RESUMEN
Importance: There is currently no consensus on clinically effective interventions for polypharmacy among older inpatients. Objective: To evaluate the effect of multidisciplinary team-based medication optimization on survival, unscheduled hospital visits, and rehospitalization in older inpatients with polypharmacy. Design, Setting, and Participants: This open-label randomized clinical trial was conducted at 8 internal medicine inpatient wards within a community hospital in Japan. Participants included medical inpatients 65 years or older who were receiving 5 or more regular medications. Enrollment took place between May 21, 2019, and March 14, 2022. Statistical analysis was performed from September 2023 to May 2024. Intervention: The participants were randomly assigned to receive either an intervention for medication optimization or usual care including medication reconciliation. The intervention consisted of a medication review using the STOPP (Screening Tool of Older Persons' Prescriptions)/START (Screening Tool to Alert to Right Treatment) criteria, followed by a medication optimization proposal for participants and their attending physicians developed by a multidisciplinary team. On discharge, the medication optimization summary was sent to patients' primary care physicians and community pharmacists. Main Outcomes and Measures: The primary outcome was a composite of death, unscheduled hospital visits, and rehospitalization within 12 months. Secondary outcomes included the number of prescribed medications, falls, and adverse events. Results: Between May 21, 2019, and March 14, 2022, 442 participants (mean [SD] age, 81.8 [7.1] years; 223 [50.5%] women) were randomly assigned to the intervention (n = 215) and usual care (n = 227). The intervention group had a significantly lower percentage of patients with 1 or more potentially inappropriate medications than the usual care group at discharge (26.2% vs 33.0%; adjusted odds ratio [OR], 0.56 [95% CI, 0.33-0.94]; P = .03), at 6 months (27.7% vs 37.5%; adjusted OR, 0.50 [95% CI, 0.29-0.86]; P = .01), and at 12 months (26.7% vs 37.4%; adjusted OR, 0.45 [95% CI, 0.25-0.80]; P = .007). The primary composite outcome occurred in 106 participants (49.3%) in the intervention group and 117 (51.5%) in the usual care group (stratified hazard ratio, 0.98 [95% CI, 0.75-1.27]). Adverse events were similar between each group (123 [57.2%] in the intervention group and 135 [59.5%] in the usual care group). Conclusions and Relevance: In this randomized clinical trial of older inpatients with polypharmacy, the multidisciplinary deprescribing intervention did not reduce death, unscheduled hospital visits, or rehospitalization within 12 months. The intervention was effective in reducing the number of medications with no significant adverse effects on clinical outcomes, even among older inpatients with polypharmacy. Trial Registration: UMIN Clinical Trials Registry: UMIN000035265.

BACKGROUND: Six percent of patients with Leigh syndrome (LS) present with infantile epileptic spasms syndrome (IESS). However, treatment strategies for IESS with LS remain unclear. This retrospective study aimed to evaluate the efficacy and safety of treatment strategies in patients with IESS complicated by LS and Leigh-like syndrome (LLS). METHODS: We distributed questionnaires to 750 facilities in Japan, and the clinical data of 21 patients from 15 hospitals were collected. The data comprised treatment strategies, including adrenocorticotropic hormone (ACTH) therapy, ketogenic diet (KD) therapy, and antiseizure medications (ASMs); effectiveness of each treatment; and the adverse events. RESULTS: The median age at LS and LLS diagnosis was 7 months (range: 0 to 50), whereas that at the onset of epileptic spasms was 7 (range: 3 to 20). LS was diagnosed in 17 patients and LLS in four patients. Seven, two, five, and seven patients received ACTH + ASMs, ACTH + KD + ASMs, KD + ASMs, and ASMs only, respectively. Four (44%) of nine patients treated with ACTH and one (14%) of seven patients treated with KD achieved electroclinical remission within one month of treatment. No patients treated with only ASMs achieved electroclinical remission. Seven patients (33%) achieved electroclinical remission by the last follow-up. Adverse events were reported in four patients treated with ACTH, none treated with KD therapy, and eight treated with ASMs. CONCLUSION: ACTH therapy shows the best efficacy and rapid action in patients with IESS complicated by LS and LLS. The effectiveness of KD therapy and ASMs in this study was insufficient.

Eosinophilic gastritis (EoG) is defined as the presence of upper gastrointestinal symptoms combined with histologic findings of > 30 eosinophils/high-power field (eos/hpf) in 5 hpf in any part of the gastric mucosa, except for the secondary causes of gastric eosinophilia. This is the first case report of a serial change in gastric motility in EoG with pyloric stenosis using abdominal ultrasonography. A 56-year-old woman was diagnosed with pyloric stenosis by upper gastrointestinal radiographic examination during a medical checkup. She had nausea and loss of appetite, her gastrointestinal symptom rating scale (GSRS) score was 20, and her F scale score was 20. Esophagogastroduodenoscopy (EGD) demonstrated pyloric stenosis and multiple superficial ulcerations in the antrum. Histopathological findings of gastric biopsy specimens revealed severe eosinophilic infiltration (100 eos/HPF), and the diagnosis was EoG with pyloric stenosis. Before treatment, the gastric anterior wall thickness was 6.3 mm. The gastric motility in EoG was evaluated by intra-abdominal ultrasonography. Ultrasonography showed low motility in the antrum, especially the amplitude and motility index. After 6 months of steroid treatment, her symptoms improved. Her GSRS score was 13, and her F scale score was 19. Histological eosinophilic infiltration decreased to 50 eos/HPF, showing improvement. On ultrasonography, gastric motility also improved and recovered to normal. After 12 months, several examinations confirmed improvement, including gastric motility by ultrasonography.
RESUMEN
PURPOSE: To establish if osteosarcopenia is related to postoperative complications, prognosis, and recurrence of colorectal cancer (CRC) after curative surgery. METHODS: The clinical data of 594 patients who underwent curative resection for CRC between January, 2013 and December, 2018 were analyzed retrospectively to examine the relationship between clinicopathological data and osteosarcopenia. The following definitions were used: sarcopenia, low skeletal muscle mass index; osteopenia, low bone mineral density on computed tomography at the level of the 11th thoracic vertebra; and osteosarcopenia, sarcopenia with osteopenia. RESULTS: Osteosarcopenia was identified in 98 patients (16.5%) and found to be a significant risk factor for postoperative complications (odds ratio 2.53; p = 0.011). The 5-year overall survival (OS) and recurrence-free survival (RFS) rates of the patients with osteosarcopenia were significantly lower than those of the patients without osteosarcopenia (OS: 72.5% and 93.9%, respectively, p < 0.0001; RFS: 70.8% and 92.4%, respectively, p < 0.0001). Multivariate analysis identified osteosarcopenia as an independent prognostic factor associated with OS (hazard ratio 3.31; p < 0.0001) and RFS (hazard ratio 3.67; p < 0.0001). CONCLUSION: Osteosarcopenia may serve as a predictor of postoperative complications and prognosis after curative surgery for CRC.
RESUMEN
Laparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen-sparing. We report a case of a 25-year-old female who underwent laparoscopic fenestration for a giant splenic cyst using a single-incision plus one-port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5-cm umbilical incision, and a 5-mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post-operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single-incision plus one-port is considered to be an appropriate procedure for giant splenic cysts with non-serous contents.

The only reliable factor that reduces the risk of colorectal carcinogenesis is physical activity. However, the underlying mechanisms remain unclear. In this study, we examined the effects of physical activity against gut microbiota, including mucosa-associated microbiota (MAM) on azoxymethane-induced colorectal tumors in obese mice. We divided the subjects into four groups: normal diet (ND), high-fat diet (HFD), ND + exercise (Ex), and HFD + Ex groups. The Ex group performed treadmill exercise for 20 weeks. Thereafter, fecal and colonic mucus samples were extracted for microbiota analysis. DNA was collected from feces and colonic mucosa, and V3-V4 amplicon sequencing analysis of the 16SrRNA gene was performed using MiSeq. The HFD group had significantly more colonic polyps than the ND group (ND 6.5 ± 1.3, HFD 11.4 ± 1.5, p < 0.001), and the addition of Ex suppressed the number of colonic polyps in ND and HFD groups (ND 6.5 ± 1.3, ND + Ex 2.8 ± 2.5, p < 0.05). The HFD group showed significantly lower concentrations of succinic, acetic, butyric, and propionic acids (mg/g) in feces, compared with the ND group (succinic acid HFD 0.59, ND 0.17; acetic acid HFD 0.63, ND 2.41; propionic acid HFD 0.10, ND 0.47; and N-butyric acid HFD 0.31, ND 0.93). In the case of ND, succinic acid and butyric acid tended to decrease with Ex (succinic acid ND 0.17, ND + Ex 0.12; N-butyric acid ND 0.93, ND + Ex 0.74 0.74). Succinic acid, acetic acid, butyric acid, and propionic acid levels in feces were significantly lower in the HFD group than in the ND group; in both feces and mucus samples, Butyricicoccus and Lactobacillus levels were significantly lower in the HFD group. Akkermansia was significantly increased in ND + Ex and HFD + Ex groups. Diet and exercise affected the number of colorectal tumors. Furthermore, diet and exercise alter intestinal MAM, which may be involved in colorectal tumor development.
RESUMEN
PURPOSE: In our previous study, we confirmed that the supplementation of vitrified-warmed murine oocytes with autologous adipose stem cell (ASC)-derived mitochondria during intracytoplasmic sperm injection enhances post-fertilization developmental competence in mice. To ensure the safety of this technology, we conducted a thorough study in mice to investigate the potential presence of specific malformations in offspring developed from this approach. METHODS: A transgenerational comparative analysis was conducted on founder mice from embryos that developed after mitochondrial supplementation, and two subsequent generations. Reproductive performance, body growth rate, histopathological parameters, hematological parameters, daily activity patterns, and daily body temperature changes in male and female mice across these three generations were assessed in comparison to wild-type mice of the same age. RESULTS: Both male and female animals in all three generations showed comparable reproductive performance to the control group. Additionally, body growth rate by the age of 8 weeks were found to be comparable to controls across all three generations. Notably, no significant histopathological abnormalities were detected in vital organs, including the brain, heart, liver, kidneys, lungs, ovaries, and testes, in any individuals from the studied cohorts. The blood parameters were consistent with the control data. The continuous monitoring of activity and body temperature changes (both day and night) over a 1-week period revealed a pattern closely resembling that observed in the control animals. CONCLUSION: Injection of ASC-mitochondria into oocytes may be a promising technique to support developmental potential without causing adverse epigenetic events in the offspring in mice. However, before considering clinical application, additional safety screening using larger animals or non-human primates is essential.
RESUMEN
BACKGROUND/AIM: There are two main subtypes of mucinous carcinoma (MC) based on the quantification of the mucinous component: the pure variant (pMC) and the mixed variant (mMC). pMC has been subdivided into pure A with a hypocellular variant, and pure B with a hypercellular variant. PATIENTS AND METHODS: We retrospectively analyzed the clinicopathological features of 99 patients with MC who were treated at our institution from January 2002 to December 2014. We evaluated the expression profiles of markers, including mucin (MUC) family members, in the patients groups representing different MC subtypes by performing immunohistochemistry to identify factors involved in the differentiation and progression of MCs. RESULTS: Among the 99 patients, 76 (76.8%) had pure mucinous carcinomas (pMC) and the other 23 (23.2%) had mixed mucinous carcinomas (mMC). Of the pMCs, 54 were pure A and 22 were pure B. The prognosis was worse for pure B than pure A and worse for mMC than pMC. Although there was no significant difference in clinicopathological factors between the pure A and pure B groups, immunohistochemical staining revealed differences in the localization of mucin MUC1 and ß-catenin. A comparison of the pMC and mMC cases revealed more lymphovascular invasion in mMC and differences in the localization of ß-catenin between the two groups. CONCLUSION: The patients' prognoses were significantly poorer depending on the histologic subtype (in the order pure A, pure B, and mixed). MUC1 localization and ß-catenin were revealed as independent predictors contributing to the poorer prognosis.

Cytokeratin (CK) is a specific marker of adenocarcinoma. However, cases of CK7-positive esophageal squamous cell carcinoma (ESCC) have only rarely been reported. We herein report a case of unresectable CK7-positive ESCC with aggressive liver metastasis following nivolumab treatment initiation. Nivolumab treatment was discontinued after one course because of complications. Notably, the liver metastases exhibited accelerated growth. Immunostaining of the necropsy specimens revealed diffuse positivity for forkhead box protein A1 (FOXA1)/CK7, thus indicating a potent poor immune response. The potential correlation between CK7 expression and the immune checkpoint inhibitor response may offer valuable insights into the development of effective therapeutic strategies.
RESUMEN
BACKGROUND: The pharyngeal flap (PF) is useful for reconstruction of soft palate defects, but effective arrangements of PF for various types of soft palate defects are controversial. Here, we classify three types of soft palate defects and discuss the arrangements of PF and their functional prognosis. METHODS: Reconstruction was performed based on the classification of the defects. Clinical details were collected, and postoperative function was analyzed. RESULTS: Eight patients were included in the study. The defect sizes ranged from 25 (width) × 40 (depth) to 40 × 60 mm. Six patients underwent pharyngeal flap reconstruction with free-flap reconstruction, and two underwent pharyngeal flap reconstruction. The pharyngeal flap was harvested at the maximum width of the posterior pharyngeal wall, ranging from 25 to 40 mm in length. Eating and speaking functions were maintained in all patients. CONCLUSIONS: Good postoperative function can be maintained by narrowing the velopharyngeal space with a pharyngeal flap.

INTRODUCTION: Cancer genome analysis using next-generation sequencing requires adequate and high-quality DNA samples. Genomic analyses were conventionally performed using formalin-fixed paraffin-embedded sections rather than cytology samples such as cell block or smear specimens. Specimens collected from liquid-based cytology (LBC) have the potential to be sources of high-quality DNA suitable for genetic analysis even after long-term storage. METHODS: We collected breast tumor/lesion fractions from 92 residual LBC specimens using fine-needle aspiration (FNA) biopsy, including breast carcinoma (1 invasive carcinoma and 4 ductal carcinomas in situ), papillomatous lesion (5 intraductal papillomas), and fibroepithelial lesion (19 phyllodes tumors and 53 fibroadenomas) samples, and others (1 ductal adenoma, 1 hamartoma, 1 fibrocystic disease, and 7 unknown). DNA was extracted from all samples and subjected to DNA integrity number (DIN) score analysis. RESULTS: Average DIN score collected from 92 LBC specimens was significantly higher score. In addition, high-quality DNA with high DIN values (7.39 ± 0.80) was successfully extracted more than 12 months after storage of residual LBC specimens. CONCLUSION: Residual LBC specimens collected from FNA of the breast were verified to carry high-quality DNA and could serve as an alternate source for genetic analysis.

BACKGROUND: Advanced surgical interventions are required to treat malignancies in the anterior skull base (ASB). This study investigates the utility of endoscopic endonasal and transcranial surgery (EETS) using a high-definition three-dimensional exoscope as an alternative to traditional microscopy. METHODS: Six patients with carcinomas of varying histopathologies underwent surgery employing the EETS maneuver, which synchronized three distinct surgical modalities: harvesting of the anterolateral thigh flap, initiation of the transnasal technique, and initiation of the transcranial procedure. RESULTS: The innovative strategy enabled successful tumor resection and skull base reconstruction without postoperative local neoplastic recurrence, cerebrospinal fluid leakage, or neurological deficits. CONCLUSION: The integration of the exoscope and EETS is a novel therapeutic approach for ASB malignancies. This strategy demonstrates the potential of the exoscope in augmenting surgical visualization, enhancing ergonomics, and achieving seamless alignment of multiple surgical interventions. This technique represents a progressive shift in the management of these complex oncological challenges.

This study investigated the effects of low doses of alcohol, which are acceptable for driving a car, on inhibitory control and neural processing using the stop-signal task (SST) in 17 healthy right-handed social drinkers. The study employed simultaneous functional magnetic resonance imaging and electromyography (EMG) recordings to assess behavioral and neural responses under conditions of low-dose alcohol (breath-alcohol concentration of 0.15 mg/L) and placebo. The results demonstrated that even a small amount of alcohol consumption prolonged Go reaction times in the SST and modified stopping behavior, as evidenced by a decrease in the frequency and magnitude of partial response EMG that did not result in button pressing during successful inhibitory control. Furthermore, alcohol intake enhanced neural activity during failed inhibitory responses in the right inferior frontal cortex, suggesting its potential role in behavioral adaptation following stop-signal failure. These findings suggest that even low levels of alcohol consumption within legal driving limits can greatly impact both the cognitive performance and brain activity involved in inhibiting responses. This research provides important evidence on the neurobehavioral effects of low-dose alcohol consumption, with implications for understanding the biological basis of impaired motor control and decision-making and potentially informing legal guidelines on alcohol consumption.

A rare case of an ascending colon injury and ileal perforation in a 34-year-old male patient due to blunt abdominal trauma caused by a road traffic accident is reported in this study. This paper reports the clinical and imaging findings of seat belt syndrome. The seat belt syndrome primarily involves soft tissue injury; however, lacerations of the colon, small intestine, and mesentery have rarely been reported in the literature. However intestinal injuries, including bowel perforation and mesenteric injuries due to seat belt syndrome, must not be underestimated because they usually require emergency laparotomy because of accompanying peritonitis and hemorrhaging, and can be lethal if left untreated. Therefore, when an ascending mesocolon hematoma and free gas in the peritoneal cavity are present, gastrointestinal perforation due to seat belt syndrome should be suspected. In this case, gastrointestinal perforation was suspected based on the computed tomography findings, and emergency surgery was performed; the patient's course was uneventful without any postoperative complications. Early diagnosis and management are essential to prevent associated morbidity and mortality.
RESUMEN
INTRODUCTION: Robot-assisted surgery is increasingly deployed in colorectal surgery, and decompression surgery using a stent is considered a standard treatment for malignant stenosis of the large intestine. Surgery after stent placement is also frequently performed. However, the anastomosis method remains controversial. PRESENTATION OF CASE: A 75-year-old woman visited our hospital's internal medicine department with chief complaints of bloody stool and constipation for the past year and colonoscopy was scheduled. After taking laxatives to prepare for treatment, abdominal pain was noticed and an emergency request was made. A diagnosis of colorectal malignant stricture and rectosigmoid junction cancer was made and a stent was placed during emergency colonoscopy. After intestinal decompression, a diagnosis of rectosigmoid junction cancer (UICC 8th; T3N0M0 Stage IIa) was rendered and robotic-assisted high anterior resection of the rectum and lymph node D3 dissection were performed. Reconstruction was performed using Gambee anastomosis outside the body cavity. The postoperative course was uneventful. DISCUSSION: The double stapling technique is simple, but in this case, the obstructed intestinal tract was swollen. Meanwhile, Gambee anastomosis, which allows adjustment of tightness, was considered effective. CONCLUSION: Gambee anastomosis is a valid option when robot-assisted rectal resection is performed after intestinal decompression with stent placement for malignant stricture of the rectosigmoid junction. It is important to select a hand-sewn or mechanical anastomosis by considering the condition of the organ to be anastomosed and the site of the anastomosis.

A 70-year-old man was diagnosed with early gastric cancer with ulcerative findings. Endoscopic submucosal dissection as an absolute indication was performed, and en bloc resection was achieved. Pathological examination revealed a well-differentiated adenocarcinoma, 3 × 2 mm in size, intramucosal, with an ulcerative scar, no lymphovascular invasion, and a tumor-free margin. We diagnosed it as a curative resection and followed up with annual endoscopy. Sixteen months after endoscopic submucosal dissection, esophagogastroduodenoscopy revealed a singular ulcer scar; however, serum carcinoembryonic antigen level was elevated. Computed tomography scan showed wall thickening of the gastric antrum and an irregular mass on the dorsal side. Additionally, 18F-fluorodeoxyglucose positron emission tomography/coomputed tomography showed 18F-fluorodeoxyglucose uptake in the gastric antrum, irregular mass, and liver. Endoscopic ultrasonography revealed an internally heterogeneous mass in the gastric antrum region extending from the submucosal layer to the muscularis propria layer. Using an endoscopic ultrasonography-guided fine needle biopsy with a 22-gauge needle for the mass, we diagnosed local recurrence with the submucosal tumor-like appearance, lymph node metastasis, and liver metastases. Unfortunately, the patient died of gastric cancer 3 months after the diagnosis. Here, we report a rare case of local recurrence in the submucosal layer, lymph node metastasis, and liver metastases 16 months after curative endoscopic submucosal dissection.
RESUMEN
Emergency appendectomy (EA) is the gold standard management for acute appendicitis (AA). However, whether EA or interval appendectomy (IA) after conservative treatment is the optimal approach in AA with abscess remains controversial. This study compared IA and EA in patients presenting with AA accompanied by abscess. This was a retrospective single-center study including 446 consecutive patients undergoing appendectomy between April 2009 and March 2023. AA with abscess was defined as a pericecal abscess observed by computed tomography or abdominal ultrasonography, and patients with signs of peritoneal irritation were excluded. Perioperative outcomes were compared between the patients who directly underwent EA and those who underwent IA after conservative treatment. Among 42 patients (9.4%) with AA and abscess, 34 and 8 patients underwent IA and EA, respectively. The rates of ileocecal resection and postoperative complications were lower in the IA group than in the EA group (3% vs. 50%, P < 0.001 and 9% vs. 75%, P < 0.001, respectively). Colonoscopy before IA was performed in 16 of the 17 patients aged ≥ 40 years in the IA group, and one patient underwent ileocecal resection because of suspicious neoplasm in the root of the appendix. IA after conservative treatment might be considered as the useful therapeutic option for AA with abscess. Colonoscopy during the waiting period between the initial diagnosis and IA should be considered in patients aged ≥ 40 years who may have malignant changes. Implementing IA as a first-line treatment will be beneficial to both patients and healthcare providers.

BACKGROUND/AIMS: Intestinal strictures represent an important serious complication of Crohn's disease. Shear wave elastography is a promising noninvasive ultrasound technique for assessing tissue stiffness. This study aimed to evaluate stiffness in the areas of intestinal stricture in patients with Crohn's disease using shear wave elastography and the changes in stiffness after biologics. MATERIALS AND METHODS: We enrolled 21 Crohn's disease patients having intestinal stricture. The patients consisted of 3 groups, which were the infliximab naïve (n = 6) group, the ustekinumab naïve (n = 8), and the bio-switch from infliximab to ustekinumab (n = 7) group. Bowell wall thickness was examined by ultrasound sonography, and the stiffness of Crohn's disease stricture lesions was evaluated using Shear wave speed before and 1 year after anti-tumor necrosis factor-alpha antibody infliximab, anti-interleukin 12/23 antibody ustekinumab, and bio-switch from infliximab to ustekinumab. RESULTS: Bowell wall thickness was significantly improved after infliximab, ustekinumab, and the bio-switch. However, shear wave speed indices only in the ustekinumab group significantly decreased after treatment (P = .028), but not in the other group. CONCLUSIONS: Shear wave elastography might be a useful method to evaluate stiffness in the areas of intestinal stricture in patients with Crohn's disease treated with biologics. However, a prospective randomized study evaluating the development of obstruction after biological treatment is needed to validate the study findings.

ß-D-glucan is extensively employed as a supplementary diagnostic tool for Pneumocystis pneumonia (PCP) and typically yields positive results in most cases. We present a case of a 73-year-old woman with a history of rheumatoid arthritis, who was receiving biological agents and was admitted due to pneumonia. Initially, the ß-D-glucan test was negative. However, as the disease progressed, it eventually turned positive, leading to the diagnosis of PCP. The patient was treated with corticosteroids and trimethoprim-sulfamethoxazole, resulting in pneumonia resolution. Our findings suggest that repeated assessment of ß-D-glucan levels holds diagnostic value in patients without human immunodeficiency virus infection.
