Meta-analysis of transarterial chemoembolization combined with cryoablation vs transarterial chemoembolization alone for ≥ 5 cm hepatocellular carcinoma
Authors: Cheng Jie-Fei , Sun Qiu-Lian , Tang Ling , Xu Xin-Jian , Huang Xiang-Zhong
Published: June 2024

BACKGROUND

Hepatocellular carcinoma (HCC) ranks sixth globally in cancer incidence and third in mortality rates. Unfortunately, over 70% of HCC patients forego the opportunity for curative surgery or liver transplantation due to inadequate physical examinations, poor physical condition, and limited organ availability upon diagnosis. Clinical guidelines endorse transarterial chemoembolization (TACE) as the frontline treatment for intermediate to advanced-stage HCC. Cryoablation (CRA) is an emerging local ablative therapy increasingly used in HCC management. Recent studies suggest that combining CRA with TACE offers complementary and synergistic effects, potentially improving long-term survival rates. However, the superiority of combined TACE + CRA therapy over TACE alone for HCC lesions equal to or exceeding 5 cm requires further investigation.

AIM

To compare the efficacy and safety of TACE combined with CRA vs TACE alone in the treatment of HCC with a diameter of ≥ 5 cm.

METHODS

PubMed, EMBASE, Cochrane Library, CNKI, Wanfang, and VIP databases were searched to retrieve all relevant studies on TACE and CRA up to July 2022. Meta-analysis was performed using RevMan 5.3 software.

RESULTS

After screening according to the inclusion and exclusion criteria, 6 articles were included, including 2 randomized controlled trials and 4 nonrandomized controlled trials, with a total of 575 patients included in the meta-analysis. The results showed that the objective response rate [odds ratio (OR) = 2.56, 95% confidence interval (CI):1.66-3.96, P < 0.0001), disease control rate (OR = 3.03, 95%CI: 1.88-4.89, P < 0.00001), 1-year survival rate (OR = 3.79, 95%CI: 2.50-5.76, P < 0.00001), 2-year survival rate (OR = 2.34, 95%CI: 1.43-3.85, P = 0.0008), and 3-year survival rate (OR = 3.34, 95%CI: 1.61-6.94, P = 0.001) were all superior to those of the control group; the postoperative decrease in alpha-fetoprotein value (OR = 295.53, 95%CI: 250.22-340.85, P < 0.0001), the postoperative increase in CD4 value (OR = 10.59, 95%CI: 8.78-12.40, P < 0.00001), and the postoperative decrease in CD8 value (OR = 6.47, 95%CI: 4.44-8.50, P < 0.00001) were also significantly higher than those in the TACE-alone treatment group.

CONCLUSION

Compared with TACE-alone treatment, TACE + CRA combined treatment not only improves the immune function of HCC patients with a diameter of ≥ 5 cm, but also enhances the therapeutic efficacy and long-term survival rate, without increasing the risk of complications. Therefore, TACE + CRA combined treatment may be a more recommended treatment for patients with HCC with a diameter of ≥ 5 cm.
Effects of Dimethyl Ether and Propane Blends on Knocking Behavior in
a Boosted SI Engine
Authors: Soto Lian , Han Taehoon , Boehman Andre L.
Published: June 2024

Dimethyl ether (DME) is an alternative fuel that, blended with propane, could be
an excellent alternative for exploring the use of fuels from renewable sources.
DME–propane blends are feasible for their comparable physicochemical properties;
these fuels may be pressured as liquids using moderate pressure at ambient
temperature. Adding a proportion of DME with a low octane number to a less
reactive fuel like propane can improve the combustion process. However, the
increased reactivity of the mixture induced by the DME could lead to the early
appearance of knocking, and this tendency may even be pronounced in boosted SI
engines. Hence, this study experimentally analyzes the effect of E10 gasoline
(baseline) and DME–propane blends, with varying proportions of DME in propane
ranging from 0% to 30% by weight, in increments of 5% on knocking tendency,
combustion characteristics, gaseous emissions, and particle number
concentration, under different intake pressure conditions (0.8, 0.9, 1.0, and
1.1 bar) in an SI engine. The results show that as the proportion of DME in the
propane blend rises, the knocking tendency becomes more pronounced. That
behavior intensifies with increasing intake pressure, but with 20% DME in the
propane blend, reaching the maximum brake torque (MBT) without knocking in the
four boosted conditions is feasible. The presence of knock limited the advance
of combustion phasing and decreased the gross indicated thermal efficiency
(ITEg) with E10 gasoline and 25% and 30% DME in propane blends under 1.0 and 1.1
bar boosted conditions. In these knock-limited circumstances, the NOx emissions
decreased due to the retarded phasing, and THC and PN emissions increased due to
the lower combustion stability, considerably raising the concentration of
accumulation mode particles in the particle size distribution (PSD) compared to
the other fuel blends tested.

Ground and abrasive stone tools had a long, dynamic and complex life during which they could repeatedly pass through different segments of the operational chain until their final disposal. Those tools would wear out slowly and could be used for a long time with constant renewal. Even after being damaged, they would start a new life cycle through various recycling processes or in a secondary context. The aim of this paper is to consider the transformative processes within the ground and abrasive stone industry in the Neolithic of Serbia and clarify their use in terms of maintenance, secondary use, and recycling, as well as to show the most frequent examples of such technological practices. The focus is primarily on tools for everyday use and the ways in which they were rerouted through various segments of the operational chain.

distinção e a interseção de legados: nexos e diferenças estruturais entre Benjamin de Oliveira e Chiquinha Gonzaga
Authors: Rocha Maristela
Published: June 2024

As últimas décadas do século XIX são de notória relevância para a história da música brasileira, já que nesse período as influências europeias começaram a ser impactadas pela emergente cultura urbana, que se consolidou ao longo do século XX. Vários artistas com habilidades múltiplas se destacaram naquele tempo, como o compositor, cantor, instrumentista, ator, diretor e palhaço mineiro Benjamim de Oliveira (1870-1954), cuja contribuição para o processo de inserção do circo-teatro na produção circense no Brasil demanda ser rememorada, sobretudo após os seus 150 anos de nascimento. Outra personalidade a ser contemplada neste artigo é a pianista, compositora e maestrina Chiquinha Gonzaga (1847-1935), pioneira em vários aspectos na cultura nacional: figura feminina insigne, cuja contribuição também ainda não teve o reconhecimento por parte da memória coletiva do povo brasileiro. Através de pesquisa bibliográfica e documental serão analisadas questões estruturais, distinções e interseções que circundaram a produção dos dois artistas, imersos em um Brasil dominado pelo colonialismo em todos os âmbitos. Utilizaremos vários anúncios e excertos de jornais digitalizados ao longo do texto para referendar nossas informações.

Is it possible to propose a periodization strategy different from the inverted U in preseason? A comparison between two professional football teams
Authors: Castellano Julen , Casamichana David , Agirrezabalaga Oier
Published: June 2024

Purpose: the main aim of this study was to quantify and compare the weekly external loads of pre-season in two professional football teams. Methods: GPS devices monitored forty-five players in two teams daily in a five-week pre-season period. The external load measures were: number of sessions, total duration, acceleration load (aLoad), total distance (TD), distance at >21 km·h-1 (TD21), distance at >24 km·h-1 (TD24) and Player-Load® (PL). Results: there were differences in the weekly external load between both teams. Team1 trained 30% more time and training sessions than Team2, so the weekly load for all external load variables was higher except for aLoad and TD21 for W1 (Team2>Team1, p<0.05). These differences between teams were not similar for all weeks, with higher differences in weeks 2, 3, and 4. While Team2 proposed a distribution more stable and progressive in high-speed distances (TD21 and TD24) among weeks, Team1 used the inverted U model. In this line, variations between weeks were lower for Team2 (from -4% to 38%) than for Team1 (from -26% to 1,653%). Conclusions: The study's main conclusion was that in addition to a load management with an inverted U model, more widespread in professional football, a more stable and progressive distribution strategy can be proposed in pre-season in a professional setting.

The Development of the National Football Development Program (NFDP) Coaching Process Model: Emphasis on Small Sided Game (SSG) Approach
Authors: Karim Zulakbal Abd , Razak Asraf , Ismail Fakrul Hazely , Muhammad Abdul Rahman , Ali Syed Kamaruzaman Syed , Akbar Amin
Published: June 2024

Small-sided games (SSGs) are played on reduced pitch areas, often using modified rules and involving a smaller number of players than traditional football. These games are less structured than traditional fitness training methods but are very popular training drills for players of all ages and levels. At present, there is relatively little information regarding how SSGs can best be used to improve physical capacities and technical or tactical skills in footballers. However, many prescriptive variables controlled by the coach can influence the exercise intensity during SSGs. In the context of soccer instruction, SSGs are frequently employed to give an engaging method of preserving the dynamics of an official game while making particular alterations to concentrate on certain behaviors and movements. Models for coaching provides some insight and guidelines into what coaches do. The purpose of the study is to build a coaching process model based on the "Small Sided Game" approach. The qualitative method was conducted in this study. The researcher used snowball sampling in which 10 sports schools coaches under NFDP program were interviewed. The numbers of participants were determined by saturation of information. The variation in exercise intensity during SSGs can improved with consistent coach encouragement but it is still more variable than traditional generic training methods. SSGs containing fewer players can exceed match intensity and elicit similar intensities to both long- and short-duration high- intensity interval running. This study implied the construction of the football coaching process model that can benefit the national football development at the grassroots level and provide alternative sources of knowledge for teachers or football coaches to coach their football teams.

Consuming soy flour after weight training: An alternative to increase leg muscle strength
Authors: Welis Wilda , Effendi Rully , Mario Deby Tri , Ilham Ilham , Ihsan Nurul
Published: June 2024

The aim of this study was to find out whether soybean flour and lunge training can have a significant effect on muscle strength. This research method is a pre-test-post-test design (quasi-experiment). Using a total sampling technique, 14 Indonesian PPLP West Sumatra Pencak Silat athletes were used as research samples. The research procedure included measuring muscle strength (leg dynamometer) before administering 29g protein after lunges training (pre-test). Then the treatment was given in 16 meetings, with a frequency of 2 sessions per week for 8 weeks. The intensity of the training/intervention given was submaximal (80% to 90% of maximum capacity). Giving soy flour to athletes 30 minutes after training is in accordance with the protein requirements given to athletes in each session, namely 29 grams of protein equivalent to 73 grams of soy flour with the addition of 1 tablespoon of granulated sugar and 200 ml of water. The results of statistical tests using the t test showed that testing the data resulted in (p<0.05) a percentage increase of 6.91%. In conclusion, adding protein supplementation to support weight training can increase muscle strength. Planned, structured and consistent exercise is necessary for any protein supplement to work. The use of this protein supplement must be adjusted to the needs of each participant to get the best preparation results. The findings of this research can be used by athletes who want to or are currently implementing a training program, as well as coaches as evaluation material, and nutritionists as material experts.

Aging is habitually related to modifications in the peripheral, central nervous and musculoskeletal systems. These modifications are frequently associated with mobility complications. It is currently considered that the spatiotemporal gait parameters (SGP) may be good functional indicators of the severity of knee osteoarthritis (KOA). Objective: to compare the SGP in middle-age and older women with different radiographic KOA diagnosis. Methods and materials: For this, ninety-nine (99) female participants (age: 61.0±3.0 years; body mass: 72.9±13.4 kg; height: 1.5±0.1 m; BMI: 31.2±5.7 Kg/m2) were enrolled in a cross-sectional design. All participants were classified according to the Kellgren-Lawrence radiological scale (None n=15; Doubtful n=24; Minimal n=22; Moderate n=20 and Severe n=18). All participants performed a 25-m Walk test for which the SGP was measured (cadence, duration of monopodal support phase, and stride length). Results: No differences were observed in any SGP measures (cadence, p=0.57; monopodal support phase, p=0.65; and stride length, p=0.22). Conclusion: Our results showed that there is no agreement between the SGP and radiographic KOA diagnosis.

Objetivo: Avaliar a influência do paradesporto na qualidade de vida de pessoas com deficiência motora. Metodologia: Estudo quantitativo transversal realizado com 351 paraatletas (X ̅ = 30,9 ± 11,7 anos) e 90 não atletas com deficiência motora (X ̅ = 31,6 ± 9,3 anos). Foi aprovado pelo Comitê de Ética em Pesquisa da Universidade do Estado do Pará (CAAE nº 51930821.2.0000.5174), sob protocolo nº. Decreto nº 5.012.266, de 1º de outubro de 2021. Os dados foram coletados por meio de questionário do Google Forms. A qualidade de vida foi avaliada por meio da aplicação do Questionário de Qualidade de Vida da Organização Mundial da Saúde - WHOQOL-100. Os dados foram apresentados por meio de estatística descritiva e submetidos a análises inferenciais por meio de testes não paramétricos, uma vez que a distribuição dos dados não era normalmente distribuída. O teste não paramétrico de Mann-Whitney foi aplicado para comparações intergrupos de variáveis ​​contínuas. Para variáveis ​​discretas e/ou nominais foi utilizado o teste qui-quadrado de Pearson, ambos com nível de significância de p < 0,05 para rejeitar a hipótese nula. Resultados: Os para-atletas apresentaram melhor qualidade de vida que os não-atletas (∆% = 12,97%, p = 0,02), alcançando um índice geral de 14,20, classificando-os como elevados (acima de 14 pontos). Este resultado se deve principalmente ao Domínio 6 (Espiritualidade), onde este grupo obteve índice de 16,90, superior ao grupo de não atletas neste domínio (∆% = 16,69%). Conclusão: Em relação às suas deficiências físicas, o grupo para-atleta apresentou melhor qualidade de vida do que seus colegas não atletas. Pode-se inferir que a prática do paradesporto pode ter ajudado as pessoas com deficiência física a superarem suas limitações.

This study aims to optimize recovery after acute exercise using a high-intensity interval method involving the strategy of providing massage to athletes. Exercise heart rate (HR Ex), heart recovery rate (HRR), and blood lactate levels are used as parameters of physiological fatigue due to physical exercise. 24 samples participated in this research; they were divided into 3 groups, namely the during and post-massage group (DPM), the post-massage group (PM), and the control group, namely passive recovery (PR). Each group consists of 8 samples; all samples will carry out high-intensity acute exercise using the Tabata method for 4 sessions. 1 training session is carried out for 4 minutes, and the rest for each session is 4 minutes. Descriptive analysis, paired sample t-tests, and two-way ANOVA were used in data analysis. The results of this study were that all data on fatigue indicators were normally distributed (p ≥ 0.05) and homogeneous (p ≤ 0.05), and there were differences in lactate concentrations at each time taking the lactate levels in each group (p ≤ 0.05). The average blood lactate levels of the three groups were stated to be significantly different after the training program ended for the DPM group (10.30±1.78 mmol/L), PM (12.9±2.05 mmol/L), and PR (13.62±2.87 mmol/L). This research concluded that giving massage has a better effect than passive recovery on recovery in terms of both heart rate and lactate levels. A recovery strategy using massage is the best strategy for managing blood lactate levels, although trainers must understand that giving a massage during training breaks and after the training program ends gives a different response to lactate levels after training ends.

Published: June 2024

Partiendo de las aportaciones de la neurociencia, que sugieren que es posible considerar la hiperreactividad del cortisol como un biomarcador para el tratamiento e intervención de población con trastorno de estrés postraumático que sufrió adversidad temprana, se presenta una investigación realizada con nueve niños/as que reciben atención psicomotriz. Se midieron los niveles de cortisol antes y después de recibir la intervención durante cuatro semanas, utilizando un método competitivo inmuno-enzimático (ELISA) para la determinación de las cifras de cortisol libre en orina. Los resultados del estudio ponen en evidencia que la psicomotricidad relacional puede ofrecerse como una metodología de intervención eficaz para disminuir el estrés que acompaña a esta población en sus vivencias diarias. En todas las sesiones se disminuyen los niveles de cortisol, obteniéndose un alto nivel de significación en el análisis de Wilcoxon al comparar los niveles de cortisol antes de la primera sesión y tras finalizar la cuarta. Además, se refiere una gran variabilidad entre los niveles de cortisol de los que parte cada uno de los sujetos, siendo más elevados los valores totales en el género masculino.

Abstract. Based on contributions from neuroscience, which suggest that it is possible to consider cortisol hyperreactivity as a biomarker for the treatment and intervention of a population with post-traumatic stress disorder who suffered early adversity, a research is presented on nine children receiving psychomotor care. Cortisol levels were measured before and after receiving the intervention for four weeks, using a competitive enzyme-linked immunosorbent assay (ELISA) method for the determination of free cortisol in urine. The results of the study show that Relational Psychomotricity can be offered as an effective intervention methodology to reduce the stress that come along with this population in their daily lives. Cortisol levels decreased in all sessions, with a high level of significance obtained in the Wilcoxon analysis when comparing cortisol levels before the first session and after finishing the fourth one. In addition, a great variability is reported between the cortisol levels of each of the subjects, with the total values being higher in the male gender.

Frecuencia de zancada durante la carrera de resistencia en tapiz rodante y al aire libre (Stride frequency patterns during both treadmill and outdoor running in endurance runners)
Authors: Miqueleiz Unai , Cabello-Olmo Miriam , Aguado-Jimenez Roberto
Published: June 2024

Los objetivos fueron i) estudiar la concordancia entre un reloj deportivo (Suunto Ambit2) y un sistema fotoeléctrico (Optogait) como instrumento referencia para medir la frecuencia de zancada (FZ) y la longitud de zancada (LZ); ii) observar las FZ y LZ durante la carrera al aire libre; y iii) analizar el efecto de la manipulación de la FZ en la economía de carrera monitorizada por un analizador de gases en función de las FZ encontradas en el análisis observacional. Ciento-sesenta corredores fueron analizados entre 8-14 km·h-1. El dispositivo Suunto Ambit2 concordó con el sistema de referencia en la medición de la FZ y la LZ [r=0.99 (0.99-1.00); Error Típico de la Estimación=0.58 zancadas∙min-1 y 0.02m]. Los corredores mantuvieron una FZ constante [Coeficiente de Variación (CV)=2.4%] aun cuando hubo variaciones en la velocidad (CV=6.8%), y dependieron de la LZ (CV=6.5%) durante las carreras al aire libre. Por último, los corredores mantuvieron un bajo coste de carrera con su FZ autoseleccionada (media=81.3 zancadas∙min-1), aunque un incremento hasta el 12% podría ser beneficioso cuando la velocidad varía sin detrimento en el coste de carrera.

 Abstract. This study aimed i) to study the agreement between a sports watch (Suunto Ambit2) with a  photoelectric device (Optogait) as a reference instrument on measuring stride frequencies (SF) and stride lengths (SL); ii) to observe the stride patterns during outdoor running; and iii) to analyse the effect of SF manipulations on running economy monitored by a gas analyser and based on the observational analysis. One hundred and sixty recreational runners were analysed at speeds between 8-14 km·h-1. The Suunto Ambit2 agreed with the reference system [r=0.99 (0.99-1.00); Typical Error of the Estimate=0.58 strides∙min-1 and 0.02m]. Runners tended to maintain SF constant [Coefficient of Variation (CV)=2.4%]) during variations in speed (CV=6.8%) while relied on SL (CV=6.5%) adjustments during outdoor running. Finally, runners seemed to maintain a low running cost with their auto-selected SF (average=81.3 strides∙min-1), but an increase of up to 12% could be benefit when speed changes, without running cost detriment.

Cerebral palsy (CP) football is undergoing a process of professionalisation which is improving the performance in this para-sport. This study aims to report the evolution of goal performance between the Seville 2019 and Salou 2022 IFCPF World Cups. Goals from eighty-eight matches over two consecutive IFCPF World Cups, in which the 16 best-ranked national teams took part, were analysed. The results revealed a decrease in the average of goals per match between championships (from 5.6 to 4.5 goals/match). Scored and received goals correlated to the teams’ final ranking position in both Seville 2019 and Salou 2022. The distribution of goals by halves and 15-minute periods, the probability of winning the match when a team scores first, the classification of goalkeepers and scoring players, and the type of goals (type of attack, the action leading to the goal, and the distance of the goal) in Salou 2022 in comparison to the Seville 2019 World Cup, a notable enhancement in the parity among the teams involved is discernible, alongside a rise in the competitive nature of CP football spanning across the aforementioned tournaments. This study also provides some practical applications to CP football coaches and practitioners as the importance to concede fewer goals rather than scoring more, the importance of scoring first, the importance of physical performance in the last minutes of the match, the importance of FT2 players as scorers rather than FT3 players or the most effective kind of attacks.
