A Tripartite Machine Learning Approach for Accurate Prognosis of COVID-19 Patient Survival
Authors: Faruq Aziz
Published: September 2023

Accurate prognosis of COVID-19 patient survival is vital for healthcare decision-making. This research proposes a tripartite machine learning approach that integrates K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and XGBoost for outcome prediction. Our hybrid model exploits the strengths of individual algorithms and combines their predictions using a weighted ensemble. Leveraging clinical data, KNN captures local patterns, SVM finds complex boundaries, and XGBoost enhances overall performance. Experimental results show exceptional precision (0.93), recall (0.93), and F1-score (0.93) for both classes, affirming accurate classification of "Alive" and "Died" cases. The achieved accuracy of 0.93 further demonstrates the reliability of the proposed approach. Our tripartite method holds the potential to enhance COVID-19 survival prediction, providing valuable insights for clinical practitioners and policymakers. This study contributes by seamlessly fusing KNN, SVM, and XGBoost models into a robust predictive tool, thereby aiding medical professionals in informed decision-making for patient care and resource allocation. The demonstrated success underscores the efficacy of a combined approach, highlighting its relevance in accurately predicting patient outcomes.

Authors: Rahmita Budiarti  , Yulianti Lia
Published: September 2023

Menstrual disorders that are often experienced by women such as lower abdominal pain, irregular menstruation, low back pain, and one of them is dysmenorrhea. Dysmenorrhea is a condition where women experience pain during menstruation which has a bad effect causing disruption to carrying out daily activities because of the pain they feel. This condition can last 2 days or more than the length of menstrual days each month. There are several ways that can be done to treat pain non-pharmacologically, including massage therapy, elevating the feet from the body, exercising, regulating diet and applying warm compresses. This study aimed to determine the effect of warm compresses on reducing menstrual pain (dysmenorrhea) in women of childbearing age at the Bungursari Health Center. This study was an experimental research with a one group pretest posttest design approach, obtained by 30 respondents. The sample in this study were all women of childbearing age who experienced menstrual pain (dysmenorrhea) in the Bungursari Health Center, Purwakarta Regency. Warm compresses can reduce menstrual pain (dysmenorrhea) at the Bungursari Health Center, p value=0.002 < α (0.05). Giving warm compresses can reduce menstrual pain in women of childbearing age (WUS). It is expected that the public will gain knowledge about menstrual pain (dysmenorrhea) and can use warm compress therapy as a way to deal with menstrual pain (dysmenorrhea).

High-contrast imaging of debris disk systems permits us to assess the composition and size distribution of circumstellar dust, to probe recent dynamical histories, and to directly detect and characterize embedded exoplanets. Observations of these systems in the infrared beyond 2–3 μm promise access to both extremely favorable planet contrasts and numerous scattered-light spectral features—but have typically been inhibited by the brightness of the sky at these wavelengths. We present coronagraphy of the AU Microscopii (AU Mic) system using JWST’s Near Infrared Camera (NIRCam) in two filters spanning 3–5 μm. These data provide the first images of the system’s famous debris disk at these wavelengths and permit additional constraints on its properties and morphology. Conducting a deep search for companions in these data, we do not identify any compelling candidates. However, with sensitivity sufficient to recover planets as small as ∼0.1 Jupiter masses beyond ∼2″ (∼20 au) with 5σ confidence, these data place significant constraints on any massive companions that might still remain at large separations and provide additional context for the compact, multiplanet system orbiting very close-in. The observations presented here highlight NIRCam’s unique capabilities for probing similar disks in this largely unexplored wavelength range, and they provide the deepest direct imaging constraints on wide-orbit giant planets in this very well-studied benchmark system.
Optimizing the Resolution of Hydrodynamic Simulations for MCRaT Radiative Transfer Calculations
Authors: Arita-Escalante Jose , Parsotan Tyler , Cenko S. Bradley
Published: September 2023

Despite their discovery about half a century ago, the gamma-ray burst (GRB) prompt emission mechanism is still not well understood. Theoretical modeling of the prompt emission has advanced considerably due to new computational tools and techniques. One such tool is the PLUTO hydrodynamics code, which is used to numerically simulate GRB outflows. PLUTO uses Adaptive Mesh Refinement to focus computational efforts on the portion of the grid that contains the simulated jet. Another tool is the Monte Carlo Radiation Transfer (MCRaT) code, which predicts the electromagnetic signatures of GRBs by conducting photon scatterings within a jet using PLUTO. The effects of the underlying resolution of a PLUTO simulation with respect to MCRaT post-processing radiative transfer results have not yet been quantified. We analyze an analytic spherical outflow and a hydrodynamically simulated GRB jet with MCRaT at varying spatial and temporal resolutions and quantify how decreasing both resolutions affects the resulting mock observations. We find that changing the spatial resolution changes the hydrodynamic properties of the jet, which directly affect the MCRaT mock observable peak energies. We also find that decreasing the temporal resolution artificially decreases the high-energy slope of the mock observed spectrum, which increases both the spectral peak energy and the luminosity. We show that the effects are additive when both spatial and temporal resolutions are modified. Our results allow us to understand how decreased hydrodynamic temporal and spatial resolutions affect the results of post-processing radiative transfer calculations, allowing for the optimization of hydrodynamic simulations for radiative transfer codes.
Photo-zSNthesis: Converting Type Ia Supernova Lightcurves to Redshift Estimates via Deep Learning
Authors: Qu Helen , Sako Masao
Published: September 2023

Upcoming photometric surveys will discover tens of thousands of Type Ia supernovae (SNe Ia), vastly outpacing the capacity of our spectroscopic resources. In order to maximize the scientific return of these observations in the absence of spectroscopic information, we must accurately extract key parameters, such as SN redshifts, with photometric information alone. We present Photo-zSNthesis, a convolutional neural network-based method for predicting full redshift probability distributions from multi-band supernova lightcurves, tested on both simulated Sloan Digital Sky Survey (SDSS) and Vera C. Rubin Legacy Survey of Space and Time data as well as observed SDSS SNe. We show major improvements over predictions from existing methods on both simulations and real observations as well as minimal redshift-dependent bias, which is a challenge due to selection effects, e.g., Malmquist bias. Specifically, we show a 61× improvement in prediction bias 〈Δz〉 on PLAsTiCC simulations and 5× improvement on real SDSS data compared to results from a widely used photometric redshift estimator, LCFIT+Z. The PDFs produced by this method are well constrained and will maximize the cosmological constraining power of photometric SNe Ia samples.
New insights on expression and purification of a recombinant luciferase protein from the bioluminescence marine dinoflagellate Pyrocystis lunula

Published: September 2023

Bioluminescence is interesting, among other reasons, for the various technological applications that have been derived from it. Among these applications, developing visualization techniques to record the expression of one or more genes simultaneously in real-time are particularly useful. With this in mind, this study aimed to generate a recombinant Pyrocystis lunula luciferase protein (Luci D2-3 partial CDS). As the main results, i) a fragment of 1467 bp of the luciferase (LCFb) mRNA of the dinoflagellate P. lunula, containing part of domain 2 and all of the domain 3, was cloned in the pET28a vector; ii) the constructed vector was used to transform Escherichia coli to express the recombinant protein and subsequently purify it through an affinity chromatography procedure using a His-Tag; and iii) the purified protein (~50 kDa) was further analyzed by mass spectrometry to confirm its identity. Despite being unable to perform activity tests with the luciferin substrate, the evidence from previous studies indicates that the recombinant protein obtained in this case is enzymatically active. Due to the limited number of currently available luciferases, synthesizing this recombinant protein represents a useful tool, especially in designing expression assays coupled to multiple reporter genes, thus expanding the palette of proteins available for developing this type of biotechnological advances.
Geometric morphometric analysis of the variations in cephalothorax shape of the freshwater prawn Macrobrachium tenellum, Smith (Decapoda Palaemonidae) from two different coastal basins in Oaxaca, Mexico
Authors: García-Guerrero Marcelo , Martínez-Salazar Nathali , Ramírez-Ponce Andrés , De los Santos-Romero Rodolfo
Published: September 2023

Morphological variations of Macrobrachium tenellum prawns from two populations from locations in the Copalita and Colotepec riverine basins in the seashore of Oaxaca, Mexico, were studied with geometric morphometry techniques. The purpose was to find and explain significant differences in shape and size between the cephalothorax and the rostrum. Differences between sexes and populations were intended to prove intra and inter-populations. Results suggest low intrapopulation differences but significant interpopulation variation between specimens from different places, while a regression analysis suggests a higher correlation between shape and size only in males. The higher differences in places between and within sexes could be explained due to differences in environmental pressure. A positive allometry bias in males could indicate a sexual selection mechanism affecting mating.
Impact of isolation on growth performance, behavior, and stress responses in Nile tilapia, Oreochromis niloticus
Authors: Waheed Ahmad , Naz Hina , Wajid Muhammad , Khan Muhammad Saleem
Published: September 2023

The effects of isolation on the growth performance, behavior, blood hematology, and cortisol level of Nile tilapia, Oreochromis niloticus were checked in laboratory conditions. All fishes were closely observed for behavior and growth-related parameters. The weight and diameter of both the control and treatment groups were measured before and after the trial of 28 days using an electronic balance and measuring tape, respectively. At the end of the trial, blood was drawn from the caudal fin to determine some hematological and hormonal parameters. Significant differences were seen in growth performance, cortisol level, and hematology, as weight gain, specific growth rate, relative growth rate, and daily food intake were significantly higher in the control group. In comparison, cortisol levels and feed conversion ratio were significantly higher in the isolated group. White blood cells, lymphocytes, red blood cells, hemoglobin, hematocrit, and mean platelet volume, were significantly higher in the isolated group when compared to the control group. At the same time, the amount of granulocytes, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and platelets was significantly higher in the control group. Isolated fish showed aggressive behavior towards introduced fish from the control group. Isolation increased the cortisol level, which indicates that the fish was stressed. It is concluded that isolation significantly affects the growth performance, cortisol level, and hematology of O. niloticus.
Blue button (Cnidaria: Hydrozoa) distribution and trends in the Mexican Atlantic, based on field surveys and open-access data
Authors: Rojas-Cruz José Elías , García-Dimas José Jair , De la Cruz-Francisco Vicencio , Mendoza-Becerril María A
Published: September 2023

Access to digital technology and software allows the production of a significant amount of biodiversity data, including citizens' species records, combined with field monitoring and standardized surveys, which are valuable to biological sciences; these data can help to know the distribution of organisms like medusozoans. We compiled records of the presence of Porpita porpita from open-access databases, scientific articles, and field observations to know their current distribution on the Mexican Atlantic for the first time. The yearly records of P. porpita increased over time, adding up to 22 records, of which 18 were assigned to citizen science. Most records correspond to 2011-2022, from April to May, and the Veracruz and Quintana Roo states. The records of the species in warm months and states with long shores can be related to an increase in touristic activities and observations by citizens. On the Mexican Atlantic, it is suggested that the use of digital technological devices under citizen science practices for recording P. porpita and its compilation in open-access databases acts as the principal method for tracking the distribution of this species. This work evidenced the need for a solid research framework of knowledge for P. porpita in the Mexican Atlantic, and future research could combine citizen science records and fieldwork records and improve the relationship between biological and oceanographic data to understand their spatial-temporal distribution patterns.

The paper presents an extensive fish sampling dataset spanning a long-term period (weekly) from 2010 to 2019. The data was collected in Lenta Marina, an upstream area in the Minho Estuary of the NW Iberian Peninsula. To capture fish, fyke nets were utilized as the sampling method. This dataset offers valuable insights into the abundance of each collected taxa, recorded per date.

The dataset reports a comprehensive compilation of fish abundance data, providing a detailed record of how the fish community has changed over time. The dataset clearly shows a trend where the amount of fish from invasive taxa exceeds the count of fish from native taxa.
Une autonomie professionnelle sous contrôles : pressions budgétaires et prudentialité en soins palliatifs
Authors: Boisson Marine Jeanne
Published: September 2023

En France, le secteur médical des soins palliatifs a été créé alors que des contrôles budgétaires s’accentuaient dans l’hôpital. Sous l’effet de ces contrôles, on aurait pu s’attendre à ce que cette spécialité régresse. Mais le nombre d’unités de soins a augmenté, la formation à cette spécialité se renforce et sa légitimité ne cesse d’être réaffirmée. Comment un secteur professionnel peut-il être soumis à davantage de contrôles financiers, et gagner tout de même en autonomie ? À partir d’un travail ethnographique réalisé dans une unité fixe de soins palliatifs, cet article éclaire cet apparent paradoxe. Il montre la façon dont les soignants tiennent compte de pressions éthiques et financières à partir de leurs propres règles de professionnalisme, ce qui tend à renforcer l’autorité du secteur. Mais cette autonomie ne peut être préservée que jusqu’à un certain point, celui au-delà duquel la rationalisation extrême des conditions de travail entraîne plutôt une perte de prudentialité.

Histoire/ethnographie, dialogue : l'archive comme terrain
Authors: Ragaru Nadège
Published: September 2023

Résumé Aux appels incessants à l'interdisciplinarité en sciences sociales répondent paradoxalement des partitions de plus en plus tranchées entre champs disciplinaires, ainsi que l'assignation préférentielle, sinon exclusive, de méthodes données à telle ou telle discipline. À rebours de cette vision de la production des savoirs en sciences sociales, je propose une mise en regard de l'enquête de terrain et de la recherche en archives pour mieux faire saillir tant leurs différences que leurs parentés et, inviter, ce faisant, à inventer de nouveaux apparentements entre méthodes et écritures en sciences sociales.

Histoire, société, raison : la controverse entre Eugen Ehrlich et Hans Kelsen sur la sociologie du droit (1992)
Authors: Carrino Agostino
Published: September 2023

En dépit des travaux de quelques spécialistes, la sociologie du droit d’Ehrlich est longtemps restée méconnue, du moins en Europe alors qu’elle a connu un grand succès aux États-Unis et au Japon. Elle a par ailleurs souvent été analysée à travers le prisme de la controverse entre Ehrlich et Kelsen sans qu’on prenne toujours la mesure du retournement que Kelsen a lui-même opéré par la suite. Ce texte, initialement publié en 1992, se propose de situer la sociologie d’Ehrlich dans son contexte, d’en montrer l’importance pour la constitution d’une sociologie du droit empirique et d’en dresser un bilan critique.

Authors: Obbad Noureddine
Published: September 2023

Les migrants qualifiés sont aujourd’hui considérés comme des agents de développement dans leurs pays d’origine et de changements positifs dans les sociétés d’accueil. Ils jouent un rôle important dans le renforcement de la coopération entre les sociétés d’origine et d’accueil et y apportent des contributions positives. Les marocains du monde dans la définition de leur Maroc, la défense de son intégrité territoriale et la contribution à l’investissement dans leur pays jouent un rôle effectif dans le soutien et le renforcement du projet marocain de développement, à propos duquel Mohammed VI évoque le rôle de la communauté marocaine dans son lien avec son pays d’origine. La diaspora marocaine à l’étranger participe activement, partout, à l’innovation, à la recherche, à la production dans tous les secteurs de l’économie, de la vie sociale ou culturelle. Cette diaspora constitue aujourd’hui, avec d’autres, un formidable levier de développement et de croissance dans les pays d’accueil. Elle est aussi un réel potentiel de savoir-faire, de solidarités, de ressources humains et d’investissements pour le Maroc qui contribue activement à son développement économique et social.
Le discours marocain de politique étrangère en perspective géo-historique
Authors: Zaoui Akram
Published: September 2023

Le Maroc, par la voie de son chef de l’Etat, de son ministère des Affaires étrangères et d’autres institutions techniques, s’est engagé dans une politique africaine qui, au lendemain de la pandémie, a semblé prendre le parti des biens communs. Pour expliquer la centralité de la parole ainsi instituée dans la politique étrangère du Maroc, dans ce qu’elle a tout à la fois de politique et de technique, il convient notamment de procéder à un détour par l’importance de la parole et de sa mise en circulation dans l’accrétion géohistorique de l’État-nation moderne. Le présent article propose ensuite de montrer comment la technocratisation du discours public dans l’aire arabe, au lendemain des printemps arabes notamment, s’est greffée à l’idiosyncrasie du système marocain tel qu’il s’est développé, en particulier au lendemain de l’Indépendance. Des exemples sur la façon dont les actes sont joints à la parole dans la politique marocaine des biens communs africains sont donnés à la fin du chapitre. Cette conjonction des actes à la parole sont un défi qu’il conviendra au Maroc de relever pour sa propre population et celle du continent – il en va, en substance, du crédit qui pourra être fait à cette parole.
Risque de régression de l’ajustement de l’imago des membres d’un groupe : réactivité résiliente du leader
Authors: Brun Gilles , Ducatteeuw Philippe
Published: September 2023

Toute personne qui intègre un groupe le fait nécessairement avec un bagage : des besoins biologiques, des besoins psychologiques, des pulsions, des modèles répétitifs de comportement, une expérience passée et des capacités d’ajustement. Le franchissement de la frontière externe du groupe souligne l’importance du processus psycho-dynamique progressif et non linéaire d’ajustement de l’imago. Le leadership psychologique a la responsabilité de veiller en continu à cette dynamique des représentations mentales de chacun des membres du groupe. Face aux différents risques résultant de la tension psychologique engendrée par l’écart entre persona et personnalité, à cette turbulence identitaire qui provoque une régression d’imago, sa réaction est essentielle. Il lui revient de co-construire les formes et conditions d’un dialogue respectueux de la persona de chacun et favorable à la résilience individuelle et collective, de mener le processus de ré-ajustement des imagos de chacun des membres du groupe.

Authors: Sahagun Miguel A. , Ortiz-Rodriguez Fernando , Medina-Quintero Jose-Melchor
Published: September 2023

In today's global economy, emerging economies play a very important role in the production chain. Countries such as China and India have become competitive participants in the global market. The labor force in these emerging markets has developed new skills, leading developed economies such as the United States to move important areas of their production chain into these countries. This phenomenon had reached Mexico as well and multiple cases of salary and wage inequality could be found. Thus, this research tries to establish a frame that could help better understand the effect that salary and wage inequality play in the leadership-productivity relation among middle management supervisors within the manufacturing industry at the Mexico-US border. A questionnaire was developed and applied to middle management supervisors on both sides of the border (Mexico and the US). The main contribution of this study is to help better understand the impact of salary and wage inequality among middle management supervisors.

Enterprise resource planning (ERP) is a type of software that businesses use to handle standard business processes including accounting, purchasing, project management, risk management, and supply chain management. ERP, which lets users observe daily operations and changes, is used by many organisations and academic institutions. In many schools and institutions, it is also used to give students access to information and updates about things like attendance, daily schedules, exam results, and other things. However, accessing the current generation of ERPs, which are widely used in colleges and universities, might be difficult for blind students. The solution to this problem is to develop a voice assistive application that links to the college/university database and allows visually impaired users to use voice commands to retrieve the data. With the use of this application, students may submit voice commands, and the user will hear the output as audio based on the input.

Authors: Perera Sarath D.
Published: September 2023

Treatment of the ligand 3,4,5,6-tetraphenyl-2,2´-bipyridine (LH) VIII with HAuCl4 in acetonitrile afforded the cyclometallated square-planar Au(III) complex [LAuCl]ClO4 (7) containing the anionic tridentate (N∧N∧C) ligand, via orthometallation. Treatment of (7) with 4-dimetylaminopyridine (DMAP) and AgClO4 in acetonitrile produced [LAu(DMAP)][ClO4]2 (8), showing the same coordination mode. Analogous complex [LAu(PPh3)][ClO4]2 (9)was prepared by using PPh3 instead of DMAP. Reaction of VIIIwith HAuCl4 at room temperature in aqueous acetonitrileresulted the non-cyclometallated Au(III) complex [(LH)AuCl2]Cl(10), in which VIII is a bidentate (N∧N) ligand. Treatment of VIIIwith the filtrate obtained by mixing [AuCl(PPh3)] and AgO2CCF3 in acetone resulted the non-cyclometallated Au(I) complex[(LH)Au(PPh3)]O2CCF3 (11) having bidentate (N∧N) ligand. Abovecomplexes were adequately characterized by a combination ofelemental analysis, IR, Mass and NMR spectroscopy. The X-raycrystal structures of (7) and (8) were determined.

Robson classification is a globally recognised method in systematically classifying all pregnant women admitted for delivery. The World Health Organization (WHO) and the International Federation of Gynecology and Obstetrics (FIGO) recommend the Robson classification as a global standard for assessing, monitoring and comparing CS rates within and between heath care facilities, over time. Continuous audit of admission and delivery data is an essential component in service quality improvements including caesarean section rates. Previously we have reported data acquisition and quality as the main problems in carrying out a continuous audit in absence of a centralised electronic database. We developed and validated an app based on the hybrid JQuery Mobile (JQM) technology with an option for scalability to the regional and national level in the future for real time acquisition and analysis of admissions data in a maternity care setting using Robson classification.

Sjögren’s syndrome is systemic autoimmune disease characterized by lymphocytic infiltration of various organs with wide frequency of pulmonary involvement. Diffuse cystic lung disease in Sjögren’s syndrome is a rare condition and requires differential diagnosis with other cystic pathologies such as lymphangioleyomiomatosis or Langerhans cell histiocytosis. Probe-based confocal laser endomicroscopy (pCLE) is a method of in vivo investigation of airways and lung tissue on microscopic level during bronchoscopy. We used this method in diffuse cystic lung disease caused by Sjögren’s syndrome. The pCLE image showed a large number of fluorescent cells presumably lymphocytes in bronchioles, dilated alveolar spaces with fluid and thin alveolar walls. We think that the presence of the bronchiolar cells pattern can be used to differentiate between the pulmonary manifestations of Sjögren's disease and other cystic lung diseases.
No-synovectomy improves the health-related quality of life after total knee arthroplasty: A randomised clinical trial
Authors: Abdeldayem Sherif Mostafa , Younis Ahmed Saeed
Published: September 2023

Background

This study assessed the clinical outcomes of total knee replacement with and without synovectomy among patients with osteoarthritis.

Methods

A randomised controlled trial of 70 patients with advanced knee osteoarthritis was conducted by individually randomizing (simple randomization) patients to either no synovectomy (group 1 n=35) or synovectomy (group 2 n=35). Clinical outcomes were assessed by Western Ontario and McMaster Universities Arthritis Index, WOMAC score, knee pain by visual analogue score, health related quality of life by Short Form 12, postoperative blood loss, and hemoglobin levels immediately after surgery and one year postoperative.

Results

Postoperatively, The WOMAC score was 87 (82, 97) in group 1 and 84 (76, 96) in group 2. The VAS score was 6 (5.00, 8.00) and 7 (5.00, 8.00) in group 1 and 2 respectively. The physical composite score (PCS) of the SF-12 score was 52 (46, 56) in group 1 and 50 (43, 54) in group 2. The mental composite score of the SF-12 was 58(55, 61) and 51 (45, 57) in group 1 and 2 respectively with significant difference between groups. The median hemoglobin drop was 1.7 (1.35, 2.00) grams in group 1 and 3 (2.45, 3.30) grams in group 2. The median drain blood loss was 250 ml (200, 350) and 800 ml (450, 1200) in group 1 and 2 respectively. Patients in group 1 had a better flexion range than group 2.

Conclusion

Total knee arthroplasty performed without synovectomy reduces postoperative blood loss, improves the flexion range and patients’ quality of life scores.
Evaluation of treatment of nonunited middle third scaphoid fractures using threaded Kirschner wires fixation with iliac bone grafting
Authors: Abosalem Ahmed , Shams Ahmed , Samy Mohamed
Published: September 2023

Objectives

To evaluate the results of iliac bone grafting with threaded Kirschner wires (K-wires) fixation in treating of nonunited middle third scaphoid fractures.

Background

Scaphoid nonunion is a common complication after scaphoid fractures as it is an intra-articular fracture with high fracture mobility and instability. In addition, the scaphoid is devoid of periosteum along with impaired vascularity. Scaphoid nonunion results in carpal collapse with secondary osteoarthritis. To avoid that, the aim of treatment should be to enhance the biology of fracture through bone grafting and provide adequate stability of the fracture in an anatomic alignment.

Patients and methods

This study is a prospective case series of 30 patients with nonunited middle third scaphoid fractures admitted to an academically supervised trauma center from June 2018 to June 2020. They were managed by open reduction, refreshment of the scaphoid nonunion site with iliac crest bone grafting, and threaded K-wires fixation in an anatomical alignment. The mean age was 28.58 ± 4.47 years. Postoperative clinical outcomes were evaluated using the Quick disabilities of arm, shoulder and hand (DASH) score, and modified Mayo wrist score. Postoperative radiological union and scaphoid alignment were assessed. The minimum period of follow-up was one year.

Results

One year postoperatively, the mean modified Mayo wrist score was 81.67 ± 9.39 and the mean Quick DASH score was 25.67 ± 14.97. Radiologically, the union was achieved in 86.7%. The mean union time was 11.92 ± 1.54 weeks.

Conclusions

Threaded K-wires fixation with iliac bone grafting is an effective method for treating nonunited middle third scaphoid fractures.
Caesarean surgery and ovariohysterectomy in a precocial rodent Octodon degus
Authors: Correa Loreto , Aleuy Oscar Alejandro , Espinoza Angelo , Soto-Gamboa Mauricio Rodrigo
Published: September 2023

The common degu (Octodon degus) is a trendy rodent pet in Europe and the USA, but is also widely used in scientific research. Information about degu housing, nutrition, behavior, disease diagnosis, and disease treatment is abundant in scientific literature. However, information on reproductive management, such as cesarean section, ovariohysterectomy, ovariectomy, and orchiectomy, is scarce and anecdotal. Our general objective was to develop a protocol for cesarean section and ovariohysterectomy for degus. Our results indicated that cesarean post-surgical survival was 100% for mothers and 97% for offspring, while ovariohysterectomy female postsurgical survival was 100%. Cesarean surgeries lasted an average of 61.82 min, while ovariohysterectomies lasted an average of 32.65 min. The initial recovery times for cesarean sections and ovariohysterectomies were an average of 8.18 and 5.53 min, respectively. The full recovery time for cesarean section was an average of 50.18 min, whereas that for ovariohysterectomies was an average of 15.38 min. These results suggest that both protocols are viable for use in veterinary clinics that use mid-level equipment. We discuss our results with data from other rodent species and rabbits and with orchiectomy and ovariectomy procedures practiced in degu. Finally, we discuss in detail four critical considerations for cesarean and ovariohysterectomy surgeries performed on small mammals such as degu.

Published: September 2023

Приводятся несколько наблюдений, касающихся так называемых обратимых многочленов, введенных и изученных в серии статей по математической физике и теории особенностей. В частности, рассмотрены вещественные версии обратимых многочленов и исследованы инварианты связанных с ними изолированных особенностей гиперповерхностей. По определению такой многочлен является взвешенно однородным и его градиентное векторное поле $\operatorname {grad}f$ имеет изолированный нуль в начале координат; следовательно, корректно определен его индекс $\operatorname {ind}_0\operatorname {grad}f$. Этот индекс, называемый индексом градиента многочлена, является главным объектом исследования в работе. В частности, дана эффективная оценка модуля индекса градиента $\operatorname {ind}_0\operatorname {grad}f$ через взвешенно однородный тип многочлена $f$ и исследована ее точность. Для вещественных обратимых многочленов от двух и трех переменных найдено полное множество возможных значений индекса градиента. В качестве приложения в случае трех переменных приведен полный список возможных топологических типов слоев Милнора вещественных обратимых многочленов, обобщающий недавние результаты Л. Андерсена по топологии изолированных вещественных особенностей гиперповерхностей. В заключение представлены несколько открытых проблем и гипотез, возникших в ходе работы.
