    小脑卒中由于出血或水肿有很高的发病率和死亡率,导致后颅窝压力增加。这项回顾性队列研究分析了小脑卒中后的三个结局:住院死亡率,住院时间,和总住院费用。它使用来自国家住院患者样本(NIS)的数据,旨在确定小脑卒中患者预后的预测因素。包括464324名病人,18岁及以上,2010年至2015年在美国小脑卒中医院住院。在我们的研究中,年龄超过59岁的每十年增加,死亡率显著增加;年龄在80岁以上的人群死亡率为5.65(95%CI:5.32-6.00;P<0.0001).存活出院的患者和未存活出院的患者之间观察到患者特征的显着差异,包括年龄较大(77.4vs.70.3年;P<0.0001),女性(58%vs.52%;P<0.0001),并从另一家医疗机构转移(17%与10%;P<0.0001)。直接入院而不是通过急诊科入院的患者更有可能死亡(29%vs.16%;P<0.0001)。黑人的死亡率较低(OR:0.75;P<0.0001),西班牙裔(OR:0.91;P=0.005),和亚洲人(OR:0.89;P=0.03),与白人相比,与男性相比,女性,在地理上,在所有其他地区(中西部,南,和西部)与东北形成鲜明对比。小脑卒中的发病率和高死亡率见于传统卒中带。死亡率也受到疾病严重程度的影响,并随着Charlson合并症指数(CCI)的增加而增加,所有患者精细诊断相关组(APR-DRG)评分,间接地通过接受护理的地方,停留时间(LOS)住宿成本,保险类型,和急诊科入院。LOS随着年龄的增长而增加,在东北的男性中,和其他种族相比,白人更少。趋势分析表明,从2010年到2015年,LOS和成本都有所下降。非白人的成本增加,男性,基于邮政编码的更高的家庭收入,被医疗补助覆盖,转账,CCI≥5,并在美国西部出院。基于患者邮政编码的家庭收入中位数在生活者和死亡者之间平衡良好(P=0.091)。然而,支付者在两组间分布不均匀(总体比较P<0.0001).与住院死亡率相关的出院比例更高(70%vs.65%的死者与活着的团体,分别)。如果有商业保险或自付费用,则出院与死亡相关的较少(15%vs.19%的商业保险和3%与5%为自掏腰包)。住院死亡率与住院时间较长相关(5.6天vs.4.5天;P<0.0001)和更高的成本(16,815美元与11,859美元;P<0.0001)。与较低总成本显著相关的变量是年龄较大,有商业保险,自付或其他付款人,没有通过急诊科入院,具有较低的共病指数(CCI=1-2),从中小型医院出院,位于中西部或南部,和/或非教学(农村或城市)。
    Cerebellar strokes have high morbidity and mortality due to bleeding or edema, leading to increased pressure in the posterior fossa. This retrospective cohort study analyzed three outcomes following a cerebellar stroke: in-hospital mortality, length of hospital stay, and total hospitalization costs. It uses data from the National Inpatient Sample (NIS) and aims to identify the predictors of outcomes in cerebellar stroke patients, including 464,324 patients, 18 years of age and older, hospitalized between 2010 and 2015 in US hospitals with cerebellar strokes. In our study, for every decade age increased beyond 59 years, there was a significant increase in mortality; those aged 80+ years had 5.65 odds of mortality (95% CI: 5.32-6.00; P < 0.0001). Significant differences in patient characteristics were observed between patients who survived to discharge and those who did not, including older age (77.4 vs. 70.3 years; P < 0.0001), female sex (58% vs. 52%; P < 0.0001), and being transferred from another healthcare facility (17% vs. 10%; P < 0.0001). Patients admitted directly rather than through the emergency department were more likely to die (29% vs. 16%; P < 0.0001). The mortality rate was lower for blacks (OR: 0.75; P < 0.0001), Hispanics (OR: 0.91; P = 0.005), and Asians (OR: 0.89; P = 0.03), as compared to the white population, for females in comparison to males, and geographically, in all other areas (Midwest, South, and West) in contrast to the Northeast. Cerebellar stroke incidence and high mortality were seen in the traditional stroke belt. Mortality is also affected by the severity of the disease and increases with the Charlson Comorbidity Index (CCI), All Patient Refined Diagnosis Related Groups (APR-DRG) scores, and indirectly by place of receiving care, length of stay (LOS), cost of stay, type of insurance, and emergency department admissions. LOS increased with age, in males in the Northeast, and was less in whites compared to other races. Trend analysis showed a decrease in LOS and costs from 2010 to 2015. Increased costs were seen in non-whites, males, higher household income based on zip code, being covered under Medicaid, transfers, CCI ≥ 5, and discharges in the western US. Median household income based on the patient\'s zip code was well-balanced between those who lived and those who died (P = 0.091). However, payers were not evenly distributed between the two groups (P < 0.0001 for the overall comparison). A higher proportion of discharges associated with in-hospital mortality were covered under Medicare (70% vs. 65% in the died vs. lived groups, respectively). Fewer discharges were associated with death if they were covered by commercial insurance or paid for out-of-pocket (15% vs. 19% for commercial insurance and 3% vs. 5% for out-of-pocket). In-hospital mortality was associated with a longer length of hospital stay (5.6 days vs. 4.5 days; P < 0.0001) and higher costs ($16,815 vs. $11,859; P < 0.0001). Variables that were significantly associated with lower total costs were older age, having commercial insurance, paying out-of-pocket or other payers, not being admitted through the emergency department, having a lower comorbidity index (CCI = 1-2), and being discharged from a hospital that was small- or medium-sized, located in the Midwest or South, and/or was non-teaching (rural or urban).

    先前的研究表明,血清中丙氨酸氨基转移酶与高密度脂蛋白胆固醇(ALT/HDL-C)的比例与糖尿病风险之间存在相关性。然而,目前尚无研究调查胰岛素抵抗(IR)与ALT/HDL-C之间的关联。因此,本研究旨在探讨美国成年人ALT/HDL-C与IR之间的关系。
    研究了2013年至2020年从国家健康与营养检查调查(NHANES)中选出的7,599名成年人。基于胰岛素抵抗的稳态模型评估(HOMA-IR)来评估IR。IR与ALT/HDL-C的关系通过多因素logistic回归分析,广义光滑曲线拟合和子群分析。
    多因素logistic回归分析显示IR与ALT/HDL-C有显著相关性,男性比值比(OR)为1.04(95%CI=1.02-1.05),女性为1.04(95%CI=1.02-1.07)。确定了ALT/HDL-C和IR风险之间的非线性关联和饱和效应,具有倒L形曲线和33.62处的拐点。ALT/HDL-C的ROC曲线下面积(AUC)明显较大(男性AUC=0.725,女性AUC=0.696,所有p<0.01)与使用ALT相比,HDL-C,AST和AST/ALT。亚组分析显示,肥胖个体和≥50岁个体的独立关联显著增高(所有P交互作用<0.05)。
    ALT/HDL-C升高与IR显著相关,可作为美国成年人IR的潜在指标。
    UNASSIGNED: Previous studies have demonstrated a correlation between the ratio of alanine aminotransferase to high-density lipoprotein cholesterol (ALT/HDL-C) in the serum and the risk of diabetes. However, no existing study has investigated the association between insulin resistance (IR) and ALT/HDL-C. Therefore, this study aims to explore the association between ALT/HDL-C and IR in American adults.
    UNASSIGNED: A total of 7,599 adults selected from the National Health and Nutrition Examination Survey (NHANES) in 2013 to 2020 were studied. IR was assessed based on the homeostatic model assessment of insulin resistance (HOMA-IR). And the association between IR and ALT/HDL-C was assessed through multiple logistic regression, generalized smooth curve fitting and subgroup analyses.
    UNASSIGNED: Multiple logistic regression analysis indicated a significant correlation between IR and ALT/HDL-C, with odds ratios (OR) of 1.04 (95% CI = 1.02-1.05) in males and 1.04 (95% CI = 1.02-1.07) in females. A non-linear association and saturation effect between ALT/HDL-C and IR risk were identified, with an inverted L shaped curve and an inflection point at 33.62. The area under the ROC curve (AUC) of ALT/HDL-C was significantly larger (AUC = 0.725 for males and 0.696 for females, all p < 0.01) compared with the use of ALT, HDL-C, AST and AST/ALT. Subgroup analysis showed a significantly higher independent association in obese individuals and individuals aged ≥50 years (All P interaction <0.05).
    UNASSIGNED: Elevated ALT/HDL-C demonstrates a significant correlation with IR, which can be used as a potential indicator of IR in American adults.

    目的:为了评估供体配子的利用率,患者满意度,和使用供体配子进行治疗的患者的生育治疗结果,根据配子供体的期望种族和种族进行分层。
    方法:调查研究对象:计划在2015年至2020年间在美国东南部的一家学术生育诊所使用供体精子和/或供体卵母细胞进行治疗的患者。
    无主要结果指标:供体配子的利用率,对供体配子选择和生育治疗结果的满意度按患者的种族和种族分层,以及他们的配子捐赠者。
    结果:四百五十名患者符合纳入条件,有170名(38%)对调查做出了回应。在受访者中,59%希望非西班牙裔白配子供体,20%希望非西班牙裔黑配子供体。与寻求非西班牙裔白人配子供体的个体相比,寻求非西班牙裔黑人配子供体的患者使用供体配子的几率较低(OR=0.13,95%CI0.04-0.40)。在评估对供体配子选择的满意度时,寻求非西班牙裔黑人配子供体的患者报告的满意度低于寻求非西班牙裔白人配子供体的患者(OR0.19,95%CI[0.09-0.43]).在评估生育结果时,与非西班牙裔白人患者(OR=0.18,95%CI0.07-0.46)和寻求非西班牙裔白人配子供体的个体相比,非西班牙裔黑人患者和使用非西班牙裔黑人配子供体的成功受孕几率较低。(OR=0.26,95%CI0.09-0.75),分别。
    结论:寻求非西班牙裔黑人供体配子的患者利用率较低,对配子供体选择的满意度较低,与寻求非西班牙裔白人配子捐赠者的人相比,受孕几率较低。这些发现强调了捐助者配子银行内部需要更多的种族多样性,以及通过机构和生育诊所提供的捐助者池中。
    OBJECTIVE: To evaluate donor gamete utilization, patient satisfaction, and fertility treatment outcomes of patients pursuing treatment with donor gametes stratified by the desired race and ethnicity of the gamete donor.
    METHODS: Survey study SUBJECTS: Patients planning to undergo treatment using donor sperm and/or donor oocytes at a single academic fertility clinic in the Southeastern United States between 2015 and 2020.
    UNASSIGNED: None MAIN OUTCOME MEASURES: Utilization rates of donor gametes, satisfaction with donor gamete selection and fertility treatment outcomes stratified by race and ethnicity of patient, as well as that of their gamete donor.
    RESULTS: Four hundred fifty patients were eligible for inclusion and 170 (38%) responded to the survey. Amongst the respondents, 59% desired a non-Hispanic White gamete donor and 20% desired a non-Hispanic Black gamete donor. Patients seeking a non-Hispanic Black gamete donor had lower odds of utilizing donor gametes (OR = 0.13, 95% CI 0.04 - 0.40) compared to individuals seeking a non-Hispanic White gamete donor. When evaluating satisfaction with donor gamete selection, patients seeking a non-Hispanic Black gamete donor reported lower satisfaction compared to individuals seeking a non-Hispanic White gamete donor (OR 0.19, 95% CI [0.09-0.43]). When evaluating fertility outcomes, Non-Hispanic Black patients and those utilizing non-Hispaninc Black gamete donors were found to have a lower odds of successful conception compared to non-Hispanic White patients (OR=0.18, 95% CI 0.07-0.46) and individuals seeking non-Hispanic White gamete donors (OR=0.26, 95% CI 0.09-0.75), respectively.
    CONCLUSIONS: Patients seeking non-Hispanic Black donor gametes have lower utilization rates, less satisfaction with gamete donor selection, and lower odds of conception when compared to those seeking non-Hispanic White gamete donors. These findings highlight the need for more racial diversity within donor gamete banks, as well as within the donor pools available through agencies and fertility clinics.

    确定静脉血栓栓塞(VTE)的危险因素有助于决定VTE的血栓预防。一项回顾性研究表明,在我们的人群中,高血压和糖尿病与VTE之间存在关联。这项研究的目的是确认这些发现,并确定完整的血细胞计数和凝血测试是否也可以作为对VTE患者进行分层预防的有用参数。
    这是一项性别和年龄匹配的前瞻性病例对照研究,研究对象为45例多普勒证实的DVT和43例明显健康的对照。
    确定的危险因素包括高血压病史,糖尿病,以前的DVT,最近的手术,最近的创伤,恶性肿瘤,脓毒症,和不动。这些病例的平均血细胞比容显着降低(33±7.4%vs38±4.6%,p<0.001)。尽管在病例和对照组之间没有观察到白细胞和血小板计数的差异,但两组之间的白细胞增多与白细胞减少(P=0.003)和血小板增多与血小板减少(P=0.045)分层存在差异。此外,病例中国际标准化比率(INR)较高(1.1±0.2vs1.0±0.1;P=0.001),分别在4.4%和28.9%的病例中观察到高凝状态(INR<0.9)和低凝状态(INR>1.2),而在对照组中没有观察到(P<0.001)。此外,aPTT>40秒分别见于4.4%和4.7%的病例和对照,aPTT<30秒见于22%的病例,但未见于对照(P=0.004)。
    高血压和糖尿病是传统上与DVT无关的危险因素。除了完整的血细胞计数和凝血测试之外,这些还可以用于对我们人群和其他类似社区中的患者进行分层以进行预防。
    UNASSIGNED: Identifying risk factors for venous thromboembolism (VTE) is useful in deciding thromboprophylaxis for VTE. A retrospective study had shown an association between hypertension and diabetes mellitus with VTE in our population. The objective of this study was to confirm these findings and to determine if the complete blood count and coagulation tests can also be useful parameters in stratifying VTE patients for prophylaxis.
    UNASSIGNED: This is a gender and age matched prospective case-control study of 45 Doppler\'s confirmed DVT and 43 apparently healthy controls.
    UNASSIGNED: Identified risk factors included history of hypertension, diabetes mellitus, previous DVT, recent surgery, recent trauma, malignancy, sepsis, and immobility. The cases had a significantly lower mean haematocrit (33±7.4% vs 38±4.6%, p<0.001). Though no differences were observed in leucocyte and platelet counts between cases and controls but stratification as leucocytosis vs leucopaenia (P=0.003) and thrombocytosis vs thrombocytopaenia (P=0.045) differed between both groups. Also, the International normalized ratio (INR) was higher in cases (1.1±0.2 vs 1.0±0.1;P=0.001), hypercoagulable state (INR<0.9) and hypocoagulable state (INR>1.2) were observed in 4.4% and 28.9% of cases respectively but not in controls (P <0.001). Also, aPTT>40 seconds was seen in 4.4% vs 4.7% of cases and controls respectively and aPTT< 30 seconds in 22% of cases but not in controls (P =0.004).
    UNASSIGNED: Hypertension and diabetes mellitus are identified risk factors not traditionally associated with DVT. These in addition to a complete blood count and coagulation tests can be useful in stratifying patients for prophylaxis in our population and other similar communities.

    先前的研究将中年时期的心血管危险因素与晚年的认知功能联系起来。然而,很少有研究研究心脏功能之间的关系,大脑结构,和认知功能,甚至更少包括不同的中年人群。
    本研究的目的是确定中年人的多种族队列中心脏和大脑结构与功能之间的关联。
    在达拉斯心脏研究2期的参与者中进行了一项横断面研究(N=1,919;46%的黑人参与者)。左心室(LV)质量,左心室射血分数,LV同心度,和峰值收缩期应变(LVEcc)通过心脏磁共振成像进行评估。通过液体衰减反转恢复磁共振成像测量白质高强度(WMH)体积。蒙特利尔认知评估用于测量认知功能。在调整心血管危险因素后,使用多变量线性回归确定心脏和大脑测量之间的关联,教育水平,和身体活动。
    左心室射血分数与蒙特利尔认知评估总分相关(β=0.06[95%CI:0.003-0.12],P=0.042)和LVEcc与WMH体积相关(β=0.08[95%CI:0.01-0.14],P=0.025)在整个队列中,种族/种族没有显着相互作用。较高的左心室质量和同心度与整个队列中较大的WMH体积相关(β=0.13[95%CI:0.03-0.23],P=0.008和0.10[95%CI:0.03-0.17],P=0.005)。这些关联在黑人中比白人参与者更占优势(β=0.17[95%CI:0.04-0.30]vsβ=-0.009[95%CI:-0.16至0.14],P=0.036和β=0.22[95%CI:0.13-0.32]vsβ=-0.11[95%CI:-0.21至-0.01],P<0.0001,对于LV质量和同心度,分别)。
    LVEF提示的亚临床心功能不全与认知功能降低相关。此外,左心室质量和同心重塑与较高的WMH负荷相关,尤其是黑人。
    UNASSIGNED: Previous studies have linked cardiovascular risk factors during midlife to cognitive function in later life. However, few studies have looked at the association between cardiac function, brain structure, and cognitive function and even less have included diverse middle-aged populations.
    UNASSIGNED: The objective of this study was to determine associations between cardiac and brain structure and function in a multiethnic cohort of middle-aged adults.
    UNASSIGNED: A cross-sectional study was conducted in participants of the Dallas Heart Study phase 2 (N = 1,919; 46% Black participants). Left ventricular (LV) mass, LV ejection fraction, LV concentricity, and peak systolic strain (LV Ecc) were assessed by cardiac magnetic resonance imaging. White matter hyperintensities (WMH) volume was measured by fluid attenuated inversion recovery magnetic resonance imaging. The Montreal Cognitive Assessment was used to measure cognitive functioning. Associations between cardiac and brain measures were determined using multivariable linear regression after adjusting for cardiovascular risk factors, education level, and physical activity.
    UNASSIGNED: LV ejection fraction was associated with total Montreal Cognitive Assessment score (β = 0.06 [95% CI: 0.003-0.12], P = 0.042) and LV Ecc was associated with WMH volume (β = 0.08 [95% CI: 0.01-0.14], P = 0.025) in the overall cohort without significant interaction by race/ethnicity. Higher LV mass and concentricity were associated with larger WMH volume in the overall cohort (β = 0.13 [95% CI: 0.03-0.23], P = 0.008 and 0.10 [95% CI: 0.03-0.17], P = 0.005). These associations were more predominant in Black than White participants (β = 0.17 [95% CI: 0.04-0.30] vs β = -0.009 [95% CI: -0.16 to 0.14], P = 0.036 and β = 0.22 [95% CI: 0.13-0.32] vs β = -0.11 [95% CI: -0.21 to -0.01], P < 0.0001, for LV mass and concentricity, respectively).
    UNASSIGNED: Subclinical cardiac dysfunction indicated by LVEF was associated with lower cognitive function. Moreover, LV mass and concentric remodeling were associated with higher WMH burden, particularly among Black individuals.

    背景:动脉僵硬度与年龄相关的认知功能障碍有关。估计的脉搏波速度(ePWV)与脑血管疾病有关。我们试图确定ePWV是否与多种族人群的认知相关。
    方法:我们纳入了1257名参加北曼哈顿研究磁共振成像MRI认知研究的参与者(平均年龄64±8岁,61%的女性,67%的西班牙裔,18%的非西班牙裔黑人,15%非西班牙裔白人),并分析了两个时间点的认知表现,在入学时和平均5.0±0.6年后。使用基线年龄和血压计算ePWV。在多变量线性回归模型中,认知和认知变化评分基于ePWV进行回归。
    结果:在调整后的模型中,ePWV(平均11±2m/s)与认知(b=-0.100,95%CI,-0.120,-0.080)和认知随时间的变化(b=-0.063,95%CI,-0.082,-0.045)显着相关。发现了种族和性别的效果变化。
    结论:在这个多民族人口中,ePWV与认知表现的相关性强调了血管僵硬在年龄相关性认知衰退中的作用.
    结论:ePWV是老年人认知功能和认知功能下降的适度但独立的预测因子。调整后,ePWV测量与全球认知的表现和下降呈负相关,处理速度,情景记忆,执行功能,和语义记忆。调整后,一个重要的相互作用术语表明,ePWV与情景记忆和执行功能的变化之间的关联因种族和种族而异。在女性中,ePWV与情景记忆下降之间的关联更强。
    BACKGROUND: Arterial stiffness is linked to age-related cognitive dysfunction. Estimated pulse wave velocity (ePWV) is associated with cerebrovascular disease. We sought to determine whether ePWV was associated with cognition in a multiethnic population.
    METHODS: We included 1257 participants enrolled in a Northern Manhattan Study magnetic resonance imaging MRI-cognitive study (mean age 64 ± 8 years, 61% women, 67% Hispanic, 18% non-Hispanic Black, 15% non-Hispanic white) and analyzed cognitive performance at two time points, at enrollment and on an average 5.0 ± 0.6 years later. ePWV was calculated using baseline age and blood pressure. Cognition and cognitive change scores were regressed on ePWV in multivariable linear regression models.
    RESULTS: In adjusted models, ePWV (mean 11 ± 2 m/s) was significantly associated with cognition (b = -0.100, 95% CI, -0.120, -0.080) and cognitive change over time (b = -0.063, 95% CI, -0.082, -0.045). Effect modification by race and sex was found.
    CONCLUSIONS: In this multiethnic population, the associations of ePWV with cognitive performance underline the role of vascular stiffness in age-related cognitive decline.
    CONCLUSIONS: ePWV is a modest but independent predictor of cognitive function and cognitive decline among older individuals. After adjustment, the ePWV measure was inversely associated with performance and decline in global cognition, processing speed, episodic memory, executive function, and semantic memory. After adjustment, modification of the association between ePWV and change in episodic memory and executive function by race and ethnicity was suggested by a significant interaction term. The association between ePWV and episodic memory decline was stronger in females.

    背景:左心室(LV)结构和功能的年龄相关变化降低了射血分数保留(HFpEF)的心力衰竭发作的阈值。LV参数也随种族而变化;然而,在有或没有调整体重指数(BMI)的情况下,LV参数的年龄相关变化的种族差异,心率(HR),血压(BP)仍不清楚。方法和结果:我们对世界联盟超声心动图正常值研究协会进行了分分析,一项国际横断面研究,检查了15个国家的正常超声心动图值。二维超声心动图衍生参数的年龄相关变化,包括左心室大小,收缩功能,和质量,在健康的日本人(n=227)和健康的白人(n=98)和黑人(n=69)美国参与者之间进行了比较。在男人中,所有参数的年龄相关变化在种族间无显著差异.然而,与日本女性相比,美国白人女性的体表面积(BSA)指数的LV体积较小,收缩末期BSA指数左心室内部尺寸,BSA指数左心室每搏输出量,和左心室质量指数对BSA,随着年龄的增长,左心室射血分数更大,即使在调整了BMI之后,HR,BP。
    结论:左心室结构和功能的年龄相关变化,这对HFpEF的病理生理学很重要,可能因种族而异。因此,未来的研究需要检查每个种族中每个年龄组的超声心动图参考值.
    BACKGROUND: Age-related changes in left ventricular (LV) structure and function lower the threshold for the onset of heart failure with preserved ejection fraction (HFpEF). LV parameters change also with race; however, the racial differences in age-related changes in LV parameters with and without adjustment for body mass index (BMI), heart rate (HR), and blood pressure (BP) remain unclear.Methods and Results: We performed a subanalysis of the World Alliance Society of Echocardiography Normal Values Study, an international cross-sectional study that examined normal echocardiographic values in 15 countries. The age-related changes in 2-dimensional echocardiographic derived parameters including LV size, systolic function, and mass, were compared between healthy Japanese (n=227) and healthy White (n=98) and Black (n=69) American participants. In men, age-related changes in all parameters did not differ significantly among races. However, compared with Japanese women, White American women had a smaller body surface area (BSA)-indexed LV volume, BSA-indexed LV internal dimension at end-systole, BSA-indexed LV stroke volume, and LV mass index to BSA, and a larger LV ejection fraction with age, even after adjusting for BMI, HR, and BP.
    CONCLUSIONS: Age-related changes in LV structure and function, which are important for the pathophysiology of HFpEF, may differ by race. Therefore, future studies examining echocardiographic reference values for each age group in each race are needed.

    目标:先前的工作发现,在边缘化的种族和族裔群体中,类似精神病的经历(PLEs)得到了越来越多的认可。根据社会决定因素框架,边缘化群体暴露于社会环境风险因素的风险增加,包括系统性因素(例如,贫困和恶劣的住房条件),和社会压力源(例如,歧视)。我们研究了环境风险因素和压力在多大程度上解释了种族/族裔群体与PLE之间的关联。
    方法:分析包括11,876名9-10岁的青少年青少年大脑认知发育(ABCD)研究。中介模型评估了1年随访时的压力是否将基线环境风险与2年随访时的痛苦PLE间接相关。系列调解模型检查了环境风险和压力是否间接导致自我报告的痛苦的PLE中种族/族裔群体之间的差异。
    结果:通过主成分和中介分析,我们发现了环境风险之间联系的证据(例如,贫困和犯罪暴露)和令人痛苦的精神病样经历是由压力介导的。也有证据表明,黑人和西班牙裔群体中对令人痛苦的精神病样经历的更高认可是由更大的环境风险和更大的压力连续介导的。
    结论:分析提供的证据表明,边缘化种族和族裔认同与PLEs认可之间的关联部分反映了系统性社会环境因素的后遗症。研究结果表明,随着时间的推移,可能会干预环境风险因素,以减少累积压力。这反过来又可以缓冲PLE的发展。
    OBJECTIVE: Previous work has found increased endorsement of psychotic-like experiences (PLEs) among marginalized racial and ethnic groups. According to social determinants frameworks, marginalized groups are at increased risk for exposure to socio-environmental risk factors, including systemic factors (eg, poverty and poor housing conditions) and social stressors (eg, discrimination). We examine the extent to which environmental risk factors and stress account for associations between racial/ethnic groups with PLEs.
    METHODS: Analyses included 11,876 young adolescents 9 to 10 years of age from the Adolescent Brain Cognitive Development (ABCD) study. Mediation models assessed whether stress at 1-year follow-up indirectly linked baseline environmental risk to later distressing PLEs at 2-year follow-up. Serial mediation models examined whether environmental risk and stress indirectly accounted for variation among racial/ethnic groups in self-reported distressing PLEs.
    RESULTS: Through principal component and mediation analyses, we found evidence that the link between environmental risk (eg, poverty and exposure to crime) and distressing PLEs was mediated by stress. There was also evidence that higher endorsement of distressing PLEs within the Black and Hispanic groups was serially mediated by greater environmental risk and greater stress.
    CONCLUSIONS: The analyses provide evidence that the associations between marginalized racial and ethnic identities with the endorsement of PLEs partially reflects the sequelae of systemic socio-environmental factors. Findings suggest the potential for intervening upon environmental risk factors to target the reduction of cumulative stress over time, which may in turn buffer against the development of PLEs.
    UNASSIGNED: We worked to ensure sex and gender balance in the recruitment of human participants. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented sexual and/or gender groups in science. We actively worked to promote sex and gender balance in our author group. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We worked to ensure that the study questionnaires were prepared in an inclusive way.

    绝望理论,贝克的认知理论,反应风格理论主导着我们对青少年抑郁症的理解和治疗。然而,支持他们的研究主要基于白人个体。Further,压力源之间的关联,认知脆弱性,根据这些理论的预测,黑人青少年的抑郁症状并不像人们所期望的那样。两者都提出了一个问题,即这些理论和先前的发现是否以及在多大程度上可以推广到黑人青少年。此外,没有理论基础,临床医生经常使用基于一种理论开发的干预措施来影响另一种理论中描述的漏洞.因此,我们研究的目的是研究综合认知压力脆弱性模型的结构以及压力源之间关联的优势,认知脆弱性,黑人和白人青少年的抑郁症状。在我们的研究中,来自公立高中的295名黑人(37%为女性)和213名白人(49%为女性)九年级学生参加了会议。网络分析表明,抑郁症的三种原始认知理论可以而且应该整合,我们检查的每个变量与黑人和白人青少年相当相关。同时,这两个综合网络的结构在黑人和白人青少年中差异显著,在四个边缘水平上表现出特定的区别。此外,黑人青少年的网络可预测性明显低于白人青少年。可以得出重要的理论和临床意义。
    The hopelessness theory, Beck\'s cognitive theory, and the response styles theory dominate our understanding and the treatment of depression in adolescents. However, research supporting them is largely based on White individuals. Further, the associations between stressors, cognitive vulnerabilities, and depressive symptoms in Black adolescents are not as one would expect based on the predictions from those theories. Both raise the question of if and to what degree these theories and previous findings can be generalized to Black adolescents. Additionally, without a theoretical basis, clinicians regularly use interventions developed based on one theory to influence vulnerabilities described in another theory. Thus, the purpose of our study was to examine the structure of an integrated cognitive stress-vulnerability model as well as the strengths of associations between stressors, cognitive vulnerabilities, and depressive symptoms in Black and White adolescents. In our study, 295 Black (37% female) and 213 White (49% female) ninth-grade students from a public high school participated. Network analyses demonstrated that the three original cognitive theories of depression can and should be integrated and that each variable we examined is comparably relevant for Black and White adolescents. At the same time, the structure of the two integrated networks differed significantly among Black and White adolescents, exhibiting specific distinctions at four edge levels. Furthermore, the predictability of the network is notably lower for Black adolescents than for White adolescents. Important theoretical and clinical implications can be derived.
