Background Three main diagnostic types of osteoarthritic changes are distinguished in clinical and anthropological literature osteophytes, porosity, and eburnation. The nature of the relationship between these changes and how lesions progress over time is still unclear.Aim The aim of the present study is the analysis of the relationships between osteophytes, porosity, and eburnation based on skeletal material.Subjects and methods The analysis employed the skeletal collection from Cedynia (199 individuals) from tenth to fourteenth-century Poland. Marginal osteophytes (OP), porosity (POR), and eburnation (EB) were examined on a shoulder, elbow, wrist, hip, knee, and ankle.Results Osteophytes and porosity occurred independently of each other. Combinations of osteophytes and porosity (OP + POR) and osteophytes, porosity, and eburnation (OP + POR + EB) were rarely observed. Combinations of osteophytes and eburnation (OP + EB) or porosity and eburnation (POR + EB) were not found. There was a significant correlation between osteophytes and porosity in the scapula, proximal end of the ulna and proximal end of the femur. Osteophytes and eburnation were correlated at the distal end of the ulna. Porosity and eburnation were correlated at the distal end of the radius and distal end of the ulna. When all joints were considered together, all the types of osteoarthritic changes were correlated. However, the relationship between osteophytes and eburnation and between porosity and eburnation was only slightly significant. Osteophytes preceded porosity, but there were a few cases where more developed porosity accompanied less developed osteophytes.Conclusions The findings indicate that correlations between osteoarthritic changes are weak, albeit statistically significant and further studies of the relationship between changes are necessary.We investigated the mechanism of action of panaxynol (PAL) extract from the root of Saposhnikovia diviaricata (Turcz.) Schischk for treating acute liver injury caused by lipopolysaccharide (LPS) and D-galactosamine (D-Gal N) in mice. A mouse model of acute liver failure induced by LPS/D-Gal N was established. Mice were divided randomly into three equal groups control group, LPS/D-Gal N group and PAL group. After seven days of continuous PAL administration, all animals except controls were injected with 50 μg/kg LPS and 800 mg/kg D-Gal N; blood and liver samples were collected after 8 h. Compared to the LPS/D-Gal N group, the levels of catalase, glutathione and superoxide dismutase were increased in the liver of the PAL group. The inflammatory response index indicated that PAL attenuated LPS/D Gal N-induced liver pathological injury and decreased levels of hepatic malondialdehyde, serum alanine aminotransferase, aspartate transaminase, tumor necrosis factor-α, and interleukins 1β and 6. PAL also inhibited LPS/D-Gal N induced nuclear factor-kappa B (Nf-κB), inhibitor kappa B-α (IκB-α) activation, and up-regulated Nrf2 and heme oxygenase-1 (HO-1) expression. PAL can prevent LPS/D-Gal N induced acute liver injury by activating Nrf2/HO-1 to stimulate antioxidant defense and inhibit the IkB-α/NF-κB signaling pathway.Background Given a hepatitis C virus (HCV) elimination goal by 2030, World Health Organization (WHO) guidelines recommend scaling up HCV screening and treatment with highly-effective direct-acting antivirals (DAAs). This study investigated the cost-effectiveness of various screening and treatment strategies for chronic HCV patients in South Korea in patients aged over 40 as compared to currently screening only high-risk patients.Methods A published Markov disease progression model was used with a screening/treatment decision-tree to model different screening and treatment strategies for Korean HCV patients (aged over 40) from a national payer perspective over a lifetime time horizon. The screening strategies included 'screen-all' (upfront only 'once'; or upfront and age 65 'twice') or a 'high-risk only' screening strategy followed by treatment. Treatment strategies included either ledipasvir/sofosbuvir (LDV/SOF), SOF + ribavirin (SOF + RBV; in GT2 only), or glecaprevir/pibrentasvir (GLE/PIB). Model inputs were sourced from published literature and costing databases and validated by Korean hepatologists.Results Regardless of treatment strategy, a 'screen all twice' scenario led to the lowest rates of advanced liver disease events compared to 'screen all once' and 'high-risk only' screening scenarios. In this screening scenario, treatment with LDV/SOF for GT1/2 dominates (i.e., is more effective and less4costly) LDV/SOF in GT1 and SOF + RBV in GT2, while GLE/PIB is not cost-effective relative to LDV/SOF (₩105,124,920/QALY) at a willingness-to-pay threshold of 1xGDP per capita.Conclusion Screening all South Korean patients twice followed by LDV/SOF treatment is cost-effective as compared current high-risk screening. Adopting this strategy can help achieve WHO HCV elimination goals.Purpose In the absence of evidence-based guidelines, this study sought to understand current speech-language pathologists' (SLPs) practice when treating drooling in children with a neurodisability.Method Descriptive research using cross-sectional survey methodology. Online survey methods were used to obtain specific information on Australian SLPs' self-reported assessment and treatment practices relative to working with children with neurodisability who drool. Questions focussed on level of expertise, treatment approaches and barriers to evidence-based practice (EBP) in this area. Participants were sourced through three targeted associations/organisations. Data were analysed using descriptive and non-parametric statistics.Result Participants were Australian SLPs who had recent experience working with children with neurodisability who drool (n = 68). They favoured informal rather than formal methods for assessment. Preferred treatment techniques included behavioural intervention methods (46-53%) and modifying positioning (43.3%). Client suitability dominated reasoning regarding treatment selection (60%) with 57% of SLPs reporting EBP barriers.Conclusion Drooling was perceived to be a complex practice area for which SLPs desire additional education. Despite availability, valid and reliable assessments of drooling were not commonly used. Clinicians have limited evidence to support their practice further research is needed to establish evidence-based treatments for drooling.This study investigated the effect of carvedilol on aspirin-induced gastric damage. Male Wistar rats were divided into three groups. Control rats received the vehicle, while the aspirin group received aspirin (200 mg/kg) orally for 4 days. Rats of aspirin + carvedilol group were administered aspirin along with carvedilol (5 mg/kg; intraperitoneal) for 4 days. Animals were euthanized at the end of the treatment period, and gastric tissues were collected to perform histopathological and mechanistic studies. The results revealed that aspirin administration induced gastric ulcer as there were remarkable histopathological lesions in the form of marked necrosis, inflammation, hemorrhage, edema, and dysplastic changes. Lipid peroxidative markers such as malondialdehyde, 4-hydroxynonenal, and protein carbonyl were significantly elevated in the aspirin group. This was concurrent with a significant amelioration of antioxidants such as reduced glutathione, superoxide dismutase, and catalase. Furthermore, aspirin increased the immunoexpression of cyclooxygenase (COX) 2 and nuclear factor kappa-B (NF-κB). Aspirin induced elevation in the inflammatory cytokines such as tumor necrosis factor-α, interleukin-6, and interleukin-1β. Aspirin enhanced the immunoexpression of inducible nitric oxide synthetase (iNOS) and increased the level of nitrite/nitrate in gastric tissue. On the other hand, carvedilol treatment reversed all these pathological changes. Carvedilol succeeded to enhance antioxidants in gastric tissue, attenuated lipid peroxidative parameters, and suppressed the release of inflammatory mediators. It attenuated the immunoexpression of COX-2, NF-κB, and iNOS. Collectively, carvedilol has a gastro-protective effect that could be attributed to its antioxidative and anti-inflammatory properties, which modulate NF-κB/COX-2/iNOS pathways.Objectives Despite the availability of FDA-labeled anticoagulant reversal agents, there is considerable variability in clinical practice as to the regimen and agent used for reversal. The objective of this study was to characterize the current practices of pharmacists surrounding the reversal of anticoagulant-associated life-threatening hemorrhage. Methods A cross-sectional analysis of critical care and emergency medicine pharmacists. Current practice was compared for the type of hospital, country region, and type of ordering physician. In addition, pharmacists were asked to rank their involvement with activities involved with the reversal of anticoagulants. Respondents ranked their involvement with these activities as either never involved, rarely involved, occasionally involved, frequently involved, or always involved. Results281 respondents were included. The majority used 4-factor PCC for warfarin reversal (92.9%) and factor Xa inhibitor reversal (79.7%). However, only 58.7% used the labeled dose of 4-PCC for warfarin reversal. Of the 30.6% that utilized a fixed-dose regimen, the most common regimen was 1500 units once. A higher proportion of respondents practicing in a teaching hospital reported that they used activated prothrombin complex concentrates for reversal of factor Xa inhibitor (22 [12.2%] vs. 5 [5%]; p less then  0.05) or coagulation factor Xa (recombinant)-inactivated-zhzo (31 [17.2%] vs. 5 [5%]; p less then  0.05). In addition, the majority of respondents utilized idarucizumab for dabigatran reversal. The only involvement activity in which less then 50% of respondents said they were frequently involved or always involved was 'administration of reversal agent.' Conclusions There is considerable variability in which agents were utilized for anticoagulant-associated bleeding reversal.In response to a number of growing global health challenges, New York University and UNICEF designed a Behavioral Communication Strategies for Global Epidemics course that brings together United Nations professionals, government staff, and MPH (Master of Public Health) students to design innovative social behavior change communication (SBCC) strategies that address disease outbreaks and humanitarian challenges around the world. Applying a systems approach, participants in the course work on interdisciplinary teams to design strategies, develop skills, and engage in global learning. At the culmination of the course, all teams present strategies to UNICEF country offices for implementation. This innovative model for disease outbreak, public health education, and humanitarian response provides professionals with an opportunity to develop a wide range of competencies, including systems thinking, behavior change, and human-centered design and equips them with the necessary tools to develop more novel approaches to SBCC. As the number of outbreaks and humanitarian challenges increase each year, this format for learning can serve as a model for how professionals can effectively address these complex crises.
