A clinical "parent-specific" method for evaluating recumbent length and stature of children, allowing for the stature of parents, is presented. This method uses midparent stature and allows adjustment of recumbent length (birth to 3 years) and stature (3 to 18 years) of US children relative to National Center for Health Statistics growth charts. The method is based on parent-child relationships for 586 midparent-child pairs participating in the Fels Longitudinal Study, and on more than 16,000 serial measurements of recumbent length and stature. The method provides a clinical tool to separate the normal genetic contribution of parental stature to stature of children from other factors that affect stature such as malnutrition or disease.

A breast-fed 4-month-old infant girl observed since birth had gained only 1230 g (2 lb 11 oz). The mother had three older children with birth weights of 3440 g (7 lb 9 oz), 4000 g (8 lb 13 oz), and 4895 g (10 lb 13 oz). All were exclusively breast-fed and thrived, eventually growing between the 25th and 50th percentiles on the National Center for Health Statistics growth charts. The mother also had five miscarriages during these 7 years. She had gastric bypass surgery for morbid obesity between her third and fourth children. She had lost 49 kg (109 lb) (114 kg to 65 kg) [254 lb to 145 lb]) in the first 12 months after surgery and had been stable at her new weight for 4 months prior to becoming pregnant with this baby.

Abstract Background Cerebral autoregulation (CAR) systems maintain blood flow to the brain across a wide range of blood pressures. Deficits in CAR have been linked to gait speed but previous studies had small sample sizes and used specialised equipment which impede clinical translation. The purpose of this work was to assess the association between gait speed and orthostatic cerebral oxygenation in a large, community-dwelling sample of older adults. Methods Data for this study came from the Irish Longitudinal Study on Ageing. A near infrared spectroscopy (NIRS) device attached to the forehead of each participant (n=2708) was used to track tissue saturation index (TSI; the ratio of oxygenated to total haemoglobin) during standing. Gait speed (GS) was assessed using a portable walkway. Results Recovery was impaired in slower GS participants with a TSI value at 20 seconds (after standing) of -0.55% (95% CI: -0.67, -0.42) below baseline in the slowest GS quartile versus -0.14% (95% CI: -0.25, -0.04) in the fastest quartile. Slower GS predicted a lower TSI throughout the 3-minute monitoring period. Results were not substantially altered by adjusting for orthostatic hypotension. Adjustment for clinical and demographic covariates attenuated the association between but differences remained between GS quartiles from 20 seconds to 3 minutes after standing. Conclusion This study reported evidence for impaired recovery of orthostatic cerebral oxygenation depending on gait speed in community-dwelling older adults. Future work assessing NIRS as a clinical tool for monitoring the relationship between gait speed and cerebral regulation is warranted.

Few longitudinal studies examine how changes in parent–child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict youth internalizing problems in Grade 9 ( N = 618) and whether these linkages differ for boys and girls. Developmental trends (greater decreases in warmth and increases in hostility) were associated with more youth internalizing problems. Greater year-to-year lability (more fluctuations) in father hostility and warmth were also associated with more internalizing problems. Greater lability in mother warmth was associated with more internalizing problems for girls only. The strongest effects of lability on internalizing problems were found for youth with the highest lability scores. This study underscores the importance of differentiating developmental trends from lability in parent–child relationships, both of which may be important for youth internalizing problems.
