Pregnancy and Postpartum Trends in Self-Measured Blood Pressure and Derived Indices: The BOSHI Study.

In this study, we aimed to reveal the trends of self-measured blood pressure (SMBP) and SMBP-derived indices during pregnancy and the postpartum period. The Babies and Their Parents Longitudinal Observation in Suzuki Memorial Hospital in the Intrauterine Period (BOSHI) Study is a prospective cohort study in Japan. Participants were instructed to measure SMBP daily during pregnancy and for 1 month after delivery.

Associations of fasting plasma glucose and glycosylated hemoglobin levels at less than 24 weeks of gestation with hypertensive disorders of pregnancy: the BOSHI study.

This study aimed to evaluate the associations of fasting plasma glucose (FPG) and glycosylated hemoglobin (HbA1c) levels at <24 weeks of gestation with hypertensive disorders of pregnancy (HDP) and compare the strengths of the associations of HDP with FPG and HbA1c levels. Totally, 1,178 participants were included in this prospective cohort study. HDP, FPG, HbA1c, and potential confounding factors were included in multiple logistic regression models.

Laparoscopy-assisted vasovasostomy for post-herniorrhaphy vas deferens obstruction.

Introduction: Repair of obstructive azoospermia caused by childhood herniorrhaphy may be difficult. Therefore, intracytoplasmic sperm injection using testicular sperm is performed. However, vasovasostomy combined with laparoscopic surgery is challenging.

Examining the trimester-specific effects of low gestational weight gain on birthweight: the BOSHI study.

Low gestational weight gain (GWG) is a known risk factor of low birthweight. Although studies have previously examined the associations between GWG and birthweight, the period-specific effects of low GWG in each trimester remain unclear. This study aimed to quantify the trimester-specific direct effects of low GWG in Japanese women on birthweight.

Association of maternal home blood pressure trajectory during pregnancy with infant birth weight: the BOSHI study.

This study investigated the association between maternal home blood pressure (HBP) trajectory during pregnancy and infant birth weight. A total of 755 pregnant women were included in this prospective cohort study. A group-based trajectory model identified six trajectory groups for home systolic blood pressure (SBP), diastolic BP (DBP), and mean arterial pressure (MAP).

Utility of Laparoscopic Uterine Myomectomy as a Treatment for Infertility with No Obvious Cause Except for Uterine Fibroids.

Objectives: Uterine fibroids are capable of causing infertility, but there are no definite criteria for which laparoscopic uterine myomectomy (LM) is known to be beneficial. To investigate the usefulness of LM, we examined pregnancy rates in patients with infertility with no obvious cause except for the presence of uterine fibroids.

Materials And Methods: We retrospectively reviewed the clinical records at Suzuki Memorial Hospital between June 2010 and August 2014.

Reference values and associated factors for Japanese newborns' blood pressure and pulse rate: the babies' and their parents' longitudinal observation in Suzuki Memorial Hospital on intrauterine period (BOSHI) study.

Objective: Currently, normative means and ranges of blood pressure (BP) and pulse rates in Japanese newborns are not available. The objective of the present study was to estimate BP, pulse rate, and their distribution among Japanese newborns.

Methods: Using oscillometric devices, arm or calf BP and pulse rate levels were obtained from 3148 infants born between 2007 and 2014, consecutively at Suzuki Memorial Hospital, Iwanuma, Japan.

Maternal clinic and home blood pressure measurements during pregnancy and infant birth weight: the BOSHI study.

This prospective cohort study compared measurements of maternal home blood pressure (HBP) with clinic blood pressure (CBP) before 20 weeks' gestation to determine associations with the risk of delivering a lower birth weight infant. A total of 605 Japanese women were included. Exposures were initial CBP, made between 10 weeks 0 days and 19 weeks 0 days, and HBP for comparison made within 1 week of CBP.

Salt intake and the validity of a salt intake assessment system based on a 24-h dietary recall method in pregnant Japanese women.

Background: Information regarding salt intake in pregnant women in Japan is limited. An electronic system for the assessment of salt intake using a 24-h dietary recall method has been developed in Japan. The objectives of the present study were to investigate salt intake in pregnant women and to compare the salt intake estimated by the electronic salt intake assessment system with that measured by 24-h urinary salt excretion (24-hUNaCl).

Parity as a factor affecting the white-coat effect in pregnant women: the BOSHI study.

Parity has previously been reported to affect the difference in blood pressure (BP) measured in the office and at home, also known as the white-coat effect, during pregnancy. The objective of this study was to identify possible factors that cause the white-coat effect during pregnancy, focusing on parity. In total, 530 pregnant women (31.

Association of achondroplasia with Down syndrome: difficulty in prenatal diagnosis by sonographic and 3-D helical computed tomographic analyses.

Achondroplasia and Down syndrome are relatively common conditions individually. But co-occurrence of both conditions in the same patient is rare and there have been no reports of fetal analysis of this condition by prenatal sonographic and three-dimensional (3-D) helical computed tomography (CT). Prenatal sonographic findings seen in persons with Down syndrome, such as a thickened nuchal fold, cardiac defects, and echogenic bowel were not found in the patient.

Generation of healthy cloned mice using enucleated cryopreserved oocytes.

The successful generation of cloned animals and the establishment of embryonic stem (ES) cell lines from somatic cells suggest that these techniques may be used in human regenerative medicine. However, the fact that oocytes must be donated by women undergoing infertility treatment remains a fundamental ethical objection, as they might be concerned about the potential exploitation of their genome. Here, we investigated the reprogramming potential of enucleated and cryopreserved oocytes for the development of full-term cloned mice.

Fetal cell microchimerism develops through the migration of fetus-derived cells to the maternal organs early after implantation.

Fetus-derived cells are present in the blood and tissues of the maternal body over a long period of time, even after delivery, resulting in fetal cell microchimerism. The exact process by which fetal cells cross the placental barrier to enter the maternal circulation is unclear. The objective of this paper was to determine the time during pregnancy that fetal cells with multilineage potential migrate to the maternal organs.

Novel alpha-fetoprotein-V messenger RNA isoforms in humans.

It has been demonstrated that several messenger RNA (mRNA) isoforms have been transcribed from the alpha-fetoprotein (AFP) gene. In rats, it was reported that the novel exon, termed the exon V, exists between the exons 7 and 8, and the novel mRNA isoform (termed AFP-V mRNA) is synthesized using the exon V. In this study, a reverse transcription-polymerase chain reaction was performed and quantitative analysis was done on the AFP mRNA to identify the exon V and the AFP-V mRNA in humans.

Clinical impact of preoperative screening for gastric mucin secretion in cervical discharge by HIK1083-labeled latex agglutination test.

The present study evaluated the clinical impact of preoperative screening for gastric mucin in cervical discharge, using a latex agglutination test with HIK1083, a monoclonal antibody against gastric mucin. HIK1083-labeled latex agglutination tests were performed preoperatively using cervical secretions from 44 patients (group 1) with profuse watery vaginal discharge, multiple cervical cysts on vaginal ultrasonography, or yellowish mucin on a Papanicolaou smear and from 31 patients (group 2) with none of these clinical signs. The results were positive in 26 patients in group 1 and in no patients in group 2.

Intranuclear cytoplasmic inclusion is a significant diagnostic feature for the differentiation of lobular endocervical glandular hyperplasia from minimal deviation adenocarcinoma of the cervix.

Lobular endocervical glandular hyperplasia (LEGH) is a cervical lesion with pyloric gland metaplasia. Minimal deviation adenocarcinoma (MDA) is an extremely well differentiated form of endocervical adenocarcinoma (AC). To date, it is difficult to differentiate LEGH from MDA because they share similar clinical, radiological, and immunohistochemical features.

Milk inhibits the regression of 7,12-dimethylbenz(a)anthracene-induced mammary tumors in ovariectomized rats.

Epidemiological studies have yielded inconsistent results regarding the relation between the milk consumption and breast cancer risk. In this study, rats were induced mammary tumors by 7,12-dimethylbenz(a)anthracene. When tumors developed to acceptable levels, rats were placed into 1 of 3 treatment groups.

Consumption of commercial whole and non-fat milk increases the incidence of 7,12-dimethylbenz(a)anthracene-induced mammary tumors in rats.

Background: Breast cancer has become the most common cancer among women worldwide. Although the consumptions of milk and dairy products were considered to be a risk factor for breast cancer in some epidemiological studies, the results were inconsistent.

Methods: In the present study, female Sprague-Dawley rats received a single oral dose of 5mg 7,12-dimethylbenz(a)anthracene (DMBA).

Commercial soy milk enhances the development of 7,12-dimethylbenz(a)anthracene-induced mammary tumors in rats.

Background: Soy milk is a major soy food in China and Japan. Isoflavones in soy food are considered to protect women again breast cancer.

Materials And Methods: The effects of soy milk consumption on 7,12-dimethylbenz(a) anthracene (DMBA)-induced mammary tumors in adult female rats was investigated.

Milk consumption is a risk factor for prostate cancer in Western countries: evidence from cohort studies.

We have previously found a positive association between milk consumption and prostate cancer risk using meta-analysis to analyze published case-control studies. In the present study, further meta-analysis was conducted to estimate the summary relative risk (RR) between the consumption of milk and dairy products and prostate cancer from cohort studies published between 1966- 2006. We found 18 relevant articles and 13 independent studies were available for our analysis.

Estimation of prognoses for cervical intraepithelial neoplasia 2 by p16INK4a immunoexpression and high-risk HPV in situ hybridization signal types.

The present study used immunohistochemical staining and in situ hybridization (ISH) to examine whether progression of cervical intraepithelial neoplasia, grade 2 (CIN 2) can be predicted by p16INK4a immunoexpression and high-risk human papilloma virus (HPV) ISH signal types. We studied 52 cases histologically diagnosed with CIN 2: dysplasia regressed in 28 cases; 13 cases progressed to CIN 3; and CIN 2 persisted in 11 cases. Expression of p16INK4a and high-risk HPV signal both related to grade of CIN.

Lobular endocervical glandular hyperplasia as a presumed precursor of cervical adenocarcinoma independent of human papillomavirus infection.

Objectives: The aim of this study was to investigate differences in the process of carcinogenesis between adenocarcinoma coexistent with LEGH and conventional adenocarcinoma. And we intend to describe appropriate treatment plans for LEGH in this study.

Methods: Using the surgical pathology files of patients who visited the University of Yamanashi Hospital, Yamanashi Central Hospital and Kofu Municipal Hospital between 1996 and 2005, pathological diagnoses were reevaluated based on criteria for the diagnosis of LEGH by Nucci et al.

Soyfood intake in the prevention of breast cancer risk in women: a meta-analysis of observational epidemiological studies.

Many studies have suggested that the intake of soy products may protect against the occurrence of breast cancer because of the considerable amount of isoflavones they contain. To review the results of the observational studies, we performed this meta-analysis of the relevant literature. We searched Medline for reports that examined the association between soyfood consumption (or isoflavone intake) and breast cancer risk from January 1966 to April 2006.

Possible function of caudal nuclear pocket: degradation of nucleoproteins by ubiquitin-proteasome system in rat spermatids and human sperm.

Many temporarily functioning proteins are generated during the replacement of nucleoproteins in the nuclei of late spermatids and seem to be degraded in the nucleus. This study was designed to clarify the involvement of the ubiquitin-proteasome degradation system in the nucleus of rat developing spermatids. Thus, we studied the nuclear distribution of polyubiquitinated proteins (pUP) and proteasome in spermiogenic cells and sperm using postembedding immunoelectron microscopy.

There are gender differences in attitudes toward surrogacy when information on this technique is provided.

Objective: We analyzed the data of a nationwide opinion survey reported in a previous study and clarified the importance of socioeconomic status and individual belief on people's opinion regarding the pros and cons of gestational surrogacy. In this study, we analyzed the data of this nationwide opinion survey to identify the effect of providing information about assisted reproductive technology (ART) on the people's attitude towards not only gestational surrogacy but also other ART procedures.

Study Design: This was a cross-sectional study.
