Antiphospholipid antibodies and chance of post-COVID-19 vaccine thrombophilia: The actual straw which smashes the camel's back again?
These results suggest that prenatal BPA exposure has an amplifying effect on avoidance responses to predator odor stress.Environmental biological and chemical agents can modulate innate and acquired immunity in the lung via the stimulation of Toll-like receptors (TLRs). To investigate the effect of environmental chemical agents on the activation of NF-κB and activator protein (AP)-1 subunits and the role of TLR4 signaling in the lung, C3H/HeN and C3H/HeJ (TLR4-defective) mice were exposed to 0 or 50 ppm of toluene for 6 hr/day, 5 days/week for 6 weeks. Some groups of mice were also stimulated with OVA or LPS as a biological agent. The DNA-binding activities of the NF-κB subunits (p50, p52, p65 and RelB) and AP-1 family members (FosB, c-Fos, +c-Jun, JunD) were compared using TransAM ELISA kits. Exposure to toluene alone produced no significant changes in both mice. Although stimulation with OVA or LPS alone significantly increased the DNA binding activities of p50 and p52 in C3H/HeN mice, there were no interactions between biological factors and toluene. In the C3H/HeJ mice, stimulation with OVA or LPS increased p65 and p52 binding activity and the combination of exposure to toluene and OVA significantly increased the DNA binding activities of the p65 and p52 in the lung. During AP-1 activation, co-exposure to toluene and OVA increased JunD binding activity in C3H/HeJ mice, while co-exposure to toluene and LPS influenced c-Fos binding activity in C3H/HeN mice. These results indicate that TLR4 may play an important role in activation of NF-κB or AP-1 family following exposure to environmental biological and chemical agents.Nicardipine hydrochloride (NIC) injection has been widely used for emergency treatment of abnormally high blood pressure. However, NIC injection often causes severe peripheral vascular injury. The purpose of the present study was to reduce the NIC-induced cell injury in human vascular endothelial cells by use of clinical agents. The mechanism of NIC-induced cell injury was evaluated by time-lapse microscopic imaging, autophagosome staining with monodansylcadaverine, immunostaining of light chain 3 isoform B (LC-3B) and assessment of cell viability after exposure to NIC with or without an inhibitor of autophagosome formation (3-methyladenine, 3-MA). Results from autophagosome labeling and immunostaining of LC-3B revealed an increase of autophagosomes and LC-3B in NIC-treated cells. NIC-mediated reduction of cell viability was inhibited by 3-methyladenine. Moreover, we found that N-acetylcysteine (NAC) reduced NIC-induced cell injury in human vascular endothelial cells. These findings suggest that NIC causes severe peripheral venous irritation via induction of autophagic cell death and that inhibition of autophagy with NAC could contribute to the reduction of NIC-induced vascular injury.Air freshener could be one of the multiple sources that release volatile organic compounds (VOCs) into the indoor environment. The use of these products may be associated with an increase in the measured level of terpene, such as xylene and other volatile air freshener components, including aldehydes, and esters. Air freshener is usually used indoors, and thus some compounds emitted from air freshener may have potentially harmful health impacts, including sensory irritation, respiratory symptoms, and dysfunction of the lungs. The constituents of air fresheners can react with ozone to produce secondary pollutants such as formaldehyde, secondary organic aerosol (SOA), oxidative product, and ultrafine particles. These pollutants then adversely affect human health, in many ways such as damage to the central nervous system, alteration of hormone levels, etc. In particular, the ultrafine particles may induce severe adverse effects on diverse organs, including the pulmonary and cardiovascular systems. Although the indoor use of air freshener is increasing, deleterious effects do not manifest for many years, making it difficult to identify air freshener-associated symptoms. In addition, risk assessment recognizes the association between air fresheners and adverse health effects, but the distinct causal relationship remains unclear. In this review, the emitted components of air freshener, including benzene, phthalate, and limonene, were described. Moreover, we focused on the health effects of these chemicals and secondary pollutants formed by the reaction with ozone. In conclusion, scientific guidelines on emission and exposure as well as risk characterization of air freshener need to be established.
To examine associations of gain in body mass index (BMI) and linear growth from term to 18 months with asthma at age 8 years in a cohort of preterm infants. We hypothesised that rapid BMI gain would increase asthma risk, whereas rapid linear growth would be protective.

Observational secondary analysis of data from the Infant Health and Development Program.

8 centres in the USA.

863 preterm (≤37 weeks), low birthweight (≤2500 g) children.

Gain in BMI and linear growth from term to 4 months, 4-12 months and 12-18 months, in z-scores.

Asthma at age 8 years, assessed by parent report of the child ever receiving the diagnosis from a doctor.

At age 8 years, 149 (17%) had ever been diagnosed with asthma. Adjusting for maternal and child factors in logistic regression, for each additional z-score gain in BMI from term to 4 months, odds of asthma at age 8 years were higher (OR 1.3, 95% CI 1.1 to 1.5); findings were similar for BMI gain from 4-12 months. More rapid linear growth from term to 4 months was not associated with lower odds of asthma (OR 1.1, 95% CI 0.9 to 1.3), with similar findings for 4-12 months and 12-18 months.

More rapid BMI gain in the 1st year of life was associated with higher odds of asthma, whereas linear growth did not appear protective. Our results add to mounting evidence that excess weight gain after term may be harmful to preterm infants.

Heating and humidification of inspired gases is routine during neonatal non-invasive respiratory support. However, little is known about the temperature and humidity delivered to the upper airway. The International Standards Organization (ISO) specifies that for all patients with an artificial airway humidifiers should deliver ≥33 g/m(3) absolute humidity (AH). We assessed the oropharyngeal temperature and humidity during different non-invasive support modes in a neonatal manikin study.

Six different modes of non-invasive respiratory support were applied at clinically relevant settings to a neonatal manikin, placed in a warmed and humidified neonatal incubator. Oropharyngeal temperature and relative humidity (RH) were assessed using a thermohygrometer. AH was subsequently calculated.

Measured temperature and RH varied between devices. Bubble and ventilator continuous positive airway pressure (CPAP) produced temperatures >34°C and AH >38 g/m(3). Variable flow CPAP resulted in lower levels of AH than bubble or ventilator CPAP, and AH decreased with higher gas flow. High-flow (HF) therapy delivered by Optiflow Junior produced higher AH with higher gas flow, whereas with Vapotherm HF the converse was true.

Different non-invasive devices deliver inspiratory gases of variable temperature and humidity. Most AH levels were above the ISO recommendation; however, with some HF and variable flow CPAP devices at higher gas flow this was not achieved. Clinicians should be aware of differences in the efficacy of heating and humidification when choosing modes of non-invasive respiratory support.

Behavioral health organizations have opportunities to create culturally competent and responsive services. But we need to add another call to action-acknowledging and addressing the disparities caused by racism.Many bacterial species are highly social, adaptively shaping their local environment through the production of secreted molecules. This can, in turn, alter interaction strengths among species and modify community composition. However, the relative importance of such behaviours in determining the structure of complex communities is unknown. Here we show that single-locus changes affecting biofilm formation phenotypes in Bacillus subtilis modify community structure to the same extent as loss of an apex predator and even to a greater extent than loss of B. subtilis itself. These results, from experimentally manipulated multitrophic microcosm assemblages, demonstrate that bacterial social traits are key modulators of the structure of their communities. Moreover, they show that intraspecific genetic variability can be as important as strong trophic interactions in determining community dynamics. Microevolution may therefore be as important as species extinctions in shaping the response of microbial communities to environmental change.
Previous trials comparing carotid artery stenting (CAS) with carotid endarterectomy have shown that the former can increase the stroke rate. However, in the last years, because of the improvements either of the technique or the improvement of the stents and embolic protection devices (EPD), CAS has become a very competitive procedure. In this study, we tried to assess the feasibility and the safety of using double EPD (proximal and distal) in high-risk patients.

We collected data about all consecutive patients with carotid artery stenosis who underwent CAS and compared clinical and procedural characteristics as well as immediate and 30-day outcomes between the use of double vs. single EPD.

Between November 2007 and August 2014, 294 patients underwent CAS. In 35 of them (11.9%) double EPD was used. In comparison with the patients treated with single EPD, those with double EPD presented more with acute carotid syndrome (recurrent TIAs < 48 hr, minor stroke < 14 days) and with complex plaque (79.4 vs. Tetrazolium Red chemical structure 33.6%, P < 0.0001). There was no difference between the 2 groups in primary success (100 vs. 99.6%, P = 0.16) and in 30-days major complications death (0 vs. 0.8%, P = 0.6), major stroke (0 vs. 0.8%, P = 0.42), and minor stroke (0 vs 1.1%, P = 0.66).

In our experience, in high-risk patients with high-risk lesions, the use of double EPD (proximal and distal) is safe and effective in minimizing the risk of cerebral embolization, but, to validate such a technique in wide range of patients, further studies are warranted.
