Background: Dysphagia is common after stroke, requiring exclusive enteral feeding in 20% of patients. Recovery of oral feeding is associated with increased quality of life, better functional ...outcomes, and decreased mortality rates. However, evidence is heterogeneous and not conclusive on which factors are predictive of oral feeding recovery for stroke patients in rehabilitation units. Aim: To investigate predictors of complete oral feeding recovery. Design: Retrospective study. Setting: Intensive inpatient rehabilitation hospital. Population: Poststroke dysphagic individuals with enteral feeding. Methods: Retrospective chart review of demographic, clinical, rehabilitation, and swallowing factors. Univariate analysis and multivariate regression analysis were used to compare variables between the oral feeding recovery group and the enteral feeding group at discharge. Results: One hundred thirty-nine patients were included in the analysis. A total of 61.9% of the sample population resumed complete oral intake at discharge. There were statistically significant differences between the 2 groups in Functional Independence Measure cognitive score, clinical swallow evaluation, and instrumental swallow evaluation at admittance, and dysphagia rehabilitation. Multiple logistic regression analysis identified the absence of aspiration signs with liquids associated with a higher probability of the resumption of complete oral feeding (odds ratio OR 3.57; 95% confidence interval CI 1.07-11.89). Age between 73 and 79 years (OR .96; 95% CI .01-.58), the presence of aspiration and/or penetration (OR .22; 95% CI .07-.72), and the presence of residue (OR .14; 95%CI .04-.43) during fiberoptic endoscopic evaluation of swallowing presented lower probability of returning to complete oral feeding. Conclusion: Several demographic and swallowing characteristics predicted oral feeding recovery. Absence of dysphagia signs documented on fiberoptic endoscopic evaluation of swallowing was the strongest predictor of complete oral feeding resumption.
Background
The occurrence of dementia among individuals with a migration background and composing ethnic minorities is being recognized as a global public health issue.
Aims
In the present study, we ...sought to explore if and how this phenomenon is mentioned and addressed by the existing National Dementia Plans (NDPs).
Methods
The 32 NDPs listed on the Alzheimer’s Disease International (ADI)’s website were considered for the present analysis. First, the plans mentioning the issue of dementia among migrants and/or ethnic minorities were identified. Subsequently, the sections addressing this topic and the pertaining proposed actions were analyzed and their contents were unbundled in descriptive categories.
Results
Overall, nine NDPs (28.1% of the total), namely those promulgated by Australia, Austria, England, Israel, Norway, Switzerland, Taiwan, United States, and Wales, mentioned the issue of dementia among migrants and/or ethnic minorities and only eight proposed targeted actions to tackle this issue. With few exceptions, the proposed strategies were only marginally dashed within NDPs and crucial information on their objectives, timeline, conduction, and monitoring was missing.
Discussion and conclusions
To our knowledge, this is the first attempt to describe and discuss how the issue of dementia among migrants and ethnic minority groups is addressed within NDPs. The issue of dementia in migrants and ethnic minorities is assuming a growing relevance under a of global health perspective. The timely identification and implementation of dedicated policies at the national and international level are fundamental to limit its future clinical and socioeconomic burden.
Dementias are chronic, degenerative neurological disorders with a complex management that require the cooperation of different healthcare professionals. The Italian Ministry of Health produced the ...document “Guidance on Integrated Care pathway for People with Dementia” (GICPD) with the specific objective of providing a standardized framework for the definition, development, and implementation of integrated care pathways (ICP) dedicated to people with dementia. We searched all available Italian territorial ICPs. Two raters assessed the retrieved ICPs with a 2-point scale on a 43-item checklist based on the GICPD. Only 5 out of 21 regions and 5 out of 101 local health authorities had an ICP, with most ICPs having a moderate compliance to the GICPD, in particular for the items referring to the development and implementation of the care pathways. A low to moderate inter-rater agreement was observed, mainly due to a lack of standardized models to describe ICPs for dementias. Results suggest that policy- and decision-makers should pay more attention to the GICPD when producing ICPs. The direct communication with clinicians, and the implementation of more precise and appropriate clinical outcomes, could increase the involvement of clinicians, whose participation is crucial to guarantee that ICPs meet needs of patients and their carers.
Abstract
Background
The locations where children get exposed to SARS-CoV-2 infection and their contribution in spreading the infection are still not fully understood. Aim of the article is to verify ...the most frequent reasons for SARS-CoV-2 infection in children and their role in the secondary transmission of the infection.
Methods
A case-control study was performed in all SARS-CoV-2 positive children (
n
= 81) and an equal number of age- and sex- matched controls who were referred to the S. Camillo-Forlanini Pediatric Walk-in Center of Rome. The results of all SARS-CoV-2 nasopharyngeal swabs performed in children aged < 18 years from October 16 to December 19, 2020 were analyzed.
Results
School contacts were more frequent in controls than in cases (OR 0.49; 95% CI: 0.3–0.9), while household contacts were higher in cases (OR 5.09; 95% CI: 2.2–12.0). In both cases and controls, school contacts were significantly less frequent, while on the contrary household contacts seemed to be more frequent in nursery school children compared to primary school or middle/high school children. A multivariate logistic regression showed that the probability of being positive to SARS-CoV-2 was significantly lower in children who had school contacts or who had flu symptoms compared to children who had household contacts. Results showed a 30.6% secondary attack rate for household contacts.
Conclusion
In our study population, the two most frequent reasons for SARS-CoV-2 infection were school and home contacts. The risk of being positive was 5 times lower in children who had school contacts than in children who had household contacts.
Background: Late neurocognitive sequelae are common among long-term brain tumour survivors, resulting in significantly worse quality of life. Cognitive rehabilitation through specific APP/software ...for PC/tablets represents an innovative intervention spreading in recent years. In this study, we aim to review the current evidence and trends regarding these innovative approaches. Methods: A systematic literature review was performed. Inclusion criteria were: (i) Studies recruiting patients diagnosed with any brain tumour before 21 years of age; (ii) studies assessing the role of digital interventions on cognitive outcomes. Case reports, case series, reviews, letters, conference proceedings, abstracts, and editorials were excluded. Results: Overall, nine studies were included; 152 patients (67.8% males) with brain tumours underwent a digital intervention. The mean age at diagnosis and the intervention enrolment ranged from 4.9 to 9.4 years and 11.1 to 13.3 years, respectively. The computer-based software interventions employed were: Cogmed, Captain’s Log, Fast ForWord, and Nintendo Wii. Most of these studies assessed the effects of cognitive training on working memory, attention, and performance in daily living activities. Conclusions: The studies suggest that this type of intervention improves cognitive functions, such as working memory, attention, and processing speed. However, some studies revealed only transient positive effects with a significant number of dropouts during follow-up. Trials with greater sample sizes are warranted. Motivating families and children to complete cognitive interventions could significantly improve cognitive outcomes and quality of life.
Hippocampal volume is one of the main biomarkers of Alzheimer's Dementia (AD). Over the years, advanced tools that performed automatic segmentation of Magnetic Resonance Imaging (MRI) T13D scans have ...been developed, such as FreeSurfer (FS) and ACM-Adaboost (AA). Hippocampal volume is considered abnormal when it is below the 5th percentile of the normative population. The aim of this study was to set norms, established from the Alzheimer's Disease Neuroimaging Initiative (ADNI) population, for hippocampal volume measured with FS v.6.0 and AA tools in the neuGRID platform (www.neugrid2.eu) and demonstrate their applicability for the Italian population.
Norms were set from a large group of 545 healthy controls belonging to ADNI. For each pipeline, subjects with segmentation errors were discarded, resulting in 532 valid segmentations for FS and 421 for AA (age range 56-90 years). The comparability of ADNI and the Italian Brain Normative Archive (IBNA), representative of the Italian general population, was assessed testing clinical variables, neuropsychological scores and normalized hippocampal volumes. Finally, percentiles were validated using the Italian Alzheimer's disease Repository Without Borders (ARWiBo) as external independent data set to evaluate FS and AA generalizability.
Hippocampal percentiles were checked with the chi-square goodness of fit test.
-values were not significant, showing that FS and AA algorithm distributions fitted the data well. Clinical, neuropsychological and volumetric features were similar in ADNI and IBNA (
> 0.01). Hippocampal volumes measured with both FS and AA were associated with age (
< 0.001). The 5th percentile thresholds, indicating left/right hippocampal atrophy were respectively: (i) below 3,223/3,456 mm
at 56 years and 2,506/2,415 mm
at 90 years for FS; (ii) below 4,583/4,873 mm
at 56 years and 3,831/3,870 mm
at 90 years for AA. The average volumes computed on 100 cognitively intact healthy controls (CN) selected from ARWiBo were close to the 50th percentiles, while those for 100 AD patients were close to the abnormal percentiles.
Norms generated from ADNI through the automatic FS and AA segmentation tools may be used as normative references for Italian patients with suspected AD.
This systematic review has been conducted with the aim of characterizing cognitive deficits and analyzing their frequency in survivors of paediatric Central Nervous System tumours.
All literature ...published up to January 2023 was retrieved searching the databases "PubMed", "Cochrane", "APA PsycInfo" and "CINAHL". The following set of pre-defined inclusion criteria were then individually applied to the selected articles in their full-text version: i) Retrospective/prospective longitudinal observational studies including only patients diagnosed with primary cerebral tumours at ≤ 21 years (range 0-21); ii) Studies including patients evaluated for neuro-cognitive and neuro-psychological deficits from their diagnosis and/or from anti-tumoral therapies; iii) Studies reporting standardized tests evaluating patients' neuro-cognitive and neuro-psychological performances; iv) Patients with follow-ups ≥ 2 years from the end of their anti-tumoral therapies; v) Studies reporting frequencies of cognitive deficits.
39 studies were included in the analysis. Of these, 35 assessed intellectual functioning, 30 examined memory domains, 24 assessed executive functions, 22 assessed attention, 16 examined visuo-spatial skills, and 15 explored language. A total of 34 studies assessed more than one cognitive function, only 5 studies limited their analysis on a single cognitive domain. Attention impairments were the most recurrent in this population, with a mean frequency of 52.3% after a median period post-treatment of 11.5 years. The other cognitive functions investigated in the studies showed a similar frequency of impairments, with executive functions, language, visuospatial skills and memory deficits occurring in about 40% of survivors after a similar post-treatment period. Longitudinal studies included in the systematic review showed a frequent decline over time of intellectual functioning.
Survivors of paediatric Central Nervous System tumours experience cognitive sequelae characterized by significant impairments in the attention domain (52.3%), but also in the other cognitive functions. Future studies in this research field need to implement more cognitive interventions and effective, but less neurotoxic, tumour therapies to preserve or improve neurocognitive functioning and quality of life of this population.
Older people living in nursing homes (NHs) are particularly vulnerable in the ongoing COVID-19 pandemic, due to the high prevalence of chronic diseases and disabilities (e.g., dementia). The ...phenomenon of adverse events (AEs), intended as any harm or injury resulting from medical care or to the failure to provide care, has not yet been investigated in NHs during the pandemic. We performed a national survey on 3,292 NHs, either public or providing services both privately and within the national health system, out of the 3,417 NHs covering the whole Italian territory. An online questionnaire was addressed to the directors of each facility between March 24 and April 27, 2020. The list of NHs was provided by the Dementia Observatory, an online map of Italian services for people with dementia, which was one of the objectives of the implementation of the Italian National Dementia Plan. About 26% of residents in the Italian NHs for older people listed within the Dementia Observatory site had dementia. The objective of our study was to report the frequency of AEs that occurred during the months when SARS-CoV-2 spreading rate was at its highest in the Italian NHs and to identify which conditions and attributes were most associated with the occurrence of AEs by means of multivariate regression logistic analysis. Data are referred to 1,356 NHs that participated in the survey. The overall response rate was 41.2% over a time-period of six weeks (from March 24 to May 5). About one third of the facilities (444 out of 1,334) (33.3%) reported at least 1 adverse event, with a total of 2,000 events. Among the included NHs, having a bed capacity higher than the median of 60 beds (OR=1.57, CI95% 1.17-2.09; p=0.002), an observed increased in the use of psychiatric drugs (OR=1.80, CI95% 1.05-3.07; p=0.032), adopting physical restraint measures (OR=1.97, CI95% 1.47-2.64; p<0.001), residents hospitalized due to flu-like symptoms (OR =1.73, CI95% 1.28-2.32; p<0.001), and being located in specific geographic areas (OR=3.59, CI95% 1.81-7.08; OR = 2.90, CI95% 1.45-5.81 and OR = 4.02, CI05% 2.01-8.04 for, respectively, North-West, North-East and Centre vs South, p<0.001) were all factors positively associated to the occurrence of adverse events in the facility. Future recommendations for the management and care of residents in NHs during the COVID-19 pandemic should include specific statements for the most vulnerable populations, such as people with dementia.
The use of biomarkers is profoundly transforming medical research and practice. Their adoption has triggered major advancements in the field of Alzheimer’s disease (AD) over the past years. For ...instance, the analysis of the cerebrospinal fluid (CSF) and neuroimaging changes indicative of neuronal loss and amyloid deposition has led to the understanding that AD is characterized by a long preclinical phase. It is also supporting the transition towards a biology-grounded framework and definition of the disease. Nevertheless, though sufficient evidence exists about the analytical validity (i.e., accuracy, reliability, and reproducibility) of the candidate AD biomarkers, their clinical validity (i.e., how well the test measures the clinical features, and the disease or treatment outcomes) and clinical utility (i.e., if and how the test improves the patient’s outcomes, confirms/changes the diagnosis, identifies at-risk individuals, influences therapeutic choices) have not been fully proven. In the present review, some of the methodological issues and challenges that should be addressed in order to better appreciate the potential benefits and limitations of AD biomarkers are discussed. The ultimate goal is to stimulate a constructive discussion aimed at filling the existing gaps and more precisely defining the directions of future research. Specifically, four main aspects of the clinical validation process are addressed and applied to the most relevant CSF biomarkers: 1) the definition of reference values, 2) the identification of reference standards for the disease of interest (i.e., AD), 3) the inclusion within the diagnostic process, and 4) the statistical process supporting the whole framework.
