Systematic review: conservative treatments for secondary lymphedema

<p>Abstract</p> <p>Background</p> <p>Several conservative (i.e., nonpharmacologic, nonsurgical) treatments exist for secondary lymphedema. The optimal treatment is unknown. We examined the effectiveness of conservative treatments for secondary lymphedema, as well as harms related to these treatments.</p> <p>Methods</p> <p>We searched MEDLINE^®, EMBASE^®, Cochrane Central Register of Controlled Trials^®, AMED, and CINAHL from 1990 to January 19, 2010. We obtained English- and non-English-language randomized controlled trials or observational studies (with comparison groups) that reported primary effectiveness data on conservative treatments for secondary lymphedema. For English-language studies, we extracted data in tabular form and summarized the tables descriptively. For non-English-language studies, we summarized the results descriptively and discussed similarities with the English-language studies.</p> <p>Results</p> <p>Thirty-six English-language and eight non-English-language studies were included in the review. Most of these studies involved upper-limb lymphedema secondary to breast cancer. Despite lymphedema's chronicity, lengths of follow-up in most studies were under 6 months. Many trial reports contained inadequate descriptions of randomization, blinding, and methods to assess harms. Most observational studies did not control for confounding. Many studies showed that active treatments reduced the size of lymphatic limbs, although extensive between-study heterogeneity in areas such as treatment comparisons and protocols, and outcome measures, prevented us from assessing whether any one treatment was superior. This heterogeneity also precluded us from statistically pooling results. Harms were rare (< 1% incidence) and mostly minor (e.g., headache, arm pain).</p> <p>Conclusions</p> <p>The literature contains no evidence to suggest the most effective treatment for secondary lymphedema. Harms are few and unlikely to cause major clinical problems.</p

Ankle Proprioception Pattern in Women Across Various Trimesters of Pregnancy and Postpartum

Background and Objectives: Ankle foot complex is the part of the body which is in contact with the ground and it is important to have an intact proprioceptive system in order to maintain postural control. Previous study has established that there is significant difference between ankle proprioception in pregnant women in their third trimester and non-pregnant women. There is lack of literature regarding when the ankle does the ankle proprioception gets affected during pregnancy and whether this change reverts back during postpartum and hence this study. Method: A cohort of 70 primiparous women were included in the study and the women were followed through 12th week, 24th week, 32nd week , immediate postpartum and 6 weeks postpartum. The ankle repositioning error was measured using photography method and was analyzed using UTHSCSA Image tool software. Repeated measures ANOVA was used to measure the differences across various time periods. Results: It was found that there was a significant differences (p<0.001) in ankle repositioning error in pregnant women across the trimesters and in the postpartum period and the value did not reach the first trimester value even after six weeks postpartum. Conclusion: Ankle proprioception was significantly affected across the various trimesters of pregnancy with the peak variability observed in the third trimester and the value did not reach back to the first trimester value even after 6 weeks postpartum

The objective of this work was to study the effect of 12-week aerobic exercise training on echocardiographic epicardial adipose tissue thickness (EEATT), body composition and other metabolic parameters in asymptomatic overweight adults. Methods: A total of 170 overweight and mild obese individuals were randomly allocated to 12-week aerobic exercise program (intervention group) or no supervised exercise (control group). The body fat percentage and visceral fat levels were measured by bioelectric impedance analyzer, and blood tests were conducted to measure lipids, fasting blood sugar (FBS) and high-sensitivity C-reactive protein (Hs-CRP). The participants also underwent transthoracic echocardiography to measure EATT. All the outcomes were measured after 12 weeks. Repeated measures were analyzed using ANOVA and Mann&ndash;Whitney U-test were used to analyze the data. Results: EEATT values significantly reduced by &minus;16.24% (3.12&plusmn;1.18 to 2.70&plusmn;1.04, p&lt;0.05) following 12 weeks of aerobic exercise along with a reduction in weight by 2.96% (80.66&plusmn;12.12 to 78.27&plusmn;12.31, p&lt;0.05), body mass index by 3.11% (29.20&plusmn;2.71 to 28.29&plusmn;2.81, p&lt;0.05) and waist circumference by 2.29% (94.82&plusmn;7.23 to 92.64&plusmn;7.33, p&lt;0.05) and improved Hs-CRP values. Conclusion: The 12-week aerobic exercise was found to be effective in reducing EEATT in overweight and mild obese individuals. There was significant improvement in body composition, blood lipids, FBS, Hs-CRP and exercise capacity in intervention group compared to control group.

Exercise intolerance in pulmonary hypertension: mechanism, evaluation and clinical implications.

Introduction: Exercise intolerance in pulmonary hypertension (PH) is a major factor affecting activities of daily living and quality of life. Evaluation strategies (i.e., non-invasive and invasive tests) are integral to providing a comprehensive assessment of clinical and functional status. Despite a growing body of literature on the clinical consequences of PH, there are limited studies discussing the contribution of various physiological systems to exercise intolerance in this patient population. Areas covered: This review, through a search of various databases, describes the physiological basis for exercise intolerance across the various PH etiologies, highlights the various exercise evaluation methods and discusses the rationale for exercise training amongst those diagnosed with PH. Expert commentary: With the growing importance of evaluating exercise capacity in PH (class 1, Level C recommendation), understanding why exercise performance is altered in PH is crucial. Thus, the further study is required for better quality evidence in this area
