Intranasal Calcitriol Accelerates Improvement of Sinonasal Inflammation and Olfactory Impairment in Mice After Cessation of Chronic Cigarette-Smoke Exposure.

Rationale: Smoking has been shown to be associated with circulating deficiencies in 25(OH)D3 and reduced sinonasal tissue levels of the active form of vitamin D, 1,25(OH)2D3. Given vitamin D's ability to reduce inflammation, we sought to examine if intranasal (IN) delivery of calcitriol [clinical analog of 1,25(OH)2D3] could reduce inflammation and improve disease severity in a murine model of chronic cigarette smoke-induced sinonasal inflammation (CS-SI).

Methods: Mice were exposed to CS 5 h/day, 5 days/week for 9 months, and then began IN calcitriol three times per week for 4 weeks.

Type 2 biomarkers in olfactory cleft mucus correlate with SNOT-22 in chronic rhinosinusitis independent of nasal polyp status.

Background: Quantitative mucus cytokine analysis to examine the sinonasal microenvironment may bridge the gap between patient-reported outcome measures (PROMs) and empirical measures of inflammation in patients with chronic rhinosinusitis (CRS).

Objective: Investigate the correlation between mucus cytokine levels and Sino-Nasal Outcome Test (SNOT-22) scores, including individual subdomains.

Methods: Patients with CRS were prospectively recruited between 2016 and 2021 into a multi-institutional observational study.

Meal replacement therapy for obesity and diabetes remission: efficacy assessment and considerations of barriers and facilitators to adherence among U.S. individuals with low economic resources.

Individuals in the United States with lower economic resources face a disproportionate burden of obesity and co-morbid conditions. This review summarizes the efficacy of MR programs for the treatment of obesity and diabetes and alerts clinicians to potential barriers and facilitators to the uptake of such programs so they may tailor their prescriptive approach. Implementation of effective behavioral and lifestyle interventions for obesity and diabetes in low-income settings is fraught with barriers and under-studied.

Integrating fire safety into bridge design is essential for resilient infrastructure.

The frequent occurrences of bridge fires and the substantial disruptions and direct/indirect economic losses resulting from these events highlight the immediate need for effective fire-safety-oriented design of new bridges and retrofit approaches for vulnerable existing bridges. In this Perspective, we discuss why a holistic engineering approach integrating innovative fire analysis methods and structural design/retrofit strategies into multi-hazard and future-oriented risk modeling frameworks represents the way forward to more sustainable and resilient infrastructure in an uncertain and rapidly changing built environment.

Observation of Medium-Induced Yield Enhancement and Acoplanarity Broadening of Low-p_{T} Jets from Measurements in pp and Central Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions.

Photoproduction of K^{+}K^{-} Pairs in Ultraperipheral Collisions.

K^{+}K^{-} pairs may be produced in photonuclear collisions, either from the decays of photoproduced ϕ(1020) mesons or directly as nonresonant K^{+}K^{-} pairs. Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.

ψ(2S) Suppression in Pb-Pb Collisions at the LHC.

The production of the ψ(2S) charmonium state was measured with ALICE in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV, in the dimuon decay channel. A significant signal was observed for the first time at LHC energies down to zero transverse momentum, at forward rapidity (2.

Pathways from research to sustainable development: Insights from ten research projects in sustainability and resilience.

Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produced during research projects into successful knowledge application; (ii) scaling up knowledge in time when research projects are short-term and potential impacts are long-term; and (iii) scaling up knowledge across space, from local research sites to larger-scale or even global impact. Some potential pathways for funding agencies to overcome these challenges include providing targeted prolonged funding for dissemination and outreach, and facilitating collaboration and coordination across different sites, research teams, and partner organizations.

Microbial sensor variation across biogeochemical conditions in the terrestrial deep subsurface.

Microbes can be found in abundance many kilometers underground. While microbial metabolic capabilities have been examined across different geochemical settings, it remains unclear how changes in subsurface niches affect microbial needs to sense and respond to their environment. To address this question, we examined how microbial extracellular sensor systems vary with environmental conditions across metagenomes at different Deep Mine Microbial Observatory (DeMMO) subsurface sites.

Measurement of the Lifetime and Λ Separation Energy of _{Λ}^{3}H.

The most precise measurements to date of the _{Λ}^{3}H lifetime τ and Λ separation energy B_{Λ} are obtained using the data sample of Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV collected by ALICE at the LHC. The _{Λ}^{3}H is reconstructed via its charged two-body mesonic decay channel (_{Λ}^{3}H→^{3}He+π^{-} and the charge-conjugate process).

Enhanced Deuteron Coalescence Probability in Jets.

The transverse-momentum (p_{T}) spectra and coalescence parameters B_{2} of (anti)deuterons are measured in p-p collisions at sqrt[s]=13  TeV for the first time in and out of jets. In this measurement, the direction of the leading particle with the highest p_{T} in the event (p_{T}^{lead}>5  GeV/c) is used as an approximation for the jet axis. The event is consequently divided into three azimuthal regions, and the jet signal is obtained as the difference between the toward region, that contains jet fragmentation products in addition to the underlying event (UE), and the transverse region, which is dominated by the UE.

Measurement of the J/ψ Polarization with Respect to the Event Plane in Pb-Pb Collisions at the LHC.

We study the polarization of inclusive J/ψ produced in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV at the LHC in the dimuon channel, via the measurement of the angular distribution of its decay products. We perform the study in the rapidity region 2.

All chronic rhinosinusitis endotype clusters demonstrate improvement in patient-reported and clinical outcome measures after endoscopic sinus surgery.

Background: It is unclear whether chronic rhinosinusitis (CRS) endotypes show a differential response to endoscopic sinus surgery (ESS). We explored patient mucous inflammatory cytokine expression and associations with patient-reported and clinically measured post-operative outcome measures.

Methods: Patients with CRS were prospectively recruited between 2016 and 2021 into a national multicenter, observational study.

Objectives: To describe the rare presentation, imaging and histological findings, and treatments in patients with IgG4-related disease (IgG4-RD) and diagnostic pitfalls and difficulties.

Methods: Cases of sinonasal IgG4-RD were retrieved, and clinicopathological features were reviewed.

Results: Seven cases of sinonasal IgG4-RD were identified over an 11-year period, including four males and three females, with an age range of 19-66 years (median 58 years).

Label compliance for ingredient verification: regulations, approaches, and trends for testing botanical products marketed for "immune health" in the United States.

During the COVID-19 pandemic, the botanical product market saw a consumer interest increase in immune health supplements. While data are currently insufficient to support public health guidance for using foods and dietary supplements to prevent or treat COVID-19 and other immune disorders, consumer surveys indicate that immune support is the second-most cited reason for supplement use in the United States. Meanwhile, consumers showed increased attention to dietary supplement ingredient labels, especially concerning authenticity and ingredient claims.

Single session therapy in pediatric healthcare: the value of adopting a strengths-based approach for families living with neurological disorders.

Background: Pediatric patients with neurological disorders often require lifelong management of symptoms and behaviours that can result in enduring emotional burden, stress and impacted health-related quality of life. Single session therapy (SST) draws upon patients' existing skills and knowledge and has emerged as a therapeutic approach to address pediatric patient and family needs in a timely manner. This study aimed to assess the clinical effectiveness of SST for pediatric patients with neurological disorders and their families, considering self-efficacy, distress, anxiety, therapeutic alliance and client satisfaction, as well as perceptions of whether SST met their pressing needs.

Utilization of Nasal Mucus to Investigate the Pathophysiology of Chronic Rhinosinusitis.

Background: Nasal mucus is proving to be a useful means by which to study the pathogenesis of chronic rhinosinusitis (CRS). Given the increase in publications examining nasal mucus and the lack of a review on this topic, we will focus on this noninvasive approach to studying CRS. Particular attention will be drawn towards inflammatory cytokines and biomarkers and their influence on disease severity.

Hypertriton Production in p-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The study of nuclei and antinuclei production has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. The first measurement of the production of _{Λ}^{3}H in p-Pb collisions at sqrt[s_{NN}]=5.02  TeV is presented in this Letter.

Role of C3a as a Novel Regulator of 25(OH)D to 1α,25-Dihydroxyvitamin D Metabolism in Upper Airway Epithelial Cells.

In patients with chronic rhinosinusitis with nasal polyps, primary human sinonasal epithelial cell (HSNEC) 1α-hydroxylase levels are reduced, as is their ability to metabolize 25-hydroxycholecalciferol [25(OH)D] to its active metabolite, 1α,25-dihydroxyvitamin D [1,25(OH)D]. In this study, we sought to identify the factor responsible for the regulation of HSNEC metabolism of 25(OH)D, focusing on C3 and C3a. Multiple inhaled irritants trigger the release of complement components, C3 and C3a, leading to suppression of 1α-hydroxylase levels in HSNECs.
