The association between C-reactive protein to albumin ratio and 6-month neurological outcome in patients with in-hospital cardiac arrest

The global incidence rates of in-hospital cardiac arrest(IHCA)range from1.2 to 9.0 per1,000 hospitalized patients,as per the National Cardiac Arrest Database.[1] While IHCAs tend to exhibit superior 30-day survival rates relative to out-of-hospital cardiac arrests (OHCA) due to situational advantages,such as immediate access to medical personnel and treatments.

Measles outbreaks in the Kyeongin area of the Republic of Korea,2013-2014:A single-center experience in a country of measles elimination

Objective: To identify the source of infection and determine the clinical features and laboratory finding of measles infection,Methods: In 27 measles patients,except for 3 adult patients,the rest of 24 pediatric measles cases were analyzed with regard to age,sex,immunization status,transmission routes and molecular genotyping of measles virus,Eighteen measles patients who admitted in isolation ward were set apart to investigate clinical findings and its correlation with laboratory characteristics,Retrospective analysis of cases was conducted in this study,Results: Of the 24 pediatric patients,23(95.8%) had not received any measles-containing vaccine(MCV),Sixteen of the patients(66.7%) were aged <12 months,The suspicious index case of a girl aged 34 months was not vaccinated with MCV1 and got measles after a trip to Philippines,and molecular genotype was revealed as B3,Measles outbreaks in the community such as a restaurant were followed by this one imported case,According to analysis of 18 patients admitted in isolation ward,the median level of C-reactive protein(CRP) was 0.38 mg/d L and that of lactate dehydrogenase(LDH) was 1 200 IU/L,All of the 18 patients had LDH levels above the normal range,Age correlated with CRP(ρ = 0.528,P = 0.024) and LDH(ρ = 0.501,P = 0.034),The duration of fever was correlated with the duration of fever before rash(ρ = 0.898,P < 0.01),The duration of hospitalization was correlated with CRP(ρ = 0.586,P = 0.011),The white blood cell counts were correlated with the levels of LDH(ρ = 0.505,P = 0.033),aspartate aminotransferase(ρ = 0.507,P = 0.032),and alanine aminotransferase(ρ = 0.481,P = 0.043),Conclusions: Early weaning of maternally derived measles antibodies therefore vaccination of MCV1 at a young age from 9 months to 12 months should be considered in situations of early exposure,Furthermore there is a call for consideration of scheduling an earlier age for the first dose of MMR vaccine in Europe,It is necessary for Korea to investigate the duration of the presence and quantitative analysis of maternal measles antibodies in infants and to reconsider the timing of MCV1.

The protective roles of integrin α4β7 and Amphiregulin-expressing innate lymphoid cells in lupus nephritis

Type 2 innate lymphoid cells (ILC2s) have emerged as key regulators of the immune response in renal inflammatory diseases such as lupus nephritis. However, the mechanisms underlying ILC2 adhesion and migration in the kidney remain poorly understood. Here, we revealed the critical role of integrin α4β7 in mediating renal ILC2 adhesion and function. We found that integrin α4β7 enables the retention of ILC2s in the kidney by binding to VCAM-1, E-cadherin, or fibronectin on structural cells. Moreover, integrin α4β7 knockdown reduced the production of the reparative cytokine amphiregulin (Areg) by ILC2s. In lupus nephritis, TLR7/9 signaling within the kidney microenvironment downregulates integrin α4β7 expression, leading to decreased Areg production and promoting the egress of ILC2s. Notably, IL-33 treatment upregulated integrin α4β7 and Areg expression in ILC2s, thereby enhancing survival and reducing inflammation in lupus nephritis. Together, these findings highlight the potential of targeting ILC2 adhesion as a therapeutic strategy for autoimmune kidney diseases.
