Nociceptor-localized cGMP-dependent protein kinase I is a critical generator for central sensitization and neuropathic pain.

Patients with neuropathic pain often experience exaggerated pain and anxiety. Central sensitization has been linked with the maintenance of neuropathic pain and may become an autonomous pain generator. Conversely, emerging evidence accumulated that central sensitization is initiated and maintained by ongoing nociceptive primary afferent inputs.

Presurgical depression and anxiety are not associated with worse epilepsy surgery outcome five years postoperatively.

Purpose: Anxiety and depression have been associated with poor seizure control after epilepsy surgery. This study explored the effect of presurgical anxiety or depression on two- and five-year seizure control outcomes.

Methods: Adult subjects were enrolled between 1996 and 2001 in a multicenter prospective study to evaluate outcomes of resective epilepsy surgery.

Ten-Year Prevalence and Incidence of Urinary Incontinence in Older Women: A Longitudinal Analysis of the Health and Retirement Study.

Objectives: To measure the incidence of urinary incontinence (UI) over 10 years in older women who did not report UI at baseline in 1998, to estimate the prevalence of female UI according to severity and type, and to explore potential risk factors for development of UI.

Design: Secondary analysis of a prospective cohort.

Setting: Health and Retirement Study.

Final analysis of a phase II study of modified FOLFIRINOX in locally advanced and metastatic pancreatic cancer.

Background: Modifications of FOLFIRINOX are widely used despite the absence of prospective data validating efficacy in metastatic disease (metastatic pancreatic cancer (MPC)) or locally advanced pancreatic cancer (LAPC). We conducted a multicentre phase II study of modified FOLFIRINOX in advanced pancreatic cancer to assess the impact of dose attenuation in MPC and efficacy in LAPC.

Methods: Patients with untreated MPC or LAPC received modified FOLFIRINOX (irinotecan and bolus 5-fluorouracil reduced by 25%).

Viral load monitoring and antiretroviral treatment outcomes in a pediatric HIV cohort in Ghana.

Background: HIV-infected children in sub-Saharan Africa may be at a high risk of staying on a failing first-line regimen and developing drug-resistance HIV variants due to lack of routine viral load monitoring. We investigated whether cumulative viral load, measured as viremia copy-years (VCY) could predict morbidity in a setting where viral load is not routinely monitored.

Methods: This was a single-center prospective observational longitudinal study of HIV-infected children initiating antiretroviral therapy (ART) at the Pediatric HIV/AIDS Care program at Korle-Bu Teaching Hospital in Accra, Ghana.

Influence of Sub-Daily Variation on Multi-Fractal Detrended Fluctuation Analysis of Wind Speed Time Series.

Using multi-fractal detrended fluctuation analysis (MF-DFA), the scaling features of wind speed time series (WSTS) could be explored. In this paper, we discuss the influence of sub-daily variation, which is a natural feature of wind, in MF-DFA of WSTS. First, the choice of the lower bound of the segment length, a significant parameter of MF-DFA, was studied.

Sankofa pediatric HIV disclosure intervention cyber data management: building capacity in a resource-limited setting and ensuring data quality.

Prevalence of pediatric HIV disclosure is low in resource-limited settings. Innovative, culturally sensitive, and patient-centered disclosure approaches are needed. Conducting such studies in resource-limited settings is not trivial considering the challenges of capturing, cleaning, and storing clinical research data.

HIV knowledge, stigma, and illness beliefs among pediatric caregivers in Ghana who have not disclosed their child's HIV status.

The majority of HIV-infected children in sub-Saharan Africa have not been informed of their HIV status. Caregivers are reluctant to disclose HIV status to their children because of concern about the child's ability to understand, parental sense of guilt, and fear of social rejection and isolation. We hypothesized that the low prevalence of pediatric HIV disclosure in Ghana is due to lack of accurate HIV information and high HIV stigma among caregivers.

Multiple types of motives don't multiply the motivation of West Point cadets.

Although people often assume that multiple motives for doing something will be more powerful and effective than a single motive, research suggests that different types of motives for the same action sometimes compete. More specifically, research suggests that instrumental motives, which are extrinsic to the activities at hand, can weaken internal motives, which are intrinsic to the activities at hand. We tested whether holding both instrumental and internal motives yields negative outcomes in a field context in which various motives occur naturally and long-term educational and career outcomes are at stake.

Mood, anxiety, and incomplete seizure control affect quality of life after epilepsy surgery.

Objective: We examined the complex relationship between depression, anxiety, and seizure control and quality of life (QOL) outcomes after epilepsy surgery.

Methods: Seven epilepsy centers enrolled 373 patients and completed a comprehensive diagnostic workup and psychiatric and follow-up QOL evaluation. Subjects were evaluated before surgery and then at 3, 6, 12, 24, 48, and 60 months after surgery.

Parotid gland lymphoma: prognostic analysis of 2140 patients.

Objectives/hypothesis: Assess the demographic, clinical, and pathologic features of patients with parotid gland lymphoma and their prognostic importance using US population-based data.

Study Design: Retrospective cohort study.

Methods: Patients were selected from the Surveillance, Epidemiology, and End Results program database between the years of 1973 and 2008, and individual characteristics were compared using univariate and multivariate Cox proportional hazards models.

FOLFIRINOX for locally advanced and metastatic pancreatic cancer: single institution retrospective review of efficacy and toxicity.

Although FOLFIRINOX significantly increases survival in metastatic pancreatic cancer (MPC) compared to gemcitabine (Conroy et al. N Engl J Med 364:1817-1825, 2011), toxicities have tempered enthusiasm for its use in full doses. To assess the impact of dose attenuations on toxicity and efficacy, we reviewed our institution's experience with FOLFIRINOX in locally advanced pancreatic cancer (LAPC) and MPC.

Surgical residency and attrition: defining the individual and programmatic factors predictive of trainee losses.

Background: Voluntary resident attrition remains problematic despite recent changes in postgraduate general surgery training, including reduction of work hours.

Study Design: We conducted a prospective study of all postgraduate year (PGY)-1 and -2 trainees on the 2008 American Board of Surgery resident roster (ABS-RR) who completed the National Study of Expectations and Attitudes of Residents in Surgery (NEARS) survey after the American Board of Surgery In-Training Examination (ABSITE) in 2008 or 2009.

Results: Among 2,222 PGY-1 and -2 residents on the 2008 ABS-RR, 2,033 completed the NEARS survey in 2008 or 2009 (91.

Polycystic ovary syndrome in adolescence: impaired glucose tolerance occurs across the spectrum of BMI.

Context: Polycystic ovary syndrome (PCOS) is a chronic condition with metabolic manifestations spanning the reproductive years.

Objective: We sought to examine glucose metabolism, irrespective of the presence of obesity in a cohort of adolescent girls with PCOS.

Design: One hundred adolescents were assessed for PCOS in a multi-specialty adolescent PCOS program.

Human POLB gene is mutated in high percentage of colorectal tumors.

Previous small scale sequencing studies have indicated that DNA polymerase β (pol β) variants are present on average in 30% of human tumors of varying tissue origin. Many of these variants have been shown to have aberrant enzyme function in vitro and to induce cellular transformation and/or genomic instability in vivo, suggesting that their presence is associated with tumorigenesis or its progression. In this study, the human POLB gene was sequenced in a collection of 134 human colorectal tumors and was found to contain coding region mutations in 40% of the samples.

Model for end-stage liver disease score predicts adverse events related to ventricular assist device therapy.

Background: The Model for End-stage Liver Disease (MELD) score is a marker of multisystem organ dysfunction. It has been used to predict outcomes in patients undergoing hepatic and nonhepatic interventions. End-stage heart disease exhibits a varying degree of multiorgan dysfunction, which impacts the adverse events related to ventricular assist device (VAD) therapy.

Comprehensive analysis of variables affecting delayed gastric emptying following pancreaticoduodenectomy.

Introduction: Delayed gastric emptying (DGE) occurs commonly following pancreaticoduodenectomy (PD), and criteria for its clinical diagnosis have recently been standardized by an international consensus group. We evaluated 24 operative and peri-operative variables to assess which were independent risk factors for DGE development. Secondarily, we also examined DGE incidence over time and evaluated the consensus guidelines' ability to diagnose DGE in patients with complicated post-operative courses.

Nuclear expression of S100A4 calcium-binding protein increases cholangiocarcinoma invasiveness and metastasization.

Unlabelled: Cholangiocarcinoma (CCA) carries a severe prognosis because of its strong invasiveness and early metastasization. In several patients, otherwise eligible for surgical resection, micrometastasis are already present at the time of surgery. The mechanisms responsible for CCA invasiveness are unclear.

Differential hypoxic regulation of hypoxia-inducible factors 1alpha and 2alpha.

The hypoxia-inducible transcription factors (HIF) 1α and HIF-2α play a critical role in cellular response to hypoxia. Elevated HIF-α expression correlates with poor patient survival in a large number of cancers. Recent evidence suggests that HIF-2α appears to be preferentially expressed in neuronal tumor cells that exhibit cancer stem cell characteristics.

Allosteric aptamers: targeted reversibly attenuated probes.

Aptamers are unique nucleic acids with regulatory potentials that differ markedly from those of proteins. A significant feature of aptamers not possessed by proteins is their ability to participate in at least two different types of three-dimensional structure: a single-stranded folded structure that makes multiple contacts with the aptamer target and a double-helical structure with a complementary nucleic acid sequence. We have made use of this structural flexibility to develop an aptamer-based biosensor (a targeted reversibly attenuated probe, TRAP) in which hybridization of a cis-complementary regulatory nucleic acid (attenuator) controls the ability of the aptamer to bind to its target molecule.
