ABSTRACT
Objective To explore the potential common mechanism and active ingredients of Reduning Injection against SARS, MERS and COVID-19 through network pharmacology and molecular docking technology. Methods The TCMSP database was used to retrieve the chemical components and targets of Artemisiae Annuae Herba, Lonicerae Japonicae Flos and Gardeniae Fructus in Reduning Injection. The gene corresponding to the target was searched by UniProt database, and Cytoscape 3.8.2 was used to build a medicinal material-compound-target (gene) network. Three coronavirus-related targets were collected in the Gene Cards database with the key words of "SARS""MERS" and "COVID-19", and common target of three coronavirus infection diseases were screened out through Venny 2.1.0 database. The common targets of SARS, MERS and COVID-19 were intersected with the targets of Reduning Injection, and the common targets were selected as research targets. Protein-protein interaction (PPI) network map were constructed by Cytoscape3.8.2 software after importing the common targets into the STRING database to obtain data. R language was used to carry out GO biological function enrichment analysis and KEGG signaling pathway enrichment analysis, histograms and bubble charts were drew, and component-target-pathway network diagrams was constructed. The key compounds in the component-target-pathway network were selected for molecular docking with important target proteins, novel coronavirus (SARS-CoV-2) 3CL hydrolase, and angiotensin-converting enzyme II (ACE2). Results 31 active compounds and 207 corresponding targets were obtained from Reduning Injection. 2 453 SARS-related targets, 805 MERS-related targets, 2 571 COVID-19-related targets, and 786 targets for the three diseases. 11 common targets with Reduning Injection: HSPA5, CRP, MAPK1, HMOX1, TGFB1, HSP90AA1, TP53, DPP4, CXCL10, PLAT, PRKACA. GO function enrichment analysis revealed 995 biological processes (BP), 71 molecular functions (MF), and 31 cellular components (CC). KEGG pathway enrichment analysis screened 99 signal pathways (P < 0.05), mainly related to prostate cancer, fluid shear stress and atherosclerosis, hepatocellular carcinoma, proteoglycans in cancer, lipid and atherosclerosis, human T-cell leukemia virus 1 infection, MAPK signaling pathway, etc. The molecular docking results showed that the three core active flavonoids of quercetin, luteolin, and kaempferol in Reduning Injection had good affinity with key targets MAPK1, PRKACA, and HSP90AA1, and the combination of the three active compounds with SARS-CoV-2 3CL hydrolase and ACE2 was less than the recommended chemical drugs. Conclusion Reduning Injection has potential common effects on the three diseases of SARS, MERS and COVID-19. This effect may be related to those active compounds such as quercetin, luteolin, and kaempferol acting on targets such as MAPK1, PRKACA, HSP90AA1 to regulate multiple signal pathways and exert anti-virus, suppression of inflammatory storm, and regulation of immune function.Copyright © 2022 Drug Evaluation Research.

ABSTRACT
Cancer remains one of the most prevalent diseases in the United States and a leading cause of death. Large prospective studies have found significant correlations between dietary intake and cancer. Chronic inflammation promotes pro-cancer inflammatory environments and nutrition can influence inflammation, with the intake of certain food items increasing inflammatory biomarkers. The objective of this research was to explore the relationship between inflammatory diet score measured by the Dietary Inflammatory index and all-cause mortality, cancer-specific mortality, and cancer recurrence among cancer survivors. Web of Science, Medline, CINHAL, and PsycINFO databases were searched to collect potentially eligible sources that focus on dietary inflammation and cancer outcomes. All sources were uploaded to Covidence software and screened by two independent blinded reviewers. The quality of the sources was assessed using the Newcastle Ottawa scale and relevant data was extracted and transferred to the Comprehensive Meta Analysis software and a random effects model was used to perform meta-analysis. Of the 1444 studies imported into the Covidence software, 13 passed all the screening stages and were included in the final analysis. Eight studies reported on pre-diagnosis diet while five others reported on postdiagnosis diet. Five studies reported on colorectal cancer, four on breast cancer, two on ovarian cancer, one on endometrial cancer and one on prostate cancer. Meta-analysis of the studies found that being in the highest postdiagnosis DII score indicating pro-inflammatory diet significantly increased the risk of all-cause death among cancer survivors by 33.5% (HR = 1.335, 95% CI = 1.049, 1.698, n = 6). Analysis did not show a statistically significant association between DII score and cancer mortality or recurrence (HR = 1.097, 95% CI = 0.939, 1.281, n = 6). Analysis by cancer subtype found a significant correlation between postdiagnosis DII score and all-cause mortality among the breast cancer survivors (HR = 1.335, 95% CI = 1.041, 1.711, n = 3) though there were no significant associations between DII and the outcomes of interest from the other cancer types. The meta-analysis concludes that being in the highest postdiagnosis DII score group significantly increased the risk of all-cause death among cancer survivors. This suggests that risk of all-cause mortality could be reduced for cancer survivors by consuming more anti-inflammatory food components and reducing consumption of pro-inflammatory foods. These findings also warrant more research in this field to clarify the relationship between dietary inflammation as measured by the DII and cancer outcomes, particularly cancer-specific mortality.
ABSTRACT
Background: coronaviral pandemic (COVID-19) induced by severe acute coronaviral syndrome 2 has imminent consequences for COVID-19 patients. To determine the effect of this pandemic on oncological treatment, Netherlands cancer patients performed a national study . Method(s): From 11 April 2020 to 11 Jan 2021, the oncological care perspective was discussed by an online study. The survey included 20 questions on four topics: patient characteristics, hospital engagement, COVID-19 and COVID-19 problems. Result(s): A total of 2418 (64.53%) patients were female and the remainder (57.5%) were <50 years of age. The most prevalent cancer diagnosis were haematological malignancies (26.1%), breast cancer (22.8%) and other cancers (19.2%). Depending on their illness environment, 34.7% of patients had incurable conditions while 21.6% and 31.8% had curable or healed diseases. The (expected) result of their illness was 'unknown' for 11.9% of patients. According to outpatient environment, 1691 (45.1%) patients have been oncologically examined and have taken follow-up, contrasted with 529 (14.1%) and 1527 (40.8%) patients presently or pending for therapy. Conclusion(s): This is the first research exploring cancer patients' experiences after the COVID-19 pandemic in Iraq. The research indicates the major effect of COVID-19 on oncological treatment, showing the need for psycho-oncological assistance during this pandemic.Copyright © 2020 Ubiquity Press.

ABSTRACT
PURPOSE: This qualitative study aimed to understand the impact of the coronavirus disease 2019 pandemic from March to November 2020 on healthcare delivery and clinical trials for genitourinary (GU) cancers in Australia. METHODS: Annually a pre-conference workshop is hosted by the Australian New Zealand Urogenital and Prostate Cancer Trials Group for supportive care health professionals. In November 2020, those that selected to attend were invited to participate in a focus group. Workshop and focus group discussions were recorded and transcripts were analyzed thematically. RESULTS: Seventy-two individuals involved in GU cancer care and clinical trials took part. Participants described negative changes to GU cancer care and clinical trials from the pandemic due to reduced clinical services and increased wait times. Trial recruitment was paused temporarily during lockdowns, and standard treatment protocols were used to limit hospital visits. Trial process changes included electronic capture of informed consent, home delivery of oral medications, and delegations of assessments. These changes increased administrative activity for clinical trial teams and Human Research Ethics Committees. A transition to telehealth enabled continuity of service delivery and trials but reduced the opportunity for face-to-face patient consultations with increasing concern about the failure to detect supportive care needs. CONCLUSION: The pandemic has prompted a critical review of service delivery and clinical trials for people with GU cancers.
ABSTRACT
Introduction: Drug repurposing is an effective strategy for identifying the use of approved drugs for new therapeutic purposes. This strategy has received particular attention in the development of cancer chemotherapy. Considering that a growing body of evidence suggesting the cholesterol-lowering drug ezetimibe (EZ) may prevent the progression of prostate cancer, we investigated the effect of EZ alone and in combination with doxorubicin (DOX) on prostate cancer treatment. Methods: In this study, DOX and EZ were encapsulated within a PCL-based biodegradable nanoparticle. The physicochemical properties of drug containing nanoparticle based on PCL-PEG-PCL triblock copolymer (PCEC) have been exactly determined. The encapsulation efficiency and release behavior of DOX and EZ were also studied at two different pHs and temperatures. Results: The average size of nanoparticles (NPs) observed by field emission scanning electron microscopy (FE-SEM) was around 82±23.80 nm, 59.7±18.7 nm, and 67.6±23.8 nm for EZ@PCEC, DOX@PCEC, and DOX+EZ@PCEC NPs, respectively, which had a spherical morphology. In addition, DLS measurement showed a monomodal size distribution of around 319.9, 166.8, and 203 nm hydrodynamic diameters and negative zeta potential (-30.3, -6.14, and -43.8) mV for EZ@PCEC, DOX@PCEC, and DOX+EZ@PCEC NPs, respectively. The drugs were released from the NPs sustainably in a pH and temperature-dependent manner. Based on the MTT assay results, PCEC copolymer exhibited negligible cytotoxicity on the PC3 cell line. Therefore, PCEC was a biocompatible and suitable nano-vehicle for this study. The cytotoxicity of the DOX-EZ-loaded NPs on the PC3 cell line was higher than that of NPs loaded with single drugs. All the data confirmed the synergistic effect of EZ in combination with DOX as an anticancer drug. Furthermore, fluorescent microscopy and DAPI staining were performed to show the cellular uptake, and morphological changes-induced apoptosis of treated cells. Conclusion: Overall, the data from the experiments represented the successful preparation of the nanocarriers with high encapsulation efficacy. The designed nanocarriers could serve as an ideal candidate for combination therapy of cancer. The results corroborated each other and presented successful EZ and DOX formulations containing PCEC NPs and their efficiency in treating prostate cancer.
ABSTRACT
Introduction & Objectives: The incidence of prostate cancer, both in the world and in the Russian Federation, tends to increase. In the Republic of Bashkortostan in 2021, 699 patients with this diagnosis were registered. 19.6% of patients had stage IV disease at the time of diagnosis. 5818 patients were registered, of which 361 died within a year. The effectiveness of hormonal treatment of common prostate cancer has time limitations, after which there is a development of resistance to castration and progression of the disease. To date, drugs such as kabazitaxel, sipuleucel-T vaccine, abiraterone, enzalutamide and radium-223 have been approved for use in metastatic CRPC. The purpose of the work: analysis of the experience of systemic radiotherapyand Radium - 223 patients with mCRPC in the Republic of Bashkortostan in 2021. Material(s) and Method(s): Analysis of patients who received systemic radiotherapy Radium - 223 in the Republic of Bashkortostan according to medical documentation and research data. In 2021, Radiy-223 radiotherapy was performed on 7 patients diagnosed with mCRPC. Median age 63.14 years. All patients met the criteria for treatment, i.e. had castration-resistant prostate cancer with bone metastases, without visceral metastases. All patients had concomitant pathology from the cardiovascular system, respiratory tract, endocrine system. According to the previous surgical treatment, patients were distributed as follows: orchidectomy - 4, prostatectomy - 1 and 2 patients underwent tumor biopsy. By morphology: Glisson 6 - 2 patients, Glisson 7 - 1, Glisson 8 - 3, Glisson 10 - 1. 4 patients were referred to Xofigo for radiologically confirmed progression, 3 patients were progressingin height at PSA levels. Result(s): 1 patient previously received 1 line of systemic therapy, 5 patients received 2 lines, 1 patient received 3 lines of therapy. 6 patients received all 6 courses of radiotherapy, 1 patient did not complete treatment due to COVID 19. He is expected to complete therapy. All patients are currently alive with no signs of disease progression. Serious side effects were not registered. Conclusion(s): The "therapeutic window" for the prescription of radium-223 is the period before the appearance of visceral metastases and decline of the somatic status. To achieve the maximum benefit from the appointment of radium-223, it is necessary to conduct >=5 cycles of therapy, which is possible in 1-2 treatment lines. It is necessary to select patients carefully for radiotherapy - Radium 223.Copyright © 2022 European Association of Urology. Published by Elsevier B.V.
ABSTRACT
INTRODUCTION AND OBJECTIVE: Randomised comparative outcomes are unavailable for focal therapy in localised prostate cancer. IP4 CHRONOS is an RCT aimed to optimise recruitment of patients dependent upon clinician and patient equipoise. METHOD(S): Patients with clinically significant localised prostate cancer could opt for IP4-CHRONOS-A or IP4-CHRONOS-B. IP4- CHRONOS-A randomised patients 1:1 between focal therapy(HIFU or cryotherapy) versus radical therapy(radiation or prostatectomy). Using a multi-arm-multistage(MAMS)design, IP4-CHRONOS-B randomised between focal alone(FTA) and focal combined with neoadjuvant medication (12 weeks of finasteride [FTF] or bicalutamide [FTB]). We report the pilot phase outcomes on feasibility of randomisation, early safety outcomes relative to treatment and genito-urinary functional outcomes following over 12 months treatment in IP4-CHRONOS-B. IP4-CHRONOS had ethics committee approval and was registered(ISRCTN17796995). RESULT(S): Following COVID-19 adjustments, IP4-CHRONOSA did not meet its feasibility target. Having randomised 36 patients via10 sites with a recruitment rate (95% CI) of 18% (13-23) & randomisation rate of 97%(86-100). IP4-CHRONOS-B did meet its target, randomising 64 patients across 7 sites with a recruitment rate of 43% (35-52) &randomisation rate of 100%(94-100). The only patients to withdraw were randomised to the radical arm of IP4-CHRONOS-A(4 [22%]) All patients in IP4-CHRONOS-B were compliant with neoadjuvant treatment.Only 1 patient reported CTCAE V4.0 grade>=3 adverse event(AE) in IP4-CHRONOS-A following radical treatment, another patient in each arm reported a serious adverse event(SAE) following treatment. 1 &3 patients reported an AE &SAE following FTB. 2 and 3 patients reported an AE &SAE following FTA. No patients reported any AE or SAE event following FTF. Figure 1 demonstrates generally well preserved genito-urinary function following focal treatment+/-neoadjuvant treatment. CONCLUSION(S): IP4-CHRONOS evaluated patient and physician equipoise regarding focal therapy. Traditional randomisation was not feasible due to strong patient preferences, while a MAMS RCT investigating the role of neoadjuvant agents combined with focal therapy was.
ABSTRACT
INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic led to the delay of routine medical care, including cancer screening, beginning in March of 2020. While screening rates for several cancers, including prostate cancer, rapidly recovered after the first wave of the COVID-19 pandemic, the degree to which this recovery was realized in different populations remains unknown. We sought to determine the association of the COVID-19 pandemic with prostate cancer screening, particularly for traditionally underserved patients. METHOD(S): We performed a retrospective cohort study using electronic health records (EHR) data from the Optum EHR database for male patients between the ages of 55-69 eligible for prostate cancer screening from quarter 1 (Q1) of 2016 through Q2 of 2021. We excluded men with a prior diagnosis of prostate cancer. We performed multivariable analysis to estimate screening over time, adjusting for patient age, race, ethnicity, Census division of residence, and insurance status. RESULT(S): A total of 7,361,765 patients were included. After adjusting for patient demographics, the percentage of eligible patients with prostate cancer screening decreased from 2.2% in Q4 of 2019 to 1.3% in Q2 of 2020. There was a rebound in screening to 2.4% in Q3 of 2020, which is similar to baseline levels, and a subsequent decline to 1.6% in Q2 of 2021. This trend was seen even after stratifying based on age, race, ethnicity, division, and insurance status (Figure 1). CONCLUSION(S): A 40% decline in prostate cancer screening in Q2 of 2020 was observed during the first wave of the pandemic. This returned to baseline by Q3 of 2020. Subsequent decline was seen again through Q2 of 2021, which also coincides with the second wave of COVID-19. This trend was unaffected by patient characteristics, such as age, race, insurance status, or division of residence. While these data suggest that the peak of the pandemic impacted prostate cancer screening trends similarly across different patient demographic groups, further study is required to breakdown if this was due to social distancing, decreased clinic volumes, or other factors.
ABSTRACT
Introduction & Objectives: In 2020, the COVID-19 pandemic brought innumerous challenges to healthcare systems, with reallocation of professionals and suspension of normal activity. This led to a more difficult patient access to primary care, with postponed routine examinations and delayed referrals to specialized consultations. We are now experiencing the results of such delays, with patients arriving later at specialized outpatient appointments. Our objectives were to compare pathological staging patterns of prostate cancer between pre and post-COVID-19 years. Material(s) and Method(s): At a tertiary center, we gathered all pathological data from prostate biopsies (PB) and radical prostatectomy (RP) from 01-01-2019 to 30-06-2022, and compared pathological specimens between 2019 and post-COVID-19 years (2021 and 2022). Result(s): We collected data from 850 PB and 401 RP. During the first pandemic year (2020), we observed a 34.5% and 24.4% reduction in PB and RP (192 PB in 2020 vs 293 in 2019;96 RP in 2020 vs 127 in 2019), respectively. In 2021 and first semester of 2022, the number of PB and RP returned to pre-pandemic values. In post-pandemic years (2021 and 2022) (PPY) PB resulted in less ISUP1 tumors (20.6% in PPY vs 26.62% in 2019) and more poorly differentiated tumors (21.6% ISUP34 in PPY vs 15.7% in 2019), with a 75% increase in cribriform pattern detection. Regarding RP specimens, we identified a 150% increase in high-grade tumors (ISUP34: 9.9% In PPY vs 3.9% in 2019) and 66% increase in extraprostatic extension (54.3% in PPY vs 36.2% in 2019). Nodal involvement was detected in 4.6% (n=15) in PPY compared to 3.9% (n=5) in 2019. Conclusion(s): We are currently observing a change in prostate cancer disease characteristics compared to pre-pandemic years, with patients arriving with higher-grade tumors and more locally advanced featuresCopyright © 2022 European Association of Urology.

ABSTRACT
INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic placed a significant burden on the US healthcare system. Moreover, many healthcare systems triaged cases based on the severity of disease. Therefore, we assessed the impact of the COVID-19 pandemic on prostate cancer management according to the International Society of Urological Pathology (ISUP) grade groups. METHOD(S): We retrospectively analyzed the National Cancer Database (NCDB) for patients with prostate cancer between 2018- 2020. We divided our cohort into "Pre-Pandemic" (2018/2019) and "Pandemic" (2020) periods. Men were classified according to their ISUP grade group at diagnosis. Hospital characteristics and patient-level clinical and sociodemographic variables were extracted. Our primary outcome was the utilization of definitive treatment (surgery or radiation) versus expectant management (active surveillance, watchful waiting, or no treatment). We performed multivariable logistic regressions to predict the type of management for each ISUP grade group across the two periods adjusting for clinical and socioeconomic covariates. RESULT(S): A total of 398,719 men with a diagnosis of prostate cancer were reported during the "Pre-Pandemic" (70.6%) and "Pandemic" (29.4%) periods. Overall, 24.5% had an ISUP 1, 30.6% an ISUP 2, 18.2% an ISUP 3, 13% ISUP 4, and 13.8% ISUP 5 disease (Table 1). Treatment was less likely during the "Pandemic" compared to the "Pre-Pandemic" period for ISUP grade group 1 (aOR 0.80;95% CI 0.77 - 0.83;p-value <0.001), for ISUP grade group 2 (aOR 0.85;95% CI 0.81 - 0.89;p-value <0.001) and for ISUP grade group 3 (aOR 0.87;95% CI 0.80 - 0.96;p-value <0.003). However, no differences in treatment trends were found for ISUP grade groups 4 and 5 across the two time periods. CONCLUSION(S): During the COVID-19 pandemic, patients with prostate cancers ISUP grade groups 1, 2, and 3 were more likely to receive expectant management than definitive treatment;however, this was not true for patients with more aggressive diseases. This finding suggests a high capacity of facilities to appropriately risk stratify and prioritize higher-risk cases during a public health emergency. A limitation of our study is the inability to assess the treatment trends of men diagnosed in the last 2020 quarter due to the lack of follow-up.
ABSTRACT
INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic likely affected the healthcare system's ability to deliver prostate cancer care services. Herein, we sought to evaluate prostate cancer's stage and grade migration resulting from the COVID-19 pandemic. METHOD(S): We retrospectively analyzed the National Cancer Database (NCDB) for men with prostate cancer between 2018-2020. We divided our cohort into the "Pre-Pandemic" (2018/2019) and "Pandemic" (2020) periods. Stage and grade of prostate cancer were stratified according to the severity of disease: PSA value (<=20 vs. >20), clinical T stage (cT1-T2 vs. cT3-T4), clinical M stage (cM0 vs. cM1), International Society of Uropathology (ISUP) grade group (ISUP 1-2-3 vs. ISUP 4-5), and D'Amico risk classification (low risk vs. intermediate & high risk). Pearson's chi-square test was used to assess differences in the distribution of stage and grade across the two periods. We performed multivariable logistic regressions to estimate the effect of the "Pandemic" period on stage and grade distribution adjusting for clinical and socioeconomic covariates. RESULT(S): A total of 398,719 men were diagnosed with prostate cancer during the "Pre-pandemic" (70.6%) and "Pandemic" (29.4%) periods (Table 1). On univariable comparisons, an increase in stage/ grade across the two periods was demonstrated (all p<0.001). After adjusting for covariates, compared to the "Pre-pandemic", the "Pandemic" period was associated with increased odds of PSA >20 levels (aOR 1.06;95% CI 1.03 - 1.08;p-value <0.001), cT3-4 stages (aOR 1.12;95% CI 1.08 - 1.16;p<0.001), cM1 stage (aOR 1.15;95% CI 1.12 - 1.18;p<0.001), ISUP grade group 4 or 5 (aOR 1.03;95% CI 1.01 - 1.05;p=0.003) and D'Amico Intermediate & High risk groups (aOR 1.15;95% CI 1.13 - 1.18;p<0.001). CONCLUSION(S): The COVID-19 pandemic was associated with significant changes in the distribution of both stage and grade of prostate cancer. Possible explanations for this migration include a better selection of patients for prostate biopsy during the pandemic or changes in prostate cancer screening patterns.
ABSTRACT
Introduction & Objectives: With the introduction of new modalities for prostate biopsies, detection rates of prostate cancer have been increased on one hand but on the other hand there are still some institutions where transperineal prostate (TP) biopsies cannot be offered due to limitations such as lack of expertise, absence of facilities, financial limitations, immense pressure on health system and especially during Covid pandemic. The aim of our study is to look at the prostate cancer detection rates of mpMRI (multi-parametric) prostate lesions amenable to transrectal ultrasound prostate biopsies (TRUS) and whether or not it can be offered in institutions with limited options. Material(s) and Method(s): Retrospectively we looked at the results of 95 patients with mean age of 67.8 years, mean prostate volume 46.5 cc, median PSA 7.2 ng/mL. TRUS biopsies amenable lesions on MRI prostate comprised of all peripheral or posterior zone lesions with: PIRADS II with rising PSA (1 patient);PIRADS >3 with PSAD of > 0.12 (14 patients), PIRADS IV (42 patients) and PIRADS V (33 patients). In addition to these there were 5 patients where PIRADS category was not clear. All patients underwent prostate biopsies (from both lobes) as per departmental protocol. Result(s): We found 0%, 42.9%, 68.4% and 90.3% in PIRADS II, PIRADS >III with PSAD >0.12, PIRADS IV and PIRADS V, respectively. In those where no PIRADS category was given 2 (40%) patients had the positive histology for prostate cancer. Overall prostate cancer detection rate was 65.2%. A direct proportional link was found between PIRADS category and prostate cancer detection. Only 2 patients with negative prostate biopsies agreed to have TP prostate biopsies repeated, that showed Gleason score 6 in PIRADS IV lesion and benign histology in other patient with PIRADS V lesion. It is also found that 15-50% of lesions in contralateral lobe have not been picked up by the MRI scan that came positive for prostate cancer (see table).(Table Presented) Most common to least common, the following histology was note: Gleason score (GS) > 8 (36 patients, 58%), GS 4+3 (10 patients, 16.1%), GS 3+4 (12 patients, 19.3%), GS 6 (4 patients, 6.4%) and high grade PIN (1 patient, 1.6%). Conclusion(s): It can be concluded that TRUS prostate biopsies can be utilized in a productive way by achieving highly satisfactory results in patients who has MRI prior to biopsies. A careful selection and a proper reading of MRI are warranted to achieve the good outcomes. TRSU biopsies are helpful in those departments with limitations in carrying out TP prostate biopsiesCopyright © 2022 European Association of Urology. Published by Elsevier B.V.
ABSTRACT
Objective. To evaluate the effectiveness of the detection of malignant neoplasms (MNPs) when implementing secondary preventive measures against cancer in municipal healthcare facilities during the COVID-19 pandemic. Material and methods. The model of the Volga Federal District (VFD) of Russia was used to conduct analytical and statistical studies of the rates of active detection of MNPs in the municipal healthcare facilities in 2019-2020. The demographic indicators and state statistics data, which were publicly available on the Internet, on the official websites of the territorial health authorities, oncology dispensaries of the VFD subjects, were comparatively analyzed. A database (State Registration Certificate of the Russian Federation under No. 2021621834/01.09.21) was used to evaluate the effectiveness of secondary preventive measures against cancer during the COVID-19 pandemic in 2020. Results. Compared to 2019, the COVID-19 pandemic caused a 2.1% expansion in the network of patients' examination rooms mainly due to an increase in the number of male rooms by 5.6% and mixed-type rooms by 6.3%. The number of mid-level healthcare workers that provided the functioning of patients' examination rooms rose by 5.2%;the proportion of specialists trained in the area of oncology decreased by 20% (85% in 2019 and 68.1% in 2020). The introduction of restrictive measures determined a statistically significant (p<0.05) decline in the proportion of people who had undergone a primary medical examination in the male (32.9%), female (35.6%), and general (34.7%) populations. The mean frequency of detected MNPs in 2019 and 2020 was 0.91 and 0.76, respectively (a 16.5% decrease). There was an increase in the incidence of lung cancer (LC) (a 4.2% increase) and a reduction in that of breast cancer (BC) (a 56.6% decrease). A comparative assessment of changes in the rate of active detection of MNPs in healthcare facilities at all health levels revealed a negative increase in its mean value in 2020 versus 2019 for colorectal cancer (CRC) (-25.6%), LC (-25.0% ), BC (-11.6%), cervical cancer (CC) (-12.4%), and prostate cancer (PC) (-2.1%). The prognosis of the number of actively detected MNP cases during the pandemic shows that, provided that the effectiveness of MNP detection rates remains the same as in 2019;there were no CRC (n = about 1100 cases), LC (n=1050), BC (n=1470), CC (n=300), and PC (n=300) cases in the VFD in 2020. An analysis of the effectiveness of secondary preventive measures against LC and BC in the VFD showed that among the number of newly diagnosed cases of a disease in 2019, there were LC (92.3%) and BC (75.1%) cases in the municipal healthcare facilities;there were LC (100%) and BC (60.9%) cases during the COVID-19 pandemic. Conclusion. The COVID-19 pandemic led to a decline in the number of participants in preventive activities. Considering the uneven territorial spread of COVID-19, the development of a methodology for the preventive measures adapted to a pandemic, mainly in the municipal healthcare facilities, is an extremely important area of preventive healthcare activities.Copyright © 2022, Media Sphera Publishing Group.

ABSTRACT
Background: Prostate cancer is one of the most common cancers worldwide. The proper management of this cancer during the coronavirus disease 2019 (COVID-19) or similar outbreaks could be a serious challenge. Proper timing of surgery, radiotherapy, and other medical modalities are essential in providing the most effective treatment. Objective(s): This systematic review aimed at evaluating the proper management of prostate cancer during the COVID-19 outbreak. Method(s): This study was conducted from 2019 to 2022. An internet search was conducted using the keywords: Diagnosis, man-agement, radical prostatectomy, radiotherapy, hormone ablation therapy, chemotherapy and prostate cancer, and COVID-19. The visited databases included PubMed, Scopus, Web of Sciences, Google Scholar, and Scientific Information Database. The review was performed based on the preferred reporting items for a systematic review and meta-analyses (PRISMA) guidelines. Result(s): Postponing the biopsy for up to three months and adopting of non-invasive diagnostic methods were likely reasonable during the COVID-19 pandemic. Patients with cancer were more prone to severe injuries and were more likely to have serious compli-cations. Surgery, radiation therapy, brachytherapy, palliative radiation, hormone ablation therapy, and chemotherapy were among the pre-institutional treatments that had to be performed according to medical protocols as well as health and professional guide-lines. Conclusion(s): It was recommended that the prostate cancer screening should not be performed for asymptomatic men during the COVID-19 outbreak. It was also suggested that the treatment should be performed in the shortest possible time and in the safest way.Copyright © 2023, Author(s).
ABSTRACT
Cancer management is highly dependent on the immune status of the patient. During the COVID-19 pandemic, a large number of people suffered from anxiety and depression, especially cancer patients. The effect of depression on breast cancer (BC) and prostate cancer (PC) patients, during the pandemic has been analyzed in this study. Levels of proinflammatory cytokines (IFN-γ, TNF-α, and IL-6) and oxidative stress markers malondialdehyde (MDA) and carbonyl content (CC) were estimated in patients' serum samples. Serum antibodies against in vitro hydroxyl radical (â¢OH) modified pDNA (â¢OH-pDNA-Abs) were estimated using direct binding and inhibition ELISA. Cancer patients showed increased levels of proinflammatory cytokines (IFN-γ, TNF-α, and IL-6) and oxidative stress markers (MDA and CC levels), which were further significantly enhanced in cancer patients with depression compared to normal healthy (NH) individuals. Increased levels of â¢OH-pDNA-Abs were detected in breast cancer (0.506 ± 0.063) and prostate cancer (0.441 ± 0.066) patients compared to NH subjects. Serum antibodies were found to be significantly elevated in BC patients with depression (BCD) (0.698 ± 0.078) and prostate cancer patients with depression (PCD) (0.636 ± 0.058). Inhibition ELISA also exhibited significantly high percent inhibition in BCD (68.8% ± 7.8%) and PCD (62.9% ± 8.3%) subjects compared to BC (48.9% ± 8.1%), and PC (43.4% ± 7.5%) subjects. Cancer is characterized by enhanced oxidative stress and increased inflammation, which may be exaggerated with COVID-19 related depression. High oxidative stress and compromised antioxidant homeostasis exerts alterations in DNA, leading to formation of neo-antigens, subsequently leading to the generation of antibodies. COVID-19 pandemic related depression needs to be addressed globally for improved cancer patient care and cancer disease management.
ABSTRACT
Introduction: MicroUS is a new imaging technique that may have potential to reliably monitor prostate disease and therefore release capacity in MRI departments. Firstly, however, it is essential to identify which healthcare staff may be suitable to learn to use this modality. Based on previous evidence, UK sonographers may be well placed to harness this resource. Topic: Currently, there is sparse evidence on the performance of MicroUS for monitoring prostate disease but early findings are encouraging. Although its uptake is increasing, it is believed that only two sites in the UK have MicroUS systems and only one of those uses just sonographers to undertake and interpret this new imaging technique. Discussion: UK sonographers have a history of role extension dating back several decades and have proven repeatedly that they are reliable and accurate when measured against a gold standard. We explore the background of UK sonographer role extension and postulate that sonographers are best placed to adopt and embed new imaging techniques and technology into routine clinical practice. This is of particular importance given the dearth of ultrasound focussed radiologists in the UK. To effectively introduce challenging new work streams, multi-professional collaboration in imaging, alongside sonographer role extension, will ensure precious resources are maximised thus ensuring optimum patient care. Conclusion: UK sonographers have repeatedly demonstrated reliability in many areas of role extension in various clinical settings. Early data indicate that the adoption of MicroUS for use in prostate disease surveillance may be another role suited to sonographers.
ABSTRACT
INTRODUCTION: The associations among SARS-CoV-2 infection, vaccination and total serum prostate serum antigen (PSA) levels in men undergoing screening for prostate cancer are unknown. METHODS: A retrospective analysis of data from a large health maintenance organization. Records of individuals aged 50 to 75 years with two serum PSA tests taken between March 2018 and November 2021 were included. Individuals with prostate cancer were excluded. Changes in PSA levels were compared between individuals who had at least 1 SARS-CoV-2 vaccination and/or infection between the two PSA tests and individuals who did not have an infection and were not vaccinated between the two PSA tests. Subgroup analyses were performed to assess the impact of the elapsed time between the event and the second PSA test on the results. RESULTS: The study and control groups included 6,733 (29%) and 16 286 (71%) individuals, respectively. Although the median time between PSA tests was shorter in the study vs. the control group (440 vs. 469 days, P<.001), PSA elevation between the tests was higher in the study group (0.04 vs. 0.02, P<.001). The relative risk for PSA elevation ≥1 ng/dL was 1.22 (95% CI 1.1, 1.35). Among individuals who were vaccinated, PSA increased by 0.03 ng/dL (IQR -0.12, 0.28) and 0.09 ng/dL (IQR -0.05, 0.34) after 1 and 3 doses, respectively (P<.001). Multivariate linear regression showed that SARS-CoV-2 events (ß 0.043; 95% CI 0.026-0.06) were associated with a greater risk for PSA elevation, after adjusting for age, baseline PSA and days between PSA tests. CONCLUSION: SARS-CoV-2 infection and vaccinations are associated with a slight increase in PSA, with the third anti-COVID vaccine dose having a more prominent impact, but its clinical significance is unknown yet. Any significant increase in PSA must be investigated and cannot be dismissed as secondary to SARS-CoV-2 infection or vaccination.
ABSTRACT
AIMS: The optimal method of measuring cancer extent in prostate cancer (PCa) biopsies is unknown. METHODS AND RESULTS: Nine hundred eighty-one men with clinically localised PCa managed conservatively were reviewed with follow up. The number of positive cores (NPC), the Maximum Cancer Length in a core (MCL), Total Cancer Length (TCL), and percentage of positive cores (%+cores) was calculated and univariate and multivariate analysis performed using prostate-specific antigen (PSA), T-stage, and Gleason score. The presence of stromal gaps (SG) was recorded. Univariate models were run where SG made a difference to the MCL. All variables showed significant association with PCa death in univariate models. In multivariate models, incorporating PSA, T-stage, and Gleason score, only %+cores was a significant predictor of outcome, with a 10% increase in %+cores resulting in a hazard ratio (HR) of 1.07 (likelihood-ratio test P > Χ2 = 0.01). There were 120 patients where SG made a difference to the MCL and a total of 20 events in this group. Including SG, on univariate analysis the median MCL was 10 mm and HR was 1.16 (P = 0.007), not including SG, the median MCL was 6 mm and HR was 1.23 (P = 6.3 × 10-4 ). Inclusion or exclusion of SG made no significant difference to TCL as a predictor of outcome. CONCLUSION: Cancer extent is a strong predictor of PCa death but only %+cores added to the multivariate model. Expressed as a fraction of NPC/total number of cores, this is the simplest method of assessment, which we favour over more complicated methods in nontargeted biopsies.

This is a presentation of the case of a patient who underwent 18F-fluorocholine positron emission/computed tomography to stage a prostate cancer with incidentally found bilateral pneumonia. A high prevalence of incidental pneumonia is very probable under the current circumstance of coronavirus disease-2019 (COVID-19) pandemic, and oncological patients are at increased risk of COVID-19 with poorer outcome. The lung inflammatory burden in the case of COVID-19 infection can be demonstrated by 18F-fluorocholine.
ABSTRACT
This article is a systematic review of mental health in urologic oncology patients with prostate cancer (PCa), bladder cancer (BC), renal cell carcinoma (RCC), testicular cancer (TC), or penile cancer (PeCa). For all pathologies, a focus on increasing quality of life post-treatment demonstrated a positive impact in reducing Mental Health Illness (MHI) prevalence. Cancer specific mental health care may be given to patients to reduce suicide risk in BC patients and sexual identify and masculinity counseling may improve mental health for TC or PeCa patients. In order to better accommodate patient's mental health needs when undergoing GU cancer treatment, we recommend incorporation of mental health metrics such as questionnaires to assess early treatment of MHI, a greater emphasis on psychosocial support with the patient's loved ones, peers, and healthcare team, alongside advising healthy habits such as exercise which has been shown to drastically reduce MHI incidence across all pathologies. We hope that these measures conducted by urologists and oncologists, alongside possible coordination with psychiatrists and psychologists for psychotherapy, psychopharmacology, and neuro-stimulation treatment modems may be helpful in the long term to reduce MHI incidence in urology oncology patients. Given the higher incidence of MHI in oncology patients and in the patient population after the Covid-19 pandemic, MHI awareness in the sphere of urologic oncologic treatment continues to be crucial when creating a collaborative treatment platform for patients.
