Objective: Global thyroid cancer (TC) incidence is growing worldwide, but great heterogenicity exists among published studies, and thus, population-specific epidemiological studies are needed to adequate health resources and evaluate the impact of overdiagnosis., Methods: We conducted a Public Health System database retrospective review of TC incident cases from 2000 to 2020 in the Balearic Islands region and evaluated age-standardized incidence rate (ASIR), age at diagnosis, gender distribution, tumor size and histological subtype, mortality rate (MR), and cause of death. Estimated annual percent changes (EAPCs) were also evaluated and data from the 2000-2009 period were compared to the 2010-2020 period when neck ultrasound (US) was routinely performed by clinicians at Endocrinology Departments., Results: A total of 1387 incident cases of TC were detected. Overall, ASIR (×105) was 5.01 with a 7.82% increment in EAPC. A significant increase in the 2010-2020 period was seen for ASIR (6.99 vs 2.82, P < 0.001) and age at diagnosis (52.11 vs 47.32, P < 0.001) compared to the 2000-2009 period. A reduction in tumor size (2.00 vs 2.78 cm, P < 0.001) and a 6.31% increase in micropapillary TC (P < 0.05) were also seen. Disease-specific MR remained stable at 0.21 (×105). The mean age at diagnosis for all mortality groups was older than survivors (P < 0.001)., Conclusion: The incidence of TC has grown in the 2000-2020 period in the Balearic Islands, but MR has not changed. Beyond other factors, a significant contribution of overdiagnosis to this increased incidence is likely due to changes in the routine management of thyroid nodular disease and increased availability of neck US.

Recurrence of uropathogenic Escherichia coli (UPEC) infections has been attributed to reactivation of quiescent intracellular reservoirs (QIRs) in deep layers of the bladder wall. QIRs are thought to arise late during infection following dispersal of bacteria from intracellular bacterial communities (IBCs) in superficial umbrella cells. Here, we track the formation of QIR-like bacteria in a bladder organoid model that recapitulates the stratified uroepithelium within a volume suitable for high-resolution live-cell imaging. Bacteria injected into the organoid lumen enter umbrella-like cells and proliferate to form IBC-like bodies. In parallel, single bacteria penetrate deeper layers of the organoid wall, where they localize within or between uroepithelial cells. These "solitary" bacteria evade killing by antibiotics and neutrophils and are morphologically distinct from bacteria in IBCs. We conclude that bacteria with QIR-like properties may arise at early stages of infection, independent of IBC formation and rupture., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2021 The Authors.

Many deaf women face the lack of numerous resources related to their personal development. The unavailability of proper information on Sexual and Reproductive Health (SRH), in particular, causes problems of sexually transmitted infections, unwanted pregnancy in adolescence, sexual violence, complications during pregnancy, etc. In response to this, we have created a social network that delivers SRH content (verified and validated by experts) to women with different degrees of hearing loss. The site features a recommender system that selects the most relevant pieces of content to deliver to each woman, driven by her individual preferences, needs and levels of knowledge on the different subjects. We report experiments conducted in Cuenca, Ecuador, between 2017 and 2018 with 98 volunteers from low- and middle-income settings, aiming to evaluate the quality and appeal of the contents, the coherence of the methodology followed to create them, and the effectiveness of the content recommendations. The positive results encourage the frequent creation of new content and the refinement of the recommendation logic as the cohort of users expands over time.

The advent of the autonomous car is paving the road to the realization of ideas that will help optimize traffic flows, increase safety and reduce fuel consumption, among other advantages. We present one proposal to bring together Virtual Traffics Lights (VTLs) and platooning in urban scenarios, leaning on vehicle-to-vehicle (V2V) communication protocols that turn intersections into virtual containers of data. Newly-introduced protocols for the combined management of VTLs and platoons are validated by simulation, comparing a range of routing protocols for the vehicular networks with the baseline given by common deployments of traditional traffic lights ruled by state-of-the-art policies. The simulation results show that the combination of VTLs and platoons can achieve significant reductions in travel times and fuel consumption, provided that proper algorithms are used to handle the V2V communications.

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a genetic syndrome that may present with hypocalcemia due to primary hypoparathyroidism (PH) at any age. We report a new diagnosis of 22q11.2DS in a 57-year-old man who presented with symptomatic hypocalcemia. It is important to consider genetic causes of hypocalcemia due to PH regardless of age., Learning Points: It is important to discard genetic cause of primary hypoparathyroidism in a patient without autoimmune disease or prior neck surgery.A new diagnosis of a hereditary disease has familial implications and needs genetic counselling.It is also important to discard other syndrome's comorbidities.
