Abstract
Background
Previous studies conducted in North America, Europe, and East Asia (10, 16, 20, 21) reported gender disparities in the provision of bystander CPR for patients with out of hospital cardiac arrest (OHCA). However, it remains unknown whether similar disparities exist in the Middle Eastern and Gulf regions. The primary objective of this study is to evaluate gender differences in the provision of bystander CPR for patients with OHCA in Qatar.
Methods
Retrospective analysis of data obtained from Hamad Medical Corporation OHCA registry in the State of Qatar (2016–2022). We included adults with non-traumatic and EMS-attended OHCA. We used multilevel logistic regression to examine the association between gender and provision of bystander CPR.
Results
In total, 4283 patients were included. Of those, 3414 (79.7%) were males, 1639 (38.3%) arrested in public locations, and 1463 (34.2%) received bystander CPR. Unadjusted comparisons showed that females were significantly older than males (mean age: 62.2 vs. 52.7). Females had a lower proportion of OHCA occurring in public locations (15.1% vs. 44.2%) and a lower proportion of shockable rhythm (11.9 vs. 27.5%). Regarding the outcome variable (provision of bystander CPR), the unadjusted analysis showed that the proportion of females who received bystander CPR was lower than that of males (29.2% vs. 35.4%, p < 0.001). However, after adjustment, we found no significant difference in provision of bystander CPR by gender (adjusted OR female vs. male 0.99, 95% CI 0.84–1.20, p = 0.97). In the subgroup who arrested in public locations, the analysis revealed females had greater odds of receiving bystander CPR (adjusted OR female vs. male 1.47, 95% CI 1.10–1.82, p = 0.04).
Conclusions
Overall, bystander CPR was less common in female gender, after adjustment for other covariates, including arrest location, we found no significant gender differences in provision of bystander CPR. We also observed that females were found to have a lower incidence of cardiac arrest in public locations. Nevertheless, if females were to experience cardiac arrest in a public location, they would be more likely to receive CPR. Further research is required to explain the observed differences in provision of bystander CPR.

Abstract
Background: Multiple sclerosis (MS) has a significant effect on the quality of life and fatigue of affected people. Performing self-care behaviors improves the quality of life of MS patients and reduces their fatigue. Effective educational methods can be used to help these patients. This study was conducted with the aim of comparing the effect of patient-centered and family-centered self-care training programs on the quality of life and fatigue of patients with multiple sclerosis.
Methods:This is a quasi-experimental study that was conducted on the MS patients referred to the Iranian MS Association. Sampling was done by convenience method, and the participants were divided into three groups of intervention 1, intervention 2 and control. To create a random sequence in the three groups, blocks of nine were used. The control group received no intervention but the intervention groups 1 and 2 received the desired training in the form of workshop with the difference that in the intervention group 2, the patient participated in the training sessions along with one of his/her family members. The phone call follow-up was continued for 8 weeks after the last training session. The questionnaire of quality of life in patients with MS (MSQOL-54), fatigue scale (FIS) and demographic information form were used for data collection. The collected data was analyzed by SPSS-16 statistical software, using descriptive and statistical statistics.
Result: A statistically significant difference in the mean scores of quality of life (P<0.001) and fatigue (P<0.001) was observed between both intervention groups and the control group. A statistically significant difference in the mean scores of quality of life (P<0.001) and fatigue was also observed between the intervention group 2 (family-centered training) and intervention group 1 (patient-centered training).
Conclusions: The family-centered self-care training method can be used in MS patients to improve their quality of life and fatigue.

Abstract
The fast-growing rhizobia-like strains S101T and S153, isolated from nodules of Glycine max in Sichuan, P.R. China, were characterized by using a polyphasic taxonomy approach. Growth was observed at 20–40°C (optimum, 28°C), pH 4.0–10.0 (optimum, pH 7) and with up to≤2.0% (w/v) NaCl (optimum, 0.01%) on Yeast Mannitol Agar (YMA) plates. 16S rRNA genes of strain S101T and Ciceribacter daejeonense L61T were 98.4% similar. The major cellular fatty acids of strain S101T were summed feature 8 (C18:1ω7c and/or C18:1ω6c) and C19:0 cyclo ω8c. The DNA G+C contents of S101T and S153 were 61.1 mol% and 61.3 mol%, respectively. The digital DNA–DNA hybridization (dDDH) relatedness and average nucleotide identity (ANI) values between S101T and the most closely related type strain C. daejeonense L61T were 46.2% and 91.4–92.2%, respectively. Therefore, we propose that the strains S101T and S153 represent a novel species with the name Ciceribacter sichuanense sp. nov. and strain S101T as the type strain (CGMCC 1.61309T= JCM 35649T).

Abstract
Background
In Rwanda, 37% of sexually active unmarried women are not using any contraceptive methods to space or limit the number of pregnancies. Thus, factors, reasons for not using contraceptives and intentions for future use are not well documented. We aimed to assess factors associated with the unmet need for family planning (FP), reasons and intentions for the future among sexually active unmarried women in Rwanda.
Method
Researcher-designed data abstraction form was used to conduct a secondary data analysis using Rwanda demographic and health survey (RDHS) 2019/2020 which had surveyed on 12,949 households, of whom 417 were sexually active unmarried women. Sociodemographic characteristics, reasons and intentions are presented using frequencies and percentages. Logistic regression models were fitted to identify factors associated with the unmet need for FP at 95% CI, with a probability value of ≤ 0.05.
Results
Out of 417 unmarried women, 156 (37%) were identified with an unmet need for family planning. The majority of women were aged between 15–24 years (n = 155, 37%), protestants (n = 224, 54%), richer wealth index (n = 105, 25%), owned medical insurance (n = 320, 77%) and 264 (63%) had between one to four children. Factors associated with unmet need for FP were: being richer (aOR: 0.46; 95% CI: 0.23–0.91; p = 0.025), richest wealth category (aOR = 0.435; 95% CI: 0.2091–0.905; p = 0.026), multiparty (aOR: 0.23; 95% CI: 0.13–0.42; p < 0.000) and nulliparous (aOR: 0.26; 95% CI: 0.11–0.59; p < 0.001). Amongst the 97 women who had provided reasons for not using FP, most cited reasons for not using FP in future were having infrequent sex (n = 46, 47.4%), nulliparous (n = 11, 11.3%) and fear of side effects (n = 7, 7.2%). While 73.1% (n = 114) of women had the intention to use FP in future.
Conclusion
We found that one in three unmarried women had an unmet need for FP. Richer, richest, nulliparous, and multiparous are less affected than their counterparts. Thus, need for tailored social behavioural change messages on FP for each female subpopulation (poor wealth categories and one to four children) when designing public health programs that will effectively address their FP unmet needs.

Published: May 2023

Abstract
Networks are essential for analyzing complex systems. However, their growing size necessitates backbone extraction techniques aimed at reducing their size while retaining critical features. In practice, selecting, implementing, and evaluating the most suitable backbone extraction method may be challenging. This paper introduces netbone, a Python package designed for assessing the performance of backbone extraction techniques in weighted networks. Its comparison framework is the standout feature of netbone. Indeed, the tool incorporates state-of-the-art backbone extraction techniques. Furthermore, it provides a comprehensive suite of evaluation metrics allowing users to evaluate different backbones techniques and select the best one based on their case study. We illustrate the flexibility and effectiveness of netbone through the US air transportation network analysis. We compare the performance of different backbone extraction techniques using the evaluation metrics. We also show how users can integrate a new backbone extraction method into the comparison framework. Netbone is publicly available as an open-source tool, ensuring its accessibility to researchers and practitioners. Promoting standardized evaluation practices contributes to the advancement of backbone extraction techniques and fosters reproducibility and comparability in research efforts. We anticipate that netbone will serve as a valuable resource for researchers and practitioners enabling them to make informed decisions when selecting backbone extraction techniques to gain insights into the structural and functional properties of complex systems.

Authors: Gao Sheng 
Published: May 2023

Abstract

Soluble solids content (SSC) and pH of red globe grapes are crucial measures of quality. In this paper, we used hyperspectral imaging technology to achieve nondestructive detection and distribution visualization of SSC and pH of red globe grapes. First, the hyperspectral images of samples were collected. Then, CARS, SPA, GA, IRIV were used to extract feature variables from raw spectral (RAW) information. The PLSR prediction models of samples were developed. By comparing the different prediction models, RAW-IRIV-PLSR was selected as the optimal model. Finally, the SSC and pH of the samples were calculated to obtain a grayscale image and perform a pseudo-color transformation to visualize the distribution of SSC and pH. By studying the classification of the maturity of samples, it was concluded that the best discriminant classification model of maturity was RAW-IRIV-ELM. Hyperspectral also provided a new method for maturity stage classification of red globe grapes.

Abstract
Background: Children with cancer who undergo immunosuppressive anti-cancer treatment are at risk of developing acute and long-term oral and dental complications. The study aimed to assess the attitudes toward dental and oral health of parents of children receiving anti-cancer treatment.
Methods: For this cross-sectional descriptive study, we arbitrarily distributed a questionnaire to the parents of 50 paediatric patients who were receiving anti-cancer treatment (study group) and 62 parents of healthy children (control group). The questionnaires assessed awareness towards oral and dental care.
Results: Among the study group, 90% of the respondents acknowledged awareness of the heightened importance of maintaining their children’s oral and dental health. Academic versus non-academic education of the mothers was associated with greater awareness of the importance of maintaining oral and dental health following the children's medical condition. Forty-percent of the parents of the study group reported having received this information from oncology doctors. Among the study group, 42% of the parents had not taken their child to a dentist, though 34% of the children had complained of oral pain. Among the control group, the respective proportions were 5% and 2%. During the course of anti-cancer treatment, 44% of the children in the study group had oral ulcerations and 22% had dry mouth.
Conclusions: Despite their awareness to the importance of their children’s dental and oral health, parents of children receiving anti-cancer treatment took their children for dental examinations less than did parents of healthy children. This study highlights the need for periodic referrals of children who are treated for cancer, to paediatric dental clinics.

Abstract
Background The silicified cell wall of diatoms, also known as frustule, shows huge potential as an outstanding bio-nanomaterial for hemostatic applications due to its high hemostatic efficiency, good biocompatibility, and ready availability. As the architectural features of the frustule determine its hemostatic performance, it is of great interest to develop an effective method to modify the frustule morphology into desired patterns to further improve hemostatic efficiency.Results In this study, the gene encoding Silicalemma Associated Protein 2 (a silicalemma-spanning protein) of Cyclotella cryptica (CcSAP2) was identified as a key gene in frustule morphogenesis. Thus, it was overexpressed (OE) and knocked down (KD), respectively. The frustule of the OE line showed no obvious alteration in morphology compared to the wild type (WT), while the size, specific surface area (BET), pore volume, and pore diameter of the KD strain changed greatly. Particularly, the KD frustules achieved a more pronounced coagulation effect and in vivo hemostatic performance than the WT strains. Such observations suggest that silicalemma proteins are ideal genetic encoding targets for manipulating frustule morphology and associated hemostatic properties. Furthermore, the Mantel test was adopted to identify the key morphologies associated with C. cryptica bleeding control. Finally, based on our results and recent advances, a silica coordinating assembly model was proposed.Conclusion This study explores a new strategy for enhancing the hemostatic efficiency of the frustule based on genetic morphology modification and may provide insights into a better understanding of the frustule morphogenesis mechanism.

Authors: ONAY Tuba , UÇAR ASLI 
Published: May 2023

Abstract
Background and aims: The purpose of this study is to determine which anthropometric measurement and ratio (BMI, waist circumference, hip circumference, waist-to-hip ratio, neck circumference, waist-height ratio, body shape index, body roundness index, visceral adiposity index) is a better indicator in healthy individuals with NAFLD and their biochemical parameters.
Methods: The study included 41 healthy persons diagnosed with non-alcoholic fatty liver disease between the ages of 30-64 in the gastroenterology outpatient clinic of Ankara Gülhane Training and Research Hospital. In the study, subjects were interviewed face-to-face using a questionnaire form that asked about their socio-demographic traits, anthropometric measurements, and biochemical markers.
Results: Individuals with NAFLD had greater triglyceride, VLDL cholesterol, AST, ALT, and GGT levels than healthy people, as well as lower HDL cholesterol levels (p<0,05). persons with NAFLD had higher averages of body weight, BMI, waist circumference, waist/height, hip circumference, waist/hip, neck circumference, body fat mass, body shape index, body roundness index, and visceral fat index than healthy persons (p<0,05). Waist circumference, BMI, waist/height ratio, body roundness index, and visceral adiposity index are the anthropometric parameters with the greatest performance requirements that can be employed in persons with NAFLD.
Conclusion: Conclusion; It is believed that following patients at risk for NAFLD under the supervision of dietitians and using these anthropometric measurements will play a useful role in preventing the disease's course, progression, and consequences.

Abstract

Background: The urgency of the climate crisis requires attention from biomedical research, not least clinical trials which can involve significant greenhouse gas emissions. The Low Carbon Clinical Trials (LCCT) Working Group set out a strategy to reduce the emissions of clinical trials, starting with the development of a method to measure their carbon footprint (CO2e).
Methods: As a first step, we developed a process map defining clinical trial core activities. Corresponding emission factors were sourced to convert activity data into greenhouse gas emissions. The subsequent method was piloted by application on two CRUK-funded trials (the international randomised sarcoma trial CASPS [ISRCTN63733470] and the UK cohort-based breast cancer trial PRIMETIME [ISRCTN41579286]). A guidance document defining the scope, method and assumptions was written to allow application to any clinical trial.
Results: Trial specific activities over and above routine care were grouped into 10 modules covering trial set up, conduct and closure. We identified emission factors for all trial activities within both trials and used them to estimate their total carbon footprint. The carbon footprint of CASPS, an international phase 2 clinical trial of an investigational medicinal product with 47 participants, was 72 tonnes CO2e, largely attributable to clinical trials unit emissions and staff travel. PRIMETIME, a UK-based phase 3 non-investigational medicinal product trial with 1962 patients, produced 89 tonnes CO2e, largely attributable to trial-specific in-person participant assessments.
Conclusion: We have developed a method and guidance that trialists can use to determine the carbon footprint of clinical trials. The guidance can be used to identify carbon hotspots where alternative approaches to trial design and conduct could reduce a trial footprint, and where methodology research is required to investigate the potential impact of interventions taken to reduce carbon emissions. We will continue to refine the guidance to increase the potential application and improve usability.

Abstract
Objective
This study aims to analyze the learning curve of percutaneous transforaminal endoscopic discectomy (PETD) with visualized foraminoplasty for the treatment of lumbar spinal stenosis (LSS).
METHODS
80 patients underwent PETD with visualized foraminoplasty between 1 January 2019 and 1 January 2022 were retrospectively reviewed. Clinical outcomes were evaluated by using the Visual Analogue Scale(VAS) of low back pain(LBP) and leg pain(LP), the Oswestry Disability Index (ODI), and Japanese Orthopaedic Association scores(JOA). The learning curve was assessed by CUSM analysis. According to the learning curve, of these 80 patients were divided into two groups: early group(38) and late group(n = 42) in chronological order for comparison.
Results
All cases were completed successfully with no conversion to open surgery. No major complications occurred, but 5 patients response to postoperative paresthesia. The mean follow-up time was 16.04 ± 2.62 months. The median operative time reduced from 92.5 (interquartile range(IQR), 80–100) minutes for the early group to 85 (IQR, 80–90) minutes for the late group (P < 0.05). After approximately 38 cases, the curve tends to plateau and is considered a learning plateau. Postoperatively, the VAS of LBP and LP, and ODI in the two groups decreased significantly, the JOA was considerably elevated during the follow-up. The total complication rate was 6.2%. There were no significant differences in ODI, VAS of LP and LBP, JOA and complication rates between the two groups.
CLUSIONS
PETD with visualized foraminoplasty for LSS performed by surgeons has a notable learning curve. The mastery level could be achieved with 38 cases.
