Preoperative forced expiratory volume in one second and postoperative respiratory outcomes in nonpulmonary and noncardiac surgery: a retrospective cohort study

BackgroundAlthough the usefulness of pulmonary function tests has been established for lung resection and coronary artery bypass surgeries, the association between preoperative pulmonary function test and postoperative respiratory complications in nonpulmonary and noncardiac surgery is inconclusive. The purpose of this study was to determine the association between preoperative forced expiratory volume in one second (FEV1) on pulmonary function test and the development of postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.MethodsAdult patients aged ≥ 18 years and who underwent nonpulmonary and noncardiac surgery with expected moderate to high risk of perioperative complications from June 2012 to March 2019 were included. The primary exposure was preoperative FEV1 measured by pulmonary function test within six months before surgery. The primary outcome was respiratory failure (i.e., invasive positive pressure ventilation for at least 24 h after surgery or reintubation) and/or death within 30 days after surgery. A logistic regression model was used to adjust for the respiratory failure risk index, which is a scoring system that predicts the probability of postoperative respiratory failure based on patient and surgical factors, and to examine the association between preoperative FEV1 and the development of postoperative respiratory failure and/or death.ResultsRespiratory failure and/or death occurred within 30 days after surgery in 52 (0.9%) of 5562 participants. The incidence of respiratory failure and/or death in patients with FEV1 ≥ 80%, 70%– < 80%, 60%– < 70%, and < 60% was 0.9%, 0.6%, 1.7%, and 1.2%, respectively. Multivariable logistic regression analysis showed no significant association between preoperative FEV1 and postoperative respiratory failure and/or death (adjusted odds ratio per 10% decrease in FEV1: 1.01, 95% confidence interval: 0.88–1.17, P = 0.838). Addition of FEV1 information to the respiratory failure risk index did not improve the prediction of respiratory failure and/or death [area under the receiver operating characteristics curve: 0.78 (95% confidence interval: 0.72–0.84) and 0.78 (95% confidence interval: 0.72–0.84), respectively; P = 0.84].ConclusionWe found no association between preoperative FEV1 and postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.

Hyaluronic Acid-Based Nanoparticles Loaded with Rutin as Vasculo-Protective Tools against Anthracycline-Induced Endothelial Damages.

Anthracycline-based therapies exert endothelial damages through peroxidation and the production of proinflammatory cytokines, resulting in a high risk of cardiovascular complications in cancer patients. Hyaluronic acid-based hybrid nanoparticles (LicpHA) are effective pharmacological tools that can target endothelial cells and deliver drugs or nutraceuticals. This study aimed to prepared and characterized a novel LicpHA loaded with Rutin (LicpHA Rutin), a flavonoid with high antioxidant and anti-inflammatory properties, to protect endothelial cells against epirubicin-mediated endothelial damages. LicpHA Rutin was prepared using phosphatidylcholine, cholesterol, poloxamers, and hyaluronic acid by a modified nanoprecipitation technique. The chemical-physical characterization of the nanoparticles was carried out (size, zeta potential, morphology, stability, thermal analysis, and encapsulation efficiency). Cytotoxicity studies were performed in human endothelial cells exposed to epirubicin alone or in combination with Free-Rutin or LicpHA Rutin. Anti-inflammatory studies were performed through the intracellular quantification of NLRP-3, MyD-88, IL-1β, IL-6, IL17-α, TNF-α, IL-10, and IL-4 using selective ELISA methods. Morphological studies via TEM and image analysis highlighted a heterogeneous population of LicpHA particles with non-spherical shapes (circularity equal to 0.78 ± 0.14), and the particle size was slightly affected by Rutin entrapment (the mean diameter varied from 179 ± 4 nm to 209 ± 4 nm). Thermal analysis and zeta potential analyses confirmed the influence of Rutin on the chemical-physical properties of LicpHA Rutin, mainly indicated by the decrease in the surface negative charge (from -35 ± 1 mV to -30 ± 0.5 mV). Cellular studies demonstrated that LicpHA Rutin significantly reduced cell death and inflammation when compared to epirubicin alone. The levels of intracellular NLRP3, Myd-88, and proinflammatory cytokines were significantly lower in epirubicin + LicpHA Rutin-exposed cells when compared to epirubicin groups (p < 0.001). Hyaluronic acid-based nanoparticles loaded with Rutin exerts significant vasculo-protective properties during exposure to anthracyclines. The overall picture of this study pushes towards preclinical and clinical studies in models of anthracycline-induced vascular damages.

Microinvasive intrascleral double continuous suture repair surgery for cyclodialysis clefts.

The traditional suturing method for cyclodialysis cleft usually requires an incision in the sclera for direct suturing, resulting in greater damage and a high risk of postoperative complications. The purpose of this work is to propose a newly intrascleral double continuous suture repair technique for the treatment of cyclodialysis clefts. Seven patients with cyclodialysis cleft underwent microinvasive intrascleral double continuous suture repair surgery to restore the attachment of the detached ciliary body to the sclera without scleral incision. All operations were performed by the same surgeon. Preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), slit lamp and corneal examination results, ultrasound biomicroscopy (UBM) and optical coherence tomography (OCT) results were recorded. Closure of the cyclodialysis cleft was achieved in 7 eyes and no obvious complications occurred after the operation. Intraocular pressure increased from preoperatively 6.8 ± 1.35 mmHg (range: 4.8-8.0 mmHg) to postoperatively 12.5 ± 4.0 mmHg (range: 8.0-20.0 mmHg) (paired sample T test, P < 0.01). Best-corrected Snellen visual acuity improved from preoperatively range 20/2000-20/63 to range 20/200-20/25 at final follow-up. In short, intrascleral double continuous suture repair surgical is safe and effective in treating cyclodialysis cleft, with minimal surgical trauma.

Improved outcome of COVID-19 over time in patients treated with CAR T-cell therapy: Update of the European COVID-19 multicenter study on behalf of the European Society for Blood and Marrow Transplantation (EBMT) Infectious Diseases Working Party (IDWP) and the European Hematology Association (EHA) Lymphoma Group

COVID-19 has been associated with high mortality in patients treated with Chimeric Antigen Receptor (CAR) T-cell therapy for hematologic malignancies. Here, we investigated whether the outcome has improved over time with the primary objective of assessing COVID-19-attributable mortality in the Omicron period of 2022 compared to previous years. Data for this multicenter study were collected using the MED-A and COVID-19 report forms developed by the EBMT. One-hundred-eighty patients were included in the analysis, 39 diagnosed in 2020, 35 in 2021 and 106 in 2022. The median age was 58.9 years (min-max: 5.2–78.4). There was a successive decrease in COVID-19-related mortality over time (2020: 43.6%, 2021: 22.9%, 2022: 7.5%) and in multivariate analysis year of infection was the strongest predictor of survival (p = 0.0001). Comparing 2022 with 2020–2021, significantly fewer patients had lower respiratory symptoms (21.7% vs 37.8%, p = 0.01), needed oxygen support (25.5% vs 43.2%, p = 0.01), or were admitted to ICU (5.7% vs 33.8%, p = 0.0001). Although COVID-19-related mortality has decreased over time, CAR T-cell recipients remain at higher risk for complications than the general population. Consequently, vigilant monitoring for COVID-19 in patients undergoing B-cell-targeting CAR T-cell treatment is continuously recommended ensuring optimal prevention of infection and advanced state-of-the art treatment when needed.

The Interrelationship between Diabetes Mellitus and Emotional Well-Being: Current Concepts and Future Prospects.

Diabetes mellitus is a lifelong metabolic disorder that impacts people's well-being and biopsychosocial status. Psychiatric problems and diabetes mellitus have a complex, reciprocal interaction in which one condition affects the other. In this narrative review, we provide an overview of the literature on the psychological effects of diabetes, expound on the evaluation of emotional disorders in the setting of diabetes, and suggest interventions aimed at enhancing both mental and physical health. Diabetes can make daily life complicated and stressful. Frequent blood glucose testing, taking medications on a regular basis, adhering to a tight diet plan, and exercising are some examples of the suggested daily routine of subjects with diabetes. Furthermore, comorbid diseases and typical diabetic complications can have a detrimental impact on quality of life. When mental health conditions coexist with diabetes mellitus, there is a greater likelihood of medication noncompliance, a decreased commitment to diabetes-related self-care, increased functional impairment, inadequate glycemic control, a higher risk of complications, and overall higher healthcare expenses. Thus, evaluation of the mental health status of patients with diabetes is crucial. When treating psychological issues and psychiatric disorders, a comprehensive biopsychosocial approach should be taken, and where appropriate, psychopharmacological therapies or psychotherapy should be applied. The goal of continuous education and assistance for self-care is to give individuals with the disease the information and abilities they need to control their condition over time.

A systematic review and meta-analysis of morbidity and pancreatic fistula after distal pancreatectomy with versus without prophylactic intra-abdominal drainage.

The omission of a prophylactic intra-abdominal drainage has been under debate in pancreatic surgery due to the high risk of complications and especially of postoperative pancreatic fistula (POPF). Recently, the second randomized controlled trial (RCT) and two propensity score-matched comparative studies assessing risks and benefits of a no-drainage policy versus prophylactic drainage after distal pancreatectomy (DP) have been published. This systematic review with meta-analysis provides an updated summary of the available evidence on this topic. RCTs and non-randomized comparative studies (NCS) investigating outcomes of no drainage versus drainage after DP were searched systematically in MEDLINE, Embase and CENTRAL. Random effects meta-analyses were performed, and the results presented as weighted odds ratios (OR) or mean differences (MD) with their corresponding 95% confidence intervals (c.i.). Subgroup analyses were performed to account for inter-study heterogeneity between RCTs and NCS. Two RCTs and six NCS with a total of 3,610 patients undergoing DP were included of whom 1,038 (28.8%) patients did not receive prophylactic drainage. A no-drainage policy was associated with significantly lower risks of POPF (OR 0.38, 95% c.i. 0.25-0.56; P<0.00001), reduced major morbidity (OR 0.64, 95% c.i. 0.47-0.89; P=0.008), less reinterventions (OR 0.70, 95% c.i. 0.52-0.95; P=0.02) and fewer readmissions (OR 0.69, 95% c.i. 0.54-0.88; P=0.003) as well as shorter length of hospital stay (MD -1.74, 95% c.i. -2.70- -0.78; P=0.0004). Subgroup analyses including only RCTs confirmed benefits of the no-drainage policy. A no-drainage policy is associated with reduced POPF and morbidity and can therefore be recommended as standard procedure in patients undergoing DP.

Predicting the probability of complications during prostatectomy in pa-tients with prostate cancer using machine learning methods

Objective. To determine the probabilities of predicting possible complications after surgery in patients with the diagnosis of prostate cancer using artificial intelligence methods. Materials and methods. Case histories of 701 patients who underwent prostatectomy were analyzed in the study. The anamnesis, findings of clinical, laboratory and instrumental study, as well as objective data of clinical observations were evaluated. The average age was 64.72. On the basis of the set of examination results, patients were selected according to the following inclusion criteria: prostate cancer patients without confirmed metastases with disease stage from T1N0M0 to T3N0M0; absence of previous and concomitant special treatment (immunotherapy or targeted therapy); informed consent to the surgery. Logistic regression, a binary classifier using a sigmoidal activation function on linear combinations of features, was used as a machine learning model. Results. It was determined that the logistic regression model based on selected parameters (prostate volume, pain syndrome, disease duration), predicts the probability of complications quite well (TPR=1). The overall accuracy of the model is: Accuracy=0.98. At the same time, it can be noticed from the agreement matrix that the trained model plays it safe and classifies some cases without complications incorrectly in 5.3% (FNR=0.053). However, the model never made an error and did not classify cases with a high risk of complications as those in which such a possibility was unlikely. Conclusions. The results obtained show that on the basis of just three parameters (prostate volume, pain syndrome, duration of the disease), it is possible to build a fairly good predictive model of the probability of complications after prostatectomy based on such machine learning method as logistic regression.

Nonunion of distal humeral fractures: Current concepts

The incidence of complex articular fractures of the distal humeral in adults has increased and will be growing in the future due to the greater incidence of high energy trauma and to the higher percentage of elderly population. Successful treatment is challenging for the needed balance between a stability of often comminuted fracture and early motion.Nonunion is a common complication after distal humerus fractures that is influenced by a variety of factors such as biology, in particular the blood supply of the metaphysis, the non-anatomical reduction of the fracture, the methods of fixation, and mechanical failure. These can involve the intra-articular or extra-articular areas. Clinical presentation may be mainly with a flail elbow in extra-articular nonunion or mainly with disfunction and stiffness for an intra-articular nonunion. However, the symptoms will depend on the degree of articular surfaces damage and the main localization of nonunion in the intra- and extra-articular region. The surgical treatment is usually required, being the non-operative treatment with a brace a reasonable option just for low-demand patients and with a high risk of complications. Despite a limited range of motion regained, the union rate achieved with internal fixation and bone grafting is substantially high.

Subacute inferior vena cava occlusion after treatment for advanced colorectal cancer: presentation and management

Thrombosis of the inferior vena cava is an uncommon condition and may not be recognized until the affected patient develops severe symptoms. It is associated with a higher risk of complications than other locations of deep venous thrombosis. Here we present a case of a 72-year-old man with bilateral occlusion of the external iliac veins and inferior vena cava. Keywords: Inferior vena cava, thrombosis, managemen

Biomarkers in the evaluation of cardiac involvement in systemic sclerosis.

Systemic sclerosis is a multisystemic disease for which the heart can be affected leading to cardiac complications and mortality. Up to 80% of patients with systemic sclerosis have cardiac involvement with varying levels of severity. Several molecules have been identified that can be used as markers of cardiac involvement. These biomarkers can arise directly from the heart due to cardiac damage from the disease such as cardiac troponins or from the underlying dysregulated immune process itself such as the proinflammatory cytokines including interleukin (IL)-6. This review aims to summarize the evidence on currently known biomarkers that are can be diagnostic, prognostic or predictive of primary cardiac involvement in systemic sclerosis. We also highlight potential new biomarkers based on the current understanding of the disease process. Clinical use of these markers can benefit patients through earlier identification of those with cardiac involvement, many of whom can be asymptomatic in the early stage, with higher risk of complications, with the overall goal to improve outcomes of these affected patients.

Phacofragmentation of Posteriorly Dislocated Lens Fragments: Limbal versus Pars Plana Approach

ABSTRACT Purpose To assess intra-operative complications and feasibility of removing crystalline lens fragments from the vitreous cavity through a limbal incision compared to a pars plana approach. Design Retrospective cohort study. Subjects 16 eyes underwent phacofragmentation via a limbal approach (Group A) and 9 eyes through a pars plana approach (Group B) at an academic center over a 10-year period. Methods We collected pre-operative, intra-operative, and post-operative data. We compared rates of intraoperative complications, including corneal wound burn, iris or capsular damage, retinal tears, and hemorrhage, and recorded post-operative BCVA and IOP measurements at the one-month post-operative appointment. We also compared rates of post-operative complications, including corneal edema, choroidal detachment, or retinal detachment. Main Outcome Measures Primary outcomes of the study were the rates of intraoperative complications and the feasibility of crystalline lens removal with the limbal approach. We defined the latter outcome as the ability to complete lens removal without switching to the pars plana route. Results Mean BCVA for group A was 1.6, and for group B was 2.0 (p = .19). There was no significant difference between the two groups in the incidence of intraoperative complications, including corneal wound burn, iris damage, anterior capsular tear, iatrogenic retinal tear, or suprachoroidal hemorrhage (p > .99). There was no significant difference in the incidence of intra-operative vitreous hemorrhage (p = .36). Additionally, there was no significant difference in post-operative corneal edema (p = .27), choroidal detachment (p = .52), or retinal detachment (p > .99). The mean post-operative BCVA was 1.0 in group A and 1.0 in group B (p = .75). We completed all cases in group A using the limbal approach without switching to the pars plana route. Conclusion Phacofragmentation through a limbal incision provides a feasible option for dropped nuclear fragment removal and is not associated with a higher risk of complications than the pars plana route.

Pro‑coagulant Considerations in Patients with Arterial Hypertension and Multifocal Atherosclerosis

The aim of the work to determine the features of hemostasis and blood rheology in patients with arterial hypertension (HTN) and multifocal atherosclerosis (MFA).Materials and methods. The study enrolled male and female patients aged from 40 to 70 years, including 59 patients with controlled stage I–II hypertension and multifocal vascular lesions (Group 1) and 42 patients with controlled stage III hypertension, who have suffered an ischemic stroke and have multifocal vascular lesions (Group 2). A test using the Thrombodynamics analyser system T-2 (GemaKor, LLC, Moscow, Russia) was performed to detect the impairment of hemostasis.Results. Patients with HTN and MFA have an impaired coagulation hemostasis system (an increase in the initial and stationary clot growth rate and the size of the clot, as well as the presence of spontaneous clots), which leads to a high residual risk of cerebral complications, despite BP lowering to target figures and control of lipid profile.Discussion. Elevated blood pressure in patients with MFA leads to endothelial dysfunction, which is accompanied by activation of coagulation and fibrinolysis pathways. These changes lead to a violation of microcirculatory hemostasis in the brain, the development and progression of cerebral ischemia, and subsequently the occurrence of stroke, both the first and repeated.Conclusion. An important result of this study is the first registered change in the coagulation link of hemostasis in patients with HTN and MFA aged from 40 to 70 years, which can be considered an additional criterion for stroke prediction.

Pattern of Cholelithiasis and Cholecystitis among Obese Patients

Introduction: Obesity is a major health problem in western society with rapidly increasing prevalence in most countries. The healthcare burden of obesity is far reaching but many of the consequences are yet to be fully understood. While there is a perception that obesity negatively impacts on health and stone formation in gall bladder there is conflicting evidence for this. Aims &amp; Objectives: To assess whether obesity impacts on the blood cholesterol level which leads to dislipidaemia and gall stone formation. To identify whether dislipidaemia causes cholelithiasis and cholecystitis among obese patient. Methods: Between 1st December, 2018 and 31thMay, 2019, patients admitted in dept of surgery at Shaheed Ziaur Rahman Medical College Hospital in Bogura, Bangladesh were enrolled. Following informed consent, BMI was assessed. High risk patients and complications were identified according to established criteria. Patients were grouped according to BMI categories as Normal, overweight, Obese grade-I and Obese grade-II. Various disease of gall bladder including stone formation and its complications were analysed on all obese patients treated at Shaheed Ziaur Rahman Medical College Hospital using a SQL database. Results: Total 59 people were available and consented for this study. 09 patients were excluded; 4 patient were obese but no cholelithiasis or cholecystitis, 3 patients were not agree to investigations and 2 patients declined study). The remaining 50 patients, 29 females and 21 males, included for analysis. The median age was 48 with a range from 18-55. A literature review found evidence of increased risk of dyslipidemia which induce stone formation in GB and inflammation of gall bladder associated with obesity. Conclusion: It is an important issue that obesity is increasing in our new generations. This study should take into account for the future health care researcher. This study has summarized the current body of literature and added to it by demonstrating in our cohort that obese patients were at increased risk of formation of gallstones. I have also provided the evidence that patients with increased BMI with cholelithiasis or cholecystitis or other comorbidities are associated with significantly greater cost to the healthcare system.

OVERVIEW OF ANEMIA AFTER SCOLIOSIS SURGERY IN THE INTENSIVE CARE UNIT (ICU) SOEHARSO ORTHOPEDIC HOSPITALINDONESIA

Anemia is a condition where the hemoglobin concentration is lower than normal. This condition reflects the lack of the normal number of erythrocytes in the body's circulation and consequently the amount of oxygen delivered to the body's tissues is also reduced. Miller &amp; Thompson (2019) scoliosis comes from the Greek word "scoliosis" which means crooked. Scoliosis is a complex three-dimensional deformity of the spine characterized by a lateral deviation of at least 10 degrees with spinal rotation and is usually associated with a reduction in the normal kyphotic curvature of the spine / hypokyphosis. The cause of bleeding in spinal surgery usually occurs more in cases of rigid scoliosis, pedicle subtraction osteotomy and vertebral column resection often referred to as triple column osteotomy and is considered a procedure with a high risk of complications with massive blood loss, reaching more than 10 liters (Jun. 2019). Based on its classification, this type of research is retrospective descriptive research. studies that discuss one or more variables separately, one-by-one, but do not examine the relationship between these variables, using the observation method with the subject being observed by looking at past conditions (Harlan &amp;Sutjiati, 2022). Using total sampling technique in sampling, the population is the medical records of patients admitted to the ICU, postoperative diagnosis of scoliosis with anemia, the sample size is 58 patient medical records. The variables observed were: indications for ICU admission and postoperative scoliosis, the inclusion criteria were medical record data for postoperative scoliosis patients with anemia admitted to the ICU for the period January 1 - December 31, 2022 and patients with the first scoliosis surgery. Based on this study, the following results were obtained: Most respondents were female (81%), the average age of respondents was 17 years. The most common type of scoliosis is adolescence idiopathic scoliosis (89.7%). The most Lenke classification is Lenke 3 (44.8%), the most types of surgery are stabilization, fusion, discectomy, laminectomy and osteotomy (56.9%). The duration of surgery was mostly 180-240 minutes (46.6%) with an average duration of surgery of 257 minutes, the average amount of bleeding was 884.5 ml, the average preoperative Hb was 13.3g/dL, the average postoperative Hb was 8.8 g/dL. The average postoperative Hemoglobin decrease was 5.3 g/dL, patients who were given blood transfusions (87.9%) with an average of 2.9 bags per patient, the most common type of transfused blood was PRC (90.2%).

Coronary artery disease management in older adults: revascularization and exercise training.

The mean age of patients with coronary artery disease (CAD) is steadily increasing. In older patients, there is a tendency to underutilize invasive approach, coronary revascularization, up-to-date pharmacological therapies, and secondary prevention strategies, including cardiac rehabilitation. Older adults with CAD commonly exhibit atypical symptoms, multi-vessel disease involvement, complex coronary anatomy, and a higher presence of risk factors and comorbidities. Although both invasive procedures and medical treatments are characterized by a higher risk of complications, avoidance may result in a suboptimal outcome. Often, overlooked factors, such as coronary microvascular disease, malnutrition, and poor physical performance, play a key role in determining prognosis, yet they are not routinely assessed or addressed in older patients. Historically, clinicians have relied on sub-analyses or observational findings to make clinical decisions, as older adults were frequently excluded or under-represented in clinical studies. Recently, dedicated evidence through randomized clinical trials has become available for older CAD patients. Nevertheless, the management of older CAD patients still raises several important questions. This review aims to comprehensively summarize and critically evaluate this emerging evidence, focusing on invasive management and coronary revascularization. Furthermore, it seeks to contextualize these interventions within the framework of improved risk stratification tools for older CAD patients, through user-friendly scales along with emphasizing the importance of promoting physical activity and exercise training to enhance the outcomes of invasive and medical treatments. This comprehensive approach may represent the key to improving prognosis in the complex and growing patient population of older CAD patients.

Complications following surgical treatment of patella fractures - a systematic review and proportional meta-analysis.

The aim of this systematic review and proportional meta-analysis was to identify complications of surgical treatment of patella fractures and to estimate their incidence. We extended existing knowledge on this topic by including several more recent and large-scale studies. This systematic review and meta-analysis were performed in accordance with the Cochrane Handbook for systematic reviews of interventions. After searching in PubMed, MEDLINE, EMBASE, Cochrane Library, and OpenGrey, all studies after 2000, with study populations > 100 patients, including only patients > 18 years and follow-up > 30 days, were included. Two independent authors assessed the literature search and extracted the data. The risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale. The meta-analysis was performed on complications pooled in infections, nonunion, symptomatic implant removal, and fixation failure. The data on complications were available from 14 studies, including a pool of 5659 patients. The most common complication was symptomatic implant removal, affecting. Surgically, treatment of patella fractures was associated with a high risk of complications. The most common complication was symptomatic implant removal, affecting 29.6% of patients. Other complications stated were fixation failure 5.2%, infections 3.1% and nonunion 1.7%.

General skin and nasal decolonization with octenisan® set before and after elective orthopedic surgery in selected patients at elevated risk for revision surgery and surgical site infections—a single-center, unblinded, superiority, randomized controlled trial (BALGDEC trial)

BackgroundThe preoperative body surface and nasal decolonization may reduce the risk of surgical site infections (SSI) but yields conflicting results in the current orthopedic literature.MethodsWe perform a single-center, randomized-controlled, superiority trial in favor of the preoperative decolonization using a commercial product (octenidine® set). We will randomize a total number of 1000 adult elective orthopedic patients with a high risk for SSI and/or wound complications (age ≥ 80 years, chronic immune-suppression, American Society of Anesthesiologists score 3–4 points) between a decolonization (octenisan® wash lotion 1 × per day and octenisan® md nasal gel 2–3 × per day; during 5 days) and no decolonization. Decolonized patients will additionally fill a questionnaire regarding the practical difficulties, the completeness, and the adverse events of decolonization. The primary outcomes are SSI and revision surgeries for postoperative wound problems until 6 weeks postoperatively (or 1 year for surgeries with implants or bone). Secondary outcomes are unplanned revision surgeries for non-infectious problems and all adverse events. With 95% event-free surgeries in the decolonization arm versus 90% in the control arm, we formally need 2 × 474 elective orthopedic surgeries included during 2 years.DiscussionIn selected adult orthopedic patients with a high risk for SSI, the presurgical decolonization may reduce postoperative wound problems, including SSI.Trial registrationClinicalTrial.gov NCT05647252. Registered on 9 December 2022.Protocol version: 2 (5 December 2022).

Comparison of thrombodynamic methods and routine hemostasis tests in the evaluation of hypercoagulable syndrome in chronic glomerulonephritis

Nephrotic syndrome (NS) is associated with a high risk of thrombotic complications. In this group of patients, routine local tests for assessing hemostasis do not accurately reflect hypercoagulable state. Global functional tests for assessing hemostasis, including thrombodynamics (TD), are considered promising for assessing disorders in the blood coagulation system of these patients. To compare the rate of hypercoagulability according to routine hemostatic tests and TD and to evaluate the factors associated with increased risk of thrombotic complications in patients with chronic glomerulonephritis (CGN). The study included 94 patients with active CGN who were not receiving anticoagulant therapy; 63 (80.3%) patients had NS, and 31 (19.7%) had active CGN without NS. Hemostasis parameters were assessed using local coagulation tests and TD test. Using logistic regression analysis, factors associated with the risk of thrombosis were assessed. Of the 94 patients with active CGN in 63 without preventive anticoagulant therapy, hypercoagulability according to routine tests was detected in 6 (9.5%) patients with NS and in 3 (9.7%) patients without NS (p<0.05). Hypercoagulability according to the TD test was detected in 24 (53.9%) patients with NS and in 5 (32.2%) without NS (p<0.05). The formation of spontaneous clots was observed in 29 (30.9%) of patients with CGN, most of them 24 (83%) with NS. 10.6% of patients in our cohort experienced thromboembolic events. The risk of thromboembolic events according to the univariate regression analysis was associated with older age, higher lipid levels, use of glucocorticosteroids and detection of spontaneous clots by the TD test. No association of thromboembolic events with abnormalities in routine hemostasis tests was obtained. In patients with CGN with nephrotic syndrome, hypercoagulability is detected in 9.5% of cases with routine coagulation tests and in 53.9% of cases with TD test. Detection of spontaneous clots by TD test is associated with a risk of thromboembolic events.

Association between surgical delays for femoral neck fractures and early postoperative complications in young and middle-aged adults: A study based on the national inpatient sample database

BackgroundFemoral neck fractures (FNF) in young and middle-aged adults are primarily caused by high-energy injuries in traffic accidents. Surgical delays often occur due to transportation issues, preoperative evaluations, and economic burdens. MethodsA retrospective analysis was conducted on young and middle-aged FNF patients undergoing reduction and internal fixation surgeries from 2010 to 2019 with the use of the National Inpatient Sample database. Logistic regression analysis was used to assess the relationship between surgical delays and complications, and the independent risk factors contributing to delays. Categorical variables were investigated via a chi-square test, while continuous variables including Elixhauser Comorbidity Index (ECI) scores, length of hospital stay (LOS), and total medical costs were analyzed via t-test or rank-sum test. Results9,204 patients undergoing reduction and internal fixation surgeries were included. In the delayed group, patients had higher ECI scores, longer hospital stays, higher expenses, and increased inpatient mortality (1.61% vs. 0.28 %, P < 0.0001). Longer surgical delays were associated with higher risks of complications, including femoral head osteonecrosis, internal fixation loosening and breakage, and respiratory complications. Fluid and electrolyte disorders, metastatic cancer, pulmonary circulation disorders, and renal failure were identified as independent risk factors for surgical delays. Except for anemia (OR=2.37, P < 0.0001), no significant differences in early postoperative complications were found between open-reduction and closed-reduction internal fixation (ORIF/CRIF) surgeries. ConclusionEarly surgical intervention, within a 2-days period after injury, seems to be crucial for young adults with FNF. If CRIF is challenging in some cases, ORIF can be another choice.

Primary hyperparathyroidism in pregnancy after in vitro fertilization

Primary hyperparathyroidism (PHPT) in pregnant women is a rare condition, often remaining undiagnosed due to non-specific clinical symptoms. However, it can lead to life-threatening complications for both the mother and fetus. In vitro fertilization (IVF) is also associated with an increased probability of adverse outcomes compared to the general population. Timely diagnostics and personalized treatment, taking into account the extremely high risk of complications if PHPT and pregnancy result from IVF, require attention of healthcare professionals and formation of a multidisciplinary team.
