基于胸痛中心急救流程在急性心肌梗死患者救治中的应用

目的探讨基于胸痛中心急救流程在急性心肌梗死(AMI)患者救治中的应用效果。 方法选取镇江市急救中心2017年8月至2021年8月接诊的94例AMI患者为研究对象,其中男性50例,女性44例;年龄42~81岁,平均(60.37±4.31)岁。根据就诊顺序分为对照组和研究组,每组各47例,对照组患者接受常规急救流程,研究组患者接受基于胸痛中心基础上的急救流程,比较两组患者急救各环节时间、不良心血管事件发生率及患者满意度。 结果研究组患者急救各环节时间较对照组更短,两组比较差异有统计学意义(P<0.05);研究组患者不良心血管事件发生率显著低于对照组(6.38%比23.40%),两组比较差异有统计学意义(P<0.05);研究组患者满意度显著高于对照组(93.62%比78.72%),两组比较差异有统计学意义(P<0.05)。 结论基于胸痛中心急救流程可有效缩短急救过程中各环节时间,最大限度降低不良心血管事件发生风险,患者满意度高,对提高AMI患者救治效果、改善预后具有积极意义。     

Arthrodesis of the first metatarsophalangeal joint: The “when and how”

Arthrodesis of the first metatarsophalangeal (MTP) joint has been established as the “gold standard” for the treatment of several first ray disorders, due to its perceived efficacy and the consistently reported good results in the literature. Arthrodesis is a commonly performed procedure for the treatment of end stage arthritis, rheumatoid arthritis with severe deformity, selected cases of severe hallux valgus (with or without signs of degenerative joint disease), as well as a salvage procedure after failed previous operation of the first ray. The goals of a successful 1^st MTP arthrodesis are pain alleviation and deformity correction in order to restore a comfortable gait pattern and to improve shoe wear. Several techniques have been reported with several proposals regarding the preparation of the articular surfaces and the method of definitive fixation. As with any given surgical procedure, various complications may occur after arthrodesis of the 1^st MTP joint, namely delayed union, nonunion, malunion, irritating hardware, etc.      

The relationship between rates of hospitalization for ambulatory care sensitive conditions and local access to primary healthcare in Manitoba First Nations communities: Results from the Innovation in Community-based Primary Healthcare Supporting Transformation in the Health of First Nations in Manitoba (iPHIT) study

ObjectivesThe objective of this study was to assess the performance of models of primary healthcare (PHC) delivered in First Nation and adjacent communities in Manitoba, using hospitalization rates for ambulatory care sensitive conditions (ACSC) as the primary outcome.MethodsWe used generalized estimating equation logistic regression on administrative claims data for 63 First Nations communities from Manitoba (1986–2016) comprising 140,111 people, housed at the Manitoba Centre for Health Policy. We controlled for age, sex, and socio-economic status to describe the relationship between hospitalization rates for ACSC and models of PHC in First Nation communities.ResultsHospitalization rates for acute, chronic, vaccine-preventable, and mental health-related ACSCs have decreased over time in First Nation communities, yet remain significantly higher in First Nations and remote non-First Nations communities as compared with other Manitobans. When comparing different models of care, hospitalization rates were historically higher in communities served by health centres/offices, whether or not supplemented by itinerant medical services. These rates have significantly declined over the past two decades.ConclusionLocal access to a broader complement of PHC services is associated with lower rates of avoidable hospitalization in First Nation communities. The lack of these services in many First Nation communities demonstrates the failure of the current Canadian healthcare system to meet the need of First Nation peoples. Improving access to PHC in all 63 First Nation communities can be expected to result in a reduction in ACSC hospitalization rates and reduce healthcare cost.     

Adductor pollicis. The missing interosseous

Summary This paper highlights the many similarities between the adductor pollicis and the palmar interossei. In particular it compares their anatomy, innervation and function. It suggests that adductor pollicis should be considered as the first palmar interosseous and that this view simplifies the teaching of hand anatomy and the tests of ulnar nerve function. Further support for the view that adductor pollicis is the thenar counterpart of the second, third and fourth palmar interossei is gained from studies of the literature on hand evolution, in particular published details of fossil records and dissection of primate hands.

L'adducteur du pouce : l'interrosseux perdu

Résumé Cet article souligne les nombreuses similitudes qui existent entre le m. adducteur du pouce et le m. premier inter-osseux palmaire. Il compare en particulier l'anatomie l'innervation et la fonction de ces muscles. Le m. adducteur du pouce semble bien devoir être considéré comme le m. premier inter-osseux palmaire et ce point de vue simplifie l'enseignement de l'anatomie de la main ainsi que l'évaluation de la fonction du nerf ulnaire. Des arguments supplémentaires en faveur de l'hypothèse d'un m. adducteur du pouce qui serait la contre-partie thénarienne des second, troisème et quatrième mm. inter-osseux palmaires proviennent de l'étude de la littérature concernant la phylogénèse de la main et en particulier des résultats d'études portant sur les fossiles et les dissections de mains de primates.

     

RU486配伍米索前列醇中止瘢痕子宫早孕的安全性及可行性探讨

采用RU486配伍米索前列醇中止早孕188例,其中27例为瘢痕子宫。结果显示188例用药后完全流产率为91．48％;27例瘢痕子宫组为100％;161例非瘢痕子宫组为90．06％,两组完全流产率的差异无显著性意义,P>0．05,且两者绒球排出时间及出血时间亦无明显差异,瘢痕子宫组无一例严重并发症。提示RU486配伍米索前列醇口服中止瘢痕子宫早孕者安全、有效,并非其禁忌证,推荐为首选方法之一。     

Risk factors for mental disorder hospitalization after the Persian Gulf War: U.S. Armed Forces, June 1, 1991-September 30, 1993

Effects of Persian Gulf War (August 2, 1990–July 31, 1991) and Gulf War occupation on post-War hospitalization risk were evaluated through Cox proportional hazards modeling. Active-duty men (n = 1,775,236) and women (n = 209,760) in the Army, Air Force, Navy, and Marine Corps had 30,539 initial postwar hospitalizations for mental disorders between June 1, 1991 and September 30, 1993. Principal diagnoses in the Defense Manpower Data Center hospitalization database were grouped into 10 categories of ICD-9-CM codes. Gulf War service was associated with significantly greater risk for acute reactions to stress and lower risk for personality disorders and adjustment reactions among men. Personnel who served in ground war support occupations (men and women) were at greater risk for postwar drug-related disorders. Men who served in ground war combat occupations were at higher risk for alcohol-related disorders. Longitudinal studies of health, hospitalization, and exposure beginning at recruitment, are needed to better understand how exposure to combat affects the mental health of military personnel.
