RESUMO
BACKGROUND: Severe fatigue following coronavirus disease 2019 (COVID-19) is prevalent and debilitating. This study investigated the efficacy of cognitive-behavioral therapy (CBT) for severe fatigue following COVID-19. METHODS: A multicenter, 2-arm randomized controlled trial was conducted in the Netherlands with patients being severely fatigued 3-12 months following COVID-19. Patients (N = 114) were randomly assigned (1:1) to CBT or care as usual (CAU). CBT, targeting perpetuating factors of fatigue, was provided for 17 weeks. The primary outcome was the overall mean difference between CBT and CAU on the fatigue severity subscale of the Checklist Individual Strength, directly post-CBT or CAU (T1), and after 6 months (T2). Secondary outcomes were differences in proportions of patients meeting criteria for severe and/or chronic fatigue, differences in physical and social functioning, somatic symptoms, and problems concentrating between CBT and CAU. RESULTS: Patients were mainly nonhospitalized and self-referred. Patients who received CBT were significantly less severely fatigued across follow-up assessments than patients receiving CAU (-8.8 [95% confidence interval {CI}, -11.9 to -5.8]); P < .001), representing a medium Cohen's d effect size (0.69). The between-group difference in fatigue severity was present at T1 (-9.3 [95% CI, -13.3 to -5.3]) and T2 (-8.4 [95% CI, -13.1 to -3.7]). All secondary outcomes favored CBT. Eight adverse events were recorded during CBT, and 20 during CAU. No serious adverse events were recorded. CONCLUSIONS: Among patients, who were mainly nonhospitalized and self-referred, CBT was effective in reducing fatigue. The positive effect was sustained at 6-month follow-up. CLINICAL TRIALS REGISTRATION: Netherlands Trial Register NL8947.

PURPOSE: Insight into emotional distress of cancer survivors from ethnic minority groups in Europe is scarce. We aimed to compare distress levels of survivors from ethnic minorities to that of the majority population, determine whether the association between having cancer (yes vs. no) and distress differs among ethnic groups and investigate sociocultural correlates of distress. METHODS: Cross-sectional data were derived from HELIUS, a multi-ethnic cohort study conducted in the Netherlands. Of 19,147 participants, 351 were diagnosed with cancer (n = 130 Dutch, n = 75 African Surinamese, n = 53 South-Asian Surinamese, n = 43 Moroccan, n = 28 Turkish, n = 22 Ghanaian). Distress (PHQ-9, MCS-12) and correlates were assessed by self-report. Cancer-related variables were derived from the Netherlands Cancer Registry. RESULTS: Survivors were on average 7 years post-diagnosis. Survivors from South-Asian Surinamese, Moroccan, Turkish and Ghanaian origin reported more distress than survivors from Dutch origin (effect sizerange : 0.44-1.17; adjusted models). The association between having cancer or not with distress differed in direction between Dutch and the non-Dutch ethnic groups: Non-Dutch cancer patients tended to have more distress than their cancer-free peers, whereas Dutch cancer patients tended to have less distress than their cancer-free peers. For Moroccan and Turkish patients, the acculturation style of separation/marginalization, compared to integration/assimilation, was associated with higher depressive symptoms. In analyses pooling data from all ethnic minorities, lower health literacy, lower emotional support satisfaction and younger age at the time of migration were associated with higher depressive symptoms. Lower health literacy, fewer emotional support transactions, and more frequent attendance at religious services were associated with worse mental health. CONCLUSION: Cancer survivors from ethnic minorities experience more distress than those from the majority population. Culturally sensitive supportive care should be considered.

BACKGROUND: Cognitive behavioral therapy (CBT) is an evidence-based intervention for severe fatigue. Changes in patients' fatigue scores following CBT might reflect not only the intended relief in fatigue but also response shift, a change in the meaning of patients' self-evaluation. Objectives were to (1) identify the occurrence of response shift in patients undergoing CBT, (2) determine the impact of response shift on the intervention effect, and (3) investigate whether changes in fatigue-related cognitions and perceptions, targeted during CBT, are associated with response shift. METHODS: Data of three randomized controlled trials testing the efficacy of CBT in individuals with chronic fatigue syndrome (CFS, n = 222), cancer (n = 123), and diabetes (n = 107) were re-analyzed. Fatigue severity was measured with 8 items from the Checklist Individual Strength, a valid and widely used self-report questionnaire. Structural equation modelling was applied to assess lack of longitudinal measurement invariance, as indication of response shift. RESULTS: As expected, in all three trials, response shift was indicated in the CBT groups, not the control groups. Response shift through reprioritization was indicated for the items "Physically, I feel exhausted" (CFS) and "I tire easily" (cancer, diabetes), which became less vs. more important to the measurement of fatigue, respectively. However, this did not affect the intervention effects. Some changes in cognitions and perceptions were associated with the response shifts. CONCLUSIONS: CBT seems to induce response shift through reprioritization across patient groups, but its occurrence does not affect the intervention effect. Future research should corroborate these findings and investigate whether patients indeed change their understanding of fatigue.

OBJECTIVES: To evaluate the feasibility, usability and clinical value of daily diary assessments combined with actigraphy in older persons with cognitive impairment. METHODS: For 63 days, patients ≥60 years with cognitive impairments filled out a daily diary (including standardized questionnaires and cognitive test battery), and wore an actiwatch (sleep). After the study, participants and clinicians received personal feedback about patterns and daily triggers of depressive symptoms, sleep and cognitive performance. We assessed feasibility (participation rate, compliance and subjective burden), usability (variability and floor- or ceiling effects) and clinical value for patients and their clinicians (questionnaires). RESULTS: Of 96 eligible patients, 13 agreed to participate (13.5%). One patient dropped out after 2 days, another after 37 days, and another did not complete the cognitive test battery. Compliance rate was high (6.7-10% missing values). Subjective burden was relatively low. Time-series data showed sufficient variability and no floor- or ceiling effects, except for one relevant ceiling effect on the One Back task. The personal feedback report was considered insightful by 4 out of 11 participants and 5 out of 7 clinicians. CONCLUSION: Daily assessments are suitable for a minority of cognitively impaired older persons, but is helpful to increase insight into their symptoms.
RESUMO
INTRODUCTION: Failure to incorporate key patient-reported outcome (PRO) content in trial protocols affects the quality and interpretability of the collected data, contributing to research waste. Our group developed evidence-based training specifically addressing PRO components of protocols. We aimed to assess whether 2-day educational workshops improved the PRO completeness of protocols against consensus-based minimum standards provided in the SPIRIT-PRO Extension in 2018. METHOD: Annual workshops were conducted 2011-2017. Participants were investigators/trialists from cancer clinical trials groups. Although developed before 2018, workshops covered 15/16 SPIRIT-PRO items. Participant feedback immediately post-workshop and, retrospectively, in November 2017 was summarised descriptively. Protocols were evaluated against SPIRIT-PRO by two independent raters for workshop protocols (developed post-workshop by participants) and control protocols (contemporaneous non-workshop protocols). SPIRIT-PRO items were assessed for completeness (0 = not addressed, 10 = fully addressed). Mann-Whitney U tests assessed whether workshop protocols scored higher than controls by item and overall. RESULTS: Participants (n = 107) evaluated the workshop positively. In 2017, 16/41 survey responders (39%) reported never applying in practice; barriers included role restrictions (14/41, 34%) and lack of time (5/41, 12%). SPIRIT-PRO overall scores did not differ between workshop (n = 13, median = 3.81/10, interquartile range = 3.24) and control protocols (n = 9, 3.51/10 (2.14)), (p = 0.35). Workshop protocols scored higher than controls on two items: 'specify PRO concepts/domains' (p = 0.05); 'methods for handling missing data' (p = 0.044). CONCLUSION: Although participants were highly satisfied with these workshops, the completeness of PRO protocol content generally did not improve. Additional knowledge translation efforts are needed to assist protocol writers address SPIRIT-PRO guidance and avoid research waste that may eventuate from sub-optimal PRO protocol content.

OBJECTIVE: Fatigue is a common symptom among cancer survivors that can be successfully treated with cognitive-behavioral therapy (CBT). Insights into the working mechanisms of CBT are currently limited. The aim of this study was to investigate whether improvements in targeted cognitive-behavioral variables and reduced depressive symptoms mediate the fatigue-reducing effect of CBT. METHODS: We pooled data from three randomized controlled trials that tested the efficacy of CBT to reduce severe fatigue. In all three trials, fatigue severity (checklist individual strength) decreased significantly following CBT. Assessments were conducted pre-treatment and 6 months later. Classical mediation analysis testing a pre-specified model was conducted and its results compared to those of causal discovery, an explorative data-driven approach testing all possible causal associations and retaining the most likely model. RESULTS: Data from 250 cancer survivors (n = 129 CBT, n = 121 waitlist) were analyzed. Classical mediation analysis suggests that increased self-efficacy and decreased fatigue catastrophizing, focusing on symptoms, perceived problems with activity and depressive symptoms mediate the reduction of fatigue brought by CBT. Conversely, causal discovery and post-hoc analyses indicate that fatigue acts as mediator, not outcome, of changes in cognitions, sleep disturbance and depressive symptoms. CONCLUSIONS: Cognitions, sleep disturbance and depressive symptoms improve during CBT. When assessed pre- and post-treatment, fatigue acts as a mediator, not outcome, of these improvements. It seems likely that the working mechanism of CBT is not a one-way causal effect but a dynamic reciprocal process. Trials integrating intermittent assessments are needed to shed light on these mechanisms and inform optimization of CBT.

INTRODUCTION: Fear of cancer progression (FCP) impacts quality of life and is a prevalent unmet need in patients diagnosed with advanced cancer, particularly as treatment options are reduced. We aimed to identify longitudinal patterns in FCP over 6 months in patients with advanced cancer receiving comprehensive tumour genomic profiling (CTGP) results, and their correlates. METHODS: Patients with pathologically confirmed metastatic disease (â¼70% rare cancers) receiving or post their last line of standard therapy completed questionnaires at T0 (prior to CTGP), T1 (immediately post CTGP results) and T2 (2 months later). RESULTS: High stable (N = 52; 7.3%) and low/moderate stable (N = 56; 7.8%) FCP patterns over time typified the largest participant groups (N = 721). Those with an immediately actionable variant versus a non-actionable variant (p = 0.045), with higher FCP (p < 0.001), and lower Functional Assessment of Chronic Illness Therapy-Spiritual Well-being (FACIT-Sp) scores (p = 0.006) at T0, had higher FCP at T1. Those with higher FCP at T0 (p < 0.001) and at T1 (p < 0.001), lower FACIT-Sp scores at T1 (p = 0.001), lower education (p = 0.031) and female gender (p = 0.027) had higher FCP at T2. DISCUSSION: Routine screening for psychological/spiritual characteristics in those about to undergo CTGP may help to identify patients who may benefit from closer monitoring and provision of psychosocial support. Future studies should explore interventions to best address FCP in this vulnerable group, as interventions assessed to date have almost all addressed patients with curative cancers or newly diagnosed advanced disease.

OBJECTIVES: To develop a cancer-specific multi-attribute utility instrument derived from the Functional Assessment of Cancer Therapy - General (FACT-G) health-related quality of life (HRQL) questionnaire. METHODS: We derived a descriptive system based on a subset of the 27-item FACT-G. Item selection was informed by psychometric analyses of existing FACT-G data (n = 6912) and by patient input (n = 82). We then conducted an online valuation survey, with participants recruited via an Australian general population online panel. A discrete choice experiment (DCE) was used, with attributes being the HRQL dimensions of the descriptive system and survival duration, and 16 choice-pairs per participant. Utility decrements were estimated with conditional logit and mixed logit modeling. RESULTS: Eight HRQL dimensions were included in the descriptive system: pain, fatigue, nausea, sleep, work, social support, sadness, and future health worry; each with 5 levels. Of 1737 panel members who accessed the valuation survey, 1644 (95%) completed 1 or more DCE choice-pairs and were included in analyses. Utility decrements were generally monotonic; within each dimension, poorer HRQL levels generally had larger utility decrements. The largest utility decrements were for the highest levels of pain (-0.40) and nausea (-0.28). The worst health state had a utility of -0.54, considerably worse than dead. CONCLUSIONS: A descriptive system and preference-based scoring approach were developed for the FACT-8D, a new cancer-specific multi-attribute utility instrument derived from the FACT-G. The Australian value set is the first of a series of country-specific value sets planned that can facilitate cost-utility analyses based on items from the FACT-G and related FACIT questionnaires containing FACT-G items.

OBJECTIVE: Fatigue is a distressing symptom many cancer patients experience even after completion of treatment. Although theory and empirical evidence indicate that negative cognitions perpetuate fatigue after completion of treatment, insight into how this process unfolds in daily life is limited. This study used an intensive longitudinal design to investigate the reciprocal relationship between catastrophizing and fatigue in daily life and whether affective and behavioral processes mediate these relationships. METHODS: Post-treatment colorectal cancer patients (n = 101) completed daily diaries (14 days, 3 times daily) regarding their fatigue, catastrophizing, positive and negative affect, and physical activity. Multilevel modeling was applied to investigate within-person associations within days. RESULTS: Analyses revealed a positive reciprocal relationship between fatigue and catastrophizing throughout the day. That is, high levels of catastrophizing were associated with increases in fatigue within patients. In turn, but to a lesser extent, high levels of fatigue predicted increases in catastrophizing at the next assessment. Low positive affect and high negative affect mediated the effect of catastrophizing on increases in fatigue. Only negative affect mediated the reverse relationship. Physical activity did not mediate either relationship. CONCLUSIONS: This study provides evidence for a mutually reinforcing relationship between catastrophizing and fatigue in daily life, which might explain the perpetuation of fatigue after completion of cancer treatment. Fatigue-specific cognitive behavior therapy could be improved by educating patients about this daily reciprocal relationship, train them to quickly replace catastrophizing thoughts in daily life, and help them to cope with affective changes induced by fatigue.

The growth of the human brain during the embryonic period was assessed in terms of longitudinal measurements in staged embryos. Precise graphic reconstructions prepared by the onerous point-plotting method were considered to be the most reliable, and 23 were examined in detail. A distinction is necessary between measurements of the brain (cerebral diameters) and those of the skull (osseous diameters), and also between those of the folded brain in situ, studied here, and the later relatively straightened brain. Longitudinal measurements were made of individual neuromeres and their successors in steps (neuromeric lengths). The sum of the neuromeric measurements at any given stage provides the total neuromeric length (TNL) of the folded brain in situ at that stage and it increases in keeping with the greatest length (GL) of the embryo. At stages 16-19, however, the neuromeric length of the brain may exceed the GL. From stage 20 onwards the body length increases more rapidly compared with the length of the brain. The most cephalic neuromere is the telencephalon medium, abbreviated T1 here. The cerebral hemispheres are derived from it, although they are not neuromeres. The hemispheres soon extend rostrally beyond the limit of T1 by an amount that is here designated T2, and that indicates the growth of the telencephalon rostral to the commissural plate, which is the site of the future corpus callosum. Further laterally, the hemispheric length (future fronto-occipital diameter) increases rapidly, as does also the bitemporal (biparietal) diameter. At the end of the embryonic period these diameters are one fourth to one fifth of the head circumference. Additional neuromeric information becomes manifest when the measurements are calculated as percentages of the total length of the brain. The rhombencephalon decreases considerably, diencephalon 2 increases greatly, whereas diencephalon 1 diminishes, and the cerebral hemispheres enlarge massively. In addition, specific neuromeres or subdivisions come to occupy relatively more or relatively less of the total. Three periods were found during which individual neuromeres acquire their maximal or minimal lengths: the maximal absolute lengths were in period 3, whereas the maximal and minimal percentage lengths were in periods 1 and 3. The various neuromeric changes are considered to be related to alterations in functional development. Finally, in furtherance of establishing continuity in prenatal data, comparisons were effected between embryonic and fetal measurements.

BACKGROUND: Chronic fatigue is a common symptom among patients who have been treated for cancer. Current psychosocial interventions typically target the patient alone, despite growing evidence suggesting that a couples' approach can increase and broaden the efficacy of an intervention. Therefore, based on an existing web-based mindfulness-based cognitive therapy for patients, the couple intervention COMPANION was developed. OBJECTIVE: The primary objectives of this study are to determine the acceptability of COMPANION and its potential efficacy in reducing fatigue in patients with cancer. Our secondary objectives are to examine the feasibility of the trial procedures and the potential working mechanisms of the couple intervention. METHODS: We will conduct a single-arm pilot trial for couples (ie, patients with cancer with chronic fatigue and their partners). All couples are allocated to the web-based couple intervention that consists of psychoeducation, mindfulness, and cognitive-behavioral exercises. The 9 sessions of the intervention are supervised remotely by a trained therapist. Patients and partners will complete questionnaires before starting the intervention (T0), 2 weeks after completing the intervention (T1), and 1 month after T1 (T2). They will also fill out weekly diaries during the intervention period. A subsample of patients (n≈5) and partners (n≈5) as well as all the therapists providing COMPANION will participate in the final focus groups. Benchmark values have been defined to determine the acceptability (ie, ≥60% of couples complete the intervention and/or ≥70% of the participants are satisfied with the intervention) and potential efficacy (ie, a significant improvement in fatigue and/or a clinically relevant improvement in fatigue in 45% of the patients between T0 and T1) of the intervention. The trial procedures are deemed feasible if an average of at least three couples are included per recruiting month and/or adherence to the assessments is at least 65% for T1 and the diaries and 60% for T2. To establish potential working mechanisms, changes in affect, sleep, catastrophizing, partner communication and interactions, self-efficacy, mindfulness, and closeness will be examined. Quantitative outcomes will be interpreted along with the results from the focus groups. RESULTS: Data collection is expected to be completed by March 2024. CONCLUSIONS: This pilot trial will test the first web-based mindfulness-based cognitive therapy for couples targeting chronic cancer-related fatigue. Findings will indicate whether proceeding with a randomized controlled trial is warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT05636696; https://clinicaltrials.gov/study/NCT05636696.

RESUMO
The initial development of the cranial nerves was studied in 245 human embryos of stages 10-23 (4-8 postfertilizational weeks). Significant findings in the human embryo include the following. (1) Neuronal migration is a characteristic feature in the development of all the cranial nerves at stages 13-18, with the exception of the somatic efferent group. (2) The somatic efferent and the visceral efferent neurons are arranged respectively in ventrolateral and ventromedial columns (stages 13-17). (3) The ventrolateral column gives rise to somatic efferent nuclei; the neurons of the hypoglossal nerve develop rapidly and show a segmental organization as four roots that innervate three of the four occipital somites (stage 13); the abducent nucleus becomes displaced rostrally by a change in the rhombomeric pattern at stage 16. (4) The ventromedial column, originally continuous in rhombomeres 2-7, gives rise to visceral efferent and pharyngeal efferent nuclei. (5) All the 'true' cranial nerves (III-XII) are recognizable by stage 16. (6) In a primary migration the visceral efferent neurons proceed mediolaterally and accumulate dorsolaterally as nuclei (stages 13, 14); they differentiate into salivatory nuclei (stages 16, 17). (7) A secondary migration involves the pharyngeal efferent neurons (of nerves V and IX-XI), which also proceed mediolaterally and then form ventrolateral nuclei (stages 17, 18). (8) The facial complex shows a distinctive development in that its neural crest arises from the lateral wall of the neural folds/tube. Moreover, the migration of its pharyngeal efferent neurons is delayed, which may be related to the formation of the internal genu, and the motor nucleus begins to appear only at stage 23. (9) The sequence of appearance of afferent constituents is: cranial ganglia (stage 12), mesencephalic trigeminal nucleus (stage 15), vestibular nuclei (stages 18-22), and cochlear nuclei (stage 19). The unsatisfactory term special is avoided and the term pharyngeal for air-breathing vertebrates replaces branchial. The six functional categories used here are vestibulocochlear, somatic afferent, visceral afferent, visceral efferent, pharyngeal efferent, and somatic efferent, together with appropriate abbreviations. The cardiac and hypoglossal neural crests are included, and it is emphasized that all the ectodermal placodes develop within the 'ectodermal ring'.

OBJECTIVE: Fatigue remains one of the most common and distressing symptoms during treatment for advanced cancer. The TIRED trial demonstrated cognitive behavior therapy's (CBT) significant and clinically relevant effects to reduce fatigue among patients with advanced cancer, while graded exercise therapy (GET) did not prove beneficial. The present study aims to determine the mechanisms by which CBT and GET affect fatigue. METHOD: The TIRED trial randomized 134 patients with advanced cancer to CBT (n = 46), GET (n = 42), or usual care (n = 46). At 14 weeks, 126 evaluable patients provided fatigue data and of those 117 received ≥1 CBT or GET session or usual care. We tested a prespecified multiple mediation model with four potential mediators (physical activity, exercise capacity, self-efficacy, and fatigue catastrophizing) assessed at baseline and at 14 weeks. Post-hoc analyses also included perceived physical activity and emotional functioning as potential mediators. RESULTS: A total of 82 of 117 patients completed all required measures. CBT reduced fatigue indirectly through its effect on self-efficacy, ab = -3.292; 97.5% bootstrap CI [-6.518 to -0.598]. CBT participants experienced an increase in fatigue self-efficacy, with greater self-efficacy associated with decreased fatigue severity. There was no evidence that changes in physical activity, exercise capacity, perceived physical activity, fatigue catastrophizing, or emotional functioning mediated CBT's or GET's effects on fatigue. CONCLUSIONS: The effect of CBT was attributable to changes in cognition, that is, increased self-efficacy led to reduced fatigue severity. No significant mediators for GET were found. The findings inform further refinement of interventions for fatigue in this seriously ill population. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

BACKGROUND: The EORTC QLU-C10D is a multiattribute utility measure derived from the cancer-specific quality-of-life questionnaire, the EORTC QLQ-C30. The QLU-C10D contains 10 dimensions (physical, role, social and emotional functioning, pain, fatigue, sleep, appetite, nausea, bowel problems). The objective of this study was to develop a United States value set for the QLU-C10D. METHODS: A US online panel was quota recruited to achieve a representative sample for sex, age (≥18 y), race, and ethnicity. Respondents undertook a discrete choice experiment, each completing 16 choice-pairs, randomly assigned from a total of 960 choice-pairs. Each pair included 2 QLU-C10D health states and duration. Data were analyzed using conditional logistic regression, parameterized to fit the quality-adjusted life-year framework. Utility weights were calculated as the ratio of each dimension-level coefficient to the coefficient for life expectancy. RESULTS: A total of 2480 panel members opted in, 2333 (94%) completed at least 1 choice-pair, and 2273 (92%) completed all choice-pairs. Within dimensions, weights were generally monotonic. Physical functioning, role functioning, and pain were associated with the largest utility weights. Cancer-specific dimensions, such as nausea and bowel problems, were associated with moderate utility decrements, as were general issues such as problems with emotional functioning and social functioning. Sleep problems and fatigue were associated with smaller utility decrements. The value of the worst health state was 0.032, which was slightly greater than 0 (equivalent to being dead). CONCLUSIONS: This study provides the US-specific value set for the QLU-C10D. These estimated health state scores, based on responses to the EORTC QLQ-C30 questionnaire, can be used to evaluate the cost-utility of oncology treatments.

The staging of human embryos, as distinct from seriation, depends on a morphological scheme devised by Streeter and completed by O'Rahilly, who proposed the term Carnegie stages. To avoid misconceptions and errors, and to place new findings in perspective, it is necessary to summarize the essentials of the Carnegie system: (1) Twenty-three stages cover the embryonic period, i. e. the first 8 postfertilizational weeks of development. (2) The system is based on internal as well as external features, and the use of only external criteria is subject to serious limitations. For example, precise delineation of stages 19-23 and of the embryonic-fetal transition depends on histological examination. (3) Prenatal measurements are not an integral component of the staging system, and hence a stage should never be assigned merely on the basis of embryonic length. A 20-mm embryo, for example, could belong to any of three stages. Measurements, however, are important for the assessment of age, and very few measurements are available for staged embryos. Presented here and based on accurate staging are the maximum diameter of the chorionic sac, the crown-heel length, the greatest length exclusive of the lower limbs, the biparietal diameter, the head circumference, the length of the hindbrain, the total length of the brain, and the lengths of the limbs as well as of their segments, including the foot length. (4) Prenatal ages are also not an integral part of the staging system and hence a stage should never be assigned merely on the basis of prenatal age. Ages, however, are of clinical importance and their estimate has been rendered more precise by accurate timing of fertilization followed by ultrasonography. Prenatal age is postfertilizational and hence some 2 weeks less than the postmenstrual interval. The term gestational age is ambiguous and should be discarded. Presented here is a new graph showing proposed estimates of age in relation to stages and based on current information.

BACKGROUND: Colorectal cancer (CRC) is prevalent in the developed world. Favourable survival rates highlight the need to better understand CRC survivors' experiences of long-term impacts of treatment, which can in turn inform decision making. This systematic review aimed to identify and synthesise CRC survivors' experiences of long-term impacts on health-related quality of life. METHODS: We searched Medline, Embase and PsychINFO from inception to January 2019. Qualitative studies describing CRC survivors' experiences at least 1-year post-treatment were included. Study eligibility, quality assessment (COREQ guidelines), and data synthesis was performed independently by two reviewers and discussed with the study team. RESULTS: Of 1363 papers retrieved, 20 reporting 15 studies met eligibility. Thematic synthesis produced 12 themes: symptoms, physical, social, psychological and sexual functioning, impact on relationships, informal care needs provided by family/friend, supportive care needs provided by healthcare professional, health care experiences, health behaviour, financial toxicity and occupational experiences. Stoma problems (e.g. leakage, skin irritation) were common in ostomates. Survivors with no/reversed stoma experienced unexpected, long-term altered and unpredictable bowel functioning. Survivors often regulated timing, amount and foods consumed to manage bowel functioning. Less common symptoms included fatigue, impaired sleep and anal pain. Stoma problems and altered bowel functioning impaired survivors' physical, social, sexual and psychological functioning. Cognitive functioning and heredity issues were not reported in any paper. CONCLUSION: CRC survivors experience ongoing symptoms and functioning impairments more than 1-year post-treatment completion. Many survivors find their own ways to manage symptoms rather than seek professional help. Follow-up care for CRC survivors should integrate screening for long-term effects and provide targeted supportive care.
RESUMO
OBJECTIVE: Fatigue is a prevalent and long-lasting symptom among patients with cancer that is known to be worsened by patients' catastrophizing thoughts about their fatigue. Spouses are also burdened by patient fatigue, which may lead them to catastrophize as well. Based on the dyadic coping literature, this study hypothesized that patient and spouse catastrophizing translate into worse fatigue through co-rumination-couples' communications dwelling on the negative aspects of fatigue (H1). While maladaptive for fatigue, co-rumination also was expected to foster couple relationship satisfaction (H2). METHOD: Posttreatment patients with cancer and their spouses (n = 101 dyads) completed daily diaries for 14 days. Patients reported on their momentary fatigue severity. Both couple members reported on their catastrophizing about the patients' fatigue, co-rumination, and their momentary relationship satisfaction. Multilevel structural equation modeling was applied to test within-person actor- and partner-effects between catastrophizing, co-rumination, and changes in fatigue (H1) and between co-rumination and changes in relationship satisfaction (H2). RESULTS: Whereas patient catastrophizing was directly related to their fatigue (b = 0.52, 95% credibility interval [CI] [0.09, 0.95]), as hypothesized, the effect of spouse catastrophizing on patient fatigue was mediated through co-rumination (indirect effect = 0.32, 95% CI [0.07, 0.60]). Unexpectedly, patient- and spouse-reported co-rumination were unrelated to both couple members' relationship satisfaction. CONCLUSIONS: Spouse catastrophizing contributes to patient fatigue severity through couples' ruminative communications. Co-rumination was not related to relationship satisfaction. Reducing patient and spouse catastrophizing and fostering adaptive dyadic communication in daily life could be targets for future interventions aiming to relieve fatigue in patients after completion of cancer treatment.

A review of the early prenatal development of the human brain has been prepared following a long-standing investigation of 192 embryos. The precise sequence of developmental events has been traced with the aid of accurate morphological staging. The three major divisions of the brain appear in the walls of the completely open neural groove at 3(1/2) postfertilizational weeks (stage 9). They do not develop as "cerebral vesicles" in a closed neural tube. The 16 neuromeres and the various subdivisions of the neural crest are highlighted. It is stressed that only two neuropores are normally found in the human. The telencephalon can be distinguished as early as 4 weeks (stage 10) and the five chief subdivisions of the brain are recognizable at 5 weeks (stage 15). The development of the medial (diencephalic) and lateral (telencephalic) ventricular eminences (so-called Ganglienhügel) is elaborated, and their role in the formation of the basal nuclei is clarified. The cortical plate and subplate have been identified as early as 7 weeks (stage 21). Finally, it is pointed out that the timing of the origin of many congenital anomalies of the nervous system shows the special importance of the embryonic period, i.e., the first 8 postfertilizational weeks.
