Authors: Tan Kevin , Pagaduan Jeffrey , Janep Mandra , Nadzalan Ali Md 
Published: February 2022

Background and Study Aim. Inter-repetition rest pertains to a short period of rest between repetitions during strength training. Manipulating inter-repetition rest may influence fatigue accumulation, manifesting alteration in lifting mechanics. This study aimed to examine the effects of different inter-repetition rest protocols on joint velocity and ground reaction force during snatch exercise.
Material and Methods. Fifteen male (n=15) athletes participated in this study (age = 23.0 ±2.31 years; body weight = 65.32 ± 1.37 kg; height = 168.80 ± 5.64 cm; snatch one repetition maximum (1RM)/bodyweight = 0.78 ± 0.12), performing three sets of 5 repetitions at 85% 1 Repetition Maximum snatch with 10, 30, or 50 seconds of inter-repetition rest implemented randomly across three sessions. Ankle, knee, and hip kinematics and ground reaction force in the three protocols were used for comparison. The participants visited the exercise science laboratory for four sessions between 0800-1700 hrs. These sessions were separated by 72 hours.
Results. One-way repeated measure analysis of variances (ANOVA) showed a significant effect of inter-repetition rest on the maintenance of kinematic and kinetic variables. The ground reaction force for 10 seconds inter-repetition rest protocol showed a significant drop in force output across repetition (p = .037, p < 0.05).
Conclusions. The utilization of inter-repetition rest in snatch exercise may reduce neuromuscular fatigue across repetitions, maintaining consistent performance output. Specifically, the 50 second inter-repetition rest protocol reduced the negative effect of neuromuscular fatigue in the kinematic and kinetic variables during snatch exercise.

Abstract
An innovative biomimetic method has been developed to synthesize layered nanocomposite coatings using silica and sugar-derived carbon to mimic the formation of a natural seashell structure. The layered nanocomposites are fabricated through alternate coatings of condensed silica and sugar. Sugar-derived carbon is a cost-effective material as well as environmentally friendly. Pyrolysis of sugar will form polycyclic aromatic carbon sheets, i.e., carbon black. The resulting final nanocomposite coatings can survive temperatures of more than 1150 °C and potentially up to 1650 °C. These coatings have strong mechanical properties, with hardness of more than 11 GPa and elastic modulus of 120 GPa, which are 80% greater than those of pure silica. The layered coatings have many applications, such as shielding in the form of mechanical barriers, body armor, and space debris shields.

Aim. To perform a comparative assessment of the clinical and demographic characteristics of patients with non-ST elevation acute coronary syndrome (NSTE-ACS) and health care quality during the coronavirus disease 2019 (COVID-19) pandemic.Material and methods. Data obtained from medical records were used. Statistical processing was performed using the Statistica 10.0 software package. The analysis included patients with NSTE-ACS treated in 2020 (n=524) and 2019 (n=395). The group for further analysis consisted of patients with non-ST elevation myocardial infarction treated in 2020 (n=233) compared to 2019 (n=221).Results. An increase in the relative number of patients with unstable angina in the NSTE-ACS group was revealed. COVID-19 was verified in 5,5% of patients with NSTE-ACS. Of these, pneumonia was diagnosed in 10 (34,5%) patients, while 11 (37,9%) patients were transferred to pulmonary hospitals. The remaining 18 (62,1%) patients were discharged for outpatient treatment. Infected patients had a higher risk of in-hospital mortality according to the Global Registry of Acute Coronary Events (GRACE) score relative to general cohort of patients — 2,0 (1,0; 9,0) vs 1,0 (0,8; 3,0) (p=0,04). In addition, 215 (92,3%) patients underwent invasive coronary angiography, which is higher than in 2019 (78,7%) (p<0,001). An increase in revascularization prevalence in patients ≥75 years old was found (p=0,01).Conclusion. COVID-19 pandemic has led to a change in the clinical characteristics of patients, while not having a significant impact on the scope of endovascular interventions and health care quality for patients with NSTE-ACS in the emergency cardiology department.

Political and Legal Transformations of the Economy in the Concept of Cuban Socialism
Authors: Sergeev A. L. 
Published: February 2022

The paper is devoted to the main principles of the political and legal transformation of the economy in the doctrine of Cuban socialism. Cuban socialism itself is threefold: a socio-political system, a social movement, and a political and legal doctrine. The paper highlights the backbone importance of the economy as an object of political and legal transformations, focuses on the special flexibility of the corresponding concept, which made it possible, in a situation of limited natural resources and a large-scale economic blockade, to find many correct solutions to the tasks set. The author describes modern fundamental principles of economic construction that serve as a guideline for making both today’s political and economic decisions, and for determining the economic strategy of the future.An economic agenda in the political and legal doctrine of Cuban socialism at all times was of a system-forming nature, being one of the main components, relying on which this doctrine could explain the most complex political and legal processes of the present and illuminate the horizons of the future. The flexibility of economic thought inherent to the Cuban revolutionaries in synthesis with its deep value orientation, made it possible in the most difficult conditions of the economic blockade to make right decisions and confidently move forward. Due to this circumstance, Cuban socialism as a social system has shown amazing stability for more than six decades, changing and transforming in accordance with the requirements of the time and a rapidly changing world reality. At present, the economic doctrine of the Island of Freedom continues its modification and enrichment, finding more and more effective, comprehensive and systemic solutions in response to the global challenges of our time generated by the stormy waves of the 21st century.

Background: In our center, a breast conserving surgery (BCS) with immediate partial breast reconstruction using a latissimus dorsi mini flap (LDMF) is performed in women with a large tumor-to-breast-size ratio who declined mastectomy. We conducted a study to assess the oncological clearance and cosmetic outcomes following a BCS with immediate LDMF partial breast reconstruction in women with various breast pathologies. Methods: A cross-sectional study was conducted involving patients who underwent a BCS with immediate LDMF reconstruction between January 2016 and January 2021 in the hospital Kuala Lumpur, Malaysia. The demographic data, tumor characteristics, operative details and post-operative complications were documented. The histopathological reports were reviewed to determine the oncological clearance. Patient’s satisfaction on the cosmetic outcomes evaluated using a standard breast-Q questionnaire.Results: Thirty patients with various breast pathologies were recruited; invasive carcinoma (n=26, 86.7%), ductal carcinoma in-situ (DCIS) (n=1, 3.3%), phyllodes tumor (n=2, 6.7%), and dermatofibrosarcoma protuberans (n=1, 3.3%). The mean tumor size was 4.92 cm, giving the mean specimen weight of 224 g. Adequate oncological clearance was obtained in 96.7% of all cases. Seventeen of the patients (n=17, 56.6 %) were deeply satisfied and the remaining patients were satisfied (n=13, 43.3 %).Conclusions: In a stage II/III breast cancer, a BCS with immediate partial breast reconstruction using a LDMF can be safely performed with satisfactory cosmetic outcomes in women with a large tumor-to-breast-size ratio.

Background: The pandemic has imposed a prodigious limitation on surgical training and has disrupted hospital procedures, hindering continuing medical training. We have established an online classroom platform at our institute to pursue medical education, which has been a new experience for our residents and consultants.Method: Across-sectional survey was conducted in the department of general surgery to know the perception of surgical consultants/registrars and junior residents regarding online classes and conventional teaching methods. Survey was conducted online, wherein questionnaires related to online teaching were circulated to resident surgeons and consultants/registrars.Results: A total of 91 surgery residents and 26 surgical supervisors consisting of faculty members and registrars completed the survey. Junior residents provided encouraging feedback and supported online education in the COVID-19 period; they felt that courses were well discussed, except clinical case presentation. A total of 84.6% of surgery residents and all the surgical supervisors felt that lack of a functional operating theatre impeded their training. Majority of surgical supervisors (66%) were moderately satisfied by the quality of online training, whereas junior residents (79%) were very to extremely satisfied and most (83%) approved online classes in future. Majority of junior residents (90%) found the virtual platform very easy to use, opposite to surgery supervisors.Conclusions: Our study demonstrated that online education is a feasible way to train surgical residents. However, since surgical specialties depend heavily on practical experience, it is very important to implement new ways of acquiring practical skills.

Published: February 2022

Background: International travel and trade have been increasing at the greatest rate around the world and at the same time, several emerging and re-emerging public health emergencies are threatening the safety of people. The aim of the study was to assess the knowledge, risk perception, and protective behaviour of COVID-19 among the service providers at the major designated point of entry in Myanmar.Methods: The cross-sectional study was carried out among 216 service providers at Yangon international airport by using online telephone interviews during 2020. Participants with at least 6 months duration of working service (both private and public sectors) in their current area were included. Multiple logistic regression analysis was used to determine the factors influencing the protective behaviour of COVID-19. Results: All participants have heard about the COVID-19 pandemic and about (63%) also knew that coronavirus was the causal organism of the pandemic. Of 216 participants, only 18.5% had a low knowledge level. Overall good perception level towards COVID-19 was moderate to high. Majority (81.5%) reported good protective behaviour. Knowledge and perception of participants on COVID-19 did not influence the protective behaviour in this study, however, female (aOR=6.64, 95%CI=1.85, 22.61), and those who had long working hours (12 hours shift) (aOR=3.36, 95% CI=1.60, 7.05) had better protective behaviour on COVID-19. Conclusions: Although few service providers with limited knowledge and protective behaviour, most had good perception levels on COVID-19. Regular risk communication and awareness-raising activities were needed to increase the protective behaviours among the service providers at the airports.

Published: February 2022

Background: Financial access to health care has been sharply reduced in Africa following the introduction of cost recovery recommended by the Bamako initiative of 1987. Like in many countries in the world, in Cameroon, community-based organizations (CBO) which assist their members in the event of a financial crisis, death, funeral, birth, marriage, etc. added financial assistance in case of illness to alleviate this situation. This study aimed to determine models of financial assistance practiced by these organizations to rescue their members in event of illness.Method: Study was based on a sample of 150 CBO selected for convenience in 3 zones, including 50 in urban areas, 50 in semi-urban areas, and 50 in rural areas. Previously trained interviewers organized group discussions to collect data from these organizations using structured interview guide. The analysis of data collected was done manually.Results: The results show that 82.66% of organizations practice the "rescue quest model", 10.67% the "lump sum health assistance model", 2.67% "health tontine model", 2% "sickness deposit model", and 2% "subcontracting model" with an insurance company. The analysis shows that the "health tontine" and "sickness deposit" models are more forward-looking because they can make money available in time, before seeking care/before disease worsens.Conclusions: The systematization of these models could make it possible to mobilize funds on a community basis to extend the coverage of the financial risk linked to the disease to the populations of the informal and rural sector.

Background: Adolescence is considered a stressful period due to physical, psychological, sexual changes and is also influenced by maturity. Purpose of this study was to compare the prevalence of depression among XIth and XIIth class students of medical stream in urban schools of Ludhiana, Punjab.Methods: Present study was Cross-sectional study, conducted in in students, studying in urban schools of Jamalpur area of Ludhiana city. The investigator personally visited all the seven schools and went to both the class XI and XII and administered the study tool to each student of medical stream.Results: 253 students from medical stream of 11th and 12th class were considered for present study. Almost equal number of students in medical stream were studying in class XI and class XII, with slight over-representation (52.9%) of students in class XI. Majority (71.1%) of the students were females, and about half of the total students were of 16 years of age. Out of total students 84.6% students were suffering from depression with 17.8% having severe depression. Out of 134 students in Class XIth 81.3% had depression while 88.2% of 119 students in class XIIth were depressed, difference was not statistically significant. As the age increases the severity of depression in students also increases. At 15 years of age students suffering from moderate to severe depression is 31% whereas at 18 years of age 57% students were suffering from moderate to severe type of depression. There was a significant difference of prevalence of depression in between males and females, with females (89.4%) outnumbering males (72.6%).Conclusions: The overall prevalence of depression in our study was 84.6% and it is a prudent reminder of the extreme pressure the adolescent face in this particular age. Compared to other studies the percentage is alarmingly high.
