The aim of this study was to validate contemporary grading systems, in particular, the Gleason grade group (GGG)5.

We retrospectively reviewed the clinicopathologic data of 176 patients who underwent radical prostatectomy and whose pathologic results were GGG 4 or 5. The endpoints were biochemical recurrence (BCR) and castration-resistant prostate cancer (CRPC).

The GGG 4 group was composed of 69 patients. click here The GGG 5 group consisted of 78 patients with GS 4+5 and 29 patients with GS 5+4 or higher. The 5-year BCR-free survival rates for men with GGG 4, GS 4+5, and GS 5+4 or higher were 59%, 54%, and 20%, respectively, and the 5-year CRPC-free survival rates were 98%, 100%, and 88%, respectively. Both the BCR- and CRPC-free survival rates were significantly higher in GS 4+5 than in GS 5+4 or higher (P< .001 and P= .002, respectively), but there were no significant differences between GGG 4 and GS 4+5 (P= .702 and P= .803, respectively). The multivariate analysis demonstrated that GS 5+4 or higher (hazard ratio, 3.4; P= .002) and lymphovascular invasion (hazard ratio, 3.4; P< .001) greatly affected BCR.

Our follow-up study revealed that men with GS 4+5 and those with GGG 4 had a similar prognosis. link2 However, there was a significant discrepancy in prognosis between GS 4+5 and GS 5+4 or higher. This suggested that GGG 4 and 5 in the contemporary prostate cancer grading system should be reviewed. Furthermore, lymphovascular invasion may be useful to subgroup these pathologically high-risk patients.

The present analysis aims to compare the impact of 18F-fluorocholine (

F-choline) and gallium-68 prostate-specific membrane antigen (

Ga-PSMA) positron emission tomography (PET)-computed tomography (CT)-guided metastases-directed therapies (MDTs) in patients with castration-sensitive oligorecurrent prostate cancer (PC).

Inclusion criteria were (1) histologically proven prostate adenocarcinoma; (2) evidence of biochemical relapse after primary tumor treatment; (3)≤ 3 hypermetabolic oligorecurrent lesions detected by

F-choline or

Ga-PSMA PET-CT; (4) PET-CT imaging performed in a single nuclear medicine department; (5) patients treated with upfront stereotactic body radiotherapy (SBRT) without hormone therapy; and (6) SBRT delivered with a dose per fraction≥ 5 Gy. In the case of oligoprogression (≤ 3 lesions outside the previous RT field) after MTD, a further course of SBRT was proposed; otherwise, androgen deprivation therapy (ADT) was administered.

A total of 118 lesions in 88 patients were analyzen the setting of oligorecurrent castration-sensitive PC, PSMA-PET-guided SBRT produced a higher rate of ADT-free patients when compared with the 18F-choline-PET cohort. Randomized trials are advocated.

To investigate the health-related quality of life of uro-oncologic patients whose surgery was postponed without being rescheduled during the coronavirus disease 2019 (COVID-19) pandemic.

From the March 1 to April 26, 2020, major urologic surgeries were drastically reduced at our tertiary-care referral hospital. In order to evaluate health-related quality-of-life outcomes, the SF-36 questionnaire was sent to all patients scheduled for major surgery at our department 3 weeks after the cancellation of the planned surgical procedures because of the COVID-19 emergency.

All patients included in the analysis had been awaiting surgery for a median (interquartile range) time of 52.85 (35-72) days. The SF-36 questionnaire measured 8 domains physical functioning (PF), role limitations due to physical health (PH), role limitations due to emotional problems (RE), energy/fatigue (EF), emotional well-being (EWB), social functioning (SF), bodily pain (BP), general health perceptions (GHP). When considering physical chaost operating rooms in Italy could be responsible for the increased anxiety and decrement in health status of oncologic patients. Without any effective solution, we should expect a new medical catastrophe-one caused by the increased risk of tumor progression and mortality in uro-oncologic patients.Accumulation of senescent cells has a causative role in the pathology of age-related disorders including atherosclerosis (AS) and cardiovascular diseases (CVDs). However, the concept of senescence is now drastically changing, and the new concept of senescence-associated reprogramming/stemness has emerged, suggesting that senescence is not merely related to "cell cycle arrest" or halting various cellular functions. It is well known that disturbed flow (D-flow) accelerates pre-mature aging and plays a significant role in the development of AS. We will discuss in this review that pre-mature aging induced by D-flow is not comparable to time-dependent aging, particularly with a focus on the possible involvement of senescence-associated secretory phenotype (SASP) in senescence-associated reprogramming/stemness, or increasing cell numbers. We will also present our outlook of nicotinamide adenine dinucleotides (NAD)+ deficiency-induced mitochondrial reactive oxygen species (mtROS) in evoking SASP by activating DNA damage response (DDR). MtROS plays a key role in developing cross-talk between nuclear-mitochondria, SASP, and ultimately atherosclerosis formation. Although senescence induced by time and various stress factors is a classical concept, we wish that the readers will see the undergoing Copernican-like change in this concept, as well as to recognize the significant contrast between pre-mature aging induced by D-flow and time-dependent aging.Microplastics (MPs) and nanoplastics (NPs) have attracted considerable attention in the recent years as potential threats to the ecosystem and public health. This review summarizes current knowledge of pathological events triggered by micro- and nano-plastics (MP/NPs) with focus on oxidative damages at different levels of biological complexity (molecular, cellular, tissue, organ, individual and population). Based on published information, we matched the apical toxicity endpoints induced by MP/NPs with key event (KE) or adverse outcomes (AO) and categorized them according to the Adverse Outcome Pathway (AOP) online knowledgebase. We used existing AOPs and applied them to highlight formal mechanistic links between identified KEs and AOs in two possible scenarios first from ecological, and second from public health perspective. Ecological perspective AOP based literature analysis revealed that MP/NPs share formation of reactive oxygen species as their molecular initiating event, leading to adverse outcomes such as growth inhibition and behavior alteration through oxidative stress cascades and inflammatory responses. Application of AOP on literature data related to public health perspective of MP/NPs showed that oxidative stress and its responding pathways, including inflammatory responses, could play the role of key events. However insufficient information prevented precise definitions of AOPs at this level. To overcome this knowledge gap, further mammalian model and epidemiological studies are necessary to support development and construction of detailed AOPs with public health focus.Peroxisome proliferator-activated receptors (PPARs) are a family of three nuclear hormone receptors (PPARα, PPARδ, and PPARγ) that are known to regulate expression of lipid metabolism and oxidative stress genes. Given their role in reducing oxidative stress in a variety of tissues, these genes are likely important for retinal homeostasis. This hypothesis has been further supported by recent studies suggesting that PPAR-activating drugs are protective against retinal degenerations. link3 The objective of the present study was to determine the role of PPARδ in the neuroretina. RNA-seq data show that Pparα and Pparδ are both expressed in the retina, but that Pparδ is expressed at 4-fold higher levels. Single-cell RNAseq data show that Pparδ is broadly expressed in all retinal cell types. To determine the importance of Pparδ to the retina, we generated retina-specific Pparδ knockout mice. We found that deletion of Pparδ had a minimal effect on retinal function or morphology out to 12 months of age and did not increase retinal sensitivity to oxidative stress induced by exposure to bright light. While data show that PPARδ levels were increased by the drug metformin, PPARδ was not necessary for metformin-induced protection from light damage. These data suggest that Pparδ either has a redundant function with Pparα or is not essential for normal neuroretina function or resistance to oxidative stress.Numerous studies have demonstrated positive therapeutic and economic outcomes associated with pharmacist-provided care. However, public policy on provider status with subsequent payment for non-dispensing services has been slow to reflect an expanded pharmacist role. It is important for the public to understand the value of a pharmacist outside of the drug distribution system. Pharmacists and other health care and public health practitioners must share this information to further knowledge and affect policies and systems that can most effectively include pharmacists fully in the health care system. The 3 main areas identified in which the pharmacist has economic impact are decreased total health expenditures, decreased unnecessary care, and decreased societal costs. Evidence supports the economic value of the pharmacist; however, public opinion and political movements supporting patients' access to pharmacist-provided care are variable. Strategies to advocate and effect change include advocating to elected leaders for policy change and advocating to other health professionals, patients, and community members to better their understanding of the positive economic value of pharmacist-provided care. Through prioritizing community outreach and legislator education, pharmacist advocates can leverage 3 key areas in which pharmacists have economic value to advance policy and increase patients' access to care.The purpose of this commentary is to describe the ideal role of 503B outsourcing facilities in the U.S. drug supply chain. We also address the challenges that 503B outsourcing facilities are facing that limit their utilization and offer possible solutions. Section 503B outsourcing facilities are emerging contributors in compounding owing to their ability to compound large quantities of medication without requiring patient-specific prescriptions. As such, they play a valuable role in the U.S. drug supply chain. The use of outsourcing facilities to compound ready-to-use drug products is gaining traction in hospitals and other health care systems. Outsourcing facilities help hospitals that are facing time and cost constraints owing to the evolving regulatory landscape around compounding. Although outsourcing facilities are assets to the drug supply chain, there are several challenges to their use. The lack of a finalized 503B Bulks List has led to outsourcing facilities being overly cautious in compounding products using bulk drug substances.
