虚拟现实技术在儿童疼痛管理中的应用进展

近年来虚拟现实技术被引入医疗领域,成为疼痛管理的新形式,但目前在我国儿童疼痛管理中的应用较少。本研究从虚拟现实技术的概述、设备种类与使用方式、干预效果3个部分进行综述,以期为我国虚拟现实技术在儿童疼痛管理中的临床实践提供参考。     

The abscopal effect: a sense of DNA damage is in the air

Tumor metastasis is a singularly important determinant of survival in most cancers. Historically, radiation therapy (RT) directed at a primary tumor mass was associated infrequently with remission of metastasis outside the field of irradiation. This away-from-target or “abscopal effect” received fringe attention because of its rarity. With the advent of immunotherapy, there are now increasing reports of abscopal effects upon RT in combination with immune checkpoint inhibition. This sparked investigation into underlying mechanisms and clinical trials aimed at enhancement of this effect. While these studies clearly attribute the abscopal effect to an antitumor immune response, the initial molecular triggers for its onset and specificity remain enigmatic. Here, we propose that DNA damage–induced inflammation coupled with neoantigen generation is essential during this intriguing phenomenon of systemic tumor regression and discuss the implications of this model for treatment aimed at triggering the abscopal effect in metastatic cancer.     

Adherence to Chronic Kidney Disease Screening Guidelines Among Patients With Type 2 Diabetes in a US Administrative Claims Database

ObjectiveTo examine the screening rates for kidney damage and function among patients with type 2 diabetes (T2D) and chronic kidney disease stage at diabetes diagnosis using a US administrative claims database.Patients and MethodsThis cohort study used a claims database enriched with laboratory results data. Patients with T2D (defined as 1 inpatient or 2 outpatient claims for diabetes), aged 18 years or older, and with at least 1 year of follow-up enrollment were identified. Patients with type 1 diabetes, kidney disease, or other related conditions at baseline were excluded. We estimated screening rates using laboratory orders for serum creatinine and estimated glomerular filtration rate (eGFR) measurement and urine albumin to creatinine ratio (UACR). Chronic kidney disease severity was reported using the Kidney Disease: Improving Global Outcomes classification based on laboratory results.ResultsA total of 1,881,447 patients with T2D were eligible for analysis. Mean ± SD age was 63.1±13.1 years; 947,150 patients (50.3%) were male. Serum creatinine tests were ordered within 14 days of the index date among 290,722 patients of 622,915 (46.7%) patients with newly-recognized T2D. Overall, 1,595,964 patients (84.8%) had at least one serum creatinine test ordered during the 1-year follow-up period. Fewer patients received a UACR test during follow-up (814,897 [43.3%]). Less than half of all patients with T2D received a laboratory test order for both serum creatinine and urine albumin measurements during the follow-up period.ConclusionPhysicians treating patients with diabetes are selectively adhering to chronic kidney disease screening guidelines, as indicated by high rates of eGFR testing, but less frequent UACR testing. Despite recommendations to monitor both eGFR and UACR, less than half of patients were screened for albuminuria during the 1-year follow-up.     

The potential role of assisted oocyte activation in the management of a POSEIDON group 3 patient with fertilization failure: A case report and literature review

ObjectiveAssisted oocyte activation combined with ICSI (ICSI-AOA) has been reported to improve fertilization outcomes of couples with oocyte activation deficiency (OAD). Although there's no sufficient evidence to support ICSI-AOA as routine use, it might be beneficial for POSEIDON group 3 patients with suspected oocyte-related OAD.Case reportA 29-year-old female presented with a history of primary infertility for two years. She was classified as a POSEIDON group 3 patient and had a total fertilization failure history. With the help of ICSI-AOA, six oocytes were successfully fertilized. Pregnancy was later confirmed after embryo transfer. A living infant was born after 34 weeks of pregnancy.ConclusionOAD should be taken into consideration for POSEIDON group 3 patients since low Antimüllerian hormone is associated decreased quality. Further research needs to be done to understand the mechanism underlying oocyte-related OAD and the potential role of ICSI-AOA in young patients with suboptimal ovarian response.     

基于生物钟节律探讨前列腺癌的 发病机理及择时治疗策略

生物钟节律观与中医“天人一体”观相契合，生物钟节律紊乱可影响人体的生理病理状态，通过调节生物钟节律可达到提高治疗效果的目的。生物钟节律系统包括中枢生物钟节律系统与外周生物节律系统两大系统，分别在疾病发生发展中发挥不同的作用。与之相应，择时疗法是根据人体气血阴阳节律变化而选择相应药物治疗以达到最佳的疗效的一种时间医学治疗方法。临床上许多前列腺癌患者的发病与生物钟节律紊乱密切相关，通过调整生物钟节律具有预防和改善前列腺癌预后的积极作用。因此，本文将以现代生物钟节律的生理及病理机理为切入点，探讨不同生物钟节律系统紊乱在促前列腺癌中医主证形成过程中的发生机理，进而探讨择时治疗策略在不同类型前列腺癌治疗中运用的可行性，以期对前列腺癌的防治及预后产生一定的影响。
