RESUMEN
Background: Financial incentives are being increasingly adopted to help improve standards of care within general practice. However their effects on care quality are unclear. This study aimed to evaluate the impact of practices opting out of the Quality and Outcomes Framework (QOF), a financial incentive scheme in UK general practice. Study design: A retrospective before and after study of all practices in Tower Hamlets, east London. Methods: Practices were given an option by local commissioners of opting out of QOF without a financial penalty and instead opting for a locally designed financial incentive scheme that promoted more holistic care. We compared those practices which opted out of QOF to those which continued. We used national, publicly available QOF achievement data from 2016/17 and 2017/18. We undertook a sub-analysis of 16 QOF indicators to better understand the impact of the intervention. Results: Of the 36 practices in Tower Hamlets, 7 decided to continue with QOF and 29 opted out. The intervention resulted in a small but statistically significant reduction in the total QOF achievement scores of practices which opted out of QOF. The sub-analysis of 16 QOF indicators showed statistically significant reductions in most of achievement scores net of exceptions for the practices that opted out. The differences in performance between the two cohorts of practices became smaller when exceptions were included. Conclusions: The removal of QOF financial incentives can result in a reduction in achievement of QOF-related indicators but the size of the effect seems to depend on the QOF exception rates. An alternative incentive scheme that promotes a more holistic approach to care seems to be welcomed by general practices.
RESUMEN
It is unclear if cardiopulmonary resuscitation is an aerosol-generating procedure and whether this poses a risk of airborne disease transmission to healthcare workers and bystanders. Use of airborne transmission precautions during cardiopulmonary resuscitation may confer rescuer protection but risks patient harm due to delays in commencing treatment. To quantify the risk of respiratory aerosol generation during cardiopulmonary resuscitation in humans, we conducted an aerosol monitoring study during out-of-hospital cardiac arrests. Exhaled aerosol was recorded using an optical particle sizer spectrometer connected to the breathing system. Aerosol produced during resuscitation was compared with that produced by control participants under general anaesthesia ventilated with an equivalent respiratory pattern to cardiopulmonary resuscitation. A porcine cardiac arrest model was used to determine the independent contributions of ventilatory breaths, chest compressions and external cardiac defibrillation to aerosol generation. Time-series analysis of participants with cardiac arrest (n = 18) demonstrated a repeating waveform of respiratory aerosol that mapped to specific components of resuscitation. Very high peak aerosol concentrations were generated during ventilation of participants with cardiac arrest with median (IQR [range]) 17,926 (5546-59,209 [1523-242,648]) particles.l-1 , which were 24-fold greater than in control participants under general anaesthesia (744 (309-2106 [23-9099]) particles.l-1 , p < 0.001, n = 16). A substantial rise in aerosol also occurred with cardiac defibrillation and chest compressions. In a complimentary porcine model of cardiac arrest, aerosol recordings showed a strikingly similar profile to the human data. Time-averaged aerosol concentrations during ventilation were approximately 270-fold higher than before cardiac arrest (19,410 (2307-41,017 [104-136,025]) vs. 72 (41-136 [23-268]) particles.l-1 , p = 0.008). The porcine model also confirmed that both defibrillation and chest compressions generate high concentrations of aerosol independent of, but synergistic with, ventilation. In conclusion, multiple components of cardiopulmonary resuscitation generate high concentrations of respiratory aerosol. We recommend that airborne transmission precautions are warranted in the setting of high-risk pathogens, until the airway is secured with an airway device and breathing system with a filter.

OBJECTIVE: To synthesise exercise therapy intervention data investigating patient rating outcomes for the management of tendinopathy. DESIGN: A systematic review and meta-analysis of randomized controlled trials investigating exercise therapy interventions and reporting patient rating outcomes. SETTING: Any setting in any country listed as very high on the human development index. PARTICIPANTS: People with a diagnosis of any tendinopathy of any severity or duration. INTERVENTIONS: Exercise therapy for the management of tendinopathy comprising five different therapy classes: 1) resistance; 2) plyometric; 3) vibration; 4) flexibility, and 5) movement pattern retraining modalities, were considered for inclusion. MAIN OUTCOME MEASURES: Outcomes measuring patient rating of condition, including patient satisfaction and Global Rating of Change (GROC). RESULTS: From a total of 124 exercise therapy studies, 34 (Achilles: 41%, rotator cuff: 32%, patellar: 15%, elbow: 9% and gluteal: 3%) provided sufficient information to be meta-analysed. The data were obtained across 48 treatment arms and 1246 participants. The pooled estimate for proportion of satisfaction was 0.63 [95%CrI: 0.53-0.73], and the pooled estimate for percentage of maximum GROC was 53 [95%CrI: 38-69%]. The proportion of patients reporting positive satisfaction and perception of change increased with longer follow-up periods from treatment onset. CONCLUSION: Patient satisfaction and GROC appear similar and are ranked moderately high demonstrating that patients generally perceive exercise therapies positively. Further research including greater consistency in measurement tools is required to explore and where possible, identify patient- and exercise-related moderating factors that can be used to improve person-centred care.

INTRODUCTION: Radiographers can accurately report musculoskeletal and chest radiographs, but there is paucity of research comparing the performance of reporting radiographers (RRs) with consultant radiologists when interpreting and reporting abdominal radiographs. This study assessed interobserver agreement in the clinical setting between reporting radiographers and a consultant radiologist compared to an expert gastrointestinal radiologist in a District General Hospital. Major discordant reports affecting patient management were also examined. METHODS: 126 abdominal radiographs reported by 3 RRs in clinical practice were randomly selected and reported by a consultant radiologist and index gastrointestinal radiologist. The reports of the RRs and consultant radiologist were compared against the reports made by the index radiologist for agreement by a colorectal consultant surgeon. All 126 reports were scored as being in either complete agreement, minor disagreement or major disagreement which would have resulted in a change to patient management. RESULTS: There was no significant difference in overall agreement between the consultant radiologist (CR) and RRs when compared to the index radiologist (CR: n = 90/126, 71.4% and RRs: n = 94/126, 74.6%. p = 0.57). Major disagreements were found, but there was no significant difference between both groups (CR: n = 23/126, 18.3% and RRs: n = 17/126, 13.5%. p = 0.30). CONCLUSION: RRs can report abdominal radiographs to a comparable level of agreement as a consultant radiologist in the clinical setting. There was no significant difference in reports deemed to affect patient management. IMPLICATIONS FOR PRACTICE: This study addresses the gap in assessing the performance of RRs reporting abdominal radiographs. This small scale study indicates that radiographers could provide additional support in the reporting of abdominal radiographs. This would help to reduce radiologist workload and enhance the role of the reporting radiographer. CLASSIFICATION: Agreement between reporting radiographers and radiologists interpreting and reporting abdominal radiographs.

BACKGROUND: Many patients with suspected infection are presented to the emergency Department. Several scoring systems have been proposed to identify patients at high risk of adverse outcomes. METHODS: We compared generic early warning scores (MEWS and NEWS) to the (SIRS) criteria and quick Sequential Organ Failure Assessement (qSOFA), for early risk stratification in 1400 patients with suspected infection in the ED. The primary study end point was 30-day mortality. RESULTS: The AUROC of the NEWS score for predicting 30-day mortality was 0.740 (95% Confidence Interval 0.682- 0.798), higher than qSOFA (AUROC of 0.689, 95% CI 0.615- 0.763), MEWS (AUROC 0.643 (95% CI 0.583-0.702) and SIRS (AUROC 0.586, 95%CI 0.521 - 0.651). The sensitivity was also highest for NEWSâ 5 (sensitivity 75,8% specificity of 67,4%). CONCLUSION: Among patients presenting to the ED with suspected infection, early risk stratification with NEWS (cut-off of â5) is more sensitive for prediction of mortality than qSOFA, MEWS or SIRS, with adequate specificity.

Facial discoid dermatosis (FDD) is a recently described condition comprising discrete facial papulo-squamous lesions. We report three cases that clinically and histologically resemble FDD and demonstrate its resistance to treatment. Awareness of this new clinical entity will allow early diagnosis and the ability to make patients aware that there is unlikely to be a successful treatment. However, our study suggests that although FDD can persist for many years, it appears to remain stable.
RESUMEN
Childhood vaccination is an important public health intervention, yet many children remain under-vaccinated. The objective of this study was to examine infant vaccination education preferences in a population of low-income pregnant women by ethnicity, nativity, and language. Pregnant women 14-44 y old (n = 335) attending a participating low-income reproductive health clinic in southeast Texas from May 26-July 21, 2017, and who completed a paper survey offered in English and Spanish were included. Participants were asked to complete questions about their demographic characteristics and preferences about infant vaccination education. To examine differences in vaccine education preferences by participant demographic characteristics, chi-squared tests, or Fisher's exact tests and one-way analysis of variance (ANOVA) were conducted using Stata SE Version 15.1 with α = 0.05. Nearly half (47.5%) of participants considered pregnancy the best time to get information about infant vaccination and were most likely (40.6%) to indicate the nurse who gives vaccines during pregnancy as the health-care worker with whom they would like to discuss infant vaccination. There were no demographic differences in preferred timing of vaccine education delivery or provider who delivers vaccine education. Prenatal, nurse-delivered vaccine educational programs would be well accepted in this low-income population.

Ozone (O3) is a highly potent and reactive air pollutant. It has been linked to acute and chronic respiratory diseases in humans by inducing inflammation. Our studies have found evidence that 0.05 ppm of O3, within the threshold of air quality standards, is capable of inducing acute lung injury. This study was undertaken to examine O3-induced lung damage using [18F]F-FDG (2-deoxy-2-[18F]fluoro-D-glucose) microPET/CT in wild-type mice. [18F]F-FDG is a known PET tracer for inflammation. Sequential [18F]F-FDG microPET/CT was performed at baseline (i.e. before O3 exposure), immediately (0 h), at 24 h and at 28 h following 2 h of 0.05 ppm O3 exposure. The images were quantified to determine O3 induced spatial standard uptake ratio of [18F]F-FDG in relation to lung tissue density and compared with baseline values. Immediately after O3 exposure, we detected a 72.21 ± 0.79% increase in lung [18F]F-FDG uptake ratio when compared to baseline measures. At 24 h post-O3 exposure, the [18F]F-FDG uptake becomes highly variable (S.D. in [18F]F-FDG = 5.174 × 10-4 units) with a 42.54 ± 0.33% increase in lung [18F]F-FDG compared to baseline. At 28 h time-point, [18F]F-FDG uptake ratio was similar to baseline values. However, the pattern of [18F]F-FDG distribution varied and was interspersed with zones of minimal uptake. Our microPET/CT imaging protocol can quantify and identify atypical regional lung uptake of [18F]F-FDG to understand the lung response to O3 exposure.

The natural fecundity of suids, great ability to adapt to new habitats and desire for local hunting opportunities leading to translocation of feral pigs to regions where they are not yet established have all been instrumental in the home range expansion of feral swine. Feral swine populations in the United States continue to expand, wreaking havoc on agricultural lands, further compromising threatened and endangered species, and posing a microbiological threat to humans, domestic livestock and companion animals. This manuscript thoroughly reviews zoonotic diseases of concern including brucellosis, bovine tuberculosis, leptospirosis, enteric pathogens, both Salmonella spp. and shiga toxin-producing Escherichia coli, and hepatitis E. These pathogens are not a comprehensive list of microbes that are capable of infecting both humans and feral swine, but rather have been selected as they are known to infect US feral swine, direct transmission between wild suids and humans has previously been documented, or they have been shown to be readily transmitted during processing or consumption of feral swine pork. Humans that interact directly or indirectly with feral swine are at much higher risk for the development of a number of zoonotic pathogens. Numerous case reports document transmission events from feral swine and wild boar to humans, and the resulting diseases may be mild and self-limiting, chronic or fatal. Individuals that interact with feral swine should take preventative measures to minimize the risk of disease transmission and all meat should be thoroughly cooked. Additionally, public health campaigns to increase knowledge of the risks associated with feral swine are imperative.

Rigorous estimates of preference-based utilities are important inputs into economic evaluations of childhood obesity interventions, yet no published review currently exists examining utility by weight status in paediatric populations. A comprehensive systematic literature review and meta-analysis was therefore undertaken, pooling data on preference-based health state utilities by weight status in children using a random-effects model. Tests for heterogeneity were performed, and publication bias was assessed. Of 3,434 potentially relevant studies identified, 11 met our eligibility criteria. Estimates of Cohen's d statistic suggested a small effect of weight status on preference-based utilities. Mean utility values were estimated as 0.85 (95% uncertainty interval [UI] 0.84-0.87), 0.83 (95% UI 0.81-0.85), 0.82 (95% UI 0.79-0.84) and 0.83 (95% UI 0.80-0.86) for healthy weight, overweight, obese and overweight/obese states, respectively. Meta-analysis of studies reporting utility values for both healthy weight and overweight/obese participants found a statistically significant weighted mean difference (0.015, 95% UI 0.003-0.026). A small but statistically significant difference was also estimated between healthy weight and overweight participants (0.011, 95% UI 0.004-0.018). Study findings suggest that paediatric-specific benefits of obesity interventions may not be well reflected by available utility measures, potentially underestimating cost-effectiveness if weight loss in childhood/adolescence improves health or well-being.

BACKGROUND: Overall response rates (ORRs) for ipilimumab in advanced melanoma are only about 10%. Hence, it is important to explore biomarkers predicting ipilimumab responders. OBJECTIVE: We aimed to explore biomarkers to predict therapy outcome in melanoma patients who have undergone standard ipilimumab therapy in a real-world setting. METHODS: Databases of cutaneous melanoma patients (n = 52) who had received ipilimumab were reviewed and data collected on patient characteristics and diverse laboratory parameters. We performed univariate and multivariate statistics including logistic regression analysis and Cox proportional-hazards regression. RESULTS: Baseline leucocytes, lymphocytes, eosinophils, thrombocytes, neutrophil/lymphocyte ratio, thrombocytes/lymphocyte ratio, eosinophil/lymphocyte ratio and serum vitamin D levels were not significantly associated with ORR, progression-free survival (PFS) and melanoma-specific survival (MSS). Multivariate analysis confirmed anti-PD-1 pretreatment as significant predictor for ORR following ipilimumab therapy. Low-LDH levels and more than two ipilimumab cycles turned out to be significant independent predictors for prolonged PFS. Low-S100B levels and anti-PD-1 treatment before or after ipilimumab were significant independent predictors for improved MSS. All aforementioned parameters and faecal calprotectin did not turn out to be predictors for ipilimumab-induced autoimmune-related adverse events and autoimmune colitis, respectively. CONCLUSIONS: Low serum LDH before ipilimumab treatment is an independent predictor for improved PFS. Furthermore, low serum S100B is an independent predictor for MSS. The number of ipilimumab cycles (>2) is significantly associated with prolonged PFS. Pretreatment calprotectin does not predict the occurrence of autoimmune colitis under ipilimumab therapy.

SMA is a rare hereditary neuromuscular disease that causes weakness and muscle wasting as a result of the loss of spinal motor neurons. In its most severe form, SMA is the commonest genetic cause of death in infants, and children with less severe forms of SMA face the prospect of lifelong disability from progressive muscle wasting, loss of mobility and limb weakness. The initial discovery of the defective gene has been followed by major advances in our understanding of the genetic, cellular and molecular basis of SMA, providing the foundation for a range of approaches to treatment, including gene therapy, antisense oligonucleotide treatments and more traditional drug-based approaches to slow or halt disease progression. The approval by the US Food and Drug Administration (FDA) of Spinraza (nusinersen), the first targeted treatment for spinal muscular atrophy (SMA), is a historic moment. Disease-focused research charities, such as The SMA Trust (UK), continue to have a crucial role in promoting the development of additional treatments for SMA, both by funding translational research and by promoting links between researchers, people living with SMA and other stakeholders, including pharmaceutical companies and healthcare providers.

The human papillomavirus (HPV) vaccine has been available for over a decade but its uptake rate is still low. To explore the relationship between the HPV vaccination status of a child and their mother's beliefs, behaviors and knowledge, we surveyed 1497 women with at least one child aged 9-17 y between September 2011 and November 2015. Physician recommendation was the most important factor associated with reported child vaccination status. Mothers who reported receiving a provider recommendation for the HPV vaccine were 32 times more likely to have a child who had been vaccinated compared with mothers who did not report provider recommendation (aOR) = 32.17; 95% CI: 21.77, 47.54). Knowing someone who had received the vaccine was also strongly associated with vaccination uptake (59% vs 12%, p < .001). Additionally, prior HPV diagnosis (aOR = 1.91; 95% CI: 1.18, 3.10) and knowing someone with cervical cancer (aOR = 1.38; 95% CI: 1.01, 1.89) were associated with child vaccination status. Mothers who perceived moderate to high risk for their child contracting HPV or developing genital warts or cervical cancer were more likely to report that their daughters (but not their sons) had been vaccinated.

Information about the socioeconomic drivers of Silurus glanis anglers in the UK were collected using questionnaires from a cross section of mixed cyprinid fisheries to elucidate human dimensions in angling and non-native fisheries management. Respondents were predominantly male (95%), 30-40 years of age with <10 yr angling experience for S. glanis; most had received college rather than university education. The majority (34%) were employed with low-moderate income status (<£30k per annum), which may restrict time and expenditure spent on angling. Highest angling expenditure was on equipment and bait with most from southern England (54%) spending >£500 per annum. The proportion of time spent angling for S. glanis was significantly related to angler motivations; fish size, challenge in catch, tranquil natural surroundings, escape from daily stress and to be alone were considered important drivers of increased time spent angling. Overall, poor awareness of: the risks and adverse ecological impacts associated with introduced S. glanis, non-native fisheries legislation, problems in use of unlimited ground bait and high fish stocking rates in angling lakes were evident, possibly related to inadequate training and information provided by angling organisations to anglers, as many stated that they were insufficiently informed.

BACKGROUND: Reducing automobile dependence and improving rates of active transport may reduce the impact of obesogenic environments, thereby decreasing population prevalence of obesity and other diseases where physical inactivity is a risk factor. Increasing the relative cost of driving by an increase in fuel taxation may therefore be a promising public health intervention for obesity prevention. METHODS: A scoping review of the evidence for obesity or physical activity effect of changes in fuel price or taxation was undertaken. Potential health benefits of an increase in fuel excise taxation in Australia were quantified using Markov modelling to simulate obesity, injury and physical activity related health impacts of a fuel excise taxation intervention for the 2010 Australian population. Health adjusted life years (HALYs) gained and healthcare cost savings from diseases averted were estimated. Incremental cost-effectiveness ratios (ICERs) were reported and results were tested through sensitivity analysis. RESULTS: Limited evidence on the effect of policies such as fuel taxation on health-related behaviours currently exists. Only three studies were identified reporting associations between fuel price or taxation and obesity, whilst nine studies reported associations specifically with physical activity, walking or cycling. Estimates of the cross price elasticity of demand for public transport with respect to fuel price vary, with limited consensus within the literature on a probable range for the Australian context. Cost-effectiveness modelling of a AUD0.10 per litre increase in fuel excise taxation using a conservative estimate of cross price elasticity for public transport suggests that the intervention would be cost-effective from a limited societal perspective (237 HALYs gained, AUD2.6 M in healthcare cost savings), measured against a comparator of no additional increase in fuel excise. Under "best case" assumptions, the intervention would be more cost-effective (3181 HALYs gained, AUD34.2 M in healthcare cost savings). CONCLUSIONS: Exploratory analysis suggests that an intervention to increase fuel excise taxation may deliver obesity and physical activity related benefits. Whilst such an intervention has significant potential for cost-effectiveness, potential equity and acceptability impacts would need to be minimised. A better understanding of the effectiveness and cost-effectiveness of a range of transport interventions is required in order to achieve more physically active transport environments.

OBJECTIVE: To describe the hemodynamic changes that occur with sodium bicarbonate (NaHCO3) administration in premature neonates. STUDY DESIGN: This retrospective study included premature neonates 23 to 31+6 weeks of gestational age who underwent continuous cardiac and cerebral monitoring as participants in prospective trials at our institution, and who received NaHCO3 infused over 30 min in the first 24 h of life. Blood pressure (BP), heart rate, cardiac output (CO), SpO2 and cerebral oximetry (StO2) were captured every 2 s. A baseline was established for all continuous data and averaged over the 10 min before NaHCO3 administration. Baseline was compared with measurements over 10 min epochs until 80 min after administration. Arterial blood gases before and within 1 h of administration were also compared. Significance was set at P<0.05. RESULTS: A total of 36 subjects received NaHCO3 (1.3±0.3 mEq kg-1) in the first 24 h (14±8.5 h) of life. NaHCO3 administration increased pH (7.23 vs 7.28, P<0.01) and decreased base deficit (-8.9 vs -6.8, P<0.01) and PaCO2 (45 vs 43 mm Hg, P<0.05). There was a transient but significant (P<0.05) decrease in systemic BP coinciding with an increase in cerebral oxygenation without an increase in oxygen extraction. CO did not change. CONCLUSION: Early postnatal NaHCO3 administration does not acutely improve CO but does cause transient fluctuations in cerebral and cardiovascular hemodynamics in extremely premature infants.

Given the alarming prevalence of obesity worldwide and the need for interventions to halt the growing epidemic, more evidence on the role and impact of transport interventions for obesity prevention is required. This study conducts a scoping review of the current evidence of association between modes of transport (motor vehicle, walking, cycling and public transport) and obesity-related outcomes. Eleven reviews and thirty-three primary studies exploring associations between transport behaviours and obesity were identified. Cohort simulation Markov modelling was used to estimate the effects of body mass index (BMI) change on health outcomes and health care costs of diseases causally related to obesity in the Melbourne, Australia population. Results suggest that evidence for an obesity effect of transport behaviours is inconclusive (29% of published studies reported expected associations, 33% mixed associations), and any potential BMI effect is likely to be relatively small. Hypothetical scenario analyses suggest that active transport interventions may contribute small but significant obesity-related health benefits across populations (approximately 65 health adjusted life years gained per year). Therefore active transport interventions that are low cost and targeted to those most amenable to modal switch are the most likely to be effective and cost-effective from an obesity prevention perspective. The uncertain but potentially significant opportunity for health benefits warrants the collection of more and better quality evidence to fully understand the potential relationships between transport behaviours and obesity. Such evidence would contribute to the obesity prevention dialogue and inform policy across the transportation, health and environmental sectors.

Immunization coverage of vulnerable children is often sub-optimal in many low- and middle-income countries. The use of a reminder/recall (R/R) system has been one of the strategies shown to be effective in improving immunization rates. In the resent study, we evaluated the effect of R/R and Primary Health Care Immunization Providers' Training (PHCIPT) intervention on routine immunization completion among 595 infants in Ibadan, Nigeria. The design was a group randomized controlled trial with Local Government Area (LGA) being the unit of randomization. Four randomly selected LGAs were randomized to receive a cellphone R/R only (A), a PHCIPT only (B); combined R/R and PHCIPT (C) intervention or serve as a control group (D). Children aged 0-12 weeks were consecutively recruited into each group and followed up for 12 months. The primary outcome measure was routine immunization completion at 12 months of age. At the study endpoint, immunization completion rates were: group A, 98.6 %; group B, 70 %; group C, 97.3 %; and group D, 57.3 %. Compared to the control group, the cellphone R/R group was 72 % (RR 1.72, 95 % CI 1.50-1.98) and the combined RR/PHCIPT group 70 % (RR 1.70, 95 % CI 1.47-1.95) more likely to complete immunization. In contrast, immunization completion in the PHCIPT group was marginally different from the control group (RR 1.22, 95 % CI 1.03-1.45). These findings remained robust to adjustment for potential predictors of immunization completion as covariates. In conclusion, cellphone reminder/recall was effective in improving immunization completion in this Nigerian setting. Its use is recommended for large scale implementation.

OBJECTIVE: To investigate the potential effects of IFN-03A5 on the responsiveness of human gingival fibroblasts to bacterial challenge. DESIGN: mRNA and protein expression of CD14, TLR2 and TLR4 in human gingival fibroblasts was detected by quantitative polymerase chain reaction (Q-PCR) and flow cytometry. The effect of preincubation with IFN-03A5 on subsequent bacterial LPS-induced expression of IL-6 and IL-8 by gingival fibroblasts was determined by ELISA. Bacterial LPS-induced IκBα degradation in human gingival fibroblasts was investigated by western blot. RESULTS: Human gingival fibroblasts express CD14, TLR2 and TLR4 mRNAs. IFN-03A5, but not IL-103B2, induced mRNA expression of all three receptors and the expression of membrane bound CD14 protein. Pre-incubation of fibroblasts with IFN-03A5 and subsequent stimulation with Escherichia coli LPS or Porphyromonas gingivalis LPS led to increased production of IL-6 and IL-8. LPS-induced pro-inflammatory cytokine production was abrogated by a blocking antibody to CD14. Both E. coli LPS and P. gingivalis LPS induced IκBα degradation in human gingival fibroblasts. CONCLUSION: Our data indicate that IFN-03A5 primes human gingival fibroblasts, through the upregulation of CD14 expression, which results in increased responsiveness to bacterial LPS challenge, as determined by pro-inflammatory cytokine production.
