目的 了解痛风患者痛风发作频率现状,分析其影响因素,为有针对性地预防和治疗痛风频发提供参考。方法 以2020年4月—2021年2月就诊于成都某风湿病专科医院的痛风患者为研究对象。收集研究对象的人口学特征、既往疾病史、行为生活方式、血生化指标,采用单因素分析、多分类logistic回归模型分析痛风患者发作频率的影响因素。检验水准α= 0.05。结果 498例痛风患者中,51（10.2%）例患者发作频率为1～2次/年,227（45.6%）例为3～4次/年,220（44.2%）例为5～26次/年。饮酒（χ2 = 7.011,P = 0.030）、蔬菜类（χ2 = 13.136,P = 0.001）、豆制品（χ2 = 5.986,P = 0.050）、牛奶/奶粉/羊奶（χ2 = 6.544,P = 0.038）、猪肥肉（χ2 = 7.957,P = 0.019）、是否规律作息（χ2 = 8.293,P = 0.014）在三组发作频率患者之间差异均有统计学意义。与发作频率为1～2次/年的患者相比,饮酒（OR = 1.95,95%CI:1.03～3.68）为发作频率3～4次/年患者的危险因素,每周2次豆制品摄入（OR = 2.96,95%CI:1.49～5.86）为发作频率5～26次/年患者的危险因素。结论 痛风患者大多一年发作3次以上,饮酒、食用豆制品是增加发作频率的危险因素,应针对这些危险因素,采取相应的预防措施。

内镜下结肠息肉高频电切除术后发生低血糖反应的相关因素及护理干预

目的探讨内镜下结肠息肉高频电切除术后发生低血糖反应的相关因素及护理干预措施。方法将2011年1-10月行内镜下结肠息肉高频电切除术的患者纳入研究,观察患者术后有无出现饥饿感、心慌、头晕、全身出冷汗、手抖、乏力等低血糖早期反应的症状,对出现低血糖反应者即刻测指尖血糖。结果共有142例患者入选,其中12例发生低血糖反应,患者既往有糖尿病病史、术前准备期间禁食过早、等待时间过长、术前补液不足、患者情绪紧张、术后静脉补液不当等是引致低血糖反应的主要相关因素。结论护理人员应加强患者病情评估、心理护理,重视术前准备时的健康宣教,合理安排检查治疗时间,密切注意病情观察,术后合理安排输液顺序,做好安全护理,尽量避免低血糖反应的发生。

Hypertension artérielle et risque cardiovasculaire associés au syndrome d’apnées obstructives du sommeil chez l’adulte en Guadeloupe

Background and purposeIn Guadeloupe, data on the relationships between arterial hypertension and obstructive sleep apnea are unavailable. The aim of this study was: to assess the frequency of hypertension and non-dipper pattern evaluated by 48-hour ambulatory blood pressure monitoring in an adult population identified obstructive sleep apnea/non-obstructive sleep apnea during overnight polygraphy ; to determine the cardio-metabolic factors associated with obstructive sleep apnea.Design and methodA cross-sectional study was realized at Pointe-à-Pitre Hospital. Patients were referred for suspected sleep apnea to sleep specialist and performed a nocturnal polygraphy. Diagnosis was confirmed if the apnea-hypopnea index was ≥ 5. We obtained two groups: sleep apnea/non-sleep apnea. All patients underwent 48-hour ambulatory blood pressure monitoring. The cardio-metabolic factors were identified and assessed (fasten level of hs-CRP and Homa-IR index).ResultsA total of 204 patients were included. Mean age at diagnosis was 54 ± 10 years, 63% were women. OSA was present in 69.6% with a higher frequency in men than in women. Difference was not significant between the two groups for hypertension frequency (84.5% vs 77%; P = 0.22), non-dipper pattern (77.5% vs 76%; P = 0.79) and hs-CRP. Differences for age, snoring, body max index, mean waist circumference, Homa-IR index, obesity, dyslipidemia, and type 2 diabetes were significant.ConclusionsOur data highlight raised frequency of cardiovascular metabolic factors in patients with obstructive sleep apnea and confirm their high cardiovascular risk.     

Frequency-specific Alterations of Large-scale Functional Brain Networks in Patients with Alzheimer's Disease

Background:

Previous studies have indicated that the cognitive deficits in patients with Alzheimer''s disease (AD) may be due to topological deteriorations of the brain network. However, whether the selection of a specific frequency band could impact the topological properties is still not clear. Our hypothesis is that the topological properties of AD patients are also frequency-specific.

Methods:

Resting state functional magnetic resonance imaging data from 10 right-handed moderate AD patients (mean age: 64.3 years; mean mini mental state examination [MMSE]: 18.0) and 10 age and gender-matched healthy controls (mean age: 63.6 years; mean MMSE: 28.2) were enrolled in this study. The global efficiency, the clustering coefficient (CC), the characteristic path length (CpL), and “small-world” property were calculated in a wide range of thresholds and averaged within each group, at three different frequency bands (0.01–0.06 Hz, 0.06–0.11 Hz, and 0.11–0.25 Hz).

Results:

At lower-frequency bands (0.01–0.06 Hz, 0.06–0.11 Hz), the global efficiency, the CC and the “small-world” properties of AD patients decreased compared to controls. While at higher-frequency bands (0.11–0.25 Hz), the CpL was much longer, and the “small-world” property was disrupted in AD, particularly at a higher threshold. The topological properties changed with different frequency bands, suggesting the existence of disrupted global and local functional organization associated with AD.

Conclusions:

This study demonstrates that the topological alterations of large-scale functional brain networks in AD patients are frequency dependent, thus providing fundamental support for optimal frequency selection in future related research.
