A chemical analysis revealed 4-acryloylmorpholine (ACMO); isobornyl methacrylate (IBMA), and lauryl acrylate in one glue sample. Seven patients were patch tested with dilutions of the identified substances and six of seven were positive for ACMO 0.5% pet.
An outbreak of occupational ACD, likely from ACMO in a glue is described. Further investigations are needed to corroborate the role played by each compound identified in the chemical analyses.

To compare the spectral performance of three rapid kV switching dual-energy CT (DECT) systems on virtual monoenergetic images (VMIs) at low-energy levels on abdominal imaging.
A multi-energy phantom was scanned on three DECT systems equipped with three different gemstone spectral imaging (GSI) platforms GSI (1st generation, GSI-1st), GSI-Pro (2nd generation, GSI-2nd ), and GSI-Xtream (3rd generation, GSI-3rd). Acquisitions on the phantom were performed with a CTDI
close to 11mGy. For all platforms, raw data were reconstructed using filtered-back projection (FBP) and a hybrid iterative reconstruction algorithm (ASIR-V at 50%; AV50). A deep-learning image reconstruction (DLR) algorithm (TrueFidelity) was used only for the GSI-3rd. Noise power spectrum (NPS) and task-based transfer function (TTF) were evaluated from 40 to 80 keV of VMIs. A detectability index (d') was computed to assess the detection of two contrast-enhanced lesions according to the keV level used.
For all GSI platforms, the noise magnitthm on the GSI-3rd platform reduced noise and improved spatial resolution and detectability without changing the noise texture for VMIs at low keV. The choice of the best energy level in VMIs depends on the platform and the reconstruction algorithm.Impaired nutrition status is recognized as a risk factor for worse clinical outcomes in patients with chronic obstructive pulmonary disease (COPD). The aims of this study were to investigate how undernutrition is diagnosed, its prevalence, and whether there is an association between this condition and clinical outcomes in patients with COPD. The search for this systematic review of observational studies (PROSPERO CRD42020191888) was performed in the PubMed, Embase, and Scopus databases, with no date or language restrictions. The studies had to report data on the diagnosis of undernutrition and its association with mortality, exacerbation, length of hospital stay, or quality of life in adult patients with COPD. A meta-analysis with a random-effects model was performed to combine data. Forty-nine studies were included (20 of them classified as having a low risk of bias), and the most common diagnostic method of undernutrition was body mass index (BMI) (n = 36). The pooled prevalence of undernutrition was equal to 20% (95% CI, 0.15-0.25; I² = 100%), and it was associated with mortality (risk ratio = 1.97; 95% CI, 1.55-2.50; I² = 98%), exacerbation (risk ratio = 1.73; 95% CI, 1.03-2.91; I² = 96%), and poorer quality of life (mean difference = 8.25; 95% CI, 5.40-11.10; I² = 79%). For all outcomes, the certainty of evidence was very low. In conclusion, undernutrition is prevalent and is associated with poorer outcomes in patients with COPD. However, undernutrition is mainly diagnosed by BMI, which underreports its prevalence, and the certainty of the evidence is very low.Individuals with temporal lobe epilepsy (TLE) may have significant language deficits. Language capabilities may further decline following temporal lobe resections. The language network, comprising dispersed gray matter regions interconnected with white matter fibers, may be atypical in individuals with TLE. This review explores the structural changes to the language network and the functional reorganization of language abilities in TLE. We discuss the importance of detailed reporting of patient's characteristics, such as, left- and right-sided focal epilepsies as well as lesional and nonlesional pathological subtypes. These factors can affect the healthy functioning of gray and/or white matter. Dysfunction of white matter and displacement of gray matter function could concurrently impact their ability, in turn, producing an interactive effect on typical language organization and function. Surgical intervention can result in impairment of function if the resection includes parts of this structure-function network that are critical to language. In addition, impairment may occur if language function has been reorganized and is included in a resection. Conversely, resection of an epileptogenic zone may be associated with recovery of cortical function and thus improvement in language function. selleck We explore the abnormality of functional regions in a clinically applicable framework and highlight the differences in the underlying language network. Avoidance of language decline following surgical intervention may depend on tailored resections to avoid critical areas of gray matter and their white matter connections. Further work is required to elucidate the plasticity of the language network in TLE and to identify sub-types of language representation, both of which will be useful in planning surgery to spare language function.Samples of white leg shrimp, Penaeus vannamei, were collected on a monthly basis from freshwater ponds with the salinity of 0 ppt located at Tiruvannamalai and Villupuram districts in Tamil Nadu, India for screening of viral and fungal pathogens. Totally, 130 shrimp samples were collected from 67 freshwater ponds and screened for white spot syndrome virus (WSSV), infectious myonecrosis virus (IMNV), infectious hypodermal and haematopoietic necrosis virus (IHHNV) and Enterocytozoon hepatopenaei (EHP) by PCR and RT-PCR using pathogen-specific primers. Among the samples screened, one sample was found to be positive to WSSV, two samples showed positive to IMNV and two samples positive for EHP. No sample showed positive to IHHNV. The WSSV detected in the sample was found to be a new strain of WSSV and highly virulent. The inoculum prepared from freshwater reared WSSV or IMNV-infected shrimp caused 100% mortality in experimental infection studies. The PCR and RT-PCR results revealed the presence of WSSV and IMNV in different organs of experimentally infected shrimp, respectively. No clinical signs were observed in experimentally EHP-injected shrimp, although the PCR results revealed the presence of EHP in experimentally infected shrimp.Several hundred catfish species (order Siluriformes) belonging to 11 families inhabit Africa, of which at least six families are endemic to the continent. Although four of those families are well-known to belong to the 'Big-Africa clade', no previous study has addressed the phylogenetic placement of the endemic African catfish family Austroglanididae in a comprehensive framework with molecular data. Furthermore, interrelationships within the 'Big-Africa clade', including the most diverse family Mochokidae, remain unclear. This study was therefore designed to help reconstruct inter- and intrarelationships of all currently valid mochokid genera, to infer their position within the 'Big Africa clade' and to establish a first molecular phylogenetic hypothesis of the relationships of the enigmatic Austroglanididae within the Siluriformes. We assembled a comprehensive mitogenomic dataset comprising all protein coding genes and representing almost all recognized catfish families (N = 33 of 39) with carefully selectedenetic relationships of C. macropterus have been controversial in the past, and because we and other researchers assumed that this species would be resolved as sister to most or all other members of Chiloglanis. The apparent paraphyly of Synodontis with respect to Microsynodontis provided an additional surprise, with Synodontis punu turning out to be the sister group of the latter genus.
The World Health Organisation recommends that induction of labour (IOL) be performed only with a clear medical indication. Australian rates of IOL appear to be rising, with more than one-third of women having labour induced. This may reflect changing clinician and consumer perceptions of the benefits and potential harms of term IOL.
To understand recent trends in the rates and indications for IOL.
A retrospective cohort study was undertaken in a Level 6 maternity facility, in metropolitan South-East Queensland, Australia. Routinely collected data were gathered between 2015 and 2020. Exclusion criteria were multiple pregnancies, stillbirth and pre-labour rupture of membranes. Pre-labour rupture of membranes was excluded due to inability to assess if IOL for this indication was a true induction or augmentation of labour. Indications for induction were grouped into maternal, fetal, elective indications, 'post-dates' and decreased fetal movements (DFM). Rates of IOL and frequency of the various indications were compared over time.
About 46530 livebirths occurred during the study period, with labour induced in 31.7%. The proportion of women undergoing IOL increased from 29.8% in 2015 to 33.4% in 2019 (P<0.001). The proportion of inductions for DFM and elective indications increased over time, with a substantial decrease in 'post-dates' IOL.
This large contemporary analysis of IOL trends in Australia has demonstrated rising rates and changing indications for IOL. There remain large knowledge gaps in areas such as care of women with DFM, definitions and management of 'post-term pregnancy', and the economic and service impacts of rising trends in the rate of IOL.

Epidural blood patch is a common effective treatment for postdural puncture headache after accidental dural puncture during labor and may be done in conventional or fluoroscopy-guided methods. The aim of this study was to compare intensity of headache at the time of discharge from the hospital and to compare blood volumes injected in conventional epidural blood patches versus fluoroscopic-guided blood patches and evaluate the side effects of both method of treatment.
Between the years 2010 and 2020, 84 patients who were diagnosed with postdural puncture headache received either a conventional epidural blood patch or a fluoroscopic-guided blood patch. Blood volumes were compared and evaluation of side effects was made based on data collected during and after the procedure.
Eighty-four patients were included in this study. Fifty-two women in the conventional epidural blood patch group and 32 in the fluoroscopic-guided blood patch group. Women in the conventional epidural blood patch group received statistically significantly higher doses of blood than women in the fluoroscopic-guided blood patch group conventional method 29ml IQR [23-36] versus fluoroscopic method 16ml, IQR [12-18], p<.001 with no difference in headache pain intensity at hospital release. There was no difference between groups in hospital length of stay, or persistent PDPH. There was also no difference chronic headache or backache between the two groups.
Women who received fluoroscopic epidural blood patch required a much lower volume of blood injected while there was no difference between groups in headache pain intensity at discharge.
