Article Synopsis
  • The study investigates how effective lung ultrasound is in monitoring patients after they've been discharged from the hospital following SARS-CoV-2 pneumonia.
  • It reviews existing research from various databases to examine persistent changes in lung ultrasound for these COVID-19 patients, using specific criteria to select and assess the quality of the studies.
  • The findings indicate that many patients show ongoing lung abnormalities two to six months post-infection, with these abnormalities correlated to the severity of their initial pneumonia episode, highlighting the benefits of using lung ultrasound in follow-up care.

Article Synopsis
  • HIV is a virus that can't be completely cured yet because it hides in certain immune cells and regular medicines can't get rid of it.
  • Scientists are working on finding special drugs called latency reversing agents (LRAs) that can activate these hidden viruses so they can be treated.
  • A study showed that a drug called maraviroc can wake up the dormant HIV, but the virus quickly came back after stopping treatment, so more research is needed to really get rid of the virus for good.

Background: HIV/AIDS progression is linked to vitamin D, which is regulated by several key cytochromes P450 (CYP). Single nucleotide polymorphisms (SNPs) in CYP genes influence vitamin D metabolism and serum levels. The objective of this study was to evaluate the association between CYP SNPs and the clinical AIDS progression in antiretroviral treatment (ART)-naïve HIV-infected patients.

We conducted a retrospective observational study to demonstrate that switching to insulin degludec from other long-acting insulins reduces the risk of hypoglycaemia events and improves glycaemic control in patients with type 2 diabetes and stage 2-3B chronic kidney disease.

Background: The PROFUND index (PI) is a prognostic scale for polypathological patients at 12 months. The objective of the study was to validate the PI as a predictor of 1-year mortality in a current cohort of polypathological patients and analyse its prognostic usefulness in the short-term (1 month and 3 months) after discharge from Internal Medicine.

Design: We conducted a prospective observational study and all polypathological patients discharged from an Internal Medicine Department between 01 March 2016 and 28 February 2017 were enrolled.

Objectives: To study the incidence and prevalence of primary systemic vasculitides (PSV) in the Costa del Sol region (southern Spain) and to compare the major epidemiological studies in PSV with the results obtained in our area.

Methods: Retrospective study including permanent residents ≥14 years (or older) diagnosed with PSV at the Hospital Costa del Sol (Marbella, Spain) between 1994 and 2010. Epidemiological data were collected and the annual incidence rate during the study period and the prevalence in 2010 were calculated per million population, except for GCA, which was estimated per 100,000 population >50 years.

Background: The proportion of asymptomatic individuals infected by influenza AH1N1v varies depending on the studies. Health personnel were exposed to the AH1N1v virus due to their professional activity, thus an high seroprevalence to the virus could be expected in the absence of symptomatology. The objective of this study was to determine the prevalence of asymptomatic individuals serologically positive for influenza AH1N1v virus.

Objective: To describe the profile of people suffering Invasive Meningococcal Disease in Andalusia and the Canary Islands, and identify the risk factors for death.

Material And Methods: A retrospective study was designed, recruiting cases from week 41 of 1995 to week 40 2000. Cases were probable or definite, and were extracted from the databases of the hospital by examining diagnosis at discharge or death.
