Cardiac surgery causes a series of disturbances in human physiology. The correction of systemic hemodynamic variables is frequently ineffective in improving microcirculatory perfusion and delivering oxygen to the tissues. We present the case of a 52-year-old male submitted to mitral valve replacement (metallic valve) and subaortic membrane resection. Sublingual microcirculatory density and perfusion were evaluated using a handheld CytoCam camera before surgery and in the early postoperative period. In this case, systemic hemodynamic variables were compromised despite an actual improvement in the microcirculatory parameters in comparison to the preoperative evaluation, possibly due to the correction of the structural cardiac defects.

UNASSIGNED: surgical site infection is associated with longer postoperative hospital stays. We explored factors associated with longer postoperative hospital stays among patients in the surgical ward of a primary rural hospital in Ethiopia, where laboratory facilities for microbiological confirmation of surgical site infections were not available.
UNASSIGNED: an observational study was performed for patients ≥ 18 years of age who underwent elective or emergency surgery from 22nd June 2017 to 19th July 2018. Data were taken from paper-based medical records and patient interviews. The primary outcome was postoperative length of hospital stay. Data were analyzed by multivariable linear regression using Stata software, version 13.
UNASSIGNED: seventy-five patients were enrolled, sociodemographic data was obtained from 14 of these patients by interview, and 44 patients had complete outcome and covariate data and were included in regression analysis. Median length of preoperative hospital stay was 3.0 (interquartile range 2.0) days. Postoperative length of hospital stay was longer by 3.8 days (95% confidence interval (CI) 1.05-6.55; p=0.008), 4.7 days (95% CI 1.64-7.66; p=0.004), and 5.9 days (95% CI 2.70-9.02; p=0.001), for patients 35-54 years, 55-64 years and the 65+ years respectively, compared to patients who were 18-34 years of age. Patients who received preoperative antibiotics stayed 5.3 days longer (95% CI 1.67-8.87; p=0.005) compared to those who were not given preoperative antibiotics.
UNASSIGNED: age and improper use of preoperative antibiotics compound the risk for postoperative length of stay. Infection prevention protocols, including staff training, and surveillance for surgical site infections are critical for improving hospital outcomes.

BACKGROUND: The effect of pump flow type on perfusion in coronary surgery using cardiopulmonary bypass (CPB) is discussed. We aimed to evaluate the effect of pump flow type on cognitive functions with neurocognitive function tests.
METHODS: One hundred patients who underwent isolated coronary artery bypass surgery between November 2020 and July 2021 were divided into two equa groups. Groups were formed according to pump flow type pulsatile (Group 1) and non-pulsatile (Group 2). Clock drawing test (CDT) and standardized mini mental test (SMMT) were performed on the patients in both groups in the preoperative period, on the 1st preoperative day, and on the day before discharge. Neurocognitive effects were compared with all follow-up parameters.
RESULTS: There was no difference between the groups in terms of demographic data and in terms of neurocognitive tests performed before the operation. SMMT on postoperative day 1 (Group I: 27.64 ± 1.05; Group II: 24.44 ± 1.64; P=0.001) and CDT (Group I: 5.4 ± 0.54; Group II: 4 .66 ± 0.52; P=0.001), and SMMT on the day before discharge (Group I: 27.92 ± 1.16; Group II: 24.66 ± 1.22; P=0.001) and CDT (Group I: 5 It was calculated as .66 ± 0.48; Group II: 5.44 ± 0.5; P=0.001). The duration of intensive care and hospitalization were higher in the non-pulsatile group.
CONCLUSIONS: We think that the type of pump flow used in coronary artery bypass surgery using CPB is effective in terms of neurocognitive functions and that pulsatile flow makes positive contributions to this issue.

OBJECTIVE: Evaluation of the impact of patients\' participation on postoperative recovery and satisfaction who underwent the Percutaneous Endoscopic Interlaminar Discectomy(PEID).
METHODS: We collected data from sixty-nine patients who underwent PEID surgery at Chuzhou Chinese and Western Medicine Hospital between January 2020 and December 2022. All patients had L5/S1 lumbar disc herniation and met the inclusion and exclusion criteria. The patients were divided into two groups: non-communication group (n = 33) and communication group (n = 36). The division was made based on whether the patients had preoperative surgical video viewing and intraoperative communication. We compared the baseline data, surgical time, VAS score, lumbar JOA score, surgical complications, and patient satisfaction between the two groups.
RESULTS: The communication group showed better pain control and functional recovery in the early postoperative period. The communication group had better VAS scores on the first day and month after surgery, as well as JOA scores on the first week and month after surgery, with statistically significant differences (P < 0.05). There was no significant difference in hospital stay, VAS score, JOA score, and postoperative complications between the two groups of patients at 3 and 6 months after surgery. The communication group had higher patient satisfaction (P < 0.05).
CONCLUSIONS: Preoperative surgical video viewing and intraoperative communication by PEID patients can alleviate pain, accelerate functional recovery, improve symptoms, and increase patients\' satisfaction. We need to do more work to develop this new model.

BACKGROUND: Tacrolimus is a potent calcineurin inhibitor (CNI) that is principally used as a first-line immunosuppressant for the prophylaxis of allograft rejection in liver transplantation (LT) patients. In clinical practice, prescribing the optimal tacrolimus dosage is complicated by its narrow therapeutic index and high pharmacokinetic variability. Thus, performing therapeutic drug monitoring (TDM) of only tacrolimus may not provide optimal drug levels. However, other influential clinical factors affecting tacrolimus levels, such as hemoglobin (Hb), hematocrit, and total bilirubin (TBIL), should be considered while adjusting tacrolimus levels. This case report aims to introduce clinicians and their teams to taking the pharmacokinetic prediction equation into consideration for a better understanding of tacrolimus dosage adjustment during the early postoperative LT.
METHODS: In this case report, an 18-year-old male patient of Thai ethnicity was admitted for orthotropic liver transplantation, and tacrolimus was prescribed as a cornerstone immunosuppressive agent. In the immediate postoperative period, which is the most challenging period in liver transplantation, the population pharmacokinetics predictive equation was clinically used to assist in dosage adjustment of tacrolimus by considering the significant clinical factors in this case. Hemoglobin and total bilirubin levels were deemed significant clinical factors affecting the oral clearance (CL/F) of tacrolimus. First, a decrease in the Hb concentration increases the free drug concentration and therefore increases the CL/F of tacrolimus. Second, an elevated TBIL decreases the biliary excretion of tacrolimus, resulting in a decrease in the CL/F of tacrolimus. Thus, dose optimization of tacrolimus would be accurate when taking the pharmacokinetic prediction equation into consideration. Moreover, the results may contribute to a better understanding of tacrolimus pharmacokinetic variability in each transplant patient during the immediate postoperative course.
CONCLUSIONS: Hemoglobin and total bilirubin were significant clinical factors influencing the oral clearance of tacrolimus early after liver transplantation. A decrease in the hemoglobin concentration would increase the free drug concentration and therefore increase the oral clearance of tacrolimus. An elevated total bilirubin decreases the biliary excretion of tacrolimus, resulting in a decrease in the oral clearance of tacrolimus.

UNASSIGNED: This study aimed to evaluate both short-term and long-term changes in the lamina cribrosa curvature index (LCCI) following trabeculectomy and investigate the factors influencing these changes.
UNASSIGNED: In this retrospective, observational study, 40 eyes of 40 patients with glaucoma who underwent trabeculectomy and had a follow-up of at least 2 years were included. Optic nerve head area was scanned by using spectral-domain optical coherence tomography before surgery (Pre_OP), within 6 months postoperatively (Post_OP1), and at the last visit (Post_OP2). LCCI values calculated from B-scan images at six different planes (0°, 30°, 60°, 90°, 120°, and 150°) and their mean values were compared. Univariate and multivariate linear regression analyses were used to identify the clinical factors associated with the amount of LCCI changes.
UNASSIGNED: The mean follow-up time was 38.3 ± 16.8 months. At Post_OP1, the mean LCCI decreased from 9.28 ± 2.58 to 7.91 ± 2.57 (P < 0.001), and the mean intraocular pressure decreased from 22.0 ± 7.6 mm Hg to 12.2 ± 3.8 mm Hg (P = 0.001). At Post_OP2, the mean LCCI was maintained at 7.74 ± 2.49 (P = 0.56 when compared to Post_OP1 and P < 0.001 when compared to Pre_OP). The mean intraocular pressure was 12.6 ± 5.4 mm Hg (P = 0.67 when compared to Post_OP1 and P < 0.001 when compared to Pre_OP). Long-term LCCI changes were associated with baseline age (P = 0.04), spherical equivalent (P = 0.02), mean IOP during follow-ups (P = 0.02), and preoperative LCCI (P = 0.04).
UNASSIGNED: Glaucomatous eyes undergoing trabeculectomy demonstrated reductions in the LCCI after a mean follow-up of over 3 years. Greater long-term LCCI reduction was associated with younger age, lower mean IOP during follow-up period, greater spherical equivalent refractive error, and preoperative LCCI.

Colorectal cancer (CRC) is a major health problem worldwide and is usually detected in advanced stages, although it is highly treatable with early detection. The aim of this study was to examine the serum levels of various cytokines involved in the pathogenesis of CRC. The study included 29 patients and 30 healthy volunteers. Blood samples were collected twice from the patient group, before and after surgery, and these samples were evaluated for interleukin (IL) 4, 10, 23r, 37, 38, 40 and interferon (IFN) gamma levels. The results showed that IL-4 and IL-38 levels were significantly lower in the preoperative serum samples of the patient group compared to the control group (p < 0.001 and p = 0.01, respectively), while IL-4, IL-10, IL-38 and IL-40 levels increased significantly in the postoperative period (p = 0.004, p = 0.02, p = 0.03 and p = 0.004, respectively). These findings may contribute to the development of immunotherapy agents in the treatment of CRC. However, comprehensive studies on larger patient groups are needed to fully understand the role of cytokines in CRC pathogenesis.

UNASSIGNED: To develop a predictive model using machine learning for levothyroxine (L-T4) dose selection in patients with differentiated thyroid cancer (DTC) after resection and radioactive iodine (RAI) therapy and to prospectively validate the accuracy of the model in two institutions.
UNASSIGNED: A total of 266 DTC patients who received RAI therapy after thyroidectomy and achieved target thyroid stimulating hormone (TSH) level were included in this retrospective study. Sixteen clinical and biochemical characteristics that could potentially influence the L-T4 dose were collected; Significant features correlated with L-T4 dose were selected using machine learning random forest method, and a total of eight regression models were established to assess their performance in prediction of L-T4 dose after RAI therapy; The optimal model was validated through a two-center prospective study (n=263).
UNASSIGNED: Six significant clinical and biochemical features were selected, including body surface area (BSA), weight, hemoglobin (HB), height, body mass index (BMI), and age. Cross-validation showed that the support vector regression (SVR) model was with the highest accuracy (53.4%) for prediction of L-T4 dose among the established eight models. In the two-center prospective validation study, a total of 263 patients were included. The TSH targeting rate based on constructed SVR model were dramatically higher than that based on empirical administration (Rate 1 (first rate): 52.09% (137/263) vs 10.53% (28/266); Rate 2 (cumulative rate): 85.55% (225/263) vs 53.38% (142/266)). Furthermore, the model significantly shortens the time (days) to achieve target TSH level (62.61 ± 58.78 vs 115.50 ± 71.40).
UNASSIGNED: The constructed SVR model can effectively predict the L-T4 dose for postoperative DTC after RAI therapy, thus shortening the time to achieve TSH target level and improving the quality of life for DTC patients.

BACKGROUND: Visual quality after corneal refractive surgery is linked to the postoperative effective optical zone (EOZ). This study aims to compare long-term changes in the EOZ following small incision lenticule extraction (SMILE) and femtosecond laser-assisted in-situ keratomileusis (FS-LASIK) for moderate and high myopia.
METHODS: This study included 42 patients (72 eyes) who underwent either SMILE (36 eyes) or FS-LASIK (36 eyes). A custom software program based on the tangential curvature difference map of the Pentacam HR (Oculus Optikgeräte GmbH) was used to define the EOZ at 3 and 7 years postoperatively. The EOZ, its chronological changes compared to the programmed optical zone (POZ), and the corneal wavefront aberrations following SMILE and FS-LASIK were analyzed. Correlations between the EOZ changes and relevant parameters were evaluated.
RESULTS: Three years postoperatively, EOZ following SMILE and FS-LASIK were 5.13 ± 0.27 mm and 4.70 ± 0.24 mm (P < 0.001), respectively. Seven years postoperatively, EOZ following SMILE and FS-LASIK decreased to 5.03 ± 0.28 mm and 4.63 ± 0.23 mm (P < 0.001), respectively. At postoperative 7 years, the percentages of EOZ/POZ were negatively correlated with Q-value changes (β = -5.120, P = 0.009) following SMILE and positively correlated with the cylinder correction (β = 1.184, P = 0.004) following FS-LASIK. The induced spherical aberrations in the SMILE group were less than those in the FS-LASIK group (P < 0.05) and were negatively correlated with the EOZ/POZ (β = -16.653, P < 0.001).
CONCLUSIONS: The EOZ following SMILE was larger than that following FS-LASIK in the long postoperative term for moderate and high myopia. Furthermore, a continual reduction in the EOZ was noted after both surgical modalities.

UNASSIGNED: To compare the effects between telerehabilitation and in-person rehabilitation on physical function, pain and quality of life in patients with breast cancer after surgery.
UNASSIGNED: Randomized, controlled, and parallel study that involved post-surgical oncological breast surgery patients who were female and aged between 18 and 70 years. The study was conducted in an outpatient environment, and the participants were randomized using a computer system. Population was divided into 2 groups: G1 (n = 20), who received face-to-face care, and G2 (n = 24), who received telerehabilitation. Participants were followed for 15 and 45 days postoperatively. The study\'s primary outcomes were based on 44 patients (n = 44). Values of changes in quality of life, range of motion (ROM), muscle strength, and upper limb functionality were compared for both groups during the 15 to 45 day postoperative.
UNASSIGNED: Both groups exhibited progressive improvements in range of motion, muscle strength, functionality, and quality of life over time (15- and 45-days post-operatively [PO]), indicating a positive response to treatment. Patients in G2 demonstrated more significant improvements in range of motion and muscle strength, as well as better functionality and quality of life compared to G1, particularly after 45 days PO. Additionally, G2 exhibited a more significant reduction in fatigue after 45 days PO.
UNASSIGNED: Telerehabilitation is a viable option with good usability, and has been shown to produce results similar to in-person physiotherapy in most cases, and even superior in some. Long-term intervention studies are needed for the development of telerehabilitation.
