[Demographic and sociological setup of premature deliveries for live births in GDR 1973 (author's transl)].

A record was taken 1973 of 22,466 single and 3,287 multiple live births, with premature deliveries being subdivided by age, birth order, coverture, and vocational backgrounds of the mothers concerned. The distributions thus established have produced evidence to the effect that all the above factors may have an impact upon premature delivery. Yet, multiple births were found to distort the distributions of all parameters used. --- Reference is made to possible interpretations of such studies in terms of large-scale trends, resources, risk hypotheses, and clusters, with examples being proposed for the latter.

A time series approach to forecasting Australian total live-births.

The relationship between classical demographic deterministic forecasting models, stochastic structural econometric models and time series models is discussed. Final equation autoregressive moving average (ARMA) models for Australian total live-births are constructed. Particular attention is given to the problem of transforming the time series to stationarity (and Gaussianity) and the properties of the forecasts are analyzed. Final form transfer function models linking births to females in the reproductive age groups are also constructed and a comparison of actual forecast performance using the various models is made. Long-run future forecasts are generated and compared with available projections based on the deterministic cohort model after which some policy implications of the analysis are considered.

A healthy live birth after mosaic blastocyst transfer in preimplantation genetic testing for GATA1-related cytopenia combined with HLA matching.

BACKGROUND: GATA1-related cytopenia (GRC) is characterized by thrombocytopaenia and/or anaemia ranging from mild to severe. Haematopoietic stem cell transplantation (HSCT) is a healing therapeutic choice for GRC patients. We identified a novel pathogenic variant (GATA1: c.1019delG) in a boy with GATA1-related cytopenia. Then we performed preimplantation genetic testing (PGT) in this GRC family. After a mosaic embryo transfered, a healthy and HLA-compatible with the proband baby was delivered. CASE PRESENTATION: The proband is a 6-year-old boy who was diagnosed to have transfusion-dependent anaemia since 3 year old. Whole-exome sequencing (WES) showed that the proband has a hemizygous variant c.1019delG in GATA1, which is inherited from his mother. His parents decided to undergo PGT to have a health and HLA-compatible offspring. After whole genome amplification (WGA) of biopsied trophectoderm (TE) cells, next generation sequencing (NGS)-based PGT was preformed to analyse embryos on chromosomal aneuploidy, target mutation and HLA typing. There were 3 embryos HLA-matched to the proband. The genotypes of the 3 embryos were heterozygous variant, hemizygous variant, normal respectively. After a heterozygous, mosaic partial trisomy (chr)16, and HLA-matched embryo transfer, a healthy baby was delivered and whose HSCT is compatible with the proband. CONCLUSIONS: NGS-based PGT-HLA is a valuable procedure for the treatment of GATA1-related cytopenia caused by GATA1 variants, or other haematological disorders, oncological and immunological diseases. Furthermore, our study reconfirms that mosaic embryos transfer would bring healthy offspring.

Successful Live Birth Following Treatment of Persistent Endometrial Dysbiosis and Recurrent Chronic Endometritis: A Case Report.

CASE: To study the cause of recurrent endometritis, which recurred after standard antibiotic therapy, we report the case of a 40-year-old woman with a history of recurrent pregnancy, preterm birth, and CE. The endometritis recurred following a standard antibiotic regimen. OUTCOME: Microbiome analysis via 16S rRNA gene sequencing revealed persistent dysbiosis in both vaginal and endometrial samples despite antibiotic regimens. Whole-exome sequencing (WES) identified rare variants in TRPV3 and CD36, potentially associated with epithelial barrier dysfunction. Following an extended course of antibiotic therapy, the woman gave birth to a healthy baby at GA 32 weeks. CONCLUSIONS: This case highlights the possibility that barrier gene variants may be associated with persistent endometrial dysbiosis and recurrence of CE. An intensive antibiotic regimen may help achieve a viable pregnancy in patients with recurrent CE following standard antibiotic therapy.

Is the aeration of the lungs a reliable sign of live birth?

One of the most important medico-legal questions is whether an infant was born alive or not. The aerated lungs do not mean in every case that the newborn had taken a breath. Under various conditions the aerated lungs may turn into unaerated ones and, on the other hand, a stillborn's lungs may seem aerated. The critical evaluation of the histological and macroscopical examinations may aid in solving the question.

[Weight distribution of live births in the GDR (German Democratic Republic) in 1973].

Birth-weight-distributiones of life-borns in the GDR in 1973 show differences in all parameters as in sex of children as in professional qualification of women at the time of confinement. The results indicate the necessity to take norms of birth-weight as changeable in time and locality. It is necessary to actualize these norms continuously.

Causal association of menstrual reproductive factors on the risk of osteoarthritis: A univariate and multivariate Mendelian randomization study.

OBJECTIVE: Several observational studies have revealed a potential relationship between menstrual reproductive factors (MRF) and osteoarthritis (OA). However, the precise causal relationship remains elusive. This study performed Mendelian randomization (MR) to provide deeper insights into this relationship. METHODS: Utilizing summary statistics of genome-wide association studies (GWAS), we conducted univariate MR to estimate 2 menstrual factors (Age at menarche, AAM; Age at menopause, AMP) and 5 reproductive factors (Age at first live birth, AFB; Age at last live birth, ALB; Number of live births, NLB; Age first had sexual intercourse, AFSI; Age started oral contraceptive pill, ASOC) on OA (overall OA, OOA; knee OA, KOA and hip OA, HOA). The sample size of MRF ranged from 123846 to 406457, and the OA sample size range from 393873 to 484598. Inverse variance weighted (IVW) method was used as the primary MR analysis methods, and MR Egger, weighted median was performed as supplements. Sensitivity analysis was employed to test for heterogeneity and horizontal pleiotropy. Finally, multivariable MR was utilized to adjust for the influence of BMI on OA. RESULTS: After conducting multiple tests (P<0.0023) and adjusting for BMI, MR analysis indicated that a lower AFB will increase the risk of OOA (odds ratio [OR] = 0.97, 95% confidence interval [CI]: 0.95-0.99, P = 3.39&#xd7;10-4) and KOA (OR = 0.60, 95% CI: 0.47-0.78, P = 1.07&#xd7;10-4). ALB (OR = 0.61, 95% CI: 0.45-0.84, P = 2.06&#xd7;10-3) and Age AFSI (OR = 0.66, 95% CI: 0.53-0.82, P = 2.42&#xd7;10-4) were negatively associated with KOA. In addition, our results showed that earlier AMP adversely affected HOA (OR = 1.12, 95% CI: 1.01-1.23, P = 0.033), and earlier ASOC promote the development of OOA (OR = 0.97, 95% CI: 0.95-1.00, P = 0.032) and KOA (OR = 0.58, 95% CI: 0.40-0.84, P = 4.49&#xd7;10-3). ALB (OR = 0.98, 95% CI: 0.96-1.00, P = 0.030) and AFSI (OR = 0.98, 95% CI: 0.97-0.99, P = 2.66&#xd7;10-3) also showed a negative association with OOA but they all did not pass multiple tests. The effects of AAM and NLB on OA were insignificant after BMI correction. CONCLUSION: This research Certificates that Early AFB promotes the development of OOA, meanwhile early AFB, ALB, and AFSI are also risk factors of KOA. Reproductive factors, especially those related to birth, may have the greatest impact on KOA. It provides guidance for promoting women's appropriate age fertility and strengthening perinatal care.

[Infant mortality in cuba; analysis of a program for its reduction (1970-1976)].

Analysis is made of the results of the reduction program of infantile mortality which began in 1970. Said reduction dropped from 38.7 in 1970 to 22.8 per thousand live births in 1976, for a diminution of 41.5%. The early neonatal decreased from 18.2 to 12.3 per thousand live births for a drop of 32.7%. The late noenatal decreased from 5.3 to 2.30/100 live births with 57.2% reduction and the postneonatal dropped from 15.2 to 8.2 per thousand live births for a diminution of 46.5%. Infantile mortality is reported for the different departments and the order in which the main causes of death are grouped is stressed as follows; 1st, perinatal affections (B43-B44); 2nd, congenital anomalies (B42); 3rd, influenza and pneumonia (B31-B32); 4th, enteritis and other acute diarrheal diseases (B4) AND 5th, sepsis (A21). The average number of puericulture office visits per infant under 1 year of age increased from 2.7 to 6.7. Institutional births increased from 93.3 to 97.8%. The steps taken to achieve these results are described.

Incidence rates for cleft lip and palate in British Columbia 1952-71 for North American Indian, Japanese, Chinese and total populations: secular trends over twenty years.

The incidence of cleft lip and/or cleft palate was examined for the 1952-71 period for the Province of British Columbia. Although there were some fluctuations, some of which were significant, there was no general trend which indicated that the rates were either increasing or decreasing. These rates are important for a background calculation when investigating new invironment teratogens. The total rate of 1.97 per 1,000 live birth is comparable with other Caucasian populations where there is good ascertainment and adequate follow-up period. This study also confirmed the previously reported high rate for North American Indians in British Columbia (3.74 per 1,000 live births) and established rates for the Japanese (3.36 per 1,000 live births) and Chinese (1.76 per 1,000 live births) of British Columbia. Since these three sub-populations are relatively small in relation to the total population, they do not influence the overall total rate to any great extent.
