Background
The cause for differences in serum creatinine between Black and non-Black individuals incorporated into prior GFR-estimating equations is not understood. We explored whether social determinants of health can account for this difference.

Methods
We conducted a secondary analysis of baseline data of the Modification of Diet in Renal Disease and Chronic Renal Insufficiency Cohort studies (N=1628 and 1423, respectively). Data in both study cohorts were stratified by race (Black versus non-Black). We first evaluated the extent to which the coefficient of Black race in estimating GFR from creatinine is explained by correlations of race with social determinants of health and non-GFR determinants of creatinine. Second, we evaluated whether the difference between race groups in adjusted mean creatinine can be explained by social determinants of health and non-GFR determinants of creatinine.

Results
In models regressing measured GFR on creatinine, age, sex, and race, the coefficient for Black race was 21% (95% confidence interval, 0.176 to 0.245) in Modification of Diet in Renal Disease and 13% (95% confidence interval, 0.097 to 0.155) in the Chronic Renal Insufficiency Cohort and was not attenuated by the addition of social determinants of health, alone or in combination. In both studies, the coefficient for Black race was larger at lower versus higher income levels. In models, regressing creatinine on measured GFR, age, and sex, mean creatinine was higher in Black versus non-Black participants in both studies, with no effect of social determinants of health.

Conclusions
Adjustment for selected social determinants of health did not influence the relationship between Black race and creatinine-based estimated GFR.

Published: February 2023

Mucocutaneous complications or adverse events due to SARS-CoV-2
infection or vaccination have been well-delineated in the literature,
respectively. Most eruptions are considered to be mild and
self-limiting; however, for the atypical cases which have a tentative
clinical diagnosis, performing a biopsy and histopathological assessment
is pivotal to confirm the diagnosis and subsequently prescribe a more
tailored treatment. Despite the diverse reporting of such incidents
globally, the rate of biopsied cases is restricted to less than 15% in
most studies. This case series elucidates 20 patients referred to the
tertiary dermatology clinic, including 14 COVID-19 infection-related
eruptions such as Lichen Planus (LP), Cutaneous vasculitis, Pityriasis
rosea (PR), Discoid lupus erythematosus, Guttate psoriasis, Sarcoidosis,
Raynaud’s phenomenon, non-specific lesions resembling genital warts,
Beau’s line and one severe case of purpura fulminans with a promising
outcome. Moreover, we presented 6 vaccine-induced cases comprising LP,
Urticarial vasculitis, PR, Parapsoriasis, and Localized Morphea. The
diagnosis of all cases has been proven by histopathological evaluation.
We included pertaining anamnesis details of each patient together with
vivid classifying images to pinpoint the morphologic features of each
condition. In line with our previous studies, the vaccine-induced
eruptions were less severe compared to infection-related complications
of COVID-19 and are mostly controllable by antihistamines and
corticosteroids administration. Therefore, reporting such events should
not hinder COVID-19 vaccination in the general population.
Highly exothermic process characteristics of catalytic reactors with integral heat exchange structures
Authors: Chen Junjie 
Published: February 2023

In modern industrial practice, a variety of highly exothermic reactions
are promoted by contacting of the reaction mixture in the gaseous or
vapor phase with a heterogeneous catalyst. A need exists for improved
catalytic structures employing integral heat exchange which will
substantially widen the window or range of operating conditions under
which such catalytic structures can be employed in highly exothermic
processes like catalytic combustion or partial combustion. The highly
exothermic process characteristics of catalytic reactors are
investigated with integral heat exchange structures. Ethane mole
fraction and gas-phase reaction rate profiles in catalytic reactors are
presented, and ethane mole fraction, flow velocity, gas-phase reaction
rate, and temperature contour plots are illustrated for catalytically
supported thermal combustion systems. The present study aims to provide
an improved reaction system and process for combustion of a fuel wherein
catalytic combustion using a catalyst structure employing integral heat
exchange affords a partially-combusted, gaseous product which is passed
to a homogeneous combustion zone where complete combustion is promoted
by means of a flame holder. Particular emphasis is placed upon the
catalytic reactor configuration that allows the oxidation catalyst to be
backside cooled by any fluid passing through the cooling conduits. The
results indicate that the percentage of reaction completed in the
exothermic catalytic reaction channel depends both upon the flow rate of
the fuel-oxidant mixture through the exothermic catalytic reaction
channel and upon the physical characteristics of the catalytic reactor.
The tortuosity of the catalytic channels is increased by changing their
cross-sectional area at a multiplicity of points along their
longitudinal axes. The gas flow velocity entering the exothermic
catalytic reaction channel should exceed the minimum required to prevent
flashback into the fuel-oxidant stream upstream of the reactor if the
fuel-oxidant mixture entering the exothermic catalytic reaction channel
is within the limits of flammability. Catalytically-supported thermal
combustion in the catalytic reactor is achieved by contacting at least a
portion of the carbonaceous fuel intimately admixed with air with a
solid oxidation catalyst having an operating temperature substantially
above the instantaneous auto-ignition temperature of the fuel-air
admixture. The film heat transfer coefficient provides useful means of
characterizing the different flow geometries provided by the various
flow channel configurations which distinguish the catalyst-coated
channels from the catalyst-free channels of the catalyst structure. The
total residence time in the combustion system should be sufficient to
provide essentially complete combustion of the fuel, but not so long as
to result in the formation of oxides of nitrogen.

OBJECTIVETo determine the mechanism of reduced pancreas size in type 1 diabetes and the significance of islet-derived insulin in pancreatic growth.RESEARCH DESIGN AND METHODSUsing a validated and standardized MRI protocol, we measured pancreas volume and shape in a family with an autosomal-dominant insulin gene mutation that results in insulin deficiency similar in severity to that of type 1 diabetes but without autoimmunity. DNA sequencing confirmed the mutation in all four affected individuals and none of the four control family members. Insulin secretory capacity was determined by measuring postprandial urinary C-peptide.RESULTSFamily members with this form of monogenic diabetes had a markedly smaller pancreas and a severely impaired postprandial C-peptide level than family members without diabetes.CONCLUSIONSThese results suggest that severe insulin deficiency, rather than islet-directed autoimmunity, leads to reduced pancreas size in type 1 diabetes and that insulin is a major trophic factor for the exocrine pancreas.
Three-dimensional annular heat source for the thermal simulation of coaxial laser metal deposition with wire
Authors: Zapata Avelino , Zhao Xiao Fan , Li Shiyu , Bernauer Christian , Zaeh Michael F. 
Published: February 2023

Coaxial laser metal deposition with wire (LMD-w) is an innovative additive manufacturing technology in which a wire is coaxially fed through the center of a hollow laser beam into a laser-induced melt pool. This special configuration results in a direction-independent process, which facilitates the manufacturing of thin-walled metal components at high deposition rates. However, laborious experimental test series must be conducted to adjust the process parameters so that the substrate and the part do not overheat. Therefore, models are needed to predict the resulting temperature field and melt pool dimensions efficiently. This paper proposes a finite element simulation model using an innovative heat source, which considers the unique intensity distribution of the annular laser spot. The heat source parameters were calibrated experimentally based on fusion lines obtained from metallographic cross sections of aluminum alloy samples (AA5087 wire and AA6082 substrate). Subsequently, the temperature distribution in the substrate plate was measured by means of thermocouples to validate the developed model. It was shown that the proposed heat source replicates the heat input accurately. With the presented model, essential features for process development, such as the temperature field and the melt pool dimensions, can be reliably predicted. The model contributes to a better understanding of the LMD-w process and facilitates an efficient process development in future research work as well as for industrial applications.

Published: February 2023

AbstractThere have been significant efforts to transform traditional farming into organic farming practices. It is believed that this transformation would guarantee the long term production while it also maintains the environment. Studying the differences between these two practices in the form of maps can be useful for understanding spatially how effective the transformation has been achieved. This is because soil varies in space. The main aim of this research is to study the spatial variability of Total Nitrogen, pH and Organic Carbon in the soil. Methods used in this study consists of : (a) data capture; (b) data input in GIS; (c) processing data using Kriging: (d) analysis and presentation of results. The results showed that : (a)Soil organic content in the study area was generally low suggesting the future warning; (b) Using pH, Organic Carbon and Total N as indicators of assessing the differences between organic and inorganic practices, indicating that there has not been significant different between these practices; (c)The analysis of spatial variability using Kriging in GIS environment could uncover the spatial variability and suggested the way of managing the study area.

Purpose: Hospitalization in Indonesia continued to increase by 5.2% per year in 2018, with the most significant number of hospitals in Indonesia being in the province of East Java. However, Indonesia is the most important contributor to overseas medical visits. Total expenses reach IDR 161 trillion/year (US$ 11.5 billion/year), and 80% of visits are to Malaysia, where every year, million Indonesian citizens (WNI) seek treatment abroad. Of this amount, the total costs incurred reached IDR 97 trillion. This becomes a question, what triggers Indonesian citizens to seek treatment abroad? This study aims to analyze the factors that influence business performance in hospitals in East Java.
Methods: This study used a purposive sampling technique with a total sample of 62 respondents. Respondents in this study were hospital leaders in East Java. This study uses a quantitative approach with the analysis in this study using Smart PLS.
Result: the results show that environmental uncertainties hurt the business performance of the hospital. This result is due to environmental uncertainties being a broad factor, difficult to predict either individually or collectively. However, environmental uncertainties have a significant positive effect on strategic orientation. Environmental uncertainties have a negative and significant effect on managerial capability. Meanwhile, strategic direction and managerial capability have a positive and significant effect on the business performance of hospitals in East Java.
