多野照射、三维适形放疗与调强放疗对胃癌根治术患者癌周围组织的影响

目的:探讨多野照射、三维适形放疗与调强放疗对胃癌根治术患者癌周围组织的影响。方法:选取收治的103例行胃癌根治术的患者,将所有患者随机分为甲乙丙三组,其中甲组患者34例,均采用多野照射治疗;而乙组患者也是34例,均使用三维适形放疗;丙组患者则有35例,均使用调强放疗。观察比较各组患者放疗后的上腹部症状改善情况,并且检测各组患者的肝功能和血常规以及胰淀粉酶等临床指标,比较各组患者经治疗后的复发率以及生存率。结果:甲组患者的近期疗效显著低于乙组患者(P0.05),而乙组患者的近期疗效则明显低于丙组患者(P0.05);三组患者的钡餐造影均有所改善,但是其组间比较差异不具有统计学意义(÷2=9.012,P0.05)。甲组的不良反应率显著高于乙组和丙组(均P0.05),并且各组患者的不良反应中血常规异常的发生率显著高于肝功能和胰脏功能的异常(均P0.05),同时甲组患者出现放射性脊髓病的患者明显多于乙组(P0.05),仅丙组患者未见放射性脊髓病。随访三年间三组患者第一年随访生存率无明显差异(P0.05),而在第2年至第3年则三组患者的随访生存率有明显差异(均P0.05),其中随访生存率以丙组患者最高,其次为乙组患者;另外随访三年间甲组患者的随访复发率显著高于乙组和丙组患者(均P0.05),其复发率由低至高依次为丙组乙组甲组。结论:与多野照射治疗相比,三维适形放疗和调强放疗均能够更好地降低对胃癌周围组织的损伤和改善患者的临床症状,并且不良反应发生率低,对于降低复发率和提高生存率方面亦有不错的效果。     

红细胞分布宽度血小板比率和中性粒细胞淋巴细胞比率在急诊PCI术后冠脉无复流评估中的应用价值

目的:探讨红细胞分布宽度血小板比率(RDW)和中性粒细胞淋巴细胞比率(NLR)预测急诊经皮冠状动脉介入(PCI)术后冠脉无复流的应用价值。方法:选取2016年1月~2016年12月于我院行急诊PCI手术治疗的患者66例为研究对象,检测其治疗前的RDW和NLR,统计其急诊PCI术后冠脉无复流现象的发生情况,比较冠脉无复流和正常血流患者的RDW和NLR,分析患者RDW和NLR与其冠脉无复流的关系及其对冠脉无复流的预测价值。结果:66例患者急诊PCI术后冠脉无复流发生率为30.30%(20/66)。与正常血流患者比较,冠脉无复流患者RDW和NLR均升高(P0.05)。Spearman相关分析结果显示患者RDW和NLR与其冠脉无复流均呈正相关(r=0.826,0.878,P0.05)。进一步ROC曲线分析结果显示急诊PCI术前RDW和NLR联合预测其术后冠脉无复流的的ROC曲线下面积高于二者单独预测。结论:急诊PCI患者RDW和NLR与其术后冠脉无复流密切相关且两者联合预测患者术后冠脉无复流的价值良好,可能作为急诊PCI术后冠脉无复流评估的参考指标。

Atmospheric pressure fluctuations in the far infrasound range and emergency transport events coded as circulatory system diseases

This study examines whether a relation exists between rapid atmospheric pressure fluctuations, attributed to the far infrasound frequency range (APF), and a number of emergency transport events coded as circulatory system diseases (EEC). Over an entire year, the average integral amplitudes of APF in the range of periods from 3 s to 120 s over each hour (HA) were measured. Daily dynamics of HA averaged over the year revealed a wave shape with smooth increase from night to day followed by decrease from day to night. The total daily number of EEC within the city of Kiev, Ukraine, was related to the daily mean of HA (DHA) and to the ratio of HA averaged over the day time to HA averaged over the night time (Rdn), and was checked for confounding effects of classical meteorological variables through non-parametric regression algorithms. The number of EEC were significantly higher on days with high DHA (3.72-11.07 Pa, n = 87) compared to the low DHA (0.7-3.62 Pa, n = 260, p = 0.01), as well at days with low Rdn (0.21-1.64, n = 229) compared to the high Rdn (1.65-7.2, n = 118, p = 0.03). A difference between DHA and Rdn effects on the emergency events related to different categories of circulatory diseases points to a higher sensitivity of rheumatic and cerebro-vascular diseases to DHA, and ischaemic and hypertensive diseases to Rdn. Results suggest that APF could be considered as a meteorotropic factor capable of influencing circulatory system diseases.     

Ambient temperature and emergency room admissions for acute coronary syndrome in Taiwan

Acute coronary syndrome (ACS) is an important public health problem around the world. Since there is a considerable seasonal fluctuation in the incidence of ACS, climatic temperature may have an impact on the onset of this disease. The objective of this study was to assess the relationship between the average daily temperature, diurnal temperature range and emergency room (ER) admissions for ACS in an ER in Taichung City, Taiwan. A longitudinal study was conducted which assessed the correlation of the average daily temperature and the diurnal temperature range to ACS admissions to the ER of the city’s largest hospital. Daily ER admissions for ACS and ambient temperature were collected from 1 January 2000 to 31 March 2003. The Poisson regression model was used in the analysis after adjusting for the effects of holiday, season, and air pollutant concentrations. The results showed that there was a negative significant association between the average daily temperature and ER admissions for ACS. ACS admissions to the ER increased 30% to 70% when the average daily temperature was lower than 26.2°C. A positive association between the diurnal temperature range and ACS admissions was also noted. ACS admissions increased 15% when the diurnal temperature range was over 8.3°C. The data indicate that patients suffering from cardiovascular disease must be made aware of the increased risk posed by lower temperatures and larger changes in temperature. Hospitals and ERs should take into account the increased demand of specific facilities during colder weather and wider temperature variations.     

Diurnal temperature range and emergency room admissions for chronic obstructive pulmonary disease in Taiwan

The objective of this study was to assess the relationship between diurnal temperature range (DTR) and emergency room (ER) admissions for chronic obstructive pulmonary disease (COPD) in an ER in Taichung City, Taiwan. The design was a longitudinal study in which DTR was related to COPD admissions to the ER of the city’s largest hospital. Daily ER admissions for COPD and ambient temperature were collected from 1 January 2001 to 31 December 2002. There was a significant negative association between the average daily temperature and ER admissions for COPD (r =  −0.95). However, a significant positive association between DTR and COPD admissions was found (r = 0.90). Using the Poisson regression model after adjusting for the effects of air pollutants and the day of the week, COPD admissions to the ER increased by 14% when DTR was over 9.6°C. COPD patients must be made aware of the increased risk posed by large DTR. Hospitals and ERs should take into account the increased demand of specific facilities during periods of large temperature variations.

目的:探讨内支架对大肠癌急性梗阻一期切除吻合的疗效。方法:选择2010年7月至2012年7月来我院急诊治疗确诊为大肠癌导致急性肠梗阻的患者98例,随机分为观察组和对照组各49例,观察组患者植入内支架,一周后行一期吻合切除术,对照组行急诊切除手术。观察和比较两者患者一期切除率、治疗效果和并发症的情况。结果:观察组一期切除率为95.7%(47例)较对照组分71.4%(35例)高;两组比较差异均有统计学意义(x2=22.9,P0.05);实验组症状缓解48例(缓解率98%),对照组症状缓解33例(缓解率67.3%),两组临床疗效比较有显著性差异(x2=33.3,P0.001),实验组术后并发症发生率(10.2%)要明显小于对照组(26.5%)(x2=9.6,P0.01)。结论:大肠癌急性梗阻术前植入内支架能有效提高患者的一期手术吻合率和治疗效果,降低术后并发症,值得在临床推广。     

Frequent utilization of the emergency department for acute exacerbation of chronic obstructive pulmonary disease

Background

Little is known about patients who frequently visit the emergency department (ED) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We aimed to quantify the proportion and characteristics of patients with frequent ED visits for AECOPD and associated healthcare utilization.

Methods

We conducted a retrospective cohort study of adults aged ≥40 years with at least one ED visit for AECOPD between 2010 and 2011, derived from population-based all-payer data of State ED and Inpatient Databases for two large and diverse states: California and Florida. Outcome measures were frequency of ED visits for AECOPD, 30-day ED revisits, subsequent hospitalizations, near-fatal events (AECOPD involving mechanical ventilation), and charges for both ED and inpatient services (available only for Florida) during the year after the first ED visit.

Results

The analytic cohort comprised 98,280 unique patients with 154,736 ED visits for AECOPD. During the 1-year period, 29.4% (95% CI, 29.1%-29.7%) of the patients had two or more (frequent) visits, accounting for 55.2% (95% CI, 54.9%-55.4%) of all ED visits for AECOPD. In the multivariable model, significant predictors of frequent ED visits were age 55–74 years (vs. 40–54 years), male sex, non-Hispanic white or black race, Medicaid insurance (vs. private), and lower median household income (all P < 0.001). At the visit-level, 12.3% of ED visits for AECOPD were 30-day revisit events (95% CI, 12.1%-12.4%). Additionally, 62.8% of ED visits for AECOPD (95% CI, 62.6%-63.0%) resulted in a hospitalization; patients with frequent ED visits comprised 55.5% (95% CI, 55.2%-55.8%) of all hospitalizations. Furthermore, 7.3% (95% CI, 7.3%-7.5%) of ED visits for AECOPD led to a near-fatal event; patients with frequent ED visits accounted for 64.4% (95% CI, 63.5%-65.3%) of all near-fatal events. Total charges for AECOPD were $1.94 billion (95% CI, $1.90-1.97 billion) in Florida; patients with frequent ED visits accounted for $1.07 billion (95% CI, $1.04-1.09 billion).

Conclusions

In this large cohort study, we found that 29% had frequent ED visits for AECOPD and that lower socioeconomic status was significantly associated with a higher frequency of ED visits. Individuals with frequent ED visits for AECOPD accounted for a substantial amount of healthcare utilization and financial burden.
