Abstract
Background
Toll like receptors (TLR) 2 and 4 present on innate immune cells of the dental pulp detect cariogenic bacteria. Along with bacteria, C. albicans may also be present in dental caries. The presence of C. albicans can be detected by Dectin-1 a C type Lectin receptor. Expression of Dectin-1 in human pulpits has not been reported. Similarly, cytokines are released as a consequence of dental pulp inflammation caused by cariogenic bacteria. The T helper (Th) 1 inflammatory response leads to exacerbation of inflammation and its relationship with Osteopontin (OPN) is not known in pulp inflammation.

Objective
The aim of this study was to observe the expression of Dectin-1, TLR-2, OPN and pro-inflammatory cytokines in irreversibly inflamed human dental pulp and to observe relationship between Dectin-1/TLR-2 and OPN/Pro-inflammatory cytokines in the presence of appropriate controls.

Methods
A total of 28 subjects diagnosed with irreversible pulpitis were included in this ex-vivo study. Fifteen samples were subjected to standard hematoxylin and Eosin (H&E) and immunohistochemistry staining. Whereas, gene expression analysis was performed on 13 samples to observe mRNA expression of pro-inflammatory cytokines; tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1 beta (ß), IL-6 Dectin-1, OPN, TLR-2 and TLR-4. SPSS version 21 was used for statistical analysis. One way analysis of variance (ANOVA), Pearson correlation and Chi-square test were used at p ≤ 0.05.

Results
Gene expressions of Dectin-1, TLR-2 and TLR-4 were observed in all samples. Dectin-1 and TLR-2 expressions were significantly correlated (r = 0.5587, p = 0.0002). Similarly, OPN and TNF-α expression showed a significant correlation (r = 0.5860, p = 0001). The agreement between histologic and clinical diagnosis was 69.2% in the cases of irreversible pulpitis.

Conclusion
Dectin-1 was expressed by inflamed human dental pulp. Dectin-1 and TLR-2 expression pattern was suggestive of a collaborative receptor response in inflamed pulp environment. OPN and TNF-α expressions showed a positive correlation indicating a possible relationship.

Published: December 2022

AbstractBackgroundThis study aimed to compare the efficacy of EndoActivator, passive ultrasonic irrigation, and Ultra X in removing calcium hydroxide from the artificial grooves in root canal walls.MethodsThe root canals of 50 extracted human maxillary incisors were instrumented by using the ProTaper rotary system up to #F4 (size 40/0.06 ProTaper) and the teeth were split longitudinally. Lateral grooves were created in the apical and coronal parts of one half and the middle part of the other half. Calcium hydroxide paste was applied to the grooves and the root halves were reassembled. After seven days, the calcium hydroxide was removed from the canal by using one of the EndoActivator, passive ultrasonic irrigation, and Ultra X devices; one group went without irrigation (control group). The CH remnants in the grooves were scored at 20× magnification. The data were analyzed by using the Kruskal–Wallis, Dunn’s post hoc, and Friedman tests.P < 0.05 was considered to be statistically significant.ResultsNo statistically significant difference existed among the experimental groups at the coronal and middle grooves (P > 0.05). However, Ultra X was significantly more effective than passive ultrasonic irrigation at the apical grooves (P = 0.023).ConclusionWithin the limitations of this study, Ultra X can be reported to remove the calcium hydroxide from the apical third more efficiently than passive ultrasonic irrigation.

Published: December 2022

Abstract
Background
Endometrioid Stromal Sarcomas are an infrequent group of mesenchymal tumors that we must take into account in the differential diagnosis despite representing only 0.2% of tumors of the female genital tract, as they can go unnoticed until advanced stages.

Case presentation
Fifty-fourth year-old woman referred from the Urology department due to incidental finding of adnexal mass in MRI during examination after renoureteral colic, in the case of a 50 mm solid cystic mass in LE. MT were within the normal range, and the CT scan observed this mass in contact with the left ureter. The surgery was completed with hysterectomy and contralateral adnexectomy without incident and chemotherapy treatment was not added. The pathological result was ovarian tissue with low-grade endometrial sarcoma. Currently, after two years of follow-up, the patient remains stable without any recurrence of disease.

Conclusions
Endometrioid stromal sarcomas are rare tumors that originate in the endometrial stroma, the ovarian location being rare. Management lies in surgical treatment, and adjuvant therapy is sometimes necessary in advanced stages.

Published: December 2022

Abstract
Background
Common bile duct ligation (BDL) is a rat experimental model to induce biliary cirrhosis. Lung fibrosis and pulmonary vascular angiogenesis and congestion are the most common complications of biliary cirrhosis that is known as hepatopulmonary syndrome. The aim of the present work is to investigate the acute lung injury in a BDL model and to investigate the possible protective effect of quercetin on this injury.

Methods
Twenty-four adult male albino rats of the Wister strain (weighing 150–250 g). Animals were divided into 3 groups, with 8 rats each: Group I: Sham-operated group (control). Group II: Bile duct ligation group (BDL) sacrificed after 28 days from the surgery. Group III: Quercetin-treated bile duct ligation group (Q-BDL) was given orally by gastric gavage in a dose of 50 mg/kg/day, starting from the 4th day of the operation until the 28th day. At the end of the experiment, at day 28, all rats were sacrificed. Lung specimens were processed to measure Endothelin B receptor gene expression by PCR, lung surfactant by ELISA, “eNO” s by immunohistochemistry. Histological assessment was done using; H&E, Masson’s trichrome, PAS, toluidine blue-stained semi-thin sections, transmission electron microscope. Histomorphometric and statistical studies were done.

Results
BDL group showed significant increase in lung index together with mononuclear cellular infiltration denoting lung inflammatory state. Also, the significant increase in pulmonary endothelial nitric oxide synthase ("eNO" s) area percent and endothelin B receptor (ETB) gene expression indicates enhanced angiogenesis. Pulmonary surfactant concentration was significantly decreased together with thickening of interalveolar septa denoting lung injury and fibrosis. Quercetin led to significant decrease in lung index, pulmonary "eNO" s area percent, ETB gene expression and significant increase in pulmonary surfactant concentration. Quercetin treatment improved histological changes and morphometric measurements, limited mononuclear cellular infiltration and decreased perivascular and perialveolar collagen deposition.

Conclusion
Quercetin ameliorates the hepatopulmonary syndrome-induced lung injury through its anti-inflammatory, antioxidative and antifibrotic effects.
Assessing knowledge of herbal medicine course for dental students
Authors: Natto Zuhair S. 
Published: December 2022

Abstract
Background
The aims of this article are to assess dental students’ knowledge about herbal medicine usage and the potential benefits and side effects, and to conduct a short course about herbal medicine.

Methods
All fourth-year pre-doctoral students were invited to participate in a herbal medicine course as a test while the sixth-year students were the control group. A survey was tested for validity and reliability. It comprised of 16 multiple choice questions was given before the course and one month after the course. The sum score of knowledge for each participant was calcuated based on the ability to identify the use of herbs in dentistry with high-quality evidence (correct answer) or total answer for periodontal disease and caries.

Results
The response rate for completing the study was 112 fourth-year students (73.7%) and 64 sixth-year students (39.0%). More than half of the participants (52.5%) were unsure about the importance of herbal medicine in dentistry. However, the majority also stated that the most common herbs used in dentistry were clove (62.9%), followed by curcuma turmeric (54.7%) and meswak (43.0%). The fourth-year students displayed evidence of a higher overall knowledge score after the course in herbal medicine related to periodontal disease in total and correct answers (mean 4.48 ± 4.13, 3.73 ± 3.31, respectively) compared to before the course (mean 0.84 ± 1.23, 0.74 ± 1.16, respectively) (p-value < 0.001). The post-course periodontal disease total and correct answers were statistically significant between fourth- and sixth-year students.

Conclusion
Herbal medicine has a potential positive impact on dentistry. However, these effects are not fully investigated and received full attention in academic institute. This short educational program related to medicinal herbs can improve the knowledge of dental students. This will help increase the awareness about the use and potential side effects of herbal medicine in the dental field.

Published: December 2022

Abstract
Background
Nurses working in the Intensive Care Unit (ICU), due to the sensitivity and difficulty of tasks, need continuous and scientific training to be able to offer the best performance in difficult situations and use their knowledge in the best way. Also, nursing students spend internships in ICUs and receive special training in practice in the actual center. Educational tools based on new technologies can potentially improve the educational outcomes of nursing in ICUs.

Objectives
The present study aims to review and evaluate the effect of using technology-based educational tools for training critical care nurses and nursing students.

Methods
A comprehensive search was conducted to identify peer-reviewed English language articles in Embase, Medline (through PubMed), Scopus, and ISI web of science published from 2010 to Feb 18, 2022. The studies that examined the effectiveness of technology-based educational interventions with control groups were included. The risk of bias in each study was assessed using the Cochrane Collaboration’s tool. Also, we used Standard Mean Difference (SMD) to estimate the effect of technology-based educational tools on learning outcomes. All meta-analyses were performed with a random effects model in Stata Ver.16.

Results
Altogether, ten studies were eligible for the quality assessment and systematic review, while one study that had not reported the pre-intervention analysis was excluded from the meta-analysis. Nine studies were considered to have a low RoB regarding reporting ways, and one of them showed a high risk. Performance and selection bias caused a high risk in six and five of the studies, respectively. In the meta-analysis, improvement in knowledge (SMD = 0.91), skills (SMD = 0.52), and self-confidence (SMD = 0.96) was noticed by applying technology-based educational tools.

Conclusion
It can be offered that if the learning method based on the new technologies tested is more effective than conventional teaching methods, they are likely to improve the learning outcome significantly. The new-developed tools also have great potential in improving health care functions among nurses or nursing students as well as enhancing the quality of life and patient satisfaction.
Would you consider donating your left-over embryos to treat Parkinson’s disease? Interviews with individuals that underwent IVF in Sweden
Authors: Bywall Karin Schölin , Holte Jan , Brodin Thomas , Hansson Mats , Drevin Jennifer 
Published: December 2022

Abstract
Background
Parkinson’s disease (PD) has been considered to be one of the most promising target diseases for forthcoming cell-based therapy. The aim of this study is to explore the views of individuals with cryopreserved embryos on using human embryonic stem cells for treating PD.

Methods
The study was performed as a qualitative, semi-structured interview study in June–October 2020. Participants were recruited at a private fertility clinic located in one of the larger Swedish cities. The clinic provides both publicly financed and privately financed IVF-treatments. All interviews were performed by telephone and analyzed using thematic content analysis. Five main categories emerged from 27 sub-categories.

Results
In total, 18 interviews were performed with 22 individuals, as either a couple (n = 16) or separately (n = 6). Participants had different views on what a cryopreserved embryo is. Some participants addressed cryopreserved embryos as ‘a lump of cells’, and some in terms of their ‘unborn child’. Conditions for donation of cryopreserved embryos for cell-based treatment in PD were: not losing control of what is happening to the embryo, that donating must be voluntary and based on informed consent with time for reflection, that reimbursement, equality and transparency.

Conclusions
Using cryopreserved embryos to treat PD is associated with fundamental ethical and practical issues. This study shows that IVF couples with left-over embryos may be supportive but there is a need for future research to assess people’s views on using cryopreserved embryos for cell-based treatment in PD on a more aggregated level.

Authors: Haardt Victoire , Cambriel Amélie , Hubert Sidonie , Tran Marc , Bruel Cédric , Philippart Francois ,   for the REQUIEM Study group
Published: December 2022

Abstract
Background
The ageing of the population and the increased number of chronic diseases are associated with an increased frequency of end of life care in hospital settings. Residents rotating in hospital wards play a major part in their care, regardless of their specialty. General practitioner (GP) residents are confronted to such activities in hospital settings during their training. Our aim was to know how they feel about taking care of dying patients, as end-of-life care are very different from the clinical activity they are trained to.

Methods
We surveyed all GP trainees of “Ile de France”. The survey was made of 41 questions regarding advanced directives divided in 7 sections about patients’ care, communication, mentoring and repercussion on personal life. The survey was done one time, during two pre-specified days.

Results
525 residents (53.8%) accepted to fulfill the survey. 74.1% of the residents thought that palliative care could have been better. Possible ways of improvements were: a reduction of unreasonable obstinacy (or therapeutic overkill, two terms defined in French law as curative treatment without reasonable hope of efficiency) (59.6%), patient’s (210 answers, 40%) and relative’s communication (information of patients and relatives about the severity of the disease and risk of death) (199 answers 37.9%). Residents also reported a lack of knowledge regarding end-of-life care specific treatments (411 answers, 79.3%) and 298 (47.2%) wished for better mentoring. Those difficulties were associated with repercussion on their private life (353 answers, 67.2%), particularly with their close relatives (55.4%). Finally, 56.2% of trainees thought that a systematic psychologic follow up should be instituted for those working in “at risk” hospital settings.

Conclusion
Self-perception management of dying patients by GP resident emphasize their lack of training and supervision. The feeling of suboptimal care is associated with consequences on personal life.
Neural-signature methods for structured EHR prediction
Authors: Vauvelle Andre , Creed Paidi , Denaxas Spiros 
Published: December 2022

AbstractModels that can effectively represent structured Electronic Healthcare Records (EHR) are central to an increasing range of applications in healthcare. Due to the sequential nature of health data, Recurrent Neural Networks have emerged as the dominant component within state-of-the-art architectures. The signature transform represents an alternative modelling paradigm for sequential data. This transform provides a non-learnt approach to creating a fixed vector representation of temporal features and has shown strong performances across an increasing number of domains, including medical data. However, the signature method has not yet been applied to structured EHR data. To this end, we follow recent work that enables the signature to be used as a differentiable layer within a neural architecture enabling application in high dimensional domains where calculation would have previously been intractable. Using a heart failure prediction task as an exemplar, we provide an empirical evaluation of different variations of the signature method and compare against state-of-the-art baselines. This first application of neural-signature methods in real-world healthcare data shows a competitive performance when compared to strong baselines and thus warrants further investigation within the health domain.

Abstract
Background
Private health care facilities working in partnership with the public health sector is one option to create sustainable health systems and ensure health and well-being for all in low-income countries. As the second-most populous country in Africa with a rapidly growing economy, demand for health services in Ethiopia is increasing and one-quarter of its health facilities are privately owned. The Private Health Sector Program (PHSP), funded by the United States Agency for International Development, implemented a series of public–private partnership in health projects from 2004 to 2020 to address several public health priorities, including tuberculosis, malaria, HIV/AIDS, and family planning. We assessed PHSP’s performance in leadership and governance, access to medicines, health management information systems, human resources, service provision, and finance.

Methods
The World Health Organization’s health systems strengthening framework, which is organized around six health system building blocks, guided the assessment. We conducted 50 key informant interviews and a health facility assessment at 106 private health facilities supported by the PHSP to evaluate its performance.

Results
All six building blocks were addressed by the program and key informants shared that several policy and strategic changes were conducive to supporting the functioning of private health facilities. The provision of free medicines from the public pharmaceutical logistics system, relaxation of strict regulatory policies that restricted service provision through the private sector, training of private providers, and public–private mix guidelines developed for tuberculosis, malaria, and reproductive, maternal, newborn, child, and adolescent health helped increase the use of services at health facilities.

Conclusions
Some challenges and threats to sustainability remain, including fragile partnerships between public and private bodies, resource constraints, mistrust between the public and private sectors, limited incentives for the private sector, and oversight of the quality of services. To continue with gains in the policy environment, service accessibility, and other aspects of the health system, the government and international communities must work collaboratively to address public–private partnerships in health areas that can be strengthened. Future efforts should emphasize a mechanism to ensure that the private sector is capable, incentivized, and supervised to deliver continuous, high-quality and equitable services.

Published: December 2022

AbstractBackgroundIn attempt to improve continuity of patient care and reduce length of stay, hospitals have placed an increased focus on reducing delayed discharges through discharge planning. Several benefits and challenges to team-based approaches for discharge planning have been identified. Despite this, professional hierarchies and power dynamics are common challenges experienced by healthcare providers who are trying to work as a team when dealing with delayed discharges. The objective of this study was to explore what was working well with formal care team-based discharge processes, as well as challenges experienced, in order to outline how teams can function to better support transitions for patients experiencing a delayed discharge. MethodsWe conducted a descriptive qualitative study with hospital-based healthcare providers, managers and organizational leaders who had experience with delayed discharges. Participants were recruited from two diverse health regions in Ontario, Canada. In-depth, semi-structured interviews were conducted in-person, by telephone or teleconference between December 2019 and October 2020. All interviews were recorded and transcribed. A codebook was developed by the research team and applied to all transcripts. Data were analyzed inductively, as well as deductively through directed content analysis.ResultsWe organized our findings into three main categories – (1) collaboration with physicians makes a difference; (2) leadership should meaningfully engage with frontline providers and (3) partnerships across sectors are critical. Regular physician engagement, as equal members of the team, was recommended to improve consistent communication, relationship building between providers, accessibility, and in-person communication. Participants highlighted the need for a dedicated senior leader who ensured members of the team were treated as equals and advocated for the team. Improved partnerships across sectors included the enhanced integration of community-based providers into discharge planning by placing more focus on collaborative practice, combined discharge planning meetings, and having embedded and physically accessible care coordinators in the hospital.ConclusionsTeam-based approaches for delayed discharge can offer benefits. However, to optimize how teams function in supporting these processes, it is important to consistently collaborate with physicians, ensure senior leadership engage with and seek feedback from frontline providers through co-design, and actively integrate the community sector in discharge planning.
