Whether prevention strategy for postoperative venous thromboembolism (VTE) should be tailored across racial groups remains unknown.

Patients who underwent major abdominal operation in the Nationwide Inpatient Sample (NIS) were examined. Our primary outcome was postoperative VTE, and the secondary outcome was postoperative bleeding. Multivariable logistic regression analyses were performed and validated with the National Surgical Quality Improvement Program (NSQIP) database.

781,888 patients from NIS were analyzed. Overall VTE rate was 2.0%. Compared to White patients, Hispanic (OR 0.85, 95% CI 0.78-0.93, p<0.01) and Asian patients (OR 0.49, 95% CI 0.40-0.61, p<0.01) had significantly lower risks for VTE. In contrast, Asian patients had a significantly higher risk of bleeding (OR 1.39, 95% CI 1.24-1.56, p<0.01). Similar trends were observed in NSQIP.

The risk-benefit ratio of postoperative VTE prophylaxis for Asian patients is roughly three times higher than that for White patients, suggesting a tailored approach is necessary.

First bite syndrome (FBS) is an orofacial pain condition characterized by moderate to severe unilateral facial pain associated with the first bite or taste of food. It is important that dentists and physicians be aware of patient history and examination findings commonly associated with FBS, as well as treatment options available for managing this condition.

Described here is a case of FBS arising in a 43-year-old man after partial parotidectomy for the treatment of a mucoepidermoid carcinoma. His orofacial pain was being successfully treated by injection of onabotulinumtoxin A into the residual parotid tissue.

Onabotulinumtoxin A is a promising therapeutic option for FBS owing to its profound relief of pain and minimal reported adverse effects. Therefore, oral health care providers treating FBS should be aware of this option.

To investigate the trend and outcomes of acute pulmonary embolism (PE) during pregnancy and puerperium using a large national database.

The National Inpatient Sample was queried to identify pregnancy-related hospitalizations in the United States from January 1, 2007, through September 30, 2015. Temporal trends in the rates of acute PE and in-hospital mortality rates were extracted.

Among 37,524,314 hospitalizations, 6,333 patients (0.02%) had acute PE. The prevalence of comorbidities and risk factors such as hypertension, obesity, and smoking increased, but rates of acute PE did not change significantly (18.01 in 2007 vs 19.36 in 2015, per 100,000 hospitalizations, P

=.21). Advanced therapies were used in a small number of women (systemic thrombolysis 2.4%, surgical pulmonary embolectomy 0.5%, and inferior vena cava filter in 8.3%). Rates of in-hospital mortality were almost 200-fold higher among those who had acute PE (29.3 vs 0.13, per 1000 pregnancy-related, P<.001). The rate of in-hospital mortality did not change among women with acute PE (2.6% in 2007 vs 2.5% in 2015, P

=.74).

In this contemporary analysis of pregnancy-related hospitalizations, acute PE was uncommon, but rates have not decreased over the past decade. Acute PE during pregnancy and puerperium was associated with high maternal mortality, and the rates of in-hospital mortality have not improved. Future studies to improve prevention and management of acute PE during pregnancy and puerperium are warranted.

D-dimer levels are elevated in COVID 19 and they correlate to the levels of other inflammatory markers such us ferritin, fibrinogen and C-reactive protein. It may be possible to correct D-dimer value in function of inflammatory markers, thus identifying patients at higher risk of venous thromboembolism (VTE). Our objectives are estimating a corrected value of plasma D-dimer as a linear function of ferritin, C-reactive protein and fibrinogen and stablishing a cut-off point of high probability of VTE.

Age and sex matched case-control study of all patients diagnosed with COVID 19 and VTE between March and May 2020 in a tertiary hospital in Madrid (Spain). Using linear regression, the best predictive model will be estimated and residual D-dimer values will be obtained and analyzed using ROC curves to determine its discriminative performance.

Thirty-eight cases and seventy-six controls were included. There was 63.2% of men and mean age was 68.2. D-dimer was best predicted by a linear model including fibrinogen, ferritin and C-reactive protein. Using residual values, the optimal cutoff point was 2165ng/mL, with a sensitivity of 57.9% and specificity of 98.7%.

It is possible to estimate a D-dimer corrected value in function of ferritin, C-reactive protein and fibrinogen. Using the observed and estimated value we can obtain a residual value that performs well as a screening method to detect patients who would benefit for further VTE diagnostic testing.

To assess the influence of systematically varying concentrations of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) versus 3% 4-META on the polymerisation kinetics and shrinkage, biaxial flexural strength (BFS) and modulus of remineralising composites.

Composites were prepared by adding poly(propylene glycol) dimethacrylate (24 wt%), camphorquinone (1 wt%) and MDP (0%, 5%, 10%, 15% and 20 wt%) or 4-META (3%) to urethane dimethacrylate. These were mixed with glass fillers containing 8 wt% monocalcium phosphate and 4 wt% polylysine (powder-liquid ratio of 31). Continuous spectral changes, following 20 s light exposure (37 °C), were assessed with an ATR-FTIR to monitor polymerisation kinetics (n = 3). Final extrapolated conversions (D

) were employed to calculate polymerisation shrinkage. Infigratinib mw BFS and modulus of 24-h dry stored disc specimens (10 × 1 mm; n = 10) were determined using a ball-on-ring jig setup.

Maximum rate of polymerisation and D

increased linearly from 2.5 to 3.5% s

and 67 to 83%, respectively, upon increasing MDP from 0 to 20 wt%.
