Osteoarthritis (OA) is a degenerative pathological condition of the appendicular joints which affects the cartilage and underlying bone. OA is relatively common in both the archaeological and clinical context, and a significant amount of research has been conducted on this osteological condition. The purpose of this thesis is to assess the incidence, demographic prevalence, and general severity of hip and knee OA in a Roman-Christian period (50 A.D (-) 450 A.D) population sample from the...
Show moreOsteoarthritis (OA) is a degenerative pathological condition of the appendicular joints which affects the cartilage and underlying bone. OA is relatively common in both the archaeological and clinical context, and a significant amount of research has been conducted on this osteological condition. The purpose of this thesis is to assess the incidence, demographic prevalence, and general severity of hip and knee OA in a Roman-Christian period (50 A.D (-) 450 A.D) population sample from the Dakhleh Oasis, Egypt. The bioarchaeological sample originates from the Kellis 2 cemetery which is associated with the ancient town of Kellis. The town of Kellis is believed to have been a prosperous economic hub in Egypt, located in the Western Sahara Desert approximately 250 kilometers west of the Nile. The skeletal samples (n=135, 83 females and 51 males) was visually assessed for the osteological characteristics of OA in the hips and the knees. Joint surfaces of the hip include the acetabulum and femoral head. Joint surfaces of the knee include lateral/medial tibio-femoral compartments and the patellofemoral compartment. The ages of the individuals assessed in this study range from 19-72 years, and have been divided into five age categories which were then cross-tabulated with sex and OA incidence in order to determine demographic prevalence of OA. Findings indicate that age is a significant etiological factor of OA prevalence for both males and females. Males are afflicted by the disease significantly more than females in the hips (F: [L] 3.6%, [R] 5.9% and M: [L] 13.7%,[R] 13.7%) and also slightly more affected in the knees(F: [L] 17.5%,[R] 18.3% and M: [L] 22.9%,[R]21.3%). The acetabulum tends to be more arthritic than the femoral head for both males and females. Femoral condyles tend to be more arthritic than tibial condyles for both males and females. The patello-femoral compartment tends to be the most arthritic part of the knee while the medial condyles of both tibiae exhibit virtually no OA (with the exception of one individual). The joint surface observed with the highest OA prevalence is the femoral surface of the patella (F: [L] 17.5%,[R] 15.9% and M: [L] 21.3%,[R] 21.3%). The highest prevalence of OA by joint complex is observed on the left knee in males (22.9%), and the lowest prevalence of OA is observed on the left hip of females (3.6%). Both hip and knee joints have higher prevalence of unilateral OA manifestation than bilateral. Isotopic and archaeological evidence indicates that the individuals at Kellis maintained an agricultural subsistence regime, and that the males within the population may have been highly mobile migrating to and from the Dakhleh Oasis. Subsistence agriculture has its necessary physical demands which may have been a contributory factor to OA rates. Males show higher OA rates than females throughout the joints of the legs. Sexual dimorphism of OA for the hips is suggestive of sexual divisions of labor. OA of the knees lacks sexual dimorphism therefore the knee joint complex of males and females were likely subjected to similar levels of mechanical loading. It can be concluded based on the OA data that males and females exhibit similar activity, or biomechanical stress levels in the knee joint complexes. Males exhibit significantly higher pathological manifestation of OA in the hip joint complexes, indicative of higher levels of mechanical loading in the hip joint complex which can theoretically be attributed to sexual divisions of labor or perhaps terrestrial mobility.

Show moreRheumatoid arthritis (RA) is a chronic autoimmune disease that often results in inflammation, pain, fatigue, functional impairment, and psychosocial difficulties. The current study examines the effectiveness, feasibility, and sustainability of an interdisciplinary chronic pain intervention for patients with RA. Wearable fitness trackers were incorporated into the intervention and objectively measured participant physical activity. A total of 44 participants received the intervention and completed outcome measures. Results supported improvements across multiple domains at the end of treatment and at 4-week follow-up compared to treatment baseline. Mixed multilevel repeated measures modeling revealed significant overall improvements in many primary (i.e., self-efficacy for managing chronic disease, pain intensity, pain interference, depression, and health-related quality of life), secondary (i.e., physical functioning, overall quality of life, and chronic pain acceptance), and in an objective measure of physical activity (i.e., average steps per day). Effect sizes were generally small to medium and were similar to or better than those reported in meta-analyses. Patients with comorbid fibromyalgia syndrome recorded significantly worse scores across measures, but showed steady improvement throughout the intervention. Mixed-method analysis suggested that patients were interested in and satisfied with the intervention. Implications for optimization and long-term sustainability are discussed.

Show moreThis purpose of the study is to examine the difference in the health-related quality of life (HRQOL) between individuals who suffer from physician-diagnosed arthritis compared with individuals who do not suffer from physician-diagnosed arthritis in a population of university students, faculty, and staff. The study sampled from a population of students, faculty, and staff at the University of Central Florida. Through the implantation of a cross-sectional ecological design, differences between the two groups were measured with a survey that measures health-related quality of life, such as the 36-Item Short Form Health Survey (SF-36). The SF-36 questionnaire was distributed to subjects through a campus-wide email system and was administered through Qualtrics, an online survey program. Literature suggests lower SF-36 scores for individuals suffering from arthritis, but is lacking in investigating the effect of arthritis on college-aged students, particularly within the 18-24 age group. The study aims to close this gap in the literature. SPSS software was used to analyze results through tests of association, like ANOVA, which measured differences in the SF-36 scores of subjects with physician-diagnosed arthritis and subjects without physician-diagnosed arthritis. Results showed a significant difference in the HR-QOL scores between individuals with arthritis and individuals without arthritis, as well as age, gender, ethnicity, and the presence of joint pain.

Both genetic pre-disposition and potential environmental triggers are shared between Rheumatoid arthritis (RA) and Crohn's disease (CD). We hypothesized that single nucleotide polymorphisms (SNPs) in the negative T-cell regulators Protein Tyrosine Phosphatase Non-receptor type 2 and 22 (PTPN2/22) lead to a dysregulated immune response as seen in RA and CD. To test the hypothesis, peripheral leukocytes samples from 204 consented subjects were TaqMan genotyped for 9 SNPs in PTPN2/22. The SNPs...
Show moreBoth genetic pre-disposition and potential environmental triggers are shared between Rheumatoid arthritis (RA) and Crohn's disease (CD). We hypothesized that single nucleotide polymorphisms (SNPs) in the negative T-cell regulators Protein Tyrosine Phosphatase Non-receptor type 2 and 22 (PTPN2/22) lead to a dysregulated immune response as seen in RA and CD. To test the hypothesis, peripheral leukocytes samples from 204 consented subjects were TaqMan genotyped for 9 SNPs in PTPN2/22. The SNPs effect on PTPN2/22 and IFN-y expression was determined using RT-PCR. Blood samples were analyzed for the Mycobacterium avium subspecies paratuberculosis (MAP) IS900 gene by nPCR. T-cell proliferation and response to phytohematoagglutonin (PHA) mitogen and MAP cell lysate were determined by BrdU proliferation assay. Out of 9 SNPs, SNP alleles of PTPN2:rs478582 occurred in 79% RA compared to 60% control (p-values ? 0.05). SNP alleles of PTPN22:rs2476601 occurred in 29% RA compared to 6% control (p-values ? 0.05). For the haplotype combination of PTPN2:rs478582/PTPN22rs2476601, 21.4% RA had both SNPs (C-A) compared to 2.4% control (p-values ? 0.05). PTPN2/22 expression in RA was decreased by an average of 1.2 fold. PTPN2:rs478582 upregulated IFN-y in RA by an average of 1.5 fold. Combined PTPN2:rs478582/PTPN22:rs2476601 increased T-cell proliferation by an average of 2.7 fold when treated with PHA. MAP DNA was detected in 34% RA compared to 8% controls (p-values ? 0.05), where samples with PTPN2:rs478582 and/or PTPN22:rs2476601 were more MAP positive. PTPN2:rs478582/PTPN22:rs2476601 together with MAP infection significantly increased T-cell response and IFN-y expression in RA samples. The same experimental approach was followed on blood samples from CD patients. Both PTPN2:rs478582/PTPN22:rs2476601 affected PTPN2/22 and IFN-y expression along with T-cell proliferation significantly more than in RA. MAP DNA was detected in 64% of CD. This is the first study to report the correlation between SNPs in PTPN2/22, IFN-y expression and MAP in autoimmune disease.
