Background Advertising is one of the most important solutions that health centers and medical services around the world use to try to encourage public opinion to create a positive attitude towards preventive measures and vaccination. This study has been done with the aim of text analysis of billboards and infographics related to promoting preventive behaviors and vaccination against the coronavirus pandemic and providing solutions and models for preventive information and advertising in the field of health. Methods The study method in this research is a combination of qualitative and content analysis. Data collection was done in a targeted manner. The sample size includes 33 advertising billboards and infographics. Data collection has been done through searching the sites and websites of health networks and medical education centers in Iran, taking pictures of infographics and billboards in public places, and also receiving archive files of pictures from the public relations of health networks and medical services. The data was collected from February 19, 2020 to December 30, 2022 (the time frame of the pandemic and public vaccination program in Iran). The data was analyzed based on the three-dimensional discourse analysis theory of Fairclough. Then, an online survey about promoting preventive behaviors and vaccination against the coronavirus pandemic in the format of billboards and infographics was designed in SurveyMonkey and its link was provided to the audience through virtual networks and other platforms. The age group of people was selected from 18 to 70 years. Considering that the number of participants should be representative of the entire community under investigation, therefore, based on Cochran’s formula, the sample size was equal to 350 people. Finally, users’ opinions were analyzed using descriptive statistics. The assessment of validity involved experts in infection control and linguistics. The reliability of the measurement, determined through the Cronbach’s alpha internal consistency coefficient, yielded a coefficient of 0.968. Results The results show that among the four linguistic components of words, syntax, coherence and text structure; “live metaphors”, “pronoun “we”, “collocation and reference”, and “attitude markers” have the most impact on the audience. The frequency percentage of the data shows that these language elements have tremendous power in attracting the audience to perform preventive behaviors. The results show that the language reflects the culture, opinions and needs of people in the society. Also, the results show that encouraging people to perform preventive behaviors should be through the integration of medical information with motivational linguistic factors in order to attract the audience more. Conclusions It can be concluded that the use of the appropriate pattern of medical advertising discourse and correct communication strategies, will help public participation in the field of epidemic control. The language of effective health education and health communication during an epidemic must be related to the ways of thinking and speaking of ordinary people. Also, words with metaphorical and ironic meanings have a high potential to influence the health performance of people in society and increase public awareness of health communication. Therefore, using them to create a new value system with the aim of controlling and overcoming the consequences of the epidemic is very effective.

Clinical pathways (CPWs) are a common component in the quest to improve the quality of health. CPWs are used to reduce variation, improve quality of care, and maximize the outcomes for specific groups of patients. An ongoing challenge is the operationalization of a definition of CPW in healthcare. This may be attributable to both the differences in definition and a lack of conceptualization in the field of clinical pathways. This correspondence article describes a process of refinement of an operational definition for CPW research and proposes an operational definition for the future syntheses of CPWs literature. Following the approach proposed by Kinsman et al. (BMC Medicine 8(1):31, 2010) and Wieland et al. (Alternative Therapies in Health and Medicine 17(2):50, 2011), we used a four-stage process to generate a five criteria checklist for the definition of CPWs. We refined the operational definition, through consensus, merging two of the checklist’s criteria, leading to a more inclusive criterion for accommodating CPW studies conducted in various healthcare settings. The following four criteria for CPW operational definition, derived from the refinement process described above, are (1) the intervention was a structured multidisciplinary plan of care; (2) the intervention was used to translate guidelines or evidence into local structures; (3) the intervention detailed the steps in a course of treatment or care in a plan, pathway, algorithm, guideline, protocol or other ‘inventory of actions’ (i.e. the intervention had time-frames or criteria-based progression); and (4) the intervention aimed to standardize care for a specific population. An intervention meeting all four criteria was considered to be a CPW. The development of operational definitions for complex interventions is a useful approach to appraise and synthesize evidence for policy development and quality improvement.

Background Clinical medicine has lagged behind other fields in understanding and utilizing frameworks to guide research. In this article, we introduce a new framework to examine why women choose mastectomy versus breast conserving therapy in early stage breast cancer, and highlight the importance of utilizing a conceptual framework to guide clinical research. Methods The framework we present was developed through integrating previous literature, frameworks, theories, models, and the author’s past research. Results We present a conceptual framework that illustrates the central domains that influence women’s choice between mastectomy versus breast conserving therapy. These have been organized into three broad constructs: clinicopathological factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and individual belief factors. The aim of this framework is to provide a comprehensive basis to describe, examine, and explain the factors that influence women’s choice of mastectomy versus breast conserving therapy at the individual level. Conclusion We have developed a framework with the purpose of helping health care workers and policy makers better understand the multitude of factors that influence a patient’s choice of therapy at an individual level. We hope this framework is useful for future scholars to utilize, challenge, and build upon in their own work on decision-making in the setting of breast cancer. For clinician-researchers who have limited experience with frameworks, this paper will highlight the importance of utilizing a conceptual framework to guide future research and provide an example.

Multiple drug resistant (MDR) malignancy remains a predictable and often terminal event in cancer therapy, and affects individuals with many cancer types, regardless of the stage at which they were originally diagnosed or the interval from last treatment. Protein biomarkers of MDR are not globally used for clinical decision-making, but include the overexpression of drug-efflux pumps (ABC transporter family) such as MDR-1 and BCRP, as well as HIF1α, a stress responsive transcription factor found elevated within many MDR tumors. Here, we present the important in vitro discovery that the development of MDR (in breast cancer cells) can be prevented, and that established MDR could be resensitized to therapy, by adjunct treatment with metformin. Metformin is prescribed globally to improve insulin sensitivity, including in those individuals with Type 2 Diabetes Mellitus (DM2). We demonstrate the effectiveness of metformin in resensitizing MDR breast cancer cell lines to their original treatment, and provide evidence that metformin may function through a mechanism involving post-translational histone modifications via an indirect histone deacetylase inhibitor (HDACi) activity. We find that metformin, at low physiological concentrations, reduces the expression of multiple classic protein markers of MDR in vitro and in preliminary in vivo models. Our demonstration that metformin can prevent MDR development and resensitize MDR cells to chemotherapy in vitro, provides important medical relevance towards metformin's potential clinical use against MDR cancers.

The availability of several treatment options for prostate cancer creates a situation where patients may need to come to a shared decision with their health-care team regarding their care. Shared decision-making (SDM) is the concept of a patient and a health-care professional collaborating to make decisions about the patient’s treatment course. Nurse navigators (NNs) are health-care professionals often involved in the SDM process. The current project sought to evaluate the way in which patients with prostate cancer make decisions regarding their care and to determine patients’ perspectives of the role of the NN in the SDM process. Eleven participants were recruited from the Prostate Assessment Centre by a NN. They were interviewed via telephone and their responses were analyzed using thematic analysis. Five interacting factors were determined to influence the way participants made decisions including level of anxiety, desire to maintain normalcy, support system quality, exposure to cancer narratives, and extent of practical concerns. NNs were found to increase knowledge, decrease indecision, and provide reassurance for participants. Based on the beneficial aspects of NN interaction reported in this study, the use of NNs in SDM programs should be encouraged. The results of the study demonstrate the complexity of the decision-making process when it comes to prostate cancer treatment. The factors elucidated in the study should be considered during the development and implementation of prostate cancer SDM programs.

Background Shared Decision-making (SDM), a medical decision-making model, was popularized in the late 1980s in reaction to then predominate paternalistic decision-making, aiming to better meet the needs of patients. Extensive research has been conducted internationally examining the benefits of SDM implementation; however, existing theory on how SDM works, for whom, in which circumstances , and why is limited. While literature has shown positive patient, health care provider, and system benefits (SDM outputs), further research is required to understand the nuances of this type of decision-making. As such, we set out to address: “In which situations, how, why, and for whom does SDM between patients and health care providers contribute to improved engagement in the Shared Decision-making process?” Methods To achieve our study goals we conducted a seven-step realist synthesis process, which included: (1) preliminary program theory development, (2) search strategy development, (3) selection and appraisal of literature in accordance with realist methodology, (4) data extraction, (5) identification of relevant formal theories, (6) data analysis and synthesis, and (7) formation of a revised program theory with the input of stakeholders. This process was done in accordance with RAMESES guidelines and publication standards for a realist synthesis. Expert consultations were also held to ensure consistency within the SDM literature. Results Through our realist synthesis, we developed a program theory of SDM which includes three contexts (pre-existing relationship, difficulty of decision, and system support), eight mechanism sets (anxiety, trust, perception of other party capacity, perception of time, self-efficacy, world view, perception of capacity to external support, and recognition of decision), and one outcome (engagement in SDM). Conclusions As far as the authors of this paper are aware, this paper is the first to begin unpacking how SDM works, for whom , in which circumstances , and why. By examining key mechanism sets and exploring how they facilitate or inhibit SDM, we have produced a program theory that may assist health care professionals, policy makers, and patients. While further research is suggested to further unpack the concepts identified within this paper, this provides an initial understanding into the theory behind SDM.

Saskatchewan has implemented care pathways for several common health conditions. To date, there has not been any cost-effectiveness evaluation of care pathways in the province. The objective of this study was to evaluate the real-world cost-effectiveness of a chronic obstructive pulmonary disease (COPD) care pathway program in Saskatchewan. Using patient-level administrative health data, we identified adults (35+ years) with COPD diagnosis recruited into the care pathway program in Regina between April 1, 2018, and March 31, 2019 (N = 759). The control group comprised adults (35+ years) with COPD who lived in Saskatoon during the same period (N = 759). The control group was matched to the intervention group using propensity scores. Costs were calculated at the patient level. The outcome measure was the number of days patients remained without experiencing COPD exacerbation within 1-year follow-up. Both manual and data-driven policy learning approaches were used to assess heterogeneity in the cost-effectiveness by patient demographic and disease characteristics. Bootstrapping was used to quantify uncertainty in the results. In the overall sample, the estimates indicate that the COPD care pathway was not cost-effective using the willingness to pay (WTP) threshold values in the range of $1,000 and $5,000/exacerbation day averted. The manual subgroup analyses show the COPD care pathway was dominant among patients with comorbidities and among patients aged 65 years or younger at the WTP threshold of $2000/exacerbation day averted. Although similar profiles as those identified in the manual subgroup analyses were confirmed, the data-driven policy learning approach suggests more nuanced demographic and disease profiles that the care pathway would be most appropriate for. Both manual subgroup analysis and data-driven policy learning approach showed that the COPD care pathway consistently produced cost savings and better health outcomes among patients with comorbidities or among those relatively younger. The care pathway was not cost-effective in the entire sample.

Background In Saskatchewan, Canada, Indigenous cancer care services at the municipal, provincial, and federal levels are intended to improve quality care but can result in a complex, fragmented, and multi-jurisdictional health care system. A multi-phase needs assessment project was initiated to document Indigenous cancer care needs. Guided by Indigenous patient partners, clinicians, academics, and policy makers, the present study reflects a needs assessment of Indigenous cancer supports from the perspectives of cancer care service providers. Methods Qualitative data were collected through three focus groups with 20 service providers for cancer patients and their families at three Saskatchewan cities. Participants included chemotherapy and radiation nurses, social workers, a patient navigator, dieticians, and practicum students. A semi-structured interview guide was used to conduct the sessions to allow for freedom of responses. Data were recorded, transcribed verbatim, and analyzed using thematic analysis. Results Service providers’ perspectives were categorized into five themes: 1) addressing travel-related issues, 2) logistical challenges, 3) improvements to Indigenous-specific health care supports, 4) cultural sensitivity in health care, and 5) consistency in care. Supports provided differed for the two Indigenous groups, First Nations and Métis. Service providers made recommendations regarding how needs could be met. They saw language translation providers and Elder supports as important. Recommendations for improving travel were for medical taxis to include breaks so that passengers may alleviate any uncomfortable side effects of their cancer treatment. Further, Indigenous-specific accommodations were recommended for those requiring medical travel. These recommendations aligned with supports that are available in four other Canadian provinces. Conclusions These results identified gaps in supports and outlined recommendations to address barriers to cancer care from the perspectives of service providers. These recommendations may inform evidence-based health system interventions for Indigenous cancer patients and ultimately aim to improve cancer care services, quality of life, and health outcomes of Indigenous patients throughout their cancer journey.

Background Melanoma is one of the deadliest forms of skin cancer. Irreversible electroporation (IRE) is an innovative, non-thermal ablation technology for treating irresectable solid cancers. However, most IRE treatments are incapable of cancer eradication and only temporarily prolong patient survival. Methods In this study, we developed a novel IRE + Combo treatment regimen that combines IRE-ablation with Combo-adjuvant [CpG, anti-PD-L1 antibody (PD-L1-Ab) and CD40-agonist] and investigated its anti-tumor immunity in a mouse BL6-10 OVA (BL OVA ) melanoma model. Results We demonstrated that inclusion of the CD40-agonist in the IRE + Combo treatment regimen promoted a more robust CD8 + T cell response (6.89%) when compared with IRE + CpG/PD-L1-Ab (2.67%) or IRE alone (0.21%) treatments, leading to eradication of subcutaneous BL OVA melanoma in 5/8 of BL OVA -bearing mice and simultaneous elimination of lung melanoma metastases. Addition of CD40-agonist to the IRE + Combo treatment regimen also induced a higher frequency (17.1%) of CD8 + CD103 + conventional type-1 dendritic cells (cDC1s) with up-regulated expression of CD54, CD80, MHC II, Bcl-xL and 41BBL in tumor-drainage lymph nodes (TDLNs) relative to the control IRE + CpG/PD-L1-Ab (12.1%) and IRE alone (9.0%) treatment groups. We also show that CD40-agonist stimulated a higher frequency of CD103 + TCF1 + tissue-resident memory T (T RM ) cells (32.1%) in TDLNs when compared with the two control (15.3% and 6.7%) treatment groups, and that these T RM cells exhibited enhanced mitochondrial content and greater relative expression of the effector cytokines IFN-γ and TNF-α and the transcriptional regulators TRAF1, p38-MAPK and PGC-1α. Conclusion Taken together, this study establishes that the CD40-agonist greatly potentiates the efficacy of IRE-ablation for metastatic melanoma by promoting unexpected CD8 + CD103 + cDC1 and CD103 + TCF1 + T RM cell responses and suggests the importance of targeting CD40-signaling to improve the efficacy of cancer IRE-ablation therapy.

Background Afghan refugees in Iran, estimated at over 5 million, represent a large vulnerable population whose attitudes towards COVID-19 vaccination are crucial to understand. Methods This cross-sectional study was conducted in Shiraz, Iran, in 2023. Adult Afghan refugees with children aged 5–17 were recruited using a snowball sampling method. A previously validated survey tool was adapted for the Afghan population in this study to assess underlying sociodemographic and psychosocial factors influencing the COVID-19 vaccine acceptance. Results Among 400 participants, 79% had received at least one dose, 57% were fully vaccinated, and 12% had received booster doses. Female gender (aOR: 2.070, 95% CI: 1.118–3.831), a history of COVID-19 in family or friends (aOR: 2.541, 95% CI: 1.393–4.636), adherence to routine childhood vaccinations for their children (aOR: 3.287, 95% CI: 1.738–6.215), trust in healthcare providers and media (aOR: 1.929, 95% CI: 1.287–2.889), and confidence in vaccine safety (aOR: 3.058, 95% CI: 2.155–4.329) were significantly associated with increased vaccine acceptance. Additionally, 59.8% of the participants vaccinated their children against COVID-19. A history of chronic diseases in participants (aOR: 2.470, 95% CI: 1.290–4.731), their own acceptance of the COVID-19 vaccine (aOR: 18.055, 95% CI: 8.206–39.724), a history of routine childhood vaccinations in children (aOR: 2.050, 95% CI: 1.103–3.810), and confidence in vaccine safety (aOR: 1.457, 95% CI: 1.04–2.032) were significantly associated with children vaccination. Conclusions Trust in healthcare providers/media and confidence in vaccine safety, were associated with higher vaccine uptake among Afghan refugees. Targeted communication and trust-building strategies are vital to address vaccine hesitancy, especially among vulnerable populations.
