Prevalence of metabolic syndrome and associated risk factors among Turkish adults: Trabzon MetS study

Objective In order to estimate the prevalence of metabolic syndrome (MetS) as defined by NCEP Adult Treatment Panel III (ATP III) criteria in the Trabzon Region and its associations with demographic factors (age, sex, marital status, reproductive history in women, and level of education), socioeconomic factors (household income and occupation), family history of selected medical conditions (diabetes, hypertension, and obesity), lifestyle factors (smoking habits, physical activity, and alcohol consumption) in the adult population. Research Methods and Procedures In this cross-sectional survey, a sample of households was systematically selected from the central province of Trabzon and its nine towns. A total of 4,809 adult subjects ≥20 years (2,601 women and 2,208 men) were included in the study. Blood pressure levels were measured for all subjects. The persons included in the questionnaire were invited to the local medical centers for blood examination between 08:00 and 10:00 following 12 h of fasting. Fasting serum glucose (FBG) levels and lipid profile were measured with autoanalyzer. MetS was defined according to guidelines from the NCEP ATP III diagnostic criteria. Results The prevalence of MetS was 26.9%: 31.3 in women and 21.7% in men. The prevalence increased with age, being highest in the 60–69-year-old age group (53.4%) but lower again in the ≥70 age group. MetS was associated positively with marital status, parity, cessation of cigarette smoking, and negatively with the level of education, alcohol consumption, current cigarette use, household income, and physical activity. Hypertension was found as the most common MetS component in our study (57.4%). Others in decreasing order were abdominal obesity (40.9%), low high-density lipoprotein-C (HDL-C) (31.8%), hypertriglyceridemia (30.7%), and high FBG levels (9.2%). Similarly, in the subjects diagnosed with MetS, HT had the highest prevalence (91.9%). This was followed by abdominal obesity (82.3%), hypertriglyceridemia (74%), low HDL-C (68.6%), and high fasting blood glucose levels (28.6%). Discussion MetS is moderately common and an important health problem in the adult population of Trabzon. In order to control MetS and its components, effective public health education and taking urgent steps are needed. These steps include serious education, providing a well-balanced diet and increasing physical activity.     

Comparison and evaluation of experimental mediastinitis models: precolonized foreign body implants and bacterial suspension inoculation seems promising

Background  

Post-sternotomy mediastinitis (PSM) is a devastating surgical complication affecting 1–3% of patients that undergo cardiac surgery. Staphylococcus aureus is one of the most commonly encountered bacterial pathogen cultured from mediastinal samples obtained from patients with PSM. A component of the membrane of the gram positive bacteria, lipoteichoic acid, stimulates the blood monocytes and macrophages to secrete cytokines, radicals and nitrogen species leading to oxido-inflammatory damage. This seems to be responsible for the high mortality rate in PSM. For the evaluation of the pathogenesis of infection or for the investigation of alternative treatment models in infection, no standard model of mediastinitis seems to be available. In this study, we evaluated four mediastinitis models in rats.     

Effectiveness of a multidimensional approach for prevention of ventilator-associated pneumonia in 11 adult intensive care units from 10 cities of Turkey: findings of the International Nosocomial Infection Control Consortium (INICC)

Purpose

To evaluate the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional approach on the reduction of ventilator-associated pneumonia (VAP) in adult patients hospitalized in 11 intensive care units (ICUs), from 10 hospitals, members of the INICC, in 10 cities of Turkey.

Methods

A prospective active before-after surveillance study was conducted to determine the effect of the INICC multidimensional approach in the VAP rate. The study was divided into two phases. In phase 1, active prospective surveillance of VAP was conducted using the definitions of the Centers for Disease Control and Prevention National Health Safety Network, and the INICC methods. In phase 2, we implemented the multidimensional approach for VAP. The INICC multidimensional approach included the following measures: (1) bundle of infection control interventions, (2) education, (3) outcome surveillance, (4) process surveillance, (5) feedback of VAP rates, and (6) performance feedback of infection control practices. We compared the rates of VAP obtained in each phase. A time series analysis was performed to assess the impact of our approach.

Results

In phase 1, we recorded 2,376 mechanical ventilator (MV)-days, and in phase 2, after implementing the multidimensional approach, we recorded 28,181 MV-days. The rate of VAP was 31.14 per 1,000 MV-days during phase 1, and 16.82 per 1,000 MV-days during phase 2, amounting to a 46 % VAP rate reduction (RR, 0.54; 95 % CI, 0.42–0.7; P value, 0.0001.)

Conclusions

The INICC multidimensional approach was associated with a significant reduction in the VAP rate in these adult ICUs of Turkey.     

Comparison of intrarenal pelvic pressure during micro-percutaneous nephrolithotomy and conventional percutaneous nephrolithotomy

The micro-percutaneous nephrolithotomy (microperc) is a recently introduced percutaneous nephrolithotomy (PNL) technique that is performed through a 4.8Fr all-seeing needle. We aimed to measure the intrarenal pelvic pressure (IPP) during microperc and compare it with the levels of conventional PNL. A total of 20 patients with 1- to 3-cm renal calculi resistant to shock wave lithotripsy were treated either with microperc (Group-1, n: 10) or conventional PNL (Group-2, n: 10) by the same surgical team. The IPP was measured during different stages (entrance into the collecting system, stone fragmentation, and before termination) of the procedures by an urodynamic machine using the 6Fr ureteral catheter. All the variables were statistically compared between the two groups. The demographic values of the patients were similar. The operation time and duration of hospitalization were significantly prolonged in conventional PNL group (p = 0.034, p = 0.01, respectively). The mean drop in hematocrit levels was significantly lower in microperc group (3.5 ± 1.5 vs. 1.8 ± 0.8; p = 0.004). The IPP was significantly higher in microperc group during all steps of the procedure. The highest level of the IPP was measured as 30.3 ± 3.9 and 20.1 ± 3.1 mmHg in Group 1 and Group 2, respectively (p < 0.0001). However, the complication and success rates were found comparable. In conclusion, we demonstrate that the level of IPP is significantly increased during microperc compared to conventional PNL. Microperc should be used cautiously in cases with impaired drainage of the collecting system.     

Recurrence after incisional hernia repair: Results and risk factors

A relatively low success rate in recurrent incisional hernia repair has prompted us to review the effects of certain risk factors on the long-term outcome of our cases. In this study, 109 recurrent incisional hernias were repaired and reviewed between 7 and 92 months after the operation. The recurrence rate was 45.0%. Many conditions that have been implicated as causal factors in the occurrence of incisional hernias were not found to be associated with recurrence after repair. However, chronic constipation was determined to be the most prominent risk factor associated with late recurrence.
