Exploring the advances of single-cell RNA sequencing in thyroid cancer: a narrative review.

Thyroid cancer, a prevalent form of endocrine malignancy, has witnessed a substantial increase in occurrence in recent decades. To gain a comprehensive understanding of thyroid cancer at the single-cell level, this narrative review evaluates the applications of single-cell RNA sequencing (scRNA-seq) in thyroid cancer research. ScRNA-seq has revolutionised the identification and characterisation of distinct cell subpopulations, cell-to-cell communications, and receptor interactions, revealing unprecedented heterogeneity and shedding light on novel biomarkers for therapeutic discovery. These findings aid in the construction of predictive models on disease prognosis and therapeutic efficacy. Altogether, scRNA-seq has deepened our understanding of the tumour microenvironment immunologic insights, informing future studies in the development of effective personalised treatment for patients. Challenges and limitations of scRNA-seq, such as technical biases, financial barriers, and ethical concerns, are discussed. Advancements in computational methods, the advent of artificial intelligence (AI), machine learning (ML), and deep learning (DL), and the importance of single-cell data sharing and collaborative efforts are highlighted. Future directions of scRNA-seq in thyroid cancer research include investigating intra-tumoral heterogeneity, integrating with other omics technologies, exploring the non-coding RNA landscape, and studying rare subtypes. Overall, scRNA-seq has transformed thyroid cancer research and holds immense potential for advancing personalised therapies and improving patient outcomes. Efforts to make this technology more accessible and cost-effective will be crucial to ensuring its widespread utilisation in healthcare.

Journey across the world to study medicine: The Anandi Joshi story.

Women faced significant barriers to pursue education in the 19th century, yet modern history has witnessed bold women overcoming insurmountable odds in this quest. To this end, Anandi Joshi braved monumental odds to successfully become the first female physician in India. Born in 1865, Anandi was one of 10 children. Her zeal for knowledge was noted early by her father, who ensured that his daughter was well-educated. She married Gopalrao Joshi as a child when she was nine; a practice that was common at the time. Anandi's quest to become a physician stemmed from a traumatic event which saw the death of her child due to the lack of medical care. Despite the numerous prevalent barriers which prevented women from indulging in education, Anandi was determined. She travelled to the United States, where through sheer persistence, she was admitted to the Women's Medical College of Pennsylvania, where she graduated with a Doctor of Medicine (MD) degree in 1886. She subsequently returned to her home country, making her the first female physician in India. Despite her untimely death, Anandi became immortalised as a legend, a beacon of hope, and continues to serve as an inspiration for generations of Indian women.

Prevalence of irritable bowel syndrome and functional dyspepsia and their relationship with generalized anxiety disorder among medical students in Karachi.

OBJECTIVE: To assess the prevalence of inflammatory bowel syndrome and functional dyspepsia in medical students and their relationship with generalised anxiety disorder and other relevant factors. METHODS: The descriptive cross-sectional study was conducted in Karachi from August to November 2020 after approval from the ethics review board of Jinnah Sindh Medical University, and comprised students of either gender aged at least 18 years from different medical colleges in the city. Data was collected using validated tools Rome III criteria for inflammatory bowel syndrome and functional dyspepsia and Generalised Anxiety Disorder-7. Data was analysed using SPSS 26. RESULTS: Of the 305 subjects, 185(60.70%) were male and 120(39.30%) were female. The overall mean age was 21.43±2.13 years. The prevalence of inflammatory bowel syndrome was 17(5.57%), while that of functional dyspepsia was 2(0.66%). Further, 122(40%) students had minimal anxiety, 112(36.72%) mild, 43(14.10%) moderate and 28(9.18%) had severe anxiety. There was no significant relationship of either inflammatory bowel syndrome or functional dyspepsia diagnosis with generalised anxiety disorder (p>0.05), but a significant relationship existed between inflammatory bowel syndrome diagnosis and generalised anxiety disorder score (p=0.041). Significant relationships were found between inflammatory bowel syndrome diagnosis and use of non-steroidal anti-inflammatory drugs. The relationship of generalised anxiety disorder diagnosis with gender and probiotic use was significant (p<0.05), and so was the relationship of generalised anxiety disorder score with gender and level of physical activity (p<0.05). CONCLUSIONS: Medical students with a higher generalised anxiety disorder score and those who used non-steroidal anti-inflammatory drugs frequently had a higher likelihood of developing inflammatory bowel syndrome.

COVID-Well Study: Qualitative Evaluation of Supported Wellbeing Centres and Psychological First Aid for Healthcare Workers during the COVID-19 Pandemic.

Supported wellbeing centres were set up in UK hospital trusts as an early intervention aimed at mitigating the psychological impact of COVID-19 on healthcare workers. These provided high quality rest spaces with peer-to-peer psychological support provided by National Health Service (NHS) staff volunteers called 'wellbeing buddies', trained in psychological first aid. The aim of the study was to explore the views of centre visitors and operational staff towards this COVID-19 workforce wellbeing provision. Qualitative semi-structured interviews were undertaken with twenty-four (20F, 4M) employees from an acute hospital trust in the UK. Interviews were digitally recorded and transcribed, data were handled and analysed using thematic analysis. Interviews generated 3 over-arching themes, and 13 sub-themes covering 'exposure and job roles', 'emotional impacts of COVID-19 and 'the wellbeing centres'. Supported wellbeing centres were viewed as critical for the wellbeing of hospital employees during the first surge of COVID-19 in the UK. Wellbeing initiatives require managerial advocacy and must be inclusive. Job-related barriers to work breaks and accessing staff wellbeing provisions should be addressed. High quality rest spaces and access to peer-to-peer support are seen to benefit individuals, teams, organisations and care quality. Training NHS staff in psychological first aid is a useful approach to supporting the wellbeing of the NHS workforce during and beyond the COVID-19 pandemic.

Surface modification for osseointegration of Ti6Al4V ELI using powder mixed sinking EDM.

Biomedical implant rejection due to micromotion and inflammation around an implant leads to osteolysis and eventually has an implant failure because of poor osseointegration. To enhance osseointegration, the implant surface modification both at the nano and micro-scale levels is preferred to result in an enhanced interface between the body tissue and implant. The present study focuses on the modification of the surface of Titanium (α+ß) ELI medical grade alloy using powder-mixed electric discharge machining (PMEDM). Pulse current, on/off time, and various silicon carbide (SiC) powder concentrations are used as input parameters to comprehend desired surface modifications. Powder concentration is considered as the most important factor to control surface roughness and recast layer depth. A significant decrease in surface fracture density and roughness is observed using a 20 g/l concentration of SiC particles. Elemental mapping analysis has confirmed the migration of Si and the generation of promising surface texture and chemistry. Oxides and carbides enriched surface improved the microhardness of the re-solidified layer from 320 HV to 727 HV. Surface topology reveals nano-porosity (50-200 nm) which enhances osseointegration due to the absorption of proteins especially collagen to the surface.
