Authors: Wu Wenjuan , Li Baoguang , Xie Tao 
Published: April 2023

Abstract
Background
There are few reports on the timing of onset and the symptoms of enterovirus A71 (EV-A71) infection, which can easily be misdiagnosed. This study aimed to explore the clinical characteristics of children with severe EV-A71 infection.

Methods
This retrospective observational study included children with severe EV-A71 infection admitted to Hebei Children’s Hospital between January 2016 and January 2018.

Results
A total of 101 patients were included: 57 males (56.4%) and 44 females (43.6%). They were 1–13 years of age. The symptoms were fever in 94 patients (93.1%), rash in 46 (45.5%), irritability in 70 (69.3%), and lethargy in 56 (55.4%). There were 19 (59.3%) patients with abnormal neurological magnetic resonance imaging [pontine tegmentum (n = 14, 43.8%), medulla oblongata (n = 11, 34.4%), midbrain (n = 9, 28.1%), cerebellum and dentate nucleus (n = 8, 25.0%), basal ganglia (n = 4, 12.5%), cortex (n = 4, 12.5%), spinal cord (n = 3, 9.3%), and meninges (n = 1, 3.1%)]. There was a positive correlation between the ratio of neutrophil count and white blood cell count in cerebrospinal fluid in the first 3 days of the disease (r = 0.415, P < 0.001).

Conclusion
The clinical symptoms of EV-A71 infection are fever and/or skin rash, irritability, and lethargy. Some patients have abnormal neurological magnetic resonance imaging. The white blood cell count in the cerebrospinal fluid of children with EV-A71 infection may increase alongside neutrophil counts.

Abstract
Background
During the COVID-19 pandemic, increased workload and stress could have increased mental health problems (anxiety and depression) in military personnel. However, the number of studies in military members is scarce, especially in regard to mental health. The objective of this study was determine the prevalence and factors associated with depression and anxiety in Peruvian military personnel.

Methods
We undertook an analytical cross-sectional study. The survey was distributed face to face between November 02 and 09, 2021, during the second wave of the COVID-19 pandemic among the military personnel. We used some instruments to measure depression (Patient Health Questionnaire, PHQ-9), anxiety (Generalized Anxiety Disorder, GAD-7), insomnia (Insomnia Severity Index, ISI), food insecurity (Household Food Insecurity Access Scale, HFIAS), physical activity (International Physical Activity Questionnaires, IPAQ-S), resilience (abbreviated CD-RISC), and fear of COVID-19 scale. The exclusion criteria included those who did not completely fill out the evaluation instruments.

Results
We analyzed the data of 615 military personnel that participated in the survey. Of them, 93.7% were male and the median age was 22 years old. There was a prevalence of 29.9% and 22.0% in regard to depression and anxiety symptoms, respectively. In addition, it was found that being married (PR: 0.63; 95% IC: 0.42–0.94), having a relative with mental health problems (PR: 2.16), having experienced food insecurity (PR: 1.48), insomnia (PR: 2.71), fear of COVID-19 (PR: 1.48), and a high level of resilience (PR: 0.65) were factors associated with depression. In regard to anxiety, the factors associated were working for more than 18 months since the beginning of the COVID-19 pandemic (PR: 0.52), a high level of resilience (PR: 0.50; 95% IC: 0.33–0.77), insomnia (PR: 3.32), fear of COVID-19 (PR: 2.43).

Conclusion
We found a prevalence of symptoms of depression and anxiety of 29.9% and 22.0%, respectively. In regard to the factors that attenuate depression, we can mention being married and having resilience; and among the aggravating factors, having a relative with mental health problems, food insecurity, insomnia, and fear of COVID-19. Finally, anxiety increased through working time, insomnia, and fear of COVID-19.

Abstract
Background
Nurturing effective physician-patient relationships is essential to the provision of patient-centred care. Palliative care physicians may apply boundary-crossings or breaches in professional standards to nurture effective physician-patient relationships. Being highly individualized and shaped by the physician’s narratives, clinical experience, and contextual considerations, boundary-crossings are susceptible to ethical and professional violations. To better appreciate this concept, we employ the Ring Theory of Personhood (RToP) to map the effects of boundary-crossings on the physician’s belief systems.

Methods
As part of the Tool Design SEBA methodology, a Systematic Evidence-Based Approach (SEBA) guided systematic scoping review was employed to guide the design of a semi-structured interview questionnaire with palliative care physicians. The transcripts were simultaneously content and thematically analysed. The themes and categories identified were combined using the Jigsaw Perspective and the resulting domains formed the basis for the discussion.

Results
The domains identified from the 12 semi-structured interviews were catalysts and boundary-crossings. Boundary-crossings attempt to address threats to a physician’s belief systems (catalysts) and are highly individualized. Employ of boundary-crossings depend on the physician’s sensitivity to these ‘catalysts’, their judgement and willingness to act, and their ability to balance various considerations and reflect on their actions and their ramifications. These experiences reshape belief systems, understandings of boundary-crossings and may influence decision-making and practice, underscoring the potential for greater professional breaches when unchecked.

Conclusion
Underlining its longitudinal effects, the Krishna Model underscores the importance of longitudinal support, assessment and oversight of palliative care physicians, and lays the foundation for a RToP-based tool to be employed within portfolios.

AbstractIntroductionSince learning with high educational quality requires an advanced intervention. This study seeks to answer how many puzzles game-based training can improve knowledge and cognitive function of surgical technology students in CABG surgery and its sequence, as well as the tools and equipment used in each stage of surgery and the sequence of their preparation.Materials and methodsThis study was carried out as a quasi-experimental single-group pre-test-post-test, during which, after designing a puzzle game including various stages of surgery (from the preparation of the patient for surgical sutures and the necessary equipment to perform each stage), 18 people from third-year surgical technology students who met the inclusion criteria were entered in the study by convenience sampling method and based on the sample size determined using a similar study and they participated in the test of knowledge and cognitive function, that the validity and reliability were measured, before the intervention and 14 days after the intervention (using a puzzle game). Data were analyzed using descriptive and Wilcoxon statistical tests.ResultsAfter the withdrawal of 2 people, 15 person (93.80 per cent) of the students were female, the average age of students was 21.87 ± 0.71 years, and 50% (8 people) of them were 22 years old. Also, the average score of the end-of-semester exam of the heart surgery technology course was 15.19 ± 2.30 (the lowest score was 11.25, and the highest score was 18.63), and the score of 43.80% (7 people) of them were in the range of 15.01–17.70, and their average of grade point average was 17.31 ± 1.10 (the lowest grade point average is 15 and the highest grade point average is 19.36) and grade point average 75% (11 people) of students were 16–18. The average scores of knowledge(5.75 ± 1.65 vs. 2.68 ± 0.79) and cognitive performance(6.31 ± 2.57 vs. 2.00 ± 1.09) of students in the post-intervention phase were significantly higher than the pre-intervention phase (P < 0.0001).ConclusionThe results of the present study showed that the use of puzzle games in CABG surgery training led to a significant improvement in the knowledge and cognitive performance of surgical technology students regarding the stages of CABG surgery and its sequence, as well as the tools and equipment used in each stage of surgery and the sequence of their preparation.
Genomic and transcriptomic analyses support a silk gland origin of spider venom glands

Published: April 2023

Abstract
Background
Spiders comprise a hyperdiverse lineage of predators with venom systems, yet the origin of functionally novel spider venom glands remains unclear. Previous studies have hypothesized that spider venom glands originated from salivary glands or evolved from silk-producing glands present in early chelicerates. However, there is insufficient molecular evidence to indicate similarity among them. Here, we provide comparative analyses of genome and transcriptome data from various lineages of spiders and other arthropods to advance our understanding of spider venom gland evolution.

Results
We generated a chromosome-level genome assembly of a model spider species, the common house spider (Parasteatoda tepidariorum). Module preservation, GO semantic similarity, and differentially upregulated gene similarity analyses demonstrated a lower similarity in gene expressions between the venom glands and salivary glands compared to the silk glands, which questions the validity of the salivary gland origin hypothesis but unexpectedly prefers to support the ancestral silk gland origin hypothesis. The conserved core network in the venom and silk glands was mainly correlated with transcription regulation, protein modification, transport, and signal transduction pathways. At the genetic level, we found that many genes in the venom gland-specific transcription modules show positive selection and upregulated expressions, suggesting that genetic variation plays an important role in the evolution of venom glands.

Conclusions
This research implies the unique origin and evolutionary path of spider venom glands and provides a basis for understanding the diverse molecular characteristics of venom systems.

Abstract

Background
Data on the economic burden of RSV-associated illness will inform decisions on the programmatic implementation of maternal vaccines and monoclonal antibodies. We estimated the cost of RSV-associated illness in fine age bands to allow more accurate cost-effectiveness models to account for a limited duration of protection conferred by short- or long-acting interventions.

Methods
We conducted a costing study at sentinel sites across South Africa to estimate out-of-pocket and indirect costs for RSV-associated mild and severe illness. We collected facility-specific costs for staffing, equipment, services, diagnostic tests, and treatment. Using case-based data we calculated a patient day equivalent (PDE) for RSV-associated hospitalizations or clinic visits; the PDE was multiplied by the number of days of care to provide a case cost to the healthcare system. We estimated the costs in 3-month age intervals in children aged < 1 year and as a single group for children aged 1–4 years. We then applied our data to a modified version of the World Health Organization tool for estimating the mean annual national cost burden, including medically and non-medically attended RSV-associated illness.

Results
The estimated mean annual cost of RSV-associated illness in children aged < 5 years was US dollars ($)137,204,393, of which 76% ($111,742,713) were healthcare system incurred, 6% ($8,881,612) were out-of-pocket expenses and 13% ($28,225,.801) were indirect costs. Thirty-three percent ($45,652,677/$137,204,393) of the total cost in children aged < 5 years was in the < 3-month age group, of which 52% ($71,654,002/$137,204,393) were healthcare system incurred. The costs of non-medically attended cases increased with age from $3,307,218 in the < 3-month age group to $8,603,377 in the 9–11-month age group.

Conclusions
Among children < 5 years of age with RSV in South Africa, the highest cost burden was in the youngest infants; therefore, interventions against RSV targeting this age group are important to reduce the health and cost burden of RSV-associated illness.
User fee exemption and malaria treatment-seeking for children under five in a Cameroonian health district: a cross-sectional study

Published: April 2023

Abstract
Background
In Cameroon, malaria contributes significantly to the morbidity and mortality of children under 5 years old. In order to encourage adequate treatment-seeking in health facilities, user fee exemptions for malaria treatment have been instituted. However, many children are still brought to health facilities in the late stage of severe malaria. This study sought to determine the factors affecting the hospital treatment-seeking time of guardians of children under 5 years within the context of this user fee exemption.

Methods
This was a cross-sectional study conducted at three randomly selected health facilities of the Buea Health District. A pre-tested questionnaire was used to collect data on the treatment-seeking behaviour and time of guardians, as well as potential predictors of this time. Hospital treatment sought after 24 h of noticing symptoms was denoted as delayed. Continuous variables were described using medians while categorical variables were described using percentages. A multivariate regression analysis was used to determine the factors affecting malaria treatment-seeking time of guardians. All statistical tests were done at a 95% confidence interval.

Results
Most of the guardians made use of pre-hospital treatments, with self-medication being practiced by 39.7% (95% CI 35.1–44.3%) of them. A total of 193 (49.5%) guardians delayed seeking treatment at health facilities. Reasons for delay included financial constraints and watchful waiting at home, during which guardians waited and hoped their child could get better without requiring medicines. Guardians with estimated monthly household incomes denoted as low/middle were significantly more likely (AOR 3.794; 95% CI 2.125–6.774) to delay seeking hospital treatment. The occupation of guardians was another significant determinant of treatment-seeking time (AOR 0.042; 95% CI 0.003–0.607). Also, guardians with tertiary education were less likely (AOR 0.315; 95% CI 0.107–0.927) to delay seeking hospital treatment.

Conclusions
This study suggests that despite user fee exemption, other factors such as educational and income levels of guardians affect malaria treatment-seeking time for children aged under five. Therefore, these factors should be considered when enacting policies aimed at increasing access of children to health facilities.
Nonlinear analysis of heart rate variability signals in meditative state: a review and perspective
Authors: Deka Bhabesh , Deka Dipen 
Published: April 2023

Abstract
Introduction
In recent times, an upsurge in the investigation related to the effects of meditation in reconditioning various cardiovascular and psychological disorders is seen. In majority of these studies, heart rate variability (HRV) signal is used, probably for its ease of acquisition and low cost. Although understanding the dynamical complexity of HRV is not an easy task, the advances in nonlinear analysis has significantly helped in analyzing the impact of meditation of heart regulations. In this review, we intend to present the various nonlinear approaches, scientific findings and their limitations to develop deeper insights to carry out further research on this topic.

Results
Literature have shown that research focus on nonlinear domain is mainly concentrated on assessing predictability, fractality, and entropy-based dynamical complexity of HRV signal. Although there were some conflicting results, most of the studies observed a reduced dynamical complexity, reduced fractal dimension, and decimated long-range correlation behavior during meditation. However, techniques, such as multiscale entropy (MSE) and multifractal analysis (MFA) of HRV can be more effective in analyzing non-stationary HRV signal, which were hardly used in the existing research works on meditation.

Conclusions
After going through the literature, it is realized that there is a requirement of a more rigorous research to get consistent and new findings about the changes in HRV dynamics due to the practice of meditation. The lack of adequate standard open access database is a concern in drawing statistically reliable results. Albeit, data augmentation technique is an alternative option to deal with this problem, data from adequate number of subjects can be more effective. Multiscale entropy analysis is scantily employed in studying the effect of meditation, which probably need more attention along with multifractal analysis.

Methods
Scientific databases, namely PubMed, Google Scholar, Web of Science, Scopus were searched to obtain the literature on “HRV analysis during meditation by nonlinear methods”. Following an exclusion criteria, 26 articles were selected to carry out this scientific analysis.

AbstractBackgroundDespite efforts from the government and developmental partners to eliminate gender-based violence, intimate partner violence (IPV) remains a pervasive global health and human rights problem, affecting up to 753 million women and girls globally. Few studies on IPV have focused on pregnant and parenting adolescent (PPA) girls in Africa, although the region has the highest rates of adolescent childbearing. This limited attention results in the neglect of pregnant and parenting adolescents in policies and interventions addressing IPV in the region. Our study examined IPV prevalence and its individual, household, and community-level correlates among pregnant and parenting adolescent girls (10–19 years) in Blantyre District, Malawi.MethodsWe collected data from a cross-section of pregnant and parenting adolescent girls (n = 669) between March and May 2021. The girls responded to questions on socio-demographic and household characteristics, lifetime experience of IPV (i.e., sexual, physical, and emotional violence), and community-level safety nets. We used multilevel mixed-effect logistic regression models to examine the individual, household, and community-level factors associated with IPV.ResultsThe lifetime prevalence of IPV was 39.7% (n = 266), with more girls reporting emotional (28.8%) than physical (22.2%) and sexual (17.4%) violence. At the individual level, girls with secondary education (AOR: 1.72; 95% CI: 1.16–2.54), who engaged in transactional sex (AOR: 2.29; 95% CI: 1.35–3.89), and accepted wife-beating (AOR: 1.97; 95% CI: 1.27–3.08) were significantly more likely to experience IPV compared to those with no education/primary education, who never engaged in transactional sex and rejected wife beating. Girls aged 19 (AOR: 0.49; 95% CI: 0.27–0.87) were less likely to report IPV than those aged 13–16. At the household level, girls with fair and poor partner support had higher odds of experiencing IPV, but the effect size did not reach a significant level in the parsimonious model. A high perception of neighborhood safety was associated with a lower likelihood of experiencing IPV (AOR: 0.81; 95% CI: 0.69–0.95).ConclusionIntimate partner violence is rife among pregnant and parenting adolescent girls in Malawi, underscoring the need for appropriate interventions to curb the scourge. Interventions addressing IPV need to target younger adolescents, those engaging in transactional sex, and those having weaker community-level safety nets. Interventions to change social norms that drive the acceptance of gender-based violence are also warranted.

Published: April 2023

AbstractIncreasing evidence has shown that the NOD-like receptor protein 1 (NLRP1) inflammasome is associated with Aβ generation and deposition, which contributes to neuronal damage and neuronal-inflammation in Alzheimer's disease (AD). However, the specific mechanism of NLRP1 inflammasome in the pathogenesis of AD is still unclear. It has been reported that autophagy dysfunction can aggravate the pathological symptoms of AD and plays an important role in regulating Aβ generation and clearance. We hypothesized that NLRP1 inflammasome activation may induce autophagy dysfunction contributing to the progression of AD. In the present study, we observed the relationship between Aβ generation and NLRP1 inflammasome activation, as well as AMPK/mTOR mediated-autophagy dysfunction in WT 9-month-old (M) mice, APP/PS1 6 M and APP/PS1 9 M mice. Additionally, we further studied the effect of NLRP1 knockdown on cognitive function, Aβ generation, neuroinflammation and AMPK/mTOR mediated autophagy in APP/PS1 9 M mice. Our results indicated that NLRP1 inflammasome activation and AMPK/mTOR mediated-autophagy dysfunction are closely implicated in Aβ generation and deposition in APP/PS1 9 M mice, but not in APP/PS1 6 M mice. Meanwhile, we found that knockdown of NLRP1 significantly improved learning and memory impairments, decreased the expressions of NLRP1, ASC, caspase-1, p-NF-κB, IL-1β, APP, CTF-β, BACE1 and Aβ1-42, and decreased the level of p-AMPK, Beclin 1 and LC3 II, and increased the level of p-mTOR and P62 in APP/PS1 9 M mice. Our study suggested that inhibition of NLRP1 inflammasome activation improves AMPK/mTOR mediated-autophagy dysfunction, resulting in the decrease of Aβ generation, and NLRP1 and autophagy might be important targets to delay the progression of AD.
