    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

    To evaluate prevalence, severity, and co-occurrence of and risk factors for depression, anxiety, and posttraumatic stress disorder symptoms over the first year after acute respiratory distress syndrome. Prospective longitudinal cohort study. Forty-one Acute Respiratory Distress Syndrome Network hospitals across the United States. Six hundred ninety-eight acute respiratory distress syndrome survivors. None. Psychiatric symptoms were evaluated by using the Hospital Anxiety and Depression Scale and Impact of Event Scale-Revised at 6 and 12 months. Adjusted prevalence ratios for substantial symptoms (binary outcome) and severity scores were calculated by using Poisson and linear regression, respectively. During 12 months, a total of 416 of 629 patients (66%) with at least one psychiatric outcome measure had substantial symptoms in at least one domain. There was a high and almost identical prevalence of substantial symptoms (36%, 42%, and 24% for depression, anxiety, and posttraumatic stress disorder) at 6 and 12 months. The most common pattern of co-occurrence was having symptoms of all three psychiatric domains simultaneously. Younger age, female sex, unemployment, alcohol misuse, and greater opioid use in the ICU were significantly associated with psychiatric symptoms, whereas greater severity of illness and ICU length of stay were not associated. Psychiatric symptoms occurred in two thirds of acute respiratory distress syndrome survivors with frequent co-occurrence. Sociodemographic characteristics and in-ICU opioid administration, rather than traditional measures of critical illness severity, should be considered in identifying the patients at highest risk for psychiatric symptoms during recovery. Given high co-occurrence, acute respiratory distress syndrome survivors should be simultaneously evaluated for a full spectrum of psychiatric sequelae to maximize recovery.

    Little is known about the long-term outcomes and costs of survivors of acute respiratory distress syndrome (ARDS). To describe functional and quality of life outcomes, health care use, and costs of survivors of ARDS 2 yr after intensive care unit (ICU) discharge. We recruited a cohort of ARDS survivors from four academic tertiary care ICUs in Toronto, Canada, and prospectively monitored them from ICU admission to 2 yr after ICU discharge. Clinical and functional outcomes, health care use, and direct medical costs. Eighty-five percent of patients with ARDS discharged from the ICU survived to 2 yr; overall 2-yr mortality was 49%. At 2 yr, survivors continued to have exercise limitation although 65% had returned to work. There was no statistically significant improvement in health-related quality of life as measured by Short-Form General Health Survey between 1 and 2 yr, although there was a trend toward better physical role at 2 yr (p = 0.0586). Apart from emotional role and mental health, all other domains remained below that of the normal population. From ICU admission to 2 yr after ICU discharge, the largest portion of health care costs for a survivor of ARDS was the initial hospital stay, with ICU costs accounting for 76% of these costs. After the initial hospital stay, health care costs were related to hospital readmissions and inpatient rehabilitation. Survivors of ARDS continued to have functional impairment and compromised health-related quality of life 2 yr after discharge from the ICU. Health care use and costs after the initial hospitalization were driven by hospital readmissions and inpatient rehabilitation.

    To longitudinally evaluate the association of post-ICU muscle weakness and associated trajectories of weakness over time with 5-year survival. Longitudinal prospective cohort study over 5 years of follow-up. Thirteen ICUs in four hospitals in Baltimore, MD. One hundred fifty-six acute respiratory distress syndrome survivors. None. Strength was evaluated with standardized manual muscle testing using the Medical Research Council sum score (range, 0-60; higher is better), with post-ICU weakness defined as sum score less than 48. Muscle strength was assessed at hospital discharge and at 3, 6, 12, 24, 36, and 48 months after acute respiratory distress syndrome. At discharge, 38% of patients had muscle weakness. Every one point increase in sum score at discharge was associated with improved survival (hazard ratio [95% CI], 0.96 [0.94-0.98]), with similar findings longitudinally (0.95 [0.93-0.98]). Having weakness at discharge was associated with worse 5-year survival (1.75 [1.01-3.03]), but the association was attenuated (1.54 [0.82-2.89]) when evaluated longitudinally over follow-up. Persisting and resolving trajectories of muscle weakness, occurring in 50% of patients during follow-up, were associated with worse survival (3.01 [1.12-8.04]; and 3.14 [1.40-7.03], respectively) compared to a trajectory of maintaining no muscle weakness. At hospital discharge, greater than one third of acute respiratory distress syndrome survivors had muscle weakness. Greater strength at discharge and throughout follow-up was associated with improved 5-year survival. In patients with post-ICU weakness, both persisting and resolving trajectories were commonly experienced and associated with worse survival during follow-up.

    With improving short-term mortality in acute respiratory distress syndrome (ARDS), understanding and improving quality of life (QOL) outcomes in ARDS survivors is a clinical and research priority. We sought to identify variables associated with QOL, as measured by the EQ-5D health utility score, after ARDS using contemporary data science methods. Analysis of prospectively acquired baseline variables and 6-month EQ-5D health utility scores for adults with ARDS enrolled in the ARDS Network Long-Term Outcomes Study (ALTOS). Penalised regression identified predictors of health utility, with results validated using 10-fold cross-validation. Among 616 ARDS survivors, several predictors were associated with 6-month EQ-5D utility scores, including two lifestyle factors. Specifically, older age, female sex, Hispanic/Latino ethnicity, current smoking and higher body mass index were associated with lower EQ-5D utilities, while living at home without assistance at baseline and AIDS were associated with higher EQ-5D utilities in ARDS survivors. No acute illness variables were associated with EQ-5D utility. Acute illness variables do not appear to be associated with postdischarge QOL among ARDS survivors. Functional independence and lifestyle factors, such as obesity and tobacco smoking, were associated with worse QOL. Future analyses of postdischarge health utility among ARDS survivors should incorporate measures of demographics and functional independence at baseline.

    Nearly 60% of patients who are intubated in intensive care units (ICUs) experience dysphagia after extubation, and approximately 50% of them aspirate. Little is known about dysphagia recovery time after patients are discharged from the hospital. To determine factors associated with recovery from dysphagia symptoms after hospital discharge for acute respiratory distress syndrome (ARDS) survivors who received oral intubation with mechanical ventilation. This is a prospective, 5-year longitudinal cohort study involving 13 ICUs at four teaching hospitals in Baltimore, Maryland. The Sydney Swallowing Questionnaire (SSQ), a 17-item visual analog scale (range, 0-1,700), was used to quantify patient-perceived dysphagia symptoms at hospital discharge, and at 3, 6, 12, 24, 36, 48, and 60 months after ARDS. An SSQ score greater than or equal to 200 was used to indicate clinically important dysphagia symptoms at the time of hospital discharge. Recovery was defined as an SSQ score less than 200, with a decrease from hospital discharge greater than or equal to 119, the reliable change index for SSQ score. Fine and Gray proportional subdistribution hazards regression analysis was used to evaluate patient and ICU variables associated with time to recovery accounting for the competing risk of death. Thirty-seven (32%) of 115 patients had an SSQ score greater than or equal to 200 at hospital discharge; 3 died before recovery. All 34 remaining survivors recovered from dysphagia symptoms by 5-year follow-up, 7 (23%) after 6 months. ICU length of stay was independently associated with time to recovery, with a hazard ratio (95% confidence interval) of 0.96 (0.93-1.00) per day. One-third of orally intubated ARDS survivors have dysphagia symptoms that persist beyond hospital discharge. Patients with a longer ICU length of stay have slower recovery from dysphagia symptoms and should be carefully considered for swallowing assessment to help prevent complications related to dysphagia.

    Background and Aims: This study aims to evaluate the sleep quality, architecture, sleep-related quality of life, and sleep-disordered breathing (SDB) in acute respiratory distress syndrome (ARDS) survivors early after discharge. Materials and Methods: In this prospective, observational study, consecutive patients with ARDS discharged from the Intensive Care Unit (ICU) underwent evaluation with Epworth sleepiness scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Functional Outcomes of Sleep Questionnaire (FOSQ), and overnight polysomnography. Patients having one or more of the following characteristics were classified as having abnormal sleep: ESS>10, PSQI>5, FOSQ <17.9, apnea–hypopnea index (AHI) ≥5, or AHI during rapid eye movement (REM) sleep ≥5. Results: Twenty patients (median interquartile range [IQR] age of 24 [22–28] years, 11 [55%] females) were included in the study. Acute febrile illness of unknown etiology with multi-organ dysfunction syndrome was the most common underlying etiology for ARDS. The median (IQR) PaO2/FiO2 ratio and APACHE II scores on admission were 176 (151–191.5) and 14 (14–16), respectively. The median (IQR) duration of stay in the ICU was 10 days (7.3–19.5). The overall sleep efficiency (median [IQR], 54% [32.3–65.4%]) was poor. None of the patients had ESS>10, seven (35%) had global PSQI>5 and one had FOSQ <17.9. Ten (50%) patients had at least one characteristic that suggested abnormal sleep (4 insomnia, 2 central sleep apnea, 1 obstructive sleep apnea, 1 REM-SDB, and 2 with a high PSQI, but no specific sleep abnormality). Conclusions: Sleep disturbances are common in ARDS survivors early after discharge from the ICU. PMID:27390455

    Sleep disruption is well recognized in the Intensive Care Unit. Poor sleep quality likely continues following discharge from hospital in several patients and becomes a chronic disorder in some. The aim of this study was to describe the etiology of chronic sleep complaints in survivors of ARDS. Seven ARDS survivors with no previous sleep complaints who reported difficulty sleeping 6 months or more following discharge from hospital were evaluated. Sleep quality was assessed subjectively with a sleep history and the Insomnia Severity Index and objectively with polysomnography. Daytime sleepiness was assessed with the Epworth Sleepiness Scale. A chronic sleep disorder was identified in each patient who reported difficulty sleeping. The primary sleep disorder was chronic conditioned insomnia (5 patients), parasomnia (1 patient) and obstructive sleep apnea (1 patient). In addition, 4 patients had periodic leg movements, which was of uncertain clinical significance. Chronic sleep disorders, which originate during the acute illness, are present in some ARDS survivors several months after discharge from hospital. If unrecognized, lack of treatment may contribute to impaired quality of life and incomplete rehabilitation from their critical illness.

    Suicide bereavement is frequently related to clinically significant psychological distress and affected by stigma. This study was designed to evaluate the relationship between psychological distress by psychopathological domains and stigma, in a sample of individuals bereaved by suicide (suicide survivors). The data were collected between January 2012 and December 2014 and included information on sociodemographic variables (gender, age, marital status and education level) and responses to the Stigma of Suicide Survivor scale (STOSSS) and the Brief Symptom Inventory (BSI). One hundred and fifty-five suicide survivors completed the evaluation and were included in the study. Levels of psychological distress in suicide survivors, as measured by BSI, were positively related to levels of perceived stigma toward suicide survivors, as measured by STOSSS. The association was not affected by age and gender, or by marital status, education level, days from suicide or a personal history of suicide attempt. Participants with higher scores on almost all subscales of the BSI, particularly the interpersonal sensitivity and paranoid ideation subscales, reported the highest levels of perceived stigma toward suicide survivors. Levels of distress in subjects bereaved by the suicide of a relative or friend were positively associated with levels of perceived stigma toward suicide survivors. Specific interventions dedicated to the bereavement of suicide survivors might help to alleviate not only psychological distress but also stigma towards loss by suicide.

    Transitions to outpatient care are crucial after critical illness, but the documentation practices in discharge documents after critical illness are unknown. To characterize the rates of documentation of various features of critical illness in discharge documents of patients diagnosed with acute respiratory distress syndrome (ARDS) during their hospital stay. We used natural language processing tools to build a keyword-based classifier that categorizes discharge documents by presence of terms from four groups of keywords related to critical illness. We used a multivariable modified Poisson regression model to infer patient- and hospital-level characteristics associated with documentation of relevant keywords. A manual chart review was used to validate the accuracy of the keyword-based classifier, and to assess for ARDS documentation during the hospital stay. Of 815 discharge documents, ARDS was identified in only 111 (13%). Mechanical ventilation was identified in 770 (92%) and intensive care unit (ICU) admission in 693 (83%) of discharge documents. Symptoms or recommendations related to post-intensive care syndrome were included in 306 (38%) of discharge documents. Patient age (older; relative risk [RR] = 0.97/yr, 95% confidence interval [CI] = 0.96-0.98) and higher PaO2:FiO2 (decreasing illness severity; RR = 0.96/10-unit increment, 95% CI = 0.93-0.98) were associated with decreased documentation of ARDS. Being discharged from a surgical (RR = 0.33, 95% CI = 0.22-0.50) compared with a medicine service was also associated with decreased rates of ARDS documentation. The manual chart review revealed 98% concordance between ARDS documentation in the discharge summary and during the hospital stay. Accuracy of the document classifier was 100% for ARDS and mechanical ventilation, 98% for ICU admission, and 95% for symptoms of post-intensive care syndrome. In the discharge documents of survivors of ARDS, ARDS itself is rarely mentioned, but

    Background: Little is known about the long-term outcomes of severe acute respiratory distress syndrome (ARDS) patients requiring extracorporeal membrane oxygenation (ECMO). This study aimed to investigate the 1-year outcomes of these patients or patients receiving mechanical ventilation (MV) and compare their health-related quality of life (HRQoL) to the general population. Methods: Severe ARDS survivors admitted to two ICUs in China between January 2012 and January 2014 were enrolled. Of the severe ARDS survivors enrolled, 1-year postdischarge, HRQoL assessment using the Short-Form 36 (SF-36) and EuroQol questionnaire dimensions, 6-min walking distance, chest computed tomography scan, pulmonary function, and arterial blood gas analysis were compared for ARDS patients with or without ECMO. Results: ARDS patients receiving ECMO had a significantly higher Acute Physiology and Chronic Health Evaluation II score (30.3 ± 6.7 vs. 26.5 ± 7.3, P = 0.036), lung injury score (3.3 ± 0.4 vs. 2.8 ± 0.5, P = 0.000), Sequential Organ Failure Assessment score (10.8 ± 3.5 vs. 7.9 ± 3.1, P = 0.000), lower PaO2/FiO2 ratio ([mmHg, 1 mmHg = 0.133 kPa], 68.3 ± 16.1 vs. 84.8 ± 16.5, P = 0.000), and increased extrapulmonary organ failure (2 [1, 3] vs. 1 [1, 1], P = 0.025) compared with patients not receiving ECMO. ECMO and non-ECMO survivors showed similar pulmonary function, morphological abnormalities, resting arterial blood gas values, and 6-min walking distance. Mild pulmonary dysfunction and abnormal morphology were observed in a few survivors. In addition, ECMO and non-ECMO survivors showed a similar quality of life. ECMO survivors showed lower SF-36 physical functioning and role-physical domain scores (minimum clinically significant difference at least 5 points), and non-ECMO survivors had similar outcome. Conclusions: One-year posthospital discharge, severe ARDS survivors receiving ECMO or MV demonstrated comparable outcomes. Compared with the general population, ARDS

    Delayed return to work is common after acute respiratory distress syndrome (ARDS), but has undergone little detailed evaluation. We examined factors associated with the timing of return to work after ARDS, along with lost earnings and shifts in healthcare coverage. Five-year, multisite prospective, longitudinal cohort study of 138 2-year ARDS survivors hospitalised between 2004 and 2007. Employment and healthcare coverage were collected via structured interview. Predictors of time to return to work were evaluated using Fine and Grey regression analysis. Lost earnings were estimated using Bureau of Labor Statistics data. Sixty-seven (49%) of the 138 2-year survivors were employed prior to ARDS. Among 64 5-year survivors, 20 (31%) never returned to work across 5-year follow-up. Predictors of delayed return to work (HR (95% CI)) included baseline Charlson Comorbidity Index (0.77 (0.59 to 0.99) per point; p=0.04), mechanical ventilation duration (0.67 (0.55 to 0.82) per day up to 5 days; p<0.001) and discharge to a healthcare facility (0.49 (0.26 to 0.93); p=0.03). Forty-nine of 64 (77%) 5-year survivors incurred lost earnings, with average (SD) losses ranging from US$38 354 (21,533) to US$43 510 (25,753) per person per year. Jobless, non-retired survivors experienced a 33% decrease in private health insurance and concomitant 37% rise in government-funded coverage. Across 5-year follow-up, nearly one-third of previously employed ARDS survivors never returned to work. Delayed return to work was associated with patient-related and intensive care unit/hospital-related factors, substantial lost earnings and a marked rise in government-funded healthcare coverage. These important consequences emphasise the need to design and evaluate vocation-based interventions to assist ARDS survivors return to work. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To evaluate the time-varying relationship of annual physical, psychiatric, and quality of life status with subsequent inpatient healthcare resource use and estimated costs. Five-year longitudinal cohort study. Thirteen ICUs at four teaching hospitals. One hundred thirty-eight patients surviving greater than or equal to 2 years after acute respiratory distress syndrome. None. Postdischarge inpatient resource use data (e.g., hospitalizations, skilled nursing, and rehabilitation facility stays) were collected via a retrospective structured interview at 2 years, with prospective collection every 4 months thereafter, until 5 years postacute respiratory distress syndrome. Adjusted odds ratios for hospitalization and relative medians for estimated episode of care costs were calculated using marginal longitudinal two-part regression. The median (interquartile range) number of inpatient admission hospitalizations was 4 (2-8), with 114 patients (83%) reporting greater than or equal to one hospital readmission. The median (interquartile range) estimated total inpatient postdischarge costs over 5 years were $58,500 ($19,700-157,800; 90th percentile, $328,083). Better annual physical and quality of life status, but not psychiatric status, were associated with fewer subsequent hospitalizations and lower follow-up costs. For example, greater grip strength (per 6 kg) had an odds ratio (95% CI) of 0.85 (0.73-1.00) for inpatient admission, with 23% lower relative median costs, 0.77 (0.69-0.87). In a multisite cohort of long-term acute respiratory distress syndrome survivors, better annual physical and quality of life status, but not psychiatric status, were associated with fewer hospitalizations and lower healthcare costs.

    Purpose To estimate the prevalence of emotional distress in a large cohort of adult survivors of childhood cancer and evaluate the interrelationship of risk factors including cancer-related late effects. Methods 1,863 adult survivors of childhood cancer, median age of 32 years at follow-up, completed comprehensive medical evaluations. Clinically relevant emotional distress was assessed using the Brief Symptom Inventory-18 and was defined as T-scores ≥63. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariable logistic regression models to identify risk factors for distress. Path analysis was used to examine associations among identified risk factors. Results Elevated global distress was reported by 15.1% of survivors. Cancer-related pain was associated with elevated distress (OR 8.72; 95% CI, 5.32 – 14.31). Survivors who reported moderate learning or memory problems were more likely to have elevated distress than survivors who reported no learning or memory problems (OR 3.27; 95% CI, 2.17 – 4.93). Path analysis implied that cancer-related pain has a direct effect on distress symptoms and an indirect effect through socioeconomic status and learning or memory problems. Similar results were observed for learning or memory problems. Conclusions Childhood cancer-related morbidities including pain and learning or memory problems appear to be directly and indirectly associated with elevated distress symptoms decades after treatment. Understanding these associations may help inform intervention targets for survivors of childhood cancer experiencing symptoms of distress. Implications for cancer survivors A subset of long-term childhood cancer survivors experience significant emotional distress. Physical and cognitive late effects may contribute to these symptoms.

    Objective To evaluate prevalence, severity, and co-occurrence of, and risk factors for depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms over the first year after ARDS. Design Prospective longitudinal cohort study. Settings 41 ARDS Network hospitals across the U.S. Patients 698 ARDS survivors. Interventions None. Measurements and Main Results Psychiatric symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS) and Impact of Event Scale–Revised (IES-R) at 6 and 12 months. Adjusted prevalence ratios for substantial symptoms (binary outcome) and severity scores were calculated using Poisson and linear regression, respectively. During 12 months, a total of 416 of 629 patients (66%) with at least one psychiatric outcome measure had substantial symptoms in at least one domain. There was a high and almost identical prevalence of substantial symptoms (36%, 42%, and 24% for depression, anxiety and PTSD) at 6 and 12 months. The most common pattern of co-occurrence was having symptoms of all 3 psychiatric domains simultaneously. Younger age, female sex, unemployment, alcohol misuse, and greater opioids use in the ICU were significantly associated with psychiatric symptoms, while greater severity of illness and ICU length of stay were not associated. Conclusions Psychiatric symptoms occurred in two-thirds of ARDS survivors with frequent co-occurrence. Sociodemographic characteristics and in-ICU opioids administration, rather than traditional measures of critical illness severity, should be considered in identifying patients at highest risk for psychiatric symptoms during recovery. Given high co-occurrence, ARDS survivors should be simultaneously evaluated for a full spectrum of psychiatric sequelae to maximize recovery. PMID:26807686

    Acute respiratory distress syndrome (ARDS) is a life-threatening condition with multiple causes and a high mortality rate. Approximately 150,000 cases are reported in the United States annually, making ARDS a public health concern. Management of the condition is complex because of its severity, and medical imaging is essential for both the diagnosis and management of ARDS. This article introduces common signs, symptoms, risk factors, and causes of ARDS. Diagnostic criteria, histopathology, treatment strategies, and prognostic information also are discussed. The article explains the value of medical imaging studies of ARDS, especially radiography, computed tomography, and ultrasonography.

    Adult respiratory distress syndrome (ARDS) has now been described as a sequela to such diverse conditions as burns, amniotic fluid embolism, acute pancreatitis, trauma, sepsis and damage as a result of elective surgery in general. Patients with ARDS require immediate intubation, with the average patient now being ventilated for between 8 and 11 days. While the acute management of ARDS is conducted by the critical care team, almost any surgical patient can be affected by the condition and we believe that it is important that a broader spectrum of hospital doctors gain an understanding of the nature of the pathology and its current treatment.

    The purposes of this study were to estimate the prevalence of emotional distress in a large cohort of adult survivors of childhood cancer and to evaluate the interrelationship of risk factors including cancer-related late effects. Adult survivors of childhood cancer (N = 1,863), median age of 32 years at follow-up, completed comprehensive medical evaluations. Clinically relevant emotional distress was assessed using the Brief Symptom Inventory 18 and was defined as T-scores ≥63. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multivariable logistic regression models to identify risk factors for distress. Path analysis was used to examine associations among identified risk factors. Elevated global distress was reported by 15.1% of survivors. Cancer-related pain was associated with elevated distress (OR 8.72; 95% CI, 5.32-14.31). Survivors who reported moderate learning or memory problems were more likely to have elevated distress than survivors who reported no learning or memory problems (OR 3.27; 95% CI, 2.17-4.93). Path analysis implied that cancer-related pain has a direct effect on distress symptoms and an indirect effect through socioeconomic status and learning or memory problems. Similar results were observed for learning or memory problems. Childhood cancer-related morbidities including pain and learning or memory problems appear to be directly and indirectly associated with elevated distress symptoms decades after treatment. Understanding these associations may help inform intervention targets for survivors of childhood cancer experiencing symptoms of distress. A subset of long-term childhood cancer survivors experience significant emotional distress. Physical and cognitive late effects may contribute to these symptoms.

    Acute respiratory distress syndrome (ARDS) is the clinical manifestation of an acute lung injury caused by a variety of direct and indirect injuries to the lung. The cardinal clinical feature of ARDS, refractory arterial hypoxemia, is the result of protein-rich alveolar edema with impaired surfactant function, due to vascular leakage and dysfunction with consequently impaired matching of ventilation to perfusion. Better understanding of the pathophysiology of ARDS has led to the development of novel therapies, pharmacological strategies, and advances in mechanical ventilation. However, protective ventilation is the only confirmed option in ARDS management improving survival, and few other therapies have translated into improved oxygenation or reduced ventilation time. The development of innovative therapy options, such as extracorporeal membrane oxygenation, have the potential to further improve survival of this devastating disease.

    To evaluate the degree of psychological distress in adult childhood cancer survivors in Switzerland and to characterize survivors with significant distress. Childhood cancer survivors who were age younger than 16 years when diagnosed between 1976 and 2003, had survived more than 5 years, and were currently age 20 years or older received a postal questionnaire. Psychological distress was assessed using the Brief Symptom Inventory (BSI). Raw scores were transformed into T scores according to the German norm sample, and the proportion of participants being at increased risk for psychological distress was calculated (case rule: T > or = 63). t tests and univariable and multivariable logistic regressions were used for statistical analyses. One thousand seventy-six survivors (63.% of eligible survivors, 71.9% of contacted survivors) returned the questionnaire, 987 with complete data on BSI. Comparison with the norm populations showed lower T scores (T < 50) in the Global Severity Index (GSI; T = 46.2), somatization (T = 47.6), obsessive-compulsive tendencies (T = 46.9), and anxiety (T = 48.4). However, more childhood cancer survivors (especially women) had increased distress for GSI (14.4%), interpersonal sensitivity (16.5%), depression (13.4%), aggression (16.9%), and psychotic tendencies (15.6%) than the expected 10% from the norm population. Caseness was associated with female sex, being a single child, older age at study, and self-reported late effects, especially psychological problems. Results show that childhood cancer survivors, on average, have less psychological distress than a norm population but that the proportion of survivors at risk for high psychological distress is disproportionally large. Monitoring psychological distress in childhood cancer survivors may be desirable during routine follow-up, and psychological support should be offered as needed.

    Acute respiratory distress syndrome (ARDS) is the general term used for severe acute respiratory failure of diverse aetiology. It is associated with a high morbidity, mortality (50-70%), and financial costs. Regardless of aetiology, the basic pathogenesis of ARDS is a systemic inflammatory response leading to a diffuse inflammatory process that involves both lungs, thus causing diffuse alveolar and endothelial damage with increased pulmonary capillary permeability and excessive extravascular lung water accumulation. ARDS is commonly associated with sepsis and multiple organ failure. The clinical picture involves progressive hypoxaemia, radiographic evidence of pulmonary oedema, decreased lung compliance and pulmonary hypertension. Despite the scientific and technological progress in critical care medicine, there is no specific ARDS therapy available at the moment and its management remains supportive. Therapeutic goals include resolution of underlying conditions, maintenance of acceptable gas exchange and tissue oxygenation and prevention of iatrogenic lung injury. Many new specific therapeutic strategies have been developed, however, most of them require further scientific evaluation. The paper reviews definition, basic pathogenesis and pathophysiology of ARDS and discusses current concepts of therapeutic possibilities of ARDS.

    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.

    Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) represent a continuum of a clinical syndrome of respiratory failure due to refractory hypoxia. Acute respiratory distress syndrome is differentiated from ALI by a greater degree of hypoxemia and is associated with higher morbidity and mortality. The mortality for ARDS ranges from 22-41%, with survivors usually requiring long-term rehabilitation to regain normal physiologic function. Numerous pharmacologic therapies have been studied for prevention and treatment of ARDS; however, studies demonstrating clear clinical benefit for ARDS-related mortality and morbidity are limited. In this focused review, controversial pharmacologic therapies that have demonstrated, at minimum, a modest clinical benefit are discussed. Three pharmacologic treatment strategies are reviewed in detail: corticosteroids, fluid management, and neuromuscular blocking agents. Use of corticosteroids to attenuate inflammation remains controversial. Available evidence does not support early administration of corticosteroids. Additionally, administration after 14 days of disease onset is strongly discouraged. A liberal fluid strategy during the early phase of comorbid septic shock, balanced with a conservative fluid strategy in patients with ALI or ARDS during the postresuscitation phase, is the optimum approach for fluid management. Available evidence supports an early, short course of continuous-infusion cisatracurium in patients presenting with severe ARDS. Evidence of safe and effective pharmacologic therapies for ARDS is limited, and clinicians must be knowledgeable about the areas of controversies to determine application to patient care.

  4. Maladaptive behavior in survivors: dysexecutive survivor syndrome.

    2012-12-01

    This paper attempts to answer the question: why does normal, goal-directed, purposeful, and coordinated behavior fragment in a survival situation? Events accompanying the initial impact phase of a survival incident are characterized by speed, danger, violence, and uncontrollability. The following recoil phase is known to produce behavioral and cognitive impairment that leads to a reduced ability to produce a response that is meaningful and may result in tonic immobility. The author argues that the commonly witnessed responses among survivors comprise a subset of known behaviors, including loss of initiative, stereotypy, perseveration of thought and action, hyperkinesia, hypokinesia, and, in extreme cases, akinesia or cognitive paralysis. These behaviors are characteristic of executive dysfunction and a model is given suggesting how this condition may arise under survival conditions. The case is presented that during the initial phase of a survival incident, victims show a transient, nonclinical dysexecutive syndrome. This model should aid survival training and provide a context for conducting behavioral autopsies by accident investigators.

    Health-related quality of life (HRQoL) and return to work are important outcomes in critical care medicine, reaching beyond mortality. Little is known on factors predictive of HRQoL and return to work in critical illness, including the acute respiratory distress syndrome (ARDS), and no evidence exists on the role of quality of care (QoC) for outcomes in survivors of ARDS. It is the aim of the DACAPO study ("Surviving ARDS: the influence of QoC and individual patient characteristics on quality of life") to investigate the role of QoC and individual patient characteristics on quality of life and return to work. A prospective, observational, multi-centre patient cohort study will be performed in Germany, using hospitals from the "ARDS Network Germany" as the main recruiting centres. It is envisaged to recruit 2400 patients into the DACAPO study and to analyse a study population of 1500 survivors. They will be followed up until 12 months after discharge from hospital. QoC will be assessed as process quality, structural quality and volume at the institutional level. The main outcomes (HRQoL and return to work) will be assessed by self-report questionnaires. Further data collection includes general medical and ARDS-related characteristics of patients as well as sociodemographic and psycho-social parameters. Multilevel hierarchical modelling will be performed to analyse the effects of QoC and individual patient characteristics on outcomes, taking the cluster structure of the data into account. By obtaining comprehensive data at patient and hospital level using a prospective multi-centre design, the DACAPO-study is the first study investigating the influence of QoC on individual outcomes of ARDS survivors.

    all species that we work with? What do we define as acute onset? Most human ARDS cases occur while patients are in hospital being treated for other problems, whereas many of our patients present already in respiratory distress. If we are unable to ventilate patients for economic or practical reasons, what do we use as the equivalent of the Pao2/Flo, ratio'? Reliance on the pathologist is not reasonable, because many disease processes can look similar to ARDS under the microscope. If anything, ALI and ARDS are clinical diagnoses. It is time for veterinarians to reach a consensus on the definition for ALI and ARDS in our patients. Only when we have a consensus of definition can rational prospective clinical trials of therapies be designed.

    ABSTRACT Objective: To investigate the presence of depression and anxiety symptoms in survivors of the Haiti earthquake who were assisted by a healthcare team from the Hospital Israelita Albert Einstein, and to evaluate the impact that losing a family member during this catastrophe could have on the development of these symptoms. Methods: Forty survivors of the Haiti earthquake who were assisted by the healthcare team between February and March of 2010 were included in this study. All subjects underwent a semi-structured interview. The group was divided into Group A (individuals who had some death in the family due to the disaster) and Group B (those who did not lose any family member). Results: A total of 55% of the subjects had depression symptoms whereas 40% had anxiety symptoms. The individuals who lost a family member were five times more likely to develop anxiety and depression symptoms than those who did not. Conclusion: Catastrophe victims who lost at least one family member due to the disaster were more likely to develop anxiety and depression symptoms. To these individuals, as well as others showing psychological distress, should be offered early mental health care to help them cope with the great emotional distress inherent in these situations.

    Childhood cancer survivors are at risk for emotional distress symptoms, but symptom comorbidity has not been previously examined. This study examined distress profiles for adult survivors of childhood cancer diagnosed between 1970 and 1999. Self-reported depression, anxiety, and somatization symptoms from Brief Symptom Inventory 18 were examined in survivors (n = 16,079) and siblings (n = 3085) from the Childhood Cancer Survivor Study. A latent profile analysis identified clusters of survivors with individual and comorbid symptoms. Disease, treatment, and demographic predictors of distress comorbidity patterns were examined with multinomial logistic regressions. Four clinically relevant profiles were identified: low distress on all subscales (asymptomatic, 62%), high distress on all subscales (comorbid distress, 11%), elevated somatization (somatic symptoms, 13%), and elevated depression and anxiety (affective distress, 14%). Compared with siblings, fewer survivors were asymptomatic (62% vs 74%, P < .0001), and more had comorbid distress (11% vs 5%, P < .0001). Survivors of leukemia (odds ratio [OR], 1.34; 95% confidence interval [CI], 1.12-1.61), central nervous system tumors (OR, 1.30; 95% CI, 1.05-1.61), and sarcoma (OR, 1.26; 95% CI, 1.01-1.57) had a greater risk of comorbid distress than survivors of solid tumors. Psychoactive medications were associated with comorbid distress (P < .0001), and this suggested that this group was refractory to traditional medical management. Comorbid distress was associated with poor perceived health (OR, 31.7; 95% CI, 23.1-43.3), headaches (OR, 3.2; 95% CI, 2.8-3.7), and bodily pain (OR, 4.0; 95% CI, 3.2-5.0). A significant proportion of survivors are at risk for comorbid distress, which may require extensive treatment approaches beyond those used for individual symptoms.

    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

    Return to work after treatment completion is important for both cancer survivors and society. Financial distress is one of the factors that may influence the return to work in cancer survivors. However, this relationship has not been well investigated. This study aimed to determine the rate of return to work and its relation to financial distress among Iranian cancer survivors. This descriptive-correlational study was undertaken among 165 cancer survivors who completed their initial treatments and had no signs of active cancer. The Return to Work questionnaire and Financial Distress/Financial Well-Being Scale were used for data collection. Data were analyzed using SPSS statistical software. After initial treatments, 120 cancer survivors (72%) had returned to work, of which 50 patients (42%) had returned to full-time work and 70 (58%) reduced their work hours and returned to part-time work. Cancer survivors also reported high levels of financial distress. In addition, the financial distress was lower among patients who had returned completely to work, in comparison to patients who had quit working for cancer-related reasons (p=0.001) or returned to work as part-time workers (p=0.001). The findings showed that a high percent of Iranian cancer survivors had not returned to their jobs or considerably reduced working hours after treatment completion. Accordingly, due to high levels of financial distress experienced by participants and its relation to return to work, designing rehabilitation programs to facilitate cancer survivor return to work should be considered.

    An evaluation is made of lung function and quality of life 6 months after discharge from the Intensive Care Unit (ICU) among survivors of acute respiratory distress syndrome (ARDS) due to pandemic 2009 influenza A H1N1, based on studies of lung function and the EQ-5D health questionnaire. Case series. The ICU of Dr. Leónidas Lucero Acute Cases Municipal Hospital, Bahía Blanca, Argentina. PATIENTS discharged from the ICU who had been admitted with ARDS in 2009 due to influenza A H1N1. Eleven patients were studied. Seven were positive for influenza H1N1 and four were negative. The mean age was 37±9.5 years, and 73% were males. Quality of life, as measured by the EQ-5D, showed changes in the 5 components in all patients, particularly in the pain/discomfort dimension 1.55±0.52; health status (EQ%health) was 70%±24. The indices adjusted for Argentina were Time Trade Off (TTO) 0.903±0.085 and Visual Analog Scale (VAS) 0.827±0.153. In all patients, spirometry and the study of pulmonary diffusion (DLCO) showed values of >80%. There was no correlation between lung diffusion and quality of life (%DLCO and EQ%health). A correlation was observed between quality of life and TTO (EQ%health and TTO), and between quality of life and the VAS score (EQ%health and VAS). Although the sample is small, our results suggest that patients with ARDS due to influenza A H1N1 evaluated 6 months after discharge from the ICU show no deterioration of lung function, and the impact on quality of life is moderate-in contrast to the situation found in patients with ARDS of other etiologies.

    The unique characteristics of pulmonary circulation and alveolar-epithelial capillary-endothelial barrier allow for maintenance of the air-filled, fluid-free status of the alveoli essential for facilitating gas exchange, maintaining alveolar stability, and defending the lung against inhaled pathogens. The hallmark of pathophysiology in acute respiratory distress syndrome is the loss of the alveolar capillary permeability barrier and the presence of protein-rich edema fluid in the alveoli. This alteration in permeability and accumulation of fluid in the alveoli accompanies damage to the lung epithelium and vascular endothelium along with dysregulated inflammation and inappropriate activity of leukocytes and platelets. In addition, there is uncontrolled activation of coagulation along with suppression of fibrinolysis and loss of surfactant. These pathophysiological changes result in the clinical manifestations of acute respiratory distress syndrome, which include hypoxemia, radiographic opacities, decreased functional residual capacity, increased physiologic deadspace, and decreased lung compliance. Resolution of acute respiratory distress syndrome involves the migration of cells to the site of injury and re-establishment of the epithelium and endothelium with or without the development of fibrosis. Most of the data related to acute respiratory distress syndrome, however, originate from studies in adults or in mature animals with very few studies performed in children or juvenile animals. The lack of studies in children is particularly problematic because the lungs and immune system are still developing during childhood and consequently the pathophysiology of pediatric acute respiratory distress syndrome may differ in significant ways from that seen in acute respiratory distress syndrome in adults. This article describes what is known of the pathophysiologic processes of pediatric acute respiratory distress syndrome as we know it today while also presenting the much

    BACKGROUND The validity of the Distress Thermometer (DT) as a screen for psychological distress in young adult (YA) cancer survivors was assessed by comparing it with results of a psychiatric diagnostic interview, the Structured Clinical Interview for the DSM-IV (SCID), in order to evaluate accuracy of the DT and identify optimal cut-off scores for this population. METHODS 247 survivors (age 18–40 years) completed the DT and SCID. Based on the SCID, participants were classified as having: 1) One or more SCID diagnoses; 2) Significant symptoms, but no SCID diagnosis; or 3) No significant SCID symptoms. ROC analyses determined sensitivity and specificity of all possible DT cut-off scores for detecting survivors with a SCID diagnosis, and subsequently for survivors with significant SCID symptoms or a SCID diagnosis. RESULTS The recommended DT cut-off score of ≥ 5 failed to identify 31.81% of survivors with a SCID diagnosis (sensitivity 68.18%, specificity 78.33%), and 32.81% of survivors with either Significant SCID symptoms or a SCID diagnosis. No alternative DT cut-off score met criteria for acceptable sensitivity (≥.85) and specificity (≥.75). CONCLUSIONS The DT does not reliably identify YA cancer survivors with psychiatric problems identified by a “gold standard” structured psychiatric interview; the DT should not be used as a stand-alone psychological screen in this population.

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.

    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

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

    Public stigma is a major source of stress for cancer survivors. However, factors that buffer or exacerbate the negative effects of public stigma on psychological distress have not been elucidated. This study examined how perceived public stigma affects psychological distress as mediated by cancer disclosure, internalized reactions to stigma, and social support availability. Cross-sectional study. The study was conducted in South Korea. The study sample was 223 adolescent and young adult survivors of childhood cancer diagnosed before the age of 19 and currently between 15 and 39 years old. Psychological distress was assessed using the Brief Symptom Inventory-18. Structural equation modeling was used with 1000 bootstrap samples. The goodness of model fit was acceptable. Public stigma perceived by cancer survivors influenced psychological distress via cancer disclosure, internalized shame, and social support availability. Higher levels of perceived public stigma predicted higher levels of internalized shame and self-blame and lower levels of social support availability, which subsequently increased psychological distress. Higher levels of perceived public stigma predicted lower levels of disclosure about cancer history and experiences. Cancer disclosure indirectly ameliorated psychological distress by reducing internalized shame. This study offers evidence that cognitive and social factors play important roles in mediating the effects of perceived public stigma on psychological distress in Korean cancer survivors. A greater understanding of factors that influence psychological distress may help psychosocial oncology service providers to identify childhood cancer survivors in need of psychosocial services and provide them with appropriate resources and interventions.

    This cross-sectional study aims to explore the relationship between different types and sources of social support and psychological distress by age and sex among survivors living in temporary housing 10 months after the Great East Japan Earthquake. Self-reported questionnaires/structured interviews administered from January to March 2012 recorded demographic characteristics, damage involving participants' families, social support, and psychological distress. Data on 296 participants aged 20 years or more from nine temporary housing complexes in Otsuchi were analyzed; K6 scores indicating psychological distress averaged 5.1 (standard deviation, 5.9; range, 0-24). Multiple logistic regression analyses indicated differences among types and sources of social support with regard to psychological distress by age and sex among disaster survivors. For men aged less than 65 years, social support by family was related to lower psychological distress. For women aged 65 years or more, emotional support from family, informational and instrumental support, and social companionship from friends in their own temporary housing complexes were related to less psychological distress. Differences in age and sex were related to different sources of social support in relation to psychological distress. It is necessary to pay more attention to those who lost family members in the disaster, especially men aged less than 65 years. It may also be necessary to support survivors in making friends when they relocate to temporary housing, especially women aged 65 years or more. © 2015 The Authors.

    Although, miliary tuberculosis is an unusual cause of severe acute respiratory failure, we describe nine patients with miliary tuberculosis who developed adult respiratory distress syndrome. This complication occurred in seven patients despite treatment with antituberculous drugs. In two patients who developed the syndrome, miliary tuberculosis was diagnosed only at postmortem. The presence of pulmonary hypertension in all cases and disseminated intravascular coagulation in seven cases suggests a possible pathophysiologic relationship with severe pulmonary vascular damage. The high mortality rate (88.8%) was associated with nonpulmonary organ system failure. Miliary tuberculosis should be considered in patients with adult respiratory distress syndrome of unknown etiology, and simple diagnostic procedures such as sputum, bronchial brushing, and gastric examination should be followed by invasive diagnostic procedures to confirm this etiology. Since untreated miliary tuberculosis is usually fatal, early recognition of this disease is of great importance, and specific therapy may play a lifesaving role.

    The validity of the Distress Thermometer (DT) as a screen for psychological distress in young adult cancer survivors was assessed by comparing it with the results of a psychiatric diagnostic interview, the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) (SCID), to evaluate the accuracy of the DT and identify optimal cutoff scores for this population. A total of 247 survivors aged 18 to 40 years completed the DT and SCID. Based on the SCID, participants were classified as having: 1) ≥ 1 SCID diagnoses; 2) significant symptoms, but no SCID diagnosis; or 3) no significant SCID symptoms. Receiver operating characteristic analyses determined the sensitivity and specificity of all possible DT cutoff scores for detecting survivors with a SCID diagnosis, and subsequently for survivors with significant SCID symptoms or a SCID diagnosis. The recommended DT cutoff score of ≥5 failed to identify 31.81% of survivors with a SCID diagnosis (sensitivity of 68.18% and specificity of 78.33%), and 32.81% of survivors with either significant SCID symptoms or a SCID diagnosis. No alternative DT cutoff score met the criteria for acceptable sensitivity (≥85%) and specificity (≥75%). The DT does not reliably identify young adult cancer survivors with psychiatric problems identified by a "gold standard" structured psychiatric interview. Therefore, the DT should not be used as a stand-alone psychological screen in this population. Cancer 2016;122:296-303. © 2015 American Cancer Society. © 2015 American Cancer Society.

    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.

    The purposes of this investigation were to compare psychological distress among cancer survivors' social network members with different relationships with the survivors and to compare their reported levels of distress with population norms. Participants in this investigation included spouses/significant others (n = 153), siblings (n = 11), adult children (n = 25), parents (n = 10), cousins (n = 6), and friends/others (n = 10) of English or Spanish speaking women with breast cancer and English speaking men with prostate cancer. Network members reported on their symptoms of depression, positive and negative affect, anxiety, and relationship satisfaction. The psychological distress among all relationship types was similar. Spouses, and to a lesser extent, adult children were the only groups whose levels of psychological distress were above population norms. Relationship satisfaction was negatively associated with social network members' psychological distress, and female network members had higher levels of depression than male network members due, in part, to higher perceived stress among female network members. These findings highlight the need to consider the potentially deleterious impact of cancer not just on survivors' spouses, but on other social network members as well and to make services available to network members who may play an important role in the survivor's care and adjustment.

    The aim of the study is to evaluate the presence of PTSD diagnosis, psychological distress and post-traumatic symptoms in a population of young earthquake survivors after L'Aquila earthquake. Between April 2009 and January 2010, 187 young people seeking help consecutively at the Service for Monitoring and early Intervention against psychoLogical and mEntal suffering in young people (SMILE) of L'Aquila University Psychiatric Department, underwent clinical interview with the Semi-Structured Clinical Interview DSM-IV-I and-II (SCID-I and SCID-II) and psychometric evaluation with Impact Event Scale-Revised (IES-R) and General Health Questionnaire-12 items (GHQ-12). 44.2% and 37.4% respectively, showed high and moderate levels of psychological distress. 66.7% reported the presence of a significant post-traumatic symptoms (Post-traumatic Syndrome) with an IES-R>28, while a diagnosis of PTSD was made in 13.8% of the sample. The obsessive-compulsive trait, female sex and high level of distress (GHQ ≥20) appear to be the main risk factors for the development of PTSD than those who had a post-traumatic syndrome for which the displacement and social disruption, appear to be more associated with post-traumatic aftermaths. Our findings, in line with recent literature, confirm that a natural disaster produces an high psychological distress with long-term aftermaths. Early intervention for survivors of collective or individual trauma, regardless of the presence of a PTSD diagnosis should be a primary goal in a program of Public Health.

  6. Idioms of distress among trauma survivors: subtypes and clinical utility.

    2010-06-01

    In this introduction to the Special Issue on Trauma and Idioms of Distress, we provide an overview of the concept and typology of "idioms of distress," focusing particularly on their clinical utility. This includes the role of idioms as indicators of trauma exposure, of various types of psychopathology and of levels of distress, risk and functioning. It likewise includes the fact that idioms of distress may profoundly influence the personal meaning of having a trauma-related disorder, may shape the interpersonal course of the disorder and may pattern help-seeking and self-treatment. Finally, it illustrates the fact that idioms may also help clinicians understand sufferers' views of the causes of their distress, constitute key therapeutic targets and help increase therapeutic empathy and treatment adherence. This special issue focuses on the role played by idioms of distress in the local trauma ontology, the associations between the idioms and psychiatric disorders occurring in the context of trauma and the mechanisms by which the idioms profoundly influence the personal and interpersonal course of trauma-related disorders.

  7. The relationship between loss of parents in the holocaust, intrusive memories, and distress among child survivors.

    The prevalence of intrusive memories of the Holocaust and their relationship to distress was examined among 272 child survivors in Israel. Using attachment theory as a conceptual framework, the authors also examined the effects of type of experience and loss of parents in the Holocaust, psychological resources, other life events, and sociodemographic characteristics on distress and symptomatic behavior. Eighty five percent of the participants reported suffering from intrusive memories. Structural equation modeling showed that survivors who lost one or both parents in the Holocaust suffered more distress because of more intrusive memories. These findings suggest that intrusive memories may be part of unfinished mourning processes related to the loss of parents in the Holocaust.

    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.

    Unmanaged distress has been shown to adversely affect survival and quality of life in breast cancer survivors. Fortunately, distress can be managed and even prevented with appropriate evidence-based interventions. Therefore, the objective of this systematic review was to synthesize the published literature around predictors of distress in female breast cancer survivors to help guide targeted intervention to prevent distress. Relevant studies were located by searching MEDLINE, Embase, PsycINFO, and CINAHL databases. Significance and directionality of associations for commonly assessed candidate predictors (n ≥ 5) and predictors shown to be significant (p ≤ 0.05) by at least two studies were summarized descriptively. Predictors were evaluated based on the proportion of studies that showed a significant and positive association with the presence of distress. Forty-two studies met the target criteria and were included in the review. Breast cancer and treatment-related predictors were more advanced cancer at diagnosis, treatment with chemotherapy, longer primary treatment duration, more recent transition into survivorship, and breast cancer recurrence. Manageable treatment-related symptoms associated with distress included menopausal/vasomotor symptoms, pain, fatigue, and sleep disturbance. Sociodemographic characteristics that increased the risk of distress were younger age, non-Caucasian ethnicity, being unmarried, and lower socioeconomic status. Comorbidities, history of mental health problems, and perceived functioning limitations were also associated. Modifiable predictors of distress were lower physical activity, lower social support, and cigarette smoking. This review established a set of evidence-based predictors that can be used to help identify women at higher risk of experiencing distress following completion of primary breast cancer treatment.

    Prostate cancer survivors have reported cognitive complaints following treatment, and these difficulties may be associated with survivors' ongoing cancer-related distress. Intolerance of uncertainty may exacerbate this hypothesized relationship by predisposing individuals to approach uncertain situations such as cancer survivorship in an inflexible and negative manner. We investigated whether greater cognitive complaints and higher intolerance of uncertainty would interact in their relation to more cancer-related distress symptoms. This cross-sectional, questionnaire-based study included 67 prostate cancer survivors who were 3 to 5 years post treatment. Hierarchical multiple regression analyses tested the extent to which intolerance of uncertainty, cognitive complaints, and their interaction were associated with cancer-related distress (measured with the Impact of Event Scale-Revised; IES-R) after adjusting for age, education, physical symptoms, and fear of cancer recurrence. Intolerance of uncertainty was positively associated with the IES-R avoidance and hyperarousal subscales. More cognitive complaints were associated with higher scores on the IES-R hyperarousal subscale. The interaction of intolerance of uncertainty and cognitive complaints was significantly associated with IES-R intrusion, such that greater cognitive complaints were associated with greater intrusive thoughts in survivors high in intolerance of uncertainty but not those low in it. Prostate cancer survivors who report cognitive difficulties or who find uncertainty uncomfortable and unacceptable may be at greater risk for cancer-related distress, even 3 to 5 years after completing treatment. It may be beneficial to address both cognitive complaints and intolerance of uncertainty in psychosocial interventions. Copyright © 2014 John Wiley & Sons, Ltd.

    To evaluate associations between prepregnancy lifestyle factors, psychologic distress and adverse pregnancy outcomes among female survivors of childhood cancer. We examined pregnancies of 1192 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, psychologic distress and pregnancy outcomes. Interactions between lifestyle factors, psychologic distress, type of cancer and cancer treatment were assessed in multivariable models. The median age of study participants at the beginning of pregnancy was 28 years (range, 14-45). Among 1858 reported pregnancies, there were 1300 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 with those who had never smoked, survivors with >5 pack-years smoking history had a higher risk for miscarriage among those treated with >2.5 Gray (Gy) uterine radiation (OR, 53.9; 95% CI, 2.2-1326.1) 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 = .01). Although most lifestyle factors and psychologic 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.

  13. Pulmonary and extrapulmonary acute respiratory distress syndrome: myth or reality?

    PubMed

    2008-02-01

    The pathogenesis of acute respiratory distress syndrome has been explained by the presence of a direct (pulmonary) or indirect (extrapulmonary) insult to the lung parenchyma. Evidence indicates that the pathophysiology of acute respiratory distress syndrome may differ according to the type of the insult. This article presents a brief overview of the differences between pulmonary and extrapulmonary acute respiratory distress syndrome, and discusses the interactions between lung functional, morphological aspects, and response to different therapies, both in experimental models and in patients with acute respiratory distress syndrome. Many researchers recognize that experimental pulmonary and extrapulmonary acute respiratory distress syndrome are not identical when considering morpho-functional aspects, the response to positive end-expiratory pressure and recruitment manoeuvre, prone position and other adjunctive therapies. Contradictory results have been reported in different clinical studies, however, which may be attributed to the difficulty of classifying acute respiratory distress syndrome in one or the other category, and being confident of the onset, the phase and the severity of acute respiratory distress syndrome in all patients. Heterogeneous acute respiratory distress syndrome patients are still considered to suffer from one syndrome, and are treated in the same way. Understanding the range of different pathways that lead to pulmonary dysfunction makes it possible to better target clinical treatment.

    Acute respiratory distress syndrome (ARDS) is a condition with a high morbidity and mortality rate, and treatment is often long and costly. Prone positioning is a rarely used intervention for patients with this syndrome, although research suggests it may be effective. A literature search was undertaken to examine the effects of prone positioning on oxygenation, morbidity and mortality in patients with ARDS. It revealed that prone positioning, when used with low tidal volume ventilation over an extended period, may reduce mortality rates in selected patients with severe ARDS. The selection of patients with severe ARDS for prone positioning should be done on a case-by-case basis to maximise benefits and minimise complications. Further research is required on the use of prone positioning in patients with severe ARDS to support or disclaim the therapy's use in practice, and to compare confounding variables such as ideal prone duration and mechanical versus manual pronation.

    Hyperleukocytic leukemias are a small proportion of leukemias that have white blood cell count > 100 x 10(9)/l, most of them are leukemic blast cells. These leukemias have a grave prognosis because they can develop a leukostasis syndrome which describes: the acute onset of pulmonary failure and, often, neurologic deficits and disseminated intravascular coagulation (DIC). The leukostasis is produced by the mechanical obstruction of vascular bed by blast cells, which can be induced by the spontaneous tumor lysis or as a side effect of cytotoxic drugs. So, hyperleukocytic leukemias require early and vigorous measures to decrease the white blood cell count, using leukapheresis and/or chemotherapy, before pulmonary failure exists. Then, it is possible to reverse the lesions. We report two cases of acute myeloblastic leukemia with a white blood count > 100 x 10(9)/l, that developed a respiratory distress syndrome and died. The postmortem examination has been done in one of the cases.

    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.

    Family functioning appears to be a predictor of psychological distress among childhood cancer survivors and their family members; however, relatively little is known about patterns in those families that are psychologically at-risk. The purpose of this study was to identify distinct clusters of families that include childhood cancer survivors, and to evaluate differences between the clusters with respect to anxiety, depression, and post-traumatic stress symptoms (PTSS). Childhood cancer survivors and their parents (247 individuals: 88 adolescent cancer survivors, 87 mothers, and 72 fathers) completed self-report questionnaires. Perceptions of family functioning were assessed using the Family Relationship Index and its three dimensions (cohesiveness, expressiveness, and conflict), and individuals were classified into groups via a cluster analytic approach. State-trait anxiety, depression, and PTSS were assessed to all of the participants. The individuals were classified into three types: One cluster featured high cohesiveness, high expressiveness, and low conflict ('Supportive-type', n=102); a second cluster featured low cohesiveness, low expressiveness, and high conflict ('Conflictive-type', n=32); and a third cluster had moderate cohesiveness, moderate expressiveness, and moderate conflict ('Intermediate-type', n=113). Among the three types, an analysis of variance revealed that 'Conflictive-type' members had the highest levels of PTSS, depression, and state-trait anxiety. These findings suggest that perceptions of family functioning are related to psychological distress in family members of childhood cancer survivors. A family-focused intervention might be a useful approach to targeting emotional distress in these families, particularly for families with a 'Conflictive-type' family member.

    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.

    Metacognitive therapy (MCT) is an effective psychological treatment for a range of emotional disorders. However, the applicability of MCT to treating emotional distress in physical health populations has yet to be tested. The present study examined the potential of MCT for alleviating emotional distress in adolescent and young adult cancer (AYAC) survivors. Twelve AYAC survivors, aged 18-23, who had completed acute medical treatment participated in this pilot open trial with 6 months follow-up. Each participant completed a baseline period followed by 8-14 sessions of MCT that targeted perseverative thinking (worry and rumination), attentional control, and metacognitive beliefs. The primary outcome variable was severity of depression and anxiety symptoms as measured by the Hospital Anxiety and Depression Scale (HADS). MCT was associated with large and statistically significant reductions in anxiety, depression, trauma symptoms, and metacognitive beliefs and processes. In the intention-to-treat sample, 50% of participants met standardized criteria for recovery on the HADS at posttreatment and these gains were maintained through to 6-month follow-up. MCT is a promising transdiagnostic approach to treating different forms of emotional distress in AYAC survivors. Further investigation in controlled trials is now warranted.

  20. Acute respiratory distress syndrome after cardiac surgery

    Acute respiratory distress syndrome (ARDS) is a leading cause of postoperative respiratory failure, with a mortality rate approaching 40% in the general population and 80% in the subset of patients undergoing cardiac surgery. The increased risk of ARDS in these patients has traditionally been associated with the use of cardiopulmonary bypass (CPB), the need for blood product transfusions, large volume shifts, mechanical ventilation and direct surgical insult. Indeed, the impact of ARDS in the cardiac population is substantial, affecting not only survival but also in-hospital length of stay and long-term physical and psychological morbidity. No patient undergoing cardiac surgery can be considered ARDS risk-free. Early identification of those at higher risk is crucial to warrant the adoption of both surgical and non-surgical specific preventative strategies. The present review focuses on epidemiology, risk assessment, pathophysiology, prevention and management of ARDS in the specific setting of patients undergoing cardiac surgery. PMID:27867583

    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?

    Specimen arteriography, morphometry, and light and electron microscopy were used for examination of the pulmonary vasculature of 22 patients who died with the adult respiratory distress syndrome (ARDS), for the purpose of defining the lesions that contribute to pulmonary hypertension in this setting. The different lesions correlated with the duration rather than the cause of ARDS. Thromboemboli occurred in 21 patients, and macrothrombi found at autopsy correlated with the number of filling defects on antemortem angiography. Acute endothelial injury was documented ultrastructurally even in intermediate and late-stage patients. Fibrocellular intimal obliteration of arteries, veins, and lymphatics and infective vasculitis were prominent in those surviving beyond 10 days. In long-term survivors, tortuous arteries and irregularly dilated capillaries were striking features. Peripheral extension of vascular smooth muscle and a significant increase in the percentage of medial thickness of muscular arteries with duration of ARDS were noted. The pathogenesis and clinical significance of these lesions is discussed. Images Figure 1 Figure 2 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Figure 12 Figure 13 PMID:6859225

    The application of distending pressure to 40 babies with the respiratory distress syndrome (RDS) is described. Pressures greater than 10 cm H2O were rarely used. On starting distending pressure, considerable improvements in blood gases occurred in all but 4 babies, 2 of whom had pneumothoraces and the other rapidly deteriorated and died from an intraventricular haemorrhage shortly afterwards. In 27 babies the distending pressure was applied for hypoxaemia during the course of the disease. 16 survived without further intervention, though one case eventually required long-term continuous distending pressure (CDP) for pulmonary oedema. 11 out of the 27 required intermittent positive pressure ventilation (IPPV), with 6 survivors. In 13 other babies who had not received CDP previously, the technique was used to assist weaning from IPPV. It sustained oxygenation in each case, and 12 of these babies survived. Seven babies developed pneumothoraces and 2 babies intrapulmonary cysts. 6 babies died, 3 with pneumothoraces. The overall incidence of intraventricular haemorrhage was 3 proven and 2 suspected cases. There was no evidence that distending pressure in any form increased the incidence of intracranial haemorrhage. ImagesFIG. 4FIG. 5FIG. 6 PMID:4611351

This 2-year prospective, longitudinal, observational cohort study enrolled 29 children and adolescents. Clinical data, measurements of blood gases and ventilation parameters were collected at four different time points. Fluctuations between measurements as well as differences in estimated means were analyzed by linear mixed models in which death within 28 days from the onset of acute respiratory distress syndrome was the primary endpoint. There were 17 deaths within 28 days of acute respiratory distress syndrome onset and another 7 between 29 - 60 days. Only 5 patients survived for more than 60 days. Nine (31%) patients died as a direct consequence of refractory hypoxemia, and the others died of multiple organ failure and catecholamine-refractory shock. In 66% of the measurements, the tidal volume required to obtain oxygen saturation equal to or above 90% was greater than 7mL/kg. The estimated means of dynamic compliance were low and were similar for survivors and non-survivors but with a negative slope between the first and final measurements, accompanied by a negative slope of the tidal volume for non-survivors. Non-survivors were significantly more hypoxemic, with PaO2/FiO2 ratios showing lower estimated means and a negative slope along the four measurements. Peak, expiratory and mean airway pressures showed positive slopes in the non-survivors, who also had more metabolic acidosis. In most of our children with cancer, sepsis and acute respiratory distress syndrome progressed with deteriorating ventilation indexes and escalating organic dysfunction, making this triad nearly fatal in children.

    To provide additional details and evidence behind the recommendations for outcomes assessment of patients with pediatric acute respiratory distress syndrome from the Pediatric Acute Lung Injury Consensus Conference. Consensus conference of experts in pediatric acute lung injury. A panel of 27 experts met over the course of 2 years to develop a taxonomy to define pediatric acute respiratory distress syndrome and to make recommendations regarding treatment and research priorities. The outcomes subgroup comprised four experts. When published data were lacking, a modified Delphi approach emphasizing strong professional agreement was used. The Pediatric Acute Lung Injury Consensus Conference experts developed and voted on a total of 151 recommendations addressing the topics related to pediatric acute respiratory distress syndrome, seven of which related to outcomes after pediatric acute respiratory distress syndrome. All seven recommendations had strong agreement. Children with acute respiratory distress syndrome continue to have a high mortality, specifically, in relation to certain comorbidities and etiologies related to pediatric acute respiratory distress syndrome. Comorbid conditions, such as an immunocompromised state, increase the risk of mortality even further. Likewise, certain etiologies, such as non-pulmonary sepsis, also place children at a higher risk of mortality. Significant long-term effects were reported in adult survivors of acute respiratory distress syndrome: diminished lung function and exercise tolerance, reduced quality of life, and diminished neurocognitive function. Little knowledge of long-term outcomes exists in children who survive pediatric acute respiratory distress syndrome. Characterization of the longer term consequences of pediatric acute respiratory distress syndrome in children is vital to help identify opportunities for improved therapeutic and rehabilitative strategies that will lessen the long-term burden of pediatric acute

    Spirituality is related to many aspects of cancer survivors' physical and psychological adjustment. Given their unique developmental issues, spiritual issues may be especially important to adolescent and young adult (AYA) survivors, yet little research has been conducted on spirituality with AYA survivors. The present study examines how two aspects of spirituality, spiritual well-being (comprising faith and meaning/peace), and spiritual struggle relate to later post-cancer adjustment. At Time 1 (T1), 120 AYA survivors completed questionnaires on spirituality and adjustment (fear of recurrence, post-traumatic stress symptoms, perceived post-traumatic growth, psychological distress, and health-related quality of life). Eighty-three of these participants also completed these questionnaires at Time 2 (T2), one year later. Our sample reported fairly low spiritual well-being (meaning/peace, faith) and spiritual struggle. As expected, T1 spiritual well-being was positively correlated with some aspects of psychological adjustment at T2, whereas T1 spiritual struggle was inversely correlated with T2 psychological adjustment. Both dimensions of T1 spiritual well-being, but not struggle, were positively associated with perceived T2 posttraumatic growth. In general, T1 spiritual well-being and struggle correlated with T2 psychological adjustment even when demographics and cancer-related variables were controlled. These results suggest that while spirituality is not important to all AYA survivors, both spiritual well-being and struggle have important associations with adjustment and may warrant clinical attention. Future research is needed to more fully understand the role of spirituality in AYA survivors' adjustment in more depth. Copyright © 2016 John Wiley & Sons, Ltd.

    Acute respiratory distress syndrome is a disease of acute onset characterized by hypoxemia and infiltrates on chest radiographs that affects both adults and children of all ages. It is an important cause of respiratory failure in pediatric intensive care units and is associated with significant morbidity and mortality. Nevertheless, until recently, the definitions and diagnostic criteria for acute respiratory distress syndrome have focused on the adult population. In this article, we review the evolution of the definition of acute respiratory distress syndrome over nearly five decades, with a special focus on the new pediatric definition. We also discuss recommendations for the implementation of mechanical ventilation strategies in the treatment of acute respiratory distress syndrome in children and the use of adjuvant therapies.

    Childhood cancer survivors are thought to be at risk of psychological difficulties. We examined the prevalence of depressive symptoms and mental well-being in adult long-term survivors of childhood acute lymphoblastic leukemia (ALL) at a mean age of 20 years after the cessation of therapy. Depressive symptoms were assessed with Beck Depression Inventory (BDI-21) and mental distress with General Health Questionnaire (GHQ-12) among 73 ALL survivors and 146 healthy controls. The ALL survivors obtained significantly lower BDI scores (P=0.046) compared with the controls, indicating less depressive symptoms among the ALL survivors. BDI scores indicated a significantly less frequent moderate or severe depression in the ALL survivors compared with the controls (P=0.039). BDI scores indicated no depression in 80.8% of the ALL survivors and 73.3% of the control group. The female ALL survivors obtained lower BDI scores than did the female controls (P=0.005). No difference was found in GHQ-12 scores between the survivors and the controls. Survivors of ALL reported fewer depressive symptoms and equal mental well-being compared with healthy controls. Our findings support the idea that childhood leukemia survivors' subjective experience of well-being is possibly affected by repressive adaptive style.

    The authors evaluated the clinical and physiological effects of kinetic therapy (KT) in the treatment of acute respiratory distress syndrome (ARDS). Forty-six patients with ARDS underwent successive postural positioning in accordance with two regimens: 1) lateral, prone, contralateral, supine positions; 2) prone, lateral, contralateral, supine positions. The criterion for changing each position was the change in monitoring indices: SpO2, PaO2, and thoracopulmonary compliance (C). KT was performed until a respirator was withdrawn from the patient. In 25 patients, each maneuver of positioning was made during 30-minute propofol sedation. The control group included 24 patients with ARDS who received neither KT nor propofol sedation. KT caused a decrease in Vd/Vt, Qs/Qt and an increase in PaO2/FiO2 and C was more intensive, as compared with the control group. The duration of the patient's prone position was 3.2-0.7 hours and that of the supine position was 3.4-0.8 hours. The right and left lateral positions lasted 1.1-0.2 and 1.3-0.2 hours, respectively. KT regimen 1 was found to be more effective than KT regimen 2. Propofol sedation enhanced the efficiency of KT. The latter reduced death rates in patients with ARDS.

    This review discusses the role of chest ultrasound in diagnosis and management of acute respiratory distress syndrome (ARDS) and the most recent technical progresses in this field. Clinically, suspected ARDS can be easily confirmed by lung ultrasonography through the recognition of a typical pattern characterized by B-lines, spared areas, pleural line thickening, and subpleural consolidations. A visual score based on number and thickness of B-lines permits a semiquantitative evaluation of the amount of extravascular lung water and lung density. Recently, a quantitative lung ultrasound method has been proposed. The heart may be also involved in ARDS either primarily or by the application of positive pressure ventilation. The incidence of acute cor pulmonale during ARDS is, even if under protective ventilation, not negligible. The use of echocardiography combined with lung ultrasound is important for early detection of cor pulmonale, identification of the best ventilator strategy to preserve heart-to-lung interaction, and prediction of weaning success. An ultrasound-integrated approach combining lung ultrasound and echocardiography should be recommended as a suitable technique to manage ARDS during diagnosis, mechanical ventilation setting, and weaning.

    Imaging has become increasingly important across medical specialties for diagnostic, monitoring, and investigative purposes in acute respiratory distress syndrome (ARDS). This review addresses the use of imaging techniques for the diagnosis and management of ARDS as well as gaining knowledge about its pathogenesis and pathophysiology. The techniques described in this article are computed tomography, positron emission tomography, and two easily accessible imaging techniques available at the bedside-ultrasound and electrical impedance tomography (EIT). The use of computed tomography has provided new insights into ARDS pathophysiology, demonstrating that ARDS does not homogeneously affect the lung parenchyma and that lung injury severity is widely distributed in the ARDS population. Positron emission tomography is a functional imaging technique whose value resides in adding incremental insights to morphological imaging. It can quantify regional perfusion, ventilation, aeration, lung vascular permeability, edema, and inflammation. Lung ultrasound and EIT are radiation-free, noninvasive tools available at the bedside. Lung ultrasound can provide useful information on ARDS diagnosis when x-rays or CT scan are not available. EIT is a useful tool to monitor lung ventilation and to assess the regional distribution of perfusion. The future of imaging in critical care will probably develop in two main directions: easily accessible imaging techniques that can be used at the bedside and sophisticated imaging methods that will be used to aid in difficult diagnostic cases or to advance our understanding of the pathogenesis and pathophysiology of an array of critical illnesses.

    Acute respiratory distress syndrome (ARDS) was first described about 30 years ago. Modern definitions and statements have recently been proposed to describe ARDS accurately, but none is perfect. Diffuse alveolar damage is the basic pathological pattern most commonly observed in ARDS, and the term includes permeability edema. The alveolar epithelium of the alveolar-capillary barrier is clearly a key component requiring repair, given its multipotent functional activity. Lung inflammation and neutrophil accumulation are essential markers of disease in ARDS, and a wide variety of pro- and anti-inflammatory cytokines have been described in the alveolar fluid and blood of patients. These molecules still have to prove their value as diagnostic or prognostic biomarkers of ARDS. Supportive therapy in ARDS improved in the past decade; mechanical ventilation with lung protective strategies and patient positioning are gaining interest, but the indications for corticosteroids for ARDS are still debated. Nitric oxide may have a place in the treatment of one-third of patients. Novel approaches, such as surfactant replacement and liquid ventilation, may further improve supportive therapy. Innovative interventions may be on the horizon in treatments that help to resolve or modulate common pathways of ARDS, such as inflammation (eg, granulocyte-colony stimulating factor) or epithelial repair (eg, keratinocyte growth factor).

    The acute respiratory distress syndrome (ARDS) encountered in a child may be either due to a primary lung infection or may be secondary to a systemic inflammatory response of varying origin. Therapy is based on: 1) the mechanical ventilation strategy aimed at maintaining the functional residual capacity by alveolar recruitment using positive end expiratory pressure and to limit secondary pulmonary lesions by using small tidal volumes, 2) prone positioning as soon as sufficient stability is achieved; 3) optimizing tissue oxygen delivery by cardiac support; 4) correction of any other organ dysfunction. If this conventional approach is not sufficient experimental therapies may be tempted given the vital risk. For instance inhaled nitric oxide and high frequency oscillation ventilation may be a valuable support. Newer techniques, such as partial liquid ventilation, are being developed and could become useful therapeutic options. After the acute phase a close medical follow-up is mandatory. Because of the possibility of a chronic respiratory insufficiency with negative consequences on the right ventricular function, these patients may need long term oxygen therapy and diuretics. Cardiac echography helps orientation in maintaining or discontinuing this long term therapy by estimating the arterial pulmonary pressure.

    The number of childhood cancer survivors is increasing as survival rates improve. However, complications after treatment have not received much attention, particularly metabolic syndrome. Metabolic syndrome comprises central obesity, dyslipidemia, hypertension, and insulin resistance, and cancer survivors have higher risks of cardiovascular events compared with the general population. The mechanism by which cancer treatment induces metabolic syndrome is unclear. However, its pathophysiology can be categorized based on the cancer treatment type administered. Brain surgery or radiotherapy may induce metabolic syndrome by damaging the hypothalamic-pituitary axis, which may induce pituitary hormone deficiencies. Local therapy administered to particular endocrine organs directly damages the organs and causes hormone deficiencies, which induce obesity and dyslipidemia leading to metabolic syndrome. Chemotherapeutic agents interfere with cell generation and growth, damage the vascular endothelial cells, and increase the cardiovascular risk. Moreover, chemotherapeutic agents induce oxidative stress, which also induces metabolic syndrome. Physical inactivity caused by cancer treatment or the cancer itself, dietary restrictions, and the frequent use of antibiotics may also be risk factors for metabolic syndrome. Since childhood cancer survivors with metabolic syndrome have higher risks of cardiovascular events at an earlier age, early interventions should be considered. The optimal timing of interventions and drug use has not been established, but lifestyle modifications and exercise interventions that begin during cancer treatment might be beneficial and tailored education and interventions that account for individual patients' circumstances are needed. This review evaluates the recent literature that describes metabolic syndrome in cancer survivors, with a focus on its pathophysiology.

    Studies in animals and in vitro and phase 2 studies in humans suggest that statins may be beneficial in the treatment of the acute respiratory distress syndrome (ARDS). This study tested the hypothesis that treatment with simvastatin would improve clinical outcomes in patients with ARDS. In this multicenter, double-blind clinical trial, we randomly assigned (in a 1:1 ratio) patients with an onset of ARDS within the previous 48 hours to receive enteral simvastatin at a dose of 80 mg or placebo once daily for a maximum of 28 days. The primary outcome was the number of ventilator-free days to day 28. Secondary outcomes included the number of days free of nonpulmonary organ failure to day 28, mortality at 28 days, and safety. The study recruited 540 patients, with 259 patients assigned to simvastatin and 281 to placebo. The groups were well matched with respect to demographic and baseline physiological variables. There was no significant difference between the study groups in the mean (±SD) number of ventilator-free days (12.6±9.9 with simvastatin and 11.5±10.4 with placebo, P=0.21) or days free of nonpulmonary organ failure (19.4±11.1 and 17.8±11.7, respectively; P=0.11) or in mortality at 28 days (22.0% and 26.8%, respectively; P=0.23). There was no significant difference between the two groups in the incidence of serious adverse events related to the study drug. Simvastatin therapy, although safe and associated with minimal adverse effects, did not improve clinical outcomes in patients with ARDS.

    Recent guidelines recommend to assess emotional distress in pediatric oncology during treatment and in after care. One tool used to do this is the distress thermometer (DT), a simple tool which has almost exclusively been studied in its screening abilities. Given its increased used as a measure of distress per se, it is necessary to document its concurrent validity. The goal of this study was to identify clinical domains (eg, depression, anxiety) and individual symptoms associated with pediatric cancer survivors' rating on the DT. To do so we used data collected from 84 young (≤18 years old), and 120 older (>18 years old) survivors who were treated for pediatric leukemia. Participants responded to self-report questionnaires as part of a research visit. Results from stepwise regressions show that in the younger group, high scores on the thermometer were associated with higher negative affectivity only. In adults, high scores were associated with higher anxiety, higher negative affectivity, and lower positive affectivity. When exploring associations with individual items, we found that the main emotional tone reflected by the thermometer score was anxiety. Interpreting ratings on the thermometer should probably focus on anxiety in childhood cancer survivors. This widely used tool also does not measure the same domains in young versus older survivors, so that age groups should be considered separately in future work.

    A consequence of the West Africa Ebola outbreak 2014-2015 was the unprecedented number of Ebola survivors discharged from the Ebola Treatment Units (ETUs). Liberia alone counted over 5,000 survivors. We undertook a qualitative study in Monrovia to better understand the mental distress experienced by survivors during hospitalization and reintegration into their community. Purposively selected Ebola survivors from ELWA3, the largest ETU in Liberia, were invited to join focus group discussions. Verbal-informed consent was sought. Three focus groups with a total of 17 participants were conducted between February and April 2015. Thematic analysis approach was applied to analyze the data. The main stressors inside the ETU were the daily exposure to corpses, which often remained several hours among the living; the patients' isolation from their families and worries about their well-being; and sometimes, the perception of disrespect by ETU staff. However, most survivors reported how staff motivated patients to drink, eat, bathe, and walk. Additionally, employing survivors as staff fostered hope, calling patients by their name increased confidence and familiarity, and organizing prayer and singing activities brought comfort. When Ebola virus disease survivors returned home, the experience of being alive was both a gift and a burden. Flashbacks were common among survivors. Perceived as contagious, many were excluded from their family, professional, and social life. Some survivors faced divorce, were driven out of their houses, or lost their jobs. The subsequent isolation prevented survivors from picking up daily life, and the multiple losses affected their coping mechanisms. However, when available, the support of family, friends, and prayer enabled survivors to cope with their mental distress. For those excluded from society, psychosocial counseling and the survivor's network were ways to give a meaning to life post-Ebola. Exposure to death in the ETU and stigma in the

    Acute respiratory distress syndrome is associated with poor clinical outcomes with a pooled mortality rate of approximately 40% despite best standards of care. Current therapeutic strategies are based upon improving oxygenation and pulmonary compliance while minimizing ventilator induced lung injury. It has been demonstrated that relative hypoxemia can be well tolerated and improvements in oxygenation do not necessarily translate into survival benefit. Cardiac failure, in particular right ventricular dysfunction, is commonly encountered in moderate to severe acute respiratory distress syndrome and is reported to be one of the major determinants of mortality. The prevalence rate of echocardiographically evident right ventricular dysfunction in acute respiratory distress syndrome varies across studies ranging from 22% to 50%. Although there is no definitive causal relationship between right ventricular dysfunction and mortality, severe right ventricular dysfunction is associated with increased mortality. Factors that can adversely affect right ventricular function include hypoxic pulmonary vasoconstriction, hypercapnia, and invasive ventilation with high driving pressure. It might be expected that early diagnosis of right ventricular dysfunction would be of benefit however, echocardiography markers (qualitative and quantitative) used to prospectively evaluate the right ventricle in acute respiratory distress syndrome have not been tested in adequately powered studies. In this review we examine the prognostic implications and pathophysiology of right ventricular dysfunction in acute respiratory distress syndrome and discuss available diagnostic modalities and treatment options. We aim to identify gaps in knowledge and directions for future research that could potentially improve clinical outcomes in this patient population.

    Mortality in Acute Respiratory Distress Syndrome (ARDS) is decreasing, although its prognosis after hospital discharge and the prognostic accuracy of Berlin's new ARDS stratification are uncertain. We did a restrospective analysis of hospital and 6 month mortality of patients with ARDS admitted to the Intensive Care Unit of a Univeristy Hospital in Buenos Aires, between January 2008 and June 2011. ARDS was defined by PaO2/FiO2 lower than 200 mmHg under ventilation with at least 10 cm H2O of PEEP and a FiO2 higher or equal than 0.5. and the presence of bilateral infiltrates in chest radiography, in the absence of cardiogenic acute pulmonary edema, during the first 72 hs of mechanical ventilation. Mortality associated risk factors, the use of rescue therapies and Berlin's stratification for moderate and severe ARDS patients were considered. Ninety eight patients were included; mean age was 59±19 years old, 42,9% had mayor co-morbidities; APACHE II at admission was 22±7; SOFA at day 1 was 8±3. Prone position ventilation was applied in 20,4% and rescue measures in 12,2% (12 patients with nitric oxide and 1 with extracorporeal membrane oxygenation). Hospital and 6 months mortality were 37.7 and 43.8% respectively. After logistic regression analysis, only age, the presence of septic shock at admission, Ppl >30 cmH2O, and major co-morbidities were independently associated with hospital outcome. There was no difference between moderate and severe groups (41,2 and 36,8% respectively; p=0,25). In this cohort, including patients with severe hypoxemia and high percentage of mayor co-morbidities, ARDS associated mortality was lower than some previous studies. There was no increase in mortality after hospital discharge. There was no difference in mortality between moderate and severe groups according to Berlin's definition.

    This article examines how the personal experiences of mental distress of people involved in the British service user/survivor movement were shaped or transformed by this involvement, and the impact of involvement on their recovery journeys. The analysis was based on 12 in-depth interviews with service users/survivors who are, or were once, involved with the service user/survivor movement. Three large themes were identified regarding the ways in which social movement involvement affected the personal experience of mental distress: (a) making sense and reframing mental distress, (b) the social experience of involvement and (c) identity and identity reconstruction. We discuss how some features of the service user/survivor movement, such as self-help, user involvement, the centrality of experience to collective action, and the range of political positions adopted by activists can affect experience and recovery in different forms. As an exploratory study that looks into a complex topic, our findings illuminate the ways of surviving, recovering and experiencing mental distress in the context of a significant social movement. © The Author(s) 2014.

    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.

    Outcomes after acute respiratory distress syndrome (ARDS) are similar to those of other survivors of critical illness and largely affect the nerve, muscle, and central nervous system but also include a constellation of varied physical devastations ranging from contractures and frozen joints to tooth loss and cosmesis. Compromised quality of life is related to a spectrum of impairment of physical, social, emotional, and neurocognitive function and to a much lesser extent discrete pulmonary disability. Intensive care unit-acquired weakness (ICUAW) is ubiquitous and includes contributions from both critical illness polyneuropathy and myopathy, and recovery from these lesions may be incomplete at 5 years after ICU discharge. Cognitive impairment in ARDS survivors ranges from 70 to 100 % at hospital discharge, 46 to 80 % at 1 year, and 20 % at 5 years, and mood disorders including depression and post-traumatic stress disorder (PTSD) are also sustained and prevalent. Robust multidisciplinary and longitudinal interventions that improve these outcomes are still uncertain and data in our literature are conflicting. Studies are needed in family members of ARDS survivors to better understand long-term outcomes of the post-ICU family syndrome and to evaluate how it affects patient recovery.

    Relatively few studies focus on the psychological effects of trauma exposure on Asian Americans. This article presents secondary analyses of a random survey of 118 Asian American and 762 European American survivors of the 1994 Northridge, California earthquake. Asian American participants reported more psychiatric distress and were more than twice as likely to meet caseness criteria on the Brief Symptom Inventory. Ethnic differences remained after accounting for group differences in age, immigrant status, and exposure to the earthquake. Moreover, moderator analyses showed that Asian Americans were not more sensitive to these risk factors but that ethnic differences were explained by the interaction of ethnicity and having a foreign born parent. Though more work needs to be done to understand the basis of these differences, these findings challenge model minority myths about Asian American people and draw attention to their potential need for greater mental health resources following a natural disaster.

He began to produce bloodstained sputum and was found to have severe arterial hypoxaemia. Radiography showed widespread opacification over both lung fields, and the clinical and haemodynamic features were consistent with the adult respiratory distress syndrome. Serology for Leptospira canicola was positive. Despite antibiotics, supportive therapy, and ventilation the patient died. Necropsy excluded cardiac disease. This case shows that leptospirosis may cause the adult respiratory distress syndrome. Images p520-a PMID:6790049

    Background The long-term psychological impact of pediatric sarcoma is largely unknown. As part of a cross-sectional study examining the late effects of pediatric sarcoma therapy, we examined whether psychological distress or posttraumatic stress symptoms are present in an adult cohort of pediatric sarcoma survivors. Method Thirty-four patients participated in the study, an average of 17 years after their treatment ended, each completing the SCID module for Posttraumatic Stress Disorder, Impact of Events Scale, Brief Symptom Inventory (BSI) and a questionnaire assessing sociodemographic variables and psychosocial issues. Results Significant persistent psychological distress characterized this cohort of patients. Seventy-seven percent scored in the clinical range on the BSI. Twelve percent met diagnostic criteria for PTSD. Current psychological distress was associated with intrusive thoughts and avoidant behaviors, male gender, employment, difficulty readjusting to work/school after treatment, and enduring worries about health. No differences were found based on age, presence of metastatic disease or time since diagnosis. Conclusions This is the first report of a clinical evaluation of psychological distress in a cohort of pediatric sarcoma survivors treated with intensive multimodal cancer therapy. The results suggest that survivors of pediatric sarcoma might be at high risk for adverse psychological outcomes. Appropriate interventions are proposed. PMID:16402373

    This study focuses on the effect of chemotherapy on endocrinopathies and the metabolic syndrome in adult survivors of childhood acute myeloid leukemia (AML). Endocrine function and metabolic syndrome were evaluated in 12 AML survivors, treated with chemotherapy, and in 9 survivors of myeloid leukemias treated with stem cell transplantation (SCT), after a median follow-up time of 20 years (range 9-31). In survivors treated with chemotherapy, no endocrinopathies or metabolic syndrome were present, although AMH and Inhibin B levels tended to be lower than in controls. In SCT survivors, pituitary deficiencies and metabolic syndrome were more frequent. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Treatment-related obesity and the metabolic syndrome in adult survivors of childhood acute lymphoblastic leukemia (ALL) are risk factors for cardiovascular disease. Both conditions often begin during therapy. Preventive measures, including dietary counseling and tailored exercise, should be initiated early in the course of survivorship, with referral to specialists to optimize success. However, among adults who develop obesity or the metabolic syndrome and who do not respond to lifestyle therapy, medical intervention may be indicated to manage underlying pathology, such as growth hormone deficiency, or to mitigate risk factors of cardiovascular disease. Because no specific clinical trials have been done in this population to treat metabolic syndrome or its components, clinicians who follow adult survivors of childhood ALL should use the existing American Heart Association/National Heart Lung and Blood Institute Scientific Statement to guide their approach.

    In prior community studies survivors of the Shoa (Hebrew for Holocaust) scored higher on emotional distress (ED) than Europe-born Jews who were not in Nazi-occupied countries during World War II (WWII). Are elderly Shoa survivors, who by definition have survived the difficulties of a long life, equally distressed? ED was assessed among a population of elderly survivors living in the community, about 55 years after the end of WWII. ED was also examined by the severity of exposure to adverse life conditions during the war. In addition, other health-related dimensions, e.g., sleep disturbances and social activities, were measured. A national survey of 5,055 respondents, of whom 4,231 were Jewish-Israelis, was conducted among community residents aged 60 years and over. The research population included former residents of Nazi-occupied countries (N=896). This group was compared with Europe- and America-born individuals who resided elsewhere during WWII (N=331). All respondents were administered, among many other items, the 12-GHQ to measure ED and a questionnaire that included socio-demographic and other health-related variables. Bivariate and multivariate methods of analysis were used to compare distributions and to identify relevant factors. The group of elderly survivors was significantly more distressed than the comparison group. Individuals who had been in ghettos, hiding, or labor or extermination camps had higher mean scores than survivors who were in Nazi-occupied countries, but were spared those experiences. Multivariate analysis showed that the direct effect of the Shoa experience was no longer evident when two other Shoa-dependent variables, years of education and number of chronic health conditions, were entered into the model. Sleep disturbances were more often present in the survivors than among their counterparts, including after controlling for other variables. Social activities that contribute to well-being were more limited among survivors. Fifty years

    The current study was performed to examine associations between childhood cancer therapies, chronic health conditions, and symptoms of emotional distress in adult survivors of childhood cancer. Participants included 5021 adult survivors of childhood cancer (mean age, 32.0 years [standard deviation, 7.6 years] with a time since diagnosis of 23.2 years [standard deviation, 4.5 years]) who completed measures assessing symptoms of anxiety, depression, and posttraumatic stress. Cardiac, pulmonary, and endocrine conditions were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03; grades 1-4). Structural equation modeling was used to examine hypothesized pathways between cancer treatment exposures, chronic health conditions, and symptoms of emotional distress. Multivariable models were used to estimate relative risks (RRs) for associations between chronic health conditions and distress. Survivors with cardiovascular, endocrine, or pulmonary conditions were found to have a significantly higher prevalence of emotional distress symptoms. In path analyses and multivariable models, significant effects were observed between endocrine (β = .12 [P = .002] and RR, 1.3 [95% confidence interval (95% CI), 1.1-1.6]) and pulmonary (β = .13 [P<.001] and RR, 1.4 [95% CI, 1.1-1.7]) conditions and depression, and between cardiac (β = .13 [P = .001] and RR, 1.5 [95% CI, 1.2-1.8]) and pulmonary (β = .15 [P<.001] and RR, 1.6 [95% CI, 1.3-2.0]) conditions and anxiety. All treatment-related chronic health conditions were found to be associated with posttraumatic stress symptoms (cardiac: β = .09 [P = .004] and RR, 1.3 [95% CI, 1.2-1.5]; endocrine: β = .12 [P<.001] and RR, 1.3 [95% CI, 1.2-1.5]; and pulmonary: β = .13 [P<.001] and RR, 1.4 [95% CI, 1.2-1.6]).

    The primary aim was to determine the efficacy of the Distress Thermometer (DT) in screening for anxiety and mood problems against the University of Washington Quality of Life, version 4 (UWQOL). Secondary aims were to evaluate the association between demographic, clinical and health-related QOL variables with significant distress. Two hundred and sixty one disease-free HNC ambulatory patients attending routine follow-up clinics were prospectively recruited. Both DT and UWQOL were completed pre-consultation. Receiver operating characteristic (ROC) curve analyses of DT score for anxiety dysfunction yielded an area under the curve (AUC) of 0.877, with a sensitivity of 84% (43/51) and specificity of 76% (159/210) for a DT cut-off of ≥4; with a corresponding AUC of 0.825 for mood with sensitivity 78% (28/36) and specificity 71% (159/225). Treatment with radiotherapy and a longer consultation time were associated with significant distress (DT ≥4). Significant distress was also reported in two third of those reporting less than "Good" overall QOL. Distress levels were particularly associated with poor Social-Emotional function, more so than the association seen with poor physical function. DT is a reasonable screening tool for distress in the HNC population. The DT cut-off score ≥4 was effective in identifying those with significant distress. Significant distress is associated in survivors with poor health-related quality of life, those who received radiotherapy and patients who have longer consultation times in clinic.

    To investigate the relationships between sociodemographic, pre- and post-migration variables with prevalence of psychological distress and global functioning in a heterogeneous sample of torture survivors. Clients referred from resettlement agencies via the Office of Refugee Resettlement (ORR) to a community clinic in the United States (N = 278) were interviewed with structured, translated questionnaires. Univariate and multivariate logistic regression analyses determined the associations of sociodemographic, pre-, and post-migration risk factors with posttraumatic stress disorder (PTSD), depression, anxiety, and global functioning. Regression data indicate that length of time between arrival in US and clinical services was significantly associated with PTSD and depression; participants receiving services after 1 year of resettlement were more likely to experience PTSD (adjusted OR = 3.29) and depression (adjusted OR = 4.50) than participants receiving services within 1 year. Anxiety was predicted by female gender (adjusted OR = 3.43), age over 40 years (adjusted OR = 3.12), Muslim religion (adjusted OR = 2.64), and receiving medical services (AOR 3.1). Severely impaired global functioning was associated with female gender (adjusted OR = 2.75) and unstable housing status (adjusted OR = 2.21). Findings highlight the importance of examining post-migration variables such as length of time in country prior to receiving services in addition to pre-migration torture history upon relocated torture survivors. Clinicians and policy-makers should be aware of the importance of early mental health screening and intervention on reducing the psychiatric burden associated with torture and forced relocation.

    Purpose Long-term survivors of childhood cancer appear to have an increased risk for the metabolic syndrome, subsequent type 2 diabetes and cardiovascular disease in adulthood compared to healthy children. The purpose of this study was to investigate the frequency of the metabolic syndrome and associated factors in childhood cancer survivors at a single center in Korea. Methods We performed a retrospective review of medical records of 98 childhood cancer survivors who were diagnosed and completed anticancer treatment at Samsung Medical Center, Seoul, Korea between Jan. 1996 and Dec. 2007. Parameters of metabolic syndrome were evaluated between Jan. 2008 and Dec. 2009. Clinical and biochemical findings including body fat percentage were analyzed. Results A total of 19 (19.4%) patients had the metabolic syndrome. The median body fat percentage was 31.5%. The body mass index and waist circumference were positively correlated with the cranial irradiation dose (r=0.38, P<0.001 and r=0.44, P<0.00, respectively). Sixty-one (62.2%) patients had at least one abnormal lipid value. The triglyceride showed significant positive correlation with the body fat percentage (r=0.26, P=0.03). The high density lipoprotein cholesterol showed significant negative correlation with the percent body fat (r=-0.26, P=0.03). Conclusion Childhood cancer survivors should have thorough metabolic evaluation including measurement of body fat percentage even if they are not obese. A better understanding of the determinants of the metabolic syndrome during adolescence might provide preventive interventions for improving health outcomes in adulthood. PMID:21949520

    To assess the levels of psychological distress and identify predictors of anxiety/depression caseness after cancer cure, a national population of 557 Hodgkin's disease (HD) survivors was surveyed. The respondents [204 women, 255 men, mean age 44 years (SD = 12)] returned a mailed questionnaire including The Hospital Anxiety and Depression Scale (HADS). Disease and treatment variables were based on the hospital records. A total of 27% had caseness scores (anxiety, 14.5%; depression, 4%; anxiety and depression, 8.5%). In a multiple logistic regression analysis, anxiety caseness was predicted by low educational status [OR (odds ratio) = 2.07, 95% CI = 1.02-4.22], observational period 7 years or longer (7-10 years: OR = 3.07, 95% CI = 1.26-7.47), combined irradiation and chemotherapy treatment (OR = 2.77, 95% CI = 1.17-6.54) and psychiatric symptoms before HD (OR = 2.55, 95% CI = 1.40-4.65) or during treatment (OR = 3.51, 95% CI = 2.08-5.90). Depression caseness was predicted by age (OR = 1.03, 95% CI = 1.00-1.06) and psychiatric symptoms before HD (OR = 5.1, 95% CI = 2.55-10.31) Anxiety cases are more prevalent than in the general Norwegian population, and were found to be most common 7-10 years after treatment. The most intensive treatment was associated with increased risk for anxiety caseness. The subjects experienced distress during treatment precedes difficulties in long-term adjustment. Focusing on these predictors during treatment and follow-up controls may improve long-term outcome. PMID:9310248

    Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position. This method, first recommended to improve oxygenation in 1974, can be easily implemented in any intensive care unit with trained personnel. Prone position has extremely robust bibliographic support. Various randomized clinical studies have demonstrated the effect of prone decubitus on the oxygenation of patients with acute respiratory distress syndrome measured in terms of the PaO2/FiO2 ratio, including its effects on increasing patient survival. The members of the Respiratory Therapists Committee of the Sociedad Argentina de Terapia Intensiva performed a narrative review with the objective of discovering the available evidence related to the implementation of prone position, changes produced in the respiratory system due to the application of this maneuver, and its impact on mortality. Finally, guidelines are suggested for decision-making.

    Disaster studies of the effects of trauma exposure on subsequent psychological health have seldom used population comparisons. A total of 1463 tsunami survivors from Stockholm were categorized according to type of exposure, and compared on measures of General Health Questionnaire and sick leave, with a matched population-based sample of 12,045 individuals from the same region. Data from the survivor group were obtained through a postal questionnaire 14 months postdisaster. Data from the population sample were collected in the same year. In comparison to the population sample, levels of sick leave ranged from higher in multiply exposed groups to lower in the least exposed group. For psychological distress, levels in multiply and moderately exposed groups were higher, and in lower exposed groups comparable. The use of a population comparison resulted in a support of recent research showing a relative resiliency of survivors exposed during disaster to potential trauma of lesser severity.

    Most survivors of ARDS have persistent mild reductions of TLCO even as long as a year after their episode. The lung volumes and flows return to normal in most instances, although a subset of patients will have persistent impairment. Both obstructive and restrictive deficits may be seen. This group may be predicted by the degree of acute lung injury assessed by the level of FIO2, PEEP, and gas exchange abnormality that exists in the first few days. In the first year after ARDS most physiological abnormalities will improve, but if deficits persist at one year further improvement is unlikely. Although many patients report dyspnoea following ARDS, the symptom does not correlate with abnormalities of pulmonary function. The possibility that conventional management may augment the degree of acute injury and worsen outcome must be considered. The effects of chronic hyperoxia in humans with acute lung injury or those of high levels of PEEP compared with low levels are not known. Exploring new ventilator management strategies while we await more specific treatment directed at the primary problem of acute lung inflammation will hopefully reduce acute mortality as well as acute and chronic morbidity.

    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).

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

    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.

    To examine the potential mediating role of body image dissatisfaction on the association between treatment-related scarring/disfigurement and psychological distress in adult survivors of childhood cancer. Participants included 1714 adult survivors of childhood cancer (mean [SD] age at evaluation = 32.4 [8.0] years, time since diagnosis = 24.1 [8.1] years) enrolled in the St. Jude Lifetime Cohort Study. Survivors completed measures of body image, emotional distress, and posttraumatic stress symptoms (PTSS). Body image dissatisfaction (BID) was categorized into 2 groups (cancer-related and general) based on factor analysis. Using causal mediation analysis, we estimated the proportion of psychological distress associated with treatment-related scarring/disfigurement that could be eliminated by resolving BID through a hypothetical intervention. Among survivors with scarring/disfigurement of the head, a sizable proportion of the relative excess of psychological distress could be eliminated if BID was successfully treated (males: [cancer-related BID: depression: 63%; anxiety: 100%; PTSS: 52%]; [general BID: depression: 70%; anxiety: 100%; PTSS: 42%]; females: [cancer-related BID: depression: 20%; anxiety; 36%; PTSS: 23%]; [general BID: depression: 32%; anxiety: 87%; PTSS: 38%]). The mediating effect of BID was less pronounced for the association between scarring/disfigurement of the body and psychological distress for both males and females. Body image dissatisfaction mediates the association treatment-related scarring/disfigurement and psychological distress among adult survivors of childhood cancer, particularly among survivors with scarring/disfigurement of the head and male survivors. Successful treatment of body image dissatisfaction has the potential to eliminate a substantial proportion of psychological distress related to scarring/disfigurement among adult survivors of childhood cancer.

    The current study examined the prevalence and correlates of somatic distress (SD) in the aftermath of war, and the role of a process hypothesized to contribute to posttraumatic stress: experiential avoidance. Civilian war survivors (n = 163) from Kosovo were assessed in structured interviews, reporting on average more than ten types of traumatic war exposure. One in eight (12.9%) of the participants meet criteria for SD, which was associated with greater psychological distress, experiential avoidance, and lower quality of life after accounting for the effects of war-related variables, demographic variables, as well as posttraumatic stress disorder and major depressive episode. Experiential avoidance partially mediated the association between SD and psychological distress and quality of life. The results indicate that SD is prevalent among war-exposed civilians and that experiential avoidance may be a significant factor in understanding and treating traumatized people who are experiencing SD.

    Objective Physiologic dead space is associated with mortality in acute respiratory distress syndrome (ARDS), but its measurement is cumbersome. Alveolar dead space fraction (AVDSf) relies on the difference between arterial and end-tidal carbon dioxide (AVDSf = (PaCO2 − PETCO2)/PaCO2). We aimed to assess the relationship between AVDSf and mortality in a cohort of children meeting criteria for ARDS (both Berlin 2012 and AECC 1994 acute lung injury) and pediatric ARDS (PARDS, as defined by PALICC in 2015). Design Secondary analysis of a prospective, observational cohort. Setting Tertiary care, university affiliated pediatric intensive care unit. Patients Invasively ventilated children with PARDS. Interventions None. Measurements and Main Results Of the 283 children with PARDS, 266 had available PETCO2. AVDSf was lower in survivors (median 0.13 [IQR 0.06, 0.23]) than non-survivors (0.31 [0.19, 0.42], p < 0.001) at PARDS onset, but not 24 hours after (survivors 0.12 [0.06, 0.18], non-survivors 0.14 [0.06, 0.25], p=0.430). AVDSf at PARDS onset discriminated mortality with an area under receiver operating characteristic curve of 0.76 (95% CI 0.66–0.85, p < 0.001), better than either initial oxygenation index or PaO2/FIO2. In multivariate analysis, AVDSf at PARDS onset was independently associated with mortality, after adjustment for including severity of illness, immunocompromised status, and organ failures. Conclusions AVDSf at PARDS onset discriminates mortality, and is independently associated with non-survival. AVDSf represents a single, useful, readily obtained clinical biomarker reflective of pulmonary and non-pulmonary variables associated with mortality. PMID:26669646

    Scrub typhus is a major infectious threat in the Asia-Pacific region. We report an unusual case of scrub typhus in a patient in Singapore who presented with sepsis and acute respiratory distress syndrome but lacked the pathognomonic eschar. The patient recovered after appropriate diagnosis and doxycycline treatment. Rickettsial diseases should be included in the differential diagnosis of febrile illnesses in regions where the diseases are endemic, and absence of eschar should not be the criterion used to rule out scrub typhus.

    Pulmonary complications are common following hematopoietic stem cell transplantation. Numerous idiopathic post-transplantation pulmonary syndromes have been described. Patients at the severe end of this spectrum may present with hypoxemic respiratory failure and pulmonary infiltrates, meeting criteria for acute respiratory distress syndrome. The incidence and outcomes of acute respiratory distress syndrome in this setting are poorly characterized. Retrospective cohort study. Mayo Clinic, Rochester, MN. Patients undergoing autologous and allogeneic hematopoietic stem cell transplantation between January 1, 2005, and December 31, 2012. None. Patients were screened for acute respiratory distress syndrome development within 1 year of hematopoietic stem cell transplantation. Acute respiratory distress syndrome adjudication was performed in accordance with the 2012 Berlin criteria. In total, 133 cases of acute respiratory distress syndrome developed in 2,635 patients undergoing hematopoietic stem cell transplantation (5.0%). Acute respiratory distress syndrome developed in 75 patients (15.6%) undergoing allogeneic hematopoietic stem cell transplantation and 58 patients (2.7%) undergoing autologous hematopoietic stem cell transplantation. Median time to acute respiratory distress syndrome development was 55.4 days (interquartile range, 15.1-139 d) in allogeneic hematopoietic stem cell transplantation and 14.2 days (interquartile range, 10.5-124 d) in autologous hematopoietic stem cell transplantation. Twenty-eight-day mortality was 46.6%. At 12 months following hematopoietic stem cell transplantation, 89 patients (66.9%) who developed acute respiratory distress syndrome had died. Only 7 of 133 acute respiratory distress syndrome cases met criteria for engraftment syndrome and 15 for diffuse alveolar hemorrhage. Acute respiratory distress syndrome is a frequent complication following hematopoietic stem cell transplantation, dramatically influencing patient

    This study examined the association between social support and smoking status among adult cancer survivors, with special emphasis on mental health differences using data from 10 US states. Cross-sectional data from the 2010 Behavioral Risk Factor Surveillance System, Cancer Survivorship module on 8055 cancer survivors were analyzed. Sample weights were applied for the generalization of results to 2.6 million cancer survivors. In 2010, 15.6 % (418,700) were current, 38.4 % (1.03 million) former, and 46.0 % (1.2 million) never smokers. About 18.0 % of cancer survivors reported receiving the lowest level of social support and 12.1 % reported experiencing frequent mental distress in the past 30 days. Participants' mean age at the time of the first cancer diagnosis was 51.0 (standard error (SE) = 0.33) and mean time since their diagnosis was 11.3 years (SE = 0.18). Compared to those with infrequent mental distress, cancer survivors with frequent mental distress were diagnosed at a younger age (45.0 vs. 51.8), more likely to be current smokers (36.8 vs. 12.7 %), and less likely to always receive social support they needed (33.4 vs. 56.3 %). Cancer survivors who received higher levels of social support were less likely to be current smokers than those who received the lowest level of social support they needed. Among cancer survivors who reported frequent mental distress, non-Hispanic blacks were more likely to be current smokers than non-Hispanic whites. Rates of current smokers were lower among cancer survivors who received social support and reported infrequent mental distress. Psychosocial screening may help health care professional identify smokers with frequent mental distress who require more intensive smoking cessation interventions.

    Significant advances have occurred in the knowledge of the pathogenesis of ARDS. It is now recognized that ARDS is a manifestation of a diffuse process that results from a complicated cascade of events following an initial insult or injury. Mechanical ventilation and PEEP are still important components of supportive therapy. To avoid ventilator-associated lung injury there is emphasis on targeting ventilator management based on measurement of pulmonary mechanics. For those with resistant hypoxia and severe pulmonary hypertension adjunctive modalities, such as prone positioning and low-dose iNO, may provide important benefit. Alternative modes of supporting gas exchange, such as with partial liquid ventilation and extracorporeal gas-exchange, may serve as rescue therapies. Advances in cell and molecular biology have contributed to a better understanding of the role of inflammatory cells and mediators that contribute to the acute lung injury and the pathophysiology of the syndrome that manifests as ARDS. Based on this new understanding, the potential targets for intervention to ameliorate the systemic inflammatory response have proliferated. Examples include the cytokine network and its receptors, antioxidants, and endothelins. Apart from the challenge of testing these agents in experimental models, it seems likely that determination of the optimum combination of agents will become an equally important endeavor. A particular challenge is to develop better methods of predicting which of the many at-risk patients will go on to full-blown ARDS and MODS, thereby targeting subgroups of patients most likely to benefit from anti-inflammatory therapies. Similarly, the adverse effects of immunosuppressive therapy may be diminished by improved, perhaps molecular, techniques to detect microbial pathogens and permit differentiation between Systemic inflammatory response syndrome and sepsis.

    The current study was conducted to examine the prevalence and correlates of mental distress among survivors of adolescent and young adult (AYA) cancer and a comparison group. A total of 875 AYA cancer survivors who were diagnosed between the ages of 15 and 39 years and who were at least 5 years from their initial diagnosis were identified from the 2013 and 2014 National Health Interview Surveys. A comparison group was created. The Kessler nonspecific mental/psychological distress scale was used to examine none/low, moderate, and severe distress. The issues of whether individuals talked to mental health professionals within the previous year and if they could afford mental health care also were examined. Variables (ie, demographics, behavioral [eg, smoking status], comorbidity, and mental health visits) associated with distress among the 2 groups were identified using multinomial logistic regressions. Survivors reported mental distress more often than the comparison group (moderate: 23.2% vs 16.9%; and severe: 8.4% vs 3.0% [P<.001]). Survivors cited not being able to afford mental health care more often (6.4% vs 2.3%; P = .002). Moreover, 74.7% and 52.2% of survivors, respectively, with moderate and severe distress had not talked to a mental health professional. Contrary to the comparison group, survivors who were current smokers reported severe distress more often compared with nonsmokers (relative risk, 3.59; 95% confidence interval, 1.46-8.84 [P = .01]). Having public and no insurance versus private insurance and report of sleep-related trouble within the previous week were found to be associated with greater distress among survivors. AYA cancer survivors are more likely to demonstrate mental distress than individuals without cancer. Nevertheless, few survivors may be receiving professional mental health services. Survivors need greater access to mental health screening and counseling to address the current gaps in care delivery. Cancer 2017;123:869-78.

    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.

  17. Pulmonary pathology of acute respiratory distress syndrome.

    PubMed

    Lung morphology in ARDS reflects the rapid evolution from interstitial and alveolar edema to end-stage fibrosis consequent to injury of the alveolocapillary unit. This morphologic progression, termed diffuse alveolar damage, has been subdivided into sequentially occurring exudative, proliferative, and fibrotic phases. Pulmonary lesions correlate with the phase of alveolar damage rather than its specific cause. The pathologic features are consistent with the effects of a host of injurious stimuli and the complex interaction of inflammatory mediators on alveolar epithelial and capillary endothelial cells. Although ARDS frequently culminates in "interstitial" fibrosis, the organization of intraluminal exudate dominates the histologic picture in the proliferative phase and establishes the framework for subsequent fibrous remodeling of the lung. Involvement of the pulmonary vasculature is an important aspect of ARDS, from the initial phase of edema to the terminal stage of intractable pulmonary hypertension. Vascular lesions include thrombotic, fibroproliferative, and obliterative changes that, like the parenchymal lesions, correlate with the temporal phase of DAD. Although ARDS is characterized by extensive bilateral lung involvement, alveolar damage can also affect the lung in a localized fashion. RAD is associated with the same clinical risk factors as DAD, suggesting that there is a spectrum in the extent of lung involvement and disease severity in patients at risk for ARDS. The factors that govern which patients will develop the fulminant syndrome are poorly understood. It must be re-emphasized that the lung is stereotyped in its response to injury and, consequently, descriptive, or even quantitative, studies of lung morphology can only provide clues regarding the initiating factors and pathogenetic mechanisms of ARDS. Progress in understanding the pathogenesis of ARDS and development of rational approaches to therapy will ultimately depend on careful clinical and

    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%.

    Whether tuberculosis-related acute respiratory distress syndrome is associated with worse outcomes when compared with acute respiratory distress syndrome secondary to other causes remains unknown. Herein, we compare the outcomes between the two groups. Retrospective analysis of all subjects admitted with acute respiratory distress syndrome over the last 16 years. Respiratory ICU of a tertiary care hospital in North India. Consecutive subjects with acute respiratory distress syndrome. Subjects were categorized as tuberculosis-related acute respiratory distress syndrome and acute respiratory distress syndrome-others and were managed with mechanical ventilation using the low tidal volume strategy as per the Acute Respiratory Distress Syndrom Network protocol. The baseline clinical and demographic characteristics, lung mechanics, and mortality were compared between the two groups. Factors predicting ICU survival were analyzed using multivariate logistic regression analysis. During the study period, 469 patients (18 tuberculosis-related acute respiratory distress syndrome and 451 acute respiratory distress syndrome-others) with acute respiratory distress syndrome were admitted. The mean (SD) age of the study population (52.9% women) was 33.6 years (14.8 yr). The baseline parameters and the lung mechanics were similar between the two groups. There were 132 deaths (28.1%) with no difference between the two groups (tuberculosis-related acute respiratory distress syndrome vs acute respiratory distress syndrome-others; 27.7% vs 28.2%; p = 0.71). There was also no significant difference in the ventilator-free days, ICU, and the hospital length of stay. On multivariate logistic regression analysis, the factors predicting survival were the admission Acute Physiology and Chronic Health Evaluation II score and baseline driving pressure after adjusting for PaO2:FIO2 ratio, gender, and the etiology of acute respiratory distress syndrome.

    After a more successful treatment of pediatric cancer, the number of childhood cancer survivors is progressively increasing. Consequently, awareness of psychological late sequelae is important. The Hospital Anxiety and Depression Scale (HADS) was used as a screening tool for emotional distress in a single center cohort of 652 childhood cancer survivors (median age 23 y [range, 15 to 46 y], median follow-up time 15 y [range, 5 to 42 y]). Results were compared with a control group of 440 Dutch subjects. A higher HADS score linearly reflect a higher level of emotional distress, and a score ≥15 is indicative of clinically significant emotional distress. Mean HADS score of the childhood cancer survivors was not different from the control group (P=0.38). Survivors exposed to global central nervous system (CNS) irradiation had a significantly higher HADS score than the control group (8.3±6.6; P=0.05) as well as other survivors (P=0.01). Forty-three survivors (7%) had a HADS score ≥15. Survivors with a HADS score ≥15 were variously spread over the diagnostic-related and treatment-related subgroups. Linear regression analysis showed that high educational achievement (β=-1.28; P<0.01) and age at the time of the study (β=0.08; P=0.03) were both significantly associated with the HADS score. Emotional distress does not occur more often in childhood cancer survivors than in the normal population. No disease-related or treatment-related variable was independently associated with emotional distress.

    The combined effects of optimized chemotherapy, surgery, radiotherapy, stem cell transplantation regimens, and improved supportive care had drastically increased the survival rate of childhood cancer. Hence, the number of adult survivors of childhood cancer is on the raise and this subset of population is gaining more attention due to the late effects of their cancer therapy. There is growing evidence that pediatric cancer survivors are at a greater risk of developing metabolic syndrome (MS) or the MS component traits than the general population. There is currently no drug therapy to treat MS as a whole disease, as it is a cluster of symptoms that present uniquely among different individuals. Given the recent recognition of MS in adult survivors of childhood cancer, there is a scarcity of long-term follow-up studies of this group. Adherence to a healthy lifestyle with both dietary and physical activity is the only most powerful and most useful armor available now against obesity and its metabolic complications.

    Acute respiratory distress syndrome (ARDS) is defined by acute diffuse inflammatory lung injury invoked by a variety of systemic or pulmonary insults. Despite medical progress in management, mortality remains 27% to 45%. Patients with ARDS should be managed with low tidal volume ventilation. Permissive hypercapnea is well tolerated. Conservative fluid strategy can reduce ventilator and hospital days in patients without shock. Prone positioning and neuromuscular blockers reduce mortality in some patients. Early management of ARDS is relevant to emergency medicine. Identifying ARDS patients who should be transferred to an extracorporeal membrane oxygenation center is an important task for emergency providers.

    In the immuno-competent adult Ebstein-Barr virus (EBV) infection is a self-limiting disease that resolves spontaneously. We report a case of acute respiratory distress syndrome (ARDS) complicating severe EBV pneumonia and requiring prolonged artificial ventilation. The diagnosis was confirmed by specific serology and estimation of the viral load by PCR. Apart from supportive treatment with artificial ventilation the medical treatment included the use of Acyclovir and polyclonal immunoglobulins in the early phase and corticosteroids in the late phase. Recovery was progressive and complete. ARDS can complicate EBV pneumonia in an immuno-competent subject. Its management represents a diagnostic and therapeutic challenge.

    Noncardiogenic pulmonary edema, and, to a lesser extent, acute respiratory distress syndrome (ARDS), are common clinical manifestations of drug-induced lung diseases. Clinical features and radiographic appearances are generally indistinguishable from other causes of pulmonary edema and ARDS. Typical manifestations include dyspnea, chest discomfort, tachypnea, and hypoxemia. Chest radiographs commonly reveal interstitial and alveolar filling infiltrates. Unlike pulmonary edema that is due to congestive heart failure, cardiomegaly and pulmonary vascular redistribution are generally absent in cases that are drug-related. Rare cases of drug-induced myocarditis with heart failure and pulmonary edema have been described. Results from laboratory evaluation and respiratory function tests are nonspecific.

Chest radiography, bedside lung ultrasonography and computed tomography scans can provide useful information for the management of patients and detection of prognostic factors. However, imaging findings are not specific and several possible differential diagnoses should be taken into account. Herein we will review the role of radiological techniques in ARDS, highlight the plain radiological and computed tomography findings according to the pathological stage of the disease (exudative, inflammatory and fibroproliferative), and summarise the main points for the differential diagnosis with cardiogenic oedema, which is still challenging in the acute stage.

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

    Recommendations concerning the management of hemoglobin levels and hematocrit in patients on extracorporeal membrane oxygenation (ECMO) still advise maintenance of a normal hematocrit. In contrast, current transfusion guidelines for critically ill patients support restrictive transfusion practice. We report on a series of patients receiving venovenous ECMO (vvECMO) for acute respiratory distress syndrome (ARDS) treated according to the restrictive transfusion regimen recommended for critically ill patients. We retrospectively analyzed 18 patients receiving vvECMO due to severe ARDS. Hemoglobin concentrations were kept between 7 and 9 g/dL with a transfusion trigger at 7 g/dL or when physiological transfusion triggers were apparent. We assessed baseline data, hospital mortality, time on ECMO, hemoglobin levels, hematocrit, quantities of packed red blood cells received, and lactate concentrations and compared survivors and nonsurvivors. The overall mortality of all patients on vvECMO was 38.9%. Mean hemoglobin concentration over all patients and ECMO days was 8.30 ± 0.51 g/dL, and hematocrit was 0.25 ± 0.01, with no difference between survivors and nonsurvivors. Mean numbers of given PRBCs showed a trend towards higher quantities in the group of nonsurvivors, but the difference was not significant (1.97 ± 1.47 vs. 0.96 ± 0.76 units; P = 0.07). Mean lactate clearance from the first to the third day was 45.4 ± 28.3%, with no significant difference between survivors and nonsurvivors (P = 0.19). In our cohort of patients treated with ECMO due to severe ARDS, the application of a restrictive transfusion protocol did not result in an increased mortality. Safety and feasibility of the application of a restrictive transfusion protocol in patients on ECMO must further be evaluated in randomized controlled trials.

    This study was designed to evaluate prevalence of the metabolic syndrome among cancer survivors compared to non-cancer controls from a population-based sample and to identify associated risk factors. Data from the fourth Korean National Health and Nutrition Examination Survey were analyzed to compare the prevalence of metabolic syndrome, as defined by 2009 consensus criteria. Associated factors with were identified using multiple logistic regression analysis among cancer survivors. The prevalence of the metabolic syndrome in cancer survivors (n = 335) was similar to that in the non-cancer population (n = 10,671). However, gastric cancer survivors showed lower risk of metabolic syndrome than non-cancer controls (adjusted odds ratio [aOR] 0.42, 95% confidence interval [CI] 0.20-0.86). Age of more than 60 years (aOR 4.83, 95% CI 1.94?12.03), BMI between 23 and 25 (aOR 6.71, 95% CI 2.90?15.6), BMI more than 25 (aOR 12.23, 95% CI 5.20?28.77) were significantly associated with the metabolic syndrome in cancer survivors. Cancer survivors are unlikely to have a higher risk of the metabolic syndrome than non-cancer controls in Korea. This finding may be due to a relatively high proportion of gastric cancer survivors in Korea than in Western countries. The risk for metabolic syndrome among cancer survivors would appear to vary according to oncological and non-oncological factors.

  12. Distress signals: Does cognitive behavioural therapy reduce or increase distress in chronic fatigue syndrome/myalgic encephalomyelitis?

    PubMed

    Laws, Keith R

    2017-08-01

    Reducing the psychological distress associated with chronic fatigue syndrome/myalgic encephalomyelitis is seen as a key aim of cognitive behavioural therapy. Although cognitive behavioural therapy is promoted precisely in this manner by the National Institute of Clinical Excellence, the evidence base on distress reduction from randomised controlled trials is limited, equivocal and poor quality. Crucially, data derived from multiple patient surveys point to worsening and increase distress; however, despite being invited, such data have been dismissed as second class by National Institute of Clinical Excellence. Crucially, the claim by National Institute of Clinical Excellence that cognitive behavioural therapy reduces distress in chronic fatigue syndrome/myalgic encephalomyelitis is not only at odds with what patients repeatedly report in surveys, but with their own gold-standard randomised controlled trial and meta-analytic data.

    The pustular and erythrodermic types of psoriasis have been associated with a number of systemic complications, including congestive heart failure and pneumonia. Acute respiratory distress syndrome (ARDS) refers to acute noncardiogenic pulmonary edema with hypoxemia of various causes and has been attributed to pulmonary capillary leak. Recently, 4 cases of generalized pustular or erythrodermic psoriasis have been described associated with a pulmonary capillary leak syndrome. We describe 2 additional patients, 1 with pustular and erythrodermic psoriasis and 1 with erythrodermic psoriasis; who developed ARDS. Radiographic findings, pulmonary capillary wedge pressures, echocardiograms, and, in one case, an open lung biopsy specimen, were consistent with the diagnosis of ARDS. In neither case could we document any of the common causes of acute respiratory failure. Generalized pustular and erythrodermic psoriasis may be complicated by ARDS. The pathogenesis of this complication is unclear, but proinflammatory cytokines may be involved.

    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.

    Reports on metabolic syndrome in nephroblastoma and neuroblastoma survivors are scarce. Aim was to evaluate the occurrence of and the contribution of treatment regimens to the metabolic syndrome. In this prospective study 164 subjects participated (67 adult long-term nephroblastoma survivors (28 females), 36 adult long-term neuroblastoma survivors (21 females) and 61 control subjects (28 females)). Controls were recruited cross-sectionally. Waist and hip circumference as well as blood pressure were measured. Body composition and abdominal fat were assessed by dual energy X-ray absorptiometry (DXA-scan). Laboratory measurements included fasting triglyceride, high density lipoprotein-cholesterol (HDL-C), glucose, insulin, low-density lipoprotein-cholesterol (LDL-C) and free fatty acids (FFA) levels. Median age at follow-up was 30 (range 19-51) years in survivors and 32 (range 18-62) years in controls. Median follow-up time in survivors was 26 (6-49) years. Nephroblastoma (OR = 5.2, P<0.0001) and neuroblastoma (OR 6.5, P<0.001) survivors had more components of the metabolic syndrome than controls. Survivors treated with abdominal irradiation had higher blood pressure, triglycerides, LDL-C, FFA and lower waist circumference. The latter can not be regarded as a reliable factor in these survivors as radiation affects the waist circumference. When total fat percentage was used as a surrogate marker of adiposity the metabolic syndrome was three times more frequent in abdominally irradiated survivors (27.5%) than in non-irradiated survivors (9.1%, P = 0.018). Nephroblastoma and neuroblastoma survivors are at increased risk for developing components of metabolic syndrome, especially after abdominal irradiation. We emphasize that survivors treated with abdominal irradiation need alternative adiposity measurements for assessment of metabolic syndrome.

    Patients with acute respiratory distress syndrome and acute lung injury require mechanical ventilatory support. Acute respiratory distress syndrome and acute lung injury are further complicated by ventilator-induced lung injury. Lung protective ventilation strategies may lead to improved survival. This systematic review is an update of a Cochrane review originally published in 2003 and updated in 2007. To assess the effects of ventilation with lower tidal volume on morbidity and mortality in patients aged 16 years or older affected by acute respiratory distress syndrome and acute lung injury. A secondary objective was to determine whether the comparison between low and conventional tidal volume was different if a plateau airway pressure of greater than 30 to 35 cm H20 was used. In our previous 2007 updated review, we searched databases from inception until 2006. In this third updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and the Web of Science from 2006 to September 2012. We also updated our search of databases of ongoing research and of reference lists from 2006 to September 2012. We included randomized controlled trials comparing ventilation using either a lower tidal volume (Vt) or low airway driving pressure (plateau pressure 30 cm H2O or less), resulting in a tidal volume of 7 ml/kg or less, versus ventilation that used Vt in the range of 10 to 15 ml/kg in adults (16 years old or older) with acute respiratory distress syndrome and acute lung injury. We independently assessed trial quality and extracted data. Wherever appropriate, results were pooled. We applied fixed-effect and random-effects models. We did not find any new study which were eligible for inclusion in this update. The total number of studies remained unchanged, six trials involving 1297 patients. Five trials had a low risk of bias. One trial had an unclear risk of bias. Mortality at day 28 was significantly reduced by lung

    The number of adult survivors of childhood cancer in the general population has increased. As reports on the prevalence of the metabolic syndrome in adult survivors of childhood cancer are scarce, we reviewed the available literature on the components of the metabolic syndrome in adult survivors of childhood cancer. Although there is a lack of studies estimating the prevalence of metabolic syndrome directly, especially prevalence of insulin resistance, obesity, and dyslipidemia is increased in certain groups. Therefore, adult survivors of childhood cancer are at increased risk of developing cerebrovascular and cardiovascular diseases. Accordingly, it is important to identify the predisposing factors of the metabolic syndrome in cohorts of survivors, to introduce medical interventions, and to subsequently decrease the risk of cerebrovascular and cardiovascular events.

Observational study in sixteen children who died with acute respiratory distress syndrome and diffuse alveolar damage. Pediatric intensive care unit. Sixteen children with fatal acute respiratory distress syndrome and diffuse alveolar damage. None. Double immunohistochemistry for cleaved caspase-3 and (pan)cytokeratin in lung tissues obtained at autopsy. Spectral imaging was used for the quantification of immunohistochemistry colocalization of these markers. We found a wide range in the percentage of alveolar epithelial cell surface area with positive cleaved caspase-3 staining in the lungs of children with acute respiratory distress syndrome (from 1% to almost 20%). The degree of caspase-3 immunostaining in epithelial cells positively correlated with age. There is a high variability in the extent of classic apoptosis in lung epithelial cells in pediatric acute respiratory distress syndrome, potentially in part dependent on age.

    This research examines a model of how personality (Five-Factor Model) is related to adjustment to cancer in later life in terms of the presence of continuing cancer-related worry and depression among older adult, long-term cancer survivors. Data from an NCI-funded study with 275 older adult (age 60+), long-term (5+ years) survivors of breast, prostate, and colorectal cancer were examined. Regression analyses identified neuroticism as the strongest predictor of cancer-related worry along with continuing cancer-related symptoms. For depression, three personality dimensions (neuroticism, conscientiousness, and agreeableness) were significant predictors. Findings suggest the importance of considering the central role that survivors' personality characteristics play in understanding cancer-related worries and depression. Understanding these dispositional characteristics is key for social workers and health-care practitioners in counseling survivors experiencing these common mental health effects.

    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.

    Background: Acute respiratory distress syndrome (ARDS) is seen in critically ill patients. Its etiological spectrum in India is expected to be different from that seen in western countries due to the high prevalence of tropical infections. Aim: To study the epidemiological profile of ARDS patients. Setting: A tertiary care hospital in Karnataka, India. Materials and Methods: Retrospective analysis of 150 out of the 169 ARDS patients diagnosed during 2010–2012. Data collected included the clinical features and severity scoring parameters. Results: The mean age of the study population was 42.92 ± 13.91 years. The causes of ARDS included pneumonia (n = 35, 23.3%), scrub typhus (n = 33, 22%), leptospirosis (n = 11, 7.3%), malaria (n = 6, 4%), influenza (H1N1) (n = 10, 6.7%), pulmonary tuberculosis (n = 2, 1.3%), dengue (n = 1, 0.7%), abdominal sepsis (n = 16, 10.7%), skin infection (n = 3, 2%), unknown cause of sepsis (n = 18, 12%), and nonseptic causes (n = 15, 10%). A total of 77 (51.3%) patients survived, 66 (44%) expired, and 7 (4.7%) were discharged against medical advice (AMA). Preexisting comorbidities (46) were present in 13 survivors, 19 nonsurvivors, and four discharged AMA. History of surgery prior to the onset of ARDS was present in one survivor, 13 nonsurvivors, and one discharge AMA. Mean Acute Physiology and Chronic Health Evaluation (APACHE) II, APACHE III, and Sequential Organ Failure Assessment scores in survivors were 9.06 ± 4.3, 49.22 ± 14, and 6.43 ± 2.5 and in nonsurvivors 21.11 ± 7, 86.45 ± 23.5, and 10.6 ± 10, respectively. Conclusion: The most common cause of ARDS in our study was pneumonia, but a large percentage of cases were due to the tropical infections. Preexisting comorbidity, surgery prior to the onset of ARDS, higher severity scores, and organ failure scores were more frequently observed among nonsurvivors than survivors. PMID:28144059

    The open lung approach is a mechanical ventilation strategy involving lung recruitment and a decremental positive end-expiratory pressure trial. We compared the Acute Respiratory Distress Syndrome network protocol using low levels of positive end-expiratory pressure with open lung approach resulting in moderate to high levels of positive end-expiratory pressure for the management of established moderate/severe acute respiratory distress syndrome. A prospective, multicenter, pilot, randomized controlled trial. A network of 20 multidisciplinary ICUs. Patients meeting the American-European Consensus Conference definition for acute respiratory distress syndrome were considered for the study. At 12-36 hours after acute respiratory distress syndrome onset, patients were assessed under standardized ventilator settings (FIO2≥0.5, positive end-expiratory pressure ≥10 cm H2O). If Pao2/FIO2 ratio remained less than or equal to 200 mm Hg, patients were randomized to open lung approach or Acute Respiratory Distress Syndrome network protocol. All patients were ventilated with a tidal volume of 4 to 8 ml/kg predicted body weight. From 1,874 screened patients with acute respiratory distress syndrome, 200 were randomized: 99 to open lung approach and 101 to Acute Respiratory Distress Syndrome network protocol. Main outcome measures were 60-day and ICU mortalities, and ventilator-free days. Mortality at day-60 (29% open lung approach vs. 33% Acute Respiratory Distress Syndrome Network protocol, p = 0.18, log rank test), ICU mortality (25% open lung approach vs. 30% Acute Respiratory Distress Syndrome network protocol, p = 0.53 Fisher's exact test), and ventilator-free days (8 [0-20] open lung approach vs. 7 [0-20] d Acute Respiratory Distress Syndrome network protocol, p = 0.53 Wilcoxon rank test) were not significantly different. Airway driving pressure (plateau pressure - positive end-expiratory pressure) and PaO2/FIO2 improved significantly at 24, 48 and 72 hours in patients

    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. Future research should examine whether incorporating spousal care into psycho-oncology and survivorship programs improves survivor outcomes. PMID:26033755

    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.

    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.

    The morbidity and mortality rates associated with acute respiratory distress syndrome (ARDS) remain high and the development of new therapeutic strategies is urgently required. Some pharmacological treatments, proposed or under evaluation for ARDS, seek to protect the endothelium and consequently mitigate fluid extravasation into the alveolar space. FG-4497 is a new compound which acts as a prolyl hydroxylase domain 2 inhibitor and mimics hypoxia in the activation of hypoxia-inducible factor-2α signaling, decreasing VE-cadherin phosphorylation and thus promoting integrity of adherens junctions. In this special report, we discuss the pharmacological characteristics of FG-4497, its effect on lung parenchyma and other organs and future perspectives in ARDS. In short, FG-4497 may be considered a novel pharmacological option targeting endothelial cell repair in lung diseases such as ARDS. Further experimental and clinical studies are warranted to better understand the mechanisms of action of FG-4497 in different types of lung injury.

    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

    Driving pressure has been proposed as a major determinant of outcome in patients with acute respiratory distress syndrome (ARDS), but there is little data examining the association between pulmonary mechanics, include driving pressure, and outcomes in mechanically ventilated patients without ARDS. Secondary analysis from 1,705 mechanically ventilated patients enrolled in a clinical study that examined outcomes associated with the use of early lung-protective mechanical ventilation. The primary outcome was mortality and the secondary outcome was the incidence of ARDS. Multivariable models were constructed to: 1) define the association between pulmonary mechanics (driving pressure, plateau pressure, and compliance) and mortality; and 2) evaluate if driving pressure contributed information beyond that provided by other pulmonary mechanics. The mortality rate for the entire cohort was 26.0%. Compared with survivors, non-survivors had significantly higher driving pressure [15.9 (5.4) vs. 14.9 (4.4), p = 0.005] and plateau pressure [21.4 (5.7) vs. 20.4 (4.6)), p = 0.001]. Driving pressure was independently associated with mortality [adjusted OR, 1.04 (1.01-1.07)]. Models related to plateau pressure also revealed an independent association with mortality, with similar effect size and interval estimates as driving pressure. There were 152 patients that progressed to ARDS (8.9%). Along with driving pressure and plateau pressure, mechanical power [adjusted OR, 1.03 (1.00-1.06)] was also independently associated with ARDS development CONCLUSIONS:: In mechanically ventilated patients, driving pressure and plateau pressure are risk factors for mortality and ARDS, and provide similar information. Mechanical power is also a risk factor for ARDS.

    A better understanding of health-related quality of life (HRQoL) and psychological distress in cancer survivors can raise awareness, promote the development of policies in cancer survivorship care, and facilitate better targeted use of limited resources in low- and middle-income countries (LMICs). The main objectives of this paper were therefore to assess HRQoL and the prevalence of psychological distress amongst cancer survivors in Southeast Asia and identify risk factors of these outcomes. The ACTION study was a longitudinal study in eight LMICs in Southeast Asia with 5249 first time cancer survivors followed up at 1 year after diagnosis. HRQoL was assessed using the EORTC QLQ-C30 and EQ-5D. Psychological distress (anxiety and depression) was assessed using the Hospital Anxiety and Depression Scale. General linear models and multiple logistic regression were used to identify independent predictors of HRQoL and psychological distress. One year after diagnosis, the mean EORTC QLQ-C30 global health score for survivors was 66.2 out of 100 (SD 22.0), the mean index score on the EQ-5D was 0.74 (SD 0.23), 37% of survivors had at least mild levels of anxiety, and 46% showed at least mild levels of depression. Poorest HRQoL and highest prevalence of anxiety and depression were seen in patients with lung cancer and lymphomas, while highest scores and least psychological distress were seen in female patients with breast and cervical cancer. The most significant predictor of poor HRQoL and psychological distress outcomes was cancer stage at diagnosis. Age, co-morbidities, treatment, and several socioeconomic factors were associated with HRQoL and psychological distress. Cancer survivors in LMICs in Southeast Asia have impaired HRQoL and substantial proportions have psychological distress. Patients with advanced cancer stages at diagnosis and those in a poor socioeconomic position were most at risk of such poor outcomes. Supportive interventions for cancer patients that

    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.

  16. Pulmonary and extrapulmonary acute respiratory distress syndrome: are they different?

    PubMed

    2008-06-01

    The pathogenesis of acute respiratory distress syndrome (ARDS) has been described by the presence of direct (pulmonary) and/or indirect (extrapulmonary) insult to the lung parenchyma. Evidence indicates that the pathophysiology of ARDS may differ according to the type of primary insult. This article presents a brief overview of differences between pulmonary and extrapulmonary ARDS, and discusses the interactions between morpho-functional aspects and response to differents therapies, both in experimental and clinical studies. This systematic review included clinical and experimental ARDS studies found in MedLine and SciElo databases in the last 20 years. Many researchers acknowledge that experimental pulmonary and extrapulmonary ARDS are not identical with regard to morpho-functional aspects, the response to positive end-expiratory pressure (PEEP), recruitment manoeuvre, prone position and other adjunctive therapies. However, contradictory results have been reported in different clinical studies, which could be attributed to the difficulty of classifying ARDS in one or the other category, and to the assurance regarding the onset, phase and severity of ARDS in all patients. Heterogeneous ARDS patients are still considered as belonging to one syndrome, and are therefore treated in a similar manner. Thus, it is important to understand the pathophysiology of pulmonary and extrapulmonary ARDS in an attempt to better treat these patients.

    Acute respiratory distress syndrome (ARDS), the most severe manifestation of acute lung injury (ALI), is described as a stereotyped response to lung injury with a transition from alveolar capillary damage to a fibroproliferative phase. Most ARDS patients survive the acute initial phase of lung injury and progress to either reparation of the lesion or evolution of the syndrome. Despite advances in the management of ARDS, mortality remains high (40%) and autopsies show extended pulmonary fibrosis in 55% of patients, suggesting the importance of deregulated repair in the morbidity and mortality of these patients. Factors influencing progression to fibroproliferative ARDS versus resolution and reconstitution of the normal pulmonary parenchymal architecture are poorly understood. Abnormal repair and remodeling may be profoundly affected by both environmental and genetic factors. In this line, mechanical ventilation may affect the macromolecules that constitute the extracellular matrix (collagen, elastin, fibronectin, laminin, proteoglycan and glycosaminoglycans), suffer changes and impact the biomechanical behavior of lung parenchyma. Furthermore, evidence suggests that acute inflammation and fibrosis may be partially independent and/or interacting processes that are autonomously regulated, and thus amenable to individual and specific therapies. In this review, we explore recent advances in the field of fibroproliferative ARDS/ALI, with special emphasis on 1) the physiological properties of the extracellular matrix, 2) the mechanisms of remodeling, 3) the impact of mechanical ventilation on lung fibrotic response, and (4) therapeutic interventions in the remodeling process.

    The objective of this review is to provide an comprehensive overview of the evolution of acute respiratory distress syndrome (ARDS) in cellular, animal and human models with specific reference to sepsis and haemorrhage. Within this work we have attempted to describe the temporal evolution of the disease process.ARDS is a complication of pulmonary and systemic disease and it can follow sepsis or haemorrhage. The definition of this condition states an acute onset and this review seeks to clarify the time course of that onset following sepsis and haemorrhage. The underlying pathophysiological mechanisms include activation of the immune response, neutrophil activation and sequestration of these into the alveolus with subsequent tissue damage and hypoxia. The biological evolution of these processes from sepsis or haemorrhage has been well described and the earliest measurable changes in the process occur within 15 min with the clinical manifestations of the syndrome occurring within 12 h. The rapid development of this condition should be considered during the treatment of haemorrhagic or septic shock.

    to review the evolution of acute respiratory distress syndrome (ARDS) definitions and present the current definition for the syndrome. a literature review and selection of the most relevant articles on ARDS definitions was performed using the MEDLINE®/PubMed® Resource Guide database (last ten years), in addition to including the most important articles (classic articles) that described the disease evolution. the review included the following subjects: introduction; importance of definition; description of the first diagnostic criterion and subsequently used definitions, such as acute lung injury score; definition by the American-European Consensus Conference, and its limitations; description of the definition by Delphi, and its problems; accuracy of the aforementioned definitions; description of most recent definition (the Berlin definition), and its limitations; and practical importance of the new definition. ARDS is a serious disease that remains an ongoing diagnostic and therapeutic challenge. The evolution of definitions used to describe the disease shows that studies are needed to validate the current definition, especially in pediatrics, where the data are very scarce.

    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 respiratory distress syndrome is a common cause of acute respiratory failure that is underdiagnosed both inside and outside of intensive care units. Progression to the most severe forms of the syndrome confers a mortality rate greater than 40% and is associated with often severe functional disability and psychological sequelae in survivors. While there are no disease-modifying pharmacotherapies for the syndrome, this progression may be prevented through the institution of quality improvement measures that minimise iatrogenic injury associated with acute severe illness. © Royal College of Physicians 2017.

    Few studies have been conducted on psychological disorders other than post-traumatic stress disorder (PTSD) in war survivors. The aim of this study was to examine PTSD, social anxiety disorder (SAD), and major depressive disorder (MDD) and their associations with distress and quality of life in 174 Albanian civilian survivors of the Kosovo war. This included testing of conceptual models suggesting that experiential avoidance might influence associations between anxiety and mood disorders with psychological functioning. Each of the three psychiatric disorders was associated with greater experiential avoidance and psychological distress, and lower quality of life. Being a refugee was associated with a higher likelihood of having SAD and MDD. We found evidence for experiential avoidance as a partial mediator of the respective effects of SAD and PTSD on quality of life; experiential avoidance did not mediate the effects of disorders on global distress. We also found support for a moderation model showing that only war survivors without SAD and low experiential avoidance reported elevated quality of life; people with either SAD or excessive reliance on experiential avoidance reported compromised, low quality of life. This is the third independent study, each using a different methodology, to find empirical support for this moderation model (Kashdan & Breen, 2008; Kashdan & Steger, 2006). Overall, we provided initial evidence for the importance of addressing PTSD, SAD, MDD, and experiential avoidance in primarily civilian war survivors. PMID:18676121

    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

    BACKGROUND: To determine the prevalence of metabolic syndrome in survivors of childhood leukemia in Isfahan, Iran. METHODS: During a 4-year period (2003 to 2007), 55 children (33 male and 22 female) diagnosed with ALL at Unit of Hematology/ Oncology, Department of Pediatrics, Isfahan University of Medical Science, were enrolled in this cross-sectional study. Metabolic syndrome was defined using the modified version of Adult Treatment Panel (ATP III) crite-ria. Insulin resistance was defined based on the homeostasis model assessment index (HOMA-IR). RESULTS: The mean age of participates was 10.4 years (range 6-19 years) and the mean interval since completion of chemotherapy was 35 months. Twenty percent (11/55) of survivors (10 male, 1 female) met criteria for diagnosis of metabolic syndrome. Obesity was observed in one forth of patients and nearly 3/4 of obese patients had metabolic syndrome. High serum insulin levels were found in 16% of participants and in 63% of obese survivors. The mean insulin levels in survivors with metabolic syndrome was three-times more than those without (28.3 mu/l vs. 9.57 mu/l, p = 0.004). Insulin resistance was detected in 72.7% of survivors with metabolic syndrome and it was positively correlated with serum triglycerides (0.543, p ≤ 0.001), systolic and diastolic BP (0.348, p = 0.01 and 0.368, p = 006 respectively), insulin levels (0.914, p < 0.001) and blood sugar (0.398, p = 003). CONCLUSIONS: The prevalence of metabolic syndrome in survivors of childhood leukemia in Iran is higher than developed countries. Nearly all of the obese patients had metabolic syndrome. Weight control and regular physical exercise are recommended to the survivors. PMID:21772869

    The development of the acute respiratory distress syndrome (ARDS) carries significant risk of morbidity and mortality. To date, pharmacologic therapy has been largely ineffective for patients with ARDS. We present our personal review aimed at outlining current and future directions for the pharmacologic prevention of ARDS. Several available risk-stratification or prediction scores strategies for identification of patients at risk of ARDS have been reported. Although not ready for the clinical everyday use, they are and will be instrumental in the ongoing and future trials of pharmacoprevention of ARDS. Several systemic medications established the potential role in ARDS prevention based on the preclinical studies and observational data. Due to potential for systemic adverse effects to neutralize any pharmacologic benefits of systemic therapy, inhaled medications appear particularly attractive candidates for ARDS prevention. This is because of their direct delivery to the site of the proposed action (lungs), while pulmonary epithelial surface is still functional. We postulate that overall morbidity and mortality rates from ARDS in the future will be contingent upon decreasing the overall incidence of ARDS through effective identification of those at risk and early application of proven supportive care and pharmacologic interventions.

    Purpose. We report a case of a 60-year-old male who underwent sequential Onyx embolizations of a cerebral arteriovenous malformation (AVM) which we implicate as the most likely etiology of subsequent acute respiratory distress syndrome (ARDS). Methods. Case report and literature review. Results. Shortly after the second Onyx embolization procedure, the patient declined from respiratory failure secondary to pulmonary edema. Clinical entities typically responsible for pulmonary edema including cardiac failure, renal failure, iatrogenic volume overload, negative-pressure pulmonary edema, and infectious etiologies were evaluated and excluded. The patient required mechanical ventilatory support for several days, delaying operative resection. The patient met clinical and radiographic criteria for ARDS. After excluding other etiologies of ARDS, we postulate that ARDS developed as a result of Onyx administration. The Onyx copolymer is dissolved in dimethyl sulfoxide (DMSO), a solvent excreted through the lungs and has been implicated in transient pulmonary side effects. Additionally, a direct toxic effect of the Onyx copolymer is postulated. Conclusion. Onyx embolization and DMSO toxicity are implicated as the etiology of ARDS given the lack of other inciting factors and the close temporal relationship. A strong physiologic rationale provides further support. Clinicians should consider this uncommon but important complication. PMID:21687580

    2015-01-01

    Non-cardiogenic pulmonary edema is a clinical syndrome manifested by rapidly progressive respiratory distress leading, without therapy, to severe respiratory insufficiency and subsequent multiorgan failure. The pathophysiological causes are: the change in the pressure gradients in the pulmonary capillaries, the impaired membrane permeability of the alveolocapillary in the lungs, and impaired lymphatic drainage. Unlike in cardiogenic pulmonary edema, cardiac disease is not a cause, and there is no increase in wedge pressure (< 18 mm Hg). The aetiological base is diverse and includes more clinical pathological factors. The diagnosis and evaluation are usually very difficult due to the rapidly deteriorating clinical condition of the patients. A decisive, quick and comprehensive approach, using all available invasive and non-invasive methods is necessary. The basic steps of treatment are: the use of different types of ventilatory support in order to achieve adequate oxygenation, dealing with possible hemodynamic instability, and, when needed, other specific procedures. It is always important to keep in mind that this is a very serious condition with a high mortality rate. And there is a need for fast and efficient access to the best specialized clinic.

    Acute respiratory distress syndrome (ARDS) is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. It is characterized by an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibroproliferative phase. Despite an improved understanding of ARDS pathobiology, our ability to predict the development of ARDS and risk-stratify patients with the disease remains limited. Biomarkers may help to identify patients at the highest risk of developing ARDS, assess response to therapy, predict outcome, and optimize enrollment in clinical trials. After a short description of ARDS pathobiology, here, we review the scientific evidence that supports the value of various ARDS biomarkers with regard to their major biological roles in ARDS-associated lung injury and/or repair. Ongoing research aims at identifying and characterizing novel biomarkers, in order to highlight relevant mechanistic explorations of lung injury and repair, and to ultimately develop innovative therapeutic approaches for ARDS patients. This review will focus on the pathophysiologic, diagnostic, and therapeutic implications of biomarkers in ARDS and on their utility to ultimately improve patient care. PMID:26980924

The scientific community worked over the years to generate a unified definition of ARDS, which saw its revisited version in the Berlin definition, in 2014. Epidemiologic information about ARDS is limited in the era of the new Berlin definition, and wide differences are reported among countries all over the world. Despite decades of study in the field of lung injury, ARDS is still so far under-recognized, with 2 out of 5 cases missed by clinicians. Furthermore, although advances of ventilator strategies in the management of ARDS associated with outcome improvements-such as protective mechanical ventilation, lower driving pressure, higher PEEP levels and prone positioning-ARDS appears to be undertreated and mortality remains elevated up to 40%. In this review, we cover the history that led to the current worldwide accepted Berlin definition of ARDS and we summarize the recent data regarding ARDS epidemiology.

    Acute respiratory distress syndrome (ARDS) has been a subject of research in the recent decades since it was defined in the seventies. ARDS is now known to be triggered by pulmonary and non-pulmonary insults which allow chemical agents to be released in the lungs. The resulting damage to the alveolar-capillary membrane causes an impaired ventilation and oxygenation. The aim of the present bibliographic review is to describe all the theories that have been proposed since 1974 to explain how the prone position enhances oxygenation in ARDS patients. Current thought amongst researchers includes how the prone position could improve the functional residual capacity, the ventilation/perfusion ratio, the mechanics of lung, diaphragmatic and thoracic movement, the ability to clear secretions, and the release of the lungs from weight of the mediastinal structures. The literature suggests using the prone position in the early stages of ARDS; however it has not been concluded how long prone position should be maintained in order to achieve the best oxygenation levels. The results of the studies reviewed revealed that 50-80% of the patients experienced significant improvement of oxygenation with the prone position. However, no study has shown that the prone position significantly reduces mortality. It is concluded that further investigations are necessary to understand how the prone position affects the lungs, what group of patients respond to this treatment, what duration and frequency of proning is most beneficial to reduce mortality, and how to effectively nurse patients who are in the prone position.

    Acute respiratory distress syndrome (ARDS) is heterogeneous by definition and patient response varies depending on underlying biology and their severity of illness. Although ARDS subtypes have been identified with different prognoses in past studies, the concept of phenotypes or endotypes does not extend to the clinical definition of ARDS. This has possibly hampered the development of therapeutic interventions that target select biological mechanisms of ARDS. Recently, a major advance may have been achieved as it may now be possible to identify ARDS subtypes that may confer different responses to therapy. The aim of personalised medicine is to identify, select, and test therapies that are most likely to be associated with a favourable outcome in a specific patient. Several promising approaches to ARDS subtypes capable of predicting therapeutic response, and not just prognosis, are highlighted in this perspective paper. An overview is also provided of current and future directions regarding the provision of personalised ARDS medicine. The importance of delivering the right care, at the right time, to the right patient, is emphasised. Copyright © 2017 Société française d'anesthésie et de réanimation (Sfar).

    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

    Noninvasive ventilation (NIV) has a well-‑established role in the treatment of acute-‑on-‑chronic respiratory failure and cardiogenic pulmonary edema. Its role in acute hypoxemic respiratory failure has been increasingly investigated, but its impact on the management and outcome of the subset of patients with acute respiratory distress syndrome (ARDS) is still to be determined. ARDS could be a risk factor for NIV failure, and in these patients, delayed endotracheal intubation can lead to an increased mortality. On the other hand, in a subset of patients with ARDS, endotracheal intubation can be avoided when NIV is applied. This review summarizes the current practice of NIV use in patients with ARDS and underlines the importance of proper patient selection before an NIV trial as well as criteria that should be used to predict failure early enough. A brief overview of high-‑flow nasal cannula is also provided. The use of NIV in ARDS is still debated, and it is important to be aware of the potential limitations and pitfalls of this treatment, which, when properly applied, could reduce the incidence of endotracheal intubation.

  17. A Pathophysiologic Approach to Biomarkers in Acute Respiratory Distress Syndrome.

    Acute respiratory distress syndrome (ARDS) is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. It is characterized by an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibroproliferative phase. Despite an improved understanding of ARDS pathobiology, our ability to predict the development of ARDS and risk-stratify patients with the disease remains limited. Biomarkers may help to identify patients at the highest risk of developing ARDS, assess response to therapy, predict outcome, and optimize enrollment in clinical trials. After a short description of ARDS pathobiology, here, we review the scientific evidence that supports the value of various ARDS biomarkers with regard to their major biological roles in ARDS-associated lung injury and/or repair. Ongoing research aims at identifying and characterizing novel biomarkers, in order to highlight relevant mechanistic explorations of lung injury and repair, and to ultimately develop innovative therapeutic approaches for ARDS patients. This review will focus on the pathophysiologic, diagnostic, and therapeutic implications of biomarkers in ARDS and on their utility to ultimately improve patient care.

    Our aims were to describe the prevalence of pulmonary hypertension in patients with acute respiratory distress syndrome (ARDS), to characterize their hemodynamic cardiopulmonary profiles, and to correlate these parameters with outcome. All consecutive patients over 16 years of age who were in the intensive care unit with a diagnosis of ARDS and an in situ pulmonary artery catheter for hemodynamic monitoring were studied. Pulmonary hypertension was diagnosed when the mean pulmonary artery pressure was >25 mmHg at rest with a pulmonary artery occlusion pressure or left atrial pressure <15 mmHg. During the study period, 30 of 402 critically ill patients (7.46%) who were admitted to the ICU fulfilled the criteria for ARDS. Of the 30 patients with ARDS, 14 met the criteria for pulmonary hypertension, a prevalence of 46.6% (95% CI; 28-66%). The most common cause of ARDS was pneumonia (56.3%). The overall mortality was 36.6% and was similar in patients with and without pulmonary hypertension. Differences in patients' hemodynamic profiles were influenced by the presence of pulmonary hypertension. The levels of positive end-expiratory pressure and peak pressure were higher in patients with pulmonary hypertension, and the PaCO2 was higher in those who died. The level of airway pressure seemed to influence the onset of pulmonary hypertension. Survival was determined by the severity of organ failure at admission to the intensive care unit. PMID:25118626

    [Purpose] The aim of this study was to assess the efficacy of noninvasive ventilation (NIV) in acute respiratory distress syndrome (ARDS). [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. PMID:27630415

    Appropriate management of patients with acute respiratory distress syndrome (ARDS) represents a challenge for physicians working in the critical care environment. Significant advances have been made in understanding the pathophysiology of ARDS. There is also an increasing appreciation of the role of ventilator-induced lung injury (VILI). VILI is most likely related to several different aspects of ventilator management: barotrauma due to high peak airway pressures, lung overdistension or volutrauma due to high transpulmonary pressures, alveolar membrane damage due to insufficient positive end-expiratory pressure levels and oxygen-related cell toxicity. Various lung protective strategies have been suggested to minimize the damage caused by conventional modes of ventilation. These include the use of pressure- and volume-limited ventilation, the use of the prone position in the management of ARDS, and extracorporeal methods of oxygen delivery and carbon dioxide removal. Although the death rate resulting from ARDS has been declining over the past 10 years, there is no evidence that any specific treatment or change in approach to ventilation is the cause of this improved survival.

    OBJECTIVE—To determine the effect of birth order on respiratory distress syndrome (RDS) in the outcome of twins in a large premature population managed in a modern neonatal intensive care unit.
METHODS—An historical cohort study design was used to analyse the neonatal outcomes of 301 premature liveborn twin sibling pairs of between 23 and 31 weeks gestation from the Australia and New Zealand Neonatal Network 1995database.
RESULTS—Among the 56 twin sibling pairs who were discordant for RDS, the second twin was affected in 41 cases (odds ratio (OR) 2.7,95% confidence interval (CI) 1.5 to 5.3). The excess risk of RDS in the second twin increased with gestation and was statistically significant for twins above 29 weeks gestation (OR 4.4, 95% CI 1.6 to 15).
CONCLUSIONS—There is a significant increased risk of RDS associated with being the second born of premature twins, which appears to depend on gestation.

    Acute respiratory distress syndrome (ARDS) complicates nosocomial pneumonias (NPn) in 12% to 33% of patients with associated increases in mortality of up to 80%. A timely diagnosis of ARDS with NPn is, however, problematic. The aim of this investigation was to improve the diagnosis and treatment of the early stages of ARDS with NPn. A total of 82 cancer and multiple trauma patients were enrolled in the investigation. Patients were split into 3 groups according to standard ARDS and NPn diagnostic criteria: group 1 ("ARDS + NPn"), group 2 ("NPn"), group 3 ("no ARDS, no NPn"). ARDS was diagnosed using 3 methods: the Murray score, the American-European Consensus Conference criteria, and the V. A. Negovsky Research Institute of General Reanimatology criteria. Elevation of extravascular lung water index along with other ARDS diagnostic criteria (oxygenation index, central hemodynamic indices) was predictive of early stage of ARDS in patients with NPn. The standard diagnostic criteria for ARDS, including the Murray score, oxygenation index, and radiographic data only predicted the later stages of ARDS in NPn. Early diagnosis of ARDS with concomitant NPn in the current study was associated with improved treatment results with decreased duration of artificial ventilation and intensive care unit stay.

    Cognitive-behavioral therapy for postdisaster distress (CBT-PD) is a transdiagnostic intervention that has been used following major disasters such as the 9/11 terrorist attacks and Hurricane Katrina. In this study, we report findings from a community-based treatment program that offered CBT-PD to individuals who experienced Hurricane Sandy. Eight trained community therapists delivered CBT-PD to 342 adults who had been exposed to Hurricane Sandy. Participants were assessed at referral, pretreatment, intermediate treatment, posttreatment and 5-month follow-up. The overall prepost effect size was 1.41, indicating large improvement pre to posttreatment. Gains were maintained at follow-up. Timing of the intervention did not affect outcome. Participants who received the intervention early (i.e., 10 to 15 months after Sandy) had the same improvement as those who received it later (i.e., 21 to 26 months after Sandy). Similarly, there was no difference in outcome between individuals with severe as compared with moderate distress at pretreatment. Results suggest that CBT-PD is appropriate for a range of individuals with moderate to severe distress and that it has benefit both early on as well as two years postdisaster. Findings add to growing literature that CBT-PD should be considered as one important component of a larger disaster response system. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Acute lymphoblastic leukemia (ALL) survivors were screened for risk factors of cardiovascular disease. Forty-four ALL survivors in first remission were enrolled. Twenty-six also received 12-18 Gy cranial radiotherapy (RT). Patients' body mass indexes (BMIs) at dignosis and during the study were compared. Metabolic syndrome (MS) evaluation was performed in patients, parents, and siblings older than 6 years. Homeostasis Model Assessment (HOMA) index of the survivors was also calculated. In survivors with impaired fasting glucose levels, oral glucose tolerance test (OGTT) was performed. Thyroid functions and IGF-1 and/or IGFBP-3 levels of the survivors who received cranial RT were evaluated. Median age of the survivors was 11.5 years (6-23). At diagnosis, mean BMI percentile was 46.7 (3-95) and mean z-score was -0.09 ± 1.14; during the study, these values rose to 71.1 ± 25.6 (3-100) and 0.8 ± 0.94, respectively (P < .001). One patient (2.2%) and nine survivors (20%) were obese at diagnosis and during the study, respectively (P = .005). Survivors had significantly higher BMI percentile and BMI z-score compared to their siblings (P = .006 and P = .011, respectively). The study group was small and we could not show a correlation of the patients' obesity with RT, thyroid functions, IGF-1, and IGFBP-3 levels. In three survivors (6.8%), there was MS. Maternal and paternal MS was not found as a risk factor for MS of the survivors (P = .1, P = .5, respectively). The HOMA index revealed insulin resistance (IR) in 12 (27.2%) of the survivors, whereas OGTT revealed abnormal glucose regulation and/or IR in four. As a conclusion, ALL survivors have high risk for obesity and MS.

    Testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to healthy controls. However, because of the fetal etiology of testicular cancer, familial unrelated healthy men might not be an optimal control group. The objective of this study was to clarify if testicular cancer survivors have impaired gonadal function and increased risk of metabolic syndrome when compared to their biological brothers. A cross-sectional study of testicular cancer survivors (ClinicalTrials.gov number, NCT02240966) was conducted between 2014 and 2016. Of 158 testicular cancer survivors included, 24 had a biological brother who accepted to participate in the study. Serum levels of reproductive hormones and prevalence of metabolic syndrome according to International Diabetes Federation Criteria and National Cholesterol Education Program (Adult Treatment Panel III) criteria comprised the main outcome measures of the study. Median age was similar in testicular cancer survivors and their biological brothers [44 years (IQR 39-50) vs. 46 (40-53) years respectively (p = 0.1)]. In testicular cancer survivors, follow-up since treatment was 12 years (7-19). Serum levels of luteinizing hormone and follicle-stimulating hormone were elevated (p ≤ 0.001), while total testosterone, free testosterone, inhibin B and anti-Müllerian hormone were lower (p ≤ 0.001) in testicular cancer survivors than in their biological brothers. The prevalence of metabolic syndrome was similar and apart from HDL-cholesterol, which was lower in testicular cancer survivors (p = 0.01); there were no differences in the individual components of the metabolic syndrome between testicular cancer survivors and their brothers. In conclusion, gonadal function was impaired in testicular cancer survivors, while we did not detect any difference in the prevalence of metabolic syndrome between testicular cancer survivors and their biological brothers. © 2017 American

    The purpose of this study was to investigate trajectories of psychological distress among low-income, primarily unmarried and African American women who survived Hurricane Katrina (N = 386). 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. © 2013 American Orthopsychiatric Association.

    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). 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. 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). 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. Copyright © 2014 John Wiley & Sons, Ltd.

    A month after the December 2004 tsunami the effect of a 1 week yoga program was evaluated on self rated fear, anxiety, sadness and disturbed sleep in 47 survivors in the Andaman Islands. Polygraph recordings of the heart rate, breath rate and skin resistance were also made. Among the 47 people, 31 were settlers from the mainland (i.e. India, ML group) and 16 were endogenous people (EP group). There was a significant decrease in self rated fear, anxiety, sadness and disturbed sleep in both groups, and in the heart and breath rate in the ML group, and in the breath rate alone in the EP group, following yoga (P < 0.05, t-test). This suggests that yoga practice may be useful in the management of stress following a natural disaster in people with widely differing social, cultural and spiritual beliefs. PMID:18227918

    Objective. Breast cancer survivors are highly sedentary, overweight, or obese, which puts them at increased risk for comorbid chronic disease. We examined the prevalence of, and changes in, metabolic syndrome following 6 months of an aerobic exercise versus usual care intervention in a sample of sedentary postmenopausal breast cancer survivors. Design and Methods. 65 participants were randomized to an aerobic exercise intervention (EX) (n = 35) mean BMI 30.8 (±5.9) kg/m2 or usual care (UC) (n = 30) mean BMI 29.4 (±7.4) kg/m2. Metabolic syndrome prevalence was determined, as well as change in criteria and overall metabolic syndrome. Results. At baseline, 55.4% of total women met the criteria for metabolic syndrome. There was no statistically significant change in metabolic syndrome when comparing EX and UC. However, adhering to the exercise intervention (at least 120 mins/week of exercise) resulted in a significant (P = .009) decrease in metabolic syndrome z-score from baseline to 6 months (−0.76 ± 0.36) when compared to those who did not adhere (0.80 ± 0.42). Conclusions. Due to a higher prevalence of metabolic syndrome in breast cancer survivors, lifestyle interventions are needed to prevent chronic diseases associated with obesity. Increasing exercise adherence is a necessary target for further research in obese breast cancer survivors. PMID:24319454

    Acute respiratory distress syndrome is a common disorder associated with significant mortality and morbidity. The aim of this article is to critically evaluate the definition of acute respiratory distress syndrome and examine the impact the definition has on clinical practice and research. Articles from a MEDLINE search (1950 to August 2007) using the Medical Subject Heading respiratory distress syndrome, adult, diagnosis, limited to the English language and human subjects, their relevant bibliographies, and personal collections, were reviewed. The definition of acute respiratory distress syndrome is important to researchers, clinicians, and administrators alike. It has evolved significantly over the last 40 years, culminating in the American-European Consensus Conference definition, which was published in 1994. Although the American-European Consensus Conference definition is widely used, it has some important limitations that may impact on the conduct of clinical research, on resource allocation, and ultimately on the bedside management of such patients. These limitations stem partially from the fact that as defined, acute respiratory distress syndrome is a heterogeneous entity and also involve the reliability and validity of the criteria used in the definition. This article critically evaluates the American-European Consensus Conference definition and its limitations. Importantly, it highlights how these limitations may contribute to clinical trials that have failed to detect a potential true treatment effect. Finally, recommendations are made that could be considered in future definition modifications with an emphasis on the significance of accurately identifying the target population in future trials and subsequently in clinical care. How acute respiratory distress syndrome is defined has a significant impact on the results of randomized, controlled trials and epidemiologic studies. Changes to the current American-European Consensus Conference definition are

    Circulating cardiac troponin has been associated with adverse prognosis in the acute respiratory distress syndrome in small and single-center studies; however, comprehensive studies of myocardial injury in acute respiratory distress syndrome using modern high-sensitivity troponin assays, which can detect troponin at much lower circulating concentrations, have not been performed. We performed a prospective cohort study. We included patients enrolled in previously completed trials of acute respiratory distress syndrome. One thousand fifty-seven acute respiratory distress syndrome patients were included. To determine the association of circulating high-sensitivity troponin I (Abbott ARCHITECT), with acute respiratory distress syndrome outcomes, we measured high-sensitivity troponin I within 24 hours of intubation. The primary outcome was 60-day mortality. Detectable high-sensitivity troponin I was present in 94% of patients; 38% of patients had detectable levels below the 99th percentile of a healthy reference population (26 ng/L), whereas 56% of patients had levels above the 99th percentile cut point. After multivariable adjustment, age, cause of acute respiratory distress syndrome, temperature, heart rate, vasopressor use, Sequential Organ Failure Assessment score, creatinine, and PCO2 were associated with higher high-sensitivity troponin I concentration. After adjustment for age, sex, and randomized trial assignment, the hazard ratio for 60-day mortality comparing the fifth to the first quintiles of high-sensitivity troponin I was 1.61 (95% CI, 1.11-2.32; p trend = 0.003). Adjusting for Sequential Organ Failure Assessment score suggested that this association was not independent of disease severity (hazard ratio, 0.95; 95% CI, 0.64-1.39; p = 0.93). Circulating troponin is detectable in over 90% of patients with acute respiratory distress syndrome and is associated with degree of critical illness. The magnitude of myocardial injury correlated with mortality.

    This review examines the 11 randomised clinical trials that have compared different surfactant preparations. Seven trials, enrolling 2488 infants with respiratory distress syndrome (RDS), compared the natural surfactant beractant (Survanta) with the synthetic surfactant colfosceril palmitate (Exosurf Neonatal). Infants treated with beractant had lower oxygen requirements for at least 3 days than those treated with colfosceril palmitate. The infants treated with beractant also had lower risks of neonatal mortality [odds ratio (OR) 0.81; 95% confidence interval (CI) 0.65 to 1.01], retinopathy of prematurity (OR 0.81; 95% CI 0.66 to 0.99), and the combined endpoint of death or bronchopulmonary dysplasia (OR 0.86; 95% CI 0.75 to 0.99), compared with those treated with colfosceril palmitate. Calf lung surfactant extract (CLSE; Infasurf), another natural surfactant, has been compared with colfosceril palmitate in 2 studies: in one as prophylaxis and in the other as rescue therapy. Similar, although nonsignificant, advantages were found for the natural surfactant compared with the synthetic surfactant. In 6 of these 9 trials there was a significant reduction in the odds of pulmonary air leaks (OR 0.53; 95% CI 0.41 to 0.64) for infants treated with natural compared with synthetic surfactants. In 7 trials (3554 infants) comparing natural and synthetic surfactants to treat RDS (6 comparing beractant and colfosceril palmitate, and one CLSE and colfosceril palmitate), there was a significantly reduced risk of neonatal mortality (OR 0.80; 95% CI 0.66 to 0.97) with natural compared with synthetic surfactant treatment. In 2 further trials, different natural surfactant preparations have been compared. Reduced oxygen needs for 24 hours after treatment were found for CLSE and Curosurf (porcine-derived lung surfactant, PLS) when each was compared with beractant. Apparent longer term benefits from these surfactants were not statistically proven. Further trials are needed to be certain

    The management of acute respiratory distress syndrome (ARDS) was investigated with the use of heliox in an experimental model. To investigate whether heliox can be considered a new therapeutic approach in ARDS. ARDS was designed in Wistar albino male rats, 250-300 g in weight, by intratracheal instillation of physiological saline solution. Anesthezied and tracheotomized rats with ARDS were pressure-controlled ventilated. At the end of 210 min, helium gas was tried. All rats were assigned to two groups: Group 1 (n = 10) was the control group, and was given no treatment; group 2 (n = 7) was given heliox (He: O(2) = 50:50). The heliox group received heliox for 1 h continously. Rats were continued to be kept on a ventilator through the experiment. Two hours after the last inhalation, both lungs of the rats were excised for both histopathological examination and immunohistochemical evaluation. Histopathological grading were expressed as median interquartile range. Mann-Whitney U-test was used to assess the relationships between the variables. The infiltation of neutrophils were decreased in rats treated with heliox. Edema in the interstitial and intraalveolar areas was less than that of the control rats. Also, the diminishing of perivascular and/or intraalveolar hemorrhage was apperant. Hyaline membrane (HM) formation decreased in the heliox group compared with the control group. Decreased inducible nitric oxide synthase expression was shown via immunohistochemical examination in the heliox group. The present study histopathologically indicated the effectiveness of heliox in the decreasing of neutrophil infiltation, interstitial/intraalveolar edema, perivascular and/or intraalveolar hemorrhage and HM formation in ARDS. Besides the known effect of heliox in obstructive lung disease, inhaled heliox therapy could be associated with the improvement of inflamation in ARDS.

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

    PubMed Central

    Wilson, Bryan; Typpo, Katri

    2016-01-01

    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

    Measurement of ionized magnesium (IMg) provides an accurate assessment of the free form of Mg, which is the physiologically active form and is most reflective of the biologically active and not easily measurable intracellular Mg fraction. Plasma levels of IMg were measured by ion-selective electrode method in premature newborns with respiratory distress syndrome (RDS), and relationships and correlations between IMg levels and various demographic, prognostic and laboratory characteristics were investigated by comparing the premature newborns with (study group; n = 19) and without RDS (control group; n = 20) in the present study. The values of the postnatal arterial pH and base excess and plasma IMg levels were significantly different between the study and control groups, and the number of newborns with any morbidity was significantly higher in the study group. Within the study group there were significant negative correlations between the plasma IMg levels and the values of the umbilical cord arterial pH (r = -0.621, p = 0.005) and base excess (r = -0.746, p = 0.001), and the value of the postnatal arterial base excess (r = -0.585, p = 0.008). The newborns who died later had higher plasma IMg levels than those who survived (0.89 +/- 0.45 vs. 0.63 +/- 0.24 mmol/l, p = 0.026). These findings suggest that increase of plasma IMg may be due to extracellular movement of Mg, which is a principally intracellular ion, as a result of acidosis, hypoxia and probable cellular injury during the early course of RDS. The exact pathophysiological mechanism responsible for IMg increase, and whether determination of plasma IMg level, including umbilical cord blood IMg measurement, can be used as an early or predictive indicator of RDS in the diagnosis remain to be determined in further large-scale studies.

    Purpose Assess the case rate of Acute Respiratory Distress Syndrome (ARDS) after near-hanging, and the secondary outcomes of traumatic and/or anoxic brain injury, and death. Risk factors for the outcomes were assessed. Method Single-center, state-wide retrospective cohort study of consecutive patients admitted between August, 2002, and September, 2011, with a primary diagnosis of non-judicial "hanging injury". Results Of 56 patients, 73% were male. The median age was 31 (IQR: 16–56). Upon arrival, 9% (5/56) did not have a pulse, and 23% (13/56) patients were intubated. The median Glasgow Coma Scale (GCS) was 13 (IQR: 3–15); 14% (8/56) had a GCS=3. ARDS developed in 9% (5/56) of patients. Traumatic anoxic brain injury resulted in 9% (5/56) of patients. The in-hospital case fatality was 5% (3/56). Lower median GCS [3 (IQR: 3–7) vs. 14 (IQR: 3–15), p=0.0003] and intubation in field or in trauma resuscitation unit [100% (5/5) vs. 16% (8/51), p=0.0003] were associated with ARDS development. Risk factors of death were GCS=3 [100% (3/3) vs. 9% (5/53), p=0.002]; pulselessness upon arrival of emergency medical services [100% (3/3) vs. 4% (2/53), p<0.001]; and abnormal neurologic imaging [50% (1/2) vs. zero, p=0.04]. Conclusions The ARDS case rate after near-hanging is similar to the general trauma population. Low GCS and intubation are associated with increased risk of ARDS development. The rate of traumatic and/or anoxic brain injury in this population is low. PMID:25596627

    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.

    Acute respiratory distress syndrome (ARDS) is a disease associated with a high mortality rate. The initial phase is characterized by induction of inflammatory cytokines and chemokines and influx of circulating inflammatory cells, including macrophages which play a pivotal role in the innate and adaptive immune responses to injury. Growing evidence points to phenotypic heterogeneity and plasticity between various macrophage activation states. In this study, gene expression in alveolar macrophages and circulating leukocytes from healthy control subjects and patients with ARDS was assessed by mRNA microarray analysis. Both alveolar macrophages and circulating leukocytes demonstrated up-regulation of genes encoding chemotactic factors, antimicrobial peptides, chemokine receptors, and matrix metalloproteinases. Two genes, the pro-inflammatory S100A12 and the anti-inflammatory IL-1 decoy receptor IL-1R2 were significantly induced in both cell populations in ARDS patients, which was confirmed by protein quantification. Although S100A12 levels did not correlate with disease severity, there was a significant association between early plasma levels of IL-1R2 and APACHE III scores at presentation. Moreover, higher levels of IL-1R2 in plasma were observed in non-survivors as compared to survivors at later stages of ARDS. These results suggest a hybrid state of alveolar macrophage activation in ARDS, with features of both alternative activation and immune tolerance/deactivation.. Furthermore, we have identified a novel plasma biomarker candidate in ARDS that correlates with the severity of systemic illness and mortality.

    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

    Adult survivors of childhood cancer have been reported to have an increased risk of late sequels. A cluster of abnormalities that contribute to the metabolic syndrome may be expressed at a higher level and therefore result in an increased risk for diabetes mellitus and cardiovascular diseases. We investigated a single-centre cohort of 500 adult survivors (228 females) of childhood cancer, median age 28 years (range 18-59 years) and median follow-up time 19 years (range 6-49 years). We measured total cholesterol, high-density lipoprotein-cholesterol, systolic and diastolic blood pressure, body mass index and the prevalence of diabetes mellitus. Data from the epidemiological Monitoring van Risicofactoren en Gezondheid in Nederland (MORGEN) study were used to calculate standard deviation scores as normative values. The criteria of the metabolic syndrome were met in 13% of the total cohort. Acute lymphoblastic leukaemia (ALL) survivors treated with cranial irradiation had an increased risk of developing the metabolic syndrome compared with ALL survivors not treated with cranial irradiation (23% versus 7%, P = 0.011), probably determined by higher prevalence of overweight and hypertension. Adult survivors of childhood cancer, especially those treated with cranial irradiation, are at increased risk of developing the metabolic syndrome.

    Prone positioning (PP) improves oxygenation and may provide a benefit in patients with acute respiratory distress syndrome (ARDS). This approach adds significant challenges to patients in intensive care by limiting access to the endotracheal or tracheostomy tube and vascular access. PP also significantly complicates burn care by making skin protection and wound care more difficult. We hypothesize that PP improves oxygenation and can be performed safely in burn patients with ARDS. PP was implemented in a burn intensive care unit for 18 patients with severe refractory ARDS. The characteristics of these patients were retrospectively reviewed to evaluate the impact of PP on Pao2:FiO2 ratio (PFR) during the first 48 hours of therapy. Each patient was considered his or her own control before initiation of PP, and trends in PFR were evaluated with one-way analysis of variance. Secondary measures of complications and mortality were also evaluated. Mean PFR before PP was 87 (± 38) with a mean sequential organ failure assessment score of 11 (± 4). PFR improved during 48 hours in 12 of 14 survivors (p < 0.05). Mean PFR was 133 (± 77) immediately after PP, 165 (± 118) at 6 hours, 170 (± 115) at 12 hours, 214 (± 126) at 24 hours, 236 (± 137) at 36 hours, and 210 (± 97) at 48 hours. At each measured time interval except the last, PFR significantly improved. There were no unintended extubations. Facial pressure ulcers developed in four patients (22%). Overall, 14 survived 48 hours (78%), 12 survived 28 days (67%), and six survived to hospital discharge (33%). PP improves oxygenation in burn patients with severe ARDS and was safely implemented in a burn intensive care unit. Mortality in this population remains high, warranting investigation into additional complementary rescue therapies. Therapeutic study, level IV. Copyright © 2012 by Lippincott Williams & Wilkins.

    By September 2014, an outbreak of Ebola Viral Disease (EVD) in West African countries of Guinea, Liberia, Sierra Leone, Senegal and Nigeria, had recorded over 4500 and 2200 probable or confirmed cases and deaths respectively. EVD, an emerging infectious disease, can create fear and panic among patients, contacts and relatives, which could be a risk factor for psychological distress. Psychological distress among this subgroup could have public health implication for control of EVD, because of potential effects on patient management and contact tracing. We determined the Prevalence, pattern and factors associated with psychological distress among survivors and contacts of EVD and their relatives. In a descriptive cross sectional study, we used General Health Questionnaire to assess psychological distress and Oslo Social Support Scale to assess social support among 117 participants who survived EVD, listed as EVD contacts or their relatives at Ebola Emergency Operation Center in Lagos, Nigeria. Factors associated with psychological distress were determined using chi square/odds ratio and adjusted odds ratio. The mean age and standard deviation of participants was 34 +/ - 9.6 years. Of 117 participants, 78 (66.7%) were females, 77 (65.8%) had a tertiary education and 45 (38.5%) were health workers. Most frequently occurring psychological distress were inability to concentrate (37.6%) and loss of sleep over worry (33.3%). Losing a relation to EVD outbreak (OR = 6.0, 95% CI, 1.2-32.9) was significantly associated with feeling unhappy or depressed while being a health worker was protective (OR = 0.4, 95% CI, 0.2-0.9). Adjusted Odds Ratio (AOR) showed losing a relation (AOR = 5.7, 95% CI, 1.2-28.0) was a predictor of "feeling unhappy or depressed", loss of a relation (AOR = 10.1, 95% CI, 1.7-60.7) was a predictor of inability to concentrate. Survivors and contacts of EVD and their relations develop psychological distress. Development of psychological distress could be

    This study was conducted to examine the prevalence of and lifestyle factors associated with the metabolic syndrome in breast cancer survivors and to compare those factors with controls without cancer in a community setting. This study included 584 female breast cancer survivors ≥3 years after the initial diagnosis and 2336 age-matched cancer-free female controls from 39 community health examination centers located in 14 urban areas in Korea. The prevalence of the metabolic syndrome is shown. Factors associated with the metabolic syndrome were analyzed as odds ratios (ORs) in cancer survivors and controls; differences between the two groups in the ORs of associated factors were evaluated by calculating p-heterogeneity values. The prevalence of metabolic syndrome in breast cancer survivors and age-matched controls were 26.8% and 26.9%, respectively. Higher percentage of caloric intake from carbohydrates was associated with increased metabolic syndrome only in the breast cancer survivors (OR for the highest vs. lowest quartile for survivors = 2.48 [95% CI = 1.20-5.14]; OR for controls = 1.11 [95% CI = 0.81-1.51]; P-heterogeneity = 0.046). Sweat-inducing exercise for ≥150 min/week was associated with a lower risk of metabolic syndrome only in controls (controls: OR = 0.72 [95% CI = 0.58-0.89]; survivors: OR = 0.88 [95% CI = 0.57-1.36]). Older age, higher body mass index, and a lower education level (≤12 years) was associated with an increased prevalence of metabolic syndrome in both groups. Our results suggest that, in regions with excess carbohydrate intake, the association of the metabolic syndrome with percentage of caloric intake from carbohydrate might be more prominent than exercise in breast cancer survivors, compared with general population.

    The steep rise in thyroid cancer observed in recent decades has caused an increase in the population of long-term thyroid cancer survivors. Other than recurrences of cancer, the long-term health consequences of surviving thyroid cancer, particularly metabolic syndrome, have not yet been determined. The aim of this study was to estimate the risk of metabolic syndrome in thyroid cancer survivors. Population-based data from the Korean National Health and Nutrition Examination Survey (KNHANES) were used for the analysis. The data of KNHANES IV-VI from 2007-2014 were obtained. After excluding subjects who were under 19 years old, whose fasting interval was less than 8 hours, and whose data for predefined variables including metabolic syndrome components were incomplete, 34,347 subjects were analyzed. The incidence of metabolic syndrome and its components were evaluated in three groups: subjects with no history of thyroid cancer, subjects diagnosed with thyroid cancer within 3 years of the survey date, and subjects diagnosed more than 3 years before the survey date. Thyroid cancer diagnoses were made within 3 years of the survey date for 95 subjects (group 1, short-term survivors) and more than 3 years earlier than the survey date for 60 subjects (group 2, long-term survivors). Metabolic syndrome was frequently observed with clinical significance (odds ratio [OR] 1.986 [95% confidence interval [CI] 1.0-3.70], p = 0.030) in short-term survivors compared with subjects with no thyroid cancer history. Risks for having high blood pressure and high fasting glucose were estimated to be higher in the short-term survivor group (OR 2.115 [CI 1.23-3.64], p = 0.006 and OR 1.792 [CI 1.03-3.11], p = 0.038, respectively). No significant associations were noticed in the long-term survivor group when compared with the group with no thyroid cancer history. Risks for metabolic syndrome, especially high blood pressure and high fasting glucose, were increased in short

    In the acute respiratory distress syndrome (ARDS), inflammation in the lungs and other organs can cause life-threatening organ failure. Inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase (statins) can modulate inflammatory responses. Previous observational studies suggested that statins improved clinical outcomes in patients with sepsis. We hypothesized that rosuvastatin therapy would improve clinical outcomes in critically ill patients with sepsis-associated ARDS. We conducted a multicenter trial in which patients with sepsis-associated ARDS were randomly assigned to receive either enteral rosuvastatin or placebo in a double-blind manner. The primary outcome was mortality before hospital discharge home or until study day 60 if the patient was still in a health care facility. Secondary outcomes included the number of ventilator-free days (days that patients were alive and breathing spontaneously) to day 28 and organ-failure-free days to day 14. The study was stopped because of futility after 745 of an estimated 1000 patients had been enrolled. There was no significant difference between study groups in 60-day in-hospital mortality (28.5% with rosuvastatin and 24.9% with placebo, P=0.21) or in mean (±SD) ventilator-free days (15.1±10.8 with rosuvastatin and 15.1±11.0 with placebo, P=0.96). The groups were well matched with respect to demographic and key physiological variables. Rosuvastatin therapy, as compared with placebo, was associated with fewer days free of renal failure to day 14 (10.1±5.3 vs. 11.0±4.7, P=0.01) and fewer days free of hepatic failure to day 14 (10.8±5.0 vs. 11.8±4.3, P=0.003). Rosuvastatin was not associated with an increased incidence of serum creatine kinase levels that were more than 10 times the upper limit of the normal range. Rosuvastatin therapy did not improve clinical outcomes in patients with sepsis-associated ARDS and may have contributed to hepatic and renal organ dysfunction. (Funded by the National Heart, Lung

    In patients undergoing mechanical ventilation for the acute respiratory distress syndrome (ARDS), neuromuscular blocking agents may improve oxygenation and decrease ventilator-induced lung injury but may also cause muscle weakness. We evaluated clinical outcomes after 2 days of therapy with neuromuscular blocking agents in patients with early, severe ARDS. In this multicenter, double-blind trial, 340 patients presenting to the intensive care unit (ICU) with an onset of severe ARDS within the previous 48 hours were randomly assigned to receive, for 48 hours, either cisatracurium besylate (178 patients) or placebo (162 patients). Severe ARDS was defined as a ratio of the partial pressure of arterial oxygen (PaO2) to the fraction of inspired oxygen (FIO2) of less than 150, with a positive end-expiratory pressure of 5 cm or more of water and a tidal volume of 6 to 8 ml per kilogram of predicted body weight. The primary outcome was the proportion of patients who died either before hospital discharge or within 90 days after study enrollment (i.e., the 90-day in-hospital mortality rate), adjusted for predefined covariates and baseline differences between groups with the use of a Cox model. The hazard ratio for death at 90 days in the cisatracurium group, as compared with the placebo group, was 0.68 (95% confidence interval [CI], 0.48 to 0.98; P=0.04), after adjustment for both the baseline PaO2:FIO2 and plateau pressure and the Simplified Acute Physiology II score. The crude 90-day mortality was 31.6% (95% CI, 25.2 to 38.8) in the cisatracurium group and 40.7% (95% CI, 33.5 to 48.4) in the placebo group (P=0.08). Mortality at 28 days was 23.7% (95% CI, 18.1 to 30.5) with cisatracurium and 33.3% (95% CI, 26.5 to 40.9) with placebo (P=0.05). The rate of ICU-acquired paresis did not differ significantly between the two groups. In patients with severe ARDS, early administration of a neuromuscular blocking agent improved the adjusted 90-day survival and increased the time off

    Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (VT), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress syndrome (ARDS), but the relative importance of each of these components is uncertain. Because respiratory-system compliance (CRS) is strongly related to the volume of aerated remaining functional lung during disease (termed functional lung size), we hypothesized that driving pressure (ΔP=VT/CRS), in which VT is intrinsically normalized to functional lung size (instead of predicted lung size in healthy persons), would be an index more strongly associated with survival than VT or PEEP in patients who are not actively breathing. Using a statistical tool known as multilevel mediation analysis to analyze individual data from 3562 patients with ARDS enrolled in nine previously reported randomized trials, we examined ΔP as an independent variable associated with survival. In the mediation analysis, we estimated the isolated effects of changes in ΔP resulting from randomized ventilator settings while minimizing confounding due to the baseline severity of lung disease. Among ventilation variables, ΔP was most strongly associated with survival. A 1-SD increment in ΔP (approximately 7 cm of water) was associated with increased mortality (relative risk, 1.41; 95% confidence interval [CI], 1.31 to 1.51; P<0.001), even in patients receiving "protective" plateau pressures and VT (relative risk, 1.36; 95% CI, 1.17 to 1.58; P<0.001). Individual changes in VT or PEEP after randomization were not independently associated with survival; they were associated only if they were among the changes that led to reductions in ΔP (mediation effects of ΔP, P=0.004 and P=0.001, respectively). We found that ΔP was the ventilation variable that best stratified risk. Decreases in ΔP owing to changes in ventilator settings were strongly associated with

    Although there are similarities in the pathophysiology of acute respiratory distress syndrome in adults and children, pediatric-specific practice patterns, comorbidities, and differences in outcome necessitate a pediatric-specific definition. We sought to create such a definition. A subgroup of pediatric acute respiratory distress syndrome investigators who drafted a pediatric-specific definition of acute respiratory distress syndrome based on consensus opinion and supported by detailed literature review tested elements of the definition with patient data from previously published investigations. International PICUs. Children enrolled in published investigations of pediatric acute respiratory distress syndrome. None. Several aspects of the proposed pediatric acute respiratory distress syndrome definition align with the Berlin Definition of acute respiratory distress syndrome in adults: timing of acute respiratory distress syndrome after a known risk factor, the potential for acute respiratory distress syndrome to coexist with left ventricular dysfunction, and the importance of identifying a group of patients at risk to develop acute respiratory distress syndrome. There are insufficient data to support any specific age for "adult" acute respiratory distress syndrome compared with "pediatric" acute respiratory distress syndrome. However, children with perinatal-related respiratory failure should be excluded from the definition of pediatric acute respiratory distress syndrome. Larger departures from the Berlin Definition surround 1) simplification of chest imaging criteria to eliminate bilateral infiltrates; 2) use of pulse oximetry-based criteria when PaO2 is unavailable; 3) inclusion of oxygenation index and oxygen saturation index instead of PaO2/FIO2 ratio with a minimum positive end-expiratory pressure level for invasively ventilated patients; 4) and specific inclusion of children with preexisting chronic lung disease or cyanotic congenital heart disease.

    Few studies have been conducted on psychological disorders other than post-traumatic stress disorder (PTSD) in war survivors. The aim of this study was to examine PTSD, social anxiety disorder (SAD), and major depressive disorder (MDD) and their associations with distress and quality of life in 174 Albanian civilian survivors of the Kosovo War. This included testing of conceptual models suggesting that experiential avoidance might influence associations between anxiety and mood disorders with psychological functioning. Each of the three psychiatric disorders was associated with greater experiential avoidance and psychological distress, and lower quality of life. Being a refugee was associated with a higher likelihood of having SAD and MDD. We found evidence for experiential avoidance as a partial mediator of the respective effects of SAD and PTSD on quality of life; experiential avoidance did not mediate the effects of disorders on global distress. We also found support for a moderation model showing that only war survivors without SAD and low experiential avoidance reported elevated quality of life; people with either SAD or excessive reliance on experiential avoidance reported compromised, low quality of life. This is the third independent study, each using a different methodology, to find empirical support for this moderation model [Kashdan, T. B., & Breen, W. E. (2008). Social anxiety and positive emotions: a prospective examination of a self-regulatory model with tendencies to suppress or express emotions as a moderating variable. Behavior Therapy, 39, 1-12; Kashdan, T. B., & Steger, M. F. (2006). Expanding the topography of social anxiety: an experience sampling assessment of positive emotions and events, and emotion suppression. Psychological Science, 17, 120-128]. Overall, we provided initial evidence for the importance of addressing PTSD, SAD, MDD, and experiential avoidance in primarily civilian war survivors.

    Verapamil intoxication is a life-threatening condition that often presents with severe hemodynamic instability and requires vasopressor support. There are also documented case reports of the development of non-cardiogenic pulmonary oedema after verapamil overdose. However, the exact mechanisms responsible for pulmonary oedema remain unclear. Here, we describe a 36-year-old woman who was admitted to the intensive care unit after ingesting high-dose verapamil and subsequently developed acute respiratory distress syndrome soon after hemodynamic stabilization. Possible mechanisms are presented after taking into account findings in the current literature. Acute respiratory distress syndrome should be considered early during the evaluation of patients with verapamil intoxication.

These results add to the growing evidence supporting the clinical and research value of measuring pulmonary dead space in patients with acute respiratory distress syndrome and using this pulmonary physiologic end-point as one indicator of a favorable response to therapy.

    A case of acute lung injury (ALI) progressing to acute respiratory distress syndrome (ARDS) requiring tracheal intubation and mechanical ventilation (ETMV) is presented. The palliative medicine service was asked to address concerns expressed by the patient's spouse reflecting uncertainty regarding outcome expectations. Acknowledging and confronting the uncertainties of a critical illness is an essential component of patient-centered communication. Addressing and managing uncertainty for the case scenario requires consideration of both short- and long-term outcomes including mortality, ventilator independence, and adverse effects on quality of life for survivors. In this paper, ALI/ARDS requiring ETMV in the ICU was used as a focal point for preparing a prognostic assessment incorporating these issues. This assessment was based on a review of recently published literature regarding mortality and ventilator independence of survivors for adult patients receiving ETMV for ALI/ARDS in the ICU. In the studies reviewed, long-term survival reported at 60 days to 1 year was 50-73% with greater than 84% of the survivors in each study breathing independently. Selected articles discussing outcomes other than mortality or recovery of respiratory function, particularly quality of life implications for ALI/ARDS survivors, were also reviewed. A case of of ALI/ARDS requiring ETMV in the ICU is used to illustrate the situation of an incapacitated critically ill patient where the outcome is uncertain. Patient-centered communication should acknowledge and address this uncertainty. Managing uncertainty consists of effectively expressing a carefully formulated prognostic assessment and using sound communication principles to alleviate the distress associated with the uncertain outcome probabilities.

    Emotional distress and psychiatric syndromes are prevalent in the breast cancer population at large. However, to date there is a paucity of literature specifically concerning presurgical breast cancer patients. The authors assessed 236 newly diagnosed patients at the time of their presurgical consultation at the Comprehensive Breast Cancer Program of Dartmouth-Hitchcock Medical Center in Lebanon, NH. Of patients in this study, 41% rated their distress in the clinically significant range on the Distress Thermometer (ie, >5, 0-10 scale). Nearly one-half (47%) of patients met established thresholds for positivity on 1 or more screens for distress or psychiatric disorders. Prevalence rates were 11% for major depression (60% of these patients were moderately severe to severely depressed) and were 10% for posttraumatic stress disorder (PTSD). Emotional symptoms markedly interfered with daily function in both groups. Of depressed patients, 56% were already taking a psychotropic medication, yet they still met screening criteria for major depression. Emotional distress and psychiatric syndromes (major depression and PTSD) were prevalent in this population. Markedly impaired function was evident for both depressed and PTSD patients. Future research should refine current screening procedures and develop interventions to better address emotional distress and psychiatric disorders in newly diagnosed breast cancer patients.

    Acute respiratory distress syndrome (ARDS) is a critical condition that is associated with high mortality and morbidity. Aerosolized prostacyclin has been used to improve oxygenation despite the limited evidence available so far.This review was originally published in 2010 and updated in 2017. To assess the benefits and harms of aerosolized prostacyclin in adults and children with ARDS. In this update, we searched CENTRAL (2017, Issue 4); MEDLINE (OvidSP), Embase (OvidSP), ISI BIOSIS Previews, ISI Web of Science, LILACS, CINAHL (EBSCOhost), and three trials registers. We handsearched the reference lists of the latest reviews, randomized and non-randomized trials, and editorials, and cross-checked them with our search of MEDLINE. We contacted the main authors of included studies to request any missed, unreported or ongoing studies. The search was run from inception to 5 May 2017. We included all randomized controlled trials (RCTs), irrespective of publication status, date of publication, blinding status, outcomes published or language. We contacted trial investigators and study authors to retrieve relevant and missing data. Three authors independently abstracted data and resolved any disagreements by discussion. Our primary outcome measure was all-cause mortality. We planned to perform subgroup and sensitivity analyses to assess the effect of aerosolized prostacyclin in adults and children, and on various clinical and physiological outcomes. We assessed the risk of bias through assessment of methodological trial components and the risk of random error through trial sequential analysis. We included two RCTs with 81 participants.One RCT involved 14 critically ill children with ARDS (very low quality of evidence), and one RCT involved 67 critically ill adults (very low quality evidence).Only one RCT (paediatric trial) provided data on mortality and found no difference between intervention and control. However, this trial was eligible for meta-analysis due to a cross

    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

    Genetic variation that regulates insulin resistance, blood pressure and adiposity in the normal population might determine differential vulnerability for metabolic syndrome after treatment for childhood cancer. To evaluate the contribution of candidate single nucleotide polymorphisms (SNPs) relevant for metabolic syndrome in our single centre cohort of adult long-term childhood cancer survivors. In this retrospective study 532 survivors were analysed. Median age at diagnosis was 5.7 years (range 0.0-17.8 years), median follow-up time was 17.9 years (range 5.0-48.8) and median age at follow-up was 25.6 years (range 18.0-50.8). JAZF1 gene rs864745, THADA gene rs7578597, IRS1 gene rs2943641, TFAP2B gene rs987237, MSRA gene rs7826222, ATP2B1 gene rs2681472 and rs2681492 were genotyped. The association of genotypes with total cholesterol levels, blood pressure, body mass index, waist circumference and frequency of diabetes were assessed. Metabolic syndrome was more frequent in cranially (23.3%, P=0.002) and abdominally (23.4%, P=0.009) irradiated survivors as compared with non-irradiated survivors (10.0%). Association of allelic variants in rs2681472 and rs2681492 with hypertension, rs987237 and rs7826222 with waist circumference and rs864745, rs7578597 and rs2943641 with diabetes were not significant. None of the SNPs was associated with the metabolic syndrome. Adjusting for age, sex, follow-up time, cranial irradiation and abdominal irradiation did not change these results. Treatment factors and not genetic variation determine hypertension, waist circumference, diabetes and metabolic syndrome in adult long-term survivors of childhood cancer.

    2012-11-01

    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.

    Both oxygenation and peak inspiratory pressure are associated with mortality in pediatric acute respiratory distress syndrome. Since oxygenation and respiratory mechanics are linked, it is difficult to identify which variables, pressure or oxygenation, are independently associated with outcome. We aimed to determine whether respiratory mechanics (peak inspiratory pressure, positive end-expiratory pressure, ΔP [PIP minus PEEP], tidal volume, dynamic compliance [Cdyn]) or oxygenation (PaO2/FIO2) was associated with mortality. Prospective, observational, cohort study. University affiliated PICU. Mechanically ventilated children with acute respiratory distress syndrome (Berlin). None. Peak inspiratory pressure, positive end-expiratory pressure, ΔP, tidal volume, Cdyn, and PaO2/FIO2 were collected at acute respiratory distress syndrome onset and at 24 hours in 352 children between 2011 and 2016. At acute respiratory distress syndrome onset, neither mechanical variables nor PaO2/FIO2 were associated with mortality. At 24 hours, peak inspiratory pressure, positive end-expiratory pressure, ΔP were higher, and Cdyn and PaO2/FIO2 lower, in nonsurvivors. In multivariable logistic regression, PaO2/FIO2 at 24 hours and ΔPaO2/FIO2 (change in PaO2/FIO2 over the first 24 hr) were associated with mortality, whereas pressure variables were not. Both oxygenation and pressure variables were associated with duration of ventilation in multivariable competing risk regression. Improvements in oxygenation, but not in respiratory mechanics, were associated with lower mortality in pediatric acute respiratory distress syndrome. Future trials of mechanical ventilation in children should focus on oxygenation (higher PaO2/FIO2) rather than lower peak inspiratory pressure or ΔP, as oxygenation was more consistently associated with outcome.

    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

    Acute respiratory distress syndrome is characterized by diffuse inflammatory lung injury and is classified as mild, moderate, and severe. Clinically, hypoxemia, bilateral opacities in lung images, and decreased pulmonary compliance are observed. Sepsis is one of the most prevalent causes of this condition (30 - 50%). Among the direct causes of acute respiratory distress syndrome, chlorine inhalation is an uncommon cause, generating mucosal and airway irritation in most cases. We present a case of severe acute respiratory distress syndrome after accidental inhalation of chlorine in a swimming pool, with noninvasive ventilation used as a treatment with good response in this case. We classified severe acute respiratory distress syndrome based on an oxygen partial pressure/oxygen inspired fraction ratio <100, although the Berlin classification is limited in considering patients with severe hypoxemia managed exclusively with noninvasive ventilation. The failure rate of noninvasive ventilation in cases of acute respiratory distress syndrome is approximately 52% and is associated with higher mortality. The possible complications of using noninvasive positive-pressure mechanical ventilation in cases of acute respiratory distress syndrome include delays in orotracheal intubation, which is performed in cases of poor clinical condition and with high support pressure levels, and deep inspiratory efforts, generating high tidal volumes and excessive transpulmonary pressures, which contribute to ventilation-related lung injury. Despite these complications, some studies have shown a decrease in the rates of orotracheal intubation in patients with acute respiratory distress syndrome with low severity scores, hemodynamic stability, and the absence of other organ dysfunctions.

    Cancer patients can experience significant distress during their cancer trajectory, which impacts upon clinical outcomes and quality of life. Screening for distress using holistic assessments can help identify and address unmet concerns/needs. The purpose of this study was to evaluate the relationship between concerns and distress, and the impact of distress on clinic outcomes in post-treatment head and neck cancer patients. 170 patients attending routine follow-up clinics were prospectively recruited. All patients completed the Patient Concerns Inventory (PCI) and the Distress thermometer (DT) at preconsultation. The rate of significant distress (i.e. DT cut-off score ≥4) was 36% (62/170). Significantly distressed patients selected more items overall than patients without distress (mean, median (QR) of 5.40, 5 (2-8) vs 2.61, 2 (0-4), p < 0.001). Significant distress was most strongly associated with Physical and Functional well-being (p < 0.001) and Psychological and Emotional well-being domains (p = 0.001). On balance, very little difference was noted between cut-off points of either ≥4 or ≥5 PCI items of concern selected. Both cut-off points demonstrated an acceptable level of sensitivity, specificity and predictive values for significant distress. Consultations were longer with increasing numbers of concerns. Just over one-third of patients are significantly distressed. They were more likely to express a higher number of concerns. A cutoff score ≥4 or ≥5 PCI items selected can identify those at risk of significant distress. Concerns causing significant distress were related to emotional/psychological issues and physical function. Copyright © 2017 European Association for Cranio-Maxillo-Facial Surgery.

    With improving short-term mortality in acute respiratory distress syndrome (ARDS), understanding survivors' posthospitalisation outcomes is increasingly important. However, little is known regarding associations among physical, cognitive and mental health outcomes. Identification of outcome subtypes may advance understanding of post-ARDS morbidities. We analysed baseline variables and 6-month health status for participants in the ARDS Network Long-Term Outcomes Study. After division into derivation and validation datasets, we used weighted network analysis to identify subtypes from predictors and outcomes in the derivation dataset. We then used recursive partitioning to develop a subtype classification rule and assessed adequacy of the classification rule using a kappa statistic with the validation dataset. Among 645 ARDS survivors, 430 were in the derivation and 215 in the validation datasets. Physical and mental health status, but not cognitive status, were closely associated. Four distinct subtypes were apparent (percentages in the derivation cohort): (1) mildly impaired physical and mental health (22% of patients), (2) moderately impaired physical and mental health (39%), (3) severely impaired physical health with moderately impaired mental health (15%) and (4) severely impaired physical and mental health (24%). The classification rule had high agreement (kappa=0.89 in validation dataset). Female Latino smokers had the poorest status, while male, non-Latino non-smokers had the best status. We identified four post-ARDS outcome subtypes that were predicted by sex, ethnicity, pre-ARDS smoking status and other baseline factors. These subtypes may help develop tailored rehabilitation strategies, including investigation of combined physical and mental health interventions, and distinct interventions to improve cognitive outcomes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  12. Early-phase changes of extravascular lung water index as a prognostic indicator in acute respiratory distress syndrome patients

    PubMed Central

    2014-01-01

    Background The features of early-phase acute respiratory distress syndrome (ARDS) are leakage of fluid into the extravascular space and impairment of its reabsorption, resulting in extravascular lung water (EVLW) accumulation. The current study aimed to identify how the initial EVLW values and their change were associated with mortality. Methods This was a post hoc analysis of the PiCCO Pulmonary Edema Study, a multicenter prospective cohort study that included 23 institutions. Single-indicator transpulmonary thermodilution-derived EVLW index (EVLWi) and conventional prognostic factors were prospectively collected over 48 h after enrollment. Associations between 28-day mortality and each variable including initial (on day 0), mean, maximum, and Δ (subtracting day 2 from day 0) EVLWi were evaluated. Results We evaluated 192 ARDS patients (median age, 69 years (quartile, 24 years); Sequential Organ Failure Assessment (SOFA) score on admission, 10 (5); all-cause 28-day mortality, 31%). Although no significant differences were found in initial, mean, or maximum EVLWi, Δ-EVLWi was significantly higher (i.e., more reduction in EVLWi) in survivors than in non-survivors (3.0 vs. −0.3 mL/kg, p = 0.006). Age, maximum, and Δ-SOFA scores and Δ-EVLW were the independent predictors for survival according to the Cox proportional hazard model. Patients with Δ-EVLWi > 2.8 had a significantly higher incidence of survival than those with Δ-EVLWi ≤ 2.8 (log-rank test, χ2 = 7.08, p = 0.008). Conclusions Decrease in EVLWi during the first 48 h of ARDS may be associated with 28-day survival. Serial EVLWi measurements may be useful for understanding the pathophysiologic conditions in ARDS patients. A large multination confirmative trial is required. PMID:25593743

  13. Metabolic syndrome and cardiovascular risk in survivors after hematopoietic cell transplantation.

    Baker, K S; Chow, E; Steinberger, J

    2012-05-01

    Increasing numbers of hematopoietic cell transplantations (HCTs) are being performed annually with a greater number of long-term survivors. There is increasing concern regarding the late complications and long-term effects that are secondary to treatment exposures before HCT as well as during the HCT conditioning therapy. In both the autologous as well as allogeneic transplant setting, transplant survivors experience mortality rates higher than the general population and the risk of premature cardiovascular (CV)-related death is increased 2.3-fold compared with the general population. The etiology of CV-related deaths in HCT survivors is multifactorial; however, increasing evidence suggests that HCT survivors are at higher risk of developing adverse CV risk factors leading to the development of the metabolic syndrome (a constellation high triglyceride levels, low high-density lipoprotein-cholesterol, hypertension, high fasting blood sugars and increased waist circumference), which then predisposes individuals to risk for early CV-related death. Resistance to insulin is the primary underlying pathophysiologic mechanism that contributes to the development of metabolic syndrome and HCT survivors have been shown to be more likely to develop hypertension, hyperlipidemia and to be insulin resistant. However, the relationship between HCT-related treatment exposures (total body irradiation, high dose chemotherapy, calcineurin inhibitors, steroids, etc) and transplant-related complications (such as GVHD) with the development of CV risk factors and insulin resistance is still in the early stages of investigation. Greater knowledge of the concern regarding CV risk in HCT survivors among both patients and care providers will provide the opportunity for appropriate screening as well as interventions for modifiable risk factors.

Subjects were 48,934 adults (24,786 men, 24,148 women) aged ≥40yr who receive a routine health examination at 1 hospital from January 2010 to December 2012. There were 2468 cancer survivors, 18,211 with cancer patients in the family, and 28,255 noncancer subjects, who never experienced cancer and whose family members either. Associations between MetS and cancer experience were assessed using multiple logistic regression analysis. The odds ratio (OR) of MetS in female cancer survivors was significantly higher than noncancer subjects after adjusting for age, smoking, physical activity, and alcohol intake (OR = 1.22, 95% confidence intervals: 1.02-1.47]. However, the OR of MetS for male survivors did not differ from that of noncancer subjects. Gastric cancer survivors had a lower OR of MetS than noncancer subjects (0.37, 0.27-0.50). ORs of breast cancer (1.49, 1.00-2.23) and prostate cancer survivors (1.46, 1.07-1.99) were higher than the OR of MetS for noncancer subjects. There was no difference in the OR of MetS between the family members of cancer patients and non-cancer subjects. These findings suggest that the odds of MetS for cancer survivors may differ by cancer type and by sex.

    According to developed countries' studies, in breast cancer survivors there is a high prevalence of metabolic syndrome; however, in Mexico data is lacking about this issue. To explore if metabolic syndrome occurs in Mexican women survivors of breast cancer. At a second-level general hospital, women with breast cancer with a surviving > 2 years were studied. The analysis involved their demographic and anthropometric features, blood pressure measurement, time of surviving, besides fasting blood levels of lipids and glucose. The sample consisted of 100 women; 42% were obese (body mass index > or = 30 kg/m2). The sample's mean age was 60 years with a mean surviving time of 6.5 years. Their mean glucose level was 122 mg/dL and triglycerides 202 mg/dL. There were 33% with blood pressure > or = 130/85mm Hg or diagnosis of hypertension. Fifty-seven percent had glucose > 99 mg/dL or diagnosis of diabetes mellitus, and 58% had triglycerides > 149 mg/dL. Metabolic syndrome occurred in 57% of obese women. Our results suggest that metabolic syndrome occurs in more than 50% of obese Mexican women survivors of breast cancer.

    Experiencing an acute coronary syndrome (ACS) may provoke a range of negative emotional responses, including acute distress and fear of dying. The frequency of these emotional states has rarely been assessed. This study examined the presence and severity of the fear of dying and acute distress in 184 patients with ACS and analyzed its correlates and consequences. Intense distress and fear of dying was reported by 40 patients (21.7%) and moderate fear and distress by 95 patients (51.6%). Intense distress and fear was associated with female gender (odds ratio [OR] 2.49, 95% confidence interval [CI] 1.07 to 2.49), lower levels of education (OR 2.44, 95% CI 1.02 to 5.87), greater chest pain (OR 5.33, 95% CI 1.40 to 20.4), and emotional upset in the 2 hours before onset of ACS (OR 2.70, 95% CI 1.13 to 6.45). Having no acute distress or fear was more common in patients who exercised regularly (OR 3.32, 95% CI 1.35 to 8.18) and who did not initially attribute the chest pain to cardiac causes (OR 2.67, 95% CI 1.10 to 6.47). No association was found with cardiovascular disease history, objective measures of clinical severity, or with clinical presentation of ACS. Acute distress and fear of dying predicted greater depression and anxiety 1 week after ACS (p=0.006), and elevated levels of depression at 3 months (p=0.009), after adjustment for age, gender, and negative affect. In conclusion, distress and fear during the initial stages of an ACS may trigger subsequent depression and anxiety, thereby promoting poorer prognosis and greater morbidity with time.

    Acute respiratory distress syndrome is a life-threatening disorder caused mainly by pneumonia. Clostridium difficile infection (CDI) is a common nosocomial diarrheal disease. Disruption of normal intestinal flora by antibiotics is the main risk factor for CDI. The use of broad-spectrum antibiotics for serious medical conditions can make it difficult to treat CDI complicated by acute respiratory distress syndrome. Fecal microbiota transplantation is a highly effective treatment in patients with refractory CDI. Here we report on a patient with refractory CDI and acute respiratory distress syndrome caused by pneumonia who was treated with fecal microbiota transplantation.

    The biologic effects of variable ventilation may depend on the etiology of acute respiratory distress syndrome. We compared variable and conventional ventilation in experimental pulmonary and extrapulmonary acute respiratory distress syndrome. Prospective, randomized, controlled experimental study. University research laboratory. Twenty-four Wistar rats. Acute respiratory distress syndrome was induced by Escherichia coli lipopolysaccharide administered intratracheally (pulmonary acute respiratory distress syndrome, n = 12) or intraperitoneally (extrapulmonary acute respiratory distress syndrome, n = 12). After 24 hours, animals were randomly assigned to receive conventional (volume-controlled ventilation, n = 6) or variable ventilation (n = 6). Nonventilated animals (n = 4 per etiology) were used for comparison of diffuse alveolar damage, E-cadherin, and molecular biology variables. Variable ventilation was applied on a breath-to-breath basis as a sequence of randomly generated tidal volume values (n = 600; mean tidal volume = 6 mL/kg), with a 30% coefficient of variation (normal distribution). After randomization, animals were ventilated for 1 hour and lungs were removed for histology and molecular biology analysis. Variable ventilation improved oxygenation and reduced lung elastance compared with volume-controlled ventilation in both acute respiratory distress syndrome etiologies. In pulmonary acute respiratory distress syndrome, but not in extrapulmonary acute respiratory distress syndrome, variable ventilation 1) decreased total diffuse alveolar damage (median [interquartile range]: volume-controlled ventilation, 12 [11-17] vs variable ventilation, 9 [8-10]; p < 0.01), interleukin-6 expression (volume-controlled ventilation, 21.5 [18.3-23.3] vs variable ventilation, 5.6 [4.6-12.1]; p < 0.001), and angiopoietin-2/angiopoietin-1 ratio (volume-controlled ventilation, 2.0 [1.3-2.1] vs variable ventilation, 0.7 [0.6-1.4]; p < 0.05) and increased relative

    Comprehensive clinical data provide strong evidence of the efficacy of the synthetic lung surfactant colfosceril palmitate (Exosurf Neonatal) administered as prophylaxis or rescue therapy in infants with respiratory distress syndrome (RDS). The use of rescue therapy with colfosceril palmitate is further supported by cost-effectiveness analyses which report a 9 to 48% reduction in the cost per survivor compared with placebo or historical controls, despite divergent study methodology and location. Importantly, the savings were evident in both larger (> or = 1250g) and smaller (700 to 1350g) infants. All studies considered costs or charges accrued during initial hospitalisation through to 1 year; measurement of long term resource use data and all resulting costs are required for a more complete pharmacoeconomic evaluation. The optimal timing of surfactant administration is likely to be an important economic issue given that efficacy data from a large international trial support earlier administration of colfosceril palmitate versus delayed therapy in high risk patients. Further economic benefits may be realised by the sequential use of antenatal corticosteroids and surfactant therapy, although this has yet to be prospectively investigated. In conclusion, clinical and pharmacoeconomic data strongly support the use of rescue therapy with colfosceril palmitate. Additionally, recent clinical data indicating that even better results may be achieved with earlier administration and/or combined use with antenatal corticosteroids should be assessed from an economic standpoint to determine the optimal prescribing strategy for this agent.

    To describe the effects of high-frequency oscillatory ventilation (HFOV) as a rescue ventilatory support in pediatric patients with acute respiratory distress syndrome (ARDS). Twenty-five children (1 month < age < 17 years) admitted to a university hospital pediatric intensive care unit (ICU) with ARDS and submitted to HFOV for a minimum of 48 hours after failure of conventional mechanical ventilation were assessed. Twenty eight days after the onset of ARDS, the mortality rate was 52% (13/25). Over the course of 48 hours, the use of HFOV reduced the oxygenation index [38 (31-50) vs. 17 (10-27)] and increased the ratio of partial arterial pressure O2 and fraction of inspired O2 [65 [44-80) vs. 152 (106-213)]. Arterial CO2 partial pressure [54 (45-74) vs. 48 (39-58) mmHg] remained unchanged. The mean airway pressure ranged between 23 and 29 cmH2O. HFOV did not compromise hemodynamics, and a reduction in heart rate was observed (141±32 vs. 119±22 beats/min), whereas mean arterial pressure (66±20 vs. 71±17 mmHg) and inotropic score [44 (17-130) vs. 20 (16-75)] remained stable during this period. No survivors were dependent on oxygen. HFOV improves oxygenation in pediatric patients with ARDS and severe hypoxemia refractory to conventional ventilatory support.

    Background During radiotherapy unwanted radiation to normal tissue surrounding the tumor triggers survivorship diseases; we lack a nosology for radiation-induced survivorship diseases that decrease bowel health and we do not know which symptoms are related to which diseases. Methods Gynecological-cancer survivors were followed-up two to 15 years after having undergone radiotherapy; they reported in a postal questionnaire the frequency of 28 different symptoms related to bowel health. Population-based controls gave the same information. With a modified factor analysis, we determined the optimal number of factors, factor loadings for each symptom, factor-specific factor-loading cutoffs and factor scores. Results Altogether data from 623 survivors and 344 population-based controls were analyzed. Six factors best explain the correlation structure of the symptoms; for five of these a statistically significant difference (P< 0.001, Mann-Whitney U test) was found between survivors and controls concerning factor score quantiles. Taken together these five factors explain 42 percent of the variance of the symptoms. We interpreted these five factors as radiation-induced syndromes that may reflect distinct survivorship diseases. We obtained the following frequencies, defined as survivors having a factor loading above the 95 percent percentile of the controls, urgency syndrome (190 of 623, 30 percent), leakage syndrome (164 of 623, 26 percent), excessive gas discharge (93 of 623, 15 percent), excessive mucus discharge (102 of 623, 16 percent) and blood discharge (63 of 623, 10 percent). Conclusion Late effects of radiotherapy include five syndromes affecting bowel health; studying them and identifying the underlying survivorship diseases, instead of the approximately 30 long-term symptoms they produce, will simplify the search for prevention, alleviation and elimination.

    The survival of children with cancer has grown considerably in recent years resulting in a marked increase of endocrine complications. increasingly recognized problems are metabolic syndrome and diabetes mellitus. We critically analysed the most recent literature about the prevalence and molecular mechanisms of metabolic dysregulation and long-term cardio-metabolic risk in this population. Hypothalamic irradiation determines growth hormone deficiency and hypogonadism; moreover it is able to disrupt the appetite regulating centre leading to hyperphagia and progressive obesity. These conditions determine an insulin resistant state, contributing to the development of metabolic syndrome and diabetes mellitus. Irradiation and/or chemotherapy may lead to an insulin secretory defect through a direct damage of pancreatic beta cells. Metabolic syndrome and diabetes mellitus represent increasingly recognized long-term complications of childhood cancer treatment. The different impact of insulin resistance and secretory defects on the onset and progression of metabolic syndrome and diabetes mellitus remains unclear.

In developing countries, mycobacterium tuberculosis is an important cause of community-acquired pneumonia (CAP). TB can present as an acute process and should be included in the differential diagnosis of CAP. This case is special in its manifestation from several clinical perspectives, including the lack of an underlying medical condition or immune defect and the development of acute respiratory distress syndrome (ARDS) in non-miliary and non-disseminated tuberculosis. In conclusion, the diagnosis of TB should be considered in all patients who present with CAP in endemic regions. PMID:27957312

    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. Copyright © 2013 Elsevier España, S.L.U. and SEMICYUC.

    We measured serum levels of pre-B cell colony-enhancing factor (PBEF), which has been suggested as a novel biomarker of sepsis and acute respiratory distress syndrome (ARDS), and evaluated its use as a prognostic biomarker. PBEF was measured in 104 adult ventilated patients who were diagnosed with sepsis upon admission using an enzyme-linked immunosorbent assay. The mean age of our patients was 62.9 ± 12.1 y, and 62 (59.6%) patients were male. The median PBEF level was 5.4 ng/ml (range 1.1-150.7 ng/ml). Non-survivors (n = 57) demonstrated significantly higher PBEF levels than survivors (18.7 ± 34.5 vs 6.9 ± 6.1 ng/ml; p = 0.022). Most particularly, patients with PBEF levels ≥ 10.4 ng/ml (n = 27) demonstrated higher hospital mortality than patients with PBEF levels < 10.4 ng/ml (n = 77) (74.1% vs. 48.1%; p = 0.025). Univariate logistic analysis determined PBEF ≥ 10.4 ng/ml to be an independent factor associated with hospital survival (hazard ratio = 0.324, 95% confidence interval = 0.123-0.854; p = 0.023). Among patients with sepsis-induced ARDS (n = 59), non-survivors (n = 35) demonstrated significantly higher PBEF levels than survivors (n = 24), but not interleukin-6 (IL-6) levels. Our findings indicate that high PBEF is associated with poor clinical outcomes in ventilated patients with sepsis and sepsis-induced ARDS. Serum PBEF might be a better predictor of mortality than IL-6 in patients with sepsis-induced ARDS.

    Introduction Bilirubin is well-recognized marker of hepatic dysfunction in intensive care unit (ICU) patients. Multiple organ failure often complicates acute respiratory distress syndrome (ARDS) evolution and is associated with high mortality. The effect of early hepatic dysfunction on ARDS mortality has been poorly investigated. We evaluated the incidence and the prognostic significance of increased serum bilirubin levels in the initial phase of ARDS. Methods The data of 805 patients with ARDS were retrospectively analysed. This population was extracted from two recent multicenter, prospective and randomised trials. Patients presenting with ARDS with a ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen < 150 mmHg measured with a PEEP ≥ 5 cm of water were included. The total serum bilirubin was measured at inclusion and at days 2, 4, 7 and 14. The primary objective was to analyse the bilirubin at inclusion according to the 90-day mortality rate. Results The 90-day mortality rate was 33.8% (n = 272). The non-survivors were older, had higher Sepsis-related Organ Failure Assessment (SOFA) score and were more likely to have a medical diagnosis on admission than the survivors. At inclusion, the SOFA score without the liver score (10.3±2.9 vs. 9.0±3.0, p<0.0001) and the serum bilirubin levels (36.1±57.0 vs. 20.5±31.5 μmol/L, p<0.0001) were significantly higher in the non-survivors than in the survivors. Age, the hepatic SOFA score, the coagulation SOFA score, the arterial pH level, and the plateau pressure were independently associated with 90-day mortality in patients with ARDS. Conclusion Bilirubin used as a surrogate marker of hepatic dysfunction and measured early in the course of ARDS was associated with the 90-day mortality rate. PMID:26636318

    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

    This study investigated psychological morbidity, quality of life (QoL), colorectal cancer (CRC)-specific symptoms and supportive care needs in a CRC population at the end of treatment (EOT). CRC survivors (n = 152) completed a post-treatment baseline questionnaire as part of a multisite supportive care randomised controlled trial (SurvivorCare). CRC survivors had completed treatment with curative intent within 0 to 6 months. Measures are as follows: Brief Symptom Inventory 18 (BSI-18) (psychological morbidity), EORTC QLQ-C30 and QLQ-CR29 (QoL and CRC-specific symptoms and problems) and Cancer Survivors' Unmet Needs (CaSUN) measure with a simplified response format (unmet needs). Linear regression models were used to compare participants' QoL with a general population sample. Correlation analysis examined associations between psychological morbidity, QoL and CRC-specific symptoms and problems. Average participant age was 64 years, and 51% were male. The majority (68%) had stage 3 disease. In comparison to population norms, CRC survivors had lower depression and anxiety scores (47.4 and 45.6, respectively) but higher somatisation, and lower role, cognitive and social functioning (p < 0.001). CRC survivors had higher fatigue, nausea/vomiting, appetite loss, diarrhoea and financial problems (all p < 0.001), as well as pain (p = 0.002) and constipation (p = 0.019). CRC-specific psychological scores were positively correlated with all three BSI domain scores, and pain and fatigue symptom scores on the QLQ-C30 while negatively correlated with all five functional scales of the QLQ-C30. CRC survivors reported good mental health at EOT. Role and social functioning were impaired compared to population norms, possibly related to physical symptoms. Findings may help guide consultations with patients and inform the design of more tailored supportive care interventions. ACTRN12610000207011.

    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. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Placing the patient in prone position immediately and persistently improved oxygenation: the ratio of P(aO(2)) to fraction of inspired oxygen rose from 47 to 180 mm Hg and the oxygenation index decreased from 40 to 11. The patient survived, with no respiratory sequelae.

    2011-01-01

    Background We aimed to evaluate the effects of chest and motor physiotherapy treatment on hemodynamic variables in preterm newborns with respiratory distress syndrome. Methods We evaluated heart rate (HR), respiratory rate (RR), systolic (SAP), mean (MAP) and diastolic arterial pressure (DAP), temperature and oxygen saturation (SO2%) in 44 newborns with respiratory distress syndrome. We compared all variables between before physiotherapy treatment vs. after the last physiotherapy treatment. Newborns were treated during 11 days. Variables were measured 2 minutes before and 5 minutes after each physiotherapy treatment. We applied paired Student t test to compare variables between the two periods. Results HR (148.5 ± 8.5 bpm vs. 137.1 ± 6.8 bpm - p < 0.001), SAP (72.3 ± 11.3 mmHg vs. 63.6 ± 6.7 mmHg - p = 0.001) and MAP (57.5 ± 12 mmHg vs. 47.7 ± 5.8 mmHg - p = 0.001) were significantly reduced after 11 days of physiotherapy treatment compared to before the first session. There were no significant changes regarding RR, temperature, DAP and SO2%. Conclusions Chest and motor physiotherapy improved cardiovascular parameters in respiratory distress syndrome newborns.

    The GG genotype of the interleukin (IL)-10 promoter polymorphism in position -1082 (-1082GG) has been associated with increased IL-10 production. The current authors hypothesised that the -1082GG genotype is associated with the development of, and outcomes in, acute respiratory distress syndrome (ARDS). A nested case-control study was conducted in 211 Caucasian cases of ARDS and 429 controls who were admitted to an intensive care unit with sepsis, trauma, aspiration or massive transfusions. Cases were followed for organ failure and 60-day mortality. The -1082GG genotype was associated with the development of ARDS, but only in the presence of a significant interaction between the -1082GG genotype and age. Among patients with ARDS, the -1082GG genotype was associated with decreased severity of illness on admission, lower daily organ dysfunction scores and lower 60-day mortality. In conclusion, the high interleukin-10-producing -1082GG genotype may be associated with variable odds for acute respiratory distress syndrome development depending on age. Among those with acute respiratory distress syndrome, the -1082GG genotype is associated with lower mortality and organ failure. Further studies are needed to confirm these findings. PMID:16585075

  1. A new view of pulmonary edema and acute respiratory distress syndrome.

    The old division of lung edema into two categories--cardiogenic (hydrostatic) and noncardiogenic (increased permeability)--is no longer adequate. For instance, it fails to distinguish between the capillary leak caused by acute respiratory distress syndrome from that caused by interleukin-2 treatment. Further, it fails to account for the capillary leak ('stress-failure') that may accompany edema. A modern view of edema must recognize the natural barriers to the formation and spread of edema. These barriers are the capillary endothelium and the alveolar epithelium. Varying degrees of damage to them can account for the varying radiographic and clinical manifestations of lung edema. Thus, interleukin-2 administration causes increased endothelial permeability without causing alveolar epithelial damage. The result is lung edema that is largely confined to the interstitium, causing little hypoxia and clearing rapidly. However, acute respiratory distress syndrome, which is characterized by extensive alveolar damage, causes air-space consolidation, severe hypoxia, and slow resolution. Thus, a reasonable classification of lung edema requires at least four categories: 1) hydrostatic edema; 2) acute respiratory distress syndrome (permeability edema caused by diffuse alveolar damage); 3) permeability edema without alveolar damage; and (4) mixed hydrostatic and permeability edema. The authors emphasize the importance of the barriers provided by the capillary endothelium and the alveolar epithelium in determining the clinical and radiographic manifestations of edema. In general, when the alveolar epithelium is intact, the radiographic manifestations are those of interstitial (not air-space) edema; this radiographic pattern predicts a mild clinical course and prompt resolution.

    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.

    Treatment for rectal and anal cancer (RACa) can result in persistent bowel and gastrointestinal (GI) dysfunction. Body image problems may develop over time and exacerbate symptom-related distress. RACa survivors are an understudied group, however, and factors contributing to post-treatment well-being are not well understood. This study examined whether poorer body image explained the relation between symptom severity and psychological distress. Participants (N = 70) completed the baseline assessment of a sexual health intervention study. Bootstrap methods tested body image as a mediator between bowel and GI symptom severity and two indicators of psychological distress (depressive and anxiety symptoms), controlling for relevant covariates. Measures included the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-CR38) Diarrhea, GI Symptoms, and Body Image subscales and Brief Symptom Index Depression and Anxiety subscales. Women averaged 55 years old (SD = 11.6), White (79 %), and were 4 years post-treatment. Greater Depression was related to poorer Body Image (r = -.61) and worse Diarrhea (r = .35) and GI Symptoms (r = .48). Greater Anxiety was related to poorer Body Image (r = -.42) and worse GI Symptoms (r = .45), but not Diarrhea (r = .20). Body Image mediated the effects of bowel and GI symptoms on Depression, but not on Anxiety. Long-term bowel and GI dysfunction are distressing and affect how women perceive and relate to their bodies, exacerbating survivorship difficulties. Interventions to improve adjustment post-treatment should address treatment side effects, but also target body image problems to alleviate depressive symptoms. Reducing anxiety may require other strategies. Body image may be a key modifiable factor to improve well-being in this understudied population. Longitudinal research is needed to confirm findings.

    Acute respiratory distress syndrome (ARDS) is a severe form of acute lung injury. It is a response to various diseases of variable etiology, including SARS-CoV infection. To date, a comprehensive study of the genomic physiopathology of ARDS (and SARS) is lacking, primarily due to the difficulty of finding suitable materials to study the disease process at a tissue level (instead of blood, sputa or swaps). Hereby we attempt to provide such study by analyzing autopsy lung samples from patient who died of SARS and showed different degrees of severity of the pulmonary involvement. We performed real-time quantitative PCR analysis of 107 genes with functional roles in inflammation, coagulation, fibrosis and apoptosis; some key genes were confirmed at a protein expression level by immunohistochemistry and correlated to the degree of morphological severity present in the individual samples analyzed. Significant expression levels were identified for ANPEP (a receptor for CoV), as well as inhibition of the STAT1 pathway, IFNs production and CXCL10 (a T-cell recruiter). Other genes unassociated to date with ARDS/SARS include C1Qb, C5R1, CASP3, CASP9, CD14, CD68, FGF7, HLA-DRA, IGF1, IRF3, MALAT-1, MSR1, NFIL3, SLPI, USP33, CLC, GBP1 and TAC1. As a result, we proposed to therapeutically target some of these genes with compounds such as ANPEP inhibitors, SLPI and dexamethasone. Ultimately, this study may serve as a model for future, tissue-based analyses of fibroinflammatory conditions affecting the lung.

    The incidence and outcome of the acute respiratory distress syndrome in children are not well-known, especially under current ventilatory practices. The goal of this study was to determine the incidence, etiology, and outcome of acute respiratory distress syndrome in the pediatric population in the setting of lung protective ventilation. A 1-yr, prospective, multicenter, observational study in 12 geographical areas of Spain (serving a population of 3.77 million ≤ 15 yrs of age) covered by 21 pediatric intensive care units. All consecutive pediatric patients receiving invasive mechanical ventilation and meeting American-European Consensus Criteria for acute respiratory distress syndrome. None. Data on ventilatory management, gas exchange, hemodynamics, and organ dysfunction were collected. A total of 146 mechanically ventilated patients fulfilled the acute respiratory distress syndrome definition, representing a incidence of 3.9/100,000 population ≤ 15 yrs of age/yr. Pneumonia and sepsis were the most common causes of acute respiratory distress syndrome. At the time of meeting acute respiratory distress syndrome criteria, mean PaO2/FIO2 was 99 mm Hg ± 41 mm Hg, mean tidal volume was 7.6 mL/kg ± 1.8 mL/kg predicted body weight, mean plateau pressure was 27 cm H2O ± 6 cm H2O, and mean positive end-expiratory pressure was 8.9 cm ± 2.9 cm H2O. Overall pediatric intensive care unit and hospital mortality were 26% (95% confidence interval 19.6-33.7) and 27.4% (95% confidence interval 20.8-35.1), respectively. At 24 hrs, after the assessment of oxygenation under standard ventilatory settings, 118 (80.8%) patients continued to meet acute respiratory distress syndrome criteria (PaO2/FIO2 104 mm Hg ± 36 mm Hg; pediatric intensive care units mortality 30.5%), whereas 28 patients (19.2%) had a PaO2/FIO2 >200 mm Hg (pediatric intensive care units mortality 7.1%) (p = .014).

    The 1986 Chernobyl Nuclear Power Plant accident that occurred is known as the most severe nuclear disaster in the history of humankind. Acute radiation syndrome (ARS) was diagnosed in 237 persons but only 134 of those were confirmed, including 28 patients who died due to lethal total-body gamma-irradiation and severe skin injuries caused by beta/gamma-emitting radionuclides. A small group of ARS survivors offers an interesting observational insight pertinent to the on-going discussions about long-term non-cancer effects of ionizing radiation. This descriptive study summarizes more than 20 y of follow-up, makes attempts to offer a prognosis for the Chernobyl ARS survivors' health, and explores the link between the outcomes of interest and radiation exposure.

  8. Tension Among Women in North India: An Idiom of Distress and a Cultural Syndrome.

    PubMed

    Weaver, Lesley Jo

    2017-03-01

    The existing literature on Indian ethnopsychology has long asserted that somatization is a key aspect of experiences of distress. The study of idioms of distress arose out of work done in India (Nichter in Cult Med Psychiatry 5(4):379-408, 1981), but ironically, little subsequent work has systematically explored idioms of distress in this part of the world. This ethnographic study focused on the term tension (tenśan) and its relation to a cultural syndrome among women in urban North India. This syndrome appears to involve rapid-onset anger, irritation, rumination, and sleeplessness as key symptoms. It is often linked to specific circumstances such as domestic conflict and is associated with the stresses of modern urban life. People who report more symptoms of tension had consistently higher scores on the Hopkins Symptoms Checklist-25 for depression and anxiety. In this cultural context where psychiatric care is highly stigmatized, the language of tension can aid providers of mental healthcare (many of whom, in India, are not psychiatrists or psychologists) to identify and communicate effectively with potential patients whose mental healthcare needs might otherwise go unaddressed.

  9. High or conventional positive end-expiratory pressure in adult respiratory distress syndrome.

    2014-01-01

    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.

    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. Copyright © 2013 International Society for Traumatic Stress Studies.

    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.

    Significant functional impairment and psychological distress have been observed in adolescent patients with postural orthostatic tachycardia syndrome (POTS). Interdisciplinary rehabilitation programs have been shown to be beneficial in the treatment of chronic pain in adults and adolescents. Only preliminary data have examined interdisciplinary rehabilitation efforts in patients with POTS. This study evaluated the impact of an interdisciplinary rehabilitation program on the functional impairment and psychological distress in 33 adolescents diagnosed with POTS. Patients included in the study were adolescents ages 11 to 18 diagnosed with POTS. Measures completed at admission and discharge from the program included the Functional Disability Index, Center for Epidemiological Studies-Depression-Child scale, and the Pain Catastrophizing Scale for Children. After participation in the 3-week program, adolescents with POTS demonstrated a significant increase in overall functional ability and significant reductions in depression and catastrophizing.

    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.

    Uterovaginal agenesis (Mayer-Rokitansky-Küster-Hauser Syndrome; MRKH) is a congenital nonformation of the vagina and the uterus, but with normal ovaries. The authors investigated the psychological impact of this disorder, about which very little is known. A group of 66 women with MRKH were compared with 31 control-group women on a range of self-rating scales assessing psychological distress and self-esteem. Women with MRKH had significantly more pathological scores on some of the scales and subscales, such as phobic anxiety and psychoticism (interpersonal alienation), with a similar trend for subscales measuring depression and anxiety. MRKH has a lasting negative impact on affected women's level of psychological distress and self-esteem.

    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.

    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. 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. 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. 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 change. Findings support future research

    Background: Psychiatric disorders are common in irritable bowel syndrome (IBS). We conducted this study to investigate the relationship of IBS and their subtypes with some of psychological factors. Materials and Methods: A cross-sectional study was performed among 4763 staff of Isfahan University of Medical Sciences in 2011. Modified ROME III questionnaire and Talley Bowel Disease Questionnaire were used to evaluate IBS symptoms. Hospital Anxiety and Depression Scale and 12-item General Health Questionnaire were utilized to assess anxiety, depression and psychological distress. Logistic regression analysis was used to determine the association of psychological states and IBS in the total subject and both genders. Results: About, 4763 participants with mean age 36/58 ± 8/09 were included the 2106 males and 2657 females. Three thousand and seven hundred and seventy-six (81.2%) and 2650 (57.2%) participants were married and graduated respectively. Subtype analysis of IBS and its relationship with anxiety, depression and distress comparing the two genders can be observed that: IBS and clinically-significant IBS have higher anxiety, depression symptoms, and distress than the subject without IBS (P < 0.001). Women with IBS, have higher scores than men (P < 0.001). Compared to other subtypes, mixed IBS subtype has a higher anxiety, depression, and distress score. Conclusion: A high prevalence of anxiety, depression symptoms and distress in our subjects emphasize the importance of the psychological evaluation of the patients with IBS, in order to better management of the patients and may also help to reduce the burden of health care costs.

    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. 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. 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. 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.

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.

    The aim of this study is to examine the association between optimism and psychological distress in women with breast cancer after taking into account their self-rated general health. Data were aggregated from the Scottish Health Survey (2008 to 2011) to derive a nationally representative sample of 12,255 women (11,960 cancer-free controls, and 295 breast cancer cases identified from linked cancer registry data). The explanatory variables were optimism and general health, and the outcome variable was symptoms of psychological distress. Logistic regression analyses were conducted, with optimism entered in step 1 and general health entered in step 2. In an unadjusted model, higher levels of optimism were associated with lower odds of psychological distress in both the control group (OR = 0. 57, 95 % CI = 0.51-0.60) and breast cancer group (OR = 0. 64, 95 % CI = 0.47-0.88). However, in a model adjusting for general health, optimism was associated with lower odds of psychological distress only in the control group (OR = 0.50, 95 % CI = 0.44-0.57), but not significantly in the breast cancer group (OR = 1.15, 95 % CI = 0.32-4.11). In the breast cancer group, poor general health was a stronger associate of psychological distress (OR = 4. 98, 95 % CI = 1.32-18.75). Results were consistent after adjusting for age, years since breast cancer diagnosis, survey year, socioeconomic status, education, marital status, body mass index, smoking status, and alcohol consumption. This research confirms the value of multicomponent supportive care interventions for women with breast cancer. Specifically, it suggests that following breast cancer diagnosis, health care professionals need to provide advice and signpost to services that assist women to maintain or improve both their psychological and general health.

    Background Alterations to pulmonary surfactant composition have been encountered in the Acute Respiratory Distress Syndrome (ARDS). However, only few data are available regarding the time-course and duration of surfactant changes in ARDS patients, although this information may largely influence the optimum design of clinical trials addressing surfactant replacement therapy. We therefore examined the time-course of surfactant changes in 15 patients with direct ARDS (pneumonia, aspiration) over the first 8 days after onset of mechanical ventilation. Methods Three consecutive bronchoalveolar lavages (BAL) were performed shortly after intubation (T0), and four days (T1) and eight days (T2) after intubation. Fifteen healthy volunteers served as controls. Phospholipid-to-protein ratio in BAL fluids, phospholipid class profiles, phosphatidylcholine (PC) molecular species, surfactant proteins (SP)-A, -B, -C, -D, and relative content and surface tension properties of large surfactant aggregates (LA) were assessed. Results At T0, a severe and highly significant reduction in SP-A, SP-B and SP-C, the LA fraction, PC and phosphatidylglycerol (PG) percentages, and dipalmitoylation of PC (DPPC) was encountered. Surface activity of the LA fraction was greatly impaired. Over time, significant improvements were encountered especially in view of LA content, DPPC, PG and SP-A, but minimum surface tension of LA was not fully restored (15 mN/m at T2). A highly significant correlation was observed between PaO2/FiO2 and minimum surface tension (r = -0.83; p < 0.001), SP-C (r = 0.64; p < 0.001), and DPPC (r = 0.59; p = 0.003). Outcome analysis revealed that non-survivors had even more unfavourable surfactant properties as compared to survivors. Conclusion We concluded that a profound impairment of pulmonary surfactant composition and function occurs in the very early stage of the disease and only gradually resolves over time. These observations may explain why former surfactant replacement

    In the current epidemic of Ebola virus disease, health-care workers have been transferred to Europe and the USA for optimised supportive care and experimental treatments. We describe the clinical course of the first case of Ebola virus disease contracted outside of Africa, in Madrid, Spain. Herein we report clinical, laboratory, and virological findings of the treatment of a female nurse assistant aged 44 years who was infected with Ebola virus around Sept 25-26, 2014, while caring for a Spanish missionary with confirmed Ebola virus disease who had been medically evacuated from Sierra Leone to La Paz-Carlos III University Hospital, Madrid. We also describe the use of experimental treatments for Ebola virus disease in this patient. The patient was symptomatic for 1 week before first hospital admission on Oct 6, 2014. We used supportive treatment with intravenous fluids, broad-spectrum antibiotics, and experimental treatments with convalescent plasma from two survivors of Ebola virus disease and high-dose favipiravir. On day 10 of illness, she had acute respiratory distress syndrome, possibly caused by transfusion-related acute lung injury, which was managed without mechanical ventilation. Discharge was delayed because of the detection of viral RNA in several bodily fluids despite clearance of viraemia. The patient was discharged on day 34 of illness. At the time of discharge, the patient had possible subacute post-viral thyroiditis. None of the people who had contact with the patient before and after admission became infected with Ebola virus. This report emphasises the uncertainties about the efficacy of experimental treatments for Ebola virus disease. Clinicians should be aware of the possibility of transfusion-related acute lung injury when using convalescent plasma for the treatment of Ebola virus disease. La Paz-Carlos III University Hospital.

    The aim of this study was to investigate the flow resistance and flow rate in patients with acute respiratory distress syndrome (ARDS) in the surgical intensive care unit and their relation with autonomic nervous modulation. Postoperative patients of lung or esophageal cancer surgery without ARDS were included as the control group (n = 11). Patients who developed ARDS after lung or esophageal cancer surgery were included as the ARDS group (n = 21). The ARDS patients were further divided into survivor and nonsurvivor subgroups according to their outcomes. All patients required intubation and mechanical ventilation. The flow rate was significantly decreased, while the flow resistance was significantly increased, in ARDS patients. The flow rate correlated significantly and negatively with positive end-expiratory pressure (PEEP), while the flow resistance correlated significantly and positively with PEEP in ARDS patients. Furthermore, the flow rate correlated significantly and negatively with the tidal volume-corrected normalized high-frequency power but correlated significantly and positively with the tidal volume-corrected low-/high-frequency power ratio. In contrast, the flow resistance correlated significantly and negatively with normalized very low-frequency power and tidal volume-corrected low-/high-frequency power ratio, but correlated significantly and positively with tidal volume-corrected normalized high-frequency power. The flow rate is decreased and the flow resistance increased in patients with ARDS. PEEP is one of the causes of increased flow resistance and decreased flow rate in patients with ARDS. Another cause of decreased flow rate and increased flow resistance in ARDS patients is the increased vagal activity and decreased sympathetic activity. The monitoring of flow rate and flow resistance during mechanical ventilation might be useful for the proper management of ARDS patients. Copyright © 2015. Published by Elsevier Taiwan LLC.

    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

    Repeated chest radiography is required for the diagnosis and follow-up of neonates with respiratory distress syndrome (RDS) and carries the risk of radiation hazards. Lung ultrasound (LUS) is a non-invasive bedside diagnostic tool that has proven to be effective in the diagnosis of RDS. Our aim was to assess the role of LUS with respect to the standard chest X-ray (CXR) in the detection of complications of RDS in neonates. Ninety premature newborns of both genders with RDS (mean gestational age = 29.91 ± 1.33 wk) and 40 premature babies as a control group were involved in this study. All patients underwent initial clinical assessment as well as CXR and LUS. Those who presented with respiratory distress and/or exhibited deterioration of oxygenation parameters were followed by CXR and, within 4 h, by LUS. Alveolo-interstitial syndrome and pleural line abnormalities were detected in all cases (100%) in the initial assessment, patchy consolidation was detected in 34 cases and white lung was detected in 80 cases. Alveolo-interstitial syndrome was detected in 19 controls. In follow-up of the patients, LUS was superior to CXR in detection of consolidation and sub-pleural atelectasis, but not in detection of pneumothorax. We concluded that bedside LUS is a good non-hazardous alternative tool in the early detection and follow-up of RDS in the neonatal intensive care unit; it could be of value in reducing exposure to unnecessary radiation.

    Whether upper-limb swelling is associated with axillary web syndrome (AWS) is unknown. We recruited unilateral breast cancer (BC) patients who were scheduled for surgical intervention and lymph node dissection. The pre-operative assessment and post-operative assessment 3-4 weeks after surgery evaluated the upper-limb circumferential measurements, segmental limb volume, pain scores, grasp, shoulder range of motion (ROM), shoulder muscle power and quality-of-life scores. In the control group, the peri-elbow volume and upper-arm volume were significantly higher post-operatively than pre-operatively. In the AWS group, no significant difference was found. In comparison with the control group, the AWS group had significantly more pain, less active ROM in shoulder abduction and a lower upper-limb volume at 0-10 cm proximal to the lateral epicondyle. The incidence of lymphedema was 9.9% and was not associated with AWS. AWS is a common morbidity of lymph node dissection and causes significant pain and restricted shoulder abduction in the affected limb in BC survivors. This study is the first to investigate post-operative upper-limb volumetric changes in BC survivors with and without AWS. Our findings are of great value for the clinical effect of AWS in BC survivors, for patient education, and for developing diagnostic tools for detecting AWS.

    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. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

    High-frequency oscillation is a novel form of ventilation increasingly being used to treat refractory hypoxic respiratory failure resulting from acute lung injury or acute respiratory distress syndrome. Although there is no known relationship between airway pressure and transpulmonary pressure during conventional mechanical ventilation, no study has attempted to determine transpulmonary pressure during high-frequency oscillation. BACKGROUND: High-frequency oscillation (HFO) is used for the treatment of refractory hypoxic respiratory failure. OBJECTIVE: To demonstrate that the mean transpulmonary pressure (PL) cannot be inferred from mean airway pressure (mPaw). METHODS: In seven patients already undergoing HFO for refractory acute respiratory distress syndrome, esophageal pressure (Pes) was measured using an esophageal balloon catheter. Pleural pressure (Ppl) and PL were calculated from Pes. MAIN RESULTS: In the seven patients (mean [± SD] age 59±9 years) treated with HFO at 5±1 Hz and amplitude 75±10 cmH2O, the mPaw was 27±6 cmH2O, Ppl was 9±6 cmH2O and PL was 18±11 cmH2O. Successful catheter placement and measurement of Pes occurred in 100% of subjects. There was no correlation between PL and mPaw. The majority of subjects required hemodynamic support during the use of HFO; the frequency and degree of support during the study period was no different than that before the study. CONCLUSION: The present report is the first to describe measuring Pes and calculating Ppl during HFO for acute respiratory distress syndrome. While both current guidelines and recent trials have titrated treatment based on mPaw and oxygenation, there is wide variability in PL during HFO and PL cannot be predicted from mPaw. PMID:24137575

    To determine the effect of prone positioning on ventilation distribution in children with acute respiratory distress syndrome. Prospective observational study. Paediatric Intensive Care at Red Cross War Memorial Children's Hospital, Cape Town, South Africa. Mechanically ventilated children with acute respiratory distress syndrome. Electrical impedance tomography measures were taken in the supine position, after which the child was turned into the prone position, and subsequent electrical impedance tomography measurements were taken. Thoracic electrical impedance tomography measures were taken at baseline and after 5, 20, and 60 minutes in the prone position. The proportion of ventilation, regional filling characteristics, and global inhomogeneity index were calculated for the ventral and dorsal lung regions. Arterial blood gas measurements were taken before and after the intervention. A responder was defined as having an improvement of more than 10% in the oxygenation index after 60 minutes in prone position. Twelve children (nine male, 65%) were studied. Four children were responders, three were nonresponders, and five showed no change to prone positioning. Ventilation in ventral and dorsal lung regions was no different in the supine or prone positions between response groups. The proportion of ventilation in the dorsal lung increased from 49% to 57% in responders, while it became more equal between ventral and dorsal lung regions in the prone position in nonresponders. Responders showed greater improvements in ventilation homogeneity with R improving from 0.86 ± 0.24 to 0.98 ± 0.02 in the ventral lung and 0.91 ± 0.15 to 0.99 ± 0.01 in the dorsal lung region with time in the prone position. The response to prone position was variable in children with acute respiratory distress syndrome. Prone positioning improves homogeneity of ventilation and may result in recruitment of the dorsal lung regions.

    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

    Pneumothorax is a frequent and potentially fatal complication of mechanical ventilation in patients with acute respiratory distress syndrome (ARDS). Prompt recognition and treatment of pneumothoraces is necessary to minimize morbidity and mortality. The radiologic and clinical signs of pneumothoraces in ARDS patients may have unusual and subtle features. Furthermore, small pneumothoraces in these patients can cause severe hemodynamic or pulmonary compromise. Sparse clinical literature exists on when or how to treat pneumothoraces once they develop in patients with ARDS. In this article, the authors review the pathogenesis, radiologic signs, clinical significance, and treatment of pneumothoraces in ARDS patients. Treatment options include traditional tube thoracostomy, open thoracotomy, and image-guided percutaneous catheters.

    A 52-year-old male patient who underwent multiple wedge resections experienced postoperative acute respiratory distress syndrome in both lungs after Viscum album pleurodesis. Despite initial rapid deterioration in clinical condition and rapid progression of bilateral lung infiltration, he exhibited a relatively smooth clinical recovery with marked response to glucocorticoid treatment. Our case report suggests that care must be taken to guard against the development of acute respiratory complications in the use of Viscum album for pleurodesis. However, in view of the clinically benign course, initial aggressive management of complications can prevent suffering and sequelae. PMID:28180108

    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

    Acute respiratory distress syndrome (ARDS) is a common condition in intensive care unit patients and remains a major concern, with mortality rates of around 30-45% and considerable long-term morbidity. Respiratory support in these patients must be optimized to ensure adequate gas exchange while minimizing the risks of ventilator-induced lung injury. The aim of this expert opinion document is to review the available clinical evidence related to ventilator support and adjuvant therapies in order to provide evidence-based and experience-based clinical recommendations for the management of patients with ARDS.

    Acute respiratory distress syndrome (ARDS) is a rapidly progressive hypoxemic respiratory insufficiency induced by alveolar filling mainly caused by alveolocapillary wall disruption, following direct or indirect pulmonary injury. Much less frequent in children than in adults, pediatric intensivists had long applied adult guidelines to their daily practice. In 2015, experts from the Pediatric Acute Lung Injury Consensus Conference (PALICC) published the first international guidelines specifically dedicated to pediatric ARDS. After a short summary of the history of the ARDS definition since its first report in 1967, we describe the main diagnostic and therapeutic guidelines for PALICC.

    Acute respiratory distress syndrome (ARDS) represents the ultimate pulmonary response to a wide range of injuries, from septicemia to trauma. Optimal nutrition is vital to enhancing oxygen delivery, supporting adequate cardiac contractility and respiratory musculature, eliminating fluid and electrolyte imbalances, and supporting the proinflammatory response. Research is providing a better understanding of nutrients that specifically address the complex physiologic changes in ARDS. This article highlights the pathophysiology of ARDS as it relates to nutrition, relevant nutritional assessment, and important enteral and parenteral considerations for the pediatric patient who has ARDS.

    We report on successful treatment of an 46-year-old patient with ARDS (Adult Respiratory Distress Syndrome), caused by legionella-pneumophilia-pneumonia. The treatment with conventional artifical mechanical ventilation had failed. The new method of extracorporeal CO2-Elimination and low frequency positive pressure ventilation (ECCO2-R-LFPPV), introduced by L. Gattinoni (2) was in that case of severest ARDS very helpful. Supported by antimicrobial therapy with Erythromycin and Rifampicin the lung function could be improved to "restitutio ad integrum". Changes in chest radiographs, clinical parameters of ventilation, gas exchange and haemodynamics as well as the results of sequential pulmonary studies are demonstrated and discussed.

    A suicide attempt by a 23-year-old woman involved ingestion of 1000 mL of petroleum naphtha. Early chemical pneumonitis was complicated by life-threatening, diffuse interstitial lung consolidation with pneumatoceles. Pulse steroid therapy beginning on day 17 was associated with remarkable resolution of interstitial consolidation, although an enlarging secondarily infected pneumatocele ruptured to produce a bronchopleural fistula. Thoracic surgery and antibiotic therapy resulted in improvement of the patient's respiratory condition, and she was discharged with no residual respiratory symptoms. High-dose corticosteroid therapy appears to be a useful addition to aggressive supportive treatment in late adult respiratory distress syndrome following hydrocarbon ingestion.

    Pulmonary dead-space fraction is one of few lung-specific independent predictors of mortality from acute respiratory distress syndrome. However, it is not measured routinely in clinical trials and thus altogether ignored in secondary analyses that shape future research directions and clinical practice. This study sought to validate an estimate of dead-space fraction for use in secondary analyses of clinical trials. Analysis of patient-level data pooled from acute respiratory distress syndrome clinical trials. Four approaches to estimate dead-space fraction were evaluated: three required estimating metabolic rate; one estimated dead-space fraction directly. U.S. academic teaching hospitals. Data from 210 patients across three clinical trials were used to compare performance of estimating equations with measured dead-space fraction. A second cohort of 3,135 patients from six clinical trials without measured dead-space fraction was used to confirm whether estimates independently predicted mortality. None. Dead-space fraction estimated using the unadjusted Harris-Benedict equation for energy expenditure was unbiased (mean ± SD Harris-Benedict, 0.59 ± 0.13; measured, 0.60 ± 0.12). This estimate predicted measured dead-space fraction to within ±0.10 in 70% of patients and ±0.20 in 95% of patients. Measured dead-space fraction independently predicted mortality (odds ratio, 1.36 per 0.05 increase in dead-space fraction; 95% CI, 1.10-1.68; p < 0.01). The Harris-Benedict estimate closely approximated this association with mortality in the same cohort (odds ratio, 1.55; 95% CI, 1.21-1.98; p < 0.01) and remained independently predictive of death in the larger Acute Respiratory Distress Syndrome Network cohort. Other estimates predicted measured dead-space fraction or its association with mortality less well. Dead-space fraction should be measured in future acute respiratory distress syndrome clinical trials to facilitate incorporation into secondary analyses. For analyses

    Abstract Malignant melanoma is the most aggressive form of skin cancer and carries a predisposition for metastasis to many different organs. Pulmonary dissemination is common, most often presenting as multiple discrete pulmonary nodules. While a variety of other intrathoracic patterns can occur, diffuse parenchymal infiltration causing acute respiratory failure is an extremely rare manifestation of metastatic disease. We present a case of an otherwise healthy man who developed rapidly progressive respiratory failure mimicking acute respiratory distress syndrome due to melanomatous infiltration of the lung parenchyma and airways.

    This study was designed to identify factors associated with death by 6 months post-intensive care unit (ICU) discharge and to develop a practical mortality risk score for extracorporeal membrane oxygenation (ECMO)-treated acute respiratory distress syndrome (ARDS) patients. We also assessed long-term survivors' health-related quality of life (HRQL), respiratory symptoms, and anxiety, depression and post-traumatic stress disorder (PTSD) frequencies. Data from 140 ECMO-treated ARDS patients admitted to three French ICUs (2008-2012) were analyzed. ICU survivors contacted >6 months post-ICU discharge were assessed for HRQL, psychological and PTSD status. Main ARDS etiologies were bacterial (45%), influenza A[H₁N₁] (26%) and post-operative (17%) pneumonias. Six months post-ICU discharge, 84 (60%) patients were still alive. Based on multivariable logistic regression analysis, the PRESERVE (PRedicting dEath for SEvere ARDS on VV-ECMO) score (0-14 points) was constructed with eight pre-ECMO parameters, i.e. age, body mass index, immunocompromised status, prone positioning, days of mechanical ventilation, sepsis-related organ failure assessment, plateau pressure andpositive end-expiratory pressure. Six-month post-ECMO initiation cumulative probabilities of survival were 97, 79, 54 and 16% for PRESERVE classes 0-2, 3-4, 5-6 and ≥7 (p < 0.001), respectively. HRQL evaluation in 80% of the 6-month survivors revealed satisfactory mental health but persistent physical and emotional-related difficulties, with anxiety, depression or PTSD symptoms reported, by 34, 25 or 16%, respectively. The PRESERVE score might help ICU physicians select appropriate candidates for ECMO among severe ARDS patients. Future studies should also focus on physical and psychosocial rehabilitation that could lead to improved HRQL in this population.

    According to the Dutch Guideline on Hereditary Colorectal Cancer published in 2008, patients with recently diagnosed colorectal cancer (CRC) should undergo microsatellite instability (MSI) testing by a pathologist immediately after tumour resection if they are younger than 50 years, or if a second CRC has been diagnosed before the age of 70 years, owing to the high risk of Lynch syndrome (MIPA). The aim of the present MIPAPS study was to investigate general distress and cancer-specific distress following MSI testing. From March 2007 to September 2009, 400 patients who had been tested for MSI after newly diagnosed CRC were recruited from 30 Dutch hospitals. Levels of general distress (SCL-90) and cancer-specific distress (IES) were assessed immediately after MSI result disclosure (T1) and 6 months later (T2). Response rates were 23/77 (30%) in the MSI-positive patients and 58/323 (18%) in the MSI-negative patients. Levels of general distress and cancer-specific distress were moderate. In the MSI-positive group, 27% of the patients had high general distress at T1 versus 18% at T2 (p = 0.5), whereas in the MSI-negative group, these percentage were 14 and 18% (p = 0.6), respectively. At T1 and T2, cancer-specific distress rates in the MSI-positive group and MSI-negative group were 39 versus 27% (p = 0.3) and 38 versus 36% (p = 1.0), respectively. High levels of general distress were correlated with female gender, low social support and high perceived cancer risk. Moderate levels of distress were observed after MSI testing, similar to those found in other patients diagnosed with CRC. Immediately after result disclosure, high cancer-specific distress was observed in 40% of the MSI-positive patients.

    While treatment of respiratory distress syndrome (RDS) with surfactant in premature neonates is well established, evidence for its use in non-RDS conditions, especially in the term neonate, has been less abundant. The last published review on a PubMed search was in 2001. In this review, we comprehensively and critically evaluated the evidence from the literature regarding the use of surfactant in specific non-RDS disorders in neonates. Surfactant administered as a bolus should be considered in the treatment of meconium aspiration syndrome with progressive respiratory failure. While controversial in congenital diaphragmatic hernia, it should be considered in Group B streptococcal pneumonia. As evidence evolves, we anticipate the broader application and more routine use of surfactant therapy for respiratory failure because of causes other than RDS.

    A 62-year-old woman complained of diarrhea and vomiting after receiving chemotherapy for cervical cancer in association with high doses of corticosteroids. Two months later, the patient developed acute respiratory distress syndrome, and numerous Strongyloides stercoralis parasites were found in the intrabronchial discharge. Ivermectin was administered daily until nematodes were no longer detected in the sputum, and the patient's condition was successfully rescued. Antibodies for human T-cell lymphotropic virus-1 (HTLV-1) were positive. HTLV-1 infection and the administration of corticosteroids are known risk factors for strongyloides hyperinfection syndrome. Therefore, physicians should consider this disease in the differential diagnosis of patients from endemic areas who present with gastrointestinal symptoms under these risk factors.

    Acute respiratory distress syndrome (ARDS) is a clinical syndrome characterized by alveolar flooding with protein-rich pulmonary edema fluid. Despite an improved understanding of ARDS pathogenesis, our ability to predict the development of ARDS and risk-stratify patients with the disease remains limited. Biomarkers may help identify patients at highest risk of developing ARDS, assess response to therapy, predict outcome, and optimize enrollment in clinical trials. This review begins with a general description of biomarker use in clinical medicine. We then review evidence that supports the value of various ARDS biomarkers organized by the cellular injury processes central to ARDS development: endothelial injury, epithelial injury, disordered inflammation and coagulation, fibrosis, and apoptosis. Finally, we summarize the growing contributions of genomic and proteomic research and suggest ways in which the field may evolve in the coming years.

    Acute respiratory distress syndrome (ARDS) is defined according to the criteria of the 1994 consensus conference. These criteria aim to . However, the histological criteria that correspond to ARDS are the criteria of diffuse alveolar damage described in 1976 by Katzenstein et al., which are still valid at present. In the last decade, different studies have been published that have tried to correlate the clinical syndrome with the histological findings. These studies have been basically done in experimental animals, but also by the description of the pulmonary biopsy findings and post-mortem study findings. The present article aims to show discrepancy between clinical and histological diagnosis of the acute pulmonary lesion, basically having an effect on the difficulty of the ARDS diagnosis when its origin is pulmonary and the implications of this discrepancy in the clinical practice and research.

    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.

    Acute respiratory distress syndrome (ARDS) is a form of acute life threatening respiratory failure. In daily practice there is difficulty in diagnostic and therapeutic management of Acute respiratory distress syndrome (ARDS). We observed delay in diagnostic and therapeutic procedures in patients with clinical signs for the presence of severe respiratory disorders. Finding timely evidence of the presence the clinical signs of threatening ARDS and underlying diseases like influenza A/H1N1 during prehospital period in early stage of disease it is possible introduce early adequate treatment: high flow oxygen, fluid replacement and pharmacological and antiviral therapy. This measure can reduce high mortality in patients who develop ARDS. It is important to improve diagnostic criteria for a precise definition of ARDS and transfer it in practice of emergency and family medicine, microbiology, intensive care units, hospital departments of infectious and respiratory diseases. In this article we underlined the key elements of the new definition of ARDS, diagnostic criteria and the importance of early diagnosis in prehospital period following clinical feature and course (a presence of severe dyspnea) by adding chest x-ray and laboratory investigations.

    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).

    Some studies suggest that obesity and metabolic syndrome are frequent in cancer survivors. In our country, there is a lack of documentation with regards to this problem in women. Therefore, our aim is to establish the prevalence of obesity and metabolic syndrome components in surviving Mexican women. We elected women who received treatment for cancer with a surviving = 24 months. The data evaluated were demography, clinical anthropometry, blood pressure measurement, kind of cancer, surviving time, and comorbidities, as well as glucose, cholesterol, and triglyceride levels. We studied 107 women. Their average age was 60 ± 10 years, with a surviving time of 77 ± 43 months, and a body mass index of 31 ± 6 kg/m2. Their mean glucose level was 120 ± 58 mg/dL, cholesterol 228 ± 43 mg/dL, and triglycerides 207 ± 120 mg/dL. There were 55 (51 %) with glucose > 99 mg/dL, 85 (79 %) with cholesterol > 199 mg/dL, and 67 (63 %) with triglycerides > 149 mg/dL. Obesity (body mass index = 30 kg/m2) occurred in 49 (46 %) and metabolic syndrome in 27 (26 %). Due to a high prevalence of obesity, metabolic syndrome components were frequent.

    Although there is general agreement on the characteristic features of the acute respiratory distress syndrome, we lack a scoring system that predicts acute respiratory distress syndrome outcome with high probability. Our objective was to develop an outcome score that clinicians could easily calculate at the bedside to predict the risk of death of acute respiratory distress syndrome patients 24 hours after diagnosis. A prospective, multicenter, observational, descriptive, and validation study. A network of multidisciplinary ICUs. Six-hundred patients meeting Berlin criteria for moderate and severe acute respiratory distress syndrome enrolled in two independent cohorts treated with lung-protective ventilation. None. Using individual demographic, pulmonary, and systemic data at 24 hours after acute respiratory distress syndrome diagnosis, we derived our prediction score in 300 acute respiratory distress syndrome patients based on stratification of variable values into tertiles, and validated in an independent cohort of 300 acute respiratory distress syndrome patients. Primary outcome was in-hospital mortality. We found that a 9-point score based on patient's age, PaO2/FIO2 ratio, and plateau pressure at 24 hours after acute respiratory distress syndrome diagnosis was associated with death. Patients with a score greater than 7 had a mortality of 83.3% (relative risk, 5.7; 95% CI, 3.0-11.0), whereas patients with scores less than 5 had a mortality of 14.5% (p < 0.0000001). We confirmed the predictive validity of the score in a validation cohort. A simple 9-point score based on the values of age, PaO2/FIO2 ratio, and plateau pressure calculated at 24 hours on protective ventilation after acute respiratory distress syndrome diagnosis could be used in real time for rating prognosis of acute respiratory distress syndrome patients with high probability.

    The aims of the study were to evaluate oral distress in patients with primary Sjögren's syndrome (pSS) compared with age- and sex-matched Norwegian normative data, to estimate the occurrence of oral symptoms in pSS, and to evaluate the impact of oral distress on health-related quality of life (HRQoL). The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to assess HRQoL, and the Oral Health Impact Profile 14 (OHIP-14) was used to measure oral distress. Of the 246 pSS patients invited to participate in the study, 177 (72%) responded. Data were analysed for the female participants (n = 163). Significant deviations from normative estimates were found in all OHIP-14 item results, and the findings indicated a high level of oral distress among the pSS patients. Health-related quality of life was decreased among pSS patients, with the largest deviations from normative estimates related to general health and role physical. The patients with high levels of oral distress scored significantly lower than patients with low levels of oral distress in five of the SF-36 subscales, indicating that oral conditions have a marked impact on general quality of life. In conclusion, oral distress in pSS is pronounced and severe, and should receive increased attention with a view to improving the quality of life for these patients. © 2011 Eur J Oral Sci.

    2017-01-01

    Hemoglobin (Hb) Bart's hydrops fetalis syndrome (BHFS) resulting from α0-thalassemia is considered a universally fatal disorder. However, over the last 3 decades, improvements in intrauterine interventions and perinatal intensive care have resulted in increasing numbers of BHFS survivors. We have initiated an international registry containing information on 69 patients, of which 31 are previously unpublished. In this perspective, we analyze the available clinical information to document the natural history of BHFS. In the future, once we have accrued sufficient cases, we aim to build on this study and provide information to allow counseling of at-risk couples. To date, 39 patients have survived beyond the age of 5 years, 18 of whom are now older than 10 years. Based on the available cases, we find evidence to suggest that intrauterine therapy provides benefits during the perinatal and neonatal period; however, it may not provide additional benefits to long-term growth and neurodevelopmental outcomes. Growth retardation is a major adverse long-term outcome among BHFS patients with ∼40% being severely affected in terms of weight and ∼50% in terms of height. There is also an increased risk of neurodevelopmental delay as we find 20% (11/55) of BHFS survivors suffer from a serious delay of ≥6 months. Most patients in the registry require lifelong transfusion and often have associated congenital abnormalities and comorbidities. This perspective is a first step in gathering information to allow provision of informed counseling on the predicted outcomes of affected babies. PMID:28057638

    Prior randomised trials have evaluated statins in patients with sepsis and acute respiratory distress syndrome (ARDS), but there has been no comprehensive evaluation of long-term effects, despite potential neuromuscular and mental health adverse effects of these drugs. To evaluate the effect of rosuvastatin versus placebo on survival, physical function and performance, and mental health outcomes in patients with sepsis-associated ARDS. Prospective follow-up evaluation of the ARDS Clinical Trials Network Statins for Acutely Injured Lungs from Sepsis trial of rosuvastatin versus placebo in 568 mechanically ventilated patients with sepsis-associated ARDS, with blinded 6-month outcome assessment performed in the 272 eligible survivors for age-adjusted and sex-adjusted 36-Item Short Form Health Survey (SF-36) physical function and mental health domains, and in 84 eligible survivors for the 6 min walk test, along with secondary outcomes evaluations of survival, and additional patient-reported and performance-based measures at 6-month and 12-month follow-up. Over 1-year follow-up, there was no significant difference in cumulative survival in the rosuvastatin versus placebo groups (58% vs 61%; p=0.377), with survivors demonstrating substantial impairments in physical function and mental health. Rosuvastatin versus placebo had no effect (mean treatment effect (95% CI)) on SF-36 physical function (0 (-7 to 8), p=0.939) or mental health (-6 (-12 to 1) p=0.085) domains, 6 min walk distance (per cent predicted: 2 (-9 to 14), p=0.679) or the vast majority of secondary outcomes. Over 1-year follow-up, patients with sepsis-associated ARDS had high cumulative mortality, with survivors commonly experiencing impairments in physical functioning and performance, and mental health. Randomisation to rosuvastatin had no effect on these outcomes. NCT00979121 and NCT00719446. Published by the BMJ Publishing Group Limited.

  1. Role of inflammatory mediators in the pathophysiology of acute respiratory distress syndrome.

    PubMed

    Bhatia, Madhav; Moochhala, Shabbir

    2004-02-01

    Inflammatory response leading to organ dysfunction and failure continues to be the major problem after injury in many clinical conditions such as sepsis, severe burns, acute pancreatitis, haemorrhagic shock, and trauma. In general terms, systemic inflammatory response syndrome (SIRS) is an entirely normal response to injury. Systemic leukocyte activation, however, is a direct consequence of a SIRS and if excessive, can lead to distant organ damage and multiple organ dysfunction syndrome (MODS). When SIRS leads to MODS and organ failure, the mortality becomes high and can be more than 50%. Acute lung injury that clinically manifests as acute respiratory distress syndrome (ARDS) is a major component of MODS of various aetiologies. Inflammatory mediators play a key role in the pathogenesis of ARDS, which is the primary cause of death in these conditions. This review summarizes recent studies that demonstrate the critical role played by inflammatory mediators such as tumour necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, platelet activating factor (PAF), IL-10, granulocyte macrophage-colony stimulating factor (GM-CSF), C5a, intercellular adhesion molecule (ICAM)-1, substance P, chemokines, VEGF, IGF-I, KGF, reactive oxygen species (ROS), and reactive nitrogen species (RNS) in the pathogenesis of ARDS. It is reasonable to speculate that elucidation of the key mediators in ARDS coupled with the discovery of specific inhibitors would make it possible to develop clinically effective anti-inflammatory therapy.

    Middle East respiratory syndrome coronavirus (MERS-CoV) is a novel virus that emerged in 2012, causing acute respiratory distress syndrome (ARDS), severe pneumonia-like symptoms and multi-organ failure, with a case fatality rate of ∼36%. Limited clinical studies indicate that humans infected with MERS-CoV exhibit pathology consistent with the late stages of ARDS, which is reminiscent of the disease observed in patients infected with severe acute respiratory syndrome coronavirus. Models of MERS-CoV-induced severe respiratory disease have been difficult to achieve, and small-animal models traditionally used to investigate viral pathogenesis (mouse, hamster, guinea-pig and ferret) are naturally resistant to MERS-CoV. Therefore, we used CRISPR-Cas9 gene editing to modify the mouse genome to encode two amino acids (positions 288 and 330) that match the human sequence in the dipeptidyl peptidase 4 receptor, making mice susceptible to MERS-CoV infection and replication. Serial MERS-CoV passage in these engineered mice was then used to generate a mouse-adapted virus that replicated efficiently within the lungs and evoked symptoms indicative of severe ARDS, including decreased survival, extreme weight loss, decreased pulmonary function, pulmonary haemorrhage and pathological signs indicative of end-stage lung disease. Importantly, therapeutic countermeasures comprising MERS-CoV neutralizing antibody treatment or a MERS-CoV spike protein vaccine protected the engineered mice against MERS-CoV-induced ARDS.

    The Respiratory Distress Syndrome (RDS) is one of the most frequent pathologies in the premature neonates and a major cause of morbidity and mortality. The objective of this study was to determine the association between parental smoking and the development of this syndrome. This study was an observational, longitudinal, retrospective, analytical, prolective type, with the neonates in the Neonatal Intensive Care Unit (NICU) of the Hospital Regional Monterrey (HRMI), who developed RDS (cases) and those that do not (controls), during the period January 2012 - April 2015, in both groups were determined the smoking habits of the father and the statistical analysis using SPSS (v. 14). The total sample was 85 RN, of which 46 developed SDR and 39 didn´t develop it, predominantly the genre male (56%). Seventy per cent of the group of parents who denied smoking, their children developed SDR, while 64% of parents who reported smoking, their children did not manifest this syndrome. The p-value was of 0.002, OR = 0.245, with 0.099 to 0.607 range. Parental smoking isn´t a risk factor for the development of RDS in the neonates, it could be considered a protective factor.

    A 34-year-old female presented with fever and abdominal pain. Past medical history includes Crohn's and Behcet's disease. Examination revealed multiple skin ulcerations, oral aphthae, and bilateral coarse rales. She developed respiratory distress with diffuse bilateral alveolar infiltrates on chest radiograph requiring intubation. PaO2/FiO2 ratio was 132. The chest computed tomography revealed extensive nodular and patchy ground-glass opacities. Bronchoalveolar lavage demonstrated a predominance of neutrophils. Methylprednisolone 60 mg every 6 h and broad-spectrum antimicrobials were initiated. No infectious etiologies were identified. Surgical lung biopsy demonstrated diffuse alveolar damage (DAD) mixed with lymphocytic and necrotizing vasculitis with multiple small infarcts and thrombi consistent with Behcet's vasculitis. As she improved, steroids were tapered and discharged home on oral cyclophosphamide. Pulmonary involvement in Behcet's is unusual and commonly manifests as pulmonary artery aneurysms, thrombosis, infarction, and hemorrhage. Lung biopsy findings demonstrating DAD are consistent with the clinical diagnosis of adult respiratory distress syndrome. The additional findings of necrotizing vasculitis and infarcts may have led to DAD. PMID:25378849

    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. Copyright © 2012 Elsevier Ireland Ltd.

  6. Severe acute respiratory distress syndrome caused by unintentional sewing machine lubricant ingestion: A case report

    PubMed Central

    Kishore, Sunil; Chandelia, Sudha; Patharia, Neha; Swarnim

    2016-01-01

    Sewing machine oil ingestion is rare but is possible due to its availability at home. Chemically, it belongs to hydrocarbon family which is toxic if aspirated, owing to their physical properties such as high volatility and low viscosity. On the contrary, sewing machine lubricant has high viscosity and low volatility which makes it aspiration less likely. The main danger of hydrocarbon ingestion is chemical pneumonitis which may be as severe as acute respiratory distress syndrome (ARDS). We report a case of a 5-year-old girl with accidental ingestion of sewing machine lubricant oil, who subsequently developed ARDS refractory to mechanical ventilation. There was much improvement with airway pressure release ventilation mode of ventilation, but the child succumbed to death due to pulmonary hemorrhage. PMID:27994384

    Viral infections are an important cause of pediatric acute respiratory distress syndrome (ARDS). Numerous viruses, including respiratory syncytial virus (RSV) and influenza A (H1N1) virus, have been implicated in the progression of pneumonia to ARDS; yet the incidence of progression is unknown. Despite acute and chronic morbidity associated with respiratory viral infections, particularly in "at risk" populations, treatment options are limited. Thus, with few exceptions, care is symptomatic. In addition, mortality rates for viral-related ARDS have yet to be determined. This review outlines what is known about ARDS secondary to viral infections including the epidemiology, the pathophysiology, and diagnosis. In addition, emerging treatment options to prevent infection, and to decrease disease burden will be outlined. We focused on RSV and influenza A (H1N1) viral-induced ARDS, as these are the most common viruses leading to pediatric ARDS, and have specific prophylactic and definitive treatment options.

    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.

    Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis in childhood. Respiratory symptoms can mask neurologic signs, leading to a delay in diagnosis. We report this case to highlight the diagnostic difficulty in children suffering from GBS who have respiratory involvement as the main clinical findings on presentation. This case report describes a 9-year-old girl presenting with respiratory distress, weakness, limb pain, and hypertension. The severe respiratory involvement due to a Mycoplasma pneumoniae lung infection led to a delay in diagnosing GBS in this child. Unexplained weakness, together with respiratory involvement and associated dysautonomia, should support the possibility of GBS. Copyright 2010 Elsevier Inc. All rights reserved.

    We report a unique clinical case about an 18-year-old woman, immediately post-partum after an urgent C-section, who survived severe sepsis, acute respiratory distress syndrome (ARDS) and disseminated intravascular coagulation (DIC) and was successfully treated with 11 different antibiotics, massive blood transfusions and repetitive surgeries and was on extracorporeal membrane oxygenation (ECMO) support for 22 days. Although, ECMO is a time-limited procedure and most manufacturers do not advise more than 14 days of use, the situation for this patient was life-threatening and ECMO, despite the dangerous risks listed above, was the only way to win time for the lungs to recover and for treatment of the underlying disease, while maintaining adequate oxygenation and circulation. Fortunately, the condition of this woman was stabilized and she achieved complete physical recovery, despite minor neurological deficit in the fingers of her right hand. © The Author(s) 2015.

    Six patients suffering from acute respiratory distress syndrome with the need for extracorporeal membrane oxygenation (ECMO) therapy in deep sedation were included. Isoflurane sedation with the AnaConDa system was initiated within 24 hours after initiation of ECMO therapy and resulted in a satisfactory sedation (Richmond Agitation-Sedation Scale -4 to -5). Despite deep sedation, spontaneous breathing was possible in 6 of 6 patients. We observed a reduced need for vasopressor therapy and improved lung function (PaO2, PaCO2, delta P, and tidal volume) during isoflurane sedation. Opioid consumption could be reduced, and only very low doses of isoflurane were needed (1-3 mL/h). This small case series supports the feasibility of sedation using inhaled anesthetics concurrently with venovenous ECMO.

    The polymorphonuclear leukocyte (PMN) plays an integral role in the development of permeability pulmonary edema associated with the adult respiratory distress syndrome (ARDS). This report describes 3 patients with ARDS secondary to systemic sepsis who demonstrated an abnormal diffuse accumulation of Indium (/sup 111/In)-labeled PMNs in their lungs, without concomitant clinical or laboratory evidence of a primary chest infection. In one patient, the accumulation of the pulmonary activity during an initial pass suggested that this observation was related to diffuse leukoaggregation within the pulmonary microvasculature. A 4th patient with ARDS was on high-dose corticosteroids at the time of a similar study, and showed no pulmonary accumulation of PMNs, suggesting a possible reason for the reported beneficial effect of corticosteroids in human ARDS.

  13. Clinical review: Lung imaging in acute respiratory distress syndrome patients - an update

    2013-01-01

    Over the past 30 years lung imaging has greatly contributed to the current understanding of the pathophysiology and the management of acute respiratory distress syndrome (ARDS). 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.

    Pulmonary involvement with multiple myeloma is rare. We report the case of a 61-year-old man with past medical history of chronic respiratory failure with emphysema, and a known multiple myeloma (Durie and Salmon stage III B and t(4;14) translocation). Six months after diagnosis and first line of treatment, he presented acute dyspnea with interstitial lung disease. Computed tomography showed severe bullous emphysema and diffuse, patchy, multifocal infiltrations bilaterally with nodular character, small bilateral pleural effusions, mediastinal lymphadenopathy, and a known lytic lesion of the 12th vertebra. He was treated with piperacillin-tazobactam, amikacin, oseltamivir, and methylprednisolone. Finally, outcome was unfavourable. Postmortem analysis revealed diffuse and nodular infracentimetric infiltration of the lung parenchyma by neoplastic plasma cells. Physicians should be aware that acute respiratory distress syndrome not responding to treatment of common causes could be a manifestation of the disease, even with negative BAL or biopsy and could be promptly treated with salvage therapy.

    The role of C-X-C motif chemokine 10 (CXCL10), a pro-inflammatory factor, in the development of acute respiratory distress syndrome (ARDS) remains unclear. In this study, we explored the role of CXCL10 and the effect of CXCL10 neutralization in lipopolysaccharide (LPS)-induced ARDS in rats. The expression of CXCL10 and its receptor chemokine receptor 3(CXCR3) increased after LPS induction. Moreover, neutralization of CXCL10 ameliorated the severity of ARDS by reducing pulmonary edema, inhibiting the release of inflammatory mediators (IFN-γ, IL-6 and ICAM-1) and limiting inflammatory cells (neutrophils, macrophages, CD8+ T cells) influx into the lung, with a reduction in CXCR3 expression in neutrophils and macrophages. Therefore, CXCL10 could be a potential therapeutic target in LPS-induced ARDS. PMID:28046003

    Legionella pneumophila is a common, usually underreported and undiagnosed cause of community acquired pneumonia which can lead to significant morbidity and mortality. Diffuse alveolar hemorrhage rarely have been associated with legionella infection. We present a 61-year-old man with hypertension, diabetes mellitus and obesity admitted with severe acute respiratory distress syndrome. He was found to have Legionella pneumonia with associated diffuse alveolar hemorrhage diagnosed with bronchoscopic sequential bronchoalveolar lavage. He was successfully managed with antibiotics, lung protective strategies and intravenous pulse dose steroids. This patient highlights the unusual association of Legionella infection and diffuse alveolar hemorrhage. Additionally, the case re-enforces the need for early and aggressive evaluation and management of patients presenting with pneumonia and progressive hypoxia despite adequate treatment.

  17. Argument against the Routine Use of Steroids for Pediatric Acute Respiratory Distress Syndrome

    PubMed Central

    Hartmann, Silvia M.; Hough, Catherine L.

    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.

    Adenovirus infections are associated with respiratory (especially upper respiratory) infection and gastrointestinal disease and occur primarily in infants and children. Although rare in adults, severe lower respiratory adenovirus infections including pneumonia are reported in specific populations, such as military recruits and immunocompromised patients. Antiviral treatment is challenging due to limited clinical experience and lack of well-controlled randomized trials. Several previously reported cases of adenoviral pneumonia showed promising efficacy of cidofovir. However, few reports discussed the efficacy of cidofovir in acute respiratory distress syndrome (ARDS). We experienced 3 cases of adenoviral pneumonia associated with ARDS and treated with cidofovir and respiratory support, including extracorporeal membrane oxygenation (ECMO). All 3 patients showed a positive clinical response to cidofovir and survival at 28 days. Cidofovir with early ECMO therapy may be a therapeutic option in adenoviral ARDS. A literature review identified 15 cases of adenovirus pneumonia associated with ARDS.

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. 2014 BMJ Publishing Group Ltd.

    To estimate direct medical costs (DMC) associated with treatment of Respiratory Distress Syndrome (RDS) in newborns (NB) in two specialized public hospitals in Mexico. The perspective used was health care payer. We estimated DMC associated with RDS management. The pattern of resource use was established by reviewing clinical records. Microcosting and bootstrap techniques were used to obtain the DMC. Estimated costs were reported in 2011 US dollars. Average DMC per RDS event was 14 226 USD. The most significant items that account for this cost were hospitalization (38%), laboratory and diagnostic exams (18%), incubator time (10%), surfactant therapy (7%), and mechanical ventilation (7%). Average DMC in NB with RDS fluctuated in relation to gestational age weight at birth and clinical complications presented by patients during their hospitalization.

    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.

Case 1 demonstrated acute respiratory symptoms during the work of distortion correction of iron boards, coated with a rust preventative including rich zinc using an acetylene gas burner. 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.

  5. The role of ventilation-induced surfactant dysfunction and atelectasis in causing acute respiratory distress syndrome.

    PubMed

    2012-04-01

    This Pulmonary Perspective describes a new pathophysiologic scenario by which the acute respiratory distress syndrome (ARDS) might develop, summarizes the literature on which this new scenario is based, and discusses the resulting implications with respect to patient management. Rather than ARDS occurring as a result of the inflammatory response associated with predisposing risk factors, the proposed scenario theorizes that the initiating problem is atelectasis that develops as a result of a surfactant abnormality that is caused by spontaneous or mechanical ventilation, together with our current approaches to patient positioning and sedation. The proposed pathophysiology implies that ventilation-induced lung injury occurs before, and causes, ARDS (rather than developing after the fact and only serving to magnify the existing injury) and that some instances of ARDS are iatrogenic. If the proposed scenario is correct, it also implies that at least some instances of ARDS might be prevented by implementing a number of simple, safe modifications in patient care.

    Acute respiratory distress syndrome (ARDS) is still related to high mortality and morbidity rates. Most patients with ARDS will require ventilatory support. This treatment has a direct impact upon patient outcome and is associated to major side effects. In this regard, ventilator-associated lung injury (VALI) is the main concern when this technique is used. The ultimate mechanisms of VALI and its management are under constant evolution. The present review describes the classical mechanisms of VALI and how they have evolved with recent findings from physiopathological and clinical studies, with the aim of analyzing the clinical implications derived from them. Lastly, a series of knowledge-based recommendations are proposed that can be helpful for the ventilator assisted management of ARDS at the patient bedside.

Retrospective observational study. Medical, surgical, trauma, and cardiovascular ICUs of an academic medical center. A total of 1,080 critically ill patients with sepsis. None. The unadjusted occurrence rate of acute respiratory distress syndrome within 96 hours of ICU admission was 35% among patients who had received oral corticosteroids compared with 42% among those who had not (p = 0.107). In a multivariable analysis controlling for prespecified confounders, preadmission oral corticosteroids were associated with a lower incidence of acute respiratory distress syndrome in the 96 hours after ICU admission (odds ratio, 0.53; 95% CI, 0.33-0.84; p = 0.008), a finding that persisted in multiple sensitivity analyses. The median daily dose of oral corticosteroids among the 165 patients receiving oral corticosteroids, in prednisone equivalents, was 10 mg (interquartile range, 5-30 mg). Higher doses of preadmission oral corticosteroids were associated with a lower incidence of acute respiratory distress syndrome (odds ratio for 30 mg of prednisone compared with 5 mg 0.53; 95% CI, 0.32-0.86). In multivariable analyses, preadmission oral corticosteroids were not associated with in-hospital mortality (odds ratio, 1.41; 95% CI, 0.87-2.28; p = 0.164), ICU length of stay (odds ratio, 0.90; 95% CI, 0.63-1.30; p = 0.585), or ventilator-free days (odds ratio, 1.06; 95% CI, 0.71-1.57; p = 0.783). Among ICU patients with sepsis, preadmission oral corticosteroids were independently associated with a lower incidence of early acute respiratory distress syndrome.

    Acute respiratory distress syndrome (ARDS) is a serious complication of sepsis, and sepsis-associated ARDS is associated with significant morbidity and mortality. To date, no study has directly examined the epidemiology of ARDS in severe sepsis from the earliest presentation to the health care system, the emergency department (ED). This was a single-center retrospective, observational cohort study of 778 adults with severe sepsis presenting to the ED. The primary outcome was the development of ARDS requiring mechanical ventilation during the first 5 hospital days. Acute respiratory distress syndrome was defined using the Berlin definition. We used multivariable logistic regression to identify risk factors associated independently with ARDS development. The incidence of ARDS was 6.2% (48/778 patients) in the entire cohort. Acute respiratory distress syndrome development varied across the continuum of care: 0.9% of patients fulfilled criteria for ARDS in the ED, 1.4% admitted to the ward developed ARDS, and 8.9% admitted to the intensive care unit developed ARDS. Acute respiratory distress syndrome developed a median of 1 day after admission and was associated with a 4-fold higher risk of in-hospital mortality (14% vs. 60%, P < 0.001). Independent risk factors associated with increased risk of ARDS development included intermediate (2-3.9 mmol/L) (P = 0.04) and high (≥4) serum lactate levels (P = 0.008), Lung Injury Prediction score (P < 0.001), and microbiologically proven infection (P = 0.01). In patients presenting to the ED with severe sepsis, the rate of sepsis-associated ARDS development varied across the continuum of care. Acute respiratory distress syndrome developed rapidly and was associated with significant mortality. Elevated serum lactate levels in the ED and a recently validated clinical prediction score were independently associated with the development of ARDS in severe sepsis.

    Mechanical ventilation is an essential therapy in the treatment of respiratory failure in preterm infants. However, optimal ventilation strategy continues to be difficult to define. To compare the effects of volume guarantee (VG) combined with intermittent mandatory ventilation (SIMV) and VG combined with pressure support ventilation (PSV) on the pulmonary mechanics and short term prognosis in preterm infants with respiratory distress syndrome. Infants of <32 weeks gestational age ventilated for respiratory distress syndrome were randomized to receive either SIMV + VG or PSV + VG. The patient characteristics, ventilator variables including PIP, PEEP, MAP, VT, dynamic compliance, resistance, C20/C, and neonatal outcomes (IVH, ROP, oxygen dependency at 28th postnatal day and 36 weeks of PMA), mortality and extubation failure were recorded in each groups. Thirty-four infants were enrolled in to the study: 19 patients were randomized to the SIMV + VG group, and 15 patients to the PSV + VG group. No significant differences were observed between the two groups in terms of the birth weight, gestational age, gender, multiple pregnancy, delivery mode, and antenatal steroid treatment. The respiratory and ventilatory parameters were similar in the groups. The need for reintubation were common in SIMV + VG group (P < 0.01). Volume guaranteed ventilation combined with PSV may be a convenient method for preterm infants with RDS in terms of reducing postextubation atelectasis and the need for reintubation.

    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

    Acute respiratory distress syndrome (ARDS) is the leading cause of death in critical care medicine. The syndrome is typified by an exaggerated inflammatory response within the lungs. ARDS has been reported in many species, including dogs. We have previously reported a fatal familial juvenile respiratory disease accompanied by occasional unilateral renal aplasia and hydrocephalus, in Dalmatian dogs. The condition with a suggested recessive mode of inheritance resembles acute exacerbation of usual interstitial pneumonia in man. We combined SNP-based homozygosity mapping of two ARDS-affected Dalmatian dogs and whole genome sequencing of one affected dog to identify a case-specific homozygous nonsense variant, c.31C>T; p.R11* in the ANLN gene. Subsequent analysis of the variant in a total cohort of 188 Dalmatians, including seven cases, indicated complete segregation of the variant with the disease and confirmed an autosomal recessive mode of inheritance. Low carrier frequency of 1.7% was observed in a population cohort. The early nonsense variant results in a nearly complete truncation of the ANLN protein and immunohistochemical analysis of the affected lung tissue demonstrated the lack of the membranous and cytoplasmic staining of ANLN protein in the metaplastic bronchial epithelium. The ANLN gene encodes an anillin actin binding protein with a suggested regulatory role in the integrity of intercellular junctions. Our study suggests that defective ANLN results in abnormal cellular organization of the bronchiolar epithelium, which in turn predisposes to acute respiratory distress. ANLN has been previously linked to a dominant focal segmental glomerulosclerosis in human without pulmonary defects. However, the lack of similar renal manifestations in the affected Dalmatians suggest a novel ANLN-related pulmonary function and disease association. PMID:28222102

    In the prone position, computed tomography scan densities redistribute from dorsal to ventral as the dorsal region tends to reexpand while the ventral zone tends to collapse. Although gravitational influence is similar in both positions, dorsal recruitment usually prevails over ventral derecruitment, because of the need for the lung and its confining chest wall to conform to the same volume. The final result of proning is that the overall lung inflation is more homogeneous from dorsal to ventral than in the supine position, with more homogeneously distributed stress and strain. As the distribution of perfusion remains nearly constant in both postures, proning usually improves oxygenation. Animal experiments clearly show that prone positioning delays or prevents ventilation-induced lung injury, likely due in large part to more homogeneously distributed stress and strain. Over the last 15 years, five major trials have been conducted to compare the prone and supine positions in acute respiratory distress syndrome, regarding survival advantage. The sequence of trials enrolled patients who were progressively more hypoxemic; exposure to the prone position was extended from 8 to 17 hours/day, and lung-protective ventilation was more rigorously applied. Single-patient and meta-analyses drawing from the four major trials showed significant survival benefit in patients with PaO2/FiO2 lower than 100. The latest PROSEVA (Proning Severe ARDS Patients) trial confirmed these benefits in a formal randomized study. The bulk of data indicates that in severe acute respiratory distress syndrome, carefully performed prone positioning offers an absolute survival advantage of 10-17%, making this intervention highly recommended in this specific population subset.

    Background: Obstructive sleep apnea (OSA) may increase the risk of respiratory complications and acute respiratory distress syndrome (ARDS) among surgical patients. OSA is more prevalent among obese individuals; obesity can predispose to ARDS. Hypothesis: It is unclear whether OSA independently contributes towards the risk of ARDS among hospitalized patients. Methods: This is a pre-planned retrospective subgroup analysis of the prospectively identified cohort of 5,584 patients across 22 hospitals with at least one risk factor for ARDS at the time of hospitalization from a trial by the US Critical Illness and Injury Trials Group designed to validate the Lung Injury Prediction Score. A total of 252 patients (4.5%) had a diagnosis of OSA at the time of hospitalization; of those, 66% were obese. Following multivariate adjustment in the logistic regression model, there was no significant relationship between OSA and development of ARDS (OR = 0.65, 95%CI = 0.32-1.22). However, body mass index (BMI) was associated with subsequent ARDS development (OR = 1.02, 95%CI = 1.00-1.04, p = 0.03). Neither OSA nor BMI affected mechanical ventilation requirement or mortality. Conclusions: Prior diagnosis of OSA did not independently affect development of ARDS among patients with at least one predisposing condition, nor the need for mechanical ventilation or hospital mortality. Obesity appeared to independently increase the risk of ARDS. Citation: Karnatovskaia LV, Lee AS, Bender SP, Talmor D, Festic E.

    To discuss the rationale, hypothesis, modality of extracorporeal blood purification (EBP) techniques for the critically ill animal models or patients, and to summarize the experimental and clinical studies with inconsistent data which explored the EBP's efficacy in the areas of critical care medicine. Articles referred in this review were collected from the database of PubMed published in English up to June 2014. We had done a literature search by using the term "(sepsis OR acute lung injury OR acute respiratory distress syndrome) AND (extracorporeal blood purification OR hemofiltration OR hemoperfusion OR plasma exchange OR plasmapheresis OR adsorpiton)". Related original or review articles were included and carefully analyzed. Acute cellular and humoral immune disturbances occur in both sepsis and acute respiratory distress syndrome (ARDS). Treatments aimed at targeting one single pro-/anti-inflammatory mediator have largely failed with no proven clinical benefits. Such failure shifts the therapeutic rationale to the nonspecific, broad-spectrum methods for modulating the over-activated inflammatory and anti-inflammatory response. Therefore, EBP techniques have become the potential weapons with high promise for removing the circulating pro-/anti-inflammatory mediators and promoting immune reconstitution. Over the years, multiple extracorporeal techniques for the critically ill animal models or patients have been developed, including hemofiltration (HF), high-volume hemofiltration (HVHF), high-cutoff hemofiltration (HCO-HF), hemo-perfusion or -adsorption (HP/HA), coupled plasma filtration adsorption (CPFA), and plasma exchange (PE). These previous studies showed that EBP therapy was feasible and safe for the critically ill animal models or patients. However, data on their efficacy (especially on the clinical benefits, such as mortality) were inconsistent. It is not now to conclude that EBP intervention can purify septic or ARDS patients with high clinical efficacy

    Objectives Children with an immunocompromised condition and requiring invasive mechanical ventilation have high risk of death. Such patients are commonly transitioned to rescue modes of non-conventional ventilation, including airway pressure release ventilation and high-frequency oscillatory ventilation, for acute respiratory distress syndrome refractory to conventional ventilation. Our aim was to describe our experience with airway pressure release ventilation and high-frequency oscillatory ventilation in children with an immunocompromised condition and acute respiratory distress syndrome refractory to conventional ventilation and to identify factors associated with survival. Design Retrospective cohort study. Setting Tertiary care, university-affiliated PICU. Patients Sixty pediatric patients with an immunocompromised condition and acute respiratory distress syndrome refractory to conventional ventilation transitioned to either airway pressure release ventilation or high-frequency oscillatory ventilation. Interventions None. Measurements and Main Results Demographic data, ventilator settings, arterial blood gases, oxygenation index, and Pao2/Fio2 were recorded before transition to either mode of nonconventional ventilation and at predetermined intervals after transition for up to 5 days. Mortality in the entire cohort was 63% and did not differ between patients transitioned to airway pressure release ventilation and high-frequency oscillatory ventilation. For both airway pressure release ventilation and high-frequency oscillatory ventilation, improvements in oxygenation index and Pao2/Fio2 at 24 hours expressed as a fraction of pretransition values (oxygenation index24/oxygenation indexpre and Pao2/Fio224/Pao2/FIO2pre) reliably discriminated nonsurvivors from survivors, with receiver operating characteristic areas under the curves between 0.89 and 0.95 (p for all curves < 0.001).

    Objective To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors. Methods The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured questionnaire over the phone. Post-poliomyelitis syndrome (PPS) was identified according to the specified diagnostic criteria. Differences between polio survivors with or without PPS were evaluated, and the risk factors for PPS were analyzed by the odds ratio (OR). Results Majority of polio survivors were middle-aged and mean age was 51.2±8.3 years. A total of 188 out of 313 polio survivors met the adopted criteria for PPS based on the symptoms, yielding a prevalence of 61.6%. Mean interval between acute poliomyelitis and the development of PPS was 38.5±11.6 years. Female gender (OR 1.82; confidence interval [CI] 1.09-3.06), the age at onset of poliomyelitis (OR 1.75; CI 1.05-2.94), the use of orthoses or walking aids (OR 2.46; CI 1.44-4.20), and the history of medical treatment for paralysis, pain or gait disturbance (OR 2.62; CI 1.52-4.51) represented independent risk factors for PPS. Conclusion We found that the majority of Korean polio survivors entered middle age with many medical, functional, and social problems. Female gender, early age of onset of poliomyelitis, the use of orthoses or walking aids, and the history of medical treatment for paralysis, pain or gait disturbance were identified as the significant risk factors for PPS. A comprehensive and multidisciplinary plan should be prepared to manage polio survivors considering their need for health care services and the risk factors for late effects, such as PPS.

    Despite growing evidence in support of mindfulness as an underlying mechanism of mindfulness-based interventions (MBIs), it has been suggested that nonspecific therapeutic factors, such as the experience of social support, may contribute to the positive effects of MBIs. In the present study, we examined whether change in mindfulness and/or social support mediated the effect of Mindfulness-Based Cancer Recovery (MBCR) compared to another active intervention (i.e. Supportive Expressive Group Therapy (SET)), on change in mood disturbance, stress symptoms and quality of life. A secondary analysis was conducted of a multi-site randomized clinical trial investigating the impacts of MBCR and SET on distressed breast cancer survivors (MINDSET). We applied the causal steps approach with bootstrapping to test mediation, using pre- and post-intervention questionnaire data of the participants who were randomised to MBCR (n = 69) or SET (n = 70). MBCR participants improved significantly more on mood disturbance, stress symptoms and social support, but not on quality of life or mindfulness, compared to SET participants. Increased social support partially mediated the impact of MBCR versus SET on mood disturbance and stress symptoms. Because no group differences on mindfulness and quality of life were observed, no mediation analyses were performed on these variables. Findings showed that increased social support was related to more improvement in mood and stress after MBCR compared to support groups, whereas changes in mindfulness were not. This suggests a more important role for social support in enhancing outcomes in MBCR than previously thought.

    This case report summarizes the first use of intravenous vitamin C employed as an adjunctive interventional agent in the therapy of recurrent acute respiratory distress syndrome (ARDS). The two episodes of ARDS occurred in a young female patient with Cronkhite-Canada syndrome, a rare, sporadically occurring, noninherited disorder that is characterized by extensive gastrointestinal polyposis and malabsorption. Prior to the episodes of sepsis, the patient was receiving nutrition via chronic hyperalimentation administered through a long-standing central venous catheter. The patient became recurrently septic with Gram positive cocci which led to two instances of ARDS. This report describes the broad-based general critical care of a septic patient with acute respiratory failure that includes fluid resuscitation, broad-spectrum antibiotics, and vasopressor support. Intravenous vitamin C infused at 50 mg per kilogram body weight every 6 hours for 96 hours was incorporated as an adjunctive agent in the care of this patient. Vitamin C when used as a parenteral agent in high doses acts “pleiotropically” to attenuate proinflammatory mediator expression, to improve alveolar fluid clearance, and to act as an antioxidant.

    2014-02-01

    To analyze recently published articles in the medical literature that studied distinct aspects of adult patients with acute respiratory distress syndrome (ARDS) after the new Berlin definition introduced in 2012. The degree of ARDS severity according to this new classification correlated well with extravascular lung water index, pulmonary vascular permeability index and the finding of diffuse alveolar damage on autopsy. The new possibility of bedside echocardiographic evaluation of biventricular cardiac function is indicating the necessity of including a subgroup of severity of patients with right ventricular dysfunction. High-resolution CT evaluation showed that signs of pulmonary fibroproliferation in early ARDS predict increased ventilator dependency, multiple organ failure and mortality. The median development of ARDS 1 or 2 days after hospital admission emphasizes the need for ARDS intrahospital prevention, especially protective ventilation in non-ARDS patients. The better outcome with the use of prone position in patients with PaO2/FIO2 below 150 recently observed questioned the Berlin definition thresholds to decide the future best treatment strategies according to the proposed degree of severity of the syndrome. The impact of the Berlin definition of ARDS on the incidence, better treatment stratification and mortality ratio of ARDS is still to be determined.

    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.

    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. Copyright © 2015.

    Acute respiratory distress syndrome (ARDS) is associated with significant mortality and morbidity in survivors. Treatment is only supportive, therefore elucidating modifiable factors that could prevent ARDS could have a profound impact on outcome. The impact that sepsis-associated cardiac dysfunction has on ARDS is not known. In this retrospective observational cohort study of mechanically ventilated patients with severe sepsis and septic shock, 122 patients were assessed for the impact of sepsis-associated cardiac dysfunction on incidence of ARDS (primary outcome) and mortality. Sepsis-associated cardiac dysfunction occurred in 44 patients (36.1%). There was no association of sepsis-associated cardiac dysfunction with ARDS incidence (p= 0.59) or mortality, and no association with outcomes in patients that did progress to ARDS after admission. Multivariable logistic regression demonstrated that higher BMI was associated with progression to ARDS (adjusted OR 11.84, 95% CI 1.24 to 113.0, p= 0.02). Cardiac dysfunction in mechanically ventilated patients with sepsis did not impact ARDS incidence, clinical outcome in ARDS patients, or mortality. This contrasts against previous investigations demonstrating an influence of nonpulmonary organ dysfunction on outcome in ARDS. Given the frequency of ARDS as a sequela of sepsis, the impact of cardiac dysfunction on outcome should be further studied. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. Psychological distress of patients suffering from restless legs syndrome: a cross-sectional study

    2011-01-01

    Background Restless legs syndrome (RLS) is a chronic disorder with substantial impact on quality of life similar to that seen in diabetes mellitus or osteoarthritis. Little is known about the psychological characteristics of RLS patients although psychological factors may contribute to unfavourable treatment outcome. Methods In an observational cross-sectional design, we evaluated the psychological features of 166 consecutive RLS patients from three outpatient clinics, by means of the Symptom Checklist 90-R (SCL-90-R) questionnaire. Additionally, the Beck Depression Inventory-II (BDI-II) and the International RLS Severity Scale (IRLS) were measured. Both treated and untreated patients were included, all patients sought treatment. Results Untreated patients (n = 69) had elevated but normal scores on the SCL-90-R Global Severity Index (GSI; p = 0.002) and on the sub-scales somatisation (p < 0.001), compulsivity (p = 0.003), depression (p = 0.02), and anxiety (p = 0.004) compared with a German representative sample. In the treated group, particularly in those patients who were dissatisfied with their actual treatment (n = 62), psychological distress was higher than in the untreated group with elevated scores for the GSI (p = 0.03) and the sub-scales compulsivity (p = 0.006), depression (p = 0.012), anxiety (p = 0.031), hostility (p = 0.013), phobic anxiety (p = 0.024), and paranoid ideation (p = 0.012). Augmentation, the most serious side effect of dopaminergic, i.e. first-line treatment of RLS, and loss of efficacy were accompanied with the highest psychological distress, as seen particularly in the normative values of the sub-scales compulsivity and anxiety. Generally, higher RLS severity was correlated with higher psychological impairment (p < 0.001). Conclusion Severely affected RLS patients show psychological impairment in multiple psychological domains which has to be taken into account in the treatment regimen. PMID:21933380

    The aim of the present study was to compare the effectiveness of different modes of mechanical ventilation in combination with secretolytic therapy with ambroxol in premature infants with respiratory distress syndrome. Seventy-three premature infants with hyaline membrane disease (HMD) (stage III–IV), also known as respiratory distress syndrome, who were supported by mechanical ventilation in the neonatal intensive care unit (NICU) of Xuzhou Central Hospital, were involved in the present study, between January 2013 and February 2015. Forty cases were randomly selected and treated with high frequency oscillatory ventilation (HFOV), forming the HFOV group, whereas 33 cases were selected and treated with conventional mechanical ventilation (CMV), forming the CMV group. Patients in the two groups were administered ambroxol intravenously at a dosage rate of 30 mg/kg body weight at the beginning of the study. The present study involved monitoring the blood gas index as well as changes in the respiratory function index in the two groups. Additionally, the incidence of complications in the premature infants in the two groups was observed prior to and following the ventilation. Pulmonary arterial oxygen tension (PaO2), the PaO2/fraction of inspired oxygen (FiO2) ratio, the oxygenation index [OI = 100 × mean airway pressure (MAP) × FiO2/PaO2], as well as the arterial/alveolar oxygen partial pressure ratio (a/APO2) = PaO2/(713 × FiO2 partial pressure of carbon dioxide (PaCO2)/0.8) of the patients in the HFOV group after 1, 12 and 24 h of treatment were significantly improved as compared to the patients of the CMV group. However, there was no significant difference between patients in the two groups with regard to the number of mortalities, complications such as pneumothorax, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), and the time of ventilation. In conclusion, combining HFOV

    Chlorine inhalation can result in significant morbidity and mortality. The most common clinical ramification is mucosal irritation. Rarely, depending upon the degree of exposure, patients can develop acute respiratory distress syndrome. Management is usually supportive with an unproven role for inhaled or systemic corticosteroids. A case of a young woman who developed respiratory failure secondary to acute respiratory distress syndrome from accidental exposure to chlorine fumes at a community swimming pool is described. The patient suffered a prolonged hospitalization with the need for mechanical ventilation. Despite limited data to support the decision, the patient was started on treatment with corticosteroids. She recovered completely from her illness and was discharged home without supplemental oxygen. A concise discussion of chlorine inhalation injury and a literature review on the utility of inhaled and/or systemic corticosteroids for this clinical entity is presented.

    It has been proved that spontaneous breathing (SB) with biphasic positive airway pressure (BIPAP) can improve lung aeration in acute respiratory distress syndrome compared with controlled mechanical ventilation. The authors hypothesized that SB with BIPAP would attenuate lung injury in acute respiratory distress syndrome compared with pressure-controlled ventilation. Twenty male New Zealand white rabbits with hydrochloric acid aspiration-induced acute respiratory distress syndrome were randomly ventilated using the BIPAP either with SB (BIPAP plus SB group) or without SB (BIPAP minus SB group) for 5 h. Inspiration pressure was adjusted to maintain the tidal volume at 6 ml/kg. Both groups received the same positive end-expiratory pressure level at 5 cm H2O for hemodynamic goals. Eight healthy animals without ventilatory support served as the control group. The BIPAP plus SB group presented a lower ratio of dead space ventilation to tidal volume, a lower respiratory rate, and lower minute ventilation. No significant difference in the protein levels of interleukin-6 and interleukin-8 in plasma, bronchoalveolar lavage fluid, and lung tissue were measured between the two experimental groups. However, SB resulted in lower messenger ribonucleic acid levels of interleukin-6 (mean ± SD; 1.8 ± 0.7 vs. 2.6 ± 0.5; P = 0.008) and interleukin-8 (2.2 ± 0.5 vs. 2.9 ± 0.6; P = 0.014) in lung tissues. In addition, lung histopathology revealed less injury in the BIPAP plus SB group (lung injury score, 13.8 ± 4.6 vs. 21.8 ± 5.7; P < 0.05). In hydrochloric acid-induced acute respiratory distress syndrome, SB with BIPAP attenuated lung injury and improved respiratory function compared with controlled ventilation with low tidal volume.

    A woman aged 61 years presented to the emergency room with a 1-week history of dyspnoea on exertion and dry cough. X-ray of the chest showed diffuse interstitial opacities and was started on antibiotics and furosemide, and despite these measures, patient's respiratory status worsened, prompting endotracheal intubation. CT of the chest showed diffuse bilateral ground glass opacities and underwent bronchoscope with trans-bronchial biopsy that showed chronic bronchitis. Pt was empirically started on intravenous steroids due to concerns for interstitial lung disease (ILD). Autoimmune work up was sent and underwent video-assisted thoracoscopic surgery-guided biopsy of the lung that showed non-specific interstitial pattern with fibrosis. The patient was diagnosed as having antisynthetase syndrome with pulmonary involvement (ILD) as the cause of her acute respiratory failure. Azathioprine was started as steroid-sparing agent and was weaned off the ventilator to a tracheostomy collar and discharged to long-term rehabilitation centre.

    One of the most challenging problems in critical care medicine is the management of patients with the acute respiratory distress syndrome. Increasing evidence from experimental and clinical studies suggests that mechanical ventilation, which is necessary for life support in patients with acute respiratory distress syndrome, can cause lung fibrosis, which may significantly contribute to morbidity and mortality. The role of mechanical stress as an inciting factor for lung fibrosis versus its role in lung homeostasis and the restoration of normal pulmonary parenchymal architecture is poorly understood. In this review, the authors explore recent advances in the field of pulmonary fibrosis in the context of acute respiratory distress syndrome, concentrating on its relevance to the practice of mechanical ventilation, as commonly applied by anesthetists and intensivists. The authors focus the discussion on the thesis that mechanical ventilation-or more specifically, that ventilator-induced lung injury-may be a major contributor to lung fibrosis. The authors critically appraise possible mechanisms underlying the mechanical stress-induced lung fibrosis and highlight potential therapeutic strategies to mitigate this fibrosis.

    Objective Persistent fatigue and depressive symptoms are both highly prevalent among patients with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) as well as breast cancer survivors. This study aimed to assess and directly compare perceptions of fatigue as highly interfering in one’s daily functioning in both patient populations to better understand their relationships with depressed mood. Methods Participants were 95 female CFS/ME patients and 67 females who were approximately 5 years post-treatment for stage 0-III breast cancer presenting with clinically elevated fatigue severity. Self-report measures were obtained on participants’ fatigue-related interference in daily functioning and fatigue severity as well as depressed mood. Hierarchical regression was used to test effects controlling for relevant demographic, psychosocial, and medical covariates. Results CFS/ME patients endorsed greater depressed mood and fatigue interference than did fatigued breast cancer survivors, p’s<.001. These factors were significantly positively correlated among CFS/ME patients (β=.36, p<.001), but not the fatigued breast cancer survivors (β=.18, p=.19). Conclusions CFS/ME patients reported elevated fatigue symptoms and depression relative to fatigued breast cancer survivors. In the former group, greater depressed mood was highly and significantly associated with greater fatigue-related inference in daily activities. Potential targets for cognitive behavioral interventions are discussed. PMID:26180660

    The vascular endothelium separates circulating fluid and inflammatory cells from the surrounding tissues. Vascular leak occurs in response to wide-spread inflammatory processes, such as sepsis and acute respiratory distress syndrome, because of the formation of gaps between endothelial cells. Although these disorders are leading causes of mortality in the intensive care unit, no medical therapies exist to restore endothelial cell barrier function. Recent evidence highlights a key role for the Abl family of nonreceptor tyrosine kinases in regulating vascular barrier integrity. These kinases have well-described roles in cancer progression and neuronal morphogenesis, but their functions in the vasculature have remained enigmatic until recently. The Abl family kinases, c-Abl (Abl1) and Abl related gene (Arg, Abl2), phosphorylate several cytoskeletal effectors that mediate vascular permeability, including nonmuscle myosin light chain kinase, cortactin, vinculin, and β-catenin. They also regulate cell-cell and cell-matrix junction dynamics, and the formation of actin-based cellular protrusions in multiple cell types. In addition, both c-Abl and Arg are activated by hyperoxia and contribute to oxidant-induced endothelial cell injury. These numerous roles of Abl kinases in endothelial cells and the current clinical usage of imatinib and other Abl kinase inhibitors have spurred recent interest in repurposing these drugs for the treatment of vascular barrier dysfunction. This review will describe the structure and function of Abl kinases with an emphasis on their roles in mediating vascular barrier integrity. We will also provide a critical evaluation of the potential for exploiting Abl kinase inhibition as a novel therapy for inflammatory vascular leak syndromes. © 2015 American Heart Association, Inc.

    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.

  17. The role of inhaled prostacyclin in treating acute respiratory distress syndrome.

    Acute respiratory distress syndrome (ARDS) is a syndrome of acute lung injury that is characterized by noncardiogenic pulmonary edema and severe hypoxemia second to a pathogenic impairment of gas exchange. Despite significant advances in the area, mortality remains high among ARDS patients. High mortality and a limited spectrum of therapeutic options have left clinicians searching for alternatives, spiking interest in selective pulmonary vasodilators (SPVs). Despite the lack of robust evidence, SPVs are commonly employed for their therapeutic role in improving oxygenation in patients who have developed refractory hypoxemia in ARDS. While inhaled epoprostenol (iEPO) also impacts arterial oxygenation by decreasing ventilation-perfusion (V/Q) mismatching and pulmonary shunt flow, this effect is not different from inhaled nitric oxide (iNO). The most effective and safest dose for yielding a clinically significant increase in PaO2 and reduction in pulmonary artery pressure (PAP) appears to be 20-30 ng/kg/min in adults and 30 ng/kg/min in pediatric patients. iEPO appears to have a ceiling effect above these doses in which no additional benefit may be derived. iNO and iEPO have shown similar efficacy profiles; however, they differ with respect to cost and ease of therapeutic administration. The most beneficial effects of iEPO have been seen in adult patients with secondary ARDS as compared with primary ARDS, most likely due to the difference in etiology of the two disease states, and in patients suffering from baseline right ventricular heart failure. Although iEPO has demonstrated improvements in hemodynamic parameters and oxygenation in ARDS patients, due to the limited number of randomized clinical trials and the lack of studies investigating mortality, the use of iEPO cannot be recommended as standard of care in ARDS. iEPO should be reserved for those refractory to traditional therapies.

    FES (fat embolism syndrome) is a clinical problem, and, although ARDS (acute respiratory distress syndrome) has been considered as a serious complication of FES, the pathogenesis of ARDS associated with FES remains unclear. In the present study, we investigated the clinical manifestations, and biochemical and pathophysiological changes, in subjects associated with FES and ARDS, to elucidate the possible mechanisms involved in this disorder. A total of eight patients with FES were studied, and arterial blood pH, PaO(2) (arterial partial pressure of O(2)), PaCO(2) (arterial partial pressure of CO(2)), biochemical and pathophysiological data were obtained. These subjects suffered from crash injuries and developed FES associated with ARDS, and each died within 2 h after admission. In the subjects, chest radiography revealed that the lungs were clear on admission, and pulmonary infiltration was observed within 2 h of admission. Arterial blood pH and PaO(2) declined, whereas PaCO(2) increased. Plasma PLA(2) (phospholipase A(2)), nitrate/nitrite, methylguanidine, TNF-alpha (tumour necrosis factor-alpha), IL-1beta (interleukin-1beta) and IL-10 (interleukin-10) were significantly elevated. Pathological examinations revealed alveolar oedema and haemorrhage with multiple fat droplet depositions and fibrin thrombi. Fat droplets were also found in the arterioles and/or capillaries in the lung, kidney and brain. Immunohistochemical staining identified iNOS (inducible nitric oxide synthase) in alveolar macrophages. In conclusion, our clinical analysis suggests that PLA(2), NO, free radicals and pro-inflammatory cytokines are involved in the pathogenesis of ARDS associated with FES. The major source of NO is the alveolar macrophages.

    White-nose syndrome (WNS) has devastated bat populations in North America, with millions of bats dead. WNS is associated with physiological changes in hibernating bats, leading to increased arousals from hibernation and premature consumption of fat reserves. However, there is evidence of surviving populations of little brown myotis (Myotis lucifugus) close to where the fungus was first detected nearly ten years ago. We examined the hibernation patterns of a surviving population of little brown myotis and compared them to patterns in populations before the arrival of WNS and populations at the peak of WNS mortality. Despite infection with Pseudogymnoascus destructans, the causative fungal agent, the remnant population displayed less frequent arousals from torpor and lower torpid body temperatures than bats that died from WNS during the peak of mortality. The hibernation patterns of the remnant population resembled pre-WNS patterns with some modifications. These data show that remnant populations of little brown myotis do not experience the increase in periodic arousals from hibernation typified by bats dying from WNS, despite the presence of the fungal pathogen on their skin. These patterns may reflect the use of colder hibernacula microclimates by WNS survivors, and/or may reflect differences in how these bats respond to the disease.

    We reported on 2 atomic bomb survivors(a 60-year-old man and 63-year-old woman)suffering myelodysplastic syndrome(MDS) associated with 1p32 chromosomal abnormalities. They were exposed to atomic bomb radiation at distances of 1.2 and 1.1 km, respectively, and were given a diagnosis of MDS 44 and 46 years after the bombing, respectively. The male patient had refractory anemia(RA) and a bone marrow cell karyotype of 46, XY, del(1)(p22p32), t(8;11)(p11;p15). The female patient had RA with excess of blasts (RAEB) and a karyotype of 45, X, -X, t(1;11)(p32;q23), +del(1)(p32), inv(3) (p21q27), del(5)(q15), -6, -9, -19, +mar 1, +mar 2. Multi-separated nuclear megakaryocytes were observed in both patients. These findings suggested that they had been exposed to radiation near the atomic explosion despite the fact that their symptoms of MDS developed more than 40 years after the bombing. 1p32 is known to be the locus of the TAL1 gene. However, Southern blot analysis did not reveal rearrangement of the TAL1 gene in the male patient.

    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. 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. 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. 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. 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.

    The acute respiratory distress syndrome (ARDS) was re-defined by a panel of experts in Berlin in 2012. Although the Berlin criteria improved upon the validity and reliability of the definition, it did not make diagnosis of ARDS in resource limited settings possible. Mechanical ventilation, arterial blood gas measurements, and chest radiographs are not feasible in many regions of the world. In 2014, we proposed and applied the Kigali modification of the Berlin definition in a hospital in Rwanda. This review synthesizes literature from the last 18 months relevant to the Kigali modification. In the last 18 months, the need for a universally applicable ARDS definition was reinforced by advances in supportive care that can be implemented in resource poor settings. Research demonstrating the variable impact of positive end expiratory pressure on hypoxemia, the validity of using pulse oximetry rather than arterial blood gas to categorize hypoxemia, and the accuracy of lung ultrasound support the use of the Kigali modification of the Berlin definition. Studies directly comparing the Berlin definition to the Kigali modification are needed. Ongoing clinical research on ARDS needs to include low-income countries.

    A clinical trial of extracorporeal membrane oxygenation (ECMO) as an alternative ventilator tool is being performed as a new indication for ECMO. The purpose of this study was to evaluate the feasibility of awake ECMO to increase the success rate of weaning patients from ECMO and ventilator care during treatment of postoperative severe acute respiratory distress syndrome (ARDS). We retrospectively analyzed the clinical reports of 10 patients who underwent awake ECMO due to postoperative ARDS between August 2012 and May 2015. We analyzed patient history, the partial arterial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio, and patient outcome. Seven patients (70%) were weaned from ECMO without difficulty; one patient failed to maintain awake ECMO, was re-intubated after 2 days of awake ECMO, and was re-tried on awake ECMO after 4 days of ventilator care. We weaned that patient from ECMO 2 days later. We weaned a total of eight patients (80%) from awake ECMO. The ECMO duration of surviving patients was 9.13±2.2 days (range, 6-12 days), and mean ventilator use duration was 6.8±4.7 days (range, 2-16 days). Two cases failed awake ECMO and died due to disease aggravation. Awake ECMO was a useful weaning strategy after severe postoperative ARDS, as it avoids long-duration use of mechanical ventilation. Additionally, it is possible for patients to breathe spontaneously, which might prevents respiratory muscle dystrophy.

  4. Vascular pharmacology of acute lung injury and acute respiratory distress syndrome.

    PubMed

    2002-11-01

    Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) following sepsis, major trauma and surgery are leading causes of respiratory insufficiency, warranting artificial ventilation in the intensive care unit. It is caused by an inflammatory reaction in the lung upon exogenous or endogenous etiologies eliciting proinflammatory factors, and results in increased alveolocapillary permeability and protein-rich alveolar edema. The interstitial and alveolar inflammation and edema alter ventilation perfusion matching, gas exchange and mechanical properties of the lung. The current therapy of the condition is supportive, paying careful attention to fluid balance, relieving the increased work of breathing and improving gas exchange by mechanical ventilation, but in vitro, animal and some clinical research is done to evaluate the value of anti-inflammatory therapies on morbidity and outcome, including inflammatory cell-stabilizing corticosteroids, xanthine derivates, prostanoids and inhibitors, O(2) radical scavenging factors such as N-acetylcysteine, surfactant replacement, vasodilators including inhaled nitric oxide, vasoconstrictors such as almitrine, and others. None of these compounds has been proven to benefit survival in patients, however, even though carrying a physiologic benefit, except perhaps for steroids that may improve outcome in the later stage of ARDS. This partly relates to the difficulty to assess the lung injury at the bedside, to the multifactorial pathogenesis and the severity of comorbidity, adversely affecting survival.

    Death from traumatic shock has been associated with loss of blood externally or internally. However, many patients die after trauma, even though blood volume restoration is adequate. Death is often due to pulmonary failure (adult respiratory distress syndrome [ARDS]). Death and ARDS have been associated with disseminated intravascular coagulation (DIC) and microclots in the lungs. Dissolution of the microclots after trauma can be achieved by activation of endogenous plasmin. Nine pigs were anesthetized for 48 h. Trauma was administered by 60 standard blows to each thigh resulting in a bruise of muscle but no skin, bone, or major vessel injury. Nutrition and respiration were maintained at normal levels. All nine pigs died with severe lung pathology and low PaO2. Ten other traumatized pigs were treated with a plasminogen activator iv 4 h after trauma. Five of these were treated with tissue plasminogen activator (tPA) and five with urokinase. All treated pigs survived 48 h and maintained a normal PaO2. Autopsy showed minimal lung pathology.

    AIM: To implement high-throughput 16S rDNA sequencing to study microbial diversity in the fecal matter of rats with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). METHODS: Intratracheal instillation of lipopolysaccharide was used to induce ALI, and the pathological changes in the lungs and intestines were observed. D-lactate levels and diamine oxidase (DAO) activities were determined by enzymatic spectrophotometry. The fragments encompassing V4 16S rDNA hypervariable regions were PCR amplified from fecal samples, and the PCR products of V4 were sequenced by Illumina MiSeq. RESULTS: Increased D-lactate levels and DAO activities were observed in the model group (P < 0.01). Sequencing results revealed the presence of 3780 and 4142 species in the control and model groups, respectively. The percentage of shared species was 18.8419%. Compared with the control group, the model group had a higher diversity index and a lower number of species of Fusobacteria (at the phylum level), Helicobacter and Roseburia (at the genus level) (P < 0.01). Differences in species diversity, structure, distribution and composition were found between the control group and early ARDS group. CONCLUSION: The detection of specific bacteria allows early detection and diagnosis of ALI/ARDS. PMID:24914345

    Sepsis is a common condition that is associated with significant morbidity, mortality and health-care cost. Pulmonary and non-pulmonary sepsis are common causes of the acute respiratory distress syndrome (ARDS). The mortality from ARDS remains high despite protective lung ventilation, and currently there are no specific pharmacotherapies to treat sepsis or ARDS. Sepsis and ARDS are characterised by activation of the inflammatory cascade. Although there is much focus on the study of the dysregulated inflammation and its suppression, the associated activation of the haemostatic system has been largely ignored until recently. There has been extensive interest in the role that platelet activation can have in the inflammatory response through induction, aggregation and activation of leucocytes and other platelets. Aspirin can modulate multiple pathogenic mechanisms implicated in the development of multiple organ dysfunction in sepsis and ARDS. This review will discuss the role of the platelet, the mechanisms of action of aspirin in sepsis and ARDS, and aspirin as a potential therapy in treating sepsis and ARDS.

    This study was carried to evaluate the effect of early administration of dexamethasone on the incidence of bronchopulmonary dysplasia (BPD) and/or death in surfactant-treated preterm infants with respiratory distress syndrome (RDS). In a multicenter, double-blind, placebo-controlled trial, 109 preterm infants with RDS and birth weights between 700 and 1600 gm, who were treated with mechanical ventilation and surfactant, were randomly assigned before 36 hours of life to receive dexamethasone (n = 55) or placebo (n = 54) for 12 days. There were no differences in the incidence of BPD and/or death between groups. However, fewer patients in the dexamethasone group were oxygen-dependent at 36 weeks after conception (8% vs 33%, p < 0.05). The dexamethasone group had a lower incidence of necrotizing enterocolitis (0% vs 9%, p < 0.05). The incidence of arterial hypertension, hyperglycemia, and sepsis was not affected by the treatment. Basal and poststimulation serum cortisol levels did not differ between groups. The administration of dexamethasone early in the course of RDS does not decrease the incidence of BPD and/or death in preterm infants. However, dexamethasone may reduce oxygen dependency at 36 weeks after conception.

    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

    Acute respiratory distress syndrome (ARDS) is caused by infectious insults, such as pneumonia from various pathogens or related to other noninfectious events. Clinical and histopathologic characteristics are similar across severely affected patients, suggesting that a common mode of immune reaction may be involved in the immunopathogenesis of ARDS. There may be etiologic substances that have an affinity for respiratory cells and induce lung cell injury in cases of ARDS. These substances originate not only from pathogens, but also from injured host cells. At the molecular level, these substances have various sizes and biochemical characteristics, classifying them as protein substances and non-protein substances. Immune cells and immune proteins may recognize and act on these substances, including pathogenic proteins and peptides, depending upon the size and biochemical properties of the substances (this theory is known as the protein-homeostasis-system hypothesis). The severity or chronicity of ARDS depends on the amount of etiologic substances with corresponding immune reactions, the duration of the appearance of specific immune cells, or the repertoire of specific immune cells that control the substances. Therefore, treatment with early systemic immune modulators (corticosteroids and/or intravenous immunoglobulin) as soon as possible may reduce aberrant immune responses in the potential stage of ARDS.

    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.

    Elevated pulmonary arterial pressures appear to be a prominent feature of the acute respiratory distress syndrome (ARDS). Current clinical guidelines for the management of ARDS do not specifically address treatment of pulmonary hypertension or associated right ventricular dysfunction because the clinical significance of this entity remains unclear. Interpretation of elevated pulmonary arterial pressures, pulmonary vascular resistance, and transpulmonary gradient as well as signs of right ventricular dysfunction is confounded by the effects of positive pressure ventilation. There does not appear to be a consistent relationship between the diagnosis of pulmonary hypertension or right ventricular failure and mortality in patients with ARDS, but it is unclear if right ventricular failure contributes to the mortality risk per se or if the underlying cause of pulmonary hypertension, including intravascular micro and macro thrombosis, are simply markers for systemic dysregulation of coagulation and fibrinolysis that may lead to multiorgan failure in ARDS. While studies of pulmonary vasodilator therapies have not shown a mortality benefit in ARDS, such trials have targeted improved oxygenation rather than improved pulmonary hemodynamics so that the possible contribution of improved right ventricular function to better outcomes has not been directly tested in large trials. Future studies are needed to determine if treatment of pulmonary hypertension and associated right ventricular dysfunction will affect mortality in patients with ARDS.

    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.

    There is a need for biological markers of the acute respiratory distress syndrome (ARDS). Exhaled breath contains hundreds of metabolites in the gas phase, some of which reflect (patho)physiological processes. We aimed to determine the diagnostic accuracy of metabolites in exhaled breath as biomarkers of ARDS. Breath from ventilated intensive care unit patients (n=101) was analysed using gas chromatography and mass spectrometry during the first day of admission. ARDS was defined by the Berlin definition. Training and temporal validation cohorts were used. 23 patients in the training cohort (n=53) had ARDS. Three breath metabolites, octane, acetaldehyde and 3-methylheptane, could discriminate between ARDS and controls with an area under the receiver operating characteristic curve (AUC) of 0.80. Temporal external validation (19 ARDS cases in a cohort of 48) resulted in an AUC of 0.78. Discrimination was insensitive to adjustment for severity of disease, a direct or indirect cause of ARDS, comorbidities, or ventilator settings. Combination with the lung injury prediction score increased the AUC to 0.91 and improved net reclassification by 1.17. Exhaled breath analysis showed good diagnostic accuracy for ARDS, which was externally validated. These data suggest that exhaled breath analysis could be used for the diagnostic assessment of ARDS.

    To describe the clinical implications of an often neglected mechanism through which localized acute lung injury may be propagated and intensified. Experimental and clinical evidence from the medical literature relevant to the airway propagation hypothesis and its consequences. The diffuse injury that characterizes acute respiratory distress syndrome is often considered a process that begins synchronously throughout the lung, mediated by inhaled or blood-borne noxious agents. Relatively little attention has been paid to possibility that inflammatory lung injury may also begin focally and propagate sequentially via the airway network, proceeding mouth-ward from distal to proximal. Were this true, modifications of ventilatory pattern and position aimed at geographic containment of the injury process could help prevent its generalization and limit disease severity. The purposes of this communication are to call attention to this seldom considered mechanism for extending lung injury that might further justify implementation of low tidal volume/high positive end-expiratory pressure ventilatory strategies for lung protection and to suggest additional therapeutic measures implied by this broadened conceptual paradigm.

  16. Do airway secretions play an underappreciated role in acute respiratory distress syndrome?

    PubMed

    Graf, Jerónimo; Marini, John J

    2008-02-01

    We review the evidence that airway secretions may have an underappreciated role in acute respiratory distress syndrome, contributing to physiologic disarrangements, ventilator dependence and perhaps to injury generation. As common manipulations of ventilator settings, position and fluid status have the potential to influence these problems, explorations into the secretion dynamics of acute lung injury may be fertile ground for developing therapeutic advances. Principles that govern the interaction of airflow and airway fluids suggest that mobile fluids and secretions are pumped by well-selected ventilatory patterns toward the airway opening. Conversely, other selections may inhibit these fluids from clearance or encourage their translocation between lung regions. Recent laboratory work demonstrates that choices for tidal volume and positive end-expiratory pressure may localize or disperse proteinaceous lung edema or bacteria. Gravitational factors may interact with ventilatory pattern for benefit or harm. Capability of ventilation and positioning to mobilize secretions implies the potential for clearance or containment of inflammatory mediators and infection. Ventilatory and positional prescriptions could be designed to meet one of either conflicting targets. Additional experimental and clinical investigations are required before adopting these proposed therapeutic principles into practice.

    Advanced imaging techniques have provided invaluable insights in understanding of acute respiratory distress syndrome (ARDS) and the effect of therapeutic strategies, thanks to the possibility of gaining regional information and moving from simple 'anatomical' information to in-vivo functional imaging. Computed tomography (CT) led to the understanding of several ARDS mechanisms and interaction with mechanical ventilation. It is nowadays frequently part of routine diagnostic workup, often leading to treatment changes. Moreover, CT is a reference for novel techniques both in clinical and preclinical studies. Bedside transthoracic lung ultrasound allows semiquantitative regional analysis of lung aeration, identifies ARDS lung morphology and response to therapeutic maneuvers. Electrical impedance tomography is a radiation-free, functional, bedside, imaging modality which allows a real-time monitoring of regional ventilation. Finally, positron emission tomography (PET) is a functional imaging technique that allows to trace physiologic processes, by administration of a radioactive molecule. PET with FDG has been applied to patients with ARDS, thanks to its ability to track the inflammatory cells activity. Progresses in lung imaging are key to individualize therapy, diagnosis, and pathophysiological mechanism at play in any patient at any specified time, helping to move toward personalized medicine for ARDS.

    A 32-year-old female with epilepsy presented at our hospital with high-grade fever, seizures, and unconsciousness. She was initially treated for aspiration pneumonia with ampicillin/sulbactam. Despite antibiotic therapy, her chest X-ray findings dramatically worsened, showing extension to the bilateral lung field. Her PaO2/FiO2 ratio decreased to 70.6. Rapid progression of hypoxia, unconsciousness, and hyponatremia led to the suspicion of Legionella pneumonia; however, it was difficult to make a definitive diagnosis because she had denied using a whirlpool spa and the initial urinary Legionella antigen test results were negative. Therefore, we repeated the Legionella urinary antigen test, which was positive. On the basis of these results, sputum polymerase chain reaction findings, and the four-fold elevation of paired antibodies, the patient was diagnosed as having Legionella pneumonia accompanied by acute respiratory distress syndrome. We considered administering fluoroquinolone antibiotics, that are recommended for severe Legionella pneumonia, although quinolones have a potential risk for causing convulsions. In this case, we carefully administered ciprofloxacin. The patient recovered consciousness after treatment without any relapse of epileptic seizures. We also administered a corticosteroid for severe pneumonia with the expectation of clinical improvement and to avoid intubation. We emphasize the importance of aggressive workup and empirical therapy for patients with Legionella pneumonia with rapidly worsening symptoms and clinical features such as unconsciousness, epilepsy, and hyponatremia and in whom fluoroquinolone and corticosteroid therapy are effective despite the presence of epilepsy.

    Acute respiratory distress syndrome (ARDS) is a potential lethal disease. At present time no evidence based intervention reduces mortality. The pathophysiology of ARDS include intraalveolar fibrin deposition, hyperinflammation and reduced cellular host defense in the airspace. The normal lung activates protein C (PC) to activated protein C (APC), in contrast to the ARDS lung where the PC-APC axis is disrupted. The lungs have targets for inhaled APC as illustrated by a patient case with ARDS, unresponsive to conventional therapy. After inhalation of 190 μg/kg of APC (Drotrecogin alpha activated) three times a day for seven days, a clear reduction in infiltrates on chest X-ray and a 138% increase in oxygenation capacity as reflected by the PaO2/FiO2 ratio was brought about. The patient, however, died later after cardiac arrest after suspected recurrence of the T-cell lymphoma. No local or systemic adverse effects was found related to the iAPC, during, after or at the time of death. It is suggested based on existing studies and the presented case that inhaled APC is a new treatment option in patients with ARDS – a hypothesis which should be substantiated in a larger series of ARDS patients.

    Acute respiratory distress syndrome (ARDS) is an inflammatory condition of the lungs which can result in refractory and life-threatening hypoxaemic respiratory failure. The risk factors for the development of ARDS are many but include trauma, multiple blood transfusions, burns and major surgery, therefore this condition is not uncommon in the severely injured patient. When ARDS is severe, high-inspired oxygen concentrations are frequently required to minimise hypoxaemia. In these situations clinicians commonly utilise interventions termed 'hypoxaemic rescue therapies' in an attempt to improve oxygenation, as without these, conventional mechanical ventilation can be associated with high mortality. However, their lack of efficacy on mortality when used prophylactically in generalised ARDS cohorts has resulted in their use being confined to clinical trials and the subset of ARDS patients with refractory hypoxaemia. First line hypoxaemic rescue therapies include inhaled nitric oxide, prone positioning, alveolar recruitment manoeuvres and high frequency oscillatory ventilation, which have all been shown to be effective in improving oxygenation. In situations where these first line rescue therapies are inadequate extra-corporeal membrane oxygenation has emerged as a lifesaving second line rescue therapy. Rescue therapies in critically ill patients with traumatic injuries presents specific challenges and requires careful assessment of both the short and longer term benefits, therapeutic limitations, and specific adverse effects before their use.

  1. Determination of resonance frequency of the respiratory system in respiratory distress syndrome

    PubMed Central

    Lee, S; Alexander, J; Blowes, R; Ingram, D; Milner, A

    1999-01-01

    AIM—To measure tidal volume delivery produced by high frequency oscillation (HFO) at a range of frequencies including the resonance frequency.
METHODS—Eighteen infants with respiratory distress syndrome were recruited (median gestation 28.7 weeks). Each was ventilated at frequencies between 8 and 30 Hertz. Phase analysis was performed at various points of the respiratory cycle. HFO was provided by a variable speed piston device. Resonance frequency was determined from the phase relation between the cyclical movements of the piston and pressure changes at the airway opening. Tidal volume was measured using a jacket plethysmograph.
RESULTS—The results were most reproducible when analysis was performed at the end of inspiration (within 1 Hz in nine out of 10 cases). Comparison between tidal volume delivery at 10 Hz and resonance frequency was made in 10 subjects. Delivery was significantly higher at resonance than at 10 Hertz (mean percentage increase 92%, range 9-222%).
CONCLUSIONS—These preliminary findings suggest that there is improved volume delivery at resonance frequency.

    After a burn lesion, Acute Respiratory Distress Syndrome (ARDS) may occur via direct lung injury due to inhaled smoke and fumes or mediated by the inflammatory response associated with the burn or its infectious complications. The aim of the present study is to assess the epidemiologic profile of ARDS in adult burn patients admitted to intensive care in a burn unit at a university hospital. A prospective cohort study was performed from January to December 2012. Demographic and diagnostic data, prognostic scores, etiology and data on the extent and depth of burns were collected. Data related to risk factors for ARDS and death were also recorded. A total of 85 patients were included in the study. Patients were aged 41.7 (SD = 15.7) years old; 71.8% were male and the mean total body surface area burned was 28.3% (SD = 19.1%); 35.3% presented inhalation injuries. Invasive ventilatory support was required in 44 ICU inpatients (51.8%). ARDS was diagnosed in 38.6% of patients under invasive mechanical ventilation. In multivariate analysis, the presence of inhalation injuries was a risk factor for ARDS (OR = 9.75; CI 95% 2.79 - 33.95; P < 0.001). ARDS is a common complication in burn patients admitted to specialized intensive care units. Inhalation injuries were an independent risk factor for ARDS. Mortality rate observed in the study patients was high and associated with ARDS diagnosis.

    Enterobacter cloacae has emerged as an important nosocomial pathogen, but is rarely a cause of sacroiliitis. Herein, we present the first reported case of Enterobacter cloacae sacroiliitis associated with sepsis and acute respiratory distress syndrome (ARDS). A previously healthy 14-year-old boy presented with low-grade fever and pain in the left side of the hip that was aggravated by walking. Pelvic computed tomography (CT) showed normal findings, and the patient received supportive care for transient synovitis with no antibiotics. However, there was no clinical improvement. On the third day of hospitalization, magnetic resonance imaging of the hip revealed findings compatible with sacroiliitis, for which vancomycin and ceftriaxone were administered. The patient suddenly developed high fever with dyspnea. Chest radiography and CT findings and a PaO2/FiO2 ratio <200 mmHg were suggestive of ARDS; the patient subsequently received ventilatory support and low-dose methylprednisolone infusions. Within one week, defervescence occurred, and the patient was able to breathe on his own. Following the timely recognition of, and therapeutic challenge to, ARDS, and after 6 weeks of parenteral antimicrobial therapy, the patient was discharged in good health with no complications.

    Generalized pustular and/or erythrodermic psoriasis may have severe or even lethal complications. A peculiar noninfectious acute respiratory distress syndrome (so-called "sterile pneumonitis") has been described in generalized pustular psoriasis and/or erythrodermic psoriasis. We report a new case in a 14-year-old girl with a long history of pustular psoriasis and review the published work on this complication. The girl developed sterile pneumonitis during a disease flare-up, and high-dose corticosteroid therapy was quickly initiated. Within a few days, her clinical and radiological status was dramatically improved. The pathogenesis of aseptic pneumonitis is unknown, but various proinflammatory cytokines have been implicated, especially tumor necrosis factor-alpha, which could play a role in the recruitment of leukocytes to the lung. This complication has rarely been reported but should be more widely known as the differential diagnoses include congestive heart failure, acute lung infection related or unrelated to immunosuppressive therapy, and drug hypersensitivity reaction. Early recognition would avoid delays in the correct management of this potentially lethal complication, which requires high-dose systemic corticosteroid therapy.

    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.

    In some patients, acute respiratory distress syndrome (ARDS) leads to life-threatening refractory hypoxemia developing. Physicians may consider hypoxemic rescue therapies in an attempt to improve oxygenation in these patients while on conventional mechanical ventilation support. Use of inhaled nitric oxide (iNO) in ARDS is one of the most widely-studied pharmacological interventions over the past two decades. Its efficacy was examined in several randomized clinical trials and has undergone meta-analyses. Although iNO treatment was associated with improved oxygenation, researchers unfortunately never demonstrated a concomitant decrease in mortality or any improved outcome. Hence the current evidence suggests that iNO should not be routinely used in patients with ARDS however may be considered as adjunct therapy to tentatively improve oxygenation while other therapies are being considered in patients with severely hypoxemic ARDS.This review focuses on the therapeutic use of iNO in adult ARDS patients. We set out some recommendations for its use as rescue therapy against refractory hypoxemia.

    To compare the clinical efficacy of imported pulmonary surfactant (PS) pig lung phospholipids injection (pig PS) and domestic cattle lung surface-active agent (cattle PS) for the treatment of neonatal respiratory distress syndrome (NRDS). A total of 180 cases of grade IV NRDS receiving pig PS (n=90) or cattle PS treatment (n=90) were enrolled. The blood gas analysis and chest X-ray results and the incidence of complications after treatment, and hospitalization time and cost were compared between the two treatment groups. The efficiency rate in the pig PS group (97%) was higher than in the catle PS group (83%) (P<0.01). The cure rate in the pig PS group was also higher than in the cattle PS group (84% vs 66%; P<0.01). The incidence of pneumothorax in the pig PS group was lower than in the cattle PS group (3% vs 7%; P<0.05). The hospitalization time in the pig PS group was shorter than in the cattle PS group (21 ± 4 days vs 23 ± 4 days; P<0.05). There were no significant differences in the total hospitalization cost between the two groups. Pig PS seems to be superior to cattle PS in the treatment of grade IV NRDS.

    Aerosolization of exogenous surfactant remains a challenge. This study is aimed to evaluate the efficacy of atomized poractant alfa (Curosurf) administered with a novel atomizer in preterm lambs with respiratory distress syndrome. Twenty anaesthetized lambs, 127 ± 1 d gestational age, (mean ± SD) were instrumented before birth and randomized to receive either (i) positive pressure ventilation without surfactant (Control group), (ii) 200 mg/kg of bolus instilled surfactant (Bolus group) at 10 min of life or (iii) 200 mg/kg of atomized surfactant (Atomizer group) over 60 min from 10 min of life. All lambs were ventilated for 180 min with a standardized protocol. Lung mechanics, regional lung compliance (electrical impedance tomography), and carotid blood flow (CBF) were measured with arterial blood gas analysis. Dynamic compliance and oxygenation responses were similar in the Bolus and Atomizer groups, and both better than Control by 180 min (all P < 0.05; two-way ANOVA). Both surfactant groups demonstrated more homogeneous regional lung compliance throughout the study period. There were no differences in CBFConclusion:In a preterm lamb model, atomized surfactant resulted in similar gas exchange and mechanics as bolus administration. This study suggests evaluation of supraglottic atomization with this system when noninvasive support is warranted.

    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.

    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.

    Fibrin monomers inhibit surfactant function. 4G/5G insertion/deletion polymorphism plays an important role in the regulation of plasminogen activator inhibitor 1 (PAI-1) gene expression. To examine the genotype distribution of PAI-1 polymorphism in 60 infants with respiratory distress syndrome (RDS) and 53 controls, an allele-specific polymerase chain reaction (PCR) was used. The proportion of 4G/4G, 4G/5G, and 5G/5G genotypes did not differ statistically between the RDS and control groups (P > .05). Having PAI-1 4G/4G genotype polymorphism appears to increase the risk of RDS (odds ratio [OR] =1.5; 95% confidence interval [CI], 0.5-4.3), although it was not statistically significant. No relation was found between the PAI-1 4G/5G polymorphisms and RDS, but there was an increased risk associated with the 4G variant of the PAI-1 gene. We believe that our findings of increased 4G allele of the PAI-1 gene in infants with RDS would also help to clarify the pathogenesis of RDS.

    Acute respiratory distress syndrome (ARDS) is a major clinical problem with high morbidity and mortality. Diffuse alveolar damage (DAD) is considered the histological hallmark for the acute phase of ARDS. DAD is characterized by an acute phase with edema, hyaline membranes, and inflammation, followed by an organizing phase with alveolar septal fibrosis and type II pneumocyte hyperplasia. Given the difficulties in obtaining a biopsy in patients with ARDS, the presence of DAD is not required to make the diagnosis. However, biopsy and autopsy studies suggest that only one-half of patients who meet the clinical definition of ARDS also have DAD. The other half are found to have a group of heterogeneous disorders, including pneumonia. Importantly, the subgroup of patients with ARDS who also have DAD appears to have increased mortality. It is possible that the response of these patients to specific therapies targeting the molecular mechanisms of ARDS may differ from patients without DAD. Therefore, it may be important to develop noninvasive methods to identify DAD. A predictive model for DAD based on noninvasive measurements has been developed in an autopsy cohort but must be validated. It would be ideal to identify biomarkers or imaging techniques that help determine which patients with ARDS have DAD. We conclude that additional studies are needed to determine the effect of DAD on outcomes in ARDS, and whether noninvasive techniques to identify DAD should be developed with the goal of determining whether this population responds differently to specific therapies targeting the molecular mechanisms of ARDS.

    Many vasodilator drugs, including inhaled iloprost, are used to treat insufficient pulmonary vasodilatation, which is the main issue in pulmonary hypertension in newborns. The safety and efficacy of inhaled iloprost for the treatment of pulmonary hypertension were evaluated retrospectively in 15 preterm infants diagnosed with respiratory distress syndrome and pulmonary hypertension. The infants were unresponsive to surfactant and conventional mechanical ventilation and thus were treated with inhaled iloprost. Oxygenation parameters and hypoxemia improved rapidly after treatment. There was no decline in systemic blood pressure, no need for increased doses of vasopressor, and no side effects during treatment. One patient died of sepsis during treatment. In the treatment of severely sick premature babies with pulmonary hypertension, inhaled iloprost has high tolerability and a low incidence of systemic side effects. Based on the benefits of inhaled iloprost in preterm infants with pulmonary hypertension in this case series, further studies are required to evaluate its efficacy and safety in the preterm population.

    SUMMARY 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. Ecologic 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.

    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.

    The acute respiratory distress syndrome (ARDS) is an acute inflammatory process of the lung caused by a direct or indirect insult to the alveolar-capillary membrane. Currently, ARDS is diagnosed based on a combination of clinical and physiological variables. The lack of a specific biomarker for ARDS is arguably one of the most important obstacles to progress in developing novel treatments for ARDS. In this article, we will review the current understanding of some appealing biomarkers that have been measured in human blood, bronchoalveolar lavage fluid (BALF) or exhaled gas that could be used for identifying patients with ARDS, for enrolling ARDS patients into clinical trials, or for better monitoring of patient’s management. After a literature search, we identified several biomarkers that are associated with the highest sensitivity and specificity for the diagnosis or outcome prediction of ARDS: receptor for advanced glycation end-products (RAGE), angiopoietin-2 (Ang-2), surfactant protein D (SP-D), inteleukin-8, Fas and Fas ligand, procollagen peptide (PCP) I and III, octane, acetaldehyde, and 3-methylheptane. In general, these are cell-specific for epithelial or endothelial injury or involved in the inflammatory or infectious response. No biomarker or biomarkers have yet been confirmed for the diagnosis of ARDS or prediction of its prognosis. However, it is anticipated that in the near future, using biomarkers for defining ARDS, or for determining those patients who are more likely to benefit from a given therapy will have a major effect on clinical practice.

    An 87-year-old woman was admitted because of high fever, progressive dyspnea and abnormal shadows on chest roentgenogram. Laboratory investigation on admission demonstrated a normal white cell count with neutrophilia (4000/microl, 90.5% neutrophils), an erythrocyte sedimentation rate of 10 mm/h and C-reactive protein value of 9.0mg/dl. Roentgenogram and computed tomographic scan of the chest shows bilateral infiltration and diffuse ground glass opacity, indicating acute respiratory distress syndrome (ARDS), but disseminated nodules, indicating miliary tuberculosis, were not found. Blood gas analysis demonstrated severe hypoxemia (PaO2 43.2Torr with 6L/ min oxygen). Based on the diagnosis of acute pneumonia and ARDS, intravenous administration of sivelestat sodium hydrate (100 mg/day), and continuous infusion of hydrocortisone (200 mg/day) were started. PaO2/FiO2 ratio improved but X-ray findings showed no improvement and a blood test revealed pancytopenia. Bone marrow biopsy revealed necrotizing epithelioid granuloma and acid-fast bacilli. A polymerase chain reaction (PCR) test detected Mycobacterium tuberculosis. Mycobacterium tuberculosis was also detected in sputum and urine. Therefore, we diagnosed miliary tuberculosis and transferred the patient to an infectious disease hospital. Miliary tuberculosis complicated with ARDS is relatively rare and the prognosis is extremely poor. Miliary tuberculosis should be kept in mind as a cause of ARDS.

    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.

    Supine position may contribute to the loss of aerated lung volume in patients with acute respiratory distress syndrome (ARDS). We hypothesized that verticalization increases lung volume and improves gas exchange by reducing the pressure surrounding lung bases. Prospective observational physiological study in a medical ICU. In 16 patients with ARDS we measured arterial blood gases, pressure-volume curves of the respiratory system recorded from positive-end expiratory pressure (PEEP), and changes in lung volume in supine and vertical positions (trunk elevated at 45 degrees and legs down at 45 degrees ). Vertical positioning increased PaO(2) significantly from 94+/-33 to 142+/-49 mmHg, with an increase higher than 40% in 11 responders. The volume at 20 cmH(2)O measured on the PV curve from PEEP increased using the vertical position only in responders (233+/-146 vs. -8+/-9 1ml in nonresponders); this change was correlated to oxygenation change (rho=0.55). End-expiratory lung volume variation from supine to vertical and 1 h later back to supine, measured in 12 patients showed a significant increase during the 1-h upright period in responders (n=7) but not in nonresponders (n=5; 215+/-220 vs. 10+/-22 ml), suggesting a time-dependent recruitment. Vertical positioning is a simple technique that may improve oxygenation and lung recruitment in ARDS patients.

    Uric acid acts as both a pathogenic inflammatory mediator and an antioxidative agent. Several studies have shown that uric acid level correlates with the incidence, severity, and prognosis of pulmonary diseases. However, the association between uric acid level and acute respiratory distress syndrome (ARDS) has not been studied. This study was conducted to elucidate how serum uric acid level is related with clinical prognosis of ARDS. A retrospective cohort study with propensity score matching was conducted at a medical intensive care unit of a tertiary teaching hospital. The medical records of patients diagnosed with ARDS admitted from 2005 through 2011 were reviewed. Two hundred thirty-seven patients with ARDS met the inclusion criteria. Patients with a serum uric acid level <3.0 mg/dL were classified into the low uric acid group, and those with a level ≥3 mg/dL were classified into the normal to high uric acid group. We selected 40 patients in each group using propensity score matching. A higher percentage of patients in the low uric acid group experienced clinical improvement in ARDS. More patients died from sepsis in the normal to high uric acid group. Kaplan-Meier analysis showed that a low serum uric acid level was significantly associated with better survival rate. In patients with ARDS, a low serum uric acid level may be a prognostic marker of a low risk of in-hospital mortality.

    This study aimed to explore the effects of continuous blood purification (CBP) treatment in pigs affected with acute respiratory distress syndrome (ARDS). A total of 12 healthy male pigs, weighing 12±1.8 kg, were randomly and equally assigned to the control and experimental groups. The ARDS pig model was prepared by intravenous injections of endotoxin (20 µg/kg). The control group was given conventional supportive therapy, while the experimental group was given continuous veno-venous hemofiltration therapy. During the treatment process, the variations in dynamic lung compliance, oxygenation index, hemodynamics, and urine volume per hour at different times (Baseline, 0, 2, 4, and 6 h) were recorded. The levels of tumor necrosis factor (TNF-α), interleukin 6 (IL-6), and IL-10 in serum and bronchoalveolar lavage fluid (BALF) were measured using the enzyme-linked immunosorbent assay. The histomorphological changes of the lung, heart, and kidney were visualized using a light microscope. The nuclear factor κB p65 protein content of the heart, lung, and kidney tissues was also detected using western blot. The experimental group outperformed the control group in both respiratory and hemodynamic events. CBP treatment cleared TNF-α, IL-6, and IL-10 partially from serum and BALF. The pathological examination of the heart, lung, and kidney tissues revealed that the injury was less severe in the experimental group. CBP treatment can improve the organ functions of pigs affected with endotoxin-induced ARDS and protect these organs to some extent. PMID:28225865

    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

    This article compares the outcome and predictors of psychosocial distress of parents bereaved by young suicides, sudden infant death syndrome (SIDS), and child accidents. One objective is to explore whether suicide bereavement is more difficult for those left behind than other forms of bereavement. Data have been collected from 140 families, consisting of 232 parents, by the use of the Impact of Event Scale, the General Health Questionnaire, and the Inventory of Traumatic Grief. Qualitative aspects of bereavement are assessed by in-depth interviews with family members from 40 families. The results show that the similarities between the samples on outcome and predictors are more striking than the differences, which is explained by the common traumatic aspect of unexpected and violent deaths. One and a half years post-loss, 57-78% of the survivors scored above the cut-off levels for traumatic grief reactions. Although no significant differences are found between survivors of suicide and accidents, both groups evidence significantly greater subjective distress than the survivors of SIDS. Self-isolation is by far the best predictor of psychosocial distress in all three samples. Rather than focusing on the exceptional position of suicide survivors, it seems important to call attention to sudden and traumatic death in general as a factor to be associated with post-traumatic reactions and complicated mourning.

    To investigate the effect of continuous high-volume hemofiltration (HVHF) on extravascular lung water and respiratory mechanics in patients with acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS). Forty-one patients with ARDS and MODS were randomized into control group (20 patients) and HVHF treatment group (21 patients). The patients in HVHF treatment group undergoing mechanical ventilation were treated with HVHF (6 L/h) for 24 hours. The pulse indicator continuous cardiac output (PiCCO) catheter was inserted for monitoring cardiac output (CO), the extravascular lung water index (EVLWI) and intrathoracic blood volume index (ITBVI). Arterial partial pressure of oxygen (PaO(2)), arterial partial pressure of carbon dioxide (PaCO(2)), oxygenation index (PaO(2)/FiO(2)), peak airway pressure (Ppeak) and dynamic compliance (Cdyn) were measured. Concentrations of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in blood were detected by enzyme linked immunosorbent assay (ELISA). All indexes in control group did not show significant improvement before and after treatment (all P>0.05). There was significant lowering of concentrations of TNF-alpha and IL-6 in blood after HVHF at 24 hours, and also true in CO and EVLWI (all P<0.05). Ppeak and Cdyn were improved significantly, PaO(2)/FiO(2) increased markedly, and compared with that before HVHF and control group, significant differences were found in all the indexes (all P<0.05). HVHF shows significant beneficial effects on pulmonary function of patients with ARDS and MODS as a result of removal of cytokines, decrease in EVLWI and amelioration of disturbance in oxygen metabolism.

    To analyze the variation and significance of pulmonary circulation in patients with acute respiratory distress syndrome (ARDS) induced by lung contusion by means of Swan-Ganz catheter and the pulse index continuous cardiac output (PiCCO) monitoring. A prospective, randomized, non-blinded clinical trial was conducted. All patients admitted hospital from August 2009 to August 2011 met the inclusion criteria, were divided into the group with ARDS induced by lung contusion (contusion group, n = 18) and the group without lung contusion and ARDS (control group, n = 22). The measured parameters included pulmonary artery systolic pressure (PAS), pulmonary artery diastolic pressure (PAD), pulmonary artery wedge pressure (PAWP), pulmonary artery diastolic-pulmonary wedge pressure gradient (PAD-PAWP), and extravascular lung water index (ELWI) of each group at 0 hour after placing the catheter and at 12, 24, 36, 48, 60, 72 hours after contusion. The differences of all the parameters were compared within a group and among the different groups. In the survivors with ARDS induced by lung contusion, PAS, PAD and PAD-PAWP were significantly higher than those in the control group and then gradually declined. PAS and PAD returned to the level of control group at 60 hours after contusion, and the PAD-PAWP restored to the level of control group at 48 hours after contusion. For the patients in the control group, there were no significant differences in PAS and PAD from the 0 hour after placing catheter to 72 hours after contusion, but PAD-PAWP increased at 72 hours after contusion compared with at 48 hours. Compared with the control group, the ELWI in contusion group increased significantly, and peaked at 12 hours after contusion and then gradually declined, and restored to the level of control group at 60 hours after contusion. For the patients in the control group, ELWI were lower at 60 hours and 72 hours after contusion than at 48 hours. Compared with control group, PAWP in contusion

    There is growing recognition in psychology that wellness is more than the absence of disease and distress. Well-being has been defined in numerous ways. Two dominant models include Diener, Eunkook, Suh, Lucas and Smith's (1999) model of subjective well-being (SWB) and Ryff's (1989) model of psychological well-being (PWB). In contrast to the abundance of research investigating negative constructs and psychopathology in chronic fatigue syndrome (CFS), there has been a paucity of positive psychology studies. This study had two aims: to examine PWB and SWB and their relationship to symptoms in CFS and to compare PWB scores in a subgroup of the CFS sample to a matched control group. Chronic fatigue syndrome participants (n = 60) completed self-report scales of PWB, SWB, fatigue, anxiety and depression. PWB scores in a subgroup of the CFS sample (n = 42) were compared with those of a matched nonclinical control group (n = 42). Correlations between scales of symptoms and well-being were complex. Well-being dimensions were largely independent of physical components of fatigue but strongly related to psychological components of fatigue and psychological distress. Multiple regression indicated that five dimensions of well-being uniquely predicted symptomatology. Compared with the control group, the CFS group scored significantly lower on five of Ryff's six PWB dimensions, with particularly marked deficits in personal growth, environmental mastery and self-acceptance. This multidimensional assessment of well-being advances our understanding of CFS and offers new treatment targets. Future research must investigate whether interventions targeting theses well-being deficits can boost the efficacy of symptom-focused treatments. Copyright © 2016 John Wiley & Sons, Ltd. Previous psychological research into CFS has largely focused on the identification of negative constructs and CBT, a treatment that targets evidenced-based negative constructs, has demonstrated efficacy

    Severe respiratory distress syndrome (RDS) caused by pulmonary surfactant (PS) deficiency is described not only in preterm infants but also in term babies delivered via caesarean section, especially before the onset of labour (elective caesarean section). Once RDS of term neonates happened, mechanical ventilation is needed, and the infants were at high risk of developing further complications such as persistent pulmonary hypertension of neonates (PPHN), pulmonary air leak and cardiovascular instability, even fatal outcome cannot be avoided. The present study aimed to analyze the association between the elective caesarean section and respiratory distress syndrome (RDS) in term neonates, and to determine the related factors and outcomes of RDS cases in neonatal intensive care unit (NICU) and neonatology ward. A retrospective study was conducted at the NICU and the Neonatology Ward of A center (Children's Hospital of Zhejiang University) and the NICU of center B (Obstetrics and Gynecology Hospital of Zhejiang University) on 90 term infants who were diagnosed as RDS between June 2006 and June 2008. The general clinical data, mode of delivery, severity of the radiological sign, pulmonary surfactant (PS) application, the onset time and duration of mechanical ventilation, the ratio of PaO(2) to FIO(2) before mechanical ventilation, oxygenation index (OI), duration of oxygen supplementation, the length of hospital stay and complications including pulmonary air leaks (pneumothorax, pulmonary interstitial emphysema), PPHN, systemic hypotension and ventilator-associated pneumonia (VAP) were collected. The gestational age distribution was studied in RDS cases delivered by elective caesarean section, and the comparative analysis and non-conditional logistic regression analysis wer performed for clinical characteristics and risk factors between the RDS cases with or without complications. P < 0.05 was considered to be significant. There were 88 episodes of elective caesarean

    Recruitment manoeuvres involve transient elevations in airway pressure applied during mechanical ventilation to open ('recruit') collapsed lung units and increase the number of alveoli participating in tidal ventilation. Recruitment manoeuvres are often used to treat patients in intensive care who have acute respiratory distress syndrome (ARDS), but the effect of this treatment on clinical outcomes has not been well established. This systematic review is an update of a Cochrane review originally published in 2009. Our primary objective was to determine the effects of recruitment manoeuvres on mortality in adults with acute respiratory distress syndrome.Our secondary objective was to determine, in the same population, the effects of recruitment manoeuvres on oxygenation and adverse events (e.g. rate of barotrauma). For this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (OVID), Embase (OVID), the Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCO), Latin American and Caribbean Health Sciences (LILACS) and the International Standard Randomized Controlled Trial Number (ISRCTN) registry from inception to August 2016. We included randomized controlled trials (RCTs) of adults who were mechanically ventilated that compared recruitment manoeuvres versus standard care for patients given a diagnosis of ARDS. Two review authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Ten trials met the inclusion criteria for this review (n = 1658 participants). We found five trials to be at low risk of bias and five to be at moderate risk of bias. Six of the trials included recruitment manoeuvres as part of an open lung ventilation strategy that was different from control ventilation in aspects other than the recruitment manoeuvre (such as mode of ventilation, higher positive end-expiratory pressure (PEEP) titration and lower tidal volume or plateau

    To extend nursing knowledge of distress experienced by family caregivers of children with rare genetic disorders, by exploring the perspectives of caregivers of children with Russell-Silver Syndrome in Taiwan. Caring for a child with a rare genetic disorder often has profound effects on families, especially when diagnosis and treatment is complex or not yet well developed, such as that in Russell-Silver Syndrome (or Silver-Russell syndrome). This disorder causes dwarfism and developmental difficulties, requiring long-term care planning. Previous research has focused mostly on medical care, but little is known about families' perspectives of caring difficulties, the help they need and nursing care required. An exploratory qualitative approach was used to inform this study. Family caregivers, whose children were undergoing medical care in a leading Taiwan medical centre, were invited to participate in face-to-face, in-depth interviews. Data were analysed by content analysis. Fifteen caregivers including 11 mothers, two fathers and two grandmothers participated. Five major themes and 13 sub-themes of care-giving distress were identified: endless psychological worries; the lengthy process to confirm a medical diagnosis; adjustment efforts in modifying family roles; dilemmas in deciding between Western or Chinese traditional medicine; and negative responses to society's concerns. Their primary sources of support were spouses, parents and health professionals, accordingly. Complex physio-psycho-social and decision-making distress in caring for children with a rare genetic disorder were systematically revealed from the perspectives of ethnic-Chinese family caregivers. Long-term care plans for children with a rare genetic disorder such as Russell-Silver Syndrome need to focus on positive dynamic family interactions, life-stage development and family caregiver support. Research on care-giving in rare genetic disorders is also warranted across cultures and countries to

    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. In this study, we report that expansion of Ag-specific αβTh17 cells contributes to ARDS by local secretion of IL-17A, which in turn directly increases alveolar epithelial permeability. Mice with a highly restrictive defect in Ag-specific αβTh17 cells were protected from experimental ARDS induced by a single dose of endotracheal LPS. Loss of IL-17 receptor C or Ab 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 TCR. Our findings could be relevant to ARDS in humans, because we found significant elevation of IL-17A in bronchoalveolar lavage fluid from patients with ARDS, and rIL-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.

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

    ABSTRACT Pulmonary exposure to the plant toxin ricin leads to respiratory insufficiency and death. To date, in-depth study of acute respiratory distress syndrome (ARDS) following pulmonary exposure to toxins is hampered by the lack of an appropriate animal model. To this end, we established the pig as a large animal model for the comprehensive study of the multifarious clinical manifestations of pulmonary ricinosis. Here, we report for the first time, the monitoring of barometric whole body plethysmography for pulmonary function tests in non-anesthetized ricin-treated pigs. Up to 30 h post-exposure, as a result of progressing hypoxemia and to prevent carbon dioxide retention, animals exhibited a compensatory response of elevation in minute volume, attributed mainly to a large elevation in respiratory rate with minimal response in tidal volume. This response was followed by decompensation, manifested by a decrease in minute volume and severe hypoxemia, refractory to oxygen treatment. Radiological evaluation revealed evidence of early diffuse bilateral pulmonary infiltrates while hemodynamic parameters remained unchanged, excluding cardiac failure as an explanation for respiratory insufficiency. Ricin-intoxicated pigs suffered from increased lung permeability accompanied by cytokine storming. Histological studies revealed lung tissue insults that accumulated over time and led to diffuse alveolar damage. Charting the decline in PaO2/FiO2 ratio in a mechanically ventilated pig confirmed that ricin-induced respiratory damage complies with the accepted diagnostic criteria for ARDS. The establishment of this animal model of pulmonary ricinosis should help in the pursuit of efficient medical countermeasures specifically tailored to deal with the respiratory deficiencies stemming from ricin-induced ARDS.

    To determine the relationship between airspace cytokines and cellular inflammatory responses in patients with the acute respiratory distress syndrome (ARDS), we performed bronchoalveolar lavage (BAL) in 82 prospectively identified, mechanically ventilated patients on Days 3, 7, 14, and/or 21 after the onset of ARDS. We studied the relationships between bronchoalveolar lavage fluid (BALF) cell populations and the concentrations of two potent neutrophil (PMN) chemoattractants, interleukin-8 (IL-8) and epithelial cell-derived neutrophil activator-78 (ENA-78); two potent monocyte chemoattractants, monocyte chemotactic peptide-1 (MCP-1) and macrophage inflammatory peptide-1 alpha (MIP-1 alpha); and the early response cytokine interleukin-1 beta (IL-1 beta) and its naturally occurring antagonist, IL-1 receptor antagonist protein (IRAP). We found that all of these cytokines were significantly increased regardless of the duration of ARDS. IL-8 and ENA-78 were the cytokines most strongly and consistently correlated with PMN concentrations in the lung fluids of patients with ARDS, and the correlations were independent of the other cytokines or coexisting lung infection. None of the cytokines tested correlated with macrophage concentrations. MCP-1 was directly correlated with lung injury score on Days 7, 14, and 21. Although neither IL-8 nor ENA-78 was associated with outcome, levels of IL-1 beta measured on Day 7 were associated with an increased risk of death (odds ratio [OR] = 2.8; 95% confidence interval [CI] = 1.1 to 7.4). These data demonstrate potential molecular mechanisms of the persistent inflammatory process in the lungs of patients with ARDS.

    The role of nitric oxide synthase (NOS) in the pathophysiology of acute respiratory distress syndrome (ARDS) is not well understood. Inducible NOS is upregulated during physiologic stress; however, if NOS substrate is insufficient then NOS can uncouple and switch from NO generation to production of damaging peroxynitrites. We hypothesized that NOS substrate levels are low in patients with severe sepsis and that low levels of the NOS substrate citrulline would be associated with end organ damage including ARDS in severe sepsis. Plasma citrulline, arginine and ornithine levels and nitrate/nitrite were measured at baseline in 135 patients with severe sepsis. ARDS was diagnosed by consensus definitions. Plasma citrulline levels were below normal in all patients (median 9.2 uM, IQR 5.2 - 14.4) and were significantly lower in ARDS compared to the no ARDS group (6.0 (3.3 - 10.4) vs. 10.1 (6.2 - 16.6), P = 0.002). The rate of ARDS was 50% in the lowest citrulline quartile compared to 15% in the highest citrulline quartile (P = 0.002). In multivariable analyses, citrulline levels were associated with ARDS even after adjustment for covariates including severity of illness. In severe sepsis, levels of the NOS substrate citrulline are low and are associated with ARDS. Low NOS substrate levels have been shown in other disease states to lead to NOS uncoupling and oxidative injury suggesting a potential mechanism for the association between low citrulline and ARDS. Further studies are needed to determine whether citrulline supplementation could prevent the development of ARDS in patients with severe sepsis and to determine its role in NOS coupling and function.

    The objective of this study was to analyze the association between candidate gene polymorphisms and susceptibility to acute respiratory distress syndrome (ARDS) in patients with severe sepsis. Patients older than 18 years admitted to the intensive care unit (ICU) with the diagnosis of severe sepsis were prospectively included. A blood sample was drawn on the first day of ICU admission, and DNA was extracted. We genotyped the insertion/deletion polymorphism of the angiotensin-converting enzyme (ACE) gene (polymerase chain reaction) and the following single-nucleotide polymorphisms (TaqMan SNP genotyping assay): tumor necrosis factor α -376 G/A, -308 G/A, and -238 G/A; interleukin 8 -251 T/A; pre-B cell colony-enhancing factor -1001 G/T; and vascular endothelial growth factor +405 C/G and +936 C/T. Polymorphisms were selected based on reports on their association with ARDS. Variables associated in univariate analysis (P < 0.1) with the diagnosis of ARDS were included in a multiple logistic regression analysis. We studied 149 patients, of whom 35 presented ARDS. Variables included in the maximal multivariate model were male sex, chronic alcoholism, use of ACE inhibitors or angiotensin-receptor blockers, Simplified Acute Physiology Score II score, serum glucose concentration at ICU admission, and the presence of the allele D of the ACE gene. After adjustment for those variables, the presence of the allele D of the ACE gene (odds ratio, 4.75; 95% confidence interval, 1.02-22.20; P = 0.048) was significantly associated with the diagnosis of ARDS. The presence of the allele D of the ACE gene is associated with ARDS in patients with severe sepsis.

    The rate of preterm births has remained unchanged for the recent years despite of the persistent attempts to diminish it. Preterm births are responsible for about 70% of neonatal morbidity and mortality. One of the main problems of preterm newborns is their lung immaturity. The aim of this study is to assess the effect of Ambroxol, given prenatally on the rate and severity of neonatal respiratory distress syndrome (NRDS) in preterm infants and its potential to replace the corticosteroid prophylaxis in cases where steroids are contraindicated or undesirable. The trial consisted of 33 pregnant women between 27 and 32 week of gestation. 17 of them represented our work group and were given Ambroxol syrup 15 mg/ml, per os 30 ml in three intakes, for 7 days. 16 were controls and were not given any kind of NRDS prophylaxis. severe NRDS was diagnosed in 2.5 times more cases in the control group compared to the work group. All infants in the control group had clinical signs of NRDS, while 23.5% of the infants in the work group were asymptomatic. Bronchopulmonary dysplasia was diagnosed in 25% of the infants in the control group, compared to none diagnosed in the work group. Newborns with no antenatal NRDS prophylaxis had to be kept in intensive care units for an average period of time twice longer than the newborns to mothers who had received Ambroxol. Antenatal Ambroxol administration diminishes the rate of NRDS, decreases the duration, scope and price of the intensive care, lessens the duration of assisted ventilation and oxygen needs and hence improves the long-term outcome. Ambroxol and steroids have cumulative effect on fetal lung maturation and therefore should both be a part of the preterm delivery therapeutic scheme.

    Mechanical ventilation is the type of organ support most widely provided in the intensive care unit. However, this form of support does not constitute a cure for acute respiratory distress syndrome (ARDS), as it mainly works by buying time for the lungs to heal while contributing to the maintenance of vital gas exchange. Moreover, it can further damage the lung, leading to the development of a particular form of lung injury named ventilator-induced lung injury (VILI). Experimental evidence accumulated over the last 30 years highlighted the factors associated with an injurious form of mechanical ventilation. The present paper illustrates the physiological effects of delivering a tidal volume to the lungs of patients with ARDS, and suggests an approach to tidal volume selection. The relationship between tidal volume and the development of VILI, the so called volotrauma, will be reviewed. The still actual suggestion of a lung-protective ventilatory strategy based on the use of low tidal volumes scaled to the predicted body weight (PBW) will be presented, together with newer strategies such as the use of airway driving pressure as a surrogate for the amount of ventilatable lung tissue or the concept of strain, i.e., the ratio between the tidal volume delivered relative to the resting condition, that is the functional residual capacity (FRC). An ultra-low tidal volume strategy with the use of extracorporeal carbon dioxide removal (ECCO2R) will be presented and discussed. Eventually, the role of other ventilator-related parameters in the generation of VILI will be considered (namely, plateau pressure, airway driving pressure, respiratory rate (RR), inspiratory flow), and the promising unifying framework of mechanical power will be presented.

    The present study examines the histological features of the lungs of neonates who died of respiratory distress syndrome or related complications after surfactant therapy. Our aim was to determine whether these lungs showed any unusual histological findings. Complete autopsies were performed 6-12 h after death in 10 surfactant-treated preterm infants and in 30 infants who died before surfactant therapy was available. Representative paraffin sections of all pulmonary lobes, stained with haematoxylin and eosin, were examined microscopically. A few selected slides were also stained with periodic acid-Schiff, Vierhoff-van Gieson, and Mallory trichrome. Hyaline membrane disease and bronchopulmonary dysplasia were present in each group, although there was an increased incidence of intra-alveolar haemorrhage in surfactant-treated babies (in 8 of 10 surfactant-treated as compared with 7 of 30 untreated babies). Amongst those treated with surfactant, we observed the persistence of acute alveolar damage with unresolved hyaline membrane disease in 5 infants who died at the ages of 5, 6, 10, 12, and 13 days, respectively, and histological evidence of pneumocyte type 2 hyperplasia and dysplasia in 2 infants who died at 22 and 41 days of age, respectively. These observations reveal that surfactant-treated infants who fail to respond to therapy have continuing alveolar injury and an increased incidence of intra-alveolar haemorrhage. Since oxygen radicals can induce pneumocyte damage and necrosis and since free radicals provoke alveolar haemorrhage in animal models, we propose that the lesions we observed may stem from a lack, in some preterm babies, of specific mechanisms that detoxify oxygen radicals.

    The present study was aimed to investigate the role of necroptosis in the pathogenesis of acute respiratory distress syndrome (ARDS). The rat model of ARDS was induced by intravenous injection of oleic acid (OA), and observed for 4 h. The lung injury was evaluated by arterial blood gas, lung wet-dry weight ratio (W/D) and histological analyses. Simultaneously, bronchoalveolar lavage fluid (BALF) was collected for total and differential cell analysis and total protein determination. Tumor necrosis factor alpha (TNF-α) level in BALF was determined with a rat TNF-α ELISA kit. Expressions of receptor interacting protein kinase 1 (RIPK1), RIPK3 and mixed lineage kinase domain-like protein (MLKL) in lung tissue were determined by Western blot and immunohistochemical staining. The interaction between RIPK1 and RIPK3 was explored by immunoprecipitation. The results showed that, compared with those in control group, total white blood cells count (WBC), polymorphonuclear percentage (PMN%), total protein concentration, TNF-α level in BALF, W/D, and the alveolar-arterial oxygen tension difference (P(A-a)O2) in OA group were significantly increased at 4 h after OA injection. Western blot and immunostaining further showed remarkably increased expressions of RIPK1, RIPK3 and MLKL in lung tissue from OA group. Additionally, immunoprecipitation results indicated an enforced interaction between RIPK1 and RIPK3 in OA group. Collectively, the TNF-α level in BALF and the RIPK1-RIPK3-MLKL signaling pathway in lung tissue were found to be upregulated and activated with the process of ARDS. These findings implicate that RIPK1/RIPK3-mediated necroptosis plays a possible role in the pathogenesis of ARDS, which may provide a new idea to develop novel drugs for the therapy of ARDS.

    Background: The role of Mycoplasma pneumoniae (Mp) in the initiation and persistence of asthma remains elusive. Mp community-acquired respiratory distress syndrome toxin (CARDS Tx) is a unique virulence factor that induces an intense lymphocytic response and exacerbates asthma in animal models. We sought to determine the incidence of Mp infection and the presence of CARDS Tx in subjects with refractory asthma (RA). Methods: We conducted a prospective observational study in 64 subjects with RA. Respiratory secretions (sputum, nasal lavage, and throat swab) and blood were analyzed for the presence of CARDS Tx and P1 adhesin (P1) DNA by polymerase chain reaction (PCR), and CARDS Tx by antigen capture. Serum IgM and IgG antibodies to CARDS Tx were determined by enzyme-linked immunosorbent assay (ELISA). Results: Thirty-three of 64 subjects (52%) tested positive for Mp: 29 of 33 by CARDS Tx vs 10 of 33 by P1 assays. Ten subjects followed longitudinally for up to 633 days tested persistently positive for Mp. There were no significant differences in Mp-specific IgG responses between Mp-positive and Mp-negative groups. Eight of 10 subjects who tested persistently positive failed to mount a substantial IgG response to CARDS Tx, and up to 8 weeks of clarithromycin failed to eradicate Mp in five subjects. Conclusions: Subjects with RA may be chronically infected with Mp. PCR for CARDS Tx appears to be the most sensitive method of identifying Mp infection. Despite the persistence of Mp in subjects with RA, some subjects failed to mount an IgG response, and macrolide therapy was insufficient to eradicate Mp. PMID:21622549

    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

    Blastomyces dermatitidis is a dimorphic fungus endemic to North America capable of causing fatal respiratory failure. Acute respiratory distress syndrome (ARDS) complicates up to 10% of pulmonary blastomycosis in hospitalized patients and carries a mortality of 50-90%. This report describes the clinical course of four consecutive patients with blastomycosis-related ARDS treated with venovenous extracorporeal membrane oxygenation (ECMO) during 2009-2014. Four adults were referred from northwestern Ontario, Canada with progressive respiratory illnesses. All patients developed diffuse bilateral opacities on chest radiography and required mechanical ventilation within 6-72 hr. Patients satisfied Berlin criteria for severe ARDS with trough PaO2/F i O2 ratios of 44-61 on positive end-expiratory pressure of 12-24 cm H2O. Wet mount microscopy from respiratory samples showed broad-based yeast consistent with B.dermatitidis. Despite lung protective ventilation strategies with maximal F i O2 (patients A-D), neuromuscular blockade (patients A-D), inhaled nitric oxide (patients A and D), and prone positioning (patient D), progressive hypoxemia resulted in initiation of venovenous ECMO by hours 24-90 of mechanical ventilation with subsequent de-escalation of ventilatory support. In all four cases, ECMO decannulation was performed (7-23 days), mechanical ventilation was withdrawn (18-52 days), and the patients survived to hospital discharge (31-87 days). This report describes the successful application of ECMO as rescue therapy in aid of four patients with refractory blastomycosis-associated ARDS. In addition to early appropriate antimicrobial therapy, transfer to an institution experienced with ECMO should be considered when caring for patients from endemic areas with rapidly progressive respiratory failure.

    Abstract Acute respiratory distress syndrome (ARDS) is an uncommon, highly fatal, and poorly understood manifestation of blastomycosis. Optimal management remains unknown, including the roles of adjunctive corticosteroids and extracorporeal membrane oxygenation (ECMO). We conducted a retrospective chart review of patients with ARDS caused by blastomycosis, managed in intensive care units in Manitoba, Canada, from 1992 to 2014. ARDS was defined using the Berlin definition. Corticosteroid therapy was defined as ≥150 mg cortisol equivalent in 24 hours. Logistic regression was used to identify determinants of a fatal outcome, and bootstrap resampling was used to assess sample size requirements. Forty-three patients with ARDS caused by blastomycosis were identified. ARDS was mild, moderate, and severe in 2 (5%), 12 (28%), and 29 (67%) patients, respectively. Management included amphotericin B (n = 42, 98%), vasopressors (n = 36, 84%), corticosteroids (n = 22, 51%), renal replacement (n = 13, 30%), and ECMO (n = 4, 11%). Seventeen patients (40%) died. All patients treated with ECMO survived (P = 0.14). Corticosteroids were not associated with survival benefit in univariate (P = 0.43) or multivariate analyses (odds ratio 0.52, 95% confidence interval 0.11–2.34). Bootstrap studies indicated that almost 500 patients would be needed to confirm a significant reduction in mortality from corticosteroids (type I error = 0.05, power = 80%). Blastomycosis is an uncommon, albeit important, cause of ARDS in this geographic area. Given the rarity of disease and the large cohort needed to demonstrate mortality benefit, the role of adjunctive therapies, including corticosteroids and ECMO, may remain unconfirmed, and clinical judgment should guide management decisions.

    BACKGROUND Adherence to rigorous research protocols for identifying acute respiratory distress syndrome (ARDS) after trauma is variable. To examine how misclassification of ARDS may bias observational studies in trauma populations, we evaluated the agreement of two methods for adjudicating ARDS after trauma: the gold standard, direct review of chest radiographs and review of dictated radiology reports, a commonly used alternative. METHODS This nested cohort study included 123 mechanically ventilated patients between 2005–2008, with at least one PaO2:FiO2 <300 within the first 8 days of admission. Two blinded p
