Collaboration of general practitioners and gynaecologists in outpatient health care for women aged 50 and over in Germany
Hintergrund
Die Frauengesundheit von Ă€lteren Frauen ist vor allem in lĂ€ndlichen Gebieten Deutschlands vor dem Hintergrund einer steigenden Anzahl von Frauen ab 50 Jahren und einer drohenden Unterversorgung bei medizinischen Leistungen zu betrachten. EinflĂŒsse auf die PrimĂ€rversorgung wie Delegation, Telemedizin oder interdisziplinĂ€re Praktiken wurden in Studien beschrieben. Zu interdisziplinĂ€ren Praktiken zĂ€hlen Vernetzung und Zusammenarbeit von FachĂ€rztinnen/FachĂ€rzten (FĂ) in der ambulanten PrimĂ€rversorgung. In Bezug auf die Gesundheit Ă€lterer Frauen berichteten HausĂ€rztinnen/HausĂ€rzte (HĂ) sowie GynĂ€kologinnen/GynĂ€kologen (Gyn) als zustĂ€ndige FĂ-Gruppen in dieser Arbeit ĂŒber die Versorgungssituation sowie ĂŒber ihre Vernetzung und Zusammenarbeit. DarĂŒber hinaus wurden Einflussfaktoren auf die Zusammenarbeit wissenschaftlich untersucht.
Methodik
Zwischen MĂ€rz und Juni 2018 wurde im Stadtstaat Berlin sowie in den FlĂ€chenlĂ€ndern Brandenburg und Mecklenburg-Vorpommern im Rahmen einer reprĂ€sentativen postalischen Befragung eine randomisierte Auswahl von 3.514 HĂ (67 % von 5.265 HĂ) und 1.031 Gyn in einer Vollerhebung quantitativ unter Verwendung eines selbst entwickelten und mit Expertinnen/Experten pilotierten Fragebogens befragt. Deskriptive Analysen wurden zur Darstellung von Versorgungssituation, formeller und informeller Vernetzung sowie zu 13 Aspekten der Zusammenarbeit genutzt. Die Ermittlung von Einflussfaktoren auf die Zusammenarbeit erfolgte jeweils mittels multipler logistischer Regressionen, adjustiert nach Alter und Geschlecht.
Ergebnisse
Der Fragebogen wurde von 1.389 FĂ (861 HĂ, 528 Gyn) ausgefĂŒllt zurĂŒckgesendet, was einer Responserate von 31 % (25 % HĂ, 51 % Gyn) entsprach. Responder waren im Durchschnitt 54,4 Jahre alt, eher weiblich (72 %) und stammten aus den FlĂ€chenlĂ€ndern (55 %). Die gynĂ€kologische Versorgungssituation wird von 30 % aller Responder als bedroht angesehen. Insgesamt gaben 68 % der FĂ an vernetzt zu sein, jedoch nur 10 % in formalen Strukturen. Haupteinflussfaktoren auf die engere Zusammenarbeit von HĂ und Gyn war das Praktizieren in einem FlĂ€chenland sowie die Angabe, Teil eines Netzwerks zu sein. So war die Zufriedenheit mit der Zusammenarbeit in FlĂ€chenlĂ€ndern höher als im Stadtstaat (Odds Ratio [OR] = 1,7, 95 %iges Konfidenzintervall [CI] = 1,3-2,1) sowie bei HĂ und Gyn als Teil eines informellen Netzwerks im Vergleich mit HĂ und Gyn ohne informelles Netzwerk (OR = 2,7, CI = 2,1-3,4).
Schlussfolgerungen
Die Versorgungssituation wird in FlĂ€chenlĂ€ndern und Stadtstaat im gleichen MaĂe als bedroht angesehen. Zusammenarbeit ist systematisch besser ausgeprĂ€gt zwischen ambulant tĂ€tigen HĂ und Gyn in FlĂ€chenlĂ€ndern sowie zwischen FĂ, die sich einem Netzwerk zugehörig fĂŒhlen. Eine stĂ€rkere informelle und formale Vernetzung könnte die Zusammenarbeit zwischen HĂ und Gyn verbessern, die KontinuitĂ€t und Sicherheit der ambulanten Ă€rztlichen Versorgung Ă€lterer Frauen steigern und die Zufriedenheit der FĂ stĂ€rken.Background
The health of elderly women, especially in rural areas of Germany, has to be considered within the context of an increasing number of women aged 50 and over and a threatening shortage of medical services. Influences on the primary healthcare such as delegation, telemedicine or interdisciplinary practices have been described in previous studies. Interdisciplinary practices include networking and collaboration between medical specialists in outpatient primary healthcare. Being the responsible medical specialists in this study, general practitioners (GPs) and gynaecologists (Gyns) reported on the healthcare situation as well as on their networking and collaboration. In addition, factors influencing these collaborations were scientifically investigated.
Methods
Between March and June 2018, a randomised selection of 3,514 GPs (67 % of 5,265 GPs) and 1,031 Gyns from the city state of Berlin and the territorial states of Brandenburg and Mecklenburg-Western Pomerania were surveyed quantitatively with a representative postal survey using a self-developed questionnaire, which was pilot-tested with the help of experts. Descriptive analyses were used to describe the healthcare situation, formal and informal networking and 13 aspects of the collaboration among GPs and Gyns. Factors influencing collaboration were determined using multiple logistic regressions, adjusted for age and gender.
Results
The questionnaire was completed and returned by 1,389 physicians (861 GPs, 528 Gyns), which corresponded to a response rate of 31 % (25 % GPs, 51 % Gyns). Responders were on average 54.4 years old, more likely to be female (72 %) and working in the territorial states (55 %). The gynaecological care situation was considered threatened by 30 % of all responders. Overall, 68 % of the Gyns stated that they were members of a network, but only 10 % in formal structures. The main factors influencing a closer collaboration between GPs and Gyns included practising in a territorial state and being member of a network. Satisfaction regarding collaboration was higher in territorial states than in the city state (odds ratio [OR] = 1.7, 95 % confidence interval [CI] = 1.3-2.1) and for GPs and Gyns that were members of an informal network compared to those GPs and Gyns without an informal network (OR = 2.7, CI = 2.1-3.4).
Conclusions
The healthcare situation is considered to be threatened to the same extent in the territorial states and the city state. Collaboration is systematically better developed between outpatient GPs and Gyns in the territorial states and between those who see themselves as members of a network. Stronger informal and formal networking could improve collaboration between GPs and Gyns, increase the continuity and safety of outpatient medical care for elderly women and increase the satisfaction of the specialists
Support for General Practitioners in the Care of Patients with Complex Needs: A Questionnaire Survey of General Practitioners in Berlin
OBJECTIVES
Because of demographic changes, new models of care are important for supporting general practitioners in the care of patients with complex needs. This study addresses the question of the type of support that is requested by general practitioners working in Berlin.
METHODS
All general practitioners working in Berlin (n=2354) were asked between August and September 2018 to return a questionnaire by post which has been developed for this study. Questions addressed support needs as well as support models within the practice (delegation, substitution) and outside the practice (social worker, navigator, community care points). Data were analysed descriptively and by exploratory multivariate analysis to show the influence of practice and doctor characteristics on the preference of support models (age, gender, location of the practice, type of practice, working hours).
RESULTS
A total of 557 questionnaires (response rate 23.7%) were included in the analysis. Need for support was seen particularly for administrative, coordinative and organisational tasks and for advice on social issues. The majority of the study participants approved delegation and substitution. In their view, it was conceivable to get support from professionals or institutions outside their practice, such as mobile care services, community care points, social workers or navigators. Particularly younger and female doctors working in group practices were open for cooperative care models integrating other health professions.
CONCLUSIONS
There is unused potential for delegation and cooperation within existing structures. Further research should investigate the acceptance and feasibility of different support models.ZIEL
Vor dem Hintergrund der demografischen Entwicklung werden zukĂŒnftig Versorgungsmodelle wichtig, die HausĂ€rzte in der Versorgung von Patienten mit komplexem Bedarf unterstĂŒtzen können. Die vorliegende Fragebogenstudie untersucht, welche Formen der UnterstĂŒtzung sich Berliner HausĂ€rzte wĂŒnschen.
METHODIK
Alle niedergelassenen HausĂ€rzte Berlins (n=2354) wurden im Zeitraum August bis September 2018 postalisch gebeten, einen fĂŒr die Fragestellung entwickelten Fragebogen auszufĂŒllen. Die Fragen adressierten den UnterstĂŒtzungsbedarf sowie verschiedene UnterstĂŒtzungsmodelle. Es wurde zwischen UnterstĂŒtzungsmöglichkeiten innerhalb (Delegation, Substitution) und auĂerhalb (Sozialarbeiter, Versorgungslotsen, PflegestĂŒtzpunkt) von Hausarztpraxen differenziert. Die Auswertung erfolgte deskriptiv, sowie explorativ multivariat in Bezug auf ZusammenhĂ€nge zwischen der Zustimmung zu UnterstĂŒtzungsmodellen und Praxis- bzw. Arztcharakteristika (Alter, Geschlecht der Ărzte, Lage der Praxis, Praxisform, Arbeitszeit).
ERGEBNISSE
557 Fragebögen (Response Rate 23,7%) wurden ausgewertet. UnterstĂŒtzungsbedarf wurde v.âa. fĂŒr administrative, koordinative und organisatorische TĂ€tigkeiten gesehen sowie fĂŒr soziale und sozialrechtliche Fragestellungen. Ein GroĂteil der teilnehmenden hausĂ€rztlichen Praxen steht sowohl der Delegation als auch der Substitution Ă€rztlicher Leistungen positiv gegenĂŒber. DarĂŒber hinaus ist fĂŒr HausĂ€rzte auch UnterstĂŒtzung auĂerhalb der eigenen Praxis durch Mitarbeiter eines ambulanten Pflegedienstes, eines PflegestĂŒtzpunktes, oder durch Sozialarbeiter und Versorgungslotsen vorstellbar. Insbesondere jĂŒngere und weibliche HausĂ€rzte sowie diejenigen, die bereits in kooperativen Praxis-Strukturen tĂ€tig sind, sind offen fĂŒr kooperative AnsĂ€tze unter Einbeziehung weiterer Gesundheitsberufe.
SCHLUSSFOLGERUNG
Es bestehen noch unzureichend genutzte Potenziale der Delegation und der Kooperation mit bestehenden Strukturen. Die hier befragten Berliner HausĂ€rzte zeigten ein hohes MaĂ an Zustimmung zu Delegation und Substitution. Aber auch Gesundheitsberufe und Institutionen auĂerhalb der eigenen Praxis könnten die HausĂ€rzte stĂ€rker unterstĂŒtzen. Insbesondere fĂŒr administrative und koordinative TĂ€tigkeiten sowie fĂŒr soziale und sozialrechtliche Fragestellungen wird UnterstĂŒtzungsbedarf gesehen. In weiteren Untersuchungen sollte die Akzeptanz unter der Ărzteschaft und die Machbarkeit unterschiedlicher Modelle weiter untersucht werden
Stereotypical Chronic Lymphocytic Leukemia B-Cell Receptors Recognize Survival Promoting Antigens on Stromal Cells
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world. Survival of CLL cells depends on their close contact with stromal cells in lymphatic tissues, bone marrow and blood. This microenvironmental regulation of CLL cell survival involves the stromal secretion of chemo- and cytokines as well as the expression of adhesion molecules. Since CLL survival may also be driven by antigenic stimulation through the B-cell antigen receptor (BCR), we explored the hypothesis that these processes may be linked to each other. We tested if stromal cells could serve as an antigen reservoir for CLL cells, thus promoting CLL cell survival by stimulation through the BCR. As a proof of principle, we found that two CLL BCRs with a common stereotyped heavy chain complementarity-determining region 3 (previously characterized as âsubset 1â) recognize antigens highly expressed in stromal cells â vimentin and calreticulin. Both antigens are well-documented targets of autoantibodies in autoimmune disorders. We demonstrated that vimentin is displayed on the surface of viable stromal cells and that it is present and bound by the stereotyped CLL BCR in CLL-stroma co-culture supernatant. Blocking the vimentin antigen by recombinant soluble CLL BCR under CLL-stromal cell co-culture conditions reduces stroma-mediated anti-apoptotic effects by 20â45%. We therefore conclude that CLL BCR stimulation by stroma-derived antigens can contribute to the protective effect that the stroma exerts on CLL cells. This finding sheds a new light on the understanding of the pathobiology of this so far mostly incurable disease
Collaboration amongst general practitioners and gynaecologists working in primary health care in Germany: a cross-sectional study
Aim: This cross-sectional study is the first one to explore the collaboration of the influencing factors thereof amongst general practitioners (GPs) and gynaecologists (Gyns) working in primary care in urban and rural settings in Germany.
Background: The number of women aged >= 50 years is predicted to increase in the next years in Germany. This coincides with the ageing of primary care specialists providing outpatient care. Whereas delegation of tasks to nurses as a form of interprofessional collaboration has been the target of recent studies, there is no data regarding collaboration amongst physicians in different specialisations working in primary care. We explored collaboration amongst GPs and Gyn regarding the healthcare provision to women aged >= 50 years.
Methods: A quantitative postal survey was administered to GPs and Gyns in three federal states in Germany, focusing on care provision to women aged >= 50 years. A total of 4545 physicians, comprising 3514 GPs (67% of the total GP population) randomly selected, and all 1031 Gyns practicing in these states received the postal survey in March 2018. A single reminder was sent in April 2018 with data collection ending in June 2018. Multiple logistic regressions were performed for collaboration, adjusted by age and sex, alongside descriptive methods.
Findings: The overall response rate was 31% (1389 respondents): 861 GPs (25%) and 528 Gyns (51%), with the mean respondent age being 54.4 years. Seventy-two per cent were female. Key competencies of collaboration are associated with working in rural federal states and with network participation. Physicians from rural states [odds ratio (OR) = 1.5, 95% confidence interval (CI) = 1.2, 1.9] and physicians in networks (OR = 3.0, CI = 2.3, 3.9) were more satisfied with collaboration. Collaboration to deliver services for women aged >= 50 years is more systematic amongst GPs and Gyns who are members of a network; increased networking could improve collaboration, and ultimately, outcomes too

Chaxapeptin, a Lasso Peptide from ExtremotolerantStreptomyces leeuwenhoekiiStrain C58 from the Hyperarid Atacama Desert.
Lasso peptides are ribosomally synthesized and post-translationally modified peptides (RiPPs) that possess a unique âlariat knotâ structural motif. Genome mining-targeted discovery of new natural products from microbes obtained from extreme environments has led to the identification of a gene cluster directing the biosynthesis of a new lasso peptide, designated as chaxapeptin 1, in the genome of Streptomyces leeuwenhoekii strain C58 isolated from the Atacama Desert. Subsequently, 1 was isolated and characterized using high-resolution electrospray ionization mass spectrometry and nuclear magnetic resonance methods. The lasso nature of 1 was confirmed by calculating its nuclear Overhauser effect restraint-based solution structure. Chaxapeptin 1 displayed a significant inhibitory activity in a cell invasion assay with human lung cancer cell line A549
