The first time devastating food poisoning happened in Taiwan - Bongkrekic acid poisoning.

Bongkrekic acid (BKA), a rarely happened foodborne toxin by Burkholderia gladioli pathovar cocovenenans (Burkholderia cocovenenans) might leads to devastating life-threatening condition after eating meal contaminated BKA. Unbelievable event from March 19, 2024, to March 24, 2024, there was an outbreak of BAP in a luxury shopping area of eastern Taipei, Taiwan. Most of the victims are young to middle-aged people who made a tour over there and ate the cooked wet rice noodles. Of them, 13 males and 20 females, aged 40.9 ± 14.7 years old visited or were sent by ambulances to the emergency department presenting with watery diarrhea, and vomiting. Some progressed to severe hepatic and renal failure, altered mental status, disseminated intravascular coagulation, and fatalities within several hours within 2 days. The primary health workers especially emergency physicians need to keep in mind of BKA poisoning is quite different in presentations from other infectious colitis commonly seen before. Knowing the toxic-kinetic and toxic-dynamic mechanisms is important to farseeing the presentation of these BAP patients. Throughout this outbreak, we gathered abundant experiences in mitigating and managing these debilitated patients. Aggressively supportive care and early liver transplantation if there is no concurrent inflammatory process and the patient's condition is tolerable to surgical intervention saves lives. For food safety education, it is crucial to enhance our understanding of inhibiting BKA production and promote proper food preservation methods and a suitable environment to ensure food safety.

A Case Report of Hemophagocytic Lymphohistiocytosis Masquerading as Sepsis.

Profound inflammation due to cytokine storm is often the underlying cause of death in patients with hemophagocytic lymphohistiocytosis (HLH). Sepsis, while a precipitant, is also the great masquerader that may hide early signs of HLH. Prompt recognition is important to prevent rapid clinical decline and death. A patient presented with two weeks of unremitting fever of 103°F, dysuria, bilateral flank pain, and confusion. Obstructive uropathy and pyelonephritis were treated with a Foley catheter and antibiotics. There were abnormal developments during his hospitalization including a deep vein thrombus despite prophylactic anticoagulation. Antibiotics and Foley management did not improve fevers or renal injury so he eventually required continuous renal replacement therapy and blood product transfusions. In rapid progression, the patient developed pancytopenia, neutropenia, hyperferritinemia, hypertriglyceridemia, and hypofibrinogenemia suspicious for HLH. A bone marrow biopsy was consistent with progressive T-cell lymphoma, the likely cause of secondary HLH. Antineoplastics, corticosteroids, and opportunistic prophylaxis were pursued. Unfortunately, the cytopenias worsened, and the patient developed shock with hypoxemia and hypotension, followed by cardiac arrest and demise.

A case report of metformin-associated lactic acidosis.

Key Clinical Message: Metformin-associated lactic acidosis is a rare but serious complication in patients with type 2 diabetes, especially those with multiple health conditions. Prompt recognition and treatment, including potential renal replacement therapy, are crucial for managing severe acidosis and improving patient outcomes. Abstract: Metformin (MTF) is commonly prescribed as a first-line treatment for diabetes, effectively preventing microvascular and macrovascular complications. However, metformin-associated lactic acidosis is a rare yet severe complication, associated with a mortality rate of up to 50%. We encountered a case involving a 73-year-old woman with type 2 diabetes, mental illness, and hypothyroidism, who developed life-threatening lactic acidosis while on metformin therapy. Upon presenting to the emergency department with complaints of weakness, nausea, and decreased urination for 5 days, she also reported abdominal pain and shortness of breath. Hypotension was noted with a blood pressure of 80/50 mmHg. Initial laboratory results revealed severe acidosis, prompting discontinuation of MTF. Despite resuscitation efforts and vasopressor therapy, severe acidemia persisted, leading to the initiation of renal replacement therapy. Following treatment with continuous renal replacement therapy, her acidemia resolved, and she was discharged from the hospital on the sixth day without complications, with normal kidney function.

Dual Dialysis for Post-bilateral Orthotopic Lung Transplantation Hyperammonemia.

Hyperammonemia is a metabolic disorder characterized by supraphysiologic ammonia (NH3) concentrations in the blood. Although usually seen in adults with liver disease, hyperammonemia is a notable complication in 4.1% of lung transplants. It is associated with cerebral edema and neurological dysfunction and carries up to 75% mortality in critically ill patients. Opportunistic infections caused by Mycoplasma and Ureaplasma species have been implicated as the cause of this metabolic disturbance. Literature in neonates has shown that renal replacement therapy (RRT) is the best choice for treating patients with neurologic manifestations of hyperammonemia, in cases of NH3 clearance than continuous renal replacement therapy (CRRT). In contrast, continuous venovenous hemodialysis (CVVHD) is usually better tolerated for patients with hemodynamic instability for NH3 clearance. NH3 is a small molecule whose clearance mirrors urea in dialysis. Even though RRT can be a treatment modality for hyperammonemia in adults and neonates, there is very little literature on adults. We present a unique case demonstrating improvement in neurologic manifestations of hyperammonemia by using both IHD and CVVHD in an adult patient.

Type B Lactic Acidosis Secondary to Metastatic Liver Cancer in the Setting of Normal Renal Function: A Case Report and Literature Review.

Lactic acidosis occurs from an overproduction of lactate or decreased metabolism. It is common in critically ill patients, especially those with hematological conditions such as multiple myeloma, leukemia, and lymphoma. There are two types of lactic acidosis, Type A and Type B, with Type B presenting more commonly in hematological conditions that require prompt diagnosis and treatment of the underlying condition. We present a case of a 43-year-old male with Type B lactic acidosis secondary to stage IV colon cancer with metastasis to the liver. Initial laboratory work was significant for lactic acid of 16.52 mmol/L. Arterial blood gas (ABG) showed pH 7.26, pCO2 21 mmHg, pO2 111 mmHg, and HCO3 9 mEq/L, revealing an anion gap and metabolic acidosis with compensatory respiratory alkalosis. Initially, the patient was treated with aggressive fluid management, IV antibiotics, and sodium bicarbonate; however, his lactic acid continued to rise. The recommendation was made for urgent dialysis. Despite treatments, the prognosis is poor.

Forecasting acute kidney injury and resource utilization in ICU patients using longitudinal, multimodal models.

BACKGROUND: Advances in artificial intelligence (AI) have realized the potential of revolutionizing healthcare, such as predicting disease progression via longitudinal inspection of Electronic Health Records (EHRs) and lab tests from patients admitted to Intensive Care Units (ICU). Although substantial literature exists addressing broad subjects, including the prediction of mortality, length-of-stay, and readmission, studies focusing on forecasting Acute Kidney Injury (AKI), specifically dialysis anticipation like Continuous Renal Replacement Therapy (CRRT) are scarce. The technicality of how to implement AI remains elusive. OBJECTIVE: This study aims to elucidate the important factors and methods that are required to develop effective predictive models of AKI and CRRT for patients admitted to ICU, using EHRs in the Medical Information Mart for Intensive Care (MIMIC) database. METHODS: We conducted a comprehensive comparative analysis of established predictive models, considering both time-series measurements and clinical notes from MIMIC-IV databases. Subsequently, we proposed a novel multi-modal model which integrates embeddings of top-performing unimodal models, including Long Short-Term Memory (LSTM) and BioMedBERT, and leverages both unstructured clinical notes and structured time series measurements derived from EHRs to enable the early prediction of AKI and CRRT. RESULTS: Our multimodal model achieved a lead time of at least 12 h ahead of clinical manifestation, with an Area Under the Receiver Operating Characteristic Curve (AUROC) of 0.888 for AKI and 0.997 for CRRT, as well as an Area Under the Precision Recall Curve (AUPRC) of 0.727 for AKI and 0.840 for CRRT, respectively, which significantly outperformed the baseline models. Additionally, we performed a SHapley Additive exPlanation (SHAP) analysis using the expected gradients algorithm, which highlighted important, previously underappreciated predictive features for AKI and CRRT. CONCLUSION: Our study revealed the importance and the technicality of applying longitudinal, multimodal modeling to improve early prediction of AKI and CRRT, offering insights for timely interventions. The performance and interpretability of our model indicate its potential for further assessment towards clinical applications, to ultimately optimize AKI management and enhance patient outcomes.

Alcoholism and Immobility Induced Rhabdomyolysis Culminating in Hemodialysis.

Rhabdomyolysis is characterised by muscle breakdown and the release of myoglobin. It is a potentially serious condition that can lead to acute kidney injury (AKI). Factors, such as ischemia, trauma, muscle compression and drug toxicity, can trigger muscle breakdown. Treatment involves aggressive fluid resuscitation to maintain urine output and prevent renal injury. Severe cases with AKI may require temporary renal replacement therapy, such as haemodialysis. It has also been proposed that dialysis can speed up recovery by removing myoglobin that is secreted into the circulation by injured muscles. We present a case of a patient with alcohol abuse and prolonged immobility leading to severe rhabdomyolysis requiring hemodialysis. Our aim is to emphasise the importance of timely identification, and appropriate management of severe rhabdomyolysis not improving on fluids may require HD as soon as possible in order to minimise complications.

Clinical Outcomes of Trimethoprim/Sulfamethoxazole in Critically Ill Patients with Stenotrophomonas maltophilia Bacteremia and Pneumonia Utilizing Renal Replacement Therapies.

Background: The clinical outcomes of usual doses of Trimethoprim-sulfamethoxazole (TMP/SMZ) for treating S. maltophilia in critically ill patients on renal replacement therapies (RRT) have not been established. We sought to assess the clinical outcomes of TMP/SMZ in patients with sepsis utilizing RRT. Methods: A retrospective study was performed on all critically ill adult patients with S. maltophilia infections who received RRT between May 2015 and January 2022. The primary endpoint was clinical cure while the secondary endpoints were microbiologic cure, 30-day infection recurrence, and mortality. Results: Forty-five subjects met the inclusion criteria. The median age was 70.0 [interquartile range (IQR): 63.5-77] years, 57.8% were males, and the median body mass index was 25.7 [IQR: 22-30.2] kg/m2. Clinical success and failure were reported in 18 (40%) and 27 (60%) cases, respectively. There was no significant difference between the 30-day reinfection rates of both groups; however, mortality was significantly higher in the clinical failure group, involving 12 patients (44.4%), versus none in the clinical success group (p = 0.001). The median daily dose of TMP/SMZ upon continuous veno-venous hemofiltration was 1064 [IQR: 776-1380] mg in the clinical cure group vs. 768 [IQR:540-1200] mg in the clinical failure group (p = 0.035). Meanwhile, the median dose for those who received intermittent hemodialysis was 500 [IQR: 320-928] mg in the clinical success group compared to 640 [IQR: 360-1005] mg in the clinical failure group (p = 0.372). A total of 55% experienced thrombocytopenia, 42% hyperkalemia, and 2.2% neutropenia. The multivariable logistic regression analysis showed that the total daily dose at therapy initiation was the only independent factor associated with clinical success after adjusting for different variables including the body mass index [Odds ratio 1.004; 95% confidence interval: (1-1.007), p = 0.044]. Conclusions: Although the S. maltophilia isolates were reported as susceptible, TMP/SMZ with conventional doses to treat bacteremia and pneumonia in critically ill patients utilizing RRT was associated with high rates of clinical and microbiologic failure as well as with mortality. Larger outcomes and pharmacokinetics studies are needed to confirm our findings.

Initial renal replacement therapy (RRT) modality associates with 90-day postdischarge RRT dependence in critically ill AKI survivors.

PURPOSE: Real-world comparison of RRT modality on RRT dependence at 90 days postdischarge among ICU patients discharged alive after RRT for acute kidney injury (AKI). METHODS: Using claims-linked to US hospital discharge data (Premier PINC AI Healthcare Database [PHD]), we compared continuous renal replacement therapy (CRRT) vs. intermittent hemodialysis (IHD) for AKI in adult ICU patients discharged alive from January 1, 2018 to June 30, 2021. RRT dependence at 90 days postdischarge was defined as ≥2 RRT treatments in the last 8 days. Between-group differences were balanced using inverse probability treatment weighting (IPTW). RESULTS: Of 34,804 patients, 3804 patients (from 382 hospitals) had claims coverage for days 83-90 postdischarge. Compared to IHD-treated patients (n = 2740), CRRT-treated patients (n = 1064) were younger; had more admission to large teaching hospitals, surgery, sepsis, shock, mechanical ventilation, but lower prevalence of comorbidities (p < 0.05 for all). Compared to IHD-treated patients, CRRT-treated patients had lower RRT dependence at hospital discharge (26.5% vs. 29.8%, p = 0.04) and lower RRT dependence at 90 days postdischarge (4.9% vs. 7.4% p = 0.006) with weighted adjusted OR (95% CI): 0.68 (0.47-0.97), p = 0.03. Results persisted in sensitivity analyses including patients who died during days 1-90 postdischarge (n = 112) or excluding patients from hospitals with IHD patients only (n = 335), or when excluding patients who switched RRT modalities (n = 451). CONCLUSIONS: Adjusted for potential confounders, the odds of RRT dependence at 90 days postdischarge among survivors of RRT for AKI was 30% lower for those treated first with CRRT vs. IHD, overall and in several sensitivity analyses. SUMMARY: Critically ill patients in intensive care units (ICU) may develop acute kidney injury (AKI) that requires renal replacement therapy (RRT) to temporarily replace the injured kidney function of cleaning the blood. Two main types of RRT in the ICU are called continuous renal replacement therapy (CRRT), which is performed almost continuously, i.e., for >18 h per day, and intermittent hemodialysis (IHD), which is a more rapid RRT that is usually completed in a little bit over 6 h, several times per week. The slower CRRT may be gentler on the kidneys and is more likely to be used in the sickest patients, who may not be able to tolerate IHD. We conducted a data-analysis study to evaluate whether long-term effects on kidney function (assessed by ongoing need for RRT, i.e., RRT dependence) differ depending on use of CRRT vs. IHD. In a very large US linked hospital-discharge/claims database we found that among ICU patients discharge alive after RRT for AKI, fewer CRRT-treated patients had RRT dependence at hospital discharge (26.5% vs. 29.8%, p = 0.04) and at 90 days after discharge (4.9% vs. 7.4% p = 0.006). In adjusted models, RRT dependence at 90 days postdischarge was >30% lower for CRRT than IHD-treated patients. These results from a non-randomized study suggest that among survivors of RRT for AKI, CRRT may result in less RRT dependence 90 days after hospital discharge.

Bradycardia, Renal Failure, Atrioventricular Block, Shock, and Hyperkalemia (BRASH) Syndrome Emergence in a Unique Intersection of COVID-19 and End-Stage Renal Disease: A Case Report.

Bradycardia, renal failure, atrioventricular (AV) block, shock, and hyperkalemia (BRASH) syndrome is a rare clinical entity that poses challenges for healthcare practitioners. It is characterized by bradycardia, renal failure, atrioventricular (AV) obstruction, shock, and hyperkalemia. This case is an interesting instance of BRASH syndrome in the setting of COVID-19 infection and end-stage renal disease (ESRD). Initial laboratory results revealed macrocytic anemia, renal dysfunction, acidosis, and mild hyponatremia, along with hyperkalemia. An electrocardiogram (EKG) and telemonitoring showed dopamine-resistant persistent bradycardia until transvenous temporary pacemaker placement was done, which resolved the bradycardia. Anti-hyperkalemic therapy, avoiding AV nodal-blocking medication, and temporary pacemaker placement were all part of the management. After receiving hemodialysis, the patient gradually recovered. Bradycardia improved and potassium normalized. The intricate interaction between hyperkalemia and AV nodal obstruction that causes BRASH syndrome results in severe bradycardia and shock. To the best of our knowledge, this is the first case of BRASH syndrome in a patient with an active COVID-19 infection in a previously vaccinated patient. Even though case reports make up the majority of the material currently in publication, to fully comprehend the mechanisms underlying this illness, more research is required, as early detection of this syndrome is crucial for better patient outcomes.

Nafamostat Mesylate for the Hypercoagulable State of SARS-CoV-2 With Renal Replacement Therapy: A Case Report.

Being a dialysis patient is one of the risks for severe coronavirus disease 2019 (COVID-19) cases. In addition, there have been many reports of coagulation abnormalities in severe COVID-19 cases; these also make dialysis management more difficult. In this study, we report a case of severe COVID-19 in a hemodialysis patient who had coagulation in the dialysis circuit with unfractionated heparin (UFH), which could be managed without intracircuit obstruction when nafamostat mesylate (NM) was used in combination with unfractionated heparin.

Characteristics and Outcomes of Children With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection Admitted to a Quaternary Hospital: A Single-Center Experience.

Objectives In the setting of the recent global pandemic, children infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus causing the coronavirus disease 2019 (COVID-19) presented to our hospital with a variety of symptoms ranging from mild to severe disease including multiorgan dysfunction. Our objective was to study the clinical profile, risk factors, complications, and outcomes in pediatric patients admitted to our center with SARS-CoV-2 infection. Methods This retrospective observational study was conducted at a large quaternary center in Riyadh between May 2020 and September 2021. The study population was comprised of children between 0 and ≤14 years with SARS-CoV-2 suspicion or positivity. Results One hundred and fifty-six children were included in the study, the majority of whom were 1-10 years old. One hundred and twenty of them (76.93%) were SARS-CoV-2 positive. Fifty-nine patients (37.18%) were labelled as multisystem inflammatory syndrome in children (MIS-C) based on clinical and lab criteria, of whom 35 (22.44%) tested SARS-CoV-2 positive. Hematological disease was found to be the most common comorbidity, followed by neurological and chronic lung diseases. The most common symptoms encountered were fever, cough, vomiting, fatigue, and diarrhea. Eighty patients (51%) required pediatric intensive care unit (PICU) admission (length of stay: 5-12 days), among whom 32 (40%) required ventilation, 26 (32.5%) needed hemodynamic support, and three patients (3.75%) underwent continuous renal replacement therapy (CRRT). The overall mortality rate was 4.5% (seven patients) among the studied population. The most frequent lab abnormalities were found to be elevated serum ferritin, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and lactate dehydrogenase (LDH) levels. Ninety-one percent received antibiotics, and prophylactic anticoagulant was used in 32%. In the MIS-C subset, 80.5% received steroids, 71.43% intravenous immunoglobulin (IVIG), and 5.17% (three patients) tocilizumab. Conclusion The SARS-CoV-2 infection presented with a range of severity among our cohort of children; however, most of the patients responded well to appropriate supportive treatment. A slight male preponderance was noted. The most common symptoms encountered were fever, cough, vomiting, fatigue, and diarrhea. Inflammatory markers such as ESR, CRP, serum ferritin, and LDH levels were found to be elevated in nearly all patients. Raised serum lactate and serum creatinine and lymphopenia were of significant note in patients with MIS-C. Higher mortality rates were observed in patients with MIS-C and those requiring respiratory support. In addition to these two factors, the presence of comorbidities and the need for CRRT were associated with prolonged PICU length of stay.

T-cell Acute Lymphoblastic Leukemia in Crisis: Hyperleukocytosis, Tumor Lysis Syndrome, and Innovative Approaches.

T-cell acute lymphoblastic leukemia (T-ALL) is a rare hematologic malignancy with a unique set of clinical challenges when it occurs in adults. This case report presents the complex management of a 32-year-old male with T-ALL who developed symptomatic hyperleukocytosis and tumor lysis syndrome. Upon presentation, the patient exhibited a constellation of critical clinical and laboratory findings, including leukocytosis, anemia, thrombocytopenia, hyperkalemia, high-anion gap metabolic acidosis, and acute kidney injury. Despite an initial diagnosis of an allergic reaction, the subsequent course of the disease necessitated rapid medical intervention and consultation with multiple specialties, including hematology-oncology and nephrology. The challenges encountered in managing this patient's condition, particularly in an intensive care unit setting, underscored the need for a tailored and multidisciplinary approach. Treatment modalities included leukapheresis, continuous renal replacement therapy, aggressive fluid resuscitation, and chemotherapy. The case highlights the intricate decision-making processes and adaptability required when addressing T-ALL with hyperleukocytosis and tumor lysis syndrome, particularly in cases where conventional chemotherapy is contraindicated. This report underscores the importance of ongoing research and the need for standardized treatment protocols for such complex clinical scenarios.

Predictors of short-term survival in cardiac valvular surgery patients with intra-aortic balloon pump implantation.

BACKGROUND: Intro-aortic balloon pump (IABP) is widely used in cardiac surgery patients nowadays. This study aimed to analyze the predictor of short-term survival in cardiac valvular surgery patients with intra-aortic balloon pump implantation. METHODS: This was a retrospective study and a total of 102 cardiac valvular surgery patients who received intra-aortic balloon pump implantation were consecutively included. We retrospectively collected the baseline characteristics and short-term outcomes. Baseline characteristics were compared between survivors with non-survivors, and logistic regression was performed to identify predictors for short-term mortality. RESULTS: Among all the patients, there were 71 (69.6%) patients successfully weaned from IABP and survived to discharge, the other 31 (30.4%) patients failed to wean from IABP and died within the first 30 days after surgery. When compared with non-survivors, survivors had a higher proportion of males (62% vs 32.3%, p = 0.006), a lower rate of Atrial fibrillation (38% vs 62%, p < 0.03). After IABP implantation, vasoactive drug use was significantly lower in survivors compared with non-survivors, and survivors showed significant improvements in cardiac function and urine volume. Univariate and multivariate logistic regression analysis indicated that atrial fibrillation and combined use of continuous renal replacement therapy (CRRT) were significant independent predictors for short-term mortality. CONCLUSION: Timely implantation of IABP can improve patients' cardiac and renal function and reduce the dosage of vasoactive drugs. Atrial fibrillation and combined use of CRRT are independent predictors for short-term mortality in patients who underwent cardiac valvular surgery with IABP implantation.

Propofol-Related Infusion Syndrome in a Child With Refractory Status Epilepticus: Successful Resuscitation With Veno-Arterial Extracorporeal Membrane Oxygenation, Continuous Renal Replacement Therapy, and Therapeutic Plasma Exchange.

Propofol is used for sedation, anxiolysis, anesthesia induction, and as an anticonvulsant. In cases of refractory status epilepticus (RSE), propofol is more efficient than barbiturates. We present a case of a 3-year-old female with RSE who developed propofol-related infusion syndrome (PRIS) despite low dosage after failed attempts with multiple anti-epileptic drips and bolus therapies. Careful consideration must be made before initiating propofol administration for RSE. We discuss our PRIS treatment approach with extracorporeal membrane oxygenation, therapeutic plasma exchange, and continuous renal replacement therapy leading to our patient recovering to baseline and being discharged home from the hospital.

Comparison of diluted vs concentrated regional citrate anticoagulation in continuous renal replacement therapy: A quasi-experimental study.

BACKGROUND: The incidence of coagulation of continuous renal replacement therapy circuits remains high. To the best of our knowledge, no scholar has published a protocol to avoid management errors when different types of citrates coexist in the same Intensive Care Unit. AIM: To assess the safety and efficacy of the unification of two protocols with different concentrations of citrate solution. STUDY DESING: A prospective, quasi-experimental study was carried out in the intensive care unit of a tertiary referral hospital (in Barcelona, Spain), over 3 years. Consecutive adult patients requiring continuous renal replacement therapy with citrate were included. The sample was divided into two groups, a control group (concentrated citrate) and an intervention group (diluted citrate). The decision to initiate anticoagulation with diluted (18 mmol/L) or concentrated (136 mmol/L) citrate was made based on the machine available and the decision of the doctor responsible for the patient. It was not possible to randomize the sample. Both protocols were matched with a starting citrate dose of 3.5 mmol/L, and a dialysis solution was used. Post-filter replacement was not used, and the citrate solution was the only fluid administered pre-filter. RESULTS: The analysis included 59 circuits in the concentrated citrate group and 40 circuits in the diluted citrate group. An increased need for electrolyte replacement was observed in the diluted group (p < .001). The concentrated citrate group had a longer filter life (p < .05), and there was a slight trend toward alkalosis. CONCLUSION: The diluted citrate group had a higher incidence of electrolyte replacement. The concentrated citrate group had longer circuit lifespan and a trend toward metabolic alkalosis, although this was not statistically significant. If these conclusions are considered, the protocol can be unified. RELEVANCE TO CLINICAL PRACTICE: The present work aims to provide information on the differences in the use of regional anticoagulation with diluted or concentrated citrate. The objective is to pay special attention to aspects that can lead to complications. The unified protocol proposed in this paper could be extrapolated to any machine on the market that uses either of these two types of citrate concentration.

Acetamiprid and pyridaben poisoning: A case report.

Background: The agricultural industry has experienced beneficial outcomes by implementing contemporary synthetic pesticides, specifically, the mixture of acetamiprid and pyridaben. However, concerns regarding public health have arisen due to the increased number of suicides caused by insecticide poisoning. Nevertheless, limited reports of human exposure to these pesticides have reported various adverse clinical effects. In this study, we present the case of an individual who consumed the acetamiprid and pyridaben mixture for suicidal purposes, and subsequently developed central nervous system depression, hyperlactacidemia, and metabolic acid poisoning, which thus required clinical management. Case report: A 74-year-old woman was transported to our hospital after ingesting a combination of 30 mL of acetamiprid 5 % and pyridaben 5 %. The patient displayed nausea and vomiting symptoms, followed by confusion. An arterial blood gas analysis revealed metabolic acidosis and hyperlactacidemia. The patient was carefully monitored for vital signs and treated with gastric lavage, purgation, and proton pump inhibitors to reduce gastric acid, blood volume, and electrolyte resuscitation. In addition, the patient received 24 h of hemoperfusion (HP) and continuous renal replacement therapy (CRRT). As a result of these interventions, the patient had a speedy recovery and was discharged 10 days later. Conclusion: This case report provided the details of a rare instance of acute poisoning in humans resulting from exposure to newer synthetic pesticides, specifically acetamiprid and pyridaben. The report described the clinical manifestations and effective supportive therapy management. Future clinicians may find the results of this report valuable for identifying clinical symptoms and treating acute poisoning caused by newer synthetic pesticides.

Interaction of ceftazidime and clindamycin with extracorporeal life support.

BACKGROUND: Ceftazidime and clindamycin are commonly prescribed to critically ill patients who require extracorporeal life support such as ECMO and CRRT. The effect of ECMO and CRRT on the disposition of ceftazidime and clindamycin is currently unknown. METHODS: Ceftazidime and clindamycin extraction were studied with ex vivo ECMO and CRRT circuits primed with human blood. The percent recovery of these drugs over time was calculated to determine the degree of interaction between these drugs and circuit components. RESULTS: Neither ceftazidime nor clindamycin exhibited measurable interactions with the ECMO circuit. In contrast, CRRT cleared 100% of ceftazidime from the experimental circuit within the first 2 h. Clearance of clindamycin from the CRRT circuit was slower, with about 20% removed after 6 h. CONCLUSION: Clindamycin and ceftazidime dosing adjustments are likely required in patients who are supported with CRRT, and future studies to quantify these adjustments should consider the pathophysiology of the patient in combination with the clearance due to CRRT. Dosing adjustments to account for adsorption to ECMO circuit components are likely unnecessary and should focus instead on the pathophysiology of the patient and changes in volume of distribution. These results will help improve the safety and efficacy of ceftazidime and clindamycin in patients requiring ECMO and CRRT.

Continuous venovenous hemodiafiltration versus standard medical therapy for the prevention of rhabdomyolysis-induced acute kidney injury: a retrospective cohort study.

AIM: To determine whether continuous venovenous hemodiafiltration (CVVHDF) plus standard medical therapy (SMT) vs. SMT alone prevents rhabdomyolysis (RM)-induced acute kidney injury (AKI) and analyze the related health economics. METHODS: This retrospective cohort study involved 9 RM patients without AKI, coronary heart disease, or chronic kidney disease treated with CVVHDF plus SMT (CVVHDF + SMT group). Nine matched RM patients without AKI treated with SMT only served as controls (SMT group). Baseline characteristics, biochemical indexes, renal survival data, and health economic data were compared between groups. In the CVVHDF + SMT group, biochemical data were compared at different time points. RESULTS: At 2 and 7 days after admission, serum biochemical indices (e.g., myoglobin, creatine kinase, creatinine, and blood urea nitrogen) did not differ between the groups. Total (P = 0.011) and daily hospitalization costs (P = 0.002) were higher in the CVVHDF + SMT group than in the SMT group. After 53 months of follow-up, no patient developed increased serum creatinine, except for 1 CVVHDF + SMT-group patient who died of acute myocardial infarction. In the CVVHDF + SMT group, myoglobin levels significantly differed before and after the first CVVHDF treatment (P = 0.008), and serum myoglobin, serum creatinine, and blood urea nitrogen decreased significantly at different time points after CVVHDF. CONCLUSIONS: Although CVVHDF facilitated myoglobin elimination, its addition to SMT did not improve biochemical indices like serum myoglobin, serum creatine kinase, creatinine, blood urea nitrogen, and lactate dehydrogenase or the long-term renal prognosis. Despite similar hospitalization durations, both total and daily hospitalization costs were higher in the CVVHDF + SMT group.
