Cribado de cáncer de pulmón: Supervivencia en un amplio programa de detección precoz en España (I-ELCAP)

IntroductionLung cancer (LC) is usually diagnosed at advanced stages with only a 12% 5-year survival. Trials as NLST and NELSON show a mortality decrease, which justifies implementation of lung cancer screening in risk population. Our objective was to show survival results of the largest LC screening program in Spain with low dosage computed tomography (LDCT).MethodsClinical records from International Early Lung Cancer Detection Program (IELCAP) at Valencia, Spain were analysed. This program recruited volunteers, ever-smokers aged 40-80 years, since 2008. Results are compared to those from other similar sizeable programs.ResultsA total of 8278 participants were screened with at least two-rounds until November 2020. A mean of 6 annual screening rounds were performed. We detected 239 tumours along 12-year follow-up. Adenocarcinoma was the most common histology, being 61.3% at stage I. The lung cancer prevalence and incidence proportion was 1.5% and 1.4%, respectively with an annual detection rate of 0.17. One-year survival and 10-year survival were 90% and 80.1%, respectively. Adherence was 96.84%.ConclusionLargest lung cancer screening in Spain shows that survival is improved when is performed in multidisciplinary team experienced in management of LC, and is comparable to similar screening programs.     

Silver Diamine Fluoride Protocol for Reducing Preventable Dental Hospitalisations in Victorian Children

IntroductionThis study was designed to assess whether a dental caries management protocol combining a single application of 38% silver diamine fluoride (SDF) with comprehensive oral health education will successfully divert high-risk children from dental treatment under dental general anaesthesia (DGA), arrest active caries in primary teeth, and improve parent-reported child oral health–related quality of life (OHRQoL).MethodsChildren aged 2 to 10 years, who attended two public dental agencies in Victoria, Australia, and were unable to tolerate restorative treatments in the clinic setting, elected to participate in either a 38% SDF intervention protocol or, alternatively, referral for DGA. Follow-up examinations were completed at 6 months to assess caries progression, decayed missing filled tooth index, PUFA index (pulpal involvement, ulceration, fistula, abscess), DGA referral rates, and OHRQoL (Early Childhood Oral Health Impact Scale [ECOHIS]).ResultsOf the total sample, 89.5% of children (n = 102) [mean (SD) age, 4.1 (1.0) years] with 401 active carious lesions elected to participate in the 38% SDF protocol; 10.5% (n = 12) of parents opted for referral for treatment under DGA. The proportion of active caries subsequently arrested at follow-up (number of arrested lesions/number of lesions treated) was 0.78 (95% CI, 0.69 to 0.87). There was an 88% reduction in referrals for DGA in eligible children over the 6-month period. The 38% SDF intervention group showed a significant improvement in ECOHIS scores at follow-up (P < .001).DiscussionAdoption of the 38% SDF intervention protocol resulted in a significant reduction in the rate of preventable dental hospitalisations. Most parents opted against referral for DGA. Parent-reported OHRQoL for children improved significantly.     

Outcomes of Prostatectomy versus Radiation Therapy in the Management of Clinically Localized Prostate Cancer Patients Within the PLCO Trial

Background

The objective of the study was to evaluate the outcomes of clinically localized prostate cancer treated with prostatectomy versus radiation therapy within the context of a prospective prostate cancer screening study.

妊娠早期阴道微环境变化及与阴道炎症的关系分析

目的分析妊娠早期阴道微环境变化及与阴道炎症的关系。方法回顾性分析2017年3月-2018年12月韶关市曲江区妇幼保健计划生育服务中心104例妊娠早期孕产妇临床资料。记录其非妊娠期及妊娠早期阴道微环境变化情况,包括酸碱度(pH)、菌群密集度、菌群多样性、阴道微生物功能正常率、乳杆菌阳性率、阴道微生态正常率,并比较妊娠早期阴道炎症发生情况及其阴道微环境。结果孕产妇非妊娠期pH、阴道微生物功能正常率、乳杆菌阳性率及阴道微生态正常率明显高于妊娠早期,菌群密集度、菌群多样性则低于妊娠早期,差异均有统计学意义(P<0.05)。孕产妇妊娠早期阴道炎症组pH、菌群密集度、菌群多样性明显高于无阴道炎症组,阴道微生物功能正常率及乳杆菌阳性率则低于无阴道炎症组,差异均有统计学意义(P<0.05)。结论妊娠早期阴道微环境出现一系列变化,造成阴道炎症发生率升高,对此临床应给予重视。     

某院注射剂避光药品管理的探索与实践

该文对某医院的注射剂避光药品管理进行研究,在该次研究中发现,某医院共有药品1 500多种,其中,避光注射剂的种类就达到了248种。由此可以看出,在医院的药品之中,避光注射剂的有着比较多的种类和数量。应该不断强化对注射剂避光药品的管理,这样才可以让这一类的注射剂发挥出其原有的作用,有效避免因避光不佳而导致的药物失效甚至一些临床不良反应的情况出现。     

Haemophilic Pseudotumour: Surgical Management of a Rare Case

Haemophilia is a common cause of genetically inherited bleeding disorders. Pseudotumours occur in 1–2 % of persons with severe forms of haemophilia. These are a result of repeated haemorrhage into soft tissues, subperiosteum or a site of bone fracture with inadequate resorption of the extravasated blood. There are a number of therapeutic alternatives for this dangerous condition: surgical removal, percutaneous management, irradiation, embolization etc. In this case report, we describe the natural history, clinical course and successful surgical management of a patient with haemophilia who presented with a massive pseudotumour. We also briefly review the relevant literature on the various therapeutic modalities that have been implemented in the management of this rare complication. Though surgeons may be averse to operate on haemophiliacs, primary surgical management as done in our case may prove to be the definitive treatment option for such patients.     

生命早期抗生素使用与儿童哮喘:因果关系还是混杂效应?

儿童哮喘的发病率逐年上升.基于卫生假说,抗生素使用可能减少了微生物暴露,从而增加了过敏性疾病发生的风险.近十年来,就早期抗生素暴露与儿童哮喘的关系进行的大量的流行病学调查的结果并不一致.大多数回顾性研究发现正相关联系,但前瞻性研究未发现联系或联系强度较弱.逆向因果和指示混淆可部分解释两者的关系,但也难以否定因果关系的存在.
