In Situ Potentiometric Monitoring of Nitrate Removal from Aqueous Solution by Activated Carbon and Ion Exchange Resin.

A nitrate selective electrode was used for real-time in situ potentiometric monitoring of a batch nitrate removal process using activated carbon and ion exchange resin. A plasticized polymeric membrane consisting of polyvinyl chloride, 2-nitrophenyl octyl ether and tridodecyl methyl ammonium chloride was incorporated into an ion-selective electrode body. First, the dynamic potential response of the electrode to nitrate was investigated.

Secondary uncovered versus fully-covered metal stents for the management of occluded stent in unresectable distal malignant biliary obstruction.

Introduction: Self-expandable metallic stents (SEMS) have been widely placed for unresectable distal malignant biliary obstruction (UDMBO). However, the dysfunction rate is 19-40% and its treatment is controversial. We aimed asses the efficacy and safety of a secondary biliary stents (uncovered (UC) versus fully-covered (FC) stent) for the management of occluded SEMS.

A Delphi consensus on the management of Spanish patients with osteoporosis at high risk of fracture: OSARIDELPHI study.

Unlabelled: The OSARIDELPHI study evaluated the level of agreement between specialists in osteoporosis regarding the management of patients with high-risk fractures in Spain. The results provide expert-based recommendations for prevention, diagnosis, and treatment related to fracture risk. Therefore, the study facilitates clinical decision-making for managing this patient's profile.

Diffuse idiopathic skeletal hyperostosis (DISH) and trabecular bone score (TBS) in postmenopausal women: The Camargo cohort.

Objectives: The potential relationship between diffuse idiopathic skeletal hyperostosis (DISH) and bone microstructure has not been studied in women. We aimed to assess the association between the trabecular bone score (TBS) and DISH in postmenopausal women, as well as the role of other parameters related to bone metabolism, such as bone mineral density (BMD), calciotropic hormones, and bone remodeling markers.

Methods: Cross-sectional study, nested in a prospective population-based cohort (Camargo cohort).

Early stages of diffuse idiopathic skeletal hyperostosis (DISH) and chronic inflammation: the Camargo Cohort Study.

Introduction/objectives: DISH has traditionally been considered a non-inflammatory rheumatic disorder. Currently, an inflammatory component has been theorized in the early phases of this condition (EDISH). The study is aimed at investigating a possible relationship between EDISH and chronic inflammation.

Comparison of ANA testing by indirect immunofluorescence or solid-phase assays in a low pre-test probability population for systemic autoimmune disease: the Camargo Cohort.

Objectives: Autoantibodies and, specifically antinuclear antibodies (ANA), are the hallmark of systemic autoimmune diseases (AID). In the last decades, there has been great technical development to detect these autoantibodies along with an increased request for this test by clinicians, while the overall pre-test probability has decreased. In this study, we compare the diagnostic performance of three different methods for ANA screening (indirect immunofluorescence [IIF], addressable laser bead immunoassay [ALBIA], and fluorescence enzyme immunoassay [FEIA]).

High incidence of clinical fragility fractures in postmenopausal women with rheumatoid arthritis. A case-control study.

Objectives: To estimate the incidence of clinical fragility fractures in postmenopausal women with rheumatoid arthritis (RA) and analyze risk factors for fracture.

Methods: Incidence of clinical fragility fractures in 330 postmenopausal women with RA was compared to that of a control population of 660 age-matched postmenopausal Spanish women. Clinical fractures during the previous five years were recorded.

Adjusted global antiphospholipid syndrome score (aGAPSS) is useful to predict relapses in patients with retinal vein occlusion.

Background: A significant proportion of patients with retinal vein occlusion (RVO) are antiphospholipid antibodies (aPL) carriers. Relapsing disease occurs in nearly 10 % of cases and the role of aPL has not been established. The adjusted global antiphospholipid syndrome score (aGAPSS) was developed to assess the risk of clinical events in aPL carriers and its role in the management of RVO patients is unknown.

Bone Metabolism in Patients with Hidradenitis Suppurativa: A Case-control Study.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the hair follicles. The aim of this case-control study was to assess whether HS is associated with disturbances in trabecular bone score, bone mineral density, bone remodelling markers, and calciotropic hormones. A total of 81 patients and 79 controls of similar age and sex were included.

A genome-wide association study with tissue transcriptomics identifies genetic drivers for classic bladder exstrophy.

Classic bladder exstrophy represents the most severe end of all human congenital anomalies of the kidney and urinary tract and is associated with bladder cancer susceptibility. Previous genetic studies identified one locus to be involved in classic bladder exstrophy, but were limited to a restrict number of cohort. Here we show the largest classic bladder exstrophy genome-wide association analysis to date where we identify eight genome-wide significant loci, seven of which are novel.

Blood group O is associated with post-COVID-19 syndrome in outpatients with a low comorbidity index.

Background: ABO blood group system modulates the inflammatory response and has been implicated in COVID-19. Group O protects against SARS-CoV-2 infection, but there are no data regarding post-COVID-19 syndrome (PCS). Our aim was to assess this possible association.

Sarcopenic osteoporosis, sarcopenic obesity, and sarcopenic osteoporotic obesity in the Camargo cohort (Cantabria, Spain).

Unlabelled: The associations of sarcopenia with osteoporosis or obesity have a very low prevalence. No trend towards an association between osteoporosis and sarcopenia is observed. Sarcopenia and obesity tend not to coincide, as if they were antagonistic disorders.

Pharmacogenetics of Osteoporosis: A Pathway Analysis of the Genetic Influence on the Effects of Antiresorptive Drugs.

Osteoporosis is a skeletal disorder defined by a decreased bone mineral density (BMD) and an increased susceptibility to fractures. Bisphosphonates and selective oestrogen receptor modulators (SERM) are among the most widely used drugs. They inhibit bone resorption by targeting the mevalonate and oestrogen pathways, respectively.

Comorbidity and osteoporotic fracture: approach through predictive modeling techniques using the OSTEOMED registry.

Purpose: To examine the response to anti-osteoporotic treatment, considered as incident fragility fractures after a minimum follow-up of 1 year, according to sex, age, and number of comorbidities of the patients.

Methods: For this retrospective observational study, data from baseline and follow-up visits on the number of comorbidities, prescribed anti-osteoporotic treatment and vertebral, humerus or hip fractures in 993 patients from the OSTEOMED registry were analyzed using logistic regression and an artificial network model.

Results: Logistic regression showed that the probability of reducing fractures for each anti-osteoporotic treatment considered was independent of sex, age, and the number of comorbidities, increasing significantly only in males taking vitamin D (OR = 7.

Impact of the SARS-CoV-2 pandemic on pancreatic cancer: diagnosis and short-term survival.

Introduction: The COVID-19 pandemic has delayed medical consultation, possibly leading to the diagnosis of gastrointestinal cancer. The aim of the study was to analyze the impact of SARS-Cov-2 pandemic on new diagnosis and short-term survival of patients with pancreatic cancer (PC).

Methods: All consecutive patients who had a suspected diagnosis of pancreatic lesion before (from March to September 2019) and during COVID 19 pandemic (from March to September 2020).

Post-COVID-19 syndrome, low-grade inflammation and inflammatory markers: a cross-sectional study.

Objective: Post-COVID syndrome (PCS) is a poorly known entity. An underlying chronic, low-grade inflammation (LGI) has been theorized as a pathophysiological mechanism. Available data on biomarkers in PCS show conflicting results.

Vitamin D Status in Hospitalized Patients with SARS-CoV-2 Infection.

Background: The role of vitamin D status in COVID-19 patients is a matter of debate.

Objectives: To assess serum 25-hydroxyvitamin D (25OHD) levels in hospitalized patients with COVID-19 and to analyze the possible influence of vitamin D status on disease severity.

Methods: Retrospective case-control study of 216 COVID-19 patients and 197 population-based controls.
