Methodology: These were retrospective descriptive studies of patient consultation and hospitalization records in the 17 psychiatric and addictology care centers in Senegal from 2018 to 2022. This was an exhaustive survey. All usable consultation and hospitalization registers were included in the study. Non-usable consultation and hospitalization registers were not included. Data were collected from January 1 to December 31 of each respective year. Data were cleaned using Excel before analysis. R software version 4.3.3 was used for analysis. Results: Between 2018 and 2022, 26,029 patients were registered in mental health facilities in Senegal. The Fann Psychiatry Department (CHNU Fann) admitted 23.2% of patients and the Thiaroye National Psychiatric Hospital registered 17.6% of drug users. For the year 2019, we found 8259 and in 2021, we had 6607 patients. The male gender was more represented with 14,750 patients, or 90.9%. The age group [25 - 34] was the majority (7013 patients or 39.5%). The majority of patients (17,425 patients, or 84.6%) were followed as outpatients. The drugs were mainly inhaled (96.7%). The most consumed substance was cannabis with 8847 patients, or 54.2%. Withdrawal was the main reason for treatment, 11,614 patients, or 85.7%. Conclusion: In the light of the results of our study, we can say that the use of psychoactive substances is a real public health and development problem in Senegal. The peaks in psychoactive substance consumption preceded the peaks in psychiatric care centers, so we need to promote information, education and communication on the harmful effects of psychoactive substance consumption among the population in general and young people in particular, in order to safeguard the country’s development.展开更多

The pressure exerted by the work environment demands the utilization of defensive and coping strategies to deal with it. Our study aims to explore the relationship between professional stress factors, stress symptoms, and the consumption of psychoactive substances as a defensive and coping strategy deployed to address psychological distress at work. A qualitative and quantitative study was conducted with a sample of 405 employees from a wiring manufacturing. The main professional stress factors identified were concentration, overload, long working hours, and monotony, which showed a significant correlation with PAS consumption. Women were found to be more affected by stress and tended to consume more sedatives. Among the respondents, 21.98% reported PAS consumption, with tobacco being the most commonly used (M = 2.66), followed by alcohol (M = 1.94), cannabis (M = 1.79), and sedatives (M = 1.45). There was a significant positive correlation between PAS consumption and stress symptoms {tobacco (r = 0.232*), alcohol (r = 0.305**), cannabis (r = 0.389**)}.展开更多

文摘Spider mites are significant pests in agricultural production.The increasing resistance of spider mites,along with environmental pollution and ecological imbalance caused by their control,is primarily attributed to the long-term use of chemical acaricides in agriculture.In contrast,bioactive substances of biological origin offer advantages such as wide availability,environmental friendliness,and low tendency to induce resistance,making them a research hotspot for spider mite control.This review summarizes recent advances in the use of plant-derived active compounds(exemplified by extracts from Veratrum rhizomes),RNA interference(RNAi)technology,and microorganism-derived active substances for controlling spider mites.These bioactive agents exert acaricidal effects by disrupting the nervous system,interfering with metabolic processes,or silencing key genes in mites,demonstrating favorable efficacy and considerable potential for development.However,challenges remain,including poor environmental stability,slow action,high production costs,and insufficient understanding of their effects on non-target organisms.Therefore,future research should focus on the screening and development of novel bioactive substances of biological origin,elucidation of their mechanisms of action,optimization of formulation technologies,and assessment of their ecological safety.These efforts will provide valuable insights for promoting the advancement of bioactive substances and supporting sustainable agricultural development.

The most consumed substance was cannabis with 8847 patients, or 54.2%. Withdrawal was the main reason for treatment, 11,614 patients, or 85.7%. Conclusion: In the light of the results of our study, we can say that the use of psychoactive substances is a real public health and development problem in Senegal. The peaks in psychoactive substance consumption preceded the peaks in psychiatric care centers, so we need to promote information, education and communication on the harmful effects of psychoactive substance consumption among the population in general and young people in particular, in order to safeguard the country’s development.

文摘Based on the energy dissipation caused by consolidation deformation of the porous media under external force and migration of the internal suspended substances,a coupled multiphase-substance flow(CMF)model was established.This model introduced the new concepts,such as particle temperature and particle entropy,to describe energy dissipation at meso-level.This model used a potential energy density function and migration coefficients to establish the corresponding connection between the dissipative force and dissipative flow.This viewpoint unifies the deformation,seepage,and suspended substance migration of geotechnical materials under the framework of granular thermodynamics.It can reflect the evolution of effective stress in the solid matrix of multi-components in a particle-reorganized state,and considers the temperature driving effect.The proposed CMF model is validated using the experimental results under coupled migration of heavy metal ions(HMs)and suspended particles(SPs).The calculation results demonstrated that the CMF model can describe the flow process under the conditions of arbitrary changes in different suspended substance types,injection concentrations,and injection velocities.
文摘In this article,we comment on the article by Zhang et al,which explores the familiarity,awareness,and usage of smart medical care and its correlation with mental health and personality traits.The use of intelligent healthcare technologies in treating mental disorders and substance use disorders shows significant promise,but involves certain challenges,such as limited access,low technological literacy,and privacy concerns.These barriers disproportionately affect deprived populations and individuals with severe mental health conditions.We highlight the positive impact of smart healthcare solutions,such as telemedicine and wearable technologies,on patient engagement,remote monitoring,and treatment adherence.To overcome these challenges,we propose strategies,such as improving user-friendliness,ensuring equitable access to digital interventions,enhancing cybersecurity,and integrating smart healthcare into clinical workflows.Training healthcare providers and developing policies to ensure the ethical use of patient data are essential.When implemented thoughtfully,smart healthcare technologies can revolutionize mental health and substance use disorder treatment,improve patient outcomes,and reduce healthcare inequities.
文摘Work-related stress has become an alarming reality that continues to intensify over the past decades. The pressure exerted by the work environment demands the utilization of defensive and coping strategies to deal with it. Our study aims to explore the relationship between professional stress factors, stress symptoms, and the consumption of psychoactive substances as a defensive and coping strategy deployed to address psychological distress at work. A qualitative and quantitative study was conducted with a sample of 405 employees from a wiring manufacturing. The main professional stress factors identified were concentration, overload, long working hours, and monotony, which showed a significant correlation with PAS consumption. Women were found to be more affected by stress and tended to consume more sedatives. Among the respondents, 21.98% reported PAS consumption, with tobacco being the most commonly used (M = 2.66), followed by alcohol (M = 1.94), cannabis (M = 1.79), and sedatives (M = 1.45). There was a significant positive correlation between PAS consumption and stress symptoms {tobacco (r = 0.232*), alcohol (r = 0.305**), cannabis (r = 0.389**)}.

文摘Fermented sour soup is a unique traditional sour food of the Miao and Dong ethnic groups in China.However,due to the commonly used traditional fermentation,the unstable fluctuation of microbial community often leads to some unpleasant inherent off-flavours in rice sour soup.In this study,the microbial composition and volatile flavour components of off-flavour and normal rice sour soup were examined by high-throughput sequencing and headspace solid-phase microextraction coupled with gas chromatography mass spectrometry.Then,based on Pearson correlation coefficients,the correlations between fungi and bacteria and those between core microorganisms and key volatile flavour components were investigated.The dominant fungal genera included Candida,Dekkera,Pichia,Rhizopus,and Issatchenkia,whereas the dominant bacterial genera included Lactobacillus,Pectinatus,Bifidobacterium,Pseudomonas,and Acetobacter.Compared to normal rice sour soup,off-flavoured rice sour soup contained the significantly increased relative abundance of Candida and the significantly decreased relative abundance of Dkkera.In addition,80 volatile flavour compounds detected in off-flavoured rice sour soup,mainly including esters,acids,and alcohols,were different from those detected in normal rice sour soup.Especially,some substances were only detected in off-flavoured rice sour soup,such as 1-hexanol(68-207μg/kg),butyric acid(20-92μg/kg)and heptanoic acid(12-45μg/kg),which might be the main source of off-flavours.These results provide new ideas and strategies of removing or abating odour from fermented rice sour soup.

文摘Objective To investigate the associations between eight serum per-and polyfluoroalkyl substances(PFASs)and regional fat depots,we analyzed the data from the National Health and Nutrition Examination Survey(NHANES)2011-2018 cycles.Methods Multiple linear regression models were developed to explore the associations between serum PFAS concentrations and six fat compositions along with a fat distribution score created by summing the concentrations of the six fat compositions.The associations between structurally grouped PFASs and fat distribution were assessed,and a prediction model was developed to estimate the ability of PFAS exposure to predict obesity risk.Results Among females aged 39-59 years,trunk fat mass was positively associated with perfluorooctane sulfonate(PFOS).Higher concentrations of PFOS,perfluorohexane sulfonate(PFHxS),perfluorodecanoate(PFDeA),perfluorononanoate(PFNA),and n-perfluorooctanoate(n-PFOA)were linked to greater visceral adipose tissue in this group.In men,exposure to total perfluoroalkane sulfonates(PFSAs)and long-chain PFSAs was associated with reductions in abdominal fat,while higher abdominal fat in women aged 39-59 years was associated with short-chain PFSAs.The prediction model demonstrated high accuracy,with an area under the curve(AUC)of 0.9925 for predicting obesity risk.Conclusion PFAS exposure is associated with regional fat distribution,with varying effects based on age,sex,and PFAS structure.The findings highlight the potential role of PFAS exposure in influencing fat depots and obesity risk,with significant implications for public health.The prediction model provides a highly accurate tool for assessing obesity risk related to PFAS exposure.

文摘Per-and polyfluoroalkyl substances(PFASs)can induce a range of adverse health effects,with the precise molecularmechanisms remaining elusive.Extracellular vesicles(EVs)have demonstrated their potential to elucidate unknown molecular mechanisms.Building upon the close alignment of their biological functions with the observed health effects of PFASs,this study innovatively focuses on proteomic insights from EVs into the molecular mechanisms underlying the systemic health effects of PFASs.Through rat exposure experiments and proteomics technology,it not only demonstrated the occurrence of PFASs in EVs but also revealed the alterations in the serum EVs and the expression of their protein cargos following mixed exposure to PFASs,leading to changes in related pathways.These changes encompass various biological processes,including proteasome activity,immune response,cytoskeletal organization,oxidative stress,cell signaling,and nervous system function.Particularly noteworthy is the uncovering of the activation of the proteasome pathway,highlighting significant key contributing proteins.These novel findings provide a new perspective for exploring the molecularmechanism underlying the systemic health effects of PFASs and offer reliable screening for potential biomarkers.Additionally,comparisons with serum confirmed the potential of serum EVs as biological responders and measurable endpoints for evaluating PFASs-induced toxicity.

文摘Perfluoroalkyl and polyfluoroalkyl substances(PFASs)pollution with their toxicity,carcinogenicity,and persistence has been concerned worldwide.Research into novel materials for detecting and removing PFASs has increased rapidly,particularly in regard to the emergence of well-characterized single-atom materials(SAMs).Owing to the high selectivity,high atom utilization,and abundant active sites of SAMs,these materials exhibit remarkable efficacy in the detection and removal of PFASs.In this work,recent advances in the synthesis of SAMs for the detection and removal PFASs are reviewed.In-depth discussions of the structure-activity relationship and reaction mechanisms have demonstrated the high efficiency,activity,and selectivity of SAMs for the detection,adsorption,and degradation of PFASs.To optimize the application of SAMs in PFASs remediation,this review comprehensively surveys SAMs applications for PFASs and analyzes potential design strategies based on synthesis methods and corresponding properties.Synthesis strategies such as wet-chemistry,which offer ease of operation and high potential for large-scale production,are recommended for the further exploration of specific SAMs for the detection and removal of PFASs.Finally,this review identifies the challenges and opportunities for development of SAMs for the detection and remediation of PFASs,providing an outlook on strategic goals for a green economy and sustainable development.

文摘The optical absorption of large molecular compounds HULIS(humic-like substances)can significantly impact the aerosol light absorption and radiative forcing,influencing cloud condensation nuclei formation and thus the climate and atmospheric environment.This study collected aerosol(PM_(2.5))samples from the summit of Mount Tai in North China to investigate the concentration,molecular composition,and optical properties of HULIS.The average concentration of HULIS in the PM_(2.5) in this study was 1.26±0.54μg/m^(3),comprising for 56%of the water-soluble organic carbon(WSOC),with levels lower than urban areas but higher than other mountainous regions.Mass spectrometry revealed that CHO and CHON components,with high aromaticity and phenolic groups,are major contributors to absorption and fluorescence.These results indicate that HULIS is mainly composed of lignin and proteins/amino sugars,derived from combustion and secondary formation,and possesses a high light absorption capacity(withMAE365(mass absorption efficiency)and AAE(A˚ngstrom exponent)indices of 0.62m^(2)/g and 4.99,respectively).Parallel factor analysis identified three fluorescence components of HULIS,with proportions of 60.8%for less oxygen humic-like substances,21.0%for high oxygen humic-like substances,and 18.2%for protein-like substances.Our study highlights the significance of the light-absorbing capacity and secondary formation of HULIS at Mount Tai,laying the groundwork for investigation into the climate effects,formation mechanisms,and sources of HULIS generation.

文摘Although per-and polyfluoroalkyl substances(PFAS)have been frequently linked to cardiovascular and renal disease separately,evidence remains scarce regarding their systematic effect.Therefore,we recruited 546 newly diagnosed acute coronary syndrome(ACS)patients and detected seven myocardial enzymes and six kidney function biomarkers.Twelve PFASwere also assessedwith ultra-high-performance liquid chromatography-tandem mass spectrometry.Generalized linear model and restricted cubic spline model were applied to single pollutant analysis.Quantile g-computation was used for mixture analysis.Network model was utilized to identify central and bridge nodes of pollutants and phenotypes.In the present study,perfluorohexane sulfonic acid was positively associated with uric acid(UA)(β=0.04,95%confidence interval(CI):0.01,0.07),and perfluorobutanoic acid was negatively associated with estimated glomerular filtration rate(β=-0.04,95%CI:-0.07,-0.01)but positively associated with UA(β=0.03,95%CI:0.01,0.06).In mixture analysis,each quantile increase in the PFAS mixture was significantly associated with UA(β=0.08,95%CI:0.04,0.11).Network analysis revealed that perfluorooctanoate,UA,and myoglobin were denoted as bridge nodes,and the first principal component of lactate dehydrogenase and creatine kinase-myocardial band was identified as the node with the highest strength and expected influence.This study investigates the systematic impact of PFAS exposure through cardiorenal interaction network,which highlights that PFAS may serve as an upstream approach in UA-modulated cardiorenal network to affect cardiorenal system comprehensively.

文摘The current quality standard for polyvinyl alcohol eye drops lacks an impurity assessment,despite the potential impact of raw material impurities on product safety.To strengthen quality control and ensure drug safety,an investigation into the impurity profile of the formulation was conducted,and an HPLC-UV method was developed for impurity quantification.The method validation was performed using an H-type cation exchange column.A total of 116 batches of polyvinyl alcohol eye drops from four manufacturers and two batches of the innovator drug were analyzed.Formic acid was detected exclusively in 0.4 mL samples from Company A and the innovator drug,with concentrations below 0.002%in both cases.Acetic acid was identified in samples from all manufacturers,with levels not exceeding 0.1%.The method demonstrated high specificity and sensitivity,making it well-suited for the quantification of formic and acetic acids in polyvinyl alcohol eye drops.The presence of formic acid was attributed to excipients,whereas acetic acid originated from raw materials and was further generated during pH adjustment in manufacturing.Although the overall impurity levels were low and posed minimal risk to drug safety,manufacturers should remain vigilant regarding impurity control to maintain product quality.

文摘Reclaimed water for irrigation or hydroponic cultivation provides exposure pathways for per-and polyfluoroalkyl substances(PFAS)to enter the human food chain.This study employed hydroponic methods to investigate the behavior of legacy PFAS and emerging chlorinated polyfluoroalkyl ether sulfonic acids(Cl-PFESAs)in lettuce grown under environment-related exposure levels and assessed the human exposure risks from consuming contaminated lettuce.Overall,PFAS in lettuce were concentration-dependent,with long-chain PFAS tending to accumulate in roots and short-chain PFAS accumulating more in shoots.The enrichment of PFAS in lettuce was jointly influenced by their chain length and polar functional groups.Specifically,the root concentration factors(RCFs)of PFAS generally increased with increasing chain length,and RCF values of most perfluoroalkanesulfonic acids(PFSAs)were significantly higher than those of perfluoroalkyl carboxylic acids(PFCAs)with the same chain length(p<0.01),while the translocation factors(TFs)exhibited opposite trends.RCF values of perfluorooctane sulfonate(PFOS)and its alternatives,Cl-PFESAs,were ranked as follows:8:2 Cl-PFESA(mean:139)>6:2 Cl-PFESA(28.6)>PFOS(25.7),which was attributed to the increased molecular size and hydrophobicity resulting from the insertion of ether bonds and additional CF2 in 8:2 Cl-PFESA.Notably,TF value of 8:2 Cl-PFESA(mean:0.007)was the smallest among all PFAS,indicating 8:2 Cl-PFESA was difficult to transfer to nutritional compartments.Adults and children would exceed the most conservative health-based reference dose(RfD)by consuming approximately 15.9–148 g and 7.92–74.0 g of contaminated lettuce per day,implying high health risks.

文摘Previous studies have suggested that abnormal hepatobiliary system function may contribute to poor prognosis in patientswith acute coronary syndrome(ACS)and that abnormal hepatobiliary system function may be associated with per-and polyfluoroalkyl substances(PFAS)exposure.However,there is limited evidence for this association in cardiovascular subpopulations,particularly in the ACS patients.Therefore,we performed this study to evaluate the association between plasma PFAS exposure and hepatobiliary system function biomarkers in patients with ACS.This study included 546 newly diagnosed ACS patients at the Second Hospital of Hebei Medical University,and data on 15 hepatobiliary system function biomarkers were obtained from medical records.Associations between single PFAS and hepatobiliary system function biomarkers were assessed using multiple linear regression models and restricted cubic spline model(RCS),and mixture effects were assessed using the Quantile g-computation model.The results showed that total bile acids(TBA)was negative associated with perfluorohexane sulfonic acid(PFHxS)(-7.69%,95%CI:-12.15%,-3.01%).According to the RCS model,linear associations were found between TBA and PFHxS(P for overall=0.003,P for non-linear=0.234).We also have observed the association between between PFAS congeners and liver enzyme such as aspartate aminotransferase(AST)and α-l-Fucosidase(AFU),but it was not statistically significant after correction.In addition,Our results also revealed an association between prealbumin(PA)and PFAS congeners as well as mixtures.Our findings have provided a piece of epidemiological evidence on associations between PFAS congeners or mixture,and serum hepatobiliary system function biomarkers in ACS patients,which could be a basis for subsequent mechanism studies.
