Diagnostic performance of labial minor salivary gland flow measurement for assessment of xerostomia

ObjectiveMinor salivary gland flow rate (MF) has been proposed as a key feature of xerostomia (subjective feeling of dry mouth). To assess its diagnostic performance, MF was compared in xerostomia and control subjects.DesignSixty-six subjects with xerostomia and 30 controls were enrolled. MF was measured in the lower labial mucosa using the iodine–starch filter paper method. Stimulated whole salivary flow rates were also measured using the gum test (stimulated-WF).ResultsBoth labial-MF and stimulated-WF were significantly lower in xerostomia subjects than in controls. There was a positive correlation between labial-MF and stimulated-WF in control but not xerostomia subjects. In xerostomia subjects compared to controls, there was a significantly larger reduction in labial-MF than in stimulated-WF. Xerostomia was most accurately diagnosed using a labial-MF cutoff value of 0.25 μL/cm²/min. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy at this cutoff value were 1.00, 0.87, 0.93, 1.00, and 0.96, respectively. Compared to respective values of 0.64, 1.00, 1.00, 0.56, and 0.75 for stimulated-WF at the traditional cutoff of 1.0 mL/min, these data indicate the higher sensitivity, negative predictive value, and diagnostic accuracy of labial-MF.ConclusionsXerostomia was more strongly related to reduction of labial-MF than to that of stimulated-WF. Xerostomia was most likely triggered at a labial-MF cut-off value of 0.25 μL/cm²/min based on results from the iodine–starch method.     

Bulgaria mental health country profile

The mental health profile of Bulgaria has been compiled and following analysis of both the factual findings and the process of data collection a report has been prepared. The subject of discussion in the paper concerns several major findings: the discrepancy between what the policy documents state and the actual situation in mental health; the organizational culture, which alienates; and the peculiarities of the process of change and how it is driven under political pressure from outside the country. Analysis extends to encompass the influence of the general health reform on the mental health sector, the deficits of the leadership and how they impact on the effectiveness of the system, and the interdependence between the country's economy and the health sector. A conclusion is made about the need to consolidate the public health approach using the lever of international collaboration in the field of mental health.     

Cloning and characterization of a TNF-like protein of Plecoglossus altivelis (ayu fish)

Ayu TNF cDNA contains an open reading frame of 708bp encoding 235 amino acids. Poly adeniration (A) signal and eight AU-rich sequences were present in 858bp 3' UTR. Southern blot analysis indicated that ayu TNF is single-copy gene. The genomic DNA sequence of ayu TNF, consisting of four exons and three introns, was shown to be conserved well throughout evolution from fish to mammals. The amino acid sequence of ayu TNF was shown to have 32-41% of amino acid identity to other known fish TNF, and about 30% of amino acid identity to mammalian TNFs. A phylogenetic analysis based on the amino acid sequence of TNF indicated that ayu has a distinctive evolutionary path. Also, two residues of cysteine important for the formation of the three-dimensional structure were conserved in ayu TNF. For the functional analysis, ayu TNF was inserted into expression vector pCold/TF, transferred into Chaperone Competent Cells BL21 (pKJE7); this produced soluble mature ayu recombinant TNF. Ayu recombinant TNF was shown to induce respiratory burst activity from ayu kidney. The above results indicate that ayu TNF plays an important role in phylaxis, as it does in mammals.     

Practices and Processes Used in the Return to Work of Injured New South Wales nurses: Are These Consistent With RTW Best Practice Principles?

Purpose Workplace injury and illness rates are high within the nursing profession, and in conjunction with current nursing shortages, low retention rates, and the high cost of workplace injury, the need for effective return to work (RTW) for injured nurses is highlighted. This study aimed to identify current practices and processes used in the RTW of injured nurses, and determine if these are consistent with the seven principles for successful RTW as described by the Canadian Institute for Work & Health. Method As part of a larger cross-sectional study, survey data were collected from New South Wales nurses who had sustained a major workplace injury or illness. Survey questions were coded and matched to the seven principles for successful RTW. Results Of the 484 surveys eligible for analysis, most were from Registered Nurses (52%) in the Public Hospital Sector (48%). Responses indicated four main areas of concern: a commitment to health and safety by the workplace; early and considerate employer contact; provision of modified work; and individual knowledge of and involvement in the RTW process. Positive participant responses to co-worker and supervisor involvement were identified as areas consistent with best practice principles. Conclusions These findings suggest the practices and processes involved in the RTW of injured nurses are inconsistent with best practice principles for RTW, highlighting the need for interventions such as targeted employer education and training for improved industry RTW outcomes.
