Time-dependent complexity characterisation of activity patterns in patients with Chronic Fatigue Syndrome

BACKGROUND

Chronic Fatigue Syndrome patients suffer from symptoms that cannot be explained by a single underlying biological cause. It is sometimes claimed that these symptoms are a manifestation of a disrupted autonomic nervous system. Prior works studying this claim from the complex adaptive systems perspective, have observed a lower average complexity of physical activity patterns in chronic fatigue syndrome patients compared to healthy controls. To further study the robustness of such methods, we investigate the within-patient changes in complexity of activity over time. Furthermore, we explore how these changes might be related to changes in patient functioning.

METHODS

We propose an extension of the allometric aggregation method, which characterises the complexity of a physiological signal by quantifying the evolution of its fractal dimension. We use it to investigate the temporal variations in within-patient complexity. To this end, physical activity patterns of 7 patients diagnosed with chronic fatigue syndrome were recorded over a period of 3 weeks. These recordings are accompanied by physicians' judgements in terms of the patients' weekly functioning.

RESULTS

We report significant within-patient variations in complexity over time. The obtained metrics are shown to depend on the range of timescales for which these are evaluated. We were unable to establish a consistent link between complexity and functioning on a week-by-week basis for the majority of the patients.

CONCLUSIONS

The considerable within-patient variations of the fractal dimension across scales and time force us to question the utility of previous studies that characterise long-term activity signals using a single static complexity metric. The complexity of a Chronic Fatigue Syndrome patient's physical activity signal does not suffice to characterise their high-level functioning over time and has limited potential as an objective monitoring metric by itself.

Nocturia in Menopausal Women: The Link Between Two Common Problems of the Middle Age

INTRODUCTION AND HYPOTHESIS

The aim of this review is to discuss the link between menopause and nocturia and to give an overview of the increasing prevalence, risk factors, causative factors, treatment needs and options for nocturia in peri-menopausal women.

METHODS

This opinion article is a narrative review based on the expertise and consensus of a variety of key opinion leaders, in combination with an extensive literature review. This literature search included a thorough analysis of potential publications on both the PubMed Database and the Web of Science and was conducted between November 2022 and December 2022. The following key words were used "nocturia" and "menopause" or "nocturnal frequency and menopause." Moreover, key words including "incidence," "prevalence," "insomnia," "estrogen therapy," "metabolic syndrome," and "hot flushes" were used in combination with the aforementioned key words. Last, the reference lists of articles obtained were screened for other relevant literature.

RESULTS

The perimenopause can be a trigger for inducing nocturia. Typically, obesity, body mass index (BMI), and waist circumference are risk factors for developing peri-menopausal nocturia. Presumably the development of peri-menopausal nocturia is multifactorial, with interplay among bladder, sleep, and kidney problems due to estrogen depletion after the menopause. First, impaired stimulation of estrogen receptors in the urogenital region leads to vaginal atrophy and reduced bladder capacity. Moreover, menopause is associated with an increased incidence of overactive bladder syndrome. Second, estrogen deficiency can induce salt and water diuresis through blunted circadian rhythms for the secretion of antidiuretic hormone and the activation of the renin-angiotensin-aldosterone system. Additionally, an increased incidence of sleep disorders, including vasomotor symptoms and obstructive sleep apnea signs, is observed. Oral dryness and a consequent higher fluid intake are common peri-menopausal symptoms. Higher insulin resistance and a higher risk of cardiovascular diseases may provoke nocturia. Given the impact of nocturia on general health and quality of life, bothersome nocturia should be treated. Initially, behavioral therapy should be advised. If these modifications are inadequate, specific treatment should be proposed. Systemic hormone replacement is found to have a beneficial effect on nocturia, without influencing sodium and water clearance in patients with nocturnal polyuria. It is presumed that the improvement in nocturia from hormonal treatment is due to an improvement in sleep disorders.

Is the insomnia phenotype the common denominator in LUTS during transition periods? An expert NOPIA research group review

AIMS

As people age, sleep stages and characteristics transition over time, but sleep deficits can profoundly impact health and cognitive functioning. Chronic sleep deprivation is linked to impaired attention and productivity, weakened immunity, increased risk of cardiovascular disease, obesity, and mental health disorders. Insomnia, obstructive sleep apnea syndrome, hormonal changes, nocturia, neurological disorders, and life events interfere with sleep patterns and some are linked to lower urinary tract symptoms (LUTS). This NOPIA symposium on Lifelong LUTS aimed to analyze the literature on associations between sleep and LUTS, generate ideas for future research, and explore whether there is support for the concept of lifelong LUTS in relation to changes in sleep throughout the lifespan.

METHODS

An international panel of experts took part in an online meeting addressing the role of lifelong LUTS in relationship to sleep and the brain organized by the NOPIA research group. The manuscript summarizes existing literature, hypotheses, future research ideas, and clinical recommendations.

RESULTS

Insomnia, sleep fragmentation, hyperarousal, and sensory processing disorders emerged as potential factors in the relationship between sleep and LUTS. Insomnia is often a persistent factor and may have been the initial symptom; however, it is often unrecognized and/or unaddressed in healthcare settings. By recognizing insomnia as a primary driver of various health issues, including nocturia, transitional care aims to address root causes and underlying problems earlier to initiate appropriate treatment.

CONCLUSIONS

A multidisciplinary approach with collaboration between healthcare professionals from various disciplines, such as urology, sleep medicine, gynecology, pediatrics, and geriatrics, is needed and should include validated measurements such as the insomnia severity index and sleep and voiding diaries. Ensuring ongoing follow-up and monitoring through transitional care is crucial for individuals with persistent sleep problems and LUTS, allowing issues that arise or fluctuate over the lifespan to be addressed.

From nocturnal awakenings to nocturnal voiding: the relationship between insomnia and nocturia - a systematic review

INTRODUCTION

The aim of this study was to systematically evaluate relevant literature regarding 1) the prevalence of nocturia in patients with insomnia; 2) sleep characteristics of insomniacs with and without nocturia; 3) interventions for the treatment of insomnia and their effect on nocturia.

EVIDENCE ACQUISITION

A systematic review of literature was performed through EMBASE, MEDLINE, CLINICALTRIALS.GOV and CENTRAL databases up until November 2022 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. From the identified reports, 11 studies were retained, of which 7 were eligible for meta-analysis. Bias assessment was performed using the ROBINS tools as per the Cochrane collaboration guidelines.

EVIDENCE SYNTHESIS

A total of 5396 older adults were included in the meta-analysis. The pooled estimate of the OR was 1.958 (95% CI: 1.609-2.384) for nocturia in patients with insomnia based on 7 studies in a random effects model with nonsignificant heterogeneity (I2=50.83%, P=0.06). Wake after sleep onset (WASO) was longer in people with insomnia and nocturia compared to those without and sleep efficiency (SE) declined. Interventions with melatonin, diet and behavioral therapy were beneficial on nocturia frequency in insomniacs. A limiting factor of our analysis was the scarcity of available data, potentially causing an important selection bias.

CONCLUSIONS

The overall odds for nocturia in older adults is higher in patients with insomnia than those without and is associated with worse sleep outcomes. Interventions for treating insomnia such as melatonin, behavioral therapy and diet show beneficial results on nocturnal voiding frequency. We advocate for further research in which uniform definitions and questionnaires are used. Routine screening for nocturia in patients with insomnia could be beneficial to maximize sleep quality improvement.

Education on medically unexplained symptoms: a systematic review with a focus on cultural diversity and migrants

BACKGROUND

Health care providers often struggle with the management of patients with medically unexplained symptoms (MUS), especially in case of a different ethnicity and/or cultural background. These challenges are insufficiently addressed in their training.

OBJECTIVES

A systematic review on education in the field of MUS in a diverse context to improve MUS healthcare provider-patient interaction focused on intercultural communication.

METHODS

Screening of PubMed, Web of Science, Cinahl and Cochrane Library on the keywords 'Medical unexplained (physical) symptoms (MUS)', 'Somatoform disorder', 'Functional syndrome', 'Diversity', 'Migrants', 'Ethnicity', 'Care models', 'Medical education', 'Communication skills', 'Health literacy'.

RESULTS

MUS patients, especially with a different ethnic background, often feel not understood or neglected. Health care providers experience feelings of helplessness, which may provoke medical shopping and resource consumption. Attitudes and perceptions from undergraduate trainees to senior physicians tend to be negative, impacting on the quality of the patient/health care provider relationship and subsequently on health outcomes, patient satisfaction and therapeutic adherence. Current undergraduate, graduate and postgraduate education and training does not prepare health care providers for diagnosing and managing MUS patients in a diverse context. A continuum of training is necessary to achieve a long term and lasting change in attitudes towards these patients and trainers play a key role in this process. Hence, education should pay attention to MUS, requiring a specific competency profile and training, taken into account the variety in patients' cultural backgrounds.

CONCLUSIONS

This systematic review identified significant gaps and shortcomings in education on MUS in a diverse context. These need to be addressed to improve outcomes.

Epidemiology and organisation of care in medically unexplained symptoms: A systematic review with a focus on cultural diversity and migrants

BACKGROUND

Since the pathophysiology of medically unexplained symptoms (MUS) remains unclear, healthcare providers often struggle with these patients, especially with a different ethnic and/or cultural background. These challenges are insufficiently addressed in their training and in the organisation of care.

AIM

To improve healthcare provider-patient interaction focused on MUS patients in general and in ethnic minorities and refugees in particular through a systematic review of syndromal definitions and epidemiology and organisation of care of MUS patients.

METHODS

Screening of PubMed, Web of Science, Cinahl and Cochrane Library on the keywords 'Medical unexplained (physical) symptoms (MUPS)', 'Somatoform disorder', 'Functional syndrome', 'Diversity', 'Migrants', 'Ethnicity', 'Care models', 'Medical education', 'Communication skills', 'Health literacy'.

RESULTS

Different case definitions result in markedly different epidemiological estimates for MUS patients. Nevertheless, they are prevalent in a wide range of healthcare settings. Literature offers evidence of the effectiveness of structural frameworks in approaching MUS patients. Organisation of MUS care needs to transcend different levels of care: specialist tertiary and secondary care and primary care involving different qualifications of caregivers need to be aligned.

CONCLUSION

The systematic review identified significant gaps and shortcomings in organisation of care. These need to be addressed in order to improve outcomes.

Hormone therapy as a possible solution for postmenopausal women with nocturia: results of a pilot trial

OBJECTIVE

To observe the impact of different hormonal treatment options on nocturia, its causative factors and bother in postmenopausal women.

METHODS

This prospective study recruited 245 postmenopausal women and divided them into four treatment groups based on patient's choice: Estrogen + Progesterone (E+P), Estrogen-only in patients with a prior hysterectomy, tissue-selective estrogen complex (TSEC) and no treatment. Nocturia and its causative factors were observed using two standardized questionnaires before and after treatment: the International Consultation on Incontinence Questionnaire Nocturia Module and the Targeting the individual's Aetiology of Nocturia to Guide Outcomes (TANGO). The results of the Targeting the individual's Aetiology of Nocturia to Guide Outcomes were divided in four influencing topics of which the sum score was calculated.

RESULTS

A significant reduction in prevalence of nocturia ≥ twice per night was seen after treatment, as the prevalence decreased from 27.7% (59/213) to 16.4% (35/213). Specified per therapy, a significant reduction in nocturnal voiding frequency was observed in patients treated with E+P and TSEC (P = 0.018 and P = 0.018, respectively). This improvement could be explained by a significant reduction in SLEEP sum score in patients treated with E+P and TSEC (P < 0.001, P = 0.013, respectively). Estrogen-only led to a significant change in URINARY TRACT sum score, which is the result of a reduction in urgency prevalence (P = 0.039).

CONCLUSIONS

E+P and TSEC treatment led to a significant reduction in nocturia prevalence and bother in women with ≥ 2 nocturnal voids. This effect is mainly the result of improvement in sleep disorders, however an improvement in bladder disorders can be suggested as well. More research is necessary to confirm these findings.

Sociodemographic factors and strategies in colorectal cancer screening: a narrative review and practical recommendations

Background: Worldwide colorectal cancer is a frequently occurring cancer with a high disease burden. It is the second most frequent cancer in women and the third in men. The incidence of colorectal cancer is increasing because of ageing and unhealthy lifestyles.Aim: We aimed to perform a narrative literature review on methods and strategies for screening for colorectal cancer prior to colonoscopy.Design: Narrative literature review.Methods: The databases PubMed, Web of Science, Embase and The Cochrane Library were searched using keywords: 'colorectal cancer', '(mass) screening', 'occult blood', 'prevention', 'socioeconomic status', 'early diagnosis', 'Europe' and 'ethnicity'/'ethnic groups'.Results: 18 articles were included. Multiple randomised controlled trials have shown that screening programmes with faecal occult blood tests (FOBT), guaiac-FOBT (gFOBT) and immunochemical FOBT (iFOBT) represent a valid prevention strategy. Most studies favour iFOBT, because of ease to use, resulting in a higher uptake of screening, as well as a higher detection rate. A higher uptake is also achieved by mailing of the test. Overall the uptake of screening is higher in women, although more cancers are diagnosed in men. This can be explained by a lower sensitivity of FOBT in women. Furthermore, a strong correlation was found between a low socio-economic status and a low uptake of screening. The screening age lies between 50-74 years.Conclusion: Colorectal cancer is characterized by a significant incidence, morbidity and mortality. Systematic screening is effective for early detection. A non-selective test with iFOBT currently has the best validity with a higher sensitivity in men.

Retrospective Analysis of Risk Factors for Periodic Limb Movements in a Large Cohort of Insomnia and Chronic Fatigue Patients

Introduction Although the pathophysiology of periodic limb movements in sleep (PLMS) is not well understood, there is increasing belief that management of PLMS can modulate humans’ general health. The aim of this study is to investigate the associations between risk factors including the use of antidepressants, hypnotics, and antihistamines as well as of caffeine, alcohol, and nicotine and the occurrence of PLMS and periodic limb movement disorder (PLMD).

Methods Patients with either chronic fatigue or insomnia who underwent polysomnography as standardized clinical assessment were included in a retrospective study. Associations were calculated between substance use and sleep variables.

Results Tricyclic antidepressants and serotonin and norepinephrine reuptake inhibitor (SNRI) are significantly associated with higher rates of PLMS. Additionally, SNRI is significantly positive associated with PLMD, as also seen for selective serotonin reuptake inhibitors (SSRI). The most frequently used SSRI escitalopram was significantly positively associated with PLMS and PLMD. A significantly negative association was found between paroxetine and PLMS. Benzodiazepines are negatively associated with PLMS and PLMD. Sedative antidepressants, antihistamines, and substance use are not associated with PLMS nor PLMD in this study.

Discussion This retrospective study adds supportive evidence to the association of drug classes with PLMS and PLMD. These findings may impact on clinical management of patients with a combined anxiety or mood disorder in need for these drug classes on the one hand and a significant sleep architecture disturbance through PLMS, potentially contributing to daytime symptoms, on the other hand.

Opinion paper: the role of work in the management of medically unexplained physical symptoms

OBJECTIVES

Patients with medically unexplained physical symptoms suffer from chronic fatigue and/or pain in combination with a variety of other symptoms. A flexible, biopsychosocial approach is needed for diagnostic screening and global management. It is crucial to involve the direct patient environment, including family, friends, colleagues as well as health providers, evaluation, and reintegration sector. The aim of this paper is to review the importance of work in the management of medically unexplained physical symptoms.

METHODS

In this paper, different actors involved explain their views and handling concerning work in the management of MUPS.

RESULTS

Symptom severity and lack of understanding from the environment can negatively impact on earning an independent income from labor for years. Work, whether or not paid, is however, an important life domain with positive effects on physical, psychological, and social well-being. Therefore, health actors are pivotal in starting the professional reintegration process as soon as possible and should discuss this item from the early stage onward. Support services can be consulted in mutual interaction as required. A case manager, acting as a central intermediator within this multidisciplinary approach, may promote effective communication and coordination between the patients and their surrounding actors.

CONCLUSION

The professional reintegration process should start as soon as possible within the management of medically unexplained physical symptoms. As such, the care sector, the evaluation sector, and the professional integration sector should collaborate and effectively communicate with each other.

Patient perspectives on electronic health record accessibility and patient participation: a questionnaire survey

Objectives To explore patient perceptions on personal comfort with participation in their own care process and on support of this patient participation through electronic health record (EHR) accessibility. Methods Explorative quantitative questionnaire study in ambulatory patients visiting the departments of General Internal Medicine or Head, Neck and Maxillo-Facial Surgery of a Belgian tertiary referral center. Results Patients were recruited by convenience sampling of 438 out of the total of 1270 patients visiting either one of these departments within a time period of two weeks. Overall response rate was 97.3% (n = 426; 45.3% male; mean age 42.5 ± 15.4 years). Most patients (89.7%) indicated a desire to make healthcare decisions in partnership with their physician. They were in need of transparent and comprehensible health information. The EHR was perceived as a suitable and effective means to inform patients about their health and to increase involvement in care and treatment (77.6%). Furthermore, access to the EHR was perceived to result in a more effective communication transfer between physician and patient (65.5%), increased patient compliance (64.3%), and satisfaction (57.4%). Conclusion Patients indicate a desire for proactive participation in their individual care process. They felt that medical record accessibility could support decision-making and assist in managing and coordinating individual and personalized care choices.

Near-Infrared Spectroscopy Screening to Allow Detection of Pathogenic Mitochondrial DNA Variants in Individuals with Unexplained Abnormal Fatigue: A Preliminary Study

Unexplained abnormal fatigue is characterized by chronic fatigue persisting for at least six months and not sufficiently explained by any recognized medical condition. In this pilot study, twelve individuals with abnormal fatigue remaining unexplained after thorough screening were investigated using a near-infrared (NIR) spectroscopy handgrip test. Four of them were found to have an abnormal oxygen extraction pattern similar to participants with documented mitochondrial myopathy. In three of the four individuals, diverse mitochondrial abnormalities were documented by spectrophotometric, immunocytological, fluorescent, and morphological analyses performed in skeletal muscle and in cultured skin fibroblasts. Three of the four participants with decreased muscular oxygen extraction were each shown to harbor a different homoplasmic pathogenic mitochondrial DNA point mutation (m.961T > C, m.1555A > G, m.14484T > C). In the fourth participant, the presence of multiple large mitochondrial DNA deletions was suspected in muscle tissue. In contrast, none of the eight abnormally fatigued participants with normal NIR spectroscopy results harbored either a pathogenic mitochondrial DNA point mutation or large deletions ( P < 0.001). This pilot study shows that NIR spectroscopy may serve as a noninvasive screening tool to delineate a subgroup (of participants) with mitochondrial dysfunction among the large group of individuals with unexplained abnormal fatigue.

Basic psychological need experiences, fatigue, and sleep in individuals with unexplained chronic fatigue

Grounded in self-determination theory, this study tested the hypothesis that the satisfaction and frustration of the psychological needs for autonomy, competence, and relatedness would relate to fatigue and subjective and objective sleep parameters, with stress and negative sleep cognitions playing an explanatory role in these associations. During a stay at a sleep laboratory in Belgium, individuals with unexplained chronic fatigue (N = 160; 78% female) underwent polysomnography and completed a questionnaire at 3 different points in time (i.e., after arrival in the sleep lab, before bedtime, and the following morning) that assessed their need-based experiences and stress during the previous week, fatigue during the preceding day, and sleep-related cognitions and sleep during the previous night. Results indicated that need frustration related to higher stress, which in turn, related to higher evening fatigue. Need frustration also related to poorer subjective sleep quality and shorter sleep duration, as indicated by both subjective and objective shorter total sleep time and subjective (but not objective) longer sleep latency. These associations were accounted for by stress and negative sleep cognitions. These findings suggest that health care professionals working with individuals with unexplained chronic fatigue may consider focusing on basic psychological needs within their therapeutic approach.

Effects of continuous positive airway pressure on fatigue in two patients with obstructive sleep apnea presenting with chronic fatigue: case report and lessons learned from a failed trial

INTRODUCTION

Patients referred to tertiary care for multidisciplinary investigation of unexplained chronic fatigue are not seldom diagnosed with obstructive sleep apnoea (OSA). As standard treatment for OSA, continuous positive airway pressure (CPAP) has been shown to decrease daytime sleepiness in OSA patients. However, the effect on fatigue as major complaint in chronic fatigue patients without excessive daytime sleepiness, is not fully understood nor explored.

CASE REPORT

A prospective cross-over trial using effective and sham CPAP treatment periods in patients with unexplained chronic fatigue and OSA was interrupted because of poor recruitment and retainment due to complex design issues. We report the effect of CPAP after one month and one to two years follow-up on fatigue as primary outcome and on daytime sleepiness, global sleep quality and global mental and physical health as secondary outcomes in two patients completing the trial. In both patients, comparison of sequential effective and sham CPAP treatments failed to demonstrate consistent short-term effects in outcome measures, in spite of significant differences in apnoea-hypopnea index. However, substantial improvements of fatigue scores were observed at long-term follow-up in both individuals.

CONCLUSION

This is the first report of both short- and long-term effects of CPAP treatment on fatigue in patients with OSA and disabling chronic fatigue as primary complaint. A feasible prospective trial remains warranted in order to answer the question of CPAP responsiveness of fatigue in this patient population.

Intraorganizational Communication and Job Satisfaction Among Flemish Hospital Nurses: An Exploratory Multicenter Study

Intraorganizational communication affects job satisfaction and turnover. The goal of this study was to explore relationships between communication and job satisfaction, intention to leave, and burnout among Flemish hospital nurses. A multicenter questionnaire study was conducted in three hospitals using the Communication Satisfaction Questionnaire, the Turnover Intention subscale of the Questionnaire on the Experience and Evaluation of Work, and the Maslach Burnout Inventory. A visual analog scale measured job satisfaction. The mean job satisfaction score was 7.49/10 (±1.43). Almost 7% of nurse participants (93/1,355) reported a high intent to leave, and 2.9% of the respondents (41/1,454) had a score indicative of burnout. All dimensions of communication were associated with job satisfaction. A low score on any dimension of communication satisfaction, except “Relationship With Employees,” was associated with higher intent to leave and burnout. Study findings support the need for management interventions to enhance efficient communication and ensure high-quality care and patient safety.

The patient perspective on the effects of medical record accessibility: a systematic review

BACKGROUND

Health care is shifting from a paternalistic to a participatory model, with increasing patient involvement. Medical record accessibility to patients may contribute significantly to patient comanagement.

OBJECTIVES

To systematically review the literature on the patient perspective of effects of personal medical record accessibility on the individual patient, patient-physician relationship and quality of medical care.

METHODS

Screening of PubMed, Web of Science, Cinahl, and Cochrane Library on the keywords 'medical record', 'patient record', 'communication', 'patient participation', 'doctor-patient relationship', 'physician-patient relationship' between 1 January 2002 and 31 January 2016; systematic review after assessment for methodological quality.

RESULTS

Out of 557 papers screened, only 12 studies qualified for the systematic review. Only a minority of patients spontaneously request access to their medical file, in contrast to frequent awareness of this patient right and the fact that patients in general have a positive view on open visit notes. The majority of those who have actually consulted their file are positive about this experience. Access to personal files improves adequacy and efficiency of communication between physician and patient, in turn facilitating decision-making and self-management. Increased documentation through patient involvement and feedback on the medical file reduces medical errors, in turn increasing satisfaction and quality of care. Information improvement through personal medical file accessibility increased reassurance and a sense of involvement and responsibility.

CONCLUSION

From the patient perspective medical record accessibility contributes to co-management of personal health care.

How far to investigate presumed psychosomatic symptoms: Lessons from a particular case…

We describe a 43-year-old patient with subacute appearance of neurological and atypical complaints of anergia, anorexia and weight loss six months earlier. In spite of several admissions in different hospitals, no underlying somatic cause could be found and he was admitted to a psychiatric hospital with a tentative diagnosis of major depressive disorder. Subsequently, he was referred to the unit of medically unexplained physical symptoms within the department of general internal medicine for assessment by the psychiatrist, involved in this programme. Based on clinical suspicion and red flag symptoms such as involuntary weight loss, a broader internal medicine reassessment, including FDG whole-body PET-CT was requested. Neurological clinical exam showed minor deviations, but neither brain imaging nor a lumbar puncture were contributory. However, FDG PET-CT revealed abnormal moderately to intensely FDG positive lymph nodes in the retroperitoneum. Laparoscopic lymph node biopsy indicated germ cell tumour metastasis. Anti-NMDA antibody positivity allowed a diagnosis of paraneoplastic anti-NMDA encephalitis. Treatment of the underlying disease, a pure seminoma stadium II, consisting of orchidectomy and chemotherapy, resulted in a spectacular regression of 'psychosomatic' symptoms with long-term ability to return to work, and documented disappearance of the anti-NMDA antibody response.

Exploring the potential role of the advanced nurse practitioner within a care path for patients with chronic fatigue syndrome

AIMS

To explore the experiences and expectations of patients with chronic fatigue syndrome and general practitioners to develop the potential role of an advanced nurse practitioner at the diagnostic care path of abnormal fatigue developed for regional transmural implementation in the Belgian provinces of East and West Flanders.

BACKGROUND

Patients with chronic fatigue syndrome experience an incapacitating chronic fatigue that is present for at least 6 months. Since many uncertainties exist about the causes and progression of the disease, patients have to cope with disbelief and scepticism. Access to health care may be hampered, which could lead to inappropriate treatments and guidance.

DESIGN

Qualitative design.

METHODS

Individual semi-structured interviews were conducted with patients with chronic fatigue syndrome and general practitioners in Belgium. Data were collected over 9 months in 2014-2015. All interviews were audio recorded and transcribed for qualitative analysis using open explorative thematic coding.

RESULTS

Fifteen patients and 15 general practitioners were interviewed. Three themes were identified: mixed feelings with the diagnosis, lack of one central intermediator and insufficient coordination. Participants stressed the need for education, knowledge and an intermediator to provide relevant information at the right time and to build up a trust relationship.

CONCLUSION

This qualitative exploration underscores some clear deficiencies in the guidance of patients suffering from chronic fatigue syndrome and abnormal fatigue. An advanced nurse practitioner as a central intermediator in the transmural care of these patients could promote interdisciplinary/multidisciplinary collaboration and effective communication, provide education and ensure a structured and coordinated approach.

The role of basic psychological need satisfaction, sleep, and mindfulness in the health-related quality of life of people living with HIV

Research has not yet examined the relationship between psychological need satisfaction, sleep, mindfulness, and health-related quality of life in people living with HIV. This cross-sectional study ( N = 101; 84% male; mean age = 45.48, SD = 12.75) found need satisfaction to relate positively to physical and mental health. Sleep quality fully mediated the association with physical health and partially mediated the association with mental health. Furthermore, mindfulness related to higher sleep quality through higher need satisfaction. Findings underscore the role of need satisfaction in determining health-related quality of life and sleep quality in people living with HIV and suggest that mindfulness may facilitate need satisfaction.

Factors determining fatigue in the chronic fatigue syndrome: a path analysis

OBJECTIVES

To explore the interrelationship of different dimensions (fatigue, neuroticism, sleep quality, global mental and physical health) in patients with chronic fatigue syndrome (CFS).

METHODS

Patients meeting the Fukuda criteria of CFS filled out two independent fatigue scales (Fatigue Questionnaire, FQ and Checklist Individual Strength, CIS), NEO-Five Factor Inventory (NEO-FFI), Pittsburgh Sleep Quality Index (PSQI) and Medical Outcomes Study 36-item Short Form Health Survey (SF36). Exploratory and confirmatory path analyses were performed.

RESULTS

Out of 226 eligible patients, 167 subjects were included (mean age 39.13 years, SD 10.14, 92% female). In a first exploratory path analysis, using FQ for assessment of fatigue, night-time PSQI sleep quality had a direct effect on SF36 physical quality of life (PQoL) and no effect on FQ fatigue. This was confirmed by a subsequent path analysis with CIS fatigue and by confirmatory path analyses in 81 patients. These unexpected results raised the question whether FQ or CIS fatigue sufficiently operationalizes fatigue in CFS patients.

CONCLUSIONS

Poor sleep quality seems to directly impact on mental quality of life (MQoL) and PQoL without mediation of fatigue assessed with FQ and CIS. A more cohesive framework needs to be developed with more comprehensive clinical tools for the different dimensions in the construct of CFS.

A multidisciplinary network for the care of abnormal fatigue and chronic fatigue syndrome in the provinces of East and West Flanders in Belgium

The organization of care for patients with the chronic fatigue syndrome (CFS) in tertiary care referral centres from 2002 onwards, was negatively evaluated by the Belgian Health Care Knowledge Centre on the endpoint of socio-professional reintegration. Subsequently, the federal health authorities asked for the elaboration of a new and innovative model of stepped care, aiming at improved integration of diagnosis and treatment into primary care and between levels of health care for patients with CFS. The reference centre of the University Hospital Ghent took the initiative of recruiting partners in the Belgian provinces of East and West Flanders to guarantee the care for patients with medically unexplained symptoms, in particular abnormal fatigue and CFS. A new and innovative care model, in which general practitioners play a central role, emphasizes the importance of early recognition of the patient 'at risk', correct diagnosis and timely referral. Early detection and intervention is essential in order to avoid or minimize illness progression towards chronicity, to safeguard opportunities for significant health improvement as well as to enhance successful socio-professional reintegration. This approach covers both the large sample of patients developing somatic complaints without obvious disease in an early phase as well as the more limited group of patients with chronic illness, including CFS. Cognitive behavioural therapy and graded exposure/exercise therapy are the evidence based main components of therapy in the latter. A biopsychosocial model underlies the proposed path of care.

Determinants of adherence in a cohort of Belgian HIV patients: a pilot study

Since the era of highly active antiretroviral therapy (HAART), HIV is considered a chronic disease. Adherence to HAART is crucial for effectiveness. Non-adherence negatively impacts patient outcome and the larger economy. However, data on adherence among the Belgian HIV cohort are scarce. Therefore, the purpose of this pilot study was to identify determinants of adherence among HIV patients treated in Belgium. The study was conducted at the Aids Reference Centre of Ghent University Hospital between 1 January and 31 December 2012. Sociodemographic data were collected, along with the Simplified Medication Adherence Questionnaire (SMAQ), the Center for Adherence Support Evaluation (CASE) Adherence Index, the EuroQol-6D, the Medical Outcomes Study-HIV (MOS-HIV), the Beck Depression Inventory-II, and three neurocognitive complaints screening questions. To date, 218 patients participated in the study, among whom 173 (79·4%) were male. Mean age was 46·0±10·6 years and 133 patients (63·9%) were homosexual. According to the SMAQ and the CASE, 78·5% and 93·5% of the patients were adherent to antiretroviral therapy. Logistic regression analysis revealed that smoking, neurocognitive complaints, and female sex were independent determinants of non-adherence. In conclusion, there is an elevated risk for non-adherence in smokers, people experiencing neurocognitive problems, and women in our sample. The latter could reflect differences between male and female HIV patients in Belgium. Adherence improving initiatives should be tailored to these three risk groups.

Chordoid meningioma in an adult patient presenting with chronic fatigue and systemic inflammation

We report a 27-year-old woman presenting with chronic fatigue and depressive symptoms. Aspecific neurologic symptoms and biochemical indices of inflammation and anaemia triggered an MRI, revealing a tumor with compression of the medulla oblongata. After neurosurgical resection, anatomopathologic examination showed a chordoid meningioma. All complaints disappeared and inflammatory parameters normalized, suggesting an association with Castleman syndrome. This case demonstrates the importance of a systematic diagnostic approach in patients presenting with unexplained chronic fatigue.

Behavioural hyperventilation as a novel clinical condition associated with central sleep apnoea: a report of three cases

Central sleep apnoea (CSA) is a disorder characterised by repetitive episodes of decreased ventilation due to complete or partial reduction in the central neural outflow to the respiratory muscles. Hyperventilation plays a prime role in the pathogenesis of CSA. Chronic heart failure and dwelling at high altitude are classical conditions in which CSA is induced by hyperventilation. Hyperventilation syndrome (HVS) is a prevalent behavioural condition in which minute ventilation exceeds metabolic demands, resulting in haemodynamic and chemical changes that produce characteristic dysphoric symptoms. HVS is frequently caused by anxiety disorders and panic attacks. Until now, medical literature has focussed primarily on daytime symptoms of behavioural hyperventilation. It is currently unknown how this condition may affect sleep. Three cases are reported in which behavioural hyperventilation was associated with occurrence of significant central sleep apnoea, which was not present during normal tidal breathing in steady sleep. Therefore, behavioural hyperventilation should be added to the list of known clinical conditions associated with CSA.

Subjective sleep quality and daytime sleepiness in a large sample of patients with chronic fatigue syndrome (CFS)

Chronic fatigue syndrome (CFS) is characterised by incapacitating fatigue in combination with a number of minor criteria, including unrefreshing sleep without further specifications, in the absence of psychiatric and internal disease. As little data exist on subjective sleep quality and daytime sleepiness, these parameters were assessed in a large sample of CFS patients. Consecutive patients with a diagnosis of CFS in a tertiary referral centre filled out the Fatigue Questionnaire (FQ), Medical Outcomes Study 36-Item Short Form Health Survey (MOS SF-36), Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Inclusion comprised 415 individuals (mean age 40.5 yr, SD 7.9, range 18-64; 86% female). Mean FQ (26.90; SD 4.04), mean Global Physical Health from the MOS SF-36 (29.30; SD 12.25) and Global Mental Health from the MOS SF-36 (49.62; SD 18.31) scores corresponded with literature data for similar CFS samples. High mean ESS (10.51; SD 5.52) and global PSQI (10.17; SD 4.02) were observed. No significant relationship was found between ESS and global PSQI. In contrast, regression analysis demonstrated a significant cubic relation between ESS and 'PSQI without daytime dysfunction'. A subgroup (n=69) with an insomnia-like phenotype low ESS (<5), high PSQI (mean 11.51; SD 3.86) was observed. The assessment of subjective sleep quality and daytime sleepiness in a large sample of CFS patients indicated high mean PSQI and ESS values. ESS and 'PSQI without daytime dysfunction' were inversely related at the spectral ends of ESS. A distinct subgroup with clinical features of insomnia was identified.

Validation of the three-factor model of the PSQI in a large sample of chronic fatigue syndrome (CFS) patients

OBJECTIVE

To evaluate whether a 3-factor model of the Pittsburgh Sleep Quality Index (PSQI) scale would fit the constellation of sleep disturbances in patients with a diagnosis of chronic fatigue syndrome (CFS).

METHODS

Consecutive CFS patients filled out the PSQI. Scores from this self-report questionnaire were examined with exploratory and confirmatory factor analysis (CFA).

RESULTS

413 CFS patients were included for analysis in this study. CFA showed that the 7 PSQI component scores clustered into the 3 factors reported by Cole et al. (2006), i.e. Sleep Efficiency, Perceived Sleep Quality and Daily Disturbances. In contrast with the single-factor and all 2-factor models, all factor loadings were significant, and all goodness-of-fit values were acceptable.

CONCLUSION

In CFS, the PSQI operates as a 3-factor scoring model as initially seen in healthy and depressed older adults. The separation into 3 discrete factors suggests the limited usefulness of the global PSQI as a single factor for the assessment of subjective sleep quality, as also evidenced by a low Cronbach's alpha (0.64) in this patient sample.

Well-being in patients with chronic fatigue syndrome: the role of acceptance

OBJECTIVE

Research in chronic pain patients has shown that accepting the chronic nature of their illness is positively related to quality of life. The aim of this study was to investigate whether acceptance is also associated with better well-being in patients suffering from chronic fatigue syndrome (CFS).

METHODS

Ninety-seven patients completed a battery of questionnaires measuring fatigue, functional impairment, psychological distress, and acceptance.

RESULTS

Results indicated that acceptance has a positive effect upon fatigue and psychological aspects of well-being. More specifically, acceptance was related to more emotional stability and less psychological distress, beyond the effects of demographic variables, and fatigue severity.

CONCLUSION

We suggest that promoting acceptance in patients with CFS may often be more beneficial than trying to control largely uncontrollable symptoms.

The use of hypnosedative drugs in a university hospital setting

OBJECTIVE

The use of hypnosedatives (HSs) in the hospital and at home before admission was registered. Also, the incidence of HSs newly started in the hospital and the incidence of withdrawal in chronic users while in hospital was recorded.

METHODS

The study population consisted of 517 consecutively admitted patients recruited from 10 wards of the Ghent University Hospital; 493 of them received a questionnaire and were interviewed concerning the use of HSs at home and in the hospital, about the cause and duration of treatment, the type of HSs used, the presence and nature of any concomitant sleep or anxiety disorder. Main outcome measures were the actual use of HSs during hospitalisation as compared with the reported use, the influence of hospitalisation on use of HSs and the assessment of cause and duration of use of HSs.

RESULTS

Twenty-nine percent of the study sample took HSs at home and 45.2% while in the hospital. HSs were prescribed to 28.6% of the patients not habituated to chronic use of HSs at home. In contrast, 14.0% of the patients habituated to chronic use of HSs received no sleep medication while in hospital. Patients older than 60 years used more HSs than younger patients. Previous administration of HSs, sleep problems during hospital admission and female sex were predictive of HS-use. The main reason for prescription of HSs in the hospital was continuation of HSs taken at home. The most prescribed HSs were: lormetazepam, lorazepam, alprazolam, diazepam and zolpidem. Almost 10% of the patients were not informed on treatment with HSs. Among the subjects in whom HSs were newly started, 16.0% intended to continue this medication after discharge. Eleven percent took combinations of hypnosedative drugs.

CONCLUSIONS

The prevalence of prescription of HSs in the university hospital setting is high. Appropriate guidelines are needed to control the use of HSs during hospitalisation and to ensure withdrawal from these drugs upon discharge.

Chronic pain therapy: an evolution from solo-interventions to a holistic interdisciplinary patient approach

The treatment of chronic pain patients has changed over years. Anaesthesiologists treat pain patients, their skills in locoregional anaesthesia techniques and their pharmacological knowledge being a unique resource to reduce pain. However, the International Association for the Study of Pain provides more and more scientific evidence that chronic pain is a biopsychosocial event and that its diagnosis and treatment should be considered in a multidisciplinary frame. Nevertheless, in practice we can't deny the fact that there are several steps in the process in which the patient himself decides if he wants such an approach or not. The 'motivating' phase is a very important pretherapy and basic condition to start up a holistic pain treatment. Therefore, at the Ghent University Hospital Pain Clinic, we focused in a first step how to motivate our pain patients to take part in a multidisciplinary diagnostic examination, the second step is motivate them for an interdisciplinary treatment when it is indicated. We diagnose the four most important pain components: the sensory, myofacial, autonomic and psychosocial problems. The patient who is initially examined by the anaesthesiologist, will also be evaluated by the psychologist and the physician in rehabilitation medicine. By this way each component is mapped and a final (holistic) diagnosis can be made. In a weekly half-a-day meeting, the different specialists discuss the patients and put forward an interdisciplinary treatment plan. On several moments, the patients' treatment progress will be discussed and redirected if necessary. So, we hope to obtain an optimal result and avoid overtreatment and too invasive pain treatment.

Is there a rationale for prescription of benzodiazepines in the elderly? Review of the literature

Benzodiazepines (BZDs) constitute the most widely used symptomatic treatment of insomnia and anxiety. Many of these drugs are associated with adverse effects, such as daytime sedation and dependence with continued use. There is a concern about the rationale for and extent of benzodiazepine (BZD) use in the elderly. The sedation due to BZD use is a main risk factor for falls and other accidents. Impaired cognitive function with continuous use appears to be a major side effect. There is a general awareness that BZD use is inappropriate in many patients, and therefore discontinuation should be recommended whenever possible. Moreover, long-term use of these drugs should be actively discouraged. Although no unanimous recommendations concerning the optimal duration of the withdrawal process exist, BZDs may easily be withdrawn during a short period in most patients who are habituated to a low dose, if an initial phase with dose reduction and psychological support are provided. Alternative approaches involve sleep hygiene guidelines, behavioural treatment and psychotherapy tailored to the needs of the individual patient.

Chronic fatigue syndrome in the psychiatric practice

BACKGROUND

Chronic fatigue syndrome (CFS) is a complex syndrome with a psychiatric comorbidity of 70-80%. A psychiatric interview is necessary in order to exclude psychiatric illness and to identify psychiatric comorbidity. Studies have demonstrated that in general medical practice and in the non-psychiatric specialist practice, physicians tend to underdiagnose psychopathology in patients with CFS. There are many questions unanswered about the treatment of CFS Aim: Typical issues for the psychiatric practice are reviewed: psychiatric comorbidity, dysregulation of the PHA-axis and the treatment of CFS.

CONCLUSIONS

Depression, somatization, sleeping disorders and anxiety disorders are the most important psychopathological symptoms found in CFS patients. CFS should not be regarded as a masked (somatoform) depression. Although the results from neuroendocrinological studies assessing the hypothalamic-pituitary-adrenal axis (HPA-axis) are inconsistent, they suggest that there is a subgroup of CFS patients suffering from a discrete dysregulation of the HPA-axis resulting in basal hypocortisolaemia. These findings, however, do not reveal a causal relationship. Antidepressants do not seem to have a positive influence on the symptom of fatigue, but appear to be beneficial in alleviating the symptoms of depression and social functioning. Cognitive behaviour therapy and graded exercise show a significant improvement on fatigue and other symptoms and are the only treatments available for CFS patients.

Fast withdrawal from benzodiazepines in geriatric inpatients: a randomised double-blind, placebo-controlled trial

OBJECTIVE

We have previously demonstrated that temporary substitution with a low-dose hypnosedative drug may lead to successful withdrawal from chronic benzodiazepine (BZD) use in the majority of patients admitted to a geriatric ward. In the present study, a withdrawal programme was evaluated in which the habitual treatment with BZDs was replaced by either 1 mg lormetazepam or placebo, defining withdrawal success rate, sleep quality and withdrawal symptoms as main outcomes.

METHODS

The target population was geriatric inpatients who had been taking BZDs for at least 3 months. Subjects suffering from mental disorders were excluded. Lormetazepam or placebo were randomly assigned and given in a double-blind fashion. After 1 week, the replacement therapy was discontinued. Subjective estimations of sleep quality and withdrawal symptoms were registered at predefined intervals, four times in a period of 30 days, using standard questionnaires (the Pittsburgh Sleep Quality Index and the Benzodiazepine Withdrawal Symptom Questionnaire, respectively).

RESULTS

The success rate was significantly higher in the lormetazepam substitution group (80% vs 50% in the placebo group, P < 0.05). Both the subjective quality of sleep and withdrawal symptoms were significantly better in the lormetazepam substitution group. Important withdrawal effects were observed in the control group in two patients with a history of chronic alcohol abuse.

CONCLUSIONS

Initial replacement therapy with a low-dose BZD is preferred over placebo, since the latter alternative is associated with worse sleep quality and a lower success rate. Placebo must only be used under medical scrutiny, given the potential for unmasking delirious symptoms, especially in patients with concomitant alcoholism.

A programme for short-term withdrawal from benzodiazepines in geriatric hospital inpatients: success rate and effect on subjective sleep quality

OBJECTIVE

We tested the hypothesis that a short-term programme for withdrawal of benzodiazepines (BZD) is feasible in hospitalized geriatric patients.

METHODS

Fifty-six geriatric subjects who had been taking BZD for at least 3 months were asked to discontinue these drugs upon admission to the inpatient ward. A withdrawal programme including initial substitution therapy combined with psychological consulting was offered. The usual BZD medication was replaced by either lormetazepam 1 mg or trazodone 50 mg, administered at bedtime. After 1 week of replacement therapy all sedative medication was stopped. The subjective estimations of sleep quality were evaluated four times during a period of 6 weeks.

RESULTS

Forty-nine patients agreed to participate. In this group four subjects (8.2%) resumed BZD use while in the hospital and another seven subjects (14.3%) relapsed after discharge. Therefore, the overall success rate was 77.6% in the group of volunteers and 67. 9% in the total group of eligible patients. The data of the present study further demonstrate that no major withdrawal symptoms occurred and that the subjective quality of sleep remained virtually unchanged in the course of the programme. The sleep quality was not significantly different in patients on trazodone versus patients on lormetazepam. The success rate was similar in both drug substitution groups.

CONCLUSIONS

Short-term withdrawal of BZD may be achieved in two-thirds of elderly hospital inpatients without deterioration of sleep quality or other deleterious side-effects.
