Abstract:
The purpose of the study was to investigate behavioral and psychological symptoms (BPSD) prevalence, severity, and distress experienced by caregivers of people living with dementia (PLWD). A cross-sectional, population-based study was conducted in a rural area in southwestern Uganda. A Neuropsychiatric Inventory Questionnaire (NPI-Q) was used to determine the presence of BPSD as perceived by caregivers of PLWD. We carried out both descriptive and inferential data analysis. A total of 175 caregivers of PLWD were enrolled in this study. Among PLWD, 99% had presented BPSD in the past month. Hallucinations (75%) and dysphoria/depression (81%) were the two BPSD that occurred most frequently. Most participants (70%) stated that PLWD experienced hallucinations of significant severity. Aberrant motor activity was reported by 60% of the participants as the type of BPSD that caused severe distress. There was a high positive correlation (0.82) between the total severity score and total distress scores. Interventions aimed at addressing dysphoria and hallucinations may be essential for the reduction of caregiver distress. These findings point to the need for promoting early screening for BPSDs and the provision of support to caregivers.

Abstract:
This study was to evaluate the utilization of long-term care service resources by caregivers of patients with dementia (PWD) and to determine affecting factors. In this cross-sectional study, a total of 100 dyads were enrolled and caregivers responded to the questionnaires. We found 40% of caregivers not using any care resources. Between those caregivers using and not-using care resources, we found differences (p < 0.05) in their health status and living conditions; the difference (p < 0.05) was also found in patients’ behavior and psychological symptoms of dementia (BPSD). The frequency of BPSD (OR = 1.045, p = 0.016, 95% CI = 1.001–1.083) and the living conditions (OR = 3.519, p = 0.007, 95% CI = 1.414–8.759) were related to their use of care resources. Particular BPSDs, such as anxiety or restlessness, throwaway food, aggressive behavior, tearing of clothes, and sexual harassment of patients were related to the caregivers’ use of care resources (p < 0.01). Health professionals have to evaluate the patients’ BPSD and identify the caregivers’ essential needs. Individualized medical care and BPSD-related care resources should be provided for patients and caregivers for taking off their care burden and improving patient care.

Abstract:
Bisphenols belong to the endocrine disruptors, affecting reproduction even in extremely low doses. Bisphenol S (BPS) has become widely used as a substitute for the earlier-used bisphenol A; however, its harmlessness is questionable. The aim of this study was to evaluate the effect of BPS on folliculogenesis and oocyte quality afterin vivoexposure to low doses of BPS. Four-week-old ICR females (n = 16 in each experimental group) were exposed to vehicle control (VC), BPS1 (0.001 ng BPS.g/bw/day), BPS2 (0.1 ng.g/bw/day), BPS3 (10 ng.g/bw/day) and BPS4 (100 ng.g/bw/day) for 4 weeks. Ovaries were subjected to stereology and nano liquid chromatography-mass spectrometry (LC/MS). Simultaneously, metaphase II oocytes were obtained after pregnant mare serum gonadotrophin and human chorionic gonadotrophin administration, followed by immunostaining. In particular, mating and two-cell embryo flushing were performed. We observed that BPS decreases the amount of ovarian follicles and BPS2 (0.1 ng.g/bw/day) affects the volume of antral follicles. Accordingly, ovarian proteome is affected after BPS2 treatment. While BPS2 dosing results mainly in cytoskeletal damage in matured oocytes, the effects of BPS3 and BPS4 seem to be due instead to epigenetic alterations in oocytes. Arguably, these changes lead to observed affection ofin vivofertilization rate after BPS3 and BPS4 treatment. BPS significantly affects female reproduction astoundingly in extremely low doses. These findings underline the necessity to assess the risk of ongoing BPS exposure for public health.

Abstract:
Abstract Background During Covid-19 pandemic, the Italian government adopted restrictive limitations and declared a national lockdown on March 9, which lasted until May 4 and produced dramatic consequences on people’s lives. The aim of our study was to assess the impact of prolonged lockdown on behavioral and psychological symptoms of dementia (BPSD). Methods Between April 30 and June 8, 2020, we interviewed with a telephone-based questionnaire the caregivers of the community-dwelling patients with dementia who had their follow-up visit scheduled from March 9 to May 15 and canceled due to lockdown. Among the information collected, patients’ BPSDs were assessed by the Neuropsychiatric Inventory (NPI). Non-parametric tests to compare differences between NPI scores over time and logistic regression models to explore the impact of different factors on BPSD worsening were performed. Results A total of 109 visits were canceled and 94/109 caregivers completed the interview. Apathy, irritability, agitation and aggression, and depression were the most common neuropsychiatric symptoms experienced by patients both at baseline and during Covid-19 pandemic. Changes in total NPI and caregiver distress scores between baseline and during lockdown, although statistically significant, were overall modest. The logistic regression model failed to determine predictors of BPSD worsening during lockdown. Conclusion This is one of the first studies to investigate the presence of BPSD during SARS-CoV-2 outbreak and related nationwide lockdown, showing only slight, likely not clinically relevant, differences in BPSD burden, concerning mostly agitation and aggression, anxiety, apathy and indifference, and irritability.

Abstract:
Abstract Most persons living with dementia (PLwD) experience behavioral and psychological symptoms of distress in dementia (BPSDs). Despite increased utilization of bright light to improve BPSDs, the evidence of effectiveness and dosage using ambient light has not been comprehensively examined. This review synthesized research evidence on the effect of ambient light on BPSD in PLwD. A literature search conducted in Scopus, PubMed, CINAHL, and Web of Science included keywords: dementia, bright light, ambient light, indirect light, behavior symptoms, agitation, wandering, depression, aggression, and apathy. Original studies that examined the effect of ambient light on BPSDs were included. Six studies were identified. Sample size ranged from 6 to 189. Lighting delivery methods included a lighting table and ceiling-mounted fixtures in public areas and/or participant’s bedroom. Lighting intensity ranged from 1,000-3,000 lux, color temperature ranged from bluish white to warm white, and exposure duration ranged from 4 to 24 hours a day. PLwD with higher light exposure showed more pleasure and alertness. Ambient bright lighting showed mixed results in reducing agitation with one study reporting increased agitation. Three out of four studies showed positive effects upon depressive symptoms. Ambient bright light positively impacted pleasure and alertness. Mixed results on agitation and depressive symptoms may be explained by differences in illuminance, color, duration, and targeted lighting positions. Further studies are needed to confirm the positive effects of ambient light on BPSD. Accurate lighting exposure measurements related to spectral compositions and dosage for individual PLwD would help explain the underlying relationships between lighting and BPSD.

Abstract:
The relationship between plasma homocysteine and behavioral and psychological symptoms of dementia (BPSD) has not been specifically investigated in previous research. In this study, we compared plasma homocysteine (Hcy) among 40 Alzheimer’s disease (AD) patients with BPSD, 37 AD patients without BPSD, and 39 healthy controls. Our results evidenced that the plasma homocysteine levels in AD patients with BPSD and without BPSD were higher than healthy controls and that the plasma homocysteine concentration in AD patients with BPSD was the highest among the three groups. Significant correlation between plasma homocysteine concentration and cognitive decline and duration of dementia was observed, but there was no correlation between BPSD and cognitive dysfunction or duration of dementia. In conclusion, this study showed for the first time that BPSD were associated with plasma homocysteine concentration in Alzheimer's dementia, and the results supported that hyperhomocysteine may take part in the pathogenesis of BPSD.

Abstract:
Abstract Behavioral and psychological symptoms of dementia (BPSD) are taxing for both the person with dementia (PWD) and their family caregivers. Yet, little is known about how BPSD fluctuates throughout the day (i.e., morning, daytime, evening, and night; e.g., sundowning) and how caregivers perceive BPSD at different times of the day. Using 8-day daily diary data from 173 family caregivers whose relatives were using Adult Day Services (ADS), this study investigated temporal patterns of BPSD and caregivers’ stress responses to BPSD throughout the day. Overall, the number of BPSD was highest in the evening, and caregivers’ stress reactivity to BPSD increased throughout the phases of the day (i.e., most stressful at night). However, caregivers showed lower reactivity to BPSD in the mornings and at night on days when the PWD used ADS. Our findings about fluctuations of (caregiver reactions to) BPSD throughout the day suggest target windows for just-in-time adaptive intervention.

Abstract:
Background: The occurrence of Behavioral and Psychological Symptoms of Dementia (BPSD) in Alzheimer’s Disease (AD) patients hampers the clinical management and exacerbates the burden for caregivers. The definition of the clinical distribution of BPSD symptoms, and the extent to which symptoms are genetically determined, are still open to debate. Moreover, genetic factors that underline BPSD symptoms still need to be identified. Purpose. To characterize our Italian AD cohort according to specific BPSD symptoms as well as to endophenotypes. To evaluate the associations between the considered BPSD traits and COMT, MTHFR, and APOE genetic variants. Methods. AD patients (n = 362) underwent neuropsychological examination and genotyping. BPSD were assessed with the Neuropsychiatric Inventory scale. Results. APOE and MTHFR variants were significantly associated with specific single BPSD symptoms. Furthermore, “Psychosis” and “Hyperactivity” resulted in the most severe endophenotypes, with APOE and MTHFR implicated as both single risk factors and “genexgene” interactions. Conclusions. We strongly suggest the combined use of both BPSD single symptoms/endophenotypes and the “genexgene” interactions as valid strategies for expanding the knowledge about the BPSD aetiopathogenetic mechanisms.

Abstract:
Dementia encompasses both cognitive and noncognitive domains. Noncognitive symptoms include disorders of behavior, personality, mood, thought content, and perception and impaired functional ability. Behavioral, personality, mood, and thought content disorders have been labeled behavioral and psychological symptoms of dementia (BPSD) following a previous International Psychogeriatric Association consensus conference. Traditionally, BPSD have been poorly studied for several reasons, including the lack of importance attached to cognition in the diagnosis of dementia, the assumption that BPSD are secondary to cognitive and personality changes, the difficulty of accurately defining BPSD, and the paucity of standardized instruments to measure BPSD. Historically, all BPSD tended to be studied together under one broad umbrella and thus older data on individual BPSD are limited. Differing definitions, patient populations, study designs, data collection methods, measurement instruments, and methodologic issues influence the prevalence of the various BPSD reported in different studies, making comparisons between studies difficult.

Abstract:
Abstract The epidemiology of Behavioral and Psychological Symptoms of Dementia (BPSD) in hospitalized older adults with Alzheimer’s Disease (AD) and AD-related dementias (ADRD) has not been well-characterized. The purpose of this abstract is to examine the prevalence, patient-level factors and hospital outcomes associated with BPSD in hospitalized older adults with AD/ADRD. Data was extracted from the electronic health record (EHR) of older adults (aged 65+ years) with AD/ADRD, admitted to one of 7 hospitals in the greater New York metropolitan area during 2019. Three independent coders reviewed the EHR and recorded the presence or absence of the 11 domains of the Neuropsychiatric Inventory (NPI), a validated measure of BPSD. Of N = 1,865 hospitalized older adults with AD/ADRD, 1,564 had BPSD (prevalence = 83.9%). The most commonly reported BPSD were agitation (72.3%) and anxiety (17.7%). Older age (M = 84.6, SD = 7.6 versus M = 82.4, SD = 7.8, p = .000) and antipsychotic medication use prior to hospital admission (91% of the older adults who used home antipsychotics had BPSD, p = 000) was associated with BPSD. With regard to hospital outcomes, BPSD was associated with: increased mortality (of those who died, 90.6% had BPSD, p = .006), and increased likelihood of readmission to the hospital within 30 days of discharge (of those readmitted, 89.3% had BPSD, p = .007). Given its high prevalence and associated poor outcomes, recognizing and managing BPSD in hospitalized patients with AD/ADRD is critical to improving quality of care for this vulnerable population.

Abstract:
Kognitiv sjukdom eller demenssjukdom är ett samlingsbegrepp som innefattar flera olika kroniska sjukdomar. Gemensamt är att de påverkar hjärnan på olika sätt och leder till att personen som drabbas sviktar i olika kognitiva domäner. Nio av tio personer med kognitiv sjukdom drabbas av beteendemässiga och psykiska symtom vid demenssjukdom. Beteendemässiga och psykiska symtom vid demenssjukdom kan leda till stort lidande och kan vara svårt att hantera även för närstående och personal. Icke-farmakologiska åtgärder har högst prioritet i behandlingen av beteendemässiga och psykiska symtom vid demenssjukdom. Musikbaserade terapeutiska interventioner är en av dessa åtgärder som fått ökad uppmärksamhet. Metoden har även stöd i beprövad erfarenhet. För att kunna erbjuda en personcentrerad omvårdnad och använda sig av ett brett utbud av omvårdnadsåtgärder behöver vårdpersonal ha kännedom om dessa metoder och hur de fungerar.  Syftet med studien var att undersöka effekter av musikbaserade terapeutiska interventioner på de beteendemässiga och psykiska symtom som kan uppstå vid kognitiv sjukdom. Metod var litteraturstudie med systematisk struktur. Sökningarna genomfördes i databaserna PubMed och CINAHL. Sammanlagt inkluderades 15 vetenskapliga kvantitativa artiklar som först kvalitetsgranskades för att sedan analyseras med integrerad analys. Resultatet kategoriserades i två huvudkategorier ”Effekt på beteendemässiga symtom” och ”Effekt på psykiska symtom”. Artiklarna visade störst effekt på de psykiska symtomen och då främst på depression och ångest. Resultatet visade även att musikbaserade terapeutiska interventioner kunde minska vanföreställningar, hallucinationer och apati. Viss effekt sågs också på beteendemässiga symtom som aggression och agitation. Resultatet visade att effekten i de allra flesta fall avtog efter tre till fyra veckor.  Slutsats från studien var att musikbaserade terapeutiska interventioner kan ha effekt på beteendemässiga och psykiska symtom vid demenssjukdom. Effekt sågs framförallt på de psykiska symtomen vilket överensstämmer med tidigare forskning. I syfte att på bästa sätt undvika potentiellt farliga läkemedel för personer med beteendemässiga och psykiska symtom vid demenssjukdom är icke-farmakologiska metoder prioriterat enligt de svenska nationella riktlinjerna vid demenssjukdom. Genom att praktisera en personcentrerad omvårdnad och använda sig av musik i terapeutiskt syfte kan vårdpersonal påverka negativa symtom och på så sätt höja livskvaliteten för personer som upplever beteendemässiga och psykiska symtom vid demenssjukdom.
Neurocognitive disorder or dementia are collective terms for several chronic diseases. What they have in common is that they affect the brain in different ways and the person being affected fails in different cognitive domains. Nine out of ten persons with dementia suffer from behavioural and psychological symptoms of dementia. Behavioural and psychologicalsymptoms of dementia can lead to great suffering and can be difficult to manage for relativesand staff. Non-pharmacological interventions have the highest priority in the treatment of behavioural and psychological symptoms of dementia. Music-based therapeutic interventions are one of these interventions that have received increased attention. The method is also supported by proven experience. To be able to offer person-centred nursing and make use of a wide range of nursing measures, care staff need to be aware of these methods and how they work. The aim of this study was to investigate the effects of music-based therapeutic interventions on the behavioural and psychological symptoms that can occur in cognitive disorder. The method was a literature review with systematic structure. The searches were performed in the databases PubMed and CINAHL. A total of 15 scientific quantitative articles were included, which were firs quality reviewed and then analysed with integrated analysis.  The results were categorized into two main categories. “Effect on behavioural symptoms” and “Effect on psychological symptoms”. The articles showed greatest effect on psychological symptoms and then mainly on depression and anxiety. The results also showed that music-based therapeutic interventions could reduce delusions, hallucinations and apathy. Some effect was also seen on behavioural symptoms such as aggression and agitation. The results showed that in most cases the effect diminished after three to four weeks. The study concluded that music-based therapeutic interventions may have an effect on behavioural and psychological symptoms of dementia. The effect was seen mainly on the psychological symptoms, which is consistent with previous research. In order to best avoid potentially dangerous drugs for people with behavioural and psychological symptoms of dementia, non-pharmacological methods are prioritized according to the Swedish national guidelines for care of dementia. By practicing person-centred nursing and using music for therapeutic purposes, healthcare professionals can influence negative symptoms and thus increase the quality of life for people who experience behavioural and psychological symptoms of dementia.

Abstract:
Allt fler personer drabbas av demenssjukdom och en stor del av dessa drabbas någon gång av ett eller flera beteendemässiga och psykiska symtom vid demens (BPSD). BPSD skapar stort lidande för den drabbade men kan även vara svårt att hantera för människorna omkring dem, närstående och vårdpersonal, och är en stor anledning till att personen flyttar till särskilt boende. Syftet med studien var att beskriva vårdpersonalens upplevelser av att vårda personer med beteendemässiga och psykiska symtom vid demens. Studien hade en beskrivande design med kvalitativ ansats. Data samlades in via sex individuella semi-strukturerade intervjuer. Genom bekvämlighetsurval rekryterades undersköterskor på ett demensboende i Sverige. Data analyserades med kvalitativ innehållsanalys. Ett övergripande tema framträdde i resultatet, ”Svårigheter att finna balans mellan behov och resurser”. Informanterna upplevde arbetet med personer med BPSD som en stor utmaning men att det var mycket givande. Känslan av att inte räcka till, att sakna kunskap eller förmåga att hantera vissa situationer eller symtom samt bristen på resurser upplevdes som påfrestande av informanterna. Aggressivitet, oro och ångest hos personer med BPSD var de symtom som upplevdes som svårast att hantera. Resultatet visar även att informanterna upplevde arbetet med personer med BPSD som spännande, intressant och roligt och att de kände tillfredsställelse i att finnas där för personen med BPSD och att kunna bidra till deras välmående. Studiens slutsats visar att informanterna upplevde stora utmaningar i sitt arbete med att skapa välbefinnande för personer med BPSD. Stöd och utbildning skulle kunna öka arbetstillfredsställelsen för vårdpersonalen men även livskvaliteten för personer med BPSD.
More and more people suffer from dementia and a large part of these is affected by some point of one or several behavioral and psychological symptoms of dementia (BPSD). BPSD creates great suffering for the affected but can also be difficult for the people around them to manage, relatives and health professionals, and is a big reason that a person moves in to a nursing facility. The aim of this study was to describe health professional’s experience of caring for persons with behavioral and psychological symptoms in dementia, BPSD. The study had a descriptive design with qualitative approach. Data were collected through six individual semi-structured interviews. By convenience sampling, nursing assistant working at a nursing facility for people with dementia in Sweden were recruited. Data were analyzed by qualitative content analysis. A theme emerged, “Difficulties to find a balance between need and resource”. The informants experienced their work in caring for people with BPSD as a great challenge but also as very awarding. The feeling of being inadequate, lacking knowledge or ability to handle certain situations or symptoms and lack of resources perceived as stressful by the informants. Aggressiveness and anxiety in individuals with BPSD were experienced as the most difficult to handle. The results also showed that the informants experienced working with persons with BPSD as exiting, interesting and fun and that they felt satisfaction in being there for the person with BPSD and to be able to contribute to their well-being. The conclusion in this study shows that informants experienced great challenges in their work to create wellbeing for people with BPSD. Support and education could increase the job satisfaction for the health personnel but also increase the quality of life for people with BPSD.

Abstract:
Bakgrund:I takt med att antalet äldre i Sverige ökar, ökar också antalet insjuknade i demens. Nio av tio personer som drabbas av demenssjukdom kommer att uppvisa beteendemässiga eller psykiska symtom någon gång under sjukdomsförloppet. Dessa symtom har visat minska livskvalitén och utgör den vanligaste orsaken till att personer med demenssjukdom flyttar till ett särskilt boende då belastningen på anhöriga och omgivningen blir alltför stor. Syfte:Att beskriva omvårdnadsåtgärder i arbetet med patienter som uppvisarbeteendemässiga och psykiska symtom vid demenssjukdom. Metod:Studien är en litteraturstudie baserad på niovetenskapliga artiklar med både kvalitativ och kvantitativ ansats som sökts fram via databasen Cinahl. Artiklarna har analyserats med fokus på att finna likheter och skillnader i resultatet av de valda studierna.. Analysarbetet resulterade i fyra huvudkategorier som visade sig vara viktiga faktorer som påverkar omvårdnadsåtgärder för denna patientgrupp: utbildning, personcentrerad omvårdnad, musik, dans och beröring. Resultatet kommer att diskuteras med hjälp av Katie Erikssons teori kring lidandet som också utgör studiens teoretiska referensram. Resultat:Utbildning och användandet av en mer personcentrerad omvårdnad är två sätt att skapa goda förutsättningar för att kunna lindra, förebygga och behandla beteendemässiga och psykiska symtom vid demenssjukdom. Vidare behandlar resultatet dans, musik och beröring som tre mer eller mindre effektiva omvårdnadsåtgärder som omvårdnadspersonal kan använda i sitt arbete med patienter som uppvisar beteendemässiga och psykiska symtom i sin demenssjukdom. Diskussion:Beteendemässiga och psykiska symtom vid demenssjukdom utgör både ett lidande för patienten och vårdpersonalen. Denna aspekt lyfts i resultatdiskussionen och relateras till Erikssons sätt att se på lidande. Diskussion sker kring de omvårdnadsåtgärder som framkom i resultatet med utgångspunkt i lidande.

Abstract:
Bakgrund: I Sverige finns idag ca 158 000 individer som lever med en demenssjukdom. De är i behov av en anpassad vårdmiljö och personlig omvårdnad relaterat till de svårigheter som sjukdomen kan skapa. BPSD (beteendemässiga och psykiska symtom vid demens) drabbar mer än 90% av individer med demens. BPSD ökar risken för personer med demens att bli utsatta för fysiska övergrepp, social isolering, onödig användning av antipsykotiska läkemedel samt försämring av sociala och fysiska funktioner. Syfte: Att belysa effekter av sjuksköterskebaserade interventioner vid beteendemässiga och psykiska symtom hos individer med demens. Metod: Arbetet var en litteraturstudie. Fyra artiklar inkluderades från databaserna Cinahl och PubMed. Resterande fyra artiklar hämtades genom manuella sökningar. Artiklarna kvalitetsgranskades och analyserades. Resultat: I vårt resultat framkom tydliga effekter av sjuksköterskebaserade interventioner vid BPSD: Det psykiska och fysiska välbefinnandet ökade. Sinnesstämningen förändrades och de emotionella störningarna minskade. Relationer stärktes både till sig själv och andra. Förändrade beteenden kunde ses i form av att ilska och andra beteendemässiga symtom på BPSD minskade. Slutsats: Resultatet visade att sjuksköterskebaserade interventioner och personcentrerad vård kunde leda till många positiva effekter för individer med demens. En aspekt som anses viktig att forska vidare kring är om sjuksköterskans interventioner till viss del skulle kunna ersätta antipsykotiska läkemedel för individer med beteendemässiga och psykologiska symtom vid demens.

Abstract:
Abstract In this study eight caregivers, all with long experience from working in nursing homes for people with dementia, were interviewed.  The aim of the study was to describe the caregiver’s experiences in caring for people with dementia and Behavioral and Psychological Symptoms of Dementia disorder. Data were processed by qualitative, inductive, content analysis. The results were presented in four categories: To connect, Two days are never the same, Being calm and giving time and All are needed. The result showed that caregivers met a variety of difficult and varied tasks in nursing. The caregivers responded to people with dementia disorder by adjusted the meeting based on current conditions. They also spoke calmly using few words and let contact with the person with dementia disorder take time. They used both verbal and nonverbal communication to create contact, sometimes they even used humor or music to connect. However, a good treatment presupposes supportive context, both at the group and organizational level. The caregivers mentioned the importance of a functional team where continuous needs-based planning and clear objectives were essential elements in the care of people with dementia disorder. The nurse, specialist in elder care, has a central role in the care for persons with dementia. With her expertise nursing is able to develop and ensure the care as well as combine the theoretical knowledge together with work experience. Keywords: Dementia, Elder, Experiences, Nursing home
ABSTRAKT I föreliggande studie har åtta vårdpersonal med lång erfarenhet av arbete på vård och omsorgsboende för personer med demenssjukdom personer intervjuats. Syftet med denna studie var att beskriva vårdpersonals upplevelse av att vårda personer med demenssjukdom och BPSD. Materialet analyserades med kvalitativ innehållsanalys och induktiv ansats. Analysen resulterade i fyra kategorier: Att skapa kontakt, Ingen dag är den andra lik, Vara lugn och ta sig tid samt Alla behövs. Resultatet visade att vårdpersonal i vård och omsorgsboende ställdes inför en mängd svåra och varierande uppgifter i omvårdnaden. Vårdpersonalen bemötte personerna med demenssjukdom genom att anpassa mötet utifrån rådande förutsättningar. Vårdpersonalen pratade lugnt, använde få ord och lät kontakten ta tid. Både verbal och icke verbal kommunikation användes för att få kontakt och i vissa fall humor och musik. Ett gott bemötande förutsatte emellertid ett stödjande sammanhang både på grupp- och organisationsnivå.  Vårdpersonalen beskrev betydelsen av ett fungerande team där kontinuerlig behovsbaserad planering och en tydlig målsättning var viktiga delar i vården av personer med demenssjukdom. Specialistsjuksköterskan inom vård av äldre har en central roll i att leda och samordna vårdarbetet i teamet med den demenssjuke personens behov som utgångspunkt. Med sina expertkunskaper kan sjuksköterskan utveckla omvårdnadsarbetet och säkerställa att den teoretiska kunskapen omsätts och kombineras med erfarenhetsbaserad kunskap.   Nyckelord: Demens, Äldre, Upplevelser, Vård och omsorgsboende

Abstract:
Syfte: Syftet med studien var att belysa olika omvårdnadsåtgärder som bidrar till att minska beteendemässiga och psykiska symtom vid demens (BPSD). Metod: Examensarbetet har utförts som en litteraturstudie med 15 vetenskapliga artiklar varav fem kvantitativa och tio kvalitativa. Datainsamling har genomförts i de vårdvetenskapliga databaserna CINAHL och PubMed. Resultat: De olika omvårdnadsåtgärderna som bidrog till att minska BPSD var att anpassa vårdmiljön genom färgsättning och möjlighet till enkelrum samt egen toalett, även att använda sig av personcentrerad och behovsanpassad vård för att beakta hela människan och dess behov, att stimulera hörsel, lukt och känsel med hjälp av taktil och fotmassage, aromaterapi, akupressur och musik. Samt att använda sig av montessori baserade aktiviteter som innebar att personer fick ägna sig åt intressen som de haft innan sjukdomen uppkom och teoretiskt baserade aktiviteter såsom att läsa tidning och lösa korsord. Dessa omvårdnadsåtgärder bidrog till att minska symtom vid BPSD såsom agitation, aggression samt verbal aggression. Konklusion: Genom att anpassa vårdmiljön med hjälp av design och anpassning, att använda sig av personcentrerad och behovsanpassad vård, att stimulera hörsel, lukt och känsel som taktil och fotmassage, aromaterapi, akupressur och musik. Samt att använda sig av montessori baserade aktiviteter och teoretiskt baserade aktiviteter minskas BPSD samtidigt som möjligheten till en god omvårdnad förbättras och livskvaliteten hos personer med demenssjukdom kan öka.

Abstract:
Bakgrund Demenssjukdomar, som blir allt vanligare, kan medföra beteendemässiga och psykiska symtomvid demens (BPSD). Dessa symtom förekommer någon gång hos ungefär 90 % av alla personermed demenssjukdom. BPSD kan innebära ett stort lidande för såväl den demenssjuke som fördennes anhöriga samt en yrkesmässig utmaning för vårdpersonalen. Syfte Syftet med denna litteraturstudie är att belysa olika utbildningar för personal som arbetar isärskilda boenden och vårdar brukare med oro/agitation kopplat till BPSD samt att beskriva deneffekt utbildningarna givit vad gäller oro/agitation som är kopplat till BPSD. Metod En litteraturstudie har genomförts med sökning i databaserna ”PubMed” och ”CINAHL”. Åttakvantitativa interventionsstudier som motsvarade syftet har analyserats och granskats.ResultatVi har i denna studie kommit fram till att utbildningar som syftat till individanpassade strategierför brukarna har givit positiv effekt vad gäller oro/agitation. Slutsats Studierna vi tittat på uppfattades vid en första anblick som tämligen olika. De har varierat mellanlängre och kortare utbildningar samt har haft olika innehåll, men det som vi har kunnat se somden gemensamma nämnaren för alla dessa utbildningar är att fokus ligger på individen och inte påsjälva sjukdomen. I denna studie har vi kunnat se ett positivt samband mellan personalutbildningsom syftar till individanpassade insatser och en minskad oro/agitation hos brukare med BPSD.
Background Dementia can cause behavioural and psychological symptoms of dementia (BPSD). Thesesymptoms may occur sometimes in approximately 90% of all people with dementia. BPSD caninvolve a great deal of suffering for both the person suffering from dementia as for his or herfamily and constitutes a professional challenge for the staff. Aim The aim of this study is to illustrate some of the educational interventions that exists for the staffcaring for persons suffering from anxiety/agitation caused by BPSD, the effect those interventionshas had on anxiety/agitation related to BPSD. Method A literature search has been made in the databases ”PubMed” and ”CINAHL”. A total of eightquantitative articles were selected, reviewed and analysed.ResultsThe result of this study indicated that staff education that aims to give individualized interventionsfor the residents seem to have a positive effect on anxiety/agitation on persons suffering fromdementia. Conclusions The educational interventions reviewed in this study was at a first glance quite different from eachother but the thing that was common in all the studies was that they aimed to give individualizedinterventions for the residents. In this study, we could see a positive connection between staffeducation aiming to give individualized interventions based on the resident’s preferences and adecreased level of anxiety/agitation in residents suffering from BPSD.

Abstract:

Bakgrund: I Sverige insjuknar varje år cirka 24 000 personer i demenssjukdom. Då medellivslängden stiger, ökar antalet insjuknande för varje år. Att insjukna i demenssjukdom innebär både psykiska och fysiska funktionsnedsättningar i form av Beteendemässiga och Psykiska Symtom vid Demenssjukdom (BPSD) som kan leda till problem i det dagliga livet. Studier har visat att musikterapi kan vara ett av många alternativ till icke farmakologisk behandlig vid BPSD hos personer med demenssjukdom.Syfte: Syftet med litteraturstudien var att beskriva hur musik inverkar på personer med demenssjukdom.Metod: En allmän litteraturöversikt gjordes, där litteratur söktes utifrån syftet via databassökningar. Tio vetenskapliga artiklarn valdes ut, granskades och analyserades.Resultat: Resultatet visade på att musik kunde ge viss inverkan på personer med demenssjukdom. Musiken inverkade både positivt och negativt på Beteendemässiga och Psykiska Symtom vid Demenssjukdom. Individuellt utvald musik visade större inverkan än slumpvist utvald musik. Musik som personer med demenssjukdom tyckte om, skapade en god sinnesstämning vilket ledde till en ökad social interaktion.Slutsats: Även om musik inte gav en inverkan hos alla personer med demenssjukdom, kan musik vara en alternativ resurs till de personer med demenssjukdom som musik inverkade på. Musik inom omvårdnaden kan reducera BPSD och öka sinnesstämningen och den sociala interaktionen, vilket kan stärka KASAM hos personer med demenssjukdom.


Background: Each year around 24 000 people are diagnosed with dementia disease in Sweden. Further with the rise in life expectancy, the number of persons affected increases. Dementia results in both psychiatric and physical disabilities in the shape of behavioral and psychiatric symptoms (BPSD) that can lead to problems in daily life. Studies show that music therapy can be one of many options to non-pharmacological treatment for BPSD in people with dementia disease.Purpose: The purpose of this study is to describe how music can influence people with dementia. Method: A literature review was made of ten scientific articles, sought through databases . Ten selected articles were carefully analyzed.Results: The results show that music produced some effects on dementia patients. The music influenced both positively and negatively the behavioral and psychological symptoms of dementia. Music individually selected by the patients themselves had a greater effect than the music selected at random. The positive effects of music created a state of mind which led to increased social interaction.Conclusion: Although all patients were not affected by the music, it can be an alternative resource for those that are. Affected the use of music in medical care may reduce the BPSD and raise the state of mind and better social interaction, thus improving SOC in dementia patients.

Abstract:
Background: Older people with dementia may experience behavioral and psychological symptoms during the course of the illness. Non-pharmacological therapies are considered strategies to manage these symptoms. Objective: to investigate whether physical exercise reduces BPSD in older people with Mild Cognitive Impairment (MCI) and dementia. Methods: A systematic review was performed in the MEDLINE, SciELO, Web of Science, Scopus and SPORTDiscus databases from 2010 to 2020. Randomized clinical trials involving older people with MCI or dementia that evaluated BPSD as a primary or secondary outcome were included. The studies had an exercise-only group as an intervention compared to the control group. Results: Of the 175 publications identified, only 7 met the eligibility criteria; 4 studies showed positive effects in reducing BPSD, while the others did not differentiate the gains according to the type of protocol. Conclusion: Aerobic and muscle-strengthening exercises of moderate to vigorous intensity may have potential benefit in the management of BPSD, but studies vary in their conclusions. This review identified the need for further intervention studies to investigate the absolute effect of physical exercise and its impact on BPSD as a primary outcome, especially in the early stages of the disease.

Abstract:
A majority of research on ionic polymer transducers has used Nafion™ as the base material. Varying the physical and chemical properties of Nafion is difficult, which limits the understanding and development of ionic transducers. In this study we investigate a novel class of polymers called BPSH (sulfonated poly(arylene ether sulfone)s). The polymers are synthesized by the direct polymerization of sulfonated monomers. This synthetic scheme affords precise control of the amount and the location of ionic groups along the polymar backbone. These polymers differ from Nafion™ in two major ways. First, the concentration of ionic groups on a mass basis is almost double that of standard Nafion™, 1.51 meq/g for BPSH-30 versus 0.91 meq/g for Nafion™ 1100. Also, the backbone of the BPSH copolymers is much stiffer than Nafion, which affords a higher modulus material. Both of these factors, ion content and modulus, are expected to affect the performance of polymer-based actuators. Another ionomer characterized is the PATS (poly(arylene thiother sulfone)s) which is similar to BPSH. For both polymers we are varying the ionic concentration, stiffness, and water content. Those variations are fostering the understanding of operating concepts of ionic transducers, especially the correlation between ionic transducers, especially the correlation between ionic concentration and performance. Experiments on BPSH-35 demonstrate improved performance as compared to Nafion™ They provide larger strain per unit volt, larger force generated, and larger bandwidth. The novel polymers are characterized as sensors and actuators.

SWEBOK is a guideline that provides information about Software Engineering (SE) knowledge, including a list of Best Practices (BPs) for adopting. However, small companies have restrictions such as, limited budget, reduced schedule, and, small staff that can hinder the advantages of these BPs adoption. Thus, this paper investigated the last decade of BPs adoption reported by small companies’ environment. A quasi-systematic mapping was conducted for assessing studies that addressed this issue, and it was possible to observe that the most prominent BPs adopted are “test application” and “software process model adoption”. On the other hand, “limited budget” and “staff size” were found as causes for non-adoption of SWEBOK’s BPs.

BPSK and 8-FSK modulation techniques are used in a variety of wireless communication systems. It has a substantial impact on wireless communication channels. The significance of analyzing and comparing the performance of these two modulation techniques over the AWGN fading channel cannot be overstated. This research can be used to determine the best technique for implementing in an AWGN fading channel. To investigate the performance of BPSK and 8-FSK modulation schemes on an AWGN channel in order to calculate the error rate quantity, and to provide a solution in such cases by providing a simple programmable interface for error rate calculators and switching between different techniques using channel block-sets. The performance analysis is carried out by utilizing the MATLAB Simulink software to synthesize the design. A simulated comparative result is shown using the AWGN channel to analyze the performance of these systems. The results clearly show that the BPSK modulation technique outperforms the 8-FSK modulation technique over the AWGN channel.

Abstract:
For reducing fuel cell stack cost new materials for bipolar plates (BPs) are under development. Quality of this new BPs has to be checked. The four-points probe method is commonly used for measuring of electrical conductivity; however sample’s geometry has a strong impact on the accuracy of this method. For this reason, it is not possible to use the classical assumptions for the interpretation of the electrical conductivity measurements with respect to the case of BPs. In this paper, a finite elements numerical model is developed for the calculation of the influence of the sample’s geometry on the accuracy of four-points probe method. The approach presented here allows obtaining the corrective factor for the four-points method taking into account the real geometry of BPs and evaluating the border effects related with the position of the probe. The obtained results can be used for diagnostic of the quality of BPs.

Abstract:
ABSTRACT: The shale oil reservoir of Lucaogou Formation is characterized by complex lithology changes in vertical direction and lamination. To simulate the lithology variation of shale oil formation, downhole cores with different lithologies were prepared and bonded to layered samples. After that, the influence of interlaminar difference on propagation behavior of hydraulic fractures (HFs) was investigated through laboratory hydraulic fracturing and mechanical characteristics analysis. The result shows that mechanically weak bedding planes (BPs) leads to obvious anisotropy of rock mechanical properties. The rock samples is unstable when loaded along the parallel BPs direction, the tensile strength decline significantly, which is about 20% of the tensile strength measured perpendicular to BPs. The brittleness of rock samples measured parallel to BPs is greater than that measured perpendicular to BPs, by about two times. This results in HFs induced by low-viscosity slickwater are easily arrested by BPs, can not penetrate interlayer. HFs induced by high viscosity gel can penetrate the bonding interface. The difference of tensile strength between layers increases, the decrease degree of fracture width increases 2.5 times. This will impede proppant placement in interlayer. This research results provide a basis for the optimization of hydraulic fracturing of Lucaogou shale oil reservoir. 1. INTRODUCTION The reservoirs of Lucaogou Formation in Jimusar sag, Junggar Basin are saline lacustrine and delta facies (Zou et al., 2020; Nie et al., 2011). The variation of climate and source supply intensity as well as the periodical fluctuation of lake level lead to the longitudinal lithology variation, and BPs development (Li et al., 2020; Zhang et al., 2021; Yang et al., 2018; Zhi et al., 2019 ). The influence of interlayer difference and BPs on reservoir fracture propagation is unclear. The selection of fracturing techniques and engineering parameters lacks theoretical support, and HFs height and vertical fracturing volume are limited (Lei et al., 2021; Jiang et al., 2021;). Understanding the influence of interlayer difference and BP structure on fracture propagation is the key to optimize hydraulic fracturing strategy, which is of great significance to improve the adaptability of fracturing process parameters and realize the overall utilization of multi-layer sweet spot body.

Abstract:
Review question / Objective: This scoping review study aims to identify, summarize, and appraise available literature regarding the role of (BPSD)/neuropsychiatric symptoms in patients’ autonomy with all types of dementia diagnoses. To accomplish this objective, this scoping review will address the following question: What is the role of behavioral and psychological symptoms of dementia in the patient’s autonomy? This review will comprise the terms capacity, functional abilities, and competence in the autonomy concept. Background: Dementia is a neurodegenerative syndrome characterized by the development of multiple cognitive deficits and behavioral changes that interferes with multiple aspects of life, including cognition, daily functioning, and behavioral. With the progress of the disease, the patients lose their capacity, functional abilities, competence, and autonomy (Barbas & Wilde, 2001; Darby & Dickerson, 2017; Irastorza, Corujo, & Bañuelos, 2011; Lee, Jang, & Chang, 2019; Marson, 2013).

Abstract:
This research brief uses nationally representative data from the 2012/17 Beginning Postsecondary Students Longitudinal Study (BPS:12/17) to examine post-college transitions of US undergraduates into the skilled technical workforce (STW), defined here as workers in a collection of occupations that require significant levels of science, technology, engineering, and mathematics (STEM) knowledge but not necessarily a bachelor’s degree for entry. Thus far, empirical research on the STW has been limited by a dearth of data; however, based on newly available data from BPS:12/17, the findings in this report indicate that STW employment provides workers with above-median salaries, more equitable wages, a variety of benefits, and clear career paths. STW jobs attract diverse populations, especially those from underrepresented groups (e.g., Hispanics, individuals from low-income backgrounds, and those whose parents do not have college education). US community colleges and sub-baccalaureate programs play a large role in developing the STW.

Lers, Amnon, and Gan Susheng. Study of the regulatory mechanism involved in dark-induced Postharvest leaf senescence. United States Department of Agriculture, January 2009. http://dx.doi.org/10.32747/2009.7591734.bard.

Abstract:
Postharvest leaf senescence contributes to quality losses in flowers and leafy vegetables. The general goal of this research project was to investigate the regulatory mechanisms involved in dark-induced leaf senescence. The regulatory system involved in senescence induction and control is highly complex and possibly involves a network of senescence promoting pathways responsible for activation of the senescence-associated genes. Pathways involving different internal signals and environmental factors may have distinctive importance in different leaf senescence systems. Darkness is known to have a role in enhancement of postharvest leaf senescence and for getting an insight into its regulatory mechanism/s we have applied molecular genetics and functional genomics approaches. The original objectives were: 1. Identification of dark-induced SAGs in Arabidopsis using enhancer/promoter trap lines and microarray approaches; 2. Molecular and functional characterization of the identified genes by analyzing their expression and examining the phenotypes in related knockout mutant plants; 3. Initial studies of promoter sequences for selected early dark-induced SAGs. Since genomic studies of senescence, with emphasis on dark-induced senescence, were early-on published which included information on potential regulatory genes we decided to use this new information. This is instead of using the uncharacterized enhancer/promoter trap lines as originally planned. We have also focused on specific relevant genes identified in the two laboratories. Based on the available genomic analyses of leaf senescence 10 candidate genes hypothesized to have a regulatory role in dark-induced senescence were subjected to both expression as well as functional analyses. For most of these genes senescence-specific regulation was confirmed, however, functional analyses using knock-out mutants indicated no consequence to senescence progression. The transcription factor WARK75 was found to be specifically expressed during natural and dark-induced leaf senescence. Functional analysis demonstrated that in detached leaves senescence under darkness was significantly delayed while no phenotypic consequences could be observed on growth and development, including no effect on natural leaf senescence,. Thus, WARKY75 is suggested to have a role in dark-induced senescence, but not in natural senescence. Another regulatory gene identified to have a role in senescence is MKK9 encoding for a Mitogen-Activated Protein Kinase Kinase 9 which is upregulated during senescence in harvested leaves as well as in naturally senescing leaves. MKK9 can specifically phosphorylate another kinase, MPK6. Both knockouts of MKK9 and MPK6 displayed a significantly senescence delay in harvested leaves and possibly function as a phosphorelay that regulates senescence. To our knowledge, this is the first report that clearly demonstrates the involvement of a MAP kinase pathway in senescence. This research not only revealed a new signal transduction pathway, but more important provided significant insights into the regulatory mechanisms underlying senescence in harvested leaves. In an additional line of research we have employed the promoter of the senescence-induced BFN1 gene as a handle for identifying components of the regulatory mechanism. This gene was shown to be activated during darkinduced senescence of detached leaves, as well as natural senescence. This was shown by following protein accumulation and promoter activity which demonstrated that this promoter is activated during dark-induced senescence. Analysis of the promoter established that, at least some of the regulatory sequences reside in an 80 bps long fragment of the promoter. Overall, progress was made in identification of components with a role in dark-induced senescence in this project. Further studies should be done in order to better understand the function of these components and develop approaches for modulating the progress of senescence in crop plants for the benefit of agriculture.
