Aim Evaluation of suitable pharmacokinetic properties is critical for successful development of IgG-based biotherapeutics. The prolonged half-lives of IgGs depend on the intracellular trafficking function of neonatal Fc receptor, which rescues internalized IgGs from lysosomal degradation and recycles them back to circulation. Results Here, we developed a novel cell-based assay to quantify recycling of monoclonal antibodies in a transwell culture system that uses a cell line that stably expresses human neonatal Fc receptor. We tested seven therapeutic antibodies and showed that the recycling output of the assay strongly correlated with the clearance in humans. Conclusion This recycling assay has potential application as a pharmacokinetic prescreening tool to facilitate development and selection of IgG-based candidate therapeutic monoclonal antibodies.

People in disadvantaged areas are more likely to have an avoidable emergency hospital admission. Socio-economic inequality in avoidable emergency hospital admissions is monitored in England. Our aim was to inform local health care purchasing and planning by identifying recent health care system changes (or other factors), as reported by local health system leaders, that might explain narrowing or widening trends.

Case studies were undertaken in one pilot and at five geographically distinct local health care systems (Clinical Commissioning Groups, CCGs), identified as having consistently increasing or decreasing inequality. see more Local settings were explored through discussions with CCG officials and stakeholders to identify potential local determinants. Data were analysed using a realist evaluation approach to generate context-mechanism-outcome (CMO) configurations.

Of the five geographically distinct CCGs, two had narrowing inequality, two widening, and one narrowing inequality, which widened during the projlity indicators. They are unlikely to find simple, cheap interventions to reduce inequalities in avoidable emergency admissions. Rather, long-term multifaceted interventions are required that embed inequality considerations into mainstream decision making.

We did not find any bespoke initiatives that explained the inequality trends. The trends were more likely due to an interplay of multiple health care and wider system factors. Local decision makers need greater awareness, understanding and support to interpret, use and act upon inequality indicators. They are unlikely to find simple, cheap interventions to reduce inequalities in avoidable emergency admissions. Rather, long-term multifaceted interventions are required that embed inequality considerations into mainstream decision making.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiologic agent of COVID-19. Testing for SARS-CoV-2 infection is a critical element of the public health response to COVID-19. Point-of-care (POC) tests can drive patient management decisions for infectious diseases, including COVID-19. POC tests are available for the diagnosis of SARS-CoV-2 infections and include those that detect SARS-CoV-2 antigens as well as amplified RNA sequences. We provide a review of SARS-CoV-2 POC tests including their performance, settings for which they might be used, their impact and future directions. Further optimization and validation, new technologies as well as studies to determine clinical and epidemiological impact of SARS-CoV-2 POC tests are needed.Aim Lymphocyte-to-monocyte ratio (LMR) predicts overall survival (OS) in patients with colorectal cancer. We explored LMR in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Materials & methods We identified all patients undergoing CRS/HIPEC for colorectal or appendiceal adenocarcinoma at our institution. We analyzed LMR's relationship with clinicopathologic variables with Kaplan-Meier log-rank survival analyses and multivariable Cox regression models with 5-year OS. Results Two hundred and sixteen patients underwent CRS/HIPEC. Five-year OS for low LMR (≤3.71) was 35.2 versus 60.4% for elevated LMR (hazard ratio [HR] 2.0; 95% CI 1.1-3.5; p = 0.02). On multivariable Cox-regression, elevated LMR was significantly associated with OS (p ≤ 0.05). Conclusion LMR is an independent predictor of OS in patients undergoing CRS/HIPEC for colorectal and appendiceal adenocarcinoma.

The Medyria TrackCath Catheter (MedTCC) is an innovative, thermal convection-based blood flow velocity (BFV) tracking catheter that may be used during complex aortic endovascular procedures for identification and catheterization of target orifices. The ACCESS Trial analyzes the safety and performance of the MedTCC for targeted vessel catheterization to generally evaluate the feasibility of thermal convection-based BFV.

We performed a first-in-human, proof-of-concept, prospective single-arm multicenter clinical trial between March 2018 and February 2019 in patients who underwent endovascular aortic procedures at 4 high-volume centers. During these procedures, the MedTCC was advanced over a guidewire through the femoral access. The D-shape was enfolded in the reno-visceral part of the aorta and target orifices were identified and catheterized with a guidewire via the side port of the MedTCC through BFV tracking. BFV measurements were performed at baseline (Baseline-BFV), alignment to the orifice (Orifice-BFet orifice identification and catheterization. The use of MedTCC is safe and generates short fluoroscopy time and low contrast agent use, which in turn might facilitate complex endovascular procedures.

The ACCESS Trial suggests that BFV measurement allows for reliable target orifice identification and catheterization. The use of MedTCC is safe and generates short fluoroscopy time and low contrast agent use, which in turn might facilitate complex endovascular procedures.Aim Circular RNA can serve as a biomarker for early diagnosis of pancreatic cancer. Materials & methods Analyzed the expression of various differentially expressed circular RNAs in the pancreatic cancer tissues by gene chip and identified the expression of hsa_circ_0013587 in pancreatic cancer cells, tissues and plasma by quantitative reverse transcription PCR (qRT-PCR). Results Hsa_circ_0013587 was highly expressed in the pancreatic cancer tissues, cell lines and plasma samples from patients with pancreatic cancer. Notably, hsa_circ_0013587 was upregulated in pancreatic cancer patients with later clinical stages III-IV as compared with those detected in early clinical stages I-II. Conclusion A high expression of hsa_circ_0013587 may serve as a novel diagnostic and therapeutic biomarker for pancreatic cancer.Aim Nondiabetic patients have been studied to determine whether modest elevations in plasma mannose levels may be associated with a greater incidence of coronary artery disease (CAD). Materials & methods The plasma mannose, lipids (triglyceride, low-density lipoprotein, high-density lipoprotein, very low-density lipoprotein) and lactate dehydrogenase levels were successfully evaluated with respect to subsequent CAD using records of 120 nondiabetic patients and 120 healthy volunteers. CAD was identified from myocardial infarction and new diagnoses of angina. Results Of 120 patients studied, the plasma mannose, triglyceride, lactate dehydrogenase and very low-density lipoprotein levels of patients were significantly higher than control groups. Conclusion Our findings showed that elevated baseline mannose in plasma was associated with a progressive risk of CAD with time.Aim To detect predictive value of preconception or early pregnancy sex hormone-binding globulin (SHBG) for subsequent gestational diabetes mellitus (GDM). Materials & methods We searched Embase, Medline, PubMed, Web of Science and Cochrane library up to January 2020. Studies assessing diagnostic performance of SHBG for GDM diagnosed by well-defined diagnostic criteria using oral glucose tolerance test. Results Totally seven studies with 1947 women were included and 247 were diagnosed as GDM. SHBG had a combined diagnostic odds ratio of 6.68 (95% CI 4.58-9.74), sensitivity of 0.70 (95% CI 0.51-0.84), specificity of 0.74 (95% CI 0.52-0.88), positive likelihood ratio of 2.49 (95% CI 1.73-3.57) and negative likelihood ratio of 0.37 (95% CI 0.23-0.61). The area under the summary receiver operating characteristic curve was 0.78 (95% CI 0.74-0.82). Conclusion SHBG had a predictive value for GDM and might improve GDM screening. However, heterogeneity between studies warrants more research into this topic.Aim Chronic postsurgical pain (CPSP) is a common complication of surgery. This study was conducted to evaluate the efficacy and safety of paresthesia-free, 10-kHz spinal cord stimulation (SCS) as a treatment for CPSP. Patients & methods Subjects in this prospective, single-arm study had an average pain intensity of ≥5 cm on a 10-cm visual analog scale. The subjects who had pain relief of ≥50% (response) with temporary trial stimulation were permanently implanted with 10-kHz SCS and assessed for 1 year. Results At 12 months, 94% of subjects were responders to 10-kHz SCS, and 88% had pain remission (visual analog scale ≤2.5 cm). Conclusion The pain relief was durable in CPSP subjects and the safety profile of 10-kHz SCS was as expected.

This study compares morphology of the proximal capitate and the medial femoral trochlear surfaces to the proximal lunate using three-dimensional geometric morphometric analysis. Virtual articular surfaces were extracted from MRI studies of ten healthy volunteers. Distances between corresponding points on the proximal lunate and proximal capitate or medial femoral trochlear surfaces were measured. In seven subjects, mean inter-surface distance for the medial femoral trochlea-proximal lunate pair was significantly lower than the proximal capitate-proximal lunate pairing. In three subjects, mean proximal capitate-proximal lunate distance was significantly lower. We conclude that the medial femoral trochlear flap was anatomically closer to the shape of the proximal lunate in the majority of the examined subjects. However, we found that in three out of ten cases, the proximal capitate was a better match.

Tunneled hemodialysis catheter-related bloodstream infection is a major cause of morbidity and mortality in end-stage renal disease patients. Side holes positioned near the tip of catheters have been linked to formation of thrombi, which, in turn, have been implicated in predisposition to infection. In addition, side holes allow spillage of catheter locking solution, including antibiotics, thereby minimizing the lock solution's effect on the catheter tip. This study assessed the infection events that occurred in a series of hemodialysis patients using a non-side-hole catheter.

Over a period of 2 years, a novel symmetric-tip non-side-hole catheter was placed in 60 patients. Hemodialysis was performed thrice weekly. Prescribed dialyzer flows were 300-350 mL/min. Catheters were routinely locked with heparin 5000 units/mL between treatments. Patients were followed up for any catheter related complications, specifically infection events.

Seven events of catheter-related bloodstream infection occurred for a rate of 0.
