RESUMO
BACKGROUND: Patients with inflammatory bowel disease (IBD) experience difficulties in daily life and demanding self-care needs. The goal of our support for patients is to ease their difficulties and improve their belief in their capacity to self-manage their disease (self-efficacy), by increasing their ability for self-care. The nurse's contribution is vital in empowering patients and supporting them to better manage their disease. There is evidence that higher nurse staffing levels are associated with better patient outcomes in acute care settings, but little is known about the outpatient setting. The objective of this study was to explore the impact of multidisciplinary team care with abundant nurse staffing levels on patient-reported outcome measures (PROMs) among patients with IBD, encompassing Crohn's disease (CD) and ulcerative colitis (UC), in clinical remission. METHODS: Patients with IBD in clinical remission were included because disease activity influences the patient's subjective evaluation. A total of 499 valid responses from two different sources were analyzed: 318 from a specialized IBD clinic with abundant nurse staffing and a multidisciplinary care team (UC: 83, CD: 235) and 181 from an online survey panel (UC: 109, CD: 72). The IBD Self-Efficacy Scale (IBD-SES) and the difficulty of life scale (DLS) were used as disease-specific PROMs. RESULTS: In two multiple regression models adjusted by background characteristics (age, sex, diagnosis [UC/CD], employment status, use of biologics, and disease duration) using the IBD-SES or DLS as a dependent variable, the responses from clinic patients showed a more favorable score (higher self-efficacy or lower difficulty) than the online responses. CONCLUSIONS: Multidisciplinary team care with abundant nurse staffing may improve self-efficacy and ease difficulties of life among patients with IBD in clinical remission. These results could help bring attention to nurse staffing in an outpatient setting, which has previously been overlooked, and be the first to provide evidence of its importance in encouraging enhanced staffing levels.

Background: Responding to inpatient deterioration is less favorable at night than during the day, and this may be related to barriers in collaboration between physicians and nurses. However, there had been no way to assess the problem. This study aimed to develop a scale for physicians to measure difficulties in nighttime collaboration with nurses in response to deteriorating inpatients and to identify factors associated with the developed scale scores. Methods: We developed a draft scale of Nighttime Collaboration Difficulties between Nurses and Physicians for Physicians (NCDNP-P) based on key informant interviews with physicians. Psychometric validations, including structural validity, criterion-related validity, and reliability tests, were conducted among physicians who worked on night duty or on call in acute-care hospitals in Japan using a cross-sectional web-based questionnaire. Multiple linear regression analyses were performed using independent variables including individual backgrounds, style of working at night, and facility characteristics. Results: By performing exploratory factor analysis, we confirmed the structural validity of the NCDNP-P, consisting of seven items and two domains (Domain 1: Dissatisfaction with reporting, Domain 2: Barriers to working with nurses). Cronbach's alpha and McDonald's omega coefficients were 0.81-0.84 and 0.81-0.89, respectively. The criterion-related validity for interprofessional collaboration was confirmed. Multiple regression analysis revealed that the variables employment status, number of night shifts, frequency of nighttime calls about patients under another physician's charge, and handover between physicians before changing shifts were statistically significantly associated with NCDNP-P scores. Conclusion: We developed the NCDNP-P, confirming its reliability and validity. Identified factors reflect physicians' characteristics and the problems experienced working at night and may be associated with barriers in nighttime collaboration. The NCDNP-P can highlight issues in clinical settings and lead to the consideration of initiatives to address such issues.
RESUMO
Introduction: The incidence of steatotic liver disease has increased in recent years. Thus, steatotic liver disease is a major public health issue in Japan. This study investigated the association between weight reduction and the remission of metabolic dysfunction-associated steatotic liver disease (MASLD)/Metabolic and alcohol related/associated liver disease (MetALD) in Japanese individuals undergoing health checkups. Methods: This retrospective observational study included 8,707 Japanese patients with MASLD/MetALD who underwent health checkups from May 2015 to March 2023. The participants were monitored for its remission at their subsequent visit. MASLD was diagnosed on abdominal ultrasonography and based on the presence of at least one of five metabolic abnormalities. The impact of body mass index (BMI) reduction on MASLD/MetALD remission was assessed via logistic regression analysis and using receiver operating characteristic curves. Results: Logistic regression analysis revealed that weight loss was significantly associated with MASLD/MetALD remission. Other factors including exercise habits and reduced alcohol consumption were significant predictors of MASLD/MetALD remission in the overall cohort and in male patients. The optimal BMI reduction cutoff values for MASLD/MetALD remission were 0.9 kg/m2 and 4.0% decrease in the overall cohort, 0.85 kg/m2 and 3.9% decrease in males, and 1.2 kg/m2 and 4.5% decrease in females. In participants with a BMI of 23 kg/m2, the cutoff values were 0.75 kg/m2 and 2.7% BMI reduction. Discussion: Weight reduction plays an important role in both MASLD and MetALD remission among Japanese individuals. That is, targeting specific BMI reduction is effective. This underscores the importance of targeted weight management strategies in preventing and managing MASLD/MetALD in the Japanese population.

BACKGROUND: The inflammatory bowel disease self-efficacy scale (IBD-SES) is an instrument used across many countries to measure important health outcomes of patients with inflammatory bowel disease (IBD). We aimed to develop and validate a substantially shorter version of this scale to reduce patients' response burden. METHODS: A total of 919 patients with IBD, 482 recruited from an IBD clinic and 437 recruited online, completed the Japanese version of the original, 29-item IBD-SES. These data were then used to develop a shorter version of the scale. The original 29 items of the IBD-SES were reduced with three analytic steps: assessing ceiling and floor effect, testing correlation between items, and assessing test-retest reliability. The resulting 13-item IBD-SES was evaluated for construct validity by confirmatory factor analysis, criterion validity by Pearson correlation coefficients with original version, and internal consistency by item-total correlations and the Cronbach's α coefficient. RESULTS: The short version consisted of the same four subscales "managing stress and emotions," "managing medical care," "managing symptoms and disease," and "maintaining remission" as the original scale. The fit indices of the final model were as follows: normed chi-square, 7.18 (p < 0.001); comparative fit index, 0.94; goodness-of-fit index, 0.93; adjusted goodness-of-fit index, 0.89; parsimony goodness-of-fit index, 0.60; and root mean square error of approximation, 0.084. Correlation of each subscale with the original scale was high (0.97-0.98). Cronbach's α for each subscale ranged from 0.68 to 0.86. CONCLUSIONS: A short version of the IBD-SES was developed. The results confirmed the improved validity, reliability, and psychometric properties of the IBD-SES. TRIAL REGISTRATION: Not applicable.

BACKGROUND: The Bristow coracoid transfer procedure is a reliable technique for treating anterior shoulder instability in patients with large glenoid bone loss or those involved in collision sports. However, its success is marred by its inferior bone union rate of the coracoid process as compared to the Latarjet procedure. This study aimed to evaluate whether arthroscopic confirmation of the secured coracoid fixation during the Bristow procedure improves the bone union rate and clinical outcomes as compared to the open procedure. METHODS: We retrospectively reviewed 104 rugby players (n = 111 shoulders) who underwent an open (n = 66 shoulders) or arthroscopy (AS)-assisted (n = 45 shoulders) Bristow procedure at our center from 2007 to April 2019. In the AS-assisted group, the screw fixation and coracoid stability and contact were confirmed under arthroscopic visualization. Graft union was evaluated through computed tomography at 3 months, 6 months, and 1 year postoperatively. Patient-reported outcome measures were assessed based on the American Shoulder and Elbow Surgeons score, Rowe score, and satisfaction rate. Recurrence, the rate of return to play (RTP), and the frequency of pain after RTP were also assessed. RESULTS: The mean follow-up period was 73.5 (range: 45-160) months for the open group and 32.3 (range: 24-56) months for the AS-assisted group. In the former, the rates of bone union were 50%, 72.7%, and 88.9% at 3 months, 6 months, and 1 year, respectively. In contrast, the AS-assisted group had significantly greater bone union rates-88.9%, 93.3%, and 95.6% at 3 months, 6 months, and 1 year, respectively. Both groups showed significant improvement in the American Shoulder and Elbow Surgeons and Rowe scores compared to preoperative values as well as high satisfaction rates (open: 92%; AS-assisted: 95.7%). There were no statistically significant differences in the recurrence and RTP rates as well as the frequency of pain after RTP between the 2 groups. CONCLUSION: The AS-assisted procedure allows early and high bone healing without compromising the clinical outcomes.
RESUMO
OBJECTIVES: Interventions for patients with death rattle remain under consideration, and their families strongly acknowledge the need for improved care. However, few reports exist concerning specific and comprehensive nursing practices for them. This study aimed to clarify nursing practices for patients with death rattle and their families in hospital wards and examine each practice's importance. METHODS: We used a modified Delphi method with expert nurses with extensive experience in end-of-life care. Participants were recruited using convenience and snowball sampling. First, we developed a list of nursing practices through a literature review and individual interviews. Second, we conducted the Delphi survey. Two rounds of judging were performed. Items were rated on a 9-point Likert scale (1=not important at all to 9=very important). An item was considered 'important' if at least 80% of the participants rated it ≥7. RESULTS: The list comprised 40 items across 8 domains: assessment of death rattle and the distress felt by the patients, oral care, repositioning, adjustment of parenteral hydration, suctioning, administration of alleviating medications, communication with and assessment of family members who witness death rattle, and nurse's attitude towards death rattle and the relevant interventions. Of the 46 recruited experts, 42 participated in both rounds. Participants regarded 37 of the 40 items as important. CONCLUSIONS: This study specifically and comprehensively identified nursing practices for patients with death rattle and their families using a modified Delphi method to support clinical nursing practice and improve the quality of care.
RESUMO
Introduction: Dietary temperance significantly affects the quality of life of patients with Crohn's disease (CD) and remains a major concern. However, perceptions of diet in remission may have changed from the era when treatment options were limited. Therefore, we compared the dietary perceptions and treatment of patients with CD in remission with previously published data from the time biologic therapy was not introduced. Methods: We compared the data of 254 patients with CD in remission who completed a questionnaire survey in 2022 with those of 76 patients with CD in remission collected in 2003, when biologics were not used for maintenance therapy in Japan. Remission was defined as a CD activity index of 150 or less in both studies. Perceptions of diet (degree of eating whatever one likes) were assessed using single-item nominal scale responses. Results: The percentage of patients receiving enteral nutrition therapy had decreased (past vs. present: 43.4 vs. 12.6%), while the proportion of patients receiving biologic therapy increased (0 vs. 88.6%, respectively). The percentages of patients who responded "not at all," "sometimes," and "mostly" when asked if they could eat whatever they liked had changed, respectively, from 9.2%, 46.1%, and 44.7% in the past to 4.3%, 25.2%, and 70.5% in the present. Conclusion: The proportion of those who ate whatever they liked and the mean body mass index increased in comparison with the corresponding values 20 years ago. With the advent of biologic therapies, the number of patients with CD who can enjoy eating has increased.
RESUMO
A 70-year-old man was admitted to our hospital for the treatment of a large granular-type laterally spreading tumor in the splenic flexure of the descending colon. The preoperative diagnosis was intramucosal colon carcinoma and endoscopic submucosal dissection was performed. During treatment, a small perforation occurred accidentally. After conservative treatment with endoscopic suturing, the patient was discharged without additional surgery. The pathological diagnosis was an intramucosal carcinoma. One year after treatment, no local recurrence was observed on endoscopy, and abdominal computed tomography showed no obvious metastasis. Two years later, fluorodeoxyglucose-positron emission tomography/computed tomography, laparoscopic findings, and histopathologic findings by experimental excision of omentum revealed several disseminated peritoneal metastases from previously treated colon carcinoma. To the best of our knowledge, this is the first report of peritoneal dissemination after a small perforation during endoscopic submucosal dissection and conservative therapy for early-stage colon carcinoma. This report suggests the possibility of tumor dissemination in patients with small perforations during endoscopic procedures. Endoscopists should be aware of these rare potential risks and perform later surveillance carefully.

OBJECTIVES: Laparoscopic adrenalectomy has been the gold standard surgical procedure. However, the adaptation criteria for malignant tumors and predictors of perioperative outcomes are not well defined. Therefore, this study tried to identify valid predictors for perioperative outcomes of laparoscopic adrenalectomy and consider the adaptation criteria. METHODS: We retrospectively reviewed the preoperative and perioperative data of 216 patients who underwent transperitoneal laparoscopic adrenalectomy in our hospital. Preoperative factors associated with perioperative outcomes were analyzed using multiple regression analysis. RESULTS: Among 216 patients, 165 (76.4%), 26 (12.0%), and 25 (11.6%) were suspected of having benign tumors, pheochromocytoma, and malignant tumors, respectively. Median tumor size was 25.0 mm (interquartile range 18.0-35.0); median perirenal fat thickness was 9.2 mm (interquartile range 4.9-15.6) on preoperative computed tomography scans. The median operative time was 145.5 min (interquartile range 117.5-184.0) and the median estimated blood loss was 0.0 mL (interquartile range 0.0-27.3). Perirenal fat thickness (p < 0.001), tumor size (p < 0.001), and malignant tumors (p = 0.020) were associated with operative time, and perirenal fat thickness (p = 0.038) and malignant tumors (p = 0.002) were associated with estimated blood loss. CONCLUSIONS: Perirenal fat thickness, tumor size, and malignant tumors are valid predictors of the surgical outcomes of transperitoneal laparoscopic adrenalectomy. As only perirenal fat thickness is associated with both surgical outcomes except for malignant tumors, it is a powerful predictor. Transperitoneal laparoscopic adrenalectomy for large malignant adrenal tumors with thick perirenal fat should be performed with caution.

BACKGROUND: Heart failure (HF) patients have high readmission rates and require continuous adherence to HF self-care. Lack of knowledge about HF has been identified as a factor that contributes to poor adherence. OBJECTIVES: To clarify and organise existing data about measurement tools used to assess pre-discharge knowledge of hospitalised HF patients, the content and level of pre-discharge knowledge, factors associated with the level of knowledge, and the effect of knowledge levels on patients' outcomes. METHODS: Four electronic databases were searched for articles that described the content and level of knowledge of pre-discharge HF patients. RESULTS: Thirty-three studies were included in this review. Twenty-two measurement tools were identified used for pre-discharge knowledge assessment. 'Heart failure pathophysiology and treatment' and 'salt and fluid management' were the most common knowledge content measured. The level of knowledge of 'the nature, definition, and causes of symptoms of heart failure' and 'fluid and medication management' tended to be low. High levels of knowledge were found for 'higher educational background', 'previous heart failure hospitalisation', and 'previous heart failure education', while low levels were found for: 'high number of medications' and 'first heart failure hospitalisation'. The level of HF knowledge implies an impact on compliance and self-care. CONCLUSION: HF patients have low level of knowledge of the nature and causes of HF and fluid management prior to hospital discharge. Some of the variables that influenced the level of patient knowledge were educational background, number of medications taken, and disease duration.

BACKGROUND: Although detection and response to clinical deterioration have been studied, the range and nature of studies focused on night-time clinical setting remain unclear. AIM: This study aimed to identify and map existing research and findings concerning night-time detection and response to deteriorating inpatients in usual care or research settings. STUDY DESIGN: A scoping review method was used. PubMed, CINAHL, Web of Science, and Ichushi-Web databases were systematically searched. We included studies focusing on night-time detection and response to clinical deterioration. RESULTS: Twenty-eight studies were included. These studies were organized into five categories: night-time medical emergency team or rapid response team (MET/RRT) response, night-time observation using the early warning score (EWS), available resources for physicians' practice, continuous monitoring of specific parameters, and screening for night-time clinical deterioration. The first three categories were related to interventional measures in usual care settings, and relevant findings mainly demonstrated the actual situation and challenges of night-time practice. The final two categories were related to the interventions in the research settings and included innovative interventions to identify at-risk or deteriorating patients. CONCLUSIONS: Systematic interventional measures, such as MET/RRT and EWS, could have been sub-optimally performed at night. Innovations in monitoring technologies or implementation of predictive models could be helpful in improving the detection of night-time deterioration. RELEVANCE TO CLINICAL PRACTICE: This review provides a compilation of current evidence regarding night-time practice concerning patient deterioration. However, a lack of understanding exists on specific and effective practices regarding timely action for deteriorating patients at night.

BACKGROUND: Postoperative delirium (POD) is a complication after surgery which leads to worse outcomes. The frequency of this syndrome is increasing as more elderly patients undergo major surgery. The frequency is around 10-25% but reaches as high as 50% for cardiac surgery. Although intranasal insulin (INI) administration of up to 160 units in patients with cognitive dysfunction and delirium has been shown to improve memory function and brain metabolism without complications such as hypoglycemia, it remains unknown whether INI prevents POD after cardiac surgery METHODS: A multicenter, double-blind, randomized, controlled trial will be conducted at University of Tsukuba Hospital and Tsukuba Medical Center Hospital, Japan, from July 1, 2023, to December 31, 2025. A total of 110 elderly patients (65 years old or older) undergoing cardiac surgery requiring cardiopulmonary bypass will be enrolled and randomly allocated to intranasal insulin or intranasal saline groups. The primary outcome is the incidence of POD within 7 days after surgery. Secondary outcomes include days and times of delirium, screening tests of cognitive function, pain scores, duration of postoperative tracheal intubation, and length of ICU stay. DISCUSSION: The present objective is to assess whether 80 IU INI administration during surgery prevents POD after cardiac surgery. The results may provide strategic choices to prevent POD in patients with cardiac surgery requiring cardiopulmonary bypass. TRIAL REGISTRATION: The trial was registered with the Japan Registry for Clinical Trials with identifier jRCTs031230047 on April 21, 2023.

BACKGROUND: Prevalence trends and reasons for pediatric surgery cancellation in Japan during the coronavirus disease 2019 (COVID-19) pandemic have not previously been reported. This study aimed to compare the prevalence and reasons for cancellation of pediatric surgeries in Japan before and during the COVID-19 pandemic. METHODS: This single-center retrospective cohort study reviewed the reasons for surgery cancellations scheduled for patients aged <18 years between the prepandemic period (September 2017-December 2019) and the COVID-19 pandemic period (January 2020-April 2022). The cancellation reasons were classified into four major categories: medical, surgical, patient-related, and administrative. RESULTS: Of the 3395 and 3455 surgeries scheduled before and during the COVID-19 pandemic, 305 (9.0%) and 319 (9.2%) surgeries were canceled (p = 0.737), respectively. The proportion of cancellations due to infections or fever in medical reasons decreased from 67.9% to 56.1% (p = 0.003) and that due to patient-related reasons increased from 6.6% to 15.1% (p = 0.001). Further, the proportion of cancellations due to staff shortages in staff administrative reasons increased from 0.3% to 3.1% (p = 0.011). There was no significant difference in the proportion of surgeries canceled due to surgical reasons between the two periods. CONCLUSIONS: The proportion of cancellations due to infections or fever decreased during the COVID-19 pandemic, while that due to staff shortages increased. Infection prevention is an important measure to address the staff shortages. Implementation of national or regional policies and additional strategic interventions may be required to prepare for disasters like the COVID-19 pandemic.

Introduction: The effectiveness of nivolumab plus cabozantinib for metastatic papillary renal cell carcinoma with inferior vena cava tumor thrombus remains unclear. Case presentation: A 77-year-old male was diagnosed with right papillary renal cell carcinoma with a metastatic lesion on Gerota's fascia, lymph node metastasis, and inferior vena cava tumor thrombus. He was treated with nivolumab plus cabozantinib. As all lesions regressed enough to permit complete resection, radical nephrectomy, thrombectomy, and retroperitoneal lymph node dissection were performed. No viable malignant cells were identified histopathologically. Despite the discontinuation of nivolumab plus cabozantinib, there has been no recurrence for 9 months. Conclusion: Nivolumab plus cabozantinib has effectiveness for metastatic papillary renal cell carcinoma with inferior vena cava tumor thrombus.
RESUMO
We report a case of a 54-year-old man with atrial septal defect who presented with oxygen desaturation on pulse oximetry. Cardiac magnetic resonance imaging and transesophageal echocardiography showed right-to-left shunting through an atrial septal defect, which was confirmed by superior vena cavography and suggested Eisenmenger syndrome. However, cardiac catheterization revealed a normal pulmonary arterial pressure. Simultaneous measurement of interatrial pressure identified two transient interatrial pressure gradient points, where the right atrial pressure was higher than the left atrial pressure. The patient was finally diagnosed with atrial septal defect without pulmonary hypertension. Right-to-left shunting was primarily caused by a transient interatrial pressure gradient due to a time delay in both initial atrial contraction and completion of passive ventricular filling between the right and left sides of the heart. Surgical closure of the atrial septal defect was performed, and hypoxemia improved. This is the first report of right-to-left shunting without pulmonary hypertension caused by a transient interatrial pressure gradient due to a time delay between the right and left cardiac cycles. Precise assessment of the simultaneous interatrial pressure in addition to diagnostic imaging played a pivotal role in clarifying the etiology of this rare condition. Learning objective: Atrial septal defect with right-to-left shunting without Eisenmenger syndrome is a rare condition. We identified transient interatrial pressure gradients associated with a time delay in both initial atrial contraction and completion of the passive ventricular filling phase, which we considered as the primary mechanism underpinning right-to-left shunting. Simultaneous measurement of interatrial pressure played a pivotal role in elucidating the hemodynamics and abnormal shunt flow mechanism.
RESUMO
Introduction: Although the efficacy of 5-aminosalicylic acid (ASA) suppositories for ulcerative colitis (UC) has been reported in many studies, many studies have also described poor adherence to 5-ASA suppository regimens. We aimed to identify the clinical background factors that influence adherence to 5-ASA suppositories to improve adherence and efficacy of the treatment. Methods: We conducted a retrospective cohort study of 61 patients with active UC who were using 5-ASA suppositories. All patients underwent endoscopy and rectal biopsy for histological diagnosis prior to 5-ASA suppository treatment. The efficacy of 5-ASA suppository treatment was compared in relation to clinical background factors (sex, age, disease duration, disease type, clinical activity, Ulcerative Colitis Endoscopic Index of Severity, histological activity, serum C-reactive protein level, concomitant use of immunomodulators, history of steroid use, and dose of oral 5-ASA). Results: The efficacy of 5-ASA suppositories was significantly related to low Lichtiger Colitis Activity Index (LCAI) scores and proctitis type prior to its use. In terms of sex, females tended to show higher efficacy. Multivariate logistic regression analysis using these three factors showed high predictive value for the efficacy of 5-ASA suppositories (AUC, 0.788; sensitivity, 87.2%; and specificity, 63.7%). Conclusion: This study is the first to extract clinical background factors for predicting the efficacy of 5-ASA suppositories. The use of 5-ASA suppositories in patients who are expected to show efficacy will be effective in improving patient co-operation.
