TL;DR: It is demonstrated that IL‐22, in contrast to its relative IFN‐γ, regulates the expression of only a few genes in keratinocytes, which may be important in the innate immunity and reorganization of epithelia.
Abstract: IL-22 is an IFN-IL-10 cytokine family member, which is produced by activated Th1 and NK cells and acts primarily on epithelial cells. Here we demonstrate that IL-22, in contrast to its relative IFN-gamma, regulates the expression of only a few genes in keratinocytes. This is due to varied signal transduction. Gene expressions regulated by IL-22 should enhance antimicrobial defense [psoriasin (S100A7), calgranulin A (S100A8), calgranulin B (S100A9)], inhibit cellular differentiation (e.g., profilaggrin, keratins 1 and 10, kallikrein 7), and increase cellular mobility [e.g., matrix metalloproteinease 1 (MMP1, collagenase 1), MMP3 (stromelysin 1), desmocollin 1]. In contrast, IFN-gamma favored the expression of MHC pathway molecules, adhesion molecules, cytokines, chemokines, and their receptors. The IL-22 effects were transcriptional and either independent of protein synthesis and secretion, or mediated by a secreted protein. Inflammatory conditions, but not keratinocyte differentiation, amplified the IL-22 effects. IL-22 application in mice enhanced cutaneous S100A9 and MMP1 expression. High IL-22 levels in psoriatic skin were associated with strongly up-regulated cutaneous S100A7, S100A8, S100A9, and MMP1 expression. Psoriatic patients showed strongly elevated IL-22 plasma levels, which correlated with the disease severity. Expression of IL-22 and IL-22-regulated genes was reduced by anti-psoriatic therapy. In summary, despite similarities, IFN-gamma primarily amplifies inflammation, while IL-22 may be important in the innate immunity and reorganization of epithelia.

TL;DR: The present data provide Level 2b evidence (Oxford Centre for Evidence-based Medicine) that survival depends on complete resection of enhancing tumor in glioblastoma multiforme and treatment bias was demonstrated regarding resection and second-line therapies.
Abstract: Treatment bias was demonstrated regarding resection and second-line therapies. However, bias and imbalances were controllable in the cohorts available from the 5-aminolevulinic acid study so that the present data now provide Level 2b evidence (Oxford Centre for Evidence-based Medicine) that survival depends on complete resection of enhancing tumor in glioblastoma multiforme.

TL;DR: Although most patients in both treatment groups experienced clinical improvement, the study did not meet its primary objective of showing that MMF was superior to IVC as induction treatment for lupus nephritis.
Abstract: Recent studies have suggested that mycophenolate mofetil (MMF) may offer advantages over intravenous cyclophosphamide (IVC) for the treatment of lupus nephritis, but these therapies have not been compared in an international randomized, controlled trial. Here, we report the comparison of MMF and IVC as induction treatment for active lupus nephritis in a multinational, two-phase (induction and maintenance) study. We randomly assigned 370 patients with classes III through V lupus nephritis to open-label MMF (target dosage 3 g/d) or IVC (0.5 to 1.0 g/m(2) in monthly pulses) in a 24-wk induction study. Both groups received prednisone, tapered from a maximum starting dosage of 60 mg/d. The primary end point was a prespecified decrease in urine protein/creatinine ratio and stabilization or improvement in serum creatinine. Secondary end points included complete renal remission, systemic disease activity and damage, and safety. Overall, we did not detect a significantly different response rate between the two groups: 104 (56.2%) of 185 patients responded to MMF compared with 98 (53.0%) of 185 to IVC. Secondary end points were also similar between treatment groups. There were nine deaths in the MMF group and five in the IVC group. We did not detect significant differences between the MMF and IVC groups with regard to rates of adverse events, serious adverse events, or infections. Although most patients in both treatment groups experienced clinical improvement, the study did not meet its primary objective of showing that MMF was superior to IVC as induction treatment for lupus nephritis.

TL;DR: If the long-term oncological results of Laparoscopic and conventional resection of colonic carcinoma show equivalent results, the laparoscopic approach should be preferred in patients suitable for this approach to colectomy.
Abstract: Background
Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed.
Objectives
This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery).
Search methods
We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004.
We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt fur Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie. Handsearch of abstracts from the following society meetings from 1991 to 2004: American College of Surgeons, American Society of Colorectal Surgeons, Royal Society of Surgeons, British Assocation of Coloproctology, Surgical Association of Endoscopic Surgeons, European Association of Endoscopic Surgeons, Asian Society of Endoscopic Surgeons.
Selection criteria
All randomised-controlled trial were included regardless of the language of publication. No- or pseudorandomised trials as well as studies that followed patient's preferences towards one of the two interventions were excluded, but listed separately. RCT presented as only an abstract were excluded.
Data collection and analysis
Results were extracted from papers by three observers independently on a predefined data sheet. Disagreements were solved by discussion. 'REVMAN 4.2' was used for statistical analysis. Mean differences (95% confidence intervals) were used for analysing continuous variables. If studies reported medians and ranges instead of means and standard deviations, we assumed the difference of medians to be equal to the difference of means. If no measure of dispersion was given, we tried to obtain these data from the authors or estimated SD as the mean or median. Data were pooled and rate differences as well as weighted mean differences with their 95% confidence intervals were calculated using random effects models.
Main results
25 RCT were included and analysed. Methodological quality of most of these trials was only moderate and perioperative treatment was very traditional in most studies. Operative time was longer in laparscopic surgery, but intraoperative blood was less than in conventional surgery. Intensity of postoperative pain and duration of postoperative ileus was shorter after laparoscopic colorectal resection and pulmonary function was improved after a laparoscopic approach. Total morbidity and local (surgical) morbidity was decreased in the laparoscopic groups. General morbidity and mortality was not different between both groups. Until the 30th postoperative day, quality of life was better in laparoscopic patients. Postoperative hospital stay was less in laparoscopic patients.
Authors' conclusions
Under traditional perioperative treatment, lapararoscopic colonic resections show clinically relevant advantages in selected patients. If the long-term oncological results of laparoscopic and conventional resection of colonic carcinoma show equivalent results, the laparoscopic approach should be preferred in patients suitable for this approach to colectomy.
