Background: The ideal time to operate on pectus excavatum (PE) using the Nuss procedure (NP) is between 12 and 18 years of age, because it is more difficult to bend the sternum of older patients and they have more pain and complications. The authors present a prospective study of adult patients with PE operated on by NP, analyzing technical improvements, new tricks, bar modifications, and preliminary outcomes.
Materials And Methods: From May 2003 to September 2009, 19 patients presenting PE (group 1), aged 20-27 years, underwent NP. A modified operation was performed in 10 patients using the scope at the axilla; the bar needed hyperconvex modeling in the middle and extended internal curving of its extremities before rotation at the thorax. A new and more resistant bar was designed and was used in the last 5 patients. Two stabilizers were implanted in 11 cases. Group 1 patients were compared with a group of 26 teenagers operated on before 20 years of age (group 2) during the same period.
Results: All operations could be performed despite the more intense rigidity of the anterior thoracic wall in group 1. It was easier in the last patients who received thicker bars. After the third postoperative day, the operations were more painful in group 1, requiring more potent analgesic drugs. However, the adults were more tolerant and complained less than most patients of group 2. There were no differences between the two groups in operative times, complications, or hospitalization.
Conclusions: Patients with PE can be operated on during the third decade of life by the NP, facilitated by compensating bending of the bar, a stronger bar, and the use of potent analgesics, leading to outcomes similar to those in younger patients.

Purpose: Noonan syndrome and related disorders (NS) are multisystemic conditions affecting approximately 1:1000 individuals. Previous natural history studies were conducted prior to widespread comprehensive genetic testing. This study provides updated longitudinal natural history data in participants with molecularly confirmed NS.

Background: We still know little about the effective pharmacological treatment of heart failure (HF) associated with the Fontan circulation. One of the new options may be sodium glucose cotransporter-2 inhibitors (SGLT2i), which have been proven effective in classic forms of left ventricular HF.
Objectives: To evaluate the effect and safety of SGLT2i inclusion in adults with Fontan circulation.
Lateralization of Neural Speech Discrimination at Birth Is a Predictor for Later Language Development.
Dev Sci

Department of Pediatrics and Adolescent Medicine, Comprehensive Center for Pediatrics, Medical University of Vienna, Vienna, Austria.
Newborns are able to neurally discriminate between speech and nonspeech right after birth. To date it remains unknown whether this early speech discrimination and the underlying neural language network is associated with later language development. Preterm-born children are an interesting cohort to investigate this relationship, as previous studies have shown that preterm-born neonates exhibit alterations of speech processing and have a greater risk of later language deficits.

The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Newtown, Australia (L.C., S.Y., N.E., M.W., T.L., Y.G., C.S.A., K.H., X.C., R.P.).
Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.
Determinants of Racial and Ethnic Differences in Maternal Cardiovascular Health in Early Pregnancy.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
