Comparison of clinical outcome between laparoscopic and open hepatectomy of high difficulty score for hepatocellular carcinoma: a propensity score analysis.

BACKGROUND: Laparoscopic liver resection (LLR) of high difficulty score is technically challenging. There is a lack of clinical evidence to support its applicability in terms of the long-term survival benefits. This study aims to compare clinical outcomes between LLR and the open liver resection of high difficulty score for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: From 2010 to 2020, using Iwate criteria, 424 patients underwent liver resection of high difficulty score by the laparoscopic (n = 65) or open (n = 359) approach. Propensity score (PS) matching was performed between the two groups. Short-term and long-term outcomes were compared between PS-matched groups. Univariate and multivariate analyses were performed to identify prognostic factors affecting survival. RESULTS: The laparoscopic group had significantly fewer severe complications (3% vs. 10.8%), and shorter median hospital stays (6 days vs. 8 days) than the open group. Meanwhile, the long-term oncological outcomes were comparable between the two groups, in terms of the tumor recurrence rate (40% vs. 46.1%), the 5-year overall survival rate (75.4% vs. 76.2%), and the 5-year recurrence-free survival rate (50.3% vs. 53.5%). The high preoperative serum alpha-fetoprotein level, multiple tumors, and severe postoperative complications were the independent poor prognostic factors associated with worse overall survival. The surgical approach (Laparoscopic vs. Open) did not influence the survival. CONCLUSION: LLR of high difficulty score for selected patients with HCC has better short-term outcomes than the open approach. More importantly, it can achieve similar long-term survival outcomes as the open approach.

Comparison of post-hepatectomy long-term survival outcome between non-colorectal non-neuroendocrine and colorectal liver metastases: A population-based propensity-score matching analysis.

BACKGROUND: Hepatectomy is an established treatment for colorectal liver metastasis (CLM) or neuroendocrine liver metastasis. However, its role in non-colorectal non-neuroendocrine liver metastasis (NCNNLM) is controversial. This study aims to compare long-term survival outcomes after hepatectomy between NCNNLM and CLM in a population-based cohort. METHODS: From 2009 to 2018, curative hepatectomy were performed in 964 patients with NCNNLM (n â€‹= â€‹133) or CLM (n â€‹= â€‹831). Propensity score (PS) matching was performed. Short-term and long-term outcomes were compared between PS-matched groups. Univariate and multivariate analyses were performed to identify prognostic factors affecting survival. RESULTS: There were 133 patients in the NCNNLM group and 266 patients in the CLM group. The mortality (1.5 â€‹% vs 1.5 â€‹%) and morbidity (19.5 â€‹% vs 20.3 â€‹%) rates were comparable between the two groups. There was no statistically significant difference in 5-year overall (48.9 â€‹% vs 39.8 â€‹%) and recurrence-free (25.1 â€‹% vs 23.4 â€‹%) survival rates between NCNNLM and CLM groups. A high pre-operative serum bilirubin level, severe postoperative complications and multiple tumors were independent prognostic factors for poor survival. CONCLUSION: Hepatectomy for selected patients with NCNNLM can achieve similar long-term oncological outcomes as those with CLM. High serum bilirubin, severe postoperative complication and multiple tumors are poor prognostic factors for survival.

Does ACE2 mediate the detrimental effect of exposures related to COVID-19 risk: A Mendelian randomization investigation.

OBJECTIVES: Adiposity, smoking, and lower socioeconomic position (SEP) increase COVID-19 risk while the association of vitamin D, blood pressure, and glycemic traits in COVID-19 risk were less clear. Whether angiotensin-converting enzyme 2 (ACE2), the key receptor for SARS-CoV-2, mediates these associations has not been investigated. We conducted a Mendelian randomization study to assess the role of these exposures in COVID-19 and mediation by ACE2. METHODS: We extracted genetic variants strongly related to various exposures (vitamin D, blood pressure, glycemic traits, smoking, adiposity, and educational attainment [SEP proxy]), and ACE2 cis-variants from genome-wide association studies (GWAS, n ranged from 28 204 to 3 037 499) and applied them to GWAS summary statistics of ACE2 (n = 28 204) and COVID-19 (severe, hospitalized, and susceptibility, n ≤ 2 942 817). We used inverse variance weighted as the main analyses, with MR-Egger and weighted median as sensitivity analyses. Mediation analyses were performed based on product of coefficient method. RESULTS: Higher adiposity, lifetime smoking index, and lower educational attainment were consistently associated with higher risk of COVID-19 phenotypes while there was no strong evidence for an association of other exposures in COVID-19 risk. ACE2 partially mediates the detrimental effects of body mass index (ranged from 4.3% to 8.2%), waist-to-hip ratio (ranged from 11.2% to 16.8%), and lower educational attainment (ranged from 4.0% to 7.5%) in COVID-19 phenotypes while ACE2 did not mediate the detrimental effect of smoking. CONCLUSIONS: We provided genetic evidence that reducing ACE2 could partly lower COVID-19 risk amongst people who were overweight/obese or of lower SEP.

Docetaxel, Cisplatin, and 5-FU Triplet Therapy as Conversion Therapy for Locoregionally Advanced Unresectable Esophageal Squamous Cell Carcinoma.

BACKGROUND: The standard treatment for locoregionally advanced unresectable esophageal squamous cell carcinoma was radical chemoradiotherapy. However, the prognosis was modest. Emerging evidence showed the concept of induction chemotherapy with a goal of conversion surgery. METHODS: We reviewed the long-term, clinical outcomes and safety data of induction chemotherapy using docetaxel-cisplatin-5FU (DCF) and subsequent definitive treatment, either surgery or radical chemoradiotherapy (CRT), in locally advanced unresectable esophageal cancer in Queen Mary Hospital, Hong Kong. A total of 47 patients (median age 62 years, male: 41 (87.2%)) with locoregionally advanced unresectable esophageal cancer received induction DCF. The response rate was 65.9% (complete/partial response: n = 31). After induction DCF, 24 patients (41.4%) had radical surgery and 7 (14.9%) had definitive CRT. RESULTS: The median overall survival (mOS) was significantly longer in patients received subsequent surgery compared with those with definitive CRT (mOS: 40.2 vs. 9.1 months, hazard ratio 3.33, 95% confidence interval 1.22-9.07, p = 0.02) and no definitive treatment (mOS: 40.2 vs. 6.3 months, hazard ratio 8.51, 95% confidence interval 3.7-19.73, p < 0.001). Patients who received surgery, female, and those with supraclavicular lymph node involvement had a better OS. Twenty-one patients (44.7%) developed grade 3/4 adverse events during induction DCF, and two died after chemotherapy because of trachea-esophageal fistula complicated with sepsis. Eleven patients who had surgery had postoperative complications and none had postoperative mortality. CONCLUSIONS: Induction DCF and subsequent conversion surgery offered a chance of cure with long-term survival benefit and manageable toxicities in patients with locoregionally advanced unresectable esophageal cancer.

The Impact of Involved Resection Margin on Recurrence and Survival After Pancreaticoduodenectomy for Periampullary Carcinoma, with Emphasis on Pancreatic Head Carcinoma.

BACKGROUND: The supposed adverse effect of involved resection margin during pancreaticoduodenectomy (PD) for periampullary carcinoma or pancreatic head carcinoma (CaP) on long-term oncological outcomes is still inconclusive. METHODS: This is a retrospective study on periampullary carcinoma undergoing PD. Patients with R0 (margin clear) resection were compared to patients with R1 (microscopically directly involved margin) resection. Patients with gross involved margin (R2 resection) were excluded. Long-term oncological outcomes measured included incidence and site of recurrent disease, overall survival (OS) and disease-free survival (DFS). A subgroup analysis was made on patients with CaP. RESULTS: Between January 2003 and December 2019, 203 PD were identified for present study. The incidence of R1 resection was common (12% in periampullary carcinoma and 20% in CaP). In periampullary carcinoma, R1 resection had greater proportion of CaP, lesser proportion of carcinoma of ampulla (CaA), more perineural invasion, more lymph node (LN) metastasis. R1 group had a shorter OS and DFS, but no difference in the incidence and site of recurrent disease. In the subgroup of CaP (91 patients), R1 group did not differ from R0 group except for more LN metastasis. There was no difference in incidence and site of recurrent disease, OS and DFS. On multivariable analysis, R1 resection was not an independent factor for OS and DFS for periampullary carcinoma or for CaP only. CONCLUSION: Involved resection margin was not uncommon. It was not associated with higher incidence of recurrent disease including local recurrence, and was not an independent prognosticator for OS and DFS.

Minimally invasive versus open liver resection for hepatocellular carcinoma: a propensity score matching analysis of 224 patients.

PURPOSE: To compare the peri-operative and long-term survival outcomes of minimally invasive liver resection (MILR) (robotic or laparoscopic) with open liver resection (OLR) in patients with hepatocellular carcinoma (HCC). METHODS: Data of patients who underwent liver resection for HCC were reviewed from a prospectively collected database. Outcomes of MILR were compared with those of OLR. A propensity score matching analysis with a ratio of 1:1 was performed to minimise the potential bias in clinical pathological factors. RESULTS: From January 2003 to December 2017, a total of 705 patients underwent liver resection for HCC. Amongst them, 112 patients received MILR and 593 patients received OLR. After propensity score matching, there were 112 patients in each of the MILR and OLR groups. Patients were matched by age, sex, hepatitis status, presence of cirrhosis, platelet count, albumin level, bilirubin level, alkaline phosphatase (ALP) level, alanine transferase (ALT) level, creatinine level, tumour differentiation, tumour size, tumour number, presence of tumour rupture, presence of vascular invasion, extent of liver resection (minor/major) and difficulty score. The 1-, 3- and 5-year overall survival rates were 94.4%, 90.4% and 82.3% in the MILR group vs 95.4%, 80.5% and 71.8% in the open group (p = 0.240). The 1-, 3- and 5-year disease-free survival rates were 81.0%, 63.1% and 55.8% in the MILR group vs 79.1%, 58.1% and 45.7 in the open group (p = 0.449). The MILR group demonstrated significantly less blood loss (p < 0.001), less blood transfusion (p = 0.004), lower post-operative complications (p < 0.001) and shorter hospital stay (p < 0.001) when compared with the OLR group. CONCLUSIONS: Our data shows MILR yielded superior post-operative outcomes to OLR, with comparable survival outcomes.

Is hepatic resection justified for non-colorectal non-neuroendocrine liver metastases? A systematic review and meta-analysis.

BACKGROUND: Hepatic resection (HR) is effective for colorectal or neuroendocrine liver metastases. However, the role of HR for non-colorectal non-neuroendocrine liver metastases (NCNNLM) is unknown. This study aims to perform a systematic review and meta-analysis on long-term clinical outcomes after HR for NCNNLM. METHODS: electronic search was performed to identify relevant publications using PRISMA and MOOSE guidelines. Primary outcomes were 3- and 5-year overall survival (OS) and disease-free survival (DFS). Secondary outcomes were post-operative morbidity and 30-day mortality. RESULTS: There were 40 selected studies involving 5696 patients with NCNNLM undergone HR. Pooled data analyses showed that the 3- and 5-year OS were 40% (95% CI 0.35-0.46) and 32% (95% CI 0.29-0.36), whereas the 3- and 5-year DFS were 28% (95% CI 0.21-0.36) and 24% (95% CI 0.20-0.30), respectively. The postoperative morbidity rate was 28%, while the 30-day mortality was 2%. Subgroup analysis on HR for gastric cancer liver metastasis revealed the 3-year and 5-year OS of 39% and 25%, respectively. CONCLUSIONS: HR for NCNNLM may achieve satisfactory survival outcome in selected patients with low morbidities and mortalities. However, more concrete evidence from prospective study is warrant in future.

Investigating The Association Between Supraspinatus Tendon Abnormality, Shoulder Pain and Isokinetic Strength in Elite Swimmers: A Cross-Sectional Study.

Shoulder pain is common among elite swimmers due to the tremendous stress over shoulders during swimming. Supraspinatus muscle is one of the major prime movers and stabilizers of shoulder and is highly susceptible to overloading and tendinopathy. An understanding of the relationship between supraspinatus tendon and pain; and between supraspinatus tendon and strength would assist health care practitioners for developing training regime. The objectives of this study are to evaluate 1) the association between structural abnormality of supraspinatus tendon and shoulder pain and 2) the association between structural abnormality of supraspinatus tendon and shoulder strength. We hypothesized that structural abnormality of supraspinatus tendons positively associated with shoulder pain and negatively associated with shoulder muscle strength among elite swimmers. 44 elite swimmers were recruited from the Hong Kong China Swimming Association. Supraspinatus tendon condition was evaluated using diagnostic ultrasound imaging and shoulder internal and external rotation strength was evaluated by the isokinetic dynamometer. Pearson's R was used to study the correlation between shoulder pain and supraspinatus tendon condition and to evaluate the association between isokinetic strength of shoulders and supraspinatus tendon condition. 82 shoulders had supraspinatus tendinopathy or tendon tear (93.18%). However, there was no statistically significant association between structural abnormality of supraspinatus tendon and shoulder pain. The results showed that there was no association between supraspinatus tendon abnormality and shoulder pain and there was a significant correlation between left maximal supraspinatus tendon thickness (LMSTT) and left external rotation/ concentric (LER/Con) and left external rotation/ eccentric (LER/Ecc) shoulder strength (p < 0.05) while internal rotation/ external rotation (IR/ER) ratio can also be a significant predicator on LMSTT >6mm (R2 = 0.462, F = 7.016, df = 1, p = 0.038). Structural change of supraspinatus tendon was not associated with shoulder pain, but could be a predictor on MSTT >6mm in elite swimmers.

A retrospective comparative study of robotic distal pancreatectomy with or without splenic vessel and spleen preservation.

BACKGROUND: Robotic distal pancreatectomy has been accepted to be safe and effective for pancreatic tail lesion. Whether spleen preservation by preserving the splenic vessels with robot assistance is feasible and beneficial remains controversial. Here we would like to compare the operative outcomes of robotic distal pancreatectomy and splenectomy (DPS) with robotic spleen preserving distal pancreatectomy by means of splenic vessel preservation (SVP). METHODS: Between March 2011 and September 2019, 56 consecutive patients undergoing robotic distal pancreatectomy were identified, with 28 patients in each group. Patient demographics, histopathology findings and operative outcomes were prospectively collected and compared between the two groups. A subgroup analysis was made after excluding malignant and pancreatic lesions >6 cm in the DPS group. RESULTS: The two groups had similar conversion rate, blood loss, morbidity and pancreatic fistula rate. There was no operative mortality. The SVP group had shorter median operative time (245 vs 303.5 min, P = 0.019) and shorter median hospital stay (5 vs 6 days, P = 0.019) than the DPS group. However, all malignant lesions occurred in the DPS group and lesion size in DPS group was significantly larger. After matching, there were 28 SVP and 15 DPS. The histopathology findings and lesion size became comparable. The SVP group still had shorter operative time (245 vs 290 min, P = 0.022) and shorter hospital stay (5 vs 7 days, P = 0.014) than the DPS group. CONCLUSION: Apart from avoiding risk of overwhelming postsplenectomy sepsis, robotic SVP had additional advantage of shorter operative time and shorter hospital stay than robotic DPS.

Investigation of Underwater Shoulder Muscle Activity during Manikin-Carrying in Young Elite Lifesaving Athletes.

Manikin carrying is a lifesaving sports technique, in which athletes stroke with one arm and carry a manikin of 60 kg with the other arm as they swim. Stabilizing the manikin exerts great demand on the shoulder muscles of the carrying arm; thus, this study aimed to investigate the muscle activation of the carrying shoulder and the possible factors associated with it. This was a cross-sectional study, in which 20 young elite lifesaving athletes were recruited from the Hong Kong Lifesaving Society. The muscle activity of the posterior deltoid (PD), teres major (TM), and middle trapezius (MT) were recorded with wireless surface electromyography (sEMG) during the performance of 25-m manikin carrying in a swimming pool. The 25-m manikin-carrying was divided into and analyzed in 3 phases: initial, middle, and end phase. The initial phase was defined as the period from the athlete's first swimming stroke to the end of the third stroke; the middle phase was defined as the period between the initial and the end phase; and the end phase was defined as the period from the last third stroke to the last stroke at the 25-m finishing line. The first web space and grip strength were measured. The speed and number of inhalations were calculated. PD showed muscle activity of 55.73% of maximal voluntary isometric contraction (MVIC) in the initial phase and 40.21% MVIC in middle phase. TM showed a muscle activity of 65.26% MVIC in the initial phase and 64.35% MVIC in the middle phase. MT showed 84.54% MVIC in the initial phase and 68.54% MVIC in the middle phase. Young elite athletes showed significant use of PD, TM, and MT during manikin-carrying. The muscle activity levels correlated with the first web space, grip strength, speed, and number of inhalations of the athletes.

Lower-Limb Muscle Activity During Aquatic Treadmill Running in Individuals With Anterior Cruciate Ligament Reconstruction.

INTRODUCTION: While anterior cruciate ligament (ACL) tears are commonly managed with ACL reconstruction (ACL-R), 35% of ACL-R individuals fail to return to the preinjury elite sport level. Persistent neuromuscular deficits in the hamstrings and quadriceps have been observed. It has been proposed that aquatic therapy can be used to optimize neuromuscular control after ACL-R. OBJECTIVES: (1) To compare muscle activity in ACL-R individuals during aquatic treadmill (ATM) running at different water depths and (2) to compare muscle activity during ATM running between ACL-R and healthy individuals. METHODS: A total of 38 participants, including 18 ACL-R individuals (mean postoperative time [SD] = 25.8 [25.0] mo) and 20 healthy individuals were recruited. Muscle activity of biceps femoris (BF), rectus femoris (RF), tibialis anterior, and medial gastrocnemius during land treadmill and ATM running at mid-shin, mid-thigh, and waist levels were recorded using surface electromyography (sEMG).  The sEMG signals of the selected muscles were normalized and expressed in % Maximal Voluntary Contraction (%MVC). Muscle activity of the ACL-R, ACL-contralateral, and healthy control limbs at different water depths was compared. RESULTS: Among the 3 groups, the ACL-R group demonstrated the most prominent percentage increase of 101.97% (P = .001) at mid-shin level, 139.66% (P = .001) at mid-thigh level, and 141.97% (P < .001) at waist level, respectively, in %MVC when compared to land. In the ACL-R group, muscle activity of BF in the stance phase (BFSt) was significantly higher than the control group on land at all water depths. Muscle activity of RF in the swing phase (RFSw) in the ACL-R group significantly increased in all water depths immersion when compared to land, respectively. CONCLUSION: This study showed an increasing trend in muscle activity of BFSt and RFSw in ACL-R individuals during ATM running at increased water depths. ATM running could be implemented as neuromuscular training in rehabilitation after ACL-R.

Robotic versus open hemihepatectomy: a propensity score-matched study.

BACKGROUND: Minimally invasive approach has been increasingly applied in liver resection. However, laparoscopic major hepatectomy is technically demanding and is practiced only in expert centers around the world. Conversely, use of robot may help to overcome the difficulty and facilitate major hepatectomy. METHODS: Between September 2010 and March 2019, 151 patients received robotic hepatectomy for various indications in our center. 36 patients received robotic hemihepatectomy: 26 left hepatectomy and 10 right hepatectomy. During the same period, 737 patients received open hepatectomy and out of these, 173 patients received open hemihepatectomy. A propensity score-matched analysis was performed in a 1:1 ratio. RESULTS: After matching, there were 36 patients each in the robotic and open group. The two groups were comparable in demographic data, type of hemihepatectomy, underlying pathology, size of tumor, and background cirrhosis. Conversion was needed in 3 patients (8.3%) in the robotic group. There was no operative mortality. The operative blood loss and resection margin were similar. Though not significantly different, there was a higher rate of complications in the robotic group (36.1% vs. 22.2%) and this difference was mostly driven by higher intra-abdominal collection (16.7% vs. 5.6%) and bile leak (5.6% vs. 2.8%). Operative time was significantly longer (400.8 ± 136.1 min vs 255.4 ± 74.4 min, P < 0.001) but the postoperative hospital stay was significantly shorter (median 5 days vs 6.5 days, P = 0.040) in the robotic group. When right and left hepatectomy were analyzed separately, the advantage of shorter hospital stay remained in left but not right hepatectomy. For patients with hepatocellular carcinoma, there was no difference between the two groups in 5-year overall and disease-free survival. CONCLUSION: Compared with the open approach, robotic hemihepatectomy has longer operation time but shorter hospital stay. Thus, use of robot is feasible and effective in hemihepatectomy with the benefit of shorter hospital stay.

Development and validation of a novel nomogram predicting 10-year actual survival after curative hepatectomy for hepatocellular carcinoma.

INTRODUCTION: Although hepatectomy is a curative treatment modality for hepatocellular carcinoma (HCC), the associated 10-year long-term actual survival are rarely reported. This study aims to develop and validate a predictive nomogram for 10-year actual survivors with HCC. MATERIALS AND METHODS: From 2004 to 2009, 753 patients with curative hepatectomy for HCC (development set, n = 325; validation set, n = 428) were included. In development set, comparison of clinic-pathological data was made between patients surviving ≥10 years and those surviving <10 years. Good independent prognostic factors identified by multivariate analysis were involved in a nomogram development, which was validated internally and externally using validation set. RESULTS: On multivariate analysis, five independent good prognostic factors for 10-year survival were identified, including young age (OR = 0.943), good ASA status (≤2) (OR = 2.794), higher albumin level (OR = 1.116), solitary tumor (OR = 2.531) and absence of microvascular invasion (OR = 3.367). A novel nomogram was constructed with C-index of 0.801 (95% CI 0.762-0.864). A cut-off point of 167.5 had a sensitivity of 0.794 and specificity of 0.730. Internal validation using bootstrap sampling and external validation using validation set revealed C-index of 0.792 (95% CI, 0.741-0.853) and 0.761 (95% CI, 0.718-0.817). CONCLUSION: A novel nomogram for 10-year HCC survivor using age, ASA status, preoperative albumin, tumor number and presence of microvascular tumor invasion was developed and validated with high accuracy.

A Systematic Review and Meta-Analysis: Biomechanical Evaluation of the Effectiveness of Strength and Conditioning Training Programs on Front Crawl Swimming Performance.

The objectives of this systematic review were to summarize and evaluate the effectiveness of strength and conditioning trainings on front crawl swimming, starts and turns performance with relevant biomechanical parameters. Four online databases including PudMed, ESCSOhost, Web of Science and SPORTDiscus were searched according to different combination of keywords. 954 articles were extracted from databases, and ultimately 15 articles were included in this study after removal of duplicate and articles screening according to inclusion and exclusion criteria. Meta-analyses were adopted when appropriate and Egger's regression symmetry was adopted to assess the publication bias and the results were presented with forest plots and funnel plots respectively. Fifteen articles studied the effects of strength and resistance, core, and plyometric trainings. The quality of the investigation was assessed by the checklist developed by Downs and Black. Most of the investigations found out that training programs were beneficial to front crawl sprinting swimming performance, stroke biomechanics, force, and muscle strength. First, strength and resistance trainings and core trainings were effective on sprinting performance enhancement. Second, resistance trainings were found to have positive effects on stroke rate. Plyometric trainings were beneficial to start performance, while there was no sufficient evidence for confirming the positive improvement on turn biomechanical, also overall swimming performance, after weeks of plyometric trainings. Strength and Conditioning trainings are suggested to implement in regular training regime regarding to the positive effects on swimming performance, including starts, turns and front crawl swim, and relevant biomechanical parameters, instead of swimming training only. Further research with higher quality is recommended to conduct and more investigations on the training effects to other stroke styles are also suggested.

The effect of a low glycaemic index diet on reducing day-long glycaemia in healthy young adults: A randomized crossover trial.

AIM: To compare the effect of a low glycaemic index (LGI) diet on reducing day-long glycaemia with a macronutrient-matched high glycaemic index (HGI) diet, using customized meal delivery to ensure compliance. MATERIALS AND METHODS: We conducted a single-blinded, randomized crossover trial in 14 healthy adults (57% female) with a mean ± SD age of 21.6 ± 1.7 years. A flash glucose monitoring sensor was installed on the subjects on day 1 to capture the interstitial glucose level every 15 minutes for 14 days. Subjects were randomized to receive an LGI (dietary GI = 40) or HGI (dietary GI = 60) diet (three meals and two snacks) from day 2 for 5 consecutive days, followed by a 2-day washout, then switched to the alternative diet for another 5 days. A paired t-test was used to test the differences in the incremental area under the curve (iAUC) of glucose, postprandial glucose (PPG) concentration and maximum postprandial glucose rise (MPGR) between the LGI and HGI periods. RESULTS: Subjects had lower iAUC for average day-long glycaemia during the LGI intervention period compared with the HGI period (mean ± SD, 865 ± 297 vs. 1024 ± 267 mmol x min/L; P = .047). PPG for breakfast and snack 2, and MPGR for breakfast, snack 2 and dinner, were lower in the LGI period. CONCLUSIONS: In young healthy adults, following an LGI diet resulted in lower average day-long glycaemia compared with a macronutrient-matched HGI diet. Our results support the use of LGI diets to reduce the risk of developing glucose intolerance.

Intake of free sugar and micronutrient dilution in Australian children and adolescents.

PURPOSES: This cross-sectional analysis aimed to investigate the association between free sugar intake and micronutrient intake in Australian children and adolescents and to assess the effectiveness of the cut-off of < 10% energy intake from free sugar (%EFS) as recommended by the World Health Organization (WHO). METHODS: Dietary data of children and adolescents from the Australian Health Survey 2011-12 were analyzed (n = 1466). Free sugar intake was estimated using a published methodology with modification to suit the definition of free sugar. Six cut-offs for %EFS were created in 5% increments. Participants' mean intakes of 18 micronutrients, as well as their intakes of core (healthy) and discretionary (unhealthy) foods, at different cut-offs were compared using ANCOVA, with age, sex, and socioeconomic status measures as covariates. The odds ratios of not meeting the nutrient reference values (NRVs) for Australia and New Zealand of each micronutrient were calculated using logistic regression. RESULTS: Micronutrient intake decreased with increasing %EFS and the peak intakes of most micronutrients appeared between 0-15%EFS. The absolute intakes of most micronutrients were not significantly different between participants who consumed < 10%EFS and ≥ 10%EFS. Those with > 20%EFS were less likely to meet the NRVs of more than half of the micronutrients. Additionally, as %EFS increased, intakes of core food groups decreased, while intakes of discretionary food groups increased. CONCLUSIONS: The dilution effect in micronutrient intake with increasing free sugar intake was evident in Australian children and adolescents. However, meeting the WHO cut-off was associated with limited improvement in micronutrient adequacy.

Impact of Intermittent Pringle Maneuver on Long-Term Survival After Hepatectomy for Hepatocellular Carcinoma: Result from Two Combined Randomized Controlled Trials.

BACKGROUND: Hepatectomy remains an important curative treatment for hepatocellular carcinoma (HCC). Intermittent Pringle maneuver (IPM) is commonly applied during hepatectomy for control of bleeding. Whether the ischemia/reperfusion injury brought by IPM adversely affects the operative outcomes is controversial. This study aims to examine whether the application of IPM during hepatectomy affects the long-term outcomes. METHODS: Two randomized controlled trials (RCT) have been carried out previously to evaluate the short-term outcomes of IPM. The present study represented a post hoc analysis on the HCC patients from the first RCT and all patients from the second RCT, and the long-term outcomes were evaluated. RESULTS: There were 88 patients each in the IPM group and the no-Pringle-maneuver (NPM) group. The patient demographics, type and extent of liver resection and histopathological findings were comparable between the two groups. The 1-, 3-, 5-year overall survival in the IPM and NPM groups was 92.0%, 82.0%, 72.1% and 93.2%, 68.8%, 58.1%, respectively (P = 0.030). The 1-, 3-, 5-year disease-free survival in the IPM and NPM groups was 73.6%, 56.2%, 49.7% and 71.6%, 49.4%, 40.3%, respectively (P = 0.366). On multivariable analysis, IPM was a favorable factor for overall survival (P = 0.035). Subgroup analysis showed that a clamp time of 16-30 min (P = 0.024) and cirrhotic patients with IPM (P = 0.009) had better overall survival. CONCLUSION: IPM provided a better overall survival after hepatectomy for patients with HCC. Such survival benefit was noted in cirrhotic patients, and the beneficial duration of clamp was 16-30 min. TRIAL REGISTRATION: NCT00730743 and NCT01759901 ( http://www.clinicaltrials.gov ).

Discrepancy in socioeconomic status does not fully explain the variation in diet quality between consumers of different coffee types.

PURPOSE: Habitual consumers of different coffee types may vary in socioeconomic status (SES), which is an important determinant of diet quality. Nonetheless, research on diet quality among coffee consumers was scarce. We aimed to compare the diet quality of coffee consumers with different preferences towards coffee type and additive usage. METHODS: In this cross-sectional analysis, intake data of food, coffee, and additive usage from the adult respondents of the 2011-2012 Australian Health Survey were used. Participants were grouped according to the type of coffee (espresso and ground coffee, E&G; coffee made from coffee mixes and instant coffee, M&I; non-consumers, NC) and additives (milk, sugar, and intense sweetener) consumed. Adjusted food group intake was compared between consumption groups using general linear model. RESULTS: E&G drinkers had better SES than M&I and NC. After adjusting for covariates, the mean dairy intake of E&G drinkers was 22.2% higher than M&I drinkers (p < 0.001) and 33.1% higher than NC (p < 0.001). Mean discretionary food intake of E&G drinkers was 12.1% lower than M&I (p = 0.003) and 12.3% lower than NC (p = 0.001). In terms of additive usage, non-users of coffee additive had the lowest dairy food intake and the highest discretionary food intake. CONCLUSIONS: Coffee consumers' different preferences towards coffee type and additive usages reflected significant variations in their diet quality, even after adjustment of SES. Therefore, future epidemiological studies should consider separating coffee drinkers according to their habitual consumption of different types of coffee.

Microwave ablation provides better survival than liver resection for hepatocellular carcinoma in patients with borderline liver function: application of ALBI score to patient selection.

BACKGROUND: Studies comparing microwave ablation (MWA) and liver resection are lacking. This study evaluates the survival of patients with hepatocellular carcinoma (HCC) treated with liver resection or MWA and the role of Albumin-Bilirubin (ALBI) score in patient selection for treatments. METHODS: This is a retrospective analysis of patients who received curative liver resection or MWA for HCC. Propensity score matching was used at a 1:1 ratio. The value of ALBI grade for patient selection was evaluated. Overall and disease-free survival were compared between two groups. RESULTS: Of the 442 patients underwent MWA or liver resection for HCC during the study period, 63 patients received MWA and 379 patients received liver resection. Propensity scoring matching analysis resulted in 63 matched pairs for further analysis. Subgroup analysis according to the ALBI grade was performed. Liver resection offered better overall and disease-free survivals in patients with ALBI grade 1. MWA provided a significantly better overall survival (p = 0.025) and a trend towards better disease-free survival (p = 0.39) in patients with ALBI grade 2 or 3. CONCLUSIONS: Liver resection offered superior disease-free survival to MWA in patients with HCC. The ALBI grade could identify patients with worse liver function who might gain survival advantage from MWA.
