Dreams as portraits of self and group interaction.

Dreams presented in group psychotherapy portray different aspects of the dialectic between the group and the individual. A self psychology perspective emphasizes the interplay between the current self-state of the group-as-a-whole and the selfobject needs of the individual. With this focus in mind, the therapist should help the group to deepen its awareness and capacity to reflect on emerging new abilities ("forward edge") which dream imagery conveys and the needed human responsiveness that can actualize these abilities and thus help the individual and the group to break and transform chains of repetition compulsion. We illustrate this approach with two clinical examples.

Portrait of a species: Chlamydomonas reinhardtii.

Chlamydomonas reinhardtii, the first alga subject to a genome project, has been the object of numerous morphological, physiological, and genetic studies. The organism has two genetically determined mating types (plus and minus) and all stages of the simple life cycle can be evoked in culture. In the nearly 60 years since the first standard laboratory strains were isolated, numerous crosses and exchanges among laboratories have led to some confusion concerning strain genealogy. Here we use analyses of the nuclear internal transcribed spacer regions and other genetic traits to resolve these issues, correctly identify strains currently available, and analyze phylogenetic relationships with all other available similar chlamydomonad types. The presence of a 10-bp indel in ITS2 in some but not all copies of the nuclear ribosomal cistrons of an individual organism, and the changing ratios of these in crosses, provide a tool to investigate mechanisms of concerted evolution. The standard C. reinhardtii strains, plus C. smithii +, plus the new eastern North American C. reinhardtii isolates, comprise one morphological species, one biological species of high sexual intercompatibility, and essentially identical ITS sequences (except the tip of helix I of ITS2). However, variant RFLP patterns characterize strains from each geographic site.

The magnitude of intimate partner violence in Brazil: portraits from 15 capital cities and the Federal District.

This paper concerns the prevalence of intimate partner violence in 15 State capital cities and the Federal District of Brazil. A population-based multi-stage survey in 2002/2003 involved 6,760 15-69-year-old women (respondents). Using the Conflict Tactics Scales--Form R, the overall prevalence of psychological aggression and "minor" and severe physical abuse within couples was 78.3%, 21.5%, and 12.9%, respectively. Prevalence rates varied distinctively between cities. For instance, total physical abuse ranged from 13.2% to 34.8%. On the whole, prevalence was higher in the North and Northeast cities than in the Southeast, South, and Central West. Also, all types of intimate partner violence were more frequent in couples including women who were younger (< 25 years) and had less schooling (< 8 years). After stratifying by gender, although women tended to perpetrate at least one act of physical abuse more often, scores were consistently higher among male partners who were perpetrators. The results are compared to international findings. Regional, demographic, and gender differentials are discussed in light of the growing role of the Brazilian health sector in relation to intimate partner violence.

Primary differentiation in the human blastocyst: comparative molecular portraits of inner cell mass and trophectoderm cells.

The primary differentiation event during mammalian development occurs at the blastocyst stage and leads to the delineation of the inner cell mass (ICM) and the trophectoderm (TE). We provide the first global mRNA expression data from immunosurgically dissected ICM cells, TE cells, and intact human blastocysts. Using a cDNA microarray composed of 15,529 cDNAs from known and novel genes, we identify marker transcripts specific to the ICM (e.g., OCT4/POU5F1, NANOG, HMGB1, and DPPA5) and TE (e.g., CDX2, ATP1B3, SFN, and IPL), in addition to novel ICM- and TE-specific expressed sequence tags. The expression patterns suggest that the emergence of pluripotent ICM and TE cell lineages from the morula is controlled by metabolic and signaling pathways, which include inter alia, WNT, mitogen-activated protein kinase, transforming growth factor-beta, NOTCH, integrin-mediated cell adhesion, phosphatidylinositol 3-kinase, and apoptosis. These data enhance our understanding of the first step in human cellular differentiation and, hence, the derivation of both embryonic stem cells and trophoblastic stem cells from these lineages.

Portrait of human tapeworms.

The tapeworms of the genus Taenia that infect human beings are T. solium, T. saginata and T. saginata asiatica. Taenia solium and T. saginata exhibit unequivocal features that characterize them; in contrast, only recent DNA studies, morphological characteristics, and epidemiological and sanitary aspects indicate that T. saginata asiatica is a subspecies of T. saginata. These 3 tapeworms occur in humans in their adult stage, and the intermediate hosts are pigs for T. solium and T. saginata asiatica and cows for T. saginata. Their identification is crucial considering the migratory increase from Asia to the Western Hemisphere and the fact that these tapeworms coexist in the same environment in Asia; furthermore, it is estimated that movement in both directions across the United States-Mexico border exceeds 200 million persons per yr, and thus, opportunities for acquiring and transporting T. solium infections are multiplied. It is not easy to distinguish among these tapeworms; therefore, a comparative diagram of the 3 parasites is shown in this article, which will facilitate their identification. All morphological features, some of which allow for identification, are clear and can be easily distinguished among the 3 tapeworms.

Adolescent health in the Caribbean: a regional portrait.

OBJECTIVES: This study assessed youth health in the Caribbean Community and Common Market countries and describes the prevalence of health-related factors. METHODS: We used a self-administered classroom questionnaire; questions addressed general health, health care, nutrition, sexual history, drug use, mental health, violence, family characteristics, and relationships with others. RESULTS: Most youths reported good health; however, 1 in 10 reported a limiting disability or significant health problems. Violence was a pervasive concern. Of those who reported history of sexual intercourse, many reported that their first intercourse was forced, and nearly half reported that they were aged 10 years or younger when they first had intercourse. CONCLUSIONS: Although most young people are healthy, problems indicate the importance of monitoring trends and designing effective youth health programs.

Canadian First Nations grandparents raising grandchildren: a portrait in resilience.

Between 1991 and 2001, there was a 20% increase in the number of Canadian children under 18 years old who were living with their grandparents without a parent present in the home. Recent research revealed that Canadians of First Nations origin, including North American Indians, Métis, and Inuit, were vastly over-represented among grandparents raising grandchildren in skipped generation households (households which include only grandparents and grandchildren). Using custom tabulation data from the 1996 Canadian Census, this article presents a profile of First Nations Canadian grandparents raising grandchildren in skipped generation households. Despite extremely high rates of poverty and disability, one-third of First Nations Canadian skipped generation families were raising two or more grandchildren. In comparison to other grandparent caregivers, First Nations custodial caregivers were more likely to also be caring for a senior (23%) and to spend more than 30 hours a week on childcare duties (46%) and on housework (41%). Implications for policy, practice, and research are discussed.

No-bridge of Drosophila melanogaster: portrait of a structural brain mutant of the central complex.

The mutant no-bridge (nobKS49) has its name from a structural defect in the protocerebral bridge of the central complex. This rod-shaped neuropil in nobKS49 has a large gap at the sagittal midplane, with some of the missing material accumulated more laterally. Mutant nob flies have a reduced maximal and average walking speed. Leg coordination is disturbed during turning but not while walking straight. Motivation for walking is low and steps are small due to slow forward swinging of the legs. Flies spontaneously may pass into an autistic (and possibly spastic) state in which they can move their legs and even perform cleaning movements but do not walk or fly. They spontaneously recover if left undisturbed. Gynandromorph experiments place the focus of the walking defects into the head. Mutant flies have a reduced tendency to escape when mechanically stimulated. In a brightly lit arena they do not avoid a black square above the horizon and they are negatively phototactic. In tethered flight optomotor responses are normal but the amplitude of spontaneous torque modulations as well as the number of torque spikes are reduced. If a single black bar is slowly rotated around the fly, the normal response pattern is observed. It vanishes, however, at moderately fast angular velocity at which the wild type still is fully responsible. The behavioral defects support the notion that the protocerebral bridge is part of a higher center for the regulation of behavior.

A portrait of homelessness.

The homeless elderly are vulnerable, silent, and fearful. Their trajectory into homelessness more often than not precludes recovery and takes them on a course toward early death or nursing home placement. Psychiatric nurses who work in community or acute care settings are in key positions to recognize elderly victims of homelessness, assess their needs, match them to services, start them on the road to recovery, and become their advocates. The definition of a homeless person as agreed on in the Report of the Federal Task Force on Homelessness and Severe Mental Illness (1992) is the one used in the Stewart B. McKinney Homeless Assistance Act (Public Law 100-77). A homeless person is someone "who lacks a fixed, regular, and adequate nighttime residence" and whose main nighttime residence is a "supervised public or private shelter designed to provide temporary living accommodations; an institution that provides a temporary residence for individuals intended to be institutionalized; or a public or private place not designed for, or ordinarily used as, a regular sleeping accommodation for human beings." This definition, then, excludes those individuals living on the "fringes" in substandard or condemned housing, a condition that warrants attention in general and particularly among the elderly.

Cutting edge: molecular portrait of human autoimmune disease.

Autoimmune diseases affect 3-5% of the population, are mediated by the immune response to self-Ags, and are characterized by the site of tissue destruction. We compared expression levels of >4,000 genes in PBMC of control individuals before and after immunization to those of individuals with four distinct autoimmune diseases. The gene expression profile of the normal immune response exhibits coordinate changes in expression of genes with related functions over time. In contrast, each individual from all autoimmune diseases displays a similar gene expression profile unrelated to the pattern of the immunized group. To our surprise, genes with a distinct expression pattern in autoimmunity are not necessarily "immune response" genes, but are genes that encode proteins involved in apoptosis, cell cycle progression, cell differentiation, and cell migration.
