Background
Studies have reported mixed findings regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on pregnant women and birth outcomes. This study used a quasi-experimental design to account for potential confounding by sociodemographic characteristics.
MethodsData were drawn from 16 prenatal cohorts participating in the Environmental influences on Child Health Outcomes (ECHO) program. Women exposed to the pandemic (delivered between 12 March 2020 and 30 May 2021) (n = 501) were propensity-score matched on maternal age, race and ethnicity, and child assigned sex at birth with 501 women who delivered before 11 March 2020. Participants reported on perceived stress, depressive symptoms, sedentary behavior, and emotional support during pregnancy. Infant gestational age (GA) at birth and birthweight were gathered from medical record abstraction or maternal report.
ResultsAfter adjusting for propensity matching and covariates (maternal education, public assistance, employment status, prepregnancy body mass index), results showed a small effect of pandemic exposure on shorter GA at birth, but no effect on birthweight adjusted for GA. Women who were pregnant during the pandemic reported higher levels of prenatal stress and depressive symptoms, but neither mediated the association between pandemic exposure and GA. Sedentary behavior and emotional support were each associated with prenatal stress and depressive symptoms in opposite directions, but no moderation effects were revealed.
ConclusionsThere was no strong evidence for an association between pandemic exposure and adverse birth outcomes. Furthermore, results highlight the importance of reducing maternal sedentary behavior and encouraging emotional support for optimizing maternal health regardless of pandemic conditions.

Acute doses of Ca rapidly increase serum Ca and reduce bone resorption concomitant with a reduction in serum parathyroid hormone (PTH) levels. The physiological response to a dose of Ca in milk and to a Ca salt may be different. The present study investigated Ca absorption patterns with increasing levels of fortification in milk, and the response to one dose of a Ca salt. A group of twenty-eight Asian women aged 20–45 years volunteered to attend the laboratory over several weeks. The fasted volunteers were randomised to one of three experimental drinks: 200 ml skimmed milk containing 250, 500 or 1000 mg Ca. A subgroup of seven volunteers also received a calcium gluconate/carbonate salt containing 1000 mg Ca in 200 ml water. Serial blood samples and urine were collected for 5 h from baseline. Different doses of Ca in milk resulted in a graded response in serum corrected Ca, PTH and C-telopeptide of type I collagen (CTx) but not ionised Ca. Serum Ca increased in response to all milk drinks and from 2 to 5 h the blood Ca levels were significantly different for the 250 and 1000 mg doses, as was the integrated response between the loads. The PTH response to the two higher doses was significantly more than following the 250 mg dose. The integrated response for CTx and urinary Ca between all three doses of Ca in milk was significantly different. A dose of Ca salt elicited a more immediate response reaching a plateau faster, and declining faster to baseline. Fortified milk is a safe matrix for delivering larger doses of Ca.

1. The Speeton Clay of Yorkshire contains abundant Foraminifera in the beds named by Mr. Lamplugh B (base), C10, and C2; but the specimens examined from the other subdivisions of F, E, D, and C either do not contain any Foraminifera or they are present in small numbers only.
2. Two new species, Cristellaria chapmani, Pulvinulina lamplughi, and a new variety, Lagena apiculata, var. danfordi, occur and are described. Forty-four species belonging to sixteen genera have been found.
3. The characteristic of the Foraminiferal fauna of the Speeton Clay is the great predominance of Pulvinulina caracolla (Roemer) over all other species.
4. Twenty-five per cent of the species of Foraminifera occur also in the Hils of North Germany, 35 per cent in the Red Chalk of Speeton, 40 per cent in the Bargate Beds of Surrey, and 58·5 per cent in the Gault of Folkestone.
5. Dimorphism is clearly shown by P. caracolla (Roemer). Previously it has been stated to occur among the Pulvinulinæ in P. partschiana, d'Orb., but no case has been described.
6. Notes are given on the microscopical characters of the sediments.

The Speeton Clay of Yorkshire is of considerable interest, as it is the chief marine representative of the Lower Cretaceous formations in England. It has been the subject of important papers by Professor J. W. Judd, F.R.S., and Mr. G. W. Lamplugh, F.R.S., while the palæontology of the Cephalopoda and Lamellibranchiata has been respectively worked out by Professor A. P. Pavlow and Mr. H. Woods. Mr. C. G. Danford has also contributed to our knowledge of the beds. The Microzoa, however, have never been examined, and the present paper gives the results of an investigation of the Foraminifera of the deposit.

In the almost complete absence of fossils in the British Keuper there has been a lack of datum-lines in that formation by which we may compare the horizons of different sections. Yet in such a thick and widely spread deposit it is very desirable to have subdivisions enabling us to give the particular part of the Keuper to which a section belongs. In deposits such as the New Red formations too great stress has been laid on lithology, inevitable perhaps in the scarcity of fossils, but a source of grave errors in correlation. For example, Mr. L. J. Wills thinks that fossils found in the Keuper of Warwick have affinity, not with the Keuper, but with the Muschelkalk of Germany. Again, there are strata in the Permo-Bunter of Nottinghamshire which might be mistaken for Keuper Waterstones, if only lithology was considered. Over small areas a band of sandstone with some peculiarities may be used as a datum-line, as in the Arden district of Warwickshire and in Nottinghamshire, but these are of local value only.

Up to the present marine fossils have been recorded in Middle Coal-measures in the South Lancashire Coal-field at two horizons only. They are (1) in the banks of the Tame, near Ashtonunder-Lyne, found by Professor A. H. Green, and at Ashton Moss Colliery, about 750 feet above the Great Mine, discovered by the late George Wild. (2) Mr. H. Bolton, F.R.S.E., informs me that the Californian or Thin Bed of Fulledge Colliery, Burnley, which is 410 feet above the Arley Mine, is a marine horizon.
