This meta-analysis aimed to (i) examine demographic, disease-related, and treatment-related risk factors, (ii) estimate the prevalence, and (iii) describe the course of severe fatigue following ...breast cancer (BC) treatment.
PubMed, PsycINFO, Cochrane, CINAHL, and Web of Science were systematically searched from inception up to 23 November 2015. Risk factors and prevalence rates were analyzed with inverse variance random-effects analyses. Heterogeneity was studied with sensitivity analyses.
Twenty-seven studies were included (N = 12 327). Breast cancer survivors (BCS) with a partner were at lower risk for severe fatigue than survivors without a partner risk ratio (RR) 0.96, 95% confidence interval (CI) 0.93–0.98. Survivors with stage II or III cancer, and survivors treated with chemotherapy were at higher risk for severe fatigue than survivors with stage 0 or I cancer and without chemotherapy (RR respectively 1.18, 95% CI 1.08–1.28; 1.12, 95% CI 1.06–1.19). Survivors treated with surgery, radiotherapy, and chemotherapy, and survivors with this combination plus hormone therapy were at higher risk than survivors with other treatment combinations (RR respectively 1.18, 95% CI 1.05–1.33; 1.38, 95% CI 1.15–1.66). Survivors treated with surgery and surgery plus radiotherapy were at lower risk than survivors with additional treatments (RR respectively 0.83, 95% CI 0.70–0.98; 0.87, 95% CI 0.78–0.96). Hormone and targeted therapy were no significant risk factors. The pooled prevalence of severe fatigue was 26.9% (95% CI 23.2–31.0), but this should be interpreted with caution because of high heterogeneity. A relatively large decrease in the prevalence of severe fatigue seemed to occur in the first half year after treatment completion.
Approximately one in four BCS suffer from severe fatigue. Risk factors of severe fatigue were higher disease stages, chemotherapy and receiving the combination of surgery, radiotherapy, and chemotherapy, both with and without hormone therapy. Having a partner, receiving only surgery, and surgery plus radiotherapy decreased the risk.
Severe fatigue occurs in one in four breast cancer survivors (BCS). Quality of life (QOL) and psychological factors are important in fatigue-oriented interventions for BCS, but an up-to-date overview ...is lacking. The aims of this review were to (i) provide a comprehensive overview of the relationship of fatigue with QOL and factors that can be addressed in psychological interventions for fatigue in BCS and (ii) determine the strength of evidence for these relationships. A systematic literature search was conducted to find studies on fatigue in BCS who had completed curative breast cancer treatment. Fatigue-related factors of 57 eligible studies were extracted and the level of evidence was determined. Factors regarding QOL (ie, general QOL, functioning, work ability, and mental health) had a negative relationship with fatigue (moderate to strong evidence). Target factors for psychological interventions were divided into the subcategories emotional problems, sleep disturbances, physical activity, pain, coping with cancer, dysfunctional cognitions, and social support. Moderate to strong evidence appeared for a relationship of fatigue with depressive symptoms, anxiety, distress, sleep disturbances, lower physical activity levels, pain, difficulties with coping with cancer, and catastrophizing about symptoms. These factors are points of attention for existing and future psychological interventions for fatigue in BCS.
•Fatigue in breast cancer survivors is related to a lower quality of life•Fatigue has a negative relationship with functioning, work ability and pain•Strong evidence exists for a relationship of fatigue with psychological factors•Most evidence appears for sleep, emotions, coping, activity and catastrophizing•The identified factors should be addressed in interventions for fatigue
Kidney transplant recipients (KTRs) elicit an impaired immune response after COVID-19 vaccination; however, the exact clinical impact remains unclear. We therefore analyse the relationship between ...antibody levels after vaccination and the risk of COVID-19 in a large cohort of KTRs. All KTRs living in the Netherlands were invited to send a blood sample 28 days after their second COVID-19 vaccination for measurement of their IgG antibodies against the receptor-binding domain of the SARS-CoV-2 spike protein (anti-RBD IgG). Information on COVID-19 was collected from the moment the blood sample was obtained until 6 months thereafter. Multivariable Cox and logistic regression analyses were performed to analyse which factors affected the occurrence and severity (i.e., hospitalization and/or death) of COVID-19. In total, 12,159 KTRs were approached, of whom 2885 were included in the analyses. Among those, 1578 (54.7%) became seropositive (i.e., anti-RBD IgG level >50 BAU/mL). Seropositivity was associated with a lower risk for COVID-19, also after adjusting for multiple confounders, including socio-economic status and adherence to COVID-19 restrictions (HR 0.37 (0.19-0.47),
= 0.005). When studied on a continuous scale, we observed a log-linear relationship between antibody level and the risk for COVID-19 (HR 0.52 (0.31-0.89),
= 0.02). Similar results were found for COVID-19 severity. In conclusion, antibody level after COVID-19 vaccination is associated in a log-linear manner with the occurrence and severity of COVID-19 in KTRs. This implies that if future vaccinations are indicated, the aim should be to reach for as high an antibody level as possible and not only seropositivity to protect this vulnerable patient group from disease.
About one third of breast cancer survivors suffer from persistent severe fatigue after completion of curative cancer treatment. Face-to-face cognitive behavioral therapy (F2F CBT), especially ...designed for fatigue in cancer survivors, was found effective in reducing fatigue. However, this intervention is intensive and treatment capacity is limited. To extend treatment options, a web-based version of CBT requiring less therapist time was developed. This intervention is aimed at changing fatigue-perpetuating cognitions and behaviors. The efficacy of web-based CBT will be examined in a multicenter randomized controlled trial.
In total, 132 severely fatigued breast cancer survivors will be recruited and randomized to either an intervention condition or care as usual (ratio 1:1). Participants will be assessed at baseline and 6 months thereafter. The intervention group will receive web-based CBT, consisting of three F2F sessions and maximally eight web-based modules over a period of 6 months. The care as usual group will be on a waiting list for regular F2F CBT. The total duration of the waiting list is 6 months. The primary outcome of the study is fatigue severity. Secondary outcomes are functional impairments, psychological distress and quality of life.
If web-based CBT is effective, it will provide an additional treatment option for fatigue in breast cancer survivors. Web-based CBT is expected to be less time-consuming for therapists than regular F2F CBT, which would result in an increased treatment capacity. Moreover, the intervention would become more easily accessible for a larger number of patients, and patients can save travel time and costs.
Dutch Trial Registry--NTR4309.
This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects.
Overall effects and ...intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs.
CST had a statistically significant but small effect on depression (g = −0.31,95% confidence interval (CI) = −0.40;-0.22) and anxiety (g = −0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (β = −0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (β = −0.16,95%CI = -0.25;-0.07) and anxiety (β = −0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05).
CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.
•The average effect of CST on symptoms of anxiety and depression in cancer patients are statistically significant but small•Younger patients and patients who received chemotherapy benefit more from CST•CST effects are larger when delivered face-to-face, led by a psychologist and targeted to patients with psychological distress
Little is known about the functional course after initiating dialysis in elderly patients with ESKD. The aim of this study was to assess the association of the initiation of dialysis in an elderly ...population with functional status and caregiver burden.
This study included participants aged ≥65 years with ESKD who were enrolled in the Geriatric Assessment in Older Patients Starting Dialysis study. All underwent a geriatric assessment and a frailty screening (Fried Frailty Index and Groningen Frailty Indicator) at dialysis initiation. Functional status (activities of daily life and instrumental activities of daily life) and caregiver burden were assessed at baseline and after 6 months. Decline was defined as loss of one or more domains in functional status, stable as no difference between baseline and follow-up, and improvement as gain of one or more domains in functional status. Logistic regression was performed to assess the association between the combined outcome functional decline/death and potential risk factors.
Of the 196 included participants functional data were available for 187 participants. Mean age was 75±7 years and 33% were women. At the start of dialysis, 79% were care dependent in functional status. After 6 months, 40% experienced a decline in functional status, 34% remained stable, 18% improved, and 8% died. The prevalence of high caregiver burden increased from 23%-38% (
=0.004). In the multivariable analysis age (odds ratio, 1.05; 95% confidence interval, 1.00 to 1.10 per year older at baseline) and a high Groningen Frailty Indicator compared with low score (odds ratio, 1.97; 95% confidence interval, 1.05 to 3.68) were associated with functional decline/death.
In patients aged ≥65 years, functional decline within the first 6 months after initiating dialysis is highly prevalent. The risk is higher in older and frail patients. Loss in functional status was mainly driven by decline in instrumental activities of daily life. Moreover, initiation of dialysis is accompanied by an increase in caregiver burden.
Background: Fatigue is one of the most common and distressing long-term effects of cancer treatment. Cognitive behavioral therapy (CBT) is an evidence-based intervention for patients with severe ...post-cancer fatigue. CBT for fatigue is a complex intervention consisting of multiple elements like a graded activity program, regulation of the sleep-wake rhythm and reformulation of fatigue-related cognitions. The contribution of the separate elements to the positive effect of CBT on fatigue is unclear. The main objective of this pragmatic crossover trial was comparing the efficacy of graded activity with the other elements of CBT in reducing post-cancer fatigue.
Material and methods: Severely fatigued cancer survivors were randomized to (i) graded activity followed by the other elements of CBT after crossover (n = 41), or (ii) the two components in reverse order (n = 48). Fatigue severity was measured at baseline, before crossover and after CBT (Checklist Individual Strength (CIS), Fatigue Severity subscale). Differences in effects on fatigue were examined with a linear regression analysis. Objective physical activity, perceived activity and self-efficacy were explored as mediators of the effect of graded activity.
Results: Before crossover, the reduction in fatigue was significantly larger after graded activity than after the other elements (β = 4.75, 95% confidence interval (95% CI) = −9.19; −0.32). An increase in perceived activity mediated this effect (β = −4.17, 95% CI = −7.37; −1.37).
Conclusions: Graded activity is an important component of CBT for post-cancer fatigue as it resulted in a larger reduction in fatigue compared with the other elements, mediated by an increased level of perceived activity. Results indicated that the other elements of CBT are of added value in reducing fatigue.
Objective
Psychosocial interventions can reduce cancer‐related fatigue effectively. However, it is still unclear if intervention effects differ across subgroups of patients. These meta‐analyses aimed ...at evaluating moderator effects of (a) sociodemographic characteristics, (b) clinical characteristics, (c) baseline levels of fatigue and other symptoms, and (d) intervention‐related characteristics on the effect of psychosocial interventions on cancer‐related fatigue in patients with non‐metastatic breast and prostate cancer.
Methods
Data were retrieved from the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) consortium. Potential moderators were studied with meta‐analyses of pooled individual patient data from 14 randomized controlled trials through linear mixed‐effects models with interaction tests. The analyses were conducted separately in patients with breast (n = 1091) and prostate cancer (n = 1008).
Results
Statistically significant, small overall effects of psychosocial interventions on fatigue were found (breast cancer: β = −0.19 95% confidence interval (95%CI) = −0.30; −0.08; prostate cancer: β = −0.11 95%CI = −0.21; −0.00). In both patient groups, intervention effects did not differ significantly by sociodemographic or clinical characteristics, nor by baseline levels of fatigue or pain. For intervention‐related moderators (only tested among women with breast cancer), statistically significant larger effects were found for cognitive behavioral therapy as intervention strategy (β = −0.27 95%CI = −0.40; −0.15), fatigue‐specific interventions (β = −0.48 95%CI = −0.79; −0.18), and interventions that only targeted patients with clinically relevant fatigue (β = −0.85 95%CI = −1.40; −0.30).
Conclusions
Our findings did not provide evidence that any selected demographic or clinical characteristic, or baseline levels of fatigue or pain, moderated effects of psychosocial interventions on fatigue. A specific focus on decreasing fatigue seems beneficial for patients with breast cancer with clinically relevant fatigue.
•COVID-19 associated with long-lasting symptoms in patients with advanced kidney disease.•Post COVID-19 condition (PCC) occurs in 24% of patients with advanced kidney disease.•Less likelihood of PCC ...if higher SARS-CoV-2 vaccine induced antibody levels.•More likelihood of PCC if previously hospital admitted during COVID-19.
The burden of post COVID-19 condition (PCC) is not well studied in patients with advanced kidney disease.
A large prospective cohort of SARS-CoV-2 vaccinated patients with chronic kidney disease stages G4–G5 (CKD G4/5), on dialysis, and kidney transplant recipients (KTR) were included. Antibody levels were determined after vaccination. Presence of long-lasting symptoms was assessed in patients with and without prior COVID-19 and compared using logistic regression. In patients with prior COVID-19, PCC was defined according to the WHO definition.
Two hundred sixteen CKD G4/5 patients, 375 dialysis patients, and 2005 KTR were included. Long-lasting symptoms were reported in 204/853 (24%) patients with prior COVID-19 and in 297/1743 (17%) patients without prior COVID-19 (aOR: 1.45 (1.17–1.78), P < 0.001). PCC was prevalent in 29% of CKD G4/5 patients, 21% of dialysis patients, and 24% of KTR. In addition, 69% of patients with PCC reported (very) high symptom burden. Odds of PCC was lower per 10-fold increase in antibody level after vaccination (aOR 0.82 0.70–0.96, P = 0.01) and higher in case of COVID-19 related hospital admission (aOR 4.64 2.61–8.25, P = 0.003).
CKD G4/5 patients, dialysis patients, and KTR are at risk for PCC with high symptom burden after SARS-CoV-2 vaccination, especially if antibody levels are low and in case of hospitalization due to COVID-19.
