A Novel Protocol to Maintain Continuous Access to Thawed Plasma at a Rural Trauma Center.

BACKGROUND Early administration of plasma improves mortality in massively transfused patients, but the thawing process causes delay. Small rural centers have been reluctant to maintain thawed plasma due to waste concerns. Our 254-bed rural level II trauma center initiated a protocol allowing continuous access to thawed plasma and we hypothesized its implementation would not increase waste or cost. METHODS Two units of thawed plasma are continuously maintained in the trauma bay blood refrigerator. After 3 days these units are replaced with freshly thawed plasma and returned to the blood bank for utilization prior to their 5-day expiration date. The blood bank monitors and rotates the plasma. Only trauma surgeons can use the plasma stored in the trauma bay. Wasted units and cost were measured over a 12-month period and compared to the previous 2 years. RESULTS The blood bank thawed 1127 units of plasma during the study period assigning 274 to the trauma bay. When compared to previous years, we found a significant increase in waste (p<0.001) and cost (p=0.020) after implementing our protocol. It cost approximately $125/month extra to maintain continuous access to thawed plasma during the study period.A protocol to maintain thawed plasma in the trauma bay at a rural level II trauma center resulted in a miniscule increase in waste and cost when considering the scope of maintaining a trauma center. We feel this cost is also minimal when compared to the value of having immediate access to thawed plasma. Constant availability of thawed plasma can be offered at smaller rural centers without a meaningful impact on cost.Level III; Economic & Value-based Evaluations.
Sequence variants in genes causing nonsyndromic hearing loss in a Pakistani cohort

Hearing loss or hearing impairment is a clinically and genetically heterogeneous disorder. More than 117 genes were discovered to date in hereditary, nonsyndromic hearing loss (NSHL). Identifying novel gene variants and their frequency in specific populations is valuable for public health and potentially for genetic screening of NSHL.
Plasma amyloid and tau as dementia biomarkers in Down syndrome: Systematic review and meta‐analyses

Individuals with Down syndrome (DS) are at high risk of developing Alzheimer's disease (AD). Discovering reliable biomarkers which could facilitate early AD diagnosis and be used to predict/monitor disease course would be extremely valuable. To examine if analytes in blood related to amyloid plaques may constitute such biomarkers, we conducted meta‐analyses of studies comparing plasma amyloid beta (Aβ) levels between DS individuals and controls, and between DS individuals with and without dementia. PubMed, Embase, and Google Scholar were searched for studies investigating the relationship between Aβ plasma concentrations and dementia in DS and 10 studies collectively comprising >1,600 adults, including >1,400 individuals with DS, were included. RevMan 5.3 was used to perform meta‐analyses. Meta‐analyses showed higher plasma Aβ40 (SMD = 1.79, 95% CI [1.14, 2.44], Z = 5.40, p < .00001) and plasma Aβ42 levels (SMD = 1.41, 95% CI [1.15, 1.68], Z = 10.46, p < .00001) in DS individuals than controls, and revealed that DS individuals with dementia had higher plasma Aβ40 levels (SMD = 0.23, 95% CI [0.05, 0.41], Z = 2.54, p = .01) and lower Aβ42/Aβ40 ratios (SMD = −0.33, 95% CI [−0.63, −0.03], Z = 2.15, p = .03) than DS individuals without dementia. Our results indicate that plasma Aβ40 levels may constitute a promising biomarker for predicting dementia status in individuals with DS. Further investigations using new ultra‐sensitive assays are required to obtain more reliable results and to investigate to what extent these results may be generalizable beyond the DS population.
Screw Fixation of the Posterior Malleolus Fragment in Ankle Fracture

Background: This study aimed to evaluate the outcomes of ankle fractures with posterior malleolus fragments (PMFs) involving <25% of the articular surface treated with or without screw fixation. Methods: Among patients with ankle fractures and PMFs who underwent surgery between March 2014 and February 2017, 62 with type 1 PMFs involving <25% of the articular surface were included. Of these 62 patients, 32 underwent screw fixation for PMFs and lateral and/or medial malleolar fracture fixation (group A) and 30 underwent internal fixation for malleolar fractures without screw fixation for PMFs (group B). Ankle joint alignment and fracture healing were measured using plain radiography and computed tomography (CT). Clinical outcomes were determined using the American Academy of Orthopaedic Surgeons Foot and Ankle Questionnaire, Short Form-36, and American Orthopaedic Foot & Ankle Society Scale. Results: Nonunion was not noted in either group. However, we detected union with a step-off of 2 mm or more in 2 cases from group B. With regard to ankle joint alignment, 1 case in group A and 3 cases in group B showed mild asymmetry of the medial and lateral clear spaces on CT at 12 months. Clinical outcomes at 6 and 12 months after surgery were better in group A than in group B. Conclusion: Screw fixation of PMFs was effective for fracture healing and maintaining ankle alignment. Additionally, it improved short-term clinical outcomes, which we believe was due to stabilization of ankle fractures with PMFs involving <25% of the articular surface. Level of Evidence: Level II, prospective comparative study.
Substrate specificity of IgGs with peroxidase and oxidoreductase activities from sera of patients with systemic lupus erythematosus and multiple sclerosis

The analysis of IgGs to protect humans from oxidative stress through oxidation of harmful compounds was carried out. We have compared here for the first time peroxidase (in the presence of H2O2) and oxidoreductase (in the absence of H2O2) activities of IgGs from sera of healthy humans and patients with systemic lupus erythematosus (SLE) and multiple sclerosis (MS). In addition, substrate specificity of SLE and MS IgG preparations in the oxidation of different compounds was analyzed: 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS), 3,3′‐diaminobenzidine (DAB), homovanillic acid (HVA), o‐phenylenediamine (OPD), α‐naphthol, 3‐amino‐9‐ethylcarbazole (AEC), p‐hydroquinone (pHQ), and adrenaline. IgGs of healthy humans and SLE and MS patients oxidized DAB, ABTS, and OPD due to their peroxidase and oxidoreductase activities, while other compounds were substrates of IgGs only in the presence of H2O2: adrenaline was not oxidized by both activities of IgGs. The average SLE IgGs peroxidase activity increased statistically significant in comparison with abzymes from healthy humans in the order (‐fold): OPD (1.2) < DAB (1.7) < α‐naphtol (2.2) ≤ AEC (2.4) < ABTS (4.5) < 5‐ASA (10.6), while with oxidoreductase activity: OPD (1.8) ≤ DAB (2.1‐fold) < ABTS (5.0). Only HVA was oxidized by IgGs with peroxidase activity of healthy donors faster than by SLE (1.3‐fold) and MS abzymes (2.4‐fold). In the oxidation of several substrates, only three IgGs of MS patients were used. The data speak of a tendency to increase the peroxidase and oxidoreductase activities of MS IgGs in comparison with healthy donors, but to a lesser extent: OPD (1.1 to 1.2‐fold) ≤ ABTS (1.2 to 1.8‐fold). It was shown that development of SLE and MS leads to increase in peroxidase and oxidoreductase activities of IgGs toward most of classical substrates. Thus, abzymes can serve as an additional factor of reactive oxygen species detoxification protecting of patients with SLE and MS from some harmful compounds somewhat better than healthy peoples.
Depression and quality of life in older adults on hemodialysis

Objective: Depression is highly prevalent in hemodialysis patients, but few studies have evaluated older hemodialysis patients. The aim of this study was to evaluate the prevalence of depression, its associated factors and its impact on quality of life in an older population on hemodialysis. Methods: This was a cross-sectional study including 173 hemodialysis patients aged 60 years or older in Recife, Brazil. Depression was evaluated using the Mini-International Neuropsychiatric Interview when depressive symptoms (according to the 5-item Geriatric Depression Scale) were present. Quality of life was assessed with the Control, Autonomy, Self-realization and Pleasure Questionnaire (CASP-16). Data were also collected on sociodemographic, laboratory (albumin, parathormone, hemoglobin, and phosphorus) and dialysis (dialysis vintage, vascular access and hemodialysis adequacy) characteristics. Results: Depression was present in 22.5% of the sample. Depressed patients presented low CASP-16 quality of life scores (31.6 vs. 24.2, p < 0.001), twice the odds of albumin levels < 3.8 g/dL (OR 2.36; 95%CI 1.10-5.07; p = 0.027) and higher parathormone levels (OR 1.06; 95%CI 1.00-1.13; p = 0.05). Conclusion: Older hemodialysis patients have a high prevalence of depression. Depressed patients presented poor quality of life, lower serum albumin and higher parathormone levels. Teams dealing with older hemodialysis patients should include depression and quality of life assessments in care protocols.
Prevalence of NAFLD in China: What Did We Learn From the Recent Meta-Analysis?

However, we have several concerns with their findings due to the methods they used to determine and report the prevalence. This article is protected by copyright. All rights reserved.
Metacognition in functional cognitive disorder- a potential mechanism and treatment target

ABSTRACT Introduction: Functional Cognitive Disorder (FCD) is common. Despite this, there is no evidence-based consensus on how to treat FCD. Poor metacognitive ability has been suggested as a key mechanism underlying the disorder. This paper evaluates the proposal that strategies which improve metacognition could provide a mechanistically plausible translational therapy. Methods: We reviewed the existing literature relating to metacognition in FCD, previous strategies to improve metacognitive ability in FCD and whether metacognitive performance can be modulated. Results: Though limited, there is evidence to suggest that metacognition is impaired in FCD. Converging evidence from neuroimaging studies suggests that metacognitive performance can be modulated. The effectiveness of existing strategies to improve metacognition including cognitive training, psychoeducation and lifestyle interventions have been equivocal. Recently, a potential treatment option has emerged in the form of a computer-based metacognitive training paradigm. Conclusions: There is an urgent need for effective treatments in FCD. Impaired metacognition may be a plausible therapeutic target but, in the first instance, further research is required to demonstrate deficits in “local” metacognitive ability in FCD patients when measured objectively. If so, clinical trials of interventions, such as computerised metacognitive training, are required to evaluate their effectiveness in improving FCD symptoms.
Probing the Neural Mechanisms for Distractor Filtering and Their History-Contingent Modulation by Means of TMS

In visual search, the presence of a salient, yet task-irrelevant, distractor in the stimulus array interferes with target selection and slows down performance. Neuroimaging data point to a key role of the frontoparietal dorsal attention network in dealing with visual distractors; however, the respective roles of different nodes within the network and their hemispheric specialization are still unresolved. Here, we used transcranial magnetic stimulation (TMS) to evaluate the causal role of two key regions of the dorsal attention network in resisting attentional capture by a salient singleton distractor: the frontal eye field (FEF) and the cortex within the intraparietal sulcus (IPS). The task of the participants (male/female human volunteers) was to discriminate the pointing direction of a target arrow while ignoring a task-irrelevant salient distractor. Immediately after stimulus onset, triple-pulse 10 Hz TMS was delivered either to IPS or FEF on either side of the brain. Results indicated that TMS over the right FEF significantly reduced the behavioral cost engendered by the salient distractor relative to left FEF stimulation. No such effect was obtained with stimulation of IPS on either side of brain. Interestingly, this FEF-dependent reduction in distractor interference interacted with the contingent trial history, being maximal when no distractor was present on the previous trial relative to when there was one. Our results provide direct causal evidence that the right FEF houses key mechanisms for distractor filtering, pointing to a pivotal role of the frontal cortex of the right hemisphere in limiting interference from an irrelevant but attention-grabbing stimulus. SIGNIFICANCE STATEMENT Visually conspicuous stimuli attract our attention automatically and interfere with performance by diverting resources away from the main task. Here, we applied transcranial magnetic stimulation over four frontoparietal cortex locations (frontal eye field and intraparietal sulcus in each hemisphere) to identify regions of the dorsal attention network that help limit interference from task-irrelevant, salient distractors. Results indicate that the right FEF participates in distractor-filtering mechanisms that are recruited when a distracting stimulus is encountered. Moreover, right FEF implements adjustments in distraction-filtering mechanisms following recent encounters with distractors. Together, these findings indicate a different hemispheric contribution of the left versus right dorsal frontal cortex to distraction filtering. This study expands our understanding of how our brains select relevant targets in the face of task-irrelevant, salient distractors.
Strained epitaxial interfaces of metal (Pd, Pt, Au) overlayers on nonpolar CdS (101¯0) surfaces from first-principles

The depositions of (1 1 1) and (1 0 0) overlayers of Pd, Pt and Au on the CdS (1 0 0) surface are studied within epitaxial mismatches of 6%–7%, using spin-polarized density functional theory. For both compressively strained and tensile-strained interfaces, the (1 0 0) overlayers were found to be thermodynamically more stable owing to better interfacial matching, and higher surface uncoordination resulting in higher reactivity. Pt(1 1 1) exhibits slip dislocations even for five-atomic-layer thick Pt slabs. Along with the leading metal-S interaction, the interfacial charge transfers indicate a weak metal-Cd interaction which decreases in strength in the order Pd > Pt ∼ Au. For the same substrate area, the accumulation of electronic charge for Pt overlayers is ∼1.5–2 times larger than that of Pd and Au. The n-type Schottky barriers of Au overlayers with the minimum mismatch are within 0.1 eV of the predictions of Schottky–Mott rule, indicating a relatively ideal, scantily reactive interface structure. This is in clear contrast to the Pt epitaxial overlayers which deviate by 0.6–0.8 eV.
LncRNA CADM1-AS1 serves as a new prognostic biomarker for gastric cancer.

OBJECTIVE To investigate the expression of the long non-coding RNA CADM1-AS1 (lncRNA CADM1-AS1) in gastric cancer and its clinical significance. PATIENTS AND METHODS The real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was performed to detect the expression difference of lncRNA CADM1-AS1 between gastric cancer and its adjacent normal tissues. Then, the correlation between the expression of CADM1-AS1 in gastric cancer and the clinicopathological characteristics was analyzed by the Chi-square test. Moreover, the potential of lncRNA CADM1-AS1 in predicting the prognosis of patients with GC after the operation was assessed by the Log-rank test and the Cox's proportional hazards regression model. RESULTS The expression of lncRNA CADM1-AS1 was significantly decreased in tumor tissues. According to the mean expression of lncRNA CADM1-AS1, the patients were divided into a high expression group and a low expression group, and the expression of lncRNA CADM1-AS1 in gastric cancer was significantly correlated with tumor differentiation, N stage, M stage, and TNM stage. Moreover, the gastric cancer patients with higher expression of lncRNA CADM1-AS1 had a statistically better overall survival (OS) time and progression-free survival (PFS) time. In univariate analyses and multivariate analyses, the expression of lncRNA CADM1-AS1 was an independent prognosis index of patients with gastric cancer. CONCLUSIONS LncRNA CADM1-AS1 might be a new prognostic biomarker for gastric cancer.
Neural evidence for the impact of facial trustworthiness on object processing in a gaze-cueing task in 7-month-old infants

ABSTRACT Humans automatically judge a person’s trustworthiness solely based on facial features and use these judgments to inform subsequent behavior. While recent studies demonstrate that already infants are sensitive to variance in facial trustworthiness, it remains unclear whether this variance also influences subsequent socio-cognitive processes. We investigated event-related brain responses (ERPs) to faces varying in trustworthiness in a gaze-cueing paradigm in 7-month-old infants. Our analysis focused on the ERP responses to cued or un-cued objects shown in isolation after the gaze-cue was presented. We observed an enhanced occipital positive slow wave (PSW) to un-cued compared to cued objects, suggesting a gaze-cueing effect irrespective of facial trustworthiness. Furthermore, objects in the un-cued condition elicited a larger fronto-central Nc when the gaze cue was provided by trustworthy compared to untrustworthy faces. This pattern suggests that while gaze cueing occurs irrespective of facial trustworthiness, allocation of attention, as indexed by modulation of the Nc amplitude, varies as a function of trustworthiness. Taken together, our results show that facial trustworthiness impacts object processing in the context of a gaze cueing paradigm, adding to the notion that it serves as an important social cue from early in ontogeny.
Sleep problems in adolescence are prospectively linked to later depressive symptoms via the cortisol awakening response

Abstract Sleep disturbance is a symptom of and a well-known risk factor for depression. Further, atypical functioning of the HPA axis has been linked to the pathogenesis of depression. The purpose of this study was to examine the role of adolescent HPA axis functioning in the link between adolescent sleep problems and later depressive symptoms. Methods: A sample of 157 17–18 year old adolescents (61.8% female) completed the Pittsburgh Sleep Quality Inventory (PSQI) and provided salivary cortisol samples throughout the day for three consecutive days. Two years later, adolescents reported their depressive symptoms via the Center for Epidemiological Studies Depression Scale (CES-D). Results: Individuals (age 17–18) with greater sleep disturbance reported greater depressive symptoms two years later (age 19–20). This association occurred through the indirect effect of sleep disturbance on the cortisol awakening response (CAR) (indirect effect = 0.14, 95%CI [.02 -.39]). Conclusions: One pathway through which sleep problems may lead to depressive symptoms is by up-regulating components of the body’s physiological stress response system that can be measured through the cortisol awakening response. Behavioral interventions that target sleep disturbance in adolescents may mitigate this neurobiological pathway to depression during this high-risk developmental phase.
Position of Central Vascular Trunk and Shape of Optic Nerve Head in Newborns.

Purpose To investigate the baseline position of the central vascular trunk (CVT) and the characteristics of the optic nerve head (ONH) in newborns. Methods CVT position was evaluated based on fundus images obtained from newborns who had undergone eye-screening examinations. It was then graded according to the optic disc area as follows: grade 1, within central 4%; grade 2, within central 9%; grade 3, within central 16%; grade 4, within central 25%; grade 5, outside central 25% of optic disc area. The direction of the CVT position was determined in cases of grade 2 or more as superior, inferior, nasal, and temporal, relative to the optic disc center. The ovality index and the vertical cup-to-disc ratio were determined as well. Results In 1000 fundus images from 1000 newborns, 87.1% showed grade 1 (95% confidence interval 84.7-88.8), and 10.7% showed grade 2. The most common CVT direction was central (87.1%, grade 1), followed by nasal (11.0%) and inferior (1.2%). The ovality index was 1.28 ± 0.09 (range, 1.01-1.61). The ONH shape was vertically oval and highly uniform. The average vertical cup-to-disc ratio was 0.29 ± 0.13 (range, 0.00-0.67). Conclusions The CVT of newborns was located in the central area of the ONH in most cases. The shape of the optic disc was vertically oval, and very similar among the newborns. Considering the high variability of ONH morphology and the diverse location of the CVT in adults, our result suggests that the shape of the ONH and the CVT position might change during eyeball growth.
Housing Rabbit Does in a Combi System with Removable Walls: Effect on Behaviour and Reproductive Performance

Simple Summary This study focuses on the welfare and reproductive performance of rabbit does housed in individual conventional cages (C) or in different colony cages: simple (does in the group for 100% of the reproductive cycle: C1) or combi (in both individual and group caging: C2). The results showed that C2 had some benefits compared to continuous grouphousing, but both colony systems achieved lower reproductive performance levels than the conventional system. Although C2 showed some improvement on the behaviour of does, the aggressiveness of group-housing the does to establish a rank order was responsible for injuries, higher disease risks, and higher kit mortality. Abstract We evaluated the effects of two types of colony cages, in which rabbit does were always in a group (C1), and where they were in combi cages furnished with removable internal walls to allow both individual and grouphousing (C2), in addition to the control group (C: conventional individual cage), on welfare, reproductive performance, and global efficiency. Forty-eight New Zealand White nulliparous rabbit does underwent artificially insemination (AI) and were divided into three groups, and reared in the different systems for about 1 year. The reproductive rhythm provides AIs at weaning (30d). In the C1 system, does were continuously grouped, while in C2, walls were inserted four days before kindling and removed 1week after it (60% of the timesheet in group). Reproductive traits and behaviour were evaluated during the entire year. The behavioural observations were performed around days 7, 36, and 44, corresponding to the inclusion of the does in the maternal cages, the insertion of walls four days before kindling, and the removal of the walls 1week after parturition in the C2 group, respectively. The percentages of does with severe skin injuries and the distribution of the injuries on different parts of body were also registered. Does reared in conventional cages showed the greatest presence of stereotype behaviours, while the C1 group showed the highest (p < 0.05) incidence of aggressiveness after regrouping (attack, dominance features, and lower allo-grooming) in comparison to the C2 group (17% and 22%, in C2 and C1 does, respectively). Individually caged does achieved the best productive performance (sexual receptivity, fertility, kindling rate, and number of kits born alive and at weaning). The C1 group showed the lowest performance (p < 0.05), whereas C2 showed an intermediate one. Does housed in the combi cage (C2) had higher (p < 0.05) receptivity and fertility rates and higher numbers of kits born alive and at weaning (79.2% and 76.2%; 7.95 and 7.20, respectively) than the C1 group, but lower values (p < 0.05) than does that were individually housed.
