Collectively, these results indicate a novel histamine production mechanism by macrophages, in which Th2 cells and macrophages cooperatively induce nasal allergic inflammation through histamine signaling.Community-acquired pneumonia (CAP) is a respiratory disease frequently requiring hospital admission, and a significant cause of death worldwide. This study aimed to investigate the prognostic value of clinical indicators. A prospective, multi-center study was conducted (January 2017-December 2018) where patient demographic and clinical data were recorded (N = 366). The 30-day mortality rate was 5.46%. Cox Regression analyses showed that serum albumin (ALB) and respiratory rate (RR) were independent prognostic variables for 30-day survival in patients with CAP. Albumin negatively correlated with the Pneumonia Severity Index (PSI) and CURB-65 scores using Pearson and Spearman tests. PF-05212384 Survival curves showed that a RR >24 breaths/min or ALB ≤30 g/L were associated with a significantly higher risk of mortality. The area-under-the-curve (AUC) for predicting 30-day mortality in patients with CAP was 0.762, 0.763, 0.790, and 0.784 for ALB, RR, PSI, and CURB-65, respectively. The AUC for the prediction of 30-day mortality using ALB combined with PSI, CURB-65 scores, and RR was 0.822 (95% CI 0.731-0.912), 0.847 (95% CI 0.755-0.938), and 0.847 (95% CI 0.738-0.955), respectively. Albumin and RR were found to be reliable prognostic factors for CAP. This combination showed equal predictive value when compared to adding ALB assessment to PSI and CURB-65 scores, which could improve their prognostic accuracy.Humans are frequently exposed to bacterial genotoxins of the gut microbiota, such as colibactin and cytolethal distending toxin (CDT). In the present study, whole genome microarray-based identification of differentially expressed genes was performed in vitro on HT29 intestinal cells while following the ectopic expression of the active CdtB subunit of Helicobacter hepaticus CDT. Microarray data showed a CdtB-dependent upregulation of transcripts involved in positive regulation of autophagy concomitant with the downregulation of transcripts involved in negative regulation of autophagy. CdtB promotes the activation of autophagy in intestinal and hepatic cell lines. Experiments with cells lacking autophagy related genes, ATG5 and ATG7 infected with CDT- and colibactin-producing bacteria revealed that autophagy protects cells against the genotoxin-induced apoptotic cell death. Autophagy induction could also be associated with nucleoplasmic reticulum (NR) formation following DNA damage induced by these bacterial genotoxins. In addition, both genotoxins promote the accumulation of the autophagic receptor P62/SQSTM1 aggregates, which colocalized with foci concentrating the RNA binding protein UNR/CSDE1. Some of these aggregates were deeply invaginated in NR in distended nuclei together or in the vicinity of UNR-rich foci. Interestingly, micronuclei-like structures and some vesicles containing chromatin and γH2AX foci were found surrounded with P62/SQSTM1 and/or the autophagosome marker LC3. This study suggests that autophagy and P62/SQSTM1 regulate the abundance of micronuclei-like structures and are involved in cell survival following the DNA damage induced by CDT and colibactin. Similar effects were observed in response to DNA damaging chemotherapeutic agents, offering new insights into the context of resistance of cancer cells to therapies inducing DNA damage.
There are currently 1.5 million indigenous people in Bangladesh, constituting 1.8% of the total population and representing one of the country's most deprived communities. This study explores the health status and quality of life along with their determinants among indigenous older people in Bangladesh in order to fill the knowledge and evidence gap on this topic.

A mixed-methods approach was deployed in October 2019 in the Sylhet division of Bangladesh which involved a cross-sectional survey among 400 indigenous older adults (200 males, 200 females) from 8 tea gardens using a pre-tested semi-structured questionnaire. Ten in-depth interviews were also conducted with providers of the tea garden health facilities. Descriptive analysis, multiple logistic and multi-nominal linear regression were performed to explore associated factors around health and quality of life.

Of the total respondents, the majority (79.5%) had chronic diseases, with visual difficulty being predominant (74%) among the conditions. Alconditions and poor quality of life. Health literacy and health seeking behaviour is poor among indigenous older adults generally and there is a huge gap in the health services and social supports available to them.Species taxa are the units of taxonomy most suited to measure virus diversity, and they account for more than 70% of all virus taxa. Yet, as evidenced by the content of GenBank entries and illustrated by the recent literature on SARS-CoV-2, they are the most neglected taxa of virus research. To correct this disparity, we propose to make species taxa a first choice for communicating virus taxonomy in publications concerning viruses. We see it as a key step toward promoting research on diverse viruses, including pathogens, at this fundamental level of biology.
Cow milk is an important source of macro-and micronutrients. However, it has low iron content but high content of casein and calcium thus could negatively influence hemoglobin synthesis. On the other hand, camel milk contains higher iron concentration than cow milk. In addition, the majority of iron in camel milk is associated with the lower molecular fraction of casein suggesting better bioavailability. Furthermore, vitamin C concentration, a useful iron absorption enhancer, is more than three-fold greater in camel milk than cow milk. This study compared hemoglobin concentration among young children consuming consistently cow milk or camel milk.

Hemoglobin concentration of young children (aged 6-59 mo) from settled pastoralist communities of the Somali region, Ethiopia, consistently consuming cow milk (n = 166) or camel milk (n = 166) was determined. In addition, socio-demographic and water, sanitation, and hygienic (WASH) conditions of study participants' households were captured. Furthermore, dietary intake and anthropometric characteristics of participating children were assessed.
