The newly recognized ataxia-ocular apraxia 1 (AOA1; MIM 208920) is the most frequent cause of autosomal recessive ataxia in Japan and is second only to Friedreich ataxia in Portugal. It shares several neurological features with ataxia-telangiectasia, including early onset ataxia, oculomotor apraxia and cerebellar atrophy, but does not share its extraneurological features (immune deficiency, chromosomal instability and hypersensitivity to X-rays). AOA1 is also characterized by axonal motor neuropathy and the later decrease of serum albumin levels and elevation of total cholesterol. We have identified the gene causing AOA1 and the major Portuguese and Japanese mutations. This gene encodes a new, ubiquitously expressed protein that we named aprataxin. This protein is composed of three domains that share distant homology with the amino-terminal domain of polynucleotide kinase 3'- phosphatase (PNKP), with histidine-triad (HIT) proteins and with DNA-binding C2H2 zinc-finger proteins, respectively. PNKP is involved in DNA single-strand break repair (SSBR) following exposure to ionizing radiation and reactive oxygen species. Fragile-HIT proteins (FHIT) cleave diadenosine tetraphosphate, which is potentially produced during activation of the SSBR complex. The results suggest that aprataxin is a nuclear protein with a role in DNA repair reminiscent of the function of the protein defective in ataxia-telangiectasia, but that would cause a phenotype restricted to neurological signs when mutant.

Familial amyloidotic polyneuropathy (FAP-type I) was first described in Portugal by Andrade in 1952, a time when 54 among 64 patients (belonging to 25 families) originated from Póvoa do Varzim or its surrounding districts. Since then, a total of 1,233 patients, belonging to 489 pedigrees (so far unrelated), have been diagnosed at Centro de Estudos de Paramiloidose, Porto, Portugal. Although age-of-onset showed a wide range (17 to 78 years), 87% of these 1,233 patients developed symptoms before 40 years of age (mean 33.5, SD 9.4 years). Among all patients, 432 belong to 140 families originating from the area of Póvoa do Varzim/Vila do Conde, 330 of whom lived in that area at the time of diagnosis; age-of-onset was, on average, lower than in the overall group of patients (mean 31.1, SD 6.7 years), and no patient had onset after 57 years (versus 3.3% in the global sample). As in previous studies, women were found to have a later onset (33.7) than men (29.0) years. In 1991, the crude prevalence rate was 90.3 x 10(-5) (one in every 1,108 inhabitants), and the frequency of gene carriers was estimated to be 186 x 10(-5) (one in every 538); about 48.4% of these carriers had manifested symptoms by 1991. Female patients had a significantly higher number of children (mean 3.7, SD 2.6) than male patients (mean 2.7, SD 2.1) and the length of their reproductive period (mean 8.4, SD 5.8 yr) was also greater than for men (mean 5.6, SD 4.4 yr). Altogether, the 122 patients who ever reproduced contributed 457 children to the next generation, a mean fertility of 3.7. Further studies using a control groups may answer the question of whether this is the result of a specific high fertility of these patients or just their belonging to a population in natural expansion.

The results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe. EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events.

The relationship between religious involvement and forgiveness was assessed in three samples of Western Europeans living in a social environment dominated by the Catholic tradition. The samples comprised nonbelievers/nonattendees, believers/nonattendees, believers/regular attendees, and religious people. Age and religious involvement were shown to affect the willingness to forgive in an interactive way: The effect of religious involvement was stronger for the elderly group. We also found that what made the difference in the willingness to forgive was mainly the social commitment to religion (attendance in church and the taking of vows), not mere personal beliefs. In addition, age and religious involvement were found to affect blockage towards forgiveness in an additive way.
