Frontal Balloon Sinuplasty in Complicated Acute Pediatric Rhinosinusitis (ARS).

Case Rep Otolaryngol 2022 14;2022:7232588. Epub 2022 May 14.

Department of Otolaryngology - Head and Neck Surgery, Washington University in Saint. Louis, School of Medicine, St Louis, MO 63110, USA.

Utilization of frontal balloon sinuplasty in pediatric complicated acute rhinosinusitis (ARS) is demonstrated to be a safe and expedient alternative to other procedures such as trephination or functional endoscopic sinus surgery (FESS) in this case series. We performed a retrospective review of six pediatric cases of frontal balloon sinuplasty for ARS with intracranial complications at a tertiary academic center. Patients underwent unilateral ( = 5) or bilateral dilation ( = 1) in addition to functional endoscopic sinus surgery (FESS) including anterior ethmoidectomy ( = 5) and maxillary antrostomy ( = 6).

Restoration for the foregut surgery: bridging gaps between foregut surgery practice and academia.

J Minim Invasive Surg 2021 Dec;24(4):175-179

Division of Foregut Surgery, Department of Surgery, Korea University College of Medicine, Seoul, Korea.

Foregut surgery largely involves benign diseases, and not only malignant diseases. However, for foregut surgeons in Asia, this fact has not been extensively utilized in their clinical practice due to the high burden of gastric cancer surgery. Although the prevalence of gastroesophageal reflux disease (GERD) in Eastern Asia, including Korea, is increasing, antireflux surgery (ARS) is still a fairly rare procedure in Korea. Read More

Evaluation of Companion Diagnostics in Scientific Advice and Drug Marketing Authorization Applications by the European Medicines Agency.

Front Med (Lausanne) 2022 6;9:893028. Epub 2022 May 6.

Dutch Medicines Evaluation Board (CBG-MEB), Utrecht, Netherlands.

With the implementation of the new EU regulation on diagnostics (IVDR) in May 2022, notified bodies will be required to assess Companion Diagnostics (CDx). The EMA and national medicines agencies will be consulted on the performance and safety of CDx. In this paper, we report on our systematic review on how the EMA has dealt with CDx in dossiers for marketing authorization procedures, in 2017-2019, and in scientific advice procedures in 2016-2020, prior to the implementation of the new IVDR.

Anticholinergic Drug Exposure Increases the Risk of Delirium in Older Patients Undergoing Elective Surgery.

Front Med (Lausanne) 2022 6;9:871229. Epub 2022 May 6.

Geriatric Center and Department of Psychiatry and Psychotherapy, Tübingen University Hospital, Tübingen, Germany.

Introduction: Postoperative delirium (POD) is a common and serious adverse event of surgery in older people. Because of its great impact on patients' safety and quality of life, identification of modifiable risk factors could be useful. Although preoperative medication intake is assumed to be an important modifiable risk factor, the impact of anticholinergic drugs on the occurrence of POD seems underestimated in elective surgery.

Effects of habitat and sampling time on bacterial community composition and diversity in the gut of the female house fly, Musca domestica Linnaeus (Diptera: Muscidae).

Med Vet Entomol 2022 May 22. Epub 2022 May 22.

USDA-ARS, Center for Grain and Animal Health Research, Arthropod-Borne Animal Diseases Research Unit, Manhattan, Kansas, USA.

Adult house flies feed and breed in a variety of microbe-rich habitats and serve as vectors for human and animal pathogens. To better understand their role in harbouring and disseminating bacteria, we characterized the composition and diversity of bacterial communities in the gut of female house flies collected from three different habitats in Kansas: agricultural (dairy farm), urban (business area dumpsters) and mixed (business located between residential and animal agriculture areas). Bacterial community composition and diversity were influenced more by the house flies' habitat than by sampling time. Read More

Whole genome sequencing uncovers the structural and transcriptomic landscape of hexaploid wheat/Ambylopyrum muticum introgression lines.

Plant Biotechnol J 2022 May 22. Epub 2022 May 22.

Earlham Institute, Norwich, Norfolk, NR4 7UZ, UK.

Wheat is a globally vital crop, but its limited genetic variation creates a challenge for breeders aiming to maintain or accelerate agricultural improvements over time. Introducing novel genes and alleles from wheat's wild relatives into the wheat breeding pool via introgression lines is an important component of overcoming this low variation but is constrained by poor genomic resolution and limited understanding of the genomic impact of introgression breeding programmes. By sequencing 17 hexaploid wheat/Ambylopyrum muticum introgression lines and the parent lines, we have precisely pinpointed the borders of introgressed segments, most of which occur within genes.

Department of Animal and Range Sciences New Mexico State University, Las Cruces, NM 88003, USA.

Management strategies utilized during pre-breeding development of replacement heifers can impact fertility and the ovarian reserve. Angus-Hereford crossbred heifers (n = 233) were utilized over a three-year period to determine the effects of administration of a growth promoting implant at either branding or weaning on growth, reproduction, and ovarian development. Heifer calves were randomly assigned to one of three treatments: 1) non-implanted controls (CON; n = 79), 2) implanted at approximately 2 mo of age (average calf age = 58 d) with Synovex-C (BIMP, n = 82), or 3) implanted at approximately 7mo of age (average calf age = 210 d) with Synovex-C (WIMP; n = 72).

A Review of Essential Oils as Antimicrobials in Foods with Special Emphasis on Fresh Produce.

J Food Prot 2022 May 19. Epub 2022 May 19.

Residue Chemistry and Predictive Microbiology Research unit, U.S. Department of Agriculture, Agricultural Research Service, Eastern Regional Research Center, 600 East Mermaid Lane, Wyndmoor, PA 19038-8551.

Consumer safety concerns over established fresh produce washing methods, combined with demand for organic and clean label food, has led to the exploration of novel methods of produce sanitization. Essential oils (EOs), extracted from commonly found plants have potential as clean label sanitizers, as they are naturally derived and act as antimicrobials as well as antioxidants. In this review, the antimicrobial abilities of EOs are explored in the following categories: individually and in-combination, as emulsions, combined with existing chemical and physical preservation methods, incorporated into films and coatings, and in vapor phase.
