RESUMO

OBJECTIVE: To examine the epidemiology of sense of alienation (SoA) and its associations with depressive symptoms and poor sleep quality (PSQ) in Chinese older adults who experienced lockdown during the COVID-19 pandemic. BACKGROUND: There is a dearth of data on SoA in older adults during the COVID-19 pandemic. METHODS: Altogether, 543 community-dwelling older adults (50+ years) were recruited via the three-tier mental health network in Wuhan, China, and completed an online questionnaire in April 2020, the first month after the reopening of Wuhan. SoA, depressive symptoms, and sleep quality were measured by using the General Social Alienation Scale, Depression Anxiety and Stress Scale, and a single standardized question, respectively. RESULTS: The prevalence of SoA was 52.3% (95% confidence interval: 48.1-56.5%). Factors associated with higher levels of SoA were religious belief (ß = 1.960, P = .024), monthly family income<4000 RMB (ß = 1.405, P = .022), unemployment (ß = 1.217, P = .039), fair or poor physical health (ß = 2.202, P = .002), never and sometimes receiving community support (ß = 2.297, P < .001 and ß = 3.417, P < .001), perceiving a low possibility of a cure for COVID-19 (ß = 2.379, P < .001), and affirmative and unsure fear of COVID-19 patients (ß = 2.025, P = .007 and ß = 1.101, P = .027). After adjusting for sociodemographic and pandemic-related variables, a one-SD increment in the SoA score was significantly associated with depressive symptoms (Odd Ratio [OR] = 5.59, P < .001) and poor sleep quality (Odd Ratio = 2.00, P < .001). CONCLUSION: Over half of the older adults who experienced lockdown felt alienated, and SoA was independently associated with their depressive symptoms and PSQ. Efforts are warranted to address SoA in older adults who experienced lockdown during the pandemic.

RESUMO

BACKGROUND: Mental illness is a major burden of disease worldwide. Community Mental Health Services (CMHS) are key to achieving community-based recovery for people with mental illness. In China, even though the community management of patients with mental illness is improving, the barriers faced by Community Mental Health Workers (CMHWs) are unclear. This study explores the difficulties and challenges in CMHS from the perspective of CMHWs. The results of this study may provide a practical basis for the training of CMHWs. METHODS: We carried out a qualitative study using an empirical phenomenological approach. Nine CMHWs were recruited from nine communities in Wuhan, Hubei Province, using purposive and snowball sampling. Face to face semi-structured in-depth interviews were conducted with them from December 27 to 28, 2019. Interview recordings were converted to text content by Nvivo 11.0 software and analyzed using Colaizzi's phenomenological method. RESULTS: Three main themes were identified in this study: 1) Lack of role orientation leads to role ambiguity, 2) Failure to establish a therapeutic trust relationship with patients, and 3) Lack of communication and collaboration with various departments and peers. Seven sub themes were also identified. In these themes, CMHWs emphasized the importance of role clarity, therapeutic trusting relationships, and effective communication and coordination mechanisms. CONCLUSION: Although China has made great efforts on the road to improving the quality of CMHS, several salient issues regarding CMHWs must be addressed to optimize the quality of services provided by CMHWs. Community mental health institutions should help CMHWs overcome these difficulties, by maximizing its value and promoting the development of CMHS.

RESUMO

BACKGROUND: Loneliness is a significant public health concern among older adults (OA) given its association with a wide range of adverse health outcomes. Primary care is an opportune setting to manage loneliness. However, the epidemiology of loneliness in Chinese OA treated in primary care remains unclear. The present study investigated the prevalence and correlates of loneliness in OA treated in Chinese primary care. METHODS: A total of 744 OA patients (65+ years) were consecutively recruited from 13 primary care clinics in Wuhan, China, and interviewed with a standardized questionnaire, concerning sociodemographic characteristics, lifestyle, relationships with family and others, physical health, and sensory impairments. Consistent with prior research on the construct, loneliness was measured with a single-item self-report question. Logistic regression was used to identify correlates of loneliness. RESULTS: Of primary care OA patients, 26.2% endorsed loneliness. Factors significantly and independently associated with loneliness included 75+ age group (odds ratio [OR]: 1.61, 95% confidence interval [CI]: 1.07, 2.44, P: 0.023), being illiterate (OR: 2.07, 95%CI: 1.26, 3.42, P: 0.004), unmarried (OR: 2.30, 95%CI: 1.40, 3.78, P: 0.001), living alone (OR: 4.37, 95%CI: 2.27, 8.41, P < 0.001), having fair and poor family (OR: 2.44, 95%CI: 1.48, 4.00, P < 0.001) and non-family relationships (OR: 1.75, 95%CI: 1.10, 2.78, P: 0.019), and ≥2 chronic medical conditions (OR: 2.91, 95%CI: 1.22, 6.95, P: 0.016). CONCLUSIONS: Loneliness is common in Chinese primary care OA. The high prevalence and many negative health consequences of loneliness for OA highlight the importance of routine screening, assessment, and interventions to reduce loneliness in the primary health-care setting.

RESUMO

OBJECTIVE: To study long-term effect on renal function exposed to environmental cadmium. METHODS: Stratified random sampling and cluster sampling method of epidemiological investigations were carried out in northern Guangdong province between April, 2011 and August, 2012. A total of 167 residents who lived in high cadmium exposure area for more than 15 years, aged above 40 were selected in exposed group. Moreover, A total of 145 residents who had similar living and economic conditions and lived in local for more than 15 years, aged above 40 were selected in control group. We used health questionnaires and medical examinations in order to acquire their health status. Home-harvested rice and vegetables were collected using quartering method for detection of cadmium level. Urine specimens of residents were collected for detection of cadmium level and creatinine as well as renal dysfunction biomarkers, namely, N-acetyl-beta-D-glucosamidase (NAG), ß2-microglobulin (ß2-MG), and retinol binding protein(RBP), respectively. The analysis of spearman rank correlation and multiple regression were used to investigate the relationships between age, urinary cadmium levels and renal injury biomarkers. RESULTS: The cadmium levels in rice and vegetables of exposed group were 0.75 and 0.10 mg/kg, both were significantly higher than 0.07 and 0.01 mg/kg in the control group (Z values were -6.32 and -7.84, all P values < 0.001). The urinary cadmium level of exposed group was 8.29 µg/g · cr, which was higher than that of the control group 2.03 µg/g · cr with significant difference (Z value was -11.39, P < 0.001). After stratified the total population by age, the urinary cadmium level in 40-49 years, 50-59 years and ≥ 60 years subgroups were 7.22, 8.71, and 13.10 µg/g · cr, which both were significantly higher than 1.80, 2.04, and 2.05 µg/g · cr in the control group (Z values were -5.22, -7.41, and -7.14, all P values < 0.001). After stratified the total population by gender, the urinary cadmium level of male and female were 5.12 and 12.36 µg/g · cr, which both were significantly higher than 1.79 and 2.16 µg/g · cr in the control group (Z values were -7.68 and -9.03, all P values < 0.001). Comparing the differences of renal dysfunction biomarkers (NAG, ß2-MG, RBP) between two groups. The level of urinary ß2-MG and RBP of exposed group were 0.21 and 0.04 µg/g · cr, which were higher than 0.05 and 0.00 µg/g · cr of the control group with significant difference (Z value was -7.08 and -9.65, all P values < 0.001). Pearson correlation analysis showed that NAG, ß2-MG and RBP were positively correlated with urinary cadmium and age, the correlation coefficients were 0.57, 0.49, 0.21 and 0.22, 0.26, 0.23 respectively (all P values < 0.001). After adjusting the effect of age, it was appeared that urinary cadmium levels contributed most to the alteration of NAG, ß2-MG and RBP, the standardized regression coefficients were 0.57, 0.49 and 0.20 (all P values < 0.001), and suggested that the cadmium body burden was one of the most important factors for renal dysfunction. CONCLUSION: Residents, who had cadmium contaminated rice and vegetables for a long time, would take the risk of increasing body burden of cadmium and urinary early biomarkers of renal tubular injury that referred to occurrence of renal dysfunction.

RESUMO

Background: While the association between physical activity (PA) and depression has been established, there is limited research on the effect of PA on the risk of depression among Chinese individuals. Thus, this study aimed to investigate the relationship between PA and depression among Chinese individuals. Methods: We used a stratified random sampling approach to recruit participants from five urban districts in Wuhan, China. A total of 5,583 permanent residents aged 18 years or older completed questionnaires, which included the International Physical Activity Questionnaire Short Form (IPAQ-SF) to measure PA, and the 9-item Patient Health Questionnaire (PHQ-9) to evaluate depressive symptoms. To control for potential confounders, multiple logistic regression was employed to assess the association of PA with depression. Results: The depression group had significantly lower weekly PA levels, measured in metabolic equivalent of task-minutes per week (MET-min/w), compared to the non-depression group [1,770 (693-4,200) MET-min/w vs. 2,772 (1,324-4,893) MET-min/w, p < 0.001]. In the fully adjusted model, the moderate and high PA level groups had lower odds ratios (ORs) for depressive symptoms compared to the low PA level group [OR (95% confidence interval (CI)) = 0.670 (0.523-0.858), 0.618 (0.484-0.790), respectively]. Among males, moderate and high levels of PA were associated with lower risk of depression compared to low PA levels [OR (95% CI) = 0.417 (0.268-0.649), 0.381 (0.244-0.593), respectively]. However, this association was not observed in females [OR (95% CI) = 0.827 (0.610-1.121), 0.782 (0.579-1.056), respectively]. The study found a significant interaction between PA levels and gender in relation to depression (P for interaction = 0.019). Conclusion: The findings suggest a negative association between PA and risk of depressive symptoms, indicating that moderate to high levels of PA may serve as a protective factor against depressive symptoms.

RESUMO

Background: Polydrug abuse is common among opioid users. Individuals who use both heroin and methamphetamine (MA) have been shown to experience a wide range of cognitive deficits. Previous research shows that repetitive transcranial magnetic stimulation (rTMS) can change cerebral cortical excitability and regulate neurotransmitter concentration, which could improve cognitive function in drug addiction. However, the stimulation time, location, and possible mechanisms of rTMS are uncertain. Methods: 56 patients with polydrug use disorder were randomized to receive 20 sessions of 10 Hz rTMS (n = 19), iTBS (n = 19), or sham iTBS (n = 18) to the left DLPFC. All patients used MA and heroin concurrently. Cognitive function was assessed and several related proteins including EPI, GABA-Aα5, IL-10, etc. were quantified by ELISA before and after the treatment. Results: Baseline RBANS scores were lower than normal for age (77.25; IQR 71.5-85.5). After 20 treatment sessions, in the iTBS group, the RBANS score increased by 11.95 (95% CI 0.02-13.90, p = 0.05). In particular, there were improvements in memory and attention as well as social cognition. Following treatment, serum EPI and GABA-Aα5 were reduced and IL-10 was elevated. The improvement of immediate memory was negatively correlated with GABA-Aα5 (r = -0.646, p = 0.017), and attention was positively correlated with IL-10 (r = 0.610, p = 0.027). In the 10 Hz rTMS group, the improvement of the RBANS total score (80.21 ± 14.08 before vs.84.32 ± 13.80 after) and immediate memory (74.53 ± 16.65 before vs.77.53 ± 17.78 after) was statistically significant compared with the baseline (p < 0.05). However, compared with the iTBS group, the improvement was small and the difference was statistically significant. There was no statistically significant change in the sham group (78.00 ± 12.91 before vs.79.89 ± 10.92 after; p > 0.05). Conclusion: Intermittent theta burst stimulation to the left DLPFC may improve cognitive function in polydrug use disorder patients. Its efficacy appears to be better than that of 10 Hz rTMS. The improvement of cognitive function may be related to GABA-Aα5 and IL-10. Our findings preliminarily demonstrate the clinical value of iTBS to the DLPFC to augment neurocognitive recovery in polydrug use disorders.

RESUMO

Background: Attention deficit hyperactivity disorder (ADHD) is a common neurobehavioral disorder in childhood. Brain-derived neurotrophic factor (BDNF) is widely distributed in the central nervous system and plays an important role in neural development. Despite several previous studies have examined the association between the Val66Met polymorphism BDNF and ADHD, the results are conflicting. Objective: This study aimed to evaluate the association between Val66Met polymorphism and ADHD in case-control and transmission disequilibrium test (TDT) studies using a meta-analysis. Methods: Keywords "rs6265" or "Val66Met" and "Attention deficit hyperactivity disorder" were used to search in the PubMed, Embase, Web of Science, Wanfang, and China National Knowledge Infrastructure databases before April 2021. Genotype data were extracted to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results: Fifteen studies, comprising of 8,692 samples (containing 4,364 cases, 4,328 controls) and 1,578 families were included and results demonstrated that rs6265 was not associated with susceptibility to ADHD (OR = 0.95, 95% CI: 0.87-1.04, P = 0.291). Stratified analyses by study design, ethnicity, and sample size further supported that rs6265 was not associated with ADHD. Conclusion: The present study shows that the polymorphism of the BDNF Val66Met gene is not associated with susceptibility to ADHD.

RESUMO

BACKGROUND: In recent years, there has been increasing awareness on the importance of mental health services for persons with disability in China, but data on mental health of persons with speech disability (PwSD) are scarce. This study examined prevalence and correlates of major depressive disorder (MDD) among Chinese PwSD, as well as their perceived need for and utilization of mental health services. METHODS: A total of 227 community-residing adult PwSD were successfully recruited by using multi-stage sampling approach, and interviewed with the Mini-international Neuropsychiatric Interview 5.0. Depressed PwSD's perceived need for and utilization of mental health services were also measured. RESULTS: 29.5% of the PwSD suffered from MDD during the month before the interview and, of the depressed PwSD, 44.8% perceived a need for mental health care but only 1.5% had sought help from mental health specialists. Factors significantly associated with MDD included female gender (OR=2.42), marital status of "non-married" (OR=2.27), having the disability during childhood (OR=4.60) and adulthood (OR=10.99) (vs. at birth), co-occurring other types of disabilities (OR=2.29), major medical conditions (OR=2.62), and impaired ability of activities of daily living (OR=3.23). LIMITATIONS: Findings can only be generalized to PwSD who register with the Disabled People's Federation (DPF) in China, because the sampling frame was based on the registration system of DPF. CONCLUSIONS: There is a large unmet need for mental health services among Chinese PwSD. It is urgently needed to integrate the management of MDD and other common mental disorders into the services system for PwSD in China.

RESUMO

BACKGROUND: In recent years, there have been increasing calls for integrating late-life mental health services into primary care in China, but data on the epidemiology of depressive disorders in older adults receiving primary care are very limited. This study examined prevalence, correlates and recognition of depressive disorders among Chinese older adults receiving primary care. METHODS: A total of 752 older patients (65+ years) were consecutively recruited from 13 primary care clinics in Wuhan, China, and interviewed with the Chinese Mini-international Neuropsychiatric Interview 5.0. RESULTS: One-fifth (20.3%) of the older adults met DSM-IV criteria for depressive disorders during the month prior to the interview: 10.2% had major depression, 4.8% had dysthymia, and 5.3% had minor depressive disorder. The recognition rate of older patients with depressive disorders was 1.3% only. In multiple logistic regression analysis, factors significantly associated with depressive disorders included female gender (OR = 1.61), an education of primary school and below (OR = 1.69), poor financial status (OR = 2.44), poor or fair family relationship (OR = 1.66), loneliness (OR = 1.77), hypertension (OR = 1.91), heart disease (OR = 2.02), chronic gastric ulcer (OR = 6.01), and arthritis (OR = 3.55). LIMITATIONS: Older adults from primary care clinics of economically underdeveloped regions of China were not included. CONCLUSIONS: Depressive disorders are prevalent but poorly recognized in Chinese older adults receiving treatment in primary care clinics. In order to improve the emotional well-being and health of older adults, it is time to integrate the management of common mental disorders into primary healthcare in China.

RESUMO

BACKGROUND: Few systemic studies of psychotic depression (PD) have been conducted in first-episode and drug-naïve (FEDN) patients. This study was to examine the prevalence of PD and its clinical correlates in a large sample of FEDN outpatients with major depressive disorder (MDD) in a Chinese Han population, which to our best knowledge has not been studied. METHODS: In this cross-sectional study, a total of 1718 FEDN MDD outpatients were recruited. All patients were rated on the positive symptom subscale of the Positive and Negative Syndrome Scale (PANSS) for psychotic symptoms, the 17-item Hamilton Depression Rating Scale (HAMD-17) for depression and Hamilton Anxiety Rating Scale (HAMA) for anxiety. RESULTS: The prevalence of PD was 10.0% (171/1718) in MDD patients. Compared to the non-PD patients, PD patients had significantly older age, lower educational levels, higher anxiety symptom score and were more likely to attempt suicide. Further logistic regression analysis indicated that PD was associated with older age, suicide attempt and comorbid anxiety (all p < 0.05). Multiple regression analyses showed that both HAMD and HAMA total scores were significantly associated with PANSS positive symptom subscale score. LIMITATIONS: Our cross-sectional study design does not show a direct causal relationship between psychiatric symptoms and related factors in patients with MDD. CONCLUSIONS: Our results suggest a high prevalence of PD in MDD patients in the acute early stage in a Chinese Han population, which is associated with demographic variables and clinical symptoms.

RESUMO

Background: There is paucity of data regarding the prevalence and methods of deliberate self-harm (DSH) in patients with heroin dependence in international literature. In China, there have been a few studies investigating the prevalence of DSH in heroin-dependent patients (HDPs), but their rates varied widely. We thus conducted a meta-analysis of studies assessing the prevalence of DSH among Chinese HDPs. Methods: Relevant studies were retrieved from major Chinese databases (China National Knowledge Infrastructure, Wanfang data, and SinoMed) and western databases (PubMed, EMBASE, and PsycInfo). Two authors independently identified eligible studies and extracted data. Studies that included a representative sample of Chinese HDPs and ascertained DSH caseness in a reliable way were considered as high quality. Statistical analysis was performed using R software. Results: In total, 15 eligible studies with a total of 37,243 Chinese HDPs were included. All included studies were conducted in heroin detoxification settings. Only two studies were rated as high quality. The pooled prevalence of DSH in Chinese HDPs was 4.4% (95%CI: 2.9, 6.2%), but the heterogeneity of prevalence rates across studies was significant (I2 = 98%, P < 0.001). Studies rated as high quality had significantly higher prevalence of DSH than those rated as low quality (13.2 vs. 3.4%, P < 0.001). Swallowing foreign objects was the most common method of DSH, with a combined prevalence of 2.7% (95%CI: 1.6, 4.4%). Extreme DSH methods such as cutting off fingers and jumping from height were also not uncommon in this patient population. Conclusion: Due to methodological problems in available studies, we find a relatively low prevalence of DSH among Chinese HDPs receiving detoxification treatment. Nevertheless, the self-harmers of Chinese HDPs are more likely to harm themselves in a dangerous or life-threatening way. Restricting the availability of DSH methods may be an effective way to prevent or reduce DSH in China's detoxification treatment settings.

RESUMO

To date, no studies have examined loneliness in Chinese patients with substance use disorders. This study determined the prevalence and socio-demographic and clinical correlates of loneliness and its impact on quality of life (QOL) in Chinese heroin-dependent patients (HDPs) receiving methadone maintenance treatment (MMT). A total of 603 HDPs were consecutively recruited from three city-owned MMT clinics in Wuhan, China, and administered with a standardized questionnaire to collect socio-demographic and clinical data. Loneliness and QOL were assessed with a single-item self-report question and World Health Organization QOL Scale Brief Version, respectively. As high as 55.9% Chinese HDPs of MMT clinics endorsed loneliness. Multiple logistic regression found that non-married status, unemployment, religious beliefs, a history of injecting heroin, poor interpersonal relationship, and more depressive symptoms were significant contributors to loneliness. Lonely HDPs had significantly poorer physical and psychological QOL than not lonely HDPs. After controlling for the potential confounding effects of socio-demographic and clinical factors with analysis of covariance, these group-differences in physical (F = 127.169, P < 0.001) and psychological (F = 85.004, P < 0.001) QOL remained statistically significant. Loneliness is prevalent in HDPs receiving MMT and independently associated with poor QOL. To address this serious issue, psychosocial services, including the identification of psychosocial problems, expanded social supports that focus on promoting mental wellbeing, and, when necessary, psychiatric assessment and treatment, should be routinely provided in Chinese MMT settings.

RESUMO

Heroin users are at high risk for suicide. However, the epidemiological profile of suicidal behaviors in Chinese methadone-maintained patients remains largely unknown. This study determined the prevalence and correlates of suicidal ideation among Chinese methadone-maintained patients. A total of 603 methadone-maintained patients were consecutively recruited from three methadone maintenance treatment (MMT) clinics in Wuhan, China, and administered with standardized questionnaires to collect sociodemographic, clinical, and psychological data. Suicidal ideation was measured with a single self-report question "Have you ever thought about committing suicide?". Depression and anxiety were assessed with Zung's Self-rating Depression Scale and Zung's Self-rating Anxiety Scale, respectively. The one-month and lifetime prevalence rates of suicidal ideation were 17.9% and 58.9%, respectively. In multiple logistic regression, lifetime suicidal ideation was significantly associated with female (OR: 1.69), an educational attainment of primary school and below (OR: 1.47), fair and poor interpersonal relationship (OR: 2.20), a history of injecting heroin (OR: 1.60), depression (OR: 1.38), and anxiety (OR: 4.00). Methadone-maintained patients of MMT clinics have a high prevalence of suicidal ideation and therefore at high risk for suicide. Suicide prevention efforts at MMT clinics should include periodic evaluation of suicidality, psychosocial supports, and, when necessary, psychiatric treatment and crisis intervention.

RESUMO

To date there have been no studies investigating the characteristics of pain in Chinese heroin-dependent patients (HDPs) receiving methadone maintenance treatment (MMT). This study examined the frequency and socio-demographic and clinical correlates of pain in HDPs under MMT. A consecutive sample of 603 HDPs was recruited from three MMT clinics in Wuhan, China. These patients completed a standardized questionnaire concerning socio-demographic and clinical data. Pain intensity was assessed with the 5-point Verbal Rating Scale ("Overall, how intense is your pain now?") with responses of: 1 = none, 2 = mild, 3 = moderate, 4 = severe, 5 = very severe. A pain score of three or higher was used to denote clinical significant pain (CSP). The prevalence of CSP in HDPs receiving MMT was 53.6%. Factors significantly associated CSP in multiple logistics regression analysis were old age, marital status of "non-married", unemployment, having religious beliefs, a history of injecting heroin, a high dose of methadone, and more depressive symptoms. Over a half of Chinese HDPs receiving MMT have CSP. Services for HDPs in MMT settings should include periodic screening for pain, psychosocial supports, and professional treatment for pain.

RESUMO

Pain and cigarette smoking are very common in heroin-dependent patients (HDPs) receiving methadone maintenance treatment (MMT) and both have substantial negative effects on HDPs' physical and mental health. Nevertheless, very few studies have assessed the relationship between the two in HDPs. This study examined the association between pain intensity and smoking in Chinese methadone-maintained HDPs. A total of 603 HDPs were consecutively recruited from three MMT clinics in Wuhan, China, and administered with a socio-demographic and drug use questionnaire, a smoking questionnaire concerning average number of cigarettes smoked daily and Heaviness of Smoking Index, and Zung's Self-rating Depression Scale. We used a five-point Verbal Rating Scale to rate the intensity of pain. To determine whether pain's associations with smoking and nicotine dependence were independent, an analysis of covariance was adopted to control for the potential confounding effects of socio-demographic variables, drug use characteristics, and depressive symptoms. Net of potential confounders, in methadone-maintained HDPs, pain intensity was significantly higher in smoker than non-smokers (F = 11.836, P = 0.002) but the pain intensity did not differ significantly across patients with various levels of cigarette consumption (F = 1.992, P = 0.137), while the pain intensity significantly differed across patients with different levels of nicotine dependence (F = 3.252, P = 0.013). Pain is significantly associated with smoking in HDPs receiving MMT, this phenomenon may be explained by the association between nicotine dependence and pain.

RESUMO

The present study aimed to identify urine metabolites in women exposed to high cadmium (Cd) levels. Twenty-one women exposed to environmental Cd and 12 age-matched controls were categorized as high exposure (urine Cd ≥ 15 µg/g creatinine; n = 9) or low exposure (15 µg/g creatinine > urine Cd > 5 µg/g creatinine; n = 12). Low-molecular weight metabolites in urine were analyzed by gas chromatography and mass spectrometry after derivatization. An orthogonal partial least-squares discriminant analysis model was constructed, and metabolites from the dimensional model were selected according to the variable importance in projection (>1). Metabolites differing significantly in abundance between different exposure groups were identified by searching mass spectral databases, and related pathways were analyzed using the Kyoto Encyclopedia of Genes and Genomes. Approximately 110 significantly different metabolites were detected with variable importance in projection > 1, and 48 of them were found to differ markedly in abundance among the 3 groups. Twenty-seven matched with known metabolites, including 22 significantly increased and 5 markedly decreased in the high-exposure group (p < 0.01). Kyoto Encyclopedia of Genes and Genomes results indicated that carbohydrate, amino acid, bone, and intestinal flora metabolism and the tricarboxylic acid cycle were affected by Cd exposure. The present study identified metabolites that differed in abundance in response to Cd exposure. Further studies may connect these biomarkers to early damage caused by Cd.

RESUMO

OBJECTIVES: The aim of this study was to systematically evaluate the relationship between urinary excretion of cadmium (U-Cd) and biomarkers of renal dysfunction. METHODS: One hundred eighty five non-smoking female farmers (aged from 44 to 71 years) were recruited from two rural areas with different cadmium levels of exposure in southern China. Morning spot urine samples were collected for detecting U-Cd, urinary creatinine (U-cre), ß2-microglobulin (ß2-MG), α1-microglobulin (α1-MG), metallothionein (MT), retinol binding protein (RBP), albumin (AB), N-acetyl-ß-D-glucosaminidase (NAG), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT) and kidney injury molecule-1 (KIM-1). Spearman's rank correlation was carried out to assess pairwise bivariate associations between continuous variables. Three different models of multiple linear regression (the cre-corrected, un-corrected and cre-adjusted model) were used to model the dose-response relationships between U-Cd and nine urine markers. RESULTS: Spearman's rank correlation showed that NAG, ALP, RBP, ß2-MG and MT were significantly associated with U-Cd for both cre-corrected and observed data. Generally, NAG correlated best with U-Cd among the nine biomarkers studied, followed by ALP and MT. In the un-corrected model and cre-adjusted model, the regression coefficients and R² of nine biomarkers were larger than the corresponding values in the cre-corrected model, indicating that the use of observed data was better for investigating the relationship between biomarkers and U-Cd than cre-corrected data. CONCLUSIONS: Our results suggest that NAG, MT and ALP in urine were better biomarkers for long-term environmental cadmium exposure assessment among the nine biomarkers studied. Further, data without normalization with creatinine show better relationships between cadmium exposure and renal dysfunction.
