: Atherosclerosis is a chronic pathological condition that has remained clinically silent for decades, and the epidemic has continued to be on the rise due to risk factors, including diet, lifestyle, hyperlipidemia, pathogenic microorganisms, and aging. Using various synthetic drugs in treating atherosclerosis is associated with a high risk of myositis, angioedema, myoglobinuria, and acute renal failure. Various side effects of the available drugs have been reported; attempts are underway to explore natural sources with antiatherosclerotic activity. : Using a diet-induced atherosclerosis rat model, the current study tested the hypothesis of antiatherosclerotic and antihyperlipidemic roles of fruit extracts. : Atherosclerosis in Wistar rats was induced using an atherogenic diet. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (AP), creatine kinase (CK), and lactate dehydrogenase (LDH) were determined using analytical kits. : Quantitative phytochemical analysis of the extracts demonstrated that the plant had flavonoids, saponins, tannins, terpenoids, alkaloids, cardiac glycosides, sterols, phenols, and anthraquinones. Diet-induced atherogenic Wistar rats showed a significant ( < 0.05) increase in total cholesterol, triglyceride, low-density lipoprotein cholesterol, and very low-density lipoprotein cholesterol compared to the healthy control group; however, the atherogenic lipid profile was reversed by the treatment of fruit extracts. The biochemical experiments demonstrate that fruit extracts have an antihyperlipidaemic effect, shown by a decreased coronary risk index and the atherogenic index, and an increased cardioprotective index, compared to disease control. : The current study indicates that fruit extracts may contain bioactive molecules to treat atherosclerosis.

Rhabdomyolysis is a potentially fatal adverse reaction mostly triggered by certain medications. Few real-world studies have shown a clear association between newer-generation anti-seizure medications (ASMs) and rhabdomyolysis. We sought to quantify the risk and evaluate the clinical features and management of rhabdomyolysis associated with newer-generation ASMs. Data were retrieved from the US FDA Adverse Event Reporting System database (FAERS) from 2018 to 2022 on newer-generation ASMs to identify rhabdomyolysis events, and disproportionality analyses were conducted by estimating the reporting odds ratios (RORs) and corresponding 95% confidence intervals (CIs). Furthermore, case reports from 2012 to 31 December 2022 on newer-generation ASMs-induced rhabdomyolysis were retrieved for retrospective analysis. A total of 1,130 rhabdomyolysis reports from the FAERS database were considered. Levetiracetam had the greatest proportion and the highest positive signal values of rhabdomyolysis. The RORs (95% CIs) for newer-generation ASMs were, in descending order, levetiracetam 8.01 (7.26-8.84), lamotrigine 3.78 (3.25-4.40), oxcarbazepine 3.47 (2.53-4.75), pregabalin 2.75 (2.43-3.12), lacosamide 1.85 (1.29-2.65), topiramate 1.64 (1.25-2.15), and gabapentin 1.32 (1.13-1.55). Twenty-six case reports showed evidence of rhabdomyolysis, and levetiracetam (65.4%) was the most frequently reported agent. The median age was 32 years; typical initial symptoms included muscle weakness (34.8%), myalgia (34.8%), backache (17.4%), fatigue (13.0%) and leg pain (8.7%). The median time to onset of rhabdomyolysis was 2 days. All cases had elevated creatine phosphokinase (CPK), and some cases were accompanied by elevated creatinine (57.1%) and myoglobinuria (53.8%). Cessation of ASMs could lead to complete clinical remission. The median time for creatine phosphokinase (CPK) normalization was 8 days. This study identified 7 newer-generation ASMs with significant rhabdomyolysis reporting associations. Prescribers should be more aware of this risk and teach patients to recognize rhabdomyolysis signs/symptoms early.

On February 6, two major earthquakes with magnitudes of 7.8 and 7.7 on the Richter scale hit Turkey and Northern Syria causing more than 50,000 deaths. In the immediate aftermath of the earthquakes, our major tertiary medical referral center received dozens of cases of crush syndrome, presenting with a variety of imaging findings. Crush syndrome is characterized by hypovolemia, hyperkalemia, and myoglobinuria that can lead to rapid death of victims, despite their survival of staying under wreckage for days. The typical triad of crush syndrome consists of the acute tubular necrosis, paralytic ileus, and third-space edema. In this article, we focus primarily on characteristic imaging findings of earthquake-related crush syndrome and divided them into two distinct subsections: myonecrosis, rapid hypovolemia, excessive third-space edema, acute tubular necrosis, and paralytic ileus, which are directly related to crush syndrome, and typical accompanying findings of earthquake-related crush syndrome. Lower extremity compression in earthquake survivors results in the typical third-space edema. In addition to the lower extremities, other skeletal muscle regions are also affected, especially rotator muscles, trapezius, and pectoral muscles. Although it may be relatively easy to better detect myonecrosis with contrast-enhanced CT scans, changing the windowing of the images may be helpful.

Introduction/Aims HyperCKemia is considered a hallmark of neuromuscular diseases. It can be either isolated or associated with cramps, myalgia, weakness, myoglobinuria, or rhabdomyolysis, suggesting a metabolic myopathy. The aim of this work was to investigate possible genetic causes in order to help diagnose patients with recurrent hyperCKemia or clinical suspicion of inherited metabolic myopathy. Methods A cohort of 139 patients (90 adults and 49 children) was analyzed using a custom panel containing 54 genes associated with hyperCKemia. Results A definite genetic diagnosis was obtained in 15.1% of cases, while candidate variants or variants of uncertain significance were found in a further 39.5%. Similar percentages were obtained in patients with infantile or adult onset, with some different causative genes. was the gene most frequently identified, either with single or compound heterozygous variants, while variants were the most common cause for recessive cases. In one patient, mRNA analysis allowed identifying a large deletion missed by DNA sequencing, leading to a certain diagnosis. Conclusion These data confirm the high genetic heterogeneity of hyperCKemia and metabolic myopathies. The reduced diagnostic yield suggests the existence of additional genes associated with this condition but also allows speculation that a significant number of cases presenting with hyperCKemia or muscle symptoms are due to extrinsic, not genetic, factors.

BACKGROUND
Crush syndrome (CS) is a systemic condition resulting from rhabdomyolysis caused by prolonged pressure on muscle tissue. It is estimated that CS will develop in approximately 2-5% of all injuries related to an earthquake, and acute kidney injury (AKI) will develop in approximately 1.5% of all injuries. The present study aimed to present the evaluation of pediatric patients with CS who developed AKI to determine the risk factors that can be determined beforehand for the need for dialysis and to present a new scoring developed for dialysis indication.
METHODS
Pediatric patients with CS and who underwent dialysis for AKI were included in the study. The study was conducted retrospectively and as single-center data. A renal scoring system that determines the indications for dialysis in patients with CS by parameters of eGFR, creatine phosphokinase (CPK), time under rubble, presence of amputation or fasciotomy, and urine volume was included.
RESULTS
The mean age was 11.53 ± 4.50 years, and 58.4% of the group were male. Among the 77 patients, 33 (42.8%) underwent kidney replacement therapy (KRT). Renal score, CPK level, and presence of myoglobinuria were determined to be the best markers for KRT indication in pediatric patients with CS (p < 0.01, p = 0.02, and p < 0.01, respectively).
CONCLUSIONS
We suggest that if a similar disaster occurs in the future, an easy and applicable renal scoring system can contribute to the prognosis by providing appropriate and early treatment for KRT. A higher resolution version of the Graphical abstract is available as Supplementary information.

BACKGROUND
Bloody urine is classified in farm animals as hematuria, hemoglobinuria, and myoglobinuria. In small ruminants, discolored urine is reported due to several etiologies which is sometimes fatal. Of these causes are babesiosis, bacillary hemoglobinuria, copper toxicity, and hypophosphatemia.
AIM
This study was designed to investigate the clinical, etiological, hematobiochemical, ultrasonographic, and pathological findings in rams and bucks with red urine syndrome.
METHODS
Eighteen male animals (nine rams and nine bucks) of 6 months to 3 years were examined. Parallel, 10 healthy controls were used. They were admitted due to red urine, voiding of only urine drops, straining during the act of urination, grunting during urination, ventral abdominal edema, and abdominal distension. The duration of the disease ranged from 2 to 30 days. A history of chronic copper toxicosis was informed in two bucks and a ram. Two blood samples were collected from diseased as well as from controls in EDTA tubes (for complete blood count testing) and in plain tubes (for serum collection).
RESULTS
Hematuria was found in 11 animals (seven bucks and four rams) while hemoglobinuria was detected in seven animals (five bucks and two rams). Sonographic findings in diseased animals included ruptured urinary bladder in 3, ruptured urethra in 5, penile calculi, uroperitoneum in 6, distended urinary bladder in 7, hydronephrosis in 5, echogenic deposits in the bladder in 3, and ventral urine accumulation in four animals. Laboratory evaluation of a Geimsa-stained blood smear confirmed the infection with Babesia in three bucks and a ram. Hemolytic anemia was marked in two bucks and a ram due to chronic copper toxicity. Biochemical abnormalities included hypoalbuminemia, hyperglobulinemia, increased blood urea nitrogen and creatinine concentration, and hyperglycemia. Postmortem examination was carried out on six animals (four rams and two bucks).
CONCLUSION
Discolored urine in rams and bucks in this study resulted from hematuria due to urinary calculi and pelvic abscessation or from hemoglobinuria due to Babesia infection or due to copper toxicity. Hemolytic anemia was the outstanding hematological finding and hypoalbuminemia, hyperglobulinemia, increased blood urea nitrogen (BUN) and creatinine, and hyperglycemia were the characteristic biochemical findings. Sonography of the urinary tract was very helpful in assessing the renal parenchyma, urinary bladder, and abdominal cavity for the verification of urolithiasis, hydronephrosis, intact or ruptured urinary bladder, uroperitoneum, and perforated urethra.

This report describes the case of a 47-year-old woman with myalgias, weakness, and elevated creatine kinase associated with semaglutide therapy prescribed for weight loss. Her symptoms and laboratory markers were consistent with rhabdomyolysis and resolved after discontinuation of semaglutide. Upon rechallenge at a lower dose, symptoms recurred, and urinalysis was consistent with myoglobinuria. Symptoms again rapidly resolved upon discontinuation of the medication. It is imperative for physicians to recognize semaglutide as a possible cause of myalgias and rhabdomyolysis in clinically suspected patients. To the best of our knowledge, this is the first reported case in the literature and may be specific to semaglutide rather than a class effect of glucagon-like peptide 1 (GLP-1) agonists.

BACKGROUND
Malignant hyperthermia (MH) susceptibility is a heritable musculoskeletal disorder that can present as a potentially fatal hypermetabolic response to triggering anesthesia agents. Genomic screening for variants in MH-associated genes RYR1 and CACNA1S provides an opportunity to prevent morbidity and mortality. There are limited outcomes data from disclosing variants in RYR1, the most common MH susceptibility gene, in unselected populations. The authors sought to identify the rate of MH features or fulminant episodes after triggering agent exposure in an unselected population undergoing genomic screening including actionable RYR1 variants.
METHODS
The MyCode Community Health Initiative by Geisinger (USA) is an electronic health record-linked biobank that discloses pathogenic and likely pathogenic variants in clinically actionable genes to patient-participants. Available electronic anesthesia and ambulatory records for participants with actionable RYR1 results returned through December 2020 were evaluated for pertinent findings via double-coded chart reviews and reconciliation. Descriptive statistics for observed phenotypes were calculated.
RESULTS
One hundred fifty-two participants had an actionable RYR1 variant disclosed during the study period. None had previous documented genetic testing for MH susceptibility; one had previous contracture testing diagnosing MH susceptibility. Sixty-eight participants (44.7%) had anesthesia records documenting triggering agent exposure during at least one procedure. None received dantrolene treatment or had documented muscle rigidity, myoglobinuria, hyperkalemia, elevated creatine kinase, severe myalgia, or tea-colored urine. Of 120 possibly MH-related findings (postoperative intensive care unit admissions, hyperthermia, arterial blood gas evaluation, hypercapnia, or tachycardia), 112 (93.3%) were deemed unlikely to be MH events; 8 (6.7%) had insufficient records to determine etiology.
CONCLUSIONS
Results demonstrate a low frequency of classic intraanesthetic hypermetabolic phenotypes in an unselected population with actionable RYR1 variants. Further research on the actionability of screening for MH susceptibility in unselected populations, including economic impact, predictors of MH episodes, and expanded clinical phenotypes, is necessary.

UNLABELLED
Hepatitis A is a mild self-limiting infection of the liver with spontaneous resolution of symptoms in most cases. However, clinicians should be aware of some commonly encountered complications and extrahepatic manifestations associated with hepatitis A for timely diagnosis and treatment. Rhabdomyolysis, an exceedingly rare complication of hepatitis A, is scarcely documented. We present a case of a 64-year-old man with symptoms consistent with rhabdomyolysis and an evanescent rash secondary to acute hepatitis A. He eventually recovered with conservative management. This case emphasizes the importance of recognizing and treating atypical presentations of acute hepatitis A infection.
LEARNING POINTS
The case underscores the importance of recognizing and treating atypical presentations of acute hepatitis A infection. Clinicians should be vigilant for unusual manifestations of common infections, facilitating timely diagnosis and appropriate management. Rhabdomyolysis is identified as an exceedingly rare complication of hepatitis A infection, which is scarcely documented in the literature. This case contributes to the growing understanding of extrahepatic manifestations associated with hepatitis A, emphasizing the importance of considering uncommon complications in the differential diagnosis, especially when typical clinical presentations are observed. The article discusses the treatment approach for rhabdomyolysis secondary to acute hepatitis A, which involves aggressive fluid resuscitation to prevent kidney damage from myoglobinuria, correction of electrolyte imbalances, and metabolic abnormalities. Additionally, vaccination against hepatitis A and advocating for sanitation measures are highlighted as important preventive strategies.
