Abstract
PURPOSE To investigate the association of food insecurity with overall and disease-specific mortality among US cancer survivors. METHODS Data from the National Health and Nutrition Examination Survey (NHANES 1999-2018) were used to examine the impact of food insecurity on mortality risks among cancer survivors in the US. Study participants aged ≥ 20 years who had a history of cancer and completed the Adult Food Security Survey Module were included. Mortality data [all-cause, cancer, and cardiovascular (CVD) specific] through December 31, 2019 were obtained through linkage to the National Death Index. Using multivariable Cox proportional hazard regression, hazard ratios of mortality based on food security status were estimated. RESULTS Among 5032 cancer survivors (mean age 62.5 years; 58.0% women; 86.2% non-Hispanic White), 596 (8.8%) reported food insecurity. Overall, 1913 deaths occurred (609 cancer deaths and 420 CVD deaths) during the median follow-up of 6.8 years. After adjusting for age, food insecurity was associated with a higher risk of overall (HR = 1.93; 95% CI = 1.56-2.39), CVD-specific (HR = 1.95; 95% CI = 1.24-3.05), and cancer-specific (HR = 1.70; 95% CI = 1.20-2.42) mortality (P < 0.001). However, after adjusting for socioeconomic characteristics and health-related factors (physical activity, diet quality measured by healthy eating index), the association between food insecurity and overall mortality was no longer statistically significant. CONCLUSIONS Food insecurity was associated with a greater risk of overall mortality among cancer survivors. Further studies are needed to confirm these findings and evaluate whether the observed association represents a causal phenomenon and, if so, whether the effect is modifiable with food assistance programs.

Abstract
Media exposed to atmospheric pressure plasma (APP) produce reactive oxygen and nitrogen species (RONS), with hydrogen peroxide (H2O2), nitrite (NO2-), and nitrate (NO3-) being among the most detected species due to their relatively long lifetime. In this study, a standardized microwave-excited (ME) APP jet (APPJ) source was employed to produce gaseous RONS to treat liquid samples. The source was a commercially available plasma jet, which generated argon plasma utilizing a coaxial transmission line resonator at the operating frequency of 2.45 GHz. An ultraviolet-visible spectrophotometer was used to measure the concentrations of H2O2 and NO3- in plasma-activated media (PAM). Three different types of media (deionized water, Hank's balanced salt solution, and cell culture solution Dulbecco's modified eagles medium [DMEM]) were utilized as liquid samples. Among these media, the plasma-treated DMEM was observed to have the highest levels of H2O2 and NO3-. Subsequently, the feasibility of using argon ME-APPJ-activated DMEM (PAM) as an adjuvant to enhance the therapeutic effects of cisplatin on human bladder cancer cells (T-24) was investigated. Various cancer cell lines, including T-24 cells, treated with PAM were observed in vitro for changes in cell viability using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. A viability reduction was detected in the various cancer cells after incubation in PAM. Furthermore, the study's results revealed that PAM was effective against cisplatin-resistant T-24 cells in vitro. In addition, a possible connection between HER expression and cell viability was sketched.

Abstract
Context Systemic inflammation is associated with cardiovascular morbidity and mortality. Since inflammation is not screened in the population, the prevalence, particularly among individuals with undiagnosed cardiometabolic disease, is unclear. Objective To assess the prevalence of elevated inflammation using high sensitivity C-reactive protein (hs-CRP) (>0.30 mg/dL) in adults with no cardiometabolic disease, undiagnosed disease and diagnosed disease. Methods We conducted a cross-sectional analysis of the 2015-2020 National Health and Nutrition Examination Survey which allows for population estimates of the US population. Adults > = 20 years old were included. HsCRP levels >0.30 mg/dL represented inflammation. Individuals were classified into disease defined as having one or more of the following: diagnosed disease--diabetes, hypertension, hyperlipidemia, or obesity by diagnosis; undiagnosed disease (self-report of no doctor diagnosis but positive biomarker); no disease. Results 12,946 unweighted individuals representing 315,354,183 adults in the US population were assessed. The proportion of adults with systemic inflammation is 34.63%. The proportion of individuals aged 20 years and older with no disease, undiagnosed disease and diagnosed disease and inflammation was 15.1, 29.1 and 41.8%, respectively. When stratifying by race/ethnicity among individuals with elevated inflammation Non-Hispanic Black people have the highest prevalence (50.35%) in individuals with diagnosed disease followed by Hispanics (46.13%) and Non-Hispanic White people (40.15%) (p < 0.01). In logistic regressions adjusted for sociodemographic variables, individuals with undiagnosed cardiometabolic disease have an increased risk of elevated inflammation as measured by CRP (OR 2.38; 95%CI = 1.90-2.99). Conclusion In conclusion, a substantial proportion of the adult population, particularly minority and low socioeconomic populations, have elevated inflammation. Systemic inflammation may be a potential focus for disease prevention and disease progression in primary care.

Abstract
Introduction Telehealth has been widely promoted and adopted at multiple levels in the U.S. healthcare system during the COVID-19 pandemic. However, this rapid expansion of telehealth services may have further exacerbated health inequities among marginalized groups. Methods Using the 2020 National Health Interview Survey, this study compared patterns of telehealth use between people with functional disabilities and people without disabilities during the first year of the pandemic. Results In the multivariable-adjusted logistic regression models, respondents with moderate disabilities were significantly more likely to report telehealth use, not pandemic related (OR=1.25, 95% CI=1.03, 1.52) and telehealth use, pandemic related (OR=1.43, 95% CI=1.28, 1.60) than people without disabilities. Similarly, respondents with severe disabilities were significantly more likely to report telehealth use, not pandemic related (OR=1.46, 95% CI=1.07, 2.00) and telehealth use, pandemic related (OR=2.06, 95% CI=1.72, 2.46). In addition, telehealth use varied by the number of limitations and disability type. Conclusions People with functional disabilities were more likely to report telehealth use than people without disabilities. Furthermore, these associations strengthened with increasing disability severity and number of limitations while varying by disability type. Additional studies are warranted to explore ways of providing patient-centered telehealth to responsively meet various healthcare needs of people with functional disabilities and improve their health outcomes.

Abstract
BACKGROUND AND OBJECTIVES Implementing a structured activity to encourage exercise in children may be a strategy with benefits. We evaluated pulmonary function in elementary school children participating in a school-based exercise program called The Daily Mile. METHODS During the fall semester, we implemented The Daily Mile program in one elementary school and compared pulmonary function in children in the intervention school pre- and postintervention to children in a control school in the same community. The primary outcomes were forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1% (the FEV1/FVC ratio). RESULTS The children in the control school showed no significant change in FEV1% during the semester (P=.06). On the other hand, children in the intervention school showed a significant improvement in FEV1% during the same semester (P=.001). This effect was consistent even when stratifying by asthma and sports participation. CONCLUSIONS The Daily Mile has benefits for pulmonary function in children. Although family physicians should continue to encourage their patients to have a healthy lifestyle, a more effective approach may be to encourage schools to adopt a program that teachers oversee and administer in a structured way.

Abstract
Evidence suggests that the human respiratory tract, as with the gastrointestinal tract, has evolved to its current state in association with commensal microbes. However, little is known about how the airway microbiome affects the development of airway immune system. Here, we uncover a previously unidentified mode of interaction between host airway immunity and a unique strain (AIT01) of Staphylococcus epidermidis, a predominant species of the nasal microbiome. Intranasal administration of AIT01 increased the population of neutrophils and monocytes in mouse lungs. The recruitment of these immune cells resulted in the protection of the murine host against infection by Pseudomonas aeruginosa, a pathogenic bacterium. Interestingly, an AIT01-secreted protein identified as GAPDH, a well-known bacterial moonlighting protein, mediated this protective effect. Intranasal delivery of the purified GAPDH conferred significant resistance against other Gram-negative pathogens (Klebsiella pneumoniae and Acinetobacter baumannii) and influenza A virus. Our findings demonstrate the potential of a native nasal microbe and its secretory protein to enhance innate immune defense against airway infections. These results offer a promising preventive measure, particularly relevant in the context of global pandemics.

Abstract
BACKGROUND Allergic rhinitis (AR) is characterized by airway inflammation in nasal mucosa from inhaled allergens and interleukin (IL)-33 is the potent inducer of Th2 inflammation in allergic nasal epithelium. Staphylococcus epidermidis is one of the most abundant colonizers of the healthy human nasal mucosa and might impact the allergen-induced inflammatory responses in the nasal epithelium. Thus, we sought to characterize the mechanism of S. epidermidis regulating Th2 inflammation and IL-33 production in AR nasal mucosa. RESULTS The AR symptoms were alleviated and eosinophilic infiltration, serum IgE levels, and Th2 cytokines were significantly decreased in OVA-sensitized AR mice in response to human nasal commensal S. epidermidis. The inoculation of S. epidermidis to normal human nasal epithelial cells reduced IL-33 and GATA3 transcriptions and also reduced IL-33 and GATA3 expression in AR nasal epithelial (ARNE) cells and the nasal mucosa of AR mice. Our data exhibited that the cellular necroptosis of ARNE cells might be involved in IL-33 production and inoculation of S. epidermidis decreased the phosphorylation of necroptosis enzymes in ARNE cells, which was related to the reduction of IL-33 production. CONCLUSIONS We present that human nasal commensal S. epidermidis reduces allergic inflammation by suppressing IL-33 production in nasal epithelium. Our findings indicate that S. epidermidis serves a role in blocking allergen-induced cellular necroptosis in allergic nasal epithelium which might be a key mechanism of reduction of IL-33 and Th2 inflammation.

Abstract
BACKGROUND Undiagnosed Type 2 diabetes (T2D) has been associated with advanced stage cancer at diagnosis, higher mortality, and lower long-term all-cause survival. This was a RCT pilot study to examine the feasibility of a nurse-led T2D intervention for adults with newly diagnosed cancer (≤3 months), and T2D, undiagnosed or untreated with medication, conducted at an outpatient oncology clinic affiliated with a large academic institution. METHODS Participants needed to meet the eligibility criteria including a HbA1c level between 6.5% and 9.9%. Randomization was 1:1 to a 3-month intervention that consisted of nursing-led diabetes education and immediate initiation of metformin versus referral to primary care for usual care (control). RESULTS Three hundred and seventy nine patients were screened using EHR, 55 agreed to participate, and 3 had eligible HbA1c levels and were randomized in the study. Primary reasons for study exclusion included life expectancy ≤2 years (16.9%), current use or inability to tolerate metformin (14.8%), and abnormal labs that contraindicated metformin use (13.9%). CONCLUSION This study was not feasible due to recruitment inefficiencies, but acceptable to all who qualified.

Abstract
BACKGROUND Vaccinium bracteatum Thunb. leaves (VBL) are used in traditional herbal medicines to treat various biological diseases. p-coumaric acid (CA), the main active component of VBL, has neuroprotective effects against corticosterone-induced damage in vitro. However, the effects of CA on immobility induced by chronic restraint stress (CRS) in a mouse model and 5-HT receptor activity have not been investigated. HYPOTHESIS/PURPOSE We investigated the antagonistic effects of VBL, NET-D1602, and the three components of Gαs protein-coupled 5-HT receptors. Additionally, we identified the effects and mechanism of action of CA, the active component of NET-D1602, in the CRS-exposed model. METHODS For in vitro analyses, we used 1321N1 cells stably expressing human 5-HT6 receptors and CHO-K1 expressing human 5-HT4 or 5-HT7 receptors cell lines to study the mechanism of action. For in vivo analyses, CRS-exposed mice were orally administered CA (10, 50, or 100 mg/kg) daily for 21 consecutive days. The effects of CA were analyzed by assessing behavioral changes using a forced swim test (FST), measuring levels of hypothalamic-pituitary-adrenal (HPA) axis-related hormones in ntial therapeutic effects as 5-HT6 receptor antagonists for neurodegenerative diseases and depressioserum, and acetylcholinesterase (AChE), monoamines, including 5-HT, dopamine, and norepinephrine, using enzyme-linked immunosorbent assay kits. The underlying molecular mechanisms of the serotonin transporter (SERT), monoamine oxidase A (MAO-A), and extracellular signal-regulated kinase (ERK)/protein kinase B (Akt)/mTORC1 signaling were detected using western blotting. RESULTS CA was confirmed to be an active component in the antagonistic effects of NET-D1602 on 5-HT6 receptor activity through decreases in cAMP and ERK1/2 phosphorylation. Moreover, CRS-exposed mice treated with CA showed a significantly reduced immobility time in the FST. CA also significantly decreased corticosterone, corticotropin-releasing hormone (CRH), and adrenocorticotropic hormone (ACTH) levels. CA enhanced 5-HT, dopamine, and norepinephrine levels in the hippocampus (HC) and prefrontal cortex (PFC) but decreased MAO-A and SERT protein levels. Similarly, CA significantly upregulated the ERK, Ca2+/calmodulin-dependent protein kinase II (CaMKII), Akt/mTOR/p70S6K/S6 signaling pathways in both HC and the PFC. CONCLUSION CA contained in NET-D1602 may play the antidepressant effects against CRS-induced depression-like mechanism and the selective antagonist effect of 5-HT6 receptor.

Abstract
BACKGROUND l-Leucine powder (LP) was added to green Robusta coffee beans in order to reduce the difference in flavour between Robusta and Arabica coffee. l-Leucine was selected as an additive based on the Maillard reaction. The pre-treatment method conducted in this study was a short soaking (M1) or spraying procedure (M2), then LP was added at varying levels up to 3% (w/w, 30 g kg-1 ). All samples were roasted (240 °C for 15 min) and extracted using an espresso machine. Volatile compounds were analysed by solid-phase microextraction-gas chromatography-mass selective detection. RESULTS Thirty volatile compounds (six pyrroles, eight pyrazines, three phenols, nine furans, two ketones, two aldehydes) were analysed. In 15 coffee samples, the levels of total volatile compounds (based on peak area ratios) ranged from 8.9 (M1-1) to 15. Non-treated Robusta had higher levels of bitter aroma compounds than Arabica coffee, and Robusta coffee had lower levels of bitter aroma compounds when pre-treated with LP. The sum of bitter volatiles (phenols, pyrroles, pyrazines) was lowest in M1-5 (3% LP), M2-1 (1% LP; both dried at 50 °C for 15 min) and M2-7 (3% LP, dried at 70 °C for 15 min) compared with non-treated Robusta (P < 0.05). CONCLUSION From the results of this study it can be shown that pre-treatment with LP can improve the flavour of Robusta. © 2023 Society of Chemical Industry.

Abstract
BACKGROUND Literature shows that limited English proficiency (LEP) influences individual healthcare-seeking behaviors. The Asian population is the fastest-growing racial/ethnic group in the US, and approximately 50% of foreign-born Asians are estimated to live with LEP. OBJECTIVE To examine associations of LEP and patient-provider language concordance (PPLC) with evidence-based cancer screening utilization for cervical, breast, and colorectal cancers among Asian American adults. METHODS We obtained LEP, PPLC, and up-to-date status on the three types of cancer screening from a nationally representative sample of Asian Americans aged ≥ 18 years in the 2010-2016 and 2018 Medical Expenditure Panel Surveys. We used multivariable logistic regression models with recommended survey weighting to examine associations of LEP and PPLC with the cancer screening uptake based on USPSTF guidelines. RESULTS The study population comprised 8953 respondents, representing 8.17 million Asian American adults. Overall, 11.9% of respondents experienced LEP; of those with LEP, 20% were with PPLC. In multivariable models, compared to respondents without LEP, respondents with LEP and without PPLC were significantly less likely to report up-to-date status on breast (OR = 0.44; 95% CI: 0.26-0.76), cervical (OR = 0.44; 95% CI: 0.26-0.75), or colorectal cancer screening (OR = 0.46; 95% CI: 0.26-0.80). However, these differences were not detected in respondents with LEP and with PPLC. CONCLUSION LEP is associated with lower up-to-date status on cancer screening among Asian Americans, while PPLC seems to moderate this association. These findings suggest the enhancement for language-appropriate and culturally competent healthcare for Asian Americans with LEP, which helps accommodate their communication needs and promotes cancer screening.

Abstract
Cadmium zinc telluride (CZT) has been actively researched and developed by researchers in various fields. In medical applications, especially photon-counting, CZT enables improved image quality, multi-material decomposition, and improved dose efficiency. Moreover, band gap engineering and selenium addition on CZT improved electrical, spectroscopic and structural properties, thereby supporting performance of CZT as a photon-counting detector. In this study, it is shown that Cd0.875Zn0.125Te0.98Se0.02 (CZTS) shows sufficient performance without loss of detection efficiency. We carried out a study involving the application of this CZTS on calculating bone mineral density (BMD) values, because this application has a novelty of new material for BMD sensor which follows the CdTe- or CdZnTe- based BMD detector. Anatomical images from different energy bins contained different information of attenuation although the images were taken in the same region at the same time. Moreover, calculated BMD values had a proper tendency depending on the amount of bone in that region. The final BMD value was 1.1972 g/cm2, which is close to the real value of 1.2 g/cm2. The introduction with a bone filter and a smaller pixel size will improve the accuracy and precision of photon-counting CZTS detectors for measuring BMD values. However, in this study the CZTS showed the feasibility that a photon-counting CZTS detector can help the measurement of BMD values and the diagnosis of osteoporosis.

Abstract
BACKGROUND AND OBJECTIVES Demand for geriatric care is increasing due to aging population. Trends in maintaining certification in geriatrics are unreported. Our objective was to describe the historic trend of family physicians who certified in geriatric medicine (FPs-GM) since 1988 and to assess differences in practice patterns between FPs-GM and family physicians (FPs). METHODS We performed a retrospective descriptive study using administrative data collected by the American Board of Family Medicine (ABFM). The study population was family physicians registering to continue their ABFM certification from 2017 to 2019. Medicare public use billing data was linked to ABFM administrative data on certification history. We used univariate analysis for descriptive analysis and logistic regression to identify contributors of recertification in geriatrics. RESULTS We identified a total of 3,207 FPs-GM between 1988 and 2019. More than half maintained GM certification since 2009 (57%), with male gender, White race, and urban practice associated with maintaining GM certification; 61% of their patients were older adults. FPs-GM were more likely to be in an academic practice setting with nearly half (53%) also practicing in hospitals or nursing homes. In the adjusted regression model, younger FPs or FPs who treat more older patients were significantly more likely to be recertified in geriatrics whereas other demographics and practice characteristics were not significant. CONCLUSIONS Most FPs who recently earned GM certification tended to retain certification since the required accredited fellowship started in 1995.

Abstract
Introduction The innate immune responses of upper airway could further our understanding toward antiviral strategies against SARS-CoV-2. We characterize the potential of interferon (IFN)-λ as an innate immune inducer for the rapid clearance of SARS-CoV-2 in the lung and the therapeutic efficacy of intranasal inoculation of IFN-λ to resolve acute lung infection. Methods Syrian golden hamsters were infected with SARS-CoV-2 and the dynamics of SARS-CoV-2 infection depending on IFN-λ inoculation were tested. Results SARS-CoV-2-infected Syrian golden hamsters exhibited a significant decrease in body weight and high viral mRNA level at 3 days post-infection (dpi). Although viral replication was reduced completely from 7 dpi, the pathologic findings remained prominent until 14 dpi in the lung of hamsters. The transcription of IFN-λ was significantly induced in response to SARS-CoV-2 infection with the increase of IFN-stimulated genes. Intranasal inoculation of IFN-λ restricted SARS-CoV-2 replication in the lungs of infected completely from 3 dpi with markedly reduction of inflammatory cytokines. The transcriptional phenotypes were altered to the direction of damage repair and tissue remodeling in the lungs of SARS-CoV-2-infected hamsters following intranasal inoculation of IFN-λ, which improved SARS-CoV-2-caused lung damage. Conclusion Collectively, our findings suggest that IFN-λ might be a potent innate immune inducer in the lung and intranasal inoculation of IFN-λ resolves SARS-CoV-2 infection with rapid viral clearance and improvement of lung damage.

Abstract
PURPOSE This study investigated the clinical implications of neutrophil extracellular trap (NET) formation (NETosis) and eosinophil extracellular trap (EET) formation (EETosis) regarding refractoriness in chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP). METHODS Nasal polyp specimens were obtained from 117 patients with CRSwNP who received endoscopic sinus surgery. Disease control status at postoperative 1 year was assessed. Refractory cases were defined as partly controlled or uncontrolled cases according to the EPOS 2020 guidelines. NETosis and EETosis were evaluated through immunofluorescence staining (citrullinated histone H3-human neutrophil elastase and citrullinated histone-galectin-10, respectively) followed by manual counting. The z-score of NET and EET counts was used to define the following four groups: low extracellular trap formation (ETosis), NETosis-predominant, EETosis-predominant, and high-ETosis. RESULTS The refractory and non-refractory groups showed significant differences in the tissue eosinophil count (P = 0.005) and EET count (P = 0.029). The tissue neutrophil count and the NET/neutrophil ratio were significantly different between the refractory and non-refractory groups of patients with neutrophilic CRS (P = 0.045, 0.031, respectively). Refractoriness significantly differed among the low-ETosis (30.77%), NETosis-predominant (47.83%), EETosis-predominant (56.67%), and high-ETosis (83.33%) groups (P = 0.005). CONCLUSIONS The results of this study suggest that tissue Eosinophilia and EETosis may play a prognostic role, primarily in CRSwNP and thattissue neutrophilia and NETosis can play as prognostic biomarkers in neutrophilic CRSwNP.

Abstract
Cancer is a major health problem in the U.S and type 2 diabetes mellitus (T2DM) is known to increase the risk for the development of many cancers. Metformin, a first-line therapy for treating T2DM, is increasingly being used for its anticancer effects; however, the literature is limited on the effect of metformin dose on overall survival in patients with stage IV cancer. Overall survival was defined as the time interval from the date of diagnosis to the last known follow-up or death from any cause. Subjects who were alive on December 31, 2016 were censored. In this cohort study we examined the relationship between metformin dose and overall survival in persons with both T2DM and stage IV lung, breast, colorectal, prostate, or pancreas cancers. We used a retrospective study design with Cox proportional hazards regression analysis of the 2007–2016 of the Surveillance Epidemiology and End Results-Medicare (SEER) dataset. Of the 7,725 patients, 2,981(38.5%) had been prescribed metformin. Patients who used metformin had significantly better overall survival in both unadjusted (Unadjusted HR, 0.73; 95% CI, 0.69–0.76; p < 0.001) and adjusted models (adjusted HR, 0.77; 95% CI, 0.73–0.81; p < 0.001). The overall survival between patients who took metformin with average daily dose ≥ 1000mg or < 1000mg were not statistically significant (aHR, 1.00; 95% CI, 0.93–1.08; p = 0.90). Metformin use regardless of dose is associated with increased overall survival in older adults with stage IV cancer.

Abstract
Background Adiposity and skeletal muscle levels assessed on computed tomography (CT) scans are prognostic indicators for patients with breast cancer. However, the intraindividual reliability of temporal changes in body composition assessed on opportunistic CT scans is unclear. Methods This retrospective study included 50 patients newly diagnosed with breast cancer who had archived CT scans pre- and postsurgery for breast cancer. The third lumbar CT image was segmented for areas of 3 types of adipose tissues and 5 different densities of skeletal muscles. Mean and percent changes in areas pre- vs postsurgery were compared using Wilcoxon signed rank tests. Intraclass correlation coefficients (ICCs) with 95% confidence intervals were assessed. A 2-sided P less than .05 was considered statistically significant. Results Mean (SD) age at diagnosis was 58.3 (12.5) years, and the interval between CT scans was 590.6 (536.8) days. Areas for body composition components were unchanged except for intermuscular adipose tissue (mean change = 1.45 cm2, 6.74% increase, P = .008) and very high-density muscle (mean change = −0.37 cm2, 11.08% decrease, P = .01) during the interval. There was strong intraindividual reliability in adipose tissue and skeletal muscle areas on pre- vs postsurgery scans overall (ICC = 0.763-0.998) and for scans collected 3 or less years apart (ICC = 0.802-0.999; 42 patients). Conclusions Although some body composition components may change after breast cancer surgery, CT scan assessments of body composition were reliable for a 3-year interval including the surgery. These findings inform measurement characteristics of body composition on opportunistic CT scans of patients undergoing surgery for breast cancer.

Abstract
Remarkable progress has recently been achieved to identify the biological function and potential value of novel therapeutic targets for the effective control of allergic asthma. Interferon (IFN)-λ has been suggested to restrict chronic inflammation in the lungs of asthmatic mice and we sought to determine the contribution of IFN-λ as an asthma therapeutic. We show that inhaled IFN-λ can restrict Th2 and Th17 inflammation in the lungs of asthmatic mice, accompanied with alteration of IL-10 secretion. BALB/C mice were used for an asthmatic mouse model with OVA. Recombinant IFN-λs (IFN-λ2: 2 μg, IFN-λ3: 2 μg) were inoculated into asthmatic mice after OVA challenge by intranasal delivery. Lungs of asthmatic mice were severely inflamed, with extensive inflammatory cell infiltration and increased goblet cell metaplasia with higher total lung resistance. Transcription of IL-4, IL-5, IL-13, and IL-17A was significantly higher until five days after the final OVA challenge. Asthmatic mice were administered recombinant IFN-λ via inhalation three times after the last challenge and the asthmatic mice showed improvement in lung histopathologic findings, and total lung resistance was maintained under normal range. IFN-λ inhalation exhibited significant decreases in Th2 and Th17 cytokine levels, and the populations of Th2 and Th17 cells were recovered from the lungs of asthmatic mice. Additionally, increase in IL-10 secretion from CD4 + Th cells population was observed in response to inhaled delivery of IFN-λ along with alterations in Th2 and Th17 cell-derived inflammation. Our findings show that inhaled delivery of IFN-λ can restrict airway inflammation in the lungs of asthmatic mice by controlling Th2- and Th17-mediated responses accompanied by regulation of IL-10 secretion even after asthma development.

Abstract
Plasma activated medium (PAM) was prepared by a bipolar microsecond-pulsed atmospheric pressure plasma jet (APPJ) array source and was utilized for cancer cell treatment. APPJ array-produced plasma were characterized. APPJ array treatment of three different solutions (deionized water (DW), HBSS (serum-free Hanks’ balanced salt solution), and DMEM (Dulbecco’s Modified Eagle Medium) + 10% FBS (fetal bovine serum)) were performed to induce the changes in the concentration of reactive oxygen and nitrogen species (RONS) as functions of the operating parameters. Human cervical cancer cells (HeLa) injected with plasma-treated media were investigated for changes in cell viability using MTT assay. It was observed that PAM-induced ROS can regulate the protein expression associated with mitochondria, and PAM causes apoptosis through Cyto C/JNK/p38 signaling on human cervical cancer cells.

Abstract
Abstract
Cancer and type 2 diabetes (T2DM) are common diseases that have serious health consequences. T2DM is known to increase the risk for the development of many of the most common cancers. Metformin, one of the most commonly used drugs to treat T2DM, is increasingly being used for its anticancer effects; however, the literature is limited on the effect of metformin dose on OS in patients with advanced cancer. We examined the relationship between metformin dose and OS in persons with both T2DM and stage IV lung, breast, colorectal, prostate, or pancreas cancers.
Methods: We used a retrospective study design with cox proportional hazards regression analysis of the 2007-2016 of the Surveillance Epidemiology and End Results-Medicare dataset.
Results: A total of 7,725 patients with T2DM and a least one targeted cancer was included in the analysis. Of those patients, 38.5% had been prescribed metformin. Patients who used metformin had significantly better OS in both unadjusted (Unadjusted HR, 0.73; 95% CI, 0.69-0.76; p < 0.001) and adjusted models (adjusted HR, 0.77; 95% CI, 0.73-0.81; p < 0.001). The OS between patients who took metformin with average daily dose ≥ 1000mg or < 1000mg were not statistically significant (aHR, 1.00; 95% CI, 0.93-1.08; p=0.90).
Conclusions: Metformin use, regardless of dose, increases OS in older adults with advanced cancer. Additionally, OS was not significantly different across race or ethnicity.

Abstract
Objective: Our previous studies showed an age-related increased prevalence of nasal polyps (NP) and reduced production of S100A8/9 in elderly patients with chronic rhinosinusitis with NP (CRSwNP). In this study, we investigated an unbiased age-related gene expression profile in CRSwNP subjects and healthy controls, and further identified the differences in their tissue remodeling. Methods: Microarrays using NP and uncinate tissues from health controls (elderly, age ≥65 vs. non-elderly, age 18-49) were performed, and differentially regulated genes were analyzed. Quantitative real-time PCR (qPCR), Immunostaining, Periodic acid-Schiff (PAS), trichrome staining, Western blot, and ELISA were performed for further investigation. Results: Microarrays identified differentially expressed genes according to disease and age; 278 in NP vs. controls, 75 in non-elderly NP vs. non-elderly controls, and 32 in elderly NP vs. elderly controls. qPCR confirmed that the PLAT gene was downregulated and the SERPINB2 gene upregulated in NP vs. controls. The serous glandular cell-derived antimicrobial protein/peptide-related genes such as BPIFB3, BPIFB2, LPO, and MUC7 were remarkably reduced in NP, regardless of age. SERPINE1 gene (plasminogen activator inhibitor-1, PAI-1) expression was significantly increased in elderly NP versus elderly controls. IHC and western blot confirmed significantly decreased production of MUC7 and LPO in NP versus controls. There was a trend of age-related reduction of submucosal gland cells in normal controls. Trichrome and immunofluorescence staining demonstrated an age-related increase of collagen and fibrin deposition in NP, consistent with increased PAI-1 production. Conclusion: This study demonstrated age-related differential glandular remodeling patterns and fibrosis in NP and normal controls. PAI-1 expression was significantly increased in elderly NP versus elderly controls, suggesting PAI-1 as a potential treatment target in elderly NP.

Abstract
Cold atmospheric plasma (CAP) that generates reactive oxygen species (ROS) has received considerable scientific attentions as a new type of anticancer. In particular, an indirect treatment method of inducing cancer cell death through plasma-activated medium (PAM), rather than direct plasma treatment has been well established. Although various cell death pathways such as apoptosis, necroptosis, and autophagy have been suggested to be involved in PAM-induced cell death, the involvement of ferroptosis, another type of cell death regulated by lipid ROS is largely unknown. This study reports, that PAM promotes cell death via ferroptosis in human lung cancer cells, and PAM increases intracellular and lipid ROS, thereby resulting in mitochondrial dysfunction. The treatment of cells with N-acetylcysteine, an ROS scavenging agent, or ferrostatin-1, a ferroptosis inhibitor, protects cells against PAM-induced cell death. Interestingly, ferroptosis suppressor protein 1 (FSP1) is downregulated upon PAM treatment. Furthermore, the treatment of cells with iFSP1, an inhibitor of FSP1, further enhances PAM-induced ferroptosis. Finally, this study demonstrates that PAM inhibits tumor growth in a xenograft model with an increase in 4-hydroxynoneal and PTGS2, a byproduct of lipid peroxidation, and a decrease in FSP1 expression. This study will provide new insights into the underlying mechanism and therapeutic strategies of PAM-mediated cancer treatment.

Abstract
Mutations in specific genes, including synuclein alpha (SNCA) that encodes the α-synuclein protein, are known to be risk factors for sporadic Parkinson's disease (PD), as well as critical factors for familial PD. In particular, A53T-mutated SNCA (A53T-SNCA) is a well-studied familial pathologic mutation in PD. However, techniques for deletion of the mutated SNCA gene in vivo have not been developed. Here, we used the CRISPR-Cas9 system to delete A53T-SNCA in vitro as well as in vivo. Adeno-associated virus carrying SaCas9-KKH with a single-guide RNA targeting A53T-SNCA significantly reduced A53T-SNCA expression levels in vitro. Furthermore, we tested its therapeutic potential in vivo in a viral A53T-SNCA-overexpressing rat model of PD. Gene deletion of A53T-SNCA significantly rescued the overexpression of α-synuclein, reactive microgliosis, dopaminergic neurodegeneration, and parkinsonian motor symptoms. Our findings propose CRISPR-Cas9 system as a potential prevention strategy for A53T-SNCA-specific PD.

Abstract
Teach-back method can help promote interactive communication between patients and
providers. However, the mechanism of how teach-back operates in routine care is
uninvestigated. Using pathway analysis, we explored the potential pathways of
patient teach-back to health outcomes among individuals with diabetes. Study
sample included 2901 US adults with diabetes ascertained from the 2011 to 2016
Longitudinal Medical Expenditure Panel Survey. Our pathway model analysis showed
that patient teach-back was associated with better interaction with providers,
shared decision-making, and receiving lifestyle advice. Teach-back had a direct
negative effect on condition-specific hospitalization and indirect negative
effects through lifestyle advice and diabetic complication. Teach-back method
may promote active interactions between patients and providers by creating an
opportunity to be more engaged in shared decision-making and receive additional
health advice from providers. These improvements seem to be associated with a
reduction in risks for complications and related hospitalization.

Abstract
INTRODUCTION Although research has analyzed the sociodemographic and socioeconomic risks for suicide, only recently has suicide risk for people with disabilities been examined. This study investigates the associations between disability and distinct suicide-related outcomes, including suicidal ideation, suicide planning, and suicide attempt. METHODS This nationally representative, cross-sectional study comprised secondary analyses of the 2015-2019 National Survey on Drug Use and Health conducted in 2020 (N=198,640, representing 229,556,289 U.S. adults). Disability status comprised the presence of any disability; hearing, vision, mobility, cognitive, complex activity, or ≥2 limitations; and 1, 2, 3, 4, or ≥5 limitations. Suicide-related outcomes in the past year included none, suicidal ideation only, suicide planning, and suicide attempt. Multivariable logistic regression was applied to estimate the AORs. RESULTS Overall, 19.8% reported any disability. Results showed that people with disabilities were significantly more likely than those without disabilities to report suicidal ideation (AOR=2.13, 95% CI=1.93, 2.36), suicide planning (AOR=2.66, 95% CI=2.27, 3.11), and suicide attempt (AOR=2.47, 95% CI=2.05, 2.98). Furthermore, individuals within each limitation count group were significantly more likely than people without disabilities to report suicide-related outcomes (p<0.001), with the largest magnitudes among those with ≥5 limitations for suicidal ideation (AOR=3.80, 95% CI=2.32, 6.23), suicide planning (AOR=6.45, 95% CI=3.52, 11.80), and suicide attempt (AOR=8.19, 95% CI=4.45, 15.07). CONCLUSIONS People with various types of functional disabilities had an elevated risk for suicide-related outcomes, compared with people without disabilities. The more limitations a person had progressively increased their risk. These findings call for focused attention to the mental health of people with disabilities, including suicide prevention efforts that accommodate their needs.

Abstract
High-resolution 3D-printable hydrogels with high mechanical strength and biocompatibility are in great demand because of their potential applications in numerous fields. In this study, a material system comprising Pluronic F-127 dimethacrylate (FDMA) is developed to function as a direct ink writing (DIW) hydrogel for 3D printing. FDMA is a triblock copolymer that transforms into micelles at elevated temperatures. The transformation increases the viscosity of FDMA and preserves its structure during DIW 3D printing, whereupon the printed structure is solidified through photopolymerization. Because of this viscosity shift, various functionalities can be incorporated through the addition of other materials in the solution state. Acrylic acid is incorporated into the pregel solution to enhance the mechanical strength, because the carboxylate group of poly(acrylic acid) ionically crosslinks with Fe3+ , increasing the toughness of the DIW hydrogel 37 times to 2.46 MJ m-3 . Tough conductive hydrogels are also 3D printed by homogenizing poly(3,4-ethylenedioxythiophene) polystyrene sulfonate into the pregel solution. Furthermore, the FDMA platform developed herein uses DIW, which facilitates multicartridges 3D printing, and because all the materials included are biocompatible, the platform may be used to fabricate complex structures for biological applications.

Abstract
Emerging evidence indicates that severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) is transmitted through the human nasal mucosa via the principal entry factors angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2), which are highly expressed in the nasal epithelium. Therefore, the biologics targeting host entry factors on human nasal mucosa will be necessary for complete control of SARS-CoV-2. Our data reveal that ACE2 was more abundant in human nasal mucosa than lung tissue. Both ACE2 and TMPRSS2 transcriptions significantly decreased in nasal epithelium in response to S. epidermidis and were relatively lower in human nasal mucus with large numbers of S. epidermidis. ACE2 transcription was also reduced in nasal epithelium in response to nasal symbiont S. aureus. This study proposes that Staphylococcus species nasal commensals might potentially restrict SARS-CoV-2 entry to the nasal epithelium via down regulation of cellular receptors coupled with reduction of principal host protease.

Abstract
This study examined the prevalence and risk factors of prediabetes and type 2 diabetes among residents of agricultural settlement villages (bateyes) in the Dominican Republic. From March to April 2016, a cross-sectional, multi-stage cluster survey was conducted across the country's three agricultural regions (southwest, east, and north). At selected households, an adult completed a questionnaire to assess demographics, diabetes knowledge, and care, and two household residents of any age provided finger-prick blood samples that were analyzed for hemoglobin A1c (HbA1c). HbA1c was categorized as normal (< 5.7%), prediabetic (5.7-6.4%), or diabetic (≥ 6.5%). The prevalence rates of diabetes and prediabetes were 8.6% (95% confidence interval [CI], 6.2-11.8%) and 20.4% (95% CI, 17.9-23.2%), respectively, among all participants (N = 1293; median age, 35 years; range, 2-96 years), and 10.0% (95% CI, 7.2-13.8%) and 20.0% (95% CI, 17.4-23.0%), respectively, among adults 18 years or older (N = 730). The average age of participants with diabetes was 47.2 years. The average age of participants with prediabetes was 40.7 years. Among adult questionnaire respondents, 64.8% of all participants and 39.4% of patients with diabetes had not been tested for diabetes previously. Among patients with diabetes, 28.4% were previously diagnosed; 1.2% of prediabetes patients were previously diagnosed. Half (50.7%) of the respondents had heard of diabetes. The majority (94.1%) of patients previously diagnosed with diabetes reported using diabetes medication. Among both undiagnosed and previously diagnosed patients with diabetes, diabetes knowledge, previous diabetes testing, and diabetes care-seeking were lowest among Haitian-born participants. A high burden of undiagnosed diabetes and deficiencies in diabetes knowledge, access to care, and diagnosis exist among all batey inhabitants, but most acutely among Haitians. Improvements will require a multi-sectoral approach.

Abstract
Pesticides and veterinary drugs are generally employed to control pests and insects in crop and livestock farming. However, remaining residues are considered potentially hazardous to human health and the environment. Therefore, regular monitoring is required for assessing and legislation of pesticides and veterinary drugs. Various approaches to determining residues in various agricultural and animal food products have been reported. Most analytical methods involve sample extraction, purification (cleanup), and detection. Traditional sample preparation is time-consuming labor-intensive, expensive, and requires a large amount of toxic organic solvent, along with high probability for the decomposition of a compound before the analysis. Thus, modern sample preparation techniques, such as the quick, easy, cheap, effective, rugged, and safe method, have been widely accepted in the scientific community for its versatile application; however, it still requires a laboratory setup for the extraction and purification processes, which also involves the utilization of a toxic solvent. Therefore, it is crucial to elucidate recent technologies that are simple, portable, green, quick, and cost-effective for onsite and infield residue detections. Several technologies, such as surface-enhanced Raman spectroscopy, quantum dots, biosensing, and miniaturized gas chromatography, are now available. Further, several onsite techniques, such as ion mobility-mass spectrometry, are now being upgraded; some of them, although unable to analyze field sample directly, can analyze a large number of compounds within very short time (such as time-of-flight and Orbitrap mass spectrometry). Thus, to stay updated with scientific advances and analyze organic contaminants effectively and safely, it is necessary to study all of the state-of-art technology.

Abstract
OBJECTIVE Our study estimates the prevalence and predictors of wearable device adoption and data sharing with healthcare providers in a nationally representative sample. MATERIALS AND METHODS Data were obtained from the 2019 Health Information National Trend Survey. We conducted multivariable logistic regression to examine predictors of device adoption and data sharing. RESULTS The sample contained 4159 individuals, 29.9% of whom had adopted a wearable device in 2019. Among adopters, 46.3% had shared data with their provider. Individuals with diabetes (odds ratio [OR], 2.39; 95% CI, 1.66-3.45; P < .0001), hypertension (OR, 2.80; 95% CI, 2.12-3.70; P < .0001), and multiple chronic conditions (OR, 1.55; 95% CI, 1.03-2.32; P < .0001) had significantly higher odds of wearable device adoption. Individuals with a usual source of care (OR, 2.44; 95% CI, 1.95-3.04; P < .0001), diabetes (OR, 1.66; 95% CI, 1.32-2.08; P < .0001), and hypertension (OR, 1.78; 95% CI, 1.44-2.20; P < .0001) had significantly higher odds of sharing data with providers. DISCUSSION A third of individuals adopted a wearable medical device and nearly 50% of individuals who owned a device shared data with a provider in 2019. Patients with certain conditions, such as diabetes and hypertension, were more likely to adopt devices and share data with providers. Social determinants of health, such as income and usual source of care, negatively affected wearable device adoption and data sharing, similarly to other consumer health technologies. CONCLUSIONS Wearable device adoption and data sharing with providers may be more common than prior studies have reported; however, digital disparities were noted. Studies are needed that test implementation strategies to expand wearable device use and data sharing into care delivery.

Abstract
BACKGROUND Despite improved survival rates, cancer survivors are experiencing worse health outcomes with complications of treatment, such as type 2 diabetes mellitus (T2D), that may deteriorate survivorship. The purpose of this review was to provide a comprehensive review of T2D incidence following cancer diagnosis. METHODS The study included: (1) cohort studies, (2) cancer diagnosis by a doctor, (3) incidence of T2D after diagnosis of cancer, and (4) adult patients over 18 years. Studies that focused on patients who had T2D as a preexisting condition at cancer diagnosis were excluded. RESULTS Of a total of 16 studies, overall incidence of T2D ranged from 5.4% to 55.3%. The highest T2D incidence rate was observed in colorectal patients with cancer (53%). While results in prostate patients with cancer were mixed, patients who underwent androgen deprivation therapy (ADT) had a significantly higher incidence of new-onset T2D (12.8%, p = 0.01). Patients treated with chemotherapy within 1-5 years of initial diagnosis of colorectal cancer were at approximately 30% higher risk of T2D. One study found that 48% of T2D was preventable with optimal management during the process of patient care. CONCLUSION Blood glucose management may allow physicians to intervene early and improve outcomes among patients with cancer.

Abstract
Optical metasurfaces are starting to find their way into integrated devices, where they can enhance and control the emission, modulation, dynamic shaping, and detection of light waves. In this study, we show that the architecture of organic light-emitting diode (OLED) displays can be completely reenvisioned through the introduction of nanopatterned metasurface mirrors. In the resulting meta-OLED displays, different metasurface patterns define red, green, and blue pixels and ensure optimized extraction of these colors from organic, white light emitters. This new architecture facilitates the creation of devices at the ultrahigh pixel densities (>10,000 pixels per inch) required in emerging display applications (for instance, augmented reality) that use scalable nanoimprint lithography. The fabricated pixels also offer twice the luminescence efficiency and superior color purity relative to standard color-filtered white OLEDs.

Abstract
Background Climacterium is a series of physical and mental symptoms occurring in women and men due to decreased levels of sex hormones. Women lose the ability to become pregnant due to decreased ovarian estrogen production; the initial symptom being hot flushes. In addition, urogenital atrophy, sexual dysfunction, mood changes, and osteoporosis occur. Extracts of Stauntonia hexaphylla (SH) and Vaccinium bracteatum (VB) fruits, with a wide range of biological activities, are widely used in traditional herbal medicine. Objective The purpose of this study was to investigate the mitigation of menopausal symptoms, such as hot flushes and postmenopausal osteoporosis after combinatorial treatment with SH and VB (SHVB) of ovariectomized (OVX) rats. Design We measured the bone regenerative effect of SHVB on receptor activator of nuclear factor-κB (NF-κB) ligand-induced osteoclast differentiation in vitro and on ovariectomy-induced osteoporosis in vivo. We investigated the effect of SHVB in a rat model of menopausal hot flushes, in which the tail skin temperature increases following ovariectomy-induced rapid decline in estrogen levels. Results SHVB inhibited osteoclast formation and tartrate-resistant acid phosphatase activity in primary mouse bone marrow-derived cells. In an estrogen deficiency-induced rat model, measurement of serum bone turnover factors showed that treatment with SHVB lowered the increased bone turnover. Additionally, SHVB decreased OVX-induced bone loss of the total femur. SHVB inhibited osteoclast differentiation, prevented bone mass reduction, and improved trabecular bone structure and biochemical markers in OVX-induced osteoporosis. In addition, administration of SHVB significantly ameliorated the changes in skin temperature in OVX rats. Conclusion SHVB improved the symptoms of menopause. These results provide the foundation for developing SHVB as a natural substance to replace hormones in the future.

Abstract
BACKGROUND Promoting physical activity is one of the most critical components in strategies to improve both individual and population health. Previous studies on electronic wearable devices (EWDs) have shown modest improvements in physical activity, including daily steps and energy expenditures. Large population-based evidence on EWDs and physical activity is needed to better understand the patterns of EWD use and physical activity. METHODS This cross-sectional study used data from the Health Information National Trends Survey 2019. We calculated weighted frequencies and prevalence of EWD utilization. Wald Chi-square test was used to compare individual characteristics by EWD use, and multivariable logistic regression model was fitted to examine the associations between EWD use and physical activity level while adjusting for sociodemographic/health-related characteristics. RESULTS The final sample included 4219 respondents representing 212,976,500 US adults aged 18 years or older. The overall utilization of EWDs in this group was 28.2 % (95 % CI, 26.0-30.5%). Respondents who used EWDs were more likely to have 150 min/week or over physical activities compared to those who did not use EWDs in the past 12 months (OR, 1.53, 95 % CI, 1.16-2.02). When restricting the analaysis to those with chronic conditions only, EWD use was still associated with higher level of physical activity (OR, 1.74, 95 % CI, 1.02-2.98). CONCLUSIONS About three in ten Americans reported using EWDs in the past year. EWD use seems to be associated with achieving a higher level of physical activity. Further studies are needed to examine the effect of EWD use on other clinical measures and subsequent health outcomes.

Abstract
OBJECTIVE The goal of this study was to estimate the incidence of falls (total, injurious, and assisted) in U.S. psychiatric care across 6 years (April 2013-March 2019). METHODS Data on falls among patients of adult and geriatric psychiatric units of general, acute care, and psychiatric hospital inpatient units from the National Database of Nursing Quality Indicators were used for this 6-year study. Total falls, assisted falls (i.e., falls broken or slowed by staff), and injurious falls were calculated, along with trends in total and injurious fall rates. RESULTS The sample included 1,159 units in 720 hospitals. Of the 119,246 falls reported, 25,807 (21.6%) resulted in injury. Only 7.0% of the total falls in psychiatric units were assisted by a staff member. Falling unassisted was associated with a higher likelihood of fall-related injury (adjusted odds ratio=1.69, 95% confidence interval=1.59 to 1.80). The total fall rate (8.55 per 1,000 patient-days) and injurious fall rate (1.97 per 1,000 patient-days) were highest for geriatric psychiatric units in general hospitals. Total and injurious fall rates in psychiatric units in general hospitals declined during the study (total fall rate declined by 10% for adult psychiatric units in general hospitals). There was no clear trend in total or injurious fall rates for units in psychiatric hospitals. CONCLUSIONS Falls are a persistent problem in psychiatric care settings. Few fall-prevention programs have been tested in these settings, which have unique risk factors for falls. Additional research is needed to develop fall-prevention interventions in psychiatric care.

Abstract
Middle East Respiratory Syndrome Coronavirus (MERS-CoV) causes severe respiratory in human with high mortality and it has been a challenge to determine optimum treatment for MERS-CoV-induced respiratory infection. Here, we observed the distribution of MERS-CoV receptors using human respiratory mucosa and also evaluated the contribution of interferon-lambdas (IFN-λs) in response to MERS-CoV infection using in vitro normal human nasal epithelial (NHNE) and bronchial epithelial (NHBE) cells. We found that the gene and protein expression of DPPIV, MERS-CoV receptor, were more dominantly located in nasal and bronchial epithelium although human nasal mucosa exhibited relatively lower DPPIV expression than lung parenchymal tissues. The quantitative mRNA level of the MERS-CoV envelope (upE) gene was significantly induced in MERS-CoV-infected cultured NHNE and NHBE cells until 3 days after infection. The induction of IFNs was identified in NHNE and NHBE cells after MERS-CoV infection and IFN-λs were predominantly increased in MERS-CoV-infected respiratory epithelial cells. Inoculation of IFN-λs to NHNE and NHBE cells suppressed MERS-CoV replication and in particular, IFN-λ4 showed a strong therapeutic effect in reducing MERS-CoV infection with higher induction of IFN-stimulated genes. Thus, IFN-λ has a decisive function in the respiratory epithelium that greatly limits MERS-CoV replication, and may be a key cytokine for better therapeutic outcomes against MERS-CoV infection in respiratory tract.

Abstract
OBJECTIVE To examine how the teach-back, interactive communication loop between patient and provider, is utilized and its role in diabetes care delivery. METHODS This was a cross-sectional analysis of the Medical Expenditure Panel Survey (MEPS) 2011-2016. The study sample included US adults aged 18 or older with diabetes. Survey-design adjusted analyses were used to examine patterns of teach-back utilization across patient socioeconomic/clinical characteristics, patient-provider interactions, and diabetes care education. RESULTS Analysis of 2901 US adults with diabetes showed that 25.0 % reported patient teach-back experience during their visit to care. Compared with patients without teach-back, those with teach-back experience had higher scores on interaction quality with their providers (composite score: 90.8 vs. 55.8, P < .001). Those with teach-back were also more to receive additional advice on diet and exercise from providers (67.0 % vs. 60.9 %, P = 0.03) and to report that they were confident in diabetes self-care management (75.7 % vs. 70.3 %, P =0.03). CONCLUSION Teach-back communication appears to be effective in patient-provider interaction and diabetes care education, leading to higher confidence in self-care management. PRACTICE IMPLICATIONS Despite its potential, the utilization of teach-back communication is suboptimal. More effort is needed to promote effective use of teach-back communication in routine diabetes care.

Abstract
IL-17 family cytokines are directly involved in host immune responses and the critical mediators for host defense against infection or inflammation. IL-17C is highly expressed in respiratory epithelium and is induced after acute bacterial lung infection. However, the definite function of IL-17C induced by Pseudomonas aeruginosa (PAO1 strain) is not fully understood, and our study was designed to demonstrate IL-17C-induced immune response against PAO1 infection in nasal epithelium. Passage-2 normal human nasal epithelial (NHNE) cells were infected with PAO1 and the relationship between IL-17C-related immune responses and the iron absorption of PAO1, depending on inoculation of recombinant human IL-17C (rhIL-17C), was assessed by measuring the siderophore activity of PAO1. Microarray data showed that IL-17C expression increased 34.7 times at 8 hours postinfection (hpi) in NHNE cells, and IL-17C mRNA levels increased until 48 hpi. The PAO1 colonies significantly increased from 8 hpi in NHNE cells, and siderophore activity of PAO1 was enhanced in the supernatants of PAO1-infected NHNE cells. Interestingly, PAO1 colonies were reduced in PAO1-infected NHNE cells treated with rhIL-17C, and supernatants from NHNE cells treated with rhIL-17C also exhibited decreased PAO1 colonies. We found that the siderophore activity of PAO1 was significantly reduced in the supernatants of NHNE cells treated with rhIL-17C where LCN2 expression was highly elevated. Our findings indicate that IL-17C mediates an antibacterial effect against PAO1 by inhibiting siderophore activity in nasal epithelium. We propose that IL-17C might be an efficient mediator to suppress PAO1 infection through disturbing iron absorption of PAO1 in nasal epithelium.
