Venous Thromboembolism Following Colorectal Surgery for Suspected or Confirmed Malignancy
Brenton Sanderson,Kerry Hitos,John P. Fletcher
Thrombosis , 2011, DOI: 10.1155/2011/828030
Abstract: Surgery for colorectal cancer conveys a high risk of venous thromboembolism (VTE). The effect of thromboprophylactic regimens of varying duration on the incidence of VTE was assessed in 417 patients undergoing surgery between 2005 and 2009 for colorectal cancer. Low-dose unfractionated heparin (LDUH) was used in 52.7% of patients, low-molecular-weight heparin (LMWH) in 35.3%, and 10.7% received LDUH followed by LMWH. Pharmacological prophylaxis was continued after hospitalisation in 31.6%. Major bleeding occurred in 4% of patients. The 30-day mortality rate was 1.9%. The incidence of symptomatic VTE from hospital admission for surgery to 12 months after was 2.4%. There were no in-hospital VTE events. The majority of events occurred in the three-month period after discharge, but there were VTE events up to 12 months, especially in patients with more advanced cancer and multiple comorbidities.

Introduction Major surgery conveys a significant risk of venous thromboembolism (VTE), a condition that encompasses both deep vein thrombosis (DVT) and pulmonary embolism (PE). The first-time incidence of VTE in the general population is approximately 100 persons per 100,000 per year [1]. VTE is a common cause of morbidity and mortality in surgical patients which is preventable in the majority of cases with appropriate prophylaxis [1, 2]. There are numerous risk factors for developing VTE and, importantly, for colorectal cancer surgery patients, include increasing age, history of VTE, malignancy and its treatment, and surgery duration [3–5]. The presence of these risk factors places colorectal cancer surgery patients at an increased risk of VTE compared to general surgical patients [5, 6]. A retrospective analysis examined VTE in colorectal cancer patients, 70% of whom underwent surgery, and found a VTE incidence of 3.1% (2,100 patients) at two years [6]. The incidence rate was found to decrease over the two-year period, demonstrating the importance of VTE prophylaxis in the period after diagnosis and perioperatively [6]. The strongest predictors for VTE occurrence in this patient group were found to be the presence of metastatic disease and multiple co-morbidities [6]. In the American College of Chest Physicians (ACCP) evidence-based clinical practice guidelines, colorectal cancer surgery patients are judged as having a high risk of VTE and are recommended to receive both anticoagulant and mechanical VTE prophylaxis unless contraindicated [7]. For anticoagulant prophylaxis, colorectal cancer surgery patients are recommended to receive low-molecular-weight
Incidence and Predictors of Dysphagia Following Anterior Cervical Discectomy and Fusion: Prospective Observational Study  [PDF]

Abstract: The incidence of dysphagia following anterior cervical discectomy and fusion (ACDF) reported in the literature varies due to differences in measures and time intervals applied, ranging from nearly 3/4 at 2 weeks to 13% at 12 months. The most commonly used dysphagia scales remain subjective, non-validated, and do not capture functional impact. Various risk factors have been identified, though few consistently reproduced and none studied in an Australasian context. The aims of this study were to use objective and validated measures, assess both traditional and novel risk factors, and determine the impact of dysphagia on dietary status, length of stay and complications. METHODS: Twenty-nine adults undergoing ACDF for degenerative pathologies were enrolled between March and November 2015 in an Australian institution. Bazaz dysphagia scale, Dysphagia short questionnaire, 3-ounce swallow test and dietary status were assessed preoperatively, and 2 days and 6 weeks postoperatively. Descriptive statistics were used to characterise the study sample and logistic regression modelling performed on risk factors. RESULTS: Dysphagia incidence ranged from 85% on day-2 Dysphagia short questionnaire to zero on 6-week 3-ounce swallow. All measures increased at 2 days and fell by 6 weeks. Failing day-2 3-ounce swallow was the only measure associated with modifications in solids (P = 0.06), showing significant linear correlation (P = 0.02). Respiratory comorbidity increased risk of failing day-2 3-ounce swallow by more than 32-fold (OR: 32.4; 95% CI: 1.8 - 587.7; P = 0.019) and scoring moderate or severe on Bazaz by almost 10-times (OR: 9.3; 95% CI: 0.9 - 95.95; P = 0.061). Psychiatric history also increased risk of failing day-2 3-ounce swallow by more than 10-fold (OR: 10.9; 95% CI: 1 - 123.7; P = 0.054). Failing 3-ounce swallow increased length of stay (5 versus 7 days; P = 0.013). CONCLUSIONS: Incidence of dysphagia following ACDF was dependent on the measure used, though all improved over time. The 3-ounce swallow test correlated with dietary modification and length of stay, while respiratory comorbidity posed the most significant risk. This may identify a group of patients who may benefit from early intervention.

Abstract: Mi media conjetura muestra la paradoja subyacente en la conjetura de Collatz y en general en muchas conjeturas matemáticas, especialmente en el área de la teoría de números: su enunciado puede ser entendido por un ni o, su demostración se resiste a matemáticos de todas las épocas.
Outlooks toward Government Institutions in Quebec  [PDF]
Mebs Kanji, Kerry Tannahill
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.34025
Abstract:

The 2012 Quebec election campaign began with opposition parties claiming that factors such as corruption and false promises (among others) had made Quebecers leery of their government institutions. The time had come to clean house and get the province back on track to good governance and prosperity. In this paper, we employ new data from the Quebec component of the Comparative Provincial Election Project to examine Quebecers’ outlooks toward various government institutions. How confident are Quebecers in their political parties, governments, legislatures and civil service? Is there any evidence to suggest that Quebecers’ views on these specific government institutions are any different across various levels of government? And what accounts for any negativity that Quebecers may feel? More specifically, this analysis considers a variety of plausible explanations, including poor government performance, pervasive cynicism, rising levels of cognitive mobilization, the rise of post-materialist values and declining levels of interpersonal trust, just to name a few.

Outlooks toward Democracy in Quebec  [PDF]
Mebs Kanji, Kerry Lynne Tannahill
Open Journal of Political Science (OJPS) , 2014, DOI: 10.4236/ojps.2014.44031
Abstract: Support for democratic regime principles is generally strong and stable across advanced industrial democracies. However, as groups of society are becoming increasingly informed and critical and certain segments remain widely and consistently left out or disillusioned, opinions of democracy may suffer. Using a unique dataset (the Comparative Provincial Election Study) with a representative sample of Quebec voters, this analysis provides for the first time a more detailed and focused examination of orientations toward the democratic political regime across three different levels of government (national, provincial, and municipal). Our study reveals that, while most Quebecers feel that a democratic political regime is a good way of governing at all levels of government, only slightly more than a majority commit solely to a democratic alternative and sizeable segments are open to other regime types as well. Also, few Quebecers feel that their democracies are working well in practice at all levels. Our analysis also reveals significant variation in terms of specific support for authorities, institutions of government, and the workings of democracy. More specifically, Quebecers have less confidence in their political leaders than in their elected representatives, more confidence in their legislatures and civil service than in governments and political parties, and they have the lowest confidence in most of these objects at the federal level. Finally, our findings show that these negative orientations toward specific political objects have robust and significant negative effects on the way Quebecers feel about how well their democratic communities are working in practice, even while controlling for other theoretically relevant cultural, structural, and contextual factors.
