ABSTRACTWhile the physical correlates of knee osteoarthritis are well documented, less well documented are aspects of psychological functioning that may affect overall health and functional status. This paper describes the findings of a cross-sectional analysis that examined the strength of the relationship between selected psychological factors and the walking ability of adults with knee joint osteoarthritis. The variables assessed were pain, depression, levels of self-efficacy for pain and other-symptoms management, walking endurance, walking speed, and perceived exertion when walking. The sample, including 57 persons with unilateral and 43 persons with bilateral radiographic and symptomatic knee osteoarthritis, mean age, 69.9 ± 1 years, underwent standard assessment procedures on a single test occasion using several validated questionnaires and a series of walking tests on level ground. Bivariate and multiple regression analyses revealed that (a) higher pain and other-symptoms self-efficacy scores were associated with lower levels of pain (r= −0.29, −0.20.), perceived exertion during a walking task (r= −0.29, −0.31), and depression scores (r= −0.46, −0.54) (p< 0.001); (b) subjects with higher levels of self-efficacy for managing symptoms other than pain also recorded faster and fast speed walking velocities than those with lower self-efficacy scores (r= 0.30, 0.31) (p< 0.001); (c) self-efficacy for pain was the strongest predictor of pain intensity, and self-efficacy for symptom management was the strongest predictor of perceived exertion during walking, depression, and pain self-efficacy. Although no cause–effect relationship can be deduced from a cross-sectional analysis, these data imply that efforts to heighten self-efficacy for pain and other-symptoms management may influence the affective status, function, and effort-related perceptions of people with knee osteoarthritis quite significantly.

Background: Canes have been recommended as walking aids for knee osteoarthritis to reduce the loading on the affected knee. Patients are usually recommended to hold the cane in the contralateral hand to the affected knee. Nevertheless, some patients prefer to hold the cane ipsilateral to the affected knee. However, the effect of using ipsilateral or contralateral tripod cane on functional mobility in patients with knee osteoarthritis is still unknown Objective: To compare the immediate effect of ipsilateral and contralateral tripod cane usage on functional mobility in patients with symptomatic knee osteoarthritis Method: This cross-sectional study involved 30 overweight or obese patients with symptomatic unilateral or bilateral knee osteoarthritis (Kellgren Lawrence grade 2 and 3) who never use a cane. Functional mobility was evaluated with Time Up and Go test in three conditions; without walking aid, with tripod cane contralateral and ipsilateral to the more painful knee. Results: The TUG time of aid-free walking is 4.75 (p < 0.001, 95% CI 3.79 - 5.71) seconds faster than ipsilateral cane use and 6.69 (p < 0.001, 95%CI 5.35 - 8.03) seconds faster than contralateral cane use. The TUG time of ipsilateral cane use is 1,94 (95% CI, 1.13 - 2.79) seconds faster than contralateral. Conclusion: Patients with symptomatic knee OA who use tripod cane ipsilateral to the more painful knee have higher functional mobility than the contralateral.

Abstract Background Pruritus is a common and often distressing symptom in patients with chronic kidney disease. Though the pathogenesis of uremic pruritus remains poorly understood, systemic inflammation has presented itself as one of the possible explanations. High blood lead levels (BLLs) have been noted to be associated with inflammation and poor nutritional status in hemodialysis patients. Our aim is to study the relation between blood lead levels and uremic pruritus. This is a cross-sectional study that enrolled 50 patients; all were on regular hemodialysis 3 times per week for at least 6 months. Patients were divided into 2 groups, group 1 (n =10) with no pruritus and group 2 (n=40) with varying degrees of pruritus. Group 2 was further divided according to intensity of pruritus by visual analog score (VAS) into mild (n=10), moderate (n=20), and severe pruritus (n=10). Results There was a significant difference in serum lead levels and ferritin levels between groups 1 and 2 (p value < 0.01 and < 0.05, respectively). There was a statistically significant difference in serum lead levels in the groups with varying intensity of pruritus, having higher serum lead levels in patients who exhibited severe pruritus (p value < 0.005) Moreover, a statistically significant relation between elevated blood lead levels and the duration of dialysis was observed in this study. Conclusion Uremic pruritus is a multi-factorial phenomenon, and our study showed that blood lead levels in hemodialysis patients might be associated with increased intensity of pruritus.

The Mean

Blood lead levels were determined on 24 mothers during labor and on the blood of their newborn offspring. The mean value for the mother's blood lead was 13.2 µg/100 gm (range 10 to 20) and for the cord blood 12.3 (range 10 to 20) µg/100 gm whole blood. These levels are lower than "normal" blood lead standards usually accepted in the diagnosis and treatment of childhood lead poisoning.
