老年腹股沟嵌顿疝全身麻醉腹腔镜手术对认知功能的影响

目的探讨腹腔镜微创手术对老年腹股沟嵌顿疝全麻术后认知功能的影响。 方法回顾性分析2015年3月至2018年6月，内江市第二人民医院接受治疗的44例腹股沟嵌顿疝老年患者临床资料，根据手术方式不同分为观察组（24例）和对照组（20例）。对照组采用开放式无张力疝修补术治疗，观察组采用腹腔镜经腹腹膜前疝修补术（TAPP）治疗。比较2组患者手术相关指标、手术前后焦虑、抑郁状态及认知功能及2组术后并发症发生情况。 结果与对照组比较，观察组术后排气时间、进食时间及自主下床活动时间均明显提前，差异有统计学意义（P<0.05）。与术前比较，术后2周2组患者焦虑自评量表、抑郁自评量表评分均明显降低，且观察组明显低于对照组，差异有统计学意义（P<0.05）。与术前比较，术后第2天2组患者即刻记忆力、回忆力、定向力、注意力及语言能力评分均明显降低，且观察组明显高于对照组，差异有统计学意义（P<0.05）。观察组总并发症发生率明显低于对照组，差异有统计学意义（P<0.05）。 结论TAPP配合围手术期精心护理可更有效地缓解腹股沟嵌顿疝老年患者不良心理情绪，对患者术后认知功能的影响更小，并发症少，有利于患者术后恢复，建议临床推广使用。     

Personality Changes With Dementia From the Informant Perspective: New Data and Meta-Analysis

Objective

To examine changes in personality in individuals with mild cognitive impairment (MCI) or dementia as observed by family members using both new data and a meta-analysis with the published literature.

Mindfulness and psychoeducation to manage stress in amnestic mild cognitive impairment: A pilot study

Objectives: Amnestic mild cognitive impairment (aMCI) often corresponds to the prodromal stage of Alzheimer disease (AD). The aMCI stage represents a crucial time window to apply preventive interventions in an attempt to delay cognitive decline. Stress, one of AD’s modifiable risk factors frequently co-occurring with aMCI, stands out as a key intervention target. The goal of this study was to assess the impacts of two non-pharmacological interventions, mindfulness and psychoeducation, on stress at the psychological and physiological levels among aMCI older adults.

Methods: Forty-eight aMCI participants were randomized between a mindfulness-based intervention (MBI) and a psychoeducation-based intervention (PBI) for eight weekly sessions. Anxiety symptoms, perceived stress levels, cortisol awakening response (CAR), and coping strategies were assessed pre- and post-intervention. Mindfulness attitudes and time dedicated to at-home meditative practices were evaluated in the MBI group.

Results: The main results revealed a slight reduction of the CAR among MBI participants who practiced meditation at home the most and a decrease in perceived stress levels in the PBI group. Both interventions enhanced problem-focused coping strategies.

Conclusion: In sum, this pilot study supports the potential of MBI and PBI to reduce stress at the physiological and psychological level, respectively, and increase coping strategies in older adults at risk for AD.     

Efficacy of the cognitive orientation to daily occupational performance with Brazilian children with developmental coordination disorder

Background: Children with Developmental Coordination Disorder (DCD) have difficulties performing daily activities which reflects negatively on participation, impacting their lives.

Objectives: To examine the effects of the cognitive orientation to daily occupational performance Approach (CO-OP Approach) protocol on occupational performance and satisfaction of Brazilian children who have DCD; to examine whether children could transfer strategies and skills learned during CO-OP to untrained goals.

Methods: A pre-post group comparison design with eight boys aged 6–10 years old. Children participated in 12 CO-OP sessions with their parents twice a week, with an extra session added to the protocol for parents´ orientation. The Canadian Occupational Performance Measure and the Performance Quality Rating Scale were used as outcome measures. The study was registered by the United States Institutes of Health at ClinicalTrials.gov (NCT03112746).

Results: Intervention resulted in higher, clinically and statistically significant, occupational performance measures according to parents, children’s, and external evaluators’ perspectives. All children improved occupational performance on their selected goals and five children could transfer the ability to use cognitive strategies to tasks not addressed in therapy.

Conclusions: This study provides initial directions for future research to investigate the applicability and to implement CO-OP approach on pediatric settings in Brazil.     

Tacrolimus overexposure in kidney transplant recipients during the first post‐operative week: caution is required in older patients

In liver transplantation, tacrolimus trough concentrations (Cmin) above 20 ng/mL during the first days led to worse outcome at 1 year but data in the kidney transplant (KT) era are scarce. The aim of this study was to evaluate the impact of tacrolimus overexposure during the first week post‐transplantation on the kidney function (KF) of KT recipients. In this retrospective study, 105 KT recipients were attributed to overexposure group (OG) or normal group according to their Cmin during the first week of treatment. KF was evaluated by comparing the rate of delayed graft function (DGF) and by collecting plasma creatinine from day 1, 2, 3, 4, 5, 6, 7, 14, 21, 28 and at 1 year. Risk factors for developing DGF were also investigated using a multivariate model. DGF was more frequent in OG (43% of patients; P = 0.027) which has higher plasma creatinine on day 7, 14, and 21. OG patients were older with more extended criteria donor's grafts. In the multivariate analysis, only cold ischemia time (CIT) remained associated with DGF (OR = 1.003), while TAC overexposure did not reach significance (P = 0.06; OR = 3.9). In this study, we confirmed the predominant role of CIT as a risk factor for the onset of DGF in kidney transplantation. 43% of KT recipients were overexposed with more DGF, especially older patients.     

瓦氏动作在脑血流自动调节功能中的应用

CA是指脑血流在动脉血压和脑灌注压发生改变时保持相对稳定的一个复杂的多因素过 程。脑血流自动调节与多种神经系统疾病如脑血管病、帕金森病、头痛、自主神经功能障碍等疾病的 发生、发展及临床预后相关。对脑血流自动调节功能有很多种评估测量方法，监测瓦氏动作所诱导 的血压变化更具有操作性及标准化，适用于各种人群，其安全、简单、准确的特点使其在脑血流自动 调节中运用十分广泛。本文重点对瓦氏动作在脑血流自动调节功能中的应用做一个综述介绍。
