THERAGNOSTICS OF SAMARIUM-153-EDTMP IN PATIENTS BEARING PROSTATE CANCER AND OSSEOUS SECONDARIES: PALLIATIVE BUT ALSO TUMOURICIDAL
Authors: Valsamaki Pipitsa N. , Papadatou Vasiliki , Tologkos Stylianos , Alexiadis Triantafyllos , F. Samelis Georgios , Lambropoulou Maria , Zissimopoulos Athanassios
Published: February 2022

BACKGROUND:
153 The radionuclide samarium-153 ( Sm) in a chelated compound with ethylene-diamine-tetramethylene phosphonate
(EDTMP) is mainly used as an alternative to palliative therapy of multifocal painful osseous metastases due to various primaries, especially
153 prostate, breast, lung cancer, and osteosarcoma. Considering novel aspects of chemical properties attributed to Sm, we aimed at evaluating the
153 outcomes of solitary versus repeated Sm-EDTMPor exclusive opiate therapy in patients with osseous secondaries from prostate cancer.
MATERIALS AND METHODS: In the present retrospective study, we included three groups of patients with hormone-refractory prostate
cancer (HRPC) and multiple painful osteoblastic or mixed secondaries conrmed by bone scintigraphy. Forty-three patients (Group A) received 2
153 consecutive intravenous (i.v.) administrations of Sm-EDTMP (37 MBq/kg of body weight each), twelve patients (Group B) received a solitary
153 i.v. dose Sm-EDTMP and 12 patients (Group C) used solely opiates due to exclusion criteria regarding radiometabolic therapy.
RESULTS: 153 Pain palliation was reported by 90.7% of group Apatients after the second injection. The repeated dose of Sm-EDTMPimproved the
duration of pain response to 24±6 versus 8±2 weeks of the single dose treatment plan, without signicant myelotoxicity. Group C patients were
considered as non-responders owing to increased pain score and consumption of analgesics.
CONCLUSION: 153 Arepeated-dose Sm-EDTMPtreatment scheme consistently provides enhanced pain alleviation, thereby preserving quality of
153 life in patients with skeletal metastases from HRPC. Interestingly, radiometabolic therapy with Sm-EDTMP effectuates tumouricidal
implications, thus upgrading a palliative agent to a disease theragnostics-targeted modier, with anticipated survival benet.
DO MEDICAL RESEARCH PRESENTATIONS HAVE A ROLE TO PLAY IN SHARPENING THE CAMPUS LEARNING

Research presentations and meetings are supposed to fulll a critical role in the ongoing education of health science students, lecturers, technicians,
nurses, and other health care educators. There are many functions which these conferences meet in addition to imparting education: sharpening the
skills, ability to interact with peers, trying new equipment, evolving novel and locally relevant ideas, developing consensus in contentious areas all
leading to improvement in medical education, health-care delivery, and patient outcomes. However, at the moment, the research presentations by
health science students are too little and not very effective in delivering the purported benet. Further, there is need to reconcile the entanglement of

Bitcoin's Growing Pains: Intermediation and the Need for an Effective Loss Allocation Mechanism
Authors: Kang Andrew
Published: February 2022

This paper examines a phenomenon largely overlooked in existing literature: as Bitcoin matures into a mainstream consumer payments system with the rise of intermediation and hosted wallet services, it is slowly transforming from a purely decentralized peer-to-peer currency into something that (ironically) more closely resembles the bank-intermediated payment systems of the past. This paper explains how this transformation creates complicated issues of loss allocation not anticipated by Bitcoin’s founder. Further, it argues for the need of an effective legal mechanism to efficiently and fairly allocate losses between intermediaries and users. The first section of this paper will explain how Bitcoin transactions work when users manage their own personal wallets, describing both the transaction mechanics and risks of loss. Then, it will explain how hosted wallet services have changed these mechanics and risks, as well as why a set of loss allocation rules is necessary. Finally, the paper will recommend a set of loss allocation rules based on the policy rationales that drive rules under other existing payment systems law.
Finance and Growth: The Legal and Regulatory Implications of the Role of the Public Equity Market in the United States
Authors: Mitchell Ezra
Published: February 2022

The important study of the relationship between finance and economic growth has exploded over the past two decades. One of the most significant open questions is the role of the public equity market in stimulating growth and the channels it follows if it does. This paper examines that question from an economic, legal, and historical perspective, especially with regard to its regulatory and corporate governance implications. The US market is my focus.

In contrast to most studies, I follow both economic history and the actual flow of funds in addition to empirics and theory to conclude that the public equity market’s contribution to US economic growth is highly limited to the small but important contemporary role it plays in providing exit opportunities for entrepreneurs and venture capitalists. Nevertheless, there is a serious question as to the real economic growth benefit of easy exit. In particular, exit by merger may well be more macro-economically efficient than exit by IPO.

I further tentatively conclude that the modern behavior of the US public equity market may be damaging to the long-term sustainability of American corporate capitalism and to long-term social welfare – in particular the market’s significant role in increasing economic inequality. Thus an overall appraisal of the market’s benefits and costs in the broader context of economic growth and economic inequality is long overdue. Important questions for corporate governance, financial regulation, and the structure of market institutions are raised. Along the way, I will have reason to question the continuing viability of the Miller-Modigliani irrelevance theorem.

$H$-Chromatic Symmetric Functions
Authors: Eagles Nancy Mae , Foley Angèle M. , Huang Alice , Karangozishvili Elene , Yu Annan
Published: February 2022

We introduce $H$-chromatic symmetric functions, $X_{G}^{H}$, which use the $H$-coloring of a graph $G$ to define  a generalization of Stanley's chromatic symmetric functions. We say two graphs $G_1$ and $G_2$ are $H$-chromatically equivalent if $X_{G_1}^{H} = X_{G_2}^{H}$, and use this idea to study uniqueness results for $H$-chromatic symmetric functions, with a particular emphasis on the case $H$ is a complete bipartite graph. We also show that several of the classical bases of the space of symmetric functions, i.e. the monomial symmetric functions, power sum symmetric functions, and elementary symmetric functions, can be realized as $H$-chromatic symmetric functions. Moreover, we show that if $G$ and $H$ are particular types of multipartite complete graphs we can derive a set of $H$-chromatic symmetric functions that are a basis for $\Lambda^n$. We end with some conjectures and open problems.
On Pattern Avoidance in Matchings and Involutions
Authors: Fang Jonathan J. , Hamaker Zachary , Troyka Justin M.
Published: February 2022

We study the relationship between two notions of pattern avoidance for involutions in the symmetric group and their restriction to fixed-point-free involutions. The first is classical, while the second appears in the geometry of certain spherical varieties and generalizes the notion of pattern avoidance for perfect matchings studied by Jelínek. The first notion can always be expressed in terms of the second, and we give an effective algorithm to do so. We also give partial results characterizing the families of involutions where the converse holds. As a consequence, we prove two conjectures of McGovern characterizing (rational) smoothness of certain varieties. We also give new enumerative results, and conclude by proposing several lines of inquiry that extend our current work.
The Eigenvalues of Hyperoctahedral Descent Operators and Applications to Card-Shuffling
Authors: Pang C. Y. Amy
Published: February 2022

We extend an algebra of Mantaci and Reutenauer, acting on the free associative algebra, to a vector space of operators acting on all graded connected Hopf algebras. These operators are convolution products of certain involutions, which we view as hyperoctahedral variants of Patras's descent operators. We obtain the eigenvalues and multiplicities of all our new operators, as well as a basis of eigenvectors for a subclass akin to Adams operations. We outline how to apply this eigendata to study Markov chains, and examine in detail the case of card-shuffles with flips or rotations.
Tiling Enumeration of Hexagons with Off-Central Holes
Authors: Lai Tri
Published: February 2022

This paper is the sequel of the author's previous paper about tiling enumerations of the cored versions of a doubly-intruded hexagon (Electron. J. Combin. 2020), in which we generalized Ciucu's work about $F$-cored hexagons (Adv. Math. 2017). This paper provides an extensive list of thirty tiling enumerations of hexagons with three collinear chains of triangular holes.  Besides two chains of holes attaching to the boundary of the hexagon, we remove one more chain of triangles that is slightly off the center of the hexagon. Two of our enumerations imply two conjectures posed by Ciucu, Eisenkolbl, Krattenthaler, and Zare (J. Combin. Theory Ser. A 2001).

Pekanbaru City is the capital of Riau Province which has a majority of the population of Malay ethnicity. In maintaining its cultural characteristics, in the city of Pekanbaru there are many contemporary buildings that have the implementation of Malay characteristics on the facades of the buildings, which one is the object of this research, government offices in Tenayan Raya and Balai Payung Sekaki buildings, because the culture in an area is not only can be seen on thel Traditional House building, but other buildings must also be able to reflect regional characteristics such as a regional government office building which is one of the markers of an area. However, the application of Malay architecture must be done as well as possible so that there is no mistake because it can change the meaning contained in each characteristic feature of Malay architecture, meybe on roof components, ornaments or others. Misunderstanding or ignorance of a role in building also has a fatal impact on these formations. Although in plain view, these forms seem beautiful to feel, but philosophically and the meaning can be wrong. This research will be conducted with a descriptive approach to interpret an existing condition with a related theoretical basis to see the implementation of Malay architecture on the facades of contemporary buildings in Pekanbaru City. The entire implementation of Malay in buildings in the Tenayan Office area can be categorized as quite good in terms of authenticity because all the roofs and ornamental designs have the same motifs as the original motifs in traditional Malay buildings. The technique of applying ornament to the object of this research also varies, some are done by means of Stilation, Distortion or Repetition. However, he could not find any ornamental motifs that were applied using Decoration techniques.

γδ T cell costimulatory ligands in antitumor immunity
Authors: McGraw Joseph M. , Witherden Deborah A.
Published: February 2022

Antitumor immunity relies on the ability of T cells to recognize and kill tumor targets. γδ T cells are a specialized subset of T cells that predominantly localizes to non-lymphoid tissue such as the skin, gut, and lung where they are actively involved in tumor immunosurveillance. γδ T cells respond to self-stress ligands that are increased on many tumor cells, and these interactions provide costimulatory signals that promote their activation and cytotoxicity. This review will cover costimulatory molecules that are known to be critical for the function of γδ T cells with a specific focus on mouse dendritic epidermal T cells (DETC). DETC are a prototypic tissue-resident γδ T cell population with known roles in antitumor immunity and are therefore useful for identifying mechanisms that may control activation of other γδ T cell subsets within non-lymphoid tissues. This review concludes with a brief discussion on how γδ T cell costimulatory molecules can be targeted for improved cancer immunotherapy.

Objetivo do estudo: Analisar se o direito ao saneamento básico era, de fato, assegurado para a população de Porto Seguro assim como é prezado na Constituição da República Federativa do Brasil, a partir das percepções da população. Além disso, buscamos entrecruzar como referencial teórico os pensamentos de Patrícia Borja e a realidade do saneamento vivenciada pelo público em Porto Seguro. Metodologia: O método utilizado foi o quantitativo. Assim sendo, foram aplicados questionários para a população em Unidades Básicas de Saúde de três diferentes bairros da cidade. Em seguida foi feita uma análise quantitativa dos resultados. Relevância: O tema está conexo com a intrínseca relação entre a efetiva prestação dos serviços de saneamento básico e a qualidade de vida da população. Principais resultados: Ficou evidenciada a enorme insatisfação popular com os serviços de saneamento básico ofertados na cidade de Porto Seguro. Apesar das legislações assegurarem a plena eficácia do serviço, na prática não é o que a população percebe, já que conforme os resultados obtidos 83% dos entrevistados discordavam da plena eficácia do serviço. Outro fator analisado foi a percepção de que a maioria não sabia o englobava os serviços de saneamento básico. Contribuições teóricas: O presente trabalho traz como contribuição um implemento na relevância atribuída aos direitos sociais hodiernamente, mostrando que os mesmos se analisados sob um viés holístico influenciam diretamente na qualidade de vida da população e concomitantemente na manutenção de um meio ambiente saudável e equilibrado.
Delivering Culturally Competent and Equitable Police Services Via Social Media: Assessing Two Way Dialogue between Police Agencies and Vulnerable Citizens
Authors: Patrick Barbara , Rollins Aaron
Published: February 2022

Social media is quickly becoming one of the most important media outlets for police departments; it provides them with the opportunity to engage in two-way dialogue with citizens. This direct line of communication can help build trust and legitimacy among racial minorities and other vulnerable groups with whom relationships are strained. However, little is known about the presence of cultural competency, legitimacy and social equity content in these exchanges. This research assesses these issues through an examination of Facebook interactive exchanges between citizens and police departments. The results reveal two key findings. First, vulnerable citizens’ comments and questions are more likely to raise concerns about agencies commitment to delivering culturally competent and socially equitable services. Next, agencies ignore, or rarely respond to, inquiries raising cultural and equity concerns. These findings highlight the need for future exploration of the use of social media accounts by police departments.
Substructure at High Speed. I. Inferring the Escape Velocity in the Presence of Kinematic Substructure
Authors: Necib Lina , Lin Tongyan
Published: February 2022

The local escape velocity provides valuable inputs to the mass profile of the galaxy, and requires understanding the tail of the stellar speed distribution. Following Leonard & Tremaine, various works have since modeled the tail of the stellar speed distribution as

∝

(

v

esc

−
v
)

k

, where v
esc is the escape velocity, and k is the slope of the distribution. In such studies, however, these two parameters were found to be largely degenerate and often a narrow prior is imposed on k in order to constrain v
esc. Furthermore, the validity of the power-law form can breakdown in the presence of multiple kinematic substructures or other mis-modeled features in the data. In this paper, we introduce a strategy that for the first time takes into account the presence of kinematic substructure. We model the tail of the velocity distribution as a sum of multiple power laws as a way of introducing a more flexible fitting framework. Using mock data and data from FIRE simulations of Milky Way-like galaxies, we show the robustness of this method in the presence of kinematic structure that is similar to the recently discovered Gaia Sausage. In a companion paper, we present the new measurement of the escape velocity and subsequently the mass of the Milky Way using Gaia eDR3 data.
The Complex Infrared Dust Continuum Emission of NGC 1068: Ground-based N- and Q-band Spectroscopy and New Radiative Transfer Models

Published: February 2022

Thanks to ground-based infrared and submillimeter observations the study of the dusty torus of nearby active galactic nuclei has greatly advanced in the last years. With the aim of further investigating the nuclear mid-infrared emission of the archetypal Seyfert 2 galaxy NGC 1068, here we present a fitting to the N- and Q-band Michelle/Gemini spectra. We initially test several available spectral energy distribution (SED) libraries, including smooth, clumpy and two-phase torus models, and a clumpy disk+wind model. We find that the spectra of NGC 1068 cannot be reproduced with any of these models. Although, the smooth torus models describe the spectra of NGC 1068 if we allow variation of some model parameters among the two spectral bands. Motivated by this result, we produced new SEDs using the radiative transfer code SKIRT. We use two concentric tori that allow us to test a more complex geometry. We test different values for the inner and outer radii, half-opening angle, radial, and polar exponent of the power-law density profile, opacity, and viewing angle. Furthermore, we also test the dust grains’ size and different optical and calorimetric properties of silicate grains. The best-fitting model consists of two concentric components with outer radii of 1.8 and 28 pc, respectively. We find that the size and the optical and calorimetric properties of graphite and silicate grains in the dust structure are key to reproducing the spectra of NGC 1068. A maximum grain size of 1 μm leads to a significant improvement in the fit. We conclude that the dust in NGC 1068 reaches different scales, where the highest contribution to the mid-infrared is given by a central and compact component. A less dense and extended component is present, which can be either part of the same torus (conforming a flared disk) or can represent the emission of a polar dust component, as already suggested from interferometric observations.
A Nuclear Equation of State Inferred from Stellar r-process Abundances
Authors: Holmbeck Erika M. , O’Shaughnessy Richard , Delfavero Vera , Belczynski Krzysztof
Published: February 2022

Binary neutron star mergers (NSMs) have been confirmed as one source of the heaviest observable elements made by the rapid neutron-capture (r-) process. However, modeling NSM outflows—from the total ejecta masses to their elemental yields—depends on the unknown nuclear equation of state (EOS) that governs neutron star structure. In this work, we derive a phenomenological EOS by assuming that NSMs are the dominant sources of the heavy element material in metal-poor stars with r-process abundance patterns. We start with a population synthesis model to obtain a population of merging neutron star binaries and calculate their EOS-dependent elemental yields. Under the assumption that these mergers were responsible for the majority of r-process elements in the metal-poor stars, we find parameters representing the EOS for which the theoretical NSM yields reproduce the derived abundances from observations of metal-poor stars. For our proof-of-concept assumptions, we find an EOS that is slightly softer than, but still in agreement with, current constraints, e.g., by the Neutron Star Interior Composition Explorer, with R
1.4 = 12.25 ± 0.03 km and M
TOV = 2.17 ± 0.03 M

StrayCats, the catalog of NuSTAR stray light observations, contains data from bright X-ray sources that fall within crowded source regions. These observations offer unique additional data with which to monitor sources such as X-ray binaries that show variable timing behavior. In this work, we present a timing analysis of stray light data of the high-mass X-ray binary SMC X-1, the first scientific analysis of a single source from the StrayCats project. We describe the process of screening stray light data for scientific analysis, verify the orbital ephemeris, and create both time- and energy-resolved pulse profiles. We find that the orbital ephemeris of SMC X-1 is unchanged and confirm a long-term spin-up rate of

Radialization of Satellite Orbits in Galaxy Mergers
Authors: Vasiliev Eugene , Belokurov Vasily , Evans N. Wyn
Published: February 2022

We consider the orbital evolution of satellites in galaxy mergers, focusing on the evolution of eccentricity. Using a large suite of N-body simulations, we study the phenomenon of satellite orbital radialization—a profound increase in the eccentricity of its orbit as it decays under dynamical friction. While radialization is detected in a variety of different setups, it is most efficient in cases of high satellite mass, not very steep host density profiles, and high initial eccentricity. To understand the origin of this phenomenon, we run additional simulations with various physical factors selectively turned off: satellite mass loss, reflex motion and distortion of the host, etc. We find that all these factors are important for radialization because it does not occur for point-mass satellites or when the host potential is replaced with an unperturbed initial profile. The analysis of forces and torques acting on both galaxies confirms the major role of self-gravity of both host and satellite in the reduction of orbital angular momentum. The classical Chandrasekhar dynamical friction formula, which accounts only for the forces between the host and the satellite, but not for internal distortions of both galaxies, does not match the evolution of eccentricity observed in N-body simulations.
Profiles of Children with Lower Extremity Fracture at Saiful Anwar Malang Regional General Hospital from January 2016 to August 2020

Published: February 2022

Musculoskeletal injuries in children are a common cause of 25% of children hospitalization. Previous research stated that five pediatric fractures had significant long-term consequences such as disability and activity restriction. In Indonesia, epidemiology studies have discussed the incidence of fracture in general sites, but only a few reported lower limb fractures. The authors expect this research to be used for lower extremities fractures in children’s epidemiologic descriptions. Between January 2016 until September 2020, we included 247 children under 18 years old based on inclusion criteria. The prevalence and fractures were reviewed for detail, such as sex, age, mechanism of injury, location of the fracture, and treatment. Data were analyzed using SPSS version 26. Most common injuries occur at 13-18 years old with 164 children (66.4%). Most of them were caused by traffic accidents, 210 cases (85.0%). Consequently, femur fractures are the most common fractures due to traffic accidents 53.8% (p<0.005). From common fracture sites in this study, plating is the common to use procedure than the others (52.3%). Therefore, we can conclude that MVA were the most common injury in children, and especially for fracture femur relevant with increasing age and plating methods is common to use method for this fracture
Low-dose Indonesian Aloe vera Increases Viability and Migration of the Fibroblast: An In Vitro Study
Authors: Rizqi Januar , Fitriawan Akbar Satria
Published: February 2022

BACKGROUND: Important stages in wound healing involve homeostasis, inflammation, proliferation, and remodeling phases. Fibroblasts are essential factors in the healing pathway through the process of cell proliferation and migration. Aloe vera contains various active compounds used for anti-inflammatory, antimicrobial, immunomodulatory, anticancer, and wound healing.

AIM: This study aimed to evaluate the effect of A. vera on the viability and migration of fibroblast cells.

MATERIALS AND METHODS: Fibroblasts were cultured in a monolayer with Dulbecco’s Modified Eagle Medium containing 10% fetal bovine serum, 1% pinstripe, and 0.5% fungizone. We use fresh A. vera leaves extracted with 95% ethanol. Cell viability will be evaluated using the MTT test and microscopic evaluation. Cell migration was tested using an in vitro wound scratch assay and analyzed with ImageJ software.

RESULTS: A. vera stimulated cell viability compared to control (p < 0.05). Administration of A. vera does not change shape and is not toxic to fibroblasts. A. vera stimulated cell migration at doses of 250, 125, 50, and 5 μg/mL compared to control after 24 h of intervention. At 48 h incubation, migration doses of 250, 50, and 5 μg/mL were higher than control (p < 0.05).

CONCLUSIONS: A. vera extract may effectively wound healing by increasing viability and migration of fibroblast cells.

The dataset we present consists of an inventory compiling all records and knowledge about Staphylinidae (Insecta, Coleoptera) in the Azores and is part of a long-term monitoring performed between 1990 and 2015 in different habitat types of eight islands of the Azores Archipelago. Most samples come from the BALA project (Biodiversity of Arthropods from the Laurisilva of Azores) that sampled native forests in the Azores. Additional sampled habitats include exotic forests, intensive and semi-natural pasturelands, orchards, caves and lava flows. Most of the records (about 96.7%) were collected in standardised sampling campaigns, which included pitfall traps and beating transect protocols. Non-standardised records are based on hand-collecting and sifting, as well as cave, colour and malaise traps.

We provide a long-term inventory of Staphylinidae (Insecta, Coleoptera) collected in the course of several standardised sampling campaigns and recorded with non-standardised methods. We collected a total of 10744 specimens belonging to 69 identified species of Staphylinidae, which represents 51% of the species known from the Azores Archipelago. Four endemic species were sampled, representing 40% of the known Azorean endemic species. From this dataset, seven species are new for the Azores:Aleochara funebrisWollaston, 1864;Amischa forcipataMulsant & Rey, 1873;Bledius unicornis(Germar, 1825);Carpelimus troglodytes(Erichson, 1840);Cypha seminulum(Erichson, 1839);Paraphloeostiba gayndahensis(MacLeay, 1871);Tachyporus caucasicusKolenati, 1846. We also registered a total of 66 new island records for eight Azorean islands. This contribution continues a series of publications on the distribution and abundance of Azorean arthropods. We also provide an updated list of Azorean rove-beetles (Staphylinidae) that now includes 136 species, ten of them considered Azorean endemics.
Relations hommes-femmes en milieu rural : une communauté amish dans les années 1930
Authors: Jellison Katherine
Published: February 2022

L’étude des amish du Vieil Ordre du comté de Lancaster (Pennsylvanie) pendant les années 1930 met nettement en évidence les caractéristiques et les pratiques qui rendirent possible une agriculture familiale prospère dans un contexte de crise économique. Rejetant le modèle d’une agriculture mécanisée et à forte intensité capitalistique au profit d’une agriculture traditionnelle à forte intensité de main-d’œuvre, les amish restèrent fidèles à une organisation du travail qui exigeait de transgresser la stricte division des rôles entre les sexes. Si les hommes se considéraient prioritairement comme des cultivateurs et les femmes comme des ménagères, la bonne santé de leurs exploitations nécessitait en réalité un degré élevé de coopération et de travail en commun. S’appuyant sur des données issues d’enquêtes gouvernementales sur les comportements d’achat, l’auteure examine de quelle manière la répartition sexuée des rôles au sein de la population amish du comté de Lancaster permit à celle-ci de surmonter la crise avec plus de bonheur que d’autres communautés paysannes.
Peut-on se passer de l’hôpital psychiatrique ?
Authors: Paoli Benjamin
Published: February 2022

Nous interrogeons la place de l’hospitalisation temps-plein, héritière du modèle asilaire, dans l’organisation du soin psychiatrique actuel. La politique sectorielle française semble trouver sa justification dans le développement d’alternatives à l’hospitalisation. Elles seraient des critères de qualité objectivables de la prise en charge psychiatrique. Nous interrogeons cliniquement ce modèle et proposons l’exemple d’une unité d’hospitalisation intégrée au dispositif de soin sectoriel. Face au délitement du système de soins psychiatriques en France, nous nous inquiétons du manque de moyen plutôt que du modèle d’organisation des soins.
Characterization and Health-Related Quality of Life in Older Adults With Disabilities According to Timing of Disability Onset
Authors: Yang Eunjin , Kim Hee Jung , Lee Kyoung-eun
Published: February 2022

The current study examined characteristics of early-onset and late-onset disability in older adults and identified predictors of health-related quality of life (HRQoL). This is a secondary data analysis of the 2017 national survey in South Korea. Participants were 4,014 older adults with disabilities, who were divided into an early-onset group (
n
= 2,229) and late-onset group (
n
= 1,785). Data were analyzed using complex sample analyses. Difficulties during outdoor activity and transportation use, self-rated health, and stress were common predictors in both groups. Comorbidity was a significant predictor only in the early-onset group. Use of information technology devices, household income, and perceived social discrimination were significant predictors in the late-onset group. Characteristics and predictors of HRQoL were different between groups, despite sharing common characteristics. It is necessary to improve support systems and health care services for older adults with disabilities. [

Published: February 2022

Preventing postoperative complications is crucial for patients, surgeons, and health care facilities. We developed a risk stratification scoring system to optimize postoperative outcomes for patients undergoing foot and ankle surgery. A total of 35,580 patients who underwent foot and ankle procedures from 2005 to 2017 were identified as part of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). To assess the risk of a postoperative complication, we identified several independent risk factors associated with 30-day postoperative complications, then proceeded to develop a point-based risk scoring system. To validate our scoring system, we used it on a cohort of patients from the database who underwent foot and ankle surgery. Risk factors that correlated with postoperative complications included tobacco abuse, age (≥65 years), diabetes mellitus, hypertension, elevated creatinine level (≥1.3 mg/dL), hypoalbuminemia (<3.5 g/dL), chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), hyponatremia (<135 mEq/L), and anemia (hematocrit value, men <42%; women <38%). Point scores for each factor were: anemia, +10; hypoalbuminemia, +9; elevated creatinine level, +6; CHF, +4; diabetes mellitus, +3; hyponatremia, +3; COPD, +2; hypertension, +2; age, +1; and tobacco abuse, +1. For the validation cohort, we stratified patients according to risk as low (0–20 points), medium (21–30 points), and high (≥31 points) risk. In terms of having a postoperative complication, compared with low-risk patients, patients who were at medium risk had an odds ratio of 4.7 (95% CI, 2.8–7.9) and those at high risk had an odds ratio of 8.3 (95% CI, 4.8–14.5).

Orthopedics and US Politics: Trends in Political Donations by Orthopedic Surgeons
Authors: Jarvis Tyler , Morris Bryn E. , Rosenow Christian , Ahmadian David , Rulney Jarrod , Noland Shelley S.
Published: February 2022

The political climate surrounding health care policy in the United States has become increasingly controversial over the past two decades. Policies influencing the provision and administration of health care have provoked more political activism among physician stakeholders. Herein we describe the trends in political donations made by US orthopedic surgeons from 2003 to 2020. Political donation data from 2003 to 2020 were obtained from the Federal Election Commission website. Contributions were filtered by occupation matching either “orthopedic surgeon” or “orthopaedic surgeon.” Individual contributions were assigned to a beneficiary committee associated with a political party and used to classify donations as Independent, Republican, or Democratic. A total of 71,492 donations amounting to $30,930,242 were made by orthopedic surgeons between 2003 and 2020. The number of donations increased from 1368 in 2003 to 14,961 in 2020, with Independent committees averaging 68.4% of donations over the 18-year period. From 2003 to 2020, monies donated to Independent committees decreased from 71% to 34%, Republican donations increased from 23% to 55%, and Democratic donations increased from 6% to 11%. When stratified by state, orthopedic surgeon contributions favored Independent committees. There has been an increase in political involvement among US orthopedic surgeons in the past 18 years. Contributions to Independent committees were the most common; however, most donations were allocated to the American Academy of Orthopaedic Surgeons Independent political action committee, which has traditionally supported Republican candidates. Contributions became partisan in 2020 in favor of Republican committees. [
