Published: May 2023

Abstract
Background
We aimed to examine the reliability and validity of Chengdu pediatric emergency triage criteria in order to provide a reference for the development of pediatric emergency triage within other hospitals.

Methods
We developed Chengdu pediatric emergency triage criteria based on the conditions/symptom, vital signs, and the Pediatric Early Warning Score system within our hospital using the Delphi method in 2020. The simulation scenario triage and real-life triage which were conducted in our hospital during January - March 2021, and the retrospective study of triage records extracted from our hospital’s health information system in February 2022, were used to measure the agreement in triage decisions between the triage nurses, and between the triage nurses and the expert team.

Results
For the 20 simulation cases, the Kappa value of triage decisions between the triage nurses was 0.6 (95% CI 0.352–0.849), and the Kappa value of triage decisions between the triage nurses and the expert team was 0.73 (95% CI 0.540–0.911). For the 252 cases in the real-life triage, the Kappa value of triage decisions between the triage nurses and the expert team was 0.824 (95% CI 0.680–0.962). For the 20,540 cases selected for the retrospective study of triage records, the Kappa value of triage decisions between the triage nurses was 0.702 (95% CI 0.691–0.713); that between Triage Nurse 1 and the expert team was 0.634 (95% CI 0.623–0.647); and that between Triage Nurse 2 and the expert team was 0.725 (95% CI 0.713–0.736). The overall agreement rate in triage decisions between the triage nurses and the expert team in the simulation scenario triage was 80%; that between the triage nurses and the expert team in the real-life triage was 97.6%; and that between the triage nurses in the retrospective study was 91.9%. In the retrospective study, the agreement rates in triage decisions between Triage Nurse 1 and the expert team, and between Triage Nurse 2 and the expert team, were 88.0% and 92.3%, respectively.

Conclusion
Chengdu pediatric emergency triage criteria that developed within our hospital is reliable and valid, and can promote rapid and effective triage by triage nurses.

Published: May 2023

Abstract
Background
Regular breast screening is one of the most effective ways to detect early signs of breast cancer but travel distance to cancer-diagnostic facilities can affect breast screening attendance. Yet, limited studies have examined the impact of distance to cancer-diagnostic facilities on clinical breast screening behaviour among women in sub-Saharan Africa (SSA). This study examined the influence of travel distance to a health facility on clinical breast screening behaviour in five SSA countries: Namibia, Burkina Faso, Cote D’Ivoire, Kenya, and Lesotho. The study further assessed variations in clinical breast screening behaviour across diverse socio-demographic characteristics of women.

Methods
A sample of 45,945 women was drawn from the most recent Demographic and Health Surveys (DHS) for the included countries. The DHS uses 2-stage stratified cluster sampling to select nationally representative samples of women (15–49) and men (15–64) via a cross-sectional design. Proportions and binary logistic regression were used to examine associations between the women’s socio-demographic characteristics and breast screening attendance.

Results
The overall proportion of survey participants who underwent clinical breast cancer screening was 16.3%. Travel distance to a health facility had a significant (p < 0.001) impact on clinical breast screening behaviour as 18.5% of participants who self-reported distance as “not a big problem” attended clinical breast screening compared to 10.8% who self-reported distance as “a big problem”. The study further found that various socio-demographic factors were significantly associated with breast cancer screening uptake, including age, education level, media exposure, wealth status, parity, contraceptive use, health insurance coverage, and marital status. The multivariate analysis controlling for other factors confirmed the strong association between distance to health facilities and screening uptake.

Conclusions
The study found that travel distance is a significant factor affecting clinical breast screening attendance among women in the selected SSA countries. Furthermore, the likelihood of breast screening attendance varied depending on different women’s characteristics. It is crucial to prioritise breast screening interventions, particularly among the disadvantaged women identified in this study, to achieve maximum public health benefits.
The role of the California tier system in controlling population mobility during the COVID-19 pandemic

Published: May 2023

Abstract
Background
Policies to restrict population mobility are a commonly used strategy to limit the transmission of contagious diseases. Among measures implemented during the COVID-19 pandemic were dynamic stay-at-home orders informed by real-time, regional-level data. California was the first state in the U.S. to implement this novel approach; however, the effectiveness of California’s four-tier system on population mobility has not been quantified.

Methods
Utilizing data from mobile devices and county-level demographic data, we evaluated the impact of policy changes on population mobility and explored whether demographic characteristics explained variability in responsiveness to policy changes. For each California county, we calculated the proportion of people staying home and the average number of daily trips taken per 100 persons, across different trip distances and compared this to pre-COVID-19 levels.

Results
We found that overall mobility decreased when counties moved to a more restrictive tier and increased when moving to a less restrictive tier, as the policy intended. When placed in a more restrictive tier, the greatest decrease in mobility was observed for shorter and medium-range trips, while there was an unexpected increase in the longer trips. The mobility response varied by geographic region, as well as county-level median income, gross domestic product, economic, social, and educational contexts, the prevalence of farms, and recent election results.

Conclusions
This analysis provides evidence of the effectiveness of the tier-based system in decreasing overall population mobility to ultimately reduce COVID-19 transmission. Results demonstrate that socio-political demographic indicators drive important variability in such patterns across counties.

Published: May 2023

AbstractBackgroundImmunotherapy is currently applied in the first-line treatment regimens for numerous advanced cancers, especially advanced lung cancer. Immune-related adverse events (irAEs) resulting from immunotherapy can vary in severity and cause a substantial symptom burden to patients. However, there are limited data on symptom burden in patients with advanced lung cancer following immunotherapy. To address this deficit, this study aims to provide insight into the symptom burden and severity through patient-reported outcome measurements and conduct an analysis of temporal trends and clinical consequences of symptom burden in patients with advanced lung cancer receiving combination immunotherapy.MethodsWe will prospectively recruit 168 eligible patients from 14 hospitals in China. Eligible patients will be aged ≥ 18 years, pathologically diagnosed with locally advanced or stage IV primary lung cancer without surgical indications, and agreed to receive immunotherapy in combination with other therapies. The primary outcome of this study is the symptom burden of patients during the immunotherapy course. Longitudinal symptom data will be collected using the MD Anderson Symptom Inventory–Lung Cancer module (MDASI-LC) and the symptomatic irAEs scale at baseline (once before treatment) and weekly after treatment, until 1 month after the last treatment cycle has been completed. The trajectory of symptom burden following combination immunotherapy will be depicted, and by linking it to clinical outcomes (the secondary outcome and exploratory outcome of this study), the consequence of symptom burden in patients with advanced lung cancer receiving combination immunotherapy will be examined further.DiscussionThis study intends to establish longitudinal symptom trajectories in patients with lung cancer receiving immunotherapy, and explore its association with clinical outcomes. These findings may serve as an important reference for clinicians in the symptomatic management of patients with lung cancer receiving immunotherapy.Trial registration numberChiCTR2200061540.

Published: May 2023

Abstract
Background
Recurrent and metastatic thyroid cancer is more invasive and can transform to dedifferentiated thyroid cancer, thus leading to a severe decline in the 10-year survival. The thyroid-stimulating hormone receptor (TSHR) plays an important role in differentiation process. We aim to find a therapeutic target in redifferentiation strategies for thyroid cancer.

Methods
Our study integrated the differentially expressed genes acquired from the Gene Expression Omnibus database by comparing TSHR expression levels in the Cancer Genome Atlas database. We conducted functional enrichment analysis and verified the expression of these genes by RT-PCR in 68 pairs of thyroid tumor and paratumor tissues. Artificial intelligence-enabled virtual screening was combined with the VirtualFlow platform for deep docking.

Results
We identified five genes (KCNJ16, SLC26A4, TG, TPO, and SYT1) as potential cancer treatment targets. TSHR and KCNJ16 were downregulated in the thyroid tumor tissues, compared with paired normal tissues. In addition, KCNJ16 was lower in the vascular/capsular invasion group. Enrichment analyses revealed that KCNJ16 may play a significant role in cell growth and differentiation. The inward rectifier potassium channel 5.1 (Kir5.1, encoded by KCNJ16) emerged as an interesting target in thyroid cancer. Artificial intelligence-facilitated molecular docking identified Z2087256678_2, Z2211139111_1, Z2211139111_2, and PV-000592319198_1 (-7.3 kcal/mol) as the most potent commercially available molecular targeting Kir5.1.

Conclusion
This study may provide greater insights into the differentiation features associated with TSHR expression in thyroid cancer, and Kir5.1 may be a potential therapeutic target in the redifferentiation strategies for recurrent and metastatic thyroid cancer.
Neonatal reference intervals for thyroid stimulating hormone and free thyroxine assayed on a Siemens Atellica® IM analyzer: a cross sectional study
Authors: Omuse Geoffrey , Kawalya David , Mugaine Patrick , Chege Assumpta , Maina Daniel 
Published: May 2023

Abstract
Background
Deriving population specific reference intervals (RIs) or at the very least verifying any RI before adoption is good laboratory practice. Siemens has provided RIs for thyroid stimulating hormone (TSH) and free thyroxine (FT4) determined on their Atellica® IM analyzer for all age groups except the neonatal age group which provides a challenge for laboratories that intend to use it to screen for congenital hypothyroidism (CH) and other thyroid disorders in neonates. We set out to determine RIs for TSH and FT4 using data obtained from neonates undergoing routine screening for CH at the Aga Khan University Hospital, Nairobi, Kenya.

Methodology
TSH and FT4 data for neonates aged 30 days and below were extracted from the hospital management information system for the period March 2020 to June 2021. A single episode of testing for the same neonate was included provided both TSH and FT4 were done on the same sample. RI determination was performed using a non-parametric approach.

Results
A total of 1243 testing episodes from 1218 neonates had both TSH and FT4 results. A single set of test results from each neonate was used to derive RIs. Both TSH and FT4 declined with increase in age with a more marked decline seen in the first 7 days of life. There was a positive correlation between logFT4 and logTSH (rs (1216) = 0.189, p = < 0.001). We derived TSH RIs for the age groups 2–4 days (0.403–7.942 µIU/mL) and 5–7 days (0.418–6.319 µIU/mL), and sex specific RIs for males (0.609–7.557 µIU/mL) and females (0.420–6.189 µIU/mL) aged 8–30 days. For FT4, separate RIs were derived for the age groups 2–4 days (1.19–2.59 ng/dL), 5–7 days (1.21–2.29 ng/dL) and 8–30 days (1.02–2.01 ng/dL).

Conclusion
Our neonatal RIs for TSH and FT4 are different from those published or recommended by Siemens. The RIs will serve as a guide for the interpretation of thyroid function tests in neonates from sub-Saharan Africa where routine screening for congenital hypothyroidism using serum samples is done on the Siemens Atellica® IM analyzer.
Retrospective analysis of dental implants immediately placed in extraction sockets with periapical pathology: immediate implant placement in infected areas
Authors: Çolak Sefa , Demïrsoy Mustafa Sami 
Published: May 2023

Abstract
Background
The aim of this study is to examine the survival rates of immediate implants placed in extraction sockets with chronic periapical pathology.

Methods
69 patients and 124 immediate implants were included in the study. The patients included in the study were examined in 3 groups. Group 1: Patients who underwent tooth extraction with periapical pathology and immediate implant placement. Group 2: patients who underwent tooth extraction with periapical pathology, immediate implant placement and guided bone regeneration. Group 3: Patients who underwent tooth extraction with periapical pathology, sinus lift procedure and immediate implant placement. In statistical analysis, t-test and Anova analysis were used in the evaluation of quantitative data, cross-tables and chi-square (χ2) test were used in the evaluation of classified qualitative data. Statistical significance was determined as p < 0.05.

Results
It was observed that 116 (95.55%) of 124 implants were successful and 8 (4.45%) failed. The success rate was 97.2% in Group 1, 93.5% in Group 2 and 81.8% in Group 3. A significant correlation was found between the study groups and implant success in terms of χ2 test (p = 0.037). A significant relationship was found between smoking and success in terms of the χ2 test (p = 0.015).

Conclusions
High survival rates are observed for immediate implant placement in sockets with periapical pathology. The success rates observed in guided bone regenerations simultaneously with immediate implant placement are at satisfactory levels. In cases where simultaneous sinus lifting procedures are required, the success rates were observed to be significantly lower. In case of adequate curettage and debridement in sockets with periapical pathology, high implant survival rates are observed. As the complexity of the surgical procedure increases, treatment protocols may progress in safer ways.

AbstractSingle-parent adolescents are vulnerable individuals and it is necessary to improve their health, particularly during epidemics. This study aimed to investigate the effects of virtual logotherapy (VL) on health-promoting lifestyle (HPL) among single-parent adolescent girls during the COVID-19 pandemic. This single-blind randomized clinical trial was conducted on 88 single-parent adolescent girls recruited from the support organization for vulnerable individuals in Tehran, Iran. They were randomly allocated to a control and an intervention group through block randomization. Participants in the intervention group received VL in three–five person groups in 90 min biweekly sessions. The Adolescent Health Promotion Short-Form was used to assess HPL. Data were analyzed using the SPSS software (v. 26.0) and through the independent-sample t, Chi-square, Fisher’s exact, and Mann–Whitney U tests. There was no significant difference between the intervention and the control groups respecting the pretest mean score of HPL (73.58±16.74 vs. 72.80±9.30; P=0.085). However, the posttest mean score of HPL in the intervention group (82 with an interquartile range of 78–90) was significantly more than the control group (71.50 with an interquartile range of 63.25–84.50) (P=0.001). Moreover, after adjusting the effects of the significant between-group differences respecting pretest mean scores, the pretest–posttest differences of the mean scores of HPL and all its dimensions in the intervention group were significantly more than the control group (P<0.05). VL is effective in significantly improving HPL among single-parent adolescent girls. Healthcare authorities are recommended to use VL for health promotion among single-parent adolescents.Trial registrationThis research was registered (17/05/2020) in the www.thaiclinicaltrials.org with registration number: TCTR20200517001.
The effects of normal vaginal birth simulation training on the clinical skills of midwifery students: a quasi-experiment study
Authors: Pajohideh Zahra Sadat , Mohammadi Solmaz , Keshmiri Fatemeh , Jahangirimehr Azam , Honarmandpour Azam 
Published: May 2023

Abstract
Background
Vaginal birth management is vital to midwifery education and practice in which midwives are most likely to be directly involved. This situation requires strong cognitive, technical, communicational, and teamwork skills. Therefore, the present study was conducted to evaluate the effect of normal vaginal birth simulation training before formal clinical education on the clinical skills of midwifery students compared with routine clinical education.

Methods
This quasi-experimental study was conducted at the Shoushtar Faculty of Medical Sciences from September 2018 to August 2021. Sixty-one midwifery students participated in the intervention group (n = 31) and in the control group (n = 30). The intervention group participated in the simulation-based training before entering the formal clinical education courses. The control group received no simulation-based training before their formal clinical education. The clinical skills of these students for performing normal vaginal birth in the real field were evaluated by observational examination in the three years (fourth, fifth, and sixth semesters). Data were analyzed by descriptive (mean, SD, and percentage) and inferential statistics (independent t-test and chi-square). A P-value less than 0.05 was considered significant.

Results
The mean score of midwives’ skills in the control group was (28.10 ± 3.42) and in the intervention group, it was (31.15 ± 4.30). The difference in the skill score between the groups was statistically significant (3.40 ± 0.68). The results showed that in the intervention group, 29 students (93.93%) were evaluated from a good to an excellent level, while only ten students (32.71%) in the control group achieved a good level, and others (n = 30) were evaluated at a low level (p < .001).

Conclusion
The results of the present study indicated that the simulation situation for critical skills, such as vaginal birth skills, was significantly more effective than workplace-based learning situations.
”Putting words to their feelings”– civic communicators’ perceptions and experiences of an in-depth course on mental health for newly settled refugee migrants in Sweden
Authors: Al-Adhami Maissa , Wångdahl Josefin , Salari Raziye , Åkerman Eva 
Published: May 2023

Abstract
Background
Newly settled refugee migrants face psychological stressors stemming from pre-, during- and post-migration experiences. In Sweden, mental health promotion is part of the health module in the civic orientation classes for newly settled refugee migrants. Training courses are offered to civic communicators and workshop leaders to facilitate communication about mental health; however, the training is seldom evaluated. In the current study, we aim to explore civic communicators’ perceptions and experiences of an in-depth mental health training course in relation to observed needs among newly settled refugee migrants.

Method
We interviewed ten civic communicators that had partaken in the in-depth training course on mental health. All respondents had prior migratory experience and worked as civic communicators in their native languages. The interviews were semi-structured and data were analyzed using thematic analysis.

Results
Three themes were identified: (1) Intertwined mental health needs related to migration, (2) Multi-layered barriers to addressing mental health, and (3) Becoming aware of the mental health journey. One overarching theme was arrived at through synthesizing the three themes ‘Acquired new tools to lead reflective conversations about mental health and well-being’.

Conclusion
The in-depth mental health training course led to the attainment of new knowledge and new tools enabling civic communicators to lead reflective conversations about mental health and well-being with newly settled refugee migrants. Mental health needs were related to pre- and post-migration experiences. Barriers to talking about mental health included stigma and a lack of arenas to promote the mental health of refugee migrants. Increasing knowledge among civic communicators can facilitate the promotion of mental self-help capacity and resilience among newly settled refugee migrants.
Analysis and validation of aging-related genes in prognosis and immune function of glioblastoma
Authors: Mu Jianhua , Gong Jianan , Shi Miao , Zhang Yinian 
Published: May 2023

Abstract
Background
Glioblastoma (GBM) is a common malignant brain tumor with poor prognosis and high mortality. Numerous reports have identified the correlation between aging and the prognosis of patients with GBM. The purpose of this study was to establish a prognostic model for GBM patients based on aging-related gene (ARG) to help determine the prognosis of GBM patients.

Methods
143 patients with GBM from The Cancer Genomic Atlas (TCGA), 218 patients with GBM from the Chinese Glioma Genomic Atlas (CGGA) of China and 50 patients from Gene Expression Omnibus (GEO) were included in the study. R software (V4.2.1) and bioinformatics statistical methods were used to develop prognostic models and study immune infiltration and mutation characteristics.

Results
Thirteen genes were screened out and used to establish the prognostic model finally, and the risk scores of the prognostic model was an independent factor (P < 0.001), which indicated a good prediction ability. In addition, there are significant differences in immune infiltration and mutation characteristics between the two groups with high and low risk scores.

Conclusion
The prognostic model of GBM patients based on ARGs can predict the prognosis of GBM patients. However, this signature requires further investigation and validation in larger cohort studies.
