Investigation the effects of 2-aminoethoxydiphenyl borate (2-APB) on aminoglycoside nephrotoxicity.

Investigation the protective effect of transient receptor potential channel modulator 2-Aminoethoxydiphenyl Borate (2-APB) on aminoglycoside nephrotoxicity caused by reactive oxygen species, calcium-induced apoptosis and inflammation was aimed. Forty Wistar rats were divided (n=8) as follows: Control group; DMSO group; 2-APB group; Gentamicin group (injected 100 mg/kg gentamicin intramuscularly for 10 days); Gentamicin+ 2-APB group (injected 2 mg/kg 2-APB intraperitoneally, then after 30 minutes 100 mg/kg gentamicin was injected intramuscularly for 10 days). Blood samples were collected for biochemical analyses, kidney tissue samples were collected for light, electron microscopic and immunohistochemical investigations. In gentamicin group glomerular degeneration, tubular dilatation, vacuolization, desquamation of tubular cells and hyaline cast formation in luminal space and leukocyte infiltration were seen. Disorganization of microvilli of tubular cells, apical cytoplasmic blebbing, lipid accumulation, myelin figure like structure formation, increased lysosomes, mitochondrial swelling and disorganization of cristae structures, apoptotic changes and widening of intercellular space were found. TNF-α, IL-6 and caspase 3 expressions were increased. BUN and creatinine concentrations were increased. Increase in MDA levels and decrease in SOD activities were determined. Even though degeneration still continues in gentamicin+2-APB treatment group, severity and the area it occupied were decreased and the glomerular and tubule structures were generally preserved. TNF-α, IL-6, caspase 3 immunoreactivities and BUN, creatinine, MDA concentrations were reduced and SOD activities were increased markedly compared to gentamicin group. In conclusion, it has been considered that 2-APB can prevent gentamicin mediated nephrotoxicity with its anti-oxidant, anti-apoptotic and anti-inflammatory effects.

The effect of mindfulness meditation on dental anxiety during implant surgery: a randomized controlled clinical trial.

Dental implant surgery is almost always associated with patient anxiety. Anxiety during dental surgical procedures triggers an increase in sympathetic activity. Mindfulness meditation (MM) is often associated with high levels of relaxation in the form of increased parasympathetic tone and decreased sympathetic activity. However, the effect of MM on dental anxiety is not clear. The current study aimed to show the effects of a MM as a sedative technique during dental implant surgery by examining the State-Trait Anxiety Inventory (STAI-S), bispectral index (BIS), cortisol levels (CL), systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR) and saturation (SpO2) parameters. HR, SBP, DBP, SpO2, BIS score and CLs were compared at the baseline, immediately before-, during-, and immediately after surgery between the test and control groups. We found that the MM resulted in significant decrease in BIS together with positive effects on hemodynamic parameters (decrease of HR, SBP, DBP and increase of SpO2), psychological findings (improvement on STAI-S scores) and biochemical outcomes (decreased CL). In conclusion, the results demonstrate that MM appeared to be a reliable strategy for managing stress during dental implant operation with benefits in psychological, physiological and biochemical outcomes.

Perspectives of adult patients with lysosomal storage diseases on the transition from pediatric to adult healthcare in Turkey.

AIM: In many countries, adult clinics specifically dedicated to adult patients with lysosomal storage diseases (LSDs) do not exist. In Turkey, these patients are managed either by pediatric metabolic specialists or adult physicians who do not specifically specialize in LSDs. In this study, we aimed to identify the unmet clinical needs of these adult patients and their suggestions. METHODS: The focus group participants were 24 adult LSD patients. Interviews were conducted in person. RESULTS: A total of 23 LSD patients and parents of a patient with mucopolysaccharidosis type-3b with intellectual deficit were interviewed, with 84.6% of patients diagnosed after the age of 18 years and 18% of patients diagnosed before the age of 18 years desiring management by adult physicians. Patients with particular physical characteristics or severe intellectual deficit declined the transition. Patients reported structural problems in the hospital and social problems associated with pediatric clinics. They made suggestions to facilitate the possible transition. CONCLUSION: With improved care, more patients with LSDs survive into adulthood or receive the diagnosis in adulthood. Children with chronic diseases need to transition to the care of adult physicians when they reach adulthood. Thus, there is an increasing need for adult physicians to manage these patients. In this study, most LSD patients accepted a well-planned and organized transition. Problems were related to stigmatization and social isolation in the pediatric clinic or adult issues with which pediatricians are not familiar. There is a need for adult metabolic physicians. Thus, health authorities should adopt necessary regulations for training of physicians in this field.

Worse pre-admission quality of life is a strong predictor of mortality in critically ill patients.

Objectives: In this study, we aimed to investigate whether quality of life (QoL) before intensive care unit (ICU) admission could predict ICU mortality in critically ill patients. Patients and methods: Between January 2019 and April 2019, a total of 105 ICU patients (54 males, 51 females; mean age: 58 years; range, 18 to 91 years) from two ICUs of a tertiary care hospital were included in this cross-sectional, prospective study. Pre-admission QoL was measured by the Short Form (SF)-12- Physical Component Scores (PCS) and Mental Component Scores (MCS) and EuroQoL five-dimension, five-level scale (EQ-5D-5L) within 24 h of ICU admission and mortality rates were estimated. Results: The overall mortality rate was 28.5%. Pre-admission QoL was worse in the non-survivors independent from age, sex, socioeconomic and education status, and comorbidities. During the hospitalization, the rate of sepsis and ventilator/hospital-acquired pneumonia were similar among the two groups (p>0.05). Logistic regression analysis adjusted for sex, age, education status, and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores showed that pre-admission functional status as assessed by the SF-12 MCS (odds ratio [OR]: 14,2; 95% confidence interval [CI]: 2.5-79.0), SF-12 PCS (OR: 10.6; 95% CI: 1.8-62.7), and EQ-5D-5L (OR: 8.0; 95% CI: 1.5-44.5) were found to be independently associated with mortality. Conclusion: Worse pre-admission QoL is a strong predictor of mortality in critically ill patients. The SF-12 and EQ-5D-5L scores are both valuable tools for this assessment. Not only the physical status, but also the mental status before ICU admission should be evaluated in terms of QoL to better utilize ICU resources.

Uterine arcuate artery calcification as a potential marker of cardiovascular risk-a preliminary study.

OBJECTIVE: Atherosclerotic cardiovascular disease is the most common cause of death in postmenopausal women. As this is a progressive disease, it is important to identify markers at an early stage during the subclinical period. Arterial calcifications are an indicator of overall atherosclerotic disease and therefore may be used as a marker for the estimation of future atherosclerotic cardiovascular events. The aims of this study are to investigate the relationship between uterine myometrial calcification (UMC) and carotid artery intima-media thickness (CIMT) and to evaluate whether UMC can be a predictive marker for the estimation of future atherosclerotic cardiovascular risk in asymptomatic postmenopausal women. METHODS: In this cross-sectional study, we assessed 81 postmenopausal women without gynecological complaints for cardiovascular risk factors, UMC, and CIMT. Participants were divided into two risk groups according to their cardiovascular risk factors. The level of UMC was determined using a new scoring system, which was based on transvaginal ultrasonography. Demographic, clinical, and laboratory parameters, UMC scores, and measurements of CIMT were evaluated. RESULTS: A moderately positive correlation was detected between CIMT and UMC scores ( r = 0.62). There was a significant relationship between UMC scores and atherosclerotic cardiovascular risk; the risk of atherosclerosis was 15.4 times higher (OR: 15.4, 95% CI: 5.1-46.8; P = 0.001) in participants with a high UMC score (≥2). According to the multivariable logistic regression model adjusted by age and duration of menopause, the risk of cardiovascular atherosclerosis increased 27.8 fold for those with CIMT of 0.075 or greater (OR: 27.8, 95% CI: 5.3-147.1; P = 0.001) and 9.2 fold for those with a UMC score of 2 or greater (OR: 9.2, CI: 1.22-69.3; P = 0.032). CONCLUSIONS: The presence of UMC has been identified as an independent predictive factor for atherosclerotic risk. Accordingly, considering UMC as an atherosclerotic cardiovascular risk factor may provide an opportunity to identify cardiovascular disease in asymptomatic postmenopausal women. When UMC is detected, women should be assessed for cardiovascular risk.

Evaluation of bone health in patients with mucopolysaccharidosis.

INTRODUCTION: This study aimed to evaluate the relationship between clinical findings, height and weight standard deviation scores, 25-hydroxyvitamin D3 (25(OH)D3) level, and dual-energy X-ray absorptiometry (DXA) results in patients diagnosed with mucopolysaccharidosis (MPS), where effective current treatments such as enzyme replacement therapy (ERT) can be accessed. MATERIALS AND METHODS: 25(OH)D3 level was measured in 126 patients with MPS (17 with MPS I, 14 with MPS II, 18 with MPS III, 33 with MPS IVA, and 44 with MPS VI; 24-524 months). DXA was performed in 45 of these patients (8 with MPS I, 4 with MPS II, 4 with MPS III, 12 with MPS IVA, and 17 with MPS VI; 62-197 months; all patients were under 18 when DXA was performed) to assess bone mineral density (BMD) of the lumbar spine. RESULTS: In total, 67.5% patients had a short stature, and 50% of them were underweight for their age. Of the patients, 13.5% were immobile, 28.6% had 25(OH)D3 deficiency, and 30.2% had an insufficient level of 25(OH)D3. BMD z score of 45 patients was - 2.5 ± 1.7. In 40% patients, it was < - 2. However, after correction for height-for-age z score (HAZ), HAZ-adjusted BMD z score was - 0.1 ± 0.9. In 2.2% patients, it was < - 2. CONCLUSION: The low BMD z score prevalence reported with DXA was misleadingly higher in children with MPS and short stature. To prevent exposure to unnecessary antiresorptive treatments in these children, the effect of severe short stature and bone geometry on DXA measurements should be considered; further studies on bone health are warranted.

The effects of connective tissue graft position on clinical and aesthetical outcomes of gingival recession treatment: a controlled randomized clinical trial.

OBJECTIVES: This randomized controlled clinical trial with 1-year follow-up compared the clinical and aesthetic results of coronally advanced flap (CAF) + connective tissue graft (CTG) positioned apical to the cemento-enamel junction (CEJ) (CAF + CTG-ACEJ) with CAF + CTG positioned on the CEJ (CAF + CTG-CEJ) for treating isolated gingival recession defects. MATERIALS AND METHODS: Thirty-eight patients with recession type 1 (RT 1) with a depth ≥ 3, gingival recessions were enrolled. Nineteen patients were randomly assigned to the CAF + CTG-ACEJ group or CAF + CTG-CEJ group. Clinical and aesthetical evaluations were made at 6 and 12 months. RESULTS: While the 6 months results showed that both surgical techniques were similar for clinical outcomes, the results achieved at the 6th month were more stable in the CAF + CTG-ACEJ group at the 12th month with significantly better recession depth, mean, and complete root coverage values and aesthetical results. CONCLUSIONS: Isolated gingival recession defects can be clinically successfully treated by both CAF + CTG-ACEJ and CAF + CTG-CEJ techniques. CLINICAL RELEVANCE: Limited studies have compared the clinical and aesthetical effects of positioning CTG apical to the CEJ for the treatment of gingival recessions. This randomized clinical study showed that CAF + CTG-ACEJ technique can provide additional benefit for the treatment. The described technique is effective in obtaining better long-term CRC stability and aesthetics.

Blood pressure, inflammation, and quality of life in patients treated with different renal replacement therapies.

Our aim was to determine the relationship between the modality of renal replacement therapy and inflammation markers, BP control, and quality of life (QoL). Sixteen hemodialysis, 17 peritoneal dialysis patients, and 27 kidney transplant receivers (KTr) have been included in this study. Short Form-36 (SF-36) for the evaluation of QoL and ambulatory BP monitoring were performed on the same day. Erythrocyte sedimentation rate, CRP, IL-6, and IL-10 were measured. While the mean IL-10, IL-6, and CRP levels were the highest in the dialysis groups, there were no significantly differences any parameters for all groups. QoL was better in the KTr almost as in healthy controls but worse in the dialysis patients. It should be taken into account that hypertension may occur at night even if the daytime BP is normal in KTr.

Could the Long-Term Oncological Safety of Laparoscopic Surgery in Low-Risk Endometrial Cancer also Be Valid for the High-Intermediate- and High-Risk Patients? A Multi-Center Turkish Gynecologic Oncology Group Study Conducted with 2745 Endometrial Cancer Cases. (TRSGO-End-001).

This study was conducted to compare the long-term oncological outcomes of laparotomy and laparoscopic surgeries in endometrial cancer under the light of the 2016 ESMO-ESGO-ESTRO risk classification system, with particular focus on the high-intermediate- and high-risk categories. Using multicentric databases between January 2005 and January 2016, disease-free and overall survivals of 2745 endometrial cancer cases were compared according to the surgery route (laparotomy vs. laparoscopy). The high-intermediate- and high-risk patients were defined with respect to the 2016 ESMO-ESGO-ESTRO risk classification system, and they were analyzed with respect to differences in survival rates. Of the 2745 patients, 1743 (63.5%) were operated by laparotomy, and the remaining were operated with laparoscopy. The total numbers of high-intermediate- and high-risk endometrial cancer cases were 734 (45%) patients in the laparotomy group and 307 (30.7%) patients in the laparoscopy group. Disease-free and overall survivals were not statistically different when compared between laparoscopy and laparotomy groups in terms of low-, intermediate-, high-intermediate- and high-risk endometrial cancer. In conclusion, regardless of the endometrial cancer risk category, long-term oncological outcomes of the laparoscopic approach were found to be comparable to those treated with laparotomy. Our results are encouraging to consider laparoscopic surgery for high-intermediate- and high-risk endometrial cancer cases.

Barriers to losing weight for women attending group visits in primary care: A qualitative exploration using in-depth interviews.

BACKGROUND: Despite the accumulated evidence suggesting the positive aspects of using group visits in obesity, the number of qualitative studies that examine why and how the effects occur at an individual level is limited. OBJECTIVES: This qualitative study aimed to explore the experiences and perspectives of women who participated in group visits and had different weight loss outcomes in the programme. METHOD: Purposive maximum variation sampling was performed. Data collection and analysis were performed iteratively, and the data saturation method was used as a guideline for sample size. All participants who completed the group visits were approached, and finally, 20 individuals were included in the study. Semi-structured in-depth interviews were audio-recorded, transcribed verbatim, and analysed thematically using a phenomenological approach. RESULTS: The mean age of the individuals was 38.5 ± 9.8 years, the education level ranged from incomplete-high school to university degree, and the weight changes were between +4.1% and -17.1%. Two main themes emerged from the thematic analysis revealing barriers: weight stigma (two sub-themes: internal and external stigma) and traumatic life events (three sub-themes: 'loss of relatives,' 'childhood traumas,' and 'conflicting intimate partner relationships'). CONCLUSION: Considering the barriers to weight loss efforts in this study, these issues need to be explicitly investigated before and during the group visits in addition to weight loss practices and behavioural changes.

Easier and more explanatory indices by integrating leukocyte lymphocyte ratio (LLR) and prognostic nutritional index (PNI) to IPS systems in cases with classical Hodgkin lymphoma.

The aim of this study is to determine the power of he international prognostic scoring systems (IPS-7 and IPS-3) and to obtain indices by integrating leukocyte lymphocyte ratio (LLR) and prognostic nutritional index (PNI) factors as prognostic indicators in cases with classical Hodgkin lymphoma (cHL). 1012 patients with cHL were evaluated with 2 different IPS-4 scores with four parameters: stage, age, hemoglobin level, and either LLR or PNI. Statistical package SPSS v 22.0 was used. Two different Cox regression models were obtained for OS and PFS. Model 1 showed LLR ≥ 5,8 as the highest risk for OS and anemia as the highest risk for PFS. Model 2 showed PNI ≤ 45,2 as the highest risk for OS and anemia as the highest risk for PFS. IPS-4 scores obtained by integrating either LLR or PNI to IPS-3 integration of a biologic parameter either LLR or PNI need to be determined with clinical risk scoring parameters.

Efficacy and Safety of Trastuzumab Emtansine in Her2 Positive Metastatic Breast Cancer: Real-World Experience.

AIM: The aim of this study is to evaluate the efficacy and toxicity of trastuzumab emtansine (T-DM1) in cases with metastatic breast cancer (mBC) in different lines of treatment. METHOD: Retrospective analysis of T-DM1 results of human epidermal growth factor receptor 2 (Her2) positive 414 cases with mBC from 31 centers in Turkey. FINDINGS: Except 2, all of the cases were female with a median age of 47. T-DM1 had been used as second-line therapy in 37.7% of the cases and the median number of T-DM1 cycles was 9. Progression-free survival (PFS) and overall survival (OS) times were different according to the line of treatment. The median OS was found as 43, 41, 46, 23 and 17 months for 1st, 2nd, 3rd, 4th and 5th line, respectively (p = 0.032) while the median PFS was found as 37, 12, 8, 8 and 8 months, respectively (p = 0.0001). Treatment was well tolerated by the patients. The most common grade 3-4 adverse effects were thrombocytopenia (2.7%) and increased serum gamma-glutamyl transferase (2%). DISCUSSION: The best of our knowledge this is the largest real-life experience about the safety and efficacy of T-DM1 use in cases with mBC after progression of Her2 targeted treatment. This study suggests and supports that T-DM1 is more effective in earlier lines of treatment and is a reliable option for mBC.

IPS-3 Validation in 1012 cases with classical hodgkin lymphoma.

The aim of this study is to validate the IPS-3 scoring system as a prognostic indicator in 1012 patients with advanced stage classical Hodgkin Lymphoma (cHL) treated by doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD). According to the IPS-3 scoring system only 3.5 % had high risk and 50.8 % had low risk disease disease and 45.8 % of the cases had intermediate risk disease. Each factors of IPS-7 and IPS-3 scoring systems (age, sex, stage hemoglobin, albumin, lymphocyte count and white cell count) were found to be significant for overall survival (OS) and progression free survival (PFS) according to univariate analyses. Two different multivariate Cox analyses were performed for OS and PFS including the IPS-3/ IPS-7 scoring system parameters. Among 7 risk factors of IPS scoring system, gender and albumin were not found as independent risk factors for both OS and PFS according to cox regression model. But all parameters such as age, stage and hemoglobin those included in IPS-3, were found to be independent significant risk factors for both models obtained for OS and PFS. The results of the study shows that the IPS-3 scoring system can be used as a prognostic indicator in ABVD treated patients in every day practice which is more easily calculate according to the IPS-7.

Prognostic significance of EGFR, MUC1 and PD-L1 expressions in cases with triple negative breast cancer.

PURPOSE: Twenty percent of the breast cancers are triple negative (TNBC). Despite the impressive progression in the biology of this subgroup, data is limited as compared to hormone and/or HER2 positive cases. Thus, the aim of this study was to detect the expression levels and to identify the prognostic values of MUC1, EGFR and PD-L1 in TNBC. METHODS: MUC1, EGFR and PD-L1 expressions were detected by immunohistochemistry in 97 cases with TNBC. Associations between clinical and histopathological parameters with overall survival (OS) and progression-free survival (PFS) were analyzed using the Kaplan-Meier method and compared by the log-rank test. Prognostic effects were analyzed by Cox proportional hazard models. RESULTS: During a median follow-up of 93 months (0.6-168.7) the mean PFS was 110.1 and OS was 121.8 months. Tumor diameter (T), involved lymph node status (N) and TNM were found to be prognostic for PFS and OS. PD-L1 in microenvironment (PD-L1 ME) and EGFR expression were found to be associated with longer PFS and OS, but MUC1 and tumor PD-L1 (PD-L1 TM) expressions were not. All combined analyses showed that in the subgroups of MUC1, PD-L1 TM or ME positive, EGFR expression was correlated with longer PFS and OS than those who were not. Older age (≥70 years), T and N status and also EGFR expression were found to be independent prognostic factors for OS in Cox regression analysis. CONCLUSION: EGFR expression was found to be one of the most important prognostic factors in addition to T and N status in cases with TNBC.

Changes on Hepatitis C virus genotype distribution in Western Turkey: Evaluation of twelve-year data.

BACKGROUND/AIMS: Hepatitis C virus (HCV) prevalence is 1% in Turkey with genotype 1 being the predominant type traditionally. However unique geographical location of Turkey and increasing human migration in the region influences the epidemiology of the infection. The aim of this study was to determine the changes in distribution of HCV genotypes and risk factors. MATERIALS AND METHODS: In this retrospective single-center study, HCV genotyping results of 558 patients were evaluated in between 2005 and 2016.Three different HCV genotyping assays were used during the 12-year study period;restriction fragment length polymorphism (RFLP), Abbott Real Time HCV Genotype II and Bosphore HCV genotyping kit. RESULTS: The most prevalent HCV genotype was genotype 1 detected in 88.4% of the patients followed by genotype 3 (5.2%),genotype 4 (2.9%),genotype 2 (2.1%), mixed genotypes (1.1%) and genotype 5 (0.3%).Genotype 1a showed an increasing prevalence.There were 19 patients (3.4%) either of foreign nationalities or Turkish citizens living abroad. Genotype 3 was the most common type among these patients which 10.3% had intravenous drug use history.Syrian migrant population differed in terms of HCV genotypes.Genotype 5 detected in two Syrian patients, which is the first report of HCV type 5 in Western Turkey. Among the HCV genotype 4 infected patients, 31.3% were Syrians. CONCLUSION: Our study showed that although genotype 1b dominance continues, the distribution and prevalence of HCV genotypes are changing in our region mainly due to migration and increase in the frequency of patients with non-traditional risk factors such as intravenous drug use. Monitoring the epidemiology of HCV genotypes may provide guidance in treatment decisions.

Clinical evaluation of injectable platelet-rich fibrin with connective tissue graft for the treatment of deep gingival recession defects: A controlled randomized clinical trial.

AIM: The aim of this study was to determine whether the combined connective tissue graft (CTG) with injectable platelet-rich fibrin (i-PRF) with coronally advanced flap (CAF) improved root coverage of deep Miller Class I or II gingival recessions compared with CTG alone with CAF. MATERIAL AND METHODS: Seventy-two patients with Miller class I and II gingival recessions were enrolled. Thirty-six patients were randomly assigned to the test group (CAF+CTG+i-PRF [700 rpm for 3 min]) or control group (CAF+CTG). Clinical evaluations were made at 6 months. RESULTS: At 6 months, complete root coverage was obtained at 88% of the sites treated with CAF+CTG+i-PRF and 80% of the sites treated with CAF+CTG. Difference between the two groups was not statistically significant. At 6 months, the recession depth (RD) reduction and increase in keratinized tissue height (KTH) of the test sites were significantly better compared with the control sites. CONCLUSIONS: According to the results, the addition of i-PRF to the CAF+CTG treatment showed further development in terms of increasing the KTH and decreasing RD. However, this single trial is not sufficient to advocate the true clinical effect of i-PRF on recession treatment with CAF+CTG and additional trials are needed.

Mannose-Binding Lectin 2 Gene Polymorphism in PANDAS Patients.

INTRODUCTION: Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a subgroup of obsessive-compulsive disorder (OCD), has received much attention even though the specific underlying mechanisms remain unknown. Mannose-binding lectin (MBL) is a key factor in the innate immune response. The aim of this study was to investigate the role of MBL2 gene polymorphisms in pediatric OCD patients diagnosed as PANDAS, PANDAS-Variant and non-PANDAS. METHODS: The study included 102 pediatric OCD patients (59 [57.8% ] PANDAS, 20 [19.6% ] non-PANDAS, and 23 [22.5% ] PANDAS-Variant) and 60 healthy controls. Polymorphisms at codon 52, 54 and 57 of the MBL2 gene were investigated. RESULTS: Codon 54 polymorphism and any variant of MBL2 gene were significantly more frequent in the OCD group than in the control group (OR=2.97, 95% CI: 1.26-6.97; and OR=2.66, 95% CI: 1.32-5.38, respectively). According to regression analysis, the presence of any variant of MBL2 gene was found in 14.50-fold increased frequency in the PANDAS subgroup compared with the non-PANDAS subgroup (95% CI: 2.49-84.19). CONCLUSIONS: Our findings support an association between MBL2 genotypes and pediatric OCD, particularly PANDAS-OCD.

Assessment of potential predictive value of peripheral blood inflammatory indexes in 26 cases with soft tissue sarcoma treated by pazopanib: a retrospective study.

PURPOSE: The aim of this study was to evaluate the prognostic and predictive value of neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (DNLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) in soft tissue sarcoma (STS) cases treated with pazopanib. MATERIALS AND METHODS: The study population included 26 STS cases treated with pazopanib for at least 3 months. NLR, DNLR, LMR, and PLR were evaluated at baseline, and at third month of therapy and also compared with response to pazopanib. Median measurements were taken as cutoff for NLR (4.8), DNLR (3.1), LMR (3.6), and PLR (195). The associations between these cutoff values and survival times (progression-free survival [PFS] and overall survival [OS]) were assessed by Kaplan-Meier curves and Cox proportional models. RESULTS: Patients with low pretreatment NLR and DNLR had longer OS (P=0.022, P=0.018), but low PLR was found to be associated only with longer OS. Additionally, decrease in NLR and DNLR after 3 months of therapy as compared with pretreatment measurements was found to be associated with an advantage for OS (P=0.021, P=0.010, respectively) and PFS (P=0.005, P=0.001, respectively). Response to pazopanib; changes in NLR, DNLR, LMR, and PLR; and >3 metastatic sites were found to be independent risk factors in univariate analysis, but NLR was the only independent risk factor in multivariate analysis. CONCLUSION: Low pretreatment and decrease in NLR and DNLR values, and regression/stable disease after 3 months of pazopanib are predictive factors for longer OS and PFS.

Laparoscopic surgery for low, intermediate and high-risk endometrial cancer.

OBJECTIVE: The aim of the present study was to compare the long-term outcomes of the laparotomy (LT) and laparoscopic surgery and to evaluate the results according to low, intermediate, and high-risk groups of endometrial cancer (EC). METHODS: We identified 801 patients with EC and these patients were classified as group 1, who underwent LT (n=515); and group 2, who underwent laparoscopy (LS) (n=286). Patient's demographics, clinical characteristics such as stage, grade, histopathologic type, lymphovascular space invasion, myometrial invasion, lymph node involvement, and risk groups, peri- and post-operative outcomes, and survival outcomes were compared between the groups according to risk classification. Survival outcomes were assessed using Kaplan-Meier method. RESULTS: The demographic characteristics of both groups were similar except age. Shorter hospital stay and fewer complications were observed in group 2. The overall survival (OS) were similar in the low, low-intermediate, high-intermediate and high-risk groups (p=0.269, 0.476, 0.078, and 0.085; respectively) for LS compared to LT. The covariate analysis revealed that the death and recurrence risks were approximately twice higher in the LT group than in the LS group (odds ratio [OR]=1.9; 95% confidence interval [CI]=1.2-3.1 for OS; OR=2.0; 95% CI=1.2-3.3 for disease-free survival). CONCLUSION: The results of our study support the well-known positive aspects of LS as well as safe and effective use in cases of intermediate and high-risk EC.

The frequency of diastolic dysfunction in patients with sarcoidosis and it's relationship with HLA DRB1* alleles.

BACKGROUND: Impaired systolic function is common in sarcoidosis however the frequency of diastolic dysfunction (DD) and it's possible genetic basis has not been fully elucidated yet. The aim of this study is to evaluate the frequency of left ventricular DD(LVDD) and right ventricular DD(RVDD) and it's possible relationship between Human Leukocyte Antigen(HLA)-DRB1* alleles in patients with sarcoidosis. METHODS: Seventy seven patients (51 females, mean age 41.1±8.2yrs) without known sarcoid related or any other structured heart disease and 77 healthy controls with a similar age and gender (38.7±7.8yrs,51 females) were included in the case control study. DD was diagnosed with echocardiography. RVDD was defined as early(E)/late(A) ratio<1 or >2 on tricuspit valve. LVDD was defined as E/A ratio<1 or >2 on mitral valve, with isovolumetric relaxation time(IVRT)>90 miliseconds(msn) or deceleration rate of early diastolic flow(Edec)>220msn respectively. All patients were HLAtyped with the Sequence Specific Oligonucleotide Probe(SSOP) method. RESULTS: The frequencies of LVDDs and RVDDs were significantly higher in sarcoidosis patients than the controls (26.0% vs. 2.6% for LVDD; and 42.9% vs. 18.2% for RVDD)(p<0.05). No significant difference was found in patients according to the presence of RVDD and LVDD in terms of age, gender or respiratory function test parameters. Although the frequency of HLA DRB1* alleles were comparable among patients with RVDD, HLA DRB1*14 alleles were more frequent in patients with LVDD. CONCLUSIONS: Biventricular DD is common in patients with sarcoidosis without manifest cardiac involvement. HLA DRB1*14 allele seems to be related with LVDD in this study population.
