Abstract
Anyons are particles intermediate between fermions and bosons, characterized by a nontrivial exchange phase, yielding remarkable braiding statistics. Recent experiments have shown that anyonic braiding has observable consequences on edge transport in the fractional quantum Hall effect (FQHE). Here, we study transport signatures of anyonic braiding when the anyons have a finite width. We show that the width of the anyons, even when extremely small, can have a tremendous impact on transport properties and braiding signatures. In particular, we find that taking the finite width into account allows us to explain recent experimental results on the FQHE at filling factor 2/5 [M. Ruelle et al., Phys. Rev. X 13, 011031 (2023)PRXHAE2160-330810.1103/PhysRevX.13.011031]. Our work shows that the finite width of anyons crucially influences setups involving anyonic braiding, especially when the exchange phase is larger than π/2.

Abstract
PURPOSE Cancer-related fatigue (CRF) is a common side effect of cancer and cancer treatment that significantly impairs the quality of life and can persist for years after treatment completion. Although fatigue is often associated with cancer treatment, it is also a result of the disease itself, even before intervention. CRF at the time of diagnosis may affect treatment timing or completion and is a consistent predictor of post-treatment fatigue at any time. The mechanisms underlying CRF are multidimensional and not well understood, particularly at the time of diagnosis. METHODS Sixty-five breast cancer patients at the time of diagnosis were included. The participants completed self-assessment questionnaires about CRF, sleep disturbances, and emotional symptoms and wore an accelerometer to assess levels of spontaneous physical activity and sleep quality. During the experimental session, the participants underwent cognitive, neuromuscular, and exercise metabolism evaluations. RESULTS Using augmented backward elimination regression, this study found that emotional symptoms and perceived sleep disturbances were the strongest predictors of CRF (adjusted r2 = 0.51). Neuromuscular fatigability and sleep disturbance were also associated with physical dimensions, whereas cognitive performance was associated with cognitive dimensions. CONCLUSION At the time of diagnosis, emotional and cognitive dimensions are over-represented compared to the general population, and specific subdimensions have specific predictors that support the idea of distinct mechanisms. Evaluating CRF subdimensions and their potential mechanisms at the time of diagnosis would be particularly relevant for identifying high-risk patients and offering them appropriate interventions. TRIAL REGISTRATION This study was registered at ClinicalTrials.gov (NCT04391543) in May, 2020.

Professional quality of life in animal research personnel is linked to retention & job satisfaction: A mixed-methods cross-sectional survey on compassion fatigue in the USA. PLoS One 2024; 19:e0298744. [PMID: 38626016 PMCID: PMC11020707 DOI: 10.1371/journal.pone.0298744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 01/29/2024] [Indexed: 04/18/2024] Open
Abstract
BACKGROUND Working with research animals can be both rewarding and challenging. The rewarding part of the work is associated with understanding the necessity for animal research to improve the health of humans and animals and the knowledge that one can provide care and compassion for the animals. Challenges with animal research include witnessing stress/pain in animals necessitated by scientific requirements, end of study euthanasia, and societal stigmatization about animal research. These challenges could be compounded with more general workplace stresses, in turn, impacting job retention and satisfaction. However, these factors have yet to be formally evaluated. Therefore, the purpose of this survey was to comprehensively evaluate professional quality of life's correlation with key workplace metrics. METHODS Six institutions were recruited to participate in a longitudinal intervention trial on compassion fatigue resiliency. This manuscript reports key baseline metrics from this survey. A cross-sectional mixed methods survey was developed to evaluate professional quality of life, job satisfaction, retention, and factors influencing compassion fatigue resiliency. Quantitative data were analyzed via general linear models and qualitative data were analyzed by theme. RESULTS Baseline data was collected from 198 participants. Personnel who reported higher compassion satisfaction also reported higher retention and job satisfaction. Conversely, personnel who reported higher burnout also reported lower job satisfaction. In response to open-ended questions, participants said their compassion fatigue was impacted by institutional culture (70% of participants), animal research (58%), general mental health (41%), and specific compassion fatigue support (24%). CONCLUSIONS In conclusion, these results show that professional quality of life is related to important operational metrics of job satisfaction and retention. Furthermore, compassion fatigue is impacted by factors beyond working with research animals, including institutional culture and general mental health support. Overall, this project provides rationale and insight for institutional support of compassion fatigue resiliency.

Abstract
Primary antiphospholipid syndrome is characterized by thrombosis and autoantibodies directed against phospholipids or associated proteins. The genetic etiology of PAPS remains unknown. We enrolled 21 patients with thromboembolic events associated to lupus anticoagulant, anticardiolipin and anti β2 glycoprotein1 autoantibodies. We performed whole exome sequencing and a systematic variant-based analysis in genes associated with thrombosis, in candidate genes previously associated with APS or inborn errors of immunity. Data were compared to public databases and to a control cohort of 873 non-autoimmune patients. Variants were identified following a state-of-the-art pipeline. Enrichment analysis was performed by comparing with the control cohort. We found an absence of significant HLA bias and genetic heterogeneity in these patients, including when testing combinations of rare variants in genes encoding for proteins involved in thrombosis and of variants in genes linked with inborn errors of immunity. These results provide evidence of genetic heterogeneity in PAPS, even in a homogenous series of triple positive patients. At the individual scale, a combination of variants may participate to the breakdown of B cell tolerance and to the vessel damage.

Abstract
We present the precision measurements of 11 years of daily cosmic positron fluxes in the rigidity range from 1.00 to 41.9 GV based on 3.4×10^{6} positrons collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The positron fluxes show distinctly different time variations from the electron fluxes at short and long timescales. A hysteresis between the electron fluxes and the positron fluxes is observed with a significance greater than 5σ at rigidities below 8.5 GV. On the contrary, the positron fluxes and the proton fluxes show similar time variation. Remarkably, we found that positron fluxes are modulated more than proton fluxes with a significance greater than 5σ for rigidities below 7 GV. These continuous daily positron fluxes, together with AMS daily electron, proton, and helium fluxes over an 11-year solar cycle, provide unique input to the understanding of both the charge-sign and mass dependencies of cosmic rays in the heliosphere.

Abstract
Antiphospholipid syndrome (APS) is a chronic autoimmune disease involving vascular thrombosis and/or obstetric morbidity and persistent antibodies to phospholipids or certain phospholipid-associated proteins. It is a rare condition in adults and even rarer in children. The diagnosis of APS can be facilitated by the use of classification criteria based on a combination of clinical and biological features. APS may be rapidly progressive with multiple, often synchronous thromboses, resulting in life-threatening multiple organ failure. This form is known as "catastrophic antiphospholipid syndrome" (CAPS). It may be primary or associated with systemic lupus erythematosus (associated APS) and in very rare cases with other systemic autoimmune diseases. General practitioners and paediatricians may encounter APS in patients with one or more vascular thromboses. Because APS is so rare and difficult to diagnosis (risk of overdiagnosis) any suspected case should be confirmed rapidly and sometimes urgently by an APS specialist. First-line treatment of thrombotic events in APS includes heparin followed by long-term anticoagulation with a VKA, usually warfarin. Except in the specific case of stroke, anticoagulants should be started as early as possible. Any temporary discontinuation of anticoagulants is associated with a high risk of thrombosis in APS. A reference/competence centre specialised in autoimmune diseases must be urgently consulted for the therapeutic management of CAPS.

Abstract
We report the properties of primary cosmic-ray sulfur (S) in the rigidity range 2.15 GV to 3.0 TV based on 0.38×10^{6} sulfur nuclei collected by the Alpha Magnetic Spectrometer experiment (AMS). We observed that above 90 GV the rigidity dependence of the S flux is identical to the rigidity dependence of Ne-Mg-Si fluxes, which is different from the rigidity dependence of the He-C-O-Fe fluxes. We found that, similar to N, Na, and Al cosmic rays, over the entire rigidity range, the traditional primary cosmic rays S, Ne, Mg, and C all have sizeable secondary components, and the S, Ne, and Mg fluxes are well described by the weighted sum of the primary silicon flux and the secondary fluorine flux, and the C flux is well described by the weighted sum of the primary oxygen flux and the secondary boron flux. The primary and secondary contributions of the traditional primary cosmic-ray fluxes of C, Ne, Mg, and S (even Z elements) are distinctly different from the primary and secondary contributions of the N, Na, and Al (odd Z elements) fluxes. The abundance ratio at the source for S/Si is 0.167±0.006, for Ne/Si is 0.833±0.025, for Mg/Si is 0.994±0.029, and for C/O is 0.836±0.025. These values are determined independent of cosmic-ray propagation.

Abstract
The fractional quantum Hall effect (FQHE) is known to host anyons, quasiparticles whose statistics is intermediate between bosonic and fermionic. We show here that Hong-Ou-Mandel (HOM) interferences between excitations created by narrow voltage pulses on the edge states of a FQHE system at low temperature show a direct signature of anyonic statistics. The width of the HOM dip is universally fixed by the thermal time scale, independently of the intrinsic width of the excited fractional wave packets. This universal width can be related to the anyonic braiding of the incoming excitations with thermal fluctuations created at the quantum point contact. We show that this effect could be realistically observed with periodic trains of narrow voltage pulses using current experimental techniques.

Abstract
We present the precision measurements of 11 years of daily cosmic electron fluxes in the rigidity interval from 1.00 to 41.9 GV based on 2.0×10^{8} electrons collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The electron fluxes exhibit variations on multiple timescales. Recurrent electron flux variations with periods of 27 days, 13.5 days, and 9 days are observed. We find that the electron fluxes show distinctly different time variations from the proton fluxes. Remarkably, a hysteresis between the electron flux and the proton flux is observed with a significance of greater than 6σ at rigidities below 8.5 GV. Furthermore, significant structures in the electron-proton hysteresis are observed corresponding to sharp structures in both fluxes. This continuous daily electron data provide unique input to the understanding of the charge sign dependence of cosmic rays over an 11-year solar cycle.

Abstract
We present the precision measurement of 2824 daily helium fluxes in cosmic rays from May 20, 2011 to October 29, 2019 in the rigidity interval from 1.71 to 100 GV based on 7.6×10^{8} helium nuclei collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The helium flux and the helium to proton flux ratio exhibit variations on multiple timescales. In nearly all the time intervals from 2014 to 2018, we observed recurrent helium flux variations with a period of 27 days. Shorter periods of 9 days and 13.5 days are observed in 2016. The strength of all three periodicities changes with time and rigidity. In the entire time period, we found that below ∼7 GV the helium flux exhibits larger time variations than the proton flux, and above ∼7 GV the helium to proton flux ratio is time independent. Remarkably, below 2.4 GV a hysteresis between the helium to proton flux ratio and the helium flux was observed at greater than the 7σ level. This shows that at low rigidity the modulation of the helium to proton flux ratio is different before and after the solar maximum in 2014.

Abstract
INTRODUCTION Metastasis to retropharyngeal lymph nodes (RPLN) from oral squamous cell carcinoma is rare and associated with poor outcomes. The poor prognosis of RPLN is multifactorial and includes the clinicopathological aggressiveness of the primary disease and the late presentation. The aim of this systematic review is to assess the evidence on RPLN in patients diagnosed with oral squamous cell carcinoma (OSCC), the quality of the diagnostic modalities and the available treatment options. We aimed to analyse the overall survival of these patients diagnosed with RPLN. METHODS A systematic review was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The initial literature search generated 289 articles. A total of 11 papers satisfied our criteria. Eight papers provided enough data to perform survival analysis and 3 papers compared the diagnostic modalities used in the detection of RPLN. RESULTS A total of 73 OSCC patients diagnosed with RPLN metastasis were identified. The most common primary tumour subsites included the tongue (20), buccal mucosa (15) and gingiva (11). The cumulative 5-year OS rate was 17.8% while the 2-year overall survival was 35.9%. CONCLUSION The presence of nodal metastasis is an independent prognostic factor in head and neck cancer. In this study, RPLN metastasis had a poorer prognosis (5 years overall survival is 17.8%) when compared to the survival rate of oral cancer without RPLN metastasis (5 years overall survival is 40%). There was no statistically significant difference between the overall survival in primary RPLN metastasis and recurrent RPLN disease.

Abstract
BackgroundMixed connective tissue disease (MCTD) is a systemic auto-immune disorder, being probably the least common among the connective tissue diseases. Symptoms can be severe and could affect health-related quality of life (HRQoL). Identification of the burden of MCTD patients is of key importance to provide appropriate pharmacological and non-pharmacological care. No reports on HRQoL have been published in adult patients with MCTD.ObjectivesTo perform an explorative study to evaluate HRQoL and its main determinants in MCTD patients, and compare HRQoL between MCTD and matched systemic sclerosis (SSc) patients.MethodsMCTD patients fulfilling the Kahn criteria and participating in the MCTD prospective follow-up cohort of the Leiden University Medical Center were included. In addition, SSc patients matched for age, gender and disease duration were included for comparison. Data on disease characteristics, functional disability and HRQoL were collected annually for both disease groups. HRQoL was evaluated using the 36-Item Short Form Health Survey (SF36) and EuroQol (EQ5D). At baseline, HRQoL, as reflected by SF36 mental component score (MCS), SF 36 physical component score (PCS) and EQ5D were compared between MCTD and SSc patients. For MCTD patients, factors associated with HRQoL at baseline were identified using linear regression and change in HRQoL over 3 years was evaluated using linear mixed models. In addition, characteristics of MCTD patients who showed worsening of MCS and/or had PCS superior to the minimal clinical important difference of three points were identified.ResultsThirty-four MCTD patients (121 visits; 82% female, mean age 42 years, median disease duration 45 months) and 102 SSc patients (424 visits; 82% female, mean age 45 years, median disease duration 49 months) were included. At baseline, MCTD-patients more often had ILD (47% vs. 34%, p=0.027), cardiac involvement (30% vs. 2%, p<0.001), synovitis (26% vs. 11%, p=0.004) and myositis (15% vs. 1%, p=0.001) compared to SSc patients, whereas SSc patients more often used immunosuppressive treatments except for hydroxychloroquine (MCTD:18% vs. SSc:7%, p=0.007).Baseline HRQoL in MCTD was comparable to HRQoL in SSc, with mean SF36-PCS of 40.2 (SD:9.1) and mean SF36-MCS of 44.9 (SD:9.9), which is (nearly) one standard deviation lower than the general Dutch population. The SF36 subscore “general health perception” was the most impacted in both groups (MCTD: 38.5 [SD:7.0], SSc: 39.9 [SD:8.9]). The median EQ5DNL was 0.38 (IQR:0.14 – 0.54) and comparable between SSc and MCTD.At baseline, in MCTD, ILD was significantly associated with SF36-PCS (β:6.98, 95% CI: 1.10 to 12.86) and SF36-MCS (β:-8.10, 95% CI:-14.93 to -1.26). Sclerodactyly was significantly associated with EQ5DNL (β:0.006; 95% CI:0.002 to 0.010) and SF36-PCS (β:0.12, 95% CI:0.03 to 0.21). No other significant associations were identified.Over time, in MCTD, both the SF36-MCS and SF36-PCS improved significantly (MCS: β:2.35/year [95% CI:0.58 to 4.13], PCS: β:1.34/year [95% CI:0.03 to 2.65), whereas EQ5DNL was stable. Explorative analyses did not reveal a specific clinical characteristic with significant impact on the change of HRQoL over time. With an MCID of 3 points on the MCS and PCS, 7 MCTD-patients worsened on the MCS and 3 on the PCS. Patients who showed worsening of MCS over time tended to be older, more often had ILD, sclerodactyly and GI complaints, and had worse exercise tolerance. All these differences did not reach statistical significance. The patients who decreased PCS more often had ILD (100% vs. 41%, p=0.015), and used glucocorticoids more often (33% vs. 0%, p=0.046), were slightly older and had a worse exercise tolerance as compared to those who showed a stable/improving PCS over time.ConclusionLike in SSc, HRQoL is significantly impaired in MCTD, especially the general health perception of patients. Cardiac involvement, ILD, age and worse functional disability might specifically impact HRQoL in MCTD. However, these associations need further evaluations in larger cohorts.Disclosure of InterestsNone declared

Abstract
BACKGROUND Major causes of under-5 child deaths in South Africa (SA) are well recognised, and child mortality rates are falling. The focus of child health is therefore shifting from survival to disease prevention and thriving, but local data on the non-fatal disease burden are limited. Furthermore, COVID-19 has affected children's health and wellbeing, both directly and indirectly. OBJECTIVES To describe the pattern of disease on admission of children at different levels of care, and assess whether this has been affected by COVID-19. METHODS Retrospective reviews of children's admission and discharge registers were conducted for all general hospitals in iLembe and uMgungundlovu districts in KwaZulu-Natal Province, SA, from January 2018 to September 2020. The Global Burden of Disease framework was adapted to create a data capture sheet with four broad diagnostic categories and 37 specific cause categories. Monthly admission numbers were recorded per cause category, and basic descriptive analysis was completed in Microsoft Excel. RESULTS Overall, 36 288 admissions were recorded across 18 hospital wards, 32.0% at district, 49.8% at regional and 18.2% at tertiary level. Communicable diseases, perinatal conditions and nutritional deficiencies (CPNs) accounted for 37.4% of admissions, non-communicable diseases (NCDs) for 43.5% and injuries for 17.1%. The distribution of broad diagnostic categories varied across levels of care, with CPNs being more common at district level and NCDs more common at regional and tertiary levels. Unintentional injuries represented the most common cause category (16.6%), ahead of lower respiratory tract infections (16.1%), neurological conditions (13.6%) and diarrhoeal disease (8.4%). The start of the local COVID-19 outbreak coincided with a 43.1% decline in the mean number of monthly admissions. Admissions due to neonatal conditions and intentional injuries remained constant during the COVID-19 outbreak, while those due to other disease groups (particularly respiratory infections) declined. CONCLUSIONS Our study confirms previous concerns around a high burden of childhood injuries in our context. Continued efforts are needed to prevent and treat traditional neonatal and childhood illnesses. Concurrently, the management of NCDs should be prioritised, and evidence-based strategies are sorely needed to address the high injury burden in SA.

Abstract
We consider the non-equilibrium zero frequency noise generated by a temperature gradient applied on a device composed of two normal leads separated by a quantum dot. We recall the derivation of the scattering theory for non-equilibrium noise for a general situation where both a bias voltage and a temperature gradient can coexist and put it in a historical perspective. We provide a microscopic derivation of zero frequency noise through a quantum dot based on a tight binding Hamiltonian, which constitutes a generalization of the seminal result obtained for the current in the context of the Keldysh formalism. For a single level quantum dot, the obtained transmission coefficient entering the scattering formula for the non-equilibrium noise corresponds to a Breit-Wigner resonance. We compute the delta-Tnoise as a function of the dot level position, and for a broad range of values of the dot level width, in the Breit-Wigner case, for two relevant situations which were considered recently in two separate experiments. In the regime where the two reservoir temperatures are comparable, our gradient expansion shows that the delta-Tnoise is dominated by its quadratic contribution, and is minimal close to resonance. In the opposite regime where one reservoir is much colder, the gradient expansion fails and we find the noise to be typically linear in temperature before saturating. In both situations, we conclude with a short discussion of the case where both a voltage bias and a temperature gradient are present, in order to address the potential competition with thermoelectric effects.

Abstract
We present the precision measurement of the daily proton fluxes in cosmic rays from May 20, 2011 to October 29, 2019 (a total of 2824 days or 114 Bartels rotations) in the rigidity interval from 1 to 100 GV based on 5.5×10^{9} protons collected with the Alpha Magnetic Spectrometer aboard the International Space Station. The proton fluxes exhibit variations on multiple timescales. From 2014 to 2018, we observed recurrent flux variations with a period of 27 days. Shorter periods of 9 days and 13.5 days are observed in 2016. The strength of all three periodicities changes with time and rigidity. The rigidity dependence of the 27-day periodicity is different from the rigidity dependences of 9-day and 13.5-day periods. Unexpectedly, the strength of 9-day and 13.5-day periodicities increases with increasing rigidities up to ∼10 GV and ∼20 GV, respectively. Then the strength of the periodicities decreases with increasing rigidity up to 100 GV.

Abstract
Background Cancer-related fatigue (CRF) is the most common side effect of cancer and cancer treatment. CRF prevalence is up to 50% in breast cancer patients and can continue several years after cancer remission. This persistent subjective sense of exhaustion is multifactorial. Numerous parameters have been evidenced to be related to CRF across biological, physical, psychological, social and/or behavioral dimensions. Although CRF has been studied for many years, the majority of previous studies focused on only one dimension, i.e., physical function. Moreover, few studies investigated CRF longitudinally with repeated measures. These are the two main obstacles that limit the understanding of CRF mechanisms. The purpose of this study is to create a biopsychosocial model of CRF with simultaneous and longitudinal anthropometric, clinical, biological, physical, psychological and sociological parameters. Methods BIOCARE FActory is a multicentric prospective study that will consist of an 18-month follow-up of 200 women diagnosed with breast cancer. Four visits will be scheduled at diagnosis, after treatments, and 12 and 18 months after diagnosis. The same procedure will be followed for each visit. Each session will be composed of anthropometric data collection, a semi-structured interview, cognitive tests, postural control tests, neuromuscular fatigability tests and a cardiorespiratory fitness test. Clinical and biological data will be collected during medical follow-ups. Participants will also complete questionnaires to assess psychological aspects and quality of life and wear an actigraphy device. Using a structural equation modeling analysis (SEM), collected data will build a biopsychosocial model of CRF, including the physiological, biological, psychological, behavioral and social dimensions of CRF. Discussion This study aims to highlight the dynamics of CRF and its correlates from diagnosis to post treatment. SEM analysis could examine some relations between potential mechanisms and CRF. Thus, the biopsychosocial model will contribute to a better understanding of CRF and its underlying mechanisms from diagnosis to the aftermaths of cancer and its treatments. Trial registration This study is registered at ClinicalTrials.gov (NCT04391543), May 2020.

Abstract
Abstract
Introduction
Gorlin Goltz syndrome (GGS) is a rare, hereditary, AD condition with multiple BCCs, odontogenic keratocysts (Jaw cysts), calcification of falx cerebri, skeletal anomalies & a predisposition to neoplasms like medulloblastomas, fibromas and rhabdomyosarcomas.
Aim
We present a rare case of a Squamous cell carcinoma (SCC) developing in a Maxillary odontogenic keratocyst in a 32-year male with GGS.
Discussion
This patient was referred to the OMFS unit with a non-healing UL3 extraction socket and exophytic growth. Initial biopsies suggested an atypical squamo-proliferative lesion, however a repeat biopsy demonstrated an invasive SCC arising from a background odontogenic keratocyst of the maxilla. He was initially reluctant to undergo a staging CT scan to avoid risks of developing further BCCs due to IR exposure. This was eventually performed as per H&N MDT recommendation & showed a T4aN0M0 SCC of the left maxilla and bilateral multiple mandibular odontogenic keratocysts. He underwent a left maxillectomy, left neck dissection & reconstruction with a DCIA free flap, but did not want his mandibular keratocysts treated at the same time. Complete tumour clearance was achieved with no involved neck nodes & he remains disease-free at 4 months postoperatively. Although for a T4 tumour he would have needed postoperative radiotherapy, in view of the GGS, no adjuvant treatment was indicated.
Conclusions
SCC developing in a maxillary OKC is exceedingly rare with only two previous cases reported in GG syndrome. This is the first reported case of a GGS patient with oral SCC undergoing a complex free flap reconstruction.

Abstract
Rest-activity rhythm (RAR) disruptions are frequently associated with chemotherapy in breast cancer (BC), but they are less known in BC with endocrine therapy. The aim of this ancillary study was to characterize the RAR and estimated sleep characteristics from actigraphy in BC patients either treated (ET+) or untreated with endocrine therapy (ET-), compared to healthy controls (HC) and using a cross-sectional design. Eighteen ET+, 18 ET- and 16 HC completed questionnaires and wore wrist actigraphs at home for 2 weeks. Parametric and non-parametric RAR, sleep parameters, and quality of life were compared between groups (p<0.05). BC groups presented lower daytime activity than HC according to RAR analysis (mesor and M10 parameters). Compared to HC, ET- had lower inter-daily stability and ET+ had greater sleep complaints. Compared to ET-, ET+ had lower sleep efficiency, more time awake and higher activity levels at night, as assessed with actigraphy.
