A state-of-art review on antenna designs for ingestible application.
A state-of-art review on antenna designs for ingestible application. Electromagn Biol Med. 2020 Sep 29;:1-16 Authors: Neebha TM, Andrushia AD, Durga S Abstract Research interest in ingestible Wireless Capsule Endoscopy (WCE) studies in humans showed better results than conventional invasive probe endoscopy methods. Because of the structure and the position of the small intestine, proper scanning cannot be done in the area using traditional endoscopic methods. For patient comfort, continuous developments have been suggested in capsule endoscopy designs in terms of the quality of images transmitted, capsule orientation, positioning of the capsule from outside the body, link budget analysis, impedance matching and capsule miniaturization. To improve the image quality, transmission efficiency of the antenna has to be improved. This has led to the development of many antenna structures in an ingestible capsule system. Literatures have identified Med Radio and ISM (Industrial, Scientific and Medical) band as operation bands for the WCE systems. This review aims to highlight: (1) design considerations for various antenna types, (2) miniaturization techniques, (3) operating bands, specifications and various design challenges and (4) research gap, advanced design technologies and targets of ingestible antenna system. The main aim of this paper is to tutorial the up-to-date information on the recent antenna designing techniques and challenges for ingestible system....
CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]
CONCLUSION: PEG-J placement and replacement are safe procedures. Although PEG-J durability is variable an elective procedure might be indicated to reduce urgent replacements. PMID: 33021876 [PubMed - as supplied by publisher]
CONCLUSIONS: ESD seems to be safe and effective in the treatment of colorectal neoplasia involving the dentate line and can be considered the best therapeutic strategy. PMID: 33016792 [PubMed - as supplied by publisher]
Conclusions EUS-HTP induces a significant 1-month VTVRR. This effect is assessed accurately by evaluation of necrosis and tumor volumes. Use of VTVRR and Choi criteria, but not RECIST 1.1 criteria, might identify patients who could benefit clinically from EUS-HTP.

CONCLUSION: Esophageal MGCT requires a detailed presentation including long-term survival. Early surgical removal of intramural esophageal neoplasms with potentially malignant features is highly recommended. Radical and/or repeated esophageal resections are the only known therapies with curative potential. PMID: 33012751 [PubMed - as supplied by publisher]
In the newsFirst in this fortnightly update, some news stories. An article in the Guardian by Zoe Williams, Bilge, booze and misogyny: why I'm outraged by a new idea to police pregnant women, about NICE proposals in their draft guidelines on fetal alcohol syndrome, to record a mother's alcohol intake on the child's health record. See the previous What's new post for more.This,about an the first prosecution of an NHS trust for lack of candour, the case involved the death of a patient from a perforated endoscopy, but the duty of candour regulations apply across health care. The CQC brought th...
ConclusionsDC-CO2 insufflation induces substantive cellular damage and hypoxia responses within the first hour of application. The use of HW-CO2 insufflation ameliorates these processes for the first one to one and half hours in a large mammal used to replicate surgery in humans.
CONCLUSIONS: We implemented this simple method in order to secure the devastated airway, sparing the need for a demanding rigid bronchoscopy, or use of a costly ECMO expedient. PMID: 32988709 [PubMed - as supplied by publisher]
We report the case of a patient with a Dieulafoy lesion within a duodenal diverticulum, showing the radiographic images. In this case the use of radiological techniques was of great help for diagnosis, bearing in mind that bleeding from this lesion may be intermittent and had not been revealed by the first endoscopic procedure. Since strong clinical suspicion persisted of active upper GI bleeding an angio-CT scan was performed, which allowed to orient diagnosis and rule out other causes of bleeding inaccessible to endoscopy.

We present three cases of colonic ischemia that can be attributed to the hypercoagulable state related with SARS-CoV2 and disseminated intravascular coagulation. Three males aged 76, 68 and 56 with respiratory distress presented episodes of rectal bleeding, abdominal distension and signs of peritoneal irritation. Endoscopy (case 1) and computed tomography angiography revealed colonic ischemia. One patient (case 2) in which a computed tomography (CT) scan showed perforation of the gangrenous cecum underwent surgery. D-dimer levels were markedly increased (2,170, 2,100 and 7,360 ng/ml) in all three patients. All three patien...
