Цель исследования — проанализировать обусловленность изменения положения третьих моляров (ТМ) с возрастом. Проанализированы более 3000 ортопантомограмм (ОПТГ) челюстей пациентов в возрасте от 7 до 25 лет с различными аномалиями зубочелюстной системы: скученное положение зубов, сужение зубных рядов, мезиальная и дистальная окклюзия. Изучали стадии формирования ТМ, угол их наклона и их расположение относительно биссектрисы гониального угла и контрфорсов верхней и нижней челюсти. Контрфорсы на верхней челюсти располагаются вертикально и не препятствуют правильному прорезыванию зубов. При расстоянии от контрфорса до зачатка нижнего ТМ более 2,0 мм и угле наклона более 70° возможно его прорезывание, а при отсутствии расстояния и угле наклона менее 70° целесообразно удалять эти зубы (патент № 2778775, действ. с 28.12.2020). Расстояние от коронок нижних ТМ относительно биссектрисы гониального угла и угол наклона моляров с возрастом уменьшаются. Анализ корреляционных связей параметров ОТПГ челюстей показал значимую взаимосвязь таких показателей как возраст, положение и угол наклона ТМ, величина гониального угла и стадия формирования корней моляров.
The aim of the study is to analyze the conditionality of changes in the position of the third molars (TM) with age. . More than 3000 orthopantomograms (OPTG) of the jaws of patients aged 7 to 25 years with various anomalies of the maxillary system were analyzed: crowded position of teeth, narrowing of dentition, mesial and distal occlusion. The stages of TM formation, their angle of inclination and their location relative to the bisector of the gonial angle and buttresses of the upper and lower jaws were studied. . Buttresses on the upper jaw are arranged vertically and do not prevent proper teething. If the distance from the buttress to the rudiment of the lower TM is more than 2.0 mm and the angle of inclination is more than 70°, its eruption is possible, and if there is no distance and the angle of inclination is less than 70°, it is advisable to remove these teeth (patent No. 2778775, effective from 12.28.2020). The distance from the crowns of the lower TM relative to the bisector of the gonial angle and the angle of inclination of the molars decrease with age. . The analysis of correlations between the OPTG parameters of the jaw showed a significant relationship between such indicators as age, the position of the third molars, the angle of inclination of the third molars, the value of the gonial angle and the stage of formation of molar roots.

Цель работы — оценка качества лечебных мероприятий, связанных с реставрационным лечением дефектов твердых тканей боковых зубов с точки зрения выявления ятрогенных причин первичной травматической окклюзии. Обследовано 306 человек с физиологическими формами прикуса, из них выделены 4 группы в зависимости от наличия и этиологических причин (ятрогения, связанная с некорректным реставрационным лечением дефектов твердых тканей боковых зубов, влияние 3-х моляров и комбинация этих двух факторов) первичной окклюзионной травмы. Установлено, что только 45 (14,7%) человек не имели симптомов первичной травматической окклюзии, у всех остальных 261 (85,3%) обследованных были выявлены нарушения окклюзионного рельефа боковых зубов различного генеза. Не соответствовали требованиям 76,5% всех имеющихся пломб, в большинстве случаев по качеству моделировки окклюзионной поверхности, по контактному пункту, по наличию краевой щели. Это позволяет утверждать, что многие стоматологи при реставрации восстанавливают рельеф зуба без учета морфологии окклюзионной поверхности и корректного взаимоотношения с антагонистами. Выявлены наиболее частые симптомы первичной травматической окклюзии: фасетки стирания твердых тканей, трещины эмали, клиновидные дефекты, изменение десневого края и пародонтальные карманы, супраконтакты на рабочей или на балансирующей сторонах. Ятрогенные причины нарушений окклюзионного рельефа можно рассматривать не только как дефект оказания медицинской помощи, но и как потенциальную причину тяжелых стоматологических заболеваний в отдаленные сроки.
The aim of this study is to assess the quality of posterior teeth restorations in to identify the iatrogenic cause of primary traumatic occlusion. . 306 participants with physiological bite were examined. They were separated into 4 groups according to iatrogenic factors: unacceptable posterior restorations, 3-rd molar affection, combination of these factors. . Only 45 (14.7%) people did not have symptoms of primary traumatic occlusion, all the other examined (261 people, or 85.3%) had violations of occlusal relief of posterior teeth of various origins. It was found that 76.5% of fillings did not meet clinical requirements, in most cases due to poor representation of occlusal surface, contact point, presence of a marginal gap. It can be explained that many dentists do not pay attention to morphology of occlusal surface and correct relation with antagonists. The most common symptoms of primary traumatic occlusion were: hard tissue abrasion facets, enamel cracks, wedge-shaped defects, changes in the gingival margin and periodontal pockets, supracontacts on the working or balancing sides. . Authors considered that iatrogenic unacceptable occlusal relief should be interpreted not only as a mistake, but also as a potential cause of severe dental diseases in long term.

Ввиду высокой распространенности пародонтита поиск новых методов противомикробного воздействия остается актуальным. Цель работы — исследовать антибактериальную эффективность применения фотодинамической терапии с использованием аппарата Revixan® Dental LED Pro на тканях пародонта. Клиническая часть исследования проводилась у 20 пациентов с диагнозом «хронический пародонтит». Микробиологическое исследование включало анализ встречаемости и количественный анализ представителей грамположительной и грамотрицательной микрофлоры. Наибольшую роль в развитии пародонтита играют P. gingivalis, P. intermedia и F. nucleatum. Выявлено уменьшение частоты встречаемости P. gingivalis после проведения фотодинамической терапии на 5%. Отмечалось снижение количества пародонтопатогенов. Максимальное количество для микроорганизмов P. gingivalis, P. intermedia, F. nucleatum сократилось с 9,5·10 до 1·10, с 4·10 до 1·10, с 4·10 до 1·10 КОЕ/мл соответственно. Полученные данные свидетельствуют об антибактериальной эффективности воздействия фотодинамической терапии с использованием аппарата Revixan Dental LED Pro на содержимое пародонтальных карманов, что доказывает возможность замены местной антибактериальной терапии.

Уже на протяжении длительного времени в ортодонтии ведется разработка праймеров и бондов с улучшенными адгезивными свойствами для фиксации металлических брекетов к эмали зубов, что особенно важно при работе с боковыми зубами. Цель исследования — сравнение результатов прочности адгезии на сдвиг между отечественным адгезивом V поколения и зарубежного аналога в лабораторных условиях. Исследование проводили на 20 образцах удаленных моляров верхней и нижней челюсти, которые погружали в блоки из акриловой пластмассы. Все образцы были разделены на две группы: в I группе фиксацию металлических брекетов к эмали зубов проводили с применением отечественного набора «Компофикс (Орто)» (ВладМиВа, Россия), во II группе — с использованием зарубежного аналога Enlight (Ormco, США). В I группе показатели адгезии на сдвиг составили 13,21±1,11 МПа, а во II группе — 13,39±1,23 МПа. Среднее значение индекса адгезивных остатков на поверхности брекета в I группе было 18±3%, во II — 15±3%. Результаты исследования показали, что отечественная адгезивная система V поколения не уступает по своим свойствам зарубежному аналогу и рекомендована к использованию в клинической практике врача-ортодонта.
For a long time orthodontists has been developing primers and bonds with improved adhesive properties for fixing metal braces to the teeth enamel, which is especially important for lateral teeth. The aim of the study was to compare the results of the shear strength of adhesion between a domestic adhesive system of the V generation and a foreign analogue in laboratory conditions. . The study was carried out using 20 samples of extracted molars of the upper and lower jaws, which were immersed in blocks of acrylic plastic. All samples were divided into two groups: in the group I the fixation of metal braces to the teeth enamel was carried out using a domestic adhesive system Compofix (ortho) (VladMiVa, Russia); in the group II the fixation of metal braces to the teeth enamel was performed using a foreign analogue Enlight (Ormco, USA). . In the group I the value of shear adhesion was 13.21±1.11 MPa, while in the group II — 13.39±1.23 MPa. The average value of the adhesive remant index to the bracket surface was 18±3% in the group I and 15±3% in the group II. . The results of the study showed that the domestic adhesive system of the V generation is not inferior in its properties to a foreign analogue and is recommended for use in the clinical practice in orthodontics.

This study was conducted with a cross-sectional design to determine pediatric nurses' knowledge and practices related to pain management in children with cognitive impairment. The sample of the study consisted of 65 pediatric nurses working in two different hospitals in one city. After obtaining institutionals, ethics committee permissions, and written consent from participants, the data were collected using a ıntroductory characteristics form and a questionnaire to determine knowledge and practices regarding pain management in children with cognitive impairment. Descraiptive statistics and Chi-square tests were used for data analyses.
The majority of the pediatric nurses reported the parameters used to assess pain among children with cognitive impairment as facial expressions and behavioral responses. Only 16.9% of nurses evaluated pain using a scale. In terms of reducing the pain of children with cognitive impairment, 55.4%, 35.4% of nurses reported that they used nonpharmacological, pharmacological methods, respectively, and 9.2% no specific methods were used in the clinic where they worked. The commonly used nonpharmacological methods were distraction, massage, cold application, etc. A significant difference was found in the use of nonpharmacological methods with respect to gender and previous training on pain management (p

Çalışma, beslenmenin nutrigenetik ve nutrigenomik bakımından sporcularda oluşturduğu etkileri incelemek amacıyla yapılmıştır. İnternet veri tabanlarına kayıtlı alana özgü çalışmalar incelenmiş ve özetlenmiştir. Omiks teknolojilerinde yaşanan gelişmeler sonucunda bireyselleştirilmiş diyet yaklaşımları ve beslenme stratejileri, önemli uygulamalar hâline gelmiştir. Bu alanlardan biri olan sporda beslenme, sporcuların sağlıklarını korumak ve performanslarını artırmak için anahtar role sahip bir beslenme türüdür. Bu amaçla makro ve mikro besin maddeleri, sporcu beslenmesinde önemlidir.
Sporcu beslenmesi üzerinde etkili olabilecek içsel-dışsal birçok faktör bulunmaktadır. Bu faktörlerden biri olan genetik, sporcu beslenmesinde dikkate alınması gereken önemli bir husustur. Sportif performans, besin maddelerinin metabolizmadaki etkinliği ile bu maddelerinin insan genomundaki ekspresyon seviyesi ile ilgili bir durum olabilir. Bu amaçla nutrigenetik ve nutrigenomik kavramları, sporcu performansı açısından dikkate alınması gereken konulardır. Çalışmada, nutrigenetik ve nutrigenomik kavramlarının teorikte aynı ama içerikte bazı farklılıklara sahip olabildikleri sonucu görülmüştür.
Sonuç olarak, sportif performans yalnız besin maddelerinin sporcu genomundaki metabolizmal faaliyetleri ile ilgili bir durum olmayabilir. Sportif performansı etkileme gücüne sahip içsel-dışsal birçok faktör bulunmaktadır.

Aim. To enhance the outcomes of treating patients with acute non-occlusive mesenteric ischemia (focal) following colostomy, aiming to gain a better understanding of the prevalent risk factors for complications and exploring ways of their reduction.Materials and methods. A clinical case detailing the treatment of a patient with acute non-occlusive mesenteric ischemia amidst abdominal sepsis and stoma necrosis, compounded by inflammatory disease of the spinal cord membranes, is presented. Additionally, the clinical observation of a patient experiencing postoperative complications, including coronavirus infection and bilateral hydrothorax, is provided.Results. In a patient presenting severe coronary pathology alongside a nuanced clinical manifestation of mesenteric ischemia in the delayed phase, a surgical intervention involving intestinal tract resection and subsequent stoma removal was conducted. Regrettably, stoma necrosis ensued, necessitating reconstructive surgery. The patient’s initial critical state, compounded by the requirement for repeated surgical intervention, precipitated a swift progression of multiple organ failure, culminating in mortality. Conversely, another patient, postoperatively diagnosed with coronavirus infection and bilateral hydrothorax, exhibited amelioration in clinical status following administered treatment, ultimately warranting hospital discharge.Conclusions. Early diagnosis and timely surgical intervention contribute to improving the prognosis of treatment. Early postoperative complications and repeated surgical interventions significantly worsen the prognosis.

Published: December 2023

Objective:
Literature reviews are essential to the scientific process and allow clinician researchers to advance general knowledge. The purpose of this study was to evaluate if the artificial intelligence (AI) programs ChatGPT and Perplexity.AI can perform an orthopedic surgery literature review.

Materials and Methods:
Five different search topics of varying specificity within orthopedic surgery were chosen for each search arm to investigate. A consolidated list of unique articles for each search topic was recorded for the experimental AI search arms and compared with the results of the control arm of two independent reviewers. Articles in the experimental arms were examined by the two independent reviewers for relevancy and validity.

Results:
ChatGPT was able to identify a total of 61 unique articles. Four articles were not relevant to the search topic and 51 articles were deemed to be fraudulent, resulting in 6 valid articles. Perplexity.AI was able to identify a total of 43 unique articles. Nineteen were not relevant to the search topic but all articles were able to be verified, resulting in 24 valid articles. The control arm was able to identify 132 articles. Success rates for ChatGPT and Perplexity. AI were 4.6% (6 of 132) and 18.2% (24 of 132), respectively.

Conclusion:

The current iteration of ChatGPT cannot perform a reliable literature review, and Perplexity.AI is only able to perform a limited review of the medical literature. Any utilization of these open AI programs should be done with caution and human quality assurance to promote responsible use and avoid the risk of using fabricated search results. [

Influence of the impurity content on the density and viscosity of olive oily fluids
Authors: Vallesquino-Laguna P. , Tirado-Esquinas A. 
Published: December 2023

In this work, as a case study, the measurement of the density (ρ) and the dynamic viscosity (µ) of 12 different fluids (taken from a conventional oil mill) has been carried out. The variability of the samples processed shows that their impurity contents c (between 0.5-5.87%), together with the temperature t (which varied between 20-30 ºC), can affect the values of ρ and µ. However, this variation has been shown to be different depending on the case, being of the order of 1% for density or even more than 50% for dynamic viscosity. The fact that µ can be sensitive to the presence of impurities opens up a line of study that could be used to estimate such impuritiy content, in real time, by means of relatively simple methods.

Abstract
Our bodies are home to individual-specific microbial ecosystems that have recently been found to be modified by cancer immunotherapies. The interaction between the gut microbiome and islet autoimmunity leading to type I diabetes (T1D) is well described and highlights the microbiome contribution during the onset and T1D development in animals and humans. As cancer immunotherapies induce gut microbiome perturbations and immune-mediated adverse events in susceptible patients, we hypothesized that NOD mice can be used as a predictive tool to investigate the effects of anti–PD-1 treatment on the onset and severity of T1D, and how microbiota influences immunopathology. In this longitudinal study, we showed that anti–PD-1 accelerated T1D onset, increased glutamic acid decarboxylase–reactive T cell frequency in spleen, and precipitated destruction of β cells, triggering high glucose levels and pancreatic islet reduction. Anti–PD-1 treatment also resulted in temporal microbiota changes and lower diversity characteristic of T1D. Finally, we identified known insulin-resistance regulating bacteria that were negatively correlated with glucose levels, indicating that anti–PD-1 treatment impacts the early gut microbiota composition. Moreover, an increase of mucin-degrading Akkermansia muciniphila points to alterations of barrier function and immune system activation. These results highlight the ability of microbiota to readily respond to therapy-triggered pathophysiological changes as rescuers (Bacteroides acidifaciens and Parabacteroides goldsteinii) or potential exacerbators (A. muciniphila). Microbiome-modulating interventions may thus be promising mitigation strategies for immunotherapies with high risk of immune-mediated adverse events.
