Our findings indicate that about three-fifths of the sample H II regions reside within the regime occupied by local star-forming galaxies(SFGs) along the dust attenuation correlation described by their corresponding color excess parameters E(B-V)IRX= 0.51 E(B-V)Hα/Hβ. Nearly 27% of the sample exhibits E(B-V)IRX> E(B-V)Hα/Hβ, while a small fraction(~13%) displays significantly lower E(B-V)IRXcompared to E(B-V)Hα/Hβ. These results suggest that the correlation between the two dust attenuation indicators no longer holds for spatially resolved H II regions. Furthermore, the ratio of E(B-V)IRXto E(B-V)Hα/Hβremains unaffected by various physical parameters of the H II regions, including star formation rate(SFR), SFR surface density, infrared luminosity(LIR),LIRsurface density, stellar mass, gas-phase metallicity, circularized radius, and the distance to the galactic center.We argue that the ratio is primarily influenced by the evolution of the surrounding interstellar medium of the starforming regions, transitioning from an early dense and thick phase to the late blown-away stage.展开更多

An accurate model to estimate, as a function of time, these default probabilities is of crucial importance in the credit derivatives market. In this work, we adapt Merton’s [1] original works on credit risk, consumption and portfolio rules to model an individual wealth scenario, and apply it to compute this individual default probabilities. Using our model, we also compute the time depending individual default intensities, recovery rates, hazard rate and risk premiums. Hence, as a straight-forward application, our model can be used as novel way to measure the credit risk of individuals.展开更多

文摘Objectives:This study aimed to determine the effectiveness of an individual and family selfmanagement(IFSM)education program on triglyceride-glucose(TyG)index,self-management,and diabetes distress among adults with uncontrolled diabetes mellitus type 2(T2DM).Methods:A multicentre randomized controlled trial was employed.The study included 68 dyads(adults with uncontrolled T2DM and one family member)that were randomly allocated to the intervention(n=34)and control groups(n=34)from March to September 2024.Participants in the intervention group received an 8-week IFSM education program,whereas those in the control group received standard routine care.An automated hematology analyzer XP-100 was used to evaluate triglyceride and fasting blood glucose levels.The Diabetes Distress Scale and Diabetes Self-Management Questionnaire were used to measure diabetes distress and self-management,respectively.Results:A total of 67 participants completed the intervention.The generalized estimating equation demonstrated a significantinteraction between group and time.The IFSM education intervention group had a higher diabetes self-management(β=16.68;95%CI=15.23,18.09;P<0.001),lower diabetes distress(β=-30.74;95%CI=-32.57,-28.90;P<0.001),and lower TyG index(β=-1.97;95%CI=-2.41,-1.53;P<0.001)than the control group.Conclusions:The findingsdocumented the capacity of IFSM education to reduce TyG and diabetes distress,which could potentially escalate diabetes self-management among individuals with T2DM.
文摘Background:Oral health issues persistently affect the overall health and well-being of rural populations.Village health volunteers(VHVs)play a crucial role in advancing oral health literacy in their community.This study aimed to examine the factors related to nutritional literacy for oral health among VHVs.Methods:This was a mixed-methods study employing an explanatory sequential design.The quantitative data were gathered through questionnaires distributed to a cohort of 10,514 VHVs registered in Health Region 1.A stratified random sampling technique was used to ensure adequate representation of various subgroups within the VHV population,considering factors such as age,education level,and geographical distribution across the region.This approach allowed for a more representative sample that accurately reflects the diversity of the VHV population.Qualitative data were obtained through semi-structured interviews with a purposive sampling of 20 participants based on specific criteria.Quantitative data were analyzed using descriptive statistics and biserial correlation techniques,while qualitative data were analyzed using content analysis.Results:The study found that the sample group possessed a moderate level of knowledge of health literacy principles and nutrition for oral health.However,their self-assessed skills in nutritional literacy for oral health were rated as high.A statistically significant negative correlation was found between knowledge of nutrition for oral health and skills in nutritional literacy for oral health.VHVs equated health literacy with knowledge because their public health training had focused more on imparting knowledge rather than developing skills based on health literacy principles.Conclusion:There is a need to emphasize skill-based health literacy training and to use effective skill development techniques that are tailored to the specific roles and responsibilities of health volunteers.It is also recommended to continuously monitor and evaluate the outcomes of these efforts.

文摘Light hydrocarbons(LHs)are key components of petroleum,and the carbon isotopes composition(δ^(13)C)of individual LHs contains a wealth of geochemical information.Forty-four oil samples from five different basins were analyzed using gas chromatography(GC),gas chromatography-mass spectrometry(GC–MS),and gas chromatography-isotope ratio mass spectrometry(GC-IRMS).Theδ^(13)C values of forty-three LHs were recognized and determined by comparing the GC and GC-IRMS methods.The results revealed significant differences inδ^(13)C distribution characteristics among different LH compounds.Theδ^(13)C variation of individual LHs in iso-paraffins showed the widest range,followed by cycloalkanes and aromatics,whereas theδ^(13)C variation in n-paraffins showed the narrowest range.Theδ^(13)C values of most individual LHs are primarily affected by the source facies and thermal evolution.Among them,c-1,3-dimethylcyclohexane(c-1,3DMCH)is mainly sourced from higher plants but may also form through abiotic mechanisms such as catalysis or cyclization.Theδ^(13)C values of c-1,3DMCH(δ^(13)Cc-1,3DMCH)primarily exhibit parental genetic characteristics,enabling effective distinction of oil from different source facies.Specifically,theδ^(13)Cc-1,3DMCH in marine oils,lacustrine oils,terrigenous oils,and coal-formed oils are<–22‰,from–22‰to−20.2‰,from−20.2‰to−18.4‰,and>−18.4‰,respectively.Moreover,maturity is the primary controlling factor forδ^(13)C values of 3MC7(δ^(13)C3MC7,3MC7:3-methylheptane),while the source facies serve as a secondary influence.The plot ofδ^(13)Cc-1,3DMCH andδ^(13)C3MC7 was introduced to classify source facies.Asδ^(13)Cc-1,3DMCH andδ^(13)C3MC7 increase,the source facies transits from marine to lacustrine,then terrigenous,and finally coal facies.Additionally,increasingδ^(13)C3MC7 indicates a relative increase in maturity.Therefore,theδ^(13)Cc-1,3DMCH vs.δ^(13)C3MC7 plot serves as an effective tool for distinguishing source facies and assessing relative maturity.

文摘Background There is insufficient evidence to provide recommendations for leisure-time physical activity among workers across various occupational physical activity levels.This study aimed to assess the association of leisure-time physical activity with cardiovascular and all-cause mortality across occupational physical activity levels.Methods This study utilized individual participant data from 21 cohort studies,comprising both published and unpublished data.Eligibility criteria included individual-level data on leisure-time and occupational physical activity(categorized as sedentary,low,moderate,and high)along with data on all-cause and/or cardiovascular mortality.A 2-stage individual participant data meta-analysis was conducted,with separate analysis of each study using Cox proportional hazards models(Stage 1).These results were combined using random-effects models(Stage 2).Results Higher leisure-time physical activity levels were associated with lower all-cause and cardiovascular mortality risk across most occupational physical activity levels,for both males and females.Among males with sedentary work,high compared to sedentary leisure-time physical activity was associated with lower all-cause(hazard ratios(HR)=0.77,95%confidence interval(95%CI):0.70-0.85)and cardiovascular mortality(HR=0.76,95%CI:0.66-0.87)risk.Among males with high levels of occupational physical activity,high compared to sedentary leisure-time physical activity was associated with lower all-cause(HR=0.84,95%CI:0.74-0.97)and cardiovascular mortality(HR=0.79,95%CI:0.60-1.04)risk,while HRs for low and moderate levels of leisure-time physical activity ranged between 0.87 and 0.97 and were not statistically significant.Among females,most effects were similar but more imprecise,especially in the higher occupational physical activity levels.Conclusion Higher levels of leisure-time physical activity were generally associated with lower mortality risks.However,results for workers with moderate and high occupational physical activity levels,especially women,were more imprecise.Our findings suggests that workers may benefit from engaging in high levels of leisure-time physical activity,irrespective of their level of occupational physical activity.

文摘Animals can differ in their individual movement behaviors during their daily displacements.Studies of animal movement patterns often disregard the need to understand individual variation in these patterns and the role of this variation in shaping population distributions of movements.To assess the link between individual movements and population distributions,we radio-tracked 13 Fowler's Toads Anaxyrus fowleri in Long Point,Ontario,Canada,after their breeding season.We recorded individual coordinates every 30 min,from the moment they emerged from their burrows around dusk until they burrowed in the morning,and obtained a total of 157 movements.We used the resulting series of step lengths and turning angles in a Hidden Markov Model to estimate movement type as"directed"or"non-directed"We also assigned to each encounter one of 3 space-dependent movement states:"foraging""in transit'or"searching"and found that movement type and state switched within individuals irrespective of time during a single night.We find that switching between movement types varied throughout the night,leading to stochastic within-individual variation in movements,and the distribution of movement distances differed significantly among individuals.Movement states,however,were time-dependent,suggesting displacement routines were similar across individuals.Variation in movement behavior within individuals scales up to result in variation among individuals which,in turn,was found to shape the distribution of the sampled population.Our findings therefore underline the importance of a multi-scale approach in the study of movement.

文摘Vocal individuality is essential for social discrimination but has been poorly studied in animals that produce communal signals(duets or choruses).Song overlapping and temporal coordination make the assessment of individuality in communal signals more complex.In addition,selection may favor the accurate identifcation of pairs over individuals by receivers in year-round territorial species with duetting and long-term pair bonding.Here,we studied pair and individual vocal signatures in the polyphonal duets of rufous horneros Furnarius rufus,a Neotropical bird known for its long-term pair bonds.Hornero partners engage in duets to deter territorial intruders and protect their partnership year-round and can discern duets from neighbors versus strangers.Using a dataset of 471 duets from 43 pairs in 2 populations,we measured fne-scale acoustic features across different duet levels(e.g.,complete duets to non-overlapping syllable parts)and analysis levels(pair or individual).Permuted linear discriminant function analyses classifed pairs and individuals more accurately than expected by chance(means:45%and 47%vs.4 and 2%).Pair identity explained more variance in the multivariate acoustic features of duets than individual or population identities.The initial frequency of the duet showed strong potential for encoding pair identity.The acoustic traits contributing most to individual vocal signatures varied between sexes,which might facilitate the simultaneous assessment of duetters’identities by receivers.Our study indicates that vocal individuality may exist even in species with intricate and innate communal signals and elucidates the mechanisms employed by horneros in their social discrimination ability.

文摘We investigate the relationships between infrared excess(IRX = LIR/LUV) and Balmer decrement(Hα/Hβ) as indicators of dust attenuation for 609 H II regions at scales of ~50–200 pc in NGC 628, utilizing data from AstroSat, the James Webb Space Telescope(JWST) and Multi Unit Spectroscopic Explorer. Our findings indicate that about three-fifths of the sample H II regions reside within the regime occupied by local star-forming galaxies(SFGs) along the dust attenuation correlation described by their corresponding color excess parameters E(B-V)IRX= 0.51 E(B-V)Hα/Hβ. Nearly 27% of the sample exhibits E(B-V)IRX> E(B-V)Hα/Hβ, while a small fraction(~13%) displays significantly lower E(B-V)IRXcompared to E(B-V)Hα/Hβ. These results suggest that the correlation between the two dust attenuation indicators no longer holds for spatially resolved H II regions. Furthermore, the ratio of E(B-V)IRXto E(B-V)Hα/Hβremains unaffected by various physical parameters of the H II regions, including star formation rate(SFR), SFR surface density, infrared luminosity(LIR),LIRsurface density, stellar mass, gas-phase metallicity, circularized radius, and the distance to the galactic center.We argue that the ratio is primarily influenced by the evolution of the surrounding interstellar medium of the starforming regions, transitioning from an early dense and thick phase to the late blown-away stage.
文摘BACKGROUND Magnetic resonance imaging(MRI)and endoscopic ultrasonography(EUS)are recommended in combination for screening pancreatic cancer in high-risk individuals.However,in clinical practice,MRI and EUS are increasingly utilized for pancreatic surveillance during routine health examinations.AIM To investigate the feasibility of these imaging modalities for screening in low-risk individuals.METHODS This retrospective study included patients at low risk for pancreatic cancer who underwent MRI or EUS at two health evaluation centers between March 2019 and December 2024.Basic characteristics,laboratory data,and imaging results were collected.RESULTS A total of 3364 low-risk individuals underwent pancreatic screening:1553(46.1%)received MRI,and 1811 underwent EUS.No significant differences were observed in age or sex distribution between the groups.In imaging screening,EUS demonstrated a higher detection rate of abnormal pancreatic lesions(12.8%vs 2.6%;P<0.001).MRI detected more cystic lesions than did EUS(P<0.001).EUS identified smaller nodular lesions compared to MRI(9.2 mm vs 18.0 mm;P=0.044).The MRI group had a higher number of confirmed intraductal papillary mucinous neoplasms(P=0.031),whereas the EUS group identified more suspected branch-duct intraductal papillary mucinous neoplasms(P<0.001).Pancreatic adenocarcinoma was found in three patients(0.08%),with no significant difference in detection rates between EUS and MRI(0.11%vs 0.06%;P=0.656).CONCLUSION In low-risk individuals,MRI and EUS offer comparable effectiveness for pancreatic cancer surveillance.The choice of imaging strategy for health evaluation depends on cost considerations and degree of invasiveness.
文摘Atrial fibrillation(AF)is a growing global health burden,with a prevalence of over 52.55 million cases.Rising disability-adjusted life-years,increasing age,and disparities in care have contributed to the worsening severity and mortality of AF.Modifiable risk factors,such as hypertension,obesity,and diabetes mellitus,are associated with alterations in gut microbiota,making the gut-heart axis a potential therapeutic target.Gut dysbiosis influences AF pathogenesis through inflam-mation,metabolic disruption,and autonomic dysfunction.Key mechanisms include gut barrier dysfunction,short-chain fatty acid(SCFA)depletion,lipopoly-saccharides(LPS)-induced inflammation,and ferroptosis-mediated atrial remodeling.Trimethylamine N-oxide,bile acids,and tryptophan metabolites contribute to arrhythmogenic remodeling.Emerging evidence suggests that dietary interventions,including prebiotics and probiotics,as well as gut surveillance,may help mitigate AF progression.Clinical implications of gut modulation in AF include person-alized dietary strategies,microbiome assessment through metagenomic sequencing,and targeted interventions such as SCFA-based therapies and ferroptosis inhibition.Metabolite surveillance,including LPS and indoxyl sulfate monitoring,may influence the effectiveness of anticoagulant and antiarrhythmic therapy.Despite growing mechanistic evidence linking gut dysbiosis to AF,clinical applications remain unexplored.This review summarizes the current understanding of the gut microbiome's role in AF.

文摘Objective Telomere length is a key aging biomarker,but its sex-specific impact on individualized life expectancy remains uncertain.This study explores sex differences in leukocyte telomere length(LTL)and individualized expected years of life lost(YLL).Methods A prospective cohort of 445,399 participants(203,731 males and 241,668 females)from the UK Biobank was analyzed.LTL values were log-transformed,and YLL was calculated using life tables.Multiple linear regression was applied to examine sex-specific associations.Results In males,each standard deviation(S.D.)increase in LTL was linked to a 0.965-year decrease in YLL(95%CI:–1.025,–0.900;P<0.001).In females,longer LTL was related to a 0.102-year increase in YLL(95%CI:0.057,0.146;P<0.001).Among postmenopausal females,LTL showed a protective effect similar to that in males(0.387-year decrease,95%CI:−0.446,–0.328;P<0.001),while premenopausal females exhibited a detrimental association(0.705-year increase,95%CI:0.625,0.785;P<0.001).Comparable trends were observed across major aging-related diseases,pointing to a consistent biological pattern.Conclusion The influence of LTL on life expectancy varies significantly by sex,with protective associations seen in males and postmenopausal females.This suggests hormonal involvement in telomere dynamics.The results support integrating sex-specific perspectives into aging and telomere research and clinical practice.

文摘Default Probabilities quantitatively measures the credit risk that a borrower will be unable or unwilling to repay its debt. An accurate model to estimate, as a function of time, these default probabilities is of crucial importance in the credit derivatives market. In this work, we adapt Merton’s [1] original works on credit risk, consumption and portfolio rules to model an individual wealth scenario, and apply it to compute this individual default probabilities. Using our model, we also compute the time depending individual default intensities, recovery rates, hazard rate and risk premiums. Hence, as a straight-forward application, our model can be used as novel way to measure the credit risk of individuals.
