Spontaneous Healing of a Posteriorly Displaced Lateral Meniscus Bucket-Handle Tear in a Multiligament Knee Injury
Authors: Green Joshua S. , Seddio Anthony E. , Roybal Dominic , Moran Jay , Katz Lee D. , Medvecky Michael J. 
Published: February 2023

Case:
Bucket-handle meniscus tears (BHMTs) typically involve the medial meniscus and often occur with concomitant rupture of the anterior cruciate ligament. We report an unusual case of a polytrauma patient who sustained a bicruciate multiligament knee injury (MLKI) with a posteriorly displaced lateral BHMT that spontaneously healed after reduction of the fragment. At the 2-year follow-up, the lateral meniscus was clinically stable without pain.

Conclusion:
A lateral BHMT with a posteriorly displaced fragment produced an atypical magnetic resonance imaging presentation in a bicruciate MLKI. Meniscal repair was aborted because of extravasation and concerns of compartment syndrome, but spontaneous healing occurred after fragment reduction.

» Benzoyl peroxide (BPO) 5% has been shown to reduce Cutibacterium acnes load on the skin. BPO 5% with miconazole nitrate (MN) 2% may be beneficial, whereas BPO 5% with clindamycin cream 1% to 1.2% does not seem to have additive effects when compared with BPO 5% alone. Chlorhexidine gluconate solutions reduce the total bacterial load on the skin, but do not seem to have a significant effect on C. acnes.» ChloraPrep seems to be the best surgical skin preparation to decrease overall positive skin cultures. Preincisional hydrogen peroxide 3% application has been shown to be a cost-effective practice to inhibit growth of C. acnes. Vancomycin powder before deltopectoral interval closure has antimicrobial effects against C. acnes and is a cost-effective practice. Finally, Bactisure surgical lavage is protective against the formation of biofilms.» IV cefazolin has been shown to be more effective for shoulder arthroplasty infection prophylaxis than antibiotic alternatives such as vancomycin. Thus, patients with a questionable history of penicillin allergy should undergo additional testing.» For shoulder surgery infection prophylaxis, we recommend the use of BPO 5% cream for 5 days preoperatively with chlorhexidine wipes the night before and the morning of surgery. IV cefazolin should be administered perioperatively, and patients with a questionable history of penicillin allergy should be tested. Surgeons should consider preincisional application of hydrogen peroxide 3% for 5 minutes, followed by standard ChloraPrep preparation. Normal saline should be used for preclosure lavage. Finally, application of vancomycin powder deep to the deltopectoral interval closure should be considered.

Abstract

Acute infectious bursal disease (IBD) outbreak caused by virulent IBD virus undermines profitable chicken production in Nigeria. Veterinary clinic-based passive surveillance is carried out by postmortem diagnosis of clinical cases submitted during disease outbreaks. Records of IBD outbreaks from two veterinary hospitals in Maiduguri, Nigeria, were extracted among all disease outbreaks in chicken flocks in the period 2008-2018. Data showed that IBD outbreaks occurred in 493 (7.6%, [95% CI: 7.0-8.3%]) out of 6,486 disease outbreaks in chicken flocks within the period. The year-specific prevalence of outbreaks varied from 1.6% (95% CI: 0.9-2.3%) to 17.3% (95% CI: 12.9-21.7%) and fitted a linear trend (r = -0.73; P<0.01) over the years, with significant (P<0.001) association with the years. The chicken-type-specific prevalence varied significantly (P < 0.05) with 25.0% in Noilers (dual-purpose), 7.2% in broilers, 7.1% in layers, 9.1% in local chickens (9.1%) and 17.4% in exotic cockerels. The ages of chickens at the time of outbreaks were 2-27 weeks; modal age was 4-5 weeks while mean age was 5.0±1.7 weeks. The mortality rate was 12.6% (95% CI: 5.9-16.2) out of total flock size of 38,485 in 2015-2018. Specific lesions for diagnosis of acute IBD during surveillance were acute exudative inflammatory swelling of bursa of Fabricius [+/-hemorrhages] (90.9%), along with hemorrhages in thigh, leg and/or breast muscles (72.2%), mucosal hemorrhages at proventriculus-ventriculus junction [+/- enteritis] (24.9%), and nephropathy (7.7%); but few cases lacked bursal swelling (9.1%). Thus, acute IBD outbreak in chickens was endemic with time-related risk factors unaccounted for during passive surveillance.

Authors: Kassaw Moges Mengstu 
Published: February 2023

Abstract
The objective of this study is to investigate empirically the impact of corporate governance on banks’ financial performance in Ethiopia using panel data over the period 2005-2021. Since the data is secondary in nature, the quantitative approach to research was used to measure the impact of corporate governance mechanisms on banks’ financial performance which is measured by ROA. As well, the Feasible Generalized Least Square (FGLS) estimation was used. The FGLS is preferred to the pooled OLS, fixed effect, and random effect model based on the joint effect of an entity in the pooled, variation across entities has not random and correlated in the random effect model, and heteroscedasticity and serial correlation problem in the fixed effect model. The overall FGLS regression result reveals that the model is significant at a 1% level. The regression analysis that six explanatory variables have been found significant effect on the financial performance of bank firms in Ethiopia, management efficiency and asset quality had a negative significant impact on bank performance, whereas bank size, liquidity ratio, legal reserve, and loan to deposit ratio were positively and significantly affect bank performance.
Finding the needle in the haystack of isokinetic knee data: Random Forest modelling improves return-to-sport information

Published: February 2023

Abstract
Background: The difficulties of rehabilitation after anterior cruciate ligament (ACL) injuries, subsequent return-to-sport (RTS) let alone achieving pre-injury performance are well known. Isokinetic testing is often used to assess strength capacities during that process. The aim of the present applied machine learning (ML) approach was to examine which isokinetic data differentiates athletes post ACL reconstruction and healthy controls.
Data from unilateral concentric and eccentric knee flexor and extensor tests (30°/s, 150°/s) was used to train Random Forest models from 366 male (63 post ACL reconstruction) and 183 female (72 post ACL reconstruction) athletes. Via a cross validation predictive performance was evaluated and accumulated local effects plots analysed the features of the models.
Results: Random Forest showed outstanding predictive performance for male (AUC=0.90, sensitivity=0.76, specificity=0.88) and female (AUC=0.92, sensitivity=0.85, specificity=0.89) athletes. For both male and female athletes, the ten most impactful features on the predictive likelihood of the model either referred to the disadvantageous (injured, non-dominant in control group) leg or to lateral differences. The eccentric hamstring work at 150°/s was identified as the most impactful single parameter.
Conclusion: A ML model trained with parameters from isokinetic knee data discriminated between athletes 6 to 24 months post ACL reconstruction and healthy athletes with high accuracy. We see potential for improving RTS decision making by incorporating and combining measures, which focus on hamstring strength, leg symmetry and contractional work.
Effects of anime characters’ facial expressions on donation behavior during the COVID-19 pandemic

Published: February 2023

Abstract
With the increasing demand for donations via the Internet, virtual agents (VAs) will be increasingly used to motivate people to donate in the future. Previous research suggests that VAs' with facial expressions indicating an emotional response to donations over and above a given minimum threshold may be effective in soliciting donations from people. In this study, we investigated whether VAs could induce human participants to donate a given amount of money encoded as a limit expressed by emotional responses using the dictator game. In contrast to prior works, the results showed that emotional responses had no effect on the amounts donated. We conducted an additional experiment to consider anchoring effects (Experiment 2), donation recipients (Experiments 3, 4, and 5), and social norms (Experiments 4 and 5). The results showed that facial expressions had no effect in any of the experiments. However, in Experiment 4, the amount of donations decreased more for recipients suffering from COVID-19 than children orphand in traffic accidents. In addition, we conducted a meta-analysis to combine the experimental results. These results showed that VAs that displayed facial expressions received an increased amount of donations, although the magnitude of this effect was limited; second, offers to people suffering from COVID-19 tended to decrease more than offers to children orphand in traffic accidents. This suggest that an agent's motivation for requesting donations via emotional expressions may impact the amounts received; these results may have been influenced by the COVID-19 pandemic.

Published: February 2023

Abstract
Background: Maternal malnutrition is widespread throughout the world, with Sub-Saharan Africa and Asia bearing the brunt of the burden. The objective this study was to evaluate the effect of intensive nutrition education and counseling on nutritional status during pregnancy.
Methods and Materials: The study was a one-year two-arm parallel design cluster randomized controlled trial conducted in East Shoa zone, Ethiopia from January 4, 2021, to February 28, 2022. A total of 374 were enrolled in the intervention (n = 185) and control (n = 189) groups. End-line data were collected from 163 women, from each intervention and control group. The intervention package provided was a three counseling sessions by trained midwives, a 3 page take-home brochures prepared in local languages distributed and 18 weekly serial short message texts were delivered. The women in the control group received routine nutrition education from the health facilities. After adjusting for potential confounders, a linear mixed-effects model was used to assess the intervention effect.
Results: After the intervention, the mean mid-upper arm circumference in the intervention group increased by 36% (23.08 Vs 23.44, p < 0.01). Similarly, the proportion of undernutrition in the intervention group was 11% (25% Vs 36%, p = 0.02) lower compared to the control arm. At the end of the trial, women in the intervention arm had significantly better nutritional status than women in the control group (β = 0.47, p < 0.01).
Conclusion: The finding showed that intensive nutrition education and counseling using the health belief model was effective in improving nutritional status and reducing under nutrition among pregnant women. As a result, nutrition education and counseling using HBM constructs, as well as regular reminder messages, should be provided to pregnant women as part of the routine antenatal care service.

Abstract
This study aimed to compare the effects of 8 weeks 11+ warm-up injury prevention program on kinematics and proprioception in adolescent male and female soccer players. forty adolescent soccer players (20 males, 20 females) aged between 14-16 years old were randomly assigned into four groups. The experimental group performed the 11+ program for 8 weeks and the control group did their warm-up program. The kinematic variable in a cutting maneuver was measured using VICON motion analysis and ankle and knees’ proprioception by joint position sense(JPS) was measured using a digital inclinometer. For kinematic variables only significant differences in knee valgus among females 11+ compared with female and male control groups were found (P < 0.05). Moreover, there were significant improvements in joint position sense variables in 11+ groups compared to control groups (P< 0.05). In conclusion, the 11+ program was proven to be a useful warm-up protocol in improving knee valgus and JPS among female and male adolescent soccer players. We suggest adding more training elements to the 11+ program that aimed to enhance the proper alignment of lower extremities which may consequently improve joint kinematics.
Native and exotic species post - dispersal seed predation: a community scale approach
Authors: Campagna Maria Sofia , Barberá Ivan , Morán-López Teresa 
Published: February 2023

Abstract
Seed predation is one of the most important biotic filters that determines whether an exotic species can become part of the community. Rodents are generalist seed consumers whose feeding preferences can affect the exotic species recruitment. Their foraging decisions are often modulated by seed traits, abundance, and the environmental context in which rodents encounter seeds. Besides, the consumption preference for exotic seeds may depend on how different they are from natives. We evaluated the combined effect of species-specific seed size, their relative abundance, and vegetation structure on predation rates of native and exotic plant species in a Patagonian forest, where two species of contrasting seed sizes are naturalized (Prunus cerasus and Rubus ideaeus). We performed a cafeteria experiment in which we offered seeds of native and exotic species in paired plots located in microhabitats with shrub cover or open. In plots located under shrub cover seed predation rates were 2.3 times higher than in open areas. Feeding preferences of rodents were driven by seed size, selecting seeds of intermediate sizes. As result, they strongly avoided large exotic Prunus seeds, but consumed intermediate Rubus seeds at similar rates to natives. Thereby, in our system, size is a strong modulator of post-dispersal predation of exotic seeds and rarity does not confer any advantage to exotics. Low predation rates in open areas suggest that they could be regeneration foci for all species. Future work quantifying recruitment across microhabitats will allow to evaluate if patterns here found have an imprint in the seedling community.

Abstract

Background: Vegetarian (VG) and vegan (VN) diets are becoming increasingly popular among children. These restrictive types of diet remain a concern as they may impair growth and development, although up-to-date epidemiological studies are lacking. Iodine, an essential micronutrient, is of specific concern due to its important role in thyroid gland physiology.
Methods: We collected clinical, anthropometric, and blood/urine parameters of iodine status as well as thyroid function among children following VG (n = 91), VN (n = 75), and omnivores (OM, n = 52), aged 5.4 (± 4.3) years.
Results: We found no significant differences in levels of thyroid-stimulating hormone (TSH), triiodothyronine (fT3), or thyroglobulin (TG) between the groups. Thyroxine (fT4) levels were higher in OM compared to VN (15.00 ± 1.73 vs. 16.17 ± 1.82 pmol/L, p < 0.001). There were strong differences in anti-thyroglobulin antibodies (AhTGc) between groups (OM: 2.54 ± 8.31 vs. VG: 16.24 ± 44.46 vs. VN: 13.93 ± 9.16 UI/L, p < 0.001). Iodine concentration in spot urine (UIC) was highest in OM (195.31 ± 105.28 vs VG: 177.27 ± 155.13 vs. VN: 162.94 ± 163.39 µg/L, p < 0.001). The lowest (5.99 µg/L) but also the highest (991.80 µg/L) levels were measured in VN. 31 VN and 31 VG children met the criteria for iodine deficiency (i.e., UIC < 100 µg/L). Children with regular iodine supplementation had higher UIC (p < 0.001).
Conclusion: We observed a higher prevalence of iodine deficiency in VN and VG group than in OM, with possible impact on thyroidal health (i.e., positivity of antibodies). Further research and new guidelines for iodine supplementation among VG and VN children are therefore warranted.
The earliest fungal plant pathogen ?

Published: February 2023

Abstract
Nowadays Fungi are recognized as integral to well-functioning ecosystems, and their broader impact on earth systems is widely acknowledged. Remarkable early fossil evidence from the Rhynie chert (Scotland, UK) shows that Fungi were already diverse in terrestrial ecosystems over 407-million-years-ago, yet evidence for the occurrence of Dikarya (the subkingdom of Fungi that includes the phyla Ascomycota and Basidiomycota) in this fossilised geothermal site is scant.
Here we used high resolution white light microscopy and confocal laser scanning microscopy to re-examine historic petrographic thin sections of exceptionally well-preserved fossils from the Rhynie chert site. 3D visualizations obtained by confocal laser scanning microscopy were created from the image stacks; this method proved effective for plant tissues and associated fungal remains.
We document a new fungus, Potteromyces asteroxylicola that we attribute to Ascomycota incertae sedis (Dikarya). This fungus colonized the aerial axes and leaf-like appendages of the plant Asteroxylon mackiei (Lycopsida). The fungus is represented by a stroma-like structure and by conidiophores originating in tufts from beneath the cuticle. We show that these caused a reaction in the plant that gave rise to dome-shaped surface projections. This suite of features in the fungus together with the plant reaction tissues provides the earliest unequivocal fossil evidence of a plant pathogenic fungus.
The newly described fungus belongs to an extinct lineage that could serve as a minimum node age calibration point for the Ascomycota as a whole or perhaps for the Dikarya crown group. This also might apply to Paleopyrenomycites devonicus, and to the hymenial layer bearing polysporus asci that was attributed to Prototaxites taiti, both previously documented in the Rhynie chert. Our finding also supports an affiliation to Ascomycota rather than to Basidiomycota for the origin of fungal plant pathogenicity.

Abstract
Challenge 3 of the 2022 NIST additive manufacturing benchmark (AM-Bench) experiments asked modelers to submit predictions for solid cooling rate, liquid cooling rate, time above melt, and melt pool geometry for single and multiple track laser powder bed fusion process using moving lasers. An in-house developed Additive Manufacturing Computational Fluid Dynamics code (AM-CFD) combined with a cylindrical heat source was implemented to accurately predict these experiments. Heuristic heat source calibration was proposed relating volumetric energy density (ψ) based on experiments available in the literature. The parameters of the heat source of the computational model were initially calibrated based on a Higher Order Proper Generalized Decomposition- (HOPGD) based surrogate model. The prediction using the calibrated heat source agreed quantitatively with NIST measurements for different process conditions. A scaling law based on keyhole formation was also utilized in calibrating the parameters of the cylindrical heat source and predicting the challenge experiments. In addition, an improvement on the heat source model was proposed to relate the Volumetric Energy Density (VEDσ) to the melt pool aspect ratio. The model showed further improvement in the prediction of the experimental measurements for the melt pool including cases at higher VEDσ. Overall, it was concluded that the appropriate selection of parameterization scheme along with the heat source model was crucial in the accurate prediction of melt pool geometry and thermal measurements while bypassing the expensive computational simulations that consider increased physics equations.
Cannabidiol Inhibits Neuroinflammatory Responses and Circuit-Associated Synaptic Loss Following Damage to a Songbird Vocal Pre-motor Cortical-Like Region
Authors: Tripson Mark , Litwa Karen , Soderstrom Ken 
Published: February 2023

Abstract
The non-euphorigenic phytocannabinoid cannabidiol (CBD) has been used successfully to treat childhood-onset epilepsies. These conditions are associated with developmental delays that often include vocal learning. Zebra finch song, like language, is a complex behavior learned during a sensitive period of development. Song quality is maintained through continuous sensorimotor refinement involving circuits that control learning and production. Within the vocal motor circuit, HVC is a cortical-like region that when partially lesioned temporarily disrupts song structure. We previously found CBD (10 mg/kg/day) improves post-lesion vocal recovery. The present studies were done to understand mechanisms underlying CBD vocal protection. We found CBD-improved vocal recovery is accompanied by reduced expression of inflammatory mediators and oxidative stress markers. These effects were associated with regionally-reduced expression of the microglia marker TMEM119. As microglia are key regulators of synaptic reorganization, we measured synapse densities, finding significant lesion-induced circuit-wide decreases that were largely reversed by CBD. Synaptic protection was accompanied by NRF2 activation and BDNF/ARC/ARG3.1/MSK1 expression implicating mechanisms important to song circuit node mitigation of oxidative stress and promotion of synaptic homeostasis. Our findings indicate CBD improves post-lesion recovery of a complex learned behavior through an array of neuroprotective processes consistent with modulation of multiple cell signaling systems.
