The kidney risk factors to adverse maternal-fetal outcomes and the effects of pregnancy on pMN process need to be investigated. METHODS We retrospectively screened all the patients with biopsy-proven pMN from 2008 to 2018. Any cases of pregnancy that occurred at the time of pMN diagnosis or during follow-up were included in the study. Clinical and pathological data were collected from all patients at the time of kidney biopsy and their gestational results were recorded. RESULTS Of the 27 pregnancies with gestational time of 35.9 ± 4.5 weeks, 10 adverse maternal-fetal events occurred, including fetal loss (11%), preterm delivery (26%), and severe preeclampsia (15%). The kidney parameters were relatively stable with all preserved kidney function. Time-averaged urinary protein (p less then 0.001) and serum albumin (p less then 0.001), maximum urinary protein (p = 0.001) and minimum serum albumin (p = 0.01) before week 20, anti-phospholipase A2 receptor (PLA2R) positivity (p = 0.03), and no remission during pregnancy (p = 0.004) were risk factors to adverse maternal-fetal outcomes. Time-averaged urinary protein and serum albumin correlated with the birth weight percentile of neonates. CONCLUSIONS Pregnancy in pMN patients showed risks to adverse maternal-fetal events. Heavy proteinuria, especially before week 20 of gestation, severe hypoalbuminemia, positive anti-PLA2R, and no remission were risk factors to worse outcomes. © 2020 S.

However, whether TRPCs play a regulatory role in the development of diabetic retinopathy (DR) has rarely been reported. In the present study, we selected TRPC1, 3, and 6 to determine their roles and mechanism in human retina vascular endothelial cells (HREC) under high glucose (HG) conditions. METHODS HRECs were cultured in vitro under HG, hyper osmosis, and normal conditions. The expression of TRPC1, 3, and 6 in the cells at 24 and 48 h were detected by RT-polymerase chain reaction (PCR), Western blot and cell immunohistochemistry (IHC); In various concentrations, SKF96365 acted on HG cultured HRECs, the expression of vascular endothelial growth factor (VEGF) were detected by the same methods above; and the CCK-8, Transwell, cell scratch assay, and Matrigel assay were used to assess cell proliferation, migration, and lumen formation. RESULTS The RT-PCR, Western blot, and IHC results showed that TRPC1 expression was increased, and TRPC6 mRNA expression was increased under high-glucose conditions. SKF96365 acted on HG cultured HRECs that VEGF expression was significantly decreased. The CCK-8 assay, Transwell assay, cell scratch assay, and Matrigel assay showed that cell proliferation, migration, and lumen formation were downregulated by SKF96365. CONCLUSION HG can induce increased expression of TRPC1 and 6 in HRECs. Inhibition of the TRPC pathway not only can decrease VEGF expression but also can prevent proliferation, migration, and lumen formation of HRECs induced by HG. Inhibition of TRPC channels is expected to become a drug target for DR. © 2020 S. Karger AG, Basel.INTRODUCTION Interaction of OX40 and OX40 ligand (OX40L) is associated with immune activation. OX40-OX40L axis is also suggested to play a role in immunity against several solid malignancies. OBJECTIVE In this study, serum OX40 and OX40L levels in patients with advanced lung adenocarcinoma were assessed and their correlation with survival and clinicopathologic parameters was determined. METHODS Serum samples were collected from patients with advanced lung adenocarcinoma, then OX40 and OX40L were quantified via enzyme-linked immunosorbent assay. Immunohistochemical (IHC) analysis of OX40 and OX40L in resected primary lesions was also performed. The association between OX40 and OX40L levels and clinicopathologic status and patient survival was retrospectively analyzed. RESULTS A total of 56 patients were analyzed. Median serum OX40 and OX40L levels were 156.2 pg/mL and 186.6 pg/mL, respectively. IHC analysis in 5 patients indicated high positivity of OX40 in tumor-infiltrating lymphocytes and of OX40L in tumor cells in mucinous adenocarcinoma. Patients with a high OX40 level (≥152.2 pg/mL) had poorer prognosis than those with a low serum OX40 level (median survival, 7.36 vs. 21.19 months, respectively, p = 0.04). Patients with a high OX40L level (≥207.3 pg/mL) had poorer prognosis than those with a low serum OX40L level (median survival, 7.36 vs. 14.26 months, respectively, p = 0.04). In the subset of patients treated with immune checkpoint inhibitors (ICIs) (n = 12), those with a high OX40L level were found to have longer survival from ICI initiation than those with a low OX40L level (p = 0.023). CONCLUSIONS High OX40 and OX40L levels are associated with poor prognosis and may reflect the immune-exhausted status against lung adenocarcinoma. © 2020 S. Karger AG, Basel.INTRODUCTION Myasthenia gravis (MG) is an autoimmune disease whose period of typical onset is around 20-40 years (i.e., early onset), thus in the peak of working age, or around 60-80 years (i.e., late onset). However, the information on work-related issues and employment status are sparse and not systematically reported. Therefore, we performed a systematic literature review with meta-analysis to address the employment status of MG patients. METHODS We searched for papers reporting employment status on participants with MG published between January 2000 and May 2019. Information on employment was extracted. Random-effects models were used to produce meta-analytic estimates for the proportion of employed patients. Plinabulin RESULTS In total, 1,045 records were retrieved, of which 19 fitted the inclusion criteria. In total, 3,600 participants (average age 47.5, range 35-60) were included in the studies and 1,579 of them were employed. The proportion of employed patients varied from 28 to 82%, with an extreme heterogeneity between studies. Overall, the pooled proportion of workers was 50% (95% CI 41-60%). Subgroup analyses suggested a possible, although not significant, higher proportion of workers among women, younger participants, those with a higher level of education, shorter MG duration, and less frequently thymectomized, whereas a lower proportion was observed among those with generalized, bulbar, and respiratory symptoms. CONCLUSIONS The results of our meta-analysis show that the percentage of employment is considerably low if we take into account that the mean age of MG patients involved in the included studies was around 48 years, thus in peak of working life. Therefore, it is important to understand what kind of influence MG exerts on work dynamics. © 2020 S.

Accelerated venovenous hemofiltration (AVVH) is a modality utilizing higher hemofiltration rates (4-5 L/h) with shorter session durations (8-10 h) to "accelerate" the clearance and volume removal that normally is spread out over a 24-h period in CRRT. We examined AVVH as a transition therapy between CRRT and iHD, with the aim of decreasing time on CRRT and providing a more graduated transition for hemodynamically unstable patients requiring RRT. METHODS Retrospective cohort study describing the clinical outcomes and quality initiative experience of the integration of AVVH into the CRRT program at an academic tertiary care center. Outcomes of interest included mortality, ICU length of stay and readmission rates, and technical characteristics of treatments. RESULTS In total, 97 patients received a total of 298 AVVH treatments (3.1 ± 3.3 treatments per patient). Totally, 271/298 (91%) treatments were completed successfully. During an average treatment time of 9.5 ± 1.6 h with 4.2 ± 0.5 L/h -replacement fluid rate, urea reduction ratio was 23 ± 26% per 10-h treatment, and net ultrafiltration volume was 2.4 ± 1.3 L/treatment. Inpatient mortality was 32%, mean total hospital length of stay was 54 ± 47 days. Sixty-four out of 97 (66%) patients recovered renal function by discharge. Among those who transferred out of the ICU, 7/62 (11%) patients required readmission to the ICU after developing hypotension on iHD. CONCLUSION AVVH can serve as a transition therapy between CRRT and iHD in the ICU and has the potential to decrease total time on CRRT, improve patient mobility, and sustain low ICU readmission rates. Future study is needed to analyze the implications on resource use and cost of this modality. © 2020 S.

OBJECTIVE We investigated drivers of cancer-related immunosuppression across NETs of various sites and grade using multi-parameter immunohistochemistry and targeted transcriptomic profiling. METHODS Tissue microarrays (n=102) were stained for PD-L1 & 2, Indoleamine-deoxygenase-1 (IDO-1) and evaluated in relationship to functional characteristics of tumor-infiltrating T-lymphocytes (TILs) and biomarkers of hypoxia/angiogenesis. PD-L1 expression was tested in circulating tumour cell (CTCs, n=12) to evaluate its relationship with metastatic dissemination. RESULTS PD-L1 expression was highest in lung NETs (n=30, p=0.007), whereas PD-L2 was highest in pNETs (n=53, p less then 0.001) with no correlation with grade or hypoxia/angiogenesis. PD-L1+ NETs (n=26, 25%) had greater CD4+/FOXP3+ and CD8+/PD1+ TILs (p less then 0.001) and necrosis (p=0.02). CD4+/FOXP3+ infiltrate was highest PD-L1/IDO-1 co-expressing tumours (p=0.006). Grade 3 well-differentiated NETs had lower CD4+/FOXP3+ and CD8+/PD1+ TILs density (p less then 0.001) and Nanostring immune-profiling revealed enrichment of macrophage-related transcripts in cases with poorer prognosis. We identified PD-L1(+) CTC subpopulations in 75% of evaluated patients (n=12). CONCLUSIONS PD-L1 expression correlates with T-cell exhaustion independent of tumour hypoxia and is enhanced in a subpopulation of CTCs, suggesting its relevance to the progression of NETs. These findings support a potential therapeutic role for PD-L1 inhibitors in a subset of NETs. © 2020 S.

The modernisation of skin cancer prevention interventions by using social media may enhance their contemporary reach and relevance, especially among the youth. This study aimed to analyse Twitter posts in Australia to establish a baseline of skin cancer and sun-related communication trends. METHODS Tweets posted over the summer of 2018/2019 relating to relevant keywords and hashtags such as "slipslopslap" and "sunscreen" were analysed using quantitative and qualitative methods. The number of tweets, related communication patterns, and possible factors for sudden changes in tweet volume were studied. RESULTS Results showed that Australians are using Twitter to communicate about their sun-related and skin cancer experiences and to share advice and information on this matter. Overall, Australians use Twitter more frequently to talk about sunscreen (number of tweets between December 2018 and February 2019 = 5,842) and/or skin cancer (n = 3,936), but not so often to communicate about other sun-protective behaviours (n = 1,972) or skin cancer prevention campaigns (n = 108).
