MoLCs can be matured, secrete IL-12p70 and TNF-α and stimulate proliferation and cytokine production in allogeneic CD4+ and CD8+ T cells. In regard to vaccine testing, a recently characterized glycomimetic Langerin ligand conjugated to liposomes demonstrated specific and fast internalization into moLCs. Hence, these short-term in vitro-generated moLCs represent an interesting tool to screen LC-based vaccines in the future.Background and aims Heller myotomy (HM) is considered the standard surgical treatment for achalasia patients. However, approximately 10% to 20% of achalasia patients have persistent or recurrent symptoms after HM that require further therapy. Several studies have reported the outcomes of peroral endoscopic myotomy (POEM) in these patients. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of POEM in achalasia patients with prior HM. Methods An electronic literature search was conducted of PubMed, EMBASE, The Cochrane library up to Jan 31, 2020. Studies evaluating the outcomes of POEM in achalasia patients with prior HM were eligible for inclusion. The primary outcomes were the pooled rates of clinical success (defined as post-POEM Eckardt score ≤3), mean change in Eckardt score, lower esophageal sphincter (LES) pressure, and integrated relaxation pressure (IRP). The secondary outcomes were procedure-related adverse events (AEs) and incidence of postoperative gastroesophageal reflux disease (GERD). Results A total of 9 studies with 272 achalasia patients were recruited in this review. POEM was successfully performed in 270 (99.3%) patients after prior HM. Clinical success was achieved in 90.0% (95% CI, 83.1%-96.8%) of patients. Eckardt score, LES pressure and IRP were significantly lowered by 5.14 (95% CI, 4.19-6.09), 12.01 mm Hg (95% CI, 6.74-17.27) and 10.02 mm Hg (95% CI, 4.95-15.09), respectively. The pooled rates of postoperative symptomatic reflux, esophagitis, and abnormal pH monitoring were 36.9% (95% CI, 20.7%-53.1%), 33.0% (95% CI, 9.6%-56.4%), 47.8% (95% CI, 33.4%-62.2%), respectively. Substantial heterogeneity was detected across all outcome measurements. Most of the AEs were self-limiting or managed conservatively. Conclusions POEM is a safe and effective treatment for achalasia patients with prior HM. Further data from prospective, controlled studies with long-term follow-up are needed to confirm these findings.Aims Annually, up to 4% of people with diabetes present with a chronic foot ulcer. Quantitative real-time testing to identify patients at risk for ulceration can guide preventative care. selleckchem Here, we assess whether a non-invasive optical imaging technique, Spatial Frequency Domain Imaging (SFDI), can identify patients at the highest risk for ulceration and predict ulcer onset. Methods We imaged 252 subjects with diabetes at Kaiser Permanente, Southern California. SFDI derived tissue biomarkers of microcirculation were compared between subjects with and without a history of ulceration, and subjects who did or did not develop ulcers after 1 year. Results Feet of subjects at the highest risk (i.e. history of ulceration) had significantly lower hemoglobin in the papillary dermis (HbT1), along with higher oxygenation (StO2) due to poor extraction. These subjects also had more homogeneous hemoglobin spread in the reticular dermis (HbT2) and tissue scattering (related to skin structure). Prediction based on HbT1 and tissue scattering identified new ulcerations and performed with sensitivity/specificity of 68.8%/64.8% and 75.0%/69.1%, respectively. Conclusion These results show that SFDI hemoglobin distribution and oxygenation biomarkers provide a quantitative basis for ulcer risk stratification and ulcer onset prediction.Background Optimal surgical management of limited axillary nodal disease following neoadjuvant chemotherapy (NAC) for breast cancer is evolving. Concerns exist with respect to leaving residual disease in the axilla when omitting axillary lymph node dissection (ALND) in this setting. We sought to determine whether extent of nodal surgery altered patterns of failure and patient outcomes. Patients and methods We identified 70 patients with breast cancer who were confirmed cN0 after NAC yet had residual nodal disease (ypN1) on sentinel lymph node biopsy (SLNB). Twenty-eight patients underwent SLNB alone and 42 underwent SLNB+completion (c)ALND in a non-randomized fashion. Most (n = 65) patients underwent adjuvant regional nodal irradiation (RNI). Detailed patterns of failure data were obtained for each patient. Results The median follow-up was 43.5 months. There were 30 (43%) recurrences. Of these, 5 were isolated locoregional failures, and 24 were distant failures. There were no significant differences in local (P = .13), regional (P = .62), or distant (P = .47) failure between patients who underwent SLNB alone versus SLNB+cALND. Seventeen (24%) patients died. Overall survival was similar in both groups with median overall survival not reached for those who underwent SLNB and 109 months for those who underwent SLNB+cALND (P = .45). Conclusions There were no differences in patterns of recurrence among patients with 1 to 3 involved lymph nodes after NAC who underwent SLNB alone versus SLNB+cALND in the setting of RNI. We await the results of ongoing, prospective clinical trials to confirm the relative merits of RNI in lieu of cALND in these patients.Age-related macular degeneration (AMD) and proliferative diabetic retinopathy (DR) are two of the most common and severe causes of vision loss in the population. Both conditions are associated with excessive levels of vascular endothelial growth factor (VEGF) in the eye which results in an increase in the formation of new blood vessels through a process called neovascularisation. As such, anti-VEGF therapies are currently utilised as a treatment for patients with AMD however they are associated with painful administration of injections and potential degeneration of healthy endothelium. There is therefore growing interest in alternate treatment options to reduce neovascularisation in the eye. The use of carotenoids, lutein (L) and zeaxanthin (Z), has been shown to improve vision loss parameters in patients with AMD, however the underlying mechanisms are not well-understood. We studied the impact of these compounds on neovascularisation processes using an in vitro cell model of the retinal microvascular endothelium.
