Objectives: This pilot study aimed to prospectively investigate the effects of a wearable monitoring device, based on an Internet management platform, on the comprehensive management of type 2 diabetes mellitus (T2DM) patients.

Methods: A total of 120 hospitalized patients with T2DM were enrolled and randomly divided into the control group and the intervention group. Patients in the control group only received conventional diabetes treatments, while patients in the intervention group were provided with a wearable monitoring device in addition to conventional diabetes treatments. Moreover, the wearable device could connect to an Internet platform for diabetes management and upload self-monitoring data. All patients were followed for 3 months. The changes in parameters representing glucose metabolism, blood lipids, renal function, and patient satisfaction were compared between the two groups. All results were analyzed on an intention-to-treat basis.

Results: One hundred twenty subjects met all criteria and agreed to participate in this study. During the follow-up period, 5 and 4 subjects were lost to follow-up in the intervention and control groups, respectively. Compared with the control group, the blood glucose of the intervention group decreased significantly after 3 months (p < 0.05). Subgroup analysis found that females, those younger than 60 years, with baseline glycated hemoglobin A1c (HbA1c) levels of 8% or greater, and patients with good adherence showed significant improvements in HbA1c (p < 0.05). However, there was no significant difference in blood lipid and renal function. The intervention group showed a better adherence rate to blood glucose, comprehensive adherence rate, and diabetes treatment satisfaction (p < 0.05). One subject in the intervention group and two subjects in the control group reported mild hypoglycemia. No other adverse events such as infections and skin allergies occurred in the two groups.

Conclusion: The intervention of a wearable monitoring device based on an Internet management platform significantly improved blood glucose control in T2DM patients, as well as the overall adherence rate and patient satisfaction with treatment.

With more than 30 available stimulant medications, choosing among therapeutic options for attention-deficit/hyperactivity disorder (ADHD) has become increasingly complex and patient specific. All ADHD stimulants owe their action to variants of either amphetamine or methylphenidate, yet formulation and delivery system differences create unique pharmacokinetic and clinical profiles for each medication. A benefit of the diversity within ADHD pharmacotherapy is that it facilitates tailoring treatment to meet patient needs. Historically, there has been a constant among long-acting stimulant options, regardless of formulation, which was morning dosing. The introduction of delayed-release and extended-release methylphenidate (DR/ER-MPH) is the first long-acting stimulant that patients take in the evening, with the clinical effect delayed until awakening in the morning. This paradigm shift has generated questions among clinicians and continued interest in real-world experience and data. This review used available clinical data, real-world evidence, emerging analyses, and clinical experience to evaluate the characteristics of DR/ER-MPH and its clinical utility within the greater context of ADHD medications and to provide clinicians with practical guidance on the use of DR/ER-MPH in children, adolescents, and adults with ADHD.

Objectives: Atopic dermatitis (AD) is a chronic inflammatory skin disease often associated with non-atopic comorbidities. Recently, a severity-dependent relationship between AD and sleep/mental health diseases has been proposed. However, few studies investigated these comorbidities and their association with AD severity through validated questionnaires. This study aimed to use a set of validated instruments to assess the impact of AD on sleep and psychological disorders and estimate the association of itch and AD severity with sleep disorders and psychological symptoms, distinguishing between clinical-oriented and patient-oriented measures.

Methods: We conducted a case-control study, recruiting 57 adult AD patients (mean age ± std. dev. 34.28 years ± 13.07; 27 males) matched for age and sex with 57 healthy adults (34.39 years ± 13.09; 27 males). To investigate the differences in sleep quality, insomnia, depression, and anxiety between the two groups, we performed independent sample t-Tests. Moreover, we conducted univariate linear regression analyses to examine the relationship between itch and objective/subjective severity of AD and sleep quality, insomnia, and psychological symptoms.

Results: AD patients reported lower sleep quality (p = 0.002), more severe insomnia (p = 0.006) and depression (p = 0.013), and higher stress levels than healthy adults (p = 0.049). Itch intensity was linked to sleep disturbances and psychological symptoms (R²_range = 0.13-0.19, p_range = 0.02-<0.001). Objective and subjective AD severity were similarly associated with worse sleep quality (R² = 0.26, p < 0.001; R² = 0.24, p < 0.001; respectively), anxiety (R² = 0.15, p = 0.04; R² = 0.17, p = 0.001; respectively), and self-perceived stress (R² = 0.10, p = 0.02; R² = 0.07, p = 0.049; respectively). However, subjective AD severity was more strongly associated with insomnia (R² = 0.31, p < 0.001) and depression (R² = 0.20, p < 0.001) than clinical-oriented AD severity (R² = 0.19, p < 0.001; R² = 0.05, p = 0.098; respectively).

Conclusions: The study demonstrated poor sleep quality and high levels of insomnia, depression, and stress in AD patients, with an aggravated psychological status for adults with more severe skin disease. We suggest implementing a multidisciplinary approach to AD management/treatment that considers objective and subjective measures of disease severity.

Objectives: To investigate the association between lipid ratios and survival outcomes in patients with locally advanced breast cancer (LABC) undergoing neoadjuvant chemotherapy.

Method: This retrospective study included patients with LABC receiving neoadjuvant chemotherapy. Serum lipid levels were prospectively measured at baseline. Associations of triglyceride to total cholesterol (TG/TC), triglyceride to high-density lipoprotein (TG/HDL) and triglyceride to low-density lipoprotein (TG/LDL) ratios with prognosis were evaluated.

Results: Patients with high TG/TC (adjusted hazard ratio [aHR] = 2.47, 95% CI: 1.10, 5.56, p = 0.029), TG/HDL (aHR = 2.73, 95% CI: 1.16, 6.41, p = 0.021) and TG/LDL (aHR = 2.50, 95% CI: 1.11, 5.65, p = 0.027) ratios were more likely to experience disease-free survival (DFS) events. Subgroup analysis suggested that the prognostic impact of lipid ratios was more pronounced in patients with negative HER2 status or those at a high risk of recurrence (e.g. clinical stage III, Ki67 > 30%). Additionally, higher lipid ratios tended to indicate early DFS events (0 ~ 2 years) (TG/TC p = 0.021, TG/HDL p = 0.046, TG/LDL p < 0.001), and the TG/LDL ratio demonstrated the best predictive efficacy (TG/TC vs. TG/HDL vs. TG/LDL, 1-year AUC: 0.724 vs. 0.676 vs. 0.846, 2-year AUC: 0.653 vs. 0.638 vs. 0.708).

Conclusion: Baseline serum TG/TC, TG/HDL and TG/LDL ratios were independent prognostic factors in patients with LABC undergoing neoadjuvant therapy. However, their utility in predicting the early DFS events warrants further investigation.

Background: This study aimed to investigate the association between sex hormones and the risk of pulmonary fibrosis by conducting a meta-analysis of previously published studies.

Methods: We executed a comprehensive search of the PubMed, Embase, Cochrane Library, and Web of Science databases to locate pertinent studies published up to April 2024. We included studies that reported the association between sex hormones and the risk of pulmonary fibrosis. Standardized mean difference (SMD) with 95% confidence intervals (CIs) were calculated using a random-effects model.

Results: A total of 10 articles, encompassing 1371 patients, were finally incorporated in this meta-analysis. Based on the evaluation of the included studies, it was observed that the levels of dehydroepiandrosterone sulfate (DHEA-S) (pooled SMD: -0.72, 95% CI: -1.21 to -0.24, p < 0.001), testosterone (pooled SMD: -1.25, CI: -2.39 and -0.11, p < 0.001) and estrogen (pooled SMD: -0.56, 95% CI: -0.96 to -0.15, p < 0.001) were significantly lower in patients with pulmonary fibrosis, whereas the levels of luteinizing hormone (LH) remained unaffected. Publication bias was ruled out through funnel plots.

Conclusion: This meta-analysis indicates that reduced levels of DHEA-S, testosterone, estrogen may serve as potential risk factors for pulmonary fibrosis. There is a pressing need for additional studies to confirm this association and explore the underlying biological mechanisms. Clinicians should recognize the potential influence of sex hormones in the etiology of pulmonary fibrosis and consider this aspect during the patient management process.

Purpose: Although thrombolysis obliterans (TAO) has been recognized for more than a century, there is no optimal treatment for this disease. The aim of this report was to compare the short-term efficacies of catheter-directed thrombolysis (CDT), percutaneous transluminal angioplasty (PTA) and CDT+PTA in treating TAO disease.

Method: Consecutive patients with TAO treated at Ganzhou People's Hospital between 2012 and 2022 were included in this retrospective study. According to the information provided in the medical records, endovascular procedures included CDT, PTA or CDT+PTA. One-year follow-up outcomes of the patients with TAO who underwent endovascular procedures were compared. The primary outcome was major adverse limb event (MALE) and the secondary outcomes were the technical success, complications, ABI at 1 week after surgery and minor amputation.

Results: Sixty-nine patients with TAO were assessed for inclusion in our single-center study from 2012 to 2022 and received endovascular procedures. Among them, 22 patients underwent CDT, 21 patients underwent PTA, and 26 patients underwent PTA+CDT. The one-year follow-up revealed significant differences in the MALE-free survival rates among the three groups, particularly between the CDT group and the PTA+CDT group (the hazard ratio (HR) for MALE-free survival was 0.173, 95% CI [0.050-0.599], p = 0.006). The technical success rates of the three groups were 63.6%, 90.5%, and 92.3%, respectively. There were differences in the ABI at one week after surgery among the three groups.

Conclusions: Endovascular procedures are effective for TAO in the short term. The effectiveness of CDT alone is suboptimal; combining CDT with PTA achieves the most favorable endovascular treatment outcome; while the effectiveness of PTA falls in between these two procedures.

Hiatal hernia (HH) is a common disease in the general population. It is often asymptomatic, but if it does present clinical manifestations, these are usually gastrointestinal. Gastroesophageal reflux is the main symptom that accompanies it. Depending on the severity of the hernia, it is classified into several subtypes from I-IV. Especially, IV type (giant HH) can lead to various cardiopulmonary symptoms with several degrees of severity. It is necessary to keep this possibility in mind among the various differential diagnoses that may occur in this clinical setting. The current paper aims to review the literature on classic and novel information on the HH - cardiovascular system relationship. Epidemiological data, physiological aspects of the heart compressed by HH, cardiovascular symptoms, electrocardiographic changes, echocardiographic alterations and clinical implications are discussed.

Objectives: This study sought to investigate the relationship between the systemic inflammatory response index (SIRI) and bone mineral density (BMD), osteoporosis, and future fracture risk in elderly hypertensive patients.

Methods: Elderly hypertensive patients (age ≥60 years) who attended our hospital between January 2021 and December 2023 and completed BMD screening were included in the study. Analyses were performed with multivariate logistic and linear regression.

Results: The multiple linear regression indicated that SIRI levels were significantly negatively correlated with lumbar 1 BMD (β = -0.15, 95% CI: -0.24, -0.05), lumbar 2 BMD (β = -0.15, 95% CI: -0.24, -0.05), lumbar 3 BMD (β = -1.35, 95% CI: -0.23, -0.02), lumbar 4 BMD (β = -0.11, 95% CI: -0.30, -0.10), femur neck BMD (β = -0.11, 95% CI: -0.18, -0.05) and Ward's triangle BMD (β = -0.12, 95% CI: -0.20, -0.05) among elderly hypertensive patients, after fully adjusting for confounders. Furthermore, we observed that SIRI was positively associated with future fracture risk in elderly hypertensive patients. Specifically, SIRI was associated with an increased risk of major osteoporotic fractures (β = 0.33) and hip fractures (β = 0.25). The logistic regression analysis indicated that there is an association between the SIRI level and an increased risk of osteoporosis (OR = 1.60, 95% CI = 1.37, 1.87), after fully adjusting for confounders.

Conclusions: Our findings indicate a potential association between SIRI and BMD, osteoporosis, and the risk of future fractures in elderly hypertensive patients. However, further studies are warranted to confirm these findings.

Objectives: Over-testing and over-treatment are common in children with croup at pediatric emergency departments (PED). The objective of the study was to improve care for children with croup.

Methods: In this quality improvement (QI) initiative, all pediatric residents starting their rotation in the PED attended an informative presentation about croup and were provided reminders throughout their rotation. The primary outcome of this QI initiative was to reduce nebulized epinephrine (NE) use among children with mild croup by 50% over 7 months. The secondary outcome was to reduce X-rays by 50% over 7 months. Other outcomes included the administration of dexamethasone to all children with croup, reduction of antibiotics, laboratory tests, and revisits, and shortening the duration between physical examination to dexamethasone and NE treatments, and the length of stay (LOS) at the PED.

Results: NE administration to patients with mild croup decreased from 80.2% to 36.3% (p < 0.001). The proportion of children with X-rays decreased from 37.4% to 17.1% (p < 0.001). There was a significant increase in dexamethasone administration, and significant decreases in laboratory blood tests, expanded viral PCR panel tests, and antibiotic prescription among all croup cases (p < 0.001). Revisit rates were not significantly different (p > 0.05). Time to dexamethasone and LOS shortened significantly (p < 0.001).

Conclusion: With this QI intervention, decreases in the rate of administration of NE to mild croup cases, antibiotic prescription, X-ray, laboratory blood and respiratory PCR panel tests in all croup cases were achieved without an increase in revisits. However, unnecessary NE, antibiotic, and X-ray rates are still high.
