Background: The benefit of adding hyperthermic intraperitoneal chemotherapy (HIPEC) to cytoreductive surgery (CRS) in ovarian cancer with peritoneal metastasis remains debated outside selected indications. We performed a systematic review and meta-analysis to quantify survival, perioperative morbidity, and completeness of cytoreduction using study-level data.
Methods: PubMed/MEDLINE, Embase, and Web of Science were searched. Eligible English-language studies included ovarian cancer patients undergoing CRS plus HIPEC and reported at least one of the following: overall survival (OS), progression-free survival (PFS), Grade III-IV complications, or CC-0 rate. Random-effects meta-analyses were conducted using inverse-variance pooling. For HR outcomes, DerSimonian-Laird τ2 with Hartung-Knapp confidence intervals was applied. Proportions were pooled using logit transformation (PLOGIT) with random-effects models.
Results: Twelve studies (n = 567) were included. Only two studies provided extractable HRs for OS and PFS (n = 217). CRS plus HIPEC was associated with improved OS (HR 0.68, 95% CI 0.52-0.90, p = 0.0023; I2 = 0%; prediction interval 0.14-3.34) and improved PFS (HR 0.70, 95% CI 0.31-1.57, p = 0.0007; I2 = 0%; prediction interval 0.18-2.66). Across 12 studies (n = 563), the pooled Grade III-IV complication rate was 0.18 (95% CI 0.14-0.22; I2 = 16.3%; prediction interval 0.12-0.26). In 10 studies (n = 385), the pooled CC-0 rate was 0.87 (95% CI 0.79-0.92; I2 = 46.7%; prediction interval 0.66-0.96).
Conclusions: CRS plus HIPEC shows a favorable signal for OS and PFS in the limited HR-eligible evidence and appears feasible, with a pooled severe complication rate of ~18% and high CC-0 rates. Current data support HIPEC primarily as a targeted intensification strategy in carefully selected patients, while broader adoption requires additional randomized, context-specific evidence.
背景:对于伴有腹膜转移的卵巢癌,在细胞减少手术(CRS)的基础上增加腹腔热化疗(HIPEC)的益处仍存在争议。我们进行了系统回顾和荟萃分析,以量化生存率、围手术期发病率和使用研究水平数据的细胞减少的完整性。方法:检索PubMed/MEDLINE、Embase、Web of Science。符合条件的英语研究包括接受CRS + HIPEC的卵巢癌患者,并报告至少以下一项:总生存期(OS),无进展生存期(PFS), III-IV级并发症或CC-0率。随机效应荟萃分析采用反方差池。对于人力资源结果,采用具有Hartung-Knapp置信区间的dersimonan - laird τ2。使用随机效应模型的logit变换(PLOGIT)合并比例。结果:纳入12项研究(n = 567)。只有两项研究提供了OS和PFS的可提取hr (n = 217)。CRS + HIPEC与改善OS (HR 0.68, 95% CI 0.52-0.90, p = 0.0023; I2 = 0%,预测区间0.14-3.34)和改善PFS (HR 0.70, 95% CI 0.31-1.57, p = 0.0007; I2 = 0%,预测区间0.18-2.66)相关。在12项研究中(n = 563), III-IV级合并并发症发生率为0.18 (95% CI 0.14-0.22; I2 = 16.3%;预测区间0.12-0.26)。在10项研究(n = 385)中,合并CC-0率为0.87 (95% CI 0.79-0.92; I2 = 46.7%;预测区间0.66-0.96)。结论:在有限的hr合格证据中,CRS + HIPEC对OS和PFS显示出有利的信号,并且似乎是可行的,合并严重并发症发生率约为18%,CC-0率较高。目前的数据支持HIPEC主要是在精心挑选的患者中作为有针对性的强化策略,而更广泛的采用需要额外的随机、具体情况的证据。

Background: Acute kidney injury (AKI) is a frequent and prognostically relevant complication of COVID-19. However, reliance on static creatinine values or binary AKI definitions may overlook clinically meaningful early renal dynamics. We evaluated whether early renal function trajectories within the first 24-48 h of hospitalization provide incremental prognostic information.
Methods: We conducted a retrospective, single-center cohort study of adults hospitalized with laboratory-confirmed COVID-19 between December 2020 and December 2021. Early renal function patterns were defined using KDIGO-based changes in serum creatinine between admission and 24-48 h, classifying patients as stable, early improvement, or early deterioration. The primary outcome was in-hospital mortality. Multivariable logistic regression adjusted for age, sex, chronic kidney disease, comorbidities, inflammatory burden (C-reactive protein), nutritional status (albumin), pulmonary involvement, and treatment variables.
Results: Among 721 patients, 65.2% had stable renal function, 22.5% had early improvement, and 12.3% had early deterioration. In-hospital mortality differed significantly across dynamic patterns (p = 0.007). Mortality was lowest in the stable group (35.1%) and higher in both early improvement (48.1%) and early deterioration (44.9%). After multivariable adjustment, early improvement remained independently associated with higher in-hospital mortality compared with stable renal function (adjusted OR 1.53, 95% CI 1.03-2.28), while early deterioration showed a directionally similar but non-significant association. Early improvement was also associated with higher AKI burden and increased need for acute de novo hemodialysis.
Conclusions: Early renal function change patterns within the first 24-48 h of hospitalization carry prognostic value beyond static creatinine measures. Apparent early creatinine improvement may reflect recovery from prior injury or systemic instability rather than true renal recovery, identifying a subgroup at heightened risk. Classification based on early renal function assessment may enhance early risk stratification in hospitalized patients with COVID-19.
背景:急性肾损伤(AKI)是COVID-19常见且与预后相关的并发症。然而,依赖于静态肌酐值或二元AKI定义可能会忽略有临床意义的早期肾脏动力学。我们评估了住院后24-48小时内的早期肾功能轨迹是否提供了渐进式的预后信息。方法:我们对2020年12月至2021年12月期间因实验室确诊的COVID-19住院的成人进行了一项回顾性、单中心队列研究。采用入院至24-48小时之间基于kdigi的血清肌酐变化来定义早期肾功能模式,将患者分为稳定、早期改善或早期恶化。主要终点是住院死亡率。多变量logistic回归校正了年龄、性别、慢性肾脏疾病、合并症、炎症负担(c反应蛋白)、营养状况(白蛋白)、肺部受累和治疗变量。结果:721例患者中,65.2%肾功能稳定,22.5%早期改善,12.3%早期恶化。住院死亡率在不同动态模式下差异显著(p = 0.007)。稳定组的死亡率最低(35.1%),早期改善组(48.1%)和早期恶化组(44.9%)的死亡率均较高。多变量校正后,与稳定肾功能相比,早期改善与更高的住院死亡率仍然独立相关(校正OR 1.53, 95% CI 1.03-2.28),而早期恶化显示方向相似但不显著的关联。早期改善也与AKI负担增加和急性从头血液透析需求增加有关。结论:住院后24-48小时内的早期肾功能变化模式具有比静态肌酐测量更重要的预后价值。早期明显的肌酐改善可能反映了先前损伤或全身性不稳定的恢复,而不是真正的肾脏恢复,从而确定高危亚组。基于早期肾功能评估的分级可加强COVID-19住院患者的早期风险分层。

Background: Endometrial cancer (EC) represents one of the most prevalent gynecological malignancies worldwide, with increasing incidence rates attributed to rising obesity, metabolic syndrome, and demographic aging. Recent evidence suggests that dyslipidemia, including elevated triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and reduced high-density lipoprotein cholesterol (HDL-C), may have a significant role in the pathogenesis of EC through inflammatory, oxidative stress, and hormonal mechanisms.
Objective: This meta-analysis aims to systematically evaluate the association between serum lipid biomarkers and endometrial cancer risk by synthesizing quantitative data from observational studies.
Methods: We conducted a comprehensive search of five electronic databases (PubMed, Web of Science, Scopus, EMBASE, and Cochrane) to identify studies examining lipid biomarkers in patients with EC compared to healthy controls. After screening 639 articles and applying rigorous inclusion/exclusion criteria, six studies were selected for final analysis. The standardized mean differences (SMD) were calculated with 95% confidence intervals using random-effects and fixed-effects models, considering heterogeneity assessed by the I2 statistic. Publication bias was evaluated using funnel plots and Egger's regression test.
Results: The meta-analysis revealed significantly elevated TG levels in EC patients compared to controls (SMD +0.87, 95% CI [+0.65, +1.10]), markedly reduced HDL-C levels (SMD -0.92, 95% CI [-1.15, -0.69]), and increased LDL-C levels (SMD +0.74, 95% CI [+0.50, +0.98]). The heterogeneity was moderate to substantial, with an I2 ranging from 49% to 62%. Subgroup analyses demonstrated stronger associations in Type I EC and obese patients (BMI > 30 kg/m2).
Conclusions: This meta-analysis establishes a significant association between dyslipidemia and endometrial cancer risk, with elevated triglycerides and LDL-C conferring increased risk while HDL-C appears protective. These findings support the integration of lipid profiling into EC risk assessment protocols and suggest the potential preventive value of lipid-modulating interventions. Further studies are needed to establish causality and evaluate therapeutic applications.
背景:子宫内膜癌(EC)是世界范围内最常见的妇科恶性肿瘤之一,随着肥胖、代谢综合征和人口老龄化的增加,发病率不断上升。最近的证据表明,血脂异常,包括甘油三酯(TG)升高、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)降低,可能通过炎症、氧化应激和激素机制在EC的发病机制中发挥重要作用。目的:本荟萃分析旨在通过综合观察性研究的定量数据,系统评估血脂生物标志物与子宫内膜癌风险之间的关系。方法:我们对5个电子数据库(PubMed, Web of Science, Scopus, EMBASE和Cochrane)进行了全面的检索,以确定与健康对照组相比,EC患者的脂质生物标志物的研究。在筛选639篇文献并应用严格的纳入/排除标准后,选择6项研究进行最终分析。考虑到I2统计量评估的异质性,使用随机效应和固定效应模型以95%置信区间计算标准化平均差异(SMD)。采用漏斗图和Egger回归检验评价发表偏倚。结果:荟萃分析显示,与对照组相比,EC患者TG水平显著升高(SMD +0.87, 95% CI [+0.65, +1.10]), HDL-C水平显著降低(SMD -0.92, 95% CI [-1.15, -0.69]), LDL-C水平升高(SMD +0.74, 95% CI[+0.50, +0.98])。异质性中度至重度,I2范围为49%至62%。亚组分析显示,I型EC与肥胖患者(体重指数bbb30 kg/m2)有更强的相关性。结论:本荟萃分析建立了血脂异常与子宫内膜癌风险之间的显著关联,甘油三酯和LDL-C升高会增加风险,而HDL-C则具有保护作用。这些发现支持将脂质分析纳入EC风险评估方案,并提示脂质调节干预措施的潜在预防价值。需要进一步的研究来确定因果关系并评估治疗应用。

Introduction: Respiratory rehabilitation programs for geriatric patients with chronic obstructive pulmonary disease (COPD) after COVID-19 require a precise assessment of needs and an individualized approach. However, there is a lack of specific recommendations for aerobic training in this patient group.
Objective: The study aimed to compare two types of aerobic training-continuous and interval-and to determine which one is more effective and should be included in the respiratory rehabilitation program for geriatric patients with COPD after COVID-19.
Methods: Of the 480 patients examined, 80 were included in the study. All patients underwent exercise tolerance tests (6-Minute Walk Test-6MWT) and functional performance tests (get-up-and-go test-TUG) before and after a 3-week intensive respiratory rehabilitation program.
Results: Both types of training-interval and continuous-contributed to improved exercise tolerance and functional fitness in patients. However, analysis of the differences between the groups showed that continuous training with increasing exercise intensity resulted in significantly greater improvements in distance covered during the 6MWT, energy expenditure (METs), and TUG test time (p < 0.05).
Conclusions: Continuous training on a cycle ergometer is more effective in the rehabilitation of geriatric patients with COPD after COVID-19 and should be included in therapeutic programs.

Transoral robotic surgery (TORS) offers a targeted surgical option for addressing base of tongue (BOT) and epiglottic obstruction in selected obstructive sleep apnoea (OSA) cases; however, most published evidence evaluates TORS within multilevel approaches, limiting understanding of single-level outcomes. A PRISMA-guided systematic review of PubMed, Embase, and Central Cochrane was conducted from inception to March 2025, aiming to evaluate objective sleep outcomes and patient-reported measures following single-level TORS BOT surgery. Inclusion criteria were adult patients with moderate-to-severe OSA and CPAP failure/intolerance, with evidence of BOT hypertrophy. Of 219 screened records, five studies met the inclusion criteria with 105 patients. Eighty-six (81.9%) were male with a combined mean age of 45.2 years and BMI of 28.2 kg/m2. Combined mean AHI improved from 34.2 preoperatively to 14.7 events/hour postoperatively. Reported surgical success ranged from 54.2% to 100%. Where reported, ESS improved postoperatively with a combined mean reduction from 13 to 4.5. Most commonly reported complications were dysgeusia (n = 16, 15.2%), dysphagia/odynophagia (n = 14, 13.3%), and postoperative bleeding (n = 10, 9.5%). Single-level TORS BOT appears to improve objective and subjective outcomes in carefully selected patients, although heterogeneity and inconsistency of reported outcomes limit definitive conclusions and highlight the need for standardised outcome reporting and follow-up.

Background: Bruton's tyrosine kinase inhibitors, particularly ibrutinib, have improved outcomes in patients with chronic lymphocytic leukemia but are associated with an increased risk of atrial fibrillation. The early identification of patients with increased susceptibility to atrial fibrillation remains a major challenge in cardio-oncology. Methods: This prospective pilot study included 45 patients with chronic lymphocytic leukemia treated with ibrutinib. All patients underwent comprehensive transthoracic echocardiography at baseline and after 6 months. Left atrial structure and function were assessed, with particular emphasis on speckle-tracking-derived left atrial strain parameters, including peak atrial longitudinal strain and peak atrial contraction strain. Results: At follow-up, a modest but significant increase in indexed left atrial volume was observed, while left atrial functional parameters remained stable. Patients who developed atrial fibrillation showed significantly lower baseline Peak Atrial Contraction Strain values compared with those who remained in sinus rhythm, whereas no significant differences in Peak Atrial Longitudinal Strain were detected. Conclusions: Ibrutinib-related atrial fibrillation appears to be driven primarily by pre-existing atrial vulnerability rather than early drug-induced atrial dysfunction. The baseline impairment of left atrial contractile function may represent a candidate echocardiographic marker of atrial functional vulnerability and may inform cardiovascular surveillance and monitoring strategies in patients treated with ibrutinib.

Background: Skin and myocardial microvascular dysfunction in prediabetes remains underexplored, and limited studies have investigated the microcirculation in prediabetes in multiple vascular beds. This study aimed to examine microvascular alterations in patients with prediabetes, patients with type 2 diabetes mellitus (DM), and normoglycemic controls without established cardiovascular disease (CVD).
Methods: In this cross-sectional study, the microcirculation was assessed using established and novel noninvasive techniques. The skin microvascular reactivity was evaluated using laser speckle contrast analysis (LASCA). The myocardial perfusion was assessed by the subendocardial viability ratio (SEVR). The retinal microvasculature was evaluated using digital nonmydriatic fundus photography, the renal microvascular damage through the urinary albumin-to-creatinine ratio (ACR), and the peripheral vasculopathy by the augmentation index (AIx).
Results: Sixty-seven participants were included (22 controls, 24 with prediabetes, 21 with DM; aged: 55.9 ± 9.4 years). Patients with prediabetes and DM showed significantly reduced baseline-to-peak skin flux responses in LASCA compared with controls (p = 0.006), and lower SEVR values (p = 0.001). Moreover, no significant differences were identified in the retinal, renal, or peripheral microvascular indices. In multivariate analysis, systolic blood pressure and glucose were independently associated with skin microvascular dysfunction, while the heart rate and arteriovenous ratio were associated with the SEVR.
Conclusions: In this cross-sectional study, impaired skin and myocardial microvascular function were observed in patients with prediabetes in the absence of overt CVD. These findings suggest that LASCA and the SEVR may serve as sensitive markers for the detection of early, subclinical microvascular dysfunction in prediabetes.

Purpose: This study develops a predictive model for radiation pneumonitis (RP) risk in lung cancer patients after volume-modulated arc therapy (VMAT) that leverages high-dimensional dosiomics and dose-volume histogram (DVH) features within IDLSS (incremental-dose interval-based lung subregion) lung subregions. Methods: We retrospectively analyzed data from 136 lung cancer patients treated with VMAT between 2015 and 2022, including 39 patients who developed RP greater than Grade 2. Using the IDLSS method, seven regions of interest (ROIs), including the Planning Target Volume (PTV), normal lung, and five subdivided lung areas, were delineated on pretreatment Computed Tomography (CT) images. DVH, radiomics, and dosiomics features were extracted from these ROIs and organized into nine distinct feature sets. A comprehensive pipeline was applied, integrating IDLSS-defined lung subregions, high-dimensional dosiomics features, LASSO-based feature selection, and SMOTE oversampling to address class imbalance in the training data. Logistic regression, random forest, and feedforward neural networks were constructed and optimized via tenfold cross-validation. Model performance across different feature sets was evaluated via the average AUC, F1 score, and other performance metrics. Results: LASSO regression revealed that BMI and volume within the 5-10 Gy and 10-20 Gy lung subregions were significant predictors of RP. The performance evaluation demonstrated that the dosiomics features consistently outperformed the DVH features across the models. Combining radiomics and dosiomics achieved the highest predictive accuracy (AUC = 0.91, ACC = 0.89, NPV = 0.95, PPV = 0.78, F1 score = 0.82, sensitivity = 0.88, specificity = 0.90). Applying SMOTE during training significantly improved sensitivity without compromising specificity, confirming the value of balancing strategies in enhancing model performance. Incorporating all the features together did not provide additional performance gains. Conclusions: Integrating radiomics and dosiomics features extracted from IDLSS-defined lung subregions significantly enhances the ability to predict RP after VMAT, surpassing traditional DVH metrics. The substantial contribution of dosiomics features highlights the importance of spatial dose heterogeneity in RP risk assessment.

Objectives: Cerebral ischemia/reperfusion (IR) injury is characterized by excessive oxidative stress and activation of apoptotic pathways, which play a central role in neuronal loss and poor neurological outcomes. Modulation of these mechanisms represents a clinically relevant strategy for neuroprotection. This study aimed to investigate the neuroprotective effects of dexmedetomidine (Dex) on oxidative stress, apoptotic signaling, and neuronal integrity in an experimental rat model of cerebral IR injury.
Materials and methods: Female Wistar rats were assigned to control, IR, and IR+Dex groups. Transient cerebral ischemia was induced for 45 min followed by 2 h of reperfusion. Oxidative stress was evaluated using serum antioxidant enzyme activities (superoxide dismutase [SOD], catalase [CAT], glutathione peroxidase [GSH-Px]), total oxidant and antioxidant status (TOS, TAS), and lipid peroxidation levels (malondialdehyde [MDA]). Apoptotic signaling was assessed by histopathological examination, transmission electron microscopy, and immunohistochemical analysis of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax) and apoptotic peptidase activating factor-1 (APAF-1) expression, quantitatively evaluated using QuPath with statistical comparison between groups. Bioinformatic network analysis and molecular docking were performed to explore predicted interactions between Dex and apoptosis-related proteins.
Results: Cerebral IR induced a marked oxidative imbalance, characterized by reduced antioxidant enzyme activities and increased lipid peroxidation. Dex treatment partially improved antioxidant capacity and reduced oxidative stress parameters. Histopathological and ultrastructural analyses demonstrated severe neuronal degeneration following IR, whereas Dex-treated rats exhibited attenuated neuronal damage and improved ultrastructural preservation. Immunohistochemical analysis showed increased Bax and APAF-1 expression and reduced Bcl-2 expression after IR; these alterations were significantly modulated toward control levels in the IR+Dex group. Bioinformatic analysis identified apoptosis-related pathways, including apoptosis, p53 signaling, and necroptosis, as significantly enriched, while molecular docking suggested stable predicted interactions between Dex and key apoptotic regulators.
Conclusions: In this experimental rat cerebral IR model, Dex exerted partial but significant neuroprotective effects by attenuating oxidative stress, modulating apoptotic marker expression, and preserving neuronal morphology. These findings support the potential role of Dex as a neuroprotective agent in ischemia-related brain injury, warranting further translational investigation.
