Some hazards of invasive cardiology.

Since the introduction of cardiac catheterization by Andre Cournand and Dickinson Richards, the valuable diagnostic and therapeutic device has encouraged many action-minded physicians to use cardiac catheterization to develop a new specialty, invasive cardiology. The data to be presented here derive from a catastrophe that occurred during an invasive treatment of a 54-year-old man who had experienced an ordinary myocardial infarction.     

Anxiety,depression, and health-related quality of life in aging people living with HIV compared to diabetes patients and patients with minor health conditions: a longitudinal study

HIV infection has evolved from a fatal to a treatable condition, leading to an increase in the rate of elderly People Living with HIV (PLWH). However, little is known about the psychosocial burden of elderly PLWH. Thus, the aim of this longitudinal multi-center cohort study was to investigate whether elderly PLWH experience more anxiety and depression and reduced health related quality of life (HRQOL) compared to elderly patients with other chronic conditions. PLWH were compared to diabetes patients (DM) and patients with minor health conditions (MHC), e.g. patients with hypertension or allergic conditions. All patients were over 50 years old. Anxiety and depression (HADS) as well as HRQOL (SF-36) were assessed at baseline and after 12 months. 218 PLWH, 249 DM and 254 MHC were included. At baseline, the study groups did not differ in anxiety, depression, and physical HRQOL. However, PLWH indicated lower mental HRQOL than DM and MHC patients (p = 0.001). We did not obtain any moderating effects showing a differential effect of patient characteristics on anxiety, depression, and HRQOL in the three patient groups. At follow-up, the level of anxiety, depression, and HRQOL did not change significantly. The prevalence of anxiety ranged between 27 and 35%, and that of depression between 17 and 28%. Thus, the results of our investigation tentatively suggest that the psychosocial adaptation to HIV among elderly PLWH resembles those of other chronic diseases. There may be some subtle impairments, though, as PLWH experienced lower mental HRQOL.     

Dyslexia, dysnomia, and lexical retrieval: a longitudinal investigation

Results from a 3-year longitudinal investigation of confrontation naming in 98 children (75 average readers, 14 severely impaired readers, 9 bilingual readers) indicate: kindergarten performance on confrontation naming predicts Grade 2 reading performance, particularly reading comprehension; confrontation naming differentiates average from severely impaired readers; and lexical retrieval, not vocabulary knowledge, is the major source of difference between reading groups. Findings on lexical retrieval are integrated with research on naming access speed. The implications of these results for specification of dyslexia subgroups are discussed.
