Management of Alveolar Proteinosis by Bronchopulmonary lavage under Extra Corporeal Membrane Oxygenation (ECMO)

The gold standard of treating Pulmonary Alveolar Proteinosis (PAP) is bronchopulmonary lavage (BPL). We describe a rare case of BPD for PAP, who underwent extracorporeal membrane oxygenation (ECMO) due to hypoventilation in the setting of one-lung ventilation. First, the clinical course of the patient is presented; furthermore, the biomolecular basis of PAP and new treatment approaches is discussed. &nbsp

Thiamine can decrease Lactate and Creatinine level after Coronary Artery Bypass Surgery in Patients with Mild Systolic Dysfunction

Introduction: During cardiopulmonary bypass, oxidative stress happens in the patient's cells due to blood contact with various levels of synthetic materials. It can activate inflammatory process and release factors such as IL-6, CRP, and Neutrophils witch may hurt different organs. In recent years, many efforts have been made to prevent this type of damage, however, no single treatment has been proposed to reduce this risk. Antioxidant substances such as Thiamine is important in cell defense against free oxygen radicals. Regarding this issue, in this study, the effect of thiamine on lactate levels in patients undergoing coronary artery bypass graft surgery has been investigated.Materials and methods: In this study, 140 patients from 25 to 65 years old with mild systolic dysfunction (EF = 45-55%) who were candidates for elective CABG surgery in two groups: control and purpose (patients receiving Thiamine) were examined. All of these patients were anesthetized in an identical manner, and were subjected to a heart-lung pump. Serum lactate levels were measured before, during and 6, 12, 18, and 24 hours after surgery. All data collected in a questionnaire were recorded and evaluated using spss statistical software.Results: Study groups showed no significant differences regarding demographics and underlying diseases. Serum lactate was significantly lower in thiamine group during the first 24 hours after surgery (except before operation and 2 hours later) (p <0.05).Creatinine level in two groups before surgery was not significantly different ,However, it was significantly lower in case group 24 hours after surgery(1.54±0.14 vs. 1.24±0.19; p: 0.001).Also, dose of Inotropes in  patients who received thiamine, was significantly lower than the control group (p= 0.001). Extubation was longer in control group (15.4±4.9 vs. 13.15±4.1; p=0.003) while ICU stay was not different.Conclusion: It seems that thiamine administration before cardiopulmonary bypass, in patient with decreased left ventricular function, can decrease serum lactate as tissue perfusion marker and also improve kidney function

Real-time RT-PCR Detection of HCN4 and ADAM8 genes in ventilator-associated pneumonia patients Hospitalized in intensive care unit

IntroductionVentilator-associated pneumonia (VAP)  is One of the most serious and  prevalence of  complication  among patients in the intensive care unit nosocomial infections, which are often recognized after detecting symptoms. To date, there has been no proper clinical and diagnostic marker for early detection of this disease. In this study, two HCN4 and ADAM8 genes in patients with VAP were assessed to be used as a biomarker to recognize and distinguish the disease.   MethodologyThis study was done in Masih Daneshvari Hospital affiliated to Shahid Beheshti University of Medical Sciences,Tehran,Iran since 2015-2016 and was case /control study . current study was administered by using peripheral blood samples, including 30 patients with VAP and 30 Healthy person. First, the peripheral blood samples were taken and then RNA was extracted and then synthesis CDNA. Finally, the evaluation of genes was performed by Realtime PCR method.   FindingsIn peripheral blood samples, patients individuals , 10 out of 30 cases had positive HCN4 markers. Among the healthy individuals, 6 out of 30 cases had positive HCN4  biomarkers. Moreover, in ADAM8 marker patients individuals, 13 out of 30 cases had positive ADAM8 marker and 8 out of 30 healthy individuals had positive ADAM8 biomarkers.ConclusionGenes HCN4 and ADAM8  assessment with Real Time-PCR  in this study can be used as promising markers in early detection of VAP disease. More extensive studies on larger sample sizes may yield higher sensitivity for these molecular markers

An eleven-year retrospective cross-sectional study on pulmonary alveolar proteinosis

Introduction: Pulmonary alveolar proteinosis (PAP) is a rare disease in the field of pulmonary medicine. The efficacy of whole-lunglavage (WLL) as the treatment of PAP had never been evaluated in the Iranian population. Therefore, there is a real need to investigatethe characteristics of PAP and also to evaluate the efficacy of WLL in this rare disease. The study aimed to investigatedemographic features, clinical presentation and treatment outcomes of the disease in Iranian PAP patients. Material and methods: Data of 45 patients with definite diagnosis of PAP, who had regular follow-ups from March 2004 to March2015 at an Iranian referral respiratory hospital, were collected. Whole-lung lavages (WLL) efficacy was assessed by comparingspirometric, arterial blood gas parameters and six-minute walk test (6MWT) results before and after all lavages. Results: Mean age at diagnosis of disease was 30.33 ± 14.56 years. Four patients (8.8%) reported non-massive hemoptysis and threesubjects (6.6%) had concomitant pulmonary tuberculosis. In 71.1% of cases, transbronchial lung biopsy and bronchoalveolar lavage weresufficient for diagnosis. Spirometric results and arterial blood gas parameters and 6MWD improved significantly after all the lavages. Fourpatients (8.8%) died because of respiratory failure. The only variable capable of predicting treatment failure was the history of hemoptysis. Conclusion: The study revealed sufficiency of WLL as the PAP patients’ treatment. Also hemoptysis was found to be the independentfactor that can predict treatment failure

Histopathologic Findings of Olfactory Mucosa in COVID-19 Patients

Background: Olfactory manifestations are common findings during the course of COVID-19, while exact physiopathology is not known Aim: We review histological changes of the nasal olfactory mucosa in COVID-19 non-survivors who died in the ICU. Methods: Sampling was done within 1 hour of death under direct vision. Specimens were taken medial to the middle turbinate in the cribriform area and embedded in paraffin blocks and stained by haematoxylin and eosin. Results: The most frequent histologic finding was the infiltration of inflammatory cells mostly comprised of lymphocytes. Inflammatory infiltration of mucosa was seen in all 11 patients with ulceration in 9 cases and neuritis in 3 cases.  Conclusion: Inflammatory infiltration of olfactory mucosa may be associated with smell manifestations. Further histological studies will clarify the role of the nasal mucosa in the physiopathology of COVID-19 especially olfactory involvement

Jedenastoletnie, retrospektywne badanie przekrojowe dotyczące proteinozy pęcherzyków płucnych

WSTĘP: Proteinoza pęcherzyków płucnych (PAP, pulmonary alveolar proteinosis) to rzadka choroba płuc. W populacji irańskiej nie analizowano nigdy skuteczności płukania całego płuca (WLL, whole-lung lavage) jako leczenia PAP. Z tego powodu oceniono charakterystykę PAP, a także skuteczność WLL w tej rzadkiej chorobie. Niniejsze badanie miało na celu analizę cech demograficznych, obrazu klinicznego i wyników leczenie tej choroby u irańskich pacjentów z PAP. MATERIAŁ I METODY: Zgromadzono dane 45 pacjentów z pewnym rozpoznaniem PAP, regularnie obserwowanych od marca 2004 do marca 2015 roku w irańskim szpitalu referencyjnym. Skuteczność WLL oceniano, porównując parametry spirometryczne, gazometrii krwi tętniczej oraz testu 6-minutowego marszu (6MWT, 6 minute walk test) przed i po wykonaniu wszystkich zabiegów płukania płuca. WYNIKI: Średni wiek w momencie rozpoznania choroby wynosił 30,33 ± 14,56 roku. U czterech pacjentów (8,8%) występowało niemasywne krwioplucie, u trzech (6,6%) współistniała gruźlica płuc. Biopsja przezoskrzelowa płuca i płukanie oskrzelowo- -pęcherzykowe w 71,1% przypadków były wystarczającymi badaniami do postawienia rozpoznania. Wyniki spirometryczne, parametry gazometrii krwi tętniczej i 6MWD poprawiły się znamiennie po przeprowadzeniu wszystkich zabiegów płukania płuca. Czterech pacjentów (8,8%) zmarło z powodu niewydolności oddechowej. Jedyną zmienną mogącą przewidzieć niepowodzenie leczenia było występowanie krwioplucia w wywiadzie chorobowym. WNIOSKI: W badaniu wykazano, że WLL jest leczeniem skutecznym u pacjentów z PAP. Krwioplucie było niezależnym czynnikiem predykcyjnym niepowodzenia leczenia.WSTĘP: Proteinoza pęcherzyków płucnych (PAP, pulmonary alveolar proteinosis) to rzadka choroba płuc.

Cardiac Rehabilitation Using The Family-Centered Empowerment Model Versus Home-Based Cardiac Rehabilitation In Patients With Myocardial Infarction: A Randomised Controlled Trial

Objective To determine if a hybrid cardiac rehabilitation (CR) programme using the Family-Centered Empowerment Model (FCEM) as compared with standard CR will improve patient quality of life, perceived stress and state anxiety of patients with myocardial infarction (MI). Methods We conducted a randomised controlled trial in which patients received either standard home CR or CR using the FCEM strategy. Patient empowerment was measured with FCEM questionnaires preintervention and postintervention for a total of 9 assessments. Quality of life, perceived stress, and state and trait anxiety were assessed using the 36-Item Short Form Health Survey (SF-36), the 14-item Perceived Stress, and the 20-item State and 20-item Trait Anxiety questionnaires, respectively. Results 70 patients were randomised. Baseline characteristics were similar. Ejection fraction was significantly higher in the intervention group at measurements 2 (p=0.01) and 3 (p=0.001). Exercise tolerance measured as walking distance was significantly improved in the intervention group throughout the study. The quality of life results in the FCEM group showed significant improvement both within the group over time (p\u3c0.0001) and when compared with control (p\u3c0.0001). Similarly, the perceived stress and state anxiety results showed significant improvement both within the FCEM group over time (p\u3c0.0001) and when compared with control (p\u3c0.0001). No significant difference was found either within or between groups for trait anxiety. Conclusions The family-centred empowerment model may be an effective hybrid cardiac rehabilitation method for improving the physical and mental health of patients post-MI; however, further study is needed to validate these findings.

Comparison of non-invasive to invasive oxygenation ratios for diagnosing acute respiratory distress syndrome following coronary artery bypass graft surgery: a prospective derivation-validation cohort study

Objective: To determine if non-invasive oxygenation indices, namely peripheral capillary oxygen saturation (SpO2)/ fraction of inspired oxygen (Fi O2) and partial pressure of alveolar oxygen (PAO2)/Fi O2 may be used as effective surrogates for the partial pressure of arterial oxygen (PaO2)/Fi O2. Also, to determine the SpO2/Fi O2 and PAO2/Fi O2 values that correspond to PaO2/Fi O2 thresholds for identifying acute respiratory distress syndrome (ARDS) in patients following coronary artery bypass graft (CABG) surgery. Methods: A prospective derivation-validation cohort study in the Open-Heart ICU of an academic teaching hospital. Recorded variables included patient demographics, ventilator settings, chest radiograph results, and SPO2, PaO2, PAO2, SaO2, and Fi O2. Linear regression modeling was used to quantify the relationship between indices. Receiver operating characteristic (ROC) curves were used to determine the sensitivity and specificity of the threshold values. Results: One-hundred seventy-five patients were enrolled in the derivation cohort, and 358 in the validation cohort. The SPO2/Fi O2 and PAO2/Fi O2 ratios could be predicted well from PaO2/Fi O2, described by the linear regression models SPO2/Fi O2 = 71.149 + 0.8PF and PAO2/Fi O2 = 38.098 + 2.312PF, respectively. According to the linear regression equation, a PaO2/Fi O2 ratio of 300 equaled an SPO2/Fi O2 ratio of 311 (R2 0.857, F 1035.742, < 0.0001) and a PAO2/Fi O2 ratio of 732 (R2 0.576, F 234.887, < 0.0001). The SPO2/Fi O2 threshold of 311 had 90% sensitivity, 80% specificity, LR+ 4.50, LR- 0.13, PPV 98, and NPV 42.1 for the diagnosis of mild ARDS. The PAO2/Fi O2 threshold of 732 had 86% sensitivity, 90% specificity, LR+ 8.45, LR- 0.16, PPV 98.9, and NPV 36 for the diagnosis of mild ARDS. SPO2/ Fi O2 had excellent discrimination ability for mild ARDS (AUC ± SE = 0.92 ± 0.017; 95% CI 0.889 to 0.947) as did PAO2/ Fi O2 (AUC ± SE = 0.915 ± 0.018; 95% CI 0.881 to0.942). Conclusions: PaO2 and SaO2 correlated in the diagnosis of ARDS, with a PaO2/Fi O2 of 300 correlating to an SPO2/ Fi O2 of 311 (Sensitivity 90%, Specificity 80%). The SPO2/ Fi O2 ratio may allow for early real-time rapid identification of ARDS, while decreasing the cost, phlebotomy, blood loss, pain, skin breaks, and vascular punctures associated with serial arterial blood gas measurements
