ABSTRACT
AIM: Appendiceal neoplasms are rare subtypes of colorectal tumours that mainly affect younger patients some 20 years earlier than other colon tumours. The aim of this study was to gain more insight into the histological subtypes of this rare disease and include cases previously excluded, such as mucinous neoplasia. METHOD: The cohort study included 1097 patients from the Munich Cancer Registry (MCR) diagnosed between 1998 and 2020. Joinpoint analysis was used to determine trend in incidence. Baseline demographic comparisons and survival analyses using competing risk and univariate/multivariate methods were conducted according to tumour histology: adenocarcinoma (ADENO), neuroendocrine neoplasia (NEN), mixed adeno-neuroendocrine carcinoma (MANEC), and low- (LAMN) and high-grade mucinous neoplasia (HAMN). RESULTS: Up to 2016 the number of cases increased significantly [annual per cent change (APC) = 6.86, p < 0.001] followed by a decline in the following years (APC = -14.82, p = 0.014; average APC = 2.5, p = 0.046). Comparison of all patients showed that NEN (48.4%) and mucinous neoplasms (11.6%) had a considerably better prognosis than ADENO (36.0%) and MANEC (3.0%, p < 0.0001). A multivariate analysis within the NEN and ADENO subgroups revealed that further histological classification was not prognostically relevant, while older age and regional tumour spread at diagnosis were associated with a poor prognosis. ADENO histology with high tumour grade and appendectomy only was also associated with poorer survival. CONCLUSION: Appendiceal neoplasms are histologically heterogeneous; however, this diversity becomes less relevant compared with the marked difference from cancers of the remaining colon. The previously observed increase in cases appears to be abating; fewer cases of appendicitis and/or appendectomies or changes in histopathological assessment may be behind this trend.

The aim of the present study was to investigate whether grey matter (GM) reductions in acute anorexia nervosa (AN) are (i) valid for adolescents (age 14-18 years), (ii) reversible following short-term psychotherapeutic and nutritional therapy and (iii) depend on psychological components like attachment trauma. 3T MRI including a high-resolution T1 MPRAGE was performed in 22 female adolescents in the acute state of AN (age: 15.2 ± 1.2 years) and after weight restoration (duration: 2.6 ± 1 months, n = 18) and compared with 18 gender-matched healthy controls. The Adult Attachment Projective Picture System was used to classify resolved and unresolved attachment patterns. GM decreases were localized in extensive cortical areas including the insula, prefrontal and cingulate cortices as well as subcortical regions during acute AN, which partially increased after therapy with a relative sparing of the hippocampus and parahippocampal gyrus. The resolved group showed more GM recovery in regions of the left hippocampus and parahippocampal gyrus, bilateral cerebellar regions, right precuneus and adjacent cingulate cortices relative to the unresolved pattern. Structural anomalies in adolescent AN that recovered after treatment may be primarily the consequence of malnutrition, whereas several regions did not display significant recovery. Attachment status seems to influence region-specific GM recovery.

ABSTRACT
The highly automated macromolecular crystallography beamline AMX/17-ID-1 is an undulator-based high-intensity (>5 × 1012â photonsâ s-1), micro-focus (7â µm × 5â µm), low-divergence (1â mrad × 0.35â mrad) energy-tunable (5-18â keV) beamline at the NSLS-II, Brookhaven National Laboratory, Upton, NY, USA. It is one of the three life science beamlines constructed by the NIH under the ABBIX project and it shares sector 17-ID with the FMX beamline, the frontier micro-focus macromolecular crystallography beamline. AMX saw first light in March 2016 and started general user operation in February 2017. At AMX, emphasis has been placed on high throughput, high capacity, and automation to enable data collection from the most challenging projects using an intense micro-focus beam. Here, the current state and capabilities of the beamline are reported, and the different macromolecular crystallography experiments that are routinely performed at AMX/17-ID-1 as well as some plans for the near future are presented.

The combination of the anti-PD-L1 antibody atezolizumab and the anti-VEGF bevacizumab is the first approved immunotherapeutic regimen for first-line therapy in patients with unresectable hepatocellular carcinoma (HCC), currently approved in more than 80 countries. The efficacy and tolerability of this regimen suggest that the use of atezolizumab + bevacizumab could be extended to the treatment of patients with intermediate-stage HCC in combination with transarterial chemoembolization (TACE). The authors describe the rationale and design of the DEMAND study. This investigator-initiated, multicenter, randomized phase II study is the first trial to evaluate the safety and efficacy of atezolizumab + bevacizumab prior to or in combination with TACE in patients with intermediate-stage HCC. The primary end point is the 24-month survival rate; secondary end points include objective response rate, progression-free survival, safety and quality of life. Clinical Trial Registration: NCT04224636 (ClinicalTrials.gov).

Perioperative chemotherapy with 5-fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) is a mainstay in the treatment of esophagogastric adenocarcinomas (EGA). Trastuzumab improved survival when added to chemotherapy in patients with HER-2-positive metastatic EGA. We investigated the combination of trastuzumab and FLOT as perioperative treatment in patients with locally advanced EGA. A multicenter phase II study evaluated the efficacy and toxicity of perioperative FLOT (24-hours 5-FU 2600 mg/m2 , leucovorin 200 mg/m2 , oxaliplatin 85 mg/mg2 , docetaxel 50 mg/m2 , trastuzumab 6 mg/kg then 4 mg/kg d1, repeated d15 for four cycles preoperatively and postoperatively followed by 9 cycles of trastuzumab monotherapy) in patients with HER-2 positive EGA. Patients had ≥cT2, any N, M0 EGA. The primary endpoint was the rate of centrally assessed pathological complete response (pCR). Secondary endpoints comprised disease-free (DFS) and overall survival (OS), R0 resection rate, toxicity and surgical morbidity. Fifty-six evaluable patients (median age 62 years) were included; n = 40 had tumors originating from the esophagogastric junction; T stage was (cT2/3/4/unknown): 4/42/8/2; n = 50 patients had cN+ disease. Main adverse events grades 3-4: leukopenia (17.9%), neutropenia (46.6%) and diarrhea (17.0%). All patients underwent tumor resections. R0 resection rate was 92.9%. Eight patients had anastomotic leakage. One postoperative death occurred. pCR was found in 12 patients (21.4%) and a further n = 14 patients (25.0%) had near complete response. Median DFS was 42.5 months and the 3-year OS rate was 82.1%. The primary endpoint of achieving a pCR >20% was reached. No unexpected safety issues were observed. Survival data are promising.

Here we present two robotic sample changers integrated into the experimental stations for the macromolecular crystallography (MX) beamlines AMX and FMX, and the biological small-angle scattering (bioSAXS) beamline LiX. They enable fully automated unattended data collection and remote access to the beamlines. The system designs incorporate high-throughput, versatility, high-capacity, resource sharing and robustness. All systems are centered around a six-axis industrial robotic arm coupled with a force torque sensor and in-house end effectors (grippers). They have the same software architecture and the facility standard EPICS-based BEAST alarm system. The MX system is compatible with SPINE bases and Unipucks. It comprises a liquid nitrogen dewar holding 384 samples (24 Unipucks) and a stay-cold gripper, and utilizes machine vision software to track the sample during operations and to calculate the final mount position on the goniometer. The bioSAXS system has an in-house engineered sample storage unit that can hold up to 360 samples (20 sample holders) which keeps samples at a user-set temperature (277â K to 300â K). The MX systems were deployed in early 2017 and the bioSAXS system in early 2019.

Two new macromolecular crystallography (MX) beamlines at the National Synchrotron Light Source II, FMX and AMX, opened for general user operation in February 2017 [Schneider et al. (2013). J. Phys. Conf. Ser. 425, 012003; Fuchs et al. (2014). J. Phys. Conf. Ser. 493, 012021; Fuchs et al. (2016). AIP Conf. Proc. SRI2015, 1741, 030006]. FMX, the micro-focusing Frontier MX beamline in sector 17-ID-2 at NSLS-II, covers a 5-30â keV photon energy range and delivers a flux of 4.0â ×â 1012â photonsâ s-1 at 1â Å into a 1â µmâ ×â 1.5â µm to 10â µmâ ×â 10â µm (Vâ ×â H) variable focus, expected to reach 5â ×â 1012â photonsâ s-1 at final storage-ring current. This flux density surpasses most MX beamlines by nearly two orders of magnitude. The high brightness and microbeam capability of FMX are focused on solving difficult crystallographic challenges. The beamline's flexible design supports a wide range of structure determination methods - serial crystallography on micrometre-sized crystals, raster optimization of diffraction from inhomogeneous crystals, high-resolution data collection from large-unit-cell crystals, room-temperature data collection for crystals that are difficult to freeze and for studying conformational dynamics, and fully automated data collection for sample-screening and ligand-binding studies. FMX's high dose rate reduces data collection times for applications like serial crystallography to minutes rather than hours. With associated sample lifetimes as short as a few milliseconds, new rapid sample-delivery methods have been implemented, such as an ultra-high-speed high-precision piezo scanner goniometer [Gao et al. (2018). J. Synchrotron Rad. 25, 1362-1370], new microcrystal-optimized micromesh well sample holders [Guo et al. (2018). IUCrJ, 5, 238-246] and highly viscous media injectors [Weierstall et al. (2014). Nat. Commun. 5, 3309]. The new beamline pushes the frontier of synchrotron crystallography and enables users to determine structures from difficult-to-crystallize targets like membrane proteins, using previously intractable crystals of a few micrometres in size, and to obtain quality structures from irregular larger crystals.

INTRODUCTION: Endoscopic full-thickness resection (eFTR) using the full-thickness resection device (FTRD®) is a novel minimally invasive procedure that allows the resection of various lesions in the gastrointestinal tract including the colorectum. Real-world data outside of published studies are limited. The aim of this study was a detailed analysis of the outcomes of colonoscopic eFTR in different hospitals from different care levels in correlation with the number of endoscopists performing eFTR. MATERIAL AND METHODS: In this case series, the data of all patients who underwent eFTR between November 2014 and June 2019 (performed by a total of 22 endoscopists) in 7 hospitals were analyzed retrospectively regarding rates of technical success, R0 resection, and procedure-related complications. RESULTS: Colonoscopic eFTR was performed in 229 patients (64.6% men; average age 69.3 ± 10.3 years) mainly on the basis of the following indication: 69.9% difficult adenomas, 21.0% gastrointestinal adenocarcinomas, and 7.9% subepithelial tumors. The average size of the lesions was 16.3 mm. Technical success rate of eFTR was achieved in 83.8% (binominal confidence interval 78.4-88.4%). Overall, histologically complete resection (R0) was achieved in 77.2% (CI 69.8-83.6%) while histologically proven full-wall excidate was confirmed in 90.0% (CI 85.1-93.7%). Of the resectates obtained (n = 210), 190 were resected en bloc (90.5%). We did not observe a clear improvement of technical success and R0 resection rate over time by the performing endoscopists. Altogether, procedure-related complications were observed in 17.5% (mostly moderate) including 2 cases of acute gangrenous appendicitis requiring operation. DISCUSSION: In this pooled analysis, eFTR represents a feasible, effective, and safe minimally invasive endoscopic technique.

This study examined how non-suicidal self-injury disorder (NSSID) differs with respect to mental disorders, gender and attachment status in adolescent psychiatric patients. In particular, we analyzed attachment-related traumatic material underlying adolescent NSSID. Our sample consisted of 137 in-patient adolescents aged 12 to 18 years (73% female, Mage = 15.09, SD = 1.44; 27% male, Mage = 14.65, SD = 1.53). Forty-four patients (32.1%) fulfilled the diagnostic criteria for NSSID according to the DSM-5 and ninety-three patients (67.9%) did not meet diagnostic criteria for NSSID. Our results revealed a higher prevalence of NSSID in female patients and in patients with mood disorders. In the total sample, 52% of our in-patients were classified with an unresolved attachment status. The diagnostic subgroup analysis demonstrated a higher percentage of unresolved attachment status only in patients with eating disorders and NSSID. However, our in-depth analysis of the total sample revealed that patients with NSSID demonstrated more traumatic material in their attachment interviews indicating a greater severity of attachment trauma. In particular the theme of helplessness in interpersonal conflicts left them in a state of attachment dysregulation. Intervention strategies targeting traumatic attachment-related themes might be useful to reduce the number of adolescents engaging in NSSI.

OBJECTIVE: Hepatocellular carcinoma (HCC) is a major cause of death worldwide and its incidence is expected to increase globally. Aim of this study was to assess whether the implementation of screening policies and the improvement of treatment options translated into a real-world survival benefit in HCC patients. DESIGN: 4078 patients diagnosed with HCC between 1998 and 2016 from the Munich Cancer Registry were analysed. Tumour characteristics and outcome were analysed by time period and according to age and presence of metastases at diagnosis. Overall survival (OS) was analysed using Kaplan-Meier method and relative survival (RS) was computed for cancer-specific survival. Cox proportional hazard models were conducted to control for prognostic variables. RESULTS: While incidence of HCC remained substantially stable, tumours were diagnosed at increasingly earlier stages, although the median age at diagnosis increased. The 3 years RS in HCC improved from 19.8% in 1998-2002, 22.4% in 2003-2007, 30.6% in 2008-2012 up to 31.0% in 2013-2016. Median OS increased from 6 months in 1998-2002 to 12 months in 2008-2016. However, analysis according to the metastatic status showed that survival improved only in patients without metastases at diagnosis whereas the prognosis of patients with metastatic disease remained unchanged. CONCLUSION: These real-world data show that, in contrast to the current assumptions, the incidence of HCC did not increase in a representative German region. Earlier diagnosis, likely related to the implementation of screening programmes, translated into an increasing employment of effective therapeutic options and a clear survival benefit in patients without metastases at diagnosis, irrespective of age.

Optical sensors developed for the assessment of oxygen in tissue microvasculature, such as those based on near-infrared spectroscopy, are limited in application by light scattering. Optoacoustic methods are insensitive to light scattering, and therefore, they can provide higher specificity and accuracy when quantifying local vascular oxygenation. However, currently, to the best of our knowledge, there is no low-cost, single point, optoacoustic sensor for the dedicated measurement of oxygen saturation in tissue microvasculature. This work introduces a spectroscopic optoacoustic sensor (SPOAS) for the non-invasive measurement of local vascular oxygenation in real time. SPOAS employs continuous wave laser diodes and measures at a single point, which makes it low-cost and portable. The SPOAS performance was benchmarked using blood phantoms, and it showed excellent linear correlation (R2=0.98) with a blood gas analyzer. Subsequent measurements of local vascular oxygenation in living mice during an oxygen stress test correlated well with simultaneous readings from a reference instrument.

BACKGROUND: Gemcitabine/erlotinib treatment offers limited benefit in unselected patients with pancreatic ductal adenocarcinoma (PDAC). Development of skin rash has been associated with favorable outcomes in patients treated with gemcitabine/erlotinib. This study aimed to extend knowledge on the effectiveness of gemcitabine/erlotinib in metastatic PDAC in the context of clinical practice and with focus on skin rash. METHODS: This multicenter, non-interventional study enrolled 376 patients with metastatic PDAC receiving gemcitabine/erlotinib. The primary endpoint was overall survival (OS) in patients with skin rash versus no skin rash. Secondary endpoints included progression-free survival (PFS), treatment satisfaction and safety. All data were analyzed using descriptive statistics. Survival time and time to disease progression were estimated using the Kaplan-Meier method. Effectiveness endpoints were analyzed for subgroups by skin rash grade (no rash, rash grade 1, rash grade ≥ 2), duration of erlotinib treatment (≤8 weeks, > 8 weeks), Eastern Cooperative Oncology Group (ECOG) performance status at baseline (0-1, 2) and age (≤65 years, > 65 years). RESULTS: Within the full analysis set (FAS; N = 270), 48 patients (17.8%) developed grade 1 rash, 51 patients (18.9%) grade ≥ 2 rash, while 171 patients (63.3%) did not develop a rash. Median OS of all patients was 9.11 months with an OS of 9.93 months in rash-positive and 8.68 months in rash-negative patients. Median PFS was 5.06 months for rash-positive and 4.11 months for rash-negative patients. PFS was longer in patients with rash grade ≥ 2 and in older patients (> 65 years). Examination using a multivariate Cox proportional model revealed that an age > 65 years was associated with longer OS (hazard ratio 0.640; p = 0.0327) and PFS (hazard ratio 0.642; p = 0.0026). Out of the 338 patients in the SAF, 310 patients (91.7%) experienced at least one AE, and 176 patients (52.1%) experienced skin-related side effects, all of which were CTC grade 1 to 3. CONCLUSIONS: Comparing rash-positive with rash-negative patients showed no significant difference in survival. While patients with rash grade ≥ 2 and older patients (independent of skin reactions) showed longer PFS, this did not translate into prolonged OS. The study did not reveal new safety signals.

BACKGROUND: As of 13 July 2020, 12.9 million COVID-19 cases have been reported worldwide. Prior studies have demonstrated that local socioeconomic and built environment characteristics may significantly contribute to viral transmission and incidence rates, thereby accounting for some of the spatial variation observed. Due to uncertainties, non-linearities, and multiple interaction effects observed in the associations between COVID-19 incidence and socioeconomic, infrastructural, and built environment characteristics, we present a structured multimethod approach for analysing cross-sectional incidence data within in an Exploratory Spatial Data Analysis (ESDA) framework at the NUTS3 (county) scale. METHODS: By sequentially conducting a geospatial analysis, an heuristic geographical interpretation, a Bayesian machine learning analysis, and parameterising a Generalised Additive Model (GAM), we assessed associations between incidence rates and 368 independent variables describing geographical patterns, socioeconomic risk factors, infrastructure, and features of the build environment. A spatial trend analysis and Local Indicators of Spatial Autocorrelation were used to characterise the geography of age-adjusted COVID-19 incidence rates across Germany, followed by iterative modelling using Bayesian Additive Regression Trees (BART) to identify and measure candidate explanatory variables. Partial dependence plots were derived to quantify and contextualise BART model results, followed by the parameterisation of a GAM to assess correlations. RESULTS: A strong south-to-north gradient of COVID-19 incidence was identified, facilitating an empirical classification of the study area into two epidemic subregions. All preliminary and final models indicated that location, densities of the built environment, and socioeconomic variables were important predictors of incidence rates in Germany. The top ten predictor variables' partial dependence exhibited multiple non-linearities in the relationships between key predictor variables and COVID-19 incidence rates. The BART, partial dependence, and GAM results indicate that the strongest predictors of COVID-19 incidence at the county scale were related to community interconnectedness, geographical location, transportation infrastructure, and labour market structure. CONCLUSIONS: The multimethod ESDA approach provided unique insights into spatial and aspatial non-stationarities of COVID-19 incidence in Germany. BART and GAM modelling indicated that geographical configuration, built environment densities, socioeconomic characteristics, and infrastructure all exhibit associations with COVID-19 incidence in Germany when assessed at the county scale. The results suggest that measures to implement social distancing and reduce unnecessary travel may be important methods for reducing contagion, and the authors call for further research to investigate the observed associations to inform prevention and control policy.

TransIdentity - Identity Development Among Adolescent Trans*people Identity development is one of the most important developmental tasks of adolescence. Adolescents whose gender identity does not correspond to the gender assigned at birth (trangender people) are also faced with this challenge, as are cis-gender adolescents of the same age. This study is the first to examine the personality function of identity in transgender adolescents. Based on the self report of a population of 69 adolescents from the outpatient unit for gender dysphoria the extent of identity diffusion measured by AIDA (Assessment of Identity Development in Adolescence) was compared with the values of the normative sample consisting of German-speaking pupils. Both the overall construct of identity diffusion and the areas of continuity and coherence showed average values in the examined young people, which speaks against pathological identity development. Nevertheless, identity diffusion was found in over a third (36 %). Most notably the aspect of stabilising relationships and roles was above average, which suggests that positive role identification from the areas of culture, family and body-self is present to a lesser extent than in the norm sample. The identity-stabilizing feeling of social anchoring appears to be impaired in the young transidents studied.

Therapeutic Models for Children and Adolescents with Gender Dysphoria: Overview with Focus on Austrian Treatment Reality Young people whose experienced gender differs from their aligned sex are increasingly visible in public life as well as in the medical care system. For those children and adolescents, who can experience a high degree of suffering because of the discrepancy between aligned sex and desired gender, treatment guidelines have been developed. In this short narrative review, classification options, epidemiological data, health-care data and treatment guidelines are presented with an emphasis on the Austrian health care system.

Multiple Substance Abuse as a Form of High Risk Behavior in Adolescence We identify multiple substance abuse as a form of high risk behavior in adolescence based on a sample of in-patient adolescents. 43 adolescents were treated for substance abuse over the course of 20 months. 70 % reported the use of three or more different drugs, with an average of 5,35 consumed substances. The most commonly abused substance was cannabis, followed by synthetic drugs such as cocaine or ecstasy. We observed a high rate of non-suicidal self-injury as a comorbidity of multiple substance abuse in our sample. 73,3 % of adolescents with high risk, multiple substance abuse fulfilled diagnostic criteria for non-suicidal self-injury.

Advances in synchrotron technology are changing the landscape of macromolecular crystallography. The two recently opened beamlines at NSLS-II-AMX and FMX-deliver high-flux microfocus beams that open new possibilities for crystallographic data collection. They are equipped with state-of-the-art experimental stations and automation to allow data collection on previously intractable crystals. Optimized data collection strategies allow users to tailor crystal positioning to optimally distribute the X-ray dose over its volume. Vector data collection allows the user to define a linear trajectory along a well diffracting volume of the crystal and perform rotational data collection while moving along the vector. This is particularly well suited to long, thin crystals. We describe vector data collection of three proteins-Akt1, PI3Kα, and CDP-Chase-to demonstrate its application and utility. For smaller crystals, we describe two methods for multicrystal data collection in a single loop, either manually selecting multiple centers (using H108A-PHM as an example), or "raster-collect", a more automated approach for a larger number of crystals (using CDP-Chase as an example).

Prevalence and characteristics of peer victimisation in adolescent psychiatric inpatients Abstract. Objective: Repeated and long-lasting victimisation, as defined by bullying, represents a wide spread health hazard. The aim of the present study was to present the prevalence of bullying in adolescent psychiatric inpatients. We analysed relations between bullying and sociodemographic and psychopathological variables. Furthermore, we investigated the number and nature of bullies, feasible resources, and parental perception on bullying in adolescence. Method: In total, 128 adolescent inpatients were surveyed with a bullying questionnaire and youth self-report. In addition, their clinical symptomatology was investigated. Results: Bullying affected one third of our sample. Male and female victims showed significantly more internal problems. Girls in addition revealed more external behaviour problems. Unlike non-suicidal, self-harming behaviour, suicidal ideation and suicidal behaviour occurred significantly more in patients with bullying experience. Conclusion: A significant number of adolescent in our sample experienced bullying and associated psychological strains. This should especially be considered in child and adolescent anamnesis.

BACKGROUND: Galunisertib is the first-in-class, first-in-human, oral small-molecule type I transforming growth factor-beta receptor (ALK5) serine/threonine kinase inhibitor to enter clinical development. The effect of galunisertib vs. placebo in patients with unresectable pancreatic cancer was determined. METHODS: This was a two-part, multinational study: phase 1b was a non-randomised, open-label, multicentre, and dose-escalation study; phase 2 was a randomised, placebo- and Bayesian-augmented controlled, double-blind study in patients with locally advanced or metastatic pancreatic adenocarcinoma considered candidates for first-line chemotherapy with gemcitabine. Patients were randomised 2:1 to galunisertib-gemcitabine (N = 104) or placebo-gemcitabine (N = 52). Gemcitabine dose was 1000 mg/m2 QW. Primary endpoints for phases 1b and 2, respectively, were phase 2 dose and overall survival. Secondary objectives included tolerability and biomarkers. RESULTS: Dose-escalation suggested a 300-mg/day dose. Primary objective was met: median survival times were 8.9 and 7.1 months for galunisertib and placebo, respectively (hazard ratio [HR] = 0.79 [95% credible interval: 0.59-1.09] and posterior probability HR < 1 = 0.93). Lower baseline biomarkers macrophage inflammatory protein-1-alpha and interferon-gamma-induced protein 10 were associated with galunisertib benefit. CONCLUSIONS: Galunisertib-gemcitabine combination improved overall survival vs. gemcitabine in patients with unresectable pancreatic cancer, with minimal added toxicity. Future exploration of galunisertib in pancreatic cancer is ongoing in combination with durvalumab.
