PRICE SUSTAINABILITY OF AGRARIAN SECTOR IN BULGARIA
Authors: Petrov M.
Published: May 2024

Recent years were marked by several crises of different characteristics: epidemics, energy sources, and crises in raw materials. We are witnessing how these turbulences transfer to the means of production of agricultural companies and subsequent transfer to the prices of food for people and animals. The main AIM of this study is to determine the inflation force that is hitting agricultural companies and to study their capability of sustaining their production levels. The pressure on prices in the agrarian sector originated not only from the inflation in the Bulgarian economy but also due to the turbulences in international food markets and political instability in the European continent. The METHOD of the study is a systematic analysis of statistical data regarding the agrarian production and prices of agrarian products in the markets of Bulgaria. RESULTS of the study show that there are several factors that are pressing the prices of agrarian products, pushing inflation at higher levels. Agrarian producers have a low capability to sustain their production levels and are forced to reduce or change the type of their production.
COMPARATIVE ANALYSIS OF COOPERATIVE AND CORPORATE BUSINESS MODELS IN BULGARIIAN AGRICULTURE

Cooperative is a form of cooperation and mutual assistance to achieve a common goal. Through the cooperative model, prosperous cooperation in economic activity is achieved with real economic benefit. The collective management of the factors of production under market conditions is most often a manifestation of some of the following postulates, that when the individual size of the factors are highly limited and the possibilities for their increase are not profitable, the need for association is manifested. According to F. Raiffeisen's maxim, which states that "when one can't achieve something alone, everyone can do it together", referring to the cooperation of their efforts. In addition, when the production factors owned by the individual owners have technological qualities that allow them, when combined, to perform the relevant work more efficiently and optimally, the LLC as a legal organizational form is suitable in agricultural activity, when there is ownership of property and land fund, which can hardly be differentiated. In order to fairly organize the relations and overcome the contradictions between the owners, the fragmentation of the land, it is necessary to apply this structural form of the enterprise. The effectiveness of this form of enterprise is also expressed in economic cases of lack of financial capital for its investment in expensive equipment and facilities that are beyond the capabilities of an individual individual. In this regard, the partners in the LLC can be not only natural persons, but also legal entities.

Bevezetés: A proximalis humerustörések előfordulása gyakori,
melyben további emelkedő tendencia várható. Az érintettek többsége az idősödő,
ezáltal már gyakran gyengült csontszerkezettel rendelkező populációból kerül ki.
Az elmozdult, többrészes töréssel rendelkező esetek adekvát kezelése gyakran
kihívást jelent, különösen a már osteoporosis által is érintett felkarfej
esetén. Műtéti ellátása során a leggyakrabban a szögstabil lemezrendszerekkel
történő rögzítés használatos, a komplikációk azonban nem elhanyagolhatók, az
elért funkcionális eredmények pedig gyakran szerények. Az intra-, illetve
posztoperatív szövődmények csökkentésére, illetve a sérülés utáni funkció lehető
legjobb helyreállítására az elmúlt időszakban fokozott figyelem fordult.
Célkitűzés és módszerek: A valgizáló helyzetű szögstabil
lemezelési módszert intézetünkben 2019 vége óta alkalmazzuk a már gyengült
csontszerkezettel rendelkező multifragmentális felkarfejtörések rutinszerű
kezelésében. Jelen vizsgálatunk során 46, 65 év feletti páciens (életkor 76,1 ±
7,9 év) 47 három-, illetve négyrész-törésének lemezelése mellett elért rövid
távú funkcionális eredményeinket értékeltük retrospektív módon.
Eredmények: Vizsgálatunk során az esetek 76%-ában
tapasztaltunk jó, 120° feletti abductiós és flexiós értékeket. A Constant–Murley
Score összesített eredménye 80,2 ± 12,5-nek mutatkozott. A 17,3 ± 9,4 hónapos
utánkövetés során 23 esetben kitűnő, 14-nél jó, 7-nél kielégítő, míg 3-nál
gyenge funkcionális eredményeket tapasztaltunk. A funkcionális eredmények
szignifikáns kapcsolatot mutattak az életkorral (p = 0,009), illetve az
alapbetegségekkel (p = 0,016), azonban a törés jellegétől, a BMI-től vagy a
sérült oldaltól függetlennek mutatkoztak. Az összesített komplikációs rátát
6,4%-nak, a revíziós rátát 4,3%-nak találtuk. Neurológiai deficitet,
pseudoarthrosist vagy avascularis felkarfejnecrosist nem észleltünk.
Következtetés: Tapasztalataink szerint az általunk az
időskori proximalis humerustörések esetén alkalmazott valgizáló helyzetű
szögstabil lemezes osteosynthesis – az optimalizált fej-, illetve lemezhelyzet
miatt – az esetek többségénél kiemelkedően jó funkcionális eredményeket
biztosít, illetve jelentősen csökkenti a posztoperatív komplikációk
előfordulását. A módszer kifejezetten jól alkalmazható elmozdult három-, vagy
négyrész-törések esetén, gyengült, osteoporoticus csontszerkezet mellett is. Orv

Clefts of the lip and palate remain one of the most common congenital malformations. Bilateral cleft is considered the most complex form of the defect. There is no consensus on the timing and method of surgical treatment. However, most publications focus on the two-stage method of defect closure and recommend complete correction by 24 months of age. This clinical case deviates from the commonly accepted approach to treating children with bilateral clefts of the lip and palate. The patient sought medical help at a late age, specifically at 11 years old, due to a number of subjective and objective reasons. The aim - based on a clinical case, analyze the timely and qualitative provision of medical care, the difference in the quality of life before and after surgical intervention in patients with the described pathology. The first stage was performed at the age of 2 years. After preoperative preparation, including antibiotic therapy guided by throat swabs, the patient underwent a series of surgical procedures, including complete dissection of soft palate muscles, intravelar veloplasty, formation of a Vomer flap, and meticulous closure of the palate defect layer by layer. One month after the surgery, the patient exhibited soft palate movements (which were absent before surgery), improved feeding, and continued speech therapy sessions, resulting in significantly improved pronunciation. Analysis of this clinical case will contribute to a better understanding of the approach to treating children with bilateral clefts of the lip and palate. Timely referral of patients for comprehensive treatment, including surgical correction, subsequent orthodontic treatment, speech therapy sessions, possible psychological rehabilitation, and so on, is crucial in children with bilateral clefts of the lip and palate. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies.

Аn early consideration in pediatric patients with extrahepatic portal vein obstruction (EHPVO) is to be given for mesoportal shunt. A careful investigation is required to prove intrahepatic portal system patency. Conventional noninvasive imaging is not adequately reliable in assessing patency of the intrahepatic portal venous system. Retrograde portography in children brings additional invasive procedure. Antegrade, direct intraoperative digital subtraction angiography for mesoportal shunt feasibility assessment is poorly presented in literature. Aim - to improve the rate of success of mesoportal shunting in children with EHPVO by analyzing our own experience in intraoperative digital subtraction angiography of the intrahepatic branches of the portal vein for the final assessment of the mesoportal shunting feasibility. Materials and methods. 7 pediatric patients with EHPVO were selected for the study. Angiographies and surgeries in selected patients were performed within single center in a period from May 2022 to July 2023. Mean follow up of successful mesoportal shunting was 12.38±1.46 months. Results. All patients were males. Men age at surgery was 8.71±1.72 years. 5 (71.4%) patients manifested bleeding episodes as the first sign of portal hypertension. In all patients ultrasound revealed splenomegaly and suspected portal hypertension for reduced volumetric portal flow. All 7 patients had high grade. Liver function was normal in all patients, and in none thrombophilia was confirmed. CT scans suspected patent left intrahepatic branch (Rex-zone). Digital subtraction angiography approved mesoportal shunt feasibility in 4 (57.1%) patients. The follow up period was 13.5±2.9 months. Conclusions. Digital subtraction angiography of intrahepatic portal vein is effective visualization method to achieve with radiologic evidence of intrahepatic portal branches patency and make the decision on mesoportal shunting when favorable anatomy proved. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution.

Road traffic accidents cause significant trauma to the population and are one of the main causes of mortality in working age. The novelty of the study risk-oriented patterns of severity of damage and mortality of victims of road accidents have been established. The aim - to create of a fundamental basis for the formation of clinical routes and protocols for victims of road accidents by establishing and verification the relationship between the severity of damage and the death of the victims. Material and methods. An analysis of 1,696 cases of road traffic injuries was carried out, and the standardized New Injury Severity Score (NISS) assessment system was used. Results. A probable, but indirect dependence of the clinical effective risk of a negative outcome of the traumatic process in victims on the severity of the damage was established. It was established that the sign of participation in the traffic the formation of clinical effective risks of a negative outcome of the traumatic process, starting with the severity of damage according to the NISS with 25 points. With the same qualitative characteristics, pedestrians have the highest risk of fatality, drivers have the lowest risk. The synergistic effect of the severity of damage and the clinical and anatomical form of the injury was established. Conclusions. The risk of a fatal outcome of a road traffic injury in general directly depends on the severity of damage to the victim, although the dependence is not direct. The clinical and anatomical form of damage together with the severity of the damage have a synergistic effect on the formation of the clinically effective risk of mortality in victims of a road traffic accident, and the predominant influence is the clinical and anatomical form of damage.

Hirschsprung disease and chronic intestinal pseudo-obstruction (CIPO) in children are the most common and severe disorders of gastro-intestinal tract motility. While the problems connected with the Hirschsprung disease widely coverage in native literature, the publications that devoted the CIPO absent. Aim of the study was to analyze the literature data that devoted to the diagnosis and treatment of children with CIPO. Intestinal pseudo-obstruction refers to heterogeneous groups of disorders with a similar phenotypic presentation characterized by obstructive intestinal symptoms in the absence of true anatomical obstruction. CIPO classification based on the primary dysfunction: affected enteral nervous system (neuropathy), affected smooth muscle (myopathy) or interstitial cells Cajal (mesenchymopathy). Besides that, the intestinal pseudo-obstruction is divided into primary and secondary, congenital and acquired, total and segmentary. The main clinical features, methods of investigation in suspected CIPO such as radiological (roentgenography and roentgenoscopy, computed tomography, cine magnetic resonance), endoscopic, manometry, pathohistological, etc. were listed. The main principles of nutrition support, conventional therapy, and surgical management were presented. Conclusions. CIPO is a severe disorder of gastrointestinal motility that caused by various factors, which can be congenital and/or acquired. Diagnosis of CIPO based on the results of clinical, instrumental, and pathohistological investigation. The management of children with CIPO should include nutritional support, conventional therapy, and, for the clear indices, surgical correction. No conflict of interests was declared by the authors.

Bladder-ureteral reflux is a pathological condition in which there is a periodic and/or permanent retrograde flow of urine from the bladder into the urinary tract due to a malfunction of the anti-reflux mechanism of the vesicoureteral segment. The aim - to study etio-pathological mechanisms of vesicoureteral reflux in children to improve diagnostic and therapeutic tactics. Every year in Ukraine, 3,600-3,700 children with congenital defects of the urinary tract are diagnosed, with 1/3 of the defects occurring in their upper parts. According to statistics, there are 40-50 cases of congenital diseases of the urinary system per 1000 newborns. There are reports that the frequency of vesicoureteral reflux in the general pediatric population exceeds 2%. According to modern data, vesicoureteral reflux accounts for 0.1% to 1.0% of all pathology in the general pediatric population, accounting for 10% of all diseases of the urinary system in hospitalized children. Bladder-ureter is the initial link in the chain of pathological reflux in the urinary tract. The leading importance of the mechanism of the vesicoureteral reflux belongs to the study functional anatomy of the urinary tract as a whole. Bladder-ureteral reflux is most often detected during urination against the background of increased intravesical pressure, but it can occur during any of the stages of the urination cycle. Nephrosclerosis with vesicoureteral reflux is formed in 30-60% of cases, which leads to the development of the terminal stage of chronic renal failure in 25-60% of patients due to a decrease in the functional renal reserve, as an indicator of the compensatory capabilities of the kidneys. Conclusions. Review of literature dataregarding the structure and functional anatomy of the vesicoureteral segment convincingly testifies to the complexity and multi-level organization of its antireflux mechanism. Therefore, any further research in this direction will undoubtedly contribute to a deeper understanding of the normal functioning of this complex anatomical part of the human urinary system, which will allow the development and implementation of the latest physiological treatment methods in the practice of pediatric surgeons.

Introduction. Early postoperative recovery in pediatric practice is an important problem for patients and the health care system as a whole. Aim: to investigate the quality of postoperative recovery of children after various types of surgical interventions. Materials and methods. The study involved 150 children who underwent trauma (group I), abdominal (group II) and urological (group III) surgical interventions. Each of these groups was divided into two subgroups: Іb (n=17), ІІb (n=19) and ІІІb (n=24) subgroups - included children who received intravenous lidocaine in the perioperative period, control Ia (n=23), IIa (n=29) and IIIa (n=38) subgroups - included children to whom lidocaine was not prescribed. The PaedQoR-15 questionnaire was used to assess the quality of postoperative recovery. Results. The use of perioperative intravenous lidocaine infusion is associated with an increase, compared to the control group, in the PaedQoR-15 score by 10.6% at 24 hours after trauma surgical interventions, by 21.3% and by 17% after abdominal and urological surgical interventions due to a decrease in the frequency of postoperative nausea after abdominal surgery, skin itching after all analyzed types of surgical treatment, a reduction 26.7% reduction in the time until the first gas release and by 19.3% reduction in the time until the appearance of bowel movements/defecation after abdominal surgery. It was observed that the stay of patients in the intensive care unit (ICU) was reduced by 120 minutes after trauma surgery and by 1.8 times after abdominal surgery. Conclusions. Perioperative lidocaine infusion may be useful in rapid postoperative rehabilitation programs. The research was carried out in accordance with the principles of the Declaration of Helsinki. The study protocol was approved by the Local Ethics Committee of all participating institutions. The informed consent of parents and children was obtained for conducting the studies.

Published: May 2024

In recent years, soft material microlasers have attracted great interest for their simple fabrication and potential in flexible photonic devices. Particularly, ink-jet printing technology offers an efficient method for the production of uniform microlasers. However, the ink-jet system is generally complex and expensive. In this work, we have successfully used a cost-effective standard printer for microlaser creation. By employing dye-doped glycerin-water for the printing ink, we can fabricate uniform dome shaped structures, the so-called hemispheres, with diameters from 35 to 70 µm on a hydrophobic coated dielectric mirror. Under optical pulse pumping at 532 nm, these hemispheres exhibit lasing emission with clear modes. The lasing mechanism is studied and ascribed to whispering gallery mode. Due to low optical loss, we achieve a lasing threshold of 32 µJ/mm² and a quality factor of 2100. Our method can be applied to diverse soft matter microlasers and the fabricated microlasers are promising for sensing applications.

The number of desk workers who frequently conduct their jobs at home has increased dramatically during Covid-19. Work-from-home flexibility makes it attractive for workers and companies, resulting in a “Work-Style Reform” after the Covid-19 pandemic. However, the quick conversion of home spaces into workplaces cannot always sufficiently respond to users’ visual comfort and daylight performance needs which are primary contributors to occupant well-being and productivity. Therefore, this study adopts a mixed-methodology method that integrates parametric thinking, biomimetic, conceptual design, kinetic strategy and the DIVA approach to develop a real-time parametric-generative circular design for multi-objective adaptability that optimizes visual comfort and electric lighting energy efficiency for multiple occupants simultaneously. Parametric simulations of 1458 different options (five different runs per case: a total of 7290) were conducted to assess how the louvers perform regarding daylight, glare, and electric energy usage. Implementing an interactive kinetic louver greatly improved daylight performance in all orientations while simultaneously avoiding visual discomfort for multiple occupants. Furthermore, the use of this façade modification resulted in a substantial decrease in electrical lighting energy consumption, reducing the values from 14.22 to 0.2 kWh/m2/year, 8.1 to 0.18 kWh/m2/year, and 12.88 to 0.18 kWh/m2/year for South, East, and West orientations, respectively. Integrating users' lighting level preferences and the dynamic transitory sensitive area on the façade considerably reduces electric lighting consumption by around 99% compared to the ASHRAE 90.1 standard's lighting profile.

Within five years after myocardial infarction (MI), a third of patients have secondary major adverse cardiovascular events (MACEs). The first randomized clinical trials to show the effectiveness of anti-inflammatory strategies in the prevention of MACEs are CANTOS, COLCOT and LoDoCo2. These studies have identified an effective therapeutic target — the NLRP3 inflammasome. The results of COLCOT and LoDoCo2 led to colchicine becoming the first anti-inflammatory drug to be included in clinical guidelines for the treatment of patients with coronary artery disease (CAD). However, considering colchicine in routine clinical practice requires the cardiologist to have knowledge of the basic molecular mechanisms of inflammation in cardiovascular diseases. The review discusses current data on inflammation and the NLRP3 inflammasome in the pathogenesis of CAD and MI, results and issues of their application in clinical cardiology.

Aim. To identify the relationship of different albuminuria levels with paraclinical signs of congestion on admission and discharge and with the prognosis of acute decompensated heart failure (ADHF).

Material and methods. Patients hospitalized with ADHF were included. Albuminu­ria level was assessed on admission and discharge. Patients were divided into groups according to albuminuria level (A1, A2, A3) according to KDIGO guidelines. Among the congestion parameters, the following were assessed: N-terminal pro-brain natriuretic peptide (NT-proBNP), lung ultrasound examination (BLUE protocol), venous congestion according to the VExUS ultrasound protocol (inferior vena cava, portal, hepatic and renal veins). The primary endpoint was a composite of all-cause death and rehospitalization for ADHF within 180 days of discharge.

Results. The final analysis included 180 patients. The prevalence of A1, A2 and A3 albuminuria at admission was 50%, 39%, 11%, respectively. A greater degree of albu­minuria was associated with worse renal function at admission and discharge. Pati­ents with increased albuminuria on admission had higher NT-proBNP and a greater number of B-lines on pulmonary ultrasound in on admission and discharge, and a higher degree of complex venous congestion and renal vein congestion on VExUS on admission. A3 albuminuria at admission and discharge was associated with an increased risk of poor long-term prognosis (hazard ratio (HR) 3,551; 95% confidence interval (CI) 1,593-7,914; p=0,002), (HR 4,362; 95% CI 1,623-11,726; p=0,004).

Conclusion. In patients with ADHF, the albuminuria level on admission is associated with the severity of congestion upon admission and discharge. A3 albuminuria at admission and at discharge is a predictor of long-term poor prognosis within 180 days after discharge.

Aim. To study the relationship of lipitension and cardiometabolic risk (CMR) factors in young people.

Material and methods. The case-control study on general obesity (GO) (overweight — 33,3%, GO — 33,3%) included 191 patients (Me=35,0 [30,0-39,0] years; F/M=97(50,8%)/94(49,2%)) without cardiometabolic diseases, comparable by sex and age. The prevalence and characteristics of lipitension were studied, taking into account the features of dyslipidemia and increased blood pressure (BP). Depending on the presence of lipitension, 2 groups were identified in which the CMR factors were studied: GO and abdominal obesity (AO), visceral fat, prediabetes, insulin resistance, increased C-reactive protein (CRP), hyperuricemia, glomerular filtration rate changes. Data were processed using SPSS Statistics 26.

Results. Overall, the incidence of increased BP was 36,1%, hypertension (HTN) — 16,2%, and dyslipidemia — 73,3%. Lipitension was diagnosed in 25,1% of patients. At the same time, increased BP and HTN without combination with dyslipidemia were detected less frequently (13,1% and 5,2%, respectively). Dyslipidemia without increased BP and HTN, on the contrary, is more common (48,2%). Lipitension is more often diagnosed in men than in women — 32 (66,7%) and 16 (33,3%), p=0,005; [odds ratio=2,6; 95% confidence interval: 1,32-5,18]. In patients with lipitension, 43,8% were diagnosed with HTN, while the remaining 56,2% had BP ≥130/85 mm Hg. In the structure of dyslipidemia in lipitension, 79,2% had abnormalities in ≥2 lipid parameters, of which increased levels of low-density lipoprotein cholesterol (LDL-C) and hypercholesterolemia (78,3%) were most often detected. Persons with lipitension more often had AO (31,2%), increased glycated hemoglobin (HbA1c) >6% (39%) and insulin resistance (36,2%) than those without lipitension (p=0,026, p=0,018, p=0,044, respectively). With lipitension, a higher level of visceral fat (Me=8 [6-9] units) and HbA1c (Me=5,6 [5,1-6,0]%) was established than without it (Me=6 [4-9]U and Me=5,4 [5,1-5,9]%, respectively p=0,000 and p=0,018).

Conclusion. Increased BP and HTN are more often found in combination with dyslipidemia than as an independent risk factor. In lipitension, the largest number of patients had ≥2 lipid metabolism disorders, most often represented by increased LDL-C and hypercholesterolemia. The presence of lipitension was associated with AO, increased HbA1c, and insulin resistance.

Authors: Gulina Nadezhda , Shchegoleva Natalia , Kuznetsov Maxim
Published: May 2024

The issue of safety and traffic potential on public motorways often arises due to large-sized vehicles such as buses, agricultural machinery, and road articulated vehicles stopping on the roadsides. This is caused by the number of logistic transportations between the territorial subjects of the Russian Federation, which has increased recently due to the increase in the number of warehouses and, as a consequence, the increase in the number of heavy and full-size vehicles. The problem is especially acute at high traffic intensity, when four vehicles are simultaneously located on a two-lane road in one transverse profile. In this article the authors consider the safety analysis of cross profile elements of a motor road on safety maintenance of road traffic at a collision of a passenger car on the car stopped on the roadside with simultaneous separation on a two-lane motor road from the position of the risk theory. This approach to the risk calculation methodology is developed within the framework of the scientific direction «Design, construction and operation of motorways under the condition of ensuring traffic safety taking into account the risk theory». The purpose of the calculation is to check the safe stopping possibility of large-tonnage vehicles on roadsides of II, III and IV categories on the basis of risk-oriented approach according to geometric elements normative dimensions of the public roads cross profile.

Published: May 2024

Resumo: O objetivo deste artigo consiste em analisar como a interpretação marxiana acerca da ontologia e da filosofia política hegelianas reflete na sua crítica da economia política capitalista, com ênfase para como Marx elabora a relação entre trabalho e sociabilidade a partir de Hegel, e como esse processo influencia a crítica marxiana da forma valor (Wertform) como substância social do processo de acumulação do capital. A metodologia utilizada foi a pesquisa bibliográfica, guiada pela leitura imanente das obras marxiana e hegeliana.

Fluxo de Campo Elétrico – Duas abordagens
Authors: Cavalcanti Gildo , Silva Luiz A.
Published: May 2024

Neste trabalho discutimos a solução para o cálculo do fluxo de campo elétrico produzido por uma carga puntiforme através de uma superfície plana baseado na aplicação direta da definição de fluxo e outra através de uma “extensão” da lei de Gauss. A solução rígida feita a partir da definição de fluxo de campo elétrico rendeu um cálculo trabalhoso, e produziu o mesmo resultado que pode ser obtido a partir da simplificadora aplicação da lei de Gauss, que produz uma solução quase imediata para o problema estudado. Neste trabalho são discutidas também abordagens didáticas distintas para a apresentação da lei de Gauss e qual delas melhor conferiria ao aluno um grau de maturidade maior sobre o tema e uma visão ampliada desta lei. A discussão envolve a questão do ensino-aprendizagem a partir da aceitação-repetição versus demonstração-indução e suas consequências.

Authors: Herschmann Micael , Lacombe Fabiano
Published: May 2024

Resumo Tomando como referência não só uma breve revisão da literatura especializada, mas também as pesquisas realizadas nos últimos anos, busca-se contribuir com o debate teórico-conceitual que envolve a noção de ecossistema na contemporaneidade. Ao mesmo tempo, sugerimos neste trabalho o emprego do conceito de Ecotranssistema Musical-Midiático (EMM), aqui cunhado como noção profícua que não apenas possibilitaria se repensar as dinâmicas musicais e comunicacionais de maneira articuladas, mas também sinalizaria aos pesquisadores a relevância fundamental do trabalho de investigação de campo (mesmo este sendo precário e limitado), isto é, a importância de se seguir os rastros e vestígios dos atores humanos e não humanos nas dinâmicas de reagregação social.
A família Margarina tem melanina? Análise interseccional semiótica das representações familiares na publicidade1
Authors: Fernandes Pablo Moreno
Published: May 2024

Resumo O artigo discute as representações familiares negras em anúncios de revista e em conteúdos veiculados no Instagram pelas 10 marcas mais valiosas do Brasil, segundo o ranking Interbrand, no intervalo 2018-2020. Por meio da análise interseccional semiótica dos materiais, verificamos como são representadas as famílias negras, sob uma perspectiva de conjugalidade, racialidade e orientação sexual. Os resultados obtidos, apesar de alguns pontos contraintuitivos, comprovam o lugar interseccional do racismo para mulheres negras na perspectiva da solidão, bem como o silenciamento da homoafetividade negra, demonstrando como as representações ainda não contemplam complexidades na identidade negra, limitada a um espaço de diversidade.

ABSTRACT Objective: This study aimed to compare the nasopharynx and oropharynx airway dimensions of Caucasians, Blacks, Japanese, Japanese Brazilians, and Black Caucasians. Methods: A sample of 216 lateral radiographs of untreated young Brazilian subjects (mean age of 12.94 years; SD 0.88) were divided into five groups: Black Caucasian, Black, Caucasian, Japanese, and Japanese Brazilian. Lateral radiographs were used to measure the oropharynx (from the midpoint on the soft palate to the closest point on the anterior pharyngeal wall) and the nasopharynx (from the intersection of the posterior border of the tongue and the inferior border of the mandible to the closest point on the posterior pharyngeal wall). Analyses of variance (ANOVA) and Tukey’s test were performed (p< 0.05). Results: The linear dimension of the oropharynx was similar among the different ethnic groups. Caucasian individuals presented a significantly greater linear dimension of the nasopharynx than Black Caucasian and Black individuals. Conclusions: All the groups had similar buccopharyngeal values. However, Caucasian individuals had significantly higher values when compared to Black Caucasians and Black individuals.
Superimposition of virtual models using palatal rugae and maximum habitual intercuspation

Published: May 2024

ABSTRACT Introduction: The superimposition of 3 dimensions (3D) digital models has been increasingly used for evaluating dental changes resulting from orthodontic treatment, and different superimposition techniques have been described. Although the maxilla has areas with greater stability for superimposition, such as the palatal rugae, there is still no reliable method for superimposing models of the lower arch. Objective: Therefore, this article aims to describe a technique for superimposing virtual models. Methods: To evaluate pre- and post-orthodontic treatment changes, the Geomagic Qualify 2013 software (3D Systems®, Rock Hill, South Carolina, USA) was used, with reference points in the maxilla, including the rugae and a reference area in the palate and midpalatal raphe. The lower arch was superimposed using the maximum habitual intercuspation (MHI) model as reference. Results and Conclusion: 3D models superimposition using palatal rugae and MHI occlusion seems to offer satisfactory results in the interpretation of clinical changes at different follow-up moments in terms of development and/or orthodontic treatment.

RESUMO Objetivo Verificar o repertório lexical de crianças falantes do português brasileiro aos 24 e 30 meses e a associação entre a quantidade de palavras faladas e as variáveis: nível socioeconômico, escolaridade dos pais, presença de irmãos no convívio familiar, frequentar ou não escola e uso exacerbado de tablets e celulares pelas crianças. Método 30 pais de crianças com 24 meses, residentes no estado de São Paulo participaram do estudo. Por meio de plataformas de videoconferência eles foram submetidos à anamnese fonoaudiológica, entrevista com o serviço social e preencheram o “Inventário MacArthur de Desenvolvimento Comunicativo - Primeiras Palavras e Gestos”, quando seus filhos tinham 24 e 30 meses. Foi aplicada estatística indutiva inferencial, quantitativa e qualitativa. Resultados A mediana das palavras emitidas foi de 283 aos 24 meses e 401 aos 30 meses, indicando aumento em torno de 118 palavras após seis meses. A criança estar frequentando ambiente escolar apresentou relação significativa com o aumento do vocabulário. Conclusão O estudo reforça o crescimento do vocabulário conforme o avanço da idade e corrobora o fato de as crianças com 24 meses já possuírem um repertório maior que 50 palavras. Aqueles que frequentam escola diariamente produzem pelo menos 70 palavras a mais dos que não frequentam.

Resumo Introdução O ultrassom utilizado em terapias diatérmicas visa atingir temperaturas entre 40 e 45 °C, sabendo-se que temperaturas acima de 45 °C podem causar necrose tecidual e queimaduras. Muitas pesquisas têm sido realizadas para estudar o efeito do ultrassom terapêutico na presença de implantes metálicos, utilizando phantoms (corpos de prova) e animais in vivo e ex vivo. Na maioria dessas pesquisas, o cabeçote ultrassônico está fixo em uma área, enquanto que na prática clínica recomenda-se que ele seja movimentado para evitar eventuais sobreaquecimentos locais. Objetivo Analisar o campo térmico na interface músculo-osso em phantoms na presença ou ausência de implantes metálicos após a aplicação do ultrassom terapêutico. Métodos Foram elaborados phantoms compostos de camadas simuladoras de gordura e músculo e de uma camada de osso de costela bovina, sendo esta com e sem implante metálico de titânio. O experimento envolveu diferentes intensidades (1.0, 1.5 e 2.0 W/cm2) e tempos de exposição (5 e 10 minutos) comuns em clínica, com varredura linear do cabeçote. Resultados Os experimentos indicaram que a interface músculo/implante aqueceu menos do que a interface músculo/osso, especialmente nas intensidades de 1.5 e 2.0 W/cm2, após 5 e 10 minutos de tratamento. Conclusão Os resultados obtidos apontam para a possibilidade de utilização do ultrassom terapêutico em pacientes com implantes metálicos, incentivando pesquisas futuras para desenvolver protocolos baseados em evidências e recomendações seguras na fisioterapia.

Abstract Introduction The severity of acute respiratory distress syndrome (ARDS) caused by COVID-19 can vary and be influenced by comorbidities. The position is a treatment strategy for critically ill patients; however, it is unclear what the physiological response is and which patients benefit. Objective To determine whether the prone position (PP) and the length of stay in the intensive care unit (ICU) are associated with the time of orotracheal intubation (OTI) and with the death rate in patients on mechanical ventilation with moderate to severe ARDS. Methods An observational, longitudinal, retrospective study was carried out in a tertiary public hospital in the city of São Paulo. Data were collected from the medical records of all patients diagnosed with COVID-19, with a positive PCR, admitted to the ICU and intubated, from April 2020 to July 2021. Pearson's chi-square and Fischer's exact tests were used to compare sample data, and distributions in the two groups were compared using the Mann-Whitney test. Results There was no statistically significant difference for ICU length of stay, OTI time and death rate between patients who were prone versus non-prone [13 (4.0 – 23.0) vs. 13.5 (7.2 – 17.0), p = 0.453; 12 (3.0 – 13.0) vs. 10 (6.0 -15.5), p = 0.772; 71 vs. 68%, p = 0.817, respectively]. Conclusion This study did not demonstrate an association between PP and days of OTI, days of hospitalization and mortality in patients with severe hypoxemia.
