RESUMO
BACKGROUND: Various factors may influence job satisfaction for mental healthcare professionals. Identifying these factors can help identify strategies to strengthen job satisfaction. AIMS: To determine the current levels of job satisfaction for mental healthcare workers (MHCWs) in multidisciplinary teams, and to identify factors that impact this experience. METHODS: A sequential mixed methods study was used. Seventy seven MHCWs in regional Australia participated in an online survey. From this sample, 16 participants contributed to discipline-specific focus groups. RESULTS: The majority of participants (83%) were generally satisfied working in a mental healthcare role. A higher proportion reported a decrease in satisfaction in the past year than an increase. Differences between the four disciplines of MHCWs studied were evident. Commonalities were seen in professional recognition and direct client work. CONCLUSIONS: Factors in the service delivery environment are having a negative impact in job satisfaction of MHCWs. Team dynamics and team leader qualities are important factors that support them in their work. Results from this study may be used to inform leadership education in mental health services. Individual discipline perspective can inform retention and recruitment strategies.

Phosphorus can be removed from wastewater biologically, chemically, or through a combination of the two. In this study, we applied environmental life-cycle assessment to develop a metric with which decision-makers can compare processes. Two phosphorus-removal scenarios were contrasted-one based on a desktop-level design and one based on full-scale operational data. To achieve 0.5 mg/L effluent phosphorus (desktop design), a biological-only process would incur 5.2% less effect on global warming potential, as contrasted with a chemical-only process. At an effluent quality of 0.1 mg/L (full-scale facilities), where a biological process augmented with chemicals was contrasted with a chemical-only process, the relative gap increases to 13.2%. As chemical usage increased, the adverse environmental effect of chemical treatment only increased. The results of this study suggest that best practices would center phosphorus removal first on the biological process, with chemical processes added only as necessary.

The purpose of this research was to develop a better understanding of the dynamic effects of anaerobic hydraulic retention time (HRT) on both enhanced biological phosphorus removal (EBPR) performance and enrichment of phosphorus accumulating organisms (PAOs). The research was conducted using laboratory-scale sequencing batch reactors inoculated with mixed microbial consortia and fed real wastewater. Exposing microorganisms to extended anaerobic HRTs is not recommended for EBPR configured systems. In this research, however, longer anaerobic exposure did not negatively affect performance even if volatile fatty acids were depleted. Further, extended anaerobic HRTs may positively affect phosphorus removal through enhanced aerobic uptake. The EBPR consortia also appear to maintain reserve energetic capacity in the form of polyphosphate that can be used to survive and grow under variable operational and environmental conditions. Finally, the tested EBPR systems yield mixed microbial consortia enriched with PAOs (specifically Candidatus Accumulibacter phosphatis) at approximately 7.1 to 21.6% of the total population.

BACKGROUND: Three patients received solid organ transplants from a common donor and were subsequently discharged from the hospital following an uneventful hospital course. Within 30 days, all 3 organ recipients returned to the hospital with varying symptoms that progressed to rapid neurological deterioration, coma, and death. OBJECTIVE: To describe the clinical, neuroradiological, and pathological findings of rabies virus infection in organ transplant recipients infected from a common donor. DESIGN: Case series involving a common donor and 3 organ recipients ascertained through review of clinical course and autopsy findings. A fourth case was determined by review of pending autopsy cases in which death occurred within the same time interval. Portions of postmortem central nervous system and organ tissues were frozen and formalin-fixed. Fluids and tissues were also collected for cultures, serology, and molecular studies. Postmortem fluids and tissues and antemortem fluids and tissues from all 4 transplant recipients and serum and banked lymphocyte or spleen cells from the donors were sent to the Centers for Disease Control and Prevention for further evaluation. SETTING: Transplant unit of an urban teaching hospital. RESULTS: Antemortem cerebrospinal fluid analysis for 3 of the 4 recipients was consistent with a viral etiology. Neuroimaging and electroencephalogram studies were suggestive of an infectious encephalitis or a toxic encephalopathy. Initial laboratory testing did not demonstrate an infectious etiology. Postmortem histologic analysis, immunohistochemistry, electron microscopy, and direct fluorescence antibody testing revealed rabies virus infection. Serological testing done postmortem confirmed rabies virus infection in the common donor. CONCLUSIONS: These cases demonstrate a risk for transmitting rabies virus infection through solid organ and tissue transplantation, and this diagnosis should be considered in any rapidly progressing neurological disease.

BACKGROUND: Recurrent disease after liver transplant is a significant problem. Recurrent primary biliary cirrhosis (RPBC) is a histologic diagnosis. Clinical data is unreliable in predicting or diagnosing recurrence. RPBC appears to have a changing clinical presentation in recent years. MATERIALS AND METHODS: The diagnosis of RPBC after liver transplantation was made histologically. Data were obtained from our prospectively maintained liver-transplant database and evaluated statistically. RESULTS: Between 1985 and 1999, 1,835 liver transplants were performed, 169 for PBC. One hundred fifty-six patients were evaluated (one patient received retransplantation, and 13 were excluded). Seventeen (10.9%) experienced recurrence. Median posttransplantation follow-up time was 72.1 months. Median time to recurrence was 49.6 months. Median follow-up time after recurrence was 11.5 months. Neither acute rejection episodes (P=0.34) nor OKT3 use (P=0.36) before diagnosis of recurrence was significant. The combination of cyclosporine, azathioprine, and prednisolone demonstrated recurrence in 6 of 71 (8.4%). Six of 49 (12.2%) patients treated with cyclosporine with or without mycophenolate mofetil and prednisolone experienced recurrence. Six of 36 (16.7%) patients treated with tacrolimus and prednisolone with or without mycophenolate mofetil experienced recurrence. Patients treated with cyclosporine had numerically fewer recurrences than those treated with tacrolimus (P=0.11). CONCLUSIONS: Patients with RPBC demonstrated prolonged survival. Clinical factors did not aid in predicting RPBC. The clinical course of RPBC appears to be different than in the earlier years of liver transplantation. Immunosuppression may play a role. The use and type of antimetabolite drugs had no affect on recurrence. RPBC demonstrated a different clinical course with tacrolimus treatment (shorter time to recurrence) and increased incidence when compared with cyclosporine treatment. Controlled randomized studies are necessary to determine differences between tacrolimus and cyclosporine treatment, if any.

BACKGROUND: This prospective analysis evaluated the effect of tumor KRAS status on efficacy of second-line panitumumab plus folinic acid/5-fluorouracil/irinotecan (FOLFIRI). METHODS: This phase 2, open-label, single-arm study enrolled patients with unresectable, measurable metastatic colorectal cancer (mCRC) after failure of first-line treatment with oxaliplatin-based chemotherapy plus bevacizumab. Patients received panitumumab 6 mg/kg plus FOLFIRI every 2 weeks until disease progression or intolerability. Tumor assessments per Response Evaluation Criteria in Solid Tumors (RECIST) were performed by the investigators every 8 weeks from weeks 8-32 and every 12 weeks thereafter. KRAS status was determined by real-time polymerase chain reaction (PCR) on DNA extracted from fixed tumor sections. Efficacy endpoints included objective response rate, progression-free survival (PFS), and overall survival (OS). Safety endpoints included incidence of adverse events (AEs). Endpoints were evaluated by tumor KRAS status. RESULTS: Of 116 patients enrolled, 109 patients with known tumor KRAS status received treatment; 59% had wild-type KRAS, and 41% had mutant KRAS. Fifteen patients (23%) with wild-type KRAS and 7 patients (16%) with mutant KRAS had a complete or partial response to treatment. Median PFS was 26 weeks (95% CI, 19-33 weeks) and 19 weeks (95% CI, 12-25 weeks) in the wild-type KRAS and mutant KRAS strata, respectively. Median OS was 50 weeks (95% CI, 39-76 weeks) and 31 weeks (95% CI, 23-47 weeks) in wild-type KRAS and mutant KRAS strata, respectively. Skin-related toxicities (86% of all patients) and diarrhea (74%) were the most common AEs. CONCLUSION: Panitumumab plus FOLFIRI numerically improved objective response rate, PFS, and OS in favor of patients with wild-type KRAS tumors. The safety profile was consistent with panitumumab plus FOLFIRI trials in similar patient populations.

Graft-versus-host disease (GVHD) after liver transplantation is rare but associated with a very high mortality (over 85%). Most treatments focus on increasing immunosuppression, addition of antibody preparations such as OKT3 and antithymocyte globulin to eliminate the donor lymphocytes, and supporting myelopoiesis by use of cytokines. However, the results are very poor. We reasoned that a better therapeutic approach would be to reduce the immunosuppression and allow the patient's immune system an opportunity to reject the allograft donor T cells. We tested this novel therapeutic approach in 3 patients diagnosed with GVHD. Two patients had rapid loss of donor T cell chimerism and resolution of their symptoms. The other patient continued to progress to severe GVHD and died. The patients who responded to withdrawal of immunosuppression had a later onset of symptoms and a lower level of donor CD3+ T cells at the start of treatment. We conclude that larger studies are needed to further evaluate these results and to determine what factors may affect the likelihood that a patient may respond to this approach.

CONTEXT: Establishing adequate interobserver agreement is crucial not only for standardization of patient care but also to ensure validity of findings in multi-institutional trials. OBJECTIVE: To evaluate interobserver agreement in assessing chronic hepatitis C (HCV) and acute cellular rejection (ACR) among 17 hepatopathologists involved in the "Hepatitis C 3" trial. DESIGN: The trial is a randomized multicenter (17 institutions) study involving 312 patients undergoing transplantation for HCV. Patients are randomized to 3 treatment arms. For final data analysis, all biopsy specimens are reviewed by a central pathologist (G.J.N.). Recurrence of HCV is evaluated according to the Batts and Ludwig schema. The 1997 Banff schema is used to evaluate ACR. To assess interobserver agreement, hematoxylin-eosin-stained sections from 11 liver biopsy specimens (6 HCV and 5 ACR) were sent by the central pathologist to 16 local pathologists from 13 institutions. Statistical analysis was performed on raw ACR/HCV data as well as data grouped according to clinically significant primary endpoint cutoffs. RESULTS: Statistically significant agreement was found among all participating pathologists (P < .001). On kappa analysis, the degree of agreement was rated "moderate" for HCV grade and stage and ACR global grading (kappa = 0.30, 0.33, and 0.37, respectively). Interobserver agreement was weaker for rejection activity index scoring of ACR (kappa = 0.15). A stronger degree of agreement was found when scores were grouped based on endpoint cutoffs (kappa = 0.76 "almost perfect" for HCV and 0.62 "substantial" for ACR). CONCLUSIONS: An overall statistically significant interobserver agreement was found among 17 pathologists using the 1997 Banff schema and the Batts and Ludwig schema.
