    目的:该研究旨在检查经常提到的第三磨牙是最常被拔牙的说法的真实性。这一发现以前没有在大量基于人群的样本中显示。
    方法:数据包括全国代表性样本的6082个全景射线照片取自2000年横断面健康调查的成年人。从射线照片上看,记录所有缺失的牙齿。从两个已发表的荟萃分析中检索了有关单个牙齿先天性发育不全的信息。主要结果是牙齿类型的牙齿缺失频率。解释变量是年龄,性别,和颌骨(上颌骨/下颌骨)。统计分析包括χ2检验和二项逻辑回归。
    结果:参与者的平均年龄(46%的男性,54%的女性)为53岁(SD14.6;范围30-97岁)。女性牙齿缺失发生率高于男性(P<0.001)。第三磨牙最常缺失,犬齿最不常见。在上颌骨和下颌骨,在80岁以下,第三磨牙的缺失频率高于其他牙齿类型(P<0.01)。
    结论:当考虑个别牙齿的先天性发育不全率时,结论是,直到80岁,第三磨牙仍然是最常见的牙齿。
    结论:第三磨牙是最常见的提取目标,但也是与医疗事故索赔相关的最常见的牙齿,因此,呼吁技能,充足的设备,和其他资源的成功提取。
    OBJECTIVE: The study aimed to examine the authenticity of the often-mentioned statement that the third molar is the most frequently extracted tooth. This finding has not been shown previously in a large population-based sample.
    METHODS: Data comprised a nationally representative sample of 6082 panoramic radiographs taken from adults in the cross-sectional Health 2000 Survey. From the radiographs, all missing teeth were recorded. Information on congenital agenesis of individual teeth was retrieved from two published meta-analyses. Primary outcome was the frequency of missing teeth by tooth type. Explanatory variables were age, sex, and the jaw (maxilla/mandible). Statistical analyses included χ2 test and binomial logistic regression.
    RESULTS: Mean age of participants (46% men, 54% women) was 53 years (SD 14.6; range 30‒97 years). Missing teeth occurred more often in women than in men (P < 0.001). The third molar was most frequently missing and the canine least frequently. In the maxilla and mandible, the third molar was missing more often than each of the other tooth types up to the age of 80 years (P < 0.01).
    CONCLUSIONS: When considering the rates of congenital agenesis of individual teeth, it is concluded that the third molar remained the most common tooth extracted up till the age of 80 years.
    CONCLUSIONS: The third molar is the most common target for extraction, but also the most common tooth associated with malpractice claims, and therefore, calls for skills, adequate equipment, and other resources for a successful extraction.

    本研究旨在分析trilaciclib的剂量-暴露-反应关系中潜在的种族差异,一类静脉内细胞周期蛋白依赖性激酶4/6抑制剂,用于治疗广泛期小细胞肺癌(ES-SCLC)患者化疗诱导的骨髓抑制.这项研究的重点是在中国和非中国患者中描述这些关系,以进一步完善中国ES-SCLC患者中trilaciclib的给药方案。人群药代动力学(PopPK)和暴露反应(E-R)分析使用来自四个随机2/3期试验的汇总数据进行,涉及中国和非中国ES-SCLC患者。PopPK分析显示,中国患者的trilaciclib清除率比非中国ES-SCLC患者高出约17%。性别和体表面积影响了这两个人群的trilaciclib药代动力学,但未产生明显的临床影响。E-R分析表明,随着剂量从200mg/m2增加到280mg/m2,trilaciclib暴露量增加,骨髓保护或抗肿瘤功效没有显着变化。然而,输液部位反应的发生率,头痛,在中国和非中国患有ES-SCLC的患者中,静脉炎/血栓性静脉炎随着三拉西尼暴露量的增加而增加。这些发现表明,中国和非中国患者之间的剂量-暴露-反应关系没有实质性的种族差异。他们支持在中国ES-SCLC患者中采用240-mg/m2静脉内3天或5天的三拉西尼给药方案。
    This study aimed to analyze potential ethnic disparities in the dose-exposure-response relationships of trilaciclib, a first-in-class intravenous cyclin-dependent kinase 4/6 inhibitor for treating chemotherapy-induced myelosuppression in patients with extensive-stage small cell lung cancer (ES-SCLC). This investigation focused on characterizing these relationships in both Chinese and non-Chinese patients to further refine the dosing regimen for trilaciclib in Chinese patients with ES-SCLC. Population pharmacokinetic (PopPK) and exposure-response (E-R) analyses were conducted using pooled data from four randomized phase 2/3 trials involving Chinese and non-Chinese patients with ES-SCLC. PopPK analysis revealed that trilaciclib clearance in Chinese patients was approximately 17% higher than that in non-Chinese patients with ES-SCLC. Sex and body surface area influenced trilaciclib pharmacokinetics in both populations but did not exert a significant clinical impact. E-R analysis demonstrated that trilaciclib exposure increased with a dosage escalation from 200 to 280 mg/m2, without notable changes in myeloprotective or antitumor efficacy. However, the incidence of infusion site reactions, headaches, and phlebitis/thrombophlebitis rose with increasing trilaciclib exposure in both Chinese and non-Chinese patients with ES-SCLC. These findings suggest no substantial ethnic disparities in the dose-exposure-response relationship between Chinese and non-Chinese patients. They support the adoption of a 240-mg/m2 intravenous 3-day or 5-day dosing regimen for trilaciclib in Chinese patients with ES-SCLC.

    OBJECTIVE: To present the baseline clinical and demographic characteristics of CRSwNP patients over the age of 18 enrolled in a Patient Support Program (PSP) prior to biologic treatment.
    METHODS: Descriptive, cross-sectional study performed in a Colombian CRSwNP asthma PSP sponsored by Sanofi from Aug-2021 to Jul-2022. Data was collected from CRSwNP patients, prior to the start of Dupilumab treatment, who consented to the use of their data. The following information was reported: Age, reporting city, treating medical specialty, comorbidities, and persistence of treatment.
    RESULTS: 339 patients were included, 171 (50,4%) were women and 168 (49,6%) were men. The mean age at Dupilumab treatment initiation was 52,4 years. 62,8% began treatment during adulthood (26-59y), while 34.1% started at elderly (+60y) and 3.1% were young adults (18-25y). Most cases (29,7%) were included in Bogotá, followed by Antioquia (19%), Valle del Cauca (7,3%) and the remaining 44% nationwide. Comorbidities were present in 67,1% of the patients, with diagnosis of allergic rhinitis, atopic dermatitis, asthma, and other non-type 2 inflammatory diseases. Nasal surgical history was present in 89,6% of the patients, most of them with one to three previous surgeries. Continuous treatment was observed in 70,3% of patients for 6 to 12 months, in 21,3% for more than 12 months and in 8,4% for less than six months. The most frequently treating medical specialty was otorhinolaryngology (79,6%), followed by allergology (16%) and other medical professionals (4,4%).
    CONCLUSIONS: There is concordance with the literature on a higher presentation of the disease in women than in men. There is a large proportion of patients with nasal surgical history and type 2 inflammatory comorbidities by the moment of biologic treatment initiation. The care and identification of CRSwNP colombian patients is mainly provided by otorhinolaryngologists, followed by allergologists.
    OBJECTIVE: Presentar las características clínicas y demográficas iniciales de los pacientes con RSCcPN, mayores de 18 años, inscritos en un Programa de Soporte al Paciente (PSP), antes del inicio de tratamiento biológico.

    以前的登记册显示,中东(ME)患有心血管疾病的平均年龄较年轻,但没有研究检查房室传导阻滞(AVB)。此外,这些比较与ME的年轻人群混淆.我们试图描述ME中AVB的平均年龄,并量化来自ME的影响,根据总体年轻人口进行了调整。
    这是对PANORAMA注册管理机构的回顾性分析,它收集了全球接受心律装置放置的患者的数据。人口年龄中位数≤30岁的国家被认为是“年轻国家”。进行多元线性回归以评估来自ME的影响,适应于来自一个“年轻的国家”,关于AVB演示的年龄。
    该研究包括5,259名AVB患者,640人(8.2%)来自ME。ME的平均年龄比其他地区年轻7岁(62.9±17.8与70±14.1,P<0.001)。来自“年轻国家”的人在演示时与5.6岁的年龄有关(95CI-6.5--4.6),而来自ME的患者在就诊时年龄较小3.1岁(95CI-4.5--1.8),(两者P<0.001)。
    在ME中出现AVB的平均年龄比其他地区小7岁。虽然这主要是由整体年轻人口驱动的,来自ME似乎与年轻年龄独立相关。需要评估ME早期陈述的决定因素,在应用国际建议时应该小心。
    Previous registries have shown a younger average age at presentation with cardiovascular diseases in the Middle East (ME), but no study has examined atrioventricular block (AVB). Moreover, these comparisons are confounded by younger populations in the ME. We sought to describe the average age at presentation with AVB in ME and quantify the effect of being from ME, adjusted for the overall younger population.
    This was a retrospective analysis of PANORAMA registries, which collected data on patients who underwent cardiac rhythm device placement worldwide. Countries with a median population age of ≤30 were considered \'young countries\'. Multivariate linear regression was performed to assess the effect of being from ME, adjusted for being from a \'young country\', on age at presentation with AVB.
    The study included 5,259 AVB patients, with 640 (8.2%) from the ME. Mean age at presentation was seven years younger in ME than in other regions (62.9 ± 17.8 vs. 70 ± 14.1, P < 0.001). Being from a \'young country\' was associated with 5.6 years younger age at presentation (95%CI -6.5--4.6), whereas being from ME was associated with 3.1 years younger age at presentation (95%CI -4.5--1.8), (P < 0.001 for both).
    The average age at presentation with AVB in the ME is seven years younger than in other regions. While this is mostly driven by the overall younger population, being from the ME appears to be independently associated with younger age. Determinants of the earlier presentation in ME need to be assessed, and care should be taken when applying international recommendations.

    背景:自我评估健康(SRH)提供了对老龄化人口不断发展的健康人口统计学的见解。
    目的:评估从老年到高龄的SRH的变化及其与健康和福祉因素的关系,并研究SRH与生存率之间的关系。
    方法:所有1940年前出生的MONICA1999复检参与者(n=1595)均纳入Silver-MONICA基线队列。2016年开始的Silver-MONICA随访包括80岁或以上的Silver-MONICA基线队列参与者。基线时,有1561名参与者的SRH数据可用,其中446名参与者也参与了随访。后续检查包括各种测量和测试。
    结果:大多数参与者在基线时将他们的健康状况评为“相当好”(54.5%)。在学习期间,42.6%有稳定的SRH,下降了40.6%,和16.8%有所改善。随访时SRH的变化与年龄显着相关,疼痛,营养,认知,助行器使用,自定步速的步态速度,下肢力量,日常生活活动的独立性,每周体育锻炼,户外活动,参加有组织的活动,拜访别人,士气,和抑郁症状。基线时的SRH与生存率显著相关(p<0.05)。
    结论:这项研究表明,SRH的变化与多种健康和福祉相关因素之间存在关联。以及生存和SRH之间的关系,强调它们在人口老龄化中的相关性。
    BACKGROUND: Self-rated health (SRH) offers insights into the evolving health demographics of an ageing population.
    OBJECTIVE: To assess change in SRH from old age to very old age and their associations with health and well-being factors, and to investigate the association between SRH and survival.
    METHODS: All participants in the MONICA 1999 re-examination born before 1940 (n = 1595) were included in the Silver-MONICA baseline cohort. The Silver-MONICA follow-up started in 2016 included participants in the Silver-MONICA baseline cohort aged 80 years or older. Data on SRH was available for 1561 participants at baseline with 446 of them also participating in the follow-up. The follow-up examination included a wide variety of measurements and tests.
    RESULTS: Most participants rated their health as \"Quite good\" (54.5 %) at baseline. Over the study period, 42.6 % had stable SRH, 40.6 % had declined, and 16.8 % had improved. Changes in SRH were at follow-up significantly associated with age, pain, nutrition, cognition, walking aid use, self-paced gait speed, lower extremity strength, independence in activities of daily living, weekly physical exercise, outdoor activity, participation in organized activities, visiting others, morale, and depressive symptoms. SRH at baseline was significantly associated with survival (p < 0.05).
    CONCLUSIONS: This study demonstrates associations between changes in SRH and a multitude of health- and wellbeing-related factors, as well as a relation between survival and SRH, accentuating their relevance within the ageing population.

    背景:关于大韩民国中风和急性心肌梗死(AMI)的流行病学信息有限。这项研究旨在开发一个国家监测系统,以使用国家索赔数据监测中风和AMI的发病率。
    方法:我们使用索赔数据开发并验证了中风和AMI的识别算法。该验证涉及2阶段分层抽样方法,并对抽样病例的病历进行审查。加权阳性预测值(PPV)和阴性预测值(NPV)是根据采样结构和相应的采样率计算的。通过将算法和加权PPV和NPV应用于2018年国民健康保险服务索赔数据,估计了大韩民国的中风和AMI的发病率。
    结果:总计,从2018年索赔数据库中抽取了2200例病例(1,086例中风病例和1,114例AMI病例)。算法对卒中的敏感性和特异性分别为94.3%和88.6%,对AMI的敏感性和特异性分别为97.9%和90.1%,分别。估计的病例数,包括复发事件,2018年中风为150,837例,AMI为40,529例。卒中和AMI的年龄和性别标准化发病率分别为180.2和46.1例/10万人年,分别,在2018年。
    结论:本研究证明了开发基于索赔数据和识别算法的国家监测系统以监测卒中和AMI发病率的可行性。
    BACKGROUND: Limited information is available concerning the epidemiology of stroke and acute myocardial infarction (AMI) in the Republic of Korea. This study aimed to develop a national surveillance system to monitor the incidence of stroke and AMI using national claims data.
    METHODS: We developed and validated identification algorithms for stroke and AMI using claims data. This validation involved a 2-stage stratified sampling method with a review of medical records for sampled cases. The weighted positive predictive value (PPV) and negative predictive value (NPV) were calculated based on the sampling structure and the corresponding sampling rates. Incident cases and the incidence rates of stroke and AMI in the Republic of Korea were estimated by applying the algorithms and weighted PPV and NPV to the 2018 National Health Insurance Service claims data.
    RESULTS: In total, 2,200 cases (1,086 stroke cases and 1,114 AMI cases) were sampled from the 2018 claims database. The sensitivity and specificity of the algorithms were 94.3% and 88.6% for stroke and 97.9% and 90.1% for AMI, respectively. The estimated number of cases, including recurrent events, was 150,837 for stroke and 40,529 for AMI in 2018. The age- and sex-standardized incidence rate for stroke and AMI was 180.2 and 46.1 cases per 100,000 person-years, respectively, in 2018.
    CONCLUSIONS: This study demonstrates the feasibility of developing a national surveillance system based on claims data and identification algorithms for stroke and AMI to monitor their incidence rates.

    背景:很少有基于人群的大型研究研究vonWillebrand病(PwvWD)患者的心理健康。
    目的:我们的目的是评估PwvWD患者在20年内抑郁和焦虑的患病率,并确定PwvWD患者更可能与抑郁和焦虑相关的出血症状。
    方法:这是一项回顾性队列研究,使用来自1,118家医院的非识别国家数据集,有1.76亿患者。病例被定义为患者,0-110年,男性和女性,vonWillebrand病(vWD),没有血友病。对照组定义为患者,0-110年,男性和女性,没有vWD或血友病。我们比较了病例和对照组的抑郁和焦虑发生率,以及出血症状的类型。
    结果:我们确定了66,367个PwvWD和183,890,766个对照。抑郁症的患病率(23.12%vs8.62%,P=<0.0001,RR=2.68)和焦虑(32.90%vs12.29%,P=<0.0001,RR=2.68)在PwvWD中更高。在PwvWD中,大多数出血症状与较高的抑郁和焦虑发生率相关,其中异常子宫出血的发生率最高。呕血,咯血,血尿,还有Melena.
    结论:我们的研究表明,PwvWD中的心理健康障碍是一个巨大的健康负担,随着出血症状的记录,这种负担会增加。重要的是,初级保健医生和血液学家照顾这个人群认识到这种增加的风险,并适当筛选和咨询心理健康专业人员。
    BACKGROUND: There are very few large population-based studies studying mental health in persons with von Willebrand disease (PwVWD).
    OBJECTIVE: We aim to assess prevalence of depression and anxiety in PwVWD over a period of 20 years and identify bleeding symptoms that may be more likely associated with depression and anxiety in PwVWD.
    METHODS: This is a retrospective cohort study using a deidentified national dataset from 1118 hospitals with 176 million patients. Cases were defined as patients aged 0-110 years, both male and female, with von Willebrand disease (VWD), without hemophilia. Controls were defined as patients aged 0-110 years, both male and female, without VWD or hemophilia. We compared rates of depression and anxiety in cases and controls and by type of bleeding symptoms.
    RESULTS: We identified 66 367 PwVWD and 183 890 766 controls. The prevalence of depression (23.12% vs 8.62%; p ≤ .00093; relative risk = 2.68) and anxiety (32.90% vs 12.29%; p ≤ .00093; relative risk = 2.68) was higher in PwVWD. Most of the bleeding symptoms were associated with higher rates of depression and anxiety in PwVWD with the highest rates with abnormal uterine bleeding, hematemesis, hemoptysis, hematuria, and melena.
    CONCLUSIONS: Our study shows that mental health disorders in PwVWD are a significant health burden, and that burden is increased with documented bleeding symptoms. It is important that primary care physicians and hematologists caring for this population recognize this increased risk and appropriately screen and refer to mental health professionals.

    目的:评估每日吸烟人群的社会人口统计学和健康相关特征,以前吸烟的人,以及在澳大利亚从不吸烟的人。
    方法:澳大利亚统计局(ABS)调查数据的横截面分析。
    方法:ABS2017-18国家健康调查(NHS)的成年参与者(16370名18岁或以上的人);ABS2018-19国家原住民和托雷斯海峡岛民健康调查(NATSIHS)的成年参与者(6423名18岁或以上的人)。
    方法:每天吸烟的人的社会人口统计学和健康相关特征,以前吸烟的人,和从不吸烟的人,以人口加权比例表示,总体上和自然性。
    结果:在成人NHS受访者中,估计有58.8%的人每天吸烟(95%置信区间[CI],56.2-61.4%)是男性,61.3%(95%CI,58.7-63.9%)为25-54岁,72.5%(95%CI,70.0-74.8%)出生在澳大利亚,65.4%(95%CI,62.8-67.8%)生活在主要城市,54.3%(95%CI,51.6-57.0%)生活在两个社会经济最不利的五分之一地区;75.9%(95%CI,73.5-78.1%)报告健康状况良好,73.0%(95%CI,70.5-75.4%)报告了低至中度的心理困扰,69.0%的25-64岁人群(即,工作年龄)已完成12年级(高中),目前有68.5%受雇。在澳大利亚,估计每天有257万人吸烟:237万非原住民(92%)和195,700原住民或托雷斯海峡岛民(8%)。
    结论:虽然生活在社会经济弱势地区和某些人口亚群体中吸烟更为频繁,这个第一个定量的国家概况表明,大多数每天吸烟的人都是有偿工作,是非土著的,身体和心理健康都很好,并完成了12年。改善以供应和需求为基础的全面结构性烟草控制,根据优先群体的需求和吸烟人群的整体状况,需要将成年人的每日吸烟率降低到2030年目标,即所有澳大利亚人的5%或更低,原住民和托雷斯海峡岛民的27%或更低。
    To assess the socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked in Australia.
    Cross-sectional analysis of Australian Bureau of Statistics (ABS) survey data.
    Adult participants (16 370 people aged 18 years or older) in the ABS 2017-18 National Health Survey (NHS); adult participants in the ABS 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) (6423 people aged 18 years or older).
    Socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked, expressed as population-weighted proportions, overall and by Indigeneity.
    Among adult NHS respondents, an estimated 58.8% of people who smoked daily (95% confidence interval [CI], 56.2-61.4%) were men, 61.3% (95% CI, 58.7-63.9%) were 25-54 years old, 72.5% (95% CI, 70.0-74.8%) were born in Australia, and 65.4% (95% CI, 62.8-67.8%) lived in major cities and 54.3% (95% CI, 51.6-57.0%) in areas in the two socio-economically most disadvantaged quintiles; 75.9% (95% CI, 73.5-78.1%) reported good to excellent health, 73.0% (95% CI, 70.5-75.4%) reported low to moderate psychological distress, 69.0% of those aged 25-64 years (ie, of working age) had completed year 12 (high school), and 68.5% were currently employed. An estimated 2.57 million people smoke daily in Australia: 2.37 million non-Indigenous people (92%) and 195 700 Aboriginal or Torres Strait Islander people (8%).
    While smoking is more frequent among people living in socio-economically disadvantaged areas and in certain population sub-groups, this first quantitative national profile indicates that most people who smoke daily are in paid employment, are non-Indigenous, are in good physical and mental health, and have completed year 12. Improved comprehensive structural supply- and demand-based tobacco control, informed by the needs of priority groups and the overall profile of people who smoke, is needed to reduce daily smoking prevalence among adults to the 2030 targets of 5% or less for all Australians and 27% or less for Aboriginal and Torres Strait Islander people.

    微塑料在水生环境中的普遍存在被认为是对水生生物的全球威胁。水蚤属的物种在水生初级生产者和较高营养水平的消费者之间提供了重要的联系;此外,这些生物对各种环境污染物表现出高度敏感性。因此,微塑料对水蚤物种的生物效应是有据可查的。本文综述了有关微塑料对水蚤的生态毒性作用的最新研究。包括:1)个人的反应,人口,和水蚤对微塑料的群落属性;2)微塑料的物理和化学性质的影响;3)微塑料和其他污染物对水蚤响应的联合毒性。我们的文献综述发现,已发表的文献没有提供足够的证据来揭示微塑料在人群和社区层面的风险。此外,我们强调,高层分析对于理解个体水平的研究如何揭示微塑料对水蚤的生态危害具有更普遍的意义.基于这篇综述,我们建议未来研究的途径,包括基于组学和社区层面方法的微塑料毒理学研究,尤其是后者。
    The ubiquitous presence of microplastics in aquatic environments is considered a global threat to aquatic organisms. Species of the genus Daphnia provide an important link between aquatic primary producers and consumers of higher trophic levels; furthermore, these organisms exhibit high sensitivity to various environmental pollutants. Hence, the biological effects of microplastics on Daphnia species are well documented. This paper reviews the latest research regarding the ecotoxicological effects of microplastics on Daphnia, including the: 1) responses of individual, population, and community attributes of Daphnia to microplastics; 2) influence of the physical and chemical properties of microplastics; and 3) joint toxicity of microplastics and other pollutants on responses of Daphnia. Our literature review found that the published literature does not provide sufficient evidence to reveal the risks of microplastics at the population and community levels. Furthermore, we emphasized that high-level analysis has more general implications for understanding how individual-level research can reveal the ecological hazards of microplastics on Daphnia. Based on this review, we suggest avenues for future research, including microplastic toxicology studies based on both omics-based and community-level methods, especially the latter.

    “四肢抢救”的努力,例如在感染从足部向近端扩散之前进行轻微截肢,以减少下肢严重截肢,是当今医疗保健的重要组成部分。目前尚不清楚这些努力是否阻止了大规模截肢的数量,并改善了患者的生活质量和美国医疗保健系统的成本效益。糖尿病患者的非创伤性下肢截肢(NLEA)比率在2000年代初有所下降,但在2010年代有所反弹。我们分析了德克萨斯州主要截肢的比例和不同年龄段截肢率的差异。患者数据从德州医院出院数据公共使用数据文件中提取。人口估计是从2011-2015年的德克萨斯州人口估计计划以及2006-2010年美国人口普查局提供的审查间估计中获得的。未成年人的原始数字,major,报告了每个年龄组的所有NLEA手术以及每年大截肢与总截肢的比率。进行泊松回归和Joinpoint分析以捕获这些趋势的变化。截肢率上升,主要截肢的相对患病率显着下降。45-64岁的糖尿病患者可能会导致这些增加。糖尿病患者下肢截肢的比率从2009-2015年增加。这适用于所有和轻微的截肢。相比之下,与2010年相比,大截肢与全部截肢的比率有所下降.大截肢和小截肢的使用在年龄组之间有所不同,在最年轻的科目中保持稳定,在45-64岁的人群中,轻微截肢率增加。临床证据水平:3级,预后。
    \"Limb salvage\" efforts, such as performing minor amputations before infections spread proximally from the foot to decrease major lower extremity amputation, are an important part of healthcare today. It is unclear whether these efforts are preventing the number of major amputations and improving patients\' quality of life and the cost-effectiveness of the U.S. healthcare system. Rates of non-traumatic lower extremity amputation (NLEA) among patients with diabetes decreased in the early 2000s but rebounded in the 2010s. We analyzed the proportion of major amputations and differences in amputation rates between age groups in Texas. Patient data was extracted from the Texas Hospital Discharge Data Public Use Data File. Population estimates were obtained from the Texas Population Estimates Program from 2011 to 2015 and from intercensal estimates provided by the U.S. Census Bureau from 2006 to 2010. Raw numbers of minor, major, and all NLEA surgeries and the ratio of major amputations to total amputations per year were reported for each age group. Poisson regression and Joinpoint analyses were performed to capture these changes in trends. Rates of amputations increased, with significant decreasing relative prevalence of major amputations. Patients aged 45 to 64 with diabetes are likely driving these increases. Rates of lower extremity amputation in patients with diabetes increased from 2009 to 2015. This holds for all and minor amputations. In contrast, the ratio of major to all amputations decreased from 2010. Utilization of major and minor amputation differs between age groups, remaining stable in the youngest subjects, with minor amputation rates increasing in those aged 45 to 64.
