Authors: Voronina E. V. , Frolova N. V. , Balandina A. V.
Published: September 2023

The article investigates the content of benz(a)pyrene in the soil and leaves of the medicinal plant Plantago magorL. growing in the Perm Territory at different distances from a major highway. The authors found an increase in the concentration of benz(a)pyrene in the soil and in the leaves of Plantago major L. during three years from 2019 to 2021. This is associated with the increase in traffic intensity along the Perm-Ilyinsky highway. The article shows a tendency to decrease the concentration of benz(a)pyrene in all soil samples and leaves of the plant has as distance from the highway. The authors give recommendations regarding the harvesting of leaves of the medicinal plant Plantago major L. in Ilyinsky district, which is advisable to grow at a distance of at least 500 m from the highway.
Features of the self-restoration of the oil-contaminated peat-bog soil – a field study
Authors: Chugunova Marina , Bakina Lyudmila , Gerasimov Alexander
Published: September 2023

The features of self-restoration processes of the oligotrophic peat-bog soil disturbed by crude oil pollution were studied. Soil contamination was carried out in field long-term experience. The key soil self-recovery indicators were: (1) the rate of carbon dioxide emission by the soil, which quantitatively characterizes the mineralization of petroleum hydrocarbons by microorganisms; (2) content of petroleum products. The microorganisms of the studied soil were characterized by low resistance to the toxic effects of oil: during the first three years of the experiment, the respiration of oil-contaminated soils was significantly lower than in pure soil. Restoration of microbial respiration to the control level and its further intensive growth occurred after 4-5 years of the experiment only in soils with low oil doses: 0.3 and 0.6 l m-2. In time, this coincided with the maximum rate of oil decomposition, which indicates the microbial nature of its utilization. The respiration of soil with oil high doses (1.8 and 3.0 l m-2) remained significantly lower than in pure soil throughout the entire experiment. At the same time, the amount of oil products in these samples markedly decreased. Oil degradation in these variants could occur due to the activity of anaerobic bacteria or abiotic processes.

Published: September 2023

Diseases that occur in such a multifactorial system as animal husbandry are determined not only by internal factors of the body, for example, the composition of the microflora of the digestive system, but also by external factors, such as feed. The aim of the study was to analyze the similarity of the microbiota of silage fed to cows with the composition of the microflora of their rumen and milk using the NGS sequencing method. The experiment was carried out on one of the commercial farms of the Leningrad region. The bacterial community of the contents of rumen, milk and silage from perennial cereals and legumes was evaluated by NGS sequencing on the MiSeq platform (Illumina, Inc., USA) with primers for the V3-V4 region of the 16S rRNA gene. As a result of the study, 22 phylum of attributed microorganisms were found in the microflora of silage, 24 to 30 phylum of rumen, 18 phylum of milk. Similar taxa of microorganisms were identified in silage, rumen and milk, the main difference was noted in quantitative ratios (P≤0.05). For example, the amount of Firmicutes in silage was 52.9 ± 3.45%, in milk - 11.8 ± 0.78%. This suggests that there may be some relationship between the studied biotopes. Pathogenic microorganisms, including the causative agents of mastitis, were present in many samples. The genera Staphylococcus, Acinetobacter, Streptococcus and Fusobacterium were identified by us as the most represented (P≤0.05) in the composition of the milk microflora. Their content was 0.24±0.023, 1.8±1.23, 1.0±0.06 and 0.35±0.031%, respectively. Probably, the microflora of the rumen can influence the formation of the milk microbiota.

Authors: Galeeva Asiya , Mingazova Nafisa , Gilmanshin Iskander
Published: September 2023

Nowadays protection and sustainable management of biological resources is of particular importance. The most important area of hydrobiological research is the assessment of the bioresource potential of aquatic ecosystems (Alimov et al., 2005). Phytoplankton is the basis of life and the most important component of the bioresource base in the aquatic ecosystem. Phytoplankton indicators (primarily abundance and biomass) are widely used to assess the bioresource potential of lakes due to its position as an autotrophic producer at the base of the ecological pyramid of the lake ecosystem (Bulion, 2005, 2019; Alimov, 1989, 2000; Alimov et al., 2005). Our study is aimed to research phytoplankton indicators to assess the bioresource potential of Kazan city’s lake ecosystems (Volga region, Russia).
The effect of sprinkler irrigation on the soil
Authors: Bocharnikov Viktor , Kozinskaya Olga , Denisova Maria , Bocharnikova Olesya , Repenko Tatiana
Published: September 2023

The article presents the results of research on the effect of sprinkling on the structural and aggregate composition of soil and its density. The high quality of sprinkling irrigation is achieved with uniform distribution of rain over the area, acceptable intensity with drop diameter and impact force, at which plants and soil structure are not damaged, puddles and surface runoff are not formed. For complete absorption of water into the soil and preservation of soil structure the rain of low intensity, with small drops is required. When applying sprinkling it is necessary to take into account the granulometric composition of the soil, slope, classification of the cultivated crop to coordinate it with the permissible intensity of rain. Erosion control measures should be applied only in a complex, as some of them cannot be replaced by any other. The system of erosion control measures should be properly combined and adapted to the forms of the land surface and local soil and climatic conditions and to develop measures to minimize the negative impact of irrigation on the soil.

Published: September 2023

The aim of the study was to study the effect of different concentrations of glyphosate on meat productivity and differential expression of genes for immunity and broiler productivity. Broilers were divided into groups: Control I, who received a diet without the introduction of glyphosate, Experimental II, who received a diet with the addition of glyphosate at a dose of 10 mg/kg of feed (0.5 MPC for food); Experimental III, who received a diet with the addition of glyphosate at a dose of 20 mg/kg of feed (1 MPC); Experimental IV, who received a diet with the addition of glyphosate at a dose of 100 mg/kg of feed (5 MPC). Transcriptome analysis was performed by RNA-seq on the Illumina Miseq platform, using the TruSeq Stranded mRNA kit (Illumina, USA). In the 22-28-day period of broiler rearing, a decrease in live weight gain (83 g less) was observed in Experimental group III compared to Control I (P≤0.05). It has been shown that glyphosate at the level of 1 and 5 MPC for food causes activation (P≤0.05) of the proinflammatory response genes (IL15, IL1B, IL34, IL22) and apoptosis (Casp1, Casp2, Casp6, Casp7, Casp8, Casp9) up to 31.1 times, which probably leads to the redistribution of nutrients in in the body towards the immune system, reducing the functions of absorption in the intestine. In parallel, there is an inhibition (P≤0.05) of the expression of genes that have a direct effect on growth and development, which ultimately leads to a decrease in poultry meat productivity. Exposure to glyphosate is an important but unaccounted-for risk factor for reducing meat productivity in birds, acting through a change in gene expression.

Published: September 2023

People associate existing fast food establishments not only with hamburgers and french fries, but also with nuggets, especially those enterprises that focus on the production of chicken products. With the classic processing of deep-fried nuggets, there is a rather large loss of product mass, and when using bad oil, the taste of the product is lost. Therefore, it is necessary to consider other types of heat treatment of this product to reduce production costs. The authors of the article conducted an experiment on alternative processing of nuggets in such equipment as a combi steamer and oven. The purpose of the experiment is to establish the weight loss of the product when using these types of heat treatment and to conduct an organoleptic evaluation of the resulting product. Raw materials were used from the manufacturer Meat Master LLC. The study was carried out according to 2 approved technologies on different equipment. The total weight loss of nuggets during processing in a combi steamer averaged 18%, and in an oven 13%. At the same time, processing in a combi steamer, in comparison with an oven, made it possible to better preserve the organoleptic properties of the nuggets. Also, thanks to the experiment, it was revealed that it takes time to bring the nuggets to culinary readiness, since during the experiment, the internal temperature of the product was recorded at intervals of 30 seconds. The product was prepared not by time, but by reaching a temperature in the depth of the product up to 800C. It was found that the average cooking time for nuggets in a combi oven is 6 minutes, and in an oven about 10 minutes. The results were the achievement of the goal of the experiment and the solution of related problems. The simulated cooking model made it possible to identify the time to bring to culinary readiness, the mass of losses and the organoleptic properties of nuggets cooked in a combi steamer and oven.

Ecological composition of communities of herpetobiont insects of the Botanical Garden of Volgograd Pedagogical University
Authors: Tokareva Tatyana
Published: September 2023

The species diversity of the herpetobiont complex in the biocenosis of the botanical garden is considered, the percentage of ground insects by the method of nutrition in the artificial ecosystem is analyzed, measures to attract beneficial insects to the territory of the botanical garden are proposed. The purpose of the work: to study a group of coleoptera insects from the herpetobiont complex on the territory of the botanical garden. The method of Barber pitfall traps was used to study coleoptera herpetobionts. The collected insects were recorded and stored for further processing and determination in the laboratory conditions. The entomocomplex of herpetobionts of the botanical garden consists of 15 species from 5 families. The most numerous are the Carabidae, the dominant species are Calathus ambiguus and Cicindela campestris). The subdominant species is Harpalus rufipes, the usual species are Calathus distinguendus, Silpha obscura, Poecilus versicolor. Rare species are Dorcus parallelipipedus, Crypticus quisquilius, Cymindis miliaris. The monotony and species poverty of the Botanical Garden ecosystem is determined by a special complex system of agrotechnical measures, the use of chemicals to exterminate insect pests, and the intensity of anthropogenic pressure. All this leads to instability and variability of the ecosystem. These findings confirm the thesis that overdomination is characteristic of unstable communities with disturbed equilibrium. As a result, there is an increase in insect pests of plants. The study of ground insects by the mode of nutrition revealed 4 groups: zoophages, phytophages, mixophages, necrophages. Zoophages, in particular various species of Carabidae, are the most widespread (66.7%). This is due to the abundance of small invertebrates, the nature of vegetation, the level of humidity in the botanical garden. In order to increase the diversity of the species composition of beneficial insects, it is necessary to create favorable living conditions for them: to increase the food base, to create shelters. The creation of a food reserve is solved by planting mixborders.

The forest is one of the complex terrestrial ecosystems with landscape-geographic variability. The problem of anthropogenic influence on the environment in general and forest ecosystems in particular is steadily growing. The cause of pollution of all environments with the products of technogenesis, a decrease in biodiversity, a decrease in vegetation cover is most often human activity. The increasing anthropogenic impact on forest ecosystems over the years causes a decrease in their biological resistance and can lead to degradation and even complete destruction. The work studies forest ecosystems of the Kabardino-Balkarian Republic. The main forestforming rocks of the republic were identified. The age structure of the main forest-forming species has been determined. An analysis of the dynamics of the forest area by completeness, bonite classes was carried out.

Published: September 2023

Plant-based milks and fermented plant-based milk products are gaining popularity but may not possess the same physicochemical characteristics as the traditional fermented dairy products. The different chemical composition of plant-based milk affects the physicochemical and consumer acceptability of fermented plant-based milk. To compare their characteristics to the traditional dairy yoghurt and consumer acceptability, different fermented plant-based milk products were prepared as well as their two-component mixtures and their physicochemical and consumer acceptability evaluated. The single component fermented plant-based milk sample (soy milk) did not vary in terms of physicochemical parameters with respect to the traditional fermented dairy product, yoghurt. The physicochemical parameters including pH, water holding capacity, syneresis improved when the milk samples were composited and are comparable to the traditional fermented dairy product (yogurt). The results indicated that the use of two-component plant-based milk for fermentation provides the best nutritional and energy values for consumers rather than using just one component. Also, the high consumer acceptability for fermented plant-based milk was demonstrated from the findings.

Authors: Wright F. E. , Womble Nolan E. , Williams John , Cone John , Ransom John , Read Raymond C.
Published: September 2023

Determination of colloid osmotic pressure (COP), arterial blood gases (ABG) and weight were made in 25 consecutive patients undergoing cardiopulmonary bypass (CPB) with hemodilution. COP measurements were made prior to CPB, at 30 minute intervals during perfusion, and at 6, 12, 24 and 48 hours following CPB. Arterial blood gases were measured at 6, 12, 24 and 48 hours post-operatively. COP decreased abruptly with the initiation of bypass from 25.4 ± 3.4 mmHg to 16.8 ± 4.6 mmHg (p < 0.05) and remained at this level throughout the duration of bypass. All COPs returned to baseline levels, 23.6 ± 4.1 mmHg, 48 hours after surgery. Maximum decrease in COP was compared to the increase in calculated alveolar-arterial O2 gradient at 6, 12, 24 and 48 hours post-operative, and no significant correlation could be found. Similarly, the decrease in COP did not correlate with the weight gain present at 24 and 48 hours. COP is significantly altered by CPB and undoubtedly results in changes in fluid compartment dynamics. However, changes in COP do not seem to play a role in ventilatory problems following CPB in the routine patient.

Published: September 2023

This study compares the management of heparin and protamine administration during cardiopulmonary bypass by a protocol assuming a constant heparin degradation rate with management by an activated coagulation time dose-response method.

The charts of 648 adult patients operated on between January 1975 and December 31, 1980, were reviewed. In Group I patients, heparin was administered at a dosage of 2.5 mg/kg of body weight and supplemented by 50% of the loading dose at 2 hours and 25% each hour thereafter. Protamine was administered on a 1:1 basis according to an assumed heparin degradation rate of 0.4% per minute. In Group II patients, heparin and protamine doses were based upon activated coagulation time dose-response curves.

Data extracted from the charts included blood loss and replacement data, heparin and protamine doses, and coagulation profiles. The data from the two groups were compared and analyzed.

Group II patients received more heparin, but less protamine, had more complete heparin reversal, less post-operative bleeding, and required less blood or blood product replacement.
Gaseous Emboli Removal Efficiency in Arterial Screen Filters: A Comparative Study
Authors: Massimino R. J. , Gough J. D. , Stearns G. T. , Martin J.
Published: September 2023

Seven commercially available arterial filters were evaluated for their effectiveness in removing gaseous emboli produced by various sources. All filters were of the screen type and ranged from 20–40 micron pore size.

The first phase of the study consisted of an appraisal of carbon dioxide flushing to facilitate priming. Two filters of each type were used. The first filter was primed without a carbon dioxide flush. The second filter was flushed with carbon dioxide.

Immediately after priming, microemboli were monitored distal to the filters for 10 minutes at 6 L/Min.

In the second phase each filter’s capability of removing gaseous emboli when used in conjunction with a bubble oxygenator was evaluated. Microemboli were alternately monitored pre and post filter at fluid flow rates ranging from I to 6 L/Min. At each liter of fluid flow rate the gas:fluid ratio was varied from 1:1 to 3:1.

In the third phase of the study, the efficacy of each filter in removing varying amounts of room air was evaluated. Boluses of room air ranging from 1 to 50 cc. were injected proximal to the filter with microembolism monitoring distally. Injections were made at flow rates ranging from 1 to 6 L/Min.

Although carbon dioxide flushing does facilitate priming the filters, it does not reduce microemboli counts distally. Gaseous emboli removal rates ranged from 69.6 to 100% when used in conjunction with a bubble oxygenator. Air emboli activity distal to the filter after air injections ranged from 0 to 91,000 counts/L of fluid flow.

Authors: Riley Jeffrey B. , Heinemann Stanley O. , Cavanaugh D. Susan
Published: September 2023

A technique to give relevance to results of oxygen transfer calculation during total cardiopulmonary bypass is presented.

An accurate calculation scheme to quantitate total blood oxygen transfer is outlined. Clinical relevance is given to the oxygen transfer calculation result by reporting the value as a percent of an expected oxygen transfer rate. An expected oxygen transfer value is predicted from large population metabolic rate study results employing patient sex, age, body surface area, and temperature.

Calculating the percent of expected oxygen consumption value will benefit the perfusionist by increasing the validity of CPB management decisions. The calculation of actual oxygen consumption will aid the perfusionist in selecting an appropriate artificial oxygenator ventilation rate and patient blood flow.
A New Method for the Conservation of Platelet Concentration During Extracorporeal Circulation
Authors: Jallad Munier S. , Winn Brad A. , Lein Timothy A.
Published: September 2023

Pluronic F-68, a non-ionic polyol, was investigated for its effect on platelet conservation, platelet function, release reaction, and red blood cell hemolysis during cardiopulmonary bypass (CPB). Three groups of ten dogs each underwent CPB utilizing both normothermia and hypothermia. The control group (bubble oxygenator) did not receive any Pluronic F-68. Experimental group I (bubble oxygenator) and group II (membrane oxygenator) received 2 mg of Pluronic F-68 per milliliter of priming fluid.

After 10 minutes of normothermic CPB, the platelet concentration decreased significantly by 48%. The platelet concentration in group I significantly decreased by 38%, and in group II the decrease was a non-significant 8%. There was also an associated increase in the plasma concentration thromboxane B2 and platelet factor 4 in both the control group and group I. A significant increase in free plasma hemoglobin was observed in the control group. The increase in group I and II was not significant.

During hypothermia (20°C), a significant change in platelets, thromboxane B2, and platelet factor 4 was observed in all groups. After re-establishing normothermia, platelet concentration remained significantly low at 48% in the control group, whereas the platelet concentration in group I increased to 80%, a decrease of 20%, and in group II increased to 92%, a decrease of 8%. Free plasma hemoglobin, platelet factor 4 and thromboxane B2 remained significantly elevated in the control and group I. There was no significant elevation in platelet factor 4, free plasma hemoglobin, and thromboxane B2 in group III.

Pluronic F-68, an emulsifying agent, has therefore been shown to be effective in platelet preservation during CPB.
Streptokinase Infusion in the Treatment of Acute Myocardial Infarction: A Review
Authors: Woodside Mary Ellen , Dearing James P.
Published: September 2023

Recent studies indicate that Streptokinase therapy early in Acute Myocardial Infarction can successfully produce coronary thrombolysis in approximately 80% of such patients. Reperfusion is frequently accompanied by relief of chest pain and normalization of ST segments. Cineangiography has shown myocardial salvage of the infarct region, improved LV function, and lowered mortality rates. The untoward effects of Streptokinase treatment appear to be manageable and the benefits of recanalization with Streptokinase outweigh the risks and side effects involved.

Authors: Evans Nelson , Haselton Wilfred , Rubis Lorraine J. , Harrah John D.
Published: September 2023

The perarterial intra-aortic balloon (PAIAB) insertion technique has been shown at our institution to significantly reduce ischemic complications common to intra-aortic balloon (lAB) use. This technique is a modification of the percutaneous insertion method and utilizes the same introducer system. The common femoral artery is exposed and the balloon inserted under direct visualization.

Forty-five consecutive patients underwent attempted (PAIAB) insertion. Successful passage on the first attempt was accomplished in 39 patients (87%) and in 42 patients (93%) when the contralateral femoral artery was employed. In three patients (7%), the balloon could not be passed via either femoral artery. In 36 patients, the balloons were inserted preoperatively for support of high risk left main or left main equivalent coronary artery disease or poor left ventricular function prior to anesthetic induction. Twenty-nine intra-aortic balloons were removed immediately post perfusion with no incidence of thrombus on the balloon or catheter. Thrombus was present on four of 13 intra-aortic balloons (31%) left in from one to seven days.

Balloon removal was accomplished in the operating room under direct vision which allows for assessment of the puncture site, thrombus removal, and arterial repair. Had the artery not been exposed, the four patients with thrombus present could have suffered limb ischemia.

Published: September 2023

A 58 year-old male underwent urgent aorta-coronary bypass surgery for unstable angina. A 40cc. percutaneous intra-aortic balloon was inserted pre-operatively, resulting in good augmentation. No problems were observed in the Coronary Care Unit and the patient was stabilized.

Approximately 45 minutes post aorta-coronary bypass, diastolic augmentation drastically changed. During inspection of the balloon catheter, a Kelly clamp, partially occluding the catheter, was found. The Kelly clamp was removed and augmentation was resumed.

While preparing the patient for transport from the Operating Room to the Intensive Care Unit, augmentation by the Intra-aortic balloon pump was temporarily stopped. All attempts to resume augmentation were unsuccessful. Close visual inspection of the catheter showed 2 holes just proximal to the site of the Kelly clamp occlusion. It was later determined that these holes were made with a towel clamp. Effective repair of the catheter could not be made and the balloon was removed.

Concurrent Dialysis During Cardiopulmonary Bypass
Authors: Rohrer Charlene H. , Hartley Winkler Mary
Published: September 2023

A series of cardiac surgical patients with acute or chronic renal failure. who required renal dialysis during cardiopulmonary bypass (CPB) is presented. The mean decrease in the creatinine levels during CPB with dialysis was l.7 mg/dl. The pre-bypass range was 3.0 - 6.8 mg/dl and the post-bypass range was 1.9 - 3.9 mg/dl. All patients were successfully weaned from cardiopulmonary bypass. A significant decrease in the Blood Urea Nitrogen (BUN) and creatinine levels were observed in all patients. Metabolic and electrolyte derangements were corrected when encountered. Dialysis was not required in the immediate postoperative period for any of the patients in this series. The hemodynamic instability often encountered with dialysis was eliminated by utilizing concurrent dialysis during CPB. This proved to be a safe and effective method for treatment of the cardiac surgical patient in renal failure.

Published: September 2023

L’étude de la suture méso-palatine (SMP) présente un intérêt majeur dans le traitement orthodontique des patients présentant une endomaxillie. Sa classification selon Angieleri et al. et grâce à l’imagerie en trois dimensions pourrait nous aider pour choisir la bonne technique de disjonction : chirurgicale ou orthopédique. Nous avons réalisé une étude rétrospective bicentrique avec une lecture en double aveugle sur des images de cone-beam obtenues entre 2017 et 2022. L’inclusion de 57 patients de 11 à 15 ans nous a permis de montrer que la SMP a plus tendance à être fermée chez les 14 15 ans que chez les 11 13 ans. Cependant des cas avec une SMP ouverte sont retrouvés dans toutes les tranches d’âge. Le sexe ne semble pas être un facteur déterminant sur la SMP.

La SMP étant parfois ouverte tardivement un cone-beam avant disjonction permettrait de choisir de manière individuelle la technique la plus appropriée.

Résultats : après l’examen de 465 publications, 4 études (3 cas-témoins et 1 étude transversale publiées entre 2018 et 2021) répondaient aux critères d’inclusion et suivaient des protocoles hétérogènes, difficilement comparables, comportant des biais de niveaux variables. Les principaux résultats étaient les suivants : les enfants TDAH étaient significativement plus susceptibles de développer des malocclusions, indépendamment de leur âge, du recours à une tétine et d’une ventilation orale. La prévalence des rotations dentaires et des occlusions inversées est significativement plus élevée chez les enfants TDAH. De plus, la dimension antérieure du palais était significativement plus étroite. Les enfants TDAH présentaient des analyses céphalométriques similaires, excepté pour les voies aériennes supérieures qui étaient globalement plus étroites. Également, les enfants TDAH présentaient plus de parafonctions (bruxisme, habitudes de succion nonnutritives) et une prévalence plus importante de ventilation orale. Finalement, un sommeil plus agité, la présence de ronflement et la sensation de fatigue dès le matin étaient significativement rapportés chez les enfants TDAH en comparaison à des enfants non-TDAH. Conclusion : il semblerait qu’un lien existe réellement entre malocclusions et TDAH, autour d’un contexte dysmorpho-dysfonctionnel plus global.

Satisfaction du patient et qualité de vie après une chirurgie orthognathique primaire : une revue systématique
Authors: Martinez Mallaury , Fawaz Paul , Vande Vannet Bart
Published: September 2023

Objectifs : la chirurgie orthognathique permet une amélioration des fonctions masticatoires, phonétiques, respiratoires et sociales ainsi qu’une harmonisation du sourire et du visage quand l’orthodontie conventionnelle à elle seule est incapable de le faire. Ces traitements améliorent non seulement l’occlusion, mais aussi la confiance en soi, l’esthétique et la qualité de vie du patient. L’objectif de cette revue systématique est d’évaluer l’impact du protocole de chirurgie de première intention (SFA : Surgery first approach) sur la qualité de vie du patient et sa différence avec le protocole de traitement orthodontico-chirurgical conventionnel (COST : conventional orthodontic-surgical treatment).

Matériels et méthodes : la base de données MEDLINE via PUBMED a été consultée depuis janvier 2012 jusqu’en juin 2023. Après sélection des titres et des résumés, les études portant sur la qualité de vie des patients traités par chirurgie de première intention ont été incluses. La qualité méthodologique des études a été évaluée à l’aide du Cochrane Handbook for Systematic Reviews of Interventions et de l’échelle de Newcastle-Ottawa.

Résultats : uniquement les études cohorte et les essais contrôlés randomisés pouvaient être inclus dans notre étude. 7 études ont été incluses. L’essai contrôlé randomisé a été classé comme présentant un risque élevé de biais. Pour les études de cohorte, 3 ont été jugées comme ayant un faible risque de biais et les 3 autres avaient un risque de biais peu clair ou élevé. Les études ont toutes montré une amélioration de la qualité de vie des patients après un traitement orthodontico-chirurgical, qu’il s’agisse du protocole SFA ou COST. Des différences ont été constatées au cours du traitement. Les patients recevant le protocole SFA ont montré une amélioration immédiate de la qualité de vie au début du traitement. Cependant, aucune différence significative n’a été trouvée entre les deux protocoles, que ce soit avant ou après le traitement.

Conclusion : bien qu’il n’y ait pas eu de différence significative entre le groupe SFA et le groupe COST avant et après le traitement, le protocole SFA a permis d’éviter une détérioration de la qualité de vie pendant le traitement en inhibant l’aggravation de décalage squelettique par absence de décompensation orthodontiquepréalable. Les conséquences sont une plus grande satisfaction et motivation des patients pour la poursuite de leur traitement orthodontique, ce qui peut guider l’orthodontiste à choisir cette approche plutôt que l’approche conventionnelle.

Apport des ancrages vissés dans les avulsions mono maxillaires des secondes prémolaires maxillaires en technique linguale : à propos d’un cas
Authors: Queralto Isabel , Bouallègue Imen
Published: September 2023

Introduction : le recours aux extractions mono maxillaires de prémolaires peut constituer chez les patients adultes présentant une malocclusion de classe 2 une solution thérapeutique de choix lorsqu’il existe peu ou pas de dysharmonie dents-arcade d’origine mandibulaire. Les avulsions des deuxièmes prémolaires sont souvent à privilégier à celles des premières prémolaires, pour des raisons tant occlusales qu’esthétiques. Cependant, elles se heurtent en technique linguale, notamment du fait de la plus grande difficulté d’ancrage, à de nombreux effets parasites. Le recours à des ancrages vissés dans la zone palatine s’avère être un auxiliaire idéal.

Matériel et méthode : le but de cet article est de présenter grâce à un cas clinique, un dispositif d’ancrage palatin dans la région palatine médiane : le Bitripod Anchor Plate (BAP). Puis, face à une intolérance au niveau de ce site, une alternative en zone palatine paramédiane : le Palatal Retractor Device (PRD).

Discussion : les avantages et inconvénients de ces ancrages sont ensuite comparés entre eux et à d’autres alternatives.

Conclusion : en technique linguale, il est important d’utiliser l’ancrage adapté selon les mouvements nécessaires pour aboutir aux objectifs du plan de traitement. Pour cela, le recours aux ancrages palatins fait partie de nos jours du Gold Standard. La maîtrise de leurs propriétés permet de s’adapter à la situation clinique de chaque patient pour s’assurer d’une pose sécurisée.
Caesarean Scar Pregnancy: Single Dose of Intrasac Ultrasound-Guided

The purpose of the study was to assess the efficacy of local
ultrasound-guided methotrexate injection in patients with caesarean section scar
pregnancy, to chart the course of beta-human chorionic gonadotropin levels (HCG)
after treatment, and to see if HCG levels are correlated with clinical
presentation.

Between May 2018 and January 2021, data were collected
retrospectively from the Early Pregnancy Unit of a tertiary hospital.

Our clinic assessed 20 patients; one disputed terminating the
pregnancy and was not included in the research. The remaining 19 patients, with
a median age of 34 years, received intragestational sac methotrexate injection
under ultrasound guidance. 7w3d was the median gestational age. These women had
one to four previous caesarean sections, with a mean of 1.60±9. Patients
with caesarean scar pregnancy most typically presented with spotting
(42.1%), whereas 26.3% were asymptomatic. Except in cases of
pain, the symptomatic women’s HCG levels were lower than in the
non-symptomatic women. The level of HCG in patients with pain was approximately
double that of non-pain patients (p=0.2557). In our series,
intragestational sac methotrexate injection was effective in 17/19
women, or 89.5% (95%CI: 75.7-100%). HCG levels were
undetectable in 97.6±30 days on average (minimum: 42 days, maximum: 147
days).

Caesarean scar pregnancy is a rare possibly fatal condition
with no consensus on the optimal treatment. An experienced Early Pregnancy Unit
member performing local methotrexate injections under ultrasound guidance is a
feasible and successful strategy in clinically stable patients.

Background Despite advances in understanding and reducing the risk of endoscopic procedures, there is little consideration of the safety of the wider endoscopy service. Patient safety incidents (PSIs) still occur. We sought to identify nonprocedural PSIs (nPSIs) and their causative factors from a human factors perspective and generate ideas for safety improvement.

Methods Endoscopy-specific PSI reports were extracted from the National Reporting and Learning System (NRLS). A retrospective, cross-sectional human factors analysis of data was performed. Two independent researchers coded data using a hybrid thematic analysis approach. The Human Factors Analysis and Classification System (HFACS) was used to code contributory factors. Analysis informed creation of driver diagrams and key recommendations for safety improvement in endoscopy.

Results From 2017 to 2019, 1181 endoscopy-specific PSIs of significant harm were reported across England and Wales, with 539 (45.6%) being nPSIs. Five categories accounted for over 80% of all incidents, with “follow-up and surveillance” being the largest (23.4% of all nPSIs). From the free-text incident reports, 487 human factors codes were identified. Decision-based errors were the most common act prior to PSI occurrence. Other frequent preconditions to incidents were focused on environmental factors, particularly overwhelmed resources, patient factors, and ineffective team communication. Lack of staffing, standard operating procedures, effective systems, and clinical pathways were also contributory. Seven key recommendations for improving safety have been made in response to our findings.

Conclusions This was the first national-level human factors analysis of endoscopy-specific PSIs. This work will inform safety improvement strategies and should empower individual services to review their approach to safety.
