Combatting negative bias: a mental contrasting and implementation intentions online intervention to increase help-seeking among individuals with elevated depressive symptomatology.

Background: There are many reasons why individuals with depression may not seek help. Among those with elevated depressive symptomatology, some previous interventions aimed at increasing help-seeking have unintentionally decreased help-seeking intentions. Beck's cognitive theory of depression posits that individuals with elevated depressive symptomatology process information differently from those without depression (i.

Impact of formulation on the iontophoretic delivery of the FOLFIRINOX regimen for the treatment of pancreatic cancer.

Purpose: Effective treatment of patients with locally advanced pancreatic cancer is a significant unmet clinical need. One major hurdle that exists is inadequate drug delivery due to the desmoplastic stroma and poor vascularization that is characteristic of pancreatic cancer. The local iontophoretic delivery of chemotherapies provides a novel way of improving treatment.

Docetaxel-Loaded PLGA Nanoparticles Improve Efficacy in Taxane-Resistant Triple-Negative Breast Cancer.

Novel treatment strategies, including nanomedicine, are needed for improving management of triple-negative breast cancer. Patients with triple-negative breast cancer, when considered as a group, have a worse outcome after chemotherapy than patients with breast cancers of other subtypes, a finding that reflects the intrinsically adverse prognosis associated with the disease. The aim of this study was to improve the efficacy of docetaxel by incorporation into a novel nanoparticle platform for the treatment of taxane-resistant triple-negative breast cancer.

Depression, help-seeking perceptions, and perceived family functioning among Spanish-Dominant Hispanics and Non-Hispanic Whites.

Introduction: Guided by Beck's (1967) cognitive theory of depression, we assessed whether perceived family functioning (PFF) mediated the relationship between depressive symptomatology and help-seeking inclinations.

Methods: Study 1 included 130 Spanish-Dominant Hispanics and Study 2 included 124 Non-Hispanic Whites obtained using online crowd sourcing. Participants completed measures of depressive symptomatology, PFF, and several scales measuring aspects of help seeking inclinations and self-stigma.

Design, Synthesis, and Characterization of Folate-Targeted Platinum-Loaded Theranostic Nanoemulsions for Therapy and Imaging of Ovarian Cancer.

Platinum (Pt) based chemotherapy is widely used to treat many types of cancer. Pt therapy faces challenges such as dose limiting toxicities, cumulative side effects, and multidrug resistance. Nanoemulsions (NEs) have tremendous potential in overcoming these challenges as they can be designed to improve circulation time, limit non-disease tissue uptake, and enhance tumor uptake by surface modification.

Iontophoretic device delivery for the localized treatment of pancreatic ductal adenocarcinoma.

Poor delivery and systemic toxicity of many cytotoxic agents, such as the recent promising combination chemotherapy regimen of folinic acid (leucovorin), fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX), restrict their full utility in the treatment of pancreatic cancer. Local delivery of chemotherapies has become possible using iontophoretic devices that are implanted directly onto pancreatic tumors. We have fabricated implantable iontophoretic devices and tested the local iontophoretic delivery of FOLFIRINOX for the treatment of pancreatic cancer in an orthotopic patient-derived xenograft model.

Tumor Presence Induces Global Immune Changes and Enhances Nanoparticle Clearance.

Long-circulating nanoparticles are essential for increasing tumor accumulation to provide therapeutic efficacy. While it is known that tumor presence can alter the immune system, very few studies have explored this impact on nanoparticle circulation. In this report, we demonstrate how the presence of a tumor can change the local and global immune system, which dramatically increases particle clearance.

Phase I study of intravenous (IV) docetaxel and intraperitoneal (IP) oxaliplatin in recurrent ovarian and fallopian tube cancer.

Objective: The primary objective was to define the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of IV docetaxel and IP oxaliplatin in women with recurrent ovarian (OV), fallopian tube (FT) or peritoneal (PP) cancer. Secondary objectives included response rate, time to progression, pharmacokinetics (PK) and quality of life (QoL).

Methods: Patients received docetaxel 75mg/m(2) IV day (d) 1 and oxaliplatin escalating from 50mg/m(2) IP d2 every 3weeks using a 3+3 design.

Evaluation of drug loading, pharmacokinetic behavior, and toxicity of a cisplatin-containing hydrogel nanoparticle.

Cisplatin is a cytotoxic drug used as a first-line therapy for a wide variety of cancers. However, significant renal and neurological toxicities limit its clinical use. It has been documented that drug toxicities can be mitigated through nanoparticle formulation, while simultaneously increasing tumor accumulation through the enhanced permeation and retention effect.

EGFR Targeted Theranostic Nanoemulsion for Image-Guided Ovarian Cancer Therapy.

Purpose: Platinum-based therapies are the first line treatments for most types of cancer including ovarian cancer. However, their use is associated with dose-limiting toxicities and resistance. We report initial translational studies of a theranostic nanoemulsion loaded with a cisplatin derivative, myrisplatin and pro-apoptotic agent, C6-ceramide.

Local iontophoretic administration of cytotoxic therapies to solid tumors.

Parenteral and oral routes have been the traditional methods of administering cytotoxic agents to cancer patients. Unfortunately, the maximum potential effect of these cytotoxic agents has been limited because of systemic toxicity and poor tumor perfusion. In an attempt to improve the efficacy of cytotoxic agents while mitigating their side effects, we have developed modalities for the localized iontophoretic delivery of cytotoxic agents.

Effects of a one-hour intervention on condom implementation intentions among drug users in Southern California.

Approximately 36% of HIV cases are related to substance abuse. Substance abusers, including non-injection drug users, are at a high-risk for contracting HIV due to risky behaviors, including unprotected sex. Due to these behavioral and infection risks, feasible interventions that focus on condom use within this population are imperative.

Depression and help seeking among Mexican-Americans: the mediating role of familism.

Increased depression symptomatology results in a reduced willingness to seek help from family. Focusing on Mexican-Americans, the current study hypothesized that the a reduction in favorable perceptions of familial relations could be partially to blame for limited help seeking among people with depression. Data were collected from 84 Mexican-Americans.
