The ability to regenerate damaged myocardium with tissue derived from embryonic stem (ES) cells is currently undergoing extensive investigation. As a prerequisite to transplantation therapy, strategies must be developed to induce ES cells to the cardiac phenotype. Toward this end, cues from mechanisms of embryonic indu…

BACKGROUND: Distinguishing true tumor progression from pseudoprogression (PsP) and radiation necrosis (RN) following radiotherapy or radiosurgery for intracranial tumors remains a significant clinical challenge. Conventional imaging modalities, including MRI and PET, often lack sufficient diagnostic accuracy, while his…

BACKGROUND: Seasonal affective disorder (SAD) is a seasonal pattern of recurrent major depressive episodes that most commonly occurs during autumn or winter and remits in spring. The prevalence of SAD ranges from 1.5% to 9%, depending on latitude. The predictable seasonal aspect of SAD provides a promising opportunity…

UNLABELLED: OBJECTIVE OF ANALYSIS: The objective of this analysis is to examine the safety and effectiveness of percutaneous vertebroplasty for treatment of osteoporotic vertebral compression fractures (VCFs) compared with conservative treatment. CLINICAL NEED AND TARGET POPULATION: Osteoporosis and associated fractur…

BACKGROUND: Seasonal affective disorder (SAD) is a seasonal pattern of recurrent major depressive episodes that most commonly starts in autumn or winter and remits in spring. The prevalence of SAD depends on latitude and ranges from 1.5% to 9%. The predictable seasonal aspect of SAD provides a promising opportunity for…

BACKGROUND: Earlier studies of breast cancer, screening mammography, and mortality reduction may have inflated lifetime and long-term risk estimates for invasive breast cancer due to limitations in their data collection methods and interpretation. OBJECTIVE: To estimate the percentage of asymptomatic peri/postmenopaus…

There is concern that cyclooxygenase (COX)-2 inhibitors may promote atherothrombosis by inhibiting vascular formation of prostacyclin (PGI2) and an increased thrombotic risk of COX-2 inhibitors has been reported. It is widely accepted that the prothrombotic effects of COX-2 inhibitors can be explained by the removal of…

BACKGROUND: Acute promyelocytic leukemia (APL) is an aggressive malignancy. Although recent advancements in therapy have improved outcomes, differing toxicity profiles remain. The optimal choice between all-trans retinoic acid plus arsenic trioxide (ATRA + ATO) and ATRA plus chemotherapy, in newly diagnos…

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatohepatitis (MASH) with cirrhosis lacks definitive treatments and poses an increasing healthcare burden globally. We undertook a systematic literature review (SLR) to better understand the disease burden in cirrhosis due to MASH. METHODS: The SLR was conducted…

Natural antimicrobials (NA) have stood out in the last decade due to the growing demand for reducing chemical preservatives in food. Once solubility, stability, and changes in sensory attributes could limit their applications in foods, several studies were published suggesting micro-/nanoencapsulation to overcome such…

BACKGROUND: Stringent glycemic control by using insulin as a replacement or in addition to oral hypoglycemic agents (OHAs) has been recommended for people with tuberculosis and diabetes mellitus (TB-DM). This systematic review (PROSPERO 2016:CRD42016039101) analyses whether this improves TB treatment outcomes. OBJECTI…

OBJECTIVES: Delays in identification, resuscitation and referral have been identified as a preventable cause of avoidable severity of illness and mortality in South African children. To address this problem, a machine learning model to predict a compound outcome of death prior to discharge from hospital and/or admissio…

BACKGROUND: Health professions educators require support to develop teaching and learning, research, educational leadership, and administrative skills to strengthen their higher education role through faculty development initiatives. Where administration has pursued face-to-face and online faculty development initiativ…

INTRODUCTION: The process of adapting to a life with a chronic illness, is a well-researched phenomenon for a number of common chronic illnesses. The construct, adaptation, embeds the notions of integration of the chronic illness into identity and self-management. Integration precedes self-management and is key to livi…

BACKGROUND: It is established that videolaryngoscopy improves intubation success rates and views compared with direct laryngoscopy. However, concerns regarding default adoption of videolaryngoscopy include a negative impact on skill acquisition for direct laryngoscopy. This study aimed to assess the utility of Macintos…

INTRODUCTION: Chronic liver disease is a growing cause of morbidity and mortality in the UK. Acute presentation with advanced disease is common and prioritisation of resources to those at highest risk at earlier disease stages is essential to improving patient outcomes. Existing prognostic tools are of limited accuracy…

BACKGROUND: We sought to investigate the relative impact of the timing of the administration of immunotherapy on survival in patients with resectable lung cancer. METHODS: We conducted a systematic review and meta-analysis of randomised controlled trials in this setting. We searched MEDLINE, EMBASE, LILACS and Cochran…
