Introduction  RTOG 1205 is the only randomized study to evaluate the safety and efficacy of reirradiation (reRT) in recurrent glioblastoma (GBM). While this study showed that reRT was safe and improves progression-free survival (PFS), an improved approach to reRT is still needed. In this study, we report on patterns of failure and outcomes in a cohort of patients with recurrent GBM who underwent reRT.

Objectives: Based on a previous phase 1 study, total marrow irradiation (TMI) at 9Gy was added to a myeloablative FluBu4 conditioning regimen in allogeneic hematopoietic stem cell transplantation (HSCT) for myeloid malignancies. Here, we report on the long-term toxicity of TMI combined with FluBu4 and compare it to patients who received only FluBu4.

Methods: We retrospectively analyzed 38 consecutive patients conditioned with FluBu4/TMI (n = 15) or FluBu4 (n = 23, control group) who had at least 1 year follow-up post-transplant.

This review summarizes the clinical evidence supporting the utilization of stereotactic body radiotherapy (SBRT) for liver tumors, including hepatocellular carcinoma, liver metastases, and cholangiocarcinoma. Emerging prospective evidence has demonstrated the benefit and low rates of toxicity across a broad range of clinical contexts. We provide an introduction for the interventional radiologist, with a discussion of underlying themes such as tumor dose-response, mitigation of liver toxicity, and the technical considerations relevant to performing liver SBRT.

Article Synopsis
  • The Kaplan-Meier method can overestimate the risk of cancer coming back, especially when other events like death happen first, but the Aalen-Johansen method can give a more accurate picture by considering these events.
  • A study looked at research articles about meningiomas (a type of brain tumor) since 2020 and found that only a few used the better method.
  • It showed that not using the Aalen-Johansen method mostly led to overestimating the recurrence risk, especially in older patients with more serious tumors.

People with psychosis or bipolar disorder (severe and persistent mental illness [SPMI]) are at high risk for poor psychiatric and chronic illness outcomes, which could be ameliorated through improved health care quality. This study assessed whether a telehealth, collaborative care program managed by psychiatric clinical pharmacists (SPMI Population Care) was associated with improved health care quality for adults with SPMI in a large California health system. This retrospective cohort study used electronic health record data to compare 968 program enrollees at 6 demonstration sites (Population Care) to 8,339 contemporaneous patients with SPMI at 6 non-program sites (Usual Care).

Background: Postoperative pain affects 16%-25% of root canal therapy patients. The irrigating system and irrigants used should reduce bacterial load without irrigant extrusion beyond the root canal apex, potentially reducing postoperative pain and discomfort.

Aim: This study aims to compare the effects of passive ultrasonic irrigation and side-vented needle irrigation on postoperative pain and bacterial load in single-rooted teeth with pulp necrosis.

Background: Dengue fever is the second most common mosquito-borne disease affecting human beings and neurological manifestations (NMs) of this arboviral infection are increasingly being reported.

Methods: In this retrospective study, conducted in a tertiary care centre in south India, we sought to describe the spectrum of NMs of dengue fever. The records of all patients admitted in the Department of Internal Medicine over 8 years, with a diagnosis of dengue-based on clinical symptoms and the detection of dengue IgM antibodies or detection of NS1 antigen or nucleic acid by reverse transcriptase-polymerase chain reaction (RT-PCR); with Glasgow coma score (GCS) ≤14, neck stiffness, focal neurological signs, seizures, or visual disturbances-were explored.

Background Collaborative care is an evidence-based multidisciplinary model shown to improve patient depression and anxiety outcomes. Although there is robust literature showing the effectiveness of collaborative care on depression and anxiety symptoms, there is little published on outcomes of collaborative care implementation or the efficacy of collaborative care compared with psychiatric referrals. Reported here is a study protocol examining a novel depression and anxiety collaborative care program in a large, integrated health care system.

Introduction: We sought to determine if increased use of stereotactic body radiation therapy (SBRT) was associated with decreased disparities in the receipt of definitive treatment for early-stage non-small cell lung cancer (NSCLC).

Methods: The National Cancer Database (NCDB) was utilized to determine the proportion of patients with NSCLC receiving surgery, SBRT, or no definitive treatment for clinical cT1-2aN0M0 NSCLC from 2004-2017. Univariable and multivariable logistic regressions were used.

Purpose: Total marrow irradiation (TMI) involves optimization of extremely large target volumes and requires extensive clinical experience and time for both treatment planning and delivery. Although volumetric modulated arc therapy (VMAT) achieves substantial reduction in treatment delivery time, planning process still presents a challenge due to use of multiple isocenters and multiple overlapping arcs. We developed and evaluated a knowledge-based planning (KBP) model for VMAT-TMI to address these clinical challenges.

IL-6 is elevated in obese individuals and participates in the metabolic dysfunction associated with that condition. However, the mechanisms that promote IL-6 expression in obesity are incompletely understood. Because elevated levels of palmitate and LPS have been reported in obesity, we investigated whether these agents interact to potentiate IL-6 production.
