Authors: . Ismaningsih , Muawanah Siti
Published: March 2021

Urine incontinence is the loss of bladder control, or leaking urine. The current study aimed at providing a physiotherapy intervention such as adding neuromuscular taping to Kegel exercises for increasing the pelvic floor muscles. The study was conducted at the Wredha Khusnul Khotimah house in Pekanbaru. The study is an experimental research with a randomized pre- and post-test group design, and made a comparison between the two groups. The study compared the RUIS (Revised Urinary Incontinence Scale) scale value before and after the intervention. The study sample comprised of 20 middle-aged people with urine incontinence condition who were recommended neuromuscular taping in addition to their Kegel exercises for six weeks. Mann Whitney test found p-value < 0.05, so it could be concluded that there was a difference between the RUIS value before and after the intervention in both groups. The addition of neuromuscular taping to Kegel exercises is more effective than Kegel exercise alone for urine incontinence condition in middle-aged individuals.

Published: March 2021

Waste is a wordlwide problem including in Indonesia. The increasing amount of waste is caused by the increasing human population. Proper waste management must be applied to avoid detrimental health and environmental consequences. One way to manage waste is to design a device that could convert waste into electrical energy. This research aimed to provide a solution so that the volume of waste in Indonesia can be reduced and used as renewable energy. The methods used in this research were (1) identifying previous research on waste incineration and (2) designing a waste incinerator as appropriate technology and equipped with a system of utilizing the generated heat into electrical energy. The result of this research is the design of a device that can produce electricity from smoke and thereby reduce air pollution. Smoke from waste burning in a furnace was first filtered using a carbon cloth material to reduce air pollution. The heat from combustion was used to boil the water and change it into fumes above 100ºC. The steam produced had potential energy which was converted into kinetic energy through a turbine that can move the shaft to produce mechanical energy. Mechanical energy was then used to rotate the generator shaft that generated electric current and was then used to charge the battery. The battery power was then distributed for regualr use using a power converter.

Association between Knowledge and Practice of Breast Self-examination (BSE) for Raising Awareness in Women about Breast Cancer: A Literature Review
Authors: Miftalia Anugrah Putri Deka
Published: March 2021

Breast cancer (BC) is the most common type of cancers in women in many countries, ranking fifth in terms of cancer mortality among women. The problem is getting bigger because >70% of the patients of BC present at an advanced stage. There are many ways to prevent BC. Early examination or early detection is one of them, which helps in reducing the severity of BC. Several studies have shown that Breast Self-examination (BSE) is a simple, feasible way for the early detection of BC in low- and middle-income countries. There is evidence that women who correctly practice BSE on a monthly basis are more likely to detect a lump in the early stage of its development, and early diagnosis has been reported to influence early treatment. This review used a non-systematic method, sources were gathered using Google Scholar, Medline, Science Direct, and relevant articles published in English and Indonesian were accessed in full-text pdf format. Articles were analysed, extracted, synthesized and then the evidence was determined. All selected articles used a cross-sectional method with questionnaires as the instrument of data collection. The majority of study sample had unsatisfactory knowledge about BSE, and did not practice BSE frequently. The factors contributing to their unsatisfactory knowledge were: occupation, education, exposure to media information, access to medical personnel, and history of breast-related disease.

Potency of Solid Lipid Nanoparticle (SLN)-Modified Luteolin-based Polyethylene Glycol (PEG) on Allium fistulosum as Innovation Therapy of Malaria Falciparum
Authors: Martha Ariesaka Kiky , Taufiqurrahman Mudzakkir , Mirza Nuryady Moh
Published: March 2021

In 2013, 198 million cases of malaria were reported globally and 584,000 of them died. As much as 78% of cases occurred in children under five years of age. Indonesia is a has the second highest malaria incidence rate after India in the Asian region. Severe malaria can be characterized by the presence of severe anaemia, hyperparasitemia or cerebral malaria. Severe anaemia due to malaria or severe malaria anaemia (SMA) often occurs in children who suffer from falciparum malaria. SMA occurs due to a decrease in COX-2-PGE2, caused by phagocytosis of PfHz (Plasmodium falcyiparum-derived Hemozoin) by monocytes, macrophages and neutrophils. PfHz is a crystalline compound formed from the aggregation of heme hosts. Fe2+ is one of the constituents of heme, luteolin can bind Fe2+ so that the bond between luteolin and Fe2+ in heme prevents the formation of PfHz, so that severe anaemia can be prevented. Like other naturally occurring active compounds, luteolin has low bioavailability in the body so it is encapsulated using Solid Lipid Nanoparticles (SLN) and Polyethylene Glycol (PEG). SLN is useful for increasing the bioavailability of luteolin in the body, while PEG is useful for preventing the destruction of luteolin-SLN by RES. The modified construction process includes the following steps: (1) luteolin extraction from Allium fistulosum and (2) luteolin encapsulation using SLN-PEG. The potential dose to be administered orally to humans is 2.43–8.11 µg/kg body weight.

Children or Material Support: the Determination of Choice
Authors: Arkhangel’skiy Vladimir , Elizarov Valeriy , Dzhanayeva Natal’ya
Published: March 2021

The results of many studies show that in most families with the birth of a child, the material situation worsens. In families with several children, the standard of living is lower than in families with one child. The decrease in per capita income when a child appears in the family is due both to the fact that the total family income is divided among a larger number of family members, and to the fact that the income itself becomes lower, at least during the period of maternity leave. Having a child is a hindrance to improving family well-being. Despite this, some families are going to have a child (in the near future or somewhat later), but some are not going to. Having analyzed how some families differ from others, one can try to understand the determination of the choice between children and material wealth, and identify the factors that influence this choice. The analysis was carried out on the basis of the results of Rosstat surveys, sociological surveys of young people, as well as a number of regional studies (2003–2019). The analysis showed that those who are going to have another child, on average, have a smaller number of existing children, a higher importance of children, higher per capita incomes and a relatively higher assessment of the family's standard of living. Taking these factors into account when developing support measures for families with children will create preconditions for increasing the effectiveness of family and demographic policy in conditions of low and continuing decline in fertility.
The Gap Between Desired and Actual Level of Families Well–Being According to the Results Sociological and Demographic Married Couples Survey
Authors: Antonov Anatoly , Karpova Vera , Lyalikova Sofia
Published: March 2021

Based on a simultaneous husbands and wives survey, the article examines the relationship between the desired and actual level of per capita family income (along with housing conditions) in connection with the spouses’ socio-demographic characteristics. Most families with three and more children are characterized by low incomes, which require the introduction of material compensation as part of social policy. On the other hand, the task of family and demographic policy is to increase the current family need for two children, for which economic incentives are not enough. In this regard, noneconomic measures of influence are required; hence, the focus is on the analysis of value-motivational aspects of behavior, that is spousal self-assessment of desired and actual wellbeing. An increase in the degree of the gap between them first increases reproductive orientations and actual childbearing, and then lowers them. Socially significant is the critical value of the gap - the excess of the desired income over the actual up to three times, which determines the orientation of family behavior. Taking into account this empirical, well-grounded relationship is important from a practical point of view.

Sexo, igualdad, diversidad y leyes LGTBI
Authors: Cuesta Aguado Paz M. de la
Published: March 2021

Desde 2012 se ha generado una interesante actividad legislativa sobre el colectivo LGTBI. Todas estas leyes intentan garantizar, con finalidad didáctica y voluntarismo, la igualdad y evitar la violencia y discriminación que padece el colectivo. Sin embargo, una ley estatal se hace necesaria ya que las leyes autonómicas son insuficientes y pueden generar situaciones de conflicto normativo. A continuación, se analizan algunos problemas de técnica jurídica y se reflexiona sobre la necesidad y oportunidad de medidas específicas de acción positiva, pues, sin tales medidas, las leyes no dejan de ser meros catálogos de buenas intenciones, salvo por los ya referidos efectos didácticos. Estas medidas de acción positiva son necesarias para la mejora de vida del colectivo, que también tendrán efectos directos beneficiosos en otros, como el de mujeres, y, en general, indirectamente en toda la sociedad.

Inteligencia Artificial (y Administración Pública)
Authors: Criado J. Ignacio
Published: March 2021

Los algoritmos y la Inteligencia Artificial (IA) en el sector público se están adoptando en diferentes contextos. Conceptualmente, todavía no están claras las implicaciones de la IA y los algoritmos en las administraciones públicas. Sin embargo, diferentes organizaciones internacionales han definido una serie de principios éticos y cuestiones legales a tener en cuenta. Las instituciones de la Unión Europea se han convertido en el actor clave para guiar la adopción de IA, estableciendo las primeras líneas para las políticas públicas a nivel nacional. El Gobierno de España ha comenzado a desarrollar una estrategia en esa línea, si bien con unos responsables de políticas tecnológicas encargados de su implementación, que cuentan con sus propias percepciones y prioridades. Este artículo se inicia con las siguientes preguntas de carácter descriptivo y exploratorio: ¿Cómo están enmarcando ética y jurídicamente la IA los principales organismos internacionales? ¿Cuál es el marco de prioridades de la política de IA promovida por el Gobierno de España en relación con la Unión Europea? ¿Cuál es la percepción sobre la IA de los responsables de gestión de tecnologías (CIOs) en los ministerios? Para responder a estas preguntas, este trabajo se nutre de una revisión documental y de parte de los resultados de un cuestionario sobre las percepciones de los responsables de gestión de las tecnologías en los ministerios españoles. Nuestro análisis permite responder exploratoriamente las preguntas de investigación del estudio. Además, los resultados señalan algunas claves para diseñar políticas y estrategias de uso de la IA en diferentes contextos político-administrativos.
Crosstalk between Existential Phenomenological Psychotherapy and Neurological Science in Mood and Anxiety Disorders
Authors: Balogh Lehel , Tanaka Masaru , Török Nóra , Vécsei László , Taguchi Shigeru
Published: March 2021

Psychotherapy is a comprehensive biological treatment modifying complex underlying cognitive, emotional, behavioral, and regulatory responses in the brain, leading patients with mental illness to a new interpretation of the sense of self and others. Psychotherapy is an art of science integrated with psychology and/or philosophy. Neurological science studies the neurological basis of cognition, memory, and behavior as well as the impact of neurological damage and disease on the functions, and their treatment. Both psychotherapy and neurological science deal with the brain; nevertheless, they continue to stay polarized far. Existential phenomenological psychotherapy (EPP) has been in the forefront of meaning-centered counseling for almost a century. The phenomenological approach in psychotherapy originated in the works of Martin Heidegger, Ludwig Binswanger, Medard Boss and Viktor Frankl, and it has been committed to account for the existential possibilities and limitations of one’s life. EPP provides philosophically rich interpretations and empowers counseling techniques to assist mentally suffering individuals by finding meaning and purpose of life. The approach has proven to be effective in treating mood and anxiety disorders. This narrative review article demonstrates the development of EPP, the therapeutic methodology, evidence-based accounts of its curative techniques, current understanding of mood and anxiety disorders in neurological science, and a possible converging path to translate and integrate meaning-centered psychotherapy and neuroscience, concluding that the existential phenomenological psychotherapy potently plays a synergistic role with the currently prevailing medication-based approaches for the treatment of mood and anxiety disorders.

Published: March 2021

Current industrial trends bring new challenges in energy absorbing systems. Polymer materials as the traditional packaging material seem to be promising due to their low weight, structure and production price. Based on the review, the linear low-density polyethylene material was identified as the most promising material for absorbing impact energy. The current paper addresses the identification of the material parameters and the development of a Constitutive material model to be used in future design by virtual prototyping. The paper deals with the experimental measurement of the stress-strain relations of the linear low-density polyethylene under static and dynamic loading. The quasi-static measurement is realized in two perpendicular principal directions and is supplemented by a test measurement in the 45 degrees direction, i.e. exactly between the principal directions. The quasi-static stress-strain curves are analyzed as an initial step for dynamic strain rate dependent material behavior. The dynamic response is tested in the drop tower using a spherical impactor hitting the flat material multi-layered specimen at two different energy levels. The strain rate dependent material model is identified by optimizing the static material response obtained in the dynamic experiments. The material model is validated by the virtual reconstruction of the experiments and by comparing the numerical results to the experimental ones.
Reinforcement Learning for Electric Vehicle Charging using Dueling Neural Networks
Authors: Gokhale Gargya , Claessens Bert , Develder Chris
Published: March 2021

We consider the problem of coordinating the charging of an entire fleet of electric vehicles (EV), using a model-free approach, i.e. purely data-driven reinforcement learning (RL). The objective of the RL-based control is to optimize charging actions, while fulfilling all EV charging constraints (e.g. timely completion of the charging). In particular, we focus on batch-mode learning and adopt fitted Q-iteration (FQI). A core component in FQI is approximating the Q-function using a regression technique, from which the policy is derived. Recently, a dueling neural networks architecture was proposed and shown to lead to better policy evaluation in the presence of many similar-valued actions, as applied in a computer game context. The main research contributions of the current paper are that (i)we develop a dueling neural networks approach for the setting of joint coordination of an entire EV fleet, and (ii)we evaluate its performance and compare it to an all-knowing benchmark and an FQI approach using EXTRA trees regression technique, a popular approach currently discussed in EV related works. We present a case study where RL agents are trained with an epsilon-greedy approach for different objectives, (a)cost minimization, and (b)maximization of self-consumption of local renewable energy sources. Our results indicate that RL agents achieve significant cost reductions (70--80%) compared to a business-as-usual scenario without smart charging. Comparing the dueling neural networks regression to EXTRA trees indicates that for our case study's EV fleet parameters and training scenario, the EXTRA trees-based agents achieve higher performance in terms of both lower costs (or higher self-consumption) and stronger robustness, i.e. less variation among trained agents. This suggests that adopting dueling neural networks in this EV setting is not particularly beneficial as opposed to the Atari game context from where this idea originated.

Myxococcus xanthus as a Model Organism for Peptidoglycan Assembly and Bacterial Morphogenesis
Authors: Zhang Huan , Venkatesan Srutha , Nan Beiyan
Published: March 2021

A fundamental question in biology is how cell shapes are genetically encoded and enzymatically generated. Prevalent shapes among walled bacteria include spheres and rods. These shapes are chiefly determined by the peptidoglycan (PG) cell wall. Bacterial division results in two daughter cells, whose shapes are predetermined by the mother. This makes it difficult to explore the origin of cell shapes in healthy bacteria. In this review, we argue that the Gram-negative bacterium Myxococcus xanthus is an ideal model for understanding PG assembly and bacterial morphogenesis because it forms rods and spheres at different life stages. Rod-shaped vegetative cells of M. xanthus can thoroughly degrade their PG and form spherical spores. As these spores germinate, cells rebuild their PG and reestablish rod shape without preexisting templates. Such a unique sphere-to-rod transition provides a rare opportunity to visualize de novo PG assembly and rod-like morphogenesis in a well-established model organism.
Effects of Polyphenols in Tea (Camellia Sinensis sp.) on Modulation of Gut Microbiota in Human Trials and Animal Studies
Authors: Khairudin Mus Azza Suhana , Mhd Jalil Abbe Maleyki , Hussin Napisah
Published: March 2021

A diet high in polyphenols is associated with a diversified gut microbiome. Tea is the second most consumed beverage in the world, after water. The health benefits of tea might be attributed to the presence of polyphenol compounds such as catechins, theaflavins, tannins, and flavonoids. Although many studies are on tea, little is known of its effects on trillions of gut microbiota. Hence, this review is aimed at systematically studying the effect of tea polyphenols on the stimulation or suppression of gut microbiota in humans and animals. It was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Articles were retrieved from PubMed and Scopus databases, and data were extracted from 6 human trials and 15 animal studies. Overall, huge variations were observed in terms of microbiota composition between humans and animals. A more consistent pattern of diversified microbiota was observed in animal studies. Tea alleviated the gut microbiota imbalance caused by high-fat diet-induced obesity, diabetes, and ultraviolet-induced damage. Overall changes in microbiota composition measured by beta diversity analysis showed that tea had shifted the microbiota from the pattern seen in animals that received tea-free intervention. In humans, the prebiotic-like effect was observed towards gut microbiota, but these results appear in lower-quality studies. Beta diversity in human microbiota remains intact despite tea intervention; supplementation with different teas affected different types of bacterial taxa in the gut. These studies suggest that tea polyphenols may have a prebiotic effect in disease-induced animals and in a limited number of human interventions. Further intervention is needed to identify the mechanisms of action underlying the effects of tea on gut microbiota.

Nickel-based ethylene polymerization catalysts have unique features, being able to produce macromolecules with a variable content of branches, resulting in polymers ranging from semicrystalline plastics to elastomers to hyperbranched amorphous waxes and oils. In addition to Brookhart's α-diimine catalysts, iminopyridine Ni(II) complexes are among the most investigated systems. We report that Ni(II) complexes bearing aryliminopyridine ligands with bulky substituents both at the imino moiety and in the 6-position of pyridine afford either hyperbranched low molecular weight polyethylene oils or prevailingly linear crystalline polyethylenes or both depending on the ligand structure and the reaction conditions. The formation of multiple active species in situ is suggested by analysis of the post-polymerization catalyst residues, showing the partial reduction of the imino function. Some related arylaminopyridine Ni(II) complexes were also synthesized and tested, showing a peculiar behavior, i.e. the number of branches of the produced polyethylenes increases while ethylene pressure increases.

Abstract Introduction: COVID-19 has a relationship with patients’ demographic characteristics as well as their underlying diseases. This research has been conducted to evaluate factors' effect on Covid-19 patient's hospitalization rate and period in Hormozgan, Iran. Materials and Methods: The inclusion criteria of this retrospective study included all patients diagnosed as COVID-19 Patients after PCR who were referred to Covid-19 hospitals from February 2020 to June 2020 in Hormozgan province, Iran. After the completion of the consent form and observing ethical principles, 3480 patients' information was collected through the interview by Medical care monitoring center unit experts. The checklist was designed according to COVID-19 guidelines and approved by the World Health Organization and Iran Ministry of Health and Medical Education. The studied variables included gender, age, patients’ residence place, smoking history and medications use history, pregnancy, referral type to hospital, contact history with COVID-19 patients, early symptoms, gastrointestinal symptoms, intubation, Po2 level, history of cancer, chronic liver diseases, diabetes, chronic blood diseases, HIV/AIDS, acquired or congenital immunodeficiency, cardiovascular diseases, chronic kidney diseases, dialysis status, asthma and other chronic lung diseases, and chronic neurological disorders. These data were analyzed using descriptive (average-standard deviation-percentage) and analytical (including Chi-square, t-test, and regression tests) statistics with SPSS Ver.23 software. Results: In this study, 3480 COVID-19 patients including 1852 male patients (53.20%) with a median age of 43.11±21.72 and 1628 female patients (46/80%) with a median age of 44.86±22.40. The median age of men was significantly lower than the women's median age (P= 0.02). The duration of hospitalization of male and female patients was reported 2.64±4.14 and 2.76±4.297, respectively which was not statistically significant. The death rate of patients in our study was 6.6%. Conclusion: The results of this study also showed that the hospitalization period of HIV-positive patients and patients with cardiovascular and pulmonary diseases is much longer than other people, which imposes many human and financial costs on the country's health care system. Therefore, to maintain individual health and help improve the critical condition of the virus, it is better to develop and apply stricter protocols to prevent further outbreaks of the disease and check underlying diseases of people suspected to have Covid-19. These results can improve health care system planning and improving medical services presented to covid-19 patients.

Objective: The aim of this current paper was to evaluate effect of inclusion Sargassum sp. in the ration on meat nutrient content, meat fatty acid profile and waste production of New Zealand White (NZW) rabbit.

Methods: Twenty four NZW rabbit (70-80 d old) with initial body weight 1736 ± 50 g were randomly allocated in to three treatments. The treatments were: T1 basal feed, T2 inclusion of 4% Sargassum sp. in the basal feed and T3 inclusion of 8% Sargassum sp. in the basal feed.

Results: Results of this experiment showed that inclusion of Sargassum sp. in the ration gave no effect (P>0.05) on the moisture, ash, crude protein content of Longisimus dorsi (LD) muscle, carcass percentage, warm carcass weight, cold carcass weight and waste production. However, the treatment was significantly (P<0.05) decreasing fat content of LD muscle. Fatty acids profile of all treatments was relatively same.

Conclusions: Utilization of Sargassum sp. in the rabbit ration up to 8% has no impact on the carcass production, protein, ash, and meat water content, and the waste production. Even the inclusion of Sargassum sp. the ration at level of 4% can reduce the fat content of rabbit meat. Thus, based on the observed parameters Sargassum sp. can be used to substitute rabbit feed up to a level of 8%.

Background:

Investigations into reimbursement trends for primary and revision arthroplasty procedures have demonstrated a steady decline over the past several years. Revision total hip arthroplasty (rTHA) due to infection (rTHA-I) has been associated with higher resource utilization and complexity, but long-term inflation-adjusted data have yet to be compared between rTHA-I and rTHA due to aseptic complications (rTHA-A). The present study was performed to analyze temporal reimbursement trends regarding rTHA-I procedures compared with those for rTHA-A procedures.

Methods:

The Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule Look-Up Tool was used to extract Medicare reimbursements associated with 1-stage and 2-stage rTHA-I as well as 1-stage rTHA-A procedures from 2002 to 2019. Current Procedural Terminology (CPT) codes for rTHA were grouped according to the American Academy of Orthopaedic Surgeons coding reference guide. Monetary values were adjusted for inflation using the consumer price index (U.S. Bureau of Labor Statistics; reported as 2019 U.S. dollars) and used to calculate the cumulative and average annual percent changes in reimbursement.

Results:

Following inflation adjustment, the physician fee reimbursement for rTHA-A decreased by a mean [and standard deviation] of 27.26% ± 3.57% (from $2,209.11 in 2002 to $1,603.20 in 2019) for femoral component revision, 27.41% ± 3.57% (from $2,130.55 to $1,542.91) for acetabular component revision, and 27.50% ± 2.56% (from $2,775.53 to $2,007.61) for both-component revision. Similarly, for a 2-stage rTHA-I, the mean reimbursement declined by 18.74% ± 3.87% (from $2,063.36 in 2002 to $1,673.36 in 2019) and 24.45% ± 3.69% (from $2,328.79 to $1,755.45) for the explantation and reimplantation stages, respectively. The total decline in physician fee reimbursement for rTHA-I ($1,020.64 ± $233.72) was significantly greater than that for rTHA-A ($580.72 ± $107.22; p < 0.00001).

Conclusions:

Our study demonstrated a consistent devaluation of both rTHA-I and rTHA-A procedures from 2002 to 2019, with a larger deficit seen for rTHA-I. A continuation of this trend could create substantial disincentives for physicians to perform such procedures and limit access to care at the population level.

Delayed Displacement of a Subtle Sacral Insufficiency Fracture Unmasking Lumbopelvic Instability
Authors: Campbell Sean T. , Firoozabadi Reza
Published: March 2021

Case:

There is limited literature reporting on sacral insufficiency fractures as a cause of lumbopelvic instability. We describe the presentation, treatment, and clinical outcome with a 2-year follow-up of a woman who sustained a low-energy spinopelvic dissociation diagnosed with magnetic resonance imaging. There was significant delayed displacement, and the patient was treated surgically with percutaneous iliosacral and trans-sacral screws.

Conclusion:

U-type sacral insufficiency fractures may be subtle on advanced imaging and must be followed closely if nonoperative treatment is chosen. These patients may require surgical intervention. Iliosacral screws and lumbopelvic fixation are treatment options, each with advantages and disadvantages.
