The goal of developing a PET dedicated to the brain (CareMiBrain) has evolved from its initial approach to diagnosis and monitoring of dementias, to the more ambitious of creating a revolutionary clinical pathway for the knowledge and personalized treatment of multiple neurological diseases. The main innovative feature of CareMiBrain is the use of detectors with continuous crystals, which allow a high resolution determination of the depth of annihilation photons interaction within the thickness of the scintillation crystal. The technical validation phase of the equipment consisted of a pilot, prospective and observational study whose objective was to obtain the first images (40 patients), analyze them and make adjustments in the acquisition, reconstruction and correction parameters, comparing the image quality of the CareMiBrain equipment with that of the whole-body PET-CT. Thanks to the team meetings and the joint analysis of the images, it was possible to detect its weak points and some of its causes. The calibration, acquisition and processing processes, as well as the reconstruction, were optimized, the number of iterations was set to achieve the best signal-to-noise ratio, the random correction was optimized and a post-processing algorithm was included in the reconstruction algorithm. The main technical improvements implemented in this phase of technical validation carried out through collaboration of the Services of Nuclear Medicine and Neurology of the Hospital Clínico San Carlos with the Spanish company Oncovision will be exposed in a project financed with funds from the European Union (Horizon 2020 innovation program, 713323). Mentorship in the surgical field has been increasingly recognized as a crucial component of career success. Distance mentorship models may be utilized to overcome geographic limitations, increase mentorship access, and strengthen mentoring relationships in surgery. This review aimed to identify the scope of literature on distance mentoring in surgery, the range of its application, its effectiveness, and any gaps in the literature that should be addressed in order to enhance mentorship in the surgical field. A comprehensive PubMed review was performed in January 2021 on distance mentorship of students, trainees, and surgeons in the surgical field. Reviews, replies, and non-English articles were excluded. Data was extracted regarding publication year, author's country, specialty, subjects, aim of mentorship model, and efficacy. 134 total studies met inclusion and exclusion criteria. Most studies were published in 2020, written by authors in the United States, from general surgery, and featured an expertentorship is particularly important because of decreased face-to-face opportunity. Future studies in the surgical field should investigate distance mentoring as a means of increasing mentorship for professional development.Vitiligo is an acquired depigmenting disorder. Vitiligo universalis is a rare form responsible for significant aesthetic damage. https://www.selleckchem.com/products/odq.html To date, the exact pathogenesis remains unknown. Its treatment, a real challenge, consists rather in removing the still pigmented areas. We report a case of a patient followed for stable vitiligo universalis from an early age who presented with repigmentation shortly after initiation of hemodialysis. A case report is a scientific article describing one or more patients with unusual clinical presentations. In recent years, the number of case reports in publications has decreased. In this study, we analyze the publication of case reports in journals of Endocrinology during the years 2010, 2015 and 2019. The Pubmed web was browsed for clinical journals of Endocrinology, those published in English and/or Spanish being selected, and the relevant variables analyzed. Of 84 analyzed journals, 51 accepted cases for publication, 29 did not, and 4 did so only in exceptional cases. In 2010, 11,754 articles were published, of which 709 were clinical cases (6.9% of the total); in 2015, a total of 14,594 articles of which 655 were clinical cases (5.8% of the total); and in 2019 a total of 14,110 articles, of which 472 were clinical cases (4.6% of the total). In journals demanding payment for the publishing of clinical cases, case reports represented 9% of all articles, and in free journals, 3% (P<.05). There has been a decline in publication of case reports in journals of Endocrinology in recent years, both in absolute and relative terms. Even though the cases described by these reports are, by definition, exceptional, the decline of their publication implies a significant loss of scientific information and clinical knowledge regarding certain pathologies.

The impact of clinical trial participation on overall survival is unclear. We hypothesized that enrollment in a therapeutic drug clinical trial is associated with longer overall survival in patients with metastatic non-small cell lung cancer (NSCLC). We linked electronic medical record and Washington State cancer registry data to identify patients with metastatic NSCLC diagnosed between January 1, 2007, and December 31, 2015 who received treatment at a National Cancer Institute-designated cancer center. The exposure was trial enrollment. The primary outcome was overall survival, defined as the date of second-line treatment initiation to date of death or last follow-up. We used a conditional landmark analysis starting at the date of second-line treatment initiation and propensity scores with inverse probability of treatment weighting to estimate the association between trial enrollment and survival. Of 215 patients, 40 (19%) participated in a second-line trial. Trial participants were more likely to be never smokers (45% vs 27%), have a good performance status (88% vs 77%) and have EGFR (48% vs 14%) and ALK mutations (8% vs 5%) than nonparticipants. Trial participants had similar overall survival to nonparticipants (HR 1.05; 95% CI, 0.72, 1.53; p=0.81) after adjusting for sociodemographic and disease characteristics. Accounting for the immortal time bias and selection bias, trial participation does not appear detrimental to survival. This finding may be reassuring to patients and supports programs and policies to improve clinical trial access.
