Surgical trends, outcomes and disparities in minimal invasive surgery for patients with endometrial cancer in England: a retrospective cohort study

ObjectiveTo examine surgical outcomes and trends in the implementation of minimally invasive surgery (MIS) use for endometrial cancer (EC).DesignRetrospective cohort study.SettingEnglish National Health Service hospitals 2011–2017/2018.Population35 304 patients having a hysterectomy for EC identified from Hospital Episode Statistics.MethodsUnivariate and multivariate analyses compared MIS to open hysterectomy (OH) by assessing the association between demographic, clinical and hospital characteristics by using logistic regression. A propensity score was created, to control for confounding factors including demographics, clinical and hospital characteristics, from a logistic regression which enabled the inverse probability weighting of treatment to be applied in order to compare outcomes of treatment.Main outcome measuresThe association between route of surgery on perioperative morbidity and mortality.ResultsThe MIS rate rose from 40.3% in 2011 to 68.7% in 2017/2018, however, there was significant geographical variation (p<0.001). The overall 90-day mortality was significantly higher with OH versus MIS (OR 0.34, 95% CI 0.18 to 0.62, p=0.0002). MIS rates were significantly lower in patients from the lowest socioeconomic group (LSEG) compared with patients from the highest group (HSEG) (55.4% vs 59.9%, p<0.01), and in the black population as compared with white and Asian populations (40.4% vs 58.6% and 56.0%, p<0.0001). When patients from LSEG and black patients were treated in hospitals with high MIS rates, the MIS rate increased close to that of the HSEG and white patients (81.0% and 74.1% vs 83.2% and 82.6%).ConclusionsFurther investigation is needed to understand the barriers to MIS and improve access so that as many patients as possible can benefit from the reduced morbidity/mortality associated with MIS.

Objective To estimate the risk of perioperative morbidity with increasing number of cesareans. Study Design We conducted a retrospective cohort study from 2004 to 2010. Patients delivered by cesarean were included. Outcome measures were a composite organ injury (bowel or bladder), hysterectomy, hemorrhage requiring transfusion, severe morbidity, or surgical site complications. The Cochran–Armitage's test of trend was used to assess increasing incidence of each morbidity with number of prior cesareans. Multivariable logistic regression was used to estimate adjusted risks for each morbidity with increasing number of cesareans compared with primary cesarean. Results Of the 15,872 women in the cohort, 5,144 had cesarean delivery: 3,113 primary, 1,310 one prior, 510 two prior, and 211 three or more prior cesareans. There was a significant increase in organ injury, hysterectomy, and surgical site complications with increasing number of cesareans. In multivariable analysis, the risk of organ injury and hysterectomy was increased compared with primary cesarean after two prior cesareans, and after three or more cesareans for hemorrhage requiring transfusion and surgical site complications. Conclusion The risks of organ injury and hysterectomy are increased after two or more prior cesareans, and risks of hemorrhage and surgical site complications are increased after three or more cesareans.

Abstract Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection can lead to many different cardiovascular complications, we were interested in studying prognostic markers in patients with atrial fibrillation/flutter (A. Fib/Flutter). Methods A retrospective cohort study of patients with confirmed COVID-19 and either with existing or new onset A. Fib/Flutter who were admitted to our hospital between March 15 and May 20, 2020. Demographic, outcome and laboratory data were extracted from the electronic medical record and compared between survivors and non-survivors. Univariate and multivariate logistic regression were employed to identify the prognostic markers associated with mortality in patients with A. Fib/Flutter Results The total number of confirmed COVID-19 patients during the study period was 350; 37 of them had existing or new onset A. Fib/Flutter. Twenty one (57%) expired, and 16 (43%) were discharged alive. The median age was 72 years old, ranged from 19 to 100 years old. Comorbidities were present in 33 (89%) patients, with hypertension (82%) being the most common, followed by diabetes (46%) and coronary artery disease (30%). New onset of atrial fibrillation was identified in 23 patients (70%), of whom 13 (57%) expired; 29 patients (78%) presented with atrial fibrillation with rapid ventricular response, and 2 patients (5%) with atrial flutter. Mechanical ventilation was required for 8 patients, of whom 6 expired. In univariate analysis, we found a significant difference in baseline ferritin (p=0.04), LDH (p=0.02), neutrophil-lymphocyte ratio (NLR) (p=0.05), neutrophil-monocyte ratio (NMR) (p=0.03) and platelet (p=0.015) between survivors and non-survivors. With multivariable logistic regression analysis, the only value that had an odds of survival was a low NLR (odds ratio 0.74; 95% confidence interval 0.53–0.93). Conclusion This retrospective cohort study of hospitalized patients with COVID-19 demonstrated an association of increase NLR as risk factors for death in COVID-19 patients with A. Fib/Flutter. A high NLR has been associated with increased incidence, severity and risk for stroke in atrial fibrillation patients but to our knowledge, we are first to demonstrate the utilization in mortality predictions in COVID-19 patients with A.

Abstract Objective Spreading depolarizations (SD) are characterized by breakdown of transmembrane ion gradients and excitotoxicity. Experimentally, N-methyl-d-aspartate receptor (NMDAR) antagonists block a majority of SDs. In many hospitals, the NMDAR antagonist s-ketamine and the GABAA agonist midazolam represent the current second-line combination treatment to sedate patients with devastating cerebral injuries. A pressing clinical question is whether this option should become first-line in sedation-requiring individuals in whom SDs are detected, yet the s-ketamine dose necessary to adequately inhibit SDs is unknown. Moreover, use-dependent tolerance could be a problem for SD inhibition in the clinic. Methods We performed a retrospective cohort study of 66 patients with aneurysmal subarachnoid hemorrhage (aSAH) from a prospectively collected database. Thirty-three of 66 patients received s-ketamine during electrocorticographic neuromonitoring of SDs in neurointensive care. The decision to give s-ketamine was dependent on the need for stronger sedation, so it was expected that patients receiving s-ketamine would have a worse clinical outcome. Results S-ketamine application started 4.2 ± 3.5 days after aSAH. The mean dose was 2.8 ± 1.4 mg/kg body weight (BW)/h and thus higher than the dose recommended for sedation. First, patients were divided according to whether they received s-ketamine at any time or not. No significant difference in SD counts was found between groups (negative binomial model using the SD count per patient as outcome variable, p = 0.288). This most likely resulted from the fact that 368 SDs had already occurred in the s-ketamine group before s-ketamine was given. However, in patients receiving s-ketamine, we found a significant decrease in SD incidence when s-ketamine was started (Poisson model with a random intercept for patient, coefficient − 1.83 (95% confidence intervals − 2.17; − 1.50), p < 0.001; logistic regression model, odds ratio (OR) 0.13 (0.08; 0.19), p < 0.001). Thereafter, data was further divided into low-dose (0.1–2.0 mg/kg BW/h) and high-dose (2.1–7.0 mg/kg/h) segments. High-dose s-ketamine resulted in further significant decrease in SD incidence (Poisson model, − 1.10 (− 1.71; − 0.49), p < 0.001; logistic regression model, OR 0.33 (0.17; 0.63), p < 0.001). There was little evidence of SD tolerance to long-term s-ketamine sedation through 5 days. Conclusions These results provide a foundation for a multicenter, neuromonitoring-guided, proof-of-concept trial of ketamine and midazolam as a first-line sedative regime.

Limited Information

There is limited information regarding the severity of COVID-19 in immunocompromized patients. We conducted a retrospective cohort study considering the period from 1 March 2020 to 31 December 2020 to determine whether previously existing lymphopenia increases the risk of hospitalization and death after SARS-CoV-2 infection in the general population. The laboratory and hospital discharge databases of the Azienda Sanitaria Universitaria Friuli Centrale were used, and 5415 subjects infected with SARS-CoV-2 and with at least one recent absolute lymphocyte count determination before SARS-CoV-2 positivity were included. In total, 817 (15.1%) patients had severe COVID-19. Patients developing severe COVID-19 were more frequently males (44.9% of the severe COVID-19 group vs. 41.5% in the non-severe COVID-19 group; p < 0.0001) and were older (73.2 ± 13.8 vs. 58.4 ± 20.3 years; p < 0.0001). Furthermore, 29.9% of the lymphopenic patients developed severe COVID-19 vs. 14.5% of the non-lymphopenic patients (p < 0.0001). In a logistic regression model, female sex remained a protective factor (OR = 0.514, 95%CI 0.438–0.602, p < 0.0001), while age and lymphopenia remained risk factors for severe COVID-19 (OR = 1.047, 95%CI 1.042–1.053, p < 0.0001 for each additional year of age; OR = 1.715, 95%CI 1.239–2.347, p = 0.0011 for lymphopenia). This provides further information to stratify the risk of COVID-19 severity, which may be an important element in the management of immunosuppressive therapies.

Abstract Background: Blood urea nitrogen (BUN) and creatinine (SCr) are associated with gestational diabetes mellitus (GDM). However, there were limited data in the literature on the influence of BUN and SCr on maternal and fetal outcomes of pregnancy. We aimed to examine the association of BUN and SCr levels during gestation with the risk of selected adverse pregnancy outcomes.Methods: This retrospective cohort study included 1606 singleton mothers aged 22-44 years. Both BUN and SCr levels were collected and measured during the second (16-18th week), third (28-30th week) trimesters of gestation respectively and followed up pregnancy outcomes. Statistical analysis was used multivariate logistic regression. Results: In the multivariate adjusted logistic regression model, the highest level of SCr in the second trimester increased the risk of PROM by 45% (95% CI, 1.01-2.09). In the third trimester of gestation, compared with those in the lowest quartile, BUN levels in the highest quartile decreased the risk of macrosomia and LGA by 60%(95% CI, 0.20-0.78), 66%(95% CI, 0.21,0.55) , respectively, and increased the risk of SGA by 137%(1.06, 5.31), 186%(1.29,6.34) in the third and fourth quartiles, respectively. The adjusted OR (95%CI) for macrosomia in the fourth quartile was 0.46 (0.24, 0.87), for SGA in the third quartiles was 2.36 (1.10, 5.10), and for LGA in the fourth quartile was 0.61 (0.41,0.91) compared with those in the first quartile of SCr levels. The elevated changes of BUN (> 0.64mmol/L) was the risk factor of SGA (OR: 2.11, 95%CI: 1.03,4.32).Conclusion: Higher BUN and SCr levels during the 28-30th week of gestation even those towards the upper limit of the normal range can act as a warning sign of the impending SGA. Elevated changes of BUN and SCr during pregnancy also associated with the lower birth weight.
