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.

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.

BACKGROUND: There are only a few studies about epidemiological features of acne vulgaris in the literature. The aim of this study was to analyze demographic, clinical, familial and environmental characteristics of acne, the role of diet and aggravating factors and association of these factors with acne severity. METHODS: Patients with a diagnosis of mild-moderate to severe acne were consecutively interviewed at the participating centers during the study period. RESULTS: A total of 3826 patients and 759 control patients were involved in this study. Mild acne was the most common type of acne, and most of the lesions were localized on face followed by the trunk. The severity of acne was worse in patients who had a positive family history of acne. The most common triggering factor was psychological stress. We found a positive correlation with chocolate, bread, green tea, milk, white sugar, ripe banana, ice cream, apple, orange, and red meat consumption. As we compare the acne severity according to geographical features we detected mild- moderate acne was more common in Mediterranean region and severe acne was more common in East Anatolian region. Family history positivity was more common in Aegean region and least common in Central Anatolian region. There was statistically significant relationship as we compare acne severity and dietary factors such as chocolate, dairy products such as milk, sunflower seed consumption within the geographical regions. CONCLUSIONS: This study presents the demographic and clinical characteristics of acne patients in Asian and the European parts of Turkey. We believe that this study will provide a useful overview of acne in Turkey.

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.

BACKGROUND: Plasma levels of estimated whole blood viscosity (eWBV) have been increased by endothelial inflammation. Because there were no consistent data for assessing the eWBV levels for prediction of cardiovascular event (CVE) in patients with chronic kidney disease (CKD). We aimed to investigate the relationship between plasma eWBV levels and CVEs in patients with CKD. MATERIALS AND METHODS: We conducted a prospective, cross-sectional, long-term follow-up study, assessing the relationship between plasma eWBV levels and CVE (either fatal or nonfatal) in patients with newly diagnosed CKD. We also evaluated estimated glomerular filtration rate (eGFR), pentraxin 3 (PTX3), high-sensitivity C-reactive protein (hsCRP), and flow-mediated dilatation (FMD). RESULTS: Study patients were divided into 2 groups: patients with CVE and patients without CVE. The eWBV levels were higher in patients with CVE. Additionally, PTX3 and hsCRP were higher, and FMD and eGFR were lower in patients with CVE compared to those without CVE. According to the Cox regression analysis, WBV, plasma asymmetric dimethylarginine levels, FMD, hsCRP, eGFR, systolic blood pressure, calcium, and history of diabetes were independent predictors of CVEs in patients with CKD. Kaplan Meier survival curves were generated to establish the impact of the WBV on the cumulative survival of the cohort. Patients with eWBV values higher than 5.2 centipoise (cP) had lower survival rates when compared to patients with eWBV values lower than 5.2 cP (log rank = 4.49 df = 1 P = .034). CONCLUSION: In conclusion, plasma eWBV levels may increase the presence of lower eGFR and affect CVE in patients with CKD independent of classical and unconventional risk factors.

BACKGROUND: No-reflow phenomenon is a prognostic value in ST-segment elevation myocardial infarction (STEMI). Monocyte to high density lipoprotein ratio (MHR) has recently emerged as a marker of inflammation and oxidative stress in the cardiovascular disease. PURPOSE: In this study, we aimed to investigate the relation between MHR and no-reflow phenomenon in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). MATERIAL AND METHODS: A total of 600 patients with STEMI (470 men; mean age, 62 ± 12 years) admitted within 12 hours from symptom onset were included into this study. Patients were classified into 2 groups based on postintervention Thrombolysis in Myocardial Infarction (TIMI) flow grade: no-reflow-TIMI flow grade 0, 1, or 2 (group 1); angiographic success-TIMI flow grade 3 (group 2). RESULTS: According to admission whole-blood cell count results, the patients in the no-reflow group had significantly higher monocyte count and MHR values when compared with those of the reflow patients. After multivariate backward logistic regression, MHR remained independent predictors of no reflow after pPCI. Adjusted odds ratios were calculated as 1.09 for MHR (P< .001; confidence interval [CI], 1.07-1.12). Receiver operating characteristic curve analysis suggested that the optimum MHR level cutoff point for patients with no-reflow was 22.5, with a sensitivity and specificity of 70.2% and 73.3%, respectively (area under curve, 0.768; 95% CI, 0.725-0.811). CONCLUSION: In conclusion, MHR levels are one of the independent predictors of no reflow in patients with STEMI after pPCI.

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.

No-reflow is of prognostic value in ST-segment elevation myocardial infarction (STEMI) but has not been extensively investigated in young patients. Young patients with STEMI admitted within 12 hours from symptom onset and treated by primary percutaneous coronary intervention (pPCI) were recruited. Patients were classified into 2 groups based on postintervention thrombolysis in myocardial infarction (TIMI) flow grade; no-reflow: TIMI flow grade 0, 1 or 2 (group 1; n = 27; 21 men, mean age: 42 ± 4 years); and angiographic success: TIMI flow grade 3 (group 2; n = 118; 110 men, mean age: 43 ± 4 years). Adjusted odds ratios were 13.79 for female gender (P < .001; confidence interval [CI] = 1.88-101.26), 2.09 for pain to balloon time (P < .017; CI = 1.14-3.812), 12.29 for high TIMI thrombus grade (P = .012; CI = 1.74-86.94), 0.04 for tirofiban use (P < .001; CI = 0.01-0.22), 5.19 for mean platelet volume (MPV; P < .001; CI = 2.44-11.01), and 1.008 for platelet-lymphocyte ratio (PLR; P = .034; CI = 1.001-1.016). In conclusion, female gender, pain to balloon time, high TIMI thrombus grade, tirofiban, MPV, and PLR were independent predictors of no-reflow in young patients with STEMI after pPCI.

BACKGROUND: The red cell distribution width-platelet ratio (RPR), a novel inflammatory marker is currently used to predict inflammation in chronic diseases. It may be associated with adverse outcomes among artery disease but its prognostic value in ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) has not been fully investigated. There is no data regarding the association between RPR and in-hospital major adverse cardiovascular events (MACEs). This study evaluated the relations between pre-procedural RPR and the in-hospital and long-term outcomes in STEMI patients undergoing primary PCI. METHODS: This study included 580 STEMI patients (77% men, mean age: 59 ± 12 years). The patients were divided into two groups according to thrombolysis in myocardial infarction (TIMI) flow grades after primary PCI. No-reflow was defined as a post-PCI TIMI flow grade of 0, 1 or 2 (group 1). Angiographic success was defined as TIMI flow grade 3 (group 2). RESULTS: Whole blood cell count, neutrophil and lymphocyte percentages, red cell distribution width, platecrit, neutrophil-lymphocyte ratio (NLR) and RPR values were higher among patients with no-reflow. On multivariate analysis, pain to balloon time, multivessel disease, TIMI thrombus grade, tirofiban, aspirin, previous coronary artery disease, NLR, platecrit and RPR remained independent predictors of no-reflow after primary PCI. Patients in no-reflow group tended to be higher percent in-hospital MACE, including nonfatal myocardial infarction and cardiovascular mortality compared to the reflow patients. CONCLUSIONS: Admission NLR, platecrit and RPR are independent correlates of no-reflow and in-hospital MACEs among patients with STEMI undergoing primary PCI.

BACKGROUND: Atrial electromechanical delay (AEMD) times were considered independent predictors of cardiovascular morbidity among the general population. We aimed at evaluating AEMD times and other risk factors associated with 2-year combined cardiovascular (CV) events in HD patients. MATERIAL AND METHODS: Sixty hemodialysis (HD) and 44 healthy individuals were enrolled in this prospective study. Echocardiography was performed before the mid-week dialysis session for HD patients. Data were expressed as mean ± SD. Spearman test was used to assess linear associations. Survival was examined with the Kaplan-Meier method. Multivariate Cox regression analysis was used to determine the predictors of combined CV events in this cohort. RESULTS: At the beginning of the study, left intra-atrial-AEMD times were significantly longer in HD patients compared to the left intra-atrial-AEMD times in healthy individuals. After 24 months, 41 patients were still on HD treatment and 19 (31.6%) had died. Serum triglyceride, total cholesterol and albumin were found to be higher and C-reactive protein (CRP) levels, left intra-atrial EMD time (LIAT) and interatrial EMD times were found to be lower in survived HD patients. With the cut-off median values of 3.5 g/dl for albumin, 0.87 mg/dl for CRP, 157 mg/dl for total cholesterol and 151 mg/dl for triglyceride, the Kaplan-Meier curves demonstrated significant differences in terms of all-cause mortality. We also demonstrated the Kaplan-Meier survival curves of HD patients according to tertile values of LIAT. Cox regression analysis revealed that increased CRP and higher LIAT were found to be independent predictors of combined CV events. CONCLUSIONS: Increased LIAT and inflammation were found to be closely associated with 2 years combined CV events and all-cause mortality in HD patients.

BACKGROUND: Obstructive sleep apnea (OSA) leads to intermittent hypoxia, activation of the sympathetic nervous system, and eventually cardiovascular morbidity. Alterations in autonomic nervous system (ANS) tone and reflexes are likely to play major roles in OSA-associated morbidities, and have been identified in a subset of children with OSA. OBJECTIVES: To evaluate whether pupillometry, a noninvasive and rapid bedside test for the assessment of autonomic nervous system dysfunction (ANS), would detect abnormal ANS function in children with OSA. METHODS: Children ages 2-12 years underwent polysomnography (PSG), and were divided based on PSG findings into two groups; Habitual Snorers (HS; AHI < 1 h/TST, n = 17) and OSA (AHI > 1 h/TST, n = 49), the latter then sub-divided into AHI severity categories (>1 but <5, >5 but <10, and >10 h/TST). Pupillometric measurements were performed during the clinic visit in a dark room using an automated pupillometer device. RESULTS: A total of 66 subjects with a mean age of 7.3 ± 2.6 years were recruited. There were no statistically significant differences between any of the groups, even when comparing severe OSA (n = 15) and HS in any of the measures related to pupillary reflexes. However, mild, yet significant increases in systolic blood pressure and morning plasma norepinephrine levels were detected in the severe OSA group. CONCLUSION: Although ANS perturbations are clearly present in a proportion of children with OSA, particularly those with severe disease, pupillary responses do not appear to provide a sensitive method for the detection of ANS dysfunction in OSA children.

OBJECTIVE: To explore the causes and prevalence of visual impairment in young Turkish men. METHODS: The health examination data of the candidates that are saved in National Defense Ministry of Turkey was used. The data of the candidates examined between 1 January 2009 and 31 December 2011 were evaluated. The total number of the candidates was 1777500. The candidates requiring advanced examination are referred to secondary and tertiary examination hospitals. RESULTS: Fourteen thousand eight hundred sixty two(14862) out of 1777500 candidates were declared unfit for compulsory military service because of ophthalmic causes. The prevalence of ophthalmologic diseases causing unfitness for military service was found 0.746% for 2009, 0.871% for 2010 and 0.889% for 2011. These included high refractive errors which was the most frequent pathology causing unfitness (40.1%). Nonsurgical retina, vitreous and optic nerve diseases were the most frequent cause of visual impairment (0.212%). Corneal and lens pathologies were the second most frequent cause of blindness (0.101%). CONCLUSIONS: The data bank in National Defense Ministry analyzed in this study is not directly intended to explore the causes and prevalence of visual impairment in Turkey. However this study gives considerable knowledge about the causes and prevalence of visual impairment in Turkey.

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.

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.

BACKGROUND AND OBJECTIVES: The role of reversibility of nontraditional risk factors, like inflammation and CKD-mineral bone disorder, in the reduction of cardiovascular risk after renal transplantation is still scarcely defined. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: The longitudinal relationship between C-reactive protein, CKD-mineral bone disorder biomarkers, and intima media thickness was investigated in a series of 178 patients (age=32±10 years) with stage 5 CKD maintained on chronic dialysis who underwent echo-color Doppler studies of the carotid arteries before and after renal transplantation. Smokers and patients with diabetes were excluded from the study. In all patients, immunosuppression was performed by a standard regimen on the basis of calcineurin inhibitors. Healthy controls were specifically selected to match the age and sex distribution of the patients. Biochemical and intima media thickness assessments were repeated 6 months after transplantation. RESULTS: Before transplantation, intima media thickness in patients with stage 5 CKD on dialysis (average=0.9±0.2 mm) was higher (P<0.001) than in well matched healthy controls (0.6±0.1 mm) and reduced substantially (-22%; 95% confidence interval, -24% to -20%) after transplantation (P=0.001). GFR (multivariable-adjusted ß=0.23; P<0.001), C-reactive protein (ß=0.15; P<0.001), and fibroblast growth factor 23 (ß=0.28; P<0.001) were the strongest independent correlates of intima media thickness before transplantation. Similarly, longitudinal changes in the same biomarkers were the sole independent correlates of simultaneous changes in intima media thickness (C-reactive protein: ß=0.25; fibroblast growth factor 23: ß=0.26; P<0.001 for both) after renal transplantation. The evolution of intima media thickness after transplantation was largely independent of classic risk factors, including BP, LDL cholesterol, and insulin resistance, as measured by homeostatic model assessment. CONCLUSIONS: Intima media thickness improves after renal transplantation. Such an improvement associates with parallel changes in serum C-reactive protein and fibroblast growth factor 23. These observations are in keeping with the hypothesis that the decline in cardiovascular risk after transplantation, in part, depends on partial resolution of nontraditional cardiovascular risk factors, like inflammation and CKD-mineral bone disorder.

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.

BACKGROUND: The clinical importance of F-wave inversion in the diagnosis of Carpal Tunnel Syndrome (CTS) is not yet well known. OBJECTIVE: This study aims to investigate the value of F-wave inversion in diagnosing CTS, and to evaluate the relationship of F-wave inversion with age, gender, diabetes mellitus, body mass index (BMI), wrist or waist circumferences. METHODS: Patients (n=744) who were considered to have CTS with clinical findings were included in the study. In order to confirm the diagnosis of CTS, standard electrophysiological parameters were studied with electroneuromyography. In addition, median nerve F-wave measurements were done and we determined if F-wave inversion was present or not. Sensitivity and specificity of F-wave inversion were investigated for its value in showing CTS diagnosed by electrophysiological examination. RESULTS: CTS diagnosis was confirmed by routine electrophysiological parameters in 307 (41.3%) patients. The number of the patients with the presence of F-wave inversion was 243 (32.7%). Sensitivity of F-wave inversion was found as 56% and specificity as 83.8%. BMI and wrist circumference values were significantly higher in patients with F-wave inversion present than those with F-wave inversion absent (p=0.0033, p=0.025 respectively). CONCLUSIONS: F-wave inversion can be considered as a valuable electrophysiological measurement for screening of CTS.

AIM: Lipids are the main source of calories and considered very important in infant growth. We aimed to compare fatty acid composition of term and preterm breast milk. This is the first study that compares the fatty acid levels of preterm and term breast milk in Turkish women. MATERIALS AND METHODS: Breast milk samples were obtained from mothers of term (n = 15) and preterm (n = 15) infants on postnatal days 3, 7, and 28. Fatty acid composition of human breast milk was determined longitudinally by gas-chromatography/mass spectrometry. RESULTS: There Were 31 fatty acids measured in the milk samples. In the first month, 17 fatty acid levels had significant differences. In group comparison, some fatty acids (C14:0, C16:0, C18:1 and C20:5) had significantly increased in the preterm group (P = 0.041, P = 0.046, P = 0.027, P = 0.033, respectively), whereas myristoleic acid (C14:1) and eicosanoic acid (C20:0) had significantly increased in the term group (P = 0.015, P = 0.048, respectively). CONCLUSION: Term and preterm milk have different compositions of fatty acids. Breast milk composition changes over time. As a general conclusion, breast milk provides the lipid requirements of infants.

BACKGROUND: To compare the knowledge and preference of preconceptional contraception to future postpartum contraceptive method choice in high-risk pregnancies. RESEARCH QUESTION: Does a high-risk pregnancy condition affect future postpartum contraceptive method choice? METHOD: Women hospitalised at the High Risk Pregnancy unit of a tertiary research and training hospital were asked to complete a self-reported questionnaire that included demographic characteristics, presence of unintended pregnancy, contraceptive method of choice before the current pregnancy, plans for contraceptive use following delivery and requests for any contraceptive counselling in the postpartum period. FINDINGS: A total of 655 pregnant women were recruited. The mean age, gravidity and parity of the women were 27.48 ± 6.25 years, 2.81 ± 2.15 and 1.40 ± 1.77, respectively. High-risk pregnancy indications included 207 (31.6%) maternal, 396 (60.5%) foetal and 52 (7.9%) uterine factors. All postpartum contraceptive choices except for combined oral contraceptives (COCs) usage were significantly different from preconceptional contraceptive preferences (p<0.001). High-risk pregnancy indications, future child bearing, ideal number of children, income and education levels were the most important factors influencing postpartum contraceptive choices. While the leading contraceptive method in the postpartum period was long-acting reversible contraceptive methods (non-hormonal copper intrauterine device Cu-IUD, the levonorgestrel-releasing intrauterine system (LNG-IUS) (40%), the least preferred method was COCs use (5.2%) and preference of COCs use showed no difference between the preconceptional and postpartum periods (p=0.202). Overall 73.7% of the women wanted to receive contraceptive counselling before their discharge. CONCLUSION: A high-risk pregnancy condition may change the opinion and preference of contraceptive use, and also seems to affect the awareness of family planning methods.
