The Core Elements of Psychiatric and Mental Health Nursing: Time, Honest Engagement, Therapeutic Relations, Professional Nursing and Lifetime-Perspective.

Defining psychiatric and mental health nursing has been a challenge for decades, and it is still difficult to find a comprehensive definition. We have identified a possibility to clarify psychiatric and mental health nursing based on humanistic philosophy in a general psychiatric care context. The aim was therefore to identify and synthesize the theoretical frameworks from which psychiatric and mental health nursing models are developed. We systematically collected and evaluated articles based on Grounded Theory (GT) methodology regarding psychiatric or mental health nursing. The PRISMA statement for systematic reviews was used and the formal process of synthesis, as a three-step process of identifying first -, second - and third-order themes following the examples of Howell Major and Savin-Baden. The synthesis resulted in a model describing five core elements of psychiatric and mental health nursing: 'professional nursing', 'therapeutic relationships' and 'honest engagement', with time as the all-encompassing theme, including the patients' 'lifetime perspective'. Psychiatric and mental health nursing is a caring support towards recovery, where the patient's lifetime perspective must be in focus during the caring process with a relationship built on an honest engagement. Time is therefore essential for psychiatric and mental health nursing.

The Cerebellar Mutism Syndrome: Risk Assessment, Prevention and Treatment.

Cerebellar mutism syndrome (CMS) has received increasing attention over the last decades as a complication of posterior fossa tumour surgery in children. Risk factors, aetiological aspects, and treatment measures of the syndrome have been investigated, yet the incidence of CMS remains unchanged. Overall, we are currently able to identify patients at risk, but we are unable to prevent it from occurring.Once CMS sets in, several symptomatic pharmacological treatments have been suggested, but only in smaller case series and not in randomized controlled trials, and it is not clear whether the treatment or time itself had a helpful effect.Within weeks to months, most patients regain their ability to speak after a phase with mutism or severely reduced speech; however, many patients continue to have speech and language deficits. At this point, anti-cancer treatment with chemotherapy and radiotherapy may be of focus more than the prognosis of CMS; however, many patients continue to have speech and language problems for months and years to come, and they are at high risk of other neurocognitive sequelae as well.Without reliable measures to prevent or treat the syndrome, we may look towards improving the prognosis of speech and neurocognitive functioning in these patients. As speech and language impairment is the cardinal symptom and late effect of CMS, the effect of intense and early-onset speech and language therapy as a standard of care in these patients should be investigated in relation to its effect on regaining speech capacity.

Hippocampal Atrophy Subtypes of Alzheimer's Disease Using Automatic MRI in a Memory Clinic Cohort: Clinical Implications.

INTRODUCTION: One pathological hallmark of Alzheimer's disease (AD) is atrophy of medial temporal brain regions that can be visualized on magnetic resonance imaging (MRI), but not all patients will have atrophy. The aim was to use MRI to categorize patients according to their hippocampal atrophy status and to present prevalence of the subtypes, difference in clinical symptomatology and progression, and factors associated with hippocampal subtypes. METHODS: We included 215 patients with AD who had been assessed with the clinically available MRI software NeuroQuant (NQ; CorTechs labs/University of California, San Diego, CA, USA). NQ measures the hippocampus volume and calculates a normative percentile. Atrophy was regarded to be present if the percentile was ≤5. Demographics, cognitive measurements, AD phenotypes, apolipoprotein E status, and results from cerebrospinal fluid and amyloid positron emission tomography analyses were included as explanatory variables of the hippocampal subtypes. RESULTS: Of all, 60% had no hippocampal atrophy. These patients were younger and less cognitively impaired concerning global measures, memory function, and abstraction but impaired concerning executive, visuospatial, and semantic fluency, and more of them had nonamnestic AD, compared to those with hippocampal atrophy. No difference in progression rate was observed between the two groups. In mild cognitive impairment patients, amyloid pathology was associated with the no hippocampal atrophy group. CONCLUSION: The results have clinical implications. Clinicians should be aware of the large proportion of AD patients presenting without atrophy of the hippocampus as measured with this clinical MRI method in the diagnostic set up and that nonamnestic phenotypes are more common in this group as compared to those with atrophy. Furthermore, the findings are relevant in clinical trials.

Multimodal imaging improves brain age prediction and reveals distinct abnormalities in patients with psychiatric and neurological disorders.

The deviation between chronological age and age predicted using brain MRI is a putative marker of overall brain health. Age prediction based on structural MRI data shows high accuracy in common brain disorders. However, brain aging is complex and heterogenous, both in terms of individual differences and the underlying biological processes. Here, we implemented a multimodal model to estimate brain age using different combinations of cortical area, thickness and sub-cortical volumes, cortical and subcortical T1/T2-weighted ratios, and cerebral blood flow (CBF) based on arterial spin labeling. For each of the 11 models we assessed the age prediction accuracy in healthy controls (HC, n = 750) and compared the obtained brain age gaps (BAGs) between age-matched subsets of HC and patients with Alzheimer's disease (AD, n = 54), mild (MCI, n = 90) and subjective (SCI, n = 56) cognitive impairment, schizophrenia spectrum (SZ, n = 159) and bipolar disorder (BD, n = 135). We found highest age prediction accuracy in HC when integrating all modalities. Furthermore, two-group case-control classifications revealed highest accuracy for AD using global T1-weighted BAG, while MCI, SCI, BD and SZ showed strongest effects in CBF-based BAGs. Combining multiple MRI modalities improves brain age prediction and reveals distinct deviations in patients with psychiatric and neurological disorders. The multimodal BAG was most accurate in predicting age in HC, while group differences between patients and HC were often larger for BAGs based on single modalities. These findings indicate that multidimensional neuroimaging of patients may provide a brain-based mapping of overlapping and distinct pathophysiology in common disorders.

Neuropsychiatric symptoms and comorbidity: Associations with dementia progression rate in a memory clinic cohort.

OBJECTIVES: Neuropsychiatric symptoms (NPS) are associated with dementia severity and progression rate. NPS clusters have different neurobiological underpinnings; therefore, their effect on dementia progression may differ. Furthermore, little is known about whether individual comorbidities affect progression rate. We investigated the effect of NPS clusters and individual comorbidities on dementia progression. METHODS: A memory clinic cohort with all-cause dementia (N = 442) was followed for up to 3 years from diagnosis. Previously, we found trajectory groups of dementia progression in this cohort: one with slow progression and two with rapid progression. In the present study, using principal component analysis, three symptom clusters of NPS were identified on the Neuropsychiatric Inventory Questionnaire (NPI-Q): agitation, affective and psychosis symptom clusters. Data regarding comorbidity were collected by linkage to the Norwegian Patient Registry. Multinomial logistic regression was applied to explore the association between NPS clusters and comorbidity with trajectory-group membership. RESULTS: Adjusted for demographics, dementia aetiology, comorbidity and cognition, we found that, at the time of dementia diagnosis, for every point within the psychosis symptom cluster of the NPI-Q, the risk of rapid progression increased by 53%; for every point within the affective symptom cluster, the risk of rapid progression increased by 29%. A previous diagnosis of mental and behavioural disorders (excluding dementia) decreased the risk of rapid dementia progression by 65%. CONCLUSIONS: Psychosis and affective symptom clusters at the time of diagnosis were associated with rapid progression of dementia. Previous diagnoses of mental and behavioural disorders (excluding dementia) were associated with slow progression.

Trajectories and risk factors of dementia progression: a memory clinic cohort followed up to 3 years from diagnosis.

OBJECTIVES: Patients with dementia follow different trajectories of progression. We aimed to investigate which factors at the time of diagnosis could predict trajectory group membership. DESIGN: Longitudinal observational study. SETTING: Specialized memory clinic, Oslo University Hospital in Norway. PARTICIPANTS: Patients assessed at the memory clinic, between 12 January 2009 and 31 July 2016, who were registered in the Norwegian Registry of persons assessed for cognitive symptoms (NorCog) and diagnosed with dementia after the baseline examination period (n = 442). The patients were followed up to 3 years, with an average of 3.5 examinations. MEASUREMENTS: Clinical Dementia Rating Scale Sum of Boxes (CDR-SB), Mini-Mental State Examination (MMSE), the Consortium to Establish a Registry of Alzheimer's disease (CERAD) 10-item word list delayed recall, the Clock Drawing Test, (CDT) Trail Making Test A (TMT-A), and Neuropsychiatric Inventory Questionnaire (NPI-Q). Based on changes in scores on the CDR-SB, we used group-based trajectory modeling (GBTM) to explore the presence of trajectory groups. Multinomial logistic regression was used to explore whether a set of baseline variables could predict trajectory group membership. RESULTS: Three trajectory groups were identified, one with a slow progression rate and two with more-rapid progression. Rapid progression was associated with older age, lower cognitive function (MMSE and TMT-A), and more-pronounced neuropsychiatric symptoms (NPI-Q) at the time of diagnosis. CONCLUSIONS: Our findings demonstrate the heterogeneity of dementia progression and describe risk factors for rapid progression, emphasizing the need for individual follow-up regimes. For future intervention studies, our results may guide the selection of patients.

Neuropsychiatric symptoms and brain morphology in patients with mild cognitive impairment and Alzheimer's disease with dementia.

We present associations between neuropsychiatric symptoms (NPS) and brain morphology in a large sample of patients with mild cognitive impairment (MCI) and Alzheimer's disease with dementia (AD dementia).Several studies assessed NPS factor structure in MCI and AD dementia, but we know of no study that tested for associations between NPS factors and brain morphology. The use of factor scores increases parsimony and power. For transparency, we performed an additional analysis with selected Neuropsychiatric Inventory - Questionnaire (NPI-Q) items. Including regional cortical thickness, cortical and subcortical volumes, we examined associations between NPS and brain morphology across the whole brain in an unbiased fashion. We reported both statistical significance and effect sizes, using linear models adjusted for multiple comparisons by false discovery rate (FDR). Moreover, we included an interaction term for diagnosis and could thereby compare associations of NPS and brain morphology between MCI and AD dementia.We found an association between the factor elation and thicker right anterior cingulate cortex across MCI and AD dementia. Associations between the factors depression to thickness of the banks of the left superior temporal sulcus and psychosis to the left post-central volume depended on diagnosis: in MCI these associations were positive, in AD dementia negative.Our findings indicate that NPS in MCI and AD dementia are not exclusively associated with atrophy and support previous findings of associations between NPS and mainly frontotemporal brain structures. OBJECTIVES: Neuropsychiatric symptoms (NPS) are common in mild cognitive impairment (MCI) and Alzheimer's disease with dementia (AD dementia), but their brain structural correlates are unknown. We tested for associations between NPS and MRI-based cortical and subcortical morphometry in patients with MCI and AD dementia. DESIGN: Cross-sectional. SETTINGS: Conducted in Norway. PARTICIPANTS: Patients with MCI (n = 102) and AD dementia (n = 133) from the Memory Clinic and the Geriatric Psychiatry Unit at Oslo University Hospital. MEASUREMENTS: Neuropsychiatric Inventory ­ Questionnaire (NPI-Q) severity indices were reduced using principal component analysis (PCA) and tested for associations with 170 MRI features using linear models and false discovery rate (FDR) adjustment. We also tested for differences between groups. For transparency, we added analyses with selected NPI-Q items. RESULTS: PCA revealed four factors: elation, psychosis, depression, and motor behavior.FDR adjustment revealed a significant positive association (B = 0.20, pFDR < 0.005) between elation and thickness of the right caudal anterior cingulate cortex (ACC) across groups, and significant interactions between diagnosis and psychosis (B = −0.48, pFDR < 0.0010) on the left post-central volume and between diagnosis and depression (B = −0.40, pFDR < 0.005) on the thickness of the banks of the left superior temporal sulcus. Associations of apathy, anxiety, and nighttime behavior to the left temporal lobe were replicated. CONCLUSIONS: The positive association between elation and ACC thickness suggests that mechanisms other than atrophy underly elation. Interactions between diagnosis and NPS on MRI features suggest different mechanisms of NPS in our MCI and AD dementia samples. The results contribute to a better understanding of NPS brain mechanisms in MCI and AD dementia.

The Association Between Circulating Inflammatory Markers and the Progression of Alzheimer Disease in Norwegian Memory Clinic Patients With Mild Cognitive Impairment or Dementia.

OBJECTIVE: Neuroinflammation may play an important role in the pathogenesis and progression of Alzheimer disease (AD). The aim of the present study was to detect whether increased inflammatory activity at baseline could predict cognitive and functional decline in patients with amnestic mild cognitive impairment (aMCI) or AD dementia after 2 years. METHODS: Serum samples from 242 memory clinic patients with an aMCI (n=88) or AD dementia (n=154) were analyzed for C-reactive protein and for 14 other inflammatory markers [interleukin (IL)-1ß, interleukin-1 receptor antagonist, IL-6, IL-10, IL-12p40, IL-17a, IL-18, IL-22, IL-33, tumor necrosis factor, cluster of differentiation 40 ligand, interferon-γ, chemokine ligand (CCL) 2, and CCL4] by bead-based multiplex immunoassay. Disease progression was measured by the annual increase in the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) and annual decrease in the score on the Mini-Mental State Examination (MMSE). RESULTS: No association between increased levels of the inflammatory markers and change on the CDR-SB or MMSE score was found, but there was a significant difference in baseline IL-6 and interleukin-1 receptor antagonist levels between aMCI and AD dementia groups. CONCLUSION: Increased levels of inflammatory markers were not associated with faster progression as measured by the annual change on the CDR-SB or MMSE score.

Applicability of the locus of control of behaviour scale for people with dementia.

OBJECTIVE: To investigate the applicability of the Locus of Control of Behaviour scale (LoCB) for people with dementia. METHOD: A sample of 534 participants with dementia (78.4 mean age, 58% female) were included. Assessment included the LoCB, the Montgomery-Aasberg Depression Rating Scale (MADRS), the Mini-Mental Status Examination Norwegian revised (MMSE-NR) and the Instrumental Activities of Daily Living (I-ADL). Completion percentages and internal reliability of LoCB were examined for predefined MMSE-NR groups (0-4, 5-9, 10-14, 15-19, 20-24, 25-27, and 28-30). Factors associated with completion were analysed, and a principal component analysis (PCA) of the LoCB was performed. Sum score and component subscale scores were compared to MADRS and MMSE-NR scores. RESULTS: In total, 234 participants completed the LoCB. Completion percentages ranged from 74% (MMSE-NR 28-30) to 0% (MMSE-NR 0-9). Internal reliability was between 0.80 and 0.72 in groups with MMSE-NR > 9, except in MMSE-NR 20-24 (0.52). Age, MMSE-NR and education were associated with completion. The PCA yielded three components - powerful others, internal, and luck/fate - with explained variance of 41.3%. Participants with MADRS > 7 scored higher on the LoCB sum score, powerful others and internal subscale scores. No difference was found regarding the luck/fate subscale score. MMSE-NR did not affect LoCB scores. CONCLUSION: Older age, less education, and more cognitive impairment decreased the likelihood of completion. However, psychometric test results indicate that those who completed the LoCB understood the questions, even with severe cognitive impairment. We conclude, therefore, that the LoCB is applicable for investigating control orientation among people with dementia.

Burdens experienced and perceived needs of relatives of persons with SMI - a systematic meta-synthesis.

Background: Close relatives of people with severe mental illness (SMI) experience problems known as family burdens. In addition, they may have their own needs for support, something often overlooked by the healthcare system. Meta-syntheses in this area may help explore the meaning of the experience of living with someone who has a SMI.Aim: Our aim was to describe the burdens experienced and needs perceived on a daily basis by relatives to someone who has a SMI.Methods: The databases PubMed, CINAHL, and PsychInfo were searched using a systematic search strategy. Studies were screened for relevance and quality was appraised. A meta-synthesis of nine qualitative studies was then conducted.Results: The nine studies discerned the following themes. Burden themes; Forced to carry a sometimes unbearable burden; Burdened by own ill-health and disrupted relationships; Distressed and stigmatized by society. Needs themes; strengthening protective factors; Skills and practical support greatly appreciated.Conclusions: The burdens and needs of relatives of persons with SMI strongly influence their lives. They require relief from both practical and emotional burdens. Family interventions and other programs to support relatives should be encouraged with this knowledge in mind.

The Loss in Expectation of Life due to Early-Onset Mild Cognitive Impairment and Early-Onset Dementia in Norway.

INTRODUCTION: Whether patients with early-onset dementia have poorer or improved survival compared with those with a late onset largely depends on the survival measure. Survival estimates for early-onset mild cognitive impairment (MCI) diagnosis are particularly scarce. We aimed to estimate life expectancy (LE) in patients with early-onset dementia or early MCI, and loss in expectation of life (LEL) for these groups. Comparisons were made with the general Norwegian population and a subgroup of patients with late-onset dementia. METHODS: Early onset was defined as receiving a diagnosis of MCI or dementia before age 65 years. LE and LEL were predicted using flexible parametric survival models. Our study population was comprised of newly diagnosed (incident) cases (n = 4,906), aged 50-90 years at the time of diagnosis (672 were diagnosed before age 65 years, of which 291 were diagnosed with dementia), in the Norwegian register of persons assessed for cognitive symptoms (NorCog) between 2009 and 2017, and patients were followed up for mortality or censorship until January 2018. RESULTS: Among the early-onset patients, 8 and 23% died during follow-up, in the MCI and dementia groups, respectively. Both early-onset MCI and especially early-onset dementia were associated with lower LE than in the general Norwegian population; LE for 60-year-old women in 2016 was 26 years in the general population, 20 years in MCI patients, and 7 years in dementia patients. The corresponding LE at 80 years was 10, 6, and 5 years. Thus, LEL were particularly pronounced for patients with early dementia. The diagnosis-specific LE pattern in men was similar to that in women. DISCUSSION: Early-onset MCI was associated with substantial life years lost (5-6 years), but the loss was particularly pronounced for those with early-onset dementia, reducing the expected life length by 2 decades.

Cortisol levels among older people with and without depression and dementia.

Cortisol dysregulation has been reported in dementia and depression. Cortisol levels and its associates were investigated among older people living at home and in nursing homes, in a cross-sectional study. A sample of 650 older people, from the community (home and nursing homes) and specialized care (memory clinics and old age psychiatry wards), mean age 76.8 (SD = 10.3) (dementia n = 319, depression, n = 154, dementia plus depression n = 53, and reference group n = 124), was included. Assessment included the Mini Mental State Examination (MMSE), Cornell scale for depression in dementia, activities of daily living scales, and salivary cortisol. Number of drugs was registered. The results showed that the cortisol ratio was highest among patients with dementia and co-morbid depression in comparison to those with either depression or dementia and the reference group. Characteristics significantly associated with cortisol levels were higher MMSE score (in patients with dementia and co-morbid depression), male gender (in people with dementia), and number of medications (in the reference group). We conclude that the cortisol ratio was highest among patients with dementia and co-morbid depression in comparison to those with either depression or dementia and the reference group. The association of cortisol level with MMSE score among patients with dementia and depression could further indicate that increased stress is related to cognitive function.

FAST-O works well for characterization and monitoring of sheltered housing schizophrenia patients.

OBJECTIVE: The de-institutionalizing process came to an end before the millennium shift by closing mental hospitals. After that some of the most ill patients are cared for in sheltered housing (SH). There is no in-house psychiatric competence and the staff on the floor usually lacks such knowledge and training. Observation instruments may improve this by making it possible to assess and monitor patients. METHOD: FAST-O is a simple twelve-item observation scale. Staff at eight SH units were trained in using the instrument and then assessed a total of 67 patients once, twice or three times at monthly intervals. RESULTS: Ten items formed two highly homogenous subscales reflecting Social skills (Soc) and Excitation/Aggression (E/A). Depression and Clinical Global Impression (CGI) items were considered separately. The correlation pattern suggested that the ratings had construct validity. A cluster analysis identified three patient subgroups, of which one had very high E/A scores. Comparisons with reference data suggested that the average symptom level was on par with acutely admitted in-patients for this subgroup. In all groups, E/A symptoms varied considerably over time, the other symptoms were more stable. There were marked differences among the eight SH units with respect to the level of patient problems. CONCLUSIONS: The SH staff was able to produce valid FAST-O assessments. There are reference data which makes it possible to characterize individual patients as well as SH units with respect to treatment needs and safety aspects (for instance risk of violence).

A Mismatch of Paradigms Disrupts the Introduction of Psycho-Educative Interventions for Families of Persons with SMI: An Interview Study with Staff from Community Services.

Treatment and support of people diagnosed with severe mental illness in Sweden takes place in out-patient psychiatric services or municipality services. Most of the responsibility for support in daily life are provided by the close family. One crucial matter is how to support these families. This research project aimed to investigate the Swedish construction with shared responsibility between county psychiatric care and municipality social care for consumers with severe mental illness affects actions in municipalities in relation to family support. Ten representatives from five municipality settings were interviewed. Five semi-structured interviews were analysed using a thematic analysis. The following themes emerged; One overarching theme, "a mismatch of paradigms", and sub-themes: (a) "accentuating differences", (b) "doubts about including the entire family in the same session" and (c) "lack of a uniform family support policy". We conclude that a shared mandate needs a dialogue between psychiatric and municipality services concerning this mismatch.

Association between vascular comorbidity and progression of Alzheimer's disease: a two-year observational study in Norwegian memory clinics.

BACKGROUND: Vascular risk factors increase the risk of Alzheimer's disease (AD), but there is limited evidence on whether comorbid vascular conditions and risk factors have an impact on disease progression. The aim of this study was to examine the association between vascular disease and vascular risk factors and progression of AD. METHODS: In a longitudinal observational study in three Norwegian memory clinics, 282 AD patients (mean age 73.3 years, 54% female) were followed for mean 24 (16-37) months. Vascular risk factors and vascular diseases were registered at baseline, and the vascular burden was estimated by the Framingham Stroke Risk Profile (FSRP). Cerebral medical resonance images (MRIs) were assessed for white matter hyperintensities (WMH), lacunar and cortical infarcts. The associations between vascular comorbidity and progression of dementia as measured by annual change in Clinical Dementia Rating Sum of Boxes (CDR-SB) scores were analysed by multiple regression analyses, adjusted for age and sex. RESULTS: Hypertension occurred in 83%, hypercholesterolemia in 53%, diabetes in 9%, 41% were overweight, and 10% were smokers. One third had a history of vascular disease; 16% had heart disease and 15% had experienced a cerebrovascular event. MRI showed lacunar infarcts in 16%, WMH with Fazekas score 2 in 26%, and Fazekas score 3 in 33%. Neither the vascular risk factors and diseases, the FSRP score, nor cerebrovascular disease was associated with disease progression in AD. CONCLUSIONS: Although vascular risk factors and vascular diseases were prevalent, no impact on the progression of AD after 2 years was shown.

Comparison of automated volumetry of the hippocampus using NeuroQuant® and visual assessment of the medial temporal lobe in Alzheimer's disease.

Background Different clinically feasible methods for evaluation of medial temporal lobe atrophy exists and are useful in diagnostic work-up of Alzheimer's disease (AD). Purpose To compare the diagnostic properties of two clinically available magnetic resonance imaging (MRI)-based methods-an automated volumetric software, NeuroQuant® (NQ) (evaluation of hippocampus volume) and the Scheltens scale (visual evaluation of medial temporal lobe atrophy [MTA])-in patients with AD dementia, and subjective and mild cognitive impairment (non-dementia). Material and Methods MRIs from 56 patients (31 AD, 25 non-dementia) were assessed with both methods. Correlations between the methods were calculated and receiver operating curve (ROC) analyses that yield area under the curve (AUC) statistics were conducted. Results High correlations were found between the two MRI assessments for the total hippocampal volume measured with NQ and mean MTA score (-0.753, P < 0.001), for the right (-0.767, P < 0.001), and for the left (-0.675, P < 0.001) sides. The NQ total measure yielded somewhat higher AUC (0.88, "good") compared to the MTA mean measure (0.80, "good") in the comparison of patients with AD and non-dementia, but the accuracy was in favor of the MTA scale. Conclusion The two methods correlated highly and both methods reached equally "good" power.

Sociodemographic, physical, mental and social factors in the cessation of breastfeeding before 6 months: a systematic review.

BACKGROUND: The World Health Organization recommends exclusive breastfeeding as the main source of nutrition for infants during their first 6 months of life. However, despite this well-known recommendation, not all mothers breastfeed, whether partly or fully, during this time. OBJECTIVE: The aim of this systematic literature review was to compile evidence regarding sociodemographic, physical, mental and social factors that influence breastfeeding mothers to stop breastfeeding before the infant reaches 6 months. SEARCH METHOD: A systematic search was conducted in four databases. SELECTION CRITERIA: Studies with quantitative research were included. DATA COLLECTION AND ANALYSIS: Totally, 186 abstracts were read, 83 seemed relevant but 18 were found to be duplicates. Finally, 27 articles met the inclusion criteria and were included. The quality assessment was carried out with a quality assessment template from the Swedish Council on Technology and Assessment, and the grading of the result was carried out according to GRADE. RESULTS: The association of breastfeeding cessation between the mother's young age, low level of education, return to work within 12-week postpartum, caesarean birth and inadequate milk supply was found to have a low level of evidence. The link found between depressions among the mothers with the cessation of breastfeeding was found to have a very low level of evidence. CONCLUSIONS: Sociodemographic factors appeared to have caused cessation of breastfeeding in some of the included articles. The preventive work should focus on how to improve the knowledge of healthcare professionals and targeted interventions must address mothers who are at risk of ceasing breastfeeding before the recommended time.

Nurses' experiences of caring for patients with intellectual developmental disorders: a systematic review using a meta-ethnographic approach.

BACKGROUND: Research suggests that registered nurses (RNs) do not feel adequately prepared to support patients with intellectual disability disorder (IDD). This is unsurprising, as few European health sciences curricula include undergraduate and graduate training courses in IDD. As RNs are often in the front line of care, eliciting in-depth knowledge about how they experience nursing this group of patients is vital. Our aim in this study was to develop a conceptual understanding about RNs' experiences of nursing patients with IDD. METHOD: We undertook a systematic review and meta-ethnography to synthesise qualitative research studies found in PubMed, CINAHL, PsycINFO, ERIC databases and by manual searching to identify additional studies. We condensed translatable second-order constructs, and developed an idiomatic translation. Finally, we formulated line of argument (LOA) syntheses to capture the core of the idiomatic translations. RESULTS: We included eighteen published studies from eight countries involving 190 RNs. The RNs' experience of nursing patients with IDD were reflected in 14 LOAs. Six of these reflected a tentatively more distinctive and at times unique conceptualisation of RNs' experience of nursing this group of patients. The remaining eight LOAs represented a conceptualisation of nursing per se, a conceptualisation of nursing that was interpreted as a universal experience regardless of context and patient group. CONCLUSION: Lack of awareness and knowledge are likely breeding grounds for the 'otherness' that still surrounds this group of patients. In encounters between patients and RNs, focusing on the person behind the disability label could be one way to secure relevant nursing care for patients with IDD. Undertaking appropriate under- and postgraduate education alongside the implementation of nursing models focusing on patient-centred care would help RNs in reducing the health and care inequalities this group of patients still face.

Distinguishing early and late brain aging from the Alzheimer's disease spectrum: consistent morphological patterns across independent samples.

Alzheimer's disease (AD) is a debilitating age-related neurodegenerative disorder. Accurate identification of individuals at risk is complicated as AD shares cognitive and brain features with aging. We applied linked independent component analysis (LICA) on three complementary measures of gray matter structure: cortical thickness, area and gray matter density of 137 AD, 78 mild (MCI) and 38 subjective cognitive impairment patients, and 355 healthy adults aged 18-78 years to identify dissociable multivariate morphological patterns sensitive to age and diagnosis. Using the lasso classifier, we performed group classification and prediction of cognition and age at different age ranges to assess the sensitivity and diagnostic accuracy of the LICA patterns in relation to AD, as well as early and late healthy aging. Three components showed high sensitivity to the diagnosis and cognitive status of AD, with different relationships with age: one reflected an anterior-posterior gradient in thickness and gray matter density and was uniquely related to diagnosis, whereas the other two, reflecting widespread cortical thickness and medial temporal lobe volume, respectively, also correlated significantly with age. Repeating the LICA decomposition and between-subject analysis on ADNI data, including 186 AD, 395 MCI and 220 age-matched healthy controls, revealed largely consistent brain patterns and clinical associations across samples. Classification results showed that multivariate LICA-derived brain characteristics could be used to predict AD and age with high accuracy (area under ROC curve up to 0.93 for classification of AD from controls). Comparison between classifiers based on feature ranking and feature selection suggests both common and unique feature sets implicated in AD and aging, and provides evidence of distinct age-related differences in early compared to late aging.

Cerebellar mutism syndrome in children with brain tumours of the posterior fossa.

BACKGROUND: Central nervous system tumours constitute 25% of all childhood cancers; more than half are located in the posterior fossa and surgery is usually part of therapy. One of the most disabling late effects of posterior fossa tumour surgery is the cerebellar mutism syndrome (CMS) which has been reported in up to 39% of the patients but the exact incidence is uncertain since milder cases may be unrecognized. Recovery is usually incomplete. Reported risk factors are tumour type, midline location and brainstem involvement, but the exact aetiology, surgical and other risk factors, the clinical course and strategies for prevention and treatment are yet to be determined. METHODS: This observational, prospective, multicentre study will include 500 children with posterior fossa tumours. It opened late 2014 with participation from 20 Nordic and Baltic centres. From 2016, five British centres and four Dutch centres will join with a total annual accrual of 130 patients. Three other major European centres are invited to join from 2016/17. Follow-up will run for 12 months after inclusion of the last patient. All patients are treated according to local practice. Clinical data are collected through standardized online registration at pre-determined time points pre- and postoperatively. Neurological status and speech functions are examined pre-operatively and postoperatively at 1-4 weeks, 2 and 12 months. Pre- and postoperative speech samples are recorded and analysed. Imaging will be reviewed centrally. Pathology is classified according to the 2007 WHO system. Germline DNA will be collected from all patients for associations between CMS characteristics and host genome variants including pathway profiles. DISCUSSION: Through prospective and detailed collection of information on 1) differences in incidence and clinical course of CMS for different patient and tumour characteristics, 2) standardized surgical data and their association with CMS, 3) diversities and results of other therapeutic interventions, and 4) the role of host genome variants, we aim to achieve a better understanding of risk factors for and the clinical course of CMS - with the ultimate goal of defining strategies for prevention and treatment of this severely disabling condition.
