RESUMO
BACKGROUND: This prospective study assesses symptoms 3 months after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection compared to test-negative and population controls, and the effect of vaccination prior to infection. METHODS: Participants enrolled after a positive (cases) or negative (test-negative controls) SARS-CoV-2 test, or after invitation from the general population (population controls). After 3 months, participants indicated presence of 41 symptoms and severity of 4 symptoms. Permutation tests were used to select symptoms significantly elevated in cases compared to controls and to compare symptoms between cases that were vaccinated or unvaccinated prior to infection. RESULTS: In total, 9166 cases, 1698 symptomatic but test-negative controls, and 3708 population controls enrolled. At 3 months, 13 symptoms, and severity of fatigue, cognitive impairment, and dyspnea were significantly elevated incases compared to controls. Of cases, 48.5% reported ≥1 significantly elevated symptom compared to 29.8% of test-negative controls and 26.0% of population controls. Effect of vaccination could be determined for cases aged <65 years, and was significantly protective for loss of smell and taste but not for other symptoms. DISCUSSION: Three months after SARS-CoV-2 infection, almost half of cases report symptoms, which was higher than background prevalence and test-negative prevalence. Vaccination prior to infection was protective against loss of smell and taste in cases aged <65 years.

OBJECTIVE: This study aimed to assess the degree of implementation and barriers encountered in the use of a practice guideline for optimal symptom relief for patients with dementia and pneumonia in Dutch nursing homes. METHODS: A process evaluation included assessment of reach, fidelity, and dose delivered using researcher's observations, and dose received was addressed in a question "use of the practice guideline," which the physicians completed for each patient included in the study. Perceived barriers were assessed with a structured questionnaire (response 69%) and semi-structured interviews (n = 14), which were subject to qualitative content analysis. RESULTS: Of the 55 physicians involved in the intervention phase, 87% attended an implementation meeting; 20 physicians joined the study later (reach). The intervention was implemented as planned, and all intervention components were delivered by the researchers (fidelity and dose delivered). Thirty-six physicians included 109 patients. For 81% of the patients, the treating physician stated to have used the guideline (dose received). The guideline was perceived as providing a good overview of current practice, but some physicians had expected a more directive protocol or algorithm. Further, recommended regular observations of symptoms were rarely performed. Physician's often felt that "this is not different from what we usually do," and with the acute illness, there was not always enough time to (re)familiarize with the contents. CONCLUSIONS: The physicians used the practice guideline frequently despite important barriers. Future implementation may involve strategies such as multiple interactive meetings. Further, the greatest potential to alter usual practice should be emphasized, such as using observational instruments. Copyright © 2016 John Wiley & Sons, Ltd.

BACKGROUND: Pneumonia in people with dementia has been associated with severe discomfort. We sought to assess the effectiveness of a practice guideline for optimal symptom relief for nursing home residents with dementia and pneumonia. METHODS: A single-blind, multicenter, cluster randomized controlled trial was conducted in 32 Dutch nursing homes. Outcomes were assessed on the patient level. The main outcome measures were discomfort and symptoms: discomfort (DS-DAT: Discomfort Scale-Dementia of Alzheimer Type), (lack of) comfort (EOLD-CAD: End Of Life in Dementia-Comfort Assessment in Dying), pain (PAINAD: Pain Assessment in Advanced Dementia), and respiratory distress (RDOS: Respiratory Distress Observation Scale). Outcomes were scheduled daily from diagnosis until 10 days later and a final time between 13-15 days from diagnosis by trained observers who were blinded to the intervention and the residents' condition and treatment. In a pre-intervention phase, usual care was provided to all homes. In the intervention phase, matched clusters of homes were randomized to either the control (n = 16) or intervention condition (n = 16). RESULTS: Between 1 January 2012 and 1 May 2015, 464 episodes of pneumonia were included. Outcomes were obtained for 399 episodes in 367 residents. Longitudinal multilevel linear regression analyses were performed on log-transformed outcomes, so coefficients should be interpreted as a ratio, and a coefficient of 1 means no difference. The practice guideline in the intervention phase did not reduce the level of discomfort and symptoms: DS-DAT: 1.11 (95 % CI 0.93-1.31), EOLD-CAD: 1.01 (95 % CI 0.98-1.05), PAINAD: 1.04 (95 % CI 0.93-1.15), RDOS: 1.11 (95 % CI 0.90-1.24). However, in both the intervention and control groups, lack of comfort and respiratory distress gradually decreased during the entire 3.5 years of data collection, and were lower in the intervention phase compared to the pre-intervention phase: DS-DAT: 0.93 (95 % CI 0.85-1.01), EOLD-CAD: 0.98 (95 % CI 0.97-1.00), PAINAD: 0.96 (95 % CI 0.91-1.01), RDOS: 0.92 (95 % CI 0.87-0.98). CONCLUSIONS: When compared to usual care, the practice guideline for optimal symptom relief did not relieve discomfort and symptoms in nursing home residents with dementia and pneumonia. However, discomfort and symptoms decreased gradually throughout the data collection in both the intervention homes and the control homes. An intervention that focuses on creating awareness may be more effective than a physician practice guideline. TRIAL REGISTRATION: The Netherlands National Trial Register (ID number NTR5071 .

OBJECTIVE: This study aimed to develop a practice guideline for a structured and consensus-based approach to relieve symptoms of pneumonia in patients with dementia in nursing homes. METHODS: A five-round Delphi study involving a panel consisting of 24 experts was conducted. An initial version of the practice guideline was developed with leading representatives of Dutch University Medical Centers with a department for elderly care medicine, based on existing guidelines for palliative care. The experts evaluated the initial version, after which we identified topics that reflected the main divergences. The experts rated their agreement with statements that addressed the main divergences on a 5-point Likert scale. Consensus was determined according to pre-defined criteria. The practice guideline was then revised according to the final decisions made by the project group and the representatives. RESULTS: The response rate for the expert panel was 67%. Main divergences included the applicability of guidelines for palliative care to patients with dementia and pneumonia in long-term care and the appropriateness of specific pharmacological treatment of dyspnea and coughing. Moderate consensus was reached for 80% of the statements. Major revisions included adding pharmacological treatment for coughing and recommending opioid rotation in the case of opioid-induced delirium. Two areas of divergent opinion remained: the usefulness of oxygen administration and treatment of rattling breath. The project group made the final decision in these areas. CONCLUSIONS: We developed a mostly consensus-based practice guideline for patients with dementia and pneumonia and mapped controversial issues for future investigation.

Objectives: Different SARS-CoV-2 variants can differentially affect the prevalence of Post Covid-19 Condition (PCC). This prospective study assesses prevalence and severity of symptoms three months after an Omicron infection, compared to Delta, test-negative and population controls. This study also assesses symptomology after reinfection and breakthrough infections. Methods: After a positive SARS-CoV-2 test, cases were classified as Omicron or Delta based on ≥ 85% surveillance prevalence. Three months after enrolment, participants indicated point prevalence for 41 symptoms and severity, using validated questionnaires for four symptoms. PCC prevalence was estimated as the difference in prevalence of at least one significantly elevated symptom, identified by permutation test, in cases compared to population controls. Results: At three months follow-up, five symptoms and severe dyspnea were significantly elevated in Omicron cases (n = 4138) compared to test-negative (n = 1672) and population controls (n = 2762). PCC prevalence was 10·4% for Omicron cases and 17·7% for Delta cases (n = 6855). In Omicron cases, severe fatigue and dyspnea were more prevalent in reinfected than primary infected, while severity of symptoms did not significantly differ between cases with a booster or primary vaccination course. Conclusions: Prevalence of PCC is 41% lower after Omicron than Delta at three months. Reinfection seems associated with more severe long-term symptoms compared to first infection.
RESUMO
Objective: It is unclear how self-reported severe fatigue and difficulty concentrating after SARS-CoV-2 infection relate to objective neuropsychological functioning. The study aimed to compare neuropsychological functioning between individuals with and without these persistent subjective complaints. Method: Individuals with and without persistent severe fatigue (Checklist Individual Strength (CIS) fatigue ≥ 35) and difficulty concentrating (CIS concentration ≥ 18) at least 3 months after SARS-CoV-2 infection were included. Neuropsychological assessment was performed on overall cognitive functioning, attention, processing speed, executive functioning, memory, visuo-construction, and language (18 tests). T-scores -1.5 SD below population normative data (T ≤ 35) were classified as "impaired". Results: 230 participants were included in the study, of whom 22 were excluded from the analysis due to invalid performance. Of the participants included in the analysis, 111 reported persistent complaints of severe fatigue and difficulty concentrating and 97 did not. Median age was 54 years, 59% (n = 126) were female, and participants were assessed a median of 23 months after first infection (IQR: 16-28). With bivariate logistic regression, individuals with persistent complaints had an increased likelihood of slower information processing speed performance on the Stroop word reading (OR = 2.45, 95%CI = 1.02-5.84) compared to those without persistent complaints. Demographic or clinical covariates (e.g. hospitalization) did not influence this association. With linear regression techniques, persistent complaints were associated with lower t-scores on the D2 CP, TMT B, and TMT B|A. There were no differences in performance on the other neuropsychological tests. Conclusions: Individuals with subjective severe fatigue and difficulty concentrating after COVID-19 do not typically demonstrate cognitive impairment on extensive neuropsychological testing.
RESUMO
INTRODUCTION: The risk factors for persistent fatigue and cognitive complaints after infection with SARS-CoV-2 and the underlying pathophysiology are largely unknown. Both clinical factors and cognitive-behavioural factors have been suggested to play a role in the perpetuation of complaints. A neurobiological aetiology, such as neuroinflammation, could be the underlying pathophysiological mechanism for persisting complaints.To unravel factors associated with persisting complaints, VeCosCO will compare individuals with and without persistent fatigue and cognitive complaints >3 months after infection with SARS-CoV-2. The study consists of two work packages. The first work package aims to (1) investigate the relation between persisting complaints and neuropsychological functioning; (2) determine risk factors and at-risk phenotypes for the development of persistent fatigue and cognitive complaints, including the presence of postexertional malaise and (3) describe consequences of persistent complaints on quality of life, healthcare consumption and physical functioning. The second work package aims to (1) determine the presence of neuroinflammation with [18F]DPA-714 whole-body positron emission tomography (PET) scans in patients with persisting complaints and (2) explore the relationship between (neuro)inflammation and brain structure and functioning measured with MRI. METHODS AND ANALYSIS: This is a prospective case-control study in participants with and without persistent fatigue and cognitive complaints, >3 months after laboratory-confirmed SARS-CoV-2 infection. Participants will be mainly included from existing COVID-19 cohorts in the Netherlands covering the full spectrum of COVID-19 acute disease severity. Primary outcomes are neuropsychological functioning, postexertional malaise, neuroinflammation measured using [18F]DPA-714 PET, and brain functioning and structure using (f)MRI. ETHICS AND DISSEMINATION: Work package 1 (NL79575.018.21) and 2 (NL77033.029.21) were approved by the medical ethical review board of the Amsterdam University Medical Centers (The Netherlands). Informed consent is required prior to participation in the study. Results of this study will be submitted for publication in peer-reviewed journals and shared with the key population.

OBJECTIVES: To explore changes in advance care plans of nursing home residents with dementia following pneumonia, and factors associated with changes. Second, to explore factors associated with the person perceived by elderly care physicians as most influential in advance treatment decision making. DESIGN: Secondary analysis of physician-reported PneuMonitor trial data. SETTING AND PARTICIPANTS: The PneuMonitor trial took place between January 2012 and May 2015 in 32 nursing homes across the Netherlands; it involved 429 residents with dementia who developed pneumonia. METHODS: We compared advance care plans before and after the first pneumonia episode. Generalized logistic linear mixed models were used to explore associations of advance care plan changes with the person most influential in decision making, with demographics and indicators of disease progression. Exploratory analyses assessed associations with the person most influential in decision making. RESULTS: For >90% of the residents, advance care plans had been established before the pneumonia. After pneumonia, treatment goals were revised in 15.9% of residents; 72% of all changes entailed refinements of goals. Significant associations with treatment goal changes were not found. Treatment plans changed in 20.0% of residents. Changes in treatment decisions were more likely for residents who were more severely ill (odds ratio 1.5, 95% CI 1.2-1.9) and those estimated to live <3 months (odds ratio 3.3, 95% CI 1.9-5.8). Physicians reported that a family member was often (47.4%) most influential in decision making. Who is most influential was associated with the resident's dementia severity. CONCLUSIONS AND IMPLICATIONS: Overall, changes in advance care plans after pneumonia diagnosis were small, suggesting stability of most preferences or limited dynamics in the advance care planning process. Advance care planning involving family is common for nursing home residents with dementia, but advance care planning with persons with dementia themselves is rare and requires more attention.

The postprandial glycemic response is an important metabolic health factor, which, from laboratory studies, is known to change from low to high over the course of the day, and from which negative health outcomes have been linked to nightly eating. We applied interstitial continuous glucose monitoring to examine the glycemic response to a standardized carbohydrate-rich snack (198 kcal) across the day in a real-life setting. Twenty-four healthy participants (12 men, 12 women, 27-61 y old) consumed the snack nine times during 6 d in a crossover design, altering the time of consumption between morning, afternoon and evening. The snack was consumed in the participant's own environment with a preceding fast of at least 2.5 h between their customary main meals and practices. Linear mixed models were used with fixed effect of timing, and participant as random effect, to assess incremental area under the curve, peak value and time-to-peak of the glycemic response. Overall, the highest glycemic excursions were observed in the morning, while a more dampened but prolonged response was observed in the evening. These findings do not concur with previously published laboratory studies. This implies that results obtained under controlled experimental conditions in laboratories cannot be generalized directly to predict chrononutritional effects on the glycemic response in healthy individuals and their daily routines.

INTRODUCTION: A substantial proportion of individuals infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), report persisting symptoms weeks and months following acute infection. Estimates on prevalence vary due to differences in study designs, populations, heterogeneity of symptoms and the way symptoms are measured. Common symptoms include fatigue, cognitive impairment and dyspnoea. However, knowledge regarding the nature and risk factors for developing persisting symptoms is still limited. Hence, in this study, we aim to determine the prevalence, severity, risk factors and impact on quality of life of persisting symptoms in the first year following acute SARS-CoV-2 infection. METHODS AND ANALYSIS: The LongCOVID-study is both a prospective and retrospective cohort study being conducted in the Netherlands, with a one year follow-up. Participants aged 5 years and above, with self-reported positive or negative tests for SARS-CoV-2 will be included in the study. The primary outcome is the prevalence and severity of persistent symptoms in participants that tested positive for SARS-CoV-2 compared with controls. Symptom severity will be assessed for fatigue (Checklist Individual Strength (CIS subscale fatigue severity)), pain (Rand-36/SF-36 subscale bodily pain), dyspnoea (Medical Research Council (mMRC)) and cognitive impairment (Cognitive Failure Questionnaire (CFQ)). Secondary outcomes include effect of vaccination prior to infection on persistent symptoms, loss of health-related quality of life (HRQoL) and risk factors for persisting symptoms following infection with SARS-CoV-2. ETHICS AND DISSEMINATION: The Utrecht Medical Ethics Committee (METC) declared in February 2021 that the Medical Research Involving Human Subjects Act (WMO) does not apply to this study (METC protocol number 21-124/C). Informed consent is required prior to participation in the study. Results of this study will be submitted for publication in a peer-reviewed journal.

BACKGROUND: We aimed to find the best predictive model for 14-day mortality in antibiotic-treated nursing home residents with dementia and pneumonia by first applying an existing model to the recent PneuMonitor study. Second, we evaluated whether model performance improved by revising variables or adding variables related to recent changes in the care for older people. METHODS: The original prognostic model included gender, respiratory rate, respiratory difficulty, pulse rate, decreased alertness, fluid intake, eating dependency, and pressure sores. This model was applied to 380 recent pneumonia episodes in nursing home residents with dementia, updated by considering revising and/or adding variables, internally validated using bootstrapping, and transformed into a simplified risk score that can be used in clinical practice. Model performance was evaluated by Hosmer-Lemeshow statistics and calibration graphs to assess calibration; and area under the receiver operating characteristic curve (AUC) to assess discrimination. RESULTS: The newer cohort had lower 14-day mortality and was less often dehydrated or malnourished. Median AUC of the original model over the imputed datasets was 0.76 (interquartile range: 0.76-0.77), compared to 0.80 in the old cohort. Extending the model with dehydration, bowel incontinence, increase in eating dependency and cardiovascular history, while removing pressure sores, improved AUC: 0.80 (interquartile range: 0.80-0.81) after internal validation. Calibration remained adequate (Hosmer-Lemeshow statistic: p = .67). CONCLUSIONS: In the newer cohort with less severe illness, model performance of the existing model was adequate, but a new extended model distinguished better between residents at low and high mortality risk.

OBJECTIVES: To describe observations of suffering in patients with dementia from the diagnosis of pneumonia until cure or death. DESIGN: Prospective observational study between January 2012 and May 2014. SETTING: Dutch nursing homes (32). PARTICIPANTS: Nursing home patients with dementia and pneumonia (n = 193). MEASUREMENTS: Independent observers performed observations of patients with dementia scheduled 13 times within the 15 days following diagnosis of pneumonia; twice daily in the first 2 days- to observe discomfort (Discomfort Scale-Dementia of Alzheimer Type; range 0-27), comfort (End Of Life in Dementia-Comfort Assessment in Dying; range 14-42), pain (Pain Assessment in Advanced Dementia; range 0-10), and dyspnea (Respiratory Distress Observation Scale; range 0-16). RESULTS: Observational data were obtained for 208 cases of pneumonia in 193 patients. In 71.2% of cases, patients received 1 or more treatments to relieve symptoms such as antipyretics, opioids, or oxygen; 89.4% received antibiotics. Discomfort was highest 1 day after diagnosis [mean Discomfort Scale-Dementia of Alzheimer Type score 8.1 (standard deviation, SD 5.8)], then declined, and stabilized around day 10 [mean 4.5 (SD 4.1)], or increased in the days preceding death. Observed pain and dyspnea followed a comparable pattern. Discomfort patterns did not differ much between cases treated with and without antibiotics. CONCLUSIONS: Pneumonia in patients with dementia involved elevated levels of suffering during 10 days following diagnosis and in the days preceding death. Overall observed discomfort was low compared with prior Dutch studies, and the number of treatments to relieve symptoms was higher. Future studies should examine whether symptoms of pneumonia can be relieved even more, and what treatments are the most effective.

BACKGROUND: Infections frequently occur in patients with dementia and antibiotics are often prescribed, but may also be withheld. OBJECTIVES: The aim of this systematic review is to provide a systematic overview of the prevalence of antibiotic use, and factors associated with prescribing antibiotics in patients with dementia. DATA SOURCES: A systematic search of MEDLINE, EMBASE, PSYCINFO, CINAHL, and the Cochrane library databases until February 13, 2014 was performed, using both controlled terms and free-text terms. RESULTS: Thirty-seven articles were included. The point prevalence of antibiotic use in patients with dementia ranged from 3.3 to 16.6%. The period prevalence ranged from 4.4 to 88% overall, and from 23.5 to 94% in variable time frames before death; the median use was 52% (median period 14 days) and 48% (median period 22 days), respectively. Most patients with lower respiratory tract infections or urinary tract infections (77-91%) received antibiotic treatment. Factors associated with antibiotic use related to patients, families, physicians, and the healthcare context. More severe dementia and a poor prognosis were associated with less antibiotic use in various countries. Associations with aspiration and illness severity differed by country. CONCLUSIONS AND IMPLICATIONS: Antibiotic use in patients with dementia is substantial, and probably highly associated with the particular healthcare context. Future studies may report antibiotic use by infection type and stage of dementia, and compare cross-nationally.
