Asymptomatic Bacteriuria and Urological Surgery: Risk Factor or Not? Results from the National and Multicenter TOCUS Database.

Current guidelines recommend screening and treatment of asymptomatic bacteriuria prior to all urological surgeries breaching the mucosa. But few evidence is supporting this recommendation. At least, risk stratification for postoperative urinary tract infection to support this strategy is lacking. The aim of this study was to define the associated factors for postoperative febrile infectious complications (urinary tract infection or surgical site infection) in urological surgery. We conducted a retrospective, multicentric study including all consecutive patients undergoing any urological surgery with preoperative urine culture. The primary outcome was the occurrence of a urinary tract infection or surgical site infection occurring within 30 days after surgery. rom 2016 to 2023, in 10 centers, 2389 patients were included with 838 (35%) positive urine cultures (mono/bi/polymicrobial). Postoperative infections occurred in 106 cases (4.4%), of which 44 had negative urine cultures (41%), 42 had a positive mono/bi-microbial urine cultures (40%) and 20 had a polymicrobial urine cultures (19%). In multivariable analysis, urinary tract infections during the previous 12 months of surgery (OR 3.43; CI 95 2.07-5.66; P < .001), monomicrobial/bimicrobial preoperative urine culture (OR 3.68; CI 95 1.57-8.42; P 0.02), polymicrobial preoperative urine culture (OR 2.85; CI 95 1.52-5.14; P < .001), operative time (OR 1.09; CI 95 1.04-1.15; P < .001) were independent associated factors for postoperative febrile infections. Positive urine culture, including preoperative polymicrobial urine culture, prior to urological surgery was associated with postoperative infection. Additionally, patients experiencing infectious complications also had a higher incidence of other complications. The effectiveness of systematic preventive antibiotic therapy for a positive urine culture has not been conclusively established.

The Efficacy of Diabetic Foot Treatment in a "TOSF" Pattern: A Five-Year Retrospective Study.

To evaluate the advantages and problems in the diagnosis and treatment of diabetic foot (DF) patients by analyzing the results of a 5-year follow-up of the organ system based (TOSF) treatment model. A retrospective study was conducted in 229 patients with diabetic foot. Chi-square test and rank-sum test were used to analyze the effects of patients' general condition, behavioral and nutritional status, degree of infection (inflammatory markers), comorbidity, diabetic foot grade/classification, and revascularization on readmission rate, amputation rate, all-cause mortality, incidence of other complications, and wound healing time. Logistic regression was used to analyze the risk factors affecting the prognosis of diabetic foot. Kaplan-Meier survival curve was used to analyze the differences in amputation rate and mortality rate at each time point. This study showed that nutritional status, degree of infection, and revascularization influenced readmission rates. General condition, behavior and nutritional status, degree of infection, Wagner grade and revascularization affect the amputation rate. General conditions, behavioral and nutritional status, degree of infection, comorbidities, classification and revascularization affect the mortality of patients. Age and white blood cell(WBC) count affected the incidence of other complications. Influence of infection degree and Wagner grade and revascularization in patients with wound healing time. Revascularization was an independent protective factor for readmission, amputation, and mortality.Elevated serum inflammatory markers are an independent risk factor for amputation. Hypoproteinemia is an independent risk factor for mortality. In the "TOSF" diagnosis and treatment pattern, diabetic foot patients have a good prognosis. Special attention should be paid to the screening and revascularization of lower extremity vascular disease in patients with diabetic foot.

Comparison of upfront haploidentical hematopoietic stem cell transplantation and salvage haploidentical hematopoietic stem cell transplantation after immunosuppressive therapy in children with acquired severe aplastic anemia - a multicenter study.

For children with severe aplastic anemia, if the first immunosuppressive therapy (IST) fails, it is not recommended to choose a second IST. Therefore, for patients without matched sibling donor (MSD) and matched unrelated donor (MUD), haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) can be chosen as a salvage treatment. This article aims to explore the comparison between upfront Haplo-HSCT and salvage Haplo-HSCT after IST. 29 patients received salvage Haplo-HSCT, and 50 patients received upfront Haplo-HSCT. The two groups received Bu (Busulfan, 3.2mg/kg/d*2d on days -9 to-8), CY (Cyclophosphamide, 60mg/kg/d*2d on days -4 to-3), Flu (fludarabine, 40mg/m2/d*5d on days -9 to -5) and rabbit ATG (Anti-thymocyte globulin, total dose 10mg/kg divided into days -4 to -2). The OS of the salvage Haplo-HSCT group showed no difference to the upfront Haplo-HSCT group (80.2 ± 8.0% vs. 88.7 ± 4.8%, p=0.37). The FFS of the salvage Haplo-HSCT group also showed no difference to the frontline Haplo-HSCT group (75 ± 8.2% vs. 84.9 ± 5.3%, p=0.27). There was no significant difference in the incidence of other complications after transplantation between the two groups, except for thrombotic microangiopathy (TMA). In the grouping analysis by graft source, the incidence of II-IV aGVHD in patients using PBSC ± BM+UCB was lower than that in the PBSC ± BM group (p=0.010). Upfront Haplo-HSCT and salvage Haplo-HSCT after IST in children with acquired severe aplastic anemia have similar survival outcomes. However, the risk of TMA increases after salvage Haplo-HSCT. This article provides some reference value for the treatment selection of patients. In addition, co-transplantation of umbilical cord blood may reduce the incidence of GVHD.

Effectiveness of Different Noninvasive Physiotherapy in Relieving Postlaparoscopic Shoulder pain: A Protocol for Systematic Review and Network Meta-Analysis.

Shoulder pain is one of the most common symptoms after laparoscopic surgery, which seriously affects people's health and quality of life. Many clinical studies have shown that noninvasive physiotherapy is the most beneficial treatment for patients, but the best approach for various noninvasive physiotherapy is unclear. The purpose of this study protocol is to compare the effectiveness of different noninvasive physiotherapy in relieving postlaparoscopic shoulder pain (PLSP). We will search ten electronic databases including PubMed, Web of Science, Medline, Scopus, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), CNKI, WanFang Data and VIP databases from their inception to November 2023. We will select randomized controlled trials (RCTs) to evaluate the effectiveness of noninvasive physiotherapy on PLSP. Our primary outcome will be to measure the intensity of shoulder pain at 24 and 48 hours after the end of the noninvasive intervention in the included study. Secondary outcomes include incidence of shoulder pain at 24 and 48 hours, postoperative nausea / vomiting and incidence of other complications after noninvasive intervention. Then, standard network meta-analysis will be conducted using Review Manager 5.4 and STATA 18. Our systematic review and network meta-analysis will identify the best noninvasive physiotherapy for PLSP patients. This systematic review will address the existing knowledge gap regarding best practice for relieving PLSP with noninvasive physiotherapy. The results of this network meta-analysis will help medical staff and patients choose the best method to relieve the PLSP. Furthermore, we hope that the results of this study will provide evidence-based for the improvement of guidelines and facilitate the decision sharing process. PROSPERO CRD42023481829.

Safety and efficacy of day anterior cervical discectomy and fusion procedure for degenerative cervical spondylosis: a retrospective analysis

ObjectiveOur study aimed to develop a day anterior cervical discectomy and fusion (ACDF) procedure to treat degenerative cervical spondylosis (DCS). The goal was to analyze its clinical implications, safety, and early effects to provide a better surgical option for eligible DCS patients.MethodsA retrospective analysis was performed to identify DCS patients who underwent day ACDF from September 2022 to August 2023. The operative time, intraoperative blood loss, postoperative drainage, preoperative and postoperative visual analog scale (VAS) scores, neck disability index (NDI) scores, Japanese Orthopedic Association (JOA) scores, JOA recovery rate (RR), incidence of dysphagia-related symptoms, 30-day hospital readmission rate, and incidence of other complications were recorded to evaluate early clinical outcomes. Radiography was performed to assess the location of the implants, neurological decompression, and cervical physiological curvature.ResultsAll 33 patients (23 women and 10 men) underwent successful surgery and experienced significant symptomatic and neurological improvements. Among them, 26 patients underwent one-segment ACDF, 5 underwent two-segment ACDF, and 2 underwent three-segment ACDF. The average operative time was 71.1 ± 20.2 min, intraoperative blood loss was 19.1 ± 6.2 mL, and postoperative drainage was 9.6 ± 5.8 mL. The preoperative VAS and NDI scores improved postoperatively (7.1 ± 1.2 vs. 3.1 ± 1.3 and 66.7% ± 4.8% vs. 24.1% ± 2.5%, respectively), with a significant difference (P < 0.01). Moreover, the preoperative JOA scores improved significantly postoperatively (7.7 ± 1.3 vs. 14.2 ± 1.4; P < 0.01) with an RR of 93.9% in good or excellent. Postoperative dysphagia-related symptoms occurred in one patient (3.0%). During the follow-up period, no patient was readmitted within 30 days after discharge; however, an incisional hematoma was reported in one patient on the 6th day after discharge, which was cured by pressure dressing. The postoperative radiographs revealed perfect implant positions and sufficient nerve decompression in all patients. Furthermore, the preoperative cervical physiological curvature improved significantly after the operation (14.5° ± 4.0° vs. 26.3° ± 5.4°; P < 0.01).ConclusionsDay ACDF has good safety and early clinical efficacy, and it could be an appropriate choice for eligible DCS patients.

Clinical study on the selection of endoscopes and microscopes for transsphenoidal surgery of non-aggressive pituitary macroadenoma and microadenoma and the influencing factors of hyposmia after endoscopic transsphenoidal surgery.

Transsphenoidal surgery, including endoscopic and microscopic resection, is the first choice of treatment for pituitary tumors. With the widespread application of neuroendoscopy in recent decades, there has been a trend to replace microscopes. In clinical practice, we have found that in transsphenoidal surgery for non-invasive microadenomas and macroadenomas, microscopy can achieve a higher total resection rate, shorter operation time, lower incidence of postoperative complications, and faster recovery of olfaction. This study aimed to explore the selection of endoscopes and microscopes for non-aggressive transsphenoidal surgery for pituitary adenomas and the factors affecting olfactory recovery. From August 2019 to October 2022, 93 patients with non-aggressive microadenomas and macroadenomas via the transsphenoidal approach were selected from the First Affiliated Hospital of Harbin Medical University and treated with rich experience in pituitary tumor subspecialty microscopy and endoscopic surgery. Different surgical methods were used to divide the patients into microscopic (n = 35) and endoscopic (n = 58) groups. The total tumor removal rate, intraoperative blood loss, operation time and cost, postoperative hospital stay, recovery of visual function, postoperative changes in hormone levels, complication rate, and recovery from complications 3 months after the operation were compared between the two groups. There were no significant differences in the tumor removal rate, postoperative visual acuity, and visual field recovery between the two groups (p > 0.05). There was a significant difference in the recovery rate of olfactory function between the two groups 3 months after the operation (p < 0.05), and there was no significant difference in the incidence of other complications (p > 0.05); Compared with the two groups, the microscope group had shorter operation time, longer postoperative hospital stay, less average operation cost and less blood loss, and the difference was statistically significant (p < 0.05). The position of the nasal septum mucosal flap incision was a risk factor for hyposmia 3 months after the operation. Microsurgery and endoscopic surgery are suitable surgical treatments for nonaggressive microadenomas and macroadenomas. The total tumor removal and postoperative hormone remission rates of the two surgical methods were approximately the same. However, the microsurgery group had a shorter operation time, less intraoperative blood loss, faster olfactory function recovery, and a lower average operation cost. The position of the nasal septal mucosal flap incision was a risk factor for hyposmia at 3 months postoperatively. Hyposmia is less likely to occur when the superior edge of the nasal septal mucosal flap incision is not higher than the lower edge of the ipsilateral superior turbinate.

Tunneled Hemodialysis Catheter Tip Design and Risk of Catheter Dysfunction: An Australian Nationwide Cohort Study

Rationale & ObjectiveHemodialysis catheter dysfunction is an important problem for patients with kidney failure. The optimal design of the tunneled catheter tip is unknown. This study evaluated the association of catheter tip design with the duration of catheter function. Study DesignObservational cohort study using data from the nationwide REDUCCTION trial. Setting& Participants: 4722 adults who each received hemodialysis via one or more tunneled central venous catheters in 37 Australian nephrology services from December 2016 to March 2020. ExposureDesign of tunneled hemodialysis catheter tip, classified as symmetrical, step, or split. OutcomeTime to catheter dysfunction requiring removal due to inadequate dialysis blood flow assessed by the treating clinician. Analytical ApproachMixed, three-level accelerated failure time model, assuming a log-normal survival distribution. Secular trends, the intervention, and baseline differences in service, patient, and catheter factors were included in the adjusted model. In a sensitivity analysis, survival times and proportional hazards were compared among participants’ first tunneled catheters. Results355 of 3871 (9.2%), 262 of 1888 (13.9%), and 38 of 455 (8.4%) tunneled catheters with symmetrical, step, and split tip designs, respectively, required removal due to dysfunction. Step tip catheters required removal for dysfunction at a rate 52% faster than symmetrical (adjusted time ratio = 0.48, 95% CI = 0.34-0.69), and 76% faster than split tip catheters (adjusted time ratio = 0.24, 95% CI = 0.11-0.52) in the adjusted accelerated failure time models. Only symmetrical tip catheters had performance superior to step tip catheters in unadjusted and sensitivity analyses. Split tip catheters were infrequently used and had risks of dysfunction similar to symmetrical tip catheters. The cumulative incidence of other complications requiring catheter removal, routine removal, and death prior to removal were similar across the three tip designs. LimitationsTip design was not randomized. ConclusionsSymmetrical and split tip catheters had a lower risk of catheter dysfunction requiring removal than step tip catheters.Funding: Grants from government (Queensland Health, Safer Care Victoria, Medical Research Future Fund, National Health and Medical Research Council, Australia), academic (Monash University), and not-for-profit (ANZDATA Registry, Kidney Health Australia) sources.

Cryoballoon versus radiofrequency catheter ablation for atrial fibrillation: insights from the Netherlands Heart Registration (2013-2021)

Abstract Background Cryoballoon ablation has emerged as a viable alternative to radiofrequency (RF) ablation in the treatment of atrial fibrillation (AF) with catheter ablation. Randomized trials and observational studies have demonstrated no statistically significant difference in the overall safety, efficacy, and effectiveness of RF and cryoballoon technologies. Despite over a decade of cryoballoon ablation use, there is limited population-level data comparing uptake in the utilization, populations referred, complications, and rates of repeat ablation of cryoballoon versus RF ablation. Purpose Our objective was to compare the real-world temporal trends in the utilization and complication rates of cryoballoon versus RF ablation for AF in the Netherlands between 2013 and 2021. Methods The Netherlands Heart Registration was used for the present study and included all consecutive patients who underwent AF ablation at 16 hospitals in the Netherlands (2013-2021). Only patients who underwent RF or cryoballoon ablation were included. Crude, age-, and sex-standardized annual incidence rates for AF ablation were calculated. Incidence rate ratios (IRR) and temporal trends were assessed with Poisson regression models with robust variances. Multivariable logistic regressions were used to compare the incidence complications between ablation methods. Results Of 37,538 AF ablations performed in the Netherlands, 20,799 (55.4%) and 12,549 (33.4%) underwent RF and cryoballoon ablations, respectively. At index AF ablation, patients referred to cryoballoon ablation were more likely women (34.3% vs 31.9%) and more frequently treated for paroxysmal AF (76.8% vs 68.0%) compared to RF patients [cryoballoon vs RF, respectively; p&amp;lt;0.05 for both]. Age of patients did not differ between ablation methods [median age for both: 63 (IQR 56-69) years; p=0.9]. From 2013 to 2021, the utilization of cryoballoon ablation increased by 16% for index ablations (p&amp;lt;0.05; Figure 1). Further, the population-level incidence of cryoballoon ablation was similar to RF ablation for index ablations from 2016 onwards (Figure 1). Repeat ablations (n=10,511) were primarily performed with RF (91.5%). Patients with cryoballoon ablation had a reduced risk of referral for repeat ablation [aHR 0.7 (95% CI 0.6-0.7)]. After multivariable adjustment, cryoballoon ablation was a risk factor for phrenic nerve paralysis [aOR 18.6 (95% CI 9.5- 36.4)] and RF was a risk factor for cardiac tamponade [aOR 2.7 (95% CI 1.7-4.3)] and minor vascular complications [aOR 1.4 (95% CI 1.1-1.8)] for index ablation. No difference was detected for the incidence of other complications between ablation methods (Figure 2). Incidence of all complications remained stable over time (p&amp;gt;0.05 for both). Conclusion The utilization of cryoballoon and RF ablation has rapidly increased from 2013 to 2021 in the Netherlands. Further, cryoballoon was used as frequently as RF ablations for index AF ablation procedures from 2016 onwards.

Is Holmium Laser Enucleation of the Prostate Truly Size-Independent? A Critical Evaluation at the Extreme Ends of the Spectrum

To assess the outcomes of holmium laser enucleation of the prostate (HoLEP) at the extremes of the size spectrum, comparing whether the results are consistent for very large and small prostates. A retrospective review of 402 patient charts was conducted to compare the outcomes of HoLEP in patients with prostate size ≤40g (group 1), 41-200g (group 2), and >200g (group 3). Various preoperative, perioperative, and postoperative variables were collected. HoLEP showed comparable voiding outcomes among all 3 groups, although patients with small prostates had a higher International Prostate Symptom Score during follow-up (P=.022). We noted a higher rate of perioperative blood transfusion in patients with very large prostates (P=.019) and a higher rate of transient acute urinary retention (AUR) in group 1 when compared to group 3 (P=.048). Patients with smaller prostates had a higher rate of bladder neck stenosis and urethral strictures, but the differences were not found to be statistically significant. The incidence of other complications, length of hospital stay, and catheterization duration did not differ significantly among the groups. HoLEP has consistent and safe outcomes across a wide range of prostate sizes. Although, the risk of blood transfusion is higher in patients with very large prostates and the risk of transient AUR is greater in patients with small glands, the overall efficacy and safety of HoLEP are not significantly influenced by prostate size.

MEsh FIxation in Laparoendsocopic Repair of Large M3 inguinal hernias: multicenter, double-blinded, randomized controlled trial—study protocol for a MEFI Trial

BackgroundInternational guidelines of groin hernia treatment strongly recommend to fixate the mesh in large M3 medial defects during TAPP/TEP procedures. The main purpose of fixation is to decrease the recurrence rate which is alarmingly high in case of those defects. In 2022, a team consisting of hernia surgeons and scientists from universities of technology conducted an experimental study with the use of 3D groin model to verify the hypothesis that fixation is not necessary in above cases. Experiment showed that rigid and anatomically shaped meshes are able to maintain its position in the groin without fixation. Similar conclusions were recently published in Swedish database registry analysis. To confirm above results, we decided to conduct a multicenter randomized controlled trial.MethodsMain objective of MEFI Trial is to verify the hypothesis that non-fixation of spatial, standard polypropylene meshes is non-inferior to fixation of flat, polypropylene lightweight meshes in M3 hernias by laparoendoscopic approach. Eleven large surgery centers in Poland having proficiency in laparoendoscopic groin hernia repairs were recruited for this study. Recurrence in 12-month follow-up was set as a primary endpoint. Pain sensation (Visual Analog Scale) and incidence of other complications (hematoma, seroma, SSI) were also noted. Based on the statistical analysis, minimal sample size in both arms was established at 83–102. The first arm (control) consists of patients undergoing a repair with the use of a flat, macroporous mesh with fixation using histoacryl glue. In the second arm, patients will be operated with the use of anatomically shaped, standard-weight mesh without fixation. Study will be double-blinded (patient/surgeon). After the dissection of preperitoneal space, surgeon will open a sealed envelope and find out which technique he will have to perform. Follow-up will be performed by Study Secretary (also blinded to the method used) via phone call 3 and 12 months after surgery.DiscussionBased on experimental study and recent registry analysis, we believe that the recurrence rate in both groups would be on the same level, giving hernia societies a strong argument for amending the guidelines.Trial registrationClinicalTrials.gov NCT05678465.

Ligamentum teres hepatis wrapping of the gastroduodenal artery stump for protection in total laparoscopic pancreaticoduodenectomy: a single-center experience.

Hemorrhage from the stump of the gastroduodenal artery (GDA) is a significant postoperative risk with pancreaticoduodenectomy (PD). Studies have shown that wrapping the GDA stump using the omentum or the falciform ligament can help prevent bleeding. We aimed to determine whether wrapping the GDA stump with the ligamentum teres hepatis (LTH) would reduce postoperative PD hemorrhage. We retrospectively reviewed data for 148 patients who underwent laparoscopic pancreatoduodenectomy (LPD) at our hospital from November 2015 to September 2021. We compared perioperative data from 63 LPD patients without wrapping of the GDA (unwrapped group) and 85 whose GDA stumps were wrapped (wrapped group). There were no significant differences in the groups' baseline characteristics. The postoperative GDA stump bleeding incidence was significantly lower in the wrapped group than that in the unwrapped group (7.9% vs. 0, respectively). There was also no significant difference in the incidence of other complications (intra-abdominal infection, postoperative pancreatic fistula (POPF), biliary fistula, and gastrointestinal bleeding). Using the LTH to wrap the GDA stump during LPD can reduce bleeding from the GDA stump but not the incidence of other complications.

Quantitative Evaluation of Periodontitis for Predicting the Occurrence of Postoperative Pneumonia After Oncologic Esophagectomy.

Periodontitis is a biofilm-associated inflammatory periodontal disease associated with postoperative complications after esophagectomy. However, few studies have evaluated the inflammatory burden posed by periodontitis quantitively for patients undergoing oncologic esophagectomy. This study aimed to clarify the relationship between periodontitis and postoperative pneumonia using periodontal inflammatory surface area (PISA). The study analyzed 251 patients who underwent esophagectomy for esophageal cancer. The patients were classified into low-PISA and high-PISA groups according to preoperative PISA, and the relationship between the occurrence and severity of postoperative pneumonia was investigated. The high-PISA group (n = 69) included more males (P < 0.001) and patients with poor performance status (P < 0.024). Postoperative pneumonia occurred more frequently in the high-PISA group than in the low-PISA group (31.9 % vs. 15.9 %; P = 0.008), whereas the incidences of other complications did not differ significantly. In addition, the incidence of severe pneumonia was significantly higher in the high-PISA group (7.2 % vs. 1.6 %; P = 0.038). In the multivariable analysis for adjustment of preoperative confounders, age older than 70 years (odds ratio [OR], 2.62; P = 0.006), high PISA (OR, 2.45; P = 0.012), and smoking history (OR, 2.78; P = 0.006) were the independent variables predicting postoperative pneumonia. Preoperative higher PISA was significantly associated with the occurrence of overall and severe postoperative pneumonia. The quantitative evaluation of periodontitis using PISA is a useful measure for predicting postoperative pneumonia, and intensive periodontal intervention may contribute to decreasing postoperative pneumonia.

Modified tragus edge incision and transmasseteric anteroparotid approach to condyle reconstruction.

This study aimed to analyze the application value of a modified tragus edge incision and transmasseteric anteroparotid approach to condyle reconstruction. Condyle reconstruction was performed in 16 patients (9 females and 7 males) with modified tragus edge incision and transmasseteric anteroparotid approach. After regular follow-up, the function of condyle reconstruction was evaluated by clinical indicators, such as parotid salivary fistula, facial nerve function, mouth opening, occlusal relationship, and facial scar. The morphology of rib graft rib cartilage was evaluated by imaging indicators, such as panoramic radiography, CT, and three-dimensional CT image reconstruction. At 6-36 months postoperative follow-up, all patients had good recovery of facial appearance, concealed incisional scar, no parotid salivary fistula, good mouth opening, and occlusion. One case had temporary facial paralysis and recovered after treatment. Radiographic evaluation further showed that costochondral graft survived in normal anatomic locations. The modified tragus edge incision and transmasseteric anteroparotid approach can effectively reduce parotid salivary fistula and facial nerve injury in condylar reconstruction. The surgical field was clearly exposed, and the incision scar was concealed without increasing the incidence of other complications. Thus, this approach is worthy of clinical promotion.

Anticoagulation practices and complications associated with Impella® support at an advanced cardiac center in the Middle East gulf region.

Anticoagulation during Impella® support is a challenge due to its complications and inconsistent practice across the globe. This observational, retrospective chart review included all patients with Impella® support at our advanced cardiac center at a quaternary care hospital in the Middle East gulf region. The study was conducted over six years (2016-2022), a time period during which manufacturer recommendations for purge solution, anticoagulation protocols as well as Impella® place in therapy and utilization were all evolving. We aimed to evaluate the efficacy of different anticoagulation practices and association with complications and outcomes. Forty-one patients underwent Impella® during the study period, including 25 patients with support for more than 12h, and are the focus of our analysis. Cardiogenic shock (n = 25, 60.9%) was the primary indication for Impella®, followed by facilitating high-risk PCI (n = 15, 36.7%) and left ventricular afterload reduction in patients undergoing veno-arterial extracorporeal membrane oxygenation (n = 1, 2.4%). Our overall Impella® usage evolved over the years from a primary use to facilitate a high-risk PCI to the recent more common use of LV unloading in cardiogenic shock. No patients experienced device malfunction and the incidence of other complications including ischemic stroke and bleeding were comparable to those reported in the literature (12.2% and 24% respectively). The 30-day all-cause mortality of 41 patients was 53.6%. In line with the evolving recommendations and evidence, we observed an underutilization of non-heparin-based purge solutions and inconsistent management of anticoagulation in the setting of both Impella® and VA ECMO which necessitates more education and protocols.

Analgesic effect of subcutaneous injection of different concentrations of methylene blue after hemorrhoidectomy: A retrospective study.

Subcutaneous injection of methylene blue around the anus may help reduce postoperative pain. However, the concentration of methylene blue is still controversial. Therefore, Our study aims to investigate the efficacy and safety of different methylene blue injected concentrations subcutaneously in pain treatment after hemorrhoidectomy. A total of 180 consecutive patients with grade III or IV hemorrhoids from March 2020 to December 2021 were reviewed. All patients underwent hemorrhoidectomy under spinal anesthesia and were divided into three groups. Group A received subcutaneous injection of 0.1% methylene blue after hemorrhoidectomy, group B received subcutaneous injection of 0.2% methylene blue, and Group C did not received subcutaneous injection of methylene blue. The primary outcome measures were the visual analog scale (VAS) pain score on postoperative days 1, 2, 3, 7, 14, and total analgesic consumption within 14 days. Secondary outcomes were complications after hemorrhoidectomy, including acute urinary retention, secondary bleeding, perianal incision edema, and perianal skin infection, and the Wexner scores used to assess the level of anal incontinence at one and three months after surgery. There was no significant difference among three groups in sex, age, course of the disease, hemorrhoid grade and the number of incisions, and there was no significant difference in the volume of methylene blue injected between group A and group B. The VAS pain score and total analgesics consumption within 14 days in group A and group B were significantly lower than those in group C, but the differences between group A and group B were not statistically significant. The Wexner scores of group B were significantly higher than those of group A and group C one month after the operation, but the differences between group A and group C were not statistically significant. In addition, the Wexner score among three groups decreased to zero at three months after operation. There was no significant difference in the incidence of other complications among three groups. The perianal injection of 0.1% methylene blue and 0.2% methylene blue have a similar analgesic effect in pain treatment after hemorrhoidectomy, but 0.1% methylene blue has higher safety.

Impact of premature rupture of membranes on clinical outcomes of extremely premature infants: A propensity score matching study.

Premature rupture of membranes (PROM) is a common cause of extremely premature infants (EPIs) and also leads to adverse preterm complications. However, the effect of PROM on EPIs remains contradictory. This study used propensity score matching (PSM) to adjust the baseline characteristics to explore the impact of PROM on clinical outcomes of extremely premature infants (EPIs). Medical data of 470 EPIs at gestational age < 28weeks who received prenatal examination in our hospital between January 1, 2015 and December 31, 2020 were analyzed retrospectively. According to the presence or absence of PROM, they were divided into a PROM group and a non-PROM group. Ten covariates including birth weight, male sex, artificial conception, cesarean delivery, 5-min Apgar score ≤ 7, oligohydramnios, gestational hypertension, preeclampsia, antenatal steroid use, and complete steroid treatment were matched 1:1 by PSM. The major complication occurrence and mortality during hospitalization were compared between the two groups by t-test, nonparametric test or test. Among the 470 infants enrolled, 157 (33.4%) were in the PROM group and 313 in the no-PROM group. After matching the ten confounding factors,276 cases were successfully enrolled. The incidence of early pulmonary hypertension (EPH) and severe retinopathy of prematurity (ROP) in the PROM group were higher than those in the no-PROM group [44.2% (61/138) vs. 29.0% (40/138); 34.8% (48/138) vs. 21.7% (30/138), x 2 = 6.886 and 5.790, both P < 0.05]. However, there was no significant difference in the in-hospital mortality and the incidence of other major complications between the two groups (all P > 0.05). PROM increased the incidence of EPH and severe ROP in EPI, but had no significant impact on in-hospital mortality, length of hospital stay, and the incidence of other complications.

Radiosurgical interventions in the prevention of post-resection liver failure

Aim. To evaluate the effectiveness of percutaneous ALPPS as a method for preventing post-resection liver failure.Materials and methods. The methodology involved a retrospective study of the results of portovenous embolization and percutaneous radiofrequency assisted liver partition with portal vein embolization (PRALLPS), in case of the future liver volume &lt;40% . The degree of hypertrophy of the future liver remnant and its rate were assessed in two groups. Complications of manipulation and frequency of postresection hepatic failure were studied.Results. In the first stage, portenous embolization was successfully performed in 38 patients and PRALLPS was successfully performed in 47 patients. In the second stage, liver resection was performed in 27 (71.1%) and 33 (70%) patients. The most frequent complication of PRALLPS was bile accumulation in the radiofrequency ablation area (13.1%). The incidence of other complications of the first stage did not differ between groups. No differences in blood loss or incidence of liver failure were reported after the second stage. No fatal outcomes reported. The mean degree of hypertrophy and growth did not differ between the groups. The mean time of hypertrophy of the future liver remnant after percutaneous radiofrequency assisted partition of the parenchyma with portal vein embolization and portenous embolization was 13 ± 5 and 18 ± 7 days (p = 0.008).Conclusion. The results of percutaneous radiofrequency assisted liver partition with portal vein embolization are comparable in terms of safety with those of portenous embolization. Radiofrequency partition of the parenchyma with portal vein embolization enables optimal hypertrophy of the future liver remnant to be achieved faster.

Limb salvage surgery reconstructive techniques following long-bone lower limb oncological resection: a systematic review and meta-analysis.

Limb salvage surgery (LSS) is now considered the gold standard surgical treatment for lower limb bone sarcomas. However, there is a paucity of literature comparing the various LSS reconstructive options. The aim of this systematic review and meta-analysis was to compare functional outcomes and complications of LSS reconstructive techniques. The primary aim of the meta-analysis was to determine functional outcomes from the pooled data utilizing the Musculoskeletal Tumour Society score (MSTS). Comparisons could then made for this outcome between biological and prosthetic, vascularised and non-vascularised, and prosthetic and composite reconstructions. The secondary aim was to compare complication outcomes of each reconstruction. Standardized mean difference (Cohen's d) and odds ratios were estimated using a random effects model. Fourteen studies with a total of 785 patients were included. We found structural failure was 75% less likely to occur in prosthetic reconstruction compared to biological (OR=0.24; 95% CI: 0.07-0.79; P=0.02). We did not find any evidence of difference in function (MSTS score) between vascularised verses non-vascularised reconstructions (Cohen's d=-1.14; 95% CI=-3.06 to 0.78; I2 =87%). Other analyses comparing complications found no difference between the reconstructive groups. The study found no correlation between functional outcomes and the type of LSS reconstruction. Structural failure was more likely to occur in biological when compared with prosthetic reconstruction. There was no correlation between the incidence of other complications and the type of LSS technique. This suggests a role for improved approaches to reconstruction methods including bioprinting and bioresorbable devices.

The enhanced recovery after surgery (ERAS) protocol in elderly patients with acute cholecystitis: A retrospective study.

Enhanced recovery after surgery (ERAS) protocol is a perioperative management theory aimed at reducing the injury of surgical patients and accelerating postoperative recovery. It has been widely recognized and applied in elective surgery. This study aimed to evaluate the clinical value of the ERAS protocol during the perioperative period of laparoscopic cholecystectomy in elderly patients with acute cholecystitis. This study aimed to evaluate the clinical value of the ERAS protocol during the perioperative period of laparoscopic cholecystectomy in elderly patients with acute cholecystitis. We collected medical data from 126 elderly patients with acute cholecystitis from October 2018 to August 2021. Among the 126 patients, 70 were included in the ERAS group and 56 in the traditional group. We analyzed the clinical data and postoperative indicators of the 2 groups. No significant differences were observed regarding the general characteristics of the 2 groups (P > .05). The ERAS group had significantly earlier time to first flatus, time to first ambulation, and time to solid intake, compared with the traditional group (P < .001); additionally, the ERAS group had significantly shorter stay and gentler feeling of postoperative pain (P < .001). Furthermore, the ERAS group had significant incidences of lower postoperative lung (P = .029) and abdominal cavity infection (P = .025) compared to the traditional group. No significant difference was observed regarding the incidences of other postoperative complications between the 2 groups (P > .05). The ERAS protocol helps reduce elderly patients' stress reactions and accelerate postoperative recovery. Thus, it is effective and beneficial to implement the ERAS protocol during the perioperative period of elderly patients with acute cholecystitis.

Maternal and neonatal safety of COVID-19 vaccination during the peri-pregnancy period: A prospective study.

To investigate the safety of inactivated COVID-19 vaccine in Chinese pregnant women and their fetuses when inoculated during the peri-pregnancy period. Eligible pregnant women were prospectively collected and divided into a vaccine group (n = 93) and control group (n = 160) according to whether they had been vaccinated against COVID-19 within 3 months before their last menstruation period (LMP) and after pregnancy. Demographic data of couples, complications during pregnancy and delivery of pregnant women, and data of newborns at birth were collected. Sixty-six women were vaccinated with a median time of 35.5 (range = 0-91) days before LMP, and 27 women were vaccinated with a median time of 17 (range = 1-72) days after LMP. The incidence of premature rupture of membrane (PROM) in the vaccine group was significantly higher than that in the control group (16.13% vs. 6.88%, p = 0.019). Multivariate logistic regression analysis revealed that maternal peri-pregnancy COVID-19 vaccination was not an independent risk factor for PROM (odds ratio: 2.407, 95% confidence interval: 0.932-6.216, p = 0.069). There was no difference in the incidence of other complications during pregnancy and delivery between the two groups. A total of 253 neonates were delivered, including two cases with congenital abnormalities in each group. The incidence of congenital abnormalities between the two groups was similar (2.15% vs. 1.25%, p = 0.626). There was no difference in neonatal length, weight, head circumference, and Apgar score between the two groups (p > 0.05), but the incidence of neonatal jaundice in the vaccine group was significantly higher than that in the control group (20.43% vs. 7.5%, p = 0.002). Multivariate logistic regression analysis revealed that maternal peri-pregnancy vaccination, postpartum blood loss, cesarean section, 1-min Apgar score, and paternal smoking were independent risk factors for neonatal jaundice. It is safe for pregnant women and their fetuses to be inoculated the inactivated COVID-19 vaccine during the peri-pregnancy period, but attention should be paid to neonatal jaundice.
