Efficacy of Integrated Online Mindfulness and Self-compassion Training for Adults With Atopic Dermatitis: A Randomized Clinical Trial.

Importance: Quality of life (QOL) of patients with atopic dermatitis (AD) is reported to be the lowest among skin diseases. To our knowledge, mindfulness and self-compassion training has not been evaluated for adults with AD. Objective: To evaluate the efficacy of mindfulness and self-compassion training in improving the QOL for adults with AD. Design, Setting, and Participants: This randomized clinical trial conducted from March 2019 through October 2022 included adults with AD whose Dermatology Life Quality Index (DLQI) score, a skin disease-specific QOL measure, was greater than 6 (corresponding to moderate or greater impairment). Participants were recruited from multiple outpatient institutes in Japan and through the study's social media outlets and website. Interventions: Participants were randomized 1:1 to receive eight 90-minute weekly group sessions of online mindfulness and self-compassion training or to a waiting list. Both groups were allowed to receive any dermatologic treatment except dupilumab. Main Outcomes and Measures: The primary outcome was the change in the DLQI score from baseline to week 13. Secondary outcomes included eczema severity, itch- and scratching-related visual analog scales, self-compassion and all of its subscales, mindfulness, psychological symptoms, and participants' adherence to dermatologist-advised treatments. Results: The study randomized 107 adults to the intervention group (n = 56) or the waiting list (n = 51). The overall participant mean (SD) age was 36.3 (10.5) years, 85 (79.4%) were women, and the mean (SD) AD duration was 26.6 (11.7) years. Among participants from the intervention group, 55 (98.2%) attended 6 or more of the 8 sessions, and 105 of all participants (98.1%) completed the assessment at 13 weeks. The intervention group demonstrated greater improvement in the DLQI score at 13 weeks (between-group difference estimate, -6.34; 95% CI, -8.27 to -4.41; P < .001). The standardized effect size (Cohen d) at 13 weeks was -1.06 (95% CI, -1.39 to -0.74). All secondary outcomes showed greater improvements in the intervention group than in the waiting list group. Conclusions and Relevance: In this randomized clinical trial of adults with AD, integrated online mindfulness and self-compassion training in addition to usual care resulted in greater improvement in skin disease-specific QOL and other patient-reported outcomes, including eczema severity. These findings suggest that mindfulness and self-compassion training is an effective treatment option for adults with AD. Trial Registration: https://umin.ac.jp/ctr Identifier: UMIN000036277.

The additional diagnostic impact of positron emission tomography-computed tomography for lymph node metastasis from colorectal cancer: A prospective lymph node level analysis.

BACKGROUND: We conducted a prospective study to determine the diagnostic performance of positron emission tomography-computed tomography (PET-CT) for lymph node metastasis in colorectal cancer patients. METHODS: We enrolled patients scheduled to receive curative surgery with lymph node dissection for colorectal adenocarcinoma who underwent contrast-enhanced abdominopelvic CT and PET-CT before surgery and who had primary lesions of cT2 or deeper. A radiologist determined the fluorodeoxyglucose uptake and the standardized uptake value (SUV) and metabolic volume (MV) to diagnose metastasis in cases with enlarged lymph nodes (≥7 mm long in minor diameter) on contrast-enhanced CT. Two gastrointestinal surgeons intraoperatively identified target lymph nodes to assess the association between images and pathological findings. The diagnostic performance (i.e., sensitivity, specificity, and positive and negative predictive values) for lymph node metastasis was determined using multilevel logistic modeling. RESULTS: A total of 205 colorectal cancer patients were enrolled from February 2018 to April 2020 and 194 patients were analyzed in this study. The sensitivity, specificity, and positive and negative predictive values of PET-CT were 15.3% (13.4%-17.5%), 100.0% (99.0%-100.0%), 100.0% (51.2%-100.0%), and 98.7% (98.5%-99.0%), respectively. CONCLUSION: PET-CT is a useful modality for determining the presence of metastasis in swollen lymph nodes on contrast-enhanced CT in colorectal cancer patients.

Clinicopathological features of sporadic MSI colorectal cancer and Lynch syndrome: a single-center retrospective cohort study.

BACKGROUND: The clinical and pathological features of sporadic microsatellite instability-high (MSI) colorectal cancer (CRC) are still unclear. The present study aimed to clarify the clinicopathological features of sporadic MSI CRC in comparison with those of Lynch syndrome (LS) exploratorily. METHODS: The present study was a single-center, retrospective cohort study. Sporadic MSI CRC was defined as MSI CRC with aberrant promoter hypermethylation of the MLH1 gene, while hereditary MSI CRC was defined colorectal cancer in patients with LS. RESULTS: In total, 2653 patients were enrolled; of these, 120 (4.5%) had MSI CRC, 98 had sporadic MSI CRC, and 22 had LS. Patients with sporadic MSI CRC were significantly older (p < 0.001) than those with LS and had a right-sided colonic tumor (p < 0.001) which was pathologically poorly differentiated or mucinous (p = 0.025). The overall survival rate was significantly lower in patients with stage I, II or III MSI CRC than in those with LS (p = 0.024). However, the recurrence-free survival rate did not differ significantly (p = 0.85). CONCLUSIONS: We concluded that patients with sporadic MSI are significantly older, tumors more likely to locate in the right-sided colon, pathologically poorly differentiated or mucinous, and worse overall survival than in those with LS.

Benefit of intensive chemotherapy for elderly patients aged 80 years or older with metastatic colorectal cancer: a state-wide multicenter cohort study.

BACKGROUND: It remains unclear whether intensive chemotherapy for Stage IV colorectal cancer (CRC) patients aged 80 years or older is beneficial prognostically. This study aimed to investigate the overall survival of Stage IV CRC patients aged ≥ 80 years receiving intensive chemotherapy. METHODS: The study design was a population-based, multicenter, historical cohort study. The extracted participants' data were consecutive patients diagnosed as Stage IV CRC between January 2008 and May 2015 in nine hospitals in Japan. Patients were classified into two groups according to age: aged group (≥ 80 years) and younger group (< 80 years old). Intensive chemotherapy was defined as at least two courses of doublet chemotherapy with oxaliplatin-or irinotecan-based regimens. The primary outcome was the adjusted hazard ratio (HR) of age ≥ 80 years in patients who undergoing intensive chemotherapy. RESULTS: During the study period, 1259 patients were treated for Stage IV CRC in the participating hospitals. In total, 231 patients (18.3%) were in the aged group, and 1028 (81.7%) were in the younger group, and 788 (62.6%) underwent intensive chemotherapy. The median overall survival for the aged and younger group patients was 21.0 months (interquartile range (IQR), 10.6-34.1 months) and 24.3 months (IQR 12.6-39.3 months), respectively. The adjusted HR of age ≥ 80 years was 1.29 (confidence intervals 0.84-2.00). CONCLUSION: Stage IV CRC patients aged 80 years or older receiving intensive chemotherapy had a similar prognosis to those aged < 80 years. Avoiding intensive chemotherapy for mCRC patients simply because they are ≥ 80 years old is not recommended.

Comparison of ethanol concentrations after drinking in patients who underwent total gastrectomy versus healthy controls.

BACKGROUND: The safety of drinking in patients who have undergone total gastrectomy for gastric cancer has not been established. We conducted a clinical trial to investigate the trend in alcohol absorption in actual patients. METHODS: Patients who received total gastrectomy with lymph-node dissection and Roux-en-Y reconstruction six or more months ago were enrolled. Participants drank 1 unit (20 g) of ethanol within 1 h starting at least 1 h after a meal. The blood alcohol concentration (BAC) was then estimated by a measurement of the breath alcohol concentration. The peak and trend in the BAC in patients was compared with that in healthy volunteers who were matched with patients for the alcohol-sensitive genotype. RESULTS: Ten patients and 10 healthy people were enrolled in the BAC evaluation. The peak BAC (%) was 0.158 in patients after total gastrectomy versus 0.110 in control (P < 0.001). The mean half-life of BAC was 58.0 min in the patient group and 94.0 min in the control group, although the mean time to complete drinking was significantly longer in the patient group than in the control group at 40.8 versus 21.9 min (P = 0.009). CONCLUSION: Drinking alcohol is likely to carry a risk of increasing the BAC in patients who have undergone total gastrectomy.

Ramped versus sniffing position for tracheal intubation: A systematic review and meta-analysis.

BACKGROUND: Whether the ramped or sniffing laryngoscopy position is better for tracheal intubation is unclear. This study aimed to determine the efficacy and safety of tracheal intubation in the ramped versus sniffing position. METHODS: We conducted a systematic review and meta-analysis of randomized clinical trials to compare the ramped position with the sniffing position for tracheal intubation. We searched the databases of Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Excerpta Medica Database (Embase), ClinicalTrials.gov, and World Health Organization Clinical Trials Registry Platform up to December 2018. We included randomized-controlled trials, trials of participants who required tracheal intubation in any setting, and that compared tracheal intubation in the ramped and the sniffing positions. Two authors independently screened the trials, extracted the data, and assessed the risk of bias. We conducted the meta-analysis using the random-effects model to calculate the pooled risk ratio with 95% confidence interval. RESULTS: Of the 2631 titles/abstracts screened, three studies (representing 513 patients) were included in the meta-analysis. The pooled risk ratio with 95% confidence interval (CI) of the sniffing versus the ramped position was as follows: a first successful attempt, 0.97 (95% CI, 0.86-1.09; I2 = 55%); laryngoscopy attempts ≤2, 1.08 (95% CI, 0.88-1.31; I2 = 93%); and good glottic view with Cormack-Lehane grade ≤ 2, 0.86 (95% CI, 0.69-1.07; I2 = 86%). CONCLUSIONS: This systematic review and meta-analysis indicated no favorable aspects of the ramped position as compared to the sniffing position. Thus, further research is warranted to identify which is better in tracheal intubation. TRIAL REGISTRATION: PROSPERO identifier, CRD42019116819.

The effects of intensive oral care before surgery for gastric cancer patients.

OBJECTIVES: Oral function management has been recognized as important strategy for preventing postoperative complications. In this historical cohort study, we focused on the patients who planed gastrectomy, and investigated the appropriate duration and frequency of preoperative oral care to prevent complications after surgery. METHODS: Patients who planed surgery for gastric cancer between 2012 and 2018 were enrolled. We defined intensive oral care (IOC) as initial intervention at least three weeks before surgery and follow-up intervention within a week before surgery. As the primary outcome, the incidence of postoperative infectious complications was compared between the IOC and non-intensive oral care groups. RESULTS: A total of 576 patients were enrolled, including 66 with IOC. The incidence of infectious complications was 2/66 (3.0%) in the IOC group and 64/510 (12.5%) in the non-intensive oral care group. After adjusting for confounding factors, patients with IOC exposure had a lower chance of developing postoperative infectious complications (odds ratio; 0.217, 0.051-0.927). CONCLUSIONS: Intensive oral care can help prevent postoperative infectious complications after gastrectomy. These findings suggest that appropriate preoperative oral care includes at least two interventions: three weeks or more before and within one week before surgery.

The bacterial association with oral cavity and intra-abdominal abscess after gastrectomy.

BACKGROUND: Perioperative oral management has been reported to be effective for preventing postoperative infectious complications. In addition, severe periodontal disease was identified as the significant risk factor for complications after gastrointestinal surgery. We investigated the bacteriological association between the periodontal pocket, stomach mucosa and drainage fluid to determine whether oral bacteria directly cause intra-abdominal infection after gastrectomy. METHODS: Patients who were scheduled to undergo surgery for gastric cancer were prospectively enrolled. We evaluated the similarity of bacterial strains in periodontal pocket, stomach mucosa and fluid from drainage tube. Gingival crevicular fluid and dental plaque were collected from the periodontal pocket and cultured to detect bacteria. Specimens from the resected stomach were collected and used for bacterial culturing. Drainage fluid from the abdominal cavity was also cultured. RESULTS: All of 52 patients were enrolled. In the periodontal pocket, α-Streptococcus spp., Neisseria sp., and Prevotella sp. were mainly detected. Bacterial cultures in the stomach mucosa were positive in 26 cases. In 20 cases (76.9%), the detected strains were the same as those in the periodontal pocket. Six patients had the postoperative intra-abdominal infection after gastrectomy, and the same bacterial strains was detected in both of drainage fluid and periodontal pocket in two patients with severe periodontal disease. CONCLUSIONS: We found the bacteriological association that same strain detected in periodontal pocket, stomach and in intra-abdominal drainage fluid after gastrectomy in patients with periodontal disease.

The long-term outcomes in adolescent and young adult patients with colorectal cancer -A multicenter large-scale cohort study.

Introduction: The prognosis of adolescent and young adult (AYA) patients with colorectal cancer (CRC) is still unclear. The aim of this study was to investigate the clinical features and prognosis in AYA patients compared with middle- aged patients. Methods: Participants were identified from a clinical database of the multicenter cohort in Japan. The AYA group was defined as those <40 years of age, whereas the middle-aged group was defined in 10-year ranges around the median age of all patients. The primary outcome was the overall survival (OS), and the secondary outcome was the recurrence-free survival (RFS). Results: A total of 502 patients were enrolled as the AYA group, and 7222 patients between 65 and 74 years of age were identified as the middle-aged group. The OS of colon cancer in stages II and III was significantly better in the AYA group (p = 0.033, 0.006, respectively) than in the middle-aged groups. There were no significant differences in the OS of rectal cancer in stages II and III between the two groups. Conclusion: The prognosis of AYA patients with CRC was the same or better than that in middle-aged patients.

Usefulness of a multibending endoscope in gastric endoscopic submucosal dissection.

BACKGROUND AND AIMS: Intraoperative perforation is a major adverse event of endoscopic submucosal dissection (ESD). To avoid perforation, it is important for the endoscope to approach the portion to be resected carefully and to ensure that the knife can approach the submucosa at an angle parallel to the muscle layer. The multibending endoscope has 2 bends at its tip and may facilitate the ESD procedure. To the best of our knowledge, very few studies have reported the use of the multibending endoscope during gastric ESD. The aim of this study was, therefore, to introduce the usefulness of the multibending endoscope for gastric ESD. METHODS: We report 2 cases of early gastric cancer in which ESD was performed using a multibending endoscope. RESULTS: Unlike conventional single-bending endoscopes that have only 1 moveable part, the multibending endoscope allowed difficult areas to be approached more easily. Small adjustments could be made to the upward or downward angle of both the first and the second bending sections of the endoscope. This ensured that the knife would approach the submucosa at an angle parallel to the muscle layer. In patient 1, initially the conventional endoscope was used, but it became more difficult to approach the site, and paradoxic movement occurred. When the conventional endoscope was changed to the multibending endoscope, the ESD procedure became safer and more efficient. Another ESD using the multibending endoscope was performed successfully without any adverse events. CONCLUSIONS: The use of a multibending endoscope for ESD will enable safer and faster treatment of patients.

Clinical impact of periodontal disease on postoperative complications in gastrointestinal cancer patients.

BACKGROUND: The effectiveness of perioperative oral management in gastrointestinal surgery remains unclear. To elucidate the clinical significance of oral care, we investigated the relationship between the oral environment and postoperative infectious complications (POICs) in patients undergoing gastrointestinal surgery. METHODS: This was a single-institute and historical cohort study of 341 patients. The participants were isolated from consecutive patients undergoing planned radical resection for gastrointestinal carcinoma from January 2016 to June 2017. Dentists assessed the oral environment for periodontal disease, hygiene status, dry mouth, fur on tongue, and tooth stumps. All patients received scaling and tooth brushing instructions. A stepwise logistic regression analysis was conducted to identify risk factors for POICs among the different oral statuses. RESULTS: The surgical procedures performed were gastrectomy in 123 (36.1%), colorectal resection in 185 (54.2%), and pancreatoduodenectomy or others in 38 (11.1%). POICs occurred in 48 patients (14.1%), including deep organ space infection in 20, surgical site infection in 11, anastomotic leakage in 5, urinary tract infection in 4, pneumonia in 2, and others in 6. After adjusting for confounding factors, periodontal disease was isolated as an independent risk factor for POICs (odds ratio 2.091, p = 0.037, 95% confidence interval 1.045-4.183). Other variables of oral environment such as hygiene status, dry mouth, fur on tongue, and tooth stumps did not have a significant impact on POICs. CONCLUSIONS: Periodontal disease is a risk factor for infectious complications after gastrointestinal surgery.

Microsatellite instability is inversely associated with type 2 diabetes mellitus in colorectal cancer.

BACKGROUND: Microsatellite instability (MSI) is a clonal change in the number of repeated DNA nucleotide units in microsatellites. High-frequency MSI (MSI-H) colorectal cancers (CRCs) are known to have different clinicopathological features compared with microsatellite stable (MSS) CRCs. In addition, previous studies have shown that type2 diabetes mellitus (T2DM) is a risk factor for malignant tumors including CRCs. The aim of this study was to investigate the relationship between T2DM and MSI-H colorectal cancer. METHODS: The study design is a single center, cross-sectional study. Data from a series of 936 patients with CRCs were collected and MSI status was assessed. RESULTS: In total, 29 (3.1%) and 907 (96.9%) tumors were classified as having MSI-H and low-frequency microsatellite instability or being MSS (MSS), respectively. Of the 936 patients, 275 (29.6%) were associated with T2DM. One (3.4%) of the 29 MSI-H patients and 274 (30.2%) of the 907 MSS patients had T2DM. Thus, the incidence of T2DM was significantly less frequent in MSI-H compared with MSS patients (Fisher's exact test: p = 0.0007). CONCLUSIONS: We conclude that MSS tumors are significantly more common than MSI-H tumors among individuals with T2DM.

[Four Patients Who Underwent Proton Beam Therapy after Debulking Surgery and Omental Wrapping of the Residual Tumor as a Spacer for Unresectable Local Recurrence of Rectal Cancer].

We report 4 patients who underwent proton beam therapy after debulking surgery for unresectable local recurrence of rectal cancer. Case 1: A 55-year-old man underwent radiotherapy and systemic chemotherapy for local recurrence; however, the lesion exhibited evident regrowth. Combination therapy of debulking surgery, omental wrapping of the residual tumor as a spacer, and postoperative proton beam therapy was performed. He died of lung metastasis after 24 months. Case 2: A 79- year-old woman who underwent surgical resections and radiotherapy twice in a previous hospital was referred to our hospital. Similar to that in case 1, proton beam therapy after debulking surgery and omental wrapping was performed. She died of lymph node metastasis after 31 months. Case 3: A 75-year-old man was diagnosed with unresectable local recurrence of rectal cancer. He underwent combination therapy and is doing well without any recurrence for 43 months. Case 4: A 57-yearold woman was also diagnosed with unresectable local recurrence. She underwent the same combination therapy after systemic chemotherapy. She died of lymph node metastasis after 11 months.

Underexpression of miR-126 and miR-20b in hereditary and nonhereditary colorectal tumors.

OBJECTIVES: The aim of the study was to determine the significance of miR-126 and miR-20b in colorectal carcinogenesis. METHODS: We analyzed the expressions of miR-126 and miR-20b in 136 colorectal tumors from 39 microsatellite stable (MSS) tumors, 23 high microsatellite instability (MSI-H) tumors, 16 Lynch syndrome, and 58 familial adenomatous polyposis (FAP) tumors including adenoma, intramucosal carcinoma, and invasive carcinoma. RESULTS: All four kinds of tumors showed underexpression of both miR-126 and miR-20b. The frequency of miR-126 downregulation was 100.0% in FAP adenomas, 85.7% in FAP intramucosal carcinomas, 78.9% in invasive carcinomas, 81.3% in Lynch syndrome tumors, 68.4% in MSS tumors, and 65.4% in MSI-H tumors. The frequency of miR-20b downregulation was 64.0% in FAP adenomas, 50.0% in FAP intramucosal carcinomas, 73.3% in invasive carcinomas, 62.5% in Lynch syndrome tumors, 79.5% in MSS tumors, and 91.3% in MSI-H tumors. The current study demonstrated underexpression of miR-126 and miR-20b in various types of colorectal cancer. These findings support the hypothesis that angiogenesis results from underexpressions of miR-126 and miR-20b and occurs as an early event in colorectal carcinogenesis. CONCLUSIONS: Underexpression of miR-126 and miR-20b was observed in various types of colorectal cancer, and occurs as an early event of colorectal carcinogenesis in FAP tumors.

Pulmonary and pleural metastases from benign meningeal meningioma: a case report.

Meningiomas are generally benign tumors, but rarely metastasize outside of the central nervous system. A 25-year-old female was admitted to our institute because of an abnormal shadow on her chest x-ray. A computed tomography (CT) scan showed a 3-cm, well- circumscribed mass in the right lower lobe of the lung. We performed thoracotomy and resected three pulmonary tumors at the right lung and diaphragm. Histological examination revealed a benign meningothelial meningioma. Six months later, she complained of heaviness of her head and a head CT scan revealed an intracranial mass. A craniotomy was performed and a brain tumor was found to be histologically identical to the lung tumors. During the 21 years since the first operation, we performed three times of pulmonary and pleural metastasectomies and two times of resection of intracranial local recurrences. All of those tumors were meningothelial meningioma without malignant change. The patient is alive without metastasis after the last resection of metastatic tumors.

[How does we treat liver metastases from colorectal cancer by cure-intent surgery ?].

Surgery is the most optimal and curative intent strategy for liver recurrence from colorectal cancer. There are scoring systems and grade classification for liver resection. If we carry out preoperative imaging of liver metastases strictly following to liver resection, we can expect to get a cure state satisfactory. Early detection and repeated liver resection improve the outcome of residual liver recurrence after liver resection. The maximum number of liver metastases for cure intent liver resection is unclear. Further examination is necessary.
