Ghost-ant: Post-embryonic development of the worker caste of Tapinoma melanocephalum (hymenoptera: Formicidae)

This study examines some aspects of the basic biology of the worldwide distributed ant Tapinoma melanocepbalum Fabricius. The number of larval instars and the growth ratio between each instar are given. We used colonies containing only queens and workers, and later removed these queens in order to estimate the production of eggs and the duration of immature development of the worker caste. Measurements of larvae cephalic capsule widths revealed that workers of the ghost-ant have four larval instars from egg-hatching to adult. The mean growth rate for the species is 1.38, in accordance with Dyar's rule. The highest egg production was 5.3±2.2 eggs/day/queen and the analysis of these brood suggested the presence of two kinds of eggs inside the colony. The development of workers from egg to adult lasted 16-52 days with the embryonic development longer than larval, prepupal or pupal stages. Despite the slow egg-laying by queens, our findings also showed that colonies of T. melanocephalum grow faster than colonies of other tramp ants.

Oral health of the elderly with Alzheimer's disease

Objective: The objective of this study was to describe the oral health of elderly people diagnosed with Alzheimer's disease (AD). Study Design: Thirty elderly subjects with AD (mild, moderate, and severe) and 30 without AD (controls) were included in the study. Volunteer-reported oral health data were collected using the General Oral Health Assessment Index (GOHAI). Demographic and oral characteristics were assessed, including the number of natural teeth; number of decayed, missing, and filled teeth (DMTF); oral health index (OHI); removable prosthesis conditions; and oral pathologies. Results: GOHAI values were similar for both groups. Compared with the controls, the subjects with AD had a higher age, DMTF, OHI, and number of oral pathologies and a lower educational level and number of natural teeth. Conclusions: Elderly subjects with AD had poorer oral health than those without the disease. Despite the positive self-perception of their oral health, the oral health of subjects with AD tended to decline as their disease progressed. © 2012 Elsevier Inc.

Mental health of the elderly: perceptions related to aging

To understand the elderly's perception of their current condition. Methodology. Study undertaken in 2012 using the qualitative method of Minayo and the thematic analysis according to Bardin's suggestions. Data were collected through semi-structured interviews that took place in the homes of the elderly people. The guiding question was: At this point in your life, how do you feel? Tell me. Results. The elderly who were satisfied stated that this was due to the good relationship with their family, spouse, to the fact of having autonomy and respect from the society. Those who were shown to be dissatisfied reported lack of family support, physical limitations imposed by age and the presence of illnesses as the main causes. Conclusion. The adult population requires the use of care technologies that cover all the stages of life, including old age. Nursing professionals should be prepared for the increasing care demand of these people.
