The Predictive Power of Sleep Quality by Morning-Evening Chronotypes, Job Satisfaction, and Shift Schedule in Nurses: A Cross-Sectional Study

Background: Among nurses, sleep quality is an important factor which can be associated with many other factors, including job satisfaction, Morning-Evening (ME) chronotypes, and shift schedule. Besides, poor sleep quality can cause some problems for nurses and negatively affect the quality of nursing care. Therefore, the present study aimed to determine the predictive power of sleep quality by ME chronotypes, job satisfaction, and shift schedule in nurses working in Urmia teaching hospitals in 2019. Materials and Methods: A total of 327 nurses working in teaching hospitals affiliated to Urmia University of Medical Sciences were recruited using stratified sampling. Data were collected using the demographic questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Minnesota Satisfaction Questionnaire (MSQ), and the Composite Scale of Morningness (CSM). Data were analyzed using linear regression analysis and Pearson correlation coefficient. Results: The results of the Pearson correlation coefficient and linear regression analysis showed that the ME chronotypes (R2 = 0.51, p = 0.006), job satisfaction (R2 = 0.51, p = 0.001), and shift schedule (R2 = 0.51, p = 0.005) are significantly correlated with the sleep quality among nurses. Conclusions: We concluded that the sleep quality was correlated with ME chronotypes, job satisfaction, and shift schedule, so that increased job satisfaction was associated with improved sleep quality, and the shift to the morning chronotype was associated with decreased sleep quality. Rotating shifts were also associated with higher sleep quality.
Entodermoscopy Update: A Contemporary Review on Dermoscopy of Cutaneous Infections and Infestations

In this up-to date review, literature concerning the various dermoscopic features of parasitic, viral, dermatophytic and bacterial cutaneous infections is composed. In addition artefacts as well as practical issues in dermoscopy usage are discussed; with the aim to empower dermatologists to promptly and non-invasively diagnose and manage cutaneous infections and infestations.
Clinico-Epidemiological Profile of Childhood Alopecia Areata Along with Dermoscopic Correlation: A Cross-Section, Observational Study

Background: Childhood alopecia areata (AA) is a common cause of dermatologic consultation; however, data is scarce in the present set-up. Objectives: To evaluate the clinico-epidemiological profile of childhood AA along with dermoscopic correlation. Methods: We conducted a cross-sectional study including 50 new cases of childhood AA for 1 year. Dermoscopy was performed in each child and findings recorded. Results: Childhood AA was more common in girls (M: F 1:1.4), mean age being 11.1 ± 3.7 years. Scalp was commonest site of involvement in 86% cases, while 32 (64%) children had mild disease (<25% involvement). Localized circumscribed patch was the commonest presentation in 37 (74%) children, while sisaipho was the least (2%). A positive family history of AA was noted in 5 (10%) children. Twenty-four children (48%) provided a history of atopic disorders, while 30% had a positive family history of atopy. Stress was the commonest precipitating factor in 13 (26%) subjects. Nail involvement was observed in 19 (38%) children (pitting >thinning), while systemic associations like vitiligo and thyroid dysfunction were present in 26% and 24% cases, respectively. Dermoscopy revealed yellow-dots to be the commonest finding in 44 (88%) cases, followed by short vellus hair and black dots in 76% and 28% children, respectively, while exclamation-mark hair was rare. Conclusion: Female gender, younger age, nail involvement, and presence of concomitant atopy, vitiligo, and thyroid dysfunction were associated with severe disease, but not statistically significant (p > 0.05). Regression model failed to detect any risk factors for severe AA. Dermoscopy is an important non-invasive tool for evaluating childhood AA.
Validation of Indian Diabetes Risk Score for Screening Prediabetes in West Tripura District of India

Background: Viswanathan Mohan and his team have developed “Indian Diabetes Risk Score” (IDRS) for identifying the Indians at risk for developing diabetes and prediabetes. Due to heterogeneity of Indian population, this risk score needs further validation in different parts across the country. Objectives: The objective is to estimate the sensitivity, specificity, positive, and negative predictive values of IDRS for screening prediabetes in West Tripura District. Methodology: It was a community-based cross-sectional study conducted in West Tripura district during January 1, 2018–December 31, 2019 among 325 self-declared nondiabetic individuals, selected by multistage sampling. Fasting blood sugar value was used as the gold standard to validate IDRS. Data were collected using a validated and pretested interview schedule. Data entry and analysis were performed in computer using SPSS-24. Receiver operating characteristic (ROC) curve was constructed to validate IDRS. Results: Among the study individuals, 19% and 6.5% were identified as prediabetic and diabetics, respectively. Optimum sensitivity of 83.13% and specificity of 82.64%, with positive and negative predictive values 62.16% and 93.45%, respectively, were observed at an IDRS score of ≥60 for identifying prediabetes and diabetes in this study population. IDRS showed good accuracy with an area under ROC curve of 0.832 (95% confidence interval: 0.77–0.88). Conclusion: IDRS is found to be a valid tool for screening prediabetes at community level in West Tripura district of India.
Perceived Risk in Women with High Risk Pregnancy: A Qualitative Study

Background: Risk perception in high-risk pregnancies influences the mothers' adherence to medical treatments and recommendations. Because of the lack of information about the women's perception of risk, the aim of this study was to explain perception of risk in high-risk pregnancies. Materials and Methods: This qualitative study was conducted on 25 women with a high-risk pregnancy in educational hospitals of Mashhad, Iran, from August 2017 to August 2018. Data were collected through semi-structured interviews and data saturation was reached after 29 interviews. Data collection and analysis were simultaneously carried out using the qualitative content analysis method adopted by Elo and Kyngäs in MAXQDA software. Results: Data analysis resulted in the four main categories of perception of risk control ability (risk controlling through experience, risk tolerance through relying on a higher power, and risk tolerance to reach family goals), wrong estimation of risk (wrong calculation of possible risks based on wrong beliefs and knowledge, and incorrect risk estimation caused by misunderstanding), possibility of mutual vulnerability of pregnancy and risk condition (possibility of vulnerability of the fetus to risk factors, and possibility of the mother's vulnerability to risk factors), and induced risk (risk induced by negative experiences, induced threat of unknown pregnancy outcome, and fear of ambiguous medical terms). Conclusions: The results of this study promoted our understanding of risk perception in women with high-risk pregnancies. Therefore, it will help to establish a-Ž better link between women with a high-risk pregnancy and the health team, enhance and improve maternal and fetal care.

Polymerization of methyl methacrylate with cobalt acetylacetonate-diethyl zinc catalyst system

Polymerization of methyl methacrylate was studied with a cobalt acetylacetonate-diethyl zinc catalyst initiator system in benzene medium at 40°C. When the stoichiometric ratio of Zn/Co is 2, the activity for polymerization is found to be maximum. The structure of the obtained polymethyl methacrylate is compared with that obtained using a free-radical initiator such as benzoyl peroxide. The structure of polymer and the Mw/Mn values indicate that cobalt acetylacetonate-zinc diethyl system has pronounced free-radical characteristics. A suitable mechanism is proposed from the kinetic studies. © 1995 John Wiley & Sons, Inc.

Background: Smartphone use is escalating among adolescents, thereby increasing the risk of its addiction among them. Objective: The objective of this study was to estimate the prevalence of smartphone use and its addiction among adolescents in 16–19 years of age group. Materials and Methods: An observational cross-sectional study was conducted among 496 students in the age group of 16–19 years. Relevant information was collected using a self-administered questionnaire and the Smartphone Addiction (SA) Scale. Chi-square test and logistic regression were applied to study the association between independent and dependent variables. Results: Smartphone use was found to be 83.9%. It was associated with age, area of residence, discipline, use of hands-free kit, and parents' education and income. The smartphone addiction rate was reported to be 37%. It was found to be associated with age, area of residence, place of education, duration of smartphone use, daily hours of use, perception that cellphone use is harmful to health, and parents' education and income. Conclusion: A high rate of SA among adolescents warrants effective strategies at local, state, and national level to address this growing health problem in this population.
A Strengths, Weaknesses, Opportunities, and Threats Analysis of Public Health in India in the Context of COVID-19 Pandemic

The coronavirus disease-2019 (COVID-19) was an unanticipated and unexpected public health emergency which turned into social, economic, and political emergency. India too was taken by sudden surprise. Nobody ever thought about the possibility of a complete lockdown of a country for more than 2–3 months. Patterns of change of COVID data available over lockdown periods indicate that the lockdown was effective in slowing the spread of the virus nationally but displays large state-level variations. [1] The lockdown was then followed by gradual step-wise unlocking. Public health in India underwent a lot of changes during this period. It will be interesting to see how the COVID-19 brought forth Strengths, Weaknesses, Opportunities, and Threats (SWOT) of public health in India. A SWOT analysis of China’s Prevention and Control strategy for the COVID-19 epidemic on a similar line was done during the early phase of pandemic. [2] A very brief SWOT analysis of public health in India is presented here with only three main highlights in each category. This is intended to be a constructive critical analysis of the current public health in India. This will also be helpful to chart the future course.
Back to the future in traumatic fracture shapes of lumbar spine: An analysis of risk of kyphosis after conservative treatment

Introduction: Nonosteoporotic burst vertebral fracture could commonly be treated with conservative or surgical approach. Currently, decision-making process is based on thoracolumbar (TL) AO spine severity injury score. However, some factors could affect posttraumatic kyphosis (PTK) and could be taken into account. The aim of the present study is to identify if axial and sagittal fracture shape and initial kyphosis are the risk factors for PTK. Materials and Methods: All consecutive patients treated between 2016 and 2017 for TL vertebral fracture with conservative treatment were retrospectively evaluated in the study. Only type A3 and A4 vertebral fractures were included in the study. Patients suffering from osteoporosis or other metabolic bone disease, aged above 60 years old were excluded from the study. Initial and 6 months X-ray from injury were analyze to evaluate local kyphosis and region of injury while initial assessment was performed with computed tomography to better identify fracture type and in some cases magnetic resonance imaging to exclude posterior ligament complex injury. Axial and sagittal view of the vertebral plate was analyzed and classified in three shapes according to fragment comminution and dislocation. Statistical analysis was performed trough STATA13 software. Student's t-test was used to evaluate the differences between initial and follow up kyphosis; odds ratio (OR) was used to evaluate the role of initial kyphosis, vertebral sagittal and axial fracture shape as a risk factor for PTK. Kruskal–Wallis test was used to assess the differences among vertebral shape fractures and final kyphosis. Fisher's exact test was used to assess the differences between fracture patterns and final kyphosis. Results: An initial kyphosis >10° ° (OR 36.75 P = 0.015), shape c vertebral plate (OR 147 P = 0.0015), and sagittal shape 3 (OR 32.25 P = 0.0025) are strongly related with PTK. Kruskal–Wallis test revealed a statistically significant difference among axial fracture shape (P < 0.0001) and sagittal fracture shape (P = 0.004) and also for initial kyphosis >10° (P < 0.0001). Fisher's exact test showed a significant difference for final kyphosis among pattern c3 and other patterns of fracture (P = 0.0001). Conclusions: A burst type lumbar vertebral fracture affecting a patient with initial local kyphosis >10° and comminution and displacement of vertebral plate and vertebral body is at high risk to develop a local kyphosis >20° in the follow-up if treated conservatively.
Expression of cyclin D1, p21, and estrogen receptor alpha in aflatoxin G1-induced disturbance in testicular tissue of albino mice

Background and purpose: Aflatoxin (AF) is a mycotoxin produced by various strains of the Aspergillus family. AFG1 as one of the most important types is highly found in cereals and grains. AF affects sperm production or even its quality. This study was designed to test the effects of AFG1 on mice testicular tissue. Experimental approach: Twenty-four Albino mice were divided into four groups of 6 each; a control group (0.2 mL corn oil and ethanol), three treatment groups with different periods (20 μg/kg AFG1 for 7, 15, and 35 consecutive days). All treatments were applied intraperitoneally. Biosynthesis of cyclin D1, p21, and estrogen receptor alpha (ERα) proteins was evaluated by immunohistochemistry (IHC) staining. Levels of cyclin D1, p21, and ERa mRNA were evaluated by the real-time polymerase chain reaction (RT-PCR) technique. Tubular differentiation index (TDI), reproductive index (RI), and spermiogenesis indices were also analyzed. Findings/Results: AFG1 increased the percentage of seminiferous tubules with negative TDI, RI, and SPI compared to the control group (P < 0.05). RT-PCR and IHC analyses illustrated time-dependent enhancement in p21 expression and cyclin D1 biosynthesis in AFG1-treated groups significantly (P < 0.05). While the protein and mRNA levels of ERa were significantly (P < 0.05) decreased in a time-dependent manner. Conclusion and implications: The chronic exposure to AFG1 reduced the expression and synthesis of ERa, increased the expression and synthesis of p21 and cyclin D1, impaired apoptosis, which in turn could impair spermatogenesis.
Exploring Facilitators of Regaining Autonomy in People with Spinal Cord Injury: A Qualitative Study

Background: One of the most important aims of rehabilitation in Spinal Cord Injuries (SCI) is regaining autonomy, which can affect individuals' Quality of Life (QOL). This study was conducted to understand the experiences of individuals with SCI in terms of regaining autonomy during transition from hospital to community. Materials and Methods: The present study was conducted using a qualitative research design. In this study, 15 semi-structured, in-depth interviews were conducted with individuals with SCI in Spinal Cord Injury (SCI) Association of Arak, Iran, from June 2018 to May 2019. The interviews were analyzed using the conventional content analysis method. Results: Data analysis emerged four core categories of “self-management” (adaptation to a new life, self-care, responsibility, and seeking information), “social support” (family and friends' support, health care providers' support, and peer support), “access to facilities and resources” (home modification, use of various rehabilitation techniques, and use of mobility equipment), and “spiritual and religious beliefs” (believing in divine destiny and performance of religious rites). Conclusions: The present study showed that several factors influenced the regaining of autonomy in individuals with SCI. It is important to consider the impact of these factors during transition from hospital to community. Health service providers can use the findings of this research to help these individuals regain their autonomy.
Effects of Fiber-surface Treatment on the Properties of Hybrid Composites Prepared from Oil Palm Empty Fruit Bunch Fibers, Glass Fibers, and Recycled Polypropylene

In this article, we report the effects of hybridization and fiber-surface modification on the properties of hybrid composites prepared from recycled polypropylene (RPP), coupling agents, oil palm empty fruit bunch (EFB), and glass fibers through a twin-screw extruder and an injection-molding machine. The surface of the EFB fibers was modified with different concentrations (10–15 wt %) and temperatures (60–90°C) of alkali solutions. The structure and morphology of the fibers were observed with the help of Fourier transform infrared spectroscopy and scanning electron microscopy. Different types of composites were fabricated with untreated, alkali-treated, and heat-alkali-treated fibers. Comparative analysis of the mechanical, structural, morphological, and thermal properties of the composites was carried out to reveal the effects of treatment and hybridization. The analysis results reveal that composites prepared from the alkali-treated (in the presence of heat) fibers show improved mechanical, thermal, and morphological properties with a remarkably reduced water absorption. Additionally, the crystallinity of RPP also increased with the development of biaxial crystals. The improvement of various properties in relation to the structures and morphologies of the composites is discussed
Studies of Lithium Intercalation into Carbons Using Nonaqueous Electrochemical Cells

Li/graphite and Li/petroleum coke cells using a in a 50:50 mixture of propylene carbonate (PC) and ethylene carbonate (EC) electrolyte exhibit irreversible reactions only on the first discharge. These irreversible reactions are associated with electrolyte decomposition and cause the formation of a passivating film or solid electrolyte interphase on the surface of the carbon. The amount of electrolyte decomposition is proportional to the specific surface area of the carbon electrode. When all the available surface area is coated with the film of decomposition products, further decomposition reactions stop. In subsequent cycles, these cells exhibit excellent reversibility and can be cycled without capacity loss.
Chitosan tailor‐made films: the effects of additives on barrier and mechanical properties

With the aim of achieving ‘tailor‐made’ chitosan films, the effects of several variables on the properties of chitosan films were studied. These variables were chitosan concentration and molecular weight of thermally depolymerized chitosan, addition of lipids (palmitic acid, beeswax or carnauba wax) and plasticizer (glycerol). The water vapour transmission rate (WVTR) and mechanical properties of these films were measured. The innovative feature of this study is that it provides specific information to support the design of tailor‐made films. These can only be formulated when the effects of the important variables are well understood. It was found that WVTR was reduced by 57% in film made from chitosan that had been thermally treated for 7 h at 100°C (molecular mass 13.7 kDa), while in the emulsion films, the WVTR was increased by incorporation of palmitic acid, beeswax or carnauba wax incorporation. The mechanical properties (tensile strength and elongation at break) were improved when glycerol was used as plasticizer, resulting in more elastic films (increasing the elongation at break by 62%).

Simultaneous Voltammetric Determination of Zn, Cd and Pb at Bismuth Nanopowder Electrodes with Various Particle Size Distributions

Effect of particle size distribution on sensor characteristics of nano-Bi fixed electrode has been investigated using square wave anodic stripping voltammetry. Bi nanopowders with various particle size distributions were synthesized by gas condensation (GC) method with the change of chamber pressure. As the chamber pressure decreased, the size of Bi nanopowder became smaller with narrower distribution due to a shorter residence time of Bi vapor. The square wave anodic stripping voltammograms (SWASV) showed well-defined and highly reproducible peaks at −1.2 V, −0.8 V and −0.6 V (vs. SCE), which are closely related to the oxidation of Zn, Cd and Pb, respectively. The sensitivity and detection limit of the nano-Bi fixed electrode were quantitatively estimated from the analyses of SWASV. From the results, it is concluded that as the size of Bi nanopowder becomes smaller with narrower particle size distribution, the sensitivity and detection limit of sensor electrode for Zn, Cd and Pb are improved, which is ascribed to the increase in electrochemical-active surface area.
Bubble drag and mass transfer in non‐newtonian fluids: Creeping flow with power‐law fluids

The drag and mass-transfer characteristics of a gas bubble moving in power-law non-Newtonian fluids are examined analytically in terms of the rheological properties of the system. An approximate solution for the case of creeping flow around circulating bubbles shows that the mass-transfer coefficient is enhanced for pseudoplastics and depressed for dilatants compared to the situation for Newtonian fluids. Some preliminary experimental results in support of the analysis are presented. On examine analytiquement, d'apres les proprietes rheologiques du systeme, les proprietes de friction et de transfert de masse d'une bulle de gaz qui se deplace dans des fluides non-newtoniens et soumis a la loi d'energie. Une solution approximative, dans le cas du mouvement ascendant autour de bulles en mouvement, indique une augmentation du coefficient de transfert de masse pour leg pseudo-plastiques et une diminution de celui-ci pour les produits expansibles, en comparaison de ce qui se passe pour les liquides newtoniens. On presente certains resultats d'experiences qui confirment l'analyse precitee.
