Export diversification and economic growth in Bangladesh
Authors: Azam Musharrat , Azam Samiha
Published: February 2023

Although the growth in exports of Bangladesh over the past few decades has been exemplary, it is enormously concentrated on just one industry which is the Ready Made Garment (RMG) sector. This over dependence on just one sector for export earnings places Bangladesh in a vulnerable position. This study examined the relationship between export diversification and growth rate of the Gross Domestic Product (GDP) of Bangladesh using annual data from 1995 to 2020. The study utilized the Autoregressive Distributed Lag (ARDL) bounds test to cointegration approach to estimate the long run relationship and the error correction model to determine the existence of a short run relationship. The results from the study indicate that there exists a significant long run cointegrating relationship between overall export diversification and economic growth in Bangladesh. In the long term, if horizontal export diversification increases by 1%, the GDP growth rate shall rise by around 1.7%. Conversely, the short run relationship between export diversification and economic growth is proven to be insignificant. The results of this study implore that Bangladesh should implement strategies and policies that will diversify its exports and shift away from the dominance of just one exporting sector.

Authors: Mulyana Yaya , Jamaludin Maun
Published: February 2023

In the effort to achieve good and effective public services to gain public satisfaction and trust, the use of public electronic services (e-services) is expected to improve service quality. Public e-services offer better options for processing digital data. With increasing internet access, the use of e-services as a vehicle for delivering various public services is a promising development in the public sector. By maintaining and improving service quality, especially in the public sector, the use of internet/online services or public e-services will make users feel more satisfied and increase public trust. This study aims to determine the effect of electronic service quality on citizen satisfaction with public e-services. A quantitative research methodology was adopted. Data was collected by distributing online questionnaires to users of public e-service applications, totaling 150 respondents in Bandung, Indonesia. The sampling technique used was a purposive, non-probability-based sampling method. The data analysis technique was Structural Equation Modeling (SEM) using Smart software. The test results show that information quality, data security, and data privacy have a significant effect on e-service quality, which, in turn, has implications for citizen satisfaction. Based on the results of this study, we advise public e-services institutions to maintain and improve the quality of e-services by improving information quality, data security, and data privacy to increase user trust in public e-services.

Background: The sterility mosaic disease in pigeon pea caused by pigeon pea sterility mosaic virus is a serious threat to pigeon pea cultivation in India. A little information is available on the biochemical changes in pigeon pea plant against the SMD disease. Hence present study was taken to know the biochemical alterations in different pigeon pea genotypes due to sterility mosaic disease. Methods: Studies were conducted on the composition of the chlorophyll pigment, total soluble protein (%), total sugars, phenol, tannins, peroxidase and phenol peroxidase in six different genotypes. Result: The results of the study showed that there was a reduction in chlorophyll pigment composition, total soluble protein (%) and total sugars in all infected genotypes, but the reduction in resistant genotypes was less compared to other genotypes. In resistant genotypes, the amounts of phenols, tannins, peroxidase and phenol peroxidase were increased, where as in susceptible genotypes, they were roughly equal to the amounts in uninoculated genotypes. The increase in phenols, tannins, peroxidase and phenol peroxidase in resistant genotypes can be correlated with disease resistance.

Branding is urgent in a business because it is through branding that consumers know our commodities. However, business actors often do not pay much attention to branding and marketing their products. This is the reason for holding this mentoring program. Panti Asuhan Muhammadiyah Pamekasan already has produced results in the form of flip-flops but only for the internal needs of the orphanage and has not been able to market it to outside parties because it does not have branding. This empowerment method uses Asset-Based Community-driven Development (ABCD) with a target of 25 children from Panti Asuhan Muhammadiyah Pamekasan. From this mentoring program Panti, Asuhan Muhammadiyah Pamekasan has been able to make flip-flops branding by doing screen printing on the sandals produced so that they can market their products to shops around the orphanage, the results of which are used to support the independence of the orphanage.(Branding menjadi hal yang sangat urgen dalam sebuah usaha karena melalui brandinglah komoditas kita dikenal oleh konsumen.

Published: February 2023

Dengue patients may experience some grade of severity. Cardiac involvement is common in severe dengue, therefore cardiac markers could be used to ensure the diagnosis of dengue myocarditis. However, information of the cardiac marker profiles in patients with milder severity of dengue infection is limited. The study aimed to evaluate creatinine kinase (CK), creatinine kinase-MB (CK-MB) and troponin I (TnI) in dengue myocarditis against the spectrum severity of dengue infection in children. This cross-sectional study was conducted using secondary data from medical records of dengue myocarditis patients aged 1-18 yr in Dr. Sardjito General Hospital, Yogyakarta. Fisher’s Exact tests were performed to compare the increase in cardiac markers to the dengue severity. The increase of CK was observed in dengue fever/DF (6 or 75% of patients), dengue hemorrhagic fever/DHF (6 or 67%) and dengue shock syndrome/DSS (16 or 73%). Furthermore, the increase of CK-MB was also observed in DF (6 or 75%), DHF (8 or 87%), and DSS (21 or 95%). No significant difference in the increase of CK and CK-MB proportions was observed in DF compared to DHF groups and in DF compared to DSS (p>0.05). The increase of Tn I was observed in DHF (2 or 22%) and DSS (10 or 45%) groups but not observed in DF group. Significant difference in the increase of Tn I proportion was observed in DF compared to DSS groups (p=0.022). In conclusion, cardiac involvement is common in all dengue severity level. The increment of Tn I corresponds to an increase in the dengue severity level. Further research by observing cardiac markers sequentially is needed.

The purpose of this paper was to unpack French-minority language teachers’ perspectives on the impact of the pandemic on their teaching. In fall 2021, semi-structured interviews were conducted virtually with 40 K-12 teachers of French as a minority language in Manitoba and Nova Scotia. While the pandemic has undoubtedly been challenging for language and literacy teachers, many have also developed adaptations and strategies. This paper focuses on those pedagogical accomplishments and teachers’ self-reported moments of success. Three main themes explored were the integration of technology into language teaching, language teacher collaboration and linguistic community building with students.
Learning to Teach Outside the Box: Exploring Newness in Literacies Pedagogies in a Pandemic
Authors: McKee Lori , Murray-Orr Anne , Throop-Robinson Evan
Published: February 2023

This article explores the innovative lesson planning assignments of preservice teacher, Marie, as part of an alternate teaching practicum during the pandemic closure of schools in Spring 2020. Marie viewed this shift in context as an opportunity to “think outside of the box”, to be creative and divert from a traditional lesson planning template. As we read the examples from Marie’s lesson plan assignments, we think with posthumanist theories of entanglement, intra-actions and the producing of newness in literacies pedagogies. We share data that show the entanglements of more-than-humans and humans within the innovative lesson plan format. In exploring Marie’s lesson plan redesigns and her reflections on them, we consider the ways these pedagogies were produced through the intra-actions of assignment criteria, provincial curricula, Marie’s knowledge of her students, families, available learning materials, and pandemic conditions. We consider how the implications of this lesson format contribute to newness in our ways of thinking and doing as teacher educators of literacies.

Aim: In long-term nucleos(t)ide analog (NA) suppressed patients with chronic hepatitis B (CHB), hepatocellular carcinoma (HCC) can still develop. Few data exist on the incidence and the predictors of HCC development beyond the first five years in long-term treated patients. To assess the prevalence, incidence, and risk factors for HCC development in a real-life cohort of successfully NA-treated CHB patients for more than five years. Methods: All CHB patients under NAs for ≥ 60 months with stable virologic response were enrolled. HCC surveillance was carried out using liver ultrasound and dosing of serum alpha-fetoprotein every year in patients with CHB and every six months in cirrhotic patients. The baseline PAGE-B score was calculated for each patient. Results: 343 patients (76% male, 86% HBeAg-negative, 30% cirrhotic) were enrolled. During a median (IQR) follow-up of 144 (105-182) months, 21 patients (6%) developed HCC despite virologic suppression (incidence rate 40 cases/1000 person-years follow-up). In multivariate analysis, higher PAGE B score [adjusted Hazard Ratio, aHR 1.26 (95%CI: 1.13-1.54), P = .022] and cirrhosis [aHR 9.71 (95%CI: 2.02-46.48), P = .005] were predictors of HCC development. PAGE B score showed a significant association with HCC (R2 0.225, P < .001) and good prognostic capacity (AUC 0.863) of HCC. Conclusions: Our results confirm that in successfully NA-treated CHB patients, sustained viral replication suppression does not abolish the risk of HCC. The PAGE-B score could be a useful tool for identifying high-risk subjects.

At present, cellular networks provide ubiquitous Internet connection, but with relatively expensive cost. Furthermore, the cellular networks have been proven to be insufficient for the surging amount of data from Internetenabled mobile devices. Due to the explosive growth of the subscriber number and the mobile data, cellular networks are suffering overload, and the users are experiencing service quality degradation. In this project implement seamless and efficient Wi-Fi based Internet access from moving vehicles. In our proposed implementation, a group of APs are employed to communicate with a client (called AP diversity), and the transmission succeeds if any AP in the group accomplishes the delivery with the client (called opportunistic transmission). Such AP diversity and opportunistic transmission are exploited to overcome the high packet loss rate, which is achieved by configuring all the APs with the same MAC and IP addresses. With such a configuration, a client gets a graceful illusion that only one (virtual) AP exists, and will always be associated with this virtual AP. Uplink communications, when the client transmits a packet to the virtual AP, actually multiple APs within its transmission range are able to receive it. The transmission is successful as long as at least one AP receives the packet correctly. Proposed implementation will show that outperforms existing schemes remarkably.

Adoption is a form of alloparenting in which an individual raises an unrelated offspring, although it is sometimes unclear whether this behaviour is adaptive or the product of reproductive error. Here, we report an observation of intraspecific adoption in a cooperatively breeding songbird, the Superb Fairy-wren Malurus cyaneus. In a colour-banded population at Cleland Conservation Park, South Australia, a breeding pair with three nutritionally dependent fledglings adopted an additional male fledgling from an adjacent territory. The adoptee was first observed with the new group about 2 weeks after fledging and was regularly fed by his adoptive parents. The fledgling continued to associate with his adoptive group for at least 7 months, even though his natal group remained intact in the adjacent territory. Genetic analyses confirmed that the adopted fledgling was the product of within-pair mating and was not closely related to its adoptive parents. There is some evidence that adult fairy-wrens may discriminate against offspring based on the acoustic structure of their begging calls; however, begging calls recorded at the adoptee’s nest were equally similar to incubation calls from both the genetic and adoptive mother. Finally, we discuss similar instances in the literature of intraspecific and interspecific adoption by Superb Fairy-wrens and suggest possible explanations for this behaviour.

In recent years, the production of renewable energy represents one of the main challenges of modern and future society. The new cultivation method called Agrivoltaic (hereafter AV), combines and associates agricultural production and renewable energy (photovoltaic) production in a collaborative synergy from which both benefit. In this study, the dry matter and essential oils yield of six medicinal species (Salvia officinalis L., Origanum vulgare L., Rosmarinus officinalis L., Lavendula angustifolia L., Thymus citriodorus L. and Mentha spicata L.) grown underneath a dynamic AV system in comparison to those in full sun (T), were evaluated. In particular, below the dynamic AV system, due to the rotation of the panels, two plot areas on the ground were distinguished: one always covered by the panels (UP), and another one covered alternatively (BP). During the aromatic crop cycles, the solar radiation, infrared leaf temperature and air temperatures in UP, BP and T plot, were measured. In addition, at harvest time, weed survey was carried out. The results showed that, in general, the solar radiation and infrared leaf temperature were lower in UP plot than in either the BP and T plots, while the air temperatures were similar in all compared plots. Also the weed cover percentage was lower in the UP plot than other ones. The essential oils yield in the sage, thyme, mint and rosemary plants were higher in both UP and BP plots than for T plot. Thus, shading and/or less weed infestation may have been the main factors favorably influencing the performance of medicinal crops under a dynamic AV system.
The Most Stable Structure of PTB7-Th: DFT Conformational Analysis
Authors: Ayoub Sarah , Lagowski Jolanta
Published: February 2023

PTB7-Th is an important donor copolymer used in construction of many organic devices and other industrial applications. In this work, we investigate the structure and energetics of PTB7-Th. We employ density functional theory (DFT) (B3LYP), dispersion corrected DFT (B3LYP-D3) and long-range corrected DFT (CAM-B3LYP, LC-BLYP, and ωB97xD) to analyze the conformational structures and their corresponding energies to determine the lowest energy state of PTB7-Th. The role of the alkane side chains is carefully investigated. Our findings indicate that, when branched ethylhexyl side chains are present, the lowest energy structure of PTB7-Th has fluorine in the same plane and the same side as the double bonded oxygen in the TT-CF part of the monomer and S-C-C-S dihedral angles along the chain backbone are cis-like having values in the range of 20-30 degrees in most cases. Without these side chains the polymer, not unexpectedly, has many near conformational degeneracies.

Основная цель будущих лунных проектов, безусловно - обеспечение успешной доставки максимально возможного количества полярного лунного реголита, взятого с разной глубины, с сохранением летучих веществ и водяного льда. Кроме этого, в дополнительные цели такого проекта включено создание космического комплекса на поверхности Луны на базе посадочных аппаратов, а также возврат на Землю биологических образцов и электронных компонентов, прошедших длительное экспонирование на поверхности Луны в составе предыдущих посадочных аппаратов. Для реализации этих целей необходимо обеспечить технологическую мобильность в окрестности посадки посадочного модуля. Это включает различные операции как в непосредственной окрестности места посадки для прямой помощи в сборе образцов грунта, так и в удалённой окрестности для доставки биологических образцов и электроники. Наиболее универсальным средством для решения этих задач является автономный луноход малого или среднего класса, оснащённый манипулятором для сбора и переноски различных образцов и научных модулей и имеющий возможность прямого телеуправления с Земли. В дополнение к основным целям миссии, наличие автономного лунохода, способного многократно пережить лунную ночь, также означает существенное расширение научной программы миссии, позволяя её продлить и после старта возвращаемого модуля с образцами лунного грунта, обеспечивает возвращение после долгого перерыва к практике использования луноходов и даёт возможность отработать элементы и основные принципы будущей лунной геологоразведки. Поэтому мобильность на поверхности Луны в реализации космического эксперимента, проводимого в рамках будущей посадочной миссии, является приоритетной задачей, а её возможные реализации должны быть детально изучены для выбора оптимальной концепции лунохода. С учётом изучения лётных образцов, прототипов и современных космических технологий можно будет реализовать концепцию лунохода малого или среднего класса и наделить его достаточно большой функциональностью для таких задач, как: съёмка окрестности места посадки, посадочного модуля и процесса бурения и забора грунта, сбор и доставка образцов с поверхности Луны, собранных в окрестности места посадки, перенос и установка на поверхность автономных исследовательских модулей в окрестности мета посадки ПМ (сейсмометры, термодатчики), и многие другие.

Published: February 2023

Failed brakes are an event or damage to a motorized vehicle component that can cause an accident as well as be a life threat to the driver. There are several factors that can cause brake failure, including thin or worn brake pads, and clogged brake fluid hoses. The problem that often occurs is overheating in the brake system which causes brake failure (fading). Failed brake events are more common in hilly descent areas, these accidents make brake failure the second most common accident after driver negligence such as drowsiness. One of the efforts to prevent the failure of the brakes to occur is to make a brake safety system on an automatic Arduino Uno motorbike. The method applied includes planning, manufacturing, and testing of tools. This detector uses the DS18B20 sensor as input, Arduino uno as a microcontroller, 16 x 2 LCD as direct monitoring, and the output is an LED light and a buzzer. The working principle of this tool is that the temperature of the brake calipers has started to heat up, so the DS18B20 sensor works by generating data that will be displayed on the LCD, and when it reaches the temperature limit of 100 degrees Celsius at the same time the buzzer sounds and the LED light turns on and the water pump functions which will spray part of the system. braking. During the heating process, the temperature will be monitored via the LCD display on the vehicle. The test results of this tool will be affected by the hot temperature of the DS18B20 sensor.

Published: February 2023

In situ desorption gas measurement can be used to evaluate shale gas potential, sweet spot prediction, and production strategy optimization. However, gas contents and carbon isotope compositions of in situ desorption gas and the relationship to reservoir properties and shale compositions are not systematically studied from the actual production situation. In this study, 63 core shales of Wufeng-Longmaxi formation from the YY1 well in the eastern Sichuan Basin were subjected to TOC (total organic carbon), solid bitumen reflectance (Rb), maceral fractions of kerogen analysis, and X-ray diffraction (XRD) analysis to obtain shale compositions, and 10 selected samples were conducted on low-pressure N2/CO2 (N2/CO2GA), mercury injection capillary pressure (MICP), and field emission scanning electron microscopy (FE-SEM) tests to acquire reservoir properties. Meanwhile, 60 samples were also subjected to in situ desorption tests to obtain shale gas content, and 5 selected samples were used to investigate variations in shale gas compositions and carbon isotopes during the desorption process. Results indicated that transient rates of shale gas during desorption process are significantly controlled by desorption time and temperature. In terms of in situ desorption process, total gas is divided into desorbed gas and lost gas. Desorbed gas is mainly comprised of CH4, N2, CO2, and C2H6, with desorption priorities of N2 > CH4 > CO2 ≈ C2H6, which are consistent with their adsorption capacities. The δ13CH4 values tend to become heavier during desorption process, varying from -37.7‰ to -16.5‰, with a maximum increase amplitude of 18.8‰, whereas the change of δ13C2H6 value, from -38.2‰ to -34.8‰, is minor. Desorbed gas shows carbon isotope reversals, due to that preferential desorption of 12C-CH4 during desorption process results in δ13C value less negative in CH4. The tested desorbed gas, lost gas, and total gas ranged 0.088 to 1.63 cm3/g, 0.15 to 3.64 cm3/g, and 0.23 to 5.20 cm3/g, respectively. Shale gas content, i.e., desorbed gas and lost gas, is controlled primarily by TOC content and organic matter (OM)-hosted nanometer-size pores. Clay mineral content is negatively correlated with shale gas content, due to that, clay mineral pores are more easily compacted during burial and occupied by water molecules. Compared with shale gas reservoirs in North America, the studied shale reservoir has high brittle mineral content and permeability, which is considered to have great potential of shale gas resource and to be the next commercial development zone in south China.
Dwarf Galaxies United by Dark Bosons
Authors: Pozo Alvaro , Broadhurst Thomas , III George Smoot , Chiueh Tzihong
Published: February 2023

Low mass galaxies in the Local Group are dominated by dark matter and comprise the well studied “dwarf Spheroidal" (dSph) class, with typical masses of 109−10M⊙ and also the equally numerous “ultra faint dwarfs" (UFD), discovered recently, that are distinctly smaller and denser with masses of only 107−8M⊙. This bimodality amongst low mass galaxies contrasts with the scale free continuity expected for galaxies formed under gravity, as in the standard Cold Dark Matter (CDM) model for heavy particles. Within each dwarf class we find the core radius Rc is inversely related to velocity dispersion σ, quite the opposite of standard expectations, but indicative of dark matter in a Bose-Einstein state, where the Uncertainty Principle requires Rc × σ is fixed by Planks constant, h. The corresponding boson mass, mb = h/Rcσ, differs by one order of magnitude between the UDF and dSph classes, with 10−21.4eV and 10−20.3eV respectively. Two boson species is reinforced by parallel relations seen between the central density and radius of UDF and dSph dwarfs respectively, which both match the steep prediction, ρc ∝ Rc−4, for soliton cores in the ground state. Furthermore, soliton cores accurately fit the stellar profiles of UDF and dSph dwarfs where prominent, dense cores appear surrounded by low density halos, as predicted by our simulations. Multiple bosons may point to a String Theory interpretation for dark matter, where a discrete mass spectrum of axions is generically predicted to span many decades in mass, offering a unifying "Axiverse" interpretation for the physical "diversity" of dark matter dominated dwarf galaxies.

Background: The goal of our study was to construct and validate nomograms for the prognosis of elderly primary ocular adnexal lymphoma (POAL) patients from the Surveillance, Epidemiology, and End Results Program (SEER) database.
Methods: We screened the data of POAL patients aged 60 years or older from the SEER database from 2010 to 2015. For the prediction of the cause-special survival (CSS) and the overall survival (OS) at 1, 3, and 5 years in elderly POAL patients, we constructed nomograms. The nomograms were validated by the decision curve analysis (DCA), the area under the curve (AUC), and the calibration curve.
Results: Among 821 enrolled POAL patients from the SEER database, 547 were assigned to the training group and 247 to the validation group. The C-index of the two groups was 0.744 and 0.755 in the OS model, 0.745 and 0.855 in the CSS model. The AUC values of the nomograms for OS were 0.819, 0.785, and 0.767 in the training cohorts and 0.872, 0.789, and 0.755in the validation cohorts at 1, 3, and 5 years, respectively. The AUC values of predicted CSS in the training and validation cohorts at 1, 3, and 5 years were 0.754, 0.772, 0.765 and 0.840, 0.864, 0.791, respectively. The calibration and DCA curves also demonstrated the predictive performances.
Conclusions: Herein, for predicting the CSS and OS in elderly POAL patients, we constructed predictive nomograms using independent risk factors. These nomograms can help clinicians in predicting the prognosis of elderly POAL patients.

Background: Acute lower respiratory tract infections (ALRTIs) among children under five are still the leading cause of mortality among this group of children in low and middle-income countries (LMICs), especially countries in sub-Saharan Africa (SSA). This scoping review aims to map evidence on prevalence and risk factors associated with ALRTIs among children under five years to inform interventions, policies and future studies.
Methods: A thorough search was conducted via four main databases (PubMed, JSTOR, Web of Science and Central). In all, 3,329 records were identified, and 107 full-text studies were considered for evaluation after vigorous screening and removing duplicates, of which 43 were included in this scoping review.
Findings: Findings indicate a high prevalence (between 1.9% to 60.2%) of ALRTIs among children under five in SSA. Poor education, poverty, malnutrition, exposure to second-hand smoke, poor ventilation, HIV, traditional cooking stoves, unclean fuel usage, poor sanitation facilities and unclean drinking water make children under five more vulnerable to ALRTIs in SSA. Also, health promotion strategies like health education have doubled the health-seeking behaviours of mothers of children under five years against ALRTIs
Conclusion: ALRTIs among children under five still present a significant disease burden in SSA. Therefore, there is a need for intersectoral collaboration to reduce the burden of ALRTIs among children under five by strengthening poverty alleviation strategies, improving living conditions, optimising child nutrition, and ensuring that all children have access to clean water. There is also the need for high-quality studies where confounding variables in ALRTIs are controlled.

Increasing evidence suggests that plant invasions are promoted by altered plant-soil interactions. However, we still lack studies exploring differences in the effects of invasive and native species on soil properties, and particularly studies that would control for species phylogeny and abundance. Here, we grew seven congeneric pairs of invasive and native species with comparable cover in the studied region in a 12-weeks garden experiment. We analysed the amount of nutrients, pH and composition and amount of soil biota in soils cultivated by each species and in uncultivated soil. Then we used ratios of the soil characteristics in cultivated and uncultivated soil to express species effects on the soil. Invasive species used more phosphorus from the soil and supported mycorrhizal communities with higher potential to colonize plant roots than native species, but did not differ in any other soil properties. In contrast, we found strong differences among plant genera and genera from the same families tended to cluster together in their effects on the soil. We also found many interactions of genera and invasion status. Effects of plants on the soil were also largely determined by plant biomass production independent of species identity. The results suggest that invasive and native species differ only in a few general effects on the soil and that the differences among native and invasive species are largely genus specific. They also indicated that species phylogenetic identity and individual plant biomass should be considered in future studies of the effect of plants on the soil.

Published: February 2023

Background: Acute myeloid leukemia (AML) is considered a costly disease. Although induction of remission is a critical factor for overall survival (OS) in patients with AML, the fundamental decision after induction is the best post-remission treatment strategy. Depending on risk stratification, the patient may receive consolidation with cycles of intermediate doses of cytarabine, auto-HSCT or allo-HSCT, according to the availability of each service and the availability of a compatible donor. Both strategies are valid for low-risk AML and in the impossibility of an allogeneic or haploidentical transplant also for intermediate risk. Literature data indicate that the safety and effectiveness of consolidation therapy with intermediate dose cytarabine or auto-HSCT do not differ from each other, and the cost can help physicians and health managers in their choice.
Methods: We aimed to compare the cost of both treatments of second consolidation in adult patients with de novo AML, 18 - 60 years old, included in the ICAML (International Consortium of Acute Myeloid Leukemia) protocol and analyzed through the microcosting methodology, estimating the direct medical costs of the alternative consolidation therapies under analysis.
Results: Retrospectively, from 09/01/15 to 09/01/19, we analyzed 9 patients from the Hospital das Clínicas de Ribeirão Preto, 5 patients treated with auto-HSCT, and 4 patients treated with intermediate doses of cytarabine. The average cost of auto-HSCT was BRL 114.212,78, and that of cytarabine was BRL 121.980,93.
Conclusion: In both groups and regardless of the treatment cycle, we observed that the inputs with the greatest economic impact were hospital admissions, mainly due to infections

Background:
Familial Hypercholesterolemia (FH) is a genetic disorder in lipoprotein metabolism caused by mutations that increase LDL and total cholesterol levels. High LDL and cholesterol levels increase atherosclerosis risk. FH mutations impact the LDL receptor (LDLR) gene, apolipoprotein B, and PCSK9. About 20% of FH cases have a polygenic basis that affects LDL levels. We decided to conduct a systematic review of the available research in this field to provide a thorough genes/proteins network meta-analysis on the impact of drug combinations on the management of heterozygous Familial Hypercholesterolemia (HeFH). This paper reviews and analyzes the literature on the effects of medication combinations on HeFH management. This study investigates articles that analyzed the management and adjuvants of HeFH to recommend forceful drug combinations.
Methods:
This systematic review and network meta-analysis analyzed the Science Direct, Embase, Scopus, PubMed, Web of Science (ISI), and Google Scholar databases without a lower time limit and up to July 2022. The current study consists of three fundamental stages. Firstly, drug combinations are recommended by reinforcement learning. In the second stage, we used a systematic review to analyze RL's outcomes in diverse populations (with a variety of ages, sex, etc.). Natural Language Processing (NLP) employs context to search these articles. We contrasted manual and NLP-based searches and discovered that NLP could find articles based on MeSH, not simply words. In stage three, we analyze RL outcomes using network meta-analysis.
Results:
This study uses the RAIN method to investigate the most effective medication combination for managing Heterozygous Familial Hypercholesterolemia (HeFH). Results from the method indicate that the best-recommended scenario is 2.7 times more efficient than the prescription of Ezetimibe as the initial scenario.
Conclusion:
Our systematic review and network meta-analysis review indicate that a drug combination of Ezetimibe, Pravastatin, and Simvastatin is highly effective. However, additional high-quality clinical trials are required to determine the efficacy and safety of other treatments.

Background/objectives: To examine the correlation between Humphrey visual field analyzer and an automated virtual reality perimetry test (Oculera visual field analyzer) in glaucoma patients and healthy individuals.
Methods: This prospective, single-center study was conducted on 93 eyes of 93 patients, 55 of whom were glaucoma patients (glaucoma group) and 38 healthy subjects (normal group). HFA II (24-2, Swedish Interactive Threshold Algorithm) and Oculera (24-2, Oculera Interactive) tests were applied to all participants. Mean deviation (MD) values ​​of both devices were analyzed. The correlation between the two devices was assessed with statistical analyses on MD. The Bland-Altman plot was used to display the level of agreement between the two devices.
Results: The MDs were -6.36 dB (-31.8 to 2.27) for HFA II MD and -5.80 dB (-29.1 to 2.2) for Oculera MD. The difference between MDs of Oculera and HFA II was -0.56 dB. Dependent t-test showed a statistically significant difference between Oculera and HFA II (mean -0.55; 95% CI -0.885 to -0.229; p < 0.001). Also, the correlation of MDs was quite strong (r = 0.995 and p < 0.001). In the subgroup analysis, comparable results were observed with both devices in all three groups among mild, moderate, and advanced glaucoma patients.
Conclusions: A good correlation was found between standard automatic perimetry and Oculera. Oculera MD results were comparable to HFA II MD results. Oculera may be a useful alternative in clinical practice for functional testing in glaucoma patients. It also offers convenience as it is portable and can be applied at home.
