RESUMO
Background and Objectives: It has been suggested that intense feelings of fear/anxiety and significant patient concerns may affect the perioperative course. Those findings emphasize the importance of surgical patients' preoperative feelings. Still, current knowledge in this area is based on a limited number of studies. Thus, we think that there is a need to further explore patients' preoperative fears, better characterize risk factors and reasons for their occurrence, and evaluate patients' perspectives associated with anesthesia. Materials and Methods: A total of 385 patients undergoing vascular surgery were preoperatively interviewed using a questionnaire that included demographics and questions related to patients' fears and perceptions of anesthesia. Statistical analyses included descriptive statistics, Pearson's χ2 and McNemar tests, and multivariate ordinal logistic regression. Results: The main causes of patients' preoperative fear were surgery (53.2%), potential complications (46.5%), and anesthesia (40%). Female sex was a predictor of surgery and anesthesia-related fear (OR = 3.07, p = 0.001; OR = 2.4, p = 0.001, respectively). Previous experience lowered the fear of current surgery (OR = 0.65, p = 0.031) and anesthesia (OR = 0.6, p = 0.017). Type of surgery, type of anesthesia, educational and socioeconomic status, and personal knowledge of an anesthesiologist affected specific anesthesia-related fears. Over 25% of patients did not know that an anesthesiologist is a physician, and only 17.7% knew where anesthesiologists work. Level of education and place of residence influenced patients' perceptions of anesthesia. Conclusions: Anesthesia-related fears are affected by the type of surgery/anesthesia, experience with previous surgery, and personal knowledge of an anesthesiologist. Women, patients with lower education levels, and patients with poorer socioeconomic status are at higher risk of developing those fears. The perception of anesthesiologists is inadequate, and knowledge of anesthesia is poor. Promotion of patient education regarding anesthesia is needed to alleviate those fears and increase understanding of anesthesia.

OBJECTIVE: Thyroid dysfunction is a common cause of atrial fibrillation (AF). Incidence of AF is high in patients with both expressed and subclinical hyperthyroidism. The aim of our study was to determine the incidence and predictors of new onset atrial fibrillation (NOAF) in euthyroid patients undergoing thyroid surgery. SUBJECT AND METHODS: The study included 1,252 euthyroid patients with American Society of Anesthesiologists (ASA) physical status ASA 2 and ASA 3, who were 18 years and older and were in sinus rhythm. Patients without comorbidity and patients with persistent AF were excluded. We investigated the influence of the following preoperative characteristics on the occurrence of NOAF: age, sex, body mass index, ASA score, admission diagnoses, and comorbidity. We noted the influence of difficult intubation of trachea, type and duration of surgery, and time under general anaesthesia. Univariate and multivariate logistic regression were used to determine predictors of occurrence of NOAF. RESULTS: NOAF was noted in 0.72% of patients. Patients with NOAF were older (63.11 vs. 56.81 years) than patients without NOAF, but this was not statistically significant. Significantly more patients from the NOAF group had preoperative heart rhythm disturbance and a history of angina pectoris, in contrast to patients without registered NOAF (p = 0.001; p = 0.017). Multivariate analysis showed that a history of heart rhythm disturbance was an independent predictor of NOAF. CONCLUSIONS: Incidence of NOAF during thyroid surgery is similar to the other type of surgery, if the values of thyroid hormones are normal.

BACKGROUND: The aim was to determine the effect of regional anesthesia (RA) on postoperative vital functions in contrast to general endotracheal anesthesia (GEA) after the cesarean section. METHODS: Prospective cohort study included consecutive term pregnant women delivered by cesarean section (GEA, n = 284; RA, n = 249). RESULTS: Higher levels of blood pressure and heart rate, as well as lower levels of pulse oximetry were found for GEA in contrast to RA (p < 0.001). The application of RA presented less side-effects (p < 0.05). CONCLUSIONS: RA for cesarean section should be preferred when balancing the risks and benefits for the mother and fetus.

BACKGROUND: Preoperative anxiety is associated with increased morbidity and/or mortality in surgical patients. This study investigated the incidence, predictors, and association of preoperative anxiety with postoperative complications in vascular surgery. METHODS: Consecutive patients undergoing aortic, carotid, and peripheral artery surgery, under general and regional anesthesia, from February until October 2019 were included in a cross-sectional study. Anesthesiologists assessed preoperative anxiety using a validated Serbian version of the Amsterdam Preoperative Anxiety and Information Scale. Patients were divided into groups with low/high anxiety, both anesthesia- and surgery-related. Statistical analysis included multivariate linear logistic regression and point-biserial correlation. RESULTS: Of 402 patients interviewed, 16 were excluded and one patient refused to participate (response rate 99.7%). Out of 385 patients included (age range 39-86 years), 62.3% had previous surgery. High-level anesthesia- and surgery-related anxieties were present in 31.2 and 43.4% of patients, respectively. Independent predictors of high-level anesthesia-related anxiety were having no children (OR = 0.443, 95% CI: 0.239-0.821, p = 0.01), personal bad experiences with anesthesia (OR = 2.294, 95% CI: 1.043-5.045, p = 0.039), and time since diagnosis for ≥ 4 months (OR = 1.634, 95% CI: 1.023-5.983, p = 0.04). The female sex independently predicted high-level surgery-related preoperative anxiety (OR = 2.387, 95% CI: 1.432-3.979, p = 0.001). High-level anesthesia-related anxiety correlated with postoperative mental disorders (rpb = 0.193, p = 0.001) and pulmonary complications (rpb = 0.104, p = 0.042). Postoperative nausea (rpb = 0.111, p = 0.03) and postoperative mental disorders (rpb = 0.160, p = 0.002) correlated with high-level surgery-related preoperative anxiety. CONCLUSIONS: Since preoperative anxiety affects the postoperative course and almost every third patient experiences anxiety preoperatively, routine screening might be recommended in vascular surgery.

Background and Objectives: Pain during and after the procedure remains the leading concern among women undergoing cesarean section. Numerous studies have concluded that the type of anesthesia used during a cesarean section undoubtedly affects the intensity and experience of pain after the operation. Materials and Methods: This prospective cohort study was conducted at the Clinic for Gynecology and Obstetrics, Clinical Center "Dragisa Misovic-Dedinje", Belgrade, Serbia. Patients at term pregnancy (37-42 weeks of gestation) with an ASA I score who delivered under general (GEA) or regional anesthesia (RA) by cesarean section were included in the study. Following the procedure, we assessed pain using the Serbian McGill questionnaire (SF-MPQ), Visual Analogue Scale (VAS) and the pain attributes questionnaire at pre-established time intervals of 2, 12, and 24 h after the procedure. Additionally, time to patient's functional recovery was noted. We also recorded the time to the first independent mobilization, first oral intake, and lactation establishment. Results: GEA was performed for 284 deliveries while RA was performed for 249. GEA had significantly higher postoperative sensory and affective pain levels within intervals of 2, 12, and 24 h after cesarean section. GEA had significantly higher postoperative VAS pain levels. On pain attribute scale intensity, GEA had significantly higher postoperative pain levels within all intervals. Patients who received RA had a shorter time to first oral food intake, first independent mobilization, and faster lactation onset in contrast to GEA. Conclusions: The application of RA presented superior postoperative pain relief, resulting in earlier mobilization, shorter time to first oral food intake, and faster lactation onset in contrast to GEA.

OBJECTIVES: Preoperative anxiety is common and might affect surgical treatment outcomes. The aim was to translate and validate the Serbian version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS). METHODS: Following translation and initial evaluation, the Serbian version (S-APAIS) was administered to 385 patients. Internal consistency, construct validity, prognostic criteria validity, and concurrent validity between S-APAIS and Visual Analogue Scale for Anxiety (VAS-A) were evaluated. RESULTS: Factor analysis revealed two factors: APAIS-anesthesia (items 1, 2, 3) and APAIS-procedure (items 4, 5, 6). The whole scale, APAIS-anesthesia, and APAIS-procedure subscales showed an adequate level of internal consistency (Cronbach's αs: 0.787, 0.806, and 0.805, respectively). High concurrent validity was observed between APAIS-anesthesia and VAS-A (ρ = 0.628, p < .001). A moderate correlation was found between APAIS-procedure and VAS-A scale (ρ = 0.537, p < .001). At the cut-off point of 9, the area under the curve (AUC) of APAIS-anesthesia was 0.815 (95% CI: 0.77-0.85, p < .001). For the APAIS-procedure, AUC was 0.772 (95% CI: 0.73-0.81, p < .001) at the cut-off point of 8. CONCLUSION: The structure of S-APAIS substantially differs from the original and allows separate measurement of anesthesia- and procedure-related anxieties. S-APAIS is a comprehensive, valid, and reliable instrument for the measurement of preoperative anxiety.

BACKGROUND: Primary aldosteronism (PA) is associated with increased prevalence of metabolic disorders (impaired glucose and lipid metabolism and insulin resistance), but also with more frequent cardiovascular, renal and central nervous system complications. METHODS: Biochemical and clinical parameters were retrospectively analysed for 40 patients with PA caused by aldosterone-producing adenoma (APA) and compared to the control groups of 40 patients with nonfunctioning adrenal adenoma (NFA) and essential hypertension (HT), and 20 patients with adrenal Cushing syndrome (CS) or subclinical CS (SCS). RESULTS: Systolic, diastolic and mean arterial blood pressures were significantly higher in the PA group (p=0.004; p=0.002; p=0.001, respectively) than in NFA+HT group. PA patients had longer hypertension history (p=0.001) than patients with hypercorticism and all had hypokalaemia. This group showed the smallest mean tumour diameter (p<0.001). The metabolic syndrome was significantly less common in the PA group (37.5% vs. 70% in CS+SCS and 65% in NFA+HT group; p=0.015), although there was no significant difference in any of the analysed metabolic parameters between groups. PA group was found to have the most patients with glucose intolerance (81.8%), although the difference was not significant. The mean BMI for all three groups was in the overweight range. Patients with PA had higher microalbuminuria and a higher tendency for cardiovascular, renal and cerebrovascular events, but the difference was not significant. CONCLUSIONS: Our results support the importance of the early recognition of primary aldosteronism on the bases of clinical presentation, as well as an increased screening intensity.
RESUMO
PURPOSE: The purpose of this study was to compare two groups in postoperative recovery, whether there were any complications and whether the length of their hospital stay differed. One group received intraoperatively a combination of crystalloids and a small colloid dose, while the other group received only the crystalloids intraoperatively. METHODS: This randomized prospective study included 80 patients with colorectal cancer prepared for major elective colorectal surgery. The patients were randomly assigned to either the control group (CG) which received only crystalloid solutions intraoperatively or to the research group (RG) which received a combination of colloid and crystalloid solutions. Regional and general endotracheal anesthesia techniques were combined in all patients. Goal-directed fluid therapy was administered to patients in both groups. After extubation, patients were transferred in the Intensive Care Unit (ICU). We measured the administered fluids, fluid balance, the volume of received red packed cells (RPC) and fresh frozen plasma (FFP). Recorded were the first bowel movement, the first flatus, the tolerance on oral food, complications by Clavian-Dindo classification, days of patient's recovery delay in the ICU, Surgery Department (SD) and the total length of hospital stay (LOS). RESULTS: Statistically significant differences were present in all parameters of postoperative recovery. RG patients showed better results relative to the CG patients. RG patients were faster in restoring bowel movement and peristalsis, get the first postoperative stool and re-acquire oral food tolerance. According to the Clavian-Dindo classification of complications, no significant difference between these two groups was noted. CONCLUSIONS: Goal-directed colloid-crystalloid therapy significantly improved postoperative recovery.

PURPOSE: To determine whether there was a correlation between the type of administered infusion solutions intraoperatively with the quantity of administered infusion solutions, differences in values of cardiac output (CO) and cardiac index (CI) and need to use vasopressors and inotropes, between control and research groups. METHODS: This randomized prospective study included 55 patients with colorectal cancer. Subjects in the control group received only crystalloid solutions intraoperatively and postoperatively. The patients in the research group received a combination of colloid in dosage of 10mg/kg and crystalloid solutions. Patients in both groups were given goal directed fluid therapy. RESULTS: The control group received a significantly larger amount of crystalloid solution per kg of body weight during the entire surgical operation, in comparison with the volume of crystalloids in the research group (mean±SD 50.78±28.13 vs. 31.63±25.60 respectively, p=0.01). During the first hour of the surgery, the control group received a larger quantity of fluid in comparison with the research group (mean±SD 31.14±9.78 vs. 22.17±9.92 respectively, p=0.001). From the beginning of anesthesia until 6th postoperative hr the values of CI were significantly higher in the research group in comparison with the control group. CONCLUSIONS: Goal directed fluid therapy with colloids, followed by crystalloids during surgery, decreased the total intraoperative fluid volumes, and provided higher values of CI intraoperatively which were also maintained postoperatively.

Intraoperative bradycardia (IOB) is one of the most common cardiac arrhythmias observed in clinical anaesthetic practice. Controlled hypotension, as a strategy of lowering patient's blood pressure during anesthesia has been practiced for decades in head and neck surgery. The aim of our study was to determine the incidence and the risk factors for intraoperative bradycardia in maxillofacial, ear, nose and throat surgery, as well as to determine whether controlled hypotension affects the occurrence of IOB. The retrospective study included 2304 patients who underwent maxillofacial, ear, nose or throat surgery. We studied the influence of: sex, age, comorbidity, type of surgery, duration of anesthesia and controlled hypotension on the occurrence of IOB. IOB was registered in 473 patients (20.5%). Patients with controlled hypotension had IOB significantly more often than patients without controlled hypotension (33.9 vs 15.1%) (p = 0.000). The significant predictors of IOB were: age (OR = 1.158; 95% CI = 1.068-1.256; p = 0.000), sex (OR = 0.786; 95% CI = 0.623-0.993; p = 0.043), ischemic heart disease (OR = 2.016; 95% CI = 1.182-3.441; p = 0.010); ear surgery (OR = 1.593; 95% CI = 1.232-2.060; p = 0.000), anesthesia duration, (OR = 1.006; 95% CI = 1.004-1.007; p = 0.000) and controlled hypotension (OR = 2.204; 95% CI = 1.761-2.758; p = 0.000). IOB is common in maxillofacial, ear, nose and throat surgery, particularly in male, older age and patients with ishemic heart disease. The ear surgery, longer anesthesia duration and controlled hypotension raise the risk for occurrence of IOB.

OBJECTIVE: To investigate the incidence and identify risk factors for the occurrence of intraoperative hypertension (IOH) during surgery for primary hyperparathyroidism (pHPT). SUBJECTS AND METHODS: The study included 269 patients surgically treated between January 2008 and January 2012 for pHPT. IOH was defined as an increase in systolic blood pressure ≥20% compared to baseline values which lasted for 15 min. The investigated influence were demographic characteristics, surgical risk score related to physical status (based on the American Society of Anesthesiologists [ASA] classification), comorbidities, type and duration of surgery, and duration of anesthesia on IOH occurrence. The investigated factors were obtained from the patients' medical history, anesthesia charts, and the daily practice database. Logistic regression analysis was done to determine the predictors of IOH. RESULTS: Of the 269 patients, 153 (56.9%) had IOH. Based on the univariate analysis, age, body mass index, ASA status, duration of anesthesia, and preoperative hypertension were risk factors for the occurrence of IOH. Multivariate analysis showed that independent predictors of IOH were a history of hypertension (OR = 2.080, 95% CI: 1.102-3.925, p = 0.024) and age (OR = 0.569, 95% CI: 0.360-0.901, p = 0.016). CONCLUSION: In this study, a high percentage (56%) of the patients developed IOH during surgery for pHPT, which indicates that special attention should be paid to these patients, especially to the high-risk groups: older patients and those with a history of hypertension. Further, this study showed that advanced age and hypertension as a coexisting disease prior to parathyroid surgery were independent risk factors for the occurrence of IOH.

BACKGROUND: The objective of our study was to determine the serum concentrations of protein S100B and neuron specific enolase (NSE) as well as their ability and accuracy in the prediction of early neurological outcome after a traumatic brain injury. METHODS: A total of 130 polytraumatized patients with the associated traumatic brain injuries were included in this prospective cohort study. Serum protein S100B and NSE levels were measured at 6, 24, 48 and 72 hours after the injury. Early neurological outcome was scored by Glasgow Outcome Scale (GOS) on day 14 after the brain injury. RESULTS: The protein S100B concentrations were maximal at 6 hours after the injury, which was followed by an abrupt fall, and subsequently slower release in the following two days with continual and significantly increased values (p<0.0001) in patients with poor outcome. Secondary increase in protein S100B at 72 hours was recorded in patients with lethal outcome (GOS 1). Dynamics of NSE changes was characterized by a secondary increase in concentrations at 72 hours after the injury in patients with poor outcome. CONCLUSION: Both markers have good predictive ability for poor neurological outcome, although NSE provides better discriminative potential at 72 hours after the brain injury, while protein S100B has better discriminative potential for mortality prediction.
RESUMO
The hyomental distance ratio (HMDR) is the ratio between the hyomental distance (HMD) (the distance between the hyoid bone and the tip of the chin) at the extreme of head extension (HMDe) and the one in the neutral position (HMDn). The objective of the study was to examine the predictive value, sensitivity, and specificity of HMDe, HMDn, and HMDR in predicting difficult endotracheal intubation (DI). A prospective study included 262 patients that underwent elective surgical operations. The following parameters were observed as possible predictors of DI: HMDR, HMDe, HMDn, Mallampati score, and body mass index (BMI). The cut-off points for the DI predictors were HMDe <5.3 cm, HMDn ≤5.5 cm, and HMDR ≤1.2. The assessment that DI existed was made by the anesthesiologist while performing laryngoscopy by applying the Cormack-Lehane classification. DI was present in 13 patients (5%). No significant difference was observed in the frequency of DI with regard to the sex, age, and BMI of the patients. Our research indicated HMDR as the best predictor of DI with a sensitivity of 95.6% and specificity of 69.2%. HMDR can be used in the everyday work of anesthesiologists because HMDR values ≤1.2 may reliably predict DI.

Difficult tracheal intubation (DI) is more common in thyroid than in other surgical branches due to thyromegaly. Proper preoperative airway evaluation is necessary in order to reduce the potential numerous complications. The study examined the incidence of DI in thyroid surgery and the influence of tracheal dislocation and other risk factors on DI. A prospective study was conducted on 2379 patients who underwent thyroidectomy at the Center for Endocrine Surgery, Clinical Center of Serbia, from 2007 to 2012. Patients were divided into groups with (n = 162) and without DI (n = 2217). Besides tracheal dislocation, another 13 risk factors contained in 13 screening tests and three additional factors of gender, age and diagnosis were defined. The incidence of DI in our study was 6.81%. The presence of tracheal dislocation was statistically significant, but not an independent predictor of DI. The diagnosis, large circumference and small neck length, previous DI, recessive mandible, tooth characteristics and oral anomalies were the most significant and independent predictors of DI. Neck circumference and small neck length had highest sensitivity. Previous DI had highest specificity. Thyromegaly, if causing tracheal dislocation and/or stenosis, represents a significant DI predictor, not individually, but in combination with other factors.

Sepsis-associated acute kidney injury (SA-AKI) severely impacts morbidity and mortality in surgical patients with sepsis. Matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) have an important role in pathophysiology of sepsis but they have been unexplored in SA-AKI. We aimed to investigate the role of MMP-9 and TIMP-1 in septic surgical patients with SA-AKI and to evaluate them as diagnostic biomarkers of SA-AKI. This prospective observational study compared 53 major abdominal surgery patients with sepsis divided into SA-AKI (n = 37) and non-SA-AKI (n =16) group to 50 controls without sepsis matched by age, gender, comorbidities and type of surgery. Blood and urine samples from septic patients were collected on admission to ICU and 24, 48, 72 and 96 h later and once from the controls. The levels of MMP-9, TIMP-1, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1, urea and creatinine were measured. MMP-9/TIMP-1 ratio and disease severity scores, such as Sequential Organ Failure Assessment (SOFA), were calculated. Septic patients with SA-AKI had higher serum TIMP-1 levels and lower serum MMP-9 levels and lower MMP-9/TIMP ratio, compared to septic patients without SA-AKI and controls. The levels of these biomarkers did not change significantly over time. MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio correlated with urea, creatinine, NGAL, and SOFA scores. Moreover, using the area under ROC curve, we showed that TIMP-1 and MMP-9/TIMP-1 ratio, but not MMP-9, were good diagnostic biomarkers of SA-AKI. We report for the first time the potential diagnostic value of TIMP-1 and MMP-9/TIMP-1 ratio in SA-AKI.

AIMS: To provide updated knowledge regarding the airway management and the possibility of difficult intubation in diabetic patients. MATERIALS AND METHODS: We preformed a systematic literature review of the English language literature, published over the past 10 years which deals with this subject. RESULTS: The vast majority of the modern literature data supports the fact that diabetic population has higher risk for difficult intubation occurrence. The most important characteristics of diabetic patients that are considered to be contributing factors for the difficult intubation are obesity, increased neck circumference and stiff joint syndrome. CONCLUSION: A special attention and thorough preoperative preparation should be given to patients with diabetes. In order to predict and prevent difficult intubation in these patients, further studies are needed to investigate this issue closely.

BACKGROUND: Graves' disease represents an autoimmune disease of the thyroid gland where surgery has an important role in its treatment. The aim of our paper was to analyze the results of surgical treatment, the frequency of microcarcinoma and carcinoma, as well as to compare surgical complications in relation to the various types of operations performed for Graves' disease. METHODS: We analysed 1432 patients (221 male and 1211 female) who underwent surgery for Graves' disease at the Centre for Endocrine Surgery in Belgrade during 15 years (1996-2010). Average age was 34.8 years. Frequency of surgical complications within the groups was analyzed with nonparametric Fisher's test. RESULTS: Total thyroidectomy (TT) was performed in 974 (68%) patients, and Dunhill operation (D) in 221 (15.4). Carcinoma of thyroid gland was found in 146 patients (10.2%), of which 129 (9%) were a microcarcinoma. Complication rates were higher in the TT group, where there were 31 (3.2%) patients with permanent hypoparathyroidism, 9 (0.9%) patients with unilateral recurrent nerve paralysis and 10 (1.0%) patients with postoperative bleeding. Combined complications, such as permanent hypoparathyroidism with bleeding were more common in the D group where there were 2 patients (0,9%), while unilateral recurrent nerve paralysis with bleeding was more common in the TT group where there were 3 cases (0,3%). CONCLUSIONS: Frequency of complications were not significantly statistically different in relation to the type of surgical procedure. Total thyroidectomy represents a safe and efficient method for treating patients with Graves' disease, and it is not followed by a greater frequency of complications in relation to less extensive procedures.

Background. Anaplastic thyroid cancer (ATC) is one of the tumors with the shortest survival in human medicine. Aim. The aim was to determine the importance of age in survival of patients with ATC. Material and Methods. We analyzed the data on 150 patients diagnosed with ATC in the period from 1995 to 2006. The Kaplan-Meier method and log-rank test were used to determine overall survival. Prognostic factors were identified by univariate and multivariate Cox regression analysis. Results. The youngest patient was 35 years old and the oldest was 89 years old. According to univariate regression analysis, age was significantly associated with longer survival in patients with ATC. In multivariate regression analysis, patients age, presence of longstanding goiter, whether surgical treatment is carried out or not, type of surgery, tumor multicentricity, presence of distant metastases, histologically proven preexistent papillary carcinoma, radioiodine therapy, and postoperative radiotherapy were included. According to multivariate analysis, besides surgery (P = 0.000, OR = 0.43, 95% CI = 0.29-0.63), only patients age (P = 0.023, OR = 0.68, 95% CI = 0.49-0.95) was independent prognostic factor of favorable survival in patients with ATC. Conclusion. Age is a factor that was independently associated with survival time in ATC. Anaplastic thyroid cancer has the best prognosis in patients younger than 50 years.
RESUMO
INTRODUCTION: State of severe oxidative stress is encountered in sepsis. Paraoxonase 1 (PON1) protects against oxidative stress but also undergoes inactivation upon that condition. We investigated PON1 activity in surgical patients with sepsis in relation to oxidative stress status, inflammation, disease severity, and survival. METHODS: Prospective observational study. Sixty-nine surgical patients with sepsis were compared to 69 age/sex matched healthy controls. PON1 paraoxonase and diazoxonase activities, selected biochemical, hematological and oxidative stress parameters were measured on admission to ICU and 24, 48, 72, and 96 hours later. Disease severity scores were calculated daily. RESULTS: Septic patients had significantly lower PON1 activities compared to control group at all time points. PON1 activities had good capacity to differentiate septic patients from healthy controls. Low PON1 activities were associated with higher disease severity scores and higher risk of death. Correlation between PON1 activity and markers of inflammation failed to reach significance. Decrease in PON1 activity was correlated with an increase in reducing components in plasma. CONCLUSION: Our study demonstrated lower PON1 activity in surgical patients with sepsis compared to healthy controls. PON1 activity also reflected severity of the disease. Low PON1 activity was associated with higher mortality of surgical patients with sepsis.

AIMS AND BACKGROUND: Thyroid cancers are relatively rare tumors that appear more frequently in women than in men. Accordingly, most studies focus on studying risk factors for thyroid cancer in women and consequently on various hormonal or reproductive factors that are specific for women. The aim of our study was to examine risk factors for developing well-differentiated thyroid cancer in men. Heretofore, we did not encounter in the literature a study that was solely focused on studying risk factors for well-differentiated thyroid cancer in men. METHODS: A case-control study was performed from 2005 to 2010. The case group included 204 consecutive well-differentiated thyroid cancers in male patients (180 papillary and 24 follicular including Hürthle cell). The control group comprised the same number of cases. Patients were individually matched by gender, age and place of residence. Statistical analysis included conditional univariate and multivariate logistic regression methods. RESULTS: According to univariate logistic regression, well-differentiated thyroid cancer in men was significantly related to smoking status, duration of smoking, number of cigarettes smoked per day, history of goiter or thyroid nodules, history of non-thyroid cancer, diabetes mellitus, radiotherapy of the head and neck, and history of malignant tumors. According to multivariate logistic regression, it was independently related to smoking status (OR = 0.36; 95% CI, 0.19-0.69), history of goiter or thyroid nodules (OR = 9.19; 95% CI, 1.25-64.58), and a history of malignant tumors (OR = 2.11; 95% CI, 1.19-7.33). CONCLUSIONS: Risk factors for well-differentiated thyroid cancer in men were goiter or thyroid nodules and family history of malignant tumors. Cigarette smoking was negatively associated with the disease.
