Thirty-day outcomes of endovascular repair of Stanford type B aortic dissection in patients with chronic obstructive pulmonary disease.

Thoracic Endovascular Aortic Repair (TEVAR) has revolutionized the surgical treatment for Stanford type B aortic dissection (TBAD). While chronic obstructive pulmonary disease (COPD) is associated with worse outcomes in major surgeries, the specific outcomes of TEVAR in patients with COPD have not been extensively explored. This study aimed to evaluate the 30-day postoperative outcomes of COPD patients undergoing TEVAR for TBAD utilizing data from a multi-institutional national registry. Patients who underwent TEVAR for TBAD were identified in the ACS-NSQIP database from 2005 to 2022. A 1:3 propensity-score matching was used to match demographics and preoperative characteristics between patients with and without COPD. Thirty-day postoperative outcomes were compared. There were 172 (9.56%) and 1628 (90.44%) COPD and non-COPD patients who underwent TEVAR for TBAD, respectively. Patients with COPD had a higher comorbidity burden. After the propensity-score matching, all 172 COPD patients were matched to 440 non-COPD patients. COPD and non-COPD patients had comparable mortality rates (10.12% vs 6.82%, p = .18). However, COPD patients had a higher risk of pulmonary complications (20.83% vs 13.18%, p = .02). All other 30-day outcomes were similar between the two groups. COPD patients had 58.04% higher pulmonary complications while all other 30-day outcomes were comparable to their non-COPD counterparts. Therefore, close monitoring and timely intervention for pulmonary complications in COPD patients can be important after TEVAR for TBAD. Future studies should investigate long-term outcomes among these COPD patients.

Formation of advanced glycation end products in glucose-amino acid models of Maillard reaction under dry- and wet-heating conditions.

Advanced glycation end products (AGEs) are compounds formed by non-enzymatic processes in the Maillard reaction and can cause various chronic diseases. This study explores the AGE formation process in a glucose-amino acid system under both wet- and dry-heating conditions, and analyzes the effect of cysteine in AGE formation. Under wet-heating conditions, Nε-carboxymethyllysine (CML) and Nε-carboxyethyllysine (CEL) concentrations rose for the initial 90 min and subsequently declined after 120 min; after 90 min of heating, the maximum yields in the absence of cysteine were 1151.04 ± 14.01 and 3386.90 ± 26.55 ng mL-1, respectively. The concentration of pyrraline (Pyr) increased after 30 min and then decreased after 60 min with a maximum yield of 777.68 ± 23.36 ng mL-1. However, in dry-heating models, the AGE concentrations consistently increased with increasing heating time; the maximum yields for CML, CEL and Pyr were 468.66 ± 10.96, 1993.57 ± 14.81 and 1085.74 ± 58.06 ng mL-1, respectively. The addition of cysteine showed an inhibitory effect on AGE formation, especially for Pyr in the dry-heating model, with inhibition rates ranging from 17.14% to 95.60%. Although wet-heating models produced more CML and CEL, they produced less Pyr than dry-heating models. The AGE formation in wet-heating models positively correlated with the reaction rate; however, the dry-heating reaction demonstrated a more complex relationship between reaction rate and reaction protocol. Moreover, cysteine exhibited a significant inhibitory effect on AGE production, and the degree of inhibition was proportional to the cysteine concentration. This study provides important insights into the mechanisms for AGE formation under various heating conditions, such as those representing baking (dry-heating) and steaming conditions (wet-heating). © 2024 Society of Chemical Industry.

Insights of gut-liver axis in hepatic diseases: Mechanisms, clinical implications, and therapeutic potentials

With the rising prevalence of chronic liver diseases worldwide, there exists a need to diversify our artillery to incorporate a plethora of diagnostic and therapeutic methods to combat this disease. Currently, the most common causes of liver disease are non-alcoholic fatty liver disease, hepatitis, and alcoholic liver disease. Some of these chronic diseases have the potential to transform into hepatocellular carcinoma with advancing fibrosis. In this review, we analyse the relationship between the gut and liver and their significance in liver disease. This two-way relationship has interesting effects on each other in liver diseases. The gut microbiota, through its metabolites, influences the metabolism in numerous ways. Careful manipulation of its composition can lead to the discovery of numerous therapeutic potentials that can be applied in the treatment of various liver diseases. Numerous cohort studies with a pan-omics approach are required to understand the association between the gut microbiome and hepatic disease progression through which we can identify effective ways to deal with this issue.

Cost-Effectiveness of Temporary Financial Assistance for Veterans Experiencing Housing Instability.

The US Department of Veterans Affairs (VA) partners with community organizations (grantees) across the US to provide temporary financial assistance (TFA) to vulnerable veterans through the Supportive Services for Veteran Families (SSVF) program. The goal of TFA for housing-related expenses is to prevent homelessness or to quickly house those who have become homeless. To assess the cost-effectiveness of the SSVF program with TFA vs without TFA as an intervention for veterans who are experiencing housing insecurity. This study used a Markov simulation model to compare cost and housing outcomes in a hypothetical cohort of veterans enrolled in the SSVF program. Enrollees who are homeless receive rapid rehousing services, while those who are at risk of becoming homeless receive homelessness prevention services. The SSVF program with TFA for veterans who are experiencing housing insecurity. The effectiveness measure was the incremental cost-effectiveness ratio (ICER) with quality-adjusted life-years (QALYs). The model was parameterized using a combination of inputs taken from published literature and internal VA data. The model had a 2-year time horizon and a 1-day cycle length. In addition, probabilistic sensitivity analyses were conducted using 10 000 Monte Carlo simulations. The base case analyses found that the SSVF program with TFA was more costly ($35 814 vs $32 562) and yielded more QALYs (1.541 vs 1.398) than the SSVF program without TFA. The resulting ICER was $22 676 per QALY, indicating that TFA is the preferred strategy at a willingness-to-pay threshold of $150 000 per QALY. This ICER was $19 114 per QALY for veterans in the rapid rehousing component of the SSVF program and $29 751 per QALY for those in the homelessness prevention component of the SSVF program. At a willingness-to-pay threshold of $150 000 per QALY, probabilistic sensitivity analyses showed that TFA was cost-effective in 8972 of the 10 000 Monte Carlo simulations (89.7%) for rapid rehousing and in 8796 of the 10 000 Monte Carlo simulations (88.0%) for homelessness prevention only. This economic evaluation suggests that TFA is a cost-effective approach (ie, yields improved health benefits at a reasonable cost) for addressing housing insecurity for veterans enrolling in the SSVF program. Future research could examine the cost effectiveness of large, nationwide housing interventions such as this one among subpopulations of veterans such as those with certain comorbidities including severe mental illness or substance use disorders, those with chronic diseases, or those experiencing long-term housing instability vs acute loss of housing.

Prevalence of anxiety and depression disorders in patients with inflammatory bowel disease in a city in southern Brazil

Inflammatory bowel disease is a chronic disease with symptoms and possible complications that can bring disability to the patient and trigger impairment in mental health such as depression and anxiety disorder. Objective: To evaluate the prevalence of Anxiety and Depression Disorder in patients with IBD in the Inflammatory Bowel Disease outpatient clinic of UFPEL. Methodology: Applied socio-economic questionnaire, M.I.N.I. instrument and collection of data from the medical record during the medical consultation. In patients attending the FAMED-UFPEL outpatient clinic with a diagnosis of Inflammatory bowel disease and over 16 years of age in the period from 06/01/2021 to 02/28/2022. Results: During the exposed period, 59 patients diagnosed with IBD were evaluated, being 37 (62.7%) with Crohn's Disease and 22 (37.3%) with Ulcerative Colitis, the average age was 46 years. In the current study, disease activity was evaluated using the Mayo Score for patients with ulcerative colitis with a result with no statistical significance for depression (p:0,494) and anxiety disorder (p:0,484). The Harvey Bradshaw Score was used in patients with Crohn's Disease that also has no statistical relevance for depression (p:0.969) and anxiety disorder (p:0.380). In the present study, 29.4% of patients had Ulcerative Colitis and recurrent depressive episode and 54.2% of patients had generalized anxiety disorder. Conclusion: there is a high prevalence of mood disorders in the population studied, it is emphasized the need for the active search of these diagnoses in this population, offering adequate treatment of the pathologies found with a view to better quality of life.

Manifestations of and factors influencing posttraumatic growth among Chinese Crohn's disease patients: a qualitative exploration.

This qualitative study aims to explore the manifestations of posttraumatic growth among Chinese patients with Crohn's disease from a cultural perspective and to identify the factors influencing it. A descriptive qualitative research method was used. Semistructured interviews were conducted with 19 patients with Crohn's disease from several hospitals in Hangzhou, Zhejiang Province, China, and the China Crohn's and Colitis Foundation. There were five key manifestations of posttraumatic growth experienced by Chinese patients with Crohn's disease: improving interpersonal relationships, enhancing personal strengths, changing life priorities, expanding possibilities and gaining religious faith. Posttraumatic growth among patients was predominantly influenced by individual factors, the disease condition and social support. The findings regarding the manifestations of and factors influencing posttraumatic growth in Chinese patients with Crohn's disease are consistent with those in previous studies in patients with chronic diseases. However, our study underscores the multifaceted impact of Chinese cultural characteristics on posttraumatic growth among Crohn's disease patients. These findings can offer valuable guidance for future complex interventions and relevant clinical studies conducted within the Chinese population.

Highly Effective Modulator Therapy: Implications for the Microbial Landscape in Cystic Fibrosis

Cystic fibrosis (CF) is an autosomal recessive multisystem disorder caused by mutations in the cystic fibrosis conductance regulator (CFTR) anion channel. In the lungs specifically, CFTR mutations lead to changes in mucus viscosity and defective mucociliary clearance. Moreover, people with CF (pwCF) mount an insufficient immune response to invading pathogens, which predisposes individuals to chronic airway disease associated with chronic inflammation, colonization, and recurrent infections by mainly opportunistic pathogens. These chronic infections in the CF lung are typically polymicrobial and frequently harbour multidrug-resistant pathogens, making both treatment and eradication very challenging. During the last decade, the development of highly effective CFTR modulator therapy (HEMT) has led to a breakthrough in treatment options for pwCF. While the majority of pwCF now live longer and have fewer CF exacerbations, colonisation with common respiratory pathogens persists, thereby contributing to chronic inflammation and infection. Interestingly, there are limited reports examining the lung microbiome in the post-modulator era. Since ETI treatment is still quite novel and has only been used for about five years by now, this review will be one of the first discussing the current literature on the effect of ETI on CF pathogens. In addition, we will identify unanswered questions that remain from the effect of HEMT on the CF microbiome.

Probiotic, Postbiotic, and Paraprobiotic Effects of Lactobacillus rhamnosus as a Modulator of Obesity-Associated Factors

Obesity is a pandemic currently affecting the world’s population that decreases the quality of life and promotes the development of chronic non-communicable diseases. Lactobacillus rhamnosus is recognized for multiple positive effects on obesity and overall health. In fact, such effects may occur even when the microorganisms do not remain alive (paraprobiotic effects). This raises the need to elucidate the mechanisms by which obesity-associated factors can be modulated. This narrative review explores recent findings on the effects of L. rhamnosus, particularly, its postbiotic and paraprobiotic effects, on the modulation of adiposity, weight gain, oxidative stress, inflammation, adipokines, satiety, and maintenance of intestinal integrity, with the aim of providing a better understanding of its mechanisms of action in order to contribute to streamlining its clinical and therapeutic applications. The literature shows that L. rhamnosus can modulate obesity-associated factors when analyzed in vitro and in vivo. Moreover, its postbiotic and paraprobiotic effects may be comparable to the more studied probiotic actions. Some mechanisms involve regulation of gene expression, intracellular signaling, and enteroendocrine communication, among others. We conclude that the evidence is promising, although there are still multiple knowledge gaps that require further study in order to fully utilize L. rhamnosus to improve human health.

E-cigarettes and vaping, new spotlight on smoking as an old cardiovascular risk factor?

Smoking is one of the leading causes of chronic non-communicable diseases and asignificant risk factor for cardiovascular and respiratory diseases. While global tobacco consumption has decreased over the past two decades, the use of e‑cigarettes and water pipes (shisha) has surged at an alarming rate, particularly among younger individuals. E‑cigarettes do not offer acompletely risk-free alternative to traditional cigarettes, as the vast array of flavors and ease of use contribute to agrowing number of dependent users. Furthermore, they are not necessarily effective in overcoming nicotine addiction. This contribution provides an overview of the cardiovascular health impacts associated with shisha smoking and e‑cigarette vaping, with aparticular emphasis on the detrimental effects on endothelial function. The harmful biological effects of the toxic substances in these products, especially oxidative stress and inflammatory responses, are also discussed. Finally, the current state of recommendations, legal regulations, and commercial advertising are summarized.

MHealth-Based Self-Management Program for Patients With Rheumatoid Arthritis: A Pilot Randomized Controlled Study.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that gradually limits physical function and decreases quality of life (QOL). We evaluated an mHealth-based self-management program to help patients with RA improve their physical and psychological health, self-efficacy, physical activity, and QOL. The sample included 73 experimental and 69 control participants. A pilot randomized controlled design was employed to identify the effectiveness of an 8-week mHealth-based self-management program, which comprised educational modules regarding disease management and exercise, cognitive training, and motivational support through mobile messages and periodic phone calls. Knowledge of the health effects of RA, disease activity, perceived health, depression, self-efficacy for controlling symptoms, physical activity, and QOL were evaluated pre- and postintervention and after the 4-week follow-up period. This pilot study indicates that the mHealth-based program for people with RA is feasible. The mHealth self-management program improved patients' knowledge of RA, depression, self-efficacy for controlling symptoms, physical activity, and perceived health; however, disease activity and QOL did not significantly change. This pilot study demonstrates the potential of mHealth intervention as an effective program for strengthening self-management capacities in patients with RA. Trial Registration: KCT0007523.

Bexotegrast Shows Dose-dependent Integrin αvβ6 Receptor Occupancy in Lungs of Participants with Idiopathic Pulmonary Fibrosis: A Phase 2, Open-Label Clinical Trial.

Rationale: Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive disease characterized by dyspnea and loss of lung function. Transforming growth factor-beta (TGF-β) activation mediated by αv integrins is central to the pathogenesis of IPF. Bexotegrast (PLN 74809) is an oral, once-daily, dual-selective inhibitor of αvβ6 and αvβ1 integrins under investigation for the treatment of IPF. Positron emission tomography (PET) using an αvβ6-specific PET tracer could confirm target engagement of bexotegrast in the lungs of participants with IPF. Objectives: This Phase 2 study (NCT04072315) evaluated αvβ6 receptor occupancy in the lung, as assessed by changes from baseline in αvβ6 PET tracer uptake, following single dose administration of bexotegrast to participants with IPF. Methods: In this open-label, single-center, single-arm study, adults with IPF received up to 2 single doses of bexotegrast, ranging from 60 to 320 mg with or without background IPF therapy (pirfenidone or nintedanib). At baseline and approximately 4 hours after each orally administered bexotegrast dose, a 60-minute dynamic PET/CT scan was conducted following administration of an αvβ6-specific PET probe ([18F]FP-R01-MG-F2). αvβ6 receptor occupancy by bexotegrast was estimated from the changes in PET tracer uptake following bexotegrast. Pharmacokinetics, safety, and tolerability of bexotegrast were also assessed. Results: Eight participants completed the study. Total and unbound plasma bexotegrast concentrations increased in a dose-dependent manner, and regional PET volume of distribution (VT) values decreased in a dose- and concentration-dependent manner. The VT data fit a simple saturation model, producing an unbound bexotegrast EC50 estimate of 3.32 ng/mL. Estimated maximum receptor occupancy was 35%, 53%, 71%, 88%, and 92% following single 60, 80, 120, 240, and 320-mg doses of bexotegrast, respectively. No treatment-emergent adverse events related to bexotegrast were reported. Conclusions: Dose- and concentration-dependent αvβ6 receptor occupancy by bexotegrast was observed by PET imaging, supporting once-daily 160 to 320 mg dosing to evaluate efficacy in clinical trials of IPF.

Chlorogenic Acid Alleviates Inflammation and Fibrosis in a Murine Model of Bleomycin-Induced Systemic Sclerosis: A Histological Analysis

Background/Objectives: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by cutaneous and visceral fibrosis, vascular alterations, and a persistent inflammatory response. Despite advances in understanding the pathogenic mechanisms underlying SSc, current therapeutic options remain limited. Chlorogenic acid (CGA) is a polyphenol widely distributed in plants and has shown antioxidant, anti-inflammatory, and antifibrotic properties. However, its therapeutic potential in SSc has not been investigated yet. Methods: A model of SSc was established by administering bleomycin (BLM) at 100 U/kg to CD1 mice via an osmotic minipump. After fourteen days of BLM administration, CGA (60 mg/kg) was intragastric administered on consecutive days until day 20. On day 21, all mice were sacrificed. The effect of CGA was histologically evaluated by hematoxylin and eosin and Masson’s trichrome staining. Results: CGA treatment significantly attenuated dermal fibrosis in the BLM-induced mice model of SSc by reducing histopathological damage, including increased dermal thickness, inflammation, collagen deposition, and SSc-associated pulmonary fibrosis. Conclusions: The evidence shows that CGA attenuates BLM-induced SSc in a mice model and strongly suggests that CGA may be a promising compound for the treatment of SSc.

Pulmonary-delivered Anticalin Jagged-1 antagonists reduce experimental airway mucus hyperproduction and obstruction.

Mucus hypersecretion and mucus obstruction are pathogenic features in many chronic lung diseases directly linked to disease severity, exacerbation, progression, and mortality. The Jagged-1/Notch pathway is a promising therapeutic target that regulates secretory and ciliated cell trans-differentiation in the lung. However, the Notch pathway is also required in various other organs. Hence, pulmonary delivery of therapeutic agents is a promising approach to target this pathway while minimizing systemic exposure. Using Anticalin® technology, Jagged-1 Anticalin binding proteins were generated and engineered to potent and selective inhalable Jagged-1 antagonists. Their therapeutic potential to reduce airway mucus hyperproduction and obstruction was investigated ex vivo and in vivo. In primary airway cell cultures grown at air-liquid interface and stimulated with inflammatory cytokines, Jagged-1 Anticalin binding proteins reduced both mucin gene expression and mucous cell metaplasia. In vivo, prophylactic and therapeutic treatment with a pulmonary-delivered Jagged-1 Anticalin binding protein reduced mucous cell metaplasia, epithelial thickening and airway mucus hyperproduction in IL-13 and house dust mite allergen-challenged mice, respectively. Further, in a transgenic mouse model with pathophysiologic features of cystic fibrosis and COPD, pulmonary-delivered Jagged-1 Anticalin binding protein reduced hallmarks of airway mucus obstruction. In all in vivo models a reduction of mucous cells with a concomitant increase of ciliated cells was observed. Collectively, these findings support Jagged-1 antagonists' therapeutic potential for patients with muco-obstructive lung diseases, and the feasibility of targeting the Jagged-1/Notch pathway by inhalation.

Nail clubbing, a dermatologic window into underlying systemic disease – an All of Us Study

Introduction Nail clubbing is defined as distal phalanx thickening resulting in a bulbous appearance of the digit. We aimed to describe non-pulmonary medical conditions associated with nail clubbing using a cross-sectional approach. Methods We conducted a cross-sectional analysis of the All of Us Research Program, identifying nail clubbing patients by ICD-10-CM and/or SNOMED code. Nail clubbing patients with pulmonary disease (cases) were compared to nail clubbing patients without pulmonary disease (controls). Fisher’s Exact Test/Pearson’s Chi-Squared Test analyzed categorical variables. Independent Two-Sample t-Tests analyzed continuous variables. Odds ratios were analyzed with multivariate logistic regression adjusted for sociodemographic characteristics. Results In total, 85 participants had nail clubbing, of which 63.53% had a pulmonary disease vs. 36.47% of controls. Overall, across both cases and controls, 22% of patients had chronic liver disease, 17% hypothyroidism, 8% HIV infection, and 5% Graves’ disease/hyperthyroidism. Male vs. female patients with nail clubbing had decreased odds of having concurrent respiratory disease diagnosis (OR, 0.37; 95% CI, 0.14-0.92, p=0.03). Conclusion Greater than one third of patients had nail clubbing associated with a non-pulmonary systemic disease and a significant proportion were male. Consideration of a broad differential of pathologies associated with nail clubbing is needed to initiate workup and make appropriate screening referrals.

The role of nurses in smoking cessation interventions for patients: a scoping review

BackgroundSmoking is a significant global public health concern, presenting substantial risks to individuals' health. Smoking cessation is essential for improving patients' well-being, and nurses play a critical role in assisting patients to quit smoking. However, there is a lack of research on nurses' specialized roles in smoking cessation interventions for patients.ObjectiveTo define the specific responsibilities of nurses in facilitating smoking cessation among patients, and provide guidance for future nursing interventions in smoking cessation.MethodsThe scoping review process was conducted for Arksey and O’Malley’s framework. Based on the three-step search strategy of Joanna Briggs Institute (JBI), a comprehensive search was performed across ten databases including PubMed, CINAHL, Web of Science, Embase, Cochrane Library, OVID, PsycINFO, CNKI, Wan Fang Data Knowledge Service Platform, and VIP Database for Chinese Technical Periodicals, covering studies from the inception of the databases to February 2024. The inclusion and exclusion criteria were developed using the JBI (participants, content, and context) principle. Randomized controlled trials or quasi-experimental studies with nurse-led or involved smoking cessation interventions for patients were included. Data extraction was conducted independently by two reviewers. The findings were reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR).ResultsIn total, 53 studies were eligible for the final charting and synthesis. The analysis identified six key roles that nurses played in smoking cessation interventions: assessors, educators, practice facilitators, coordinating collaborators, organizers, and supervisors. Among these, the roles of assessors, educators, and practice facilitators were the most commonly reported. The motivation interview and 5A method were the predominant techniques employed for smoking cessation. Nurses primarily promoted smoking cessation through the distribution of pamphlets, face-to-face education, and the provision of smoking cessation guidance. The primary participants in these studies were patients with chronic obstructive pulmonary disease (COPD).ConclusionsNurses play an indispensable role in smoking cessation interventions, occupying multiple critical roles. However, this review identified a gap in the pre-intervention training of nurses, indicating a need for enhanced training programs to better prepare nurses for effective smoking cessation interventions.

Osmotic demyelination syndrome: revisiting the diagnostic criteria through two fatal cases

BackgroundOsmotic Demyelination Syndrome (ODS) encompasses Central Pontine Myelinolysis and Extrapontine Myelinolysis, both of which are serious neurological conditions linked to the overly rapid correction of hyponatremia. Despite growing evidence, the exact etiology of ODS remains incompletely understood. The present paper describes two case studies, aiming to provide a comprehensive overview of the pathological findings and clinical outcomes associated with ODS.Case presentationCase #1. A 74-year-old woman was admitted to the emergency department following a head trauma caused by a loss of consciousness. Initial laboratory tests revealed severe hyponatremia (sodium level of 101 mmol/L) and hypokalemia (potassium level of 2.9 mmol/L). The patient underwent corrective therapy with saline and potassium chloride. Despite the correction of electrolyte imbalances, the patient developed a hyperintense lesion in the median portion of the pons on T2-fluid-attenuated inversion recovery (FLAIR) MRI sequence 14 days post-treatment, consistent with ODS. The patient’s condition deteriorated, leading to irreversible coma and status epilepticus, culminating in death 32 days after admission. Case #2. An 81-year-old woman with a medical history of hypothyroidism, hypertension, major depression, and stage 3 chronic kidney disease presented with mild gait disturbances. Subsequent testing revealed severe hyponatremia (sodium level of 100 mmol/L). Following an initial clinical improvement due to sodium correction, the patient’s condition worsened, with symptoms progressing to confusion, lethargy, and eventually, ODS. Dermatological manifestations, including blistering lesions and facial edema, appeared as the condition advanced. The patient succumbed to irreversible coma 47 days after admission.ConclusionODS traditionally carried a poor prognosis, with high mortality rates and diagnoses often made postmortem. However, recent advances in understanding the pathophysiology, along with improvements in diagnostic techniques such as MRI and intensive care treatments, have led to earlier identification, treatment, and recognition of milder forms of the syndrome. Despite these advancements, ODS remains a critical condition with significant risks, particularly following the rapid correction of severe hyponatremia.

Diagnostic and prognostic value of plasma lipocalin-2 levels in patients with metabolic dysfunction–associated steatotic liver disease

Abstract Background Non-Alcoholic Fatty Liver Disease, recently better recognised as Metabolic Dysfunction–Associated Steatotic Liver Disease, is the most prevalent form of chronic liver disease at present time. It is estimated to impact 32% of the world's population, hence representing a significant health burden. Aim of the work To assess the significance of plasma Lipocalin-2 (LCN2) levels in the diagnosis and prognosis of NAFLD patients. Patients and methods In this retrospective case–control study we recruited 102 subjects aged between 18 and 70 years. The included participants were split into two study groups. Group I: 51 NAFLD patients (61% men, 39% females) and Group II: 51 healthy controls (51% men and 49% females), for whom plasma LCN2 levels were assessed and correlated with NAFLD fibrosis score, FIB4 and fatty liver index. Results In this study, LCN2 levels in NAFLD patients were significantly greater compared to individuals in the control group (p < 0.001), with a mean of 1893.214 ± 1002.852 ng/dL in the cases and a mean of 466.020 ± 397.699 ng/dL in the controls. This suggests the use of LCN2 as a possible diagnostic marker of NAFLD. The mean LCN2 levels in this study also significantly increased as the grade of fatty liver increased from I to III (p < 0.001). This in turn proposes the use of LCN2 as a prognostic marker for NAFLD progression. LCN2 also significantly correlated with the fatty liver index and NAFLD Fibrosis scoring systems, but not with Fib-4. With an area under the ROC of 0.906, it demonstrated excellent diagnostic performance with 84% sensitivity, 90% specificity, 89.6% PPV and 85.2% NPV for the prediction of NAFLD patients. Conclusion Lipocalin-2 performs as a diagnostic and a possible prognostic marker for metabolic dysfunction-associated steatotic liver disease.

Breastfeeding, genetic susceptibility, and the risk of asthma and allergic diseases in children and adolescents: a retrospective national population-based cohort study.

Asthma and allergic diseases (such as allergic rhinitis) are multifactorial chronic respiratory diseases, and have many common pathogenic mechanisms. This study aimed to assess the joint effects of breastfeeding and genetic susceptibility on asthma, allergic disease in children and adolescents and sought to examine whether the effect of breastfeeding was consistent under distinct levels of genetic risk. A total of 351,931 UK Biobank participants were analyzed. Firstly, Cox proportional hazards model was used to evaluate the relation between breastfeeding and asthma, allergic disease and their comorbidity. Next, we incorporated the polygenic risk score as an additional covariate into the model. Then, we explored the role of breastfeeding at each stage of asthma and allergic disease through a multi-state model. Meanwhile, several sensitivity analyses were conducted to evaluate the robustness of our results. Finally, we calculated the attributable protection and population attributable protection of breastfeeding. Breastfeeding was related to a reduced risk of occurring asthma (adjusted hazard ratio [HR] = 0.89, 95% confidence interval [CI] 0.86 ~ 0.93), allergic disease (HR = 0.89, 95%CI 0.87 ~ 0.91) and comorbidity (HR = 0.89, 95%CI 0.83 ~ 0.94). The effect of breastfeeding was almost unchanged after considering PRS and did not substantially differ across distinct genetic risk levels. Breastfeeding showed a stronger risk-decreased impact on individuals who developed from allergic rhinitis to comorbidity (HR = 0.83, 95%CI 0.73 ~ 0.93). Further, the influence of breastfeeding was robust against covariates considered and the confounding influence of adolescent smoking. Finally, due to breastfeeding, 12.0%, 13.0% or 13.0% of the exposed population would not suffer from asthma, allergic diseases and the comorbidity, while 7.1%, 7.6% or 7.6% of the general population would not suffer from these diseases. This study provided supportive evidence for the risk-reduced effect of breastfeeding on asthma, allergic diseases, and the comorbidity in children and adolescents, and further revealed that such an influence was consistent across distinct genetic risk levels.

Two distinct clinical progressions of P67phox-deficient CGD, both commencing with cervical lymphadenitis.

We present two rare cases of p67phox-deficient chronic granulomatous disease (CGD) caused by compound heterozygous mutations in the NCF2 gene. They developed cervical lymphadenitis as the initial manifestation of CGD but had distinct clinical progressions. Patient 1 presented with aspergillous meningitis, an extremely rare manifestation of neurological involvement in CGD, which has not been reported before. Patient 2 presented with non-infectious inflammatory lymphadenitis is also very rare and has not been reported previously. These cases emphasize the importance of considering p67phox-deficient CGD in children with late-onset invasive fungal infections and non-infectious inflammatory lesions. Additionally, we also reviewed previous reports of Chinese patients with P67phox-Deficient CGD. Our objective is to raise awareness about the clinical, diagnostic, and genetic characteristics of P67phox-deficient CGD in China, to reduce misdiagnosis and improve the management and prognosis of the disease.

Clinical profile, inhaler technique, and predictors of inhaler adherence among asthma and COPD patients who attended the outpatient emergency department for acute exacerbation.

Understanding the patients' clinical profile, barriers to optimal inhaler use, and adherence are crucial in achieving the treatment goal for asthma and chronic obstructive pulmonary disease (COPD). This study aimed to assess the inhaler technique and identify the predictors of inhaler adherence among asthma and COPD patients who presented to the Emergency Department (ED). This prospective cross-sectional study recruited patients who presented to the outpatient ED of a tertiary hospital for mild-to-moderate exacerbation from March 2022 to February 2023. Convenience sampling was used in this study. The inhaler techniques and adherence of all subjects were evaluated. Regression analysis was used to identify predictors of inhaler adherence. We recruited 120 subjects with a mean age of 47.8 ± 16.0 and were predominantly asthma patients (n = 85, 70.8%). Most were on regular follow-up (n = 72, 60.0%) and adhered to their inhaler(s) (n = 86, 71.7%). Less than half of the subjects use their inhaler(s) correctly (n = 45, 37.5%). Three predictors of inhaler adherence were identified: regular follow-up (aOR 2.072, p = 0.041), correct inhaler technique (aOR 3.071, p = 0.039), and ability to explain inhalers' mode of action (aOR 10.906, p = 0.031). The high rate of wrong inhaler techniques among asthma and COPD patients is worrisome. Identified predictors of inhaler adherence should be targeted when managing this group of patients. In addition to the exacerbation treatment in the ED, referrals to public primary health clinics for regular follow-ups, evaluation of inhaler techniques, and counseling to enhance patient knowledge are crucial.
