Deconstructing stereotypes: Stature, match-playing time, and performance in elite Women's World Cup soccer

Recruiting companies recommend elite female soccer players be ≥165 cm (5'5″) in stature. This study investigated if stature limits match-playing time and performance in elite World Cup soccer among players, positions, and countries. We hypothesized stature would not affect match-playing time or performance. Descriptive data were collected on 552 players from 2019 FIFA Women's World Cup. Odds ratios determined likelihood of starting for players <165 cm and ≥165 cm. ANOVAs compared playing time between stature groups, among positions, and between countries. Performance factors including assists, goals, attempts, corners, shots blocked, and defending blocks were reported. Independent t-tests compared differences between players (≥165 cm, < 165 cm). Data are reported, mean difference [95% confidence interval] [MD (95%CI)] and effect sizes (ES). On average, 32.3% of players were <165 cm. Of total players, no differences existed in total minutes (F = 0.98, p = 0.32), matches (F = 0.27 p = 0.59), or average minutes per match (F = 0.48, p = 0.49) between stature groups, regardless of position. No differences existed in playing time between players <165 cm and ≥165 cm among any positions (p > 0.05), or between countries (p > 0.05). Taller mid-fielders exhibited greater performance in goals, assists, attempts, shots blocked, and defending blocks (MD [95%CI] ES; assists, -0.44[-0.76,-0.11]0.59, p = 0.009; goals, -0.35[-0.69,-0.01]0.44, p = 0.047); attempts, 3.14[1.38, 4.90]0.80, p = 0.001; corners, 2.04[0.12, 3.95]0.48, p = 0.037; shots blocked, 0.96[0.40, 1.51]0.75, p = 0.001; defending blocks, 0.43[0.32,0.82]0.48, p = 0.035), however, actual differences were minimal. Our findings indicate stature does not inhibit playing and performing elite women's soccer, as nearly one-third of players were <165 cm.

Labial adhesions secondary to postpartum vulvar edema. A report of two cases

Labial adhesions have been found commonly in children. Two patients developed thick labial adhesions secondary to massive postpartum vulvar edema.

The clinical significance of low maternal serum alpha-fetoprotein

Lowered maternal serum alpha-fetoprotein was retrospectively investigated in 20,000 patients who underwent prenatal maternal serum alpha-fetoprotein screening. Two hundred thirty-two patients were initially evaluated as having maternal serum alpha-fetoprotein levels less than 0.25 multiple of the normal median. Correction factors, such as incorrect estimation of gestational age, reduced to 180 the number of patients with low alpha-fetoprotein. In this target group, patients with known pregnancy outcomes sustained a fetal loss in 38% of the cases. It appears that significantly low maternal serum alpha-fetoprotein is associated with a dramatic increase in second-trimester fetal wastage.
