REVIEW
Yi Xiong, Bi-Yun Huang, Ji-Ye Yin
Drug therapy for non-small cell lung cancer consists mainly of platinum-based chemotherapy regimens. However, toxicity, drug resistance, and high risk of death have been seen in the clinic, which means there is a need for optimizing the use of medications. Platinum resistance could be mediated by a series of DNA repair pathways, and therefore, these pathways should be taken into account for optimizing drug using. The goal of pharmacogenomics is to elucidate genetic factors, such as DNA repair genes, which might underlie drug efficacy and effectiveness, and to improve therapeutic effects or guide personalized therapy as well...

The emergency department (ED) can be a critical intervention point for many patients with multifaceted needs. Social workers have long been part of interdisciplinary ED teams. This study aimed to contribute to the limited understanding of social worker-patient interactions and factors influencing social work services in this setting. This paper reports a qualitative content analysis of social work medical record notes (N = 1509) of services provided to trauma patients in an urban, public, level 1 trauma center and an in-depth analysis of semi-structured interviews with ED social workers (N = 10)...

OBJECTIVES: Medication adherence is a complex problem and can be evaluated using a variety of methods. There is no single or perfect strategy to assess adherence. The "best" measure depends on contextual factors. Our objective is to provide a practical, illustrative guide for selecting the most appropriate measure of medication adherence in common contexts. METHODS: We present three case studies - from the perspectives of an academic researcher, health care payer, and clinical care provider - to describe common problems and processes for measuring medication adherence, as well as proposing possible solutions...

PURPOSE: During medical needle placement using image-guided navigation systems, the clinician must concentrate on a screen. To reduce the clinician's visual reliance on the screen, this work proposes an auditory feedback method as a stand-alone method or to support visual feedback for placing the navigated medical instrument, in this case a needle. METHODS: An auditory synthesis model using pitch comparison and stereo panning parameter mapping was developed to augment or replace visual feedback for navigated needle placement...

BACKGROUND: Despite emerging drug resistance in Cambodia, artemisinin-based combination therapy (ACT) is still the most efficacious therapy. ACT is available free of charge in the Cambodian public sector and at a subsidized rate in the private sector. However, un- and mistreated cases in combination with population movements may lead to the further spread of resistant parasites, stressing the importance of understanding how the perceived aetiology of malaria and associated health-seeking behaviour may delay access to appropriate treatment...

In cities throughout the United States, hundreds of thousands of sexual assault kits (SAKs) have not been submitted by the police for forensic DNA testing. Given recent media attention and public outcry about this problem, many jurisdictions with large numbers of untested SAKs are deciding to test all previously unsubmitted SAKs, which raises complex issues regarding when and how victims ought to be notified about what has happened to the kits that were collected during their medical forensic examinations. In this project, we collaborated with one community that has had large numbers of untested SAKs-Detroit, Michigan-to develop an empirically supported planning framework for how to create a victim notification protocol...

PURPOSE: Informal caregivers of individuals with cancer may experience substantial burdens. To develop interventions to support these caregivers, it is crucial to quantify and understand the domains of burdens potentially experienced by caregivers and factors contributing to each domain. METHODS: Using data from two national surveys, the National Survey of Caregiving (NSOC) linked to the National Health and Aging Trends Survey (NHATS), we identified all participants in the NHATS diagnosed with cancer who had a caregiver participating in the NSOC...

Deep abdominal vein thrombosis is extremely rare among thrombotic events secondary to the use of contraceptives. A case to illustrate the clinical utility of ethno-specific pharmacogenetic testing in warfarin management of a Hispanic patient is reported. A 37-year-old Hispanic Puerto Rican, non-gravid female with past medical history of abnormal uterine bleeding on hormonal contraceptive therapy was evaluated for abdominal pain. Physical exam was remarkable for unspecific diffuse abdominal tenderness, and general initial laboratory results-including coagulation parameters-were unremarkable...

COMMENT
Abhishek Chatterjee, John K Erban
The complexity of managing early stage breast cancer is well known. Optimal treatment is increasingly multidisciplinary and in the modern era informed by sophisticated molecular tools to help select and guide therapy. Major phase III trials have determined that the order of systemic therapy relative to surgery does not influence important endpoints such as event free survival and overall survival (OS), but questions remain as to how best to utilize these most essential services. For example, there is still uncertainty regarding the ideal timing, intensity, and duration of proposed therapy...

Neuroblastoma is the most common solid malignant neoplasm in the paediatric age group; accounting for 7% of all childhood malignancies, but neuroblastoma in adult, is a rare occurrence, finding mention in aeons of medical literature with an overall incidence of 1 in 10 million adults/year. We report the case of a 24-year-old male patient presenting with the complaints of progressive abdominal distention of 2 months duration. Multiple Detector Computed Tomography (MD-CT) of abdomen revealed a huge enhancing mass in the retroperitoneum abutting the left kidney, and a subsequent CT-guided biopsy and immunohistochemistry confirmed the diagnosis of ganglioneuroblastoma...

Ectodermal dysplasia (ED) is an inherited disorder characterized by abnormality of ectodermally derived structures. A recurrent oral finding is oligodontia, which in turn leads to a severely hypotrophic alveolar process with typical knife-edge morphology and adverse ridge contours. This unfavorable anatomy can seriously hamper proper implant placement. Fresh-frozen bone (FFB) allografts recently have been proposed to augment the residual bone volume for implant placement purposes; however, scientific evidence concerning the use of FFB to treat ED patients is absent...
