Učinak mamografskog postupka na serumske razine upalnih i/ili tumorskih biljega

Mammography is one of the gold standard screening tests for breast cancer. The effects of mammography procedure on blood parameters are not known. This study aimed to investigate whether the procedure-associated breast compression affects the widely and simultaneously performed blood measurements of C-reactive protein (CRP), carcinoembryonic antigen (CEA), and cancer antigen (CA) 15-3. According to breast ultrasound examination results, participants were divided into 3 groups as follows: group 1 (participants with breast mass size ≥20.0 mm, n=48); group 2 (participants with breast mass size <20.0 mm, n=17); and group 3 (participants with no breast mass, n=23). In groups 1 and 2, on the day of the mammographic imaging study, serum CRP, CEA, and CA 15-3 levels were measured before and after the imaging study. Participants in group 3 had their blood parameters measured without mammography and/or any breast compression. Post-mammography blood measurements displayed a significant increase in serum CRP levels, and a significant decrease in serum CEA and CA 15-3 levels in group 1 (in comparison with the same day pre-mammography blood sampling levels; p<0.05 all). Although pre-mammography serum CEA levels in group 1 participants were significantly higher than those in group 2 and 3 participants, this significant elevation became nonsignificant at post-mammography measurements (p0.05, respectively). On the day of the mammographic imaging study, the optimal time of blood sampling for testing CRP, CEA and CA 15-3 levels in persons with a breast mass is before, but not after the mammographic imaging procedure. This issue requires additional detailed studies.Mamografija je jedan od ‘zlatnih’ standardnih testova probira za rak dojke. Učinci mamografskog postupka na krvne parametre nisu poznati. Cilj ovog istraživanja bio je ispitati djeluje li kompresija dojke povezana s ovim postupkom na često i istodobno izvođena mjerenja C-reaktivnog proteina (CRP), karcinoembrijskog antigena (CEA) i karcinom antigen (CA) 15-3 u krvi. Ispitanice su podijeljene u 3 skupine prema rezultatima ultrazvučnog pregleda dojki: 1. skupina (ispitanice s masom u dojci ≥20,0 mm, n=48); 2. skupina (ispitanice s masom u dojci <20,0 mm, n=17); 3. skupina (ispitanice bez mase u dojci, n=23). U 1. i 2. skupini serumske razine CRP, CEA i CA 15-3 mjerene su prije i nakon mamografskog postupka. Kod ispitanica 3. skupine krvni parametri mjereni su bez mamografije i/ili bilo kakve kompresije dojke. Mjerenja provedena nakon mamografije pokazala su značajan porast serumskih razina CRP i značajan pad serumskih razina CEA i CA-15-3 u 1. skupini u usporedbi s razinama tih parametara zabilježenim istoga dana prije mamografije (p<0,05 sve). Iako su razine CEA u serumu prije mamografije bile značajno više u 1. skupini u usporedbi s 2. i 3. skupinom, značajnost tog porasta izgubila se kod mjerenja nakon mamografije (p0,05). Dakle, u danu kad je zakazana mamografija optimalno vrijeme za uzorkovanje krvi za mjerenje razina CRP, CEA i CA 15-3 kod osoba s masom u dojci je prije, a ne poslije mamografskog postupka. Ovo pitanje zahtijeva daljnje podrobne studije

Clinical Significance of Serum NEDD9 Levels in Patients with Pancreatic Cancer

Introduction: Pancreatic cancer (PC) is a lethal malignancy. Various diagnostic, predictive, and prognostic biomarkers have been evaluated. This study was conducted to investigate the serum levels of neural precursor cell expressed developmentally downregulated protein 9 (NEDD9) in patients with PC and the relationship between tumor progression and known prognostic parameters. Materials and Methods: Serum samples were obtained on first admission before any treatment. Serum NEDD9 levels were determined using enzyme-linked immunosorbent assay (ELISA). Age- and sex-matched healthy controls were included in the analysis. Results: In a three year period, 32 patients with a pathologically-confirmed diagnosis of PC were enrolled in this study. The median age at diagnosis was 61 years, range 38 to 84 years; the majority of the patients in the group were men (n = 20, 62.5%). The tumor was located in the head of pancreas in 21 (65.6%) patients. Forty-one percent of 17 metastatic patients who received palliative CTx (chemotherapy) were CTx-responsive. The baseline serum NEDD9 levels were significantly higher in patients with PA than in the control group (p = 0.03). Median OS of the whole group were 27 +/- 7.3 weeks. Alcohol intake, performance status, and LDH levels were found to be significant prognostic factors (p = 0.006, p < 0.001, and p < 0.001, respectively). However, serum NEDD9 levels had no significantly effect on progression free survival (PFS) and overall survival (OS) (p = 0.71 and p = 0.58, respectively). Conclusions: NEDD9 is identified as a secretory biomarker for PC but it has no prognostic role

Plasma presepsin in determining gastric leaks following bariatric surgery

Background: To be able to prevent morbid obesity in the long-term, laparoscopic sleeve gastrectomy (LSG) is one of the most effective surgical interventions. However, leakage and bleeding from the stapler line are significant complications. The aim of this study was to determine the role of the levels of plasma presepsin in the detection of stapler leakage

The marker C-reactive protein is helpful in monitoring the integrity of anastomosis: plasma calprotectin

BACKGROUND: Despite improved surgical techniques and materials, anastomotic leakage is a big problem for surgeons. The most frequently used laboratory parameters is leukocyte (white blood cell) and C-reactive protein (CRP). Availability of plasma calprotectin with CRP to detect anastomotic leakage was studied

The Rate of Idiopathic Spontaneous Pneumoperitoneum is 2.36%

Objective: Pneumoperitoneum often occurs following a visceral perforation, often seen with peritonitis, and requires urgent surgical intervention. Non-surgical spontaneous pneumoperitoneum (not associated with organ perforation) is a rare condition caused by intrathoracic, intraabdominal, gynecologic, iatrogenic, and other causes, and may be treated conservatively. Spontaneous idiopathic pneumoperitoneum is not caused by visceral perforation, the cause may be extra-abdominal origin and sometimes cannot be determined

Measurement of Advanced Glycation End Products Could Be Used as an Indicator of Unhealthy Nutrition for Colorectal Cancer Risk

The main culprit behind most cancers is the accumulation of reactive oxygen species. Glyoxal (GO) and methylglyoxal (MGO) are reactive intermediates created by food processing and they are precursors of advanced glycation end products (AGE) that cause glycative stress. We aimed to evaluate the relationship between AGE levels of healthy volunteers and treatment-naive patients diagnosed with colorectal cancer. The study consisted of patients diagnosed with colorectal cancer and healthy volunteers who underwent routine colonoscopy. The study was conducted with a total of 42 cases, 47.6% (n = 20) female. The ages of the participants in the study ranged from 41 to 82 years, and the mean was 60.57 +/- 10.78 years. The GO and MGO values of the patient group were found to be significantly higher than those of the control group (p = 0.007, p = 0.001, respectively). The risk of colorectal cancer was 22 and 57 times higher in individuals with GO and MGO values above 1.25 mu g/mL and 0.0095 mu g/mL, respectively. The blood AGE level is closely related to diet, and it can be decreased through the appropriate improvement of diet. Thus, the measurement of AGE can be used to predict whether a person's nutrition is healthy or unhealthy and prevent increased risk of colorectal cancer

Plasma calprotectin level: usage in distinction of uncomplicated from complicated acute appendicitis

Background: The aim of this study was to identify the diagnostic role of plasma calprotectin value for a distinction of presence acute appendicitis and the indifference of uncomplicated from complicated acute appendicitis
