目的:探讨体外受精/卵胞质内单精子注射-胚胎移植(IVF/ICSI-ET)对不同体质指数(BMI)女性患者临床结局的影响。方法:回顾性分析2020年1月-2023年3月本中心生殖中心接受IVF/ICSI-ET治疗的女性患者临床资料,根据女性BMI分为低体质量组(BMI<18.5kg/m^(2))、正常体质量组(18.5kg/m^(2)≤BMI<24.9kg/m^(2))、超重组(BMI≥24.9kg/m^(2)),比较3组行IVF/ICSI-ET助孕临床结局,logistic回归分析影响IVF/ICSI-ET临床妊娠率和活产率相关影响因素。结果:3组不孕年限、BMI、Gn用量、不孕原因存在差异(P<0.05)。低体质量组(36%,31/86)、正常体质量组(39.8%,276/693)、超重组(43.2%,108/250)临床妊娠率无差异,流产率(16.1%,5/31)、(10.1%,28/276)、(38.0%,41/108)有差异(P<0.05),活产率(30.2%,26/86)、(34.8%,241/693)、(26.4%,66/250)有差异(P<0.05)。logistic多因素回归分析显示,BMI超重和Gn用量多是影响辅助生殖后临床妊娠的因素,Gn用量多是影响辅助生殖后妊娠活产的因素(均P<0.05)。结论:备孕女性行IVF治疗前,使BMI达到或接近正常,以改善IVF/ICSI-ET助孕的妊娠结局。

基于数值延拓的日月综合借力DRO入轨策略

远距离逆行轨道(DRO)是地月空间中的一类周期轨道,这类轨道具有长期稳定、入轨能量低的特点,可作为未来载人月球和载人火星任务的中转站。对于地球至DRO的两脉冲入轨任务,采用日月综合借力(即同时使用弱稳定边界(WSB)和月球借力(LGA))可以最大化入轨质量,但是这类轨道对初值非常敏感。使用日月综合借力拓展DRO入轨脉冲包络,改进构造方法和提供解析梯度大幅提高多步打靶收敛率,提出2层伪弧长延拓方法进一步降低任务总脉冲。数值仿真采用共振比为2∶1的DRO,脉冲最低解采用“LGA+WSB+2LGA”的飞行模式,飞行时间为123天,近地轨道发射脉冲为3.125 km/s,DRO入轨脉冲仅为19.7 m/s。

The impact of male overweight on semen quality and outcome of assisted reproduction

It is well-documented that male overweight and obesity causes endocrine disorders that might diminish the male reproductive capacity; however, reports have been conflicting regarding the influence of male body mass index （BMI） on semen quality and the outcome of assisted reproductive technology （ART）. The aim of this study was to investigate whether increased male BMI affects sperm quality and the outcome of assisted reproduction in couples with an overweight or obese man and a non-obese partner. Data was prospectively collected from 612 infertile couples undergoing ART at a Danish fertility center. Self-reported information on paternal height and weight were recorded and BMI was calculated. The men were divided into four BMI categories： underweight BMI 〈 20 kgm^-2, normal BMI 20-24.9 kg m^-2, overweight BMI 25-29.9 kgm^-2 and obese BMI 〉 30 kgm^-2. Conventional semen analysis was performed according to the World Health Organization guideline and sperm DNA integrity was analyzed by the Sperm Chromatin Structure Assay （SCSA）. No statistically significant effect of male BMI was seen on conventional semen parameters （sperm concentration, total sperm count, seminal volume and motility） or on SCSA-results. Furthermore, the outcome of ART regarding fertilization rate, number of good quality embryos （GQE）, implantation and pregnancy outcome was not influenced by the increasing male BMIo

The Impact of Body Mass Index on Assisted Reproductive Treatments

Multiparity amongst women with a body mass index (BMI) ≥ 30 Kg/m2 is a common occurrence despite there being a known clear association with a decline in fecundity in women who are overweight or obese. These women, also pose further concerns, as they are at increased risk of antenatal complications such as preeclampsia and gestational diabetes. Over the years, a number of different modalities of fertility treatments have been tried and tested in this cohort of women to find the optimal treatment to improve their reproductive capacity. There has been an exponential increase in knowledge and understanding towards managing patients with a raised BMI, particularly through assisted reproductive treatments. Although the efficacies of various forms of fertility treatments have been shown to be affected by a rise in BMI, there is yet to be a definitive understanding as to the optimal management of these patients. The literature supports weight loss alone as an effective intervention in improving the reproductive capacity of women with a raised BMI with unexplained infertility. Furthermore, if live birth rate is taken as the desired outcome measure, then ovarian drilling and in vitro fertilisation (IVF) treatment have been shown to yield the best results in overweight and obese patients when comparisons are drawn to other interventions such as natural conception and treatment with clomiphene citrate.

The relationship between maternal body fat and pre-implantation embryonic weight: Implications for survival and long-term development in an assisted reproductive environment

There can be little argument that embryo quality is one of the most critical factors in the success of assisted reproductive techniques. Yet the current methods of grading embryos are subjective at best. While a number of different groups have described more qualitative means of assessing embryo quality, the current standard remains morphology. Morphology has proven a good standard, but it does not allow for the detection of chromosomal abnormalities nor can it assess the biochemical status of the embryo prior to transfer. This laboratory recently described a method to estimate embryo weight and suggested weight might be a good indicator of biochemical status. The objective of the present study was to determine the relationship between maternal body composition and embryo weight and determine the influence maternal chemistry had on embryo development. The data continue to suggest that maternal body composition, especially body fat, influences the chemical nature of the embryo and may play a critical role in long-term survival.

Development and Proof-of-Concept Study of a Novel Intraoperative Surgical Planning Tool for Robotic Arm-Assisted Total Knee Arthroplasty

Background: Intraoperative surgical planning tools (ISPTs) used in current-generation robotic arm-assisted total knee arthroplasty (RTKA) systems (such as Navio® and MAKO®) involve employment of postoperative passive joint balancing. This results in improper ligament tension, which may negatively impact joint stability, which, in turn, may adversely affect patient function after TKA. Methods: A simulation-enhanced ISPT (SEISPT) that provides insights relating to postoperative active joint mechanics was developed. This involved four steps: 1) validation of a multi-body musculoskeletal model;2) optimization of the validated model;3) use of the validated and optimized model to derive knee performance equations (KPEs), which are equations that relate implant component characteristics to implant component biomechanical responses;and 4) optimization of the KPEs with respect to these responses. In a proof-of-concept study, KPEs that involved two com- ponent biomechanical responses that have been shown to strongly correlate with poor proprioception (a common patient complaint post-TKA) were used to calculate optimal positions and orientations of the femoral and tibial components in the TKA design implanted in one subject (as reported in a publicly-available dataset). Results: The differences between the calculated implant positions and orientations and the corresponding achieved values for the implant components in the subject were not similar to component position and orientation errors reported in biomechanical literature studies involving Navio® and MAKO®. Also, we indicate how SEISPT could be incorporated into the surgical workflow of Navio® with minimal disruption and increase in cost. Conclusion: SEISPT is a plausible alternative to current-gen- eration ISPTs.

Effects of female body mass index on embryo development and ART outcomes

Objective:To investigate the effects of female body mass index on embryo development and assisted reproductive technology outcomes,aiming to provide better treatment for patients with different body mass index and provide reference for clinical treatment.Methods:The study retrospectively collected data of 3783 patients who received their first fresh embryo transfer and were ovulated by a long protocol at the Reproductive Medicine Center of the First Affiliated Hospital of Hainan Medical University from January 2015 to October 2021.Patients were divided into four groups based on body mass index(BMI):low weight group,normal weight group,overweight group and obese group.The normal weight group was used as a control to compare the basic information,assisted reproductive technology process,embryo development and assisted reproductive technology outcomes between different groups.Results:Analyzing patients'basic information,we found that the duration of infertility was significantly longer in obese women(P=0.007).Basal hormone levels in the overweight and obese groups were lower than those in the normal group(P<0.05).Basal Follicle-stimulating hormone(FSH),basal Luteinizing hormone(LH),basal Estradiol(E2),basal Progesterone(P),and anti-Mullerian hormone(AMH)in the obese group were lower than the normal weight group(P<0.05),and the number of antral follicle counting(AFC)was reduced in the obese group(P=0.011).The overweight group only showed a decrease in E2 and P levels(P<0.05).During the ART,there was a significant difference in Gonadotropin(Gn)dosage among the four groups,with the obese group was the most,followed by the overweight group,and the low weight group was the least(P<0.001).Gn days were increased in the obese group(P<0.001).LH,E2,and P on trigger day were all lower in the overweight and obese groups than in the normal weight group(P<0.05).Comparing the embryo development process,we found that the blastocysts of the obese group showed delayed development at the stages of pronuclei disappearance,four-cell and blastocyst formation(P<0.05).The ART outcomes were worse in the obese group,the clinical pregnancy rate(P=0.044)and live birth rate(P=0.036)were reduced in the obese group.After logistic regression,obesity was found to be a risk factor for clinical pregnancy(OR=0.683,95%CI:0.479-0.973,P=0.035)and live birth(OR=0.662,95%CI:0.459-0.954,P=0.027).Female age was a risk factor for biochemical pregnancy,clinical pregnancy and live birth(P<0.05).Conclusion:Female obesity prolongs the duration of infertility,causes endocrine disorders,increases Gn dosage and days,and leads to poorer assisted reproductive technology outcomes.Female obesity delays the blastocyst development process and presents as a risk factor for clinical pregnancy and live birth.
