Efficacy of bifocal diagnosis-independent group psychoeducation in severe psychiatric disorders: results from a randomized controlled trial

Despite evidence for its efficacy, diagnosis-specific psychoeducation is not routinely applied. This exploratory randomized controlled trial analyses the efficacy of an easily implementable bifocal diagnosis-mixed group psychoeducation in the treatment of severe psychiatric disorders regarding readmission, compliance and clinical variables, for example global functioning. Inpatients of the Psychiatric Hospital of the University of Basel (N=82) were randomly assigned to a diagnosis-mixed psychoeducational (PE) or a non-specific intervention control group. Relatives were invited to join corresponding family groups. Results at baseline, 3- and 12-month follow-ups are presented. Better compliance after 3months and a lower suicide rate were significant in favour of PE. For most other outcome variables, no significant differences, however advantages, in PE were found. In summary, it can be concluded that diagnosis-mixed group psychoeducation is effective in the treatment of severe psychiatric disorders. The effects can be classified as induced by distinctive psychoeducational elements. Findings similar to those on psychosis-specific programmes justify clinical application and further investigatio

Giant extra-hepatic thrombosed portal vein aneurysm: a case report and review of the literature.

BACKGROUND: Extrahepatic Portal vein aneurysm (EPVA) is a rare finding that may be associated with different complications, e.g. thrombosis, rupture, portal hypertension and compression of adjacent structures. It is being diagnosed more frequently with the advent of modern cross-sectional imaging. Our review of the English literature disclosed 13 cases of thrombosed EPVA. CASE PRESENTATION: A 50-years-old woman presented with acute abdominal pain but no other symptom. She had no relevant medical history. Palpation of the right upper quadrant showed tenderness. Laboratory tests were unremarkable. A computed tomography showed portal vein aneurysm measuring 88 × 65 mm with thrombosis extending to the superior mesenteric and splenic vein. The patient was treated conservatively with anticoagulation therapy. She was released after two weeks and followed on an outpatient basis. At two months, she reported decreased abdominal pain and her physical examination was normal. A computed tomography was performed showing a decreased thrombosis size and extent, measuring 80 × 55 mm. CONCLUSIONS: Although rare, surgeons should be made aware of this entity. Complications are various. Conservative therapy should be chosen in first intent in most cases. We reported the case of the second largest thrombosed extra-hepatic PVA described in the literature, treated by anticoagulation therapy with a good clinical and radiological response

Drain Versus No Drain in Open Mesh Repair for Incisional Hernia, Results of a Prospective Randomized Controlled Trial.

Open mesh repair of incisional hernia is associated with different local complications, particularly bleeding and seroma formation. Traditionally, drains have been placed perioperatively to prevent these complications, despite the lack of scientific evidence or expert consensus. We formulated the hypothesis that the absence of drainage would reduce number of patients presenting collections or complications. The present study aimed to compare postoperative complication rates after open mesh repair for incisional hernia with or without prophylactic wound drainage. Prospective randomized study using standardized surgical technique and drain placement. The primary endpoint was the evaluation of residual fluid collection with ultrasound on postoperative day 30. Other complications, subdivided into medical and surgical, were analyzed as secondary endpoints. There were 144 patients randomized (70 with drain, 74 without drain). No difference was identified between both groups for fluid collection at 30 days (60.3% vs. 62%, p = 0.844). However, less surgical complications were identified in the drain group (21.7% vs. 42.7%, p = 0.007), with a lower wound dehiscence rate (1.5% vs. 9.3%, p = 0.041). Prophylactic drainage in open incisional hernia repair does not objectively reduce the rate of postoperative fluid collections. Therefore, our results do not support the use of routine drainage in incisional hernia repair. Trial registration on clinicaltrials.gov (NCT00478348)

18F- FDG PET/CT-derived parameters predict clinical stage and prognosis of esophageal cancer.

Although <sup>18</sup> F- FDG PET/CT is validated in baseline workup of esophageal cancer to detect distant metastases, it remains underused in assessing local staging and biology of the primary tumor. This study aimed to evaluate the association between <sup>18</sup> F- FDG PET/CT-derived parameters of esophageal cancer, and its clinico-pathological features and prognosis. All patients (n = 86) with esophageal adenocarcinoma or squamous cell cancer operated between 2005 and 2014 were analyzed. Linear regression was used to identify clinico-pathologic features of esophageal cancer associated with the tumor's maximal Standardized Uptake Value (SUV <sub>max</sub> ), Total Lesion Glycolysis (TLG) and Metabolic Tumor Volume (MTV). ROC curve analysis was performed to precise the optimal cutoff of each variable associated with a locally advanced (cT3/4) status, long-term survival and recurrence. Kaplan Meier curves and Cox regression were used for survival analyses. High baseline SUV <sub>max</sub> was associated with cT3/4 status and middle-third tumor location, TLG with a cT3/4 and cN+ status, whereas MTV only with active smoking. A cT3/4 status was significantly predicted by a SUV <sub>max</sub> > 8.25 g/mL (p < 0.001), TLG > 41.7 (p < 0.001) and MTV > 10.70 cm <sup>3</sup> (p < 0.01) whereas a SUV <sub>max</sub> > 12.7 g/mL was associated with an early tumor recurrence and a poor disease-free survival (median 13 versus 56 months, p = 0.030), particularly in squamous cell cancer. Baseline <sup>18</sup> F- FDG PET/CT has a high predictive value of preoperative cT stage, as its parameters SUV <sub>max</sub> , TLG and MTV can predict a locally advanced tumor with high accuracy. A SUV <sub>max</sub> > 12.7 g/mL may herald early tumor recurrence and poor disease-free survival

Robotic-Assisted Surgery Improves the Quality of Total Mesorectal Excision for Rectal Cancer Compared to Laparoscopy: Results of a Case-Controlled Analysis.

BACKGROUND: The use of a robotic surgical system is claimed to allow precise traction and counter-traction, especially in a narrow pelvis. Whether this translates to improvement of the quality of the resected specimen is not yet clear. The aim of the study was to compare the quality of the TME and the short-term oncological outcome between robotic and laparoscopic rectal cancer resections. METHODS: 20 consecutive robotic TME performed in a single institution for rectal cancer (Rob group) were matched 1:2 to 40 laparoscopic resections (Lap group) for gender, body mass index (BMI), and distance from anal verge on rigid proctoscopy. The quality of TME was assessed by 2 blinded and independent pathologists and reported according to international standardized guidelines. RESULTS: Both samples were well matched for gender, BMI (median 25.9 vs. 24.2 kg/m(2), p = 0.24), and level of the tumor (4.1 vs. 4.8 cm, p = 0.20). The quality of the TME was better in the Robotic group (complete TME: 95 vs. 55 %; p = 0.0003, nearly complete TME 5 vs. 37 %; p = 0.04, incomplete TME 0 vs. 8 %, p = 0.09). A trend for lower positive circumferential margin was observed in the Robotic group (10 vs. 25 %, p = 0.1). CONCLUSIONS: These results suggest that robotic-assisted surgery improves the quality of TME for rectal cancer. Whether this translates to better oncological outcome needs to be further investigated

Novel Medication Supply Model Guarantees Adequate Management and High Adherence to Polypharmacy in Older Opioid Users – Preliminary Results with Outpatients

Background: Life expectancy of older drug users has increased, primarily thanks to opioid agonist treatment (OAT). Nursing homes are often not adapted to accommodate patients with substance use disorders. Although care and adherence to polypharmacy in older opioid users need considerable resources e.g., daily visits to an outpatient clinic, outpatient treatment and surveillance are provided as long as possible. We developed a novel medication supply model with an electronic dispenser of pre-packed medications located at patient home, after allowing for law requirements concerning the dispensing of opioids, and present preliminary results from three illustrative outpatients. Methods: The community pharmacy provided unit-of-dose pouches with all solid oral medications directly to patient home. Opioids for substitution were obtained at the addiction clinic in at least weekly intervals, otherwise in the pouches. The pouches were loaded into a lockable, remote-controlled medication management aid that was programmed according to the patient’s medication schedule. The dispenser reminds patients with acoustic alerts to take their medication and records dates and times of medication retrievals. It automatically sends an alert if a patient misses to retrieve a dose. Results: Our three outpatients used the electronic dispenser during 659, 118 and 61 days, with a total of 5, 9, and 18 pills to take daily at 1, 3 and 5 intake times, respectively. The majority of the doses were taken on the preset time (94%, 68.2% and 73.7%) or deliberately in advance (pocket dose). Clinical benefits were initiation and maintenance of a therapy for dementia over 18 months and suppression of HIV viral load over 1.8 years (patient 1), prevention of further dose escalation of pain medication (patient 2) and release of prompts to initiate the existential task of cooking (patient 3). Conclusion: Our novel supply model allows adequate implementation and persistence of complex treatments with outpatients. Clinical outcomes improved, patients and caregivers were satisfied, and resources were saved

QTc interval and resting heart rate as long-term predictors of mortality in type 1 and type 2 diabetes mellitus: a 23-year follow-up

Aims/hypothesis: We evaluated the association of QT interval corrected for heart rate (QTc) and resting heart rate (rHR) with mortality (all-causes, cardiovascular, cardiac, and ischaemic heart disease) in subjects with type 1 and type 2 diabetes. Methods: We followed 523 diabetic patients (221 with type 1 diabetes, 302 with type 2 diabetes) who were recruited between 1974 and 1977 in Switzerland for the WHO Multinational Study of Vascular Disease in Diabetes. Duration of follow-up was 22.6 ± 0.6years. Causes of death were obtained from death certificates, hospital records, post-mortem reports, and additional information given by treating physicians. Results: In subjects with type 1 diabetes QTc, but not rHR, was associated with an increased risk of: (1) all-cause mortality (hazard ratio [HR] 1.10 per 10ms increase in QTc, 95% CI 1.02-1.20, p = 0.011); (2) mortality due to cardiovascular (HR 1.15, 1.02-1.31, p = 0.024); and (3) mortality due to cardiac disease (HR 1.19, 1.03-1.36, p = 0.016). Findings for subjects with type 2 diabetes were different: rHR, but not QTc was associated with mortality due to: (1) all causes (HR 1.31 per 10 beats per min, 95% CI 1.15-1.50, p < 0.001); (2) cardiovascular disease (HR 1.43, 1.18-1.73, p < 0.001); (3) cardiac disease (HR 1.45, 1.19-1.76, p < 0.001); and (4) ischaemic heart disease (HR 1.52, 1.21-1.90, p < 0.001). Effect modification of QTc by type 1 and rHR by type 2 diabetes was statistically significant (p < 0.05 for all terms of interaction). Conclusions/interpretation: QTc is associated with long-term mortality in subjects with type 1 diabetes, whereas rHR is related to increased mortality risk in subjects with type 2 diabete

Role of the Occluded Conformation in Bacterial Dihydrofolate Reductases

Dihydrofolate reductase (DHFR) from Escherichia coli (EcDHFR) adopts two major conformations, closed and occluded, and movement between these two conformations is important for progression through the catalytic cycle. DHFR from the cold-adapted organism Moritella profunda (MpDHFR) on the other hand is unable to form the two hydrogen bonds that stabilize the occluded conformation in EcDHFR and so remains in a closed conformation during catalysis. EcDHFR-S148P and MpDHFR-P150S were examined to explore the influence of the occluded conformation on catalysis by DHFR. Destabilization of the occluded conformation did not affect hydride transfer but altered the affinity for the oxidized form of nicotinamide adenine dinucleotide phosphate (NADP+) and changed the rate-determining step of the catalytic cycle for EcDHFR-S148P. Even in the absence of an occluded conformation, MpDHFR follows a kinetic pathway similar to that of EcDHFR with product release being the rate-limiting step in the steady state at pH 7, suggesting that MpDHFR uses a different strategy to modify its affinity for NADP+. DHFRs from many organisms lack a hydrogen bond donor in the appropriate position and hence most likely do not form an occluded conformation. The link between conformational cycling between closed and occluded forms and progression through the catalytic cycle is specific to EcDHFR and not a general characteristic of prokaryotic DHFR catalysis

Implementation of Enhanced Recovery (ERAS) in Colorectal Surgery Has a Positive Impact on Non-ERAS Liver Surgery Patients.

BACKGROUND: Enhanced recovery after surgery (ERAS) reduces complications and hospital stay in colorectal surgery. Thereafter, ERAS principles were extended to liver surgery. Previous implementation of an ERAS program in colorectal surgery may influence patients undergoing liver surgery in a non-ERAS setting, on the same ward. This study aimed to test this hypothesis. METHODS: Retrospective analysis based on prospective data of the adherence to the institutional ERAS-liver protocol (compliance) in three cohorts of consecutive patients undergoing elective liver surgery, between June 2010 and July 2014: before any ERAS implementation (pre-ERAS n = 50), after implementation of ERAS in colorectal (intermediate n = 50), and after implementation of ERAS in liver surgery (ERAS-liver n = 74). Outcomes were functional recovery, postoperative complications, hospital stay, and readmissions. RESULTS: The three groups were comparable for demographics; laparoscopy was more frequent in ERAS-liver (p = 0.009). Compliance with the enhanced recovery protocol increased along the three periods (pre-ERAS, intermediate, and ERAS-liver), regardless of the perioperative phase (pre-, intra-, or postoperative). ERAS-liver group displayed the highest overall compliance rate with 73.8 %, compared to 39.9 and 57.4 % for pre-ERAS and intermediate groups (p = 0.072/0.056). Overall complications were unchanged (p = 0.185), whereas intermediate and ERAS-liver groups showed decreased major complications (p = 0.034). Consistently, hospital stay was reduced by 2 days (p = 0.005) without increased readmissions (p = 0.158). CONCLUSIONS: The previous implementation of an ERAS protocol in colorectal surgery may induce a positive impact on patients undergoing non-ERAS-liver surgery on the same ward. These results suggest that ERAS is safely applicable in liver surgery and associated with benefits
