Effects of an early rehabilitation program for adult cystic fibrosis patients during hospitalization: a randomized clinical trial.

There is little information on pulmonary rehabilitation in patients with cystic fibrosis (CF) with pulmonary exacerbation. This study aimed to evaluate the effects of an early rehabilitation program on lung function, muscle strength, inflammatory markers, and quality of life in adults with CF hospitalized for pulmonary exacerbation. In this randomized controlled trial, 19 patients were included in the intervention group and 15 in the control group. The intervention group underwent an early rehabilitation program for 14 days after admission. All patients underwent spirometry, one-repetition maximum tests (1RM), and the 6-min walk test, and answered the Revised Cystic Fibrosis Questionnaire (CFQ-R) for quality of life and the International Physical Activity Questionnaire. Serum levels of interleukin and tumor necrosis factor alpha (TNF-α) were measured. In the intervention group, there were increases in 1RM biceps (P=0.009), triceps (P=0.005), shoulder abductors (P=0.002), shoulder flexors (P=0.004), hamstrings (P<0.001), and quadriceps values (P<0.001). In addition, there were improvements in CFQ-R-emotion (P=0.002), treatment burden (P=0.002), vitality (P=0.011), and physical scores (P=0.026), and a reduction in the Borg resting fatigue score (P=0.037). The interleukins levels did not change after the intervention. In adult CF patients with pulmonary exacerbation, early hospital rehabilitation had a significant impact on improving resting fatigue, muscle strength, and quality of life.

[Anesthesiological aspects in patients with epidermolysis bullosa]. / Anästhesiologische Aspekte bei Patienten mit Epidermolysis bullosa.

Epidermolysis bullosa causes blistering due to altered structural proteins of the dermoepidermal junction, resulting in scarring and strictures of the skin and mucous membranes. Affected individuals typically require frequent surgical interventions due to burdensome symptoms and complications of the disease. The anesthesiological management of these patients is inherently challenging. This review article summarizes the relevant features of this patient cohort and provides practical recommendations for care.

Functional capacity, lung function, and muscle strength in patients undergoing hematopoietic stem cell transplantation: A prospective cohort study.

OBJECTIVE/BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a treatment for benign and malignant hematological diseases. These aggressive treatments cause reduced levels of physical activity, decreased lung function, and worse quality of life. Alterations in pulmonary function tests before HSCT are associated with the risk of respiratory failure and early mortality. The objective of this study was to evaluate functional capacity and lung function before and after HSCT and identify the predictors of mortality after 2 years. METHODS: A prospective cohort study was carried out with individuals with oncohematological diseases. The evaluations were carried out in two moments during hospitalization and at hospital discharge. Follow-up was carried out after 48 months. Assessments were carried out on 34 adults, using spirometry, manovacuometry, 6-Minute Walk Test (6MWT), Handgrip Strength Test, and 30-Second Chair Stand Test (30-s CST). RESULTS: There was a statistically significant reduction for the variables in forced vital capacity, forced expiratory volume predicted in the 1st second, Tiffeneau index, handgrip strength, and distance covered (% predicted) on the 6MWT (p < .05). There was a significant difference in the 30-s CST when individuals were compared according to the type of transplant. We found that a 10% reduction in the values of maximum inspiratory pressure (MIP) can predict an increased risk for mortality. CONCLUSIONS: Individuals undergoing HSCT have reduced functional capacity, lung function, and muscle strength during the hospitalization phase. Reduction in the values of MIP increases the risk of nonrelapse mortality.

A prospective observational study of the rapid detection of clinically-relevant plasma direct oral anticoagulant levels following acute traumatic injury.

In urgent clinical situations, such as trauma, urgent surgery or before thrombolysis, rapid quantification of direct oral anticoagulant plasma drug levels is warranted. Using the ClotPro® analyser, we assessed two novel viscoelastic tests for detection of clinically-relevant plasma drug levels in trauma patients. The ecarin clotting time was used to assess the plasma concentration of dabigatran and Russell´s viper venom clotting time to determine the plasma concentration of direct factor Xa inhibitors. In parallel, plasma concentrations were analysed using plasma-based chromogenic assays. A total of 203 simultaneous measurements were performed. Strong to very strong linear correlations were detected between ecarin clotting time and plasma concentration of dabigatran (r = 0.9693), and between Russell´s viper venom clotting time and plasma concentrations of apixaban (r = 0.7391), edoxaban (r = 0.9251) and rivaroxaban (r = 0.8792), all p < 0.001. An ecarin clotting time ≥ 189 seconds provided 100% sensitivity and 90% specificity for detecting plasma dabigatran concentrations ≥ 50 ng.ml-1 . Corresponding Russell´s viper venom clotting time cut-off values were ≥ 136 seconds for apixaban (80% sensitivity, 88% specificity), ≥ 168 seconds for edoxaban (100% sensitivity, 100% specificity) and ≥ 177 seconds for rivaroxaban (90% sensitivity, 100% specificity). Detection of drug levels ≥ 100 ng.ml-1 was also investigated: for dabigatran, an ecarin clotting time ≥ 315 seconds yielded 92% sensitivity and 100% specificity; while Russell´s viper venom clotting time cut-offs of 191, 188 and 196 seconds were calculated for apixaban (67% sensitivity, 88% specificity), edoxaban (100% sensitivity, 75% specificity) and rivaroxaban (100% sensitivity, 91% specificity), respectively. We have demonstrated strong positive correlations between plasma drug levels and clotting time values in the specific ClotPro assays. Cut-off values for detecting clinically-relevant drug levels showed high levels of sensitivity and specificity.

Random-pattern versus perforator-based adipocutaneous skin paddles for postoperative monitoring of free muscle flaps-a comparative retrospective cohort study.

INTRODUCTION: Free microvascular muscle flaps represent well-established reconstructive options for complex soft tissue defects. However, due to their lack of cutaneous capillary beds, they are difficult to monitor postoperatively. To this end, random and axial-pattern adipocutaneous skin paddles are often included. The objective of the study was to compare the impact of random-pattern versus perforator-based adipocutaneous skin paddles on operative efficacy and muscle flap safety. METHODS: Between August 2014 and July 2016, a total of 120 free muscle flaps were included in this retrospective monocentric cohort study. Based on their skin-paddle type, they were either grouped into a 'perforator-based' (group Pb) or 'random-pattern' (group Rp) cohort. The electronic medical records and operative reports of all patients were subsequently reviewed and patient, defect, and flap characteristics of both groups were compared. The effect of the competing skin paddle types on the overall operative time, incidences of flap loss or microvascular complications, and total length of hospital stay were then assessed. RESULTS: Group Pb comprised 72 flaps, whereas 48 flaps constituted group Rp. Patient, defect, and flap characteristics were similar between both groups. Groups Pb and Rp were comparable regarding patient age (group Pb: 61 (10-90) vs. Rp: 59 (13-81), p = 0.556), ASA (American Society of Anesthesiologists) class (group Pb: 3 (1-4) vs. Rp 3 (1-3), p = 0.977), and comorbidities, summarized by the Charlson comorbidity index (CCI; group Pb: 1 (0-4 vs. Rp: 1 (0-5), p = 0.295). Both types of monitoring skin paddles were equally reliable. There was no significant difference in the mean operation time between both groups (group Pb: 373 ±â€¯122 min vs. Rp: 342 ±â€¯84 min, p = 0.124). In-patient treatment after flap surgery and total length of hospital stay were significantly shorter in group Pb (group Pb: 24 ±â€¯10 days vs. Rp: 32 ±â€¯17 days, p = 0.002 and group Pb: 39 ±â€¯15 vs. Rp: 48 ±â€¯24, p = 0.022). CONCLUSION: Perforator-based skin paddles are a reliable tool for postoperative perfusion monitoring of free muscle flaps and help avoid additional surgical interventions as opposed to their random-pattern counterparts. Thus, the overall and postoperative length of hospital stay is significantly reduced.

Evidence of stage progression in a novel, validated fluorescence-navigated and microsurgical-assisted secondary lymphedema rodent model.

Secondary lymphedema (SL)is a frequent and devastating complication of modern oncological therapy and filarial infections. A lack of a reliable preclinical model to investigate the underlying mechanism of clinical stage progression has limited the development of new therapeutic strategies. Current first line treatment has shown to be merely symptomatic and relies on lifetime use of compression garments and decongestive physiotherapy. In this study, we present the development of a secondary lymphedema model in 35 rats using pre- and intraoperative fluorescence-guided mapping of the lymphatics and microsurgical induction. In contrast to the few models reported so far, we decided to avoid the use of radiation for lymphedema induction. It turned out, that the model is nearly free of complications and capable of generating a statistically significant limb volume increase by water displacement measurements, sustained for at least 48 days. A translational, accurate lymphatic dysfunction was visualized by a novel VIS-NIR X-ray ICG-Clearance-Capacity imaging technology. For the first-time SL stage progression was validated by characteristic histological alterations, such as subdermal mast cell infiltration, adipose tissue deposition, and fibrosis by increased skin collagen content. Immunofluorescence confocal microscopy analysis suggested that stage progression is related to the presence of a characteristic α SMA+/HSP-47+/vimentin+ fibroblast subpopulation phenotype. These findings demonstrate that the in-vivo model is a reliable and clinically relevant SL model for the development of further secondary lymphedema therapeutic strategies and the analysis of the veiled molecular mechanisms of lymphatic dysfunction.

Detection of osteoarthritis using acoustic emission analysis.

Osteoarthritis (OA) of the knee is a widespread disease, often resulting in pain, restricted mobility and a reduction of activities and participation. Initial studies gave hints that Acoustic Emission Analysis (AEA) is capable of detecting early changes in cartilage structure. However, up to date no in vivo validation studies have been conducted. A prospective pilot study was conducted to investigate this diagnostic capability and the accuracy of the AEA, using magnetic resonance imaging (MRI) as a reference standard. Additionally, potential factors influencing false positive or negative results were studied. Twenty-eight patients, receiving MRI due to discomfort of the knee, were examined with AEA. Sensitivity was 0.92 for the whole knee and 0.86 to 1 for different parts of the knee. The specificity was 0.7 and 0.59 to 0.78, respectively. Confidence intervals varied between 0 and 0.33 for sensitivity and 0.1 and 0.24 for specificity. The diagnostic accuracy of the AEA was shown to be good to very good. However, because of the relatively small number of patients involved, interpretation of the data should be handled with care. Future studies with greater sample sizes have to be conducted to confirm the results of this investigation.

Relationships between early-life growth, intake, and birth season with first-lactation performance of Holstein dairy cows.

The objective was to determine the relationships between early-life parameters [including average daily gain (ADG), body weight (BW), milk replacer intake, starter intake, and birth season] and the first-lactation performance of Holstein cows. We collected data from birth years 2004 to 2012 for 2,880 Holstein animals. Calves were received from 3 commercial dairy farms and enrolled in 37 different calf research trials at the University of Minnesota Southern Research and Outreach Center from 3 to 195 d. Upon trial completion, calves were returned to their respective farms. Milk replacer options included varying protein levels and amounts fed, but in the majority of studies, calves were fed a milk replacer containing 20% crude protein and 20% fat at 0.57 kg/calf daily. Most calves (93%) were weaned at 6 wk. Milk replacer dry matter intake, starter intake, ADG, and BW at 6 wk were 21.5 ± 2.2 kg, 17.3 ± 7.3 kg, 0.53 ± 0.13 kg/d, and 62.4 ± 6.8 kg, respectively. Average age at first calving and first-lactation 305-d milk yield were 715 ± 46.5 d and 10,959 ± 1,527 kg, respectively. We conducted separate mixed-model analyses using the REML model-fitting protocol of JMP (SAS Institute Inc., Cary, NC) to determine the effect of early-life BW or ADG, milk replacer and starter intake, and birth season on first-lactation 305-d milk, fat, and true protein yield. Greater BW and ADG at 6 wk resulted in increased first-lactation milk and milk component yields. Intake of calf starter at 8 wk had a significant positive relationship with first-lactation 305-d yield of milk and milk components. Milk replacer intake, which varied very little in this data set, had no effect on first-lactation 305-d yield of milk and milk components. Calves born in the fall and winter had greater starter intake, BW, and ADG at 8 wk. However, calves born in the summer had a higher 305-d milk yield during their first lactation than those born in the fall and winter. Improvements were modest, and variation was high, suggesting that additional factors not accounted for in these analyses affected first-lactation performance.

Randomized crossover study assessing oropharyngeal leak pressure and fiber optic positioning : Laryngeal Mask Airway Supreme™ versus Laryngeal Tube LTS II™ size 2 in non-paralyzed anesthetized children.

BACKGROUND: As there are currently no data available comparing the practicability of the laryngeal mask airway (LMA) Supreme™ size 2 versus the laryngeal tube LTS II™ size 2 in children, this trial was conducted to quantify the differences between these two airway devices concerning leak pressure and fiber optic-controlled positioning in non-paralyzed, anesthetized pediatric patients. METHODS: A total of 56 children aged 1-6 years and weighing between 11 and 23 kg were enrolled in the study. Anesthesia was intravenously induced according to local standards using fentanyl and propofol. After induction of anesthesia both airway devices were inserted consecutively in accordance with the randomization protocol. RESULTS: The mean oropharyngeal leak pressure was significantly higher for the LTS II™ (33±8 cmH2O) than for the LMA Supreme™ (21±7 cmH2O, p < 0.0001). Fiber optic position monitoring was better when the LMA Supreme™ was used (p  < 0.001). The first attempt success rates for insertion (55Supreme LMA vs. 43LTSII, p < 0.001), the insertion time (25 s Supreme LMA vs. 34 s LTSII, p < 0.04) and the frequency of bloodstaining (0Supreme LMA vs 4LTSII, p < 0.04) for the initially used device were better for the LMA Supreme™ than the laryngeal tube LTS II™. CONCLUSION: We conclude that oropharyngeal leak pressure, fiber optic position, first attempt insertion success rate and bloodstaining differed between the LMA Supreme™ and the LTS II™ in children.

Suprathel(®) for severe burns in the elderly: Case report and review of the literature.

Large burns in aged patients are common and treatment often reveals challenging. Cardiovascular complications significantly contribute to the unfavorable prognosis in this group of high-risk patients. Pain medication and sedation can negatively influence cardiovascular stability. Suprathel(®) is well-known for its almost pain free application and reduction of dressing change intervals, and thus lowers the demand for potentially harmful analgesics and sedatives. We present the case of an 81-year-old patient with 51% of total burned body surface area (ABSI=12), who was completely treated with Suprathel(®). Despite a predicted mortality of more than 80%, the patient survived and was discharged home without significant handicaps 69 days after burn. We hypothesize that Suprathel(®) beneficially contributed to the favorable clinical course of this critical patient as less frequent wound-dressing changes did not induce additional pain or sedative medication and thus improved cardiovascular stability.

Next-generation sequencing identifies major DNA methylation changes during progression of Ph+ chronic myeloid leukemia.

Little is known about the impact of DNA methylation on the evolution/progression of Ph+ chronic myeloid leukemia (CML). We investigated the methylome of CML patients in chronic phase (CP-CML), accelerated phase (AP-CML) and blast crisis (BC-CML) as well as in controls by reduced representation bisulfite sequencing. Although only ~600 differentially methylated CpG sites were identified in samples obtained from CP-CML patients compared with controls, ~6500 differentially methylated CpG sites were found in samples from BC-CML patients. In the majority of affected CpG sites, methylation was increased. In CP-CML patients who progressed to AP-CML/BC-CML, we identified up to 897 genes that were methylated at the time of progression but not at the time of diagnosis. Using RNA-sequencing, we observed downregulated expression of many of these genes in BC-CML compared with CP-CML samples. Several of them are well-known tumor-suppressor genes or regulators of cell proliferation, and gene re-expression was observed by the use of epigenetic active drugs. Together, our results demonstrate that CpG site methylation clearly increases during CML progression and that it may provide a useful basis for revealing new targets of therapy in advanced CML.

Dyspnea perception in cystic fibrosis patients.

We evaluated dyspnea perception in cystic fibrosis patients compared with normal subjects, during an inspiratory resistive loading test and 6-min walk test. We also evaluated the correlation between dyspnea scores induced by resistive loads and by the 6-min walk test. In this prospective, cross-sectional study, 31 patients with cystic fibrosis (≥15 years of age) and 31 age-, gender-, and ethnicity-matched healthy volunteers (20 females and 11 males per group) underwent inspiratory resistive loading, spirometry, and the 6-min walk test. As the magnitude of the inspiratory loads increased, dyspnea scores increased (P<0.001), but there was no difference between groups in dyspnea score (P=0.654). Twenty-six (84%) normal subjects completed all the resistive loads, compared with only 12 (39%) cystic fibrosis patients (P<0.001). Dyspnea scores were higher after the 6-min walk test than at rest (P<0.001), but did not differ between groups (P=0.080). Post-6-min walk test dyspnea scores correlated significantly with dyspnea scores induced by resistive loads. We conclude that dyspnea perception induced in cystic fibrosis patients by inspiratory resistive loading and by 6-min walk test did not differ from that induced in normal subjects. However, cystic fibrosis patients discontinued inspiratory resistive loading more frequently. There were significant correlations between dyspnea perception scores induced by inspiratory resistance loading and by the 6-min walk test. This study should alert clinicians to the fact that some cystic fibrosis patients fail to discriminate dyspnea perception and could be at risk for delay in seeking medical care.

Domain wall roughness in stripe phase BiFeO3 thin films.

Using the model system of ferroelectric domain walls, we explore the effects of long-range dipolar interactions and periodic ordering on the behavior of pinned elastic interfaces. In piezoresponse force microscopy studies of the characteristic roughening of intrinsic 71° stripe domains in BiFeO3 thin films, we find unexpectedly high values of the roughness exponent ζ=0.74±0.10, significantly different from those obtained for artificially written domain walls in this and other ferroelectric materials. The large value of the exponent suggests that a random field-dominated pinning, combined with stronger disorder and strain effects due to the step-bunching morphology of the samples, could be the dominant source of pinning in the system.

Hyperfibrinolysis is common in out-of-hospital cardiac arrest: results from a prospective observational thromboelastometry study.

BACKGROUND: Cardiocirculatory arrest (CCA) activates procoagulant pathways. It has also been reported to inhibit fibrinolysis, resulting in fibrin deposition and further impairment of blood flow. Until now, no studies have used whole-blood viscoelastic tests to characterize coagulation and the impact of fibrinolysis in out-of-hospital cardiac arrest (OHCA). METHODS: Patient with established OHCA who underwent cardiopulmonary resuscitation (CPR) were enrolled. Blood samples were obtained immediately after placement of an intravenous line at the scene, for full blood cell count, standard coagulation tests and rotational thromboelastometric (ROTEM(®)) analyses. Patients with return of spontaneous circulation (ROSC) were compared to non-ROSC patients. RESULTS: Fifty-three patients (median age 67 years, interquartile range: 56-73 years) were included in the study. ROSC was established in 25 patients. Prothrombin time index (PTI) was significantly lower and activated partial thromboplastin time (aPTT) was significantly prolonged in non-ROSC patients compared to ROSC patients. Clotting time (CT) in the extrinsically activated ROTEM test (EXTEM) was significantly longer in non-ROSC versus ROSC patients. For the remaining EXTEM parameters, there were no significant differences between ROSC and non-ROSC patients. Hyperfibrinolysis (maximum lysis>15% according to ROTEM test results) was observed in 19 patients (35.8%). There was no difference between ROSC and non-ROSC patients in the incidence of hyperfibrinolysis. CONCLUSIONS: PTI, aPTT and EXTEM CT revealed significant differences between ROSC and non-ROSC patients. Hyperfibrinolysis according to ROTEM test results was much more common than previously assumed. Routine use of fibrinolytic therapy in all patients with prolonged CPR cannot therefore be recommended.

Nanoscale polarization switching mechanisms in multiferroic BiFeO3 thin films.

Ferroelectric switching in BiFeO3 multiferroic thin films was studied by piezoresponse force microscopy, as a function of the tip voltage and sweep direction, for samples with two different intrinsic domain structures. In all films, the switched polarization direction follows the in-plane and out-of-plane components of the highly inhomogeneous electric field applied by the microscope tip. In films with 'bubble-like' intrinsic domains, we observed in-plane switching assisted by out-of-plane switching for lower voltage values, and independent in-plane and out-of-plane switching for higher voltages, in both cases allowing full control of the ferroelectric polarization depending on the tip voltage polarity and sweep direction. In films with 'stripe-like' intrinsic domains, independent in-plane and out-of-plane switching was observed, but unswitched stripe domains prevented full control of the ferroelectric polarization over large areas. We correlate the observed switching behavior with the field-driven onset of a highly distorted tetragonal phase predicted by ab initio calculations, which leads to a very high in-plane susceptibility during the return to the non-distorted monoclinic phase when the field is decreased. Depending on the specific strain and disorder present in the sample, the transition towards the highly distorted phase may be asymmetrized, and easier to reach when an electric field opposite to the out-of-plane polarization direction is applied.

Peri-operative management of antiplatelet therapy in patients with coronary artery disease: joint position paper by members of the working group on Perioperative Haemostasis of the Society on Thrombosis and Haemostasis Research (GTH), the working group on Perioperative Coagulation of the Austrian Society for Anesthesiology, Resuscitation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society for Cardiology (ESC).

An increasing number of patients suffering from cardiovascular disease, especially coronary artery disease (CAD), are treated with aspirin and/or clopidogrel for the prevention of major adverse events. Unfortunately, there are no specific, widely accepted recommendations for the perioperative management of patients receiving antiplatelet therapy. Therefore, members of the Perioperative Haemostasis Group of the Society on Thrombosis and Haemostasis Research (GTH), the Perioperative Coagulation Group of the Austrian Society for Anesthesiology, Reanimation and Intensive Care (ÖGARI) and the Working Group Thrombosis of the European Society of Cardiology (ESC) have created this consensus position paper to provide clear recommendations on the perioperative use of anti-platelet agents (specifically with semi-urgent and urgent surgery), strongly supporting a multidisciplinary approach to optimize the treatment of individual patients with coronary artery disease who need major cardiac and non-cardiac surgery. With planned surgery, drug eluting stents (DES) should not be used unless surgery can be delayed for ≥12 months after DES implantation. If surgery cannot be delayed, surgical revascularisation, bare-metal stents or pure balloon angioplasty should be considered. During ongoing antiplatelet therapy, elective surgery should be delayed for the recommended duration of treatment. In patients with semi-urgent surgery, the decision to prematurely stop one or both antiplatelet agents (at least 5 days pre-operatively) has to be taken after multidisciplinary consultation, evaluating the individual thrombotic and bleeding risk. Urgently needed surgery has to take place under full antiplatelet therapy despite the increased bleeding risk. A multidisciplinary approach for optimal antithrombotic and haemostatic patient management is thus mandatory.

[Vaccination status in very and extremely preterm infants at the age of 2 years--a nationwide pilot analysis]. / Impfstatus bei Frühgeborenen mit einem Geburtsgewicht unter 1500 g im Alter von 2 Jahren--eine deutschlandweite Piloterhebung.

Preterm infants are at increased risk of suffering from vaccine preventable diseases. Therefore it is recommended to vaccinate them in time at the same chronological age as full term infants. Several reports have shown that vaccinations of very and extreme low birth weight infants are often delayed but till now there are no data for Germany. Our study analysed the vaccination rates and suffered complications of 318 preterm infants with birth weights under 1 500 g at the age of 2 years from all over the country copying their vaccination-record and asking the parents to answer a questionnaire. The preterm infants received the first 3 doses of the pentavalent or hexavalent vaccines consequently (1st dose: 100%, 2nd dose: 100%, 3rd dose: 97.5%), whereas the booster dose was accomplished to a lesser extent (89.0%) during their second year of life. The majority of the vaccinations were administered delayed. Moreover, the preterm infants received the first doses of the pneumococcal conjugate vaccine and the measles-mumps-rubella vaccine quite consequently, but the booster dose was again injected less frequent. According to their parents 17.8% of these preterm infants suffered from non-severe adverse reactions and none of them had an episode of apnoea following the immunisation. In conclusion preterm infants in Germany receive their basic immunisations consequently, but often too late. There is still the need to improve the frequency of the booster dose application especially in the second year of life and to prevent delays of vaccinations.
