With the rapid influx of novel anti-cancer agents, phase I clinical trials in oncology are evolving. Historically, response rates on early phase trials have been modest with the clinical benefit and ethics of enrolment debated. However, there is a paucity of real-world data in this setting.

To better understand the changing landscape of phase I oncology trials, we performed a retrospective review at our institution to examine patient and trial characteristics, screening outcomes, and treatment outcomes.

We analyzed all consecutive adult patients with advanced solid organ malignancies who were screened across phase I trials from January 2013 to December 2018 at a single institution. During this period, 242 patients were assessed for 28 different trials. Median age was 64 years (range 30-89) with an equal sex distribution. Among 257 screening visits, the overall screen failure rate was 18%, resulting in 212 patients being enrolled onto a study. Twenty-six trials (93%) involved immunotherapeutic agents or urvival in our cohort are superior to historically reported rates and comparable to contemporaneous studies. Severe treatment-related toxicity was relatively uncommon, and treatment-related mortality was rare.Bedside diagnosis of skin cancer remains a challenging task. The real-time noninvasive technology of optical coherence tomography (OCT) masters a high diagnostic accuracy in basal cell carcinoma (BCC) but a lower specificity in recognizing imitators and other carcinomas. We investigate the delicate signal of papillary dermis using an in-house developed ultrahigh resolution OCT (UHR-OCT) system with shadow compensation and a commercial multi-focus high resolution OCT (HR-OCT) system for clinical BCC imaging. We find that the HR-OCT system struggled to resolve the dark band signal of papillary dermis where the UHR-OCT located this in all cases and detected changes in signal width. UHR-OCT is able to monitor extension and position of papillary dermis suggesting a novel feature for delineating superficial BCCs in pursuit of a fast accurate diagnosis. SR-4370 manufacturer Comprehensive studies involving more patients are imperative in order to corroborate results.

Although aging is strongly associated with both heart failure and a decline in gait speed, a definition of slowness incorporating an age-related decline has yet to be developed. We aimed to define an event-driven cut-off for the relative decline in gait speed against age-adjusted reference values derived from the general population and evaluate its prognostic implications.

Standardized gait speed (SGS) was defined as the median gait speed stratified by age, sex, and height in 3777 elderly (age≥65years) individuals without a history of cardiovascular diseases (Tokyo Metropolitan Institute of Gerontology-Longitudinal Interdisciplinary Study on Aging general population cohort). The mortality event-driven optimal cut-off of the SGS ratio (actual gait speed divided by the respective SGS) was defined using FRAGILE-HF cohort data and externally validated using Kitasato cohort data, comprising 1301 and 1247 hospitalized elderly patients with heart failure, respectively. Using FRAGILE-HF data, the optimal SGS ratio cut-off was determined as 0.527. In the Kitasato cohort, SGS ratio<0.527 was associated with a higher 1year [hazard ratio (HR) 1.70, 95% confidence interval (CI) 1.07-2.72, P=0.024] and long-term (HR 1.46, 95% CI 1.05-2.02, P=0.024) mortality rate, independent of pre-existing covariates.

Gait speed was significantly declined in patients with heart failure, even after taking age and sex-related decline into account. A SGS ratio of 0.527 is a validated cut-off for slowness independently associated with mortality in patients with heart failure age ≥65.

We report here our experience of using pegylated granulocyte colony stimulating factor (peg-GCSF) for peripheral blood stem cell (PBSC) mobilization in children.

A total of nine children suffering from high-risk/relapsed solid tumors were mobilized with chemotherapy and peg-GCSF (100 microgram/kg single dose). Mean age was 7.7 years (range 2-15 years).The mean time from peg-GCSF administration to PBSC harvest was 9.7 days. Adequate stem cells (median dose 26.9 million/kg) could be harvested in all children by a single apheresis procedure. No major adverse events observed.

It is feasible and safe to mobilize PBSC with peg-GCSF in children with cancer.

Data are steadily accruing that demonstrate that intestinal tumors are frequently derived from multiple founding cells, resulting in tumors comprised of distinct ancestral clones that might cooperate or alternatively compete, thereby potentially impacting different phases of the disease process.

We sought to determine whether tumors with a multi-ancestral architecture involving at least two distinct clones show increased tumor number, growth, progression, or resistance to drug intervention.

Mice carrying the Min allele of Apc were generated that were mosaic with only a subset of cells in the intestinal epithelium expressing an activated form of PI3K, a key regulatory kinase affecting several important cellular processes. These cells were identifiable as they fluoresced green, whereas all other cells fluoresced red.

Cell lineage tracing revealed that many intestinal tumors from our mouse model were derived from at least two founding cells, those expressing the activated PI3K (green) and those which didre necessary to fully develop personalized medicine.Risk for heart disease increases with advanced age and differs between sexes, with females generally protected from heart disease until menopause. Despite these epidemiological observations, the molecular mechanisms that underlie sex-specific differences in cardiac function have not been fully described. We used high throughput transcriptomics in juvenile (5 weeks), adult (4-6 months), and aged (18 months) male and female mice to understand how cardiac gene expression changes across the life course and by sex. While male gene expression profiles differed between juvenile-adult and juvenile-aged (254 and 518 genes, respectively), we found no significant differences in adult-aged gene expression. Females had distinct gene expression changes across the life course with 1835 genes in juvenile-adult and 1328 in adult-aged. Analysis of differentially expressed genes (DEGs) suggests that juvenile to adulthood genes were clustered in cell cycle and development-related pathways in contrast to adulthood-aged which were characterized by immune-and inflammation-related pathways. Analysis of sex differences within each age suggests that juvenile and aged cardiac transcriptomes are different between males and females, with significantly fewer DEGs identified in adult males and females. Interestingly, the male-female differences in early age were distinct from those in advanced age. These findings are in contrast to expected sex differences historically attributed to estrogen and could not be explained by estrogen-direct mechanisms alone as evidenced by juvenile sexual immaturity and reproductive incompetence in the aged mice. Together, distinct trajectories in cardiac transcriptomic profiles highlight fundamental sex differences across the life course and demonstrate the need for the consideration of age and sex as biological variables in heart disease.

Long-term breast cancer survivors are at risk for cardiotoxicity after treatment, but there is insufficient evidence to provide long-term (~10years) cardiovascular disease (CVD) screening recommendations. We sought to evaluate a tri-modality CVD screening approach.

This single-arm, feasibility study enrolled 201 breast cancer patients treated ≥6years prior without CVD at diagnosis. Patients were sub-grouped cardiotoxic (left-sided) radiation (RT), cardiotoxic (anthracycline-based) chemotherapy, both cardiotoxic chemotherapy and RT, and neither cardiotoxic treatment. Patients underwent electrocardiogram (EKG), transthoracic echocardiogram with strain (TTE with GLS), and coronary artery calcium computed tomography (CAC CT). The primary endpoint was preclinical or clinical CVD.

Median age was 50 (29-65) at diagnosis and 63 (37-77) at imaging; median interval was 11.5years (6.7-14.5). Among sub-groups, 44% had no cardiotoxic treatment, 31.5% had cardiotoxic RT, 16% had cardiotoxic chemotherapy, and 8.5% hadf breast cancer survivors than previously recognized.

Childhood patients have high risks for developing debilitating somatic and mental health side-effects as a consequence of the many different approaches employed in treating their cancer. Early recognition and close monitoring of clinical and psychological problems are essential in planning appropriate interventions and preventing further deterioration.

ePROtect was established as an easy-to-use application for daily self-reporting of symptoms during cancer therapy. ePROtect includes six to eight questions pertaining to seven common symptoms appetite loss, fatigue, nausea, pain, physical functioning, cognitive impairments and sleep quality. The case of a child diagnosed with Burkitt leukemia developing chemotherapy-induced oral mucositis in home care is presented to show the therapeutic impact of early symptom detection with a daily web-based tool.

This case highlights how electronic patient-reported outcome measures (PROM) can directly facilitate patient care in real time and might be incorporated in future clinical routine.

In order to obtain functionalities beyond the capability of magnetic forces and torques exerted on magnetic materials used in these robotic devices, electronics need to be also integrated into them. However, their capabilities and power sources are still very limited compared to their larger-scale counterparts due to their much smaller sizes. Here, groups of milli/centimeter-scale wireless magnetic modules are shown to enable on-site electronic circuit construction and operation of highly demanding wireless electrical devices with no batteries, that is, with wireless power. Moreover, the mobility of the modular components brings remote modification and reconfiguration capabilities. When these small-scale robotic modules are remotely assembled into specific geometries, they can achieve, if not impossible, challenging electrical tasks for individual modules. Using such a method, several wireless and battery-free robotic devices are demonstrated using milli/centimeter-scale robotic modules, such as a wireless circuit to power light-emitting diodes with lower external fields, a device to actuate relatively high force-output shape memory alloy actuators, and a wireless force sensor, all of which can be modified on-site.
