A cost-effectiveness analysis of the use of oral ibrexafungerp versus fluconazole for acute vulvovaginal candidiasis in the UK NHS primary care service.

BACKGROUND: Vulvovaginal Candidiasis (VVC) is a fungal infection causing inflammation of the vagina and/or the vulva. Symptoms include itching, irritation, and discharge. VVC presents commonly across primary care and, despite its mild symptoms, carries psychological burden and has a significant impact on women's quality of life. UK guidelines support treatment via oral or topical azole antifungal agents. Recent evidence attests to the superiority of novel non-azole antifungals. Thus, rigorous financial assessment of both antifungals is necessary for optimal VVC treatment allocation in UK primary care. AIM: To evaluate the cost-effectiveness of ibrexafungerp against the gold standard fluconazole as first-line treatment of VVC within the NHS. METHOD: A systematic review on the efficacy of ibrexafungerp and fluconazole in acute VVC was conducted. Cost-effectiveness analysis was initiated using health outcome data from the DOVE trial, a Phase 2 RCT. Costs in pound sterling were ascertained in monetary units, and effectiveness determined as reduced need for follow-up medication. RESULTS: An incremental cost-effectiveness ratio of £2185.74 was determined. This suggests oral ibrexafungerp being largely more costly yet slightly more effective than fluconazole, and thus has unfavourable net benefit. Two sensitivity analyses were conducted considering follow-up medication combination and market price, which provided confidence in the calculated cost-effectiveness ratio. CONCLUSION: This analysis highlights fluconazole's cost-effectiveness in current UK guidelines and favourability.

Gender-Affirming Surgery in Low- and Middle-Income Countries: A Systematic Review.

Objectives: Fewer than one-fifth of all studies on gender-affirming care originate from low- and middle-income countries (LMICs). This is the first systematic review to examine surgical demographics and outcomes following gender-affirming surgery (GAS) in LMICs. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, five databases were systematically searched for original studies and case series on GAS within LMIC settings. Excluded reports included animal studies, non-English language studies, secondary studies including reviews, individual case reports and conference abstracts. Results: This review includes 34 studies involving n = 5064 TGNB individuals. Most studies (22, 64.7%) were from upper-middle-income countries, followed by lower-middle-income countries (12, 35.3%). A total of 31 studies (91.2%) reported on post-operative outcomes. Of n = 5013 patients who underwent GAS, 71.5% (n = 3584) underwent masculinizing and 29.5% (n = 1480) underwent feminizing procedures. The predominant procedures were metoidioplasty (n = 2270/3584, 63.3%) and vaginoplasty (n = 1103/1480, 74.5%). Mean follow-up was 47.7 months. In patients who underwent metoidioplasty, 6.8% (n = 155) of patients experienced a complication and 6.3% (n = 144) underwent revision surgery. In patients who underwent vaginoplasty, 11.5% (n = 127) of patients experienced a complication and 8.5% (n = 94) underwent revision surgery. Of the studies (25/34, 73.5%) that reported on quality of life and post-operative satisfaction, the majority showed marked improvements in psychosocial and functional outcomes. Notably, no post-surgical regret was reported among the surveyed patients. Conclusions: Existing literature on GAS in LMICs remains scarce and is concentrated in select institutions that drive specific procedures. Our review highlights the low reported volumes of GAS, variability in surgical outcomes and quality of life.

The Presence of Chronic Total Occlusion in Noninfarct-Related Arteries Is Associated With Higher Mortality and Worse Patient Outcomes Following Percutaneous Coronary Intervention for STEMI: A Systematic Review, Meta-Analysis and Meta-Regression.

Reperfusion therapy with percutaneous coronary intervention improves outcomes in patients with ST-elevation myocardial infarction. We conducted a meta-analysis to assess the impact of chronic total occlusion (CTO) in noninfarct-related artery on the outcomes of these patients. Comprehensive searches were performed using PubMed, Google Scholar, and EMBASE. The primary endpoint was the 30-day mortality rate, with secondary endpoints including all-cause mortality, repeat myocardial infarction, and stroke. Forest plots were created for the pooled analysis of the results, with statistical significance set at P < 0.05. A total of 19 studies were included in this meta-analysis, with 23,989 patients (3589 in CTO group and 20,400 in no-CTO group). The presence of CTO was associated with significantly higher odds of 30-day mortality [18.38% vs 5.74%; relative risk (RR), 3.69; 95% confidence intervals (CI), 2.68-5.07; P < 0.00001], all-cause mortality (31.00% vs 13.40%; RR, 2.79; 95% CI, 2.31-3.37; P < 0.00001), cardiovascular-related deaths (12.61% vs 4.1%; RR, 2.61; 95% CI, 1.99-3.44; P < 0.00001), and major adverse cardiovascular events (13.64% vs 9.88%; RR, 2.08; 95% CI, 1.52-2.86; P < 0.00001) than the non-CTO group. No significant differences in repeated myocardial infarction or stroke were observed between the CTO and non-CTO groups. Our findings underscore the need for further research on the benefits and risks of performing staged or simultaneous percutaneous coronary intervention for CTO in the noninfarct-related artery in patients with ST-elevation myocardial infarction.

Association between Acute and Chronic Inflammatory States: A Case-Control Study.

BACKGROUND: Fever is the hallmark of efficient acute inflammatory response, which may be disrupted in chronic inflammatory conditions. The "continuum theory" proposes that the return of acute inflammatory states with high fever predicts improvement in chronic diseases during treatment. Our objective was to investigate the observation made, during classical homeopathic treatment, that such an association exists between chronic inflammation and efficient acute inflammation. METHODS: In a case-control study, the reports of patients diagnosed with chronic inflammatory conditions with at least 6 months of follow-up under homeopathic treatment were retrospectively sampled from homeopathic medical practices from Greece, India, Romania and Russia. Twenty patients who improved under homeopathic treatment and 20 age-matched controls of those who did not improve were selected. The occurrence of common acute infectious diseases with fever during the follow-up period was investigated. RESULTS: The average age of the cases and controls was 28.4 (SD: 16.64) and 27.9 (SD: 17.19) years respectively. 18/20 cases and 4/20 controls developed common infectious diseases with fever. Cramer's V co-efficient value was found to be 0.551 (p < 0.01), indicating that improvement was more in patients with fever than without. Odds ratio of improving with respect to development of acute infectious diseases was 36.0 (95% CI: 5.8 to 223.5). The binary logistic regression model indicated significant contribution of occurrence of acute infections with fever as a predictor for improvement in chronic inflammatory disease. CONCLUSIONS: Classical homeopathic clinical observations indicate an association between chronic inflammatory status in the body and the ability to mount efficient acute inflammation. In this case-control study, the occurrence of common infections with fever during treatment heralded improvement in chronic inflammatory disease. Further powered studies are necessary to substantiate this finding.

Autologous breast reconstruction in low- and middle-income countries (LMICs): a systematic review of current practices and challenges.

INTRODUCTION: Efforts to improve global healthcare persist, yet LMICs face challenges accessing surgical care, especially breast reconstruction amidst rising breast cancer cases. This review evaluates the present state and challenges of autologous breast reconstruction in low- and middle-income countries (LMICs). EVIDENCE ACQUISITION: Utilizing the PRISMA guidelines and the Cochrane Collaboration's standards, databases such as EMBASE, MEDLINE, Cochrane, PubMed, and Google Scholar were examined for studies on breast reconstruction in LMICs (based on the World Bank's 2022-2023 definitions) up to August 2022. Articles and case reports focusing on autologous reconstruction following breast cancer surgery in these regions were incorporated. EVIDENCE SYNTHESIS: From an initial 288 articles, 19 met the criteria after thorough assessment. These articles documented 4899 patient cases from LMICs, with the breakdown being: 11 on LD flaps, nine on TRAM flaps, eight on DIEP flaps, two on TDAP flaps, and one on TMG flap. Flap necrosis emerged as the prevalent complication in four studies. CONCLUSIONS: While autologous breast reconstruction presents superior aesthetic benefits without notable long-term economic setbacks, its adoption in LMICs is limited. This is partly due to the domination of implant-based methods among patients and surgeons, selected due to convenience. The scarcity of concrete evidence and standardized metrics in LMICs clouds the understanding of this procedure. Despite its advantages, awareness is low, necessitating more training and awareness campaigns. Uniform reporting, quality data, and financial analysis can provide a comprehensive LMIC understanding, aiding future research.

Using energy to go downhill-a genoprotective role for ATPase activity in DNA topoisomerase II.

Type II topoisomerases effect topological changes in DNA by cutting a single duplex, passing a second duplex through the break, and resealing the broken strand in an ATP-coupled reaction cycle. Curiously, most type II topoisomerases (topos II, IV and VI) catalyze DNA transformations that are energetically favorable, such as the removal of superhelical strain; why ATP is required for such reactions is unknown. Here, using human topoisomerase IIß (hTOP2ß) as a model, we show that the ATPase domains of the enzyme are not required for DNA strand passage, but that their loss elevates the enzyme's propensity for DNA damage. The unstructured C-terminal domains (CTDs) of hTOP2ß strongly potentiate strand passage activity in ATPase-less enzymes, as do cleavage-prone mutations that confer hypersensitivity to the chemotherapeutic agent etoposide. The presence of either the CTD or the mutations lead ATPase-less enzymes to promote even greater levels of DNA cleavage in vitro, as well as in vivo. By contrast, aberrant cleavage phenotypes of these topo II variants is significantly repressed when the ATPase domains are present. Our findings are consistent with the proposal that type II topoisomerases acquired ATPase function to maintain high levels of catalytic activity while minimizing inappropriate DNA damage.

Machine learning algorithms for the prognostication of abdominal aortic aneurysm progression: a systematic review.

INTRODUCTION: Abdominal aortic aneurysm (AAA), often characterized by an abdominal aortic diameter over 3.0 cm, is managed through screening, surveillance, and surgical intervention. AAA growth can be heterogeneous and rupture carries a high mortality rate, with size and certain risk factors influencing rupture risk. Research is ongoing to accurately predict individual AAA growth rates for personalized management. Machine learning, a subset of artificial intelligence, has shown promise in various medical fields, including endoleak detection post-EVAR. However, its application for predicting AAA growth remains insufficiently explored, thus necessitating further investigation. Subsequently, this paper aims to summarize the current status of machine learning in predicting AAA growth. EVIDENCE ACQUISITION: A systematic database search of Embase, MEDLINE, Cochrane, PubMed and Google Scholar from inception till December 2022 was conducted of original articles that discussed the use of machine learning in predicting AAA growth using the aforementioned databases. EVIDENCE SYNTHESIS: Overall, 2742 articles were extracted, of which seven retrospective studies involving 410 patients were included using a predetermined criteria. Six out of seven studies applied a supervised learning approach for their machine learning (ML) models, with considerable diversity observed within specific ML models. The majority of the studies concluded that machine learning models perform better in predicting AAA growth in comparison to reference models. All studies focused on predicting AAA growth over specified durations. Maximal luminal diameter was the most frequently used indicator, with alternative predictors being AAA volume, ILT (intraluminal thrombus) and flow-medicated diameter (FMD). CONCLUSIONS: The nascent field of applying machine learning (ML) for Abdominal Aortic Aneurysm (AAA) expansion prediction exhibits potential to enhance predictive accuracy across diverse parameters. Future studies must emphasize evidencing clinical utility in a healthcare system context, thereby ensuring patient outcome improvement. This will necessitate addressing key ethical implications in establishing prospective studies related to this topic and collaboration among pivotal stakeholders within the AI field.

Readout-Segmented Echoplanar (RESOLVE) Diffusion-Weighted Imaging on 3T MRI in Detection of Cholesteatoma-Our Experience.

Background Several research studies have demonstrated the utility of diffusion-weighted imaging (DWI) in detecting middle ear cholesteatomas, especially with the non-echoplanar imaging (non-EPI) DWI technique. REadout Segmentation Of Long Variable Echo trains (RESOLVE), a multishot-EPI DWI, has better spatial resolution at a thinner section acquisition with reduced image distortion compared to the single-shot-EPI DWI technique. Purpose In this study, we evaluated the diagnostic ability of RESOLVE -DWI in middle ear cholesteatomas with surgical and histopathological support. Patients and Methods Fifty patients with clinical suspicion of primary cholesteatoma or postoperative recurrence were subjected to routine sequences and RESOLVE-DWI on magnetic resonance imaging (MRI). Thirty-eight patients had unilateral disease, while 12 patients had bilateral disease. The bilateral temporal bones of 50 patients were evaluated on MRI. The results attained by RESOLVE-DWI were correlated with intraoperative and histopathological findings. Results RESOLVE-DWI truly detected 55 of the 58 surgically proven cholesteatomas. RESOLVE-DWI could not detect three cholesteatoma lesions due to their small size and falsely diagnosed one case each of impacted wax and non-cholesteatomatous otitis media as cholesteatoma. With a 95% confidence interval, RESOLVE-DWI showed 94.8% sensitivity, 95.2% specificity, 96% positive predictive value, 93% negative predictive value, and 95% diagnostic accuracy in cholesteatoma detection. Conclusion RESOLVE-DWI is a sensitive and specific DWI technique for detecting middle ear cholesteatoma. However, RESOLVE-DWI has limitations in the diagnosis of small (<3 mm) cholesteatomas.

Outcomes of COVID-19 amongst patients with ongoing use of inhaled corticosteroids - a systematic review & meta-analysis.

Background: WHO quoted the numbers for the Coronavirus disease 2019 (COVID-19) pandemic as of August 2021 were 200 million cases with over 4 million deaths globally. COVID-19 is associated with several respiratory pathologies. Inhaled corticosteroids (ICS) are used to improve lung function by reducing inflammation, edema, mucus secretion, and inhibiting various cytokine activities. However, there is limited data on the effect of ICS usage in patients with COVID-19. In this study, we aim to evaluate the association between the use of ICS and the outcomes in COVID-19 patients compared to standard COVID-19 treatment. Methods: We followed PRISMA guidelines and MOOSE protocol for conducting the systematic review and meta-analysis comparing ICS and standard COVID-19 therapy. A search on PubMed is conducted yielding 270 articles of which 6 manuscripts are finalized for inclusion in the study. Patients with COVID-19 are identified from the studies based on confirmed positive RT-PCR tests. Hospitalization, ICU admission, and mortality are selected as the outcomes of our study. Using RevMan 5.3, we performed random-effects models to estimate the pooled effect size (pooled odds ratio), 95% confidence interval (95% CI), and heterogeneity (I2). Forest plots are obtained and p <0.05 is considered statistically significant. Results: Our study involves the comparison of ICS vs Non-ICS for mortality (N= 207,842 vs 166,217), ICU hospitalization (N= 1,084 vs 9,425), and the risk of hospitalization (N= 1,273 vs 1,676).Of the six studies, five reported mortality. We found a higher mortality rate in patients with asthma (60.88%, 107/160) and chronic obstructive pulmonary disease (COPD) (68.46%, 382/558) among ICS users. The overall mortality is 7.49% (107/1428). We found that ICS use was associated with higher odds of mortality (OR=1.45 95%CI: 1.10-1.91; p=0.009, I2= 68%) amongst COVID-19 patients. In subgroup analysis, higher odds of mortality among COPD patients using ICS was noted [pooled OR: 1.52 (1.24-1.86); p<0.0001; I2=0%]. However, no significant association between ICS and mortality was observed among asthma patients. Conclusion: ICS is associated with increased mortality and risk for hospitalization in patients with COVID-19 as compared to standard non-steroid-based COVID-19 therapy. It is crucial for healthcare providers to carefully evaluate the potential risks and benefits of ICS usage in the context of COVID-19 management to optimize patient outcomes and safety.

Medical student perceptions of mental illness: a cross-sectional transnational study in two medical schools.

BACKGROUND: Despite shifting global attitudes, mental illness remains highly stigmatised amongst practicing doctors. This has wider implications on doctors' training to care for patients with mental illness. There is need for exploration of the presence and mitigation of stigma in early medical education to prevent such attitudes propagating into clinical practice. Thus, this study explores whether stigmatising attitudes are detectable amongst medical students in London and Singapore and examines whether they are ameliorated by specific curricular and welfare features of formal medical education, utilising the Mental Illness Stigma Framework (MISF). METHODS: A mixed-methods approach was adopted. Medical students at Imperial College London (UK; n = 211) and Nanyang Technological University (Singapore; n = 141) completed a validated scale (the OMS-HC-15) to assess attitudes towards mental illness. Semi-structured interviews were conducted (Imperial: n = 12, NTU: n = 8) until theoretical saturation was reached. Quantitative data were analysed descriptively and comparatively using SPSS and interview data subjected to inductive thematic analysis. RESULTS: Total OMS-HC-15 scores ranged from 19-51 for Imperial (n = 211) and 16-53 for NTU (n = 141). No significant differences in overall stigma scores were found between the two schools (p = 0.24), nor when comparing year groups within each school. Four themes were identified across interview data: student perceptions, impacts of medical school culture, university support, and curricular impacts on mental illness perceptions. Themes allowed identification of aspects of medical school that were well-received and warranted further emphasis by students, alongside areas for improvement. CONCLUSION: Mental health stigma was identified in two medical schools, with differing cultures. Mean stigma scores obtained were comparable between both UK and Singaporean medical students. Nuanced differences were identified via subgroup analysis, and the MISF identified both shared and country-specific drivers for this stigma across the qualitative data. Actionable recommendations to mitigate this were hypothesised. Curricular improvements such as earlier psychiatric teaching and sharing of personal stories may improve future stigma scores as students' progress through the course. Specific welfare-based changes to formal support systems were also deemed to be beneficial by students. The impacts of welfare and curricular redesign in relation to societal influence on students' attitudes warrants further investigation, as does medical students' self-stigma.

Acute Colonic Pseudo-Obstruction in an Elderly Female Patient With Chronic Constipation.

Acute colonic pseudo-obstruction (ACPO), or Ogilvie's syndrome, is an acute colonic dilatation without mechanical obstruction; it is most commonly seen in severely ill or postoperative patients. While this syndrome has no clear pathophysiology, it is diagnosed when the cecum and right colon expand without physical obstruction. This condition can lead to perforation and intestinal ischemia. Ogilvie's syndrome is associated with a relatively high morbidity and mortality rate. The diagnosis of ACPO can be often missed due to its vague symptoms such as bloating, abdominal distention, abdominal pain, nausea and vomiting, and severe constipation. We report the case of an 82-year-old female patient who had a unique diagnosis of ACPO, or Ogilvie's syndrome, overshadowed by the diagnosis of severe constipation. This case highlights the importance of maintaining a high index of suspicion and early diagnosis of symptoms that can rapidly become dangerous.

In Silico Identification of Potential Quadruplex Forming Sequences in LncRNAs of Cervical Cancer.

Long non-coding RNAs (lncRNAs) have emerged as auxiliary regulators of gene expression influencing tumor microenvironment, metastasis and radio-resistance in cancer. The presence of lncRNA in extracellular fluids makes them promising diagnostic markers. LncRNAs deploy higher-order structures to facilitate a complex range of functions. Among such structures, G-quadruplexes (G4s) can be detected or targeted by small molecular probes to drive theranostic applications. The in vitro identification of G4 formation in lncRNAs can be a tedious and expensive proposition. Bioinformatics-driven strategies can provide comprehensive and economic alternatives in conjunction with suitable experimental validation. We propose a pipeline to identify G4-forming sequences, protein partners and biological functions associated with dysregulated lncRNAs in cervical cancer. We identified 17 lncRNA clusters which possess transcripts that can fold into a G4 structure. We confirmed in vitro G4 formation in the four biologically active isoforms of SNHG20, MEG3, CRNDE and LINP1 by Circular Dichroism spectroscopy and Thioflavin-T-assisted fluorescence spectroscopy and reverse-transcriptase stop assay. Gene expression data demonstrated that these four lncRNAs can be potential prognostic biomarkers of cervical cancer. Two approaches were employed for identifying G4 specific protein partners for these lncRNAs and FMR2 was a potential interacting partner for all four clusters. We report a detailed investigation of G4 formation in lncRNAs that are dysregulated in cervical cancer. LncRNAs MEG3, CRNDE, LINP1 and SNHG20 are shown to influence cervical cancer progression and we report G4 specific protein partners for these lncRNAs. The protein partners and G4s predicted in lncRNAs can be exploited for theranostic objectives.

Between-Sex Differences in Risk Factors for Cardiovascular Disease among Patients with Myocardial Infarction-A Systematic Review.

Between-sex differences in the presentation, risk factors, management, and outcomes of acute myocardial infarction (MI) are well documented. However, as such differences are highly sensitive to cultural and social changes, there is a need to continuously re-evaluate the evidence. The present contemporary systematic review assesses the baseline characteristics of men and women presenting to secondary, tertiary, and quaternary centres with acute myocardial infarction (MI). Over 1.4 million participants from 18 studies, including primary prospective, cross sectional and retrospective observational studies, as well as secondary analysis of registry data are included in the study. The study showed that women were more likely than men to have a previous diagnosis of diabetes, hypertension, cerebrovascular disease, and heart failure. They also had lower odds of presenting with previous ischaemic heart disease and angina, dyslipidaemia, or a smoking history. Further work is necessary to understand the reasons for these differences, and the role that gender-specific risk factors may have in this context. Moreover, how these between-gender differences are implicated in management and outcomes also requires further work.

Using energy to go downhill - a genoprotective role for ATPase activity in DNA topoisomerase II.

Curiously, most type II topoisomerases (topos II, IV, and VI) catalyze DNA transformations that are energetically favorable, such as the removal of superhelical strain; why ATP is required for such reactions is unknown. Here, using human topoisomerase II ß (hTOP2ß) as a model, we show that the ATPase domains of the enzyme are not required for DNA strand passage, but that their loss leads to increased DNA nicking and double strand break formation by the enzyme.

The presence of either the CTD or the mutations lead ATPase-less enzymes to promote even greater levels of DNA cleava in ge vitro , as well as in vivo . By contrast, the aberrant cleavage phenotypes of these topo II variants is significantly repressed when the ATPase domains are restored. Our findings are consistent with the proposal that type II topoisomerases acquired an ATPase function to maintain high levels of catalytic activity while minimizing inappropriate DNA damage.

Leading Transformation in Medical Education Through Extended Reality.

Extended reality (XR) has exponentially developed over the past decades to incorporate technology whereby users can visualise, explore, and interact with 3-dimensional-generated computer environments, and superimpose virtual reality (VR) onto real-world environments, thus displaying information and data on various levels of the reality-virtuality continuum. In the context of medicine, VR tools allow for anatomical assessment and diagnosis, surgical training through lifelike procedural simulations, planning of surgeries and biopsies, intraprocedural guidance, and medical education. The following chapter aims to provide an overview of the currently available evidence and perspectives on the application of XR within medical education. It will focus on undergraduate and postgraduate teaching, medical education within Low-Middle Income Countries, key practical steps in implementing a successful XR programme, and the limitations and future of extended reality within medical education.

Prevalence of active and passive smoking among asthma and asthma-associated emergency admissions: a nationwide prevalence survey study.

Asthma affects 7% of children and 8% of adults in the United States. There is a paucity of studies examining the association between passive smoking and an increased risk of asthma exacerbations that led the authors to examine the association between various modes of smoking and rates of asthma exacerbations. A retrospective cross-sectional/case-control study was conducted using the National Health and Nutrition Examination Survey dataset (2013-2018). Out of 312,979 respondents, 35,758 (11.43%) had a history of asthma, 9083 (2.9%) had asthma attacks in the past year, and 4731 (1.51%) had asthma-related emergency room admissions in the past year. Prevalence of asthma-related emergency admissions were higher among active cigarette smoking (46.25 vs 35.46%), e-cigarette smoking (26.63 vs 16.07%), and passive smoking at home (37.53 vs 25.67%), workplace passive smoking (14.35 vs 12.11%), in bar (32.38 vs 26.16%), and car (26.21 vs 14.44%) (p < 0.0001). In multivariate regression analysis, we found regular cigarette smoking (OR 1.13, 95% confidence interval (CI) 1.009-1.260, p = 0.0252), e-cigarette (OR 2.13, 95% CI 1.92-2.36, p = 0.0043), cigar use (OR 1.21, 95% CI 1.1-1.33, p < 0.001), ultra-long cigarette length (OR 4.85, 95% CI 3.33-7.06, p < 0.0001), and passive smoking (OR 5.25, 95% CI 3.43-8.06, p < 0.0001) were associated with increased rates of asthma exacerbations over last 12 months. The study shows increased odds of asthma exacerbations among those using ultra-long cigarettes, e-cigarettes, and cigars. Consequently, passive inhalation from even a single smoker in the home, workplace, bars and cars is associated with worsening outcomes in asthma patients.
