[Against oblivion: Remembering the first Jewish women doctors of the German Society for Internal Medicine]. / Gegen das Vergessen: Jüdische Ärztinnen der Deutschen Gesellschaft für Innere Medizin im Porträt.

In 1933, the German Society for Internal Medicine (DGIM) willingly adapted to the ideology and politics of the Nazi regime. Seven members of the Society were Jewish women doctors, women making up 1 % of all members by that time. By pursuing a career in medicine, these women refused to take on the traditional woman's role, opting instead for an unusual path in life and making the medical profession their central mission despite difficult conditions. Under Nazi dictatorship, they were deprived of their livelihood, disenfranchised, persecuted and forced into exile. While this also applies to their male colleagues, Jewish women doctors are considerably less visible. This article presents and contextualises their biographies in order to increase their visibility and integrate them more explicitly into today's culture of remembrance.

[Recommendations for Drug Treatment in Patients with Multimorbidity]. / Entwicklung von Empfehlungen zum Management von Arzneimitteltherapie bei Multimorbidität.

Applying guidelines in patients with multimorbidity can result in dangerous or contraindicated drug-drug and drug-disease-interactions. A representative working group of medical scientific associations identifies such therapeutic conflicts and develops management strategies that will be published as a formally consensus based (S2K) guideline. Rational, aims and methods used are described, as well as evaluation and updating of recommendations.

Toward Historical Accountability and Remembrance: The German Society for Internal Medicine and Its Legacies From the Nazi Past.

After decades of silence, the German Society for Internal Medicine (DGIM) has made considerable efforts to come to terms with its role and actions during the Nazi era (1933 to 1945). This is particularly important because, with more than 27 000 members, the DGIM is the largest medical society in present-day Germany. Since 1882, the society's annual congress in Wiesbaden has provided a forum and focus for the key medical topics of the day. Based on ongoing historical research, this article is organized in 2 parts. The first describes how the DGIM willingly adapted to the ideology and politics of the Nazi regime, showing no solidarity with its persecuted Jewish members. To illustrate their fates, the cases of Leopold Lichtwitz, who was forced to resign as elected chairman in 1933, and committee member Julius Bauer are investigated. Both men emigrated to the United States. Light is also shed on the decisions of those who led the society during the Nazi era and on the involvement of high-ranking members in medical crimes. The second part of the article analyzes developments in the postwar period and considers why it took so long to hold up a mirror to the past. Although critical voices could be heard from both outside and within the society, they remained isolated and without consequence. Only the past 2 decades have brought about both general and specific developments toward historical accountability and an active culture of remembrance. With a declaration first published in 2015, a new website bringing history and memory together, and a strong commitment to the norms and values of liberal democracy, the DGIM has found its way to a clear position-and has lessons to teach.

[Medicine and Economy: Measures for a Science Based, Patient-Centred and Resource Conscious Care. The Association of Scientific Medical Societies' (AWMF) Strategy Paper]. / Medizin und Ökonomie: Maßnahmen für eine wissenschaftlich begründete, patientenzentrierte und ressourcenbewusste Versorgung. Ein Strategiepapier der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF).

The AWMF and its medical societies perceive an increasing dominance of economic targets in the hospital health care sector, leading to impairment of patient care. While resource use in health care should be appropriate, efficient and fairly allocated, "economization" creates a burdensome situation for physicians, nurses and other health care professionals.The AMWF and the medical societies studied causes and developed measures for a scientific, patient-centred and resource-conscious medical care. Disincentives due to the remuneration system, number and equipment of hospitals resp. specialist departments and their basic funding need to be overcome. Proposed actions relate to the patient-doctor-level, the management level of hospitals and the level of planning and financing hospitals including compensation of hospital care. To place patients and their health in the forefront again, joint efforts of all stakeholders in health care are needed.

[Choosing Wisely: rationale, implementation, and evaluation]. / Klug entscheiden: Rationale, Umsetzung, Evaluation.

"Klug entscheiden" (Choosing Wisely) is an initiative launched by the German Society for Internal Medicine (DGIM) to boost the quality of medical indication by identifying both medical/therapeutic over- and underuse. Twelve specialist societies for internal medicine and DGIM associated societies develop corresponding recommendations which are subsequently evaluated and rejected or approved in a structured procedure by a multidisciplinary commission. Since 2016, 115 positive and negative recommendations have been developed and released for print media, radio and television. Physicians can obtain the DGIM/BDI* certificate "Klug entscheiden". First steps have been undertaken to implement "Klug entscheiden" in medical education. The wide dissemination and intense discussions give a reason to hope that positive and negative recommendations will be put into practice and that the awareness towards the relevance of the quality of medical indication will grow. And finally, specific recommendations are to be developed the implementation of which can be evaluated prospectively. * Professional organization of German specialists for internal medicine.

[Representation of Internal Medicine in G-DRG System - Analysis of Reasons for Prolonged Length of Stay]. / Innere Medizin im G-DRG-System.

Background There is an ongoing discussion within the German Society of Internal Medicine (DGIM) and the Professional Association of German Internists (BDI) about the appropriate depiction and remuneration of internal medicine in the G-DRG. Method Therefore, cases with a significantly prolonged length of stay were analyzed in a multicenter study. 124 cases from 6 hospitals were collected for evaluation. Results The results show that the observed prolongation of hospitalization was mainly due to medical reasons. Discussion Thus, patients with unclear symptoms and consequently need for a thorough workup could not be identified to cause longer inpatient stay. Instead, treatment complications and comorbidities led to extended hospitalization. The results also reveal prolonged hospitalization as a consequence of unsettled or delayed postdischarge care e. g. in rehabilitation facilities.

A variant in the heart-specific fatty acid transport protein 6 is associated with lower fasting and postprandial TAG, blood pressure and left ventricular hypertrophy.

Fatty acid transport protein 6 (FATP6) is primarily expressed in the heart and seems to be involved in cardiac fatty acid uptake. Therefore, we investigated whether a variation in the 5'-untranslated region of the FATP6 gene is associated with features of the metabolic syndrome and signs of myocardial alteration or heart failure. A total of 755 male participants from a Metabolic Intervention Cohort Kiel were genotyped for the FATP6-7T>A polymorphism (rs2526246) and phenotyped for features of the metabolic syndrome. Participants underwent a glucose tolerance test and the postprandial assessment of metabolic variables after a standardised mixed meal. Left ventricular heart function was evaluated in fifty-four participants. Fasting (P = 0·01) and postprandial (P = 0·02) TAG concentrations were significantly lower in AA homozygotes when compared with wild-type carriers. Homozygosity of allele A was associated with significantly lower postprandial insulin concentrations after a glucose load and significantly lower systolic (P = 0·01) and diastolic (P = 0·01) blood pressure values compared with wild-type carriers. Accordingly, left ventricular heart mass was significantly lower in twenty-seven AA homozygotes in comparison with twenty-seven TT homozygotes, matched for BMI (P = 0·04). In conclusion, the effects of the FATP6 polymorphism on TAG are mediated by affluent dietary fat. The FATP6-7T>A polymorphism may protect from traits of the metabolic syndrome and CVD.

Polymorphisms in the 3'-untranslated region of the CDH1 gene are a risk factor for primary gastric diffuse large B-cell lymphoma.

BACKGROUND: Primary gastric B-cell lymphomas arise from mucosa-associated lymphatic tissue (MALT) in patients with chronic Helicobacter pylori infection. We investigated whether germline variants in the CDH1 gene, coding for E-cadherin, genetically predispose patients to primary gastric B-cell lymphoma. DESIGN AND METHODS: Single marker analyses of the CDH1 gene were conducted in patients with primary gastric B-cell lymphoma (n=144), in patients with primary gastric high-grade lymphoma (n=61), and in healthy blood donors (n=361). Twelve single nucleotide polymorphisms were genotyped by TaqMan(®) technology. Allelic imbalance was tested by pyrosequencing and clone direct sequencing of heterozygote genomic and cDNA. Mutation detection was conducted around the poly-A signal of the CDH1 3'-untranslated region. The influence of the 3'-untranslated region on protein translation was determined by a luciferase reporter assay. RESULTS: Single marker analyses identified two single nucleotide polymorphisms in strong linkage disequilibrium located in the CDH1 3'-untranslated region. One of them was significantly associated with primary gastric diffuse large B-cell lymphomas after correction for multiple testing and this association was confirmed in an independent sample set. Patients homozygous for the rare T allele (rs1801026) had a 4.9-fold increased risk (95% CI: 1.5-15.9) of developing primary gastric diffuse large B-cell lymphoma. Allelic imbalance and reporter gene assays indicated a putative influence on mRNA stability and/or translational efficacy. CONCLUSIONS: We identified variants in CDH1 as the first potential genetic risk factors for the development of primary gastric diffuse large B-cell lymphomas. One of the potentially causative variants affects allelic CDH1 expression. These findings support the hypothesis that besides somatic alterations of B-cells, germline variants in the CDH1 gene contribute to a predisposition to the development of primary gastric diffuse large B-cell lymphomas.

Association of postprandial and fasting triglycerides with traits of the metabolic syndrome in the Metabolic Intervention Cohort Kiel.

OBJECTIVE: Postprandial (pp) lipid metabolism is associated with insulin resistance and type 2 diabetes. In young men, pp triglycerides (TGs) are more strongly associated with traits of metabolic syndrome (MS) than fasting TGs. We established a cohort of middle-aged men selected for traits of MS and pp lipid metabolism to determine if fasting TGs or pp TGs are more closely related to MS. RESEARCH DESIGN AND METHODS: A total of 1558 men were characterized for MS. A total of 755 men underwent an oral metabolic tolerance test consisting of a standardized high-fat meal and an oral glucose tolerance test. Blood samples were drawn in the fasting state and hourly until 9 h to determine pp TGs and free fatty acids. Glucose and insulin were analyzed until 5 h pp. RESULTS: In the overall cohort, 329 subjects (21.1%) had a complete MS based on the Adult Treatment Panel III criteria, and 650 subjects (41.7%) had a complete MS based on the International Diabetes Federation criteria. The association of pp TGs with MS parameters was not stronger than the association of fasting TGs with them. Pp TGs were independently associated with beta-cell function. CONCLUSIONS: Pp TGs did not show a higher correlation with MS traits than fasting TGs. This finding is probably due to the high incidence of overweight subjects in this middle-aged cohort.

Ablation of gly96/immediate early gene-X1 (gly96/iex-1) aggravates DSS-induced colitis in mice: role for gly96/iex-1 in the regulation of NF-kappaB.

BACKGROUND: Inflammatory bowel diseases (IBDs) result from environmental and genetic factors and are characterized by an imbalanced immune response in the gut and deregulated activation of the transcription factor NF-kappaB. Addressing the potential role of gly96/iex-1 in the regulation of NF-kappaB in IBD, we used the dextran sodium sulfate (DSS) colitis model in mice in which the gly96/iex-1 gene had been deleted. METHODS: C57BL/6 mice of gly96/iex-1(-/-) or gly96/iex-1(+/+) genotype were treated continuously with 4% DSS (5 days) and repeatedly with 2% DSS (28 days) for inducing acute and chronic colitis, respectively. In addition to clinical and histological exploration, colon organ culture and bone marrow-derived cells (BMCs) were analyzed for chemo/cytokine expression and NF-kappaB activation. RESULTS: Compared to wildtype littermates, gly96/iex-1(-/-) mice exhibited an aggravated phenotype of both acute and chronic colitis, along with a greater loss of body weight and colon length. Colonic endoscopy revealed a higher degree of hyperemia, edema, and bleeding in gly96/iex-1(-/-) mice, and immunohistochemistry detected massive mucosal infiltration of leukocytes and marked histological changes. The expression of proinflammatory chemo- and cytokines was higher in the colon of DSS-treated gly96/iex-1(-/-) mice, and the NF-kappaB activation was enhanced particularly in the distal colon. In cultured BMCs from gly96/iex-1(-/-) mice, Pam(3)Cys(4) treatment induced expression of proinflammatory mediators to a higher degree than in gly96/iex-1(+/+) BMCs, along with greater NF-kappaB activation. CONCLUSIONS: Based on the observation that genetic ablation of gly96/iex-1 triggers intestinal inflammation in mice, we demonstrate for the first time that gly96/iex-1 exerts strong antiinflammatory activity via its NF-kappaB-counterregulatory effect.

G protein-coupled receptor 43 is essential for neutrophil recruitment during intestinal inflammation.

Molecular danger signals attract neutrophilic granulocytes (polymorphonuclear leukocytes (PMNs)) to sites of infection. The G protein-coupled receptor (GPR) 43 recognizes propionate and butyrate and is abundantly expressed on PMNs. The functional role of GPR43 activation for in vivo orchestration of immune response is unclear. We examined dextrane sodium sulfate (DSS)-induced acute and chronic intestinal inflammatory response in wild-type and Gpr43-deficient mice. The severity of colonic inflammation was assessed by clinical signs, histological scoring, and cytokine production. Chemotaxis of wild-type and Gpr43-deficient PMNs was assessed through transwell cell chemotactic assay. A reduced invasion of PMNs and increased mortality due to septic complications were observed in acute DSS colitis. In chronic DSS colitis, Gpr43(-/-) animals showed diminished PMN intestinal migration, but protection against inflammatory tissue destruction. No significant difference in PMN migration and cytokine secretion was detected in a sterile inflammatory model. Ex vivo experiments show that GPR43-induced migration is dependent on activation of the protein kinase p38alpha, and that this signal acts in cooperation with the chemotactic cytokine keratinocyte chemoattractant. Interestingly, shedding of L-selectin in response to propionate and butyrate was compromised in Gpr43(-/-) mice. These results indicate a critical role for GPR43-mediated recruitment of PMNs in containing intestinal bacterial translocation, yet also emphasize the bipotential role of PMNs in mediating tissue destruction in chronic intestinal inflammation.

Investigation of innate immunity genes CARD4, CARD8 and CARD15 as germline susceptibility factors for colorectal cancer.

BACKGROUND: Variation in genes involved in the innate immune response may play a role in the predisposition to colorectal cancer (CRC). Several polymorphisms of the CARD15 gene (caspase activating recruitment domain, member 15) have been reported to be associated with an increased susceptibility to Crohn disease. Since the CARD15 gene product and other CARD proteins function in innate immunity, we investigated the impact of germline variation at the CARD4, CARD8 and CARD15 loci on the risk for sporadic CRC, using a large patient sample from Northern Germany. METHODS: A total of 1044 patients who had been operated with sporadic colorectal carcinoma (median age at diagnosis: 59 years) were recruited and compared to 724 sex-matched, population-based control individuals (median age: 68 years). Genetic investigation was carried out following both a coding SNP and haplotype tagging approach. Subgroup analyses for N = 143 patients with early manifestation of CRC (

Terminal part of thoracic duct: high-resolution US imaging.

PURPOSE: To assess ultrasonographic (US) examination results of the cervical part of the thoracic duct, to provide standard diameters, and to evaluate the diameter of the cervical thoracic duct in certain diseases suspected to involve an abnormal load of chyle (liver, heart, and inflammatory bowel diseases). MATERIALS AND METHODS: The study was approved by the institutional review committee, and written informed consent was obtained from all subjects. Diameter and variations of the cervical thoracic duct were assessed by using US in 265 healthy volunteers (age range, 21-82 years) from a population-based study, in 196 subjects with documented liver cirrhosis (age range, 19-87 years), in 68 subjects with chronic hepatitis (age range, 17-73 years), in 39 subjects with congestive heart failure (age range, 46-85 years), and in 17 subjects with inflammatory bowel disease (age range, 18-66 years). US examinations were performed with high-resolution linear probes (7-12 MHz). RESULTS: A standard imaging approach guided by anatomic structures was established. Dynamic imaging of the chyle flow and valve function was possible. The thoracic duct was visualized in 564 (96%) of 585 examinations. The average thoracic duct diameter in healthy volunteers was 2.5 mm, which was independent of the subjects' age. The diameter was significantly higher in subjects with congestive heart failure (6.3 mm, P < .0001) and liver cirrhosis (5.6 mm, P < .0001). Anatomic variations were present in 27% of subjects. CONCLUSION: High-resolution US with linear probes allows assessment of the cervical thoracic duct with high detection rates. Recognition of local anatomy, diameter, and chyle flow may aid functional assessment.

The expression of the beta-defensins hBD-2 and hBD-3 is differentially regulated by NF-kappaB and MAPK/AP-1 pathways in an in vitro model of Candida esophagitis.

BACKGROUND: Candida albicans resides on epithelial surfaces as part of the physiological microflora. However, under certain conditions it may cause life-threatening infections like Candida sepsis. Human beta-defensins (hBDs) are critical components of host defense at mucosal surfaces and we have recently shown that hBD-2 and hBD-3 are upregulated in Candida esophagitis. We therefore studied the role of Candidate signalling pathways in order to understand the mechanisms involved in regulation of hBD-expression by C. albicans. We used the esophageal cell line OE21 and analysed the role of paracrine signals from polymorphonuclear leukocytes (PMN) in an in vitro model of esophageal candidiasis. RESULTS: Supernatants of C. albicans or indirect coculture with C. albicans induces upregulation of hBD-2 and hBD-3 expression. PMNs strongly amplifies C. albicans-mediated induction of hBDs. By EMSA we demonstrate that C. albicans activates NF-kappaB and AP-1 in OE21 cells. Inhibition of these pathways revealed that hBD-2 expression is synergistically regulated by both NF-kappaB and AP-1. In contrast hBD-3 expression is independent of NF-kappaB and relies solely on an EGFR/MAPK/AP-1-dependent pathway. CONCLUSION: Our analysis of signal transduction events demonstrate a functional interaction of epithelial cells with PMNs in response to Candida infection involving divergent signalling events that differentially govern hBD-2 and hBD-3 expression.

Adult hereditary fructose intolerance.

Hereditary fructose intolerance (HFI) is an under-recognized, preventable life-threatening condition. It is an autosomal recessive disorder with subnormal activity of aldolase B in the liver, kidney and small bowel. Symptoms are present only after the ingestion of fructose, which leads to brisk hypoglycemia, and an individual with continued ingestion will exhibit vomiting, abdominal pain, failure to thrive, and renal and liver failure. A diagnosis of HFI was made in a 50-year-old woman on the basis of medical history, response to IV fructose intolerance test, demonstration of aldolase B activity reduction in duodenal biopsy, and molecular analysis of leukocyte DNA by PCR showed homozygosity for two doses of mutant gene. HFI may remain undiagnosed until adult life and may lead to disastrous complications following inadvertent fructose or sorbitol infusion. Several lethal episodes of HFI following sorbitol and fructose infusion have been reported. The diagnosis can only be suspected by taking a careful dietary history, and this can present serious complications.

Up-regulation of L1CAM in pancreatic duct cells is transforming growth factor beta1- and slug-dependent: role in malignant transformation of pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) is thought to originate from ductal structures, exhibiting strong desmoplastic reaction with stromal pancreatic myofibroblasts (PMF), which are supposed to drive PDAC tumorigenesis. Previously, we observed high expression of the adhesion molecule L1CAM (CD171) in PDAC cells accounting for chemoresistance. Thus, this study aimed to investigate whether PMFs are involved in the induction of tumoral L1CAM and whether this contributes to malignant transformation of pancreatic ductal cells and PDAC tumorigenesis. Immunohistochemistry of tissues from chronic pancreatitis specimens revealed considerable L1CAM expression in ductal structures surrounded by dense fibrotic tissue, whereas no L1CAM staining was seen in normal pancreatic tissues. Using the human pancreatic duct cell line H6c7, we show that coculture with PMFs led to a transforming growth factor-beta1 (TGF-beta1)-dependent up-regulation of L1CAM expression. Similarly, L1CAM expression increased in monocultured H6c7 cells after administration of exogenous TGF-beta1. Both TGF-beta1- and PMF-induced L1CAM expression were independent of Smad proteins but required c-Jun NH(2)-terminal kinase activation leading to the induction of the transcription factor Slug. Moreover, Slug interacted with the L1CAM promoter, and its knockdown abrogated the TGF-beta1- and PMF-induced L1CAM expression. As a result of L1CAM expression, H6c7 cells acquired a chemoresistant and migratory phenotype. This mechanism of TGF-beta1-induced L1CAM expression and the resulting phenotype could be verified in the TGF-beta1-responsive PDAC cell lines Colo357 and Panc1. Our data provide new insights into the mechanisms of tumoral L1CAM induction and how PMFs contribute to malignant transformation of pancreatic duct cells early in PDAC tumorigenesis.

Germline variations of the MALT1 gene as risk factors in the development of primary gastric B-cell lymphoma.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a histologically distinct tumour derived from MALT acquired as a result of Helicobacter pylori infection. The genetic susceptibility to develop primary gastric B-cell lymphoma in patients with chronic H. pylori infection is unknown. MALT1 plays a key role in malignant B-cell transformation and lymphoma progression. Thus, we investigated germline variations of MALT1 as risk factors for gastric lymphoma in a large cohort from a European multicentre study and in total 214 lymphoma patients, 593 H. pylori infected controls and 348 healthy blood donors were genotyped for four single nucleotide polymorphisms (SNPs) covering the MALT1 locus by Taqman technology. Haplotype and single marker analyses were conducted for association testing in a case-control setting. A distinct haplotype was identified that showed a trend towards protection from high-grade and low-grade lymphomas. In single marker analysis individuals homozygous for the rare allele G of SNP3 (rs12969413) were significantly protected only from gastric high-grade lymphoma compared with controls (p=0.002, odds ratio (OR): 0.2, Wald 95% confidence interval (CI): 0.1
