  • 文章类型: Journal Article
    背景:低温被定义为身体核心温度低于35°C,并且可以由内部或外部压力引起。原发性体温过低是由于在没有任何医疗条件的情况下过度暴露于低环境温度引起的。继发性低温是由疾病引起的体温调节改变引起的,创伤,手术,毒品,或感染。研究的目的是研究在五个不同时间点接受特定水温的大鼠的核心温度值。它着重于区分这些大鼠的原发性和继发性低温。
    方法:将21只Wistar大鼠分为三个实验组:对照组大鼠仅暴露于低温条件(n=7);酒精低温(n=7);和苯并二氮卓类低温(n=7)。研究中分析的温度点是:正常核心温度,注射0.3氯胺酮期间的核心温度,浸泡温度和低温开始时的温度以及死亡时的温度。
    结果:在我们的研究中,对浸入水中后各个时间点的体温进行的比较分析显示,用酒精或苯二氮卓类药物治疗的研究组与对照组之间存在显着差异。在基线温度中观察到显著的差异,麻醉后诱导温度,和立即浸没后的温度。具体来说,发现酒精和苯并二氮卓组之间存在显着差异(p<0.001),酒精和对照组之间存在显着差异(p<0.001)。诱导低温后的生存时间分析显示,三个实验组之间存在统计学上的显着差异(p=0.04),尽管随后的事后比较未显示平均生存时间存在显著差异.
    结论:原发性和继发性低温组的生存时间存在差异,取决于酒精或苯二氮卓类药物的消费和中毒。诱导低温后的生存时间分析显示,两组之间存在统计学上的显着差异。
    BACKGROUND: Hypothermia is defined as a body core temperature below 35 °C and can be caused by internal or external stress. Primary hypothermia is caused by excessive exposure to low environmental temperature without any medical conditions prior to that. Secondary hypothermia is caused by alteration in thermoregulation by disease, trauma, surgery, drugs, or infections. The aim of the research is to investigate core temperature values in rats subjected to specific water temperatures at five different time points. It focuses on distinguishing between primary and secondary hypothermia in these rats.
    METHODS: The total 21 Wistar rats were divided into three experimental groups as: Control group rats exposed only to hypothermic condition (n = 7); Alcohol + hypothermia (n = 7); and Benzodiazepines + hypothermia (n = 7). The temperature spots analyzed in the study were: normal core temperature, core temperature during injection of 0,3 ketamine, temperature of immersion and the temperature at the onset of hypothermia and temperature at the time of death.
    RESULTS: In our study the comparative analysis of body temperatures at various time points following submersion in water revealed significant differences among the study groups treated with either alcohol or benzodiazepines and the control group. Notable differences were observed in baseline temperature, post-anesthesia induction temperature, and immediate post-submersion temperature. Specifically, significant differences were discovered among the alcohol and benzodiazepine groups (p < 0.001) and ranging from the alcohol and control groups (p < 0.001). The analysis of survival times following induced hypothermia revealed a statistically significant difference among the three experimental groups (p = 0.04), though subsequent post-hoc comparisons did not demonstrate significant differences in mean survival times.
    CONCLUSIONS: There is a difference in survival time between primary and secondary hypothermia groups, depending on consumption and intoxication with alcohol or benzodiazepines. The analysis of survival times following induced hypothermia showed a statistically significant difference among the groups.

    保留颈部的无骨水泥短杆代表了高功能需求患者全髋关节置换术的有效治疗选择,但是关于在上一代短茎中使用模块化的研究很少。该研究的目的是评估特定植入物设计的中期生存率,该植入物设计结合了部分颈短髋茎和颈部模块化;评估功能状态是第二个终点。
    对75名年龄在35至80岁的患者进行了回顾性单中心队列研究。至少6年随访。排除患有神经系统/风湿性疾病和先前进行过髋关节手术的患者。所有患者均接受了全髋关节置换术,并使用了短的模块化保留颈部的无骨水泥髋关节干。临床结果,并发症,修订,和西安大略省和麦克马斯特大学骨关节炎指数,哈里斯髋关节得分,并评估了简短的12项健康调查(SF-12)问卷。将结果与从文献中提取的健康人群数据进行比较,按年龄分层。
    Kaplan-Meier分析显示,植入物的10年生存率为96.7%,加上1.3%的修订率。结果显示,与健康人群相比,Harris髋关节评分和身体SF-12显着降低,而心理SF-12更高。在基于颈部模块化比较组时,没有出现统计学上的显着差异。
    对于功能需求升高的患者,短的模块化颈部保留非骨水泥髋关节干成为合理的选择,确保良好的临床结果,同时保持骨完整性。在短茎中使用模块化颈部在中期没有显示任何机械问题。
    UNASSIGNED: The neck-preserving cementless short stem represents a valid therapeutic option for total hip replacement in high-functional-demand patients, but few studies are available about the use of modularity in the last-generation short stem. The aim of the study was to evaluate the mid-term survival of a specific implant design that combines partial collum short hip stem with neck modularity; assessing the functional status was the second endpoint.
    UNASSIGNED: A retrospective single-center cohort study was conducted on 75 patients aged 35 to 80 years, with a minimum 6-year follow-up. Patients with neurological/rheumatic pathologies and previous hip surgeries were excluded. All the patients underwent total hip replacement with a short modular neck-preserving cementless hip stem. Clinical outcomes, complications, revisions, and the Western Ontario and McMaster Universities Osteoarthritis Index, Harris hip score, and Short Form 12-Item Health Survey (SF-12) questionnaires were evaluated. The results were compared with healthy population\'s data extracted from the literature, stratified by age.
    UNASSIGNED: The Kaplan-Meier analysis revealed a 10-year implant survival rate of 96.7%, coupled with a revision rate of 1.3%. Results showed a Harris hip score and physical SF-12 significantly lower and a mental SF-12 higher when compared to healthy population. No statistically significant differences emerged when comparing groups based on neck modularity.
    UNASSIGNED: The short modular neck-preserving cementless hip stem emerged as a reasonable choice for patients with elevated functional demands, ensuring good clinical outcomes while preserving bone integrity. The use of a modular neck in short stems didn\'t show any mechanical problems in the mid-term.

    COVID-19大流行对公共卫生系统构成了挑战,因为所有的卫生设施和人力都被转移到提供与COVID-19相关的服务。这影响了常规保健服务的提供,包括孕产妇保健服务。来自农村和初级医疗机构的数据很少,因为早期的研究要么基于模型,要么来自三级护理中心。
    这项基于记录的研究是在哈里亚纳邦法里达巴德地区的12个分中心进行的。检索了2017-2020年4月1日至9月30日期间登记的孕妇数据。将2020年4月1日至2020年9月30日期间登记的妇女的孕产妇保健服务利用情况与前3年(2017-2019年)同期登记的妇女进行比较。
    孕产妇医疗保健服务的利用率显着下降。至少四次产前检查等服务从67.8%下降到48.3%(P<0.0001),至少100片(45.4-20.9%;P<0.001),和检查在每次访问(90.8-72.3%;P<0.001)。接受充分产前护理的孕妇比例从26.0%下降到10.7%(P<0.001)。私营医疗机构的分娩率(40.9-49.9%)和剖腹产率(21.6-27.3%;P=0.002)显着增加。
    COVID-19大流行对孕产妇保健服务的利用产生了不利影响。各级政府卫生机构和初级保健提供者之间的有效规划和协调,包括家庭医生,可以确保在未来类似的紧急情况下不间断地提供基本服务。
    UNASSIGNED: The COVID-19 pandemic posed a challenge for the public health system, as all the health facilities and manpower were diverted for the delivery of COVID-19-related services. This affected the provision of routine health services, including maternal healthcare services. There is a paucity of data from rural and primary healthcare settings, as the earlier studies were either modelling-based or from tertiary care centres.
    UNASSIGNED: This record-based study was conducted in 12 subcentres in the district Faridabad of Haryana. Data of pregnant women registered during 1 April to 30 September in the years 2017-2020 were retrieved. The utilization of maternal healthcare services among women registered during 1 April 2020 to 30 September 2020 was compared with those registered in the same period during the preceding 3 years (2017-2019).
    UNASSIGNED: There was a significant decline in utilization of maternal healthcare services. Services like minimum four antenatal visits declined from 67.8% to 48.3% (P < 0.0001), at least 100 iron-folic acid tablets (45.4-20.9%; P < 0.001), and examination at each visit (90.8-72.3%; P < 0.001). The proportion of pregnant women who received full antenatal care decreased from 26.0% to 10.7% (P < 0.001). There was a significant increase in delivery in private health facilities (40.9-49.9%) and delivery by caesarean section (21.6-27.3%; P = 0.002).
    UNASSIGNED: COVID-19 pandemic had an adverse effect on utilization of maternal healthcare services. Effective planning and coordination between different levels of government health facilities and primary care providers, including family physicians, can ensure uninterrupted provision of essential services during similar emergencies in future.

    背景:如果没有有效的干预,原发性高草酸尿症1型(PH1)引起草酸盐诱导的肾脏损害,导致终末期肾病和全身严重并发症。尽管PH1带来了影响生活质量的沉重负担,关于PH1患者和PH1患者护理经验的文献有限.这项研究旨在描述PH1的诊断过程,并描述患者和护理人员在整个疾病过程中自我报告的经历。
    方法:这是一项观察性研究,半结构化电话采访。使用持续的比较分析来评估主导趋势,以确定受访者对其经历的描述中的主题。年龄≥12岁的个人和6-17岁儿童的看护人具有遗传证实的PH1是合格的。需要知情同意/同意和阅读和说英语的能力。
    结果:访谈(16例患者,12名护理人员)报告了由于疾病意识低而导致的诊断旅程延长,在其他因素中。诊断后,PH1经常有症状,通常涉及肾结石相关症状,但也有可能出现在肾脏以外的症状。PH1最常导致青少年的担忧和社交障碍,成人身体功能受损,以及对护理人员的一系列影响。在晚期疾病中,透析是PH1生活中最繁重的方面(由于时间要求,用导管生活的限制,等。),COVID-19大流行加剧了这一负担。希望从PH1管理的好处包括减少草酸盐负担的实验室措施,肾结石和排尿频率,和草酸盐相关的皮肤溃疡.
    结论:PH1极大地影响了患者和护理人员的生活,主要是由于繁重的疾病表现和相关的情绪,物理,和实际影响,以及疾病管理挑战-特别是与晚期疾病透析相关的挑战。
    Without effective intervention, primary hyperoxaluria type 1 (PH1) causes oxalate-induced kidney damage, leading to end-stage kidney disease and serious complications throughout the body. Although PH1 carries a heavy burden that impacts quality of life, literature on the experiences of those living with PH1 and caring for patients with PH1 is limited. This study aimed to describe the diagnostic journey in PH1 and characterize patients\' and caregivers\' self-reported experiences throughout the disease course.
    This was an observational study involving in-depth, semi-structured telephone interviews. Dominant trends were assessed using constant comparative analysis to identify themes in interviewees\' descriptions of their experiences. Individuals aged ≥ 12 years and caregivers of children aged 6-17 years with genetically confirmed PH1 were eligible. Informed consent/assent and ability to read and speak English were required.
    Interviewees (16 patients, 12 caregivers) reported a prolonged diagnostic journey due to low disease awareness, among other factors. Upon diagnosis, PH1 was frequently symptomatic, typically involving kidney stone-related symptoms but also potentially symptoms arising beyond the kidneys. PH1 most commonly led to worry and social impairment in adolescents, impaired physical function in adults, and a range of impacts on caregivers. In late-stage disease, dialysis was the most burdensome aspect of living with PH1 (due to time requirements, limitations from living with a catheter, etc.), and this burden was exacerbated by the COVID-19 pandemic. Benefits desired from PH1 management included reductions in laboratory measures of oxalate burden, kidney stone and urination frequency, and oxalate-related skin ulcers.
    PH1 greatly impacts patients\' and caregivers\' lives, primarily due to burdensome disease manifestations and associated emotional, physical, and practical impacts, as well as disease management challenges - particularly those related to dialysis in late-stage disease.

  • 文章类型: Clinical Trial, Phase I
    背景:四种共同循环和免疫相互作用的登革热病毒血清型(DENV1-4)对疫苗设计提出了独特的挑战,因为亚保护性免疫会增加严重登革热疾病的风险。现有的登革热疫苗在DENV血清阴性个体中具有较低的效力,但在暴露于DENV的个体中具有较高的效力。迫切需要鉴定在连续暴露于不同血清型后与针对病毒复制和疾病的保护密切相关的免疫学措施。
    方法:这是一项1期试验,其中健康成年人中和抗体为零(血清阴性),一个非DENV3(异型),或多于一种(多型)DENV血清型将用活的减毒DENV3单价疫苗rDEN3Δ30/31-7164接种。我们将研究疫苗前宿主免疫如何影响非地方性人群中DENV3疫苗接种的安全性和免疫原性。我们假设疫苗是安全的,耐受性良好,并且所有组的DENV1-4中和抗体几何平均滴度在第0天和第28天之间将具有显著增加。与血清阴性组相比,多型群会有较低的平均峰值疫苗病毒血症,由于先前的DENV暴露所提供的保护,而异型组会有更高的平均病毒血症峰,由于轻度增强。次要和探索性终点包括血清学特征,与生俱来的,和适应性细胞反应;评估DENV感染细胞的前病毒或抗病毒贡献;和免疫分析转录组,表面蛋白,和B和T细胞受体序列以及通过连续图像引导的细针穿刺采样的外周血和引流淋巴结中单细胞的亲和力。
    结论:本试验将比较初治后的免疫反应,次要,以及生活在非流行地区的自然感染人类的三级DENV暴露。通过评估新人群中的登革热疫苗并模拟交叉血清型免疫的诱导,这项工作可能为疫苗评估和扩大潜在目标人群提供信息.
    背景:NCT05691530于2023年1月20日注册。
    BACKGROUND: The four co-circulating and immunologically interactive dengue virus serotypes (DENV1-4) pose a unique challenge to vaccine design because sub-protective immunity can increase the risk of severe dengue disease. Existing dengue vaccines have lower efficacy in DENV seronegative individuals but higher efficacy in DENV exposed individuals. There is an urgent need to identify immunological measures that are strongly associated with protection against viral replication and disease following sequential exposure to distinct serotypes.
    METHODS: This is a phase 1 trial wherein healthy adults with neutralizing antibodies to zero (seronegative), one non-DENV3 (heterotypic), or more than one (polytypic) DENV serotype will be vaccinated with the live attenuated DENV3 monovalent vaccine rDEN3Δ30/31-7164. We will examine how pre-vaccine host immunity influences the safety and immunogenicity of DENV3 vaccination in a non-endemic population. We hypothesize that the vaccine will be safe and well tolerated, and all groups will have a significant increase in the DENV1-4 neutralizing antibody geometric mean titer between days 0 and 28. Compared to the seronegative group, the polytypic group will have lower mean peak vaccine viremia, due to protection conferred by prior DENV exposure, while the heterotypic group will have higher mean peak viremia, due to mild enhancement. Secondary and exploratory endpoints include characterizing serological, innate, and adaptive cell responses; evaluating proviral or antiviral contributions of DENV-infected cells; and immunologically profiling the transcriptome, surface proteins, and B and T cell receptor sequences and affinities of single cells in both peripheral blood and draining lymph nodes sampled via serial image-guided fine needle aspiration.
    CONCLUSIONS: This trial will compare the immune responses after primary, secondary, and tertiary DENV exposure in naturally infected humans living in non-endemic areas. By evaluating dengue vaccines in a new population and modeling the induction of cross-serotypic immunity, this work may inform vaccine evaluation and broaden potential target populations.
    BACKGROUND: NCT05691530 registered on January 20, 2023.

    背景:无水泥固定在原发性全膝关节置换术(TKAs)中越来越受欢迎。我们的随机临床试验(RCT)的前5年结果包括3种不同的胫骨设计,发现差异很小。本研究的目的是调查同一队列中的10年结果。
    方法:在2003年至2006年之间,对389个主要TKA进行了随机分配:传统模块化骨水泥胫骨(135);混合(骨水泥基板与非骨水泥钉)单体胫骨(128);和非骨水泥单体胫骨(126)。植入物幸存者,射线照片,并对临床结局进行分析。TKA的平均年龄为68岁(范围,41至85),46%为男性,平均BMI为32(范围,21至59)。平均随访时间为10年。
    结果:混合整体组和无水泥整体组的10年生存率相似,为96%,但较低(89%)的传统模块化骨水泥胫骨(p=0.05)。传统的模块化骨水泥胫骨组比其他2组对无菌性胫骨松动的修正明显更多(7vs.0%)在10年(p=0.003)。传统的模块化骨水泥胫骨组的非进行性射线可透线明显多于混合和非骨水泥单块组(24、12和9%,分别)。所有3组之间的临床结果相似且优异。
    结论:无骨水泥和混合整体胫骨组件具有出色的植入物存活率(96%),迄今为止没有无菌性胫骨松动病例。传统的骨水泥模块化胫骨组10年的无菌性松动累积发生率为7%。
    Cementless fixation is gaining popularity for primary total knee arthroplasties (TKAs). The prior 5-year results of our randomized clinical trial that included 3 different tibial designs found minimal differences. The purpose of the current study was to investigate the 10-year results in the same cohort.
    Between 2003 and 2006, 389 primary TKAs were randomized: traditional modular cemented tibia (135); hybrid (cemented baseplate with uncemented pegs) monoblock tibia (128); and cementless monoblock tibia (126). Implant survivorships, radiographs, and clinical outcomes were analyzed. Mean age at TKA was 68 years (range, 41 to 85), 46% were male, and mean body mass index was 32 (range, 21 to 59). The mean follow-up was 10 years.
    The 10-year survivorship free of any revision was similar between the hybrid monoblock and cementless monoblock groups at 96%, but lower (89%) for the traditional modular cemented tibia (P = .05). The traditional modular cemented tibia group had significantly more revisions for aseptic tibial loosening than the other 2 groups (7 versus 0%) at 10 years (P = .003). The traditional modular cemented tibia group had significantly more nonprogressive radiolucent lines than the hybrid and cementless monoblock groups (24, 12, and 9%, respectively). Clinical outcomes were similar and excellent between all 3 groups.
    Cementless and hybrid monoblock tibial components have excellent implant survivorship (96%) with no cases of aseptic tibial loosening to date. The traditional cemented modular tibial group had a 7% cumulative incidence of aseptic loosening at 10 years.

    未经证实:原发性肢体淋巴水肿的Stewart-Treves综合征(STS-PLE)是一种极为罕见的恶性肿瘤。进行了回顾性分析,以阐明磁共振成像(MRI)发现和体征与病理之间的关系。
    未经批准:在北京世纪坛医院招募了7名STS-PLE患者,首都医科大学,从2008年6月到2022年3月。所有病例均行MRI检查。对手术标本进行CD31、CD34、D2-40和Ki-67的组织病理学和免疫组织化学染色。
    未经证实:有两种不同类型的MRI表现。三名男性患者的一个是肿块状(STS-PLEI型),另一个是在四名女性患者中观察到的“垃圾桶”d标志(STS-PLEII型)。STS-PLEI型(18个月)的平均淋巴水肿(DL)持续时间短于STS-PLEII型(31个月)。STS-PLEI型的预后比STS-PLEII型的预后差。关于总生存期(OS),STS-PLEI型(17.3个月)比STS-PLEII型(54.5个月)短3倍。对于STS-PLEI型,STS-PLE发病年龄越大,OS越短。然而,STS-PLEII型无显著相关性。将MRI与组织学结果进行比较,以解释MR信号变化的差异,尤其是在T2WI上。在肿瘤细胞密集的背景下,未成熟血管和裂隙的管腔越丰富,T2WIMRI信号(以肌肉信号为内参标准)越高,预后越差,反之亦然。我们还发现,Ki-67指数较低(<16%)的年轻患者的OS较好,特别是STS-PLEI型。CD31或CD34阳性表达较强的患者OS较短。然而,D2-40的表达在几乎所有病例中都是阳性的,似乎与预后无关。
    未经证实:淋巴水肿,基于致密肿瘤细胞的未成熟血管和裂隙的管腔越丰富,MRI上的T2WI信号越高。在青少年患者中,肿瘤常出现"垃圾桶"征(STS-PLEII型),预后优于STS-PLEI型.而在中老年患者中,肿瘤呈肿块状(STS-PLEI型)。免疫组化指标CD31、CD34、KI-67的表达与临床预后相关,尤其是Ki-67表达降低。在这项研究中,我们确定将MRI结果与病理结果进行比较可以预测预后.
    UNASSIGNED: Stewart-Treves Syndrome in Primary Limb Lymphedema (STS-PLE) is an extremely rare malignant tumor. A retrospective analysis was conducted to elucidate the relationship between magnetic resonance imaging (MRI) findings and signs compared to pathology.
    UNASSIGNED: Seven patients with STS-PLE were enrolled at Beijing Shijitan Hospital, Capital Medical University, from June 2008 to March 2022. All cases were examined by MRI. The surgical specimens were subjected to histopathological and immunohistochemical staining for CD31, CD34, D2-40, and Ki-67.
    UNASSIGNED: There were two different types of MRI findings. One was mass shape (STS-PLE I type) in three male patients, and the other was the \"trash ice\" d sign (STS-PLE II type) observed in four female patients. The average duration of lymphedema (DL) of STS-PLE I type (18 months) was shorter than that of STS-PLE II type (31 months). The prognosis for the STS-PLE I type was worse than that for the STS-PLE II type. Regarding overall survival (OS), the STS-PLE I type (17.3 months) was three times shorter than that of the STS-PLE II type (54.5 months). For STS-PLE I type, the older the STS-PLE onset, the shorter the OS. However, there was no significant correlation in STS-PLE II type. MRI was compared to histological results to provide an explanation for the differences in MR signal changes, especially on T2WI. Against a background of dense tumor cells, the richer the lumen of immature vessels and clefts, the higher the T2WI MRI signal (taking muscle signal as the internal reference standard) and the worse the prognosis, and vice versa. We also found that younger patients with a lower Ki-67 index (<16%) had better OS, especially for the STS-PLE I type. Those with stronger positive expression of CD31 or CD34 had shorter OS. However, the expression of D2-40 was positive in nearly all cases, and seemed not to be associated with prognosis.
    UNASSIGNED: In lymphedema, the richer the lumen of immature vessels and clefts based on dense tumor cells, the higher the T2WI signal on the MRI. In adolescent patients, the tumor often showed a \"trash ice\" sign (STS-PLE II-type) and prognosis was better than for the STS-PLE I type. While in middle-aged and older patients, tumors showed a mass shape (STS-PLE I type). The expression of immunohistochemical indicators (CD31, CD34, and KI-67) correlated with clinical prognosis, especially decreased Ki-67 expression. In this study, we determined it was possible to predict prognosis comparing MRI findings with pathological results.

    未经评估:在我们的机构中,已在局麻下对肺部恶性肿瘤患者进行了CT引导经皮冷冻消融术.本研究旨在探讨经皮冷冻消融术治疗肺部恶性肿瘤的可行性和安全性。
    UNASSIGNED:从2002年7月至2016年12月,227例患者(56例原发性肺癌和171例转移性肺肿瘤)在我们机构的冷冻手术单元中接受了经皮冷冻消融术治疗恶性肺肿瘤。人口因素,治疗后住院的持续时间,在针对609个病灶的366个疗程中,对不良事件和死亡率进行了回顾性调查.
    UNASSIGNED:靶向肿瘤的中位直径为1.3cm。所有冷冻消融手术均在局部麻醉下完成,治疗后住院的中位持续时间为2天.在79个疗程中观察到不良事件(2级或更高)(21.6%),气胸是最常见的。在五次会议(1.4%)中,患者出现3级不良事件.没有30天的死亡率;然而,间质性肺炎急性加重导致2例60日死亡(0.5%).在多变量分析中,不良事件的独立预测因子为合并间质性肺炎[比值比(OR)=2.20;95%置信区间(CI):1.04~4.64]和治疗侧无肺切除术史(OR=3.04;95%CI:1.65~5.62).
    UNASSIGNED:冷冻消融术是一种可行且安全的恶性肺肿瘤治疗方法,不良事件发生率可接受。然而,应充分认识到合并间质性肺炎患者的死亡风险.
    UNASSIGNED: In our institution, computed tomography (CT)-guided percutaneous cryoablation has been performed in patients with malignant lung tumors under local anesthesia. This study aimed to examine the feasibility and safety of percutaneous cryoablation for the treatment of malignant lung tumors.
    UNASSIGNED: From July 2002 to December 2016, 227 patients (56 with primary lung cancer and 171 with metastatic lung tumor) underwent percutaneous cryoablation for the treatment of malignant lung tumors using a cryosurgical unit at our institution. Demographic factors, duration of post-treatment hospitalization, and adverse event and mortality rates were retrospectively investigated in 366 treatment sessions targeting 609 lesions.
    UNASSIGNED: The median diameter of the targeted tumor was 1.3 cm. All the cryoablation procedures were completed under local anesthesia, and the median duration of post-treatment hospitalization was two days. Adverse events (grade 2 or higher) were observed in 79 sessions (21.6%), with pneumothorax being the most common. In five sessions (1.4%), patients had grade 3 adverse events. There was no 30-day mortality; however, there were two 60-day mortality (0.5%) due to acute exacerbation of interstitial pneumonia. In multivariate analysis, independent predictors of adverse events were comorbid interstitial pneumonia [odds ratio (OR) =2.20; 95% confidence interval (CI): 1.04-4.64] and no history of pulmonary resection on the treated side (OR =3.04; 95% CI: 1.65-5.62).
    UNASSIGNED: Cryoablation is a feasible and safe treatment for malignant lung tumors with acceptable adverse event rates. However, the mortality risk in patients with comorbid interstitial pneumonia should be fully recognized.
