Ferrite-encapsulated nanoparticles along with secure photothermal functionality regarding multimodal imaging-guided atherosclerotic back plate neovascularization therapy.
Prostate-specific membrane antigen (PSMA) imaging is characterized by superior accuracy compared to conventional imaging for identification of nodal and distant metastases in prostate cancer. The majority of international clinical guidelines recommend PSMA positron emission tomography/computed tomography for patients experiencing biochemical recurrence, even at low prostate-specific antigen values, to identify candidates for salvage therapies. However, its use in for primary staging is still not recommended.
Urolithiasis has a significant impact on patients' health-related quality of life (HRQoL).

To develop a core patient-reported outcome measure (PROM) using modern psychometric methods to quantify the impact of urolithiasis and different treatments.

Adult patients with urinary calculi, attending urology departments, covering all index categories and treatment spectrum, participated during different development phases. The pilot instrument was created from potential items (phases 1 and 2) within the conceptual framework. The instrument was pretested (phase 3) and then underwent psychometric evaluation in two parts (phases 4 and 5).

The validity and reliability of the new PROM were assessed using Rasch measurement theory (RUMM 2030 statistical software) and traditional analyses.

In total, 683 patients (median age 51 yr, range 18-92 yr) participated during different phases. The initial 60-item draft (five scales) was completed by 212 patients (phase 4). A revised 25-item draft was produced after removal re a common condition for which various treatment options are available. The condition and treatments have a significant impact on a patient's quality of life. This can be measured objectively using a valid and reliable patient-reported outcome measure (PROM) developed using modern methods. We have developed a PROM that provides helpful and accurate measurement useful for all stakeholders.

Platelet volume has been shown to prognostic value in patients with colorectal cancer. However, the changes of other platelet-associated biomarkers in rectal cancer patients, before and after the neoadjuvant chemoradiation therapy (NACRT), remain unclear. Epalrestat In this study, we investigated the prognostic value of platelet-associated biomarkers in rectal cancer patients with NACRT.

A total of 75 patients with locally advanced (T3-4 or N+) rectal cancer (LARC) cancer were selected and followed up from the Affiliated Cancer Hospital of Zhengzhou University between June 2013 and September 2016. The data of platelet-associated biomarkers, including the platelet count, platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), mean platelet volume (MPV), and platelet distribution width (PDW) both pre- and post- NACRT, were collected. The associations between these platelet-associated biomarkers and the overall survival (OS), as well as disease-free survival (DFS) of patients, were analysed. Patients were divided into groups with high or low values of the platelet-associated biomarkers, and the outcomes were compared by using Cox regression and Kaplan-Meier analysis.

We found that pre-PLR (HR 4.104; 95%CI 1.411-11.421; P=0.009) and pre-LMR (HR 0.384; 95%CI 0.124-1.185; P=0.066) could predict the OS in LARC patients after NACRT by multivariate Cox regression analysis, a cut-off value of pre-PLR>7.02 and pre-LMR ≤7.10 could be used as independent prognostic factors for OS by Kaplan-Meier method. The pre-MPV value could be used as an independent prognostic factor for DFS by Kaplan-Meier analysis (P=0.037). Moreover, post-CEA was correlated with OS and DFS in LARC patients with NACRT.

In LARC patients with NACRT, the pre-PLR and pre-LMR are independent prognostic factors for OS, while pre-MPV has predictive value for DFS.

Most studies showed local control of approximately 75% with no evidence of improved overall survival. Gastrointestinal toxicities could be significant, ranging up to 22% for acute toxicities≥grade 3+ and 44% for late toxicities≥grade 3+. Currently, no standardized guidelines for treatment and management scheme. We conducted a systemic review of published prospective and retrospective trials to evaluate the efficacy, safety, technical data, and discuss future directions.
The use of MRI for radiotherapy planning purposes is growing but image acquisition using radiotherapy set-ups has impaired image quality. Whether differences in image acquisition set-up could modify organ contouring has not been evaluated. Therefore, we aimed to evaluate differences in contouring between paired of image sets that were acquired in the same scanning session using different parameters.

Ten patients underwent RT treatment planning with MRI co-registration. MRI was carried out using two different set-ups during the same session, MRI radiotherapy set-ups and MRI diagnostic set-ups. Prostates and rectums were retrospectively contoured in both image sets by 5 radiation oncologists and 4 radiologists. Intra-observer analysis was carried out comparing organ volumes, the Dice coefficient and hausdorff distance values between two contouring rounds. Inter-observer analysis was carried out by comparing individual contours to a generated STAPLE consensus contour, which is considered the gold standard reference.

No significant differences were observed between MRI acquisition set-ups. Significant differences were observed for the dice and hausdorff parameters, comparing individual contours to the STAPLE consensus contour, when analysing diagnostic images between rounds, although raw values were similar.

Prostate and rectum contours did not differ significantly when using diagnostic or radiotherapy MRI acquisition set-ups.
