Selective arterial shunting increased the caliber of the LPA from 4.1 mm (1.2-5.6) to 6.5 mm (1.7-11.9) and this increase was preserved post-Fontan (6.7 mm [1.3-8.0]) (median [range]). Relacorilant concentration Ventricular end diastolic pressure increased with arterial shunting but resolved after shunt takedown and Fontan completion (median +3 and -4 mm Hg respectively). Post-Fontan hospital length of stay was not prolonged (median 11 days, range 7-14). No deaths occurred. In univentricular hearts and PA hypoplasia, selective systemic-PA shunting physiologically increases the caliber of the distal vessels. In selected patients this can be done safely with maintenance of PA growth and resolution of the elevated end diastolic pressure with Fontan completion.Some patients show high serum carcinoembryonic antigen (CEA) levels in the evaluation of candidate patients for lung transplantation, which might be a challenge because high serum CEA potentially implies an existence of malignancy. For further understanding of the true meaning of high serum CEA levels in lung transplantation, we retrospectively investigated the relationship between serum CEA and clinical data. We also performed immunohistochemical analysis of explanted native lungs and evaluated its relationship with serum CEA levels. Retrospective chart review was performed in consecutive patients who underwent lung transplantation with measurement of serum CEA before and after transplantation at our institution between August 2008 and June 2017. Histopathological analysis was also performed in the same cohort of patients. Survival outcomes and pathohistological findings were compared between the high serum CEA and the normal CEA group, adjusting for potential confounding factors. One hundred and fifteen patients were eligible for analysis. High serum CEA levels before lung transplantation in most cases were decreased after the transplantation (35/39, 90%, P less then 0.001). Preoperative serum CEA levels were not associated with postoperative survival. The percentage of CEA-positive alveolar cells was significantly higher in the high serum CEA group (P less then 0.0001). After adjusting for potential confounding factors, there was a significant difference between the high serum CEA group and normal serum CEA group (CEA-positive alveolar cells; P = 0.002). High serum CEA levels before lung transplantation might derive from native lungs in the recipients and that they were not associated with overall survival after lung transplantation.Various patch materials with variable cost are used for pulmonary artery reconstruction. An analysis of reintervention based on type of patch material might inform value-based decision making. This was a retrospective review of 214 sites of pulmonary artery reconstruction at a single center from 2000 to 2014. We excluded patients with unifocalization of aortopulmonary collaterals. Primary outcome was reintervention for each type of patch. Total number of patch sites was 214 (180 patients). Median follow-up was 3.7 years. Patch materials and number of sites were branch patch homograft (92), bovine pericardium (44), autologous pericardium (41), and porcine intestinal submucosal patch (37). Median age and weight at the time of patch reconstruction were 12.1 months and 8.5 kg. Reintervention occurred at 34 sites (15.9%). With Cox proportional hazards regression, the following variables were associated with reinterevention preoperative renal failure - hazard ratio of 4.36 (1.87-10.16), P less then 0.001 and weight at surgery - hazard ratio 0.93 (0.89-0.98), P = 0.004. Patch type was not related to reintervention (P = 0.197). Cost per unit patch ranged from $0 (dollars, US) for untreated autologous pericardium to $6,105 for homograft branch patch. In this retrospective analysis, there was no relationship between type of patch used for main or central branch pulmonary artery reconstruction and subsequent reintervention on that site. This finding, combined with the widely disparate costs of patches, may help inform value-based decision making.
Ovarian torsion can occur in Van Wyk Grumbach syndrome, a disorder characterized by severe primary hypothyroidism and ovarian enlargement. To date, all documented cases of torsion in this setting describe oophorectomy, which has significant hormonal and fertility implications.

A 9-year-old pubertal girl presented to the emergency room with abdominal pain. Magnetic resonance imaging demonstrated bilateral, multi-cystic ovaries. Operative laparoscopy confirmed unilateral adnexal torsion, and detorsion without oophorectomy was accomplished. Postoperative laboratory tests revealed severe primary hypothyroidism. Ovarian size was reduced with hormone replacement therapy.

This case demonstrates that prompt interdisciplinary intervention and awareness of severe hypothyroidism as a cause of ovarian torsion related to enlarged, multi-cystic ovaries may reduce the rate of oophorectomy, allowing preservation of pediatric patients' future fertility, and reducing morbidity postoperatively through prompt, long-term thyroid supplementation.

In recent years, many drugs have been shown to have extraordinary anticancer effects. However, in a lot of cases the treatment is accompanied by undesirable side effects due to some intrinsic properties linked to the therapeutic agents, such as poor targeting selectivity and short half-life in the circulation. In this regard, extracellular vesicles (EVs), a diverse family of natural cell-derived vesicles, steal the show as potential anticancer immunotherapy or delivery vectors of anticancer agents since they are an innate mechanism of intercellular communication. Here, we describe some of the most hotly-debated issues regarding the use of EVs as anticancer therapeutics. First, we review the biology of EVs providing the most up-to-date definition of EVs as well as highlighting their circulation kinetics and homing properties. Next, we share our views on popular methods reported for EV isolation, characterization, and functional analysis.
