Purpose Of Review: The new guidelines for assessment of asthma control emphasize two domains: impairment and risk. Exacerbations of asthma are an important component of risk but have not received as much attention as the day-to-day symptoms that make up impairment. The purpose of this review is to report what has recently been learned about exacerbations.
Recent Findings: Exacerbations occur in the context of both controlled and uncontrolled asthma. Exacerbations are a strong independent risk factor of further exacerbations. This suggests that unrecognized factors may be involved in susceptibility to exacerbations in addition to more commonly recognized triggers such as viruses, allergens, and poorly controlled asthma. Such factors may be the result of genetic variation. Recent evidence now shows a residual effect on lung function from an exacerbation event. There are no current specific intervention measures to prevent exacerbations but attention to management practices continues to look at the role of the emergency department in improving care.
Summary: The presence of exacerbations is considered a risk factor of the likelihood of further exacerbations and requires assessment of the triggers identified with history of exacerbations, host factors, atopic disposition, exposure to allergens, adherence to prescribed medications, and preventive measures to reduce future risk of such an event.

Objective To investigate the effects and molecular mechanism of Homer protein homolog 1a (Homer 1a) overexpression on nerve injury in mice with traumatic brain injury (TBI). Methods Sixty male C57BL/6 mice were randomly divided into five groups: sham group, TBI group, empty lentivirus (Lv-NC) group, Homer 1a overexpression lentivirus (Lv-Homer 1a) group and Lv-Homer 1a + 740 Y-P group, with 12 mice in each group. The lentivirus was orthotopic injected into the cerebral cortex of mice 5 d before modeling, while 740 Y-P was injected intraperitoneally 1 d before modeling.

Objective The prevalence of drug-resistant Mycobacterium tuberculosis (Mtb) strains is exacerbating the global burden of tuberculosis (TB), highlighting the urgent need for new treatment strategies for TB. Methods The recombinant adenovirus vaccine expressing cyclic di-adenosine monophosphate (c-di-AMP) phosphodiesterase B (CnpB) (rAd-CnpB), was administered to normal mice via mucosal immunization, either alone or in combination with drug therapy, to treat Mtb respiratory infections in mice.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of antibodies in serum and bronchoalveolar lavage fluid (BALF).

Climate change is an emerging global health crisis, disproportionately affecting low- and middle-income countries (LMICs) where health outcomes are increasingly compromised by environmental stressors such as pollution, natural disasters, and human migration. With a focus on promoting health equity, Global Surgery advocates for expanding access to surgical care and enhancing health outcomes, particularly in resource-limited and disaster-affected areas like LMICs. The healthcare industry-and more specifically, surgical care-significantly contributes to the global carbon footprint, primarily through resource-intensive settings, i.

The Arabian Peninsula (AP) has been reported to experience increasing drought in recent decades. With this background, this study evaluates best performing Climate Model Intercomparison Project 6 (CMIP6) Global Climate Models (GCMs) for historical (1985-2014) simulations and future drought projections across the AP until 2100, using the standardized precipitation index (SPI) and standardized precipitation-evapotranspiration index (SPEI). We assess uncertainties from model differences, scenarios, timescales, and methods.
