Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.展开更多

文摘Stock volatility constitutes an adverse psychological stressor,but few large-scale studies have focused on its impact on major adverse cardiovascular events(MACEs)and suicide.Here,we conducted an individual-level time-stratified case-crossover study to explore the association of daily stock volatility(daily returns and intra-daily oscillations for three kinds of stock indices)with MACEs and suicide among more than 12 million individual decedents from all counties in the mainland of China between 2013 and 2019.For daily stock returns,both stock increases and decreases were associated with increased mortal-ity risks of all MACEs and suicide.There were consistent and positive associations between intra-daily stock oscillations and mortality due to MACEs and suicide.The excess mortality risks occurred at the cur-rent day(lag 0 d),persisted for two days,and were greatest for suicide and hemorrhagic stroke.Taking the present-day Shanghai and Shenzhen 300 Index as an example,a 1%decrease in daily returns was associated with 0.74%-1.04%and 1.77%increases in mortality risks of MACEs and suicide,respectively;the corresponding risk increments were 0.57%-0.85%and 0.92%for a 1%increase in daily returns and 0.67%-0.77%and 1.09%for a 1%increase in intra-daily stock oscillations.The excess risks were more pro-nounced among individuals aged 65-74 years,males,and those with lower education levels.Our findings revealed considerable health risks linked to sociopsychological stressors,which are helpful for the gov-ernment and general public to mitigate the immediate cardiovascular and mental health risks associated with stock market volatility.

文摘Falls represent a significant public health issue worldwide.Previous studies have demonstrated associations of temperature with fall risk,but the effect and burden of hourly relative humidity and fall morbidity have been rarely investigated.Fall data and meteorological data were collected from the National Injury Surveillance System during 2006−2021 in China.Associations between hourly relative humidity and fall onset were analyzed using conditional logistic regression combined with a distributed lag nonlinear model.Stratified analysis was used to identify potential association modifiers.Several sensitivity analyses were applied to examine the robustness of the results.The study involved 4197495 fall-related cases.Relative humidity exhibited monotonic relationships with the fall onset risk.The excess risk(ER)of falls appeared immediately at lag 0 h and persisted for 8 h.A 10%decrease in relative humidity was associated with a 1.35%(95%confidence interval[CI]:0.83−1.87%)increase in excess risk of falls and much higher risk for males(ER=1.89%,95%CI:1.29−2.48%)than that for females(ER=0.52%,95%CI:0.14−0.90%).The excess risk of fall injury was the highest among individuals aged 5−14 years(ER=3.45%,95%CI:2.57−4.32%)compared to other age groups.Moreover,compared to the highest relative humidity,the attributable fraction(AF)due to low relative humidity exposure was 4.94%(95%CI:4.88−4.98%).Subgroup analyses revealed that males,individuals aged 5−14 years,students,cases occurring in public places,and cases engaged in sports activities were more susceptible to relative humidity than their correspondents.Regional disparities were observed,with individuals in southern China or warm regions showing greater sensitivity to changes in relative humidity.Results of this study suggest that hourly low relative humidity exposure is associated with an increased risk of fall onset.These findings underscore the necessity of time-specific interventions to mitigate the relative humidity risk.

文摘Few studies have explored the acute effects of fine particulate matter(PM_(2.5))constituents on respiratory diseases(RDs),particularly across a broad spectrum of RD subtypes.We analyzed the associations between PM_(2.5) and its five major constituents[organic matter(OM),black carbon(BC),sulfate(SO_(4)^(2−)),nitrate(NO_(3)^(−)),and ammonium(NH_(4)^(+))]and RDs(10 major categories and 35 specific)based on the hospitalization records from 153 hospitals in 20 provincial distractions from 2013 to 2020.We found that short-term exposure(lag 0−1)to PM_(2.5) constituents per interquartile range increase was associated with higher hospitalization risks for acute upper respiratory infections,influenza and pneumonia,other acute lower respiratory infections,chronic lower respiratory diseases,other diseases of the pleura,and other diseases of the respiratory system;the effect estimates were 2.45−2.99%,2.02−2.71%,2.98−3.62%,3.06−3.65%,3.22−4.52%,and 2.23−3.66%,respectively.Among 35 specific RDs,12 were significantly affected by PM_(2.5) and its constituents.Individuals aged>60 years were sensitive to PM_(2.5) constituent exposure.Our individual-level nationwide study provided a more comprehensive perspective on the associations between PM_(2.5) constituents and various major and specific RDs,highlighting the necessity of prioritizing targeted control strategies for key constituents to effectively mitigate the burden of RDs in China.

文摘Few national studies have systemically examined the effects of criteria air pollutants on cardiovascular morbidity.This study aimed to investigate the associations between all criteria air pollutants and hospitalization of causespecific cardiovascular diseases(CVD)in China.We obtained data on CVD hospitalization events of four major categories and 12 specific diseases from 153 hospitals distributed in 20 provincial-level regions from 2013 to 2020.We adopted a time-stratified case-crossover study design using individual cases to capture the effect of short-term exposure to six criteria air pollutants on CVD hospitalizations,using conditional logistic regression models.More than 1.1 million CVD hospitalization events were included.The lag pattern exploration demonstrated the largest effect for six air pollutants on lag 0–1 day.PM_(2.5),PM_(10),NO_(2),and CO were significantly associated with increased hospitalization from ischemic heart diseases,cerebrovascular diseases,other heart diseases,and five specific causes of CVD.The effect estimates of NO_(2)were the most robust when adjusting for copollutants.The concentration-response curves were positive and linear for most pollutant–endpoint pairs(except for O_(3)),and these positive associations remained even below the 24-h levels recommended by WHO Air Quality Guidelines and China Air Quality Standards.This nationwide case-crossover study in China demonstrated that short-term exposure to multiple ambient air pollutants may significantly increase the risk of cause-specific CVD hospitalizations even under the most stringent air quality regulations,striking an alert for potential CVD patients against these environmental risk factors.

文摘Incident chronic kidney disease(CKD)may be accelerated(could be indicated by repeated admissions to the hospital)by environmental triggers such as ambient particulate matter(PM).Additionally,hospital admission is a sensitive proxy reflecting the disease burden.However,the association of PM exposure with hospital admissions for CKD is still unknown,let alone the excess risks(ERs)in hospital admissions for CKD due to high PM level exposure.In this study,a two-stage time-stratified case-crossover study was conducted to investigate the association of ambient air PM exposure with hospital admission for CKD in 282 Chinese cities of prefecture-level or above during 2013–2017.City-specific associations of single and cumulative 0–3 days lagged exposure to fine particulate matter(PM_(2.5))and inhalable particles(PM_(10))with hospital admissions for total CKD and its subtypes were evaluated by the conditional logistic regression model,then were pooled using the random-effect model.A total of 3,490,416 hospital admissions for CKD were identified.We found that per interquartile range(IQR)increment in PM_(2.5) at lag02 and per IQR increment in PM_(10) at lag03 were associated with increases of 2.36%(95%CI:1.58%,3.14%)and 2.87%(95%CI:1.91%,3.85%)in hospital admissions for total CKD,respectively.Compared to control concentrations(PM_(2.5):35μg/m^(3);PM_(10):50μg/m^(3)),the largest ERs in hospital admissions for total CKD were 2.63%(95%CI:2.15%–3.11%)and 4.45%(95%CI:3.85%–5.06%)in association with exposure to heavily excessive PM_(2.5)(≥75μg/m^(3))and PM_(10)(≥150μg/m^(3)),respectively.Moreover,the attributable fractions(AFs)for CKD admissions were 2.83%for PM_(2.5) and 3.46%for PM_(10) during the study period.These findings suggested that exposure to PM_(2.5) and PM_(10) is associated with substantially increased risk and burden of CKD admissions.
文摘BACKGROUND Gastrointestinal endoscopy technology has significantly improved the diagnostic accuracy and the successful treatment of gastrointestinal diseases.However,a series of ethical issues have emerged,such as expanding treatment indications,which affect the fair distribution of medical resources.There is limited research on ethical issues in the field of digestive endoscopy.AIM To investigate the level of ethical awareness among gastrointestinal endoscopy practitioners and analyze the ethical issues involved in gastrointestinal endoscopy technology.METHODS A questionnaire survey was performed to collect relevant data(gender,age,degree of education,professional title,personnel category,the level of understanding medical ethical principles,ethics training and its learning pathways)from gastrointestinal endoscopy practitioners at the Second Hospital of Dalian Medical University and Dalian Friendship Hospital,including licensed physicians and nurses(including trainees and graduate students).RESULTS The majority of gastrointestinal endoscopy practitioners have received training on ethics,but there is still considerable room for improvement in their ethical awareness.Different learning pathways may affect the mastery of ethical principles, and understanding of ethical principles is more easily achieved through hospital ethics institutions.CONCLUSIONTo address the ethical issues in gastrointestinal endoscopy technology, it is necessary to enhance the humanisticeducation of gastrointestinal endoscopy practitioners, incorporate ethical standards into the technology assessmentprocess, and establish a patient-centered diagnostic and treatment model to improve the ethical awareness of practitionersand achieve a balance between technology and ethics.

文摘Existing evidence suggests residential greenness is beneficial to human,while no research to date explored the associations of greenness with age-related macular degeneration(AMD).To evaluate the association of greenness with AMD,modification and mediation effect of air pollution,we conducted this prospective study.We con-structed weighted quantile sum(WQS)index as co-exposure to nitrogen oxides(NO_(x)),particulate matter<2.5μm(PM_(2.5)),particulate matter<10μm(PM10).Stratified Cox regression models were applied to test the effect of exposure.Effect modification of air pollution was assessed.Stratified Cox models through the indirect method and Aalen additive risk models were used in mediation analysis.Over median follow-up of 11.67 years,4596 AMD events were ascertained.Hazard ratios(HRs)and 95%confidence intervals(95%CIs)of incident AMD for pollution per interquartile range(IQR)increment were 1.10(1.04–1.16)for nitrogen dioxide(NO_(2)),1.09(1.03–1.15)for NO_(x),1.14(1.05–1.24)for PM_(2.5),1.13(1.05–1.21)for PM10.The HR(95%CI)of AMD associated with greenness 1000 m buffer per IQR increment was 0.91(0.86–0.97),300 m buffer was 0.94(0.89–0.99).The as-sociation between greenness 1000 m and AMD was 28.59%,44.77%,35.59%,32.31%and 27.08%mediated by the decreased WQS index,NO_(2),NO_(x),PM_(2.5) and PM10,respectively.Increased greenness was associated with lower AMD incidence,and air pollution partly mediate it,which implies that interventions aimed at improving air quality and increasing greenness could have a dual benefit in mitigating AMD risk.
文摘Background:Despite highly effective vaccines against SARS-CoV-2,COVID-19 vaccine hesitancy persisted in some populations in England during the pandemic,with rates and motivations for hesitancy varying by demographic group.Addressing the drivers of vaccine hesitancy through targeted interventions in hesitant groups is a public health priority for better and more rapid control of disease spread.We aimed to characterise the determinants and subtypes of vaccine hesitancy and identify more persistent forms of hesitancy via analysis of vaccine uptake in a large cross-sectional cohort with linked National Health Service(NHS)data.

文摘Background:To determine whether initiating a glucagon-like peptide-1 receptor agonist(GLP-1 RA)within 3 months of type 2 diabetes(T2DM)diagnosis alters the subsequent risk of overall and site-specific cancer and whether this association differs by baseline body-mass index(BMI).Methods:This retrospective cohort study used electronic health records from the TriNetX U.S.research network.Adults aged 20 years or older diagnosed with T2DM between 2016 and 2024 were included if they received any hypoglycemic agents within 3 months before and after diagnosis.Following 1:1 propensity score matching,both the GLP-1 RA user and non-user groups included 183,264 patients.The study outcome was defined as a diagnosis of malignant neoplasms.Hazard ratios(HRs)for overall and site-specific cancer risk were estimated using Cox proportional hazards models.Kaplan–Meier analysis and stratified analysis by BMI were performed.Results:Early GLP-1 RA use demonstrated a modest but significant association with reduced overall cancer risk(HR 0.93;95%CI:0.90–0.96).Reduced risks were noted for cancers of the digestive(HR 0.81),respiratory(HR 0.66),and female genital(HR 0.87)systems.In stratified analysis,benefits were more pronounced in patients with BMI≥30,particularly for pancreatic and colorectal cancers.Conclusion:Early initiation of GLP-1 receptor agonists in patients with diagnosed T2DM was associated with a modest reduction in overall cancer risk,particularly among individuals with obesity.These findings highlight the dual metabolic and oncologic value of prompt GLP-1 RA therapy.

文摘Aim： To compare the use of the suprapubic puncture method versus the transurethral method in pressure-flow studies in patients with benign prostatic hyperplasia. Methods： Twenty-three men with benign prostatic hyperplasia underwent both suprapubic and transurethral pressure-flow studies during a single session. Standard pressure-flow variables were recorded in all patients with both methods, enabling calculation of obstruction using commonly used grading systems, such as the urethral resistance algorithm, the Abrams-Griffith （AG） number and the Schaefer linear nomogram. Results： There were statistically significant differences between the methods in the mean values of maximum flow rate （P 〈 0.05）, detrusor pressure at the maximum flow （P 〈 0.01）, urethral resistance algorithm （P 〈 0.01）, AG number （P 〈 0.01） and maximum cystic capacity （P 〈 0.01）. Of the men in the study, 10 （43.5%） remained in the same Schaefer class with both methods and 18 （78.3%） in the same AG number area. Using the transurethral method, 12 （52.2%） men increased their Schaefer class by one and 1 （4.3%） by two. There were also differences between the suprapubic and transurethral methods using the AG number： 4 （17.4%） men moved from a classification of equivocal to obstructed and 1 （4.3%） from unobstructed to equivocal. Conclusion： The differences between the techniques for measuring intravesical pressure alter the grading of obstruction determined by several of the commonly used classifications. An 8 F transurethral catheter significantly increases the likelihood of a diagnosis of bladder outlet obstruction when compared with the suprapubic method.
文摘BACKGROUND Previous systematic reviews have consistently reported that coffee consumption has a preventive effect on the occurrence of type 2 diabetes mellitus(T2DM).However,further evaluations between coffee consumption and the risk of T2DM in Asian populations are needed.AIM To conduct a meta-epidemiological study on systematic reviews evaluating the association between coffee consumption and the risk of T2DM in Asian people.METHODS The selection criterion was defined as a population-based prospective cohort study evaluating the association between coffee consumption and the risk of T2DM in Asian populations,reporting the adjusted relative risk(RR)and its 95%confidence interval(CI)for potential confounders.A fixed-effect model metaanalysis was applied to calculate the summary RR and its 95%CI in less than 50%of the I2 value indicating the level of heterogeneity.A two-stage fixed-effects doseresponse meta-analysis(DRMA)was performed to calculate the risk per unit dose(a cup per day).RESULTS A total of seven studies were selected in this meta-epidemiological study.The risk of T2DM in Asian populations was significantly reduced in the highest to the lowest dose group(summary RR=0.73,95%CI:0.66-0.82;I2 value=0.0%).The DRMA showed that drinking one cup of coffee per day reduced the risk of T2DM in Asian populations by 8%(RR=0.92,95%CI:0.90-0.95).CONCLUSION These findings support the conclusion that coffee consumption has a protective effect on the occurrence of T2DM in Asian men and women.

文摘Randomized controlled trials(RCTs) are the gold standard in terms of study design, however, in the surgical setting conducting RCTs can often be unethical or logistically impossible. Case-control studies should become the major study design used in surgical research when RCTs are unable to be conducted and definitely replacing case series which offer little insight into surgical outcomes and disease processes.
