Abstract
BACKGROUND Despite its potential for usefulness in informing the development of smoking cessation interventions, short-term fluctuations in motivation to quit is a relatively understudied topic. OBJECTIVES To assess the prevalence of smokers' day-to-day fluctuations in motivation to quit, and to assess associations of day-to-day fluctuations in motivation to quit with several established cessation-related variables. METHODS A cross-sectional survey was administered to smokers in Hawaii (N = 1,567). To assess short-term fluctuations in motivation to quit smoking, participants were asked to respond "True" or "False" to the statement: "My motivation to quit smoking changes from one day to the next." Other items measured desire to quit smoking, intention to quit, confidence in quitting, cigarette dependence, and other cessation-related variables. RESULTS "My motivation to quit smoking changes from one day to the next" was endorsed as true by 64.7% of smokers, and false by 35.3%. Analyses revealed that smokers who indicated fluctuating motivation were significantly more interested in quitting as compared to smokers without fluctuations. Fluctuations in motivation to quit also were associated with greater confidence in quitting, lesser cigarette dependence, and more recent quitting activity (all p < .01). CONCLUSIONS Day-to-day fluctuations in motivation to quit are common. Day-to-day fluctuations in motivation to quit are strongly associated with higher motivation to quit, greater confidence in future quitting, and other positive cessation-relevant trends.

Abstract
Betel quid is a psychoactive drug preparation typically made up of a combination of areca quid, slaked lime, piper betel leaf and tobacco. It is the fourth most commonly consumed drug in the world with global use concentrated in the Asia-Pacific region (Boucher and Mannan, 2002; Warnakulasuriya and Peters, 2002). The International Agency for Research on Cancer has classified betel quid as a Group 1 carcinogen (IARC, 2004; Lin et al., 2006), and its use has been associated with oral and oropharyngeal cancer, oral lesions, oral leukoplakia, submucous fibrosis, gum disease, and cancer of the pharynx and esophagus (IARC, 2004; Oakley et al., 2005; Shah et al., 2002; Warnakulasuriya, 2002). This paper reports on the feasibility of an innovative betel quid cessation program carried on the U.S. territory of Guam, and is the first of its kind. The program is described, along with the challenges encountered during the implementation process.

Abstract
BACKGROUND After pancreatic head resection the reconstruction of small and fragile bile ducts is technically demanding, resulting in more postoperative bile leaks. One option for the reconstruction is the placement of a T-tube drainage at the site of the anastomosis. MATERIAL AND METHODS Standard reconstruction after pancreatic head resection was an end-to-side hepaticojejunostomy with PDS 5.0, 15-25 cm distally from the pancreaticojejunostomy. For patients with a small bile duct diameter (≤ 5 mm) or a fragile bile duct wall the reconstruction was performed with PDS 6.0 and a T-tube drainage at the side of the anastomosis. RESULTS The reconstruction with a T-tube drainage at the site of the anastomosis is technically easy to perform and offers the opportunity for immediate visualisation of the anastomosis in the postoperative period by application of water soluble contrast medium. If a bile leak occurs, biliary deviation through the T-tube drainage can enable a conservative management without revisional laparotomy in selected patients. Whether or not a conservative management of postoperative bile leaks will lead to more bile duct strictures is a subject for further investigations. CONCLUSION A T-tube drainage at the site of the anastomosis can probably not prevent postoperative bile leaks from a difficult hepaticojejunostomy, but in selected patients it offers the opportunity for a conservative management resulting in less re-operations. Therefore we recommend the augmentation of a difficult hepaticojejunostomy with a T-tube drainage.

Abstract
Background The concept of total mesorectal excision has revolutionised rectal cancer surgery. TME reduces the rate of local recurrence and tumour associated mortality. However, in clinical trials only 50% of the removed rectal tumours have an optimal TME quality. Patients: During a period of 36 months we performed 103 rectal resections. The majority of patients (76%; 78/103) received an anterior resection. The remaining patients underwent either abdominoperineal resection (16%; 17/103), Hartmann's procedure (6%; 6/103) or colectomy (2%; 2/103). Results In 90% (93/103) TME quality control could be performed. 99% (92/93) of resected tumours had optimal TME quality. In 1% (1/93) the mesorectum was nearly complete. None of the removed tumours had an incomplete mesorectum. In 98% (91/93) the circumferential resection margin was negative. Major surgical complications occurred in 17% (18/103). 5% (4/78) of patients with anterior resection had anastomotic leakage. 17% (17/103) developed wound infections. Mortality after elective surgery was 4% (4/95). Conclusion Optimal TME quality results can be achieved in all stages of rectal cancer with a rate of morbidity and mortality comparable to the results from the literature. Future studies should evaluate outcome and local recurrence in accordance to the degree of TME quality.

Abstract
Damage to peripheral nerve branches triggers activation of microglia in CNS areas containing motor neuron soma and primary afferent terminals of the damaged fibers. Furthermore, microglial activation occurs in areas containing the soma and terminals of spared nerve branches of a damaged nerve. Because the abdominal viscera are innervated by spinal afferents as well as vagal afferents and efferents, we speculated that spinal nerves might respond like spared nerve branches following damage to vagal fibers. Therefore, we tested the hypothesis that damage to the abdominal vagus would result in microglial activation in vagal structures-the nucleus of the solitary tract (NTS), dorsal motor nucleus of the vagus nerve (DMV), and nodose ganglia (NG)-as well as spinal cord (SC) segments that innervate the abdominal viscera. To test this hypothesis, rats underwent subdiaphragmatic vagotomy or sham surgery and were treated with saline or the microglial inhibitor, minocycline. Microglial activation was determined by quantifying changes in the intensity of fluorescent staining with a primary antibody against ionizing calcium adapter binding molecule 1 (Iba1). We found that subdiaphragmatic vagotomy significantly activated microglia in the NTS, DMV, and NG two weeks post-vagotomy. Microglial activation remained significantly increased in the NG and DMV for at least 42 days. Surprisingly, vagotomy significantly decreased microglial activation in the SC. Minocycline treatment attenuated microglial activation in all studied areas. Our results indicate that microglial activation in vagal structures following abdominal vagal damage is accompanied by suppression of microglial activation in associated areas of the spinal cord.

Abstract
INTRODUCTION Diverticular disease of the colon is a common condition in developed countries. For perforated diverticulitis Hartmann's procedure is a safe and quick treatment option. But intestinal restoration needs further interventions. This leads to high complication rates and cost. Therefore a critical evaluation of surgical treatment options is necessary. METHODS During a period of 18 months 88 patients underwent surgical resection for diverticulitis. Forty patients had emergency surgery. Among those a primary anastomosis was performed in 21 patients. The other 19 patients had interval colostomy. Among 21 patients with primary anastomosis major complications occurred in two patients, vs. twelve in patients with Hartmann's operation (p = 0.03). In the Hartmann group eight patients had major general complications, vs. one patient in the group with primary anastomosis (p = 0.06). The mean hospital stay was 38 days after Hartmann's procedure, vs. 13 days for patients with primary anastomosis (p < 0.01). CONCLUSION In emergency surgery for complicated diverticulitis primary anastomosis is not associated with an increased postoperative morbidity. A primary anastomosis reduces the need for further surgical interventions and complex re-operations. Thus, an overall reduction of morbidity, cost, complication rate and hospital stay is possible. Therefore this technique is advantageous for patients and hospitals.

Abstract
The stage of change approach to smoking cessation posits that smokers can be divided into categories based on the extent to which they are motivated to quit smoking. Recent research, however, suggests that the stage of change algorithm systematically misclassifies smokers by underestimating motivation to quit. The hypothesis of the current study was that the systematic misclassification by the stages of change results in stages that blend together smokers varying widely in motivation to quit. We tested this hypothesis by contrasting the stages of change with the contemplation ladder (an alternative measure of motivation to quit smoking) using cross-sectional data on ten cessation-relevant variables. The sample consisted of 401 adolescent smokers. The results were consistent with the hypothesis. The cross-sectional analyses indicated that the contemplation ladder is a more discriminating measure of motivation to quit, and that the stage of change algorithm is an unnecessarily imprecise instrument.
