Background: Despite its long-term history, haematopoietic stem cell transplantation (HSCT) still faces challenges in several countries under development and especially in the private health sector.

Objectives Design And Methods: In this retrospective analysis, we present our experience and the results of 48 adult patients who underwent HSCT (autologous 37, allogeneic 9) at a private-sector hospital in Abu Dhabi, United Arab Emirates (UAE). The main indications were multiple myeloma and acute myeloid leukaemia in the autologous and allogeneic setting, respectively.

Article Synopsis
  • Stem cells exist in a dormant state within various tissues and can differentiate into new cells when needed, with mesenchymal stem cells being notable for their potential in tissue regeneration and immunomodulation.
  • They release substances like paracrine factors and exosomes, which have various benefits such as reducing inflammation and promoting healing, indicating their importance in cell therapy and regenerative medicine.
  • Aging hampers stem cells' ability to self-renew and differentiate, limiting regeneration, but advancements in therapy guidelines and clinical trials suggest that stem cell transplantation could be vital for combating age-related tissue damage.

Background: Biologic therapies approved for treating chronic rhinosinusitis with nasal polyps (CRSwNP) have well-established safety profiles but reports of rheumatic adverse events (AEs) are increasing and not well defined. This review aims to assess the risk and incidence of rheumatic AEs associated with biologic therapy in CRSwNP and summarize current reported management strategies.

Methods: A protocol was registered in PROSPERO [CRD42024525663].

Article Synopsis
  • Higher rates of cardiac implantable electronic device (CIED) implantations are linked to increased lead failures and the need for transvenous lead extractions (TLE), prompting this study to evaluate TLE admissions and safety outcomes from 2016 to 2019.* -
  • The study analyzed 30,128 TLE hospitalizations, finding a 3.21% in-hospital mortality rate, with factors like age and existing health conditions raising mortality; those with a history of sternotomy fared better than those without.* -
  • Despite a low overall mortality rate, female patients experienced more cardiac tamponade but had shorter hospital stays and lower costs, with no significant gender difference in mortality rates.*

Thermal treatment has emerged as a promising approach for either the end-of-life treatment or regeneration of granular activated carbon (GAC) contaminated with per- and polyfluoroalkyl substances (PFAS). However, its effectiveness has been limited by the requirement for high temperatures, the generation of products of incomplete destruction, and the necessity to scrub HF in the flue gas. This study investigates the use of common alkali and alkaline-earth metal additives to enhance the mineralization of perfluorooctanesulfonate (PFOS) adsorbed onto GAC.

There is considerable interest in addressing soils contaminated with per- and polyfluoroalkyl substances (PFAS) because of the PFAS in the environment and associated health risks. The neutralization of PFAS in situ is challenging. Consequently, mobilizing the PFAS from the contaminated soils into an aqueous solution for subsequent handling has been pursued.

Background: Racialised trainees in Canada and the USA continue to disproportionately experience discrimination and harassment in learning environments despite equity, diversity, and inclusion (EDI) reform efforts. Using critical approaches to understand what problems have been conceptualised and operationalised as EDI issues within postgraduate medical education (PGME) is important to inform ongoing learning environment reform in resident training.

Methods: We conducted a critical narrative review of EDI literature from 2009-2022 using critical race theory (CRT) and the concept of intersectionality to analyse how issues of discrimination in PGME have been studied.

Background: Lymph node metastases are associated with poor prognosis in oral cavity squamous cell carcinoma (OCSCC). In other cancers, clinical guidelines on the number of lymph nodes removed during primary surgery, lymph node yield (LNY), exist. Here, we evaluated the prognostic capacity of LNY on regional failure, locoregional recurrence, and disease-free survival (DFS) in patients with OCSCC treated by primary neck surgery.

The increasing need for mental health support and a shortage of therapists have led to the development of the eXtended-reality Artificial Intelligence Assistant (XAIA). This platform combines spatial computing, virtual reality (VR), and artificial intelligence (AI) to provide immersive mental health support. Utilizing GPT-4 for AI-driven therapy, XAIA engaged participants with mild-to-moderate anxiety or depression in biophilic VR environments.

Introduction: There is limited research examining the biopsychosocial impact of cyclic vomiting syndrome (CVS) on patients. This study aims to assess individuals' experiences, fears, and concerns associated with CVS and the impact of CVS on their daily lives.

Methods: We employed social netnography to analyze publicly available posts related to CVS that were identified from six US online forums and Twitter.

Background: Perianal fistulae can undermine physical, emotional, and social well-being in patients with Crohn's disease and are challenging to manage. Social media offers a rich opportunity to gain an in-depth understanding of the impact of perianal fistulae on patients' daily lives outside of controlled environments. In this study, we conducted social media analytics to examine patients' experiences with perianal fistulae and assessed the impact of perianal fistulae on patients' behavior and overall well-being.

  • Aging is when our bodies slowly lose strength and abilities needed to stay alive and reproduce over time.!
  • T-cells, a type of immune cell, change a lot as we get older, especially with things like telomeres and telomerase, which are important for keeping cells healthy.!
  • This text reviews how these changes in T-cells relate to health, aging, and diseases, especially cancers linked to short telomeres and telomerase problems.!

Thermal imaging cameras and infrared (IR) temperature measurement devices act as state-of-the-art techniques for non-contact temperature determination of the skin surface. The former is cost-intensive in many cases for widespread application, and the latter requires manual alignment to the measuring point. Due to this background, this paper proposes a new method for automated, non-contact, and area-specific temperature measurement of the facial skin surface.

Background: In addition to erectile dysfunction, urinary incontinence is the most common functional limitation after radical prostatectomy (RPE) for prostate cancer (PCa). The German S3 guideline recommends informing patients about possible effects of the therapy options, including incontinence. However, only little data on continence from routine care in German-speaking countries after RPE are currently available, which makes it difficult to inform patients.

Unlabelled: We used conjoint analysis-a method that assesses complex decision making-to quantify patients' choices when selecting an osteoporosis therapy. While 60% of people prioritized medication efficacy when deciding among treatments, the remaining 40% highly valued factors other than efficacy, suggesting the need for personalized shared decision-making tools.

Introduction: In this study, we aimed to examine patient decision-making surrounding osteoporosis medications using conjoint analysis.

Oil dispersion by the application of chemical dispersants is an important tool in oil spill response, but it is difficult to quantify in the field in a timely fashion that is useful for coordinators and decision-makers. One option is the use of rugged portable field fluorometers that can deliver essentially instantaneous results if access is attainable. The United States Coast Guard has suggested, in their Special Monitoring of Applied Response Technologies (SMART) protocols, that successful oil dispersion can be identified by a five-fold increase in oil fluorescence.

Stem cell-based therapies have been foreshowed as a promising therapeutic approach for the treatment of several diseases. However, in the cancer context, results obtained from clinical studies were found to be quite limited. Deeply implicated in inflammatory cues, Mesenchymal, Neural, and Embryonic Stem Cells have mainly been used in clinical trials as a vehicle to deliver and stimulate signals in tumors niche.
