We reported transcatheter closure of gigantic persistent ductus arteriosus (PDA) complicated by severe pulmonary hypertension (PH) using a custom-made PDA occluder. A 19-year-old lady weighing 45 kg visited to our Heart Saving Project in Mongolia with a chief complaint of shortness of breath. Contrast CT scan showed ellipsoidal section of PDA whose long axis being 28 mm, and the short axis of 21 mm. A custom-made PDA occluder, whose retention skirt, the aortic side, and the pulmonic side diameter of the body were 54, 36, 34 mm, respectively, was successfully deployed using 14-Fr sheath. Pulmonary pressure decreased around a half compared to before closure. A custom-made duct occluder could be a reasonable and cost-effective choice for transcatheter closure of gigantic PDA complicated by severe PH. © 2015 Wiley Periodicals, Inc. Source

Preeclampsia affects ∼3%-7% of all pregnancies and is the third leading cause of maternal mortality globally. Growing evidence indicates that preeclampsia results from vascular dysfunction, which also increases the risk for future cardiovascular events. Until recently, preeclampsia was considered a disorder limited to pregnancy, which fully resolved with the delivery of the placenta; however, it is now clear that women with a history of preeclampsia have approximately double the risk of future cardiovascular events compared to women with normotensive pregnancies. The aims of this review were to describe the hemodynamic and vascular changes that occur in normal and preeclamptic pregnancies, to review noninvasive methods to test vascular function, and to discuss the associated increased cardiovascular disease risk related to preeclampsia. © Mary Ann Liebert, Inc. 2016.

Background: For 20 years, China has participated in 267 international cooperation projects against the HIV/AIDS epidemic and received ~526 million USD from over 40 international organizations. These projects have played an important role by complementing national efforts in the fight against HIV/AIDS in China. Methods: The diverse characteristics of these projects followed three phases over 20 years. Initially, stand-alone projects provided technical support in surveillance, training or advocacy for public awareness. As the epidemic spread across China, projects became a part of the comprehensive and integrated national response. Currently, international best practices encourage the inclusion of civil society and non-governmental organizations in an expanded response to the epidemic. Results: Funding from international projects has accounted for one-third of the resources provided for the HIV/AIDS response in China. Beyond this strong financial support, these programmes have introduced best practices, accelerated the introduction of AIDS policies, strengthened capacity, improved the development of grassroots social organizations and established a platform for communication and experience sharing with the international community. However, there are still challenges ahead, including integrating existing resources and exploring new programme models. The National Centre for AIDS/STD Control and Prevention (NCAIDS) in China is consolidating all international projects into national HIV prevention, treatment and care activities. Conclusion: International cooperation projects have been an invaluable component of China's response to HIV/AIDS, and China has now been able to take this information and share its experiences with other countries with the help of these same international programmes. © The Author 2010; all rights reserved.

Mitochondrial fatty acid oxidation (FAO) disorders are caused by defects in one of the FAO enzymes that regulates cellular uptake of fatty acids and free carnitine. An in vitro probe acylcarnitine (IVP) assay using cultured cells and tandem mass spectrometry is a tool to diagnose enzyme defects linked to most FAO disorders. Extracellular acylcarnitine (AC) profiling detects carnitine palmitoyltransferase-2, carnitine acylcarnitine translocase, and other FAO deficiencies. However, the diagnosis of primary carnitine deficiency (PCD) or carnitine palmitoyltransferase-1 (CPT1) deficiency using the conventional IVP assay has been hampered by the presence of a large amount of free carnitine (C0), a key molecule deregulated by these deficiencies. In the present study, we developed a novel IVP assay for the diagnosis of PCD and CPT1 deficiency by analyzing intracellular ACs. When exogenous C0 was reduced, intracellular C0 and total AC in these deficiencies showed specific profiles clearly distinguishable from other FAO disorders and control cells. Also, the ratio of intracellular to extracellular C0 levels showed a significant difference in cells with these deficiencies compared with control. Hence, intracellular AC profiling using the IVP assay under reduced C0 conditions is a useful method for diagnosing PCD or CPT1 deficiency. © 2012 Springer-Verlag Berlin Heidelberg. Source

Background:Cystic echinococcosis (CE) is a globally distributed cestode zoonosis that causes hepatic cysts. Although Echinococcus granulosus sensu stricto (s.s.) is the major causative agent of CE worldwide, recent molecular epidemiological studies have revealed that E. canadensis is common in countries where camels are present. One such country is Mongolia.Methodology/Principal Findings:Forty-three human hepatic CE cases that were confirmed histopathologically at the National Center of Pathology (NCP) in Ulaanbaatar (UB) were identified by analysis of mitochondrial cox 1 gene as being caused by either E. canadensis (n = 31, 72.1%) or E. granulosus s.s. (n = 12, 27.9%). The majority of the E. canadensis cases were strain G6/7 (29/31, 93.5%). Twenty three haplotypes were identified. Sixteen of 39 CE cases with data on age, sex and province of residence were citizens of UB (41.0%), with 13 of the 16 cases from UB caused by E. canadensis (G6/7) (81.3%). Among these 13 cases, nine were children (69.2%). All pediatric cases (n = 18) were due to E. canadensis with 17 of the 18 cases (94.4%) due to strain G6/7. Serum samples were available for 31 of the 43 CE cases, with 22 (71.0%) samples positive by ELISA to recombinant Antigen B8/1 (rAgB). Nine of 10 CE cases caused by E. granulosus s.s. (90.0%) and 13 of 20 CE cases by E. canadensis (G6/7) (65.0%) were seropositive. The one CE case caused by E. canadensis (G10) was seronegative. CE cases caused by E. granulosus s.s. showed higher absorbance values (median value 1.131) than those caused by E. canadensis (G6/7) (median value 0.106) (p = 0.0137).Conclusion/Significance:The main species/strains in the study population were E. canadenis and E. granulossus s.s. with E. canadensis the predominant species identified in children. The reason why E. canadensis appears to be so common in children is unknown. © 2014 Ito et al. Source
