The influence of vehicle size on perception and behavior toward drivers.

This study examines the effects of vehicle size on driver impressions and behavioral intentions. Study 1 tested whether vehicle size (large vs. small) affects perceived physical size (height, body shape) through socioeconomic status (SES). We found that large (vs. small) vehicle drivers were perceived as tall (vs. short), and this perception was mediated by the drivers' estimated SES (but not by body shape). Study 2 focused on aggressive behavioral intentions (e.g. honking) toward other drivers, examining whether the relationship between vehicle size and intention was serially mediated by estimated physical size and traits (aggression, power). Here, large (vs. small) vehicle driver were perceived as tall (heavy) and possessing high power (high aggression), which is related to less (more) aggressive behavioral intention toward the driver. Our study suggests that individuals perceive other drivers' physical sizes differently, and this perception is associated with differences in behavioral responses toward other drivers.

Effect of Erector Spinae Plane Block on Postoperative Quality of Recovery in Patients Undergoing Transforaminal or Oblique Lumbar Interbody Fusion: A Randomized Controlled Trial.

BACKGROUND: Erector spinae plane block (ESPB) can has been used for analgesia after lumbar spine surgery. However, its effect on postoperative quality of recovery (QoR) remains underexplored in patients undergoing transforaminal lumbar interbody fusion (TLIF) or oblique lumbar interbody fusion (OLIF). This study hypothesized that ESPB would improve postoperative QoR in this patient cohort. METHODS: Patients undergoing TLIF or OLIF were randomized into ESPB (n=38) and control groups (n=38). In the ESPB group, 25 mL of 0.375% bupivacaine was injected into each erector spinae plane at the T12 level under ultrasound guidance before skin incision. Multimodal analgesia, including wound infiltration, was applied in both groups. The QoR-15 score was measured before surgery and 1 day (primary outcome) and 3 days after surgery. Postoperative pain at rest and during ambulation and postoperative ambulation were also evaluated for 3 days after surgery. RESULTS: Perioperative QoR-15 scores were not significantly different between the ESPB and control groups including at 1 day after surgery (80±28 vs. 81±25, respectively; P=0.897). Patients in the ESPB group had a significantly lower mean (±SD) pain score during ambulation 1 hour after surgery (7±3 vs. 9±1, respectively; P=0.013) and significantly shorter median (interquartile range) time to the first ambulation after surgery (2.0 [1.0 to 5.5] h vs. 5.0 [1.8 to 10.0] h, respectively; P=0.038). There were no between-group differences in pain scores at other times or in the cumulative number of postoperative ambulations. CONCLUSION: ESPB, as performed in this study, did not improve the QoR after TLIF or OLIF with multimodal analgesia.

Pharmacopuncture therapy for adhesive capsulitis: A pragmatic randomized controlled pilot study.

Background: Although several studies have reported the effectiveness of acupuncture treatment for adhesive capsulitis (AC), research on pharmacopuncture therapy for AC remains limited. We compared the effectiveness and safety of pharmacopuncture and physiotherapy for AC. Methods: This pragmatic, randomized, controlled, parallel-group pilot study enrolled patients with limitations of shoulder movement and a numeric rating scale (NRS) score for shoulder pain ≥5 randomized (1:1) to the pharmacopuncture therapy (PPT) and physiotherapy (PT) groups. Treatment sessions were administered twice weekly for 6 weeks, and the participants were followed up for 13 weeks after randomization. The primary outcome was the NRS score for shoulder pain, and the secondary outcomes were the visual analog scale (VAS), Shoulder Pain and Disability Index (SPADI), range of motion (ROM), patient global impression of change (PGIC), EuroQol 5-Dimension 5-Level (EQ-5D-5L), and Short Form 12 Health Survey (SF-12) scores. The intention-to-treat (ITT) analysis was set as the primary analysis. Results: Among 50 participants, for the primary endpoint (week 7) the PPT group showed a significantly superior improvement in NRS, VAS, SPADI, ROM for flexion, ROM for abduction, and EQ-5D-5L scores. The ROM for extension, ROM for adduction, physical component summary, and patient global impression of change were significantly better in the PPT than in the PT group, and these effects were sustained until week 13. Conclusion: In this pilot study, PPT showed better effects than PT, confirming the feasibility of a follow-up main study. Trial registration: Clinicaltrials.gov (NCT05292482) and cris.nih.go.kr (KCT0007198).

Real-time detection of Tau-381 protein using liquid crystal-based sensors for Alzheimer's disease diagnosis.

Tau is a protein found in the central nervous system (CNS) and is involved in stabilizing microtubules in axons. Given the link between Tau levels in the body and Alzheimer's disease (AD), there is a demand for straightforward and precise strategies to detect Tau in body fluids. In this study, we report liquid crystal (LC)-based sensors for the real-time detection of Tau protein, a well-known AD biomarker. The sensor uses a detection method based on the orientation change of the LC because of the competitive biomolecular interaction between Tau and Tau aptamers with the cationic polymer poly-L-lysine (PLL). Tau and its aptamers form stable complexes through electrostatic interactions. Owing to the consumption of the aptamer, the positively charged PLL fails to interact with the aptamer but binds to the negatively charged 1.2-dioleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) sodium salt (DOPG). The PLL and DOPG complex alters the orientation of the LC to ensure a planar anchoring of the 4-cyano-4'-pentylbiphenyl (5CB)/aqueous interface; this anchoring intensifies with increasing Tau concentration, thus enabling the observation of a bright optical image. Our LC-based sensor demonstrated a low detection limit of 2.77 pg/mL in phosphate buffered saline (PBS) and 10.86 pg/mL and 19.31 pg/mL in human serum and plasma, respectively. Moreover, it is anticipated to be suitable for point-of-care diagnosis of AD because it does not require specialized analytical equipment and only requires microliters of sample.

Recurrent Spinal Canal Stenosis after Decompression and Fusion Surgery Due to Bone Overgrowth: Case Report.

Bone regrowth commonly occurs following lumbar decompression surgery. Although it is rare for neurological symptoms to occur due to bone regrowth, this study describes two patients who underwent both decompression and fusion surgeries but experienced spinal canal restenosisthat was severe enough to induce neurological symptoms. A 32-year-old man underwent posterior decompression and posterior lumbar interbody fusion for lumbar canal stenosis at the L4/L5 level 5 years prior. However, the sudden onset of lower back pain occurred 5 years later. Bone overgrowth on the left side was observed at the L4/L5 level. A second surgery was performed, and the patient's symptoms improved significantly. In the second case, a 56-year-old man underwent posterior decompression and posterior lumbar fusion at the L3/L4 and L4/L5 levels for an L4 burst fracture. One month later, he complained of lower back pain and underwent a second posterior decompression surgery. One year later, he presented to an outpatient clinic with lower back pain and neurological symptoms. Bone overgrowth was observed on both sides at the L4/L5 level. Thus, screw removal and laminectomy at the L3, L4, and L5 levels were performed as a third surgery. This study discusses the factors affecting bone regrowth and the methods that can be used to prevent it.

Comparative Study on Hepatoprotective Effects of Traditional Herbs, Roots of Angelica gigas Nakai, Glycyrrhiza uralensis Fischer, Zizyphus jujuba Mill., and Fruits of Paeonia lactiflora Pall., on Ethanol-Induced Liver Injury in Mice.

Alcohol-associated liver disease (ALD) is a major cause of chronic liver disease, with few effective treatments besides alcohol abstinence. Angelicae Gigantis Radix (AG), Glycyrrhizae Radix et Rhizoma (GR), Paeoniae Radix (PR), and Zizyphi Fructus (ZF) are traditional herbs used to treat various ailments, including liver diseases. While several studies have reported the beneficial effects of GR on ALD, the effects of AG, PR, and ZF remain underexplored. Therefore, their efficacy and mechanisms against ALD were investigated using an alcohol-related liver injury model. The model was induced by ethanol gavage in C57BL/6J mice for 14 days, followed by oral administration of AG, GR, PR, and ZF one hour post-induction. The administration of these herbs reduced liver weight, and improved serum biomarkers of liver injury (ALT, AST, albumin). The herbs enhanced hepatic antioxidant capacity (GSH, SOD, catalase) and suppressed the production of proinflammatory cytokines (TNF-α, IL-1ß) and apoptotic changes (caspase-3). The mechanisms of action involved lipid-lowering gene modulation through regulation of the cytochrome P450 2E1/Sirtuin 1/Nrf2 pathways. Histopathological and immunohistochemical analyses revealed that these herbs attenuated hepatocyte damage and steatosis via antioxidant, anti-inflammatory, and antiapoptotic effects. These findings suggest that traditional herbs, particularly AG, could be promising alternative therapies for treating ALD.

Incorporation of Whole-Body Metabolic Tumor Burden into Current Prognostic Models for Non-Small Cell Lung Cancer patients with Spine metastasis.

BACKGROUND CONTEXT: Numerous prognostic models are utilized for surgical decision and prognostication in metastatic spine tumors. However, these models often fail to consider the whole-body tumor burden into account, which may be crucial for the prognosis of metastatic cancers. A potential surrogate marker for tumor burden, whole-body metabolic tumor burden (wMTB), can be calculated from total lesion glycolysis (TLG) obtained from 18F-Fludeoxyglucose positive emission tomography (18F-FDG PET) images. PURPOSE: We aimed to improve prognostic power of current models by incorporating wMTB for non-small cell lung cancer (NSCLC) patients with spine metastases. DESIGN: Retrospective analysis using a review of electrical medical records and survival data. PATIENT SAMPLE: In this study, we included 74 NSCLC patients with image proven spine metastases. OUTCOME MEASURES: Increase in Integrated Discrimination Improvement (IDI) index after incorporation of wMTB into prognostic scores. METHODS: Enrolled patients' baseline data, cancer characteristics and survival status were retrospectively collected. Five widely used prognostic scores (Tomita, Katagiri, Tokuhashi, Global Spine Tumor Study Group [GSTSG], New England Spine Metastasis Score [NESMS]), and TLG indexes were calculated for all patients. The relationships among survival time, prognostic models and TLG values were analyzed. Improvement of prognostic power was validated by incorporating significant TLG index into significant current models. RESULTS: Among current prognostic models, Tomita (EGFR wild-type), Katagiri, GSTSG and Tokuhashi were significantly related to patient survival. Among TLG indexes, LogTLG3 was significantly related to survival. Incorporation of LogTLG3 into significant prognostic models resulted in positive IDI index until three years in all models. CONCLUSION: This study showed that incorporation of wMTB improved prognostic power of current prognostic models of metastatic spine tumors.

Efficacy of Postoperative Oral Nutritional Supplements in Geriatric Hip Fracture Patients Undergoing Total Hip Arthroplasty.

Background/Objectives: Geriatric hip fracture patients have an increased risk of malnutrition. Proper nutritional supply in the perioperative period is very important for their recovery. Oral nutritional supplements (ONSs) are recommended in geriatric hip fracture patients to improve dietary intake and prevent complications. This study aimed to evaluate the efficacy of postoperative ONSs after total hip arthroplasty in geriatric hip fracture patients. Methods: A retrospective study of elderly patients who underwent total hip arthroplasty for hip fracture was conducted. Data from patients who received ONSs postoperatively until hospital discharge (ONS group, n = 69) were compared with patients who did not receive ONSs (control group, n = 168). Laboratory test results, including serum protein and albumin levels, length of hospital stay, and the incidence of postoperative medical complications of the two groups, were analyzed. Results: Preoperative serum protein and albumin levels were significantly higher in the control group (p = 0.002 and p = 0.010, respectively). However, the degree of decline for both protein and albumin levels was significantly less in the ONS group (p < 0.001 for both). Serum albumin levels were significantly higher in the ONS group at postoperative two-week follow-up (p = 0.006). The length of hospital stay was shorter in the ONS group (p < 0.001). The incidence of postoperative delirium was significantly higher in the control group (p = 0.007). Conclusions: In geriatric hip fracture patients, postoperative ONSs can improve postoperative nutritional status, shorten the length of hospital stay, and reduce the incidence of postoperative delirium.

Comparison of Pain and Complications between Outpatients and Inpatients Treated with Bone Marrow Aspirate Concentrate for Knee Osteoarthritis.

Bone marrow aspirate concentrate (BMAC) has been increasingly used as an injectable treatment for knee osteoarthritis (OA). However, there remains a lack of studies on the pain and complications associated with BMAC treatment. This study compared the pain and complications of BMAC treatment between outpatients and inpatients with Kellgren-Lawrence grade II-III knee osteoarthritis (OA) during a follow-up period of ≥3 months. This study included 40 outpatients (40 knees) and 80 inpatients (80 knees) as controls who received BMAC articular injections for knee OA between December 2023 and March 2024. Outpatients were administered BMAC under local anesthesia alone, whereas inpatients were administered BMAC under local anesthesia and intravenous anesthesia. The outcomes were the visual analog scale (VAS) pain score during the BMAC procedure and the complications associated with harvest and injection sites. The mean VAS pain score in the outpatient group was significantly higher than that in the inpatient group during trocar insertion (5.2 vs. 1.3, p < 0.05) and bone marrow aspiration (6.2 vs. 1.4, p < 0.05), but it was similar between the two groups during BMAC injection (2.2 vs. 2.3, p = 0.858). Transient post-treatment complications were observed in 17.5% (7/40) of outpatients and 16.3% (13/80) of inpatients. No significant differences were observed in complications between the two groups, all of which were resolved within 2 months without any specific problem. Moreover, no major complications occurred in any group. In conclusion, outpatients who received only local anesthesia reported significant pain during BMAC treatment. The addition of intravenous anesthesia is necessary to alleviate pain during the BMAC procedure.

Surgical Technique for Complementing Robotic-Assisted Total Knee Arthroplasty in Middle-Aged Patients with Rigid Knee Bones.

This study reports 12 cases of inaccurate bone cutting from a single-surgeon series of 509 consecutively performed robotic-assisted total knee arthroplasty (TKA) for 1 year. In addition, a complementary technique with the combined benefits of robotic-assisted and manual techniques that address this issue is described. From June 2020 to May 2021, a consecutive series of 509 TKAs was performed on 338 patients using a posterior-stabilized total knee prosthesis with a robotic-assisted system at our hospital. The surgical records were reviewed to identify the causative bone locations and bone re-cutting events correlated with improper trial instrument positioning. The re-cutting rate was 2.4% (12/509). All re-cutting attempts occurred because of improper cutting of the femoral posterior chamfer. Re-cutting was attempted mostly on middle-aged male patients. This complementary technique can facilitate manual bone cutting while retaining the advantages of robotic surgery during robotic-assisted TKA. Additionally, the combined technique of manual bone cutting and robotic-assisted surgery can be a useful alternative for middle-aged male patients with rigid knee bones.

Intracorporeal anastomosis in minimally invasive right hemicolectomy: a nationwide survey of the Korean Society of Coloproctology.

Purpose: We investigated the current practices and perceptions of colorectal surgeons in South Korea regarding intracorporeal ileocolic anastomosis (IIA) in minimally invasive right hemicolectomy (RHC). Methods: Members of the Korean Society of Coloproctology (KSCP) participated in an online survey encompassing demographic information, surgical experiences, methods for IIA, and advantages, barriers, and perceptions of IIA. We performed a statistical analysis of survey results. Results: Among the 1,074 KSCP members contacted, 178 responded to the survey. Most respondents were males aged 40-49 years with >10 years of experience who were affiliated with a tertiary healthcare facility. One hundred fifty-six respondents had performed <100 colorectal cancer surgeries annually. Fifty-nine respondents reported experiences of the IIA technique in minimally invasive RHC. Most respondents favored the isoperistaltic side-to-side (S-S) anastomosis and stapled S-S anastomosis, hand-sewn closure for the common channel, and the periumbilical area for primary specimen extraction. Respondents with IIA experience emphasized the reduction in postoperative complications as the primary reason for performing IIA, whereas respondents without IIA experience cited the lack of benefits as the main deterrent. Respondents commonly cited concerns regarding anastomotic leakage and intraabdominal contamination as the primary reasons for not performing IIA. Respondents with IIA experience demonstrated a more positive response towards attempting or transitioning to IIA than those without. Respondents with IIA experience prioritized self-sufficiency, whereas respondents without IIA experience prioritized proctorship and discussions of the initial cases. Conclusion: Measures to standardize the IIA technique and appropriate training programs must be implemented to enhance its use in minimally invasive RHC.

Comparative analysis of organ preservation attempt and radical surgery in clinical T2N0 mid to low rectal cancer.

PURPOSE: Debate persists regarding the feasibility of adopting an organ-preserving strategy as the treatment modality for clinical T2N0 rectal cancer. This study aimed to compare the outcomes of attempting organ-preserving strategies versus radical surgery in patients with clinical T2N0 mid to low rectal cancer. METHODS: Patients diagnosed with clinical T2N0 rectal cancer, with lesions located within 8 cm from the anal verge as determined by pre-treatment magnetic resonance imaging between January 2010 and December 2020 were included. RESULTS: Of 119 patients, 91 and 28 were categorized into the organ-preserving attempt group and the radical surgery group, respectively. The median follow-up duration was 48.8 months (range, 0-134 months). The organ-preserving attempt group exhibited a reduced incidence of stoma formation (44.0% vs. 75.0%; p = 0.004) and a lower occurrence of grade 3 or higher surgical complications (5.8% vs. 21.4%; p = 0.025). Univariate analyses revealed no significant association between treatment strategy and 3-year local recurrence-free survival (organ-preserving attempt 87.9% vs. radical surgery 96.2%; p = 0.129), or 3-year disease-free survival (79.6% vs. 84.9%; p = 0.429). Multivariate analysis did not identify any independent prognostic factors associated with oncologic outcomes. CONCLUSION: Compared with radical surgery, attempted organ preservation resulted in lower incidences of stoma formation and severe surgical complications, whereas oncological outcomes were comparable. Attempting organ preservation may be a safe alternative to radical surgery for clinical T2N0 mid to low rectal cancer.

Cell sorting based on pulse shapes from angle resolved detection of scattered light.

Flow cytometry is a key technology for the analysis and sorting of cells or particles at high throughput. Conventional and current flow cytometry is primarily based on fluorescent stains to detect the cells of interest. However, such stains also have disadvantages, as their effect on cells must be carefully tested to avoid effects on the results of the experiments. Alternative approaches using imaging or other label-free techniques often require highly sophisticated setups, are commonly limited in resolution, and produce challenging amounts of data. Our technology exploits scattered light instead. The custom-built flow cytometry setup comprises a fiber array in forward scatter detection for angular resolution and captures the whole pulse shape with advanced signal processing. Thereby this setup enables cell analysis and sorting purely based on scattered light signals without the need for fluorescent labels. We demonstrate the feasibility of this cell sorting technology by sorting cell lines for their cell cycle stages based on scattered light. Furthermore, we demonstrate the ability to classify human peripheral blood T- and B-cell subsets.

Atomic-Level Observation of Potential-Dependent Variations at the Surface of an Oxide Catalyst during Oxygen Evolution Reaction.

Understanding the intricate details of the surface atomic structure and composition of catalysts during the oxygen evolution reaction (OER) is crucial for developing catalysts with high stability in water electrolyzers. While many notable studies highlight surface amorphization and reconstruction, systematic analytical tracing of the catalyst surface as a function of overpotential remains elusive. Heteroepitaxial (001) films of chemically stable and lattice-oxygen-inactive LaCoO3 are thus utilized as a model catalyst to demonstrate a series of atomic-resolution observations of the film surface at different anodic potentials. The first key finding is that atoms at the surface are fairly dynamic even at lower overpotentials. Angstrom-scale atomic displacements within the perovskite framework are identified below a certain potential level. Another noteworthy feature is that amorphization (or paracrystallization) with no long-range order is finally induced at higher overpotentials. In particular, surface analyses consistently support that the oxidation of lattice oxygen is coupled with amorphous phase formation at the high potentials. Theoretical calculations also reveal an upward shift of oxygen 2p states toward the Fermi level, indicating enhanced lattice oxygen activation when atom displacement occurs more extensively. This study emphasizes that the degradation behavior of OER catalysts can distinctively vary depending on the overpotential level.

Mitochondrial DNA mosaicism in normal human somatic cells.

Somatic cells accumulate genomic alterations with age; however, our understanding of mitochondrial DNA (mtDNA) mosaicism remains limited. Here we investigated the genomes of 2,096 clones derived from three cell types across 31 donors, identifying 6,451 mtDNA variants with heteroplasmy levels of ≳0.3%. While the majority of these variants were unique to individual clones, suggesting stochastic acquisition with age, 409 variants (6%) were shared across multiple embryonic lineages, indicating their origin from heteroplasmy in fertilized eggs. The mutational spectrum exhibited replication-strand bias, implicating mtDNA replication as a major mutational process. We evaluated the mtDNA mutation rate (5.0 × 10-8 per base pair) and a turnover frequency of 10-20 per year, which are fundamental components shaping the landscape of mtDNA mosaicism over a lifetime. The expansion of mtDNA-truncating mutations toward homoplasmy was substantially suppressed. Our findings provide comprehensive insights into the origins, dynamics and functional consequences of mtDNA mosaicism in human somatic cells.

Single-position oblique lumbar interbody fusion with navigation: improved efficiency and screw accuracy compared to dual-position with fluoroscopy.

Dual-position oblique lumbar interbody fusion with fluoroscopy (D-OLIF) requires repositioning the patient to a prone position for pedicle screw insertion. Recently, single-position surgery with navigation has been introduced. However, there are concerns regarding pedicle screw accuracy and achieving appropriate sagittal balance in single-position OLIF with navigation (S-OLIF). The purpose of this study is to evaluate the clinical and radiological outcomes of S-OLIF compared to D-OLIF. A retrospective analysis was conducted on 102 patients who underwent single-level OLIF at a single institution. The patients were divided into two groups: 55 in the S-OLIF group and 47 in the D-OLIF group. The numeric rating scale for back and leg, Oswestry disability index, and walking distance improvements showed no significant difference. However, the EuroQol 5-dimension 5-level index showed higher improvement in the S-OLIF (P = 0.029). The segmental lordosis, lumbar lordosis, and C7 sagittal vertical axis showed no significant difference. S-OLIF had significantly fewer cases of pedicle screw malposition (P = 0.045). Additionally, the surgery time was shorter in the S-OLIF (P = 0.002). In conclusion, S-OLIF exhibited clinical and radiological outcomes comparable to D-OLIF, with the added advantages of reduced surgery time and enhanced accuracy in pedicle screw placement.

Surgical Strategy for Dumbbell-Shaped Cervical Schwannoma at the Vicinity of the Vertebral Artery: The Utilization of Anatomic Layer.

BACKGROUND AND OBJECTIVES: In cases where dumbbell-shaped cervical schwannoma encases the vertebral artery (VA), there is a risk of VA injury during surgery. The objective of this study is to propose a strategy for preserving the VA during the surgical excision of tumors adjacent to the VA through the utilization of anatomic layers. METHODS: A retrospective analysis was conducted on 37 patients who underwent surgery for dumbbell-shaped cervical schwannoma with contacting VA from January 2004 to July 2023. The VA encasement group consisted of 12 patients, and the VA nonencasement group included 25 patients. RESULTS: The perineurium acted as a protective barrier from direct VA exposure or injury during surgery. However, in the VA encasement group, 1 patient was unable to preserve the perineurium while removing a tumor adjacent to the VA, resulting in VA injury. The patient had the intact dominant VA on the opposite side, and there were no new neurological deficits or infarctions after the surgery. Gross total resection was achieved in 25 patients (67.6%), while residual tumor was confirmed in 12 patients (32.4%). Four patients (33.3% of 12 patients) underwent reoperation because of the regrowth of the residual tumor within the neural foramen. In the case of the 8 patients (66.7% of 12 patients) whose residual tumor was located outside the neural foramen, no regrowth was observed, and there was no recurrence of the tumor within the remaining perineurium after total resection. CONCLUSION: In conclusion, when resecting a dumbbell-shaped cervical schwannoma contacting VA, subperineurium dissection prevents VA injury because the perineurium acts as a protective barrier.

A Pilot Study for Effectiveness and Safety of Adjunctive Pharmacopuncture to Acupuncture Treatment for Rotator Cuff Diseases: A Pragmatic Randomized Controlled Trial.

Purpose: Pharmacopuncture therapy has been used in the conservative treatment of rotator cuff disease adjuvant to acupuncture treatment. Despite the increasing utilization of pharmacopuncture therapy, there is still a lack of high-quality research to support its effectiveness. This pilot study aimed to assess the feasibility of pharmacopuncture therapy adjuvant to acupuncture treatment for rotator cuff disease. Patients and Methods: This was a parallel-grouped, pragmatic randomized controlled, pilot study. Forty patients were randomly allocated to either the experimental or the control group. All patients received acupuncture treatment for four weeks, and pharmacopuncture was additionally administered to the experimental group. After eight treatments were delivered over four weeks, follow-up assessments were performed. The primary outcome was the mean change in the visual analog scale (VAS) score for shoulder pain from baseline to visit 8. Secondary outcomes included shoulder pain and disability index (SPADI) at visits 4, 8, and 9, shoulder range of motion (ROM) at visits 4, 8, and 9, EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) at visits 8 and 9, patient global impression of change (PGIC) at visits 8 and 9, and mean rescue medication consumption at visits 8 and 9. Results: Both groups showed that each treatment effectively improved rotator cuff disease in most assessments. Particularly, the group that received acupuncture plus pharmacopuncture required fewer rescue medications than the group that received acupuncture alone. However, there was little statistically significant difference between the two groups. There were no serious adverse events experienced by patients in this study. Conclusion: Although there was little statistical difference between the two groups, the combination of acupuncture and pharmacopuncture for rotator cuff disease was associated with a reduction in the rescue medicine dosage compared with acupuncture alone. Also, it confirmed the safety of pharmacopuncture therapy. This pilot study would help design future research on the effectiveness of pharmacopuncture in rotator cuff disease.

Long-term survival analysis of robotic esophagectomy for esophageal cancer.

Robotic esophagectomy has improved early outcomes and enhanced the quality of lymphadenectomy for esophageal cancer surgery. This study aimed to determine risk factors for long-term survival following robotic esophagectomy and the causes of long-term mortality. We included patients who underwent robotic esophagectomy at our institute between 2010 and 2022. Robotic esophagectomy was defined as a surgical procedure performed robotically in both the abdomen and thorax. Robotic esophagectomy was performed in patients at all stages, including advanced stages, even in patients with stage IV and supraclavicular lymph node metastasis. A total of 340 patients underwent robotic esophagectomy during the study period. Ivor-Lewis operation and McKeown operation were performed on 153 (45.0%) and 187 (55.0%) patients, respectively. The five-year survival rates based on clinical stages were as follows: 85.2% in stage I, 62.0% in stage II, 54.5% in stage III, and 40.3% in stage IV. Risk factors for long-term survival included body mass index, Charlson comorbidity index, clinical stages, and postoperative complications of grade 4 or higher. Among the cases of long-term mortality, recurrence accounted for 42 patients (61.7%), while non-cancer-related death occurred in 26 patients (38.2%). The most common cause of non-cancer-related death was malnutrition and poor general condition, observed in 11 patients (16.2%). Robotic esophagectomy has demonstrated the ability to achieve acceptable long-term survival rates, even in patients with cervical lymph node metastasis. However, addressing high-grade postoperative complications and long-term malnutrition remains crucial for further improving the long-term survival outcomes of patients with esophageal cancer.
