Authors: İNCEÖZ Hansa , BAYKAL Zehra
Published: August 2023

Aims: Infraclavicular and axillary block performed with ultrasound guidance are effective peripheral anesthesia methods applied in upper extremity surgery. We aimed to compare these methods in terms of duration of the block and action, first analgesic requirement and side effects.

Methods: This prospective, randomized study was conducted for upper extremity surgery. 100 patients were included to perform infraclavicular block (Group 1, n=51) and axillary block (Group 2, n=49) USG guided. Patients are between 19 and 85 years old. Both groups were premedicated with 0.3 mg/kg midazolam or 0.5-1 μg/kg fentanyl. Both groups were treated with a mixture of local anesthetics in a total volume of 30 mL [7.5 mL 0.5% bupivacaine (Bustesin®, 56.25 mg), 7.5 mL 2% prilocaine (Priloc®, 225 mg) and 5 mL saline] was injected. Block placement time, motor and sensory tests, postoperative 2nd, 4th, 8th, 12th. and analgesic requirement at the 24th hour, Bromage scale, Verbal Rating scale, nausea vomiting, patient satisfaction, and block adequacy data were recorded.

Results: In this study, 60% of the participants included were male and 40% were female. The systolic, diastolic and mean arterial pressures were higher in group of axillary blockade than those with blockade of infraclavicular blocks. Radial, median, ulnar and musculocutaneous nerve pin-prick test loss and loss of touch test was more frequent in infraclavicular block patients. According to the Bromage scale, the partial block was seen more frequently in patients who had a close block and a full block infraclavicular block. In patients with the axillary blockade, sedoanalgesia and general anesthesia needs after postoperative intraoperative 20 min and postoperative sedoanalgesia was needed. According to the postoperative Bromage scale; complete and close to the thumb and more frequent in infraclavicular block patients. In Postop VRS, it was observed that the patients with the axillary block group had mild, moderate, and severe pain complaints. Patient satisfaction in the postoperative period was similar in both groups.

Conclusion: There is no significant difference between these techniques regarding surgical adequacy and subjective postoperative analgesia and dysesthesia. Complete and near-complete block rates in the infraclavicular block approach are minimally higher than in the axillary block approach.
A new model for estimating in-hospital mortality in patients with pulmonary embolism: PATHOS score
Authors: ALIŞKAN Halil , KILIÇ Mazlum
Published: August 2023

Aims: Pulmonary embolism (PE) is a major contributor to the death rate associated with cardiovascular diseases. The objective of this research is to evaluate the efficacy of the PATHOS score in predicting in-hospital mortality in patients diagnosed with pulmonary embolism (PE) in emergency departments (ED).

Methods: The data of patients who were visited in the ED of a third-level healthcare facility, and diagnosed with PE between 2022 and 2023 were analyzed. To examine the value of the PATHOS score in predicting mortality, through the use of Receiver Operating Characteristic (ROC) analysis, the Area Under the Curve (AUC) was determined.

Results: The study was completed with 111 patients. Of these patients, 52 (46.8%) were male and 59 (53.2%) were female. The mean age of the patients was 67.67±16.49. When the cut-off value of PATHOS score in identifying in-hospital mortality was >2, the sensitivity was 70.8%, the specificity was 71.3%, and the positive predictive value was 41.2% and the negative predictive value was 81.9%.

Conclusion: In this study, we concluded that the PATHOS score may be an effective tool for in-hospital mortality estimation of patients diagnosed with PE in the ED. However, this score needs further evaluation in large-scale and multicenter studies.

Published: August 2023

We combined the ground-based and Gaia Data Release 3 (DR3) asteroid observations to determine the masses of 20 asteroids with asteroid–asteroid close encounters. In order to take full advantage of the high-precision observations from Gaia, we use the Fisher information to select appropriate model parameters and the modified Encke’s equation of motion to construct a dynamical model complete at the level of observation precision. With diameters from literature, bulk densities of 20 asteroids are derived. The results indicate that the utilization of Gaia DR3 provides substantial benefits in terms of improving mass precision. Among the 20 asteroids analyzed in our study, we find that 10 asteroids achieved a mass precision better than 5%, and 15 asteroids better than 10%.

Most stars form in multiple-star systems. For a better understanding of their formation processes, it is important to resolve the individual protostellar components and the surrounding envelope and disk material at the earliest possible formation epoch, because the formation history can be lost in a few orbital timescales. Here we present Atacama Large Millimeter/submillimeter Array observational results of a young multiple protostellar system, IRAS 04239+2436, where three well-developed large spiral arms were detected in the shocked SO emission. Along the most conspicuous arm, the accretion streamer was also detected in the SO2 emission. The observational results are complemented by numerical magnetohydrodynamic simulations, where those large arms only appear in magnetically weakened clouds. Numerical simulations also suggest that the large triple spiral arms are the result of gravitational interactions between compact triple protostars and the turbulent infalling envelope.

Background

Lung cancer is the leading cause of cancer morbidity and mortality worldwide. Apart from tobacco smoke and dietary factors, microbial infections have been reported as the third leading cause of cancers globally. Deciphering the association between microbiome and lung cancer will provide potential biomarkers and novel insight in lung cancer progression. In this current study, we performed a meta-analysis to decipher the possible association between C. pneumoniae and human papillomavirus (HPV) and the risk of lung cancer.

Methods

Literature search was conducted in most English and Chinese databases. Data were analyzed using CMA v.3.0 and RevMan v.5.3 software (Cochrane-Mantel-Haenszel method) by random-effects (DerSimonian and Laird) model.

Results

The overall pooled estimates for HPV studies revealed that HPV infections in patients with lung cancer were significantly higher than those in the control group (OR = 2.33, 95% CI = 1.57–3.37, p < 0.001). Base on subgroup analysis, HPV infection rate was significantly higher in Asians (OR = 6.38, 95% CI = 2.33–17.46, p < 0.001), in tissues (OR = 5.04, 95% CI = 2.27–11.19, p < 0.001) and blood samples (OR = 1.40, 95% CI = 1.02–1.93, p = 0.04) of lung cancer patients but non-significantly lower in males (OR = 0.84, 95% CI = 0.57–1.22, p =0.35) and among lung cancer patients at clinical stage I-II (OR = 0.95, 95% CI = 0.61–1.49, p = 0.82). The overall pooled estimates from C. pneumoniae studies revealed that C. pneumoniae infection is a risk factor among lung cancer patients who are IgA seropositive (OR = 1.88, 95% CI = 1.30–2.70, p < 0.001) and IgG seropositive (OR = 1.50, 95% CI = 1.10–2.04, p = 0.010). All seronegative IgA (OR = 0.69, 95% CI = 0.42–1.16, p = 0.16) and IgG (OR = 0.66, 95% CI = 0.42–105, p = 0.08) titers are not associative risk factors to lung cancer.

Conclusions

Immunoglobulin (IgA) and IgG seropositive titers of C. pneumoniae and lungs infected with HPV types 16 and 18 are potential risk factors associated with lung cancer.
The North Atlantic Oscillation influence on the Debeli Namet Glacier
Authors: Jovanović Gordana
Published: August 2023

This article presents the relationship between climate variables in the Durmitor Massif (Montenegro) and the North Atlantic Oscillation (NAO). A new climate standard for temperatures and precipitation over the last 30 years has been presented. The Debeli Namet Glacier is an indicator of climate change. We have shown that the size of this glacier is affected by the NAO which mainly affects the precipitation in the accumulation period from December to March. During the ablation period from June to September, the influence of the NAO on precipitation and temperatures is less pronounced. El Niño and La Niña events are significant, especially in years with a low NAO index. The relationship between El Niño/La Niña and the NAO is still a subject of scientific debate.
Essor d’une archéologie sur le bâti en Champagne-Ardenne
Authors: Marchaisseau Vincent , Roms Cédric
Published: August 2023

L’ancienne région Champagne-Ardenne est surtout connue pour des découvertes archéologiques concernant le Néolithique, les âges des métaux ou le très haut Moyen Âge. Malgré la richesse de son patrimoine bâti médiéval et moderne conservé (édifices religieux, maisons urbaines, notamment à pans de bois, caves, etc.), l’archéologie sur le bâti est longtemps restée marginale dans la région. Elle a longtemps profité des interventions sur les tours des églises dans les années 1990-2000, avant de prendre une timide autonomie dans la première décennie du XXIe siècle. C’est réellement à partir de 2018 que les interventions d’archéologie sur le bâti (civil, militaire et religieux) se sont multipliées.
L’archéologie préventive appliquée à l’architecture civile de Metz
Authors: André Sitâ , Ferraresso Ivan
Published: August 2023

Metz fut un laboratoire de l’archéologie appliquée au bâti, en raison de l’urgence patrimoniale depuis le milieu du xixe siècle, puis grâce à l’implication et à la coordination des compétences assurées par le service régional de l’archéologie (SRA). Elle est restée un modèle presque inédit en France dans les années 1980 à 1990. Depuis 2002, les études menées par l’Inrap sur des bâtiments civils alimentent, par le biais de données fiabilisées, la recherche sur l’architecture des maisons médiévales messines ; depuis les grands ensembles patriciens jusqu’à un empochement de poutre comblé, l’échelle d’observation des vestiges est multiple. L’archéologie appliquée à l’architecture domestique est aussi une histoire du maintien, de la réutilisation et du réemploi. C’est une réflexion sur les continuités latentes des savoir-faire, des modes opératoires, des usages urbains et de leurs effets sur la ville d’aujourd’hui. Par leur étude et leur préservation in situ, les découvertes sont réhabilitées dans leur dimension devenue atemporelle, mais toujours culturelle et sans doute demain écologique. Les connaissances acquises par l’archéologie doivent être, elles aussi, réemployées localement, en constituant une banque de données, un diagramme des solutions techniques à l’attention des acteurs de la rénovation.
La légitimation par les prescriptions archéologiques des vestiges de la Grande Guerre en Champagne-Ardenne
Authors: Rabasté Yoann , Duchêne Bruno
Published: August 2023

Les nombreuses découvertes de vestiges de la Grande Guerre auxquelles les archéologues ont été confrontés dans le nord et l’est de la France depuis ces trente dernières années les ont peu à peu conduits à mener de nouvelles réflexions sur les problématiques et les contextes de ces structures récentes. Bien souvent mis de côté, pour des raisons de sécurité ou pour leur contexte jugé trop récent, ces vestiges ont pris place au fur et à mesure dans les mentalités, individuelles dans un premier temps puis collectives dans un second, modifiant leur perception et transformant les approches scientifiques. L’évolution des pensées sur la légitimité de ces structures de l’ère industrielle a donc engendré une volonté de les inscrire dans les prescriptions archéologiques champenoises, au même titre que les vestiges des périodes plus anciennes.
Archéologie des occupations amérindiennes dans l’hinterland guyanais
Authors: Gassies Éric , Mestre Mickaël
Published: August 2023

La recherche archéologique en forêt amazonienne s’est en permanence réinventée en fonction des conditions particulières imposées par le milieu et des stratégies adoptées pour y répondre. Deux nouvelles technologies ont complètement révolutionné les modes opératoires pour la détection des sites archéologiques en forêt amazonienne : le GPS et le LiDAR. Parmi les « anomalies graphiques », les plus spectaculaires qui ressortent des traitements de données figurent les géométries des sites à fossé, dénommées localement « montagnes couronnées », vestiges d’aménagement anthropique, considérés comme extrêmement rares et qui se sont avérés relativement nombreux. L’expérience acquise à partir des vérifications opérées sur le terrain montre aussi la forte présence d’autres types d’occupation humaine qui ne présentent pas de microreliefs particuliers.
Expérimentations techniques à Lavau. Mécanisation, relevés et prélèvements
Authors: Dubuis Bastien , Millet Émilie
Published: August 2023

Le site du Moutot à Lavau (Aube), fouillé sur 2 hectares par l’Inrap en 2014-2015, correspond à un complexe funéraire monumental occupé à plusieurs reprises, entre le Hallstatt A1 et la fin de l’Antiquité. Il se caractérise d’abord par sa stratigraphie, obligeant à un décapage délicat et au relevé de grandes longueurs de coupe. La conservation partielle de plusieurs élévations tumulaires a permis l’appréhension des pratiques et de l’architecture funéraires sur le temps long. De manière inattendue, la fouille a permis de documenter une exceptionnelle tombe princière du Ve siècle avant notre ère, dont l’étude a nécessité une adaptation technique et méthodologique constante. Fouille de longue haleine, partagée entre les recherches menées sous abri et sur plateaux mobiles de la tombe du prince et l’examen tous azimuts de son contexte, l’opération de Lavau constitue aujourd’hui un cas unique dans le paysage de la recherche.

Published: August 2023

A series of illnesses known as glaucoma harm the optic nerve in the eye. Glaucoma can cause lifelong blindness or vision loss if it is not addressed. Because glaucoma frequently has no symptoms in its early stages, it is particularly difficult. If symptoms start to show up, it might be too late to stop blindness. There are numerous ways to identify glaucoma, including tonometry, which measures the pressure inside the eye, ophthalmoscopy, which looks at the optic nerve's form and color, and perimeter, which measures the entire field of vision. However, because of the fact that each person's glaucoma is unique, these procedures do not allow for the detection of all forms of glaucoma. A visual assessment technique that can identify glaucoma is cup-to-disc ratio. By image processing methods like binarization the cup-to-disc ratio is calculated in this project and utilized to assess the glaucomatous status of an eye using super pixel classification.

Published: August 2023

This study focuses on investigating energy-aware resources and designing an energy-efficient cloud architecture. It aims to optimize the decentralization model and establish migration behavior to improve IT business operations using cloud computing. Several models were evaluated for performance metrics such as physical host use, power utilization, and service level agreement (SLA) misuse. These models include smart cloud optimization for resource configuration handling (SCORCH), V-MAN, decentralized energy-aware collaborative model (DEACM), efficient energy-aware resource management model (EEARMM), and energy and power-aware dynamic migration (EPADM). To handle resource configuration efficiently, the study employed V-MAN, DEACM, EEARMM, and EPADM within the framework of smart cloud optimization. Among these models, EPADM proved to be the most effective for resource utilization through dynamic VM migration. By leveraging EPADM, the cloud system can dynamically migrate virtual machines (VMs) to optimize resource allocation and energy consumption.

Este estudo quase-experimental avaliou os efeitos de dois programas de exercício físico, ofertado no contexto das aulas de Educação Física escolar, sobre indicadores de aptidão física. A amostra por conveniência foi composta por 91 alunos com idades entre 9-12 anos que formaram os grupos Formação Corporal (PFC; 45 alunos) e Educação Física (PEF; 45 alunos). Foi mensurado o índice de massa corporal (IMC), aptidão cardiorrespiratória (ApC), flexibilidade e força muscular localizada (FML). Recorreu-se ao “Teste t pareado” e ANOVA de medidas repetidas. O tamanho do efeito foi estimado pelo “eta ao quadrado parcial”, estratificado por sexo, sendo aceito a probabilidade de 5% de erro. Os resultados mostraram nos meninos efeito muito elevado no grupo PFC na ApC, flexibilidade e FML e efeito elevado no grupo PEF na flexibilidade e FML. Nas meninas efeito muito elevado no grupo PFC na ApC, flexibilidade e FML e no grupo PEF efeito muito elevado na flexibilidade e FML e de efeito elevado na ApC. Não houve efeito no IMC em ambos os grupos. Ressaltamos que este único encontro semanal (15 minutos de PFC) foi capaz de apresentar efeito muito elevado e elevado na aptidão física a favor do PFC em ambos os sexos.

Published: August 2023

O uso do acelerômetro para mensurar a atividade física em pesquisas epidemiológicas, apresenta desafios para aumentar a comparabilidade entre os estudos que utilizam esse equipamento. Nesse sentido o objetivo deste trabalho é comparar estimativas de tempo em AFMV para adultos provenientes de diferentes métodos de processamentos de dados, através do acelerômetro Actigraph GT3X+. Trata-se de um estudo transversal, da linha de base do estudo piloto do Estudo Longitudinal dos Determinantes da Atividade Física. Amostra contou com 31 funcionários terceirizados de ambos os sexos, com idade média de 47.05anos (DP=9.35). Os participantes utilizaram acelerômetros do modelo GT3X+ durante sete dias consecutivos. A estimativa de tempo de AFMV foi gerada através de software Actilife e R-package GGIR. Análises estatísticas descritivas, ANOVA e pos-hoc de Bonferroni para comparabilidade foram realizadas no software R. Análise de Bland-Altman foi realizado no SigmaPlot para avaliação de viés e concordância. Houve diferença significativa no tempo médio de AFMV entre os dados baseados em counts e dados brutos (p<0,001). O tempo médio em AFMV foi menor a partir do processamento por dados brutos do que o em counts (-264,81min/dia; p<0,001). Concluindo que os achados sugerem não haver, estatisticamente, equivalência entre os métodos comparados para estimar tempo de AFMV.

Published: August 2023

This study compared the frequency, number of goals and attack efficiency in temporal numerical superiority among winning and losing teams and among balanced and unbalanced matches in a junior men’s water polo competition. Another analysed relationship was that between a balanced or unbalanced final score and the efficiency at scoring goals in numerical superiority in the winning teams’ games. A total of 56 matches from the Pan-American Junior Men’s Water Polo championship was analysed. The teams were categorised as losers or winners and the match results were classified as balanced or unbalanced. The chi-squared and Mann-Whitney tests were used for statistical treatment. There is no significant difference in the occurrence of numerical superiority between winners and losers (p = 0.25) despite the winners scoring more goals (p = 0.002) and being more efficient (p < 0.001). There is no significant difference in the occurrence of numerical superiority (p = 0.81) and goals (p = 0.03) in balanced and unbalanced matches. However, there tends to be a higher shot efficiency (p = 0.01) in unbalanced matches. A significant relationship exists (p = 0.04) between the winning teams’ efficiency at scoring goals in a situation of numerical superiority and an unbalanced score.

Published: August 2023

O objetivo do estudo é investigar como o desempenho do saque do voleibol de sujeitos com diferentes níveis de experiência é influenciado pela interação de diferentes restrições. Participaram do estudo 36 voluntários do sexo masculino (16,44 ± 0,50 anos) alocados em dois grupos em função do nível de experiência. Os participantes executaram 10 tentativas do saque do voleibol em cada uma das quatro condições experimentais. Foram manipuladas uma restrição relacionada à dificuldade da meta e outra relacionada ao ambiente físico para execução da tarefa. O desempenho do saque por cima do voleibol foi avaliado por meio de uma lista de checagem do padrão de movimento e da precisão ao alvo. Os resultados demonstraram que o grupo experiente manteve o desempenho em todas as condições, enquanto o grupo inexperiente apresentou menor consistência da precisão nas condições com restrição física e pior escore do padrão de movimento na condição de maior dificuldade da meta em interação com a restrição física. O nível de experiência exerceu maior influência no desempenho do que as demais restrições. Uma possível explicação é que ela é uma restrição capaz de maximizar a forma como o sujeito explora as informações disponibilizadas pelas demais restrições.

This study objective to compare the acute effects between one resistance training bout with high versus moderate intensities on inflammatory markers in women with severe obesity. Experimental crossover study, performed with adult women with severe obesity (BMI ≥ 40.0 kg/m²; age ≥ 18 years old). Each participant performed a high and moderate intensity resistance training (HIRT and MIRT, respectively) with an interval of 7 days between bouts. Four exercises were performed in the both protocols, with total training volume equalized. MIRT consisted of 3 sets of 8 repetitions each, with an intensity of 75% of 1RM, while HIRT consisted of 2 sets of 6 repetitions, followed by a 20-second rest, with a new performance of 2 to 3 repetitions, with one more rest of 20s and finishing with 2 to 3 more repetitions, at an intensity of 85% of 1RM. Blood samples were collected before, 15 minutes after and 24 hours after both training protocols. The inflammatory markers analyzed were IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ. Nine participants have completed the intervention (n=9; 35.2 ± 10.93 years old; BMI = 48.3 ± 5.06 kg/m²). The Mann-Whitney U test showed that there was no significant difference between the HIRT and MIRT in the concentration of markers. Friedman's test did not report significant differences between intragroup measures for the HIRT as well as MIRT. This research suggests that a single session of high or moderate intensity resistance training does not change the inflammatory status of women with severe obesity.

Authors: Ziab Hussein , Ammash Mohammad , Hariri Hussein , Alaaeddine Hussein
Published: August 2023

Background: Sports participation motivations can be intrinsic, extrinsic, or even amotivational. Few studies on adult participation in PA have been found in the Lebanese context. This study aims to: a) investigate significant differences in sports participation motivation across gender, age, occupation, and time of practice, and b) investigate sports participation motives that discriminated the best between those variables.Material and methods: The Arabic version of the Sport Motivation Scale was collected electronically from 568 volunteers practicing regular PA for the last six months. Gender, occupation, marital status, and time of practice were all analyzed using Mann-Whitney U test and the Kruskal Wallis Test with 0.05 as level of significance.Results: Internal motivation subscales (particularly the intention to accomplish) were the most influential motives for both genders. A significant difference across gender was reported in the extrinsic motivation and amotivation subscales. Furthermore, age, occupation, marital status, and time of practice show significant differences in motivation factors either dependent or regardless of gender distribution (p<0.05).Conclusion: no significant differences in the intrinsic motivation for sports participation between genders. Other factors, on the other hand, had a substantial impact.Research contribution: these findings are intended to contribute to a better understanding of differences in motivation for participating in PA and to aid in its promotion among Lebanese adults.

Esse estudo teve por objetivo avaliar o efeito da padronização dos critérios de observação e de avaliação da técnica da braçada do nado crawl na confiabilidade inter e intra avaliadores para uma proposta de lista de observação. Dois professores e dois treinadores de natação competitiva com formação acadêmica diferentes foram responsáveis por avaliar a técnica da braçada do nado crawl de 44 nadadores por meio de vídeo. Cada nadador realizou um percurso de 25m em velocidade confortável tendo seu deslocamento gravado nos planos lateral e frontal, ambos submersos e fora d’água, nos 10 m finais da piscina. No percurso de filmagem os nadadores não realizaram a respiração lateral. Somente o movimento realizado pelo braço direito foi foco de observação dos avaliadores e com base em uma lista de verificação. Após as filmagens os avaliadores participaram de três etapas: na primeira etapa houve uma intervenção para padronização dos critérios de observação e de avaliação. Na segunda etapa testou-se a concordância inter-avaliadores e, na terceira, a concordância intra-avaliador. Na segunda etapa do estudo a concordância variou de pequeno a baixa (k=0,08 e k=0,38). Na terceira etapa alguns avaliadores apresentaram concordância pobre e baixa (k=-0,13 e k=0,35), enquanto outros apresentaram concordância entre razoável e praticamente perfeita (k=0,64 e k=0,87). A partir dos resultados apresentados concluiu-se que a proposta de intervenção não surtiu o efeito desejado de padronização dos critérios de observação e avaliação entre os avaliadores

Novas formas de se obter informações sobre o comportamento sedentário (CS) têm sido exploradas recentemente. O objetivo do estudo foi verificar a concordância da postura auto-relatada por meio da avaliação momentânea ecológica (AME) com as imagens enviadas por meio de um protocolo de observação criado em um formulário respondido pelo telefone celular de adultos jovens. Foi utilizado um banco de imagens fornecidos por 41 universitários, obtidas por um projeto realizado em 2019, analisando a posição: sentada, deitada/reclinada ou em pé, comparando a imagem fornecida com o CS auto-reportado por meio da AME, que foi coletada por telefone celular. A concordância foi realizada por dois pesquisadores de modo independente. A análise dos dados foi realizada pela estatística descritiva, t de Student, qui-quadrado e k de Cohen no SPSS 25 com P<0,05. A concordância entre os avaliadores foi forte/substancial de 87,6% (avaliador 1; k = 0,696) e de 88,6% (avaliador 2; k = 0,720). O protocolo de observação por imagem criado por formulário eletrônico conseguiu discriminar o comportamento adotado pelo participante, bem como viável de ser utilizado de modo independente, somente para o registro da AME e/ou da imagem/fotografia.

Body mass is known to affect muscle strength and the outcome of some functional tests, so that heavier and taller people will be stronger than lighter and smaller ones. Ratio standard (RS) has been widely used to remove the body mass effect, despite long date criticism due to its inadequacy. Allometry (ALLO), in turn, has been applied as an efficient method for normalizing muscular strength. As the bench press (BP) is a well-recognized strength and conditioning exercise for older adults, the aim of the present study was to verify the influence of body mass on the performance assessment of a group of older men in the BP, by comparing the absolute, RS and ALLO approaches. Sixteen healthy old men (65.5±5.13 years old; 75.42±9.78Kg; 1.73±5.98m; 25.11±2.71 kg/m2; 24.76±4.10 %fat) volunteered to participate in the study. Maximum dynamic load was verified by individual one-repetition maximum (1-RM) tests. Comparisons of means revealed that significant 1-RM difference between lighter (54.9±8.85Kg) and heavier (66.2±8.86Kg) participants was identified only in absolute approach (p<0.05; ES=0.57). RS failed in completely remove the body mass effect, allowing correlation between normalized muscular strength and BM (r=0.23), in contraire of ALLO (r=0.03 and 0.06). Kendall's concordance coefficient revealed an absolute lack of agreement between approaches when compared their respective ordinal classifications (kw=0.003; p>0.05). In line with previous research, ALLO has shown to be the only suitable method to remove adequately the body mass effect and to provide appropriated performance scores for the older men evaluated in this study.

Introduction

Acute myeloid leukemia (AML) is a malignant disorder of clonal hematopoietic stem cell, characterized by the rapid proliferation of leukemic blasts leading to abnormal accumulation of immature precursors and suppression of growth and maturation of cells involved in normal hematopoiesis. Several studies have elucidated the physiological roles of microRNAs (miRNA) as key regulators of hematopoiesis. Growing evidence shows that miRNA 370 may function either as a tumor suppressor or as an oncogene in various human cancer types, implying its crucial role during tumor development and progression.

Objective

The aim was to evaluate miRNA 370 expression level in patients with AML compared with healthy control and also the diagnostic and prognostic value of miRNA 370 in AML.

Patients and methods

This study was carried out on 80 participants to evaluate the role of miRNA 370 in AML. Group I (case) included 60 patients diagnosed with AML, and group II (control) included 20 healthy individuals. Quantitation of miRNA 370 was done by real-time PCR in the peripheral blood.

Results

Patients with AML had significantly higher miRNA 370 values (1.6 ± 2.8 vs. 0.24 ± 0.11; P=0.001). miRNA 370 had a sensitivity of 73% and specificity of 65% for the discrimination between AML and normal controls (area under the curve=0.80, 95% confidence interval=0.71–0.89). There was a significant association between miRNA 370 and FAB classification (P=0.001).

Conclusion

miRNA 370 is a potential diagnostic and prognostic marker for AML.
Intradermal platelet-rich plasma for the treatment of melasma: A clinical and dermoscopic evaluation in dark skin
Authors: Rout Aradhana , Mani Siddharth , Bala Nishu
Published: August 2023

Background:

Melasma is a common dermatosis in both men and women showing varying degrees of success with treatment. Relapse of melasma is high in dark skin types, which necessitates the need for finding a modality of treatment, which not only treats but also prevents relapse.

Aims:

To study the effectiveness of platelet-rich plasma (PRP) in patients of melasma both clinically and dermoscopically in dark skin types.

Materials and Methods:

A prospective study of 20 female patients of Fitzpatrick skin type IV–V with mixed type of melasma and bilateral involvement of the face were enrolled for the study. PRP was injected intradermally at 4 weeks interval for three sittings, and the results were assessed clinically (by modified melasma area and severity score) and dermoscopically. Patients were counselled to ensure strict sun protection measures. Patient satisfaction was noted at baseline, 4 weeks, 8 weeks, and 12 weeks. Patients were followed up for 3 months to see for any relapse of the pigmentation. The follow-up showed no relapse of melasma in these patients.

Statistical Analysis:

Analysis of variance was used with Bonferroni correction for modified melasma area and severity score at various time interval. Subject global aesthetic improvement scale (SGAIS) and physician global esthetic improvement scale (PGAIS) were expressed in counts. P-value ≤ 0.05 was considered significant.

Results:

Modified melasma area and severity score and dermoscopic changes showed statistically significant improvement compared at the end of study in mild to severe cases. The subjective assessment was made by PGAIS. Patient satisfaction levels (assessed by SGAIS) also showed significant improvement in successive weeks of treatment. Few patients had mild redness and burning post procedure, which resolved spontaneously after few hours.

Conclusion:

From this study we concluded that PRP shows a significant improvement in melasma after 12 weeks of treatment with no relapse even after 3 months. Hence, PRP may be used not only as an adjuvant but also as a first line treatment in the view of longer sustained results when combined with strict sun protection. There is a paucity of studies showing results of PRP treatment in dark skin types, which is more resistant to treatment than lighter skin. Moreover, clinical improvement should not be the only parameter to decide on stopping treatment as chances of relapse can be higher. Dermoscopic evaluation helps in determining the changes in vasculature (telangiectasias) and pigmentation (dots and globules), which are better indicators of success of treatment.
Polydioxanone bioactive sutures—Acetyl hexapeptide-8 (Argireline): An intelligent system for controlled release in facial harmonization
Authors: Velazco de Maldonado Gladys J , Suárez-Vega Dubraska V , Miller-Kobisher Blanca , García-Guevara Víctor J
Published: August 2023

Introduction:

We propose a new facial lifting protocol using polydioxanone (PDO) threads embedded in acetyl hexapeptide-8 (Argireline [Arg]). We assume that Arg reinforces the effects of PDO threads, as it is a mimetic of botulinum toxin. Because the PDO suture is hydrolyzable, this assumption is analyzed by instrumental analysis.

Objective:

To demonstrate the capacity of the PDO suture as a system for the controlled release of acetyl hexapeptide-8 to apply in deep wrinkles of the upper third.

Materials and Methods:

Three segments of 1-cm long 21G PDO threads immersed in 1 mL of Arg. PDO threads were observed under an optical, electron microscope at 24, 48, and 72 h later. They were also weighed before and after being soaked in Arg, and employing ultraviolet (UV)-visible spectroscopy, the release rate of Arg from the PDO suture was measured. Finally, was insert the thread PDO-Arg following a protocol designed especially for deep static wrinkles in the upper third.

Results:

The electronic weighing revealed that the PDO thread enjoys capillarity by the peptide, doubling its weight every 24 h. UV spectra revealed that PDO thread is a well-controlled release system for Arg, allowing its sustained release for 1 h. Optical and electronic photomicrographs confirm the swelling of the PDO thread by absorbing Arg by its capillarity, but this hydrophilicity does not lead to its premature physical degradation.

Conclusions:

The PDO thread system with Arg is an intelligent bioactive system useful in facial harmonization. It recommend conduct clinical trial to verify his superior lifting effect.

The detection of thyroid cancer in patients with Graves’ disease (GD) is rare. The prognosis of thyroid cancer in patients with concomitant GD is controversial. Here, we present a rare case of papillary thyroid carcinoma (TC) associated with GD in a 23-year-old woman who presented with goiter and thyrotoxicosis symptoms and was initially diagnosed as GD. However, she underwent further investigations in view of suspicious findings and was found to have TC. The patient was subjected to surgery after controlling thyrotoxic features with the help of antithyroid medications.
