Adjusting the Potential Field Source Surface Height Based on Magnetohydrodynamic Simulations
Authors: Huang Zhenguang , Tóth Gábor , Huang Jia , Sachdeva Nishtha , van der Holst Bart , Manchester Ward B. 
Published: April 2024

Abstract
A potential field solution is widely used to extrapolate the coronal magnetic field above the Sun’s surface to a certain height. This model applies the current-free approximation and assumes that the magnetic field is entirely radial beyond the source surface height, which is defined as the radial distance from the center of the Sun. Even though the source surface is commonly specified at 2.5 R

s
(solar radii), previous studies have suggested that this value is not optimal in all cases. In this study, we propose a novel approach to specify the source surface height by comparing the areas of the open magnetic field regions from the potential field solution with predictions made by a magnetohydrodynamic model, in our case the Alfvén Wave Solar atmosphere Model. We find that the adjusted source surface height is significantly less than 2.5 R

s
near solar minimum and slightly larger than 2.5 R

s
near solar maximum. We also report that the adjusted source surface height can provide a better open flux agreement with the observations near the solar minimum, while the comparison near the solar maximum is slightly worse.
Domitius lusitanicus (Araneae, Nesticidae) - an umbrella species for the conservation of troglobionts in the Estremenho Karst Massif, Portugal
Authors: Alves Tomás , Reboleira Ana Sofia P. S. 
Published: April 2024

Domitius lusitanicus (Fage, 1931) is a troglobiont spider, endemic from caves in the largest karst massif in Portugal, the Estremenho. It was the first described cave-adapted species from Portugal, but the male of the species was only described in 1988.
Over the last two decades, the knowledge on the distribution of D. lusitanicus increased significantly. We assess the conservation status of D. lusitanicus, providing new information on its extent of occurrence and the anthropogenic threats, and present a IUCN Red List profile. D. lusitanicus faces various anthropogenic threats, such as habitat loss, agriculture, pollution, and tourism impacts. Despite a large part of its distribution is included in a Natural Park, it expands outside of the areas deemed for protection in the Natura 2000 network. This species has the widest spread distribution of all troglobionts in the Estremenho Massif, therefore it may be used as an umbrella species for the protection of other cave-adapted species of the massif.
Enhanced Total Hip Arthroplasty Education Using Augmented Reality: A Survey From a Tertiary Center
Authors: Ryan Sean P. , Cochrane Niall , Bolognesi Michael P. , Wellman Samuel S. 
Published: April 2024

Background:
For total hip arthroplasty (THA), a new technology in the evolution of computer-assisted surgery has emerged in the form of augmented reality (AR). We sought to determine the impact of AR on resident and fellow education after implementation at an academic teaching center.

Materials and Methods:
The senior author's intraoperative technique allows for the orthopedic trainee to use AR to correct the acetabular component's position after an attempt is made with standard instrumentation. One year after the implementation of this AR method, both resident and fellow trainees were issued an anonymous survey regarding their experience and descriptive statistics were calculated for the results.

Results:
Sixteen trainees responded to the survey. One hundred percent felt the use of AR improved their understanding of acetabular component placement and improved their intraoperative experience. Sixty-nine percent reported feeling there was a small increase in operative time but 25% reported no increase in operative time when using AR. Seventy-five percent of trainees felt that patients benefited from the technology and would be in favor of AR if they were having a THA. The majority of those surveyed reported a desire to use AR in their practice if it is available.

Conclusion:

Computer-assisted surgery has demonstrated variable impacts on orthopedic education. After the implementation of AR at an academic teaching center, all trainees reported it improved their intraoperative experience and their understanding of acetabular component placement. Further studies are needed to determine if AR is able to improve a trainee's component placement. [

Authors: Zhang Dafang , Jupiter Jesse B. , Blazar Philip , Earp Brandon E. , Dyer George S. M. 
Published: April 2024

Background:
Humeral nonunions have devastating negative effects on patients' upper extremity function and health-related quality of life. The objective of this study was to identify factors independently associated with 30-day complication, hospital readmission, and reoperation after surgical treatment of humeral nonunions.

Materials and Methods:

A retrospective case-control study was performed using the American College of Surgeons National Surgical Quality Improvement Program database by querying the
Current Procedural Terminology
codes for patients who underwent humeral nonunion repair from 2011 to 2020. The study outcomes were 30-day complication, hospital readmission, and reoperation.

Results:
Of the 1306 patients in our cohort, 135 patients (10%) developed a complication, 66 patients (5%) were readmitted to the hospital, and 44 patients (3%) underwent reoperation during the 30-day postoperative period. Multivariable logistic regression analysis showed that older age, longer operative time, partially dependent functional status, congestive heart failure, bleeding disorder, and contaminated wound classification were associated with 30-day complication after humeral nonunion repair. Older age and disseminated cancer were associated with 30-day reoperation after humeral nonunion repair. Disseminated cancer was associated with 30-day readmission after humeral nonunion repair.

Conclusion:

Using a large database over a recent 10-year period, we identified demographic and comorbid factors independently associated with episode of care adverse events after humeral nonunion repair. Patients 50 years or older had approximately three times the incidence of complications, readmissions, and reoperations in the first month after humeral nonunion repair compared with patients younger than 50 years. Our findings are relevant for preoperative risk stratification and counseling. [

Shoulder Hemiarthroplasty Is Associated With Higher 30-Day Complication Rates Compared With Total Shoulder Arthroplasty for Glenohumeral Osteoarthritis: A Propensity Score Matched Analysis
Authors: Wyatt Phillip B. , Reiter Charles R. , Satalich James R. , O'Neill Conor N. , Vap Alexander R. 
Published: April 2024

Background:
Anatomical total shoulder arthroplasty (TSA) and shoulder hemiarthroplasty (HA) have both been shown to have good outcomes in patients with osteoarthritis of the glenohumeral joint. However, evidence comparing perioperative complications between these procedures in this population is heterogeneous.

Materials and Methods:
The American College of Surgeons National Surgical Quality Improvement Program database was queried between the years 2012 and 2021 (10 years in total) for records of patients who underwent either TSA or HA for osteoarthritis of the glenohumeral joint. Patients in each group underwent a 1:1 propensity match for demographic variables. Bivariate and multivariate analyses were performed to compare complications and risk factors between these cohorts.

Results:

A total of 4376 propensity-matched patients, with 2188 receiving TSA and 2188 receiving HA, were included in the primary analyses. The HA cohort had a higher rate of any adverse event (7.18% vs 4.8%,
P
=.001), death (0.69% vs 0.1%,
P
=.004), sepsis (0.46% vs 0.1%,
P
=.043), postoperative transfusion (4.62% vs 2.2%,
P
<.001), postoperative intubation (0.5% vs 0.1%,
P
=.026), and extended length of stay (23.77% vs 13.1%,
P
<.001). HA was found to increase the odds of developing these complications when baseline demographics were controlled. Older age (odds ratio, 1.040; 95% CI, 1.021-1.059;
P
<.001) and lower body mass index (odds ratio, 0.949; 95% CI, 0.923-0.975;
P
<.001) increased the odds of having any adverse event in the HA cohort but not in the TSA cohort.

Conclusion:

Compared with TSA, HA appears to be associated with significantly higher rates of 30-day postoperative complications when performed for glenohumeral osteoarthritis. [

Authors: Alkhatatba Mohammad , Alma'aiteh Ala'a , Audat Ziad , Bani Essa Suhaib , Radaideh Ahmad , Mohaidat Ziyad , Ziad Audat Hamzeh , Manasreh Tarek 
Published: April 2024

Background:
Vertebral augmentation including vertebroplasty and kyphoplasty may restore function without interfering with the therapeutic regimen of patients with multiple myeloma. We sought to evaluate the effects of adding multilevel vertebral augmentation to conventional therapy protocols for patients with multiple myeloma.

Materials and Methods:
Forty-four patients recently diagnosed with multiple myeloma were randomly assigned to two groups. One group received multilevel vertebral augmentation (kyphoplasty or vertebroplasty) in addition to conventional therapy (MVA), and the other group received conventional therapy alone (CTA). Patients were evaluated before treatment and at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years after treatment by using the Oswestry Disability Index (ODI), the Stanford Score (SS), and the Spinal Instability Neoplastic Score (SINS).

Results:

The mean ODI, SS, and SINS were nearly equal before treatment, being 34.19 (68.38%), 4.58, and 12.30, respectively, for the MVA group and 32.29 (64.58%), 4.63, and 13.88, respectively, for the CTA group. There were significant differences in the ODI, SS, and SINS between the two groups at all follow-up intervals. The ODI and SINS were statistically significantly different between the two groups (
P
=.020 and
P
<.001, respectively). There was an insignificant difference in SS between the two groups.

Conclusion:

This study found that performing kyphoplasty and vertebroplasty in addition to conventional therapy for patients with multiple myeloma resulted in enhanced morbidity and functional outcomes. [

Authors: Fisher Nina D. , Merrell Lauren A. , Solasz Sara J. , Ganta Abhishek , Konda Sanjit R. , Egol Kenneth A. 
Published: April 2024

Background:

The purpose of this study was to determine if the presence of a standing
Diagnostic and Statistical Manual of Mental Disorders,
Fifth Edition, psychiatric diagnosis is associated with worse outcomes for patients who develop a confirmed fracture-related infection (FRI).

Materials and Methods:
Included patients had open or closed fractures managed with internal fixation and had confirmed FRIs. Baseline demographics, injury information, and outcomes were collected via chart review. All patients who had a diagnosis of psychiatric illness, which included depression, bipolar disorder, anxiety disorder, and schizophrenia, were identified. Patients with and without a psychiatric diagnosis were statistically compared.

Results:

Two hundred eleven patients were diagnosed with a confirmed FRI. Fifty-seven (27.0%) patients had a diagnosis of a psychiatric illness at the time of FRI diagnosis. Patients with a psychiatric diagnosis had a higher rate of smoking (56% vs 40%,
P
=.039) and drug use (39% vs 19%,
P
=.004) and a higher American Society of Anesthesiologists (ASA) classification (2.35±1.33 vs 1.96±1.22,
P
=.038); however, there were no other demographic differences. Clinical outcomes also did not differ between the groups, as patients with an FRI and a psychiatric diagnosis had a similar time to FRI diagnosis, similar confirmatory FRI characteristics, and a similar rate of reoperation. Furthermore, there was no difference between patients with FRI with and without a psychiatric diagnosis regarding rate of infection resolution (89% vs 88%,
P
=.718) or time to final follow-up (20.13±24.93 vs 18.11±21.81 months,
P
=.270).

Conclusion:

The presence of a psychiatric diagnosis does not affect clinical outcomes in the patient population with FRI. This is the first study exploring the impact of psychiatric illness on patient outcomes after a confirmed FRI diagnosis. [

Authors: Adunmo Godwin O. , Taiwo Seyi , Muniru Ibrahim , Busari A.O. 
Published: April 2024

Introduction: Petrol fume contain organic compounds that have been suggested to be endocrine disruptors. There is paucity of data on petrol fume-linked health challenges in Nigeria. Thus, we evaluated the effects of petrol fume exposure on blood levels of reproductive and thyroid hormones among petrol pump station attendants in Kwara state, Nigeria.
Material and Methods: Eighty (80) petrol station attendants and fifty (50) non-occupationally exposed subjects were recruited as controls. Anthropometric indices were taken and fasting blood samples were collected after signing the consent form. Free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), testosterone, follicle stimulating hormone and luteinizing hormone were evaluated using standard techniques.
Results: Average age and BMI of petrol fume-exposed subjects are 27.40±0.419 and 24.98±0.254 respectively and was not different from controls. Elevated FT3 and FT4 were evaluated with a decreased TSH level in the exposed group when compared with controls. In contrast, FSH, LH and testosterone were significantly reduced in exposed group when compared with control.
Conclusion: The result of this study shows that petrol fume toxicants adversely alter thyroid and gonadal functions thereby modulating circulating levels of reproductive and thyroid hormones in male petrol station attendants in Kwara state.

Published: April 2024

Introduction: This study investigated the production of L-lysine using Corynebacterium glutamicum and various leaf extracts (cassava, palm tree, maize, cowpea, cocoyam, and plantain). The study also explored the activities of amylases and proteases, as well as the levels of total soluble proteins, reducing sugars, glucose, flavonoid and phenolic contents, and pH changes.
Materials and Methods: Different treatments (extract, boiled extract, extract + C. glutamicum, boiled extract + C. glutamicum) were examined for their effects on L-lysine concentration. Additionally, the activities of amylases and proteases, as well as levels of total soluble proteins, reducing sugars, glucose, flavonoid and phenolic contents, and pH changes, were analyzed.
Results: Maize leaf extract + C. glutamicum exhibited the highest L-lysine concentration (1.771a±0.1 mg/g), while boiled cassava leaf extract showed the lowest concentration (0.023b±0.1 mg/g). Palm tree leaf extract had significantly higher reducing sugar levels compared to other extracts. Boiled plantain leaf extract fermented by C. glutamicum had the highest total soluble protein level (9.5±0.2 mg/g), while cassava leaf extract had the lowest (2.1±1.2 mg/g).
Conclusion: Submerged fermentation of leaf extracts using C. glutamicum can be utilized for L-lysine production. The study highlights the influence of different leaf extracts and treatments on L-lysine production, as well as on amylase and protease activities, total soluble protein levels, reducing sugars, glucose, flavonoid and phenolic contents, and pH values. These findings provide valuable insights into the potential application of this approach for lysine production.

Disruptive and Familiar Futures of Experiential Learning Theory and High Impact Practices
Authors: Heinrich Bill 
Published: April 2024

This essay responds to and extends an interview with David Kolb, Alice Kolb, and George Kuh who discussed their definitions, research, and foundations of Experiential Learning Theory and High Impact Practices. I describe how the profound influence of ELT and HIPs have effectively disrupted higher education. I observed that institutions are operationalizing ELT and HIPs at an increasing pace without an updated, shared definition, leaving space for a collective agenda to emerge. I conclude with a call for further engagement with key questions and for scholars and practitioners to build the agenda of experiential and engage learning in meaningful and sustainable ways.
