Breast cancer detection among young survivors of pediatric Hodgkin lymphoma with screening magnetic resonance imaging
BACKGROUND Female survivors of pediatric Hodgkin lymphoma (HL) who have received chest radiotherapy are at increased risk of breast cancer. Guidelines for early breast cancer screening among these survivors are based on little data regarding clinical outcomes. This study reports outcomes of breast cancer screening with MRI and mammography (MMG) after childhood HL. METHODS We evaluated the results of breast MRI and MMG screening among 96 female survivors of childhood HL treated with chest radiotherapy. Outcomes measured included imaging sensitivity and specificity, breast cancer characteristics, and incidence of additional imaging and breast biopsy. RESULTS Median age at first screening was 30 years, and the median number of MRI screening rounds was 3. Ten breast cancers were detected in 9 women at a median age of 39 years (range, 24-43 years). Half were invasive and half were preinvasive. The median size of invasive tumors was 8 mm (range, 3-15 mm), and none had lymph node involvement. Sensitivity and specificity of the screening modalities were as follows: for MRI alone, 80% and 93.5%, respectively; MMG alone, 70% and 95%, respectively; both modalities combined, 100% and 88.6%, respectively. All invasive tumors were detected by MRI. Additional investigations were required in 52 patients, (54%), and 26 patients (27%) required breast biopsy, with 10 patients requiring more than 1 biopsy. CONCLUSIONS Screening including breast MRI with MMG has high sensitivity and specificity in pediatric HL survivors, with breast cancers detected at an early stage, although it is associated with a substantial rate of additional investigations.

Screening female survivors of pediatric Hodgkin Lymphoma for breast cancer with MRI and mammography detected tumors at an earlier stage than prior studies of mammography alone, although a substantial proportion of women required additional tests for benign imaging findings. The 5-year cumulative incidence of invasive or preinvasive tumors after initiating screening was 10.8%
The outcome of peripartum cardiomyopathy patients-single center experience
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
Characteristics and long-term survival of patients with left ventricular non-compaction cardiomyopathy
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
