A Survey of Musculoskeletal Disorders in the Orthopaedic Surgeon: Identifying Injuries, Exacerbating Workplace Factors, and Treatment Patterns in the Orthopaedic Community
Authors: Swank Katherine R. , Furness Jamie E. , Baker Erin , Gehrke Corinn K. , Rohde Rachel 
Published: May 2022

Introduction:
As demand for orthopaedic care increases, the orthopaedic community must preserve access to skilled physicians. Workplace hazards and related injuries or conditions contribute to musculoskeletal (MSK) stress on orthopaedic surgeons, which can lead to undesirable medical leaves of absence or early retirement. The purpose of this study was to identify and characterize work-related and non–work-related MSK conditions that affect orthopaedic surgeons and differential injury patterns among male and female surgeons. This study hypothesized that MSK conditions would be exacerbated by work, correlate with age, and show gender-based disparities. Identifying MSK conditions and associated workplace hazards may ultimately help guide preventive or protective efforts.

Methods:
Following IRB and society approvals, a modified 15-question physical discomfort survey was emailed to a randomized selection of American Academy of Orthopaedic Surgeons (AAOS) members and all Ruth Jackson Orthopaedic Society members. Data were deidentified and merged by AAOS; analyses were performed by the authors.

Results:
Most surgeons reported at least one MSK condition (86%; 95% male versus 82% female, P = 0.317), with an average of two conditions per surgeon. Low back pain (56%) and neck pain (42%) were the two most common conditions reported. Male surgeons were more likely to report medial epicondylitis (P = 0.040), lateral epicondylitis (P ≤ 0.001), low back pain (P = 0.001), and lumbar radiculopathy (P = 0.001); however, male respondents were significantly older than female respondents (57 versus 43 years, P ≤ 0.0001), and some conditions were age-correlated. Most respondents reported at least one work-attributed MSK condition (64%; 68% male versus 62% female, P = 0.806). Caseload was not associated with an increased number of work-related MSK conditions; yet, 60% of surgeons reported that work worsened symptoms. Surgical treatment was sought most often for lumbar radiculopathy (6%) and carpal tunnel syndrome (6%). Sixty-nine leaves of absence were reported; most less than 1 month (55%). Exacerbating workplace factors included positioning (patient/surgeon), instruments, and personal protective equipment.

Discussion:
Work-related MSK conditions are common among orthopaedic surgeons. Greater awareness of potential workplace-related hazards and conditions is needed to address and mitigate negative MSK health effects on orthopaedic surgeons.

Dispelling the Myth of a Pandemic of the Unvaccinated
Authors: McLeod Deanna , Martins Ilidio , Pelech Stephen , Beck Ceilidh , Shaw Christopher A 
Published: May 2022

We have reanalyzed the Ontario Science Table data on hospitalizations for COVID-19 in COVID-19 vaccinated versus unvaccinated patients admitted to hospital during various waves of the pandemic. In spite of the Ontario Science Table and the mass media claims that the unvaccinated were the dominant population being hospitalized, a more rigorous evaluation of the existing data shows that this narrative is not correct for the latter waves of COVID-19. We identify a series of methodological issues that may have led to their conclusions and why such issues may have resulted in policies that have been largely ineffective.
Memories of a Theoretical Physicist
Authors: Polchinski Joseph 
Published: May 2022

A groundbreaking theoretical physicist traces his career, reflecting on the successes and failures, triumphs and insecurities of a life cut short by cancer.
The groundbreaking theoretical physicist Joseph Polchinski explained the genesis of his memoir this way: “Having only two bodies of knowledge, myself and physics, I decided to write an autobiography about my development as a theoretical physicist.” In this posthumously published account of his life and work, Polchinski (1954–2018) describes successes and failures, triumphs and insecurities, and the sheer persistence that led to his greatest discoveries. Writing engagingly and accessibly, with the wry humor for which he was known, Polchinski gives theoretical physics a very human face.
Polchinski, famous for his contributions to string theory, may have changed the course of modern theoretical physics, but he was a late bloomer—doing most of his important work after the age of forty. His death from brain cancer at sixty-three cut short a career at its peak. Working on the memoir after his diagnosis, using a text-to-speech algorithm because he could no longer read words on a page, he was able to recapitulate his entire career, down to the details of problems he had worked on. For Polchinski, physics went deeper than words.
This edition includes photographs from Polchinski's professional and family life, as well as physics explainer boxes, other technical edits, and bibliographic notes by his former student Ahmed Almheiri, a foreword by Andrew Strominger, and an afterword by his wife Dorothy Chun and sons Steven and Daniel.

Background:Few studies have assessed the role of individual plasma cholesterol levels in the association between egg consumption and the risk of cardiovascular diseases. This research aims to simultaneously explore the associations of self-reported egg consumption with plasma metabolic markers and these markers with the risk of cardiovascular disease (CVD).Methods:Totally 4778 participants (3401 CVD cases subdivided into subtypes and 1377 controls) aged 30–79 were selected based on the China Kadoorie Biobank. Targeted nuclear magnetic resonance was used to quantify 225 metabolites in baseline plasma samples. Linear regression was conducted to assess associations between self-reported egg consumption and metabolic markers, which were further compared with associations between metabolic markers and CVD risk.Results:Egg consumption was associated with 24 out of 225 markers, including positive associations for apolipoprotein A1, acetate, mean HDL diameter, and lipid profiles of very large and large HDL, and inverse associations for total cholesterol and cholesterol esters in small VLDL. Among these 24 markers, 14 were associated with CVD risk. In general, the associations of egg consumption with metabolic markers and of these markers with CVD risk showed opposite patterns.Conclusions:In the Chinese population, egg consumption is associated with several metabolic markers, which may partially explain the protective effect of moderate egg consumption on CVD.Funding:This work was supported by the National Natural Science Foundation of China (81973125, 81941018, 91846303, 91843302).

Managing the Grey-headed Flying-fox as a threatened species in New South Wales two decades on: threats and conservation issues
Authors: Mo Matthew , Coutts-McClelland Kylie , Wilson Vanessa , Haering Ron , Oliver Lorraine , Bell Linda , Lunney Daniel 
Published: May 2022

ABSTRACT
The Grey-headed Flying-fox Pteropus poliocephalus was listed as a vulnerable species by both the New South Wales (NSW) and Australian Governments in 2001. The NSW Government has since collaborated with other organisations and stakeholders on projects and initiatives for flying-fox conservation and population monitoring. While contentious issues for horticulturalists and communities are detailed in a companion paper, this paper examines a number of persistent threats and conservation issues, such as habitat destruction and food shortages, anthropogenic injuries and extreme heat events. While there have been several independent efforts to conserve flying-fox habitat leading up to the recent commencement of a state-wide funding program for flying-fox habitat restoration, the continual loss of foraging habitat to urban development occurring at a greater scale is a conundrum. Flying-foxes suffering from injuries with anthropogenic causes are primarily addressed by wildlife carers rescuing and rehabilitating them. Additionally, preventative actions, such as promotion of wildlife-friendly netting, are implemented by different organisations to reduce injuries. There is also work being done by government agencies, land managers, scientists and wildlife carers to improve heat stress management, including moving towards a more coordinated and collaborative approach for responding to extreme heat events and undertaking scientific research. The diversity of threats affecting the Grey-headed Flying-fox means that the species’ conservation is beyond the capacity of any one organisation and relies on the collaborative efforts of a broad range of stakeholders across the entire species’ range.

Published: May 2022

Indiscriminate dumping of municipal and industrial wastes in our environment has increased human exposure to hazardous substances which is detrimental to their health. In this research, radionuclide transfer factor was ascertained from crops planted near major dump sites in Rivers State. Samples of food crops and soil near the dumpsites were collected for gamma spectroscopy. The average activity concentration of 40K, 238U and 232Th in soil are 115.87 \(\pm\) 17.01 Bqkg-1, 31.54 \(\pm\) 7.13 Bqkg-1 and 18.77 \(\pm\) 6.02 Bqkg-1. While in crop are 403.46 \(\pm\) 13.06 Bqkg-1, 9.54 \(\pm\) 4.02 and 22.245.11. In soil, all the radionuclide values were all within the world average value and in crop, the values were also within the world average value except for 40K that was more prevalent in crop and exceeds the world average value of 400Bqkg-1. The activity concentration of radionuclides 40K, 238U and 232Th for transfer factor are 8.187667Bqkg-1, 0.231667Bqkg-1 and 2.144333Bqkg-1 respectively with potassium having the highest mean transfer factor which may be due to its higher accumulation in crop. Based on this finding, cassava products cultivated in dumpsites are not radiologically free and safe for human consumption.
H2O2 Exfoliation of TiO2 for Enhanced Hydrogen Production from Photocatalytic Reforming of Methanol
Authors: Razak Syaahidah Abdul , Bahruji Hasliza , Mahadi Abdul Hanif , Yun Hong Wan 
Published: May 2022

Hydrogen is considered a future energy carrier for clean and sustainable technology. Photocatalytic reforming of methanol produced hydrogen using water and energy from sunlight. This study reported enhanced activity of TiO2 without metal co-catalyst for hydrogen production following H2O2 exfoliation. TiO2 was transformed into peroxo-titania species on the outer layer of the particles, resulting in surface exfoliation. The exfoliation reduced TiO2 crystallite sizes enhanced the surface hydroxyl group and reduced the band gap to 3.0 eV. Hydrogen production from methanol-water mixtures on the TiO2 after four consecutive exfoliations was measured at 300 µmol, significantly higher than the fresh TiO2 (50 µmol). H2O2 exfoliated TiO2 reduced the pathway for charge migration to the surface. A high concentration of surface hydroxyl group trapped the charge carriers for efficient hydrogen production.

Published: May 2022

AbstractRed and green InP quantum dots (QDs) already have been demonstrated with excellent luminescence performance closing the gap with CdSe‐based QDs. However, the performance of blue InP QDs still lags behind that of red and green QDs. For blue InP QDs synthesized by aminophosphine and zinc iodide, the inherent I– possesses weak passivation ability. By introducing Br– with a smaller ion radius and larger binding energy, the quantum yield of blue InP QDs is increased from 54% to 93%, which is the highest value reported so far. Meanwhile, the long‐chain 1‐dodecanethiol is replaced by the short‐chain 1‐octanethiol through ligand exchange to increase the carrier injection efficiency. The blue quantum dot light‐emitting diodes (QLEDs) made of these QDs showed an external quantum efficiency of 2.6%, which is notably the highest blue InP QLED reported so far.
Do farmers need to be paid to grow milkweed for monarchs or will they volunteer if it is easy enough?
Authors: Thakur Tiesta , Hurley Terrance 
Published: May 2022

AbstractA decline in the monarch butterfly population led the U.S. Fish and Wildlife Service to acknowledge monarchs should be listed under the 1973 Endangered Species Act. This research evaluates farmer interest in restoring monarch habitat on their non‐cropped acres to help circumvent such a listing. Results suggest that efforts to promote habitat restoration on non‐cropped acres should focus on voluntary participation and make programs as easy as possible through design and technical assistance. The results also suggest that even a successful program can only provide a small fraction of the habitat needed to meet current restoration goals.
Substituent effects of tertiary phosphines on the structures and electrochemical performances of azadithiolato‐bridged diiron model complexes of [FeFe]‐hydrogenases
Authors: Liu Xu‐Feng , Ma Zhong‐Yi , Jin Bo , Wang Dong , Zhao Pei‐Hua 
Published: May 2022

In this work, a new series of azadithiolato‐bridged diiron complexes [Fe2(μ‐adtNOH)(CO)5{P(C6H4R)3}] (adtNOH = (SCH2)2N(C6H4CH2CH2OH‐p) and R = Cl‐p, 1; Me‐m, 2; OMe‐p, 3 supported by tertiary phosphines, which may be considered as the active site models of [FeFe]‐hydrogenases, has been prepared in 73–81% yields by the Me3NO‐assisted decarbonylating reactions of all‐CO precursor [Fe2(μ‐adtNOH)(CO)6] (A) with several tertiary phosphines [(P(C6H4R)3] in MeCN at room temperature. All the new complexes 1–3 are fully characterized by elemental analysis, spectroscopic techniques (Fourier transform‐infrared spectroscopy [FT‐IR] and nuclear magnetic resonance [NMR]), and especially for 1 and 3 by X‐ray crystallography. The IR and 31P{1H} NMR spectroscopic analyses have shown that the electron density of diiron center in 1–3 may be adjusted by the introduction of the different substituents (R) of the P(C6H4R)3 ligands into the [2Fe2S] cluster. The X‐ray crystallographic investigation has displayed that the typical Fe‐Fe, Fe‐P, and Fe‐C distances of 1–3 are significantly influenced by the electronic effects of the P(C6H4R)3 phosphines coordinated apically to one Fe atom, whereas their Papical‐Fe‐Fe and Capical‐Fe‐Fe angles are mainly controlled by the steric interaction between the phosphine ligands and the dithiolate bridges. Further, the electrochemical performances of 1–3 are studied and compared in the absence or presence of acetic acid (HOAc) as proton source by using cyclic voltammetry, suggesting that they are active for the electrocatalytic proton reduction to hydrogen (H2).
Enzyme‐assisted extraction of chicken skin protein hydrolysates and fat: Degree of hydrolysis affects the physicochemical and functional properties
Authors: Safar Razavizadeh Rahimeh , Farmani Jamshid , Motamedzadegan Ali 
Published: May 2022

AbstractEnzyme‐assisted extraction (EAE) of oils/fats involves the disruption of the cell wall of source material using enzymes to facilitate the release of oil. When proteases are used as the enzyme, EAE ends in the extracted oil as well as the protein hydrolysates. Herein, the EAE (using a commercial protease, Alcalase) was exploited to obtain fat and protein hydrolysates from chicken skin. Degree of hydrolysis (DH, the percentage ratio of cleaved peptide bonds), which showed a logarithmic correlation with the reaction time, was found to affect the properties of the products. As the DH increased, the peptide chain length of protein hydrolysates decreased which was confirmed by SDS‐PAGE analysis. With the increase of DH, the emulsifying activity index, foaming capacity, and oil holding capacity of the hydrolysates decreased but the solubility and emulsion stability index increased (p < 0.05). The DPPH free radical scavenging activity of the hydrolysates increased with the DH up to DH = 39.62% but decreased thereafter (p < 0.05). EAE resulted in a rise in fat yield and the fat contained a higher amount of unsaponifiables and lower free fatty acids (FFA) content, as compared to the control treatment (No enzyme, 80°C, 2 h, p < 0.05). DH affected the fat yield and the unsaponifiables content of the fat, positively (p < 0.05). However, it did not affect the fat FFA content and iodine value (p > 0.05). Results obtained here showed DH can be used as an effective measure for controlling the physicochemical and functional properties of chicken skin protein hydrolysates and fat in the EAE process.
