Published: February 2023

Background
The past 2 decades have seen rapid development in the use of robots for rehabilitation. Research on rehabilitation robots involves interdisciplinary activities, making it a great challenge to obtain comprehensive insights in this research field.

Objective
We performed a bibliometric study to understand the characteristics of research on rehabilitation robots and emerging trends in this field in the last 2 decades.

Methods
Reports on the topic of rehabilitation robots published from January 1, 2001, to December 31, 2020, were retrieved from the Web of Science Core Collection on July 28, 2022. Document types were limited to “article” and “meeting” (excluding the “review” type), to ensure that our analysis of the evolution over time of this research had high validity. We used CiteSpace to conduct a co-occurrence and co-citation analysis and to visualize the characteristics of this research field and emerging trends. Landmark publications were identified using metrics such as betweenness centrality and burst strength.

Results
Through data retrieval, cleaning, and deduplication, we retrieved 9287 publications and 110,619 references cited in these publications that were on the topic of rehabilitation robots and were published between 2001 and 2020. Results of the Mann-Kendall test indicated that the numbers of both publications (P<.001; St=175.0) and citations (P<.001; St=188.0) related to rehabilitation robots exhibited a significantly increasing yearly trend. The co-occurrence results revealed 120 categories connected with research on rehabilitation robots; we used these categories to determine research relationships. The co-citation results identified 169 co-citation clusters characterizing this research field and emerging trends in it. The most prominent label was “soft robotic technology” (the burst strength was 79.07), which has become a topic of great interest in rehabilitative recovery for both the upper and lower limbs. Additionally, task-oriented upper-limb training, control strategies for robot-assisted lower limb rehabilitation, and power in exoskeleton robots were topics of great interest in current research.

Conclusions
Our work provides insights into research on rehabilitation robots, including its characteristics and emerging trends during the last 2 decades, providing a comprehensive understanding of this research field.
En respuesta a: gliflozinas en el manejo de la enfermedad cardiovascular
Authors: Rico-Fontalvo Jorge , Morales-Portillo Cristóbal , Bohórquez-Rivero José 
Published: February 2023

Hemos leído con gran interés el artículo de Braunwald E,1 titulado "Gliflozins in the management of cardiovascular disease" publicado recientemente en New England Journal of Medicine, donde el autor hace una excelente revisión de los inhibidores de SGLT2 (iSGLT2) y sus efectos a nivel cardiovascular; sin embargo, consideramos relevante aclarar ciertos puntos al respecto.
En Particular, cuando se mencionan los mecanismos de acción de estos fármacos a nivel renal, solo se incluyen los mecanismos hemodinámicos (natriuresis, disminución de la presión intraglomerular, glucosuria, restablecimiento de la retroalimentación túbulo-glomerular, entre otros) que, si bien son muy importantes, cabe agregar que existen mecanismos antiinflamatorios intrarrenales directos dados por la disminución de la glucotoxicidad renal (disminución de especies reactivas de oxígeno, moléculas proinflamatorias, miofibroblastos profibróticos, entre otros). Los efectos antiinflamatorios intrarrenales pueden explicar los efectos de estos fármacos a medio y largo plazo en términos de nefroprotección. En otras palabras, la inflamación juega un papel muy importante en el desarrollo de la enfermedad renal y los iSGLT2 tienen un impacto en estas vías, de ahí la importancia de abordar dichos mecanismos2.
La revisión también menciona que la dapagliflozina y la canaglifozina cuentan con la aprobación de la FDA para reducir el riesgo de enfermedad renal crónica en etapa terminal. Aclaramos que por el momento solo la dapagliflozina es la que cuenta con esta aprobación en base a la evidencia del estudio DAPA CKD3. Canagliflozina en su estudio CREDENCE solo incluyó pacientes con enfermedad renal diabética, por lo tanto, no tiene evidencia en enfermedad renal crónica no diabética4.

The use of illegal and hazardous preservative agents such as formalin by traditional fishermen and trader has become a problem in Indonesia. Â In this research, instant extract powder of green tea and black tea were used as natural preservatives for fish. Both substances are known for their anti-bacterial and anti-oxidative activities due to the presence of various types of polyphenols, particularly the catechin groups. The tea extract powder was produced Â by drying Â using a spray drying device. The two different tea extract powders were tested separately, and in combination. The tests were done by dipping pieces of fresh indian mackerel fish (Rastrelliger kanagurta), also known locally as kembung banjar, in the solution containing the tea extract. The microbial tests were done using total plate count (TPC) method. The result showed that instant green and black tea extracts was capable in suppressing bacterial growth in fish. When the two substances were mixed together, the preservation activities were found to be stronger than if they were used separately. In addition, histamine and total volatile base nitrogen (TVB-N) tests which are regularly used to test the freshness of fish also showed substantial improvement in the quality of the fish sample. The sensory tests also showed that the extracts were capable of improving the freshness of the fish sample.Â

Authors: Sriyadi Bambang 
Published: February 2023

As an effort to conserve tea clone accessions of first generation from genetic erosion, arrangement germplasm in one particular block/area to be easily monitored and managed, is needed. Ideally, tea germplasm collection should consist of a few clone accession number but high genetic variability. To select representative clones that will be conserved in new germplasm collection, leaves morphology similarity has been analysed by cluster analysis using average method. The results showed that by using leaves morphology parameter, from 50 tea clone accession of first generation coming from several tea plantations, it could be reduced into 25 clone accessions from seven clusters, which each has high similarity. The first cluster with 60% similarity could reduced accession from 15 to 6 clone. The second with 74,8% similarity from 25 to 13 clones. The third with 74,8% similarity, from 4 to 2 clones. The fourth with 61,3% similarity, and seventh with 82,1% similarity, both could reduce from 2 clones to 1 clone. To design a tea germplasm collection with 50 accessions of genetic variability, it could represented by 25 clones with low similarity, i.e PG 3, KP 1, Skm 18, Cin 69, Cin 67 dan Cin 58 as the first cluster representatives, Mel 101, PG 4, Pam 15, PG 5,Â PG 11, GP 2, BD 13, SA 49, Cin 66, Mal 16, Bks 6 and Sin 5 the second cluster representatives;Â Â Mel 108 and Cin 13 as the third cluster representatives; and Cin 15, Cip 37, GH 5, as well as GP 4 as the fourth, the fifth, and the sixth representatives, respectively.

The effectiveness application of compound fertilizer NPK (27%:6%:10%) to increase Â tea shoots had been tested in Experimental Garden of Research Institute for Tea and Cinchona Gambung, Bandung, West Java, from January 2006 to March 2007. ExperiÂ­mental design used was randomized block design with 6 treatments with five replication. The plot sizes were 20 x 20 m = 400 m2/plot. The tea clone tesÂ­ted was GMB 7. The appliÂ­cation of compound fertilizer NPK (27%:6%:10%) were twice a year (50%-50%) and conventional fertlization were 4 times a year (20%-30%-20%-30%). The composition ofÂ treatment was as follows: (A) 500 kg, (B) 600 kg, (C) 700 kg, (D) 800 kg/ha/year, and (E) conventional fertilizer recommended dosage of the Research InstituteÂ for Tea and Cinchona Gambung (480 kg urea + 357 kg ZA + 260 kg SP 36 + 300 kg KCl + 278 kgÂ kieserit/ha/year), and (F) control (no fertilizer treatment). ParametersÂ observed were: 1. soil and leaf analysis at before and after treatment, 2. weighting the potential and the yield components each time of plucking, and 3. technoeconomic analysis. The results showed that: statistical analysis of the components as well as potential yield, and nutrient analysis (N, P, K, Mg and Zn) of the mother leaves of GMB 7 clones and the soil demonÂ­strated the significantly differences among the treatments of all the various doses of compound fertilizer NPK and conventional fertilizer application to control (no fertilizer treatment). Meanwhile, there were no significantly differences among the result of Â the doses of compound fertilizer NPK, to the conventional fertilizer applications. FurtherÂ­more, dose of compound fertilizer NPK (27%:6%:10%) for producÂ­tive tea plant was recommendated at 700 kg/ha rate and was equivalent to 189 kg N/ha/year or 63% of the dose of conventional fertilizer, but could provide equivalent result to conventional fertilizer application, and not only could save the buying cost of conventional fertilizerÂ (urea, ZA, TSP/SP-36, KCl / MOP and kieserit) but also the cost of application cost in the field.

INTRODUCTION: The existing multiple factors of the ship’s environment, together with the climatic conditions of navigation, have a long and complex effect on the body of seamen. As a result, they often cause significant changes in the body. In turn, such changes can cause the emergence and development of many diseases.OBJECTIVE: To analyze the morbidity of trawl fleet fishermen working in different climatic regions, possible factors contributing to the occurrence of diseases, to develop recommendations for reducing diseases with disability of workers.MATERIALS AND METHODS: The morbidity of fishermen of the Arkhangelsk trawl fleet for the same period when working in the fishery in different climatogeographic regions was studied. 464 people of 4 crews of large freezing fishing trawlers aged 25–49 years (average age 41.8±9.5 years) and work experience from 3 to 10 years were under monitoring. The fishing area is the Norwegian Sea (northern climate zone, crew 237 people) and the Moorish Economic Zone (southern region, crew 217 people). The duration of the works ranged from 168 to 185 days. 10 voyage reports from on-board logbooks (5 times in each of the climatic regions) were used as sources of information on morbidity. Statistics: The McNemar criterion was used for comparative analysis between frequency indicators, and the MannWhitney criterion was used for absolute averages. The statistical significance level p<0.05 was regarded as proven statistically significant differences between the compared indicators.RESULTS: The morbidity of seafarers, according to the initial appeals, had statistically significant differences when working in different climatogeographic regions. The frequency of cases of temporary disability for people working in tropical regions turned out to be much higher in comparison with the northern ones. At the same time, the average duration of the disease in the absolute majority of nosological forms (except for skin and subcutaneous tissue diseases) had no statistically significant differences between the groups of sailors.DISCUSSION: Territorial features of fishing produce the characteristic of morbidity. Among them, the greatest contribution to the occurrence of diseases are frequent international contacts, peculiarities of processing of harvested fish, tension of adaptation mechanisms due to work in unusual conditions combined with hard work. The identified causes of morbidity among trawl fleet fishermen require the development of special measures to level them, prevent the development of chronic diseases.CONCLUSION: Is made about the need for constant monitoring of seafarers to determine adaptive changes during the voyage period and during the readaptation of the crew to coastal conditions. Within the framework of the medical support system for water transport workers, it is necessary to take into account the adverse factors of the professional environment in order to create high-quality and safe working conditions.

INTRODUCTION: The period of the current COVID-19 pandemic is associated with a prolonged situation of uncertainty; in the preference of styles and strategies for overcoming the intellectual and personal potential of a person is presented in the unity of the processes of cognitive evaluation, experience and choice of ways to solve a problem (stressful) situation.OBJECTIVE: To study the interrelationships of decision-making style as a reflection of individual differences in coping with uncertainty and emotional creativity as a factor of self-realization in young people who have had COVID19 infection.MATERIALS AND METHODS: We examined 100 convalescents aged 18.2±2.25 years, including 50 men (Group M) and 50 women (Group G) (the age difference between the groups is not significant). The main transferred clinical forms of COVID-19 infection were the inapparent form — 42.0% (group M — 32 people, group G — 10 people), acute respiratory viral infection — 56.0% (group M — 17 people, group G — 39 people) according to the Russian versions of the Melbourne Decision Making Questionnaire (MDMQ) and the Emotional Creativity Inventory (ECI).RESULTS: In both groups of examined individuals after COVID-19 infection with all clinical forms of the disease, the strategy of «vigilance», considered as productive, is of the greatest importance in the decision-making process; unproductive strategies are not expressed, which is important for the subsequent medical and psychological support of convalescents.DISCUSSION: In both groups of examined individuals after suffering COVID-19 infection in all clinical forms of the disease, the «vigilance» strategy, considered as productive, is of the greatest importance in the decision-making process; unproductive strategies are not expressed, which is important for the subsequent medical and psychological support of convalescents. It is noted that the interaction between the factors of emotional creativity is expressed not only in an increase in creativity when high values coincide on two or more faces, but also in the fact that low values of one component can be compensated by high values of another.CONCLUSION: It is noted that the interaction between the factors of emotional creativity is expressed not only in an increase in creativity when high values coincide on two or more sides, but also in the fact that low values of one component can be compensated by high values of the other.

Published: February 2023

Abstract

Study aim: The aim of the study was to determine the effects of body weight loss on the levels of somatic features and peak power of senior Greco-Roman wrestlers from the Polish national team.

Material and methods: The study included 14 males, i.e. 7 wrestlers reducing their body weight and 7 wrestlers not changing their body weight. Seven days prior to a competition, the study participants began a 5-day process of losing body weight. The process involved reducing caloric intake from 3460 ± 683.1 kcal to 2160.0 ± 423.5 kcal per day.

Results: Over the period of 5 days, the participants reduced their body weight by 3.1 ± 0.7 kg (p < 0.001). There occurred a decrease in the value of endomorphy (p < 0.01) and mesomorphy (p < 0.05) and an increase in the value of ectomorphy (p < 0.001). Peak power did not change (1296 ± 100.9 W on day 5 of the examination), nor did relative peak power (19.9 ± 1.1W/kg).

Conclusions: In wrestlers 5-day rapid weight loss protocol may result in decrease of body circumferences and consecutive changes in somatic type without concurrent loss in lower-limb peak power.
