Environmental enrichment prevents pup mortality in laboratory mice.
2018
Early death of mouse pups is a commonly known problem in breeding mice colonies, which is still often regarded as ‘normal’ or is even overlooked due to the counting procedures applied. As reduced breeding performance probably indicates reduced well-being, this seems to be an underestimated welfare issue in laboratory mouse breeding. The present study compares the influence of three different forms of enrichment in breeding cages on infant survival rate and development of C57BL/6J mice. Our data reveal that lack of enrichment results in greater preweaning pup mortality, reduced weight and delayed development. Changing the environmental conditions after birth cannot prevent litter loss but i…
Exploring prenatal and neonatal life history through dental histology in infants from the Phoenician necropolis of Motya (7th–6th century BCE)
2023
The biological life history of infants from archaeological contexts can provide a unique insight into past human populations. Dental mineralized tissues contain a permanent record of their growth that can provide access to the prenatal and early infant life, and mortality, of human skeletons. This study focuses on the histomorphometric analysis of deciduous teeth from the ‘Archaic Necropolis’ of Motya (7th–6th century BCE, Sicily–Italy). The histomorphometric analysis is conducted on prenatal and postnatal enamel of eight anterior deciduous teeth from seven individuals from this Phoenician population to estimate their chronological age-at-death, health, and enamel growth parameters. Proteom…
Ramadan exposure and birth outcomes: a population-based study from the Netherlands.
2020
AbstractBackground:Ramadan, the Islamic month of daytime fasting, is observed by many pregnant Muslims. Although pregnant women are exempt, many prefer to fast. Previous research has shown long-term adverse effects on various health outcomes among the offspring, but evidence on effects on perinatal outcomes is mixed. This study investigates effects of Ramadan during pregnancy among Muslims in the Netherlands.Methods:Data from the Perinatal Registry of the Netherlands (Perined) on all births between 2000 and 2010 to mothers recorded as Mediterranean (i.e. of Turkish/Moroccan descent, a proxy for Muslim) (n = 139,322) or as ethnically Dutch (n = 1,481,435) were used. Ramadan exposure was defi…
Perinatal Database in Germany
1995
By collecting standardized data from up to 600,000 deliveries per year in Germany a nation-wide database has been established in recent years enabling not only regional and overregional quality control, but also the scientific analysis of rare maternal and fetal complication. During the observation period of 10 years the understanding of perinatal risk factors has considerably improved and the perinatal mortality has declined from 9.4 to 6.4 (per 1,000 deliveries). From the huge amount of calculations typical results are presented.
Risk Weighing in Twin Pregnancy
2010
Multiple pregnancies are more often associated with complications than singleton pregnancies. In our retrospective study of 613 twin pregnancies the most important risk factors in twin pregnancies were premature labour before the 37th week of gestation and the premature rupture of the membrane. The increase of perinatal mortality and morbidity for twins might be primary the result of premature delivery.
Congenital Pediatric Diseases
2008
Major congenital malformations are diagnosed in 4%–6% of all infants and fetuses (Lynberg and Edmonds 1992). About one third of them are the leading cause for infant mortality or morbidity (Grandjean et al. 1999). Malformations of the internal urogenital system are diagnosed in about 1% of all infants and account for approximately 20% of all congenital malformations, thus being one of the three most frequent birth defects (Table 11.1.1). Therefore a pre- and/or postnatally performed ultrasound screening for malformations of the internal urogenital system should be part of the routine to reduce perinatal mortality and morbidity. The reliability and value of ultrasonographic screening for con…
Prediction Models for Age-at-Death Estimates for Calves, Using Unfused Epiphyses and Diaphyses
2013
For cattle (Bos taurus), age estimations using dental criteria before the eruption of the first molar (3-8months) have large error margins. This hampers archaeozoological investigation into perinatal mortality or the putative slaughtering of very young calves for milk exploitation. Previous ageing methods for subjuveniles have focused on the length of unfused bones, but it is rarely possible to use them because they are restricted to foetuses and because of the fragmentation of bones. This paper presents new age prediction models based on length, breadth and depth of post cranial bones produced from a dataset of modern calves (n=27). This reference collection was compiled from material of k…
Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM …
2020
Abstract Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pre…
Pregnancy and periodontal disease: does exist a two-way relationship?
2017
Periodontal disease (PD) is an inflammatory disease of the tissues supporting the teeth. PD affects 65 million adults over the age of 30 years in the USA, and worldwide 5 to 70% of adults. Women who develop PD during pregnancy, itâs estimated 1 woman in 5, may have a higher risk of adverse pregnancy outcomes. PD during pregnancy starts by dental plaque and is increased by the action of pregnancy hormones. In order to study the effect of PD on adverse pregnancy outcomes, we have performed this narrative review summarising the current studies about the influence of PD on pregnancy. Periodontal pockets are a reservoir of oral microbiota. Modifications in oral microbiota may be considered as …
Zīdaiņu mirstības atšķirības Baltijas reģionā - Latvijā, Igaunijā, Lietuvā saistībā ar makroekonomiskajiem faktoriem no 2010. līdz 2016. gadam
2020
Tēmas pamatojums: Zīdaiņu un bērnu līdz 5 mirstība ir viens no galvenajiem valstu un bērnu labklājības rādītājiem, kas joprojām ir augsti pat vairākās attīstītās valstīs. Šī iemesla dēļ ir svarīgi monitorēt veicinošos faktorus, kas rada bērnu mirstības riskus agrīnā vecumā reģionālā perspektīvā, lai varētu tos mazināt un novērst. i,. Pētījumu sērija, ko veica LU MF Pediatrijas katedra Valsts pētījumu programmas ietvaros (1996 – 2010), identificēja cēloņsakarības starp bērnu mirstību un atsevišķiem socio- un makro-ekonomiskiem faktoriem Baltijas valstīs un atklāja atšķirības to savstarpējā mijiedarbā Latvijā, salīdzinājumā ar Lietuvu un Igauniju.
