慢阻肺急性加重期患者延迟就医与家庭动力学的相关性研究

目的研究慢阻肺急性加重期患者延迟就医与家庭动力学的相关性,希望能够为慢阻肺急性加重期患者拟定护理措施提供科学依据。方法选取2017年1月-2019年12月我院240例诊断为慢阻肺急性加重期的患者为研究对象。根据患者入院就医的时间进行分组,时间≥24h的延迟就医的患者为观察组,时间<24h的及时就医患者为对照组。结果两组患者在文化水平、家庭年收入、在职状态、医疗保险和婚姻状况和APACHEⅡ评分比较(P<0.05)。观察组患者疾病观念、个性化、系统逻辑和家庭氛围得分比对照组高(P<0.05)。Pearman的相关性分析结果显示:慢阻肺急性加重期患者延迟就医时间与各个层面分数以及家庭动力总分呈现负相关性(P<0.05)。应变量为延迟就医为应变量,患者的一般资料为自变量,经Logistic回归分析结果表明:延迟就医的影响因素为文化水平、家庭动力评分、职业状态、家庭收入、婚姻状况和APACHEⅡ评分。结论慢阻肺急性加重期患者家庭动力总分与疾病观念、个性化、系统逻辑和家庭氛围得分与延迟就医时间呈现负相关性,患者延迟就医的影响因素是家庭动力学评分。     

The danger of chlorhexidine in lignocaine gel: A case report of anaphylaxis during urinary catheterisation

This article describes a case of anaphylaxis secondary to chlorhexidine during urethral catheterisation. Despite little evidence for the use of antiseptic lubricants in preventing catheter-associated urinary tract infections, the distribution and use of such products continues to be widespread. Chlorhexidine-free lubricating gel is widely available and should be used for urological procedures wherever possible.     

Correlation between cow’s milk protein allergy and otitis media: a systematic review

ObjectivesTo review the evidence pertaining to the association between cow’s milk protein allergy and recurrent acute otitis media and otitis media with effusion.MethodsThe CENTRAL, Web of Science, EMBASE, MEDLINE, LILACS databases, and gray literature were searched.ResultsFour studies were included, identifying the prevalence rates: 0.2% of delayed speech due to chronic otitis media with effusion in 382 children with cow’s milk protein allergy, 10.7% of cow’s milk protein allergy in 242 children who underwent ENT procedures, 40% of cow’s milk protein allergy in 25 children with recurrent otitis media with effusion and higher tendency to otitis media in children with cow’s milk protein allergy of 186 children (1.5 + 0.6 vs. 0.4 + 0.1; p < 0.1).ConclusionConsidering the characteristics and methodological variations of the identified studies, it is not possible to state that there is reliable evidence of an association between cow’s milk protein allergy and otitis media.     

理气中药组方对糖尿病大鼠胃排空延迟的作用

目的:观察理气中药经验组方对糖尿病大鼠胃排空延迟的干预作用。方法:雌雄各半成年SD大鼠110只,随机分为正常组(A组)、糖尿病中药组(B组)、糖尿病胃复安组(C组)、糖尿病组(D组)。A组、D组1次/d按10 mL/只予0.9%生理盐水灌胃,B组1次/d按8 mL/只予中药煎剂灌胃,C组1次/d按0.5 mg/只予胃复安片灌胃。喂养12周后,行13C胃排空实验及甲基橙水溶液胃排空实验,观察各组大鼠胃排空情况。结果:糖尿病大鼠胃排空较正常大鼠明显延迟(P0.01),糖尿病大鼠胃排空延迟模型制作成功。糖尿病中药组和糖尿病胃复安组大鼠胃排空较糖尿病组快(P0.01);糖尿病中药组大鼠胃排空较糖尿病胃复安组大鼠快(P0.05)。结论:常规喂养12周后糖尿病大鼠出现胃排空延迟。理气中药陈皮、枳实、木香、香附组方煎剂和胃复安均能促进糖尿病大鼠胃排空,理气中药组方煎剂的效果优于胃复安。     

胰十二指肠切除术后胃排空障碍的诊疗进展

目的总结胰十二指肠切除术(PD)后胃排空障碍诊疗的现状与进展。方法检索近年来国内外有关PD后胃排空障碍的相关研究文献并进行综述。结果目前胃排空障碍的病因及发病机制尚未完全阐明,与手术创伤、患者高龄、合并糖尿病、伴有其他腹部并发症等多种高危因素有关。保留幽门PD并不增加术后胃排空障碍的风险,而幽门环切除、结肠前吻合、Braun吻合、微创手术对降低其发生是有利的。胃排空障碍的治疗目前国内外仍无明显进展,但绝大多数患者可通过对症保守治疗获得痊愈。结论 PD后胃排空障碍应以预防为主,围术期应用术后加速康复策略可能是目前临床解决术后胃排空障碍的关键所在,但需进一步研究。     

Topically injected adrenocorticotropic hormone induces mechanical hypersensitivity on a full‐thickness cutaneous wound model in rats

Cutaneous wound pain causes physical and psychological stress for patients with wounds. Previous studies reported that stress induces hyperalgesia and deteriorates wound healing. However, the effect of the stress response such as in hypothalamic‐pituitary‐adrenal (HPA) axis on local wound area is unclear. We aimed to investigate the effects of a stress response on the mechanical withdrawal threshold in the local wound area and describe the identification of a wound pain exacerbation. We topically injected adrenocorticotropic hormone (ACTH) into the granulation tissue of full‐thickness cutaneous wound model rats on the fifth day postwounding and measured the mechanical withdrawal thresholds, cytochrome P450 2Bs levels and concentration of 5,6‐epoxyeicosatrienoic acid in wound exudate. We found that ACTH induced mechanical hypersensitivity at 4 and 6 hours after injection (P = .004 and .021, respectively), and increased gene expression of cytochrome P450 2B12 expression (P = .046). Concentration of 5,6‐EET in the wound exudate was moderately correlated with the mechanical withdrawal threshold (r = ?.630). Finally, the mechanical withdrawal threshold in the 5,6‐EET group was significantly lower than that in the control group at 2 hours after the injection (P = .015). We propose that 5,6‐EET is one of the most promising contributors to the wound pain exacerbation. These findings could guide clinical wound and pain management.     

Utility of INR For Prediction of Delayed Intracranial Hemorrhage Among Warfarin Users with Head Injury

BackgroundIncidence of delayed intracranial hemorrhage (DICH) in patients on warfarin has been controversial. No previous literature has reported the utility of international normalized ratio (INR) in predicting traumatic DICH.ObjectivesUtilizing INR to risk stratify head trauma patients who may be managed without repeat imaging.MethodsThis was a retrospective study at a Level II trauma center. All patients on warfarin with head injuries from March 2014 to December 31, 2017 were included. Each patient underwent an initial head computed tomography scan (HCT) and subsequent repeat HCT 12 h after. Patients presenting > 12 h after head injury received only one HCT. Two blinded neuroradiologists reviewed each case of DICH. Statistical analysis evaluated Glasgow Coma Scale (GCS), Injury Severity Score (ISS), heart rate, systolic blood pressure (SBP), age, and platelet count.ResultsThere were 395 patients who qualified for the protocol; 238 were female. Average age was 79 years. Seventy-seven percent of patients underwent repeat HCT. Five resulted in DICH (INR 2.6–3.0), three of which might have been present on initial HCT; incidence rate of 0.51–1.27%. One patient required neurosurgical intervention. Among 80 patients with INR < 2, no DICH was identified, resulting in high sensitivity, but with a wide confidence interval; sensitivity of 100% (95% confidence interval [CI] 47.8–100), specificity 21% (95% CI 16.6–28.9). Correlation of factors: ISS (p = 0.039), GCS (p = 0.978), HR (p = 0.601), SBP (p = 0.198), age (p = 0.014), and platelets (p = 0.281).ConclusionNo patient with INR < 2 suffered DICH, suggesting that warfarin users presenting with INR < 2 may be managed without repeat HCT. For INR > 2, patients age and injury severity can be used for shared decision-making to discharge home with standard head injury precautions and no repeat HCT.
