Intervention for sleep problems in nursing home residents with dementia: a cluster-randomized study.

OBJECTIVE: To reduce sleep problems in people living with dementia using a multi-component intervention. DESIGN: Cluster-randomized controlled study with two parallel groups and a follow-up of 16 weeks. SETTING: Using external concealed randomization, 24 nursing homes (NH) were allocated either to the intervention group (IG, 12 clusters, 126 participants) or the control group (12 clusters, 116 participants). PARTICIPANTS: Participants were eligible if they had dementia or severe cognitive impairment, at least two sleep problems, and residence of at least two weeks in a NH. INTERVENTION: The 16-week intervention consists of six components: (1) assessment of sleep-promoting activities and environmental factors in NHs, (2) implementation of two "sleep nurses," (3) basic education, (4) advanced education for staff, (5) workshops to develop sleep-promoting concepts, and (6) written information and education materials. The control group (CG) received standard care. MEASUREMENTS: Primary outcome was ≥ two sleep problems after 16 weeks assessed with the Sleep Disorders Inventory (SDI). RESULTS: Twenty-two clusters (IG = 10, CG = 12) with 191 participants completed the study. At baseline, 90% of people living with dementia in the IG and 93% in the CG had at least two sleep problems. After 16 weeks, rates were 59.3% (IG) vs 83.8% (CG), respectively, a difference of -24.5% (95% CI, -46.3% - -2.7%; cluster-adjusted odds ratio 0.281; 95% CI 0.087-0.909). Secondary outcomes showed a significant difference only for SDI scores after eight and 16 weeks. CONCLUSIONS: The MoNoPol-Sleep intervention reduced sleep problems of people living with dementia in NH compared to standard care.

Item distribution, internal consistency and structural validity of the German language person-centred climate questionnaire - staff version (PCQ-G-S): a cross-sectional study.

BACKGROUND: Person-centredness is considered as best practice for people living with dementia. A frequently used instrument to assess person-centredness of a care environment is the Person-centred Climate Questionnaire (PCQ). The questionnaire comprises of 14 items with the three subscales a climate of safety, a climate of everydayness and a climate of community. AIM: The aim of the study is to describe the translation process of the English language Person-centred Climate Questionnaire (Staff version, Patient version, Family version) into German language (PCQ-G) and to evaluate the first psychometric properties of the German language Person-centred Climate Questionnaire- Staff version (PCQ-G-S). METHODS: We conducted a cross-sectional study. The three versions of the 14-item English PCQ were translated into German language (PCQ-G) based on the recommendations for cross-cultural adaption of measures. Item distribution, internal consistency and structural validity of the questionnaire were assessed among nursing home staff (PCQ-G-S). Item distribution was calculated using descriptive statistics. Structural validity was tested using principal component analysis (PCA), and internal consistency was assessed for the resulting subscales using Cronbach's alpha. Data collection took place from May to September 2021. RESULTS: A total sample of 120 nurses was included in the data analysis. Nine out of 14 items of the PCQ-G-S demonstrated acceptable item difficulty, while five times showed a ceiling effect. The PCA analysis demonstrated a strong structural validity for a three-factor solution explaining 68.6% of the total variance. The three subscales demonstrated a good internal consistency with Cronbach's alpha scores of 0.8 for each of the subscales. CONCLUSION: The analysis of the 14-item German version (PCQ-G-S) showed first evidence for a strong internal consistency and structural validity for evaluating staff perceptions of the person-centredness in German nursing homes. Based on this, further investigations for scale validity of the PCQ-G versions should be carried out.

[Structured case conference for sleep disturbances in nursing home residents with cognitive impairment]. / Strukturierte Fallbesprechung bei Schlafproblemen von Pflegeheimbewohner_innen mit kognitiven Einschränkungen.

Structured case conference for sleep disturbances in nursing home residents with cognitive impairment Abstract: Background: Nursing home residents living with cognitive impairment often suffer from sleep disturbances. Pharmacological interventions are not recommended to be the first-choice therapy. In general, a wide variance of non-pharmacological interventions is available, but no clearly suitable intervention can currently be specified. Aim: The case report presents the procedure of a structured analysis to support the selection of non-pharmacological interventions to promote sleep. Methods: A structured case conference was held using a developed case management template to draw up an individual intervention plan. Results: Based on the description of the situation and the determination of causes, different interventions from six main topics were planned: "offering appropriate activations during daytime", "creating bedtime routines", "checking the sleep environment", "observation of potential physical and psychological causes", "reflection on night care routines", and "use of drug therapies only in exceptional cases". Conclusions: For a successful management of sleep disturbances in nursing home residents living with cognitive impairment, it is essential that the specific sleep-related symptoms and causes are assessed systematically and interprofessionally to be able to work towards an improvement with appropriate measures. In order to obtain adequate solutions, evidence-based expertise should be taken into consideration.

Attitudes and knowledge of nurses working at night and sleep promotion in nursing home residents: multicenter cross-sectional survey.

BACKGROUND: Sleep disturbances are common in nursing home residents and challenging for their nurses. Knowledge about sleep and sleep promoting factors is essential to provide adequate sleep management, where nurses play a key role. Therefore, nurses' knowledge and attitudes towards sleep and sleep promoting interventions is important as enabling or inhibiting factor for successful sleep management. METHODS: A multicenter cross-sectional study was conducted among nurses working wholly or partially at night in nursing homes in Germany. Data were collected between February and April 2021 via online or paper and pencil questionnaires, comprising 56 items. Nursing homes were recruited through existing cooperation with the study centers as well as via nursing home registers. RESULTS: Finally, 138 nursing homes participated and 271 nurses completed the survey. Nurses agreed that sleep disturbances are an important topic with important impact on resident' health. Although, the assessment of sleep was seen as nurses' responsibility, only 40 nurses (14.7%) stated that residents' sleep was always documented. Only 21.7% reported the availability of policy documents providing guidance regarding the management of sleep disturbances. The vast majority (93.2%) reported never having received training about sleep and management of sleep disturbances after their basic nursing training. CONCLUSIONS: Our results indicate that nurses working at night can play an important role in residents' sleep promotion. The findings indicate nurses' educational needs regarding sleep and sleep promotion. Nursing homes should implement institutional guidelines in order to promote residents' sleep based on adequate evidence-based non-pharmacological interventions.

[Dementia Care Nurse - Feasibility study of outreach assistance for people with dementia and their family carers]. / Dementia Care Nurse.

Dementia Care Nurse - Feasibility study of outreach assistance for people with dementia and their family carers Abstract. Background: Case management for dementia is stipulated in the German national dementia strategy. The effectiveness of case management has been investigated many times, yet the results are heterogeneous. On the contrary, the implementation processes of case management concepts have to date rarely been described or evaluated in detail. Aim: The aim of the project was to analyze the implementation of an outreaching assistance for people with dementia and to explore the changes in care, acceptance, and also facilitators and barriers to the implementation. Methods: Between 08 / 2018 and 07 / 2019, outreaching assistance for people with dementia and their family carers was implemented. Quantitative and qualitative data were prospectively collected using semi-standardised interviews in the context of outreach assistance. Results: A total of 113 people with dementia were included in the study, and for the most part family carers could be involved. On average, eight contacts took place over a period of 74 days. The areas of need and support were diverse. The use of support services increased by 19 % after the end of the intervention. Conclusions: The implementation of continuous and processual support for people with dementia and their carers is possible, whereby the structure and procedure should be transparent. A comprehensive orientation and networking is beneficial. The effectiveness of the intervention remains to be investigated in a controlled study.

[Challenges in dementia care at home - The situation at home of a married couple]. / Herausforderungen bei Demenz in den eigenen vier Wänden.

Challenges in dementia care at home - The situation at home of a married couple Abstract. Background: People with dementia and their relatives are faced with major challenges due to complex dementia symptoms. Families need information and counselling in order to find adequate dementia care services tailored to their needs. AIM: This case report's objective is to exemplify the domestic situation of a married couple who is faced with significant challenges within the family and the care system due to the husband's dementia and Parkinson's disease. METHODS: The Dementia Care Nurse project included case monitoring; by means of different assessments relevant information was recorded and the family's situation described. RESULTS: The family's problems and their need for support were multifaceted and entailed reimbursement of costs, application for care services as well as management of challenging behaviours and reduction of the caregiver's psychosocial burden. CONCLUSIONS: The family, particularly the spouse caregiver, was effectively supported in meeting the challenges of dementia, e. g. by drawing on professional services and sorting out entitlement to benefits. From the perspective of the experience in the project, independent counselling structures such as a case management approach are indispenable in order to stabilise the domestic situation.

Die Lebenssituation von Menschen mit Demenz und pflegenden Angehörigen während der Coronavirus-Pandemie Eine qualitative Studie.

The life situation of people with dementia and family carers during the coronavirus pandemic - A qualitative study Abstract. Background: The measures initiated as a result of the coronavirus pandemic have far-reaching consequences for the everyday life of people with dementia and their family carers. Both are usually among those who are the most vulnerable and thus are subject to rigorous restrictions. Their everyday life is made more difficult because care and respite services are currently suspended. In addition, people with dementia have difficulty understanding and implementing the restrictions and hygiene rules. AIMS: This study aims to describe the current life situation of family carers and people with dementia. METHODS: For this purpose, 21 telephone interviews with both family carers and people with dementia have been conducted twice during the spring of 2020 and were subsequently evaluated by a content analysis. RESULTS: The interviewees experienced the situation differently. Especially the social isolation, the higher amount of care, the uncertainty of the situation and the increase in psychological symptoms are described as being stressful. With regard to coping with the situation, discussions are taking place about the support from the social environment, alternative ways of communication, experiences with comparable crises, the stability of formal care and the handling of information. CONCLUSIONS: Family carers and people with dementia feel stressed due to the coronavirus pandemic, but many of them have coping strategies for this special situation. Informal support is a particularly important support mechanism.

Preparation and Regioselective Magnesiation or Lithiation of Bis(trimethylsilyl)methyl-Substituted Heteroaryls for the Generation of Highly Functionalized Heterocycles.

A wide range of bis(trimethylsilyl)methyl (BTSM)- substituted heteroaryl derivatives has been prepared by using Kumada-Corriu or Negishi cross-coupling reactions. The regioselective lithiation or magnesiation of these building blocks bearing a bulky BTSM group by using magnesium or lithium 2,2,6,6-tetramethylpiperidide bases followed by quenching reactions with different electrophiles provides various functionalized N-, O-, or S-heterocycles. Furthermore, the BTSM group can then be converted into formyl, methyl, or styryl groups to give access to a variety of highly functionalized heteroaromatics.

Preparation and regioselective metalation of bis(trimethylsilyl)methyl-substituted aryl derivatives.

A range of bis(trimethylsilyl)methyl-substituted aryl derivatives was prepared by using a Kumada-Corriu cross-coupling reaction. The regioselective metalation of the resulting bis(trimethylsilyl)methyl-substituted aryl derivatives bearing this bulky silyl group allowed the generation of functionalized aromatics. A regioselective switch in the presence or in the absence of the bis(trimethylsilyl)methyl group has been demonstrated. Furthermore, this silyl group was converted into a formyl group or a styryl group, enhancing the scope of application of such bis(trimethylsilyl)methyl-substituted arenes.

Strategies to prepare and use functionalized organometallic reagents.

Polyfunctional zinc and magnesium organometallic reagents occupy a central position in organic synthesis. Most organic functional groups are tolerated by zinc organometallic reagents, and Csp(2)-centered magnesium organometallic reagents are compatible with important functional groups, such as the ester, aryl ketone, nitro, cyano, and amide functions. This excellent chemoselectivity gives zinc- and magnesium-organometallic reagents a central position in modern organic synthesis. Efficient and general preparations of these organometallic reagents, as well as their most practical and useful reactions, are presented in this Perspective. As starting materials, a broad range of organic halides (iodides, bromides, and also to some extent chlorides) can be used for the direct insertion of magnesium or zinc powder; the presence of LiCl very efficiently promotes such insertions. Alternatively, aromatic or heterocyclic bromides also undergo a smooth bromine-magnesium exchange when treated with i-PrMgCl·LiCl. Alternative precursors of zinc and magnesium reagents are polyfunctionalized aryl and heteroaryl molecules, which undergo directed metalations with sterically hindered TMP bases (TMP = 2,2,6,6-tetramethylpiperide) of magnesium and zinc. This powerful C-H functionalization method gives access to polyfunctional heterocyclic zinc and magnesium reagents, which undergo efficient reactions with numerous electrophiles. The compatibility of the strong TMP-bases with BF3·OEt2 (formation of frustrated Lewis pairs) dramatically increases the scope of these metalations, giving for example, a practical access to magnesiated pyridines and pyrazines, which can be used as convenient building blocks for the preparation of biologically active molecules.

[The role of nurses in pharmaceutical care in Germany: A qualitative analysis]. / Die Rolle der Pflegenden in der pharmazeutischen Versorgung in Deutschland ­ Eine qualitative Analyse.

BACKGROUND: In 13 European countries, laws have been passed that allow nurses to prescribe medicines, but mostly within a limited framework and with a doctor involved. Germany is not among these countries. Only the prescription of medical aids has already been included into the development of extended nursing competencies. We investigated the views of the health care professions involved (doctors, pharmacists and nurses) regarding the role of nurses in pharmaceutical care. METHOD: We conducted 22 semi-structured interviews with 23 members of the three professional groups involved in the European research project DeMoPhaC. These data collected in Germany were analysed using qualitative content analysis. Five main categories were developed. RESULTS: Pharmaceutical care by nurses can be described within the following main categories: 1. Knowledge and competences, 2. Patient care, 3. Communication, 4. Multi-professional team and 5. System. The communication between the professional groups involved and with patients and caregivers is of particular importance. Interaction in the multi-professional team is just as crucial. Pharmaceutical care takes place within the health system which sets the framework and often boundaries as well. The current and ideally conceived roles of nurses are seen differently in the respondents' respective contexts. Between the professional groups there is both agreement and dissent on the topics addressed. However, the development of nursing roles requires collaborative and transparent processes in teams and organisations. Particularly in the hospital setting, the participants saw a great need for change in order to achieve cooperation at eye level. DISCUSSION: The results show that nurses play their role in the complex field of pharmaceutical care under very heterogeneous circumstances. The empowerment of nurses, which was called for by some participants, cannot be achieved from within the professional group alone. Cooperation from all the players involved is needed. The development of nursing roles in the medication process with simultaneous expansion of qualifications and competences can contribute to making the nursing role more attractive. Clear role models promote the transparency of processes for all involved. If all players know what they can expect of nurses, tasks can be redistributed in the multiprofessional team. CONCLUSION: The above-mentioned diversity of perspectives can be a resource for development and individual solutions. However, it can also be interpreted negatively as a sign of uncertainty and less standardised ways of working. In view of the data evaluated here, the prescription of medicines by non-medical professionals remains a distant goal for developments in the German health care system. First of all, structures and processes are required that permanently guarantee safe pharmaceutical care with equal participation of all relevant stakeholders.

InCl3-catalyzed synthesis of 1,2-dimetallic compounds by direct insertion of aluminum or zinc powder.

In-sertion of metal: Catalytic amounts of InCl(3) allow the insertion of aluminum and zinc into aromatic 1,2-dibromides or 1,2-bromotriflates. These 1,2-dimetallic species can undergo Cu or Pd-catalyzed acylations, allylations, or cross-couplings.

Integration and Validation of a Natural Language Processing Machine Learning Suicide Risk Prediction Model Based on Open-Ended Interview Language in the Emergency Department.

BACKGROUND: Emergency departments (ED) are an important intercept point for identifying suicide risk and connecting patients to care, however, more innovative, person-centered screening tools are needed. Natural language processing (NLP) -based machine learning (ML) techniques have shown promise to assess suicide risk, although whether NLP models perform well in differing geographic regions, at different time periods, or after large-scale events such as the COVID-19 pandemic is unknown. OBJECTIVE: To evaluate the performance of an NLP/ML suicide risk prediction model on newly collected language from the Southeastern United States using models previously tested on language collected in the Midwestern US. METHOD: 37 Suicidal and 33 non-suicidal patients from two EDs were interviewed to test a previously developed suicide risk prediction NLP/ML model. Model performance was evaluated with the area under the receiver operating characteristic curve (AUC) and Brier scores. RESULTS: NLP/ML models performed with an AUC of 0.81 (95% CI: 0.71-0.91) and Brier score of 0.23. CONCLUSION: The language-based suicide risk model performed with good discrimination when identifying the language of suicidal patients from a different part of the US and at a later time period than when the model was originally developed and trained.

Perspectives of nurses' role in interprofessional pharmaceutical care across 14 European countries: A qualitative study in pharmacists, physicians and nurses.

OBJECTIVES: To understand healthcare professionals' experiences and perceptions of nurses' potential or ideal roles in pharmaceutical care (PC). DESIGN: Qualitative study conducted through semi-structured in-depth interviews. SETTING: Between December 2018 and October 2019, interviews were conducted with healthcare professionals of 14 European countries in four healthcare settings: hospitals, community care, mental health and long-term residential care. PARTICIPANTS: In each country, pharmacists, physicians and nurses in each of the four settings were interviewed. Participants were selected on the basis that they were key informants with broad knowledge and experience of PC. DATA COLLECTION AND ANALYSIS: All interviews were conducted face to face. Each country conducted an initial thematic analysis. Consensus was reached through a face-to-face discussion of all 14 national leads. RESULTS: 340 interviews were completed. Several tasks were described within four potential nursing responsibilities, that came up as the analysis themes, being: 1) monitoring therapeutic/adverse effects of medicines, 2) monitoring medicines adherence, 3) decision making on medicines, including prescribing 4) providing patient education/information. Nurses' autonomy varied across Europe, from none to limited to a few tasks and emergencies to a broad range of tasks and responsibilities. Intended level of autonomy depended on medicine types and level of education. Some changes are needed before nursing roles can be optimised and implemented in practice. Lack of time, shortage of nurses, absence of legal frameworks and limited education and knowledge are main threats to European nurses actualising their ideal role in PC. CONCLUSIONS: European nurses have an active role in PC. Respondents reported positive impacts on care quality and patient outcomes when nurses assumed PC responsibilities. Healthcare professionals expect nurses to report observations and assessments. This key patient information should be shared and addressed by the interprofessional team. The study evidences the need of a unique and consensus-based PC framework across Europe.

TMP-magnesium and TMP-zinc bases for the regioselective metalation of the cinnoline scaffold.

A regioselective functionalization of cinnolines in positions 3 and 8 using metalations has been developed. This involves either the use of a frustrated Lewis pair consisting of BF3·Et2O and TMP2Mg·2LiCl or the in situ generated base TMP2Zn·2MgCl2·2LiCl. Successive metalations allow the preparation of 3,8-disubstituted cinnolines. Various functionalizations by acylation, allylation, and cross-coupling reactions with aryl halides or alkenyl iodides were carried out successfully.

Generation of functionalized aryl and heteroaryl aluminum reagents by halogen-lithium exchange.

Various functionalized aryl and heteroaryl aluminum reagents were obtained by performing I-Li or Br-Li exchange reactions with the corresponding unsaturated organic halides in the presence of i-Bu2AlCl. By means of an appropriate catalyst, the resulting new aluminum species were directly acylated, allylated or arylated. 1,4-Michael additions to enones have also been achieved.
