Abstract

Purpose: Although the validity of self-reported osteoporosis is often questioned, validation studies are lacking. This study was performed to investigate how well self-reported diagnoses of osteoporosis agreed with validated clinical information in young and middle-aged women in the Japan Nurses’ Health Study (JNHS), a nationwide prospective cohort study of nursing professionals. Patients and Methods: Data were reviewed for 15,717 subjects from the combined cohorts of the JNHS and a preceding pilot study (Gunma Nurses’ Health Study). The subjects’ mean age at the baseline (BL) survey was 41.6 ± 8.3 years, and the mean follow-up period was 11.5 ± 4.4 years. Participating nurses were mailed a follow-up questionnaire every 2 years. Respondents who self-reported a positive osteoporosis diagnosis during the study period were sent an additional confirmation questionnaire to corroborate the details. Results: The number (proportion) of women with osteoporosis was 884 (5.6%) [primary osteoporosis, 812 (5.2%); secondary osteoporosis, 72 (0.5%)]. The cumulative incidence of osteoporosis at the age of 40, 50, 60, 70, and 80 years was estimated to be 0.1% (95% confidence interval, 0.1– 0.2), 1.1% (0.9– 1.3), 7.7% (7.0– 8.4), 23.6% (21.6– 25.7), and 54.2% (40.2– 68.1), respectively. For BL and regular follow-up + expert review versus BL and regular follow-up + confirmation questionnaire + expert review, the positive predictive value (PPV) was 61.3% versus 85.6% and the negative predictive value (NPV) was 98.9% versus 98.2%, respectively. Conclusion: Self-reporting was associated with a high NPV for the incidence of osteoporosis. Although the PPV was slightly lower, additional corroborations by confirmation questionnaire might improve the PPV.

35. Low Birth Weight and Prematurity Are Associated with Hypertensive Disorder of Pregnancy in Later Life: A Cross-Sectional Study in Japan.

Subjects
*HYPERTENSION in pregnancy, *NURSES' attitudes, *CONFIDENCE intervals, *CROSS-sectional method, *SELF-evaluation, *AGE distribution, *GESTATIONAL age, *RETROSPECTIVE studies, *LOW birth weight, *SURVEYS, *COMPARATIVE studies, *BIRTH weight, *QUALITY of life, *PARITY (Obstetrics), *DESCRIPTIVE statistics, *ODDS ratio, *WOMEN'S health, *DISEASE risk factors
Abstract

Objective  We previously reported that hypertensive disorder of pregnancy (HDP) was a risk factor for hypertension and hypercholesterolemia in later life. Additionally, the age-adjusted odds ratio (OR) of HDP was 2.72 for Japanese women whose mothers had a history of HDP versus those whose mothers did not. This study aimed to clarify the association of HDP with birth weight and gestational age. Study Design  A self-administered baseline survey of the Japanese Nurses' Health Study (JNHS) cohort was conducted from 2001 to 2007. Data on 17,278 parous female nurses who knew their own birth weights were extracted from the JNHS baseline survey (n  = 49,927) and subjected to cross-sectional, retrospective analysis. Data on weeks of gestation, birth weight, and history of HDP were collected. Results  The age-adjusted ORs for HDP were 1.62 (95% confidence interval [CI]: 1.20–2.19) for birth weight <2,000 g, 1.24 (CI: 1.04–1.48) for 2,000 to 2,499 g, 1.11 (CI: 1.00–1.23) for 2,500 to 2,999 g, and 1.08 (CI: 0.94–1.24) for ≥3,500 g compared with 3,000 to 3,499 g. The age-adjusted ORs for HDP were 1.27 (95% CI: 1.04–1.54) for a gestational age < 37 weeks and 0.93 (0.70–1.23) for ≥42 weeks compared with 37–41 weeks. The age-adjusted OR of the birth weight score for HDP in later life was 0.98 (CI: 0.94–1.03; Cochran–Armitage trend test: z  = 0.401, p  = 0.688). Conclusion  Among women in Japan, a history of low birth weight and prematurity are risk factors for HDP in later life. The risk of HDP among women born with low birth weight and/or premature deserves attention. [ABSTRACT FROM AUTHOR]

42. Molecular DNA Analysis of Methicillin-resistant Staphylococcus aureus (MRSA) Infection in a Neonatal Intensive Care Unit

Author

Subjects
neonatal intensive care unit (NICU), methicillin-resistant Staphylococcus aureus (MRSA), nosocomial transmission, bacterial infections and mycoses, neonatal toxic shock syndrome-like exanthematous disease (NTED), staphylococcal scalded skin syndrome (SSSS)
Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) infection in neonatal intensive care units (NICUs) has become a serious problem in Japan. MRSA nosocomial transmissions occurring in an NICU during 2001 and 2002 were investigated by pulsed-field gel electrophoresis and PCR. MRSA from a nosocomial transmission with incidences of neonatal toxic shock syndrome-like exanthematous disease (NTED) produced type II coagulase and possessed multiple superantigenic toxin genes for toxic shock syndrome toxin (TSST)-1, staphylococcal enterotoxin (SE) C, SEG, and SEI. MRSA from a nosocomial transmission with incidences of staphylococcal scalded skin syndrome (SSSS) was clonally distinct from the NTED-associated MRSA, produced type I coagulase, and possessed only the exfoliative toxin B gene (no previous superantigenic toxin genes were detected).

Abstract

Abstract: Hormone replacement therapy (HRT) plays a large part in maintaining and improving the quality of life (QOL) of postmenopausal women. Despite this obvious role, the use of HRT has stagnated in Japan as well as the United States, since the interim report of the HRT trial of Women's Health Initiative study was published in 2002. The Japan Society of Obstetrics and Gynecology and Japan Society for Menopause and Women's Health formulated the Guidelines for Hormone Replacement Therapy in 2009, which was subsequently revised in 2012, with the aim of organizing perceptions about HRT and allowing people to provide or receive HRT with a sense of security. Later on, in light of changes in indications for HRT and attitudes toward its impact on cancer risks, amendments were made again in 2017. With the establishment of the 2017 guidelines, practitioners in Japan are able to address various issues related to HRT with more appropriate judgment. Moreover, the practice of reliable, safe and effective HRT is expected to promote further efforts toward improvement or maintenance of QOL in patients. [ABSTRACT FROM AUTHOR]
