Lower airway colonisation with species of potentially pathogenic bacteria (PPB) is associated with defective bacterial phagocytosis, in monocyte-derived macrophages (MDMs) and alveolar macrophages, from tobacco smoke-associated chronic obstructive pulmonary disease (S-COPD) subjects. In the developing world, COPD among nonsmokers is largely due to biomass smoke (BMS) exposure; however, little is known about PPB colonisation and its association with impaired innate immunity in these subjects. We investigated the PPB load (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Pseudomonas aeruginosa) in BMS-exposed COPD (BMS-COPD) subjects compared with S-COPD and spirometrically normal subjects. ⋯ Higher bacterial loads of S. pneumoniae, H. influenzae and P. aeruginosa were observed in BMS-COPD subjects. Increased PPB load in BMS-exposed subjects was significantly negatively associated with defective phagocytosis in MDMs and spirometric lung function indices (p<0.05). Increased PPB load in airways of BMS-COPD subjects is inversely associated with defective bacterial phagocytosis and lung function.

COPD screening guidelines in patients with HIV are lacking, and data about its under-diagnosis are still limited. This study aimed to determinate the feasibility of a case-finding program and the prevalence of COPD under-diagnosis in a large cohort of HIV-infected subjects. ⋯ COPD may be under-diagnosed in HIV-infected people, and case-finding programs are an urgent issue to address as part of routine practice in these individuals.

To determine the effectiveness of basal membranotomy performed to ensure cerebral expansion in patients operated for chronic subdural hematoma. ⋯ The mini craniotomy-basal membranotomy technique provided statistically significantly better cerebral expansion in patients with chronic subdural hematoma when compared with the double burr hole drainage technique.

ReviewVirtual reality as an analgesic for acute and chronic pain in adults: a systematic review and meta-analysis.
Background: Previous studies have shown that virtual reality (VR) is effective in reducing acute and chronic pain both in adults and in children. Given the emergence of new VR technology, and the growing body of research surrounding VR and pain management, an updated systematic review is warranted. Purpose: The purpose of this systematic review is to compare the effectiveness of VR in reducing acute and chronic pain in adults. ⋯ Limitations: Due to heterogeneity, we were unable to perform meta-analyses for all study populations and pain conditions. Conclusions: VR is an effective treatment for reducing acute pain. There is some research that suggests VR can reduce chronic pain during the intervention; however, more evidence is needed to conclude that VR is effective for lasting reductions in chronic pain.
