Background: The advantages of active surveillance (AS) in low-risk prostate cancer (PC) have already been widely demonstrated. The 15-year results of the Prostate Testing for Cancer and Treatment (ProtecT) trial were published recently, reflecting worse oncological outcomes of their active monitoring programme (AMP) compared with radical prostatectomy (RP) or radiotherapy (RDT). Our objective was to analyse the survival of patients with International Society of Urological Pathology (ISUP) grade I PC depending on the treatment received and point out the differences between an AS protocol and the AMP established in the ProtecT trial.

This quantum interference (QI) directly translates into enhancement or suppression of conductance and offers the possibility of controlling this phenomenon through tailored synthesis. Hence, we set up synthetic methodologies to access a series of thiophene-fused helicenes with a well-defined positioning of the sulfur atoms, which control the occurrence of conducting, linearly conjugated as well as disrupted, cross-conjugated pathways.

Helical molecules have been proposed as candidates for producing spin-polarized currents, even at room conditions, due to their chiral asymmetry. However, describing their transport mechanism in single molecular junctions is not straightforward. In this work, we show the synthesis of two novel kinds of dithia[11]helicenes to study their electronic transport in break junctions among a series of three helical molecules: dithia[]helicenes, with = 7, 9, and 11 molecular units.

Mounting evidence indicates that indeed, the so-called Mediterranean diet (MedDiet) and regular physical activity likely both help reduce the risk of developing BC. For those who have already received a BC diagnosis, these interventions may decrease the risk of tumor recurrence after treatment and improve quality of life.

Under the hypothesis that nutritional stress through fasting might enhance the antitumour properties of at least some non-oncological agents, by screening drug libraries, we find that cholesterol biosynthesis inhibitors (CBIs), including simvastatin, have increased activity against cancers of different histology under fasting conditions. We show fasting's ability to increase CBIs' antitumour effects to depend on the reduction in circulating insulin, insulin-like growth factor-1 and leptin, which blunts the expression of enzymes from the cholesterol biosynthesis pathway and enhances cholesterol efflux from cancer cells.

Specific proteolytic cleavage of gasdermins generates an N-terminal that oligomerizes and forms pores in the cell membrane. Although pyroptosis has been widely described in mammals, the importance of gasdermins and gasdermin-like proteins in inducing cell death in other vertebrates, in invertebrates and in other taxa including fungi and bacteria is still being determined.

Our aim is to evaluate the survival of patients with high-risk PC treated with curative intent and to identify differences across ages at diagnosis.
Methods: We did a retrospective analysis of patients with high-risk PC treated with surgery (RP) or radiotherapy (RDT) excluding N+ patients.

Introduction: There is no population-based study that accounts for the number of radical prostatectomies (RP) carried out in Spain, nor regarding the morbidity and mortality of this intervention. Our objective is to study the morbidity and mortality of RP in Spain from 2011 to 2015 and to evaluate the geographic variation.
Material And Methods: We designed a retrospective observational study of all patients submitted to RP in Spain during five consecutive years (2011-2015).
The Hedgehog (Hh) pathway is essential for the embryonic development and homeostatic maintenance of many adult tissues and organs. It has also been associated with some functions of the innate and adaptive immune system. However, its involvement in the immune response has not been well determined.

The production is regulated by the androgen receptor (AR). It is speculated that androgen deprivation therapy (ADT) may protect patients affected by prostate cancer (PC) from SARS-CoV-2 infection.

However, concerns remain over possible negative impact on the patients' nutritional status. We assessed the feasibility and safety of a 5-day "Fasting-Mimicking Diet" (FMD) as well as its effects on body composition and circulating growth factors, adipokines and cyto/chemokines in cancer patients.

The performance of these devices is highly dependent on the sulfur atom topology, so a precise knowledge of the synthetic routes that may afford isomeric structures is necessary. We have studied the photocyclization pathway of both 2- and 3-styrylthiophenes on their way to thiahelicenes by experiment and theory.

Nevertheless, the molecular mechanisms through which HRG affects the efficiency of anti-HER2 therapies such as trastuzumab (Tz) and trastuzumab-emtansine (T-DM1) are currently unknown.
Methods: In the present study, we evaluate the molecular action of HRG toward fundamental scaffold proteins and several kinases in the signal transduction pathways triggered via HER2/HER3, which integrate precise and sequential steps to promote changes in cell morphology to impulse BC cell migration.
Acute zonal occult outer retinopathy (AZOOR) is a rare syndrome characterized by sudden onset of photopsia, scotomas, and abnormal electrophysiological tests, predominantly affecting young women. Although its pathogenesis remains unknown, auto-reactivity to retinal components is thought to mediate tissue damage. A 42-year-old woman presented with symptoms and examination consistent with the diagnosis of AZOOR.

Today, many efforts in the field of regenerative medicine focus on the use of platelet derivatives due to their ability to reactivate endogenous mechanisms supporting tissue repair. While their use in orthopedics continues, mechanisms of action and efficacy need further characterization.

We show here that the MYC-associated factor X, MAX, plays a repressive role in this network and operates through a MYC-independent binding to E-box-containing regulatory regions within the promoters of circadian BMAL1 targets. We further show that this "clock" function of MAX is required for maintaining a proper circadian rhythm and that MAX and BMAL1 contribute to two temporally alternating transcriptional complexes on clock-regulated promoters.

We used a modular assembly of fragments using Pd catalyzed coupling reactions and a final photocyclization step for the syntheses; this strategy gave us straightforward access to helicenes bearing thiophene end rings with either or topologies. Unequivocal structural characterization was carried out by X-ray crystallography.

Materials And Methods: We analyzed the data of 277 patients prospectively recruited in 11 hospitals undergoing RC initially managed according to local practice (Group I) and later within an ERAS program (Group II). Two main outcomes were defined: 90-day complications rate and LOS.
To further assess the influence of the weight after TURBT as a predictive factor for recurrence and progression in NMIBC. A cohort of patients with a first episode of NMIBC between 1999 and 2016 was analysed retrospectively. We studied the correlation between the tumour's size and weight, the time-dependent ROC curves for the optimal weight value for the prediction of recurrence and progression and their association with the risk of recurrence and progression at one and five years.
