Vocal and tongue exercise in early to mid-stage Parkinson disease using the Pink1-/- rat. Brain Res 2024; 1837:148958.

Abstract
Vocal and swallowing deficits are common in Parkinson disease (PD). Because these impairments are resistant to dopamine replacement therapies, vocal and lingual exercise are the primary treatment, but not all individuals respond to exercise and neural mechanisms of treatment response are unclear. To explore putative mechanisms, we used the progressive Pink1-/- rat model of early to mid-stage PD and employed vocal and lingual exercises at 6- and 10-months of age in male Pink1-/- and wild type (WT) rats. We hypothesized that vocal and lingual exercise would improve vocal and tongue use dynamics and increase serotonin (5HT) immunoreactivity in related brainstem nuclei. Rats were tested at baseline and after 8 weeks of exercise or sham exercise. At early-stage PD (6 months), vocal exercise resulted in increased call complexity, but did not change intensity, while at mid-stage (10 months), vocal exercise no longer influenced vocalization complexity. Lingual exercise increased tongue force generation and reduced relative optical density of 5HT in the hypoglossal nucleus at both time points. The effects of vocal and lingual exercise at these time points are less robust than in prodromal stages observed in previous work, suggesting that early exercise interventions may yield greater benefit. Future work targeting optimization of exercise at later time points may facilitate clinical translation.

Implications of the composite free flap harvest site on quality of life after head and neck surgery: a prospective series. Int J Oral Maxillofac Surg 2024; 53:275-281. [PMID: 37858382 DOI: 10.1016/j.ijom.2023.09.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 09/09/2023] [Accepted: 09/15/2023] [Indexed: 10/21/2023]
Abstract
Quality of life (QOL) has become a primary determinant of the treatment outcome. There is a poor evidence base regarding the QOL implications of free flap harvest from the various different osseous composite donor sites. This prospective study assessed the impact of free flap harvest on QOL and compared QOL morbidity between fibula, scapula, and iliac crest (deep circumflex iliac artery; DCIA) donor sites in head and neck reconstructive surgery. This was a single-site prospective cohort clinical research study. Fifty-nine patients were recruited between 2017 and 2021; 30 underwent fibula flap reconstructive surgery, 17 scapula flap, and 12 DCIA flap. The patients were assessed using the University of Washington Quality of Life Questionnaire version 4 (UW-QOL v4) preoperatively and again at >12 months postoperatively. The results showed no significant change in the mean global QOL score postoperatively when compared to the preoperative baseline in any of the donor site groups. However, the mean postoperative scores for the appearance domain were significantly lower than the preoperative scores in all of the donor site groups. In addition, fibula flap patients had significantly reduced physical activity and recreation QOL domain scores postoperatively when compared to the preoperative scores.

The utility of parathyroid autofluorescence as an adjunct in thyroid and parathyroid surgery 2023. Head Neck 2023; 45:3157-3167. [PMID: 37807364 DOI: 10.1002/hed.27538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 08/27/2023] [Accepted: 09/24/2023] [Indexed: 10/10/2023] Open
Abstract
Thyroid and parathyroid surgery requires careful dissection around the vascular pedicle of the parathyroid glands to avoid excessive manipulation of the tissues. If the blood supply to the parathyroid glands is disrupted, or the glands are inadvertently removed, temporary and/or permanent hypocalcemia can occur, requiring post-operative exogenous calcium and vitamin D analogues to maintain stable levels. This can have a significant impact on the quality of life of patients, particularly if it results in permanent hypocalcemia. For over a decade, parathyroid tissue has been noted to have unique intrinsic properties known as "fluorophores," which fluoresce when excited by an external light source. As a result, parathyroid autofluorescence has emerged as an intra-operative technique to help with identification of parathyroid glands and to supplement direct visualization during thyroidectomy and parathyroidectomy. Due to the growing body of literature surrounding Near Infrared Autofluorescence (NIRAF), we sought to review the value of using autofluorescence technology for parathyroid detection during thyroid and parathyroid surgery. A literature review of parathyroid autofluorescence was performed using PubMED. Based on the reviewed literature and expert surgeons' opinions who have used this technology, recommendations were made. We discuss the current available technologies (image vs. probe approach) as well as their limitations. We also capture the opinions and recommendations of international high-volume endocrine surgeons and whether this technology is of value as an intraoperative adjunct. The utility and value of this technology seems promising and needs to be further defined in different scenarios involving surgeon experience and different patient populations and conditions.

Universal DNA methylation age across mammalian tissues. NATURE AGING 2023; 3:1144-1166. [PMID: 37563227 PMCID: PMC10501909 DOI: 10.1038/s43587-023-00462-6] [Citation(s) in RCA: 38] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 06/21/2023] [Indexed: 08/12/2023]
Abstract
Aging, often considered a result of random cellular damage, can be accurately estimated using DNA methylation profiles, the foundation of pan-tissue epigenetic clocks. Here, we demonstrate the development of universal pan-mammalian clocks, using 11,754 methylation arrays from our Mammalian Methylation Consortium, which encompass 59 tissue types across 185 mammalian species. These predictive models estimate mammalian tissue age with high accuracy (r > 0.96). Age deviations correlate with human mortality risk, mouse somatotropic axis mutations and caloric restriction. We identified specific cytosines with methylation levels that change with age across numerous species. These sites, highly enriched in polycomb repressive complex 2-binding locations, are near genes implicated in mammalian development, cancer, obesity and longevity. Our findings offer new evidence suggesting that aging is evolutionarily conserved and intertwined with developmental processes across all mammals.

Methods to expose subsurface objects of interest identified from 3D imaging: The intermediate sample preparation stage in the correlative microscopy workflow. J Microsc 2023; 289:107-127. [PMID: 36399637 DOI: 10.1111/jmi.13159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 09/13/2022] [Accepted: 11/08/2022] [Indexed: 11/19/2022]
Abstract
The correlative imaging workflow is a method of combining information and data across modes (e.g. SEM, X-ray CT, FIB-SEM), scales (cm to nm) and dimensions (2D-3D-4D), providing a more holistic interpretation of the research question. Often, subsurface objects of interest (e.g. inclusions, pores, cracks, defects in multilayered samples) are identified from initial exploratory nondestructive 3D tomographic imaging (e.g. X-ray CT, XRM), and those objects need to be studied using additional techniques to obtain, for example, 2D chemical or crystallographic data. Consequently, an intermediate sample preparation step needs to be completed, where a targeted amount of sample surface material is removed, exposing and revealing the object of interest. At present, there is not one singular technique for removing varied thicknesses at high resolution and on a range of scales from cm to nm. Here, we review the manual and automated options currently available for targeted sample material removal, with a focus on those methods which are readily accessible in most laboratories. We summarise the approaches for manual grinding and polishing, automated grinding and polishing, microtome/ultramicrotome, and broad-beam ion milling (BBIM), with further review of other more specialist techniques including serial block face electron microscopy (SBF-SEM), and ion milling and laser approaches such as FIB-SEM, Xe plasma FIB-SEM, and femtosecond laser/LaserFIB. We also address factors which may influence the decision on a particular technique, including the composition, shape and size of the samples, sample mounting limitations, the amount of surface material to be removed, the accuracy and/or resolution of peripheral parts, the accuracy and/or resolution of the technique/instrumentation, and other more general factors such as accessibility to instrumentation, costs, and the time taken for experimentation. It is hoped that this study will provide researchers with a range of options for removal of specific amounts of sample surface material to reach subsurface objects of interest in both correlative and non-correlative workflows.

Food Insecurity and Hearing Loss Are Interrelated: A Cross-Sectional Population-Based Study. J Nutr Health Aging 2023; 27:251-256. [PMID: 37170431 PMCID: PMC10018724 DOI: 10.1007/s12603-023-1900-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 02/15/2023] [Indexed: 03/28/2023]
Abstract
OBJECTIVES We aimed to assess whether objectively measured hearing loss and self-perceived hearing handicap in adults are independently associated with food insecurity, and vice versa. DESIGN Cross-sectional population-based study. POPULATION 2,500 participants aged 50+ years from the Blue Mountains Hearing Study, with both complete pure-tone audiometry data and information on food security status. MEASUREMENTS The pure-tone average of frequencies 0.5, 1.0, 2.0 and 4.0 kHz (PTA0.5-4KHz) >25 dB HL in the better ear, established the presence of hearing loss. Self-perceived hearing handicap was assessed by administering the Hearing Handicap Inventory for Elderly Screening (HHIE-S total scores of ≥8 indicates hearing handicap). A 12-item food security survey was administered, comprising statements related to individual and household food situations. RESULTS Food insecurity was reported by 12.8% of study participants. After adjusting for all potential confounders, any self-perceived hearing handicap significantly increased the likelihood of participants reporting food insecurity by 94% (p<0.0001). Participants reporting any, mild or severe self-perceived hearing handicap had around 2-fold greater odds of experiencing food insecurity. Objectively measured hearing loss did not significantly influence the food security status of study participants. Conversely, food insecurity was significantly associated with both objectively measured hearing loss and self-perceived hearing handicap: multivariate-adjusted OR 1.37 (95% CI 1.01-1.88) and OR 1.83 (95% CI 1.40-2.39), respectively. CONCLUSIONS Food insecurity was an important social determinant of hearing health among community-dwelling adults. Conversely, participants with a significant self-perceived hearing handicap were more likely to experience food insecurity. These findings add to our understanding of the substantial public health impact of both food insecurity and hearing loss and may highlight areas for future intervention.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Suture lateralization in congenital bilateral vocal cord immobility in neonates and infants: A hybrid approach. Int J Pediatr Otorhinolaryngol 2022; 158:111159. [PMID: 35490608 DOI: 10.1016/j.ijporl.2022.111159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 04/15/2022] [Accepted: 04/23/2022] [Indexed: 10/18/2022]
Abstract
INTRODUCTION Bilateral vocal cord immobility (BVCI) is a leading cause of stridor and airway obstruction in neonates which may arise idiopathically, as a result of birth trauma, or in the setting of Central nervous system lesions such as Arnold-Chiari malformation. Although many children with BVCI may be managed conservatively, surgical intervention may be necessary in those patients with ongoing upper airway obstruction. Many interventions have been described including, tracheostomy, cordotomy, cricoid splitting procedures, and arytenoidectomy. Vocal cord suture lateralization has the advantage of being both reversible and less morbid than other surgical interventions for BVCI. This study describes a novel variation of the suture lateralization procedure which aids in correct placement of the suture thus minimizing multiple needle passes and associated laryngeal edema. METHODS A retrospective chart review was undertaken of five patients undergoing suture lateralization of the vocal cord for BVCI at a single institution over a 10 year period. Post-operative voice and swallow outcomes were recorded. RESULTS Of five patients undergoing this procedure four returned to normal diet. One was diagnosed with a progressive neurological disorder and was persistently fed via gastrostomy tube. Three of the five patients spontaneously recovered vocal cord function and went on to have normal voice after suture removal. CONCLUSION Suture lateralization is a safe and effective means of alleviating upper airway obstruction in BVCI. It has the advantages of being reversable and minimally invasive; however, optimal suture placement is both vital and challenging. The novel technique described in this study allows identification of landmarks as and aid to suture placement thus reducing the need for multiple needle passes into the lumen of the larynx.

Abstract
INTRODUCTION Corona-virus Disease 2019 (COVID-19) has had a huge impact on the delivery of healthcare worldwide, particularly elective surgery. There is a lack of data regarding risk of postoperative COVID-19 infection in children undergoing elective surgery, and regarding the utility of pre-operative COVID-19 testing, and preoperative "cocooning" or restriction of movements. The purpose of this present study was to examine the safety of elective paediatric Otolaryngology surgery during the COVID-19 pandemic with respect to incidence of postoperative symptomatic COVID-19 infection or major respiratory complications. MATERIALS AND METHODS Prospective cohort study of paediatric patients undergoing elective Otolaryngology surgery between September and December 2020. Primary outcome measure was incidence of symptomatic COVID-19 or major respiratory complications within the 14 days after surgery. Parents of prospectively enrolled patients were contacted 14 days after surgery and enquiry made regarding development of postoperative symptoms, COVID-19 testing, or diagnosis of COVID-19. RESULTS 302 patients were recruited. 125 (41.4%) underwent preoperative COVID-19 RT-PCR testing. 66 (21.8%) restricted movements prior to surgery. The peak 14-day COVID-19 incidence during the study was 302.9 cases per 100,000 population. No COVID-19 infections or major respiratory complications were reported in the 14 day follow-up period. CONCLUSION The results of our study support the safety of elective paediatric Otolaryngology surgery during the pandemic, in the setting of community incidence not exceeding that observed during the study period.

Abstract
Real-time polymerase chain reaction (RT-PCR) is used to rule out SARS-CoV-2 prior to surgery, however few studies have evaluated patients with negative testing after surgery. Some 499 patients with negative tests were followed for 14 days after surgery, 39 were retested but none developed positive RT-PCR after operation. The risk of developing a positive RT-PCR after surgery was 0.74 per cent.

Comparing the medical coverage provided by four contemporary military combat helmets against penetrating traumatic brain injury. BMJ Mil Health 2021; 168:395-398.

Abstract
INTRODUCTION Modern military combat helmets vary in their shapes and features, but all are designed to protect the head from traumatic brain injury. Recent recommendations for protection against energised projectiles that are characteristic of secondary blast injury is to ensure coverage of both the brain and brainstem. METHOD Graphical representations of essential coverage of the head (cerebral hemispheres, cerebellum and brainstem) within an anthropometrically sized model were superimposed over two standard coverage helmets (VIRTUS helmet, Advanced Combat Helmet (ACH)) and two 'high-cut' helmets (a Dismounted Combat Helmet (DCH)) and Combat Vehicle Crewman (CVC) helmet), both of which are designed to be worn with communications devices. Objective shotline coverage from representative directions of projectile travel (-30 to +30 degrees) was determined using the Coverage of Armour Tool (COAT). RESULTS VIRTUS and ACH demonstrated similar overall coverage (68.7% and 69.5%, respectively), reflecting their similar shell shapes. ACH has improved coverage from below compared with VIRTUS (23.3% vs 21.7%) due to its decreased standoff from the scalp. The 'high-cut' helmets (DCH and CVC) had reduced overall coverage (57.9% and 52.1%), which was most pronounced from the side. CONCLUSIONS Both the VIRTUS and ACH helmets provide excellent overall coverage of the brain and brainstem against ballistic threats. Coverage of both would be improved at the rear by using a nape protector and the front using a visor. This is demonstrated with the analysis of the addition of the nape protector in the VIRTUS system. High-cut helmets provide significantly reduced coverage from the side of the head, as the communication devices they are worn with are not designed to provide protection from ballistic threats. Unless absolutely necessary, it is therefore recommended that high-cut helmets be worn only by those users with defined specific requirements, or where the risk of injury from secondary blast is low.

Abstract
BACKGROUND Despite recommendations that pre-school children use toothpaste containing 500-550 ppm of fluoride, there has been an increase in non-fluoridated toothpastes marketed for children. This study investigated children's toothpaste in Australia. METHODS A comprehensive audit of all toothpastes marketed for pre-school children and available in store in the Macarthur region of NSW, Australia, was carried out. All toothpastes available for purchase were obtained and examined; size and price were catalogued, along with ingredient lists and fluoride levels. RESULTS One hundred and seven individual toothpastes were identified in the audit, with 67 (62.6%) containing no fluoride. Of the 40 fluoridated toothpastes, only 11 (10.3%) contained the recommended level of fluoride of 500-550 ppm. Twenty-two (20.6%) of all toothpastes were made in Australia, all of which were non-fluoridated. Six (5.6%) of the toothpastes studied contained excessive levels of fluoride (1350-1500 ppm). Seventeen of the 20 least expensive toothpastes contained fluoride, while 18 of the 20 most expensive toothpastes were non-fluoridated. CONCLUSIONS Despite expert recommendations, the majority of children's toothpaste available in Australia contains either no fluoride or the wrong levels of fluoride. Further study is needed to determine why this change is occurring and what is influencing the increase in non-fluoride toothpastes on the market.

Abstract
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

Donor site morbidity of composite free flaps in head and neck surgery: a systematic review of the prospective literature. Int J Oral Maxillofac Surg 2021; 50:1147-1155. [PMID: 33531270 DOI: 10.1016/j.ijom.2020.12.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 12/14/2020] [Accepted: 12/17/2020] [Indexed: 11/27/2022]
Abstract
Composite free flaps represent the cornerstone for the repair of osseous defects in the head and neck. For many patients, there are often multiple defect-suitable donor sites that may be utilised as part of the reconstructive process. Therefore, to optimise patient outcomes, an evidence-based approach to donor site selection is required to maximise quality of life and long-term functionality. A systematic review of the literature was conducted in accordance with PRISMA guidelines to evaluate the evidence for donor site selection based on minimising the associated donor site morbidity and optimising patient functionality postoperative. The fibula is associated with the greatest potential risk for wound healing complications. Fibula and scapula harvest has the potential to have a significant impact on physical performance. The iliac crest is most favourable in terms of aesthetic scar healing outcomes. Overall, however, the quality and quantity of evidence for all donor sites is limited. Each site is associated with specific complications and morbidity, of which the surgeon and patient must both be aware. Whilst a cross-sectional informed opinion of the likely advantages/disadvantages of one donor site over another can thus be made, there are few head-to-head studies available that directly compare donor sites.

Abstract
The Society for Acute Medicine launched their ultrasound accreditation in September 2016, involving a practical course alongside completion of scanning competencies. Candidates require a registered supervisor to oversee their training. We present here the results of a survey of attendees of practical courses approximately 2 years after launch. The majority of respondents were Consultants or trainees within AIM. Fourteen of 76 (18.4%) respondents had completed the whole accreditation process, whilst 51 (67.1%) had not completed any of the three individual modules. The biggest barriers to accreditation were seen to be lack of supervisors, and lack of dedicated training time. There was good uptake of available online learning resources with good feedback. These results will be used to help develop the training pathway further and widen access to ultrasound training within the specialty and beyond.

First marine litter survey on beaches in Solomon Islands and Vanuatu, South Pacific: Using OSPAR protocol to inform the development of national action plans to tackle land-based solid waste pollution. MARINE POLLUTION BULLETIN 2020; 161:111827. [PMID: 33213857 DOI: 10.1016/j.marpolbul.2020.111827] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 10/22/2020] [Accepted: 11/02/2020] [Indexed: 06/11/2023]
Abstract
The increasing abundance of marine litter is impacting the environment, human health and economies in the South Pacific. Small Islands Developing States are particularly affected by marine litter, primarily due to insufficient waste management systems. For the first time, marine litter was quantified and characterised on 13 beaches in Solomon Islands and Vanuatu in the South Pacific region using the OSPAR beach litter monitoring guidelines. A total of 1053 (±1017) and 974 (±745) items of litter per 100 m beach were recorded in Solomon Islands and Vanuatu respectively. Litter composition and distribution show that the majority of the litter comes from local land-based sources and large quantities of fragments and single use plastics were found by cities and river mouths. Actions to reduce single use plastic, improve collection, reuse and recycling, together with outreach campaigns would reduce marine litter significantly in these countries. Furthermore, there is great potential to develop a more circular economy to manage the substantial quantities of recyclable items that were found stranded on the beaches.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study. Br J Surg 2020; 107:1023-1032. [PMID: 32026470 DOI: 10.1002/bjs.11453] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 09/21/2019] [Accepted: 11/08/2019] [Indexed: 01/14/2023]
Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
The ProtoDUNE-SP is a single-phase liquid argon time projection chamber (LArTPC) prototype for the Deep Underground Neutrino Experiment (DUNE). Signals from 15,360 electronic channels are received by 60 Reconfigurable Cluster Elements (RCEs), which are processing elements designed at SLAC for a wide range of applications and are based upon the “system-onchip” Xilinx Zynq family of FPGAs. The RCEs are housed in industry-standard ATCA shelves on a custom blade, called the Cluster on Board (COB). The RCE platform and its processing functions for the ProtoDUNE-SP will be presented.

Abstract
OBJECTIVES The first tracheostomy tube change is typically performed on days 5-7 post-operatively, however recent international consensus guidelines suggested that, with maturation sutures, days 3-5 is appropriate. We evaluate whether a first tube change on day 2 post-operatively is safe and effective. METHODS We carried out a retrospective review of all patients undergoing tracheostomy between 2009 and 2018. Exclusion criteria were patients on whom the senior authors did not operate, operations done elsewhere, cases where maturation sutures were not used or a patient died prior to first tube change. We noted patient details, indication for tracheostomy, the need for long-term ventilation, timing of the first tube change, decannulation and need for surgical closure of persistent tracheocutaneous fistula. RESULTS 93 patients were identified, of which 83 were included. The age range was 0-16 years, with the youngest day one of life and an overall mean age of 1.91 years. 59% of patients required long-term ventilation due to various co-morbidities. 26 patients (31%) underwent a first tube change on day 2 post-operatively. All these were uneventful and were irrespective of the patient's need for ventilation. Of the 42 patients who have subsequently been decannulated, 33 (79%) were noted to have a persistent tracheocutaneous fistula requiring surgical closure, four of whom needed revision closure. CONCLUSIONS This study shows that a first tube change on day 2 post-operatively is safe, facilitating earlier discharge from intensive care, allowing shorter length of sedation, earlier start to parent/carer training and wound assessment.

Abstract
ObjectivesTo describe our technique of using reverse frontal bone graft for FOAR for patients with metopic or coronal synostosis.DesignRetrospective analysis of digital records for operation notes and radiological images.SubjectsSince April 2014, 16 patients underwent FOAR without using orbital bar.MethodsWe plan a frontal bone graft using Marchac template and increase the angles on side by 1 cm. This graft is then reversed and supra orbital margins are drilled out. The orbital bar is then removed and drilled down to make bone dust which is then used to fill gaps on exposed dura. The reversed frontal graft is then placed in front and secured via absorbable sutures, plate and screws.ResultsAll 16 patients who underwent this technique have shown excellent cosmetic results with no complications or non healing. Removing orbital bar does not cause any cosmetic defect since orbital rims are drilled out in reverse frontal bone graft. The removed orbital bar provides an excellent source of bone dust to cover gaps on exposed dura.ConclusionsWe present our technique of FOAR without using orbital bar, which is drilled down to bone dust to fill gaps. This has shown excellent cosmetic results so far with no complications. This addresses the issue of temporal thinning.

Abstract
Temporary and permanent tracheostomies are required in children to manage actual or anticipated long-term ventilatory support, to aid secretion management or to manage fixed upper airway obstruction. Tracheostomies may be required from the first few moments of life, with the majority performed in children < 4 years of age. Although similarities with adult tracheostomies are apparent, there are key differences when managing the routine and emergency care of children with tracheostomies. The National Tracheostomy Safety Project identified the need for structured guidelines to aid multidisciplinary clinical decision making during paediatric tracheostomy emergencies. These guidelines describe the development of a bespoke emergency management algorithm and supporting resources. Our aim is to reduce the frequency, nature and severity of paediatric tracheostomy emergencies through preparation and education of staff, parents, carers and patients.

Abstract
Background Relapsed/metastatic salivary gland carcinomas (SGCs) have a wide diversity of histologic subtypes associated with variable clinical aggressiveness and response to local and systemic therapies. We queried whether comprehensive genomic profiling could define the tumor subtypes and uncover clinically relevant genomic alterations, revealing new routes to targeted therapies for patients with relapsed and metastatic disease. Patients and methods From a series of 85 686 clinical cases, DNA was extracted from 40 µm of formalin-fixed paraffin embedded (FFPE) sections for 623 consecutive SGC. CGP was carried out on hybridization-captured, adaptor ligation-based libraries (mean coverage depth, >500×) for up to 315 cancer-related genes. Tumor mutational burden was determined on 1.1 Mb of sequenced DNA. All classes of alterations, base substitutions, short insertions/deletions, copy number changes, and rearrangements/fusions were determined simultaneously. Results The clinically more indolent SGC including adenoid cystic carcinoma, acinic cell carcinoma, polymorphous low-grade adenocarcinoma, mammary analog secretory carcinoma, and epithelial-myoepithelial carcinomas have significantly fewer genomic alterations, TP53 mutations, and lower tumor mutational burden than the typically more aggressive SGCs including mucoepidermoid carcinoma, salivary duct carcinoma, adenocarcinoma, not otherwise specified, carcinoma NOS, and carcinoma ex pleomorphic adenoma. The more aggressive SGCs are commonly driven by ERBB2 PI3K pathway genomic alterations. Additional targetable GAs are frequently seen. Conclusions Genomic profiling of SGCs demonstrates important differences between traditionally indolent and aggressive cancers. These differences may provide therapeutic options in the future.

Abstract
OBJECTIVE To evaluate the proportion of blood samples diagnosed with reticulocytosis without anaemia in cats and dogs and report the aetiology and mortality rate of affected animals. MATERIALS AND METHODS Retrospective multicentre study including haematological examination of 3956 cats and 11,087 dogs admitted to seven German veterinary clinics (2012 to 2014). The proportion of blood samples with reticulocytosis without anaemia was calculated, and after exclusion of multiple measurements of the same animal, clinical data were evaluated. Animals with reticulocytosis without anaemia were classified as healthy or diseased, and diseased patients were assigned to 12 disease groups. Pretreatment (i.e. non-steroidal anti-inflammatory drugs, glucocorticoids, dipyrone) was recorded. RESULTS The proportion of blood samples with reticulocytosis without anaemia was 3·1% (124/3956) in cats and 4·4% (492/11,087) in dogs. Overall, 1·8% (2/111) of cats and 1·5% (7/458) of dogs with reticulocytosis without anaemia were healthy. Blood loss/anaemia, cardiac/respiratory disorders, gastrointestinal disorders and inflammatory disorders as well as cancer were the most frequent underlying diseases. Pretreatment was noted in 39·5% (43/111) of cats and 42·4% (194/458) of dogs. The mortality rate was 37·8% (42/111) in cats and 29·7% (136/458) in dogs with reticulocytosis without anaemia; the median survival time in non-survivors was 1 day (range: 0 to 376 days in cats, 0 to 444 days in dogs). CLINICAL SIGNIFICANCE In both species, reticulocytosis without anaemia was observed in a low proportion of blood samples (dogs>cat). Though a bias towards sick animals is possible in our sample, reticulocytosis without anaemia was mainly seen in diseased animals and associated with a mortality rate of approximately one-third of patients.

Abstract
Discoveries on the genetics of resource acquisition efficiency are limited by the ability to measure plant roots in sufficient number and with adequate genotypic variability. This paper presents a root phenotyping study that explores ways to combine live imaging and computer algorithms for model-based extraction of root growth parameters. The study is based on a subset of barley Recombinant Chromosome Substitution Lines (RCSLs) and a combinatorial approach was designed for fast identification of the regions of the genome that contribute the most to variations in root system architecture (RSA). Results showed there was a strong genotypic variation in root growth parameters within the set of genotypes studied. The chromosomal regions associated with primary root growth differed from the regions of the genome associated with changes in lateral root growth. The concepts presented here are discussed in the context of identifying root QTL and its potential to assist breeding for novel crops with improved root systems.

Abstract
African American men (AA) carry unequal burdens of several conditions including cancer, diabetes, hypertension, and HIV. Engagement of diverse populations including AA men in research and health promotion practice is vital to examining the health disparities that continue to plague many racially and ethnically diverse communities. To date, there is little research on best practices that indicate locations, community areas and settings to engage AA men in research and health promotion. Traditionally, the AA church has been a key area to engage AA men and women. However, changing tides in attendance of AA parishioners require additional information to identify areas where AAs, particularly, AA men congregate. The AA barbershop has been identified as a place of social cohesion, cultural immersion and solidarity for AA men but specific sub-populations of AA men may be underrepresented. To further investigate additional locales where AA men congregate, this study engaged AA barbers and clients in several urban community barbershops in Chicago, Illinois. 127 AA men over age 18y/o receiving grooming services in 25 Chicago area barbershops across 14 predominantly AA communities were consented and recruited for a quantitative survey study. The self-administered surveys were completed in ~15 min and $10 compensation was provided to men. Descriptive statistics were reported for demographic variables and for frequency of responses for locations to find AA men of specific age ranges for health promotion and screening activities. Outside of the traditionally used churches or barbershops, the top recommended recruitment sites by age were: 18-29y/o- city park or a recreational center; 30-39y/o- gym, bars or the street; 40-49y/o- various stores, especially home improvement stores, and the mall; and 50y/o+- fast food restaurants in the mornings, such as McDonalds, and individual's homes. The study participants also reported that locations where AA men congregate vary by age. Findings from this study illustrate that AA barbers and barbershops remain a key stakeholder in health promotion among AA men. The findings also demonstrate the need for additional research to examine best practices for identifying locations where diverse groups of AA men that vary by age and sexual orientation may congregate in order to support increased health promotion among AA men.

Abstract
Enhancing feed efficiency (FE) in cattle continues to be an important goal in the beef industry. Previous research suggests improving FE may alter calpain system activity, potentially having negative effects on meat tenderness. The objective of this study was to assess the potential influence of beef cattle FE on postmortem meat tenderness. During the growing phase, 181 crossbred steers were fed for 76 d at the University of Missouri on a whole shell corn-based diet (MU-Corn; = 90) or a roughage-based diet (MU-Rough; = 91). Within diet, steers were classified for FE based on residual feed intake (RFI) calculations. Within each growing phase diet, the 12 most feed efficient (HFE; average RFI -3.33 ± 0.77) and 12 least feed efficient (LFE; average RFI 2.90 ± 0.94) steers (48 steers total) were selected and shipped to Iowa State University for the finishing phase. Steers were fed in pens with GrowSafe bunks and equally assigned to a cracked corn-based finishing diet (ISU-Corn) or a byproduct-based finishing diet (ISU-Byp) for the 87-d finishing phase. After a 24-h chill, rib sections were collected from all carcasses and aged for 2 or 14 d prior to analysis of calpastatin activity and calpain 1 autolysis (d 2), troponin-T degradation (d 2 and 14), proximate composition (d 2), and Warner-Bratzler shear force (WBSF; d 14). Data were analyzed as a 2 × 2 × 2 factorial, with steer or steak as the experimental unit ( = 6 per treatment combination). There were no 3- or 2-way interactions ( ≥ 0.12) noted for any data, with the exception of steak lipid content, which tended ( = 0.08) to be affected by FE × Iowa State University diet. Steaks from LFE steers had greater lipid content compared with steaks from HFE steers within ISU-Byp, with no differences due to FE within ISU-Corn. Growing diet did not affect calpastatin activity, calpain 1 autolysis, or troponin T degradation ( ≥ 0.12); however, MU-Rough had greater WBSF than MU-Corn ( = 0.05). Day-2 calpastatin activity tended ( = 0.10) to be greater in steaks from HFE vs. LFE steers, although no differences due to FE classification were observed for calpain 1 protein, troponin-T degradation, or WBSF ( ≥ 0.13). Finishing diet did not affect calpastatin activity, calpain 1 autolysis, d-2 troponin-T degradation, or WBSF ( ≥ 0.24); however, d-14 troponin-T degradation was greater in ISU-Corn than in ISU-Byp ( = 0.005). In this study, using phenotypic extremes for FE revealed a tendency for greater calpastatin activity only in highly feed-efficient steers; however, these data indicate that high-fiber diets may negatively impact meat tenderness, and further work is needed to clarify the influence of diet type on parameters of meat tenderness.

Abstract
In this opinion paper of the Journal of Endocrinological Investigation, leading experts in the field report on their current clinical experience with a novel approach for thyroid gland surgery, namely, "transoral thyroidectomy" (TOT). This feasible and novel surgical procedure does not require visible incisions and is, therefore, a truly scarless surgery. Patients meeting the following criteria can be considered as candidates for TOT: (a) an ultrasonographically (US) estimated thyroid diameter ≤10 cm; (b) US-estimated gland volume ≤45 mL; (c) nodule size ≤50 mm; (d) presence of a benign tumor such as a thyroid cyst or a single- or multi-nodular goiter; (e) Bethesda 3 and/or 4 category and (f) papillary microcarcinoma without the evidence of metastasis. The procedure is conducted via a three-port technique at the oral vestibule using a 10-mm port for the 30° endoscope and two additional 5-mm ports for the dissecting and coagulating instruments. TOT is performed using conventional endoscopic instruments and is probably the best scarless approach to the thyroid because of the short distance between the thyroid and the incisions placed intra-orally that do not result in any cutaneous scar and upon following the surgical planes. Experts in TOT organized a working group of general, endocrine, head and neck ENT surgeons and endocrinologist to develop the standards for practicing this emerging technique.
