- AIM: The aims of this study were i) to assess a new and more detailed histopathological classification and to analyze concordance between pathologists in the histopathological classification of pseudomyxoma peritonei (PMP); ii) to analyze the expression in the stroma of the particularly interesting new cysteine-histidine (PINCH) protein and its prognostic importance in PMP.MATERIALS AND METHODS: Surgical specimens from 81 patients, classified according to the Ronnett et al histopathological classification were compared to a new system with four groups ranging from indolent to aggressive growth patterns. PINCH protein expression was analyzed and was related to clinical variables.RESULTS: The new four-group classification provided better prognostic information than the classification according to Ronnett et al. (p=0.04). Expression of the PINCH protein in the stroma was found in 83% of the cases and was associated with high tumor burden (p=0.002) and a poor prognosis (p=0.04).CONCLUSION: The proposed new PMP classification system may provide additional prognostic information. PINCH protein is expressed in PMP and has prognostic information.

- BACKGROUND:The aim of this study was to compare debulking surgery and cytoreductive surgery (CRS) in patients with Pseudomyxoma peritonei (PMP) regarding efficacy and safety.PATIENTS AND METHODS:Data were extracted from medical records and treatment outcomes were analyzed for all 152 patients with PMP who were scheduled for debulking surgery and intraperitoneal chemotherapy (IPC) or CRS and IPC at Uppsala University Hospital, Uppsala, Sweden, between September 1993 and December 2008.RESULTS:One hundred and ten patients (73%) were treated with CRS and IPC and 40 (27%) with debulking surgery and IPC. In two patients (1%), surgery was defined as open and close. Patients with CRS and IPC had a 74% 5-year overall survival (OS) rate compared with 40% for those treated with debulking surgery (P < 0.001). Patients with no residual macroscopic tumour (R1 resection) had a better 5-year OS rate of 94% compared with 28% for patients with macroscopic residual tumour (R2) (P < 0.001). Grades II-IV adverse events were seen in 29% of debulked patients and in 47% of CRS/IPC patients (P = 0.053).CONCLUSIONS:CRS and IPC seems more efficient than debulking surgery and IPC but with numerically higher morbidity. Therefore, if surgically possible, CRS should be the treatment of choice for PMP patients. However, debulking surgery may still be of benefit to selected patients for palliative purposes.

- Purpose: The purpose of this study was to present results on cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) of appendiceal adenocarcinoid (MC) with peritoneal carcinomatosis (PC), to assess drug sensitivity of AAC, as compared with colorectal cancer (CRC), and to report any discordant histopathology. Methods: Ten patients were treated with CRS and HIPEC. Treatment, drug sensitivity profiles, histopathology, and survival data were recorded and matched with potential prognostic indicators. Drug sensitivity was assessed with short-term fluorometric microculture cytotoxicity assay and compared with peritoneal metastases from CRC. Results: Patients with completeness of cytoreduction score (CC) 1 (16.4 months). In the CC 1 group. For standard drugs, tumor cells from MC and CRC were equally sensitive; except for docetaxel, to which MC was more sensitive than CRC. Conclusion: The CC-score correlated with overall survival. Candidates for this type of treatment should be referred early for evaluation in order to reach a better CC score. Drugs used for CRC also seem adequate for treatment of MC, although other drugs, eg, docetaxel, might be more active.

Intraputamenal Cerebral Dopamine Neurotrophic Factor in Parkinson's Disease: A Randomized, Double-Blind, Multicenter Phase 1 Trial

- Background: Cerebral dopamine neurotrophic factor (CDNF) is an unconventional neurotrophic factor that protects dopamine neurons and improves motor function in animal models of Parkinson's disease (PD). Objective: The primary objectives of this study were to assess the safety and tolerability of both CDNF and the drug delivery system (DDS) in patients with PD of moderate severity. Methods: We assessed the safety and tolerability of monthly intraputamenal CDNF infusions in patients with PD using an investigational DDS, a bone-anchored transcutaneous port connected to four catheters. This phase 1 trial was divided into a placebo-controlled, double-blind, 6-month main study followed by an active-treatment 6-month extension. Eligible patients, aged 35 to 75 years, had moderate idiopathic PD for 5 to 15 years and Hoehn and Yahr score ≤ 3 (off state). Seventeen patients were randomized to placebo (n = 6), 0.4 mg CDNF (n = 6), or 1.2 mg CDNF (n = 5). The primary endpoints were safety and tolerability of CDNF and DDS and catheter implantation accuracy. Secondary endpoints were measures of PD symptoms, including Unified Parkinson's Disease Rating Scale, and DDS patency and port stability. Exploratory endpoints included motor symptom assessment (PKG, Global Kinetics Pty Ltd, Melbourne, Australia) and positron emission tomography using dopamine transporter radioligand [18F]FE-PE2I. Results: Drug-related adverse events were mild to moderate with no difference between placebo and treatment groups. No severe adverse events were associated with the drug, and device delivery accuracy met specification. The severe adverse events recorded were associated with the infusion procedure and did not reoccur after procedural modification. There were no significant changes between placebo and CDNF treatment groups in secondary endpoints between baseline and the end of the main and extension studies. Conclusions: Intraputamenally administered CDNF was safe and well tolerated, and possible signs of biological response to the drug were observed in individual patients. © 2023 The Authors.

Tidskriftsartikel (refereegranskat)abstract
- Background: In order to strengthen local alcohol prevention work in Sweden the Swedish government has for the past almost 15years commissioned the Public Health Agency of Sweden to initiate a series of community-based alcohol prevention projects. The latest of these, labeled local development with ambitions (LUMA), included 25 municipalities in Sweden. Objectives: Aim of this study is to examine if LUMA municipalities that received financial support, with requirements, increased local alcohol prevention and if alcohol consumption and harm declined. Methods: Twenty-five Swedish municipalities that received financial support aiming to strengthen local alcohol preventing activities (intervention group) were compared to municipalities that did not receive such support (control group, N = 224), before, during, and after the intervention period. Two composite measures of policy and activity were created and used. The composite activity measure includes seven activity indicators and the composite policy measure includes six policy indicators. Harm measures have been selected based on several recommended indicators for monitoring alcohol, tobacco, and other drugs in Sweden. A fixed effects model was used to analyze data. Results: The results reveal that prevention activities increased and several alcohol-related harm indicators were reduced in intervention municipalities (LUMA) compared with in control municipalities. Conclusions: It seems as if financial support, combined with specific requirements and support from the regional and national level, can stimulate local alcohol prevention activities and have a significant effect on alcohol consumption and alcohol-related harm. Similar evaluations in other countries would be of great value for assessing the generalizability of findings.
