观察评判性护理干预对乳腺癌手术后患者疼痛和睡眠质量的影响

目的:观察评判性护理干预对乳腺癌手术后患者疼痛和睡眠质量的影响。方法:选取2019年1月至2020年5月蚌埠医学院第一附属医院肿瘤内科收治的乳腺癌手术患者126例作为研究对象,按照随机数字表法分为观察组和对照组,每组63例。对照组给予常规护理干预,观察组给予评判性护理干预。采用抑郁自评量表(Self-rating Depression Scale,SDS)、焦虑自评量表(Self-rating Anxiety Scale,SAS)比较2组患者干预前后抑郁、焦虑状态改善情况,采用匹兹堡睡眠指数量表(Pittsburgh Sleep Quality Index,PSQI)比较2组患者睡眠质量变化,同时观察2组患者并发症发生率、中度、重度疼痛患者所占比例。结果:干预后,观察组SAS评分、SDS评分显著低于对照组,观察组PSQI评分显著低于对照组,患者中度、重度疼痛比例降低,并发症发生率降低,观察组的干预效果优于对照组,2组比较差异有统计学意义(P<0.05)。结论:对乳腺癌患者手术后采用评判性护理,可有效缓解患者手术后疼痛程度,改善患者睡眠质量,降低患者焦虑及抑郁情绪,降低并发症发生风险,值得推广使用。

Adherence to a Mediterranean Lifestyle and Changes in Frequency,Severity, and Localization of Pain in Older Adults

ObjectiveTo assess the association between adherence to a Mediterranean lifestyle and changes in pain, and its characteristics over time in older adults.Patients and MethodsWe analyzed data from 864 and 862 community-dwelling individuals aged 65+ years from the Study on Cardiovascular Health, Nutrition and Frailty in Older Adults in Spain (Seniors-ENRICA) Seniors-ENRICA-1 (2008–2010 to 2012) and Seniors-ENRICA-2 (2015–2017 to 2019) cohorts, with a median follow-up of 2.8 and 2.4 years, respectively. Adherence to a Mediterranean lifestyle was assessed at baseline with the 27-item Mediterranean lifestyle (MEDLIFE) index. Pain changes over time were calculated with a pain scale that assessed the frequency, severity, and the number of pain locations both at baseline and follow-up. Multivariable-adjusted relative risk ratios (RRRs) were obtained using multinomial logistic regression.ResultsIn the pooled cohorts, after a median follow-up of 2.6 years, pain worsened for 697 participants, improved for 734, and did not change for 295. Compared with the lowest category of MEDLIFE adherence, those in the highest category showed an RRR of improvement vs worsening of overall pain of 1.85 (95% CI, 1.28 to 2.67; P-trend<.001). MEDLIFE adherence was also linked to improvement in pain frequency (RRR, 1.98; 95% CI, 1.31 to 3.01; P-trend=.001), pain severity (RRR, 2.00; 95% CI, 1.33 to 3.00; P-trend=.001), and a reduction in the number of pain locations (RRR, 1.68; 95% CI, 1.13 to 2.50; P-trend=.004). Limitations of this study are the use of self-reported lifestyle data.ConclusionA Mediterranean lifestyle was associated with improvement of pain characteristics in older adults. Experimental studies should assess the efficacy of an integral lifestyle approach for the management of pain in older adults.     

Subtypes of insomnia and the risk of chronic spinal pain: the HUNT study

ObjectiveTo examine the association between subtypes of insomnia and the risk of chronic spinal pain.MethodsThe study comprised 16,401 participants without chronic spinal pain at baseline who were followed for ∼11 years. People were categorized into ‘no insomnia symptoms’, ‘subthreshold insomnia’, and ‘insomnia’. Insomnia was defined according to the diagnostic classification system requiring both daytime and nighttime symptoms, and further categorized into subtypes based on nighttime symptoms (ie, sleep onset latency [SOL-insomnia], wake after sleep onset [WASO-insomnia], early morning awakening [EMA-insomnia], or combinations of these). Subthreshold insomnia comprised those with only daytime impairment or one or more nighttime symptoms. Chronic spinal pain was defined as pain in either ‘neck’, ‘low back’, or ‘upper back’, or a combination of these.ResultsIn multivariable regression analysis using people without insomnia as reference, people with subthreshold insomnia or insomnia had relative risks (RRs) of chronic spinal pain of 1.29 (95% confidence interval [CI] 1.21–1.38) and 1.50 (95% CI 1.34–1.68), respectively. The RRs for people with one nighttime symptom were 1.30 (95% CI 0.83–2.05) for WASO-insomnia, 1.32 (95% CI 1.06–1.65) for EMA-insomnia, and 1.70 (95% CI 1.32–2.18) for SOL-insomnia, respectively. Combinations of nighttime insomnia symptoms gave RRs from 1.45 (95% CI 1.08–1.94) for WASO + EMA-insomnia to 1.72 (95% CI 1.36–2.19) for all nighttime symptoms (SOL + WASO + EMA-insomnia).ConclusionsThese findings suggest that the risk of chronic spinal pain is highest among persons with insomnia subtypes characterized by sleep onset latency or among those having insomnia symptoms in all parts of the sleep period.     

Changes in Health Literacy during the first year following a kidney transplantation: Using the Health Literacy Questionnaire

ObjectivesThe study aimed to identify changes in health literacy (HL) and associated variables during the first year following a kidney transplantation.MethodsA total of 196 transplant recipients were included in a prospective follow-up study. The patients answered the Health Literacy Questionnaire (HLQ) at 5 days, 8 weeks, 6 and 12 months following the kidney transplantation. Mixed linear models were used to analyze changes in HL and backward elimination was used to identify variables associated with HL.ResultsTwo main patterns of change were identified: a) HL increased during the first 8 weeks of close follow-up and b) in several domains, the positive increase from 5 days to 8 weeks flattened out from 5 days to 6 and 12 months. Self-efficacy, transplant-related knowledge, and general health were core variables associated with HL.ConclusionsOverall, HL increased during the 8 weeks of close follow-up following the kidney transplantation, while 6 months seem to be a more vulnerable phase. Furthermore, low self-efficacy, less knowledge, and low self-perceived health may represent vulnerable characteristics in patients.Practical implicationsFuture kidney transplant care should take into account patients’ access to and appraisal of health information and social support, and draw attention to potentially vulnerable groups.     

芫根调节免疫功能的小肠转录组学研究

利用生物信息学技术初步探索芫根调控肠道免疫功能的分子生物学机制。方法 选择雄性SPF级BALB/c小鼠18只，随机分为3组，每组6只。SC1组小鼠每只每次灌胃芫根提取液150 μL，SC2组小鼠每只每次灌胃绞碎芫根原浆悬液150 μL，NC组小鼠每只每次灌胃生理盐水150 μL，连续7 d每日灌胃一次。分别取每组小鼠小肠组织样品提取RNA，总RNA的质检合格后，进行转录组测序。按GO功能和KEGG信号通路对差异表达基因聚类分析揭示差异表达高度富集的免疫相关通路。从免疫角度分析芫根灌胃小鼠小肠组织的基因表达变化情况。结果 转录组测序共检测到27733条 mRNA的表达，SC1组与NC组比较，显著差异表达基因1635个，其中上调差异表达基因1236个，下调差异表达基因399个；SC2组与NC组比较，显著差异表达基因2872个，其中上调差异表达基因2233个，下调差异表达基因639个（P＜0.05）。按GO功能和KEGG信号通路聚类分析显示差异表达基因在白介素分泌、干扰素反应、T细胞受体信号通路及维生素和脂肪消化吸收等途径的富集度在两个芫根组中均居于前20位（P＜0.01），肠黏膜趋化因子CCL20和巨噬细胞极化标志物CD274等免疫蛋白编码基因差异表达显著且同属于上述多个免疫通路。结论 芫根灌胃小鼠小肠的差异表达基因在白介素分泌、干扰素反应、T细胞受体信号通路、营养物质消化吸收等途径高度富集，提示芫根对肠道免疫系统及肠黏膜功能的调节，其中CD274的表达上调和CCL20的表达下调提示诱导M1型巨噬细胞极化和T细胞活化可能是芫根调控免疫和维护肠道正常结构功能的重要途径。
