ABSTRACT

PURPOSE: Cancer-related cognitive impairment (CRCI) is under-addressed by healthcare professionals owing to a lack of clinical management guidelines. This European Delphi study proposes recommendations to healthcare professionals for the management of CRCI in patients with non-central nervous system (non-CNS) cancers. METHODS: Twenty-two recommendations were developed based on a literature review and authors' clinical experience, split into three categories: screening, cognitive assessment, intervention. The survey included European professionals, experts in CRCI. The Delphi method was used: experts rated the clinical relevancy of recommendations on a 9-point Likert scale in three rounds. A recommendation was accepted if all votes were between 7 and 9. Recommendations not accepted in round 1 and round 2 were deleted, or modified and rated in round 3. RESULTS: Eighteen professionals (psychologists, physicians, researchers) voted and accepted 15 recommendations. Experts recommended the systematic screening of CRCI, followed by a short objective cognitive assessment, if complaints screened. A comprehensive evaluation is recommended if CRCI persists 6 months post-treatment. Cognitive rehabilitation, physical activity, meditative-movement therapy, and multimodal intervention should be offered. Recommendations about frequency and duration of interventions, the professional to administer cognitive rehabilitation and the use of meditation and cognitive training without psychoeducation were not accepted. CONCLUSIONS: This survey provides 15 recommendations to assist healthcare professionals in detecting, assessing and offering interventions for CRCI. IMPLICATIONS FOR CANCER SURVIVORS: These recommendations should be included in supportive care to help healthcare professionals to detect CRCI and propose the best available intervention for patients with cognitive complaints. Developing CRCI management in clinical settings would improve patients' quality of life.

ABSTRACT

BACKGROUND: Behçet's disease (BD) is a rare form of vasculitis involving both veins and arteries of all calibers. Psychological symptoms and cognitive impairment appear to be frequent, but few data are available. METHODS: All consecutive patients in our center fulfilling the 2013 BD criteria underwent a psychometric evaluation with auto- (SCL-90-R and Modified Fatigue Index) and hetero-questionnaires (MINI). A standardized test battery assessed cognitive dysfunction. Data were correlated with BD activity as well as quality of life (SF-36). RESULTS: We included 20 consecutive patients (16 men, four women) with a median [IQR] age of 38 (30.0-45.5) and a median disease duration of 7 years (1.8-11.0). Five patients had an abnormal brain MRI. The SCL-90-R questionnaire highlighted eight psychopathological profiles (42.1%) that correlated with altered quality of life and more severe fatigue. The most frequent symptoms were anxiety (9/19, 47.4%), somatization (8/19, 42.1%) and phobia (5/19, 26.3%). Psychopathological symptoms appeared to be more severe, but not more frequent, in neuro-Behçet's patients. Based on standardized cognitive evaluation, nine patients had cognitive impairment defined by three or more altered tests. Notably, 6/9 patients did not have any complaint of memory loss and were thus considered ansognostic. CONCLUSION: Cognitive involvement was significantly associated with BD activity score (BSAS) but not with brain MRI abnormalities.

ABSTRACT

BACKGROUND: Using the large nationwide French, national, multicenter, prospective cancer and toxicities (CANTO) cohort, we assessed cognitive functioning change after cancer treatments in a subgroup of breast cancer (BC) patients. METHODS: We included patients with newly diagnosed invasive stage I-III BC enrolled in the CANTO substudy focused on cognitive evaluation and healthy control women matched for age and education. Episodic and working memory, executive functions, processing speed, attention, self-report cognitive difficulties (SRCD), fatigue, anxiety and depression were assessed with neuropsychological tests and self-report questionnaires before treatment (baseline) and approximately 1 (year 1) and 2 years (year 2) after diagnosis. We used linear mixed models to study changes in cognition and tested the effect of adjuvant chemotherapy. RESULTS: We studied 276 localized BC patients (62% chemotherapy) compared with 135 healthy controls (HC). After adjustment, patients had lower baseline working memory, processing speed, and attention scores than HC (P ≤ .001), and the difference remained statistically significant over follow-up for working memory and processing speed. Executive function scores were similar between groups at baseline but decreased at year 1 among patients compared with HC (Pchange = .006). This decrease in chemotherapy patients was statistically significant compared with HC scores (Pchange < .001). After adjustment, SRCD were similar between BC patients and HC at baseline but increased in patients after treatment at year 1 (Pchange = .002). CONCLUSIONS: Cognitive difficulties are an important concern in BC patients, starting at diagnosis. Cancer treatments induce executive function decline and SRCD, which decrease over follow-up.

ABSTRACT

OBJECTIVES: Long COVID is a major public health issue. Whether long COVID is comorbid with psychiatric disorders remains unclear. Here, we investigate the association between long COVID, psychiatric symptoms and psychiatric disorders. DESIGN: Cross-sectional. SETTINGS: Bicêtre Hospital, France, secondary care. PARTICIPANTS: One hundred seventy-seven patients admitted in intensive care unit during acute phase and/or reporting long COVID complaints were assessed 4 months after hospitalisation for an acute COVID. MAIN OUTCOME MEASURES: Eight long COVID complaints were investigated: fatigue, respiratory and cognitive complaints, muscle weakness, pain, headache, paraesthesia and anosmia. The number of complaints, the presence/absence of each COVID-19 complaint as well as lung CT scan abnormalities and objective cognitive impairment) were considered. Self-reported psychiatric symptoms were assessed with questionnaires. Experienced psychiatrists assessed Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition-based diagnoses of psychiatric disorders. RESULTS: One hundred and fifteen (65%) patients had at least one long COVID complaint. The number of long COVID complaints was associated with psychiatric symptoms. The number of long COVID complaints was higher in patients with psychiatric disorders (mean (m) (SD)=2.47 (1.30), p<0.05), new-onset psychiatric disorders (m (SD)=2.41 (1.32), p<0.05) and significant suicide risk (m (SD)=2.67 (1.32), p<0.05) than in patients without any psychiatric disorder (m (SD)=1.43 (1.48)). Respiratory complaints were associated with a higher risk of psychiatric disorder and new-onset psychiatric disorder, and cognitive complaints were associated with a higher risk of psychiatric disorder. CONCLUSIONS: Long COVID is associated with psychiatric disorders, new-onset psychiatric disorders and suicide risk. Psychiatric disorders and suicide risk should be systematically assessed in patients with long COVID.

ABSTRACT

Importance: Little is known about long-term sequelae of COVID-19. Objective: To describe the consequences at 4 months in patients hospitalized for COVID-19. Design, Setting, and Participants: In a prospective uncontrolled cohort study, survivors of COVID-19 who had been hospitalized in a university hospital in France between March 1 and May 29, 2020, underwent a telephone assessment 4 months after discharge, between July 15 and September 18, 2020. Patients with relevant symptoms and all patients hospitalized in an intensive care unit (ICU) were invited for further assessment at an ambulatory care visit. Exposures: Survival of hospitalization for COVID-19. Main Outcomes and Measures: Respiratory, cognitive, and functional symptoms were assessed by telephone with the Q3PC cognitive screening questionnaire and a checklist of symptoms. At the ambulatory care visit, patients underwent pulmonary function tests, lung computed tomographic scan, psychometric and cognitive tests (including the 36-Item Short-Form Health Survey and 20-item Multidimensional Fatigue Inventory), and, for patients who had been hospitalized in the ICU or reported ongoing symptoms, echocardiography. Results: Among 834 eligible patients, 478 were evaluated by telephone (mean age, 61 years [SD, 16 years]; 201 men, 277 women). During the telephone interview, 244 patients (51%) declared at least 1 symptom that did not exist before COVID-19: fatigue in 31%, cognitive symptoms in 21%, and new-onset dyspnea in 16%. There was further evaluation in 177 patients (37%), including 97 of 142 former ICU patients. The median 20-item Multidimensional Fatigue Inventory score (n = 130) was 4.5 (interquartile range, 3.0-5.0) for reduced motivation and 3.7 (interquartile range, 3.0-4.5) for mental fatigue (possible range, 1 [best] to 5 [worst]). The median 36-Item Short-Form Health Survey score (n = 145) was 25 (interquartile range, 25.0-75.0) for the subscale "role limited owing to physical problems" (possible range, 0 [best] to 100 [worst]). Computed tomographic lung-scan abnormalities were found in 108 of 171 patients (63%), mainly subtle ground-glass opacities. Fibrotic lesions were observed in 33 of 171 patients (19%), involving less than 25% of parenchyma in all but 1 patient. Fibrotic lesions were observed in 19 of 49 survivors (39%) with acute respiratory distress syndrome. Among 94 former ICU patients, anxiety, depression, and posttraumatic symptoms were observed in 23%, 18%, and 7%, respectively. The left ventricular ejection fraction was less than 50% in 8 of 83 ICU patients (10%). New-onset chronic kidney disease was observed in 2 ICU patients. Serology was positive in 172 of 177 outpatients (97%). Conclusions and Relevance: Four months after hospitalization for COVID-19, a cohort of patients frequently reported symptoms not previously present, and lung-scan abnormalities were common among those who were tested. These findings are limited by the absence of a control group and of pre-COVID assessments in this cohort. Further research is needed to understand longer-term outcomes and whether these findings reflect associations with the disease.

ABSTRACT

OBJECTIVE: Cognitive complaints are more frequent in women with breast cancer (BC) than in healthy controls and can be present before any treatment. Findings regarding contributive factors remain inconsistent. This study aimed to identify different groups of patients with cognitive complaints at BC diagnosis and to determine whether these different groups were associated with demographic, medical, or psychological characteristics. METHODS: Cognitive complaints were assessed in a subset of 264 women from the French multicenter prospective CANTO cohort, at baseline before any treatment. Clustering analyzes were performed using the six-cognitive dimension Costa's scoring of the FACT-Cog V3. Univariable analyses were used to study how cognitive function (standardized neuropsychological tests, ICCTF), anxiety, depression, fatigue, and quality of life (HADS, FA12, QLQ-C30) were associated with specific cognitive complaints groups. RESULTS: Results included 263 women (54±11 years), newly diagnosed with BC (69% stages I-III). Four distinct groups emerged, ranged from "no complaints" (22.8%), "low complaints" (55.1), "mixed complaints" (14.5%), to "consistent complaints" (7.6%). No significant differences were found in terms of demographic and medical factors between the four groups. However, the groups with higher proportions of patients with complaints were found to have more impairment in executive function, higher scores of anxiety, depressive symptoms, and fatigue, and lower quality of life, than the groups with lower proportions of cognitive complaints. CONCLUSION: Using complete cognitive assessment prior to BC treatment, we identified four distinct cognitive complaints groups with specific characteristics. This work provides valuable clinical basis to further investigations for a better understanding of cognitive complaints and their associates.

ABSTRACT

BACKGROUND: There is no treatment for cancer-related cognitive impairment, an important adverse effect that negatively impacts quality of life (QOL). We conducted a 3-arm randomized controlled trial to evaluate the impact of computer-assisted cognitive rehabilitation (CR) on cognition, QOL, anxiety, and depression among cancer patients treated with chemotherapy. METHODS: Patients who reported cognitive complaints during or after completing chemotherapy were randomly assigned to 1 of 3 12-week CR programs: computer-assisted CR with a neuropsychologist (experimental group A), home cognitive self-exercises (active control group B), or phone follow-up (active control group C). Subjective cognition was assessed by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), objective cognition was assessed by neuropsychological tests, QOL was assessed by the FACT-General, and depression and anxiety were assessed by psychological tests. The primary endpoint was the proportion of patients with a 7-point improvement in the FACT-Cog perceived cognitive impairment (PCI) score. RESULTS: Among the 167 enrolled patients (median age, 51 years), group A had the highest proportion of patients with a 7-point PCI improvement (75%), followed by groups B (59%) and C (57%), but the difference was not statistically significant (P = .13). Compared with groups B and C, the mean difference in PCI score was significantly higher in group A (P = .02), with better perceived cognitive abilities (P < .01) and a significant improvement in working memory (P = .03). Group A reported higher QOL related to cognition (FACT-Cog QOL) (P = .01) and improvement in depression symptoms (P = .03). CONCLUSIONS: These results suggest a benefit of a computer-based CR program in the management of cancer-related cognitive impairment and complaints.

ABSTRACT

BACKGROUND: Twenty to 30% of patients with breast cancer have cognitive impairment after surgery and before adjuvant treatment, but very few studies have focused on cognition before any treatment. This study used a subgroup of women with newly diagnosed breast cancer from the French cancer and toxicities (CANTO) cohort to describe cognition before any treatment in comparison with a group of healthy controls (HC). METHODS: Cognitive assessment was performed before any breast cancer treatment (surgery or neoadjuvant treatment) on women with newly diagnosed invasive stage I-III breast cancer and HCs. Objective cognitive performance, cognitive complaints, anxiety, depression, and fatigue were assessed. Objective cognitive impairment was defined according to International Cognition and Cancer Task Force recommendations. RESULTS: Of the 264 included patients with breast cancer (54 ± 11 years) and 132 age-matched HCs (53 ± 9 years), overall objective cognitive impairment was observed in 28% of patients with breast cancer and 8% of HCs (P < 0.001). Cognitive complaints were reported by 24% of patients versus 12% of HCs (P < 0.01). Patients reported significantly more anxiety and emotional and cognitive fatigue than HCs (P < 0.01). After adjustment, significantly more patients with breast cancer had overall objective cognitive impairment than HCs [OR = 3.01; 95% confidence interval (CI): 1.31-6.88] without significant difference between groups for cognitive complaints (OR = 1.38; 95% CI: 0.65-2.92). Cognitive complaints were positively associated with fatigue (OR = 1.03; 95% CI: 1.02-1.05). CONCLUSIONS: In this prospective study, compared with HCs, patients with localized breast cancer had more objective cognitive impairment before any treatment. Cognitive complaints were mostly related to fatigue. IMPACT: Baseline assessment before treatment is important to assess the impact of each cancer treatment on cognition.

ABSTRACT

A number of neurotoxicity associated with oncological treatments has been reported in non-central nervous system cancers. An expert group presents the state of the art and a guide to help the choice of appropriated tools to assess patient cognition in studies on oncology and neurobehavior in animal models. In addition, current cognitive rehabilitation programs currently under evaluation are also discussed. Cognitive assessments in oncology depend on the research question, study design, cognitive domains, patients' characteristics, psychometric properties of the tests, and whether the tests are supervised or not by a neuropsychologist. Batteries of electronic tests can be proposed, but several of them are characterized by weak psychometric developments. In order to improve the comprehension on the impact of cancer treatments on cognition, new animal models are in development, and would in the future include non-human primate models. By bringing together the skills and practices of oncologists, neurologists, neuropsychologists, neuroscientists, we propose a series of specific tools and tests that accompany the cognitive management of non-CNS cancer patients.

ABSTRACT

OBJECTIVE: Cognitive investigations in brain tumor patients have mostly explored episodic memory without differentiating between encoding, storage, and retrieval deficits. The aim of this study is to offer insight into the memory sub-processes affected in primary brain tumor patients and propose an appropriate assessment method. METHOD: We retrospectively reviewed the clinical and memory assessments of 158 patients with primary brain tumors who had presented to our departments with cognitive complaints and were investigated using the Free and Cued Selective Reminding Test. RESULTS: Retrieval was the process of episodic memory most frequently affected, with deficits in this domain detected in 92% of patients with episodic memory impairments. Storage and encoding deficits were less prevalent, with impairments, respectively, detected in 41% and 23% of memory-impaired patients. The pattern of episodic memory impairment was similar across different tumor histologies and treatment modalities. CONCLUSION: Although all processes of episodic memory were found to be impaired, retrieval was by far the most widely affected function. A thorough assessment of all three components of episodic memory should be part of the regular neuropsychological evaluation in patients with primary brain tumors.

ABSTRACT

BACKGROUND: New generation hormone-therapies (NGHT) targeting the androgen signalling pathway are nowadays proposed to elderly patients with metastatic castration-resistant prostate cancer (CRPCa). The impact of these treatments on cognitive function has never been evaluated whereas cognitive impairment may have an impact on the autonomy and the treatment adherence. The aim of this study is to prospectively assess the incidence of cognitive impairment in elderly men after treatment by NGHT for a metastatic CRPCa. METHODS/DESIGN: The Cog-Pro study is a multicentre longitudinal study including CRPCa patients ≥70 years old treated with NGHT (n = 134), control metastatic prostate cancer patients without castration resistance treated with first generation androgen deprivation therapy (n = 55), and healthy participants (n = 33), matched on age and education. Cognitive, geriatric and quality of life assessment and biological tests will be performed at baseline, 3, 6 and 12 months after start of the treatment (inclusion time). The primary endpoint is the proportion of elderly patients receiving a NGHT who will experience a decline in cognitive performances within 3 months after study enrollment. Secondary endpoints concern: autonomy, quality of life, anxiety, depression, cognitive reserve, adherence to hormone-therapy, comparison of the cognitive impact of 2 different NGHT (abiraterone acetate and enzalutamide), impact of co-morbidities and biological assessments. DISCUSSION: Evaluating, understanding and analyzing the incidence, severity of cognitive impairments and their impact on quality of life, autonomy and adherence in this group of patients with advanced disease is a challenge. This study should help to improve cancer care of elderly patients and secure the use of oral treatments as the risk of non-observance does exist. Our results will provide up-to date information for patients and caregivers on impact of these treatments on cognitive function in order to help the physicians in the choice of the treatment. TRIAL REGISTRATION: NCT02907372 , registered: July 26, 2016.

ABSTRACT

PURPOSE OF REVIEW: Survival of brain tumor patients has increased with improvements in cancer treatments. However, treatments like radiotherapy can be neurotoxic and thus new end-points in clinical trials, as well as in individual management, have appeared. This article reviews the cognitive outcomes after radiotherapy in brain tumor patients, focusing on radiation-induced impairments, and then discusses actual cognitive assessment limitations. RECENT FINDINGS: Although physiopathology of radiation-induced cognitive impairments remains elusive, a general course can be described as acute, early-delayed, and late-delayed effects corresponding to different processes. The last is of high interest because the related impairments are irreversible. In this context, a cognitive assessment should be performed as often as possible, but actual tools are unfortunately not developed. Nevertheless, with respect to neuro-oncologic specificities, new cognitive tools could be developed to overcome these limitations. SUMMARY: Improvements in neuropsychologic assessment for brain tumor patients are urgently needed. A dynamic vision of radiation-induced cognitive impairments appears inevitable and should lead to a change in actual considerations about neurotoxicity follow-up.

ABSTRACT

Several DNA cis-elements and trans-acting factors were described to be involved in transcription termination and to release the elongating RNA polymerases from their templates. Different models for the molecular mechanism of transcription termination have been suggested for eukaryotic RNA polymerase I (Pol I) from results of in vitro and in vivo experiments. To analyse the molecular requirements for yeast RNA Pol I termination, an in vivo approach was used in which efficient termination resulted in growth inhibition. This led to the identification of a Myb-like protein, Ydr026c, as bona fide termination factor, now designated Nsi1 (NTS1 silencing protein 1), since it was very recently described as silencing factor of ribosomal DNA. Possible Nsi1 functions in regard to the mechanism of transcription termination are discussed.

ABSTRACT

Psychologist-nurse, a rewarding collaboration. The collaboration between nurses and psychologists is relatively recent within healthcare institutes. Gaining maximum value from such a collaboration requires solid knowledge of the roles and the limits of each profession as well as a real desire to work together, for the benefit of the greater well-being of the patient and, indirectly, of the teams.

ABSTRACT

OBJECTIVE: To evaluate the performance of a French version of the modified Telephone Interview for Cognitive Status (F-TICS-m) in identifying cognitive decline among elderly women. METHODS: All women aged 72-86 participating in the 'Etude Epidémiologique auprès de Femmes de l'Education Nationale' (E3N) cohort and living in or near Paris constituted the target population of the validation study. Volunteer women (n = 120) underwent both a 20-min telephone interview and a face-to-face neuropsychological examination at an interval of few days (median interval: 10 days). The telephone interview included F-TICS-m, as well as a recall of key elements of a short story, arithmetic/verbal problems and two verbal fluency tests. Neuropsychological examination consisted of a standardized battery of cognitive tests (including the Mini-Mental State Examination (MMSE), the Free and Cued Selective Reminding Test-FCSRT, Trailmaking tests A and B, the similarities subtest of the Wechsler Adult Intelligence Scale-III, etc.) the Instrumental Activities of Daily Living questionnaire, and the Geriatric Depression Scale. Neuropsychological examination led to classification of each subject as cognitively normal (n = 92) or impaired/demented (n = 28). RESULTS: F-TICS-m showed satisfactory internal consistency (Cronbach's alpha = 0.69). It correlated linearly with MMSE (Pearson's r = 0.72). Concurrent validity against the gold-standard classification was satisfactory, with an area under the ROC curve (AUC) of 0.83. The combination of F-TICS-m and the other telephone tests had no additional effect on discrimination power in our sample (AUC = 0.81). CONCLUSION: F-TICS-m is a valid instrument for assessing the overall cognitive status of French elderly women. Its validity in men and its reproducibility warrant further studies.

ABSTRACT

The Rho small GTPases are crucial proteins involved in regulation of signal transduction cascades from extracellular stimuli to cell nucleus and cytoskeleton. It has been reported that these GTPases are directly associated with cardiovascular disorders. In this context, we have searched for novel modulators of Rho GTPases, and here we describe p63RhoGEF a new Db1-like guanine nucleotide exchange factor (GEF). P63RhoGEF encodes a 63 kDa protein containing a Db1 homology domain in tandem with a pleckstrin homology domain and is most closely related to the second Rho GEF domain of Trio. Northern blot and in situ analysis have shown that p63RhoGEF is mainly expressed in heart and brain. In vitro guanine nucleotide exchange assays have shown that p63RhoGEF specifically acts on RhoA. Accordingly, p63RhoGEF expression induces RhoA-dependent stress fiber formation in fibroblasts and in H9C2 cardiac myoblasts. Moreover, we show that p63RhoGEF activation of RhoA in intact cells is dependent on the presence of the PH domain. Using a specific anti-p63RhoGEF antibody, we have detected the p63RhoGEF protein by immunocytochemistry in human heart and brain tissue sections. Confocal microscopy shows that p63RhoGEF is located in the sarcomeric I-band mainly constituted of cardiac sarcomeric actin. Together, these results show that p63RhoGEF is a RhoA-specific GEF that may play a key role in actin cytoskeleton reorganization in different tissues, especially in heart cellular morphology.
