The independent role of solar radiation in the differential melanogenesis between melasma and adjacent skin is unknown.

To assess the melanogenic responses of skin with facial melasma and of the adjacent skin to UVB, UVA, and visible light, in an ex vivo model.

This was a quasi-experimental study involving 22 patients with melasma. Facial melasma and adjacent skin samples were collected and stored in DMEM medium, at room temperature. One fragment was placed under the protection from light, while another was exposed to UVB, UVA, and visible light (blue-violet component) 166 mJ/cm

, 1.524 J/cm

, and 40 J/cm

, respectively. Subsequently, all samples were kept for 72 hours in a dark environment and stained by Fontana-Masson to assess basal layer pigmentation, dendrites, and melanin granulation.

Effective melanogenesis was observed in the basal layer in melasma and in the normal adjacent skin after all irradiations (p < 0.01), with the following median increment UVB (4.7% vs. 8.5%), UVA (9.5% vs. 9.9%), and visible light (6.8% vs. 11.7%), with no significant difference between anatomical sites. An increase in melanin granulation (coarser melanosomes) was observed only after irradiation with UVA and only in the skin with melasma (p = 0.05). An increase in the melanocyte dendrite count induced by UVB radiation was observed in both anatomical sites (p ≤ 0.05).

Use of an ex vivo model, with independent irradiation regimes for UVB, UVA, and visible light.

Melanogenesis induced by UVB, UVA, and visible light was observed both in melasma and in the adjacent skin. The morphological patterns suggest that different irradiations promote individualized responses on the skin with melasma.

Inflammatory markers have prognostic value in various tumors due to the role of inflammatory phenomena at different stages of tumor development. The aim of this study is to demonstrate the prognostic value of these markers, as well as other clinical and analytical variables in patients with metastatic castration-resistant prostate cancer (mCRPC).

Prospective cohort study carried out on 80 patients diagnosed with mCRPC. Clinical and analytical data were collected, and the following inflammatory markers were estimated Absolute Neutrophil Count (ANC), Neutrophil-Lymphocyte Ratio (NLR), Total Platelet Count (TPC), Platelet-Lymphocyte Ratio (PLR), Lymphocyte-Monocyte Ratio (LMR) and Systemic Inflammation Index (SII). The values of albumin, hemoglobin (Hb), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were also determined.

Patients with ANC>7500, NLR>3, PLR>150, LMR>3 and/or SII>535,000, presented significantly lower median survival time than the remaining patients, and TPC was the only marker which did not show a significant association. Moreover, NLR, PLR and SII were inversely correlated with survival time. Patients with hypoalbuminemia, anemia, and elevated LDH values had significantly lower median survival time. Albumin and hemoglobin were directly correlated to overall survival time. Selleck Degrasyn The need for analgesia was also associated with shorter survival.

The values of certain inflammatory markers are associated with shorter survival time in patients with mCRPC, and their use in clinical practice can be considered to evaluate the prognosis and estimate survival.

In this retrospective study, we aimed to evaluate lymph node (LN) density in retroperitoneal lymph node dissection (RPLND) to analyze whether residual mass after chemotherapy might behave as predicting factor for recurrence in patients with germ cell testicular cancer (GCTC).

The data of 185 patients that were operated between 12/2004 and 02/2017 because of GCTC were reviewed retrospectively. LN density was calculated. The patients were compared statistically in terms of demographic features, tumor characteristics, serum tumor marker levels, treatment strategies, and pathological results according to GCTC subtypes. Correlation analysis was performed to determine the parameters related to recurrent disease.

The median follow-up was 79 (31-179) months and the median age of the patients was 23 (16-71). The median tumor size was 4 (1-18) cm. Five (2.7%) patients had metastatic disease at initial diagnosis. Seminoma, non-seminomatous-GCT and mix type-GCTC was detected in 62 (33.5%), 60 (32.4%) and 63 (34.1%) patients, respectively. Following inguinal orchiectomy, 48 (25.9%) patients underwent follow-up, 126 (68.1%) patients underwent chemotherapy and 11 (5.9%) patients underwent radiotherapy. A total of 21 (11.4%) patients underwent post-chemotherapy RPLND. Early and late recurrence was seen in 3 (1.6%) and 2 (1.1%) of the patients, respectively. A mild to moderate, negative, but significant correlation was found between the recurrence and the number of LNs containing metastatic deposits and LN density (r= -0.490, P=.024 and r= -0.450, P=.041, respectively).

There was a negative correlation between the number of LNs containing metastatic deposits and LN density and recurrent disease.

Bladder cancer is the second most common urological cancer in the world, but there are limited data on the quality of bladder cancer information on social networks. Our objective was to characterize the quality of information and presence of misinformation about bladder cancer on YouTube, the most commonly used social media platform. We reviewed the first 150 YouTube videos about "bladder cancer" using two validated instruments for consumer health information and assessed the videos for the presence of misinformation. The videos had a median of 2288 views (range, 14-511 342), but the overall quality of information was moderate to poor in 67%, based on scores of 1-3 out of 5 on the validated DISCERN instrument. A moderate to high amount of misinformation was present in 21% of videos and reached 1 289 314 viewers. Commercial bias was apparent in 17% of videos, which reached 324 287 viewers. From a networking perspective, comments sections in the videos were sometimes used to request medical advice (20%), provide medical advice to others (9%), or give support (19%). In conclusion, YouTube is a widely used source of information and advice about bladder cancer, but much of the content is of poor quality. PATIENT SUMMARY A large quantity of content about bladder cancer is available on YouTube. Unfortunately, much of the content is of moderate to poor quality and presents a risk of exposure to misinformation.

There is no universally accepted definition for prostate-specific antigen (PSA) progression. However, changes in PSA in patients with castration-resistant prostate cancer (CRPC) are used to inform treatment decisions.

To determine whether the Prostate Cancer Working Group 2 (PCWG2) definition of PSA progression is adequate to predict radiographic or clinical progression in enzalutamide-treated men with nonmetastatic CRPC (nmCRPC).

A post hoc, retrospective analysis of men with nmCRPC from PROSPER (NCT02003924) was performed.

Continued androgen deprivation therapy; patients randomized 21 to enzalutamide 160 mg/d or placebo.

Metastasis-free survival (MFS) in men with and without PSA progression, defined by PCWG2, and PSA at the time of radiographic progression were assessed.

As of June 28, 2017, in enzalutamide-treated patients, the risk of metastasis or death was increased significantly in those with PSA progression versus those without (hazard ratio [HR] 3.99; 95% confidence interval [CI], 2.95-5.A) in enzalutamide-treated men with nonmetastatic castration-resistant prostate cancer who no longer respond to testosterone-lowering treatment. We found that even very small changes in PSA while on treatment could be an early indication of disease progression and should trigger closer monitoring.

This study examined the prevalence of hypertension in adolescents, with the aim of determining a link between blood pressure and body composition measurements.

This cross-sectional study included adolescents aged 14-19 years attending schools. Their body mass index (BMI) and waist circumference (WC) measurements were recorded. Blood pressure (BP) was taken three or more times, with an average systolic BP and/or diastolic BP ≥ the 95th percentile was regarded as hypertension.

The prevalence rates of pre-hypertension and hypertension were 11.2% and 14.8%, respectively. Obese and overweight adolescents had a higher prevalence of hypertension compared with those of normal weight (41.6% and 15.5% versus 6.2%, respectively). Following adjustment for BMI status and WC, significant correlations were observed between overweight/obesity and hypertension. After adjusting for BMI status and WC, abdominal obesity was not associated with hypertension.

A comparatively high prevalence of hypertension was found among the adolescents. Obesity and overweight were highly correlated with hypertension.

School nurses and doctors must describe and address high or raised blood pressure levels in children and adolescents. Because of the high prevalence of hypertension in the obese and overweight adolescents, this study emphasizes the need for the early prevention and control of obesity and hypertension among children.

Muscle invasive bladder cancer (MIBC) is commonly treated with radical cystectomy. Patients who require radical cystectomy are often frail, unwell, have multiple comorbidities, and can experience unmet supportive care needs. Due to these complexities, patients requiring radical cystectomy are often considered high risk for anesthetics, and therefore improving their physical and psychological well-being is crucial prior to radical surgery. Prehabilitation is the practice of enhancing a patient's functional and psychological capacity before surgery, with the aim of improving postoperative outcomes. This narrative review aims to identify and evaluate the role of physical exercise, nutritional intervention, and person-centered holistic approaches to prehabilitation in people affected by MIBC treated by radical cystectomy.

Electronic databases including CINAHL, MEDLINE, PsychINFO, Scopus, and grey literature were searched using Google scholar until June 2020.

Evidence to support specific prehabilitation clinical recommendations in people affected by MIBC is emerging.
