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.

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

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

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.
