Effects of litter and additional enrichment elements on the occurrence of feather pecking in pullets and laying hens – A focused review

Abstract Severe feather pecking (SFP) is a serious problem in the egg production industry with regard to animal welfare and performance. The multifactorial causes of SFP are discussed in the areas of genetics, feeding, husbandry, stable climate and management. Several studies on the influence of manipulable material on the incidence of SFP in different environments and housing systems have been performed. This review presents current knowledge on the effects of litter and additional enrichment elements on the occurrence of SFP in pullets and laying hens. Because SFP is associated with foraging and feed intake behaviour, the provision of manipulable material in the husbandry environment is an approach that is intended to reduce the occurrence of SFP by adequate exercise of these behaviours. As shown in the literature, the positive effect of enrichment and litter substrate on SFP in a low‐complexity cage environment is evident. On the other hand, consistent results have not been reported on the influence of additional enrichment material in housing systems with litter substrate, which represent the most common type of husbandry in Northwestern Europe. Thus, further research is recommended.
[Mediation Effect of Self-Efficacy on the Relationship between Perceived Self-Management Support and Health-Related Quality of Life among Cancer Survivors].

PURPOSE This study aimed to examine the levels of perceived self-management support, self-efficacy for self-management, and health-related quality of life (HRQoL) in cancer survivors, and to identify the mediating effect of self-efficacy in the relationship between perceived self-management support and HRQoL. METHODS This study used a descriptive correlational design. Two hundred and four cancer survivors who had completed treatment participated in the study. Measurements included the Patient Assessment of Chronic Illness Care Scale, the Korean version of the Cancer Survivors' Self-Efficacy Scale, and the Medical Outcomes Study Short Form-36. Data were analyzed using descriptive statistics, Pearson's correlation coefficient analysis, and multiple regression analysis using Baron and Kenny's method for mediation. RESULTS The mean score for perceived self-management support was 3.35 out of 5 points, self-efficacy was 7.26 out of 10 points, and HRQoL was 65.90 out of 100 points. Perceived self-management support was significantly positively correlated with self-efficacy (r=.29, p<.001) and HRQoL (r=.27, p<.001). Self-efficacy was also significantly correlated with HRQoL (r=.59, p<.001). Furthermore, self-efficacy (β=.55, p<.001) had a complete mediating effect on the relationship between perceived self-management support and HRQoL (Z=3.88, p<.001). CONCLUSION The impact of perceived self-management support on HRQoL in cancer survivors was mediated by self-efficacy for self-management. This suggests that strategies for enhancing self-efficacy in cancer survivors should be considered when developing self-management interventions for improving their HRQoL.
The variation of selective uNGAL levels after robot-assisted partial nephrectomy: Early results of a prospective single center study.

OBJECTIVES Acute kidney injury (AKI) secondary to nephron-sparing surgery represents a significant problem in order to preserve renal function. Since serum creatinine alone underestimates the early detection of AKI several biomarker have been investigated. Neutrophil Gelatinase-Associated Lipocalin (NGAL) is considered a good biomarker for AKI. MATERIALS AND METHODS We report our experience in 28 patients affected by localized renal cell carcinoma and submitted to robot-assisted partial nephrectomy (RAPN). In each patient selective urinary NGAL levels were dosed before surgery, then 2 and 48 hours after the procedure, through a ureteral catheter inserted into the excretory axis of the operated kidney. Moreover, we evaluated split renal function of the preserved renal parenchyma by a 99mTC-DTPA renal scintigraphy, performed before surgery and three months later. RESULTS AKI was diagnosed, according to internationally criteria, in 3 patients (10.7%). The baseline selective urinary NGAL level was 20.02 ng/ml. This level significantly increased after surgery with a selective urinary NGAL level that reached 56.36 ng/ml (p < 0.0001). Moreover, a significant reduction in 99mTC-DTPA clearance of the operated kidneys after three months was detected (p < 0.0001). CONCLUSIONS Selective urinary NGAL assay represent a sensitive biomarker of acute kidney injury after robotic nephron sparing surgery, capable of predicting the functional outcome of the operated kidney.
The Predictive Value of Endpoint Quaking-Induced Conversion in Creutzfeldt-Jakob Disease

ABSTRACT: Creutzfeldt-Jakob disease (CJD) is a fatal neurological illness for which accurate diagnosis is paramount. Real-time quaking-induced conversion (RT-QuIC) is a prion-specific assay with high sensitivity and specificity for CJD. The Canadian endpoint quaking-induced conversion (EP-QuIC) test is similar, but unlike RT-QuIC there is little data regarding its diagnostic utility in clinical practice. In this exploratory predictive value analysis of EP-QuIC in CJD, the negative predictive value (NPV) and positive predictive value (PPV) was 100% and 83%, respectively, with one false-positive result identified. Re-testing this sample with an optimized EP-QuIC protocol eliminated this false-positive result, leading to a PPV of 100%. RÉSUMÉ: La valeur prédictive de la méthode diagnostique dite de conversion provoquée par tremblement au point final dans le cas de la maladie de Creutzfeldt-Jakob. La maladie de Creutzfeldt-Jakob (MCJ) est une maladie neurologique qui entraîne à terme un décès et pour laquelle l’établissement d’un diagnostic précis est primordial. La conversion provoquée par tremblement en temps réel (RT-QuIC en anglais) est une méthode diagnostique qui repose sur la détection de la protéine prion. Dans le cas de la MCJ, cette méthode est réputée posséder une sensibilité et une spécificité élevées. La méthode canadienne dite de conversion provoquée par tremblement au point final (EP-QuIC en anglais) se veut similaire mais, à la différence de la RT-QuIC, il existe peu de données en ce qui concerne son utilité diagnostique dans le cadre d’une pratique clinique. Dans cette analyse prédictive exploratoire de la EP-QuIC en lien avec la MCJ, la valeur prédictive négative (VPN) et la valeur prédictive positive (VPP) ont été respectivement de 100 % et de 83 %, un seul résultat faux-positif ayant été identifié. Le fait de soumettre notre échantillon à un nouveau test effectué à l’aide d’un protocole d’EP-QuIC optimisé a permis d’éliminer ce résultat faux-positif, ce qui a débouché sur une VPP de 100 %.
Patient Attitudes and Their Awareness Towards Skin Cancer–Related Apps: Cross-Sectional Survey

Background In the emerging era of digitalization and electronic health, skin cancer–related apps represent useful tools to support dermatologic consultation and examination. Yet, little is known about how patients perceive the value of such apps. Objective The aim of this study was to investigate patient attitudes and their awareness toward skin cancer–related apps. Methods A cross-sectional study including 200 patients from the oncological outpatient unit was conducted at the University Hospital (LMU Munich, Germany) between September and December 2018. Patients were asked to complete a self-administered questionnaire on the popularity and usefulness of health-related and skin cancer–related apps. A descriptive analysis was performed with the expression of categorical variables as frequencies and percentages. For continuous variables, the median and range were indicated. Contingency tables and chi-square tests were performed to investigate associations between sociodemographic data and selected items of the questionnaire. Results A total of 98.9% (195/197) of patients had never used skin cancer–related apps or could not remember. In 49.7% (93/187) of cases, patients were unsure about the usefulness of skin cancer apps, whereas 42.6% (78/183) thought that skin cancer apps could supplement or support the professional skin examination performed by a physician. However, 47.9% (90/188) were interested in acquiring more information by their dermatologists about skin cancer apps. Young age (P=.002), male gender (P=.02), a previous history of melanoma (P=.004), and higher educational level (P=.002) were significantly associated with a positive attitude. Nevertheless, 55.9% (105/188) preferred a printed patient brochure on skin cancer to downloading and using an app. Conclusions The experience and knowledge of skin cancer–related apps was surprisingly low in this population, although there was a high general interest in more information about such apps. Printed patient brochures were the preferred information source.
An Intermolecular π-Stacking Interaction Drives Conformational Changes Necessary to β-Barrel Formation in a Pore-Forming Toxin

A unique feature of the CDC/MACPF/SNTX (cholesterol-dependent cytolysin/membrane attack complex perforin/stonefish toxin) superfamily of pore-forming toxins is that the β-strands that comprise the β-barrel pore are derived from a pair of α-helical bundles. These studies reveal the molecular basis by which the formation of intermolecular interactions within the prepore complex drive the disruption of intramolecular interactions within each monomer of the prepore to trigger the α-helical–to–β-strand transition and formation of the β-barrel pore. ABSTRACT The crystal structures of the soluble monomers of the pore-forming cholesterol-dependent cytolysins (CDCs) contain two α-helical bundles that flank a twisted core β-sheet. This protein fold is the hallmark of the CDCs, as well as of the membrane attack complex/perforin immune defense proteins and the stonefish toxins. To form the β-barrel pore, a core β-sheet is flattened to align the membrane-spanning β-hairpins. Concomitantly with this conformational change, the two α-helical bundles that flank the core β-sheet break their restraining contacts and refold into two membrane-spanning β-hairpins of the β-barrel pore. The studies herein show that in the monomer structure of the archetype CDC perfringolysin O (PFO), a conserved Met-Met-Phe triad simultaneously contributes to maintaining the twist in this core β-sheet, as well as restricting the α-helical–to–β-strand transition necessary to form one of two membrane-spanning β-hairpins. A previously identified intermolecular π-stacking interaction is now shown to disrupt the interactions mediated by this conserved triad. This is required to establish the subsequent intermolecular electrostatic interaction, which has previously been shown to drive the final conformational changes necessary to form the β-barrel pore. Hence, these studies show that the intermolecular π-stacking and electrostatic interactions work in tandem to flatten the core β-sheet and initiate the α-helical–to–β-strand transitions to form the β-barrel pore.

Multiscale Structure Tensor for Improved Feature Extraction and Image Regularization

Regularization methods are used widely in image selective smoothing and edge preserving restoration of noisy images. Traditional methods utilize image gradients within regularization function for controlling the smoothing and can produce artifacts when noise levels are higher. In this paper, we consider a robust image adaptive exponent driven regularization for filtering noisy images with salient feature preservation. Our spatially adaptive variable exponent function depends on a continuous switch based on the eigenvalues of structure tensor which identifies noisy edges, and corners with higher accuracy. Structure tensor eigenvalues encode various image features and we consider a spatially varying continuous map which provides multiscale edge maps of natural images. By embedding the structure tensor-based exponent in a well-defined regularization model, we obtain denoising filters which are capable of obtaining good feature preserving image restoration. The GPU-based implementation computes the edge map in real time at 45–60 frames/s depending on the GPU card. Multiscale structure tensor-based spatially adaptive variable exponent provides reliable edge maps and compared with standard edge detectors it is robust under various noisy conditions. Moreover, filtering based on the multiscale variable exponent map method outperforms L0 sparse gradient-based image smoothing and related filters.
Distress Tolerance and Symptom Severity as Mediators of Symptom Validity Failure in Veterans With PTSD.

OBJECTIVE Performance validity tests (PVTs) and symptom validity tests (SVTs) are necessary in clinical and research contexts. The extent to which psychiatric distress contributes to failure on these tests is unclear. The authors hypothesized that the relation between posttraumatic stress disorder (PTSD) and validity would be serially mediated by distress tolerance and symptom severity. METHODS Participants included 306 veterans, 110 of whom met full criteria for current PTSD. PVTs included the Medical Symptom Validity Test (MSVT) and b Test. The Structured Inventory of Malingered Symptomatology (SIMS) was used to measure symptom validity. RESULTS MSVT failure was significantly and directly associated with PTSD severity (B=0.05, CI=0.01, 0.08) but not distress tolerance or PTSD diagnosis. b Test performance was not significantly related to any variable. SIMS failure was significantly associated with PTSD diagnosis (B=0.71, CI=0.05, 1.37), distress tolerance (B=-0.04, CI=-0.07, -0.01), and symptom severity (B=0.07, CI=0.04, 0.09). The serial mediation model significantly predicted all SIMS subscales. CONCLUSIONS PTSD severity was associated with failing a memory-based PVT but not an attention-based PVT. Neither PVT was associated with distress tolerance or PTSD diagnosis. SVT failure was associated with PTSD diagnosis, poor distress tolerance, and high symptomatology. For veterans with PTSD, difficulty managing negative emotional states may contribute to symptom overreporting. This may reflect exaggeration or an inability to tolerate stronger negative affect, rather than a "cry for help. "
Delayed Cord Clamping versus Early Cord Clamping in Elective Cesarean Section: A Randomized Controlled Trial

Background: Delaying cord clamping is recommended in order to assure placental transfusion. However, the evidence on cord management in elective cesarean section (CS) is limited. Objective: To compare delayed cord clamping (DCC) with early cord clamping (ECC) with regard to postnatal adaptation in neonates born through elective CS. Methods: All neonates born ≥39 weeks’ gestation born through elective CS were assigned to either the DCC or the ECC arm at a 1:1 ratio according to a computer-generated, randomized sequence. The primary outcome was the hematocrit at day 2 of life. Secondary outcomes included: preductal oxygen saturation and heart rate during the first 10 min of life; transcutaneous bilirubin at day 3; and neonatal blood pressures in the first 3 days of life. Additional outcomes included: time to first spontaneous breath; temperature at admission to normal nursery; weight at discharge; and maternal blood losses. Results: Eighty neonates were randomized to the DCC (n = 40) or the ECC (n = 40) arm. The hematocrit at day 2 was significantly higher in the DCC arm than in the ECC arm (mean difference: 6%; 95% CI 3–8; p < 0.0001). The secondary outcome measures were not statistically different between the two arms. No infants needed phototherapy for hyperbilirubinemia during their hospital stay. Conclusions: Delaying cord clamping beyond 60 s increases the hematocrit at day 2 in neonates born through elective CS, without affecting maternal blood losses. Our findings suggest that DCC should be recommended in elective CS, but further studies are warranted to assess long-term outcomes.
The Impact of Equine-Assisted Therapy on Equine Behavioral and Physiological Responses

Simple Summary Equine-assisted therapies (EATs) are often applied to patients with different types of either mental or physical conditions. The increasing application of EATs has induced interest in the scientific community about equine well-being during these therapies. This study aimed to investigate whether equine-assisted therapy (EAT) creates negative or positive emotions in horses and the influence of patients’ therapy expectations (one group of patients had physical and psychological expectations, and one group of patients had only psychological expectations) on horses’ behavioral and physiological responses. We observed 58 pairs (patient–horse) during EAT sessions and when the horses were at rest. Then, we compared the horses’ behavioral and physiological responses between the different periods of therapy and among the groups of patients. Our results suggested that the EAT in this study was neither a negative nor a positive event. EATs with patients who had both physical and psychological expectations were more challenging for horses than those with patients who had only psychological expectations. Further research on EAT should focus on providing horses with positive stimulation and reinforcement to understand whether a positive association with EAT can be created. Abstract Equine-assisted therapies (EATs) have been widely used in the treatment of patients with mental or physical conditions. However, studies on the influence of equine-assisted therapy (EAT) on equine welfare are very recent, and the need for further research is often highlighted. The aim of this study was to investigate whether EAT creates negative or positive emotions in horses, and the influence of patients’ expectations (one group of patients had physical and psychological expectations and one group of patients had only psychological expectations) on horses’ emotional responses. Fifty-eight pairs (patient–horse) were involved in this study. Behaviors and heart rate variability (HRV) data were collected during a resting phase, a preparation phase in which the patients brushed and saddled the horse, and a working phase. Behaviors and HRV were compared between phases and among the groups of patients. Our results suggested that the EAT in this study was neither a negative nor a positive event. EATs with patients who had both physical and psychological expectations were more challenging for horses than those with patients who had only psychological expectations. Further research should focus on providing horses with positive stimulation and reinforcement to understand whether a positive association with EAT can be achieved.
Effect of Aerobic and Resistance Exercise on Cardiac Adipose Tissues: Secondary Analyses From a Randomized Clinical Trial.

Importance Epicardial and pericardial adipose tissues are emerging as important risk factors for cardiovascular disease, and there is a growing interest in discovering strategies to reduce the accumulation of fat in these depots. Objective To investigate whether a 12-week endurance or resistance training intervention regulates epicardial and pericardial adipose tissue mass. Design, Setting, and Participants Secondary analysis of a randomized, assessor-blinded clinical trial initiated on August 2016 and completed April 2018. This single-center, community-based study included 50 physically inactive participants with abdominal obesity. Interventions Participants were randomized to a supervised high-intensity interval endurance training (3 times a week for 45 minutes), resistance training (3 times a week for 45 minutes), or no exercise (control group). Main Outcomes and Measures Change in epicardial and pericardial adipose tissue mass assessed by magnetic resonance imaging, based on a prespecified secondary analysis plan including 3 of 5 parallel groups. Results Of 50 participants (mean [SD] age, 41 [14] years, 10 men [26%]; mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 32 [5]), 39 [78%] completed the study. Endurance training and resistance training reduced epicardial adipose tissue mass by 32% (95% CI, 10%-53%) and 24% (95% CI, 1%-46%), respectively, compared with the no exercise control group (56% [95% CI, 24%-88%]; P = .001 and 48% [95% CI, 15%-81%]; P < .001, respectively). While there was a nonsignificant reduction in pericardial adipose tissue mass after endurance training (11% [95% CI, -5% to 27%]; P = .17), resistance training significantly reduced pericardial adipose tissue mass by 31% (95% CI, 16%-47%; P < .001) when compared with the no exercise control group. Compared with the no exercise control group, there was an increase in left ventricular mass by endurance (20 g [95% CI, 11%-30%]; P < .001) and resistance training (18 g [95% CI, 8%-28%]; P < .001). Other cardiometabolic outcomes remained unchanged after the 12-week trial period. Conclusions and Relevance In individuals with abdominal obesity, both endurance and resistance training reduced epicardial adipose tissue mass, while only resistance training reduced pericardial adipose tissue mass. These data highlight the potential preventive importance of different exercise modalities as means to reduce cardiac fat in individuals with abdominal obesity.

Effects of ATP‐competitive and function‐selective ERK inhibitors on airway smooth muscle cell proliferation

Increased airway smooth muscle (ASM) cell mass and secretory functions are characteristics of airway inflammatory diseases, such as asthma. To date, there are no effective therapies to combat ASM cell proliferation, which contributes to bronchoconstriction and airway obstruction. Growth factors such as platelet‐derived growth factor (PDGF) and the activation of the ERK1/2 are major regulators of ASM cell proliferation and airway remodeling in asthma. However, given the ubiquitous expression and multiple functions of ERK1/2, complete inhibition of ERK1/2 using ATP‐competitive inhibitors may lead to unwanted off‐target effects. Alternatively, we have identified compounds that are designed to target substrate docking sites and act as function‐selective inhibitors of ERK1/2 signaling. Here, we show that both function‐selective and ATP‐competitive ERK1/2 inhibitors are effective at inhibiting PDGF‐mediated proliferation, collagen production, and IL‐6 secretion in ASM cells. Proteomic analysis revealed that both types of inhibitors had similar effects on reducing proteins related to TGF‐β and IL‐6 signaling that are relevant to airway remodeling. However, function‐selective ERK1/2 inhibitors caused fewer changes in protein expression compared with ATP‐competitive inhibitors. These studies provide a molecular basis for the development of function‐selective ERK1/2 inhibitors to mitigate airway remodeling in asthma with defined regulation of ERK1/2 signaling. —Defnet, A.
