Scope of Practice and Location of 3- Versus 4-Year Family Medicine Residency Graduates
Authors: Lefevre Nicholas M. , Young Richard A. , Li David M. , Casey Dan
Published: October 2022

Background and Objectives: The John Peter Smith (JPS) Family Medicine Residency Program participated in two national experiments: Preparing the Personal Physician for Practice (P4, 2007-2012) and the Length of Training Pilot, which began in 2013. In these experiments, JPS created optional integrated 4-year areas of emphasis (AOE). The objective of this study was to examine the career outcomes of JPS graduates differentiated by those who completed a 4-year AOE, versus traditional fourth-year fellowship, vs 3-year only.
Methods: We surveyed each graduate who started residency from 2007-2016 on their scope of practice. We also searched each graduate via Google to identify each of their practice sites and ascertain their status as a Health Professional Shortage Area (HPSA) or Medically Underserved Area for primary care (MUA-P).
Results: Of the 220 residents who entered the program as interns, 70 completed an integrated AOE (31.8%), 54 completed 3 years of training with a traditional fourth-year fellowship (24.5%, 40 at JPS, 14 at another location), and 93 completed only 3 years of training (42.3%). The overall percentage of JPS graduates who work in the United States (n=201) in HPSAs or MUA-Ps is similar to national numbers (45.3% vs 43.5% for HPSAs, 35.3% vs 33.3% for MUA-Ps). Graduates of a JPS integrated AOE track were more likely to work in a HPSA or MUA-P than other graduates (81.4% vs 38.5% traditional fellowship vs 45.6% 3-year only, P<.001; US practice sites only). Graduates of sports medicine fellowships were particularly less likely to work in HPSAs/MUA-Ps than other graduates (26.1%). Graduates of integrated AOEs provided much broader scopes of cognitive and procedural services than fellowship or 3-year graduates.
Conclusions: In JPS graduates, 4 years of training with an integrated AOE had a large association with serving vulnerable populations, and providing broader cognitive and procedural services.

Background and Objectives: Patients are best served by a health care workforce that reflects the diversity of their community. Increasing diversity of family medicine requires a long-term effort to recruit more medical students from underrepresented in medicine (URiM, defined as people of Black/African American, Hispanic/Latino, Native American or Pacific Islander heritage) backgrounds into family medicine residencies. This paper examines factors that influence URiM medical students to choose family medicine residencies.
Methods: Data were collected via a Council of Academic Family Medicine Educational Research Alliance (CERA) survey of family medicine clerkship directors. Correlations examined associations between the percent URiM faculty, percent URiM preceptors, percent clerkship cases addressing health equity, and the percent of URiM students choosing family medicine residencies. t tests determined associations between clerkship director race, preclinical electives on health equity, department faculty champion for diversity, and department diversity activities; and the percentage of URiM students choosing family medicine residencies.
Results: Survey response rate was 49%. Two factors had a positive relationship with the percentage of graduating students who were URiM choosing family medicine residencies: having a higher percentage of faculty who were URiM (r=0.33, P=.004) and having a higher percentage of preceptors who are URiM (rs=.386, P=.001). We found no such association for having cases addressing health equity, offering preclinical electives, departments with a faculty champion for diversity, clerkship director race, or a department’s diversity activities.
Conclusions: The presence of teaching faculty and community preceptors from URiM backgrounds is correlated with the rate at which students who are URiM choose family medicine. People, rather than activities, seem to influence the career choices of students from URiM backgrounds.

RESUMEN. Introducción: Las áreas protegidas privadas son un complemento valioso para los sistemas nacionales de áreas protegidas. La Reserva Sierra Zapote en Abangares, Costa Rica, establecida en 2000, protege 70 ha de bosque secundario avanzado, bosque secundario en regeneración y bosque ribereño primario. Se espera que favorezca a las comunidades faunísticas, como los mamíferos medianos y grandes, que se encuentran entre las especies más amenazadas por la pérdida y fragmentación del hábitat; actualmente existe la necesidad de evaluaciones faunísticas en Sierra Zapote. Objetivo: Evaluar la riqueza, abundancia relativa y patrones de actividad de estos mamíferos en la reserva. Métodos: De mayo de 2020 a julio de 2021, mantuvimos cinco cámaras trampa en sitios estratégicos y las programamos para que estuvieran activas las 24 horas del día (0,3 segundos entre disparos). Revisamos las cámaras cada 1-2 meses y también extrajimos datos de temperatura y fase lunar. Resultados: Obtuvimos 758 registros independientes de mamíferos con un esfuerzo de fototrampeo de 2 135 días. Las especies más abundantes fueron Nasua narica (índice de abundancia relativa RAI = 14,6, N= 312) y Didelphis marsupialis (RAI = 6,1, N= 130). Los menos abundantes fueron Herpailurus yagouaroundi y Procyon lotor (RAI = 0,05, N= 1). La mayoría de las especies son nocturnas y solo el saíno (Pecari tajacu), el pizote (Nasua narica) y la guatusa (Dasyprocta punctata) tienen actividad mayoritariamente diurna. El puma (Puma concolor) también habita en la reserva. Conclusión: Los patrones de actividad fueron los esperados; para el tamaño de la reserva, una riqueza de 19 especies es comparativamente alta. La presencia del puma, indicador de buena salud del ecosistema, deja entrever la importancia del proceso de restauración de la reserva.

Fechamento de escolas do campo no território de identidade baiano do Médio Rio de Contas
Authors: Silva Sandra Mara do Carmo , Santos Arlete Ramos dos
Published: October 2022

Este artigo apresenta o resultado da pesquisa sobre o fechamento de escolas do campo em municípios da Bahia, cujo recorte é Território de Identidade do Médio Rio de Contas — Ba, no marco temporal entre 2007 a 2019. Para o desenvolvimento da investigação foi realizado um levantamento de dados de dezesseis (16) municípios localizados no referido Território, desse total de municípios, foram selecionados aqueles com população maior que 15.000 habitantes. Os dados gerais foram coletados diretamente no site do INEP, e compreendeu os anos de 2007 a 2019. Dentre os municípios pesquisados, o de Jequié — Ba foi selecionado com base em três critérios: a) ter população maior que 15.000 habitantes b) ser de fácil acesso c) ter escolas no campo. A metodologia se assentou nas concepções teóricas do Método Materialismo Histórico Dialético, já os instrumentos para coleta de dados foram a análise documental e entrevistas semiestruturadas. Com o resultado da investigação constatamos que o fechamento de escolas do campo no município de Jequié — Ba é oriundo do processo de nucleação de escolas sob a justificativa do poder público municipal em conter gastos com transporte escolar, manutenção das escolas e contratação de professores. Assim, amplia-se, cada vez mais, o fechamento de escolas do campo pelos “detentores do poder”, ratificando, desse modo, as diretrizes neoliberais implementadas na educação.
Rapid Prototyping of Species Classifiers using Deep Learning: A Guide for Non-Experts
Authors: Chege Herman Njoroge
Published: October 2022

Deep learning algorithms are revolutionizing how hypothesis generation,
pattern recognition, and prediction occur in the sciences. In the life
sciences, particularly biology, and its subfields,  the use of deep
learning is slowly but steadily increasing. However, prototyping or
development of tools for practical applications remains in the domain of
experienced coders. Furthermore, many tools can be quite costly and
difficult to put together without expertise in Artificial intelligence
(AI) computing. We built a biological species classifier that leverages
existing open-source tools and libraries. We designed the corresponding
tutorial for users with basic skills in python and a small, but
well-curated image dataset. We included annotated code in form of a
Jupyter Notebook that can be adapted to any image dataset, ranging from
satellite images, animals to bacteria, or even data such as song or
echolocation recordings transformed into images. The prototype developer
is publicly available and can be adapted for citizen science as well as
other applications not envisioned in this paper.

We illustrate our approach with a case study of 219 images of 3 three
seastar species. We show that with minimal parameter tuning of the AI
pipeline we can create a classifier with 87% accuracy. We include
additional approaches to understand the misclassified images and to
curate the dataset to increase accuracy. The power of AI approaches is
becoming increasingly accessible. We can now readily build and prototype
species classifiers that can have a great impact on research that
requires species identification and other types of image analysis. Such
tools have implications for citizen science, biodiversity monitoring,
and a wide range of ecological applications.

Like a rolling stone: colonization and migration dynamics of the grey reef shark (Carcharhinus amblyrhynchos)

Published: October 2022

Designing appropriate management plans requires knowledge of both the
dispersal ability and what has shaped the current distribution of the
species under consideration. Here we investigated the evolutionary
history of the endangered grey reef shark (Carcharhinus
amblyrhynchos) across its range by sequencing thousands of RAD-seq loci
in 173 individuals in the Indo-Pacific (IP) . We first bring evidence of
the occurrence of a range expansion (RE) originating close to the
Indo-Australian Archipelago (IAA) where two stepping-stone waves (east
and westward) colonized almost the entire IP. Coalescent modeling
additionally highlighted a homogenous connectivity
(Nm~10 per generation) throughout the range, and
an isolation by distance model suggested the absence of barriers to
dispersal despite the affinity of C. amblyrhynchos to coral
reefs. This coincides with long-distance swims previously recorded,
suggesting that the strong genetic structure at the IP scale (FST
~ 0.56 between its ends) is the consequence of its broad
current distribution and organization in a large number of demes. Our
results strongly suggest that management plans for the grey reef shark
should be designed on a range-wide rather than a local scale due to its
continuous genetic structure. We further contrasted these results with
those obtained previously for the sympatric but strictly
lagoon-associated Carcharhinus melanopterus, known for its
restricted dispersal ability. C. melanopterus exhibits similar RE
dynamic, but is characterized by stronger genetic structure and a
non-homogeneous connectivity largely dependent on local coral reefs
availability. This sheds new light on shark evolution, emphasizing the
roles of IAA as source of biodiversity and of life history traits in
shaping the extent of genetic structure and diversity.
The infrequent large pelvi-perineal tumors as a surgical dilemma: en bloc resection and long-term results
Authors: Nassar Omaya
Published: October 2022

Objectives: To assess long-term results of surgical resections of the
sporadic extra-large pelvi-perineal soft tissue tumors. Design:
Retrospective series of patients referred to the National Cancer
Institute 2001-2022. Setting: Tertiary care cancer university hospital
in Egypt. Population: 13 patients (3 males) averaged age 57 years, had
large 29 cm (18-38) pelvi perineal tumors (10 to the paraanal
ischiorectal spaces & 3 vulval) plus upper intra-abdominal extensions
in 9 cases. Methods: The entire underwent combined open
abdomino-perineal approach to widely en masse resect tumors plus
infiltrated organ. No downsizing hormonal treatment was offered
preoperative. Main Outcome Measures: Disease free Survival, recurrence
characters and salvage Results: Extensive pelvic and perineal tumor
resection is tough and meticulous but straightforward with minor (CDC
grade I&II) early and delayed morbidity. Resection extends to
hysterectomy, vaginectomy and vascular resection. Histopathology plus
immunohistochemistry show 9-aggressive angiomyxoid tumors (AA),
2-fibromatosis and 2-neurofibromas. Margins of resection are all
adequate (R0) except for 2 (R1). After 50-months median follow up, 8/ 13
total series (61.5%) were surviving free of disease, 4/9 of AA (44%)
had local perineal and/or pelvic recurrences (13-27 m) and were amenable
to curative salvage resections; while, 1/2 of patients with fibromatosis
died of disseminated peritoneal relapses. No systemic metastases are
noticed. Conclusions: Extensive meticulous surgery with experienced
pelvic dissection and resection could offer alone long term cure even
after recurrences with minor morbidity in a good percent. Fertility
sparing resection is not oncologically safe because of the frequent
uterine and ovarian invasions.

Authors: Lakic Tanja , Sunjevic Milena , Ilic Aleksandra , Ilic-Sabo Jelena , Radosavkic Radosav
Published: October 2022

Introduction. Adenocarcinoma is the most common prostatic malignancy, where clinical management, the Gleason score, and recent updates in prostate cancer staging play critical roles. Mantle cell lymphoma (MCL) originates from the malignant transformation of B lymphocyte in the outer edge of the lymph node follicle, with pathognomonic over-expression of cyclin D1. We present a rare case of two simultaneous neoplasms occurring in the same patient. Case report. During the hospital preoperative examinations in a 68-year-old patient planned for radical prostatectomy, using multislice computed tomography, a tumor mass confined to the prostate, but also excessive lymph node enlargement, was revealed. Tissue specimens were analyzed after the hematoxylin and eosin staining was performed, as well as an immunohistochemical (IH) biomarker panel. Having performed a thorough histological examination, a diagnosis of prostatic adenocarcinoma was made, with a Gleason score 3 + 4 = 7 and Grade Group 2 of the International Society of Urological Pathology (ISUP). Microscopic analysis of lymph node involvement showed unexpected, diffuse proliferation of small lymphoid cells with irregular nuclei, wide mantle zone, and hyalinized blood vessels. After using IH staining for specific markers, another diagnosis was set, and it was non-Hodgkin MCL. Conclusion. A prostatic adenocarcinoma can rarely coexist with an undiagnosed lymphoproliferative disease, such as non-Hodgkin MCL in our case.

Intraretinal hyperreflective foci (HRF) are significant biomarkers for diabetic macular edema. However, HRF at the vitreoretinal interface (VRI) have not been examined in diabetic retinopathy (DR). A prospective observational clinical study with 162 consecutive eyes using OCT imaging showed significantly increased HRF at the VRI during DR progression (P<0.01), which was reversed by anti-VEGF therapy. F4/80+ macrophages increased significantly at the VRI in Kimba (vegfa+/+) or Akimba (Akita × Kimba) mice (both P<0.01), but not in diabetic Akita (Ins2+/-) mice, indicating macrophage activation was modulated by elevated VEGF rather than the diabetic milieu. Macrophage depletion significantly reduced HRF at the VRI (P<0.01). Furthermore, BrdU administration in Ccr2rfp/+Cx3cr1gfp/+ vegfa+/- mice identified a significant contribution of M2-like tissue-resident macrophages (TRMs) at the VRI. Ki-67- and CD11b-positive cells were observed in preretinal tissues of DR patients while exposure of vitreal macrophages to vitreous derived from PDR patients induced a significant proliferation response in vitro (P<0.01). Taken together, the evidence suggests that VEGF drives a local proliferation of vitreous resident macrophages (VRMs) at the VRI during DR. This phenomenon helps to explain the derivation and disease-relevance of the HRF lesions observed through OCT imaging in patients.

 
Study on andorite-series minerals from Meleg Hill, Velence Mts., Hungary
Authors: Papp Richárd Zoltán , Topa Boglárka Anna , Zajzon Norbert
Published: October 2022

During the last decades, different sulphosalts were observed in several samples that were investigated from the Meleg hill, Velence Mts. The investigated sample of this study was collected from the less studied north-eastern, stibnite-rich part of the hydrothermal breccia at the Meleg Hill. Based on the results of electron microprobe analysis, we found that the sample contained two sulphosalt minerals of the andorite series that have not been described from Hungary before. The andorite series is a subgroup of the lillianite homologous series. The individual minerals, andorite VI and roshchinite, within the andorite series were identified on the basis of their chemical composition and the andorite substitution percentage (L%). Andorite VI has Ag1.06Cu0.04Pb0.80Sb2.49Bi0.22As0.3S6 average chemical formula (normalized to 6 sulphur atoms) and L%=102.65–109.84, whereas roshchinite has Ag17.23Cu0.53Pb10.4Hg0.04Zn0.04Fe0.02Sb39.73Bi5.52As5.98S96 average chemical formula (normalized to 96 sulphur atoms) and  L% = 119.52–123.48. Our results suggest that the formerly used comparative ternary diagrams of the system (Ag2S + Cu2S)–(Sb2S3 + Bi2S3 + As2S3)–(PbS + HgS + FeS + ZnS + CdS) is not adequate to differentiate the andorite-series minerals from each other, due to the highly variable element substitution of Me+, Me2+ and Me3+ cations. The andorite substitution percentage (L%) and the andorite homologue order value (N) are always necessary to calculate to distinguish the mineral species.

Introduction

Une collaboration efficace et soutenue entre cliniciens et professionnels en santé publique peut améliorer la santé des individus et la santé de la population. Le concept de santé publique clinique favorise cette collaboration entre médecine clinique et santé publique et permet de relever des défis complexes en matière de santé.

Dans ce commentaire, nous décrivons le concept de santé publique clinique, les types de problèmes complexes qui nécessitent une collaboration entre les professionnels responsables de la santé des individus et ceux responsables de la santé de la population, de même que les obstacles à la santé publique clinique et les applications de la santé publique clinique qui ont émergé pendant la pandémie de COVID-19.

Argumentaire

Il existe une complémentarité entre la médecine clinique, qui est axée sur la santé des individus, et la santé publique, qui est axée sur la promotion et la protection de la santé des populations. Une collaboration entre ces deux disciplines est nécessaire pour résoudre les problèmes de santé complexes. Pour ce faire, toutefois, il convient de s’attaquer aux obstacles relatifs aux disciplines, ainsi qu’aux obstacles culturels et financiers qui empêchent une collaboration accrue et durable en la matière. Les succès récents, particulièrement durant la pandémie de COVID-19, constituent un modèle de collaboration de ce type entre cliniciens et praticiens en santé publique.

Conclusion

Une approche en matière de santé publique qui favorise une collaboration permanente entre cliniciens et professionnels en santé publique pour lutter contre des menaces sanitaires complexes aura plus d’impact que la somme de ses parties.

Malaria is the main cause of consultation and hospitalisation in health centres and the leading cause of morbidity and mortality in Côte d'Ivoire. To reduce malaria-related deaths, rapid diagnosis and treatment strategies should be adopted. The aim of this study was to determine the relationship between parasite density and selected haematological parameters in infected patients in cities located in southern Côte d'Ivoire. Blood samples were collected in Jacqueville and Tiassalé. The different haematological parameters were identified by an automated haematological analyser. The coefficient of determination (R2) was determined to show the proportion of variation in parasite density and each haematological parameter. A total of 69 patients were sampled. A negative correlation was observed between parasite density and haemoglobin in the general population, in Jacqueville and in Tiassalé. However, this correlation is significant in the general population (p1 = 0.046; Confidence Interval (CI= [-0.0047; -0.00010]) with a correlation intensity (r) different from zero (p2 = 0.05) and in Jacqueville (p1 = 0. 041; CI= [-0.0025; -0.00012]) with a correlation intensity (r) different from zero (p2 = 0.04). In Tiassalé the correlation was not significant. Haemoglobin and WBC can be considered as key haematological indicators of malaria infection in the study population.
Animation character recognition and character intelligence analysis based on semantic ontology and Poisson equation
Authors: Yang Zirui
Published: October 2022

In order to make a deeper research on the existing animation character recognition technology and improve the existing role intelligent analysis technology, semantic ontology and Poisson equation are combined to apply to the animation character recognition and role intelligent analysis technology. For the three-dimensional model, the mapping relationship between semantic tags and local geometric features is extracted to form an intelligent recognition ontology. In the recognition process, support vector machine (SVM) and local geometric features are used to identify semantic tags, and the recognition analysis is carried out according to the semantic tag driving level. Ensure the consistency of animation character model recognition level. In view of the equal perimeter of the recognition boundary under attitude change, the isoline is defined by Poisson equation. This optimization method makes the recognition boundary smooth and consistent under the change of attitude. In the experimental part, various animation character models under different postures are verified and analyzed, and the consistent hierarchical recognition effect is obtained. Compared with the existing methods, the proposed recognition ontology can solve the problem of adaptive selection of optimization parameters of different models and improve the recognition quality.
Meloidogyne Haplanaria: an Emerging Threat to Tomato Production in Florida

Published: October 2022

The Mi-gene is widely used in different tomato cultivars to resist several Meloidogyne spp. (root-kot nematode; RKN), including M. incognita, M. javanica, and M. arenaria. Tomato cultivars with the Mi-gene are widely used in fields. However, factors such as temperatures, high initial population densities, and gene dosage can interfere with the expression of this gene. In addition, the presence of virulent species of RKN can limit the usefulness of the gene. One of the virulent species is M. haplanaria, which was identified infecting RKN-resistant tomato in Florida in 2015. The objectives of this study were to determine the initial damage threshold of M. haplanaria on tomato under greenhouse conditions and to analyze the impact of temperature and genetic background on virulence in tomato cultivars. The results showed a preliminary damage threshold of three eggs and J2/cm3 of soil. In addition, it was observed that M. haplanaria has a shorter life cycle than the virulent M. enterolobii and can infect, reproduce, and damage homozygous or heterozygous RKN-resistant tomato plants. This research demonstrated that M. haplanaria should be considered highly virulent on RKN-resistant tomato and is an important threat to agriculture in Florida.

Published: October 2022

During a nematological survey in Iraq, in the Bashika area, Ninevah province, an anguinid nematode population was isolated from galls of infected barley plants. The morphological characteristics indicated that the recovered species is identical to Anguina tritici. The barley population of A. tritici was molecularly characterized by sequencing two ribosomal regions (ITS and 18S rRNA genes), and their phylogenetic analyses revealed the newly generated sequences are in sister relation to corresponding sequences of A. tritici from wheat in the Bayesian tree, providing further evidence that the host plant can contribute to the separation of new isolates of plant parasitic nematodes.

The influence of publications in the press about the spontaneous renewal of icons and church domes on the formation of the concept of a miracle among the population of Ukraine in the first half of the XX century
Authors: Butov Illia Stanislavovich , Tomin Nikita Viktorovich
Published: October 2022

The purpose of the study is to reveal the influence of articles about the spontaneous renewal of icons and church domes on the formation of the concept of a miracle among the population of Ukraine on the basis of publications in the Ukrainian press of the early 20s of the XX century. The scientific novelty of the study lies in the fact that for the first time a layer of poorly accessible newspaper publications was analyzed, on the basis of which it was established what information background was formed around rumors about miracles that occurred in 1920-1925, and how it could influence the emergence of the corresponding narratives. As a result, it was revealed that stories about miracles in Ukraine during this period were characteristic of both rural and urban environments, and affected almost all layers of society, including the emergence of a stratum of the population that ironically laughed at miracles. It is shown that miracles very quickly entered into everyday reality, and they ceased to see supernatural features. Concrete examples demonstrate that miracles in this period increasingly began to be left to the mercy of science and technology.
Thinking of a primitive individual: a socio-philosophical analysis
Authors: Fomashin Victor Stanislavovich
Published: October 2022

The purpose of the study is to determine the conditions and mechanisms for the formation of primitive thinking, initially devoid of strict subordination to the means of subsistence for large-scale goals. The scientific novelty of the article lies in the identification of a set of legal regulators within the processes of primitive thinking. As a result, the author identified a transition from the fragmentary epistemological experience of an individual to a logical system, which is reflected in the mechanisms of regulating life in a primitive society. Turning to the works of sociologists, philosophers and culturologists of the XXth century, it is important to highlight metaphor and symbolism as turning vectors of the functioning of primitive thinking.
