RESUMO

Background and Objectives: Vasa previa (VP) is a significant perinatal complication that can have serious consequences for the fetus/neonate. Velamentous cord insertion (VCI) is a crucial finding in prenatal placental morphology surveillance as it is indicative of comorbid VP. Assisted reproductive technology (ART) has been identified as a risk factor for VCI, so identifying risk factors for VCI in ART could improve VP recognition. This study aims to evaluate the displacement of umbilical cord insertion (CI) from the placental center and to examine the relationship between the modes of conception. Materials and Methods: We conducted a retrospective study at the Obstetrics Department of Osaka Metropolitan University Hospital in Japan between May 2020 and June 2022. The study included a total of 1102 patients who delivered after 22 weeks of gestation. They were divided into three groups: spontaneous pregnancy, conventional in vitro fertilization (cIVF), and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). We recorded patient background information, perinatal complications, perinatal outcomes, and a numerical "displacement score", indicating the degree of separation between umbilical CI and the placental center. Results: The displacement score was significantly higher in the cIVF and IVF/ICSI groups compared with the spontaneous conception group. Additionally, the IVF/ICSI group showed a significantly higher displacement score than the cIVF group. Conclusions: Our study provides the first evidence that the methods of ART can affect the location of umbilical CI on the placental surface. Furthermore, we found that IVF/ICSI may contribute to greater displacement of CI from the placental center.

RESUMO

Perineal hernia is an infrequent complication of abdominoperineal resection (APR) and, currently, there is no consensus as to the optimal operative technique. Surgical repair can be achieved by either cerclage or the use of mesh or autologous tissue, and it has been reported that the recurrence rate after repair using autologous tissue is 33%. We present two post-APR cases of severe perineal hernia with pelvic organ prolapse (POP) which did not improve after repair using mesh. We regenerated the pelvic floor using a vertical rectus abdominis myocutaneous (VRAM) flap and performed a concomitant sacrocolpopexy to fix the POP. Drooping of the perineum and pelvic floor was greatly improved, and the patients have not experienced any recurrence for 6 years. This dual procedure has not been previously mentioned in the literature, and we consider this the first report of its kind.

RESUMO

PURPOSE: The latest treatments do not sufficiently prevent miscarriage and fetal growth restriction (FGR) in pregnant women. Here, we assessed the effects of a human protein, CTRP6, that specifically inhibits the activation of the alternative complement pathway on miscarriage, fetal and placental development. METHODS: Pregnant CBA/J mice mated with DBA/2 male mice as a model of spontaneous abortion and FGR were randomly divided into the control and CTRP6 groups. In the CTRP6 group, the mice were intravenously administered CTRP6 on days 4.5 and 6.5 post-conception (dpc). The abortion rate and fetal and placental weights on 14.5 dpc were examined. Remodeling of the spiral artery was also assessed. RESULTS: The abortion rate in the CTRP6 group (13%) was reduced compared to the control group (21%), but there was no statistical difference. The placental and fetal weights in the CTRP6 group were also heavier than those in the control (P < 0.05). Moreover, the thickness of the blood vessel wall in the CTRP6 group was significantly thinner than that in the control (P < 0.05) and comparable to that in the non-abortion model (CBA/J x BALB). The ratio of the inner-per-the-outer diameter of the spiral artery increased more in the CTRP6 group than that in the control (P < 0.05). As well, the Th1/Th2 cytokine ratio was significantly reduced by CTRP6 treatment. CONCLUSIONS: Taken together, the supplementation with a protein that regulates the alternative complement pathway in vivo improves FGR and promotes spiral artery remodeling in a mouse model of miscarriage and FGR.

RESUMO

Female pattern hair loss (FPHL), a type of hair disease common in pre- and postmenopausal women, is characterized by thinning of hair to O-type, mainly at the crown. Although a mouse model of this disease has recently been established, its details are still unknown, and thus, warrants further analysis. In this study, 3 week-old and 7- to 8 week-old C57BL/6 female mice were divided into two groups: one group underwent ovariectomy (OVX), while the other underwent sham surgery. In the 3 week-old mice, the dorsal skin was collected at seven weeks of age, while in the 7- to 8 week-old mice, it was collected at 12 and 24 weeks of age. In the former group, both the pore size of the hair follicles (HFs) and diameter of the hair shaft of telogen HFs decreased upon OVX; while in the latter group, these factors increased significantly. Notably, the thickness of the dermis and subcutis increased significantly in the OVX group. It needs to be further elucidated whether OVX mouse could serve as an ideal mouse model for FPHL, but our results upon evaluation of skin thickness indicate that it could be used to establish a novel treatment for non-hair-related diseases, such as post-menopause-related skin condition.

RESUMO

Background and Objectives: There are no reports showing the hematopoietic effect of TJ-108 on pregnant women. The aim of this study was to investigate the effect of TJ-108 on the hemoglobin and hematocrit levels, and white blood cell and platelet counts of pregnant women complicated with placenta previa who were managed with autologous blood storage for cesarean section. Materials and Methods: We studied two groups of patients who were complicated with placenta previa and who underwent cesarean delivery. Group A consisted of women who were treated with oral iron medication (100 mg/day), and Group B consisted of women who were treated with TJ-108 at a dose of 9.0 g per day, in addition to oral iron medication, from the first day of blood storage until the day before cesarean delivery. To evaluate the effect of TJ-108, the patients' red blood cell (RBC); Hb; hematocrit (Ht); white blood cell (WBC); and platelet count (PLT) levels were measured 7 days after storage and at postoperative days (POD) 1 and 5. Results: The study included 65 individuals, 38 in group A and 27 in group B. At the initial storage, a 0.2 g/dL reduction in Hb levels was observed, as compared to the initial Hb levels, in the TJ-108 treated patients, whereas a 0.6 g/dL reduction in Hb levels was observed in the non-TJ-108 treated group. On the other hand, regarding the second and subsequent storages, no significant difference was found in the decrease in the Hb levels of both groups. Conclusions: This study is the first report showing the effect of TJ-108 on improving anemia in pregnant women, presumably by its boosting effect on myelohematopoiesis. Therefore, the combined administration of both iron and TJ-108 is effective as a strategy for pregnant women at a high risk of PPH due to complications such as placenta previa.

RESUMO

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) in women is associated with deficiency of elastic fibers, and fibulin-5 is known to be a critical protein in the synthesis of elastin. The purpose of this study is to investigate the related pathway for the synthesis of elastin via fibulin-5 using fibulin-5 knockout mice. METHODS: Fibulin-5 knockout mice were generated using the CRISPR/Cas9 system, and vaginal dilatation was used to mimic vaginal delivery. We divided the mice into three groups: Fbln5+/+ mice immediately after dilatation (Fbln5+/+ day0), Fbln5+/+ mice 3 days after dilatation (Fbln5+/+ day3) and Fbln5-/- mice 3 days after dilatation (Fbln5-/- day3). Proteins related to elastogenesis in the vaginal wall were measured by liquid chromatography mass spectrometry (LC-MS/MS) analysis, and differences in the expression of these proteins between the Fbln5-/- mice and the Fbln5+/+ mice were analyzed using western blotting. RESULTS: In the LC-MS/MS analysis, protein tyrosine kinase 7 (PTK7) was not detected in the Fbln5-/- day3 group, although the expression increased by > 1.5 times between the Fbln5+/+ day0 and day3 groups. PTK7 and ß-catenin are known to act in the Wnt/ß-catenin pathway, and both were upregulated after dilatation in the Fbln5+/+ mice, though not in the Fbln5-/- mice. CONCLUSION: Our findings suggest that these proteins are involved in elastogenesis via fibulin-5, and the impairment of these proteins might be the underlying cause of POP manifestation.

RESUMO

BACKGROUND: The aims of this study were to evaluate the time intervals of flow velocity waveforms (FVW) of ductus venosus (DV) and cardiac cycles, as well as the pulsatility index of DV-FVW (DV-PI), in correlation with umbilical artery (UA) pH at birth in fetal growth restriction (FGR) complicated with placental insufficiency. METHODS: Data were retrospectively retrieved from pregnancies complicated by FGR. FGR was defined as an estimated fetal weight below - 2.0 S.D. with an elevated UA-PI. Time interval assessments of DV-FVW were as follows: the duration of systolic wave was divided by the duration of diastolic wave and defined as DV-S/D. We also measured the following time intervals of ventricular inflow through tricuspid valve (TV) and mitral valve (MV): (iii), from the second peak of ventricular inflow caused by atrial contraction (A-wave) to the opening of atrio-ventricular valves and: (iv), from the opening of atrio-ventricular valves to the peak of A-wave. (iii)/(iv) was expressed as TV-S/D and MV-S/D, for TV and MV, respectively. The time interval data were transformed into z-scores. RESULTS: Thirty-one FGR fetuses were included in this study. Both DV-PI and DV-S/D showed significant correlation with UA-pH (r = - 0.677, p = < 0.001 and r = 0.489, p = 0.005 for DV-PI and z-score of DV-S/D, respectively) and more significances were observed in FGR ≤ 28 + 6 gestational weeks (r = - 0.819, p < 0.001 and r = 0.726, p = 0.005, for DV-PI and z-score of DV-S/D, respectively) than in FGR > 28 + 6 gestational weeks (r = - 0.634, p = 0.007 and r = 0.635, p = 0.020, for DV-PI and z-score of DV-S/D, respectively). On the other hand, TV-S/D and MV-S/D showed no significant correlation with UA-pH, although these z-scores indicated significant decreases compared with normal references. CONCLUSIONS: Time interval analysis of DV-FVW might be a valuable parameter, as well as DV-PI, for the antenatal prediction of fetal acidemia in the management of FGR fetuses.

RESUMO

AIM: Tension-free vaginal mesh (TVM) surgery using synthetic polypropylene (PP) soft mesh had spread rapidly. However, the frequency of mesh-related postoperative complications had increased, and PP was banned in April 2019. In Japan, however, transvaginal surgery using polytetrafluoroethylene (PTFE) mesh had been approved. In this study, we evaluated the clinical outcome and quality of life (QOL) of the postoperative course using PP mesh and PTFE mesh (named "ORIHIME™" ) in a combination surgery for utero-sacral ligament suspension and anterior vaginal support using anterior TVM. METHODS: The vaginal hysterectomy and utero-sacral ligament colpopexy augmented by anterior vaginal mesh implants using PP mesh and PTFE mesh were performed on patients with stage III to IV cystocele and uterine prolapse. The clinical outcome and QOL changes in their postoperative course were evaluated by comparing 15 cases of PP mesh and 13 cases of PTFE mesh. RESULTS: There was no difference between the PP group and PTFE group in characteristics. No mesh-related complications occurred during the follow-up period. With regard to the pelvic organ prolapse quantification (POP-Q) score, no significant difference was found between the two groups. Comparing the postoperative QOL of both groups, the PTFE group had significantly higher values in two domains than PP group (SF-12v2 questionnaire). CONCLUSIONS: We used the world's first PTFE mesh to compare PP mesh with postoperative POP-Q and QOL after the same surgery, with the same operator, and at the same institution. The results showed no significant difference between both mesh materials in the short-term.

RESUMO

OBJECTIVES: To evaluate the safety and efficacy of transvaginal mesh surgery using a polytetrafluoroethylene mesh to treat pelvic organ prolapse. METHODS: This prospective observational study included women undergoing transvaginal mesh surgery for pelvic organ prolapse that used new polytetrafluoroethylene mesh cut into a shape similar to that of Elevate. We evaluated the subjective and objective outcomes at 3 and 12 months, as well as postoperative complication rates. RESULTS: This study included 55 patients. The pelvic organ prolapse quantification scores improved significantly at 3 and 12 months after surgery compared with scores before surgery. In four patients (7.3%), a pelvic examination showed stage 2 objective recurrence without subjective symptoms. Clavien-Dindo grades 2 and 3 perioperative complications were observed in 9.1% and 1.8% of the patients, respectively. Vaginal mesh exposure occurred in one patient (1.8%) at the time of the 3-month follow-up evaluation. The mesh was exposed at the proximal midline of the anterior vaginal wall. CONCLUSIONS: These findings show the safe and effective use of the polytetrafluoroethylene mesh for transvaginal mesh surgery.

RESUMO

The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

RESUMO

OBJECTIVES: To investigate techniques of transvaginal mesh prolapse surgery in Japan, and compare complication rates by surgeons' specialty and experience with transvaginal mesh prolapse surgery. METHODS: We carried out an anonymous questionnaire survey for surgeons attending a national transvaginal mesh prolapse surgery meeting in 2010. The surgeons were asked to state their specialty, practice patterns, transvaginal mesh prolapse surgery techniques and the number of transvaginal mesh prolapse procedures carried out as an operator including the complications that occurred. RESULTS: A total of 118 surgeons (59% of the attendees) responded to the questionnaire. The mean age was 44.0 ± 9.1 years, 54 (46%) were gynecologists and 64 (54%) were urologists. All urologists and 78% of gynecologists carried out anti-incontinence surgery (midurethral sling), whereas more gynecologists (93%) carried out native tissue repair than urologists (73%). Most of both specialties (each 98%) avoided prophylactic anti-incontinence surgery during prolapse surgery. Concomitant hysterectomy during transvaginal mesh prolapse surgery was generally avoided. Surgeons reached a consensus regarding the critical transvaginal mesh prolapse surgery techniques: hydrodissection (98%) and the full-thickness dissection (the "Lychee layer"; 69%). A total of 11 935 Prolift-type transvaginal mesh prolapse procedures were carried out and the following complications were reported: bladder injury (1.6%), rectal injury (0.3%), ureteral injury (0.1%), blood transfusion (0.2%), vaginal exposure (2.8%) and recurrence requiring reoperation (1.1%). Although complications did not differ between specialty, bladder injury, transfusion and vaginal exposure were less prevalent with experienced surgeons (≥50 transvaginal mesh prolapse surgery cases). CONCLUSIONS: Over 10 000 transvaginal mesh prolapse surgery had been carried out in Japan with a relatively low complication rate until 2010. This survey shows that surgeons' experience could lead to a decrease in the amount of transvaginal mesh prolapse surgery complications.

RESUMO

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) is a multifactorial disorder that impairs the quality of life (QoL) of older women in particular. The purpose of this study was to elucidate the pathogenesis of POP by focusing on the extracellular matrix (ECM). METHODS: Patients were classified into two groups-with or without cervical elongation-using the POP quantification system. Specimens were obtained from 29 women with POP during hysterectomy. The expression of fibulin-5, elastin, integrin ß1 (ITGß1), lysyl oxidase-like protein-1 (LOXL1) and collagen in the vagina, uterosacral ligament, and uterine cervix was investigated by quantitative real-time polymerase chain reaction (RT-PCR) and correlation between gene levels and severity of POP examined. The location of proteins was analyzed using immunohistochemical staining and expression of fibulin-5 protein analyzed by Western blotting. RESULTS: Fibulin-5 and elastin were mainly expressed in lamina propria and fibromuscular layers of the vagina and uterosacral ligament. Gene levels of fibulin-5 and ITGß1 in uterosacral ligaments increased with severity of POP in women with cervical elongation, while no correlation was observed in women with a normal cervix. In women with uterine cervical elongation, each ECM-related gene significantly increased with POP staging. Furthermore, fibulin-5 protein also increased in the uterosacral ligament and uterine cervix. CONCLUSIONS: The severity of POP and gene expression of ECM-related proteins were inversely correlated in vaginal tissue in a normal and elongated cervix. These results suggested that the differing progression of the two types of POP have a relationship with ECM-related protein.

RESUMO

We performed a questionnaire-based, retrospective, nationwide survey on perioperative management and antimicrobial prophylaxis for mid-urethral sling surgery for stress urinary incontinence in Japan to realize the clinical practice and risk factors for SSI. Records of women receiving transobturator tape (TOT) and tension-free vaginal tape (TVT) surgeries from 2010 to 2012 were obtained from hospitals belonging to the Japanese Society of Pelvic Organ Prolapse Surgery. The questionnaire addressed hospital volume, perioperative management, and SSI. Risk factors for SSI were investigated by comparing cases with and without SSI. The data from 97 hospitals and a total 1627 TOT and 1045 TVT surgeries were analyzed. Mean case volumes of TOT and TVT surgeries were 7.3 ± 14.9 and 7.1 ± 17.8 cases per year, respectively. Preoperative hair removal, bowel preparation, and urine culture were routinely performed at 44 (45.3%), 31 (32.0%), and 22 (22.7%) hospitals, respectively. First-generation (51.5%) or second-generation (34.0%) cephalosporin was mostly used for antimicrobial prophylaxis. SSI was reported only in 6 patients (0.22%) and none of them developed abscesses. None of the factors we could evaluate from the questionnaire were found to be significantly associated with SSI. SSI after mid-urethral slings rarely occurred in Japan (0.22%) and no parameters about perioperative managements significantly increased SSI. However, further studies with more detail information of each patient and operation are required to confirm their appropriate perioperative managements for mid-urethral slings.

RESUMO

Background: Infants <6 months of age are too young to receive influenza vaccine, despite being at high risk for severe influenza-related complications. Methods: To examine the effectiveness of maternal influenza vaccination in preventing influenza in their infants, we conducted a prospective cohort study of 3441 infants born at participating hospitals before the 2013-2014 influenza season. At the time of recruitment, their mothers completed a questionnaire about influenza vaccination status for the 2013-2014 season. A follow-up survey was conducted after the end of the 2013-2014 season to collect information regarding influenza diagnosis and hospitalization among infants. Results: During the 2013-2014 influenza season, 71 infants (2%) had influenza diagnosed, and 13 infants (0.4%) were hospitalized with influenza. Maternal influenza vaccination (especially prenatal vaccination) decreased the odds of influenza among infants. The effectiveness of prenatal vaccination was 61% (95% confidence interval, 16%-81%), whereas that of postpartum vaccination was 53% (-28%-83%). Although maternal influenza vaccination was also associated with a decreased odds of influenza-related hospitalization among infants, vaccine effectiveness (73%) did not reach statistical significance, owing to the limited number of infants hospitalized because of influenza. Conclusions: The present findings indicated that pregnant women and postpartum women should receive influenza vaccination to protect their infants.

RESUMO

AIMS: We conducted a nationwide survey on perioperative management and antimicrobial prophylaxis of transvaginal mesh surgeries for pelvic organ prolapse in Japan to understand the practice and risk factors for surgical site infection (SSI). METHODS: Health records of women undergoing tension-free vaginal mesh (TVM) surgeries from 2010 to 2012 were obtained from 135 medical centers belonging to the Japanese Society of Pelvic Organ Prolapse Surgery. The questionnaire addressed hospital volume, perioperative management, and SSI. Risk factors for SSI were investigated by comparing cases with and without SSI. RESULTS: The hospital volume among institutions varied from 0 to 248 per year (median 16.7). Preoperative hair removal, bowel preparation, and urine culture were routinely performed at 74 (55%), 66 (49%), and 24 (18%) hospitals, respectively. Prophylactic antimicrobials used were mostly first-generation (43%) or second-generation (42%) cephalosporin. SSI was reported in 86 of 9323 patients (0.92%). A multivariate analysis indicated lower hospital volume (odds ratio [OR], 0.995 [by 1-point increase]; P < 0.001), preoperative bowel preparation (OR, 2.08; P = 0.013), non-routine urine culture (OR, 3.00; P = 0.0006), and the use of antibiotics other than first-generation cephalosporin (OR, 5.29; P = 0.0011) as significant risk factors for SSI. In contrast, the cut-off points of hospital volume for preventing SSI was 116.7 cases (area under curve: 0.61). CONCLUSION: The prevalence of SSI in TVM surgeries was 0.92% in Japan. Lower hospital volume, bowel preparation, non-routine preoperative urine culture, and prophylactic antibiotics other than first-generation cephalosporin significantly elevated the incidence of SSI.

RESUMO

PURPOSE: To study the outcomes of mouse preimplantation embryos irradiated with low doses of X-rays (≤ 1 Gy) and investigate apoptosis and pluripotency of the irradiated embryos. METHODS: Mouse embryos at the 2-cell stage were collected for in vitro culture. After reaching the 8-cell stage, embryos were irradiated with various low doses of X-rays (0-1 Gy). Blastocysts with a normal appearance were transferred into a pseudopregnant uterus. The developmental rate to blastocysts and the survival rate following embryo transfer were examined. Expression levels of p21, Smad2, Foxo1, Cdx2, Oct4, and Nanog genes were measured by RT-PCR. Apoptotic cells in mouse blastocysts were examined immunofluorescently by staining for cleaved caspase-3. RESULTS: More than 90% of non-irradiated and low-dose X-ray-irradiated preimplantation embryos developed to morphologically normal blastocysts that could be implanted and survive in the uterus. However, embryos irradiated with X-rays had more apoptotic cells in a dose-dependent manner. Expression of p21, Smad2, and Foxo1 genes in X-ray-irradiated embryos was increased significantly, while expression of Cdx2, Oct4, and Nanog genes was maintained in comparison with non-irradiated embryos. CONCLUSIONS: Although irradiated embryos contained apoptotic cells, the low doses of irradiation did not disturb development of 8-cell stage embryos to blastocysts or their survival in utero. The underlying mechanisms might involve anti-apoptotic systems, including the Smad-p21 pathway, and preservation of pluripotency.

RESUMO

AIM: Apical prolapse includes descent of the uterus, vagina cuff, or rarely solely of the cervix. It is estimated that women have an 11-19% life-time risk of undergoing surgery for POP. This rate is projected to increase over the next 2-3 decades. In this FIGO working group report we address the conservative and surgical treatment options for apical prolapse. METHODS: The FIGO working group "Pelvic Floor Medicine and Reconstructive Surgery" describes the different treatments for apical prolapse based on the literature evidence, the cost-effectiveness, the degree of difficulty and summed them up with an experts recommendation. RESULTS: Among the conservative treatment options, pessaries are the most successful options since centuries with a low complication rate and low costs. Among the vaginal operative procedures the sacrospinous ligament fixation (SSLF) and the uterosacral ligament suspension (USLS) show comparable outcomes and efficacy with a different, however, rather low complication pattern and a favorable cost-benefit profile. Sacrocolpopexy, independent on the open abdominal, laparoscopic, or robotic-assisted laparoscopic technique has a good durability and quality of life performance. The minimal invasive techniques are as effective as the open abdominal techniques and there is no difference in mesh exposure. CONCLUSION: Vaginal procedures are well described procedures with favorable outcomes and cost-benefit profiles. Sacral colpopexy has a high-effectivity; data on the route of performance and long-term outcome are awaited. The cost with mesh implants are higher compared to the operations with autologous tissue or any conservative treatment and further studies are recommended to evaluate the cure rates in the span of decades and the possible long-term mesh complications.

RESUMO

OBJECTIVE: To investigate the differences in toll-like receptor (TLR)-mediated immune responses between human neonates and adults, focusing on the cytokine profiles of monocytes, dendritic cells (DCs), and monocyte-derived DCs (MoDCs) in cord and adult blood. STUDY DESIGN: Purified monocytes, DCs, and MoDCs were stimulated with the following TLR ligands: lipopolysaccharide (TLR4), Pam3CSK4 (TLR1/2), flagellin (TLR5), zymosan (TLR2), polyinosinic:polycytidylic acid (TLR3), imiquimod (TLR7), and CpG (TLR9). Interleukin (IL)-8, IL-6, tumor necrosis factor, IL-1ß, and IL-10 concentrations were analyzed in culture supernatants. RESULTS: Compared with the effects in adult blood, lipopolysaccharide-, Pam3CSK4-, flagellin-, and polyinosinic:polycytidylic acid-stimulated inflammatory cytokine production in cord blood was generally weak in monocytes, comparable in DCs, and elevated in MoDCs. CpG- and imiquimod-stimulated cytokine production in DCs was comparable in cord blood and adult blood, but cytokine production was almost absent in monocytes and MoDCs in both cord blood and adult blood. In contrast, zymosan stimulation produced comparable inflammatory cytokine profiles in the monocytes, DCs, and MoDCs of cord blood and adult blood. CONCLUSION: The immaturity of TLR-mediated innate immunity in neonates depends on monocytes rather than on DCs. Our results indicate that zymosan-mediated TLR2 signaling may be useful for developing a neonatal vaccine adjuvant.

RESUMO

OBJECTIVES: We aimed to construct reference ranges for time intervals of each component of cardiac flow velocity waveforms in normal fetuses, comparing those variables between right and left ventricles. METHODS: In 359 fetuses at the gestational age of 17-38 weeks, the durations of atrioventricular (AV) valve opening (AVVO), AV valve closure (AVVC), total E- (total-E) and A- (total-A) waves, total ejection time (total-ET), acceleration time (acc-E for E-wave, acc-A for A-wave, and acc-ET for ejection time), and deceleration time (dec-E for E-wave, dec-A for A-wave, and dec-ET for ejection time) were studied cross sectionally. RESULTS: Both right and left acc-E showed the strongest correlations with gestational age (r = 0.478 and r = 0.519, respectively). Left AVVO showed a stronger correlation (r = 0.474) than right AVVO (r = 0.282) and, conversely, right AVVC showed a stronger correlation (r = 0.399) than left AVVC (r = 0.195) with gestational age. Significant differences (all P values <0.001) were observed for all right and left parameters other than total-A and acc-E. CONCLUSIONS: Characteristic differences between right and left ventricles were found in the reference ranges, suggesting the developmental properties of the fetal heart. © 2014 John Wiley & Sons, Ltd.
