A sequence of strictly positive integers is said to be primitive if none of its terms divides the others. In this paper, we give a new proof of a result, conjectured by P. Erdős and Z. Zhang in 1993, on a primitive sequence whose the number of the prime factors of the termes counted with multiplicity is at most 4. The objective of this proof is to improve the complexity, which helps to prove this conjecture.

Published: May 2021

The postpartum period is a transitional period experienced by married couples who require adjustments to the presence of changes in their relationship, especially when the wife is experiencing postpartum stress (depression) during that period. The postpartum period causes changes in conditions followed by changing roles and responsibilities, which can affect the communication relationship between partners. This study focuses on communication patterns of married couples in postpartum pressure using the Interpersonal Communication Patterns Theory approach which is supported by the theory of relationship turbulence. The research method used is a qualitative method with data collection techniques in the form of interviews with four husband and wife couples who live in the city of Bandar Lampung, the determination of the informants is obtained through a snowball sampling strategy (multistage method) with expert informants as data confirmation. The results show that all couples have a separate balanced communication pattern (balanced split pattern) during the face of postpartum stress, which is marked by the division of responsibilities in different roles. In a balanced split communication pattern, all informants experience interferences as well as communication supports, and some experience relationship uncertainty, while constructive strategies are used as approaches in conflict management strategies between partners, characterized by open communication and negotiation. Conflicts related to childcare tasks and lack of quality interactions were the findings of this study.

Authors: Kushartomo Widodo , Wiyanto Henny , Christianto Daniel
Published: May 2021

This research aims to make ultra high strength Reactive Powder Concrete (RPC) with marble powder as one of the components. The use of marble powder can increase Calcium Silicate Hydrate (CSH) and the strength of RPC. The research method used to achieve the objectives is experimental and divided into two steps. The first step is the characterization of a marble and micro silica powder mixture. Stoichiometry calculations are performed to determine the composition of the mixture. The test sample is made in the form of pellets consisting of a mixture of marble powder, micro silica, and water. The water content used is at 30% - 50%. Maintenance is carried out by immersion in water with the temperature of 20oC for 27 days and in steam at temperatures 200oC, 250oC, and 300oC with 2 atm pressure for 4 hours. Material characterization is carried out using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The second step in this research is the RPC compressive strength test. The test sample is made in the form of a cube measuring 50 x 50 x 50 mm. This cube is a mixture of water, cement, micro silica, marble powder, sand, and superplasticizer. Material composition is arranged based on the characterization of the sample pellet test, and maintenance of the sample cube test is carried out as in the sample pellet test.

Published: May 2021

Simulations were carried out to visualize the ratio of granular attachment to porous surfaces. This simulation uses a uFlex three-dimensional simulation using three sizes of porous surface systems in the condition of the smallest human pores and the most extensive human pores and the condition of wet skin and dry skin. Each system was tested using five granular particle sizes according to the range of the makeup granules’ size to determine the optimal adhesive. The results show that the number of cosmetic granular particles entering the porous surface system is directly proportional to the porous surface volume and moisture and inversely proportional to the granular cosmetic size. The larger the cosmetic granular used, the less granular enters the pore.
Sale of agricultural lands located outside built-up area in Romania: novelty elements introduced by Law no. 175/2020
Authors: Veress Emőd
Published: May 2021

Law no. 17/2014 on some measures to regulate the sale of agricultural land located outside the built-up area was adopted among other reasons to ensure food security and protect national interests in the exploitation of natural resources. These goals are perfectly justified and foreshadow changes in the global environment that will affect social and economic arrangements in the future with great impact. In this context, the importance of protecting agricultural land as a natural resource of central importance is a legitimate political goal. However, the methods used must be very carefully chosen in order to create a legal regime for the sale of agricultural land that respects, on the one hand, the requirements of European law and, on the other hand, fulfills the national interest as far as possible. The current legal regime, created by amending Law no. 17/2014 by Law no. 175/2020 for the amendment and completion of Law no. 17/2014, in force since 13 October 2020, creates a legal regime that raises more questions than it settles regarding the real challenges outlined above.

Prerequisites of feminist discourse formation in Russian sociology of the XIX c.: M. I. Mikhailov .
Authors: Baturenko Sergey
Published: May 2021

The article considers the ideas of the Russian writer, poet and journalist M. I. Mikhailov, that became intellectual prerequisites for the formation of feminist discourse in Russian sociology of the XIX century. Domestic thinkers have contributed greatly to the emergence in Russia of feminism as a social phenomenon and the theory of feminism in the history of Russian social thought. The specifics of historical and cultural development have influenced the reflection of many issues within the social sciences, including the need to explore the “female issue” in sociology. The author shows that the problem of the position of women in society is markedly expressed in the context of Russian culture and is widely revealed in Russian literature in the works of famous writers, poets, journalists, philosophers, in particular in the works of M. Mikhailov. This article can be considered as an attempt to develop and deepen courses on the history of Russian sociology, it gives an idea of how feminist discourse was formed in classical sociology. The presentation of the problem of inequality, overcoming the dependent position of women and ensuring their rights in Russia differs from the Western specificity. This difference is reflected in the works of M. Mikhailov. The author shows significant influence on shaping the feminist discourse of European scholars, on the one hand. On the other hand, the author describes a revision and critical analysis of these ideas in the works of the Russian writer. The article analyzed Mikhailov’s creativity as one of the components of the process of spiritual and intellectual development of Russian social thought, immediately preceding the emergence of sociology in Russia and the formation of feminist discourse within some leading scientific schools.

Motherhood in the Karelian village: traditional practices in the context of Russia-wide changes (late XIX — early XX c.)
Authors: Litvin Julia
Published: May 2021

Traditions of Karelian maternity rituals are widely represented in the ethnographic historical science literature. At the same time motherhood as an institution and as a social and cultural status deserves special consideration. The paper is aimed at describing the development of the motherhood within Karelia in historical dynamics, as well representing the social and cultural status of the mother and the changes in the strategy of reproductive behavior in the Karelian village. The events presented in the paper refer to the period of the late XIX — early XX c. It was a time of economic, social and cultural reforms in Russian society, which had some specific repercussions on the empire borderlands. The paper uses a large number of recently published and unpublished ethnographic and historical sources, dialect vocabulary data, some of the author’s field materials and scientific works on the topic. The author adheres to the principles of gender history proposed by J. Scott, which involves the analysis of cultural symbols, normative prescriptions and social institutions and life stories of individual women. The author comes to the following conclusions. 1. Marriage and the maternity increased the social prestige of the peasant women, because they realized her main purpose. 2. The gender of the child had a different meaning for the male and female part of the peasant family collectives. If considering the patrilocal line of inheritance, preference was given to the birth of a boy. At the same time, the Karelian language data indicate a higher status of the mother after the birth of the girl. 3. There was a change in reproductive behavior in the North Karelian families in the second half of the XIX c. towards to reducing the number of children in the family to two or five. The reasons for such transformation were the growth in the importance of non-agricultural earnings, and the border position of the region (the cross-border marriages), which changed the customary cultural norms. 4. Some elements of modernization were not perceived by Karelian women. They continued to apply to rural midwives despite the growth of the network of obstetric care, and they also preferred the bathhouse or barn as a place for childbirth instead of medical institutions.

Published: May 2021

The role of institutional instruments in the regulation of the monetary sphere has been substantiated. It shows the narrowness of the monetary approach to implement macroeconomic policy, the concentration of central banks' activities on financial intermediaries and the rejection of gоals of the economic development. The basics principles of using institutional instruments in monetary regulation are as follows: creating conditions for ensuring the national economy development at low inflation rates; implementation of effective lending to the real sector by central bank; ensuring the coordination of the interests of the state, the central bank and the main social macro-groups in the monetary sphere.
TRANSFORMATION OF BUSINESS MODELS IN LIGHT INDUSTRY IN THE CONTEXT OF ROBOTIZATION
Authors: Serhiyevich T.
Published: May 2021

The article is devoted to the study of the specifics and transformation of business models in modern light industry in the context of robotization. It was revealed that the subjects of the light industry and the fashion industry are focused on the production of social relations, including the formation of needs and mechanisms for the recognition and social reproduction of the sign system, the construction of the connection of manufactured goods with the generally accepted sign system, management of the mechanisms of access of various groups of the population to sign goods. Against the background of the spread of the business model of fast fashion, the development of which was facilitated by social (the formation of a consumer society), economic (economic growth in the second half of the 20th century and the growth of welfare) and technological (robotization, the development of transport and information and communication technologies) factors, new business models are formed according to the principles of responsible consumption. It has been proven that in the short and medium term, their widespread and growth are unlikely, and the recycling strategies of fabric and clothing manufacturers will remain peripheral. As a result, it was found that even in radically different business models, the production of social relations is fundamental, and capitalization is carried out through the conversion of cultural, symbolic and reputation capital into economic capital.
Gender Disparity in Risk Factors of COVID-19 Mortality Rate
Authors: Ranjan Uma , Kini Anush , B Harish P , Anand Monica
Published: May 2021

Incidence and mortality rates due to COVID-19 have varied widely in different parts of the world and placed a huge strain on hospital resources. Understanding the underlying reasons behind such variation is crucial to developing population-specific or even individual-specific management strategies. This paper presents a comprehensive analysis of incidence and mortality rates from data collected over a cumulative period of approximately 6.5 months from February to August 2020 across 411 districts of India, totalling over 2 million individuals. We identify the health factors which have both positive as well as negative correlates with high mortality rates, using data obtained from district-wise aggregated COVID-19 incidence and mortality rates and health data obtained from National Family Health Survey (NFHS). To obtain robust indicators, we apply both machine learning techniques as well as classical statistical methods and show that the same factors are identified by both methods. We also identify positive and negative correlates at multiple population scales by dividing the cohort into sub-cohorts formed from two Indian states which were further segregated by gender. We show that there is a disparity of risk factors among males and females. While obesity is the highest risk factor for men, anaemia is the highest risk factor for women. Hence, to better manage the health of a specific group of people, it is important to consider gender-wise heterogeneity in health risk factors which could contribute to differing vulnerabilities

Published: May 2021

Objective To determine the role of diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) imaging to guide stereotactic biopsy for the diagnosis of intracranial angiitis. Case presentation In a 28-year-old woman who had experienced inactive headache and right limbs numbness for 4 days, preoperative magnetic resonance (MR) scanning, enhanced scanning, diffusion tensor imaging, magnetic resonance spectroscopy, diffusion-weighted imaging (DWI), and ADC image scanning were performed. Stereotactic biopsy was performed in one target where the area of edema detected with MR FLAIR, and two targets where the area shown as a high-value and a lower-value area in the DWI/ ADC image. Pathological examinations together with computed tomographic and enhanced MRI scans were conducted after surgery. A preoperative enhanced MRI scan showed a uniform low-intensity lesion in the patient’s left centrum semiovale, with a volume of 3.1 cm3. The DWI and ADC images showed uneven high-intensity signals and different ADC values in the lesion area, respectively. During surgery, tissues around the lesion and the lesion center were sampled at the three selected targets. The postoperative pathological diagnosis was primary angiitis of the central nervous system, and the patient was given anti-inflammatory medication and hormone therapy. The 3-year follow-up confirmed that the patient had recovered well, with a Glasgow Outcome Scale score of 5.Conclusion DW-MRI and ADC images can be reliably used to determine the location of small intracranial lesions, and guide stereotactic biopsy to facilitate the diagnosis of primary vasculitis of the central nervous system.

Authors: Upadhyay Anurag , Singh Shivam , Sharma Divya , Taya Sofyan A
Published: May 2021

This manuscript deals with a novel photonic crystal fiber (PCF) in which PCF's cladding region bears the air holes of square shape organized in a circular manner. The fiber core is perforated with four circular air-filled holes to instate high nonlinearity and large negative dispersion. The numerical analysis of the designed model is supported by the finite element method (FEM) based COMSOL Multiphysics tool. The optical properties of the propounded PCF like nonlinearity, dispersion, effective area and propagation loss have been observed by altering its geometrical dimensions, especially the diameter of four air holes introduced in the fiber core. Simulation outcome verifies a very high nonlinear coefficient value of 300 W− 1 Km− 1 which is the highest ever achieved value without using any nonlinear materials or liquids in the author's best knowledge. In parallel, the chromatic dispersion is also found negative and reached to the maximum value of -1689 ps/nm/km. Besides, the other essential optical parameters such as birefringence, numerical aperture, and propagation loss were also measured as 2.40×10− 3, 0.59, and 4.12×10− 11 dB/m along with an extremely high core power fraction of 99.98%. Hence, the propounded PCF is suitable for residual dispersion compensation, supercontinuum generation, solitons generation, polarization sustaining devices as well for high bitrate transmission.

Authors: Jesus Géssica K , Jugend Daniel , Paes Luis Alberto B , Siqueira Regiane M , Leandrin Matheus A
Published: May 2021

Brazil plays a prominent role in the global production of sugarcane and contributes to the renewable energy sector by producing ethanol. However, few studies have explored the adoption of the circular economy in the sugarcane ethanol sector. This article is aimed at analyzing and prioritizing barriers to the adoption of the circular economy in leading Brazilian sugarcane ethanol companies. For this, the analytical hierarchy process method and case studies methods were used. The main barriers identified were economic and financial, mainly due to dependence on high investments in production process technologies and the resulting uncertainties about returns. Another barrier was the lack of Brazilian legislation concerning the circular economy. We discuss the implications of our findings and present mechanisms for overcoming barriers and the role in supporting circular economy adoption in emerging economies.

Published: May 2021

Purpose

To evaluate the changes in anterior chamber dimensions including horizontal anterior chamber diameter (HACD), anterior chamber depth (ACD), and iridocorneal angle (ICA) following small incision lenticule extraction (SMILE) using Scheimpflug-Placido disk tomographer (Sirius).
Methods

The records of the 73 eyes of 47 patients who received SMILE for myopia and myopic astigmatism were retrospectively reviewed. Preoperative and 6-month postoperative measurements of central corneal thickness (CCT), HACD, ACD, ICA, nasal anterior chamber angle (nACA), and temporal anterior chamber angle (tACA) were obtained by tomography, and compared with paired t-tests. Pearson’s correlation and linear regression tests were used to evaluate the relationship between these parameters.
Results

The CCT, HACD, and ACD values decreased significantly at 6-month postoperatively (p < 0.05 for all). ICA, nACA, and tACA showed no statistically significant difference postoperatively (p = 0.54, p = 0.118, and p = 0.255, respectively). Pearson’s correlation analysis confirms negative relationship between Δ-HACD and Δ-tACA (r=-0.475, p < 0.01), and a loose negative relationship between change in ACD and change in ICA (r=-0.282, p = 0.016). Age and Δ-tACA were found as predictive parameters for Δ-HACD and, Δ-ICA was a predictor for Δ-ACD.
Conclusion

While HACD and ACD decreased significantly, there was no significant change in ICA, nACA and tACA. Changes in HACD and ACD should be considered in terms of subsequent surgeries after SMILE.

PURPOSE Currently, limited evidence-based guidelines exist for the effective management of chemotherapy induced dysgeusia in cancer outpatients. In this pilot study, we used innovative insights from gastrological sciences such as selective taste management to improve the taste of bread for cancer outpatients. We investigated whether it is feasible for cancer outpatients and family caregivers to bake personalized bread themselves at home, whether such bread is considered tasty and if daily consumption of it has any effect on anthropometric measurements. METHODS Included patients (N=112) are randomly divided in a bread-baking group (BBG) (N=54) and a control group (N=58). Their individual taste thresholds profile is assessed using the innovative O-Box. Anthropometrics and structured questionnaires are used to compare the effects of personalized bread after one month follow-up. RESULTS Only 17% of the BBG required some telephone or online assistance to correctly apply the prescribed recipe. In 60% of the cases, the bread was prepared by the family caregiver. Compliance was high and no side effects were observed. Over 80% of the BBG perceived personalized bread as equally or more tasteful despite their stressful taste alterations. Compared to the control group loss of bodyweight and Body Mass Index in the BBG was not significant (p .968 and p .956 respectively). CONCLUSIONS Baking personalized bread at home appeared to be feasible. Selective taste management based on individual taste thresholds profiles should be studied more in depth using whole meals in a larger cancer outpatients population.

Authors: Azeez Musa O , Tanimu Abdulkadir , Alhooshani Khalid , Ganiyu Saheed A.
Published: May 2021

This study reports the synthesis of mesoporous metal-modified nitrogen doped activated carbon (AC-N-Mo) from date seeds by ZnCl2 activation and its applicability for selective adsorptive desulfurization of dibenzothiophene (DBT). The AC-N-Mo exhibits higher adsorption capacity for DBT at 100 mg-S/L with the maximum value of 99.7% corresponding to 19.94 mg-S/g at room temperature than the unmodified carbon with 17.96 mg-S/g despite its highest surface area and pore volume of 1027 m2g− 1 and 0.55 cm3g− 1 respectively. The adsorption capacity breakthrough follows the order AC-N-Mo > AC-Mo > AC > AC-N. AC-N-Mo also displayed excellent selectivity in the presence of aromatics (toluene, naphthalene and 1-methylisoquinoline). The enhancement in the DBT uptake capacities of AC-N-Mo is attributed to synergy effect of nitrogen heteroatom that aid well dispersion of molybdenum nanoparticles on carbon surface thereby improving its surface chemistry and promising textural characteristics. The kinetic studies showed that the DBT adsorption proceeds via pseudo-second order kinetics while the isotherm revealed that both Freundlich and Langmuir fit the data but Freundlich fit the data more accurately for the best performing adsorbent. The physico-chemical properties (surface area, pore volume, carbon content, particle size etc.) of as-prepared adsorbents namely; AC, AC-N, AC-N-Mo and AC-Mo were characterized by N2- physisorption, X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Spectroscopy/Energy Dispersive Spectroscopy (SEM/EDS), Raman Spectroscopy (RS), Fourier Transform Infrared Spectroscopy (FTIR) and Ammonia-Temperature-Programmed Desorption (NH3-TPD).
A comparison of laparoscopy versus laparotomy for the management of adnexal masses during pregnancy over the last 16 years: retrospective study
Authors: Zhang Zhiqiang , Mu Boran , Leng Jinhua , Li Menghui
Published: May 2021

Background

Adnexal masses during pregnancy is not rare. More and more evidences imply that operative laparoscopy for adnexal masses performed during pregnancy could be safe and feasible. We procured and evaluated the surgical, obstetric outcomes between laparoscopy and laparotomy for the management of adnexal masses during first and second trimester period in our hospital.
Results

117 pregnant women with adnexal masses were treated by laparoscopy (69 cases) or laparotomy (48 cases) between July 2003 and March 2019. The laparoscopy group had a significantly lower blood loss (22.0 ± 3.4ml vs 41.7 ± 4.3ml, P = 0.0004), a shorter onset of flatus after operation (24.2 ± 0.1h vs 41.6 ± 1.9h, P < 0.0001) and a shorter hospital stay (3.5 ± 0.2 days vs 6.6 ± 0.2 days, < 0.0001) than the laparotomy group. No patient from either group required a blood transfusion. There is no significant difference in obstetric outcomes, including preterm labor and fetal loss. The median follow-up time was 3.5 years (range, 1.5–11.5 years) after surgery. The median age of the children was 2.5 years (range, 1-9.5 years). No notable abnormality was found.
Conclusions

In this retrospective study, compared with laparotomy, laparoscopy has successful outcome with lower blood loss, shorter onset of flatus after surgery, and shorter hospital stay, all of those suggest that operative laparoscopy could be promising for adnexal masses performed during pregnancy.

Authors: Colbran Richard , Ramsden Robyn , Pepin Genevieve , Toumbourou John , Stagnitti Karen
Published: May 2021

Background

Organisational performance measurement (OPM) is an evidence-based tool for planning business improvement and creating sustainable competitive advantage. Despite its value, non-acute health charities under-utilise OPM. The purpose of this paper is to provide the rationale and a detailed description of an OPM implementation model developed specifically for non-acute health charities. The aim of this new model is to encourage uptake of OPM in this sector.
Methods

The authors investigated the understanding and use of OPM in the non-acute health charity sector through a large mixed methods study. Multiple research activities, including PRISMA systematic reviews and two case study evaluations, identified factors and activities that are important for successful implementation of OPM in non-acute health charities. These were then integrated to form an implementation model.
Results

The resultant implementation model is a methodological tool designed to account for, and respond to, the specificities and strategic management needs of the non-acute health charity sector. It integrates five distinct yet interconnecting components – a theoretical framework; guiding principles; an implementation framework; measurement domains; and a monitoring and improvement tool.
Conclusions

The innovative OPM implementation model was designed as an evidence-informed approach to support the implementation of OPM in the non-acute health charity sector. It is titled the Non-Acute Health Charities Measurement Advantage Implementation Model (MAIM). Future studies should test the model in different organisational contexts and the impact of OPM on non-acute health charity performance.

Air pollution exposure has been associated with a multitude of diseases and poses a significant concern to public health. For targeted environmental risk communication and interventions to be effective, it is important to correctly identify characteristics associated with worry of harm from air pollution. Using responses from 3,630 participants of the Health Information National Trends Survey 4 Cycle 2, we assessed worry of harm from exposure to indoor (IAP) and outdoor (OAP) air pollution separately. Multinomial logistic regression models were used to calculate odds ratios and 95% confidence intervals. Hispanics were more likely to worry about harm from IAP and OAP compared to non-Hispanic whites. Participants who lived in urban counties were more likely to worry about harm from IAP and OAP compared to those who lived in rural counties. Finally, those who believed their chance of getting cancer was high were more likely to worry about harm from IAP and OAP compared to those who thought their likelihood of getting cancer was low. Worry of harm from IAP and OAP varied across sociodemographic and cancer-related characteristics. Public health professionals should consider these characteristics when developing targeted environmental risk communication and interventions.

Background Technostress during the COVID-19 pandemic has become more prevalent as a result of the global preventive measures applied to limit the spread of infection. These measures included remote working from home in both public and private organizations.ObjectivesTo study Technostress and challenges of remote Virtual work environment among University Staff Members at Menoufia University, Egypt.MethodsA cross-sectional study was conducted over Menoufia university academic staff members in Egypt. The participants were chosen from both practical and theoretical colleges in Menoufia University using a multistage random sample. Tarfadar techno-stress questionnaire was used. Cortisol blood level was measured for all participants.Results: This study included 142 participants. The mean age of the group was 36.32± 6.41 years. 52.1 percent worked in practical colleges, and 60.6 percent were lecturers or higher. Their mean cortisol level was 15.61± 7.07mcg/dl. Participants who were females, reside in rural areas, held a lecturer or higher position, had poor work-environment Wifi, and lacked technical training had significantly higher levels of technostress subscales. Most of the technostress subscales were significantly correlated with age and blood cortisol levels. The predictors of work overload in multivariate regression were female gender and a work environment with poor WIFI. Female gender, theoretical colleges, being lecturer or higher and poor WIFI were the predictors for invasion. ConclusionAmong university staff members, Technostress was found to be evident. High levels of technostress were significantly influenced by age, higher professions, female gender, and a bad workplace environment.

Development of biofuels to replace fossil fuels by bioenergy systems has been attracting attention as an environmental-friendly process. Dealing with biowaste by anaerobic digestion not only disposes of wastes but also producing biogas during the treatment processes for providing the renewable energy source at low-cost while conserving fossil fuel. This study aims to use life cycle assessment and cost-benefit analysis tools in evaluating and comparing the potential environmental impacts and cost benefits for the swine farm operation with and without a rapid-build anaerobic fermentor module installed into the original three-stage wastewater treatment system, which module helps biogas production as energy recovery in swine farms. The results indicate that the module could help reduce carbon footprint by 22.6%, methane by 51.8%, sulfur oxides by 92.6%, nitrogen oxides by 74.2%, carbon monoxide by 54.7%, nitrous oxide by 28.6%, suspended particulate by 95.4%, and non-methane volatile organic compounds by 80%. Using this module made the reductions of damage impacts were human health 82%, ecosystem quality 59%, and resource scarcity 87%. The daily average biogas production was 46.38 m3 and its annual electricity generation income was 6,091 USD. This study allows identifying the lowest environmental impact to support the adoption of sustainable waste treatment and the opportunity for converting waste to be energy and utilization with economic benefits for small-scale swine farms.

Purpose Antineoplastic treatments, mainly chemotherapy, affect the kidneys, causing toxicity, and can trigger acute and long-term chronic kidney injury. The objective of this study was to analyze the prevalence of renal disorders in patients with oncohematological neoplasms under antineoplastic treatment. Methods This is a retrospective cohort study involving 75 patients affected by hematological cancer who underwent chemotherapy between 2012 and 2108 in the Hematology Sector of the Walter Cantídeo University Hospital of the Federal University of Ceará. Sociodemographic and clinical data, blood biochemical assessment, and Glomerular Filtration Rate (GFR) were analyzed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. The data were tabulated, transferred to the Statistical Package for the Social Sciences software, version 20.0, and analyzed using Fisher's exact test or Pearson's chi-square test, followed by the Mann-Whitney test. Additionally, the variables were treated using a multinomial logistic regression model (p <0.05). Results The prevalence of renal disorders was 52.4%, considering the episodes of GFR through the CKD-EPI equation. There was an association between the reduction in GFR and the variables: female gender (p = 0.002), diagnosis of multiple myeloma (p = 0.008), start of treatment within 40 days (p = 0.005), protocol Cyclophosphamide, Oncovin, Prednisone (p = 0.026), Idarubicin (p = 0.032), Vidaza protocol, Dexamethasone, Cyclophosphamide (p <0.001), Zoledronate (p <0.001) and Pamidronate (p = 0.012). It was also observed that the Cancer and Leukemia Group B protocol (p <0.001) is inversely associated with a reduction in GFR. Conclusions The prevalence of renal disorders is high in the service evaluated, requiring periodic monitoring of the evaluation of renal function, since the reduction in GFR is statistically associated with different protocols used.
Theoretical Band and Confinement Interpretation of 1D Electrons: Impact on Plasmons and Exchange-Correlation Functionals
Authors: Sharma Akariti
Published: May 2021

Theoretical band and confinement interpretation of electron gas in lowest energy sub-band of quasi- 1D metallic wire have been done. Counter effects have been investigated on electrostatic oscillations (plasmons) determined by the electron density response function. Carrier correlations are treated by incorporating the local exchange-correlation (XC) effects within mean- field approximation. Results obtained are in quantitative agreement with experiments data of Nagao et al. (2006 Phys. Rev. Lett. 97 116802). Variation in both degeneracy and confinement potential cause a clear energy- shift in the electrostatic oscillations accomplished by asymmetry in band effective mass. Resultant massasymmetry is attributed to the greater strength of XC- effects. These contributions turns out to be quite logical in describing the splitting of 1D-bands over ad-hoc spin-orbital splitting idea of Nagao et al. Calculated XC-functionals agreed well with the lattice regularized diffusion Monte Carlo (LRDMC) simulation data (2006 Phys. Rev. B 74, 245427, 2009 J. Phys. A:Math.Theor.42 214021). Competition among XC-functionals and kinetic energy tendencies decides a criterion by satisfying which a metallic quasi-1D wire may undergo an instability at certain critical temperature (Tc).
Collider bias in administrative workers’ compensation claims data: A challenge for cross-jurisdictional research
Authors: Lane Tyler J
Published: May 2021

Purpose Workers’ compensation claims consist of occupational injuries severe enough to meet a compensability threshold. Theoretically, systems with higher thresholds should have fewer claims but greater average severity. For research that relies on claims data, particularly cross-jurisdictional comparisons of compensation systems, this results in collider bias that can lead to spurious associations and confound analyses. In this study, I use real and simulated claims data to demonstrate collider bias and problems with methods used to account for it. Methods Using Australian claims data, I used a linear regression to test the association between claim rate and mean disability durations across Statistical Areas. Analyses were repeated with nesting by state/territory to account for variations in compensability thresholds across compensation systems. Both analyses are repeated on left-censored data. Simulated claims data are analysed with Cox survival analyses to illustrate how left-censoring can reverse effects.Results The claim rate within a Statistical Area was inversely associated with disability duration. However, this reversed when Statistical Areas were nested by state/territory. Left-censoring resulted in an attenuation of the unnested association to non-significance, while the nested association remained significantly positive. Cox regressions on simulated data showed left-censoring can also reverse effects. Conclusions Collider bias can seriously confound work disability research, particularly cross-jurisdictional comparisons. Work disability researchers must grapple with this challenge by using appropriate study designs and analytical approaches, and considering how collider bias affects interpretation of results.
