Bibliographie Peter Borowsky

Peter Borowsky (1938–2000) war ein engagierter Geschichtsforscher und begeisternder Geschichtsvermittler. Mehr als 30 Jahre lehrte er am Historischen Seminar der Universität Hamburg Neuere Geschichte. Er prägte Generationen von Studierenden nachhaltig durch seine Kompetenz und seine Art, Geschichte lebendig zu vermitteln. Diese wird auch in den 14 Beiträgen zur deutschen Geschichte im 19. und 20. Jahrhundert deutlich, die hier erstmals veröffentlicht werden. Die Themenpalette reicht von den Hohenzollern bis zur politischen Kultur der Bundesrepublik Deutschland, umfasst die Studenten in der Revolution von 1848, Hamburger Geschichte im 19. Jahrhundert, die Entwicklung von der Weimarer Republik zum „Dritten Reich“, die deutschen Beziehungen zu osteuropäischen Staaten und den USA. Zwei Texte beschäftigen sich anschaulich mit der Geschichte der deutschen Geschichtswissenschaft und dem „Historikerstreit“.Peter Borowsky (1938-2000) was a committed historian and enthusiastic historian. For more than 30 years he taught modern history at the History Department of the University of Hamburg. He left a lasting mark on generations of students through his competence and his way of conveying history in a lively way. This is also evident in the 14 contributions to German history in the 19th and 20th centuries, which are published here for the first time. The topics range from the Hohenzollern region to the political culture of the Federal Republic of Germany and include students in the revolution of 1848, Hamburg\u27s 19th century history, the development from the Weimar Republic to the "Third Reich", German relations with Eastern European countries and the USA. Two texts deal vividly with the history of German historiography and the "Historian\u27s Dispute"

Impact of Patient Demographic Factors on Preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function, Pain Interference, and Depression Computer Adaptive Testing Scores in Patients Undergoing Shoulder and Elbow Surgery

Background: There has been a growing emphasis in orthopaedics on providing patient-centered care. The US National Institutes of Health launched the Patient-Reported Outcomes Measurement Information System (PROMIS) initiative that incorporates patient-reported outcome measures across a number of medical domains. The relationship between PROMIS domains and the impact of patient demographic factors in those undergoing upper extremity surgery remains unclear. Purpose/Hypothesis: The goal of this study was to investigate the correlation between physical function, pain interference, and depression in patients undergoing shoulder and elbow surgery as measured by PROMIS computer adaptive testing (CAT) forms and to determine the impact of patient demographic factors. We hypothesized that there would be a significant negative correlation between physical function and both pain interference and depression in this patient population. Study Design: Cross-sectional study; Level of evidence, 3. Methods: All patients who underwent elective shoulder or elbow surgery by 3 shoulder, elbow, and/or sports medicine fellowship–trained orthopaedic surgeons were included in the study. Preoperative PROMIS–Upper Extremity (PROMIS-UE), PROMIS–Pain Interference (PROMIS-PI), and PROMIS-Depression (PROMIS-D) CAT scores were analyzed. Pearson correlations were calculated between PROMIS domains as well as between PROMIS outcomes with patient demographic factors. Results: Preoperative PROMIS CAT scores for all 3 domains were collected and analyzed from 172 unique patients (516 individual CAT forms) with shoulder and elbow injuries. A negative correlation of moderate strength was found between the PROMIS-UE and PROMIS-PI (R = –0.61; P \u3c.001), and a negligible correlation was found between the PROMIS-UE and PROMIS-D (R = –0.28; P \u3c.001). When stratified by patient demographic factors, the correlation between the PROMIS-UE and PROMIS-PI was stronger in female patients compared with male patients (R = –0.77 vs –0.46, respectively; P \u3c.001 for both), stronger in black patients compared with white patients (R = –0.72 vs –0.56, respectively; P \u3c.001 for both), and highest in current tobacco users (R = –0.80; P \u3c.001). Conclusion: Before shoulder and elbow surgery, patients demonstrated impairments in physical function and pain interference as measured by CAT forms, with a moderate negative correlation between baseline upper extremity physical function and pain interference scores. In certain subpopulations, such as female patients, black patients, and current tobacco users, the correlations between these tested domains were stronger than in other groups

Feasibility of PROMIS CAT Administration in the Ambulatory Sports Medicine Clinic With Respect to Cost and Patient Compliance: A Single-Surgeon Experience.

Background: Pay-for-performance reimbursement models are becoming increasingly popular, but the implementation of a routine patient-reported outcome (PRO) collection system places additional burden on both the patient and the provider. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed in an effort to make PRO collection more practical and efficient, but providers may be reluctant to embrace a transition to a PROMIS-based clinical outcome registry. Hypothesis: PROMIS can be successfully incorporated into daily clinical practice, with an overall patient compliance rate of 80%. Study Design: Cross-sectional study; Level of evidence, 3. Methods: As part of routine practice, all patients presenting to a single surgeon\u27s sports medicine clinic for an appointment were asked to complete a series of PROMIS computerized adaptive tests (CATs), including PROMIS Physical Function, Physical Function-Upper Extremity, Pain Interference, and Depression subscales. Overall compliance was calculated by dividing the number of survey sets completed by the number of eligible clinic visits. Compliance rates were further assessed by patient age, type of clinic visit, and location of injury. Costs associated with this system of routine PRO collection were categorized as start-up or maintenance costs. Results: From August 7, 2017, to December 8, 2017, there were 581 patients (1109 clinic encounters) who met inclusion criteria for the study. Of the 1109 clinic encounters, there was an overall compliance rate of 91.3% (1013/1109 visits during which the patient completed the entire PROMIS survey set). Overall, the full survey set consisted of a mean 15.3 questions and took a mean of 2.6 minutes to complete. Patients who were aged ≥62 years had a significantly lower compliance rate (81.8%; Conclusion: The routine electronic collection of PROMIS scores in the ambulatory orthopaedic clinic resulted in a compliance rate of over 90%, although older patients were generally less compliant than younger patients. Our system of data collection is practical and efficient in a high-volume orthopaedic clinic and places minimal financial burden on the provider

A cancer rainbow mouse for visualizing the functional genomics of oncogenic clonal expansion.

Field cancerization is a premalignant process marked by clones of oncogenic mutations spreading through the epithelium. The timescales of intestinal field cancerization can be variable and the mechanisms driving the rapid spread of oncogenic clones are unknown. Here we use a Cancer rainbow (Crainbow) modelling system for fluorescently barcoding somatic mutations and directly visualizing the clonal expansion and spread of oncogenes. Crainbow shows that mutations of ß-catenin (Ctnnb1) within the intestinal stem cell results in widespread expansion of oncogenes during perinatal development but not in adults. In contrast, mutations that extrinsically disrupt the stem cell microenvironment can spread in adult intestine without delay. We observe the rapid spread of premalignant clones in Crainbow mice expressing oncogenic Rspondin-3 (RSPO3), which occurs by increasing crypt fission and inhibiting crypt fixation. Crainbow modelling provides insight into how somatic mutations rapidly spread and a plausible mechanism for predetermining the intratumor heterogeneity found in colon cancers

Commentary driver training: effects of commentary exposure, practice and production on hazard perception and eye movements

Commentary driving typically involves being trained in how to produce a verbal running commentary about what you can see, what you are doing, what might happen and what action you will take to avoid potential hazards, while driving. Although video-based commentary training has been associated with subsequent hazard perception improvements, it can have a negative impact on hazard perception when a live commentary is produced at test (Young, Chapman, & Crundall, 2014). In the current study we use balanced training and testing blocks to isolate the effects of commentary exposure, production of a commentary with and without practice, and learning from earlier self-generation of commentary on behavioural and eye movement measures. Importantly, both commentary exposed and unexposed groups gave hazard perception responses during the commentary video, ensuring that the unexposed control group remained engaged in the procedure throughout. Results show that producing a live commentary is detrimental to concurrent hazard perception, even after practice, and does not enhance any later effect of commentary exposure. Although commentary exposure led to an initial increase in the accuracy of hazard perception responses, this effect was limited to the first occasion of testing, and showed no later benefits relative to engaged hazard exposure

Sleep deficits but no metabolic deficits in premanifest Huntington's disease.

OBJECTIVE: Huntington disease (HD) is a fatal autosomal dominant, neurodegenerative condition characterized by progressively worsening motor and nonmotor problems including cognitive and neuropsychiatric disturbances, along with sleep abnormalities and weight loss. However, it is not known whether sleep disturbances and metabolic abnormalities underlying the weight loss are present at a premanifest stage. METHODS: We performed a comprehensive sleep and metabolic study in 38 premanifest gene carrier individuals and 36 age- and sex-matched controls. The study consisted of 2 weeks of actigraphy at home, 2 nights of polysomnography and multiple sleep latency tests in the laboratory, and body composition assessment using dual energy x-ray absorptiometry scanning with energy expenditure measured over 10 days at home by doubly labeled water and for 36 hours in the laboratory by indirect calorimetry along with detailed cognitive and clinical assessments. We performed a principal component analyses across all measures within each studied domain. RESULTS: Compared to controls, premanifest gene carriers had more disrupted sleep, which was best characterized by a fragmented sleep profile. These abnormalities, as well as a theta power (4-7Hz) decrease in rapid eye movement sleep, were associated with disease burden score. Objectively measured sleep problems coincided with the development of cognitive, affective, and subtle motor deficits and were not associated with any metabolic alterations. INTERPRETATION: The results show that among the earliest abnormalities in premanifest HD is sleep disturbances. This raises questions as to where the pathology in HD begins and also whether it could drive some of the early features and even possibly the pathology.The study was funded from a grant from CHDI Foundation, Inc.CHDI-RG50786.

HIV Testing of At Risk Patients in a Large Integrated Health Care System

OBJECTIVE: Early identification of HIV infection is critical for patients to receive life-prolonging treatment and risk-reduction counseling. Understanding HIV screening practices and barriers to HIV testing is an important prelude to designing successful HIV screening programs. Our objective was to evaluate current practice patterns for identification of HIV. METHODS: We used a retrospective cohort analysis of 13,991 at-risk patients seen at 4 large Department of Veterans Affairs (VA) health-care systems. We also reviewed 1,100 medical records of tested patients. We assessed HIV testing rates among at-risk patients, the rationale for HIV testing, and predictors of HIV testing and of HIV infection. RESULTS: Of the 13,991 patients at risk for HIV, only 36% had been HIV-tested. The prevalence of HIV ranged from 1% to 20% among tested patients at the 4 sites. Approximately 90% of patients who were tested had a documented reason for testing. CONCLUSION: One-half to two-thirds of patients at risk for HIV had not been tested within our selected VA sites. Among tested patients, the rationale for HIV testing was well documented. Further testing of at-risk patients could clearly benefit patients who have unidentified HIV infection by providing earlier access to life-prolonging therapy

The Melanin-Concentrating Hormone (MCH) System Modulates Behaviors Associated with Psychiatric Disorders

Deficits in sensorimotor gating measured by prepulse inhibition (PPI) of the startle have been known as characteristics of patients with schizophrenia and related neuropsychiatric disorders. PPI disruption is thought to rely on the activity of the mesocorticolimbic dopaminergic system and is inhibited by most antipsychotic drugs. These drugs however act also at the nigrostriatal dopaminergic pathway and exert adverse locomotor responses. Finding a way to inhibit the mesocorticolimbic- without affecting the nigrostriatal-dopaminergic pathway may thus be beneficial to antipsychotic therapies. The melanin-concentrating hormone (MCH) system has been shown to modulate dopamine-related responses. Its receptor (MCH1R) is expressed at high levels in the mesocorticolimbic and not in the nigrostriatal dopaminergic pathways. Interestingly a genomic linkage study revealed significant associations between schizophrenia and markers located in the MCH1R gene locus. We hypothesize that the MCH system can selectively modulate the behavior associated with the mesocorticolimbic dopamine pathway. Using mice, we found that central administration of MCH potentiates apomorphine-induced PPI deficits. Using congenic rat lines that differ in their responses to PPI, we found that the rats that are susceptible to apomorphine (APO-SUS rats) and exhibit PPI deficits display higher MCH mRNA expression in the lateral hypothalamic region and that blocking the MCH system reverses their PPI deficits. On the other hand, in mice and rats, activation or inactivation of the MCH system does not affect stereotyped behaviors, dopamine-related responses that depend on the activity of the nigrostriatal pathway. Furthermore MCH does not affect dizocilpine-induced PPI deficit, a glutamate related response. Thus, our data present the MCH system as a regulator of sensorimotor gating, and provide a new rationale to understand the etiologies of schizophrenia and related psychiatric disorders
