RESUMO
BACKGROUND: Intensive care units (ICUs) have mortality rates of 10%-29% owing to illness severity. Postintensive care syndrome-family affects bereaved relatives, with a prevalence of 26% at 3 months after bereavement, increasing the risk for anxiety and depression. Complicated grief highlights issues such as family presence at death, inadequate physician communication and urgent improvement needs in end-of-life care. However, no study has comprehensively reviewed strategies and components of interventions to improve end-of-life care in ICUs. AIM: This scoping review aimed to analyse studies on improvement of the quality of dying and death in ICUs and identify interventions and their evaluation measures and effects on patients. METHODS: MEDLINE, CINAHL, PsycINFO and Central Journal of Medicine databases were searched for relevant studies published until December 2023, and their characteristics and details were extracted and categorised based on the Joanna Briggs model. RESULTS: A total of 24 articles were analysed and 10 intervention strategies were identified: communication skills, brochure/leaflet/pamphlet, symptom management, intervention by an expert team, surrogate decision-making, family meeting/conference, family participation in bedside rounds, psychosocial assessment and support for family members, bereavement care and feedback on end-on-life care for healthcare workers. Some studies included alternative assessment by family members and none used patient assessment of the intervention effects. CONCLUSION: This review identified 10 intervention strategies to improve the quality of dying and death in ICUs. Many studies aimed to enhance the quality by evaluating the outcomes through proxy assessments. Future studies should directly assess the quality of dying process, including symptom evaluation of the patients.
RESUMO
BACKGROUND: Although accurate preoperative diagnosis of lymph node metastasis is essential for optimizing treatment strategies for low rectal cancer, the accuracy of present diagnostic modalities has room for improvement. OBJECTIVE: The study aimed to establish a high-precision diagnostic method for lymph node metastasis of low rectal cancer using artificial intelligence. DESIGN: A retrospective observational study. SETTINGS: A single cancer center and a college of engineering in Japan. PATIENTS: Patients with low rectal adenocarcinoma who underwent proctectomy, bilateral lateral pelvic lymph node dissection, and contrast-enhanced multidetector row CT (slice ≤1 mm) between July 2015 and August 2021 were included in the present study. All pelvic lymph nodes from the aortic bifurcation to the upper edge of the anal canal were extracted, regardless of whether within or beyond the total mesenteric excision area, and pathological diagnoses were annotated for training and validation. MAIN OUTCOME MEASURES: Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy. RESULTS: A total of 596 pathologically negative nodes and 43 positive nodes from 52 patients were extracted and annotated. Four diagnostic methods, with and without using super-resolution images and with and without using 3-dimensional shape data, were performed and compared. The super-resolution + 3-dimensional shape data method had the best diagnostic ability for the combination of sensitivity, negative predictive value, and accuracy (0.964, 0.966, and 0.968, respectively), whereas the super-resolution only method had the best diagnostic ability for the combination of specificity and positive predictive value (0.994 and 0.993, respectively). LIMITATIONS: Small number of patients at a single center and the lack of external validation. CONCLUSIONS: Our results enlightened the potential of artificial intelligence for the method to become another game changer in the diagnosis and treatment of low rectal cancer. See Video Abstract .

PURPOSE: Post-treatment detection of circulating tumor DNA (ctDNA) is strongly predictive of recurrence. Most molecular residual disease (MRD) assays require prior tissue testing to guide ctDNA analysis, resulting in lengthy time to initial results and unevaluable patients. PATIENTS AND METHODS: We assessed a tissue-free assay (Guardant Reveal) that bioinformatically evaluates >20,000 epigenomic regions for ctDNA detection in 1,977 longitudinally collected post-operative plasma samples from 342 patients with resected colorectal cancer (CRC). RESULTS: We observed sensitive and specific detection of MRD associated with clinically meaningful differences in recurrence-free interval at each timepoint evaluated with a median lead time of 5.3 months. Longitudinal sensitivity in stage II or higher colon cancer was 81%. Sensitivity increased with serial measurement and varied by recurrence site: higher for liver (100%) versus lung (53%) and peritoneal (40%). Sensitivity among rectal cancer patients was 60% owing to a high proportion of lung metastases. Specificity was 98.2% among 1,461 post-treatment samples (99.1% among those with follow-up longer than the upper interquartile range of the lead time observed in this study). CONCLUSIONS: Our data demonstrate the potential clinical utility of ctDNA as a tool to improve management of stage II and higher CRC with a methodology that is non-invasive, accessible, and allows for rapid evaluation to inform clinical decisions.

RESUMO
PURPOSE: Delay in initiating adjuvant chemotherapy (AC) after curative resection of colorectal cancer (CRC) has been reported to lead to poor prognosis, but few studies have looked at associated factors. This study aimed to identify risk factors for delay in initiating AC. METHODS: Data from 200 consecutive patients who underwent curative resection and AC for stage III CRC between 2013 and 2018 were retrospectively collected and analyzed. RESULTS: AC was initiated more than 8 weeks after surgery in 12.5% of patients (the delay group). Compared to those with no delay (the non-delay group), patients in the delay group had significantly higher rates of synchronous double cancers (2.3% vs. 16.0%, p = 0.001), preoperative bowel obstruction (10.3% vs. 32.0%, p = 0.003), laparotomy (56.0% vs. 80.0%, p = 0.02), concomitant resection (2.9% vs. 24.0%, p < 0.001), and postoperative complications (32.0% vs. 56.0%, p = 0.02), and a significantly longer length of hospital stay (median 12 vs. 30 days, p < 0.001). In multivariate analysis, synchronous double cancers (odds ratio 10.2, p = 0.008), preoperative bowel obstruction (odds ratio 4.6, p = 0.01), concomitant resection (odds ratio 5.2, p = 0.03), and postoperative complications of Clavien-Dindo grade ≥ IIIa (odds ratio 4.0, p = 0.03) were identified as independent risk factors for delay in initiating AC. CONCLUSION: Careful preoperative treatment planning for CRC patients with synchronous double cancers, preoperative bowel obstruction, and concomitant resection, and management for postoperative complication are necessary to avoid delay in initiating AC.

BACKGROUND/AIM: Complete surgical resection with negative margins remains the cornerstone for curative treatment of rectal cancer; however, local recurrence can pose a significant challenge. Herein, we aimed to introduce a novel surgical technique for combined resection of the pubic arch and ischial bone in the context of treating recurrent rectal cancer. CASE REPORT: We present a case of a patient with a fourth local recurrence of rectal cancer, with no evidence of distant metastasis. The tumor directly invaded the posterior wall of the pubic arch. To achieve complete tumor resection, an osteotomy was performed using a thread wire saw at the bilateral pubic rami and ischial bones. Intraoperative frozen section analysis (rapid tissue examination) was conducted on tissue samples from the lateral margins of the planned osteotomy line. Samples were negative for adenocarcinoma (cancerous cells). The combined resection of the pubic arch and ischial bone was successfully performed with negative margins for adenocarcinoma, as confirmed by frozen section analysis. CONCLUSION: Mastery of the surgical technique for combined resection of the pubic arch and ischial bone may be clinically significant for achieving complete resection in cases of multiple resections for locally recurrent rectal cancer.

Intensive care units (ICUs) are designed for critically ill patients who often experience high mortality rates owing to the severity of their conditions. Although the primary goal is patient recovery, it is crucial to understand the quality of death in the ICU setting. Nevertheless, there is a notable lack of systematic reviews on measured death quality and its associated factors. This study aims to conduct a quantitative synthesis of evidence regarding the quality of death in the ICU and offers a comprehensive overview of the factors influencing this quality, including its relationship with the post-intensive care syndrome-family (PICS-F). A thorough search without any language restrictions across MEDLINE, CINAHL, PsycINFO, and Igaku Chuo Zasshi databases identified relevant studies published until September 2023. We aggregated the results regarding the quality of death care for patients who died in the ICU across each measurement tool and calculated the point estimates and 95% confidence intervals. The quantitative synthesis encompassed 19 studies, wherein the Quality of Dying and Death-single item (QODD-1) was reported in 13 instances (Point estimate: 7.0, 95% CI: 6.93-7.06). Patient demographic data, including age and gender, as well as the presence or absence of invasive procedures, such as life support devices and cardiopulmonary resuscitation, along with the management of pain and physical symptoms, were found to be associated with a high quality of death. Only one study reported an association between quality of death and PICS-F scores; however, no significant association was identified. The QODD-1 scale emerged as a frequently referenced and valuable metric for evaluating the quality of death in the ICU, and factors associated with the quality of ICU death were identified. However, research gaps persist, particularly regarding the variations in the quality of ICU deaths based on cultural backgrounds and healthcare systems. This review contributes to a better understanding of the quality of death in the ICU and emphasises the need for comprehensive research in this critical healthcare domain.
RESUMO
Dysphagia or swallowing dysfunction is common in patients with acute or critical illness, and diverse methods of dysphagia rehabilitation are provided worldwide. We aimed to examine the efficacy of rehabilitation to treat dysphagia in patients with acute or critical illness. We searched PubMed, ICHUSHI, and Cochrane Central Register of Controlled Trials databases from inception to November 22, 2023 for relevant randomized controlled trials. We focused on dysphagic patients with acute or critical illness who were not orotracheally intubated. Our target intervention included conventional rehabilitation and nerve stimulation/neuromodulation techniques as dysphagia rehabilitation. Comparators were conventional or standard care or no dysphagia interventions. Primary outcomes included mortality, incidence of pneumonia during the study period, and health-related quality of life (HRQoL) scores within 90 days of hospital discharge. We pooled the data using a random-effects model, and classified the certainty of evidence based on the Grading of Recommendations, Assessment, Development, and Evaluation system. Nineteen randomized controlled trials involving 1,096 participants were included. Dysphagia rehabilitation was associated with a reduced incidence of pneumonia (risk ratio [RR], 0.66; 95% confidence interval [CI], 0.54-0.81; moderate certainty), but not with reduced mortality (RR, 0.92; 95% CI, 0.61-1.39; very low certainty) or improved HRQoL scores (mean difference, -0.20; 95% CI, -20.34 to 19.94; very low certainty). Based on the available moderate- or very low- quality evidence, while dysphagia rehabilitation had no impact on mortality or HRQoL, they might reduce the incidence of pneumonia in dysphagic patients with acute or critical illness.
RESUMO
Although phase III randomized controlled trials (RCTs) represent the most robust statistical approach for answering clinical questions, they require massive expenditures in terms of time, labor, and funding. Ancillary and supplementary analyses using RCTs are sometimes conducted as alternative approaches to answering clinical questions, but the available integrated databases of RCTs are limited. In this background, the Colorectal Cancer Study Group (CCSG) of the Japan Clinical Oncology Group (JCOG) established a database of ancillary studies integrating four phase III RCTs (JCOG0212, JCOG0404, JCOG0910 and JCOG1006) conducted by the CCSG to investigate specific clinicopathological factors in pStage II/III colorectal cancer (JCOG2310A). This database will be updated by adding another clinical trial data and accelerating several analyses that are clinically relevant in the management of localized colorectal cancer. This study describes the details of this database and planned and ongoing analyses as an initiative of JCOG cOlorectal Young investigators (JOY).

BACKGROUND: This study aimed to describe the surgical procedures involved in laparoscopic rectal resection in patients with obesity and report the short-term outcomes. MATERIALS AND METHODS: A total of 194 consecutive patients who underwent laparoscopic rectal resection in our department from 2013 to 2018 were divided into non-obese(body mass index[BMI] <25 kg/m2; n=161)and obese groups(BMI≥25 kg/m2; n=33)and subsequently analyzed. RESULTS: The operative time was significantly longer in the obese group(225 vs 266 min; p=0.003)than in the non-obese group. No conversions to laparotomy occurred in either group, and no discernible differences in blood loss(1 vs 5 mL; p=0.582), number of harvested lymph nodes(20 vs 17; p=0.356), and postoperative complication rates(9.3 vs 6.1%; p=0.547)were observed. CONCLUSION: Establishing an appropriate operative field, clarifying landmarks, and standardizing the procedure are important to assure safe laparoscopic rectal resection with adequate lymph node dissection in patients with obesity.

Deleterious germline variants in the BRCA1-associated ring domain (BARD1) gene moderately elevate breast cancer risk; however, their potential association with other neoplasms remains unclear. Here, we present the case of a 43-year-old female patient diagnosed with sigmoid colon adenocarcinoma whose maternal family members met the Amsterdam Criteria II for Lynch syndrome. Comprehensive multigene panel testing revealed a heterozygous BARD1 exon 3 deletion.
RESUMO
BACKGROUND: Currently, little evidence supports the notion that improved practical skills through simulation education are reflected in actual clinical practice and ultimately lead to positive outcomes for participants. However, by clarifying the relationship between the simulation foundation and its practicality, insights can be gained to develop educational programs to improve clinical reasoning skills. However, no clear scale is currently available in Japan. AIMS: To create a valid Japanese version of the clinical reasoning skills self-evaluation scale and evaluate its reliability and validity. METHODS: This instrument design study included 580 nursing students and nurses surveyed online from February to March 2023. The clinical reasoning skills self-evaluation scale was translated into Japanese using a back-translation method, and semantic equivalence and content validity were assessed. The content validity index was assessed using a pilot test involving 26 clinical nurses, 25 nursing students, and an expert panel. Validity and reliability were tested using a convenience sample of 580 nursing students and nurses. Reliability was assessed using internal consistency and test-retest reliability. Construct validity was assessed using confirmatory factor analysis. RESULTS: Cronbach's alpha for all dimensions was >0.7, and the questionnaire showed acceptable internal consistency. Test-retest reliability was evaluated using the intraclass correlation coefficient (0.674-0.797, all dimensions); the lowest value at a 95% confidence interval was 0.504 (at least moderate reliability). CONCLUSION: Our scale has acceptable validity and reliability. It may help in clinical reasoning skill assessment for nurses and nursing students and aid in examining and supporting these skills.
RESUMO
BACKGROUND/AIM: Stoma prolapse is a common complication in the late phase after stoma creation. With advances in chemotherapy, a double-orifice colostomy or ileostomy and chemotherapy are used to treat primary unresectable colorectal cancer. Preoperative therapy with a double-orifice colostomy or ileostomy is performed to aid primary colorectal cancer miniaturization. Therefore, the number of stoma prolapses will likely increase in the future. Previous reports on the repair of stoma prolapse focused on unilateral stoma prolapse of loop colostomy, and there are no reports about the bilateral stoma prolapse of loop colostomy or ileostomy. CASE REPORT: We report a novel repair technique for oral and anal side (bilateral) stoma prolapse of a loop colostomy with the stapled modified Altemeier method using indocyanine green (ICG) fluorescence imaging considering the distribution of marginal artery in preventing marginal artery injury which has considerable clinical significance. CONCLUSION: Our novel technique for the oral and anal side prolapse of a loop colostomy is considered effective and safe.

BACKGROUND: Sensory impairment affects the quality of life after intensive care. However, no studies have comprehensively examined sensory impairment after intensive care. OBJECTIVES: This study aimed to investigate sensory impairment in critically ill patients. METHODS: This ambidirectional cohort study was conducted in the intensive care unit (ICU) of a university hospital between April 2017 and January 2020. Patients who survived despite invasive mechanical ventilation for >48 h, with a discharge period of >6 months, participated in the study. A questionnaire was sent to consenting patients to investigate the presence or absence of sensory impairment at that time, and treatment-related data were collected from their medical records. RESULTS: Of 75 eligible patients, 62 responded to our survey. Twenty-seven (43.6%) patients had some sensory impairment. Nine (14.5%) patients had chronic pain after ICU discharge, 4 (6.5%) had chronic pain and visual impairment, 3 (4.8%) had visual impairment only, and 3 (4.8%) had chronic pain and taste impairment. The most common overlapping symptom was a combination of chronic pain. CONCLUSIONS: Critically ill patients who survived and were discharged from the ICU accounted for 43.6% of patients with complaints of sensory impairment in the chronic phase. The results of this study suggest the need for follow-up and treatment of possible sensory impairment following ICU discharge.

OBJECTIVE: To investigate how omitting additional surgery after local excision (LE) affects patient outcomes in high-risk T1 colorectal cancer (CRC). BACKGROUND: It is debatable whether additional surgery should be performed for all patients with high-risk T1 CRC regardless of the tolerability of invasive procedures. METHODS: Patients who had received LE for T1 CRC at the Japanese Society for Cancer of the Colon and Rectum institutions between 2009 and 2016 were analyzed. Those who had received additional surgical resection and those who did not were matched one-on-one by the propensity score-matching method. A total of 401 propensity score-matched pairs were extracted from 1975 patients at 27 Japanese Society for Cancer of the Colon and Rectum institutions and were compared. RESULTS: Regional lymph node metastasis was observed in 31 (7.7%) patients in the LE + surgery group. Comparatively, the incidence of oncologic adverse events was low in the LE-alone group, such as the 5-year cumulative risk of local recurrence (4.1%) or overall recurrence (5.5%). In addition, the difference in the 5-year cancer-specific survival between the LE + surgery and LE-alone groups was only 1.8% (99.7% and 97.9%, respectively), whereas the 5-year overall survival was significantly lower in the LE-alone group than in the LE + surgery group [88.5% vs 94.5%, respectively ( P = 0.002)]. CONCLUSIONS: Those who had decided to omit additional surgery at the dedicated center for CRC treatment presented a small number of oncologic events and a satisfactory cancer-specific survival, which may suggest an important role of risk assessment regarding nononcologic adverse events to achieve a best practice for each individual with high-risk T1 tumors.

OBJECTIVE: The aim of this study was to determine the genuine prognostic relevance of primary tumor sidedness (PTS) in patients with early-stage colorectal cancer (CRC). BACKGROUND: The prognostic relevance of PTS in early-stage CRC remains a topic of debate. Several large epidemiological studies investigated survival only and did not consider the risk of recurrence so far. METHODS: Patients with stage II/III adenocarcinoma of the colon and upper rectum from 4 randomized controlled trials were analyzed. Survival outcomes were compared according to the tumor location: right-sided (cecum to transverse colon) or left-sided (descending colon to upper rectum). RESULTS: A total of 4113 patients were divided into a right-sided group (N=1349) and a left-sided group (N=2764). Relapse-free survival after primary surgery was not associated with PTS in all patients and each stage [hazard ratio (HR) adjusted =1.024 (95% CI: 0.886-1.183) in all patients; 1.327 (0.852-2.067) in stage II; and 0.990 (0.850-1.154) in stage III]. Also, overall survival after primary surgery was not associated with PTS in all patients and each stage [HR adjusted =0.879 (95% CI: 0.726-1.064) in all patients; 1.517 (0.738-3.115) in stage II; and 0.840 (0.689-1.024) in stage III]. In total, 795 patients (right-sided, N=257; left-sided, N=538) developed recurrence after primary surgery. PTS was significantly associated with overall survival after recurrence (HR adjusted =0.773, 95% CI: 0.627-0.954). CONCLUSIONS: PTS had no impact on the risk of recurrence for stage II/III CRC. Treatment stratification based on PTS is unnecessary for early-stage CRC.

We experienced a relatively rare case of synchronous breast and ovarian cancer in a patient with hereditary breast and ovarian cancer syndrome (HBOC). Here, we report the usefulness of laparoscopic examination to determine the subsequent treatment strategy in cases of suspected concurrent multiple carcinomas. Our patient was diagnosed with breast cancer following detection of a right breast mass. She was diagnosed with HBOC as she was found to be harboring a germline pathogenic variant of breast cancer susceptibility gene 1 (BRCA1). Preoperative images suggested the presence of neoplastic masses in the abdominal cavity, and the possibility of metastatic peritoneal dissemination of breast cancer or concurrent overlapping of gynecological malignancies was considered. We decided to employ laparoscopic examination, and if simultaneous overlapping of cancers was suspected, we planned to further evaluate whether primary debulking surgery (PDS) for gynecological cancer was possible or not. Laparoscopy revealed the presence of ovarian cancer with neoplastic lesions on the bilateral ovaries and disseminations in the pelvic and abdominal cavities. The total predictive index was 0; therefore, PDS was considered feasible. We performed a total mastectomy, followed by laparotomy, and optimal surgery was achieved. The final diagnosis was simultaneous stage IIB invasive ductal breast carcinoma and stage IIIC high-grade serous ovarian carcinoma. In this case of suspected concurrent multiple carcinomas, laparoscopy was beneficial for decision-making regarding subsequent surgical treatment. We believe that the use of laparoscopy will enable simultaneous surgery for breast cancer and ovarian cancer to become one of the treatment strategies in the future.

Ureteroenteric anastomotic strictures (UEAS) are typical complications after creating an ileal conduit for total pelvic exenteration (TPE) of rectal tumors. We report the ileal conduit for reconstruction in three patients, in the age-range of 47-73 years. Case 1 was when a left-sided UEAS had sufficient length of ureter for anastomosis, Case 2 was a right-sided UEAS with sufficient length of ureter for anastomosis, and Case 3 was a left-sided UEAS with insufficient length of ureter for anastomosis. There were no complications after operation and no recurrence of UEAS. It is important to learn the open surgical procedures for repair of a benign UEAS after TPE of rectal cancers. This has fewer complications and is safe in the long term.

BACKGROUND/AIM: Hyperchloremic metabolic acidosis after total pelvic exenteration (TPE) is relatively rare. Urinary diversion of the ileal conduit during TPE can result in increased urine reabsorption leading to hyperchloremic metabolic acidosis. We developed a new technique for the retrograde catheterization of a ureteral stent into an ileal conduit to treat hyperchloremic metabolic acidosis. CASE REPORT: A 70-year-old man underwent TPE for locally recurrent rectal cancer. Multiple episodes of complications, such as hyperchloremia and metabolic acidosis, occurred. Effective drainage of urine from the ileal conduit is crucial. With collaboration between an endoscopist and a radiologist, we developed a novel method for retrograde catheterization of the ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis after TPE. The patient's condition quickly improved after the procedure. CONCLUSION: Our novel technique of retrograde catheterization of a ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis could be adopted worldwide, as it is effective and safe.

Returning to work can be a serious issue for patients who have undergone intensive care. Previous studies have reported a relatively low return-to-work prevalence among such patients. Some patients with coronavirus disease 2019 (COVID-19) experience severe pneumonia and require intensive care, including mechanical ventilation. However, little is known about the return-to-work prevalence among such patients. Therefore, we conducted a systematic review and meta-analysis of the literature describing the return-to-work prevalence among COVID-19 patients who received intensive care. The eligibility criteria were determined based on the medical condition, context, and population framework of each study, as follows: (1) full-text observational studies, (2) context: COVID-19 patients admitted to ICU, (3) condition: return-to-work prevalence after ICU discharge, and (4) population: critically ill patients who are 18 years and older. Eligible studies included randomized controlled trials (RCTs) and observational studies. Review articles, case reports, letters to the editor, and comments without data involving return-to-work prevalence were excluded. We searched the Medical Literature Analysis and Retrieval System Online (MEDLINE, via PubMed), the Cumulated Index to Nursing and Allied Health Literature (CINAHL, via EBSCOhost), and the International Clinical Trials Registry Platform (ICTRP) databases from their inception till July 26, 2022, and updated the search on June 14, 2023. Specifically, we collected studies reporting data on the return-to-work prevalence among COVID-19 patients after receiving intensive care. Data extraction and quality assessment were performed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Prevalence Studies. Pre-developed standard forms were used for data collection, and pooled prevalence for return-to-work was calculated. Out of the 2221 available records, 42 full texts were reviewed, 20 of which were included in the qualitative synthesis. The number of return-to-work cases reported at 0-3 months, 4-6 months, and 7-12 months were three, 11, and nine, respectively. At 0-3 months, the pooled prevalence was 0.49 (three trials; n = 73; 95% CI: 0.15-0.84; I2 = 82%). At 4-6 months, the pooled prevalence was 0.57 (11 trials; n = 900; 95% CI: 0.40-0.73; I2 = 92%). Finally, at 7-12 months, the pooled prevalence was 0.64 (nine trials; n = 281; 95% CI: 0.50-0.77; I2 = 80%). However, the overall quality of the included studies was low. Based on the results, approximately one-third of COVID-19 patients did not return to work 12 months after receiving intensive care. Given the quality and limitations of the studies, a more detailed and extensive cohort study is required; also, concerned authorities should implement adequate measures in terms of providing integrated job support for this patient population.
