Frailty among inpatients with Schizophrenia: Status, influencing factors, and their correlation with quality of life.

This study aimed to understand frailty and its influencing factors in inpatients with Schizophrenia in Chengdu and to explore correlations between frailty and quality of life. From May to July 2022, inpatients with Schizophrenia were surveyed using a general information questionnaire, frailty phenotype (FP) scoring, the Self-Rating Depression Scale (SDS), the Mini-Mental State Examination (MMSE), and the SZ Quality of Life Scale (SQLS). Multivariate logistic regression was conducted to assess factors influencing frailty and multivariate linear regression was conducted to assess the factors influencing quality of life. A total of 556 hospitalized patients with Schizophrenia were included and divided into three groups according to the degree of frailty, of which 153 cases (27.5%) were without frailty, 348 cases (62.6%) were in early frailty, and 55 cases (9.9%) were in frailty. Univariate analysis of age, history of falls during hospitalization, polypharmacy, compulsory treatment during hospitalization, self-reported health status, activity level, cognitive impairment, depressive symptoms, "psychology and society," "motivation and energy" and "symptoms and side-effects" showed statistically significant differences between the groups. Multinomial logistic regression showed that age, BMI, self-reported health, activity, cognitive impairment, motivation and energy, and symptoms and side-effects were influencing factors for frailty in hospitalized patients with Schizophrenia. Correlation analysis shows that frailty score positively correlated with SQLS score. We found that frailty was prevalent and that frailty was positively correlated with SQLS scores in inpatients with Schizophrenia. To effectively manage the frailty of hospitalized patients with Schizophrenia, medical staff should pay attention to its influencing factors and quality of life.

Self-reported hearing loss and cognitive impairment: a cross-sectional analysis of the EpiFloripa Aging study.

This study aimed to investigate the association between self-reported hearing loss and cognitive impairment in older adults in a city in Southern Brazil. In this cross-sectional, population-based cohort study of older adults, data were collected in the third wave of the EpiFloripa Aging study (2017/2019), which had been performed since 2009 in the city of Florianópolis, Santa Catarina State. Cognitive impairment was the dependent variable analyzed by the Mini-Mental State Examination (MMSE), and self-reported hearing loss, which was included in the cohort only in the last wave, was the main exposure variable. Logistic regression analyses were conducted, considering the study design and sample weights. Data from 1,335 older adults were evaluated. The prevalence was 20.5% for cognitive impairment and 10.7% for hearing loss. Older adults with hearing loss were 2.66 (95%CI: 1.08-6.54) times more likely to have cognitive impairment than older adults without hearing loss. The association between hearing loss and cognitive impairment highlights the need to integrate the early identification of these problems into primary care, as both are risk factors for healthy aging and potentially preventable and/or treatable conditions.

Self-reported cognitive impairments and quality of life in patients with gastrointestinal stromal tumor: Results of a multinational survey.

Cancer-related cognitive impairment (CRCI) has long-term effects on survivor quality of life, but CRCI research on patients with gastrointestinal stromal tumor (GIST) is lacking. The aims of this study were to investigate CRCI and concomitant quality of life among patients with GIST. An online survey was used to assess CRCI in adult patients with GIST using the validated Functional Assessment of Cancer Therapy-Cognitive-v.3. Age, education, demographically indexed IQ, general health, and quality of life factors (e.g., fatigue, emotional distress) were also assessed. The online survey was administered through five international GIST and sarcoma support organizations. Over the 3-month recruitment period, the survey was completed by 485 participants: mean age, 57.80 (SD, 11.51), median 5 years after diagnosis. A majority (63.91%) reported experiencing cognitive symptoms with a significant negative quality of life impact. Controlling for age, patients with GIST ≥5 years after diagnosis reported worse cognitive function than those <5 years after diagnosis (p < .05) but did not differ in educational level or IQ. Whereas longer term survivors were more likely to have been treated with tyrosine kinase inhibitor (TKI) therapies, there was no observed association of TKI therapy with self-reported cognitive impairments. A majority of GIST patients report cognitive symptoms that have a negative impact on quality of life, with longer term survivors (≥5 years) tending to report more cognitive impairments. Given the success of TKI therapy to substantially increase overall survival of patients with GIST, addressing CRCI in clinical practice may improve long-term GIST survivor function and quality of life.

Home-Dwelling Older Adults' Day-to-Day Community Interactions: A Qualitative Study.

Background: Many home-dwelling older adults present abnormal behaviours related to dementia or to non-dementia cognitive impairment (e.g., agitation, anxiety, apathy, etc.). Because many older adults live at home alone or are able to hide any signs of abnormal behaviours from others, the non-healthcare workers who interact with older adults on a daily basis are key actors in detecting those behaviours and orienting older adults towards appropriate support services. To the best of our knowledge, no studies to date have explored the daily interactions experienced between older adults and the various non-healthcare workers whom they regularly encounter in the community. This work aimed to identify the non-healthcare workers who are regularly in direct contact with older adults during their day-to-day activities and then develop specific training for these workers on the subject of abnormal behaviours among the elderly. Methods: This qualitative and ethnographic study asked 21 home-dwelling older adults aged 65 years old or more to answer open-ended questions. Sixteen had no self-reported cognitive impairments, and five had a probable or diagnosed slight cognitive impairment or mild-to-moderate dementia. A thematic analysis of the data was carried out. Results: The non-healthcare workers who spent the most time with older adults with and without reported cognitive impairments were those working in cafés or tea rooms and leisure or activity centres. Conclusions: In view of the significant amounts of contact between home-dwelling older adults and non-healthcare workers, it seems necessary and sensible to increase non-healthcare workers’ knowledge about abnormal behaviours, especially by offering them training. The proactive detection and identification of older adults’ abnormal behaviours by non-healthcare workers will ensure earlier care and reduce avoidable hospitalisations, institutionalisations and costs linked to geriatric healthcare.

Effects of cognitive behavioral therapy for insomnia on subjective and objective measures of sleep and cognition

Study objectivesTo assess the effects of Cognitive Behavioral Therapy for insomnia (CBTi) on subjective and objective measures of sleep, sleep-state misperception and cognitive performance. MethodsWe performed a randomized-controlled trial with a treatment group and a wait-list control group to assess changes in insomnia symptoms after CBTi (8 weekly group sessions/3 months) in 62 participants with chronic insomnia. To this end, we conducted a multimodal investigation of sleep and cognition including subjective measures of sleep difficulties (Insomnia Severity Index [ISI]; sleep diaries) and cognitive functioning (Sahlgrenska Academy Self-reported Cognitive Impairment Questionnaire), objective assessments of sleep (polysomnography recording), cognition (attention and working memory tasks), and sleep-state misperception measures, collected at baseline and at 3-months post-randomization. We also assessed ISI one year after CBTi. Our main analysis investigated changes in sleep and cognition after 3 months (treatment versus wait-list). ResultsWhile insomnia severity decreased and self-reported sleep satisfaction improved after CBTi, we did not find any significant change in objective and subjective sleep measures (e.g., latency, duration). Degree of discrepancy between subjective and objective sleep (i.e., sleep misperception) in sleep latency and sleep duration decreased after CBTi suggesting a better perception of sleep after CBTi. In contrast, both objective and subjective cognitive functioning did not improve after CBTi. ConclusionsWe showed that group-CBTi has a beneficial effect on variables pertaining to the subjective perception of sleep, which is a central feature of insomnia. However, we observed no effect of CBTi on measures of cognitive functioning.

Predictors of quality of life among adults with self-reported cancer related cognitive impairment

Objective The purpose of the current study was to examine the unique contribution of personal and medical factors, objective and subjective cognition, and self-efficacy to the explained variance of quality of life (QoL) among survivors with self-reported cancer related cognitive impairment (CRCI). Method Seventy-three cancer survivors (non-central nervous system) with CRCI (mean age: 50.85 ± 10.82 years old, mean years post-treatment: 3 ± 2.7) participated in this cross-sectional study. QoL was assessed using the Functional Assessment of Cancer Therapy (FACT)–GP, while the cognitive function was assessed both objectively using tests of attentional control, speed of processing and sustained attention, and subjectively using the FACT-Cognition perceived cognitive impairments (FACTcog-PCI) subscale. Self-efficacy was assessed using the New General Self-Efficacy Scale (NGSE). Results A hierarchical multiple linear regression analysis revealed that sustained attention, perceived cognitive impairment and self-efficacy, accounted for 54% of the variance of QoL (R 2 = 0.543, p < 0.000), each providing a unique contribution to the explained variance (15–20% each) after controlling for age and gender. Conclusions Considering that these variables may be amenable to change, this model can serve as a conceptual framework for designing effective cognitive treatment options for CRCI. Clinical Trial Registration: ClinicalTrials.gov NCT Implication for rehabilitation Cancer related cognitive impairment is characterized by difficulties in the speed of processing performance, severe perceived cognitive impairments, and relatively low general self-efficacy. Multi-dimensional assessments including subjective and objective cognition as well as self-efficacy should be administered to cancer survivors with cognitive complaints to understand the underlying mechanisms of their QoL. Integrative cognitive rehabilitation interventions that aim to improve QoL among people with cancer-related cognitive impairment should target sustained attention, perceived cognitive impairment, and self-efficacy.

Disentangling self-reported fatigue, depression, and cognitive impairment in people with multiple sclerosis

BackgroundFatigue is a common problem among people with multiple sclerosis (MS) and can have a negative effect on mental, physical, and social function. Self-reported measures of MS fatigue are often operationalized as a multi-dimensional symptom. However, questions remain about how best to account for the multi-dimensional aspects of self-reported fatigue and whether these aspects are distinct entities. Thus, the purpose of this study was to explore the overlap and distinctions between self-reported measures of the severity and impact of fatigue, between mental and physical fatigue, and between mental fatigue, depressive symptoms, and cognitive impairment. MethodsAn observational study was conducted with 289 participants with MS . The questionnaires were the Unidimensional Fatigue Impact Scale (UFIS), the Chalder Fatigue Scale (CFS), the Fatigue Scale for Motor and Cognitive Functions (FSMC), the Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNSQ), and the Quality of Life in Neurological Disorders short form for depression (Neuro-QoL). Spearman's correlation coefficient was used to examine the bivariate correlations between composite and subscale scores. Exploratory structural equation modeling (ESEM) was used to determine the factor structure under a pre-specified number of factors to retain in the modeling of multiple items across questionnaires and examine model fit. Subsequently for poor fitting models in an iterative procedure to determine a better fitting multidimensional model, we posited a bifactor confirmatory factor analysis model. ResultsThe bivariate correlation analysis revealed that subscales from the same questionnaire measuring different aspects of fatigue had the highest correlations (r = 0.61–0.68), subscales from different questionnaires measuring the same aspect of fatigue had the next highest correlations (r = 0.43–0.60), and subscales from different questionnaires measuring different aspects of fatigue had the lowest correlations (r = 0.34–0.40). Bifactor models with a general fatigue factor and subdomains pertaining to impact, severity, and mental and physical fatigue had relatively good model fits compared to models omitting the subdomains. However, an ESEM model using subscales from the CFS and FSMC fit poorly and did not adequately identify separate factors for mental and physical fatigue. An ESEM model with separate factors for self-reported mental fatigue, depressive symptoms, and cognitive impairment was a good fit. ConclusionsThe working study hypothesis that fatigue constructs would be moderately correlated yet distinct entities was generally supported by the results of the study. However, we found that our hypothesized separation into a latent dimension existed only when the items or subscales came from the same questionnaire, in which case their level of specificity in terms of target, action, context, and time elements for measuring fatigue were consistent. The implications for the principle of compatibility in measuring self-reported MS fatigue are discussed.

Associations Between Midlife Functional Limitations and Self-Reported Health and Cognitive Status: Results from the 1998-2016 Health and Retirement Study.

Life-course approaches to identify and help improve modifiable risk factors, particularly in midlife, may mitigate cognitive aging. We examined how midlife self-rated physical functioning and health may predict cognitive health in older age. We used data from the Health and Retirement Study (1998-2016; unweighted-N = 4,685). We used survey multinomial logistic regression and latent growth curve models to examine how midlife (age 50-64 years) activities of daily living (ADL), physical function, and self-reported health affect cognitive trajectories and cognitive impairment not dementia (CIND) and dementia status 18 years later. Then, we tested for sex and racial/ethnic modifications. After covariates-adjustment, worse instrumental ADL (IADL) functioning, mobility, and self-reported health were associated with both CIND and dementia. Hispanics were more likely to meet criteria for dementia than non-Hispanic Whites given increasing IADL impairment. Midlife health, activities limitations, and difficulties with mobility are predictive of dementia in later life. Hispanics may be more susceptible to dementia in the presence of midlife IADLs. Assessing midlife physical function and general health with brief questionnaires may be useful for predicting cognitive impairment and dementia in later life.

Associations Between Self-Reported Sleep Disturbances and Cognitive Impairment: A Population-Based Cross-Sectional Study

ObjectiveCognitive impairment is a rapidly growing global public health problem in China and worldwide. In the recent decades, emerging studies have explored the associations between sleep disturbances and cognitive impairment. However, the variety of the results imply us that further studies should be conducted for the associations.MethodsThis is a cross-sectional study conducted between August and October 2018 in five cities in Hebei province, China. Subjects were 21,376 community residents. Cognitive impairment was screened by the Chinese version of the Mini-Mental State Examination (MMSE). Scales of Athens Insomnia Scale (AIS), Berlin Questionnaire (BQ), REM (rapid eye movement) Sleep Behavior Disorder Questionnaire (RBDQ-HK), Ullanlinna Narcolepsy Scale (CUNS), and Cambridge-Hopkins Restless Legs Syndrome Questionnaire (CH-RLSq) were used to access insomnia, sleep apnea, REM sleep behavior disorder, narcolepsy, and restless leg syndrome.ResultsThe mean ± SD (standard error) of MMSE, AIS, RBDQ-HK, and CUNS were 27.95 ± 4.79, 2.16 ± 3.39, 5.55 ± 7.75, and 3.76 ± 2.31, respectively. Among the participants, 10.6% and 1.5% of the participants were identified as having a high risk of sleep apnea and restless leg syndrome, respectively. The results of multiple linear regression showed that cognitive impairment was associated with insomnia (β = −0.037, p < 0.001) and narcolepsy (β = −0.023, p < 0.001). The association between sleep apnea (β = −0.002, p > 0.05), REM sleep behavior disorder (β = 0.006, p > 0.05), restless leg syndrome (β = −0.007, p > 0.05), and cognitive impairment were not supported. Other factors associated with cognitive impairment were gender, age, education level, married status, and region.ConclusionThis study provides some epidemiological evidence for the association between sleep disturbances and cognitive impairment among community residents in central China. In this study, the associations between insomnia, narcolepsy, and cognitive impairment were identified, but the associations between sleep apnea, REM sleep behavior disorder, narcolepsy, restless leg syndrome, and cognitive impairment were not supported among community residents.

Trend and effects of high-deductible health insurance plans in the health care system: financial access problems in management of cognitive impairment.

BACKGROUND: High-deductible health plans (HDHPs) are characterized by higher deductibles and lower monthly premiums compared with a typical health plan. HDHPs may reduce, or delay, needed care, which will ultimately lead to poorer access to care for chronically affected participants. OBJECTIVES: To (1) investigate the HDHP enrollment trend and (2) determine the effects of HDHPs on financial access problems for individuals with self-reported cognitive impairment. METHODS: Data between 2010 and 2018 were obtained from the National Health Interview Survey (NHIS). Individuals with cognitive impairment were identified if they were limited by memory difficulties. Problems regarding financial access to health care were assessed based on 6 survey questions from the Centers for Disease Control and Prevention. Multivariable logistic regressions were implemented to evaluate the effects of HDHPs. RESULTS: This study identified 1,148 individuals with cognitive impairment, representing 3.9 million individuals in the United States from 2010 to 2018. A nearly 2-fold increase in HDHP enrollment with cognitive impairment was observed from 2010 (20.9%) to 2018 (41.9%). This increase is similar to that reported for noncognitively impaired individuals. After controlling for possible confounding variables, cognitively impaired individuals with HDPHs were more likely to have overall financial access difficulties compared with those without HDHPs (OR = 1.17, 95% CI = 0.88-1.56, P = 0.271), but this likelihood was not statistically significant. CONCLUSIONS: HDHPs are intended to support effective care options and reduce health care costs. However, our research found that among individuals with cognitive impairment, those with HDHPs experienced some financial access problems, such as affording medical care, follow-up care, and specialists, than those without HDHPs, indicating that HDHPs might have unintended consequences for health care usage. DISCLOSURES: No outside funding supported this study. The authors have no conflicts of interest or financial interests to disclose.

Birth Cohort Differences in Multimorbidity Burden Among Aging U.S. Adults

Multimorbidity is the co-occurrence of two or more chronic health conditions and affects more than half of the US population aged 65 and older. Recent trends suggest increased risk of poor self-reported health, physical disability, cognitive impairment, and mortality among later born birth cohorts, yet we are unaware of work examining cohort trends in multimorbidity among aging US adults. Observations were drawn from the Health and Retirement Study (2000–2018) and included adults aged 51 and older across 7 birth cohorts (1923 and earlier, 1924–1930, 1931–1941, 1942–1947, 1948–1953, 1954–1959, and 1960–1965). Multimorbidity was measured as a count of 9 chronic conditions including heart disease, hypertension, stroke, diabetes, arthritis, lung disease, cancer (excluding skin cancer), depression, and cognitive impairment. General linear models adjusting for repeated measures and covariates including age, sex, race/ethnicity, and education were used to identify whether trends in multimorbidity varied across birth cohort. 31,923 adults contributed 153,940 total observations, grand mean age was 68.0 (SD=10.09), and mean multimorbidity was 2.19 (SD=1.49). In analyses adjusted for age and other covariates, adults born 1948–1953 reported .34 more chronic conditions (SE=.03, p<.001), adults born 1954–1959 reported .42 more chronic conditions (SE=.03, p<.001), and adults born 1960–1965 reported .55 more chronic conditions (SE=.03, p<.001), than those born 1931–1941, respectively. Our preliminary results confirm increasing multimorbidity among later birth cohorts of older Americans and should help guide policy to manage impending health declines among older Americans.

Associations of Post-Acute COVID syndrome with physiological and clinical measures 10 months after hospitalization in patients of the first wave

BackgroundFor a better understanding of the factors underlying the Post-Acute COVID Syndrome, we studied the relationship between symptoms and functional alterations in COVID-19 patients 10 months after hospitalization. MethodsOne-hundred-one patients hospitalized between March 1st and June 30th 2020 participated in a follow-up visit for an assessment of clinical history, comorbidities, lung function, physical capacity and symptoms, including the SGRQ for health-related quality of life, PHQ-9-D for depression, and SOMS-2 J for somatoform disorders. Data were analyzed by univariate comparisons and multiple logistic regression analyses. ResultsMedian age was 60 years, 42% were female, 76% had at least one comorbidity, the median length of the hospital stay was 8 days, 19% had been on the ICU. The most prevalent symptoms included shortness of breath (49%), fatigue (49%) and cognitive impairment (39%). Signs of major depression (PHQ-9-D ≥ 10) occurred in 28%/2% (p < 0.05) of patients with/without self-reported cognitive impairment, with median total SGRQ score being 25.4/5.3 (p < 0.05). There were associations between shortness of breath and BMI, SGRQ and hemoglobin levels; between fatigue, SGRQ and PHQ-9-D; and between cognitive impairment and PHQ-9-D (p < 0.05 each) but not with lung function or physical capacity. Characteristics of the acute disease were not related to symptoms. ConclusionsThe findings demonstrate that 10 months after discharge from a hospital stay due to COVID-19, the percentages of patients with symptoms were high. Symptoms showed a consistent pattern but could not be attributed to altered lung function or physical capacity. Our results suggest a role for alternative etiologies including psychosocial factors.

Age Patterns in Self-Reported Cognitive Impairment Among Older Latino Subgroups and Non-Latino Whites in the United States, 1997-2018: Implications for Public Health Policy.

Background and ObjectivesU.S. Latinos are a heterogeneous population with unique characteristics related to individual-level socioeconomic and contextual factors based on nativity status and country of origin. Population aging and greater public awareness of dementia may contribute to an increasing prevalence of self-reported cognitive impairment. However, population-level trends in self-reported cognitive impairment among Latinos are unclear and it is unknown whether there are differences among Latino subgroups. Thus, this study aims to examine heterogeneity in self-reported cognitive impairment among older U.S. Latino subgroups.Research Design and MethodsWe used data from the 1997–2018 National Health Interview Survey to document age-specific patterns in self-reported cognitive impairment among U.S.-born Mexican, foreign-born Mexican, island-born Puerto Rican, foreign-born Cuban, and U.S.-born non-Latino Whites aged 60 and older. We estimated hierarchical age–period–cohort cross-classified random effects models (HAPC-CCREM) to isolate age patterns in self-reported cognitive impairment across disaggregated Latino subgroups and U.S.-born non-Latino Whites.ResultsThe overall prevalence of self-reported cognitive impairment increased from 6.0% in 1997 to 7.1% in 2018. This increase was evident among U.S.-born non-Latino Whites and U.S.-born and foreign-born Mexicans but not other Latino subgroups. Fully adjusted HAPC-CCREM estimates indicated that Latinos were more likely to self-report cognitive impairment than U.S-born non-Latino Whites (b = 0.371, p < .001). When disaggregated by Latino subgroup, the difference in the likelihood for self-reported cognitive impairment compared to U.S.-born non-Latino Whites was greatest for island-born Puerto Ricans (b = 0.598, p < .001) and smallest for foreign-born Cubans (b = 0.131, p > .05).Discussion and ImplicationsWe found evidence of considerable heterogeneity in the age patterns of self-reported cognitive impairment among U.S. Latino subgroups. We also detected large differences in the likelihood for self-reported cognitive impairment between U.S. Latino subgroups compared to U.S.-born non-Latino Whites. These results underscore the importance of differentiating between unique Latino subpopulations when studying population-level trends in cognitive function.

Self-reported cognitive impairment in cervical cancer survivors: A cross-sectional study.

Cancer-related cognitive impairment (CRCI) is a major obstacle for cervical cancer survivors, preventing the return to their social life. This study assessed the prevalence of CRCI in cervical cancer survivors and studied the association of self-reported cognitive impairment with treatment regimen and the quality of life (QoL) domains depression, anxiety, and fatigue. Six hundred twenty one cervical cancer survivors, treated with combined chemo-radiotherapy (CCRT) (n=458) or surgery only (n=163) were invited in this cross-sectional study. Self-reported cognitive function was assessed using the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog). Fatigue and psychological distress were assessed using EORTC-QLQ C30 and Hospital Anxiety and Depression Scale (HADS). Data of 254 women (40.9%) was available for the analysis. Of those, 204 (80.3%) women had received CCRT and 50 (19.7%) surgery only. In the whole cohort, 42.5% reported significant cognitive impairment. In both treatment groups cognitive complaints were significantly associated with anxiety, depression, and fatigue (all p<0.001). CCRT was strongly associated with increased risk of CRCI (OR=4.02, 95% CI=1.57-10.25). Anxiety, depression, and fatigue increased the risk of CRCI by 13% (OR: 1.13, 95% CI 1.03-1.23), 16% (OR 1.16, 95% CI 1.04-1.28) and 2% (OR 1.02, 95% CI 1.00-1.03), respectively. Almost half of the cervical cancer survivors after CCRT report significant cognitive impairment. CRCI is associated with other indicators of poor QoL, such as depression, anxiety and fatigue. An increased understanding of the specific cognitive domains affected and of the associated late effects like fatigue is crucial to customize successful interventions.

Factors associated with lack of improvement in submaximal exercise capacity of patients with heart failure.

AimsImprovement in exercise capacity is the primary goal of physical activity programmes for patients with heart failure (HF). Although activity programmes are effective for some patients, others do not benefit. Identifying factors related to a lack of improvement in submaximal exercise capacity may help us interpret findings and design new interventions. The aim of this study is to identify factors contributing to a lack of improvement in submaximal exercise capacity 3 months after physical activity advice or an exergame intervention in patients with HF. Additionally, we aimed to assess differences in lack of improvement in submaximal exercise capacity of patients whose baseline exercise capacity predicted a worse compared with better prognosis of HF.Methods and resultsThis secondary analysis of the HF‐Wii study analysed baseline and 3 month data of the 6 min walk test (6MWT) from 480 patients (mean age 67 years, 72% male). Data were analysed separately in patients with a pre‐defined 6 min walking distance at baseline of <300 m (n = 79) and ≥300 m (n = 401). Among patients with a baseline 6MWT of ≥300 m, 18% had deteriorated submaximal exercise capacity. In the multiple logistic regression analysis, lower baseline levels of self‐reported physical activity [odds ratio (OR) = 0.77, 95% confidence interval (CI) = 0.60–0.97], lower baseline levels of cognitive function (OR = 0.87, 95%CI = 0.79–0.96) were significantly associated with lack of improvement in exercise capacity at 3 months. Not randomized to exergaming (OR = 0.63, 95%CI = 0.37–1.09) was likely (P = 0.097) to be associated with lack of improvement in exercise capacity at 3 months. Among the 79 patients with baseline 6MWT of <300 m, 41% (n = 32) did not improve 6MWT distance at 3 months. Independent predictors for the lack of improvement for 6MWT were New York Heart Association class III/IV (OR = 4.68, 95%CI = 1.08–20.35), higher levels of serum creatinine (OR = 1.02, 95%CI = 1.003–1.03), lower cognitive function (OR = 0.86, 95%CI = 0.75–0.99), and fewer anxiety symptoms (OR = 0.84, 95%CI = 0.72–0.98).ConclusionsLower self‐reported physical activity and cognitive impairment predict lack of improvement in submaximal exercise capacity in HF patients. Patients who have a worse prognosis (score <300 m at the 6MWT) are often frail and gain less in exercise capacity. These patients may need a more comprehensive approach to have an effect on exercise capacity, including an individually tailored exercise programme with aerobic exercise (if tolerated) and strength exercises.

Effects of an Oroxylum indicum Extract (Sabroxy®) on Cognitive Function in Adults With Self-reported Mild Cognitive Impairment: A Randomized, Double-Blind, Placebo-Controlled Study.

Background: Oroxylum indicum has been used in traditional Ayurvedic medicine for the prevention and treatment of several diseases and may have neuroprotective effects.Purpose: Examine the effects of Oroxylum indicum on cognitive function in older adults with self-reported cognitive complaints.Study Design: Two-arm, parallel-group, 12-week, randomized, double-blind, placebo-controlled trial.Methods: Eighty-two volunteers received either 500 mg, twice daily of a standardized Oroxylum indicum extract or placebo. Outcome measures included several computer-based cognitive tasks, the Control, Autonomy, Self-Realization, and Pleasure scale (CASP-19), Cognitive Failures Questionnaire (CFQ), and the Montreal Cognitive Assessment (MoCA). Changes in the concentration of brain-derived neurotrophic factor (BDNF) were also examined.Results: Compared to the placebo, Oroxylum indicum was associated with greater improvements in episodic memory, and on several computer-based cognitive tasks such as immediate word recall and numeric working memory, and a faster rate of learning on the location learning task. However, there were no other significant differences in performance on the other assessed cognitive tests, the MoCA total score, or other self-report questionnaires. BDNF concentrations increased significantly in both groups, with no statistically-significant between-group differences. Oroxylum indicum was well tolerated except for an increased tendency for mild digestive complaints and headaches.Conclusion: The results of this first human trial on the cognitive-enhancing effects of Oroxylum indicum suggest that it is a promising herbal candidate for the improvement of cognitive function in older adults with self-reported cognitive complaints.

Follow-up of renal transplant recipients after acute COVID-19-A prospective cohort single-center study.

IntroductionAlthough most patients recover within several weeks after acute COVID‐19, some of them develop long‐lasting clinical symptoms. Renal transplant recipients have an increased mortality risk from COVID‐19. We aimed to describe complications occurring after COVID‐19 in this group of patients.MethodsA prospective single‐center cohort study was conducted at University Hospital Centre Zagreb. Patients with two negative reverse transcriptase‐polymerase chain reaction (RT‐PCR) tests for SARS‐CoV‐2 after COVID‐19 were eligible for further follow‐up at our outpatient clinic. They underwent detailed clinical and laboratory assessments. The primary outcome was the development of complications after COVID‐19.ResultsOnly 11.53% of renal transplant recipients who survived acute COVID‐19 were symptomless and free from new‐onset laboratory abnormalities during the median follow‐up of 64 days (range: 50–76 days). Three patients died from sepsis after discharge from the hospital. In 47 patients (45.2%), clinical complications were present, while 74 patients (71.2%) had one or more laboratory abnormalities. The most common clinical complications included shortness of breath (19.2%), tiredness (11.5%), peripheral neuropathy (7.7%), self‐reported cognitive impairments (5.7%), and dry cough (7.7%). Most common laboratory abnormalities included shortened activated partial thromboplastin time (50%), elevated D‐dimers (36.5%), elevated fibrinogen (30.16%), and hypogammaglobulinemia (24%). Positive RT‐PCR for cytomegalovirus (8.7%), Epstein–Barr virus (26%), or BK virus (16.3%). Multivariate analysis identified the history of diabetes mellitus and eGFR CKD‐EPI as predictors for the development of post‐COVID clinical complications. Six months after acute COVID‐19, elevated D‐dimers persisted with normalization of other laboratory parameters. Twenty‐nine patients were hospitalized, mostly with several concomitant problems. However, initially reported clinical problems gradually improved in the majority of patients.ConclusionPost‐COVID‐19 clinical and laboratory complications are frequent in the renal transplant population, in some of them associated with significant morbidity. All patients recovered from acute COVID‐19 should undergo long‐term monitoring for evaluation and treatment of complications.

A randomised wait-list controlled trial to evaluate Emotional Freedom Techniques for self-reported cancer-related cognitive impairment in cancer survivors (EMOTICON).

BackgroundCancer-related cognitive impairment (CRCI) is a prevalent source of comprised quality of life in cancer survivors. This study evaluated the efficacy of Emotional Freedom Techniques (EFT) on self-reported CRCI (sr-CRCI).MethodsIn this prospective multicentre randomised wait-list controlled study (ClinicalTrials.gov Identifier: NCT02771028), eligible cancer survivors had completed curative treatment, were 18 years or older and screened positive for sr-CRCI with ≥ 43 on the Cognitive Failures Questionnaire (CFQ). Participants were randomised to the immediate treatment group (ITG) or wait-list control (WLC) group, based on age (< or ≥ 65 years), gender, treatment (chemotherapy or not), and centre. The ITG started to apply EFT after inclusion and performed this for 16 weeks. The WLC group could only start the application of EFT after 8 weeks of waiting. Evaluations took place at baseline (T0), 8 weeks (T1) and 16 weeks (T2). The primary outcome was the proportion of patients with sr-CRCI according to the CFQ score.FindingsBetween October 2016 and March 2020, 121 patients were recruited with CFQ ≥ 43 indicating sr-CRCI. At T1, the number of patients scoring positive on the CFQ was significantly reduced in the ITG compared to the WLC group (40.8% vs. 87.3% respectively; p<0.01). For the WLC group, a reduction in CFQ scores was observed at T2, comparable to the effect of the ITG at T1. Linear mixed model analyses indicated a statistically significant reduction in the CFQ score, distress, depressive symptoms, fatigue and also an improvement in quality of life.InterpretationThis study provides evidence for the application of EFT for sr-CRCI in cancer survivors and suggests that EFT may be useful for other symptoms in cancer survivors.

Characterization of cognitive function in survivors of diffuse gliomas using resting-state functional MRI (rs-fMRI)

As treatments for diffuse gliomas have advanced, survival for patients with gliomas has also increased. However, there remains limited knowledge on the relationships between brain connectivity and the lasting changes to cognitive function that glioma survivors often experience long after completing treatment. This resting-state functional magnetic resonance imaging (rs-fMRI) study explored functional connectivity (FC) alterations associated with cognitive function in survivors of gliomas. In this pilot study, 22 patients (mean age 43.8 ± 11.9) with diffuse gliomas who completed treatment within the past 10 years were evaluated using rs-fMRI and neuropsychological measures. Novel rs-fMRI analysis methods were used to account for missing brain in the resection cavity. FC relationships were assessed between cognitively impaired and non-impaired glioma patients, along with self-reported cognitive impairment, non-work daily functioning, and time with surgery. In the cognitively non-impaired patients, FC was stronger in the medial prefrontal cortex, rostral prefrontal cortex, and intraparietal sulcus compared to the impaired survivors. When examining non-work daily functioning, a positive correlation with FC was observed between the accumbens and the intracalcarine cortices, while a negative correlation with FC was observed between the parietal operculum cortex and the cerebellum. Additionally, worse self-reported cognitive impairment and worse non-work daily functioning were associated with increased FC between regions involved in cognition and sensorimotor processing. These preliminary findings suggest that neural correlates for cognitive and daily functioning in glioma patients can be revealed using rs-fMRI. Resting-state network alterations may serve as a biomarker for patients’ cognition and functioning.

Chemotherapy-related subjective cognitive impairment in breast cancer patients in semi-rural South Africa

BackgroundBreast cancer is the most commonly diagnosed cancer amongst women worldwide. Whilst current evidence indicates the therapeutic benefits from the use of chemotherapy, self-perceived cognitive difficulties emerged as a frequent occurrence during and after chemotherapy treatment in breast cancer patients.AimThe current study sought to investigate self-perceived cognitive impairment in a group of breast cancer patients in semi-rural South Africa.SettingThe patients were recruited from an outpatient oncology clinic at a semi-rural, tertiary academic hospital in Gauteng, South Africa.MethodsIn a randomised, quantitative, time-based series study, 30 female patients aged 21–60 years (mean age = 50 years) diagnosed with stages II and III breast cancer on CMF (cyclophosphamide, methotrexate, fluorouracil) (n = 10) and FAC (fluorouracil, adriamycin, cyclophosphamide) (n = 20) chemotherapy regimens, completed the self-reported Functional Assessment of Cancer Therapy-Cognition (Fact-Cog) test as a measure of subjective cognitive functioning at three points during the course of treatment (T0, T1, T2).ResultsThe results of the paired sample t-tests showed the scores on the Fact-Cog test confirmed significant cognitive decline for both treatment groups from baseline (T0) to completion (T2) of chemotherapy; CMF group, t (9) = 2.91, p = 0.017 and the FAC group t (19) = 4.66, p < 0.001.ConclusionThis study confirms that self-reported subjective cognitive impairment is common in breast cancer patients who received chemotherapy in a sample of South African patients. The results have implications for the overall care of cancer patients.ContributionThe context-based knowledge engendered by the current study is expected to augment the continuum of care for breast cancer patients.
