An analysis of health-related quality of life in children and adolescents after parotidectomy based on patient-reported outcomes.

PURPOSE: To assess health-related quality of life (HRQoL) and its influencing factors in these pediatric patients undergoing parotidectomy. METHODS: This was a cross-sectional study that included 37 children and adolescents (≤ 19 years) with parotid gland tumors who were treated in Sichuan Cancer Hospital between January 2006 and November 2021. HRQoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30). The Wilcoxon rank sum test was used to analyze the factors influencing patients' HRQoL. RESULTS: 37 children and adolescents were included in the study, including 22 cases of benign tumors and 15 cases of malignant tumors. All patients underwent surgery, and some patients with malignant tumors received radiotherapy or chemotherapy. Malignancy, permanent facial palsy, and Frey syndrome were associated with worse HRQoL in children and adolescents with parotid gland tumors. Radiotherapy and no cervical lymph node dissection were associated with worse HRQoL in pediatric patients with malignancy. The surgical approach of parotid is not a factor influencing HRQoL. CONCLUSION: Factors associated with HRQoL in children and adolescents with parotid gland tumors include pathological types, permanent facial palsy, and Frey syndrome. In addition, factors affecting patients with malignancy include lateral lymph node dissection and radiotherapy.

Factors related to suicidal ideation of schizophrenia patients in China: a study based on decision tree and logistic regression model.

This study aimed to investigate the factors associated with suicidal ideation in schizophrenia patients in China using decision tree and logistic regression models. From October 2020 to March 2022, patients with schizophrenia were chosen from Chifeng Anding Hospital and Daqing Third Hospital in Heilongjiang Province. A total of 300 patients with schizophrenia who met the inclusion criteria were investigated by questionnaire. The questionnaire covered general data, suicidal ideation, childhood trauma, social support, depressive symptoms and psychological resilience. Logistic regression analysis revealed that childhood trauma and depressive symptoms were risk factors for suicidal ideation in schizophrenia (OR = 2.330, 95%CI: 1.177 ~ 4.614; OR = 10.619, 95%CI: 5.199 ~ 21.688), while psychological resilience was a protective factor for suicidal ideation in schizophrenia (OR = 0.173, 95%CI: 0.073 ~ 0.409). The results of the decision tree model analysis demonstrated that depressive symptoms, psychological resilience and childhood trauma were influential factors for suicidal ideation in patients with schizophrenia (p < 0.05). The area under the ROC for the logistic regression model and the decision tree model were 0.868 (95% CI: 0.821 ~ 0.916) and 0.863 (95% CI: 0.814 ~ 0.912) respectively, indicating excellent accuracy of the models. Meanwhile, the logistic regression model had a sensitivity of 0.834 and a specificity of 0.743 when the Youden index was at its maximum. The decision tree model had a sensitivity of 0.768 and a specificity of 0.8. Decision trees in combination with logistic regression models are of high value in the study of factors influencing suicidal ideation in schizophrenia patients.

Relationship between medication burden and medication experience in stable patients with schizophrenia: the mediating effect of medication belief.

BACKGROUND: Individuals with schizophrenia require prolonged antipsychotic medication treatment. But more than 50% of individuals with schizophrenia experience adverse medication experiences during their antipsychotic treatments. Such individuals often adjust or discontinue medication, leading to disease relapse and impaired social functioning. Psychiatric nurses should pay close attention to the medication experiences of individuals with schizophrenia. This research explore the relationship between medication burden and medication experience, as well as the mediating effect of medication belief in stable patients with schizophrenia. METHODS: A convenience sample of hospitalized stable patients with schizophrenia were selected from Daqing Third Hospital and Baiyupao Hospital from September 2023 to December 2023. A survey was conducted with them using a questionnaire consisting of general information questionnaire, The Subjective Well-being Under Neuroleptic Treatment Scale(SWN), The Living with Medicines Questionnaire(LMQ), Beliefs about Medicines Questionnaire-Specific (BMQ-Specific). Pearson correlation analysis was used to explore the correlation between LMQ, BMQ-Specific and SWN scores, and multiple linear regression analysis was used to explore the influencing factors of medication experience in patients with schizophrenia. AMOS 24.0 was used to construct the structural equation modeling(SEM), and the mediation effect of the SEM was tested using Bootstrap method. RESULTS: According to the sample size calculation requirements of structural equation model, a total of 300 samples were required in this study, and 400 effective questionnaires were actually collected in this study, which met the sample size requirements for constructing structural equation models. Bootstrap test showed that the mediation effect was significant. The total effect of medication burden on medication experience was significant (Z=-12.146, 95%CI (-0.577, -0.417), P < 0.001). The indirect effect of medication burden on medication experience, that is, the mediating effect of medication belief was significant (Z=-4.839, 95%CI (-0.217, -0.096), P < 0.001). The direct effect of medication burden on medication experience was significant (Z=-7.565, 95%CI (-0.437, -0.257), P < 0.001). This model belongs to partial mediation model. CONCLUSIONS: Psychiatric nurses can enhance the patients' medication experience by reducing medication burden and strengthening medication beliefs. Therefore, the results also provide theoretical references and decision-making foundations for psychiatric nursing professionals to develop appropriate management strategies for individuals with schizophrenia.

Oral frailty: a concept analysis.

BACKGROUND: Oral frailty has become a worldwide problem among older adults. Although researchers have conducted various studies on oral frailty, its definition remains controversial. PURPOSE: To clarify the concept of oral frailty. METHODS: Online databases PubMed, Web of Science, CINAHL, Cochrane Library, ProQuest, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang database were searched from inception to September 20, 2023. The reference lists of relevant studies were searched manually. Eligible articles, theses, and books were analyzed using Walker & Avant's concept analysis model. RESULTS: The attributes of oral frailty were abnormal oral structure and/or decline in multi-faceted oral function and coexisting decline in physical, cognitive and social functions. Its antecedents were aging, social frailty, and severe periodontitis, whereas its consequences were decline in physical health and mental health, social withdrawal, lower quality of life and systemic frailty. CONCLUSION: Oral frailty could result in worse conditions among older adults physically, psychologically and socially. Tools based on the concept analysis need to be developed to comprehensively assess oral frailty.

Analysis of hindering and facilitating factors of help-seeking behavior in schizophrenia based on COM-B model: a descriptive qualitative study.

BACKGROUND: Timely and systematic professional treatment is crucial in schizophrenia prognosis, but the global rate of mental health service, now, use or help-seeking behavior is low. METHODS: In-depth semi-structured interviews were conducted with 13 participants with the diagnosis of schizophrenia between October to December 2021. The participants were purposively sampled from a psychiatric hospital's. Interviews were recorded and transcribed verbatim into NVivo 12.0. RESULTS: The findings were summarized under 3 themes and 12 subthemes: (1) capability (lack of knowledge due to insufficient mental health literacy or lack of insight, inability to access disease information due to a lack of mental health literacy, and symptoms-related barriers); (2) opportunity (lack of disease information sources, inability to balance work and study during prolonged hospitalization, accessibility and convenience of medical resources, and the acquisition and utilization of social support); and (3) motivation (awareness of the disease and professional treatment, negative experiences of disease episodes, past medical experience, confidence in tcuring the disease, and the fulfillment of daily life and self-worth). CONCLUSION: The medical help-seeking behavior of people with the diagnosis of schizophrenia is the result of the interaction of many barriers and facilitators, and challenges persist today. Interventions can be implemented with the BCW framework and our results to precisely eliminate delays in the diagnosis and treatment of mental problems.

Construction and verification of aggressive behavior risk prediction model in stable patients with schizophrenia.

BACKGROUND: Among all types of mental disorders, individuals with schizophrenia exhibit the highest frequency of aggressive behavior. This disrupts the healthcare environment and poses threats to family life and social harmony. Present approaches fail to identify individuals with schizophrenia who are predisposed to aggressive behavior. In this study, we aimed to construct a risk prediction model for aggressive behavior in stable patients with schizophrenia, which may facilitate early identification of patients who are predisposed to aggression by assessing relevant factors, enabling the management of high-risk groups to mitigate and prevent aggressive behavior. METHODS: A convenience sample of stable inpatients with schizophrenia were selected from Daqing Municipal Third Hospital and Chifeng Municipal Anding Hospital from March 2021 to July 2023. A total of 429 patients with stable schizophrenia who met the inclusion criteria were included. A survey was conducted with them using a questionnaire consisting of general information questionnaire, Positive and Negative Symptom Scale, Childhood Trauma Questionnaire-Short Form, Connor-Davidson Resilience Scale and Self-esteem Scale. Patients enrolled in this study were divided into aggressive and non-aggressive groups based on whether there was at least one obvious and recorded personal attack episode (including obvious wounding and self-injurious behavior) following diagnosis. Binary Logistic regression was used to determine the influencing factors, and R software was used to establish a nomogram model for predicting the risk of aggressive behavior. Bootstrap method was used for internal validation of the model, and the validation group was used for external validation. C statistic and calibration curve were used to evaluate the prediction performance of the model. RESULTS: The model variables included Age, Duration of disease, Positive symptom, Childhood Trauma, Self-esteem and Resilience. The AUROC of the model was 0.790 (95% CI:0.729-0.851), the best cutoff value was 0.308; the sensitivity was 70.0%; the specificity was 81.4%; The C statistics of internal and external validation were 0.759 (95%CI:0.725-0.814) and 0.819 (95%CI:0.733-0.904), respectively; calibration curve and Brier score showed good fit. CONCLUSIONS: The prediction model has a good degree of discrimination and calibration, which can intuitively and easily screen the high risk of aggressive behavior in stable patients with schizophrenia, and provide references for early screening and intervention.

Sexual needs of people with schizophrenia: a descriptive phenomenological study.

BACKGROUND: Sexual health is one of the main areas of health and basic human rights which has been paid less attention in schizophrenia. Most studies have focused on sexual dysfunction rather than the sexual needs of people with schizophrenia. This study explores the sexual needs of people with schizophrenia and identify factors hindering sexual activities. METHODS: We carried out a qualitative study using a descriptive phenomenological approach. Data were collected at a psychiatric hospital in China. In total, 20 patients with schizophrenia were recruited through purposive sampling. Face to face semi-structured in-depth interviews were conducted with them. Interview recordings were transcribed by the research team, and transcripts were analyzed by two independent coders with Colaizzi's descriptive analysis framework by using NVivo 11 software. The consolidated criteria for reporting qualitative research checklist was used for reporting. RESULTS: The data analysis revealed 10 subthemes categorized into 3 macro themes: (1) multiple barriers hinder sexual activity; (2) significance of sex; and (3) conditions for fulfilling sexual needs. CONCLUSION: A poor sexual quality of life may be found in patients with schizophrenia. Furthermore, people with schizophrenia did not lose interest in maintaining an active sex life. Mental health services should address this issue in three areas: sexual knowledge, sexual space, and sexual objects.

Perception of risk of relapse among patients with first episode and recurrent schizophrenia: a descriptive phenomenological study.

BACKGROUND: Patients suffering from schizophrenia are at a higher risk of relapse. The perception of the risk of relapse in patients is critical for relapse prevention. In the field of psychiatry, the study of risk perception of relapse has been neglected. METHODS: We carried out a qualitative study using a descriptive phenomenological approach. Data were collected at two psychiatric hospitals in China. In total, 22 patients with schizophrenia were recruited through purposive sampling. Face to face semi-structured in-depth interviews were conducted. Interview recordings were transcribed by the research team, and transcripts were analysed by two independent coders with Colaizzi's descriptive analysis framework. The consolidated criteria for reporting qualitative research checklist were used for reporting. RESULTS: The data of first-episode patients yielded three themes: (i) lack of knowledge about disease recognition and medical treatment; (ii) overoptimistic estimation of the risk of relapse; (iii) perceived importance of treatment. For first-relapse patients : (i) initial awareness of relapse warning signs; (ii) lack of systematic and accurate assessment of disease information; (iii) the perception that drug withdrawal is related to relapse. Patients with multiple relapses: (i) susceptibility to relapse: confusion and powerlessness; (ii) the severity of relapse: suicidal thoughts and behavior; (iii) effects of perceived benefits and barriers of medication behaviour. CONCLUSIONS: In schizophrenic patients with first-episode, first-relapse, and multiple relapses, there were dynamic changes in the perception of disease relapse risk and medication behaviour. Medical workers must improve risk awareness education. They should provide patients with scientific, accurate, and timely communication channels, and dynamically assess and manage the risk of relapse in various patients.

Construction of a system for head and neck tumor traceless resection with non-inflatable transaxillary total endoscopic surgery.

Radical cure and functional preservation of tumors are the fundamental goals of surgical treatment of head and neck tumors, and the preservation of good aesthetics is a higher pursuit on this basis. Fully hiding the surgical incision and reducing the visibility of scars are important goals of cosmetic surgery. Using complete endoscopy for the head and neck is an effective method. CO2-free transaxillary total endoscopic surgery is a method with many advantages, which has been widely used in the resection of thyroid tumors, but for other parts and types of tumors in the head and neck, this surgical method is rarely used. The research team expanded its application scope and applied it to submandibular gland tumor resection and other head and neck surgeries for the first time. Through this exploration, it improved traction devices such as retractors, strictly limited the surgical indications, analyzed and summarized the key points, steps and methods of surgery, and built a treatment system for head and neck tumor surgery under complete endoscopy using the non-inflatable transaxillary approach. In this article, we introduce the system and select typical cases to share.

Patterns of lymph node metastasis in level IIB and contralateral level VI for papillary thyroid carcinoma with pN1b and safety of low collar extended incision for neck dissection in level II.

OBJECTIVE: To explore relevant clinical factors of level IIB and contralateral level VI lymph node metastasis and evaluate the safety of low-collar extended incision (LCEI) for lymph node dissection in level II for papillary thyroid carcinoma (PTC) with pN1b. METHOD: A retrospective analysis was performed on 218 patients with PTC with pN1b who were treated surgically in the Head and Neck Surgery Center of Sichuan Cancer Hospital from September 2021 to May 2022. Data on age, sex, body mass index (BMI), tumor location, maximum tumor diameter, multifocality, Braf gene, T staging, surgical incision style, and lymph node metastasis in each cervical subregion were collected. The chi-square test was used for comparative analysis of relevant factors. All statistical analyses were completed by SPSS 24 software. RESULT: Each subgroup on sex, age, BMI, multifocality, tumor location, extrathyroidal extension, Braf gene, and lymphatic metastasis in level III, level IV, and level V had no significant difference in the positive rate of lymph node metastasis in level IIB (P > 0.05). In contrast, patients with bilateral lateral cervical lymphatic metastasis were more likely to have level IIB lymphatic metastasis than those with unilateral lateral cervical lymphatic metastasis, with a statistically significant difference (P = 0.000). In addition, lymph node metastasis in level IIA was significantly associated with lymph node metastasis in level IIB (P = 0.001). After multivariate analysis, lymph node metastasis in level IIA was independently associated with lymph node metastasis in level IIB (P = 0.010). The LCEI group had a similar lymphatic metastasis number and lymphatic metastasis rate in both level IIA and level IIB as the L-shaped incision group (P > 0.05). There were 86 patients with ipsilateral central lymphatic metastasis (78.2%). Patients with contralateral central lymphatic metastasis accounted for 56.4%. The contralateral central lymphatic metastasis rate was not correlated with age, BMI, multifocality, tumor invasion, or ipsilateral central lymphatic metastasis, and there was no significant difference (P > 0.05). The contralateral central lymphatic metastasis in males was slightly higher than that in females, and the difference was statistically significant (68.2% vs. 48.5%, P = 0.041). CONCLUSION: Lymphatic metastasis in level IIA was an independent predictor of lymphatic metastasis in level IIB. When bilateral lateral cervical lymphatic metastasis or lymph node metastasis of level IIA is found, lymph node dissection in level IIB is strongly recommended. When unilateral lateral cervical lymphatic metastasis and lymphatic metastasis in level IIA are negative, lymph node dissection in level IIB may be performed as appropriate on the premise of no damage to the accessory nerve. LCEI is safe and effective for lymph node dissection in level II. When the tumor is located in the unilateral lobe, attention should be given to contralateral central lymph node dissection because of the high lymphatic metastasis rate.

The relationship between depression and subjective cognitive decline in older adults of China: the mediating role of general self-efficacy.

Subjective cognitive decline (SCD) is common in older adults and may also be an early marker for future cognitive impairment. Depression is an important influencing factor for subjective cognitive decline in old age. However, the mediating effects of general self-efficacy in depression and subjective cognition are yet to be explored. This study included 308 participants who were ≥60 years. Participants were asked to complete the self-report measures of the Geriatric Depression Scale-15 (GDS-15), Subjective Cognitive Decline-Questionnaire (SCD-Q), and General Self-Efficacy Scale (GSES). We used correlations, regressions, and structural equation models for the analyses. The bootstrapping method was performed to confirm the mediation effect. The subjective cognitive decline was found to be significantly and positively correlated to depression. Bootstrapping mediation analyses indicated that depression could affect SCD not only directly but also indirectly through general self-efficacy. General self-efficacy partly played a mediating role between depression and SCD. Hence, community workers and clinicians should actively help the elderly experiencing low levels of general self-efficacy to reduce their SCD.

The relationship between self-esteem and mental disability in patients with schizophrenia: the mediating role of resilience and the moderating role of gender.

This study aims to verify the mediating role of resilience between self-esteem and mental disability and to analyze the moderating role of gender in the relationship between resilience and mental disability in patients with schizophrenia. Patients with schizophrenia have been selected from Harbin Psychiatric (Baiyupao) Hospital and Daqing Third Hospital in Heilongjiang Province from January to December 2021. The study recruited a total of 220 patients with schizophrenia, including 120 males and 100 females to measure their self-esteem, resilience and mental disability. The results were as follows: Self-esteem and resilience are important protective factors that have a buffering effect on mental disability. The mediating effect of resilience on self-esteem and mental disability is stronger in males than in females. The results provide new ideas for delaying mental disability and for formulating intervention programs and applying them to clinical practice. The study indicates that psychiatric medical staff should not only treat the patients with schizophrenia psychotic symptoms but also improve their self-esteem and resilience through effective intervention to reduce the occurrence of mental disability.

MALDI-TOF-MS for Rapid Screening and Typing of ß-Globin Variant and ß-Thalassemia through Direct Measurements of Intact Globin Chains.

BACKGROUND: Traditional phenotype-based screening for ß-globin variant and ß-thalassemia using hematological parameters is time-consuming with low-resolution detection. Development of a MALDI-TOF-MS assay using alternative markers is needed. METHODS: We constructed a MALDI-TOF-MS-based approach for identifying various ß-globin disorders and classifying thalassemia major (TM) and thalassemia intermedia (TI) patients using 901 training samples with known HBB/HBA genotypes. We then validated the accuracy of population screening and clinical classification in 2 separate cohorts consisting of 16 172 participants and 201 ß-thalassemia patients. Traditional methods were used as controls. Genetic tests were considered the gold standard for testing positive specimens. RESULTS: We established a prediction model for identifying different forms of ß-globin disorders in a single MALDI-TOF-MS test based on δ- to ß-globin, γ- to α-globin, γ- to ß-globin ratios, and/or the abnormal globin-chain patterns. Our validation study yielded comparable results of clinical specificity (99.89% vs 99.71%), and accuracy (99.78% vs 99.16%) between the new assay and traditional methods but higher clinical sensitivity for the new method (97.52% vs 88.01%). The new assay identified 22 additional abnormal hemoglobins in 69 individuals including 9 novel ones, and accurately screened for 9 carriers of deletional hereditary persistence of fetal hemoglobin or δß-thalassemia. TM and TI were well classified in 178 samples out of 201 ß-thalassemia patients. CONCLUSIONS: MALDI-TOF-MS is a highly accurate, predictive tool that could be suitable for large-scale screening and clinical classification of ß-globin disorders.

circ_0000045 promotes proliferation, migration, and invasion of head and neck squamous cell carcinomas via regulating HSP70 and MAPK pathway.

OBJECTIVE: Head and neck squamous cell carcinoma (HNSCC) is one severe malignancy driven by complex cellular and signaling mechanisms. However, the roles of circular RNAs (circRNAs) in HNSCC's development remains poorly understood. Therefore, this study investigated the functions of differentially expressed circRNAs in regulating HNSCC cell functions. METHODS: Differentially expressed circRNAs were characterized through RNA sequencing in HNSCC tissues. CircRNA's identity was then confirmed using RT-PCR and Sanger's sequencing. Next, expression levels of circRNA and mRNA were detected by qRT-PCR, after which protein abundances were measured by Western blotting. Subsequently, the proliferation, migration, and invasion of HNSCC cells was assessed by MTS, wound healing, and Transwell system, respectively, followed by identification of circRNA-binding proteins in HNSCC cells by circRNA pull-down, coupled with mass spectrometry. RESULTS: Great alterations in circRNA profiles were detected in HNSCC tissues, including the elevated expression of circ_0000045. As observed, silencing of circ_0000045 effectively repressed the proliferation, migration, and invasion of HNSCC cell lines (FaDu and SCC-9). Contrarily, circ_0000045's overexpression promoted the proliferation, migration, and invasion in FaDu and SCC-9 cells. Results also showed that circ_0000045 was associated with multiple RNA-binding proteins in HNSCC cells, such as HSP70. Moreover, circ_0000045 knockdown enhanced HSP70 expression and inhibited JNK2 and P38's expression in HNSCC cells, which were oppositely regulated by circ_0000045's overexpression. CONCLUSION: The high expression of circ_0000045; therefore, promoted cell proliferation, migration, and invasion during HNSCC's development through regulating HSP70 protein and mitogen-activated protein kinase signaling.

Digital surgery group versus traditional experience group in head and neck reconstruction: a retrospective controlled study to analyze clinical value and time-economic-social effect.

OBJECTIVE: Discuss the application value of digital surgical technology in the reconstruction of head and neck defects after tumor resection and comprehensively evaluate time-economic-benefit cost. METHODS: A retrospective analysis of head and neck cancer patients who underwent reconstructive operations in head and neck surgery at Sichuan Cancer Hospital from January 2015 to January 2021 was performed. According to the inclusion and exclusion criteria, a total of 52 cases were included, including 25 cases using digital surgery (DS) and 27 cases using the conventional surgery (CS). The clinical-pathological characteristics, postoperative complications, functional aesthetic evaluation indexes, and time-cost-satisfaction evaluation indexes between the two groups were compared and statistically analyzed. Typical cases using digital surgery were shared. RESULTS: Outcomes between the two groups were comparable, and there was no significant difference in survival outcome and follow-up time between the two groups (P > 0.05). There was no significant difference between the two groups in the defect size, pathological type, other major clinicopathological features, or operation-related indicators (P > 0.05). The incidence of titanium plate displacement, deformation or exposure, and facial scar deformity in the DS group was significantly lower than that in the CS group (P < 0.05). However, there was no significant difference in other short-term or long-term complications (P > 0.05). The incidence of dysphagia and eating disorders in the DS group was significantly reduced (P < 0.05). The speech and social functions were improved, but not significantly (P > 0.05). Meanwhile, there was no significant difference in the evaluation index of facial aesthetics in this study (P > 0.05). Furthermore, the total operation time, preparation time of bone flap from the donor site, osteotomy time, and reconstruction time in the DS group were significantly lower than those in the traditional operation group (P < 0.05), but the shaping time and vascular anastomosis time of recipient area could not be shortened (P > 0.05). In addition, there was no significant difference in total hospitalization days between the DS group and CS group (P > 0.05), but the time of ICU treatment and postoperative intravenous nutrition support in the DS group were shorter than those in the CS group (P < 0.05). In particular, the preoperative doctor-patient communication of the DS group was more effective, and the treatment satisfaction of patients including their families was higher after operation (P < 0.05). CONCLUSION: Comprehensive application of digital surgical technology (CAD, CAM, VR, MA, etc.) in the reconstruction of the head and neck after tumor resection is feasible in clinical practice, which can not only improve the accuracy of repair, decrease some surgical complications, better preserve and improve patient's diet and speech function, and reduce the operation and hospitalization time, but also increase the treatment cost. Furthermore, it is conducive to doctor-patient communication and improves patient satisfaction.

Efficacy of group reminiscence therapy based on Chinese traditional festival activities (CTFA-GRT) on loneliness and perceived stress of rural older adults living alone in China: a randomized controlled trial.

OBJECTIVES: This study aimed to explore the efficacy of group reminiscence therapy based on Chinese traditional festival activities (CTFA-GRT) to mediate the loneliness and perceived stress of older adults living alone in rural China. The results can provide a scientific foundation for improving psychological health. METHOD: A randomized controlled trial of 64 (aged 65.70 ± 3.69 years) Chinese rural older adults living alone was conducted. They were randomly divided into either an eight-month intervention group or a control group. The perceived stress scale (PSS) and the UCLA loneliness scale (UCLA-LS) evaluated the perceived stress and loneliness of the two groups at three different times. A repeated-measures analysis of variance model was used to compare each outcome measure of the two groups. RESULTS: The CTFA-GRT yielded a benefit for the perceived stress and loneliness of rural older adults living alone in the intervention group. Combined with a simple effects test, the PSS and UCLA-LS of those in the intervention groups significantly decreased at eight months after the baseline (F PSS = 23.540, F UCLA-LS = 40.159; all P < 0.01). In addition, the sustainable effect of this program lasted three months after the intervention (F PSS = 65.756, F UCLA-LS = 60.983; all P < 0.01). CONCLUSION: The CTFA-GRT significantly decreased the perceived stress and loneliness of rural older adults living alone in China.

Social support, self-worth, and subjective well-being in older adults of rural China: a cross-sectional study.

This study explored the relationship between social support and subjective well-being of the rural Chinese older adults and investigated whether self-worth could mediate this association. A total number of 356 older adults from rural areas of China were investigated using three scales. The results were as follows: there were significant correlations between social support, self-worth, and subjective well-being (where P < 0.01 in all of them). Bootstrapping mediation analyses indicated that self-worth partly mediated the association between social support and subjective well-being. Accordingly, social support and self-worth are important targets for improving the subjective well-being level of the rural older adults.

Cumulative effect of risk and protective factors on unintentional injury for Chinese rural children: a nested case-control study.

BACKGROUND: Childhood unintentional injuries are the leading cause of death and disability for children. Despite the risk factors that lead to the occurrence of injuries have been identified, the relationship between cumulative effect of risk/protective factors and unintentional injuries is unclear. The aim of this study was to explore the cumulative effect of risk factors as well as protective factors and their interaction on unintentional injury to rural children. METHODS: We used a nested case-control study design from a cohort database. The study comprised 1696 children aged 6 to 14 years. Among them, 424 were cases with unintentional injury and 1272 were their matched control. After controlling for the significant sociodemographic variables, linear and logistic regression analyses were performed. RESULTS: The risk of unintentional injury increased with the increasing number of risk factors - RFI from 1 to 3 (ORRFI(1) = 0.978, 95% CI 0.739-1.296), (ORRFI(2) = 1.720, 95% CI 1.233-2.397), (ORRFI(3) = 5.162, 95% CI 3.129-8.517). PFI (1) was associated with lower risk of injury, but this association was at the edge of significance (p = 0.052). The increased risk in those with PFI (2) was not significant (p = 0.254). The severity of the unintentional injury significantly increased with the increasing number of the risk factors (p < 0.01), and significantly decreased with both the increasing number of protective factors (p = 0.001) and interaction of the risk and protective factors (p < 0.01).The interaction of RFI and PFI could explain 32.2% of the unintentional injury severity. CONCLUSIONS: According to the findings of the present study, cumulative risk factors and protective factors, as well as their interaction were associated with the occurrence and/ or severity of unintentional injury in children.

Epidemiological and clinical characteristics of respiratory viruses in 4403 pediatric patients from multiple hospitals in Guangdong, China.

BACKGROUND: Acute respiratory infections (ARI) cause considerable morbidity and mortality worldwide, especially in children. Unfortunately, there are limited multi-center data on common viral respiratory infections in south China. METHODS: A total of 4403 nasal swabs were collected from children in 10 cities in Guangdong, China in 2019. Seven respiratory viruses, influenza A virus (IFA), influenza B virus (IFB), respiratory syncytial virus (RSV), adenoviruses (ADV) and parainfluenza virus types 1-3 (PIV1, PIV2 and PIV3), were detected by direct immunofluorescence antibody assay. The personal information and clinical characteristics were recorded and analyzed. RESULTS: The results showed that at least one virus was detected in 1099 (24.96 %) samples. The detection rates of RSV, IFA, ADV, PIV3, PIV1 and PIV2 were 7.13 % (314/4403), 5.31 % (234/4403), 4.02 % (177/4403), 3.04 % (134/4403), 1.70 % (75/4403) and 1.16 % (51/4403), respectively. The detection rate of RSV was highest in 0-6-month-old children at 18.18 % (106/583), while the detection rate of IFA was highest in 12-18-year-old children at 20.48 % (17/83). The total detection rates in winter and spring were 35.67 % (219/614) and 34.56 % (403/1166), higher than those in summer, 17.41 % (284/1631), and autumn, 19.46 % (193/992). CONCLUSIONS: RSV and IFA were the main respiratory viruses in children. With increasing age the detection rate of RSV decreased in children, but the trends for the detection rates of IFA and IFB were the opposite. This study provided the viral etiology and epidemiology of pediatric patients with ARI in Guangdong, China.
