Resurrecting Historical Observations to Characterize Species-Specific Nesting Traits of Bumblebees.

AbstractIn recent years, ecological research has become increasingly synthetic, relying on revolutionary changes in data availability and accessibility. In spite of their strengths, these approaches may cause us to overlook natural history knowledge that is not part of the digitized English-language scientific record. Here, we combine historic and modern documents to quantify species-specific nesting habitat associations of bumblebees (Bombus spp. Latreille, 1802 Apidae). We compiled nest location data from 316 documents, of which 81 were non-English and 93 were published before 1950. We tested whether nesting traits show phylogenetic signal, examined relationships between habitat associations at different scales, and compared methodologies used to locate nests. We found no clear phylogenetic signals, but we found that nesting habitat associations were somewhat generalizable within subgenera. Landcover associations were related to nesting substrate associations; for example, surface-nesting species also tended to be associated with grasslands. Methodology was associated with nest locations; community scientists were most likely and researchers using nest boxes were least likely to report nests in human-dominated environments. These patterns were not apparent in past syntheses based only on the modern digital record. Our findings highlight the tremendous value of historic accounts for quantifying species' traits and other basic biological knowledge needed to interpret global-scale patterns.

Patients' Use of a Standardized Medication List - A Mixed Methods Study.

Purpose: A medication list (ML) is a document listing the patient's entire medication, instructions for use, and indications. In Germany, a national standard was established in 2016 by law. However, data on patients' use of this standardized ML are scarce. We investigated (i) patients' practical use of the ML, (ii) patients' understanding of the ML, (iii) completeness and correctness of the current ML version, and (iv) reasons why patients did not adhere to their ML. Patients and Methods: Community pharmacists recruited patients possessing a standardized ML with ≥5 medications. Information sources to evaluate the ML were: (a) brown bag analysis, (b) practical demonstration, (c) patient interview, and (d) patient file. Data were analyzed using qualitative and quantitative methods. Results: Two hundred and eighty-eight patients (median age: 76 years, range: 27-95) were enrolled. (i) 38.5% of the patients used their ML regularly to prepare their medication and 73.3% to inform their physician. (ii) Overall, patients' understanding of the ML was good, with >80% of the patients being able to identify all relevant information. (iii) While n = 2779 medications were actually taken, n = 2539 were documented on the ML. No ML was fully correct and complete. Regarding particularly relevant items, ie, active ingredient, strength, dosage, medication missing or listed but not taken, 79.2% of ML were incorrect or incomplete. Handwritten modifications on the ML were frequent. (iv) Almost 60% of all patients did not follow their ML with "fear of adverse drug reactions" being the most frequently (n = 50) mentioned reason. Conclusion: Completeness and correctness of the current ML version was poor with handwritten modifications being frequent. Additionally, most of the patients did not adhere to their ML. This indicates that measures that lead to correct and up-to-date ML and improvements in patient counseling about their medication should be developed and implemented into routine practice.

Clinical pharmacy services are reimbursed in Germany: challenges of real world implementation remain.

Over the last two decades, community pharmacy has experienced major changes as the role of pharmacists is evolving from a product to a service and a patient focus. As part of this change, new and innovative clinical pharmacy services aimed at improving medicines use and patient outcomes have been designed, both nationally and internationally. Since June 2022, five services are reimbursed by all statutory health insurance funds and private insurance companies in Germany: medication review for patients with polymedication; blood pressure control in hypertension; assuring proper inhalation techniques for patients receiving a new device or a device change; medication review including a follow-up for patients taking oral anticancer drugs or immunosuppressants post-transplantation. Beyond reimbursement, the upscaling and sustainable provision of these professional services are now the main challenges. Implementation research will provide important information for the further development of pharmaceutical care programs.

Patients' perception on generating medication plans in an interprofessional medication management program: a mixed-methods study.

A medication plan (MP) provides an overview of a patient's entire medication. In the interprofessional medication management program ARMIN (ARzneiMittelINitiative Sachsen-Thueringen), MPs are jointly generated by general practitioners (GPs) and community pharmacists (CPs). We aimed to assess patients' initial acceptance of the service, how they use the printed MP, and whether they perceived a benefit from it. This was evaluated with mixed-methods: a cross sectional written (quantitative) survey followed by semi-structured (qualitative) interviews. The data were analysed separately and compared. Qualitative data were analysed by thematic analysis. For the survey, 103 patients (mean 73 years) were involved. Benefits indicated were: improved communication between GPs and CPs, safer handling of the medication, and increased knowledge on dosages and indications. Ninety-six percent of the patients used their MP, 51% regularly. Regular use was significantly associated with older age, higher number of drugs, and need for assistance with the medication. Ten patients were interviewed. Results from interviews agreed with the results from the survey but revealed some additional aspects (e.g., patients reported an increased feeling of safety). Health-care professionals should consider providing MPs for their patients. This interprofessional cooperation also meets patient's need for safety in health issues.

A meta-analysis of single visit pollination effectiveness comparing honeybees and other floral visitors.

PREMISE: Many animals provide ecosystem services in the form of pollination including honeybees, which have become globally dominant floral visitors. A rich literature documents considerable variation in single visit pollination effectiveness, but this literature has yet to be extensively synthesized to address whether honeybees are effective pollinators. METHODS: We conducted a hierarchical meta-analysis of 168 studies and extracted 1564 single visit effectiveness (SVE) measures for 240 plant species. We paired SVE data with visitation frequency data for 69 of these studies. We used these data to ask three questions: (1) Do honeybees (Apis mellifera) and other floral visitors differ in their SVE? (2) To what extent do plant and pollinator attributes predict differences in SVE between honeybees and other visitors? (3) Is there a correlation between visitation frequency and SVE? RESULTS: Honeybees were significantly less effective than the most effective non-honeybee pollinators but were as effective as the average pollinator. The type of pollinator moderated these effects. Honeybees were less effective compared to the most effective and average bird and bee pollinators but were as effective as other taxa. Visitation frequency and SVE were positively correlated, but this trend was largely driven by data from communities where honeybees were absent. CONCLUSIONS: Although high visitation frequencies make honeybees important pollinators, they were less effective than the average bee and rarely the most effective pollinator of the plants they visit. As such, honeybees may be imperfect substitutes for the loss of wild pollinators, and safeguarding pollination will benefit from conservation of non-honeybee taxa.

Exposure of Larvae of the Solitary Bee Osmia bicornis to the Honey Bee Pathogen Nosema ceranae Affects Life History.

Wild bees are important pollinators of wild plants and agricultural crops and they are threatened by several environmental stressors including emerging pathogens. Honey bees have been suggested as a potential source of pathogen spillover. One prevalent pathogen that has recently emerged as a honey bee disease is the microsporidian Nosema ceranae. While the impacts of N. ceranae in honey bees are well documented, virtually nothing is known about its effects in solitary wild bees. The solitary mason bee Osmia bicornis is a common pollinator in orchards and amenable to commercial management. Here, we experimentally exposed larvae of O. bicornis to food contaminated with N. ceranae and document spore presence during larval development. We measured mortality, growth parameters, and timing of pupation in a semi-field experiment. Hatched individuals were assessed for physiological state including fat body mass, wing muscle mass, and body size. We recorded higher mortality in the viable-spore-exposed group but could only detect a low number of spores among the individuals of this treatment. Viable-spore-treated individuals with higher head capsule width had a delayed pupation start. No impact on the physiological status could be detected in hatched imagines. Although we did not find overt evidence of O. bicornis infection, our findings indicate that exposure of larvae to viable N. ceranae spores could affect bee development.

[The PRIMA Project - Electronically-Supported Physician-Pharmacist Cooperation to Generate and Update Medication Plans in Germany]. / Das Projekt PRIMA ­ Elektronische Erstellung und Aktualisierung von Medikationsplänen als gemeinsame Aufgabe von Ärzten und Apothekern.

BACKGROUND: A complete overview on the patient's medication is one precondition for medication safety. For this, a complete and current medication plan (MP) is an appropriate instrument. We aimed to develop and implement software to evaluate and exchange medication plans in local software systems of general practitioners (GPs) and community pharmacies (CPs). Furthermore, it was the aim to evaluate feasibility and acceptance of the defined processes. METHODS: CPs and GPs were involved to pilot the software in several steps. Additionally, they generated and updated MP according to pre-defined processes and responsibilities. Feasibility and acceptance were evaluated in a survey and a workshop. RESULTS: For the first time in Germany, the technical requirements were established to generate and exchange MP electronically. Four software systems of CPs and one software system of GPs were involved. Solved Problems were technical errors, errors relevant for medication safety, differences in display of the medication data, and limited capacity of the barcode on the MP printout. Eleven GP and CP teams recruited 196 patients. 60 % were satisfied with the defined processes. 80 % of the GPs and 63 % of CPs agreed with the defined responsibilities. GPs considered the initial compilation on patient's medication in the CP as useful. The professional exchange between GPs and CPs improved: 70 % of GPs referred to increased knowledge on medication and 88 % of CPs received more information on patients' health conditions. The structured collaboration between GPs and CPs was considered to be important (25 %) or very important (75 %) for the quality of medication plans. DISCUSSION: An electronic MP was successfully implemented for the first time in local software systems. Processes and responsibilities were accepted by both professions. These are important prerequisites for sustainably implementing the MP in daily practice.

[Electronically supported co-operation of physicians and pharmacists to improve medication safety in the ambulatory setting : The "Arzneimittelinitiative Sachsen-Thüringen" (ARMIN)]. / Elektronisch unterstützte Kooperation ambulant tätiger Ärzte und Apotheker zur Verbesserung der Arzneimitteltherapiesicherheit : Die Arzneimittelinitiative Sachsen-Thüringen (ARMIN).

In Germany, the number of drugs dispensed, prescription as well as drugs that are sold without a prescription (over-the-counter drugs), is rising continuously. As a consequence, the proportion of patients with polymedication and the risk for adverse drug events is rising as well.The ABDA - Federal Union of German Associations of Pharmacists and the Federal Association of Statutory Health Insurance Physicians developed a comprehensive concept based on an interdisciplinary approach. Overall, the concept aims to improve both the effectiveness and safety of pharmacotherapy. The program consists of three components: (1) preferred generic prescribing (instead of brand name products), (2) preferred prescribing of first-line drugs according to a medication catalogue, and (3) medication management (MM). In ARMIN (Arzneimittelinitiative Sachsen-Thüringen), a contract signed in 2014, this concept was implemented for the first time.Datasets were developed and integrated into the local software of physicians and pharmacies to establish the prescription of active ingredients and dispensing the appropriate product as well as the medication catalogue. For MM, processes and responsibilities were developed as well as a technical infrastructure to enable an electronic exchange of patients' medication data.By December 2017, 546 physicians and 969 pharmacists participated in ARMIN, of which 297 physicians and 285 pharmacists were technically able to offer MM, and approximately 3200 patients had signed up for the MM service.In ARMIN, a promising interdisciplinary concept has been developed and implemented. Defining responsibilities and integrating the components into the local software of the physicians and pharmacists facilitated implementation. Future evaluation will show to what extent this concept can contribute to medication safety.

[Standardized national medication plan : The pilot projects MetropolMediplan 2016, model region Erfurt, and PRIMA]. / Der bundeseinheitliche Medikationsplan in der Praxis : Die Pilotprojekte MetropolMediplan 2016, Modellregion Erfurt und PRIMA.

Since 1 October 2016, all legally insured persons are entitled to a nationwide medication plan (BMP) under certain conditions (according to § 31a SGB V, E-Health Law). The catalogue of measures of the 3rd Action Plan 2013-2015 for the improvement of drug therapy safety (AMTS) provided for the testing of a medication plan in practice, including its acceptance and practicability in three model projects. These three projects - MetropolMediplan 2016, Erfurt, and PRIMA - are presented and recommendations are derived on the basis of the collected findings. Overall, the BMP was welcomed by the participating patients in all projects and led to an increase in satisfaction and an improvement in competence with regard to medication. Both doctors and pharmacists rated the interdisciplinary cooperation via the medium BMP very positively. The high effort and lack of technical infrastructure without electronic availability of the last current version of a BMP of the individual patient was perceived as negative. An original data comparison of the BMP data with the drugs actually taken in the MetropolMediplan 2016 project showed that only 36% of the patients were in agreement with the BMP and the drugs presently taken. The paper version of the BMP has therefore not yet been able to solve the problem of the timeliness and completeness of the medication. In addition to various proposals for the further development of BMP, all parties involved require the BMP to be available electronically across all sectors. The BMP should therefore be an important instrument for improving AMTS in the future.

[An Uncommon Cerebral Lesion in Computed Tomography]. / Ungewöhnliche zerebrale Läsion in der Computertomografie.

We report the case of a 84-year-old man who suffered a hematoma of the septum pellucidum due to a fall. The development of the septum pellucidum and its implications on pathomechanisms in head injury are discussed. In the setting of trauma, a reliable differentiation to other septal lesions can be impossible in computed tomography alone, unless earlier examinations are availabe for comparison. Additional magnetic resonance imaging may be warranted in case of vicinity of the lesion to the interventricular foramina.

Is there a role for conventional MRI and MR diffusion-weighted imaging for distinction of skull base chordoma and chondrosarcoma?

BACKGROUND: Chordoma and chondrosarcoma are locally invasive skull base tumors with similar clinical symptoms and anatomic imaging features as reported in the literature. PURPOSE: To determine differentiation of chordoma and chondrosarcoma of the skull base with conventional magnetic resonance imaging (cMRI) and diffusion-weighted MR imaging (DWI) in comparison to histopathological diagnosis. MATERIAL AND METHODS: This retrospective study comprised 96 (chordoma, n = 64; chondrosarcoma, n = 32) patients with skull base tumors referred to the Paul Scherrer Institute (PSI) for proton therapy. cMRI signal intensities of all tumors were investigated. In addition, median apparent diffusion coefficient (ADC) values were measured in a subgroup of 19 patients (chordoma, n = 11; chondrosarcoma, n = 8). RESULTS: The majority 81.2% (26/32) of chondrosarcomas displayed an off-midline growth pattern, 18.8% (6/32) showed clival invasion, 18.8% (6/32) were located more centrally. Only 4.7% (3/64) of chordomas revealed a lateral clival origin. Using cMRI no significant differences in MR signal intensities were observed in contrast to significantly different ADC values (subgroup of 19/96 patients examined by DWI), with the highest mean value of 2017.2 × 10(-6 )mm(2)/s (SD, 139.9( )mm(2)/s) for chondrosarcoma and significantly lower value of 1263.5 × 10(-6 )mm(2)/s (SD, 100.2 × 10(-6 )mm(2)/s) for chordoma (P = 0.001/median test). CONCLUSION: An off-midline growth pattern can differentiate chondrosarcoma from chordoma on cMRI in a majority of patients. Additional DWI is a promising tool for the differentiation of these skull base tumors.

Cationic Peptides Facilitate Iron-induced Mutagenesis in Bacteria.

Pseudomonas aeruginosa is the causative agent of chronic respiratory infections and is an important pathogen of cystic fibrosis patients. Adaptive mutations play an essential role for antimicrobial resistance and persistence. The factors that contribute to bacterial mutagenesis in this environment are not clear. Recently it has been proposed that cationic antimicrobial peptides such as LL-37 could act as mutagens in P. aeruginosa. Here we provide experimental evidence that mutagenesis is the product of a joint action of LL-37 and free iron. By estimating mutation rate, mutant frequencies and assessing mutational spectra in P. aeruginosa treated either with LL-37, iron or a combination of both we demonstrate that mutation rate and mutant frequency were increased only when free iron and LL-37 were present simultaneously. Colistin had the same effect. The addition of an iron chelator completely abolished this mutagenic effect, suggesting that LL-37 enables iron to enter the cells resulting in DNA damage by Fenton reactions. This was also supported by the observation that the mutational spectrum of the bacteria under LL-37-iron regime showed one of the characteristic Fenton reaction fingerprints: C to T transitions. Free iron concentration in nature and within hosts is kept at a very low level, but the situation in infected lungs of cystic fibrosis patients is different. Intermittent bleeding and damage to the epithelial cells in lungs may contribute to the release of free iron that in turn leads to generation of reactive oxygen species and deterioration of the respiratory tract, making it more susceptible to the infection.

The Evonik-Mainz-Eye-Care-Study (EMECS): design and execution of the screening investigation.

PURPOSE: To determine if screening for major ophthalmological diseases is feasible within the frame of routine occupational medicine examinations in a large working population. METHODS: 13037 employees of Evonik Industries aged 40 to 65 years were invited to be screened for major ophthalmological diseases (glaucoma, age related macular degeneration and diabetic retinopathy between June 2007 and March 2008 within an extended setting of occupational medicine. Ophthalmological examinations consisted of visual acuity, objective refraction, pachymetry, tonometry, perimetry (frequency doubling technology), confocal scanning laser ophthalmoscopy and digital fundus photography. Participants responded to a questionnaire addressing history of ocular and general diseases and social history. RESULTS: 4183 participants (961 female and 3222 male) were examined at 13 different sites. Response rates for eligible persons at those sites ranged from 17.9 to 60.5% but were in part limited by availability of examination slots. Average age of participants was 48.4 ± 5.4 years (mean ± SD). 4147 out of 4183 subjects (99.1%) had a visual acuity ≥ 0.5 in the better eye and 3665 out of 4183 (87.6%) subjects had a visual acuity ≥ 0.8 in the better eye. 1629 participants (38.9%) had previously not been seen by an ophthalmologist at all or not within the last three years. CONCLUSION: This article describes the study design and basic characteristics of study participants within a large occupational medicine based screening study for ophthalmological diseases. Response rates exceeded expectations and were limiting examination capacity. Meaningful data could be obtained for almost all participants. We reached participants who previously had not received ophthalmic care. Thus, ophthalmological screening appears to be feasible within the frame of routine occupational medicine examinations.

Pharmacist-led intervention study to improve inhalation technique in asthma and COPD patients.

UNLABELLED: RATIONAL AND AIMS: Inhaled therapy is the mainstay of treatment in patients with asthma and chronic obstructive pulmonary disease (COPD). For effectiveness of pharmacotherapy, correct use of medication is required. The aims of this study were to survey the quality of inhalation technique in patients and to determine the effect of a single intervention in community pharmacies by means of standardized procedures. METHODS: A total of 757 patients with asthma or COPD were randomly selected by 55 community pharmacies. At baseline, patients were interviewed and their inhalation technique was assessed with a 21-items checklist. Any error was recorded and, if necessary, patients were instructed in the proper use of their device. After 4-6 weeks, demonstration of inhalation technique was repeated in the community pharmacies and a pre-post comparison was performed. RESULTS: A total of 597 patients (78.9%) made at least one mistake in performing the inhalation technique at baseline. This number dropped to 214 (28.3%) from the first to the second appointment. All patients did benefit from the pharmacists' intervention regardless of their former training experiences. CONCLUSIONS: Inhalation technique of asthma and COPD patients is poor. In daily practice, community pharmacy-based pharmacists are well suited to significantly supplement doctor-based education in inhalation technique.

[Involving pharmacists in the management of asthma patients]. / Versorgungsmanagement für Menschen mit Asthma--Einbindung der Apotheker.

Several national and international studies on the care of asthma patients delivered by community pharmacists have shown that pharmacist interventions help to improve patient parameters like, for example, the patient's quality of life, self-management skills, compliance and optimization of drug therapy. These results have led to pharmacists' involvement in national asthma guidelines, e.g., in the UK and the United States. Pharmacists have now also been involved in the revised version of the German national guidelines on asthma. In this paper we will present the existing evidence in Germany on how pharmacists add value to the care of asthma patients. Furthermore, the involvement of pharmacists in the German National Disease Management Guideline for Asthma will be discussed.

Shift work, chronodisruption and cancer?--The IARC 2007 challenge for research and prevention and 10 theses from the Cologne Colloquium 2008.

In October of 2007, an IARC panel of 24 scientists systematically evaluated epidemiologic, experimental, and mechanistic data and concluded that shift work that involves circadian or chronodisruption is probably carcinogenic in humans. In view of the possible scope of the problem--shift work is widespread and unavoidable on one hand and breast cancer and prostate cancer, which may be causally associated with chronodisruption, are epidemic worldwide on the other--German representatives of science and occupational medicine discussed the experimental and epidemiologic background and possible implications of the challenge identified by the International Agency for Research on Cancer (IARC) at a colloquium in Cologne in September 2008. This overview summarizes the key ideas presented at the Cologne Colloquium and offers 10 theses concerning the need for targeted studies and the necessity to develop possible means of prevention.

[Prevention of type 2 diabetes in Germany--a challenge for health professionals]. / Prävention des Diabetes mellitus in Deutschland. Herausforderung für die Gesundheitsberufe.

The most efficient way to manage diabetes and its complications is to prevent diabetes. Recent studies have convincingly demonstrated that prevention of diabetes and its complications are possible and cost effective. Life-style interventions and also early pharmacological preventive strategies have yielded a 25-75% diabetes risk reduction and an even more promising reduction in cardiovascular risks. These findings offer the evidence-base for diabetes prevention, but essential is the delivery of intervention into our societies. The challenge, therefore, is the management of prevention and intervention programs considering scientific aspects and practical requirements during implementation. This can only be addressed in a coordinated interdisciplinary setting and across sectors which requires the development of a comprehensive, integrated prevention management program also on an European level. Pharmacies have to play an important role in this concept because of their widespread distribution and the frequency of pharmacy visits of the general population. They should be established as places where patients can continuously offer risk assessment including recommendations on how to prevent the disease. Developing the role of the prevention manager and continuous evaluation and quality control are key factors in performing high quality intervention and care. Community pharmacies could take an active part in this prevention program, its evaluation, and quality assurance. Implementing structured prevention programs will enable nationwide prevention of diabetes mellitus without consuming large resources from health care insurances. This process will be challenging and time consuming, requiring many partners but resulting in a profitable "health" investment.
