Background: We explored whether the effectiveness of immune checkpoint inhibitors (ICIs) can be characterized by incorporating a composite of duration of response (DOR) to complement traditional Response Evaluation Criteria in Solid Tumors (RECIST) criteria for objective response rate (ORR) in an intent-to-treat (ITT) population. Furthermore, the correlation of this novel endpoint, characterized by the restricted mean time in response (RMTR), with overall survival (OS) will be examined.

Methods: We analyzed ORR alone or in combination with DOR (RMTR) in available phase I, II, and III trials evaluating nivolumab monotherapy or in combination with ipilimumab across solid tumor types.

Basilar artery occlusion is rare, accounting for approximately 1% of strokes. Symptoms range from paresthesia and oculomotor symptoms to locked-in syndrome. Intervention can lead to complete neurological recovery despite the severity of initial deficits.

Growing literature has documented the clinical utility of neuropsychological evaluations for predicting functional outcomes, including reduced healthcare service utilization, in a variety of clinical samples. The present study investigates the relationship between the integration of clinical neuropsychology services into an existing outpatient sickle cell clinic and frequency of emergency department (ED) visits and hospitalizations for pain crises. Participants included 144 adults diagnosed with sickle cell disease (SCD) who either underwent neuropsychological evaluation (NP+), including interview, neuropsychological testing, and feedback, or treatment as usual (NP-).

Article Synopsis
  • Regulatory qualification of biomarkers ensures reliability for drug development, aiding both sponsors and regulators in the process.
  • The Coalition Against Major Diseases presented data to the European Medicines Agency to qualify hippocampal volume as a useful biomarker for clinical trials involving mild cognitive impairment.
  • The review and analysis backed the proposed use, leading to the successful qualification of an imaging biomarker by the European Medicines Agency in 2011.

Article Synopsis
  • Researchers cloned three types of gonadotropin-releasing hormone (GnRH) receptors in sea lampreys and examined their RNA expression during larval, parasitic, and adult life stages.
  • The study used RT-PCR to analyze expression across various tissues and in situ hybridization for adult brain and pituitary tissues, revealing varying levels of receptor expression through different life stages.
  • Findings indicated that the expression of GnRH receptors differs between male and female lampreys and is most prominent in adults, highlighting potential regulatory differences in reproductive stages.

Patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes often have decreased performance status secondary to extensive tumor involvement. Here, we report the pooled analysis of efficacy and safety data from two similarly designed phase III studies to provide a more precise estimate of benefit of ixabepilone plus capecitabine in MBC patients with Karnofsky's performance status (KPS) 70-80. Across the studies, anthracycline/taxane-pretreated MBC patients were randomized to receive ixabepilone plus capecitabine or capecitabine alone.

Background: Anecdotal reports of poor patient compliance with hepatitis C disease management exist yet little data are available on the true rates of dropout.

Aims: To examine all referrals made to an urban tertiary care liver centre for hepatitis C virus (HCV) management, track subsequent progress and identify dropout trends.

Methods: A cross-sectional retrospective review was conducted to examine the HCV referrals received on 2000 through 2007.

Background: Because there are limited head-to-head data comparing antiretroviral combinations, physicians are tempted to rely on cross-trial comparisons to evaluate the relative efficacy of HIV drugs. However, a variety of factors can confound these comparisons, resulting in misleading or invalid conclusions.

Objectives: To compare and evaluate the use of: (i) versions 1.

Advances in the treatment of the respiratory complications of cystic fibrosis, including the availability of lung transplantation have led to a greater awareness of the manifestations of liver disease in up to 40% of patients with Cystic Fibrosis (CF). We report the case of an 18 year old female with CF who presented with advanced hepatocellular carcinoma and no prior clinical evidence of chronic liver disease. Hepatocellular carcinoma is usually the most severe manifestation of advanced cirrhosis although its development in non-cirrhotic cases of chronic liver disease has been reported.

Background/aims: To examine if serum fibrosis biomarkers could accurately identify the stage of liver disease amongst hepatitis C (HCV) and HIV co-infected patients.

Methods: One hundred and thirty seven HIV/HCV co-infected persons were randomly selected from the Johns Hopkins HIV Clinic cohort. Ninety five had complete testing for fibrosis markers in sera collected at the time of liver biopsy.

Protease inhibitor (PI) treatment can result in dyslipidemia in a significant proportion of patients. Atazanavir (ATV) is a once-daily PI that has not been associated with clinically relevant increases in total cholesterol (TC), fasting low-density lipoprotein cholesterol (LDL-C), or fasting triglyceride (TG) concentrations. The objectives of this paper were to evaluate lipid profiles in untreated patients, and investigate the frequency and severity of dyslipidemia in the same individuals after treatment with ATV or nelfinavir (NFV) for 48 weeks.

Background/aims: Homozygosity for a cysteine to tyrosine translocation at position 282 within the HFE gene (C282Y) is responsible for over 90% of hereditary hemochromatosis (HH) in Celtic populations. Determining those C282Y homozygotes at greatest risk for iron overload is a major clinical concern as only a small percentage will develop clinically significant iron overload. Divalent metal transport protein (DMT1) on the apical surface of duodenal enterocytes is recognised as the major iron import protein.

The purpose of the study was to determine long-term efficacy, safety, and tolerability of atazanavir plus stavudine/lamivudine in 346 HIV-infected patients previously treated with atazanavir or nelfinavir. BMS AI424-044 is an ongoing, multicenter, international, open-label, rollover/switch study initiated in June 2001. Patients completing >or=48 weeks in trial BMS AI424-008 with a plasma HIV RNA viral load <10,000 copies/mL were eligible to continue on atazanavir (400 or 600 mg) or to switch from nelfinavir to atazanavir (400 mg) once daily.

Objective: To compare the efficiency and safety of atazanavir and nelfinavir in antiretroviral-naive patients.

Design: Randomization to atazanavir 400 mg or 600 mg once daily; nelfinavir 1250 mg twice a day, plus lamivudine and stavudine.

Methods: A blinded (to the atazanavir dose), 48-week trial in patients with HIV-1 RNA > or = 2000 copies/ml, CD4 cell count > or = 100 x 10(6) cells/l.
