Authors: An Lingping , Wang Yihao , Zhao Hang , Yu Can , Wang Yanheng , Wang Shuang , Liu Xuebin 
Published: January 2023

Lunar radiometric calibration is used to solve the problem of
consistent radiometric calibration for multiple satellite platforms
and remote sensors. However, the dark level fluctuates when observing
the Moon with a short-wave infrared spectrometer, which seriously
affects the accuracy of lunar radiation data. In this work, we propose
a dynamic space–time dark level correction approach to address the
fluctuation of the dark level. This method employs cold space signals
in space and time dimensions to estimate the dark level for each frame
individually and to reduce errors due to environmental variations.
Experiments on lunar observations at multiple phase angles were
conducted, and the dark level correction results demonstrate that our
proposed method is effective even in the short-wave infrared, and is
also superior to currently existing techniques. For a single-band
(1700 nm) image of the full Moon, the mean background
proportion of the proposed method is 1.00%, which is better than that
of the static dark correction method (2.25%) and linear dark
correction method (5.93%).

Nutritional status, symptom burden, and predictive validity of the Pt-Global web tool/PG-SGA in CKD patients: A hospital based cross sectional study
Authors: Rashid Ishfaq , Tiwari Pramil , D’Cruz Sanjay , Jaswal Shivani 
Published: January 2023

BackgroundDespite not being frequently recognized, malnutrition, a consequence of chronic kidney disease, negatively affects morbidity, mortality, functional activity, and patient’s quality of life. Management of this condition is made more difficult by the dearth of knowledge regarding the symptom burden brought on by inadequate nutritional status. Additionally, there are multiple tools to evaluate nutritional status in CKD; but, Pt-Global web tool/PG-SGA used in oncology, has not been investigated in chronic kidney disease patients. This study aimed to explore the nutritional status, symptom burden and also investigate the predictive validity of Pt-Global web tool/PG-SGA among pre-dialysis diabetic and non-diabetic chronic kidney disease patients.MethodologyThis cross-sectional study was carried out at a renal clinic of a tertiary care public teaching hospital. Nutritional status and symptom burden was evaluated by employing a ‘Pt-Global web tool/PG-SGA’ which is considered as a preeminent interdisciplinary tool in oncology and other chronic catabolic conditions. The predictive validity of the Pt-Global web tool/PG-SGA, referred as overall score for malnutrition was ascertained using Receiver Operating Curves (ROC). The conclusions were drawn using descriptive statistics, correlation, and regression analysis.ResultsIn a sample of 450 pre-dialysis CKD patients, the malnutrition was present in 292(64.9%) patients. Diabetic CKD patients exhibit higher proportion of malnutrition 159(35.3%). The prevalence of malnutrition was exacerbated by eGFR reduction. The overall Pt-Global web tool/PGA-SGA score was significantly influenced by the symptoms of fatigue (81.5%), appetite loss (54.8%), physical pain (45.3%), constipation (31.78%), dry mouth (26.2%), and feeling full quickly (25.8%). The ROC analysis showed that the AUC for the total PG-SGA score was 0.988 (95% CI: 0.976–1.000), indicating that it is a reliable indicator of malnutrition. The sensitivity (84.2%) for identifying malnutrition was low when using the conventional tool cut off score of ≥9. Instead, it was discovered that a score of ≥3 had a greater sensitivity (99.3%) and specificity (44.3%) and was therefore recommended.ConclusionsThis study not only presents empirical evidence of poor nutritional status in CKD patients but also reveals that it is worse in patients with diabetes, hypoalbuminemia, and poorer kidney function (well recognized risk factors for cardiovascular disease). Early diagnosis and management of symptoms contributing malnutrition will reduce mortality and CKD progression. The Pt-Global web tool/PG-SGA total score of 3 or more appears to be the ideal cut off score for identifying malnutrition, which can be utilized by dietician for improving malnutrition.

Introduction
Medulloblastoma (MB) is the most common childhood malignant brain tumor worldwide. Recently, molecular classification was established and started to play a role in the management of MB; however, studies involving molecular defined MB in Southeast Asia have been limited. We aimed to describe, and correlate clinical characteristics and molecular subgroups with therapeutic outcomes of Thai pediatric patients with MB.

Materials and methods
Pediatric MB patients treated at King Chulalongkorn Memorial Hospital in Thailand from 2006 to 2018 were recruited. Patients were classified by clinical characteristics into standard- and high-risk groups, which determined treatment regimen. Retrospectively, available tumor tissues were classified into 3 molecular subgroups using immunohistochemistry: 1) WNT, 2) SHH, and 3) non-WNT/non-SHH. The primary outcome was 5-year overall survival (OS). Risk factors associated with OS were analyzed using cox regression analysis.

Results
Fifty-three Thai pediatric patients with MB were enrolled. The median follow-up time was 60 months. The 5-year OS for all patients, and patients with standard-risk and high-risk were 74.2%, 76.3% and 71.4%, respectively. Tumor tissues of 24 patients were available, of which 23 could be molecularly classified. Two, one and 20 were in the WNT, SHH and non-WNT/non-SHH subtypes with 5-year OS of 100%, 100% and 78.9%, respectively. Using multivariate analysis, the interval of more than 8 weeks between surgery and radiotherapy was significantly correlated with a decrease in the 5-year OS.

Conclusion
Interval between surgery and radiotherapy within 8 weeks was associated with good therapeutic outcomes among Thai pediatric patients with MB. Simplified molecular subtyping combined with clinical characteristics is practical in risk classification of patients with MB in institutes with limited resources.
Racial and ethnic disparities in workers’ compensation claims rates
Authors: Smith Caroline K. , Wuellner Sara , Marcum Jennifer 
Published: January 2023

Background
Workers of color experience a disproportionate share of work-related injuries and illnesses (WRII), however, most workers’ compensation systems do not collect race and ethnicity information, making it difficult to monitor trends over time, or to investigate specific policies and procedures that maintain or could eliminate the unequal burden of WRII for workers of color. The purpose of this study is to apply a Bayesian method to Washington workers’ compensation claims data to identify racial and ethnic disparities of WRII by industry and occupation, improving upon existing surveillance limitations. Measuring differences in risk for WRII will better inform prevention efforts and target prevention to those at increased risk.

Methods
To estimate WRII by race/ethnicity, we applied the Bayesian Improved Surname Geocode (BISG) method to surname and residential address data among all Washington workers’ compensation claims filed for injuries in 2013–2017. We then compare worker and injury characteristics by imputed race/ethnicity, and estimate rates of WRII by imputed race/ethnicity within industry and occupation.

Results
Black/African Americans had the highest rates of WRII claims across all industry and occupational sectors. Hispanic/Latino WRII claimants also had higher rates than Whites and Asian/Pacific Islanders in almost all industry and occupational sectors. For accepted claims with both medical and non-medical compensation, Bodily reaction/overexertion injuries accounted for almost half of the claims during this reporting period.

Discussion
The high rates of injury we report by racial/ethnic categories is a cause for major concern. Nearly all industry and occupation-specific rates of workers’ compensation claims are higher for Black/African American and Hispanic/Latino workers compared to Whites. More work is needed to identify work-related, systemic, and individual characteristics.

Published: January 2023

Abstract
The conversion of palm oil into biofuel is continuing interest in a green alternative fuel. Catalytic hydrocracking palm oil into biofuels was carried out by NiMoO4/activated carbon catalyst. The catalyst was first designed from nanoparticle NiO–MoO3 supported by activated carbon from palm kernel shell and characterized using X-ray crystallography, Fourier transform infrared, and scanning electron microscope with energy dispersive X-ray. The efficiency of the catalyst was evaluated for the conversion of palm oil into biogasoline and kerosene using the hydrocracking process at different temperatures (150, 250, and 350°C). The resulting catalytic hydrocracking is liquid biofuels, which is analyzed using GC–MC to determine its fractions: biogasoline (C5–C10) and kerosine (C11–C16). The optimum condition of catalytic hydrocracking was obtained at a temperature of 150°C resulting in two primary fractions classified into biogasoline (37.83%) consisting of n-nonane (C9) and 1-heptene (C7) and kerosine (61.34%) consisting of three primary fractions, n-pentadecane (C15), hexadecene (C16), and 1-undecene (C11). The result of this study proved that the NiMoO4/activated carbon catalyst plays an important role in catalytic hydrocracking and becomes a promising alternative catalyst for the preparation of biofuels.
Thermal, mechanical and dielectric properties of glass fiber reinforced epoxy-lanthanum manganite nanocomposites
Authors: Paul Chiriyankandath Preseetha , Varghese Soney 
Published: January 2023

Abstract
The mechanical, thermal and dielectric properties of lanthanum manganite (LaMnO3) epoxy nanocomposites reinforced with silane coated E-glass fiber are reported. Structural and morphological characteristics of the LaMnO3, synthesized by the solution combustion method, were studied via X-ray diffraction, EDAX and scanning electron microscopy. LaMnO3/epoxy composites containing various percentages of LaMnO3 (LME) were prepared via hand lay-up method and tested for tensile, flexural and impact strength. Improved properties were obtained with the addition of LME compared to plain epoxy composites. The thermal stability of the composites remains almost unaltered by the filler loading. Variation in the dielectric characteristics with filler loading is attributed to the percolation of charge carriers due to the interfacial zonal overlapping in the nanocomposite resulting in a change of the dielectric characteristics.
The Information Seeking Behaviors and Needs of Suicide Survivors During Bereavement
Authors: Zimmerman Margaret Sullivan 
Published: January 2023

Abstract
The suicide of one person impacts 60 people, known as suicide survivors. These survivors are at an increased risk for negative mental health outcomes including PTSD, suicidal ideation, and suicide contagion. Despite these consequences, there have not been any information science studies that have explored the information behaviors of people who have recently survived the suicide of a loved one. This article takes a unique approach in combining autoethnography with traditional survey research. One hundred and ninteen participants sourced from a private Facebook suicide bereavement group responded to a survey asking them about their information-seeking after a loved one committed suicide. The qualitative data were fragmented and grouped into like-responses and thematic codes that gave explanation to the research questions. These results are coupled with the author’s ethnographic recounting of a similar experience. Brenda Dervin’s sense-making is employed as the methodological lens through which the study is conducted. It is found that suicide survivors are highly unlikely to have their informational needs met. In the immediate aftermath of their loss, they are most likely to look for information related to the suffering of the deceased. As time passes, they begin to look for information about coping with their loss and preventing suicide of other people; either those close to them or in a larger community scale. Being a survivor motivated many participants to advocacy work. Finally, the author argues that the findings of this article should compel further research and the creation of information policy to aid survivors and prevent suicide contagion.
Compactness Principles for Topological Vector Spaces
Authors: Robdera Mangatiana A. 
Published: January 2023

Abstract
We show that the many of the canonical quantifications of interrelated concepts, centered around compactness in the setting of metric spaces, can be easily generalized to the setting of topological linear spaces. Among other things, we obtain a generalization of the Hausdorff Total Boundedness Principle, of the Grothendieck Compactness Principle, as well as of the Convex Compactness Principle for topological vector spaces.

Authors: Hoyt-Austin Adrienne E. , Cheng Jessica H. , Moua Hana , Tancredi Daniel J. , Chantry Caroline J. , Kair Laura R. 
Published: January 2023

OBJECTIVES
Low-income, first-time mothers generally breastfeed exclusively and, overall, for a shorter average duration than high-income, multiparous mothers. A potential barrier to breastfeeding success is access to a breast pump for home use. In this pilot study, we estimated the effect of providing a manual breast pump during birth hospitalization for home use on any/exclusive breastfeeding and investigated participant attitudes about manual pumps and their breastfeeding experiences.

METHODS
Sixty low-income, first-time mothers were enrolled in a pilot randomized controlled trial. One-half received a manual breast pump and the other half received an attention control. Breastfeeding exclusivity, duration, and use of the manual pump were assessed at 6 and 12 weeks. Qualitative interviews regarding the breastfeeding experience were completed. Thirty-one women answered 13 questions that were then transcribed, coded, and grouped into themes.

RESULTS
Participants who were randomized to manual breast pump receipt during birth hospitalization had increased manual pump use at 6 weeks (13/19 [68%] versus controls 5/17 [29%]), there was no effect of pump receipt on any nor exclusive breastfeeding at 12 weeks. In qualitative analysis of the overall breastfeeding experience, participants expressed a need for additional support and had conflicting attitudes regarding breastfeeding and the pumping experience.

CONCLUSIONS
Manual breast pump receipt in hospital among low-income, first-time mothers did not affect breastfeeding exclusivity or duration. Participants reported that early and ongoing lactation support is essential. Strategies to improve breastfeeding outcomes low-income, first-time mothers are needed.

Published: January 2023

AbstractThe aim of this study was to determine the frequency of carbapenem resistant Klebsiella pneumoniae (CRKP) sequence types (STs) in Iran. Samples were collected from three university hospitals in Sanandaj, Iran, from December 2016 to March 2018. Antibiotic susceptibility testing, phenotypic and genotypic detection of carbapenemases were performed. Common K. pneumoniae capsular types were sought for all isolates. The genetic relatedness of isolates was investigated by multilocus sequence typing (MLST). Plasmids were detected by PCR-based Replicon Typing (PBRT). During the study, 67 K. pneumoniae isolates were identified. Of which, 18 (26.9%) isolates were detected as carbapenem-resistant. The most effective antibacterial agent was tigecycline (97%, 65 isolates) followed by imipenem and ertapenem (73.13%, 49 isolates). PCR showed that 13 isolates (19.4%) had blaNDM-1 gene and 5 (7.5%) harbored blaOXA-48. Examination of common capsular types showed that 2 isolates had K2 and 2 others had K54. REP-PCR revealed 10 clones and 11 singleton strains. MLST analysis of CRKP found ST15 as the most common type (13 isolates, 72.2%), but other STs were also detected namely, ST19, ST117, ST1390, and ST1594. ColE1 and IncL/M plasmids were the carriers of blaNDM-1 and blaOXA-48, respectively. The results showed that CRKP spread in our health centers. Our results, therefore, indicate a worrying trend of resistance to carbapenems in K. pneumoniae.

Published: January 2023

AbstractThe paper compares different metaheuristics for using heat exchangers as a benchmark to estimate the best design parameter values using optimization efficient algorithms. Many MATLAB algorithms are used in this study. Also, an engineering equation solver, which is commercial software, is used to solve the issue. The design calculates three variables, which are the length, and inner and outer pipe diameter of the heat exchanger. The results showed that the best algorithms are particle swarm optimization, and when using this algorithm, the optimal design of the double pipe heat exchanger is as follows: the pipe length is 5.6734·10−1 m, the pipe inner diameter is 8.0203·10−3 m, and the pipe outer diameter is 2.2439·10−2 m.
Czy Nowy Testament mógłby powstać bez Septuaginty?
Authors: Malina Artur 
Published: January 2023

The New Testament texts depend on the Septuaginta translation for the grammar and vocabulary that they use. The influence is shown by the numerous quotations according to the most ancient translation of the Old Testament. The relationship between the two main parts of the Bible lies in the common content shared by the authors of their books. The present paper describes the dependence of the name “New Testament” on the Septuagint and demonstrates that its openness favored the reception of the Christian message.
Interim Analysis of Treatment Outcomes of Young Children with 5q Spinal Muscular Atrophy on Gene Replacement Therapy with Onasemnogene Abeparvovec. Clinical Observations
Authors: Kokorina Anna A. , Nikitin Sergei S. 
Published: January 2023

Background. Onasemnogene abeparvovec is the first gene replacement therapy medication based on the adeno-associated viral vector (AAV9). One injection to a patient with 5q spinal muscular atrophy (SMA) leads to replacement of the missing or defective SMN1 gene with its functional copy. It leads to normalization of survival motor neuron protein (SMN) production.Objective. The aim of the study is to evaluate efficacy, safety, and causes of different responses to therapy after single administration of onasemnogene abeparvovec in 5 patients with 5q SMA (types I and II) comparing the baseline status with the results of continued monitoring in real clinical practice in Russian Federation.Methods. Interim results of continued follow-up of children with 5q SMA with 2–3 copies of the SMN2 gene are presented: 2 boys and 1 girl with type I who received single dose of onasemnogene abeparvovec at 4 and 7 months of age; and 2 girls with type II who received therapy at 11 and 16 months of age.Results. Short-term controlled fever was observed in 4 out of 5 patients during first 2 weeks after viral vector therapy administration (max in patient 5 — up to 38.5 ° C). All 5 children had transaminases increase, 1 patient — significant transaminases increase during the sensitisation period (> 10 from upper normal level (UNL)), 1 patient — delayed significant transaminases increase (> 20 UNL), 1 patient — transaminases increase (> 3 UNL) after discontinuation of longterm therapy with glucocorticosteroids (according to prescribing information). All patients had shown positive and sustained response to therapy over time at motor status assessment via CHOP INTEND / HFMSE scales. The more significant response was observed in patients with less aggressive baseline 5q SMA type II with 3 copies of the SMN2 gene.Conclusion. Onasemnogene abeparvovec is relatively safe medication for management of children with 5q SMA. Thus, the development of adverse events and their mechanisms should be further studied, as well as long-term follow-up of recipients is required to gather knowledge on this medication effects on human body.

Background. Alfa-mannosidosis is ultra-rare autosomal recessive lysosomal storage disease caused by the mutation in the MAN2B1 gene. Pathogenic nucleotide variants and structural changes in this gene lead to acid alpha-mannosidase deficiency, this enzyme is involved in oligosaccharides degradation. This disease is characterized by multisystem involvement and chronic progressive course.Clinical case description. The clinical case attracted our attention due to the late disease diagnosis in a boy living in a metropolis. The child has classic clinical manifestations of the disease: typical phenotype, spinal deformity, developmental speech and motor delays, hearing loss, hepatomegaly, splenomegaly, umbilical and inguinal hernias. Despite developmental speech delay and frequent recurrent otitis, the patient has not been referred to surdologist examination until the age of 4.5 years. Intriguing fact is the presence of congenital cataract that was the reason for surgery twice.Conclusion. Congenital cataract is one of the early manifestation of this disease. 3 out of 8 patients with alfa-mannosidosis observed in our centre had congenital cataract. We assume that such patients should be referred to genetics for the early exclusion of alpha-mannosidosis. Late diagnosis and progressive course of the disease led to early disability of the patient. Nowadays, as enzyme replacement therapy is available, it is crucial to identify these patients timely in order to improve their quality of life and increase survivability.
