Impact of premature rupture of membranes on clinical outcomes of extremely premature infants: A propensity score matching study
Authors: Cao Jing-Ke , Liu Chang-Geng , Wang Dan , Li Qiu-Ping 
Published: March 2023

BackgroundPremature rupture of membranes (PROM) is a common cause of extremely premature infants (EPIs) and also leads to adverse preterm complications. However, the effect of PROM on EPIs remains contradictory. This study used propensity score matching (PSM) to adjust the baseline characteristics to explore the impact of PROM on clinical outcomes of extremely premature infants (EPIs).MethodsMedical data of 470 EPIs at gestational age &lt; 28weeks who received prenatal examination in our hospital between January 1, 2015 and December 31, 2020 were analyzed retrospectively. According to the presence or absence of PROM, they were divided into a PROM group and a non-PROM group. Ten covariates including birth weight, male sex, artificial conception, cesarean delivery, 5-min Apgar score ≤ 7, oligohydramnios, gestational hypertension, preeclampsia, antenatal steroid use, and complete steroid treatment were matched 1:1 by PSM. The major complication occurrence and mortality during hospitalization were compared between the two groups by t-test, nonparametric test or x2 test.ResultsAmong the 470 infants enrolled, 157 (33.4%) were in the PROM group and 313 in the no-PROM group. After matching the ten confounding factors,276 cases were successfully enrolled. The incidence of early pulmonary hypertension (EPH) and severe retinopathy of prematurity (ROP) in the PROM group were higher than those in the no-PROM group [44.2% (61/138) vs. 29.0% (40/138); 34.8% (48/138) vs. 21.7% (30/138), x2 = 6.886 and 5.790, both P &lt; 0.05]. However, there was no significant difference in the in-hospital mortality and the incidence of other major complications between the two groups (all P &gt; 0.05).ConclusionsPROM increased the incidence of EPH and severe ROP in EPI, but had no significant impact on in-hospital mortality, length of hospital stay, and the incidence of other complications.

This paper describes preparing radiopure molybdenum trioxide powder enriched with Mo-100 isotope for the AMoRE-II experiment. AMoRE-II, the second phase of the AMoRE experiments, will search for the neutrinoless double-beta decay (0νDBD) of the 100Mo isotope using over 100 kg of 100Mo embedded in 200 kg of ultra-pure Li2100MoO4 bolometric crystals. Efficient purification technology was developed and adapted to purify 100MoO3 powder with a 5 kg per month production capacity. Based on the ICP-MS analysis of purified powder, the 232Th and 238U were reduced to &lt;9.4 μBq/kg and &lt;50 μBq/kg, respectively. The concentrations of potassium, transition metals, and heavy metals were lower than 1 ppm. HPGe counting confirmed the reduction of progenies from the 232Th and 238U decay chains, reporting upper limits of &lt;27 μBq/kg for 228Ac and &lt;16 μBq/kg for 228Th. The 226Ra activity was acceptable at 110 ± 30 μBq/kg. In the last 3 years, 100 kg of pure 100MoO3 powder was produced. The production yield for the final purified product was above 90%, while irrecoverable losses were under 1.5%, and all by-products could be recycled further.

Objective: In this study, we compared the enhancement of blood vessels and liver parenchyma on enhanced computed tomography (CT) of the upper abdomen with two concentrations of contrast media (400 and 300 mg I/mL) based on similar iodine delivery rate (IDR) of 0.88 and 0.9 g I/s and iodine load of 450 mg I/kg.Methods: We randomly assigned 160 patients into two groups: iomeprol 400 mg I/mL (A group) and iohexol 300 mg I/mL (B group). The CT attenuation values of the main anatomical structures in the two groups with different scanning phases were measured and the image quality of the two groups was analyzed and compared. The peak pressure and local discomfort (including fever and pain) during contrast medium injection were recorded.Results: The mean attenuation value of the abdominal aorta was 313.6 ± 29.6 in the A group and 322.4 ± 30.1 in the B group during the late arterial phase (p = 0.8). Meanwhile, the mean enhancement values of the portal vein were 176.2 ± 19.3 and 165.9 ± 24.5 in the A and B groups, respectively, during the portal venous phase (p = 0.6). The mean CT values of liver parenchyma were 117.1 ± 15.3 and 108.8 ± 18.7 in the A and B groups, respectively, during the portal venous phase (p = 0.9). There was no statistical difference in image quality, peak injection pressure (psi), and local discomfort between the two groups (p &gt; 0.05).Conclusion: When a similar IDR and the same iodine load are used, CT images with different concentrations of contrast media have the same subjective and objective quality, and can meet the diagnostic needs.

ObjectiveThis review aimed to systematically examine the characteristics and outcomes of family-based psychosocial interventions offered to adult Latino patients with cancer and their caregivers.MethodsWe searched six databases from their inception dates through June 2022. Studies were eligible for inclusion if they (1) targeted both adult Latino patients diagnosed with cancer and their adult caregivers or reported subgroup analyses of Latino patients and caregivers; (2) included family-based psychosocial interventions; (3) used randomized controlled trial (RCT) or quasi-experimental designs; and (4) were published in English, Spanish or Portuguese. Members of our multidisciplinary team assessed the risk of bias in the reviewed studies using the Cochrane Collaboration's Risk of Bias Tool.ResultsOur database searches yielded five studies. The studies were conducted in the U.S. and Brazil. Three studies were RCTs, and two used quasi-experimental designs. The sample sizes ranged from 18 to 230 patient-caregiver dyads. These studies culturally adapted the intervention contents and implementation methods and involved bilingual interventionists. The interventions had beneficial effects on multiple aspects of psychosocial outcomes for both patients and caregivers. We also identified methodological limitations in the reviewed studies.ConclusionsFindings from this systematic review help deepen our understanding of family-based psychosocial interventions for Latinos affected by cancer. The small number of psychosocial interventions focused on adult Latino cancer patients and their caregivers is concerning, considering that Latino populations are disproportionally burdened by cancer. Future research needs to design and evaluate culturally-appropriate interventions to support Latino patients and families who cope with cancer.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=274993, identifier CRD42021274993.
“The show must go on”: How Paralympic athletes safeguarded their mental well-being and motivation to train for the postponed Tokyo 2020 games
Authors: Van Biesen Debbie , Morbee Sofie 
Published: March 2023

IntroductionAfter the decision to postpone the Tokyo 2020 Games due to the COVID-19 pandemic, athletes had to adjust to a novel situation with feelings of uncertainty and insecurity. Grounded in Self-Determination Theory, this study was the first to examine whether different motivational profiles among Paralympic athletes can be identified, and to link these profiles with the athletes’ emotional, cognitive, and performance-related outcomes in times of a pandemic.MethodsFive months before the start of the Paralympic Games, the participants (N = 32; mean age = 33.2 ± 6.8 years) completed an online questionnaire measuring their demographics, basic psychological needs, perceived stress, depressive symptoms, general well-being, and motivational self-regulation strategies. Two months after the Games, they completed a second online questionnaire measuring their actual and perceived performance at the past Games.ResultsThrough K-means cluster analysis, three distinct clusters were identified based on the athletes’ dominant type of motivation, these are, dominantly amotivated (n = 11), autonomously motivated (n = 12), and controlled motivated (n = 9). Comparisons of athletes’ emotional, cognitive, and performance-related outcomes depending on their motivational profile revealed that the athletes with a dominantly amotivated profile had the least adaptive outcomes (i.e., low need satisfaction, high need frustration, and more depressive symptoms). Athletes with a dominantly autonomously motivated profile made less use of controlling self-motivating strategies compared to the other two profiles. Moreover, their actual performance at the Paralympic Games was better.DiscussionAlthough none of the athletes were at severe risk for depression or showed extremely high levels of stress, these results confirm that improving the quality of athletes’ motivation can safeguard their well-being and enhance performance in Paralympic Sports.

Published: March 2023

IntroductionDifferent measures to prevent and control the spread of SARS-CoV-2 have been implemented in German schools. Decisions regarding such measures should be informed by evidence regarding their effectiveness, and their unintended consequences for health and society. A multi-stakeholder panel was convened to develop an evidence- and consensus-based guideline for school measures, using the novel WHO-INTEGRATE framework. Developing a guideline to inform decision-making outside of the clinical realm during a public health emergency was unprecedented in Germany. This study aims to identify lessons learnt for similar endeavours by addressing the following research question: What were the strengths and weaknesses of the guideline development process as perceived by the different groups involved?MethodsFifteen semi-structured interviews were conducted virtually. We recruited participants aiming to include the perspectives of all groups contributing to the guideline development, including both panel members (scientists, practitioners, school family and observers) and the guideline secretariat. For analysis, we carried out deductive-inductive thematic qualitative text analysis according to Kuckartz, structuring findings using a category system.ResultsDue to time pressure, the guideline secretariat was heavily involved not only in synthesising the evidence but also in developing and drafting recommendations. Participants critically reflected on certain methods-related decisions, including the development of draft recommendations and application of the WHO-INTEGRATE framework by scientists only. The full potential of the framework might not have been harnessed. Participants’ understanding of relevant and valid evidence varied, and the available evidence base was limited. Participants represented different types of expertise, notably expertise informed by scientific evidence and expertise grounded in lived experience, influencing their involvement in the guideline development process and discussions during meetings.ConclusionDeveloping an evidence- and consensus-based public health guideline in only three months was challenging, notably because of the involvement of a broad range of stakeholders and the use of a novel Evidence-to-Decision framework, both unprecedented in Germany. Learning from this process with a view to “institutionalising” the development of public health guidelines and refining methods can contribute to more evidence-informed public health decision-making in Germany and beyond, in general and during a public health emergency.
Information and communication technology development and health gap nexus in Africa
Authors: Megbowon Ebenezer Toyin , David Oladipo Olalekan 
Published: March 2023

IntroductionDevelopment of information and communication technology has been identified as a tool for fast and effective information gathering and dissemination, and as a means through which almost every social and economic sector (including the health sector) could achieve economic, operational, and service delivery efficiencies that can enable the realization of targeted outcomes. ICT can serve as a tool for achieving international agreements (including the Alma Ata Declaration of 1978), thereby accelerating the achievement of various global development targets.MethodsConsequently, based on a sample of 38 countries from 2000 to 2018, this study investigates the effect of ICT development on the health gap, and whether the effect varies by gender and sub-region in Africa. The dependent variable (health gap) was measured as the difference between the achieved life expectancy at birth of 60 years and the Alma Ata Declaration of 1978 targeted life expectancy at birth of 60 years. The main independent variables are ICT indicators (ICT index, mobile cellular subscriptions, and internet access), while the gross domestic product (GDP), which is the measure of economic growth, healthcare expenditure, urbanization, and labor market outcome, is employed as control variables. The effect was examined using Driscoll-Kraay standard errors, feasible generalized least squares (FGLS), and panel-corrected standard error (PCSE).Results and discussionThe findings of the Driscoll-Kraay standard errors estimation technique supported by those of FGLS and PCSE suggest that ICT does act as an indispensable stimulator for Africa to significantly exceed the international health target of life expectancy at birth of 60 years. It can be concluded that African leaders need to take advantage and maximize the health-enhancing potential of the internet component of ICT through relevant policies that would improve internet coverage, connectivity, and access for individuals and health institutions.
Impact of green space on residents' wellbeing: A case study of the Grand Canal (Hangzhou section)
Authors: Xia Yuke 
Published: March 2023

IntroductionIn this study aimed to discuss the importance of the combination of cultural heritage management and green development for urban development by analyzing the upgrading and renovation of the Grand Canal (Hangzhou section) as a successful case. In recent years, green development has risen to prominence as a paradigm shift. Additionally, culture, as an engine to drive urban development, has received more attention.MethodsThis research used a hybrid approach to examine the importance of combining green development with cultural heritage management. The qualitative method was an interview analysis of 13 residents living in the Hangzhou section of the Grand Canal. Based on the analysis of multiple water quality variables in Hangzhou from 1998 and 2014 to 2021, the empirical results proved that it is feasible to integrate green development (environment and economy) into the cultural heritage management of the case study area.Results and discussionThe results further prove that only through an understanding of the relationship between cultural heritage and green development can a virtuous cycle of development be created, thereby promoting the continuous development of a unique and historically significant urban area. The results of this study suggest that, in the development of mega-cities, although the preservation and inheritance of historical and cultural heritage conflicts with the green development of modern cities, a successful example has been explored in Hangzhou, including grassroots governance efforts like Gongshu District. There, the two factors can be mutually compatible and promote each other, enhancing the well-being and happiness of local residents.

Objectives: The primary objective of this cross-sectional study is to investigate perceived stress, perceived social support, satisfaction with online learning, and coping strategies among working mothers in Jordan during the COVID-19 pandemic.
Methods: A total of 204 working mothers participated in an online survey. Four instruments were employed to analyze the study variables. Those instruments were Perceived Stressors Scale (PSS), Multidimensional Scale of Social Support (MSPSS), the Brief Coping Orientation to Problems Experienced (B-COPE) Inventory, and Distance Learning Satisfaction Scale (DLSAT). We used descriptive statistics, Pearson's correlation coefficients, and internal consistency for all variables in analyzing data for all variables.
Results: The results revealed that working mothers reported a high level of perceived stress (M = 44.15, SD = 7.25), a low level of perceived social support (M = 29.78, SD = 9.41), a low level of satisfaction with online learning (M = 17.50, SD = 6.60), and a moderate level of effectively coping with their life circumstances (M = 60.56, SD = 11.07). Furthermore, the mothers’ perceived stressors, perceived social support, and satisfaction with children’s online learning were all significantly associated with the score of coping strategies.
Conclusions: As working mothers are of the most vulnerable groups who was affected during the corona-virus disease (COVID-19) pandemic, the results in this study are significant in providing essential support and resources for them to cope with stress in the future and identify effective coping strategies for their well-being.

Authors: PYATNITSA-HORPYNCHENKO N.К. 
Published: March 2023

Foundation. Present-day developments impose new requirements on the professional education of doctors, taking into account the introduction of modern standards of the educational process, Ukraine’s desire to integrate into the European space, and the difficult socio-economic conditions that have developed at the present time. One of the key tasks of medical education is the perfect mastery of professional competencies by future doctors, which is the key to their ability to solve practical problems of varying complexity based on the acquired knowledge and skills, and is designed to ensure successful professional activity in the future.
Goal. Definition of the essence of the concept of “professional competence”, its components and conditions for the formation among medical university students.
Materials and methods. An analytical review of published scientific papers on the topic under consideration was conducted.
Results. Medical practice is a special occupation that requires thorough special training of the doctor. Implementation of knowledge and skills acquired during training is specific to the profession of a doctor, which determines his/her future career and the opportunity to integrate into the medical professional community, adequately interact with patients and colleagues, actively exchange experience, and search for problems of a medical and social nature solutions. To implement practical activities in the future, a medical student must have not only certain professional qualifications, but also personal qualities that are important components of his/her professional competence. Based on the analysis of the literature, the basic components that form the basis of a doctor’s professional competence, their component parts and conditions of formation are identified.
Conclusions. The profession-oriented approach aims to create favorable learning conditions for teachers and adequate interactionbetween participants in the educational process, which will ensure that students master the professional competencies defined by the standard of education and then implement them in the professional activity. The rapid development of medical science and practice leads to high competition in the labor market, requires constant self-development, self-improvement and self-organization from the doctor to form a high level of professional competence and professional maturity. Important importance in this process is given to personal qualities, such as purposefulness, empathy, sociability, tolerance.
