%) over cabazitaxel in patients with docetaxel-pretreated, progressive mCRPC selected by PSMA and FDG PET/CT scans. PSMA TRT is emerging as a promising investigational therapy for mCRPC. The first randomized data with 177Lu-PSMA-617 (phase 2) have been presented, and the first phase 3 trial has completed accrual with radiographic progression-free and overall survival as dual primary endpoints. Multiple additional phase 3 trials of PSMA-TRT are starting and studies investigating optimal patient selection and combination therapy continue.
Personal treatment goals have been systematically investigated in psoriasis patients with active but not in controlled disease.
To explore patient needs in psoriasis patients with controlled disease due to biologic therapy with adalimumab, etanercept or ustekinumab.
Treatment needs in patients on adalimumab, etanercept or ustekinumab with a stable low disease activity for ≥6 months and preferably a Psoriasis Area and Severity Index (PASI) <5, were explored with the Patient Needs Questionnaire (PNQ). Goal importance was expressed as overall mean importance score, percentage of patients that reported a goal to be quite/very important, and per PNQ subscale. Data were analysed separately for treatment, gender, age group (<50 vs. ≥50 years), biologic naivety and willingness to participate in a pragmatic dose-reduction strategy.
Sixty-five patients were included. 'To be free of itching', 'to be healed of all skin defects' and 'to have confidence in the therapy' were rated quite/very important in 78.5% of the patients, followed by 'to have no fear the disease will progress' (75.4%) and 'to get better skin quickly' (75.4%). Goals related to the subscale 'confidence in healing' were still of high importance in controlled disease. Least importance was attributed towards social goals. For female patients, it was significantly more important than for males to 'feel less depressed' and 'be comfortable showing yourself more in public'.
Psoriasis patients with controlled disease still report substantial treatment needs, with high importance ascribed to confidence in healing. To apply personalized medicine, treatment needs should be explored on an individual level.

Treatment response following transarterial chemoembolization (TACE) is frequently evaluated with Liver Imaging Reporting and Data System Treatment Response (LR-TR) algorithm, but its association with patients' outcomes is not supported in the literature. The purpose of this study was to provide such data.
A retrospective analysis of 99 TACE patients with stage A/B hepatocellular carcinoma according to Barcelona-Clinic Liver Cancer staging system was performed. Two radiologists assessed LR-TR, while a third radiologist re-assessed divergent results. Overall survival (OS) and time to disease progression (TTP) were the primary endpoints of the study, while the Cox proportional hazard model was used for outcome analyses.
Interobserver agreement was substantial between the two readers with κ = 0.69 (95% CI 0.58-0.81). The median OS in viable, equivocal, and non-viable groups were 27, 27, and 73months, respectively (p < 0.001). However, after adjustment for confounding factors, there was no significant association between initial viable response and OS (HR 0.98 [95% CI 0.37-2.63], p = 0.97), while equivocal response remained statistically significant (HR 3.52. [95% CI 1.27-9.71], p = 0.015). No significant association was noted when viable and equivocal groups were analyzed in aggregate (HR 1.03 [95% CI 0.4-2.4], p = 0.96). The median TTP did not differ between non-viable and viable groups (23 vs 18months, respectively; p = 0.98). None of the analyzed predictors was associated with TTP.
Initial LR-TR response was not an independent predictor for OS nor TTP. The preliminary results suggest the necessity for more aggressive management of equivocal patients.

Gas station workers (GSWs) are exposed to carcinogenic agents. The aim was to study the association of high somatic chromosome alterations (CAs) rates in the blood of GSWs and the polymorphisms of three genes playing a role in DNA double-strand break repair.
This is a cross-sectional study with 114 GSWs and 115 age-matched controls. Cytogenetic analyses, blood exams, medical interviews and genotypes for RAD51/G135C (rs1801320), ATM/P1054R (rs1800057) and CHEK2/T470C (rs17879961) genes were performed.
The CA rate in GSWs was 9.8 CAs/1000 metaphases, and 19.1% of the workers had > 10 CAs per 1000 metaphases (group two). GSWs had decreased levels of monocytes (P = 0.024) in their blood exams. The number of variant alleles of the RAD51/G135C polymorphism was higher in GSWs (P = 0.011) compared to the controls, and were associated with enhanced number of CAs per worker (P = 0.008). No allele variant was found for CHEK2/T470C in this study.
The RAD51/G135C polymorphism appears to be related to genome instability in gas station workers. Increasing the knowledge of DNA repair gene variations involved in maintaining genomic stability in GSWs may be crucial for future cancer prevention.

Determination of the association between ica genes and phenotypic biofilm formation in staphylococcal isolates involved in conjunctivitis, their antibiotic resistance as well as detection of selected virulence characteristics adhesion to epithelial cells and in vitro cytotoxicity.
The study included 26 Staphylococcus aureus (SA) and 26 Staphylococcus epidermidis (SE) isolates. The presence of icaAD genes and ica operon was determined by the PCR assay. Phenotypic biofilm formation was verified using the microtitre plate assay. Antibiotic resistance was performed using the disc diffusion method. Staphylococcal ability to attach to host cells was assessed by flow cytometry. Cytotoxicity on epithelial cells was evaluated by LDH assay.
The ica genes were detected in 26.9% of SE and in 42.3% of SA isolates. Only 15.3% of isolates (SE) were positive for both the icaAD and the ica operon. Phenotypically, 19.2% of SE isolates were strong biofilm producers, among which three were both icaAD- and ica operon-positive. About 26.9% of SA isolates were strong biofilm producers. Methicillin resistance (MR) was detected in 34.6% of SE and 26.9% of SA isolates. About 75% of MR isolates were multidrug resistant. SA isolates adhered to host cells more extensively than SE. SA isolates released higher level of LDH than SE.
Adherence abilities were commonly observed in staphylococci associated with conjunctivitis. However, low prevalence of isolates positive for a complete and functional ica locus and low prevalence of strong biofilm producers was detected. SA adhered to a greater extent to eukaryotic cells than SE and were more cytotoxic.

Health checks can detect risk factors and initiate prevention of cardiovascular diseases but there is no consensus on how to communicate the results. The aim of this study was to investigate the preferences of the general population for communicating health check results.
A randomly selected sample of the Swedish population aged 40-70years completed a discrete choice experiment survey that included questions on sociodemographics, lifestyle and health and 15 choice questions consisting of six attributes (written results, notification method, consultation time, waiting time, lifestyle recommendation and cost). Data were analyzed with a latent class analysis (LCA). Relative importance of the attributes and predicted uptake for several scenarios were estimated.
In the analysis, 432 individuals were included (response rate 29.6%). A three-class LCA model best fit the data. Cost was the most important attribute in all classes. Preferences heterogeneity was found for the other attributes; in Class 1, receivingbe able to understand their results.Fanconi anemia (FA) occurs due to genomic instability with predisposition to bone marrow failure, phenotypic abnormalities and cancers. Though mutations in 22 genes leading to DNA repair defect have been identified, the cellular factor such as oxidative stress has also shown to be associated with FA. Nitrosative Stress (NS) is biochemically correlated to many oxidative stress related disorders and the NS as a pathological hallmark in FA has been so far overlooked. We carried out the study first time in Indian patients with FA with an objective to understand the role of NS in the pathogenesis of FA. The study was carried out in 70 FA subjects. The FA subjects were diagnosed by chromosomal breakage analysis. Molecular study was carried out by Next Generation Sequencing and Sanger sequencing. The 3-nitrotyrosine [3-NT] levels were estimated through enzyme-linked immuno-sorbent assay (ELISA) and the nitric oxide synthase genes- NOS1 (c.-420-34221G>A (rs1879417), c.-420-10205C>T (rs499776), c.4286+720G>C (rs81631)) and NOS2 (c.1823C>T (p. Ser608Leu) (rs2297518)) polymorphism were studied by direct sequencing. Chromosomal breakage analysis revealed a high frequency of chromosomal breaks (Mean chromosomal breakage-4.13 ± 1.5 breaks/metaphase) in 70 FA patients as compared to the control. Molecular studies revealed FANCA (58.34%), FANCG (18.34%) and FANCL (16.6%) complementation groups. The 3-nitrotyrosine [3-NT] levels showed to be significantly (p T (p. Ser608Leu) (rs2297518), showed statistically significant (P less then 0.05) association with FA. Elevated level of 3-NT is one of the cause of NS and NOS2 gene polymorphism associated with FA is an important target in the treatment regimen.Coronaviruses are a large family of important pathogens that cause human and animal diseases. At the end of 2019, a pneumonia epidemic caused by a novel coronavirus brought attention to coronaviruses. Exploring the interaction between the virus and its receptor will be helpful in developing preventive vaccines and therapeutic drugs. The coronavirus spike protein (S) plays an important role in both binding to receptors on host cells and fusion of the viral membrane with the host cell membrane. This review introduces the structure and function of the S protein and its receptor, focusing on the binding mode and binding region of both.This article describes the variable appearance of the normal postpartum uterus and reviews complications which can occur in the postpartum period, with particular emphasis on the sonographic findings. Postpartum complications are a common presentation to the emergency department. The majority of these patients present with secondary postpartum hemorrhage. Additional symptoms of pain or clinical findings of pyrexia and leukocytosis confound the clinical scenario and necessitate further evaluation with imaging. Ultrasonography is the mainstay in the initial imaging evaluation of the postpartum patient, with occasional progression to CT, MR, or angiography. We sought to provide a brief review of the literature, with pictorial review of key imaging findings, with a focus on ultrasonography. We provide a pictorial and brief literature review, with case examples from our institution, of key postpartum complications. Ultrasonography is an important component of evaluation in postpartum patients, particularly those with hemorrhage or other complication.
