7% of subjects (81/107). Similarly, significant decrease in mean CLDEQ-8 scores between baseline and 2-week follow-up occurred in all subject groups, indicating a decrease in the prevalence of dryness and discomfort symptoms. CLDEQ-8 score improved clinically (≥3-point reduction) among 82.2% of subjects (88/107). A majority of subjects (57.0%) became asymptomatic (CLDEQ-8 score≤11 points) after 2weeks of bilateral wear.

According to the Alzheimer's Society there are over 850,000 people with dementia in the UK, costing the UK £26 billion in 2013. Therefore, research into treatment of those conditions is vital. Research into the cerebral endothelial glycocalyx (CeGC) could offer effective treatments. The CeGC, consisting of proteoglycans, glycoproteins and glycolipids, is a dynamic structure covering the luminal side oftheendothelial cells of capillaries throughout the body. The CeGC is thicker in cerebral micro vessels, suggesting specialisation for its function as part of the blood-brain barrier (BBB). Recent research evidences that the CeGC is vital in protecting fragile parenchymal tissue and effective functioning of the BBB, as one particularly important CeGC function is to act as a protective barrier and permeability regulator. CeGC degradation is one of the factors which can lead to an increase in BBB permeability. It occurs naturally in aging, nevertheless, premature degradationhas beenevidencedin multipleconditions linked to cognitive impairment, such as inflammation,brain edema, cerebral malaria, Alzheimer's and recently Covid-19. Increasing knowledge of the mechanisms of CeGC damage has led to research into preventative techniques showing that CeGC is a possible diagnostic marker and a therapeutic target. However, the evidence is relatively new, inconsistent and demonstrated mainly in experimental models. This review evaluates the current knowledge of the CeGC, its structure, functions, damage and repair mechanisms and the impact of its degeneration on cognitive impairment in multiple conditions, highlighting the CeGC as a possible diagnostic marker and a potential target for therapeutic treatment.
This study reviewed the literature on the laparoscopic management of cloaca.

A Medline and Embase search was performed for "laparoscopy" and "cloaca." Articles for which full-text in English was not available, duplicate articles, and review articles were excluded. Demographic characteristics, duration of follow-up, length of common channel, postoperative complications, and functional outcomes were analyzed.

The database search retrieved 81 articles after excluding unrelated articles and identified new articles through cross-referencing 14 articles (72 patients) for this review. The rectal pouch was situated below the pubococcygeal (PC) line in three patients. In all other patients, the rectum was located above the PC line. Only the rectal component of the malformation was repaired laparoscopically in 80% (58/72). Fourteen patients underwent laparoscopic mobilization of the rectum and urogenital component. The length of the common channel was more than 3cm in all these fourteen patients. The most common ies propose that the urogenital separation technique be preferred over urogenital mobilization in patients with the short urethra. Nonetheless, we still don't have long-term comparative data to demonstrate that the functional outcomes are better with this new algorithm. We conclude that the persistent cloaca needs an individualized approach, and laparoscopy can be utilized to mobilize the high rectum and is also helpful for the urogenital separation in patients with common channel length >3cm. However, at present, there is no conclusive evidence to support that laparoscopic repair has a better functional outcome than the open approach.

Vitamin D plays a fundamental role in calcium homeostasis and bone metabolism. It mainly comes from cutaneous synthesis through the action of sunlight. Therefore, variations in exposure to this radiation modify serum levels. We studied two different analytes of vitamin D in the healthy Spanish population and the influence of seasonality, climate, and latitude on its levels.

This work is a cross-sectional, descriptive study. A total of 206 blood donors from Burgos and Valencia between 18-60 years of age were recruited during March-April and October-November 2018. Total and free serum 25-hydroxycholecalciferol (25(OH)D) were analyzed.

After summer, total and free serum 25(OH)D medium levels were 24.31 ± 5.25 ng/mL and 5.01 ± 1.25 pg/mL in Burgos and 25.99 ± 6.87 ng/mL and 8.97 ± 2.82 pg/mL in Valencia. After winter, they were 17.66 ± 5.04 ng/mL and 4.08 ± 0.66 ng/mL in Burgos and 21.38 ± 3.77 ng/mL and 7.23 ± 2.44 ng/mL in Valencia. The seasonal changes were statistically significant for both components studied both in the sample as a whole and in the separate populations. The differences found between the two populations in total and free 25(OH)D levels were statistically significant except for total 25(OH)D after summer (24.07 ng/mL vs. 26.03 ng/mL; p = .408). Latitude was also shown to be a factor that influences concentrations of both analytes in summer and winter.

Our study shows lower vitamin D levels than expected for a healthy Spanish population. Seasonality, climate, and latitude were demonstrated to influence total and free 25(OH)D levels.

Guidelines do not recommend FDG-PET CT for the staging of MIBC as a standard. The objectives of the study are to assess the accuracy of the FDG-PET CT for LN staging and to determine the rate of treatment modification according to FDG-PET CT results in MIBC.

From January 2005 to December 2017, we carried out a retrospective analysis of patients with MIBC who had a FDG-PET CT for staging in two expert centres in Bordeaux, France, and analyzed its clinical value in this setting. Nodal and metastatic staging on CT scan (CT) and FDG-PET CT were done independently.

Accuracy of LN staging from CT and FDG-PET CT at initial diagnosis was analyzed in 85 patients (including 70 patients treated with neoadjuvant chemotherapy (NAC)) and compared to pathological examination of resected LN. Sensitivity of FDG-PET CT was better than CT (80.8% versus 26.9%) but the specificity was low (54.2% vs. 83.1%). The Youden index was better for FDG-PET CT (0.35; 0.1 for CT) and FDG-PET CT appeared to be more accurate for determining LN staging of MIBC. FDG-PET CT findings enabled a treatment decision modification in 34/130 patients (26.1%) a therapeutic intensification (9.2%), including surgery not previously planned and/or modified fields of radiotherapy; or a de-escalation (16.9%), mostly avoiding surgery.

FDG-PET CT was more sensitive for detection of LN involvement at initial diagnosis of MIBC than CT alone. In our study, treatment decisions were modified, according to FDG-PET CT results, in almost a quarter of patients.

Sarcomatoid urothelial carcinoma (SUC) is a rare and aggressive variant of bladder cancer with limited data regarding epidemiology and survival. In this study, we explored clinicopathologic factors and oncologic outcomes of patients with SUC derived from Survival, Epidemiology and End Results (SEER) database, in comparison to conventional UC (CUC).

SEER database was searched for patients with invasive (≥T1) SUC or CUC using the topography codes C67.0 to C67.9 for bladder cancer and the morphologic codes 8120/8122 for CUC/SUC respectively. Demographic/clinicopathologic/treatment/survival data were extracted. Disease-specific survival (DSS) was estimated with the Kaplan-Meier method. Chi-squared tests were used for comparative analysis and Cox proportional hazards model for identifying clinical covariates associated with DSS.

A total of 569 patients with SUC and 37,740 with CUC were identified. Overall, there was a male predominant population in both cohorts, although a higher proportion of women were noted in the SUC cohort (32 vs. 25%). Raf inhibitor Patients with SUC had significantly higher incidence of non-bladder confined disease (T3/4, 37% vs. 22%) and nodal invasion (18% vs. 12%) in comparison to those with CUC (all P < .05). Median DSS was 16 months (95% CI 12.4-19.6) in the SUC vs. 82 months (95% CI; 75.9-88.1) in the CUC cohort. Presence of SUC histology was independently associated with shorter DSS in the multivariate analysis, when adjusted for other significant clinicopathologic factors.

SUC was associated with advanced stage and shorter DSS compared to CUC. Further studies are needed to better understand biological underpinnings behind its aggressive behavior and the role of novel systemic treatments.

Genetic alterations are increasingly being recognized to play an important role in both diagnosis and prognosis of MDS. In general, MDS patients with SF3B1 mutations (MT) are known to have favorable outcomes whereas those with TP53 mutations have dismal survivals. However, it is unclear if the impact of these mutations applies to all subtypes of MDS including del(5q) which is known for its response to lenalidomide and better prognosis.

We retrospectively reviewed 132 del(5q) MDS patients who were treated at the Moffitt Cancer Center (2001-2019).

Among patients who received lenalidomide (n=98), 50%, 42.9%, and 7.1% achieved hematologic improvement or better, no response, and disease progression/death with a median overall survival (mOS) of 93.2, 72.4, and 25.6 months, respectively (P < .0001). The mOS was 73.3 months but only 25.6 months after patients stopped lenalidomide. TP53 was the most common mutation accounting for 23.8% of the patients. Of the 63 patients with molecular data available, 23.8% harbored TP53 MT and 10% with SF3B1 MT. TP53 status did not impact OS (MT 86.4 vs. wild-type (WT) 73.3 months; P=.72) but those with SF3B1 mutations had a significantly shorter mOS compared to WT (23.9 vs. 83.5 months; P=.001). Multivariate analysis confirmed lenalidomide response and SF3B1 mutations are independently associated with outcomes.

Our findings indicate many del(5q) MDS patients will benefit from lenalidomide but survival after its failure is limited. Mutations known to have prognostic impact in MDS at large may not have the same implications in the del(5q) subset.
