Aims: This study aimed to establish the screening performance and optimal cut-off points for the Japanese version of Kessler (K)6, K10 and the Depression and Suicide Screen (DSS).Methods: A self-report questionnaire including K6, K10 and DSS, as well as the Center for Epidemiologic Studies -Depression Scale (CES-D), was administered to a random sample of community residents in Japan (non-cases, n = 147) and psychiatric outpatients diagnosed with mood or anxiety disorders according to DSM-IV (cases, n = 17). A receiver-operator characteristics (ROC) curve was drawn to estimate the area under the curve (AUC), the sensitivity, and specificity with the optimal cut-off points for K6, K10, and DSS, which were then compared with those of CES-D. The community sample was also asked to rate each measure on a scale from 'very easy' to 'very hard' to use.Results: K6 and K10 showed a high AUC (0.93-0.94), which was comparable to that of CES-D (0.95), but DSS showed a significantly smaller AUC (0.89) than CES-D (P < 0.05). The optimal cut-off points were estimated as 4/5 for K6, 9/10 for K10, and 1/2 for DSS. The sensitivity of these three scales was similar, but the specificity was lower for DSS than for the other two. K6, K10 and DSS were rated as being 'very easy' or 'easy to use' significantly more than CES-D (P < 0.01).
Conclusion:The screening performance of the Japanese versions of K6 and K10 was comparable with that of CES-D, and better than that of DDS. K6/K10, particularly K6, might have an advantage, even over the CES-D, because of its similar screening performance and better acceptability.
The results of this study revealed significant relationships between plain radiograph and MR images of acute phase OVFs and the incidence of nonunion. As these risk factors are defined more clearly and further validated, they may become essential assessment tools for determining subsequent OVF treatments. Patients with one or more of the earlier-described risk factors for nonunion should be observed carefully and provided with more intensive treatments.
We found that ethyl gallate purified from a dried pod of tara (Caesalpinia spinosa) intensified -lactam susceptibility in methicillin-resistant and methicillin-sensitive strains of Staphylococcus aureus (MRSA and MSSA strains, respectively). This compound and several known alkyl gallates were tested with MRSA and MSSA strains to gain new insights into their structural functions in relation to antimicrobial and -lactam susceptibility-intensifying activities. The maximum activity of alkyl gallates against MRSA and MSSA strains occurred at 1-nonyl and 1-decyl gallate, with an MIC at which 90% of the isolates tested were inhibited of 15.6 g/ml. At concentrations lower than the MIC, alkyl gallates synergistically elevated the susceptibility of MRSA and MSSA strains to -lactam antibiotics. Such a synergistic activity of the alkyl gallates appears to be specific for -lactam antibiotics, because no significant changes were observed in the MICs of other classes of antibiotics examined in this study. The length of the alkyl chain was also associated with the modifying activity of the alkyl gallates, and the optimum length was C5 to C6. The present work clearly demonstrates that the length of the alkyl chain has a key role in the elevation of susceptibility to -lactam antibiotics.
Muscle-preserving selective laminoplasty yielded clinical outcomes equivalent to those of conventional C3-C7 laminoplasty in cervical compression my elopathy. Preservation of the muscles attached at C2 resulted in reduction of postoperative axial pain.
From the water-soluble portion of the methanol extract of coriander (fruit of Coriandrum sativum L.), which has been used as a spice and medicine since antiquity, 33 compounds, including two new monoterpenoids, four new monoterpenoid glycosides, two new monoterpenoid glucoside sulfates and two new aromatic compound glycosides were obtained. Their structures, were clarified by spectral investigation.
Background Although nasal carriage of MRSA has been identified as one of the risk factors for surgical site infection (SSI) with MRSA, there have been no reports of this in the orthopedics field.Methods This prospective observational cohort study included 2,423 consecutive patients who were admitted to our department over 26 months and who underwent orthopedic surgery. We examined the relationship between pre-existing nasal MRSA and subsequent occurrence of SSI with MRSA.Results 63 patients (2.6%) had a positive nasal MRSA culture. 15 patients (0.6%) developed SSI with MRSA. The occurrence of SSI with MRSA in nasal MRSA carriers was significantly higher than that in non-carriers (4 out of 63 (6.3%) vs. 11 out of 2,360 (0.5%); p < 0.001) (adjusted OR: 11; 95% CI: 3–37; p = 0.001).Interpretation We recommend appropriate treatment of patients who are nasal carriers of MRSA before orthopedic surgery.
Eel atrial natriuretic peptide inhibited the serosa-negative transepithelial potential difference and short-circuit current, accompanied by a decrease in NaCl and water absorption across the seawater eel intestine. Similar effects were obtained after treatment with N-terminally truncated eel atrial natriuretic peptide (5-27), indicating that N-terminal amino acids are not essential for the action of eel atrial natriuretic peptide. Although mammalian atrial natriuretic peptides also inhibited the short-circuit current, a 100-fold higher concentration was required to obtain the same effect as with eel atrial natriuretic peptide, indicating that eel atrial natriuretic peptide is 100 times as potent in eel intestine as the mammalian atrial natriuretic peptides. Similarly, in mammalian atrial natriuretic peptide, the four N-terminal amino acids had no significant effects. However, when the C-terminal tyrosine was removed, the potency of rat atrial natriuretic peptide was lowered. Compared with the effects of acetylcholine, serotonin and histamine, eel atrial natriuretic peptide was the most potent inhibitor, with 100% inhibition at 10(-7) M; 50% inhibition was obtained at 10(-2) M in acetylcholine, and 30% inhibition in serotonin (10(-5) M) and histamine (10(-3) M). These inhibitory effects of eel atrial natriuretic peptide were not diminished even in the presence of tetrodotoxin, and were mimicked by 8-bromoguanosine 3',5'-cyclic monophosphate. Based on these results, structure-activity relationships of eel atrial natriuretic peptide and a possible mechanism of action of eel atrial natriuretic peptide are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
