Delphi Analysis: Optimizing Anatomy Teaching and Ultrasound Training for Botulinum Neurotoxin Type A Injection in Spasticity and Dystonia

Our objective was to provide expert consensus on best practices for anatomy teaching and training on ultrasound-guided botulinum neurotoxin type A (BoNT-A) injection for specialists involved in treating spasticity and dystonia. Nine experts (three neurologists; six physical medicine and rehabilitation physicians) participated in a three-round modified Delphi process. Over three rounds, experts reached consensus on 15 of 16 statements describing best practices for anatomy and BoNT-A injection training. They unanimously agreed that knowledge of the target audience, including their needs and current competency, is crucial when designing training programs. Experts also agreed that alignment between instructors is essential to ensure consistency of approach over time and between regions, and that training programs should be simple, adaptable, and "hands-on" to enhance engagement and learning. Consensus was also reached for several other key areas of training program development. The best-practice principles identified by expert consensus could aid in the development of effective, standardized programs for anatomy teaching and BoNT-A injection training for the purposes of treating spasticity and dystonia. This will enhance the exchange of knowledge, skills, and educational approaches between global experts, allowing more specialists to treat important movement disorders and ultimately improving patient outcomes.

Early Detection and Noninvasive Staging of Kidney Dysfunction by a PEGylated Conventional Fluorophore via GFR-Sensitive Renal Transport

Noninvasive fluorescence imaging of renal function is a valuable technique for understanding kidney disease progression and the development of renal medicine. This technique requires sensitive imaging probes for reporting renal dysfunction accurately at early stage. Herein, a molecularly engineered imaging probe (800CW-PEG45-COOH) was synthesized by simply PEGylating conventional near-infrared fluorophore IRDye800CW with NH2-PEG45-COOH (molecular weight ∼2100 Da) for early detection and staging of renal dysfunction through noninvasive real-time kidney imaging. 800CW-PEG45-COOH not only cleared through the kidney efficiently (>90% injection dosage at 24 h postinjection) but was also found to be freely filtered by glomeruli without renal tubular reabsorption and secretion. Despite this simple construction strategy, the transport of 800CW-PEG45-COOH within the kidneys was extremely sensitive to the alteration of the glomerular filtration rate (GFR), which enabled it to detect renal dysfunction much earlier than commonly used serum biomarkers and stage kidney function impairments (mild vs severe dysfunction) via imaging-based kidney clearance kinetics. This work not only provides a promising optical imaging probe for the noninvasive evaluation of kidney function but also highlights the utility of PEGylation in enhancing the performance of conventional organic dyes in biomedical applications.

Retrospective Longitudinal Observational Study on the Long-Term Effects of Sodium-Glucose Cotransporter-2 Inhibitors on the Development of Metabolic Dysfunction-Associated Steatotic Liver Disease in Type 2 Diabetic Japanese Patients

Background/Objectives: The health burden of metabolic dysfunction-associated fatty liver disease (MASLD) has been increasing lately. Cardiovascular disease (CVD) is the main cause of death in MASLD patients; therefore, the treatments for MASLD should improve both CV risk factors such as obesity, diabetes, and dyslipidemia, in addition to an improvement in liver function. The evidence on the long-term effects of sodium-glucose cotransporter 2 inhibitors (SGLT2is) on the progression of MASLD in Asian populations is very limited. Methods: The retrospective longitudinal study was performed by using the medical records at our institute. We picked up patients with type 2 diabetes who had taken SGLT2is for at least 3 years or longer between 1 April 2014 and 31 March 2018. We collected the data on metabolic parameters, including laboratory data and anthropometric parameters, and compared the data before and after the initiation of SGLT2is treatment. Results: During the observation period, 324 patients had taken SGLT2is for 3 years. Three-year SGLT2is treatment significantly reduced body weight, hemoglobin A1c, low-density lipoprotein cholesterol, triglyceride, and non-high-density lipoprotein cholesterol (non-HDL-C). Such favorable changes in serum lipids were remarkable in patients with statins. Furthermore, this treatment significantly improved liver function and the markers for hepatic steatosis and hepatic fibrosis. Conclusions: Considering that the development of CVD determines the prognosis of MASLD patients, long-term SGLT2is treatment may be an ideal therapy for MASLD patients.

Prerequisites for Clinical Implementation of Whole-Heart 4D-Flow MRI: A Delphi Analysis

Whole-heart 4D-flow MRI is a valuable tool for advanced visualization and quantification of blood flow in cardiovascular imaging. Despite advantages over 2D-phase-contrast flow, clinical implementation remains only partially exploited due to many hurdles in all steps, from image acquisition, reconstruction, postprocessing and analysis, clinical embedment, reporting, legislation, and regulation to data storage. The intent of this manuscript was 1) to evaluate the extent of clinical implementation of whole-heart 4D-flow MRI, 2) to identify hurdles hampering clinical implementation, and 3) to reach consensus on requirements for clinical implementation of whole-heart 4D-flow MRI. This study is based on Delphi analysis. This study involves a panel of 18 experts in the field on whole-heart 4D-flow MRI. The experience with and opinions of experts (mean 13 years of experience, interquartile range 6) in the field were aggregated. This study showed that among experts in the cardiovascular field, whole-heart 4D-flow MRI is currently used for both clinical and research purposes. Overall, the panelists agreed that major hurdles currently hamper implementation and utilization. The sequence-specific hurdles identified were long scan time and lack of standardization. Further hurdles included cumbersome and time-consuming segmentation and postprocessing. The study concludes that implementation of whole-heart 4D-flow MRI in clinical routine is feasible, but the implementation process is complex and requires a dedicated, multidisciplinary team. A predefined plan, including risk assessment and technique validation, is essential. The reported consensus statements may guide further tool development and facilitate broader implementation and clinical use. LEVEL OF EVIDENCE: NA TECHNICAL EFFICACY: Stage 5.

Impact of obesity on survival outcomes of women with advanced epithelial ovarian cancer in Lagos, Nigeria: a retrospective cohort study

Background

Epithelial ovarian cancer (EOC) is a major contributor to cancer-related illness and death among women worldwide. Obesity, a prevalent condition in many populations, has been implicated as a risk factor for various malignancies including EOC.

Objectives

This study investigated the impact of obesity on survival outcomes among women with advanced EOC in Lagos, Nigeria.

Methods

We conducted a retrospective analysis of patient medical records from a major gynaecological cancer unit of a teaching hospital in Lagos, Southwest Nigeria, to examine the relationship between body mass index (BMI) 30 kg/m2 as a measure of obesity, and progression-free (PFS) and overall survival (OS). We used Kaplan-Meier analysis stratified by patients' BMI categories (obese versus non-obese) and compared using the Log Rank test to estimate PFS and OS. The multivariable Cox proportional hazard model was used to estimate hazard ratios (HR) of the associations between the BMI categories and survival outcomes while adjusting for all confounding clinicopathologic variables. Hypothesis tests were conducted using a two-tailed approach with a significance level of 5%.

Results

Our study showed no statistically significant association between obesity and PFS (adjusted HR = 0.62, 95% confidence interval = 0.36-1.06, p = 0.282). However, a significant association was observed between obesity with or without ascites and OS (adjusted HR = 3.58, 95% confidence interval 1.28-10.02, p = 0.015).

Conclusion

Our findings suggest that obesity negatively impacts OS in patients with EOC, thus highlighting the need to address obesity in the management of EOC by introducing comprehensive, multidisciplinary approaches incorporating weight management and personalized treatment strategies to enhance the prognosis of these patients.

Non-human primate model of long-COVID identifies immune associates of hyperglycemia

Hyperglycemia, and exacerbation of pre-existing deficits in glucose metabolism, are manifestations of the post-acute sequelae of SARS-CoV-2. Our understanding of metabolic decline after acute COVID-19 remains unclear due to the lack of animal models. Here, we report a non-human primate model of metabolic post-acute sequelae of SARS-CoV-2 using SARS-CoV-2 infected African green monkeys. Using this model, we identify a dysregulated blood chemokine signature during acute COVID-19 that correlates with elevated and persistent hyperglycemia four months post-infection. Hyperglycemia also correlates with liver glycogen levels, but there is no evidence of substantial long-term SARS-CoV-2 replication in the liver and pancreas. Finally, we report a favorable glycemic effect of the SARS-CoV-2 mRNA vaccine, administered on day 4 post-infection. Together, these data suggest that the African green monkey model exhibits important similarities to humans and can be utilized to assess therapeutic candidates to combat COVID-related metabolic defects.

COVID-19-Related Cholangiopathy: Histological Findings

Cholangiopathy has been described in survivors of severe COVID-19, presenting significant clinical parallels to the pre-pandemic condition of secondary sclerosing cholangitis in critically ill patients (SSC-CIP). We aimed to examine the liver histopathology of individuals with persistent cholestasis after severe COVID-19.

METHODS

We subjected post-COVID-19 cholestasis liver samples to routine staining techniques and cytokeratin 7 immunostaining and semi-quantitatively analyzed the portal and parenchymal changes.

RESULTS

All ten patients, five men, had a median age of 56, an interquartile range (IQR) of 51-60, and required intensive care unit and mechanical ventilation. The median and IQR liver enzyme concentrations proximal to biopsy were in IU/L: ALP 645 (390-1256); GGT 925 (664-2169); ALT 100 (86-113); AST 87 (68-106); and bilirubin 4 (1-9) mg/dL. Imaging revealed intrahepatic bile duct anomalies and biliary casts. We performed biopsies at a median of 203 (150-249) days after molecular confirmation of infection. We found portal and periportal fibrosis, moderate-to-severe ductular proliferation, and bile duct dystrophy in all patients, while we observed hepatocyte biliary metaplasia in all tested cases. We observed mild-to-severe parenchymal cholestasis and bile plugs in nine and six cases. We also observed mild swelling of the arteriolar endothelial cells in five patients. We observed a thrombus in a small portal vein branch and mild periductal fibrosis in one case each. One patient developed multiple small biliary infarctions. We did not observe ductopenia in any patient.

CONCLUSIONS

The alterations were like those observed in SSC-CIP; however, pronounced swelling of endothelial cells, necrosis of the vessel walls, and thrombosis in small vessels were notable.

Assessment and monitoring of lung disease in patients with severe alpha 1 antitrypsin deficiency: a european delphi consensus of the EARCO group

BACKGROUND

Currently, there is conflicting information and guidance on the effective management of Alpha 1 Antitrypsin Deficiency (AATD). Establishing a consensus of assessment and disease management specific to AATD is important for achieving a standardized treatment pathway and for improving patient outcomes. Here, we aim to utilize the Delphi method to establish a European consensus for the assessment and management of patients with severe AATD.

METHODS

Two rounds of a Delphi survey were completed online by members of the European Alpha-1 Research Collaboration (EARCO). Respondents were asked to indicate their agreement with proposed statements for patients with no respiratory symptoms, stable respiratory disease, and worsening respiratory disease using a Likert scale of 1-7. Levels of agreement between respondents were calculated using a weighted average.

RESULTS

Round 1 of the Delphi survey was sent to 103 members of EARCO and 38/103 (36.9%) pulmonologists from across 15 countries completed all 109 questions. Round 2 was sent to all who completed Round 1 and 36/38 (94.7%) completed all 79 questions. Responses regarding spirometry, body plethysmography, high-resolution computed tomography, and the initiation of augmentation therapy showed little variability among physicians, but there was discordance among other aspects, such as the use of low-dose computed tomography in both a research setting and routine clinical care.

CONCLUSIONS

These results provide expert opinions for the assessment and monitoring of patients with severe AATD, which could be used to provide updated recommendations and standardized treatment pathways for patients across Europe.

Capsaicin Reduces Obesity by Reducing Chronic Low-Grade Inflammation

Chronic low-grade inflammation (CLGI) is associated with obesity and is one of its pathogenetic mechanisms. Lipopolysaccharide (LPS), a component of Gram-negative bacterial cell walls, is the principal cause of CLGI. Studies have found that capsaicin significantly reduces the relative abundance of LPS-producing bacteria. In the present study, TRPV1-knockout (TRPV1-/-) C57BL/6J mice and the intestinal epithelial cell line Caco-2 (TRPV1-/-) were used as models to determine the effect of capsaicin on CLGI and elucidate the mechanism by which it mediates weight loss in vivo and in vitro. We found that the intragastric administration of capsaicin significantly blunted increases in body weight, food intake, blood lipid, and blood glucose in TRPV1-/- mice fed a high-fat diet, suggesting an anti-obesity effect of capsaicin. Capsaicin reduced LPS levels in the intestine by reducing the relative abundance of Proteobacteria such as Helicobacter, Desulfovibrio, and Sutterella. Toll-like receptor 4 (TLR4) levels decreased following decreases in LPS levels. Then, the local inflammation of the intestine was reduced by reducing the expression of tumor necrosis factor (TNF)-α and interleukin (IL)-6 mediated by TLR4. Attenuating local intestinal inflammation led to the increased expression of tight junction proteins zonula occludens 1 (ZO-1) and occludin and the restoration of the intestinal barrier function. Capsaicin increased the expression of ZO-1 and occludin at the transcriptional and translational levels, thereby increasing trans-endothelial electrical resistance and restoring intestinal barrier function. The restoration of intestinal barrier function decreases intestinal permeability, which reduces the concentration of LPS entering the circulation, and reduced endotoxemia leads to decreased serum concentrations of inflammatory cytokines such as TNF-α and IL-6, thereby attenuating CLGI. This study sheds light on the anti-obesity effect of capsaicin and its mechanism by reducing CLGI, increasing our understanding of the anti-obesity effects of capsaicin. It has been confirmed that capsaicin can stimulate the expression of intestinal transmembrane protein ZO-1 and cytoplasmic protein occludin, increase the trans-epithelial electrical resistance value, and repair intestinal barrier function.

Geriatric cutaneous leishmaniasis: a retrospective analysis of 622 cases

BACKGROUND

Cutaneous leishmaniasis (CL) is most common in childhood because children are exposed to the parasite early and, unlike adults, do not have immunity to CL. Since CL is less common in geriatric patients, clinical and epidemiological data in this age group are limited. This study aims to compare the clinical and demographic characteristics of geriatric patients diagnosed with CL with young patients.

METHODS

In this retrospective study, 622 patients aged 65 and over and 6350 patients aged 19-64, who applied to Şanlıurfa Oriental Boil Diagnosis and Treatment Center between January 2013 and February 2024 and were diagnosed with CL by parasitological examination, were included. Clinical and demographic characteristics of patients diagnosed with CL, such as age, gender, location of the lesion, lesion size, duration of the lesion, and treatments applied due to the diagnosis of CL, were recorded. Clinical and demographic characteristics of geriatric and young patients were compared.

RESULTS

The mean age of elderly CL cases was 72.95 ± 6.54 years, and 65.2% were female. The most common clinical forms were ulcers (51.9%) and plaques (41%), respectively, in young and elderly patients. The most common locations of the lesions were upper limbs (54.8%) in all patients. The most preferred treatment method was intralesional (IL) meglumine antimoniate (MA) treatment (98.3%) in all patients. There were no difference between young and elderly CL cases in terms of mean number of lesions, average lesion duration, average lesion size, lesion location, clinical forms of lesions, and treatments options (P > 0.05).

CONCLUSIONS

Based on the results of our study, it can be said that the clinical and demographic characteristics of CL are similar in young and old patients and systemic MA treatment shows similar clinical benefit in both age groups. In addition, it can be said that systemic MA therapy can be used safely in young patients and elderly patients without contraindications. IL MA therapy can be used in elderly patients where systemic MA therapy is contraindicated.

The Impact of Artificial Intelligence-Assisted Learning on Nursing Students' Ethical Decision-making and Clinical Reasoning in Pediatric Care: A Quasi-Experimental Study

The integration of artificial intelligence such as ChatGPT into educational frameworks marks a pivotal transformation in teaching. This quasi-experimental study, conducted in September 2023, aimed to evaluate the effects of artificial intelligence-assisted learning on nursing students' ethical decision-making and clinical reasoning. A total of 99 nursing students enrolled in a pediatric nursing course were randomly divided into two groups: an experimental group that utilized ChatGPT and a control group that used traditional textbooks. The Mann-Whitney U test was employed to assess differences between the groups in two primary outcomes: (a) ethical standards, focusing on the understanding and applying ethical principles, and (b) nursing processes, emphasizing critical thinking skills and integrating evidence-based knowledge. The control group outperformed the experimental group in ethical standards and demonstrated better clinical reasoning in nursing processes. Reflective essays revealed that the experimental group reported lower reliability but higher time efficiency. Despite artificial intelligence's ability to offer diverse perspectives, the findings highlight that educators must supplement artificial intelligence technology with strategies that enhance critical thinking, careful data selection, and source verification. This study suggests a hybrid educational approach combining artificial intelligence with traditional learning methods to bolster nursing students' decision-making processes and clinical reasoning skills.

Impact of Breast Cancer on Cardiometabolic Health in Spanish Women ≥50 Years with Pre-Existing Type 2 Diabetes Mellitus

During breast cancer (BC), cardiometabolic disorders can worsen prognosis, particularly in women with type 2 diabetes mellitus (T2DM). This study aimed to determine the impact of BC diagnosis on cardiometabolic parameters and the incidence of complication in women over 50 years of age (90% aged ≥ 65 years) with pre-existing T2DM. Using primary care registries from Asturias (Spain), a total of 106 women diagnosed with T2DM followed by BC were selected and matched with women with T2DM (n = 212) in a cohort study. Indicators of cardiometabolic health and microvascular complications associated with T2DM were collected. Women were monitored from two years prior to five years after BC diagnosis. Conditional logistic regressions were used to compare the adjusted odds of staying below each indicator's threshold. During follow-up, women with T2DM+BC had a higher risk of fasting blood glucose ≥126 mg/dL (adjusted odds ratio [aOR] = 1.83; 95% confidence interval [CI95%]: 1.01-3.32) and glycosylated hemoglobin (Hb1Ac) ≥ 48 mmol/mol or 6.5% (aOR: 2.44; IC95%: 1.21-4.91). There was no difference between the groups regarding the incidence of microvascular complications. BC incidence negatively impacted the glycemic control of Spanish women with pre-existing T2DM measured by basal blood glucose and HbA1c, but not cardiometabolic health indicators or T2DM complications.

Design and Proof of Concept of a Web-Based Questionnaire to Identify Patients at Risk for HIV and HCV Infection

Despite remarkable improvement in the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) care continuum, the rate of late diagnosis of HIV and HCV in high-income countries remains unacceptably high. Testing relies mainly on primary care physicians' identification of risk factors. We aimed to adapt an analogic to an online questionnaire to help HIV and HCV screening and perform a pilot study to assess its accuracy and acceptability. We used the Delphi method to adapt a previously validated analogical questionnaire to a user-friendly online tool. It aimed to identify participants who should be screened for HIV or HCV and those who should be referred for pre-exposure prophylaxis (PrEP). We then designed a proof-of-concept pilot study from July to October 2022 to test its feasibility and suitability for use on a larger scale and to assess its accuracy in identifying patients at risk for HIV or HCV or with indication for PrEP. The final questionnaire consisted of 37 questions. A total of 142 participants provided informed consent, and 102 completed the questionnaire: 41 random patients recruited at the primary care level, 10 participants recently diagnosed with HIV, 20 participants with HIV on follow-up, 21 participants from the PrEP program, and 10 patients diagnosed with HCV. The tool adequately indicated the need for testing in more than 98% of participants with confirmed HIV/HCV infections or in the PrEP program. Furthermore, it adequately assessed PrEP referral in 94% of participants already on PrEP or with known HIV infection. Participants were highly satisfied with the tool, and 98% of them recommended its use. A self-administered web-based tool to identify patients who should be tested for HIV or HCV or referred to PrEP could simplify patient selection and help reduce late diagnosis.

Lung cancer (internet-based) Delphi (LUCiD): A modified eDelphi consensus process to establish Australasian clinical quality indicators for thoracic cancer

BACKGROUND AND OBJECTIVE

Approximately 16,000 new cases of lung cancer are diagnosed each year in Australia and Aotearoa New Zealand, and it is the leading cause of cancer death in the region. Unwarranted variation in lung cancer care and outcomes has been described for many years, although clinical quality indicators to facilitate benchmarking across Australasia have not been established. The purpose of this study was to establish clinical quality indicators applicable to lung and other thoracic cancers across Australia and Aotearoa New Zealand.

METHODS

Following a literature review, a modified three round eDelphi consensus process was completed between October 2022 and June 2023. Participants included clinicians from all relevant disciplines, patient advocates, researchers and other stakeholders, with representatives from all Australian states and territories and Aotearoa New Zealand. Consensus was set at a threshold of 70%, with the first two rounds conducted as online surveys, and the final round held as a hybrid in person and virtual consensus meeting.

RESULTS

The literature review identified 422 international thoracic oncology indicators, and a total of 71 indicators were evaluated over the course of the Delphi consensus. Ultimately, 27 clinical quality indicators reached consensus, covering the continuum of thoracic oncologic care from diagnosis to first line treatment. Indicators benchmarking supportive care were poorly represented. Attendant numeric quality standards were developed to facilitate benchmarking.

CONCLUSION

Twenty-seven clinical quality indicators relevant to thoracic oncology care in Australasia were developed. Real world implementation will now be explored utilizing a prospective dataset collected across Australia.

Shockwave Intravascular Lithotripsy Use in the Femoro-Popliteal Segment: Considerations From an Expert Pan-European Panel Regarding Best-Care Practice

PURPOSE

Produce expert recommendations regarding the optimal use of Shockwave intravascular lithotripsy (IVL) when treating femoro-popliteal steno-occlusive peripheral artery disease (PAD), guiding operators to use Shockwave IVL.

MATERIALS AND METHODS

A modified 3-step Delphi process was used to gain consensus surrounding preoperative/intraoperative/postoperative considerations when using Shockwave IVL for femoro-popliteal PAD. This included a structured survey, focus-group (with qualitative thematic analysis of views expressed), and final confirmatory round; participants were recruited across Europe including the United Kingdom/Switzerland.

RESULTS

Following a review to inform an online survey, 25 experts took part in a survey (5 European countries, 2023), followed by a focus-group (15 participants), 9 interviews, and final confirmatory round. A list of recommendations was prepared where at least moderate-level or high-level agreement was reached (≥70% participants agreeing). The recommendations relate to the optimal preoperative imaging, preoperative preparation(s), intraoperative imaging and use of adjuncts, as well as postoperative course, when using Shockwave IVL.

CONCLUSION

A list of expert recommendations is provided guiding the optimal use of Shockwave IVL in femoro-popliteal PAD. This will help operators achieve better clinical outcomes.

CLINICAL IMPACT

This pan-European panel of experts using intravascular lithotripsy in routine peripheral arterial disease endovascular practice has provided important insights into best care practices before, during, and after such procedures. Several recommendations have been produced based on a structured consensus process to guide clinicians globally. This will improve and standardise the use of this technology in the femoro-popliteal arterial segment.

Preclinical Evaluation of Sodium Butyrate's Potential to Reduce Alcohol Consumption: A Dose-Escalation Study in C57BL/6J Mice in Antibiotic-Enhanced Binge-Like Drinking Model

INTRODUCTION

In our earlier efforts to establish gut-brain axis during alcohol use disorder (AUD), we have demonstrated that supplementation of C57BL/6J male mice with 8 mg/mL sodium butyrate, a major short-chain fatty acid, in drinking water reduced ethanol intake and neuroinflammatory response in antibiotic (ABX)-enhanced voluntary binge-like alcohol consumption model, drinking in the dark (DID).

METHODS

To further evaluate the preclinical potential of SB, we have set a dose-escalation study in C57BL/6J male mice to test effects of ad libitum 20 mg/mL SB and 50 mg/mL SB and their combinations with ABX in the DID procedure for 4 weeks. Effects of these SB concentrations on ethanol consumption and bodily parameters were determined for the duration of the treatments. At the end of study, blood, liver, and intestinal tissues were collected to study any potential adverse effects ad to measure blood ethanol concentrations.

RESULTS

Increasing SB concentrations in the drinking water caused a loss in the protective effect against ethanol consumption and produced adverse effects on body and liver weights, reduced overall liquid intake. The hypothesis that these effects were due to aversion to SB smell/taste at these high concentrations were further tested in a follow up proof-of-concept study with intragastric gavage administration of SB. The higher gavage dose (320 mg/kg) caused reduction in ethanol consumption without any adverse effects.

CONCLUSION

Overall, these findings added more support for the therapeutic potential of SB in management of AUD, given a proper form of administration.

Malnutrition and Allergies: Tipping the Immune Balance towards Health

Malnutrition, which includes macro- and micronutrient deficiencies, is common in individuals with allergic dermatitis, food allergies, rhinitis, and asthma. Prolonged deficiencies of proteins, minerals, and vitamins promote Th2 inflammation, setting the stage for allergic sensitization. Consequently, malnutrition, which includes micronutrient deficiencies, fosters the development of allergies, while an adequate supply of micronutrients promotes immune cells with regulatory and tolerogenic phenotypes. As protein and micronutrient deficiencies mimic an infection, the body's innate response limits access to these nutrients by reducing their dietary absorption. This review highlights our current understanding of the physiological functions of allergenic proteins, iron, and vitamin A, particularly regarding their reduced bioavailability under inflamed conditions, necessitating different dietary approaches to improve their absorption. Additionally, the role of most allergens as nutrient binders and their involvement in nutritional immunity will be briefly summarized. Their ability to bind nutrients and their close association with immune cells can trigger exaggerated immune responses and allergies in individuals with deficiencies. However, in nutrient-rich conditions, these allergens can also provide nutrients to immune cells and promote health.

Level of evidence in high impact surgical literature: the way forward

Evidence-based medicine stipulates that clinical decision-making should revolve around scientific evidence. The goal of the present study is to evaluate the methodological quality of surgical research recently published in JAMA Surgery, International Journal of Surgery, and British Journal of Surgery, the three surgical journals with the highest impact factor. An electronic search of the PUBMED database was performed to retrieve all articles published in the JAMA Surgery, International Journal of Surgery, and British Journal of Surgery in the year 2022. Three authors independently reviewed all retrieved articles and methodological designs of the publications were analyzed and rated using a modification of the Oxford Centre for Evidence-Based Medicine Levels of Evidence (Oxford Levels of Evidence scale). The initial search identified 1236 articles of which 809 were excluded after title and abstract screening. The remaining 427 underwent full text/methods read, of which 164 did not meet the inclusion/exclusion criteria. A total of 273 studies were included in the analysis. The average level of evidence was 2.5 ± 0.8 across all studies assessed. The majority of study designs were comprised of retrospective cohorts (n = 119), prospective cohorts (n = 47), systematic reviews of non RCTs (n = 39), and RCTs (n = 37). There was no significant difference in the average level of evidence between the top three journals (p = 0.50). Most clinical studies in the highest impact factor surgical journals are of level III evidence, consistent with earlier literature. However, our analysis demonstrates a relatively higher percentage of LOE I and II compared to what was previously published in the literature.

Anesthesiologists ultrasound-guided regional anesthesia core curriculum: a Delphi consensus from Italian regional anesthesia experts

INTRODUCTION

The need for a standardized core curriculum in regional anesthesia has become essential, particularly with the integration of ultrasound revolutionizing and exponentially increasing clinical practice and possibilities. In fact, numerous novel techniques, often overlapping, can confuse practitioners. This study aims to establish a core curriculum for upper limb, lower limb, paraspinal and fascial plane blocks for residency training, addressing potential educational gaps caused by the multitude of techniques, through a Delphi consensus process involving recognized Italian regional anesthesia experts.

METHODS

A steering committee was formed in order to select a panel of experts in regional anesthesia. A three-round Delphi consensus was planned: two rounds of electronic voting and a final round of mixed electronic voting and round table discussion. The consensus was defined as ≥ 75% agreement for inclusion and lower than ≤ 25% agreement for exclusion from the core curriculum list. Techniques reaching the 50% threshold were included with low consensus.

RESULTS

Twenty-nine techniques were selected to be included in the ultrasound-guided regional anesthesia core curriculum. Twenty-two were included with strong consensus: Upper limb: interscalene brachial plexus block, supraclavicular brachial plexus block, infraclavicular brachial plexus block, axillary brachial plexus block, intermediate cervical plexus block Lower limb: femoral nerve block, pericapsular nerve group block, adductor canal block, sciatic nerve block (transgluteal approach, infragluteal approach, and at the popliteal fossa), ankle block Paraspinal/fascial plane blocks: erector spinae plane block, deep serratus anterior plane block, superficial pectointercostal plane block, interpectoral plane block, pectoserratus plane block, rectus sheath block, ilioinguinal iliohypogastric nerves block, transversus abdominis plane block (with subcostal and midaxillary approaches) The remaining seven techniques were included with low consensus: superficial cervical plexus block, lumbar plexus block, fascia iliaca block (suprainguinal approach), anterior quadratus lumborum block, lateral quadratus lumborum block, paravertebral block, and serratus anterior plane block.

CONCLUSIONS

This curriculum aims to standardize training and ensure that residents acquire the essential skills required for effective and safe practice regardless of the residents' subsequent specialization. By incorporating these techniques, educational programs can provide a structured and consistent approach to regional anesthesia, enhancing the quality of patient care and improving outcomes.

Telomeres and SIRT1 as Biomarkers of Gamete Oxidative Stress, Fertility, and Potential IVF Outcome

The number of infertile couples undergoing in vitro fertilisation (IVF) has increased significantly. The efficacy of this procedure is contingent upon a multitude of factors, including gamete quality. One factor influencing gamete quality is oxidative stress, which leads to telomere damage and accelerates cellular ageing. Identifying new biomarkers that can predict the success of assisted reproduction techniques is a current relevant area of research. In this review, we discuss the potential role of SIRT1, a protein known to protect against oxidative stress and telomeres, which are responsible for genome stability, as biomarkers of gamete quality and assisted reproduction technique outcomes.

Erythrocyte Oxidative Status in People with Obesity: Relation to Tissue Losses, Glucose Levels, and Weight Reduction

BACKGROUND

This study aimed to investigate the impact of reductions in various body mass components on the erythrocyte oxidative status and glycemic state of people with obesity (PWO).

METHODS

A total of 53 PWO followed a six-month individualized low-calorie diet with exercise, during which anthropometric, biochemical, and oxidative parameters were measured. The participants were divided into groups based on weight (W), visceral fat area (VFA), total body water (TBW), and skeletal muscle mass (SMM) losses, as well as normoglycemia (NG) and hyperglycemia (HG).

RESULTS

Weight reduction normalized glycemia and influenced erythrocyte enzyme activity. Regardless of the tissue type lost (VFA, TBW, or SMM), glutathione peroxidase activity decreased in all groups, accompanied by an increase in glutathione reductase activity. Lipofuscin (LPS) and malondialdehyde (MDA) concentrations decreased regardless of the type of tissue lost. The α-/γ-tocopherol ratio increased in those losing >10% body weight, >15% VFA, and >5% TBW. In the NG group, compared to the HG group, there was a decrease in glutathione peroxidase and an increase in glutathione reductase, with these changes being stronger in the HG group. The LPS and MDA concentrations decreased in both groups. Significant correlations were observed between glucose reduction and changes in catalase, retinol, and α-tocopherol, as well as between VFA reduction and changes in vitamin E, L-LPS, and the activities of L-GR and L-GST.

CONCLUSIONS

This analysis highlights the complex interactions between glucose metabolism, oxidative state, and erythrocyte membrane integrity, crucial for understanding diabetes and its management. This study shows the significant metabolic adaptability of erythrocytes in response to systemic changes induced by obesity and hyperglycemia, suggesting potential therapeutic targets to improve metabolic health in obese individuals.

Telemedicine integration into the eye health ecosystem in scaling of effective refractive error coverage in Kenya

This study explored the potential of telemedicine integration into the eye health ecosystem with an aim of scaling effective refractive error coverage in Kenya. This exploratory study was conducted telephonically and through online interviews with key opinion leaders, ophthalmologists, optometrists, ophthalmic clinical officers, optical technicians and beneficiaries of the optical technician's services in rural areas. A telemedicine workflow was developed and validated based on the comments from the key opinion leaders using the Delphi technique. Quantitative and qualitative data were analysed using SPSS and NVivo Software respectively. All of the key opinion leaders agreed that telemedicine is relevant in the eye health ecosystem and recognition of primary vision technicians is critical for effective telemedicine integration. The reasons for the need of telemedicine integration were categorized into; good relationship, organized refractive error service delivery, convenience and availability and cost reduction. The possible factors influencing integration of telemedicine identified were categorized into cost, unwillingness, dominance, perception, lack of technical team, policies and network coverage. The limited human resources in the eye health ecosystem in developing countries cannot effectively deliver refractive error services to the growing population. Hence, integration of telemedicine and establishment of policies recognizing telemedicine are desirable to strengthen task shifting and scale effective refractive error coverage.

Surgical Implications for Nonalcoholic Steatohepatitis-Related Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is an aggressive form of liver cancer that arises in a background of chronic hepatic injury. Metabolic syndrome-associated fatty liver disease (MAFLD) and its severe form, nonalcoholic steatohepatitis (NASH), are increasingly common mechanisms for new HCC cases. NASH-HCC patients are frequently obese and medically complex, posing challenges for clinical management. In this review, we discuss NASH-specific challenges and the associated implications, including benefits of minimally invasive operative approaches in obese patients; the value of y90 as a locoregional therapy; and the roles of weight loss and immunotherapy in disease management. The relevant literature was identified through queries of PubMed, Google Scholar, and clinicaltrials.gov. Provider understanding of clinical nuances specific to NASH-HCC can improve treatment strategy and patient outcomes.

Impact of prior oral anticoagulation therapies on post-discharge outcomes after COVID-19: Results from a global federated health network analysis

BACKGROUND

The impact of chronic oral anticoagulant (OACs) use on long-term post-discharge outcomes after coronavirus disease 2019 (COVID-19) hospitalisation remains unclear. Herein, we compared clinical outcomes up to 2-years after COVID-19 hospitalisation between patients on vitamin K antagonists (VKAs), direct-acting OACs (DOACs) and no OAC therapy.

METHODS

Data from TriNetX, a global federated health research network, were used. Adult patients on VKAs, DOACs or no OAC therapy at diagnosis of COVID-19 between 20 January 2020 and 31 December 2021, who were hospitalised for COVID-19, were included. The primary outcomes were all-cause mortality, ischaemic stroke/transient ischaemic attack (TIA)/systemic embolism (SE) and the composite of intracranial haemorrhage (ICH)/gastrointestinal bleeding, at 2 years after COVID-19 hospitalisation.

RESULTS

We included 110,834 patients with COVID-19. Following propensity score matching (PSM), we identified a decreased mortality risk in DOAC-treated patients compared to the no OAC cohort (RR .808, 95% CI .751-.870). A higher risk of ischaemic stroke/TIA/SE was observed in VKA users compared to DOAC users (RR 1.100, 95% CI 1.020-1.220) and in VKA users compared to patients not taking OAC (RR 1.400, 95% CI 1.140-1.720). VKA use was associated with a greater risk of ICH/gastrointestinal bleeding than DOAC users (RR 1.198, 95% CI 1.066-1.347), while DOAC users had a lower risk compared to no OAC-treated patients (RR .840, 95% CI .754-.936).

CONCLUSION

COVID-19 patients taking prior DOACs were associated with lower long-term mortality risk and ICH/gastrointestinal bleeding than patients not taking OAC. Compared to patients on DOACs, VKA users were associated with higher risks of mortality, ischaemic stroke/TIA/SE and ICH/gastrointestinal bleeding.

Association between the length of stay in rehabilitation and mortality among the adults with Parkinson's disease: 2009-2019 Korean National Health Insurance Service Databases

Background

Rehabilitation is recognized as an effective means of alleviating the symptoms of Parkinson's disease (PD) and improving the physical and cognitive functions of patients with PD. However, research often focuses on short-term outcomes such as functioning and quality of life. This study investigated the association between the length of stay in rehabilitation and mortality among patients with PD.

Methods

Using the Korean National Health Insurance Service database, we identified 636 participants diagnosed with PD who received rehabilitation. The main outcome was all-cause mortality. We used a Cox proportional hazards regression model to examine the relationship between length of stay in rehabilitation and mortality among patients with PD.

Results

The final sample comprised 374 females (58.81%) and 262 males (41.19%). A survival analysis revealed a significant association between the length of stay in rehabilitation and mortality, with a decrease in mortality of 16.1% in patients with PD who received one year of rehabilitation (hazard ratio = 0.839, 95% confidence interval = 0.788-0.895).

Conclusion

Our findings underscore the potential benefits of timely implementation of rehabilitative interventions in patients with PD and the need for comprehensive and long-term rehabilitation strategies. It also highlights the necessity of such services for patients with PD and the importance of developing patient-centered rehabilitation guidelines.

Determining the Key Education Priorities Related to Heart Failure Care in Nursing Homes: A Modified Delphi Approach

There is currently a limited understanding of what nurses in nursing homes view as the key education priorities to support their ability to provide the appropriate care for residents with heart failure (HF). A modified Delphi technique was utilized to gain a consensus on the key education priorities for nurses working in nursing homes in Northern Ireland. An initial list of items (n = 58), across 19 domains, was generated using the findings of a scoping review and stakeholder interviews, and a review of available clinical guidelines. Two rounds of surveys were undertaken. Items were presented using a 5-point Likert scale, with an additional exercise in the second round to rank the domains in order of importance. Fifty-four participants completed the first-round survey and 34 (63%) returned to complete the second. The findings highlight the importance of providing nurses in nursing home settings with general HF education and the delivery of person-centered care. Participants perceived education around technology for the management of HF and quality improvement or research methodologies associated with HF in nursing homes as lower priorities. This study illuminates key priorities from nursing home nurses regarding HF education that are applicable to this care setting.

Patellar articular overlap is better associated with patellar alignment during weight-bearing than traditional measures of patellar height

BACKGROUND

A consequence of a high riding patella is reduced osseous stability and malalignment of the patella (i.e., lateral patellar tilt and displacement). Although quantification of patellar height is a routine part of the radiographic examination of the patellofemoral joint, it is not clear which measure of patellar height is best associated with patella alignment.

HYPOTHESIS/PURPOSE

To determine if patellar articular overlap (PAO) is better associated with lateral patellar tilt and lateral patellar displacement compared to traditional measures of patellar height.

STUDY DESIGN

Cross-sectional.

METHODS

Magnetic resonance images were obtained from 50 female participants (21 with patellofemoral pain and 29 healthy controls) under loaded conditions (25-35% bodyweight) at 15-20 degrees of knee flexion. Measurements of lateral patellar tilt and displacement as well as the PAO, Insall-Salvati ratio (ISV), Caton Deschamps-index (CD-index), or the Blacburn Peel-index (BP-index) were obtained from sagittal and axial plane images.

RESULTS

The PAO was found to significantly correlated with lateral patellar tilt (r = -0.77, p < 0.001). In contrast, the ISV, CD-index, or the BP-index were not found to be associated with lateral patellar tilt (r = 0.13, p = 0.34; r = -0.14, p = 0.33; r = -0.08, p = 0.56, respectively). Both the PAO and ISV were found to be significantly correlated with lateral patellar displacement (r = -0.52, p < 0.001; r = 0.43, p = 0.002, respectively). Conversely, the CD-index and BP-index were not found to be associated with lateral patellar displacement (r = 0.03 p = 0.83; r = 0.05 p = 0.74, respectively).

CONCLUSION

Of the measures of patellar height evaluated, the PAO was found to provide the greatest association with lateral patellar tilt and displacement.

ISCCM Position Statement for Improving Gender Balance in Critical Care Medicine

Gender disparity in Critical Care Medicine (CCM) persists globally, with women being underrepresented. Female Intensivists remain a minority, facing challenges in academic and leadership positions at the workplace and within academic societies. The Indian Society of Critical Care Medicine (ISCCM) recognized the need for addressing issues related to gender parity and constituted its first Diversity Equity and Inclusion (DEI) Committee in 2023. Through a Delphi process involving 38 Panelists including 53% women, consensus and stability were achieved for 18 statements (95%). From these 18 consensus statements, 15 position statements were drafted to address gender balance issues in CCM. These statements advocate for equal opportunities in recruitment, workplace inclusivity, prevention of harassment, and improved female representation in leadership roles, nominated positions, and conferences. While the consensus reflects a significant step toward gender equity, further efforts are required to implement, advocate, and evaluate the impact of these measures. The ISCCM position statements offer valuable guidance for promoting gender balance within society and the CCM community.

Pre-transplant Loco-Regional Therapy for Hepatocellular Carcinoma and Post-transplant Outcomes: A National Study

The ultimate preferred treatment for hepatocellular carcinoma (HCC) complicated with cirrhosis and portal hypertension is an orthotopic liver transplant (OLT). Loco regional therapy (LRT) has emerged to prevent tumor growth and progression of disease beyond the Milan criteria to achieve transplant. There is a paucity of data regarding safety, posttransplant survival benefits, and tumor recurrence rate achieved by these LRT modalities. We aim to assess and compare the five-year survival rate and tumor recurrence rate with or without LRT in patients after OLT with diagnosed HCC utilizing the nation's largest dataset. This is a retrospective observational study approved by Saint Louis University institutional review board. We utilized the largest dataset from the years 2003-2013 where pertaining data were gathered from Organ Procurement Transplant Network (OPTN) standard analysis and research files (STAR) through novel linkages with Medicare bills. Descriptive and comparative statistics were performed. 2412 (51.6%) patients received any form of locoregional therapy (single or combination) out of 4669 total study sample size. The overall five-year survival in the study sample was 76.1%. There was statistically no significant improvement seen in five-year posttransplant survival in the group that received one mode of LRT (adjusted hazard ratio (aHR) 0.97, P<0.64) or a combination of LRT (aHR 0.94, P<0.58) in comparison to those that received none after adjusting donor and recipient clinical characteristics. However, five-year survival trended higher among those treated with combination therapy over those treated with single LRT or none. Overall HCC recurrence was 4.8%, while no significant difference was noted when comparing above-mentioned groups. Five-year posttransplant survival and HCC recurrence rate were also found to have no difference when compared between above-mentioned groups after adjusting explant pathology. This is the largest retrospective study comparing liver transplant patients with HCC who received LRT to none. Although it did not show any statistically significant benefit of single or combination of LRT on survival or tumor recurrence after liver transplant for HCC patients, the outcomes encourage the safe and feasible use of LRT as a bridging therapy. Our study also suggests an observed pattern of improved posttransplant survival and tumor recurrence rate with combination loco-regional therapy. Larger multicenter prospective studies will be required to achieve the effect size to determine the best therapies for maximizing patient survival cost-effectively.

Feeling of pulsations in artificial arteries with a real time haptic feedback laparoscopic grasper: a validation study

INTRODUCTION

Despite the advancements in technology and organized training for surgeons in laparoscopic surgery, the persistent challenge of not being able to feel the resistance and characteristics of the tissue, including pulsations, remains unmet. A recently developed grasper (Optigrip®) with real time haptic feedback, based on photonic technology, aims to address this issue by restoring the tactile sensation for surgeons. The key question is whether pulsations can be detected and at what minimal size level they become clinical significant.

METHODS

To simulate arterial conditions during laparoscopic procedures, four different silicone tubes were created, representing the most prevalent arteries. These tubes were connected to a validated pressure system, generating a natural pulse ranging between 80 and 120 mm Hg. One control tube without pressure was added. The surgeons had to grasp these tubes blindly with the conventional grasper or the haptic feedback grasper in a randomized order. They then indicated whether they felt the pressure or not and the percentage of correct answers was calculated.

RESULTS

The haptic grasper successfully detected 96% of all pulsations, while the conventional grasper could only detect 6%. When considering the size of the arteries, the Optigrip® identified pulsations in 100% the 4 and 5 mm arteries and 92% of the smallest arteries. The conventional grasper was only able to feel the smallest arteries in 8%. These differences were highly significant (p < 0.0001).

CONCLUSION

This study demonstrated that the newly developed haptic feedback grasper enables detection of arterial pulsations during laparoscopy, filling an important absence in tactile perception within laparoscopic surgery.

Monitoring and integrated care coordination of patients with alpha-mannosidosis: A global Delphi consensus study

INTRODUCTION

Current literature lacks consensus on initial assessments and routine follow-up care of patients with alpha-mannosidosis (AM). A Delphi panel was conducted to generate and validate recommendations on best practices for initial assessment, routine follow-up care, and integrated care coordination of patients with AM.

METHODS

A modified Delphi method involving 3 rounds of online surveys was used. An independent administrator and 2 nonvoting physician co-chairs managed survey development, anonymous data collection, and analysis. A multidisciplinary panel comprising 20 physicians from 12 countries responded to 57 open-ended questions in the first survey. Round 2 consisted of 11 ranking questions and 44 voting statements. In round 3, panelists voted to validate 60 consensus statements. The panel response rate was ≥95% in all 3 rounds. Panelists used 5-point Likert scales to indicate importance (score of ≥3) or agreement (score of ≥4). Consensus was defined a priori as ≥75% agreement with ≥75% of panelists voting.

RESULTS

Consensus was reached on 60 statements, encompassing 3 key areas: initial assessments, routine follow-up care, and treatment-related follow-up. The panel agreed on the type and frequency of assessments related to genetic testing, baseline evaluations, quality of life, biochemical measures, affected body systems, treatment received, and integrated care coordination in patients with AM. Forty-nine statements reached 90% to 100% consensus, 8 statements reached 80% to 85% consensus, and 1 statement reached 75% consensus. Two statements each reached consensus on 15 baseline assessments to be conducted at the initial follow-up visit after diagnosis in pediatric and adult patients.

CONCLUSION

This is the first Delphi study providing internationally applicable, best-practice recommendations for monitoring patients with AM that may improve their care and well-being.

Primary mantle-cell lymphoma of small intestine presenting with intussusceptions: A case report and review of the literature

INTRODUCTION AND IMPORTANCE

Mantle cell lymphoma is a rare type of non-Hodgkin's lymphoma which accounts for 5 % of all cases. Patients present with an advanced form of the disease. We present here a case of ileocolic intussusception secondary to mantle cell lymphoma which was revealed by abdominal pain and vomiting that was treated by surgical resection followed by chemotherapy.

CASE PRESENTATION

This report illustrates the case of a 34-year-old male who presented with abdominal pain and vomiting. Imageology demonstrated an ileocolic intussusception which was treated with hemicolectomy followed by chemotherapy. Histopathology confirmed the diagnosis of Mantle cell lymphoma.

CLINICAL DISCUSSION

Mantel cell lymphoma is a rare type of B-cell cancer. Patients are generally diagnosed with an advanced stage of the disease. Ileocolic intussusception is an uncommon presentation. Surgery is the pillar of the treatment. Resection depends on the extent and location of the lesion. Postoperative chemotherapy is crucial and it increases survival rate.

CONCLUSION

Mantle cell lymphoma is a rare subgroup of B-cell lymphomas. Ileocolic intussusception is a complicated form of the disease. Surgery combined with chemotherapy is the mainstay of the treatment. Diagnosis is confirmed by histological analysis of the surgical specimen.

Conceptual Framework of Upper Cross Syndrome: A Delphi Study

BACKGROUND

Upper cross syndrome (UCS) is one of the most common postural dysfunctions due to prolonged flexed attitude. Good posture plays an important role in maintaining musculoskeletal balance and protecting it from further injury. Conducting research on the conceptual framework will help clinicians to identify and plan treatment strategies for the correction of this syndrome and prevent secondary complications. Thus, the aim of this study was to develop a conceptual framework for UCS.

METHODS AND MATERIAL

The Delphi method was used to conduct the study and develop a conceptual framework. A total of 30 multidisciplinary experts participated in the study, and a list of 41 items was finalized after an extensive literature review. A cover letter along with all the items was mailed to the experts to obtain their input. Three rounds of Delphi were conducted until a consensus was reached. The following parameters were used to determine consensus: moderate Kendall's coefficient of concordance (Kendall's W), agreement greater than 51.0%, interquartile range (IQR) below 1.5, and standard deviation (SD) below 1.

RESULTS

By the end of the third round, 37 items were finalized. The conceptual framework consisted of four items in postural alignment, eight items in muscular imbalance, 20 items in functional limitation, and five items in the psychosocial domain.

CONCLUSION

We successfully developed a conceptual framework for UCS. Four domains, including postural alignment, muscular imbalance, functional limitation, and psychosocial, were identified. This will lead to a deeper comprehension of UCS, which will facilitate its early detection and treatment. The multidimensional approach of the study will provide a better scope for the clinicians to educate the patient about good posture, which not only will impact physical performance but also improve quality of life. The development of this framework will help to prevent, monitor the progress, and correct UCS.

PURPOSE

Approximately 20 million individuals worldwide undergo inguinal hernia surgery annually. The Lichtenstein technique is the most commonly used surgical procedure in this setting. The objective of this study was to revisit this technique and present ten recommendations based on the best practices.

METHODS

PubMed and Scientific Electronic Library Online were used to systematically search for articles about the Lichtenstein technique and its modifications. Literature regarding this technique and surgical strategies to prevent chronic pain were the basis for formulating ten recommendations for best practices during Lichtenstein surgery.

RESULTS

Ten recommendations were proposed based on best practices in the Lichtenstein technique: neuroanatomical assessment, chronic pain prevention, pragmatic neurectomy, spermatic cord structure management, femoral canal assessment, hernia sac management, mesh characteristics, fixation, recurrence prevention, and surgical convalescence.

CONCLUSION

The ten recommendations are practical ways to achieve a safe and successful procedure. We fell that following these recommendations can improve surgical outcomes using the Lichtenstein technique.

General nurse competencies in disaster: A delphi study

AIM

The aim of this study is to understand the significance of a disaster-related competence framework for Portuguese general nurses and identify from ICN - Core Competencies in Disaster Nursing version 2.0 core competencies description, those that are considered crucial for a competent preparedness and response in disaster scenarios.

BACKGROUND

Research suggests that the occurrence of disasters will be more recurrent, requiring that nurses, pillars of any health system, have knowledge, skills and preparedness to face these events.

DESIGN

An exploratory, cross-sectional qualitative study was carried out. Delphi method was used for data collection.

METHODS

The study group consisted of technical-scientific council's presidents or coordinators/directors of nursing courses, nurses integrated in the Portuguese Council of Nurses and National Nursing Specialty Colleges and nurses with experience in the field of disasters.

RESULTS

Findings revealed that there is consensus on sixteen competencies, considered relevant for developing general nurse knowledge and competence, both at a national or international level, in the field of disasters.

CONCLUSIONS

The development of these competencies which establishes practice standards, building nurses skills and knowledge and ultimately, influencing nursing level-entry curricula's, conferring professional autonomy and self-regulation, in the field of disaster are fundamental. Furthermore, this study may serve as a reference for future alignment of competency frameworks between European Union countries or others.

Ileocolic intussusception secondary to Peutz-Jeghers polyp: the need for oncological resection surgery

In this case report, we detail the management of a woman in her late 30s with ileocolic intussusception, emphasizing the high malignancy risk inherent in adult intussusception cases. Given the patient's acute symptoms and significant family history of ovarian and breast cancers, radical oncological resection was pursued. The surgical intervention comprised a right hemicolectomy and right ovarian cystectomy, with histopathological findings revealing a Peutz-Jeghers polyp and benign thyroid tissue, but no malignancy. This case underscores the imperative for a surgical approach that anticipates the potential for malignancy in adult intussusception, advocating for radical resection as a fundamental strategy, even in the absence of confirmed malignant histopathology, to ensure comprehensive management and alignment with oncological best practices.

CD4+ chronic lymphocytic leukemia in an 86-year-old male veteran: A case report

CD4+ chronic lymphocytic leukemia (CLL) represents an extremely rare example of phenotypic aberrancy within CLL. We present a case of an 86-year-old male veteran with a history of multiple comorbidities who was incidentally diagnosed with CD4+ CLL during a routine peripheral blood workup. This case highlights the diagnostic challenges and characteristic features of CD4+ CLL, including flow cytometric analysis, molecular, and fluorescence in situ hybridization findings. The patient was classified as asymptomatic CLL Rai stage 0, warranting regular monitoring without a need for treatment intervention.

Policies and Practices Facilitating Access to and Uptake of HIV Testing Services among Adolescents in Sub-Sahara Africa: A Narrative Review

PURPOSE OF REVIEW

Expanding access to HIV testing services and linking newly diagnosed positive adolescents to antiretroviral therapy is critical to epidemic control. However, testing coverage and treatment initiation rates continue to lag behind adult counterparts. This article synthesizes evidence on facilitative policies and service delivery practices focused on adolescents to inform programming.

RECENT FINDINGS

Our narrative review found that national policies are growing more adolescent-inclusive but barriers around the age of consent, waiver frameworks and dissemination constrain translate into practice. Facility-based provider-initiated testing through integrated sexual health services and dedicated youth centres demonstrates uptake effectiveness if confidentiality and youth-friendly adaptations are assured. Supportive policies, youth-responsive adaptations across testing models and strengthening age-disaggregated monitoring are vital to improving adolescents' engagement across the HIV testing and treatment cascade. Further implementation research is imperative to expand the reach of adolescent HIV testing in sub-Saharan Africa.

Potentiation of anti-angiogenic eNOS-siRNA transfection by ultrasound-mediated microbubble destruction in ex vivo rat aortic rings

Nitric oxide (NO) regulates vascular homeostasis and plays a key role in revascularization and angiogenesis. The endothelial nitric oxide synthase (eNOS) enzyme catalyzes NO production in endothelial cells. Overexpression of the eNOS gene has been implicated in pathologies with dysfunctional angiogenic processes, such as cancer. Therefore, modulating eNOS gene expression using small interfering RNAs (siRNAs) represents a viable strategy for antitumor therapy. siRNAs are highly specific to the target gene, thus reducing off-target effects. Given the widespread distribution of endothelium and the crucial physiological role of eNOS, localized delivery of nucleic acid to the affected area is essential. Therefore, the development of an efficient eNOS-siRNA delivery carrier capable of controlled release is imperative for targeting specific vascular regions, particularly those associated with tumor vascular growth. Thus, this study aims to utilize ultrasound-mediated microbubble destruction (UMMD) technology with cationic microbubbles loaded with eNOS-siRNA to enhance transfection efficiency and improve siRNA delivery, thereby preventing sprouting angiogenesis. The efficiency of eNOS-siRNA transfection facilitated by UMMD was assessed using bEnd.3 cells. Synthesis of nitric oxide and eNOS protein expression were also evaluated. The silencing of eNOS gene in a model of angiogenesis was assayed using the rat aortic ring assay. The results showed that from 6 to 24 h, the transfection of fluorescent siRNA with UMMD was twice as high as that of lipofection. Moreover, transfection of eNOS-siRNA with UMMD enhanced the knockdown level (65.40 ± 4.50%) compared to lipofectamine (40 ± 1.70%). Silencing of eNOS gene with UMMD required less amount of eNOS-siRNA (42 ng) to decrease the level of eNOS protein expression (52.30 ± 0.08%) to the same extent as 79 ng of eNOS-siRNA using lipofectamine (56.30 ± 0.10%). NO production assisted by UMMD was reduced by 81% compared to 67% reduction transfecting with lipofectamine. This diminished NO production led to higher attenuation of aortic ring outgrowth. Three-fold reduction compared to lipofectamine transfection. In conclusion, we propose the combination of eNOS-siRNA and UMMD as an efficient, safe, non-viral nucleic acid transfection strategy for inhibition of tumor progression.

Clinical Staging of Prostaglandin-Associated Periorbitopathy Syndrome in Glaucoma: A Review from Asia

PURPOSE

Topical prostaglandin analogues are commonly used to treat patients with glaucoma, but may cause periocular and periorbital complications known as prostaglandin-associated periorbitopathy syndrome (PAPS).

METHODS

A literature review was conducted on PAPS. Given the lack of consensus on grading PAPS, glaucoma specialists from Asia convened to evaluate current PAPS grading systems and propose additional considerations in grading PAPS.

RESULTS

Existing grading systems are limited by the lack of specificity in defining grades and consideration for patients' subjective perception of symptoms. Patient-reported symptoms (e.g., via a self-assessment tool) and additional clinical assessments (e.g., exophthalmometry, lid laxity, differences between tonometry results, baseline measurements, and external ocular photographs) would be beneficial for grading PAPS systematically.

CONCLUSIONS

Effective management of PAPS could be facilitated by a common clinical grading system to consistently and accurately diagnose and characterise symptoms. Further research is required to validate specific recommendations and approaches to stage and monitor PAPS.

Sustainability challenges concerning the effects of high-priced drugs on the day-to-day operations of community pharmacies in Finland

BACKGROUND

High-priced drugs pose a challenge for health budgets, policies, and patient safety. One of the key roles of community pharmacies is to ensure availability to prescription drugs regardless of their price. This has been identified as challenging in certain situations concerning high-priced drugs.

OBJECTIVES

The aim is to investigate the views of proprietary pharmacists regarding the effects of high-priced drugs on the day-to-day operations of pharmacies.

METHODS

The data collection of the study was performed as a national cross-sectional online survey. The inclusion criteria were being a proprietary pharmacist and a member of the Association of Finnish Pharmacies. The survey contained questions yielding both quantitative and qualitative answers. The study focused on the qualitative data which was analysed by deductive thematic analysis.

RESULTS

In total 604 proprietary pharmacists were sent the survey, and 174 eligible answers were included in the study, giving a response rate of 29%. The result describes the relationships between the economic, social, and environmental dimensions of sustainable development based on a framework by Wanamaker, with respect to high-priced drugs and community pharmacy operations as viewed by proprietary pharmacists. The main findings of the study show that proprietary pharmacists find the implementation of real-time reimbursement payments, a further reform of the pharmacy tax, and the abolishment of return bans to the wholesaler as risk mitigations and means to attain sustainability with respect to high-priced drugs and pharmacy practice. They experience that these changes would diminish high-priced drugs unnecessarily ending up as medical waste and improve the working conditions of the pharmacy staff by alleviating stress.

CONCLUSIONS

According to the respondents, high-priced drugs pose challenges for community pharmacies and the legislation and reimbursement system need to adapt to these challenges. If not, community pharmacies in Finland continue to face severe financial declines based on the study results.

The impact of macro- and micro-steatosis on the outcomes of patients who undergo liver transplant: Analysis of the UNOS-STAR database

BACKGROUND AND AIMS

The presence of steatosis in a donor liver and its relation to post-transplantation outcomes are not well defined. This study evaluates the effect of the presence and severity of micro- and macro-steatosis of a donor graft on post-transplantation outcomes.

METHODS

The UNOS-STAR registry (2005-2019) was used to select patients who received a liver transplant graft with hepatic steatosis. The study cohort was stratified by the presence of macro- or micro-vesicular steatosis, and further stratified by histologic grade of steatosis. The primary endpoints of all-cause mortality and graft failure were compared using sequential Cox regression analysis. Analysis of specific causes of mortality was further performed.

RESULTS

There were 9184 with no macro-steatosis (control), 150 with grade 3 macro-steatosis, 822 with grade 2 macro-steatosis and 12 585 with grade 1 macro-steatosis. There were 10 320 without micro-steatosis (control), 478 with grade 3 micro-steatosis, 1539 with grade 2 micro-steatosis and 10 404 with grade 1 micro-steatosis. There was no significant difference in all-cause mortality or graft failure among recipients who received a donor organ with any evidence of macro- or micro-steatosis, compared to those receiving non-steatotic grafts. There was increased mortality due to cardiac arrest among recipients of a grade 2 macro-steatosis donor organ.

CONCLUSION

This study shows no significant difference in all-cause mortality or graft failure among recipients who received a donor liver with any degree of micro- or macro-steatosis. Further analysis identified increased mortality due to specific aetiologies among recipients receiving donor organs with varying grades of macro- and micro-steatosis.

'There's Nothing Wrong With You; You Just Need to Lose Weight'-A Qualitative Exploration of Pelvic Floor Dysfunction Among Women With Multiple Sclerosis and Their Interaction in Seeking Pelvic Healthcare

INTRODUCTION

Within 10 years of multiple sclerosis (MS) progression, nearly all women will have experienced symptoms associated with bladder, bowel and/or sexual health. Yet despite the impact these symptoms have on physical, psychological and social well-being, it remains an underserved area within the UK healthcare system.

STUDY AIM

This research employs a participatory research approach framed within the principles of intersectional feminism to collaboratively investigate the lived experiences of pelvic floor dysfunction (PFD) and healthcare interactions among UK-based women with MS.

SETTING AND PARTICIPANTS

Women residing in the United Kingdom with MS were invited to participate in online interviews facilitated by the primary author.

ANALYSIS

A thematic framework analysis offering a structured yet adaptable approach to data collection and interpretation.

RESULTS

One focus group involving four women with MS and seven individual, one-to-one interviews with women with MS provided insights into the challenges associated with navigating both MS and PFD. Four main themes included: Navigating MS and PFD; Cycles of Control; Mind, Mobility and Bladder Embodiment; Silenced Voices: The Impact of Taboos/Stigma/Dismissal on Preventing Access and Resistance through Collective Community. Six subthemes were also identified. Taken together, these themes cumulatively reflect PFD as an unmet healthcare need.

CONCLUSION

Our findings underscore negative healthcare experiences, inadequate information provision and unmet needs related to PFD, emphasising the compounding effects of gender and disability biases.

IMPACT

We hope that these insights can lay the groundwork for developing tailored therapeutic interventions and improved PFD healthcare for women with MS. Potential solutions include using existing MS support communities.

PUBLIC CONTRIBUTIONS

Women with MS were actively involved in co-producing interview scripts for one-to-one interviews. The primary author shared study findings at an MS group event, engaging in discussions with over 30 individuals, including people with MS and their loved ones. MS advocates played a pivotal role in contextualising the study within the broader lived experience of MS.

Leveraging and learning from the long COVID experience: Translating telerehabilitation into practice

BACKGROUND

Telerehabilitation, or the delivery of rehabilitation services through telehealth platforms, has existed since the late 1990 s. Telerehabilitation was characterized by unprecedented, exponential growth at the beginning of the novel coronavirus-2019 (COVID-19) pandemic. Medical systems sought to reduce the likelihood of disease transmission by using telerehabilitation to limit physical proximity during routine care. This dramatic change in how medical care was delivered forced many professions to adapt processes and practices. Following the change, debates sparked regarding the best path to move forward for the betterment of patients, clinicians, systems, and society. Long COVID has emerged as a complex chronic health condition arising from COVID-19. The unique needs and dynamic disease process of Long COVID has incentivized medical systems to create equitable ways for patients to safely access interdisciplinary care.

OBJECTIVES

The purpose of this commentary is to describe what medical systems must consider when deploying high-quality telerehabilitation to deliver rehabilitation through asynchronous (e.g., text, portal) and synchronous modalities (e.g., phone or video). We highlight lessons learned to help guide decision-makers on key actions to support their patients and clinicians.

METHODS

Not applicable.

RESULTS

Not applicable.

CONCLUSIONS

Key action steps from our lessons learned may be used to address complex chronic health conditions such as Long COVID and prepare for future challenges that may disrupt medical systems.

An Unusual Presentation of Failure to Thrive in a Toddler: Bartter Syndrome

Bartter syndrome is a rare salt-wasting renal tubular disorder of autosomal-recessive inheritance. Antenatal Bartter syndrome (types I, II, and IV) manifests in infancy and has a more severe course compared to the classic Bartter syndrome (type III). This report details a unique instance of a male toddler, aged 18 months, who presented with failure to thrive, polydipsia, and polyuria. Blood gases revealed hypochloremic metabolic alkalosis with hyponatremia and hypokalemia. The diagnosis was confirmed by genetic testing, and the child was started on indomethacin and potassium supplementation. Despite being rare in children, this case report emphasizes the importance of looking beyond the usual in a child who presents with failure to thrive to prevent a delay in the diagnosis and treatment.

Cardiac arrest and cardiopulmonary resuscitation outcome reports: 2024 update of the Utstein Out-of-Hospital Cardiac Arrest Registry template

The Utstein Out-of-Hospital Cardiac Arrest Resuscitation Registry Template, introduced in 1991 and updated in 2004 and 2015, standardizes data collection to enable research, evaluation, and comparisons of systems of care. The impetus for the current update stemmed from significant advances in the field and insights from registry development and regional comparisons. This 2024 update involved representatives of the International Liaison Committee on Resuscitation and used a modified Delphi process. Every 2015 Utstein data element was reviewed for relevance, priority (core or supplemental), and improvement. New variables were proposed and refined. All changes were voted on for inclusion. The 2015 domains-system, dispatch, patient, process, and outcomes-were retained. Further clarity is provided for the definitions of out-of-hospital cardiac arrest attended resuscitation and attempted resuscitation. Changes reflect advancements in dispatch, early response systems, and resuscitation care, as well as the importance of prehospital outcomes. Time intervals such as emergency medical service response time now emphasize precise reporting of the times used. New flowcharts aid the reporting of system effectiveness for patients with an attempted resuscitation and system efficacy for the Utstein comparator group. Recognizing the varying capacities of emergency systems globally, the writing group provided a minimal dataset for settings with developing emergency medical systems. Supplementary variables are considered useful for research purposes. These revisions aim to elevate data collection and reporting transparency by registries and researchers and to advance international comparisons and collaborations. The overarching objective remains the improvement of outcomes for patients with out-of-hospital cardiac arrest.

Review of the Australian nurse teacher professional practice standards: An e-Delphi study

AIM

The aim of the study was to review the 2010 Australian nurse teacher professional practice standards ('the Standards') to see if they were still relevant to current nursing educator practice in any practice setting, such as academia or clinical settings.

BACKGROUND

It has been over 10 years since 'the Standards have been reviewed. Nurse education practice has met many challenges in the past decade, so it is timely to evaluate whether the Standards are still relevant to nursing educators today.

DESIGN

A modified Delphi technique was used for this study.

METHODS

Delphi surveys were used to obtain consensus on the relevance of the Standards' statements to any nursing educator. Links to two electronic surveys were sent to an expert panel of nursing educator leaders. Also, two online focus groups of nursing educators from any practice setting or level of experience were held. Results from the first survey and focus groups led to word changes and additional statements, which were included in the second Delphi survey.

RESULTS

Forty participants responded to the first survey and 38 to the second. Fifteen nursing educators attended the focus groups. There was ≥85 % agreement on all statements in the first survey. with similar high agreement responses in the second survey. Changes in the Standards included language used around culture, inclusion of 'sustainability of the program' and 'demonstrates knowledge and expertise in teaching and educational practice'.

CONCLUSIONS

The Australian nurse teacher professional practice standards remain highly relevant to nursing educators across all practice settings. In response to feedback from nursing educators some changes to language and additional standard statements were included in the revised standards.

Consensus Guidelines for Assessment and Comprehensive Outcomes Evaluation in Rural Pain Clinics

Recent advancements in nurse anesthesiology fellowship training programs have helped to establish advanced pain management services for rural communities. Consensus guidelines to direct the rural provider toward the most valid and reliable measures for pain assessment and functional outcomes evaluation are not presently available. The primary aim of this initiative was to establish consensus guidelines for a comprehensive outcome evaluation program with specific time intervals for assessments that can be utilized by all rural pain clinics. The American Association of Nurse Anesthesiology Nonsurgical Pain Management Advisory Panel members provided formative and expert feedback for this initiative. The Delphi model was utilized to achieve consensus through multiple rounds of surveys. Items achieving >70% agree/strongly agree were kept; items with >70% disagree/strongly disagree were rejected; items meeting neither advanced to the following round for evaluation until consensus was met. During round I, consensus was reached for: (1) the use of the Numerical Rating Scale for pain severity; and (2) timing of pain severity & functional pain outcomes on each office visit and before/after each intervention. Round II, consensus was achieved for: (1) the use of Wong-Baker FACES Pain Rating Scale as a suitable instrument when literacy or communication pose a barrier but not as a primary assessment; and (2) the use of the Brief Pain Index-Short Form for functional outcome measures. During round III, consensus was reached for: (1) the use of the Oswestry Disability Index as a functional outcome measure; and (2) pain reassessment being performed within 14 days of intervention. This initiative provides rural pain clinics with a comprehensive outcome evaluation program with specific time intervals for assessments.

Reovirus infection induces transcriptome-wide unique A-to-I editing changes in the murine fibroblasts

The conversion of Adenosine (A) to Inosine (I), by Adenosine Deaminases Acting on RNA or ADARs, is an essential post-transcriptional modification that contributes to proteome diversity and regulation in metazoans including humans. In addition to its transcriptome-regulating role, ADARs also play a major part in immune response to viral infection, where an interferon response activates interferon-stimulated genes, such as ADARp150, in turn dynamically regulating host-virus interactions. A previous report has shown that infection from reoviruses, despite strong activation of ADARp150, does not influence the editing of some of the major known editing targets, while likely editing others, suggesting a potentially nuanced editing pattern that may depend on different factors. However, the results were based on a handful of selected editing sites and did not cover the entire transcriptome. Thus, to determine whether and how reovirus infection specifically affects host ADAR editing patterns, we analyzed a publicly available deep-sequenced RNA-seq dataset, from murine fibroblasts infected with wild-type and mutant reovirus strains that allowed us to examine changes in editing patterns on a transcriptome-wide scale. To the best of our knowledge, this is the first transcriptome-wide report on host editing changes after reovirus infection. Our results demonstrate that reovirus infection induces unique nuanced editing changes in the host, including introducing sites uniquely edited in infected samples. Genes with edited sites are overrepresented in pathways related to immune regulation, cellular signaling, metabolism, and growth. Moreover, a shift in editing targets has also been observed, where the same genes are edited in infection and control conditions but at different sites, or where the editing rate is increased for some and decreased for other differential targets, supporting the hypothesis of dynamic and condition-specific editing by ADARs.
