RESUMO
OBJECTIVE: To examine prevalence and correlates of insomnia symptoms in older Chinese adults (OCAs) during the COVID-19 outbreak. BACKGROUND: During the COVID-19 pandemic, insomnia is a major health concern of elderly individuals, but its subtypes have not been investigated. METHODS: Altogether, 590 OCAs (50+ years) were recruited via snowball sampling during the COVID-19 outbreak. Standardized self-report questions were used to assess the presence of difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), and early morning awakening (EMA). Classification tree analysis (CTA) was used to identify correlates of insomnia. RESULTS: The one-month prevalence (95% confidence interval) of any subtype of insomnia symptoms was 23.4% (20.0-26.8%), with DIS, DMS, and EMA being 15.4% (12.5-18.3%), 17.1% (14.1-20.2%), and 11.2% (8.64-13.7%), respectively. Worry about being infected with COVID-19 emerged as the most salient correlate of insomnia (P < .001); compared to participants who were not worried about being infected, those who were worried and very worried were 3.2-fold (24.3% vs 7.5%) and 5.5-fold (24.3% vs 7.5%) more likely to have insomnia, respectively. Among participants in the "very worried" branch, those residing in Wuhan were 1.8-fold more likely to have insomnia than those residing in other places (50.0% vs 27.5%, P = .011). Among participants in the "worried" branch, unemployed persons were 2.0-fold more likely to have insomnia than employed persons (37.0% vs 18.1%, P < .001). CONCLUSIONS: Insomnia symptoms were prevalent among OCAs during the COVID-19 outbreak. Selective intervention programs targeting elderly individuals who are worried about being infected, living in the epicenter of COVID-19, and unemployed might be effective.

OBJECTIVE: To estimate the prevalence of depressive symptoms (depression thereafter) and to identify the sociodemographic and clinical correlates of depression in a sample of elderly patients treated in the primary care setting in Wuhan, China. BACKGROUND: Primary care is an opportune setting for the management of late-life depression in China, but there have been no representative studies on the clinical epidemiology of depression in elderly Chinese primary care patients. METHODS: In total, 752 elderly patients (≥ 65 years) were consecutively recruited from 13 primary care centers in Wuhan, China, and interviewed with a standardized questionnaire. Depression was assessed with the 15-item Geriatric Depression Scale (GDS-15). RESULTS: Of the elderly Chinese primary care patients, 30.6% had depression (GDS-15 ≥ 5). Correlates of depression were an education level of primary school or less (odds ratio [OR]: 1.94, 95% confidence interval [CI]: 1.36-2.77, P < .001), poor financial status (OR: 2.19, 95% CI: 1.16-4.15, P = .016), lack of an exercise habit (OR: 1.40, 95% CI: 1.06-1.74, P = .023), 2 or more chronic medical conditions (OR: 1.90, 95% CI: 1.34-2.69, P < .001), and loneliness (OR: 3.53, 95% CI: 2.46-5.08, P < .001). CONCLUSIONS: Depression is prevalent among elderly Chinese primary care patients, indicating that elderly patients treated in primary care have a high level of need for mental health services in China. There is an urgent need to integrate mental health services into primary health care.

BACKGROUND: Mycophenolate mofetil (MMF) has been used to treat interstitial lung disease (ILD), but mycophenolate (MPA) pharmacokinetics was not reported for this use. This ancillary study of the EVER-ILD protocol aimed at describing the pharmacokinetic variability of MPA using population modelling in ILD. METHODS: Concentrations of MPA were measured during an 8-h course for 27 ILD patients treated with 1000 mg MMF b.i.d. Absorption, distribution and elimination of MPA were described using population compartment models with first-order transfer and elimination rate constants, while accounting for both absorption peaks using gamma absorption models. RESULTS: The pharmacokinetics of MPA was best described using a two-compartment model and two gamma absorption models, model performances of this model were still similar to those of a one gamma absorption model. This pharmacokinetics seemed to be notably influenced by body weight, renal function and inflammatory status. The distribubtion value area under the concentration curve between two administrations of MMF was AUC12 = 52.5 mg.h/L in median (interquartile range: 42.2-58.0 mg.h/L). CONCLUSION: This is the first study reporting MPA pharmacokinetics in ILD. This pharmacokinetics appears to be similar to other indications and should be further investigated in future studies.
RESUMO
There is little empirical data on the heightened risk of loneliness among individuals residing in the COVID-19 epicenter or those who have recently left. This study compared the risk of loneliness in individuals residing in Wuhan, the COVID-19 epicenter in China, and those who had recently left during the initial outbreak period to those living in non-epicenter regions. During the COVID-19 outbreak in China in 2020, three samples were obtained using snowball sampling. The samples included 2882 epicenter residents, 1028 left residents, and 2963 non-epicenter residents. Loneliness was assessed using the six-item De Jong Gierveld Loneliness Scale, with a score of two or more indicating the presence of loneliness. 53.5% and 55.2% of epicenter and recently left residents, respectively, experienced loneliness, which was significantly higher than the 43.9% observed in non-epicenter residents. After adjusting for covariates, the risk of loneliness remained statistically significant for both epicenter and left residents (OR = 1.35, P < 0.001 and OR = 1.20, P = 0.017, respectively), when compared to non-epicenter residents. Individuals residing in the COVID-19 epicenter, as well as those who have recently left, are at a heightened risk of loneliness during the outbreak. These individuals need psychosocial support to mitigate their risk of loneliness and promote their psychological wellbeing.

INTRODUCTION: Data on loneliness among older adults in China during the COVID-19 pandemic are still scarce. This study aimed to examine the prevalence of loneliness and identify its associated factors among older Chinese adults during the COVID-19 pandemic. METHODS: During the COVID-19 pandemic, 1268 older Chinese adults (aged 50+ years) were recruited through snowball sampling. The Chinese version of the validated six-item De Jong Gierveld Loneliness Scale was used to assess participants' recent feelings of loneliness, and a cut-off score of two or more was used to indicate the presence of loneliness. RESULTS: Loneliness was experienced by 37.9% of the participants in recent days. Factors significantly associated with loneliness included male sex (vs. female, OR: 1.62, p < .001), an education level of middle school and below (vs. college and above, OR: 1.50, p = .007), residing in the COVID-19 epicenter (vs. other provinces, OR: 1.48, p = .004), concern about contracting COVID-19 (OR: 1.68, p = .001), poor knowledge of COVID-19 (OR: 2.39, p = .012), and physical health problems (OR: 1.65, p < .001). DISCUSSION: Loneliness is common among older Chinese adults amid the COVID-19 pandemic. Targeted intervention programs may be more effective in reducing loneliness among older adults who are worried about contracting COVID-19, have poor COVID-19 knowledge, and experience physical health problems.

BACKGROUND: The feasibility and efficacy of low-protein diets (LPD) treatment in chronic kidney disease (CKD) is controversial. Based on the characteristics of the Chinese diet, we observe the qualification rates and short-term clinical effects of LPD for CKD patients in our center. METHODS: This is a retrospective cohort study. CKD stages 3-5 patients who were regularly followed up 5 times (over 2 years) and treated with LPD were included. We collected clinical data to observe the changes in LPD qualification rates and divided patients into LPD and non-LPD group according to the average dietary protein intake (DPI) of 5 follow-up time points and compared the changes in primary and secondary outcome measures between the two groups. RESULTS: We analyzed data from 161 eligible CKD stages 3-5 patients. From baseline to the 5th follow-up time point, the LPD qualification rates of all patients were 11.80%, 35.40%, 47.82%, 53.43% and 54.04%, respectively. For primary outcome measures, the urine protein/creatinine ratio (UPCR) decreased more in the LPD group than in the non-LPD group [Median (interquartile range, IQR) of the difference between the 5th follow-up time point and baseline: 0.19 (- 0.01-0.73) vs. 0.10 (- 0.08-0.27), P < 0.001]. We constructed three classes of mixed linear models (model I, II, III). The UPCR slopes were all negative in the LPD group and positive in the non-LPD group (P < 0.001). Meanwhile, in model I, the estimate glomerular filtration rate(eGFR) decline slope in the LPD group was lower than that in the non-LPD group [slope (standard error): - 1.32 (0.37) vs. - 2.35 (0.33), P = 0.036]. For secondary outcome measures, body mass index (BMI) triglycerides (TG), body weight, and fat free mass (FFM) showed stable statistical differences in the comparison of LPD and non-LPD groups, with greater declines in the former. CONCLUSION: The results of this study suggest that LPD treatment can reduce UPCR in patients with CKD stages 3-5, and may also delay the decline in eGFR. Meanwhile, it also reduces BMI, TG, body weight, and FFM, thus the need to prevent malnutrition in clinical implementation.

Background: Integrating mental health services into primary care is a potentially cost-effective way to decrease the treatment gap for anxiety in older adults but data on the epidemiology of anxiety symptoms in older Chinese adults in primary care settings have been very limited. This study investigated the prevalence and correlates of anxiety symptoms in Chinese older primary care patients. Methods: A total of 753 older primary care patients (≥65 years) were consecutively recruited from 13 primary care clinics in Wuhan, China, and interviewed with the validated Chinese version of the short form of the Geriatric Anxiety Inventory (GAI-SF). Results: The prevalence of anxiety symptoms (GAI-SF ≥ 3) in older primary care patients was 21.1%. Statistically significant correlates of anxiety symptoms were female sex (vs. male, OR = 1.85, P = 0.002), poor economic status (vs. good, OR = 2.31, P = 0.013), fair and poor family relationship (vs. good, OR = 1.85, P = 0.006), hypertension (OR = 2.01, P < 0.001), chronic gastric ulcer (OR = 6.82, P < 0.001), and Parkinson's disease (OR = 7.83, P = 0.031). Conclusions: Anxiety symptoms are prevalent among older adults attending primary care clinics. Efforts for preventing or reducing anxiety symptoms in older primary care patients may be more useful to target those who are women, have poor financial status, don't have a good family relationship, suffer from hypertension, have chronic gastric ulcer, and suffer from Parkinson's disease.

Background: Facial emotion identification (FEI) deficits are associated with impaired social functioning in persons living with schizophrenia (PLwS), but the research on emotion-specific FEI deficits remains inconclusive. Furthermore, existing studies on FEI deficits are limited by their small sample sizes. We performed a meta-analysis of studies comparing the FEI abilities between Chinese PLwS and healthy controls in terms of the six basic facial emotions (happiness, sadness, fear, disgust, anger, and surprise), as well as contempt, calmness, and neutral facial expressions. Methods: Major Chinese- and English-language databases were searched to retrieve case-control studies that compared the FEI task performance between Chinese PLwS and healthy controls (HCs) and reported the emotion-specific correct identification scores for PLwS and HCs. The Joanna Briggs Institute Critical Appraisal Checklist for Case-control Studies ("JBI checklist," hereafter) was used to assess the risk of bias (RoB) of the included studies. Statistical analysis was performed using the "meta" package of R 4.1.2. Results: Twenty-three studies with a total of 28 case-control cohorts and 1,894 PLwS and 1,267 HCs were included. The RoB scores of the included studies ranged from two to seven. PLwS had statistically significantly lower FEI scores than HCs and the corresponding emotion-specific pooled standard mean differences (95% confidence intervals) were -0.69 (-0.88, -0.50) for happiness, -0.88 (-1.12, -0.63) for sadness, -1.44 (-1.83, -1.06) for fear, -1.18 (-1.60, -0.76) for disgust, -0.91 (-1.24, -0.57) for anger, -1.09 (-1.39, -0.78) for surprise, -0.26 (-0.51, -0.01) for contempt, -0.31 (-0.52, -0.09) for calmness, and -0.42 (-0.65, -0.18) for neutral. In the analyses of sources of heterogeneity, drug-naïve status, clinical setting, positive and negative psychotic symptoms, and RoB were significant moderators of the magnitudes of FEI deficits. Conclusions: Chinese PLwS have significant FEI impairments in terms of recognizing the six basic facial emotions, contempt, calmness, and neutral emotions, and the magnitude of impairment varies depending on the type of emotion, clinical characteristics, and the level of RoB of the study. It is necessary to consider the characteristics of FEI deficits and the clinical moderators in the FEI deficits to develop remediation strategies targeting FEI deficits in schizophrenia.
RESUMO
Background: Although there has been accumulating evidence on the elevated risk of depression in hypertensive patients, data regarding depressive disorders in older adults with hypertension and the interplay between factors associated with depression in this population are very limited. Disentangling the mutual influences between factors may help illuminate the pathways involved in the pathogenesis of the comorbidity of depression in hypertension. This study investigated the prevalence of depressive disorders in older Chinese adults with hypertension and examined major correlates of depressive disorders and the interactions between correlates by using classification tree analysis (CTA). Methods: In total, 374 older adults with essential hypertension were enrolled from seven urban and six rural primary care centers in Wuhan, China, and interviewed with the Chinese Mini-international Neuropsychiatric Interview 5.0. Family relationship and feelings of loneliness were assessed with standardized questions. A checklist was used to assess the presence of six major medical conditions: diabetes mellitus, heart disease, cerebrovascular disease, chronic obstructive pulmonary disease, chronic gastric ulcer, and arthritis. Results: The 1-month prevalence rate of depressive disorders was 25.7%. The CTA model identified four major correlates of depressive disorders: loneliness was the most salient, followed by arthritis, family relationship, and heart disease. There were statistically significant interactions between loneliness and arthritis, loneliness and family relationship, and arthritis and heart disease. Conclusion: Over one out of every four older Chinese adults with hypertension suffer from depressive disorders. Collaborative multidisciplinary management services are needed to reduce the burden of depression in hypertensive older adults, which may include social work outreach services to promote family relationship, mental health services to relive loneliness, and primary care services to manage arthritis and heart disease.
RESUMO
Objective: Mental health services have been recognized as an essential part of the comprehensive eye care services, but data regarding the mental health of people living with vision disability (PLwVD) remain very limited. This study examined the epidemiology of major depressive disorder (MDD) among Chinese PLwVD, as well as their perceived needs for and utilization of mental health services. Methods: By using stratified cluster sampling method, a total of 1,753 PLwVD were successfully recruited from 73 urban communities and 169 rural villages in Wuhan, China, and interviewed with the Mini-international Neuropsychiatric Interview 5.0. Standardized questions were used to measure perceived mental healthcare needs and use of mental health services of PLwVD with MDD. Results: The one-month prevalence of MDD was 24.4%. Among the PLwVD with MDD, 26.0% perceived needs for mental healthcare and only 1.2% sought treatment from mental health specialists for their emotional problems. Factors associated with MDD were middle age [vs. young adulthood, odds ratio (OR) = 1.96, P < 0.001], older adulthood (vs. young adulthood, OR = 1.79, P = 0.004), being never-married (vs. married, remarried, and cohabiting, OR = 1.96, P < 0.001), being separated, divorced, and widowed (vs. married, remarried, and cohabiting, OR = 12.30, P < 0.001), a low level of objective social support (vs. high, OR = 1.83, P < 0.001), currently drinking (OR = 1.81, P < 0.001), having childhood-onset eye conditions (OR = 1.89, P = 0.005), and having difficulties in performing daily activities (OR = 2.78, P < 0.001). Conclusions: Chinese PLwVD are at high risk for MDD and have a high level of unmet need for mental healthcare. Public strategies are warranted to improve the mental health literacy of PLwVD and make the mental health services available, accessible, and affordable for PLwVD.

BACKGROUND: Bullying victimization has been associated with depressive symptoms in Chinese university students. This study examined the moderating effect of possible avoidant personality disorder (APD) on association between bullying victimization and depressive symptoms in university freshmen. METHODS: A total of 1,453 freshmen were recruited from a comprehensive university in Wuhan, China, and administered a self-report questionnaire. The APD subscale of Personality Diagnostic Questionnaire-Version 4 and Beck Depression Inventory were used to measure the presence of possible APD and depressive symptoms, respectively. The moderating effect of possible APD was examined by testing the statistical significance of the interaction between victimization and possible APD in multiple logistic regression analysis. RESULTS: The prevalence of depressive symptoms was 24.8%. In multiple logistic regression analysis, the interaction between bullying victimization and possible APD was significantly associated with depressive symptoms (OR: 1.80, P = 0.029). Subsequent subgroup analyses according to the status of possible APD showed that, the victimization-depression association was stronger among freshmen with possible APD (OR: 3.23, P < 0.001) than those without possible APD (OR: 1.82, P = 0.001). CONCLUSION: In Chinese university freshmen, bullying victimization is significantly associated with depressive symptoms, and possible APD magnifies the victimization-depression association. Bullied freshmen, particularly freshmen with possible APD, could be considered as the target group of campus-based depression intervention programs.
RESUMO
Background: Integrating the management of dementia into primary healthcare is a cost-effective way to reduce the burden of dementia but the clinical epidemiology of dementia in primary healthcare settings remains unclear. This study investigated the prevalence and correlates of suspected dementia in Chinese older adults receiving primary healthcare. Methods: In this multicenter cross-sectional survey, a total of 773 older adults (≥65 years) were consecutively recruited from seven urban and six rural primary care clinics in Wuhan, China, and interviewed with the validated Chinese version of the Brief Community Screening Instrument for Dementia (BCSI-D). Participants with suspected dementia were those who were screened positive on the BCSI-D. Results: The prevalence of suspected dementia in older primary healthcare adults was 26.8%. Factors significantly associated with suspected dementia were female sex (OR = 1.95, P < 0.001), age-group of 75+ (OR = 1.68, P = 0.004), poor financial status (OR = 4.79, P < 0.001), rural residence (OR = 1.47, P = 0.032), no regular physical exercise (OR = 1.74, P = 0.002), and stroke and other cerebrovascular diseases (OR = 1.97, P = 0.015). Conclusions: Chinese older adults receiving primary healthcare are at high risk of suspected dementia. Screening and intervention efforts for dementia in primary healthcare settings may be more useful to target older adults who are women, are 75 years and above, have poor economic status, are rural residents, have no exercise habit, and suffer from cerebrovascular diseases.

Background and objectives: Integrating sleep health into primary care is a promising approach to narrow the treatment gap for insomnia in older adults but data regarding the epidemiological characteristics of insomnia among elderly primary care attenders (EPCAs) are very limited. This study examined the prevalence and correlates of clinical insomnia among Chinese EPCAs. Methods: By using two-stage consecutive sampling method, a total of 757 EPCAs were recruited from seven urban and six rural primary care centers in Wuhan, China. The Insomnia Severity Index (ISI) and the Geriatric Depression Scale (15 item version) were administered to assess insomnia severity and depressive symptoms, respectively. Results: The two-week prevalence of clinical insomnia (ISI score ≥ 15) was 28.9%. Significant correlates of clinical insomnia were: female sex (vs. male, OR = 2.13, P < 0.001), fair and poor family relationship (vs. good, OR = 1.59, P = 0.028), hypertension (OR = 1.67, P = 0.004), heart disease (OR = 1.73, P = 0.048), arthritis (OR = 2.72, P = 0.001), and depressive symptoms (OR = 4.53, P < 0.001). Conclusion: The high prevalence of clinical insomnia among Chinese EPCAs suggests a high level of sleep health need in older patients in China's primary care settings. Considering the many negative outcomes associated with insomnia, it is necessary to integrate sleep health into primary care in China.

Background: Primary care represents an ideal setting for screening for and managing suicidal older adults but the clinical epidemiology of suicidal ideation in Chinese older primary care patients remains unclear. This study investigated the prevalence and correlates of suicidal ideation in older Chinese adults receiving primary care. Methods: This multicenter cross-sectional survey included a total of 769 older adults (≥65 years) from seven urban and six rural primary care clinics in Wuhan, China. The presence of depressive symptoms and suicidal ideation was assessed with the Geriatric Depression Scale and a single-item question "In the past 12 months, did you think about ending your life?," respectively. Results: The 12-month prevalence of suicidal ideation in older primary care patients was 16.6%. Significant correlates of suicidal ideation were poor economic status (vs. good, OR = 2.80, P = 0.008), heart disease (OR = 2.48, P = 0.005), chronic gastric ulcer (OR = 3.55, P = 0.012), arthritis (OR = 2.10, P = 0.042), and depressive symptoms (OR = 11.29, P < 0.001). Conclusions: Suicidal ideation is common among older adults attending Chinese primary care clinics. It is necessary to integrate psychological crisis intervention into primary care to prevent late-life suicide.
RESUMO
We recently reported that intraperitoneal injection of 7,8-dihydroxyflavone (7,8-DHF), a brain-derived neurotrophic factor-mimicking small compound, could attenuate alcohol-related behaviors in a two-bottle choice ethanol consumption procedure (IA2BC) in rats via tropomyosin receptor kinase B in the ventral tegmental area (VTA), which is closely related to alcohol use disorder. However, the detailed mechanisms underlying the regulation of 7,8-DHF on alcohol drinking behavior remain elusive. In this study, we determined the role of nitric oxide (NO), a pleiotropic signaling molecule, in the VTA in the action of 7,8-DHF upon alcohol drinking behavior. Intermittent alcohol exposure led to the overexpression of NO in the VTA, especially 72 h after withdrawal from four weeks of ethanol exposure in IA2BC rats. A higher amount of alcohol intake was also found at the same time point, consistent with the overexpression of NO in the VTA. Microinjection of NG-Nitro-l-Arginine Methyl Ester, (NO synthase inhibitor) or 2-4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (NO scavenger) into the VTA inhibited alcohol intake, whereas application of S-Nitroso-N-acetyl-DL-penicillamine (SNAP, the NO donor) in the VTA further enhanced alcohol consumption in IA2BC rats. Interestingly, either 1H-[1,2,4]oxadiazolo[4,3,-a]quinoxalin-1-one (a sGC inhibitor) or KT5823 [a selective protein kinase G (PKG) inhibitor] blocked NO's enhancing effect on ethanol intake. Intraperitoneal injection of 7,8-DHF reduced the overexpression of NO; SNAP microinjected into the VTA reversed the inhibitory effects of 7,8-DHF on alcohol consumption. Our findings suggest that NO-cGMP-PKG might be involved in regulation of 7,8-DHF on alcohol consumption in IA2BC rats.

Understanding the psychiatric symptoms of COVID-19 could facilitate the clinical management of COVID-19 patients. However, the profile of psychiatric symptoms among COVID-19 patients has been understudied. We performed a meta-analysis of studies assessing psychiatric symptoms of COVID-19 and SARS patients and survivors by using the Symptom Checklist-90-Revised (SCL-90-R), an instrument covering a wide spectrum of psychiatric symptoms. Studies reporting SCL-90-R subscale scores among patients with and survivors of COVID-19 and SARS were retrieved from major English and Chinese literature databases. Patients' pooled SCL-90-R subscale scores were compared to the Chinese normative SCL-90-R data, and Cohen's d values were calculated to indicate the severity of psychiatric symptoms. The Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data was used to assess the quality of the included studies. The search yielded 25 Chinese studies with 1675 acute COVID-19 and 964 acute SARS patients, 30 COVID-19 and 552 SARS survivors during very early recovery (up to 1 month since discharge), 291 SARS survivors during early recovery (1-6 months after discharge), and 48 SARS survivors during late recovery (12 months after discharge). None of the included studies were rated as good quality. The ten SCL-90-R-defined psychiatric symptoms, which were of medium-to-severe severity (d = 0.68-3.01), were all exhibited in acute COVID-19 patients, and the severity of these symptoms decreased to mild-to-medium during very early recovery (d = 0.17-0.73). SARS patients presented eight psychiatric symptoms with mild-to-severe severity during the acute stage (d =0.43-1.88), and thereafter, the severity of symptoms decreased over the follow-up period. However, somatization (d = 0.30) and anxiety (d = 0.28) remained at mild levels during late recovery. A wide variety of severe psychiatric symptoms have been reported by acute COVID-19 patients, and these symptoms, despite decreasing in severity, persist in very early recovery. The changing trajectory observed with SARS suggests that psychiatric symptoms of COVID-19 may persist for a long time after discharge, and therefore, periodic monitoring of psychiatric symptoms, psychosocial support, and psychiatric treatment (when necessary) may be necessary for COVID-19 patients from the acute to convalescent stages.

Background: Childhood left-behind experience (LBE) has a long-term detrimental effect on the mental health of Chinese University students, but it remains unclear whether childhood LBE negatively impacts the quality of life (QOL) of University students and whether the LBE-QOL association differs between students of rural origin and students of urban origin. This study examined the LBE-QOL relationship and the interactive effect between LBE and place of origin on QOL among Chinese University freshmen. Methods: By using a two-stage random cluster sampling approach, a total of 5,033 freshmen were recruited from two comprehensive universities. The students completed an online, self-administered questionnaire that included sociodemographic variables, a 2-week physical morbidity assessment, and assessments of depressive symptoms, academic stress, and QOL. The Chinese six-item QOL scale was used to assess QOL. Multiple linear regression was used to test the independent LBE-QOL association and the interaction between LBE and place of origin. Results: Students with childhood LBE had significantly lower QOL scores than those without LBE (60.1 ± 13.1 vs. 64.3 ± 11.7, p < 0.001). After adjusting for the potential confounding effects of other sociodemographic variables, 2-week physical morbidity, depressive symptoms, and academic stress, childhood LBE was significantly associated with a lower QOL score (ß: -3.022, p < 0.001) and the LBE-place of origin interaction was still significantly associated with the QOL score (ß: -2.413, p < 0.001). Overall, compared to non-LBE, LBE was associated with a QOL score decrease of 5.93 among freshmen of urban origin and of 3.01 among freshmen of rural origin. Conclusion: In Chinese University freshmen, childhood LBE is independently associated with poor QOL, and the LBE-QOL association is greater among freshmen from urban backgrounds than among freshmen from rural backgrounds.
RESUMO
BACKGROUND: To transfer a paper-version Chinese and Western medication adherence scale for CKD into an electronic scale, and evaluate its validity, internal consistency and clinical implementation, and assess whether the transition is feasible in clinic. METHODS: We built an e-version Chinese and Western medication adherence scale based on the Wen-JuanXing platform. CKD subjects' responses were applied to test the scale's validity and internal consistency. We retested some of the participants two weeks later randomly. We also tested the clinical application. RESULTS: Of the 434 recruited patients, 228 responded. In exploratory factor analysis (EFA), the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy = 0.8 and Bartlett's approx. Chi-Square = 1340.0 (df = 105, p < 0.001). We extracted four common factors which could explain 61.47% of the variance. However, Item 15 "Have you changed a traditional Chinese medicine prescription yourself within the past month?" had factor loading = 0.3 and measure of sampling adequacy (MSA) = 0.5, meaning we could not enter it into the factor analysis. The internal consistency reliability for medication adherence was 0.9, with a Guttman split-half coefficient = 0.5 and a Spearman-Brown coefficient = 0.6. Cronbach's α was 0.9, 0.4 and 0.5 for the knowledge, belief and behavior domains, respectively. The correlation coefficient r of the test-retest reliability was -0.8 and was -0.8, 0.4, -0.3 in the knowledge, belief and behavior domains, respectively. Patients with comorbidities were more likely to respond. We detected no other significant differences in the clinical profiles between respondents and non-respondents. CONCLUSION: The e-version Chinese and Western medication adherence scales have undesirable construct validity and internal consistency. Thus, caution is needed in transitioning the paper-version scale into an e-version.
RESUMO
Alcohol use-associated disorders are highly comorbid with anxiety disorders; however, their mechanism remains unknown. The amygdala plays a central role in anxiety. We recently found that 7,8-dihydroxyflavone (7,8-DHF) significantly reduces withdrawal symptoms in a rat model of chronic intermittent alcohol (ethanol) exposure. This study aimed to determine the role of 7,8-DHF in regulating anxiety induced by chronic alcohol exposure and its associated underlying mechanism. Male C57BL/6J mice were exposed to chronic intermittent alcohol for 3 weeks followed by alcohol withdrawal for 12 h with or without 7,8-DHF administered intraperitoneally. All mice were tested using an open field test and elevated plus maze to assess anxiety-like behaviors. Synaptic activity and intrinsic excitability in basal and lateral amygdala (BLA) neurons were assessed using electrophysiological recordings. 7,8-DHF alleviated alcohol-induced anxiety-like behavior and attenuated alcohol-induced enhancement of activities in BLA pyramidal neurons. Furthermore, 7,8-DHF prevented alcohol withdrawal-evoked augmentation of glutamatergic transmission in the amygdala and had no effect on GABAergic transmission in the amygdala, as demonstrated by unaltered frequency and amplitude of spontaneous inhibitory postsynaptic currents. Microinjection of K252a, a tropomyosin-related kinase B (TrkB) antagonist, into the BLA blocked the effects of 7,8-DHF on anxiety-like behavior and neuronal activity in the BLA. Our findings suggest that 7,8-DHF alleviates alcohol-induced anxiety-like behavior induced by chronic alcohol exposure through regulation of glutamate transmission involving TrKB in the BLA.

OBJECTIVES: A questionnaire which provides desirable reliability and validity has been previously developed to assess the disease awareness of diagnosed chronic kidney disease (CKD) patients. However, conventional paper questionnaires often have disadvantages, including recall bias. To substantially improve this, we therefore aimed to explore the feasibility of developing a smartphone-based electronic version (e-version) based upon its original paper version and subsequently tested its validity, reliability, and applicability. METHODS: A pilot study was conducted at Guangdong Provincial Hospital of Chinese Medicine in Guangzhou, China, during August 2019. The e-version had identical content to the paper version and was adapted in terms of layout and assisted functions via the Wechat-incorporated Wen-Juan-Xing platform. Eligible patients with diagnosed CKD were invited to participate and were assigned the e-version. Randomly selected respondents received a test-retest of the same e-version 2 weeks after their first completion. In some instances, psychometric properties, including validity and reliability of the e-version, were examined. In others, its clinical application was also tested, which included comparisons among the clinical profiles of patients who had/had not responded to the questionnaire as well as patients with above or below average questionnaire scores. RESULTS: Of the 225 patients screened, 217 were enrolled to participate, with a response rate of 52.5%. Desirable reliability (Cronbachα = 0.962, ICC for total scores = 0.948), while good convergent validity (Cronbachα = 0.962) and low discriminant validity (one extracted component), of the e-version were detected. Performing inter-group comparisons highlighted statistical differences in terms of higher education level (z = -2.436, P = 0.015) and earlier CKD stages (z = -1.978, P = 0.048), with these patients often preferring to respond. No significant differences were detected in the clinical profiles between respondents who obtained an above or below average questionnaire score. CONCLUSION: The e-version is reliable but was not shown to be a valid approach. Audiences with higher education levels and less advanced disease condition may prefer to respond to the e-version. Adaptation of this e-questionnaire, from its original paper version, may not be a direct transition and meticulous modifications may be required during the transition process.
