RESUMEN

The high prevalence of insomnia in cancer patients leads to a significant reduction in the quality of life of those affected. A detailed record of symptoms therefore plays an essential role for further course of treatment. Which screening instruments enable identification of cancer patients with insomnia is the subject of this single-arm nonrandomized study. During the data collection period, cancer patients meeting the following criteria: self-reported tiredness and/or trouble falling or staying asleep or sleeping too much in an electronic patient-reported outcome measurement were enrolled. For further analysis, focus was placed on the Patient Health Questionnaire Depression Scale (PHQ-8), the Minimal Documentation System (MIDOS2) and the Insomnia Severity Index (ISI). Frequency, correlation, and variance analyses were conducted to identify likely predictors of insomnia. Our findings indicate a closer correlation between the screening question pertaining to sleep disorders and the ISI, compared to the question on tiredness and the ISI. The initial recording of sleep-related parameters plays an essential role for cancer patients in order to identify and treat modifiable factors as promptly as possible. For an initial assessment, we recommend asking about trouble falling or staying asleep or sleeping too much.

RESUMEN

Fatigue is a symptom frequently complained about by older people but unfortunately poorly understood given its subjectivity and the lack of a gold standard for its assessment. The purpose of this study was therefore to preliminarily explore agreement among four different fatigue scales in a sample of persons with extreme longevity (PEL), their direct offsprings (DO), and controls (CO) matched for age and sex with DO. κ statistics was used to quantify agreement among four different fatigue scales. The agreement ranged from mild to substantial and almost perfect agreement depending on the group considered. The highest agreement was found between the Multidimensional Assessment of Fatigue scale and the Short Form Health Survey-36-Vitality Subscale in the PEL group (κ 0.820; 95 % CI 0.471-0.947). These preliminary findings may serve as a guide in selecting the most feasible instrument to assess fatigue in future large-scale research and clinical activities involving older people.

RESUMEN

INTRODUCTION: In recent years, euthanasia has been decriminalized or legalized in several countries. The debate on whether to legalize such a practice is open in many places and is a topic that arouses great controversy. Euthanasia has been presented as a response to situations of advanced, incurable, or irreversible disease, or situations that cause intolerable suffering to the person. However, in recent years, the claim has been asserted that this practice does not have to be associated with such situations. It may happen that a person wants to die and asks for help to do so, even if they are not in a specific clinical situation (pathology or condition) but are experiencing advanced age or present 'vital fatigue'. AIM: The objective of this article is to critically analyse the concept 'vital fatigue': define its meaning, its characteristics, its causes, and its consequences in the debate around euthanasia. To do this, a critical review of the main discussions and arguments present in the literature is made. CONCLUSIONS: It is concluded that vital fatigue can be understood as a product or manifestation of an individualistic and productivistic vision of the human being, in which its relational nature and intrinsic value remain in the background. The loss of the meaning of life also influences him. Therefore, in the face of this phenomenon, the most guaranteeing and ethical option is -we believe-accompaniment and holistic care of the person that allows the causal factors to be modulated, without the need to resort to euthanasia.

RESUMEN

El control del comportamiento de la percepción de cansancio a lo largo del macrociclo de entrenamiento en decatlonistas constituye un indicador para la valoración del proceso de asimilación psicofísica del trabajo realizado acorde a la etapa del macrociclo de entrenamiento por la que transita el atleta. Sin embargo, el insuficiente conocimiento sobre el tema en el decatlón ha limitado el uso de este indicador en el control psicológico de la preparación en este deporte. El objetivo de este trabajo consiste en determinar el comportamiento de la percepción de cansancio en las diferentes etapas del macrociclo de entrenamiento, en decatlonistas de la selección nacional de atletismo de Cuba. Es un estudio descriptivo, en el que se aplica la entrevista para un diagnóstico inicial y la Escala de Borg (modificada), para la medición de la percepción de cansancio. Fueron realizadas 416 mediciones de la percepción de cansancio, durante las etapas de preparación física, general, especial y competitiva. Como principales resultados, la percepción de cansancio aumentó en la etapa de preparación física general en una magnitud de 3.48, en la etapa especial en un 3.43 y en la competitiva en un 2.56. La percepción de cansancio en los decatlonistas estudiados aumentó, significativamente, posterior a las cargas de entrenamiento en cada una de las etapas estudiadas y disminuyó, a medida que avanzó el macrociclo de entrenamiento. La etapa competitiva resultó ser aquella de menor cansancio percibido pre- y poscarga, y la de preparación física general, la de mayor aumento en este proceso.

O controle do comportamento da percepção da fadiga ao longo do macrociclo de treinamento em decatletas constitui um indicador para a avaliação do processo de assimilação psicofísica do trabalho realizado de acordo com a etapa do macrociclo de treinamento pela qual o atleta passa. Contudo, o conhecimento insuficiente sobre o tema no decatlo tem limitado a utilização deste indicador no controle psicológico da preparação neste esporte. O objetivo deste trabalho é determinar o comportamento da percepção da fadiga nas diferentes etapas do macrociclo de treinamento, em decatlonistas da seleção cubana de atletismo. Trata-se de um estudo descritivo, no qual é aplicada a entrevista para diagnóstico inicial e a Escala de Borg (modificada) para mensurar a percepção de fadiga. Foram realizadas 416 medidas de percepção de fadiga durante as etapas de preparação física, geral, especial e competitiva. Como principais resultados, a percepção de fadiga aumentou na etapa de preparação física geral em uma magnitude de 3,48, na etapa especial em 3,43 e na etapa competitiva em 2,56. A percepção de fadiga no decatleta estudado aumentou significativamente após as cargas de treinamento em cada uma das etapas estudadas e diminuiu à medida que o macrociclo de treinamento avançava. A etapa competitiva acabou sendo a que apresentou menor fadiga percebida pré e pós-carga, e a etapa de preparação física geral, a que apresentou maior aumento nesse processo.

The control of the behavior of the perception of tiredness throughout the training macrocycle in decathletes constitutes an indicator for the assessment of the process of psychophysical assimilation of the work carried out according to the stage of the training macrocycle through which the athlete goes. However, insufficient knowledge on the subject in the decathlon has limited the use of this indicator in the psychological control of preparation in this sport. The objective of this work is to determine the behavior of the perception of tiredness in the different stages of the training macrocycle, in tiredness of the Cuban national athletics team. It is a descriptive study, in which the interview is applied for an initial diagnosis and the Borg Scale (modified) to measure the perception of tiredness. 416 measurements of the perception of tiredness were carried out during the stages of general, special and competitive physical preparation. As the main results, the perception of tiredness increased in the general physical preparation stage by a magnitude of 3.48, in the special stage by 3.43 and in the competitive stage by 2.56. The perception of tiredness in the decathletes studied increased significantly after the training loads in each of the stages studied and decreased as the training macrocycle progressed. The competitive stage turned out to be the one with the least perceived pre- and post-load tiredness, and the general physical preparation stage was the one with the greatest increase in this process.

RESUMEN

A significant percentage of patients with an inflammatory bowel disease (IBD) encounter fatigue which can profoundly diminish patients' quality of life, particularly during periods of disease remission when gastrointestinal symptoms have receded. Various contributing risk factors have been identified including active inflammation, anemia, psychological, lifestyle and drug-related factors. While addressing these risk factors has been suggested as the initial approach to managing fatigue, a considerable number of patients still experience persisting symptoms, the primary causes of which remain incompletely understood. Recent insights suggest that dysfunction of the gut-brain axis may play a pathogenic role. This review provides an overview of established risk factors for fatigue, alongside emerging perspectives on the role of the gut-brain axis, and potential treatment strategies.

RESUMEN

OBJECTIVE: Both exposure to occupational chemicals and to unusual working hours have well documented effects on health. Determination of occupational exposure limits is, however, usually based on chemical-only exposure and assumes an 8-h workday, 5 days/week and a 40-h work week. A significant proportion of the workforce is exposed to chemicals while working in other work schedules. This review thus aimed to synthesize and evaluate the scientific support for a combined effect of unusual working hours and chemical exposure and, if possible, give recommendations for OEL adjustments to account for unusual working hours. METHODS: The search for articles was made as part of the preparation of a report for the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals. In this report, unusual working hours were categorized as shift work or extended (>8 h) working hours. Inclusion criteria were observational studies in the English language published up to November 2021 in peer-reviewed journals, with explicit metrics of exposure (chemicals and unusual working hours) and of health outcome, and which explicitly tested the association between exposure and outcome. Search engines of seven databases were used. RESULTS: Of the initially 15 400 identified papers, 9 studies published between 1985 and 2021 met the inclusion criteria, 7 of which showed significant associations. Results from a few of the studies, i.e. regarding effects of dust and endotoxin on lung function, effects of acetone on sleep quality and tiredness, effects of carbon disulphide on coronary artery disease and effects of chemicals on spontaneous abortion, suggested more pronounced effects during night shifts compared to during day shifts. DISCUSSION: The reviewed data is considered insufficient to conclude on recommendations for OEL adjustment for shift work. Suggested areas of future studies are mentioned. CONCLUSION: Further studies about the effects of the combined exposure to unusual working hours and chemical exposure are essential for risk assessment, and for recommendation of potential OEL adjustments. What is important about this paper? Effects of chemical agents at the workplace may depend not only on exposure level and duration but also on the time of exposure in relation to the circadian rhythm. This study reviewed the scientific support for a combined effect of unusual working hours and chemical exposure and revealed an obvious need for additional studies regarding the complex interplay of the two different exposures with respect to adverse health effects.

RESUMEN

BACKGROUND: Migraine is a multiphasic neurovascular disorder, where headache can be succeeded by postdromal symptoms. However, there are limited research on postdromal symptoms. This study aimed to investigate the proportion of individuals with migraine from a tertiary care unit reporting postdromal symptoms in adherence with the ICHD-3 definition. We also aimed to examine how the means of enquiry might influence the estimated proportions. Additionally, we explored whether any clinical features might affect the likelihood of reporting postdromal symptoms. Finally, we assessed to what extend the postdromal symptoms might impact the disease burden. METHODS: In a cross-sectional study, we enrolled adult participants diagnosed with migraine who were asked to report their postdromal symptoms (i.e., unprompted reporting). Subsequently, a 16-item list was used to further ascertain the occurrence of postdromal symptoms (i.e., prompted reporting). Clinical characteristics were obtained through a semi-structured interview. Moreover, electronic questionnaires were used to assess the disease burden, i.e., the Six-Item Headache Impact Test (HIT-6), Migraine Disability Assessment (MIDAS), and the World Health Organization Disability Assessment 2.0 (WHODAS 2.0). RESULTS: Among 631 participants with migraine, a higher proportion experienced at least one postdromal symptom when prompted (n = 509 [80.7%]) compared with unprompted reporting (n = 421 [66.7%], P < 0.001). Furthermore, the total number of postdromal symptoms experienced was greater with prompted than unprompted reporting (medians 3 [IQR 1 - 6] versus 1 [IQR 0 - 2]; P < 0.001). Furthermore, the likelihood of reporting postdromal symptoms increased with the presence of premonitory symptoms and decreased with higher number of monthly migraine days. Weak correlations were identified between the number of postdromal symptoms reported and both HIT-6 (ρ = 0.14; P < 0.001) and WHODAS scores (ρ = 0.15; P < 0.001), whilst no correlation was observed with MIDAS score (ρ = 0.08; P = 0.054). CONCLUSIONS: Postdromal symptoms are prevalent in individuals with migraine from a tertiary care unit. However, reported estimates warrant cautious interpretation as they depend on the means of enquiry, presence of premonitory symptoms, and frequency of monthly migraine days. Moreover, a weak correlation was identified between the number of postdromal symptoms and both HIT-6 and WHODAS scores, indicating only a marginal influence on the disease burden.

RESUMEN

BACKGROUND: The aftermath of the COVID-19 pandemic continues to affect millions worldwide, resulting in persisting postvirus complaints and impacting peoples' quality of life. Long COVID, characterized by lingering symptoms like fatigue and mental illness, can extend beyond a few months, necessitating further research to understand its implications. OBJECTIVE: This study aims to quantify the degree of physical and psychological fatigue in patients following COVID-19 infection and examine its correlation with mental health disorders. METHODS: Using a consecutive nonrandom sampling technique, we will conduct a prospective cohort multicenter observational study in 5 Portuguese hospitals. Symptomatic adult patients with previous COVID-19 attending follow-up consultations will be enrolled. We will include patients who had mild, moderate, and severe acute disease. We will assess clinical outcomes related to COVID-19, including the type of respiratory support such as high-flow nasal cannula, noninvasive ventilation, and invasive mechanical ventilation. The exclusion criteria will include previous severe psychiatric disorders confirmed by a psychiatrist; refusal or inability to respond to the questionnaire; concomitant neurological disorder; persistent fatigue symptoms during the 6 months before infection; and the need for invasive mechanical ventilation during COVID-19 infection due to a high prevalence of postintensive care syndrome. Our primary outcome is the prevalence of fatigue in patients with post-COVID-19 depression and/or anxiety, as measured by the Chalder Fatigue Scale (CFQ-11) and the Hospital Anxiety and Depression Scale (HADS). The secondary outcomes will include an assessment of health-related quality of life via the EQ-5D questionnaire and an exploration of the prevalence of symptoms of posttraumatic stress disorder (PTSD) using the 14-item Posttraumatic Stress Scale (PTSS-14). We will also examine the association between mental health symptoms and the severity of acute COVID-19. The post-COVID-19 data will be collected at least 6 months after the positive test and no longer than 9 months during the clinical appointment. RESULTS: We expect our multicenter study on patients post COVID-19 to reveal a significant link between mental illness symptoms and both physical and psychological fatigue. Patients with heightened depression and anxiety may report increased levels of fatigue. Additionally, we expect to find persistent PTSD symptoms in a subset of participants, indicating the enduring psychological impact of the virus. CONCLUSIONS: This study may underscore the need for integrated care addressing physical and mental health in patients post COVID-19. The observed connections emphasize the importance of considering mental well-being for long-term health outcomes. Despite study limitations, our findings contribute valuable insights for future treatment strategies and highlight the necessity for comprehensive mental health support in post-COVID-19 care. This research provides valuable insights into the mental health implications of COVID-19 and its impact on post-COVID-19 fatigue and the overall well-being of affected individuals.

RESUMEN

Excessive daytime sleepiness is a common symptom of sleep disorders. Despite its prevalence, it remains difficult to define, detect, and address. The difficulties surrounding sleepiness have been linked to an ambiguous conceptualization, a large variety of scales and measures, and the overlap with other constructs, such as fatigue. The present study aims to investigate patients' descriptions of sleepiness-related daytime complaints and their phenomenology. We performed semi-directed interviews with patients diagnosed with obstructive sleep apnea (N = 15) or narcolepsy (N = 5). The interviewers took care of utilizing the participants' terminology when describing daytime complaints related to their sleep disorder. Various aspects of the daytime complaints were investigated, such as their description and temporality. The transcribed content was thematically analyzed using an eclectic coding system, yielding five themes. The participants used different interchangeable descriptors (tired, sleepy, fatigued, exhausted) to express their daytime complaints. They enriched their description with indexes of magnitude (ranging from 'not especially' to 'most gigantic, extreme'), oppositions to other states (using antipodes like energy, alertness, wakefulness, or rest), and indications of fluctuations over the day. Interestingly, the participants often used metaphors to express their experiences and their struggles. The lived experiences of the patients were found to not always align with common self-reported monitoring tools of sleepiness and to relate only in part with current conceptions. In practice, it is important to probe daytime complaints, such as daytime sleepiness, with a broader consideration, for example, by exploring antipodes, consequences, and time-of-day fluctuations.

RESUMEN

BACKGROUND: Post-stroke fatigue can manifest as both physical and mental fatigue. The Fatigue Scale for Motor and Cognitive Functions (FSMC) evaluates fatigue on the motor and cognitive domains separately, however, the psychometric properties of this measure in stroke have not been reported. OBJECTIVE: To determine the internal consistency, test-retest reliability, and concurrent validity of the FSMC in chronic stroke. METHODS: Thirty-four participants with chronic stroke (55.26±12.27 years of age; 59.53±89.21 months post-stroke) completed the FSMC on two separate visits. Internal consistency and reliability of the FSMC were examined using Cronbach's alpha and two-way mixed effects intraclass correlation coefficients (ICC), respectively. Correlation between the FSMC and the Fatigue Severity Scale and Visual Analog Scale-Fatigue was used to assess concurrent validity. RESULTS: Internal consistency was excellent (Cronbach's alpha > 0.9) and reliability was moderate to good (ICC = 0.72-0.81) for all FSMC scores. The FSMC demonstrated moderate to good concurrent validity with the Fatigue Severity Scale (ρ= 0.66-0.72) but only fair concurrent validity with the Visual Analog Scale-Fatigue (ρ= 0.37-0.44). CONCLUSION: The FSMC is a valid and reliable measure of post-stroke fatigue and may be a useful tool to examine physical fatigue and cognitive fatigue in chronic stroke.

RESUMEN

Introduction: To extend individuals' healthy life expectancies, the improvement of subjective health and quality of life (QOL) has been increasingly prioritized, alongside the improvement of their physical functioning. Reports have indicated that intake of medium-chain triglycerides (MCTs) benefits the physical health of older individuals requiring nursing care, and athletes, and healthy individuals. But there are few studies investigating the effects of MCTs on subjective health and QOL. The present study sought to evaluate the combined effects of 12-week MCTs supplements and moderate-intensity walking exercise on the subjective health and QOL of middle-aged and older adults aged 60-74 with low BMIs (< 24 kg/m2) and who had no exercise habits. Methods: A placebo-controlled, double-blind, parallel-group trial was conducted. Three MCTs supplement groups with different doses and fatty acid compositions were compared with a control group. The study used the SF-36v2 questionnaire to assess subjective health and health-related QOL (HRQOL). Results: The result showed significant improvements in the scores on subscales of the physical QOL, such as Physical functioning and General health, and summary scores on the mental QOL, compared to the control. Conclusion: It is estimated that the combination of continuous intake of MCTs and walking exercise may affect HRQOL and improve subjective physical and mental health in sedentary, healthy, middle-aged and older adults.

RESUMEN

In early 2020, countries across the world imposed lockdown restrictions to curb the spread of the Covid-19 coronavirus. Lockdown conditions, including social and physical distancing measures and recommended self-isolation for clinically vulnerable groups, were proposed to disproportionately affect those living with chronic pain, who already report reduced access to social support and increased isolation. Yet, empirical evidence from longitudinal studies tracking the effects of prolonged and fluctuating lockdown conditions, and potential psychological factors mediating the effects of such restrictions on outcomes in chronic pain populations, is lacking. Accordingly, in the present 13-wave longitudinal study, we surveyed pain intensity, pain interference, and tiredness in people with chronic pain over the course of 11 months of the Covid-19 pandemic (April 2020-March 2021). Of N = 431 participants at baseline, average completion rate was ∼50% of time points, and all available data points were included in linear mixed models. We examined the impact of varying levels of lockdown restrictions on these outcomes and investigated whether psychological distress levels mediated effects. We found that a full national lockdown was related to greater pain intensity, and these effects were partially mediated by depressive symptoms. No effects of lockdown level were found for pain interference and tiredness, which were instead predicted by higher levels of depression, anxiety, pain catastrophising, and reduced exercise. Our findings are relevant for improving patient care in current and future crises. Offering remote management options for low mood could be particularly beneficial for this vulnerable population in the event of future implementation of lockdown restrictions. PERSPECTIVE: This longitudinal study demonstrates the impact of Covid-19 lockdown restrictions on people with chronic pain. Findings suggest a complex interaction of psychosocial factors that impacted various aspects of pain experience in patients, which offer the potential to inform clinical strategies for remote medicine and future crises.

RESUMEN

This study aimed to describe the level of physical activity and its relation to fatigue and frailty during the COVID-19 pandemic in community-dwelling older adults aged 80 years and over. Three hundred and ninety-one older adults (aged 86.5 ± 3.00) completed a survey including physical activity, the Mobility Tiredness scale, and the FRAIL scale. Linear regression analysis was conducted to assess whether the variables age, sex, and physical activity (independent factors) were significantly related to fatigue and frailty. Respectively, 30.5% and 24.7% of the participants reported a decrease in walking and in energy-intensive activities; 25.4% reported increased sedentary behavior. A lower level of physical activity was associated with higher levels of fatigue and increased frailty risk (p < .05), independently from psychological symptoms. These results are important because participants with lower levels of physical activity and more sedentary behavior are more likely to feel fatigued and have higher risk to be frail.

RESUMEN

Objectives: Fatigue is a frequent and burdensome symptom in patients with advanced disease in palliative care. However, it is under-assessed and undertreated in clinical practice, even though many treatment options have been identified in systematic reviews. Care pathways with defined and standardised steps have been recommended for effective management in the clinical setting. This paper describes a care pathway for managing fatigue in palliative care patients. This study aims to develop a care pathway with detailed guidance for screening, assessment, diagnosis, and treatment of fatigue in palliative care patients. Material and methods: A collaborative effort of multidisciplinary clinicians participated in constructing the care pathway. The care pathway was developed using the following steps: (a) Developing an intervention; (b) piloting and feasibility; (c) evaluating the intervention; (d) reporting; and (e) implementation. This paper covers the first step, which includes the evidence base identification, theory identification/development, and process/outcomes modeling. A literature search was conducted to understand the extent of the fatigue problem in the palliative care setting and identify existing guidelines and strategies for managing fatigue. Consistent recommendations emanating from the included papers were then contributed to a care pathway. Patient representatives and palliative care professionals provided feedback on the draft. Results: The care pathway address the following care processes: (1) Screening for the presence of fatigue; (2) assessment to evaluate the severity of fatigue; (3) diagnostic procedure, including history, physical examination, and laboratory finding; (4) therapeutic management pathway for clinical decision-making; and (5) valuation of treatment effect, using questionnaires, diaries and physical activity monitoring with body-worn sensors. Conclusion: The development of a care pathway will help to implement regular and structured assessment, diagnosis, and treatment of fatigue for healthcare professionals treating palliative care patients. Reviewing the pathway with a multidisciplinary expert group and field testing the pathway will be the next steps toward implementation.

RESUMEN

This review aims to serve as a guide for clinical practice and to appraise the current knowledge on exercise stress echocardiography in the evaluation of intraventricular obstruction in HCM, in patients with cardiac syndrome X, in athletes with symptoms related to exercise, and in patients with normal left ventricular systolic function and exercise-related unexplained tiredness. The appearance of intraventricular obstruction while exercising is considered rare, and it usually occurs in patients with hypertrophy of the left ventricle. The occurrence of intraventricular obstruction when exercising has been evidenced in patients with hypertrophic cardiomyopathy, athletes, patients with cardiac syndrome X, patients with syncope or dizziness related to exercise, and patients with dyspnea and preserved ejection fraction. The clinical significance of this observation and the exercise modality that is most likely to trigger intraventricular obstruction remains unknown. Supine exercise and lying supine after exercise are less technically demanding, but they are also less physiologically demanding than upright exercise. Importantly, in everyday life, human beings generally do not become supine after exercise, as takes place in post-exercise treadmill stress echocardiograms in most echocardiography labs. The presence of induced intraventricular obstruction might be considered when patients have exercise-related symptoms that are not understood, and to assess prognosis in hypertrophic cardiomyopathy.

RESUMEN

Vitamin D supplementation has been considered a possible treatment to reduce the risk of disease activity and progression in people with multiple sclerosis (MS). However, its effect on disease symptoms remains unclear. The aim of this meta-analysis was to conduct a systematic review to assess the effect of vitamin D on fatigue in this population. The systematic review was conducted using the MEDLINE, Cochrane Library, Embase and Web of Science databases from inception to May 2023. Randomized controlled trials (RCTs) reporting pre-post changes in fatigue after vitamin D supplementation were included. Pooled effect sizes and 95% confidence intervals (95% CIs) were calculated by applying a random effects model with Stata/SE (Version 16.0; StataCorp., College Station, TX, USA). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. A total of five studies with 345 individuals (271 females; age range: 25.4-41.1 years) were included. A significant reduction in fatigue was perceived when vitamin D supplementation was compared with a control group: -0.18 (95% CI: -0.36 to -0.01; I2 = 0%). Thus, our findings show that the therapeutic use of vitamin D on fatigue in people with MS could be considered. Nevertheless, due to the lack of agreement on the dose to be applied, it is recommended to use it under medical prescription.

RESUMEN

BACKGROUND: Fatigue and impaired health-related quality of life (HRQoL) are common among kidney transplant recipients (KTR). We hypothesized that both may partially be attributable to poor sleep. METHODS: Cross-sectional and longitudinal data of KTR enrolled in the TransplantLines Biobank and Cohort Study were used. Sleep quality was assessed using the Pittsburgh Sleep Quality Index questionnaire. Individual strength (i.e. a composite of fatigue, concentration, motivation and physical activity), societal participation and HRQoL were assessed using validated questionnaires. RESULTS: We included 872 KTR (39% female, age 56 ± 13 years) and 335 healthy controls. In total, 33% of male KTR and 49% of female KTR reported poor sleep quality, which was higher compared with male and female healthy controls (19% and 28%, respectively, P < .001 for both). In logistic regression analyses, female sex, anxiety, active smoking, low protein intake, physically inactive lifestyle, low plasma magnesium concentration, using calcineurin inhibitors, not using mTOR inhibitors and using benzodiazepine agonists were associated with poor sleep quality. In adjusted linear regression analyses, poor sleep was strongly and independently associated with lower individual strength [standardized ß (st.ß) = 0.59, 95% confidence interval (CI) 0.45 to 0.74, P < .001], poorer societal participation (frequency: st.ß = -0.17, 95% CI -0.32 to -0.01, P = .04; restrictions: st.ß = -0.36, 95% CI -0.51 to -0.21, P < .001; satisfaction: st.ß = -0.44, 95% CI -0.59 to -0.28, P < .001) and lower HRQoL (physical: st.ß = -0.53, 95% CI -0.68 to -0.38, P < .001; mental: st.ß = -0.64, 95% CI -0.78 to -0.50, P < .001). The associations with poorer societal participation and lower HRQoL were strongly mediated by individual strength (P < .001 for all), yet the suggested direct effects of poor sleep quality on HRQoL remained significant (Pphysical = .03, Pmental = .002). Longitudinal data of 292 KTR showed that sleep quality improves after kidney transplantation in males (P < .001), but not in females (P = .9). CONCLUSIONS: Poor sleep quality is common among KTR, and may be a potential target to improve fatigue, societal participation and HRQoL among KTR.

RESUMEN

El estudio se llevó a cabo entre los meses de mayo a julio de 2021. Se recogieron datos de 56 profesionales todos ellos trabajadores del Hospital Universitario Río Hortega de Valladolid (Castilla y León), con el objetivo de describir si los profesionales que eran muestra de estudio presentaban o no riesgo de padecer Síndrome de Burnout (también denominado síndrome del quemado). Se realizó una recolección sistemática de variables utilizando para ello un doble cuestionario que consta de una primera parte en la que se recogen datos sociodemográficos, profesionales e individuales y una segunda parte la cual, es el propio cuestionario Maslach Burnout Inventory (MBI) adaptado al español. Se realizó un estudio transversal y analítico en el que, tras el análisis de los datos recogidos, se obtuvo que la prevalencia de profesionales de la muestra que pueden desarrollar el Síndrome de Burnout en el momento del estudio es del 64,29% (correspondiente a 36 profesionales que presentan al menos en 1 ítem del cuestionario Burnout un resultado “Alto”), lo cual quiere decir que el riesgo de nuestros sanitarios de padecer el Síndrome es alto. Además, se analizaron factores que pueden aumentar o incidir en el riesgo de aparición del Síndrome como son: sexo, edad, número de hijos, estado civil, categoría profesional, tipo de contrato, antigüedad profesional, horario laboral, lugar de trabajo, baja laboral en el último año, horas semanales dedicadas al ocio, existencia de enfermedad crónica, toma de psicofármacos, además de unas preguntas de autopercepción relacionadas con el periodo de pandemia por Covid-19.

RESUMEN

RATIONALE & OBJECTIVE: Prior studies report that the use of proton pump inhibitors (PPIs) can adversely affect gut microbiota and gastrointestinal uptake of micronutrients, in particular iron and magnesium, and are used frequently by kidney transplant recipients. Altered gut microbiota, iron deficiency, and magnesium deficiency have been implicated in the pathogenesis of chronic fatigue. Therefore, we hypothesized that PPI use may be an important and underappreciated cause of fatigue and reduced health-related quality of life (HRQoL) in this population. STUDY DESIGN: Cross-sectional study. SETTING & PARTICIPANTS: Kidney transplant recipients (≥1 year after transplantation) enrolled in the TransplantLines Biobank and Cohort Study. EXPOSURE: PPI use, PPI type, PPI dosage, and duration of PPI use. OUTCOME: Fatigue and HRQoL, assessed using the validated Checklist Individual Strength 20 Revised questionnaire and Short Form-36 questionnaire. ANALYTICAL APPROACH: Logistic and linear regression. RESULTS: We included 937 kidney transplant recipients (mean age 56±13 years, 39% female) at a median of 3 (1-10) years after transplantation. PPI use was associated with fatigue severity (regression coefficient 4.02, 95% CI, 2.18 to 5.85, P<0.001), a higher risk of severe fatigue (OR 2.05, 95% CI, 1.48 to 2.84, P<0.001), lower physical HRQoL (regression coefficient-8.54, 95% CI, -11.54 to-5.54, P<0.001), and lower mental HRQoL (regression coefficient-4.66, 95% CI, -7.15 to-2.17, P<0.001). These associations were independent of potential confounders including age, time since transplantation, history of upper gastrointestinal disease, antiplatelet therapy, and the total number of medications. They were present among all individually assessed PPI types and were dose dependent. Duration of PPI exposure was only associated with fatigue severity. LIMITATIONS: Residual confounding and inability to assess causal relationships. CONCLUSIONS: PPI use is independently associated with fatigue and lower HRQoL among kidney transplant recipients. PPI use might be an easily accessible target for alleviating fatigue and improving HRQoL among kidney transplant recipients. Further studies examining the effect of PPI exposure in this population are warranted. PLAIN-LANGUAGE SUMMARY: In this observational study, we investigated the association of proton pump inhibitors with fatigue and health-related quality of life among kidney transplant recipients. Our data showed that proton pump inhibitors were independently associated with fatigue severity, severe fatigue, and lower physical and mental health-related quality of life. These associations were present among all individually assessed proton pump inhibitor types and were dose dependent. While we await future studies on this topic, proton pump inhibitor use might be an easily accessible target for alleviating fatigue and improving health-related quality of life among kidney transplant recipients.

RESUMEN

BACKGROUND: Cancer-related fatigue (CRF) is one of the most common symptoms in patients with cancer. However, CRF has not been sufficiently evaluated as it involves various factors. In this study, we evaluated fatigue in patients with cancer receiving chemotherapy in an outpatient setting. METHODS: Patients with cancer receiving chemotherapy at the outpatient treatment center of Fukui University Hospital and Saitama Medical University Medical Center Outpatient Chemotherapy Center were included. The survey period was from March 2020 to June 2020. The frequency of occurrence, time, degree, and related factors were examined. All patients were asked to fill out the Edmonton Symptom Assessment System Revised Japanese version (ESAS-r-J) questionnaire, which is a self-administered rating scale, and patients with ESAS-r-J "Tiredness" scores of ≥ 3 were evaluated for factors related to tiredness, such as age, sex, weight, and laboratory parameters. RESULTS: A total of 608 patients were enrolled in this study. Fatigue after chemotherapy occurred in 71.0% of patients. ESAS-r-J "Tiredness" scores of ≥ 3 were observed in 20.4% of patients. The factors related to CRF were low hemoglobin level and high C-reactive protein level. CONCLUSIONS: Twenty percent of patients receiving cancer chemotherapy on an outpatient basis had moderate or severe CRF. Patients with anemia and inflammation are at increased risk of developing fatigue after cancer chemotherapy.
