Abstract
The 'Oslo Chronic Fatigue Consortium' consists of researchers and clinicians who question the current narrative that chronic fatigue syndromes, including post-covid conditions, are incurable diseases. Instead, we propose an alternative view, based on research, which offers more hope to patients. Whilst we regard the symptoms of these conditions as real, we propose that they are more likely to reflect the brain's response to a range of biological, psychological, and social factors, rather than a specific disease process. Possible causes include persistent activation of the neurobiological stress response, accompanied by associated changes in immunological, hormonal, cognitive and behavioural domains. We further propose that the symptoms are more likely to persist if they are perceived as threatening, and all activities that are perceived to worsen them are avoided. We also question the idea that the best way to cope with the illness is by prolonged rest, social isolation, and sensory deprivation.Instead, we propose that recovery is often possible if patients are helped to adopt a less threatening understanding of their symptoms and are supported in a gradual return to normal activities. Finally, we call for a much more open and constructive dialogue about these conditions. This dialogue should include a wider range of views, including those of patients who have recovered from them.

Abstract
Fatigue surrounding hemodialysis treatments is a common and often debilitating symptom that impacts patients' quality of life. Intradialytic fatigue develops or worsens immediately before hemodialysis and persists through the dialysis treatment. Little is known about associated risk factors or pathophysiology, although it may relate to a classic conditioning response. Postdialysis fatigue (PDF) develops or worsens after hemodialysis and may persist for hours. There is no consensus on how to measure PDF. Estimates for the prevalence of PDF range from 20%-86%, likely due to variation in methods of ascertainment and participant characteristics. Several hypotheses seek to explain the pathophysiology of PDF, including inflammation, hypothalamic-pituitary-adrenal axis dysregulation, and osmotic and fluid shifts, but none is currently supported by compelling or consistent data. PDF is associated with several clinical factors, including cardiovascular and hemodynamic effects of the dialysis procedure, laboratory abnormalities, depression, and physical inactivity. Clinical trials have reported hypothesis-generating data about the utility of cold dialysate, frequent dialysis, clearance of large middle molecules, treatment of depression, and exercise as potential treatments. Existing studies are often limited by sample size, lack of a control group, observational design, or short intervention duration. Robust studies are needed to establish the pathophysiology and management of this important symptom.

Abstract
Abstract. Many disturbances of physical, social, and mental health have conditions involving lack of energy, difficulty in making decisions, and low interest or motivation. Laboratory studies of willpower depletion have produced similar states in a temporary fashion. The present review uses extant literature to develop and test three theories about how temporary states of low willpower could become chronic. The first is ongoing and repeated exposure to depleting circumstances, such as caregiver fatigue, burdensome financial debts, and high-stress jobs. The second focuses on inadequate recoveries, such as poor sleep, insufficient nutrition, or unsatisfying vacations. The third invokes dispositional vulnerabilities that predispose some people to become depleted more frequently than others. A wide-ranging search for evidence concluded that the first two theories have more support than the third, though all further merit research. Additional possible contributions to chronicity are discussed, such as the emergence of vicious circles.

A unified Internet-delivered exposure treatment for undifferentiated somatic symptom disorder: single-group prospective feasibility trial. Pilot Feasibility Stud 2022; 8:149. [PMID: 35854392 PMCID: PMC9294766 DOI: 10.1186/s40814-022-01105-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 06/24/2022] [Indexed: 12/09/2022] Open
Abstract
BACKGROUND Exposure-based psychological treatment appears to have beneficial effects for several patient groups that commonly report distress related to persistent somatic symptoms. Yet exposure-based treatment is rarely offered in routine care. This may be because existing treatment protocols have been developed for specific symptom clusters or specific unwanted responses to somatic symptoms, and many clinics do not have the resources to offer all these specialised treatments in parallel. In preparation for a randomised controlled trial, we investigated the feasibility of a new and unified Internet-delivered exposure treatment (OSF.io: cnbwj) for somatic symptom disorder regardless of somatic symptom domain (e.g. cardiopulmonary, fatigue, gastrointestinal, pain), combination of unwanted emotions (e.g. anger, anxiety, fear, shame) and whether somatic symptoms are medically explained or not. We hypothesised that a wide spectrum of subgroups would show interest, that the treatment would be rated as credible, that adherence would be adequate, that the measurement strategy would be acceptable and that there would be no serious adverse events. METHODS Single-group prospective cohort study where 33 self-referred adults with undifferentiated DSM-5 somatic symptom disorder took part in 8 weeks of unified Internet-delivered exposure treatment delivered via a web platform hosted by a medical university. Self-report questionnaires were administered online before treatment, each week during treatment, post treatment and 3 months after treatment. RESULTS Participants reported a broad spectrum of symptoms. The Credibility/Expectancy mean score was 34.5 (SD = 7.0, range: 18-47). Participants completed 91% (150/165) of all modules and 97% of the participants (32/33) completed at least two exposure exercises. The average participant rated the adequacy of the rationale as 8.4 (SD = 1.5) on a scale from 0 to 10. The post-treatment assessment was completed by 97% (32/33), and 84% (27/32) rated the measurement strategy as acceptable. The Client Satisfaction Questionnaire mean score was 25.3 (SD = 4.7, range: 17-32) and no serious adverse events were reported. Reductions in subjective somatic symptom burden (the Patient Health Questionnaire 15; d = 0.90) and symptom preoccupation (the somatic symptom disorder 12; d = 1.17) were large and sustained. CONCLUSIONS Delivering a unified Internet-delivered exposure-based treatment protocol for individuals with undifferentiated somatic symptom disorder appears to be feasible.

Abstract
Little is understood about individual difference factors related to e-cigarette expectancies about use. This study examined the interactive effects of fatigue severity and anxiety sensitivity in relation to e-cigarette expectancies among 525 e-cigarette users (51.0% female, Mage = 35.25 years, standard deviation = 10.10). Results indicated a significant interaction between fatigue severity and anxiety sensitivity in terms of positive expectancies (β = 0.57, p < 0.001, 95% confidence interval = (0.002, 0.01)), but not for negative expectancies (β = 0.25, p = 0.08, 95% confidence interval = (0, 0.005)) for e-cigarette use. These results support anxiety sensitivity as a moderator in the relation between fatigue severity and positive outcome expectancies for e-cigarette use.

Abstract
BACKGROUND AND OBJECTIVES Fatigue is an adaptive state after prolonged effort and often goes hand in hand with changes in behavior and motivation, such as the urge to stop exerting further effort. However, fatigue may become chronic in nature, as seen in multiple psychiatric disorders and chronic diseases, thereby losing its adaptive function. The etiology of fatigue symptoms remains poorly understood. We aimed to investigate whether nocebo information about the fatigue inducing nature of a cognitive task may contribute to the experience of fatigue and the motivational urge to stop. METHODS Participants (N = 46) repeatedly rated currently experienced fatigue while engaging in cognitive effort (working memory task). Crucially, half of participants received nocebo instructions prior to this task, whereas the other half only received neutral information. RESULTS Over the entire sample, results showed an increase in fatigue and urge to stop as the task progressed. Crucially, participants in the nocebo condition reported a higher urge to stop throughout the task relative to participants in the neutral condition. No significant effects were found for fatigue. Interestingly however, after controlling for baseline differences between conditions in negative affect, there was a significant Condition*Task block interaction effect on fatigue. LIMITATIONS Limitations include the relatively short experimental protocol and the underrepresentation of male relative to female participants. CONCLUSIONS These findings suggest that heightened awareness among clinicians and therapists about potential nocebo effects in their communication is warranted.

Associations between Depression, Anxiety, Fatigue, and Learning Motivating Factors in e-Learning-Based Computer Programming Education. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18179158. [PMID: 34501748 PMCID: PMC8431325 DOI: 10.3390/ijerph18179158] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 08/25/2021] [Accepted: 08/26/2021] [Indexed: 12/16/2022]
Abstract
Quarantines imposed due to COVID-19 have forced the rapid implementation of e-learning, but also increased the rates of anxiety, depression, and fatigue, which relate to dramatically diminished e-learning motivation. Thus, it was deemed significant to identify e-learning motivating factors related to mental health. Furthermore, because computer programming skills are among the core competencies that professionals are expected to possess in the era of rapid technology development, it was also considered important to identify the factors relating to computer programming learning. Thus, this study applied the Learning Motivating Factors Questionnaire, the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder Scale-7 (GAD-7), and the Multidimensional Fatigue Inventory-20 (MFI-20) instruments. The sample consisted of 444 e-learners, including 189 computer programming e-learners. The results revealed that higher scores of individual attitude and expectation, challenging goals, clear direction, social pressure, and competition significantly varied across depression categories. The scores of challenging goals, and social pressure and competition, significantly varied across anxiety categories. The scores of individual attitude and expectation, challenging goals, and social pressure and competition significantly varied across general fatigue categories. In the group of computer programming e-learners: challenging goals predicted decreased anxiety; clear direction and challenging goals predicted decreased depression; individual attitude and expectation predicted diminished general fatigue; and challenging goals and punishment predicted diminished mental fatigue. Challenging goals statistically significantly predicted lower mental fatigue, and mental fatigue statistically significantly predicted depression and anxiety in both sample groups.

Abstract
BACKGROUND Using a laboratory-based exercise task, this study investigated objective exercise performance as well as expectations, anxiety and perceived task performance ratings in adolescents with CFS compared to healthy controls and illness controls. METHOD Trials of a sit-stand exercise task (SST) were undertaken (CFS: n = 61, asthma (AS): n = 31, healthy adolescents (HC): n = 78). Adolescents rated their expectations, pre- and post-task anxiety, and perceived task difficulty. Their parents independently rated their performance expectations of their child. RESULTS The CFS group took significantly longer to complete the SST than the AS group (MD 3.71, 95% CI [2.41, 5.01] p < .001) and HC (MD 3.61, 95% CI [2.41, 4.81], p < .001). Adolescents with CFS had lower expectations for their performance on the exercise task than AS participants (MD -11.79, 95% CI [-22.17, -1.42] p = .022) and HC (MD -15.08, 95% CI [-23.01, -7.14] p < .001). They rated their perceived exertion as significantly greater than AS (MD 3.04, 95% CI [1.86, 4.21] p < .001) and HC (MD 2.98, 95% CI [1.99, 3.98], p < .001). The CFS group reported greater anxiety pre-task than AS (MD 14.11, 95% CI [5.57, 22.65] p < .001) and HC (MD 11.19, 95% CI [2.64, 19.75], p. = 007). Parental group differences showed similar patterns to the adolescents''. CONCLUSIONS Lower expectations and greater anxiety regarding exercise may reflect learning from previous difficult experiences which could impact future exercise performance. Further examination of pre-exercise expectations and post-exercise appraisals could improve our understanding of the mechanisms by which fatigue is maintained.

Schisantherin A improves learning and memory abilities partly through regulating the Nrf2/Keap1/ARE signaling pathway in chronic fatigue mice. Exp Ther Med 2021; 21:385. [PMID: 33680107 PMCID: PMC7918174 DOI: 10.3892/etm.2021.9816] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Accepted: 07/31/2020] [Indexed: 02/07/2023] Open
Abstract
Chronic fatigue is frequently accompanied by decreased learning and memory capabilities. Schizantherin A (SCA) is one of the main active monomer components in Schisandra chinensis lignans. In the present study, a chronic fatigue mouse model was established using the exhausted swimming approach to investigate the effects of SCA on learning and memory and its associated mechanism of action. Learning and memory abilities were tested by step through tests and water maze methods. Levels of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and malondialdehyde (MDA) in hippocampal tissue were measured by corresponding assays. The effect of SCA on the expression of kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), Bcl2, Bax and cleaved caspase-3 were determined by western blot. The present results showed that SCA can improve the learning and memory capabilities of chronic fatigue mice. SCA was found to increase the activities of SOD and CAT in addition to increasing the levels of GSH but reduced the levels of MDA in hippocampus tissues. Furthermore, SCA treatment downregulated the protein expression levels of Keap1, Bax and cleaved caspase-3 and upregulated the protein expression levels of Nrf2, HO1 and Bcl2 in the hippocampus. These results suggested that modulations in the Nrf2-Keap1-antioxidant response element pathway, anti-oxidative and anti-apoptosis effects are the causes underlying the improvements from SCA treatment on the learning and memory abilities of chronic fatigue mice.

Cognitive Behavioral Therapy Improves Physical Function and Fatigue in Mild and Moderate Chronic Fatigue Syndrome: A Consecutive Randomized Controlled Trial of Standard and Short Interventions. Front Psychiatry 2021; 12:580924. [PMID: 33912079 PMCID: PMC8071989 DOI: 10.3389/fpsyt.2021.580924] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 03/17/2021] [Indexed: 01/29/2023] Open
Abstract
Objective: To study whether standard cognitive behavioral therapy (CBT) and a shorter, interpersonal oriented cognitive behavioral therapy (I-CBT) can improve physical function and fatigue in patients diagnosed with mild to moderate chronic fatigue syndrome (CFS) in a multidisciplinary fatigue clinic. Design: Consecutively 236 participants 18-62 years old meeting the Centre of Decease Control, CDC 1994 criteria, with a subsample also fulfilling the Canadian criteria for CFS, were randomly allocated to one of three groups. Two intervention groups received either 16 weeks of standard CBT or 8 weeks of I-CBT vs. a waiting-list control group (WLC). Primary outcome was the subscale Physical Function (PF) from SF-36 (0-100). Secondary outcome was amongst others fatigue measured by Chalder Fatigue Questionnaire (CFQ) (0-33). Outcomes were repeatedly measured up to 52 weeks from baseline. Results: The additional effect relative to baseline at post-intervention for SF-36 physical function was 14.2 (95% CI 7.9-20.4 p < 0.001) points higher for standard CBT and 6.8 (0.5-13.2 p = 0.036) points higher for I-CBT compared with the control group. The additional effect relative to baseline at post-intervention for fatigue was 5.9 (95% CI 0.5-10.5 p = 0.03) points lower for standard CBT compared with the control group but did not differ substantially for I-CBT 4.8 (95% CI -0.4 to 9.9 p = 0.07). The positive change in physical function persisted at 1-year follow-up for both treatment groups, and for standard CBT also in fatigue. The two intervention groups did not differ significantly in self-reported physical function and fatigue at the 1-year follow-up. No serious adverse reactions were recorded in any of the groups during the trial period. Interpretation: A 16-week standard, individual CBT intervention improves physical function and fatigue in CFS outpatients with mild to moderate disease. A shorter 8-week I-CBT program improves physical function. Both treatments are safe, and the effect persist 1 year after baseline.

Abstract
OBJECTIVE Central sensitization is present in different pain conditions, including chronic whiplash-associated disorders. In the absence of a gold standard method of assessment to determine the presence of central sensitization, quantitative sensory testing is currently understood as an optimal proxy. Laboratory sensory testing is, however, not feasible in clinical practice, and the Central Sensitization Inventory was developed as an alternative. The aim of the current study was to evaluate the convergent validity of the Central Sensitization Inventory in chronic whiplash-associated patients by determining the association between the Central Sensitization Inventory and quantitative sensory testing, pain intensity, fatigue, and psychosocial factors. METHODS A total of 125 chronic whiplash-associated patients completed multiple questionnaires and were subjected to pressure pain thresholds and temporal summation. RESULTS . The Central Sensitization Inventory showed a strong association with constructs of general psychopathology, anxiety, distress, depression, and somatization in chronic whiplash-associated disorders. Moderate correlations were found with fatigue and intrusive and avoidant phenomena after a variety of traumatic events. No significant association was found between the Central Sensitization Inventory and pressure pain thresholds and temporal summation, nor between the Central Sensitization Inventory and other pain measurements. CONCLUSIONS Overall, we found that the Central Sensitization Inventory is better in identifying the psychosocial factors related to central sensitization in chronic whiplash-associated disorders than the central nervous system adaptations. Thus, the convergent validity of the Central Sensitization Inventory appears to be only partially present in chronic whiplash-associated disorders.

Abstract
Placebo and nocebo effects are, respectively, the helpful and harmful treatment effects that do not arise from active treatment components. These effects have thus far been researched most often in pain. It is not yet clear to what extent these findings from pain can be generalized to other somatic symptoms. This review investigates placebo and nocebo effects in four other highly prevalent symptoms: dyspnea, fatigue, nausea, and itch. The role of learning mechanisms (verbal suggestions, conditioning) in placebo and nocebo effects on various outcomes (self-reported, behavioral, and physiological) of these different somatic symptoms is explored. A search of experimental studies indicated that, as in pain, the combination of verbal suggestion and conditioning is generally more effective than suggestion alone for evoking placebo and nocebo effects. However, conditioning appears more and verbal suggestions less relevant in symptoms other than pain, with the exception of placebo effects on fatigue and nocebo effects on itch. Physiological measures, such as heart rate, lung function, or gastric activity, are rarely affected even when self-reported symptoms are. Neurobiological correlates are rarely investigated, and few commonalities appear across symptoms. Expectations generally predict placebo and nocebo effects for dyspnea and itch but seem less involved in fatigue and nausea. Individual characteristics do not consistently predict placebo or nocebo effects across symptoms or studies. In sum, many conclusions deriving from placebo and nocebo pain studies do appear to apply to other somatic symptoms, but a number of important differences exist. Understanding what type of learning mechanisms for which symptom are most likely to trigger placebo and nocebo effects is crucial for generalizing knowledge for research and therapies across symptoms and can help clinicians to optimize placebo effects in practice.

Abstract
OBJECTIVE To determine which variables predicted long-term outcome after cognitive behavioral therapy (CBT) for chronic fatigue syndrome (CFS). METHODS A cohort of 511 CFS patients from four different CBT for CFS studies, i.e. two cohort studies and two RCT's. Before treatment, all patients fulfilled the 2003 US CDC criteria for CFS and treated with CBT, were assessed at long-term follow-up, up to 10 years after end of treatment. We tried to predict fatigue severity and physical functioning at follow-up with demographics, cognitive-behavioral perpetuating factors, and CFS characteristics as predictors in linear regression analyses. Logistic regression analysis was used to explore significant predictors of fatigue scores within normal limits at long-term follow-up. RESULTS Lower fatigue severity at long-term follow-up was predicted by a shorter duration of CFS symptoms and lower fatigue levels at baseline, and lower frustration in response to fatigue and lower fatigue levels directly post-treatment. Fatigue scores within normal limits at follow-up was predicted by lower fatigue severity and lower levels of frustration in response to fatigue, both assessed directly post-treatment. Better physical functioning at follow-up was predicted by higher sense of control over fatigue, better physical functioning at post-treatment, and being younger at baseline. In some of the additional analysis pain at baseline also predicted physical functioning at follow-up. CONCLUSION The finding that lower fatigue severity and higher physical functioning at long-term follow-up were positively associated with its outcomes at post-treatment underline the importance of fully maximizing the positive effects of CBT for the sustainment of outcomes. Furthermore, augmenting sense of control and starting treatment sooner after diagnosing CFS could positively influence long-term outcome. Interventions aimed at pain management deserve more attention in research.

Abstract
OBJECTIVE Acute Epstein-Barr virus (EBV) infection is a known trigger of both acute and chronic fatigue. The aim of this study was to investigate associations to fatigue in adolescents with EBV infection during the initial stage and six months after, as well as in healthy controls. METHODS 200 adolescents (12-20 years old) with EBV infection were assessed as soon as possible after the onset of symptoms (EBVbaseline) and six months later (EBVsix months, 5 drop-outs). Also, 70 healthy controls (HC) were included. Associations between current fatigue and 148 different variables (including symptoms, functional abilities and biomarkers) were investigated separately for EBVbaseline, EBVsix months and HC using linear regression modelling. RESULTS Fatigue was associated with symptoms of sleeping difficulties, negative emotions, and quality of life under all circumstances. Fatigue was independently associated with markers of immune response at EBVsix months and in HC, not at EBVbaseline. An association between fatigue and markers of autonomic cardiovascular control was only present at EBVsix months. Cognitive functioning shifted from a positive association to fatigue at EBVbaseline to a negative trend at EBVsix months. Markers of infection were not associated with fatigue at EBVbaseline, EBVsix months nor in HC. CONCLUSION Irrespective of the cause, fatigue is important for quality of life and is highly associated with negative emotions. Markers of infection and immune response had respectively none and barely any association to fatigue. Autonomic alterations and cognitive dysfunction were exclusively associated with fatigue long after infection, corroborating findings from studies of the Chronic Fatigue Syndrome.

Abstract
CONTEXT Fatigue is one of the most prevalent symptoms among hemodialysis (HD) patients. To design effective treatments, it is crucial to understand the diurnal pattern of fatigue in this population. OBJECTIVES The objectives of this study were to assess diurnal changes in fatigue in patients undergoing hemodialysis and their relation with depressive symptoms and to explore whether fatigue may become a classically conditioned response to the hospital environment. METHODS A prospective, observational study was conducted in 51 HD patients. Subjects repeatedly rated their current fatigue on three different days during one week of hemodialysis treatment to capture changes in momentary fatigue. First, on an HD treatment day, fatigue was measured one hour before and immediately before dialysis, as well as immediately after dialysis and again at 22:00 pm Second, on the postdialysis day and on the seventh weekday (when patients had not received treatment on the previous day), fatigue was measured at the same moments in time as the two measurements before dialysis on the treatment day. Beck Depression Inventory-II and Fatigue Severity Scale were administered to evaluate depressive mood and fatigue severity in daily life. RESULTS Fatigue increased as a result of hemodialysis treatment over the entire sample. However, diurnal fatigue patterns differed significantly between individuals high and low in depressive symptoms, with the former being fatigued more constantly throughout the day, and the latter experiencing increases in fatigue due to treatment. Pretreatment fatigue experienced in the hospital environment followed a pattern consistent with the development of a classically conditioned response. CONCLUSION Diurnal fatigue patterns during hemodialysis treatment are associated with depressive symptoms, and classical conditioning may play a role in the experience of pretreatment fatigue.

Abstract
INTRODUCTION Acute Epstein-Barr virus (EBV) infection is a trigger of chronic fatigue and Chronic Fatigue Syndrome (CFS). This study investigated baseline predictors of chronic fatigue six months after an acute EBV infection. MATERIALS AND METHODS A total of 200 adolescents (12-20 years old) with acute EBV infection were assessed for 149 possible baseline predictors and followed prospectively. We performed linear regression to assess possible associations between baseline predictors and fatigue (Chalder Fatigue Questionnaire total score) six months after the acute EBV infection. A total of 70 healthy controls were included for cross-sectional reference. This study is part of the CEBA-project (Chronic fatigue following acute Epstein-Barr virus infection in adolescents). RESULTS In the final multiple linear regression model, fatigue six months after acute EBV infection was significantly and independently predicted by the following baseline variables (regression coefficient B[95% CI]): Sensory sensitivity (0.8[0.09-1.6]), pain severity (0.2[0.02-0.3]), functional impairment (1000 steps/day) (-0.3[-0.5 to -0.08]), negative emotions (anxiety) (0.4[0.2-0.6]), verbal memory (correct word recognition) (1.7[0.1-3.3]), plasma C-reactive protein (2.8[1.1-4.4] for CRP values >0.86) and plasma Vitamin B12 (-0.005[-0.01 to -0.001]). CONCLUSIONS Development of fatigue after acute EBV infection is to a larger extent predicted by baseline variables related to symptoms and functions than to baseline variables reflecting infectious and immune processes.
