背景：有必要将肺癌筛查的资格标准扩大到年龄和吸烟史之外。在这项研究中，我们试图评估轻度或从不吸烟者和重度吸烟者在基于传统肺癌筛查标准的分子和免疫标志物上是否存在差异。方法：我们对加拿大一所高等教育机构2005年至2018年的肺癌病例进行了回顾性研究。我们使用多变量logistic回归比较轻度或从不吸烟者和重度吸烟者的分子突变率（KRAS、EGFR、BRAF、PIK3CA、ALK和PD-L1[< 1%, 1%-49%,≥50%]）和生存率。结果：我们纳入了1156例肺癌患者。总体而言，46.4% （National Lung Screening Trial [NLST], n = 536）和63.3% （Nederlands-Leuvens Long-kanker Screenings Onderzoek [NELSON], n = 732）的患者是重度吸烟者。使用NELSON标准，筛检不合格的轻度吸烟者或从不吸烟者（n = 175[41.3%]）比筛检合格的重度吸烟者（n = 285[38.9%]）更多地来自氡暴露高风险地区。轻度吸烟者或从不吸烟者在两种NLST中更有可能呈egfr阳性(优势比[OR] 0.79, 95%可信区间[CI] 0.21-1.37；p = 0.008]和NELSON (OR 0.79, 95% CI 0.28-1.31；P = 0.002)模型。在NELSON患者中，女性轻度吸烟或从不吸烟比男性轻度吸烟或从不吸烟更容易出现egfr阳性(OR 0.59, 95% CI 0.06-1.12；p = 0.03]但NLST除外(OR 0.51, 95% CI 0.02-1.05；P = 0.06)模型。NLST检测结果显示，轻度或从不吸烟的患者pik3ca呈阳性(OR 1.33, 95% CI 0.54-2.13；p = 0.001)和NELSON (OR 1.19, 95% CI 0.49-1.90；P = 0.001)模型。在NELSON模型中，不吸烟或不吸烟的人死亡风险更高。结论：当使用基于试验的肺癌筛查资格标准定义时，不符合筛查条件的轻度吸烟者或从不吸烟者的egfr和pik3ca阳性肺癌的发生率高于符合筛查条件的重度吸烟者。分子谱分析，特别是在有靶向治疗的情况下，应该在未来的研究中考虑建立肺癌筛查标准。背景：我不认为所有的数据都是不可接受的，所以我认为所有的数据都是不可接受的，所以我认为所有的数据都是不可接受的。如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外，如有例外。方法:我们就像一个revue回顾des cas de癌症du poumon 2005 2018在行动etablissement tertiaires法裔加拿大人。研究结果表明，两组患者的生存率均低于对照组（KRAS、EGFR、BRAF、PIK3CA、ALK和PD-L1[< 1%, 1% - 49%,≥50%]）。RÉSULTATS: Nous avons包括1156例癌症。总体而言，46.4%（全国肺部筛查试验]，n = 536）和63.3%（荷兰- leuvens Longkanker筛查Onderzoek]， n = 732）的研究表明，患有先天性肺部疾病的人患有先天性肺部疾病。À第1组，不可受理的au - sys (n = 175[41.3%])；第2组，不可受理的au - sys （n = 285[38.9%]）。1组患者合并易感患者être egfr阳性，1组患者NLST (rapport des cotes [RC] 0.79, confy [IC] 0.95, 0.21 - 1.37；p = 0,008), que le mod NELSON (RC 0,79, IC de 95% 0,28-1,31；P = 0.002)。1组，女性患者和易感人群分别为：男性患者和男性患者，分别为：être egfr阳性；p = 0,03)，主要非selonle模态NLST (RC = 0,51, IC = 95%, 0,02-1,05；P = 0,06)。Le 1组avwait + tenance être pik3ca阳性selon les modles NLST (RC 1,33, IC de 95% 0,54-2,13；p = 0.001)和NELSON (RC 1,19, IC = 95% 0,49-1,90；P = 0.001)。Selon le mod NELSON，第1组的samtaise暴露了unrisque de mortality it和samtaise。结论:Les人不le tabagisme est分类帐voire nul残余是不容许盟depistage游客现在联合国taux +与德癌症du poumon EGFRet PIK3CA-positifs comparativement辅助gros吸烟者,当我们appliquait Les准则d 'admissibilite盟depistage du癌症du poumon des 2 essais引用。如果有一种情况是，如果有一种情况是，如果有一种情况是，如果有一种情况是，如果有一种情况是，如果有一种情况是，如果有一种情况是，如果有一种情况是，那么就会有一种情况是，如果有一种情况是，那么就会有一种情况是，如果有一种情况是，那么就会有一种情况是，如果有一种情况是，那么就会有一种情况是，那就是：

背景：由于三级医疗中心通常位于城市，因此尚不清楚农村地区的患者是否能获得与城市地区患者相同的手术服务。我们试图绘制出北美乡村性如何影响获得医学指征手术的证据景观，并确定系统、患者和提供者层面的障碍，这些障碍阻碍了城市可比的护理。方法：我们按照PRISMA的Scoping Reviews方法对PubMed、MEDLINE、Scopus和Web of Science进行了系统检索，包括过去26年（2023年1月）的文献。搜索词包括“农村人口”、“医疗保健”、“外科手术”和“健康差距”。我们用叙述的方法综合了我们的发现。结果：在13897项确定的研究中，我们纳入了71篇出版物，涵盖了广泛的外科学科。其中，83%报告手术机会减少，17%报告手术机会加快，30%报告农村与其他健康社会决定因素之间的相互作用，特别是年龄、性别和性别以及种族和族裔。在报告获得机会减少的研究中，最常见的原因包括初级和专业提供者密度，患者社会经济状况的差异，以及在手术决策期间提供可比咨询。引人注目的是，增加手术机会的一个关键驱动因素是缺乏专门的医疗干预，导致过度依赖手术替代方案。结论：无论手术通路是否减少或加速，乡村性的净影响是偏离指南-一致性护理。这些发现的一个关键含义是，仅仅依赖手术等待时间就会扭曲对手术可及性的看法，倡导采用综合护理质量指标，更好地反映综合医疗和手术治疗方案的可及性。Contexte: Etant多恩,德莱斯中心参与tertiaires se trouvent generalement环境班,我们se要求者si l 'acces辅助服务chirurgicaux est le meme en地区瞿rurale环境班。Nous avons voulu cartographier，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病，预防疾病。MÉTHODES: Nous avons procesamd one interrogation system sammatique (conme la Norme de remacize de revue system sammatique de la littsamatrature PRISMA) des bases de donnsametes PubMed， MEDLINE， Scopus et Web of Science重组la littsamatrature des 26 derniires annacimes （janvier 2023）。《Les mots claines de english laise utilissamis》包括：“农村人口”、“保健机会”、“外科手术”和“保健差距”。Nous avons synthsamtis没有观察到moyen d'une方法叙述。RÉSULTATS: Des 13897 -最近的薪金，目前的薪金，保留了71份出版物，其中包含了各种各样的薪金和薪金。帕尔米的出版物中，83%的人认为，电子烟和电子烟和电子烟有关，17%的人认为，电子烟和电子烟有关，30%的人认为，电子烟和电子烟有关，电子烟和电子烟有关，性别和类型，种族和种族。例如，将其他因素与其他因素相比较，例如将其他因素与其他因素相比较，例如将其他因素与其他因素相比较，将其他因素与其他因素相比较，例如将其他因素与其他因素相比较，例如将其他因素与其他因素相比较，例如将其他因素与其他因素相比较。做笔记者,两个des principaux影响d 'amelioration de l 'acces辅助参与chirurgicaux是l 'absence d 'interventions 26日专门associees有一个依赖性赋予一个l 'endroit chirurgicales des的解决方案。结论：通过对已获得的电子表格和电子表格和电子表格和其他电子表格的分析，确定了电子表格和其他电子表格的格式。Ces观察indiquent principalement乘缆车依赖性l 'egard des临时工d 'attente en chirurgie单独可以fausser la感知量化一个l 'acces辅助参与chirurgicaux, ce, milite en faveur de l 'adoption de产品德质量de参与中国,refleteraient + fidelement l 'acces des项目de traitements medicaux et chirurgicaux完了。

Background: The effect of weekend admission and surgery on patient morbidity and mortality has been studied in many settings and has been shown to lead to worse outcomes. Several studies have sought to determine whether there is a weekend effect in kidney transplantation specifically, but a clear effect on outcomes and graft survival has not been established.
Methods: We analyzed data from all deceased-donor organ procurements and cadaveric kidney transplants occurring during the 5-year period between Apr. 1, 2013, and Dec. 31, 2017, included in the database of the Trillium Gift of Life Network, Ontario's organ and tissue donation agency.
Results: A total of 1116 deceased donor nephrectomies (DNs) and 1858 recipient procedures were performed in Ontario during the study period. The overall rate of after-hours DNs on weekdays was significantly greater than during working hours (23.1/30 d v. 15.4/30 d, p < 0.001). Donations after neurological determination of death were more frequent during weekday working hours (22.8/30 d) than after hours on weekdays (17.3/30 d, p < 0.001) or weekends (16.3/30 d, p < 0.001), whereas donations after cardiac death were significantly more frequent after hours on weekdays than during working hours (10.3/30 d v. 7.7/30 d, p = 0.021). On weekdays, mean warm ischemia time (WIT) was significantly longer after hours than during working hours (40.75 ± 12.26 min v. 38.52 ± 11.92 min, p = 0.017). Similarly, mean WIT was longer after hours than during working hours on weekends (40.23 ± 12.48 min v. 38.59 ± 11.91 min, p = 0.015).
Conclusion: Kidney transplantations occurred more frequently after hours and were associated with increased WIT. Further study is needed across multiple Canadian centres to better understand the temporal patterns of kidney transplantation and implications for patients, providers, and health care systems.
背景：周末住院和手术对患者发病率和死亡率的影响已经在许多情况下进行了研究，并显示会导致更糟糕的结果。一些研究试图确定在肾移植中是否存在特异性的周末效应，但尚未确定对预后和移植物存活的明确影响。方法：我们分析了2013年4月1日至2017年12月31日期间发生的所有死者供体器官采购和尸体肾移植的数据，这些数据纳入安大略省器官和组织捐赠机构Trillium Gift of Life Network的数据库。结果：在研究期间，安大略省共进行了1116例已故供体肾切除术（dn）和1858例受体手术。工作日下班后dn的总体发生率显著高于工作时间（23.1/30 d vs . 15.4/30 d, p < 0.001）。神经系统死亡后的捐赠在工作日工作时间（22.8/30 d）高于工作日下班后（17.3/30 d, p < 0.001）或周末（16.3/30 d, p < 0.001），而心脏死亡后的捐赠在工作日下班后明显高于工作时间（10.3/30 d vs . 7.7/30 d, p = 0.021）。工作日下班后的平均热缺血时间（WIT）明显长于上班时间（40.75±12.26 min vs . 38.52±11.92 min, p = 0.017）。同样，下班后的平均WIT比周末工作时间更长（40.23±12.48 min vs . 38.59±11.91 min, p = 0.015）。结论：肾移植在术后发生的频率更高，且与WIT增加有关。为了更好地了解肾移植的时间模式以及对患者、提供者和卫生保健系统的影响，需要在多个加拿大中心进行进一步的研究。

SummaryThis discussion describes the long-term follow-up of a prospective randomized controlled trial evaluating the performance of the 2 most common biomesh products utilized in the context of complex abdominal wall reconstructions. Although the incidence of hernia recurrence increased over time to 26% (median follow-up 62 mo), both biomesh products performed similarly. Biomesh product choice should remain cost-conscious.

Background: Little is known about the existing structure and function of referral networks in the prevalent referral system for specialized surgical care in Canada, which is based on direct physician referral to specialists in a largely unmanaged referral marketplace. Our objective was to describe and analyze the referral networks of referring physicians and surgeons for common surgical procedures in Ontario, to better understand potential barriers to single-entry models.
Methods: We analyzed referral networks for patients between referring physicians and surgeons for 9 common scheduled surgical procedures from 2016 to 2019 using administrative data sources in Ontario. We described the connectedness of referring physician-surgeon pairs using descriptive measures and graphical social network analysis.
Results: The median number of surgeons connected to a referring physician for patients having a particular surgical procedure ranged from 1 (interquartile range [IQR] 1-3) for spine surgery to 3 (IQR 1-4) for knee arthroplasty and 3 (IQR 2-5) for noncancer uterine procedures. Referral network structure varied according to the procedure studied. Spine surgery was highly clustered with a small number of larger groups; gallbladder, inguinal hernia, and noncancer uterine surgery were highly distributed with many small groups within the referral network. Breast cancer surgery occurred in a largely distributed network, but with a skewed distribution reflecting a few small groups with large numbers of patients.
Conclusion: Improving surgical wait times by coordinating surgical referrals will require approaches that address the structure of existing referral networks. Most physicians refer their patients to a very small number of surgeons, suggesting that referring physicians largely do not individualize referrals to multiple different surgeons based on specific patient characteristics.

Background: Cerebrospinal fluid (CSF) drainage is used to reduce spinal cord ischemia (SCI) in patients undergoing thoracoabdominal aortic procedures. Recent literature has found high rates of complication associated with CSF drainage, which has led to changes in practice. The aim of this study was to investigate rates of CSF drain-related complications in patients undergoing a thoracoabdominal aortic procedure with perioperative placement of a CSF drain.
Methods: We conducted a single-centre retrospective cohort study. We defined major complications as intracranial hemorrhage, epidural hematoma or abscess, meningitis, and catheter retention requiring a reoperation. Minor complications assessed included drain-induced neurologic deficits, CSF leak, postdural puncture headache, asymptomatic blood in the CSF, drain failure, and catheter retention not requiring a reoperation. We recorded postoperative neurologic deficits as secondary outcomes.
Results: There were 129 patients who met the inclusion criteria. We found 5 cases of permanent paraplegia in the overall cohort (3.9%), with only 2 occurring in the patients with prophylactic CSF drains (1.6%). There were no major CSF drain-related complications. The rate of minor complications was 17.8%. We found no association between complication rates and indication for procedure or type of operation.
Conclusion: The lack of major complications in this series adds to existing variability in recent literature and provides support for continued use of this adjunct for SCI prevention. Further research is required to identify the etiology of significant differences in CSF drain complication rates seen at other centres.
