Authors: Sutyawan I Wayan Eka , Surasmiati Ni Made Ayu , Agrasidi Putu Anindya , Dwianggita Priscilla , Anggara Stephanus Anggara
Published: December 2023

Highlights:

This is the first systematic review investigating thrombocytopenia and its association with retinopathy of prematurity
The findings suggest that thrombocytopenia could serve as a potential clinical biomarker for screening ROP, considering its quick, affordable, and widespread availability for examination purposes.

 
Abstract
Retinopathy of prematurity (ROP) is the leading cause of childhood blindness and occurs due to the underdevelopment of retinal blood vessels in premature infants. Platelets are essential in the regulation of angiogenesis. Hence, thrombocytopenia might aid in the progression of ROP. This systematic review aims to look into the relationship between thrombocytopenia and retinopathy of prematurity. The PubMed and Cochrane Library databases were accessed to include retrospective case-control and cross-sectional studies, following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). In our review, 9 records were analyzed. All research was done in the period between 2017 and 2022 . Seven studies have reported the prevalence of thrombocytopenia in infants with retinopathy of prematurity (ROP), ranging from 18.37% to 71%. In preterm children without ROP, the occurrence of thrombocytopenia is between 5.71% and 21%. Seven studies have significantly identified thrombocytopenia as a risk factor for ROP, with the Odd Ratio (OR) for thrombocytopenia ranging from 2.8 to 6.69 . Therefore, thrombocytopenia in premature infants could be thought of as a potential clinical biomarker for Type-1 ROP screening. Additionally, this discovery implied that thrombocytopenia can contribute to the pathophysiology of ROP. The crucial platelet count threshold in ROP requires additional investigations.

Highlights:1. Elastase, hyaluronidase, and tyrosinase can all be inhibited by temulawak extract.2. Temulawak extract has strong anti-aging ability and can be used as a candidate for cosmetic applications.
 
AbstractThe process of aging is the gradual loss of a tissue's capacity to heal and maintain normal or physiological form and function. Elastase, hyaluronidase, and tyrosinase are the enzymes that contribute to skin aging. The anti-aging effect is connected to the inhibition of these enzymes' activity. Many medicinal plants with active metabolite have been utilized extensively to treat aging. Active compounds of temulawak (Curcuma xanthorrhiza L.) such as phenolic, curcuminoid and xanthorrhizol have potential as antiaging. This study aims to determine whether temulawak extract (TE), a potential candidate for cosmeceutical agent, has anti-aging characteristics by inhibiting the elastase, hyaluronidase, and tyrosinase enzymes. TE was processedxby PT FAST. Stock solution of TE was made by dissolving 20 mg of extract with 1 ml of DMSO 100%, the stock solution was then diluted to achieve the concentrations level 31.25 - 1000 μg/ml working solution of TE. The antiaging activity assays were carried out at PT Aretha Medika Utama. In vitro antiaging assay of TE includes elastase, hyaluronidase, and tyrosinase enzyme inhibition at 7 level of various concentrations of 2.08-66.67 μg/ml for anti-elastase assay, 5.21-166.67 μg/ml for anti-hyaluronidase assay, and 3.125-100 μg/ml for anti-tyrosinase assay with three replications. SPSS software was used to conduct the statistical analysis (p<0,05 is considered significant). TE exhibited highest inhibition percentage of 82.72%, 89.41%, and 94.17% for anti-tyrosinase, anti-elastase, and anti-hyaluronidase, respectively. The median inhibitory concentration (IC50) for elastase inhibitory activity was 10.66 μg/ml, hyaluronidase 70.39 μg/ml, and tyrosinase 55.87 μg/ml. According to this study, TE can be used as cosmeceu

Authors: Farhan Mhnd
Published: December 2023

This article compares the performance of two modulation techniques—quadrature phase shift keying (QPSK) and M-ary quadrature amplitude modulation (M-QAM) with M=8, 16, 32, and 64—in a coded orthogonal frequency division multiplexing system. As an error-correcting code, convolutional technology is employed. A vehicular channel with additive white gaussian noise (AWGN) is utilized for communication. According to simulation data, for QPSK and M-QAM, a coded orthogonal frequency division multiplexing system performs better than an uncoded one. Additionally, the system performs better with QPSK than it does with M-QAM. Additionally, when M rises, the performance declines.

Published: December 2023

Background: The National Health Insurance or Jaminan Kesehatan Nasional (JKN) program is one of the steps taken by the Indonesian government in developing Universal Health Coverage (UHC). However, increased participation in the National Health Insurance is not followed by an increase in met needs for healthcare services.
Aims: This study aimed to examine the effect of participation in the National Health Insurance on unmet needs for healthcare services in poor and non-poor population groups.
Methods: This study used data from the 2018 National Socio-Economic Survey/ Survei Sosial Ekonomi Nasional (SUSENAS) and Village Potential Survey/ Survei Potensi Desa (PODES). Data were processed using binary logistic model analysis to identify the effect of participation in the National Health Insurance on the unmet needs for healthcare services.
Results: Participation in the National Health Insurance, including beneficiary program for poor groups could reduce the risks of unmet needs for healthcare services by 7.7%, while non-beneficiary program could reduce the risks of unmet needs for health services for non-poor groups by 10.4%.
Conclusion: Both beneficiaries and non-beneficiaries affect the unmet needs for health services for both poor and non-poor groups. However, the non-beneficiary program is more elastic than beneficiary program to fulfill needs for both sample groups.

Authors: Dewi Ervin Dyah Ayu Masita , Christianto Hwian
Published: December 2023

Background: Not all public approval to receive COVID-19 vaccination is based on understanding the right information, which is considered insufficient motivation. It is also related to inadequate government policies.
Aims: This study was to identify the implementation of informed consent in COVID-19 vaccination, in terms of the autonomy of the vaccine recipients, so that the necessary policy could be recommended.
Methods: The research was conducted at Surabaya in June-December 2021 with descriptive qualitative methods through in-depth interviews with five vaccinators and five vaccine recipients using purposive sampling. Data were analyzed from interview transcripts by coding, making categories and themes, and then compared to relevant references.
Results: The results showed that 60% of the implementation of the COVID-19 vaccination informed consent was inadequate. It was found that incomplete information disclosure is often not even given information, and vaccinations are carried out without a signature of informed consent. These findings suggest that respect for the autonomy of COVID-19 vaccine recipients has not been made.
Conclusion: Inadequate respect for the autonomy of vaccine recipients risks causing a medical conflict in the future if there are unexpected effects. Thus, the government must make standard informed consent procedures for COVID-19 vaccination and collaborate with the local government.
Keywords: Covid-19 vaccination, informed consent, information disclosure, respect for autonomy

This research aimed to explore the factors that promote and hinder youth’s mental health during the pandemic. A total of 151 participants (79% female) aged 18-30 years completed an online survey included open-ended questions about their friendship experience. Thematic analysis using an inductive approach yielded several themes. Social support, communication, quality time, openness, emotional bonds, empathy, guidance, and advice were identified as relational aspects that promote mental health. Lack of social support, ineffective communication, emotional and physical distance, and conflicts were identified as relational aspects hindering mental health. Toxic relationship tendencies, such as judgment and imposition, were also considered detrimental to mental health. Furthermore, personal aspects such as integrity in friendship were perceived as positive for mental health, while certain negative personality traits, negative feelings, and thoughts were seen as harmful. The way young people define supportive friends versus "toxic" friends can differ across contexts other than pandemic.

Authors: Devani Pricilia , Hasanah Alfiah
Published: December 2023

ABSTRACT
The aim of this study was to examine the effect of above-average educational attainment of Muslim households on the amount of alms given by the household. This study uses panel data from the Indonesian Family Life Survey Wave 4 and Wave 5, with a sample consisting of Muslim household heads with a history of secondary education (SMA/SMK) and higher education. The data were processed and analysed using the fixed effects regression method using STATA software version 17. The results of this study indicate a significant and positive influence between the above-average level of education of Muslim households and the amount of charitable expenditure of the household. A household headed by a person with a high school, vocational school, or university education is predisposed to a higher amount of alms giving. Individual characteristics of the household head, including marital status, occupation, and religious observance, play a significant role in determining the amount of household alms given. This research has potential implications for providing recommendations to the community, religious institutions, and the government to increase participation and the amount of alms given.

The Intimacy with Muzakki in Increasing Trust, Commitment and Loyalty to Increase ZISWAF Fund at Zakah Institutions
Authors: Soleh Mochammad , Linggasari Yasinta Suci
Published: December 2023

Abstract
This study aims to determine the effect of the intimacy of zakat institutions with muzakki in order to gain trust, commitment and loyalty in order to encourage an increase in charitable funds, namely Zakat, Infaq and Sadaqah (ZIS). This study uses a quantitative approach through the Partial Least Square (PLS) method on 132 muzakki permanent members of zakat institutions using the variables of familiarity, trust, commitment, and loyalty. The results of this study note that the closeness of the relational relationship between zakat institution officials and muzakki as assessed from the familiarity factor in general has a positive relationship with the emergence of trust and commitment which in turn fosters muzakki's loyalty to the zakat institution they choose; However, this closeness does not significantly influence the emergence of trust, commitment and loyalty. One of the reasons for this to happen is that the public still has high distrust of zakat institutions, so it is very important for zakat institutions to start using a professional and responsible management pattern and have the support of all people.

Penelitian ini bertujuan untuk mengetahui pengaruh keakraban lembaga zakat dengan muzakki guna mendapatkan kepercayaan, komitmen dan loyalitas agar mendorong peningkatan dana amal yaitu Zakat, Infaq dan Shadaqah (ZIS). Penelitian ini menggunakan pendekatan kuantitatif melalui metode Partial Least Square (PLS) pada 132 muzakki anggota tetap lembaga zakat dengan menggunakan variable keakraban , kepercayaan, komitmen, dan loyalitas. Hasil penelitian ini diketahui bahwa keeratan hubungan relasional antara petugas lembaga zakat dan muzakki yang dinilai dari faktor keakraban secara umum memiliki hubungan yang positif dengan timbulnya kepercayaan dan komitmen yang pada akhirnya menumbuhkan loyalitas muzakki pada lembaga zakat yang mereka pilih; akan tetapi keeratan tersebut tidak berpengaruh secara signifikan terhadap munculnya kepercayaan, komitmen dan loyalitas. Salah satu sebab hal tersebut terjadi adalah masih tingginya ketidakpercayaan masyarakat terhadap lembaga zakat sehingga sangat penting bagi lembaga zakat untuk mulai menggunakan pola manajemen yang profesional dan bertanggung jawab serta mendapat dukungan dari semua umat.

Authors: Danniswara Fadia Ghaisani , Agustini Lukisiari
Published: December 2023

Introduction: Compressive optic neuropathy (CON) is the impairment of optic nerve function by space-occupying lesions that mechanically compress the optic nerve or optic tract. CON can arise from either intrinsic or extrinsic compression, and determining the underlying cause is important to approach the correct management. The objective of this case report is to present a rare case of CON secondary to an inflammatory polyp that mimicking lymphoma. Case Presentation: A 68-year-old male patient came to the neuro-ophthalmology clinic with a chief complaint of blurry vision in his left eye since three months ago that was getting worse until he lost his vision accompanied by drooping of the upper left eyelid. He also felt pain in his left eye, nausea, vomiting, and headache. Visual acuity of the right eye was 5/5 and the left eye had no light perception. Ocular motility of the left eye was restricted in all gaze. The pupil was 6 mm with no light reflex, and edema in the optic nerve head in the left eye was found from the posterior segment. The patient's MRI showed soft tissue thickening on the left orbital apex – left optic canal – left anterior cavernous sinus and enlargement of left medial rectus muscle with encasement of the left optic nerve, and from post-contrast showed contrast enhancement that suggested a lymphoma. He was diagnosed with CON secondary to lymphoma and was given Methylprednisolone 32 mg three times a day orally. Conclusions: Several differential diagnoses resemble the findings of CON secondary to inflammatory polyp. Some diagnostic examination must be done to exclude the other diagnosis to give a proper treatment for the patient.

The issue of trade liquidity analysis is continuously current, significant and complex. Starting from that, this paper analyzes the liquidity of Serbian trade for the period 2013 - 2021 based on ratio analysis, regression analysis and the MARCOS method. The aim and purpose of this is to identify key factors in the function of improving the liquidity of Serbian trade by controlling them more effectively. In this particular case, the coefficient of determination is high at the level of statistical significance ( Adjusted R Square .995; Sig. F Change .004). According to the regression analysis, the influence of certain factors on trade liquidity in Serbia is different. Important factors in this particular case include the size of the company and efficiency. Their effective control can influence the achievement of the target liquidity of trade in Serbia. According to the results of the MARCOS method, the best liquidity of trade in Serbia was in 2021. The following are: 2019, 2018, 2020, 2017, 2016, 2013, 2015 and 2014. Effective management of working capital and sources of their financing can, among other things, influence the achievement of the target liquidity of trade in Serbia.

DESENVOLVIMENTO MOTOR E COGNITIVO NOS ANOS INICIAIS: UM ESTUDO TRANSVERSAL
Authors: ALBERT ÉVELIN
Published: December 2023

Este artigo é fruto de uma pesquisa feita com crianças entre 9 e 11 anos de uma escola pública do município de Porto Alegre, Rio Grande do Sul,  e teve por objetivo  investigar o desenvolvimento motor e escolar delas. Sabendo-se que dos 9 aos 11 anos a criança já deveria ter atingido o estágio maduro e especializado  do movimento, os resultados desta pesquisa apresentaram que elas encontravam-se em estágios abaixo do esperado para a sua faixa etária. O mesmo ocorreu quando elas foram testadas quanto ao seu desempenho escolar.  Em crianças  que possuíam Transtorno do Déficit de Atenção com Hiperatividade (TDAH​), os índices de desenvolvimento motor mostraram-se ainda menores. Desta forma, pode-se concluir que possivelmente pela falta de oportunidades para a prática, encorajamento e instrução em um ambiente que promova o aprendizado dos movimentos, as crianças pesquisadas encontram-se nos estágios motores e escolares apresentados.

Introdução: A qualidade alimentar e a saúde mental afetam diretamente o desempenho esportivo. No entanto, a relação dos aspectos psicológicos e da qualidade da dieta com o desempenho físico de jogadores de futebol ainda é pouco estudada. Este estudo tem como objetivo identificar a qualidade dos hábitos alimentares de jogadores profissionais de futebol e sua relação com a saúde mental e o desempenho físico. Métodos: Participaram 27 atletas profissionais de futebol do sexo masculino. A saúde mental foi avaliada por meio do Self-Reporting Questionnaire (SRQ-20) e da Escala de Ansiedade e Depressão (DASS), a qualidade dos hábitos alimentares foi avaliada por meio de testes incluídos nas diretrizes alimentares nacionais, e os dados de desempenho físico foram coletados por sistema GPS específico para futebol. Resultados: A saúde mental foi correlacionada com a qualidade dos hábitos alimentares, mas esses parâmetros não se correlacionaram com os parâmetros de desempenho físico. Os escores dos questionários de saúde mental foram significativamente diferentes quando os atletas foram divididos em dois grupos, de acordo com a qualidade de seus hábitos alimentares. Os atletas consumiam poucas frutas, cereais, vegetais e verduras, enquanto consumiam grandes quantidades de carne e ovos. Conclusões: Uma vez que os hábitos alimentares dos jogadores estão contra as recomendações exigidas pelo esporte, esses achados reforçam a importância de uma abordagem multidisciplinar, considerando a complexidade dos determinantes do desempenho no futebol.

The genus Euonymus (L.) consists of shrubs or woody plants, distributed mainly in the Northern Hemisphere. To date, from Euonymus spp. several hundreds of different secondary metabolites have been isolated and identified. In addition, fatty oil was found in the fruits of some species of these plants, which accumulates not only in the seeds, but also in the arils. This study presents the research of unique long-term (ten-year-old) suspension cell cultures of Euonymus maximoviczianus Prokh. which were obtained from arils of unripe capsules. Suspension cells retain the ability to form oil droplets containing neutral lipids, both in the dark and in the light, the cells are able to synthesize very-long-chain fatty acids (VLCFAs), and can synthesize delphinidin-3-O-hexoside, cyanidin-3-O-hexoside, and peonidin-3-O-hexoside. Here, we research of the fatty acid, VLCFA, and anthocyanin biosynthesis dynamics in the subcultivation, as well as the influence of methyl jasmonate (MeJa) on these processes in the dark- and under-light-grown cell cultures. In the darkness, the formation of VLCFAs is more intense, and the biosynthesis of anthocyanins is significantly activated in the light. MeJA substantially enhances the biosynthesis of anthocyanins in the light and, surprisingly, the formation of VLCFAs in the darknss. In connection with the commonality of the cytosolic pool of malonyl-CoA, which is necessary both for the biosynthesis of VLCFAs and dihydroflavonols (and, ultimately, anthocyanins), the competition of these biosynthetic pathways is discussed.

Babesia microti (B. microti), is a tick-transmitted protozoan parasite that infects red blood cells. It is the primary cause of human babesiosis in the US. It is also considered an emerging pathogen that continues to expand in terms of both numbers of cases and geograpical range. The severity of babesiosis can range from asymptomatic to fatal. Nevertheless, the mechanisms important for resolution of infection versus pathology remain largely unknown. In the current study we used a mouse model to evaluate factors important in protection from reinfection with B. microti following the clearance of a primary infection. Both B cell and CD4 T cell deficient mice failed to completely eliminate parasitemia 36 days post-infection following primary challenge. In the recall mouse model of infection, wild type or specific gene deleted mice were reinfected with the same strain of B. microti parasites 30-36 days after the initital primary infection, and the development of parasitemia was evaluated. Our results show that wild type mice were protected from reinfection with B. microti. In contrast, B cell and CD4 T cell deficient mice were only modestly impaired in their ability to protect against rechallenge as protection was more similar to reinfected wild type mice than naïve mice. However, one reinfected B cell deficient mice developed parasitemia levels similar to those observed in primary infection. Other factors including IFN-γ, inducible nitric oxide synthase (iNOS) and the adaptor protein MyD88 important for signling via IL-18 and IL-1 had no effect on rechallenge. Thus our study shows that infection with B. microti confers at least short term protection against rechallenge with the same parasite strain. Our data show that CD4 T cells make an important contribution to both primary and rechallenge infection with B. microti. They also suggest that antibody might play an important role in protection against reinfection or persistent infection. However, overall our results Our results suggest that no one aspect of the immune system is solely responsible for adequate protection against reinfection with B. microti.

In recent years, Edge Intelligence (EI) has emerged, combining edge computing with AI, specifically deep learning, to run AI algorithms directly on edge devices. In practical applications, EI faces challenges related to computational power, power consumption, size, and cost, with the primary challenge being the trade-off between computational power and power consumption. This has rendered traditional computing platforms unsustainable, making heterogeneous parallel computing platforms a crucial pathway for implementing EI. In our research, we leveraged the Xilinx Zynq 7000 heterogeneous computing platform, employed High-Level Synthesis (HLS) for design, and implemented two different accelerators for LeNet-5 using loop unrolling and pipelining optimization techniques. The experimental results show that when running at a clock speed of 100 MHz, the PIPELINE accelerator, compared to the UNROLL accelerator, experiences an 8.09% increase in power consumption but speeds up by 14.972 times, making the PIPELINE accelerator superior in performance. Compared to the CPU, the PIPELINE accelerator reduces power consumption by 91.37% and speeds up by 70.387 times, while compared to the GPU, it reduces power consumption by 93.35%.This study provides two different optimization schemes for edge intelligence applications through design and experimentation, and demonstrates the impact of different quantization methods on FPGA resource consumption. These experimental results can provide a reference for practical applications, thereby providing a reference hardware acceleration scheme for edge intelligence applications.
