Introduction The study analyzes and interprets possible effects of the COVID-19 pandemic on the preterm birth rate. Research questions included: were there fewer preterm births in Berlin in 2020, the first year of the pandemic, compared to the three years before the pandemic? Were there differences in preterm birth rates grouped according to weeks of gestation? Method The perinatal data of all singleton pregnancies were evaluated with regard to birth rates in Berlin, and the numbers of preterm neonates born in the three pre-pandemic years from 2017 to 2019 were compared to the rate for 2020, t…

Evaluation of vaccine coverage for low birth weight infants during the first year of life in a large managed care population.

OBJECTIVE: There are few recent population-based assessments of vaccine coverage in premature infants available. This study assesses and compares age- and dose-specific immunization coverage in children of different birth weight categories during the first year of life. METHODS: We performed a retrospective cohort analysis of computerized vaccination data from a large managed care organization in southern California. The participants were children born between January 1, 1997, and December 31, 2002, and continuously enrolled from birth to at least 12 months of age in the Southern California K

Modifying the risk of recurrent preterm birth: influence of trimester-specific changes in smoking behaviors.

BACKGROUND: Women with at least 1 prior occurrence of premature birth often have demographic and medical risk factors that are not modifiabl … first or second trimester was not significantly associated with an increase in recurrent premature birth rates (first trimester, 29% adjusted odds ratio, 0.97 [95% confidence interval, 0.9-1.1], and second trimester, 31% adjusted odds ratio, 1.10 [95% confidence interval, 0.9-1.3], respectively). However, quitting late in pregnancy (third trimester) was ass …

Perinatal mortality in Jinnah Postgraduate Medical Centre, Karachi.

During the one year period from 1st January to 31st December, 1989, there were 6,826 deliveries and 695 perinatal deaths, of these 553 were still-born and 142 were neonatal deaths (died within 7 days of birth). The perinatal mortality rate was 101.8 per thousand total births. The still-birth rate was 81 per thousand total births. Of the perinatal deaths, 7.9% occurred in booked and 92.1% in non-booked cases. The commonest cause of death was antepartum haemorrhage (APH), 24.2% followed by mechanical which accounted for 23.6% deaths. Abruptio placentae was the leading cause among all still-birth…

An effective strategy for rare microdissection testicular sperm involves utilizing a micro-cryopreservation technique combined with laser-assisted selection of immotile sperm after thawing.

The challenge with spermatozoa retrieval in non-obstructive azoospermia (NOA) patients is that testicular spermatozoa are frequently immotil … pregnancy rate (38% vs 50%), implantation rate (29% vs 38%), miscarriage rate (14% vs 12%), or live birth rate (31% vs 38%) (P > 0.05 for all). Among patients who underwent a freeze-all embryos strategy, the first frozen-thawed embryo transfer cycle yielded comparable clinical pregnancy rates for the micro-TESE-ICSI and TESA-ICSI groups (70% vs 57%), with no …

Birth outcomes by type of attendance at antenatal education: An observational study.

BACKGROUND: Antenatal education aims to prepare expectant parents for pregnancy, birth, and parenthood. Studies have reported antenatal education teaching breathing and relaxation methods for pain relief, termed psychoprophylaxis, is associated with reduction in caesarean section rates compared with general birth and parenting classes. Given the rising rates of caesarean section, we aimed to determine whether there was a difference in mode of birth in women based on the type of antenatal education attended. MATERIALS AND METHODS: A cross-sectional antenatal survey of nulliparous women ≥28 wee

OBJECTIVE: To compare the influence of maternal hemoglobin phenotype as well as that of the infant on birth outcome and neonatal complications. RESEARCH DESIGN: Prospective, natural history study with retrospective chart review for neonatal complications. SETTING: Nineteen pediatric sickle cell centers across the United States. PATIENTS: Four hundred eighty infants with sickle cell disease (SCD) who were enrolled in the Cooperative Study of Sickle Cell Disease at less than 6 months of age, as well as a comparison cohort of 118 infants with sickle cell trait born to women with sickle cell an

[Congenital atrial flutter with hydrops fetalis caused by tocolytic therapy (author's transl)].

A 31-year-old healthy woman received Ritodrine (Pre-Par) from the 26th week of gestation because of twin pregnancy. Three weeks before birth continous intravenous medication with the same drug was commenced because of premature uterine contractions. Five days later a heart rate of over 200/minute was noted in one of the twins. This tachycardia persisted until birth while the heart rate of the other twin remained normal. At 33 weeks monozygotic female twins were delivered after artifical rupture of membranes. One twin was normal, birth weight 1.6 kg. The other baby showed persistent atrial flut

Prevalence rates of heathy stomach mucosa, chronic non-atrophic and atrophic gastritis in endoscopic biopsies in adults born in Finland in 1890-1977.

BACKGROUND: Helicobacter pylori infection, chronic gastritis (CG) and atrophic gastritis (AG) are a continuum of consecutive events in the stomach mucosa. We studied the birth cohort and age group-specific prevalence rates of 'Работает' (N) and 'diseased' stomachs with CG or AG in endoscopic biopsies in adult people born in Finland in 1890-1977. MATERIALS AND METHODS: Study series consisted of 690 and 1608 adults with a diagnostic gastroscopy in 1972-1997. All subjects were divided to 10-year age groups and birth cohorts. Based on biopsy histology, relative frequencies (prevalences) of N, CG a

Use of prenatal diagnosis among parents of infants with spina bifida in Atlanta, Georgia, 1976-1979.

A follow-up was made of the parents of a population-based cohort of 154 infants with spina bifida who were born in Atlanta during 1972-1979. We interviewed the parents of these infants and, for pregnancies after the spina bifida-affected birth, the ratio of use of prenatal diagnosis and the rate of recurrence of spina bifida were ascertained. Among 43 pregnancies which occurred in 1976 or later, and which occurred after a spina bifida-affected birth, prenatal diagnosis was used for 27 pregnancies (63%). For whites, among full siblings born after a spina bifida-affected birth, the recurrence ra

Trends in postpartum haemorrhage.

OBJECTIVE: To assess trends and outcomes of postpartum haemorrhage (PPH) in New South Wales (NSW). METHODS: A population-based descriptive study of all 52,151 women who had a PPH either during the hospital stay for the birth of their baby or requiring a re-admission to hospital between 1994 and 2002. Data were obtained from the de-identified computerised census of NSW hospital in-patients and analysed to examine trends over time. The outcome measures included maternal death, hysterectomy, admission to intensive care unit (ICU), transfusion and major maternal morbidity, including procedures to

Use of quantitative fibronectin alone resulted in a predicted risk of preterm birth within 7 days that ranged from 2% in the group with the lowest fibronectin level (<10 ng/mL) to 3 …

Planned home births: the need for additional contraindications.

BACKGROUND: Planned home births in the United States are associated with fewer interventions but with increased adverse neonatal outcomes such as perinatal and neonatal deaths, neonatal seizures or serious neurologic dysfunction, and low 5-minute Apgar scores. The American College of Obstetricians and Gynecologists' Committee on Obstetric Practice states that, to reduce perinatal death and to improve outcomes at planned home births, strict criteria are necessary to guide the selection of appropriate candidates for planned home birth. The committee lists 3 absolute contraindications for a plann

Safety evaluation of single-sperm cryopreservation technique applied in intracytoplasmic sperm injection.

Intracytoplasmic sperm injection (ICSI) is a technique that directly injects a single sperm into the cytoplasm of mature oocytes. Here, we explored the safety of single-sperm cryopreservation applied in ICSI. This retrospective study enrolled 186 couples undergoing ICSI-assisted pregnancy. Subjects were allocated to the fresh sperm (group A)/single-sperm cryopreservation (group B) groups based on sperm type, with their clinical baseline/pathological data documented. We used ICSI-compliant sperm for subsequent in vitro fertilization and followed up on all subjects. The recovery rate/cryosurviva

Between 1954 and 1973, 101 heroin-addicted mothers gave birth to 149 babies at Vancouver General Hospital. Thirty-seven percent of the infan … lent, including alcohol, barbiturates, and "soft drugs." Neonatal mortality rate of 6.7% and a stillbirth rate of 4% resulted in a perinatal mortality rate of 10.7%. Prematurity, respiratory distress syndrome, and other perinatal complications related to an unfavorable social background accounted for most neonatal deaths, but none was attributable directly t …

Rotational forceps versus manual rotation and direct forceps: A retrospective cohort study.

OBJECTIVE: Rotational forceps and manual rotation followed by direct forceps are techniques used in the management of malposition of the fetal head in the second stage of labor. However, there is widespread debate regarding their relative safety and utility. We aimed to compare the effectiveness and safety of rotational forceps with manual rotation followed by direct forceps, for management of fetal malposition at full dilation. STUDY DESIGN: A retrospective cohort study in a single tertiary obstetric unit with >6000 births per year. We recorded and analysed outcomes of 104 sequential rotatio

Survival predictors of preterm neonates: Hospital based study in Iran (2010-2011).

BACKGROUND: Preterm birth (PTB) is responsible for 70% of neonatal mortalities. Various factors influence the risk of neonatal mortality in different populations. OBJECTIVE: Our objective was to evaluate neonatal survival rate of preterm infants, and to define its predictors in Iranian population. MATERIALS AND METHODS: This retrospective cohort study included all preterm (26-37 weeks) infants (n=1612) born alive in Shahid Akbar-abadi university hospital, during one year period (April 2010-2011). These infants were evaluated for fetal-neonatal, maternal, and pregnancy data. Survival analysis

Preterm birth or small for gestational age in a singleton pregnancy and risk of recurrence in a subsequent twin pregnancy.

OBJECTIVE: To evaluate whether a history of preterm birth or small for gestational age (SGA) in a singleton pregnancy is associated with an increased risk of recurrence of the same condition in a subsequent twin pregnancy. METHODS: Retrospective cohort study of twin pregnancies delivered in one maternal-fetal medicine practice from 2005 to 2014. Patients with a history of singleton preterm birth at less than 37 weeks of gestation were compared with patients with a history of singleton term birth and nulliparous patients. A similar analysis was performed for a history of SGA (birth weight less
