The risk of the combined outcome of neonatal or stillbirth loss of life was 1.7 percent in the postsurgery group and 0.7 percent in the control group . There was no significant between-group difference in the frequency of congenital malformations . Subgroup Analyses In the four interaction tests, we found no significant effect modification of bariatric surgery on gestational diabetes according to presurgery BMI, the interval from surgery to delivery, or the magnitude of decrease in BMI from presurgery to early pregnancy or regarding to parity . There is also no significant effect modification of bariatric medical procedures on perinatal outcomes, except in 3 of the 16 interaction testing, which yielded the next significant interactions: a greater decrease in BMI was associated with a lower threat of large-for-gestational-age infants and a higher risk of preterm birth, and a longer surgery-to-delivery interval was associated with a higher risk of small-for-gestational-age infants .Witt of the University Medical Center in Berlin, Germany, and her team examined the use of acupuncture as an extension of routine medical care and whether the effects of treatment last after therapy is certainly discontinued. The group involved a total of 3,553 patients split into three groups: 322 instantly received up to 15 sessions of acupuncture in the original three month period; 310 controls received no acupuncture for the initial three months; and 2,921 received the same treatment as the acupuncture group.
