Visceral Adipose Tissue Percentage Compared to Body Mass Index as Better Indicator of Surgical Outcomes in Women With Obesity and Endometrial Cancer.

STUDY OBJECTIVE: To assess the impact visceral adipose tissue percentage (VAT%) on surgical outcomes during minimally invasive surgery in obese women with endometrial cancer. DESIGN: Retrospective observational cohort study. SETTING: Mie University Hospital, Japan. PATIENTS: Of the 73 women (body mass index [BMI] >30 kg/m2) with obesity and primary endometrial cancer, 52 underwent robotic surgery, while 21 underwent laparoscopic surgery between April 2014 and December 2022. INTERVENTIONS: We investigated the correlation between surgical outcomes (operative time and blood loss) and obesity (BMI and visceral adipose tissue percentage [VAT%]). MEASUREMENTS AND MAIN RESULTS: Abdominal fat-related parameters were measured at the level of the umbilicus using preoperative computed tomography. A weak negative correlation was found between BMI and VAT% (CC = -0.313, p = .001). Multivariate analysis showed that VAT% had a stronger correlation to total and practical operative time than BMI (ß = 0.338 vs 0.267, ß = 0.311 vs 0.209, respectively) and was an independent predictor of blood loss. VAT% was an independent predictive marker prolonged for operative time and increased blood loss during lymphadenectomy. CONCLUSION: VAT% could be an indicator of surgical outcomes for patients with obesity and endometrial cancer.

Comparison of surgical outcomes between robot-assisted laparoscopic hysterectomy and conventional total laparoscopic hysterectomy in gynecologic benign disease: a single-center cohort study.

We compared the surgical outcomes of robot-assisted laparoscopic hysterectomy (RAH) and total laparoscopic hysterectomy (TLH). This single-center cohort study compared 139 RAH cases from January, 2017 to September, 2021 and 291 TLH cases between January, 2015 and December, 2020. We retrospectively evaluated surgical outcomes, including total operative time (defined as the time from port wound incision to port wound closure), net operative time (defined as the time from the start of pneumoperitoneum to the end of pneumoperitoneum), estimated blood loss, weight of excised uterus (±adnexa), and overall complications, and the relationship between surgeon experience and operative time, net operative time, and blood loss in RAH and TLH. There was no significant difference in the total operative time between the two groups. Regardless of surgeon experience, the net operative time was significantly shorter in the RAH group than in the TLH group (p <0.001) and the estimated blood loss was significantly lower in RAH cases than in TLH cases (p = 0.01). The net operative time per uterine weight was shorter in the TLH group than that in the RAH group; however, there was no significant difference. RAH resulted in statistically better surgical outcomes in terms of net operative time and blood loss, regardless of surgeon experience. However, net operative time and blood loss also seem to be significantly affected by uterus weight. Large trials are imperative to determine the more effective surgical approach between RAH and TLH for different patient subsets.

Fetal heart rate evolution and brain imaging findings in preterm infants with severe cerebral palsy.

BACKGROUND: Cerebral palsy is more common among preterm infants than among full-term infants. Although there is still no clear evidence that fetal heart rate monitoring effectively reduces cerebral palsy incidence, it is helpful to estimate the timing of brain injury leading to cerebral palsy and the causal relationship with delivery based on the fetal heart rate evolution patterns. Understanding the relationship between the timing and the type of brain injury can help to identify preventive measures in obstetrical care. OBJECTIVE: This study aimed to examine the relationship between the timing of insults and the type of brain injury in preterm infants with severe cerebral palsy. STUDY DESIGN: This longitudinal study was based on a nationwide database for cerebral palsy. The data of infants with severe cerebral palsy (equivalent to levels 3-5 of the Gross Motor Function Classification System-Expanded and Revised), born between 2009 and 2014 at 28 to 33 weeks of gestation, were included. The intrapartum fetal heart rate evolution patterns were evaluated by 3 obstetricians blinded to clinical information other than gestational age at birth, and these were categorized after agreement by at least 2 of the 3 reviewers into (1) continuous bradycardia, (2) persistently nonreassuring (prenatal onset), (3) reassuring-prolonged deceleration, (4) Hon's pattern (intrapartum onset), (5) persistently reassuring (pre- or postnatal onset), and (6) unclassified. Infant brain magnetic resonance imaging findings at term-equivalent age were assessed by a pediatric neurologist blinded to the background details, except for gestational age at birth and corrected age at image acquisition, and these were categorized as (1) basal ganglia-thalamus, (2) white matter, (3) watershed cortex or subcortex, (4) stroke, (5) normal, and (6) unclassified based on the predominant site involved. The risk factors for the basal ganglia-thalamus group were compared with those of the combined white matter and watershed injuries group. RESULTS: Among 1593 infants with severe cerebral palsy, 231 were born at 28 to 33 weeks of gestation, and 140 met the eligibility criteria. Fetal heart rate evolution patterns were categorized as bradycardia (17% [24]); persistently nonreassuring (40% [56]); reassuring-prolonged deceleration (7% [10]); reassuring-Hon (6% [8]); persistently reassuring (7% [10]); and unclassified (23% [32]). Cerebral palsy was presumed to have an antenatal onset in 57% of infants and to have been caused by intrapartum insult in 13% of infants. Magnetic resonance imaging showed that 34% (n=48) of infants developed basal ganglia-thalamus-dominant brain injury. Of the remaining 92 infants, 43% (60) showed white matter injuries, 1% (1) showed watershed injuries, 4% (5) showed stroke, 1% (1) had normal findings, and 18% (25) had unclassified findings. Infants with continuous bradycardia (adjusted odds ratio, 1033.06; 95% confidence interval, 15.49-68,879.92) and persistently nonreassuring fetal heart rate patterns (61.20; 2.09-1793.12) had a significantly increased risk for basal ganglia-thalamus injury. CONCLUSION: Severe cerebral palsy was presumed to have an antenatal onset in 57% of infants and to have been caused by intrapartum insult in only 13% of infants born at 28 to 33 weeks of gestation. Although the white matter-watershed injury was predominant in the study populations, severe acute hypoxia-ischemia may be an important prenatal etiology of severe cerebral palsy in preterm infants.

Efficacy of minodronic acid for the prevention of osteoporosis in premenopausal women with gynaecologic disease who undergo bilateral oophorectomy: a single-centre, non-randomised controlled, experimental study.

We evaluated the efficacy of minodronic acid for osteoporosis prevention after bilateral oophorectomy for gynaecologic disease in premenopausal women. Bone mineral density (BMD) and young adult mean (YAM) data from the lumbar vertebrae and femur and bone alkaline phosphatase (BAP)/tartrate-resistant acid phosphatase 5 b (TRACP 5 b) data were obtained for 101 patients. The primary endpoint was the efficacy of minodronic acid for osteoporosis prevention. Fifty-five and 31 patients were assigned to medication and no medication groups, respectively. The decrease in BMD and YAM and the increase in BAP/TRACP-5b were significantly more suppressed in the medication group. There were no significant between-group differences in age at oophorectomy, cancer type, body mass index (BMI), and adjuvant therapy. There were no adverse events due to minodronic acid. Minodronic acid may prevent osteoporosis after oophorectomy in premenopausal women with gynaecologic disease, independent of age at oophorectomy, cancer type, BMI, or adjuvant therapy. Impact statementWhat is already known on this subject? Although the current strategy for osteoporosis prevention after premenopausal bilateral oophorectomy (b-OVX) is hormone therapy (HT), there is no consensus on the treatment duration or adverse events.What do the results of this study add? Therefore, we planned a prospective study to evaluate the efficacy of prophylactic treatment for osteoporosis after b-OVX in premenopausal women with gynaecologic disease using minodronic acid, an oral bisphosphonate, which have a strong evidence of the treatment for osteoporosis. The result showed minodronic acid significantly suppressed the decrease in bone mineral density (BMD) and young adult mean (YAM) and the increase in bone alkaline phosphatase (BAP)/tartrate-resistant acid phosphatase 5b (TRACP 5b). Minodronic acid may prevent osteoporosis after oophorectomy in premenopausal women with gynaecologic disease, independent of age at oophorectomy, cancer type, BMI, or adjuvant therapy.What are the implications of these findings for clinical practice and/or further research? Minodronic acid treatment for osteoporosis prevention after premenopausal b-OVX may be effective as a therapeutic agent after the cessation of HT, or alternative for patients who are contraindicated for HT in breast cancer and thrombosis and should be administered with caution with a history of uterine or ovarian cancer.

Does Vaginal Cuff Creation and Avoidance of a Uterine Manipulator Improve the Prognosis of Total Laparoscopic Radical Hysterectomy for Early Cervical Cancer? A Retrospective Multicenter Study.

Our goal was to compare the treatment outcomes of open-abdominal radical hysterectomy (O-RH) and total laparoscopic hysterectomy (TLRH) with vaginal cuff creation and without using a uterine manipulator in stage IB1-B2 (tumor size < 4 cm) cervical cancer cases. In this retrospective multicenter analysis, 94 cervical cancer stage IB1-B2 patients who underwent O-RH or TLRH in six hospitals in Japan between September 2016 and July 2020 were included; 36 patients underwent TLRH. Propensity score matching was performed because the tumor diameter was large, and positive cases of lymph node metastases were included in the O-RH group due to selection bias. The primary endpoint was progression-free survival (PFS) and recurrence sites of TLRH and O-RH. PFS and OS (overall survival) were not significant in both the TLRH (n = 27) and O-RH (n = 27) groups; none required conversion to laparotomy. The maximum tumor size was <2 and ≥2 cm in 12 (44.4%) and 15 (55.6%) patients, respectively, in both groups. Reportedly, the TLRH group had lesser bleeding than the O-RH group (p < 0.001). Median follow-up was 33.5 (2−65) and 41.5 (6−75) months in the TLRH and O-RH groups, respectively. PFS and OS were not significantly different between the two groups (TLRH: 92.6%, O-RH: 92.6%; log-rank p = 0.985 and 97.2%, 100%; p = 0.317, respectively). The prognosis of early cervical cancer was not significantly different between TLRH and O-RH. Tumor spillage was prevented by creating a vaginal cuff and avoiding the use of a uterine manipulator. Therefore, TLRH might be considered efficient.

Correlation between fetal heart rate evolution patterns and magnetic resonance imaging findings in severe cerebral palsy: A longitudinal study.

OBJECTIVE: To investigate the association between hypoxic-ischaemic insult timing and brain injury type in infants with severe cerebral palsy (CP). DESIGN: Longitudinal study. SETTING: Database of the Recurrence Prevention Committee, Japan Obstetric Compensation System for Cerebral Palsy. SAMPLE: Infants with severe CP born at ≥34 weeks of gestation. METHODS: The intrapartum fetal heart rate (FHR) strips were categorised as continuous bradycardia; persistently non-reassuring (NR-NR); reassuring-prolonged deceleration (R-PD); Hon's pattern (R-Hon); persistently reassuring (R-R); and unclassified. The brain magnetic resonance imaging (MRI) scans were categorised based on the predominant site involved: basal ganglia-thalamus (BGT); white matter (WM); watershed (WS); stroke; normal; and unclassified. MAIN OUTCOME MEASURES: Manifestations of the brain MRI types and the association between FHR evolution pattern and MRI type were analysed. RESULTS: Among 672 eligible infants, 76% had BGT-dominant injury, 5.4% WM, 1.2% WS, 1.6% stroke, 1.9% normal, and 14% unclassified. Placental abruption and small-for-gestational age were associated with an increased (adjusted odds ratio [aOR] 8.02) and decreased (aOR 0.38) risk of BGT injury, respectively. The majority of infants had BGT injury in most FHR groups (bradycardia, 97%; NR-NR, 75%; R-PD, 90%; R-Hon, 76%; and R-R, 45%). The risk profiles in case of BGT in the NR-NR group were similar to those in the R-PD and R-Hon groups. CONCLUSION: BGT-dominant brain damage accounted for three-fourths of the cases of CP in term or near-term infants, even in prenatal onset cases. Hypoxic-ischaemic insult has a major impact on CP development during the antenatal period. TWEETABLE ABSTRACT: Basal ganglia-thalamus injury constitutes 76% of severe cerebral palsy cases, predominant even in antenatal-onset cases.

Fetal heart rate pattern in term or near-term cerebral palsy: a nationwide cohort study.

BACKGROUND: It is crucial to interpret fetal heart rate patterns with a focus on the pattern evolution during labor to estimate the relationship between cerebral palsy and delivery. However, nationwide data are not available. OBJECTIVE: The aim of our study was to demonstrate the features of fetal heart rate pattern evolution and estimate the timing of fetal brain injury during labor in cerebral palsy cases. STUDY DESIGN: In this longitudinal study, 1069 consecutive intrapartum fetal heart rate strips from infants with severe cerebral palsy at or beyond 34 weeks of gestation, were analyzed. They were categorized as follows: (1) continuous bradycardia (Bradycardia), (2) persistently nonreassuring, (3) reassuring-prolonged deceleration, (4) Hon's pattern, and (5) persistently reassuring. The clinical factors underlying cerebral palsy in each group were assessed. RESULTS: Hypoxic brain injury during labor (those in the reassuring-prolonged deceleration and Hon's pattern groups) accounted for 31.5% of severe cerebral palsy cases and at least 30% of those developed during the antenatal period. Of the 1069 cases, 7.86% were classified as continuous bradycardia (n=84), 21.7% as persistently nonreassuring (n=232), 15.6% as reassuring-prolonged deceleration (n=167), 15.9% as Hon's pattern (n=170), 19.8% as persistently reassuring (n=212), and 19.1% were unclassified (n=204). The overall interobserver agreement was moderate (kappa 0.59). Placental abruption was the most common cause (31.9%) of cerebral palsy, accounting for almost 90% of cases in the continuous bradycardia group (64 of 73). Among the cases in the Hon's pattern group (n=67), umbilical cord abnormalities were the most common clinical factor for cerebral palsy development (29.9%), followed by placental abruption (20.9%), and inappropriate operative vaginal delivery (13.4%). CONCLUSION: Intrapartum hypoxic brain injury accounted for approximately 30% of severe cerebral palsy cases, whereas a substantial proportion of the cases were suspected to have either a prenatal or postnatal onset. Up to 16% of cerebral palsy cases may be preventable by placing a greater focus on the earlier changes seen in the Hon's fetal heart rate progression.

Retrospective study of pregnancies in women with Thr331Ala fibrinogen polymorphisms.

Background: We aimed to retrospectively review data of pregnant women with the α-fibrinogen Thr331Ala polymorphism; evaluate the relationship between this polymorphism and spontaneous abortion (SA), fetal growth restriction (FGR), and intrauterine fetal death (IUFD); and assess the effects of aspirin and/or heparin.Materials and methods: We examined the outcomes of 29 pregnancies (nine women) in women with the α-fibrinogen Thr331Ala polymorphism. Of these, 16 were untreated, whereas 13 were treated with heparin and/or aspirin.Results: The live birth rate was significantly higher in the treated group than in the nontreated group (69.2 versus 6.2%; p = .0004). In addition, the prophylactic use of a low dose of aspirin and/or heparin during early pregnancy in women with Thr331Ala may be an effective method for reducing fetal loss in these patients.Conclusions: This polymorphism interacts with pregnancy to result in poor obstetrical outcomes, but these effects can be mitigated with medical intervention. This study is the first to report outcomes of pregnancies complicated by the Thr331Ala polymorphism, which we believe may cause thrombophilia, SA, and IUFD. This study highlights the need for further research on this polymorphism in pregnancy.

A Case of Type I Sirenomelia Complicated by Severe Oligohydramnios in the First Trimester.

Sirenomelia is a very rare congenital anomaly. Type I is the mildest type, and the long bone structures are all normally present with only soft tissue fusion. We experienced a case of type I sirenomelia complicated by severe oligohydramnios. Because of severe oligohydramnios, ultrasonographic images were not very clear. The associated findings with sirenomelia (single umbilical artery and bilateral renal agenesis) were helpful for the prenatal diagnosis of this disease. Detailed sonographic examination of the fetus was thought to be necessary for the accurate prenatal diagnosis of sirenomelia.
