RESUMO

Trichinosis is a common parasitic disease that affects the striated skeletal muscles, causing apoptotic and degenerative changes associated with myogenin expression in the affected myocytes. Hence, this study aimed to assess the ameliorative effects of stem cells and atorvastatin added to ivermectin on the infected myocytes during the muscular phase of murine trichinosis. 120 laboratory Swiss albino male mice were divided into 10 groups, and each group was subdivided into intestinal and muscular phases (each n = 6); uninfected control; untreated infected control; infected received ivermectin monotherapy; infected received atorvastatin monotherapy; infected received stem cells monotherapy; infected received ivermectin and atorvastatin dual therapy; infected received ivermectin and stem cells dual therapy; infected received atorvastatin and stem cells dual therapy; infected received ivermectin 0.2, atorvastatin 40, and stem cells triple therapy; and infected received ivermectin 0.1, atorvastatin 20, and stem cells triple therapy. Intestinal phase mice were sacrificed on the 5th day post-infection, while those of the muscular phase were sacrificed on the 35th day post-infection. Parasitological, histopathological, ultrastructural, histochemical, biochemical, and myogenin gene expression assessments were performed. The results revealed that mice that received ivermectin, atorvastatin, and stem cell triple therapies showed the maximum reduction in the adult worm and larvae burden, marked improvement in the underlying muscular degenerative changes (as was noticed by histopathological, ultrastructural, and histochemical Feulgen stain assessment), lower biochemical levels of serum NK-κB and tissue NO, and lower myogenin expression. Accordingly, the combination of stem cells, atorvastatin, and ivermectin affords a potential synergistic activity against trichinosis with considerable healing of the underlying degenerative sequel.

RESUMO

GOAL: Recent efforts to push hospitals to provide high-value care have relied on payment incentives. However, evidence indicates that 70% to 90% of performance improvement projects do not achieve their desired goals. Therefore, in addition to managing external industry pressures, hospitals need to develop performance improvement (PI) capabilities that enable them to capitalize on improvement opportunities, effectively develop and adopt solutions, and ensure the sustainability of improvements over time. While operational capabilities enable hospitals to produce and deliver services, more is needed to attain and sustain superior performance. Dynamic capabilities drive changes in operational capabilities to meet environmental demands. Dynamic capabilities also enable hospitals to renew and reconfigure their resources to optimize performance. This paper proposes the dynamic-capabilities framework as an appropriate way to develop and manage PI capabilities in hospitals, and it discusses the implications of shifting to a strategy that is driven by dynamic-capabilities PI. METHODS: The research team designed a semi-structured interview based on a review of the literature to understand whether hospitals were engaging in the activities outlined in the dynamic-capabilities framework. Nine study participants were recruited from a convenience sample of hospital PI staff at hospitals in Massachusetts and New Hampshire. De-identified transcripts were entered into NVivo12 qualitative data analysis software, and data were thematically indexed and coded following the principles of content analysis. PRINCIPAL FINDINGS: PI structures, improvement methodologies, and weaknesses did not vary significantly among hospitals. Most hospitals had a PI department and were more likely to adopt PI projects initiated by top management. While PI staff were trained in improvement methodologies, no programs were in place that required the rest of the hospital staff to become familiar with PI methods. Common areas of weakness were PI project selection, communication, coordination, learning from current and former PI projects, and systematic approaches to sustain improvements. PRACTICAL APPLICATIONS: Dynamic PI capabilities provide an opportunity to systematically identify improvement opportunities, seize on and learn from those opportunities, and renew and reconfigure resources to optimize performance. Ad hoc PI projects are insufficient to enable a hospital to sustain superior performance. Internal and external pressures to deliver high-value patient care and services require hospitals to exceed their current PI efforts. By developing dynamic PI capabilities, hospitals will adopt a more systematic and effective approach to PI, which will likely result in superior performance.

RESUMO

Trichinellosis is one of the global food-borne parasitic diseases that can cause severe tissue damage. The traditionally used drugs for the treatment of trichinellosis have limited efficacy against the encysted larvae in the muscular phase of the disease. Therefore, this study aimed to evaluate the role of atorvastatin and mesenchymal stem cells combined with ivermectin against different phases of Trichinella in experimentally infected mice. A total of 120 male Swiss albino mice were divided into two major groups (n = 60 of each), intestinal and muscular phases. Then, each group was subdivided into 10 subgroups (n = 6); non-infected control, infected non-treated control, infected ivermectin treated, infected atorvastatin treated, infected mesenchymal stem cells treated, infected combined ivermectin and atorvastatin treated, infected combined mesenchymal stem cells and ivermectin treated, infected combined mesenchymal stem cells and atorvastatin treated, infected combined mesenchymal stem cells and a full dose of (ivermectin and atorvastatin) treated, and infected combined mesenchymal stem cells and half dose of (ivermectin and atorvastatin) treated. Mice were sacrificed at days 5 and 35 post-infection for the intestinal and muscular phases, respectively. The assessment was performed through many parameters, including counting the adult intestinal worms and muscular encysted larvae, besides histopathological examination of the underlying tissues. Moreover, a biochemical assay for the inflammatory and oxidative stress marker levels was conducted. In addition, levels of immunohistochemical CD31 and VEGF gene expression as markers of angiogenesis during the muscular phase were investigated. The combined mesenchymal stem cells and atorvastatin added to ivermectin showed the highest significant reduction in adult worms and encysted larvae counts, the most noticeable improvement of the histopathological changes, the most potent anti-inflammatory (lowest level of IL-17) and anti-angiogenic (lowest expression of CD31 and VEGF) activities, and also revealed the highly effective one to relieve the oxidative stress (lowest level of SOD, GSH, and lipid peroxidase enzymes). These observed outcomes indicate that adding mesenchymal stem cells and atorvastatin to ivermectin synergistically potentiates its therapeutic efficacy and provides a promising candidate against trichinellosis.

RESUMO

GOAL: The COVID-19 pandemic has left a significant impact on hospitals' operations, expenses, and revenues. However, little is known about the pandemic's financial impact on rural and urban hospitals. Our main objective was to analyze how hospital profitability changed during the first year of the pandemic. We specifically studied the association between COVID-19 infections and hospitalizations and county-level variables with operating margins (OMs) and total margins (TMs). METHODS: We obtained data from Medicare Cost Reports, the American Hospital Association Annual Survey Database, and the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) for 2012-2020. Our final dataset consisted of an unbalanced panel with 17,510 observations for urban hospitals and 17,876 observations for rural hospitals. We estimated separate hospital fixed-effects models for urban and rural hospitals' OMs and TMs. The fixed-effects models controlled for time-invariant differences across hospitals. PRINCIPAL FINDINGS: In our review of the early impact of the COVID-19 pandemic on rural and urban hospitals' profits as well as trends in OMs and TMs from 2012 to 2020, we found that OMs were inversely related to the duration of hospitals' exposure to infections in urban and rural locations. In contrast, TMs and hospitals' exposures had a positive relationship. Government relief funds, a source of nonoperating revenue, apparently allowed most hospitals to avoid financial distress from the pandemic. We also found a positive relationship between the magnitude of weekly adult hospitalizations and OMs in urban and rural hospitals. Size, participation in group purchasing organizations (GPOs), and occupancy rates were positively related to OMs, with size and participation in GPOs relating to scale economies and occupancy rates reflecting capital efficiencies. PRACTICAL APPLICATIONS: Hospitals' OMs have been declining since 2014. The pandemic made this decline worse, especially for rural hospitals. Federal relief funds, along with investment income, helped hospitals remain financially solvent during the pandemic. However, investment income and temporary federal aid are insufficient to sustain financial well-being. Executives need to explore cost-saving opportunities such as joining a GPO. Small rural hospitals with low occupancy and low community COVID-19 hospitalization rates have been particularly vulnerable to the financial impact of the pandemic. Although federal relief funds have limited hospital financial distress induced by the pandemic, we maintain that the funds should have been more effectively targeted, as the mean TM increased to its highest level in a decade. The disparate results of our analysis of OMs and TMs illustrate the utility of using multiple measures of profitability.

RESUMO

BACKGROUND: In 2019, the COVID-19 pandemic emerged. Variation in COVID-19 patient outcomes between hospitals was later reported. PURPOSE: This study aims to determine whether sustainers-hospitals with sustained high performance on Hospital Value-Based Purchasing Total Performance Score (HVBP-TPS)-more effectively responded to the pandemic and therefore had better patient outcomes. METHODOLOGY: We calculated hospital-specific risk-standardized event rates using deidentified patient-level data from the UnitedHealth Group Clinical Discovery Database. HVBP-TPS from 2016 to 2019 were obtained from Centers for Medicare & Medicaid Services. Hospital characteristics were obtained from the American Hospital Association Annual Survey Database (2019), and county-level predictors were obtained from the Area Health Resource File. We use a repeated-measures regression model assuming an AR(1) type correlation structure to test whether sustainers had lower mortality rates than nonsustainers during the first wave (spring 2020) and the second wave (October to December 2020) of the pandemic. RESULTS: Sustainers did not have significantly lower COVID-19 mortality rates during the first wave of the pandemic, but they had lower COVID-19 mortality rates during the second wave compared to nonsustainers. Larger hospitals, teaching hospitals, and hospitals with higher occupancy rates had higher mortality rates. CONCLUSION: During the first wave of the pandemic, mortality rates did not differ between sustainers and nonsustainers. However, sustainers had lower mortality rates than nonsustainers in the second wave, most likely because of their knowledge management capabilities and existing structures and resources that enable them to develop new processes and routines to care for patients in times of crisis. Therefore, a consistently high level of performance over the years on HVBP-TPS is associated with high levels of performance on COVID-19 patient outcomes. PRACTICE IMPLICATIONS: Investing in identifying the knowledge, processes, and resources that foster the dynamic capabilities needed to achieve superior performance in HVBP might enable hospitals to utilize these capabilities to adapt more effectively to future changes and uncertainty.

RESUMO

PURPOSE OF REVIEW: Gout is a systemic disease from which some patients develop numerous painful tophi that adversely affect quality of life and functionality. Some patients treated with oral urate-lowering therapy are unable to maintain serum urate levels below 6 mg/dL, and these patients, thus classified as having refractory or uncontrolled gout, often require therapy with pegloticase to reduce symptoms and tophaceous burden. The objective of this expert opinion review is to summarize the available evidence supporting the use of concomitant immunomodulators with pegloticase to prevent development of anti-drug antibodies (ADAs) when treating patients with uncontrolled gout. RECENT FINDINGS: Emerging evidence suggests that adding an immunomodulator to pegloticase therapy can substantially increase response rates to double those observed in phase 3 randomized controlled trials. The combination of immunomodulation with pegloticase should be considered in routine clinical practice to improve durability of response, efficacy, and safety among patients with uncontrolled gout who otherwise have limited therapeutic options.

RESUMO

Herein, a series of N'-benzylidene-3,4-dimethoxybenzohydrazide derivatives were designed and synthesised to target the multidrug efflux pump (MATE). The antibacterial activities were screened against S. aureus, Acinetobacter, S. typhi, E. coli, and P. aeruginosa, whereas their antifungal activities were screened against C. albicans. Compounds 4a, 4h, and 4i showed the most promising antibacterial and antifungal activities. Moreover, compounds 4h and 4i being the broader and superior members regarding their antimicrobial effects were selected to be further evaluated via in vivo testing using biochemical analysis and liver/kidney histological examination. Additionally, molecular docking was carried out to attain further deep insights into the synthesised compounds' binding modes. Also, ADMET studies were performed to investigate the physicochemical/pharmacokinetics features and toxicity parameters of the synthesised derivatives. Finally, a structure-antimicrobial activity relationship study was established to facilitate further structural modifications in the future. HighlightsA series of new N'-benzylidene-3,4-dimethoxybenzohydrazide derivatives were designed and synthesised targeting the multidrug efflux pump (MATE) guided by the pharmacophoric features of the co-crystallized native inhibitor of the target protein.The newly synthesised compounds were assessed through in vitro, in vivo, and in silico approaches.Using the agar well diffusion assay, the antibacterial activities of the synthesised compounds were screened against S. aureus, Acinetobacter, S. typhi, E. coli, and P. aeruginosa, whereas, their antifungal activities were screened against C. albicans.The minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) of the synthesised compounds were investigated on variable microbial species.Compounds (4h and 4i) -as the broader and superior members regarding their antimicrobial effects- were further evaluated via in vivo testing using bio-chemical analysis and liver/kidney histological examination.A molecular docking study and ADMET in silico studies were performed.A structure-antimicrobial activity relationship study was established to facilitate further structural modifications in the future.

RESUMO

PURPOSE: The purpose of this article was to investigate the organizational and market-level variables associated with sustained superior hospital performance on Value-Based Purchasing total performance scores (TPS). METHODOLOGY: TPS for 2014 through 2017 was obtained from the Centers for Medicare & Medicaid Services Hospital Compare website. Market-level data were from the 2017 Area Health Resource File, and hospital-level data were from the 2014 American Hospital Association Annual Survey database. We specified a logistic regression model to identify significant predictors of hospitals with sustained superior performance on TPS, that is, "sustainers." PRINCIPAL FINDINGS: Only 8.4% of hospitals were classified as sustainers. Hospitals located in rural markets with a high Medicare Advantage penetration had a higher likelihood of being classified as sustainers. High RN staffing levels, lower Medicare share of inpatient days, not-for-profit ownership, and small size were all significant organizational predictors of sustained superior performance. CONCLUSIONS: Both modifiable characteristics, such as nurse staffing levels, and nonmodifiable characteristics, such as rural markets and small hospital size, are associated with the likelihood of hospitals sustaining superior performance over time. PRACTICE IMPLICATIONS: Managers need to carefully examine their staffing levels as they pursue interventions to sustain high TPS overtime. Moreover, factors such as Medicare share of inpatient days and size need to be considered when understanding barriers to sustained performance on Value-Based Purchasing domains.

RESUMO

EXECUTIVE SUMMARY: This study examines hospital characteristics associated with sustained superior performance on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) measures. We classified hospitals as sustainers if they remained in the top 25th percentile of overall patient ratings of inpatient experience from 2009 through 2013. We classified hospital characteristics as modifiable or unmodifiable. Modifiable characteristics are operational measures that hospitals can change to improve performance; these characteristics include registered nurse (RN) staffing levels, presence of hospitalists, and level of physician integration. Unmodifiable characteristics are core structural dimensions, such as hospital size and teaching status, that require substantial investment to change, as well as market-level factors such as competition and unemployment rates. Using logistic regression analysis, we found that RN staffing levels, Medicare share of inpatient days, teaching status, and market competition were significant predictors of the likelihood that a given hospital sustained high levels of patient ratings over time (i.e., the likelihood of a hospital being classified as a sustainer). Hospitals with a higher ratio of inpatient days to RN staffing and higher Medicare share of inpatient days had lower odds of being classified as sustainers.

RESUMO

The quality of physician-patient communication influences patient health outcomes and satisfaction with healthcare delivery. Yet, little is known about contextual factors that influence physicians' communication with their patients. The main purpose of this article is to examine organizational-level factors that influence patient perceptions of physician communication in inpatient settings. We used the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey and American Hospital Association data to determine patients' ratings of physician communication at the hospital level, and to collect information about hospital-level factors that can potentially influence physician communication. Our sample consisted of 2,756 hospitals. We ran a regression analysis to determine the predictors of poor physician communication, measured as the percentage of patients in a hospital who reported that physicians sometimes or never communicated well. In our sample of hospitals, this percentage ranged between 0% and 21%, with 25% of hospitals receiving poor ratings from more than 6% of patients. Three organizational factors had statistically significant negative associations with physician communication: for-profit ownership, hospital size, and hospitalists providing care in the hospital, On the other hand, the number of full-time-equivalent physicians and dentists per 10,000 inpatient days, physician ownership of the hospital, Medicare share of inpatient days, and public ownership were positively associated with patients' ratings of physician communication. Physician staffing levels are an understudied area in healthcare research. Our findings indicate that physician staffing levels affect the quality of physician communication with patients. Moreover, for-profit and larger hospitals should invest more in physician communication given the role that HCAHPS plays in value-based purchasing.

RESUMO

BACKGROUND: Efficiency has emerged as a central goal to the operations of health care organizations. There are two competing perspectives on the relationship between efficiency and organizational performance. Some argue that organizational slack is a waste and that efficiency contributes to organizational performance, whereas others maintain that slack acts as a buffer, allowing organizations to adapt to environmental demands and contributing to organizational performance. PURPOSES: As value-based purchasing becomes more prevalent, health care organizations are incented to become more efficient and, at the same time, improve their patients' experiences and outcomes. Unused slack resources might facilitate the timely implementation of these improvements. Building on previous research on organizational slack and inertia, we test whether efficiency and other organizational factors predict organizational effectiveness in improving Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings. METHODOLOGY: We rely on data from the American Hospital Association and HCAHPS. We estimate hospital cost-efficiency by Stochastic Frontier Analysis and use regression analysis to determine whether efficiency, competition, hospital size, and other organizational factors are significant predictors of hospital effectiveness. FINDINGS: Our findings indicate that efficiency and hospital size have a significant negative association with organizational ability to improve HCAHPS ratings. PRACTICE IMPLICATIONS: Although achieving organizational efficiency is necessary for health care organizations, given the changes that are currently occurring in the U.S. health care system, it is important for health care managers to maintain a certain level of slack to respond to environmental demands and have the resources needed to improve their performance.

RESUMO

BACKGROUND: Midodrine is an α-agonist prodrug of desglymidodrine used for the management of hypotension. Midodrine has demonstrated usefulness in hepatorenal syndrome. OBJECTIVE: The objective of the present work was to study the role of midodrine in patients with non-azotemic cirrhosis with tense ascites. METHODS: This prospective randomized double blind placebo-controlled study was conducted on 67 non azotemic inpatients with liver cirrhosis and tense ascites (52 men and 15 women; age range, 45-72). One patient declined to participate in the study, 33 patients were randomly assigned to take midodrine hydrochloride, and 33 patients were randomly assigned to take placebo. Out of 67 enrolled patients, 60 patients (30: in midodrine group; 30: in placebo group) completed the study and 6 patients lost to follow up. Patients were assessed for patients' characteristics, history of tapping their ascetic fluid, laboratory values, and Doppler parameters before and after the study. Average 24-h urine volume was assessed before and after the start of the study. RESULTS: significant reduction in body weight and abdominal girth was observed after 2 weeks of midodrine therapy. CONCLUSION: Midodrine appeared to be effective in lowering body weights and abdominal girths of non azotemic cirrhotic patients with tense ascites.

RESUMO

Duodenal gastrointestinal stromal tumors (D-GISTs) are a rare subtype of GISTs, accounting for only 4% to 5% of all GIST cases. This case report details the presentation, diagnosis, and management of a 48-year-old female who presented with melena and anemia and was eventually diagnosed with a D-GIST. The tumor was identified through imaging studies, and histopathology performed after surgical resection revealed a submucosal neoplasm composed of spindle cells with extensive hemorrhage and necrosis. Given the tumor's rarity and its challenging presentation, which can mimic other conditions such as pancreatic masses, the case underscores the importance of considering D-GIST in differential diagnoses of duodenal or pancreatic lesions. Surgical resection remains the cornerstone of treatment, with adjuvant therapy considered in high-risk cases to prevent recurrence.

RESUMO

Patients with chronic obstructive pulmonary disease (COPD) commonly exhibit muscle atrophy and dysfunction due to a reduction in muscle mass; and protein supplements such as chicken egg whites have been reported to improve muscle mass. The aim of this study was to evaluate the impact of physical exercise and egg white supplementation on the muscle mass of COPD patients. An experimental study was conducted among stable COPD patients at Universitas Sumatra Utara Hospital Medan, Indonesia, between August and October 2022. The patients were divided into two groups, control and interventional groups, with each patient subjected to a pre- and post-muscle mass assessment. All the patients performed respiratory endurance and upper extremity muscle strength training three times/week for a total of 12 weeks. In addition, the patients in the intervention group were also given egg white supplementation (10 eggs/day) during the period of intervention in addition to the physical training. The Wilcoxon and Mann-Whitney tests were performed to identify the significance of the difference between pre- and post-intervention and between the control and intervention groups, respectively. A total of 38 COPD patients were included in the study, 19 from each group. Our data suggested no significant difference in muscle mass of the patients in the control group before and after 12 weeks of physical exercise (pre-intervention 27.37±4.54% and post-intervention 27.68±4.5% with p=0.174). However, there was a significant muscle mass increment of patients in the intervention group upon 12 weeks of physical training and egg white supplementation (pre-intervention 27.18±4.15%, post-intervention 29.95±3.76%, p<0.001). A significant difference in muscle mass was observed between patients in the control and the intervention groups (p=0.046) after the intervention. The study highlights that physical exercise in combination with egg white supplementation may serve as potential and effective non-pharmacological treatment for muscle mass restoration in COPD patients as compared to physical exercise alone.

RESUMO

BACKGROUND: Stem cell-based therapy has received attention as a possible alternative to organ transplantation. The aim of this study was to assess the safety and efficacy of autologous transplantation of bone marrow (BM)-derived stromal cells in post-HCV liver cirrhosis patients. METHODOLOGY: 10 × 10(6) of isolated human bone marrow (HBM)-stromal cells in 10 mL normal saline were injected in the spleen of 20 patients with end-stage liver cirrhosis guided by the ultrasonography, and then patients were followed up on monthly basis for six months. RESULTS: A statistically significant decrease was detected in the total bilirubin, aspartate transaminase (AST), alanine transaminase (ALT) (p-value<0.01), prothrombin time (PT), and international normalized ratio (INR) levels (p-value<0.05), while a statistically significant increase in the albumin and PC (p-value<0.05) after follow-up. CONCLUSION: This study suggested the safety, feasibility, and efficacy of the intrasplenic injection of autologous BM stromal cells in improving liver function in Egyptian patients with cirrhosis.

RESUMO

BACKGROUND: Hospitals facing financial uncertainty have sought to reduce nurse staffing as a way to increase profitability. However, nurse staffing has been found to be important in terms of quality of patient care and nursing-related outcomes. Nurse staffing can provide a competitive advantage to hospitals and as a result of better financial performance, particularly in more competitive markets. PURPOSE: In this study, we build on the Resource-Based View of the Firm to determine the effect of nurse staffing on total profit margin in more competitive and less competitive hospital markets in Florida. METHODOLOGY/APPROACH: By combining a Florida statewide nursing survey with the American Hospital Association Annual Survey and the Area Resource File, three separate multivariate linear regression models were conducted to determine the effect of nurse staffing on financial performance while accounting for market competitiveness. The analysis was limited to acute care hospitals. FINDINGS: Nurse staffing levels had a positive association with financial performance (ß = 3.3, p = .02) in competitive hospital markets, but no significant association was found in less competitive hospital markets. PRACTICE IMPLICATIONS: Hospitals in more competitive hospital markets should reconsider reducing nursing staff, as these cost-cutting measures may be inefficient and negatively affect financial performance.

RESUMO

Methods and Results: The study included 200 Egyptian subjects. They were divided into four equal groups: group 1: obese patients with NAFLD and T2DM (O+/NAFLD+/DM+), group 2: nonobese patients with NAFLD and T2DM (O-/NAFLD+/DM+), group 3: obese nondiabetic patients with NAFLD (O+/NAFLD+/DM-), and group 4: nonobese healthy control subjects. Plasma adiponectin was measured using ELISA (enzyme-linked immunosorbent assay) technique. Ultrasonography was used to diagnose NAFLD. CIMT was assessed using Doppler ultrasonography. Plasma adiponectin was significantly lower and CIMT was significantly higher in O+/NAFLD+/DM+, as compared with O-/NAFLD+/DM+, O+/NAFLD+/DM-, and control subjects (p < 0.001 for all). A significant negative correlation was found between adiponectin and CIMT in obese patients with NAFLD (p < 0.05), but not in patients with NAFLD and T2DM. The significant independent predictors of CIMT were diabetes duration, BMI (body mass index), albumin/creatinine ratio, and cholesterol. Conclusion: Plasma adiponectin is inversely correlated with CIMT in obese patients with NAFLD, but not in patients with NAFLD and T2DM. Hypoadiponectinemia could be a good indicator of cardiovascular risk in obese patients with NAFLD, with or without T2DM, but not in nonobese patients with NAFLD.

RESUMO

Purpose: The cow's milk-related-symptom-score (CoMiSS) tool was developed as an awareness tool for the assessment of cow's milk-related symptoms in infants or children. Fecal calprotectin (FC) is a noninvasive biomarker of gut inflammation that can be measured in serum and stool. This study aimed to investigate the relationship between FC levels and CoMiSS scores in infants with cow's milk protein allergy. Methods: Infants (aged 6-12 months) who were allergic to cow's milk protein were enrolled prospectively. Following completion of the CoMiSS scoring, the infants were divided into group 1 (positive CoMiSS scores ≥12) and group 2 (negative CoMiSS scores <12). FC was measured using immunoassay. Results: Of the 120 infants enrolled in this study, 60 (50.0%) had positive CoMiSS scores (group 1), while 60 (50.0%) had negative scores (group 2). The mean FC level was higher in the infants in group 1 than those in group 2 (2,934.57 µg/g vs. 955.13 µg/g; p<0.001). In addition, there was a positive correlation between FC and CoMiSS scores (R=0.168, p<0.0001). A FC level of 1,700 µg/g provided a sensitivity of 98.3%, specificity of 93.3%, and accuracy of 95.8% for the diagnosis of cow's milk protein allergy (CMPA). Conclusion: FC measurement may have a role in the assessing infants with CMPA.

RESUMO

In light of increasing NAFLD prevalence, early detection and diagnosis are needed for decision-making in clinical practice and could be helpful in the management of patients with NAFLD. The goal of this study was to evaluate the diagnostic accuracy of CD24 gene expression as a non-invasive tool to detect hepatic steatosis for diagnosis of NAFLD at early stage. These findings will aid in the creation of a viable diagnostic approach. METHODS: This study enrolled eighty individuals divided into two groups; a study group included forty cases with bright liver and a group of healthy subjects with normal liver. Steatosis was quantified by CAP. Fibrosis assessment was performed by FIB-4, NFS, Fast-score, and Fibroscan. Liver enzymes, lipid profile, and CBC were evaluated. Utilizing RNA extracted from whole blood, the CD24 gene expression was detected using real-time PCR technique. RESULTS: It was detected that expression of CD24 was significantly higher in patients with NAFLD than healthy controls. The median fold change was 6.56 higher in NAFLD cases compared to control subjects. Additionally, CD24 expression was higher in cases with fibrosis stage F1 compared to those with fibrosis stage F0, as the mean expression level of CD24 was 7.19 in F0 cases as compared to 8.65 in F1 patients but without significant difference (p = 0.588). ROC curve analysis showed that CD24 ∆CT had significant diagnostic accuracy in the diagnosis of NAFLD (p = 0.034). The optimum cutoff for CD24 was 1.83 for distinguishing patients with NAFLD from healthy control with sensitivity 55% and specificity 74.4%; and an area under the ROC curve (AUROC) of 0.638 (95% CI: 0.514-0.763) was determined. CONCLUSION: In the present study, CD24 gene expression was up-regulated in fatty liver. Further studies are required to confer its diagnostic and prognostic value in the detection of NAFLD, clarify its role in the progression of hepatocyte steatosis, and to elucidate the mechanism of this biomarker in the progression of disease.
