Article Synopsis
  • - The study focuses on a new automated immunoassay for measuring CXCL9, a biomarker linked to type 1 inflammation, which could help in assessing various health conditions, including COVID-19 and asthma.
  • - The assay demonstrated reliable performance, with minimal variation (7%) over five days and a low limit of quantitation (2.2 pg/mL), ensuring it can effectively detect CXCL9 levels in plasma or serum.
  • - Findings showed that patients with acute COVID-19, asthma, and certain lung diseases had significantly higher CXCL9 levels compared to healthy individuals, indicating the assay’s potential clinical utility in inflammation-related conditions.

Background: Cardiovascular surgery in older patients with sarcopenia has high rates of major complications, long hospital stays, readmissions, and discharge transfers. However, the factors that influence the length of hospital stay are unknown. This study aimed was to identify the predictors of the prolonged hospital stay in patients with sarcopenia after cardiovascular surgery.

Background: A gastrointestinal stromal tumor rupture entails a high risk of recurrence even after curative surgery. However, the definition of rupture is unclear, and the question of whether patients with a minor rupture should be treated with adjuvant imatinib remains controversial.

Methods: The present, retrospective, multicentric study enrolled 57 patients with gastrointestinal stromal tumor with a minor/major tumor rupture, of whom 46 were finally found to be eligible for analysis.

Article Synopsis
  • Intra-abdominal desmoid tumors are rare and can develop without common risk factors, making diagnosis challenging; the case study discusses two unusual instances with contrasting features.
  • The first patient, a 51-year-old man, presented with severe abdominal pain and a large tumor identified via ultrasound, which was surgically resected for further evaluation.
  • The second patient, a 41-year-old man, had a tumor invading the ureter found during routine checkups, leading to surgery for diagnosis and treatment; despite different imaging and growth patterns, both tumors exhibited similar pathology, confirming their classification as desmoid tumors.

Background: Chronic hypersensitivity pneumonitis (CHP) is a heterogeneous fibrotic interstitial pneumonia resulting from the immune response of susceptible individuals to inhaled antigens. Genetic predispositions have been suggested in CHP; however, the link between susceptibility genes and fibrotic progression has not been elucidated fully. Recent data suggest that variants in Toll-interacting protein gene (TOLLIP) are associated with lung diseases.

Article Synopsis
  • A study was conducted on patients who underwent cardiac surgery to evaluate the safety and effectiveness of low-intensity resistance training with blood flow restriction (KAATSU RT) on muscle strength and size.
  • 21 patients were divided into a control group and a KAATSU RT group, with the latter performing specific leg exercises twice a week for three months in addition to standard rehabilitation.
  • The results showed that KAATSU RT was safe and led to significant increases in muscle thickness, skeletal muscle mass, walking speed, and knee strength without any side effects.

A 77-year-old man was admitted to our hospital because of a positive occult blood test result and diagnosed as having left transverse colon cancer(cT2N0M0)on detailed examination. The patient underwent a sigmoidectomy for colon cancer 24 years previously. Three-dimensional(3D)-CT angiography was performed before the present operation.

  • * The results indicated that both skeletal muscle mass index (SMI) and PhA were significantly correlated with factors like age, grip strength, and nutritional status (measured by CONUT score), showing strong connections especially in males.
  • * The study concluded that PhA could serve as a valuable indicator of sarcopenia, malnutrition, and cachexia in patients, with specific cut-off values identified for different conditions based on sex.

An 85-year-old man was diagnosed with esophagogastric junctional adenocarcinoma, E=G, Type 2, por, 6 cm in size, cT4aN1M0, cStage ⅢA. He had a history of atherosclerosis obliterans and thoracoabdominal aortic aneurysm. Considering the comorbidities and life expectancy, we decided to perform chemotherapy without tumor resection.

The patient was a 72-year-old man who exhibited an abnormal shadow in the stomach in a series of medical check-ups of the upper gastrointestinal in August 20XX. It was diagnosed as gastric cancer(type 1)of the greater curvature of the MU region. Total gastrectomy, D2-11p dissection, and Roux-en-Y reconstruction were performed in October 20XX.

The patient was a 56-year-oldwoman. She presentedto a nearby doctor with a chief complaint of dysphagia andwas diagnosed with esophageal cancer by upper gastrointestinal endoscopy, resulting in a referral to our hospital. Upper gastrointestinal endoscopy revealeda semicircular type 1 lesion 29 to 32 cm from the incisors, andshe was diagnosedwith squamous cell carcinoma by biopsy.

A 70-year-oldwoman underwent colonoscopy as a follow-up examination for colon polyps, during which early-stage rectosigmoid cancer was detected. Endoscopic submucosal dissection(ESD)was performed to remove this lesion. Additional radical anterior resection was recommended according to the histological findings but the patient chose to undergo observation.

Article Synopsis
  • Three molecular targeted drugs are currently available to treat gastrointestinal stromal tumors (GISTs), which improve patient outcomes, though no treatment guidelines exist for GISTs with bone metastases.
  • The case study details a 56-year-old male diagnosed with leiomyosarcoma who later developed GIST, leading to multiple metastases and a series of treatments, including surgery, radiotherapy, and medications like imatinib and sunitinib.
  • Despite treatments that stabilized his condition initially, the patient ultimately experienced progressive disease and passed away in 2014, illustrating the challenges of managing GIST with bone metastases but also the potential for extended survival with a multidisciplinary approach.

Blood flow restriction (BFR) has the potential to augment muscle activation, which underlies strengthening and hypertrophic effects of exercise on skeletal muscle. We quantified the effects of BFR on muscle activation in the rectus femoris (RF), the vastus lateralis (VL), and the vastus medialis (VM) in concentric and eccentric contraction phases of low-intensity (10% and 20% of one repetition maximum) leg extension in seven cardiovascular patients who performed leg extension in four conditions: at 10% and 20% intensities with and without BFR. Each condition consisted of three sets of 30 trials with 30 s of rest between sets and 5 min of rest between conditions.

Pulmonary enteric adenocarcinoma is a unique pulmonary adenocarcinoma subtype and has histopathological findings that are similar to those of colorectal adenocarcinoma. A man in his 50s visited our hospital because of discomfort in his right lower leg for the last 9 months. Imaging studies revealed a mass in his right soleus muscle, and needle biopsy was performed.

Objective: Combination treatment with ramucirumab and paclitaxel shows significant efficacy in patients with advanced gastric cancer as a second-line standard therapy. However, limited information is available about the development of pneumonitis associated with this treatment in clinical practice. This study aimed to characterize this form of pneumonitis and identify the risk factors for its onset.

We examined the relationship between Short Physical Performance Battery (SPPB) and clinical and laboratory factors and the effect of sarcopenia and sarcopenic obesity (SO) on clinical and laboratory factors for cardiovascular disease (CVD) inpatients. CVD male (n = 318) and female (n = 172) inpatients were recruited. A stepwise multiple-regression analysis was performed to predict total SPPB scores and assess clinical and laboratory factors (physical characteristics, functional and morphological assessments, etc.

Background: In a recent study, it was reported that transcatheter arterial embolization with spherical embolic material for life-threatening hemorrhages in various cancer patients was safe and effective. Calibrated microspheres are able to access distal regions of the target arteries, which results in the disappearance of tumor staining. However, there are few reports on the pathological behavior of EmboSpheres in gastric cancer specimens.
