In this review, we summarize the role of TRP channels in chemical threat agents-induced pulmonary injuries and how these channels may serve as medical countermeasure targets for broader indications.Injury of the skin from exposure to toxic chemicals leads to the release of inflammatory mediators and the recruitment of immune cells. Nitrogen mustard (NM) and other alkylating agents cause severe cutaneous damage for which there are limited treatment options. Here, we show that combined treatment of vitamin D3 (VD3) and spironolactone (SP), a mineralocorticoid receptor antagonist, significantly improves the resolution of inflammation and accelerates wound healing after NM exposure. SP enhanced the inhibitory effect of VD3 on nuclear factor-kB activity. Combined treatment of NM-exposed mice with VD3 and SP synergistically inhibited the expression of iNOS in the skin and decreased the expression of matrix metallopeptidase-9, C-C motif chemokine ligand 2, interleukin (IL)-1α, and IL-1β. The combined treatment decreased the number of local proinflammatory M1 macrophages resulting in an increase in the M2/M1 ratio in the wound microenvironment. Apoptosis was also decreased in the skin after combined treatment. Together, this creates a proresolution state, resulting in more rapid wound closure. see more Combined VD3 and SP treatment is effective in modulating the immune response and activating anti-inflammatory pathways in macrophages to facilitate tissue repair. Altogether, these data demonstrate that VD3 and SP may constitute an effective treatment regimen to improve wound healing after NM or other skin chemical injury.
The aim of this study was to evaluate neurocognitive outcome at 24months of corrected age after less invasive surfactant application (LISA) in preterm infants born at 23-26weeks of gestational age.

Surviving participants of a LISA trial conducted in 13 German level III neonatal intensive care units were reviewed for assessment of developmental outcome, hearing and vision problems, growth and rehospitalisation days. Maternal depression, breastfeeding rates and socio-economic factors were evaluated as potentially confounding factors.

In total, 156/182 infants took part in the study, 78 had received surfactant via LISA and 78 via endotracheal intubation. 22% of LISA infants compared to 42% of intubated infants had a psychomotor development index (PDI) <70 (0.012). A significant difference in mental development index (MDI) was observed in the stratum of more mature infants (25 and 26weeks of GA). For this group, MDI<70 was observed in 4% of LISA infants vs 21% of intubated infants (P=0.008).

At 24months of age, the LISA-treated infants scored less often PDI<70 and had similar results in MDI. Infants born at 25 and 26weeks treated with LISA had lower rates of severe disability. LISA is safe and may be superior.

The main objective was to determine the trajectory of instrumental activities of daily living (iADL) decline in persons with mild cognitive impairment (MCI) who progressed towards dementia relative to persons with MCI who remained stable.

At study entry, 121 participants met criteria for MCI. Based on the follow-up, 47 participants later converted to dementia and were identified as progressors. Sixteen participants, identified as decliners, presented a significant cognitive decline but did not reach the criteria for dementia within the study timeframe. Stable MCI remained cognitively stable during the 5-year follow-up; n = 58. Participants completed a yearly assessment using clinical tests/questionnaires, neuropsychological measures, and functional autonomy assessment until they met criteria for dementia. The average number of months for the follow-up was 34.

Many years of stable performance followed by an accelerated decline just prior to diagnosis, was observed for complex activities for progressors. No change was found for stable MCI and a gradual linear decline characterized decliners. The housekeeping-related activities component showed a linear decline in progressors and did not change in stable and decliner MCI. We found a predictive model that includes significant predictors of dementia conversion with a high diagnostic accuracy the following year (area under the curve = 0.94 [95% confidence level; lower bound 0.87, upper bound 1]).

It is critical to assess iADL that reflect complex activities in the evaluation of MCI individuals as their impairment, combined with change on cognitive markers, indicates a higher risk of dementia progression 1 or 2 years later.

Herbal supplements and particularly multi-ingredient products have become increasingly common causes of acute liver injury. Green tea is a frequent component in implicated products, but its role in liver injury is controversial.

Among 1414 patients enrolled in the U.S. Drug Induced Liver Injury Network who underwent formal causality assessment, 40 cases (3%) were attributed to green tea, 202 to dietary supplements without green tea, and 1142 to conventional drugs. The clinical features of green tea cases and representation of HLA class I and II alleles in cases and control groups were analyzed in detail.

Patients with green tea-associated liver injury ranged in age from 17 to 69 years (median = 40) and developed symptoms 15 to 448 days (median = 72) after starting the implicated agent. The liver injury was typically hepatocellular (95%) with marked serum aminotransferase elevations and only modest increases in alkaline phosphatase. Most patients were jaundiced (83%) and symptomatic (88%). The course was judged as severe in 14 patients (35%), necessitating liver transplantation in 3 (8%), but rarely resulting in chronic injury (3%). In three instances, injury recurred upon re-exposure to green tea with similar clinical features but shorter time to onset. HLA typing revealed a high prevalence of HLA-B*3501, found in 72% (95% CI 58% to 87%) of green tea cases but only 15% (95% CI 10% to 20%) caused by other supplements and 12% (95% CI 10% to 14%) attributed to drugs, the latter rate being similar to population controls (95% CI 11% 10.5% to 11.5%).

Green tea-related liver injury has distinctive clinical features and close association with HLA-B*3501 suggesting that it is idiosyncratic and immune-mediated.
