Pulmonary metastases in urogenital cancers: Surgical treatment and outcomes

IntroductionMetastasis is remaining one of the major problems in cancer treatment. Like many other malignancies, urogenital tumors originating from kidney, prostate, testes, and bladder tend to metastasize to the lungs.The aim of this retrospective study is to evaluate the operative results and prognosis of pulmonary metastasectomy in patients with primary urogenital tumors.MethodsThis study was approved by the local ethical committee. We retrospectively analyzed the surgical and oncological results of patients who underwent lung resections for urogenital cancer metastases in our department between 2002 and 2018. Demographic data and clinicopathological features were extracted from the medical records. Survival outcomes according to cancer subtypes and early postoperative results of VATS and thoracotomy were analyzed.Results22 out of 126 patients referred for pulmonary metastasectomy to our department had metastases from urogenital tumors. These patients consisted of 17 males and five females. Their metastasis originated from renal cell carcinoma (RCC; n = 9), bladder tumor (n = 7), testis tumors (n = 4), and prostate cancer (n = 2). There was no intraoperative complication. Postoperative complications were seen in 2 patients.ConclusionsAlthough pulmonary metastasectomy in various types of tumors is well known and documented, the data is limited for metastases of urogenital cancers in the literature. Despite the limitations of this study, we aim to document our promising results of pulmonary metastasectomy in patients with primary urogenital tumors and wanted to emphasize the role of minimally invasive approaches.     

Understanding congenital vertical talus

Congenital vertical talus (CVT) is a rare foot deformity that presents with a rigid flat foot at birth. CVT can present as an isolated abnormality in the newborn, however in at least 50% of cases in association with other conditions. Full neuro-axial imaging is essential to detect any associated neurologic problems. Radiographs of the foot, including forced plantar and dorsiflexion laterals, are diagnostic. Gold standard modern treatment uses the Dobbs method of serial manipulation and casting with minimally-invasive stabilization of the talonavicular joint and Achilles tendon tenotomy.     

飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障

目的：评估飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障的有效性和安全性。

方法：回顾性病例对照研究。2019-10/2021-10入院合并难治性青光眼的白内障患者53例53眼，依据自愿选择分为飞秒激光辅助白内障超声乳化(FLACS)组26例26眼和常规白内障超声乳化(CPCS)组27例27眼。两组分别行FLACS和CPCS联合Ahmed青光眼引流阀植入术。比较两组患者术中超声乳化能量释放量(CDE)、有效超声时间(EPT)的差异和术前与术后抗青光眼药物数量的变化，以及术后观察不同时期(1d，1wk，1、3mo)在提高最佳矫正视力(BCVA)，降低眼压、角膜内皮细胞损伤程度和手术并发症及成功率状况。

结果：FLACS组术中CDE和EPT明显低于CPCS组(t=8.50、5.16； P<0.01、=0.001)。两组术后抗青光眼药物较术前均明显减少(t=9.12、7.76； P=0.011、0.016)，但两组间无差异(t=1.79，P=0.082)。两组术后BCVA均较术前改善，眼压均较术前降低(P<0.05)。FLACS组在术后早期(1d，1wk)BCVA的改善较CPCS组更显著(t=9.74、8.49； P=0.008、0.012)，但在术后1、3mo的BCVA改善程度并无不同(t=0.62、0.44； P=1.415、2.021)。CPCS组在术后随访不同时期的角膜内皮细胞损伤较FLACS组更明显(P<0.05)。术后随访的不同时期FLACS组和CPCS组在控制眼压方面无差异(F_组间=0.64，P_组间=0.421)。FLACS组的手术并发症发生率27%(7/26)较CPCS组89%(24/27)低(χ²=20.95，P<0.01)，其中角膜水肿(8% vs 41%)、前囊撕裂(0 vs 11%)在FLACS组中明显低于CPCS组，后囊破裂(0 vs 7%)、玻璃体脱出(0 vs 4%)及人工晶状体偏位(0 vs 7%)也均发生在CPCS组。但两组的治疗总成功率相近(P=28.718)。

结论：飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术可充分发挥联合手术的精准微创可控优势，帮助合并难治性青光眼的白内障患者有效降低眼压及更早获得视力恢复。     

维生素A对糖基化终末产物诱导的角膜上皮细胞损伤的作用及机制研究

目的糖基化终末产物(AGEs)在糖尿病患者在角膜外伤或接受角膜手术时极易出现角膜上皮愈合延迟甚至不愈的过程中起着关键作用,本文研究维生素A(VA)对以糖基化终末产物AGE-BSA诱导角膜上皮细胞损伤的影响及可能的作用机制。方法以HCE-2细胞为研究对象,AGE-BSA为诱导剂,试剂盒检测VA对细胞凋亡率及线粒体膜电位的影响,荧光显微镜检测细胞内凋亡小体,Western blot检测相关的蛋白表达量。结果VA抑制AGE-BSA诱导的HCE细胞凋亡,调节AGEBSA引起的凋亡相关蛋白的变化。同时,VA与JNK的抑制剂同等程度的减少AGE-BSA诱导的JNK和NF-κB的磷酸化。结论VA可能通过抑制JNK介导的NF-κB炎症通路而起到减少AGE-BSA诱导的角膜上皮细胞凋亡的作用,可以作为糖尿病患者角膜上皮损伤的保护剂。     

加强术前专科健康教育在先天性心脏病患儿家属中的应用

目的探究分析加强术前专科健康教育对先天性心脏病手术患儿家属健康相关坚韧性及希望指数的影响。方法选取2015年6月-2019年6月期间来院就诊的先天性心脏病患儿家属74例作为临床研究对象,采用随机数字表法将患者分为观察组和对照组两组,各37例,对照组患儿家属给予常规干预,观察组在对照组基础上加用加强术前专科健康教育,对比两组患儿家属行不同干预前后Herth希望指数量表(herth hope index,HHI)、健康相关坚韧性量表(health-related hardinessScale,HRHS)以及对护理工作的满意度。结果行不同干预后,两组患儿家属现实和未来积极态度、采取积极的行动、与他人保持密切关系以及希望总分等HHI量表各项评分均明显升高(P<0.05),控制量表、承担量表、挑战量表及坚韧性评分等HRHS量表各项评分均明显提高(P<0.05),且同期观察组患儿家属上述评分均明显优于对照组患儿家属(P<0.05)。观察组与对照组相比患儿家属对护理工作的满意度较高,组间差异具有统计学意义(P<0.05)。结论加强术前专科健康教育能够有效的提高先天性心脏病患儿家属健康相关坚韧性及希望水平,提高患儿家属对护理工作的满意度。     

Cardiovascular risk factors in adults with coarctation of the aorta

Background: The aging patient with adult congenital heart disease (ACHD) faces the risk of developing atherosclerotic disease. Patients with coarctation of the aorta (CoA) are especially vulnerable because of an inherent high risk of developing hy‐ pertension. However, data on the prevalence of other cardiovascular risk factors are scarce. Therefore, this study aimed to describe the prevalence of traditional cardio‐ vascular risk factors (diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle) in adult patients with CoA.
Methods: Patients with CoA who were registered at the ACHD clinic in Gothenburg were asked to participate in a comprehensive cardiovascular risk assessment. This assessment included a glucose tolerance test, cholesterol profile, ambulatory blood pressure measurements, and a lifestyle questionnaire.
Results: A total of 72 patients participated. The median age was 43.5 years and 58.3% were men. Sixty‐six (91.7%) patients had ≥one cardiovascular risk factor and 40.3% had ≥three risk factors. Three (4.2%) patients were newly diagnosed with diabetes or impaired glucose tolerance. More than half of the patients had hyperlipidemia (n = 42, 58.3%) and 35 patients (48.6%) were overweight or obese. Only three (4.2%) patients smoked regularly. Of the 60 patients who underwent 24‐hour ambulatory blood pressure measurement, 33 (55.0%) were hypertensive. Of the 30 patients with known hypertension only 9 (30.0%) had well‐controlled blood pressure on ambula‐ tory blood pressure measurement.
Conclusions: Cardiovascular risk factors among patients with CoA are prevalent. This may indicate a need for more aggressive screening strategies of traditional risk fac‐ tors to minimize the risk of these patients also developing atherosclerotic disease.
