A comparison of mobilization and mobilization with movement on pain and range of motion in people with lateral ankle sprain: A randomized clinical trial

BackgroundMaitland and Mulligan mobilization techniques are two manual therapy methods to increase the range of motion following immobility treatment. The present study was conducted to compare two therapeutic methods, namely mobilization and mobilization with movement (MWM), on the pain and range of motion in people with lateral ankle sprain.MethodsA total of 40 individuals with grade two lateral ankle sprain were randomly divided into two groups, including the Maitland's mobilization intervention group, and the Mulligan's mobilization intervention group. Both groups underwent treatment every other day for two consecutive weeks. The pain intensity was measured using the Visual Analogue Scale (VAS), and the ankle dorsiflexion movement range using the Weight Bearing Lunge Test (WBLT) before and one day after the intervention.ResultsThere were no significant differences between the two groups in terms of pain (P = 0.297) and range of motion (P = 0.294) before the intervention. Meanwhile, after the intervention, a significant change was observed in both groups in terms of these variables, which indicates the effectiveness of both interventions (P < 0.001) and the greater effect of the mobilization with movement in reducing pain (P = 0.037) and increasing the range of motion (P = 0.021).ConclusionsBoth techniques significantly improved the range of motion and reduced pain in people with lateral ankle sprain, but Mulligan's technique was significantly more effective among the two, perhaps due to joining active and passive mobilizing tensile forces as well as interaction of afferents and efferents in the reflex arc.     

Outcomes of central hepatectomy versus extended hepatectomy

BackgroundCentral hepatectomy (CH) is more difficult than extended hepatectomy (EH) and is associated with greater morbidity. In this modern era of liver management with aims to prevent post-hepatectomy liver failure (PHLF), there is a need to assess outcomes of CH as a parenchyma-sparing procedure for centrally located liver tumors.MethodsA total of 178 major liver resections performed by specialist surgeons from two Australian tertiary institutions between June 2009 and March 2017 were reviewed. Eleven patients had CH and 24 had EH over this study period. Indications and perioperative outcomes were compared between the groups.ResultsThe main indication for performing CH was colorectal liver metastases. There was no perioperative mortality in the CH group and four (16.7%) in the EH group (P = 0.285). No group differences were found in median operative time [CH vs. EH: 450 min (290–840) vs. 523 min (310–860), P = 0.328], intraoperative blood loss [850 mL (400–1500) vs. 650 mL (100–2000), P = 0.746] or patients requiring intraoperative blood transfusion [1 (9.1%) vs. 7 (30.4%), P = 0.227]. There was a trend towards fewer hepatectomy-specific complications in the CH group [3 (27.3%) vs. 13 (54.2%), P = 0.167], including PHLF (CH vs. EH: 0 vs. 29.2%, P = 0.072). Median length of stay was similar between groups [CH vs. EH: 9 days (5–23) vs. 12 days (4–85), P = 0.244].ConclusionsCH has equivalent postoperative outcomes to EH. There is a trend towards fewer hepatectomy-specific complications, including PHLF. In appropriate patients, CH may be considered as a safe parenchyma-sparing alternative to EH.     

Conditional survival in patients with spontaneous tumor rupture of hepatocellular carcinoma after partial hepatectomy: a propensity score matching analysis

BackgroundSpontaneous tumor rupture (STR) of hepatocellular carcinoma (HCC) is a life-threatening condition. This study investigates the influences of STR on the observed survival and conditional survival of patients received hepatectomy.MethodsA retrospective cohort of patients who underwent hepatectomy from 2009 to 2013 was divided into tumor rupture group and non-rupture group. Propensity score matching (PSM) was used for comparison of the observed survival and conditional survival probabilities between these two groups.Results89 pairs of patients who had comparable background and tumor characteristics were created using PSM analysis. There was significant association between STR and increased risk of OS no matter when before or after PSM (p < 0.01). STR was significantly associated with increased risks of PFS before, while not after PSM. Multivariate Cox regression analyses demonstrated that STR was an independent risk factor associated with OS. There were significant differences in two groups for conditional probabilities of OS and PFS for an additional 6 months and 1 year before PSM, while not after PSM.ConclusionsThis study identified STR but not PFS as an independent risk factor influencing OS, in patients with HCC following hepatectomy. In selected patients with STRHCC, hepatectomy should be performed with acceptable outcomes.

Lumen-apposing metal stent deployment for walled-off necrosis using semi-free hand technique from the intestine

Lumen-apposing metal stent (LAMS) deployment under en- doscopic ultrasonography (EUS) guidance has been used for walled-off necrosis (WON) [1] . Recently, LAMS with electrocautery enhanced delivery system has been developed. One of the advan- tages of this stent is that the stent can be delivered without any dilation devices. However, to prevent stent migration into the in- testinal lumen, it is important that stent delivery system should be inserted within the WON. When the diameter of WON is not large enough to insert stent delivery system, contralateral wall of WON may be injured. To prevent this adverse event, guidewire insertion may be useful after puncturing. In addition, according to the re- cent reports [2–4] , EUS-guided LAMS placement for WON drainage has been performed. We herein described a case of LAMS deploy- ment from the second part of the duodenum using semi-free hand technique.

Effect of Glycemic Index of Breakfast on Energy Intake at Subsequent Meal among Healthy People: A Meta-Analysis

Meals with low glycemic index (GI) may suppress short-term appetite and reduce subsequent food intake compared with high-GI meals. However, no meta-analysis has been conducted to synthesize the evidence. This meta-analytic study was conducted to assess the effect of high- and low-GI breakfast on subsequent short-term food intake. Trials were identified through MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled trials, and manual searches of bibliographies until May 2015. Randomized controlled and cross-over trials comparing the effect of low- with high-GI breakfast on subsequent energy intake among healthy people were included. Nine studies consisting of 11 trials met the inclusion criteria. Only one trial was classified with high methodological quality. A total of 183 participants were involved in the trials. The meta-analytic results revealed no difference in breakfast GI (high-GI vs. low-GI) on subsequent short-term energy intake. In conclusion, it seems that breakfast GI has no effect on short-term energy intake among healthy people. However, high quality studies are still warranted to provide more concrete evidence.
