RESUMO

This article summarizes the recent activity of the International Stem Cell Banking Initiative (ISCBI) held at the California Institute for Regenerative Medicine (CIRM) in California (June 26, 2016) and the Korean National Institutes for Health in Korea (October 19-20, 2016). Through the workshops, ISCBI is endeavoring to support a new paradigm for human medicine using pluripotent stem cells (hPSC) for cell therapies. Priority considerations for ISCBI include ensuring the safety and efficacy of a final cell therapy product and quality assured source materials, such as stem cells and primary donor cells. To these ends, ISCBI aims to promote global harmonization on quality and safety control of stem cells for research and the development of starting materials for cell therapies, with regular workshops involving hPSC banking centers, biologists, and regulatory bodies. Here, we provide a brief overview of two such recent activities, with summaries of key issues raised. Stem Cells Translational Medicine 2017;6:1956-1962.

RESUMO

The aim of this study is to obtain a quantitative anatomical description of the hyoid bone and mandible using three-dimensional computed tomography. Hyoid bones were obtained from a total of 101 cadavers varying in age from 67 to 102 years. The percentage of symmetrical U-type and asymmetrical-type hyoid bones was low compared with symmetrical V type (14.9, 15.8, and 69.3 %, respectively), and no significant sex difference was observed. We found bilateral nonfusion in cadavers of advanced age at a rate of 22.7 % and bilateral complete fusion at a rate of 51.5 %. There were significant differences in metric variables (length and width) between males and females, but no significant differences in width among the different fusion types. There was no significant interaction effect of sex and degree of fusion. Strong significant associations were observed between size (length and width) of the hyoid bone and mandible in the nonfusion group, while the complete fusion group revealed a moderate correlation. We also investigated the hypothesis that the junction between the hyoid body and greater horn plays an important role in the movement of bones that have not yet ossified. However, no statistical difference was observed in the width between the two greater horns. The degree of fusion of the greater horn with the hyoid body may also affect relations of interdependencies between the hyoid bone and mandible, an important component to consider when assessing risk factors in the development of masticatory and swallowing function.

RESUMO

OBJECTIVE: To investigate clinical features of mirror syndrome. METHODS: We retrospectively reviewed 71 cases of fetal hydrops with or without mirror syndrome, and compared with respect to maternal age, the body mass index, the primipara rate, the gestational age at delivery, the timing of fetal hydrops onset, the severity of fetal edema, placental swelling, the laboratory data and the fetal mortality. The data are expressed as the medians. RESULTS: Mirror syndrome developed in 29% (10/35) of the cases with fetal hydrops. In mirror group, the onset time of fetal hydrops was significantly earlier (29 weeks versus 31 weeks, p = 0.011), and the severity of fetal hydrops (fetal edema/biparietal diameter) was significantly higher than non-mirror group (0.23 versus 0.16, p < 0.001). There was significantly higher serum human chorionic gonadotropin (hCG) (453,000 IU/L versus 80,000 IU/L, p < 0.001) and lower hemoglobin (8.9 g/dL versus 10.1 g/dL, p =0.002), hypoalbuminemia (2.3 mg/dL versus 2.7 mg/dL, p = 0.007), hyperuricemia (6.4 mg/dL versus 5.0 mg/dL, p = 0.043) in mirror group. CONCLUSION: Mirror syndrome is occurred frequently in early and severe fetal hydrops and cause hemodilution and elevation of serum hCG.

RESUMO

Maternal status epilepticus can cause fetal hypoxic ischemic encephalopathy that in turn results in acute polyhydramnios caused by fetal dysphagia; thus, acute polyhydramnios is a symptom that should lead to a suspicion of fetal dysphagia caused by hypoxic ischemic encephalopathy.

RESUMO

OBJECTIVE: To investigate the association between neurodevelopmental complications and biparietal diameter (BPD) growth rate. MATERIALS AND METHODS: The patients were pregnant women with severe fetal growth restriction (< 5(th) percentile) before 30 weeks who delivered after 24 gestational weeks. We defined poor BPD growth as being at least 50% below the mean growth rate for at least 1 week. We analyzed maternal characteristics, neonatal complication morbidities, perinatal mortality rate, and neurodevelopmental complications in the child at age 2 years (corrected). RESULTS: BPD growth was categorized as normal or poor. Out of 8254 infants, 26 met the above criteria. The poor BPD growth group included 17 infants and the normal BPD growth group included nine infants. The gestational age at delivery was 28.7 (24.7-31.7) weeks in the poor BPD growth group and 28.5 (26.1-32.4) weeks in the normal BPD growth group, showing no significant difference. However, death or neurodevelopmental complications occurred in eight of the 17 infants in the poor BPD growth group, whereas neither death nor neurodevelopmental complications were observed in the normal BPD growth group (p = 0.009). Moreover, in those with poor outcomes, BPD growth rates were consistently below 40% and birth weights were < 700 g. CONCLUSION: BPD growth was associated with neurodevelopmental outcomes, and growth delay as compared with the mean growth rate is a risk factor for poor neurodevelopment.

RESUMO

Introduction. To investigate the effect of complex umbilical cord entanglement primarily around the trunk on pregnancy outcomes. Methods. We studied 6307 pregnant women with singleton pregnancies who underwent vaginal delivery of an infant at ≥37 weeks of gestation. Cases were classified into no cord, nuchal cord, and body cord groups and defined as cases without umbilical cord entanglement, one or more loops of the umbilical cord around the neck only, and umbilical cord around the trunk only, respectively. Pregnancy outcomes were compared among these three groups. Results. The no cord, nuchal cord, and body cord group included 4733, 1451, and 123 pregnancies, respectively. Although delivery mode was not significantly different among the three groups, 1-minute Apgar scores <7 and umbilical artery (UA) pH <7.10 were significantly more common in the umbilical cord entanglement groups than in the no cord group. In particular, the frequency of 5-minute Apgar scores <7 was significantly higher (P = 0.004), whereas that of UA pH <7.10 tended to be higher (P = 0.057) in the body cord group than in the nuchal cord group. Conclusion. Compared to nuchal cord, umbilical cord entanglement around the trunk was associated with a higher risk of low Apgar scores and low UA pH.

RESUMO

OBJECTIVES: Systemic lupus erythematosus (SLE) flare and preeclampsia are difficult to differentiate from each other and occasionally coexist; This study aimed to analyze cases requiring termination of pregnancy due to SLE flare or preeclampsia and to elucidate the association between these two conditions; Methods. Out of 71 pregnancies in 60 women managed for SLE-complicated pregnancies who delivered at or after 22 weeks' gestation at a tertiary center, 7 pregnancies were terminated due to uncontrollable severe SLE flare or severe preeclampsia We retrospectively analyzed the clinical courses and laboratory findings of these 7 cases to determine whether their pathological conditions were attributable to SLE flare alone, preeclampsia alone, or the coexistence of these two conditions. RESULTS: One of the 7 cases had preeclampsia alone, two had SLE alone, and four had both conditions. The coexistence of preeclampsia and SLE was thus the most common condition. In cases with both conditions, SLE flare had preceded preeclampsia, thereby making treatment after delivery difficult. CONCLUSION: Severe SLE flare often preceded severe preeclampsia and worsened after delivery. When differentiating severe SLE flare from severe preeclampsia is difficult during pregnancy, women should be regarded as having SLE flare rather than preeclampsia and aggressively treated.

RESUMO

PURPOSE: Synovial plicae and their relation to pain and disability have been reported in the orthopedic literature in association with the knee and other extremity joints. However, the occurrence of synovial plicae in the temporomandibular joint (TMJ) have rarely been reported. This report describes the surgical appearance, distribution, and histologic findings of synovial plicae in patients with TMJ recurrent dislocation and internal derangement. MATERIALS AND METHODS: Twenty consecutive patients, 16 with recurrent dislocation and 4 with internal derangement, who underwent open TMJ surgery by the same surgeon from 2010 to 2013 were studied retrospectively. RESULTS: Synovial plicae were detected in 18 of 28 joints (64.3%). Synovial plicae were observed in 15 of 24 joints (62.5%) with recurrent dislocation and in 3 of 4 joints (75%) with internal derangement. Histologic findings of these plicae were consistent with dense fibrous or cartilaginous tissues, with some exhibiting a synovial lining. CONCLUSIONS: Although the role of synovial plicae in TMJ disorders is unknown and unstudied, consideration should be given to investigating the possible relation of these structures to the signs and symptoms of TMJ disorders.

RESUMO

AIM: To investigate the clinical features of gestational thrombocytopenia (GT) difficult to differentiate from immune thrombocytopenia (ITP) during pregnancy. METHODS: The January 2000-December 2012 hospital database was analyzed to identify women with ITP or GT (after excluding other possible causes of thrombocytopenia) among those first noted to have platelet counts of less than 100 000/µL during pregnancy. The maternal characteristics, platelet count fluctuations and pregnancy outcomes were compared between women with ITP and GT. RESULTS: There were 23 pregnancies (22 women) with thrombocytopenia (GT, 13; ITP, 10). The GT group included five twin pregnancies (38.5%), whereas all pregnancies of the ITP group were singleton pregnancies, with significantly more twin pregnancies in the GT group (P = 0.046). Thrombocytopenia in the first trimester occurred in 70% (7/10) of ITP cases and 23.1% (3/13) of even GT cases. The nadir platelet count was less than 70 000/µL in 100% (10/10) of ITP cases and 30.8% (4/13) of GT cases (P < 0.001). Maternal treatment was required in 80% (8/10) of ITP cases, but in none of the GT cases. The pregnancy outcomes were favorable in both groups, and no case required fetal treatment. CONCLUSION: Gestational thrombocytopenia with platelet counts of less than 10 0000/µL occurred more frequently in twin pregnancies. Although onset of thrombocytopenia in the first trimester and a platelet count of less than 70 000/µL is more common in ITP, these findings were not uncommon in GT. Differentiation between ITP and GT may be feasible only with post-partum changes in the platelet count.

RESUMO

AIM: The aim of this study was to elucidate the risk of poor pregnancy outcomes in women with adenomyosis by comparing their outcomes to those of women without uterine abnormalities. MATERIAL AND METHODS: The subjects were 36 women diagnosed with adenomyosis before pregnancy who were managed at a tertiary care center between January 2002 and December 2012. Our hospital database was retrospectively reviewed to identify pregnancy outcomes associated with adenomyosis. The control group consisted of 144 women without uterine abnormalities who gave birth during the same period and whose age at delivery was adjusted by applying propensity scores. Pregnancy outcomes were compared between the adenomyosis and control groups. The main outcomes were gestational age at delivery, preterm delivery, preterm premature rupture of membranes, fetal malpresentation, cesarean delivery, small-for-gestational age, 5-min Apgar score < 7, umbilical arterial pH < 7.1, and neonatal intensive care unit admission. The data are presented as medians (range) or frequencies (percentage). RESULTS: The adenomyosis group had significantly higher rates of preterm delivery (41.7% vs 12.5%), preterm premature rupture of membranes (19.4% vs 4.2%), small-for-gestational age (33.3% vs 10.4%), fetal malpresentation (27.8% vs 8.3%), and cesarean delivery (58.3% vs 24.3%), as compared with the control group. No significant differences were observed in 5-min Apgar score < 7 or umbilical arterial pH < 7.1 between the two groups. CONCLUSIONS: Pregnancies in women with adenomyosis were associated with a higher preterm delivery rate and more frequent occurrences of fetal growth restriction and fetal malpresentation, such that both pregnancy and delivery outcomes were poor.

RESUMO

AIMS: Placental abruption is an important cause of perinatal mortality and morbidity. Although there are many reports on the risk factors for placental abruption, there are few on its classification. Our aim is to evaluate the associations between primary symptoms and the outcomes of placental abruption. MATERIAL AND METHODS: We carried out a retrospective cohort study of 12,474 births at the Perinatal Center for Maternity and Neonates of the Yokohama City University Medical Center between January 2000 and December 2012. There were 151 women with placental abruption, 136 of whom were included in this study. The subjects were classified into two groups according to their primary symptoms: those with bleeding (external bleeding group) and those with abdominal pain (abdominal pain group). Maternal and neonatal outcomes were compared between the two groups. RESULTS: Both fetal and maternal outcomes were significantly poorer in the abdominal pain group than in the external bleeding group in terms of intrauterine fetal death (6.5% vs 33.3%, P < 0.001), perinatal mortality (8.1% vs 33.3%, P = 0.001), umbilical arterial pH < 7.1 (15.7% vs 57.1%, P < 0.001), bleeding volume, rate of blood transfusion, and disseminated intravascular coagulation incidence. CONCLUSIONS: This classification based on primary symptoms was found to be useful for predicting both maternal and neonatal outcomes of placental abruption.

RESUMO

Acute respiratory failure occurs in less than 0.1% of pregnancies. Thyroid storm should be included in the differential diagnosis of possible causes of acute respiratory failure occurring immediately after delivery, and delivery is a high risk factor for thyroid storm in pregnant women with thyrotoxicosis.

RESUMO

Aims. To analyze the pregnancy outcomes of circumvallate placenta retrospectively and to predict circumvallate placenta during pregnancy based on its clinical features. Methods. The pregnancy outcomes of 92 women with circumvallate placenta who delivered live singletons at a tertiary care center between January 2000 and September 2012 were compared with those of 9057 controls. Results. Women with circumvallate placenta were associated with higher incidences of preterm delivery (64.1%), placental abruption (10.9%), emergency cesarean section (45.6%), small-for-gestational age (36.9%), neonatal death (8.9%), neonatal intensive care unit admission (55.4%), and chronic lung disease (33.9%). When vaginal bleeding during the second trimester and premature chemical rupture of membranes (PCROM) were both used as predictive factors for circumvallate placenta, the sensitivity was 28.8% and specificity was 99.9%. Conclusion. With circumvallate placenta, pregnancy outcomes were poor and had characteristic clinical manifestations. In women with both vaginal bleeding and PCROM during pregnancy, circumvallate placenta should be strongly suspected.

RESUMO

We report our experience with a case of presumptive cesarean scar pregnancy, based on detection of a gestational sac (GS) in early pregnancy at the site of a previous cesarean scar. The GS grew into the uterine cavity as the pregnancy progressed, showing an ultrasound image similar to that of a normal pregnancy. Thus, the pregnancy continued, resulting in a viable birth at 28 weeks of gestation. Cesarean scar pregnancy is classified as myometrial implantation or implantation growth into the uterine cavity. In the latter type, the gestational sac moves upward with increasing gestational weeks and it shows the same ultrasound image as a normal pregnancy. Therefore, the diagnosis must be made in the early pregnancy.

RESUMO

In nuclear power plants, vibration stress of piping is frequently evaluated to prevent fatigue failure. A simple and fast measurement method is attractive to evaluate many piping systems efficiently. In this study, a method to measure the vibration stress using optical contactless displacement sensors was proposed, the prototype instrument was developed, and the instrument practicality for the method was verified. In the proposed method, light emitting diodes (LEDs) were used as measurement sensors and the vibration stress was estimated by measuring the deformation geometry of the piping caused by oscillation, which was measured as the piping curvature radius. The method provided fast and simple vibration estimates for small-bore piping. Its verification and practicality were confirmed by vibration tests using a test pipe and mock-up piping. The stress measured by both the proposed method and an accurate conventional method using strain gauges were in agreement, and it was concluded that the proposed method could be used for actual plant piping systems.

RESUMO

The 'Clinical Guidelines for Obstetrical Practice, 2011 edition' were revised and published as a 2014 edition (in Japanese) in April 2014 by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists. The aims of this publication include the determination of current standard care practices for pregnant women in Japan, the widespread use of standard care practices, the enhancement of safety in obstetrical practice, the reduction of burdens associated with medico-legal and medico-economical problems, and a better understanding between pregnant women and maternity-service providers. The number of Clinical Questions and Answers items increased from 87 in the 2011 edition to 104 in the 2014 edition. The Japanese 2014 version included a Discussion, a List of References, and some Tables and Figures following the Answers to the 104 Clinical Questions; these additional sections covered common problems and questions encountered in obstetrical practice, helping Japanese readers to achieve a comprehensive understanding. Each answer with a recommendation level of A, B or C was prepared based principally on 'evidence' or a consensus among Japanese obstetricians in situations where 'evidence' was weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 104 Clinical Questions and Answers items, with the omission of the Discussion, List of References, and Tables and Figures, are presented herein to promote a better understanding among English readers of the current standard care practices for pregnant women in Japan.

RESUMO

OBJECTIVE: To evaluate pregnancy outcomes in women with uterine anomalies by applying a method for diagnosing and classifying congenital uterine malformations. DESIGN: Retrospective study. SETTING: Tertiary care center. POPULATION: Ninety-four women with uterine anomalies who delivered after 22 gestational weeks. METHODS: Excluding the 14 women with a history of surgery and seven with one endometrial cavity, 73 women with two endometrial cavities were subdivided into those with two external uterine orifices (2-OS subgroup) and those with one external uterine orifice (1-OS subgroup). MAIN OUTCOME MEASURES: Pregnancy outcomes, such as preterm birth, abnormal fetal presentation, cesarean delivery and placental abruption. RESULTS: The 2-OS subgroup comprised women with a didelphic or complete septate uterus who had a significantly higher rate of cesarean delivery (91% vs. 18%, p < 0.001) than the control group (normal uterine morphology; n = 5763). The 1-OS subgroup comprised women with a bicornuate or incomplete septate uterus who had significantly higher rates of preterm birth (27% vs. 5%, p < 0.001) and placental abruption (14% vs. 0.7%, p < 0.001) than the control group. CONCLUSIONS: Classification of uterine anomalies by the number of uterine endometrial cavities and external uterine orifices is an easy and reliable means of predicting pregnancy outcomes.
