Where No Universal Health Care Identifier Exists: Comparison and Determination of the Utility of Score-Based Persons Matching Algorithms Using Demographic Data.

JMIR Public Health Surveill 2018 Dec 13;4(4):e10436. Epub 2018 Dec 13.

Division of Global HIV and TB, Centers for Disease Control and Prevention, Nairobi, Kenya.

Background: A universal health care identifier (UHID) facilitates the development of longitudinal medical records in health care settings where follow up and tracking of persons across health care sectors are needed. HIV case-based surveillance (CBS) entails longitudinal follow up of HIV cases from diagnosis, linkage to care and treatment, and is recommended for second generation HIV surveillance. In the absence of a UHID, records matching, linking, and deduplication may be done using score-based persons matching algorithms. Read More

ST Segment-Elevation Myocardial Ischemia After Arterial Switch Operation Due to Pericardial Drain Placement: A Case Report.

A A Pract 2018 Dec 7. Epub 2018 Dec 7.

From the Department of Anaesthesia and Intensive Care, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Myocardial ischemia postarterial switch operation has been reported extensively in the literature and has been almost exclusively ascribed to issues related to coronary artery translocation. Here, we report a case of a 5-week-old child with D-transposition of the great arteries who underwent an arterial switch operation and developed myocardial ischemia after pericardial drain placement, as evidenced by significant ST segment elevation and abnormal regional cardiac wall motion. The ST segment and cardiac wall motion improved once the drain was withdrawn from the pericardium and placed in the retrosternal space. Read More

Cancer Gene Discovery Utilizing Sleeping Beauty Transposon Mutagenesis.

Methods Mol Biol 2019 ;1907:161-170

Department of Pediatrics, University of Minnesota, Minneapolis, MN, USA.

Transposable elements are DNA sequences with the ability to move from one genomic location to another. The movement of class II transposable elements has been functionally harnessed and separated into two distinct DNA transposon components: the terminal inverted repeat sequences that flank genetic cargo to be mobilized and a transposase enzyme capable of recognizing the terminal inverted repeat sequences and catalyzing the transposition reaction. In particular, the Sleeping Beauty (SB) system was the first successful demonstration of transposon-based gene transfer in vertebrate species. Read More

Successful arterial switch operation for transposition of the great arteries with intact ventricular septum and congenital diaphragmatic hernia: A case report.

J Cardiol Cases 2014 Jul 17;10(1):39-41. Epub 2014 May 17.

Department of Cardiology, Aichi Children's Health and Medical Center, Obu, Japan.

We report performing a successful arterial switch operation on a full-term male infant with transposition of the great arteries and intact ventricular septum associated with a congenital diaphragmatic hernia. The patient developed severe persistent pulmonary hypertension after successful repair of a left congenital diaphragmatic hernia that restricted pulmonary blood flow into the hypoplastic left lung, and subsequent unilateral pulmonary congestion of the unaffected right lung occurred because of the hemodynamics generated by the transposition of the great arteries. Intravenous epoprostenol with nitric oxide inhalation and mechanical hypoventilation effectively controlled pulmonary vascular resistance before the arterial switch operation was performed.

Genome-wide patterns of transposon proliferation in an evolutionary young hybrid fish.

Mol Ecol 2018 Dec 5. Epub 2018 Dec 5.

Carl von Ossietzky University Oldenburg, Institute for Biology and Environmental Sciences, Carl von Ossietzky Str. 9-11, 26111, Oldenburg, Germany.

Hybridization can induce transposons to jump into new genomic positions, which may result in their accumulation across the genome. Alternatively, transposon copy numbers may increase through non-allelic (ectopic) homologous recombination in highly repetitive regions of the genome. The relative contribution of transposition bursts versus recombination-based mechanisms to evolutionary processes remains unclear because studies on transposon dynamics in natural systems are rare.

Better lung function with increased handgrip strength, as well as maximum oxygen uptake, in congenital heart disease across the lifespan.

Eur J Prev Cardiol 2018 Nov 30:2047487318816508. Epub 2018 Nov 30.

2 Department of Pediatric Cardiology and Congenital Heart Disease, Technical University of Munich, Germany.

Background: The respiratory benefits of muscle strength are well-known in heart-healthy populations, but recommendations and research often focus instead on aerobic fitness (peak oxygen uptake) or total activity. Independent benefits of strength thus may be underestimated, especially in congenital heart disease where perceived dangers of certain types of exercise may outweigh perceived benefits. To assess whether it is plausible that pulmonary benefits of strength in heart-healthy populations also apply in congenital heart disease, we simultaneously correlated these patients' lung function with fitness, strength, and cardiac diagnosis.

Role of transcranial sphenoidotomy in skull base surgery: classification of surgical techniques based on the surgical anatomy of the sphenoid sinus.

Authors:

J Neurosurg 2018 Nov 1:1-10. Epub 2018 Nov 1.

OBJECTIVEAlthough sphenoidotomy is more commonly performed via the transnasal approach than via the transcranial approach, transcranial sphenoidotomy (TCS) remains indispensable for en bloc resection of locally advanced sinonasal malignant tumors (SNMTs) extending to the skull base. TCS also enables transsphenoidal transposition of the temporoparietal galeal flap (TPGF) to compensate for the lack of vascularized reconstructive tissue after endoscopic transnasal skull base surgery. The objective of this study was to review the authors' surgical experience using TCS with an emphasis on the surgical anatomy of the sphenoid sinus and on the purpose of TCS. Read More

In multiply resistant Acinetobacter baumannii, complex transposons located in the chromosomal comM gene carry antibiotic and heavy metal resistance determinants. For one type, known collectively as AbaR, the ancestral form, AbaR0, entered a member of global clone 1 (GC1) in the mid 1970s and continued to evolve in situ forming many variants. In AbaR0, antibiotic and mercuric ion resistance genes are located between copies of a cadmium-zinc resistance transposon, Tn6018, and this composite transposon is in a class III transposon, Tn6019, carrying arsenate/arsenite resistance genes and five tni transposition genes.

Corrective osteotomy and in situ fusion for late-presenting nonunion of lateral condyle fractures of the humerus in adults.

J Shoulder Elbow Surg 2018 Nov 21. Epub 2018 Nov 21.

Orthopaedic and Trauma Surgery Department, Cairo University, Cairo, Egypt. Electronic address:

Background: Late presentation of lateral condylar fractures of the humerus is not an uncommon problem in children, and to lesser extent, in adults. The various surgical interventions for repairing the fracture, correcting the deformity, or even performing anterior transposition of the ulnar nerve as a single procedure or in combination, especially in adults, is still a controversial topic, with a paucity of literature regarding this. There is a risk of loss of the available preoperative range of motion, nonunion, and avascular necrosis. Read More

TETyper: a bioinformatic pipeline for classifying variation and genetic contexts of transposable elements from short-read whole-genome sequencing data.

Microb Genom 2018 Nov 22. Epub 2018 Nov 22.

5​Clinical Microbiology Laboratory, Department of Pathology, University of Virginia Health System, Charlottesville, Virginia, USA.

Much of the worldwide dissemination of antibiotic resistance has been driven by resistance gene associations with mobile genetic elements (MGEs), such as plasmids and transposons. Although increasing, our understanding of resistance spread remains relatively limited, as methods for tracking mobile resistance genes through multiple species, strains and plasmids are lacking. We have developed a bioinformatic pipeline for tracking variation within, and mobility of, specific transposable elements (TEs), such as transposons carrying antibiotic-resistance genes. Read More

Targeted deletion of rice retrotransposon Tos17 via CRISPR/Cas9.

Plant Cell Rep 2018 Nov 21. Epub 2018 Nov 21.

Plant Genome Engineering Research Unit, Division of Applied Genetics, Institute of Agrobiological Sciences, National Agriculture and Food Research Organization, 1-2 Owashi, Tsukuba, Ibaraki, 305-8634, Japan.

Key Message: A successful example of transposon deletion via CRISPR/Cas9-mediated genome editing suggests a novel alternative approach to plant breeding. Transposition of transposable elements (TEs) can affect adjacent genes, leading to changes in genetic traits. Expression levels and patterns, splicing and epigenetic status, and function of genes located in, or near, the inserted/excised locus can be affected. Read More

Transposition of Duplicated Thumb for Reconstruction of Asymmetric Radial Polydactyly.

Ann Plast Surg 2019 Jan;82(1S Suppl 1):S13-S17

From the Division of Plastic and Reconstructive Surgery, Department of Surgery, Taichung Veterans General Hospital, Taichung, Taiwan, Republic of China.

Background: In this study, we present the long-term functional and aesthetic outcomes in patients with complicated asymmetric radial polydactyly treated with this surgical technique involving the transposition of a duplicated thumb.

Methods: We evaluated 6 thumbs in 6 patients who underwent radial polydactyly reconstruction using the transposition of duplicated thumb procedure between 2001 and 2017. The procedure was used when one of the thumbs was not obviously dominant over the other, with one having a better proximal portion and the other having a better distal portion. Read More

Efficient transposition of Tn4556 by alterations in inverted repeats using a delivery vector carrying a counter-selectable marker for Streptomyces.

J Ind Microbiol Biotechnol 2018 Nov 20. Epub 2018 Nov 20.

Kitasato Institute for Life Sciences, Kitasato University, Sagamihara, Kanagawa, 252-0373, Japan.

A 6625-base pair transposon, Tn4556, was initially isolated from a Streptomyces strain and a sequence analysis was performed; however, its annotation data remain incomplete. At least three positions were identified as frameshift and base-exchange errors by resequencing. The revised sequence revealed that Tn4556 contains four open reading frames that encode transposase, methyltransferase, isoprenyl diphosphate transferase, and resolvase, respectively. Read More
