Published: March 2024

Abstract
Background
With increasing studies being published on regenerative endodontic procedures (REPs) as a treatment modality for mature necrotic teeth, the assessment of outcomes following regenerative endodontic procedures has become more challenging and the demand for a better understanding of the regenerated tissues following this treatment is rising. The study aimed to correlate cold, electric pulp testing (EPT), and magnetic resonance imaging (MRI) signal intensity (SI) in mature necrotic teeth treated with regenerative endodontic procedures.

Methodology
This retrospective cohort study included eighteen adult patients who experienced tooth necrosis in mature maxillary anterior teeth recruited from the outpatient clinic, Conservative Dentistry Department, Faculty of Dentistry, Alexandria University, Alexandria, Egypt from July 2017 until December 2018 with 12 months of follow-up. regenerative endodontic procedures via blood clot were performed. The canals were instrumented by ProTaper Next (PTN) files until final sizes X3 or X5. Biodentine was used as cervical plug material. Pre and post-operative clinical follow-up was done where the patients’ responses to cold and electric pulp testing were given a scoring system and were compared to the normal contralateral tooth. Pre and post-operative magnetic resonance imaging signal intensity of both the involved tooth and its contralateral at the middle and the apical thirds of the root canals were assessed after 3, 6, and 12 months. Data was analyzed using the ANOVA, Friedman and Bonferroni tests. Significance was set at a p-value < 0.05.

Results
All 18 teeth scored a baseline score of “2” for cold and electric pulp testing. There was a significant difference between scores of the cold test at baseline and 12-month follow-up (p < 0.001). There was a significant difference between scores of the electric pulp testing of baseline and 12-month follow-up (p < 0.001). There was a moderately significant indirect (inverse) correlation between magnetic resonance imaging signal intensity and cold test in both the middle and apical thirds at 12 months. No significant correlations were detected between magnetic resonance imaging signal intensity and electric pulp testingat any of the time intervals (p > 0.05).

Conclusion
Magnetic resonance imaging is a successful non-invasive method to assess outcomes of regenerative endodontic procedures and correlating it with another reliable method of assessing pulpal responses, cold test, could validate these outcomes.

Clinical trial registration
The study was registered with ClinicalTrials.gov (ID: NCT03804450).
Perceived communication efficacy and unmet needs for chemotherapy-associated symptom management in patients with lung and colorectal cancer: a cross-sectional study
Authors: Zeng Kai , Zhong Yaping , Chen Xiaofang , Zhang Lili 
Published: March 2024

Abstract
Background
Understanding cancer patients’ unmet needs for chemotherapy-related symptom management will assist clinicians in developing tailored intervention programs. Little is known about the association between perceived communication efficacy and unmet care needs for symptom management in patients with lung and colorectal cancer.

Objectives
To examine the unmet care needs for symptom management of patients with lung and colorectal cancer and their association with perceived communication efficacy.

Methods
A cross-sectional survey was conducted in a tertiary hospital in China from July to November 2020. A convenience sample of 203 patients with lung and colorectal cancer undergoing chemotherapy completed survey questionnaires, including the MD Anderson Symptom Inventory Scale and the Perceived Efficacy in Patient‒Physician Interactions Scale.

Results
Approximately 43% of participants had at least one symptom with unmet needs. Fatigue was reported as the symptom with the highest occurrence (66%), the highest demand for supportive care (36%), and the highest prevalence of unmet needs (19%). Low levels of perceived communication efficacy independently predicted participants’ unmet needs for symptom management (β=-0.13, p = 0.011).

Conclusions
This study highlights the necessity of introducing clinical assessment tools and guidelines to address fatigue and other chemotherapy-induced symptoms in patients with lung and colorectal cancer. Clinical programs designed to actively engage cancer patients to voice their needs and strengthen their communication efficacy are also warranted.

Authors: Granero-Molina José , Jiménez-Lasserrotte María del Mar , Arias Hoyos Cristina , Sánchez María José Torrente , Fernández-Sola Cayetano , Ruiz-Fernández María Dolores 
Published: March 2024

Abstract
Background
Morbid Obesity (MO) is a public health problem that affects a person’s physical, psychological and sexual well-being. Women with MO are affected by their body image and self-concept, and obesity stigma may affect women in social and sexual relationships.

Objective
To describe and understand the experiences of morbidly obese heterosexual women (who are sexually attracted to men) in relation to their body image and sexuality after bariatric surgery.

Methodology
Qualitative study using Merleau-Ponty’s hermeneutic phenomenology as a philosophical framework. Data collection took place between 2020 and 2021 in a southern Spanish province. A total of 22 in-depth interviews were conducted using open-ended questions until data saturation was reached.

Results
Two main themes were identified: (1) “Escaping from a cruel environment”: weight loss to increase self-esteem; with the sub-themes: ‘I love myself now’, and ‘Body image and social relationships; a vicious circle; (2) “Now, I am truly me”: accepting my body to reclaim my sexuality, with the sub-themes: ‘The body as the focal point of sexuality’, and ‘When regaining your sex drive reignites your sex life and relationship’.

Conclusion
Weight loss and body acceptance radically change morbidly obese women’s sex lives after bariatric surgery. They rediscover their bodies, have increased self-esteem, and see improvements in their social relationships and sexuality. These women feel seen, loved and desired, and now value their body image and femininity. As they go through continuous improvements following bariatric surgery, they gradually regain self-esteem, acceptance of their bodies and control over their sex life. Even though the women’s partners benefit from these improvements, they seem to be afraid of being left.

Published: March 2024

Abstract
Background
COVID-19 is a challenge to education systems worldwide. The aim of the study was to explore the impact of COVID-19-pandemic-related emotions and COVID-19-related concern for education on the study careers and professional futures of nursing students.

Methods
The study was completed between March and June 2023 using a multi-stage sampling design. A total of 1126 nursing students were recruited to complete the questionnaire. The self-administered questionnaire consisted of basic characteristics of the subjects, the COVID-19-pandemic-related emotions scale, the COVID-19-related concern for education scale, and the impact of the COVID-19 on study careers and professional futures scale (SCPFI-19 S). One-way ANOVA/t-test, correlation coefficient analysis, and hierarchical linear regression analysis were used to explore factors influencing changes in study careers and professional futures, and the relationship between COVID-19-pandemic-related emotions and COVID-19-related concern for education.

Results
Univariate analysis of variance indicated that residence, willingness, and whether to engage in nursing after graduation were related to SCPFI-19 S (P < 0.05). COVID-19-pandemic-related emotions and COVID-19-related concern for education were significantly and positively associated with SCPFI-19 S (r = 0.566, P < 0.01; r = 0.199, P < 0.01). Stratified multiple regression analysis showed that COVID-19-pandemic-related emotions and COVID-19-related concern for education of nursing students were significant predictors of SCPFI-19 S.

Conclusion
Overall, both COVID-19-pandemic-related emotions and COVID-19-related concern for education were significantly correlated with SCPFI-19 S. In future interventions, schools should consider structures and strategies to support students’ mental health and educational trajectories during current and future epidemics or similar crises.
Comprehension of informed consent and voluntary participation in registration cohorts for phase IIb HIV vaccine trial in Dar Es Salaam, Tanzania: a qualitative descriptive study
Authors: Iseselo Masunga K. , Tarimo Edith A. M. 
Published: March 2024

AbstractBackgroundInformed consent as stipulated in regulatory human research guidelines requires volunteers to be well-informed about what will happen to them in a trial. However, researchers may be faced with the challenge of how to ensure that a volunteer agreeing to take part in a clinical trial is truly informed. This study aimed to find out volunteers’ comprehension of informed consent and voluntary participation in Human Immunodeficiency Virus (HIV) clinical trials during the registration cohort.MethodsWe conducted a qualitative study among volunteers who were enrolled in the registration cohort of HIV clinical trials in Dar es Salaam, Tanzania. A purposive sampling strategy was used to obtain twenty study participants. The data were collected between June and September 2020 using a semi-structured interview guide. In-depth interviews were used to collect the data to obtain deep insights of the individual study participants on the comprehension of informed consent and participation in the clinical trial. A thematic analysis approach was used to analyze the data. Themes and subthemes were supported by the quotes from the participants.ResultsVolunteers described comprehension of informed consent from different perspectives. They reported that various components of the informed consent such as study procedure, confidentiality, risk and benefits were grasped during engagement meetings. Furthermore, the volunteers’ decision to participate in the registration cohort was voluntary. However, trial aspects such as health insurance, free condoms, and medical checkups could have indirectly influenced their reluctance to withdraw from the study.ConclusionEngagement meetings may increase the comprehension of informed consent among potential participants for HIV clinical trials. However, trial incentives may influence participation, and thus future research should focus on the challenges of giving incentives in the study. This will ensure comprehension and voluntary participation in the context of HIV clinical trials.

Published: March 2024

Abstract
Background
Quality healthcare delivery is contingent upon effective teamwork and a patient safety-focused culture. TeamSTEPPS offers an evidence-based framework that enhances these competencies. However, the impact of TeamSTEPPS on newly graduated nurses, who undergo a significant transitional phase, has yet to be comprehensively explored. Consequently, the objective of this study was to assess the influence of TeamSTEPPS on perceptions of teamwork and patient safety culture among newly graduated nurses.

Methods
This study employed a quasi-experimental pretest-posttest design with a single group, utilizing a convenience sample of 132 newly recruited nurses from a university hospital. The participants completed the hospital survey on patient safety culture and the TeamSTEPPS teamwork perceptions questionnaire at three different time points.

Results
The impact of the TeamSTEPPS training program was found to be significant, as indicated by the substantial improvement in the mean scores of nurses’ perceptions regarding teamwork and the culture of patient safety across multiple assessments (p < 0.001). The effect size (η2p ≥ 0.14) suggests a large effect, further emphasizing the meaningful impact of the program on the measured outcomes.

Conclusions
The study underscores the effectiveness of TeamSTEPPS as a valuable framework for facilitating the seamless transition of newly graduated nurses into the healthcare field. Integrating TeamSTEPPS into nursing training programs can significantly enhance nurses’ perceptions of teamwork and the culture of patient safety. Therefore, it is crucial for nurse managers to implement TeamSTEPPS systematically, aiming to improve teamwork perception and cultivate a patient safety culture among nurses. Furthermore, they should establish mechanisms to ensure the consistent application of these skills over time.
Patient’s and healthcare provider’s experiences with Opioid Maintenance Treatment (OMT): a qualitative evidence synthesis
Authors: Steiro Asbjørn , Hestevik Christine Hillestad , Muller Ashley Elizabeth 
Published: March 2024

Abstract
Background
Opioid Maintenance Treatment (OMT) is the gold standard for people with opioid dependence. However, drop-out rates are high, and many patients do not reach desired outcomes. Understanding patients’ and healthcare providers’ experiences with the treatment can provide valuable information to improve the quality of OMT and to increase acceptability and accessibility of services. The aim of this systematic review is to explore and synthesise the experiences of OMT among persons with opioid dependence and health care providers, to inform policy makers and practitioners on how to improve OMT outcomes.

Methods
We conducted a qualitative evidence synthesis. We systematically searched in electronic databases (CINAHL, Embase, MEDLINE, and nordic databases) and searched for grey literature. As we identified many studies that met our inclusion criteria, we purposively sampled a manageable number of studies to include in this review. Two researchers independently extracted and coded data from the included studies and used the Andersen’s healthcare utilization model to organize and develop codes. We assessed the methodological limitations of the studies, and our confidence in the findings using GRADE CERQual.

Results
We retrieved 56 relevant studies and purposively sampled 24 qualitative studies of patients’ and healthcare providers’ experiences with OMT. Our analyses resulted in six main themes: (1) External stigma prevents engagement and retention in treatment, (2) Being identified as in OMT contributed to an increased experience of stigma (3) Inadequate knowledge and expertise among healthcare providers affected patients’ treatment experiences, (4) Quality of communication between personnel and patients impacts patients’ engagement with treatment and treatment outcomes, (5) Patients wanted help with many aspects of their lives not just medication, and (6) Balancing positive expectations of OMT with treatment stigma. We found that stigma was an overarching theme across these themes.

Conclusion
Our findings suggest that OMT could be more beneficial for patients if treatment programs prioritize efforts to diminish societal and OMT provider stigma and find strategies to better address patient needs. Initiatives should focus on improving treatment knowledge among providers, encouraging the use of client perspectives, considering the context of family members, and establishing a more holistic and flexible treatment environment.
Unveiling spatial disparities in basic medical and health services: insights from China’s provincial analysis
Authors: Hou Dainan , Wang Xin 
Published: March 2024

AbstractBased on the panel data of 31 provinces (municipalities and autonomous regions) in China from 2012 to 2019, this paper constructs the evaluation index system of basic medical and health services in China from seven dimensions: medical and health facilities, health expenditure, medical services, traditional Chinese medicine hospital services, maternal and child health care, people’s health and medical security, disease control and public health. The entropy method was used to measure the level of basic medical and health services in China, and its spatial differences and convergence characteristics were further investigated. In this study, we employ the entropy weight method, σ convergence, and β convergence as our primary methodologies. The entropy weight method is used to evaluate the variability of each indicator, determine the weights of indicators, and quantify the information content of the data. σ convergence illustrates the process by which the variance of a sample decreases over time. β convergence refers to the gradual approach of variables within an economic system towards their long-term equilibrium level over time. The results show that: (1) The scores of basic medical and health services in China’s four major regions (including Northeast, East, Central and West) remain in a relatively stable state, with small fluctuations and great room for improvement; (2) There are significant regional differences in the level of basic medical and health services in China, and the intra-regional differences are much greater than the inter-regional differences; (3) There is no significant σ convergence observed in China and its four major regions; however, there is a notable presence of β convergence.
Quality improvement in public–private partnerships in low- and middle-income countries: a systematic review
Authors: Iroz Cassandra B. , Ramaswamy Rohit , Bhutta Zulfiqar A. , Barach Paul 
Published: March 2024

Abstract
Background
Public–private partnerships (PPP) are often how health improvement programs are implemented in low-and-middle-income countries (LMICs). We therefore aimed to systematically review the literature about the aim and impacts of quality improvement (QI) approaches in PPP in LMICs.

Methods
We searched SCOPUS and grey literature for studies published before March 2022. One reviewer screened abstracts and full-text studies for inclusion. The study characteristics, setting, design, outcomes, and lessons learned were abstracted using a standard tool and reviewed in detail by a second author.

Results
We identified 9,457 citations, of which 144 met the inclusion criteria and underwent full-text abstraction. We identified five key themes for successful QI projects in LMICs: 1) leadership support and alignment with overarching priorities, 2) local ownership and engagement of frontline teams, 3) shared authentic learning across teams, 4) resilience in managing external challenges, and 5) robust data and data visualization to track progress. We found great heterogeneity in QI tools, study designs, participants, and outcome measures. Most studies had diffuse aims and poor descriptions of the intervention components and their follow-up. Few papers formally reported on actual deployment of private-sector capital, and either provided insufficient information or did not follow the formal PPP model, which involves capital investment for a explicit return on investment. Few studies discussed the response to their findings and the organizational willingness to change.

Conclusions
Many of the same factors that impact the success of QI in healthcare in high-income countries are relevant for PPP in LMICs. Vague descriptions of the structure and financial arrangements of the PPPs, and the roles of public and private entities made it difficult to draw meaningful conclusions about the impacts of the organizational governance on the outcomes of QI programs in LMICs. While we found many articles in the published literature on PPP-funded QI partnerships in LMICs, there is a dire need for research that more clearly describes the intervention details, implementation challenges, contextual factors, leadership and organizational structures. These details are needed to better align incentives to support the kinds of collaboration needed for guiding accountability in advancing global health. More ownership and power needs to be shifted to local leaders and researchers to improve research equity and sustainability.

Published: March 2024

Abstract
Background
Diffusion-weighted magnetic resonance imaging (DWI) provides a measurement of tumor cellularity. We evaluated the potential of apparent diffusion coefficient (ADC) values obtained from post-external beam radiation therapy (EBRT) DWI and prior to brachytherapy (BT) to predict for complete metabolic response (CMR) in bulky cervical cancer.

Methods
Clinical and DWI (b value = 500 s/mm2) data were obtained from patients undergoing interstitial BT with high-risk clinical target volumes (HR-CTVs) > 30 cc. Volumes were contoured on co-registered T2 weighted images and 90th percentile ADC values were calculated. Patients were stratified by CMR (defined by PET-CT at three months post-BT). Relation of CMR with 90th percentile ADC values and other clinical factors (International Federation of Gynecology and Obstetrics (FIGO) stage, histology, tumor and HR-CTV size, pre-treatment hemoglobin, and age) was assessed both in univariate and multivariate logistic regression analyses. Youden’s J statistic was used to identify a threshold value.

Results
Among 45 patients, twenty-eight (62%) achieved a CMR. On univariate analysis for CMR, only 90th percentile ADC value was significant (p = 0.029) while other imaging and clinical factors were not. Borderline significant factors were HR-CTV size (p = 0.054) and number of chemotherapy cycles (p = 0.078). On multivariate analysis 90th percentile ADC (p < 0.0001) and HR-CTV size (p < 0.003) were highly significant. Patients with 90th percentile ADC values above 2.10 × 10− 3 mm2/s were 5.33 (95% CI, 1.35–24.4) times more likely to achieve CMR.

Conclusions
Clinical DWI may serve to risk-stratify patients undergoing interstitial BT for bulky cervical cancer.
