Authors: Mahdian Mitra , Sadeghi Narges , Mohammady Mina
Published: February 2022

Background and aims: Communication is a key component of professional nursing care. This study aimed at evaluating the effects of empathetic techniques education for nurses on resilience and spiritual well-being (SWB) among mothers with preterm neonates in neonatal intensive care unit (NICU). Methods: This cluster randomized controlled trial was conducted in 2018 using a two-group pretest-posttest design. Main participants were 68 mothers of preterm neonates in the NICUs of Montazeri and Amin hospitals in Isfahan, Iran. Nurses in the intervention hospital (i.e. Montazeri hospital) were provided with empathy techniques education in five weekly sessions in one month. After that, mothers in both groups completed the Connor-Davidson Resilience Scale and the SWB Scale both at the time of their neonates’ NICU admission and at the time of their neonates’ NICU discharge. Data were analyzed using the SPSS software (v. 22.0). Results: The pretest mean scores of resilience and SWB were respectively 79.74±12.78 and 175.6±11.95 in the control group and 78.0±16.9 and 176.67±16.0 in the intervention group. At posttest, these values were 78.32±12.12, 176.53±11.40, 92.0±13.77, and 186.0±12.5, respectively. Although the between-group differences respecting the pretest mean scores of resilience and SWB were not statistically significant (P>0.05), the posttest mean scores of resilience and SWB in the intervention group were significantly greater than the control group (P<0.05). Conclusion: Empathy techniques education is effective in significantly improving resilience and SWB among the mothers of preterm neonates in NICU. Therefore, this intervention is recommended for nurses in NICU.

Background and aims: Stress and anxiety during coronary angiography (CA) can lead to serious complications such as cardiac dysrhythmias, coronary artery spasm, and coronary artery rupture. This study aimed to evaluating the effects of clinical simulation on stress, anxiety, and hemodynamic parameters among the candidates for CA. Methods: This clinical trial was conducted on eighty candidates for CA. Participants were conveniently recruited from Tehran Heart Center, Tehran, Iran, and randomly allocated to a control and an intervention group through block randomization with a block size of 2. The Beck Anxiety Inventory, the Cohen Perceived Stress Scale, and a datasheet for hemodynamic parameters were used to assess participants’ anxiety, stress, and hemodynamic parameters before and after the study intervention. Participants in the intervention group received routine care services and a clinical simulation intervention, while participants in the control group solely received routine care services. Data were analyzed using the chi-square, independent-sample t, and paired-sample t tests. Results: The mean scores of stress and anxiety and the mean values of systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) significantly decreased in the intervention group (P<0.05), but did not significantly change in the control group (P>0.05). The pretest posttest differences in the means of stress, anxiety, SBP, DBP, and HR in the intervention group were significantly greater than the control group (P<0.05). Conclusion: Clinical simulation is effective in significantly reducing stress, anxiety, and hemodynamic parameters among the candidates for CA. Therefore, clinical simulation is recommended before CA.

Published: February 2022

Background and aims: Anxiety is a major problem among the candidates for surgery. This study aimed at investigating the effects of preoperative nursing visit (PNV) on anxiety and hemodynamic parameters among the candidates for general surgeries. Methods: This quasi-experimental study was conducted in 2018 on 104 candidates for general surgeries conveniently recruited from Imam Khomeini hospital, Islamabad-e Gharb, Iran. Participants were randomly assigned to a control and an intervention group. Participants in the control group received routine car services, while participants in the intervention group received both routine care services and a 30–60-minute PNV one day before surgery. Their anxiety and hemodynamic parameters were assessed before the intervention and before surgery. Data were collected using a demographic questionnaire, a data sheet for hemodynamic parameters, and Spielberger State-Trait Anxiety Inventory, and were analyzed using the SPSS software (v. 22.0). Results: There were no significant between-group differences regarding the pretest mean values of state and trait anxiety, heart rate (HR), and systolic blood pressure (SBP) and diastolic blood pressure (DBP) (P>0.05). However, the posttest mean values of state and trait anxiety, HR, and systolic and diastolic blood pressures in the intervention group were significantly less than the control group (P<0.05). Moreover, all these mean values significantly decreased in the intervention group (P<0.05). Conclusion: PNV is effective in significantly reducing state and trait anxiety and hemodynamic parameters among the candidates for general surgeries and hence, can be used to minimize preoperative physiological and psychological problems.

Published: February 2022

Background and aims: Stroke is the first leading cause of disability in adults. Long-term disability after stroke necessitates long-term caregiving by family members. The family caregivers (FCGs) of patients with stroke (PWS) experience different problems and hence, require self-management (SM) skills. The aim of this study was to assess the effects of an SM program based on Strauss and Corbin’s SM model on perceived social support (PSS) among the FCGs of PWS. Methods: This quasi-experimental study was conducted in 2019–2020. Participants were eighty FCGs of PWS who were hospitalized in Kashani hospital, Shahrekord, Iran. They were purposefully- recruited and randomly allocated to a control and an intervention group. An SM program based on Strauss and Corbin’s SM model was implemented in six ninety-minute sessions for participants in the intervention group. The Multidimensional Scale of PSS was used for PSS assessment before, immediately after, and two months after the intervention. Data were analyzed using the SPSS software (v. 16.0). Results: There was no significant difference between the groups in terms of the pretest mean score of PSS (P=0.76), while the mean score of PSS in the intervention group was significantly greater than the control group at both posttests (P<0.05). Moreover, the mean score of PSS in the control group did not significantly change across the three measurement time points (P>0.05), but significantly increased in the intervention group (P<0.05). Conclusion: SM program based on Strauss and Corbin’s SM model is effective in significantly improving PSS among the FCGs of PWS. Therefore, nurses and other healthcare providers can use this program for the FCGs of PWS.

Published: February 2022

Background and aims: Death anxiety (DA) is associated with stress and impaired immunity and thereby, puts individuals at risk for coronavirus disease 2019 (COVID-19). The aim of this study was to assess DA and its predictors among the companions of hospitalized patients with COVID-19. Methods: This descriptive-analytical study was conducted in 2020 on 200 companions of patients with COVID-19 hospitalized in Imam Khomeini, BouAli, and Razi hospitals in Sari and Qaemshahr, Iran. Sampling was performed conveniently. Data were collected using a demographic and clinical characteristics questionnaire for patients, a demographic and clinical characteristics questionnaire for companions, and Templer DA Scale. The SPSS software (v. 21.0) was used for data analysis via the independent sample t test, chi-square test, Pearson’s correlation analysis, and multiple linear regression analysis. Results: The mean score of DA was 47.21±10.62 (in the possible range of 15–75). Participants’ DA had significant relationship with their gender, their patients’ anorexia and arterial oxygen saturation, and COVID-19 among other family members (P<0.05). Participants’ gender, patients’ anorexia and arterial oxygen saturation, and COVID-19 among other family members significantly explained 0.066% of the total variance of DA (P=0.002). The strongest predictors of DA were arterial oxygen saturation (β=0.17; P=0.01) and gender (β=0.15; P=0.0). Conclusion: The companions of hospitalized patients with COVID-19 experience high levels of DA and hence, interventions are needed to reduce their DA.

Проведено исследование активности процессов эриптоза, общей антиоксидантной активности и концентрации лактоферрина в плазме крови у детей с ЖДА до и после лечения. У пациентов с ЖДА после приема ферропрепаратов увеличивается процент клеток с повышенным содержанием свободного кальция в популяции эритроцитов, что указывает на активацию процессов эриптоза. При дефиците железа возрастает содержание лактоферрина в плазме крови с максимальным значением у детей в возрасте 0-3 месяцев. Снижение общей антиоксидантной активности плазмы крови детей с ЖДА на фоне ферротерапии обусловлено усилением оксидантного стресса, что в дальнейшем необходимо учитывать при применении протоколов ферротерапии и обосновании назначения антиоксидантов при ЖДА.

The investigation of the activity of eryptosis, total antioxidant activity and lactoferrin concentration in the blood plasma of children with IDA before and after treatment was made. In children with IDA, after taking iron supplements, the percentage of erythrocytes with a high level of free calcium increases, which indicates the activation of eryptosis processes. While iron deficiency lactoferrin concentration in plasma raised with a maximum in a group of children 0-3-month-old. A decrease in the total antioxidant activity of blood plasma in children with IDA during treatment with iron drugs is due to an increase in oxidative stress. In the future, this must be taken into account when using ferro treatment protocols and justifying the use of antioxidants in IDA.

Диагностика тромбоцитопатий (ТП) имеет свои сложности. Чаще всего ТП проявляются носовыми кровотечениями, меноррагиями и другими кровотечениями слизистых. Поэтому при наличии в анамнезе кровотечений по микроциркуляторному типу необходимо проводить подробный сбор анамнеза и соответствующие диагностические исследования. Оценку функциональной активности тромбоцитов в большинстве случаев осуществляют методом агрегометрии. Современной лабораторной технологией является импедансная агрегатометрия, которая позволяет проводить исследование в цельной крови, т. е. в условиях, максимально приближенных к физиологическим. В представленном исследовании в ретроспективный анализ включили показатели агрегации тромбоцитов 31 ребенка, которых обследовали на предмет патологии тромбоцитов. Тромбоцитопения являлась критерием исключения. Полученные результаты согласовывались с данными литературы о диагностической значимости агрегатометрии у детей с подозрением на ТП.

The diagnosis of thrombocytopathies (TP) has its own complexities. Most often, TP are manifested by nosebleeds, menorrhagias and other mucosal bleeding. Therefore, if there is a history of microcirculatory bleeding, it is necessary to conduct a detailed history collection and appropriate diagnostic studies. Evaluation of the functional activity of platelets is generally carried out by the method of aggregometry. A modern laboratory technology is impedance aggregatometry, which makes it possible to conduct research in whole blood, i. e. in conditions as close as possible to physiological. In the presented study, the indicators of platelet aggregation of 31 children examined for platelet pathology were included in the retrospective analysis. Thrombocytopenia was the exclusion criterion. The results obtained were consistent with the literature data on the diagnostic value of aggregatometry in children with suspected TP.

Laparoscopic correction is the main method of treating hiatal hernias. However, despite more than thirty years of experience, many issues remain controversial and require compilation and standardization. The authors have analyzed the latest scientific studies and recommendations on the treatment of hiatal hernias with a high level of evidence, which is presented in the form of a review with a comparison of their own experience in surgical treatment of 171 patients operated on for hiatal hernias. The risk of transition of an asymptomatic hiatal hernia to a clinically significant one is 1% per year, while observation, rather than active surgical tactics, is indicated. Only symptomatic hernias are subject to surgical treatment. Surgical intervention should include the following mandatory steps: dissection of the esophagealdiaphragmatic ligament with excision of the hernial sac while protecting the branches of the vagus nerve; dissection of both crura of diaphragm, transhiatal mobilization of the esophagus in the mediastinum to achieve the length of its intraabdominal segment of 2–3 cm; if a short esophagus is suspected, a mandatory step is to perform Collis gastroplasty; mobilization of the gastric fundus by dividing gastrointestinal ligament and short gastric arteries; creation of a fundoplication cuff on a calibration probe of at least 30–36 Fr. The choice of the fundoplication and cruroraphia methods did not significantly affect the long-term results of treatment. Laparoscopic interventions are the most effective way to treat patients with hiatal hernias, due to their safety, low trauma, low complication rate and the possibility of rapid rehabilitation of patients. The technique of surgical intervention needs a clarified standardization.

Published: February 2022

Na experimentação com animais de grande porte, principalmente com vacas leiteiras é muito comum à utilização de ensaios alternativos. Nesse tipo de ensaio os animais recebem em sequências dois ou mais tratamentos. As principais justificativas para o uso desse tipo particular de ensaio se devem ao alto custo dos animais e a heterogeneidade des[1]ses animais. Esses ensaios são classificados basicamente em dois tipos: Ensaios Rotativos (Changeover) e Ensaios de Reversão (Switch-back). Para garantir que os efeitos dos tratamentos sejam avaliados adequadamente, regras pré- -estabelecidas e restrições na casualização dos tratamentos são necessárias no planejamento de tais ensaios. Assim, o objetivo deste artigo é apresentar possíveis formas de se planejar delineamentos changeover e foi desenvolvida uma rotina no software R para a determinação do número de changeover balanceadas de uma ordem n, já que na literatura foi encontrado o número de possíveis changeover balanceadas apenas para experimentos com no máximo quatro tratamentos e a demonstração algébrica não era trivial até o momento de obter os resultados simulados. Conclui-se que o número de opções de se planejar em changeover é bem menor e mais restrito em comparação ao planejamento em quadrado latino.

Ionic liquid (IL)/solid interfaces are relevant to a broad range of physicochemical phenomena and technological processes such as catalysis, corrosion, electrochemistry, and lubrication. Hence, understanding the effect of substrate surface nature on the interfacial properties has a significant impact on improving technological processes in which interfacial properties are dominant. In this work, we investigated interfacial structures between 1-butyl-3-methylimidazolium hexafluorophosphate (BMI-PF6) IL and KBr crystal surfaces by frequency modulation atomic force microscopy utilizing a quartz tuning fork sensor. KBr(100) and (111) surfaces were used as the substrates, where the (100) surface is electrically neutral, and the (111) surface is highly charged. We investigated the influence of surface charge on their surface structures and interfacial solvation structures by atomic-scale topographic imaging and frequency shift versus distance curve measurement. The behavior of IL at these two interfaces was found to be significantly different due to these different surface properties.

Published: February 2022

In this study, we synthesized and evaluated graft copolymers with polystyrene (PSt) as side chains on poly {[N,N´-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′ -bithiophene)} [P(NDI2OD-T2)], which is a typical n-type semiconducting polymer applied to in organic photovoltaics due to its intense optical absorption for the visible light, and high electron affinity. A well-controlled structure was confirmed by 1H-NMR analysis. It was found that enhanced electron mobilities in graft copolymer films were observed compared with the homopolymer. In order to clarify the role of PSt chains and the origins of the enhanced mobility, UV–vis absorption, electrochemical, morphological and thermal characteristics, and crystalline nature were investigated. As the results, it is suggested that the improved mobilities were attributed to the enhanced growth of π–π stacks, and increased crystallinity induced by PSt graft chains.

Collecting data for 240 individuals from rural and urban regions, this study examines the possible determinants of number of extramarital affairs (EMANO) in a hill state (Sikkim) in India. Using Poisson, Zero Inflated Poisson (ZIP) and instrumental variable Poisson (IV Poisson) model, this study found that income; financial satisfaction and marital satisfaction has positive and significant effect on number of extramarital affairs. Religiousness and same caste marriage reduce the chance of having EMANO significantly. This study also found that the relationship between the number of years married and EMANO are nonlinear and the tendency of having extramarital affairs reduces once the married life reached 12-13 years on average. Level of significance and importance of the variables on EMANO differs between male and female population.

Introduction: Although digital thermometers have made the temperature recording easy, quick and safe, with the risk of mercury completely excluded, there is still a risk of transmission of infection from one individual to another. Infrared thermometers offer a non-touch, rapid and convenient method of temperature recording, with virtually no risk of disease transmission. We conducted a study to assess and compare temperature recordings from an infrared forehead thermometer and axillary digital thermometer during fever, and once the fever subsides. Methods: Hundred patients attending the out-patient department of Department of Pediatrics at Dr.B.R Ambedkar medical college and hospital from September 2019 to December 2019, or those admitted in the wards with a complaint of fever were screened using two techniques – Axillary temperature recording using a digital thermometer and a forehead temperature was recorded using a non-contact infrared forehead thermometer. Patients were given antipyretics to treat the fever and temperature was again recorded once the fever subsided using the same method. Two medical personnel were trained to screen and record the respective findings from each method and they were blinded from the other outcome of other recording. Results: The mean IFR temperature measured in the febrile phase was 100.85 (± 0.76), which was significantly higher than the mean AD temperature, 100.21 (± 0.74). (p-value <.0001). In the afebrile phase as well, the mean IFR temperature was significantly higher than the mean AD temperature. Conclusion: IFR thermometers do provide an advantage of no-touch technique over the digital thermometer. However, as the results showed a weak correlation between IFR and axillary digital recordings, it is suggested that IFR thermometers be used for screening of children for fever as it decreases the contact and reduces the infection.

Published: February 2022

All around the world, the Building Information Modeling (BIM) is transforming the architecture of engineering design and of construction industry. While it is in an early implementation stage in African Sub-saharan Countries, many construction regulators and project owners are beginning to enforce the BIM application from the project design stage to its commissioning. The aim of this research work is to provide an approach for designing industrial warehouses using BIM as it was done in the industrial zone of the Kribi Deep Sea port in Cameroon. The proposed methodology is presented in six steps: definition of BIM general requirements, design of the 3D BIM architectural model, sizing of wall and roof for specific requirements, design of the 3D BIM structural model, coordination of 3D BIM models and interference detection and creation of 4D BIM model. Results obtained from the application of BIM on the design of a warehouse, dedicated to preserve the natural and biological essence of cocoa and coffee products in a hostile marine environment, show that this methodology is easily appropriated and implemented by local design and construction engineers through available engineering software in the local market.

A Fare Share: A Proposed Solution to Address the Racial Disparity in Access to Public Transportation Funding in America
Authors: Swistara Michael
Published: February 2022

Black American households are up to six times less likely to own a car than white families and are four times more likely to rely on public transportation to meet their daily needs. Despite this, communities of color have seen consistent disinvestment in their transit infrastructure. Four hundred years of continued housing segregation combined with post-recession austerity policies and ongoing pro-automobile bias has exacerbated this disparity. This Note proposes a straightforward legislative tool to begin to combat this inequity. The proposed legislation would require that urbanized areas spend their public transit dollars according to the population density of the communities a given project would serve, create reporting requirements related to the racial and economic impact of transit projects, and establish a private right of action. In proposing this legislation, this Note evaluates the state of civil rights litigation as it pertains to transportation racism and draws lessons from other areas such as environmental law in order to put forth a simple solution that would have tangible effects across the country in both the short and long term.
