Kidney failure amongst Irish Travellers.

BACKGROUND: The occurrence of Kidney Failure with Replacement Therapy (KFRT) amongst Irish Travellers has not been well described. This study aims to determine the burden of KFRT amongst the Irish Traveller population and identify determinants of health amongst this cohort which may differ from the general population in Ireland. METHODS: This retrospective cohort study included self-identifying Irish Travellers with KFRT registered in the National Kidney Disease Clinical Patient Management System between 1995 and 2022. KFRT was defined as Chronic Kidney Disease stage 5 (CKD G5) treated by dialysis or CKD G1-G5 after transplantation. The primary outcome measure was the prevalence of KFRT in Irish Travellers. Secondary exploratory outcomes included age at diagnosis, family history, biopsy diagnosis, kidney replacement therapy (KRT) modality, time to initiation of KRT, primary vascular access used, and time to receive a kidney transplant. RESULTS: Four of six Irish hospital groups participated in the study. A total of 38 patients were identified as Irish Travellers with KFRT, with a crude prevalence rate of KFRT of 0.12% (CI 0.084-0.161, 95%) or 11.9 per 10,000 Irish Travellers. The mean age for diagnosis of kidney disease was 43 (SD, 20.8) and at commencement of KRT was 45 (SD, 20.9) years. A biopsy-proven diagnosis was provided in 24%. Twenty-two per cent was diagnosed with polycystic kidney disease or congenital anomalies of the kidney and urinary tract. The predominant modality for KRT was haemodialysis (89%), with central venous catheters being the most common initial vascular access (79%). Kidney transplants occurred in 45% of those studied, with a mean waiting time of 1.96 (SD, 1.6) years. CONCLUSIONS: The Irish Traveller community have similar prevalence of KFRT when compared to the national prevalence, with a short time interval from diagnosis to commencement of KRT. They are less likely to avail of home therapies but have comparable wait times to the national waiting time to receive a kidney transplant.

Examination of the Knowledge Levels of Family Medicine Residents in Turkey about Oral and Dental Health.

PURPOSE: To measure the general oral and dental health knowledge level of family medicine residents who are receiving full-time specialty training in Turkey. Primary care physicians can contribute to improving the oral and dental health of patients during general health services. MATERIALS AND METHODS: The fundamentals of oral and dental health that the family medicine physicians should know about were determined, and questionnaire items on these fundamentals were prepared. The sample size was calculated as 296 individuals. The survey was conducted online. The collected data were analysed employing the following tests: chi-squared, Fisher, Kolmogorov-Smirnov, Spearman, ANOVA, Mann-Whitney U, Kruskal-Wallis, and Bonferroni. RESULTS: 302 family medicine residents in various clinics in Turkey participated in the study. The mean age of the participants was 29.6 ± 5.1. The mean knowledge scores of the resident physicians were calculated as 65.2 ± 10.9 (lowest: 27; highest: 92). The majority of resident physicians stated that they did not receive training on oral and dental health during their residency training, and that they agreed with the idea of integrating it into the residency training curriculum. CONCLUSIONS: The general knowledge level of family medicine residents in Turkey about oral and dental health was found to be moderate.

Animations to communicate public health prevention messages: a realist review protocol.

INTRODUCTION: With digital and social media advances, animated health communications (health animations) are highly prevalent globally, yet the evidence base underpinning them remains unclear and limited. While individual studies have attempted to explore the effectiveness, acceptability and usability of specific features of health animations, there is substantial heterogeneity in study design, comparators and the animation design and content. Consequently, there is a need to synthesise evidence of health animations using an approach that recognises this contextual complexity, which may affect their impact. METHODS AND ANALYSIS: This project aims to understand why, how, for whom, to what extent and in which contexts health animations are expected to promote preventive health behaviours. We will conduct a realist review following Pawson's five iterative stages to (1) define the review scope and locate existing theories; (2) search for evidence; (3) select and appraise evidence; (4) extract data and (5) synthesise data and refine theory. Engagement with stakeholders involved in developing, testing, implementing or commissioning health communications, including animations, will allow the initial programme theory to be tested and refined. The findings will be reported in accordance with Realist and Meta-narrative Evidence Syntheses: Evolving Standards. ETHICS AND DISSEMINATION: Ethical approval for the public stakeholder work was provided by the Northumbria University Research Ethics Committee. We will disseminate the findings widely through outputs tailored to target specific professional, public and patient audiences. Dissemination will occur through stakeholder engagement as part of the research, a peer-reviewed publication and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42023447127.

[Muscle pain in myositis in a young female patient: what is behind this?] / Muskelschmerzen bei Myositis bei einer jungen Patientin ­ was steckt dahinter?

Myositis is a connective tissue disease which is most frequently diagnosed in women aged 40-60 years. Due to a clear association with underlying malignant diseases, general tumor screening is recommended whenever it is diagnosed. Colorectal carcinoma (CRC) is a common malignant disease, and the typical at-risk group comprised, to date, patients older than 55 years. However, with the rising incidence of so-called early-onset colorectal carcinoma (EO-CRC), an increasingly important patient population is emerging in the 20- to 50-year age range. One reason for the rising incidence is suggested to be an increase in classic risk factors at younger ages. Here, the case of a 34-year-old female patient who presented with the leading paraneoplastic syndrome of myositis and was diagnosed with a sporadic form of CRC is reported. Monitoring of known risk factors as early on as in young adulthood and greater attention in the presence of symptoms such as gastrointestinal hemorrhage or paraneoplastic syndromes seem necessary to compensate for the time delay in diagnosis that currently still exists and the associated worse oncologic outcome.

Reproducibility of SIMPLE classification for diabetic retinopathy screening and its comparison to current Italian guidelines.

PURPOSE: To evaluate the reproducibility of SIMPLE (Single field Image Multi Parameters defined Lesions Extent), a new Diabetic Retinopathy (DR) classification for screening of 45° single field fundus pictures of patients with diabetes (PwDM), assessing DR, Diabetic Maculopathy (DMac) and referral rate agreement and comparing it to current Italian Guidelines (IG). MATERIALS AND METHODS: We conducted a retrospective, observational, multicentre study, collecting 1000 retinal 45° single field images of PwDM obtained during routine visits in two diabetes clinics. Three ophthalmologists evaluated each image, determining the presence and number of specific DR lesions and then assigning a stage according to the current IG for screening. SIMPLE staging was performed automatically via Excel software, based on the pre-specified DR characteristics observed by the graders. We analysed intra-centre, inter-centre and total inter-grader agreement for DR and DMac stage and referral rate of the two classifications. RESULTS: Agreement amongst the three graders was consistently higher when using SIMPLE classification than when using current IG classification. For DR, kappa (k) was 0.86 with IG and 0.95 with SIMPLE classification; for DMac, k-IG was 0.78, while k-SIMPLE was 0.96; concordance on the referral rate was 0.91 with IG and 0.99 with SIMPLE. Similar results were obtained in sub-analyses for the evaluation of intra-centre and inter-centre concordance. CONCLUSIONS: Our results suggest that the new SIMPLE classification has an excellent reproducibility amongst graders, comparable or superior to the current IG for DR screening proposed in 2015, improving the standardisation of the decision on referability.

Prevalence of Frank's sign in healthy young individuals, morphological characteristics, and its association with family history of chronic disease.

Frank's sign (FS, earlobe crease) is known to be associated with many chronic diseases i.e. coronary, cerebrovascular, and peripheral vascular diseases. The objective of this study is to investigate the presence and grade of FS in healthy, young-adult individuals aging between 18 and 25. Furthermore, to evaluate the relationship between FS and the chronic disease history of first-degree family members. 853 healthy people with a mean age of 20.09 years were imvolved in the research on a voluntary basis. Of 853 individuals, 85.3% (n:728) had no FS, whereas 14.7% (n:125) had. Of the 125 people observed FS, 41.6% (n:52) were female and 58.4% (n:73) were male. Of the 125 people diagnosed with FS, 32.8% (n:41) had no family history of any chronic disease, and 67.2% (n:84) had at least 1 family history of chronic disease as well. It was determined that there was a statistically significant (p < 0.05) relationship between FS identified in healthy individuals and familial chronic disease history. In this study, while no FS was observed in 85.3% of the participants, grade 1 was detected in 12.4% (n:105), grade 2a in 1.9% (n:16), grade 2b in 0.2% (n:2), and grade 3 in 0.2% (n:2). To the best of our knowledge, this study investigated the relationship between the presence and grade of FS in the healthy, young, Turkish population and the presence/absence of chronic disease in the first-degree relatives of individuals for the very first time. As a result of larger studies, being aware of the presence of FS, especially in young healthy individuals, may help predict some chronic diseases, and caution may be taken to avoid these diseases at an early age in at-risk individuals.

Detailed description of multidisciplinary prehabilitation in patients admitted to nerve sparring radical prostatectomy - A randomized feasibility study protocol.

Background: Localized prostate cancer treated with radical prostatectomy is highly effective, though severe side-effects are common after the surgery. Prehabilitation is an approach to optimize patient's physical and mental resources before surgery, to improve postoperative outcomes. The feasibility of a multi-modal home-based prehabilitation program, delivered using telehealth in patients awaiting radical prostatectomy is unknown. This paper describes the development of a prehabilitation program for patients awaiting radical prostatectomy. Method: A model by The Medical Research Council for developing and evaluating complex interventions (MRC Framework) was used in the development process. The Template for Intervention Description and Replication (TIDieR) checklist was applied for ensuring sufficient description of the interventions. A total of 40 patients will be randomized to either intervention or control group. Patients in the control group will follow standard care. The 4-week prehabilitation programme consists of exercise, pelvic floor exercise, sexual counseling, stress management and nutritional support. The interventions are home-based and delivered using telehealth. Feasibility outcomes will include recruitment, attrition rates, adherence, safety and suitability. Conclusion: We have developed a multimodal prehabilitation programme, which has the potential to bring tangible health benefits to men with prostate cancer awaiting radical prostatectomy. The results of the feasibility study will inform the design of a fully powered randomized controlled trial.

Low-dose aspirin prophylaxis to prevent hypertensive disorders of pregnancy after in vitro fertilisation: a scoping review protocol.

INTRODUCTION: Pregnancies resulting from in vitro fertilisation are associated with an increased risk of developing hypertensive disorders of pregnancy, such as preeclampsia, when compared with naturally conceived pregnancies. OBJECTIVE: The efficacy of aspirin prophylaxis to reduce the incidence of preeclampsia is well established in naturally conceived pregnancies identified as high risk for developing preeclampsia. However, the efficacy of aspirin to reduce the rate of preeclampsia for all pregnancies resulting from in vitro fertilisation remains uncertain, although in vitro fertilisation conception is a well-known risk factor for preeclampsia. Therefore, the purpose of this scoping review is to provide a comprehensive overview of the current literature regarding the use of low-dose aspirin to prevent hypertensive disorders of pregnancy after in vitro fertilisation. INCLUSION CRITERIA: This review will identify all peer-reviewed published articles including pregnant women who underwent embryo transfer after in vitro fertilisation and were prescribed low-dose aspirin to reduce the risk of hypertensive disorders of pregnancy. METHODS: We have devised a comprehensive search strategy to systematically identify pertinent studies published from January 2000 until May 2024, within the Medline (PubMed interface), Embase and Scopus databases. The search strategy is based on the keywords 'aspirin,' 'pregnancy-induced hypertension,' and ('in vitro fertilization' OR 'oocyte donation' OR 'embryo transfer' OR 'donor conception'). Two reviewers will independently screen the titles, abstracts and full-text articles to select the relevant articles, using the Covidence software. ETHICS AND DISSEMINATION: No patients are involved in this study. This study aims to be published in a peer-reviewed journal and could be presented at a conference.

Antifungal prophylaxis against invasive Candida and Aspergillus infection in adult heart transplant recipients: protocol for a systematic review and meta-analysis.

INTRODUCTION: Invasive fungal infections (IFI) can contribute to increased mortality and morbidity rates after heart transplant in adults. The most common causes are Aspergillus and Candida species. There is uncertainty on how effective antifungal prophylaxis is against Candida spp infections and limited guidance on the prevention of Aspergillus spp infections. This systematic review and meta-analysis will assess the literature to see if antifungal prophylaxis reduces the incidence of IFI after heart transplant in adults. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic reviews and Meta Analysis guidelines. A systematic search of the Cochrane Library, Web of Science, Scopus, Embase, MEDLINE, and Proquest databases will be undertaken. Reference lists of retrieved publications and conference abstracts will also be searched. Title, abstract and full-text screening will be undertaken by two reviewers. Discrepancies will be resolved by a third reviewer. Studies with paediatric patients, multi-organ transplants, or patients with a second heart transplant will be excluded, along with those who do not have clear definitions and diagnostic criteria for IFI. Risk of bias will be assessed using the Cochrane Risk of Bias 2 tool and the Risk of Bias in Non-randomised Studies of Interventions tool. A meta-analysis will be carried out, but if studies are not deemed to be sufficiently similar, only a narrative synthesis will be undertaken. ETHICS AND DISSEMINATION: Ethical approval is not required for this systematic review as primary data will not be collected. The results of the review will be disseminated through publication in an academic journal and scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42024516588.

Interactive voice response (IVR) for tobacco cessation: a systematic review.

OBJECTIVE: To summarise the uses, outcomes and implementation of interactive voice response (IVR) as a tobacco cessation intervention. DATA SOURCES: A systematic review was conducted. Searches were performed on 3 May 2023. The strategies used keywords such as "tobacco cessation", "smoking reduction" and "interactive voice recording". Ovid MEDLINE ALL, Embase, APA PsycINFO, CINAHL, Cochrane Library and Web of Science were searched. Grey literature searches were also conducted. STUDY SELECTION: Titles and abstracts were assessed by two independent reviewers. Studies were included if IVR was an intervention for tobacco cessation for adults; any outcomes were reported and study design was comparative. Any abstract included by either reviewer proceeded to full-text review. Full texts were reviewed by two independent reviewers. DATA EXTRACTION: Data were independently extracted by two reviewers using a standardised form. The Risk of Bias Tool for Randomised Trials and the Risk of Bias in Non-Randomised Studies of Interventions tools were used to assess study quality. DATA SYNTHESIS: Of 308 identified abstracts, 20 moderate-quality to low-quality studies were included. IVR was used standalone or adjunctly as a treatment, follow-up or risk-assessment tool across populations including general smokers, hospitalised patients, quitline users, perinatal women, patients with cancer and veteran smokers. Effective studies found that IVR was delivered more frequently with shorter follow-up times. Significant gaps in the literature include a lack of population diversity, limited implementation settings and delivery schedules, and limited patient and provider perspectives. CONCLUSIONS: While the evidence is weak, IVR appears to be a promising intervention for tobacco cessation. However, pilot programmes and research addressing literature gaps are necessary.

[THE ROLE OF PEDAGOGY IN THE PROFESSIONAL ACTIVITY OF A MODERN DOCTOR].

The relevance of the study of the role of pedagogical knowledge in the professional activity of a modern doctor is due to the reform of the domestic health care system and the reorientation of medical workers from the treatment of diseases to preventive medicine and the promotion of a healthy lifestyle. The purpose of the work is to consider the role of pedagogy in the professional activity of a modern doctor. The article discusses the directions of building a model of interaction between a doctor and a patient. In conclusion, it is concluded that the achievements of pedagogical science, ensuring the harmonious development of personality, are also important for their use in the practical professional activity of a modern doctor, especially from the point of view of teaching patients and educating them to self-preservation behavior. Therefore, pedagogy today plays an important role in the system of training medical personnel and acts as a subject, the study of aspects of which is aimed at integrating pedagogical knowledge into the process of training a modern doctor.

Assessment of smoking care by stroke specialists in patients with recent TIA and minor stroke: an international prospective registry-based cohort study.

OBJECTIVES: The objectives are to assess smoking abstinence and its effects on vascular risk and to report tobacco-cessation counselling and pharmacotherapy use in patients who had a recent minor stroke or transient ischaemic attack (TIA). DESIGN AND SETTING: The TIA registry.org project is a prospective, observational registry of patients with TIA and minor stroke that occurred in the previous 7 days with a 5-year follow-up, involving 61 sites with stroke specialists in 21 countries (Europe, Asia, Latin America and Middle East). Of those, 42 sites had 5-year follow-up data on more than 50% of their patients and were included in the present study. PARTICIPANTS: From June 2009 through December 2011, 3847 patients were eligible for the study (80% of the initial cohort). OUTCOMES: Tobacco counselling and smoking-cessation pharmacotherapy use in smoking patients were reported at discharge. Association between 3-month smoking status and risk of a major cardiovascular event (MACE) was analysed with multivariable Cox regression model. RESULTS: Among 3801 patients included, 835 (22%) were smokers. At discharge, only 35.2% have been advised to quit and 12.5% had smoking-cessation pharmacotherapy prescription. At 3 months, 383/835 (46.9%) baseline smokers were continuers. Living alone and alcohol abuse were associated with persistent smoking; high level of education, aphasia and dyslipidaemia with quitting. The adjusted HRs for MACE at 5 years were 1.13 (95% CI 0.90 to 1.43) in former smokers, 1.31 (95% CI 0.93 to 1.84) in quitters and 1.31 (95% CI 0.94 to 1.83) in continuers. Using time-varying analysis, current smoking at the time of MACE non-significantly increased the risk of MACE (HR 1.31 (95% CI 0.97 to 1.78); p=0.080). CONCLUSION: In the TIAregistry.org, smoking-cessation intervention was used in a minority of patients. Surprisingly, in this population in which, at 5 years, other vascular risk factors were well controlled and antithrombotic treatment maintained, smoking cessation non-significantly decreased the risk of MACE.

The CATERPILLAR-study: An assessor blinded randomized controlled trial comparing a taurolidine-citrate-heparin lock solution to a heparin-only lock solution for the prevention of central-line associated bloodstream infections in paediatric oncology patients.

BACKGROUND: Taurolidine-citrate(-heparin) lock solutions (TCHL) are suggested as a promising and safe method for the prevention of central line-associated bloodstream infections (CLABSI). AIM: To investigate the efficacy TCHL for the prevention of CrLABSI in paediatric oncology patients. METHODS: An assessor blinded randomized controlled trial at the Princess Máxima Centre for paediatric oncology, the Netherlands, was performed from 2020-2023. Paediatric oncology patients receiving a tunnelled central venous access device (CVAD) were eligible. A total of 462 patients was required to compare the TCHL to the heparin-only lock (HL). Patients were followed-up for the first 90 days after CVAD insertion. The primary outcome was the incidence of the first CLABSI from CVAD insertion until the end of follow-up. Intention-to-treat and per-protocol analyses were performed. FINDINGS: In total, 232 were randomized in the HL and 231 in the TCHL-group. A total of 47 CLABSIs were observed. The intention-to-treat analysis showed that a CLABSI was observed in 26 (11.2%) of the HL-group patients versus 21 (9.1%) of the TCHL-group patients; incidence rate ratio (IRR) of 0.81 (CI95%0.46-1.45), in favour of the TCHL-group. The per-protocol analysis showed that a CLABSI was observed in 10 (7.9%) of the HL-group patients versus 6 (4.8%) of the TCHL-group patients; IRR of 0.59 (CI95%0.21-1.62) in favour of the TCHL-group. Adverse events were more common in the TCHL-group but rarely reported. CONCLUSION: No difference was detected between the TCHL and HL in the incidence of CLABSI in paediatric oncology patients. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT05740150.

Swept-source optical coherence tomography early findings in patients with carotid artery disease.

PURPOSE: Ocular ischemic syndrome can be the first and only hint of life-threatening carotid artery disease. The early recognition of carotid stenosis-related retinal signs, as well as the comprehension of the pathophysiology behind retinal changes could become relevant for physicians to predict the risk of stroke. The aim of this study is to assess the carotid artery disease-induced early structural retinochoroidal changes by means of swept-source optical coherence tomography (SS-OCT). METHODS: A prospective observational study was conducted in 72 eyes with carotid stenosis. According to the degree of stenosis, the participants were divided into a normal group (34 eyes), a mild-moderate stenosis group (22 eyes), a severe stenosis group (16 eyes). SS-OCT and OCTA were performed to scan macular fovea. Central macular thickness (CMT), subfoveal choroidal thickness (SCT) and foveal avascular zona (FAZ) area were the major measurements for our study. RESULTS: CMT was significantly thicker in group 3 when compared to group 2 and 1. SCT was significantly thinner in group 3 vs group 1, being thicker in group 2 when compared to group 1. No significant differences were obtained when comparing FAZ in the superficial and middle capillary plexus although it was significant when comparing the FAZ in the deep capillary plexus between group 1 and 3. CONCLUSION: internal carotid artery stenosis greater than 70% leads to a significant increase in CMT and a decrease in SCT prior the development of clinical findings of ocular ischemia syndrome.

Identifying suicidal risk factors in the French Overseas Territories with multimethod psychological autopsy (AUTOPSOM): a mixed-methods study protocol.

INTRODUCTION: Understanding suicide in more isolated territories is a challenge because of the entanglement of cultural identity with historical, geographical and sociocultural specificities. This knowledge is a necessary precondition for the implementation of targeted prevention strategies in regions such as the French overseas territories (FOT), where data concerning suicidal risk factors is still incomplete. We aim to untangle sociocultural and clinical suicide risk factors by integrating a novel anthropological and psycholinguistic approach into the psychological autopsy method. This article describes the protocol of the clinical study 'Contribution of Psychological Autopsy to the Understanding of Suicidal Behaviours in Overseas France' (AUTOPSOM study), designed to identify common or new specific suicide risk factors in four FOT. METHODS AND ANALYSIS: A multicentre epidemiological study will be carried out in four FOTs (French Polynesia, Martinique, La Reunion and French Guiana) and at a comparison site in mainland France (La Somme). The methodology will be based on a mixed-methods (quantitative and qualitative) approach using a psychological autopsy to collect clinical data and life events in the deceased's life. We implemented an exploratory multimethod strategy that combines a succession of epidemiological, anthropological, psycholinguistic and psychological methods with a semiautomated analysis of the discourse of relatives bereaved by suicide. ETHICS AND DISSEMINATION: The study protocol (first version) was approved by the French Ethics Committee (CPP OUEST II, approval #22.04267.000122) and the Ethics Committee of French Polynesia (JOPF of 5 April 2022; CEPF opinion n°91 of 29 March 2022). The overall results and the perspectives established at the end of the study will be communicated to the bereaved relatives according to their will and serve for local suicide prevention purposes. TRIAL REGISTRATION NUMBER: NCT05773898.

Unlocking the combined action of Mentha pulegium L. essential oil and Thym honey: In vitro pharmacological activities, molecular docking, and in vivo anti-inflammatory effect.

Mentha pulegium L., a plant widely embraced for its therapeutic properties by populations worldwide, including Morocco, has long been recognized for its potential in treating various ailments. This study aims to comprehensively evaluate the antioxidant, anti-inflammatory, and dermatoprotective properties of essential oil derived from M. pulegium, and thyme honey as well as their combined effects. To unravel the chemical composition, a rigorous GC-MS analysis was conducted. Subsequently, we examined their antioxidant potential through three distinct assays: DPPH●, hydrogen peroxide assay, and xanthine oxidase assay. The anti-inflammatory properties were scrutinized through both in vitro and in vivo experiments. Simultaneously, the dermatoprotective efficacy was investigated in vitro by evaluating tyrosinase inhibition. Our findings revealed that pulegone constitutes the predominant compound in M. pulegium essential oil (MPEO), constituting a remarkable 74.82 % of the composition. Significantly, when the essential oil was combined with thym honey, it exhibited superior anti-inflammatory and dermatoprotective effects across all in vivo and in vitro tests. Moreover, our in silico molecular docking analysis hinted at the potential role of cyclohexanone, 3-methyl, an element found in the MPEO, in contributing to the observed outcomes. While this study has unveiled promising results regarding the combined in vitro, in vivo and in silico biological activities of the essential oil and honey, it is imperative to delve further into the underlying mechanisms through additional experimentation and alternative experimental methods. Understanding these mechanisms in greater detail will not only enhance our comprehension of the therapeutic potential but also pave the way for the development of innovative treatments and applications rooted in the synergy of these natural compounds. Furthermore, it would be advantageous to test different possible combinations using experimental design model. Moreover, it would be better to test the effect of single compounds of MPEO to clearly elucidate their efficiency. MPEO alone or combined with thyme honey may be a useful for the development of novel biopharmaceuticals.

Bridging Gaps: Analyzing Breast Imaging-Reporting and Data System (BI-RADS) 0 Rates and Associated Risk Factors in Disproportionally Affected Communities.

Introduction Disparities in access to breast cancer screening led to the creation of the Linda Fenner 3D Mobile Mammography Center (LFMMC), successfully increasing screening for uninsured women in Miami-Dade. However, a higher-than-expected rate of inconclusive mammograms (Breast Imaging-Reporting and Data System (BI-RADS) 0) was found, which could lead to unnecessary procedures, stress, costs, and radiation. Methods In this retrospective cross-sectional study, we analyzed data from 3,044 uninsured women aged over 40 (younger if positive family history of breast cancer) from Miami-Dade without breast symptoms or breast cancer history. Women's demographic characteristics, primary language spoken, body mass index (BMI), use of hormone replacement therapy and birth control, history of benign biopsy, breast surgery, family breast cancer, and menopausal status were assessed as potential risk factors for an inconclusive (BI-RADS 0) screening mammogram result. Multivariable logistic regression analyses were used to evaluate associations. Results The average age of women was 51 years (SD = 9); 59% were White, and 30% were African American. The overall frequency of BI-RADS 0 was 35%. Higher odds of BI-RADS 0 were found for women who were younger, single, premenopausal, and with benign biopsy history. Conversely, obesity and breast implant history decreased the odds of BI-RADS 0. Conclusion We found a high frequency of BI-RADS 0 in the LFMMC sample. Potential reasons include a higher risk for breast cancer or a younger sample of women screened. Future research should explore radiologists' reasoning for assigning BI-RADS 0 results and testing alternative screening strategies for younger women.

Variation of retinal and choroidal microvascularization after an exercise stress test in patients with effort angina.

PURPOSE: To describe retinal and choroidal vascular changes following an exercise stress test (ET) in patients with effort angina and to determine whether optical coherence tomography angiography (OCT-A) could play a role in the prediction of ischemic cardiac events. METHODS: Prospective comparative study including patients with effort angina. All patients underwent OCT-A before and after an ET was performed. Blood flow, intercapillary spaces, and vessel density were analyzed in the superficial capillary plexus (SCP) and the deep capillary plexus (DCP). Vessel density in the choriocapillaris and the parameters of the central avascular zone (CAZ) were also analyzed. RESULTS: Of the 38 eyes included in the study, a decrease in blood flow was found in 39.5% in the large SCP vessels, in 50% in the capillaris of the SCP, and in 81.6% in the DCP. An increase in intercapillary spaces was observed in the SCP in 68.4% of eyes and in the DCP in 55.3% of eyes. A statistically significant decrease in the DCP density was observed after an ET (p = 0.03). There were no significant modifications in the CAZ parameters, the SCP density, nor the choriocapillaris density. Patients with a positive ET had a decreased DCP density in 83.3%. Among patients with an increased DCP density, 92.85% had a negatif ET. CONCLUSION: This pilot study suggests that DCP density significantly decreases after an ET. The DCP appears to be most affected in patients with effort angina. A larger trial is needed to further investigate these hypotheses.

Extended high-frequency hearing loss among Afro-Colombian adolescents from a rural area in Colombia: a cross-sectional study.

OBJECTIVES: Research trends concerning hearing loss within teen rural populations are limited and current evidence suggests that extended high-frequency audiometry can be a sensitive tool to detect subclinical hearing loss. Moreover, current research emphasises the importance of representing different ethnic populations in science. This study aimed to determine the prevalence of acquired hearing loss through conventional pure-tone (0.25-8 kHz) and extended high frequency (EHF) (9-20 kHz) audiometry in Afro-Colombian adolescents from a rural area in Colombia. DESIGN: Observational, cross-sectional study. PARTICIPANTS: 230 Afro-Colombian adolescents aged 13-17 years who attended high school in a rural population from Cartagena, Colombia. INTERVENTIONS: Otoscopic examination, conventional (0.25-8 kHz) and EHF (9-20 kHz) audiometry tests were performed during February-March 2021. Sociodemographic and associated factor questionnaires were also applied to assess probable factors associated with EHF hearing loss. MAIN OUTCOME MEASURES: Prevalence of acquired hearing loss using conventional and EHF audiometry, and factors associated with hearing loss. RESULTS: Of 230 adolescents who met the eligibility criteria, 133 (57.82%) were female. The mean age was 15.22 years (SD: 1.62). The prevalence of hearing loss in at least one ear assessed with conventional audiometry was 21.30% and with EHF audiometry 14.78%. The main abnormal otoscopic findings included: neotympanum (1.30%), myringosclerosis (0.87%) and monomeric scars (0.43%). Factors associated with a higher probability of EHF hearing loss found through logistic regression were older age (prevalence ratio (PR): 1.45; 95% CI 1.16 to 1.80), attending the 'Picó' four or more times a month (PR: 6.63; 95% CI 2.16 to 20.30), attending bars more than three times a month (PR: 1.14; 95% CI 1.03 to 1.59) and self-reported hearing difficulties (PR: 1.24; 95% CI 1.22 to 4.05). CONCLUSIONS: Our results suggest that acquired hearing loss is already widespread among this young rural population.
