RESUMEN

BACKGROUND: Bisphosphonates are the mainstay therapeutic options for prevention of skeletal-related events and generally used for up to 2 years in bone metastatic cancer patients. AIM: We aimed to evaluate the long-term outcomes of prolonged (> 2 years) bisphosphonate usage in bone metastatic breast cancer (BMBC) patients. METHODS: Ninety-nine BMBC patients who had prolonged bisphosphonates were evaluated retrospectively for long-term outcomes and survival rates. RESULTS: Median duration of bisphosphonate therapy was 46.8 (24-198) months. Seven patients had bisphosphonate-related adverse events (osteonecrosis of the jaw (ONJ) (n = 6), ONJ and renal failure (n = 1)). Bisphosphonate was switched to another one because of bone metastasis progression in more than one-third of the patients (n = 36, 36.3%). The patients who had bisphosphonate switch therapy had statistically significant longer overall survival (p < 0.01). Neither duration nor type of bisphosphonates had effect on frequency of bisphosphonate-related adverse events. CONCLUSION: Bisphosphonates might be prolonged for more than 2 years in BMBC patients with an acceptable toxicity profile. In addition, bisphosphonates switch therapy should be preferred in those with progressive bone metastasis since it might contribute to better survival despite bisphosphonates could not have been shown to have survival benefit in previous studies.

RESUMEN

AIM: This study aims to evaluate the prognostic and predictive value of plasma plasminogen activator inhibitor-1 (PAI-1) and endoglin in metastatic colorectal cancer (mCRC) patients receiving chemotherapy with bevacizumab. MATERIALS AND METHODS: Between April 2012 and September 2013, 47 mCRC patients with a mean age of 58.5 ± 9.6 years were included in the study. Male-to-female ratio was 29/18. The baseline and posttreatment plasma PAI-1 and serum endoglin levels after 3 cycles of bevacizumab-containing chemotherapy were evaluated. The percent change between baseline and posttreatment levels after treatment was also recorded. RESULTS: The median follow-up duration was 26.6 months (range 1.8-70.2 months). The clinical benefit rate was 70% (partial response [32%], stable disease [38%]). Overall survival was 20.8 ± 1.5 months. The patients with progressive disease had statistically significantly higher baseline PAI-1 level (57.9 pg/mL vs. 29.9 pg/mL, P = 0.036). The percent change of the plasma PAI-1 level after the third cycle of treatment was also statistically significantly lower in those with clinical benefit (P = 0.035). However, there was no statistically significant difference in endoglin level and its change after therapy with respect to the response to treatment (P = 0.771 and P = 0.776, respectively). Plasma PAI-1 level had no statistically significant effect on survival (P = 0.709). CONCLUSION: Baseline plasma PAI-1 level and its percent change with bevacizumab were shown to have statistically significant predictive value for the response to therapy whereas serum endoglin had no statistically significant predictive value for the response to therapy. However, neither PAI-1 nor endoglin had prognostic significance in mCRC.

RESUMEN

BACKGROUND: Traumatic nasal deformities have a wide spectrum of presentations, which further complicates their management and preoperative planning. Although many methods and algorithms have been proposed for management of specific posttraumatic nasal deformities, such as twisted, deviated, saddle, or short nose, these algorithms usually focus on a specific deformity in isolation from the remainder of the nose. OBJECTIVES: The aim of this study is to present an algorithm for traumatic nasal deformities and to evaluate the functional and aesthetic outcomes of this new algorithm by a preoperative and postoperative quality-of-life questionnaire. METHODS: Patients with traumatic nasal deformity were operated on according to our surgical algorithm. Preoperative and postoperative Rhinoplasty Outcome Evaluation (ROE) scores, which is a rhinoplasty outcome survey, were evaluated. RESULTS: A total of 120 patients were included in the study. The mean preoperative ROE score was 3.3 ± 1.9 and mean postoperative ROE score was 20.4 ± 3.2. There was a statistically significant difference between preoperative and postoperative ROE scores (P < 0.001). There was a negative, mild to moderate, statistically significant correlation between preoperative scores and benefit (difference between postoperative and preoperative scores) (r = -0.465, P < 0.001), which means patients with lower scores had more improvement from the surgery. During the follow-up period, relapse of deviation, hypertrophic inferior turbinate, and intranasal synechia were found in 9% (n = 11), 6.6% (n = 8), and 3.3% (n = 4) of patients, respectively. CONCLUSIONS: In this study, a comprehensive surgical algorithm applicable to all traumatic nasal deformities is suggested, and the results of 120 patients with traumatic nasal deformities are presented.

RESUMEN

APOBEC3B belongs to a protein family of cytidine deaminases that can insert mutations in DNA and RNA as a result of their ability to deaminate cytidine to uridine. It has been shown that APOBEC3B-catalysed deamination provides a chronic source of DNA damage in breast cancers. We investigated APOBEC3B expression in four drug resistant breast cancer cell lines (Doxorubicin, Etoposide, Paclitaxel and Docetaxel resistant MCF-7 cell lines) using a novel RNA in situ hybridization technology (RNAscope) and compared expression levels with drug sensitive MCF-7 cell line. After RNAscope staining, slides were scanned and saved as digital images using Aperio scanner and software. Quantitative scoring utilizing the number of punctate dots present within each cell boundary was performed for the parameters including positive cell percentage and signal intensity per positive cell. In Doxorubicin and Etoposide resistant MCF-7 cell lines, APOBEC3B expression was approximately five-fold increased (23% and 24% respectively) with higher signal intensity (1.92 and 1.44 signal/cell, respectively) compared to drug sensitive MCF-7 cell line (5%, 1.00 signal/cell) with statistical significance. The increase of APOBEC3B expression in Docataxel resitant and Paclitaxel resistant MCF-7 cell lines was not very high. In conclusion, APOBEC3B expression was increased in some population of tumor cells of drug resistant cell lines. At least for some drugs, APOBEC3B expression may be related to drug resistance, subjecting to some tumor cells to frequent mutation.

RESUMEN

OBJECTIVES: The aim of this cross-sectional epidemiologic study was to investigate the prevalence and distribution of musculoskeletal disorders causing unfitness to Turkish Military Service. METHODS: This study has been carried out by examining the medical reports of 1.777.500 people who applied to the Turkish Armed Forces for military service between 2009-2011. Age and geographic region of individuals were compiled and organized in groups. Musculoskeletal disorders were classified mainly as fracture sequel, spine disorders, absence of phalanges, extremity amputation, aggressive or multiple benign tumors of bones and pes planus. RESULTS: Unfitness to military service caused by musculoskeletal disorders was found to be 6.53‰ in 2009, 7.10‰ in 2010 and 7.28‰ in 2011. The prevalence of musculoskeletal diseases has increased by years. The prevalence of fracture squeal by years was found to be 2.83‰ in 2009, 3.10‰ in 2010 and 3.03‰ in 2011. In this study, the most common musculoskeletal disorders were: limitation of joint mobility (0.89‰), degeneration of joint surface (0.69‰), lower and upper limb discrepancies (0.60‰), posterior fusion surgery (0.59‰) and the absence of the phalanges in hand (0.51‰). We found an increase in both the prevalence of posterior fusion surgery and the absence of the phalanges in study group. CONCLUSION: These results has given information about severe musculoskeletal disorders among young adult male in Turkey. New studies including young adult female will add important information to our knowledge about musculuskelatal problems in our community.

RESUMEN

OBJECTIVES: In 1981, Peter A. Stewart published a paper describing his concept for employing Strong Ion Difference. In this study we compared the HCO3 levels and Anion Gap (AG) calculated using the classic method and the Stewart method. METHODS: Four hundred nine (409) arterial blood gases of 90 patients were collected retrospectively. Some were obtained from the same patients in different times and conditions. All blood samples were evaluated using the same device (ABL 800 Blood Gas Analyzer). HCO3 level and AG were calculated using the Stewart method via the website AcidBase.org. HCO3 levels, AG and strong ion difference (SID) were calculated using the Stewart method, incorporating the parameters of age, serum lactate, glucose, sodium, and pH, etc. RESULTS: According to classic method, the levels of HCO3 and AG were 22.4±7.2 mEq/L and 20.1±4.1 mEq/L respectively. According to Stewart method, the levels of HCO3 and AG were 22.6±7.4 and 19.9±4.5 mEq/L respectively. CONCLUSIONS: There was strong correlation between the classic method and the Stewart method for calculating HCO3 and AG. The Stewart method may be more effective in the evaluation of complex metabolic acidosis.

RESUMEN

Vascular inflammation plays an important role in the pathophysiology of hypertension and high levels of endocan may reflect ongoing vascular inflammation in hypertensive patients. In the present hypothesis-generating study, we aimed at investigating the comparative effects of amlodipine and valsartan on endocan levels in newly diagnosed hypertensive patients. The study population consisted of 37 untreated hypertensive patients who were randomized to the two treatment arms. After baseline assessment, each patient was randomly allocated to either 10 mg daily of amlodipine (n = 18, 7 males) or 160 mg daily of valsartan (n = 19, 3 males) and treated for a 3-month period. Sphygmomanometric blood pressure (BP) and serum endocan were measured before and every 2 weeks during drug treatment. There was no statistically significant difference between the two treatment arms as far as baseline socio-demographic and clinical characteristics are concerned. After a 3-month treatment period, systolic and diastolic BP values significantly reduced by antihypertensive treatment (p < 0.001). Furthermore, endocan levels were significantly decreased in both treatment arms (p < 0.05). However, amlodipine caused a greater percent decrease in circulating endocan levels compared with valsartan at the end of the treatment period. Both drugs reduced high sensitivity C-reactive protein values. However, the statistical significant difference vs baseline was achieved only in the group treated with amlodipine. No correlation was found between endocan plasma levels and BP reduction. The results of this hypothesis-generating study suggest that amlodipine and valsartan decrease endocan levels in newly diagnosed hypertensive patients. The effects, which are more evident with amlodipine, may contribute to the anti-inflammatory effects exerted by the two drugs on the vascular target.

RESUMEN

OBJECTIVE: We aimed to evaluate the relationship between estimated glomerular filtration rate (eGFR) and QT dispersion (QTd) in patients with coronary artery disease (CAD). METHODS: Sixty patients(mean age 62.72 ± 12.48 years) included 46 male, (mean age 60.89 ± 12.70 years)and 14 female (mean age 68.71± 9.86 years) were enrolled in this study. Patients were divided into 2 groups according to their eGFR using the 6 variable MDRD equation. Group 1 consisted of patients with estimated eGFR<60 ml/min/1.73m(2) and Group 2 consisted of patients witheGFR ≥ 60 ml/min/1.73m(2). RESULTS: Baseline patient characteristics were homogeneous in both groups except for age, gender and smoking.Also, the extent of CAD was similar in both groups (p > 0.05) QTd values were found higher in group 1 than those of group 2 (57.23 ± 40.65 ms vs. 31.23 ± 14.47 ms, p = 0.002). After adjustment for age, gender and smoking using one-way ANCOVA test, statistically significant difference in QTd still existedbetween the groups (p=0.038). CONCLUSION: QTd tends to be higher in patients with poor renal function independent of severity of angiographical CAD. QTd may be a potentially useful non-invasive test in the management of patients with poor renal function, especially those with CAD.

RESUMEN

PURPOSE: To determine the effect of a capsular tension ring (CTR) implantation in preventing posterior capsular opacification (PCO) after cataract surgery in patients with high myopia. MATERIALS AND METHODS: In this prospective single-surgeon standardized-surgical-procedure fellow-eye comparison trial, 34 patients with high myopia had phacoemulsification surgery. Although one eye received an acrylic intraocular lens (IOL) and CTR, other eye received only an IOL as control. PCO, within the capsulorhexis overlap, was documented by standardized digital retroillumination images at least 2 years post-operatively, and the percentage area of PCO was scored (scale 0%-100%) using the POCOman software system. The PCO score and the incidence of neodymium-doped yttrium aluminum garnet (Nd: YAG) capsulotomy of groups, and correlations between PCO score and presence of CTR, age, phaco time, refraction, and axial length (AL) were determined. RESULTS: The mean time interval from surgery to PCO measurement was 43.4 ± 11.2 months for the eyes with a CTR and 43.1 ± 11.6 months for the controls (P = 0.91). The PCO score of the eyes with a CTR was significantly lower than in the controls (5.9 ± 4.3 vs. 22.3 ± 12.2, respectively; P < 0.001). There were statistically insignificant correlations between PCO score and pre-operative refraction (r = 0.02; P = 0.90), AL (r = 0.03; P = 0.80), phaco time (r = 0.11; P = 0.53), and patient's age (r = 0.23; P = 0.55). No patient with a CTR had a Nd: YAG laser capsulotomy, but it was six in controls (P = 0.025). CONCLUSIONS: CTR implantation seems to be effective in reducing the PCO and Nd: YAG laser capsulotomy rates in high myopic eyes.

RESUMEN

BACKGROUND: Mutations in the KRAS gene occur at an early stage in the development of colorectal carcinoma. Importantly, KRAS mutation predicts resistance to anti-epidermal growth factor receptor therapy in stage IV disease. GOALS: The aim of the current study is to correlate histologic features of colon cancer with the presence of KRAS mutations. STUDY: Tumor tissue from 145 colon cancer resections was tested for KRAS mutations. KRAS mutation status was correlated with demographic and histologic characteristics. Statistical analysis was performed using the Pearson χ2 test and multivariate analysis. RESULTS: KRAS mutations were present in 55/145 cases (37.9%), consistent with reported rates. KRAS mutations were significantly associated with usual adenocarcinoma morphology (multivariate P=0.014), peritumoral lymphocytic response (χ2, P=0.028; multivariate P=0.017), T3-T4 status (χ2, P=0.012; multivariate P=0.015), right-sided location (multivariate P=0.027), absence of lymphovascular invasion (multivariate P=0.008), and metastases at the time of resection (multivariate P=0.034). No association was found between KRAS mutation status and other factors. CONCLUSIONS: Specific morphologic features in colon cancer suggest a higher likelihood of the presence of KRAS mutations. These morphologic features overlap partially with those associated with DNA mismatch repair gene mutations. If confirmed, these results may suggest a paradigm for directed KRAS testing.

RESUMEN

BACKGROUND: Transthoracic cardioversion (TTC) is widely used in emergency departments and daily clinical practice. TTC may cause skin lesions on the application of apical and sternal paddle areas. The lesions are characterised by redness, erythema and blister(s), and can be defined as first degree burns locally causing pain and increased sensitivity. AIM: To evaluate the effectiveness of local cold application on reducing the incidence, severity and pain/sensitivity of skin burns in patients who underwent TTC. METHODS: The study was conducted in the intensive care unit of the cardiovascular surgery department. The patients were assigned to study (n=24) and control groups (n=24). Local cold application was performed for a 1 hour period on patients in the study group, whereas only clinical procedures were applied in the control group following TTC. Incidence and severity of burn was evaluated 2 h after TTC, and pain/sensitivity scores were evaluated at 2, 4 and 24 h after TTC. Results The incidence of burn was significantly lower in the study group (3/24) compared to the control group (21/24) (12.5% vs 83.3%, p<0.001). Pain/sensitivity scores were significantly lower in the study group compared to the control group (p<0.05). CONCLUSION: Local cold application following TTC is an effective means of reducing the incidence and severity of burns and pain/sensitivity. It is cost-effective and can easily be applied by nurses in medical/surgical units and emergency departments.

RESUMEN

The knowledge about vitamin B(12) and folic acid levels in preserving bone mass in older men is limited. In this retrospective study, we aimed to find out whether levels of vitamin B(12) and folic acid are related to BMD in older men. Two hundred and sixty-nine older men were included in the study. Forty-two (15.6%) of them had osteoporotic, 150 (55.8%) had osteopenic, and 77 (28.6%) had normal BMD. Vitamin B(12) and folic acid levels were categorized as indicating normal, borderline, or low vitamin statuses. Femur neck densities showed statistically significant differences in subjects having low, borderline, and normal vitamin B(12), respectively. There were no significant differences between the three tertiles of vitamin B(12) in femur total, trochanteric, and intertrochanteric densities. After adjustment for age, body mass index (BMI), alcohol, smoking, and exercise with analysis of covariance, the difference was still statistically significant between two groups for femur neck density (p=0.011). No significant difference was observed between the groups of folic acid in any femur sites. We found that the normal level of vitamin B(12) in older men may be related to a decrease of femur neck bone loss.

RESUMEN

PURPOSE: The present study was conducted to develop a clinical pathway for breast cancer patients undergoing breast surgery. We also aimed to determine the effects of this model on the (1) reduction of patient anxiety, (2) satisfaction of the patient, and (3) quality of life. METHODS: The present study was conducted using a quasi-experimental nonequivalent study design. The study was applied to 69 patients diagnosed with breast cancer, who underwent surgical operations. We collected data using a questionnaire form, the State-Trait Anxiety Inventory, Questionnaire for the Evaluation of Patient Satisfaction, and SF-36 Quality of Life Scale. The data were analysed using percentages, the Student's t-tests, Mann-Whitney U-Test, and chi-square tests. RESULTS: This study showed that a comprehensive breast surgery clinical pathway significantly improved the quality of life and patient treatment satisfaction and reduced anxiety, even though it did not affect the hospitalization time. According to the level of state anxiety, there was not a meaningful statistical difference between groups but the anxiety level of the study group was lower than the control group and there was not a statistically meaningful difference between them in the period of pre-discharge. For quality of life, the physical, general health, vitality, social functioning, and emotional subscale averages were higher for the study group. CONCLUSION: The results of the study indicate that the implementation of a clinical pathway on patients with breast surgery has a positive effect on increasing patient satisfaction, decreasing patient anxiety levels, and improving their quality of life.

RESUMEN

BACKGROUND/AIMS: Despite all the knowledge about gastric cancer, there is no prognostic biomarker which could be useful for early detection. Dickkopf-1 (DKK-1), a secreted protein, is known as a negative regulator of the Wnt signaling pathway. DKK-1 is reported to be over expressed in many malignant tissues. The purpose of this study was to elucidate the normal level of serum DKK-1 (sDKK-1) levels in healthy Turkish peoples and to investigate the clinical utility of sDKK-1 levels for gastric cancer screening. METHODOLOGY: Serum DKK-1 levels were measured in 69 healthy controls and in 60 gastric adenocarcinoma patients with ELISA and sDKK-1 levels were compared with clinicopathological features and outcomes in gastric cancer patients. RESULTS: Serum concentrations of DKK-1 in gastric adeno cancer patients were significantly higher than control patients (p<0.001). The optimal cut-off for sDKK-1 levels order to discriminate control group from gastric cancer patients was 25U/mL with sensitivity equal to 100% and specificity equal to 100%. CONCLUSIONS: Serum DKK-1 levels may be a potentially useful novel serologic marker for gastric cancers.

RESUMEN

BACKGROUND: Surgical treatment of bronchiectasis is associated with acceptable mortality and morbidity rates. To date, few reports on the prediction of postoperative morbidity using some preoperative measures have been presented. We present our results regarding the influence of some specific factors on postoperative morbidity on young adult patients who were treated surgically for bronchiectasis. METHODS: Between January 2000 and July 2007, 122 patients were operated upon. Female gender, increased number of resected segments, presence of haemoptysis and bilateral disease, compromised pulmonary function test (FEV1/VC<60%) and absence of preoperative fiberoptic bronchoscopy (FOB) were examined as the potential risk factors for postoperative complications such as persistent air leak (PAL), atelectasis, residual air space (RAS), bronchopleural fistula (BPF) and empyaema. RESULTS: There was no operative mortality. Morbidity was observed in a total of 16 patients with an overall morbidity rate of 13.1%. Complete resection was achieved in 88 patients (72.1%). The number of resected segments was not found to be significantly associated with increased morbidity. Presence of preoperative haemoptysis did not correlate with postoperative complications significantly. Absence of preoperative FOB was not found to be associated with post-operative complications (p<0.05). Compromised PFT was significantly associated with RAS (p=0.028), however it was not associated with increased risk of PAL, atelectasis or empyaema significantly. CONCLUSION: Multi-segmental resectable bronchiectasis should not be considered an occult risk factor for morbidity after resection. Associated non-severe haemoptysis and absence of preoperative bronchoscopy are not associated with significant increased risk of postoperative morbidity.

RESUMEN

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) conveys high mortality rates. Soluble TNF-like weak inducer of apoptosis (sTWEAK) and long pentraxin 3 (PTX3) are predictors of mortality in dialysis patients and determinants of endothelial dysfunction. Now, we hypothesize that both sTWEAK and PTX3 act as biomarkers of cardiovascular outcomes in nondialysis CKD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Cross-sectional analysis in which flow-mediated dilation (FMD) and intima-media thickness (IMT) were assessed in 257 nondialysis stage 1 to 5 CKD patients (mean age, 52 ± 12 years; 130 men), together with biochemical measurements and sTWEAK and PTX3 assessments. Patients were followed for cardiovascular outcomes. RESULTS: PTX3 and IMT increased, whereas FMD and sTWEAK decreased across CKD stages (P<0.001 for all). Both PTX3 and sTWEAK appeared as strong determinants of FMD in multivariate analysis. The univariate associations of sTWEAK and PTX3 with IMT were dependent on estimated GFR. After a median of 39 months (range, 2 to 43 months), 22 fatal and 57 nonfatal cardiovascular events occurred. In a Cox model excluding PTX3, decreasing sTWEAK concentration was associated with increased risk of cardiovascular events independently of basic confounders (age, gender, estimated GFR, C reactive protein, diabetes, and cardiovascular comorbidity) and FMD. In a model excluding sTWEAK, circulating levels of PTX3 were directly associated with cardiovascular outcomes independently of basic confounders, but this association was lost after adjustment for FMD. CONCLUSIONS: Both PTX3 and sTWEAK levels associated with the endothelial dysfunction observed with progressive kidney failure. Additionally, both biomarkers impacted the predictability of cardiovascular outcomes.

RESUMEN

OBJECTIVE: Novel treatment strategies are needed in the treatment of endometriosis due to limited success rates with the currently available options. As inflammatory and immunological mechanisms have been shown to be involved in the mechanism of the disease, new modalities are likely to emerge. We investigated the effects of infliximab (INF), etanercept (ETA) and letrozole on the regression of experimental endometriosis. STUDY DESIGN: In this experimental randomized trial, endometriosis was induced surgically in 44 adult female Sprague-Dawley rats. Establishment of implants was confirmed in 41 animals by a second operation on the 21st day. The rats were then randomly divided into four groups. Group I (n = 10) served as controls. Group II (n = 11) received letrozole (0.18 mg/kg, i.p.), group III (n = 10, i.p.) ETA (2.016 mg/kg, i.p.), and group IV (n = 10) INF (15.12 mg/kg, i.p.) for a second 21-day period. Endometriotic implant size along with peritoneal fluid VEGF level and immunoreactivity were determined before and after the treatment in each group. RESULTS: Endometriotic implant size reduced in all treatment groups. The effect of letrozole and ETA on implant size was similar but was significantly better than INF. Level of VEGF in peritoneal fluid did not change in any treatment group but post-treatment VEGF immunoreactivity was found significantly lower in the letrozole treated group. CONCLUSIONS: Letrozole and ETA caused a regression on the implant size in experimental endometriosis. The only group with decreased VEGF expression was letrozole.

RESUMEN

BACKGROUND: Epidemiologic researches about oral mucosal lesions have been performed in different populations. But, in dermatology outpatients, oral mucosal lesions have not been investigated previously. OBJECTIVE: We aimed to determine the prevalence of oral mucosal lesions among dermatology outpatients and the relationship between OML and smoking, alcohol intake, denture and dental filling use and skin diseases. METHODS: Randomly selected 1041 dermatology outpatients were examined for dermatological diseases and oral mucosal lesions. All of the patients were questioned about smoking, alcohol intake, denture and dental filling use. RESULTS: In 235 patients, oral mucosal lesions were recorded. 268 (25.7%) of the patients had history of smoking, 42 (4%) drinking alcohol and 180 (17.3%) denture and dental filling. 32 (64%) of the smokers, 54 (30%) of denture users and 10 (23.8%) alcohol consumers had at least one OML. Age and smoking were found as significant risk factors for oral mucosal lesions. Fissured tongue was the most common oral lesion and it was seen significantly higher in patients with denture. Smoking was risk factor for coated tongue and linea alba. CONCLUSIONS: Oral mucosa should be examined carefully even if the patients do not attend with the complaint of oral lesions, especially in elderly patients, smokers and denture users.

RESUMEN

BACKGROUND: Rapid hematological engraftment at autologous peripheral stem cell transplantation (APSCT) is a significant factor in reduction of early transplant-related complications and costs. For this reason, it is important to determine influences on hematological recovery. METHODS: This study was designed to evaluate factors affecting leukocyte and platelet engraftment times after high dose chemotherapy following APSCT. A total of 228 patients (131 males and 97 females) were enrolled. RESULTS: There were statistically significant differences between patients with CD34+ cell doses ≥ 2.5 x 106/kg (n=180) and < 2.5 x 106/kg (n=48), regarding leukocyte engraftment at 11 and 12 days, respectively (p<0.02), between G-CSF (n=167) and GM-CSF (n=61) posttransplant regarding median leukocyte engraftment times (p=0.005), and between with (n=75) or without (n=153) history of pretransplant radiotherapy for both leukocyte and platelet engraftment times (p<0.001). CONCLUSIONS: For leukocyte engraftment, a history of pretransplant radiotherapy, type of growth factor used and number of CD34+ cells infused, and for platelet engraftment, a history of pretransplant radiotherapy were found to be independent variables on multivariate analysis with the Cox regression method.

RESUMEN

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is linked to an increased risk of cardiovascular disease. Mean platelet volume (MPV), a determinant of platelet activation, is an emerging risk factor for atherothrombosis. AIMS: The aim of this study was to investigate the levels of MPV in subjects with NAFLD having no confounding factors for atherosclerosis such as obesity, diabetes mellitus, and hypertension. In addition, the possible relationship between MPV and carotid artery intima media thickness (CIMT), a well known marker of subclinical atherosclerosis, was also studied. METHODS: MPV and CIMT levels were measured in 60 biopsy-proven NAFLD subjects and 54 healthy controls. Age and sex were similar between two groups. RESULTS: Body mass index and waist circumference levels were higher in the NAFLD group when compared to the controls. There were no differences between the two groups regarding LDL cholesterol levels, whereas HDL cholesterol levels were lower in the NAFLD group. MPV and CIMT levels were not different between the two groups. According to the correlation analyses, CIMT levels were positively correlated to age in patients with NAFLD. However, no significant correlation was found between MPV and CIMT levels. CONCLUSIONS: The results of this study do not show any difference in MPV levels between subjects with NAFLD and controls. These finding suggests that in the absence of other metabolic risk factors, MPV might not be involved in the mechanism(s) of increased cardiovascular risk in NAFLD.
