Dietary characteristics affect maternal status in early pregnancy, which is important for later outcomes. However, Chinese dietary guidelines for pregnant women are not specific to obesity, overweight, and underweight. Moreover, since pregnancy is a prolonged process, an intermediate factor is needed to connect early maternal BMI with pregnancy outcomes.

Hospital Teaching Status and Outcomes in Type B Aortic Dissection: Analysis of More Than 40,000 Patients.
J Cardiothorac Vasc Anesth
January 2025
Article Synopsis
- The study aimed to evaluate the impact of hospital teaching status on outcomes for patients with type B aortic dissection (TBAD) using data from the National Readmissions Database over four years.
- A total of 44,981 TBAD patients were analyzed, revealing no significant differences in in-hospital mortality or 30-day readmission rates between those treated at teaching hospitals versus non-teaching hospitals.
- At teaching hospitals, the use of thoracic endovascular aortic repair (TEVAR) showed higher risks of in-hospital mortality, while higher hospital patient volumes were linked to increased chances of 30-day readmissions.
A highly sensitive and selective label-free impedimetric immunosensor based on AuNPs@pDA@NiCoS@MoS nanocomposite modified on the surface of a screen-printed electrode (SPE) was designed for the detection of interleukin-6 (IL-6). The distribution of NiCoS nanoparticles on MoS nanosheets was able to prevent them from agglomerating. The polydopamine (pDA) layer was coated on the surface of NiCoS@MoS nanosheets by self-polymerization, which improved the stability and biocompatibility of the nanomaterial.

October 2024
Article Synopsis
- The study aimed to determine if using epiaortic ultrasound to assess aortic calcification would lower the rate of postoperative strokes in patients undergoing coronary artery bypass grafting (CABG).
- A total of 10,049 patients were analyzed, with 1,572 receiving epiaortic ultrasound. The results showed no significant difference in stroke rates between the groups, with 0.8% in the ultrasound group and 1.4% in the non-ultrasound group.
- Overall, the study concluded that epiaortic ultrasound did not significantly reduce the odds of postoperative stroke or hazards of mortality in CABG patients.
Background: The aim of this study was to determine the relationship between the lymph node ratio (LNR) and the prognostic values of gynecological cancer.
Materials And Methods: PubMed, Web of Science, Embase, and the Central Cochrane Library were used to search for studies on LNR and gynecological cancer published before 18 April 2024. The effect measure for meta-analysis of primary outcomes was the hazard ratio (HR) for overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS).
Objective: To determine the relationship between the Silva pattern-based classification system and endocervical adenocarcinoma.
Methods: The PubMed, Embase, Central Cochrane Library, and Web of Science databases were systematically searched for studies that investigated the correlation between the Silva classification system and the oncology prognosis or pathological features of endocervical adenocarcinoma, published in the period from January 2013 to March 2024.
Results: A total of 19 eligible studies including 3122 cases were included in this systematic review and meta-analysis.
Background And Aims: Whole grain consumption is widely recognized as a vital component of a balanced diet. Dietary fiber has been well-documented to play a crucial role in these health benefits attributed to whole grain intake. However, population-based evidence directly linking whole grain consumption to anti-inflammatory effects, especially in the context of immune-mediated inflammation, remains limited.

- Self-expanding (SE) and balloon-expandable (BE) transcatheter heart valves (THVs) are being studied for their performance in valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), with a focus on clinical outcomes from 315 patients over a decade.
- Results showed that patients with SE THVs experienced lower aortic valve gradients both at 30 days and 1 year post-procedure compared to those with BE THVs, indicating better valve performance.
- Both types of valves showed similar survival rates and mortality, but BE THVs had a higher incidence of severe prosthesis-patient mismatch, suggesting potential differences in long-term outcomes that need further research.
Risk factors and operative risk of large vessel occlusion and stroke during cardiac surgery.
J Stroke Cerebrovasc Dis
November 2024
Objective: Perioperative Large Vessel Occlusions (LVOs) occurring during and following surgery are of immense clinical importance. As such, we aim to present risk factors and test if the Society of Thoracic Surgery (STS) mortality and stroke risk scores can be used to assess operative risk.
Methods: Using data containing 7 index cardiac operations at a single tertiary referral center from 2010 to 2022, logistic and multivariate regression analysis was performed to identify factors that correlate to higher operative LVO and stroke rate.
Patients with small aortic annuli (SAAs) are predominantly women. We sought to compare gender-based and propensity-matched outcomes of index transcatheter aortic valve replacement (TAVR) in patients with SAAs. In this retrospective institutional analysis (2012 to 2023), primary stratification was by gender.

- The study compares outcomes of bioprosthetic versus mechanical valves in older patients who had surgical aortic valve replacement (SAVR), using data from 1,847 patients over a follow-up period of 6.2 years.
- It found no significant differences in early survival between valve types across age groups, but younger patients (<65 years) with bioprosthetic valves faced higher reintervention rates compared to those with mechanical valves.
- The study indicates that bioprosthetic valves are associated with a significantly higher risk of needing repeat aortic valve surgery in younger patients, highlighting the need for better validation of valve type recommendations for different age groups.
Article Synopsis
- The study aimed to evaluate the outcomes of total arch replacement (TAR) using hypothermic circulatory arrest and bilateral antegrade cerebral perfusion (bACP) for patients with acute Type A aortic dissection (ATAAD) employing an "arch first" approach.
- Researchers conducted an observational study over 11 years, analyzing data from 215 patients undergoing TAR with bACP, focusing on short-term and long-term postoperative results.
- Findings showed a 16.3% operative mortality rate, a 1-year survival rate of 77.1%, and a 5-year survival rate of 67.1%, indicating that the "arch first" approach provides acceptable short-term outcomes and reasonable long-term durability for ATA
A chip-scale chaotic laser system with optoelectronic delayed feedback is proposed and analyzed by numerical simulation. This chip eliminates the need for bulky delay components such as long optical fibers, free propagation and external cavities, relying solely on internal devices and waveguides to achieve feedback delay. This approach simplifies integration, maintaining a compact chip size.

Methods: In this meta-analysis we analyzed studies published in PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and Clinical Trials.
Article Synopsis
- Aortic arch surgeries with hypothermic circulatory arrest (HCA) are riskier than standard cardiac surgeries, prompting a need to validate the ARCH score for mortality risk.
- The study analyzed 760 patients from 2014 to 2023, finding that while in-hospital mortality was 8.4%, the ARCH score had low effectiveness in predicting this outcome (C-statistic of 0.62).
- Despite its low predictive ability, the ARCH score demonstrated excellent calibration, indicating it can effectively estimate mortality risk when applied properly.
This study aimed to investigate the feasibility, indications, and benefits of transvaginal natural orifice transluminal endoscopic surgery (v-NOTES) hysterectomy for nonmalignant gynecological diseases. The clinical data, including the baseline information and surgical conditions of 81 patients who underwent v-NOTES hysterectomy for nonmalignant gynecological diseases in a tertiary university hospital from October 2018 to August 2022, were retrospectively analyzed and compared with the total laparoscopic hysterectomy group (200 cases) and the transumbilical laparoendoscopic Single Site Surgery group (150 cases). In comparison with the other 2 groups, the highest proportion of patients in the v-NOTES group had cervical intraepithelial neoplasia.
