Despite the high frequency of gastrointestinal complications and opportunistic infections in HIV-1 infected patients, tracheoesophageal (TEF) and bronchoesophageal (BEF) fístulas are rare. Our objective is to comunicate an additional and unusual case of TEF in an HIV-1-infected patient whose immunologic status was good with complete suppression of viral replication, so although uncommon, TEF/BEF of an infectious origen should be considered in AIDS. Endoscopic treatment with tracheal/esophageal stents is not without morbidity and mortality...

BACKGROUND: Dietary management of phenylketonuria (PKU) requires the replacement of natural protein-containing foods with special low protein foods. The effect of a PKU type diet on factors contributing to energy balance requires investigation. OBJECTIVE: To investigate the impact of a PKU type meal on appetite ratings, gut appetite hormones, thermic effect of feeding (TEF) and fat oxidation. METHODS: Twenty-three healthy adults (mean ± SD age: 24...

Aim The aim of this study was to evaluate the results of Swallowing Rehabilitation Protocol (SRP) on swallowing function (SF) of esophageal atresia and tracheoesophageal fistula (EA-TEF) patients with pharyngeal swallowing disorder. Materials and Methods In this study, 24 children with EA-TEF who had deglutitive and respiratory problems were grouped into either study (n = 12) or control group (n = 12) by basic randomization. Study group received the SRP including neuromuscular electrical stimulation, thermal tactile stimulation, and hyolaryngeal mobilization...

Recent research has proposed that GIT2 (G protein-coupled receptor kinase interacting protein 2) acts as an integrator of the aging process through regulation of 'neurometabolic' integrity. One of the commonly accepted hallmarks of the aging process is thymic involution. At a relatively young age, 12 months old, GIT2(-/-) mice present a prematurely distorted thymic structure and dysfunction compared to age-matched 12 month-old wild-type control (C57BL/6) mice. Disruption of thymic structure in GIT2(-/-) (GIT2KO) mice was associated with a significant reduction in the expression of the cortical thymic marker, Troma-I (cytokeratin 8)...

OBJECTIVES: Patients with esophageal atresia/tracheo-esophageal fistula (EA-TEF) can develop Barrett's esophagus as a long-term consequence of their condition. Intestinal metaplasia (IM), a risk factor for developing adenocarcinoma of the esophagus, has not been well characterized in the pediatric population. METHODS: Retrospective review of EA-TEF patients followed at three academic pediatric centers between the years 1997 and 2014. RESULTS: Among 542 children and adolescents, 1...

Paralytic shellfish poisoning results from consumption of seafood naturally contaminated by saxitoxin and its congeners, the paralytic shellfish toxins (PSTs). The levels of such toxins are regulated internationally, and maximum permitted concentrations in seafood have been established in many countries. A mouse bioassay is an approved method for estimating the levels of PSTs in seafood, but this is now being superseded in many countries by instrumental methods of analysis. Such analyses provide data on the levels of many PSTs in seafood, but for risk assessment, knowledge of the relative toxicities of the congeners is required...

Ingestion of shellfish with dinophysistoxin-2 (DTX2) can lead to diarrheic shellfish poisoning (DSP). The official control method of DSP toxins in seafood is the liquid chromatography-mass spectrometry analysis (LC-MS). However in order to calculate the total toxicity of shellfish, the concentration of each compound must be multiplied by individual Toxicity Equivalency Factor (TEF). Considering that TEFs caused some controversy and the scarce information about DTX2 toxicity, the aim of this study was to characterize the oral toxicity of DTX2 in mice...

BACKGROUND: The yeast Yarrowia lipolytica is an increasingly common biofactory. To enhance protein expression, several promoters have been developed, including the constitutive TEF promoter, the inducible POX2 promotor, and the hybrid hp4d promoter. Recently, new hp4d-inspired promoters have been created that couple various numbers of UAS1 tandem elements with the minimal LEU2 promoter or the TEF promoter. Three different protein-secretion signaling sequences can be used: preLip2, preXpr2, and preSuc2...

DNA oxidation damage has been regarded as one of the possible mechanisms for the hepatic carcinogenesis of dioxin-like compounds (DLCs). In this study, we evaluated the toxic equivalency factor (TEF) from the standpoint of induced DNA oxidation products and their relationship to toxicity and carcinogenicity. Nine DNA oxidation products were analyzed in the liver of female Sprague-Dawley rats exposed to 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD) alone or the tertiary mixture of TCDD, 3,3',4,4',5-pentachlorobiphenyl (PCB 126), and 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) by gavage for 14, 31, and 53 weeks (5 days/week) by LC-MS/MS: 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dGuo); 1,N(6)-etheno-2'-deoxyadenosine (1,N(6)-εdAdo); N(2),3-ethenoguanine (N(2),3-εG); 7-(2-oxoethly)guanine (7-OEG); 1,N(2)-etheno-2'-deoxyguanosine (1,N(2)-εdGuo); malondialdehyde (M1dGuo); acrolein (AcrdGuo); crotonaldehyde (CrdGuo); and 4-hydroxynonenal (HNEdGuo) derived 2'-deoxyguanosine adducts...

RATIONALE: Stable isotope ratios of carbon and nitrogen are valuable tools for field ecologists to use to analyse animal diets. However, the application of these tools requires knowledge of the tissue enrichment factor (TEF) and half-life (HL). We experimentally compared TEF and HL in two freshwater fish larvae. We hypothesised that chub had a better growth/tissue replacement ratio than roach, due to the use of a food closer to their natural diet. METHODS: We determined the isotopic HL, the TEF and the contribution of growth or metabolic tissue replacement to dynamic isotopic incorporation...

RNA polymerase II (Pol2) movement through chromatin and the co-transcriptional processing and fate of nascent transcripts is coordinated by transcription elongation factors (TEFs) such as polymerase-associated factor 1 (Paf1), but it is not known whether TEFs have gene-specific functions. Using strand-specific nucleotide resolution techniques, we show that levels of Paf1 on Pol2 vary between genes, are controlled dynamically by environmental factors via promoters, and reflect levels of processing and export factors on the encoded transcript...

PURPOSE: We compared the postnatal course, morbidity and early results after repair for cases of isolated or "pure" TEF with those for cases of esophageal atresia (EA) with distal tracheoesophageal fistula (TEF). METHODS: Twenty-four consecutive infants were divided into two groups: isolated TEF [TEF group] (n = 5) and EA with distal TEF [EA group] (n = 19). RESULTS: A high rate of prematurity (29%) and major cardiac and other surgically-relevant malformations (0...

Foreign body (FB) ingestion is a common problem in children. Prolonged impaction of FB in esophagus may result in tracheoesophageal fistula (TEF). A 6-year-old girl presented with progressive dysphagia and recurrent chest infections. No history of FB ingestion was given by parents. Further investigations revealed FB (spool) in cervical esophagus. Patient was successfully managed by surgery through trans-cervical approach.

REVIEW
Arunjot Singh, William Middlesworth, Julie Khlevner
PURPOSE OF REVIEW: Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a congenital aerodigestive anomaly with high survival rates after surgical repair. Care should now be focused on prevention of long-term complications using appropriate surveillance techniques. RECENT FINDINGS: The incidence of gastroesophageal reflux disease (GERD) is high in patients with EA/TEF. Consequences of untreated GERD include esophagitis, strictures, and Barrett esophagus. Subjective symptoms are an unreliable indicator of presence or severity of GERD, and therefore, diagnostic testing is needed to assess esophageal heath and monitor the effectiveness of anti-reflux treatment...

Tissue integrity and homeostasis are accomplished through strict spatial and temporal regulation of cell growth and proliferation during development. Various signaling pathways have emerged as major growth regulators across metazoans; yet, how differential growth within a tissue is spatiotemporally coordinated remains largely unclear. Here, we report a role of a growth modulator Yorkie (Yki), the Drosophila homolog of Yes-associated protein (YAP), that differentially regulates its targets in Drosophila wing imaginal discs; whereby Yki interacts with its transcriptional partner, Scalloped (Sd), the homolog of the TEAD/TEF family transcription factor in mammals, to control an essential cell cycle regulator Cyclin E (CycE)...
