description: Aim of the study was to develop a standardized model system to investigate endodontic irrigation techniques and assess the efficiency of different activation methods on the removal of hard tissue debris in complex root canal systems. Mesial roots of mandibular molars were firstly scanned by micro-computed tomography (mu CT) and allocated to three groups of irrigant activation: sonic activation (EDDY, VDW, Munich, Germany), laser activation (AutoSWEEPS, FOTONA, Ljubljana, Slovenia) and conventional needle irrigation (control). Roots were fixed in individual 3D-printed holders to facilitate root canal enlargement under constant irrigation with NaOCl (5%). To enable standardized quantification of remaining debris, BaSO4-enriched dentine powder was compacted into the canals, followed by another mu CT-scan. The final irrigation was performed using 17% ethylenediaminetetraacetic acid (EDTA) and 5% sodium hypochlorite (NaOCl) with the respective activation method, and the volume of remaining artificial debris was quantified after a final mu CT-scan. The newly developed model system allowed for reliable, reproducible and standardized assessment of irrigation methods. Activation of the irrigant proved to be significantly more effective than conventional needle irrigation regarding the removal of debris, which persisted particularly in the apical third of the root canal in the control group. The efficiency of irrigation was significantly enhanced with laser- and sonic-based activation, especially in the apical third.

description: Background: Sepsis is a leading cause of morbidity and mortality worldwide. Many patients suffering from sepsis are treated on intensive care units and many of them require mechanical ventilation under sedation or general anesthesia. Propofol, a drug used for these purposes, is known to interact with polymorphonuclear granulocytes (PMNs). Therefore, the aim of this study was to investigate the influence of propofol on PMN functions after experimental Gram-negative induced sepsis using lipopolysaccharide (LPS) stimulation. Methods: A total of 34 granulocyte-enriched samples were collected from healthy subjects. PMNs were isolated by density gradient centrifugation and incubated simultaneously with either 6 mu g/mL or 60 mu g/mL propofol, or none (control). Additionally, the experimental sepsis samples were incubated with either 40 pg/mL or 400 pg/mL LPS. Live cell imaging was conducted in order to observe granulocyte chemotactic migration, ROS production, and NETosis. Flow cytometry was used to analyze viability and antigen expression. Results: Propofol led to significantly reduced PMN track length (p < 0.001) and track speed (p < 0.014) after LPS-induced sepsis in a dose-dependent manner. NETosis (p = 0.018) and ROS production (p = 0.039) were accelerated by propofol without LPS incubation, indicating improved immune function. Propofol also ameliorated LPS-induced increased NETosis and ROS-production. Antigen expression for CD11b, CD62l and CD66b was unaffected by propofol. Conclusion: Propofol improves LPS-induced exaggerated PMN activation in an ex vivo model. Beneficial effects due to restored immune function in septic patients might be possible, but needs further investigation.

description: In öffentlichen Repositorien finden sich inzwischen massenhaft Forschungsdaten die für studienübergreifende Analysen verwendet werden können. Solche übergreifenden Analysen sind wichtig, da Einzelstudien oft nur begrenzte Aussagekraft haben – etwas aufgrund zu geringer Stichprobenumfänge. Durch die Fusion der Daten mehrerer Studien oder durch Meta-Analysen können Forschungsergebnisse einen höheren Grad wissenschaftlicher Evidenz erhalten. Öffentlich zugängliche Forschungsdaten sind daher inzwischen zu einer wichtigen Säule der Wissenschaft geworden.

Diese Coffee-Lecture stellt einige Tools für solche zusammenfassenden Analysen vor und beantwortet Fragen, was bei der Veröffentlichung von Forschungsdaten zu beachten ist, damit sie für solche Analysen in Betracht gezogen werden können.

subject: 610 Medizin

description: Background: 
Total Hip Arthroplasty (THA) is one of the most commonly performed and successful orthopaedic surgeries. At the same time, the issue about the best surgical approach for THA remains controversial. This systematic review aims to evaluate the current evidence for the use of Minimally-Invasive Surgery (MIS) in THA.

Methods: 
A systematic literature search of PubMed, Medline and Embase was conducted. Randomised controlled trials, comparative studies, and cohort studies were included in this systematic review. Main outcome measurements included incision length, blood loss, operating time, length of stay, complications, postoperative pain on a Visual Analogue Scale (VAS), Short Form 36/12 Health Survey (SF 36/12), Harris Hip Score (HHS) and cup inclination.

Results: 
A total of 30 studies met the inclusion criteria. There was no significant difference between MIS and conventional approaches for THA with regards to complication rates and implant inclination angle. The average operating time in 10/24 (41%) studies was significantly (p<0.05) longer in the MIS group. MIS THA lead to an improvement, patient-centered results with reduced blood loss in 9/16 (56%), reduced use of analgesics in 4/4 (100%) and reduced myoglobin correlated muscle trauma in 3/4 (75%) of the analysed studies. Additionally, 10/10 (100%) studies reported less postoperative pain after MIS THA, 16/19 (84%) studies detected an improved postoperative Harris Hip score and 7/7 (100%) studies an improved SF36/12 score respectively. This resulted a reduced length of stay in 10/10 (100%) of the studies when compared to THA utilizing a conventional approach.

Conclusion: 
MIS in THA is nowadays no longer seen as just cosmetically attractive but rather as a real improvement for the clinical outcome. There is evidence for improved patient related outcome following MIS THA.
Auricular Acupressure Combined with Self-Help Intervention for Treating Chronic Tinnitus: A Longitudinal Observational Study

description: Tinnitus is a phantom sound perception in the ears or head and can arise from many different medical disorders. Currently, there is no standard treatment for tinnitus that reliably reduces tinnitus. Individual patients reported that acupressure at various points around the ear can help to reduce tinnitus, which was investigated here. With this longitudinal observational study, we report a systematic evaluation of auricular acupressure on 39 tinnitus sufferers, combined with a self-help smartphone app. The participants were asked to report on tinnitus, stress, mood, neck, and jaw muscle tensions twice a day using an ecological momentary assessment study design for six weeks. On average, 123.6 questionnaires per person were provided and used for statistical analysis. The treatment responses of the participants were heterogeneous. On average, we observed significant negative trends for tinnitus loudness (Cohen's d effect size: -0.861), tinnitus distress (d = -0.478), stress (d = -0.675), and tensions in the neck muscles (d = -0.356). Comparison with a matched control group revealed significant improvements for tinnitus loudness (p = 0.027) and self-reported stress level (p = 0.003). The positive results of the observational study motivate further research including a randomized clinical trial and long-term assessment of the clinical improvement.

description: Tooth agenesis is a common congenital anomaly in humans and is more common in oral cleft patients than in the general population. Many previous studies suggested that oral cleft and tooth agenesis share a similar genetic background. Therefore, this study explored the association between isolated tooth agenesis and genetic polymorphisms in genes that are crucial for craniofacial and tooth development. Panoramic radiographs, anamnesis, and genomic DNA from 273 patients were included. Patients were classified as tooth agenesis present, when at least one permanent tooth was congenitally missing. Patients with syndromes and oral cleft were excluded. Only unrelated patients were included. The genetic polymorphisms in BMP2 (rs235768 and rs1005464), BMP4 (rs17563), RUNX2 (rs59983488 and rs1200425), and SMAD6 (rs3934908 and rs2119261) were genotyped by real-time polymerase chain reaction. Genotype and allele distributions were compared between the tooth agenesis phenotypes and controls by Chi-square test. Haplotype and diplotype analysis were also performed, in addition to multivariate analysis (alpha of 0.05). A total of 86 tooth agenesis cases and 187 controls were evaluated. For the rs235768 in BMP2, patients carrying TT genotype have higher chance to present tooth agenesis [p < 0.001; prevalence ratio (PR) = 8.29; 95% confidence interval (CI) = 4.26-16.10]. The TT genotype in rs3934908 (SMAD6) was associated with higher chance to present third molar agenesis (p = 0.023; PR = 3.25; 95% CI = 1.17-8.99). BMP2 was also associated in haplotype and diplotype analysis with tooth agenesis. In conclusion, genetic polymorphisms in BMP2 and SMAD6 were associated with isolated tooth agenesis.

description: The present study analysed current rehabilitation protocols to investigate whether there is a standard for early rehabilitation after microfracturing (MFX), matrix-assisted cartilage transplantation (MACT), and osteochondral autograft transfer (OATS) of the knee joint in clinical routine, and if rehabilitation protocols differ in the repair technique used or the localization of the cartilage defect. The evaluation included rehabilitation criteria such as weight-bearing, range of motion, use of an orthosis, motion therapy, and rehabilitation training during the early rehabilitation phase after MFX, MACT, and OATS of the femorotibial and retropatellar joint space. We analysed 153 rehabilitation protocols after cartilage repair of the knee joint, including 137 protocols for after repair of the main weight-bearing (femorotibial) area and 16 for after retropatellar cartilage repair. Most of the protocols differed significantly according to the location of the repair and the procedure performed. Our findings indicate that full weight-bearing can be achieved significantly faster after MFX (5.6 weeks) and OATS (5.3 weeks) than after MACT of the main weight-bearing zone (6.6 weeks, p < 0.001). In addition, after retropatellar cartilage repair, patients are allowed full weight-bearing after 2.1 weeks compared to the main weight-bearing zone (5.3-6.6 weeks; p < 0.001). No standardized rehabilitation recommendations have been established. The present study shows that rehabilitation needs to be adjusted to the surgical technique and the location of the defect zone, and further investigation is warranted to establish standardized rehabilitation protocols after cartilage repair of the knee joint.

description: Background: In adults, intussusception has been considered traditionally to have an underlying aetiology. The aim of this study was to determine CT and clinical features of small-bowel intussusceptions that required surgical intervention. Methods: Adult patients were identified in whom small-bowel intussusceptions were noted on CT images. The appearance, number, type (enteroenteric versus enterocolic), length and maximum short-axis diameter of intussusceptions, and presence of bowel obstruction (short-axis diameter of proximal small bowel greater than 3 cm) were analysed. The outcome was defined as surgical (complicated) or self-limiting (uncomplicated). Associations between complicated and uncomplicated intussusceptions and patient characteristics were investigated. Results: Among 75 patients (56 male) with a mean age of 45 years, 103 intussusceptions were identified, of which 98 (95 per cent) were enteroenteric and 5 (5 per cent) enterocolic. Only 12 of 103 intussusceptions (12 per cent) in 12 of 75 (16 per cent) patients required surgical therapy and were considered to be complicated, with half of these having a neoplastic lead point. Length (P < 0.001), diameter (P< 0.001) and type (P = 0.002) of intussusception as well as presence of vessels (P = 0.023) within an intussusception on a CT scan, clinical symptoms (P = 0.007) and signs of bowel obstruction (P < 0.001) were associated with a surgical outcome. Conclusion: Clinical symptoms, signs of bowel obstruction, type and length of intussusception, and a visible tumour within an intussusception on CT scan were critical signs of complicated intussusception, requiring surgical intervention.

description:   
The properties of the ocean are of wide interest in numerous fields. Measurements of oceanic temperature are particularly important due to their impact on global climate. However, in order to measure water temperature below the ocean surface, only in situ methods are currently available, with corresponding limits on sampling frequency. Light Detection And Ranging (‘lidar’) methods provide a potential solution. Oceanographic lidar systems use short pulses of light to interrogate the properties of the water column. Prior systems have used elastically-scattered light for applications including the measurement of turbidity, chlorophyll and fisheries, but it is also possible to use light which has undergone wavelength change via the inelastic process of Raman scattering. By measuring the polarisation and spectrum of Raman-scattered light, subsurface water temperature can be inferred from lidar returns. However, the best approach for a Raman lidar system is still unclear.
This work uses simulations to compare and assess the performance of several different approaches to temperature measurement with Raman lidar. This was accomplished by modifying an existing unpolarised Monte Carlo simulation to simulate polarised scattering and detection.
Two temperature measurement methods were studied. Methods involving the measurement of depolarisation were found to perform comparatively poorly: for good results, they required very small fields of view and clearest oceanic waters, and even then encountered problems due to multiple scattering. By contrast, methods using the ratio of Raman spectral bands performed much better, and allowed the development of a simple inversion algorithm to recover temperature from lidar returns. This will inform the design of future Raman lidar systems for temperature measurement.

description: Simple Summary There continues to be little research in the literature on perioperative outcomes after cytoreductive surgery (CRS) combined with intraoperative hyperthermic chemotherapy-lavage (HITOC) in patients with malignant pleural tumours. The aim of this multicentre study was to assess the results of the current practice in Germany so as to give recommendations to standardize the procedure. CRS with cisplatin-based HITOC can be performed with low major morbidity and a low rate of renal insufficiency, which was associated with the cisplatin dosage of irrigation. In the context of quality assurance, the objectives were to describe the surgical treatment and postoperative morbidity (particularly renal insufficiency). A retrospective, multicentre study of patients who underwent cytoreductive surgery (CRS) with cisplatin-based HITOC was performed. The study was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation (GZ: RI 2905/3-1)). Patients (n = 350) with malignant pleural mesothelioma (n = 261; 75%) and thymic tumours with pleural spread (n = 58; 17%) or pleural metastases (n = 31; 9%) were analyzed. CRS was accomplished by pleurectomy/decortication (P/D: n = 77; 22%), extended P/D (eP/D: n = 263; 75%) or extrapleural pneumonectomy (EPP: n = 10; 3%). Patients received cisplatin alone (n = 212; 61%) or cisplatin plus doxorubicin (n = 138; 39%). Low-dose cisplatin (<= 125 mg/m(2) BSA) was given in 67% of patients (n = 234), and high-dose cisplatin (>125 mg/m(2) BSA) was given in 33% of patients (n = 116). Postoperative renal insufficiency appeared in 12% of the patients (n = 41), and 1.4% (n = 5) required temporary dialysis. Surgical revision was necessary in 51 patients (15%). In-hospital mortality was 3.7% (n = 13). Patients receiving high-dose cisplatin were 2.7 times more likely to suffer from renal insufficiency than patients receiving low-dose cisplatin (p = 0.006). The risk for postoperative renal failure is dependent on the intrathoracic cisplatin dosage but was within an acceptable range.

Taxonomy

description: Description of Cossulus Staudinger, 1887
Medium sized, color of wings from white to dark grey and brown. Antenna structure various (from complete splitting of comb processes to almost complete fusion of notch and even reduction of comb processes). Apex of fore wing rounded, fore wing with characteristic reticulated pattern and alternation of paler and darker elements. Hind wing without pattern.
Male genitalia. Uncus wide with rounded apex; gnathos arms long, thick; medial part of gnathos round, densely covered with small spikes. Valva lanceolately narrowing in distal part, more or less expressed crest (often with uneven edge) on dorsal edge; distal edge membranous; sclerotized and membranous parts of valva with fuzzy border. Transtilla processes uncinately bent, tapered with wide base. Juxta saddle-like with two long lateral processes. Saccus small, rounded. Phallus poorly sclerotized, distal aperture in dorso-apical position, in length from one-third to one-half of phallus.
Female genitalia. Papillae anales rounded on apices, relatively long. Posterior apophyses two times longer than anterior ones. Ostium slit-shaped, immersed; ductus of medium length, bursa copulatrix sack-like, without signa. Ductus seminalis extends from ductus near its confluence into bursa.
Adult flight period from April to October. The altitude where species of Cossulus occur ranges from 400 (in the Karakum Desert) to 3500 m (in Afghanistan). It is possible that species of this genus are univoltine. No data on the morphology and host plants of caterpillars are available.
Diagnosis. Cossulus differs from the other genera of Cossulinae by the specific shape of antenna (from complete splitting of comb processes to almost complete fusion of notch and even reduction of comb processes).

description: Infection with the hepatitis E virus (HEV) is one of the main ubiquitous causes for developing an acute hepatitis. Moreover, chronification plays a predominant role in immunocompromised patients such as transplant recipients with more frequent severe courses. Unfortunately, besides reduction of immunosuppression and off-label use of ribavirin or pegylated interferon alfa, there is currently no specific anti-viral treatment to prevent disease progression. So far, research on involved immune mechanisms induced by HEV is limited. It is very difficult to collect clinical samples especially from the early phase of infection since this is often asymptomatic. Nevertheless, it is certain that the outcome of HEV-infected patients correlates with the strength of the proceeding immune response. Several lymphoid cells have been identified in contributing either to disease progression or achieving sustained virologic response. In particular, a sufficient immune control by both CD4(+) and CD8(+) T cells is necessary to prevent chronic viral replication. Especially the mechanisms underlying fulminant courses are poorly understood. However, liver biopsies indicate the involvement of cytotoxic T cells in liver damage. In this review, we aimed to highlight different parts of the lymphoid immune response against HEV and point out questions that remain unanswered regarding this underestimated global threat.

description: Understanding the physical and chemical processes at the interface of metals and topological insulators is crucial for developing the next generation of topological quantum devices. Here we report the discovery of robust superconductivity in Pd/Bi$_2$Se$_3$ bilayers fabricated by sputtering Pd on the surface of Bi$_2$Se$_3$. Through transmission electron microscopy measurements, we identify that the observed interfacial superconductivity originates from the diffusion of Pd into Bi$_2$Se$_3$. In the diffusion region, Pd chemically reacts with Bi$_2$Se$_3$ and forms a layer of PdBiSe, a known su-perconductor with a bulk transition temperature of 1.5 K. Our work provides a method for in-troducing superconductivity into Bi$_2$Se$_3$, laying the foundation for developing sophisticated Bi$_2$Se$_3$-based topological devices.
