Cognitive dysfunction is a common disease in aging population. This study aims to compare the influence of different degrees of anemia on the cognitive function of patients undergo hysteromyoma surgery. Sixty-one patients aged 18–60 years who underwent uterine fibroid surgery in the Second Affiliated Hospital of Shantou University Medical College from March 2019 to December 2020 were selected for this study. Patients were divided into three groups: group normal (Group N, patients have no anemia), group of mild anemia (Group Mi, patients have mild anemia) and group of moderate anemia (Group Mo, patients had moderate anemia). Combined spinal and epidural anesthesia were administered. Cognitive function tests were performed 1 day before the surgery and repeated at the 5th and 30th days after surgery. Peripheral venous blood samples from patients were collected before the surgery, right after surgery and at the 24th and 72nd hours after surgery. The contents of S-100β, IL-6, TNF-α and IL-1β in serum samples were determined by ELISA. It was found that there were no significant differences in general characteristics of patients among Group N, Group Mi and Group Mo (p > 0.05). Nine patients developed postoperative cognitive dysfunction after surgery, and the incidence was 14.75% (9/61). The incidence of postoperative cognitive dysfunction (POCD) was 40% in Group Mo, which was higher than that in Group N and Group Mi. The difference was statistically significant (p < 0.05). Inflammatory factors in patients with POCD were higher in post-surgery than before-surgery (p < 0.05), while there was no statistical significance in the difference of inflammatory factors of patients without POCD before and after surgery (p > 0.05). Taken together, this study suggested that moderate anemia could be a risk factor of POCD in patients undergoing hysteromyoma surgeries. This study will help surgeons developing measures for preventing the occurrence of POCD.

OBJECTIVESurgical trauma is known to result in systemic inflammatory changes that can lead to postoperative cognitive dysfunction. In the present study, the authors compared the effects of an epidural anesthesia protocol to those of traditional anesthesia with regard to postoperative inflammatory changes, cellular immunity, and cognitive dysfunction.METHODSForty-eight patients, ages 45–60 years, underwent multilevel thoracolumbar decompression and fusion and were randomly assigned to one of two groups: group 1 (27 patients) had combined epidural and general anesthesia, followed by epidural analgesia for 48 hours after surgery, and group 2 (21 patients) had general anesthesia, followed by traditional opioid pain management after surgery. At multiple time points, data on pain control, cognitive function, cellular immunity, and inflammatory markers were collected.RESULTSGroup 1 patients demonstrated lower pain levels, less systemic inflammation, less cellular immune dysfunction, and less postoperative cognitive dysfunction than group 2 patients.CONCLUSIONSThe use of combined epidural and general anesthesia followed by postoperative epidural analgesia during the first 48 hours after multilevel thoracolumbar decompression and fusion surgery had a significant positive effect on pain management, cellular immune function, systemic inflammation, and postoperative cognitive function.Clinical trial registration no.: 115080510080 (http://rosrid.ru)

ObjectiveThis study aimed to explore the influence of coronary artery bypass grafting (CABG) on both postoperative cognitive dysfunction and quality of life (QoL) and the association between the two patient-related outcomes.MethodsIn a prospective, observational cohort study, patients with elective, isolated CABG were included. Cognitive function was assessed using the Cogstate computerised cognitive test battery preoperatively, 3 days and 6 months after surgery. QoL was measured preoperatively and at 6 months using the RAND-36 questionnaire including the Physical Component Score (PCS) and the Mental Component Score (MCS). Regression analysis, with adjustment for confounders, was used to evaluate the association between postoperative cognitive dysfunction and QoL.ResultsA total of 142 patients were included in the study. Evidence of persistent cognitive dysfunction was observed in 33% of patients after 6 months. At 6 months, the PCS had improved in 59% and decreased in 21% of patients, and the MCS increased in 49% and decreased in 29%. Postoperative cognitive changes were not associated with QoL scores.ConclusionsPostoperative cognitive dysfunction and decreased QoL are common 6 months after surgery, although cognitive function and QoL were found to have improved in many patients at 6 months of follow-up. Impaired cognitive function is not associated with impaired QoL at 6 months.Trial registration numberNCT03774342.

The aim of the present study was to evaluate the relationship between the oxidative status and the severity and type of anemia in dogs. A total of 70 dogs of various breeds, ages and of both sexes were enrolled in the study. Fifty dogs with anemia were classified according to the severity of anemia as mildly (n=18), moderately (n=18) or severely (n=14) anemic on the basis of the hematocrit (HCT) value. Anemia in the same dogs was also classified according to the type as regenerative (n=26) or non-regenerative (n=24) on the basis of the absolute reticulocyte count. Twenty dogs were used as healthy control. Total oxidant status (TOS), total antioxidant capacity (TAC) and malondialdehyde (MDA) values in plasma as well as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) activities in erythrocyte hemolysate were measured to evaluate the oxidative status. The plasma TOS value was increased in all anemic dogs, irrespective of the severity of anemia, whereas a significant increase in the TAC value and a significant decrease in erythrocyte GSH-Px activity were observed in mild and moderate anemia. Plasma TOS and TAC values were higher in dogs with both types of anemia when compared to the healthy group. A significant increase in plasma MDA concentration and a significant decrease in GSH-Px activity were observed in the non-regenerative anemia group. There were moderate negative correlations between HCT and TOS values in the mild anemia group and between HCT and erythrocyte GSH-Px activity in the regenerative anemia group. In conclusion, oxidative stress develops in dogs with anemia, and it is largely independent of the severity and type of anemia. These results suggest that further studies with different etiologies may also be useful for evaluating the efficacy of antioxidants administered at different doses and in different combinations to treat anemia in dogs.

Aim. The aim of the present study was to evaluate the relationship between iron deficiency anemia and small for gestational age (SGA) in early third trimester pregnancies. Methods. A total of 4800 pregnant women who met the inclusion criteria were analyzed retrospectively. We included pregnant women who had iron deficiency anemia between 26+0 and 30+0 weeks of gestation and delivered singletons between 37+0 and 41+6 weeks of gestation. Patients were divided into four groups according to anemia level: (1) hemoglobin (Hb) < 7 mg/dl (n = 80), (2) Hb 7–9.9 mg/dl (n = 320), (3) Hb 10–10.9 mg/dl (n = 1300), and (4) Hb > 11 mg/dl (n = 3100, control group). The primary outcome of this study was the presence of SGA. Results. The demographic and obstetric characteristics were similar among all the groups. Maternal age, BMI <30 kg/m2, nulliparity rates, and previous cesarean delivery rates were similar among groups. Ethnicity was significantly different in the severe and moderate anemia groups (<0.001). Mean fetal weight was 2900 ± 80 g in the severe anemia group, 3050 ± 100 g in the moderate anemia group, 3350 ± 310 g in the mild anemia group, and 3400 ± 310 g in the control group. Fetal weight was significantly lower in the severe and moderate anemia groups compared to the mild anemia and control groups (<0.001). The SGA rate was 18.7% in the severe anemia group, 12.1% in the moderate anemia group, 5.3% in the mild anemia group, and 4.9% in the control group. SGA was significantly higher in the severe and moderate anemia groups compared to the mild anemia and control groups (<0.001). Conclusion. The results of this study indicated that early third trimester severe and moderate iron deficiency anemia was associated with SGA. Iron deficiency anemia in pregnant women may lead to low birth weight.

Postoperative cognitive dysfunction increases mortality and morbidity in perioperative patients. Numerous studies have demonstrated that multiple surgery/anesthesia during the neurodevelopmental period affects cognitive function, whereas a single anesthesia/surgery rarely causes cognitive dysfunction in adults. However, whether adults who undergo multiple anesthesia/surgery over a short period will experience cognitive dysfunction remains unclear. In this study, central nervous system inflammation and changes in cholinergic markers were investigated in adult mice subjected to multiple laparotomy procedures over a short period of time. The results showed that despite the increased expression of IL-6 and TNF-α in the hippocampus after multiple operations and the activation of microglia, multiple anesthesia/surgery did not cause a decline in cognitive function in adult mice. There were no changes in the cholinergic markers after multiple anesthesia/surgery.

Abstract Postoperative cognitive dysfunction (POCD) affects a large number of post-surgery patients, especially for the elderly. However, the etiology of this neurocognitive disorder is largely unknown. Even if several studies have reported a small number of miRNAs as the essential modulatory factors in POCD, these findings are still rather limited. In this study, we used two miRNA microarray datasets to perform differential expression analyses of miRNAs in the hippocampus of POCD model mice. We found that nine miRNAs showed significant associations with POCD in both datasets. Among these miRNAs, mmu-miR-190a-3p was the most significant one. By performing weighted gene co-expression network analysis, we found 25 co-expression modules, of which mmu-miR-190a-3p was significantly anti-correlated with the red module. Moreover, in this red module, 314 genes were significantly enriched in four pathways such as axon guidance and calcium signaling pathway, which are well-documented to be associated with psychiatric disorders and brain development. Also, 169 of the 314 genes were highly correlated with mmu-miR-190a-3p, and four genes (Sphkap, Arhgef25, Tiam1, and Ntrk3) had putative binding sites at 3'-UTR of mmu-miR-190a-3p. Based on protein-protein network analysis, we detected that Tiam1 was a central gene regulated by the mmu-miR-190a-3p. Taken together, we conclude that mmu-miR-190a-3p is involved in the etiology of POCD and may serve as a novel predictive indicator for POCD.

Background. The issue of analysis of diagnostic criteria and adequate neuroprotective management of postsurgery cognitive dysfunction in abdominal oncosurgery, depending on the degree and structure of disorders, remains unresolved, determining its relevance. Purpose – assessing the postsurgery cognitive dysfunction in patients with neoplasms of the abdominal cavity and management of possible disorders with citicoline depending on the level of general cognitive deficit. Materials and methods. TThe study was conducted at the premises of departments for patients of surgical profile of Municipal Institution “Kharkov City Clinical Hospital of Ambulance and Emergency Care named after Professor O.I. Meshchaninov”. To achieve the aim of the study, 80 patients with abdominal neoplasms who underwent surgery under general anesthesia using propofol and fentanyl were examined. Results and discussion. Based on the comprehensive clinical study and anal- ysis of the mechanisms of formation of postsurgery cognitive dysfunction in patients of oncosurgical profile after surgery under general anesthesia, we suggested directions and schemes for managing postsurgery cognitive dysfunction by means of the developed clinical diagnostic criterion, which is essential in forming individual scheme of treating patients in postsurgery period. Conclusions. Based on the analysis of data on the state of cognitive function changes, comparing the postsurgery period with the preoperative state, a differentiated approach to intensive neuroprotective therapy of postoperative cognitive dysfunction was developed. The technique of intensive neuroprotective   therapy   of   postsurgery   cognitive   dysfunction in patients with abdominal neoplasms, undergoing surgery under general anesthesia, was suggested.

Objective: Postoperative cognitive dysfunction (POCD) can feature a wide spectrum of clinical symptoms, from asymptomatic to debilitating dementia, that lead to increased dependence, lower quality of life, morbidity, and mortality. Protein S100B is a direct marker for neuronal cell damage. We aimed to evaluate S100B as a biomarker for predicting POCD following open-heart surgery. Methods: This was an observational-analytic study to assess changes of the S100B level following open-heart surgery in Cipto Mangunkusumo Hospital, Jakarta. All subjects underwent cognitive function evaluations that consisted of six psychometric tests on the day prior to surgery and five days after surgery. Cognitive dysfunction was determined if there was a>20% cognitive score drop from baseline values in at least two tests. Blood samples for S100B were obtained (1) before the induction of anesthesia and (2) six hours after surgery. Samples were analyzed using enzyme-linked immunosorbent assay for S100B. All data were analyzed using SPSS 20. Results: Among the 55 subjects analyzed, 31 (56.4%) were found to have a decline in cognitive function. There were no differences in baseline characteristics, comorbidities, and perioperative data. Oxygen contents also did not show significant differences at any time. The S100B levels in all subjects increased. This increase was>1.5x higher in subjects with POCD compared to those without POCD (2.15[0.22–60.03] vs. 1.33[0.15–19.77] ng/ml, p = 0.16). However, this difference was not statistically significant. Conclusion: This study showed that serum S100B is higher in POCD patients and has the potential to be a biomarker for predicting POCD after open-heart surgery.

9070 Background: Cytokines have been associated with fatigue and cognitive dysfunction. Here we evaluated plasma cytokine levels in pts with colorectal cancer (CRC) and breast cancer (BC) who were free of evident disease, and in healthy volunteers. Methods: Serum levels of 10 cytokines were measured using a LiquiChip assay on 251 subjects. CRC pts (n=136, ages 23–75) were evaluated at baseline (mean 8 weeks post-surgery [n=107] or before surgery [n=29]), with repeat measures at 6 months (56 post chemotherapy [CT], 14 without CT) and 12 months (32 post CT, 7 without CT). BC pts (n=51, ages 29–60) were within 5 years of diagnosis (33 after adjuvant CT). Healthy volunteers (n=64) had ages 20–62. Cancer pts completed questionnaires for fatigue & QOL (FACT-F), anxiety/depression (GHQ), and perceived cognitive function (FACT-COG); they had neuropsychological assessment. Results: Cytokines were elevated in all cancer groups compared to healthy controls (p-values <0.001; selected data in table ). Values were highest after surgery but remained significantly higher than healthy controls at 6–60 months after diagnosis, with a trend to being higher in cancer patients who had not received CT. There was a trend to elevated cytokines being associated with greater fatigue and cognitive impairment in both CRC and BC, but no association with QOL or anxiety & depression. Conclusions: Cytokine levels were elevated in all cancer groups compared to healthy volunteers and remained elevated up to 5 years post diagnosis; they may be associated with cognitive dysfunction and fatigue.
