RESUMO
INTRODUCTION: Broncho-esophageal fistula formation is a rare complication of tuberculosis, most often seen in immunocompromised patients. METHODS AND RESULTS: In this paper, we report the case of a young non-immunocompromised refugee from Somalia diagnosed with open pulmonary tuberculosis complicated by extensive osseous involvement and a broncho-esophageal fistula with consecutive aspiration of gastric contents. The patient rapidly developed a severe acute respiratory distress syndrome (ARDS) requiring venovenous extracorporeal membrane oxygenation (ECMO) therapy for nearly 2 months. The fistula was initially treated by standard antituberculous combination therapy and implantation of an esophageal and a bronchial stent. Long-term antibiotic treatment was instituted for pneumonia and mediastinitis. 7 months later, discontinuity resection of the esophagus was performed and the bronchial fistula covered by an intercostal muscle flap. DISCUSSION: This case illustrates that tuberculosis should always be suspected in patients from high-incidence countries in case of lung involvement and that an interdisciplinary approach including long-term intensive care management can enable successful treatment of tuberculosis with severe, near-fatal complications.

Extracorporeal cardiopulmonary resuscitation (eCPR) may be considered as a rescue attempt for highly selected patients with refractory cardiac arrest and potentially reversible etiology. Currently there are no randomized, controlled studies on eCPR, and valid predictors of benefit and outcome which might guide the indication for eCPR are lacking. Currently selection criteria and procedures differ across hospitals and standardized algorithms are lacking. Based on expert opinion, the present consensus statement provides a proposal for a standardized treatment algorithm for eCPR.

The use of extracorporeal circulatory support, both for cardiogenic shock and during resuscitation, still presents many unanswered questions. The inclusion and exclusion criteria for such a resource-intensive treatment must be clearly defined, considering that these criteria are directly associated with the type and location of treatment. For example, it is worth questioning the viability of an extracorporeal resuscitation program in areas where it is impossible to achieve low-flow times under 60â¯min due to local limitations. Additionally, the best approach for further treatment, including whether it is necessary to regularly relieve the left ventricle, must be explored. To find answers to some of these questions, large-scale, multicenter, randomized studies and registers must be performed. Until then this treatment must be carefully considered before use.

BACKGROUND: Atrial fibrillation (AF) is common among patients in the intensive care unit (ICU) and can be triggered by severe illness or preexisting conditions. It is debated if AF is an independent predictor of poor outcome. METHODS: Data derives from a single center retrospective registry including all patients with a stay on the medical ICU for >24 h. The primary endpoint was ICU survival. Secondary endpoints included receiving mechanical support (renal, respiratory or circulatory), hemodynamic parameters during AF, rate and rhythm control strategies, anticoagulation, and documentation. RESULTS: A total of 616 patients (male gender 62.3%, median age 75 years) were included in our analysis. New-onset AF was diagnosed in 87 patients (14.1%), 136 (22.1%) presented with preexisting AF, and 393 (63.8%) did not develop AF. Initial episodes of new-onset AF exhibited higher hemodynamic instability than episodes in preexisting cases, with elevated heart rates and increased catecholamine doses (both p < 0.001). ICU survival in new-onset AF was 80.5% (70/87) compared to 92.4% (363/393) in patients without AF (OR 0.340, CI 0.182-0.658, p < 0.001). Likewise, ICU survival in preexisting AF was 86.8% (118/136) was significantly lower compared to no AF (OR 0.542, CI 0.290-0.986, p = 0.050*). Independent predictors of ICU survival for patients were atrial fibrillation (p = 0.016), resuscitation before or during ICU stay (p < 0.001), and receiving acute dialysis on ICU (p = 0.002). CONCLUSIONS: ICU survival is noticeably lower in patients with new-onset or preexisting atrial fibrillation compared to those without. Patients who develop new-onset AF during their ICU stay warrant special attention for both short-term and long-term care strategies.

Extracorporeal cardiopulmonary resuscitation (ECPR) is an option for restoring blood circulation in patients with refractory circulatory failure. While conventional resuscitation measures are being continued, venoarterial extracorporeal membrane oxygenation (VA ECMO) is established in patients with cardiac arrest. This bypass can compensate for the functions of the heart and lungs until recovery of organ function. The benefit of ECPR compared to conventional resuscitation appears to be evident, especially after a prolonged resuscitation period; however, in three prospective randomized controlled studies an advantage has not yet been conclusively proven for widespread use in clinical routine. ECPR systems are complex and resource-intensive and should therefore be limited to specialized centers where sufficient numbers of patients are treated to ensure a high level of expertise in the teams.

Standard procedures and guidelines provide specific instructions for basic and advanced cardiac life support. Recommendations for the admission of patients from preclinical into clinical structures after successful cardiopulmonary resuscitation (CPR) are available, but only a few are detailed. In the presence of ST-elevation myocardial infarction after return of spontaneous circulation (ROSC), coronary angiography must be performed as soon as possible. However, acute management and consecutive diagnostic procedures after hospital admission are up to the doctor on duty, who can rely on standard internal hospital procedures at best. Despite the enormous progress and new findings in intensive care and emergency medicine, intra-hospital mortality, as well as long-term survival, after CPR remains low and depends on a wide variety of influencing factors. To optimize in-hospital acute care of successfully resuscitated patients, an interdisciplinary admission team, a so-called cardiac arrest receiving team (CART), has been implemented at the University Hospital of Freiburg, Germany. The aim of the CART is to provide primary care to resuscitated patients as quickly and in as standardized a manner as possible with predefined diagnostic and therapeutic pathways by a team with special expertise in the field of CPR and post-resuscitation management. Accordingly, clear criteria for procedures and the location of primary care (e.g. emergency room vs. cardiac catheter laboratory), the composition of the CART and concrete treatment measures were defined.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a last resort treatment option for refractory cardiac arrest performed in specialized centers. Following consensus recommendations, ECPR is mostly offered to younger patients with witnessed collapse but without return of spontaneous circulation (ROSC). We report findings from a large single-center registry with 252 all-comers who received ECPR from 2011-2019. It took a median of 52 min to establish stable circulation by ECPR. Eighty-five percent of 112 patients with out-of-hospital cardiac arrest (OHCA) underwent coronary angiography, revealing myocardial infarction (MI) type 1 with atherothrombotic vessel obstruction in 70 patients (63% of all OHCA patients, 74% of OHCA patients undergoing coronary angiography). Sixty-six percent of 140 patients with intra-hospital cardiac arrest (IHCA) underwent coronary angiography, which showed MI type 1 in 77 patients (55% of all IHCA patients, 83% of IHCA patients undergoing coronary angiography). These results suggest that MI type 1 is a frequent finding and - most likely - cause of cardiac arrest (CA) in patients without ROSC, especially in OHCA. Hospital survival rates were 30% and 29% in patients with OHCA and IHCA, respectively. According to these findings, rapid coronary angiography may be advisable in patients with OHCA receiving ECPR without obvious non-cardiac cause of arrest, irrespective of electrocardiogram analysis. Almost every third patient treated with ECPR survived to hospital discharge, supporting previous data suggesting that ECPR may be beneficial in CA without ROSC. In conclusion, interventional cardiology is of paramount importance for ECPR programs.

BACKGROUND: Cardiac resynchronisation therapy (CRT) is an established treatment option for chronic heart failure patients with left bundle branch block. Although a concomitant functional mitral regurgitation is often reduced by CRT, many patients need additional mitral valve repair. Placing a CARILLON® Mitral Contour System (CMCS) over a transvenous CRT lead is currently not recommended, since both of them are implanted in the coronary sinus (CS). The aim of this study was to investigate the feasibility of sequential implantation of a transvenous LV lead followed by CMCS implantation, and to assess LV lead performance and possibility of extraction. METHODS AND RESULTS: Standard transvenous LV leads were implanted in the CS of five female sheep. After establishing regular anatomical position with stable electrical parameters of the LV lead, a CMCS was additionally implanted in the CS. After an observation period of 100 days, lead performance and positions of lead and CMCS were studied. Sequential implantation of the two components was feasible in sheep. After 100 days, all leads showed regular measurements of impedance, threshold, and sensing. There was no migration of either the LV lead or the CMCS. In all cases, the LV lead could be completely extracted without migration of the CMCS. There were no acute or long-term complications. CONCLUSIONS: In an animal model of healthy adult sheep, implantation of CMCS with a transvenous LV lead already in place was feasible and without major problems with either the CMCS or the LV lead. Electrical performance of the LV leads was excellent. All LV leads could be extracted without migration of the CMCS.

Aberrant activity of the signal transducer and activator of transcription 3 (Stat3) is believed to be essential for neoplastic cell behaviour and thus for the malignancy of tumor cells [Bowman T, Garcia R, Turkson J, Jove R. STATs in oncogenesis. Oncogene 2000;19:2474-88]. Extravillous trophoblast cells resemble malignancies in their invasive and destructive features, excluding the fact of sequential restriction to the first trimester of pregnancy. Trophoblast cells from term placentas have reduced invasive capacity [Hohn HP, Denker HW. Experimental modulation of cell-cell adhesion, invasiveness and differentiation in trophoblast cells. Cells Tissues Organs 2002;172:218-36]. Constitutively activated Stat3 DNA-binding activity in choriocarcinoma cells, carcinomatous derivates of trophoblast cells, have been reported to correlate with its invasiveness [Corvinus FM, Fitzgerald JS, Friedrich K, Markert UR. Evidence for a correlation between trophoblast invasiveness and STAT3 activity. Am J Reprod Immunol 2003;50:316-21]. Here we demonstrate using RNAi that Stat3 activation is necessary in the invasive phenotype of trophoblast cells and can be controlled via Leukemia Inhibitory Factor (LIF). LIF provides a soluble extracellular signal that stimulates invasion in trophoblast and Jeg-3 choriocarcinoma cells. Loss of LIF-mediated invasion in these cells subsequent to STAT3 knock-down strongly suggests that STAT3 plays a crucial role in mediating this invasion.

BACKGROUND: The recently introduced Freiburg index of patient satisfaction (FIPS) is a new questionnaire to assess treatment-related patient satisfaction after surgery and interventional procedures. The questionnaire had first been tested psychometrically in a mixed population of urology patients. The current study describes the results of an interdisciplinary validation. In addition, an English version is presented. METHODS: The questionnaire was used in two cohorts of cardiology (n = 120) and surgical (n = 127) patients. The evaluation included a comprehensive methodological and statistical evaluation including validation in comparison to the ZUF-8 questionnaire. RESULTS: The psychometric evaluation showed good results. The analyzed samples showed no missing values or ceiling effects. Furthermore, a high reliability (Cronbach's alpha 0.82), unidimensionality, sufficient distribution of values and validity (high correlation to the ZUF-8, r = 0.65, p < 0.001) of the questionnaire could be confirmed. CONCLUSIONS: The FIPS constitutes an interdisciplinary validated questionnaire to evaluate treatment-related patient satisfaction which can be used to objectify and compare results from clinical studies and quality in patient care. Colleagues of English-speaking countries are invited to participate in the validation of the hereby presented English version.
