Music-instruction intervention for treatment of post-traumatic stress disorder: a randomized pilot study.

BACKGROUND: Post-traumatic Stress Disorder (PTSD) is a common sequelae of severe combat-related emotional trauma that is often associated with significantly reduced quality of life in afflicted veterans. To date, no published study has examined the effect of an active, music-instruction intervention as a complementary strategy to improve the psychological well-being of veterans with PTSD. The purpose of this study was to examine the feasibility and potential effectiveness of an active, music-instruction intervention in improving psychological health and social functioning among Veterans suffering from moderate to severe PTSD. METHODS: The study was designed as a prospective, delayed-entry randomized pilot trial. Regression-adjusted difference in means were used to examine the intervention's effectiveness with respect to PTSD symptomatology (primary outcome) as well as depression, perceptions of cognitive failures, social functioning and isolation, and health-related quality of life (secondary outcomes). RESULTS: Of the 68 Veterans who were self- or provider-referred to the program, 25 (36.7%) were ineligible due to (i) absence of a PTSD diagnosis (n = 3); participation in ongoing intense psychotherapy (n = 4) or inpatient substance abuse program (n = 2); current resident of the Domiciliary (n = 8) and inability to participate due to distance of residence from the VA (n = 8). Only 3 (4.4%) Veterans declined participation due to lack of interest. The mean age of enrolled subjects was 51 years old [range: 22 to 76]. The majority was male (90%). One-quarter were African American or Black. While 30% report working full or part time, 45% were retired due to disability. Slightly over one-quarter were veterans of the OEF/OIF wars. Estimates from regression-adjusted treatment effects indicate that the average PTSD severity score was reduced by 9.7 points (p = 0.01), or 14.3% from pre- to post-intervention. Similarly, adjusted depressive symptoms were reduced by 20.4% (- 6.3 points, p = 0.02). There were no statistically significant regression-adjusted effects on other outcomes, although the direction of change was consistent with improvements. CONCLUSIONS: Our findings suggest that the active, music-instruction program holds promise as a complementary means of ameliorating PTSD and depressive symptoms among this population.

Weekend hospitalisations and post-operative complications following urgent surgery for ulcerative colitis and Crohn's disease.

BACKGROUND: There is increasing complexity in the management of patients with acute severe exacerbation of inflammatory bowel disease [IBD; Crohn's disease (CD), ulcerative colitis (UC)] with frequent requirement for urgent surgery. AIM: To determine whether a weekend effect exists for IBD care in the United States. METHODS: We used data from the Nationwide Inpatient Sample (NIS) 2007, the largest all-payer hospitalisation database in the United States. Discharges with a diagnosis of CD or UC who underwent urgent intestinal surgery within 2 days of hospitalisation were identified using the appropriate ICD-9 codes. The independent effect of admission on a weekend was examined using multivariate logistic regression adjusting for potential confounders. RESULTS: Our study included 7,112 urgent intestinal surgeries in IBD patients, 21% of which occurred following weekend admissions. There was no difference in disease severity between weekend and weekday admissions. Post-operative complications were more common following weekend than weekday hospitalisations in UC [odds ratio (OR) 1.71, 95% confidence interval (CI) 1.01-2.90]. The most common post-operative complication was post-operative infections (Weekend 30% vs. weekday 20%, P = 0.04). The most striking difference between weekend and weekday hospitalisations was noted for needing repeat laparotomy (OR 11.5), mechanical wound complications (OR 10.03) and pulmonary complications (OR 2.22). In contrast, occurrence of any post-operative complication in CD was similar between weekday and weekend admissions. CONCLUSION: Patients with UC hospitalised on a weekend undergoing urgent surgery within 2 days have an increased risk for post-operative complications, in particular mechanical wound complications, need for repeat laparotomy and post-operative infections.

Influence of S. mutans on base-metal dental casting alloy toxicity.

We have highlighted that exposure of base-metal dental casting alloys to the acidogenic bacterium Streptococcus mutans significantly increases cellular toxicity following exposure to immortalized human TR146 oral keratinocytes. With Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), S. mutans-treated nickel-based (Ni-based) and cobalt-chromium-based (Co-Cr-based) dental casting alloys were shown to leach elevated levels of metal ions compared with untreated dental casting alloys. We targeted several biological parameters: cell morphology, viable cell counts, cell metabolic activity, cell toxicity, and inflammatory cytokine expression. S. mutans-treated dental casting alloys disrupted cell morphology, elicited significantly decreased viable cell counts (p < 0.0001) and cell metabolic activity (p < 0.0001), and significantly increased cell toxicity (p < 0.0001) and inflammatory cytokine expression (p < 0.0001). S. mutans-treated Ni-based dental casting alloys induced elevated levels of cellular toxicity compared with S. mutans-treated Co-Cr-based dental casting alloys. While our findings indicated that the exacerbated release of metal ions from S. mutans-treated base-metal dental casting alloys was the likely result of the pH reduction during S. mutans growth, the exact nature of mechanisms leading to accelerated dissolution of alloy-discs is not yet fully understood. Given the predominance of S. mutans oral carriage and the exacerbated cytotoxicity observed in TR146 cells following exposure to S. mutans-treated base-metal dental casting alloys, the implications for the long-term stability of base-metal dental restorations in the oral cavity are a cause for concern.

Base-metal dental casting alloy biocompatibility assessment using a human-derived three-dimensional oral mucosal model.

Nickel-chromium (Ni-Cr) alloys used in fixed prosthodontics have been associated with type IV Ni-induced hypersensitivity. We hypothesised that the full-thickness human-derived oral mucosa model employed for biocompatibility testing of base-metal dental alloys would provide insights into the mechanisms of Ni-induced toxicity. Primary oral keratinocytes and gingival fibroblasts were seeded onto Alloderm™ and maintained until full thickness was achieved prior to Ni-Cr and cobalt-chromium (Co-Cr) alloy disc exposure (2-72 h). Biocompatibility assessment involved histological analyses with cell viability measurements, oxidative stress responses, inflammatory cytokine expression and cellular toxicity analyses. Inductively coupled plasma mass spectrometry analysis determined elemental ion release levels. We detected adverse morphology with significant reductions in cell viability, significant increases in oxidative stress, inflammatory cytokine expression and cellular toxicity for the Ni-Cr alloy-treated oral mucosal models compared with untreated oral mucosal models, and adverse effects were increased for the Ni-Cr alloy that leached the most Ni. Co-Cr demonstrated significantly enhanced biocompatibility compared with Ni-Cr alloy-treated oral mucosal models. The human-derived full-thickness oral mucosal model discriminated between dental alloys and provided insights into the mechanisms of Ni-induced toxicity, highlighting potential clinical relevance.

Hepatitis C/HIV co-infection is associated with higher mortality in hospitalized patients with hepatitis C or HIV.

Up to 10% of all patients with Hepatitis C virus (HCV) infection are co-infected with human immunodeficiency virus (HIV); 25-30% of HIV patients are co-infected with HCV. The aim of this study was to examine the association of HCV/HIV co-infection with outcomes of hospitalized patients compared to those with HCV or HIV monoinfection. Using the 2006 Nationwide Inpatient Sample, patients with HCV or HIV monoinfection or HCV/HIV co-infection were identified using ICD-9-CM codes. We compared liver-related and infection-related admission between the three groups of patients. Multivariate logistic regression was performed to identify independent predictors of in-hospital mortality. A total of 474,843 discharges with HCV monoinfection, 206,758 with HIV monoinfection and 56,304 with HCV/HIV co-infection were included. Liver-related admissions were more common in co-infected patients (15.4%) compared to those with HIV monoinfection (3.3%, P < 0.001). Primary infectious hospitalizations were more common in HIV monoinfection (33.9%) compared to co-infected patients (26%, P < 0.001). HCV/HIV co-infection was associated with higher mortality compared to HCV monoinfection (OR 1.41, 95% CI 1.20-1.65) but not when compared to monoinfected-HIV patients. HCV-associated cirrhosis or complications thereof conferred four times greater mortality risk in patients with HIV (OR 3.96, 95% CI 3.29-4.79). The rate of hospitalization for HCV/HIV co-infected patients (23.5%) was significantly higher than those with HCV (14.8%) or HIV (19.9%) (P < 0.001). HCV/HIV co-infection is associated with significantly higher rates of hospitalization and is a risk factor for in-hospital mortality compared to patients with isolated HCV.

Excess hospitalisation burden associated with Clostridium difficile in patients with inflammatory bowel disease.

BACKGROUND: Clostridium difficile is an important cause of diarrhoea in hospitalised patients. An increasing number of cases of C difficile colitis occur in patients with inflammatory bowel disease (IBD)-Crohn's disease (CD), ulcerative colitis (UC). OBJECTIVE: To estimate the potential excess morbidity and mortality associated with C difficile in hospitalised patients with IBD. METHODS: Data from the Nationwide Inpatient Sample (2003) were analysed and outcomes were examined of patients hospitalised with both C difficile colitis and IBD compared with those hospitalised for either condition alone. The primary outcome was in-hospital mortality. A subgroup analysis was also performed comparing outcomes of C difficile infection in patients with CD and UC. RESULTS: 2804 discharges were diagnosed as having both C difficile and IBD, 44,400 as having C difficile alone, and 77,366 as having IBD alone. On multivariate analysis, patients in the C difficile-IBD group had a four times greater mortality than patients admitted to hospital for IBD alone (aOR = 4.7, 95% CI 2.9 to 7.9) or C difficile alone (aOR = 2.2, 95% CI 1.4 to 3.4), and stayed in the hospital for three days longer (95% CI 2.3 to 3.7 days). Significantly higher mortality, endoscopy and surgery rates were found in patients with UC compared with CD (p<0.05), but no significant difference in length of stay or median hospital charge between the two groups was seen. CONCLUSIONS: C difficile colitis is associated with a significant healthcare burden in hospitalised patients with IBD and carries a higher mortality than in patients with C difficile without underlying IBD.
