Abstract
This experiment was conducted to evaluate potential replacements for pharmacological levels of Zn (provided by Zn oxide), such as diet acidification (sodium diformate) and low dietary crude protein (CP: 21 vs 18%) on nursery pig performance and fecal dry matter (DM). A total of 360 weaned pigs (Line 200 × 400, DNA, Columbus, NE; initially 5.90 ± 0.014 kg) were used in a 42-d growth study. Pigs were weaned at approximately 21 d of age and randomly assigned to pens (five pigs per pen). Pens were then allotted to one of eight dietary treatments with nine pens per treatment. Experimental diets were fed in two phases: phase 1 from weaning to day 7 and phase 2 from days 7 to 21, with all pigs fed the same common diet from days 21 to 42. The eight treatment diets were arranged as a 2 × 2 × 2 factorial with main effects of Zn (110 mg/kg from days 0 to 21 or 3,000 mg/kg from days 0 to 7, and 2,000 mg/kg from days 7 to 21), diet acidification, (without or with 1.2% sodium diformate), and dietary CP (21% or 18%, 1.40% and 1.35% in phases 1 and 2 vs. 1.20% standardized ileal digestible Lys, respectively). Fecal samples were collected weekly from the same three pigs per pen to determine DM content. No 2- or 3-way interactions (P &gt; 0.05) were observed throughout the 42-d study for growth performance; however, there was a Zn × acidifier × CP interaction (P &lt; 0.05) for fecal DM on day 7 and for the overall average of the six collection periods. Reducing CP without acidification or pharmacological levels of Zn increased fecal DM, but CP had little effect when ZnO was present in the diet. From days 0 to 21, significant (P &lt; 0.05) main effects were observed where average daily gain (ADG) and gain:feed (G:F) increased for pigs fed pharmacological levels of Zn, sodium diformate, or 21% CP (P &lt; 0.065). In the subsequent period (days 21 to 42) after the experimental diets were fed, there was no evidence of difference in growth performance among treatments. Overall (days 0 to 42), main effect tendencies were observed (P &lt; 0.066) for pigs fed added Zn or sodium diformate from days 0 to 21, whereas pigs fed 21% CP had greater G:F than those fed 18% CP. Pig weight on day 42 was increased by adding Zn (P &lt; 0.05) or acidifier (P &lt; 0.06) but not CP. In summary, none of the feed additives had a major influence on fecal DM, but dietary addition of pharmacological levels of Zn or sodium diformate independently improved nursery pig performance.
The role of iliocapsularis in hip pathology: a scoping review
Authors: Saito Masayoshi , Khokher Zakir H , Kuroda Yuichi , Khanduja Vikas 
Published: September 2021

ABSTRACT
The iliocapsularis is a relatively unheard-of muscle, located deep in the hip covering the anteromedial capsule of the hip joint. Little is known about this constant muscle despite its clinical relevance. The aims of this scoping review are to collate the various research studies reporting on the detailed anatomy and function of iliocapsularis and to demonstrate how inter-individual differences in iliocapsularis can be used as a clinical adjunct in guiding diagnosis and treatment of certain hip joint pathologies. A computer-assisted literature search was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our review found 13 studies including 384 cases meeting our inclusion criteria. About 53.8% of the studies involved human cadavers. The current scoping review indicates the relevant anatomy of the iliocapsularis, being a small muscle which arises from the inferior border of the anterior inferior iliac spine and anteromedial capsule of the hip joint, inserting distal to the lesser trochanter. Therefore, based upon these anatomical attachments, iliocapsularis acts as a dynamic stabilizer by tightening the anterior capsule of the hip joint. Implications of this association may be that the muscle is hypertrophied in dysplastic or unstable hips. Determining the size of the iliocapsularis could be of conceivable use in patients with hip symptoms featuring signs of both borderline hip dysplasia and subtle cam-type deformities. Although future research is warranted, this study will aid physicians to understand the clinical importance of the iliocapsularis.

ABSTRACT
The coronavirus disease 2019 pandemic stressed healthcare systems worldwide and exposed major flaws in military and civilian healthcare systems. Landstuhl Regional Medical Center (LRMC) serves as the only military medical center for over 205,000 U.S. service members, beneficiaries, and coalition partners stationed throughout Europe, Africa, and the Middle East. The pandemic response required LRMC leaders to reconfigure services to meet pandemic concerns while providing lifesaving care to injured service members from combatant commands. The quickly evolving pandemic challenged leaders to ensure healthcare delivery amid constant change and imperfect information. While LRMC senior leaders developed a strategic pandemic response plan, a multidisciplinary team of nurses, doctors, and technicians collaborated to create an inpatient team to support the dual mission of coronavirus disease 2019 response and casualty care for the warfighter. In this manuscript, we discuss how a multidisciplinary clinical working group at a regional medical center prepared and responded to the pandemic, strategically planned patient care, and ensured support to combatant commands for ongoing forward military operations. Additionally, we share our experiences and lessons learned to inform other military facilities across the medical community and global healthcare systems.

ABSTRACT

Introduction
The COVID-19 pandemic has created challenges for every segment of the U.S. population, including military personnel and their families. The TriService Nursing Research Program’s Military Family Research Interest Group (FIG) formed a collaboration with Blue Star Families, a civilian non-profit organization, to identify potential issues faced by military families during the pandemic.

Data Collection Methods
The Pain Points Poll was introduced online by Blue Star Families, and findings were aggregated weekly between March 18 and May 26, 2020. Volunteer poll respondents were mainly recruited through social media outreach. FIG-informed questions were incorporated in week 4 of polling and focused on workplace environment, financial health, social support, physical and mental health, child behavior, utilization of family care plans, and general well-being. Data were collected to gain real-time insights into the major challenges posed by the pandemic. Findings from FIG-informed questions were collaboratively reviewed and analyzed by FIG and BSF teams. Data-driven recommendations were made to stakeholders to improve processes and reprioritize investments for services that aim to alleviate the impact of COVID-19 on military families.

Findings
A total of 2,895 military family units (i.e., service members and spouses) responded to the poll, a majority of which (88%) represented active duty family units. Although the majority of families (range: 59%-69%) noted no impact to their finances, approximately one in five families endorsed dipping into their savings during the pandemic. A majority of respondents (69.5%) reported taking active measures to support their mental health, endorsing various strategies. Among parents of special needs children, 45% of active duty families and 60% of single-parent service members reported the inability to maintain continued services for their children. A majority of parents with school-aged children (65%) reported child behavioral changes due to their child’s inability to socialize with peers. Among military service members, 41% were concerned about obtaining fair performance evaluations during the crisis.

Conclusions
The COVID-19 pandemic produced significant challenges for military families. Collaboration between military and civilian partners can inform policies and appropriate strategies to mitigate the impact of COVID-19 for military families. The findings presented here provide insight into areas where military families can be supported for optimal outcomes during unprecedented times.
On the bipolarity of Wolf–Rayet nebulae
Authors: Meyer D M-A 
Published: August 2021

ABSTRACT
Wolf–Rayet stars are amongst the rarest but also most intriguing massive stars. Their extreme stellar winds induce famous multiwavelength circumstellar gas nebulae of various morphologies, spanning from circles and rings to bipolar shapes. This study is devoted to the investigation of the formation of young, asymmetric Wolf–Rayet gas nebulae and we present a 2.5-dimensional magneto-hydrodynamical toy model for the simulation of Wolf–Rayet gas nebulae generated by wind–wind interaction. Our method accounts for stellar wind asymmetries, rotation, magnetization, evolution, and mixing of materials. It is found that the morphology of the Wolf–Rayet nebulae of blue supergiant ancestors is tightly related to the wind geometry and to the stellar phase transition time interval, generating either a broadened peanut-like or a collimated jet-like gas nebula. Radiative transfer calculations of our Wolf–Rayet nebulae for dust infrared emission at $24\, \mu \rm m$ show that the projected diffuse emission can appear as oblate, bipolar, ellipsoidal, or ring structures. Important projection effects are at work in shaping observed Wolf–Rayet nebulae. This might call a revision of the various classifications of Wolf–Rayet shells, which are mostly based on their observed shape. Particularly, our models question the possibility of producing pre-Wolf–Rayet wind asymmetries, responsible for bipolar nebulae like NGC 6888, within the single red supergiant evolution channel scenario. We propose that bipolar Wolf–Rayet nebulae can only be formed within the red supergiant scenario by multiple/merged massive stellar systems, or by single high-mass stars undergoing additional, e.g. blue supergiant, evolutionary stages prior to the Wolf–Rayet phase.

Published: August 2021

ABSTRACT
We apply a spectral stacking technique to Westerbork Synthesis Radio Telescope observations to measure the neutral atomic hydrogen content (H i) of nearby galaxies in and around galaxy groups at z &lt; 0.11. Our sample includes 577 optically selected galaxies (120 isolated galaxies and 457 satellites) covering stellar masses between 1010 and 1011.5 M⊙, cross-matched with Yang’s group catalogue, with angular and redshift positions from the Sloan Digital Sky Survey. We find that the satellites in the centres of groups have lower H i masses at fixed stellar mass and morphology (characterized by the inverse concentration index) relative to those at larger radii. These trends persist for satellites in both high-mass ($M_{\rm halo} \gt 10^{13.5}\, h^{-1}\, \mathrm{M}_{\odot }$) and low-mass ($M_{\rm halo} \leqslant 10^{13.5}\, h^{-1}\, \mathrm{M}_{\odot }$) groups, but disappear if we only consider group members in low local density (Σ &lt; 5 gal Mpc−2) environments. Similar trends are found for the specific star formation rate. Interestingly, we find that the radial trends of decreasing H i mass with decreasing group-centric radius extend beyond the group virial radius, as isolated galaxies close to larger groups lack H i compared with those located more than ∼3.0 R180 away from the centre of their nearest group. We also measure these trends in the late-type subsample and obtain similar results. Our results suggest that the H i reservoir of galaxies can be affected before galaxies become group satellites, indicating the existence of pre-processing in the infalling isolated galaxies.

ABSTRACT
Cosmological shock waves are ubiquitous to cosmic structure formation and evolution. As a consequence, they play a major role in the energy distribution and thermalization of the intergalactic medium (IGM). We analyze the Mach number distribution in the Dianoga simulations of galaxy clusters performed with the SPH code gadget-3. The simulations include the effects of radiative cooling, star formation, metal enrichment, supernova, and active galactic nuclei feedback. A grid-based shock-finding algorithm is applied in post-processing to the outputs of the simulations. This procedure allows us to explore in detail the distribution of shocked cells and their strengths as a function of cluster mass, redshift, and baryonic physics. We also pay special attention to the connection between shock waves and the cool-core/non-cool-core (CC/NCC) state and the global dynamical status of the simulated clusters. In terms of general shock statistics, we obtain a broad agreement with previous works, with weak (low-Mach number) shocks filling most of the volume and processing most of the total thermal energy flux. As a function of cluster mass, we find that massive clusters seem more efficient in thermalizing the IGM and tend to show larger external accretion shocks than less massive systems. We do not find any relevant difference between CC and NCC clusters. However, we find a mild dependence of the radial distribution of the shock Mach number on the cluster dynamical state, with disturbed systems showing stronger shocks than regular ones throughout the cluster volume.

ABSTRACT
With the recent release of the Second Gravitational Wave Transient Catalog (GWTC-2), which introduced dozens of new detections, we are at a turning point of gravitational wave astronomy, as we are now able to directly infer constraints on the astrophysical population of compact objects. Here, we tackle the burning issue of understanding the origin of binary black hole (BBH) mergers. To this effect, we make use of state-of-the-art population synthesis and N-body simulations, to represent two distinct formation channels: BBHs formed in the field (isolated channel) and in young star clusters (dynamical channel). We then use a Bayesian hierarchical approach to infer the distribution of the mixing fraction f, with f = 0 (f = 1) in the pure dynamical (isolated) channel. We explore the effects of additional hyperparameters of the model, such as the spread in metallicity σZ and the parameter σsp, describing the distribution of spin magnitudes. We find that the dynamical model is slightly favoured with a median value of f = 0.26, when σsp = 0.1 and σZ = 0.4. Models with higher spin magnitudes tend to strongly favour dynamically formed BBHs (f ≤ 0.1 if σsp = 0.3). Furthermore, we show that hyperparameters controlling the rates of the model, such as σZ, have a large impact on the inference of the mixing fraction, which rises from 0.18 to 0.43 when we increase σZ from 0.2 to 0.6, for a fixed value of σsp = 0.1. Finally, our current set of observations is better described by a combination of both formation channels, as a pure dynamical scenario is excluded at the $99{{\ \rm per\ cent}}$ credible interval, except when the spin magnitude is high.
OlfactionBase: a repository to explore odors, odorants, olfactory receptors and odorant–receptor interactions
Authors: Sharma Anju , Saha Bishal Kumar , Kumar Rajnish , Varadwaj Pritish Kumar 
Published: September 2021

Abstract
Olfaction is a multi-stage process that initiates with the odorants entering the nose and terminates with the brain recognizing the odor associated with the odorant. In a very intricate way, the process incorporates various components functioning together and in synchronization. OlfactionBase is a free, open-access web server that aims to bring together knowledge about many aspects of the olfaction mechanism in one place. OlfactionBase contains detailed information of components like odors, odorants, and odorless compounds with physicochemical and ADMET properties, olfactory receptors (ORs), odorant- and pheromone binding proteins, OR-odorant interactions in Human and Mus musculus. The dynamic, user-friendly interface of the resource facilitates exploration of different entities: finding chemical compounds having desired odor, finding odorants associated with OR, associating chemical features with odor and OR, finding sequence information of ORs and related proteins. Finally, the data in OlfactionBase on odors, odorants, olfactory receptors, human and mouse OR-odorant pairs, and other associated proteins could aid in the inference and improved understanding of odor perception, which might provide new insights into the mechanism underlying olfaction. The OlfactionBase is available at https://bioserver.iiita.ac.in/olfactionbase/.

Published: August 2021

AbstractObjectiveWe sought to determine whether author conflict of interest (disclosed or undisclosed) or industry sponsorship influenced the favorability of reporting of systematic reviews and meta-analyses investigating the use of opioid analgesics for the management of chronic non-cancer pain.MethodsOur search included the MEDLINE (Ovid) and Embase (Ovid) databases. Study sponsorship was determined using the funding statement provided in each systematic review. Author COI information was extracted from the COI disclosure statement. This information was cross-referenced with information available on the CMS Open Payments Database, Dollars for Profs, Google Patents, the United States Patent and Trademark Office (USPTO), and previously published COI disclosures.ResultsEight systematic reviews authored by 83 authors were included. Of these authors, 19 (23.0%) were found to have a COI, of which the majority (17/19; 89.5%) had at least one undisclosed COI. Despite nearly one-quarter of authors having a COI, we found no association between the presence of a COI and the favorability of results (P = 0.64) or conclusions (P = 0.07).ConclusionsCOI are common and frequently undisclosed among systematic review authors investigating opioid analgesics for the management of chronic non-cancer pain. Despite a high prevalence of COI, we did not find that these author-industry relationships had a significant influence on the favorability of results and conclusions; however, our findings should be considered a lower bound estimate of the true influence author COI have on outcomes of pain medicine systematic reviews secondary to the low sample size included in the present study.

Abstract
The cognitive dysmetria theory of psychotic disorders posits that cerebellar circuit abnormalities give rise to difficulties coordinating motor and cognitive functions. However, brain activation during cerebellar-mediated tasks is understudied in schizophrenia. Accordingly, this study examined whether individuals with schizophrenia have diminished neural activation compared to controls in key regions of the delay eyeblink conditioning (dEBC) cerebellar circuit (eg, lobule VI) and cerebellar regions associated with cognition (eg, Crus I). Participants with schizophrenia-spectrum disorders (n = 31) and healthy controls (n = 43) underwent dEBC during functional magnetic resonance imaging (fMRI). Images were normalized using the Spatially Unbiased Infratentorial Template (SUIT) of the cerebellum and brainstem. Activation contrasts of interest were “early” and “late” stages of paired tone and air puff trials minus unpaired trials. Preliminary whole brain analyses were conducted, followed by cerebellar-specific SUIT and region of interest (ROI) analyses of lobule VI and Crus I. Correlation analyses were conducted between cerebellar activation, neuropsychological test scores, and psychotic symptom scores. In controls, the largest clusters of cerebellar activation peaked in lobule VI during early dEBC and Crus I during late dEBC. The schizophrenia group showed robust cortical activation to unpaired trials but no significant conditioning-related cerebellar activation. Crus I ROI activation during late dEBC was greater in the control than schizophrenia group. Greater Crus I activation correlated with higher working memory scores in the full sample and lower positive psychotic symptom severity in schizophrenia. Findings indicate functional cerebellar abnormalities in schizophrenia which relate to psychotic symptoms, lending direct support to the cognitive dysmetria framework.
