Immediate postnatal sucking in the rabbit: its influence on pup survival and growth.

This study was aimed at characterising the impact of immediate postnatal sucking on pup survival and development. The interactive effects of postnatal success with the day 0 weight of pups, the nest-access regimen (controlled or free) or parity of females was investigated. Pups (n = 900) were categorised according to their initial ingestion of colostrum. In primiparous does: (1) pup mortality between d0-d10 was higher for unsuccessful than for successful early suckers; (2) lighter d0-weight reduced survival for unsuccessful but not for successful pups; (3) free nest-access of females annihilated the survival advantage fostered by the initial sucking success. In secondiparous does, these impacts waned. Finally, whatever the does' parity, only d0-weight influenced pup weight-gain between d0-21. Thus, pup survival seemed to depend (at least in primiparae) on their ability to suck right after birth, and to display a pattern of energy saving without being disturbed by the females' nest entries.

Risk factors for hepatitis B virus infection in black female attendees of a sexually transmitted disease clinic.

Although recent data have supported the role of heterosexual activity in the transmission of hepatitis B virus infection in women, studies generating these data have enrolled few black women. We therefore examined black female participants attending our local health department's sexually transmitted disease clinic for the treatment of presumed uncomplicated gonorrhea in serologic and risk-factor surveys of hepatitis B virus infection. Twenty-four (17.6%) of 136 subjects tested had evidence of prior hepatitis B infection. Serologic evidence of hepatitis B infection was significantly associated with three different barometers of sexual activity that included: (1) years of sexual activity (P less than 0.005); (2) history of sexually transmitted disease (P less than 0.02); and (3) number of lifetime heterosexual partners (P less than 0.001). These data provide further support that the quantity of sexual exposure seems to be an important risk factor for hepatitis B infection in heterosexually active females.

[Neurovegetative diseases in dementia].

Dementia is the result of the dysfunction and death of cells in the central and peripheral nervous system. Of diverse etiology, these processes are insidious in their onset and are characterized by a progressive neural depletion resulting in a range of cognitive deficits, including a deterioration in the capacity to learn and a tendency to forget what has been learned. Neurodegenerative diseases resulting in dementia include: Alzheimer, Parkinson, Huntington, Pick, and Creutzfeld Jakob, as well as dementias with multiple etiologies. The population with the highest probability of suffering from one of these diseases are those over 50 years of age, because they have reduced circulating levels of gonadal hormones, one of several risk factors associated with the onset of dementia. Anatomical areas most commonly affected include the hippocampus, the primary motor and somatosensory areas, various limbic structures, and the parieto-temporal, frontal, and entorhinal corticies. Affliction of this last area has been suggested to account for the early olfactory dysfunction often shown by patients after the onset of Alzheimer and Parkinson, leading to the suggestion that olfactory testing could be useful in the early diagnosis of such neurodegenerative diseases.

Terminally ill patients' expectations of nurses.

This exploratory study was undertaken to discover what nursing behaviours terminally ill patients desire. To rank patients' attitudes and judgements a Q-sort consisting of 70 cards was used. The statements covered three categories: physical and psycho-emotional care of patients and psycho-emotional care of significant other/s. "I would like the nurse to help me remain at home for as long as possible" was the most favoured statement and the least favoured was: "I would like the nurse to talk to me about death and dying." The overall theme was that responsive rather than directive nursing behaviours were desired. Analysis identified five Factors from which a model of responsive nursing care was developed. Interpretation of the Factors indicated patients desired responsive nursing care that enabled them and their families to bring their own resources to the dying process, rather than having imposed upon them care which nurses deemed appropriate.

Whole or parts--a theological perspective on 'person'.

The influence of a theological perspective on nursing may be seen in the ethical debates concerning the beginning and end of life, the presence of theologians on ethics committees demonstrating the scope of opinion being sought. The meeting of theology and nursing to be addressed in this paper centres on the interaction of one human being with another, characterized by the terms community, relationship, response. Theology is concerned with persons reaching their potential not in isolation from, but in community with others. Fragmented care ensues from dividing a person into 'manageable' parts. Christian theology knows no such separation and offers a focus for an understanding of 'person' which has relevance for holistic nursing. The same holds true for groups as well as individuals; to focus primarily on self-interest is to ignore the possibilities for mutual exchange. Living 'in relationship' is both the point of departure and the ultimate goal of all created existence. Autonomy and mutuality are two sides of the same coin and the pursuit of one at the expense of the other is, according to Christian theology, not only illusory but a denial of the purpose of creation.
