I don't know how I feel,therefore I act: Alexithymia,urgency, and alcohol problems

This study examined the relationships between alexithymia, impulsivity, and alcohol use and related problems. The sample consisted of 429 undergraduate students who reported drinking alcohol at least once in the past 3 months. Negative urgency mediated the relationship between alexithymia and alcohol-related problems, whereas positive urgency mediated the relationship between alexithymia and alcohol consumption. In addition, positive urgency moderated the relationship between alexithymia and alcohol-related problems, increasing the strength of this association. These results indicate distinct relationships between alexithymia and negative urgency and positive urgency in predicting alcohol consumption and related problems. The findings of this research contribute to the body of the literature on alexithymia, self-regulation, and etiology of alcohol misuse and related consequences. Furthermore, the findings of the current study provide support for the importance of emotion identification and expression skills training in substance abuse treatment.     

Comparative localization of myocardial ischemia by exercise electrocardiography and myocardial perfusion SPECT

BACKGROUND: Prior angiographic study has shown that the patterns of ST-segment depression during exercise do not provide localizing information of the responsible coronary lesion. However, little is known regarding the ability of exercise-induced ST-segment displacement to localize myocardial perfusion defects. METHODS AND RESULTS: We studied 552 consecutive patients without prior myocardial infarction who had reversible perfusion defect in one vascular territory on rest 201Tl/exercise 99mTc-labeled sestamibi dual-isotope myocardial perfusion single photon emission computed tomography (SPECT) and ischemic ST depression or elevation during exercise. Of these, 192 patients had angiographically documented coronary artery disease (CAD). Two hundred thirty-two patients had maximal ST depression in anterior leads, 247 patients had maximal ST depression in inferior leads, and 45 patients had similar maximal ST depression in both anterior and inferior leads. Twenty-eight (5%) patients had ST elevation with absent Q waves. In patients with maximal ST depression in anterior leads, perfusion defects were found in the territory of the left anterior descending coronary artery (LAD) in 30%, in the territory of the right coronary artery (RCA) in 52%, and in the territory of the left circumflex coronary artery (LCX) in 18%. In patients with maximal ST depression in inferior leads, perfusion defects were found in RCA territory in 44%, in the LAD territory in 42%, and in the LCX territory in 14%. Compared with exercise ST depression, the less common finding of ST elevation did provide accurate localization of perfusion defects. When ST elevation was greatest in the anterior leads, 96% of patients had LAD territory defects. When ST elevation was most prominent in the inferior leads, 100% patients had RCA territory defects. Data of coronary angiograms demonstrated that myocardial perfusion SPECT correctly identified the most stenotic coronary disease for LAD (94%), LCX (72%), and RCA (75%). CONCLUSIONS: The findings of this study indicate that the site of maximal ST-segment depression does not identify the localization of myocardial perfusion defects. However, the less common finding of exercise-induced ST-segment elevation does predict localization of myocardial ischemia.     

Acute mixed lineage leukemia and a t(6;14)(q25;q32) in two adults

Acute mixed lineage leukemia (AMLL) is a rare form of leukemia in which both myeloid and lymphoid markers are present. Few chromosome abnormalities have been identified associated with this form of leukemia. A translocation involving the long arms of chromosomes 6 and 14 was previously described in four young individuals with acute leukemia and in three of these cases the diagnosis was mixed lineage. We identified a translocation involving the same chromosomes in two additional cases of adults with AMLL. The q32 breakpoint on chromosome 14 is shared by all six cases and five out of six cases also share the q25 breakpoint on chromosome 6. The rarity of the t(6;14) and the AMLL suggests a non-random association between these two events. The near cryptic appearance of the translocation might indicate that its occurrence is underestimated.     

Neuroblastoma among children in Southern and Eastern European cancer registries: Variations in incidence and temporal trends compared to US

Neuroblastoma comprises the most common neoplasm during infancy (first year of life). Our study describes incidence of neuroblastoma in Southern–Eastern Europe (SEE), including – for the first time – the Nationwide Registry for Childhood Hematological Malignancies and Solid Tumors (NARECHEM‐ST)/Greece, compared to the US population, while controlling for human development index (HDI). Age‐adjusted incidence rates (AIR) were calculated for 1,859 childhood (0–14 years) neuroblastoma cases, retrieved from 13 collaborating SEE registries (1990–2016), and were compared to those of SEER/US (N = 3,166; 1990–2012); temporal trends were assessed using Poisson regression and Joinpoint analyses. The overall AIR was significantly lower in SEE (10.1/million) compared to SEER (11.7 per million); the difference was maximum during infancy (43.7 vs. 53.3 per million, respectively), when approximately one‐third of cases were diagnosed. Incidence rates of neuroblastoma at ages <1 and 1–4 years were positively associated with HDI, whereas lower median age at diagnosis was correlated with higher overall AIR. Distribution of primary site and histology was similar in SEE and SEER. Neuroblastoma was slightly more common among males compared to females (male‐to‐female ratio: 1.1), mainly among SEE infants. Incidence trends decreased in infants in Slovenia, Cyprus and SEER and increased in Ukraine and Belarus. The lower incidence in SEE compared to SEER, especially in infants living in low HDI countries possibly indicates a lower level of overdiagnosis in SEE. Hence, increases in incidence rates in infancy noted in some subpopulations should be carefully monitored to avoid the unnecessary costs health impacts of tumors that could potentially spontaneously regress.
