Social anxiety mediates between victimization experiences and internet addiction among adolescents: results from propensity score matching.

Background: Previous research has indicated that Victimization Experiences (VE) may be linked to a heightened likelihood of developing psychological symptoms and Internet Addiction (IA) among adolescents. However, the precise mechanism through which VE contributes to IA in adolescents remains uncertain. This study aimed to investigate whether Social Anxiety (SA) serves as a mediation between VE and IA, utilizing the framework of General Strain Theory. Methods: A cross-sectional survey among 11 middle schools or high schools in Macao was conducted from October to December 2022. Respondents in the victimized group and non-victimized group were 1:1 paired using Propensity Score Matching (PSM) to control the potential confounding factors. Results: A total of 1,089 questionnaires were valid for analysis and 311 pairs were generated through PSM. Respondents in the victimized group reported significantly higher IA than those in non-victimized group (23.5% vs. 12.5%, p < 0.001) after PSM treatment. Multivariate logistic regression analysis showed that VE (p = 0.015, OR = 1.750, 95% CI = 1.115 to 2.746, E-value = 2.90) and SA (p < 0.001, OR = 1.052, 95% CI = 1.030 to 1.074, E-value = 1.29) were the predictors of IA. The model successfully classified 81.7% of cases overall (R 2 N = 0.133). Further analysis indicated that SA mediates between VE and IA (Z = 3.644, p < 0.001). Conclusion: This study revealed the potential mediation effect of SA on the link between VE and IA. By acknowledging the mediating influence of SA, researchers and practitioners can develop more accurate and effective strategies to mitigate Internet Addiction among adolescents.

Perspectives on dementia care self-learning platform: A focus group study of family and professional caregivers.

OBJECTIVE: To compare perspectives of family and professional caregivers regarding an online self-learning platform. METHODS: Family and professional caregivers were interviewed separately. A thematic analysis was conducted with 12 family caregivers and 13 professional caregivers of people living with dementia in Macao using six semi-structured focus group interviews. RESULTS: Family and professional caregivers had different perspectives regarding the application of online learning program Four main themes emerged from the focus groups, including similarities and differences, namely 1) Need for services; 2) Accessibility to services; 3) Barriers to online learning; 4) Adjustments to the platform. CONCLUSIONS: The psychological assurance offered by an online learning program is imperative to the well-being of family caregivers. By identifying the gap between the needs and abilities of family caregivers and those imagined by professional caregivers, it allows for the development of support programs and interventions tailored to meet the specific needs of family caregivers.

The Radiological Characteristics of Degenerative Cervical Kyphosis with Cervical Spondylotic Myelopathy.

Introduction: In this study, we aim to describe the radiological characteristics of degenerative cervical kyphosis (DCK) with cervical spondylotic myelopathy (CSM) and discuss the relationship between DCK and the pathogenesis of spinal cord dysfunction. Methods: In total, 90 patients with CSM hospitalized in our center from September 2017 to August 2022 were retrospectively examined in this study; they were then divided into the kyphosis group and the nonkyphosis group. The patients' demographics, clinical features, and radiological data were obtained, including gender, age, duration of illness, cervical Japanese Orthopaedic Association (JOA) score, cervical lordosis (CL), height of intervertebral space, degree of wedging vertebral body, degree of osteophyte formation, degree of disc herniation, degree of spinal cord compression, and anteroposterior diameter of the spinal cord. In the kyphosis group, kyphotic segments, apex of kyphosis, and segmental kyphosis angle were recorded. Radiological characteristics between the two groups were also compared. Correlation analysis was performed for different spinal cord compression types. Results: As per our findings, the patients in the kyphosis group showed more remarkable wedging of the vertebral body, more severe anterior compression of the spinal cord, and a higher degree of disc herniation, while the posterior compression of the spinal cord was relatively mild when compared with the nonkyphosis group. CL was related to the type of spinal cord compression, as cervical kyphosis is an independent risk factor for anterior spinal cord compression. Conclusions: DCK might play a vital role in the pathogenesis of spinal cord dysfunction. In patients with DCK, it was determined that the anterior column is less supported, and more severe anterior spinal cord compression is present. The anterior approach is supposed to be preferred for CSM patients with DCK.

Evidence from mendelian randomization identifies several causal relationships between primary membranous nephropathy and gut microbiota.

BACKGROUND: Research has showcased a correlation between disruptions in gut microbiota and primary membranous nephropathy (pMN), giving rise to the concept of the 'gut-kidney axis'. However, the precise relationship between gut microbiota and pMN remains elusive. Hence, this study endeavors to investigate whether a causal relationship exists between gut microbiota and pMN utilizing Mendelian randomization (MR) analysis. METHODS: The primary method employed for MR analysis is the inverse variance weighting method, supplemented by MR-Egger and the weighted median method, to infer causality. This approach was validated within the pMN cohort across two distinct populations. RESULTS: At the species level, the abundance of Bifidobacterium bifidum and Alistipes indistinctus was negatively correlated with the risk of pMN. Conversely, pMN was positively associated with Bacilli abundance at the class level, Lachnospiraceae abundance at the family level, and Dialister abundance at the genus level. Specifically, at the species level, pMN was positively correlated with the abundance of Ruminococcus lactaris, Dialister invisus, and Coprococcus_sp_ART55_1. CONCLUSION: These findings lay the groundwork for future research exploring the interplay between pMN and the gut microbiota, with substantial implications for the prevention and treatment of pMN and its associated complications.

Labeling and Diagnostic Value of miRNA-28-3p in Patients with Nasopharyngeal Carcinoma.

Objective: To explore how miRNA-28-3p targets BIN1 and affects the biological behavior of nasopharyngeal carcinoma cells, and to evaluate its potential as a predictive biomarker for NPC. Methods: We studied 100 nasopharyngeal carcinoma patients who underwent surgery between January 2021 and January 2022. Tissues from tumors and adjacent normal areas were analyzed. Participants were categorized into two groups: one with nasopharyngeal carcinoma and another with adjacent normal tissue. Additionally, the nasopharyngeal carcinoma cell line CNE-2 was divided into three groups: an untreated control, a negative control with NC plasmid, and a test group treated with a miRNA-28-3p inhibitor. Key techniques included PCR, Western blotting, CCK-8, flow cytometry, focusing on the interactions between miRNA-28-3p and BIN1 and their predictive significance for NPC. Results: miRNA-28-3p levels were significantly higher in nasopharyngeal carcinoma tissues compared to adjacent normal tissues (P < .05). The predictive performance of miRNA-28-3p for NPC featured an AUC > 0.75 with sensitivity and specificity both exceeding 70% (P < .001). In nasopharyngeal carcinoma cells, miRNA-28-3p levels were significantly elevated compared to normal cells (P < .05). Transfection with the miRNA-28-3p inhibitor increased apoptosis and BIN1 protein levels while reducing cell proliferation, invasion, and migration significantly (P < .05). Conclusion: miRNA-28-3p is overexpressed in nasopharyngeal carcinoma and inhibits tumor cell proliferation, migration, and invasion, while promoting apoptosis by targeting BIN1. The level of miRNA-28-3p expression serves as a sensitive indicator for predicting nasopharyngeal carcinoma, affirming its potential as a diagnostic biomarker and underscoring the significance of these findings in enhancing understanding and clinical management of NPC.

The paulownia bagworm, Clania variegata Snell, is an economically important pest of agriculture and forests. The sex pheromone of this pest and its stereoisomers were synthesized, and two of the stereoisomers were prepared for the first time. Our strategy was efficient and mainly included the ring-opening reaction of (S)-2-methyloxirane, the coupling of chiral sulfonate, the oxidative cleavage of olefin, and Yamaguchi esterification. Moreover, the overall yields of our synthesis were 23-29%, with eight steps in the longest route.

Development of aptamer surface-enhanced Raman spectroscopy sensor based on Fe3O4@Pt and Au@Ag nanoparticles for the determination of acetamiprid.

As a common chlorinated nicotinic pesticide with high insecticidal activity, acetamiprid has been widely used for pest control. However, the irrational use of acetamiprid will pollute the environment and thus affect human health. Therefore, it is crucial to develop a simple, highly sensitive, and rapid method for acetamiprid residue detection. In this study, the capture probe (Fe3O4@Pt-Aptamer) was connected with the signal probe (Au@DTNB@Ag CS-cDNA) to form an assembly with multiple SERS-enhanced effects. Combined with magnetic separation technology, a SERS sensor with high sensitivity and stability was constructed to detect acetamiprid residue. Based on the optimal conditions, the SERS intensity measured at 1333 cm-1 is in relation to the concentration of acetamiprid in the range 2.25 × 10-9-2.25 × 10-5 M, and the calculated limit of detection (LOD) was 2.87 × 10-10 M. There was no cross-reactivity with thiacloprid, clothianidin, nitenpyram, imidacloprid, and chlorpyrifos, indicating that this method has good sensitivity and specificity. Finally, the method was applied to the detection of acetamiprid in cucumber samples, and the average recoveries were 94.19-103.58%, with RSD < 2.32%. The sensor can be used to analyse real samples with fast detection speed, high sensitivity, and high selectivity.

Effects of grazing exclusion on soil microbial diversity and its functionality in grasslands: a meta-analysis.

Grazing exclusion (GE) is considered an effective strategy for restoring the degradation of overgrazed grasslands on the global scale. Soil microbial diversity plays a crucial role in supporting multiple ecosystem functions (multifunctionality) in grassland ecosystems. However, the impact of grazing exclusion on soil microbial diversity remains uncertain. Here, we conducted a meta-analysis using a dataset comprising 246 paired observations from 46 peer-reviewed papers to estimate how GE affects microbial diversity and how these effects vary with climatic regions, grassland types, and GE duration ranging from 1 to 64 years. Meanwhile, we explored the relationship between microbial diversity and its functionality under grazing exclusion. Overall, grazing exclusion significantly increased microbial Shannon (1.9%) and microbial richness (4.9%) compared to grazing group. For microbial groups, GE significantly increased fungal richness (8.6%) and bacterial richness (5.3%), but decreased specific microbial richness (-11.9%). The responses of microbial Shannon to GE varied among climatic regions, grassland types, and GE duration. Specifically, GE increased microbial diversity in in arid, semi-arid, and dry sub-humid regions, but decreased it in humid regions. Moreover, GE significantly increased microbial Shannon in semidesert grasslands (5.9%) and alpine grasslands (3.0%), but not in temperate grasslands. Long-term (>20 year) GE had greater effects on microbial diversity (8.0% for Shannon and 6.7% for richness) compared to short-term (<10 year) GE (-0.8% and 2.4%). Furthermore, grazing exclusion significantly increased multifunctionality, and both microbial and plant Shannon positively correlated with multifunctionality. Overall, our findings emphasize the importance of considering climate, GE duration, and grassland type for biodiversity conservation and sustainable grassland ecosystem functions.

Design, synthesis, and biological evaluation of aralkyl piperazine and piperidine derivatives targeting SSRI/5-HT1A/5-HT7.

Serotonin reuptake inhibition combined with the action targeting 5-hydroxytryptamine receptor subtypes can serve as a potential target for the development of antidepressant drugs. Herein a series of new aralkyl piperazines and piperidines were designed and synthesized by the structural modifications of the previously discovered aralkyl piperidine compound 1, targeting SSRI/5-HT1A/5-HT7. The results exhibited that compound 5a showed strong binding to 5-HT1A and 5-HT7 (Ki of 0.46 nM, 2.7 nM, respectively) and a high level of serotonin reuptake inhibition (IC50 of 1.9 nM), all of which were significantly elevated compared to 1. In particular, compound 5a showed weaker inhibitory activity against hERG than 1, and demonstrated good stability in liver microsomes in vitro. The preliminary screening using FST indicated that orally administered 5a, at a high dose, could reduce immobility time in mice markedly, indicating potential antidepressant activity.

Association between the sarcopenia-related traits and Parkinson's disease: A bidirectional two-sample Mendelian randomization study.

OBJECTIVE: To explore the causal association between sarcopenia-related traits and Parkinson's disease by Mendelian randomization (MR) approach. METHODS: A genome-wide association study (GWAS) of sarcopenia-related traits was done at the UK Biobank (UKB). The traits were appendicular lean mass, low hand grip strength (including the European Working Group on Sarcopenia in Older People (EWGSOP) and the Foundation for the National Institutes of Health (FNIH) criteria and usual walking pace. The International Parkinson's Disease Genomics Consortium (IPDGC) gave us GWAS data for Parkinson's disease (PD). We used three different types of MR analyses: including Inverse-variance weighted (IVW), Mendelian randomized Egger regression (MR-Egger), and weighted median methods (both weighted and simple modes). RESULTS: The MR analysis showed that low hand grip strength was negatively associated with the risk of developing Parkinson's disease, including EWGSOP criterion (odds ratio (OR) = 0.734; 95% confidence interval (CI) = 0.575-0.937, P = 0.013) and FNIH criterion (OR = 0.619; 95% CI = 0.419-0.914, P = 0.016), and usual walking pace was also a risk factor for Parkinson's disease (OR = 3.307, 95% CI = 1.277-8.565, P = 0.014). CONCLUSIONS: In European population, low hand grip strength is negatively associated with the risk of developing Parkinson's disease, and usual walking pace is also a risk factor for Parkinson's disease. Further exploration of the potential genetic mechanisms underlying hand grip strength and Parkinson's disease and the potential relationship between walking pace, balance, and falls in Parkinson's patients may help to reduce the burden of sarcopenia and Parkinson's disease.

Autonomic dysfunction and treatment strategies in intracerebral hemorrhage.

AIMS: Autonomic dysfunction with central autonomic network (CAN) damage occurs frequently after intracerebral hemorrhage (ICH) and contributes to a series of adverse outcomes. This review aims to provide insight and convenience for future clinical practice and research on autonomic dysfunction in ICH patients. DISCUSSION: We summarize the autonomic dysfunction in ICH from the aspects of potential mechanisms, clinical significance, assessment, and treatment strategies. The CAN structures mainly include insular cortex, anterior cingulate cortex, amygdala, hypothalamus, nucleus of the solitary tract, ventrolateral medulla, dorsal motor nucleus of the vagus, nucleus ambiguus, parabrachial nucleus, and periaqueductal gray. Autonomic dysfunction after ICH is closely associated with neurological functional outcomes, cardiac complications, blood pressure fluctuation, immunosuppression and infection, thermoregulatory dysfunction, hyperglycemia, digestive dysfunction, and urogenital disturbances. Heart rate variability, baroreflex sensitivity, skin sympathetic nerve activity, sympathetic skin response, and plasma catecholamine concentration can be used to assess the autonomic functional activities after ICH. Risk stratification of patients according to autonomic functional activities, and development of intervention approaches based on the restoration of sympathetic-parasympathetic balance, would potentially improve clinical outcomes in ICH patients. CONCLUSION: The review systematically summarizes the evidence of autonomic dysfunction and its association with clinical outcomes in ICH patients, proposing that targeting autonomic dysfunction could be potentially investigated to improve the clinical outcomes.

Views of healthcare professionals on their relationships with families of people living with dementia: A qualitative study.

OBJECTIVE: Healthcare professionals as well as families play a vital role in ensuring the quality of care for people living with dementia. However, the relationships between healthcare professionals and families of people living with dementia are not extensively examined, particularly within the Chinese cultural context of dementia. The goal of this study was to explore the views of healthcare professionals on their relationships with families of people living with dementia. DESIGN: This qualitative study was grounded in the interpretative phenomenological analysis framework. METHODS: Data were collected using focus-group interviews. Qualitative data were transcribed verbatim and analysed using interpretative phenomenological analysis. RESULTS: The study recruited a total of 26 healthcare professionals from 3 long-term care facilities. The study found that conflicts were inherent in the relationships between professionals and families of people living with dementia, and conflicts were found to manifest in three core domains: 1) Families demonstrated a lack of understanding about dementia, 2) Professionals faced challenges in managing families' unrealistic expectations regarding the disease status and the prognosis of people living with dementia, 3) Families did not perceive themselves as being responsible for the care of people living with dementia. CONCLUSIONS: The present study found that the prevailing factor underpinning the relational conflicts between healthcare professionals and families of people living with dementia, as reported by healthcare professionals was the perceived lack of understanding about dementia amongst families of those affected.

Aspherical interferometric probe with wave-plate-array detection: system design and nonlinearity analysis.

Optical probes are the preferred choice for high-precision surface metrology, necessitating improved flexibility and a broader range of motion to adapt to the increasing complexity of surfaces. This study introduces an interferometric probe designed for measuring aspheric surfaces, utilizing a wave-plate-array detection component. By integrating splitter elements into the detector, the probe improves integration and dynamic scanning performance, while maintaining high-precision measurement capability. The system design and working principle are explored, and comprehensive nonlinear models based on the Jones matrix theory are established. These models focus on the nonlinear errors arising from alignment errors in various cases. Moreover, rigorous numerical simulations and optical experiments are conducted to validate the proposed models. When the alignment error reaches 10°, it results in a maximum nonlinear error of 3.02 nm. The experimental results demonstrate the effectiveness of the models in capturing nonlinear errors induced by alignment errors, providing a theoretical foundation for error reduction and compensation.

MiR-124-3p mediates gastric cancer cell ferroptosis induced by an anti-cancer drug polyphyllin I.

Background: Ferroptosis is an emerging type of regulated cell death and associated with antitumoral therapy, while some microRNAs have been shown to regulate the tumorigenesis and cancer progression. Meanwhile, polyphyllin I (PPI) has exhibited antitumoral effects by promoting cancer cell apoptosis and ferroptosis. However, it is unclear whether PPI induces cancer cell ferroptosis by regulating microRNAs. Methods: We used two gastric cancer cell lines (AGS and MKN-45) to set up a tumor model of the nude mice, which were then treated daily with PPI to measure the cancer growth in vitro and in vivo. Ferroptosis was measured using immunofluorescence staining and flow cytometric analysis according to levels of intracellular ROS, lipid ROS and ferrous ions. Moreover, NRF2 expression was measured by Western blotting. In some experiments, the mimics or inhibitors of miR-124-3p were used to further confirm its involvement in PPI-induced cancer cell ferroptosis. Results: Here we found that miR-124-3p mediated cancer ferroptosis and tumor repression induced by PPI since PPI increased miR-124-3p expression in gastric cancer cells and promoted their ferroptosis, whereas inhibition of miR-124-3p mostly abolished the effects of PPI on tumor growth, ferroptosis and NRF2 expression. Moreover, miR-124-3p mimics promoted cancer cell ferroptosis by downregulating NRF2 through directly targeting 3'-UTR region of NRF2, confirming a role for miR-124-3p in regulating PPI-induced ferroptosis. Conclusion: PPI exerts its antitumoral effects on the gastric cancer by promoting cell ferroptosis via regulating miR-124-3p. Our findings have clinical implications for cancer chemotherapy.

Lack of association between nonalcoholic fatty liver disease and intracerebral hemorrhage: A community-based cohort study.

BACKGROUND: The association between nonalcoholic fatty liver disease (NAFLD) and intracerebral hemorrhage (ICH) remains unclear. This study aimed to investigate whether NAFLD and its severity predict incident ICH. METHODS: Participants free of other liver diseases, prior stroke, myocardial infarction, cancer, or alcohol abuse in the Kailuan cohort were enrolled in this study. Abdominal ultrasonography was used to diagnose NAFLD and assess its severity. Participants were stratified into different groups including nonfatty liver, mild, moderate and severe NAFLD. Multivariable Cox proportional hazards regression models were used to evaluate the hazard ratios (HRs) and 95% CIs of ICH events in the 11-year follow-up. RESULTS: A total of 77,461 participants were enrolled in our study. Among them, NAFLD was diagnosed in 23,890 (30.83 %) participants, including 15,581 (20.11 %) with mild NAFLD, 6839 (8.83 %) with moderate NAFLD and 1470 (1.90 %) with severe NAFLD. We documented 692 ICH events during 848,579 person years of follow-up. Patients with more severe NAFLD tended to be older, had higher levels of BMI, higher proportions of hypertension, diabetes and other known risk factors for cerebrovascular disease. However, there was no significant associations between NAFLD, its severity and incident ICH events. Relative to nonfatty liver participants, the HRs for participants with mild NAFLD, moderate and severe NAFLD were 0.98 (95 % CI, 0.80 to 1.20), 1.19 (95 % CI, 0.92 to 1.54) and 1.29 (95 % CI, 0.81 to 2.06), respectively. CONCLUSIONS: NAFLD and its severity did not appear to be significantly associated with ICH after adjustment for potential risk factors.

Development and internal validation of a novel nomogram for predicting lymph node invasion for prostate cancer patients undergoing extended pelvic lymph node dissection.

Background: Few studies have focused on the performance of Briganti 2012, Briganti 2017 and MSKCC nomograms in the Chinese population in assessing the risk of lymph node invasion(LNI) in prostate cancer(PCa) patients and identifying patients suitable for extended pelvic lymph node dissection(ePLND). We aimed to develop and validate a novel nomogram based on Chinese PCa patients treated with radical prostatectomy(RP) and ePLND for predicting LNI. Methods: We retrospectively retrieved clinical data of 631 patients with localized PCa receiving RP and ePLND at a Chinese single tertiary referral center. All patients had detailed biopsy information from experienced uropathologist. Multivariate logistic-regression analyses were performed to identify independent factors associated with LNI. The discrimination accuracy and net-benefit of models were quantified using the area under curve(AUC) and Decision curve analysis(DCA).The nonparametric bootstrapping were used to internal validation. Results: A total of 194(30.7%) patients had LNI. The median number of removed lymph nodes was 13(range, 11-18). In univariable analysis, preoperative prostate-specific antigen(PSA), clinical stage, biopsy Gleason grade group, maximum percentage of single core involvement with highest-grade PCa, percentage of positive cores, percentage of positive cores with highest-grade PCa and percentage of cores with clinically significant cancer on systematic biopsy differed significantly. The multivariable model that included preoperative PSA, clinical stage, biopsy Gleason grade group, maximum percentage of single core involvement with highest-grade PCa and percentage of cores with clinically significant cancer on systematic biopsy represented the basis for the novel nomogram. Based on a 12% cutoff, our results showed that 189(30%) patients could have avoided ePLND while only 9(4.8%) had LNI missing ePLND. Our proposed model achieved the highest AUC (proposed model vs Briganti 2012 vs Briganti 2017 vs MSKCC model: 0.83 vs 0.8 vs 0.8 vs 0.8, respectively) and highest net-benefit via DCA in the Chinese cohort compared with previous nomograms. In internal validation of proposed nomogram, all variables had a percent inclusion greater than 50%. Conclusion: We developed and validated a nomogram predicting the risk of LNI based on Chinese PCa patients, which demonstrated superior performance compared with previous nomograms.

Non-destructive and in-situ detection of shrimp freshness using mid-infrared fiber-optic evanescent wave spectroscopy.

There is strong interest in non-destructive and rapid determination of food freshness in food research. In this study, mid-infrared (MIR) fiber-optic evanescent wave (FOEW) spectroscopy was applied to monitor shrimp freshness through the evaluation of protein, chitin, and calcite contents in conjunction with a Partial Least Squares Discriminant Analysis (PLS-DA) model. Shrimp shells were wiped with a micro fiber-optic probe to obtain a FOEW spectrum which quickly and nondestructively allowed evaluation of the shrimp freshness. Peaks for proteins, chitin, and calcite, which are closely related to shrimp freshness, were detected and quantified. Compared with the standard indicator for evaluating shrimp freshness (total volatile basic nitrogen), the PLS-DA model gave recognition rates for shrimp freshness using calibration and validation sets of the FOEW data of 87.27%, 90.28%, respectively. Our results show that FOEW spectroscopy is a feasible method for non-destructive and in-site detection of shrimp freshness.

Molecular and Cellular Mechanisms of Neuropathic Pain in Aging.

Neuropathic pain is a chronic condition that tends to worsen over time, leading to a significant decline in patients' quality of life. The elderly population is disproportionately affected by this burden, as evidenced by the high prevalence of this condition in such a demographic. While previous studies have demonstrated the involvement of various signaling pathways critical to neuropathic pain, the relationship between aging and the onset or persistence of this condition has been overlooked. Greater focus was placed on the efficacy and tolerability of medications, as well as new protocols for assessing pain in patients with cognitive impairment, with less regard for reasons underlying the increased susceptibility of elderly individuals to pain. This Review thus aims to summarize the contributions of aging to neuropathic pain, covering weakened repair function, increased intracellular calcium signaling, enhanced oxidative stress, dysfunctional brain function, impaired descending inhibition, alterations in the innate immune cell population, and the effects of comorbidity caused by aging. A better understanding of these aspects could drive new treatment options thereby yielding better outcomes for elderly patients in pain.
