Structural interaction between bone and implants due to arthroplasty of the first metatarsophalangeal joint

Background: Currently, the metatarsophalangeal joint replacement through a restorative arthroplasty, where implants are used, is a viable invasive surgical medical procedure in the treatment of severe cases of osteoarthritis in this joint, better known as hallux rigidus. However, few things are known about the postoperative complications that implants can cause on the joint, like Swanson and Tornier implants.Research in this field can provide a valuable information that would help the specialist surgeon in the decision-making during the selection of the more suitable joint implant in each patient, as well as the redesign of the devices, to make them more efficient, durable and biocompatible with the human body. Methods: The aim of this work is to perform a structural biomechanical analysis of a restorative arthroplasty of the first metatarsophalangeal joint, and to analyze the interaction between bone and medical grade silicone implants. For that, a simulation of a foot with Swanson and Tornier joint implants were performed to evaluate the stress/strain distribution during a critical stage (toe-off). Results and conclusions: Principal stresses obtained for the first metatarsal with both implants suggest that failure is induced in this bone because, values exceed (up to 136.84% for Swanson model) the tensile strength reported for phalange trabecular bone, which may be related to osteolysis. Stress and strain values obtained in this work suggest that arthroplasty surgery with Swanson implant is more likely to cause postoperative complications versus Tornier implant

Impact of footwear and foot deformities in patients with Parkinson?s disease: A case-series study

Background: Parkinson's disease (PD) is a common and complex neurological problem. Gait abnormalities are frequent in PD patients, and this increases the risk of falls. However, little is known about foot deformities and footwear in this vulnerable population. Here we investigate whether patients with PD use an appropriate shoe size and know if they have foot deformities or alterations. Methodology: A study of a series of observational descriptive cases in a convenience sample (n = 53 patients) diagnosed with Parkinson's disease. One trained investigator evaluated foot and ankle health. The footwear and foot measurements were obtained using a Brannock device. Results: The podiatric examination and footwear examination detected a high presence of podiatric pathologies and inappropriate footwear. This has a negative impact on the quality of life of these patients. Conclusions: This research detected an elevated number of people with foot deformities or alterations. Moreover, a high proportion of participants with PD wear inadequate footwear (in length, width, or both)

POWERbreathe® Inspiratory Muscle Training in Amyotrophic Lateral Sclerosis.

Inspiratory muscle training may benefit respiratory function, cardiocirculatory parameters, quality of life and functionality in neuromuscular diseases. This pilot study aimed to demonstrate the POWERbreathe® inspiratory muscle training effects on maximum inspiratory pressure (PImax), heart rate (HR) and HR variability, as well as the quality of life impairment and functionality in patients with Amyotrophic Lateral Sclerosis (ALS). A pilot single-blinded, non-randomized controlled clinical trial was carried out. A total of 20T ALS patients were enrolled and divided into experimental (n = 10) and control (n = 10) groups. The experimental group received POWERbreathe® inspiratory muscle training in conjunction with usual care, and the control group received only usual care for 8 weeks. PImax (measured by POWERbreathe® KH1), HR and HR variability (evaluated by Polar H7), quality of life impairment [measured by the Amyotrophic Lateral Sclerosis Assessment Questionnaire—40 items (ALSAQ-40)] and functionality [assessed by the ALS Functional Rating Scale Revised (ALSFRS-R)] were collected at baseline and after 8 weeks of intervention. We detected statistically significant differences (p < 0.05) with an effect size ranging from medium to large (Cohen’s d = 0.72–1.37); relative to the control group, the experimental group had an increased PImax (mean difference = 10.80 cm H2O; 95% CI = 3.42–18.17) and ALSFRS-R score (mean difference = 5.30 points; 95% CI = −0.03–10.63) and reduced HR (mean difference = −8.80 beats-per-minute; 95% CI = −20.27–2.67) and R-R interval (mean difference = 78.30 ms; 95% CI = 2.89–153.70). POWERbreathe® inspiratory muscle training, in addition to usual care, may improve inspiratory strength and heart rate in patients with ALS. These results encourage larger and longer trials investigating potential clinically relevant benefits of inspiratory muscle training to these patients over the disease course.post-print6421 K

We evaluated and compared the impact on quality of life (QoL) related to foot health and general health between males and females with PF. Methods: In this cross-sectional descriptive study, patients with PF were recruited from a podiatry clinic. Physical examination, sociodemographic data, and the self-reported Foot Health Status Questionnaire (FHSQ) were recorded. The FHSQ has three sections and provides two composite scores from 0 to 100. Higher scores (close to 100) reflect better QoL related to foot health and health in general; lower scores (close to 0) denote a worse QoL related to these health items. Results: One hundred patients (49 males [42.38 &plusmn; 14.065 years old] and 51 females [43.90 &plusmn; 14.305 years old]) were recruited. Section one of the FHSQ evaluates four foot domains, and significant differences (P&lt;0.05) were shown for foot pain and footwear, with males having higher scores than females, but not for foot function and general foot health (P&gt;0.05). Section two assesses four domains of general wellbeing, and significant differences (P&lt;0.05) were shown for overall health, physical function, social capacity, and vigor, with males having higher scores than females. Conclusion: Females with PF showed a worse health-related QoL for foot pain, foot function, footwear, and general foot health than males. A better health-related QoL was also shown for males with PF than for females with regard to general health, physical activity, social capacity, and vigor.

Methods: A case&ndash;control observational study was carried out following the Strengthening the Reporting of Observational Studies in Epidemiology criteria. A total of 100 older adults with a mean age of 74.39&plusmn;6.02 years were recruited at an outpatient clinic; 50 of these subjects had LTD (case group) and 50 subjects were without any foot conditions (control group). Presence of LTD was determined in both feet using the Kelikian push-up test, and the Foot Health Status Questionnaire scores were self-reported.Results: The case group showed lower scores in quality of life in relation to health in general and to foot health specifically. Statistically significant differences (p&lt;0.05) between case and control groups were shown by means of the Wicoxon test.Conclusion: A negative impact in quality of life in relation to foot health should be considered in older adults with LTD, regardless of gender.

The aim of this study was to determine the Beck Depression Inventory (BDI) scores in participants with nonspecific LBP and no-pain by age distribution.Methods: A case&ndash;control study was carried out following the Strengthening the Reporting of Observational Studies in Epidemiology criteria. A sample of 332 participants, divided into the following age categories: 19&ndash;24 (n=11), 25&ndash;39 (n=66), 40&ndash;64 (n=90), 65&ndash;79 (n=124), and &ge;80 (n=41) years was recruited from domiciliary visits and an outpatient clinic. The BDI scores were self-reported in participants with nonspecific acute or subacute (&le;3 months) LBP (n=166) and no-pain (n=166).Results: The BDI scores, mean &plusmn; standard deviation, showed statistically significant differences (p&lt;0.001) between participants with nonspecific acute or subacute LBP (9.590&plusmn;6.370) and no-pain (5.825&plusmn;5.113). Significantly higher BDI scores were obtained from participants with nonspecific acute and subacute LBP in those aged 40&ndash;64 years (p&lt;0.001; 9.140&plusmn;6.074 vs 4.700&plusmn;3.777) and 65&ndash;79 years (p&lt;0.001; 10.672&plusmn;6.126 vs 6.210&plusmn;5.052). Differences were not significant in younger patients aged 19&ndash;24 (p=0.494; 5.000&plusmn;2.646 vs 8.250&plusmn;7.498), 25&ndash;39 (p=0.138; 5.440&plusmn;5.245 vs 3.634&plusmn;4.397), and in those aged &ge;80 years (p=0.094; 13.625&plusmn;6.1331 vs 10.440&plusmn;5.591).Conclusion: Participants with nonspecific acute and subacute LBP present higher BDI depression scores, influenced by age distribution. Specifically, patients in the age range from 40 to 80&nbsp;years with LBP could require more psychological care in addition to any medical or physical therapy. Nevertheless, physical factors, different outcomes, and larger sample size should be considered in future studies. Keywords: depression, low back pain, musculoskeletal diseases, age distributio

University of Extremadura, 6Nursing and Physical Therapy Department, Institute of Biomedicine (IBIOMED), Universidad de Le&oacute;n, Ponferrada, Le&oacute;n, 7Research, Health and Podiatry Unit, Department of Health Sciences, Faculty of Nursing and Podiatry, Universidade da Coru&ntilde;a, Spain Purpose: The aim of this study was to analyze and compare foot health and general health in a sample of women divided into two groups: 1) those with breast cancer and undergoing chemotherapy treatment and 2) healthy women without breast cancer and with normalized reference values.Methods: A case&ndash;control observational study was performed. Two-hundred women with a mean age of 51.00&plusmn;8.75 years were recruited from podiatric medicine and surgery clinics from the University of Extremadura (Plasencia, Spain) and the Hospital Infanta Cristina (Badajoz, Spain). The women were divided into case and control groups (undergoing chemotherapy treatment and healthy women, respectively). The Foot Health Status Questionnaire was used to assess foot health domain scores.Results: Significant differences between both groups were seen for foot pain (P=0.003), foot function (P&lt;0.001), physical activity (P&lt;0.001), social capacity (P&lt;0.001), and vigor (P=0.001). The remaining domains (footwear, general health, and foot health) did not show significant differences between the two groups (P&ge;0.01).Conclusion: Women with breast cancer presented a lower foot health-related quality of life. Clinical aspects with emphasis on foot pain and disability were increased. Furthermore, physical activity, social capacity, and vigor were affected. Therefore, general health care and foot problem prevention for breast cancer survivors should be given more consideration. Keywords: breast cancer, chemotherapy, foot injury, quality of lif
