    ObjectivePeripartum cardiomyopathy (PPCM) diagnosis made by excluding identifiable causes of heart failure (HF) and occurs end of the pregnancy or during the postpartum period of five months. It presents a clinical HF spectrum with left ventricular systolic dysfunction. BackgroundThe purpose of this study is to retrospectively evaluate the clinical characteristics, cardiac magnetic resonance (CMR) imaging features, and end-points consisting of left ventricle recovery, left ventricular assist device implantation, heart transplantation, and all-cause mortality. MethodOutpatient HF records between 2008 to 2021 were screened. Thirty-seven patients were defined as PPCM. Twenty-five patients had CMR evaluation at the time of diagnosis, and six patients were re-evaluated with CMR. ResultsThe mean age was 30.5 +/- 5.6 years, and the mean LVEF was 28.2% +/- 6.7%. In 13(35.7%) patients, LVEF recovered during the follow-up course. The median recovery time was 281(IQR [78-358]) days. LVEF on CMR was 35.3 +/- 10.5, and three patients exhibited late gadolinium enhancement(LGE) patterns. Sub-endocardial and mid-wall uptake pattern types were detected. 18(75%) patients met the Petersen left ventricle non-compaction cardiomyopathy(LVNC) criteria. Patients with NC/C ratio lower than 2.3 had lower LVEDVi and LVESVi (124.9 +/- 35.4, 86.4 +/- 7.5, p = .003; 86.8 +/- 34.6, 52.6 +/- 7.6, p = .006), respectively. The median follow-up time was 2129 (IQR [911-2634]) days. The primary endpoint-free 1-year survival was 88.9% (event rate 11.1%), and 5-year survival was 75.7% (event rate 24.3%). ConclusionIn a retrospective cohort of PPCM patients, 35.7% of patients' LVEF recovered, and the primary end-point of free-5-year survival was 75%. Twenty-five patients were assessed with CMR; three of four met the Petersen CMR-derived LVNC at initial evaluation

    Aims Left ventricular non-compaction cardiomyopathy (LVNC) is a poorly understood entity resulting in heart failure. Whether it is a distinct form of cardiomyopathy or an anatomical phenotype is a subject of discussion. The current diagnosis is based on morphologic findings by comparing the compacted to non-compacted myocardium. The study aimed to compare demographic and prognostic variables of patients with dilated cardiomyopathy (DCM) and LVNC. Emphasis was given to cardiac magnetic resonance (CMR) imaging analysis. Data on survival were also assessed. Methods and results We retrospectively evaluated the characteristics and outcomes of 262 non-ischaemic cardiomyopathy patients with LVNC and DCM phenotypes. Petersen's CMR criteria of non-compacted to the compacted myocardial ratio 2.3 were used to diagnose LVNC. The primary endpoint was a composite endpoint of major adverse cardiovascular events comprising cardiovascular-related death, left ventricular assisted device implantation, or heart transplantation. A total of 262 patients with CMR data were included in the study. One hundred fifty-five patients who fulfilled CMR criteria were diagnosed as LVNC. CMR findings revealed that LVNC patients had higher left ventricular end-diastolic (137.2 +/- 51.6, 116.8 +/- 44.6, P = 0.002) and systolic volume index (98.4 +/- 49.5, 85.9 +/- 42.7, P = 0.049). Cardiac haemodynamics, cardiac output (5.61 +/- 2.03, 4.96 +/- 1.83; P = 0.010), stroke volume (73.9 +/- 28.8, 65.1 +/- 25.1; P = 0.013), and cardiac index (2.85 +/- 1.0, 2.37 +/- 0.72; P 0.0001), were higher in LVNC patients. Of all the 249 patients, 102 (40.9%) patients demonstrated late gadolinium enhancement (LGE). According to Petersen's criteria, the Kaplan-Meier survival outcome did not reveal significant differences (hazard ratio [HR]: 1.53, 95% confidence interval [CI]: [0.89-2.63], P = 0.11). The presence or pattern of LGE did not show significant importance for endpoint-free survival. Most of the sub-epicardial LGE pattern was found in LVNC patients (94.4%). When receiver operator characteristics analysis was applied to NC/C ratio to discriminate the primary endpoint, a higher NC/C ratio of 2.57 was associated with adverse events (HR: 1.90, 95% CI: [1.12-3.24], P = 0.016). Conclusions Our study questions the criteria being used for the diagnosis of LVNC. Further evaluation of CMR variables and association of these findings with demographic variables and survival is mandatory

    Farmers' Preferences for Organic Milk Production in Izmir, Turkey

    This study was conducted to determine farmers' preference for organic milk production and the factors influencing the degree of farmer preferences in Turkey. The data were obtained from a survey of 96 farmers in Izmir, Turkey. The study was conducted using a two-stage methodology. First, fuzzy pair-wise comparison was applied to calculate the degree of preference. Five important factors were hypothesized to affect the transition to organic milk production; the producers were asked to make pair-wise comparisons among these factors. The reasons for farmers' preferences were then determined using a seemingly unrelated regression. The results showed that the most important factors for producers are health of consumer and guarantee of sale. Preferences for these factors are mainly influenced by producers' level of education and farm size

    Determination of myocardial scar tissue in coronary slow flow phenomenon and the relationship between amount of scar tissue and nt-probnp [Determinação do tecido cicatricial do miocárdio no fenômeno de fluxo coronário lento e a relação entre a quantidade de tecido cicatricial e o nt-probnp]

    Background: Pathophysiology and prognosis are not clearly determined in patients with the coronary slow flow phenomenon (CSFP). These patients present with various clinical conditions ranging from being asymptomatic to being admitted with sudden cardiac death. Objectives: We aimed at assessing the findings of late gadolinium enhancement (LGE) in cardiac magnetic resonance imaging (CMR) as an indicator of myocardial fibrosis. We also aimed at determining the relationship between the presence of myocardial fibrosis and NT-proBNP levels in patients with CSFP in the left anterior descending coronary artery (LAD). Methods: A total of 35 patients were enrolled within an age range of 31-75. The study patients (n=19) had normal epicardial coronary arteries at angiography, but they presented with CSFP in the LAD. The control group patients (n=16) had normal epicardial coronary arteries and TIMI scores at normal levels in angiography. In both groups, the patients were examined with CMR for the presence of myocardial fibrosis. In addition, plasma NT-proBNP levels were measured. A p-value < 0.05 was considered significant. Results: The rate of myocardial fibrosis was significantly higher in CMR in the patients with CSFP (p=0.018). A variable amount of myocardial scar tissue was detected at the left ventricular apex in 7 patients and at the inferior and inferolateral regions in 3 patients. There was no difference in the level of NT-proBNP in patients with CSFP. However, the NT-proBNP levels were higher in patients with CSFP, who had scar tissue in CMR (p=0.022). Conclusions: In conclusion, LGE in CMR showed that ischemic myocardial scarring may exist in patients with CSFP. These results indicate that CSFP may not always be innocent
