The patterns of association between age and suicide rate vary by country, subpopulation and gender, and over time. To shed light on factors associated with these differences, we analysed suicide data from four populations, two 'Western' (Australia, the United States [US]) and two Asian (Japan and Hong Kong). We computed suicide rates in five-year age-groups (between 10 and 14 years and 85+ years) for men and women separately, and present graphical representations of the age patterns during selected five-year periods...

BACKGROUND: Multimodal prehabilitation is a preoperative conditioning intervention in form of exercise, nutritional assessment, whey protein supplementation, and anxiety-coping technique. Despite recent evidence suggesting that prehabilitation could improve functional capacity in patients undergoing colorectal surgery for cancer, all studies were characterized by a relatively small sample size. The aim of this study was to confirm what was previously found in three small population trials...

Importance: Human papillomavirus (HPV)-negative oropharyngeal squamous cell carcinoma (OPSCC) has shown resistance to conventional concurrent chemoradiation (CRT) therapy and carries a relatively poor prognosis in comparison with HPV-positive disease, with decreased locoregional control and overall survival (OS). In the present analysis, we examine whether upfront surgical resection improves overall survival in a large national sample. Objective: To compare survival outcomes among patients with newly diagnosed cT1-2 N1-2b HPV-negative OPSCC when treated with primary surgical resection vs CRT...

Background: Trimodality bladder preservation therapy (BPT) in muscle invasive bladder cancer (MIBC) includes a maximal transurethral resection followed by concurrent chemoradiotherapy as an alternative to radical cystectomy (RC) in appropriately selected patients, or as a treatment option in non-cystectomy candidates. Several chemotherapy regimens can be used in BPT, but little is known about current practice patterns. Objective: To describe utilization patterns of BPT and associated survival outcomes in MIBC...

While radical cystectomy (RC) with pelvic lymph node dissection (PLND) represents the accepted gold standard for the treatment of muscle-invasive bladder cancer, this treatment approach is associated with significant morbidity. As such, bladder preservation strategies are often utilized in patients who are either deemed medically unfit due to significant comorbidities or whom decline management with RC and PLND secondary to its associated morbidity. In a select group of patients, meeting strict criteria, bladder preservation approaches may be employed with curative intent...

BACKGROUND/PURPOSE: To retrospectively evaluate the failure patterns of multimodality bladder-preserving therapy in patients with muscle-invasive bladder cancer. METHODS: Patients with muscle-invasive bladder cancer underwent maximal transurethral resection of bladder tumor and induction chemotherapy, followed by concurrent chemoradiotherapy (CCRT). Radiotherapy was given with 45 Gy to the pelvis, 50.4 Gy to the bladder, and 64.8 Gy to the tumor bed. Three protocols of trimodality treatment were used: Protocol A, three cycles of cisplatin and fluorouracil (CF), followed by CCRT with 6 weekly cisplatin; Protocol B, three cycles of weekly paclitaxel plus CF, followed by CCRT with 6 weekly paclitaxel and cisplatin; Protocol C, three cycles of gemcitabine and cisplatin, followed by CCRT with 6 weekly cisplatin...

Hereditary renal cell carcinomas (RCCs) are life-threatening disorders not only for the patients but also for their relatives. Birt-Hogg-Dubé syndrome (BHD) is an autosomal dominant disorder caused by germline mutations in the folliculin gene (FLCN). The protein product, FLCN, functions as a tumor suppressor, and the affected patients have high risks of developing multiple RCCs. The carcinogenic mechanisms stemming from FLCN dysfunction have been investigated using rodent models and human RCC tissues. However, very limited information has been available about in vitro signaling of human renal cells with genetically mutant FLCN...

Populations of oscillators can display a variety of synchronization patterns depending on the oscillators' intrinsic coupling and the coupling between them. We consider two coupled symmetric (sub)populations with unimodal frequency distributions. If internal and external coupling strengths are identical, a change of variables transforms the system into a single population of oscillators whose natural frequencies are bimodally distributed. Otherwise an additional bifurcation parameter κ enters the dynamics...

Management of stage IIIA-N2 non-small cell lung cancer is still matter of ongoing controversy. The debate is flawed by the heterogeneity of this group of patients, lack of strong evidence from controlled trials, diverging treatment strategies, and hesitating estimation of prognosis. Surgery is credited a survival advantage in a trimodality setting. For many teams, N2 is by principle managed with induction chemotherapy, followed by surgery if the patient is down-staged. However, surgery remains a suitable option even in case of persistent N2...

Activatable multimodal probes that show enhancement of multiplex imaging signals upon interaction with their specific molecular target have become powerful tools for rapid and precise imaging of biological processes. Herein, we report a stimuli-responsive disassembly approach to construct a redox-activatable fluorescence/(19)F-MRS/(1)H-MRI triple-functional probe 1. The small molecule probe 1 itself has a high propensity to self-assemble into nanoparticles with quenched fluorescence, attenuated (19)F-MRS signal, and high (1)H-MRI contrast...

BACKGROUND: Environmentally influenced phenotypes, such as obesity and insulin resistance, can be transmitted over multiple generations. Epigenetic modifications, such as methylation of DNA cytosine-guanine (CpG) pairs, may be carriers of inherited information. At the population level, the methylation state of such "heritable" CpG sites is expected to follow a trimodal distribution, and their mode of inheritance should be Mendelian. METHODS: Using the Illumina Infinium 450 K DNA methylation array, we determined DNA CpG-methylation in blood cells from a family cohort 123 individuals of Arab ethnicity, including 18 elementary father-mother-child trios, we asked whether Mendelian inheritance of CpG methylation is observed, and most importantly, whether it is independent of any genetic signals...

We present reflection-mode bioimaging system providing complementary optical, photoacsoutic and acoustic measurements by acoustic detector after each laser pulse. While the photons absorbed within the sample provide optoacoustic (OA) signals, the photons absorbed by the external electrode of a detector provide the measurable diffuse reflectance (DR) from the sample and the probing ultrasonic (US) pulse. To demonstrate the in vivo capabilities of the system we present the results of complementary DR/OA/US imaging of a mouse tumor, head of a newborn rat, and the back of a newborn rat with 3...

Multimodal imaging guided synergistic therapy promises more accurate diagnosis than any single imaging modality, and higher therapeutic efficiency than any single one or their simple "mechanical" combination. Herein, we report a dual-stimuli responsive nanotheranostic based on a hierarchical nanoplatform, composed of mesoporous silica-coated gold nanorods (GNR@SiO2), Indocyanine Green (ICG), and 5-fluorouracil (5-FU), for in vivo multimodal imaging guided synergistic therapy. The 5-FU loaded ICG-conjugated silica-coated gold nanorods (GNR@SiO2-5-FU-ICG) was able to response specifically to the two stimuli of pH change and near-infrared (NIR) light irradiation...

During presurgical evaluation of pharmacoresistant partial epilepsies, stereoelectroencephalography (SEEG) records interictal and ictal activities directly but is inherently limited in spatial sampling. In contrast, scalp-EEG and MEG are less sensitive but provide a global view on brain activity. Therefore, recording simultaneously these three modalities should provide a better understanding of the underlying brain sources by taking advantage of the different sensitivities of the three recording techniques...
