Historically, patients with stage IV non-small cell lung cancer (NSCLC) have been treated with chemotherapy alone, reserving local therapies for symptom palliation. However, evidence has accumulated that a subset of patients with oligometastatic NSCLC (OM-NSCLC) may benefit from local ablative therapies (LATs). In this article, we review the data that have formed the rationale for LAT, specifically radiotherapy, and the prospective trials that support its use in this population. Finally, we examine the evolving role of LAT in patients with OM-NSCLC in the context of immunotherapy and targeted therapies, as well as discuss ongoing clinical trials incorporating LAT in these patients.Medications used in the treatment of inflammatory bowel disease cause a wide range of dermatologic side effects, and minimal guidance exists on how to manage them. The intention of this review article is to summarize common dermatologic adverse reactions related to inflammatory bowel disease therapy and to provide evidence-based guidance on management. We conducted a scoping review using PubMed and Google Scholar to identify studies reporting clinical information on dermatologic side effects of medications used in the treatment of inflammatory bowel disease. The most commonly reported dermatological adverse effects from inflammatory bowel disease therapy were cutaneous malignancy and cutaneous infections. Thiopurines, methotrexate, tumor necrosis factor (TNF) inhibitors, interleukin (IL)-12/23 inhibitors, and integrin inhibitors can be continued if nonmelanoma skin cancer arises during therapy and the malignancy should be surgically excised. TNF inhibitors and IL-12/23 inhibitors can be continued in the setting of stage I surgically resectable melanoma but should be discontinued in advanced melanoma. For complicated cutaneous bacterial infections, methotrexate and TNF inhibitors should be halted, and IV antibiotics should be administered. Complicated herpes zoster infection warrants discontinuation of TNF inhibitors, whereas IL-12/23 and JAK inhibitors can be continued. Inflammatory bowel disease therapies are associated with several dermatological adverse effects, and management options vary by agent. Certain agents may require discontinuation in the setting of nonmelanoma skin cancer, melanoma, and cutaneous infections. Many other dermatological adverse effects from inflammatory bowel disease therapy require specialized management or referral to dermatology.Joint mean-covariance modeling of multivariate longitudinal data helps to understand the relative changes among multiple longitudinally measured and correlated outcomes. A key challenge in the analysis of multivariate longitudinal data is the complex covariance structure. This is due to the contemporaneous and cross-temporal associations between multiple longitudinal outcomes. Graphical and data-driven tools that can aid in visualizing the dependence patterns among multiple longitudinal outcomes are not readily available. In this work, we show the role of graphical techniques profile plots, and multivariate regressograms, in developing mean and covariance models for multivariate longitudinal data. We introduce an R package MLGM (Multivariate Longitudinal Graphical Models) to facilitate visualization and modeling mean and covariance patterns. Through two real studies, microarray data from the T-cell activation study and Mayo Clinic's primary biliary cirrhosis of the liver study, we show the key features of MLGM. We evaluate the finite sample performance of the proposed mean-covariance estimation approach through simulations.

Pathology and imaging tests are frequently requested in the outpatient setting despite historically poor completion rates. The impact of COVID-19 telehealth on test completion rates is unknown.

To examine the impact of the COVID-19 pandemic and telehealth transition on pathology and imaging test request and completion rates in Australian outpatient clinics.

We performed a prospective cohort study with historical controls between March-May 2019 and March-May 2020. Pathology and imaging request and completion rates were collected in review consultation patients attending Gastroenterology and Rheumatology outpatient clinics at a tertiary healthcare system prior and during the early phases of the COVID-19 pandemic in Melbourne.

1376 patients were included in the study. Pathology tests were requested more frequently in the COVID-19 group (n=582/684, 85.2%) than control group (n=492/692, 71.1%, p < 0.001) but completion rates were lower in the COVID-19 group (n=443/582, 76.1%) than control group (n=426/4iately mitigated.

The Mediterranean diet and other healthy dietary patterns can reduce liver fat and may be related with lower disease progression. The type of diet should be tailored to the patient's cultural and personal preferences. Changing dietary composition without reducing caloric intake may offer an additional and sometimes more feasible alternative, so that the nutritional treatment incorporates, but is not focused on, weight reduction goals. The growing global consumption of ultra-processed foods, which is the polar opposite of the Mediterranean diet and its concept of home-based cooking, poses a great challenge in the prevention of NAFLD and probably hepatocellular carcinoma.This review will cover the most updated clinical and epidemiological evidence for lifestyle treatment in NAFLD and provide practical treatment tools.Owing to species-specific differences in liver pathways, in vitro human liver models are utilized for elucidating mechanisms underlying disease pathogenesis, drug development, and regenerative medicine. To mitigate limitations with de-differentiated cultures, bioengineers have developed advanced techniques/platforms, including micropatterned cocultures, spheroids/organoids, bioprinting, and microfluidic devices, for perfusing cell cultures and liver slices. Such techniques improve mature functions and culture lifetime of primary and stem-cell human liver cells. Furthermore, bioengineered liver models display several features of liver diseases including infections with pathogens (e.g., malaria, hepatitis C/B viruses, Zika, dengue, yellow fever), alcoholic/nonalcoholic fatty liver disease, and cancer. Cyclopamine Here, we discuss features of bioengineered human liver models, their uses for modeling aforementioned diseases, and how such models are being augmented/adapted for fabricating implantable human liver tissues for clinical therapy.
