Abstract
Background
Proximal humerus fractures are often treated with a fixed-angle titanium plate osteosynthesis. Recently, plates made of alternative materials such as carbon fibre-reinforced polyetheretherketone (CFR-PEEK) have been introduced. This study presents the postoperative results of patients treated with a CFR-PEEK plate.

Methods
Patients with proximal humerus fractures treated with a CFR-PEEK plate (PEEKPower™ Humeral Fracture Plate (HFP)) were included. In follow-up examination, age and gender adjusted Constant-Murley Score (ACS), Subjective Shoulder Value (SSV), Quick Disabilities of the Arm, Shoulder and Hand Score (QDASH) and pain score (Visual Analog Scale (VAS)) were analyzed. General condition at follow-up was measured by European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L). Range of motion was recorded. In addition, radiographs at follow-up, unfavorable events and revision rate were analyzed.

Results
In total, 98 patients (66.0 ± 13.2 years, 74 females, 24 males) were reexamined. Mean follow-up was 27.6 ± 13.2 months. There were 15 2-part, 28 3-part and 55 4-part fractures. The functional scores showed good results: SSV 83.3 ± 15.6%, QDASH 13.1 ± 17.0 and ACS 80.4 ± 16.0. A 4-part-fracture, head split component, nonanatomic head shaft reposition and preoperative radiological signs of osteoarthritis were significant negative predictors for poorer clinical scores. Unfavourable events were observed in 27 patients (27.6%). Revision surgery was performed in 8 (8.2%) patients. Risk factors for an unfavourable event were female gender, age of 50 years and older, diabetes, affected dominant hand, 4-part fracture, head split and preoperative radiological signs of osteoarthritis.

Conclusion
There are several advantages of the CFR-PEEK plate (PEEKPower™ Humeral Fracture Plate (HFP)) such as the polyaxial screw placement and higher stability of locking screws. In summary, the CFR-PEEK plate osteosynthesis is a good alternative with comparable clinical results and some biomechanical advantages. Proximal humerus fractures show good clinical results after treatment with a CFR-PEEK plate. The revision rate and the risk of unfavorable events are not increased compared to conventional titanium plate osteosynthesis.

Authors: Dabaghi Shima , Ataei Seyed Ahmad , Taheri Ali 
Published: January 2023

Abstract
Background
Rhamnolipids are a group of the extracellular microbial surface-active molecules produced by certain Pseudomonas species with various environmental and industrial applications. The goal of the present research was to identify and optimize key process parameters for Pseudomonas aeruginosa PTCC 1074s synthesis of rhamnolipids utilizing soybean meal in solid state fermentation. A fractional factorial design was used to screen the key nutritional and environmental parameters to achieve the high rhamnolipid production. Response surface methodology was used to optimize the levels of four significant factors.

Results
The characterization of biosurfactant by TLC, FT-IR and H-NMR showed the rhamnolipids presence. In the optimum conditions (temperature 34.5 °C, humidity 80%, inoculum size 1.4 mL, and glycerol 5%), the experimental value of rhamnolipid production was 19.68 g/kg dry substrate. The obtained rhamnolipid biosurfactant decreased water's surface tension from 71.8 ± 0.4 to 32.2 ± 0.2 mN/m with a critical micelle concentration of nearly 70 mg/L. Additionally, analysis of the emulsification activity revealed that the generated biosurfactant was stable throughout a broad pH, temperature, and NaCl concentration range.

Conclusions
The current study confirmed the considerable potential of agro-industrial residues in the production of rhamnolipid and enhanced the production yield by screening and optimizing the significant process parameters.

Abstract
Introduction
Imperial College Teddy Bear Hospital (ICSM-TBH) is a student-led volunteering group, which uses interactive, play-based teaching to educate school pupils aged 5–7 years about healthy lifestyles and healthcare. During the COVID-19 pandemic, volunteering sessions shifted online. The aim of this study was to compare the value of online and in-person ICSM-TBH volunteering for volunteers and school pupils.

Methods
Undergraduate university students at Imperial College London (medicine can be taken as a first degree in the UK) who volunteered with ICSM-TBH between 2019 and 22 were invited to complete an anonymous online questionnaire evaluating their experiences of volunteering online and in-person through Likert-scale questions. Those who completed the questionnaire were also invited to an interview. Teachers who hosted online ICSM-TBH sessions were also invited to an in-person interview, exploring their view of their pupils’ experiences with these sessions. Questionnaire results were analysed through descriptive statistics. Interviews were analysed through inductive thematic analysis.

Results
Thirty-two university students completed the questionnaire. Of these, 9 experienced both in-person and online volunteering, all of whom preferred in-person volunteering. For those who only volunteered in-person, 92% reported that ICSM-TBH sessions were a positive experience, compared to 100% who volunteered online; 92% in person volunteers agreed or strongly agreed that ICSM-TBH volunteering in person improved their mood, compared to 89% online; and 100% agreed or strongly agreed that ICSM-TBH volunteering in person helped them feel part of a community, compared to 84% online. A total of 12 volunteers and 4 teachers were interviewed, from whom five themes emerged: interaction and engagement (interaction and engagement between pupils and volunteers was more readily achieved in-person); personal and professional development (both online and in-person sessions enabled volunteers to gain valuable skills); community and social (greater sense of community was established in-person); emotional wellbeing and enjoyment (both modalities were enjoyed by volunteers and pupils); and workload (online sessions were more convenient for volunteers but with risk of screen fatigue).

Conclusion
Overall, both in-person and online volunteering were of substantial benefit to volunteers and school pupils. However, most teachers and volunteers preferred in-person volunteering.

Abstract
Introduction
Professional burnout is characterized by loss of enthusiasm for work, cynicism, and a low sense of personal efficacy. Burnout may adversely affect medical professionalism. Burnout is common in clinicians and varying rates have been reported in medical students. No data exist regarding the prevalence of burnout among Israeli medical students. The aims of this study were to assess the rate of burnout in Israeli medical students and to identify students who were particularly susceptible to burnout.

Methods
A cross-sectional questionnaire design was employed, gathering data from medical students in all years of study across three medical schools. Burnout was measured using the Maslach Burnout Inventory Student Survey (MBI-SS), translated into Hebrew.

Results
Of the 2160 students in the participating medical schools, 966 (44.7%) completed MBI-SS and demographic questionnaires. The overall burnout rate was 50.6%. Multivariate logistic regression analysis yielded that female gender, age under 25, advanced year of study, studying at a specific medical school and not being a parent are all significantly correlated with higher levels of burnout.

Conclusions
A high rate of burnout was found. The identification of young women who are not parents during advanced years of studies as being at-risk is important, in order to guide the development of burnout prevention interventions.

Published: January 2023

AbstractBackgroundThe lack of interoperability between health information systems reduces the quality of care provided to patients and wastes resources. Accordingly, there is an urgent need to develop integration mechanisms among the various health information systems. The aim of this review was to investigate the interoperability requirements for heterogeneous health information systems and to summarize and present them.MethodsIn accordance with the PRISMA guideline, a broad electronic search of all literature was conducted on the topic through six databases, including PubMed, Web of science, Scopus, MEDLINE, Cochrane Library and Embase to 25 July 2022. The inclusion criteria were to select English-written articles available in full text with the closest objectives. 36 articles were selected for further analysis.ResultsInteroperability has been raised in the field of health information systems from 2003 and now it is one of the topics of interest to researchers. The projects done in this field are mostly in the national scope and to achieve the electronic health record. HL7 FHIR, CDA, HIPAA and SNOMED-CT, SOA, RIM, XML, API, JAVA and SQL are among the most important requirements for implementing interoperability. In order to guarantee the concept of data exchange, semantic interaction is the best choice because the systems can recognize and process semantically similar information homogeneously.ConclusionsThe health industry has become more complex and has new needs. Interoperability meets this needs by communicating between the output and input of processor systems and making easier to access the data in the required formats.

Published: January 2023

Abstract
Background
Concurrent atherogenic dyslipidemia and elevated inflammation are commonly observed in overt hyperglycemia and have long been proposed to contribute to diabetogenesis. However, the temporal relationship between them and the effect of their cumulative co-exposure on future incident type 2 diabetes (T2D) remains unclear.

Methods
Longitudinal analysis of data on 52,224 participants from a real-world, prospective cohort study (Kailuan Study) was performed to address the temporal relationship between high-sensitivity C-reactive protein (hsCRP) and the atherogenic index of plasma (AIP, calculated as triglyceride/high-density lipoprotein) in an approximately 4-year exposure period (2006/2007 to 2010/2011). After excluding 8824 participants with known diabetes, 43,360 nondiabetic participants were included for further analysis of the T2D outcome. Cox regression models were used to examine the adjusted hazard ratios (aHRs) upon the cumulative hsCRP (CumCRP) and AIP (CumAIP) in the exposure period.

Results
In temporal analysis, the adjusted standardized correlation coefficient (β1) of hsCRP_2006/2007 and AIP_2010/2011 was 0.0740 (95% CI, 0.0659 to 0.0820; P < 0.001), whereas the standardized correlation coefficient (β2) of AIP_2006/2007 and hsCRP_2010/2011 was − 0.0293 (95% CI, − 0.0385 to − 0.0201; P < 0.001), which was significantly less than β1 (P < 0.001). During a median follow-up of 7.9 years, 5,118 T2D cases occurred. Isolated exposure to CumAIP or CumCRP was dose-dependently associated with T2D risks, independent of traditional risk factors. Significant interactions were observed between the median CumAIP (− 0.0701) and CumCRP thresholds (1, 3 mg/L) (P = 0.0308). Compared to CumAIP < − 0.0701 and CumCRP < 1 mg/L, those in the same CumAIP stratum but with increasing CumCRP levels had an approximately 1.5-fold higher T2D risk; those in higher CumAIP stratum had significantly higher aHRs (95% CIs): 1.64 (1.45–1.86), 1.87 (1.68–2.09), and 2.04 (1.81–2.30), respectively, in the CumCRP < 1, 1 ≤ CumCRP < 3, CumCRP ≥ 3 mg/L strata. Additionally, the T2D risks in the co-exposure were more prominent in nonhypertensive, nondyslipidemic, nonprediabetic, or female participants.

Conclusions
These findings suggest a stronger association between elevated hsCRP and future AIP changes than vice versa and highlight the urgent need for combined assessment and management of chronic inflammation and atherogenic dyslipidemia in primary prevention, particularly for those with subclinical risks of T2D.
CCND2 and miR-206 as potential biomarkers in the clinical diagnosis of thyroid carcinoma by fine-needle aspiration cytology
Authors: Yuan Shifa , Liu Zhijun , Yu Shanshan , Wang Xiaolei , Shi Jian 
Published: January 2023

Abstract
Background
To investigate the relationship between cyclin D2 (CCND2) and miR-206 expression in fine-needle aspiration cytology of thyroid carcinoma.

Methods
A total of 65 patients with thyroid carcinoma were selected as the subjects and 65 patients with benign thyroid nodules were in control group. The fine-needle aspiration cytology of thyroid nodules was performed. CCND2 and miR-206 levels were detected by PCR.

Results
Compared with the patients with benign thyroid nodules, the expression level of miR-206 in fine-needle aspiration cytology of thyroid cancer patients decreased significantly and the expression level of CCND2 increased significantly. CCND2 and miR-206 expression was negatively correlated in thyroid cancer tissues. Area under curve (AUC) of miR-206 level in the diagnosis of thyroid cancer was 0.889, and the sensitivity and specificity were 92.3% and 81.5%, respectively. AUC of CCND2 level in the diagnosis of thyroid cancer was 0.837, and the sensitivity and specificity were 67.7% and 89.2%, respectively. The AUC of combined detection of CCND2 and miR-206 in the diagnosis of thyroid cancer was 0.959, and the sensitivity and specificity were 93.8% and 87.7%, respectively. The levels of miR-206 and CCND2 were significantly correlated with TNM staging and lymph node metastasis.

Conclusions
miR-206 and CCND2 may become new biomarkers for clinical diagnosis of thyroid cancer based on the fine-needle aspiration cytology of thyroid nodules.
Integrating case management for patients with complex needs in the ground practice: the importance of context in evaluative designs
Authors: Hudon Catherine , Kessler Rodger 
Published: January 2023

AbstractResponding to complex needs calls for integrating care across providers, settings and sectors. Among models to improve integrated care, case management demonstrates a good evidence base of facilitating the appropriate delivery of healthcare services. Since case management is a complex, multi component intervention, with its component parts interacting in a non-linear manner, effectiveness is largely influenced by the context in which the intervention is implemented. This paper discusses how to respond to implementation challenges to evaluating complex interventions for patients with complex needs. Building on the example of case management, we suggest that documenting innovation effectiveness remains important, but that evaluation needs to include theory-based and systems perspectives. We also suggest that implementation science needs to be part of intervention design while engaging stakeholders to define the most relevant research questions and implementation effectiveness, to optimize successful implementation and sustainability.
In-country availability of medical abortion medicines: a description of the framework and methodology of the WHO landscape assessments
Authors: Rehnström Loi Ulrika , Prata Ndola , Grossman Amy , Lavelanet Antonella , Williams Natalie , Ganatra Bela 
Published: January 2023

Abstract
Background
Availability of quality-assured medical abortion medicines plays a crucial role in providing comprehensive abortion care. However, access to these medicines is still restricted for many abortion seekers. Increasing availability of affordable, quality-assured mifepristone and misoprostol is important to improve access to safe medical abortion services. Driven by the outcomes of a global consultation hosted by the World Health Organization and the Swedish International Development Cooperation Agency in 2018, we decided to holistically examine access to medical abortion medicines from supply to demand. The overarching principle of the national landscape assessments was to generate evidence to support policy dialog and policymaking that is contextual to the needs of the country. This paper aims to describe the framework and methodological approach used in the World Health Organization landscape assessments of medical abortion medicines at country-level.

Methods
A country assessment protocol was developed to guide the methodology of the World Health Organization landscape assessments. The assessment protocol included adaptation of an existing availability framework, an online desk review and literature review for existing data available for the country of interest, country-level key informant interviews, and analysis of the data to identify barriers and opportunities to improve medical abortion availability.

Conclusion
The availability framework and methodology will allow the identification of key barriers that limit readiness of medical abortion medicines, and the development of opportunities to overcome those barriers. The national landscape assessments will provide directions for future investments and offer guidance for policy and programming on medical abortion care.

Abstract
Background
In Brazil, childbirth practices are strongly marked by surgical events and particularly in the private sector cesarean sections reach rates above 80%. The National Supplementary Health Agency proposed the Adequate Childbirth Project (PPA), a quality improvement project developed at Brazilian hospitals with the aim of changing the current model of childbirth care and reducing unnecessary cesarean sections. The objective of this study is to assess how the participation of women in the process of improving quality childbirth care occurred in two hospitals participating in the PPA.

Method
Qualitative study, based on interviews with 102 women attended at two hospitals that took part in the first and second stages of the “Healthy Birth”, an evaluative hospital-based research, conducted in 2017–2018, that assessed the degree of implementation and the effects of PPA. After thematic content analysis, supported by MaxQda software, three categories emerged: (1) how women gathered knowledge about the PPA, (2) how women perceived it, and (3) which are their suggestions for the PPA improvement.

Results
The PPA was unknown to most women before delivery. A polysemy of terms, including adequate childbirth, promotes recognition of the “new” model of care. Visits to the maternity hospital and antenatal care groups for pregnant women are opportunities for contacts that change the perception of what childbirth can be. Women have expectations of a relationship with maternity that is not limited to the moment of delivery. The listening channels established between hospitals and women are fragile and not systematized. By increasing the supply of listening spaces, one can also increase the request to leave their suggestions and contributions, and thus gain more allies in improving the project. Women are not yet included as PPA agents and their voices are silenced.

Conclusions
Women’s participation to improve childbirth care is relevant and necessary. The women’s voice in the PPA is still incipient, and maternity hospitals and health plan operators should create strategies to insert and engage them. Women’s voices should be listened to not only during but also before and after childbirth.
Effect of mobile application types on stroke rehabilitation: a systematic review
Authors: Szeto Stephen G. , Wan Hoyee , Alavinia Mohammad , Dukelow Sean , MacNeill Heather 
Published: January 2023

Abstract
Background
Stroke is a significant contributor of worldwide disability and morbidity with substantial economic consequences. Rehabilitation is a vital component of stroke recovery, but inpatient stroke rehabilitation programs can struggle to meet the recommended hours of therapy per day outlined by the Canadian Stroke Best Practices and American Heart Association. Mobile applications (apps) are an emerging technology which may help bridge this deficit, however this area is understudied. The purpose of this study is to review the effect of mobile apps for stroke rehabilitation on stroke impairments and functional outcomes. Specifically, this paper will delve into the impact of varying mobile app types on stroke rehabilitation.

Methods
This systematic review included 29 studies: 11 randomized control trials and 18 quasi-experimental studies. Data extrapolation mapped 5 mobile app types (therapy apps, education apps, rehab videos, reminders, and a combination of rehab videos with reminders) to stroke deficits (motor paresis, aphasia, neglect), adherence to exercise, activities of daily living (ADLs), quality of life, secondary stroke prevention, and depression and anxiety.

Results
There were multiple studies supporting the use of therapy apps for motor paresis or aphasia, rehab videos for exercise adherence, and reminders for exercise adherence. For permutations involving other app types with stroke deficits or functional outcomes (adherence to exercise, ADLs, quality of life, secondary stroke prevention, depression and anxiety), the results were either non-significant or limited by a paucity of studies.

Conclusion
Mobile apps demonstrate potential to assist with stroke recovery and augment face to face rehabilitation, however, development of a mobile app should be carefully planned when targeting specific stroke deficits or functional outcomes. This study found that mobile app types which mimicked principles of effective face-to-face therapy (massed practice, task-specific practice, goal-oriented practice, multisensory stimulation, rhythmic cueing, feedback, social interaction, and constraint-induced therapy) and education (interactivity, feedback, repetition, practice exercises, social learning) had the greatest benefits.
