Abstract
BACKGROUND G-EPOSS is a prospective, non-interventional, German multicentre study of patients with moderate-to-severe plaque psoriasis receiving guselkumab, a therapeutic monoclonal antibody targeting interleukin-23, in a real-world setting. OBJECTIVES The objective of the study was to evaluate the effectiveness and safety of guselkumab, including its impact on skin, health-related quality of life (HRQoL), sexuality, and perceived stigmatization. METHODS Patients (≥18 years old) received guselkumab per routine clinical practice. The primary endpoint was the proportion of patients achieving absolute Psoriasis Area and Severity Index (PASI) ≤ 3 at Week (W)28. Secondary endpoint assessments over 28 weeks included the Nail Psoriasis Severity Index (NAPSI), anogenital Physician's Global Assessment (aPGA), and Dermatology Life Quality Index (DLQI). Sexuality and perceived stigmatization were assessed by patients using the Relationship and Sexuality Scale (RSS) and Perceived Stigmatization Questionnaire (PSQ), respectively. RESULTS Overall, 293 patients were included in the evaluable set population. Mean age and disease duration were 45.6 and 17.6 years, respectively. At baseline, mean PASI, aPGA and DLQI scores were 15.3, 2.7 and 11.3, respectively. In total, 25.9% of patients had received a prior biologic. Overall, 83.0% of patients achieved PASI ≤ 3, and 56.2%/35.1% achieved PASI ≤ 1/PASI = 0, respectively, at W28. Among those with NAPSI ≥ 1 and aPGA ≥ 1 at baseline, NAPSI = 0 and aPGA = 0 were achieved by 39.2% and 61.1% of patients, respectively, and 61.4% of patients achieved DLQI 0-1 at W28. Improvements were observed over 28 weeks across individual items of the DLQI, RSS and PSQ, indicating improved HRQoL and sex life, and decreased perceived stigmatization. Based on DLQI Question (Q)9, 53.6% of patients experienced sexual difficulties at baseline, which decreased to 12.1% at W28. DLQI Q9 responses were consistent with RSS item responses, highlighting DLQI Q9 as a sentinel for sexual impairment. CONCLUSIONS Guselkumab improved overall skin symptoms and HRQoL in patients with psoriasis and decreased sexual impairment and perceived stigmatization. No new safety signals were observed.

Abstract
BACKGROUND Ovarian cancer remains the deadliest of the gynecologic cancers in the United States. There have been limited advances in treatment strategies that have seen marked increases in overall survival. Thus, it is essential to continue developing and validating new treatment strategies and markers to identify patients who would benefit from the new strategy. In this report, we sought to further validate applications for a novel humanized anti-Sialyl Tn antibody-drug conjugate (anti-STn-ADC) in ovarian cancer. METHODS We aimed to further test a humanized anti-STn-ADC in sialyl-Tn (STn) positive and negative ovarian cancer cell line, patient-derived organoid (PDO), and patient-derived xenograft (PDX) models. Furthermore, we sought to determine whether serum STn levels would reflect STn positivity in the tumor samples enabling us to identify patients that an anti-STn-ADC strategy would best serve. We developed a custom ELISA with high specificity and sensitivity, that was used to assess whether circulating STn levels would correlate with stage, progression-free survival, overall survival, and its value in augmenting CA-125 as a diagnostic. Lastly, we assessed whether the serum levels reflected what was observed via immunohistochemical analysis in a subset of tumor samples. RESULTS Our in vitro experiments further define the specificity of the anti-STn-ADC. The ovarian cancer PDO, and PDX models provide additional support for an anti-STn-ADC-based strategy for targeting ovarian cancer. The custom serum ELISA was informative in potential triaging of patients with elevated levels of STn. However, it was not sensitive enough to add value to existing CA-125 levels for a diagnostic. While the ELISA identified non-serous ovarian tumors with low CA-125 levels, the sample numbers were too small to provide any confidence the STn ELISA would meaningfully add to CA-125 for diagnosis. CONCLUSIONS Our preclinical data support the concept that an anti-STn-ADC may be a viable option for treating patients with elevated STn levels. Moreover, our STn-based ELISA could complement IHC in identifying patients with whom an anti-STn-based strategy might be more effective.

Abstract
We report on the direct search for cosmic relic neutrinos using data acquired during the first two science campaigns of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity molecular tritium gas source are analyzed by a high-resolution MAC-E filter around the end point at 18.57 keV. The analysis is sensitive to a local relic neutrino overdensity ratio of η<9.7×10^{10}/α (1.1×10^{11}/α) at a 90% (95%) confidence level with α=1 (0.5) for Majorana (Dirac) neutrinos. A fit of the integrated electron spectrum over a narrow interval around the end point accounting for relic neutrino captures in the tritium source reveals no significant overdensity. This work improves the results obtained by the previous neutrino mass experiments at Los Alamos and Troitsk. We furthermore update the projected final sensitivity of the KATRIN experiment to η<1×10^{10}/α at 90% confidence level, by relying on updated operational conditions.

Abstract
We report on the light sterile neutrino search from the first four-week science run of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are analyzed by a high-resolution MAC-E filter down to 40 eV below the endpoint at 18.57 keV. We consider the framework with three active neutrinos and one sterile neutrino. The analysis is sensitive to the mass, m_{4}, of the fourth mass state for m_{4}^{2}≲1000 eV^{2} and to active-to-sterile neutrino mixing down to |U_{e4}|^{2}≳2×10^{-2}. No significant spectral distortion is observed and exclusion bounds on the sterile mass and mixing are reported. These new limits supersede the Mainz results for m_{4}^{2}≲1000 eV^{2} and improve the Troitsk bound for m_{4}^{2}<30 eV^{2}. The reactor and gallium anomalies are constrained for 100<Δm_{41}^{2}<1000 eV^{2}.

Abstract
We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from a high-purity gaseous molecular tritium source are energy analyzed by a high-resolution MAC-E filter. A fit of the integrated electron spectrum over a narrow interval around the kinematic end point at 18.57 keV gives an effective neutrino mass square value of (-1.0_{-1.1}^{+0.9}) eV^{2}. From this, we derive an upper limit of 1.1 eV (90% confidence level) on the absolute mass scale of neutrinos. This value coincides with the KATRIN sensitivity. It improves upon previous mass limits from kinematic measurements by almost a factor of 2 and provides model-independent input to cosmological studies of structure formation.

Abstract
Abstract
Sialyl-Thomsen-nouveau antigen (STn), a tumor-associated carbohydrate antigen (TACA) is elevated in several solid tumors. In ovarian cancer, increased STn levels correlate with chemo-resistance and decreased suvival. Our recent studies suggest that many of STn antibodies utilized previously were not as specific as originally proposed so through a proprietary platform, a highly specific anti-STn antibody with high binding affinity was developed. Subsequent study of this antibody as an antibody-drug conjugate (ADC) demonstrated reduced tumor growth in patient derived xenograft models of high grade serous OvCa, an effect that positively correlated with tumor STn levels. Collectively, these findings and those by others suggest that STn might serve as relevant OvCa therapeutic target and could play a role as a biomarker for discriminating malignant from benign ovarian tumors. In this investigation, we designed and optimized a custom ELISA to detect STn levels in human serum. Our objective was to determine whether we could distinguish between benign and malignant serum samples. The assay was employed on retrospective serum samples derived from patients diagnosed with benign gynecologic disease (n =62) and serum from patients diagnosed with high grade OvCa (n =200). Serum samples were all collected from consented patients under an approved IRB protocol. Based on our analysis, we determined the areas under the receiver operating characteristic curves (AUC of ROC) to compare how STn values associated with malignant or benign conditions. Our STn assay demonstrated an AUC of 0.74 at an STn value of 0.025. Of the 8 patients with malignancy and a CA-125 < 35 mIU/ml, 6 were found to have elevated STn above the cutoff value and thus the sensitivity of CA-125 was significantly improved if elevated levels of STn were integrated as a biomarker. To determine whether circulating STn levels mirrored that which is detected in the tumor, we identified 15 samples with high (STn>0.096) and 15 samples with low (<0.096) levels and assessed STn in their matching formalin fixed, paraffin embedded tumor by immunohistochemistry (IHC). Elevated serum STn corresponded with positive STn focal 2+, 3+ staining 60% of the time while tumors with corresponding serum STn levels that were <0.096 were associated with 6.7% IHC tumor low focal 0, 1+ staining) STn staining. There was staining in tumor samples of patients that had relatively low STn levels in the serum, which is not surprising since not all STn glycosylated proteins are shed into the blood. These data suggest that serum STn levels may improve the sensitivity of CA-125 alone to detect malignancy in an adnexal mass of unknown nature making it a valuable biomarker for clinical triage. Additionally, serum STn levels have a significant correlation (Fisher exact p<0.01) with tumor expression and therefore may be useful in identifying women likely to respond to STn targeted agents.

Abstract
BACKGROUND In the recent years clinical ethics consultations (CEC) received an increasing attention not only in patients with medical conditions but also in those with mental disorders. However, the systematic and empirical knowledge is still small. The aim of this observational study was to investigate whether CECs differ between psychiatric and medical hospital inpatients regarding ethical issues, goals, characteristics, processes, and outcomes. METHODS This is a retrospective and in parts prospective analysis of a semi-structured CEC approach provided by the CEC service at a large German general hospital between January 2006 and June 2015. RESULTS A total of 259 CECs in three inpatient settings were investigated, i.e. intensive care units (ICU, 43.6%), low care units (LCU, 33.6%), and psychiatric care units (PCU, 22.8%). In all groups, most ethical issues addressed treatment intensity (80.6%) and resulted in over 93% in participants' agreement on final ethical recommendations as well as in high implementation rates (>89%). However, we found significant group differences: In PCUs patients participated more often in the CEC (p < .001), the number of all participants was higher (p < .001), CECs were more time expensive (p < .001), and more recommendations focused on interventions against the patients' declared intention (37.7% versus 0%) than in the other groups. DISCUSSION In spite of different clinical characteristics and ethical issues between patients and settings, consensus and implementation of the CEC recommendation could be achieved at a high rate in all groups. There are substantial differences regarding goals, participation of patients, and processes. It is worth considering adapting the CEC to the special needs in psychiatric settings, especially under the aspect of the patients' perspective and involvement.

Abstract
Ovarian cancer is the leading cause of death from gynecologic malignancies in the U.S. The current standard of care is tumor debulking followed by chemotherapy. This treatment results in approximately 70% of patients achieving an initial complete clinical response. However, many of these patients will unfortunately relapse with chemoresistant disease developing in part to the presence of cancer stem cells (CSCs) within the tumor. Indeed, ovarian CSCs have been identified and shown to be resistant to chemo- and radiotherapy. Cancer cell surface glycans, called tumor-associated carbohydrate antigens (TACAs), are a class of attractive cancer-specific targets found on the cell surface of many solid tumors. Siamab is targeting a glycan structure (Sialyl-Tn, STn) that is cancer-specific and a major reported constituent of two well-known CSC biomarkers, CD44 and MUC1, residing on both CSCs and mature malignant cells in some cancer types. Although CD44 and MUC1 are also present on normal tissue and normal stem cell surfaces, tumor and CSC specificity is conferred the presence of STn-glycosylated variants of these CSC markers and other cell surface proteins that are essentially absent from normal human tissues. Importantly, STn can be a component of CA-125 (MUC16), conferring additional specificity to this diagnostic marker for ovarian carcinoma. The elevated presence of STn in tumors is associated with metastatic disease, poor prognosis, and reduced overall survival. In addition, elevations in STn expression are linked to chemotherapy resistance and enable tumors to evade the host immune system. We have observed that STn levels are elevated in cancer cells following chemotherapy treatment in both in vitro and in vivo model systems and STn is present on specific subtype of tumor-infiltrating myeloid-derived suppressor cells. Both observations support the role of STn in tumor chemoresistance and immunomodulation. While attempts have been made to target STn clinically with a cancer vaccine, efficacy has been limited. Siamab has developed a unique immunotherapeutic solution aimed at eradicating human neoplasias by targeting both CSCs and bulk tumor to enable whole tumor killing. We have identified and humanized a panel of mouse monoclonal novel antibodies (Abs) that specifically target with high affinity the STn glycan independent of its carrier protein. These Abs are highly selective in binding assays demonstrating robust nanomolar EC50s, possess specificity on tissues as determined with neuraminidase treatment, and exhibit STn-specific glycan binding on Siamab’s proprietary glycan array. Antitumor efficacy was evaluated in vitro and in vivo utilizing humanized anti-STn antibody drug conjugated (ADC) material. Cell cytotoxicity was demonstrated in a panel of STn-expressing cell lines with low nanomolar IC50s. We confirmed that the decrease in proliferation in vitro can be translated to a reduction in tumor size in vivo, through a series of cell line and patient-derived ovarian cancer xenograft models. Inhibition of tumor progression were observed in all models, with complete regressions observed in some treatment arms. No significant weight loss was observed for any treatment groups, indicating the therapy was well tolerated by all the groups. A decrease in STn expression was noted in the tumors following treatment, indicating that we were hitting the target against which these Abs were generated. In addition, we have begun the development of both tissue- and serum-based biomarker assays utilizing these selective anti-STn Abs. Our data demonstrate that high-affinity, STn-selective humanized mAbs show promise as therapies for ovarian tumors, as well as tools for patient stratification and pharmacodynamic biomarker assessments.

Abstract
The expression of Sialyl-Tn (STn) in tumors is associated with metastatic disease, poor prognosis, and reduced overall survival. STn is expressed on ovarian cancer biomarkers including CA-125 (MUC16) and MUC1, and elevated serum levels of STn in ovarian cancer patients correlate with lower five-year survival rates. In the current study, we humanized novel anti-STn antibodies and demonstrated the retention of nanomolar (nM) target affinity while maintaining STn antigen selectivity. STn antibodies conjugated to Monomethyl Auristatin E (MMAE-ADCs) demonstrated in vitro cytotoxicity specific to STn-expressing ovarian cancer cell lines and tumor growth inhibition in vivo with both ovarian cancer cell line- and patient-derived xenograft models. We further validated the clinical potential of these STn-ADCs through tissue cross-reactivity and cynomolgus monkey toxicity studies. No membrane staining for STn was present in any organs of human or cynomolgus monkey origin, and the toxicity profile was favorable and only revealed MMAE-class associated events with none being attributed to the targeting of STn. The up-regulation of STn in ovarian carcinoma in combination with high affinity and STn-specific selectivity of the mAbs presented herein warrant further investigation for anti-STn antibody-drug conjugates in the clinical setting.

Abstract
Abstract
Introduction: Myeloid derived suppressor cells (MDSCs) are functionally defined by their capacity to suppress T cell immunity; therefore inhibiting these cells is of great interest for immuno-oncology applications. STn, the sialylated version of the carbohydrate Tn antigen, is broadly expressed in human cancers such as breast, ovarian, bladder, cervical, colon, and lung and is rarely expressed in normal adult human tissues. The presence of STn in tumors is associated with metastatic disease, poor prognosis, and reduced overall survival. Tumor STn expression is well established and can be leveraged for targeted cancer therapy, however its expression on immuno-suppressive tumor infiltrating lymphocytes such as MDSCs has not been established. Methods: We generated humanized anti-STn mAbs having no cross-reactivity to the asialylated form of STn (Tn) or other glycan antigens. The epitope targeted by these mAbs is the STn glycan itself, not a particular glycopeptide or carrier protein, which offers the broadest potential to bind to multiple STn-glycosylated proteins on cell surfaces. We used these mAbs to quantify specifically the expression of tumor and MDSC STn expression across a set of patient tumor samples. We further treated mice with a humanized anti-STn-MMAE antibody-drug conjugate to evaluate targeted depletion of STn+ MDSCs. In order to evaluate the therapeutic potential of targeting this MDSC phenotype, we further evaluated the immunosuppressive environment of tumors containing STn+ and STn- MDSCs. Results: For the first time, we report the detection of STn on the surface of MDSCs in a growing body of patient tumor samples. Our data in patients as well as xenograft models additionally links STn expression on MDSCs to tumor cell STn expression. We have also demonstrated depletion of STn+ MDSCs after treatment with an anti-STn antibody-drug conjugate in an ovarian carcinoma xenograft model. Conclusions: Our data demonstrated that STn provides a uniquely glycan-specific and potent target for treatment of solid tumors. Anti-STn therapeutics offer the potential to go beyond tumor targeting to also directly target and deplete immune-suppressive MDSCs, thus fostering immune re-engagement and increasing the potential for better patient outcomes.

Abstract
Recurrent ovarian cancer (OvCa) is thought to result in part from the inability to eliminate rare quiescent cancer stem cells (CSCs) that survive cytotoxic chemotherapy and drive tumor resurgence. The Sialyl-Thomsen-nouveau antigen (STn) is a carbohydrate moiety present on protein markers of CSCs in pancreatic, colon, and gastric malignancies. We have demonstrated that human OvCa cell lines contain varying levels of cells that independently express either STn or the ovarian CSC marker CD133. Here we determine co-expression of STn and CD133 in a subset of human OvCa cell lines. Analyses of colony and sphere forming capacity and of response to standard-of-care cytotoxic therapy suggest a subset of OvCa STn+ cells display some CSC features. The effect of the anti-STn antibody-drug conjugates (ADCs) S3F-CL-MMAE and 2G12-2B2-CL-MMAE on OvCa cell viability in vitro and in vivo was also assessed. Treatment with S3F-CL-MMAE reduced the viability of two of three OvCa cell lines in vitro and exposure to either S3F-CL-MMAE or 2G12-2B2-CL-MMAE reduced OVCAR3-derived xenograft volume in vivo, depleting STn+ tumor cells. In summary, STn+ cells demonstrate some stem-like properties and specific therapeutic targeting of STn in ovarian tumors may be an effective clinical strategy to eliminate both STn+ CSC and STn+ non-CSC populations.

Abstract
Abstract
Targeted therapeutics that can differentiate between normal and malignant tumor cells represent the ideal standard for the development of a successful anticancer strategy. The Sialyl-Thomsen-nouveau antigen (STn or Sialyl-Tn, also known as CD175s) is rarely observed in normal adult tissues, but it is abundantly expressed in many types of human epithelial cancers. Interestingly, we have observed that the level of this carbohydrate is elevated following chemotherapy treatment in both in vitro and in vivo model systems, suggesting a potential role of STn in chemoresistance. We have identified and humanized a panel of mouse monoclonal novel antibodies (Abs) that specifically target with high affinity the STn glycan independent of its carrier protein. We have demonstrated that these Abs are highly selective in binding assays demonstrating robust nanomolar EC50s, possess specificity on cancer tissues as determined with neuraminidase treatment, and exhibit STn-specific glycan binding on Siamab’s proprietary glycan array. Antitumor efficacy was evaluated in vitro and in vivo utilizing humanized anti-STn antibody-drug conjugated (ADC) material using MMAE as the cytotoxic agent. Cell cytotoxicity was demonstrated in a panel of STn-expressing cell lines with low nanomolar IC50s. In vivo, single-dose mouse PK studies were performed with humanized anti-STn ADCs and we determined half-life of approximately 3 days for both SIA01-ADC and SIA02-ADC. We confirmed that the decrease in proliferation in vitro can be translated to a reduction in tumor size in vivo through a series of cell line-derived and patient-derived (PDX) ovarian cancer and pancreatic cancer xenograft models. Inhibition of tumor progression was observed in all models with complete regressions observed in some treatment arms. No significant weight loss occurred in any treatment groups, indicating the therapy was well tolerated by all the groups. A decrease in STn expression was noted in the tumors following treatment, indicating that we were hitting the target against which these Abs were generated. In addition to these preclinical pharmacology studies, we demonstrated that the administration of our anti-STn ADC has an excellent safety profile through the completion of a non-GLP pilot PK/toxicity study in cynomolgus monkeys. No weight loss or deaths occurred in this study and no gross pathology changes were observed in all organs examined. Histopathologic changes were limited to the bone marrow with minimal to mild decreased cellularity and mild decrease in the myeloid to erythroid ratio observed. All clinical chemistry results (liver, kidney function, etc.) were normal throughout study. Changes in hematology parameters–modest neutropenia–were consistent with other MMAE ADCs and therefore, we conclude, are not related to the STn target, which is consistent with our tissue cross-reactivity studies demonstrating that overall normal tissue expression of the STn target is insignificant. Our data demonstrate that high-affinity, STn-selective humanized mAbs show promise as therapies for solid tumors.

Abstract
Zusammenfassung
Hintergrund: Die Untersuchung des Bewegungsumfangs ist fester Bestandteil des Assessments bei Patienten mit Nackenschmerz. Bewegungseinschränkungen gelten als sicheres Zeichen für akute Schmerzzustände. Bei chronischem Nackenschmerz ist das Vorhandensein von Bewegungseinschränkungen jedoch fraglich.
Ziel: Die vorliegende Erhebung untersuchte, ob Patienten mit chronischem Nackenschmerz Bewegungseinschränkungen aufweisen.
Methode: 60 gesunde Probanden und 60 Patienten mit chronischem Nackenschmerz wurden mittels Ultraschalltopometrie während zyklischer Bewegungen der HWS bezüglich des Bewegungsumfangs untersucht und die Mittelwerte beider Gruppen auf signifikante Unterschiede überprüft. Ferner erfolgte die Klassifikation der gemessenen Bewegungsumfänge anhand geschlechts- und altersspezifischer Normwerte als normal, hypermobil oder hypomobil. Für die Validität des Befundes „hypomobil“ in Bezug auf die Erkennung des chronischen Nackenschmerzes wurden die Sensitivität, die Spezifität sowie die positive (LR+) und die negative Likelihood Ratio (LR–) ermittelt.
Ergebnisse: Die durchschnittlichen Bewegungsumfänge beider Gruppen unterschieden sich in alle Richtungen signifikant. Im Vergleich zu den Normwerten wiesen mehr als drei Viertel der Teilnehmer beider Gruppen eine normale Beweglichkeit auf. Die Sensitivität des Kriteriums „Hypomobilität“ lag bei maximal 0,23, die Spezifität bei über 0,9, die LR+ bei maximal 0,93 und der niedrigste Wert der LR– bei 0,65.
Schlussfolgerung: Beim chronischen Nackenschmerz ist das Bewegungsausmaß der HWS nicht vermindert. Für das Assessment fehlt ein objektiver Parameter, der mit psychosozialen Variablen korreliert und von Physiotherapeuten gemessen werden kann.

Abstract
OBJECTIVE Alcohol dependence is more prevalent in men than in women. The evidence for how prenatal and adult androgens influence alcohol dependence is limited. We investigated the effects of prenatal and adult androgen activity on alcohol dependence. Moreover, we studied how the behaviours of pregnant women affect their children's prenatal androgen load. METHOD We quantified prenatal androgen markers (e.g., second-to-fourth finger length ratio [2D : 4D]) and blood androgens in 200 early-abstinent alcohol-dependent in-patients and 240 controls (2013-2015, including a 12-month follow-up). We also surveyed 134 women during pregnancy (2005-2007) and measured the 2D : 4D of their children (2013-2016). RESULTS The prenatal androgen loads were higher in the male alcohol-dependent patients compared to the controls (lower 2D : 4D, P = 0.004) and correlated positively with the patients' liver transaminase activities (P < 0.001) and alcohol withdrawal severity (P = 0.019). Higher prenatal androgen loads and increasing androgen levels during withdrawal predicted earlier and more frequent 12-month hospital readmission in alcohol-dependent patients (P < 0.005). Moreover, stress levels (P = 0.002), alcohol (P = 0.010) and tobacco consumption (P = 0.017), and lifetime stressors (P = 0.019) of women during pregnancy related positively to their children's prenatal androgen loads (lower 2D : 4D). CONCLUSION Androgen activities in alcohol-dependent patients and behaviours of pregnant women represent novel preventive and therapeutic targets of alcohol dependence.

Abstract
Abstract
Tumor-associated carbohydrate antigens (TACAs) historically have been challenging targets for antibody therapeutics. Sialyl-Tn (STn) is a cancer specific antigen that is expressed on the cell surface of carcinomas including ovarian, colon, prostate, and pancreatic tumors but is rarely present in normal tissue. STn expression has been linked to innate immune suppression, a chemoresistant phenotype, metastasis, and poor prognosis. Previous attempts to target this antigen in the clinic with synthetic glycan vaccines proved safe but lacked efficacy. We have developed highly selective humanized monoclonal antibodies and antibody drug conjugates (ADCs) targeting TACAs, such as STn. Remarkable sequence homology across all anti-STn mAbs was observed in both heavy and light chains, and hot spots for hypermutation were identified. These antibodies were selected using our glycan microarray that enriches for candidates whose binding is protein-independent, highly selective and demonstrates exceptional target affinity.
Lead humanized candidates demonstrated single digit nanomolar EC50s in ELISA/flow cytometric assays, STn selective cell internalization, and STn specific glycan binding on Siamab’s proprietary glycan array. STn binding sites in common tumor lines (ovarian, gastric and breast) were determined per cell and subsequent cytotoxicity assays in these lines demonstrated in vitro efficacy. Tumor microarray experiments revealed membranous staining in cancerous tissues of various indications. Binding studies of anti-STn antibodies to primary human cancer samples by flow cytometry demonstrated that both tumor and Myeloid-Derived Suppressor Cells (MDSC, both myeloid and granulocytic) express STn. In an OVCAR3 xenograft model, 30 days after the last anti-STn ADC dose was given, groups treated (Q7Dx4) exhibited mean tumor volumes below the Day 1 pre-treatment mean tumor volumes (155mm3). Flow cytometric analysis of tumors from these mice demonstrated that anti-STn ADC treatment reduces STn expression on the primary tumor in a dose-dependent manner (Q7Dx4 vs. single dose) compared to the isotype-ADC control. Our data demonstrates that high-affinity, STn-selective mAbs show promise as therapies for solid tumors and could also target MDSCs to promote antitumor immune responses.

Abstract
Key words: Sialyl Tn, drug resistance, antibody-drug conjugates, cancer stem cells
OBJECTIVES: A successful therapeutic strategy for ovarian cancer will require direct targeting of inherently chemoresistant tumor cells which are comprised in part of cancer stem cells (CSCs) that survive current cytotoxic treatment regimes and drive tumor resurgence. The sialyl-Tn (STn) antigen is a carbohydrate moiety present on tumor cells but rarely seen in normal adult tissue. Importantly, STn has been shown to be present on CSCs in pancreatic, colon, and gastric malignancies. Our objective was to assess the expression of STn and the known CSC marker CD133 in human ovarian cancer (OvCa) cell lines and primary serous carcinomas, and evaluate the ability of STn+ and STn- cells to both grow in an anchorage independent manner and survive standard-of-care cytotoxic therapy. Furthermore, we sought to assess the effect of murine and humanized α -STn antibody-drug conjugates (ADCs) on OvCa cells in vitro and tumor viability in vivo.
METHODS: STn and CD133 expression in established OvCa cell lines was analyzed by flow cytometry. STn-CD133-, STn+CD133-, STn-CD133+ and STn+CD133+ cells were purified from OVCAR3 and OVCAR4 by FACS, plated in soft agar, and incubated for 21 days. Colony forming efficiency of each sub-population was calculated. Unsorted cells were treated in vitro with either murine α -STn-monomethyl auristatin E (MMAE) ADC or vehicle control and cell viability was assessed by MTT assay. Subsequently, cells were treated in vitro with α -STn-MMAE, paclitaxel and carboplatin, or appropriate controls, and the profile of cells surviving 72 hours post-treatment was determined by flow cytometric analysis. Finally, OVCAR3-derived mouse xenografts were treated with murine and humanized α-STn-MMAE, unconjugated mAbs alone, and vehicle control. Mice were assessed regularly for tumor growth and cytotoxic effects.
RESULTS: In the OvCa cell lines OV90, OVCAR3 and OVCAR4, when grown in traditional 2D culture, STn+ cells comprised 98.4%, 40.0%, and 26.4% of the total cell population, respectively. In each of these cell lines, we readily detected STn+CD133+ sub-populations suggesting that STn is expressed on CD133+ ovarian CSCs. Colony formation assays analyzing FACS-purified STn-CD133-, STn+CD133-, STn-CD133+ and STn+ CD133+ sub-populations suggest that STn expression correlates with anchorage independent growth, a characteristic of cell stemness. Paclitaxel and carboplatin treatment in vitro significantly increased the proportion of STn+ and CD133+ cells, demonstrating the chemoresistant characteristics of these cells. Treatment with the murine α-STn-MMAE ADCs reduced the viability of OvCa cell lines in vitro in a dose-dependent manner. Treatment with murine and humanized α -STn- MMAE antibodies in vivo reduced tumor volumes, whereas vehicle treatment did not impede tumor growth. Interestingly, the unconjugated antibody also had a modest negative impact on tumor volume.
CONCLUSION: A novel, highly specific STn antibody identifies the STn antigen in OvCa cell lines and patient samples. STn+ and CD133+ cells demonstrate stem-like characteristics such as anchorage-independent growth and chemoresistance. STn ADCs decreased cell viability in vitro and reduced tumor volumes in vivo, suggesting that specific therapeutic targeting of STn in ovarian tumors may be an effective clinical strategy to eliminate quiescent CSCs.

Abstract
BACKGROUND: Hand hygiene (HH) performing is a must in health care settings because it affects the human lives. Health Care Workers (HCW) must be aware and be trained continuously as regards hand hygiene.AIM: The aim of this article was to evaluate and compare the knowledge before and after an educational training of undergraduate nursing students at an educational institution in Pristine, Kosovo.METHODS: A pre- post survey was conducted in February 2016 at an educational institution in Pristine, Kosovo. The World Health Organization (WHO) questionnaire for hand hygiene knowledge of Health Care Workers (HCW) was used to collect the data.RESULTS: From a total of 100 students, only 13 (13 %) were men and 87 (87%) were women. Their ages ranged between 18-23 years old. Only 55 (55 %) had poor knowledge level, 42 (42%) had moderate knowledge level and only 3 (3%) had good knowledge about HH practices before the training and after the training only 1 (1%) participant was found with poor knowledge, 61 (61%) moderate knowledge and 38 (38 %) good knowledge. The training had a significant impact on the acquisition of HH’ knowledge. This was shown by the significant difference between the total points before and after the training (p <0.001).CONCLUCION: The training should be done consistently and be part of the nursing school curriculum, maintaining a satisfactory level of knowledge about hand hygiene as these students in a near future will face with Hand Hygiene (HH) issues in their daily clinical work.

Abstract
Targeted therapeutics that can differentiate between normal and malignant tumor cells represent the ideal standard for the development of a successful anti-cancer strategy. The Sialyl-Thomsen-nouveau antigen (STn or Sialyl-Tn, also known as CD175s) is rarely seen in normal adult tissues, but it is abundantly expressed in many types of human epithelial cancers. We have identified novel antibodies that specifically target with high affinity the STn glycan independent of its carrier protein, affording the potential to recognize a wider array of cancer-specific sialylated proteins. A panel of murine monoclonal anti-STn therapeutic antibodies were generated and their binding specificity and efficacy were characterized in vitro and in in vivo murine cancer models. A subset of these antibodies were conjugated to monomethyl auristatin E (MMAE) to generate antibody-drug conjugates (ADCs). These ADCs demonstrated in vitro efficacy in STn-expressing cell lines and significant tumor growth inhibition in STn-expressing tumor xenograft cancer models with no evidence of overt toxicity.

Abstract
Abstract
Siamab Therapeutics is developing monoclonal antibodies and antibody drug conjugates (ADCs) targeting tumor-associated carbohydrate antigens such as Sialyl-Tn (STn). These antibodies are selected using a proprietary glycan microarray that enriches for candidates whose binding is protein independent, highly specific and demonstrates exceptional target affinity. STn is a cancer specific antigen that is expressed on the surface of carcinomas including ovarian, colon, prostate, and pancreatic tumors but is rarely present in normal tissue. STn expression has been linked to innate immune suppression, a chemoresistant phenotype, metastasis, and poor prognosis. Previous attempts to target this antigen in the clinic with synthetic glycan vaccines proved safe but lacked efficacy.
Siamab has developed over 20 murine mAbs that bind STn with high affinity and specificity. When formatted as ADCs, anti-STn mAb-ADCs target and selectively kill STn expressing cells and also demonstrate efficacy in multiple xenograft studies. Multiple murine mAbs perform well in IHC studies with multiple solid tumor samples and tissue microarrays and demonstrate high tumor specificity. Remarkable sequence homology across all murine mAbs was observed in both heavy and light chains, and hot spots for hypermutation were identified. Humanization was successfully completed using a selection of mAbs and multiple humanized mAbs maintain their target specific binding, affinity and cytotoxicity in vitro. Our data demonstrates that high-affinity, STn-specific mAbs show promise both as therapies for solid tumors and as a potential tool for the development of biomarkers and companion diagnostics enabling selection of patients most likely to respond to therapy.

Abstract
Tsunamis are rare events with severe consequences. This generates a high demand on accurate simulation results for planning and risk assessment purposes because of the low availability of actual data from historic events. On the other hand, validation of simulation tools becomes very difficult with such a low amount of real-world data. Tsunami phenomena involve a large span of spatial and temporal scales-from ocean basin scales of [Formula: see text] to local coastal wave interactions of [Formula: see text] or even [Formula: see text], or from resonating wave phenomena with durations of [Formula: see text] to rupture with time periods of [Formula: see text]. The scale gap of five orders of magnitude in each dimension makes accurate modelling very demanding, with a number of approaches being taken to work around the impossibility of direct numerical simulations. Along with the mentioned multi-scale characteristic, the tsunami wave has a multitude of different phases, corresponding to different wave regimes and associated equation sets. While in the deep ocean, wave propagation can be approximated relatively accurately by linear shallow-water theory, the transition to a bore or solitary wave train in shelf areas and then into a breaking wave in coastal regions demands appropriate mathematical and numerical treatments. The short duration and unpredictability of tsunami events pose another challenging requirement to tsunami simulation approaches. An accurate forecast is sought within seconds with very limited data available. Thus, efficiency in numerical solution processes and at the same time the consideration of uncertainty play a big role in tsunami modelling applied for forecasting purposes.

Abstract
INTRODUCTION This is about some results of a study called "Appraisal of the educational programmes and qualifications of health professions: a European Comparison" (in short: GesinE). It was carried out in the years 2009-2013, commissioned by the BMBF and supported by the BIBB. It is focussed on Germany, France, Great Britain, the Netherlands and Austria. The objectives have been (i) an inventory and comparative international synoptic presentation of education programmes of 16 health professions, (ii) a comparative international qualification analysis for the professions of radiographer, physiotherapist and nurse and (iii) the exposure of key aspects of the health-care and education systems in the compared countries. METHODS This is a comparative multi-sectional study for which a mixed methods approach with qualitative and quantitative elements was used. RESULTS According to the results of this study it is necessary that current qualification paths and competence profiles of the health professions are developed continuously in Germany. In this process the German education and the secondary education sector should not be underrated. At the same time the results suggest that there are advantages in some aspects in the academic education (which is the norm for most of the analysed professions in the surveyed countries) compared to the existing education programmes in the secondary sector. This in particular applies to the competence for finding and transferring scientific knowledge into practice and for implementing reflected processes for decision making. CONCLUSIONS The results improve the basis of the current debate in Germany about the development and reorganisation of the profiles of health professions and their qualification in a European context.

Abstract
BACKGROUND The aim of this study is the construction of a questionnaire which determines uro-oncological patients' attitudes to their own bodies. The questionnaire will be tested by means of psychometric criteria for suitability. In this way, the emotional-affective and perceptual--cognitive characteristics of the body concept will be detected more effectively. PARTICIPANTS AND METHODS For the construction, 12 interviews with patients were conducted and items from four body concept questionnaires were analysed. Subsequently, a draft version, containing 133 items, was written. A total of 305 participants (PCa n=205; healthy n=100) were questioned in 2 studies. Thereafter the suitability of the items could be checked by psychometric and factor analytical criteria. RESULTS The psychometric testing of the statements led to a selection of the items. 40 items could be established as applicable and were therefore accepted for the final questionnaire. CONCLUSION The indentified scales show good psychometric characteristics and also differentiate between the healthy and the clinical samples. Preliminary analyses prove the validity of the scales, although this should be subjected to further testing for assurance.

Abstract
Personal contextual factors play an essential part in the model of the International Classification of Functioning, Disability and Health (ICF). The WHO has not yet classified personal factors for global use although they impact on the functioning of persons positively or negatively. In 2010, the ICF working group of the German Society of Social Medicine and Prevention (DGSMP) presented a proposal for the classification of personal factors into 72 categories previously arranged in 6 chapters. Now a positioning paper has been added in order to stimulate a discussion about the fourth component of the ICF, to contribute towards a broader and common understanding about the nature of personal factors and to incite a dialogue among all those involved in health care as well as those people with or with-out health problems in order to gain a comprehensive perspective about a person's condition.

Abstract
BACKGROUND Against the background of the continuously growing incidence rates of gerontopsychiatric disorders, their economic dimen-sions, and the effects on persons affected as well as their social environments, the present study focuses on an analysis of the services provided in acute psychiatric care settings for patients with dementia. RESULTS are based on secondary data. AIM OF THE STUDY We aim to compare therapeutic service units of different clusters of occupational groups (physicians/psychologists, nurses/special therapists) for the ICD-10 diagnostic groups F00-F03 and G30 in the years 2010 (starting with July) and 2011. Main research question is how many patients are mappable with 'therapeutic units' (Therapieeinheiten, TE) of the operation and procedures catalogue (OPS). METHODS The present study is based on an analysis of the §21 KHEntgG data record of 35 acute psychiatric facilities. Data collection took place within the project "Versorgungsindikatoren für die Psychiatrie und Psychosomatik (VIPP)", "Supply indicators for psychiatric and psychosomatic settings". The data record implies statewide data of specialised hospitals, university hospitals and departments of psychiatry of the Federal Republic of Germany. RESULTS In total, 5 111 cases were included in the analysis. Nurses and special therapists carried out significantly more therapeutic units in the main diagnoses groups (F01, F03 and G30) and the care groups (regular vs. intensive) than physicians and psychologists (p<0.05). It was not possible to map all patients with the use of therapeutic units (G30 78.8%, F01 83.4%, F03 81.2%). Mapping of patients was significantly higher in the intensive care compared to regular care in both occupational clusters (p<0.05). CONCLUSIONS We demonstrated that the "therapeutic units" of the OPS codes are now used in the routine data (§21 KHEntgG), and that they are able to portray relevant aspects of non-medication therapeutic service. The present study provides a preliminary/exploratory overview on the services provided, mapped by therapeutic units. Future research should focus on the overlap between the category "therapeutic" units and the services actually provided.

Abstract
BACKGROUND For some years therapeutic service catalogues have been established in medical rehabilitation which have broadened our previous understanding of nursing actions. Currently, therapeutic nursing plays a prominent role in neurological early rehabilitation because the operations and procedures coding system (OPS) 8-552 within the DRG-System (Diagnosis Related Groups) states that therapeutic nursing must be carried out by specially trained nursing personnel. This requirement leads to inconsistencies in nursing practice and the medical service of the health insurance (MDK) since a definition of therapeutic nursing is lacking. A previous review of therapeutic nursing in 2003 focused primarily on the development of the therapeutic nursing role, but not on therapeutic nursing itself. The following article contains the first systematic review of the current state of research regarding a definition of therapeutic nursing. For this purpose, a systematic study was conducted to examine if there are, nationally or internationally, any definitions of therapeutic nursing and to identify what the therapeutic aspects of nursing are. METHODS The research included following database; Medline, Cinahl and Embase. Additionally, a research by hand of several German journals as well as textbooks and specialized literature was carried out. RESULTS 5 studies were selected which define the term "therapeutic nursing". Among these are one review, one primary study, one theoretical discussion and one dissertation. Further twenty four studies were identified which do not define the term, but are closely related to the subject, and use or characterize the term in various contexts. CONCLUSIONS The publications examined provided indications of duties, interventions and roles nurses should perform, but not how to carry these out, nor what is therapeutic about the nursing. At the same time, the low number of studies reveals that therapeutic nursing has barely been examined and demonstrates the lack of theoretically grounding through nursing science.

Abstract
In the 20th century, houseparent families represented a significant resource in the long-term care of people with mental illnesses and physical disabilities in diaconical care settings in Germany. In theory, such families could therefore be understood as a type of institutional family: groups which occasionally use familial patterns of reciprocity but are not themselves families. As little empirical material on life in institutional families existed, a qualitative study was undertaken to explore the experiences of contemporary witnesses, particularly those who had experienced the duties and responsibilities of housemothers in the second half of the 20th century. This paper has combined the experiences of residents (n= 8) and biological children of houseparents (n= 5) from a qualitative study (n= 42). The qualitative study took a grounded theory approach, with the phenomena of power and domination forming the central category. The findings show that life in houseparent families of the time was shaped by rules which the family members had to obey. This study explores a highly controversial area which is of great relevance for current mental health nursing practice: the power relations in diaconal families. This demonstrates the importance of integrating autonomy and empowerment into everyday communal life and contributes to professional nursing practice.

Abstract
Expression of E-cadherin, alpha-, beta- and gamma-catenins were studied in 100 patients with primary breast cancer compiled of 57 invasive ductal carcinomas (IDC) and 43 invasive lobular carcinomas (ILC) by means of immunohistochemistry. Loss of E-cadherin was observed in 26 (45.6%), and alpha-, beta- and gamma-catenin expression was lacking in 22 (38.6%), 27 (47.4%) and 22 (38.6%) IDCs, respectively. The expression in ILCs was significantly lower, as compared to IDCs (p<0.001). Immunostaining of both E-cadherin and catenins was completely lacking in 27 (47.4%) IDCs and 30 (93.8%) ILCs. Go-expression of E-cadherin/beta-catenin or E-cadherin/gamma-catenin was preserved more frequently than that of E-cadherin/alpha-catenin complexes. E-cadherin/catenin complex expression showed significant positive correlation with histological differentiation (p=0.037), ER (p=0.017) and PR expression (p=0.052), and negative correlation with c-erbB-2 receptor overexpression (p=0.046). Patients with tumours showing adhesion complexes containing alpha-catenin had an increased overall survival rate compared to other patients. Expression of either E-cadherin or alpha-catenin only, without the formation of entire adhesion complexes, was not correlated with overall survival. Thus, determination of both E-cadherin and catenins is suggested to add further information to estimate the prognosis of breast cancer patients.

Abstract
BACKGROUND An aftercare programme following medical rehabilitation may be beneficial in order to reinforce and stabilize the positive effects of rehabilitation and to encourage individual health-related modifications of behaviour and lifestyle. Medical rehabilitation and the aftercare programme of the German Pension Insurance Fund primarily are intended to sustain earning capacity. As part of an evaluation of the Intensified Rehabilitation Aftercare Programme (IRENA) established by the German Pension Insurance Fund, work-related aspects in orthopaedic patients were analyzed based on various data sources. Firstly, the significance of institutional and individual conditions for utilization of IRENA alongside work was of interest. Secondly, the IRENA participants' judgements of the changes of work-related parameters due to the programme were examined, differentiating specifically by extent of earning capacity impairments as well as by particular work problems. METHODS The data set used for the analysis is composed of person-related routine data of the German Pension Insurance Fund relative to IRENA records of the year 2007 (n=30 663), interview data from orthopaedic rehabilitation centres providing IRENA (n=225), and questionnaires of IRENA participants (n=750) that were either collected during a broad evaluation of the IRENA programme or provided by the German Pension Insurance Fund. RESULTS The results show that the compatibility of IRENA and work is facilitated by the institutional conditions. However, differences between inpatient and outpatient settings have to be recognized. The possibilities to participate in IRENA throughout the day frequently are more diverse in an outpatient setting. In contrast to inpatient centres, outpatient rehabilitation centres see clearly better chances for patients to return to work and to participate in IRENA alongside. With respect to the work-related parameters (work ability, periods of sick leave), clear improvements were reported by participants from the start of rehabilitation to the survey time after the end of IRENA. Particular work problems were reported by 33% of the IRENA participants. The work ability at the end of rehabilitation was found to have been the essential factor for improvement of work ability following IRENA. Particular work problems, however, had no influence, these individuals profited from IRENA to an equal extent. CONCLUSIONS Institutional and individual view show that IRENA is compatible with utilization alongside work. Also, IRENA combined with prior medical rehabilitation will bring about subjective improvements in health and work-related parameters.

Abstract
The project "Family midwives in Saxony-Anhalt" was evaluated by a multidimensional approach in order to document the subjective perspective of the mothers as well as the networking of health care and child welfare professionals, while caring for highly vulnerable families. The documentation of 734 cases and quantitative data of 33 family midwives were analyzed. Ten mothers were interviewed and problem-focused expert interviews were carried out with 39 health care and child welfare professionals. The method of coding the interview texts was both open and guided by the research questions. After finishing the qualification course and while caring for highly vulnerable families, the networking of family midwives with child welfare professionals significantly increased. Besides the family midwives and the youth welfare office, the antenatal counseling centers were important "gatekeepers". An important ingredient for constructive networking and care for families is trust which draws on client-oriented care, availability, and advocacy by the family midwives. While the family midwives are respected as partners by the professionals of the child welfare system, networking with obstetricians and hospitals is unsatisfactory. In order to improve this, the latter must be a future goal.

Abstract
BACKGROUND It is known that many patients with schizophrenia show non-adherence with regard to antipsychotic medication. Furthermore, many studies indicate cognitive deficits in schizophrenic patients. In this review, we compare the results of studies examining the relationship of non-adherence and cognitive performance. METHOD Based on a systematic literature review, the impact of cognitive performance on the adherence behaviour of patients with schizophrenia was examined. RESULTS We found 18 studies analysing the impact of cognitive performance on adherence behaviour. Most studies indicated that patients with stronger cognitive impairments show lower adherence behaviour. Possible causal mechanisms are discussed.
