African-American Cancer Survivors' Use of Religious Beliefs to Positively Influence the Utilization of Cancer Care.

Among African-Americans, religion impacts health-seeking behaviors. This qualitative study used criterion purposeful sampling and thematic analysis in analysis of data from 31 African-American cancer patients to understand the influence of religion on the utilization of cancer care services. Our findings suggest that religious beliefs and practices positively influenced attitudes toward their illness and ability to endure treatment. God's ability to heal and cure, God's control over survival, God's will over their lives, and God's promise for health and prosperity were examples of survivor's religious beliefs. Religious practices such as prayer promoted a trusting relationship with healthcare providers and were a source of strength and encouragement.

Strategies African-American Cancer Survivors Use to Overcome Fears and Fatalistic Attitudes.

This qualitative study explored strategies African-American cancer survivors use to overcome their fears and fatalistic attitudes toward cancer at the point of diagnosis through completion of treatment. Thirty-one African-American cancer survivors who had completed or nearly completed treatment were recruited through criterion purposeful sampling. In-depth, open-ended interviews were used to collect data. The data were analyzed using thematic analysis. Of the 31 survivors interviewed, 26 reported being fearful of cancer and believed that cancer would result in death. These cancer survivors were particularly fearful of having a cancer had spread, of being isolated, and performing less effectively at work. Strategies used to overcome these fears included increasing their own awareness about cancer, using positive self-talk, and avoiding negative people. The findings suggest that past experiences continue to influence fears and fatalistic perspectives about cancer and that educational resources to inform the public about cancer may be ignored until there is a confirmed diagnosis of cancer. Televised news broadcasts of high-profile personalities who had died from cancer were also anxiety provoking, particularly if the cancer survivor died of a recurrence from cancer. Prevalent sources of information and support for these survivors were family members or close friends they trusted with personal information, perceived as strong, or experienced in the care of other cancer survivors.

Molecular evidence of N-methyl-D-aspartate receptor hypofunction in schizophrenia.

Blockade of N-methyl-D-aspartate receptors (NMDARs) produces behavior in healthy people that is similar to the psychotic symptoms and cognitive deficits of schizophrenia and can exacerbate symptoms in people with schizophrenia. However, an endogenous brain disruption of NMDARs has not been clearly established in schizophrenia. We measured mRNA transcripts for five NMDAR subunit mRNAs and protein for the NR1 subunit in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia and control (n=74) brains. Five NMDAR single-nucleotide polymorphisms (SNPs) previously associated with schizophrenia were tested for association with NMDAR mRNAs in postmortem brain and for association with cognitive ability in an antemortem cohort of 101 healthy controls and 48 people with schizophrenia. The NR1 subunit (mRNA and protein) and NR2C mRNA were decreased in postmortem brain from people with schizophrenia (P=0.004, P=0.01 and P=0.01, respectively). In the antemortem cohort, the minor allele of NR2B rs1805502 (T5988C) was associated with significantly lower reasoning ability in schizophrenia. In the postmortem brain, the NR2B rs1805502 (T5988C) C allele was associated with reduced expression of NR1 mRNA and protein in schizophrenia. Reduction in NR1 and NR2C in the DLPFC of people with schizophrenia may lead to altered NMDAR stoichiometry and provides compelling evidence for an endogenous NMDAR deficit in schizophrenia. Genetic variation in the NR2B gene predicts reduced levels of the obligatory NR1 subunit, suggesting a novel mechanism by which the NR2B SNP may negatively influence other NMDAR subunit expression and reasoning ability in schizophrenia.

Connective-tissue disease following breast augmentation: a preliminary test of the human adjuvant disease hypothesis.

It has been proposed that scleroderma in particular or connective-tissue diseases in general may be caused by exposure to silicone-containing materials used for breast augmentation. We performed a historical cohort study to estimate the point prevalence of this potential complication sometimes referred to as "human adjuvant disease." Three-hundred and seventy-eight patients who underwent augmentation mammaplasty with silicone-containing envelope-type prostheses from 1970 through 1981 were surveyed. Regional musculoskeletal syndromes, fibrositis, or osteoarthritis occurred in a third (38 of 125) of our responders. No patient developed an inflammatory systemic rheumatic disease during the period of observation (mean 6.8 years for the 125 subjects). Using calculations based on risk for development of rheumatic disease, it does not appear likely that augmentation mammaplasty is a significant or major inducer of inflammatory connective-tissue diseases in general. However, the number of patients surveyed was small, and our results must be considered preliminary. We could not exclude a specific risk for the development of scleroderma.
