Abstract
OBJECTIVE Intracerebral hemorrhage (ICH) is a devastating cerebrovascular disease of the central nervous system. In this study, we aimed to investigate plasma ZCCHC14 expression and its correlation with the diagnosis, prognosis, and clinical features of ICH. PATIENTS AND METHODS The plasma levels of ZCCHC14, TNF-α, IL-6, and IL-10 were dynamically detected among 130 ICH patients and 60 corresponding healthy subjects. A receiver operating characteristic (ROC) curve was used for the statistical analysis of the diagnostic and prognostic efficacy of ICH. RESULTS Hypertension (p = 0.005), ARB application (p = 0.014), ZCCHC14 level (p < 0.001), TNF-α (p < 0.001), IL-6 (p < 0.001), and IL-10 (p < 0.001) were found to be different between ICH patients and healthy controls. Multiple logistic regression analysis indicated that ZCCHC14 levels at admission were significantly different between the two groups (p = 0.002, OR = 0.440, 95% CI 0.290-0.718). Plasma ZCCHC14 levels dynamically changed, increasing at admission, and peaking on day 7. ZCCHC14 was a potential diagnostic marker for ICH (AUC = 0.953, p < 0.0001, 95% CI: 0.901-1.004) with a specificity and sensitivity of 84.6% and 95.5%, respectively. The plasma ZCCHC14 level was negatively correlated with IL-6 concentration (p = 0.024, r = -0.311) but was positively correlated with IL-10 concentration (p = 0.041, r = 0.298). Furthermore, the plasma ZCCHC14 level was correlated with hypertension (p = 0.005), GOS (p = 0.025), bleeding volume (p < 0.001), midline shift (p = 0.003), and poor outcome (p = 0.006). The low ZCCHC14 expression group had poorer outcomes (death or severe disability) than high ZCCHC14 expression group (Breslow, p < 0.001). CONCLUSIONS We found that the plasma ZCCHC14 level might be a potential biomarker for both the early diagnosis of and prediction of outcomes in ICH.

Abstract
BACKGROUND: Occupational exposure-related risk of Mycobacterium tuberculosis infection has been reported for village doctors in China. This prospective study aims to estimate the infection acquisition in this key population.METHODS: At baseline, all village doctors registered in Zhongmu County were tested by QuantiFERON®-TB Gold In-Tube (QFT) and QuantiFERON®-TB Gold Plus (QFT-Plus) in parallel. Those negatives for either of the tests were retested to identify conversions at the 2-year follow-up investigation.RESULTS: A total of 367 eligible participants completed the 2-year follow-up survey with frequency of conversion of 5.0% (18/361) for QFT and 6.1% (21/343) for QFT-Plus. The agreement of follow-up results between the tests was 93.2% with a κ coefficient of 0.43 (95%CI 0.20-0.65). Among QFT-Plus convertors, the difference between TB1 and TB2 tubes (TB2-TB1) was significantly increased as compared with baseline results (P = 0.039). Participants from the villages with occurrence of microbiologically confirmed pulmonary TB showed higher frequency of QFT conversions (11.0% vs. 3.2%, P = 0.011) and QFT-Plus conversions (12.3% vs. 4.4%, P = 0.027) than those from the villages without occurrence.CONCLUSION: Our results consistently suggest that capability on occupational protection and M. tuberculosis infection control should be improved in village doctors in China.

Abstract
Objective: To investigate the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with pharyngeal symptoms. Methods: From January 10 to May 15, 2020, clinical data of 1 228 patients with COVID-19 in Renmin Hospital of Wuhan University was collected (554 males and 674 females, with the range of age from 10 to 95 years old, the average age was 55.2 years old). The patients were divided into pharyngeal symptoms group (PS, 126 cases) and non-pharyngeal symptoms group (Non-PS, 1 102 cases) according to the presence or absence of pharyngeal symptoms such as pharyngalgia, pharyngeal dryness, pharyngeal itching, and pharyngeal foreign body sensation. The clinical data in terms of age, sex, medical history, duration of symptoms, treatment time, clinical classification, pulmonary imaging findings, whole blood cell count, serum hypersensitivity C-reactive protein, C-reactive protein, procalcitonin were statistically analyzed between the two groups. Chi-square, Fisher's exact test and Mann-Whitney U test were used for statistical analysis. Results: The most common pharyngeal symptoms were pharyngalgia (59.52%, 75/126), followed by foreign body sensation (23.02%, 29/126), pharyngeal dryness (8.73%, 11/126), and itching (8.73%, 11/126). The median age of the patients in the PS group was 51.50 years old, which was less than 57.50 years old in the non-PS group, showing a significant difference (P<0.05). The female cases accounted for 65.08% (82/126), which was higher than 53.72% (592/1 102) of the non-PS group (P<0.05). The incidence of bilateral lung inflammation confirmed by CT images was 73.81% (93/126), which was significantly lower than 83.48% (920/1 102) in the non-PS group (P<0.05). No significant differences were shown in the proportion of patients with clinical types, treatment days, duration of symptoms, white blood cell count, lymphocyte count, lymphocyte percentage, eosinophil count, eosinophil percentage, hypersensitive C-reactive protein, C-reactive protein, D-dimer, procalcitonin and other indicators (P>0.05). Conclusions: The incidence of pharyngeal symptoms in patients with COVID-19 is 10.26%. Most of these symptoms occur before or at the same time as the common symptoms of the disease. Therefore, patients with such symptoms may bring a greater risk of infection to otolaryngologist. According to the current clinical classification criteria, pharyngeal symptoms have no obvious correlation with the degree of the disease; but the presence of pharyngeal symptoms may suggest a milder clinical presentation and a better prognosis.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has resulted in millions of patients
infected worldwide and indirectly affecting even more individuals through disruption of
daily living. Long-term adverse outcomes have been reported with similar diseases from
other coronaviruses, namely Middle East Respiratory Syndrome (MERS) and Severe Acute
Respiratory Syndrome (SARS). Emerging evidence suggests that COVID-19 adversely affects
different systems in the human body. This review summarizes the current evidence on the
short-term adverse health outcomes and assesses the risk of potential long-term adverse
outcomes of COVID-19. Major adverse outcomes were found to affect different body systems:
immune system (including but not limited to Guillain-Barré syndrome and paediatric
inflammatory multisystem syndrome), respiratory system (lung fibrosis and pulmonary
thromboembolism), cardiovascular system (cardiomyopathy and coagulopathy), neurological
system (sensory dysfunction and stroke), as well as cutaneous and gastrointestinal
manifestations, impaired hepatic and renal function. Mental health in patients with
COVID-19 was also found to be adversely affected. The burden of caring for COVID-19
survivors is likely to be huge. Therefore, it is important for policy makers to develop
comprehensive strategies in providing resources and capacity in the healthcare system.
Future epidemiological studies are needed to further investigate the long-term impact on
COVID-19 survivors.

Abstract
Objective: To analysis the clinical characteristics and to summarize therapy experience of pediatric patients with cardiac syncope caused by anomalous origin of the left coronary artery from the right sinus (ALCA-R). Methods: We retrospectively analyzed the clinical data including clinical manifestations, myocardial injury biomarkers, radiological features, treatments and prognoses of pediatric patients with ALCA-R who were admitted to Beijing Children's Hospital from November 2015 to June 2018. Results: Four female patients were included in this analysis, age of onset was 7 to 14 years. All the patients presented with exercise-induced syncope and acute myocardial infarction. During the course, three patients presented with acute left heart failure, and one patient had history of sudden cardiac arrest. Laboratory data showed significant elevation of both the creatine kinase and troponin levels in four patients. All electrocardiogram (ECG) showed left main coronary artery occlusion, echocardiography suggested the possible anomalous origin of the left coronary artery in one child. Coronary CT angiography (CTA) revealed there was no coronary ostium in the left coronary sinus, and the left coronary artery had an anomalous origin from the right sinus. The left main coronary artery passed between the ascending artery and the root of the main pulmonary artery, which was compressed by these two large vessels. Two patients underwent cardiac magnetic resonance examination, which detected late gadolinium enhancement in ALCA-R with an interarterial course. Unroofing of the left coronary ostium (cut-back procedure) was performed in two patients, and the other two patients who were not operated were recommended to restrict their physical activities. During a regular follow-up period of 12-43 months, all the children survived without recurrent cardiovascular event. Conclusion: If an adolescent presents with exercise-induced syncope, acute myocardial infarction and even sudden death, and ECG shows left main coronary artery occlusion characteristics, we should consider the possibility of developmental abnormality of coronary artery, particularly the ALCA-R. Once diagnosed as ALCA-R, patients should be recommended to avoid strenuous activities,early recognition and surgical treatment are imperative for these patients.

Abstract
OBJECTIVE To explore the effects of long non-coding ribonucleic acid (lncRNA) maternally expressed gene 3 (MEG3) on the proliferation and apoptosis of hypoxic myocardial cells by regulating the expression of forkhead box O1 (FoxO1). MATERIALS AND METHODS The myocardial A10 cell lines were divided into myocardial cell group (group A), hypoxic myocardial cell group (group B), and hypoxic myocardial cell + transfection with lncRNA MEG3 mimic group (group C). The correlations of the adenosine triphosphate (ATP) concentration, the degree of apoptosis, and the proliferation with FoxO1 and FoxO3a proteins in the cells were observed via ATP assay, Cell Counting Kit-8 (CCK-8) assay, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, Western blotting, and quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR), respectively. RESULTS The ATP concentration in myocardial cells was the highest in group A (p<0.05), and it was higher in group B than that in group C (p<0.05). The results of the CCK-8 assay showed that the proliferation rate of the myocardial cells was the highest in group A and the lowest in group C (p<0.05), and it was significantly increased in group B compared with that in group C (p<0.05). The results of the TUNEL assay revealed that the normal cells displayed the purple color, and apoptotic cells displayed the green color. The myocardial cells were arranged orderly, and the number of apoptotic cells was smaller in group A, the number of apoptotic cells was significantly larger in group B than that in group A, and it was the largest in group C (p<0.05). Moreover, the results of Western blotting manifested that the concentrations of FoxO1 and FoxO3 proteins in myocardial cells were the lowest in group A (p<0.05), and they were significantly higher in group C than those in group B (p<0.05). According to the results of qRT-PCR, the mRNA expressions of FoxO1 and FoxO3 in myocardial cells were the lowest in group A (p<0.05), and they were remarkably lower in group B than those in group C (p<0.05). CONCLUSIONS LncRNA MEG3 can increase the activity of FoxO1 to promote myocardial apoptosis in a hypoxic environment.

Abstract
Cosmological models in which dark matter consists of cold elementary particles predict that the dark halo population should extend to masses many orders of magnitude below those at which galaxies can form1-3. Here we report a cosmological simulation of the formation of present-day haloes over the full range of observed halo masses (20 orders of magnitude) when dark matter is assumed to be in the form of weakly interacting massive particles of mass approximately 100 gigaelectronvolts. The simulation has a full dynamic range of 30 orders of magnitude in mass and resolves the internal structure of hundreds of Earth-mass haloes in as much detail as it does for hundreds of rich galaxy clusters. We find that halo density profiles are universal over the entire mass range and are well described by simple two-parameter fitting formulae4,5. Halo mass and concentration are tightly related in a way that depends on cosmology and on the nature of the dark matter. For a fixed mass, the concentration is independent of the local environment for haloes less massive than those of typical galaxies. Haloes over the mass range of 10-3 to 1011 solar masses contribute about equally (per logarithmic interval) to the luminosity produced by dark matter annihilation, which we find to be smaller than all previous estimates by factors ranging up to one thousand3.

Abstract
BACKGROUND The relationship between cancer and venous thromboembolic disease (VTD) are complex because the activated coagulation factors are not only involved in thrombosis but also in malignant processes, such as angiogenesis and metastasis. OBJECTIVE To compare phenotypes of extracellular vesicles (EVs), and levels of D-dimer, soluble P-selectin (sP-selectin) and antigenic tissue factor (TF) between unprovoked VTD patients, who did not develop cancer during one-year follow-up, and those with advanced stage of cancer but not associated with VTD. METHODS A prospective study in which we included 138 unprovoked VTD patients and 67 advanced cancer patients, who did not develop thrombosis. Levels of EVs of different cellular origin (platelet, endothelium and leukocyte), EVs positive for tissue factor (TF) and P-selectin glycoprotein ligand 1 were quantified by flow cytometry. D-dimer, soluble P-selectin (sP-selectin) and antigenic TF were determined by ELISA. RESULTS TF-positive EVs, D-dimer, and sP-selectin were markedly elevated in unprovoked VTD patients compared to cancer patients without association with thrombosis. CONCLUSIONS Levels of TF-positive EVs, D-dimer and sP-selectin are able to discriminate between unprovoked VTD patients not related to cancer and cancer patients not associated with VTD. These results could lead to the application of EVs as biomarkers of both diseases. Key messages: Circulating EVs, specifically TF-positive EVs, in combination with plasmatic markers of hypercoagulable states, such as D-dimer, sP-selectin and antigen TF, are able to discriminate between cancer patients without thrombosis and patients with unprovoked VTD. Research fields could be opened. Future studies will assess if these biomarkers together serve as predicting thrombotic events in cancer populations.

Abstract
PURPOSE The clinical outcome after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is diverse in infertility patients with polycystic ovary syndrome (PCOS). The aim of this study was to develop a nomogram based on an association of patients' characteristics to predict the live birth rate in PCOS patients. METHODS All women in a public university hospital who attempted to conceive by IVF/ICSI for PCOS infertility from January 2014 to October 2018 were included. The nomogram was built from a training cohort of 178 consecutive patients and tested on an independent validation cohort of 81 patients. PCOS was confirmed in all participants. RESULTS Three variates significantly associated with live birth rate of PCOS patients were BMI, total serum cholesterol (TC) and basal FSH. This predictive model built on the basis of BMI, TC, basal FSH, type of embryo transferred and age showed good calibration and discriminatory abilities, with an area under the curve (AUC) of 0.708 (95% CI 0.632-0.785) for the training cohort. The nomogram showed satisfactory goodness-of-fit and discrimination abilities in the independent validation cohort, with an AUC of 0.686 (95% CI 0.556-0.815). CONCLUSION Our simple evidence-based nomogram presents graphically risk factors and prognostic models for IVF/ICSI outcomes in patients with PCOS, which can offer useful guidance to clinicians and patients for individual adjuvant therapy.

Abstract
BACKGROUND Thyroid-stimulating hormone (TSH) plays an important role in the regulation of lipid metabolism. However, little is known about the role that exosomes play in the process of TSH-induced lipotoxicity in non-alcoholic fatty liver disease (NAFLD). As a preliminary step, the present study set out to investigate alterations in protein expression in exosomes derived from TSH-stimulated HepG2 cells. METHODS HepG2 cells were treated with TSH, exosomes were collected, and proteins were identified by mass spectrometry (MS). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway analysis were performed to analyze the identified proteins. RESULTS TSH treatment significantly increased exosomal production and changed the exosomal proteomic profile in HepG2 cells. Among the 1728 proteins, 140 identified proteins were upregulated and seven proteins were downregulated. GO analysis and KEGG analysis revealed that these proteins were involved in multiple processes including metabolism, apoptosis, and inflammation. CONCLUSION Our preliminary study demonstrated that exosomes derived from TSH-stimulated hepatocytes were increased and showed a specific altered spectrum of proteins, many of which were involved in metabolism, signal transduction, apoptosis, and inflammation. This study offers new insights into the pathogenesis of TSH-induced lipotoxicity in NAFLD.

Abstract
Intrinsically photosensitive retinal ganglion cells (ipRGCs) are atypical photoreceptors that are different from classical cone and rod cells. The primary role of ipRGCs is to signal light for largely subconscious, non-image vision such as photoentrainment of circadian rhythm and pupillary light reflex. Recent researches have revealed additional roles for ipRGCs in communication with synapses around, conscious vision reception and pathogenesis of some diseases. Here we review the research advances of morphology, functions and clinical applications of ipRGCs. (Chin J Ophthalmol, 2020, 56: 308-312).

Abstract
The topological magnetoelectric effect is associated with the photonic spin-orbit interaction. However, due to the proportionate fine structure constant of the topological term, the topological magnetoelectric effect is usually weak. In this paper, we demonstrate that the axion term enables manipulation of the spin Hall shift of light around Fano resonance. And, the excited surface plasmon near the nanoparticle's interface could enhance the topological magnetoelectric effect for several orders. Numerical simulation of near field and far-field scattering confirms our theoretical results. Our work may pave the way to exploit the topological magnetoelectric effect in practical applications, such as optical sensing and nanoprobing.

Abstract
PURPOSE OF REVIEW Maternal hypertension is a common and serious condition associated with increased maternal and foetal morbidity and mortality, with early detection and management improving outcomes. RECENT FINDINGS Blood pressure (BP) changes of pre-eclampsia are defined after 20 gestational weeks, while haemodynamic changes can be detected at 5-11 weeks using a specialised non-invasive Doppler stroke volume (SV) monitor. Thus, advanced haemodynamic monitoring allows for physiologically precise identification of circulatory abnormalities, and implementation of appropriate therapy within the first trimester. We measured the oscillometric BP and advanced haemodynamics (USCOM 1A) of 3 unselected women with singleton pregnancies, consecutively listed for therapeutic induction for maternal hypertension at 32-41 weeks gestational age. While the BP's of the patients varied, it was the haemodynamics, particularly SV, cardiac output, systemic vascular resistance, Smith Madigan Inotropy Index, and oxygen deliver, that identified differing patterns of circulatory dysfunction, therapeutic objectives, and predicted post-partum complications of the mother and child. First trimester screening of maternal haemodynamics may allow for earlier detection of circulatory derangements, selection of patient precise interventions, and improved maternal-foetal outcomes.

Abstract
Objective: The objective of the study was systematically summarized the current status of the hepatocellular carcinoma (HCC) screening guidelines, and evaluated the HCC screening guidelines according to the authoritative framework of cancer screening guidelines of authoritative institutions, which provided important value for the formulation of HCC screening evidence-based guidelines. Methods: Literature search was conducted in multiple databases from their inception dates to January 3, 2019. In addition, we sought relevant websites further was searched to identify potentially eligible studies. Two reviewers independently screened literature and extracted data. Qualitative description of the basic information, recommendations of HCC screening, source of evidence and update progress of the HCC screening guidelines was conducted. Results: At present, there were no independent HCC screening guidelines worldwide. There were only 17 clinical practice HCC guidelines briefly provided the recommendation of HCC screening. Current HCC screening guidelines only recommended screening for high-risk groups of HCC. All guidelines have identified patients with chronic hepatitis B, hepatitis C and cirrhosis as high-risk groups for HCC. Most of guidelines recommended screening intervals was 6 months. The latest guidelines in Europe and the United States recommended ultrasound for screening HCC. The combination of ultrasound and AFP was recommended in the Asian guidelines. Currently, HCC screening guidelines mainly recommended screening strategies based on factors such as risk of HCC, accuracy of screening modality, screening cost, etc.. The key factors such as screening efficacy and safety have not yet been considered comprehensively. Conclusions: There were no independent HCC screening guidelines worldwide. Only some clinical practice HCC guidelines briefly mentioned HCC screening. Currently, the guidelines only recommend screening for high-risk groups of HCC, with a screening interval of 6 months. There are differences in screening modalities recommended by European, American and Asian guidelines for screening HCC. It is suggested that the relevant institutions should formulate the evidence-based HCC screening guidelines by referring to the theoretical framework of other authoritative other cancer screening guidelines.

Abstract
Immune checkpoint inhibitor (ICI) has been emerged as a major breakthrough in tumor immunotherapy, but its unique mechanism of action has also led to a number of immune-related adverse events (irAE). Type 1 diabetes mellitus (T1DM) is one of the rarest irAEs. This paper reports a case of advanced malignant liver tumor-induced T1DM who received second-line anti-PD-1 therapy and showed initial symptoms of hyperosmolar coma and hyperglycemia. In addition, the relevant literature at home and abroad was collected and reviewed, and the clinical characteristics of T1DM induced by anti-PD-1 therapy were summarized with a view to achieve early detection, diagnosis and treatment.

Abstract
We theoretically study the optical bistability and tristability in plasmonic coated nanospheres containing the nonlinear plasmonic shell and the dielectric core with radial anisotropy. Based on self-consistent mean-field approximation, we establish the relationship between the local field in the shell and the applied incident field, taking into account the Lorentz local field. One or two optical bistabilities and even optical tristability can be observed. Especially, there are two critical geometric parameters between which two optical bistabilities exist. Physically, two optical bistablities result from the excitations of two surface plasmonic resonant modes in the inner and outer interfaces of coated nanospheres, which are well reflected from the spectral representation with two poles. Moreover, the involvement of the radial anisotropy is quite essential to realize the optical tristability. Further discussion on the field-induced tuning of the reflectance reveals the macroscopic properties of this nonlinear optical structure, which provides a potential candidate for designing multi-stable optical devices at the nanoscale.

Abstract
Background:In patients with primary Sjögren’s syndrome (pSS), both minor and major salivary glands are targets of the disease. Infiltration of salivary glands by immune cells is characteristic for pSS. However, significant inter- and intra-individual variation exists in the size and composition of the infiltrates. Potential differences between minor and major salivary glands in immune cell presence and inflammatory pathway activation are unclear. This knowledge is essential for clinical trial design and precision therapy.Objectives:To compare the transcriptome of paired labial and parotid salivary gland tissue of patients with pSS and non-SS sicca controls.Methods:Thirty-nine pSS patients and 20 age- and sex-matched non-SS sicca controls, who participated in a prospective diagnostic cohort[1], were included. All pSS patients fulfilled 2016 ACR-EULAR criteria. RNA was isolated from formalin-fixed, paraffin-embedded labial and parotid gland tissue sections from the same individuals. Complementary DNA libraries were prepared and sequenced. Biopsies with evidence of sclerosing chronic sialoadenitis or mucosa-associated lymphoid tissue lymphoma were excluded in the current analysis. For differential gene expression analysis, patients were subdivided in four categories: I) non-SS sicca without lymphocytic infiltration, II) non-SS sicca with aspecific infiltration, III) pSS with negative biopsy (focus score<1), IV) pSS with positive biopsy (focus score≥1). For each differentially expressed gene (DEG), a false detection rate (FDR) was calculated. FDR<0.05 was considered significant.Results:Principal component analysis (PCA) showed that only pSS patients with a positive biopsy (group IV) could be separated from the non-SS sicca patients based on gene expression. When comparing the labial and parotid gland transcriptome, resp. 798 and 1461 DEGs (FDR-adjusted p-value<0.05, log2 fold change >1) were identified between groups I and IV. The top differentially regulated genes were mostly related to T and B cells.CXCL13, CCR6, MS4A1(CD20), FCRL4andDAZLwere among the genes with the highest positive fold change in both glands of biopsy-positive pSS patients. Overall, there was a moderate to strong correlation between fold changes in labial and parotid glands (R2=0.58, p-value<0.0001). Between biopsy-negative and biopsy-positive pSS (groups III and IV), 226 and 962 DEGs were identified for labial and parotid gland tissue, respectively. Interestingly, we could not identify DEGs between biopsy-negative pSS (group III) and non-SS sicca patients (group I).Conclusion:The transcriptome of labial and parotid gland tissue from pSS patients with a positive biopsy is overall comparable, while salivary gland tissue from biopsy-negative pSS patients shows a comparable gene expression profile to non-SS sicca controls. These results indicate that different treatment strategies may be necessary for biopsy-negative and biopsy-positive pSS patients.References:[1]van Nimwegen JF,et al.Validation of the ACR-EULAR criteria for primary Sjögren’s syndrome in a Dutch prospective diagnostic cohort.Rheumatology (Oxford) 2018;57:818–25.Disclosure of Interests:Gwenny M.

Abstract
Abstract
Introduction
Daytime napping is common in elderly adults and has been associated with cognitive impairment. Prior studies have assessed napping at one time point, making it difficult to examine the longitudinal progression of napping and its association with cognitive aging. We examined objectively measured daytime napping longitudinally across different stages of Alzheimer’s disease (AD): from no cognitive impairment (NCI), to mild cognitive impairment (MCI), and to Alzheimer’s dementia.
Methods
We studied 1,066 participants (female: 810; age: 81.0±7.3 [SD]) in the Rush Memory and Aging Project who have been followed for up to 13 years. Motor activities of up to 10 days were recorded annually and used to assess napping objectively. We defined daytime napping episodes as segments between 10AM and 7PM with continuous zero-activity for ≥10min but <1h (to avoid off-wrist periods). Segments that were <5min apart were merged. Cognitive and clinical evaluations were administered annually to render a clinical diagnostic classification of NCI, MCI, or Alzheimer’s dementia. To examine how napping duration and frequency change with the progression of AD, we performed linear mixed-effects models with 2 change points anchored at the diagnoses of MCI and AD while adjusted for age, sex, and education.
Results
At baseline, participants had 1.44±0.04 (mean±standard error) naps with an accumulated duration of 35.0±1.1 min per day. Napping duration increased by 5.2±0.3 min and frequency increased by 0.21±0.01 times every year (both p<0.0001). The rate of increase was more than doubled after MCI diagnosis with an annual increase of 11.4±0.7 min in duration and 0.40±0.02 times in frequency (both p<0.0001); these were doubled further after AD diagnosis with an annual change of 26.3±3.1 min in duration and 0.84±0.08 times in frequency (both p<0.0001).
Conclusion
Daytime napping duration and frequency increase with aging, and the increase was accelerated with AD progression.
