status. Cigarette smoke exposure was not significantly associated with death after adjusting for differences in age, alcohol use, comorbidities, and severity of illness. Conclusions In this first multicenter study of biomarker-determined cigarette smoke exposure in ARDS patients, we found that active cigarette smoke exposure was significantly more prevalent among ARDS patients compared to population averages. Despite their younger age, better overall health, and lower severity of illness, smokers by NNAL had similar severity of lung injury as patients with

    The influenza H1N1 epidemics in 2009 led a substantial number of people to develop severe acute respiratory distress syndrome and refractory hypoxemia. In these patients, extracorporeal membrane oxygenation was used as rescue oxygenation therapy. Several randomized clinical trials and observational studies suggested that extracorporeal membrane oxygenation associated with protective mechanical ventilation could improve outcome, but its efficacy remains uncertain. Organized by the Société de Réanimation de Langue Française (SRLF) in conjunction with the Société Française d’Anesthésie et de Réanimation (SFAR), the Société de Pneumologie de Langue Française (SPLF), the Groupe Francophone de Réanimation et d’Urgences Pédiatriques (GFRUP), the Société Française de Perfusion (SOFRAPERF), the Société Française de Chirurgie Thoracique et Cardiovasculaire (SFCTV) et the Sociedad Española de Medecina Intensiva Critica y Unidades Coronarias (SEMICYUC), a Consensus Conference was held in December 2013 and a jury of 13 members wrote 65 recommendations to answer the five following questions regarding the place of extracorporeal life support for patients with acute respiratory distress syndrome: 1) What are the available techniques?; 2) Which patients could benefit from extracorporeal life support?; 3) How to perform extracorporeal life support?; 4) How and when to stop extracorporeal life support?; 5) Which organization should be recommended? To write the recommendations, evidence-based medicine (GRADE method), expert panel opinions, and shared decisions taken by all the thirteen members of the jury of the Consensus Conference were taken into account.

    This summary of the American Cancer Society Prostate Cancer Survivorship Care Guidelines targets primary care physicians who coordinate care of prostate cancer survivors with subspecialists. Prostate cancer survivors should undergo prostate-specific antigen screening every six to 12 months and digital rectal examination annually. Surveillance of patients who choose watchful waiting for their prostate cancer should be conducted by a subspecialist. Any hematuria or rectal bleeding must be thoroughly evaluated. Prostate cancer survivors should be screened regularly for urinary incontinence and sexual dysfunction. Patients with predominant urge incontinence symptoms, which can occur after surgical and radiation treatments, may benefit from an anticholinergic agent. If there is difficulty with bladder emptying, a trial of an alpha blocker may be considered. A phosphodiesterase type 5 inhibitor can effectively treat sexual dysfunction following treatment for prostate cancer. Osteoporosis screening should occur before initiation of androgen deprivation therapy, and patients treated with androgen deprivation therapy should be monitored for anemia, metabolic syndrome, and vasomotor symptoms. Healthy lifestyle choices should be encouraged, including weight management, regular physical activity, proper nutrition, and smoking cessation. Primary care physicians should be vigilant for psychosocial distress, including depression, among prostate cancer survivors, as well as the potential impact of this distress on patients' family members and partners.

    The authors sought to evaluate the pathogenetic and prognostic role of a procoagulant and hypofibrinolytic state in the adult respiratory distress syndrome (ARDS). Twenty-two consecutive patients admitted to the intensive care unit (ICU) for respiratory monitoring (n = 2) or mechanical ventilation (n = 20) were studied, of whom 13 had ARDS and 9 were at risk for the syndrome. Plasma levels of thrombin-antithrombin III complexes (TAT), the plasmin-alpha2-antiplasmin complexes (PAP), tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor type 1 (PAI-1) were measured within 48 h after admission, together with respiratory variables allowing computation of the lung injury score (LIS), and pulmonary microvascular permeability [67Gallium-transferrin pulmonary leak index (PLI)], as measures of pulmonary dysfunction. Blood was also sampled 6-hourly until 2 days after admission. The LIS and PLI were higher in ARDS than at risk patients, in the presence of similar systemic morbidity and mortality. TAT complexes were elevated in a minority of patients of both groups, whereas the PAP, tPA and PAI levels were elevated above normal in the majority of ARDS and at risk patients, but groups did not differ. Neither circulating coagulation nor fibrinolysis variables correlated to either LIS or PLI. Furthermore, the course of haemostatic variables did not relate to outcome. These data indicate that systemic activation of coagulation and impaired fibrinolysis do not play a major role in ARDS development and outcome in patients with acute lung injury.

    Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a life-threatening form of respiratory failure that affects a heterogeneous population of critically ill patients. Although overall mortality appears to be decreasing in recent years due to improvements in supportive care, there are presently no proven, effective pharmacological therapies to treat ARDS and prevent its associated complications. The most common cause of death in ARDS is not hypoxemia or pulmonary failure, but rather multiple organ dysfunction syndrome (MODS), suggesting that improving survival in patients with ARDS may be linked to decreasing the incidence or severity of MODS. The key to developing novel treatments depends, in part, on identifying and understanding the mechanisms by which ARDS leads to MODS, although the heterogeneity and complexity of this disorder certainly poses a challenge to investigators. Novel therapies in development for treatment of ALI/ARDS include exogenous surfactant, therapies aimed at modulating neutrophil activity, such as prostaglandin and complement inhibitors, and treatments targeting earlier resolution of ARDS, such as beta-agonists and granulocyte macrophage colony-stimulating factor. From a clinical perspective, identifying subpopulations of patients most likely to benefit from a particular therapy and recognising the appropriate stage of illness in which to initiate treatment could potentially lead to better outcomes in the short term.

    Acute respiratory distress syndrome (ARDS) is a syndrome with heterogeneous underlying pathological processes. It represents a common clinical problem in intensive care unit patients and it is characterized by high mortality. The mainstay of treatment for ARDS is lung protective ventilation with low tidal volumes and positive end-expiratory pressure sufficient for alveolar recruitment. Prone positioning is a supplementary strategy available in managing patients with ARDS. It was first described 40 years ago and it proves to be in alignment with two major ARDS pathophysiological lung models; the “sponge lung” - and the “shape matching” -model. Current evidence strongly supports that prone positioning has beneficial effects on gas exchange, respiratory mechanics, lung protection and hemodynamics as it redistributes transpulmonary pressure, stress and strain throughout the lung and unloads the right ventricle. The factors that individually influence the time course of alveolar recruitment and the improvement in oxygenation during prone positioning have not been well characterized. Although patients’ response to prone positioning is quite variable and hard to predict, large randomized trials and recent meta-analyses show that prone position in conjunction with a lung-protective strategy, when performed early and in sufficient duration, may improve survival in patients with ARDS. This pathophysiology-based review and recent clinical evidence strongly support the use of prone positioning in the early management of severe ARDS systematically and not as a rescue maneuver or a last-ditch effort.

    Few studies have been performed on noninvasive ventilation (NIV) to treat hypoxic acute respiratory failure in patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). The outcomes of these patients, for whom endotracheal intubation is not mandatory, depend on the degree of hypoxia, the presence of comorbidities and complications, and their illness severity. The use of NIV as an alternative to invasive ventilation in severely hypoxemic patients with ARDS (ie, P(aO(2))/F(IO(2)) < 200) is not generally advisable and should be limited to hemodynamically stable patients who can be closely monitored in an intensive care unit by highly skilled staff. Early NIV application may be extremely helpful in immunocompromised patients with pulmonary infiltrates, in whom intubation dramatically increases the risk of infection, pneumonia, and death. The use of NIV in patients with severe acute respiratory syndrome and other airborne diseases has generated debate, despite encouraging clinical results, mainly because of safety issues. Overall, the high rate of NIV failure suggests a cautious approach to NIV use in patients with ALI/ARDS, including early initiation, intensive monitoring, and prompt intubation if signs of NIV failure emerge.

    Acute respiratory distress syndrome (ARDS) is the most severe form of respiratory failure. Theoretically, any acute lung condition can lead to ARDS, but only a small percentage of individuals actually develop the disease. On this basis, genetic factors have been implicated in the risk of developing ARDS. Based on the pathophysiology of this disease, many candidate genes have been evaluated as potential modifiers in patient, as well as in animal models, of ARDS. Recent experimental data and clinical studies suggest that variations of genes involved in key processes of tissue, cellular and molecular lung damage may influence susceptibility and prognosis of ARDS. However, the pathogenesis of pediatric ARDS is complex, and therefore, it can be expected that many genes might contribute. Genetic variations such as single nucleotide polymorphisms and copy-number variations are likely associated with susceptibility to ARDS in children with primary lung injury. Genome-wide association (GWA) studies can objectively examine these variations, and help identify important new genes and pathogenetic pathways for future analysis. This approach might also have diagnostic and therapeutic implications, such as predicting patient risk or developing a personalized therapeutic approach to this serious syndrome.

    Data on metabolic syndrome (MS) in survivors of childhood acute lymphoblastic leukemia (ALL) from developing countries are lacking. The purpose of this single-center, uncontrolled, observational study was to assess the frequency of MS in our survivors. The survivors of ALL ≤15 years at diagnosis, who had completed therapy ≥2 years earlier, were enrolled. Anthropometric measurements (weight, height, waist circumference), biochemistry (glucose, insulin, triglycerides, high-density lipoprotein [HDL], thyroid function tests, C-reactive protein [CRP], magnesium), measurement of blood pressure, and Tanner staging were performed. MS was defined by International Diabetes Federation (IDF) and the National Cholesterol Education Program Third Adult Treatment Panel guidelines (NCEP ATP III) criteria, modified by Cook et al. (Arch Pediatr Adolesc Med. 2003;157:821-827) and Ford et al. (Diabetes Care. 2005;28:878-881). The median age of 76 survivors was 11.9 years (interquartile range [IQR]: 9.6-13.5). Twenty-four (32%) survivors were obese or overweight. The prevalence of insulin resistance (17%), hypertension (7%), hypertriglyceridemia (20%), and low HDL (37%) was comparable to the prevalence in children/adolescents in historical population-based studies from India. The prevalence of MS ranged from 1.3% to 5.2%, as per different defining criteria. Cranial radiotherapy, age at diagnosis, sex, or socioeconomic status were not risk factors for MS. The prevalence of MS in survivors of childhood ALL, at a median duration of 3 years from completion of chemotherapy, was comparable to the reference population. The prevalence of being obese or overweight was, however, greater than historical controls. PMID:26984439

    Our purpose was to determine the prevalence and features of metabolic syndrome (MS) in a series of long-term hematopoietic stem cell transplantation (HSCT) survivors. We assessed the clinical, metabolic and endocrinological data, and plasma TNF, leptin, resistin and adiponectin levels relating to 85 HSCT recipients. MS was diagnosed on the basis of the National Cholesterol Education Program-Adult Treatment Panel III criteria. Its prevalence was compared with that observed in an Italian population, and its relationship with the clinical and laboratory parameters was assessed univariately and multivariately. Twenty-nine HSCT recipients had MS instead of the 12.8 expected (P<0.0001), with hypertriglyceridemia being the most common feature. Univariate analysis indicated that high insulin and leptin levels, low-adiponectin levels and hypogonadism were significantly related to a diagnosis of MS; multivariate analysis indicated plasma leptin, insulin resistance, age and hypogonadism. We conclude that HSCT recipients are at increased risk of a form of MS that has particular clinical features. Plasma leptin levels are independently related to MS, thus suggesting that leptin resistance may play a role as a pathogenetic clue, as in other conditions in which MS occurs as a secondary phenomenon. MS deserves consideration as a life-threatening complication in patients who are probably cured of their underlying disease.

Follow-up examination in both children showed steady neurologic recovery, but five months following discharge from their acute illness, profound hearing loss was diagnosed in both children. A review of the literature is reported and the hypothesis that combined aminoglycoside antibiotic and loop diuretic therapy caused the hearing loss is presented. Recommendation is made for audiologic assessment within six months of recovery from critical illness of pediatric patients in whom therapy has included loop diuretic and aminoglycoside antibiotic therapy.

    Acute respiratory distress syndrome (ARDS) increases mortality in patients with multiorgan dysfunction syndrome (MODS). This study evaluates the feasibility of intrapleural steroid instillation (IPSI) in patients with ARDS and MODS unresponsive to conventional extracorporeal membrane oxygenation (ECMO). Ninety-two of 467 patients who underwent ECMO between 2005 and 2009 had ARDS, and 30 consecutive adult patients of these 92 patients with severe ARDS and MODS were retrospectively analyzed in this study. Nine of these 30 patients, who did not respond to therapy and whose condition deteriorated, were managed with IPSI. All patients met the inclusion criteria of hemodynamic instability with high catecholamine infusion requirement and 100% oxygen demand in ventilation and ECMO flow. On initial diagnosis of ARDS, no differences in prognostic scorings were observed in patients who underwent conventional treatment (n = 21) and those who underwent IPSI (n = 9). Blood oxygenation, tidal volume, changing in chest radiographic findings, and survival rates were analyzed. The primary outcome was survival until discharge from the hospital. Pulmonary radiographic appearance improved after 3 days of IPSI treatment (P = 0.008); the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen also increased significantly after 5 days of IPSI treatment (P = 0.028). Moreover, the 28-day mortality rate (P = 0.017), 60-day mortality rate (P = 0.003), and survival rate (78% vs. 19%; P = 0.003) significantly improved in patients undergoing IPSI, which therefore appears to be an easily implemented and highly effective treatment for patients with severe ARDS in combination with MODS, particularly in patients who fail to respond to conventional treatment.

    A 43-year-old man began having malaise, chills, and fever 12 hours after cutting a galvanized steel grating with an acetylene torch at work. Over the next 72 hours, his symptoms persisted and became worse with progressive shortness of breath. He was admitted to the hospital and begun on antibiotics and steroids. The next day his condition had deteriorated to the point that he had to be intubated. Chest x-ray film and computed tomography showed patchy and interstitial infiltration bilaterally, consistent with acute respiratory distress syndrome. Open lung biopsy showed focal mild interstitial pneumonia. Multiple laboratory studies were negative for an infectious or an immune process. The patient remained on mechanical ventilation for 10 days and was discharged from the hospital 2 days after extubation. He continued to improve, with minimal symptoms and a return to normal activity levels several months after the incident with no continued treatment. Re-creation of his exposure was done under controlled circumstances, with air sampling revealing elevated air levels for cadmium and zinc and borderline levels of arsenic, manganese, lead, and iron.

    2016-01-01

    There is new and growing experience with venovenous extracorporeal life support (VV ECLS) for neonatal and pediatric patients with single-ventricle physiology and acute respiratory distress syndrome (ARDS). Outcomes in this population have been defined but could be improved; survival rates in single-ventricle patients on VV ECLS for respiratory failure are slightly higher than those in single-ventricle patients on venoarterial ECLS for cardiac failure (48 vs. 32–43%), but are lower than in patients with biventricular anatomy (58–74%). To that end, special consideration is necessary for patients with single-ventricle physiology who require VV ECLS for ARDS. Specifically, ARDS disrupts the balance between pulmonary and systemic blood flow through dynamic alterations in cardiopulmonary mechanics. This complexity impacts how to run the VV ECLS circuit and the transition back to conventional support. Furthermore, these patients have a complicated coagulation profile. Both venous and arterial thrombi carry marked risk in single-ventricle patients due to the vulnerability of the pulmonary, coronary, and cerebral circulations. Finally, single-ventricle palliation requires the preservation of low resistance across the pulmonary circulation, unobstructed venous return, and optimal cardiac performance including valve function. As such, the proper timing as well as the particular conduct of ECLS might differ between this population and patients without single-ventricle physiology. The goal of this review is to summarize the current state of knowledge of VV ECLS in the single-ventricle population in the context of these special considerations. PMID:27446889

    2015-11-01

    Acute respiratory distress syndrome (ARDS) represents a serious problem in critically ill patients and is associated with in-hospital mortality rates of 33%-52%. Recruitment maneuvers (RMs) are a simple, low-cost, feasible intervention that can be performed at the bedside in patients with ARDS. RMs are characterized by the application of airway pressure to increase transpulmonary pressure transiently. Once non-aerated lung units are reopened, improvements are observed in respiratory system mechanics, alveolar reaeration on computed tomography, and improvements in gas exchange (functional recruitment). However, the reopening process could lead to vascular compression, which can be associated with overinflation, and gas exchange may not improve as expected (anatomical recruitment). The purpose of this review was to discuss the effects of different RM strategies - sustained inflation, intermittent sighs, and stepwise increases of positive end-expiratory pressure (PEEP) and/or airway inspiratory pressure - on the following parameters: hemodynamics, oxygenation, barotrauma episodes, and lung recruitability through physiological variables and imaging techniques. RMs and PEEP titration are interdependent events for the success of ventilatory management. PEEP should be adjusted on the basis of respiratory system mechanics and oxygenation. Recent systematic reviews and meta-analyses suggest that RMs are associated with lower mortality in patients with ARDS. However, the optimal RM method (i.e., that providing the best balance of benefit and harm) and the effects of RMs on clinical outcome are still under discussion, and further evidence is needed.

    Supporting patients with acute respiratory distress syndrome (ARDS), using a protective mechanical ventilation strategy characterized by low tidal volume and limitation of positive end-expiratory pressure (PEEP) is a standard practice in the intensive care unit. However, these strategies can promote lung de-recruitment, leading to the cyclic closing and reopening of collapsed alveoli and small airways. Recruitment maneuvers (RM) can be used to augment other methods, like positive end-expiratory pressure and positioning, to improve aerated lung volume. Clinical practice varies widely, and the optimal method and patient selection for recruitment maneuvers have not been determined, considerable uncertainty remaining regarding the appropriateness of RM. This review aims to discuss recent findings about the available types of RM, and compare the effectiveness, indications and adverse effects among them, as well as their impact on morbidity and mortality in ARDS patients. Recent developments include experimental and clinical evidence that a stepwise extended recruitment maneuver may cause an improvement in aerated lung volume and decrease the biological impact seen with the traditionally used sustained inflation, with less adverse effects. Prone positioning can reduce mortality in severe ARDS patients and may be an useful adjunct to recruitment maneuvers and advanced ventilatory strategies, such noisy ventilation and BIVENT, which have been useful in providing lung recruitment.

    Total ginsenosides synergize with ulinastatin (UTI) against septic acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We randomly divided 80 cases of severe sepsis-induced ALI and ARDS into a UTI group and a ginsenosides (GS)+UTI group. Continuous electrocardiac monitoring of pulse, respiratory rate, blood pressure, and heart rate; invasive hemodynamic monitoring; ventilator-assisted breathing and circulation support; and anti-infection as well as UTI treatment were given in the UTI group with GS treatment added for 7 consecutive days in the GS+UTI group. The indicators of pulmonary vascular permeability, pulmonary circulation, blood gases, and hemodynamics as well as APACHE II and ALI scores were detected on days 1, 3, and 7. The ALI score in the GS+UTI group was significantly decreased (P < 0.05) compared with that of the UTI group, and the indicators of pulmonary capillary permeability such as pulmonary vascular permeability index, extravascular lung water index, and oxygenation index, in the GS+UTI group improved significantly more than that of the UTI group. The indicators of hemodynamics and pulmonary circulation such as cardiac index, intrathoracic blood volume index, and central venous pressure improved significantly (P < 0.05), and the APACHE II score in the GS+UTI group was lower than that of the UTI group. GS can effectively collaborate with UTI against ALI and/or ARDS. PMID:26261640

    2004-12-01

    The acute respiratory distress syndrome (ARDS) is the most serious form of acute hypoxic respiratory failure. ARDS represents the expression of an acute, diffuse, inflammatory process in the lungs consequent to a variety of infectious and noninfectious conditions. It is characterized pathologically by damage to pulmonary epithelial and endothelial cells, with subsequent alveolar-capillary leak and exudative pulmonary edema. The main clinical features of ARDS include rapid onset of dyspnea, severe defects in gas exchange, and imaging studies demonstrating diffuse pulmonary infiltrates. The role of nutrition in the management of ARDS has traditionally been supportive. Recent research has demonstrated the potential of certain dietary oils (eg, fish oil, borage oil) to modulate pulmonary inflammation, thereby improving lung compliance and oxygenation, and reducing time on mechanical ventilation. This article reviews the alterations in the immune response that underlie ARDS, discusses the physiology of dietary oils as immunonutrients, summarizes animal and human studies that explore the therapeutic effects of dietary oils, and provides clinical recommendations for their use.

    Sepsis and the acute respiratory distress syndrome (ARDS) are major causes of mortality without targeted therapies. Although many experimental and clinical observations have implicated gut microbiota in the pathogenesis of these diseases, culture-based studies have failed to demonstrate translocation of bacteria to the lungs in critically ill patients. Here, we report culture-independent evidence that the lung microbiome is enriched with gut bacteria both in a murine model of sepsis and in humans with established ARDS. Following experimental sepsis, lung communities were dominated by viable gut-associated bacteria. Ecological analysis identified the lower gastrointestinal tract, rather than the upper respiratory tract, as the likely source community of post-sepsis lung bacteria. In bronchoalveolar lavage fluid from humans with ARDS, gut-specific bacteria (Bacteroides spp.) were common and abundant, undetected by culture and correlated with the intensity of systemic inflammation. Alveolar TNF-α, a key mediator of alveolar inflammation in ARDS, was significantly correlated with altered lung microbiota. Our results demonstrate that the lung microbiome is enriched with gut-associated bacteria in sepsis and ARDS, potentially representing a shared mechanism of pathogenesis in these common and lethal diseases.

    Samples of amniotic fluid from 514 non-diabetic and 69 diabetic patients were analyzed for phospholipid content. Results were correlated with incidence of respiratory distress syndrome (RDS) in the neonate. The incidence of RDS was 4.5% among diabetics and 5.3% among non-diabetics. In the presence of phosphatidylglycerol (PG), no infant developed RDS while in the absence of PG the incidence of RDS was 16.7% and 14.4%, respectively. In the presence of a mature lecithin/sphingomyelin (L/S) ratio the respective incidence of RDS was 1.6 and 1.8, while with an immature L/S ratio the incidence of RDS was 28.6% and 29%. The incidence of RDS after 37 weeks gestation was 0% among diabetics and 0.6% among non-diabetics. We conclude that amniotic fluid phospholipids are equally predictive of risk for RDS in diabetics as among non-diabetic patients. We suggest that in patients with accurate gestational dating, amniotic fluid analysis for phospholipids might not be necessary to establish fetal lung maturity. PMID:2572479

    Introduction: Acute respiratory distress syndrome (ARDS) is characterized by acute respiratory failure and is associated with wide range of clinical disorders. Controversy prevails over the pharmacological intervention in this disease. The aim of the study was to observe the prescribing pattern of drugs in patients with ARDS managed at a tertiary care hospital. Materials and Methods: This observational study was conducted at tertiary care hospital in India. Data of patients admitted from January 2010 to December 2012 was collected. Patients aged more than 18 years admitted in ICU, who were diagnosed to have ARDS during the study period, were included. A total of 150 patients of ARDS were selected. Data was collected as per the pre designed proforma and it included patients’ age, gender, clinical disorders precipitating ARDS, prescribing pattern of drugs and outcome. The data of the subjects was collected till discharge from hospital or death. Results: Infection was the cause of ARDS in 81.3% (n=122) of subjects. Antibiotics were prescribed in all the subjects and beta-lactams were prescribed in 97.3% (n=146). 41.3% (n=62) were prescribed corticosteroids, 39.3% (n=59) diuretics and 89.3% (n=134) intravenous fluids. Conclusion: The outcome of patients on different pharmacological treatment did not show any statistically significant difference. PMID:25859465

    The respiratory distress syndrome (RDS) occurs in 14% of premature infants and is twice as common and twice as lethal in males as in females. Recent work suggests that, during the intrauterine period a disturbance in nutrition of the lung resulting from fetal pulmonary vascular constriction results in alveolar-cell damage and a decrease in pulmonary surface activity with resultant atelectasis. Data on respiratory work levels, oxygen consumption and arterial oxygen tension suggest that there is an oxygen debt in the acute stage of the disease. Such data have further clarified the pathogenesis of the metabolic and respiratory components of the acidosis and the secondary effects thereof. In prevention, prophylaxis of prematurity is of major importance. A program of treatment designed to combat the various aspects of the pathophysiological disturbances is described in the form of a case profile. Modern methods of observation, biochemical control and treatment, as well as the necessity for critical evaluation, suggest that infants with RDS are best cared for in special centres. PMID:14339292

    BACKGROUND: Early postnatal use of dexamethasone in infants with respiratory distress syndrome (RDS) has been shown effectively to improve pulmonary status and to allow early weaning off mechanical ventilation. However, the mechanisms to explain the beneficial effects of dexamethasone in ventilatory dependent preterm infants remain unclear. METHODS: A double blind, placebo controlled study was performed to determine the change in pulmonary ventilation of premature infants with RDS as a result of dexamethasone treatment, and to evaluate the effect of dexamethasone on the levels of surfactant-associated proteins A (SP-A) and D (SP-D) in the tracheal fluid from 34 premature infants with RDS and 29 control subjects. RESULTS: Dexamethasone treatment decreased fractional inspired oxygen concentration (FIO2), arterial carbon dioxide tension (PCO2), mean airway pressure (MAP), and facilitated successful weaning from mechanical ventilation. SP-A concentrations in the tracheal aspirates were increased at days 7 and 14, and SP-D concentrations were increased during the period from days 3 to 14 in the dexamethasone treated group compared with the control group. However, albumin levels in the tracheal aspirate samples were decreased after dexamethasone treatment over the period from days 3 to 14. There was an inverse correlation between PCO2 values and SP-A concentrations. CONCLUSIONS: These results suggest that early use of dexamethasone can improve pulmonary status and also increase SP-A and SP-D levels in the tracheal fluid in premature infants with RDS.

    A 24-year-old woman developed adult respiratory distress syndrome (ARDS) after near-drowning due to attempted suicide. Conventional mechanical ventilation together with prone positioning and inhaled nitric oxide could not provide sufficient oxygenation. Surface tension data (gamma min = 27 dyn/cm, stability index = 0.341) from a lavage sample supported the hypothesis that the surfactant function of this patient was drastically reduced due to a washout effect by aspiration of fresh water. Porcine surfactant (Curosurf, 50 mg/kg for each lung) was instilled via fibreoptic bronchoscope. The partial arterial carbon dioxide pressure (paCO2) and fraction of inspired oxygen (FiO2) ratio as well as shunt fraction (Qs/Qt) improved impressively. When respiratory situation deteriorated again, surfactant application was repeated. Altogether, six bolus instillations of surfactant (total dose 300 mg/kg = 18,000 mg) were administered until the respiratory situation had stabilized and oxygenation could be maintained by conventional mechanical ventilation. The radiological findings did not show substantial amelioration. The patient developed septic shock and died 12 days after admission. Surfactant application apparently led to a significant improvement of the respiratory function. However, the outcome could not be influenced positively. The high cost of surfactant therapy prevents the more widespread early administration in patients at risk.

    Drowning is a common cause of accidental death, particularly in younger people, and acute respiratory failure is common in these patients. This case report describes a healthy 18-year-old man who suffered a cardiorespiratory arrest due to submersion while swimming in a freshwater lake. First-responder cardiopulmonary resuscitation and defibrillation using an automated external defibrillator resulted in a return of spontaneous circulation. The patient was evacuated to a tertiary care center by a rotor-wing air medical crew. The crew experienced difficulties in oxygenating and ventilating the patient because of early-onset acute respiratory distress syndrome (ARDS). This case report describes the pathophysiology and prehospital management of a patient with suspected early-onset ARDS secondary to drowning. This case report is unique because it describes the oxygenation and ventilation difficulties encountered in managing this patient in the transport setting, and possible strategies to deal with these difficulties. Finally, this case report highlights the prehospital bypass decision-making process for patients requiring specialized medical care.

    Computerized gamma-scintigraphy provides a new method for the analysis of albumin flux in patients with pulmonary permeability edema. In this technique, 10 mCi of /sup 99/mTc -tagged human serum albumin is administered and lung:heart radioactivity ratios are determined. This ratio remains constant unless there is a leak of albumin, when a rising ratio with time, called the ''slope index'' (SI), is seen. Thirty-five scintigraphic studies were obtained in 28 patients by means of a portable computerized gamma-camera. Thirteen of these patients had clinical evidence of the acute respiratory distress syndrome (ARDS) and six had or were recovering from left ventricular induced congestive heart failure (CHF). Five of the patients with CHF and pulmonary capillary wedge pressure (PCWP) below 30 mm Hg had normal scintigraphic studies. The patients with ARDS were found to have significantly higher SIs than patients who did not have, or had recovered from, ARDS. Positive SIs were present from 1 to 8 days following the apparent onset of ARDS in seven studies in five patients. Recovery of gas exchange was associated with a return to a normal SI in four patients. In conclusion, computerized gamma-scintigraphy was a sensitive, noninvasive tool for the detection of a pathologic increase in pulmonary protein flux. Positive scintigraphic findings were associated with significantly impaired gas exchange. The method documented that the leak of albumin in patients with ARDS may last for days but resolves with recovery.

    Acute respiratory distress syndrome (ARDS) remains a significant hazard to human health and is clinically challenging because there are no prognostic biomarkers and no effective pharmacotherapy. The lung compartment metabolome may detail the status of the local environment that could be useful in ARDS biomarker discovery and the identification of drug target opportunities. However, neither the utility of bronchoalveolar lavage fluid (BALF) as a biofluid for metabolomics nor the optimal analytical platform for metabolite identification are established. To address this, we undertook a study to compare metabolites in BALF samples from patients with ARDS and healthy controls using a newly developed liquid chromatography (LC)-mass spectroscopy (MS) platform for untargeted metabolomics. Following initial testing of three different high performance liquid chromatography (HPLC) columns, we determined that reversed phase (RP)-LC and hydrophilic interaction chromatography (HILIC), were the most informative chromatographic methods because they yielded the most and highest quality data. Following confirmation of metabolite identification, statistical analysis resulted in 37 differentiating metabolites in the BALF of ARDS compared with health across both analytical platforms. Pathway analysis revealed networks associated with amino acid metabolism, glycolysis and gluconeogenesis, fatty acid biosynthesis, phospholipids and purine metabolism in the ARDS BALF. The complementary analytical platforms of RPLC and HILIC-LC generated informative, insightful metabolomics data of the ARDS lung environment. PMID:24289193

    The histopathological changes in the lungs of 12 related Dalmatians with idiopathic acute respiratory distress syndrome (ARDS) are described. Affected dogs had multiple foci of marked atypical hyperplasia and squamous metaplasia of the bronchiolar epithelium, patchy ongoing fibrosis with myofibroblastic metaplasia, smooth muscle hyperplasia and occasional honeycombing of alveolar walls, and hyperplasia of atypical type II pneumocytes. There was an abrupt transition between these proliferative lesions and areas of acute alveolar oedema with hyaline membranes in partially normal lung. Diseased areas were associated with moderate lymphohistiocytic interstitial inflammation. Immunohistochemical labelling for cytokeratin expression indicated that the metaplastic epithelium was of bronchiolar origin and that it extended into peribronchiolar alveolar spaces. Some of the bronchiolar lesions were pre-neoplastic and one adult dog suffered from bronchoalveolar carcinoma. These lesions are compared with the two forms of idiopathic interstitial pneumonia reported as causes of ARDS in man: acute interstitial pneumonia (AIP) and acute exacerbation of idiopathic pulmonary fibrosis (IPF). The observed lesions in the Dalmatians are distinct from the diffuse alveolar damage that characterizes AIP, but show some histological similarities to the usual interstitial pneumonia (UIP) that occurs in IPF with acute exacerbation in man. UIP has not previously been described in the dog.

    Necroptosis is a recently discovered necrotic cell death which is regulated by receptor interacting protein kinase 1 (RIPK1) and RIPK3 under the stimulus of death signal and can be inhibited by necrostatin-1 (Nec-1) specifically. Therefore, the aim was to investigate the role of necroptosis in a rat model of acute respiratory distress syndrome (ARDS) induced by oleic acid (OA) and assess the effect of Nec-1 on lung injury in ARDS. Our results found that RIPK1, RIPK3 and mixed lineage kinase domain-like protein (MLKL) were abundantly expressed in rat lung tissues of OA-induced ARDS. Nec-1 pretreatment improved pulmonary function and attenuated lung edema dramatically in OA-induced ARDS rats. Furthermore, Nec-1 reduced RIPK1-RIPK3 interaction and down-regulated RIPK1-RIPK3-MLKL signal pathway, and inhibited inflammatory response by reducing neutrophil infiltration and protein leakage into lung tissue in OA-induced ARDS. Collectively, our study proves the intervention of necroptosis in OA-induced ARDS. Moreover, our findings imply that Nec-1 plays an important role in the treatment of ARDS via inhibiting necroptosis and inflammation. PMID:27586277

    Acute Respiratory Distress Syndrome (ARDS) is understood as an inflammation-induced disruption of the alveolar endothelial-epithelial barrier that results in increased permeability and surfactant dysfunction followed by alveolar flooding and collapse. ARDS management relies on mechanical ventilation. The current challenge is to determine the optimal ventilatory strategies that minimize ventilator-induced lung injury (VILI) while providing a reasonable gas exchange. The data support that a tidal volume between 6-8 ml/kg of predicted body weight providing a plateau pressure < 30 cmH₂O should be used. High positive end expiratory pressure (PEEP) has not reduced mortality, nevertheless secondary endpoints are improved. The rationale used for high PEEP argues that it prevents cyclic opening and closing of airspaces, probably the major culprit of development of VILI. Chest computed tomography has contributed to our understanding of anatomic-functional distribution patterns in ARDS. Electric impedance tomography is a technique that is radiation-free, but still under development, that allows dynamic monitoring of ventilation distribution at bedside.

    Noninvasive ventilation has been proven to be effective strategies for reducing the need for endotracheal ventilation in preterm infant with respiratory distress syndrome (RDS), however the best option needs to be further determined. A single center, paired design, randomized, controlled trial was conducted between Jan 2011 and July 2014. Preterm twins with RDS were included. One of a pair was randomized to NIPPV, while another to NCPAP. Surfactant was administrated as rescue treatment. The primary outcome was the need for endotracheal ventilation. The secondary outcomes were the complications. 143 pairs were randomized and 129 pairs finished the trial. The rates of endotracheal ventilation did not differ significantly between NIPPV and NCPAP groups (11.9% vs 19.6%, P = 0.080). This difference was not observed in the subgroup of infants who received surfactant therapy (11.1% vs 19.7%, P = 0.087). No secondary outcomes also differed significantly between the two groups. NIPPV did not result in a significantly lower incidence of intubation as compared with NCPAP in preterm twins with RDS. PMID:26399752

    Acute respiratory distress syndrome (ARDS) is a medical emergency that threatens life. To this day, ARDS is very rarely reported by iodine contrast media, and there is no reported case of ARDS induced by gadolinium contrast media. Here, we present a case with ARDS after the use of gadobutrol (Gadovist) as a magnetic resonance imaging (MRI) contrast medium. A 26 years old female without any medical history, including allergic diseases and without current use of drugs, visited the emergency room for abdominal pain. Her abdominopelvic computed tomography with iodine contrast media showed a right ovarian cyst and possible infective colitis. Eighty-three hours later, she underwent pelvis MRI after injection of 7.5 mL (0.1 mL/kg body weight) of gadobutrol (Gadovist) to evaluate the ovarian cyst. She soon presented respiratory difficulty, edema of the lips, nausea, and vomiting, and we could hear wheezing upon auscultation. She was treated with dexamethasone, epinephrine, and norepinephrine. Her chest X-ray showed bilateral central bat-wing consolidative appearance. Managed with mechanical ventilation, she was extubated 3 days later and discharged without complications.

    The acute respiratory distress syndrome (ARDS), a severe form of acute lung injury (ALI), is a very common condition associated with critically ill patients, which causes substantial morbidity and mortality worldwide. Despite decades of research, effective therapeutic strategies for clinical ALI/ARDS are not available. In recent years, microRNAs (miRNAs), small non-coding molecules have emerged as a major area of biomedical research as they post-transcriptionally regulate gene expression in diverse biological and pathological processes, including ALI/ARDS. In this context, this present review summarizes a large body of evidence implicating miRNAs and their target molecules in ALI/ARDS originating largely from studies using animal and cell culture model systems of ALI/ARDS. We have also focused on the involvement of miRNAs in macrophage polarization, which play a critical role in regulating the pathogenesis of ALI/ARDS. Finally, the possible future directions that might lead to novel therapeutic strategies for the treatment of ALI/ARDS are also reviewed. J. Cell.

    Respiratory distress syndrome (RDS) is primarily due to decreased production of pulmonary surfactant, and it is associated with significant neonatal morbidity and mortality. Exogenous pulmonary surfactant therapy is currently the treatment of choice for RDS, as it demonstrates the best clinical and economic outcomes. Studies confirm the benefits of surfactant therapy to include reductions in mortality, pneumothorax, and pulmonary interstitial emphysema, as well as improvements in oxygenation and an increased rate of survival without bronchopulmonary dysplasia. Phospholipids (PL) and surfactant-associated proteins (SP) play key roles in the physiological activity of surfactant. Different types of natural and synthetic surfactant preparations are currently available. To date, natural surfactants demonstrate superior outcomes compared to the synthetic surfactants, at least during the acute phase of RDS. This disparity is often attributed to biochemical differences including the presence of surfactant-associated proteins in natural products that are not found in the currently available synthetic surfactants. Comparative trials of the natural surfactants strive to establish the precise differences in clinical outcomes among the different preparations. As new surfactants become available, it is important to evaluate them relative to the known benefits of the previously existing surfactants. In order to elucidate the role of surfactant therapy in the management of RDS, it is important to review surfactant biochemistry, pharmacology, and outcomes from randomized clinical trials.

    Purpose of review This review gives an update on current treatment options and novel concepts on the prevention and treatment of the acute respiratory distress syndrome (ARDS) in cardiovascular surgery patients. Recent findings The only proven beneficial therapeutic options in ARDS are those that help to prevent further ventilator-induced lung injury, such as prone position, use of lung-protective ventilation strategies, and extracorporeal membrane oxygenation. In the future also new approaches like mesenchymal cell therapy, activation of hypoxia-elicited transcription factors or targeting of purinergic signaling may be successful outside the experimental setting. Owing to the so far limited treatment options, it is of great importance to determine patients at risk for developing ARDS already perioperatively. In this context, serum biomarkers and lung injury prediction scores could be useful. Summary Preventing ARDS as a severe complication in the cardiovascular surgery setting may help to reduce morbidity and mortality. As cardiovascular surgery patients are of greater risk to develop ARDS, preventive interventions should be implemented early on. Especially, use of low tidal volumes, avoiding of fluid overload and restrictive blood transfusion regimes may help to prevent ARDS. PMID:26598954

    The use of low tidal volume ventilation and low to moderate positive end-expiratory pressure (PEEP) levels is a widespread strategy to ventilate patients with non-injured lungs during general anesthesia and in intensive care as well with mild to moderate acute respiratory distress syndrome (ARDS). Higher PEEP levels have been recommended in severe ARDS. Due to the presence of alveolar collapse, recruitment maneuvers (RMs) by causing a transient elevation in airway pressure (i.e. transpulmonary pressure) have been suggested to improve lung inflation in non-inflated and poorly-inflated lung regions. Various types of RMs such as sustained inflation at high pressure, intermittent sighs and stepwise increases of PEEP and/or airway plateau inspiratory pressure have been proposed. The use of RMs has been associated with mixed results in terms of physiological and clinical outcomes. The optimal method for RMs has not yet been identified. The use of RMs is not standardized and left to the individual physician based on his/her experience. Based on the same grounds, RMs have been proposed to improve lung aeration during general anesthesia. The aim of this review was to present the clinical evidence supporting the use of RMs in patients with ARDS and during general anesthesia and as well their potential biological effects in experimental models of acute lung injury.

    2011-09-01

    Acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) are characterized by excessive intraalveolar fibrin deposition, driven, at least in part by inflammation. The imbalance between activation of coagulation and inhibition of fibrinolysis in patients with ALI/ARDS favors fibrin formation and appears to occur both systemically and in the lung and airspace. Tissue factor (TF), a key mediator of the activation of coagulation in the lung, has been implicated in the pathogenesis of ALI/ARDS. As such, there have been numerous investigations modulating TF activity in a variety of experimental systems in order to develop new therapeutic strategies for ALI/ARDS. This review will summarize current understanding of the role of TF and other proteins of the coagulation cascade as well the fibrinolysis pathway in the development of ALI/ARDS with an emphasis on the pathways that are potential therapeutic targets. These include the TF inhibitor pathway, the protein C pathway, antithrombin, heparin, and modulation of fibrinolysis through plasminogen activator- 1 (PAI-1) or plasminogen activators (PA). Although experimental studies show promising results, clinical trials to date have proven unsuccessful in improving patient outcomes. Modulation of coagulation and fibrinolysis has complex effects on both hemostasis and inflammatory pathways and further studies are needed to develop new treatment strategies for patients with ALI/ARDS.

    Experimental approaches have been implemented to research the lung damage related-mechanism. These models show in animals pathophysiological events for acute respiratory distress syndrome (ARDS), such as neutrophil activation, reactive oxygen species burst, pulmonary vascular hypertension, exudative edema, and other events associated with organ dysfunction. Moreover, these approaches have not reproduced the clinical features of lung damage. Lung inflammation is a relevant event in the develop of ARDS as component of the host immune response to various stimuli, such as cytokines, antigens and endotoxins. In patients surviving at the local inflammatory states, transition from injury to resolution is an active mechanism regulated by the immuno-inflammatory signaling pathways. Indeed, inflammatory process is regulated by the dynamics of cell populations that migrate to the lung, such as neutrophils and on the other hand, the role of the modulation of transcription factors and reactive oxygen species (ROS) sources, such as nuclear factor kappaB and NADPH oxidase. These experimental animal models reproduce key components of the injury and resolution phases of human ALI/ARDS and provide a methodology to explore mechanisms and potential new therapies.

    Serum glucocorticoid levels were determined in 20 mothers and 43 premature infants who received prenatal betamethasone therapy for prevention of respiratory distress syndrome (RDS). Maternal betamethasone peaked at 75 microg cortisol equivalents per 100 ml 1 h after injection of 12 mg steroid and declined to half by 6 h. Betamethasone in cord blood was 14.3 microg cortisol equivalents per 100 ml at 1 h, decreased to a level of 4.7 at 20 h, and was not detected 2 days after a second dose at 24 h. After the second dose, the mean level of cortisol in cord blood was 5.9 microg per 100 ml compared with 13.05 microg per 100 ml (p less than 0.001) in untreated premature infants. The unbound glucocorticoid activity in treated infants delivered 1-10 h after the second dose (mean, 8.4 microg per 100 ml) is similar to the unbound cortisol level after birth in untreated premature infants who develop RDS. These findings indicate that (a) serum glucocorticoid levels in the physiologic stress range can induce lung maturation in the human and (b) antenatal treatment with this dose of betamethasone does not expose the human fetus to potentially harmful pharmacologic levels of steroid.

    The interaction between activated neutrophils and pulmonary endothelium is thought to contribute to the pathogenesis of the adult respiratory distress syndrome (ARDS), but its relation to ARDS severity, which may support a pathogenetic role, is unclear. Therefore, circulating inflammatory mediators, including the neutrophil chemoattractant and activator interleukin 8 (IL-8), the acute phase cytokine IL-6, and the neutrophil product elastase complexed to alpha 1-antitrypsin (alpha 1-AT), were measured prospectively, together with gas exchange, ventilatory and radiographic variables, in 13 mechanically ventilated patients with ARDS, mostly owing to sepsis, at admission into the intensive care unit. Measurements were repeated in the eight improving patients at the time that positive end-expiratory pressure could be reduced to 0 cm H2O. From the gas exchange, ventilatory and radiographic abnormalities, a lung injury score (LIS) was calculated. For pooled data, the LIS and the arterial PO2/inspiratory O2 fraction, the oxygenation ratio, correlated with plasma levels of IL-8 (rs = 0.60, P < 0.01 and rs = -0.65, P < 0.005, respectively), with levels of IL-6 (rs = 0.60, P < 0.01, and rs = -0.68, P < 0.005, respectively), and the oxygenation ratio related to elastase-alpha 1-AT (rs = -0.70, P < 0.005). Levels of IL-8 and IL-6 interrelated (rs = 0.61, P < 0.01) and related to the elastase complexes (rs = 0.45, P < 0.05). Hence, our data support a role of cytokine-induced activation of neutrophils in the clinical severity of ARDS.

    Since the first characterization of the adult respiratory distress syndrome (ARDS), knowledge of its aetiology and pathogenesis has grown considerably. In spite of this, mortality remains up to 50 to 90%, particularly if multiple organ failure is present. Because no causative clinical therapy is available up to now, significant attention is given to preventive measures like early operative stabilisation of long bone fractures, or prophylaxis of nosocomial infections. After clinical manifestation of ARDS, treatment focuses on functional disturbances of the cardiopulmonary system and on the underlying disease. The aim of this symptomatic therapy is to ensure oxygen supply according to the organisms demand. It is still unknown, however, whether the mortality of patients with ARDS can be reduced by optimising the oxygen supply. In general, oxygen supply can be enhanced by improving pulmonary gas exchange, cardiac output and blood oxygen transport capacity. For practical use the therapy often ends up with a therapeutical dilemma: On one hand, the improvement of the pulmonary gas exchange by application of PEEP can be associated with a critical decline in cardiac output, particularly if the afterload of the right ventricle is elevated. On the other hand, to increase cardiac output, both volume replacement and vasodilators can severely affect pulmonary gas exchange if the alveolo-capillary permeability is increased and pulmonary hypoxic vasoconstriction is disturbed. Thus, oxygen supply can be optimised only via invasive monitoring of the cardiorespiratory system. Although still experimental, the most promising approaches seem to be pharmacological interventions directed at suppressing the formation and effects of various humoral and cellular mediators. An improved understanding of the inflammatory processes might provide new insights in the pathophysiology of ARDS and the related therapeutic interventions. PMID:1863681

    To evaluate the effect of intrauterine cocaine exposure on lung maturity of very low birthweight infants, the medical records of all infants with birthweight < 1500 g born between January 1989 and December 1990 at DC General Hospital were reviewed. Infants with conditions known to cause lung maturity, severe congenital anomalies, proven early sepsis, and birthweight > or = 500 g were excluded. A total of 69 infants were included in the study. Chest roentgenograms of these infants were evaluated by a pediatric radiologist, who was unaware of the infant's medical course, for evidence of respiratory distress syndrome (RDS), and radiological findings were correlated with clinical signs. Forty infants were exposed to cocaine in utero (cocaine group) and 29 were not exposed (noncocaine group). African-American ethnicity, pregnancy-induced hypertension, prolonged rupture of membranes, and alcohol use were similar in both groups. Tobacco use among cocaine group mothers was higher (42.5% versus 13.8%; P = .01). Gestational age (28.3 +/- 2.8 versus 28.3 +/- 3 weeks), birthweight (966 +/- 282 versus 1059 +/- 295 g), male gender, and Apgar scores were similar in both groups. Thirty (75%) infants in the cocaine group developed RDS compared with 19 (66%) in the noncocaine group (P > .05). Using multiple logistic regression analysis and controlling for smoking, alcohol use, and prolonged rupture of membranes (24 to 72 hours), the incidence of RDS between the groups remained statistically insignificant. We conclude that intrauterine cocaine exposure does not alter the incidence of RDS in very low birthweight infants. PMID:8046765

    Background Plasmodium ovale is one of the causative agents of human malaria. Plasmodium ovale infection has long been thought to be non-fatal. Due to its lower morbidity, P. ovale receives little attention in malaria research. Methods Two Malaysians went to Nigeria for two weeks. After returning to Malaysia, they fell sick and were admitted to different hospitals. Plasmodium ovale parasites were identified from blood smears of these patients. The species identification was further confirmed with nested PCR. One of them was successfully treated with no incident of relapse within 12-month medical follow-up. The other patient came down with malaria-induced respiratory complication during the course of treatment. Although parasites were cleared off the circulation, the patient’s condition worsened. He succumbed to multiple complications including acute respiratory distress syndrome and acute renal failure. Results Sequencing of the malaria parasite DNA from both cases, followed by multiple sequence alignment and phylogenetic tree construction suggested that the causative agent for both malaria cases was P. ovale curtisi. Discussion In this report, the differences between both cases were discussed, and the potential capability of P. ovale in causing severe complications and death as seen in this case report was highlighted. Conclusion Plasmodium ovale is potentially capable of causing severe complications, if not death. Complete travel and clinical history of malaria patient are vital for successful diagnoses and treatment. Monitoring of respiratory and renal function of malaria patients, regardless of the species of malaria parasites involved is crucial during the course of hospital admission. PMID:24180319

    To identify the best lung ventilation strategy for acute respiratory distress syndrome (ARDS), we performed a network meta-analysis. The Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, CINAHL, and the Web of Science were searched, and 36 eligible articles were included. Compared with higher tidal volumes with FiO2-guided lower positive end-expiratory pressure [PEEP], the hazard ratios (HRs) for mortality were 0.624 (95% confidence interval (CI) 0.419–0.98) for lower tidal volumes with FiO2-guided lower PEEP and prone positioning and 0.572 (0.34–0.968) for pressure-controlled ventilation with FiO2-guided lower PEEP. Lower tidal volumes with FiO2-guided higher PEEP and prone positioning had the greatest potential to reduce mortality, and the possibility of receiving the first ranking was 61.6%. Permissive hypercapnia, recruitment maneuver, and low airway pressures were most likely to be the worst in terms of all-cause mortality. Compared with higher tidal volumes with FiO2-guided lower PEEP, pressure-controlled ventilation with FiO2-guided lower PEEP and lower tidal volumes with FiO2-guided lower PEEP and prone positioning ventilation are associated with lower mortality in ARDS patients. Lower tidal volumes with FiO2-guided higher PEEP and prone positioning ventilation and lower tidal volumes with pressure-volume (P–V) static curve-guided individual PEEP are potential optimal strategies for ARDS patients.

    Mechanical ventilation may promote overdistension-induced pulmonary lesions in patients with acute respiratory distress syndrome (ARDS). The static pressure-volume (P-V) curve of the respiratory system can be used to determine the lung volume and corresponding static airway pressure at which lung compliance begins to diminish (the upper inflection point, or UIP). This fall in compliance may indicate overdistension of lung units. We prospectively studied 42 patients receiving mechanical ventilation with an FIO2 of 0.5 or more for at least 24 h. According to the Lung Injury Score (LIS), 25 patients were classified as having ARDS (LIS > 2.5), while 17 patients constituted a non-ARDS control group. The P-V curve was obtained every 2 d. Mechanical ventilation initially used standard settings (volume-control mode, a positive end-expiratory pressure [PEEP] adjusted to the lower inflection point on the P-V curve, and a tidal volume [VT] of 10 ml/kg). The end-inspiratory plateau pressure (Pplat) was compared to the UIP, and VT was lowered when the Pplat was above the UIP. In the range of lung volume studied on the P-V curves (up to 1600 ml), a UIP could be shown in only one control patient (at 23 cm H2O). By contrast, a UIP was present on the P-V curve obtained from all patients with ARDS, corresponding to a mean airway pressure of 26 +/- 6 cm H2O, a lung volume of 850 +/- 200 ml above functional residual capacity and 610 +/- 235 ml above PEEP.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7599810

    Acute Respiratory Distress Syndrome (ARDS) is characterized by lung injury and damage to the alveolar type II cells. This study sought to determine if endogenous surfactant is altered in ARDS. Bronchoalveolar lavage was performed in patients at-risk to develop ARDS (AR, n = 20), with ARDS (A, n = 66) and in normal subjects (N, n = 29). The crude surfactant pellet was analyzed for total phospholipids (PL), individual phospholipids, SP-A, SP-B, and minimum surface tension (STmin). PL was decreased in both AR and A (3.48 +/- 0.61 and 2.47 +/- 0.40 mumol/ml, respectively) compared to N (7.99 +/- 0.60 mumol/ml). Phosphatidylcholine was decreased in A (62.64 +/- 2.20% PL) compared to N (76.27 +/- 2.05% PL). Phosphatidylglycerol was 11.58 +/- 1.21% PL in N and was decreased to 6.48 +/- 1.43% PL in A. SP-A was 123.64 +/- 20.66 micrograms/ml in N and was decreased to 49.28 +/- 21.68 micrograms/ml in AR and to 29.88 +/- 8.49 micrograms/ml in A. SP-B was 1.28 +/- 0.33 micrograms/ml in N and was decreased to 0.57 +/- 0.24 micrograms/ml in A. STmin was increased in AR (15.1 +/- 2.53 dyn/cm) and A (29.04 +/- 2.05 dyn/cm) compared to N (7.44 +/- 1.61 dyn/cm). These data demonstrate that the chemical composition and functional activity of surfactant is altered in ARDS. Several of these alterations also occur in AR, suggesting that these abnormalities occur early in the disease process. PMID:1752956

    Bedside use of Doppler echocardiography is being featured as a promising, clinically useful tool in assessing the pulmonary circulation in patients with acute respiratory distress syndrome (ARDS). The present review is aimed at summarizing the available evidence obtained with echocardiography on right ventricle (RV) function and pulmonary circulation in ARDS and to highlight the potential of this technique in clinical practice (only articles in English language were considered). According to the available evidence on echocardiographic findings, the following conclusions can be drawn: (a) echocardiography (transthoracic and transesophageal) has a growing role in the management ARDS patients mainly because of the strict interactions between the lung (and ventilation) and the RV and pulmonary circulation; (b) there may be a continuum of alterations in RV size and function and pulmonary circulation which may end in the development of acute cor pulmonale, probably paralleling ARDS disease severity; and (c) the detection of acute cor pulmonale should prompt intensivists to tailor their ventilatory strategy to the individual patient depending on the echocardiography findings. Bearing in mind the clinical role and growing importance of echocardiography in ARDS and the available evidence on this topic, we present a flow chart including the parameters to be measured and the timing of echo exams in ARDS patients. Despite the important progress that echocardiography has gained in the evaluation of patients with ARDS, several open questions remain and echocardiography still appears to be underused in these patients. A more systematic use of echocardiography (mainly through shared protocols) in ARDS could help intensivists to tailor the optimal treatment in individual patients as well as highlighting the limits and potential of this methodology in patients with ALI.

    We prospectively evaluated the patterns of pulmonary structural and functional changes in 100 consecutive surgical intensive care unit trauma patients who had (1) emergent major surgery, (2) a pelvic fracture, or (3) two or more major long bone fractures. For each patient, arterial blood gas measurements (ABGs), central venous pressure (CVP), pulmonary capillary occlusion pressure (PAOP), thoracic compliance, arterial oxygen tension/fraction of inspired oxygen (PAO2/FIO2), pulmonary venous admixture (Qs/Qt), and portable chest roentgenograms were sequentially tracked. The senior staff radiologist interpreted all chest roentgenograms. Pulmonary infiltration was quantitated in each of six fields using a scale ranging from 0 to 4, with 0 being no infiltration and 4 being the maximum. Adult respiratory distress syndrome (ARDS) was defined as follows: Qs/Qt > or = 20%, PAO2/FIO2 < 250 or both; dependence on mechanical ventilation for life support for > or = 24 hours; PAOP or CVP or both < 20 mm Hg; and thoracic compliance < 50 mL/cm H2O. Time zero (T0) the time of onset of ARDS, was defined as the time these criteria were met. Eighty-three of 100 study group patients had penetrating injuries, and 17 were admitted with blunt trauma. Fifty-one of 100 patients developed ARDS: 36 of 51 died. Only 4 of 49 (8%) patients without ARDS died. The injured lungs of patients with and without ARDS had similar amounts of infiltration over most measured time intervals. The noninjured lungs of the ARDS patients, however, had significantly greater infiltration than those without ARDS at T0 and over subsequent time intervals.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background Aspiration of oral or gastric contents into the larynx and lower respiratory tract is a common problem in acute stroke patients, which significantly increases the incidence of acute respiratory distress syndrome (ARDS). However, little is known about the clinical characteristics of aspiration-related ARDS in acute stroke patients. Methods Over 17-month period a retrospective cohort study was done on 1495 consecutive patients with acute stroke. The data including demographic characteristics, clinical manifestations, laboratory examinations, chest imaging, and hospital discharge status were collected to analysis. Results Aspiration-related ARDS was diagnosed in 54 patients (3.6%). The most common presenting symptom was tachypnea (respiratory rate ≥25 breaths/min) in 50 cases. Computed tomography (CT) images usually demonstrated diffuse ground-glass opacities (GGOs) and inhomogeneous patchy consolidations involving the low lobes. Age, NIHSS score, GCS score, dysphagia, dysarthria, hemoglobin concentration, serum aspertate aminotransferase (AST), serum albumin, serum sodium, and admission glucose level were independently associated with aspiration-related ARDS (odds ratio (OR) 1.05, 95% confidence interval (CI) (1.04–1.07); OR 2.87, (2.68–3.63); OR 4.21, (3.57–5.09); OR 2.18, (1.23–3.86); OR 1.67, (1.31–2.14); OR 2.31, (1.11–4.84); OR 1.68, (1.01–2.80); OR 2.15, (1.19–3.90); OR 1.92, (1.10–3.36) and OR 1.14, (1.06–1.21) respectively). Conclusions Aspiration-related ARDS frequently occurs in acute stroke patient with impairment consciousness. It is advisable that performing chest CT timely may identify disease early and prompt treatment to rescue patients. PMID:25790377

    Respiratory distress syndrome (RDS) and bronchopulmonary dysplasia remain the leading causes of preterm infant morbidity, mortality, and lifelong disability. Research to improve outcomes requires translational large animal models for RDS. Preterm pigs delivered by caesarian section at gestation days (GD) 98, 100, 102, and 104 were provided 24 h of neonatal intensive care, monitoring (pulse oximetry, blood gases, serum biomarkers, radiography), and nutritional support, with or without intubation and mechanical ventilation (MV; pressure control ventilation with volume guarantee). Spontaneous development of RDS and mortality without MV are inversely related with GD at delivery and correspond with inadequacy of tidal volume and gas exchange. GD 98 and 100 pigs have consolidated lungs, immature alveolar architecture, and minimal surfactant protein-B expression, and MV is essential at GD 98. Although GD 102 pigs had some alveoli lined by pneumocytes and surfactant was released in response to MV, blood gases and radiography revealed limited recruitment 1-2 h after delivery, and mortality at 24 h was 66% (35/53) with supplemental oxygen provided by a mask and 69% (9/13) with bubble continuous positive airway pressure (8-9 cmH2O). The lungs at GD 104 had higher densities of thin-walled alveoli that secreted surfactant, and MV was not essential. Between GD 98 and 102, preterm pigs have ventilation inadequacies and risks of RDS that mimic those of preterm infants born during the saccular phase of lung development, are compatible with standards of neonatal intensive care, and are alternative to fetal nonhuman primates and lambs.

    Background Infant respiratory distress syndrome (IRDS) is the most common respiratory disease in preterm infants, and is associated with considerable morbidity and mortality. Valid data on IRDS are important in clinical epidemiological research. Objectives The objective of this study was to estimate the positive predictive value (PPV) of the IRDS diagnosis registered in the population-based Danish National Patient Registry according to the International Classification of Diseases, 8th and 10th revisions. Methods Between January 1, 1977 and December 31, 2008, we randomly selected three patients per year, 96 in total, who were registered with an IRDS diagnosis in the Danish National Patient Registry and living in the northern part of Denmark. Data on the infants included information on the presence of predefined clinical symptoms. We defined IRDS as the presence of at least two of four clinical symptoms (tachypnea, retractions or nasal flaring, grunting, and central cyanosis), which had to be present for more than 30 minutes. Using medical record review as the reference standard, we computed the positive predictive value of the registered IRDS diagnosis including 95% confidence intervals (CIs). Results We located the medical record for 90 of the 96 patients (94%), and found an overall PPV of the IRDS diagnosis of 81% (95% CI 72%–88%). This did not vary substantially between primary and secondary diagnoses. The PPV was higher, at 89% (95% CI 80%–95%), for preterm infants born before 37 weeks of gestation. Conclusion The PPV of the IRDS diagnosis in the Danish National Patient Registry is reasonable when compared with symptoms described in the corresponding medical records. The Danish National Patient Registry is a useful data source for studies of IRDS, particularly if restricted to preterm infants. Nonetheless, the potential impact of misclassification of the IRDS diagnosis must be considered. PMID:23976865

    Considerable uncertainty remains about the best ventilator strategies for the mitigation of atelectasis and associated airspace stretch in patients with acute respiratory distress syndrome (ARDS). In addition to several immediate physiological effects, atelectasis increases the risk of ventilator-associated lung injury (VALI), which has been shown to significantly worsen ARDS outcomes. A number of lung imaging techniques have made substantial headway in clarifying the mechanisms of atelectasis. This paper reviews the contributions of CT, PET, and conventional MRI to understanding this phenomenon. In doing so, it also reveals several important shortcomings inherent to each of these approaches. Once these shortcomings have been made apparent, we describe how hyperpolarized gas magnetic resonance imaging (HP MRI)—a technique that is uniquely able to assess responses to mechanical ventilation and lung injury in peripheral airspaces—is poised to fill several of these knowledge gaps. The HP-MRI-derived apparent diffusion coefficient (ADC) quantifies the restriction of 3He diffusion by peripheral airspaces, thereby obtaining pulmonary structural information at an extremely small scale. Lastly, this paper reports the results of a series of experiments that measured ADC in mechanically ventilated rats in order to investigate (i) the effect of atelectasis on ventilated airspaces; (ii) the relationship between positive end-expiratory pressure (PEEP), hysteresis, and the dimensions of peripheral airspaces; and (iii) the ability of PEEP and surfactant to reduce airspace dimensions after lung injury. An increase in ADC was found to be a marker of atelectasis-induced overdistension. With recruitment, higher airway pressures were shown to reduce stretch rather than worsen it. Moving forward, HP MRI has significant potential to shed further light on the atelectatic processes that occur during mechanical ventilation. PMID:24920074

    Animal studies using oleic acid (OA) model to produce acute respiratory distress syndrome (ARDS) have been inconsistent. Therefore, the present study was undertaken to establish an acute model of ARDS in rats using OA and to characterize its effect on cardio-respiratory parameters and lethality. The trachea, jugular vein and femoral artery of anesthetized adult rats were cannulated. A dose of OA (30-90 microL; iv) was injected in each animal and changes in respiratory frequency (RF), heart rate (HR) and mean arterial pressure (MAP) were recorded. Minute ventilation and PaO2/FiO2 (P/F) ratio were also determined. At the end, lungs were excised for determination of pulmonary water content and histological examination. At all doses of OA, there was immediate decrease followed by increase in RF, however at 75 and 90 microL of OA, RF decreased abruptly and the animals died by 63 +/- 8.2 min and 19 +/- 6.3 min; respectively. In all the groups, HR and MAP changes followed the respiratory changes. The minute ventilation increased in a dose-dependent manner while the values of P/F ratio decreased correspondingly. Pulmonary edema was induced at all doses. Histological examination of the lung showed alveolar damage, microvascular congestion, microvascular injury, infiltration of inflammatory cells, pulmonary edema and necrosis in a dose-dependent manner. With these results, OA can be used to induce different grades of ARDS in rats and OA doses of 50, 60 and 75 microL resemble mild, moderate and severe forms of ARDS respectively. Hence, OA model serves as a useful tool to study the pathophysiology of ARDS.

    Acute respiratory distress syndrome (ARDS) is a devastating disorder characterized by increased alveolar permeability with no effective treatment beyond supportive care. Current mechanisms underlying ARDS focus on alveolar endothelial and epithelial injury caused by products of innate immune cells and platelets. However, the role of adaptive immune cells in ARDS remains largely unknown. Here we report that expansion of antigen-specific αβT helper 17 (αβTH17) cells contribute to ARDS by local secretion of IL-17A, which in turn directly increases alveolar epithelial permeability. Mice with a highly restrictive defect in antigen-specific αβTH17 cells were protected from experimental ARDS induced by a single dose of endotracheal lipopolysaccharide (LPS). Loss of IL-17 receptor C or antibody blockade of IL-17A was similarly protective, further suggesting that IL-17A released by these cells was responsible for this effect. LPS induced a rapid and specific clonal expansion of αβTH17 cells in the lung, as determined by deep sequencing of the hypervariable CD3RβVJ region of the T cell receptor. Our findings could be relevant to ARDS in humans, since we found significant elevation of IL-17A in bronchoalveolar lavage (BAL) fluid from patients with ARDS and recombinant IL-17A directly increased permeability across cultured human alveolar epithelial monolayers. These results reveal a previously unexpected role for adaptive immune responses that increase alveolar permeability in ARDS and suggest that αβTH17 cells and IL-17A could be novel therapeutic targets for this currently untreatable disease.

    To characterize the tachykininergic effects in fire smoke (FS)-induced acute respiratory distress syndrome (ARDS), we designed a series of studies in rats. Initially, 20 min of FS inhalation induced a significant increase of substance P (SP) in bronchoalveolar lavage fluid (BALF) at 1 h and persisted for 24 h after insult. Conversely, FS disrupted 51.4, 55.6, 46.3, and 43.0% enzymatic activity of neutral endopeptidase (NEP, a primary hydrolyzing enzyme for SP) 1, 6, 12, and 24 h after insult, respectively. Immunolabeling density of NEP in the airway epithelium largely disappeared 1 h after insult due to acute cell damage and shedding. These changes were also accompanied by extensive influx of albumin and granulocytes/lymphocytes in BALF. Furthermore, levels of BALF SP and tissue NEP activity dose dependently increased and decreased, respectively, following 0, low (10 min), and high (20 min) levels of FS inhalation. However, neither the time-course nor the dose-response study observed a significant change in the highest affinity neurokinin-1 receptor (NK-1R) for SP. Finally, treatment (10 mg/kg im) with SR-140333B, an NK-1R antagonist, significantly prevented 20-min FS-induced hypoxemia and pulmonary edema 24 h after insult. Further examination indicated that SR-140333B (1.0 or 10.0 mg/kg im) fully abolished early (1 h) plasma extravasation following FS. Collectively, these findings suggest that a combination of sustained SP and NEP inactivity induces an exaggerated neurogenic inflammation mediated by NK-1R, which may lead to an uncontrolled influx of protein-rich edema fluid and cells into the alveoli as a consequence of increased vascular permeability.

    Background Bodily distress syndrome (BDS) is a newly proposed diagnosis of medically unexplained symptoms, which is based on empirical research in primary care. Aim To estimate the frequency of BDS in primary care and describe the characteristics of patients with BDS. Design and setting A cross-sectional study of primary care patients in urban and rural areas of Central Denmark Region. Method Data were obtained from GP one-page registration forms, patient questionnaires (including a checklist for BDS), and national registers. Results A total of 1356 primary care patients were included, of whom 230 patients (17.0%, 95% confidence intervals [CI] = 15.0 to 19.1) fulfilled the BDS criteria. BDS was more common among primary care patients aged 41–65 years (odds ratio [OR] = 1.9, 95% CI = 1.3 to 3.0) and was equally frequent among males and females (female sex, OR 0.9, 95% CI = 0.6 to 1.3). Patients with BDS were characterised by poor health-related quality of life (HRQOL) on the 12-item Short-Form Health Survey, that is, physical component summary scores <40 (OR 20.5, 95% CI = 12.9 to 32.4) and mental component summary scores <40 (OR 3.5, 95% CI = 2.2 to 5.6). Furthermore, patients with BDS were more likely to have high scores on the Symptom Checklist for anxiety (OR 2.2, 95% CI = 1.4 to 3.4) and depression (OR 5.1, 95% CI = 3.3 to 7.9), but regression analyses showed that mental morbidity did not account for the poor HRQOL. Conclusion BDS is common among primary care patients, and patients with BDS have a higher probability of poor HRQOL and mental health problems. PMID:26324499

    Cardiac catheterization studies have demonstrated that Doppler-derived flow velocities in the ductal flow jet and the left pulmonary artery accurately predict the aortopulmonary pressure difference and left-to-right shunt size in newborns. To assess the presence of persistent pulmonary hypertension in premature newborns with various degrees of respiratory distress syndrome (RDS) severity, we estimated pulmonary artery pressure from the aortopulmonary pressure difference and pulmonary blood flow from the left pulmonary artery flow velocity with color-flow-directed, pulsed Doppler echocardiography. Seventy-nine premature neonates were divided into three groups--no or mild RDS (n = 27), severe RDS (n = 38), and fatal RDS (n = 14)--and compared with a group of healthy term neonates (n = 34). In premature and term neonates with no/mild RDS the mean +/- SEM aortopulmonary pressure difference increased from 7.3 +/- 0.4 and 6.6 +/- 0.5 mm Hg to 22.8 +/- 1.4 and 21.4 +/- 1.1 mm Hg over the first 24 hours (P < .001). The mean aortopulmonary pressure difference was 0.9 +/- 0.3 mm Hg during the first 72 hours in neonates with fatal RDS, but increased from 1.5 +/- 0.3 mm Hg at 4 hours to 7.4 +/- 0.6 at 24 hours and 21.5 +/- 0.7 mm Hg at 72 hours of age in neonates with severe RDS. Left pulmonary artery velocity time integrals were 18.3 +/- 0.5 cm in premature and 18.8 +/- 0.5 cm in term neonates with no/mild RDS at 12 hours vs 11.2 +/- 0.4 cm in neonates with severe and 9.9 +/- 0.5 cm in neonates with fatal RDS (P < .001).(ABSTRACT TRUNCATED AT 250 WORDS)

    Objective: To assess the safety and efficacy of combining extracorporeal Co2 removal with continuous renal replacement therapy in patients presenting with acute respiratory distress syndrome and acute kidney injury. Design: Prospective human observational study. Settings: Patients received volume-controlled mechanical ventilation according to the acute respiratory distress syndrome net protocol. Continuous venovenous hemofiltration therapy was titrated to maintain maximum blood flow and an effluent flow of 45 mL/kg/h with 33% predilution. Patients: Eleven patients presenting with both acute respiratory distress syndrome and acute kidney injury required renal replacement therapy. Interventions: A membrane oxygenator (0.65 m2) was inserted within the hemofiltration circuit, either upstream (n = 7) or downstream (n = 5) of the hemofilter. Baseline corresponded to tidal volume 6 mL/kg of predicted body weight without extracorporeal Co2 removal. The primary endpoint was 20% reduction in Paco2 at 20 minutes after extracorporeal Co2 removal initiation. Tidal volume was subsequently reduced to 4 mL/kg for the remaining 72 hours. Measurements and Main Results: Twelve combined therapies were conducted in the 11 patients. Age was 70 ± 9 years, Simplified Acute Physiology Score II was 69 ± 13, Sequential Organ Failure Assessment score was 14 ± 4, lung injury score was 3 ± 0.5, and Pao2/Fio2 was 135 ± 41. Adding extracorporeal Co2 removal at tidal volume 6 mL/kg decreased Paco2 by 21% (95% CI, 17–25%), from 47 ± 11 to 37 ± 8 Torr (p < 0.001). Lowering tidal volume to 4 mL/kg reduced minute ventilation from 7.8 ± 1.5 to 5.2 ± 1.1 L/min and plateau pressure from 25 ± 4 to 21 ± 3 cm H2O and raised Paco2 from 37 ± 8 to 48 ± 10 Torr (all p < 0.001). On an average of both positions, the oxygenator’s blood flow was 410 ± 30 mL/min and the Co2 removal rate was 83 ± 20 mL/min. The oxygenator blood flow (p <0.001) and the Co2 removal rate (p = 0.083) were higher when

    Objective To compare the efficacy and safety of a new porcine-derived pulmonary surfactant developed by Instituto Butantan with those of animal-derived surfactants commercially available in Brazil, regarding neonatal mortality and the major complications of prematurity in preterm newborns with birth weight up to 1500g and diagnosed with respiratory distress syndrome. Methods Neonates diagnosed with respiratory distress syndrome were randomized to receive either Butantan surfactant (Butantan group) or one of the following surfactants: Survanta® or Curosurf®. Newborns receiving Survanta® or Curosurf® comprised the control group. The main outcome measures were mortality rates at 72 hours and at 28 days of life; the typical complications of prematurity as evaluated on the 28th day of life were defined as secundary outcomes. Results No differences were observed between the Butantan (n=154) and control (n=173) groups in relation to birth weight, gestational age, sex, and prenatal use of corticosteroids, or in mortality rates both at 72 hours (14.19% versus 14.12%; p=0.98) and at 28 days (39.86% versus 33.33%; p=0.24) of life. Higher 1- and 5-minute Apgar scores were observed among control group newborns. No differences were observed as regards the secondary outcomes, except for greater need for supplemental oxygen and a higher incidence of interstitial pulmonary emphysema in the Butantan group. Conclusion The mortality rates at 72 hours and 28 days of life and the incidence of major complications of prematurity were comparable to those found with the animal-derived surfactants commercially available in Brazil, showing the efficacy and safety of the new surfactant in the treatment of respiratory distress syndrome in newborns.

    Objective to identify relationships between moral distress and Burnout in the professional performance from the perceptions of the experiences of nursing workers. Methods this is a survey type study with 375 nursing workers working in three different hospitals of southern Rio Grande do Sul, with the application of adaptations of the Moral Distress Scale and the Maslach Burnout Inventory, validated and standardized for use in Brazil. Data validation occurred through factor analysis and Cronbach's alpha. For the data analysis bivariate analysis using Pearson's correlation and multivariate analysis using multiple regression were performed. Results the existence of a weak correlation between moral distress and Burnout was verified. A possible positive correlation between Burnout and therapeutic obstinacy, and a negative correlation between professional fulfillment and moral distress were identified. Conclusion the need was identified for further studies that include mediating and moderating variables that may explain more clearly the models studied. PMID:24553701

    A 67-year-old woman was diagnosed as having scrub typhus with pneumonitis. On admission, she was started on a combination therapy with levofloxacin and doxycycline. However, the patient developed severe acute respiratory distress syndrome (ARDS) on the 2nd day, and as a result, she underwent extracorporeal membrane oxygenation (ECMO). She was weaned from ECMO on the 10th day, as her respiratory status gradually improved. She was discharged without sequelae on the 23rd day. The outcome suggests that the use of ECMO should be considered for patients with ARDS induced from scrub typhus. PMID:27458040

    The relationship between clinico-biochemical characteristics and self reported psychological parameters in 42 women with polycystic ovary syndrome (PCOS) and 42 age-matched healthy controls was examined. The General Health Questionnaire was used (GHQ-12) to ascertain emotional distress and the Beck Depression Inventory (BDI) to determine depressive symptoms. Emotional distress, depressive symptoms, hirsutism score, body mass index (BMI), waist-to-hip ratio (WHR), luteinizing hormone/follicle-stimulating hormone ratio, serum total testosterone, dehydroepiandrosterone sulphate levels and the insulin resistance index were significantly greater in women with PCOS than in healthy women. The BDI and GHQ-12 scores of the women with PCOS were significantly higher than those of the control group (BDI, 11.69 +/- 9.49 vs 5.80 +/- 4.58; GHQ-12, 3.38 +/- 3.38 vs 1.54 +/- 1.97, respectively), and BMI and WHR were positively correlated with the BDI and GHQ-12 scores. Clinicians should be aware of the increased risk of emotional distress and depression in women with PCOS, especially those who are obese, and of the need to screen these patients for such symptoms.

    Despite high in-hospital mortality associated with acute respiratory distress syndrome (ARDS), there is no effective therapeutic strategy. We tested the hypothesis that combined melatonin-mitochondria treatment ameliorates 100% oxygen-induced ARDS in rats. Adult male Sprague-Dawley rats (n = 40) were equally categorized into normal controls, ARDS, ARDS-melatonin, ARDS with intravenous liver-derived mitochondria (1500 μg per rat 6 hr after ARDS induction), and ARDS receiving combined melatonin-mitochondria. The results showed that 22 hr after ARDS induction, oxygen saturation (saO2 ) was lowest in the ARDS group and highest in normal controls, significantly lower in ARDS-melatonin and ARDS-mitochondria than in combined melatonin-mitochondria group, and significantly lower in ARDS-mitochondria than in ARDS-melatonin group. Conversely, right ventricular systolic blood pressure and lung weight showed an opposite pattern compared with saO2 among all groups (all P < 0.001). Histological integrity of alveolar sacs showed a pattern identical to saO2 , whereas lung crowding score exhibited an opposite pattern (all P < 0.001). Albumin level and inflammatory cells (MPO+, CD40+, CD11b/c+) from bronchoalveolar lavage fluid showed a pattern opposite to saO2 (all P < 0.001). Protein expression of indices of inflammation (MMP-9, TNF-α, NF-κB), oxidative stress (oxidized protein, NO-1, NOX-2, NOX-4), apoptosis (mitochondrial Bax, cleaved caspase-3, and PARP), fibrosis (Smad3, TGF-β), mitochondrial damage (cytochrome C), and DNA damage (γ-H2AX+) exhibited an opposite pattern compared to saO2 in all groups, whereas protein (HO-1, NQO-1, GR, GPx) and cellular (HO-1+) expressions of antioxidants exhibited a progressively increased pattern from normal controls to ARDS combined melatonin-mitochondria group (all P < 0.001). In conclusion, combined melatonin-mitochondrial was superior to either treatment alone in attenuating ARDS in this rat model.

  3. Role of Inhaled Nitric Oxide in the Management of Severe Acute Respiratory Distress Syndrome

    Hunt, Juliette Lucinda; Bronicki, Ronald A.; Anas, Nick

    2016-01-01

    To date, there have been several systematic reviews with meta-analysis that have shown no reduction in mortality with the use of inhaled nitric oxide (iNO) in patients with acute respiratory distress syndrome (ARDS). Importantly, these reports fail to make a distinction between the pediatric and adult patient. The number of adult patients in these reviews are far greater than the number of pediatric patients, which makes it difficult to interpret the data regarding the role of iNO on the pediatric population. Extrapolating data from the adult population to the pediatric population is complicated as we know that physiology and the body’s response to disease can be different between adult and pediatric patients. iNO has been demonstrated to improve outcomes in term and near-term infants with hypoxic respiratory failure associated with pulmonary hypertension. Recently, Bronicki et al. published a prospective randomized control trial investigating the impact of iNO on the pediatric patient population with acute respiratory failure. In this study, a benefit of decreased duration of mechanical ventilation and an increased rate of ECMO-free survival was demonstrated in patients who were randomized to receiving iNO, suggesting that there may be benefit to the use of iNO in pediatric ARDS (PARDS) that has not been demonstrated in adults. iNO has repeatedly been shown to transiently improve oxygenation in all age groups, and yet neonates and pediatric patients have shown improvement in other outcomes that have not been seen in adults. The mechanism that explains improvement with the use of iNO in these patient populations are not well understood but does not appear to be solely a result of sustained improvement in oxygenation. There are physiologic studies that suggest alternative mechanisms for explaining the positive effects of iNO, such as platelet aggregation inhibition and reduction in systemic inflammation. Hence, the role of iNO by various mechanisms and in various

    Background It is unclear whether an “obesity paradox” exists in the respiratory system, especially in acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). Previous studies have postulated a causal relation between obesity and ARDS/ALI but have lacked power to form a definitive conclusion. Objective To investigate the relationships between obesity, ARDS/ALIrisk, and mortality. Methods A systematic search current to April 2016 was performed in Pubmed, EMBASE, Medline, Cochrane databases to find relevant studies. All studies that estimate the effect of obesity in the morbidity and mortality of ARDS/ALI were included. Results A total of 24 studies including 9,187,248 subjects were analyzed. The combined results from 16 studies that examined the effect of obesity in morbidity of ARDS/ALI showed an89% increase in odds ratio(pooled odds ratios (OR) 1.89, 95% confidence intervals (CI) 1.45 to 2.47). In subgroup analysis, compared to normal weight, obesity was associated with an increased risk of ARDS/ALI (OR1.57, 95% CI 1.30–1.90 for obese (BMI30-39.9kg/m2); OR1.75, 95% CI 1.42–2.15 for obese(BMI≥30kg/m2); OR1.67, 95% CI 1.04–2.68 for morbid obese(BMI≥40kg/m2)). The combined results from 9 studies that examined the effect of obesity in mortality of ARDS/ALI had a pooled odds ratio(pooled OR 0.63, 95% CI 0.41 to 0.98). Inversely, obesity was significantly associated with reduced risk of ARDS/ALI mortality(OR0.88, 95% CI 0.78–1.00 for overweight(BMI≤18.5m2); OR0.74, 95% CI 0.64–0.84 for obese (BMI30-39.9kg/m2);OR0.84, 95% CI 0.75–0.94 for 60days mortality; OR0.38, 95% CI 0.22–0.66 for 90days mortality). Conclusions Our data identify obesity as an important risk factor for the development of ARDS/ALI; however, ARDS/ALI outcomes are improved in this population when compared to individuals with a normal body mass index. This meta-analysis results supported ‘‘obesity paradox” in ARDS/ALI. PMID:27684705

  5. Low-dose CT for quantitative analysis in acute respiratory distress syndrome

    PubMed Central

    2013-01-01

    Introduction The clinical use of serial quantitative computed tomography (CT) to characterize lung disease and guide the optimization of mechanical ventilation in patients with acute respiratory distress syndrome (ARDS) is limited by the risk of cumulative radiation exposure and by the difficulties and risks related to transferring patients to the CT room. We evaluated the effects of tube current-time product (mAs) variations on quantitative results in healthy lungs and in experimental ARDS in order to support the use of low-dose CT for quantitative analysis. Methods In 14 sheep chest CT was performed at baseline and after the induction of ARDS via intravenous oleic acid injection. For each CT session, two consecutive scans were obtained applying two different mAs: 60 mAs was paired with 140, 15 or 7.5 mAs. All other CT parameters were kept unaltered (tube voltage 120 kVp, collimation 32 × 0.5 mm, pitch 0.85, matrix 512 × 512, pixel size 0.625 × 0.625 mm). Quantitative results obtained at different mAs were compared via Bland-Altman analysis. Results Good agreement was observed between 60 mAs and 140 mAs and between 60 mAs and 15 mAs (all biases less than 1%). A further reduction of mAs to 7.5 mAs caused an increase in the bias of poorly aerated and nonaerated tissue (-2.9% and 2.4%, respectively) and determined a significant widening of the limits of agreement for the same compartments (-10.5% to 4.8% for poorly aerated tissue and -5.9% to 10.8% for nonaerated tissue). Estimated mean effective dose at 140, 60, 15 and 7.5 mAs corresponded to 17.8, 7.4, 2.0 and 0.9 mSv, respectively. Image noise of scans performed at 140, 60, 15 and 7.5 mAs corresponded to 10, 16, 38 and 74 Hounsfield units, respectively. Conclusions A reduction of effective dose up to 70% has been achieved with minimal effects on lung quantitative results. Low-dose computed tomography provides accurate quantitative results and could be used to characterize lung compartment distribution and

    Objective: to study the effect of the postnatal administration of Ambroxol in the prevention of respiratory distress syndrome in preterm neonates at risk and on the severity of the disease in those neonates already suffering from it. Methods: the study was a randomized clinical trial performed on 120 preterm neonates admitted to the neonatal unit of the Suez Canal University Hospital, Egypt, with gestational age of 28 to 34 weeks. It was performed in the period from September 2001 through March 2003. Half of the enrolled neonates received intravenous ambroxol (20 mg/kg/d), while the control group received the routine management of prematurity and a placebo. Results: Ambroxol decreased the incidence of Respiratory Distress Syndrome (RDS), improved the gas exchange, and decreased Continious Positive Airway pressure (CPAP) pressure, the length of mechanical ventilation and also the mortality rate. Conclusion: the study concluded that Ambroxol reduced the incidence of this disease in preterm neonates at risk of developing it, and improved the clinical course of RDS. PMID:21748134

    BACKGROUND: The use of mechanical ventilation to treat respiratory distress syndrome in preterm infants has been associated with the development of bronchopulmonary dysplasia. As part of a quality improvement initiative to reduce the incidence of bronchopulmonary dysplasia in preterm infants, a new practice guideline for the management of respiratory distress syndrome was developed and adopted into practice in a neonatal intensive care unit in February 2012. OBJECTIVE: To evaluate the effects of implementing the new guideline in regard to the use of mechanical ventilation and surfactant, and the incidence of bronchopulmonary dypslasia. METHODS: An historical cohort of very preterm infants (gestational age 260 to 326 weeks) born one year before guideline implementation was compared with a similar cohort of infants born one year following guideline implementation. Data were collected retrospectively from the local neonatal intensive care unit database. RESULTS: A total of 272 preterm infants were included in the study: 129 in the preguideline cohort and 143 in the postguideline cohort. Following the implementation of the guideline, the proportion of infants treated with ongoing mechanical ventilation was reduced from 49% to 26% (P<0.001) and there was a trend toward a reduction in bronchopulmonary dysplasia (27% versus 18%; P=0.07). There was no difference in the proportion of infants treated with surfactant (54% versus 50%). CONCLUSION: The implementation of the practice guideline helped to minimize the use of ongoing mechanical ventilation in preterm infants. PMID:26941562

    Objectives: To investigate two questions in a community based population of people with chronic shoulder pain. Firstly, does chronic pain lead to impaired psychological health over time? Secondly, how does restriction of daily activity influence pain perception and psychological health? Methods: Two postal surveys, two years apart, were carried out to identify a group of subjects with chronic shoulder pain. The first survey was sent to a random sample of adults (n=40026) registered with a primary care practice, and included a pain manikin, demographic information, and the Hospital Anxiety and Depression scale (HAD). The second survey was sent to those subjects who reported unilateral shoulder region pain in the first survey and it included a shoulder-specific disability scale, pain severity score, and the HAD. Results: 2606 (65.1%) people responded to the initial survey. Of these, 304 (11.7%) reported unilateral shoulder region pain at baseline. In the subsequent survey, there were 234 responders (83.3% adjusted response): 142 of these reported shoulder pain and formed our study group of "subjects with chronic shoulder pain". Within this group there was no significant change in psychological distress scores between baseline and follow up. Both the disability score and psychological distress scores correlated significantly with pain severity (disability v pain r=0.536, p<0.001; psychological distress v pain r=0.269, p=0.002). When the correlation between disability and pain severity was corrected for possible confounders, it remained significant (r=0.490, p<0.001). This was not the case for the correlation between psychological distress and pain (p>0.05). Disability was significantly correlated with psychological distress on univariate (r=0.445, p<0.001) and multivariate analysis (r=0.341, p=0.002). Conclusion: In those with chronic shoulder pain the relation between pain and psychological health seems to be linked to disability. Psychological distress was not

    Background and purpose Early or primary application of high-frequency oscillatory ventilation (HFOV) has been recently suggested not to offer benefit to patients with acute respiratory distress syndrome (ARDS). However, the rescue effects of HFOV on severe pediatric acute respiratory distress syndrome (PARDS) with hypoxemia refractory to conventional mechanical ventilation (CMV) remain unclear. This study aimed to determine whether severe PARDS children would benefit from HFOV when oxygenation deteriorated on CMV and to identify any potential risk factors related to mortality. Patients and methods In a retrospective and observational study, 48 children with severe PARDS between January 2009 and July 2015 were divided into two groups: 26 in HFOV group and 22 in CMV group. Data regarding demographic, underlying conditions, arterial blood gases and clinical outcomes were collected and analyzed. Results The arterial partial pressure of oxygen (PaO2)/fraction of inspiration oxygen (FiO2) ratio and PaO2 improved significantly during HFOV, whereas arterial partial pressure of carbon dioxide (PaCO2) and oxygenation index decreased. There was no statistical difference in the in-hospital mortality between the groups (P=0.367). The odds ratio of survival in HFOV group was 2.74 (95% confidence interval 0.52 to 14.58, P=0.237). The pediatric intensive care unit length of stay and total ventilation duration were longer in HFOV group (P=0.048 and P=0.000, respectively). Vasoactive agents were used more frequently in HFOV group (P=0.007). The incidence of new air leak was similar between the two groups (P=0.674). The presence of multiple organ dysfunction syndrome and heavier body weight were identified as predictors of mortality in the HFOV group (P=0.006 and P=0.020, respectively). Conclusion HFOV as an efficient alternative therapy could significantly improve hypoxemia and promote CO2 removal in severe PARDS children when oxygenation progressively worsens on CMV.

    Objective: Acute respiratory distress syndrome (ARDS) is an acute and lethal clinical syndrome that is characterized by hypoxemic respiratory failure and diffuse alveolar inflammatory damage. This review aimed to search and discuss the mass spectrometry (MS)-based proteomic studies on different subsets of ARDS patients. Data Sources: Original research articles were collected from the PubMed database published in English up to December 2015. Study Selection: The literature search was done using the term “(acute lung injury OR acute respiratory distress syndrome) AND (proteomics OR proteome OR mass spectrum OR differential in-gel electrophoresis OR two-dimensional polyacrylamide gel electrophoresis)”. Related original research articles were included and were carefully analyzed. Results: Eight original proteomic researches on ARDS patients were found. The common proteomic modalities were two-dimensional (2D) high-performance liquid chromatography-based electronic spray ion-MS/MS and 2D-polyacrylamide gel electrophoresis/differential in-gel electrophoresis-based matrix-assisted laser desorption ionization-time of flight/MS. They compared the proteome between ARDS patients and normal controls and analyzed the dynamic changes of proteome at different ARDS stages or severity. The disturbed proteome in ARDS patients includes plasma acute-phase proteins, inflammatory/immune-associated proteins, and coagulation proteins. Conclusions: Although several previous studies have provided some useful information about the lung proteome in ARDS patients and gained several interesting disease-associated biomarkers, clinical proteomic studies in ARDS patients are still in the initial stage. An increased cooperation is still needed to establish a global and faithful database containing disease-specific proteome from the largest ARDS subsets. PMID:27647196

  11. Surfactant therapy in preterm infants with respiratory distress syndrome and in near-term or term newborns with acute RDS.

    PubMed

    Ramanathan, R

    2006-05-01

    Many different surfactant preparations derived from animal sources, as well as synthetic surfactants, are available for the treatment of preterm infants with respiratory distress syndrome (RDS). Natural, modified surfactants containing surfactant-associated proteins appear to be more effective than non-protein-containing synthetic surfactants. Comparative trials with poractant alfa at a higher initial dose of 200 mg/kg appear to be associated with rapid weaning of FiO2, less need for additional doses, and decreased mortality in infants <32 weeks gestation when compared with beractant. Early rescue (<30 min of age) surfactant therapy is an effective method to minimize over treatment of some preterm infants who may not develop RDS. Surfactant therapy followed by rapid extubation to nasal ventilation appears to be more beneficial than continued mechanical ventilation. In near-term or term newborns with acute RDS, surfactant therapy has been shown to be 70% effective in improving respiratory failure.

    We present a female patient with severe acute respiratory distress syndrome (ARDS) necessitating intubation and mechanical ventilation on the intensive care unit (ICU). High ventilatory pressures were needed because of hypoxia and severe hypercapnia with respiratory acidosis, resulting in right ventricular dysfunction with impaired haemodynamic stability. A veno-venous extracorporeal CO2 removal (ECCO2R) circuit was initiated, effectively eliminating carbon dioxide while improving oxygenation and enabling a reduction in applied ventilatory pressures. We noted a marked improvement of right ventricular function with restoration of haemodynamic stability. Within one week, the patient was weaned from both ECCO2R and mechanical ventilation. Besides providing adequate gas exchange, extracorporeal assist devices may be helpful in ameliorating right ventricular dysfunction during ARDS.

    This report highlights about one acute respiratory distress syndrome (ARDS) case after near-drowning resuscitated using extracorporeal membrane oxygenation (ECMO). Few cases have been reported about ECMO use for near-drowning and in most of these cases, ECMO was initiated within the first week. However, in our report, we would like to emphasize that seemingly irreversible secondary worsening of ARDS after nearly drowned patient was successfully treated by ECMO use more than 1 week after near-drowning followed by discharge without home oxygen therapy, social support, or any complication. This is probably due to sufficient lung rest for ventilator-associated lung injury during ECMO use. Based on our case's clinical course, intensive care unit physicians must consider ECMO even in the late phase of worsened ARDS after near-drowning.

ARDS was treated with low-level nitric oxide (NO) inhalation (ranging from 4 ppm to 1 ppm) for 24 days. Oxygenation was improved and pulmonary hypertension was reduced after NO inhalation, but systemic blood pressure, heart rate, and cardiac output were not affected. PaO2 improved from 153 Torr to 354 Torr under identical ventilating conditions (F1O2 1.0), and mean pulmonary arterial pressure fell from 40 mm Hg to 27 mmHg. It has been reported that NO inhalation alleviates ventilation-flow mismatch and pulmonary hypertension. It is unclear, however, whether this therapy improves the prognosis for ARDS. In our patient, NO inhalation was effective in alleviating the oxygenation impairment and pulmonary hypertension associated with ARDS.

    Various animal models of lung injury exist to study the complex pathomechanisms of human acute respiratory distress syndrome (ARDS) and evaluate future therapies. Severe lung injury with a reproducible deterioration of pulmonary gas exchange and hemodynamics can be induced in anesthetized pigs using repeated lung lavages with warmed 0.9% saline (50 ml/kg body weight). Including standard respiratory and hemodynamic monitoring with clinically applied devices in this model allows the evaluation of novel therapeutic strategies (drugs, modern ventilators, extracorporeal membrane oxygenators, ECMO), and bridges the gap between bench and bedside. Furthermore, induction of lung injury with lung lavages does not require the injection of pathogens/endotoxins that impact on measurements of pro- and anti-inflammatory cytokines. A disadvantage of the model is the high recruitability of atelectatic lung tissue. Standardization of the model helps to avoid pitfalls, to ensure comparability between experiments, and to reduce the number of animals needed. PMID:27684585

  16. Clinical review: Exogenous surfactant therapy for acute lung injury/acute respiratory distress syndrome - where do we go from here?

    PubMed Central

    2012-01-01

    Acute lung injury and acute respiratory distress syndrome (ARDS) are characterised by severe hypoxemic respiratory failure and poor lung compliance. Despite advances in clinical management, morbidity and mortality remains high. Supportive measures including protective lung ventilation confer a survival advantage in patients with ARDS, but management is otherwise limited by the lack of effective pharmacological therapies. Surfactant dysfunction with quantitative and qualitative abnormalities of both phospholipids and proteins are characteristic of patients with ARDS. Exogenous surfactant replacement in animal models of ARDS and neonatal respiratory distress syndrome shows consistent improvements in gas exchange and survival. However, whilst some adult studies have shown improved oxygenation, no survival benefit has been demonstrated to date. This lack of clinical efficacy may be related to disease heterogeneity (where treatment responders may be obscured by nonresponders), limited understanding of surfactant biology in patients or an absence of therapeutic effect in this population. Crucially, the mechanism of lung injury in neonates is different from that in ARDS: surfactant inhibition by plasma constituents is a typical feature of ARDS, whereas the primary pathology in neonates is the deficiency of surfactant material due to reduced synthesis. Absence of phenotypic characterisation of patients, the lack of an ideal natural surfactant material with adequate surfactant proteins, coupled with uncertainty about optimal timing, dosing and delivery method are some of the limitations of published surfactant replacement clinical trials. Recent advances in stable isotope labelling of surfactant phospholipids coupled with analytical methods using electrospray ionisation mass spectrometry enable highly specific molecular assessment of phospholipid subclasses and synthetic rates that can be utilised for phenotypic characterisation and individualisation of exogenous surfactant

    Acute radiation-induced symptoms reported in survivors after the atomic bombings in Hiroshima and Nagasaki have been suspected to be associated with rain that fell after the explosions, but this association has not been evaluated in an epidemiological study that considers the effects of the direct dose from the atomic bombs and other factors. The aim of this study was to evaluate this association using information from a fixed cohort, comprised of 93,741 members of the Life Span Study who were in the city at the time of the bombing. Information on acute symptoms and exposure to rain was collected in surveys conducted by interviewers, primarily in the 1950s. The proportion of survivors developing severe epilation was around 60% at levels of direct radiation doses of 3 Gy or higher and less than 0.2% at levels <0.005 Gy regardless of reported rain exposure status. The low prevalence of acute symptoms at low direct doses indicates that the reported fallout rain was not homogeneously radioactive at a level sufficient to cause a substantial probability of acute symptoms. We observed that the proportion of reported acute symptoms was slightly higher among those who reported rain exposure in some subgroups, however, suggestions that rain was the cause of these reported symptoms are not supported by analyses specific to the known areas of radioactive fallout. Misclassification of exposure and outcome, including symptoms due to other causes and recall bias, appears to be a more plausible explanation. However, the insufficient and retrospective nature of the available data limited our ability to quantify the attribution to those possible causes.

    In complex multisymptom disorders like fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS) that are defined primarily by subjective symptoms, genetic and gene expression profiles can provide very useful objective information. This paper summarizes research on genes that may be linked to increased susceptibility in developing and maintaining these disorders, and research on resting and stressor-evoked changes in leukocyte gene expression, highlighting physiological pathways linked to stress and distress. These include the adrenergic nervous system, the hypothalamic-pituitary-adrenal axis and serotonergic pathways, and exercise responsive metabolite-detecting ion channels. The findings to date provide some support for both inherited susceptibility and/or physiological dysregulation in all three systems, particularly for catechol-O-methyl transferase (COMT) genes, the glucocorticoid and the related mineralocorticoid receptors (NR3C1, NR3C2), and the purinergic 2X4 (P2X4) ion channel involved as a sensory receptor for muscle pain and fatigue and also in upregulation of spinal microglia in chronic pain models. Methodological concerns for future research, including potential influences of comorbid clinical depression and antidepressants and other medications, on gene expression are also addressed.

    Thirty-seven survivors completed the Impact of Event Scale (IES), a measure of intrusive and avoidant activity, at around 3 yr following the Herald of Free Enterprise disaster. The aim of the present study was to examine the relationship between scores on the IES to scores on the Beck Depression Inventory (BDI) and the Spielberger State Anxiety Inventory (STAI-Y1) at around 5 yr subsequent to the event. Higher scores on the IES were able to predict higher scores on the BDI and the STAI-Y1 over and above scores on the 28-item General Health Questionnaire (GHQ-28) which was also administered at around 3 yr on from the event. Implications for cognitive-behaviour therapy are discussed.

    Psychological distress is a known feature of generalized joint hypermobility (gJHM), as well as of its most common syndromic presentation, namely Ehlers-Danlos syndrome, hypermobility type (a.k.a. joint hypermobility syndrome - JHS/EDS-HT), and significantly contributes to the quality of life of affected individuals. Most published articles dealt with the link between gJHM (or JHS/EDS-HT) and anxiety-related conditions, and a novel generation of studies is emerging aimed at investigating the psychopathologic background of such an association. In this paper, literature review was carried out with a semi-systematic approach spanning the entire spectrum of psychopathological findings in gJHM and JHS/EDS-HT. Interestingly, in addition to the confirmation of a tight link between anxiety and gJHM, preliminary connections with depression, attention deficit (and hyperactivity) disorder, autism spectrum disorders, and obsessive-compulsive personality disorder were also found. Few papers investigated the relationship with schizophrenia with contrasting results. The mind-body connections hypothesized on the basis of available data were discussed with focus on somatotype, presumed psychopathology, and involvement of the extracellular matrix in the central nervous system. The hypothesis of positive Beighton score and alteration of interoceptive/proprioceptive/body awareness as possible endophenotypes in families with symptomatic gJHM or JHS/EDS-HT is also suggested. Concluding remarks addressed the implications of the psychopathological features of gJHM and JHS/EDS-HT in clinical practice.

    To clarify the mechanism of leukemogenesis in atomic bomb survivors, leukemic cells were investigated using fluorescence in situ hybridization (FISH) analysis on the basis of conventional G-banding in patients with a history of radiation exposure and also in de novo patients. Conventional G-banding showed higher incidences (p < 0.005) of structural and numerical abnormalities without any specific types of chromosome aberrations in the group exposed to a dose of more than one Gy, compared to the non-exposed group. FISH analysis revealed significantly higher incidences (P < 0.05) of subclones with monosomy 7 and deletion of the 20q13.2 region, which were not found in conventional cytogenetic analysis in the exposed group (more than one Gy) compared to the non-exposed controls. Furthermore, segmental jumping translocation (SJT) of the c-MYC gene region was observed only in the exposed group. These chromosomal instability suggested that the leukemic cells from the heavily exposed patients contained persistent cellular genetic instability which may strongly influence the development of leukemia in people exposed to radiation.

    Cancer and its treatment exert a heavy psychological and physical toll. Of the myriad symptoms which result, pain is common, encountered in between 30% and 60% of cancer survivors. Pain in cancer survivors is a major and growing problem, impeding the recovery and rehabilitation of patients who have beaten cancer and negatively impacting on cancer patients' quality of life, work prospects and mental health. Persistent pain in cancer survivors remains challenging to treat successfully. Pain can arise both due to the underlying disease and the various treatments the patient has been subjected to. Chemotherapy causes painful chemotherapy-induced peripheral neuropathy (CIPN), radiotherapy can produce late effect radiation toxicity and surgery may lead to the development of persistent post-surgical pain syndromes. This review explores a selection of the common causes of persistent pain in cancer survivors, detailing our current understanding of the pathophysiology and outlining both the clinical manifestations of individual pain states and the treatment options available.

    Acute Respiratory Distress Syndrome (ARDS) severity may be influenced by heterogeneity of neutrophil activation. Interferon-stimulated genes (ISG) are a broad gene family induced by Type I interferons, often as a response to viral infections, which evokes extensive immunomodulation. We tested the hypothesis that over- or under-expression of immunomodulatory ISG by neutrophils is associated with worse clinical outcomes in patients with ARDS. Genome-wide transcriptional profiles of circulating neutrophils isolated from patients with sepsis-induced ARDS (n = 31) and healthy controls (n = 19) were used to characterize ISG expression. Hierarchical clustering of expression identified 3 distinct subject groups with Low, Mid and High ISG expression. ISG accounting for the greatest variability in expression were identified (MX1, IFIT1, and ISG15) and used to analyze a prospective cohort at the Colorado ARDS Network site. One hundred twenty ARDS patients from four urban hospitals were enrolled within 72 hours of initiation of mechanical ventilation. Circulating neutrophils were isolated from patients and expression of ISG determined by PCR. Samples were stratified by standard deviation from the mean into High (n = 21), Mid, (n = 82) or Low (n = 17) ISG expression. Clinical outcomes were compared between patients with High or Low ISG expression to those with Mid-range expression. At enrollment, there were no differences in age, gender, co-existing medical conditions, or type of physiologic injury between cohorts. After adjusting for age, race, gender and BMI, patients with either High or Low ISG expression had significantly worse clinical outcomes than those in the Mid for number of 28-day ventilator- and ICU-free days (P = 0.0006 and 0.0004), as well as 90-day mortality and 90-day home with unassisted breathing (P = 0.02 and 0.004). These findings suggest extremes of ISG expression by circulating neutrophils from ARDS patients recovered early in the syndrome are associated

    Administration of endotracheal surfactant is potentially the main treatment for neonates suffering from RDS (Respiratory Distress Syndrome), which is followed by mechanical ventilation. Late and severe complications may develop as a consequence of using mechanical ventilation. In this study, conventional methods for treatment of RDS are compared with surfactant administration, use of mechanical ventilation for a brief period and NCPAP (Nasal Continuous Positive Airway Pressure), (INSURE method ((Intubation, Surfactant administration and extubation)). A randomized clinical trial study was performed, including all newborn infants with diagnosed RDS and a gestational age of 35 weeks or less, who were admitted in NICU of Valiasr hospital. The patients were then divided randomly into two CMV (Conventional Mechanical Ventilation) and INSURE groups. Surfactant administration and consequent long-term mechanical ventilation were done in the first group (CMV group). In the second group (INSURE group), surfactant was administered followed by a short-term period of mechanical ventilation. The infants were then extubated, and NCPAP was embedded. The comparison included crucial duration of mechanical ventilation and oxygen therapy, IVH (Intraventricular Hemorrhage), PDA (Patent Ductus Arteriosus), air-leak syndromes, BPD (Broncho-Pulmonary Dysplasia) and mortality rate. The need for mechanical ventilation in 5th day of admission was 43% decreased (P=0.005) in INSURE group in comparison to CMV group. A decline (P=0.01) in the incidence of IVH and PDA was also achieved. Pneumothorax, chronic pulmonary disease and mortality rates, were not significantly different among two groups. (P=0.25, P=0.14, P=0.25, respectively). This study indicated that INSURE method in the treatment of RDS decreases the need for mechanical ventilation and oxygen-therapy in preterm neonates. Moreover, relevant complications as IVH and PDA were observed to be reduced. Thus, it seems rationale to perform

    2006-01-01

    Background Management of acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU) is clinically challenging and costly. Neuromuscular blocking agents may facilitate mechanical ventilation and improve oxygenation, but may result in prolonged recovery of neuromuscular function and acute quadriplegic myopathy syndrome (AQMS). The goal of this study was to address a hypothetical question via computer modeling: Would a reduction in intubation time of 6 hours and/or a reduction in the incidence of AQMS from 25% to 21%, provide enough benefit to justify a drug with an additional expenditure of $267 (the difference in acquisition cost between a generic and brand name neuromuscular blocker)? Methods The base case was a 55 year-old man in the ICU with ARDS who receives neuromuscular blockade for 3.5 days. A Markov model was designed with hypothetical patients in 1 of 6 mutually exclusive health states: ICU-intubated, ICU-extubated, hospital ward, long-term care, home, or death, over a period of 6 months. The net monetary benefit was computed. Results Our computer simulation modeling predicted the mean cost for ARDS patients receiving standard care for 6 months to be $62,238 (5% – 95% percentiles $42,259 – $83,766), with an overall 6-month mortality of 39%. Assuming a ceiling ratio of $35,000, even if a drug (that cost $267 more) hypothetically reduced AQMS from 25% to 21% and decreased intubation time by 6 hours, the net monetary benefit would only equal $137. Conclusion ARDS patients receiving a neuromuscular blocker have a high mortality, and unpredictable outcome, which results in large variability in costs per case. If a patient dies, there is no benefit to any drug that reduces ventilation time or AQMS incidence. A prospective, randomized pharmacoeconomic study of neuromuscular blockers in the ICU to asses AQMS or intubation times is impractical because of the highly variable clinical course of patients with ARDS.

    Since mechanical ventilation can cause harm to lung tissue it should be as protective as possible. Whereas numerous options exist to set ventilator parameters, an adequate monitoring is lacking up to date. The Electrical Impedance Tomography (EIT) provides a non-invasive visualization of ventilation which is relatively easy to apply and commercially available. Although there are a number of published measures and parameters derived from EIT, it is not clear how to use EIT to improve clinical outcome of e.g. patients suffering from acute respiratory distress syndrome (ARDS), a severe disease with a high mortality rate. On the one hand, parameters should be easy to obtain, on the other hand clinical algorithms should consider them to optimize ventilator settings. The so called Global inhomogeneity (GI) index bases on the fact that ARDS is characterized by an inhomogeneous injury pattern. By applying positive endexpiratory pressures (PEEP), homogeneity should be attained. In this study, ARDS was induced by a double hit procedure in six pigs. They were randomly assigned to either the EIT or the control group. Whereas in the control group the ARDS network table was used to set the PEEP according to the current inspiratory oxygen fraction, in the EIT group the GI index was calculated during a decremental PEEP trial. PEEP was kept when GI index was lowest. Interestingly, PEEP was significantly higher in the EIT group. Additionally, two of these animals died ahead of the schedule. Obviously, not only homogeneity of ventilation distribution matters but also limitation of over-distension.

    Background Antiplatelet agents are commonly used for cardiovascular diseases, but their pleiotropic effects in critically ill patients are controversial. We therefore performed a meta-analysis of cohort studies to investigate the effect of antiplatelet therapy in the critically ill. Methods Nine cohort studies, retrieved from PubMed and Embase before November 2015, involving 14,612 critically ill patients and 4765 cases of antiplatelet users, were meta-analysed. The main outcome was hospital or 30-day mortality. Secondary outcome was acute respiratory distress syndrome (ARDS) or acute lung injury (ALI). Random- or fixed-effect models were taken for quantitative synthesis of the data. Results Antiplatelet therapy was associated with decreased mortality (odds ratio (OR) 0.61; 95% confidence interval (CI), 0.52–0.71; I2 = 0%; P <0. 001) and ARDS/ALI (OR 0.64; 95% CI, 0.50–0.82; I2 = 0%; P <0. 001). In every stratum of subgroups, similar findings on mortality reduction were consistently observed in critically ill patients. Conclusions Antiplatelet therapy is associated with reduced mortality and lower incidence of ARDS/ALI in critically ill patients, particularly those with predisposing conditions such as high-risk surgery, trauma, pneumonia, and sepsis. However, it remains unclear whether similar findings can be observed in the unselected and broad population with critical illness. PMID:27182704

  14. A new horizon for the use of non-invasive ventilation in patients with acute respiratory distress syndrome

    PubMed Central

    2016-01-01

    Non-invasive ventilation (NIV) has assumed an important role in the management of acute respiratory failure (ARF). NIV, compared with standard medical therapy, improves survival and reduces complications in selected patients with ARF. NIV represents the first-line intervention for some forms of ARF, such as chronic obstructive pulmonary disease (COPD) exacerbations and acute cardiogenic pulmonary edema. The use of NIV is also well supported for immunocompromised patients who are at high risk for infectious complications from endotracheal intubation. Selection of appropriate patients is crucial for optimizing NIV success rates. Appropriate ventilator settings, a well-fitting and comfortable interface, and a team skilled and experienced in managing NIV are key components to its success. In a recent issue of the Journal of the American Medical Association, Patel et al. reported the results of their single-center trial of 83 patients with acute respiratory distress syndrome (ARDS) who were randomly assigned to NIV delivered via a helmet or face mask. Patients assigned to the helmet group exhibited a significantly lower intubation rate and were more likely to survive through 90 days. This perspective reviews the findings of this trial in the context of current clinical practice and in light of data from the literature focused on the potential reasons for success of NIV delivered through a helmet compared to face mask. The implications for early management of patients with ARDS are likewise discussed. PMID:27761452

    The ARDS Network low-tidal-volume protocol is considered the standard of care for patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). The protocol is built on the foundation of low-tidal-volume ventilation, use of a combined PEEP and F(IO(2)) table, and managing alveolar end-inspiratory pressure by limiting the plateau airway pressure to ≤ 30 cm H(2)O. Although this strategy, to date, is the only method that significantly improves ALI/ARDS survival, alternative methods of improving hypoxemia and minimizing ventilator-induced lung injury, in conjunction with low-tidal-volume ventilation, can be used for life-threatening ARDS. We present a case in which we customized the use of alveolar recruitment maneuvers by analyzing the hysteresis of the pressure-volume curve to assess lung recruitability, decremental PEEP to sustain lung recruitment, and careful use of plateau pressure ≥ 30 cm H(2)O, which improved our patient's life-threatening hypoxemia within the first 36 min of arrival to our ICU.

    Extracorporeal membrane oxygenation (ECMO) is increasingly being used to treat severe acute respiratory distress syndrome (ARDS). However, there is limited clinical evidence about how to optimize the technique. Experimental research can provide an alternative to fill the actual knowledge gap. The purpose of the present study was to develop and validate an animal model of acute lung injury (ALI) which resembled severe ARDS, and which could be successfully supported with ECMO. Eighteen pigs were randomly allocated into three groups: sham, ALI, and ALI + ECMO. ALI was induced by a double-hit consisting in repeated saline lavage followed by a 2-hour period of injurious ventilation. All animals were followed up to 24 hours while being ventilated with conventional ventilation (tidal volume 10 ml/kg). The lung injury model resulted in severe hypoxemia, increased airway pressures, pulmonary hypertension, and altered alveolar membrane barrier function, as indicated by an increased protein concentration in bronchoalveolar fluid, and increased wet/dry lung weight ratio. Histologic examination revealed severe diffuse alveolar damage, characteristic of ARDS. Veno-venous ECMO was started at the end of lung injury induction with a flow > 60 ml/kg/min resulting in rapid reversal of hypoxemia and pulmonary hypertension. Mortality was 0, 66.6 and 16.6% in the SHAM, ALI and ALI + ECMO groups, respectively (p < 0.05). This is a novel clinically relevant animal model that can be used to optimize the approach to ECMO and foster translational research in extracorporeal lung support. PMID:27398166

    Lipoid pneumonia usually presents after chronic recurrent ingestion of oily substances or accidental aspiration during "fire-eating" demonstrations. Massive exposure by near drowning extremely rare and potentially fatal. We present here a case of survival after total immersion in oil in her workplace. A 66-year-old woman who nearly drowned in a vat of vegetable oil was admitted as an emergency case with severe hypoxia after rescue. Chest computed tomography (CT) findings showed bilateral ground-glass opacity, consolidation, and the case fulfilled the criteria for acute respiratory distress syndrome (ARDS). Bronchoscopy and bronchoalveolar lavage performed on admission indicated oil droplets and marked neutrophilia (67%), which made us diagnose ARDS induced by lipoid pneumonia. We commenced treatment with pulsed steroids and strictly managed fluid balance under mechanical ventilation. Despite immediate improvement in oxygenation, the value of extravascular lung water index (EVLWI) measured by the PiCCO system consistently remained over 30 ml/Kg through her clinical course. We concluded that lipoid pneumonia is characterized by prolonged elevatation of pulmonary vascular permeability.

    Acute respiratory distress syndrome (ARDS) is a severe pulmonary reaction requiring hospitalization, which is incited by many causes, including bacterial and viral pneumonia as well as near drowning, aspiration of gastric contents, pancreatitis, intravenous drug use, and abdominal trauma. In humans, ARDS is very well defined by a list of clinical parameters. However, until recently no consensus was available regarding the criteria of ARDS that should be evident in an experimental animal model. This lack was rectified by a 2011 workshop report by the American Thoracic Society, which defined the main features proposed to delineate the presence of ARDS in laboratory animals. These should include histological changes in parenchymal tissue, altered integrity of the alveolar capillary barrier, inflammation, and abnormal pulmonary function. Murine ARDS models typically are defined by such features as pulmonary edema and leukocyte infiltration in cytological preparations of bronchoalveolar lavage fluid and/or lung sections. Common pathophysiological indicators of ARDS in mice include impaired pulmonary gas exchange and histological evidence of inflammatory infiltrates into the lung. Thus, morphological endpoints remain a vital component of data sets assembled from animal ARDS models.

  19. Equipoise in Research and the Development of Neonatal Interventions for the Management of Respiratory Distress Syndrome: A Historical Perspective.

    2015-08-01

    The historical review of how evidence was developed for the management of respiratory distress syndrome in premature infants has not been clearly characterized. Knowledge of this process is essential to understand the role of equipoise and its influence on the decision to evaluate interventions as they were implemented in the practice of medicine. We suspect that errant approaches to clinical equipoise secondary to states of false certainty and false uncertainty have been important barriers to the timely acquisition and implementation of evidence-based knowledge necessary to improve outcomes in this fragile population of infants. When confronted with the decision to test an intervention, physicians should question whether they have lost clinical equipoise based on opinion, expertise, or observational data rather than evidence obtained from methodological inquiry; doing so facilitates reaching clinical equipoise and promotes the application of scientific methodology to answer relevant clinical questions. Timely acquisition of evidence-based knowledge can be viewed as an ethical imperative when the status quo may have negative consequences on outcomes for generations.

    The present study was undertaken to determine whether acute respiratory distress syndrome (ARDS) is produced after Mesobuthus tamulus (MBT) envenomation and compared it with oleic acid (OA)-induced ARDS. The trachea, jugular vein and femoral artery were cannulated in anesthetized adult rats. Lethal dose of MBT venom (5 mg/kg) or OA (75 μL) was administered intravenously and the time-dependent changes in respiratory frequency (RF), heart rate (HR) and mean arterial pressure (MAP) were recorded. Minute ventilation (MV) and the PaO2/FiO2 (P/F) ratio were also determined. At the end lungs were excised, one lung was used for histopathological examination and the other was used for determination of pulmonary water content physically. MBT venom or OA produced hypoxemia, pulmonary pathology (alveolar damage, infiltration of inflammatory cells, capillary damage and exudation) and pulmonary edema implicating for ARDS. However, the hypoxemia in MBT venom group was associated with decreased MV, apnea/bradypnea, and bradycardia whereas, in OA group it was seen with increased MV, tachypnea, and tachycardia. Lack of effect of hypoxemic drive on RF/MV or HR in MBT venom group unlike OA group, suggests the involvement of medullary centers. The present results demonstrate that MBT venom produces ARDS. However MBT venom-induced ARDS involves pulmonary as well as extrapulmonary mechanisms.

    Both quality improvement and clinical research efforts over the past few decades have focused on consensus definition of sepsis and acute respiratory distress syndrome (ARDS). Although clinical definitions based on readily available clinical data have advanced recognition and timely use of broad supportive treatments, they likely hinder the identification of more targeted therapies that manipulate select biological mechanisms underlying critical illness. Sepsis and ARDS are by definition heterogeneous, and patients vary in both their underlying biology and their severity of illness. We have long been able to identify subtypes of sepsis and ARDS that confer different prognoses. The key is that we are now on the verge of identifying subtypes that may confer different response to therapy. In this perspective, inspired by a 2015 American Thoracic Society International Conference Symposium entitled "Lumpers and Splitters: Phenotyping in Critical Illness," we highlight promising approaches to uncovering patient subtypes that may predict treatment responsiveness and not just differences in prognosis. We then discuss how this information can be leveraged to improve the success and translatability of clinical trials by using predictive enrichment and other design strategies. Last, we discuss the challenges and limitations to identifying biomarkers and endotypes and incorporating them into routine clinical practice. PMID:27244481

    Acute respiratory distress syndrome (ARDS) is a serious medical condition occurring in patients with polytrauma, pulmonary or non-pulmonary sepsis, pneumonia and many other circumstances. It causes inflammation of the lung parenchyma leading to impaired gas exchange with a systemic release of inflammatory mediators, causing consequential lung tissue injury, hypoxemia and frequently multiple organ failure. The aim of current study was to describe expression of inflammatory markers (myeloperoxidase, CD163 and vascular endothelial growth factor) by the cells in acute phase of ARDS. The lung samples of a 20-year-old man who had suffered a serious motorbike accident were obtained for histological examination. He died on the seventh day as a consequence of respiratory failure. Our results imply that expression of CD163 was restricted to activated alveolar macrophages and monocytes. Immunopositivityof MPO was observed in neutrophil granulocytes within lung alveoli and lung blood vessels. Myeloperoxidase positivity was observed in alveolar macrophages, too. Vascular endothelial growth factor was expressed in cytoplasm of neutrophil granulocytes, monocytes, small-sized alveolar macrophages and type II pneumocytes localized mostly inside lung alveoli. On the contrary, no positivity was observed in lung endothelial cells of blood vessels. PMID:25120850

    The purpose of this study was to compare the Berlin definition to the American-European Consensus Conference (AECC) definition in determining the prevalence of acute respiratory distress syndrome (ARDS) and associated mortality in the critically ill burn population. Consecutive patients admitted to our institution with burn injury that required mechanical ventilation for more than 24 hours were included for analysis. Included patients (N = 891) were classified by both definitions. The median age, % TBSA burn, and injury severity score (interquartile ranges) were 35 (24-51), 25 (11-45), and 18 (9-26), respectively. Inhalation injury was present in 35.5%. The prevalence of ARDS was 34% using the Berlin definition and 30.5% using the AECC definition (combined acute lung injury and ARDS), with associated mortality rates of 40.9 and 42.9%, respectively. Under the Berlin definition, mortality rose with increased ARDS severity (14.6% no ARDS; 16.7% mild; 44% moderate; and 59.7% severe, P < 0.001). By contrast, under the AECC definition increased mortality was seen only for ARDS category (14.7% no ARDS; 15.1% acute lung injury; and 46.0% ARDS, P < 0.001). The mortality of the 22 subjects meeting the AECC, but not the Berlin definition was not different from patients without ARDS (P = .91). The Berlin definition better stratifies ARDS in terms of severity and correctly excludes those with minimal disease previously captured by the AECC.

    Cerebellar injury is increasingly recognized as an important complication of very preterm birth. However, the neurodevelopmental consequences of early life cerebellar injury in prematurely born infants have not been well elucidated. We performed a literature search of studies published between 1997 and 2014 describing neurodevelopmental outcomes of preterm infants following direct cerebellar injury or indirect cerebellar injury/underdevelopment. Available data suggests that both direct and indirect mechanisms of cerebellar injury appear to stunt cerebellar growth and adversely affect neurodevelopment. This review also provides important insights into the highly integrated cerebral-cerebellar structural and functional correlates. Finally, this review highlights that early life impairment of cerebellar growth extends far beyond motor impairments and plays a critical, previously underrecognized role in the long-term cognitive, behavioral, and social deficits associated with brain injury among premature infants. These data point to a developmental form of the cerebellar cognitive affective syndrome previously described in adults. Longitudinal prospective studies using serial advanced magnetic resonance imaging techniques are needed to better delineate the full extent of the role of prematurity-related cerebellar injury and topography in the genesis of cognitive, social-behavioral dysfunction.

    BACKGROUND: There is little knowledge regarding the association between psychological factors and complex regional pain syndrome (CRPS) in children. Specifically, it is not known which factors precipitate CRPS and which result from the ongoing painful disease. OBJECTIVES: To examine symptoms of depression and anxiety as well as the experience of stressful life events in children with CRPS compared with children with chronic primary headaches and functional abdominal pain. METHODS: A retrospective chart study examined children with CRPS (n=37) who received intensive inpatient pain treatment between 2004 and 2010. They were compared with two control groups (chronic primary headaches and functional abdominal pain; each n=37), who also received intensive inpatient pain treatment. Control groups were matched with the CRPS group with regard to admission date, age and sex. Groups were compared on symptoms of depression and anxiety as well as stressful life events. RESULTS: Children with CRPS reported lower anxiety and depression scores compared with children with abdominal pain. A higher number of stressful life events before and after the onset of the pain condition was observed for children with CRPS. CONCLUSIONS: Children with CRPS are not particularly prone to symptoms of anxiety or depression. Importantly, children with CRPS experienced more stressful life events than children with chronic headaches or abdominal pain. Prospective long-term studies are needed to further explore the potential role of stressful life events in the etiology of CRPS. PMID:26035287

    In 1981, the Spanish toxic oil syndrome (TOS) affected more than 20,000 people, and over 300 deaths were registered. Assessment of genetic polymorphisms on xenobiotic metabolism would indicate the potential metabolic capacity of the victims at the time of the disaster. Thus, impaired metabolic pathways may have contributed to the clearance of the toxicant(s) leading to a low detoxification or accumulation of toxic metabolites contributing to the disease. We conducted a matched case-control study using 72 cases (54 females, 18 males) registered in the Official Census of Affected Patients maintained by the Spanish government. Controls were nonaffected siblings (n =72) living in the same household in 1981 and nonaffected nonrelatives (n = 70) living in the neighborhood at that time, with no ties to TOS. Genotype analyses were performed to assess the metabolic capacity of phase I [cytochrome P450 1A1 (CYP1A1), CYP2D6] and phase II [arylamine N-acetyltransferase-2 (NAT2), GSTM1 (glutathione S-transferase M1) and GSTT1] enzyme polymorphisms. The degree of association of the five metabolic pathways was estimated by calculating their odds ratios (ORs) using conditional logistic regression analysis. In the final model, cases compared with siblings (72 pairs) showed no differences either in CYP2D6 or CYP1A1 polymorphisms, or in conjugation enzyme polymorphisms, whereas cases compared with the unrelated controls (70 pairs) showed an increase in NAT2 defective alleles [OR = 6.96, 95% confidence interval (CI), 1.46-33.20] adjusted by age and sex. Glutathione transferase genetic polymorphisms (GSTM1, GSTT1) showed no association with cases compared with their siblings or unrelated controls. These findings suggest a possible role of impaired acetylation mediating susceptibility in TOS. PMID:11335185

    Malaria-associated acute lung injury (MA-ALI) and its more severe form malaria-associated acute respiratory distress syndrome (MA-ARDS) are common, often fatal complications of severe malaria infections. However, little is known about their pathogenesis. In this study, biochemical alterations of the lipid composition of the lungs were investigated as possible contributing factors to the severity of murine MA-ALI/ARDS. C57BL/6J mice were infected with Plasmodium berghei NK65 to induce lethal MA-ARDS, or with Plasmodium chabaudi AS, a parasite strain that does not induce lung pathology. The lipid profile of the lung tissue from mice infected with Plasmodium berghei NK65 developing MA-ALI/ARDS, but not that from mice without lung pathology or controls, was characterized by high levels of phospholipids -mainly phosphatidylcholine- and esterified cholesterol. The high levels of polyunsaturated fatty acids and the linoleic/oleic fatty acid ratio of the latter reflect the fatty acid composition of plasma cholesterol esters. In spite of the increased total polyunsaturated fatty acid pool, which augments the relative oxidability of the lung membranes, and the presence of hemozoin, a known pro-oxidant, no excess oxidative stress was detected in the lungs of Plasmodium berghei NK65 infected mice. The bronchoalveolar lavage (BAL) fluid of Plasmodium berghei NK65 infected mice was characterized by high levels of plasma proteins. The phospholipid profile of BAL large and small aggregate fractions was also different from uninfected controls, with a significant increase in the amounts of sphingomyelin and lysophosphatidylcholine and the decrease in phosphatidylglycerol. Both the increase of proteins and lysophosphatidylcholine are known to decrease the intrinsic surface activity of surfactant. Together, these data indicate that an altered lipid composition of lung tissue and BAL fluid, partially ascribed to oedema and lipoprotein infiltration, is a characteristic feature of murine

  10. Exploring the heterogeneity of effects of corticosteroids on acute respiratory distress syndrome: a systematic review and meta-analysis

    PubMed Central

    2014-01-01

    Introduction The effectiveness of corticosteroid therapy on the mortality of acute respiratory distress syndrome (ARDS) remains under debate. We aimed to explore the grounds for the inconsistent results in previous studies and update the evidence. Methods We searched MEDLINE, Cochrane Central Register of Controlled Trials and Web of Science up to December 2013. Eligible studies included randomized clinical trials (RCTs) and cohort studies that reported mortality and that had corticosteroid nonusers for comparison. The effect of corticosteroids on ARDS mortality was assessed by relative risk (RR) and risk difference (RD) for ICU, hospital, and 60-day mortality using a random-effects model. Results Eight RCTs and 10 cohort studies were included for analysis. In RCTs, corticosteroids had a possible but statistically insignificant effect on ICU mortality (RD, −0.28; 95% confidence interval (CI), −0.53 to −0.03 and RR, 0.55; 95% CI, 0.24 to 1.25) but no effect on 60-day mortality (RD, −0.01; 95% CI, −0.12 to 0.10 and RR, 0.97; 95% CI, 0.75 to 1.26). In cohort studies, corticosteroids had no effect on ICU mortality (RR, 1.05; 95% CI, 0.74 to 1.49) but non-significantly increased 60-day mortality (RR, 1.30; 95% CI, 0.96 to 1.78). In the subgroup analysis by ARDS etiology, corticosteroids significantly increased mortality in influenza-related ARDS (three cohort studies, RR, 2.45, 95% CI, 1.40 to 4.27). Conclusions The effects of corticosteroids on the mortality of ARDS differed by duration of outcome measures and etiologies. Corticosteroids did not improve longer-term outcomes and may cause harm in certain subgroups. Current data do not support routine use of corticosteroids in ARDS. More clinical trials are needed to specify the favorable and unfavorable subgroups for corticosteroid therapy. PMID:24708846

    Most cases of severe influenza are associated with pulmonary complications, such as acute respiratory distress syndrome (ARDS), and no antiviral drugs of proven value for treating such complications are currently available. The use of monoclonal antibodies targeting the stem of the influenza virus surface hemagglutinin (HA) is a rapidly developing strategy for the control of viruses of multiple HA subtypes. However, the mechanisms of action of these antibodies are not fully understood, and their ability to mitigate severe complications of influenza has been poorly studied. We evaluated the effect of treatment with VIS410, a human monoclonal antibody targeting the HA stem region, on the development of ARDS in BALB/c mice after infection with influenza A(H7N9) viruses. Prophylactic administration of VIS410 resulted in the complete protection of mice against lethal A(H7N9) virus challenge. A single therapeutic dose of VIS410 given 24 h after virus inoculation resulted in dose-dependent protection of up to 100% of mice inoculated with neuraminidase inhibitor-susceptible or -resistant A(H7N9) viruses. Compared to the outcomes in mock-treated controls, a single administration of VIS410 improved viral clearance from the lungs, reduced virus spread in lungs in a dose-dependent manner, resulting in a lower lung injury score, reduced the extent of the alteration in lung vascular permeability and protein accumulation in bronchoalveolar lavage fluid, and improved lung physiologic function. Thus, antibodies targeting the HA stem can reduce the severity of ARDS and show promise as agents for controlling pulmonary complications in influenza. PMID:26787699

    Despite multiple advances in critical care patients with severe adult respiratory distress syndrome (ARDS) can exhaust the capability of conventional ventilation; this results in respiratory failure and death. High-frequency percussive ventilation (HFPV), which was initially utilized for salvage of burn patients with smoke inhalation injury refractory to conventional ventilation, has evolved as a standard of burn care. Based on our experience with HFPV in burn patients the burn team was consulted to provide salvage ventilation for non-burn surgical intensive care unit patients with refractory respiratory failure. Over a 14-month period ten patients with refractory ARDS from multiple causes were treated. Retrospective chart review was performed. Respiratory parameters were assessed before and 24 hours after initiation of HFPV. Mean values of fraction of inspired oxygen (FiO2), pH, partial pressure of O2 in arterial blood (PaO2), partial pressure of CO2 in arterial blood (PaCO2), HCO3, oxygen saturation in arterial blood (SaO2), PaO2/FiO2, and peak inspiratory pressure were compared. Significant improvement in oxygenation was reflected by increases in SaO2, PaO2, and the PaO2/FiO2 ratio in the first 24 hours of HFPV. No significant increase in peak inspiratory pressure was documented by conversion from conventional ventilation to HFPV. No hemodynamic changes directly associated with HFPV were noted. Seven of ten patients failing conventional ventilation survived to hospital discharge after salvage therapy with HFPV. We advocate further studies of HFPV in non-burn patients with ARDS both as salvage therapy and as replacement for conventional ventilation for the initial treatment for ARDS.

    Objectives: To assess the relation between cigarette smoking during pregnancy and neonatal respiratory distress syndrome (RDS) in very preterm birth, and to analyse the differential effect of antenatal steroids on RDS among smokers and non-smokers. Design: A population based cohort study (the French Epipage study). Setting: Regionally defined births in France. Methods: A total of 858 very preterm liveborn singletons (27–32 completed weeks of gestation) of the French Epipage study were included in this analysis. The odds ratio for RDS in relation to smoking in pregnancy was estimated using a logistic regression to control for gestational age. The odds ratio for RDS in relation to antenatal steroids was estimated taking into account an interaction between antenatal steroids and cigarette smoking, using multiple logistic regression to control for gestational age, birthweight ratio, main causes of preterm birth, mode of delivery, and sex. Results: The odds ratio for RDS in relation to smoking in pregnancy adjusted for gestational age (aOR) was 0.59 (95% confidence interval (CI) 0.44 to 0.79). The aOR for RDS in relation to antenatal steroids was 0.31 (95% CI 0.19 to 0.49) in babies born to non-smokers and 0.63 (95% CI 0.38 to 1.05) in those born to smokers; the difference was significant (p = 0.04). Conclusions: Cigarette smoking during pregnancy is associated with a decrease in the risk of RDS in very preterm babies. Although antenatal steroids reduce the risk of RDS in babies born to both smokers and non-smokers, the reduction is smaller in those born to smokers. PMID:15613572

    Mechanical ventilation (MV) and oxygen therapy (hyperoxia; HO) comprise the cornerstones of life-saving interventions for patients with acute respiratory distress syndrome (ARDS). Unfortunately, the side effects of MV and HO include exacerbation of lung injury by barotrauma, volutrauma, and propagation of lung inflammation. Despite significant improvements in ventilator technologies and a heightened awareness of oxygen toxicity, besides low tidal volume ventilation few if any medical interventions have improved ARDS outcomes over the past two decades. We are lacking a comprehensive understanding of mechanotransduction processes in the healthy lung and know little about the interactions between simultaneously activated stretch-, HO-, and cytokine-induced signaling cascades in ARDS. Nevertheless, as we are unraveling these mechanisms we are gathering increasing evidence for the importance of stretch-activated ion channels (SACs) in the activation of lung-resident and inflammatory cells. In addition to the discovery of new SAC families in the lung, e.g., two-pore domain potassium channels, we are increasingly assigning mechanosensing properties to already known Na(+), Ca(2+), K(+), and Cl(-) channels. Better insights into the mechanotransduction mechanisms of SACs will improve our understanding of the pathways leading to ventilator-induced lung injury and lead to much needed novel therapeutic approaches against ARDS by specifically targeting SACs. This review 1) summarizes the reasons why the time has come to seriously consider SACs as new therapeutic targets against ARDS, 2) critically analyzes the physiological and experimental factors that currently limit our knowledge about SACs, and 3) outlines the most important questions future research studies need to address.

    Background In the period immediately after birth, preterm infants are highly susceptible to lung injury. Early nasal continuous positive airway pressure (ENCPAP) is an attempt to avoid intubation and may minimize lung injury. In contrast, ENCPAP can fail, and at that time surfactant rescue can be less effective. Objective To compare the pulmonary clinical course and outcome of very preterm infants (gestational age 25–32 weeks) with respiratory distress syndrome (RDS) who started with ENCPAP and failed (ECF group), with a control group of infants matched for gestational age, who were directly intubated in the delivery room (DRI group). Primary outcome consisted of death during admission or bronchopulmonary dysplasia (BPD). Results 25 infants were included in the ECF group and 50 control infants matched for gestational age were included in the DRI group. Mean gestational age and birth weight in the ECF group were 29.7 weeks and 1,393 g and in the DRI group 29.1 weeks and 1,261 g (p = NS). The incidence of BPD was significantly lower in the ECF group than in the DRI group (4% vs. 35%; P<0.004; OR 12.6 (95% CI 1.6–101)). Neonatal mortality was similar in both groups (4%). The incidence of neonatal morbidities such as severe cerebral injury, patent ductus arteriosus, necrotizing enterocolitis and retinopathy of prematurity, was not significantly different between the two groups. Conclusion A trial of ENCPAP at birth may reduce the incidence of BPD and does not seem to be detrimental in very preterm infants. Randomized controlled trials are needed to test whether early respiratory management of preterm infants with RDS plays an important role in the development of BPD. PMID:17285145

    Background. Positive end-expiratory pressure (PEEP) is widely used to improve oxygenation and prevent alveolar collapse in mechanically ventilated patients with the acute respiratory distress syndrome (ARDS). Although PEEP improves arterial oxygenation predictably, high-PEEP strategies have demonstrated equivocal improvements in ARDS-related mortality. The effect of PEEP on tissue oxygen delivery is poorly understood and is difficult to quantify or investigate in the clinical environment. Methods. We investigated the effects of PEEP on tissue oxygen delivery in ARDS using a new, high-fidelity, computational model with highly integrated respiratory and cardiovascular systems. The model was configured to replicate published clinical trial data on the responses of 12 individual ARDS patients to changes in PEEP. These virtual patients were subjected to increasing PEEP levels during a lung-protective ventilation strategy (0–20 cm H2O). Measured variables included arterial oxygenation, cardiac output, peripheral oxygen delivery, and alveolar strain. Results. As PEEP increased, tissue oxygen delivery decreased in all subjects (mean reduction of 25% at 20 cm H2O PEEP), despite an increase in arterial oxygen tension (mean increase 6.7 kPa at 20 cm H2O PEEP). Changes in arterial oxygenation and tissue oxygen delivery differed between subjects but showed a consistent pattern. Static and dynamic alveolar strain decreased in all patients as PEEP increased. Conclusions. Incremental PEEP in ARDS appears to protect alveoli and improve arterial oxygenation, but also appears to impair tissue oxygen delivery significantly because of reduced cardiac output. We propose that this trade-off may explain the poor improvements in mortality associated with high-PEEP ventilation strategies. PMID:27799180

    ABSTRACT Background: Over 32% of burned battlefield causalities develop trauma-induced hypoxic respiratory failure, also known as acute respiratory distress syndrome (ARDS). Recently, 9 out of 10 US combat soldiers’ survived life-threatening trauma-induced ARDS supported with extracorporeal membrane oxygenation (ECMO), a portable form of cardiopulmonary bypass. Unfortunately, the size, incidence of coagulation complications, and the need for systematic anticoagulation for traditional ECMO devices have prevented widespread use of this lifesaving technology. Therefore, a compact, mobile, ECMO system using minimal anticoagulation may be the solution to reduce ARDS in critically ill military and civilian patients. Methods: We conducted a prospective cohort laboratory investigation to evaluate the coagulation function in an ovine model of oleic acid induced ARDS supported with veno-venous ECMO. The experimental design approximated the time needed to transport from a battlefield setting to an advanced facility and compared bolus versus standard heparin anticoagulation therapy. Results: Comprehensive coagulation and hemostasis assays did not show any difference because of ECMO support over 10 h between the two groups but did show changes because of injury. Platelet count and function did decrease with support on ECMO, but there was no significant bleeding or clot formation during the entire experiment. Conclusions: A bolus heparin injection is sufficient to maintain ECMO support for up to 10 h in an ovine model of ARDS. With a reduced need for systematic anticoagulation, ECMO use for battlefield trauma could reduce significant morbidity and mortality from ventilator-induced lung injury and ARDS. Future studies will investigate the mechanisms and therapies to support patients for longer periods on ECMO without coagulation complications. Level of Evidence: V—therapeutic animal experiment.

    Malaria-associated acute lung injury (MA-ALI) and its more severe form malaria-associated acute respiratory distress syndrome (MA-ARDS) are common, often fatal complications of severe malaria infections. However, little is known about their pathogenesis. In this study, biochemical alterations of the lipid composition of the lungs were investigated as possible contributing factors to the severity of murine MA-ALI/ARDS. C57BL/6J mice were infected with Plasmodium berghei NK65 to induce lethal MA-ARDS, or with Plasmodium chabaudi AS, a parasite strain that does not induce lung pathology. The lipid profile of the lung tissue from mice infected with Plasmodium berghei NK65 developing MA-ALI/ARDS, but not that from mice without lung pathology or controls, was characterized by high levels of phospholipids -mainly phosphatidylcholine- and esterified cholesterol. The high levels of polyunsaturated fatty acids and the linoleic/oleic fatty acid ratio of the latter reflect the fatty acid composition of plasma cholesterol esters. In spite of the increased total polyunsaturated fatty acid pool, which augments the relative oxidability of the lung membranes, and the presence of hemozoin, a known pro-oxidant, no excess oxidative stress was detected in the lungs of Plasmodium berghei NK65 infected mice. The bronchoalveolar lavage (BAL) fluid of Plasmodium berghei NK65 infected mice was characterized by high levels of plasma proteins. The phospholipid profile of BAL large and small aggregate fractions was also different from uninfected controls, with a significant increase in the amounts of sphingomyelin and lysophosphatidylcholine and the decrease in phosphatidylglycerol. Both the increase of proteins and lysophosphatidylcholine are known to decrease the intrinsic surface activity of surfactant. Together, these data indicate that an altered lipid composition of lung tissue and BAL fluid, partially ascribed to oedema and lipoprotein infiltration, is a characteristic feature of murine

    Most cases of severe influenza are associated with pulmonary complications, such as acute respiratory distress syndrome (ARDS), and no antiviral drugs of proven value for treating such complications are currently available. The use of monoclonal antibodies targeting the stem of the influenza virus surface hemagglutinin (HA) is a rapidly developing strategy for the control of viruses of multiple HA subtypes. However, the mechanisms of action of these antibodies are not fully understood, and their ability to mitigate severe complications of influenza has been poorly studied. We evaluated the effect of treatment with VIS410, a human monoclonal antibody targeting the HA stem region, on the development of ARDS in BALB/c mice after infection with influenza A(H7N9) viruses. Prophylactic administration of VIS410 resulted in the complete protection of mice against lethal A(H7N9) virus challenge. A single therapeutic dose of VIS410 given 24 h after virus inoculation resulted in dose-dependent protection of up to 100% of mice inoculated with neuraminidase inhibitor-susceptible or -resistant A(H7N9) viruses. Compared to the outcomes in mock-treated controls, a single administration of VIS410 improved viral clearance from the lungs, reduced virus spread in lungs in a dose-dependent manner, resulting in a lower lung injury score, reduced the extent of the alteration in lung vascular permeability and protein accumulation in bronchoalveolar lavage fluid, and improved lung physiologic function. Thus, antibodies targeting the HA stem can reduce the severity of ARDS and show promise as agents for controlling pulmonary complications in influenza. PMID:26787699

    We assessed the changes in regional lung function following instillation of surfactant in a model of respiratory distress syndrome (RDS) induced by whole lung lavage and mechanical ventilation in eight anaesthetized, paralyzed, and mechanically ventilated New Zealand White rabbits. Regional specific ventilation (sV̇) was measured by K-edge subtraction synchrotron computed tomography during xenon washin. Lung regions were classified as poorly aerated (PA), normally aerated (NA), or hyperinflated (HI) based on regional density. A functional category was defined within each class based on sV̇ distribution (High, Normal, and Low). Airway resistance (Raw), respiratory tissue damping (G), and elastance (H) were measured by forced oscillation technique at low frequencies before and after whole lung saline lavage-induced (100 ml/kg) RDS, and 5 and 45 min after intratracheal instillation of beractant (75 mg/kg). Surfactant instillation improved Raw, G, and H (P < 0.05 each), and gas exchange and decreased atelectasis (P < 0.001). It also significantly improved lung aeration and ventilation in atelectatic lung regions. However, in regions that had remained normally aerated after lavage, it decreased regional aeration and increased sV̇ (P < 0.001) and sV̇ heterogeneity. Although surfactant treatment improved both central airway and tissue mechanics and improved regional lung function of initially poorly aerated and atelectatic lung, it deteriorated regional lung function when local aeration was normal prior to administration. Local mechanical and functional heterogeneity can potentially contribute to the worsening of RDS and gas exchange. These data underscore the need for reassessing the benefits of routine prophylactic vs. continuous positive airway pressure and early "rescue" surfactant therapy in very immature infants.

    The objective of this study was to determine if newborn premature infants with severe respiratory distress syndrome (RDS) who developed bronchopulmonary dysplasia (BPD) demonstrate, within the first 3 days of life, lower blood levels of antioxidants and higher urine levels of lipid peroxidation products than premature infants who recovered from RDS. Perinatal variables (gestational age, birth weight, and Apgar scores) and antioxidant indices in cord and in third day of life plasma and red blood cell (RBC) samples from healthy premature infants (n = 35), infants with RDS (n = 23) and infants with BPD (n = 23) were examined. Antioxidant indices included selenium, alpha-tocopherol, total and oxidized glutathione, glutathione peroxidase, superoxide dismutase, and urinary malondialdehyde. By inferential statistics, only the perinatal variables and cord plasma selenium distinguished healthy premature infants from premature infants with RDS or BPD. From perinatal variables and antioxidant indices we calculated: (1) cord to third-day-of-life variable differences, (2) variable-to-variable ratios, and (3) ratios of a difference for one variable to a difference for any second variable. Subset regression analysis yielded an equation (adjusted R2 = 0.8839) that correctly predicted infants who developed BPD 100% of the time. Predictor variables for BPD were gestational age, Apgar at 1 min, cord and third-day-of-life RBC selenium, cord total glutathione, cord and third-day-of-life glutathione peroxidase and nine different ratios involving Apgar scores, RBC selenium, total and oxidized glutathione, alpha-tocopherol, glutathione peroxidase, and superoxide dismutase. In this study, there was no relationship between lipid peroxidation and BPD. There was a higher rate of patent ductus arteriosus, congestive heart failure, and retinopathy of prematurity in infants with BPD. This study confirms that low plasma selenium and alpha-tocopherol levels in premature infants (< or = 30 weeks

    Respiratory-distress syndrome (RDS) in the newborn is a major cause of neonatal mortality and morbidity. Although prematurity is the most-important risk factor for RDS, the syndrome does not develop in many premature infants. The main cause of RDS is a deficiency of pulmonary surfactant, which consists of phospholipids and specific proteins. The genes underlying susceptibility to RDS are insufficiently known. The candidate-gene approach was used to study the association between the surfactant protein A (SP-A) gene locus and RDS in the genetically homogeneous Finnish population. In the present study, 88 infants with RDS and 88 control infants that were matched for degree of prematurity, prenatal glucocorticoid therapy, and sex were analyzed for SP-A genotypes. We show that certain SP-A1 alleles (6A2 and 6A3) and an SP-A1/SP-A2 haplotype (6A2/1A0) were associated with RDS. The 6A2 allele was overrepresented and the 6A3 allele was underrepresented in infants with RDS. These associations were particularly strong among small premature infants born at gestational age <32 wk. In infants protected from RDS (those that had no RDS, despite extreme prematurity and lack of glucocorticoid therapy), compared with infants that had RDS develop despite having received glucocorticoid therapy, the frequencies of 6A2 (.22 vs.71), 6A3 (.72 vs.17), 6A2/1A0 (.17 vs.68), 6A3/1A1 (.39 vs.10), and 6A3/1A2 (.28 vs.06) in the two groups, respectively, were strikingly different. According to the results of conditional logistic-regression analysis, diseases associated with premature birth did not explain the association between the odds of a particular homozygous SP-A1 genotype (6A2/6A2 and 6A3/6A3) and RDS. In the population evaluated in the present study, SP-B intron 4 variant frequencies were low and had no detectable association with RDS. We conclude that the SP-A gene locus is an important determinant for predisposition to RDS in premature infants. PMID:10762543

    Newborn respiratory distress presents a diagnostic and management challenge. Newborns with respiratory distress commonly exhibit tachypnea with a respiratory rate of more than 60 respirations per minute. They may present with grunting, retractions, nasal flaring, and cyanosis. Common causes include transient tachypnea of the newborn, respiratory distress syndrome, meconium aspiration syndrome, pneumonia, sepsis, pneumothorax, persistent pulmonary hypertension of the newborn, and delayed transition. Congenital heart defects, airway malformations, and inborn errors of metabolism are less common etiologies. Clinicians should be familiar with updated neonatal resuscitation guidelines. Initial evaluation includes a detailed history and physical examination. The clinician should monitor vital signs and measure oxygen saturation with pulse oximetry, and blood gas measurement may be considered. Chest radiography is helpful in the diagnosis. Blood cultures, serial complete blood counts, and C-reactive protein measurement are useful for the evaluation of sepsis. Most neonates with respiratory distress can be treated with respiratory support and noninvasive methods. Oxygen can be provided via bag/mask, nasal cannula, oxygen hood, and nasal continuous positive airway pressure. Ventilator support may be used in more severe cases. Surfactant is increasingly used for respiratory distress syndrome. Using the INSURE technique, the newborn is intubated, given surfactant, and quickly extubated to nasal continuous positive airway pressure. Newborns should be screened for critical congenital heart defects via pulse oximetry after 24 hours but before hospital discharge. Neonatology consultation is recommended if the illness exceeds the clinician's expertise and comfort level or when the diagnosis is unclear in a critically ill newborn. PMID:26760414

    Physiologic changes that lead to the development of ARDS begin with the precipitating shock syndrome. Hypovolemia, pulmonary vasoconstriction, reduced myocardial performance, and diminished O2 transport typically precede the development of clinical ARDS after hemorrhage, trauma, postoperative conditions, and sepsis. Since shock lung is a complication of shock, it is not surprising that the antecedent clinical and physiologic events that characterize the shock state may be determinants of both the genesis and the outcome of ARDS. Postoperative ARDS follows unrecognized or inadequately treated hypovolemia and hypoxia during an antecedent period of preoperative or intraoperative shock. Hypovolemia and hypoxia increase cardiac and ventilatory drive and stimulate neurohumoral mechanisms to increase pulmonary vasoconstriction. The last-named, when extensive and uneven, produces maldistribution of flow and reduces DO2 and VO2. Subsequently, mediator-induced pulmonary vasoconstriction increases the problem. When sufficiently extensive, these antecedent physiologic alterations culminate in ARDS. With impaired flow and O2 transport, pathogenic mechanisms of ARDS and acute renal failure may be set in motion; further, the naturally occurring immune mechanisms may be impaired and may lead to associated infection. There are at least six redistributions that are major pathophysiologic influences in ARDS. They are uneven ventilation throughout the lung; redistribution of regional pulmonary blood flow between zones due to gravity; nonuniform pulmonary blood flow between individual metarteriolar-capillary networks because of local vasoconstriction; uneven systemic blood flow between organs; irregular systemic blood flow at the microcirculatory level, producing inadequate nutritional flow to the tissues; and redistribution of body water, leading particularly to fluid accumulation in the extracellular compartment, with expanded interstitial space and contracted plasma volume

    Objective The goal of this research was to examine the extent to which 10-year breast cancer survivors integrated cancer into their self-concept (i.e., survivor centrality), identify predictors of survivor centrality, and determine the relation of survivor centrality to well-being. Methods Breast cancer survivors (n = 240) were interviewed 10 years following the initial diagnosis. They completed measures of survivor centrality, illness valence (i.e., positive or negative views of illness), and well-being (positive and negative affect, mental and physical functioning, psychological distress, benefit-finding). Results There were few predictors of the kinds of women who were more likely to integrate breast cancer into their self-concepts, but survivor centrality was related to engaging in behaviors that suggested survivorship was relevant to women’s daily lives, such as becoming involved in breast cancer activities. Survivor centrality was related to three markers of negative psychological well-being: more negative affect, poorer mental functioning, and greater psychological distress. However, in the case of negative affect and psychological distress, this relation was moderated by illness valence, such that survivor centrality was only related to negative psychological well-being when the illness was viewed in less positive terms. Conclusions Women vary in the extent to which they define themselves in terms of the breast cancer experience. Survivor centrality in and of itself is not always indicative of adjustment to disease. When women have a more negative view of being a breast cancer survivor, survivor centrality is more likely to signify potential problems. PMID:20878844

    Coupled plasma filtration adsorption (CPFA) is an extracorporeal blood purification therapy based on non-specific pro- and anti-inflammatory mediator adsorption on a special resin cartridge coupled with continuous veno-venous haemofiltration or continuous veno-venous haemodiafiltration and is one of the emerging treatments for septic patients. However, in the literature, there are limited data about its efficacy in treating patients with acute diseases but without the traditional criteria for sepsis. We describe the case of a 43-year-old male who developed acute respiratory distress syndrome secondary to pneumonia and acute kidney injury, whose clinical conditions rapidly improved after early CPFA therapy.

    Most epidemiological studies of acute respiratory distress syndrome (ARDS) have been conducted in western countries, and studies in Asia are limited. The aim of our study was to evaluate the incidence, in-hospital mortality, and 1-year mortality of ARDS in Taiwan.We conducted a nationwide inpatient cohort study based on the Taiwan National Health Insurance Research Database between 1997 and 2011. A total of 40,876 ARDS patients (68% male; mean age 66 years) were identified by International Classification of Diseases, 9th edition coding and further analyzed for clinical characteristics, medical costs, and mortality.The overall crude incidence of ARDS was 15.74 per 100,000 person-years, and increased from 2.53 to 19.26 per 100,000 person-years during the study period. The age-adjusted incidence of ARDS was 15.19 per 100,000 person-years. The overall in-hospital mortality was 57.8%. In-hospital mortality decreased from 59.7% in 1997 to 47.5% in 2011 (P < 0.001). The in-hospital mortality rate was lowest (33.5%) in the youngest patients (age 18-29 years) and highest (68.2%) in the oldest patients (>80 years, P < 0.001). The overall 1-year mortality rate was 72.1%, and decreased from 75.8% to 54.7% during the study period. Patients who died during hospitalization were older (69 ± 17 versus 62 ± 19, P < 0.001) and predominantly male (69.8% versus 65.3%, P < 0.001). In addition, patients who died during hospitalization had significantly higher medical costs (6421 versus 5825 US Dollars, P < 0.001) and shorter lengths of stay (13 versus 19 days, P < 0.001) than patients who survived.We provide the first large-scale epidemiological analysis of ARDS incidence and outcomes in Asia. Although the overall incidence was lower than has been reported in a prospective US study, this may reflect underdiagnosis by International Classification of Diseases, 9th edition code and identification of only patients with more severe ARDS in this analysis

    Background & objectives: Despite advances in therapy and overall medical care, acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) management remains a problem. Hence the objective of this study was to develop a rat model that mimics human ALI/ARDS. Methods: Four groups of Wistar rats, 48 per group were treated with (i) intratracheal (IT) lipopolysaccharide (LPS) (5 mg/kg) dissolved in normal saline (NS), (ii) intravenous (iv) oleic acid (OA) (250 μl/kg) suspension in bovine serum albumin (BSA), (iii) dual hit: IT LPS (2 mg/kg) dissolved in NS and iv OA (100 μl/kg) and (iv) control group: IT NS and iv BSA. From each group at set periods of time various investigations like chest X-rays, respiratory rate (RR), tidal volume (TV), total cell count, differential cell count, total protein count and cytokine levels in bronchoalveolar lavage fluid (BALF), lung wet/dry weight ratio and histopathological examination were done. Results: It was noted that the respiratory rate, and tumour necrosis factor-α (TNF-α) levels were significantly higher at 4 h in the dual hit group as compared to LPS, OA and control groups. Interleukin-6 (IL-6) levels were significantly higher in the dual hit group as compared to LPS at 8 and 24 h, OA at 8 h and control (at all time intervals) group. IL-1β levels were significantly higher in LPS and dual hit groups at all time intervals, but not in OA and control groups. The injury induced in dual hit group was earlier and more sustained as compared to LPS and OA alone. Interpretation & conclusions: The lung pathology and changes in respiration functions produced by the dual hit model were closer to the diagnostic criteria of ALI/ARDS in terms of clinical manifestations and pulmonary injury and the injury persisted longer as compared to LPS and OA single hit model. Therefore, the ARDS model produced by the dual hit method was closer to the diagnostic criteria of ARDS in terms of clinical manifestations and pulmonary injury. PMID

    Introduction Apoptosis of neutrophils (polymorphonuclear neutrophils [PMNs]) may limit inflammatory injury in sepsis and acute respiratory distress syndrome (ARDS), but the relationship between the severity of sepsis and extent of PMN apoptosis and the effect of superimposed ARDS is unknown. The objective of this study was to correlate neutrophil apoptosis with the severity of sepsis and sepsis-induced ARDS. Methods A prospective cohort study was conducted in intensive care units of three tertiary hospitals in Porto Alegre, southern Brazil. Fifty-seven patients with sepsis (uncomplicated sepsis, septic shock, and sepsis-induced ARDS) and 64 controls were enrolled. Venous peripheral blood was collected from patients with sepsis within 24 hours of diagnosis. All surgical groups, including controls, had their blood drawn 24 hours after surgery. Control patients on mechanical ventilation had blood collected within 24 hours of initiation of mechanical ventilation. Healthy controls were blood donors. Neutrophils were isolated, and incubated ex vivo, and apoptosis was determined by light microscopy on cytospun preparations. The differences among groups were assessed by analysis of variance with Tukeys. Results In medical patients, the mean percentage of neutrophil apoptosis (± standard error of the mean [SEM]) was lower in sepsis-induced ARDS (28% ± 3.3%; n = 9) when compared with uncomplicated sepsis (57% ± 3.2%; n = 8; p < 0.001), mechanical ventilation without infection, sepsis, or ARDS (53% ± 3.0%; n = 11; p < 0.001) and healthy controls (69% ± 1.1%; n = 33; p < 0.001) but did not differ from septic shock (38% ± 3.7%; n = 12; p = 0.13). In surgical patients with sepsis, the percentage of neutrophil apoptosis was lower for all groups when compared with surgical controls (52% ± 3.6%; n = 11; p < 0.001). Conclusion In medical patients with sepsis, neutrophil apoptosis is inversely proportional to the severity of sepsis and thus may be a marker of the severity of

    Necrosis amplifies inflammation and plays important roles in acute respiratory distress syndrome (ARDS). Necroptosis is a newly identified programmed necrosis that is mediated by receptor interacting protein 3 (RIP3). However, the potential involvement and impact of necroptosis in lipopolysaccharide (LPS)-induced ARDS remains unknown. We therefore explored the role and mechanism of RIP3-mediated necroptosis in LPS-induced ARDS. Mice were instilled with increasing doses of LPS intratracheally to induce different degrees of ARDS. Lung tissues were harvested for histological and TUNEL staining and western blot for RIP3, p-RIP3, X-linked inhibitor of apoptosis protein (XIAP), mixed lineage kinase domain-like protein (MLKL), total and cleaved caspases-3/8. Then, wild-type and RIP3 knock-out mice were induced ARDS with 30 mg/kg LPS. Pulmonary cellular necrosis was labeled by the propidium Iodide (PI) staining. Levels of TNF-a, Interleukin (IL)-1β, IL-6, IL-1α, IL-10 and HMGB1, tissue myeloperoxidase (MPO) activity, neutrophil counts and total protein concentration were measured. Results showed that in high dose LPS (30mg/kg and 40mg/kg) -induced severe ARDS, RIP3 protein was increased significantly, accompanied by increases of p-RIP3 and MLKL, while in low dose LPS (10mg/kg and 20mg/kg) -induced mild ARDS, apoptosis was remarkably increased. In LPS-induced severe ARDS, RIP3 knock-out alleviated the hypothermia symptom, increased survival rate and ameliorated the lung tissue injury RIP3 depletion also attenuated LPS-induced increase in IL-1α/β, IL-6 and HMGB1 release, decreased tissue MPO activity, and reduced neutrophil influx and total protein concentration in BALF in severe ARDS. Further, RIP3 depletion reduced the necrotic cells in the lung and decreased the expression of MLKL, but had no impact on cleaved caspase-3 in LPS-induced ARDS. It is concluded that RIP3-mediated necroptosis is a major mechanism of enhanced inflammation and lung tissue injury in high dose

    The aim of this study was to compare three ventilatory techniques for reducing PaCO2 in patients with severe acute respiratory distress syndrome treated with permissive hypercapnia: (1) expiratory washout alone at a flow of 15 L/min, (2) optimized mechanical ventilation defined as an increase in the respiratory frequency to the maximal rate possible without development of intrinsic positive end- expiratory pressure (PEEP) combined with a reduction of the instrumental dead space, and (3) the combination of both methods. Tidal volume was set according to the pressure-volume curve in order to obtain an inspiratory plateau airway pressure equal to the upper inflection point minus 2 cm H2O after setting the PEEP at 2 cm H2O above the lower inflection point and was kept constant throughout the study. The three modalities were compared at the same inspiratory plateau airway pressure through an adjustment of the extrinsic PEEP. During conventional mechanical ventilation using a respiratory frequency of 18 breaths/min, respiratory acidosis (PaCO2 = 84 +/- 24 mm Hg and pH = 7.21 +/- 0.12) was observed. Expiratory washout and optimized mechanical ventilation (respiratory frequency of 30 +/- 4 breaths/min) had similar effects on CO2 elimination (DeltaPaCO2 = -28 +/- 11% versus -27 +/- 12%). A further decrease in PaCO2 was observed when both methods were combined (DeltaPaCO2 = -46 +/- 7%). Extrinsic PEEP had to be reduced by 5.3 +/- 2.1 cm H2O during expiratory washout and by 7.3 +/- 1.3 cm H2O during the combination of the two modes, whereas it remained unchanged during optimized mechanical ventilation alone. In conclusion, increasing respiratory rate and reducing instrumental dead space during conventional mechanical ventilation is as efficient as expiratory washout to reduce PaCO2 in patients with severe ARDS and permissive hypercapnia. When used in combination, both techniques have additive effects and result in PaCO2 levels close to normal values. PMID:10390383

  14. Albumin versus crystalloid solutions in patients with the acute respiratory distress syndrome: a systematic review and meta-analysis

    2014-01-01

    Introduction In patients with acute respiratory distress syndrome (ARDS) fluid therapy might be necessary. The aim of this systematic review and meta-analysis is to determine the effects of colloid therapy compared to crystalloids on mortality and oxygenation in adults with ARDS. Methods Randomized controlled trials (RCTs) were identified through a systematic literature search of MEDLINE, EMBASE, CENTRAL and LILACS. Articles published up to 15th February 2013 were independently screened, abstracted, and assessed (Cochrane Risk of Bias Tool) to provide evidence-based therapy recommendations. RCTs were eligible if they compared colloid versus crystalloid therapy on lung function, inflammation, damage or mortality in adults with ARDS. Primary outcome parameters were respiratory mechanics, gas exchange lung inflammation and damage as well as hospital mortality. Kidney function, need for renal replacement therapy, hemodynamic stabilization and intensive care unit (ICU) length of stay served as secondary outcomes. Results A total of 3 RCTs out of 4130 potential trials found in the databases were selected for qualitative and quantitative analysis totaling 206 patients who received either albumin or saline. Overall risk of bias was unclear to high in the identified trials. Calculated pooled risk of death was not statistically significant (albumin 34 of 100 (34.0%) versus 40 of 104 (38.5%), relative risk (RR) = 0.89, 95% confidence interval (CI) 0.62 to 1.28, P = 0.539). Weighted mean difference (WMD) in PaO2/FiO2 (mmHg) improved in the first 48 hours (WMD = 62, 95% CI 47 to 77, P <0.001, I2 = 0%) after therapy start and remained stable after 7 days (WMD = 20, 95% CI 4 to 36, P = 0.017, I2 = 0%). Conclusions There is a high need for RCTs investigating the effects of colloids in ARDS patients. Based on the findings of this review, colloid therapy with albumin improved oxygenation but did not affect mortality. PMID:24405693

    Most epidemiological studies of acute respiratory distress syndrome (ARDS) have been conducted in western countries, and studies in Asia are limited. The aim of our study was to evaluate the incidence, in-hospital mortality, and 1-year mortality of ARDS in Taiwan.We conducted a nationwide inpatient cohort study based on the Taiwan National Health Insurance Research Database between 1997 and 2011. A total of 40,876 ARDS patients (68% male; mean age 66 years) were identified by International Classification of Diseases, 9th edition coding and further analyzed for clinical characteristics, medical costs, and mortality.The overall crude incidence of ARDS was 15.74 per 100,000 person-years, and increased from 2.53 to 19.26 per 100,000 person-years during the study period. The age-adjusted incidence of ARDS was 15.19 per 100,000 person-years. The overall in-hospital mortality was 57.8%. In-hospital mortality decreased from 59.7% in 1997 to 47.5% in 2011 (P < 0.001). The in-hospital mortality rate was lowest (33.5%) in the youngest patients (age 18-29 years) and highest (68.2%) in the oldest patients (>80 years, P < 0.001). The overall 1-year mortality rate was 72.1%, and decreased from 75.8% to 54.7% during the study period. Patients who died during hospitalization were older (69 ± 17 versus 62 ± 19, P < 0.001) and predominantly male (69.8% versus 65.3%, P < 0.001). In addition, patients who died during hospitalization had significantly higher medical costs (6421 versus 5825 US Dollars, P < 0.001) and shorter lengths of stay (13 versus 19 days, P < 0.001) than patients who survived.We provide the first large-scale epidemiological analysis of ARDS incidence and outcomes in Asia. Although the overall incidence was lower than has been reported in a prospective US study, this may reflect underdiagnosis by International Classification of Diseases, 9th edition code and identification of only patients with more severe ARDS in this analysis

    Objective: Currently, the method of early nasal continuous positive airway pressure (nCPAP) and selective administration of surfactant via an endotracheal tube is widely used in the treatment of respiratory distress syndrome (RDS) in premature infants. To prevent complications related to endotracheal intubation and even a brief period of mechanical ventilation, in this study, we compared the effectiveness of surfactant administration via a thin intratracheal catheter versus the current method using an endotracheal tube. Methods: Thirty eight preterm infants ≤34 weeks' gestation with birth weight of 1000–1800 g who were putted on nCPAP for RDS within the first hour of life, were randomly assigned to receive surfactant either via endotracheal tube (ET group) or via thin intratracheal catheter (CATH group). The primary outcomes were the need for mechanical ventilation and duration of oxygen therapy. Data were analyzed by independent t-test, Mann-Whitney U-test, and Chi-square test, using SPSS v. 21. Findings: There was no significant difference between groups regarding to need for mechanical ventilation during the first 72 h of birth (3 [15.8%] in ET group vs. 2 [10.5%] in CATH group; P = 0.99). Duration of oxygen therapy in CATH group was significantly lower than ET group (243.7 ± 74.3 h vs. 476.8 ± 106.8 h, respectively; P = 0.018). The incidence of adverse events during all times of surfactant administration was not statistically significant between groups (P = 0.14), but the number of infants who experienced adverse events during surfactant administration was significantly lower in CATH group than ET group (6 [31.6%] vs. 12 [63.2%], respectively; P = 0.049). All other outcomes, including duration of treatment with CPAP and mechanical ventilation, times of surfactant administration and the need for more than one dose of the drug, the rate of intraventricular hemorrhage, mortality and combined outcome of chronic lung disease or mortality were statistically

    Acute respiratory distress syndrome (ARDS) is acute lung failure secondary to severe systemic inflammation, resulting in a derangement of alveolar mechanics (i.e. the dynamic change in alveolar size and shape during tidal ventilation), leading to alveolar instability that can cause further damage to the pulmonary parenchyma. Mechanical ventilation is a mainstay in the treatment of ARDS, but may induce mechano-physical stresses on unstable alveoli, which can paradoxically propagate the cellular and molecular processes exacerbating ARDS pathology. This phenomenon is called ventilator induced lung injury (VILI), and plays a significant role in morbidity and mortality associated with ARDS. In order to identify optimal ventilation strategies to limit VILI and treat ARDS, it is necessary to understand the complex interplay between biological and physical mechanisms of VILI, first at the alveolar level, and then in aggregate at the whole-lung level. Since there is no current consensus about the underlying dynamics of alveolar mechanics, as an initial step we investigate the ventilatory dynamics of an alveolar sac (AS) with the lung alveolar spatial model (LASM), a 3D spatial biomechanical representation of the AS and its interaction with airflow pressure and the surface tension effects of pulmonary surfactant. We use the LASM to identify the mechanical ramifications of alveolar dynamics associated with ARDS. Using graphical processing unit parallel algorithms, we perform Bayesian inference on the model parameters using experimental data from rat lung under control and Tween-induced ARDS conditions. Our results provide two plausible models that recapitulate two fundamental hypotheses about volume change at the alveolar level: (1) increase in alveolar size through isotropic volume change, or (2) minimal change in AS radius with primary expansion of the mouth of the AS, with the implication that the majority of change in lung volume during the respiratory cycle occurs in the

    Acute respiratory distress syndrome (ARDS) continues to have significant mortality and morbidity. The only intervention proven to reduce mortality is the use of lung-protective mechanical ventilation strategies, although such a strategy may lead to problematic hypercapnia. Extracorporeal carbon dioxide removal (ECCO₂R) devices allow uncoupling of ventilation from oxygenation, thereby removing carbon dioxide and facilitating lower tidal volume ventilation. We performed a systematic review to assess efficacy, complication rates, and utility of ECCO₂R devices. We included randomised controlled trials (RCTs), case-control studies and case series with 10 or more patients. We searched MEDLINE, Embase, LILACS (Literatura Latino Americana em Ciências da Saúde), and ISI Web of Science, in addition to grey literature and clinical trials registries. Data were independently extracted by two reviewers against predefined criteria and agreement was reached by consensus. Outcomes of interest included mortality, intensive care and hospital lengths of stay, respiratory parameters and complications. The review included 14 studies with 495 patients (two RCTs and 12 observational studies). Arteriovenous ECCO₂R was used in seven studies, and venovenous ECCO₂R in seven studies. Available evidence suggests no mortality benefit to ECCO₂R, although post hoc analysis of data from the most recent RCT showed an improvement in ventilator-free days in more severe ARDS. Organ failure-free days or ICU stay have not been shown to decrease with ECCOvR. Carbon dioxide removal was widely demonstrated as feasible, facilitating the use of lower tidal volume ventilation. Complication rates varied greatly across the included studies, representing technological advances. There was a general paucity of high-quality data and significant variation in both practice and technology used among studies, which confounded analysis. ECCO₂R is a rapidly evolving technology and is an efficacious treatment

    The effects of the combination of a 'lowest' lung ventilation with extracorporeal elimination of carbon dioxide by interventional lung assist are described in a patient presenting with severe acute respiratory distress syndrome due to fulminant pneumonia. Reducing tidal volume to 3 ml.kg(-1) together with interventional lung assist resulted in a decrease in severe hypercapnia without alveolar collapse or hypoxaemia but with a decrease in serum levels of interleukin-6. This approach was applied for 12 days with recovery of the patient, without complications. Extracorporeal removal of carbon dioxide by interventional lung assist may be a useful tool to enable 'ultraprotective' ventilation in severe acute respiratory distress syndrome.

  3. Randomized controlled trial to evaluate the effects of combined progressive exercise on metabolic syndrome in breast cancer survivors: rationale, design, and methods

    PubMed Central

    2014-01-01

    Background Metabolic syndrome (MetS) is increasingly present in breast cancer survivors, possibly worsened by cancer-related treatments, such as chemotherapy. MetS greatly increases risk of cardiovascular disease and diabetes, co-morbidities that could impair the survivorship experience, and possibly lead to cancer recurrence. Exercise has been shown to positively influence quality of life (QOL), physical function, muscular strength and endurance, reduce fatigue, and improve emotional well-being; however, the impact on MetS components (visceral adiposity, hyperglycemia, low serum high-density lipoprotein cholesterol, hypertriglyceridemia, and hypertension) remains largely unknown. In this trial, we aim to assess the effects of combined (aerobic and resistance) exercise on components of MetS, as well as on physical fitness and QOL, in breast cancer survivors soon after completing cancer-related treatments. Methods/Design This study is a prospective randomized controlled trial (RCT) investigating the effects of a 16-week supervised progressive aerobic and resistance exercise training intervention on MetS in 100 breast cancer survivors. Main inclusion criteria are histologically-confirmed breast cancer stage I-III, completion of chemotherapy and/or radiation within 6 months prior to initiation of the study, sedentary, and free from musculoskeletal disorders. The primary endpoint is MetS; secondary endpoints include: muscle strength, shoulder function, cardiorespiratory fitness, body composition, bone mineral density, and QOL. Participants randomized to the Exercise group participate in 3 supervised weekly exercise sessions for 16 weeks. Participants randomized to the Control group are offered the same intervention after the 16-week period of observation. Discussion This is the one of few RCTs examining the effects of exercise on MetS in breast cancer survivors. Results will contribute a better understanding of metabolic disease-related effects of resistance and

    Mortality from acute respiratory distress syndrome (ARDS) has gone down recently. In spite of this trend, the absolute numbers continue to be high even with improvements in ventilator strategies and a better understanding of fluid management with this disease. A possible reason for this could be an under-recognized involvement of the pulmonary vasculature and the right side of the heart in ARDS. The right heart is not designed to function under situations leading to acute elevations in afterload as seen in ARDS, and hence it decompensates. This brief review focuses on the magnitude of the problem, its detection in the intensive care unit, and recognizes the beneficial effect of prone-positioning on the pulmonary vasculature and right heart.

    Neonates with respiratory distress syndrome (RDS), who are treated according to INSURE protocol; require arterial blood gas (ABG) analysis to decide on appropriate management. We conducted this study to investigate the validity of pulse oximetry instead of frequent ABG analysis in the evaluation of these patients. From a total of 193 blood samples obtained from 30 neonates <1500 grams with RDS, 7.2% were found to have one or more of the followings: acidosis, hypercapnia, or hypoxemia. We found that pulse oximetry in the detection of hyperoxemia had a good validity to appropriately manage patients without blood gas analysis. However, the validity of pulse oximetry was not good enough to detect acidosis, hypercapnia, and hypoxemia. PMID:25999627

    Acute respiratory distress syndrome (ARDS) is defined as the acute onset of noncardiogenic edema and subsequent gas-exchange impairment due to a severe inflammatory process. Recent report on the prognostic value of eicosanoids in patients with ARDS suggests that modulating the inflammatory response through the use of polyunsaturated fatty acids may be a useful strategy for ARDS treatment. The use of enteral diets enriched with eicosapentaenoic acid (EPA) and gamma-linolenic acid (GLA) has reported promising results, showing an improvement in respiratory variables and haemodynamics. However, the interpretation of the studies is limited by their heterogeneity and methodology and the effect of ω-3 fatty acid-enriched lipid emulsion or enteral diets on patients with ARDS remains unclear. Therefore, the routine use of ω-3 fatty acid-enriched nutrition cannot be recommended and further large, homogeneous, and high-quality clinical trials need to be conducted to clarify the effectiveness of ω-3 polyunsaturated fatty acids.

    Early identification of acute respiratory distress syndrome (ARDS) and forceful implementation of standardized therapy algorithms are the mandatory basis of an effective therapy to improve patient outcome. Recently, a new definition of ARDS was implemented, which simplified the diagnostic criteria for ARDS. Evidence-based therapies are rare, but some cornerstone interventions can be recommended. Lung-protective ventilation with high positive end-expiratory pressure and low tidal volume and early prone positioning in severe cases improve survival rate. We here present an integrated "Düsseldorf hands-on translation" in the form of a "one-page" standard operating procedure in order to fasten and standardize both diagnosis and therapeutic algorithms on an intensive care unit.

    We report the successful treatment of two patients with aneurismal subarachnoid hemorrhage complicated by severe respiratory failure and refractory septic shock using simultaneous prone position ventilation and high-volume hemofiltration. These rescue therapies allowed the patients to overcome the critical situation without associated complications and with no detrimental effects on the intracranial and cerebral perfusion pressures. Prone position ventilation is now an accepted therapy for severe acute respiratory distress syndrome, and high-volume hemofiltration is a non-conventional hemodynamic support that has several potential mechanisms for improving septic shock. In this manuscript, we briefly review these therapies and the related evidence. When other conventional treatments are insufficient for providing safe limits of oxygenation and perfusion as part of basic neuroprotective care in subarachnoid hemorrhage patients, these rescue therapies should be considered on a case-by-case basis by an experienced critical care team.

    Acute lung injury and acute respiratory distress syndrome (ARDS) are characterised by severe hypoxemic respiratory failure and poor lung compliance. Despite advances in clinical management, morbidity and mortality remains high. Supportive measures including protective lung ventilation confer a survival advantage in patients with ARDS, but management is otherwise limited by the lack of effective pharmacological therapies. Surfactant dysfunction with quantitative and qualitative abnormalities of both phospholipids and proteins are characteristic of patients with ARDS. Exogenous surfactant replacement in animal models of ARDS and neonatal respiratory distress syndrome shows consistent improvements in gas exchange and survival. However, whilst some adult studies have shown improved oxygenation, no survival benefit has been demonstrated to date. This lack of clinical efficacy may be related to disease heterogeneity (where treatment responders may be obscured by nonresponders), limited understanding of surfactant biology in patients or an absence of therapeutic effect in this population. Crucially, the mechanism of lung injury in neonates is different from that in ARDS: surfactant inhibition by plasma constituents is a typical feature of ARDS, whereas the primary pathology in neonates is the deficiency of surfactant material due to reduced synthesis. Absence of phenotypic characterisation of patients, the lack of an ideal natural surfactant material with adequate surfactant proteins, coupled with uncertainty about optimal timing, dosing and delivery method are some of the limitations of published surfactant replacement clinical trials. Recent advances in stable isotope labelling of surfactant phospholipids coupled with analytical methods using electrospray ionisation mass spectrometry enable highly specific molecular assessment of phospholipid subclasses and synthetic rates that can be utilised for phenotypic characterisation and individualisation of exogenous surfactant

    Interviews with seven of ten known survivors of jumps from the Golden Gate and San Francisco-Oakland Bay bridges showed a unique association between the Golden Gate Bridge and suicide. The study went beyond exploring the nature of suicidal jumps and shed new light on the experience of nearly dying. All the survivors described this experience as tranquil and peaceful. None of them experienced life events or distant memories passing through their minds or before their eyes. However, all of them experienced transcendence and spiritual rebirth phenomena. Suggestions for preventing suicides from the Golden Gate Bridge are discussed, including the construction of a suicide barrier. PMID:1171558

    We report on 17 patients with influenza A H1N1v-associated Adult Respiratory Distress Syndrome who were admitted to the intensive care unit (ICU) between June 11th 2009 and August 10th 2010 (f/m: 8/9; age: median 39 (IQR 29-54) years; SAPS II: 35 (29-48)). Body mass index was 26 (24-35), 24% were overweight and 29% obese. The Charlson Comorbidity Index was 1 (0-2) and all but one patient had comorbid conditions. The median time between onset of the first symptom and admission to the ICU was 5 days (range 0-14). None of the patients had received vaccination against H1N1v. Nine patients received oseltamivir, only two of them within 48 hours of symptom onset. All patients developed severe ARDS (PaO(2)/FiO(2)-Ratio 60 (55-92); lung injury score 3.8 (3.3-4.0)), were mechanically ventilated and on vasopressor support. Fourteen patients received corticosteroids, 7 patients underwent hemofiltration, and 10 patients needed extracorporeal membrane-oxygenation (ECMO; 8 patients veno-venous, 2 patients veno-arterial), three patients Interventional Lung Assist (ILA) and two patients pump driven extracorporeal low-flow CO(2)-elimination (ECCO(2)-R). Seven of 17 patients (41%) died in the ICU (4 patients due to bleeding, 3 patients due to multi-organ failure), while all other patients survived the hospital (59%). ECMO mortality was 50%. The median ICU length-of-stay was 26 (19-44) vs. 21 (17-25) days (survivors vs. nonsurvivors), days on the ventilator were 18 (14-35) vs. 20 (17-24), and ECMO duration was 10 (8-25) vs. 13 (11-16) days, respectively (all p = n.s.). Compared to a control group of 241 adult intensive care unit patients without H1N1v, length of stay in the ICU, rate of mechanical ventilation, days on the ventilator, and TISS 28 scores were significantly higher in patients with H1N1v. The ICU survival tended to be higher in control patients (79 vs. 59%; p = 0.06). Patients with H1N1v admitted to either of our ICUs were young, overproportionally obese and almost all

    PURPOSE The purpose of this study was to compare adolescent and young adult (AYA) pediatric cancer survivors and peers without a history of serious illness on psychological distress, health-related quality of life (HRQOL), health beliefs; examine age at diagnosis and cancer treatment intensity on these outcomes; and examine relationships between number of health problems and the outcomes. PATIENTS AND METHODS AYA cancer survivors (n = 167) and controls (n = 170), recruited during visits to a cancer survivorship clinic and primary care, completed self-report questionnaires of distress, health problems, and health beliefs. For survivors, providers rated treatment intensity and health problems. Results There were no statistically significant differences between survivors and controls in psychological distress or HRQOL. Cancer survivors had less positive health beliefs. Survivors diagnosed as adolescents had significantly greater psychological distress and fewer positive health beliefs than those diagnosed earlier. Survivors with the highest level of treatment intensity had greater anxiety and fewer positive health beliefs than those with less intense treatments. Provider report of current health problems related to survivors' beliefs and mental HRQOL only, whereas patient report of health problems correlated significantly with most psychosocial outcomes and beliefs. CONCLUSION AYA cancer survivors did not differ from peers in psychological adjustment but did endorse less adaptive health beliefs. Survivors diagnosed during adolescence and who had more intensive cancer treatments evidenced poorer psychosocial outcomes. Beliefs about health may be identified and targeted for intervention to improve quality of life, particularly when patient perceptions of current health problems are considered.

    Objective: Respiratory distress syndrome (RDS) is a common cause of respiratory distress in premature infants. This study was designed to evaluate two different RDS treatment protocols by comparing the outcomes. Methods: This study was a double center cross sectional study performed from June to December 2012. During that period, 386 neonates with RDS were hospitalized and treated according to two different therapeutic protocols so-called Acute Care of at-Risk Newborns (ACoRN) respiratory sequence protocol (group I) and Early Nasal Continuous Positive Airway Pressure (E-NCPAP) protocol (group II). The variables and main outcomes of this study were gestational age, birth weight, bronchopulmonary dysplasia (BPD), pulmonary hemorrhage (PH), intraventricular hemorrhage (IVH), air leak and mortality rate (MR). Findings : Out of 386 infants, 202 infants were in group I (male 60.4%, female 39.6%, mean gestational age 316/7 weeks, mean birth weight=1688 grams) and group II included 184 infants (male 61.4%, female 38.6%, mean gestational age 32 weeks, mean birth weight 1787 grams), P= 0.07. The ratios of BPD of group I to group II and PH of group I to group two were not significant (P=0.63 and P=0.84, respectively). Air leak ratio in group I was higher than in group II (P=0.001). Although IVH ratio in group II was higher than in group I (P=0.01), grade III and IV IVH was higher in group I (30% vs. 4.6%). In case of MR, it was higher in group I than in group II (P=0.001). Conclusion: According to the findings the incidence of air leak, grade III and IV IVH and MR was less common in E-NCPAP protocol, so it may show the effectiveness of this protocol. The authors suggest that more researches are needed for more accurate results. PMID:25793046

    The University of Miami School of Medicine asked the Research Triangle Institute for assistance in improvising the negative pressure technique to relieve respiratory distress in infants. Marshall Space Flight Center and Johnson Space Center engineers adapted this idea to the lower-body negative-pressure system seals used during the Skylab missions. Some 20,000 babies succumb to respiratory distress in the U.S. each year, a condition in which lungs progressively lose their ability to oxygenate blood. Both positive and negative pressure techniques have been used - the first to force air into lungs, the second to keep infant's lungs expanded. Negative pressure around chest helps the baby expand his lungs and maintain proper volume of air. If doctors can keep the infant alive for four days, the missing substance in the lungs will usually form in sufficient quantity to permit normal breathing. The Skylab chamber and its leakproof seals were adapted for medical use.

    Mortality of severe acute respiratory distress syndrome (ARDS) remains high. Once conventional mechanical ventilation fails, alternative modes of therapy are used; most of which have limited evidence to support their use. No definitive guidelines exist for the management of these patients with alternate modalities of treatment. We conducted a cross-sectional national survey of 302 adult critical care training programs in the United States to understand the current preferences of intensivists regarding the use of different therapies for severe ARDS, including the use of extracorporeal membrane oxygenation (ECMO). A total of 381 responses were received: 203 critical care faculty and 174 critical care trainees. Airway pressure release ventilation was the initial choice of treatment reported by most when conventional mechanical ventilation strategy failed followed by inhaled nitric oxide and prone positioning. Extracorporeal membrane oxygenation availability was reported by 80% of the respondents at their institutions. Most respondents (83%) would consider ECMO in patients who fail optimal mechanical ventilation strategies, and the majority (60%) believed that ECMO use can facilitate lung protective ventilation, but few favored its use as a first-line modality. The majority of respondents reported limited knowledge of ECMO and desired specific ECMO education during training. PMID:25914957

    Introduction There are some patients with severe respiratory disturbances like adult respiratory distress syndrome (ARDS) and suspicion of brain death, for whom typical performance of the apneic test is difficult to complete because of quick desaturation and rapid deterioration without effective ventilation. To avoid failure of brain death confirmation and possible loss of organ donation another approach to apneic test is needed. We present two cases of patients with clinical symptoms of brain death, with lung pathology (acute lung injury, ARDS, lung embolism and lung infection), in whom apneic tests for recognizing brain death were difficult to perform. During typical performance of apneic test involving the use of oxygen catheter for apneic oxygenation we observed severe desaturation with growing hypotension and hemodynamic destabilization. But with the use of Boussignac CPAP system all necessary tests were successfully completed, confirming the patient’s brain death, which gave us the opportunity to perform procedures for organ donation. The main reason of apneic test difficulties was severe gas exchange disturbances secondary to ARDS. Thus lack of positive end expiratory pressure during classical performance of apneic test leads to quick desaturation and rapid hemodynamic deterioration, limiting the observation period below dedicated at least 10-minute interval. Conclusion The Boussignac CPAP system may be an effective tool for performing transparent apneic test in case of serious respiratory disturbances, especially in the form of acute lung injury or ARDS.

    Background. High mortality and uncertainty about the effectiveness of neuraminidase inhibitors (NAIs) in humans infected with influenza A(H7N9) viruses are public health concerns. Methods. Susceptibility of N9 viruses to NAIs was determined in a fluorescence-based assay. The NAI oseltamivir (5, 20, or 80 mg/kg/day) was administered to BALB/c mice twice daily starting 24, 48, or 72 hours after A/Anhui/1/2013 (H7N9) virus challenge. Results. All 12 avian N9 and 3 human H7N9 influenza viruses tested were susceptible to NAIs. Without prior adaptation, A/Anhui/1/2013 (H7N9) caused lethal infection in mice that was restricted to the respiratory tract and resulted in pulmonary edema and acute lung injury with hyaline membrane formation, leading to decreased oxygenation, all characteristics of human acute respiratory distress syndrome. Oseltamivir at 20 and 80 mg/kg protected 80% and 88% of mice when initiated after 24 hours, and the efficacy decreased to 70% and 60%, respectively, when treatment was delayed by 48 hours. Emergence of oseltamivir-resistant variants was not detected. Conclusions. H7N9 viruses are comparable to currently circulating influenza A viruses in susceptibility to NAIs. Based on these animal studies, early treatment is associated with improved outcomes. PMID:24133191

    Background Lung ultrasound (LUS) is a clinical imaging technique for diagnosing acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). In humans and several large animals, LUS demonstrates similar specificity and sensitivity to computerized tomography (CT) scanning. Current study evaluated the degree of agreement between LUS and CT imaging in characterizing ALI/ARDS in rats. Methods Thirty male Sprague-Dawley rats were imaged by LUS before randomization into three groups to receive intratracheal saline, 3 or 6 mg/kg LPS respectively (n=10). LUS and CT imaging was conducted 2 hours after instillation. Cross table analyses and kappa statistics were used to determine agreement levels between LUS and CT assessments of lung condition. Results Before instillation, rats presented with a largely A-pattern in LUS images, however, a significantly increase B-lines were observed in all groups after instillation and showed dose response to LPS or to saline. One rat treated with 6 mg/kg lipopolysaccharide (LPS) presented with lung consolidation. The agreement between the LUS and the CT in detecting the main characteristics of ALI/ARDS in rat was strong (r=0.758, P<0.01, k=0.737). Conclusions In conclusion, LUS detects ALI/ARDS with high agreement with micro PET/CT scanning in a rat model, suggesting that LUS represents a positive refinement in rat ALI/ARDS disease models.

    The aim of the present research was to investigate the protecting effects of 3,5,4′-tri-O-acetylresveratrol (AC-Rsv) on LPS-induced acute respiratory distress syndrome (ARDS). Lung injuries have been evaluated by histological examination, wet-to-dry weight ratios, and cell count and protein content in bronchoalveolar lavage fluid. Inflammation was assessed by MPO activities and cytokine secretion in lungs and cells. The results showed that AC-Rsv significantly reduced the mortality of mice stimulated with LPS. Pretreatment of AC-Rsv attenuated LPS-induced histological changes, alleviated pulmonary edema, reduced blood vascular leakage, and inhibited the MPO activities in lungs. What was more, AC-Rsv and Rsv treatment reduced the secretion of TNF-α, IL-6, and IL-1β in lungs and NR8383 cells, respectively. Further exploration revealed that AC-Rsv and Rsv treatment relieved LPS-induced inhibition on SIRT1 expression and restrained the activation effects of LPS on MAPKs and NF-κB activation both in vitro and in vivo. More importantly, in vivo results have also demonstrated that the protecting effects of Rsv on LPS-induced inflammation would be neutralized when SIRT1 was in-hibited by EX527. Taken together, these results indicated that AC-Rsv protected lung tissue against LPS-induced ARDS by attenuating inflammation via p38 MAPK/SIRT1 pathway. PMID:26648661

    We compared biologically variable ventilation (V (bv); n = 9) with control mode ventilation (V (c); n = 8) at low tidal volume (VT)--initial 6 ml/kg--in a porcine model of acute respiratory distress syndrome (ARDS). Hemodynamics, respiratory gases, airway pressures, and VT data were measured. Static P-V curves were generated at 5 h. Interleukin (IL)-8 and IL-10 were measured in serum and tracheal aspirate. By 5 h, higher Pa(O(2)) (173 +/- 30 mm Hg versus 119 +/- 23 mm Hg; mean +/- SD; p < 0.0001 group x time interaction [G x T]), lower shunt fraction (6 +/- 1% versus 9 +/- 3%; p = 0.0026, G x T) at lower peak airway pressure (21 +/- 2 versus 24 +/- 1 cm H(2)O; p = 0.0342; G x T) occurred with V (bv). IL-8 concentrations in tracheal aspirate and wet:dry weight ratios were inversely related; p = 0.011. With V (c), IL-8 concentrations were 3.75-fold greater at wet:dry weight ratio of 10. IL-10 concentrations did not differ between groups. In both groups, ventilation was on the linear portion of the P-V curve. With V (bv), VT variability demonstrated an inverse power law indicating fractal behavior. In this model of ARDS, V (bv) improved Pa(O(2)) at lower peak airway pressure and IL-8 levels compared with V (c).

    Typhoid fever is commonly characterized by fever and abdominal pain. Rare complications include intestinal hemorrhage, bowel perforation, delirium, obtundation, and septic shock. Herein we describe the case of a previously healthy 16-year-old male without history of travel, diagnosed with typhoid fever complicated by septic shock and acute respiratory distress syndrome treated with high-dose dexamethasone. This case details severe complications of typhoid fever that are uncommonly seen in developed countries, and the successful response to high-dose dexamethasone as adjunct therapy. High-dose dexamethasone treatment has reportedly decreased Salmonella Typhi mortality, but controlled studies specifically performed in children are lacking, and most reports of its use are over 30 years old and all have originated in developing countries. Providers should include Salmonella Typhi in the differential diagnosis of the pediatric patient with fever, severe abdominal pain, and enteritis, and be aware of its potentially severe complications and the limited data on safety and efficacy of adjunctive therapies that can be considered in addition to antibiotics.

    2013-01-01

    Background Some studies have suggested that the early sustained lung inflation (SLI) procedure is effective in decreasing the need for mechanical ventilation (MV) and improving respiratory outcome in preterm infants. We planned the present randomized controlled trial to confirm or refute these findings. Methods/Design In this study, 276 infants born at 25+0 to 28+6 weeks’ gestation at high risk of respiratory distress syndrome (RDS) will be randomized to receive the SLI maneuver (25 cmH2O for 15 seconds) followed by nasal continuous positive airway pressure (NCPAP) or NCPAP alone in the delivery room. SLI and NCPAP will be delivered using a neonatal mask and a T-piece ventilator. The primary endpoint is the need for MV in the first 72 hours of life. The secondary endpoints include the need and duration of respiratory support (NCPAP, MV and surfactant), and the occurrence of bronchopulmonary dysplasia (BPD).

    Introduction ABCA3 glycoprotein belongs to the ATP-binding cassette (ABC) superfamily of transporters, which utilize the energy derived from hydrolysis of ATP for the translocation of a wide variety of substrates across the plasma membrane. Mutations in the ABCA3 gene are knowingly causative for fatal surfactant deficiency, particularly respiratory distress syndrome (RDS) in term babies. Case Presentation In this study, Sanger sequencing of the whole ABCA3 gene (NCBI NM_001089) was performed in a neonatal boy with severe RDS. A homozygous mutation has been identified in the patient. Parents were heterozygous for the same missense mutation GGA > AGA at position 202 in exon 6 of the ABCA3 gene (c.604G > A; p.G202R). Furthermore, 70 normal individuals have been analyzed for the mentioned change with negative results. Conclusions Regarding Human Genome Mutation Database (HGMD) and other literature recherche, the detected change is a novel mutation and has not been reported before. Bioinformatics mutation predicting tools prefer it as pathogenic. PMID:27437095

    Background: This prospective study was performed to identify whether the early use of nasal continuous positive airway pressure (n CPAP) would reduce the rate of endotracheal intubation, mechanical ventilation and surfactant administration. Materials and Methods: This study was conducted from June 2009 to September 2010 in the Shahid Beheshti University Hospital, Isfahan-Iran. A total of 72 preterm infants with 25-30 weeks gestation who needed respiratory support at 5 min after birth entered the study. Infants were randomly assigned to the very early CPAP (initiated 5 min after birth) or to the late CPAP (initiated 30 min after birth) treatment groups. The primary outcomes were need for intubation and mechanical ventilation during the first 48 h after birth and secondary outcomes were death, pneumothorax, intraventricular hemorrhage, duration of mechanical ventilation and bronchopulmonary dysplasia. Results: There were no significant differences between the two groups with regard to mortality rate, bronchopulmonary dysplasia and patent ductus arteriosus. The need for surfactant administration was significantly reduced in the early CPAP group (P = 0.04). Infants in the early CPAP group less frequently required intubation and mechanical ventilation. Conclusions: Early n CPAP is more effective than late n CPAP for the treatment of respiratory distress syndrome. In addition, the early use of n CPAP would reduce the need for some invasive procedures such as intubation and mechanical ventilation. PMID:23930249

    Pulmonary surfactant (PS) therapy was proven to be highly successful for the treatment of respiratory distress syndrome in premature infants. As a results, early prophylactic (EP) PS therapy has been introduced recently in Europe, the US and Korea. However, no multi-center study was compared EP and late selective (LS) PS therapies in Korea. We performed a retrospective multi-center study to compare the outcomes of EP and LS PS therapies in very preterm infants. We analyzed clinical morbidity and mortality for 1,291 infants in 2010 (LS group) and 1,249 infants in 2011 (EP group); the infants were born <30 weeks of gestation and had birth weight ≤1,250 g, and were chosen from 53 neonatal intensive care units in Korea. Compared to the LS group (22.5%), the overall mortality was better in the EP group (19.9%) and there was no increased need for retreatment.There were additional benefits in the EP group such as fewer associated complications. To the best of knowledge, our study is the first nationwide Korean study to compare the outcomes of EP and LS therapies, and it provides evidences that EP PS therapy is important in very preterm infants to improve for survival and reduce morbidities.

    Objectives: To discuss our center’s experience with acute respiratory distress syndrome (ARDS) secondary to pulmonary tuberculosis (TB) in a major tertiary referral hospital in the Kingdom of Saudi Arabia. Methods: A retrospective review of medical records of all patients with community-acquired pneumonia secondary to mycobacterium TB infection who were admitted for critical care in a single center of King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia from 2004 to 2013. Results: In our review of 350 patients with community-acquired pneumonia admitted to Intensive Care Unit, 11 cases of TB complicated with ARDS were identified. The mean age of patients was 51.9 years. The median time from hospital admission to pulmonary TB diagnosis and start of therapy was 5 days, while the median time from onset of symptoms to initiation of treatment was 18 days. The mortality rate was 64%, and the median length of hospital stay before death was 21.4 days. Delayed treatment, as well as high acute physiology and chronic health evaluation II and CURB-65 scores at presentation, were independent risk factors for death. Conclusion: Patients with pulmonary TB infrequently present to intensive care with acute symptoms that meet all criteria for ARDS. Such a presentation of TB carries a high mortality risk.

    Background: Neonatal respiratory distress syndrome (RDS) in premature infants who survived and its complications are a common problem. Due to high morbidity and mechanical ventilation (MV) nowadays researchers in interested minimizing MV. To determine, in very low birth weight (BW) preterm neonates with RDS, if initial treatment with nasal intermittent mandatory ventilation (early NIMV) compared with early nasal continuous positive airway pressure (early NCPAP) obtains more favorable outcomes in terms of the duration of treatment, and the need for endotracheal tube ventilation. Methods: In this single-center randomized control trial study, infants (BW ≤ 1500 g and/or gestational age ≤ 34 weeks) with respiratory distress were considered eligible. Forty-four infants were randomly assigned to receive early-NIMV and 54 comparable infants to early-NCPAP. Surfactants were given, when FIO2 requirement was of >30%. Primary outcomes were failure of noninvasive respiratory support, that is, the need for MV in the first 48 h of life and for the duration of noninvasive respiratory support in each group. Results: 98 infants were enrolled (44 in the NIMV and 54 in the NCPAP group). The Preventive power of MV of NIMV usage (95.5%) was not lower than the NCPAP (98.1%) strength (hazard ratio: 0.21 (95% confidence interval: 0.02-2.66); P: 0.23). The duration of noninvasive respiratory support in the NIMV group was significantly shorter than NCPAP (the median (range) was 24 (18.00-48.00) h versus 48.00 (22.00-120.00) h in NIMV versus NCPAP groups; P < 0.001). Similarly, the duration of dependency on oxygen was less, for NIMV (the median (range) was 96.00 (41.00-504.00) h versus144.00 (70.00-1130.00) h in NIMV versus NCPAP groups; P: 0.009). Interestingly, time to full enteral feeds and length of hospital stay were more favorable in the NIMV versus the NCPAP group. Conclusions: Initial treatment of RDS with NIMV was safe, and well tolerated. Furthermore, NIMV had excellent

    It is important to assess psychological distress after a diagnosis for cancer survivors, a population with a high risk for psychological distress. The aim of this study is to assess psychological distress among cancer survivors and to clarify the associated factors. In this cross-sectional analysis, data were obtained from standardized questionnaires administered to 1,163 cancer survivors and 49,243 non-cancer survivors who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Survey (2007-2012). We identified the adjusted rates for psychological distress and assessed factors associated with this kind of distress using multivariate logistic regression. Cancer survivors tended to have a higher adjusted rate of psychological distress than the general population. The current depressive symptom rate for cancer survivors was 16.69%, and the adjusted rate for history of depression in cancer survivors was 15.61%. The adjusted rate for higher level of stress was 25.51% in cancer survivors. Among the cancer survivors, younger subjects, female subjects, and those with limited social support were more prone to psychological distress. In addition, current smokers or risky drinkers, those with chronic diseases, and those with a poor self-perception of their health status were also identified as a high-risk group for psychological distress. As the number of cancer survivors has increased, the importance of assessing psychological distress after a cancer diagnosis should be emphasized among all cancer survivors. Further, psychological supportive care interventions for cancer survivors are needed to improve the survival rate and improve their quality of life. PMID:27366010

Cancer survivors tended to have a higher adjusted rate of psychological distress than the general population. The current depressive symptom rate for cancer survivors was 16.69%, and the adjusted rate for history of depression in cancer survivors was 15.61%. The adjusted rate for higher level of stress was 25.51% in cancer survivors. Among the cancer survivors, younger subjects, female subjects, and those with limited social support were more prone to psychological distress. In addition, current smokers or risky drinkers, those with chronic diseases, and those with a poor self-perception of their health status were also identified as a high-risk group for psychological distress. As the number of cancer survivors has increased, the importance of assessing psychological distress after a cancer diagnosis should be emphasized among all cancer survivors. Further, psychological supportive care interventions for cancer survivors are needed to improve the survival rate and improve their quality of life. PMID:27366010

    Terrorism and disasters receive massive media attention, and victims are often approached by reporters. Not much is known about how terror and disaster victims perceive the contact with media and whether such experiences influence mental health. In this study, we describe how positive and negative experiences with media relate to posttraumatic stress (PTS) reactions among survivors of the 2011 Utøya Island terrorist attack in Norway. Face-to-face interviews were conducted with 285 survivors (47.0% female and 53.0% male) 14-15 months after the terrorist attack. Most survivors were approached by reporters (94%), and participated in media interviews (88%). The majority of survivors evaluated their media contact and participation as positive, and media participation was unrelated to PTS reactions. Survivors who found media participation distressing had more PTS reactions (quite distressing: B = 0.440, extremely distressing: B = 0.611, p = .004 in adjusted model). Perceiving media participation as distressing was slightly associated with lower levels of social support (r = -.16, p = .013), and regretting media participation was slightly associated with feeling let down (r = .18, p = .004). Reporters should take care when interviewing victims, and clinicians should be aware of media exposure as a potential additional strain on victims.

    We describe an autopsy case of a patient with pandemic influenza (A/H1N1pdm) virus infection in Japan, who developed rapidly progressive viral pneumonia exhibiting diffuse alveolar damage. A 41-year-old female visited our hospital with a fever of 38.7C. She was a public health nurse with no underlying disease and had had contact with a group of elementary school students who had been infected with the influenza (A/H1N1pdm) virus 1 week earlier. She was prescribed oseltamivir and returned to the hotel where she was staying alone. The next day, she was found dead in her hotel room. At autopsy, both lungs were voluminous and microscopic examination revealed acute-stage, severe diffuse alveolar damage with remarkable mononuclear cell infiltration and hyaline membrane formation in the lungs. CD8-positive T lymphocytes were dominantly observed. Immunohistochemically, influenza A viral protein was confirmed in the damaged type II pneumocytes and also in the infiltrated macrophages. Real-time RT-PCR analysis of both pre- and post-mortem pharyngeal swabs confirmed a novel influenza (A/H1N1pdm) virus infection. This is the second autopsy case of influenza (A/H1N1pdm) virus infection in Japan, and the findings indicated that the patient died due to an exceptionally rapid progression of viral pneumonia. This case indicates that patients with influenza (A/H1N1pdm) virus infection should be carefully monitor for acute respiratory distress syndrome. PMID:20093769

    Endothelial cell (EC) dysfunction is a critical mediator of the acute respiratory distress syndrome (ARDS). Recent studies have demonstrated that stromal cell–derived factor 1α (SDF-1α) promotes EC barrier integrity. Our previous studies used a SDF-1α analogue CTCE-0214 (CTCE) in experimental sepsis and demonstrated that it attenuated vascular leak and modulated microRNA (miR) levels. We examined the hypothesis that CTCE improves EC function in lipopolysaccharide (LPS)-induced ARDS through increasing miR-126 expression. Human microvascular endothelial cells (HMVECs) were treated with thrombin to disrupt the EC integrity followed by incubation with CTCE or SDF-1α. Barrier function was determined by trans-endothelial electrical resistance assay. CTCE-induced alterations in miRNA expression and signaling pathways involved in barrier function were determined. Thrombin-induced vascular leak was abrogated by both CTCE and SDF-1α. CTCE also prevented thrombin-induced decreases of vascular endothelial (VE)-cadherin cell surface expression and expansion of the intercellular space. CTCE increased miR-126 levels and induced activation of AKT/Rac 1 signaling. Cotreatment with a miR-126 inhibitor blocked the protective effects of CTCE on AKT activation and endothelial permeability. In subsequent in vivo studies, ARDS was induced by intratracheal instillation of LPS. Intravenous injection of CTCE diminished the injury severity as evidenced by significant reductions in protein, immune cells, inflammatory cytokines and chemokines in the bronchoalveolar lavage fluid, increased miR-126 expression and decreased pulmonary vascular leak and alveolar edema. Taken together, our data show that CTCE improves endothelial barrier integrity through increased expression of miR-126 and activation of Rac 1 signaling and represents an important potential therapeutic strategy in ARDS.

    There is an unmet need for noninvasive, specific and quantitative imaging of inherent inflammatory activity. Vascular adhesion protein-1 (VAP-1) translocates to the luminal surface of endothelial cells upon inflammatory challenge. We hypothesized that in a porcine model of acute respiratory distress syndrome (ARDS), positron emission tomography (PET) with sialic acid-binding immunoglobulin-like lectin 9 (Siglec-9) based imaging agent targeting VAP-1 would allow quantification of regional pulmonary inflammation. ARDS was induced by lung lavages and injurious mechanical ventilation. Hemodynamics, respiratory system compliance (Crs) and blood gases were monitored. Dynamic examination using [15O]water PET-CT (10 min) was followed by dynamic (90 min) and whole-body examination using VAP-1 targeting 68Ga-labeled 1,4,7,10-tetraaza cyclododecane-1,4,7-tris-acetic acid-10-ethylene glycol-conjugated Siglec-9 motif peptide ([68Ga]Ga-DOTA-Siglec-9). The animals received an anti-VAP-1 antibody for post-mortem immunohistochemistry assay of VAP-1 receptors. Tissue samples were collected post-mortem for the radioactivity uptake, histology and immunohistochemistry assessment. Marked reduction of oxygenation and Crs, and higher degree of inflammation were observed in ARDS animals. [68Ga]Ga-DOTA-Siglec-9 PET showed significant uptake in lungs, kidneys and urinary bladder. Normalization of the net uptake rate (Ki) for the tissue perfusion resulted in 4-fold higher uptake rate of [68Ga]Ga-DOTA-Siglec-9 in the ARDS lungs. Immunohistochemistry showed positive VAP-1 signal in the injured lungs. Detection of pulmonary inflammation associated with a porcine model of ARDS was possible with [68Ga]Ga-DOTA-Siglec-9 PET when using kinetic modeling and normalization for tissue perfusion.

    2014-01-01

    Objective To compare quantitative computed tomography (CT) analysis and single-indicator thermodilution to measure pulmonary edema in patients with acute respiratory distress syndrome (ARDS). Method Ten patients with ARDS were included. All underwent spiral CT of the thorax for estimating gas content of lung (GVCT), tissue volume of lung (TVCT), tissue volume index (TVI), mean radiographic attenuation (CTmean) for the whole lung and gas-to-tissue ratio (g/t). Pulmonary thermal volume (PTV) and extravascular lung water index (ELWI) were determined by the PiCCO plus system. CT or single-indicator thermodilution variables were correlated with respiratory system compliance (Crs), PaO2/FiO2, and Acute Physiology And Chronic Health EvaluationII (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores. Results 1) TVCT and PTV were positively correlated (r =0.8878; P = 0.0006; equation of regression line: PTV = 1.0793 × TVCT + 179.8) as were TVI and ELWI (r =0.9459; P < 0.0001; equation of regression line: ELWI = 1.4506 × TVI-8.7792). The bias between TVCT and PTV as well as TVI and ELWI was -277 ± 217 and 0.62 ± 4.56, respectively. 2) ELWI and CT distribution of lung-tissue compartments were not correlated. 3) CT or single-indicator thermodilution variables were not correlated with Crs, PaO2/FiO2 or APACHE II or SOFA score. Conclusion Quantitative CT analysis and single-indicator thermodilution showed good agreement in measuring pulmonary edema. PMID:24625023

    A randomised trial was conducted in 82 centres using the porcine surfactant extract, Curosurf, to compare two regimens of multiple doses to treat infants with respiratory distress syndrome and arterial to alveolar oxygen tension ratio < 0.22. Infants were randomly allocated to a low dosage group (100 mg/kg initially, with two further doses at 12 and 24 hours to a maximum cumulative total of 300 mg/kg; n = 1069) or a high dosage group (200 mg/kg initially with up to four further doses of 100 mg/kg to a maximum cumulative total of 600 mg/kg; n = 1099). There was no difference between those allocated low and high dosage in the rates of death or oxygen dependency at 28 days (51.1% v 50.8%; difference -0.3%, 95% confidence interval (CI) -4.6% to 3.9%), death before discharge (25.0% v 23.5%; difference -1.5%, 95% CI -5.1% to 2.2%), and death or oxygen dependency at the expected date of delivery (32.2% v 31.0%; difference -1.2%, 95% CI -5.2% to 2.7%). For 14 predefined secondary measures of clinical outcome there were no significant differences between the groups but the comparison of duration of supplemental oxygen > 40% did attain significance; 48.4% of babies in the low dose group needed > 40% oxygen after three days compared with 42.6% of those in the high dose group. The total amount of surfactant administered in the low dose regimen (mean 242 mg phospholipid/kg) was probably enough to replace the entire pulmonary surfactant pool. Adopting the low dose regimen would lead to considerable cost savings, with no clinically significant loss in efficacy. PMID:8215564

    Introduction: Nowadays particular emphasis is placed on the developmental aspects of premature infants care. Massage therapy is one of the best-known methods of caring. Due to the minimal touch policy in neonatal intensive care units (NICUs), massaging is not usually performed on premature infants. However, there is not sufficient evidence to support the claim that newborn infants with complex medical conditions should not be massaged. This study aimed to determine the effects of massage with coconut and sunflower oils on oxygen saturation of infants with respiratory distress syndrome (RDS) treated with nasal continuous positive airway pressure (NCPAP). Methods: This was a randomized controlled trial on 90 newborns who were admitted to Alzahra Hospital (Tabriz, Iran). The infants were divided into control and massage therapy groups (massage with coconut and sunflower oils). Data was collected using a hospital documentation form. A 15-minute daily massage was performed for 3 days. Respiratory rate (RR), fraction of inspired oxygen (FiO2) and oxygen saturation were measured 5 minutes before the massage, 3 times during the massage, and 5 minutes after the massage. The collected data was analyzed using a mixed model. Results: In comparison to coconut oil and control groups, mean oxygen saturation of sunflower oil group was improved. In addition, the coconut massage group showed lower oxygen saturation than the control group but was all values were within the normal range. Although massage decreased oxygen saturation, there was no need to increase FiO2. Conclusion: Massage therapy can provide developmental care for infants treated with NCPAP. PMID:25276695

    This study was conducted to investigate the effect of intratracheal and intravenous administration of microparticles (MPs) on developing acute respiratory distress syndrome (ARDS). The blood MPs from lipopolysaccharide-treated rats were collected and examined by transmission electron microscopy (TEM). Cellular source of the MPs was identified by fluorescent-labeled antibodies after the circulating MPs were delivered to naïve rats. Levels of myeloperoxidase (MPO), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-10 productions in bronchoalveolar lavage fluid (BALF) and plasma were determined 24 h after the rats received intratracheal and intravenous administration of the MPs. Histopathologic examination of lungs was performed by light microscope. A TEM image of MPs showed spherical particles at a variable diameter from 0.1 to 0.5 µm. Endothelial- and leukocyte-derived vesicles were abundant in the investigated samples. Treatment with MPs may lead to significant increases in MPO, TNF-α, IL-1β, and IL-10 productions in BALF and plasma of the rats (all P < 0.001). Morphological observation indicated that alveolar structures were destroyed with a large amount of neutrophil infiltration in the lungs of the MP-treated rats. Perivascular and/or intra-alveolar hemorrhage were serious and hyaline membrane formed in the alveoli. Intratracheal and intravenous approaches to delivery of the circulating MPs to naïve recipient rats may induce ARDS. This presents an inducer of the onset of ARDS and provides potential therapeutic targets for attenuating lung injury. PMID:26088862

    Background: Surfactant administration together with nasal Continuous Positive Airway Pressure (nCPAP) administration is considered to be the basis for Newborn's Respiratory Distress Syndrome (RDS) management. This study evaluated the method of directing the surfactant to the lungs in newborns affiliated with RDS through i-gel (i-gel surfactant administration/i-gelSA) compared to the standard care INSURE method, in a clinical trial. Materials and Methods: This randomized control trial (RCT) was done on newborns weighing ≥2000 g, with RDS, while being supported with Bubble-CPAP. Newborns, which required FiO2 ≥0.3 under Continuous Distending Pressure (CDP) ≥5 cm H2O for more than 30 minutes to maintain SpO2 in the range of 89 - 95%, were given 100 mg/kg of Survanta. In the interventional group or the i-gelSA (i-gel Surfactant Administration) group, 35 newborns experienced surfactant administration with i-gel and 35 newborns in the control or INSURE group. The average a/APO2 before and after surfactant administration, repeated need for surfactant administration, average nCPAP duration, need for invasive mechanical ventilation, pneumothorax, and the average duration of hospitalization in the Neonatal Intensive Care Unit (NICU) were compared. Results: Although the average a/APO2 showed no significant difference before the procedure; in the i-gelSA group, this average was meaningfully higher after the administration of the surfactant (P = 0.001). The other factors showed no significant difference. Conclusion: According to the results of this study, the surfactant administration using i-gel was more successful in oxygenation improvement than the INSURE method, and the i-gel method could even be promoted to the standard care position. However, more research is needed in this area. PMID:25221763

    Background: Various strategies have been suggested for the treatment of respiratory distress syndrome (RDS). Objectives: The aim of this study was to compare the efficacies of two common methods of RDS management among neonates with low birth weight. Patients and Methods: A cohort study was conducted on 98 neonates with definite diagnosis of RDS during 2008-2009. The neonates were divided into two groups by a blinded supervisor using simple randomization (odd and even numbers). Forty-five cases in the first group were treated with intubation, surfactant therapy, extubation (INSURE method) followed by nasal continuous positive airway pressure (N.CPAP) and 53 cases in the second group underwent intubation, surfactant therapy followed by mechanical ventilation (MV). Results: Five (11.1%) cases in the first group and 23 (43%) cases in the second group expired during the study. The rates of MV dependency among cases with INSURE failure and cases in the MV group were 37% and 83%, respectively (P < 0.001). Birth weight (BW) (P = 0.017), presence of retinopathy of prematurity (P = 0.022), C/S delivery (P = 0.029) and presence of lung bleeding (P = 0.010) could significantly predict mortality in the second group, although only BW (P = 0.029) had a significant impact on the mortality rate in the first group. Moreover, BW was significantly related to the success rate in the first group (P = 0.001). Conclusions: Our findings demonstrated that INSURE plus NCPAP was more effective than the routine method (permanent intubation after surfactant prescription). In addition, the lower rates of mortality, MV dependency, duration of hospitalization, and complications were observed in cases treated with the INSURE method compared to the routine one.

    Summary Background In a previous randomised controlled phase 2 trial, intravenous infusion of salbutamol for up to 7 days in patients with acute respiratory distress syndrome (ARDS) reduced extravascular lung water and plateau airway pressure. We assessed the effects of this intervention on mortality in patients with ARDS. Methods We did a multicentre, placebo-controlled, parallel-group, randomised trial at 46 UK intensive-care units between December, 2006, and March, 2010. Intubated and mechanically ventilated patients (aged ≥16 years) within 72 h of ARDS onset were randomly assigned to receive either salbutamol (15 μg/kg ideal bodyweight per h) or placebo for up to 7 days. Randomisation was done by a central telephone or web-based randomisation service with minmisation by centre, pressure of arterial oxygen to fractional inspired oxygen concentration (PaO2/FIO2) ratio, and age. All participants, caregivers, and investigators were masked to group allocation. The primary outcome was death within 28 days of randomisation. Analysis was by intention-to-treat. This trial is registered, ISRCTN38366450 and EudraCT number 2006-002647-86. Findings We randomly assigned 162 patients to the salbutamol group and 164 to the placebo group. One patient in each group withdrew consent. Recruitment was stopped after the second interim analysis because of safety concerns. Salbutamol increased 28-day mortality (55 [34%] of 161 patients died in the salbutamol group vs 38 (23%) of 163 in the placebo group; risk ratio [RR] 1·47, 95% CI 1·03–2·08). Interpretation Treatment with intravenous salbutamol early in the course of ARDS was poorly tolerated. Treatment is unlikely to be beneficial, and could worsen outcomes. Routine use of β-2 agonist treatment in ventilated patients with this disorder cannot be recommended. Funding UK Medical Research Council, UK Department of Health, UK Intensive Care Foundation.

    This study seeks to evaluate the potential benefits of high doses of ambroxol treatment for acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) by conducting a meta-analysis based on randomized controlled trials (RCTs). We searched the Pubmed, Embase, China National Knowledge Infrastructure, and Wanfang databases through December 2013. Only RCTs evaluating high doses of ambroxol (≥15 mg/kg or 1000 mg/day) treatment for patients with ALI/ARDS were selected. We included 10 RCTs involving 508 patients. Adjuvant treatment with high doses of ambroxol increased PaO(2)/FiO(2) (weight mean differences [WMD] = 69.18, 95% confidence intervals [CI]: 41.71-96.65), PO(2) (WMD = 11.74, 95% CI: 8.50-14.99), and SaO(2) (WMD = 2.15, 95% CI: 1.60-2.71) compared with usual treatment. Treatment with high doses of ambroxol appeared to reduce serum tumor necrosis factor-α level (WMD -7.92 µg/L; 95% CI, -10.94 to -4.9) and interleukin-6 level (WMD = -20.65 µg/L, 95% CI: -24.74 to -16.55) and to increase serum superoxide dismutase level (WMD = 19.07 NU/mL, 95% CI: 6.16-31.97). The findings suggest that treatment with high doses of ambroxol appears to improve PaO(2)/FiO(2), PO(2), and SaO(2), and the benefits might be related to ambroxol's anti-oxidant and anti-inflammatory properties.

    Background The main soluble form of the receptor for advanced glycation end-products (sRAGE) is elevated during acute respiratory distress syndrome (ARDS). However other RAGE isoforms and multiple ligands have been poorly reported in the clinical setting, and their respective contribution to RAGE activation during ARDS remains unclear. Our goal was therefore to describe main RAGE isoforms and ligands levels during ARDS. Methods 30 ARDS patients and 30 mechanically ventilated controls were prospectively included in this monocenter observational study. Arterial, superior vena cava and alveolar fluid levels of sRAGE, endogenous-secretory RAGE (esRAGE), high mobility group box-1 protein (HMGB1), S100A12 and advanced glycation end-products (AGEs) were measured in duplicate ELISA on day 0, day 3 and day 6. In patients with ARDS, baseline lung morphology was assessed with computed tomography. Results ARDS patients had higher arterial, central venous and alveolar levels of sRAGE, HMGB1 and S100A12, but lower levels of esRAGE and AGEs, than controls. Baseline arterial sRAGE, HMGB1 and S100A12 were correlated with nonfocal ARDS (AUC 0.79, 0.65 and 0.63, respectively). Baseline arterial sRAGE, esRAGE, S100A12 and AGEs were associated with severity as assessed by PaO2/FiO2. Conclusions This is the first kinetics study of levels of RAGE main isoforms and ligands during ARDS. Elevated sRAGE, HMGB1 and S100A12, with decreased esRAGE and AGEs, were found to distinguish patients with ARDS from those without. Our findings should prompt future studies aimed at elucidating RAGE/HMGB1/S100A12 axis involvement in ARDS. Trial Registration clinicaltrials.gov Identifier: NCT01270295. PMID:26274928

Treatment with high doses of ambroxol appeared to reduce serum tumor necrosis factor-α level (WMD -7.92 µg/L; 95% CI, -10.94 to -4.9) and interleukin-6 level (WMD = -20.65 µg/L, 95% CI: -24.74 to -16.55) and to increase serum superoxide dismutase level (WMD = 19.07 NU/mL, 95% CI: 6.16-31.97). The findings suggest that treatment with high doses of ambroxol appears to improve PaO(2)/FiO(2), PO(2), and SaO(2), and the benefits might be related to ambroxol's anti-oxidant and anti-inflammatory properties.

    In patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), a recent ARDS Network randomized controlled trial demonstrated that a low tidal volume (VT) mechanical ventilation strategy (6 ml/kg) reduced mortality by 22% compared with traditional mechanical ventilation (12 ml/kg). In this study, we examined the relative efficacy of low VT mechanical ventilation among 902 patients with different clinical risk factors for ALI/ARDS who participated in ARDS Network randomized controlled trials. The clinical risk factor for ALI/ARDS was associated with substantial variation in mortality. The risk of death (before discharge home with unassisted breathing) was highest in patients with sepsis (43%); intermediate in subjects with pneumonia (36%), aspiration (37%), and other risk factors (35%); and lowest in those with trauma (11%) (p < 0.0001). Despite these differences in mortality, there was no evidence that the efficacy of the low VT strategy varied by clinical risk factor (p = 0.76, for interaction between ventilator group and risk factor). There was also no evidence of differential efficacy of low VT ventilation in the other study outcomes: proportion of patients achieving unassisted breathing (p = 0.59), ventilator-free days (p = 0.58), or development of nonpulmonary organ failure (p = 0.44). Controlling for demographic and clinical covariates did not appreciably affect these results. After reclassifying the clinical risk factors as pulmonary versus nonpulmonary predisposing conditions and infection-related versus non-infection-related conditions, there was still no evidence that the efficacy of low VT ventilation differed among clinical risk factor subgroups. In conclusion, we found no evidence that the efficacy of the low VT ventilation strategy differed among clinical risk factor subgroups for ALI/ARDS.

    Aim: Mechanical ventilation is an invasive method and causes to important problems in the respiratory tract and lung parenchyma. The objective of our study was to investigate if administration of early surfactant and nasal continuous positive airway pressure (nCPAP) was superior to delayed surfactant administration and mechanical ventilation. Material and Methods: The study was conducted in the Van 100th Year University, Medical Faculty Hospital, Neonatal Intensive Care Unit. One hundred and nine infants with respiratory distrss syndrome (RDS) with a gestational age of 32 weeks and/or below were included in the study. Surfactant was given to 61 infants in the delivery room or intensive care unit and subsequently nCPAP was administered. Surfactant was administered in 48 infants in the control group and mechanical ventilation was inititated subsequently. Informed consent was obtained from the relatives of all patients and ethics committee approval was also obtained (Approval number: 03.02.2011/15). Results: There was no statistically significant difference between the two groups in terms of gestational age, birth weight, gender, height and head circumference measurements (p>0.05). The mean hospitalization time in the patients in the study group was 24.4±17.8 days, whereas the mean time of nCPAP was 28.4 (4–120) hours. In the study group, intracranial hemorrhage was found with a rate of 27.85%, bronchopulmonary dysplasia was found with a rate of 4.91%, pneumothorax was found with a rate of 3.27%, necrotizing enterocolitis was found with a rate of 3.27%, patent ductus arteriosus was found with a rate of 16.39, sepsis was found with a rate of 22.95% and retinopathy of prematurity was found with a rate of 1.63%. No statistically significant difference was found between the study and control groups in terms of the rates of complications. During the follow-up period, 17 (27.86%) patients were lost. The length of stay on mechanical ventilation in the study group was

    This research aims to examine whether there are differences in the level of anxiety, the perception of danger, the reliance on security forces and signs of psychological distress during times of war between two groups of Holocaust survivors: Jews of Greece and Jews of Eastern and Western Europe, while assessing their psychological ability to cope with the wave of terrorism against the Israeli population. The Jews of Greece have been portrayed as being different, both by the Nazis and by Jews from other countries, as well as by the Greeks themselves. Their strength of spirit, encouraging them to rebel and resist, as well as their physical strength, were renowned in the concentration camps. Each of these traits has been supported by specific documentation in history books dealing with the Jews of Greece during the Holocaust. Fifty-eight years after the Holocaust and before it disappears from historical record, we scientifically examined the psychological or mental capacity of these people to withstand the wave of terrorism. The study included 33 European Jewish Holocaust survivors and 38 Greek Jewish Holocaust survivors. The subjects completed four questionnaires. The main results are: 1. The average level of anxiety among Greek Holocaust survivors is clearly lower than that of other Holocaust survivors--an average of 10.00 compared to 16.48 (t = 4.83, p < 0.001). 2. The average level of psychological distress during times of war among Greek Holocaust survivors is 2.10 compared to 2.65 among other Holocaust survivors (t = 4.24, p < 0.001). 3. The average level of trust in the security forces among Greek Holocaust survivors is 3.67 compared to 2.70 among the other Holocaust survivors (t = 4.354, p < 0.001). 4. The average level of perception of danger among Greek Holocaust survivors is 2.75 compared to 3.39 among other Holocaust survivors (t = 2.60, p < 0.01). 5. The readiness to emigrate from Israel is 1.02 among Greek Holocaust survivors compared to 2.09 among other

    A 30-year-old woman with malnutrition due to alcoholism and eating disorders was found to have acute respiratory distress syndrome (ARDS) and sepsis due to severe Streptococcus pneumoniae pneumonia. S. pneumoniae was detected by an in vitro rapid immunochromatographic assay for S. pneumoniae antigen in urine on the day of admission and by blood culture 2 days after admission. Symptoms and laboratory findings improved after treatment with sivelestat sodium hydrate, antibiotics, and mechanical ventilation. Treatment with sivelestat sodium hydrate also decreased serum neutrophil elastase activity. This case demonstrates the usefulness of early treatment with sivelestat sodium hydrate in ARDS due to severe pneumonia.

    Background: The aim of this prospective study was to assess whether the presence of septic shock could influence the dose response to inhaled nitric oxide (NO) in NO-responding patients with adult respiratory distress syndrome (ARDS). Results: Eight patients with ARDS and without septic shock (PaO2 = 95 ± 16 mmHg, PEEP = 0, FiO2 = 1.0), and eight patients with ARDS and septic shock (PaO2 = 88 ± 11 mmHg, PEEP = 0, FiO2 = 1.0) receiving exclusively norepinephrine were studied. All responded to 15 ppm inhaled NO with an increase in PaO2 of at least 40 mmHg, at FiO2 1.0 and PEEP 10 cmH2O. Inspiratory intratracheal NO concentrations were recorded continuously using a fast response time chemiluminescence apparatus. Seven inspiratory NO concentrations were randomly administered: 0.15, 0.45, 1.5, 4.5, 15, 45 and 150 ppm. In both groups, NO induced a dose-dependent decrease in mean pulmonary artery pressure (MPAP), pulmonary vascular resistance index (PVRI), and venous admixture (QVA/QT), and a dose-dependent increase in PaO2/FiO2 (P ≤ 0.012). Dose-response of MPAP and PVRI were similar in both groups with a plateau effect at 4.5 ppm. Dose-response of PaO2/FiO2 was influenced by the presence of septic shock. No plateau effect was observed in patients with septic shock and PaO2/FiO2 increased by 173 ± 37% at 150 ppm. In patients without septic shock, an 82 ± 26% increase in PaO2/FiO2 was observed with a plateau effect obtained at 15 ppm. In both groups, dose-response curves demonstrated a marked interindividual variability and in five patients pulmonary vascular effect and improvement in arterial oxygenation were dissociated. Conclusion: For similar NOinduced decreases in MPAP and PVRI in both groups, the increase in arterial oxygenation was more marked in patients with septic shock. PMID:11056694

    Surfactant replacement therapy (SRT) has been shown to reduce mortality and air leaks in preterm neonates from high-income countries (HICs). The safety and efficacy of SRT in low- and middle- income countries (LMICs) have not been systematically evaluated. The major objectives of this review were to assess the (1) efficacy and safety, and (2) feasibility and cost effectiveness of SRT in LMIC settings. We searched the following databases—MEDLINE, CENTRAL, CINAHL, EMBASE and WHOLIS using the search terms 'surfactant' OR 'pulmonary surfactant'. Both experimental and observational studies that enrolled preterm neonates with or at-risk of respiratory distress syndrome (RDS) and required surfactant (animal-derived or synthetic) were included. A total of 38 relevant studies were found; almost all were from level-3 neonatal units. Pooled analysis of two randomized controlled trials (RCTs) and 22 observational studies showed a significant reduction in mortality at the last available time point in neonates who received SRT (relative risk (RR) 0.67; 95% confidence interval (CI) 0.57 to 0.79). There was also a significant reduction in the risk of air leaks (five studies; RR 0.51; 0.29 to 0.90). One RCT and twelve observational studies reported the risk of bronchopulmonary dysplasia (BPD) with contrasting results; while the RCT and most before-after/cohort studies showed a significant reduction or no effect, the majority of the case-control studies demonstrated significantly higher odds of receiving SRT in neonates who developed BPD. Two studies—one RCT and one observational—found no difference in the proportion of neonates developing pulmonary hemorrhage, while another observational study reported a higher incidence in those receiving SRT. The failure rate of the intubate-surfactant-extubate (InSurE) technique requiring mechanical ventilation or referral varied from 34 to 45% in four case-series. No study reported on the cost effectiveness of SRT. Available evidence

    Background: An acute respiratory distress syndrome (ARDS) is still one of the major challenges in critically ill patients. This study aimed to investigate the effect of inhibiting c-Jun N-terminal kinase (JNK) on ARDS in a lipopolysaccharide (LPS)-induced ARDS rat model. Methods: Thirty-six rats were randomized into three groups: control, LPS, and LPS + JNK inhibitor. Rats were sacrificed 8 h after LPS treatment. The lung edema was observed by measuring the wet-to-dry weight (W/D) ratio of the lung. The severity of pulmonary inflammation was observed by measuring myeloperoxidase (MPO) activity of lung tissue. Moreover, the neutrophils in bronchoalveolar lavage fluid (BALF) were counted to observe the airway inflammation. In addition, lung collagen accumulation was quantified by Sircol Collagen Assay. At the same time, the pulmonary histologic examination was performed, and lung injury score was achieved in all three groups. Results: MPO activity in lung tissue was found increased in rats treated with LPS comparing with that in control (1.26 ± 0.15 U in LPS vs. 0.77 ± 0.27 U in control, P < 0.05). Inhibiting JNK attenuated LPS-induced MPO activity upregulation (0.52 ± 0.12 U in LPS + JNK inhibitor vs. 1.26 ± 0.15 U in LPS, P < 0.05). Neutrophils in BALF were also found to be increased with LPS treatment, and inhibiting JNK attenuated LPS-induced neutrophils increase in BALF (255.0 ± 164.4 in LPS vs. 53 (44.5-103) in control vs. 127.0 ± 44.3 in LPS + JNK inhibitor, P < 0.05). At the same time, the lung injury score showed a reduction in LPS + JNK inhibitor group comparing with that in LPS group (13.42 ± 4.82 vs. 7.00 ± 1.83, P = 0.001). However, the lung W/D ratio and the collagen in BALF did not show any differences between LPS and LPS + JNK inhibitor group. Conclusions: Inhibiting JNK alleviated LPS-induced acute lung inflammation and had no effects on pulmonary edema and fibrosis. JNK inhibitor might be a potential therapeutic medication in ARDS, in the

    IMPORTANCE Noninvasive ventilation (NIV) with a face mask is relatively ineffective at preventing endotracheal intubation in patients with acute respiratory distress syndrome (ARDS). Delivery of NIV with a helmet may be a superior strategy for these patients. OBJECTIVE To determine whether NIV delivered by helmet improves intubation rate among patients with ARDS. DESIGN, SETTING, AND PARTICIPANTS Single-center randomized clinical trial of 83 patients with ARDS requiring NIV delivered by face mask for at least 8 hours while in the medical intensive care unit at the University of Chicago between October 3, 2012, through September 21, 2015. INTERVENTIONS Patients were randomly assigned to continue face mask NIV or switch to a helmet for NIV support for a planned enrollment of 206 patients (103 patients per group). The helmet is a transparent hood that covers the entire head of the patient and has a rubber collar neck seal. Early trial termination resulted in 44 patients randomized to the helmet group and 39 to the face mask group. MAIN OUTCOMES AND MEASURES The primary outcome was the proportion of patients who required endotracheal intubation. Secondary outcomes included 28-day invasive ventilator–free days (ie, days alive without mechanical ventilation), duration of ICU and hospital length of stay, and hospital and 90-day mortality. RESULTS Eighty-three patients (45% women; median age, 59 years; median Acute Physiology and Chronic Health Evaluation [APACHE] II score, 26) were included in the analysis after the trial was stopped early based on predefined criteria for efficacy. The intubation rate was 61.5% (n = 24) for the face mask group and 18.2% (n = 8) for the helmet group (absolute difference, −43.3%; 95% CI, −62.4%to −24.3%; P < .001). The number of ventilator-free days was significantly higher in the helmet group (28 vs 12.5, P < .001). At 90 days, 15 patients (34.1%) in the helmet group died compared with 22 patients (56.4%) in the face mask group

    Objectives A recent update of the definition of acute respiratory distress syndrome (ARDS) proposed an empirical classification based on ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) at ARDS onset. Since the proposal did not mandate PaO2/FiO2 calculation under standardised ventilator settings (SVS), we hypothesised that a stratification based on baseline PaO2/FiO2 would not provide accurate assessment of lung injury severity. Design A prospective, multicentre, observational study. Setting A network of teaching hospitals. Participants 478 patients with eligible criteria for moderate (100300). Primary and secondary outcomes Group severity and hospital mortality. Results At ARDS onset, 173 patients had a PaO2/FiO2≤100 but only 38.7% met criteria for severe ARDS at 24 h under SVS. When assessed under SVS, 61.3% of patients with severe ARDS were reclassified as moderate, mild and non-ARDS, while lung severity and hospital mortality changed markedly with every PaO2/FiO2 category (p<0.000001). Our model of risk stratification outperformed the stratification using baseline PaO2/FiO2 and non-standardised PaO2/FiO2 at 24 h, when analysed by the predictive receiver operating characteristic (ROC) curve: area under the ROC curve for stratification at baseline was 0.583 (95% CI 0.525 to 0.636), 0.605 (95% CI 0.552 to 0.658) at 24 h without SVS and 0.693 (95% CI 0.645 to 0.742) at 24 h under SVS (p<0.000001). Conclusions Our findings support the need for patient assessment under SVS at 24 h after ARDS onset to assess disease severity, and have implications for the

    The initial hypoxemic level of acute respiratory distress syndrome (ARDS) defined according to Berlin definition might not be the optimal predictor for prognosis. We aimed to determine the predictive validity of the stabilized ratio of partial pressure arterial oxygen and fraction of inspired oxygen (PaO2/FiO2 ratio) following standard ventilator setting in the prognosis of patients with ARDS.This prospective observational study was conducted in a single tertiary medical center in Taiwan and compared the stabilized PaO2/FiO2 ratio (Day 1) following standard ventilator settings and the PaO2/FiO2 ratio on the day patients met ARDS Berlin criteria (Day 0). Patients admitted to intensive care units and in accordance with the Berlin criteria for ARDS were collected between December 1, 2012 and May 31, 2015. Main outcome was 28-day mortality. Arterial blood gas and ventilator setting on Days 0 and 1 were obtained.A total of 238 patients met the Berlin criteria for ARDS were enrolled, and they were classified as mild (n = 50), moderate (n = 125), and severe (n = 63) ARDS, respectively. Twelve (5%) patients who originally were classified as ARDS did not continually meet the Berlin definition, and a total of 134 (56%) patients had the changes regarding the severity of ARDS from Day 0 to Day 1. The 28-day mortality rate was 49.1%, and multivariate analysis identified age, PaO2/FiO2 on Day 1, number of organ failures, and positive fluid balance within 5 days as significant risk factors of death. Moreover, the area under receiver-operating curve for mortality prediction using PaO2/FiO2 on Day 1 was significant higher than that on Day 0 (P = 0.016).PaO2/FiO2 ratio on Day 1 after applying mechanical ventilator is a better predictor of outcomes in patients with ARDS than those on Day 0.

    This study evaluates the effects of two group interventions, the Bereavement Group Postvention (BGP) and the Social Group Postvention (SGP), on the bereavement outcomes in widowed survivors of suicide. The goals were to determine if the group interventions would significantly decrease levels of depression, psychological distress, and grief, as well as significantly increase the level of social adjustment among widowed survivors of suicide. Sixty widowed survivors of suicide were randomized to either the BGP or SGP intervention for 1-1/2 hour weekly sessions over an 8-week period. Study participants were recruited through various media and community referrals and initiated telephone contact with the study investigators. Statistically significant changes were found on all measures when the SGP and the BGP were combined for analyses on posttreatment assessments at 3 to 5 days after completion of the group intervention, and 6 months and 12 months after the intervention. Participants experienced a significant reduction in overall depression, psychological distress, and grief, as well as an increase in social adjustment. Further research with tighter controls of confounding variables as well as the inclusion of a no-treatment control group is indicated. PMID:11775718

    We examined the distress level of 102 Holocaust survivors in Israel during a recent period of continuous exposure of the Israeli population to terror and the threat of missile attack. Based on the Conservation of Resources (COR) theory, we explored the contribution of losses suffered during the Holocaust and of current loss of resources due to terror attacks on their distress level. Twenty one percent of the sample had probable PTSD and high psychological distress levels in general. Current loss of psychosocial resources contributed significantly to survivors' current PTSD symptomatology and general psychological distress, above the contribution of the previous Holocaust-related loss. Our findings support COR theory, which states that traumatic events are associated with ongoing and often rapid loss of resources. Resource loss, in turn, is associated with higher distress levels. Moreover, current loss of resources compounds the impact of earlier resource losses incurred during the Holocaust.

    Background High fear of cancer recurrence (FCR) is an understudied topic in prostate cancer (PCa) survivors. This study aimed to detect the prevalence, consequences and characteristics associated with high FCR in PCa survivors. Material and methods This cross-sectional study included patients diagnosed with localized PCa and treated with curative radical prostatectomy between 1992 and 2012. We administered the Cancer Worry Scale (CWS) to assess FCR severity (primary outcome measure). Secondary outcomes included distress, quality of life (QOL), post-traumatic symptoms, and multidimensional aspects of FCR. χ(2)-tests, t-tests and Pearson's correlations examined the relationship between FCR and medical/demographic characteristics. MANOVA analyses and χ2-tests identified differences between PCa survivors with high and low FCR. Results Two hundred eighty-three PCa survivors (median age of 70.0 years) completed the questionnaires a median time of 7.1 years after surgery. About a third (36%) of all PCa survivors experienced high FCR. High FCR was associated with lower QOL, more physical problems, higher distress and more post-traumatic stress symptoms. PCa survivors with high FCR reported disease-related triggers (especially medical examinations), felt helpless and experienced problems in social relationships. High FCR was associated with a younger age and having received adjuvant radiotherapy. Conclusions Results illustrate that FCR is a significant problem in PCa survivors. Younger men and those treated with adjuvant radiotherapy are especially at risk. Those with high FCR experience worse QOL and higher symptom burden. Health care providers should pay specific attention to this problem and provide appropriate psychosocial care when needed. PMID:26935517

    The transition from breast cancer patient to survivor is associated with many treatment-related and psychosocial factors, which can influence health behaviour and associated needs. First, this study aimed to identify clusters of treatment-related and psychosocial factors among breast cancer survivors. Second, clusters' physical activity levels and care needs for physical activity were evaluated. Breast cancer survivors (n= 440; 52 ± 8 years) (3 weeks to 6 months post treatment) completed self-reports on physical and psychological symptoms; illness representations; social support and coping; physical activity and care needs for physical activity. Analyses identified four clusters: (1) a low distress-active approach group; (2) a low distress-resigned approach group; (3) a high distress-active approach group; and (4) a high distress-emotional approach group. Physical activity levels were higher in the low distress groups than in the high distress-emotional approach group. However, women with low distress and an active approach reported equal care needs for physical activity than women with high distress and an emotional approach. These findings suggest that care needs for physical activity are unrelated to distress and actual physical activity levels. The results emphasise the importance of screening for needs and provide a framework supporting the referral of breast cancer survivors to tailored interventions.

    Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed. PMID:24799477

    This article describes development of a quality of life measure designed to assess issues relevant to long-term cancer survivors. In-depth semi-structured interviews were conducted with 58 long-term cancer survivors to identify domains most relevant to long-term survivors (> or = 5 years post-diagnosis). Self-report items were developed from these interviews and administered to a second sample of 242 long-term survivors. Domains and items were selected from the item pool by a combination of factor analysis and criterion-based item selection. Five cancer-specific domains were identified (appearance concerns, financial problems, distress over recurrence, family-related distress, and benefits of cancer) along with seven generic QOL domains (negative feelings, positive feelings, cognitive problems, sexual problems, physical pain, fatigue, and social avoidance). Cronbach's alpha was 0.72 or greater for each domain. Correlations between domain scores and criterion measures were 0.72 or higher in all but one generic domain (social avoidance), but somewhat lower on cancer-specific domains. The new multidimensional measure has good internal consistency and validity and is appropriate for comparisons between cancer and non-cancer populations, as well as long-term follow-up of cancer patients.

    Purpose/Objectives To determine the effect that age at diagnosis has on fear of breast cancer recurrence and to identify the predictors of fear of recurrence using self-efficacy as a mediator. Design Cross-sectional survey. Setting Two university cancer centers and one cooperative group in the midwestern United States. Sample 1,128 long-term survivors. Methods Survivors were eligible if they were aged 18–45 years (younger group) or 55–70 years (older group) at cancer diagnosis, had received chemotherapy, and were three to eight years postdiagnosis. Fear of recurrence was compared between younger and older groups. Multiple regression analyses were used to test variables’ prediction of fear of recurrence and breast cancer survivor self-efficacy, as well as breast cancer survivor self-efficacy mediation effects. Main Research Variables Fear of recurrence, breast cancer survivor self-efficacy, and age at diagnosis. Findings Survivors diagnosed at a younger age had significantly higher fear of recurrence, as well as health, role, womanhood, death, and parenting worries. Perceived risk of recurrence, trait anxiety, and breast cancer reminders explained significant variance in fear of recurrence and breast cancer survivor self-efficacy. Breast cancer survivor self-efficacy partially mediated the effects of variables on fear of recurrence. Conclusions The findings suggest that breast cancer survivor self-efficacy may have a protective effect for survivors who are younger at diagnosis and have higher perceived risk of recurrence, higher trait anxiety, and more breast cancer reminders. Oncology nurses already use the skills required to support self-efficacy. Additional research is needed to define and test breast cancer survivor self-efficacy interventions. Implications for Nursing Oncology nurses are in a key role to assess fear of recurrence and provide self-efficacy interventions to reduce it in breast cancer survivors.

    The incidence of survivors of childhood sexual abuse (CSA) diagnosed with cancer is unknown. It is estimated that one in three women and one in six men in the United States are survivors of CSA. Survivors of CSA diagnosed with cancer are presented with multiple and potentially accumulating traumas. The re-traumatizing nature of a cancer diagnosis and treatment affects all elements of the CSA survivor's care and may impede her/his treatment. To date, the impact of CSA on the medical treatment of people with cancer has been unexplored with the existing studies on female survivors of CSA with cancer focusing on the post-treatment experience and their higher incidence of sexual dysfunction. This article describes the impact of CSA on the cancer treatment of 18 survivors of CSA and the clinical interventions used to address the unique psychosocial needs of this population. Anecdotal information suggests that the survivors of CSA may find aspects of the cancer experience reminiscent of their history of abuse. All 18 survivors of CSA experienced distressing memories of their abuse during their cancer treatment. Fifteen CSA survivors presented traumatic memories that were inaccessible to conscious thought processes prior to their cancer diagnosis. Psychodynamic interventions address issues of disruption in the cancer treatment, non-adherence, and difficulties in relationships with the health care team. Containment of intense affect and distressing thoughts rather than exploration improved CSA survivors' adherence with cancer treatments. The acquisition of self-comforting skills helped CSA survivors feel less re-victimized by their cancer experience. The establishment of an environment of internal and external safety improved communication with the health care team. Health care/psychosocial clinicians' awareness and use of appropriate interventions can minimize the affects of re-traumatization and enhance the CSA survivor's treatment experience.

    The precocial nature of orofacial sensorimotor control underscores the biological importance of establishing ororythmic activity in human infants. The purpose of this study was to assess the effects of comparable doses of three forms of orosensory experience, including a low-velocity spectrally reduced orocutaneous stimulus (NT1), a high-velocity broad spectrum orocutaneous stimulus (NT2), and a SHAM stimulus consisting of a blind pacifier. Each orosensory experience condition was paired with gavage feedings 3x/day for 10 days in the neonatal intensive care unit (NICU). Four groups of preterm infants (N=214), including those with respiratory distress syndrome (RDS), chronic lung disease (CLD), infants of diabetic mothers (IDM), and healthy controls (HI) were randomized to the type of orosensory condition. Mixed modeling, adjusted for gender, gestational age, postmenstrual age, and birth weight, demonstrated the most significant gains in non-nutritive suck (NNS) development among CLD infants who were treated with the NT2 stimulus, with smaller gains realized among RDS and IDM infants. The broader spectrum of the NT2 stimulus maps closely to known response properties of mechanoreceptors in lip, tongue, and oral mucosa and is more effective in promoting NNS development among preterm infants with impaired oromotor function compared to the low-velocity, spectrally reduced NT1 orosensory stimulus.

    Although fear of recurrence is a major concern among breast cancer survivors after surgery, no standard strategies exist that alleviate their distress. This study examined the association of patients' problem-solving skills and fear of recurrence and psychological distress among breast cancer survivors. Randomly selected, ambulatory, female patients with breast cancer participated in this study. They were asked to complete the Concerns about Recurrence Scale (CARS) and the Hospital Anxiety and Depression Scale. Multiple regression analyses were used to examine their associations. Data were obtained from 317 patients. Patients' problem-solving skills were significantly associated with all subscales of fear of recurrence and overall worries measured by the CARS. In addition, patients' problem-solving skills were significantly associated with both their anxiety and depression. Our findings warrant clinical trials to investigate effectiveness of psychosocial intervention program, including enhancing patients' problem-solving skills and reducing fear of recurrence among breast cancer survivors.

    While clinical reports suggest that torture survivors may try to suppress their emotions during torture, little is known about the use of emotional suppression following torture. In this study, 82 refugees and asylum-seekers (including 33 torture survivors) completed self-report measures of trait suppression, PTSD symptoms and baseline negative affect before being exposed to images depicting scenes of interpersonal trauma. The use of suppression while viewing the images was indexed and negative affect was measured both immediately after viewing the images and following a five minute rest period. Findings indicated that torture survivors did not show higher rates of trait suppression or state emotional suppression during the experimental session compared to non-torture survivors. However, torture survivors who endorsed state suppression higher levels of distress, and this relationship was especially strong for those with more severe PTSD symptoms. In contrast, there was a negative relationship between state suppression and distress for non-torture survivors with high levels of PTSD symptoms. These findings suggest that, while torture exposure does not lead to greater use of suppression, it does influence the impact of suppression on emotional responses to stimuli. PMID:27294797

    We analyzed the outcomes of patients who survived disease-free for 1 year or more after a second allogeneic hematopoietic cell transplantation (HCT) for relapsed acute leukemia or myelodysplastic syndromes between 1980 and 2009. A total of 1285 patients received a second allogeneic transplant after disease relapse; among these, 325 were relapse free at 1 year after the second HCT. The median time from first to second HCT was 17 and 24 months for children and adults, respectively. A myeloablative preparative regimen was used in the second transplantation in 62% of children and 45% of adult patients. The overall 10-year conditional survival rates after second transplantation in this cohort of patients who had survived disease-free for at least 1 year was 55% in children and 39% in adults. Relapse was the leading cause of mortality (77% and 54% of deaths in children and adults, respectively). In multivariate analyses, only disease status before second HCT was significantly associated with higher risk for overall mortality (hazard ratio, 1.71 for patients with disease not in complete remission before second HCT, P < .01). Chronic graft-versus-host disease (GVHD) developed in 43% and 75% of children and adults after second transplantation. Chronic GVHD was the leading cause of nonrelapse mortality, followed by organ failure and infection. The cumulative incidence of developing at least 1 of the studied late effects within 10 years after second HCT was 63% in children and 55% in adults. The most frequent late effects in children were growth disturbance (10-year cumulative incidence, 22%) and cataracts (20%); in adults they were cataracts (20%) and avascular necrosis (13%). Among patients with acute leukemia and myelodysplastic syndromes who receive a second allogeneic HCT for relapse and survive disease free for at least 1 year, many can be expected to survive long term. However, they continue to be at risk for relapse and nonrelapse morbidity and mortality. Novel

    Falls and fall-related injuries are important issue among polio survivors. The purpose of this study was to determine the incidence of, and consequences and factors associated with falls among Korean polio survivors. A total of 317 polio survivors participated in this study. All participants completed a questionnaire including fall history, symptoms related to post-polio syndrome and other information through a telephone interview. Among them, 80 participants visited our clinic for additional physical measurements and tests. Of the 317 respondents, 68.5% reported at least one fall in the past year. Of the fallers, 42.5% experienced at least one fall during one month. Most falls occurred during ambulation (76.6%), outside (75.2%) and by slipping down (29.7%). Of fallers, 45% reported any injuries caused by falls, and 23.3% reported fractures specifically. Female sex, old age, low bone mineral density, the presence of symptoms related to post-polio syndrome (PPS), poor balance confidence, short physical performance battery and weak muscle strength of knee extensor were not significantly associated with falls. Only leg-length discrepancy using spine-malleolar distance (SMD) was a significant factor associated with falls among Korean polio survivors. Our findings suggest that malalignment between the paralytic and non-paralytic limb length should be addressed in polio survivors for preventing falls. PMID:26839487

    Abstract Background: Care of the gynecologic cancer survivor extends beyond cancer treatment to encompass promotion of sexual, cardiovascular, bone, and brain health; management of fertility, contraception, and vasomotor symptoms; and genetic counseling. Methods: This is a narrative review of the data and guidelines regarding care and surveillance of the gynecologic cancer survivor. We searched databases including PubMed, Cochrane, and Scopus using the search terms gynecologic cancer, cancer surveillance, and cancer survivor and reached a consensus for articles chosen for inclusion in the review based on availability in the English language and publication since 2001, as well as key older articles, consensus statements, and practice guidelines from professional societies. However, we did not undertake an extensive systematic search of the literature to identify all potentially relevant studies, nor did we utilize statistical methods to summarize data. We offer clinical recommendations for the management of gynecologic cancer survivors based on review of evidence and our collective clinical experience. Results: Key messages include the limitations of laboratory studies, including CA-125, and imaging in the setting of gynecologic cancer surveillance, hormonal and non-hormonal management of treatment-related vasomotor symptoms and genitourinary syndrome of menopause, as well as recommendations for general health screening, fertility preservation, and contraception. Conclusions: A holistic approach to care extending beyond cancer treatment alone benefits gynecologic cancer survivors. In addition to surveillance for cancer recurrence and late treatment side effects, survivors benefit from guidance on hormonal, contraceptive, and fertility management and promotion of cardiovascular, bone, brain, and sexual health.

    In the absence of direct toxins, the majority of evidence from animal models suggests that neutrophils (PMN) are necessary for the full expression of the abnormal pulmonary permeability accompanying acute microvascular lung injury. We therefore studied the role of the PMN in the human correlate of this disease, the adult respiratory distress syndrome (ARDS), by assessing the pulmonary retention of infused autologous /sup 111/Indium-labeled PMN (PMN-In). We evaluated 79 patients, prospectively categorized as: active ARDS (Aa; n = 30), active ARDS and concurrent corticosteroid therapy (As; n = 11), resolving ARDS (Ar; n = 13), sepsis without pulmonary edema (S; n = 7), and cardiac pulmonary edema (C; n = 18). This clinical separation was confirmed by retrospective analysis of associated measures of hemodynamic and respiratory dysfunction. We found that both analog scintigrams (positive/negative for diffuse pulmonary PMN-In sequestration) and computer-assisted quantitative analysis in 46 patients (T 1/2 of first hour demargination and percentage of peak activity/pixel/second remaining at 17 to 20 h) showed a significant rank order decrease in the pulmonary retention of labeled PMN-In through the Groups Aa----As----S----Ar----C. Our findings recognized aspects of in vivo PMN-In behavior that implied pathophysiologic differences between groups of critically ill patients in either the PMN themselves or in PMN-pulmonary endothelial interaction. This demonstrates the possibility of abnormal in vivo PMN-endothelial interaction in ARDS by virtue of the greater pulmonary localization of PMN in active ARDS versus resolving disease, septic non-ARDS states, and cardiac pulmonary edema.

    Background: Nowadays, establishment of nCPAP and surfactant administration is considered to be the first level of intervention for newborns engaged in the process of Respiratory Distress Syndrome (RDS). In order to decrease the side effects of the nCPAP management placed in noninvasive-non-cycled respiratory support. Noninvasive-cycled respiratory support mechanism have been developed such as N-BiPAP. Therefore, we compared N-BiPAP with Bubble-CPAP in a clinical trial. Materials and Methods: This research was done as an on newborns weighing less than 1500 grams affiliated with RDS. A3 The total number of newborns was 70. Newborns were divided into two groups with the sample size of 35 patients in each, according to odd and even document numbers. One group was treated with N-BiPAP and the other with Bubble-CPAP. Patients were compared according to the length of treatment with noninvasive respiratory support, length of oxygen intake, number of surfactant doses administered, need for invasive mechanical ventilation, apnea, patent ductus arteriosus (PDA), chronic lung disease, intraventricular hemorrhage, pneumothorax, and death. Data was recorded and compared. Results: The average duration for noninvasive respiratory support and the average time of need to complementary oxygen was not significantly different in both groups (P value > 0.05). Need for invasive ventilation, also chronic lung disease, intraventricular hemorrhage (IVH), pneumothorax, need for the next dose of surfactant, and the death rate did also have no meaningful difference. (P value > 0.05). Conclusion: In this research N-BiPAP did not show any obvious clinical preference over the Bubble-CPAP in treatment of newborns weighing less than 1500 grams and affiliated with RDS. PMID:26955624

    This study addressed long-term effects of extreme trauma among Holocaust survivors (N = 126) in an older (75-94 years) sample of the Israeli Jewish population. Survivors were compared with European-descent groups that had immigrated either before World War II (n = 206) or after (n = 145). Participants in the latter group had had Holocaust-related life histories but did not consider themselves survivors. Controlling for sociodemographics, the results indicated that survivors fared worse than prewar immigrants in certain psychosocial domains, mainly cumulative distress and activity, rather than in health-related ones. Survivors and postwar immigrant comparisons had almost no differences. The study highlights the need for a wide view of functioning facets and comparison groups in delineating late posttraumatic effects.

    Fourteen months after the 2004 tsunami, mental health outcome was assessed in 187 bereaved relatives, 308 bereaved friends, and in 3,020 nonbereaved Swedish survivors. Of the bereaved relatives, 41% reported posttraumatic stress reactions and 62% reported impaired general mental health. Having been caught or chased by the tsunami in combination with bereavement was associated with increased posttraumatic stress reactions. Complicated grief reactions among relatives were almost as frequent as posttraumatic stress reactions. The highest levels of psychological distress were found among those who had lost children. Traumatic bereavement, in combination with exposure to life danger, is probably a risk factor for mental health sequelae after a natural disaster.

    We have created a mindfulness approach to treat patients who experience multiple, persistent, and disabling physical symptoms that cannot be explained by a well-defined medical or surgical condition. Randomized controlled trials in this area are few, and research is hampered by the lack of clear definitions. Bodily distress syndrome (BDS) or bodily stress is an empirically defined definition unifying various conditions such as fibromyalgia, chronic fatigue syndrome, and somatization disorder. In the present PhD, we explored whether patients suffering from BDS may be committed to mental training in the form of mindfulness therapy, which is a mindfulness program specifically targeted patients suffering from BDS. The theoretical model for including mindfulness training in the treatment of BDS is based on identified neurobiological impairments in these patients and the neurobiological improvements that mindfulness training may offer. BDS is a major public health issue possibly associated with the pathology of the immuno-endocrine and autonomic nervous system. BDS patients are often stigmatized, and effective treatment is rarely delivered, which leaves these patients isolated, left by themselves, vulnerable to potentially harming medical and/or alternative treatments. Accordingly, there is a need for non-harming practical tools that patients can learn to master so that they can improve the ability to take responsibility for their own health and wellbeing. Mindfulness-Based Stress Reduction (MBSR) is a group program that employs mindfulness practice to alleviate suffering associated with physical, psychosomatic, and psychiatric disorders. Mindfulness-Based Cognitive Therapy (MBCT) is designed to prevent depressive relapse. Paper I and II present systematic literature reviews only of randomized controlled trials on MBSR and MBCT. The effect of MBSR has been explored on fibromyalgia in three studies, none of them showed convincing results, but gave some indications as to

    We hypothesized that the corticospinal system undergoes functional changes in long-term polio survivors. Central motor conduction times (CMCTs) to the four limbs were measured in 24 polio survivors using transcranial magnetic stimulation (TMS). Resting motor thresholds and CMCTs were normal. In 17 subjects whose legs were affected by polio and 13 healthy controls, single- and paired-pulse TMS was used to assess motor cortex excitability while recording from tibialis anterior (TA) muscles at rest and following maximal contraction until fatigue. In polio survivors the slope of the recruitment curve was normal, but maximal motor evoked potentials (MEPs) were larger than in controls. MEPs were depressed after fatiguing exercise. Three patients with central fatigue by twitch interpolation had a trend toward slower recovery. There was no association with symptoms of post-polio syndrome. These changes occurring after polio may allow the motor cortex to activate a greater proportion of the motor neurons innervating affected muscles.

    This phenomenological study describes the essential structure of the lived experience of adult male survivors of childhood sexual abuse by clergy (AMSCSABC). A purposive sample of seven AMSCSABC related their subjective experiences in semistructured interviews. Colaizzi's (1978) phenomenological method was used for data analysis. Survivors describe a bifurcated rage and spiritual distress that pervades their entire "lifebeing." Learning about AMSCSABC will assist nurses to identify potential risk factors of childhood sexual abuse by clergy (CSABC), design prevention strategies, and enhance empathy for a healing relationship.

    Cancer diagnoses and treatment may have long-term effects on fertility. Semistructured interviews were administered to young cancer survivors (<20 years) and their parents (n = 97). Fertility related concerns were reported by 45 participants (46.4%). Themes included: distress regarding potential infertility; the effect of infertility on future relationships, self-esteem, and miscommunications/confusion about fertility status; access to fertility testing; and preservation options. Parents also reported challenges regarding how and when it was developmentally appropriate to talk to their children about fertility. The development of comprehensive consumer-driven approaches to managing the fertility concerns of young survivors and their families is essential. PMID:27269305

    Although trauma exposure is common, few people develop acute and chronic psychiatric disorders. Those who develop posttraumatic stress disorder likely have coexisting psychiatric and physical disorders. Psychiatric nurses must be knowledgeable about trauma responses, implement evidence-based approaches to conduct assessments, and create safe environments for patients. Most researchers assert that trauma-focused cognitive-behavioral approaches demonstrate the most efficacious treatment outcomes. Integrated approaches, offer promising treatment options. This article provides an overview of clinical factors necessary to help the trauma survivor begin the process of healing and recovery and attain an optimal level of functioning. PMID:27229285

    Objective: The purpose of this study was to describe the moral distress among Iranian registered nurses. Methods: This was a descriptive –analytic study, in which 264 out of 1000 nurses were randomly selected as a sample group and completed the questionnaire. The nurses’ moral distress was assessed using Corley’s 30-item Moral Distress Scale adapted for use in an Iranian population. The collected data were analyzed by SPSS version 19. Results: In this study, no correlation was found between the level of moral distress and any of the demographic data. The mean moral distress score ranged from 3.56 to 5.83, indicating moderate to high levels of moral distress. The item with the highest mean score was “working with unsafe levels of nurse staffing”. The item with the lowest mean score was “giving medication intravenously to a patient who has refused to take it”. Nurses working in EMS and NICU units had the highest levels of moral distress. Conclusion: A higher degree of moral distress is observed among nurses who work in health care systems. The results of this study highly recommend practical and research-oriented evaluation of moral distress in the medical society in Iran. Our findings suggest that Iranian version of MDS is a reliable instrument to measure moral distress in nurses. PMID:26005478

    Background: There has been no external validation of survival prediction models for severe adult respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO) therapy in China. The aim of study was to compare the performance of multiple models recently developed for patients with ARDS undergoing ECMO based on Chinese single-center data. Methods: A retrospective case study was performed, including twenty-three severe ARDS patients who received ECMO from January 2009 to July 2015. The PRESERVE (Predicting death for severe ARDS on VV-ECMO), ECMOnet, Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score, a center-specific model developed for inter-hospital transfers receiving ECMO, and the classical risk-prediction scores of Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) were calculated. In-hospital and six-month mortality were regarded as the endpoints and model performance was evaluated by comparing the area under the receiver operating characteristic curve (AUC). Results: The RESP and APACHE II scores showed excellent discriminate performance in predicting survival with AUC of 0.835 (95% confidence interval [CI], 0.659–1.010, P = 0.007) and 0.762 (95% CI, 0.558–0.965, P = 0.035), respectively. The optimal cutoff values were risk class 3.5 for RESP and 35.5 for APACHE II score, and both showed 70.0% sensitivity and 84.6% specificity. The excellent performance of these models was also evident for the pneumonia etiological subgroup, for which the SOFA score was also shown to be predictive, with an AUC of 0.790 (95% CI, 0.571–1.009, P = 0.038). However, the ECMOnet and the score developed for externally retrieved ECMO patients failed to demonstrate significant discriminate power for the overall cohort. The PRESERVE model was unable to be evaluated fully since only one patient died six months postdischarge. Conclusions: The RESP, APCHAE II, and SOFA scorings

    In the present study, the regulatory effect of cytokine-induced neutrophil chemoattractant (CINC) and epithelial neutrophil-activating peptide 78 (ENA-78) on pulmonary neutrophil (PMN) accumulation in lipopolysaccharide (LPS)-induced acute respiratory distress syndrome (ARDS) mice, and the therapeutic effect of pyrrolidine dithiocarbamate (PDTC), was investigated. BALB/c mice were divided into control, LPS and PDTC + LPS groups using a random number table. The phosphorylation of nuclear factor-κB (NF-κB) was detected using a western blot, and the mRNA expression levels of CINC were evaluated using reverse transcription-quantitative polymerase chain reaction. The expression of NF-κB, CINC and ENA-78 was detected using immunohistochemistry. The production of interleukin (IL)-8 and IL-10 in serum and broncho-alveolar lavage fluid (BALF) was analyzed using an enzyme-linked immunosorbent assay. The total number of leukocytes and proportion of PMNs in BALF was also determined. Following injection with LPS (20 mg/kg), the expression levels of p-NF-κB, CINC and ENA-78 were increased in lung tissue, and the expression levels of IL-8, IL-10 and the number of PMNs increased in serum and BALF. However, in comparison with the LPS group, the degree of lung injury was reduced in ARDS mice that were treated with PDTC. In addition, the expression level of p-NF-κB and the production of chemokines in lung tissue decreased in ARDS mice that were treated with PDTC, and the number of PMNs in BALF also decreased. In conclusion, the results of the present study suggest that the LPS-induced phosphorylation of NF-κB may result in the synthesis and release of CINC and ENA-78, which induce the accumulation of PMNs in the lung. Therefore, PDTC may be used to reduce the production of chemokines and cytokines, thereby decreasing the activation of PMNs in lung tissue and reducing the damage of lung tissue in ARDS.

    2012-01-01

    Introduction Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is characterized by features other than increased pulmonary vascular permeability. Pulmonary vascular permeability combined with increased extravascular lung water content has been considered a quantitative diagnostic criterion of ALI/ARDS. This prospective, multi-institutional, observational study aimed to clarify the clinical pathophysiological features of ALI/ARDS and establish its quantitative diagnostic criteria. Methods The extravascular lung water index (EVLWI) and the pulmonary vascular permeability index (PVPI) were measured using the transpulmonary thermodilution method in 266 patients with PaO2/FiO2 ratio ≤ 300 mmHg and bilateral infiltration on chest radiography, in 23 ICUs of academic tertiary referral hospitals. Pulmonary edema was defined as EVLWI ≥ 10 ml/kg. Three experts retrospectively determined the pathophysiological features of respiratory insufficiency by considering the patients' history, clinical presentation, chest computed tomography and radiography, echocardiography, EVLWI and brain natriuretic peptide level, and the time course of all preceding findings under systemic and respiratory therapy. Results Patients were divided into the following three categories on the basis of the pathophysiological diagnostic differentiation of respiratory insufficiency: ALI/ARDS, cardiogenic edema, and pleural effusion with atelectasis, which were noted in 207 patients, 26 patients, and 33 patients, respectively. EVLWI was greater in ALI/ARDS and cardiogenic edema patients than in patients with pleural effusion with atelectasis (18.5 ± 6.8, 14.4 ± 4.0, and 8.3 ± 2.1, respectively; P < 0.01). PVPI was higher in ALI/ARDS patients than in cardiogenic edema or pleural effusion with atelectasis patients (3.2 ± 1.4, 2.0 ± 0.8, and 1.6 ± 0.5; P < 0.01). In ALI/ARDS patients, EVLWI increased with increasing pulmonary vascular permeability (r = 0.729, P < 0.01) and was weakly

    Background Obesity and stress are among the most common lifestyle-related health problems. Most of the current disease prevention and management models are not satisfactorily cost-effective and hardly reach those who need them the most. Therefore, novel evidence-based controlled interventions are necessary to evaluate models for prevention and treatment based on self-management. This randomized controlled trial examines the effectiveness, applicability, and acceptability of different lifestyle interventions with individuals having symptoms of metabolic syndrome and psychological distress. The offered interventions are based on cognitive behavioral approaches, and are designed for enhancing general well-being and supporting personalized lifestyle changes. Methods/Design 339 obese individuals reporting stress symptoms were recruited and randomized to either (1) a minimal contact web-guided Cognitive Behavioral Therapy-based (CBT) intervention including an approach of health assessment and coaching methods, (2) a mobile-guided intervention comprising of mindfulness, acceptance and value-based exercises, (3) a face-to-face group intervention using mindfulness, acceptance and value-based approach, or (4) a control group. The participants were measured three times during the study (pre = week 0, post = week 10, and follow-up = week 36). Psychological well-being, lifestyles and habits, eating behaviors, and user experiences were measured using online surveys. Laboratory measurements for physical well-being and general health were performed including e.g. liver function, thyroid glands, kidney function, blood lipids and glucose levels and body composition analysis. In addition, a 3-day ambulatory heart rate and 7-day movement data were collected for analyzing stress, recovery, physical activity, and sleep patterns. Food intake data were collected with a 48 -hour diet recall interview via telephone. Differences in the effects of the interventions would be

    Existing models of trauma suggest that for recovery to occur, trauma related cues and emotions require awareness and openness while survivors continue committing action toward valued life aims (other than regulating emotions). Based on this theoretical framework, an unwillingness to be in contact with distressing thoughts and feelings (experiential avoidance) might operate together with posttraumatic distress to predict when people find benefits and meaning in the aftermath of trauma. We hypothesized that people reporting posttraumatic distress and less reliance on experiential avoidance would report greater posttraumatic growth and meaning in life compared with other trauma survivors. We administered questionnaires to 176 college students reporting at least one traumatic event. Results supported these moderation models. This is the fourth study (with different samples, measures, and methodologies) to provide evidence that a combination of excessive anxiety and a heavy reliance on experiential avoidance leads to attenuated well-being. We discuss the implications for understanding heterogeneous trauma reactions. PMID:21072251

    The purpose of this randomized control trial was to verify the effectiveness of a brief group intervention that combines stress management psycho-education and physical activity (ie, independent variable) intervention in reducing fatigue and improving energy level, quality of life (mental and physical), fitness (VO 2submax), and emotional distress (ie, dependent variables) in breast cancer survivors. This study applied Lazarus and Folkman stress-coping theoretical framework, as well as Salmon's unifying theory of physical activity. Eighty-seven French-speaking women who had completed their treatments for nonmetastatic breast cancer at a university hospital in Quebec City, Canada, were randomly assigned to either the group intervention (experimental) or the usual-care (control) condition. Data were collected at baseline, postintervention, and at 3-month follow-up. The 4-week group intervention was cofacilitated by 2 nurses. Results showed that participants in the intervention group showed greater improvement in fatigue, energy level, and emotional distress at 3-month follow-up, and physical quality of life at postintervention, compared with the participants in the control group. These results suggest that a brief psycho-educational group intervention focusing on active coping strategies and physical activity is beneficial to cancer survivors after breast cancer treatments.

    Congenital laryngeal atresia is a rare cause of respiratory distress of the newborn. The defect may be isolated or occur in association with other congenital abnormalities, notably the presence of a tracheoesophageal fistula, esophageal atresia, encephalocele, or Congenital High Airway Obstructive Syndrome (CHAOS). We present the case of a newborn with no identified intrapartum abnormalities with respiratory distress at birth secondary to near-complete laryngeal atresia. Management included tracheostomy, repeated endoscopic incisions, and serial balloon dilatations employing the topical use of Mitomycin C. Seven year follow-up was significant for mobilization of the true vocal cords bilaterally, as well as successful decannulation.

    Traumatic events in one's younger years can have an impact on how an individual copes with later life. One traumatic experience for Jewish individuals was the Holocaust. Some of these people are moving into long-term care facilities. It was within this context that the research question emerged: What are Holocaust survivor residents' perceptions of a life lived as they move into a long-term care facility? For this qualitative study, Holocaust survivors were individually interviewed. Findings emphasize that nursing care needs to ensure that Holocaust survivor residents participate in activities, receive timely health care, and receive recognition of their life experiences.

However, the mechanisms underlying this effect remain underexplored. The purpose of the paper is to show that reduced organizational identification can serve as an explanation for the survivor syndrome. We conducted a laboratory experiment, in which participants work as a group of employees for another participant who acts as employer. In the course of the experiment, the employer decides whether one of his or her employees should be laid off or not. Mediation analysis supports a social identity-based explanation for the emergence of the survivor syndrome: downsizing causes lower identification with the employer which in turn relates to lower performance of employees.

    Disasters greatly threaten the health and lives of people all over the world. Japan experienced severe damage following the Great East Japan Earthquake on March 11, 2011, and some survivors continue to live in prefabricated temporary housing, built collectively in damaged areas. Previous studies have shown that social relationships in such communities have the potential to protect the mental health of disaster survivors. We examined the association between survivors' social support and social participation in 2012 and their psychological distress in 2013 using the K6 scale. Self-reported questionnaires were distributed to all 15,979 households in prefabricated temporary housing in eight municipalities in Miyagi prefecture in 2012, and 19,284 adults from 9366 (58.6%) households responded. One year later, 10,880 adults responded to a follow-up survey. Multivariate multilevel linear regression analyses with multiply imputed datasets showed that survivors' psychological distress at follow-up significantly differed between communities (community-level variance [standard error] = 0.38 [0.13]). The variance was reduced to 0.25 [0.09] after considering individual demographic characteristics and psychological distress at baseline. Individual- and community-level social relationships of 7.1% and 15.8%, respectively, explained the difference. After adjusting for covariates including K6 scale at baseline, individual-level social support, community-level social support, and individual-level social participation were significantly associated with low psychological distress at follow-up (coefficients [95% confidence intervals] were: -0.54 [-0.79, -0.30]; -0.43 [-0.72, -0.14]; and -0.22 [-0.40, -0.04], respectively).

    Thousands of orphaned survivors of the 1994 Rwandan Genocide against the Tutsi were not only exposed to extraordinarily severe forms of violence, but also many of these children took on the responsibility of caring and providing for other child survivors. This study describes the poverty, educational attainment, social support and mental health of orphaned heads of household (OHH) fourteen years after the genocide, and analyzes how violence exposure during the genocide and post-genocide stressors contributed to symptoms of posttraumatic stress disorder (PTSD) and distress. Participants were 61 members of an OHH community organization who were interviewed in 2002 about their genocide experiences and who provided a follow-up assessment of post-genocide risk factors and PTSD and distress symptoms in 2008. Almost all of the OHH in this study reported low social support, high levels of poverty, and high rates of PTSD and distress symptoms. Lower educational attainment predicted PTSD symptoms and partially mediated the association between exposure to genocide violence and PTSD. Distress was predicted by lack of social support and witnessing family members harmed during the genocide. Results suggest that public health and community efforts to improve educational outcomes and to strengthen and expand social support networks may improve mental health outcomes of OHH. PMID:26236560

  18. Objective and subjective stressors and the psychological adjustment of melanoma survivors.

    2007-04-01

    This study of 300 melanoma survivors examines the relative contributions of objective illness-related factors (stage of illness at diagnosis, time since diagnosis, and change in physical condition) and of subjective factors (cognitive appraisal) to their psychological adjustment. The findings show that lower appraisal of their situation as a threat, higher appraisal of it as a challenge, and higher appraisal of their subjective ability to cope with it all increased their well-being, while lower threat appraisal and higher appraisal of subjective ability to cope also reduced their distress. These findings, which are consistent with Lazarus and Folkman's stress coping theory, suggest that subjective factors may be more important than objective medical factors in predicting patients' adjustment. With this, more advanced stage at diagnosis contributed to reducing distress, while being married contributed both to higher well-being and reduced distress.

    Rationale: Persistent symptoms of psychological distress represent an unmet need among intensive care unit (ICU) survivors. Objectives: We aimed to develop and pilot test a simple telephone-based mindfulness training intervention to address this population’s unique needs. Methods: Open trial involving survivors of medical and surgical critical illness and their informal caregivers, using a pretest–posttest design. Measurements and Main Results: We developed a six-session, telephone-delivered, ICU survivor–specific mindfulness intervention based on past focus groups, the medical literature, and the precedent of the most effective components of existing mindfulness programs. A total of 11 survivors of mechanical ventilation were enrolled, together with 2 informal caregivers for exploratory purposes. Three patients dropped out before intervention initiation because of progressive illness or severe social stressors. Of the 10 remaining participants, 8 (80%) completed the program within 7 weeks. Among these eight patients and caregivers who completed all study procedures, six (75%) experienced improvement in symptoms of psychological distress (anxiety, depression, or post-traumatic stress disorder). Changes in distress symptoms were correlated with improvement in mindfulness qualities, adaptive coping, and emotion regulation. Participants reported high satisfaction with the program in postintervention interviews. Conclusions: A new ICU survivor–specific mindfulness training intervention delivered by telephone was acceptable and feasible. Changes in symptoms of distress were correlated with changes in skills that were targeted by the mindfulness program. Controlled trials are needed to further evaluate this promising intervention.

    Simarski, Lynn Teo

    If arguments for limiting support for science continue to dominate the public discourse about science, “we will be talking our way into scientific decline,” said Frank Press, president of the National Academy of Sciences, to the academy's annual meeting on April 30. Press is the latest in a number of prominent figures on the Washington science scene, from George E. Brown, Jr. (D-Calif.), chairman of the House Science Committee, to Mary L. Good, head of the National Science Board, to take stock of the U.S. science enterprise.Press lauded President Bush's current budget request for science, calling it the best one in recent years. The new federal budget caps, however, provide a counterweight by creating a “fixed pie” for spending. Added to this, the university science community is in severe distress, Press said, suffering from outmoded laboratories, rising costs, budget cuts, and new and expensive government regulations, among other burdens. The budget caps also force federally funded laboratories and universities to compete with each other for support.

  1. Yoga as Treatment for Insomnia Among Cancer Patients and Survivors: A Systematic Review.

    PubMed

    Mustian, Karen M

    2013-11-01

    Many cancer patients and survivors, between 15 to 90%, report some form of insomnia or sleep quality impairment during and post-treatment, such as excessive daytime napping, difficulty falling asleep, difficulty staying asleep, and waking up too early. Insomnia and sleep quality impairment are among the most prevalent and distressing problems reported by cancer patients and survivors, and can be severe enough to increase cancer mortality. Despite the ubiquity of insomnia and sleep quality impairment, they are under-diagnosed and under-treated in cancer patients and survivors. When sleep problems are present, providers and patients are often hesitant to prescribe or take pharmaceuticals for sleep problems due to poly pharmacy concerns, and cognitive behavioral therapy for insomnia can be very difficult and impractical for patients to adhere to throughout the cancer experience. Research suggests yoga is a well-tolerated exercise intervention with promising evidence for its efficacy in improving insomnia and sleep quality impairment among survivors. This article provides a systematic review of existing clinical research on the effectiveness of yoga for treating insomnia and sleep quality impairment among cancer patients and survivors.

  2. Posttraumatic stress disorder among injured survivors of a terrorist attack. Predictive value of early intrusion and avoidance symptoms.

    1992-08-01

    Fifteen injured survivors of a terrorist attack on a civilian bus were followed during their admission, and 12 of the 14 living survivors were examined 10 months later. A substantial amount of distress was found, in the entire group, across the study. Four patients (33%) suffered from diagnosable PTSD on follow-up. Symptoms of intrusion and denial, recorded during admission, failed to predict PTSD, and were not significantly correlated with psychiatric symptoms on follow-up. This paper discusses the finding of low predictive validity of early PTSD symptoms, and suggests that measures of arousal should be added to those of cognitive symptoms in future prospective studies of traumatic stress.

    2015-05-15

    Young adult childhood cancer survivors are at an increased risk of frailty, a physiologic phenotype typically found among older adults. This phenotype is associated with new-onset chronic health conditions and mortality among both older adults and childhood cancer survivors. Mounting evidence suggests that poor fitness, muscular weakness, and cognitive decline are common among adults treated for childhood malignancies, and that risk factors for these outcomes are not limited to those treated with cranial radiation. Although the pathobiology of this phenotype is not known, early cellular senescence, sterile inflammation, and mitochondrial dysfunction in response to initial cancer or treatment-related insults are hypothesized to play a role. To the authors' knowledge, interventions to prevent or remediate frailty among childhood cancer survivors have not been tested to date. Pharmaceutical, nutraceutical, and lifestyle interventions have demonstrated some promise.

  6. A Practical Solution for Dyspareunia in Breast Cancer Survivors: A Randomized Controlled Trial

    2015-01-01

    Purpose Dyspareunia is common in breast cancer survivors because of low estrogen. This study explored whether dyspareunia is introital pain, preventable with analgesic liquid. Patients and Methods In a randomized, controlled, double-blind trial, estrogen-deficient breast cancer survivors with severe penetrative dyspareunia applied either saline or 4% aqueous lidocaine to the vulvar vestibule for 3 minutes before vaginal penetration. After a 1-month blinded trial of patient-assessed twice-per-week tampon insertion or intercourse, all patients received lidocaine for 2 months in an open-label trial. The primary outcome was patient-related assessment of penetration pain on a scale of zero to 10. Secondary outcomes were sexual distress (Female Sexual Distress Scale), sexual function (Sexual Function Questionnaire), and resumption of intercourse. Comparisons were made with the Mann-Whitney U and Wilcoxon signed rank test with significance set at P < .05. Results In all, 46 patients, screened to exclude those with pelvic muscle and organ pain, uniformly had clinical evidence of severe vulvovaginal atrophy, dyspareunia (median pain score, 8 of 10; interquartile range [IQR], 7 to 9), increased sexual distress scores (median, 30.5; IQR, 23 to 37; abnormal, > 11), and abnormal sexual function. Users of lidocaine reported less pain during intercourse in the blinded phase (median score of 1.0 compared with saline score of 5.3; P = .007). After open-label lidocaine use, 37 (90%) of 41 reported comfortable penetration. Sexual distress decreased (median score, 14; IQR, 3 to 20; P < .001), and sexual function improved in all but one domain. Of 20 prior abstainers from intercourse who completed the study, 17 (85%) had resumed comfortable penetrative intimacy. No partners reported penile numbness. Conclusion Breast cancer survivors with menopausal dyspareunia can have comfortable intercourse after applying liquid lidocaine compresses to the vulvar vestibule before penetration. PMID

    Purpose Latino cancer survivors experience lower psychosocial well-being compared to Non-Latino Whites. This study describes the development of a culturally-appropriate support group and reports on feasibility of implementation and preliminary outcomes. Methods Promotores (lay health workers) conducted all aspects of data collection and program implementation. Participants were 29 Spanish-speaking Latino cancer survivors (n=12 men, 17 women) who took part in one of three study phases. Phase 1 included one-on-one interviews and focus groups (n=14) to investigate psychosocial needs of survivors. During Phase 2, a 10-week program was developed that integrated data from Phase 1 and culturally-relevant concepts. Session topics included stress, nutrition, physical activity, body image, sexuality, medical advocacy and social support. In Phase 3, the program was implemented within gender-specific groups (n=15). Within-group pre-post comparisons of distress (distress thermometer, salivary cortisol) and quality of life (FACIT) were conducted. Follow-up focus groups assessed participant experience Results Phase 1 activities identified survivor needs and interests (e.g., isolation, family and spirituality, supporting other Latinos with cancer). Evidence of program feasibility was demonstrated (e.g., 90%–100% attendance, 100% data completion). While interpretation of significance is limited due to sample size, improvements in quality of life [functional (p=0.05), social (p=0.02), and meaning/purpose (p=0.05)] were observed among women but not men. Qualitative follow-up revealed high satisfaction with group participation, but discomfort with the topic of sexuality in women. Conclusions This project demonstrates development and feasibility outcomes for providing culturally-appropriate psychosocial support to Latino cancer survivors. Limitations, including lack of control group, and future directions are discussed. PMID:25556609

    2010-02-01

    Since sexual assault survivors are most likely to disclose their experiences to a friend; prevention efforts increasingly focus on friends as informal helpers. The current study examined friends' perceptions of the disclosure experience. Undergraduates (N=1,241) at the University of New Hampshire completed a shortened version of the Ahrens and Campbell (2000) Impact on Friends measure. Results found that about 1 in 3 female undergraduates and 1 in 5 male students were told by a friend that they were a victim of an unwanted sexual experience. Gender differences were found in friends' responses to disclosure. Women reported greater emotional distress in response to a friend's disclosure, greater positive responses and lesser-perceived confusion/ineffectiveness as compared to men. Implications include the need to develop specific and clear educational material to help the community cope with and effectively respond to unwanted sexual experiences on college campuses.

    2014-05-01

    This series of three patients is the first description of the presentation, clinical course, and endoscopic findings of nasogastric tube-related airway distress, or nasogastric tube syndrome, in infants. We identify key differences in disease features from those described in adults, based on our literature review. Specifically, infant nasogastric tube syndrome presented as significant respiratory distress and postcricoid inflammation without vocal fold immobility. Symptoms resolved more quickly (mean±SD, 2±1 days) than reported in adults. We suggest that nasogastric tube syndrome should be considered in infants with otherwise unexplained respiratory distress, even in the absence of impaired vocal fold mobility.

    2014-01-01

    There has been a dramatic increase in the number of childhood cancer survivors living to an old age due to improved cancer treatments. However, these survivors are at risk of numerous late effects as a result of their cancer therapy. Engaging in protective health behaviors and limiting health damaging behaviors are vitally important for these survivors given their increased risks. We reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings. We examine the prevalence of a variety of health behaviors among childhood cancer survivors, identify significant risk factors, and describe health behavior interventions for survivors.

    2012-04-01

    Using a cross-panel design and data from 2 successive cohorts of college students (N = 357), we examined the stability of maladaptive perfectionism, procrastination, and psychological distress across 3 time points within a college semester. Each construct was substantially stable over time, with procrastination being especially stable. We also tested, but failed to support, a mediational model with Time 2 (mid-semester) procrastination as a hypothesized mechanism through which Time 1 (early-semester) perfectionism would affect Time 3 (end-semester) psychological distress. An alternative model with Time 2 perfectionism as a mediator of the procrastination-distress association also was not supported. Within-time analyses revealed generally consistent strength of effects in the correlations between the 3 constructs over the course of the semester. A significant interaction effect also emerged. Time 1 procrastination had no effect on otherwise high levels of psychological distress at the end of the semester for highly perfectionistic students, but at low levels of Time 1 perfectionism, the most distressed students by the end of the term were those who were more likely to have procrastinated earlier in the semester. Implications of the stability of the constructs and their association over time, as well as the moderating effects of procrastination, are discussed in the context of maladaptive perfectionism and problematic procrastination.

    In the year following the 2010 Haiti earthquake, local earthquake survivors trained as lay mental health workers implemented a culturally-adapted, psychosocial and trauma-focused group intervention for residents of camps for internally displaced peoples (IDPs). Analysis of evaluation data collected at three Port-au-Prince IDP camps revealed decreased self-reported posttraumatic distress (measured using the Harvard Trauma Questionnaire) associated with participation in this intervention. Improvement occurred across all three PTSD symptom clusters (re-experiencing, avoidance, and hyperarousal). Female participants reported higher baseline distress, were more likely to participate in the intervention, and benefitted more than did men. Results provide initial support for the effectiveness of train-the-trainer interventions utilizing local lay disaster survivors.

    2007-11-01

    Torture survivors often report chronic debilitating physical and psychological distress. Prior research on the relationship between physical and psychological trauma suggests that the 2 are not independent. Injury sustained during torture may increase the likelihood of subsequent distress as either a moderator or mediator. For long-term psychopathology in a sample of Punjabi Sikh survivors of human rights violations (N = 116), chronic injuries mediated the path between torture and posttraumatic stress disorder, specifically the severity of numbing symptoms. Although injuries were associated with major depression, torture was not, and injuries did not moderate the relationship between major depression and torture. Chronic injuries may represent trauma severity or persistent traumatic cues. These findings emphasize connections between physical and psychological trauma and the importance of an interdisciplinary approach to torture treatment.

    2009-10-01

    Gynecologic cancer patients are at high risk for emotional distress and sexual dysfunction. The present study tested sexual self schema as an individual difference variable that might be useful in identifying those at risk for unfavorable outcomes. First, we tested schema as a predictor of sexual outcomes, including body change stress. Second, we examined schema as a contributor to broader quality of life outcomes, specifically as a moderator of the relationship between sexual satisfaction and psychological statue (depressive symptoms and quality of life). A cross-sectional design was used. Gynecologic cancer survivors (N = 175) 2-10 years post treatment were assessed during routine follow up. In regression analyses controlling for sociodemographic variables, patients' physical symptoms/signs as evaluated by nurses, health status, and extent of partner sexual difficulties, sexual self schema accounted for significant variance in the prediction of current sexual behavior, responsiveness, and satisfaction. Moreover, schema moderated the relationship between sexual satisfaction and psychological outcomes, suggesting that a positive sexual self schema might "buffer" patients from depressive symptoms when their sexual satisfaction is low. Furthermore, the combination of a negative sexual self schema and low sexual satisfaction might heighten survivors' risk for psychological distress, including depressive symptomatology. These data support the consideration of sexual self schema as a predictor of sexual morbidity among gynecologic cancer survivors.

    This study utilized a qualitative analysis of child survivors of the Holocaust who were sexually abused during World War II. The research study aimed to give this specific group of survivors a voice and to explore the impact of multiple extreme traumas, the Holocaust and childhood sexual abuse, on the survivors. Twenty-two child survivors of the Holocaust who were sexually abused during the war completed open-ended interviews. The data was qualitatively analyzed according to Tutty, Rothery, and Grinnell's (1996) guidelines. Three major themes were found: issues relating to the sexual abuse trauma, survivors' perceptions of the abuse, and survivors' general perspectives towards life. The identity of the offenders, Jewish or non-Jewish, determined the survivors' feelings towards themselves, the perpetrators, and about the worth of life.

    Cystic kidney disease includes a wide range of hereditary, developmental, and acquired conditions of the kidneys. Some of the inherited causes of cystic kidney disease include autosomal dominant polycystic kidney diseases (caused by mutations in PKD1 or PKD2), autosomal recessive polycystic kidney disease, tuberous sclerosis complex, von Hippel-Lindau disease, oral-facial-digital syndrome type I, and Hadju-Cheney syndrome. Acquired cystic kidney disease has been reported in patients receiving long-term hemodialysis or peritoneal dialysis and in children after liver transplantation. Acute kidney injury can occur in patients with neuroblastoma, usually as a result of thrombotic microangiopathy associated with bone marrow transplantation. End-stage renal disease is described in long-term survivors. However, in this case report, we provide what is to our knowledge the first description of multiple kidney cysts in long-term survivors of stage IV neuroblastoma. None of the 7 patients we describe with neuroblastoma and multiple kidney cysts had a family history of autosomal dominant polycystic kidney disease. Also, all lacked stigmata of tuberous sclerosis complex, von Hippel-Lindau disease, or Hadju-Cheney syndrome. Two patients progressed to end-stage renal disease; in addition, one of them developed an oncocytoid renal cell carcinoma. PMID:27016049

    The eruption of Indonesia's Mount Merapi volcano in 2010 caused extensive environmental degradation. Settlements and hundreds of hectares of farmlands were buried under volcanic ash. Until now, there has been no research on the psychosocial impact of living in an environment damaged by a volcanic eruption. We studied and compared the psychosocial impact of environmental damage on volcano survivors from two subdistricts-Cangkringan and Pakem. Cangkringan survivors affected by the 2010 eruption continue to live in a damaged environment. The Pakem subdistrict was damaged by eruptions of Mt Merapi in the 1990s but there is no recent damage to their environment. The Indonesian-Environmental Distress Scale (I-EDS), a translated revision of the original Environmental Distress Scale (EDS), was used to collect data. Exploratory statistical methods and multivariate linear regression analyses were performed to examine the relative contributions of demographic variables on the psychosocial impact of living in an environment damaged by volcanic eruption. A total of 348 survivors of the Mt Merapi eruption participated in the survey. The mean I-EDS score for Cangkringan district was 15.8 (SD 1.6; range 11.8-19.8) compared to 14.6 (SD 1.3; range 11.8-18.3) for Pakem district (P < 0.001). This result was confirmed by multiple linear regression analysis showing further that older respondents (P < 0.001), unemployed and retired respondents (P = 0.007), and respondents with no formal school education (P = 0.037) had lower I-EDS scores compared to the respective reference groups. Survivors of the Mt Merapi eruption who continue to live in the environment damaged by the 2010 volcanic eruption experience environmental distress. Relevant interventions should target those from low sosioeconomic groups to deal with the distress. PMID:24763946

The number of long-term survivors, off- threatment for at least 5 years, is rising rapidly and is becoming a new population, which needs a special care. It is becoming increasingly important to know how to prevent and treat the physical late effects as well as the psychosocial ones. The oldest among these patients are now in their 40's. How will their old age be like? Are they really cured? The aim of this study is to present a detailed survey of the literature on this topic as well as the authors' personal experience. Several techniques of psychological investigation for this population are highlighted. The semistructured interviews are mostly used for mono-institutional research, while the narrative dialogues are useful for small groups of patients. Questionnaires are usually conducted by epidemiologists for large groups of survivors. Tests are used for specific items such as defense mechanisms, self-esteem, relationships within the family, fear, and panic. The evaluation of the post-traumatic stress disorder is considered and the most important literature data are reported. It is also stressed the need of prevention of any type of psychosocial distress. In conclusion, most of the survivors appear to lead normal adult lives, to have obtained high school degrees, good jobs, and several have families and children. Nevertheless, a small percentage show some psychological or social problems, such as anxiety, depression, fear over the future or over relapse, a second primary, or sterility. The most vulnerable among them are females, people in poor financial conditions, the unemployed and those with poor educations.

  7. Stress and distress.

    I must ask the reader's indulgence for this article's concern with applications of the stress concept, which are distinct from, although related to clinical medicine. It has not been my object to deal with the way physicians have been aided by stress research in the practice of medicine--that information is already widely available. Rather, I have attempted to sketch briefly the history of the stress theory and to demonstrate how this information can help anyone, physician or layman, lead a more complete and satisfying life. The applications of the stress theory have been dealt with at length elsewhere. I believe that we can find within scientifically verified observations the basis of a code of behavior suited to our century. The great laws of nature that regulate the defenses of living beings against stress of any kind are essentially the same at all levels of life, from individual cells to entire complex human organisms and societies. It helps a great deal to understand the fundamental advantages and disadvantages of catatoxic and syntoxic attitudes by studying the biologic basis of self-preservation as reflected in syntoxic and catatoxic chemical mechanisms. When applied to everyday problems, this understanding should lead to choices most likely to provide us the pleasant eustress (from the Greek eu meaning good, as in euphoria) involved in achieving fulfillment and victory, thereby avoiding the self-destructive distress of frustration and failure. So the translation of the laws governing resistance of cells and organs to a code of behavior comes down to three basic precepts: 1. Find your own natural stress level. People differ with regard to the amount and kind of work they consider worth doing to meet the exigencies of daily life and to assure their future security and happiness. In this respect, all of us are influenced by hereditary predispositions and the expectations of our society. Only through planned self-analysis can we establish what we really want

  8. Moral Distress, Workplace Health, and Intrinsic Harm.

    Weber, Elijah

    2016-05-01

    Moral distress is now being recognized as a frequent experience for many health care providers, and there's good evidence that it has a negative impact on the health care work environment. However, contemporary discussions of moral distress have several problems. First, they tend to rely on inadequate characterizations of moral distress. As a result, subsequent investigations regarding the frequency and consequences of moral distress often proceed without a clear understanding of the phenomenon being discussed, and thereby risk substantially misrepresenting the nature, frequency, and possible consequences of moral distress. These discussions also minimize the intrinsically harmful aspects of moral distress. This is a serious omission. Moral distress doesn't just have a negative impact on the health care work environment; it also directly harms the one who experiences it. In this paper, I claim that these problems can be addressed by first clarifying our understanding of moral distress, and then identifying what makes moral distress intrinsically harmful. I begin by identifying three common mistakes that characterizations of moral distress tend to make, and explaining why these mistakes are problematic. Next, I offer an account of moral distress that avoids these mistakes. Then, I defend the claim that moral distress is intrinsically harmful to the subject who experiences it. I conclude by explaining how acknowledging this aspect of moral distress should reshape our discussions about how best to deal with this phenomenon. PMID:26308751

    Hereditary non-polyposis colorectal cancer (HNPCC) represents about 1-3% of all cases of colorectal cancer (CRC). The objectives of the study were to examine motivational factors, expectations and psychosocial functioning in a sample of CRC survivors undergoing genetic testing for HNPCC. A cross-sectional survey of 314 colorectal cancer patients recruited through a population-based colon cancer family registry was conducted. Motivations for genetic testing for hereditary cancer were similar to those of clinic-based samples of CRC patients and included learning of the increased risk to offspring and finding out if additional screening was needed. While age at diagnosis and sex were associated with psychological functioning, significant predictors of post-counseling distress were perceived lower satisfaction with social support, an escape-avoidant coping style and the anticipation of becoming depressed if a mutation was present. Most cancer survivors anticipated disclosing test results to relatives and physicians. Cancer survivors reported several motivations for genetic testing for HNPCC that varied by sex. A subgroup of survivors with lower satisfaction with social support and an escape-avoidant coping style were worried about the potential impact of genetic test results and demonstrated more distress following counseling. Findings have implications for future research and potential support needs during the genetic counseling and testing process. PMID:17892499

    Background Although the association between psychological trauma and early maladaptive schemas (EMS) is well established in the literature, no study to date has examined the relationship of EMS to PTSD and psychopathologies beyond depression and anxiety in a sample of adult survivors of interpersonal trauma. This information may be useful in helping our understanding on how to best treat interpersonal trauma. Objective We set out to investigate the association between EMS and common forms of psychopathology in a sample of women with a history of interpersonal trauma (n=82). We have hypothesised that survivors of interpersonal trauma will present with elevated EMS scores compared to a non-clinical control group (n=78). We have also hypothesised that unique schemas will be associated with unique psychopathological entities and that subgroups of interpersonal trauma survivors would be present in our sample, with subgroups displaying different profiles of schema severity elevations. Method Participants completed measures of trauma, psychopathology, dissociation, self-esteem, and the Young Schema Questionnaire. Results It was found that survivors of interpersonal trauma displayed elevated EMS scores across all 15 schemas compared to controls. Although the pattern of associations between different psychopathological features and schemas appears to be rather complex, schemas in the domains of Disconnection and Impaired Autonomy formed significant associations with all psychopathological features in this study. Conclusions Our findings support the usefulness of cognitive behavioural interventions that target schemas in the domains of Disconnection and Impaired Autonomy in an effort to modify existing core beliefs and decrease subsequent symptomatology in adult survivors of interpersonal trauma. Highlights of the article Interpersonal trauma survivors are distinguished primarily by a generalised elevation of their maladaptive schemas, rather than a unique schema profile

    As of December 6, 2014, Sierra Leone reported 6,317 laboratory-confirmed cases of Ebola virus disease (Ebola), the highest number of reported cases in the current West Africa epidemic. The Sierra Leone Ministry of Health and Sanitation reported that as of December 6, 2014, there were 1,181 persons who had survived and were discharged. Survivors from previous Ebola outbreaks have reported major barriers to resuming normal lives after release from treatment, such as emotional distress, health issues, loss of possessions, and difficulty regaining their livelihoods. In August 2014, a knowledge, attitude, and practice survey regarding the Ebola outbreak in Sierra Leone, administered by a consortium of partners that included the Ministry of Health and Sanitation, UNICEF, CDC, and a local nongovernmental organization, Focus 1000, found that 96% of the general population respondents reported some discriminatory attitude towards persons with suspected or known Ebola. Access to increased psychosocial support, provision of goods, and family and community reunification programs might reduce these barriers. Survivors also have unique potential to contribute to the Ebola response, particularly because survivors might have some immunity to the same virus strain. In previous outbreaks, survivors served as burial team members, contact tracers, and community educators promoting messages that seeking treatment improves the chances for survival and that persons who survived Ebola can help their communities. As caregivers in Ebola treatment units, survivors have encouraged patients to stay hydrated and eat and inspired them to believe that they, too, can survive. Survivors regaining livelihood through participation in the response might offset the stigma associated with Ebola. PMID:25522090

  13. Factors associated with return to work of breast cancer survivors: a systematic review

    PubMed Central

    2014-01-01

    Background The breast cancer survival rate is the highest among all types of cancers, and survivors returning to work after completing treatment is extremely important in regards to economy and rehabilitation. The aim of this systematic review study is to identify the prevalence of breast cancer survivors who return to work (RTW) and the factors associated to RTW. Methods A computer based literature search was carried out. "PubMed, Cochrane Library, Embase, Web of Science, and Science Direct" databases were searched systematically. Our search strategy identified a total of 12,116 papers of which 26 studies met the inclusion criteria and quality assessment. These were original papers published between January 2003 and January 2013. Results The trends in RTW differ among countries for the breast cancer survivors. The time to RTW after successful cancer treatment also varies among the countries and by ethnicity. The prevalence of the RTW varies from 43% to 93% within one year of diagnosis. The prevalence of the RTW for the Netherland is the lowest in the world (43%). The United States survivors showed the highest RTW (93%) within 12 months of the diagnosis. Numerous barriers and facilitators were identified as factors that affect RTW. For instance, socio-demographic factors such as education and ethnicity; treatment oriented factors such as chemotherapy; work related factors such as heavy physical work; disease related factors such as poor health condition and fatigue; and psychological factors such as depression and emotional distress, act as barriers of RTW. In contrast, social, family, employer support, and financial independency emerge as key facilitators in enabling breast cancer survivors to return and continue work. Conclusion Minimising these identified barriers and strengthening these facilitators could further improve the work condition and increase the percentage of RTW among the breast cancer survivors.

    With the aim of accurately assessing the effects of radiation exposure in the Japanese atomic-bomb survivors, the Radiation Effects Research Foundation has, over several decades, conducted studies of the Life Span Study (LSS) cohort, comprising 93 000 atomic-bomb survivors and 27 000 controls. Solid cancer: the recent report on solid cancer incidence found that at age 70 years following exposure at age 30 years, solid cancer rates increase by about 35%  Gy(-1) for men and 58% Gy(-1) for women. Age-at-exposure is an important risk modifier. In the case of lung cancer, cigarette smoking has been found to be an important risk modifier. Radiation has similar effects on first-primary and second-primary cancer risks. Finally, radiation-associated increases in cancer rates appear to persist throughout life. Leukaemia: the recent report on leukaemia mortality suggests that radiation effects on leukaemia mortality persisted for more than 50 years. Moreover, significant dose-response for myelodysplastic syndrome was observed in Nagasaki LSS members even 40-60 years after radiation exposure. Future perspective: given the continuing solid cancer increase in the survivor population, the LSS will likely continue to provide important new information on radiation exposure and solid cancer risks for another 15-20 years, especially for those exposed at a young age.

    2007-04-01

    Caregiving for a spouse who has survived a stroke has multidimensional implications for both the partner and the spousal caregiver. A phenomenological study was conducted to examine the experiences of spousal caregivers for stroke survivors. Eight spouses who met the inclusion criteria participated in the study. van Manen's (1997) approach was used to examine the spousal caregivers' experiences. Data were collected through audiotapes from semistructured interviews. The interviews were transcribed to form textual descriptions of the caregivers' experiences. Six interrelated themes emerged through data analysis: experiencing a profound sense of loss, adjusting to a new relationship with a spouse, taking on new responsibilities, feeling the demands of caregiving, having to depend on the support of others, and maintaining hope and optimism. This study contributes to healthcare providers' understanding and knowledge of spousal caregivers for stroke survivors, and supports the need for continued research in this area. PMID:17477226

    This research examined the effects of group work with survivors of the Wenchuan earthquake. The two groups studied were organised by social workers in a transitional community. One group was composed of older people and the other of women. The research adopted qualitative research methods. Data were collected by focus group meetings and in-depth individual interviews. The 24 research participants were mainly asked to describe their lives before and after joining the groups. The findings indicated that disaster survivors had resilience to loss and trauma and could recover themselves. Group participation facilitated disaster survivors' self recovery and had positive effects on them. Before joining the groups, many members of both groups felt bored and depressed. After joining, they felt better physically and psychologically and enjoyed socialising with each other. Their lives became more meaningful and their social network was broadened and strengthened. The practical and policy implications of the study are noted and further research recommended. It was concluded that group work, in the form of recreational activities, is effective in alleviating disaster survivors' feelings of distress and depression, improving their psychosocial well-being and fostering their self recovery.

    2016-01-01

    Potential negative sequelae for survivors of child sexual abuse is well documented. However, growing evidence suggests that some individuals who actively cope with traumatic events can progress from a negative trajectory toward positive psychological change, often termed posttraumatic growth. Current posttraumatic growth theories may be of limited applicability to developmental considerations involved in child sexual abuse. This explorative study examines posttraumatic growth among adult female survivors of child sexual abuse. In-depth interviews were conducted with six participants who believed they had grown through coping with their abuse. Data was analyzed using interpretative phenomenological analysis. Three superordinate and nine subordinate themes were identified and explored. Some participants reported experiencing growth and distress simultaneously. Theoretical and clinical implications are examined in relation to the study's findings. PMID:26934545

    Objective: To investigate the changes in psychological and social domains associated with treatment in survivors of child sexual abuse. Method: Participants from four centers were assessed at baseline and were followed up after six and 12 months. The battery covered posttraumatic and general distress symptoms, attachment, coping styles, self-worth, and social support. Results: The estimated prevalence of Posttraumatic Stress Disorder (PTSD) was 78% at baseline; this rate declined to 40% after one year. There were no differences in outcome measures across the different centers or between the individual and group treatments. Half of the PTSD variation at 12 months was explained by four factors: education, avoidance attachment, emotional coping, and social support. Conclusion: The findings in this study indicated a substantial reduction in mental health problems in survivors following 12 months of treatment and identified personality and social factors important for recovery.

    1992-03-01

    The optimum level of positive end expiratory pressure (PEEP) was determined in 16 infants with respiratory distress syndrome (median gestational age 29 weeks, median postnatal age 1 day) and in 16 infants with chronic respiratory distress (median gestational age 25 weeks, median postnatal age 15 days). All infants were studied at a PEEP sequence of 3, 0, 3, 6, and 3 cm H2O, all other ventilator parameters being kept constant. Each PEEP level was maintained for 20 minutes and at the end of each period arterial blood gas was checked. During acute respiratory distress syndrome there were no significant changes in oxygenation but arterial carbon dioxide tension (PaCO2) significantly decreased from a mean of 4.93 kPa at 3 cm H2O to 4.40 kPa at 0 cm H2O and increased to a mean of 5.87 kPa at 6 cm H2O. In the infants with chronic respiratory distress, oxygenation fell from a mean of 8.66 kPa at 3 cm H2O to 6.40 kPa at 0 cm H2O and improved at 6 cm H2O to a mean of 10.50 kPa. There were no significant changes in PaCO2. We conclude that addition of PEEP, up to 6 cm H2O, may be useful even after the first week of life. High levels of PEEP, however, have previously been reported, in certain infants, to result in circulatory disturbance. It is therefore important to assess the use of 6 cm H2O PEEP in a controlled study of longer term clinical outcome.

    The aim of this paper is to understand the effects of childhood sexual abuse on a survivor’s later life. For understanding and treating the emotional distress and interpersonal problems resulting from childhood sexual abuse, attachment theory provides a valuable framework. When this framework is combined with family systems theory, it can help therapists understand the family context where sexual abuse occurs and how this affects health and functioning throughout the lifespan. Case examples of female adult sexual abuse survivors are also explored, with insight from the intersection of systems and attachment theories. PMID:24443623

    2008-06-01

    Effects of socioeconomic factors and cancer survivors' worries on their quality of life (QOL) were investigated. In 2002, Japanese national survey was performed to assess distress among cancer patients using a semi-structured questionnaire (http://www.scchr.jp/yorozu/pdf/taiken_koe_eng.pdf). We investigated relationships between patients' distress and their QOL measured by European Organization for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) and Functional Assessment of Chronic Illness Therapy--12-item Spiritual Well-Being Scale (FACIT-Sp), using a covariance structure analysis and multivariate regression analysis. A total of 130 outpatients (male: 42%; average age: 59 years; performance status rating 0-2:89%; breast/lung/gastrointestinal cancer: 38/22/21%) answered the questionnaires. A covariance structure analysis extracted latent variables, which were named socioeconomic distress and cancer worries, using a model that sufficiently represented the observed data (Goodness of fit index = 0.833). Regression analysis demonstrated that higher family income significantly correlated with better Global health status/QOL (p = 0.003) but that losing a job negatively correlated with all of the scales on functioning in the QLQ-C30 (p < 0.05) and spiritual well-being (p < 0.05). Patients' QOL was also affected by physical worries and spiritual issues in terms of emotional, cognitive, and social functioning. In conclusion, cancer survivors' QOL was doubly affected by socioeconomic distress and cancer worries. In the former, lower family income and losing employment by experiencing cancer had a negative impact on patients' QOL. As to the latter, physical worries and spiritual issues also affected patients' QOL. PMID:17972358

  17. Distressing near-death experiences.

    PubMed

    Greyson, B; Bush, N E

    1992-02-01

    Most reported near-death experiences include profound feelings of peace, joy, and cosmic unity. Less familiar are the reports following close brushes with death of experiences that are partially or entirely unpleasant, frightening, or frankly hellish. While little is known about the antecedents or aftereffects of these distressing experiences, there appear to be three distinct types, involving (1) phenomenology similar to peaceful near-death experiences but interpreted as unpleasant, (2) a sense of nonexistence or eternal void, or (3) graphic hellish landscapes and entities. While the first type may eventually convert to a typical peaceful experience, the relationship of all three types to prototypical near-death experiences merits further study. The effect of the distressing experience in the lives of individuals deserves exploration, as the psychological impact may be profound and long-lasting.

    A high rate of ENT doctors were murdered by nasal disordered patients in China recently. It is obviously important and urgent to find out whether there is any potential relationship between nasal diseases (ND) and psychological distress that might contribute to violent behavior. For this purpose, we carried out this literature review. There is a complex relationship between ND and psychiatric distress, which is mainly considered as a bidirectional causal relationship with other controversy opinions. However, most of the previous studies were found to be focused on allergic rhinitis and chronic rhinosinusitis, while reports about other ND were rare. Further study is still needed to uncover the secret aspects in this field, and more attentions need to be paid to other ND. PMID:26095351

    BACKGROUND Legislation to establish a Truth and Reconciliation Commission (TRC) was passed soon after election of South Africa’s first democratic government. Discourse around the TRC focused on the importance of bearing witness to the past, and on the healing powers of forgiveness. However, there was also a concern that individuals with TRC relevant experience would simply be re-traumatized by participation in the process. To date, there has been little empirical data for either hypothesis. METHODS A nationally representative survey of the South African population (n=4351) was undertaken 6 to 8 years after the TRC process began. Information about subjects’ exposure to and participation in the TRC was collected, and views about the testimony of survivors and perpetrators were assessed. To determine the predictors of distress, anger, and forgiveness, linear regressions were undertaken with inclusion of demographic variables, exposure to TRC variables, and attitudes to the TRC. RESULTS Distress was significantly associated with specific demographic factors (female gender, less education), with having a TRC related experience to share, and with negative perceptions of the TRC (a negative view of survivors’ testimony). Anger had similar associations but was also predicted by lower age. Forgiveness was associated with age and education, with being Coloured, and with having a positive view of perpetrator’s testimony, while it was inversely associated with having a TRC experience to share. Distress and anger correlated inversely with forgiveness. Perceptions of the TRC were moderately positive irrespective of many demographic variables (race, education, age). CONCLUSION In this cross-sectional study, causal relationships are difficult to ascertain. Nevertheless, relationships between increased distress/anger, having a TRC relevant experience to share, and negative perceptions of the TRC, support a view that bearing testimony is not necessarily helpful to survivors

    Background Prostate cancer survivors with a rising prostate specific antigen (PSA) level have few treatment options, experience a heightened state of uncertainty about their disease trajectory that might include the possibility of cancer metastasis and death, and often experience elevated levels of distress as they have to deal with a disease they thought they had conquered. Guided by self-regulation theory, the present study examined the cognitive and affective processes involved in shared decision making between physician and patients who experience a rising PSA after definitive treatment for prostate cancer. Methods In-depth interviews were conducted with 34 prostate cancer survivors who had been diagnosed with a rising PSA (i.e., biochemical failure) within the past 12 months. Survivors were asked about their experiences and affective responses after being diagnosed with a rising PSA and while weighing potential treatment options. In addition, patients were asked about their decision-making process for the initial prostate cancer treatment. Results Compared to the initial diagnosis, survivors with a rising PSA reported increased negative affect following their diagnosis, concern about the treatability of their disease, increased planning and health behavior change, heightened levels of worry preceding doctor’s appointments (especially prior to the discussion of PSA testing results), and a strong reliance on physicians’ treatment recommendations. Conclusions Prostate cancer survivors’ decision-making processes for the treatment of a rising PSA are markedly different from those of the initial diagnosis of prostate cancer. Because patients experience heightened distress and rely more heavily on their physicians’ recommendations with a rising PSA, interactions with the health care provider provide an excellent opportunity to address and assist patients with managing the uncertainty and distress inherent with rising PSA levels.

    Previous reports on survivors of Reye's syndrome have indicated a high proportion of significant neurological and intellectual sequelae. However, increasingly sophisticated monitoring and therapeutic techniques have diminished both the mortality and morbidity of this disease. Our present study documented the relatively good intellectual and neurological prognosis for recent survivors of Reye's at our institution and explored the emotional impact of this illness on survivor's families. The significant emotional problems of the children and their families were in striking contrast to the relatively good intellectual and academic recovery. Nine of the 16 survivors showed emotional disruption (primarily somatic complaints, anxiety, and depression). Fourteen of 16 mothers interviewed continued to suffer from anxiety, depression, and overprotective behavior as long as 5 years after their child's illness. In many respects, the parents endured more prolonged and profound suffering than did the children. These findings have implications for the delivery of follow-up care to families of survivors.

    Twelve per cent of all infants with respiratory distress admitted to our neonatal intensive-care unit from November, 1973 to April, 1974, were born after elective intervention (15 cesarean sections and four vaginal inductions). All were white and 18/19 were private compared to yearly admissions of white (56 per cent) and private (57 per cent). Eighteen of 19 were admitted from the region via the transport service. Mean birth weight was 2.69 kilograms, with 18 infants over 2 kilograms. Pediatric gestational age from a physical and neurological evaluation ranged from 32 to 39 weeks (mean 36.2 weeks) in contrast to obstetric dating which ranged from 38 to 44 weeks (mean 39 weeks). The obstetric dating was 3 or more weeks greater than the pediatric age in 11 infants. Pulmonary disease included transient tachypnea (5) and respiratory distress syndrome (14). No prior documentation of pulmonary maturity had been obtained in any of these infants. Mean hospitalization was 23 days (range 1 to 140), with estimated costs of $3,421 per baby. Two infants died. Respiratory distress following elective delivery remains a potent source of on-going perinatal morbidity. Regional programs must direct increased educational efforts to eliminate this preventable disease.

    Stroke is an unpredictable and life-altering medical occurrence that causes immediate change in survivors' relationships. This study unearthed dialectical tensions expressed by spouses of stroke survivors and examined how those dialectical tensions compare to those experienced by stroke survivors themselves. Sixteen spouses of stroke survivors participated in interviews, and four tensions ultimately emerged: self-orientation-partner-orientation, realism-idealism, uncertainty-acceptance, and emotional release-emotional reservation. Three dialectical tensions (i.e., uncertainty-acceptance, realism-idealism, self-orientation-partner-orientation) were similar to those communicated by stroke survivors. Recognizing dialectical tensions experienced and shared can open communication lines and ultimately improve the health of individuals and their relationships. PMID:20512714

    Background Hemorrhagic fever with renal syndrome (HFRS) has become an important public health concern because of the high incidence and mortality rates, and limited treatment and vaccination. Until now, clinical studies on characteristics and outcomes in critical patients with HFRS have been limited. The aim of this study was to observe the clinical characteristics and cumulative proportions surviving and explore the predictive effects and risk factors for prognosis. Methods A detailed retrospective analysis of clinical records for critical HFRS patients was conducted. The patients enrolled were treated in the centre for infectious diseases, Tangdu Hospital, between January 2008 and August 2012. The clinical characteristics between the survivors and non-survivors were compared by Student’s t-test or Chi-square test. The risk clinical factors for prognosis were explored by logistic regression analysis. The predictive effects of prognosis in clinical and laboratory parameters were analyzed by receiver operating characteristic (ROC) curves. The cumulative proportions surviving at certain intervals in the critical patients were observed by Kaplan-Meier survival analysis. Results Of the 75 patients enrolled, the cumulative proportion surviving was 70.7% at the second week interval, with a 28-day mortality rate of 36.3%. The non-survivors tended to have higher frequencies of agitation, dyspnea, conjunctival hemorrhage, coma, cardiac failure, acute respiratory distress syndrome (ARDS) and encephalopathy (P < .05). ARDS, conjunctival hemorrhage and coma were risk factors for death in the critical patients with HFRS. The non-survivors were found to have lower serum creatinine (Scr) levels (P < .001) and higher incidences of prolonged prothrombin time (PT) (P = .006), activated partial thromboplastin time (APTT) (P = .003) and elevated white blood cells (WBC) levels (P = .005), and the laboratory parameters mentioned above reached statistical

    Given the limited scientific knowledge about dietary factors that affect cancer recurrence, dietary guidelines for cancer survivors are similar to general recommendations on healthy eating. This study explored the patterns of and motivation for, dietary changes among cancer patients. We conducted in-person interviews with 143 cancer survivors who were chosen from a mail survey on complementary and alternative medicine among cancer patients. We applied qualitative analysis using the software package NUD*IST to sort and code the transcribed interviews. The majority of dietary changes reported by 69 cancer patients agreed with current nutritional recommendations, such as decreasing meat and fat intake and increasing the consumption of vegetables and fruits. However, many diet changers also reported the intake of herbal and vitamin supplements, many with unproven effects. The major themes for changing diet were hopes that nutrition would increase well-being, maintain health and prevent cancer recurrence and beliefs that foods that cause or prevent cancer should be avoided and increased, respectively. Many cancer patients use non-scientific reasons when deciding on dietary changes and supplement use. Increasing communication with health care providers may prevent the use of extreme diets, unproven and possibly harmful supplements and reduce exaggerated hopes related to the benefits of a particular dietary regimen.

    Introduction Little is known about the impact of childhood cancer on the personal income of survivors. We compared income between survivors and siblings, and determined factors associated with income. Methods As part of the Swiss Childhood Cancer Survivor Study (SCCSS), a questionnaire was sent to survivors, aged ≥18 years, registered in the Swiss Childhood Cancer Registry (SCCR), diagnosed at age <21 years, who had survived ≥5 years after diagnosis of the primary tumor. Siblings were used as a comparison group. We asked questions about education, profession and income and retrieved clinical data from the SCCR. We used multivariable logistic regression to identify characteristics associated with income. Results We analyzed data from 1’506 survivors and 598 siblings. Survivors were less likely than siblings to have a high monthly income (>4’500 CHF), even after we adjusted for socio-demographic and educational factors (OR = 0.46, p<0.001). Older age, male sex, personal and parental education, and number of working hours were associated with high income. Survivors of leukemia (OR = 0.40, p<0.001), lymphoma (OR = 0.63, p = 0.040), CNS tumors (OR = 0.22, p<0.001), bone tumors (OR = 0.24, p = 0.003) had a lower income than siblings. Survivors who had cranial irradiation, had a lower income than survivors who had no cranial irradiation (OR = 0.48, p = 0.006). Discussion Even after adjusting for socio-demographic characteristics, education and working hours, survivors of various diagnostic groups have lower incomes than siblings. Further research needs to identify the underlying causes. PMID:27213682

    Distressing somatic symptoms are ubiquitous both in mental disorders and medical diseases. From a psychometric perspective, the structure of somatic symptom distress is unclear, and little is known about the strengths of associations to related constructs, such as health anxiety and somatosensory amplification. To clarify the structure of somatic symptom distress and to explore associations to health anxiety, somatosensory amplification, and functional somatic syndromes, data sets of 2 samples of college students from Germany (N = 1,520) and Switzerland (N = 3,053) were investigated with confirmatory factor analysis with robust estimation. A bifactor model (with 1 general and 4 orthogonal specific symptom factors-gastrointestinal, fatigue, cardio-pulmonary, and pain symptoms) revealed the best model fit. Medium-sized associations were found among latent factors of general somatic symptom distress, health anxiety, and depression. First evidence for the construct validity of the latent variables within the proposed bifactor structure was gained by observing (a) strong associations between the general somatic symptom distress factor and somatosensory amplification and (b) significant associations between both the general somatic symptom factor as well as the symptom-specific factors with functional somatic syndromes. The results offer a theoretically and psychometrically plausible model for the structure of somatic symptom distress and suggest a distinction between cognitive-affective and sensory aspects of symptom perception. The findings are compatible with current cognitive psychological and neuropsychological approaches to symptom perception and imply that somatic symptom distress is a multidimensional phenomenon that is both strongly linked to but also clearly separable from related constructs.

    The psychological impact of an unfavorable genetic test result for counselees at risk for hereditary cancer seems to be limited: only 10-20 % of counselees have psychological problems after testing positive for a known familial mutation. The objective of this study was to find prognostic factors that can predict which counselees are most likely to develop psychological problems after presymptomatic genetic testing. Counselees with a 50 % risk of BRCA1/2 or Lynch syndrome completed questionnaires at three time-points: after receiving a written invitation for a genetic counseling intake (T1), 2-3 days after receiving their DNA test result (T2), and 4-6 weeks later (T3). The psychological impact of the genetic test result was examined shortly and 4-6 weeks after learning their test result. Subsequently, the influence of various potentially prognostic factors on psychological impact were examined in the whole group. Data from 165 counselees were analyzed. Counselees with an unfavorable outcome did not have more emotional distress, but showed significantly more cancer worries 4-6 weeks after learning their test result. Prognostic factors for cancer worries after genetic testing were pre-existing cancer worries, being single, a high risk perception of getting cancer, and an unfavorable test result. Emotional distress was best predicted by pre-existing cancer worries and pre-existing emotional distress. The psychological impact of an unfavorable genetic test result appears considerable if it is measured as "worries about cancer." Genetic counselors should provide additional guidance to counselees with many cancer worries, emotional distress, a high risk perception or a weak social network.

    This prospective study examined the pathways by which religious involvement affected the post-disaster psychological functioning of women who survived Hurricanes Katrina and Rita. The participants were 386 low-income, predominantly Black, single mothers. The women were enrolled in the study before the hurricane, providing a rare opportunity to document changes in mental health from before to after the storm, and to assess the protective role of religious involvement over time. Results of structural equation modeling indicated that, controlling for level of exposure to the hurricanes, pre-disaster physical health, age, and number of children, pre-disaster religiousness predicted higher levels of post-disaster (1) social resources and (2) optimism and sense of purpose. The latter, but not the former, was associated with better post-disaster psychological outcome. Mediation analysis confirmed the mediating role of optimism and sense of purpose.

    Summary Screening for distress in cancer patients is recommended by the National Comprehensive Cancer Network, and a Distress Thermometer has previously been developed and empirically-validated for this purpose. The present study sought to determine the rates and predictors of distress in a sample of patients being seen in a multidisciplinary lung cancer clinic. Consecutive patients (N = 333) were recruited from an outpatient multidisciplinary lung cancer clinic to complete the Distress Thermometer, an associated Problem Symptom List, and two questions about interest in receiving help for symptoms. Over half (61.6%) of patients reported distress at a clinically significant level, and 22.5% of patients indicated interest in receiving help with their distress and/or symptoms. Problems in the areas of family relationships, emotional functioning, lack of information about diagnosis/treatment, physical functioning, and cognitive functioning were associated with higher reports
