Blood Interleukin-18 (IL-18) and IL-18 Binding Protein (IL-18BP) Levels Following Midline Laparotomy: A Prospective Randomized Study of Patients With Benign Disease and Patients With Cancer.

BACKGROUND/AIM: The acute phase immune response (APR) in midline laparotomy (MLa) patients following surgery has been rarely studied, with no studies assessing the association of blood IL-18 (interleukin-18) and IL-18BP (IL-18 binding protein) values with the numeric rating scale (NRS) pain score following MLa. PATIENTS AND METHODS: Blood levels of seven cytokines (CYT) (IL-18, IL-18BP, IL-1ra, IL-6, IL-8, IL-10, IL-1ß) and high-sensitivity C-reactive protein (hs-CRP) were measured at three time points; before operation (PRE), immediately after operation (POP1), and 24 h after operation (POP2) in 56 patients with MLa. The satisfaction of the patients at 24 h following MLa (SFS24; 0=fully unsatisfied; 10=fully satisfied) was recorded on a 11-point numeric rating scale. RESULTS: In all patients, the IL-18 and IL-18BP blood levels decreased at POP1 and the drop between the preoperative and POP1 levels in the IL-18 and IL-18BP was highly significant (p<0.001). However, the median IL-18 and IL-18BP blood levels increased significantly at POP2 (p<0.001) with the linear mixed-effect model (LME) showing a statistically significant time effect (p<0.001). The hs-CRP blood levels increased significantly at POP2 with the LME model showing a statistically significant time effect. The preoperative and POP2 IL-18 values were clearly higher in patients with cancer versus benign disease (177/182 vs. 135/126, p=0.039/p=0.013, respectively). Interestingly, in all patients of the study, the median IL-18 versus IL-18BP blood levels correlated at POP1 (r=0.315, p=0.036). CONCLUSION: A noteworthy discovery of this study is the correlation of IL-18BP with SFS24 (r=0.361, p=0.05), proposing that APR and quality of life are associated in MLa patients.

Patient-reported Outcome Measure (PROM) Rand-36-item Health Survey for Gallstone Disease Patients Five Years Following Surgery: A Prospective Randomized Study.

BACKGROUND/AIM: There are no studies assessing the long-term quality of life (QoL) following three-dimensional laparoscopy cholecystectomy (3D-LC) in patients with cholelithiasis (Chole). PATIENTS AND METHODS: A cohort of 200 patients with Chole were randomized into 3D-LC or minilaparotomy cholecystectomy (MC) groups. RAND-36 survey was performed before randomization, four weeks and five years postoperatively. RESULTS: Similar postoperative five years RAND-36 scores were reported in the 3D-LC and MC groups. The MC and 3D-LC groups combined analysis, social functioning (SF, p=0.007), mental health (MH, p=0.001), role physical (RP, p<0.001) and bodily pain (BP, p<0.001) domains increased significantly. In comparison to the Finnish reference RAND-36 (FRR) scores, the scores at five years increased significantly in the MH domain, while four RAND-36 domains; Physical functioning (PF), general health (GH), RP, BP remained significantly lower in comparison to the FRR scores. CONCLUSION: A relatively similar long-term outcome in the 3D-LC and MC patients is shown. Interestingly, five RAND-36 domains increased during five years follow-up, while four RAND-36 domains remained lower than FRR scores, which may indicate onset of possible new symptoms following cholecystectomy in long-term follow-up.

High Numbers of CD163+ Tumor-Associated Macrophages Predict Poor Prognosis in HER2+ Breast Cancer.

Tumor-associated macrophages (TAMs) are associated with a poor outcome in breast cancer (BC), but their prognostic value in different BC subtypes has remained somewhat unclear. Here, we investigated the prognostic value of M2-like TAMs (CD163+) and all TAMs (CD68+) in a patient cohort of 278 non-metastatic BC patients, half of whom were HER2+ (n = 139). The survival endpoints investigated were overall survival (OS), breast cancer-specific survival (BCSS) and disease-free survival (DFS). In the whole patient cohort (n = 278), a high CD163+ TAM count and a high CD68+ TAM count were associated with a worse outcome (p ≤ 0.023). In HER2+ BC, a high CD163+ TAM count was an independent factor for a poor prognosis across all the investigated survival endpoints (p < 0.001). The prognostic effect was evident in both the HER2+/hormone receptor-positive (p < 0.001) and HER2+/hormone receptor-negative (p ≤ 0.012) subgroups and regardless of the provision of adjuvant trastuzumab (p ≤ 0.002). In HER2-negative BC, the CD163+ TAM count was not significantly associated with survival. These results suggest that a high CD163+ TAM count predicts an inferior outcome, especially in HER2+ BC patients, and as adjuvant trastuzumab did not overcome the poor prognostic effect, combination treatments including therapies targeting the macrophage function could represent an effective therapeutic approach in HER2+ BC.

A novel score for predicting 1-year mortality of intensive care patients.

BACKGROUND: We aimed to develop a simple scoring table for predicting probability of death within 1-year after admission to an intensive care unit. We analysed data on emergency admissions from the nationwide Finnish intensive care quality registry. METHODS: We included first admissions of adult patients with data available on 1-year vital status (dead or alive) and all five variables included in a premorbid functional status score, which is the number of activities the person can manage independently of the following five: get out of bed, move indoors, dress, climb stairs and walk 400 m. We analysed data on patient characteristics and admission-associated factors from 2012 to 2014 to find predictors of 1-year mortality and to develop a score for predicting probability of death. We tested the performance of this score in data from 2015. We assessed the 1-year functional status score of survivors with data available. RESULTS: Out of 25,261 patients, 20,628 (81.7%) patients were able to perform all five functional activities independently prior to the intensive care unit admission. At 1-year post admission, 19,625 (77.7%) patients were alive. 1-year functional status score was known for 11,011 patients and 8970 (81.5%) patients achieved functional status score 5, managing all five activities independently. The score based on age, sex, preceding functional status, type of intensive care unit admission, severity of acute illness and the most significant diagnoses predicted 1-year mortality with an area under the receiver operating characteristic curve 0.78 (95% CI, 0.76-0.79). The calibration of our prediction model was good, with calibration intercept -0.01 (-0.07 to 0.05) and calibration slope 0.96 (0.90 to 1.02). CONCLUSION: Our score based on data available at intensive care unit admission predicted 1-year mortality with fairly good discrimination. Most survivors achieved good functional recovery.

Critical limb-threatening ischaemia and microvascular transformation: clinical implications.

BACKGROUND AND AIMS: Clinical management of critical limb-threatening ischaemia (CLTI) is focused on prevention and treatment of atherosclerotic arterial occlusions. The role of microvascular pathology in disease progression is still largely unspecified and more importantly not utilized for treatment. The aim of this explorative study was to characterize the role of the microvasculature in CLTI pathology. METHODS: Clinical high-resolution imaging of CLTI patients (n = 50) and muscle samples from amputated CLTI limbs (n = 40) were used to describe microvascular pathology of CLTI at the level of resting muscle blood flow and microvascular structure, respectively. Furthermore, a chronic, low arterial driving pressure-simulating ischaemia model in rabbits (n = 24) was used together with adenoviral vascular endothelial growth factor A gene transfers to study the effect of microvascular alterations on muscle outcome. RESULTS: Resting microvascular blood flow was not depleted but displayed decreased capillary transit time (P < .01) in CLTI muscles. Critical limb-threatening ischaemia muscle microvasculature also exhibited capillary enlargement (P < .001) and further arterialization along worsening of myofibre atrophy and detaching of capillaries from myofibres. Furthermore, CLTI-like capillary transformation was shown to worsen calf muscle force production (P < .05) and tissue outcome (P < .01) under chronic ischaemia in rabbits and in healthy, normal rabbit muscle. CONCLUSIONS: These findings depict a progressive, hypoxia-driven transformation of the microvasculature in CLTI muscles, which pathologically alters blood flow dynamics and aggravates tissue damage under low arterial driving pressure. Hypoxia-driven capillary enlargement can be highly important for CLTI outcomes and should therefore be considered in further development of diagnostics and treatment of CLTI.

The Diagnostic Accuracy (DA) of ColonView Fecal Immunochemical Test (FIT) in Detecting Colorectal Adenoma (CRA) Can Be Improved by the Diagnostic Models (DM) that Include Triage and Risk Features of CRA.

BACKGROUND/AIM: This study assessed whether the diagnostic accuracy (DA) of ColonView (CV) fecal immunochemical test (FIT) in detecting colorectal adenoma (CRA) can be improved by the diagnostic models (DM) that include triage and risk features of CRA. PATIENTS AND METHODS: A total of 5,090 participants of colorectal neoplasia (CRN) screening were recruited prospectively between January 2014 and December 2016. The CRN cohort of 486 patients included 222 CRA patients and 264 non-CRA patients of whom three consecutive fecal samples were analyzed by two fecal occult blood (FOB) assays (CV FIT test, HemoccultSENSA test). Hierarchical multilevel logistic models were used to test the DA of CV test and DMs, visualised as hierarchical summary receiving operating characteristic (HSROC) curves. RESULTS: In conventional receiving operating characteristic (ROC) analysis, the area under the curve (AUC) values of the age, height, weight, and body mass index (BMI) were 0.60, 0.57, 0.54, and 0.51, respectively. The AUC values for different DMs ranged from 0.69 (for DM without triage I/II and SENSA), and the highest AUC value of 0.70 was reached for DM with all variables included. In HSROC analysis, the AUC values for i) lowR variables, ii) highR variables, and ii) DMs were as follows: i) AUC=0.506, ii) AUC=0.566 and iii) AUC=0.732. The differences in AUC values were: between i) and ii) p=0.008; between i) and iii) p<0.0001; between ii) and iii) p<0.0001. CONCLUSION: The results demonstrated that DMs, particularly those including risk factors, significantly improved the DA of the CV FIT test in detecting CRA compared to traditional low-risk (lowR) and high-risk (highR) features alone. This study provides novel evidence supporting the enhanced diagnostic performance of DMs in combination with CV FIT testing for the detection of CRA.

A practical prognostic peripheral blood-based risk model for the evaluation of the likelihood of a response and survival of metastatic cancer patients treated with immune checkpoint inhibitors.

BACKGROUND: Less than half of unselected metastatic cancer patients benefit from the immune checkpoint inhibitor (ICI) therapy. Systemic cancer-related inflammation may influence the efficacy of ICIs and thus, systemic inflammatory markers could have prognostic and/or predictive potential in ICI therapy. Here, we aimed to identify a combination of inflammation-related laboratory parameters to establish a practical prognostic risk model for the pretreatment evaluation of a response and survival of ICI-treated patients with different types of metastatic cancers. METHODS: The study-cohort consisted of a real-world patient population receiving ICIs for metastatic cancers of different origins (n = 158). Laboratory parameters determined before the initiation of the ICI treatment were retrospectively collected. Six inflammation-related parameters i.e., elevated values of neutrophils, platelets, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and lactate dehydrogenase (LDH), and the presence of anemia, were each scored with one point, giving 0-6 risk points for each patient. The patients with information of all these six parameters (n = 109) were then stratified into low-risk (0-3 points) and high-risk (4-6 points) groups. The overall response rate (ORR), overall survival (OS), and progression-free survival (PFS) according to the risk scores were determined. RESULTS: The risk model was strongly associated with the outcome of the patients. The ORR to ICI treatment in the high-risk group was 30.3% in comparison to 53.9% in the low-risk group (p = 0.023). The medians for OS were 10.0 months and 27.3 months, respectively (p < 0.001), and the corresponding medians for PFS were 3.9 months and 6.3 months (p = 0.002). The risk group remained as a significant prognostic factor for both OS (HR 3.04, 95% CI 1.64-5.64, p < 0.001) and PFS (HR 1.79, 95% CI 1.04-3.06, p = 0.035) in the Cox multivariate analyses. CONCLUSIONS: We propose a readily feasible, practical risk model consisted of six inflammation-related laboratory parameters as a tool for outcome prediction in metastatic cancer patients treated with ICIs. The risk model was strongly associated with the outcome of the patients in terms of all the evaluated indicators i.e., ORR, OS and PFS. Yet, further studies are needed to validate the risk model.

Twenty years' experience of type B aortic dissections: a population-based national registry study from Finland.

OBJECTIVES: The objective of this study was to investigate the incidence, treatment and survival of Stanford type B aortic dissection (BTAD) during 20 years in the Finnish population. METHODS: Data collection was made from the Nationwide Care Register for Health Care, Finnish National Institute for Health and Welfare. All patients over 15 years of age with BTAD from 2000 to 2019 were included in the study. A data search of the Registry of Death Cause (Statistic Finland) was carried out to identify the date and cause of death. RESULTS: There were 1742 cases of BTAD during the study period. BTAD represented 45.6% of all aortic dissections leading to hospital admission. Incidence for BTAD was 1.62 per 100 000 inhabitants per year. The median survival was 12.7 years [95% confidence interval (CI) 9.63-14.7], 12.4 years (95% CI 10.5-14.4) and 8.6 years (95% CI 7.5-9.7) for patients treated with thoracic endovascular aortic repair (TEVAR), surgery and medical treatment (MT), respectively. Survival was significantly better after TEVAR and surgery, compared to MT only (P < 0.001). Age-adjusted survival was significantly better after TEVAR compared to patients treated with MT or surgery (hazard ratio 0.578, 95% CI 0.420-0.794, P < 0.001). Aortic-related death was the most common cause of death in all groups (41%). CONCLUSIONS: The incidence of BTAD seems to be similar in the Finnish population compared to other populational studies. Patients treated with TEVAR had significantly better survival compared to other patients. A high risk for late aortic-related death should be recognized in patients with BTAD.

Triage Process at Endoscopy With ColonView Fecal Immunochemical Test (FIT) Will Enhance Diagnostic Accuracy (DA) of Colorectal Cancer Screening.

BACKGROUND/AIM: This study assessed the diagnostic accuracy (DA) of the predictive features of colorectal cancer (CRC, predictCRC), triage process (triage), and ColonView (CV) fecal immunochemical test (FIT) in a CRC screening setting. The diagnostic score models (DMs) including predictCRC with triage and CV test were also calculated. PATIENTS AND METHODS: The study cohort of 544 patients included 58 CRC patients and 486 non-CRC patients who submitted three consecutive fecal samples for analysis, by two fecal occult blood (FOB) assays (CV FIT test, HemoccultSENSA test). Hierarchical multilevel logistic models were used to test the DA (for CRC) of each item of predictCRC (with triage I and II) and DMs, visualized as hierarchical summary receiving operating characteristic (HSROC) curves. RESULTS: The DA of the predictCRC location of neoplasm (Loc), triage I, and triage II showed 49%, 41%, and 93% sensitivity (Se), and 70%, 99.5%, and 88% specificity (Sp), respectively. The PPV+ of triage I (92%) was higher than that of Loc (22%) or triage II test (45%). In the conventional receiver operating characteristic (ROC) analysis, the area under the curve (AUC) values for the different DMs ranged from 0.880 (for DM without triage I and II), whereas the highest AUC value of 0.960 was reached for DM with triage I and II included in the formula. In the HSROC analysis, the AUC values were as follows: i) with all predictCRCs, AUC=0.717 and ii) with DMs, AUC=0.937. In the roccomp analysis, the difference in AUC values between i) and ii) was statistically significant (p<0.0001). CONCLUSION: In the detection of CRC, the DA of the new DMs with triage was far superior to that of DMs without triage. This is the first study to report evidence of improved DA in the detection of CRC using DMs including predictCRC with triage and CV FIT test.

Plasma N-terminal pro-B-type natriuretic peptide in the detection of aortic valve stenosis.

BACKGROUND: Systolic murmur suggestive of aortic valve origin is a common accidental finding, particularly in the elderly. Usually, it is due to aortic stenosis (AS) or aortic sclerosis (ASc). Currently, echocardiography is used to differentiate AS from ASc. Plasma N-terminal (NT)-prohormone BNP (NT-proBNP) is known to correlate with the severity of AS. We assessed whether NT-proBNP separates AS from ASc. METHODS: The study population consisted of three groups: AS (n = 87, age 77 ± 7 years), ASc (n = 76, age 72 ± 10 years), and healthy controls (n = 101, age 55 ± 10 years). All subjects underwent transthoracic echocardiography and measurement of plasma NT-proBNP. Patients with diseases known to increase NT-proBNP were excluded. RESULTS: The crude plasma NT-proBNP (median; IQR) in AS patients (413; 165-1055 ng/l) was significantly higher compared to ASc patients (96; 53-237 ng/l, p < 0.001) and healthy controls (50; 29-76 ng/l, p < 0.001). After adjusting for the confounding factors (age, coronary artery disease, renal function and diastolic blood pressure), plasma NT-proBNP remained significantly higher in AS patients as compared to ASc (p < 0.002) and controls (p < 0.0001). In the receiver-operating characteristic curve for NT-proBNP to identify AS from ASc and controls, the area under the curve was 0.878 with optimal cutoff of 115 ng/l. In addition, using 115 ng/l to separate AS from ASc yielded sensitivity of 0.885, and negative predictive value of 0.808. CONCLUSIONS: NT-proBNP was sensitive to identify AS and useful to rule out AS in patients with systolic murmur in the left ventricular outflow tract provided the patient does not have coexisting disease known to impact NT-proBNP.

Accuracy of Prediction Models in Diagnosis of Acute Diverticulitis.

BACKGROUND/AIM: The diagnostic score models (DMs) for patients with acute diverticulitis (AcDi) have been rarely evaluated. Therefore, we tried to develop diagnostic models (DMs) to enhance the diagnostic accuracy (DA) of AcDi. PATIENTS AND METHODS: In this AAP (acute abdominal pain) cohort, 30 AcDi patients were compared to 1,303 non-AcDi patients, with regard to their i) clinical symptoms (n=22), ii) signs and tests (n=14) as well as iii) laboratory analyses (n=3). The triage was performed at patient arrival to the emergency department (ED) (triage I) and at follow-up (triage II) before final decision. The triage included a suggested diagnosis of the AAP patient. Bivariate random effects meta-analysis was performed separately for 1) the pooled symptoms (n=22), 2) signs & tests (n=17) as well as 3) pooled DMs (I-V) with different cut-offs (with or without triage) to assess the diagnostic accuracy (DA) in detection of AcDi by HSROC (hierarchical summary receiver operating characteristic) curves. RESULTS: In the conventional receiver operating characteristic (ROC) analysis (for test optimization and finding optimal cut-off points), the area under curve (AUC) reached the following values for AcDi: i) DM without triage, AUC=0.843, ii) DM with triage I, AUC=0.866 and iii) DM with triage I and II, AUC=0.926. In the HSROC analysis, the AUC values for detection of AcDi were as follows; i) pooled clinical symptoms, AUC=0.540, ii) pooled clinical signs & tests, AUC=0.556 and iii) pooled DMs globally, AUC=0.853. In roccomp analysis for differences in AUC values: i) and iii) p<0.0001; between ii) and iii) p<0.0001. CONCLUSION: As confirmed by ROC and HSROC analysis, the new DMs with triage mode proved to be far superior in their DA for AcDi as compared to both symptoms and signs & tests. In the lack of earlier studies, these data report the first evidence that the DM including triage at an ED could improve the detection of AcDi.

Fecal Immunochemical Test (FIT) in Triage of Bleed-positive (Crab+) and Bleed-negative Colorectal Adenoma (Crab-) Patients in Colorectal Neoplasia Screening.

BACKGROUND/AIM: Fecal immunochemical tests (FITs) are sensitive and specific for detecting colorectal cancer (CRC), but their diagnostic accuracy (DA) in bleed-positive (CRAb+) and bleed-negative colorectal adenomas (CRAb-) has been rarely tested. PATIENTS AND METHODS: A total of n=506 patients were included in the study, each collecting 3 consecutive stool samples for analysis. The stool samples were analyzed by the ColonView FIT (CV) and Hemoccult SENSA tests. A total of 484/5,090 (9.5%) patients returned all 3 samples and were subjected to final analysis. Hierarchical summary receiver operating characteristic (HSROC) analysis with different cut-offs for hemoglobin/haptoglobin (Hb and Hb/Hp) complex was performed to assess the DA of CV. RESULTS: In the HSROC analysis, the AUC values were as follows: i) bleed-positive adenoma patients by visual analysis mode (VA), AUC=0.566, ii) bleed-positive adenoma patients by automatic analysis mode (AA), AUC=0.546, iii) bleed-negative adenoma patients by VA, AUC=0.534 and iv) bleed-negative adenoma patients by AA, AUC=0.589: In roccomp analysis, there were significant differences in AUC values between iii) and iv) p=0.045. CONCLUSION: When stratified by the 'blood in stool' (as b+ or b- endpoint), the DA of the CV test is quite similar for CRAb+ and CRAb-. However, of the two modes (VA/AA) of the CV test, the AA reading gives a slightly higher DA both CRAb+ and CRAb-.

Previous radiotherapy improves treatment responses and causes a trend toward longer time to progression among patients with immune checkpoint inhibitor-related adverse events.

BACKGROUND: Immune-related adverse events (irAEs) are frequently encountered by patients during immune checkpoint inhibitor (ICI) treatment and are associated with better treatment outcomes. The sequencing of radiotherapy (RT) and ICIs is widely used in current clinical practice, but its effect on survival has remained unclear. METHODS: In a real-world multicenter study including 521 patients who received ICI treatment for metastatic or locally advanced cancer, RT schedules and timing, irAEs, time to progression, overall survival, and treatment responses were retrospectively reviewed. RESULTS: Patients who received previous RT and developed irAE (RT +/AE +) had the best overall response rate (ORR 44.0%). The ORR was 40.1% in the RT -/AE + group, 26.7% in the RT -/AE - group and 18.3% in the RT + /AE - group (p < 0.001). There was a significantly longer time to progression (TTP) in the RT + /AE + group compared to the RT -/AE - and RT + /AE - groups (log rank p = 0.001 and p < 0.001, respectively), but the trend toward longer TTP in the RT + /AE + group did not reach statistical significance in pairwise comparison to that in the RT -/AE + group. Preceding RT timing and intent had no statistically significant effect on TTP. In a multivariate model, ECOG = 0 and occurrence of irAEs remained independent positive prognostic factors for TTP (HR 0.737; 95% CI 0.582-0.935; p = 0.012, and HR 0.620; 95% CI 0.499-0.769; p < 0.001, respectively). CONCLUSIONS: Better ORR and a trend toward longer TTP were demonstrated for patients with RT preceding ICI treatment and development of irAEs, which suggests that RT may boost the therapeutic effect of immunotherapy in patients with metastatic cancers.

A Possible Role of Interleukin-18 Binding Protein in Immune Regulation of Postoperative Pain: A Prospective Randomized Clinical Trial.

BACKGROUND/AIM: A possible role of interleukin-18 binding protein (IL-18BP) in immune regulation of pain and analgesics following surgery is rarely studied. The aim of this study was to investigate serum IL-18BP values in a cohort of laparoscopic cholecystectomy (LC) and minilaparotomy cholecystectomy (MC) patients and to establish their relationship with other cytokines and number of analgesic doses (NAD) of LC and MC patients postoperatively. PATIENTS AND METHODS: Blood levels of IL-18BP, six other interleukins (IL-18, IL-1ra, IL-6, IL-10, IL-1ß, and IL-8) and high-sensitivity C-reactive protein were measured before operation (PRE), immediately after operation (POP1), and six hours after operation (POP2) in 114 patients with cholelithiasis. RESULTS: Following surgery, the mean serum IL-18BP values correlated significantly to numeric rating scale (NRS) pain scores at 24 hours (r=0.194, p=0.009). In addition, the mean serum IL-18BP values correlated significantly to NAD (r=0.254, p<0.001). CONCLUSION: IL-18BP, a soluble antagonist of IL-18, correlates to NRS and NAD in LC and MC patients, which may support a possible role of IL-18BP in immune regulation of postoperative pain.

First RAND-36-Item Health Survey in Three-dimensional Laparoscopy Cholecystectomy: A Prospective Randomized Study.

BACKGROUND/AIM: National healthcare organizers require feedback from patients to improve medical treatment methods. Three-dimensional laparoscopy cholecystectomy (3D-LC) is a modern technique in surgery. However, there are no studies with patient feedback from validated questionnaires assessing the postoperative treatment results in 3D-LC. PATIENTS AND METHODS: Initially 200 patients with symptomatic cholelithiasis were randomized into 3D-LC or mini-laparotomy cholecystectomy (MC) groups. RAND-36-Item Health Survey was performed preoperatively and 4 weeks following surgery relating the survey scores between the 3D-LC and MC groups. RESULTS: Similar postoperative RAND-36 scores were reported for both groups preoperatively and at 4 weeks following surgery, and no significant differences in RAND-36 domains were shown. When the patients in both study groups were combined, Mental Health (p<0.001), Bodily Pain (p=0.01) and General Health (p=0.016) domain scores were significantly higher, indicating a significantly positive change in quality of life 4 weeks postoperatively, while those for the Role-Physical domain were significantly lower, indicating reduced physical activity during the 4 weeks following surgery. In comparison to the Finnish reference RAND-36 scores, scores at 4 weeks were significantly higher for the Mental Health domain (MC group, p<0.001 and 3D-LC group, p=0.001) whilst scores were significantly lower in four other domains: Physical Functioning, Social Functioning, Bodily Pain and Role-Physical. CONCLUSION: This study shows, for the first time using the RAND-36-Item Health Survey, relatively similar short-term outcomes in patients 4 weeks following cholecystectomy by 3D-LC and MC. Although scores for three RAND-36 domains were significantly higher postoperatively, indicating a significantly positive change in quality of life, a longer follow-up after cholecystectomy is needed for final conclusions to be drawn.

Diagnostic Accuracy of Fecal Immunochemical Test (FIT) in Bleed-positive and Bleed-negative Colorectal Cancer (CRC) Among a Cohort of 5,090 Subjects who Participated in the Colorectal Neoplasia (CRN) Screening in Brazil.

BACKGROUND/AIM: This study assessed the diagnostic accuracy (DA) of fecal immunochemical test (FIT) ColonView (CV) and guaiac-based fecal occult blood test (HemoccultSENSA) among bleed-positive (history or signs of intestinal bleeding) and bleed-negative participants (no history or signs of intestinal bleeding) (n=5,090) in colorectal neoplasia (CRN) screening in Brazil. PATIENTS AND METHODS: The eligible patients for the study (n=506) collected three consecutive stool samples, to be analyzed by both assays (CV, SENSA). Finally, 421/5090 (8.3%) patients returned both samples, which were subjected to final analysis. Receiver operating characteristic (ROC) analysis with different cut-offs was performed to assess the DA. RESULTS: The area under curve (AUC) values for i) visually analyzed (VA) CV for bleed-positive CRC, ii) automatically analyzed (AA) CV for bleed-positive CRC, iii) VA CV for bleed-negative CRC, and iv) AA CV for bleed-negative CRC as endpoints were as follows: i) AUC=0.864, ii) AUC=0.933, iii) AUC=0.836, and iv) AUC=0.892. In roccomp analysis, the differences in AUC values were: between i) and ii) p=0.068; between i) and iii) p=0.497; between i) and iv) p=0.488; between ii) and iii) p=0.0058; between ii) and iv) p=0.229; and between iii) and iv) p=0.138. CONCLUSION: This is the first investigation where two modes of CV test, VA, and AA, for bleed-positive and bleed-negative CRC patients were used as the endpoint. The AA reading of the CV test showed higher DA in bleed-positive than in bleed-negative CRC patients.

Blood-Brain Barrier Disruption (BBBD)-Based Immunochemotherapy for Primary Central Nervous System Lymphoma (PCNSL), Early Results of a Phase II Study.

Primary central nervous system lymphoma is a rare but aggressive brain malignancy. It is associated with poor prognosis even with the current standard of care. The aim of this study was to evaluate the effect and tolerability of blood-brain barrier disruption treatment combined with high-dose treatment with autologous stem cell transplantation as consolidation on primary central nervous system lymphoma patients. We performed a prospective phase II study for 25 patients with previously untreated primary central nervous system lymphoma. The blood-brain barrier disruption treatment was initiated 3-4 weeks after the MATRix regimen using the previously optimized therapy protocol. Briefly, each chemotherapy cycle included two subsequent intra-arterial blood-brain barrier disruption treatments on days 1 and 2 via either one of the internal carotid arteries or vertebral arteries. Patients received the therapy in 3-week intervals. The treatment was continued for two more courses after achieving a maximal radiological response to the maximum of six courses. The complete treatment response was observed in 88.0% of the patients. At the median follow-up time of 30 months, median progression-free and overall survivals were not reached. The 2-year overall and progression-free survival rates were 67.1% and 70.3%, respectively. Blood-brain barrier disruption treatment is a promising option for primary central nervous system lymphoma with an acceptable toxicity profile.

Impact of minimal invasive extracorporeal circulation on perioperative intravenous fluid management in coronary artery bypass surgery.

OBJECTIVE: Compare the use of blood products and intravenous fluid management in patients scheduled for coronary artery bypass surgery and randomized to minimal invasive extracorporeal circulation (MiECC) and conventional extracorporeal circulation (CECC). METHODS: A total of 240 patients who were scheduled for their first on-pump CABG, were randomized to MiECC or CECC groups. The study period was the first 84 hours after surgery. Hemoglobin <80 g/l was used as transfusion trigger. RESULTS: Red blood cell transfusions intraoperatively were given less often in the MiECC group (23.3% vs 9.2%, p = 0.005) and the total intravenous fluid intake was significantly lower in the MiECC group (3300 ml [2950-4000] vs 4800 ml [4000-5500], p < 0.001). Hemoglobin drop also was lower in the MiECC group (35.5 ± 8.9 g/l vs 50.7 ± 9 g/l, p < 0.001) as was hemoglobin drop percent (25.3 ± 6% vs 35.3 ± 5.9%, p < 0.001). Chest tube drainage output was higher in the MiECC group (645 ml [500-917.5] vs 550 ml [412.5-750], p = 0.001). Particularly, chest tube drainage in up to 600 ml category, was in benefit of CECC group (59.1% vs 40.8%, p = 0.003). ROC curve analysis showed that patients with hemoglobin level below 95 g/l upon arrival to intensive care unit was associated with increased risk of developing postoperative atrial fibrillation (POAF) (p = 0.002, auc = 0.61, cutoff <95, sensitivity = 0.47, positive predictive value = 0.64). CONCLUSION: MiECC reduced the intraoperative need for RBC transfusion and intravenous fluids compared to the CECC group, also reducing hemoglobin drop compared to the CECC group in CABG surgery patients. Postoperative hemoglobin drop was a predictor of POAF.
