Identification of lateralized cognitive profiles in surgical and nonsurgical pediatric epilepsy patients using the Cognitive Lateralization Rating Index.

Risk of Recurrence of Venous Thromboembolism After Major Surgery for Cancer,

Selective digestive decontamination (SDD) and selective oropharyngeal decontamination (SOD) are effective in improving survival in patients under intensive care. In this study possible differential effects in surgical and non-surgical patients were investigated. This was a post hoc subgroup analysis of data from a cluster-randomized multicentre trial comparing three groups (SDD, SOD or standard care) to quantify effects among surgical and non-surgical patients. The primary study outcome was 28-day mortality rate. Duration of mechanical ventilation, duration of intensive care unit (ICU) and hospital length of stay, and bacteraemia rates were secondary outcomes. The subgroup analyses included a total of 2762 surgical and 3165 non-surgical patients. Compared with standard care, adjusted odds ratios (ORs) for mortality were comparable in SDD-treated surgical and non-surgical patients: 0·86 (95 per cent confidence interval 0·69 to 1·09; P = 0·220) and 0·85 (0·70 to 1·03; P = 0·095) respectively. However, duration of mechanical ventilation, ICU stay and hospital stay were significantly reduced in surgical patients who had SDD. SOD did not reduce mortality compared with standard treatment in surgical patients (adjusted OR 0·97, 0·77 to 1·22; P = 0·801); in non-surgical patients it reduced mortality (adjusted OR 0·77, 0·63 to 0·94; P = 0·009) by 16·6 per cent, representing an absolute mortality reduction of 5·5 per cent with number needed to treat of 18. Subgroup analysis found similar effects of SDD in reducing mortality in surgical and non-surgical ICU patients, whereas SOD reduced mortality only in non-surgical patients. The hypothesis-generating findings mandate investigation into mechanisms between different ICU populations.

PET with 18F-FDG has been used for presurgical localization of epileptogenic foci; however, in nonsurgical patients, the correlation between cerebral glucose metabolism and clinical severity has not been fully understood. The aim of this study was to evaluate the glucose metabolic profile using 18F-FDG PET/CT imaging in patients with epilepsy. Methods: One hundred pediatric epilepsy patients who underwent 18F-FDG PET/CT, MRI, and electroencephalography examinations were included. Fifteen age-matched controls were also included. 18F-FDG PET images were analyzed by visual assessment combined with statistical parametric mapping (SPM) analysis. The absolute asymmetry index (|AI|) was calculated in patients with regional abnormal glucose metabolism. Results: Visual assessment combined with SPM analysis of 18F-FDG PET images detected more patients with abnormal glucose metabolism than visual assessment only. The |AI| significantly positively correlated with seizure frequency (P < 0.01) but negatively correlated with the time since last seizure (P < 0.01) in patients with abnormal glucose metabolism. The only significant contributing variable to the |AI| was the time since last seizure, in patients both with hypometabolism (P = 0.001) and with hypermetabolism (P = 0.005). For patients with either hypometabolism (P < 0.01) or hypermetabolism (P = 0.209), higher |AI| values were found in those with drug resistance than with seizure remission. In the post-1-y follow-up PET studies, a significant change of |AI| (%) was found in patients with clinical improvement compared with those with persistence or progression (P < 0.01). Conclusion:18F-FDG PET imaging with visual assessment combined with SPM analysis could provide cerebral glucose metabolic profiles in nonsurgical epilepsy patients. |AI| might be used for evaluation of clinical severity and progress in these patients. Patients with a prolonged period of seizure freedom may have more subtle (or no) metabolic abnormalities on PET. The clinical value of PET might be enhanced by timing the scan closer to clinical seizures.

Bariatric surgical procedures have been associated with increased risk of unhealthy alcohol use, but no previous research has evaluated the long-term alcohol-related risks after laparoscopic sleeve gastrectomy (LSG), currently the most used bariatric procedure. No US-based study has compared long-term alcohol-related outcomes between patients who have undergone Roux-en-Y gastric bypass (RYGB) and those who have not. To evaluate the changes over time in alcohol use and unhealthy alcohol use from 2 years before to 8 years after a bariatric surgical procedure among individuals with or without preoperative unhealthy alcohol use. This retrospective cohort study analyzed electronic health record (EHR) data on military veterans who underwent a bariatric surgical procedure at any of the bariatric centers in the US Department of Veterans Affairs (VA) health system between October 1, 2008, and September 30, 2016. Surgical patients without unhealthy alcohol use at baseline were matched using sequential stratification to nonsurgical control patients without unhealthy alcohol use at baseline, and surgical patients with unhealthy alcohol use at baseline were matched to nonsurgical patients with unhealthy alcohol use at baseline. Data were analyzed in February 2020. LSG (n = 1684) and RYGB (n = 924). Mean alcohol use, unhealthy alcohol use, and no alcohol use were estimated using scores from the validated 3-item Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), which had been documented in the VA EHR. Alcohol outcomes were estimated with mixed-effects models. A total of 2608 surgical patients were included in the final cohort (1964 male [75.3%] and 644 female [24.7%] veterans. Mean (SD) age of surgical patients was 53.0 (9.9) years and 53.6 (9.9) years for the matched nonsurgical patients. Among patients without baseline unhealthy alcohol use, 1539 patients who underwent an LSG were matched to 14 555 nonsurgical control patients and 854 patients who underwent an RYGB were matched to 8038 nonsurgical control patients. In patients without baseline unhealthy alcohol use, the mean AUDIT-C scores and the probability of unhealthy alcohol use both increased significantly 3 to 8 years after an LSG or an RYGB, compared with control patients. Eight years after an LSG, the probability of unhealthy alcohol use was higher in surgical vs control patients (7.9% [95% CI, 6.4-9.5] vs 4.5% [95% CI, 4.1-4.9]; difference, 3.4% [95% CI, 1.8-5.0])). Similarly, 8 years after an RYGB, the probability of unhealthy alcohol use was higher in surgical vs control patients (9.2% [95% CI, 8.0-10.3] vs 4.4% [95% CI, 4.1-4.6]; difference, 4.8% [95% CI, 3.6-5.9]). The probability of no alcohol use also decreased significantly 5 to 8 years after both procedures for surgical vs control patients. Among patients with unhealthy alcohol use at baseline, prevalence of unhealthy alcohol use was higher for patients who underwent an RYGB than matched controls. In this multi-site cohort study of predominantly male patients, among those who did not have unhealthy alcohol use in the 2 years before bariatric surgery, the probability of developing unhealthy alcohol use increased significantly 3-8 years after bariatric procedures compared with matched controls during follow-up.

INTRODUCTION: Temporal lobe epilepsy with encephalocele (TLEE) is a lesional epilepsy increasingly recognized as underdiagnosed. Here we report our experience with TLEE-associated epilepsy managed with both traditional ATL with AH compared to a targeted lesionectomy of the encephalocele. METHODS: We used a prospectively maintained database of surgical epilepsy patients to identify all patients with TLEE-associated epilepsy managed over a 13-year interval using ATL with AH, ATL only, or a targeted encephalocele-only lesionectomy. Details regarding epilepsy, neuropsychology, management, complications, and outcomes at the last follow-up were compiled. RESULTS: 793 surgical epilepsy patients were evaluated, with 56 (7.1%) demonstrating TLEE. The average age of epilepsy onset was 31.7 years (range 2-57); the age at the time of surgery was 38.3 years (range 15-69). Twenty-one patients (37.5%) were managed with ATL with AH, 20 (35.7%) with temporal pole resection without AH, and 15 (26.7%) with targeted lesionectomy/LITT of the temporal encephalocele. Forty-seven patients (84%) had good surgical epilepsy outcomes with no significant difference in modality. Targeted lesionectomy demonstrated significantly greater language preservation (p = 0.046) and verbal memory (p = 0.038) when compared to more extensive surgical resections. CONCLUSIONS: TLEE is an overlooked and underreported etiology of epilepsy. In select cases, good surgical epilepsy outcomes can be achieved with targeted lesionectomy of the encephalocele when the epilepsy network is not widespread.

Link of Video Abstract: https://youtu.be/2wcFE-82J2s Background: Critically ill patients in intensive care have a higher predisposition to acquire bacterial infections in the bloodstream. Research on bacterial profiles and blood culture sensitivity patterns in bacteremia patients can provide information for the basis of diagnosis, approaches, and treatment strategies in patients. To better understand the microbial profile and pattern of antimicrobial sensitivity of blood specimen isolate among non-COVID patients in the intensive care unit, we evaluated data from medical records that included blood cultures for all participants in the intensive care unit from January 2019 to April 2022. Method: A retrospective observational study with a cross-sectional approach was conducted in the Clinical Microbiology Department and Medical Record Unit at Dr. Soetomo Hospital. Data on surgical and non-surgical noncovid patients with bacteremia in intensive care unit patients was collected from January 2019 to April 2022. The Sample was taken with a consecutive sampling technique. Results: There were 140 isolates with positive blood culture results. The most common bacteria are coagulase-negative Staphylococcus 22 (15.7%), Acinetobacter baumanii 25 (17.9%), and Pseudomonas aeruginosa 13 (4.9%) in surgical and non-surgical patients. Sensitivity to Gram-positive bacteria in surgical and non-surgical patients before the pandemic linezolid 75% and vancomycin 58,3%. During pandemic linezolid at 76.9% and vancomycin at 69.2%. Sensitivity of Gram-negative bacteria in surgical patients before the pandemic was imipenem 57.1%, meropenem 57.1%, and amikacin 47.6%. During the pandemic, amikacin 73.5%, meropenem 55.1%, and imipenem 53.1%. Non-surgical patients before the pandemic gram negative sensitivity to meropenem was 100%, ceftazidime 66.7%. During the pandemic, amikacin 59.1%, and cotrimoxazole 45.5%. Conclusion: There was no difference in the surgical and non-surgical bacterial profiles before the pandemic and during the pandemic.

Survival of surgical and non-surgical older patients with non-metastatic colorectal cancer: A population-based study in the Netherlands

Background/Purpose Historically, decompressive laparotomy and open abdomen for abdominal compartment syndrome has contraindicated Extracorporeal Membrane Oxygenation (ECMO) due to seemingly high risk of bleeding and infection. The literature shows few examples of this treatment, and the existing studies are inconclusive. The purpose of this study was to review the series at Riley Hospital for Children and evaluate the effectiveness of ECMO treatment for patients undergoing decompressive laparotomy with open abdomen to recommend future care guidelines. Methods We reviewed all pediatric (30 days to 18 years) patients treated with ECMO concurrently with decompressive laparotomy and open abdomen at Riley Hospital for Children from 2000-2019. We compared these patients with non-surgical pediatric patients supported with ECMO for respiratory failure at Riley Hospital for Children during the same period. Demographics, ECMO data, and outcomes were assessed. We performed t-test, ROC, and chi-square analyses. We defined significance as p=0.05. Results 5 of 82 pediatric respiratory ECMO patients were treated with decompressive laparotomy and open abdomen. Survival among the surgical group was 60%, compared to 57% in the non-surgical group (p=0.9). Surgical patients had a similar incidence of bleeding complications (40%) compared to non-surgical patients (55.8%), p=0.486. Surgical patients had a significantly higher VIS (3126 vs 19.2, p=0.004), PaO2/FiO2 ratio (279.0 vs 72.9, p=0.031), and pump flow rate at 24hrs (112mL/kg/min vs 88.1mL/kg/min, p=0.045) than non-surgical patients, while receiving a similar volume of PRBCs (p=0.581) and requiring ECMO treatment for a similar amount of time (p=0.511). Conclusion/Potential Impact ECMO support in patients with decompressive laparotomy and open abdomen was associated with similar survival and bleeding complications compared to non-surgical ECMO patients. ECMO should be offered to or continued in eligible patients with abdominal catastrophe, as it is effective in supporting organ function while not significantly increasing the risk for complications.

For the spectroscopic assessment of brain disorders that require large-volume coverage, the requirements of RF performance and field homogeneity are high. For epilepsy, this is also challenging given the inter-patient variation in location, severity and subtlety of anatomical identification and its tendency to involve the temporal region. We apply a targeted method to examine the utility of large-volume MR spectroscopic imaging (MRSI) in surgical epilepsy patients, implementing a two-step acquisition, comprised of a 3D acquisition to cover the fronto-parietal regions, and a contiguous parallel two-slice Hadamard-encoded acquisition to cover the temporal-occipital region, both with TR /TE = 2000/40 ms and matched acquisition times. With restricted (static, first/second-order) B0 shimming in their respective regions, the Cramér-Rao lower bounds for creatine from the temporal lobe two-slice Hadamard and frontal-parietal 3D acquisition are 8.1 ± 2.2% and 6.3 ± 1.9% respectively. The datasets are combined to provide a total 60 mm axial coverage over the frontal, parietal and superior temporal to middle temporal-occipital regions. We applied these acquisitions at a nominal 400 mm3 voxel resolution in n = 27 pre-surgical epilepsy patients and n = 20 controls. In controls, 86.6 ± 3.2% voxels with at least 50% tissue (white + gray matter, excluding CSF) survived spectral quality inclusion criteria. Since all patients were clinically followed for at least 1 year after surgery, seizure frequency outcome was available for all. The MRSI measurements of the total fractional metabolic dysfunction (characterized by the Cr/NAA metric) in FreeSurfer MRI gray matter segmented regions, in the patients compared with the controls, exhibited a significant Spearman correlation with post-surgical outcome. This finding suggests that a larger burden of metabolic dysfunction is seen in patients with poorer post-surgical seizure control.

Betweenness centrality of intracranial electroencephalography networks and surgical epilepsy outcome

Being "at risk of malnutrition", which includes both malnutrition and the risk to be so, is associated with increased morbidity and mortality in both surgical and non-surgical patients. Several strategies and guidelines have been introduced to prevent and treat this, but the effects are scarcely investigated. This study aims to evaluate the long-term effects of these efforts by examining trends concerning: 1) the prevalence of patients«at risk of malnutrition» and 2) the use of nutritional support and diagnostic coding related to malnutrition over an 11-year period in a large university hospital. Moreover, we wanted to investigate if there was a difference in trends between surgical and non-surgical patients. From 2008 to 2018, Haukeland University Hospital, Norway, conducted 34 point-prevalence surveys to investigate the prevalence of patients«at risk of malnutrition», as defined by Nutritional Risk Screening 2002, and the use of nutritional support at the hospital. Diagnostic coding included ICD-10 codes related to malnutrition (E43, E44 and E46) at hospital discharge, which were extracted from the electronic patient journal. Trend analysis by calendar year was investigated using logistic regression models with and without adjustment for age (continuous), gender (male/female) and Charlson Comorbidity Index (none, mild, moderate or severe). The number of patients included in the study was 18933, where 52.1% were male and the median (25th, 75th percentile) age was 65 (51, 76) years. Of these, 5121 (27%) patients were identified to be «at risk of malnutrition». Fewer surgical patients (21.2%) were «at risk of malnutrition», as compared to non-surgical patients (30.9%) (p<0.001). Adjusted trend analysis did not identify any change in the prevalence of patients«at risk of malnutrition» from 2008 to 2018. The percentage of patients«at risk of malnutrition»who received nutritional support increased from 61.6% in 2008 to 71.9% in 2018 (p<0.001), with a range from 55.6 to 74.8%. This trend was seen for both surgical and non-surgical patients (p<0.001 for both). Similarly, dietitians were more involved in the patients' treatment (range: 3.8-16.7%), and there was increased use of ICD-10 codes related to malnutrition during the study period (range: 13.0-41.8%) (p<0.001). These trends were seen for both surgical patients and non-surgical patients (p<0.001), despite use being less common for surgical patients, as compared to non-surgical patients (p<0.001). This large hospital study shows no apparent change in the prevalence of patients«at risk of malnutrition» from 2008 to 2018. However, more patients«at risk of malnutrition», both surgical and non-surgical, received nutritional support, treatment from a dietitian and a related ICD-10 code over the study period, indicating improved nutritional routines as a result of the implementation of nutritional guidelines and strategies.

Obesity rates in patients with end-stage kidney disease are rising, contribute to excess morbidity, and limit access to kidney transplant. Despite this, there continues to be controversy around the use of bariatric surgery in this patient population. To determine whether bariatric surgery is associated with improvement in long-term survival among patients with obesity and end-stage kidney disease. Retrospective cohort study and secondary analysis of previously collected data from the United States Renal Data System registry (2006-2015). We used Cox proportional hazards analysis to evaluate differences in outcomes for patients receiving bariatric surgery (n = 1597) compared with a matched cohort of nonsurgical patients (n = 4750) receiving usual care. Data were analyzed between September 3, 2019, and November 13, 2019. Receipt of bariatric surgery. All-cause mortality at 5 years. Secondary outcomes included disease-specific mortality and incidence of kidney transplant. Surgical and nonsurgical control patients had similar age, demographics, and comorbid disease burden. The mean (SD) age was 49.8 (11.2) years for surgical patients vs 51.7 (11.1) years for nonsurgical patients. Six hundred fifteen surgical patients (38.5%) were black vs 1833 nonsurgical patients (38.6%). Surgery was associated with lower all-cause mortality at 5 years compared with usual care (cumulative incidence, 25.6% vs 39.8%; hazard ratio, 0.69, 95% CI, 0.60-0.78). This was driven by lower mortality from cardiovascular causes at 5 years for patients undergoing bariatric surgery compared with nonsurgical control patients (cumulative incidence, 8.4% vs 17.2%; hazard ratio, 0.51; 95% CI, 0.41-0.65). Bariatric surgery was also associated with an increase in kidney transplant at 5 years (cumulative incidence, 33.0% vs 20.4%; hazard ratio, 1.82; 95% CI, 1.58-2.09). However, at 1 year, bariatric surgery was associated with higher all-cause mortality compared with usual care (cumulative incidence, 8.6% vs 7.7%; hazard ratio, 1.45; 95% CI, 1.13-1.85). Among patients with obesity and end-stage kidney disease, bariatric surgery was associated with lower all-cause mortality compared with usual care. Bariatric surgery was also associated with an increase in kidney transplant. Bariatric surgery may warrant further consideration in the treatment of patients with obesity and end-stage kidney disease.

ABSTRACTWe conducted this systematic review to clarify the clinical characteristics, complications, and outcomes of surgical and non-surgical patients with fragility fracture of the pelvis (FFP). We searched PubMed, Google Scholar, Cochrane Library, Web of Science, and MEDLINE for English language articles on FFP. We calculated pooled odds ratios (ORs) or mean differences (MDs) of surgical patients in comparison to non-surgical patients for clinical characteristics (Rommens FFP classification, age, sex, dementia, osteoporosis, diabetes mellitus, pulmonary disease, cardiovascular disease, and malignancy), complications (pneumonia, urinary tract infection, cardiac event, thrombosis, pulmonary embolism, pressure ulcer, multiple organ failure, anemia caused by surgical bleeding, and surgical site infection), and outcomes (hospital mortality and one-year mortality). Five studies involving 1,090 patients with FFP (surgical patients, n = 432; non-surgical patients, n = 658) were included. FFP type III and IV (OR = 8.44; 95% confidence interval [CI] 5.99 to 11.88; p<0.00001), a younger age (MD = –3.29; 95% CI –3.83 to –2.75; p<0.00001), the absence of dementia (OR = 0.36; 95% CI 0.23 to 0.57; p<0.0001), and the presence of osteoporosis (OR = 1.74; 95% CI 1.29 to 2.35; p = 0.0003) were significantly associated with the surgical patients. Urinary tract infection (OR = 2.06; 95% CI 1.37 to 3.10; p = 0.0005), anemia caused by surgical bleeding (OR = 4.55; 95% CI 1.95 to 10.62; p = 0.0005), and surgical site infection (OR = 16.74; 95% CI 3.05 to 91.87; p = 0.001) were significantly associated with the surgical patients. There were no significant differences in the outcomes between the surgical and non-surgical patients. Our findings may help to further understand the treatment strategy for FFP and improve clinical outcomes.

Methicillin-Resistant Staphylococcus aureus (MRSA) in the hospital is found mainly in surgical patients, which increases morbidity and mortality. Currently, vancomycin is the drug of choice for the treatment of MRSA infections. The increasing use of vancomycin and its inappropriate administration may increase the resistance of S. aureus to vancomycin. This study aimed to describe the distribution of MRSA and types of antibiotics that are still sensitive to MRSA in surgical and non-surgical patients. This cross-sectional, observational, retrospective descriptive study was conducted at the Microbiology Laboratory, Dr. Hasan Sadikin General Hospital, in 2019 using secondary data on the results of culture examination and antibiotic susceptibility of positive S. aureus culture isolates from all types of isolates from surgical and non-surgical patients. All specimens were cultured in appropriate media. Identification of S. aureus was performed by Gram staining to identify bacterial morphology, and automatic tools. Antibiotic susceptibility test was performed using an automatic machine. Seventy-five isolates (17%) were identified to be MRSA with 46 (53%) of them retrieved from surgical patients. Most of the MRSA isolates came from pus and were mostly due to skin infections. Antibiotic susceptibility results showed two Vancomycin-Resistant Staphylococcus aureus (VRSA) isolates from surgical patients. The positive culture of the MRSA and VRSA was dominated by surgical patients with pus coming from surgical wound infection, burn, and other skin infection as the most common sources. Thus, the proportion of MRSA isolates in the hospital in 2019 is 17% and two VRSA isolates are identified in the same year. The surgical ward was the primary origin of most MRSA isolates. Further studies are necessary to identify the MRSA incidence rate, evaluation and periodic monitoring of antibiotic use, and active surveillance in the surgical patient rooms.

Severe sepsis, defined as a systemic inflammatory response to infection associated with acute organ dysfunction, is common among surgical patients and is a major cause of morbidity and mortality. Severe sepsis has been associated with changes in inflammatory and hemostatic biomarkers. In patients undergoing surgical procedures there may be additional stimulation of cytokine release and activation of the coagulation system. The purpose of this study was to characterize the baseline differences in biomarkers between surgical and non-surgical patients. In addition, we assessed the dynamic changes in biomarkers and coagulation parameters in surgical patients with severe sepsis enrolled in PROWESS and treated with placebo or drotrecogin alfa (activated). A blinded PROWESS surgical evaluation committee (SEC) verified patients as having undergone a relevant operative procedure within 30 days of enrollment for inclusion in the surgical cohort of PROWESS. At baseline and on study days 1-7, biomarkers and coagulation parameters available for analysis were D-dimer, interleukin-6 (IL-6), protein C activity, protein S activity, anti-thrombin III (ATIII), activated partial thromboplastin time (aPTT), and prothrombin time (PT). Platelet count was determined at baseline only. Baseline values were compared between SEC-defined surgical and all other non-surgical patients, and between pre- and post-operative surgical patients from the PROWESS trial. Changes from baseline were compared between drotrecogin alfa (activated)-treated and placebo-treated surgical patients. Statistical analyses were performed using ANOVA on the ranked values. The SEC verified 474 (28%) of the 1,690 PROWESS patients as surgical. Median D-dimer, IL-6, aPTT and PT values were significantly higher at baseline for surgical patients than non-surgical patients (p < 0.001). Surgical patients had significantly lower median protein C, protein S, and ATIII activity at baseline than non-surgical patients (p < 0.001). Surgical patients treated with drotrecogin alfa (activated) showed a significant decrease in D-dimer levels on study days 1-5 (p < 0.05), and a more rapid increase in Protein C levels on study days 1-4 (p < 0.05) compared to placebo. Surgical patients with severe sepsis appear to have a higher severity of illness at baseline as demonstrated by derangements in biomarkers and coagulation markers compared to non-surgical patients. Surgical patients treated with drotrecogin alfa (activated)showed reduced D-dimer concentrations and a more rapid increase in protein C concentrations during the infusion period.
