Due to the increased photosensitivity and skin fragility, PCT patients are more susceptible to infections. Individuals with end-stage renal disease (ESRD), a potential complication of PCT, also exhibit an increased risk of infection. Due to these combined risks, this retrospective cohort study sought to determine if PCT is an independent risk factor for certain infections in the ESRD population.Methods: This study examined dialysis recipients within the United States Renal Data System database from 2005 to 2019. A diagnosis of PCT was determined using International Classification of Disease (ICD)-9 and ICD-10 codes and identified 1,019 (0.07 %) out of a total of 1,398,765 ESRD patients who met the inclusion and exclusion criteria. Bacterial infections, cellulitis, blisters, abscesses, and bacteremia were queried as outcomes. Logistic regression analysis determined the impact of PCT on the risk of each infection after controlling for demographic and clinical factors.Results: PCT was associated with a significantly decreased risk for 3 out of the 5 outcomes: bacterial infections (adjusted odds ratio: 0.50; 95 % confidence interval: 0.43-0.58), cellulitis (0.61; 0.53-0.71), and bacteremia (0.44; 0.38-0.52). No significant positive or negative association was found between PCT and blisters or abscesses.Conclusions: These results indicate that ESRD patients with PCT are actually at decreased risk of some infections compared with ESRD patients without comorbid disease. The reason is unclear but could be related to either the disease process or its clinical management.","PeriodicalId":94223,"journal":{"name":"The American journal of the medical sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the relationship between the triglyceride glycemic index (TyG) and the risk of invasive ventilator use in critically ill patients admitted to the intensive care unit (ICU).Methods: The study utilized the Medical Information Mart for Intensive Care-IV database. All patients were divided into three groups according to the TyG index. The study employed univariable and multivariable logistic regression analysis, competing risk analysis, and 4-knot multivariate restricted cubic spline regression. ROC curves were used to determine if the TyG index improves the predictive value of disease scores.Results: Out of 2196 participants, 51.9 % had invasive ventilation. Multivariable logistic regression analyses and competing risk analyses revealed that the risk of Invasive ventilator use was significantly higher in the highest quartile of the TyG index. Meanwhile, the RCS analysis indicated S-typed relationships between the TyG index and invasive ventilator use, with inflection points at 9.40, respectively. The TyG index had an incremental effect on the AUC of existing severity of illness scores to predict invasive ventilation.Conclusion: This study shows that an increased TyG index is a significant risk factor for invasive ventilation in patients in the ICU.","PeriodicalId":94223,"journal":{"name":"The American journal of the medical sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether octreotide reduces the burden of angiodysplasia or the frequency of bleeding in these patients is controversial. Hence, we aimed to study the effect of long-acting octreotide on angiodysplasia bleeding in LVAD patients.Methods: Between May 2012 and December 2023, 65 patients with LVAD and angiodysplasia were identified at our tertiary care medical center. Of those, 33 patients received octreotide therapy. Complete clinical data were abstracted from the medical record, and outcomes pre and post octreotide therapy were examined.Results: In 33 patients (61 ± 8 years old and 9 women) who received long-acting octreotide for recurrent angiodysplasia bleeding that failed to respond to endoscopic therapy, the small intestine was the most common site involved. Prior to octreotide, patients received an average of 2.0 ± 3.0 units/month of PRBCs over an average of 16 months, which decreased to 0.5 ± 0.8 units/month over 31 months on therapy. Over an average period of 31 months on octreotide therapy, GI bleeding events and the number of endoscopic therapies per month decreased from 0.4 ± 0.2 to 0.1 ± 0.2 (p = 0.01) and from 0.7 ± 0.8 to 0.1 ± 0.2 (p = 0.001), respectively. Finally, hemoglobin and hematocrit levels increased over the 31 month follow-up period while on octreotide therapy.Conclusion: In patients with an LVAD and recurrent angiodysplasia bleeding, octreotide appeared to reduce the number of GI bleeding events, the need for GI endoscopic therapies, and the frequency of PRBC transfusions.","PeriodicalId":94223,"journal":{"name":"The American journal of the medical sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Pearson's correlation tested LC rates and state health system performance.Results: A spatiotemporal trend map described discrete patterns. In 2023, Long COVID rates were highest in Southeastern states such as Mississippi and West Virginia, but by 2024, mixed patterns were observed in some states. The LC rates showed an inverse relationship with state health outcome scores (r = -0.69, P < 0.001). Emerging hotspot analysis identified Mississippi as a persistent hotspot for Long COVID.

Our study sought to investigate the relationship between protein-energy malnutrition and asthma exacerbation.Methods: We retrospectively searched the National Inpatient Sample (NIS) from 2018 to 2021. We searched the NIS for adult patients hospitalized with asthma exacerbation (AE) as the principal diagnosis and protein energy malnutrition (PEM) as a secondary diagnosis using ICD-10 codes. The primary outcome measures were inpatient mortality, while the secondary outcomes were length of stay (LOS), odds of respiratory failure (RF), cardiac arrest, pneumothorax, need for invasive mechanical ventilation, need for ECMO and health cost utilization, defined by total hospitalization costs. Multivariate logistic and Poisson regression analyses were applied to estimate the correlations.Results: A total of 325,510 patients were admitted for AE, 2,965 (0.91 %) of whom had underlying PEM. The PEM cohort had increased odds of mortality (aOR 3.70, p < 0.001). Similarly, the PEM cohort had increased odds of cardiac arrest (aOR 2.45, p = 0.008), pneumothorax (aOR 4.94, p < 0.001), acute respiratory failure (aOR 2.07, p = 0.001), and need for invasive mechanical ventilation (aOR 3.52, p < 0.001).

An attractive solution is the use of machine-learning algorithms to screen for radiographic features suggestive of pulmonary fibrosis. Thus, we developed and validated a machine learning classifier algorithm (ScreenDx) to screen computed tomography imaging and identify incidental cases of pulmonary fibrosis.Methods: ScreenDx is a deep learning convolutional neural network that was developed from a multi-source dataset (cohort A) of 3,658 cases of normal and abnormal CT's, including CT's from patients with COPD, emphysema, and community-acquired pneumonia. Cohort B, a US-based cohort (n = 381) was used for tuning the algorithm, and external validation was performed on cohort C (n = 683), a separate international dataset.Results: At the optimal threshold, the sensitivity and specificity for detection of pulmonary fibrosis in cohort B was 0.91 (95 % CI 88-94 %) and 0.95 (95 % CI 93-97 %), respectively, with AUC 0.98. In the external validation dataset (cohort C), the sensitivity and specificity were 1.0 (95 % 99.9-100.0) and 0.98 (95 % CI 97.9-99.6), respectively, with AUC 0.997. There were no significant differences in the ability of ScreenDx to identify pulmonary fibrosis based on CT manufacturer (Phillips, Toshiba, GE Healthcare, or Siemens) or slice thickness (2 mm vs 2-4 mm vs 4 mm).Conclusion: Regardless of CT manufacturer or slice thickness, ScreenDx demonstrated high performance across two, multi-site datasets for identifying incidental cases of pulmonary fibrosis.
