Abstract Background: Parvoviral enteritis is a viral gastrointestinal (GI) infection of dogs. Recovery from PE has been associated with persistent GI signs. The objectives of this study were: (i) To determine whether dogs that have recovered from PE (post-parvo dogs) had an increased risk of persistent GI signs compared to uninfected controls. (ii) To investigate the lifestyle and clinicopathologic factors that are associated with persistent GI signs in post-parvo dogs. Methods: Eighty-six post-parvo dogs and 52 age-matched control dogs were enrolled in this retrospective cohort study. The owners were interviewed about the health and habits of their dogs using a questionnaire. We used logistic regression to test whether parvovirus enteritis and other risk factors are associated with general health problems in all dogs and with persistent GI signs in post-parvo dogs.Results: The prevalence of persistent GI signs was significantly higher in post-parvo dogs compared to control dogs (57% vs 25%, P < 0.001). Markers of disease severity such as neutropenia, low body temperature, and treatment with an antiemetic medication (metoclopramide) were significant risk factors for persistent GI signs in post-parvo dogs. Persistent GI signs in post-parvo dogs was a risk factor for health problems in other organ systems.Conclusions: Parvovirus enteritis is a significant risk factor for persistent GI signs in dogs highlighting the importance of prevention. The risk factors identified in the present study may guide future investigations on the mechanisms that link parvovirus enteritis to chronic health problems in dogs.

Objective: Our primary objective is to give weight to the unanswered and recently heavily debated question, as to whether endometriosis is a statistically significant risk factor for ectopic pregnancy. Our study also provides information on the ethnicity, age and parity of each woman. We report the clinical presentation, the presence of other risk factors as well as intraoperative findings. Design: A retrospective cohort study. Settings: Whipps Cross University Hospital, Bart’s Health NHS Trust which is a district general University hospital in East London. Population: All women, over 10-year period (2005–2014), who were surgically treated for an ectopic pregnancy. Methods: In total, 800 patients were surgically managed. A total of 100 had incomplete data and were, therefore, excluded from analysis. The clinical details, demographics and operation notes were retrospectively analysed for 700 patients. Data were analysed using the student’s t test or chi-square analysis as appropriate. Results: In total, 37 women (5.3%) had endometriosis and 663 women (94.7%) had no evidence of endometriosis. Of the 37 patients, 24 had stage 1, 11 had stage 2 and 2 patients had stage 3 endometriosis. Conclusion: Our data support the theory that endometriosis is not a statistically significant occurrence in women with surgically managed ectopic pregnancy and is not risk factor for ectopic pregnancy.

Long Term Mortality

(1) Background: The aims of this study were to examine the incidence of lower extremity amputations (LEAs) among patients with type 2 diabetes mellitus (T2DM) and to compare the mortality risk of diabetic individuals who underwent LEA with age and sex-matched diabetic individuals without LEA. (2) Methods: We performed a descriptive observational study to assess the trend in the incidence of LEA and a retrospective cohort study to evaluate whether undergoing LEA is a risk factor for long-term mortality among T2DM patients. Data were obtained from the Hospital Discharge Database for the Autonomous Community of Madrid, Spain (2006–2015). (3) Results: The incidence rates of major below-knee and above-knee amputations decreased significantly from 24.9 to 17.1 and from 63.9 to 48.2 per 100000 T2DM individuals from 2006 to 2015, respectively. However, the incidence of minor LEAs increased over time. Mortality was significantly higher among T2DM patients who underwent LEA compared with those who did not undergo this procedure (HR 1.75; 95% CI 1.65–1.87). Male sex, older age, and comorbidity were independently associated with higher mortality after LEA. (4) Conclusions: Undergoing a LEA is a significant risk factor for long term mortality among T2DM patients, and those who underwent a major above-knee LEAs have the highest risk.

Surgical Evacuation

Background: Antithrombosis (AT), with antiplatelets or anticoagulants, is a significant risk factor for the development of chronic subdural hematomas (cSDH). Resumption of AT following hematoma evacuation is variable, with scant evidence for guidance. Methods: We retrospectively analyzed 479 patients with surgically-evacuated cSDH at St. Michael’s Hospital from 2007-2012. Collected variables included type of AT, indication for AT, timing and type of postoperative complications, and restart intervals for AT agents. Postoperative complications were classified as major or minor hemorrhages, or thromboembolism. Results: Among all patients, 14.8% experienced major hemorrhage, 23.0% minor hemorrhage, and 1.67% thromboembolism. Patients on any preoperative AT were at higher risk of major hemorrhage (OR=1.93, p=0.014), experienced earlier major hemorrhage (mean 16.2 versus 26.5d, p=0.052) and earlier thromboembolism (mean 2.7 versus 51.5d, p=0.036). The type of agent did not affect complication frequency or timing. Patients restarted on any AT postoperatively were at decreased risk of major rebleed following resumption, than those not restarted (OR=0.06, p<0.01). Conclusions: Patients on preoperative AT experienced thromboembolism significantly earlier, at 3d postoperatively, with no increase in rebleed risk following AT resumption. We provide cursory evidence that resuming AT early, at 3d postoperatively, may be safe. Larger prospective studies are required for definitive recommendations.

The Impact

Background Hypothyroidism affects 3% of pregnant women, and to date, no studies have addressed the impact levothyroxine-treated hypothyroidism on delivery outcome. Methods This retrospective cohort study was conducted among 750 women with a singleton pregnancy who gave birth between 2015 and 2019. Delivery modes were compared between 250 hypothyroid women exposed to levothyroxine and 500 euthyroid control women. The aim of this study was to determine the impact of levothyroxine exposure on delivery outcome. Results Multiple logistic regression showed no significant association between exposure to levothyroxine and the overall rate of caesarean delivery (aOR 1.1; 95% CI 0.8 to 1.6). Mean TSH concentrations were significantly higher throughout the pregnancy in hypothyroid women despite levothyroxine treatment. Maternal and neonatal outcomes in both groups were not different. Conclusion Hypothyroidism treated with levothyroxine during pregnancy according to local guidelines is not a significant risk factor for caesarean delivery.
