We conducted a risk-adapted upfront docetaxel (DOC) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). Here, we reported an interim analysis of the study. The study enrolled 68 patients with newly diagnosed mHSPC between 2016 and 2018. According to the presence of visceral metastasis, an EOD score ≥ 3, or prostate-specific antigen (PSA) level at 3 months of ≥ 1 ng/mL, patients were divided into low- and high-risk groups. Patients were treated with androgen deprivation therapy (ADT) with or without bicalutamide; those in the high-risk group received upfront treatment involving six cycles of DOC (70 mg/m2). Short-term treatment effect, adverse events, and quality of life (QOL) were evaluated. Fifty (73.5%) were classified in the high-risk group, and 46 (67%) received upfront ADT + DOC. In the ADT + DOC group, 43.5% (20/46) patients achieved a PSA level ≤ 0.2 ng/mL. PSA nadir and time to PSA nadir were 0.291 ng/mL and 288 days, respectively. In the ADT + DOC group, 76.1% (35/42) patients had adverse events (AEs) of grade ≥ 3. During a median follow-up of 18.5 months, 36.4% (8/22) patients in the ADT group and 43.5% (20/46) in the ADT + DOC group had CRPC. Two QOL scores including the physical status and appetite loss at 6 months significantly worsened in the ADT + DOC group but was resolved by 12 months. Upfront DOC achieved high PSA responses without long-term QOL deterioration. However, the short-term outcomes were limited. Longer follow-up is needed to determine the survival advantage.

To compare the efficacy and adherence rates of two parallel home exercise therapy programs—multiple exercise (training and stretching the knee and hip muscles) and control (training the quadriceps muscles)—on knee pain, physical function, and knee extension strength in community-dwelling elderly individuals with pre-radiographic knee osteoarthritis (OA). One hundred patients with medial knee pain were randomly allocated to one of two 4-week home exercise programs. Individuals with a Kellgren/Lawrence (K/L) grade 0 or 1 OA (pre-radiographic knee OA) in the medial compartment were enrolled. Primary outcomes were knee pain (visual analog scale), self-reported physical function (Japanese Knee Osteoarthritis Measure [JKOM]), and isometric maximum muscle strength of the knee extensor measured using a hand-held dynamometer. A total of 52 patients (28 [53.8%] in the multiple exercise group, 24 [46.2%] in the control group) completed the trial. The JKOM activities of daily living and general health conditions outcomes improved significantly in the multiple exercise group compared to the control group (JKOM activities of daily living, beta = − 0.76; 95% confidence interval [CI], − 1.39 to − 0.13; p = 0.01; JKOM general health conditions, beta = − 0.25; 95% CI, − 0.48 to − 0.01; p = 0.03). The home exercise compliance rates of the multiple exercise and control groups were 96.6 and 100%, respectively. When targeting pre-radiographic knee OA in community-dwelling elderly, it is important to implement home exercise programs that aim to improve muscle strength and joint flexibility rather than knee extension muscle power only.

We encountered a case of a large hematoma developing with perforation shortly after a cold snare polypectomy for a colorectal adenoma. The patient underwent cold snare polypectomy for a 3‐mm type Is lesion in the transverse colon at another facility. Two hours later, she visited the emergency room due to abdominal pain. Contrast‐enhanced computed tomography revealed a 70 mm, high‐intensity mass in the transverse colon with contrast extravasation. We attempted transcatheter arterial embolization to stop the bleeding. Several hours later, the anemia had not worsened, but the severe abdominal pain persisted. Urgent laparoscopic right hemicolectomy was performed due to the possibility of gastrointestinal perforation. The surgery was successfully completed. Pathology reports confirmed the presence of an intramural hematoma in the proximal transverse colon with hemorrhagic infiltration of all layers, along with extensive ischemic changes. A perforation was identified in this area, with mucosal defects observed near the hole, possibly due to cold snare polypectomy.

Hallux valgus is the most common forefoot deformity and affects the transverse arch structure and its force loading patterns. This study aims to clarify the differences in the transverse arch structure and the force under the metatarsal heads individually, between normal feet and hallux valgus feet, and between hallux valgus feet with pain and without pain. We further test the association between the parameters of the transverse arch and hallux valgus angle and between the parameters and pain in hallux valgus. Women's feet (105 feet) were divided into normal group (NORM) and hallux valgus group (HVG); and further into subgroups: hallux valgus without pain (HV Pain (-)) and hallux valgus with pain (HV Pain (+)). Transverse arch height and metatarsal heads height were measured using weight-bearing ultrasound imaging. Force under the metatarsal heads was measured using force sensors attached directly on the skin surface of the metatarsal heads. The measurements were taken in three loading positions: sitting, quiet standing and 90% weight shift on the tested foot. Differences between the groups were compared using Student t-test and Wilcoxon Exact test. Multivariate logistic analysis with adjustment for physical characteristics was also conducted. Transverse arch height was significantly higher in HVG than in NORM in all positions; there were no significant differences between HV Pain (+) and HV pain (-). Lateral sesamoid was significantly higher in HVG and HV Pain (+) than in NORM and HV Pain (-) respectively when bearing 90% of the body weight unilaterally. There was a trend of higher forces under the medial forefoot without significant difference. Transverse arch height and lateral sesamoid height were associated with the hallux valgus angle, while lateral sesamoid height was associated with forefoot pain in hallux valgus deformity. This study shows the differences in the transverse arch structure between normal feet and feet with hallux valgus, and between hallux valgus feet with and without pain. This finding is noteworthy when considering future treatments of painful feet, notably the height of the lateral sesamoid which seems to play a role in forefoot pain.

Background LBP is a common and serious problem affecting vast populations of the world. However, only few studies on LBP in sub-Saharan Africa have been conducted. Studies report that LBP and pelvic angle are interrelated, and African residents have a high pelvic tilt. The strategy to prevent LBP should focus on activities that promote holistic health. For that purpose, it is important to grasp the state of LBP and how it affects people’s lifestyle in Tanzania to clarify the direction of implementation of physiotherapy treatment and reduce the incidences of LBP among adults. This study aimed to investigate the prevalence and presentation of low back pain (LBP) and the relationship between anthropometric measurements and LBP among people in Moshi city, Kilimanjaro region Tanzania. Methods Following signing consent forms, participants were given questionnaires regarding LBP and then grouped accordingly into either asymptomatic or symptomatic cohorts. Anthropometric measurements of participants’ height, weight, curvature of the spine, and pelvic angle were obtained. Results A Mann-Whitney U test analysis showed a significant difference in pelvic angle, body mass index (BMI), and thoracic kyphosis angle between the asymptomatic group and the symptomatic group. No significant differences in lumbar lordosis angle or abdominal muscle strength were found between the two groups. Conclusions A person with symptomatic LBP in Tanzania has a large anteversion of the pelvic tilt and a thoracic kyphotic posture. This study shows a relationship between sagittal spinal alignment and LBP in Tanzania, which could allow for prospective identification of subjects prone to developing LBP in the future.

High heeled shoes have long been worn in society and they are known to cause biomechanical imbalances to not only the foot, but the whole musculoskeletal system. This study aims to show the detailed changes that happen to the shape of the transverse arch of the foot in high heels, using two different inclination degrees. 68 women participated in this study. Two custom-made high heels were made with inclinations of 15 degrees and 30 degrees (cm). A weight-bearing ultrasound was used to assess the coronal view of the transverse arch in standing. ANOVA and Tuckey tests were used to compare the results between 0 degrees, 15 degrees and 30 degrees inclinations. The transverse arch height was slightly increased as the heel height increased (0DI-15DI: p = 0.5852 / 15DI-30DI: p = 0.395 / 0DI-30DI: p = 0.0593). The transverse arch length (0DI-15DI: p = 0.0486 / 15DI-30DI: p = 0.0004 / 0DI-30DI: p = 0.1105) and the area under the metatarsal heads (0DI-15DI: p = 0.0422 / 15DI-30DI: p = 0.0180 / 0DI-30DI: p = 0.9463) significantly decreased as the heel height increased. The main changes were viewed in the 30 degrees inclinations compared to 0 degrees inclination. When the toes are dorsiflexed in high heels, it stimulates the Windlass mechanism which in turn stiffens the plantar fascia and adducts the metatarsal heads, while the soft tissues shrink in response to loads. High heels affected the shape of the transverse arch even in short term standing, and these effects increased as the height of the heel increased.

This study aimed to develop a self-questionnaire index relevant to lower limb functional assessment reflecting clinical symptoms and activity restrictions associated with activities of daily living (ADL) for patients with knee osteoarthritis. This cross-sectional study enrolled patients with knee osteoarthritis (Kellgren/Lawrence grade ≥ 1). Participants evaluated clinical symptoms and activity restrictions using self-reported questionnaires. Radiographic evaluation, knee joint range of motion (ROM), and lower limb muscle strength were assessed. Associations between clinical symptoms, activity restrictions, and knee and hip joint function were evaluated using multiple and logistic regression analysis. Overall, 142 participants were included in the final analysis. Patients with knee pain while rising from a chair had lower knee and hip extension strength (knee extension β = − 0.28; 95% confidence interval (CI), − 0.41 to − 0.14; P < 0.0001; hip extension β = − 0.26; 95% CI, − 0.42 to − 0.08; P = 0.0034), and restricted knee extension ROM (odds ratio [OR] = 2.17; 95% CI, 1.02–4.63; P = 0.041). Patients with knee pain during stair climbing, turning or who were unable to stand on one leg without external support had reduced hip abduction muscle strength (β = − 0.17; 95% CI, − 0.27 to − 0.07; P = 0.0008). Patients with knee pain while rising from a chair or stepping showed more severe knee joint degeneration on radiographic evaluation (OR = 3.26; 95% CI, 1.11–10.91; P = 0.03). The self-questionnaire index reflected clinical symptoms and activity restrictions associated with ADL and was significantly associated with lower limb function in individuals with knee osteoarthritis.

We assessed whether radon inhalation provided protection from carbon tetrachloride (CCl 4 )-induced hepatic and renal damage in mice. Mice were subjected to intraperitoneal injection of CCl 4 after inhaling approximately 18 kBq/m 3 radon for 6 h. Radon inhalation significantly increased total glutathione (t-GSH) content and glutathione peroxidase (GPx) activity in the liver and kidney. Injection of CCl 4 was associated with significantly higher levels of glutamic oxaloacetic transaminase (GOT) and alkaline phosphatase (ALP) activity and creatinine level in serum, and pretreatment with radon significantly decreased the GOT and ALP activity and creatinine level associated with CCl 4 injection, suggesting that radon inhalation alleviates CCl 4 -induced hepatic and renal damage. The t-GSH contents and GPx activity in the liver and kidney of animals pretreated with radon were significantly higher than those of the CCl 4 -only group. These findings suggested that radon inhalation activated antioxidative functions and inhibited CCl 4 -induced hepatic and renal damage in mice.

This paper describes a system to autonomously measure the shape of an unknown physical object for constructing the computer model of a physical object. The system is composed of two subsystems: one is for the rough recognition of a physical object and the other is for the precise measurement. A physical object is roughly recognized as the Z-map model that is constructed by analyzing and processing the shadow images of an object obtained by CCD cameras. The precise measurement of discrete points on the object is autonomously made according to the Z-map model using a three-coordinate measuring machine.

This paper presents a knowledge management system for automobile failure analysis using retrieval-augmented generation (RAG) with large language models (LLMs) and knowledge graphs (KGs). In the automotive industry, there is a growing demand for knowledge transfer of failure analysis from experienced engineers to young engineers. However, failure events are phenomena that occur in a chain reaction, making them difficult for beginners to analyze them. While knowledge graphs, which can describe semantic relationships and structure information is effective in representing failure events, due to their capability of representing the relationships between components, there is much information in KGs, so it is challenging for young engineers to extract and understand sub-graphs from the KG. On the other hand, there is increasing interest in the use of Graph RAG, a type of RAG that combines LLMs and KGs for knowledge management. However, when using the current Graph RAG framework with an existing knowledge graph for automobile failures, several issues arise because it is difficult to generate executable queries for a knowledge graph database which is not constructed by LLMs. To address this, we focused on optimizing the Graph RAG pipeline for existing knowledge graphs. Using an original Q&A dataset, the ROUGE F1 score of the sentences generated by the proposed method showed an average improvement of 157.6% compared to the current method. This highlights the effectiveness of the proposed method for automobile failure analysis.
