Effectiveness of Violet LED alone or in association with bleaching gel during dental photobleaching: A Systematic Review

AimsTo conduct a systematic review to determine the efficacy of violet led in promoting dental bleaching by itself or accelerating dental bleaching when associated with peroxides.MethodsClinical and in vitro studies were identified by a search on November 27th 2020 in the PubMed and Scopus databases. Inclusion criteria were: 1) studies related to bleaching; 2) studies related to violet LED Light (405-410nm); and 3) studies that analyzed efficacy. The authors assessed the studies for risk of bias independently. Authors extracted outcomes including color change evaluation and pain assessment independently.ResultsDuring the search process, 895 articles were found in the previously cited databases. After the first screening consisting of title and abstract evaluations, 18 articles were selected. Finally, 13 articles met the eligibility criteria and were included in this review, being 5 clinical trial/case series and 8 in vitro studies. In vitro studies showed a high risk of bias and interventional studies showed a low risk of bias.ConclusionThe violet Led seems to have the potential to bleach teeth without peroxides, with a clinical perceptible color alteration. However, the effect is small in comparison to bleaching using peroxides. When Violet Led is used in association with peroxides, it seems to potentialize the bleaching result. However, due to the high heterogeneity between studies, a small number of clinical studies, and the high risk of bias of the in vitro included studies, the results are not definitive, and further well-designed studies are needed to reach safe evidence.     

老年人群共病问题现状挑战与应对策略

中国已进入老龄化社会，共病是老年人群较为突出的公共健康问题。总结梳理老年人群共病领域研究现状，分析探讨相应策略对于老年共病人群的临床综合管理具有重要意义。本文重点从共病管理研究实践、共病诊疗模式、共病用药策略、共病医护团队及健康管理服务体系建设方面分析了该领域研究现状，同时提出建立以患者为中心的共病管理研究方案、推广应用老年共病评估工具、开展共病共有病因及机制研究、制订共病管理规范性指南/共识、借鉴中医学"以证统病""整体观念"思想、融合互联网+技术与智能可穿戴设备及开展共病早期风险评估与管理等应对策略，综合展望共病领域后期研究方向，以期为该领域进一步深入研究提供参考。     

亲密伴侣暴力评估工具的研究进展

亲密伴侣暴力（IPV）是指亲密伴侣之间发生的威胁或虐待行为，其具体形式包括身体、精神或性伤害。现有研究表明，IPV可给受害者带来一系列身体和心理上的损伤，严重影响受害者的生活质量。准确评估IPV是制定针对性预防措施的前提和基础。然而，国内对IPV的研究尚处于起步阶段，针对IPV的评估工具缺乏。本文将国外常用的8种IPV评估工具分为研究工具和筛查工具，对各工具的主要内容、应用情况及特点进行综述，并对这8种评估工具的优缺点进行比较，旨在为我国IPV相关研究提供借鉴，为准确评估和识别IPV受害者提供依据。     

Temporal changes in extra-axial brain hematoma's signal intensity in magnetic resonance images of trauma patients: A preliminary,technical study

IntroductionDating the exact or estimated time of trauma is an important issue facing forensic medicine. Several clinical and radiological methods were used to achieve this purpose. In the recent study, we aimed to track the changes in the signal intensity of the extra-axial brain hematoma using magnetic resonance imaging (MRI) conventional sequences as well as diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC).Materials and methodsConsidering inclusion and exclusion criteria, all patients with blunt head trauma were involved. After proper management., stabilization, and resuscitation, the participants were assessed using conventional sequences of MRI and DWI twenty-four hours, forty-eight hours, and three weeks after the injury. Temporal changes of signal intensity were compared by Wilcoxon ranged test.ResultsSixteen patients sustaining blunt head trauma were included in this study. The study showed that during the time, diffusion restriction could be seen in an extraaxial hematoma. At the first 24 hours, the signal of hematoma was void in 87.5% of DWI and 100% of ADC. On the second day, they were hypo-signal in 75% of DWI and 100% 0f ADCs, and after three weeks, 100% of cases were hyper-signal in DWI and hypo-signal ADCs.ConclusionThis preliminary study has shown that the DWI can be used to detect and track the extra-axial hematoma. The signal intensity was void during the first twentyfour hours, although it became hypo-signal after 48 hours. Of note, the diffusion restriction is noted after three weeks.     

Empowerment in people with Parkinson’s disease: A scoping review and qualitative interview study

ObjectiveTo synthesize empowerment definitions in Parkinson’s disease (PD) literature and understand people with PD’s perspective on empowerment in the context of an existing empowerment conceptual model.MethodsThis mixed-methods study included a scoping review of PD empowerment literature and interviews with adults with PD. Five databases were searched for articles that defined empowerment concepts. We analyzed 1:1 semi-structured interviews on empowerment with people with PD. All data were analyzed using hybrid thematic analysis.ResultsEight of 242 records were included in this review. Empowerment is defined as an intrapersonal (e.g., personal control over oneself or healthcare) or interpersonal construct (e.g., person-centered care). Thirty-seven participants completed the interview. Participants perceived empowerment as a multifaceted concept that interacts with determinants and moderators from different ecological levels.ConclusionEmpowerment is a noteworthy multilevel and relational construct that can interplay with important health-related factors. The developed working conceptual model of empowerment can inform future studies to explore empowerment concepts in more depth and develop PD empowerment-based interventions.Practice implicationsThe empowerment definitions, indicators, determinants, and moderators identified in this study can help researchers, clinicians, and policymakers critically conceptualize empowerment and develop interventions to support people with PD.
