The impact of prenatal diagnosis (PreND) for congenital heart disease on outcomes after neonatal open heart surgery is undetermined. We hypothesized that PreND has a positive impact on surgical outcomes in terms of immediate postnatal intensive care, which may lead to a decreased risk of persistent shock before surgery.

Among the 949 neonates who underwent open heart surgery between January 2002 and December 2017, 655 patients (69.0%) were diagnosed prenatally (Group-PreND) and 294 patients (31.0%) were diagnosed postnatally (Group-PostND). Procedural complexity, incidence of postnatal shock (Serum lactate >4.0 mmol/L or pH <7.2), hospitalization timing, duration of shock, resolution of shock, and in-hospital mortality were compared between the two groups.

In Group-PreND, procedure-dependent comprehensive Aristotle score (10.8 vs. 10.0 P < .001), incidence of extra-cardiac anomalies (13.0% vs. 7.1%, P = .008), heterotaxy syndrome (3.8% vs. 1.0%, P = .021), and postnatal shock (244/655, 37.3% vs. 78/294, 26.5%, P = .001) were higher than in Group-postND. However, patients in Group-PreND were hospitalized earlier after birth (0 day vs 5 days, P < .001), experiencing shorter duration of shock (5.3 hours vs 9.0 hours, P = .01), and, consequently, showing higher incidence of shock resolution (212/244, 87% vs. 52/78, 67%, P < .001). In-hospital mortality was comparable between the two groups (P = .070).

Postnatal shock is more frequently observed in Group-PreND. However, prenatal awareness of the disease leads to immediate postnatal initiation of intensive care with shorter exposure to shock, leading to higher probability of shock resolution.

This study investigated a two-stage arterial switch operation (ASO) to treat transposition of the great arteries with intact ventricular septum (TGA-IVS) in late referral patients.

From February 2007 to August 2018, we retrospectively analyzed patients with TGA-IVS or TGA with restricted ventricular septal defects who had undergone two-stage ASO at our institution. Forty-one patients were included 21 (51.2%) who had undergone long-term two-stage ASO and 20 (48.8%) who had undergone rapid two-stage ASO.

The long-term two-stage group was older at ASO (3.5 versus 25 months; p < 0.001). The intensive care unit time, mechanical ventilation time, and length of stay were more satisfactory in the long-term group than in the rapid group (P=0.004, P=0.004, and P=0.007, respectively). No in-hospital mortality occurred in the long-term group, and the postoperative course was more manageable in the long-term group than in the rapid group. However, the risk of significant neoaortic regurgitation was lower in the rapid group, which also had a better left ventricular ejection fraction.

The long-term group achieved better early-term outcomes than the rapid group. However, a high risk of neoaortic regurgitation and myocardial dysfunction was also noted.

The FTO gene has one of the strongest links with obesity and high body mass index (BMI) in humans. Besides, this gene is highly expressed in the brain, may play a role in the nervous system, and could confer risk for depression, although scarce literature is available in this respect. We perform a systematic review of the relationship between FTO and both conditions. We selected original articles with observational design or reviews, where depression was assessed with ICD-10, DSM-5 or previous versions, published from 2012 (when the first related paper was published) to November 2020, performed in adults, in English or Spanish and having an optimal methodological quality (evaluated with SIGN checklist). Five original studies were finally included. The results regarding the role of FTO in depression-obesity comorbidity were inconclusive. This leads us to endorse further research covering the role of this gene on both conditions, emphasising a more precise characterization of depression, in order to confirm this role.The physiological effects of the endogenously generated hydrogen sulfide (H2S) have been extensively studied in recent years. This review summarized the role of H2S in the origin of life and H2S metabolism in organisms from bacteria to vertebrates, examined the relationship between H2S and oxygen from an evolutionary perspective and emphasized the oxygen-dependent manner of H2S signaling in various physiological and pathological processes. H2S and oxygen are inextricably linked in various cellular functions. H2S is involved in aerobic respiration and stimulates oxidative phosphorylation and ATP production within the cell. Besides, H2S has protective effects on ischemia and reperfusion injury in several organs by acting as an oxygen sensor. Also, emerging evidence suggests the role of H2S is in an oxygen-dependent manner. All these findings indicate the subtle relationship between H2S and oxygen and further explain why H2S, a toxic molecule thriving in an anoxia environment several billion years ago, still affects homeostasis today despite the very low content in the body.Glycosynthases are glycoside hydrolase mutants that can synthesize oligosaccharides or glycosides from an inverted donor without hydrolysis of the products. Although glycosynthases have been characterized from a variety of glycoside hydrolase (GH) families, family GH116 glycosynthases have yet to be reported. We produced the Thermoanaerobacterium xylanolyticum TxGH116 nucleophile mutants E441D, E441G, E441Q and E441S and compared their glycosynthase activities to the previously generated E441A mutant. The TxGH116 E441G and E441S mutants exhibited highest glycosynthase activity to transfer glucose from α-fluoroglucoside (α-GlcF) to cellobiose acceptor, while E441D had low but significant activity as well. The E441G, E441S and E441A variants showed broad specificity for α-glycosyl fluoride donors and p-nitrophenyl glycoside acceptors. The structure of the TxGH116 E441A mutant with α-GlcF provided the donor substrate complex, while soaking of the TxGH116 E441G mutant with α-GlcF resulted in cellooligosaccharides extending from the +1 subsite out of the active site, with glycerol in the -1 subsite.
