Colonoscopy and reduction of colorectal cancer risk by molecular tumor subtypes: a population-based case-control study
2020
AbstractObjectiveIn previous studies, the protective effect of colonoscopy was generally stronger for distal than for proximal colorectal cancer (CRC). This study aimed to investigate whether the association of colonoscopy and CRC risk varies according to major molecular pathological features and pathways of CRC.DesignPopulation-based case-control study from Germany, including 2132 patients with a first diagnosis of CRC and information on major molecular tumor markers, and 2486 control participants without CRC. Detailed participant characteristics were collected by standardized questionnaires and information on previous colonoscopy was derived from medical records. Polytomous logistic regre…
Standardized long-term follow-up after endoscopic resection of large, nonpedunculated colorectal lesions: a prospective two-center study.
2014
Endoscopic removal of large, nonpedunculated colorectal lesions is challenging. Long-term outcome data based on standardized protocols, including detailed inspection of the resection site, are scarce. The aims of the present study were to evaluate the safety and efficacy of endoscopic resection (ER) of large, nonpedunculated lesions (LNLs;20 mm) and to assess the long-term recurrence rate afterward.A total of 243 consecutive patients (141 men, 102 women) with 252 adenomas (20 mm) was followed up using a standardized protocol after complete ER. After endoscopic treatment, the patients received standardized follow-up examinations after 3-6 months and 12 months. The postpolypectomy scar was re…
The intestinal microbiota modulates the anticancer immune effects of cyclophosphamide
2013
The Microbiota Makes for Good Therapy The gut microbiota has been implicated in the development of some cancers, such as colorectal cancer, but—given the important role our intestinal habitants play in metabolism—they may also modulate the efficacy of certain cancer therapeutics. Iida et al. (p. 967 ) evaluated the impact of the microbiota on the efficacy of an immunotherapy [CpG (the cytosine, guanosine, phosphodiester link) oligonucleotides] and oxaliplatin, a platinum compound used as a chemotherapeutic. Both therapies were reduced in efficacy in tumor-bearing mice that lacked microbiota, with the microbiota important for activating the innate immune response against the tumors. Viaud et…
Risk of second primary cancers in women diagnosed with endometrial cancer in G erman and S wedish cancer registries
2017
Along with the increasing incidence and favorable prognosis, more women diagnosed with endometrial cancer may develop second primary cancers (SPCs). We aimed at investigating risk of SPCs after endometrial cancer in Germany and Sweden to provide insight into prevention strategies for SPCs. Endometrial cancer patients diagnosed at age ≥15 years in Germany during 1997-2011 and in Sweden nationwide during 1997-2012 were selected. Standardized incidence ratios (SIRs), calculated as the ratio of observed to expected numbers of cases, were used to assess the risk of a specific second cancer after endometrial cancer for both German and Swedish datasets. Among 46,929 endometrial cancer survivors in…
Multicenter Phase II Study of Lurbinectedin in BRCA-Mutated and Unselected Metastatic Advanced Breast Cancer and Biomarker Assessment Substudy
2018
Purpose This multicenter phase II trial evaluated lurbinectedin (PM01183), a selective inhibitor of active transcription of protein-coding genes, in patients with metastatic breast cancer. A unicenter translational substudy assessed potential mechanisms of lurbinectedin resistance. Patients and Methods Two arms were evaluated according to germline BRCA1/2 status: BRCA1/2 mutated (arm A; n = 54) and unselected ( BRCA1/2 wild-type or unknown status; arm B; n = 35). Lurbinectedin starting dose was a 7-mg flat dose and later, 3.5 mg/m2 in arm A. The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST). The translational substudy of resist…
Implicitly measured aggressiveness self-concepts in women with borderline personality disorder as assessed by an Implicit Association Test.
2020
Abstract Background Aggressiveness resulting from inappropriately intense anger plays a major role in borderline personality disorder (BPD) and research using self-report measures has consistently found elevated levels of aggression in this condition. However, while self-report assesses explicit dimensions of the self-concept, it cannot elucidate implicit processes that are at least equally important as they guide the perceptions of the self and influence behavioral responses. The present study aimed to extend the research on aggressiveness self-concepts in BPD utilizing an indirect latency-based measure. Methods Twenty-nine female inpatients with BPD and 21 healthy women were assessed with…
Memory bias for schema-related stimuli in individuals with bulimia nervosa
2010
This study investigates whether individuals with bulimia nervosa (BN) have a memory bias in relation to explicit memory (cued and free recall vs. verbal and pictorial recognition tasks). Twenty-five participants diagnosed with BN and 27 normal controls (NC) were exposed to body-related, food-related, and neutral TV commercials, and then recall and recognition rates were assessed. Poorer recognition and recall of body-related stimuli was found for BN in comparison to NC, suggesting a memory bias. Results are discussed in relation to previous studies, along with suggestions as to how future studies can gain more insight into dysfunctions in information processing that can lead to the maintena…
The Cycle of Violence: Examining Attitudes Toward and Experiences of Corporal Punishment in a Representative German Sample
2018
The use of corporal punishment (CP) is controversial despite the negative consequences of its use that have been documented. Consequences include the use of CP by those who experienced CP themselves, described in the theory of the cycle of violence. There are little data on the cycle of violence, especially on those who break it and in representative samples. This study examines the cycle of violence in a representative sample by analyzing experiences of and attitudes toward CP. Attitudes toward, and own experiences of, CP by their parents were assessed in a sample of 2,519 individuals (female 54.6%, age range = 14-99 years, M = 48.9 years). Latent class analysis (LCA) was used to identify…
Comparison of bipolar and tetrapolar impedance techniques for assessing fat mass.
2004
Whole body fat mass (BF) can be predicted by different bioimpedance (BIA) techniques measuring the whole body (tetrapolar hand-to-foot technique, HF), lower body (bipolar foot-to-foot technique, FF), or upper body (bipolar hand-to-hand technique, HH). This study analyzed 146 healthy volunteers (age 18-84 years) for whether these three techniques differ in their estimates of BF, and whether sex and age of the subjects influence estimates of BF. Reproducibility of the techniques was tested by calculating the technical error (TE). Effects of BIA technique, sex, and age on predicted BF were analyzed with ANOVA for repeated measurements in a mixed effect design. Results showed high reproducibili…
B cell immunosenescence: different features of naive and memory B cells in elderly.
2011
Elderly people show a reduced protection against new infections and a decreased response to vaccines as a consequence of impairment of both cellular and humoral immunity. In this paper we have studied memory/naive B cells in the elderly, evaluating surface immunoglobulin expression, production of the pro- and anti-inflammatory cytokines, tumor necrosis factor (TNF)-α and interleukin (IL)-10, and presence of somatic hypermutation, focusing on the IgG(+)IgD(-)CD27(-) double negative (DN) B cells that are expanded in the elderly. Our results show that naive B cells from young donors need a sufficiently strong stimulus to be activated "in vitro", while naive B cells from old subjects are able t…
