Meta Analysis
Association between apnea-hypopnea index and coronary artery calcification: a systematic review and meta-analysis.
The present study aimed to evaluate the association between presence and severity of obstructive sleep apnoea (OSA) and the presence of subclinical coronary artery disease (CAD) as assessed by coronary calcium score. ⋯ In participants without symptomatic coronary disease, the presence of OSA was associated with the presence and extent of CAC. However, potential confounders such as age, gender, and BMI and the diversity of CAC scores may affect the association.

Meta Analysis
The use of statins was associated with reduced COVID-19 mortality: a systematic review and meta-analysis.
Statins are widely used to treat people with metabolic and cardiovascular disorders. The effect of statins on coronavirus disease 2019 (COVID-19) is unclear. To investigate the association between statins and COVID-19 outcomes and, if possible, identify the subgroup population that benefits most from statin use. ⋯ The use of statins was significantly associated with a reduced need for IMV and decreased mortality among individuals with COVID-19. Statins may not need to be discontinued because of concern for COVID-19 on admission. Further randomized controlled trial (RCTs) are needed to clarify the causal effect between statin use and severe COVID-19 outcomes.Key messagesParticipants in five types of studies were shown to have even lower odds of death when taking statins.The use of statins was significantly associated with a reduced need for invasive mechanical ventilation and decreased all-cause mortality among individuals with COVID-19. However, statin use did not prevent participants from needing care in the intensive care unit.The results justify performing randomized controlled trials (RCTs) to validate the benefits of statins on COVID-19 outcomes.

Meta Analysis
Venous thrombotic events in psoriasis patients: a systematic review with meta-analysis.
Psoriasis is a chronic inflammatory skin disease associated with numerous comorbidities. Psoriasis has been linked to an increased risk of metabolic syndrome and atherosclerotic arterial disease. Inflammatory conditions are known to increase the risk of venous thromboembolism (VTE), a frequent cause of morbidity and mortality. However, the relationship between psoriasis and VTE has received little attention and existing studies have shown conflicting results. ⋯ Published data adjusted for key confounders demonstrate in general a significantly increased prevalence of VTE in psoriasis patients. Both psoriasis severity and number of confounders assessed seem to have an impact on this correlation. In this review, we pooled unadjusted data of the studies and we found a non-significant increased risk for VTE in psoriasis patients compared to healthy controls. This discrepancy suggests that psoriasis severity, age, gender or comorbidities may influence the risk of VTE in subgroups of the psoriasis population. Future research to identify subgroups at risk for VTE is warranted.Key messagesThe included studies reported an increased risk of VTE, DVT, PE and RVO in psoriasis patients.A meta-analysis was performed on five studies that reported raw data and showed that the pooled risk ratio for VTE in psoriasis patients overall was increased, however not significantly, compared to healthy controls.Further research to pinpoint psoriasis subgroups at risk (e.g. severe psoriasis patients, younger age, associated comorbidities) of developing VTE is warranted.

Thoracic sympathectomy for the treatment of primary axillary hyperhidrosis: systematic review and proportional meta-analysis.
Primary hyperhidrosis is a disorder that involves excessive sweat production, which has a negative impact on the quality of life. ⋯ This review demonstrated that thoracic sympathectomy by VATS is a viable and safe option for the treatment of PAH. There was no difference between high and lower levels of resection. However, the estimation of the effect is quite uncertain because the quality of evidence was extremely low.Key messagePure axillary hyperhidrosis has great potential to compromise quality of life.Surgery should be indicated only when clinical treatment fails.Thoracic sympathectomy by video-assisted thoracoscopy is a viable and safe option for the treatment of primary axillary hyperhidrosis.

Background. Chronic cough is a disabling condition with a high proportion of diagnostic and therapeutic failures. Fractional exhaled nitric oxide (FeNO) has been considered a useful biomarker for predicting inhaled corticosteroids (ICS) response. ⋯ Key messagesChronic cough is a disabling condition with a high proportion of diagnostic and therapeutic failures. Fractional exhaled nitric oxide (FeNO) may be a useful biomarker for identifying chronic cough patients who respond to steroid treatment. A FeNO cut-off lower than 25 ppb should be considered irrelevant for this clinical application.
