‘It's just a peripheral issue’: A qualitative analysis of mental health clinicians’ accounts of (not) addressing sexuality in their work

Sexuality, relationships, and intimacy are integral parts of many peoples’ lives, not negated by mental distress and illness. Yet typically, these needs are not addressed adequately in mental health settings. In‐depth interviews were conducted with mental health clinicians with an aim of exploring their perceptions and understandings of sexuality and sexual concerns within mental health settings. Participants were 22 mental health nurses, psychologists, and psychiatrists working with people across a range of settings in four Australian cities. Sexuality or aspects of this were often not addressed in clinical practice, and this was common across participants’ accounts. A critical thematic analysis was conducted to explore how participants made sense of or explained this silence in relation to sexuality. Two key themes were ‘Sexuality is hard to talk about’ and ‘Sexuality is a “peripheral issue”’. In positioning sexuality as a peripheral issue, participants drew on three key explanations (sub‐themes): that sexuality rarely ‘comes up’, that it is not pragmatic to address sexuality, and that addressing sexuality is not part of participants’ roles or skill sets. A third theme captured the contrasting perception that ‘Sexuality could be better addressed’ in mental health settings. This analysis indicates that, beyond anticipated embarrassment, mental health clinicians from three disciplines account for omissions of sexuality from clinical practice in similar ways. Moreover, these accounts serve to peripheralize sexuality in mental health settings. We consider these results within the context of espoused holistic and recovery‐oriented principles in mental health settings.     

Linking genome and proteome by mass spectrometry: Large-scale identification of yeast proteins from two dimensional gels

The function of many of the uncharacterized open reading frames discovered by genomic sequencing can be determined at the level of expressed gene products, the proteome. However, identifying the cognate gene from minute amounts of protein has been one of the major problems in molecular biology. Using yeast as an example, we demonstrate here that mass spectrometric protein identification is a general solution to this problem given a completely sequenced genome. As a first screen, our strategy uses automated laser desorption ionization mass spectrometry of the peptide mixtures produced by in-gel tryptic digestion of a protein. Up to 90% of proteins are identified by searching sequence data bases by lists of peptide masses obtained with high accuracy. The remaining proteins are identified by partially sequencing several peptides of the unseparated mixture by nanoelectrospray tandem mass spectrometry followed by data base searching with multiple peptide sequence tags. In blind trials, the method led to unambiguous identification in all cases. In the largest individual protein identification project to date, a total of 150 gel spots—many of them at subpicomole amounts—were successfully analyzed, greatly enlarging a yeast two-dimensional gel data base. More than 32 proteins were novel and matched to previously uncharacterized open reading frames in the yeast genome. This study establishes that mass spectrometry provides the required throughput, the certainty of identification, and the general applicability to serve as the method of choice to connect genome and proteome.     

Interaction between human polymorphonuclear leukocytes and Streptococcus milleri group bacteria.

Because Streptococcus milleri group (SMG) bacteria--Streptococcus constellatus, Streptococcus intermedius, and Streptococcus anginosus--exhibit a striking propensity to cause abscesses, the interaction of these organisms with human polymorphonuclear leukocytes (PMNL) was examined. After incubation in pooled normal human serum, SMG stimulated less chemotaxis than did Staphylococcus aureus, in contrast to viridans streptococci, which caused greater chemotaxis than did S. aureus. PMNL ingested greater numbers of SMG and viridans streptococci than S. aureus but killed these organisms more slowly and less completely. Relative resistance to killing by PMNL is expected in organisms that cause abscesses, and inhibition of chemotaxis may contribute to pathogenicity, because delayed arrival of PMNL gives a head start to proliferating bacteria. This study helps explain the capacity of SMG to cause abscesses. It is unclear, however, why viridans streptococci, bacteria that rarely produce abscesses, share some of these same properties.
