Mesoporous hydrogel electrodes with flexible frameworks exhibiting enhanced mass transport for the oxygen evolution reaction.

Mesoporous hydrogel electrodes with unique flexible mesopores surrounded by CoOOH nanosheets were prepared via the electrochemical deposition of hybrid cobalt hydroxide nanosheets, exhibiting high oxygen evolution reaction activity at a high current density owing to the enhanced mass transport of oxygen molecules.

Clinical Features and Outcomes of Conversion Therapy in Patients with Unresectable Hepatocellular Carcinoma.

This retrospective multicenter study analyzed 244 patients with unresectable hepatocellular carcinoma treated with lenvatinib (LEN) and atezolizumab + bevacizumab (Atezo + Bev) to examine the characteristics, treatment courses, and prognoses. The cases of patients who could achieve HCC downstaging from Barcelona Clinic Liver Cancer (BCLC) stage B or C to A or zero indicated the need for conversion therapy. The patients' prognoses with and without conversion therapy were compared. Of the 244 patients, 12 (4.9%) underwent conversion therapy, six out of 131 (4.6%) were treated with LEN, and six out of 113 (5.3%) were treated with Atezo + Bev. Eleven patients (91.7%) with a modified albumin bilirubin (mALBI) grade 1 or 2a and BCLC-B stage showed significantly higher rates of transition during conversion therapy (p < 0.05). The patients undergoing conversion therapy had a significantly longer median overall survival rate than those receiving chemotherapy alone (1208 [1064-NA] vs. 569 [466-704] days, p < 0.01). A comparison of the patients who achieved a partial response with and without conversion was evaluated using propensity score matching to reduce the confounding factors, showing a significant survival benefit in the conversion group (1208 [1064-NA] vs. 665 days, p < 0.01). Among the patients with u-HCC who were treated with LEN and Atezo + Bev, those with mALBI 1 + 2a and BCLC-B were likely to achieve conversion therapy with downstaging.

Evaluation of the activities of the intrinsic and extrinsic muscles of the foot during toe flexion with or without interphalangeal joint flexion using ultrasound shear wave elastography.

The intrinsic muscles of the foot are important to maintain the arch of the foot and to participate in sports activities. Using ultrasound shear wave elastography, we investigated the effect of different toe flexion methods on the activity of the intrinsic and extrinsic muscles of the foot. The study included 15 healthy adults who performed toe flexion under 2 conditions: with interphalangeal (IP) joint flexion and without IP joint flexion. The applied load during flexion was 500 g. Muscle stiffness was measured in the abductor hallucis, flexor hallucis brevis, flexor digitorum brevis, quadratus plantae, flexor hallucis longus, and flexor digitorum longus muscles using ultrasound shear wave elastography. Muscle stiffness was statistically compared with IP flexion and without IP flexion (P < 0.05). The stiffness of the abductor hallucis (P < 0.0005), flexor hallucis brevis (P = 0.022), and flexor digitorum brevis muscles (P < 0.0005) was significantly greater without IP flexion than with IP flexion. In contrast, the muscle stiffness of the flexor hallucis longus (P = 0.001) and the flexor digitorum longus (P = 0.004) was significantly greater during with IP flexion than without IP flexion. This study shows that the abductor hallucis, flexor hallucis brevis, flexor digitorum brevis muscles are more active during toe flexion without IP flexion. These results suggest that the toe flexion method is important for more effective training of the intrinsic muscles of the foot.

Principles of Self-Repairing Ability of Tripodal Ligand-Stabilized Hybrid Cobalt Hydroxide Nanosheets for Alkaline Water Electrolysis.

Self-repairing catalysts are promising new materials for achieving long lifetime of alkaline water electrolyzers powered by renewable energy. Catalytic nanoparticles dispersed in an electrolyte were deposited on the anode to repair a catalyst layer by electrolysis. A hybrid cobalt hydroxide nanosheet modified with tris(hydroxymethyl)aminomethane on the surface (Co-ns) was used as a catalyst. Assuming a pseudo-first-order process, the rate constant of an electrochemical deposition was linearly correlated with the electrode potential during electrolysis. Thus, it is expected that the repair of the catalyst is automatically controlled by changes in the oxygen evolution reaction (OER) overpotential. The essential step of the electrochemical deposition was the anodic oxidation of Co2+ to Co3+ . Surface modification of Co-ns protects Co2+ against the autooxidation of Co2+ caused by the dissolved oxygen. The redox properties and organic modification of Co-ns make them well-suited for the self-repairing of anode catalysts.

Influence of alcohol on newly developed metabolic dysfunction-associated fatty liver disease in both sexes: A longitudinal study.

BACKGROUND & AIMS: The influence of changes in alcohol consumption on newly developed metabolic dysfunction-associated fatty liver disease (MAFLD) is unclear. We investigated the influence of alcohol consumption on newly developed MAFLD in both sexes. METHODS: This observational cohort study included 4071 patients who underwent more than two health check-ups between 2015 and 2020 over an interval of more than a year. Generalised estimating equations were used for analyses. RESULTS: At baseline, the rates of drinking and MAFLD between men and women were 72.5% versus 41.7% and 42.2% versus 22.1%, respectively. At the most recent stage, the rates of an increase in alcohol consumption for men and women were 13.3% and 8.7%, respectively, and 311/1192 (26.1%) men and 155/1566 (9.9%) women had newly developed MAFLD. The odds ratio (OR) for drinking in patients with newly developed MAFLD was 0.863 (men) (95% confidence interval [CI], 0.676-1.102, p = 0.237) and 1.041 (women) (95% CI, 0.753-1.439, p = 0.808); the OR for women who drank 140-279.9 g/week was 2.135 (95% CI, 1.158-3.939, p < 0.05) and that for all drinking categories among women was >1. Several non-invasive fibrosis scores were significantly associated with the quantity of alcohol consumption in patients with newly developed MAFLD (p < 0.005). CONCLUSIONS: Alcohol consumption had no significant protective effect against newly developed MAFLD in both sexes, regardless of quantity. Conversely, alcohol consumption ≥140 g/week was a risk factor for newly developed MAFLD in women. The development of liver fibrosis with increased alcohol intake should be considered in patients with MAFLD.

A case of complete response with rechallenge-lenvatinib plus transcatheter arterial chemoembolization for unresectable hepatocellular carcinoma refractory to multiple molecular-targeted agent treatments.

The efficacy of lenvatinib (LEN) plus transcatheter arterial chemoembolization (LEN-TACE) has been reported, but its effect on unresectable hepatocellular carcinoma (HCC) refractory to LEN therapy has not been demonstrated. We report a case of HCC refractory to multiple molecular-targeted agents (MTA) treatments, including LEN, that was successfully treated with LEN-TACE. A 59-year-old man was referred to our department with multiple HCCs and a background of hepatitis B virus infection. TACE was the initial treatment. However, he was determined to be TACE-refractory, and multitargeted therapy was initiated. LEN was started at 12 mg/day but resulted in progressive disease (PD) after 13 months of the administration. The response to second-line sorafenib was PD after 2 months. Third-line therapy with atezolizumab + bevacizumab was stopped after one course because of an immune-related adverse event (i.e., dermatitis). The response to fourth-line regorafenib was PD at 2 months, and the response to fifth-line cabozantinib was PD after 6 months. The efficacy of LEN-TACE was recently reported; therefore, we decided to attempt LEN-TACE therapy as a salvage line. After obtaining the patient's consent to repeat LEN and TACE, treatment was initiated. The tumor markers levels markedly reduced after LEN-TACE therapy. After three additional TACE treatments with continued LEN administration, the tumor marker levels normalized, and complete response was determined based on RECIST guidelines. LEN-TACE therapy may effectively treat unresectable advanced HCC in the LEN-rechallenge setting and may be a treatment option as a last-line therapeutic option.

Multicenter retrospective study of initial treatment outcome and feasibility of initiating dose reduction of cabozantinib in unresectable hepatocellular carcinoma.

AIM: Cabozantinib (CAB), a multiple kinase inhibitor, has been approved for use in patients with previously treated unresectable hepatocellular carcinoma (uHCC). However, real-world clinical data are lacking, particularly clinical data regarding dose modifications of CAB. We analyzed the clinical outcomes of CAB in uHCC and compared treatment outcomes between the full- and reduced-dose groups. METHODS: This multicenter, observational study included patients with uHCC who were treated with CAB from March 2021 to April 2022. Patient characteristics, efficacy, and safety were compared between the full- and reduced-dose groups. RESULTS: Twenty-six patients from eight institutes were analyzed. Cabozantinib was administered as a third-line or later treatment in 25 (96.2%) patients and postimmunotherapy in 21 (80.5%) patients. There were 15 patients in the full-dose group (60 mg CAB) and 11 in the reduced-dose group (40 or 20 mg CAB). The objective response rate (ORR) and disease control rate (DCR) were not significantly different between the two groups. The ORR was 6.7% for the full-dose group and 9.1% for the reduced-dose group, and the DCR was 53.4% and 81.8%, respectively. Progression-free survival analysis showed no significant differences between the two groups. The incidence of decreased appetite, fatigue, and diarrhea, and the rate of discontinuation and dose reduction, was significantly higher in the full-dose group. CONCLUSIONS: Our study suggests that the efficacy and safety of CAB in real-world clinical practice are comparable to those of the phase III trial (CELESTIAL), and that dose reduction of CAB may be a safer treatment option.

Initial therapeutic results of atezolizumab plus bevacizumab for unresectable advanced hepatocellular carcinoma and the importance of hepatic functional reserve.

AIM: We analyzed the association between the modified albumin-bilirubin (mALBI) grade and therapeutic efficacy of atezolizumab plus bevacizumab (Atezo+Bev) for the treatment of unresectable hepatocellular carcinoma (u-HCC). METHODS: In this retrospective observational study, we included 71 u-HCC patients treated with Atezo+Bev between September 2020 and September 2021. Patients were grouped corresponding to the mALBI grade at the start of treatment (mALBI 1+2a or mALBI 2b+3) and analyzed for therapeutic effect and the transition rate to secondary treatment. RESULTS: According to the Response Evaluation Criteria in Solid Tumors, the overall response rate was significantly higher for the mALBI 1+2a group, than for the mALBI 2b+3 group, with 26.2% and 3.4%, respectively. The progression-free survival (PFS) was significantly longer in the mALBI 1+2a group (10.5 months) than in the mALBI 2b+3 group (3.0 months). In the multivariate analysis, an mALBI of 1+2a was found to be an independent factor of PFS. The rate of second-line treatment with multi-targeted agents was also significantly higher in the mALBI 1+2a group. CONCLUSIONS: In real-world practice, Atezo+Bev treatment might have higher therapeutic efficacy in u-HCC patients with mALBI 1+2a.

Relationships between flexion strength and dexterity of the toes and physical performance.

BACKGROUND: Toe function is characterised by the strength and dexterity of toe motion. However, previous studies have mostly focused on the importance of toe strength. OBJECTIVE: This study aimed to investigate the relationships between flexion strength and dexterity of the toes and physical performance. METHODS: Twenty healthy participants were included in this study. The flexion force of each toe was measured using a digital force gauge, and the toe dexterity was evaluated using the marble pick-up and rock-paper-scissors tests. These parameters were statistically analysed in relation to physical performance, including repeated side step and balance ability, which was evaluated using centre of pressure (COP) data during single-leg standing, tiptoe standing, and single-leg drop-jumping. RESULTS: A significant correlation was found between the first toe flexion force and the total trajectory length of the COP during one-leg standing and between the time required for marble pick-up and the rock-paper-scissors score and the COP during single-leg drop-jumping. CONCLUSION: The results underscore the importance of flexion strength and dexterity of the toes in human physical performance and the necessity for the evaluation and improvement of both functions.

Influence of Alcohol Consumption on the Development of Erosive Esophagitis in Both Sexes: A Longitudinal Study.

The influence of changes in alcohol consumption on erosive esophagitis (EE) development in both sexes is unclear. This observational study investigated sex differences in the influence of alcohol consumption on EE development, and included 2582 patients without EE at baseline from 13,448 patients who underwent >2 health check-ups over >1 year. The rates of non-drinkers who started drinking, and drinkers who abstained from drinking, who increased, and who decreased their weekly alcohol consumption were 7.2%, 9.7%, 14.7%, and 24.1% and 7.3%, 17.8%, 12.8%, and 39.0% in men and women, respectively. In the final cohort, 211/1405 (15.0%) men and 79/1177 (6.7%) women newly developed EE. The odds ratio (OR) for drinking in EE development was 1.252 (95% confidence interval (CI), 0.907−1.726) among men and 1.078 (95% CI, 0.666−1.747) among women. Among men aged <50 years, the OR for drinking ≥70 g/week in EE development was 2.825 (95% CI, 1.427−5.592), whereas among women, the OR for drinking ≥140 g/week in EE development was 3.248 (95% CI, 1.646−6.410). Among participants aged <50 years, the OR for daily drinking in EE development was 2.692 (95% CI, 1.298−5.586) among men and 4.030 (95% CI, 1.404−11.57) among women. The influence of alcohol consumption on EE development differed between the sexes. We recommend no alcohol consumption for individuals aged <50 years to avoid EE development. Daily drinkers should be assessed for EE development.

Comparison of the role of alcohol consumption and qualitative abdominal fat on NAFLD and MAFLD in males and females.

The clinical difference between nonalcoholic fatty liver disease (NAFLD) and metabolic-associated fatty liver disease (MAFLD) between the two sexes is unclear. This study aimed to determine the influences of alcohol consumption and qualitative abdominal fat between male and female patients with NAFLD and MAFLD. This cross-sectional study examined 11,766 participants who underwent health check-ups comparing lifestyle habits, biochemical features, and noninvasive liver fibrosis scores, between non-MAFLD and MAFLD groups. Furthermore, differences in alcohol consumption and qualitative abdominal fat were examined between male and female patients with NAFLD and MAFLD. The prevalence of metabolic dysregulation, ratio of visceral fat area to subcutaneous fat area, and noninvasive liver fibrosis scores were significantly higher in male patients with MAFLD than in those with NAFLD (p < 0.05), but these were not significantly different in female patients. Among male patients with an alcohol consumption of > 70 g/week, several noninvasive liver fibrosis scores were significantly higher in the MAFLD group than in the NAFLD group (all p < 0.05). The influences of alcohol consumption and qualitative abdominal fat on NAFLD and MAFLD were different between sexes. The development of liver fibrosis should be considered in male patients with MAFLD who exceed mild drinking.

Long-Term Survival due to Chemotherapy including Paclitaxel in a Patient with Metastatic Primary Splenic Angiosarcoma.

A primary splenic angiosarcoma is a rare type of soft tissue sarcoma and is associated with an extremely poor prognosis. In this study, we describe the case of a patient who was diagnosed with metastatic primary splenic angiosarcoma and survived for about 2 years. A 62-year-old female was referred to us for the treatment of splenic angiosarcoma with disseminated intravascular coagulation (DIC) and multiple liver and bone metastases. Paclitaxel therapy resulted in recovery from DIC and enabled her to continue sequential treatment through to sixth-line chemotherapy. We reviewed all splenic angiosarcoma case reports which were described as stage IV to date and compared with our case. From these data, we found that the median overall survival was 105 days, and the prognosis of splenic angiosarcoma of stage IV was worse than conventional case series. Splenectomy was performed in more patients than chemotherapy as a treatment. Moreover, various chemotherapeutic regimens were used. These data suggest that administering chemotherapy including paclitaxel to patients with splenic angiosarcoma might improve their prognosis.

Therapeutic efficacy of lenvatinib in nonviral unresectable hepatocellular carcinoma.

AIM: To investigate the therapeutic effect of lenvatinib (LEN) in liver disease etiology, especially nonviral hepatocellular carcinoma (HCC). METHODS AND RESULTS: Sixty-seven patients with unresectable advanced HCC (u-HCC) treated with LEN and consisting of 26 hepatitis C virus (HCV), 19 hepatitis B virus (HBV), 11 alcohol, and 11 nonalcoholic steatohepatitis (NASH) cases were retrospectively recruited. Univariate and multivariate Cox proportional hazard models were used to determine predictive factors for survival. The objective response rate in the nonviral (alcohol and NASH) group was higher than that in the viral group (59.1% [13/22] vs. 46.7% [21/45]). Progression-free survival was significantly longer in the nonviral group than in the viral group (13.7 vs. 6.6 months; hazard ratio [HR] 0.324; 95% confidence interval [CI] 0.174-0.602; P < 0.01). Similarly, median overall survival (OS) was significantly longer in the nonviral group than in the viral group (not evaluable vs. 15.9 months; HR = 0.277; 95% CI = 0.116-0.662; P < 0.01). Multivariate analysis revealed that portal vein invasion (HR = 5.327, P = 0.0025), treatment line (HR = 0.455, P = 0.023), and etiology (HR = 0.180, P = 0.00055) were significant independent factors associated with OS in u-HCC patients treated with LEN. CONCLUSION: Our results suggest that LEN is more effective against nonviral u-HCC than against viral u-HCC.

MiR-125b-5p Is Involved in Sorafenib Resistance through Ataxin-1-Mediated Epithelial-Mesenchymal Transition in Hepatocellular Carcinoma.

The mechanism of resistance to sorafenib in hepatocellular carcinoma (HCC) remains unclear. We analyzed miRNA expression profiles in sorafenib-resistant HCC cell lines (PLC/PRF5-R1/R2) and parental cell lines (PLC/PRF5) to identify the miRNAs responsible for resistance. Drug sensitivity, migration/invasion capabilities, and epithelial-mesenchymal transition (EMT) properties were analyzed by biochemical methods. The clinical relevance of the target genes to survival in HCC patients were assessed using a public database. Four miRNAs were significantly upregulated in PLC/PRF5-R1/-R2 compared with PLC/PRF5. Among them, miR-125b-5p mimic-transfected PLC/PRF5 cells (PLC/PRF5-miR125b) and showed a significantly higher IC50 for sorafenib compared with controls, while the other miRNA mimics did not. PLC/PRF5-miR125b showed lower E-cadherin and higher Snail and vimentin expression-findings similar to those for PLC/PRF5-R2-which suggests the induction of EMT in those cells. PLC/PRF5-miR125b exhibited significantly higher migration and invasion capabilities and induced sorafenib resistance in an in vivo mouse model. Bioinformatic analysis revealed ataxin-1 as a target gene of miR-125b-5p. PLC/PRF5 cells transfected with ataxin-1 siRNA showed a significantly higher IC50, higher migration/invasion capability, higher cancer stem cell population, and an EMT phenotype. Median overall survival in the low-ataxin-1 patient group was significantly shorter than in the high-ataxin-1 group. In conclusion, miR-125b-5p suppressed ataxin-1 and consequently induced Snail-mediated EMT and stemness, leading to a poor prognosis in HCC patients.

Sequential therapy including regorafenib for unresectable hepatocellular carcinoma: Effect of early relative changes in hepatic functional reserve after regorafenib administration on prognosis.

AIM: Regorafenib is a second-line treatment for unresectable hepatocellular carcinoma after sorafenib-refractory treatment. This study examined the effects of regorafenib administration on hepatic functional reserve and the treatment course after regorafenib discontinuation. METHODS: This retrospective, multicenter study involved 51 patients treated with regorafenib after sorafenib-refractory treatment for u-HCC at seven institutions before March 2021. RESULTS: Fourteen, 13, and 24 patients were classified based on modified albumin-bilirubin (mALBI) grade 1, 2a, and 2b, respectively. The median survival time and progression-free survival were 16.7 and 3.3 months, respectively. Only mALBI grade 2b or 3 was significantly associated with survival rate (hazard ratio, 2.13; 95% confidence interval, 1.01-4.49; p = 0.047). A comparison of median ALBI scores at the initiation of regorafenib (-2.35) with those at 4 weeks (-1.93) revealed a significant relative change (p = 0.0001). After 4 weeks, grade 1 or 2a persisted in 15 patients (Group 1); grade 1 or 2a deteriorated to 2b in 12 patients (Group 2); grade 2b or 3 before regorafenib administration was present in 22 patients (Group 3); and MST was 33.3, 12.8, and 11.3 months in the three groups, respectively (p = 0.05). Patients treated with lenvatinib (LEN) (n = 27, MST = 23.4 months) after regorafenib had a significantly longer survival time from regorafenib initiation than those not treated with LEN (n = 24, 11.8 months; p = 0.043). CONCLUSIONS: Hepatic functional reserve significantly declined after regorafenib administration. During regorafenib treatment, favorable hepatic functional reserve before administration and maintenance of favorable hepatic reserve after administration lead to prolonged prognosis.

Differences in Several Factors in the Development of Erosive Esophagitis Among Patients at Various Stages of Metabolic Syndrome: A Cross-Sectional Study.

BACKGROUND: Erosive esophagitis (EE) is strongly associated with metabolic syndrome (MS), but is not always recognized in individuals with MS and the prevalence of EE in individuals with non-MS is not low. AIM: To examine the differences in clinical factors associated with EE at various stages of MS, as well as the differences in metabolites between subjects with MS, with and without EE. METHODS: A total of 7,097 persons who underwent health checkups including esophagogastroduodenoscopy were analyzed. We examined the differences in clinical factors for EE among subjects with non-MS, pre-MS, and MS and compared metabolites between 34 subjects with MS, with and without EE. RESULTS: EE prevalence was significantly higher in the MS and pre-MS groups than in the non-MS group (p < 0.001). EE severity was higher in the MS group than in the pre-MS and non-MS groups (p < 0.001). In the non-MS group, there were significant differences between subjects with and without EE with respect to Helicobacter pylori (H. pylori) and smoking. In the pre-MS and MS groups, there were significant differences in H. pylori, hiatal hernia, and drinking in those with and without EE. The levels of glutamine, hypoxanthine, and lactic acid metabolites were significantly different between subjects with MS, with and without EE (all p < 0.05). CONCLUSION: Although H. pylori and lifestyle factors such as smoking and drinking are important for EE, differences in these factors should be considered at various stages of MS. Additionally, several metabolites may be involved in the development of EE in MS.

An Adult Case of Congenital Extrahepatic Portosystemic Shunt Successfully Treated with Balloon-occluded Retrograde Transvenous Obliteration.

A 42-year-old woman visited our hospital due to syncope. Contrast-enhanced CT revealed portosystemic shunt, portal vein hypoplasia, and multiple liver nodules. The histological examination of a liver biopsy specimen exhibited portal vein hypoplasia and revealed that the liver tumor was positive for glutamine synthetase. The patient was therefore diagnosed with congenital extrahepatic portosystemic shunt type II, and with focal nodular hyperplasia (FNH)-like nodules. She had the complication of severe portopulmonary hypertension and underwent complete shunt closure by balloon-occluded retrograde transvenous obliteration (B-RTO). The intrahepatic portal vein was well developed at 1 year after B-RTO, and multiple liver nodules completely regressed. Her pulmonary hypertension also improved.

Effective stretching positions for the posterior shoulder capsule as determined by shear wave elastography.

BACKGROUND: Stretching is often used to prevent and treat posterior shoulder capsule tightness; however, the most effective stretching positions are not clearly defined. The purpose of this study was to identify the stretching positions that specifically applied the greatest passive tension on the posterior shoulder capsule by evaluating the elastic characteristics of posterior capsules and muscles in various stretching positions using ultrasound shear wave elastography (SWE). METHODS: We evaluated 9 fresh-frozen shoulders (mean age 86.6 ± 7.7 years) without osteoarthritis or rotator cuff tears. All posterior shoulder tissues were preserved intact. Shear moduli of the middle and inferior posterior shoulder capsules and the posterior shoulder muscles were evaluated using SWE. We obtained shear modulus measurements in 9 stretching positions using a combination of glenohumeral elevation planes and angles (frontal, sagittal, scapular; -30°, 0°, 30°, 60°, respectively). A 4-Nm torque for shoulder internal rotation or horizontal adduction was applied in each position. We also measured shear moduli in the resting position (0° elevation with neutral shoulder internal/external rotation). We compared the shear moduli of all stretching and resting positions using 1-way repeated measures analysis of variance (P < .05). In addition, we compared the shear modulus in 2 positions (ie, resting and each stretching) among tissues (ie, capsules and muscles) with repeated measures using 2-way analysis of variance (P < .05). RESULTS: Shear modulus values for the middle posterior capsules in "internal rotation at 30° in scapular plane elevation" (28.7 ± 14.3 kPa, P = .01) and in "horizontal adduction at 60° of elevation" (31.1 ± 13.1 kPa, P < .001) were significantly higher than that of the resting position (11.0 ± 7.3 kPa). The shear modulus value for the inferior posterior capsule in "internal rotation at 30° of flexion" was significantly higher than that of the resting position (39.0 ± 17.3 vs. 15.4 ± 13.9 kPa, respectively; P = .004). Additionally, the shear modulus values for the posterior capsules in "internal rotation at 30° in scapular plane elevation and flexion" were significantly higher than that of the posterior shoulder muscles. CONCLUSION: Effective middle posterior shoulder capsule stretching positions were shoulder "internal rotation at 30° of scapular plane elevation" and "horizontal adduction at 60° of elevation." Shoulder "internal rotation at 30° of flexion" was the most effective position for the inferior posterior shoulder capsule. Stretching in these positions could relieve posterior shoulder capsule tightness and contribute to the prevention and treatment of throwing injuries of the shoulder.

Comparison of therapeutic outcomes of sorafenib and lenvatinib as primary treatments for hepatocellular carcinoma with a focus on molecular-targeted agent sequential therapy: A propensity score-matched analysis.

AIM: The optimal choice between sorafenib (SOR) or lenvatinib (LEN) as the first-line treatment for unresectable hepatocellular carcinoma (u-HCC) remains debatable. Using propensity score matching, this study compares the outcomes of SOR and LEN in the molecular-targeted agent (MTA) sequential treatment of u-HCC patients. METHODS: This retrospective, multicenter, observational study recruited 137 u-HCC patients who underwent primary treatment with LEN (n = 52) or SOR (n = 85) between June 2017 and June 2020 after regorafenib was approved as the secondary treatment for u-HCC. Propensity score matching was used to reduce confounding, resulting in the selection of 104 patients (n = 52 for the SOR and LEN cohorts). RESULTS: The median overall survival was 21.8 months for LEN and 20.4 months for SOR. LEN exhibited significantly greater therapeutic efficacy as compared to SOR (objective response rate: 3.8% [SOR] vs. 42.3% [LEN], p < 0.01; progression-free survival: 10 months [LEN] vs. 5.1 months [SOR], p < 0.01). No significant intergroup differences were noted in the rate of transition to secondary MTA treatments (SOR: 58.7%; LEN: 48.4%), adverse events (SOR: 86%; LEN: 95%), and maintenance of the Child-Pugh (CP) score during treatment. Compared to non-MTA treatments, secondary MTA treatment achieved a greater improvement in survival (4.3  vs. 2.8 months, p = 0.0047). Multivariate analysis demonstrated that the CP score (p < 0.01) and alpha-fetoprotein level (p < 0.01) were independent prognostic factors. CONCLUSIONS: Both SOR and LEN treatments showed a clinically comparable therapeutic efficacy as the first-line treatments for u-HCC patients in an MTA sequential therapy.

Sorafenib as second-line treatment option after failure of lenvatinib in patients with unresectable hepatocellular carcinoma.

BACKGROUND AND AIM: Currently, there is no molecular-targeted agent that has demonstrated evidence of efficacy in patients with unresectable hepatocellular carcinoma (u-HCC) who have developed resistance to treatment with lenvatinib (LEN). In this real-world study, we aimed to investigate the therapeutic effect and safety of sorafenib (SOR) in patients with u-HCC after progression on treatment with LEN. METHODS PATIENTS AND RESULTS: A total of 13 patients with u-HCC (12 males and 1 female), who were treated with SOR after progression on LEN, were enrolled in this retrospective study. Therapeutic efficacy was evaluated via contrast-enhanced computerized tomography at 8 weeks after the initiation of SOR therapy according to modified response evaluation criteria in solid tumors (mRECIST) and RECIST. According to mRECIST, the objective response rate (ORR) and disease control rate (DCR) were 15.3% (2/13) and 69.2% (9/13), respectively. According to RECIST, the ORR and DCR were 0% (0/13) and 69.2% (9/13), respectively. The median progression-free survival was 4.1 months. The median albumin-bilirubin scores did not deteriorate significantly at 4, 6, and 8 weeks after initiation of SOR, compared with the scores at the baseline. The most frequent grade 1 or 2 adverse events (AEs) were palmar-plantar erythrodysesthesia, fatigue, diarrhea, and hypertension. There was no incidence of grade 3 AEs. CONCLUSION: Treatment with SOR may be effective for u-HCC after failure on LEN and may not worsen the liver reserve.
