This study aimed to compare PRAAN’s accuracy to that of spirometry and the mini-Wright peak flow meter for PEFR measurement. Methods Two cross-sectional studies were conducted in 106 healthy adult participants. Study A (n=56) compared PRAAN with spirometry, while study B (n=50) compared PRAAN with the mini-Wright peak flow meter. PEFR values were collected using crossover studies. Pearson’s correlation and Bland-Altman plots were used to report the relationship and agreement between two measurements, respectively. Results In study A, 51.8% were female, mean age was 24.3±5.6 years, and PEFR was 480.3±86.8 L/min. PEFR measured by PRAAN had very strongly positive correlation with spirometry (r=0.980, P<0.001). Bland-Altman analysis showed that there was good agreement between them, with a low mean difference of -7.07 liters/minute (95% CI: -40.58 to 26.44 liters/minute) and 92.9%, which were within the limit of agreement (LOA). In study B, 54.0% were female, mean age was 23.5±2.4 years, and PEFR was 495.1±82.7 L/min. PEFR measured by PRAAN and by the mini-Wright peak flow meter showed very strongly positive correlation (r=0.971, P<0.001). Bland-Altman comparison of PEFR between these two measurements showed that there was a very good agreement between them, with a low mean difference of 0.84 liters/minute (95% CI: -38.68 to 40.38 liters/minute) and 94.0%, which were within LOA. Conclusions The accuracy of PRAAN is in the agreement with spirometry and the mini-Wright peak flow meter. The clinical application of PRAAN may potentially lead to a monitoring strategy that healthcare providers can use to improve the management of asthma.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ramasu, Grace Kanakana-Katumba","doi":"10.12688/f1000research.152478.1","DOIUrl":"https://doi.org/10.12688/f1000research.152478.1","url":null,"abstract":"Background This research investigated the dynamics of fee-free higher education in South Africa, aiming to elucidate the complexities surrounding its implementation and impact. By employing a causal loop diagram approach, the study examined the interplay of socioeconomic, political, and institutional factors influencing the provision of fee-free higher education. Method A participatory approach to developing the CLD was used. Through an extensive literature review, the research contextualised fee-free higher education enabling a preliminary CLD to be developed. Discussions were held to improve the preliminary model based on stakeholder and expert opinion. The model was then validated by stakeholders and experts. Results The CLD has explicitly mapped out the causal relationships which play a fundamental role in fee-free higher education in South Africa. Key findings revealed that fee-free higher education initiatives, such as managing funding constraints and administrative complexities, hold promise for fostering inclusivity and socioeconomic development but are hindered by bureaucratic policy establishments and inefficiencies. These challenges underscore the gap between policy formulation and implementation, highlighting the need for comprehensive reforms to streamline administrative processes and enhance financial sustainability within the higher education sector. Conclusion This research thoroughly examined the dynamics of fee-free higher education in South Africa, highlighting both the challenges and opportunities in its implementation. The study emphasized the need for systemic reforms to improve accessibility and effectiveness, while also underscoring the potential of such initiatives to promote social mobility and economic empowerment, aligning with global goals like the SDGs and the African Agenda 2063.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Otherwise it can lead to weakness in vocal cord function if ligated along with the arteries during thyroidectomy or other surgical procedures. The aim of our study was to examine and document the origin, relationship, and branching patterns of the laryngeal nerves on the side of the neck. Method The present cross sectional anatomical study was conducted on 64 dissected necks of formalin-fixed cadavers that were utilized for undergraduate teaching purposes. Different parameters were measured in the neck along with the relationship between the laryngeal nerves and their accompanying arteries. Results We observed usual and unusual course of laryngeal nerves along with some variations. Some of the novel findings were an internal laryngeal nerve piercing the thyroid cartilage lamina and an external laryngeal nerve communicating with the superior cervical ganglion. Conclusion The present study observed anatomical variations in the course of the laryngeal nerves, which are relevant for clinical practice. The potential risks of damage to these laryngeal nerves during various surgical procedures make it necessary to review and compile its relationship with the surrounding structures.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141666769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An early adolescence male, after recent corneal tear repair, presented acute eye pain, redness, and decreased vision for 1 day. He underwent corneal tear repair elsewhere post vegetative matter-related swimming injury. Ophthalmic examination revealed a 2.5*3.3mm ulcer around sutures. Corneal scrapings enabled microscopy and culture. With lesion worsening, tissue adhesive (TA) and bandage contact lens (BCL) were applied. Fungal culture identified Medicopsis romeroi. Patient's history, clinical course, and treatment were documented. Microscopy unveiled fungal hyphae, later confirmed as Medicopsis romeroi. Treatment included topical/systemic antifungals. Post-TA + BCL, significant improvement followed, with re-epithelialization, scarring. This report underscores the importance of considering rare fungal pathogens like Medicopsis romeroi in cases of corneal ulcers, especially in individuals with unusual risk factors. Timely diagnosis through microscopy and fungal culture, coupled with tailored antifungal treatment led to successful management and favorable patient outcomes. This case also emphasizes the significance of vigilant clinical observation, precise laboratory analysis, and multidisciplinary collaboration between ophthalmologists and microbiologists in managing atypical ocular infections.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many factors that influence people with HTN to develop cardiovascular disease, such as lifestyle, genetics, economics, overall health, and medications; the authors did not find any previous study employing Multi-Attribute Utility Theory (MAUT) analysis using machine learning. There is a sense of urgency to understand the characteristics of HTN patients in Pakistan; by using MAUT to analyze and evaluate different factors related to developing HTN, we can gain valuable insights into the characteristics of HTN and cardiovascular HTN (HTN-CVD) patients in Pakistan. Methods and results This study utilized a cross-sectional survey with 98 participants diagnosed with HTN and HTN-CVD. The questionnaire included sociodemographic items, symptoms, heredity factors, and dietary habits. The study was approved by the Research Ethical Committees of Pir Mehr Ali Shah Arid Agriculture University Rawalpindi (PMAS-AAUR), Pakistan. The result shows that there is a wide difference between HTN and HTN-CVD patients’ scores for symptoms (37% vs. 63%) and economic status (39% vs. 61%) (respectively). Other than these, the attribute proportions of scores for HTN and HTN-CVD are almost the same. The highest MAUT scores were higher for patients with HTN-CVD (373) than for those with HTN alone (270), and the mean age of HTN patients is higher than HTN-CVD; almost all attributes’ groups of the 10 highest MAUT scores of HTN-CVD higher than HTN patients except for attribute of medication status. Conclusion Patients with HTN-CVD complications have higher MAUT scores for lifestyle, social status, health status, and economic status. This emphasizes the importance of educating patients (and indeed the general public) about risks, symptoms, and adopting healthy behaviors.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141667640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study is aimed at evaluating the correlation between the lipiodol retention of the tumor with a complete response after cTACE and tumor recurrence by quantitative assessment. Methods From January 2013 to September 2023, every patient receiving cTACE for HCC was recognized. Inclusion criteria were patients with ≤6 HCCs and sizes 1-6 cm, with at least one tumor obtaining a complete response after cTACE, and available baseline and follow-up CT studies. Tumoral, cTACE procedural, and lipiodol staining parameters were analyzed. Using univariate and multivariate analysis, significant factors associated with tumor recurrence were identified. ROC curve analysis was used to identify the optimal cutoff point for the statistically significant factors, predicting tumor recurrence. Results The final population included 39 patients with 63 HCCs. Tumor recurrence was detected in 18/63 (28.6%) at a mean of 27.8 months. On univariate analysis, the incidence of tumor recurrence significantly increased with increased tumor size (p = 0.007), an inhomogeneous lipiodol staining pattern (p<0.001), a low minimum lipiodol radiodensity (p = 0.012), and a high lipiodol washout rate (p = 0.046). On multivariate analysis, an inhomogeneous lipiodol staining pattern (p<0.001) and a high lipiodol washout rate (p = 0.012) were significant predictors for tumor recurrence. On ROC analysis, a lipiodol washout rate of greater than 6.44 HU/month was related to tumor recurrence (sensitivity 83%, specificity 51%). Conclusions Inhomogeneous lipiodol staining pattern and lipiodol washout rate of >6.44 HU/month were predictors for recurrence of HCC after a complete response after cTACE. These correlations may provide useful guidance for subsequent imaging surveillance and treatment approaches.","PeriodicalId":12260,"journal":{"name":"F1000Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite level A evidence for migraine prevention, biofeedback treatment is still unavailable to most patients. We developed a novel medical device (Cerebri) for multimodal biofeedback treatment that omits the need for healthcare personnel involvement. Cerebri consists of a smartphone application (app) and two wireless sensors. Unique in its approach, the Cerebri app seamlessly integrates three biofeedback modalities – heart rate variability, temperature, and electromyography – making it a comprehensive, therapist-independent solution for non-pharmacological migraine management. Methods Biofeedback therapy using Cerebri for the prevention of migraine attacks in adults with episodic migraine (The BioCer study) was an open-label, randomized, waitlist-controlled, multicenter trial. This study investigated the safety and efficacy of daily home-based biofeedback sessions using the Cerebri device. A total of 286 participants will be randomized to either a 12-week intervention arm or waitlist control arm. The primary outcome was the change in the mean number of migraine days from baseline to the last 28-day period during the treatment phase in the treatment group compared with the control group. The primary outcome variable was prospectively collected through daily eDiary entries. Ethics and Dissemination Approval from the ethics committee and competent authorities was obtained prior to study initiation.
