RESUMEN
Migraine is a disease that is difficult to be recognized by those around the patients, even though it causes significant hindrances. In this study, we conducted an exploratory comparison of the perceptions on migraine among patients, family members living with them, and physicians treating migraine patients. Patients and family members shared a common understanding on the pain of migraine, and hoped to spend more/better time together as a family. However, although family members felt compassion for the patients, lack of understanding by and patients' concern for the surroundings led to feelings of resignation and endurance on the side of patients. Regarding physicians' medical care, our results suggested the importance to understand the wishes and obstacles of each patient and to propose treatment accordingly. In order to reduce the burden of migraine, it is necessary to create an environment and raise awareness that allows people around the patients to understand and support the pain and hopes that each patient feels.

INTRODUCTION: The impacts of migraine on daily life, including daily activities and fundamental health indicators (sleep and mental health), have not been described in detail for people with migraine in Japan. METHODS: The cross-sectional ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE (OVERCOME [Japan]) study was conducted between July and September 2020. Impacts of migraine on housework, family/social/leisure activities, driving, and sleep were assessed using questions from the Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire, and Impact of Migraine on Partners and Adolescent Children scales and questions developed for OVERCOME (Japan). The Migraine Interictal Burden Scale (MIBS-4) evaluated burden on days without headaches. Depression and anxiety were assessed with the Patient Health Questionnaire (PHQ-8) and Generalized Anxiety Disorder (GAD-7) scales, respectively. Impacts on daily life were also described across MIDAS/MIBS-4 categories. RESULTS: Among 17,071 respondents with migraine, 24.8% required assistance with housework at least sometimes. Migraine interfered with relationships, leisure, and social activities at least sometimes for 31.8%, 41.6%, and 18.0% of respondents, respectively. Between headache days, 26.8% of respondents worried about planning social/leisure activities at least sometimes. Among respondents living with family (N = 13,548), migraine also had impacts on participation in and enjoyment of family activities. Among respondents who drove (N = 10,921), 43.9% reported that symptoms interfered with driving at least sometimes. Migraine interfered with sleep and mood at least sometimes for 52.7% and 70.7% of respondents, respectively. PHQ-8 and GAD-7 thresholds for clinical depression and anxiety were met by 28.6% and 22.0% of respondents, respectively. Impact of migraine on daily life increased with increasing severity of MIDAS/MIBS-4 categories. CONCLUSION: The burden of migraine on daily activities, sleep, and mental health is substantial for people with migraine in Japan. In clinical practice, it is important to evaluate the impact of migraine on daily life in addition to migraine symptoms.
RESUMEN
Using the Japanese version of the Impact of Migraine on Partners and Adolescent Children (IMPAC) and Family Question prepared based on IMPAC, we investigated the impact of migraine on family members from the perspectives of both patients and their family members. Our results showed that migraine had an impact on the family members living with the patients in Japan as well, and the perception of migraine differed partially between patients and their family members. We also found that the Japanese version of the IMPAC showed a correlation with existing instruments to evaluate impact of migraine, indicating its validity. The application of this study's findings in clinical practice could help alleviate the disease burden of migraine on patients and their family members.

OBJECTIVE: The purpose of this study was to evaluate the performance of algorithms for identifying cases of severe hypoglycemia in Japanese hospital administrative data. METHODS: This was a multicenter, retrospective, observational study conducted at 3 acute-care hospitals in Japan. The study population included patients aged ≥18 years with diabetes who had an outpatient visit or hospital admission for possible hypoglycemia. Possible cases of severe hypoglycemia were identified using health insurance claims data and Diagnosis Procedure Combination data. Sixty-one algorithms using combinations of diagnostic codes and prescription of high concentration (≥20% mass/volume) injectable glucose were used to define severe hypoglycemia. Independent manual chart reviews by 2 physicians at each hospital were used as the reference standard. Algorithm validity was evaluated using standard performance metrics. RESULTS: In total, 336 possible cases of severe hypoglycemia were identified, and 260 were consecutively sampled for validation. The best performing algorithms included 6 algorithms that had sensitivity ≥0.75, and 6 algorithms that had positive predictive values ≥0.75 with sensitivity ≥0.30. The best-performing algorithm with sensitivity ≥0.75 included any diagnoses for possible hypoglycemia or prescription of high-concentration glucose but excluded suspected diagnoses (sensitivity: 0.986 [95% confidence interval 0.959-1.013]; positive predictive value: 0.345 [0.280-0.410]). Restricting the algorithm definition to those with both a diagnosis of possible hypoglycemia and a prescription of high-concentration glucose improved the performance of the algorithm to correctly classify cases as severe hypoglycemia but lowered sensitivity (sensitivity: 0.375 [0.263-0.487]; positive predictive value: 0.771 [0.632-0.911]). CONCLUSION: The case-identifying algorithms in this study showed moderate positive predictive value and sensitivity for identification of severe hypoglycemia in Japanese healthcare data and can be employed by future pharmacoepidemiological studies using Japanese hospital administrative databases.

BACKGROUND AND OBJECTIVE: Real-world evidence on persistence of interleukin-17 inhibitors (IL-17i) as a drug class among Japanese patients with psoriasis is lacking. Hence, we aimed to describe persistence rates of IL-17is among patients with psoriasis including psoriasis vulgaris (PsO), psoriatic arthritis (PsA), and generalized pustular psoriasis (GPP) or erythrodermic psoriasis (EP) in Japan. METHODS: We analyzed claims data from the Medical Data Vision database. Patients ≥15 years old with a psoriasis diagnosis and an IL-17i prescription between November 2016 and August 2020 were included and followed through August 2021. Persistence rates of the IL-17i class among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP), and persistence rates of ixekizumab, secukinumab, or brodalumab among patients with PsO or PsA were analyzed using Kaplan-Meier method. Analyses were conducted in the bio-naïve and bio-experienced subgroups. RESULTS: The IL-17i class had >50% persistence rates up to 36 months among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP). 36-Month persistence rates for ixekizumab, secukinumab, and brodalumab were 46.2% to 57.7% in patients with PsO and 43.0% to 48.4% in patients with PsA. Across analyses, bio-naïve patients demonstrated similar or greater persistence rates than bio-experienced patients. CONCLUSION: IL-17is' persistence rates over 36 months were >50% among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP) in Japan.

Lethal giant larvae homolog 2 (LLGL2) and solute carrier family 7 member 5 (SLC7A5) have been reported to be involved in resistance to endocrine therapy. This study aimed to assess the effects of LLGL2/SLC7A5 co-expression in predicting prognosis and response to tamoxifen therapy in ERα-positive breast cancer patients according to LLGL2/SLC7A5 mRNA and protein expression in long-term follow-up invasive breast cancer tissues. We identified that low LLGL2/SLC7A5 mRNA co-expression (LLGL2low/SLC7A5low) was associated with disease-free survival (DFS) compared with other combination groups in all breast cancer patients. In ERα-positive breast cancer patients, LLGL2low/SLC7A5low showed longer DFS and overall survival (OS) compared with LLGL2high/SLC7A5high and a positive trend of longer survival compared with the other combination groups. We also observed that LLGL2low/SLC7A5low showed longer survival compared with LLGL2high/SLC7A5high in ERα-positive breast cancer patients receiving adjuvant tamoxifen therapy. Multivariate analysis demonstrated that LLGL2low/SLC7A5low was an independent favorable prognostic factor of both DFS and OS, not only in all breast cancer patients, but also in ERα-positive breast cancer patients. High co-expression of LLGL2 and SLC7A5 protein showed a positive trend of shorter survival. Our study showed that co-expression of LLGL2 and SLC7A5 mRNA is a promising candidate biomarker in early breast cancer patients.

The purpose of this study was to investigate adherence to adjuvant endocrine therapy (ET) and the factors affecting demotivation and motivation to continue adjuvant ET. In patients with hormone receptor-positive breast cancer in Japan, an online survey was conducted from June to July 2021 to investigate the treatment effects, side effects, concerns about side effects(for demotivation only), convenience of hospital visits, treatment duration, concerns about recurrence/progression, treatment cost, support from healthcare professionals, and support from family, the patient association, and peers(for motivation only). According to the responses from 263 patients, the most common factor affecting demotivation to continue adjuvant ET was the burden of side effects, and the most common factor affecting motivation to continue adjuvant ET was concerns about recurrence/progression. Continuous relief of the burden of side effects from the early stage of treatment, and mental support for concerns about recurrence/progression, as well as explaining and promoting the risks and benefits of continuing treatment, are considered to lead to motivation to continue adjuvant ET(Fig. 1: Summary of this survey).

OBJECTIVES: To evaluate neonatal outcomes after the use of a cervical pessary in Japanese women with short cervical length (CL) less than 25 mm. METHODS: This multicenter study involved women with singleton pregnancies between 20 and 29+6 gestational weeks and a CL of less than 25 mm. The primary outcome was preterm birth (PTB) before 34 weeks of gestation. This study was registered in the Japan Registry of Clinical Trials (JRCT: jRCTs042180102). RESULTS: Two hundred pregnant women were enrolled; 114 in the pessary group and 86 in the expectant management group as controls. In the pessary group, all 114 neonates were investigated for perinatal outcomes, and 112 pregnant women were investigated for primary, and secondary outcomes. In the control group, 86 pregnant women were investigated for primary and secondary outcomes and 86 neonates were investigated for neonatal outcomes. There were no significant differences in PTB in ≤34, ≤37, and ≤28 weeks of gestation or in preterm rupture of membranes (PROM) ≤34 weeks between the groups. The gestational weeks at birth and birth weight were significantly higher in the pessary group. Regression analysis demonstrated that the CL decreased without a pessary, whereas the shortening rate was suppressed during the intervention. No significant differences were observed in adverse neonatal outcomes, chorioamnionitis, or preterm PROM. CONCLUSIONS: The cervical pessary effectively reduced CL shortening during pregnancy resulting in an average increased gestational age, however, did not reduced the rates of preterm birth.

HECT domain E3 ubiquitin ligase 1 (HECTD1) has been reported to be a negative regulator of epithelial-mesenchymal transition and to decrease breast cancer invasion and metastasis. However, the clinical significance and detailed role of HECTD1 in breast cancer remain elusive. We investigated the role of HECTD1 in two large breast cancer cohorts at our institution and The Cancer Genome Atlas using mRNA expression and bioinformatics analysis. We also examined the prognostic significance of HECTD1 mRNA expression by multivariate analysis and HECTD1 protein expression by immunohistochemistry using our cohort. HECTD1 mRNA expression was significantly lower in breast cancer tissues compared with those in adjacent normal tissues (P<0.001). HECTD1 mRNA expression levels also differed among breast cancer subtypes. Decreased HECTD1 mRNA expression was significantly associated with aggressive tumor characteristics, including large tumor size and high histological grade. HECTD1 mRNA expression was inversely associated with mitochondrial cellular respiratory function (oxidative phosphorylation (P<0.001, FDR q-value <0.001) the respiratory chain complex (P<0.001, FDR q-value <0.001) and reactive oxygen species (P<0.001, FDR q-value <0.001), but not with epithelial-mesenchymal transition, in breast cancer tissues. Low expression of HECTD1 mRNA was associated with shorter disease-free survival (log-rank: P=0.013) and overall survival (log-rank: P=0.038) in breast cancer patients. Multivariate analysis also identified low HECTD1 mRNA expression level as an independent risk factor for disease-free (hazard ratio: 1.54, 95% confidence interval: 1.11-2.13, P=0.009) and overall (hazard ratio: 1.50, 95% confidence interval: 1.01-2.24, P=0.046) survival among breast cancer patients. There was no association of HECTD1 protein expression with HECTD1 mRNA expression and prognosis. In conclusion, we identified low expression of HECTD1 mRNA as an independent poor prognostic factor in breast cancer and showed that HECTD1 mRNA expression was inversely correlated with genes involved in mitochondrial cellular respiratory function in breast cancer.
RESUMEN
BACKGROUND/AIMS: Although risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records. METHODS: We used health checkup records between April 2004 and March 2014 at 9 institutions in Japan. A multivariate logistic regression analysis was performed to evaluate associations of baseline clinical parameters with RE. The time courses of the clinical parameters of RE subjects were compared with those of non-RE subjects by the mixed-effects models for repeated measures analysis or longitudinal multivariate logistic analysis. RESULTS: Initial data were obtained from 230 056 individuals, and 2066 RE subjects and 4132 non-RE subjects were finally included in the analysis. Body mass index, alanine aminotransferase, smoking, acid reflux symptoms, hiatal hernia, and absence of atrophic gastritis at baseline were independently associated with RE. The time courses of body mass index, fasting blood sugar, triglyceride, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, percentages of acid reflux symptoms, feeling of fullness, and hiatal hernia in the RE group were significantly worse than in the non-RE group. CONCLUSIONS: The RE group displayed a greater worsening of the clinical parameters associated with lifestyle diseases, including obesity, diabetes, hyperlipidemia, and fatty liver for 5 years before RE onset compared with the non-RE group. These results suggest that RE is a lifestyle disease and thus lifestyle guidance to at-risk person may help to prevent RE onset.
RESUMEN
Bortezomib (Btz) shows robust efficacy in patients with multiple myeloma (MM); however, some patients experience suboptimal responses and show specific toxicities. Therefore, we attempted to identify specific HLA alleles associated with Btz-related toxicities and response to treatment. Eighty-two transplant-ineligible patients with newly diagnosed MM enrolled in a phase II study (JCOG1105) comparing two less intensive melphalan, prednisolone, plus Btz (MPB) regimens were subjected to HLA typing. The frequency of each allele was compared between the groups, categorized based on toxicity grades and responses to MPB therapy. Among 82 patients, the numbers of patients with severe peripheral neuropathy (PN; grade 2 or higher), skin disorders (SD; grade 2 or higher), and pneumonitis were 16 (19.5%), 15 (18.3%), and 6 (7.3%), respectively. Complete response was achieved in 10 (12.2%) patients. Although no significant HLA allele was identified by multiple comparisons, several candidates were identified. HLA-B*40:06 was more prevalent in patients with severe PN than in those with less severe PN (odds ratio [OR] = 6.76). HLA-B*40:06 and HLA-DRB1*12:01 were more prevalent in patients with SD than in those with less severe SD (OR = 7.47 and OR = 5.55, respectively). HLA-DRB1*08:02 clustered in the group of patients with pneumonitis (OR = 11.34). Complete response was achieved in patients carrying HLA-DQB1*03:02, HLA-DQB1*05:01, and HLA-DRB1*01:01 class II alleles. HLA genotyping could help predict Btz-induced toxicity and treatment efficacy in patients with MM, although this needs further validation.

A subset of essential thrombocythemia (ET) cases are negative for disease-defining mutations on JAK2, MPL, and CALR and defined as triple negative (TN). The lack of recurrent mutations in TN-ET patients makes its pathogenesis ambiguous. Here, we screened 483 patients with suspected ET in a single institution, centrally reviewed bone marrow specimens, and identified 23 TN-ET patients. Analysis of clinical records revealed that TN-ET patients were mostly young female, without a history of thrombosis or progression to secondary myelofibrosis and leukemia. Sequencing analysis and human androgen receptor assays revealed that the majority of TN-ET patients exhibited polyclonal hematopoiesis, suggesting a possibility of reactive thrombocytosis in TN-ET. However, the serum levels of thrombopoietin (TPO) and interleukin-6 in TN-ET patients were not significantly different from those in ET patients with canonical mutations and healthy individuals. Rather, CD34-positive cells from TN-ET patients showed a capacity to form megakaryocytic colonies, even in the absence of TPO. No signs of thrombocytosis were observed before TN-ET development, denying the possibility of hereditary thrombocytosis in TN-ET. Overall, these findings indicate that TN-ET is a distinctive disease entity associated with polyclonal hematopoiesis and is paradoxically caused by hematopoietic stem cells harboring a capacity for cell-autonomous megakaryopoiesis.

Reflux esophagitis is known to be more prevalent in males, and previous studies have suggested sex differences in its risk factors. However, little is known about sex differences in the time-course of risk factors before reflux esophagitis onset. Thus, we conducted a retrospective longitudinal study using health checkup records. From the records of 230,056 individuals obtained from nine institutes in Japan, we selected 1,558 male reflux esophagitis cases, 3,116 male controls, 508 female reflux esophagitis cases, and 1,016 female controls were selected. We compared time-courses of risk factors between the case and control groups and identified abdominal circumference (AC), diastolic blood pressure, alanine transaminase (ALT), and current smoking in males and body mass index (BMI) in females as sex-specific risk factors. We also found that AC and ALT in males and BMI in females were significantly different between the reflux esophagitis case and control groups during the five years before reflux esophagitis onset. Our results suggest that visceral fat-type obesity and fatty liver in males and higher BMI in females are more frequently observed in reflux esophagitis cases several years before reflux esophagitis onset, and that proactive intervention to lifestyle can help prevent reflux esophagitis in both males and females.
RESUMEN
BACKGROUND: Although chronic postsurgical pain (CPSP) after breast cancer surgery is a common and prevalent postsurgical adverse event, the need for CPSP treatment has not been investigated. This study examined the proportion of patients who needed treatment for CPSP and associated predictors. METHODS: We conducted a cross-sectional study with female patients who underwent breast cancer surgery at our institution. Participants were aged ≤ 65 years at the time of this study and were at least 1 year post surgery. The questionnaire examined the presence of and need for treatment for CPSP and included the Japanese version of the Concerns about Recurrence Scale (CARS-J). Multivariate analyses were used to identify independent predictors of needing treatment for CPSP. RESULTS: In total, 305 patients completed the questionnaire. The mean time since surgery was 67.1 months; 156 (51%) patients developed CPSP after breast cancer surgery and 61 (39%) needed treatment for CPSP. Among patients that developed CPSP, the fear of breast cancer recurrence as assessed by the CARS-J (odds ratio [OR] 2.59, 95% confidence interval [CI] 1.14-6.28, P = 0.028) and ≥ 2 postsurgical pain regions (OR 2.52, 95% CI 1.16-5.57, P = 0.020) were independent predictors of needing treatment for CPSP. CONCLUSIONS: This study is the first to identify the proportion and predictors of patients who need treatment for CPSP. Fear of breast cancer recurrence and ≥ 2 postsurgical pain regions may predict the need for CPSP treatment among patients following breast cancer surgery.

In end-of-life care, rehabilitation for terminally ill cancer patients is inconsistently provided and rarely discussed. We sought to clarify the prevalence of unmet rehabilitation need for patients admitted to inpatient hospice/palliative care units as perceived by bereaved family members. We conducted a nationwide questionnaire survey of 1001 family members of cancer patients who died at inpatient hospices/palliative care units. For cancer patients who did not receive rehabilitation, we asked if family members perceived that the patient would have wanted rehabilitation intervention. Data were obtained from 416 respondents. Of these, 281 (67.5%) cases received no rehabilitation. The need for physical modalities was the most frequently reported (27.8%; 95% CI: 22.6-33.4), followed by relief of dyspnea (25.6%; 95% CI: 20.6-31.1) and treatment of edema (23.8%; 95% CI: 19.0-29.3). A non-negligible proportion of bereaved families reported unmet need for rehabilitation related to symptom management in inpatient hospices/palliative care units.

BACKGROUND: Antegrade percutaneous ureterolithotripsy (URSL) could be a treatment option for large and/or impacted proximal ureteral stones, which are difficult to treat. To review the current approach and treatment outcomes and to compare the efficacy of retrograde and antegrade URSL for large proximal ureteral stones, we evaluated the unique perspectives of both surgical modalities. METHODS: This systematic literature review and meta-analysis was performed in July 2020. Articles on human studies and treatment of ureteral stones with URSL were extracted from the PubMed, MEDLINE, Embase, Cochrane Library, Scopus, and the Japan Medical Abstracts Society databases without any language restrictions. The risks of bias for randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) were assessed using the Cochrane risk of tool and the Risk of Bias in Non-randomized Studies- of Interventions tool, respectively. RESULTS: A total of 10 studies, including seven RCTs and three non-RCTs, were selected for the analysis; 433 and 420 cases underwent retrograde and antegrade URSL, respectively. The stone-free rate (SFR) was significantly higher in antegrade URSL than in retrograde URSL (SFR ratio: 1.17, 95% CI: 1.12-1.22; P<0.001), while the hospital stay was significantly longer in antegrade URSL than in retrograde URSL (standardized mean difference: 2.56, 95% CI: 0.67-4.46; P=0.008). There were no significant differences in the operation time and the overall complication rate between the two approaches. CONCLUSIONS: Despite the heterogeneity of data and bias limitations, this latest evidence reflects real practice data, which may be useful for decision making.
RESUMEN
PURPOSE: Retinoic acid-induced 2 (RAI2) has been shown to be a putative suppressor of the early hematogenous dissemination of tumor cells to the bone marrow in breast cancer. Here, we investigated the associations of RAI2 mRNA and protein expression with clinicopathological factors and prognosis in breast cancer patients with long-term follow-up. METHODS: Invasive breast cancer tissues (n = 604) were analyzed for RAI2 mRNA expression. We examined the associations of clinicopathological factors with the expression levels of RAI2 mRNA in these samples. We also analyzed RAI2 protein expression by immunohistochemistry in invasive breast cancer tissues (n = 422). RESULTS: We identified significant positive associations between low expression of RAI2 mRNA and shorter disease-free survival (DFS), breast-cancer-specific survival (BCSS), and overall survival (OS) in breast cancer patients. We also identified significant positive associations between negative for RAI2 protein expression and shorter DFS, BCSS, and OS in breast cancer patients. Low RAI2 mRNA and negative for RAI2 protein expression were positively associated with larger tumor size, higher tumor grade, and ERα-negativity. Multivariate analyses indicated that not only RAI2 mRNA but also RAI2 protein expression were independent risk factors for both DFS and BCSS in breast cancer patients. The median follow-up periods were 10.3 and 9.3 years for the RAI2 mRNA and protein expression analyses, respectively. CONCLUSIONS: Our findings suggest that RAI2 has a role in the metastasis of breast cancer, and that RAI2 expression could be a promising candidate biomarker of prognosis in breast cancer patients.

The purpose of this study was to examine differences in texture features between olfactory neuroblastoma (ONB) and sinonasal squamous cell carcinoma (SCC) on contrast-enhanced CT (CECT) images, and to evaluate the predictive accuracy of texture analysis compared to radiologists' interpretations. Forty-three patients with pathologically-diagnosed primary nasal and paranasal tumor (17 ONB and 26 SCC) were included. We extracted 42 texture features from tumor regions on CECT images obtained before treatment. In univariate analysis, each texture features were compared, with adjustment for multiple comparisons. In multivariate analysis, the elastic net was used to select useful texture features and to construct a texture-based prediction model with leave-one-out cross-validation. The prediction accuracy was compared with two radiologists' visual interpretations. In univariate analysis, significant differences were observed for 28 of 42 texture features between ONB and SCC, with areas under the receiver operating characteristic curve between 0.68 and 0.91 (median: 0.80). In multivariate analysis, the elastic net model selected 18 texture features that contributed to differentiation. It tended to show slightly higher predictive accuracy than radiologists' interpretations (86% and 74%, respectively; P = 0.096). In conclusion, several texture features contributed to differentiation of ONB from SCC, and the texture-based prediction model was considered useful.

PURPOSE: Improving the safety of general wards is a key to reducing serious adverse events in the postoperative period. We investigated the characteristics, treatment, and outcomes of postoperative patients managed by a rapid response system (RRS) in Japan to improve postoperative management. METHODS: This retrospective study analyzed cases requiring RRS intervention that were included in the In-Hospital Emergency Registry in Japan. We analyzed data reported by 34 Japanese hospitals between January 2014 and March 2018, mainly focusing on postoperative patients for whom the RRS was activated within 7 days of surgery. Non-postoperative patients, for whom the RRS was activated in all other settings, were used for comparison as necessary. RESULTS: There were 609 (12.7%) postoperative patients among the total patients in the registry. The major criteria were staff concerns (30.2%) and low oxygen saturation (29.7%). Hypotension, tachycardia, and inability to contact physicians were observed as triggers significantly more frequently in postoperative patients when compared with non-postoperative patients. Among RRS activations within 7 days of surgery, 68.9% of activations occurred within postoperative day 3. The ordering of tests (46.8%) and fluid bolus (34.6%) were major interventions that were performed significantly more frequently in postoperative patients when compared with non-postoperative patients. The rate of RRS activations resulting in ICU care was 32.8%. The mortality rate at 1 month was 16.2%. CONCLUSION: Approximately, 70% of the RRS activations occurred within postoperative day 3. Circulatory problems were a more frequent cause of RRS activation in the postoperative group than in the non-postoperative group.
