This report provides a concise selective representative overview of the predictor factors for progression in Idiopathic Scoliosis (IS). The Cobb angle method, rib hump deformity, imaging and advanced techniques for assessing skeletal maturity serve as key elements in evaluating prognostic factors for IS progression based on the patient’s age at diagnosis—particularly in Infantile Idiopathic Scoliosis (IIS), Juvenile Idiopathic Scoliosis (JIS), and Adolescent Idiopathic Scoliosis (AIS). The commonly used approaches for determining skeletal maturity include the assessment of the iliac apophysis and scoliosis curve deterioration, the Sanders skeletal maturity staging system, the distal radius and ulna (DRU) classification for predicting growth spurts and curve progression in IS, as well as the ossification of vertebral epiphyseal rings, the humeral head, and the calcaneal apophysis. Prognostic factors influencing IS progression are further discussed in relation to the patient’s age at onset—whether in infancy, childhood, or adolescence—as well as in both untreated and braced AIS patients. Additionally, the apical convex rib–vertebra angle in AIS is explored as an indicator of progression. Predictors for curve progression at skeletal maturity are outlined, along with various models for forecasting IS deterioration. Lastly, the Rib and Segmental Rib Index, a rib cage deformity parameter, is introduced as a predictor of scoliosis progression. In conclusion, this concise and selective overview of predictor factors for progression in IS highlights the current understanding of IS progression factors. It also introduces the Rib and Segmental Rib Index—a rib cage deformity parameter—as a predictor of IS progression. Full article

Background/Objectives: Facial melasma is a common, chronic, and relapsing hyperpigmentation disorder, affecting up to 40% of adult women in Southeast Asia. Although most cases are mild, the condition may have a considerable psychological impact. Ocular photoaging diseases are also common and have been increasingly recognized in aging populations exposed to chronic sunlight. Ultraviolet (UV) radiation is implicated in both melasma and ocular photoaging; however, their relationship remains unclear. Methods: This cross-sectional study investigated the association between facial melasma and UV-induced ocular conditions among 315 participants aged 30–80 years at Walailak University Hospital, Thailand. Facial melasma was diagnosed clinically and dermoscopically, with severity assessed using the modified Melasma Area Severity Index. Ophthalmological examinations evaluated UV-related ocular conditions, including pinguecula, pterygium, climatic droplet keratopathy, cataracts, and age-related macular degeneration. Logistic regression analyses were performed, adjusting for age, sex, and sun exposure. Results: Facial melasma was identified in 66.0% of participants (n = 208), and nuclear cataracts were significantly associated with melasma (adjusted odds ratio, 2.590; 95% confidence interval, 1.410–4.770; p = 0.002). Additionally, melasma severity correlated with nuclear cataract severity (ρ = 0.186, p = 0.001). Other ocular conditions were not significantly associated with melasma. Conclusions: These findings suggest a shared UV-related pathogenesis between facial melasma and nuclear cataracts. Sun protection measures, including regular sunscreen use, UV-blocking eyewear, and wide-brimmed hats, may help mitigate the risk of both conditions. Further multicenter studies are warranted to confirm these findings and explore the underlying mechanisms. Full article

Background: Aim of the study is to analyze the trends and outcomes in Left Ventricular Assist Device (LVAD) placements between the years 2016 and 2022 using the National Inpatient Sample (NIS). Methods: Using the NIS for the years 2016–2022, we identified the total number of LVAD placements using the PCS 10 code 02HA0QZ. In-hospital outcomes and healthcare resource utilization burden were assessed. Stratification of outcomes with Extracorporeal Membrane Oxygenation (ECMO) support were performed for the years 2018–2022. Outcome analysis variance in admissions requiring ECMO support was performed using multivariate regression analysis. A two tailed p-value < 0.05 was used to determine statistical significance. Results: A general decreasing trend was observed in the total number of LVAD placements, with 852 total admissions requiring LVAD placements identified in 2016 compared to 665 in 2022. The admissions for LVAD placements requiring ECMO support had an increasing trend, with 2.21% of admissions needing ECMO support in 2018 compared to 12.18% in 2018. After multivariate regression analysis, the association between all-cause mortality during the hospital stay for LVAD placements and requirement of ECMO was found to be significant, with an odds ratio of 2.34 (1.83–4.42, p-value: 0.001). Conclusions: A general decreasing trend in LVAD placements was observed between 2016 and 2022. All-cause mortality and hospital charges during the admission had a stable trend over the years. The requirement of ECMO support had an increasing trend from 2018 to 2022. Requirement of ECMO support during the admissions for LVAD placements had a statistically significant association with all-cause mortality during the admission. A 11.50% readmission rate was observed in the 30 days following discharge, with heart failure being the major cause of readmission. Full article

Background: Morbidity and mortality rates in intensive care units (ICUs) reflect the severe health challenges faced by critically ill patients. Nutritional and immune status, as measured by the prognostic nutritional index (PNI), are increasingly recognized as important predictors of intensive care unit outcomes. Objective: We aimed to compare the prognostic nutritional index levels of survived and deceased subjects treated in intensive care units. Methods: This retrospective study examined the association between prognostic nutritional index and mortality among intensive care unit patients treated from June 2023 to June 2024. The prognostic nutritional index was calculated using serum albumin and lymphocyte levels, and patients were categorized into survived and deceased groups. Statistical analyses, including ROC and logistic regression, were used to evaluate prognostic nutritional index’s predictive capacity. Results: We revealed that deceased patients had significantly lower prognostic nutritional index values, lower platelet counts, and higher C-reactive protein (CRP) and serum creatinine levels compared to survivors. The prognostic nutritional index was independently associated with mortality, with each unit increase decreasing mortality risk by 6%. Conclusion: These findings highlight the prognostic nutritional index’s utility as a prognostic tool in intensive care unit settings, underscoring the need for nutritional assessments and targeted interventions to improve patient outcomes. Further research with larger cohorts is warranted to validate these findings and explore causative mechanisms. Full article

Background: Supraventricular tachycardia (SVT) is a common arrhythmia requiring prompt intervention in the emergency department (ED). Despite evidence-based guidelines recommending a stepwise approach, significant variability in clinical practice persists, particularly in adenosine dosing strategies. Objective: This study assessed adherence to SVT treatment protocols in the ED, focusing on the efficacy of an initial 6 mg versus 12 mg adenosine dose and the use of alternative pharmacologic agents. Methods: This multi-center, retrospective cohort study analyzed adult patients (≥18 years) diagnosed with stable SVT in urban EDs across North Texas between 1 January 2019, and 16 January 2022. Patients who spontaneously converted to normal sinus rhythm or presented with hemodynamically unstable SVT requiring immediate cardioversion were excluded. The primary outcome was the rate of successful conversion to sinus rhythm. Secondary outcomes included frequency of adenosine administration, deviations from 2020 AHA ACLS guidelines in SVT treatment, and risk factors associated with failure to convert to sinus rhythm following adenosine administration. Results: A total of 439 patients were included in the final analysis. Vagal maneuvers were attempted in 26% of cases, achieving a 31% success rate. Adenosine was used in 83% of pharmacologic interventions, with 57.5% receiving 6 mg and 42.5% receiving 12 mg as the initial dose. The 12 mg dose had a significantly higher conversion rate (54.2% vs. 40.6%, p = 0.03). Regression analysis identified key predictors of treatment success, including comorbidities, and baseline hemodynamics. Documentation inconsistencies, particularly regarding vagal maneuvers, were noted. Conclusions: In our cohort, an initial 12 mg adenosine dose was more effective than 6 mg for SVT conversion in the ED. Recognizing and addressing variations in guideline adherence can play a key role in improving patient care. Further prospective research is warranted to optimize dosing strategies and evaluate the impact of standardized protocols on clinical outcomes. Full article

Introduction: Placebo-controlled studies are crucial in clinical trials, but the placebo effect can vary across conditions. We aimed to assess the placebo effect in chronic thromboembolic pulmonary hypertension (CTEPH) trials. Methods: We conducted a systematic review and included randomized placebo-controlled trials investigating CTEPH interventions. Primary outcomes were the pre–post changes in the 6 min walk test (6MWT) and quality of life in the placebo arms. Secondary outcomes included mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), cardiac index, and NT-proBNP levels. Meta-analyses were performed using random-effects models. Results: Seven trials with 270 CTEPH patients in placebo arms were analyzed. The average 6MWT change was not significant (−1.31 m; 95%CI −12.49 to +9.79). Quality of life with EQ-5D was not significantly improved (−0.04; 95%CI −0.10 to +0.02). mPAP, PVR, cardiac index, and NT-proBNP also demonstrated non-significant changes with small magnitudes. Conclusions: The placebo effect in CTEPH trials was not statistically significant and had small magnitude but should not discourage the use of placebo-controlled trials where applicable and ethical.

Background/Objectives: Emotional eating has been considered as a trend to consume energy concentrated and tasty foods in response to adverse emotions. Emotional eating may harmfully influence physical and mental health among university students, worsening their daily quality of life and their academic performance. The aim of the present study is to critically summarize and analyze the currently available clinical data concerning the impact of emotional eating among university students. Methods: Comprehensive exploration of the currently available scientific literature was performed in the most precise scientific databases, utilizing relevant and representative keywords. Results: More than a few interrelationships were found between emotional eating and body mass index, physical activity, depression, anxiety, stress, social media overuse, nutritional behaviors, and COVID-19 lockdown concerning university students. Conclusions: The currently available clinical studies support evidence that there are significant intercorrelations between emotional eating and several aspects of physical and mental health of university students. However, most of them have a cross-sectional design that cannot establish causality effects. In this respect, prospective surveys are strongly required to delineate the impact of emotional eating in the daily life of university students. Full article

Background/Objectives: Inflammatory bowel disease (IBD) includes Crohn’s disease (CD) and ulcerative colitis (UC). The availability of an increasing number of new molecules approved for IBD treatment has increased our ability and aspirations to change the trajectory of the disease. The Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) II consensus (2018) is the current suggested strategy for IBD management, which recommends a treat-to-target approach. The primary objective of this study is to describe the clinical history of IBD in the post-STRIDE II era and to quantify the burden of IBD in terms of hospitalisation rate. The secondary objective is to estimate the 6-year risk of intestinal resection among IBD patients. Methods: A population-based time series analysis was conducted on administrative data; retrospective data from January 2011 to December 2021 were collected for the Local Health Authority “Roma 1” population (∼1.5 million residents). Hospitalisation and surgical events were prospectively recorded for patients newly diagnosed between January 2018 and February 2022 (n = 556), with follow-up throughout May 2024. A Kaplan–Mayer survivor analysis was performed to estimate the cumulative surgery risk. Results: In 2021, the IBD prevalence was 218.3 cases/100,000 people (77.2 CD, 141.1 UC). The incidence trend slowly increased during the last decade, up to 5.3 (CD) and 9.4 (UC) cases/100,000 ppl/year. The yearly hospitalisation rate remained stable, near 16.5%. The 6-year cumulative risk of surgery was 36% for CD and 20% for UC. Conclusions: The incidence of IBD has increased in the last few decades, with substantial stability in regard to the incidence of surgery and hospitalisations. Thus, the current IBD management approach has only had a small effect on changing the natural history of the disease. Full article

Background/Objectives: Indocyanine green fluorescence angiography (ICG-FA) enables the real-time visualization of tissue perfusion. However, objective research on microscope-integrated fluorescence angiography (FA) has not been conducted before. This study aims to evaluate the fluorescence light distribution in images formed by ICG-FA in two surgical microscopes using a phantom, and to provide recommendations for their application. Methods: An 11.8 by 6.8 cm ICG and Intralipid phantom was made to evaluate overall spatial fluorescence sensitivity in two surgical microscopes in multiple working distances (WDs) and magnification factors (MFs). The signal was quantified using a tailor-made software in Python 3.8.10. Results: A clear center–periphery effect was present in most settings in both microscopes, with the highest peripheral fluorescence signal loss in the lowest MF: 100% in the Tivato and 83% in the Pentero. Increasing the MF improved homogeneity, where the biggest difference was seen between the first and second MF. A 30 cm WD and 3.5× MF produced the most homogeneous images suitable for free-flap surgery. Manually opening the light beam diameter also reduced the center–periphery effect. Conclusions: Peripheral signal loss in microscope-integrated ICG-FA must be considered during clinical interpretation and for the quantification of tissue perfusion. In clinical practice during reconstructive free-flap surgery, a 30 cm WD, 3.5 MF, and manually opened light beam diameter should be applied to achieve the most homogeneous image. Full article

Background/Objectives: Diabetic ketoacidosis (DKA) is a common acute complication of diabetes with treatment consisting of reversal of cause, insulin administration, fluid resuscitation and electrolyte repletion. Yet, many aspects of DKA management are currently based on low-quality evidence or physiological rationale. This evidence and gap map review presents an overview of the current body of literature and identifies evidence gaps in relation to therapeutic interventions for DKA. Methods: Interventions and outcomes relevant to DKA were identified and iteratively developed to produce a coding model for the proposed evidence and gap map. PubMed was searched with Me SH terms relevant to the identified interventions and outcomes. Studies identified were screened and assigned interventions and outcomes. Interventional research was uploaded to EPPI-Reviewer and EPPI-Mapper to produce the evidence and gap map. Results: The search identified 1131 studies, of which 18 were non-human and 345 were duplicates. A total of 768 unique studies were screened, and 118 were identified as interventions (52 pediatric and 66 adult studies). A total of 26 high-quality studies, 88 medium-quality studies and 4 low-quality studies were identified. These 118 studies were coded into the proposed DKA evidence and gap map. The intervention domains were fluid therapy, insulin therapy, electrolyte replacement, adjunct therapies and admission type. The outcome domains were DKA resolution, insulin duration, length of stay, morbidity and mortality, complications, and biochemical parameters. Conclusions: Fluid type and insulin infusion administration were prominent in the current literature. These studies frequently used DKA resolution and complications associated with DKA such as electrolyte disturbances and cerebral edema as the primary outcomes. Substantial gaps were identified with scant evidence to guide prophylactic electrolyte administration, enteral intake and adjunctive therapy (thiamine, bicarbonate). Even for well-investigated interventions such as fluids and insulin, substantial gaps existed, particularly for patient-centered and healthcare service outcomes. Full article

The Frozen Elephant Trunk (FET) technique is indicated in acute aortic syndromes with arch involvement and malperfusion of tissues. We sought to report on long-term outcomes of FET in emergent cases of acute aortic syndromes. Methods: Twenty-three adult patients were referred to our department for surgical management of acute aortic syndromes and underwent aortic arch replacement using the FET technique between November 2010 and January 2022. The primary outcome was long-term survival. Secondary outcomes were the 30-day mortality rate and the incidence of neurologic complications, i.e., stroke and spinal cord ischemia. Results: The mean patient age was 57.1 (±12.5) years, and the majority (20 patients, 87%) were male. The most common indication was Stanford type A acute aortic dissection (aTAAD) in 17 (74%) patients, followed by non-A non-B dissection in 2 (8.7%) patients, penetrating aortic ulcer (PAU) of the aortic arch in 2 (8.7%) patients, type A intramural hematoma (IMH) in 1 (4.3%) patient and blunt thoracic aortic injury of the aortic arch in 1 (4.3%) patient. Kaplan–Meier survival analysis revealed a 73% survival at 12 months, which persisted up to 11 years of follow-up. Conclusion: The FET technique provides a reliable solution for surgical management of patients with acute aortic syndromes. Excellent, sustained long-term results can be achieved. Full article

Background: Stress shielding (SS) after total hip arthroplasty (THA) leads to proximal femoral bone loss and increases the risk of complications such as implant loosening and periprosthetic fracture. While various low-stiffness stems have been developed to prevent SS, they often compromise mechanical stability. A novel femoral stem composed of Ti-33.6Nb-4Sn (TNS) alloy offers a gradually decreasing Young’s modulus from proximal to distal regions, potentially improving load distribution and reducing SS. This study aimed to evaluate the mid-term clinical and radiographic outcomes of the TNS stem, with a particular focus on its effectiveness in suppressing SS. Methods: A prospective clinical study was conducted involving 35 patients who underwent THA using the TNS stem, with a minimum follow-up of 7 years. Twenty-one patients with Ti6Al4V metaphyseal-filling stems served as controls. Clinical outcomes were assessed using Japanese Orthopaedic Association (JOA) scores, and radiographic SS was graded using Engh’s classification and analyzed in Gruen zones. Inter-examiner reliability and statistical comparisons between groups were performed using appropriate tests. Results: The TNS group showed significantly higher preoperative JOA scores than the control group, but no significant difference in final scores. Both groups demonstrated significant improvement postoperatively. Third-degree SS occurred in the TNS group, although the overall SS grade distribution was significantly lower than in the control group (p = 0.03). SS frequency was significantly reduced in Gruen Zones 2, 3, and 6 in the TNS group. Conclusions: The TNS stem demonstrated a significant reduction in SS progression compared to conventional titanium stems over a 7-year period, with comparable clinical outcomes. However, the occurrence of third-degree SS indicates that material optimization alone may be insufficient, highlighting the need for further design improvements. Full article

Background: Peak inspiratory flow rate (PIFR) measurement is an essential tool for assessing the effectiveness of inhaler therapy in chronic obstructive pulmonary disease (COPD). This study aimed to evaluate the accuracy of three different inhaler testers compared to the In-Check DIAL^® device. Methods: A cross-sectional study was conducted in clinically stable COPD patients. Participants performed PIFR measurements using the In-Check DIAL^® device and three inhaler testers (Accuhaler, Ellipta, and Turbuhaler). Optimal PIFR was defined as ≥60 L/min. Minimum PIFR was defined as ≥30 L/min. Results: A total of 82 COPD patients (93.9% male) were included, with a mean age of 73.3 ± 8.8 years. Post-bronchodilator forced expiratory volume in one second was 69.2 ± 21.0%. The prevalence of optimal PIFR was 78%, 74%, and 52% for the Accuhaler, Ellipta, and Turbuhaler testers, respectively. For detecting optimal PIFR, the Accuhaler tester demonstrated an accuracy of 80.5%, sensitivity of 100%, and specificity of 11.1%. The Ellipta tester showed an accuracy of 78.1%, sensitivity of 100%, and specificity of 14.3%, while the Turbuhaler tester achieved an accuracy of 56.1%, sensitivity of 100%, and specificity of 7.7%. All devices showed excellent accuracy (>95%), sensitivity (>98%), and specificity (100% except for the Turbuhaler tester) in detecting minimum PIFR. Conclusions: The majority of COPD patients achieved optimal PIFR across the three different devices, with the highest prevalence observed for the Accuhaler tester. All three inhaler testers demonstrated excellent accuracy in assessing PIFR in COPD patients, suggesting their potential as reliable alternatives to the In-Check DIAL^® device in clinical practice.

Background: Oral bronchodilators may serve as an adjunctive therapy in patients with chronic obstructive pulmonary disease (COPD). This study aimed to evaluate the effects of oral doxofylline and oral procaterol on lung function and clinical symptoms in COPD patients. Methods: A crossover randomized controlled trial was conducted in patients with clinically stable COPD. Participants first received either doxofylline or procaterol for 4 weeks, followed by a 1-week washout period. Assessments included the modified Medical Research Council (mMRC) dyspnea scale, COPD assessment test (CAT) scores, and 6-minute walking distance (6MWD). Pulmonary function was evaluated using spirometry with bronchodilator (BD) testing and all adverse events were recorded. Results: Twenty patients were randomly assigned to begin treatment with either doxofylline or procaterol. Their mean age was 71.7 ± 9.4 years. After four weeks of treatment, the doxofylline group showed significantly greater improvement in pulmonary function parameters (post-BD peak expiratory flow and post-BD forced expiratory flow 25–75) compared to the procaterol group. However, there were no significant differences in mMRC scores, CAT scores, or 6MWD between the two groups. More neurological adverse events were observed in the doxofylline group compared to the procaterol group (35% vs. 5%, p = 0.044). Conclusions: Doxofylline improved pulmonary function in COPD patients but did not provide superior functional performance compared to procaterol. Neurological adverse events were more frequently associated with doxofylline. Doxofylline may serve as an adjunctive therapy to enhance pulmonary function in COPD patients, but caution is advised due to its potential side effects. Full article

Respiratory virus infections, such as those caused by influenza viruses, respiratory syncytial virus (RSV), and coronaviruses, pose a significant global health burden. While the immune system’s adaptive components, including memory T cells, are critical for recognizing and combating these pathogens, recurrent infections and variable disease outcomes persist. Memory T cells are a key element of long-term immunity, capable of responding swiftly upon re-exposure to pathogens. They play diverse roles, including cross-reactivity to conserved viral epitopes and modulation of inflammatory responses. However, the protective efficacy of these cells is influenced by several factors, including viral evolution, host age, and immune system dynamics. This review explores the dichotomy of memory T cells in respiratory virus infections: their potential to confer robust protection and the limitations that allow for breakthrough infections. Understanding the underlying mechanisms governing the formation, maintenance, and functional deployment of memory T cells in respiratory mucosa is critical for improving immunological interventions. We highlight recent advances in vaccine strategies aimed at bolstering T cell-mediated immunity and discuss the challenges posed by viral immune evasion. Addressing these gaps in knowledge is pivotal for designing effective therapeutics and vaccines to mitigate the global burden of respiratory viruses. Full article

Cancer is the second leading cause of mortality worldwide. Despite the available treatment options, a majority of cancer patients develop drug resistance, indicating the need for alternative approaches. Repurposed drugs, such as antiglycolytic and anti-microbial agents, have gained substantial attention as potential alternative strategies against different disease pathophysiologies, including lung cancer. To that end, multiple studies have suggested that the antiglycolytic dichloroacetate (DCA) and the antibiotic salinomycin (SAL) possess promising anticarcinogenic activity, attributed to their abilities to target the key metabolic enzymes, ion transport, and oncogenic signaling pathways involved in regulating cancer cell behavior, including cell survival and proliferation. We used the following searches and selection criteria. (1) Biosis and PubMed were used with the search terms dichloroacetate; salinomycin; dichloroacetate as an anticancer agent; salinomycin as an anticancer agent; dichloroacetate side effects; salinomycin side effects; salinomycin combination therapy; dichloroacetate combination therapy; and dichloroacetate or salinomycin in combination with other agents, including chemotherapy and tyrosine kinase inhibitors. (2) The exclusion criteria included not being related to the mechanisms of DCA and SAL or not focusing on their anticancer properties. (3) All the literature was sourced from peer-reviewed journals within a timeframe of 1989 to 2024. Importantly, experimental studies have demonstrated that both DCA and SAL exert promising anticarcinogenic properties, as well as having synergistic effects in combination with other therapeutic agents, against multiple cancer models. The goal of this review is to highlight the mechanistic workings and efficacy of DCA and SAL as monotherapies, and their combination with other therapeutic agents in various cancer models, with a major emphasis on non-small-cell lung cancer (NSCLC) treatment.

Background: Heart transplantation (Htx) remains the definitive therapy for patients with end-stage heart failure. Despite advancements in mechanical circulatory support (MCS), immunosuppressive strategies, and organ allocation policies, donor availability remains a major limitation. This study analyzes the trends in Htx in the United States between 2016 and 2022, focusing on demographic shifts, mortality trends, and 30-day readmission patterns. Methods: We utilized the National Inpatient Sample (NIS) from 2016 to 2022 and the National Readmissions Database (NRD) for 2021 to identify Htx admissions using ICD-10 PCS code O2YA0Z0. Patient characteristics, mortality rates, and readmission patterns were analyzed using ANOVA and multivariate logistic regression, with statistical significance defined as p < 0.05. Results: The total number of Htx procedures increased from 641 in 2016 to 773 in 2022. The mean age of transplant recipients remained between 45 and 50 years, with no significant differences across years. Racial and socioeconomic disparities persisted, with approximately 60% of transplants occurring in White patients and 21–26% of recipients belonging to the lowest income quartile. All-cause in-hospital mortality remained stable at 4–7%. The 30-day readmission rate in 2021 was 57.7%, with heart failure, transplant rejection, and infections being the leading causes. Peripheral vascular disease (PVD) was the only comorbidity significantly associated with higher 30-day readmission risk (OR: 1.815, 95% CI: 1.477–2.230). Conclusions: Htx utilization has increased over time, driven by improvements in donor allocation and perioperative management. However, racial and socioeconomic disparities remain, and readmission rates continue to be high. Future efforts should focus on optimizing post-transplant care and addressing disparities to improve long-term outcomes. Full article

Background: Upper Gastrointestinal Bleed (UGIB) is a common and potentially life-threatening condition with an annual incidence of 80–150 per 100,000 individuals and a mortality rate of 2–10%. Esophagogastroduodenoscopy (EGD) is the gold standard for both diagnosis and treatment, but post-discharge outcomes, including readmissions, remain underexplored. Methods: This study utilized the 2021 National Readmission Database (NRD) to analyze 30-day readmission rates following EGD for UGIB. Adult patients (≥18 years) admitted for UGIB and undergoing EGD were included; those who died during the index hospitalization were excluded. Demographic, clinical, and socioeconomic factors associated with readmission were examined using multivariate logistic regression. Results: Among 34,257 patients admitted for UGIB and undergoing EGD, 11,088 (32.4%) were readmitted within 30 days, with 5423 (49%) due to recurrent UGIB. Readmitted patients had a higher mean age (68.46 vs. 67.63 years) and greater prevalence of cirrhosis (16.71% vs. 13.84%). Hospital resource utilization was significantly higher among readmissions, with increased total hospital charges (USD 82,544.82 vs. USD 61,521.17) and longer hospital stays (5.38 vs. 4.97 days). Mortality was lower among readmitted patients (1.46% vs. 3.53%). Multivariate analysis identified cirrhosis (OR 7.20, 95% CI: 6.45–8.02), untreated H. pylori infection (OR 3.43, 95% CI: 2.15–4.30), atrial fibrillation (OR 1.52, 95% CI: 1.36–1.69), and chronic antithrombotic therapy (OR 1.63, 95% CI: 1.41–1.89) as significant predictors of recurrent UGIB readmission. Lower socioeconomic status was also associated with increased readmission risk (OR 1.15, 95% CI: 1.05–1.25). Conclusions: Readmission following EGD for UGIB is common and driven primarily by recurrent bleeding. Cirrhosis, untreated H. pylori infection, atrial fibrillation, and chronic anticoagulation therapy are key risk factors. These findings highlight the need for targeted interventions, including improved post-discharge management and optimization of anticoagulation strategies, to reduce readmission rates and improve patient outcomes.

Background: Hashimoto’s thyroiditis (HT) is the most common autoimmune thyroid disease (AITD) and is characterized by the presence of thyroid autoantibodies against thyroid peroxidase and/or thyroglobulin. Several studies have found that the global prevalence of HT has increased in recent decades, while others show the opposite. Methods and Results: The objective of this scoping review was to synthesize and analyze the different studies that have evaluated the prevalence of HT (in adults) and the possible associated factors. The following databases were consulted, as follows: MEDLINE, Web of Science, PubMed, and Scopus. The search terms “epidemiology”, “prevalence”, and “Hashimoto disease” and “Hashimoto thyroiditis” were used. The search was limited to articles published between January 1965 and October 2024, and only articles in English were considered. In order to reduce selection bias, each article was scrutinized using the JBI Critical Appraisal Checklist independently by two authors. Studies were included if the number of participants (study population and/or cases and controls, depending on the study design) was clearly described and duplicate studies were excluded. A total of 59 studies were identified, the vast majority of them used a cross-sectional design, using different methods of disease assessment. Conclusions: Globally, the prevalence of HT is estimated to be between 5–10%; some areas with prevalences > 20% and others < 0.5% were identified. Prevalence is also higher in women than in men. Multiple underlying factors (genetic, epigenetic, environmental, and lifestyle), together with socioeconomic, nutritional, overdiagnosis, inter alia, may explain (at least in part) the wide variability in the prevalence of HT.

Purpose: To evaluate the potential clinical role and reliability of Sonazoid-enhanced ultrasound (SEUS) as a diagnostic tool for liver metastatic lesions. Methods: An extensive literature search was conducted across five electronic databases, PubMed, Scopus, Embase, Cochrane Library, and Web of Science, from their inception up to January 2024 to identify all studies evaluating the use of Sonazoid-enhanced ultrasonography for detecting hepatic metastases. A meta-analysis was performed to assess diagnostic accuracy using the Meta-DiSc 2.0 software. Results: A total of 31 studies were included, 16 of which were eligible for meta-analysis and diagnostic test accuracy evaluation. A total of 13 studies in the meta-analysis evaluated the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) for 1347 metastatic and 1565 non-metastatic liver lesions. The pooled sensitivity and specificity for CEUS were 0.88 (95% CI: 0.82–0.92) and 0.92 (95% CI: 0.84–0.96), respectively. The combined positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 11.89 (95% CI: 5.42–26.09), 0.12 (95% CI:0.08–0.19), and 91.99 (95% CI: 32.15–263.17), respectively. Additionally, four studies of the meta-analysis assessed the diagnostic performance of contrast-enhanced intraoperative sonography (CE-IOUS) in detecting 664 metastatic and 246 non-metastatic liver lesions. The pooled sensitivity and specificity for CE-IOUS were 0.93 (95% CI: 0.82–0.97) and 0.84 (95% CI: 0.65–0.93), respectively. The aggregated positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were calculated as 5.95 (95% CI: 2.32–15.25), 0.07 (95% CI: 0.02–0.24), and 77.68 (95% CI: 10.33–583.86), respectively. Conclusions: CE-IOUS and CEUS are reliable approaches for diagnosing liver metastatic lesions. CE-IOUS, in particular, exhibits higher accuracy in identifying liver metastatic lesions, indicating its potential effectiveness in clinical practice. Full article

Introduction: Pediatric cancer survivors are at high risk for visual–motor and cognitive deficits that persist throughout life. These domains are related to academic performance. The current study examined (i) whether both visuomotor and cognitive functions and (ii) whether visuomotor functions alone mediate the relationship between age and cognitive functions. Methods: In total, there were 210 participants (7–17 years): 70 posterior fossa tumors (M_age = 12.1 ± 3.2 years, 44% female) and 70 acute lymphoblastic leukemia (M_age = 12.3 ± 3.4 years, 45% female) survivors and 70 (M_age = 12.2 ± 3.3 years, 41% female) healthy controls. Visual motor integration, motor coordination and visual perception were assessed using the Beery VMI test. Working memory, attention and planning were assessed using CANTAB. Results: Impaired motor function is significantly more pronounced than cognitive impairment in both groups of cancer survivors (effect size from 25 to 30% for visual–motor and from 5 to 7% for cognitive functions). A multiple regression model revealed that age and visual motor functions are significant predictors of attention (in the ALL group β = −0.490, t = −4.88, p = 0.000) and working memory (in the PFT group β = 0.264, t = 2.72, p = 0.008; in the ALL group β = 0.215, t = 2.24, p = 0.028). Conclusions: In children who have experienced acute lymphoblastic leukemia and tumors of the posterior cranial fossa, visual–motor dysfunction is more pronounced than cognitive impairment. In addition, there is an association between visual–motor function disorders and working memory. These findings can be used to develop more specific rehabilitation protocols. Full article

Background: Ischemic heart disease (CAD), a leading global health burden, arises primarily from atherosclerosis, an inflammatory condition characterized by lipid accumulation and metabolic dysregulation. The precise contribution of inflammatory cytokines (IL-2, IL-6, and TNF-α) to CAD pathogenesis remains an area of significant research. Aim: The primary aim of this study is to examine the IL-2, IL-6, and TNF-α in patients with coronary artery disease (CAD) and compare them with Non-CAD individuals to evaluate their potential as diagnostic biomarkers for CAD. Methodology: A prospective observational study was conducted over 3 years, involving 100 participants divided into CAD and non-CAD groups. Blood samples were isolated and analyzed for IL-2, IL-6, and TNF-α levels utilizing ELISA kits. Biochemical parameters, including lipid profiles, were also assessed. Results: This study observed significantly elevated IL-6 in patients with CAD compared with controls, while IL-2 and TNF-α levels did not reach statistical significance. The CAD group exhibited dyslipidemia characterized by elevated triglycerides and reduced HDL. Furthermore, the CAD group demonstrated alterations in biochemical parameters, including lower albumin and calcium levels, higher urea and uric acid levels, and an elevated erythrocyte sedimentation rate. These findings suggest a systemic inflammatory state and metabolic disturbances in patients with CAD. Conclusions: This study highlights IL-6 as a potential biomarker and key player in CAD pathogenesis. These findings warrant further investigation into the therapeutic potential of targeting inflammatory pathways for cardiovascular risk reduction. Full article

This study aimed to evaluate the practicality and feasibility of using intracavitary electrocardiography to confirm the proper placement of a central venous catheter for hemodialysis. Central venous catheters are typically placed using an echo-guided technique based on anatomical landmarks, followed by X-ray confirmation. Anesthesiology guidelines recommend evaluating the intracavitary electrocardiogram during the procedure to verify the correct CVC placement. This study involved 11 patients without rhythm disturbances, in whom a central venous catheter was placed in the right internal jugular vein at our institute in 2024. The patient’s electrocardiogram was analyzed using the MAGELLANO^® (Italy) device to identify changes in the P wave or QRS complex, which confirmed the CVC’s correct placement at the right cavoatrial junction. Thoracic ultrasound was used to identify the right internal jugular vein and exclude iatrogenic pneumothorax. A subsequent chest X-ray was performed to further confirm the correct placement. In addition, a non-systematic review of the most recent literature on this topic was conducted using the Database PubMed—United States National Library of Medicine. Chest X-ray consistently verified the correct placements identified by ECG-IC, with no post-procedure complications. ECG-IC is a straightforward, viable, and cost-effective technique with high sensitivity when administered by properly trained professionals. This approach, combining ultrasound-guided CVC placement in the right internal jugular vein and intracavitary ECG monitoring, can omit X-ray control in more than 90% of cases. Full article

Objectives: This study aimed to evaluate the incidence of adverse reactions to the COVID-19 vaccine among pregnant and breastfeeding women and identify associated demographic and clinical factors. Methods: A cross-sectional study was conducted at a hospital in Hanoi, Vietnam, from November 2021 to March 2022. A total of 1204 participants, including 991 pregnant women beyond 13 weeks of gestation and 213 breastfeeding women, were recruited through convenience sampling. Data were collected using a self-administered questionnaire designed to capture demographic information and adverse reactions occurring within seven to 28 days post-vaccination. Statistical analyses, including chi-square tests, Fisher’s exact tests, and logistic regression, were performed using Stata 16.0, with the significance set at p < 0.05. Results: The most common adverse reactions were localized pain at the injection site (26.2%), dizziness and fatigue (19.2%), and fever below 39 °C (29.1%). Severe adverse reactions, such as a tight throat, coma, and premature birth, were rare. A multivariate analysis identified the significant factors associated with the adverse reactions, including age (aOR = 2.04 for participants aged 36–40 years), occupation (lower odds for farmers and business professionals), urban residency (aOR = 0.64), and a history of allergies (aOR = 1.59). Education level, number of children, and gestational age were not significantly associated with adverse events. Conclusions: The findings support the safety of the COVID-19 vaccine in pregnant and breastfeeding women, with most of the adverse reactions being mild and self-limiting. Full article

India’s population complexity presents varied challenges in genetic research, and while facilities have gained traction in tier-1 and -2 cities, reliance on international collaborations often delays such investigations. COVID-19 further exacerbated the issues with such sample sharing. Congenital Hyperinsulinism (CHI) is a rare genetic disorder of pancreatic β-cells causing hypoglycaemia in children due to abnormal insulin secretion. Given India’s high birth rate and consanguineous populations, annual CHI cases are estimated to be around up to 10,000, with up to 50% having unexplained genetic causes. Diffuse or atypical lesions in such patients often necessitate near-total-pancreatectomy, risking pancreatic exocrine insufficiency and diabetes, requiring lifelong therapy. Also, novel genetic variations complicate accurate diagnosis, risk assessment, and counselling, emphasising the need for rapid genetic assessment to prevent neurological injuries and inform treatment decisions. Despite significant efforts at many institutes, there are no dedicated organisations for CHI in India. With the implementation of the National Policy for Rare Diseases 2021, we plan to form a non-profit organisation, “Congenital Hyperinsulinism India Association (CHIA)”, comprising paediatric endocrinologists, paediatricians, geneticists, and independent researchers. The aims of this association are to generate a national database registry of patients, formulate a parent support group and CHIA consortium, design patient information leaflets, as well as foster genomic collaborations and promote clinical trials. Such steps will help sensitise the health authorities and policy makers, urging them to improve the allocation of health budgets for rare diseases, as well as empower patients and their families, contributing towards a better quality of life.

Introduction: The use of electrical appliances using extremely low frequency (ELF) electromagnetic fields (EMF) has increased in the past few years. These ELF MF are reported to be linked to several adverse health effects. However, only a couple of studies have been conducted on the association between risk of tumours and use of electronic devices using low frequency (LF) EMF. Methods: We studied the use of common household electrical appliances and suspected risk of tumours in a multi-hospital-based case-control study. In total, 316 patients were included in the final analysis. Results: The study results showed a below unity risk for most of the devices. A slight increased risk of tumour was observed for computer screen use OR: 1.13 (95% CI: 0.43–3.02) and use of microwave oven OR: 1.21 (95% CI: 0.36–4.04). We also had chance to investigate ELF MFs exposure association with tumour. Where we observed elevated odd ratios in individuals living near electricity transformer stations, with a statistically significant risk OR: 2.16 (95% CI: 1.30–3.59). However, the risk was below unity (OR: 0.98) in individuals residing close to powerlines. Conclusion: The current study serves as a pilot study of primary data and will be helpful in future epidemiological research studies on the topic in the region. Full article

Background/Objectives: This investigation compared the therapeutic efficacy of extracellular microvesicles (MVs) derived from murine L929 sarcoma cells and murine mesenchymal stem cells (MSCs). Methods: A mouse model of acute kidney injury (AKI) was used. Results: Both MVs from L929 cells (L929-MVs) and MSCs (MSC-MVs), unlike those obtained from murine peripheral blood mononuclear cells (PBMCs), enhanced survival rates in AKI mice and significantly improved kidney function. This was indicated by decreased levels of urine albumin and serum creatinine. Furthermore, treatment with L929-MVs and MSC-MVs elevated the proportions of CD4+CD25+FOXP3+ regulatory T cells while reducing the presence of pro-inflammatory CD4+CD44+ T cells in the spleens of AKI mice. Conclusions: the results highlight the potential of tumour-derived MVs to facilitate organ repair and exert cytoprotective immunomodulatory effects. Full article

Background: Among rheumatologic diseases following therapy with immune checkpoint inhibitors (ICIs), the cases of cancer patients diagnosed as having polymyalgia rheumatica (PMR), particularly with nivolumab and pembrolizumab, has been steadily rising in published reports. Objectives: We performed a systematic review of published case reports with the aim of answering these questions: (1) Is PMR following therapy with nivolumab and pembrolizumab an adverse drug reaction (ADR)? (2) Is there a difference between cases of PMR following therapy with nivolumab and those following therapy with pembrolizumab? Methods: Based on Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, a comprehensive literature search in three main bibliographic databases: MEDLINE (Ovid interface), EMBASE, and COCHRANE Library was carried out on 27 December 2024. This systematic review has no registration number. Results: Data were extracted from 12 patients. Namely, 5 cases followed treatment with nivolumab and 7 with pembrolizumab. Validated scales for ADR assessment—such as Naranjo’s scale—were not used in 10 out of the 12 patients. Additionally, validated diagnostic or classification criteria for PMR were used in the majority of case reports related to nivolumab. On the contrary, clinical judgment alone was the rule in almost all case reports on pembrolizumab. Finally, the time interval between PMR manifestations and nivolumab/pembrolizumab therapy ranged from one to 14 cycles (fully compatible with pharmacokinetics). Conclusions: Our literature review highlighted significant methodological blurred lines in the categorization of PMR following therapy with nivolumab or pembrolizumab. Full article

Myeloid leukaemia (ML) is a cancer that occurs by the accumulation of abnormally multiplied myeloid cells in bone marrow, peripheral blood, and other related tissue. MST3 is a gene of the GCK family that has a role in apoptosis, along with other cellular functions like cellular differentiation, cell cycle, metabolism, and others. Objectives: The objectives of this study were to count RBCs and WBCs, study MST3 expression in ML and control samples, and perform an in silico correlation study on the KRAS and NRAS genes. Methods: The counting of RBCs and WBCs was carried out using a hemacytometer, the expression of MST3 was studied using RT-PCR, and a correlation study was carried out using GEPIA. Results: RBC and WBC levels in ML differed from the control levels, and the expression of MST3 was found to be upregulated in ML in comparison to controls, with a 2.90–8.65-fold change, with a significant p-value > 0.05. A positive correlation in expression was also found between MST3 and KRAS and NRAS genes, with a significant r value correlation. Conclusions: From this study, it could be deduced that MST3 might have a role in ML pathogenesis, but further research is needed to study its role in the progression of the disease. Full article
