Major depression can be treated by means of cognitive behavior therapy, delivered via the Internet as guided self-help. Individually tailored guided self-help treatments have shown promising results in the treatment of anxiety disorders. This randomized controlled trial tested the efficacy of an Internet-based individually tailored guided self-help treatment which specifically targeted depression with comorbid symptoms. The treatment was compared both to standardized (non-tailored) Internet-based treatment and to an active control group in the form of a monitored online discussion group. Both guided self-help treatments were based on cognitive behavior therapy and lasted for 10 weeks. The discussion group consisted of weekly discussion themes related to depression and the treatment of depression. A total of 121 participants with diagnosed major depressive disorder and with a range of comorbid symptoms were randomized to three groups. The tailored treatment consisted of a prescribed set of modules targeting depression as well as comorbid problems. The standardized treatment was a previously tested guided self-help program for depression. From pre-treatment to post-treatment, both treatment groups improved on measures of depression, anxiety and quality of life. The results were maintained at a 6-month follow-up. Subgroup analyses showed that the tailored treatment was more effective than the standardized treatment among participants with higher levels of depression at baseline and more comorbidity, both in terms of reduction of depressive symptoms and on recovery rates. In the subgroup with lower baseline scores of depression, few differences were seen between treatments and the discussion group. This study shows that tailored Internet-based treatment for depression is effective and that addressing comorbidity by tailoring may be one way of making guided self-help treatments more effective than standardized approaches in the treatment of more severe depression.

Background Laparoscopic gastrectomy is increasingly used for the treatment of locally advanced gastric cancer but concerns remain whether similar results can be obtained compared to open gastrectomy, especially in Western populations. This study compared the short-term postoperative, oncological and survival outcomes following laparoscopic versus open gastrectomy based on data from the Swedish National Register for Esophageal and Gastric Cancer. Methods Patients who underwent surgery with curative intent for adenocarcinoma of the stomach or gastroesophageal junction Siewert type III from 2015 to 2020 were identified, and 622 patients with cT2-4aN0-3M0 tumors were included. The impact of surgical approach on short-term outcomes was assessed using multivariable logistic regression. Long-term survival was compared using multivariable Cox regression. Results In total, 350 patients underwent open and 272 laparoscopic gastrectomy, of which 12.9% were converted to open surgery. The groups were similar regarding distribution of clinical disease stage (27.6% stage I, 46.0% stage II, and 26.4% stage III). Neoadjuvant chemotherapy was administered to 52.7% of the patients. There was no difference in the rate of postoperative complications, but laparoscopic approach was associated with lower 90 day mortality (1.8 vs 4.9%, p  = 0.043). The median number of resected lymph nodes was higher after laparoscopic surgery (32 vs 26, p  < 0.001), while no difference was found in the rate of tumor-free resection margins. Better overall survival was observed after laparoscopic gastrectomy (HR 0.63, p  < 0.001). Conclusions Laparoscopic gastrectomy can be safely preformed for advanced gastric cancer and is associated with improved overall survival compared to open surgery.

Post-fire studies conducted by NIST on the Waldo Canyon Fire in Colorado (2012) determined that wood fencing assemblies are believed to be vulnerable to ignition from firebrand showers in Wildland–Urban Interface fires, but again there has never been any experimental verification of this ignition mechanism. As a result, a series of experiments were conducted to examine ignition of wood fencing assemblies subjected to continuous, wind-driven firebrand showers. Western Red Cedar and Redwood fencing assemblies were exposed to continuous, wind-driven firebrands generated by the NIST full-scale Continuous Feed Firebrand Generator installed in the Fire Research Wind Tunnel Facility at the Building Research Institute in Japan. To simulate fine fuels that may be present near fencing assemblies, dried shredded hardwood mulch beds were placed adjacent to the fencing assemblies. The fencing assemblies were varied in length and in orientation to the applied wind field to simulate a range of configurations that may be encountered in realistic situations. Both flat and corner sections of fencing assemblies were used in these experiments. The dimensions of the flat wood fencing assemblies sections were varied from 0.91 m wide, 1.83 m in height to 1.83 m wide, 1.83 m in height. With respect to the corner sections, the dimensions used were 0.91 m by 0.91 m by 1.83 m in height. All configurations considered resulted in flaming ignition (FI) of the mulch beds, and subsequent FI of the wood fencing assemblies. Finally, experiments were also completed to determine if wind-driven firebrand showers could produce FI of fencing assemblies without the presence of fine fuels adjacent to the fence sections. Firebrands produced smoldering ignition (SI) of the fencing assemblies without fine fuels present, and SI transitioned to FI under the applied wind field. These experiments have demonstrated that wood fencing assemblies are vulnerable to ignition by wind-driven firebrand showers.

Introduction Stent migration is a significant clinical problem in palliation of malignant strictures in the esophagus and gastro-esophageal junction (GEJ). We have compared a newer design of a fully-covered stent to a widely used semi-covered stent using migration >20 mm as the primary outcome variable. Effects on dysphagia, quality of life (QoL) and re-intervention frequency were also investigated. Methods Patients with dysphagia due to non-curable esophagus/GEJ cancer were randomized to receive either a more recent design of a fully-covered stent (n = 48) or a conventional semi-covered stent (n = 47). Chest x-ray, dysphagia and QoL were studied at baseline, one week, four weeks and three months thereafter. Results There were no significant differences either in stent migration distance or in the migration frequency. Stent migration during the total study period occurred in 37.2 % in the semi-covered group compared to 20.0 % for the fully-covered group. Dysphagia was measured with Watson and Ogilvie scores and with the dysphagia module in the QoL scale (QLQ-OG25). On average, there was a tendency to better dysphagia relief for the fully-covered design as scored with the two latter dysphagia instruments (p= 0.081 and p= 0.067) at three months and towards more re-interventions in the semi-covered group (p= 0.083). Conclusion In spite of its somewhat lower intrinsic radial force, the fully-covered stent was comparable to the conventional semi-covered stent with regard to stent migration. The data further suggest a potential benefit of the fully-covered stent in improving dysphagia in patients with longer life expectancy.

Background This study compares the long-term results of pneumatic dilatations versus laparoscopic myotomy using treatment failure as the primary outcome. The frequency and degree of dysphagia, the effects on quality of life (QoL), and health economy were also examined. Methods Fifty-three patients with achalasia were randomized to laparoscopic myotomy with a posterior partial fundoplication [laparoscopic myotomy (LM) n  = 25] or repetitive pneumatic dilatation [pneumatic dilatation (PD) n  = 28]. The median observation period was 81.5 months (range 12–131). Results At the minimal follow-up of 5 years, ten patients (36 %) in the dilatation group and two patients (8 %) in the myotomy group, including two patients lost to follow-up (one in each arm), were classified as failures ( p  = 0.016). The cumulative incidence of treatment failures was analyzed by survival statistics. Taking the entire follow-up period into account, a significant difference was observed in favor of the LM strategy ( p  = 0.02). Although both treatments resulted in significant improvements in dysphagia scores, LM was significantly favored over PD after 1 and 3 years, but not after 5 years. Health-related QoL assessed by the personal general well being score was higher in the LM group after 3 years, but the difference was not fully statistically significant at 5 years. Direct medical costs during the entire follow-up period were in median $13,421 for LM as compared to $5,558 for PD ( p  = 0.001). Conclusions This long-term follow-up of a randomized clinical study shows that LM is superior to repetitive PD treatment of newly diagnosed achalasia, albeit that this surgical strategy is burdened by high initial direct medical costs. www.ClinicalTrials.gov NCT 02086669

Background and objectivesThe most efficient long-term treatment strategy for achalasia has yet to be established. This study compared the long-term results (≥ 10 years) after either pneumatic dilatations or laparoscopic myotomy using treatment failure as the primary outcome. Secondary objectives were; the frequency and degree of dysphagia and effects on health-related quality of life (QoL).Patients and methodsOut of the 53 patients with achalasia who were initially randomized to either laparoscopic myotomy with a posterior partial fundoplication (LM) or repetitive pneumatic dilatation (PD), 43 remained for scrutiny after a median observation period of 170 months (LM; n = 20 and PD; n = 23).ResultsAt the follow-up of 60 months, 10 patients (36%) in the PD group and two patients (8%) in the LM group were classified as treatment failures (p = 0.016). At the latest follow-up time point (≥ 10 years), the corresponding numbers were 13 (57%) and 4 (20%), respectively. The Kaplan–Meier analysis of the cumulative incidence of treatment failure revealed a significant advantage of LM over the dilatation strategy (p = 0.036)). QoL assessed by the generic instrument PGWB and the more disease-specific instrument GSRS revealed scores which were similar in the two study groups with no obvious changes over time. Reflux was better controlled in the LM group (p = 0.02 regarding PPI consumption).ConclusionsAfter more than a decade of follow-up, laparoscopic myotomy reinforces its superiority over repetitive pneumatic dilatation treatment strategy in the management of newly diagnosed achalasia.

Background Randomized studies have indicated that acute appendicitis may be treated by antibiotics without the need of surgery. However, concerns have been raised about selection bias of patients in such studies. Therefore, the present study was aimed to validate previous findings in randomized studies by a full-scale population-based application. Methods All patients with acute appendicitis at Sahlgrenska University Hospital (May 2009 and February 2010) were offered intravenous piperacillin plus tazobactam according to our previous experience, followed by 9 days out-hospital oral ciprofloxacin plus metronidazole. Endpoints were treatment efficacy and complications. Efficient antibiotic treatment was defined as recovery without the need of surgery beyond 1 year of follow-up. Results A total of 558 consecutive patients were hospitalized and treated due to acute appendicitis. Seventy-nine percent ( n  = 442) received antibiotics as first-line therapy and 20 % ( n  = 111) had primary surgery as the second-line therapy. Seventy-seven percent of patients on primary antibiotics recovered while 23 % ( n  = 100) had subsequent appendectomy due to failed initial treatment on antibiotics. Thirty-eight patients (11 %) of the 342 had experienced recurrent appendicitis at 1-year follow-up. Primary antibiotic treatment had fewer complications compared to primary surgery. Conclusions This population-based study confirms previous results of randomized studies. Antibiotic treatment can be offered as the first-line therapy to a majority of unselected patients with acute appendicitis without medical drawbacks other than the unknown risk for long-term relapse, which must be weighed against the unpredicted but well-known risk for serious major complications following surgical intervention.

The most effective therapeutic strategy in newly diagnosed achalasia is yet to be established. Therefore we designed a study in which pneumatic dilatation was compared to laparoscopic cardiomyotomy to which was added a partial posterior fundoplication. A series of 51 patients (24 males, mean age 44 years) were randomly allocated to the therapeutic modalities (dilatation = 26, surgery = 25). All patients were followed for at least 12 months, and during that period the pneumatic dilatations strategy had significantly more treatment failures (P = 0.04). Only minor differences emerged between the study groups when symptoms, dysphagia scorings, and quality-of-life assessments were evaluated 12 months after initiation of therapy. Laparoscopic myotomy was found to be superior to an endoscopic balloon dilatation strategy in the treatment of achalasia when studied during the first 12 months after treatment.

Gastroduodenal outlet obstruction is a complication of advanced gastrointestinal malignant disease. In the past it was usually treated by an open surgical bypass procedure. During the last decade, endoscopic self‐expandable stents (SEMS) have been used. The aim of this study was to compare these two palliative strategies concerning clinical outcome and health economy. A series of 36 patients with incurable malignant disease and gastroduodenal outlet obstruction syndrome were treated in a prospective study. According to the attending hospital and endoscopist on duty, 21 of the 36 patients were endoscopically treated with SEMS and 15 underwent an open surgical gastroenteroanastomosis. Health economic evaluation was based on the monetary charges for each patient associated with the procedure, postoperative care, and hospital stay. The hospital stay was 7.3 days for the stented group compared with 14.7 days for the open surgery group (p > 0.05). The survivals were 76 and 99 days, respectively (NS). In the stented group all 15 patients (100%) alive after 1 month were able to eat or drink, and 11 (73%) of them tolerated solid food. In the surgical bypass group,9 out of 11 (81%) patients alive after 1 month could eat or drink, and 5 of them (45%) could eat solid food. The mean charges (U.S. dollars) during the hospital stay were$7215 for the stented group and $ 10,190 for the open surgery group (p < 0.05). Palliation of the gastroduodenal obstruction in patients with malignant disease were at least as good, and the charges were lower for the endoscopic stenting procedure than for an open surgical bypass.

Tumour recurrence that obstructs the afferent limb, blocking outflow of bile and pancreatic juice, constitutes a major clinical problem after a Whipple procedure. The endoscopic route is often not a possible alternative. Surgery may be difficult and perhaps dangerous to the often very sick patient and decompression with fine bore catheters may lead to cholangitis. External drainage is inconvenient to the patient. The present case describes a less invasive method to provide adequate drainage of the obstructed jejunal limb by insertion of a 22-mm enteral Wallstent transhepatically. The patient became and stayed anicteric during 7 months’ follow-up.
