Nontuberculous mycobacterial (NTM) pulmonary infections in people with cystic fibrosis (CF) are associated with significant morbidity and mortality and are increasing in prevalence. Host risk factors for NTM infection in CF are largely unknown. We hypothesize that the airway microbiota represents a host risk factor for NTM infection. In this study, 69 sputum samples were collected from 59 people with CF; 42 samples from 32 subjects with NTM infection (14 samples collected before incident NTM infection and 28 samples collected following incident NTM infection) were compared to 27 samples from 27 subjects without NTM infection. Sputum samples were analyzed with 16S rRNA gene sequencing and metabolomics. A supervised classification and correlation analysis framework (sparse partial least-squares discriminant analysis [sPLS-DA]) was used to identify correlations between the microbial and metabolomic profiles of the NTM cases compared to the NTM-negative controls. Several metabolites significantly differed in the microbiome and metabolome data from CF sputum samples. The data obtained in this study identified several metabolic profile differences in sputum associated with NTM infection in CF, including 2-methylcitrate/homocitrate and selected ceramides. These findings represent potential risk factors and therapeutic targets for preventing and/or treating NTM infections in people with CF.The International Liver Association recommends the use of accurate and sensitive molecular methods for determination of hepatitis B virus (HBV) DNA levels in plasma or serum of chronic HBsAg carriers. The level of HBV replication represents the strongest predictive biomarker associated with disease progression and long-term outcome of chronic HBV infection. The purpose of this study was to evaluate the ability to the new Alinity m System to detect and quantify HBV DNA in plasma and whole blood collected on dried blood spots (DBS). Paired plasma and DBS samples from patients chronically infected with various HBV genotypes were tested in parallel for HBV DNA detection and quantification. There is a linear relationship between HBV DNA levels measured in plasma samples using the Alinity m HBV assay and the Xpert HBV viral load assay, used for comparison. A slight deviation (0.03 ± 0.31 log IU/mL) was observed within the quantitative range. In DBS, HBV DNA levels closely correlated with levels measured in plasma. levant cutoffs of 2,000 and 20,000 IU/mL. read more Results support the use of DBS in community-based settings.
We present a novel digital workflow to provide presurgical infant orthopedic (PSIO) treatment for a patient with a unilateral cleft lip/palate utilizing nasoalveolar molding (NAM) and a custom postsurgical nasal stent.

Within the US military healthcare system, the Joint Base San Antonio Craniofacial Anomalies Team utilizes dental scanners, predictive 3D modeling software, and 3D printing technology in a digital workflow for NAM appliance fabrication.

Soft tissue facial scanning, peri-oral scanning, and dental putty impressions are used to facilitate fabrication and measure outcomes. Digital modeling software and 3D resin printing are utilized to manufacture the prescribed devices.

Extra-oral facial scans and intra-oral impressions are compared between 3 timepoints pre-treatment, posttreatment with NAM, and postsurgical treatment.

The ability to share workflows, establish outcome standards, and streamline patient care will continue to advance best practices in digital PSIO.

Neuroendocrine carcinomas are very aggressive tumors with few treatment options. DLL3 seems to be an optimal target for therapeutic intervention, as it is expressed mainly on the membrane of tumor cells with neuroendocrine origin.

In this article, we outline the preclinical and clinical studies published in the last years on DLL3 in neuroendocrine neoplasm, above all of lung origin. Furthermore, we review the current literature on the interaction between DLL3 and the tumor microenvironment.

Several DLL3-targeting strategies have been proposed in the last years with mixed results. Understanding the influence of DLL3 on the tumor (immune) microenvironment and developing adoptive therapies directed against this optimal target might represent the key strategy. Building on the clinical data obtained so far, future trials on in vivo diagnostic tools for predictive purpose and new specific therapies are needed.

This study was undertaken to examine the postoperative outcomes, costs, and survival after robotic hepatectomy for hepatocellular carcinoma (HCC) in patients with or without metabolic syndrome.

Following IRB approval, we prospectively followed 56 patients undergoing robotic hepatectomy for HCC from 2016-2020. Patients with metabolic syndrome were compared to patients without metabolic syndrome regarding postoperative clinical outcomes, costs, and survival. Propensity score matching of a 11 ratio matched patients with and without metabolic syndrome according to 6 variables.

17 patients were matched to each arm. Mean age was 64 ± 14.0years and 30 patients (88%) had operations that were classified as advanced (IWATE 7-9) or expert (IWATE 10-12). There were no differences between patients with metabolic syndrome versus patients without metabolic syndrome in terms of operative duration (306 [301 ± 76.2] vs 239 [260 ± 116.9] minutes; P = 0.23), estimated blood loss (300 [321 ± 195.5] vs 200 [214 ± 151.4] ml; P = 0.08), conversion to "open" operation (1 [6%] vs 1 [6%]; p = 1.00), tumor size (5 [5 ± 3.0] vs 3 [4 ± 2.2] cm; P = 0.28), postoperative complications with Clavien-Dindo Score (≥III) (0 vs 1; P = 1.00), in-hospital mortality (0 [0%] vs 1 [6%]; P = 1.00), length of stay (5 [5 ± 1.7] vs 4 [5 ± 4.4] days; P = 1.00), and 30-day readmissions (1 [6%] vs 1 [6%]; P = 1.00). There were no differences in overall costs and profit. There was no difference in 1-year, 2-year, and 3- year overall survival in patients with or without metabolic syndrome after robotic HCC resection (84% vs 77%, 84% vs 61%, and 45% vs 61%, P = 0.42).

For patients with and without metabolic syndrome, robotic advanced/expert hepatectomy for HCC resulted in similar intra-operative metrics, postoperative outcomes, costs, and survival.

The treatment options and therapeutics available for these diseases are hindered by inadequate drug concentrations at pathological sites, a dearth of cell-specific targeting and different biological barriers in the alveoli or conducting airways. Nanostructured delivery systems for lung drug delivery have been significant in addressing these issues. The strategies used include surface engineering by altering the material structure or incorporation of specific ligands to reach prespecified targets. The unique characteristics of nanoparticles, such as controlled size and distribution, surface functional groups and therapeutic release triggering capabilities, are tailored to specific requirements to overcome the major therapeutic barriers in pulmonary diseases. In the present review, the authors intend to deliver significant up-to-date research in nanostructured therapies in inflammatory lung diseases with an emphasis on biocomposite-based nanoparticles.Mixed epithelial and stromal tumors of the kidney (MESTK) are rare and recently defined entities that comprise both epithelial and stromal cells. MESTK is mostly benign; however, to date, 18 borderline or malignant cases have been reported. In this study, we report a case of carcinosarcoma exhibiting a large carcinoma and small sarcoma component, and review the relevant literature. The patient was a 59-year-old woman who presented with a large mass in the left kidney having solid and focal cystic components. The patient underwent left radical nephrectomy. The tumor was gray-white and solid-cystic, with a relatively clear boundary. Microscopically, the tumor revealed benign and malignant components. The benign component consisted of multiple tubules, variable-sized cysts lined with benign epithelium, and hyalinized stroma. The malignant component was composed of predominantly small cell neuroendocrine carcinoma and a small quantity of adenocarcinoma, squamous cell carcinoma, and sarcoma. Finally, a diagnosis of the malignant MESTK was made. Certain cases of borderline or malignant transformation of MESTK have been published, so it is important to enhance findings made by other studies.Mexican Americans have a high prevalence of diabetes and burden of diabetes-related complications, highlighting the need for novel preventive strategies and noninvasive predictors of diabetes risk tailored to this population. Changes in the gut microbiome have the potential to predict diabetes. Here, we aimed to identify alterations in the gut microbiome associated with diabetes in the high-risk population of Mexican Americans in South Texas. Stool samples were collected from 216 subjects from the population-based Cameron County Hispanic Cohort. Among them, 75 had type 2 diabetes. Taxonomic and functional profiling of the stool samples were assessed by 16S and shotgun metagenomic sequencing, and the influence of genetic factors was explored. The gut microbiome of subjects with diabetes was enriched with proinflammatory Proteobacteria members (Enterobacteriaceae, Escherichia-Shigella) and depleted of butyrate-producing Clostridiales members (Faecalibacterium prausnitzii, Peptostreptococcaceae, and Clostridium as well as host genetic factors that may explain increased disease susceptibility in this ethnic group. Using samples from a population-based cohort of Mexican Americans with a high prevalence of obesity and diabetes, we confirmed findings from studies on other ethnicities that suggested promotion of a chronic proinflammatory environment, loss of butyrate production, and compromised intestinal barrier integrity. High abundance of proinflammatory Proteobacteria was associated with a polymorphism that was more frequent in this cohort and in individuals of Mexican ancestry than in Europeans. Validation of microbiome-based risk models for diabetes should be evaluated in prospective cohort studies.
Lung cancer is the leading cause of cancer death, with an estimated 1.8 million deaths contributing to this cancer in 2020. Despite advances in treatment options and various approaches being attempted, the survival rate remains low.

In this review, we aim to provide an overview of the efficacy of tumor-infiltrating lymphocyte (TIL) therapy for lung cancer based on existing clinical trials. We also discuss the current challenges and future landscape of this treatment modality.

Lung cancer can be a suitable candidate for TIL therapy due to its high mutational burden. Specifically, it has shown promising results for non-small cell lung cancer resistant to immune checkpoint inhibitors. Still, there are many restrictions associated with the
expansion and delivery of TILs, limiting their availability. For this reason, applying TIL for the treatment of lung cancer has not been extensively investigated yet and only a few clinical trials have shown favorable results of TIL therapy in patients with lung cancer.
