The changes of all variables were compared between the two groups.<br /><br /> The mean ROM of the adjacent segment increased by 3.6 degree in group 1 and conversely decreased by 2.8 degree in group 2 (P = 0.002). The mean ROM increase of the next segment was significantly greater in group 2 than in group 1 (4.5 vs. 1.2 degree, P = 0.016). The osteophyte growth and the progression of listhesis at the next segment were significantly greater in group 2 (P &lt; 0.05). Disc height of the next segment significantly decreased in group 2, but did not change in group 1.<br /><br /> Severe ALOD (grade 2-3) following anterior cervical fusion significantly reduced ROM at the affected segment and conversely increased motion at the next segment. This increased motion probably accelerated the degeneration of the next-level disc.<br /><br /> 3.<br /><br />3.<br /><br /> Below-the-knee amputation (BKA) is relatively common among patients with vascular disease, infection, trauma, or neoplastic disease. Many BKAs are performed in patients with incompletely treated medical comorbidities, and some are performed in patients with acute high-energy trauma or crush injuries, malignant neoplasm undergoing time-sensitive limb removal, and diabetes with active infection or sepsis. Consequently, revision is common. Prior studies of outcomes after BKA, including several based on the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database, have follow-up periods that do not cover the entire at-risk period.<br /><br /> (1) What is the survivorship free from unplanned reoperation within 1 year of BKA? (2) What patient characteristics are associated with reoperation within 1 year of BKA?<br /><br /> We retrospectively studied all BKAs performed by the orthopaedic surgery service at a Level 1 trauma center from 2008 to 2018, as identified by Current Procedural Terminologyr risk for reoperation than currently reported in studies that use 30-day postoperative follow-up periods. Clinicians should critically assess whether BKA is necessary, especially in patients with uncontrolled diabetes assessed by hyperglycemia. Before planned BKA, patients should have documented glycemic control to minimize the odds of reoperation. Because many of this study's limitations were due to its retrospective single center design, we recommend that future work cover a clinically appropriate surveillance period using a larger cohort such as a national database and/or employ a prospective design.<br /><br /> Level III, therapeutic study.<br /><br />Level III, therapeutic study.<br /><br /> Critical access hospitals (CAHs) play an important role in providing access to care for many patients in rural communities. Prior studies have shown that these facilities are able to provide timely and quality care for patients who undergo various elective and emergency general surgical procedures. However, little is known about the quality and reimbursement of surgical care for patients undergoing surgery for hip fractures at CAHs compared with non-CAH facilities.<br /><br /> Are there any differences in 90-day complications, readmissions, mortality, and Medicare payments between patients undergoing surgery for hip fractures at CAHs and those undergoing surgery at non-CAHs?<br /><br /> The 2005 to 2014 Medicare 100% Standard Analytical Files were queried using ICD-9 procedure codes to identify Medicare-eligible beneficiaries undergoing open reduction and internal fixation (79.15, 79.35, and 78.55), hemiarthroplasty (81.52), and THA (81.51) for isolated closed hip fractures. This database was selected because the claims capturose who had surgery at non-CAHs, even though Medicare reimbursements were lower as well. Although there may be some degree of patient selection at CAHs, these facilities appear to provide high-value care to rural communities. These findings provide evidence for policymakers evaluating the impact of the CAH program and allocating funding resources, as well as for community members seeking emergent care at local CAH facilities.<br /><br /> Level III, therapeutic study.<br /><br />Level III, therapeutic study.<br /><br /> Arterial stiffness, namely pulse wave velocity (PWV), is an emerging biomarker in the assessment of vascular health. This meta-analysis aims to determine the effects of exercise training on PWV in patients with hypertension, and to identify the possible moderator variables (e.g. type of exercise) of the effect of exercise on PWV.<br /><br /> MEDLINE, EMBASE, Cochrane and Web of Science were searched up until July 2019 for randomized controlled trials assessing the effect of exercise interventions lasting 4 or more weeks on PWV in adults with hypertension. Random-effects modelling was used to compare changes from pre to postintervention in PWV between exercise and control groups. Data were reported as weighted mean difference (WMD) and 95% confidence interval (95% CI).

PWV was significantly reduced by exercise training [(WMD (95% CI) = -0.76 m/s (-1.05 to -0.47)]. Analysis of moderator variables showed that aerobic exercise [WMD (95% CI) = -0.70 m/s (-1.20 to -0.19)], combined exercise [WMD (95% CI) = -0.74 m/s (-1.41 to -0.08)] and isometric resistance exercise [WMD (95% CI) = -0.98 m/s (-1.24 to -0.73)] reduced PWV. There was no significant reduction in PWV in participants undertaking dynamic resistance training [WMD (95% CI) = -0.58 (-1.58 to 0.42)].<br /><br /> This meta-analysis supports that exercise interventions based on aerobic, combined or isometric exercise are suitable to improve PWV in adults with hypertension.<br /><br />This meta-analysis supports that exercise interventions based on aerobic, combined or isometric exercise are suitable to improve PWV in adults with hypertension.<br /><br /> To clarify the mechanisms of the renal protective effects of exercise training, we examined the effects of exercise training on the renal interstitial fibrosis and renin-angiotensin system (RAS) in rats with chronic renal failure.<br /><br /> Six-week-old male Sprague-Dawley rats were divided into three groups sham operation; 5/6 nephrectomy + sedentary; 5/6 nephrectomy + exercise training. The 5/6 nephrectomy + exercise training group underwent treadmill running (20 m/min, 60 min/day, 5 days/week). After 12 weeks, renal function, histology and protein expression of collagen type I, transforming growth factor-β1 (TGF-β1), matrix metalloproteinase (MMP), tissue inhibitors of metalloproteinase (TIMP) and RAS components in the renal cortex were examined.<br /><br /> Exercise training ameliorated the 5/6 nephrectomy-induced hypertension, proteinuria, renal dysfunction, glomerular sclerosis and renal interstitial fibrosis. 5/6 Nephrectomy increased the expression of collagen type I, TGF-β1, MMP-2, MMP-9, TIMP-1, angiotensinogen, angiotensin-converting enzyme (ACE), (pro)renin receptor and angiotensin II type 1 receptor, and exercise training inhibited the 5/6 nephrectomy-increased expression of collagen type I, TGF-β1, TIMP-1, angiotensinogen and ACE expressions.
