Authors: Yang Qinfeng , Huang Yuzhi , Chen Yuhang , Li Kunlian , Gan Wei , Shi Zhanjun , Wang Jian
Published: February 2023

Introduction: Hypothyroidism is a common disease in the US population. The impact of hypothyroidism on perioperative complications of total hip arthroplasty is poorly understood. To examine risk factors and hospitalization costs in patients with hypothyroidism after total hip arthroplasty (THA) using a large-scale sample national database. Methods: A case-control study was performed based on the National Inpatient Sample (NIS) database from 2005 to 2014. With the use of propensity scores, patients with hypothyroidism were matched in a 1:1 ratio to those without hypothyroidism by age, gender, race, Elixhauser Comorbidity Index (ECI), and insurance type. Patient demographics, postoperative complications, length of stay (LOS), and hospital costs were compared between matched cohorts. Short-term complication rates after THA were compared using multivariate logistic analysis. Results: The proportion of patients with hypothyroidism receiving THA was 12.97%. Linear regression analysis yielded that patients with hypothyroidism receiving THA were more likely to have postoperative acute anemia (odds ratio = 1.15; 95% confidence interval = 1.12–1.18) and higher mean hospital costs compared to the non-hypothyroid cohort. Conclusions: This present study demonstrates that hypothyroid patients undergoing THA have a higher risk of short-term complications. Furthermore, it significantly increased the total cost of hospitalization, which deserves more attention from orthopedic surgeons.
Hospitalization Rates Following mRNA SARS-CoV-2 Booster Vaccination among Patients with and without Prior SARS-CoV-2 Infection: A Nationwide, Retrospective Cohort Study
Authors: Zheng Chunlei , Branch-Elliman Westyn , Fillmore Nathanael R , Monach Paul A
Published: February 2023

Background
We previously reported a transient increased risk of hospitalization after mRNA vaccination among patients with prior SARS-CoV-2, absolute risk ~ 1:1000. Here, we extend and expand this analysis to evaluate the impact of prior infection on hospitalization after a third (booster) dose.
Methods
Nationwide, retrospective cohort study of hospitalization among US Veterans who received a third dose of mRNA vaccine between 7/1/2021-2/28/2022. Daily rates of incident hospitalization were compared before and after booster doses, stratified by history of SARS-CoV-2.
Results
1,632,806 patients received a third dose, including 90,174 with a history of SARS-CoV-2 infection. Hospitalization rates were unchanged before and after the booster dose among patients with (112.3/100,000 post-dose versus 100.2/100,000 pre-dose, p = 0.24) or without previous infection (32.1/100,000 post-dose versus 31.3/100,000 pre-dose, p = 0.71). Among 241 patients hospitalized after receipt of the initial vaccination, 90 received a booster, and none of these 90 patients were hospitalized.
Conclusions
There was not convincing evidence for increased hospitalizations shortly after booster vaccines, including in patients with a history of SARS-CoV-2 infection who required hospitalization after their initial vaccine. The size and design of the study prevent strong conclusions about absence of risk.

Published: February 2023

Quantum computing has shown great potential in various quantum chemical applications such as drug discovery, material design, and catalyst optimization. Although significant progress has been made in quantum simulation of simple molecules, ab initio simulation of solid-state materials on quantum computers is still in its early stage, mostly owing to the fact that the system size quickly becomes prohibitively large when approaching the thermodynamic limit. In this work, we introduce an orbital-based multi-fragment approach on top of the periodic density matrix embedding theory, resulting in a significantly smaller problem size for the current near-term quantum computer. We demonstrate the accuracy and efficiency of our method compared with the conventional methodologies and experiments on solid-state systems with complex electronic structures. These include spin polarized states of a hydrogen chain (1D-H), the equation of state of a boron nitride layer (h-BN) as well as the magnetic ordering in nickel oxide (NiO), a prototypical strongly correlated solid. Our results suggest that quantum embedding combined with a chemically intuitive fragmentation can greatly advance quantum simulation of realistic materials, thereby paving the way for solving important yet classically hard industrial problems on near-term quantum devices.
DOMESTIC AND EUROPEAN EXPERIENCE IN ACCOUNTING AND TAXATION OF BIOLOGICAL ASSETS
Authors: Kravchenko О. , Diakova V.
Published: February 2023

In modern conditions, domestic agricultural products are not inferior in quality to other countries in the world that export similar goods. In addition, in recent years, Ukraine has been a leader in world rankings in the number of exported goods from the agricultural industry, which indicates an increase in agricultural potential. Thus, the main assets of enterprises engaged in the cultivation of agricultural products of crop and / or livestock are biological assets. Whereas comprehensive, objective and timely information about their condition in the enterprise is necessary for the successful development of the enterprise economy in market conditions.
This study is designed to analyze the theoretical aspects of accounting (valuation, recognition) of biological assets in Ukrainian enterprises and to assess a similar area abroad. Thus, for the analysis of domestic experience, the works of scientists who determined the genesis of the concept of "biological assets", classified biological assets by individual characteristics, investigated the advantages and disadvantages of recognizing biological assets at fair or original value, etc. were evaluated. While the source for determining the specifics of taxation of biological assets were regulations, in particular the Tax Code of Ukraine. With regard to the study of foreign experience, for the representativeness of the study was a selection of scientific papers based on the scientometric database Scopus. This analysis will highlight the most cited articles in the field of "biological assets", which in turn indicates the quality of work and the practical significance of the presented results. As a result of such a study, it became known that the most relevant topic among foreign scientists is the assessment of biological assets, while the taxation of such assets is reflected in the overall set of financial results for the calendar year. Based on the analysis of foreign experience, it was determined that the problems with the accounting and taxation of biological assets are not unique to Ukrainian accounting, various problem areas can be traced in Latvia, Estonia, the Czech Republic, etc.
Based on the study, the problematic aspects of the application of fair value in Ukraine and alternative options for taxation of agricultural activities were identified. While the analysis of foreign experience confirmed the need to comply with regulatory requirements in order to increase the financial condition of the enterprise.
Investments support for Sustainable Development Goal 7: Research gaps in the context of post-COVID-19 recovery
Authors: Makarenko Inna , Bilan Yuriy , Streimikiene Dalia , Rybina Larysa
Published: February 2023

Successful achievement of the 17 Sustainable Development Goals (SDGs), including SDG 7: Affordable and Clean Energy, is impossible without proper financial support, especially after the devastating impact of the COVID-19 pandemic. Despite more than million academic papers related to SDG 7, only very few of them address the financial aspects of achieving SDG 7. To test the hypothesis, “SDG 7 related academic studies ignore the issue of investment in general and responsible investment in particular”, a meta-analysis is performed that includes a number of specific instruments and technics such as SciVal by Elsevier, VosViewer, Google trends, Google Books Ngram Viewer and Google Data. The results show a lack of appropriate academic support (methodology, empirical results, econometric models etc.) for practitioners to fill the existing financial gap and successfully achieve SDG 7. Among 1.2 million SDG 7 related papers, less than 100 deal with the financial gap problem measured by trillions of dollars in achieving SDG 7. This paper identifies the most promising and relevant topics for study related to SDG 7 and investment: the impact of the pandemic on decisions in the energy sector; efficiency of SDG 7 investment support and methodology for its assessment; green bonds, green loans, sovereign green bonds as responsible investment tools to advance SDG 7.

Między przebojowością a wycofaniem. Czy współczesny świat jest zbyt nieprzyjazny dla ludzi nieśmiałych?
Authors: Pospiszyl Irena
Published: February 2023

Wielu badaczy wskazuje na pewien paradoks dotyczący wymagań wobec współczesnego człowieka. Z jednej strony oczekujemy żeby był on asertywny, samodzielny, społecznie kompetentny i łatwo przystosowujący się do nowych sytuacji. W takich warunkach podstawowym mechanizmem radzenia sobie w świecie społecznym jest jego własna atrakcyjność, umiejętność zaciekawienia sobą, odnalezienia tego, co wspólne, współbrzmienia z innymi. Z drugiej zaś strony, współczesny świat ze swoim galopującym tempem życia, zmiennością warunków i koniecznością nadążania za pojawiającymi się wyzwaniami powoduje u ludzi wzrost poczucia zagubienia, skłonności do wycofywania się i stanowi niezwykłe wyzwanie dla osób nieśmiałych.

Artykuł traktuje o problemach jednostek nieśmiałych w tym wymagającym współczesnym świecie oraz ukazuje sprzeczność pomiędzy oczekiwaniami a stwarzanymi warunkami do ich realizacji.
The experience of conflicts (internal and external) and the sense of meaning in life. An existential approach
Authors: Rumianowska Agnieszka
Published: February 2023

Although there is a relatively long tradition of research into the mechanisms underlying conflicts (both internal and interpersonal ones), the existential perspective of conflict has not as yet been the subject of extensive psychological studies. From the standpoint of existential psychology, conflict is primarily an expression of an individual’s confrontation with objective existential facts: freedom and the responsibility for oneself that freedom entails, the finitude of human life, existential loneliness and fate in its broadest sense. Although conflict, so defined, is essentially an immanent feature of human existence, it becomes a problem when a strong sense of helplessness and anxiety starts to accompany it, as a person loses their purpose in life and fails to realize their personal values.

This research aimed to answer the question of whether there is a relationship between an individual’s behavior in response to (internal and interpersonal) conflict and his/her sense of meaning in life and preferred values. The study covered a group of 153 students aged from 19 to 26 years. Purpose-of-life was measured using the test developed by Crumbaugh and Maholick (1964). The Schwartz Portrait Values questionnaire was used to assess the respondents’ preferences for fundamental values. The behavior of the subjects in response to conflict was examined using linguistic (frequency) analysis of the verbs used in their open-ended answers.
In Vitro Effects of Bisphenol Analogs on Immune Cells Activation and Th
Differentiation
Authors: Pahović Pia Štrukelj , Iulini Martina , Maddalon Ambra , Galbiati Valentina , Buoso Erica , Dolenc Marija Sollner , Corsini Emanuela
Published: February 2023

Aims:

Investigate the immunomodulatory effects of bisphenols in the THP-1 cell line
and peripheral blood mononuclear cells in response to lipopolysaccharide (LPS) activation or to
phorbol 12-myristate 13-acetate (PMA) and ionomycin.

Background:

We have previously demonstrated the usefulness of the evaluation of RACK1 expression
as a link between endocrine disrupting activity and the immunotoxic effect of xenobiotics. We
demonstrated that while BPA and BPAF reduced RACK1 expression, BPS was able to increase it.

Objective:

Bisphenol A (BPA) is one of the most commonly used chemicals in the manufacturing
of polycarbonate plastics and plastic consumer products. Its endocrine disrupting (ED) potential and
changes in European regulations have led to replacing BPA in many uses with structurally similar
chemicals, like bisphenol AF (BPAF) and bisphenol S (BPS). However, emerging data indicated
that bisphenol analogues may not be safer than BPA both in toxic effects and ED potential.

Methods:

THP-1 cell line and peripheral blood mononuclear cells were activated with lipopolysaccharide
(LPS) or with phorbol 12-myristate 13-acetate (PMA) and ionomycin.

Results:

BPA and BPAF decreased LPS-induced expression of surface markers and the release of
pro-inflammatory cytokines, while BPS increased LPS-induced expression of CD86 and cytokines.
BPA, BPAF, and BPS affected PMA/ionomycin-induced T helper differentiation and cytokine release
with gender-related alterations in some parameters investigated.

Conclusion:

Data confirm that bisphenols can modulate immune cell differentiation and activation,
further supporting their immunotoxic effects.
Vitamin D and COVID-19 Infection
Authors: Richter Josef , Vetvicka Vaclav , Král Vlastimil , Richterová Stanislava
Published: February 2023

Objective:

The COVID-19 epidemic resulted in a global crisis of public health. Therefore, the possibility of prevention, leading to reduced infection and/or an improved disease state, is the subject of intensive attention. The novelty of this study is the direct evaluation of vitamin D levels with the risk of COVID-19 infection.

Background:

Currently, several nutraceuticals, including vitamin D, beta-glucan, and some minerals, are being studied for their role in stimulating immunity. Our study focused on the relationship between levels of vitamin D in immunodeficient patients and the risk of the development of COVID-19.

Method:

In this study, patients were supplemented with vitamin D.

Results:

In a group of 71 patients, we found that patients with vitamin D levels below 30 ng/ml had an increased risk of COVID-19 development and more severe disease progress. In patients with blood levels over 40 ng/ml, we consistently found high levels of protection against COVID-19 infection.

Conclusion:

The most important finding is that vitamin D levels above 40 ng/ml result in the reduction of risks of serious clinical manifestation of COVID-19 infection.

Published: February 2023

Background:

Mental health is one of the most critical public health issues as it significantly contributes to the global disease burden worldwide.

Objective:

This study aims to assess the mental health status and its determinants among higher socio-economic married working women in Bangladesh.

Methods:

A cross-sectional study was conducted among 560 higher socio-economic married working women in different organizations in Dhaka City from June to November 2019. A semi-structured questionnaire was used to collect the information, and the mental health status was measured using CES-D Scale.

Results:

The odds of poor mental health were eleven times higher in participants that were always overloaded with work [AOR=10.9], more than nine times more likely among those that always had family members expecting the same work as non-working women [AOR=9.4], and eight times more likely in participants that had a lot of challenges from family/relatives/neighbors for pursuing job [AOR=8.2].

Conclusion:

Unfavorable working conditions, work overload,inadequate support from the organization and family have all been linked together to result in poor mental health. Significant efforts and resources are required to conduct both preventative and control programs.

Published: February 2023

Background:

Neonicotinoids (hereafter called “neonics”) are systemic insecticides used for the protection of agricultural crops. However, their dispersion in nature has been the subject of global concern due to reports of adverse effects on some living organisms. One of the applications of neonics in Nigeria is to protect the cocoa cash crop.

Objective:

Previous studies on pesticide-related pollution in Nigeria focused mainly on organochlorines, but research on neonics is sparse, and the knowledge gap needs to be filled. This work aimed at confirming the presence of four neonics, namely, imidacloprid, thiacloprid, acetamiprid, and thiamethoxam, within the Owena River Basin.

Methods:

Neonics were extracted from cocoa-growing soil, river water, and sediments by a modified QuEChERS method, followed by clean-up of the extractant by dispersive solid phase extraction and analysis by an optimized liquid chromatography/tandem mass spectrometry analytical procedure. The overall performance of these developed methods was then evaluated by set criteria.

Results:

The Limit of Detection (LOD) and Limit of Quantitation (LOQ) ranged from 0.0005 to 0.002 μg/g and 0.002 to 0.005 μg/g, respectively. The recovery for the four target analytes exceeded 75% across all matrices from laboratory-prepared samples. It was discovered that the average concentrations of three of the four neonics of interest in the individual media were: 10.34 nmol/g in cocoa-producing soil, 1.03 nmol/g in river sediment, and 1.08 nM (1.08 x 10-3 nmol/g) in surface river water. No imidacloprid was identified in any of these three environmental compartments.

Conclusion:

The concentration of neonics in the river water, i.e., 0.23 µg/L (230 ng/L), is identical to that of the maximum value recommended in the Canadian Water Quality Guidelines for the Protection of Freshwater Aquatic Life.

Published: February 2023

We studied the effect of long-term constant light exposure on the severity and reversibility of morphological changes in the liver of laboratory rats. Modeling of light exposure was carried out by means of 24-hour exposure to artificial light (in the daytime --- 300 lk, at night --- 500 lk). During the study we found that morphological changes in the liver were represented by damage to the parenchyma and circulatory disorders, the degree of which increased with increasing duration of exposure. After providing natural light in the laboratory, gradual recovery of the morphological structure of the organ was observed, which indicates the reversibility of the changes detected. Keywords: light exposure, circadian rhythms, morphology, liver.

Combined use of an immersion agent with low-intensity laser irradiation for optical clearing of skin before plasmon photothermal therapy (PPTT) procedure is offered. Pilot study results of influence of the immersion agents on optical parameters of skin, subdermal connective tissue and model tumor of rats in vivo at hyperthermia during PPTT are presented. Model of alveolar liver cancer --- cholangiocarcinoma, transplanted under the skin, was used as a model tumor. For PPTT the gold nanorods with absorption band in the area of diode laser radiation (808 nm) were introduced. Monitoring of light attenuation coefficient change in skin at optical clearing was performed using optical coherent tomography. Measurements of optical parameters of the complete tumor and its layers were performed using spectrometers in a wave length range of 350-2200 nm. Reduction of skin thermal damage during PPTT with preliminary optical clearing using immersion agent (mixture of 70% glycerol water solution and 10% DMSO) and low-intensity laser irradiation at wave length of 808 nm is observed. Keywords: gold nanorods, IR laser radiation, optical clearing, optical parameters, plasmon photothermal therapy.
Low pressure DBD in He-Ne mixture. Spectroscopy of the Afterglow
Authors: Ivanov V. A.
Published: February 2023

The paper considers the possibility of using a low-pressure dielectric barrier discharge (DBD) as a plasma source for the active medium of a He-Ne-laser. The results of a spectroscopic study of the decay stage of a DBD plasma of a cylindrical configuration with a pronounced inverse population of the upper level of the 2p55s configuration, which makes the line of 632.8 nm one of the brightest in the visible region of the spectrum, are presented. Based on the analysis of data on the populations of the excited levels of the neon atom and the metastable levels of helium 21S0 and 23S1, it is shown that in the early stage of the DBD afterglow at helium pressures of a fraction of a Torr, the distribution of populations over the 2p55s and 2p54d levels of the neon atom, which is characteristic of the excitation transfer mechanism, is realized. In the late afterglow with the departure of helium atoms He21S0, emission in the visible region of the spectrum is formed mainly by transitions from levels of the 2p53p, configuration, the population of which is associated with He(23S1) atoms. At this stage, the population of the 2p55s and 2p54d states by electron-ion recombination processes is ineffective and does not lead to the formation of population inversion. As an optimal solution in terms of the 632.8 nm line brightness in the afterglow, it is proposed to use a discharge with electrodes along the outer surface of a cylindrical discharge tube, initiated at frequencies that exclude the recombination stage of the afterglow. Keywords: elementary processes, barrier discharge, inverse population, afterglow, helium-neon plasma, excitation transfer

Published: February 2023

A formula for calculating the relativistic electron localization function (RELF) within the framework of the Dirac-Fock method is obtained. An approach similar to that used earlier in [A.D. Becke and K.E. Edgecombe, The Journal of Chemical Physics 92, 5397 (1990)] in deriving an expression for the nonrelativistic electron localization function (ELF) is applied. It is demonstrated that the expression for RELF differs from the expression for ELF with replacement of the nonrelativistic electron density by its relativistic counterpart. Relativistic calculations of ELF and RELF for a number of superheavy elements are performed and the results are compared. By several examples it is shown that the ELF value equal to 0.5 does not necessarily correspond to the distribution density of homogeneous electron gas. Keywords: relativistic electron localization function, Dirac-Fock method, superheavy elements, electron gas.

Представлены результаты исследования процессов реактивного магнетронного распыления Ti-Al составной мишени в Ar/O2 смеси газов при различных способах подачи газов в камеру. Установлено, что независимо от способа подачи газов при изменении концентрации кислорода в Ar/O2 смеси газов происходит изменение соотношения содержания Al и Ti в нанесенных пленках Ti1-xAlxOy. На основе исследований диэлектрических характеристик нанесенных пленок Ti1-xAlxOy установлено, что при раздельной газоподаче (Ar подается в область мишени, O2 подается в область подложки) в отличие от совместной газоподачи (смесь Ar/O2 рабочих газов подается в область мишени) возможно нанесение диэлектрических пленок в переходном режиме при сравнительно высоких скоростях распыления. При этом подача кислорода в область подложки позволяет увеличить содержание кислорода в пленках до 60-64 at.%. Ключевые слова: реактивное магнетронное распыление, составная мишень, тонкие пленки, оксид титана-алюминия, элементный состав, диэлектрическая проницаемость, тангенс угла диэлектрических потерь.
Theoretical Grounds of Shared Intentionality for Neuroscience in Devel-oping Bioengineering Systems
Authors: Danilov Igor Val
Published: February 2023

The article discusses a definition of shared intentionality that reflects recent discoveries for inspiring further translational research in developing bioengineering systems based on human-computer interaction. The child's cognition begins through shared intentionality that occurs in child-caregiver interaction when communication via sensory cues is impossible. There needs to be more knowledge on how it appears. This article argues that shared intentionality is collaborative interactions in which participants share the essential sensory stimulus of the actual cognitive problem. This social bond enables ecological training of the immature organism, starting at the reflexes stage of development, for processing the organization, identification, and interpretation of sensory information in developing perception. In nature, shared intentionality appears in mother-child dyads in increasing interpersonal dynamics due to mechanisms of cell coupling that provide an ecological developmental template. Knowledge about neurophysiological processes occurring during pre-perceptual communication can contribute to advances in bioengineering systems.

Published: February 2023

Background

One of the factors influencing health and well-being is dietary patterns. Data on food consumption are necessary for evaluating and developing community nutrition policies. Few studies on Jordanians’ food consumption and dietary habits at various ages have been conducted, despite the increased prevalence of overweight, obesity, and chronic diseases. This will be the first study focusing on Jordanians’ food consumption patterns that includes children, adolescents, adults, and older adults.

Objective

This cross-sectional study aims to describe the design and methodology of the Jordan’s Population-based Food Consumption Survey, 2021-2022, which was developed to collect data on food consumption, including energy, nutrients, and food group intake, from a representative sample of Jordanians and to determine the prevalence of overweight and obesity and their relationship to food consumption.

Methods

Participants were selected by stratified random sampling, using the Estimated Population of the Kingdom by Governorate, Locality, Sex, and Households, 2020 as the sampling frame. The food consumption survey sample was at the population level, representing gender and age classes (8-85 years old). The data collection period was 6 months. Food consumption was assessed using 24-hour dietary recall (2 nonconsecutive days, 1 week apart) interviews representing weekdays and weekends. In addition to data on food consumption, information on the use of food supplements, sociodemographic and socioeconomic status, and health was gathered. Weight, height, and waist circumference were all measured.

Results

The survey included 632 households with 2145 participants, of which 243 (11.3%) were children, 374 (17.4%) were adolescents, 1428 (66.6%) were adults, and 99 (4.6%) were older adults. Three food consumption databases were used to stratify the mean 24-hour dietary recall food consumption into energy intake, carbohydrates, proteins, fats, fiber, vitamins and minerals, and food groups. BMI was calculated and classified as normal, overweight, or obese. Central obesity was classified as normal or abnormal based on the waist-to-height ratio. The survey results will be disseminated based on age, energy, nutrient, and food group consumption. The prevalence of overweight and obesity by age group will be presented, as well as a comparison to the situation in Eastern Mediterranean countries.

Conclusions

The survey data will be helpful in nutritional studies, assessing changes in dietary patterns, and developing and evaluating nutrition or health policies. It will be a solid base for developing a future national surveillance system on food consumption patterns with comprehensive food consumption, physical activity, biochemical, and blood pressure data.

Background

Height-adjusted total kidney volume (htTKV) measured by imaging defined as Mayo Imaging Class (MIC) is a validated prognostic measure for autosomal dominant polycystic kidney disease (ADPKD) in adults to predict and stratify disease progression. However, no stratification tool is currently available in pediatric ADPKD. Because magnetic resonance imaging and computed tomography in children are difficult, we propose a novel 3D ultrasound-based pediatric Leuven Imaging Classification to complement the MIC.

Methods

A prospective study cohort of 74 patients with genotyped ADPKD (37 female) was followed longitudinally with ultrasound, including 3D ultrasound, and they underwent in total 247 3D ultrasound assessments, with patients' median age (interquartile range [IQR]) at diagnosis of 3 (IQR, 0–9) years and at first 3D ultrasound evaluation of 10 (IQR, 5–14) years. First, data matching was done to the published MIC classification, followed by subsequent optimization of parameters and model type.

Results

PKD1 was confirmed in 70 patients (95%), PKD2 in three (4%), and glucosidase IIα unit only once (1%). Over these 247 evaluations, the median height was 143 (IQR, 122–166) cm and total kidney volume was 236 (IQR, 144–344) ml, leading to an htTKV of 161 (IQR, 117–208) ml/m. Applying the adult Mayo classification in children younger than 15 years strongly underestimated ADPKD severity, even with correction for height. We therefore optimized the model with our pediatric data and eventually validated it with data of young patients from Mayo Clinic and the Consortium for Radiologic Imaging Studies of Polycystic Kidney Disease used to establish the MIC.

Conclusions

We proposed a five-level Leuven Imaging Classification ADPKD pediatric model as a novel classification tool on the basis of patients' age and 3D ultrasound-htTKV for reliable discrimination of childhood ADPKD severity.

Background

Statins are the third most prescribed drug class in kidney transplant recipients as cardiovascular disease is the leading cause of death in this population. However, statins' safety profile remains unclear in kidney transplant recipients who are uniquely burdened by concomitant immunosuppression and comorbidities. We conducted a national study to characterize the association of statin use with adverse events in kidney transplant recipients.

Methods

We studied adult (18 years or older) single-organ kidney transplant recipients in 2006–2016 with Medicare as primary payer (n=57,699). We used prescription drug claims to capture statin use and International Classification of Diseases 9/10 diagnosis codes to capture statin-related adverse events (post-transplant diabetes mellitus, hemorrhagic stroke, cataract, liver injury, and rhabdomyolysis). We conducted multivariable Cox regression for each outcome with statin use as a time-varying exposure.

Results

Post-transplant diabetes mellitus was the most common outcome (5-year Kaplan–Meier incidence; 43% in statin users versus 35% in nonusers), followed by cataract (22% versus 12%), liver injury (2% versus 3%), hemorrhagic stroke (1.9% versus 1.4%), and rhabdomyolysis (1.5% versus 0.9%). In our multivariable analysis, statin use was associated with higher hazard of post-transplant diabetes mellitus (adjust hazard ratio [aHR], 1.12; 95% confidence interval [95% CI], 1.07 to 1.18), cataract (aHR, 1.22; 95% CI, 1.14 to 1.31), and rhabdomyolysis (aHR, 1.37; 95% CI, 1.10 to 1.71) but lower hazard of liver injury (aHR, 0.82; 95% CI, 0.71 to 0.95). Statin use was not associated with hemorrhagic stroke (aHR, 1.04; 95% CI, 0.86 to 1.26).

Conclusions

Statins seem to be generally well tolerated in kidney transplant recipients. However, statin use might be associated with slightly higher risk of post-transplant diabetes mellitus, cataract, and rhabdomyolysis.
Analysis of Grammar Activities

Published: February 2023

Teaching grammar is becoming very debatable issue in recent days, because as Stephen Krashen (1982) said “there is a great deal of effect on the language use of the learner and this effect is peripheral and fragile”. It is known that there are three different approaches to teaching grammar and they are teaching grammar as a product, teaching grammar as a process and the last one is teaching grammar as a skill, below we will focus on each separately.

Occupational Health Hazards among Garment Industry Workers in Unorganised Sector in Tiruppur
Authors: M Dr. Anish Sharmila , Ramya Dr. M.
Published: February 2023

Abstract: Occupational health risks are a growing challenge for humanity as a whole. The majority of the labour force works in the unorganised or informal sectors, which make up a significant portion of the Indian economy. The occupation employs a large number of people on a daily pay, and these people are frequently exposed to many kinds of dangerous materials, which could eventually lead to occupational diseases in the employees and their families. The work environment in the garment industry, on the other hand, is hazardous and risky for the employees, which causes a number of health issues from many sorts of physical, chemical, ergonomic, and biological risks. In order to assess the safety measures used in the garment industry, this paper measures work environment parameters like lighting, noise, temperature, and humidity. Ergonomic workstations, inadequate ventilation, excessive noise, dust, and the lack of use of personal protective equipment were the main issues faced by the workers in these industries.

Authors: Tauhidah Dian , Rofi'ah Ndzani Latifatur
Published: February 2023

Science process skills are essential skills that students must possess. The science process skills test is needed to facilitate the measurement, so that test instruments are developed. The developed instrument needs to be validated before it is used. The purpose of this study was to validate the science process skills test instrument so that the developed instrument is valid and can be used to measure student abilities. The research was conducted using a quantitative descriptive method. The study population was all biology education students at UIN Walisongo Semarang-Indonesia, with a sample of 75 students selected using a purposive sampling technique. Data were analyzed using Rasch analysis which was divided into several categories, namely map analysis based on the items and research samples, analysis of the suitability of the items, analysis of separation and reliability, and items’ analysis. The results of Rasch's study show that the developed science process skills test for students proves valid. Participating students have fairly even abilities. The results of the validation of the items did not reveal any misconceptions, the questions were on the abilities of the students, and the questions had varying difficulty ranges. The validity of the science process skills test shows that the test instrument can be used to measure students' science process skills. Test instruments can be used as learning evaluation instruments as well as analysis of student problems related to science process skills.
