Early acute kidney injury in sepsis and septic shock

ABSTRACT Background: Acute kidney injury is one of the severe conditions in hospitalized patients. Acute kidney injury can develop early from admission, usually within the first 24 hours of ICU admission. In Vietnam, there have been limited studies monitoring the progression of acute kidney injury in the early stages. This study aims to investigate the incidence, severity, clinical, laboratory characteristics, and progression of acute kidney injury in patients with sepsis and septic shock within the first 48 hours. Methods: This study is a cross-sectional descriptive analysis of 101 patients who are 15 or older and have been diagnosed with severe infection and septic shock. These patients were treated in the Intensive Care Unit of Hue Central Hospital. The patient had treatment in accordance with a standardized protocol while being closely observed. Samples were collected for diagnostic testing, and the patient’s urine output and blood creatinine levels were diligently checked. Results: The prevalence of acute renal injury (AKI) was 60.40%, with stage 1 accounting for 50.82% of cases, stage 2 accounting for 22.95%, and stage 3 accounting for 26.23%. The cohort of individuals diagnosed with AKI exhibited an advanced age, with a mean age of 60.72 ± 17.41 years, and predominantly consisted of male subjects. Patients diagnosed with acute kidney injury showed a statistically significant decrease in urine output and an increased incidence of shock (p < 0.05). Additionally, these patients demonstrated lower levels of Hct, blood pH, and bicarbonate while exhibiting higher levels of blood urea, blood creatinine, AST, ALT, total bilirubin, PCT, and blood lactate (p < 0.05) compared to individuals without AKI. Patients with AKI had significantly elevated SOFA and APACHE II scores compared to individuals without AKI, as indicated by statistical analysis (p < 0.05). Upon admission, a significant proportion of patients, precisely 81.97%, experienced the development of AKI. Furthermore, a observation was made about the prompt recovery of these patients within the initial 24 and 48 hours following admission. Conclusion: The prevalence of AKI was accounted for 60.40%. Among the cases of AKI, stage 1 accounted for 50.82%, while stage 2 and stage 3 accounted for 22.95% and 26.23%, respectively. There were observed variations in urine output and rates of shock among individuals diagnosed with AKI. Additionally, SOFA and APACHE II scores were elevated. The percentage of AKI was 81.97% of patients upon their initial hospital admission, with a significant proportion seeing early recovery within the first 24 to 48 hours.

Epidemiology of Injury and Illness in North American Professional Men's Soccer: Comparing COVID-19 Lockdown With Previous Seasons.

After COVID-19 lockdown, studies across Europe and Asia examined its effect on professional soccer injury rates and severity; however, COVID-19 lockdown influence on injuries in United States men's professional soccer has not been evaluated. Injury and illness rates during the 2020 season were higher than the previous 2 seasons. Retrospective observational cohort study. Level 3. Medical staff from participating Major League Soccer (MLS) clubs entered injuries and athletic exposures during the study period into a league-wide electronic medical record system. Injury rate and severity were analyzed to examine differentials between the 2020 COVID season and historical controls. The injury incidence rate per 1000 hours in 2020 was 10.8, ie, higher than 2018 (5.4) and 2019 (5.0) (P < 0.05). Training injury incidence rate increased in 2020 (8.9) compared with 2018 (2.5) and 2019 (2.6) (P < 0.05), whereas match injury incidence decreased in 2020 (18.3) compared with 2018 (24.0) and 2019 (22.7) (P < 0.05). Incidence rates of lower extremity muscle injuries (6.04), anterior cruciate ligament (ACL) injuries (0.17), and concussions (0.49) were also higher in 2020 compared with 2018 (2.5, 0.07, 0.27) and 2019 (2.36, 0.05, 0.22) (P < 0.05). More injured players in 2020 missed >90 days (17.7%) than in 2018 (10.2%) and 2019 (10.1%) (P < 0.05). Incidence of all non-COVID-19 illness was higher in 2020 (3.93) than 2018 (1.53) and 2019 (1.32) (P < 0.05). During 2020, there were significant increases in incidence rates of overall injuries, training injuries, lower extremity muscular injuries, ACL injuries, concussions, and non-COVID illness, along with a higher percentage of players missing >90 days compared with the 2 previous seasons. These results may help clarify the effects of future MLS inseason work stoppages and periods of restricted training.

Trends in severity of work-related traumatic injury and musculoskeletal disorder, Ontario 2004-2017.

Traumatic injury surveillance can be enhanced by describing injury severity trends. This study reports trends in work-related injury severity for males and females over the period 2004-2017 in Ontario, Canada. A weighted measure of workers' compensation benefit expenditures was used to define injury severity, obtained from the linkage of workers' compensation claims to emergency department (ED) records where the main injury or illness was attributed to work. Denominator counts were obtained from Statistics Canada's Labor Force Survey. Trends in the annual incidence of injury, classified as low, moderate, or high severity, were examined using regression modeling, stratified by age and sex. Over a 14-year observation period, there were 1,636,866 ED records included in the analyses. Overall, 57.6% of occupational injury records were classified as low severity, 29.5% as moderate severity, and 12.8% as high severity conditions. There was an increase in the incidence of high severity injuries among females (annual percent change (APC): 1.52%; 95% CI: 0.77, 2.28), while the incidence of low and moderate severity injuries generally declined for males and females. Among females, injuries attributed to animate mechanical forces and assault increased as causes of low, moderate, and high severity injuries. The incidence of concussion increased for both males (APC: 10.51%; 95% CI: 8.18, 12.88) and females (APC: 16.37%; 95% CI: 13.37, 19.45). The incidence of severe work-related injuries increased among females in Ontario between 2004 and 2017. The methods applied in this surveillance study of traumatic injury severity are plausibly generalizable to applications in other jurisdictions.

The presence of a deep lateral femoral notch sign in ACL-injured patients is associated with a 2.7° steeper posterior tibial slope and a 19% higher frequency of lateral meniscal injuries.

The purpose of this study was to study the relationship between the presence of a deep lateral femoral notch sign (DLFNS) in anterior cruciate ligament (ACL)-injured patients and a higher posterior lateral tibial slope (LPTS), a reduced meniscal bone angle (MBA), a higher LPTS/MBA ratio and a higher incidence of concomitant injuries in primary ACL tears. A retrospective case-control study was performed in patients submitted to primary ACL reconstruction with an available preoperative magnetic resonance imaging (MRI) scan. Patients with ACL tears and a femoral impactation with a depth ≥2 mm were assorted to the DLFNS groupand patients with ACL tear and without a DLFNS to the control group. LPTS and MBA were measured in MRI. The presence of concomitant injuries (meniscal, posterior cruciate ligament, medial collateral ligament, lateral collateral ligament and bone injuries) was assessed in MRI. Quantitative data are presented in the median ± interquartile range (IQR). There were 206 patients included in the study, with 46 patients assorted to the DLFNS group and 160 patients to the control group. In the DLFNS group, the median LPTS was 6.7° (IQR: 4.0-8.2) versus 4.0° in the control group (IQR: 2.2-6.5) (p = 0.003). The LPTS/MBA ratio was significantly higher in the DLFNS group, with a median of 0.32 (IQR: 0.19-0.44), in comparison to the control group, with a median of 0.19 (IQR: 0.11-0.31) (p < 0.001). The multivariable logistic regression analysis showed that the LPTS is an independent risk factor to having a DLFNS (odds ratio [OR] = 1.161; 95% confidence interval [CI]: 1.042-1.293, p = 0.007). There was a higher incidence of concomitant lateral meniscal injuries in the DLFNS group (67% vs. 48%, p = 0.017). In patients with ACL tears, the presence of a DLFNS is associated with a steeper lateral posterior tibial slope, as well as a higher incidence of concomitant lateral meniscal injuries. Level III.

Hemadsorption to Contain Postoperative Cell-Free Hemoglobin and Haptoglobin Preservation for Extended Cardiopulmonary Bypass Time in Cardiac Surgery for Acute Kidney Injuries Prevention.

Prevention of acute kidney injury during cardiopulmonary bypass (CPB) is still a challenge and has been the object of numerous studies. The incidence of acute kidney injury in the context of CPB is related to a multifactorial etiology. The role of hemadsorption in relation to cell-free hemoglobin and haptoglobin preservation is not well defined in the literature on CPB during cardiac surgery procedures. This is a single-center pilot randomized report including 20 patients undergoing elective CPB procedures with an expected time > 120 minutes for each extracorporeal procedure. Patients were randomly allocated to either standard of care (n=10) or Jafron HA380 (n=10) during CPB. The primary outcome measured was the incidence of postoperative acute kidney injuries. The Jafron study group vs. control group reported postoperative values for cell-free hemoglobin at 10 minutes after CPB (mg/L) (11.6 ± 0.6 vs. 29.9 ± 0.3) (P-value 0.021), haptoglobin 10 minutes after CPB (mg/dl) (129.16 ± 1.22 vs. 59.17 ± 1.49) (P-value 0.017), creatinine peak after CPB (mg/dL) (0.92 ± 0.17 vs. 1.32 ± 0.9) (P-value 0.030), and acute kidney injury after 48 hours (number of patients) (one vs. four) (P-value 0.027). This pilot study suggested that the use of Hemoperfusion Cartridge HA380 Jafron for extended CPB time for complex cardiac surgery procedures was safe and effective and is associated with a better postoperative preservation of haptoglobin with a reduction of cell-free hemoglobin values and less incidence of acute kidney injury, though larger studies are warranted to confirm our result.

Predicting severe intraventricular hemorrhage or early death using machine learning algorithms in VLBWI of the Korean Neonatal Network Database

Severe intraventricular hemorrhage (IVH) in premature infants can lead to serious neurological complications. This retrospective cohort study used the Korean Neonatal Network (KNN) dataset to develop prediction models for severe IVH or early death in very-low-birth-weight infants (VLBWIs) using machine-learning algorithms. The study included VLBWIs registered in the KNN database. The outcome was the diagnosis of IVH Grades 3–4 or death within one week of birth. Predictors were categorized into three groups based on their observed stage during the perinatal period. The dataset was divided into derivation and validation sets at an 8:2 ratio. Models were built using Logistic Regression with Ridge Regulation (LR), Random Forest, and eXtreme Gradient Boosting (XGB). Stage 1 models, based on predictors observed before birth, exhibited similar performance. Stage 2 models, based on predictors observed up to one hour after birth, showed improved performance in all models compared to Stage 1 models. Stage 3 models, based on predictors observed up to one week after birth, showed the best performance, particularly in the XGB model. Its integration into treatment and management protocols can potentially reduce the incidence of permanent brain injury caused by IVH during the early stages of birth.

The association between waterbirth and perineal injury or other adverse outcomes among low-risk women with physiological birth: Results from the Nordic Home Birth Cohort Study

Problem/backgroundImmersion in water has known benefits, such as reducing pain and shortening the duration of labour. The relationship between waterbirth and perineal injury remains unclear. AimTo compare the incidence of perineal injury in waterbirth and birth on land among low-risk women. Secondary outcomes were postpartum haemorrhage and 5-minute Apgar scores <7. MethodsProspective cohort study of 2875 low-risk women who planned a home birth in Denmark, Iceland, Norway, and Sweden in 2008–2013 and had a spontaneous vaginal birth without intervention. Descriptive statistics and logistic regression were performed. FindingsA total of 942 women had a waterbirth, and 1933 gave birth on land. The groups differed in their various background variables. Multiparous women had moderately lower rates of intact perineum (59.3% vs. 63.9%) and primiparous women had lower rates of episiotomies (1.1% vs. 4.8%) in waterbirth than in birth on land. No statistically significant differences were detected in adjusted regression analysis on intact perineum in waterbirth (primiparous women’s aOR = 1.03, CI 0.68–1.58; multiparous women’s aOR = 0.84, CI 0.67–1.05). The rates of sphincter injuries (0.9% vs. 0.6%) were low in both groups. No significant differences were detected in secondary outcomes. DiscussionThe decreased incidence of intact perineum among multiparous women was modest and inconclusive, and the prevalence of sphincter injury was low. ConclusionLow-risk women contemplating waterbirth should be advised to weigh the risks and benefits detected in this study against previously established benefits of waterbirth and should make an informed choice based on their values.

Low blood glucose and fatigue accumulation at peak hours of occupational trauma in secondary industry workers

Objectives. The incidence of occupational traumatic injuries caused by human error has been reported to occur at 11:00 and 8–9 h after commencing work. Impaired attention is closely related to the incidence of these accidents. Therefore, this study aimed to clarify the changes in blood glucose, fatigue and stress response hormone levels over time among workers in a secondary industry. Methods. The blood glucose and subjective fatigue levels of 26 male secondary-industry workers were measured on workdays. In addition, the cortisol and dehydroepiandrosterone levels in saliva were measured on one workday and one holiday. Results. Blood glucose levels at 11:00 and 17:30 on the workday were significantly lower than those at 09:30. Moreover, hypoglycemia was observed in some participants. A significant increase in subjective fatigue levels was observed during the workday. However, no significant differences in salivary cortisol levels were observed between the workday and the holiday at any time point. Conclusions. Blood glucose levels decreased and subjective fatigue levels increased at the time points that occupational accidents were reported to occur most frequently during work. These factors may contribute to human errors due to impaired attentional function.

Effect of a fall within three months of admission on delirium in critically Ill elderly patients: a population-based cohort study

BackgroundDelirium is common among elderly patients in the intensive care unit (ICU) and is associated with prolonged hospitalization, increased healthcare costs, and increased risk of death. Understanding the potential risk factors and early prevention of delirium is critical to facilitate timely intervention that may reverse or mitigate the harmful consequences of delirium.AimTo clarify the effects of pre-admission falls on ICU outcomes, primarily delirium, and secondarily pressure injuries and urinary tract infections. MethodsThe study relied on data sourced from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Statistical tests (Wilcoxon rank-sum or chi-squared) compared cohort characteristics. Logistic regression was employed to investigate the association between a history of falls and delirium, as well as secondary outcomes, while Kaplan–Meier survival curves were used to assess short-term survival in delirium and non-delirium patients.ResultsStudy encompassed 22,547 participants. Delirium incidence was 40%, significantly higher in patients with a history of falls (54.4% vs. 34.5%, p < 0.001). Logistic regression, controlling for confounders, not only confirmed that a history of falls elevates the odds of delirium (OR: 2.11; 95% CI: 1.97–2.26; p < 0.001) but also showed it increases the incidence of urinary tract infections (OR:1.50; 95% CI:1.40–1.62; p < 0.001) and pressure injuries (OR:1.36; 95% CI:1.26–1.47; p < 0.001). Elderly delirium patients exhibited lower 30-, 180-, and 360-day survival rates than non-delirium counterparts (all p < 0.001).ConclusionsThe study reveals that history of falls significantly heighten the risk of delirium and other adverse outcomes in elderly ICU patients, leading to decreased short-term survival rates. This emphasizes the critical need for early interventions and could inform future strategies to manage and prevent these conditions in ICU settings.

Recent progress in neonatal hyperoxic lung injury.

With the progress in neonatal intensive care, there has been an increase in the survival rates of premature infants. However, this has also led to an increased incidence of neonatal hyperoxia lung injury and bronchopulmonary dysplasia (BPD), whose pathogenesis is believed to be influenced by various prenatal and postnatal factors, although the exact mechanisms remain unclear. Recent studies suggest that multiple mechanisms might be involved in neonatal hyperoxic lung injury and BPD, with sex also possibly playing an important role, and numerous drugs have been proposed and shown promise for improving the treatment outcomes of hyperoxic lung injury. Therefore, this paper aims to analyze and summarize sex differences in neonatal hyperoxic lung injury, potential pathogenesis and treatment progress to provide new ideas for basic and clinical research in this field.

The Association Between Grip Strength, Upper Body Power, and Limb Dominance in a Military Population.

Military service members rely on upper body strength and power to accomplish tasks such as carrying heavy weapons and gear, rappelling, combat grappling, and marksmanship. Early identification of the factors that lead to reduced upper body strength and power would enable leadership to predict and mitigate aspects that decrease military operational readiness and increase injury risk. The purpose of this study was to investigate the relationship between grip strength and upper body power in U.S. Infantry Marines. We hypothesized that dominant arm grip strength would show a strong positive correlation with upper body power and that the dominant arm would be more powerful than the non-dominant arm. A total of 120 U.S. Marines completed 3 maximum effort isometric grip strength trials with their dominant hand and 3 maximum effort ballistic pushups on a ForceDecks force plate system. Force plate data were used to estimate pushup height and peak power. Maximum grip strength, pushup height, and peak power across the 3 trials were used for analysis. Pearson's correlation was used to test for associations between peak power, pushup height, and grip strength. Paired t-tests were used to test for differences in peak power between the dominant and non-dominant arms. A very weak correlation was found between grip strength and upper body power, but there was no relationship between grip strength and pushup height. Additionally, there were no significant differences in upper body power between the dominant and non-dominant arms. The results of this study suggest that grip strength is not predictive of upper body power and cannot be used as a stand-alone measure of physical readiness in a military unit. These findings do not, however, degrade the potential of both measures to predict and inform health status and physical readiness. Future prospective research should be conducted to determine if either of these measures can be used as indicators of performance and/or injury susceptibility and if limb dominance plays a role in injury incidence within the upper extremity.

Nervous system functioning disorders in patients with mandible fractures

Relevance. Fractures of the mandibular fracture are a stressor on the body and lead to changes in the functioning of the autonomic nervous system. At the same time, patients with mandibular fractures often experience local changes in the nervous system associated with the anatomical and physiological features of the location of the third branch of the trigeminal nerve and its damage. These changes affect the course of the post-traumatic period and may increase the likelihood of complications of mandibular fractures.Purpose: to determine the significance of disturbances in the functioning of the nervous system during the post-traumatic period of fractures of the mandibular fracture.Materials and methods. When examining 130 patients with fractures of the mandibular fracture, the state of the autonomic nervous system and local neurological changes were studied.Results. In patients with mandibular fractures, dysfunction of the autonomic (autonomic) nervous system and local neurological changes were revealed.The severity of these changes is reflected in the development of complications of fractures. When studying the autonomic nervous system in patients with mandibular fractures, there was an increase in the activity of the sympathetic nervous system, which increased the likelihood of developing complications of mandibular fractures. A high incidence of injury to the inferior alveolar nerve was also found. The most pronounced deviations in autonomic balance indicators – pathological increased excitability of the autonomic nervous system – were diagnosed in patients with complicated fractures of the mandibular fractures. In most patients with complicated mandibular fractures, damage to the trigeminal nerve was detected, confirming the role of neurotrophic disorders in the development of complications.Conclusion. With fractures of the mandible, there is an increase in the activity of the sympathetic nervous system, which increases the likelihood of complications. The most pronounced deviations in autonomic balance indicators were diagnosed in patients with complicated fractures of the mandible. In addition, in patients with mandibular fractures, a high incidence of damage to the inferior alveolar nerve was revealed; in complicated fractures, neuropathy is severe, which confirms the role of neurotrophic disorders in the development of complications. Thus, methods for preventing purulent-inflammatory complications in jaw fractures should include correction of neurological disorders.

A Prospective Study of Incidence, Risk Factors, and Outcomes of Acute Kidney Injury in Coronavirus Disease 2019

Background: Acute kidney injury (AKI) is common after coronavirus 2 infection (COVID-19), leading to higher morbidity and mortality. There is little prospective data from India regarding the incidence, risk factors, and outcome of AKI in COVID-19. Materials and Methods: This study was conducted prospectively in adult patients between September and December 2020 in a tertiary care hospital in the national capital region of Delhi. A total of 856 patients with COVID-19 infection were enrolled in the study. Survivors were followed for 3 months after discharge. Results: Out of 856 patients, 207 (24%) developed AKI. AKI was significantly higher in those with severe disease as compared to mild-moderate disease (88% vs. 12%, P = 0.04). Out of all AKI, 3.4% had stage 1, 9.2% had stage 2, and the rest 87.4% had stage 3 AKI. 183/207 (88%) patients were on mechanical ventilators, 133 (64%) required inotropic support, and 137/207 (83.6%) patients required kidney replacement therapy. Out of 207 AKI patients, 74% (153) died as compared to 4% (27) in non-AKI group (P = 0.0001). After 3 months, chronic kidney disease (CKD) developed in 10/54 (18.5%) patients. On multivariable analysis, the presence of diabetes mellitus, severe COVID-19 disease, high levels of C reactive protein, lactate dehydrogenase, D-Dimer, and use of intravenous steroids, tocilizumab and remdesivir, were found to be significant predictors of AKI. Conclusion: AKI is common after COVID-19 infection and it is a significant risk factor for mortality in COVID-19. Patients with diabetes and high levels of inflammatory markers have higher mortality. CKD may develop in many patients after discharge.

Comparison of Liver Injury in Patients Taking Methotrexate and Leflunamide in Rheumatoid Arthritis

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the joints, leading to inflammation and potential joint damage. Methotrexate (MTX) and Leflunomide (LEF) are commonly used disease-modifying antirheumatic drugs (DMARDs) for RA, but their hepatotoxic effects require careful monitoring. Objective: This study aimed to compare the incidence of liver injury in RA patients treated with Methotrexate versus Leflunomide. Methods: This prospective study was conducted from January 2023 to June 2023 and included 80 RA patients aged 20 years or older, who reported to the Medicine Department at Combined Military Hospital (CMH) Lahore. Patients were divided into two groups: Group A received 20 mg/day Methotrexate (n=40), and Group B received 20 mg/day Leflunomide (n=40). Exclusion criteria included pregnant females, patients with hepatitis B or C, those with known allergies to Methotrexate or Leflunomide, and alcoholics. Baseline investigations, including liver enzyme levels (ALT/AST), were performed, and patients were monitored every three months. Hepatotoxicity was defined as an increase in ALT/AST levels to at least twice the upper limit of normal (ULN). Data were analyzed using SPSS version 25.0, with mean and standard deviation for quantitative data and frequency and percentage for qualitative data. The Chi-square test was used to compare variables, with p&lt;0.05 considered statistically significant. Results: Out of 80 patients, 43 (53.75%) were female, and 37 (46.25%) were male. In Group A, 7 patients (17.5%) had elevated ALT/AST levels, while 6 patients (15%) in Group B exhibited elevated liver enzymes. The mean age was 52.4 ± 8.3 years in Group A and 50.6 ± 9.1 years in Group B. The mean BMI was 26.7 ± 3.5 kg/m² in Group A and 27.1 ± 3.8 kg/m² in Group B. No statistically significant difference in hepatotoxicity was observed between the two groups (p&gt;0.05). Conclusion: Methotrexate and Leflunomide were equally effective in treating RA, with no significant difference in liver toxicity observed between the two groups. Both medications have comparable risks for hepatotoxicity, necessitating regular liver function monitoring during treatment.

The Jarring Reality: Adolescent and Pediatric Gunshot Trauma on the Rise in a Major Urban Institution.

Firearms are the leading cause of death in the pediatric population, and the incidence of firearm injury is on the rise in the United States. The purpose of this study was to examine the incidence of pediatric gunshot wounds (GSWs) in New Orleans from 2012 to 2023 and evaluate factors that contribute to mortality. A retrospective analysis of pediatric GSWs was conducted using the trauma database at a Level I trauma center in New Orleans, Louisiana. All patients aged 0 to 18 years with a GSW between January 1, 2012, and January 1, 2023, were evaluated. Demographic data, Injury Severity Score (ISS), hospital length of stay (LOS), discharge disposition, intent of injury, mortality, firearm type, orthopaedic injuries, and related surgical procedures were extracted from the database. Linear regression was used to assess the trend of GSWs over time, and logistic regression was used to identify variables that predicted mortality. Statistical significance was defined as α = 0.05. Geographic information system (GIS) mapping was conducted using the ZIP code location of injury to identify geographic areas with the greatest number of GSWs. A significant increasing trend was observed in the number of pediatric GSWs when adjusted for changes in population (P = 0.014), and the number of GSWs increased 43.2% over the duration of the study. Higher ISS, shorter length of stay, and self-inflicted intent of injury were notable predictors of mortality. Three hundred fifty-four patients (31.4%) had at least one orthopaedic injury, and of the survivors, 365 patients (35.6%) required at least one surgical procedure in the operating room during their admission. The number of GSWs in the pediatric population in New Orleans presenting at a large level 1 trauma center demonstrated a statistically significant increasing trend over the past 11 years. ISS and self-inflicted intent were predictive of mortality within this pediatric patient population.

Risk factors for acute kidney injury and kidney relapse in patients with lupus podocytopathy

Abstract Background Patients with lupus podocytopathy show a high incidence of acute kidney injury (AKI) and relapse, but the risk factors and mechanisms were unclear. This study analyzed the clinical-pathological features, and risk factors for AKI and relapse in lupus podocytopathy patients. Methods The cohort of lupus podocytopathy was generated by screening the biopsies of patients with lupus nephritis (LN) from 2002 to 2022, and was divided into the mild glomerular lesion (MGL) and FSGS groups based on glomerular morphological characteristics. The acute (ATI) and chronic (CTI) tubulointerstitial lesions were semi-quantitatively scored. Logistic and Cox regression was employed to identify the risk factors for AKI and relapse, respectively. Results Among 6 052 LN cases, 98 (1.6%) were diagnosed as lupus podocytopathy, with 71 in the MGL group and 27 in the FSGS group. All patients presented with nephrotic syndrome, and 33 (34.7%) of them had AKI. Seventy-seven (78.6%) patients achieved complete renal response (CRR) within 12 weeks of induction treatment, in which there was no difference in CRR rate between glucocorticoid monotherapy and combination therapy with glucocorticoids plus immunosuppressants. Compared to the MGL group, patients in the FSGS group had significantly higher incidences of hypertension and hematuria; in addition, they had higher SLEDAI-2 K, ATI and CTI scores, but a significantly lower CRR rate. Urinary protein ≥ 7.0 g/24 h and serum C3 ≤ 0.750 g/L were independent risk factors for AKI. During a median follow-up of 78 months, 57 cases (60.0%) had relapse, and none reached the kidney endpoint. Failure to achieve CRR within 12 weeks, maintenance with glucocorticoid monotherapy and AKI at onset were independent risk factors for the kidney relapse. Conclusions In this study, histological subtypes of lupus podocytopathy are found to be associated with clinical feature and treatment response;in addition, several risk factors associated with AKI occurrence and kidney relapse are identified.

Evaluating Fibular Intramedullary Nails vs Traditional Plating in Geriatric Ankle Fractures: A 12-Year Single-Center Retrospective Study

Background: This study evaluates the outcomes of fibular intramedullary nails (IMNs) compared to traditional plates and screws (PS) in the surgical treatment of unstable ankle injuries in patients aged ≥65 years. Method: We conducted a retrospective study involving 32 elderly patients with unstable ankle fractures treated with IMNs from 2010 to 2022. A comparison was made with 125 case-control patients treated with PS during the same period. Outcomes compared included postoperative wound and nonwound complications, surgical reduction, union rates, implant removal rates, and the Olerud Molander Ankle Score (OMAS) at a minimum follow-up of 2 years. Results: The IMN group had a higher incidence of high-energy injuries, open fractures, concomitant surgery, and perioperative transfusion requirements than the PS group. Additionally, the IMN group developed fewer wound-related (3.1% vs 20% in the PS group, P = .043) and non–wound-related complications (18.8% vs 39.2% in the PS group, P = .030). Both groups had similar initial weightbearing restrictions, fracture union times, mean OMAS scores, rates of malunion or nonunion, and delayed implant removal times. Notably, there were significant differences in the quality and adequacy of mortise alignment between the groups (good: 53.1% in IMN group vs 79.2% in PS group, fair: 46.9% in IMN group vs 20.8% in PS group, P = .006). Conclusion: Although the IMN group had an inferior outcome in the quality and adequacy of mortise reduction compared with the PS group, elderly patients with ankle fractures treated with IMN showed comparable functional outcomes to those treated with PS but with lower complication rates. Future research in this area will provide vital information for developing optimal treatment strategies, thereby improving the overall care of elderly patients with ankle fractures. Level of Evidence: Level III, case-control study.

Data-driven automatic classification model for construction accident cases using natural language processing with hyperparameter tuning

The construction industry, while vital to societal progress, is marred by a high incidence of accidents and injuries. Manual classification of accident cases is intensive and susceptible to human bias. This study addresses this challenge by developing an automated accident case classification system for the construction industry using Natural Language Processing and machine learning techniques. This study was conducted using the following steps: (1) Establishment of dataset (2) Korean Natural Language Processing (3) Selection of machine learning models (4) Model evaluation. The models exhibited competitive performance, demonstrating high accuracy, precision, and recall rates across all classification tasks.

Association between hydroxyethyl starch 130/0.4 administration during noncardiac surgery and postoperative acute kidney injury: A propensity score-matched analysis of a large cohort in China

Study objectiveThe use of hydroxyethyl starch 130/0.4 has been linked to renal injury in critically ill patients, but its impact on surgical patients remains uncertain. DesignA retrospective cohort study. SettingThis study was conducted at one tertiary care hospital in China. PatientsWe evaluated the records of 51,926 Chinese adults who underwent noncardiac surgery from 2013 to 2022. Patients given a combination of hydroxyethyl starch 130/0.4 and crystalloids were propensity-matched at a 1: 1 ratio of baseline characteristics to patients given only crystalloids (11,725 pairs). InterventionsEligible patients were divided into those given a combination of hydroxyethyl starch 130/0.4 and crystalloid during surgery and a reference crystalloid group consisting of patients who were not given any colloid. MeasurementsThe primary outcome was the incidence of acute kidney injury. Secondarily, acute kidney injury stage, need for renal replacement therapy, intensive care unit transfer rate, and duration of postoperative hospitalization were considered. Main resultsAfter matching, hydroxyethyl starch use [8.5 (IQR: 7.5–10.0) mL/kg] did not increase the incidence of acute kidney injury compared with that in the crystalloid group [2.0 vs. 2.2%, OR: 0.90 (0.74–1.08), P = 0.25]. Nor did hydroxyethyl starch use worsen acute kidney injury stage [OR 0.90 (0.75–1.08), P = 0.26]. No significant differences between the fluid groups were observed in renal replacement therapy [OR 0.60 (0.41–0.90), P = 0.02)] or intensive care unit transfers [OR 1.02 (0.95–1.09), P = 0.53] after Bonferroni correction. Even in a subset of patients at high risk of renal injury, hydroxyethyl starch use was not associated with worse outcomes. ConclusionsHydroxyethyl starch 130/0.4 use was not significantly associated with a greater incidence of postoperative acute kidney injury compared to receiving crystalloid solutions only.
