"This Life is Normal for Me": A Study of Everyday Life Experiences and Coping Strategies of Live-in Carers in Taiwan.

Recruiting migrant live-in carers has become the main strategy to address the rapid increase in the number of older persons with intensive care needs in many parts of the developed world. This is also the case in northern Taiwan, where this study took place. Thirteen live-in carers from Indonesia and the Philippines were interviewed in the fall of 2019. In this article, we discuss their two main coping strategies: a) "accepting destiny", which refers to carers accepting their life and viewing their role as a live-in carer as a job that allowed them to meet their parents' expectations of financial support; and b) "connecting to significant others", which is the most important way carers found motivation to keep going. However, despite their coping strategies, working as a live-in carer was experienced as a challenging and precarious lifestyle. In the conclusion, we discuss how professional social workers in collaboration with decision-makers and non-governmental organizations in Taiwan could contribute to fostering a system that would support live-in carers in ways that allow them, and the older persons they care for, to thrive.

Nonsurgical Versus Surgical Management of Femoroacetabular Impingement: What Does the Current Best Evidence Tell Us.

Controversy exists as to the management of femoroacetabular impingement (FAI). When nonsurgical management of symptomatic FAI fails, surgical management is generally indicated. However, many groups with a stake in patient care (particularly payors) have insisted on higher levels of evidence. Recently, there have been several Level I studies published, comparing physical therapy (PT) with hip arthroscopy in the management of symptomatic FAI. All of these studies have used outcomes tools developed and validated for patients with nonarthritic hip pain (the International Hip Outcome Tool). Most highest level evidence confirms that although patients with FAI do benefit from PT, patients who undergo surgical management for FAI with hip arthroscopy benefit more than those who undergo PT (mean difference in the International Hip Outcome Tool 6.8 [minimal clinically important difference 6.1], P = 0.0093). Future large prospective studies are needed to evaluate the effect on the outcomes when there is a delay in surgical management in symptomatic individuals, assess whether FAI surgery prevents or delays osteoarthritis, and determine the role of other advanced surgical techniques.

Superior Capsular Reconstruction: A Systematic Review of Surgical Techniques and Clinical Outcomes.

PURPOSE: To evaluate surgical techniques and clinical outcomes of arthroscopic superior capsular reconstruction (SCR) for the treatment of massive irreparable rotator cuff tears. METHODS: A systematic review was registered with PROSPERO and performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The PubMed, Scopus, and Cochrane databases were searched. Studies investigating SCR with reported surgical techniques were included. Animal studies, cadaveric studies, review studies, and letters to the editor were excluded. The technical aspects of the surgical techniques for SCR were analyzed in each article, which included graft type, glenoid fixation method, greater tuberosity fixation method, graft passage technique, suture management, margin convergence, concomitant procedures, and postoperative rehabilitation protocol. Clinical outcomes, when available, were also analyzed. RESULTS: We screened 365 articles, of which 29 described surgical techniques for SCR. According to the Modified Coleman Methodology Score, 24 articles were rated as poor (score < 55), 4 were rated as fair (score between 55 and 69), and 1 was rated as good (score between 70 and 84), with an average score of 25.8 ± 20.9. The most commonly performed technique for SCR used the following: an acellular dermal allograft, 2 biocomposite suture anchors for glenoid fixation, transosseous-equivalent double-row suture anchor fixation for greater tuberosity fixation with 2 biocomposite medial-row anchors and 2 biocomposite lateral-row anchors, the double-pulley technique combined with an arthroscopic grasper and/or pull suture to pass the graft into the shoulder, the performance of both anterior and posterior margin convergence, and a native rotator cuff repair when possible. Only 8 studies reported clinical outcomes, and they showed that SCR provides significant improvement in patient-reported outcomes, significant improvement in shoulder range of motion, variable graft failure rates, low complication rates, and variable reoperation rates. There were no studies comparing outcomes among the various surgical techniques. CONCLUSIONS: Many surgical techniques exist for arthroscopic SCR. However, no superior technique was shown because there were no studies comparing clinical outcomes among these various techniques. LEVEL OF EVIDENCE: Level V, systematic review of Level III, IV, and V studies.

Inflammatory "adiposopathy" in major amputation patients.

BACKGROUND: Much has been made of obesity's health impact, largely founded on data regarding patient weight and circulating adipose-derived mediator levels. Paradoxically, a "healthy obese" state exists, but substantial knowledge gaps also exist regarding human adipose-phenotype determinants. Surgical major amputation (AMP) patients are the "sickest-of-the-sick." Conversely, elective knee replacement (TKR) is reserved for patients who expect continued health and longevity. To delineate human adipose biology variability and clinical determinants, we studied fresh subcutaneous adipose from AMP patients, using TKR patients as controls. We hypothesized that AMP patients would display a pro-inflammatory adipokine signature, and that certain clinical conditions (diabetes, hypertension, hyperlipidemia, high BMI, uremia) would independently drive elevated adipose inflammation. METHODS: AMP (n = 29) and TKR (n = 20) adipose tissue samples and clinical data were collected prospectively, and protein was isolated and analyzed for 8 adipose-related mediators. Statistical analyses included Wilcoxon's rank sum test, Fisher's exact test, and multiple linear regression modeling of clinical parameter predictors of mediator expression. RESULTS: Interleukin-(IL)-6, IL-8, leptin, resistin, and PAI-1 were differentially expressed (up to 200-fold) between AMP/TKR cohorts. Key clinical parameters that associated with protein levels of adipose phenotype included age, gender, hypertension, hyperlipidemia, congestive heart failure, cerebrovascular disease, renal disease, and warfarin, statin, and insulin use. BMI failed to be predictive. CONCLUSIONS: AMP patients display adiposopathy with a pro-inflammatory adipose phenotypic signature compared with TKR controls. BMI fails to predict phenotype, yet other clinical conditions, such as age, hyperlipidemia, and renal insufficiency, do drive adipokine expression. Understanding human adipose phenotypic determinants stands as a fundamental priority when future studies dissect the interplay between adipose biology and surgical diseases/outcomes.

Attenuated adiposopathy in perivascular adipose tissue compared with subcutaneous human adipose tissue.

BACKGROUND: We hypothesized that human perivascular and subcutaneous adipose tissues hold distinct phenotypic signatures. We also evaluated the impact of clinical parameters on the adipose phenotype. Our overall goal is to understand the determinants of adipose biology so that this tissue can be manipulated therapeutically to lessen peripheral vascular disease. METHODS: Perivascular and subcutaneous adipose tissues were collected from patients undergoing lower-extremity amputation (n = 27) and protein assayed for proinflammatory mediators (ie, interleukin 6, interleukin 8, leptin, tumor necrosis factor α, monocyte chemoattractant protein-1, and resistin), atheroprotective adiponectin, and the fibrinolysis inhibitor plasminogen activator inhibitor-1. RESULTS: Leptin (2.7-fold, P = .015), TNF-α (2.2-fold, P = .013), MCP-1 (1.5-fold, P = .047), and adiponectin (1.8-fold, P = .004) were more abundant in subcutaneous vs perivascular adipose tissue. Age positively correlated with perivascular adipose tissue PAI-1 expression (ß = .64, P = .042), and hyperlipidemia negatively correlated with perivascular adiponectin (ß = -1.18, P = .039). CONCLUSIONS: Human perivascular and subcutaneous adipose tissues hold distinct phenotypic signatures. In amputation patients, the subcutaneous adipose tissue proinflammatory phenotype was relatively attenuated in perivascular adipose tissue.

Murine ultrasound imaging for circumferential strain analyses in the angiotensin II abdominal aortic aneurysm model.

OBJECTIVE: The underlying causes of abdominal aortic aneurysms (AAAs) remain obscure, although research tools such as the angiotensin II (Ang II) apolipoprotein E-deficient (apoE(-/-)) mouse model have aided investigations. Longitudinal imaging and determination of biomechanical forces in this small-scale model have been difficult. We hypothesized that high-frequency ultrasound biomicroscopy combined with speckle-tracking analytical strategies can be used to define the role of circumferential mechanical strain in AAA formation in the Ang II/apoE(-/-) mouse model of AAAs. We simultaneously examined dietary perturbations that might impact the biomechanical properties of the aortic wall, hypothesizing that the generalized inflammatory phenotype associated with diet-induced obesity would be associated with accelerated loss of circumferential strain and aneurysmal aortic degeneration. METHODS: Receiving either a 60 kcal% fat Western diet or standard 10 kcal% fat normal chow, Ang II-treated apoE(-/-) mice (n = 34) underwent sequential aortic duplex ultrasound scan imaging (Vevo 2100 System; VisualSonics, Toronto, Ontario, Canada) of their entire aorta. Circumferential strains were calculated using speckle-tracking algorithms and a custom MatLab analysis. RESULTS: Decreased strains in all aortic locations after just 3 days of Ang II treatment were observed, and this effect progressed during the 4-week observation period. Anatomic segments along the aorta impacted wall strain (baseline highest in ascending aorta; P < .05), whereas diet did not. At 2 and 4 weeks, there was the largest progressive decrease in strain in the paravisceral/supraceliac aorta (P < .05), which was the segment most likely to be involved in aneurysm formation in this model. CONCLUSIONS: In the Ang II/apoE(-/-) aneurysm model, the aorta significantly stiffens (with decreased strain) shortly after Ang II infusion, and this progressively continues through the next 4 weeks. High-fat feeding did not have an impact on wall strain. Delineation of biomechanical factors and AAA morphology via duplex scan and speckle-tracking algorithms in mouse models should accelerate insights into human AAAs.
