Clinical Assessment of Preemptive Analgesia on Success of Pulpal Anesthesia and Postendodontic Pain in Children with Irreversible Pulpitis: A Randomized Comparative Study.

Introduction: Optimal pain management of symptomatic pulpitis in formative years goes a long way in developing a positive dental attitude. Efforts should be made to increase the success of anesthesia, thus diminishing negative dental experiences. The aim of the study was to assess the efficacy of preemptive analgesia on the success of pulpal anesthesia following inferior alveolar nerve block (IANB) in children with symptomatic irreversible pulpitis and on reducing postendodontic pain. Materials and methods: The research design was an in vivo, three-group, parallel, quadruple-blind study. A total of 75 patients were randomly allocated to one of the three groups-group I: ibuprofen, group II: combination of ibuprofen and paracetamol, and group III: multivitamin (placebo). Premedication was given 45 minutes before treatment, and patients received IANB in a standardized manner. Pain during pulpectomy was recorded using the face, legs, activity, cry, consolability (FLACC) scale and postoperatively using Wong-Baker's pain rating scale (WBPRS) at 4, 12, and 24 hours. Success was measured if the pain felt was of no or mild intensity. Results: Success of IANB was 64% for ibuprofen, 72% for the combination group, and 40% for the placebo group, with no statistically significant difference between all groups (p = 0.06) on the FLACC scale. At 4 hours postoperatively, a significant difference (p = 0.02) was found among groups with more children experiencing no or mild pain in groups I and II and the highest number of rescue medications taken by the placebo group. Conclusion: Ibuprofen and a combination of ibuprofen and acetaminophen as preemptive analgesics had no significant effect on the success rate of IANB, although it was effective in reducing pain at 4 hours postoperatively.

Neuronal pentraxin 2 correlates with neurodegeneration but not cognition in idiopathic normal pressure hydrocephalus (iNPH).

AIM OF THE STUDY: Neuronal pentraxin-2 (NPTX2) is a synaptic protein responsible for modulating plasticity at excitatory synapses. While the role of NPTX2 as a novel synaptic biomarker in cognitive disorders has been elucidated recently, its role in idiopathic normal pressure hydrocephalus (iNPH) is not yet understood. CLINICAL RATIONALE FOR STUDY: To determine if NPTX2 predicts cognition in patients with iNPH, and whether it could serve as a predictive marker for shunt outcomes. MATERIAL AND METHODS: 354 iNPH patients underwent cerebrospinal fluid drainage (CSF) as part of the tap test or extended lumbar drainage. Demographic and clinical measures including age, Evans Index (EI), Montreal Cognitive Assessment (MoCA) score, Functional Activities Questionnaire (FAQ) score, and baseline and post-shunt surgery Timed Up and Go (TUG) test scores were ascertained. CSF NPTX2 concentrations were measured using an ELISA. CSF ß-amyloid 1-40 (Aß1-40), ß-amyloid 1-42 (Aß1-42), and phosphorylated tau-181 (pTau-181) were measured by chemiluminescent assays. Spearman's correlation was used to determine the correlation between CSF NPTX2 concentrations and age, EI, MoCA and FAQ, TUG, Aß1-40/Aß1-42 ratio, and pTau-181 concentrations. Logistic regression was used to determine if CSF NPTX2 values were a predictor of short-term improvement post-CSF drainage or long-term improvement post-shunt surgery. RESULTS: There were 225 males and 129 females with a mean age of 77.7 years (± 7.06). Average CSF NPTX2 level in all iNPH patients was 559.97 pg/mL (± 432.87). CSF NPTX2 level in those selected for shunt surgery was 505.61 pg/mL (± 322.38). NPTX2 showed modest correlations with pTau-181 (r = 0.44, p < 0.001) with a trend for Aß42/Aß40 ratio (r = -0.1, p = 0.053). NPTX2 concentrations did not correlate with age (r = -0.012, p = 0.83) or MoCA score (r = 0.001, p = 0.87), but correlated negatively with FAQ (r = -0.15, p = 0.019). CONCLUSIONS: While CSF NPTX2 values correlate with neurodegeneration, they do not correlate with cognitive or functional measures in iNPH. CSF NPTX2 cannot serve as a predictor of either short-term or long-term improvement after CSF drainage. CLINICAL IMPLICATIONS: These results suggest that synaptic degeneration is not a core feature of iNPH pathophysiology.

Community-Based Diabetes Awareness Strategy With Detection and Intervention: The Mobile Diabetes Education Center.

To prevent diabetes and increase equitable access to health care screenings, Touro University California has created and implemented a community outreach program called the Mobile Diabetes Education Center (MOBEC). This program is a joint effort that also involves Sutter Health, the California Department of Public Health, Kaiser Permanente, the Solano County Department of Public Health, and community-based organizations, focusing on advancing health equity in Solano County's at-risk populations. This article reports on the services and initial successes of MOBEC. With its strong community collaboration, MOBEC has helped to raise awareness of diabetes and ensure access to much-needed health screenings and education. This model can potentially be used as a blueprint for similar efforts nationwide to address the health care needs of medically underserved communities.

Structural and functional studies reveal the molecular basis of substrate promiscuity of a glycosyltransferase originating from a major agricultural pest.

The two-spotted spider mite, Tetranychus urticae, is a major cosmopolitan pest that feeds on more than 1100 plant species. Its genome contains an unprecedentedly large number of genes involved in detoxifying and transporting xenobiotics, including 80 genes that code for UDP glycosyltransferases (UGTs). These enzymes were acquired via horizontal gene transfer from bacteria after loss in the Chelicerata lineage. UGTs are well-known for their role in phase II metabolism; however, their contribution to host adaptation and acaricide resistance in arthropods, such as T. urticae, is not yet resolved. TuUGT202A2 (Tetur22g00270) has been linked to the ability of this pest to adapt to tomato plants. Moreover, it was shown that this enzyme can glycosylate a wide range of flavonoids. To understand this relationship at the molecular level, structural, functional, and computational studies were performed. Structural studies provided specific snapshots of the enzyme in different catalytically relevant stages. The crystal structure of TuUGT202A2 in complex with UDP-glucose was obtained and site-directed mutagenesis paired with molecular dynamic simulations revealed a novel lid-like mechanism involved in the binding of the activated sugar donor. Two additional TuUGT202A2 crystal complexes, UDP-(S)-naringenin and UDP-naringin, demonstrated that this enzyme has a highly plastic and open-ended acceptor-binding site. Overall, this work reveals the molecular basis of substrate promiscuity of TuUGT202A2 and provides novel insights into the structural mechanism of UGTs catalysis.

pH stimuli-responsive hydrogels from non-cellulosic biopolymers for drug delivery.

Over the past several decades, there has been significant growth in the design and development of more efficient and advanced biomaterials based on non-cellulosic biological macromolecules. In this context, hydrogels based on stimuli-responsive non-cellulosic biological macromolecules have garnered significant attention because of their intrinsic physicochemical properties, biological characteristics, and sustainability. Due to their capacity to adapt to physiological pHs with rapid and reversible changes, several researchers have investigated pH-responsive-based non-cellulosic polymers from various materials. pH-responsive hydrogels release therapeutic substances in response to pH changes, providing tailored administration, fewer side effects, and improved treatment efficacy while reducing tissue damage. Because of these qualities, they have been shown to be useful in a wide variety of applications, including the administration of chemotherapeutic drugs, biological material, and natural components. The pH-sensitive biopolymers that are utilized most frequently include chitosan, alginate, hyaluronic acid, guar gum, and dextran. In this review article, the emphasis is placed on pH stimuli-responsive materials that are based on biological macromolecules for the purposes of drug administration.

A comparative assessment of efficacy and preference between needleless device INJEX and insulin syringe for anesthetizing primary maxillary teeth in children aged 4-9 years: A split-mouth crossover randomized clinical study.

insulin syringe for anesthetizing primary maxillary teeth in children aged 4-9 years. Materials and Methods: This randomized clinical study included 46 children aged 4-9 years. The patients were digitally allotted to receive 4% articaine for extractions of primary maxillary teeth, either using needleless device INJEX or insulin syringe on each side of the maxillary arch, in two different appointments after a 1-week washout period. Pain perception was measured by the subjective (Faces Pain Scale-Revised [FPS-R]) and objective pain scores (Face, Legs, Activity, Cry, and Consolability [FLACC]) and hemodynamic parameters (heart rate and oxygen saturation) during LA administration and during extractions. After the second appointment, children were asked about their preference between needleless device INJEX and insulin syringe. Results: On evaluating subjective pain scores with FPS-R, intergroup differences between the INJEX and insulin syringe groups were found statistically insignificant, both during LA administration (P = 0.101) and extraction (P = 0.080). However, on assessing pain objectively during extraction using FLACC, the mean pain score was less with insulin syringe (2.78) as compared to INJEX (4.72) and the difference was statistically significant (P = 0.000). There was no significant difference in patient preference between the two methods. Conclusion: Pain perception was minimal during local anesthesia administration using needleless device INJEX; however, its clinical efficacy during extractions was reported to be lower than insulin syringe. Background: Managing pain in children is the most challenging task as it forms the foundation for instilling positive behavior toward dental treatment. Adequate local anesthesia (LA) is the cornerstone of pain management. However, the fear of needles, particularly in young children, can result in complete avoidance and refusal of treatment. Aim: This study aimed to evaluate and compare the efficacy and preference between needleless device INJEX and.

Exploratory Assessment of Proteomic Network Changes in Cerebrospinal Fluid of Mild Cognitive Impairment Patients: A Pilot Study.

(1) Background: Despite the existence of well-established, CSF-based biomarkers such as amyloid-ß and phosphorylated-tau, the pathways involved in the pathophysiology of Alzheimer's disease (AD) remain an active area of research. (2) Methods: We measured 3072 proteins in CSF samples of AD-biomarker positive mild cognitive impairment (MCI) participants (n = 38) and controls (n = 48), using the Explore panel of the Olink proximity extension assay (PEA). We performed group comparisons, association studies with diagnosis, age, and APOE ε4 status, overrepresentation analysis (ORA), and gene set enrichment analysis (GSEA) to determine differentially expressed proteins and dysregulated pathways. (3) Results: GSEA results demonstrated an enrichment of granulocyte-related and chemotactic pathways (core enrichment proteins: ITGB2, ITGAM, ICAM1, SELL, SELP, C5, IL1A). Moreover, some of the well-replicated, differentially expressed proteins in CSF included: ITGAM, ITGB2, C1QA, TREM2, GFAP, NEFL, MMP-10, and a novel tau-related marker, SCRN1. (4) Conclusion: Our results highlight the upregulation of neuroinflammatory pathways, especially chemotactic and granulocyte recruitment in CSF of early AD patients.

Novel fully automated prototype assays for specific detection of phosphorylated and non-phosphorylated Hepatitis B core antigens.

BACKGROUND: Hepatitis B core antigen (HBcAg) has been proposed as a surrogate marker to reflect transcriptional activity of HBV covalently closed circular DNA (cccDNA) during active infections and may be a valuable tool to monitor the efficacy of antiviral therapies. However, HBcAg-specific immunoassays are unavailable, and current assays that measure hepatitis B core-related antigen (HBcrAg) cannot distinguish between HBcAg, HBeAg, and precore (PreC) proteins. OBJECTIVE: Two fully automated assays were developed to specifically detect phosphorylated HBcAg (P-HBcAg, representing non-HBV DNA-containing particles) and non-phosphorylated HBcAg (representing HBV DNA-containing particles) circulating in HBV infected patients. STUDY DESIGN: P-HBcAg and HBcAg levels were analyzed in 124 single timepoint patients with active infections, in three longitudinal specimens from patients with acute HBV infections, and in four chronic hepatitis B (CHB) patients on-therapy (TDF - tenofovir disoproxil fumarate, pegIFN - pegylated interferon, NAPs - nucleic acids polymers). RESULTS: Analyzing acute infections revealed that P-HBcAg and HBcAg levels correlate more closely than HBcrAg to HBV DNA. During antiviral treatment of CHB patients, HBcAg correlates well with HBV DNA and indicates a therapeutic response to the treatment at the beginning of the therapy. In contrast, P-HBcAg tracks more closely to HBV RNA. Importantly, P-HBcAg is detectable several months after HBcAg became undetectable indicating that cccDNA is still transcriptionally active in hepatocytes. CONCLUSIONS: Overall, the ability to specifically distinguish between the various states of HBcAg (phosphorylated and non-phosphorylated) can provide additional insights for disease staging, drug development, and management of HBV therapies.

Impact of Pharmacist Integration Into Primary Care on Reimbursement for Hospital Follow-Up Visits.

BACKGROUND: The financial and clinical impact of transitional care management (TCM) outcomes through pharmacist integration within primary care is not well described. OBJECTIVES: The primary objective of this study was to determine the financial impact of pharmacist conducted post-discharge phone calls. The secondary objectives included readmission rates and number of interventions. METHODS: A computer-generated list identified patients discharged from St. Joseph's/Candler Health System (SJ/C) with a listed primary care provider within the SJ/C Primary Care Medical Group at Eisenhower from November 1, 2019 to April 30, 2020. Eligible patients who received a post-discharge phone call from a pharmacist were compared to those who received a call by another staff member. Data was collected regarding the financial impact of pharmacist conducted post-discharge phone calls. Readmission rates and medication related interventions were also assessed. RESULTS: There were 104 patients discharged meeting criteria. Twenty-four patients were contacted by a pharmacist resulting in 20 subsequent hospital follow up appointments scheduled with the provider. Total amount billed for those appointments was $4220 (average of $211 per visit). Twenty-five calls were made by non-pharmacist staff with 23 appointments scheduled. Total amount billed for those appointments was $2445 (average of $106 per visit). Increased reimbursement was generated by a qualifying 2-way communication by the pharmacist as outlined by Center for Medicaid and Medicare Services enabling providers to bill for a TCM visit versus standard office visit. Pharmacists made 33 clinical interventions including medication reconciliation, medication procurement, referrals, lab orders, and education. One intervention was made by non-pharmacist staff. The 30-day readmission rate for pharmacist contacted patients was 8% versus 12% for non-pharmacist contacted patients. CONCLUSIONS: Pharmacist involvement in TCM while integrated into a primary care office is previously not well described. This data highlights an opportunity for pharmacists to demonstrate sustainability and improved outcomes related to TCM.

A comparative evaluation of light cure calcium silicate and resin-modified glass ionomer as indirect pulp capping agent in primary molars: A randomized clinical trial.

Background: Minimally invasive techniques should be employed to maintain pulp vitality without affecting physiological tooth resorption for pediatric patients. This study aims to evaluate clinical and radiographic success of light cure calcium silicate and resin-modified glass ionomer (RMGI) as indirect pulp-capping agent in primary molars in children between 5 and 9 years. Materials and Methods: In this randomized clinical trial study, 40 primary molars with the International Caries Detection and Assessment System criteria 4-6 score were divided randomly into two groups after computerized randomization method. After caries excavation by minimally invasive dentistry principle, affected dentin was lined by either light cure calcium silicate (Group I) or RMGI (Group II) liner followed by composite restoration. Clinical success was determined with the absence of symptoms and bitewing radiographs were taken at baseline, 3, and 6 months' interval to measure increase in dentin increment using ImageJ software. Statistical analysis for intergroup comparison was done using Paired t-test, and Independent t-test was used for intragroup comparison. The level of statistical significance was set at P < 0.05. Results: Change in dentin increment seen from baseline to 6 months in Group I was 0.19 mm and in Group II was 0.20 mm (P = 0.924). Intragroup increment was statistically significant during all follow-up intervals for both the groups (Group I - P ≤ 0.001, Group II - P = 0.009). For baseline remaining dentin thickness >1.5 mm, statistically significant increase was observed in the dentin increment at 3 months' interval between both the groups. Conclusion: Both TheraCal LC and Vitrebond show acceptable clinical and radiographic results when used in primary molars as indirect pulp treatment agents. Both the liners are equivalent to each other in terms of feasibility and cost-effectiveness but TheraCal LC can be preferred due to better handling and avoiding the manipulation step thereby reducing treatment time.

Lymphocyte antigen 6K signaling to aurora kinase promotes advancement of the cell cycle and the growth of cancer cells, which is inhibited by LY6K-NSC243928 interaction.

Lymphocyte antigen 6K (LY6K) is a small GPI-linked protein that is normally expressed in testes. Increased expression of LY6K is significantly associated with poor survival outcomes in many solid cancers, including cancers of the breast, ovary, gastrointestinal tract, head and neck, brain, bladder, and lung. LY6K is required for ERK-AKT and TGF-ß pathways in cancer cells and is required for in vivo tumor growth. In this report, we describe a novel role for LY6K in mitosis and cytokinesis through aurora B kinase and its substrate histone H3 signaling axis. Further, we describe the structural basis of the molecular interaction of small molecule NSC243928 with LY6K protein and the disruption of LY6K-aurora B signaling in cell cycle progression due to LY6K-NSC243928 interaction. Overall, disruption of LY6K function via NSC243928 led to failed cytokinesis, multinucleated cells, DNA damage, senescence, and apoptosis of cancer cells. LY6K is not required for vital organ function, thus inhibition of LY6K signaling is an ideal therapeutic approach for hard-to-treat cancers that lack targeted therapy such as triple-negative breast cancer.

Development of fluorophore labeled or biotinylated anticancer small molecule NSC243928.

Small molecule NSC243928 binds with LY6K, a potential target for the treatment of triple-negative breast cancer, and induces cancer cell death with an unclear mechanism. We have developed chemical tools to identify the molecular mechanisms of NSC243928-LY6K interaction. Herein, we report on the development and synthesis of biotinylated and fluorophore-tethered derivatives of NSC243928 guided by docking studies and molecular dynamics. Surface plasmon resonance assay indicates that these derivatives retained a direct binding with LY6K protein. Confocal analysis revealed that nitrobenzoxadiazole (NBD) fluorophore tagged NSC243928 is retained in LY6K expressing cancer cells. These novel modified compounds will be employed in future in vitro and in vivo studies to understand the molecular mechanisms of NSC243928 mediated cancer cell death. These studies will pave the path for developing novel targeted therapeutics and understanding any potential side-effects of these treatments for hard-to-treat cancers such as triple-negative breast cancer or other cancers with high expression of LY6K.

Clinical and Radiographic Evaluation of Different Glass Ionomer Restorative Materials in Primary Molars: A Comparative Randomized Clinical Trial.

Aim: The study aimed to evaluate and compare the clinical and radiographic success rate of Ketac Universal (3M), GC 9 EXTRA (GC), and Cention N (Ivoclar) restorative materials in primary molars. Materials and methods: The study was conducted as randomized clinical trial in children aged 3-8 years old, out of which a total of 75 primary molars were selected in 43 patients who met the inclusion criteria. The sample size was further divided into three groups of restorative materials, which included group I-Ketac Universal (n = 25), group II-GC 9 EXTRA (n = 25), and group III-Cention N (n = 25). Class I restorations were placed randomly according to the computerized randomization in primary molars and evaluated at baseline (1 week), 6 months, and 12 months according to modified United States Public Health Service (USPHS) criteria and bitewing radiographs. Results: On intercomparison of three groups at 12 months, there was no significant difference found, while on pairwise comparison of Ketac Universal and Cention N, there was a significant difference in relation to surface texture (p = 0.04*) and anatomic contour (p = 0.04*) at 12 months. Conclusion: Newly introduced restorative material Cention N exhibited improved physical and mechanical properties and can be recommended as a cost-effective restorative and easy-to-use material in posterior load-bearing primary molars. Clinical significance: Restoration of primary teeth continues to be an important aspect of restorative dentistry. The longevity of restorations in primary teeth is significantly different for all materials compared to permanent dentition. This makes the assessment of these restorations as a separate group meaningful. How to cite this article: Kataria VG, Patel MC, Bhatt R, et al.

Severity of Illness Impacts Outcomes More than Admitting Service for Isolated Hip Fracture Patients.

INTRODUCTION: Isolated hip fractures (IHF) are common injuries in the elderly. Controversy exists about which hospital service is best suited to manage these patients. We hypothesize that baseline patient severity of illness (SOI) score drives patient outcomes, not the hospital service managing these patients. METHODS: Retrospective review of all IHF patients from 2014 to 2018 at our Level 1 trauma center. Basic demographics were obtained. Patients were divided into service line they were admitted; surgical vs non-surgical. Primary outcomes included hospital length of stay (HLOS), time to OR, time to VTE prophylaxis, complication rate (defined by the Trauma Quality Improvement Program), 30-day mortality, and readmissions. SOI score (which is DRG-based) was controlled to see if any differences in primary outcomes occurred between cohorts. Chi-square was used for categorical variables and regression analysis for continuous variables. Significance was p < 0.05. RESULTS: A total of 366 total patients were analyzed with the same ISS. A total of 102 were admitted to a surgical service and 264 to a non-surgical service. Average overall age was 80 year, 66.9% were female, and 86% were Caucasian. There was no statistical difference between outcomes when comparing admitting services. Controlling for SOI score, there was no difference between admitting service for outcomes as well. SOI score was a significant predictor for increased HLOS and complication occurrence (p < 0.001) via regression analysis, with a 6.06-fold increase in complication rate from mild to moderate SOI score (p = 0.001). CONCLUSION: There is no difference in outcomes based on admitting service and process measures. However, the SOI score is perhaps a better predictor of outcomes for isolated hip fracture patients.

Comparison of long-term outcomes from rib fractures for patients undergoing both operative and non-operative management: a survey analysis.

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) has been gaining popularity for the treatment of rib fractures. Limited literature exists regarding the long-term effects of SSRF versus non-operative (NO) intervention. The goal of this study is to better understand these long-term effects, hypothesizing SSRF patients have better outcomes. METHODS: IRB approved survey study at our Level I trauma center. Patients suffering rib fractures from 1/2017 through 1/2019 were surveyed via phone call and asked five questions. Basic demographics obtained. The five survey questions asked: "Are you still experiencing pain from your rib fractures?"; "If yes, how would you rate your pain 1-10?"; "Are you back to your baseline activity level?"; "If no, is this related to your rib fractures?"; "Do you feel your rib fractures moving/clicking?" Paired t test, Chi square, and median tests were utilized. Significance was set at p < 0.05. RESULTS: 527 patients were called with 228 unsuccessfully reached. 47 refused to participate. 252 patients (47.8%) participated in the survey; 78 SSRF and 174 NO. Age and gender were similar between cohorts. Majority of patients suffered blunt trauma. No significant difference between ISS; 15 SSRF vs 14 NO. SSRF patients had worse chest trauma with median chest AIS of 3 (IQR 3-4) vs 3 (IQR 3-3) for NO (p < 0.001). Response to survey questions revealed similar incidences of pain between SSRF and NO cohorts (28.2% vs 27.6%; p = 0.939), however decreased pain scores for SSRF group (2 vs 4; p = 0.006). Return to baseline activity was better for the SSRF group (75.6% vs 56.3%; p = 0.143) and the incidence of rib fractures being the reason for patients not returning to baseline was decreased (26.3% vs 44.7%; p = 0.380). Lastly, SSRF resulted in significantly less movement of rib fractures (3.8% vs 13.8%; p = 0.031). CONCLUSION: Patients who undergo SSRF show significant long-term improvements in pain scores and better return to baseline function with less overall issues from their rib fractures compared to those managed non-operatively.

Safety, antiviral activity and pharmacokinetics of JNJ-64530440, a novel capsid assembly modulator, as 4 week monotherapy in treatment-naive patients with chronic hepatitis B virus infection.

OBJECTIVES: We investigated JNJ-64530440 (a hepatitis B virus capsid assembly modulator) safety, antiviral activity and pharmacokinetics in patients with chronic hepatitis B (CHB) (Phase 1b, NCT03439488). METHODS: Twenty treatment-naive, HBeAg-positive or -negative CHB patients were randomized 4|:|1 to JNJ-64530440 750 mg once or twice daily, or placebo for 28 days. RESULTS: All patients (mean age 43.8 years; 85% male; 70% White; 20% HBeAg positive) completed dosing/28 day follow-up. Mild-to-moderate treatment-emergent adverse events occurred in 3/4 (placebo), 6/8 (once-daily) and 4/8 (twice-daily) patients; mostly fatigue, increased alanine aminotransferase, decreased neutrophil count, and headache. Hepatitis B virus (HBV) DNA was substantially reduced; mean (range) changes from baseline at day 29 were: -3.2 (-2.4 to -3.9) (once-daily) and -3.3 (-2.6 to -4.1) (twice-daily) log10 IU/mL; placebo 0.1 (0.7 to -0.6) log10 IU/mL. HBV DNA levels were below the lower limit of quantification (LLOQ) in 5/8 (once-daily) and 3/8 (twice-daily) patients. For patients with detectable baseline HBV RNA, mean (SE) changes versus baseline in HBV RNA at day 29 were: -2.65 (0.81) (once-daily) and -2.94 (0.33) (twice-daily) log10 copies/mL. HBV RNA levels were 'target not detected' in 4/6 (once-daily) and 3/7 (twice-daily) patients. JNJ-64530440 pharmacokinetics in CHB patients were comparable with those in healthy volunteers. CONCLUSIONS: JNJ-64530440 750 mg once-daily or twice-daily for 28 days was well tolerated and achieved potent antiviral activity in CHB patients.

'Us-Versus-Them': Othering in COVID-19 public health behavior compliance.

OBJECTIVE: We explored public perceptions about the COVID-19 pandemic to learn how those attitudes may affect compliance with health behaviors. METHODS: Participants were Central Pennsylvania adults from diverse backgrounds purposively sampled (based on race, gender, educational attainment, and healthcare worker status) who responded to a mixed methods survey, completed between March 25-31, 2020. Four open-ended questions were analyzed, including: "What worries you most about the COVID-19 pandemic?" We applied a pragmatic, inductive coding process to conduct a qualitative, descriptive content analysis of responses. RESULTS: Of the 5,948 respondents, 538 were sampled for this qualitative analysis. Participants were 58% female, 56% with ≥ bachelor's degree, and 50% from minority racial backgrounds. Qualitative descriptive analysis revealed four themes related to respondents' health and societal concerns: lack of faith in others; fears of illness or death; frustration at perceived slow societal response; and a desire for transparency in communicating local COVID-19 information. An "us-versus-them" subtext emerged; participants attributed non-compliance with COVID-19 behaviors to other groups, setting themselves apart from those Others. CONCLUSION: Our study uncovered Othering undertones in the context of the COVID-19 pandemic, occurring between groups of like-minded individuals with behavioral differences in 'compliance' versus 'non-compliance' with public health recommendations. Addressing the 'us-versus-them' mentality may be important for boosting compliance with recommended health behaviors.

Evaluation of silver-modified atraumatic restorative technique versus conventional pulp therapy in asymptomatic deep carious lesion of primary molars - A comparative prospective clinical study.

Background: Lately, a paradigm shift from radical to conservative approach has popularized the selective caries removal over complete excavation in deep caries. Indirect pulp therapy over pulpotomy is being preferred due to risk of questionable pulp vitality in carious exposure of pulp. Silver diamine fluoride can be a useful tool for noninvasive caries management due to its antimicrobial and remineralization properties. Aim: The study aims to evaluate the success of minimum intervention approach using silver-modified atraumatic restorative technique (SMART) as indirect pulp treatment compared to conventional vital pulp therapy in symptomless deep carious lesions of primary molars. Materials and Methods: In this comparative, prospective, double-blinded, clinical interventional study, 60 asymptomatic primary molar teeth with international caries detection and assessment system score 4-6 were selected in children aged 4-8 years and were randomly allocated into SMART and conventional groups. The success of the treatment approach was assessed using clinical and radiographic criteria at baseline, 3, 6, and 12 months interval. Results: Data were analyzed using Pearson Chi-Square test at a significance level of 0.05. Conventional group showed 100% and SMART observed 96.15% clinical success at 12 months follow up (P > 0.05). One radiographic failure due to internal resorption at 6 months in SMART and one in the conventional group at 12 months was reported though the difference was insignificant (P > 0.05). Conclusion: Removal of all infected dentin in deep carious lesions is not required for successful caries treatment and SMART can be recommended as a potential biologic approach to manage asymptomatic deep dentinal lesions, based on optimal case selection.
