The study's aim was to identify and validate phenotypes of patients with musculoskeletal (MSK) pain based on eleven common prognostic factors across the biopsychosocial domains. Using a sample of n=435 patients attending physiotherapy in primary care, latent class analysis identified five groups. The five groups mainly differed in terms of severity across the well-established prognostic factors. Outcomes at 3 months reflected baseline scores; those with a more severe profile had worse clinical outcomes. Two of the five groups were separated on differing patterns of mental distress and fear avoidance. This article is protected by copyright.

METHOD A convenience sample of patients with traumatic brain injury, who were non-communicative and using invasive mechanical ventilation. Pain was evaluated by two observers who were blinded from each other. Assessments were performed at baseline via the performance of a painful procedure (aspiration of secretions) and a non-painful procedure (rubbing with a gauze). Assessments were repeated after application of procedures on days one and six of hospitalization in an intensive care unit. Data were collected between January and December 2016. RESULTS 134 patients, were included in the study. Of these, 76.1% were men. The mean age of participants was 45.2 (SD 17.5) years. The pain score significantly increased during the painful procedure when compared with the baseline measure and compared with the non-painful procedure (p less then 0.001). Patients displayed a greater number of pain-indicating behaviors during the painful procedure on day six, compared with day one (p less then 0.05). This finding coincided with a reduced level of sedation and a greater level of consciousness. CONCLUSION The ESCID scale detects pain behaviors and discriminates among the different types of stimulation in patients with brain injury, who are uncommunicative and with mechanical ventilation, with good reliability. The ability for patients with brain injury to express behaviors is limited because of the low level of consciousness and the deep level of sedation. IMPACT This research will have an impact on the practice of pain assessment in patients with brain injury, representing a first step to adapt the content of the ESCID to patients with brain injury.

In barley, there is evidence that changes in gene copy number underlie important agronomic traits. The recently released reference sequence of barley represents a valuable genomic resource for unveiling the incidence of CNVs that affect gene content and identifying sequence features associated with CNV formation. Using exome sequencing and read count data, we detected 16,605 deletions and duplications that affect barley gene content by surveying a diverse panel of 172 cultivars, 171 landraces, 22 wild relatives and other 32 uncategorized domesticated accessions. The quest for segmental duplications (SDs) in the reference sequence revealed many low-copy repeats, most of which overlap predicted coding sequences. Statistical analyses revealed that the incidence of CNVs increases significantly in SD-rich regions, indicating that these sequence elements act as hot spots for the formation of CNVs. This study delivers a comprehensive genome-wide study of CNVs affecting barley gene content and implicates SDs in the molecular mechanisms that lead to the formation of this class of CNVs.

A hexaphenylbenzene precursor was therefore designed, which cannot undergo, due to steric restrictions, a complete planarization reaction. This precursor was transformed under oxidative cyclo-dehydrogenation conditions to a π-extended [5]helicene, which was fully characterized including X-ray diffraction analysis. © 2020 WILEY-VCH Verlag GmbH & Co.

Two new studies in The EMBO Journal by Began et al and Liu et al now link bacterial rhomboid proteases to membrane protein degradation, showing striking similarities to what is known about eukaryotic rhomboid family proteins, thus pointing toward a conserved membrane surveillance mechanism. © 2020 The Authors.Cutaneous vasculitis can be classified into two types based on the affected vessel size small vessel vasculitis predominantly affecting dermal venules, and muscular vessel vasculitis as found in cutaneous arteritis predominantly affecting arteries located at the dermal-subcutaneous junction. We describe two cases with a novel small vessel vasculitis disorder, which exclusively affected arterioles in the mid-dermis, and demonstrate clinical and pathological difference distinct from cutaneous polyarteritis nodosa and cutaneous venulitis. Both patients were male, and presented with painful infiltrative plaques, involving the palms, soles, and thighs without extracutaneous involvement except for fever and arthralgia. Histopathological examination revealed vasculitis in the mid-dermis characterized by a predominant infiltration of neutrophils with vessel wall fibrinoid necrosis and leukocytoclasia identical to the features of leukocytoclastic vasculitis, except that the affected vessels were arterioles rather than venules. Serological examinations showed normal levels of serum complements, immune complexes, and antineutrophil cytoplasmic antibodies, and vasculitis disorders associated with systemic diseases were excluded in both patients. The patients showed a good response to short-term treatment with prednisolone up to 30 mg. This novel cutaneous arteriolitis clinicopathologically different from both cutaneous venulitis and cutaneous arteritis appears to be a skin-limited disorder. This article is protected by copyright.

Fatty acids (FA) are critical for normal brain development, but their transport across the placenta in IUGR pregnancies is poorly understood. This study used a baboon model of IUGR (maternal nutrient restriction, MNR) to investigate placental expression of FA transport and binding proteins, and to determine gestational age-related changes in maternal and fetal plasma FA concentrations. We found MNR to be associated with increased placental expression of FA binding and transport proteins in late gestation, with fetal plasma FA concentrations that were similar to those of control animals. This study is the first to report a profile of fetal and maternal plasma FA concentrations in a baboon model of growth restriction with data that suggest adaptation of placental transport to maintain delivery of critically needed FA. ABSTRACT Intrauterine grow FABP5 expression was increased in MNR compared to control at GD170, as was MVM FATP2 and FATP6 expression at GD140 and FATP2 expression at GD170. BM FATP4 and FATP6 expression was increased in MNR at GD140. Fetal plasma FA concentrations were similar in control and MNR. These data suggest adaptation of placental transport to maintain delivery of critically needed FAs for fetal growth and brain development. This article is protected by copyright. All rights reserved.

The current study extends the application of the Neighborhood Inventory for Environmental Typology (NIfETy) through the development and evaluation of measures of social context for a longer period of observation (3 years) and at a larger area of aggregation (census tract clusters) compared to previous studies using measures at the block-face level from a single observation. Observations from the 172-item inventory were collected from a random sample of block faces (n = 793) in Baltimore City annually over a three-year period. Through a multistep process including replication of previous measures, data reduction, and factor analysis, six unique neighborhood-level indices were generated to describe the environmental context drug and alcohol use, violence, physical disorder, epicenter, youth activity, and improvements. An assessment of measurement consistency and validity provided support for some indices, while others had notable limitations. These indices can assist local policymakers and public health practitioners assessing the needs of individual neighborhoods and evaluating the effectiveness of place-based interventions designed to improve the neighborhood environment and population health outcomes. © 2020 Society for Community Research and Action.OBJECTIVE To assess pharmacokinetics and safety of diazepam nasal spray (NRL-1; VALTOCO®) in pediatric and adult patients with epilepsy in seizure and nonseizure states. METHODS A single dose of diazepam nasal spray (5, 10, 15, or 20 mg based on weight) was administered during each of two conditions (ictal/peri-ictal and interictal condition) to patients 6-65 years old with partial or generalized epilepsy with motor seizures or seizures with clear alteration of awareness; a second dose was permitted if needed for persistent seizures. Dosing could be interictal or ictal/peri-ictal first, with a washout of ≥14 days. MRTX1719 ic50 Blood samples for pharmacokinetic analysis were taken at prespecified time points. Treatment-emergent adverse events (TEAEs), sedation, nasal irritation, nasal mucosal pain, and olfactory changes were assessed. RESULTS Of 57 patients in the study (mean age = 28.1 years [range = 6-59], 54.4% female, 80.7% white), 49 were included in the primary pharmacokinetic analyses. Diazepam pharmacokinetic profilly. Diazepam nasal spray safety was consistent with the profile of diazepam. © 2020 The Authors.

Genotypes with good canning quality withstand the canning process while remaining intact with good appearance, but canning protocols used by breeders typically involve long processing times that may overcook some genotypes. The goal of this study was to identify whether cooking time influences canning quality in dry beans and whether reducing processing time could improve canning quality of fast-cooking genotypes. RESULTS A set of 20 yellow bean genotypes including Ervilha, PI527538, and 18 derived recombinant inbred lines were selected for their varied cooking times. By comparing the genotypes processed across 5 retort times, differences in canning quality were identified. All genotypes performed better when processed for less time than the standard 45 mins, but canning quality was highest at 10 mins for fast and medium cooking genotypes and 15 mins for slow cooking genotypes.
