Titanium implant osseointegration in rheumatoid arthritis patients: Two case reports

Case Implant rehabilitation in patients suffering from rheumatoid arthritis (RA) has been reported an improvement in the quality of life. Implanttreatment success depends on many factors like achievement of appropriate osseointegration. There are many controversies about theinteractions between anti-rheumatic drugs and osseointegration. Moreover, the scientific evidence regarding implant survival in RApatients are scarce. This study presents two case reports including 65- and 51-year-old women who have used low-dose methotrexate andother anti-rheumatic drugs treated by dental implants. After 4-years follow-up, the patients are satisfied of function and aesthetics. Stablebone level was seen around all implants radiographically. Because of the lack of agreement in implant treatment protocol in RA patient,more studies are suggested

The Relationship between Organizational Justice Perception and Self- efficacy in Staff of a Selected Educational Hospital: a case study

Background & Objectives: Hospitals are one of the important components in a health care system and have significant role in health of humans. Organizational justice shows the perception of fairness and equality in the workplace by staff and affects their behavior. This study examines the relationship between organizational justice perception and self-efficacy in employees of a selected hospital of Tabriz/ Iran. Methods: This was a cross-sectional descriptive- analytic study performed on 156 employees of one of the selected hospitals of Tabriz University of Medical Sciences. Chen, Gully & Eden Self-efficacy questionnaire and Rego and Cunha organizational justice questionnaire were used as data collection tools. Data analysis was done through SPSS23 and using analytic statistical tests such as Spearman correlation, Chi-Square and regression. Results: There was a significant positive relationship between dimensions of organizational justice and self- efficacy (P<0.01). Also, based on the results of regression analysis, information justice was a stronger predictor of self- efficacy. Eventually, the elements of procedural, interactions and information justice could predict 14% of variations of self- efficacy. Conclusion: Since dimensions of organizational justice affect employees' self- efficacy, hospital managers should find appropriate strategies for improving organizational justice in order to increase self- efficacy and ultimately the performance of their employees.

Fertility outcomes subsequent to medical and surgical treatment for ectopic pregnancy: A retrospective cohort study in Iran

Background: Ectopic pregnancy (EP) and its treatment methods may affect subsequent fertility outcomes. Objective: To compare methotrexate (MTX), laparoscopic salpingostomy, and salpingectomy methods of EP treatment and their effects on fertility outcomes. Materials and Methods: This retrospective cohort study was performed on women receiving a definitive diagnosis of tubular EP from 2014 to 2017 at Arash Medical Center, Tehran, Iran. In total, 194 women were studied, of which 64 were treated with MTX, 52 underwent salpingostomy, and 78 underwent salpingectomy, depending on their clinical status. Basic information, obstetrics history, and major outcomes of the treatment after an 18-month follow-up, including recurrence of EP, miscarriage, and successful intrauterine pregnancy (IUP), were recorded and variables were compared among the three groups. Results: There was no significant difference in fertility outcomes among the three groups. Among the studied variables, predictors of successful IUP after EP treatment were multiparity (Hazard Ratio (HR): 1.37; 95%CI: 1.06-1.77), no history of miscarriage (HR: 2.37; 95%CI: 1.01-5.56), and a higher number of live births (HR: 1.54; 95%CI: 1.01- 2.37). On the other hand, predictors of EP recurrence included nulliparity (HR: 1.61; 95%CI: 1.02-2.53) and a lower number of live births (HR: 3.84; 95%CI: 1.43-10.98). The effect of other factors, including the utilized therapeutic modalities, was not statistically significant. Conclusion: The current study results demonstrated that after an 18-month follow-up, fertility outcomes, including recurrence of EP and successful IUP, were not significantly different among the subjects with EP treated with MTX, salpingostomy, or salpingectomy. Further studies with long-term follow-ups are recommended. Key words: Ectopic pregnancy, Fertility, Methotrexate, Salpingostomy, Salpingectomy

Expert perspectives on the active role of patients in their safety: Toward a framework using Delphi methodology

Aims: To develop a framework for Patient Engagement in Patient Safety (PEPS) in hospital. Methods: The Delphi technique was embraced to involve a group of knowledgeable healthcare experts in the discussion and rating of the components of the PEPS framework. On a 5‐point Likert scale, every item was separately rated based on the three aspects, which include applicability, clarity and validity. The PEPS framework included items with 75% or more of participants scoring 4–5 on all three aspects. Items not attaining 75% agreement on the aspects were either changed or discarded, after the group discussion and underwent another round of rerating. Results: A total of 17 members participated in the consensus‐building process. Following two rounds of rating, the consensus was reached on the final framework which consisted of 28 items in four dimensions, relating to healthcare professionals, patients, community, and helth system, and three components substituted with patient empowerment, effective communication and patient‐centeredness. Conclusion: The development of PEPS framework is a stimulus to strengthen human resources for health capabilities, sustain a high level of quality patient outcomes, and improve the health system. Further studies to identify strategies are needed for the successful implementation of this framework

Patient and Health Professional Perspectives about Engaging Patients in Addressing Patient Safety: A Systematic Review Protocol

BACKGROUND: Patient safety is crucial to the provision of quality healthcare and has become increasingly important with the world health organisation recognising the significance of patient engagement in safety issues. Despite an increasing amount of literature examining the engagement of patients in addressing their safety, there has been little research examining the perspectives of patients and health professionals regarding the engagement of patients in safety issues. AIM: This protocol aimed to explore the perspectives of patients and health professionals regarding the engagement of patients in safety issues. METHODS: During February 2019, a literature search was conducted using four databases, PubMed/MEDLINE, Embase, Web of Science and Scopus. There were no limits on the year of publication. Two authors were screening the titles, abstracts and full texts of all the studies independently of each other and potential discrepancies will be resolved in consultation with the third author. Studies identified in the literature search were assessed using the Mixed Methods Appraisal Tool (MMAT), and a ‘best fit’ framework synthesis approach was adopted to combine evidence from studies that have used qualitative and mixed methods. CONCLUSION: The results from this study can be used to develop interventions to increase patient engagement with patient safety

Removal of Direct red 12B Dye in an Integrated Fixed Film Activated Sludge Reactor (IFAS): Performance Evaluation and Kinetics Study

The application of biological treatment has been promising in recent years for the main advantage of biological treatment in COD and dye removal. The novelty of this study is capabilities of integrated fixed film system (IFAS) with a different arrangement of media to removal the dye and COD. The experiments were done with a survey of variables like SRT, MLSS/MLVSS, the initial concentration of dye and COD. In order to analyze data was used the first and second-order models. The result showed that the IFAS was effective even at high concentration of the dye (200mg L-1). COD reduction and dye removal efficiency were higher than 70% and 88-95%, respectively. For the biological treatment, an increase in SRT to 48hr. increased the dye and COD concentration reduction. Kinetics of COD reduction and dye removal was fitted with the second-order reaction by coefficient correlation of 0.95 and 0.97, respectively. Finally, the integration of fixed film media into the biological reactors affected performances of the system for decolorization from colored wastewater

Comparison study of COD adsorption on bentonite-based nanocomposite materials in landfill leachate treatment: Characterization, Isotherms, Kinetics and Regeneration

The COD removal from landfill leachate using bentonite-based nanocomposites prepared using different modifiers has been investigated. Different techniques including FE-SEM, XRD, FTIR, TGA and Zeta potential have been utilized for characterization of nanocomposites (NCs). The independent variables includingNCs dose, pH and contact time are studied for COD removal efficiency. The optimal values are obtained to be a NCs dose of 40 g/L, pH of 3.00, and a contact time of 20 min for maximized COD removal efficiencies of 67.90, 71.30 and 52.00% using Arg/CTS-BEN, H/CTS-BEN and CTSBEN NCs, respectively. Kinetics studies fitted well with the pseudo-second order model with rate constants of 25.64, 28.65 and 25.00 mg/g by H/CTS-BEN, Arg/CTS-BEN and CTS-BEN NCs, respectively. The adsorption of the COD is well described by Langmuir equations (R2 0.99). Results show that the synthesized NCs is promising and efficient in purifying landfill leachate

Experiences of critical care nurses fighting againstCOVID‐19: A qualitative phenomenological study

Aim: This study sought to describe the experiences of critical care nurses caring for patients infected by coronavirus disease 2019 (COVID‐19). Design: A qualitative phenomenological design was used. Methods: We enrolled 15 nurses who provided care for patients infected by COVID‐19 purposively and through snowballing, using a phenomenological approach in critical care units of Iran's public hospitals between May and June 2020. The semi‐structured interviews were carried out either via face‐to‐face or telephone and were analyzed using the 7‐step method of Colaizzi. Results: The experiences of nurses caring for patients infected with COVID‐19 were categorized into four challenges, including psychological (eight subthemes), organizational (six subthemes), social (six subthemes), and professional (five subthemes). In general, based on the current classification, there seems to be a mixture of positive and negative effects on the psychological, social, and professional challenges and the negative effect only on the organizational challenges. Conclusions: Positive and negative emotions and experiences have coexisted for the critical care nurses since the COVID‐19 outbreak. Emotional support and psychological counseling play an important role in maintaining nurses' optimal mental health during the COVID‐19 crisis. Adequate protective equipment, financial and nonfinancial supports, effective communication, training and hiring of staff, and appropriate work shifts are also required to reduce nurses' negative experiences when providing care for the affected individuals

Inhibitory effect of natural compounds on quorum sensing system in Pseudomonas aeruginosa: a helpful promise for managing biofilm community

Pseudomonas aeruginosa biofilm is a community of bacteria that adhere to live or non-living surfaces and are encapsulated by an extracellular polymeric substance. Unlike individual planktonic cells, biofilms possess a notable inherent resistance to sanitizers and antibiotics. Overcoming this resistance is a substantial barrier in the medical and food industries. Hence, while antibiotics are ineffective in eradicating P. aeruginosa biofilm, scientists have explored alternate strategies, including the utilization of natural compounds as a novel treatment option. To this end, curcumin, carvacrol, thymol, eugenol, cinnamaldehyde, coumarin, catechin, terpinene-4-ol, linalool, pinene, linoleic acid, saponin, and geraniol are the major natural compounds extensively utilized for the management of the P. aeruginosa biofilm community. Noteworthy, the exact interaction of natural compounds and the biofilm of this bacterium is not elucidated yet; however, the interference with the quorum sensing system and the inhibition of autoinducer production in P. aeruginosa are the main possible mechanisms. Noteworthy, the use of different drug platforms can overcome some drawbacks of natural compounds, such as insolubility in water, limited oral bioavailability, fast metabolism, and degradation. Additionally, drug platforms can deliver different antibiofilm agents simultaneously, which enhances the antibiofilm potential of natural compounds. This article explores many facets of utilizing natural compounds to inhibit and eradicate P. aeruginosa biofilms. It also examines the techniques and protocols employed to enhance the effectiveness of these compounds
