Assessing the impact of long-term inhaled corticosteroid therapy on patients with COVID-19 and coexisting chronic lung disease: A multicenter retrospective cohort study.

Background: Patients with chronic lung disease (CLD), such as asthma or chronic obstructive pulmonary disease, were expected to have an increased risk of clinical manifestations and severity of COVID-19. However, these comorbidities have been reported less frequently than expected. Chronic treatment with inhaled corticosteroids (ICS) may impact the clinical course of COVID-19.

The role of calcium and vitamin D dietary intake on risk of colorectal cancer: systematic review and meta-analysis of case-control studies.

Purpose: The aim of this study is to analyze the current evidence about the relationships between calcium/vitamin D and CRC based on case-control studies according to sex, tumor location and continental region to complement the information obtained in meta-analyses of other designs.

Methods: The articles were located in three databases (PUBMED, EMBASE and SCOPUS), they should be written in English language, with a case and control design and published between 1 January 1970 and 31 October 2019.

Results: There were 37 selected studies, 32 for intake of calcium, that involved 24,353 CRC cases and 30,650 controls, and 23 for that of VIT D, with a total of 19,076 cases and 36.

Evolution of the Use of Corticosteroids for the Treatment of Hospitalised COVID-19 Patients in Spain between March and November 2020: SEMI-COVID National Registry.

Objectives: Since the results of the RECOVERY trial, WHO recommendations about the use of corticosteroids (CTs) in COVID-19 have changed. The aim of the study is to analyse the evolutive use of CTs in Spain during the pandemic to assess the potential influence of new recommendations.

Material And Methods: A retrospective, descriptive, and observational study was conducted on adults hospitalised due to COVID-19 in Spain who were included in the SEMI-COVID-19 Registry from March to November 2020.

Colorectal cancer, sun exposure and dietary vitamin D and calcium intake in the MCC-Spain study.

Objectives: To explore the association of colorectal cancer with environmental solar radiation and sun exposure behavior, considering phenotypic variables (eye color, hair color and skin phenotype), dietary intake of vitamin D and calcium, and socio-demographic factors.

Study Design: Multicenter population-based frequency matched case-control study in Spain (MCC-Spain), with 2140 CRC cases and 3950 controls.

Methods: Data were obtained through personal interviews using a structured epidemiological questionnaire that included socio-demographic data, residential history, environmental exposures, behavior, phenotypic and dietary information.

Purple urine bag syndrome, a travel companion.

Objective: Purple urine bag syndrome is a rare entity that appears in elderly patients with long-term urinary catheters with chronic diseases.

Method: We describe the cases of two patients admitted to our service, who serve as example to illustrate this pathology and which process should be followed in its diagnosis and treatment.

Conclusion: Purple urine bag syndrome is a rare entity that occurs more frequently in elderly patients, women, with long-term urinary catheters, whose main factors are debilitating diseases, prolonged immobility and chronic constipation.

[HCV and HIV infection, and coinfection in the León health area in the period 1993-2004].

Background: As few population studies exist, the study of positive serological tests detected in laboratory services may be an acceptable approximation for the assessment of HIV and Hepatitis C infection and coinfection by both.

Methods: A study was made of the database of positive serologies of the Laboratory Service of León General Hospital. Data were treated in accordance with the origin of the samples.

[Gastric tuberculosis. Review apropos of a case].
