Objective: Most patients with psoriatic arthritis begin with cutaneous psoriasis, which is why all early detection strategies are based on screening in the dermatological consultation and referral to a rheu matologist. However, there are cases of patients who consult initially for musculoskeletal symptoms, mostly joint pain, regardless of family and/or personal history of psoriasis. This study aimed to esti mate the frequency of psoriatic arthritis in a cohort of patients who consulted for polyarthralgia and to determine the differential features, at the time of clinical presentation, in relation to both patients with final diagnosis other than psoriatic arthritis and patients with diagnosis of rheumatoid arthritis.

Background: The increasing number of clinical trials for induced pluripotent stem cell (iPSC)-derived cell therapy products makes the production on clinical grade iPSC more and more relevant and necessary. Cord blood banks are an ideal source of young, HLA-typed and virus screened starting material to produce HLA-homozygous iPSC lines for wide immune-compatibility allogenic cell therapy approaches. The production of such clinical grade iPSC lines (haplolines) involves particular attention to all steps since donor informed consent, cell procurement and a GMP-compliant cell isolation process.

COVID-19 outbreaks have had high mortality in low- and middle-income countries such as Ecuador. Human mobility is an important factor influencing the spread of diseases possibly leading to a high burden of disease at the country level. Drastic control measures, such as complete lockdown, are effective epidemic controls, yet in practice one hopes that a partial shutdown would suffice.

Reagent pencils allow for solvent-free deposition of reagents onto paper-based microfluidic devices. The pencils are portable, easy to use, extend the shelf-life of reagents, and offer a platform for customizing diagnostic devices at the point of care. In this work, reagent pencils were characterized by measuring the wear resistance of pencil cores made from polyethylene glycols (PEGs) with different molecular weights and incorporating various concentrations of three different reagents using a standard pin abrasion test, as well as by measuring the efficiency of reagent delivery from the pencils to the test zones of paper-based microfluidic devices using absorption spectroscopy and digital image colorimetry.
