AMP cell treatment increased retinal ganglion cell (RGC) survival and decreased optic nerve inflammation, with variable improvement in optic nerve demyelination and spinal cord inflammation and demyelination. Results show systemic AMP cell administration inhibits RGC loss and visual dysfunction similar to previously demonstrated effects of intranasally delivered ST266. Importantly, AMP cells also promote neuroprotective effects in EAE spinal cords, marked by reduced paralysis. Protective effects of systemically administered AMP cells suggest they may serve as a potential novel treatment for multiple sclerosis.
Melanoma and the immune system are intimately related. However, the association of immunosuppressive medications (ISMs) with survival in melanoma is not well understood. The study evaluated this at a population level.

A cohort of patients with a diagnosis of invasive cutaneous melanoma (2007-2015) was identified from the Ontario Cancer Registry and linked to identify demographics, stage at diagnosis, prescription of immunosuppressive medications (both before and after diagnosis), and outcomes. The demographics of patients with and without prescriptions for ISM were compared. Patients eligible for Ontario's Drug Benefit Plan were included to ensure accurate prescription data. The primary outcome was overall survival. Cox Proportional Hazards Regression models identified factors associated with mortality, including use of ISM as a time-varying covariate.

Of the 4954 patients with a diagnosis of cutaneous melanoma, 1601 had a prescription for ISM. The median age of the patients was 74years. Selleck BLU9931 Overall, 58.4% of the patients were men (60.5% of those without ISM and 54% of those using ISM; p < 0.001). The use of oral immunosuppression was associated with an increased hazard of death (hazard ratio, 5.84; 95% confidence interval, 5.11-6.67; p < 0.0001) when control was used for age, disease stage at diagnosis, anatomic site, comorbidity, and treatment. Other factors associated with death were increasing age, male sex, increased disease stage, truncal location of primary melanoma, and inadequate treatment. In sensitivity analysiswith steroid-onlyISM use excluded, survival did not differ significantly (p = 0.355).

The use of immunosuppressive steroids for melanoma is associated with worse overall survival. Use of steroids should be limited when possible.

Previous studies evaluating the association of lymph node (LN) yield and survival presented conflicting results and many may be influenced by confounding and stage migration.

This study aimed to evaluate whether the quality indicator 'retrieval of at least 15 LNs' is associated with better long-term survival and more accurate pathological staging in patients with esophageal cancer treated with neoadjuvant chemoradiotherapy and resection.

Data of esophageal cancer patients who underwent neoadjuvant chemoradiotherapy and surgery between 2011 and 2016 were retrieved from the Dutch Upper Gastrointestinal Cancer Audit. Patients with < 15 and ≥ 15 LNs were compared after propensity score matching based on patient and tumor characteristics. The primary endpoint was 3-year survival. To evaluate the effect of LN yield on the accuracy of pathological staging, pathological N stage was evaluated and 3-year survival was analyzed in a subgroup of patients with node-negative disease.

In 2260 of 3281 patients (67%) ≥ 15 LNs were retrieved. In total, 992 patients with ≥ 15 LNs were matched to 992 patients with < 15 LNs. The 3-year survival did not differ between the two groups (57% vs. 54%; p = 0.28). pN+ was scored in 41% of patients with ≥ 15 LNs versus 35% of patients with < 15 LNs. For node-negative patients, the 3-year survival was significantly better for patients with ≥ 15 LNs (69% vs. 61%, p = 0.01).

n this propensity score-matched cohort, 3-year survival was comparable for patients with ≥ 15 LNs, although increasing nodal yield was associated with more accurate staging. In node-negative patients, 3-year survival was higher for patients with ≥ 15 LNs.

Treatment for obstructing colon cancer (OCC) is controversial because the outcome of acute resection is less favorable than for patients without obstruction. Few studies have investigated curable right-sided OCC, and patients with OCC usually undergo acute resection. This study aimed to better understand the outcome and best management of potentially curable right-sided OCC.

A systematic review of studies was performed with a focus on differences in mortality and morbidity between emergency resection and staged treatment for patients with potentially curable right-sided OCC. In March 2019, the study searched Embase, Medline, Web of Science, Cochrane, and Google scholar databases according to PRISMA guidelines using search terms related to "colon tumour," "stenosis or obstruction and surgery," and "decompression or stents." All English-language studies reporting emergency or staged treatment for potentially curable right-sided OCC were included in the review. Emergency resection and staged resection were compared for mortality, morbidity, complications, and survival.

Nine studies were found to be eligible and comprised 600 patients treated with curative intent for their right-sided OCC by emergency resection or staged resection. The mean overall complication rate was 42% (range 19-54%) after emergency resection, and 30% (range 7-44%) after staged treatment. The average mortality rate was 7.2% (range 0-14.5%) after emergency resection and 1.2% (range 0-6.3%) after staged treatment. The 5-year disease-free and overall survival rates were comparable for the two treatments.

The patients who received staged treatment for right-sided OCC had lower mortality rates, fewer complications, and fewer anastomotic leaks and stoma creations than the patients who had emergency resection.

Phase 3 randomized clinical trials have been designed to compare secondary cytoreductive surgery followed by systemic therapy with systemic therapy alone for management of patients with recurrent ovarian cancer. This study aimed to compare differences in clinical outcomes between these two treatment approaches.

The PRISMA statement was applied. Only phase 3 randomized clinical trials were included in the final analysis.

Three randomized clinical trials (n = 1250 patients) were identified. Secondary cytoreductive surgery was associated with significantly better progression-free survival (PFS) improvement than systemic therapy alone (hazard ratio [HR], 95% CI, 0.61-0.78; p < 0.001). The PFS benefit was greater for the complete resection subpopulation (HR, 0.56; 95% CI, 0.48-0.66; p < 0.001). The HR of overall survival (OS) was similar between the groups (HR, 0.93; 95% CI, 0.78-1.10; p = 0.37), but it was 0.73 (95% CI, 0.59-0.91) in favor of the complete resection subpopulation.

This meta-analysis showed secondary cytoreductive surgery as superior to systemic therapy alone in terms of PFS. The PFS and OS benefits were particularly observed for complete surgical resection. The impact on OS in the general population remains to be proven.

Oocyte quality and reproductive outcome are negatively affected by advanced maternal age, ovarian stimulation and method of oocyte maturation during assisted reproduction; however, the mechanisms responsible for these associations are not fully understood. The aim of this study was to compare the effects of ageing, ovarian stimulation and in-vitro maturation on the relative levels of transcript abundance of genes associated with DNA repair during the transition of germinal vesicle (GV) to metaphase II (MII) stages of oocyte development.

The relative levels of transcript abundance of 90 DNA repair-associated genes was compared in GV-stage and MII-stage oocytes from unstimulated and hormone-stimulated ovaries from young (5-8-week-old) and old (42-45-week-old) C57BL6 mice. Ovarian stimulation was conducted using pregnant mare serum gonadotropin (PMSG) or anti-inhibin serum (AIS). DNA damage response was quantified by immunolabeling of the phosphorylated histone variant H2AX (γH2AX).

The relative transcript abundance in DNA repair genes was significantly lower in MII oocytes compared to GV oocytes in young unstimulated and PMSG stimulated but was higher in AIS-stimulated mice. Interestingly, an increase in the relative level of transcript abundance of DNA repair genes was observed in MII oocytes from older mice in unstimulated, PMSG-stimulated and AIS-stimulated mice. Decreased γH2AX levels were found in both GV oocytes (82.9%) and MII oocytes (37.5%) during ageing in both ovarian stimulation types used (PMSG/AIS; p < 0.05).

In conclusion, DNA repair relative levels of transcript abundance are altered by maternal age and the method of ovarian stimulation during the GV-MII transition in oocytes.

Several factors place resettled refugees at elevated risk for exposure to persons with COVID-19 or increased severity of COVID-19 being more likely to experience poverty and live in crowded housing, being employed in less protected, service-sector jobs, experiencing language and health care access barriers, and having higher rates of co-morbidities. In preparing for and managing COVID-19, resettled refugees encounter similar barriers to those of other racial or ethnic minority populations, which may then be exacerbated by unique barriers experienced from being a refugee. Key recommendations for resettlement and healthcare providers include analyzing sociodemographic data about refugee patients, documenting and resolving barriers faced by refugees, developing refugee-specific outreach plans, using culturally and linguistically appropriate resources, ensuring medical interpretation availability, and leveraging virtual platforms along with nontraditional community partners to disseminate COVID-19 messaging.
