Gambaran Efektivitas Transfusi Thrombocyte Concentrate Pada Pasien Immune Thrombocytopenic Purpura di RSUP Dr. M. Djamil Padang
Authors: Santril Nitri Ramadhani
Published: August 2024

Latar Belakang: Transfusi trombosit pasien immune thrombocytopenic purpura (ITP) diindikasikan pada kasus ITP dengan perdarahan. Transfusi trombosit pada pasien ITP tidak diikuti dengan peningkatan jumlah trombosit. Corrected count increment (CCI) merupakan penghitungan untuk menilai efektivitas transfusi trombosit. Efektif bila CCI 1 jam pasca transfusi >7,5 x 109/L dan CCI 24 jam >4,5 x 109/L. Tujuan: Mendapatkan gambaran efektivitas transfusi trombosit concentrate (TC) berdasarkan nilai CCI. Metode: Penelitian dilakukan terhadap 31 pasien ITP yang mendapatkan transfusi TC Desember 2022- April 2023. Efektivitas transfusi dinilai berdasarkan nilai CCI 1 jam dan 24 jam pasca transfusi. Hasil: Median jumlah trombosit sebelum transfusi adalah 5,0 x 103/L. Median CCI (Min-Maks) 1 jam 1,88 (0,26-14,5) dan medianCCI 24 jam adalah 2,39 (0,26-15,89). Sebanyak 16,1% sampel efektif berdasarkan nilai CCI 1 jam dan 83,9% tidak efektif. Nilai CCI 24 jam pasca transfusi, 35,5% efektif dan 64,5% tidak efektif. Diskusi: Transfusi TC pada pasien ITP tidak efektif berdasarkan nilai CCI 1 jam dan 24 jam karena pendeknya masa hidup trombosit yang ditransfusikan akibat didestruksi oleh sistem imun. Simpulan: Efektivitas transfusi TC pasien ITP berdasarkan nilai CCI 1 jam pasca transfusi adalah 16,1% pasien dan CCI 24 jam adalah 35,5%. Transfusi trombosit pada ITP perlu indikasi tepat

Examining learning from failure to venture growth: Empirical study in hospitality SMEs in Indonesia
Authors: Prihandono Dorojatun , Abiprayu Kris Brantas , Wijaya Angga Pandu , Ismail Norain
Published: August 2024

This study investigates the crucial role of learning from failure in shaping venture growth within the context of the hospitality industry, particularly in light of recent challenges posed by increasingly complex and competitive external factors. The hospitality industry has been the most severely affected by the crisis, making it a relevant context for research. Employing a quantitative approach, the study examines the influence of emotions, narcissism, and stock of knowledge on learning from failure and its subsequent impact on venture growth. A total of 161 respondents, all owners of SMEs in the hospitality sector, completed the questionnaire. The data obtained were analyzed using variance-based structural equation modeling (VB-SEM). The results indicate that while emotions and narcissism present obstacles and opportunities for learning, a strong stock of knowledge positively affects learning from failure and venture growth. However, the study shows that narcissism does not directly influence venture growth but does so indirectly through learning from failure. These findings underscore the importance of fostering a culture that embraces failure as a catalyst for innovation and resilience in adversity. The study contributes valuable insights into the dynamics of learning from failure and its implications for entrepreneurial success in the hospitality industry.

Authors: Mulyani Susi Dwi , Levana Dhia Prawati  , Amalia Puspita Wardhani  , Hamzah Noradiva
Published: August 2024

This study analyzes the influence of taxpayer knowledge and procedural justice on tax compliance. This study also analyzes the role of power legitimacy as a mediating variable. Legitimacy of power is expected to mediate the influence of taxpayer knowledge and procedural justice in increasing taxpayer compliance. This research is quantitative research that tests hypotheses using primary data through distributing questionnaires.
The population in this research is individual taxpayers who carry out business activities and tax consultants who are members of the Indonesian Tax Consultants Association (IKPI). The sampling technique uses convenience sampling. Hypothesis testing uses SEM PLS statistical tools by conducting path analysis tests to obtain results of the direct influence of taxpayer knowledge and procedural justice on tax compliance and the indirect influence, namely taxpayer knowledge and procedural justice on tax compliance through the mediating variable power legitimacy.
These results of hypothesis testing prove that taxpayer knowledge and procedural justice each have a positive effect on power legitimacy and tax compliance. Besides that, power legitimacy also plays a role in mediating the influence of knowledge and procedural justice on tax compliance. This research can prove the theory of planned behavior that the behavior shown by a person arises because of the individual's inner intention to behave. The research implication from the theoretical aspect is that it can prove the role of power legitimacy as a mediating variable that links the influence of knowledge and procedural justice on tax compliance.

Effect of probiotic administration in adult atopic dermatitis patients
Authors: Paramita Dewita Nina Paramita , Sutanto Krisadelfa
Published: August 2024

Introduction: Atopic dermatitis (AD) is a chronic skin disease characterized by abnormal skin barrier function and heightened immunologic sensitization. Its incidence has surged recently, with approximately 60% of cases diagnosed within the first year of life. AD can persist or recur, significantly deteriorating the quality of life due to persistent itching and sleep disturbances. Individuals with AD are at increased risk of developing other atopic disorders like asthma and allergic rhinitis. Various dietary approaches, including low carbohydrate, calorie, and fat diets, have been associated with enhanced quality of life by regulating immune responses. Probiotics have been used as adjuvant therapy in allergic conditions, though their effectiveness varies due to the complex nature of allergies.
Method: A literature search was conducted using PubMed, Cochrane Library, and Google Scholar. MeSH terms, advanced search strategies, and predefined eligibility criteria were employed to identify relevant studies. Duplicate studies were excluded, and critical assessment tools and levels of evidence were defined per Oxford Center for Evidence-based Medicine standards.
Results: One systematic review and meta-analysis of randomized controlled trials (RCTs) met the PICO and eligibility criteria. The meta-analysis demonstrated that probiotics significantly decreased AD severity in adults, enhancing their overall quality of life. Other meta-analyses and systematic reviews supported that probiotics reduce clinical severity and improve life quality in adult AD patients.
Conclusion: Probiotic supplementation is a viable option to improve the quality of life for adult AD patients, offering potential therapeutic benefits in managing this condition.

A pragmatic comprehension of scientific and classical aspects of Rachana Sharir—A systematic review
Authors: Sabharwal Pooja , Jidani Srishti
Published: August 2024

Ayurveda, a flourishing traditional medical system renowned for its extensive knowledge, includes Rachana Sharir as a fundamental subject. Rachana Sharir Vigyan explores the anatomical aspects (Rachna) of the human body. The immense knowledge of the ancient wisdom of Ayurveda is not comprehensively described yet. The Samhitas and Vedas of Indian literature by different acharyas elaborate on how the human body evolved from a combination of Panchamahabhutas and Atma (Chetana). This review aims to elucidate the classical aspects of Rachana Sharir from Ayurvedic texts and establish correlations with contemporary scientific knowledge. Classical texts such as the Samhitas authored by various acharyas were systematically reviewed to gather insights into the origin, anatomical positions, numerical compositions, and classifications of human body parts, organs, tissues, and systems. The review reveals detailed principles and concepts from Ayurvedic literature, emphasizing contributions from Acharya Sushruta in the Sharir Sthana, particularly his meticulous descriptions of cadaveric studies and preservation techniques. Classical books explained the origins of human bodily parts, their anatomical placements, organs, tissues, systems, and more. These fall under human anatomy (Rachana Sharir), and this article explains its classical aspect with scientific and modern science linkages. In Sharir Sthana, one of Ayurveda’s main principles, cadaveric research and preservation, is beautifully illustrated by Acharya Sushruta. Ayurveda has scientific principles, logic, and subtle knowledge that we must explore to apply its gifts to humanity. This essay shows that Samhitas contains pragmatic and scientific knowledge. Ayurveda combines science and philosophy. Ayurvedic knowledge’s pragmatic and scientific usefulness beyond textual content must be explored and validated to maximize its benefits for humanity.

Objectives:

To evaluate the cosmetic result of nasal of an elliptical excision and primary closure on small nasal defect by using Scar assessment using the Stony Brook Scar Evaluation Scale (SBSES) score.

Material and Methods:

This retrospective interventional study was conducted in a private clinic over a 2-year duration. Patients aged 18–60 years with nasal defects <1.5 cm were enrolled after obtaining informed consent. Exclusion criteria included immunocompromised status, keloidal tendency, local site infection, bleeding disorder, age <18 years, and lack of consent. Scar assessment using the SBSES was performed at the end of 6 months. Statistical analysis included summary statistics, analysis of variance tests, and a significance level of P < 0.05.

Results:

The study included 50 patients, with 54% males and 46% females. The most common age group was 21–40 years, and melanocytic nevi was the most common cause for excision. Lesions were excised mainly from the lateral wall and dorsum of the nose. The mean SBSES score was 3.79 ± 0.467. The best cosmetic outcome was observed in lesions involving the dorsum followed by the root of the nose. No significant difference was found among the SBSES scores for various subunits.

Conclusion:

Elliptical excision with primary closure is a simple and effective technique for small nasal defects, providing good cosmetic results. The location of the nasal defect influences the cosmetic outcome, with better results observed in areas with thinner skin and increased skin laxity.

Authors: Alkeraye Salim , Alosaimi Khalid , Alrabiah Hamad F. , Alkahtani Rema , Alshehri Naif Ahmed , Alharbi Bander Ahmed
Published: August 2024

Objectives:

Acne scarring occurs from skin damage following acne healing. Treatments such as chemical peels, dermabrasion, and laser therapy can effectively enhance scars’ appearance but could be expensive. This study aimed to reflect participants’ awareness of treatment options and their willingness to pay (WTP), evaluating their association with sociodemographics, severity, and quality of life (QoL).

Material and Methods:

A cross-sectional study was conducted in Riyadh, Saudi Arabia, from June to July of 2023. Study participants were chosen using a non-probability sampling technique. Participants were aged 18 or older, had acne scarring, and resided in Riyadh. Data analysis was performed using RStudio, with P < 0.05 indicating statistical significance.

Results:

A total of 401 adult participants were included in the study. The prevalence of acne scarring among the participants was 63.4%. About 45.8% of the participants expressed a WTP of <1000 Saudi Riyals (SAR), while 42.2% were willing to pay 1000–6000 SAR. The most well-recognized acne scar management modalities were laser resurfacing (66.3%) and chemical peels (64.1%), while the least recognized were collagen/fat filler injections (23.9%) and radiofrequency microneedling (27.7%).

Conclusion:

The most recognized acne scar treatment modalities were laser resurfacing and chemical peels. Participants were willing to pay for reasons such as psychological impact, income levels, and awareness of treatment modalities. The findings could influence dermatologists to start awareness campaigns to debunk misconceptions about acne scar treatment modalities and their efficacy in improving QoL.
Study to compare the efficacy of 50% glycolic acid with 65% trichloroacetic acid in the treatment of atrophic acne scar by CROSS technique
Authors: Roy Gourab , Gayen Tirthankar , Sen Sumit , Rudra Olympia
Published: August 2024

Objectives:

Acne scars often become challenging to treat with satisfactory results. The chemical reconstruction of skin scars (CROSS) technique has been used with high concentrations of trichloroacetic acid (TCA) which often produces unacceptable side effects. There is a dearth of data, with 50% glycolic acid (GA) for the same indication in the management of acne scars in the Indian population. This study aimed to assess the clinical response of acne scars after the application of 50% GA with that after the use of 65% TCA in a similar manner.

Material and Methods:

An institution-based prospective comparative study was performed with patients aged 16–45 years of either sex with acne scars and not been treated within the past 1 year. Subjects were assigned to receive one of the formulations (50% GA [Group A] and 65% TCA [Group B]). Grading of scars was done on day 1 and day 35 based on patients’ assessment on a four-point visual scale and physicians’ assessment by the Goodman–Baron qualitative global acne scar grading scale. The procedure was repeated every fortnightly for three such. Data were analyzed by Statistica version 6 (Tulsa, Oklahoma: StatSoft Inc. 2001).

Results:

The visual improvement scale of patients showed 41.38% (n = 12) fair improvement in group A, whereas 58.06% (n = 18) showed good improvement in group B. Grading by the Goodman–Baron scale showed 9.68% (n = 3) showed four grade changes in group B.

Conclusion:

Improvement is best observed with 65% TCA. Adverse effects were noted more with 65% TCA, especially acneiform eruption which was lacking in the previous studies. GA can be a safer alternative to TCA with acceptable results. Our study opens the scientific window for future research on different concentrations of GA as a CROSS agent.

Человекоцентричный подход к управлению гибкими производствами В условиях цифровизации минимизируется влияние негативного человеческого фактора в производственной системе, человек получает возможность заниматься творческой деятельностью, а не рутинной, и трудиться в более комфортных условиях, то есть параллельно с техноцентричностью на производствах формируется человекоцентричность. В ИПУ РАН разработана методология моделирования процесса технологической подготовки гибкого производства всевозможных изделий (включая автоматы) в различных производственных условиях с учетом вероятностей качественного выполнения технологических операций. Отмечено, что гибкое производство может быть реализовано только в условиях цифровизации. Предложенные методы и алгоритмы способны гибко настраиваться на различные производственные условия и помогать технологу в принятии решения о возможности и целесообразности постановки изделия на производство. В качестве дальнейшего развития данной методологии обосновывается актуальность научной проблемы создания единого формализованного подхода для исследования процесса организации труда человека на гибких производствах. Показано, что компонентами формализованного описания являются вероятность качественного и своевременного выполнения технологической операции, а также вероятность сохранять требуемые рабочие качества на протяжении профессиональной карьеры. Определять указанные вероятности предлагается с использованием результатов обучения и тестирования работников на компьютерных тренажерах, а также мониторинговых опросов производственного персонала.

We developed a novel approach to isolate and recollect or remove nearly any compound from complex GCxGC chromatograms. This was achieved by modifying a thermal desorption-GCxGC-Q-TOF system with a Deans switch, a passive splitter, and careful optimization of flows and capillary dimensions. The setup was evaluated with 106 standard chemicals covering a wide range of volatility (boiling points: 56 – 343 ⁰C) and polarity (log P: -0.2 – 9.4). We found that the recovery from tube to tube can become highly efficient if a custom-made adapter is attached directly on the flame ionization detector port (average recovery rate of 76 ± 7%). Furthermore, we were able to isolate peaks separated by a minimum distance of 50 milliseconds from each other at the base throughout the whole chromatographic run. In addition, the setup was designed for easy adaptation by repurposing existing instrument control software to define the isolation windows for the compounds of interest (first and second column retention time windows). We expect this novel development to allow several new applications, e.g., the isolation and selective enrichment or removal of molecules in food and flavour analysis; the investigation of suspect chemicals (incl. unknowns) for effect directed analysis (e.g., bioassays), and the isolation of compounds in the high-ng range (upon multiple isolation iterations) to be subjected to further chemical analyses (e.g. chemical ionization tandem mass spectrometry).

Organometallic oxidative addition complexes (OACs) have recently emerged as a powerful class of reagents for the rapid and chemoselective modification of biomolecules. Notably, the steric and electronic properties of the ligand and aryl group can be modified to tune the kinetic profile of the reaction and permit regioselective S-arylation. Using the recently developed dicyclohexylphosphine-based bidentate P,N-ligated Au(III) OACs, we computationally and experimentally examined the effects of sterically bulky and electron deficient aryl substrates to achieve selective S-arylation. With this mechanistic insight, aryl substrates based on 4-iodoanisole and 3,5-dimethyl-4-iodoanisole were incorporated as end groups to generate a heterotelechelic bis-Au(III) poly(ethylene glycol) (PEG). This reagent performed rapid and regioselective S-arylation with a model biomolecule, designed ankyrin repeat protein (DARPin), to form a protein-polymer OAC in situ. This OAC mediated a second S-arylation with biologically relevant thiolated small molecules (metal chelator, saccharide, and fluorophore) and macromolecules (polymer and therapeutic peptide). It is envisioned that this approach could be utilized for the rapid construction of biomacromolecular heteroconjugates with S-aryl linkages.

The abatement of aromatic pollutants in water requires resource-intensive oxidation to nontoxic products by hydroxyl radicals (•OH). In this study, we elucidate the mechanisms of •OH-induced aromatic ring degradation by combining kinetic measurements, electron paramagnetic resonance spectroscopy, density functional theory (DFT) calculations, and kinetic modelling. We demonstrate that benzyl alcohol, a model aromatic compound, is oxidized by •OH radicals, generated by ultrasonic irradiation in an O2-rich environment, into aromatic compounds (benzaldehyde and phenol derivatives) and C1-C2 oxygenates (formic acid, glyoxal, and oxalic acid). Through pathways akin to atmospheric chemistry, these •OH radicals de-aromatize and fragment benzyl alcohol, producing 5-hydroxy-4-oxo-pentenal and other dicarbonyl products. Unique to the aqueous phase, however, superoxide (•O2–) is generated as a byproduct of •OH-benzyl alcohol reactions. •O2– acts as a potent nucleophile, oxidizing 5-hydroxy-4-oxo-pentenal into oxalic acid and C1 oxygenates via aldehyde and ketone intermediates. This process regenerates •O2– and does not consume •OH, thereby further degrading ring fragmentation products while preserving •OH to activate the refractory aromatic ring of benzyl alcohol. These nucleophilic •O2– reactions can therefore reduce the energy and chemical demands needed to degrade aromatic compounds, thus promoting the sustainable and scalable application of •OH-based oxidation processes in water treatment.
Flavylium merocyanine dyes: Exploiting the cyanine state for intrinsic labeling of the endoplasmic reticulum

Merocyanine dyes are a versatile class of donor-acceptor polymethine dyes that exhibit unique properties depending on their structural makeup and surrounding environment. Scaffolds that favor the cyanine state (i.e., narrow, red-shifted absorption and high fluorescence quantum yields) in biologically relevant settings are highly advantageous for multiplexed labeling experiments, but remain limited by their visible absorption. Herein, we report a new class of far-red (650-700 nm) flavylium merocyanine dyes that favor the cyanine state with increasing solvent viscosity and hydrogen bond donation, enhancing their performance in biological settings. We leveraged these properties for live cell labeling, where we observed intrinsic targeting to the endoplasmic reticulum (ER) and lipid droplets, and minimal crosstalk with commercial stains. As such, these dyes are a promising alternative to commercially available ER stains at shorter absorption wavelengths (<600 nm) with complex targeting moieties.
Modeling the ionization efficiency of small molecules in positive electrospray ionization

Technological advancements in liquid chromatography (LC) electrospray ionization (ESI) high resolution mass spectrometry (HRMS) have made it an increasingly popular analytical technique in non-targeted analysis (NTA) of environmental and biological samples. One critical limitation of current methods in NTA is the lack of available analytical standards for many of the compounds detected in biological and environmental samples. Computational approaches can provide estimates of concentrations by modeling the ionization efficiency of a compound expressed as the relative response factor (RRF). In this paper, we explore the application of molecular dynamics (MD) in the development of a predictive model for RRF. We obtained measurements of RRF for 48 compounds with LC - quadrupole time-of-flight (QTOF) MS and calculated their RRF by dividing the observed peak areas by their concentrations. We used the CGenFF force field to generate the topologies and GROMACS to conduct the (MD) simulations (t = 1 ns). We calculated the Lennard-Jones and Coulomb interactions between the analytes and all other molecules in the ESI droplet, which were then used to construct a multilinear regression model for predicting RRF. The best performing model showed a coefficient of determination (R2) of 0.82 and a mean absolute error (MAE) of 0.13 log units. This performance is comparable to other predictive models including machine learning models. While there is a need for further evaluation of diverse chemical structures, our approach showed great promise in predictions of RRF.

Published: August 2024

Addressing the growing concern of antibiotic-resistant bacteria, we developed a series of novel polymeric nanoantibiotics with a dual-war- head system that induces physical lysis upon copolymer coalescence with bacterial matter. These polymers are equipped with two orthogonal binding motifs that form electrostatic interactions and dynamic covalent complexes on bacterial surfaces and exhibit potent antibacterial activity against gram-positive and gram-negative bacteria. The effect of the chemical composition and architecture of copolymers incorporating phenylboronic acid and quarternary ammo- nium groups on the antimicrobial activities was systematically examined. This work expands the current chemical repertoire to combat antimicrobial re- sistance by polymeric nanoantibiotics with a unique mode of action.
