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.

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.

Longitudinal assessment of sleep and fatigue according to baby feeding method in postpartum women: a prospective observational study.

BACKGROUND: Poor subjective sleep quality, depressive symptoms and fatigue occur frequently in postpartum. However, the dynamics of their respective associations from prepartum throughout the maternity period in function of baby feeding method have not been fully elucidated. METHODS: Prospective, longitudinal study using validated questionnaires probing for sleep quality, insomnia, fatigue and depressive symptoms at 35-37 weeks of gestation and at 2, 8 and 12 weeks postpartum in the obstetric departments of two Flemish hospitals. Somers'd ordinal correlation was used for correlations between the results of questionnaires (ratio variables) and the feeding method variable (an ordinal variable); T tests (normal data) or Mann Whitney (non normal data) tests for equality of means; ordinal regression ('Proportional odds model') to investigate the predictive value of parameters at one moment on the feeding method choice at a later moment; logistic regression to investigate the predictive value of parameters on later change of feeding method. RESULTS: 188 women indicating a choice for either bottle or breastfeeding in prepartum (27-35 weeks' gestation) were included. Higher fatigue assessed through the Fatigue Severity Scale within late pregnancy was moderately associated with primary bottle feeding choice. Fatigue decreased at early and late postpartum in bottle feeding (-0.38 ± 1.04; p = .110 and - 0.31 ± 1.01; p = .642 respectively), but remained unchanged from late pregnancy through early and late postpartum in breastfeeding (0.04 ± 1.21; p = .110 and - 0.27 ± 0.96; p = .642 respectively), resulting in similar fatigue in both feeding methods in early through late postpartum. There were no differences in sleep quality or insomnia symptoms at all time points. Presence of postpartum depressive symptoms were associated with early switching to bottle feeding (Somers' d correlation 0.11 (p = .021). CONCLUSIONS: Fatigue and depressive symptoms are inversely associated with breastfeeding initiation or maintenance and influence feeding method dynamics.

Medical educators' experiences on medically unexplained symptoms and intercultural communication-an expert focus group study.

BACKGROUND: Medically unexplained symptoms (MUS) are highly prevalent and remain challenging in healthcare and medical education, along with the increase in the importance of intercultural issues regarding MUS. However, less is known about the challenges of professionally addressing patients with MUS in the interprofessional and intercultural contexts. Thus, the present study aims to provide the first exploration of the experiences of medical specialists regarding treating MUS in intercultural contexts and inputs for training development on the intercultural aspects of MUS. METHODS: Three focus groups (total n = 13) consisting of medical specialists from a Hungarian university who were teaching at the medical faculty in intercultural settings and also worked for the university health services were interviewed. The topics covered the participants' personal experiences on addressing MUS and the challenges of intercultural communication and the intercultural educational context. Thematic analysis was used to yield a qualitative account of the interviews as guided by the research questions. RESULTS: Representing the different aspects of medical specialists, the study identified three main themes in the experiences of medical specialists, namely, 1) the need to adapt to the personal world of patients and search for common frames to understand MUS, 2) the need to discover methods for adapting to cultural differences and 3) the need to enhance the interprofessional coordination of knowledge and practices. CONCLUSIONS: The results are in line with the distinct conclusions of previous studies. Moreover, an integrated educational program on the intercultural aspects of MUS may address the main themes separately and, subsequently, support their integration. Therefore, the study discusses the manner in which an integrated educational program on the intercultural aspects of MUS may address the needs recognized in these aspects.

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.

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.

Upper respiratory tract symptoms and salivary immunoglobulin A of elite female gymnasts: a full year longitudinal field study.

The aim of this study was to determine the frequency of upper respiratory tract symptoms (URS) in elite female gymnasts during a training season. In addition, we aimed to observe the extent to which salivary immunoglobulin A (sIgA) is associated with URS in these athletes, including potential effects of the season and timing of sample collection. Over one year, 18 elite female gymnasts completed URS and fatigue questionnaires weekly and provided 1 mL of saliva after a minimum 36 h of rest (morning or afternoon) to measure relative sIgA concentration (= mean absolute sIgA value of the week divided by the mean absolute sIgA value of the weeks without URS). Mean weekly URS and mean relative sIgA values per gymnast correlated negatively (r = -0.606, P = 0.022). Most URS were noted in the most fatigued gymnasts (7.4 ± 10.1 vs. 2.5 ± 5.6 (P < 0.001) for 'normal' and 2.1 ± 3.7 (P = 0.001) for 'better than normal' rested). In spring, relative sIgA was higher compared to autumn (112 ± 55 vs. 89 ± 41%, P < 0.001) and winter (92 ± 35%, P = 0.001), while during summer, relative sIgA appeared higher compared to autumn (110 ± 55 vs. 89 ± 41%, P = 0.016). The interaction effect with timing of sample collection showed higher relative sIgA values in morning samples in spring and summer compared to afternoon samples, with the inverse observed in autumn and winter (F = 3.565, P = 0.014). During a gymnastics season, lower relative sIgA values were linked to higher susceptibility to URS in elite gymnasts. However, relative sIgA values were influenced by season and timing of sample collection and thus should be considered when interpreting sIgA data.

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.

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.

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.

Slow Wave Sleep of Elite and Nonelite Gymnasts Is Influenced by Weekly Training Hours, Not by Fitness Level.

PURPOSE: This study aimed to determine the influencing factors of potential differences in sleep architecture between elite (EG) and nonelite (NEG) female artistic gymnasts. METHODS: Twelve EG (15.1 [1.5] y old) and 10 NEG (15.3 [1.8] y old) underwent a nocturnal polysomnography after a regular training day (5.8 [0.8] h vs 2.6 [0.7] h), and, on a separate test day, they performed an incremental treadmill test after a rest day in order to determine physical fitness status. A multiple linear regression assessed the predictive value of training and fitness parameters toward the different sleep phases. Total sleep time and sleep efficiency (proportion of time effectively asleep to time in bed), as well as percentage of nonrapid eye movement sleep phase 1 (NREM1) and 2 (NREM2), slow wave sleep (SWS), and rapid eye movement sleep (REM), during a single night were compared between EG and NEG using an independent-samples t test. RESULTS: Peak oxygen uptake influenced NREM1 (ß = 1.035, P = .033), while amount of weekly training hours predicted SWS (ß = 1.897, P = .032). No differences were documented between EG and NEG in total sleep time and sleep efficiency. SWS was higher in EG (36.9% [11.4%]) compared with NEG (25.9% [8.3%], P = .020), compensated by a lower proportion of NREM2 (38.7% [10.2%] vs 48.4% [6.5%], P = .017), without differences in NREM1 and REM. CONCLUSIONS: The proportion of SWS was only predicted by weekly training hours and not by training hours the day of the polysomnography or physical fitness, while NREM1 was linked with fitness level. Sleep efficiency did not differ between EG and NEG, but in EG, more SWS and less NREM2 were identified.

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.

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.

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.

Medically unexplained physical symptoms in patients visiting the emergency department: an international multicentre retrospective study.

OBJECTIVE: The objective of this study was to assess the incidence and characteristics of patients presenting with physical symptoms that remain medically unexplained at the emergency department (ED). PATIENTS AND METHODS: A retrospective chart study was carried out in three hospitals in The Netherlands and Belgium. All patients (age > 18 years) visiting the ED in 4 selected weeks in 2013 at the Erasmus University Medical Center (Erasmus MC) in Rotterdam, The Netherlands, and 1 selected week in 2013 at the Haaglanden Medical Center, Westeinde HMC in The Hague, The Netherlands, and the University Hospital Ghent (UZG), Belgium, were included. Descriptive statistics were used for data analysis. RESULTS: A total of 2869 patients (Erasmus MC 1674, HMC 691, UZG 504) were included. Medically unexplained physical symptoms in the emergency department (EDMUPS) were present in 13.4% of all ED visits (Erasmus MC 12.5%, HMC 18.7%, UZG 9.1%). No EDMUPS were identified in trauma patients. When excluding trauma patients, EDMUPS were present in 18.5% (Erasmus MC 16.8%, HMC 26.5%, UZG 13.3%) of the visits. The characteristics of patients with and without EDMUPS differed significantly; patients with EDMUPS were more often younger, female, self-referred, frequent visitors, were prescribed less medication and more often had a psychiatric disease. Dutch and Belgian Hospital differed in the distribution of patients in triage categories and in the incidence of psychiatric illnesses. CONCLUSION: Physical symptoms remain unexplained in a significant number of patients at the time of ED assessment.

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.

Reciprocal associations between daily need-based experiences, energy, and sleep in chronic fatigue syndrome.

OBJECTIVE: Previous findings indicate that patients with chronic fatigue syndrome (CFS) report significant day-to-day fluctuations in subjective energy and sleep. Herein, we examined whether daily variation in the satisfaction and frustration of the basic psychological needs for autonomy, competence, and relatedness would contribute to daily variation in subjective energy and quality and quantity of sleep. In addition, we examined whether daily variation in sleep would contribute to daily need-based experiences through (i.e., mediated by) daily fluctuations in subjective energy. METHOD: CFS patients (N = 120; 92% female; Mage = 42.10 years, SD = 10.46) completed a diary for 14 days which assessed their need-based experiences and subjective energy every evening and sleep every morning. RESULTS: Results indicated that subjective energy, sleep, and need experiences fluctuated significantly from day to day. Daily need satisfaction related to less daily fatigue and more daily vitality, while the opposite pattern was observed for daily need frustration. Daily need frustration was also uniquely related to poorer daily sleep quality. Lastly, better daily sleep quality was also uniquely related to more daily need satisfaction and less daily need frustration via (i.e., mediated by) daily variation in subjective energy. These reciprocal within-day associations remained significant after controlling for the previous day's level of each outcome, with the exception of the relation between need frustration and sleep quality. CONCLUSION: The present findings underscore the reciprocal day-to-day association between need-based experiences and subjective energy in CFS.

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.
