Recent developments in targeting breast cancer stem cells (BCSCs): a descriptive review of therapeutic strategies and emerging therapies.

Despite recent advancements in the diagnosis and treatment of breast cancer (BC), patient outcomes in terms of survival, recurrence, and disease progression remain suboptimal. A significant factor contributing to these challenges is the cellular heterogeneity within BC, particularly the presence of breast cancer stem cells (BCSCs). These cells are thought to serve as the clonogenic nexus for new tumor growth, owing to their hierarchical organization within the tumor. This descriptive review focuses on the evolving strategies to target BCSCs, which have become a pivotal aspect of therapeutic development. We explore a variety of approaches, including targeting specific tumor surface markers (CD133 and CD44), transporters, heat shock proteins, and critical signaling pathways like Notch, Akt, Hedgehog, KLF4, and Wnt/ß-catenin. Additionally, we discuss the modulation of the tumor microenvironment through the CXCR-12/CXCR4 axis, manipulation of pH levels, and targeting hypoxia-inducible factors, vascular endothelial growth factor, and CXCR1/2 receptors. Further, this review focuses on the roles of microRNA expression, strategies to induce apoptosis and differentiation in BCSCs, dietary interventions, dendritic cell vaccination, oncolytic viruses, nanotechnology, immunotherapy, and gene therapy. We particularly focused on studies reporting identification of BCSCs, their unique properties and the efficacy of various therapeutic modalities in targeting these cells. By dissecting these approaches, we aim to provide insights into the complex landscape of BC treatment and the potential pathways for improving patient outcomes through targeted BCSC therapies.

Mental health outcomes in health care providers during the COVID-19 pandemic: an umbrella review.

As we head into the third year of the COVID-19 pandemic, there is an increasing need to consider the long-term mental health outcomes of health care workers (HCWs) who have experienced overwhelming work pressure, economic and social deprivation, burnout, and post-traumatic stress disorder (PTSD). This scoping umbrella review summarizes the mental health outcomes of published evidence syntheses on HCWs worldwide. We analyzed 39 evidence syntheses representing the findings from 1297 primary studies. We found several persistent fears and concerns (job-related fears, fear of stigmatization, worries about the pandemic, and infection-related fears) that shaped HCW experiences in delivering health care. We also describe several risk factors (job-related, social factors, poor physical and mental health, and inadequate coping strategies) and protective factors (individual and external factors). This is the first scoping umbrella review comprehensively documenting the various risk and protective factors that HCWs have faced during the COVID-19 pandemic. HCWs continue to fear the risk that they may infect their family and friends since they regularly interact with COVID-19 patients. This places HCWs in a precarious situation requiring them to balance risk to their family and friends and potential social deprivation from isolation.

This review summarizes the mental health outcomes of health care workers (HCWs) during the COVID-19 pandemic, including their worries and concerns. The fear of infecting loved ones was one of the essential fears faced by HCWs. Job-related fears included job instability, career uncertainty, the fear of losing control in the workplace, and increased workload. Furthermore, HCWs expressed concerns about stigmatization and uncertainty associated with the pandemic's magnitude, duration, and effects. Several risk factors and protective factors for the mental health of HCWs were identified in this review. Risk factors included the lack of personal protective equipment (PPE), the increased workload, the lack of timely information regarding the pandemic, involuntary conscription, social restrictions, pre-existing physical and mental illnesses, and improper coping strategies. In contrast, protective factors included personal characteristics such as altruism and humor, perceived control and self-efficacy, adequate training and education regarding the pandemic, adequate supply of PPE, and favorable work environments. These findings can serve as a basis for the formulation of interventions by governing bodies that promote the mental health of HCWs.

Management of an extensive frontal pyocoele using an external approach: A case report.

Pyocoeles of the paranasal sinuses are pus-filled cavities seen in the sinuses and develop from the infection of the mucocoeles. Pyocoeles most commonly form in the frontal sinus. Endoscopic Sinus Surgery is currently the mainstay of the treatment. We present the case of an 85-year-old female who presented to the ENT OPD of Jinnah Hospital/AIMC, Lahore, in October 2017 with complaints of progressive symptoms of intractable left frontal pain, double vision, and an associated swelling below the medial half of the left eyebrow. A CT scan was done and a diagnosis of extensive frontal pyocoele was made. She was treated successfully with an external approach and remained without any complications till 13-month follow-up after surgery; exceptional cosmetic results were achieved. We wish to bring attention to the possibility of an external approach being used as a primary intervention, if deemed appropriate.

A Systematic Map of Non-Clinical Evidence Syntheses Published Globally on COVID-19.

STUDY OBJECTIVE: Evidence syntheses perform rigorous investigations of the primary literature and they have played a vital role in generating evidence-based recommendations for governments worldwide during the Covid-19 pandemic. However, there has not yet been an attempt to organize them by topic and other characteristics. This study performed a systematic mapping exercise of non-clinical evidence syntheses pertaining to Covid-19. METHODS: This study conducted a systematic search on December 5, 2020 across 10 databases and servers: CINAHL (EBSCO Information Services, Ipswich, Massachusetts, United States), Embase (Elsevier, Aalborg, Denmark), Global Health (EBSCO Information Services, Ipswich, Massachusetts, United States), Healthstar (NICHSR and AHA, Bethesda, United States), MEDLINE (NLM, Bethesda, United States), PsychINFO (APA, Washington, DC, United States), Web of Science (Clarivate Analytics, London, UK), Research Square (Research Square, Durham, North Carolina), MEDRxiv (Cold Spring Harbor Laboratory, New York, United States), and PROSPERO (NIHR, York, United Kingdom). Only full evidence syntheses published in a peer-reviewed journal or preprint server were included. RESULTS: This study classified all evidence syntheses in the following topics: health service delivery (n = 280), prevention and behavior (n = 201), mental health (n = 140), social epidemiology (n = 31), economy (n = 22), and environment (n = 19). This study provides a comprehensive resource of all evidence syntheses categorized according to topic. CONCLUSIONS: This study proposes the following research priorities: governance, the impact of Covid-19 on different populations, the effectiveness of prevention and control methods across contexts, mental health, and vaccine hesitancy.

Successful Resident Engagement in Quality Improvement: The Detroit Medical Center Story.

Background In 2014, the Detroit Medical Center launched a new program to engage residents and fellows in a strategy to deliver optimal care within 1 year, focusing on quality at an earlier stage of their careers and preparing them for working posttraining. Methods Residents from clinically relevant residency and fellowships programs were selected to be Resident Quality Directors. The project involved development of an interactive electronic health record (EHR) checklist to visually depict real time gaps in 40 process measures, while focusing on 14 areas related to stroke and venous thromboembolism (VTE) prophylaxis. We also implemented an incentive approach, using a pay-for-performance (P4P) model. Results The project included 800 residents led by 14 resident quality directors. We were able to achieve 100% resident participation. Prior compliance with VTE quality measures 6 months was 88.5%, with performance increasing to 94.2% (P < .006) at 6 months and 100% at 12 months (P < .005) after the intervention. The VTE prophylaxis score improved from the 89.7% to 92.9% range at inception to 100% by 12 months. A similar steady improvement of stroke process measures was observed, with a 100% compliance within 12 months. The institution made 4 incentive payments to trainees (ranging from $300 to $4,000 per year). The remaining 26 process measures remained at goal with above 95% compliance. Conclusions This quality improvement initiative was associated with system-wide quality performance on VTE prevention and stroke care process measures, which was facilitated by a interactive EHR-based checklist and linkage to P4P incentive payments.
