Introduction: Primary intraosseous mucoepidermoid carcinoma is a rare malignancy originating from minor or ectopic salivary gland tissue within the jawbones, presenting diagnostic challenges, especially in young patients. This article is aimed at oral and maxillofacial radiologists, surgeons, oncologists, and dental practitioners who encounter such cases, highlighting the importance of early recognition for effective treatment planning.
Case Presentation: Two cases of primary intraosseous mucoepidermoid carcinoma in the maxilla are presented. The first involves a 27-year-old female with pain and swelling in the left upper jaw. Cone-beam computed tomography showed a multicystic hypodense lesion with bicortical expansion and palatal perforation. The second case features a 15-year-old with similar radiographic findings but with additional lymph node involvement, indicating a more aggressive disease. The first case was localized and painful, while the second was painless, with the lesion extending into the maxillary sinus. Diagnoses were confirmed via fine needle aspiration cytology and histopathology, followed by surgical resection.
Conclusion: These cases highlight the need for clinicians to consider primary intraosseous mucoepidermoid carcinoma as a differential diagnosis for jaw swellings across all ages. Advanced imaging, particularly cone-beam computed tomography, is crucial for precise diagnosis and early intervention, leading to improved patient outcomes.

Diabetes mellitus type 2 is a chronic disease caused by insulin resistance. Whilst first originating in the adipose tissue, this pathophysiological process later affects the muscles and the liver as well. This induces high plasma levels of glucose and fatty acids, leading to the inflammatory-related chronic complications of diabetes, such as diabetic nephropathy and diabetic cardiovascular disease. Specialized pro-resolving mediators are lipid mediators responsible for resolving inflammation and could therefore be beneficial in the management of chronic diabetes complications. The aim of this review is to assess if specialised pro-resolving mediators have the potential to attenuate the chronic complications of diabetes. Specialised pro-resolving mediators, especially lipoxins, can modulate both diabetic nephropathy and diabetic cardiovascular disease. In mice it was demonstrated that, at the glomerular level, lipoxins reduced collagen deposition and expression of pro-inflammatory markers. In human saphenous vein smooth muscle cells instead, lipoxins were able to reduce collagen deposition and vascular smooth muscle cells proliferation and chemotaxis. Aspirin is a medication that could be used to modulate specialised pro-resolving mediator levels, as aspirin triggered-specialised pro-resolving mediators exist. Aspirin triggered-specialised pro-resolving mediators are pro-resolving substances with similar effects, but synthetised in a different way, requiring the partial blockage of the cyclooxygenase 2 enzyme. These results demonstrate how such substances could be useful in the treatment of diabetic patients and why further research is needed to create efficient and economical medications.

Introduction: Severe hyperkalemia is a life-threatening condition that demands a rapid diagnosis and prompt treatment. The following case report highlights the possible complexity in the clinical presentation of this condition and the importance of a thorough assessment of patients that do not provide the classical clinical findings.
Case presentation: A 40-year-old male called the emergency services for low blood pressure and an overall altered state. Upon arrival, the prehospital team found a patient with shock signs that was complaining of feeling unwell and reported profuse diarrhea starting three days prior. Additionally, the patient also had muscle weakness and occasional spastic movements of the limbs and face. During the assessment, the patient went suddenly into cardiac arrest, life support (including the management of hyperkalemia) was immediately started and return of spontaneous circulation was soon obtained. Point-of-care blood testing established the diagnosis of severe hyperkalemia. Definitive in-hospital care consisted mainly of fluid resuscitation, circulatory support, hemodialysis and antimicrobial therapy and the patient was discharged 16 days later with no neurological impairment.
Conclusions: Although atypical, hyperkalemia can be caused by diarrhea in certain circumstances and its clinical manifestations can be misleading. Thus, keeping a broad clinical perspective and early use of blood tests can ensure proper treatment of life-threatening hyperkalemia.

Objective: This paper aimed to synthesize hybrids of fluoroquinolones with tetracycline class representatives and conduct their preliminary characterization.
Methods: A reaction between tetracycline representatives (doxycycline, tetracycline), formaldehyde (acting as a molecular connector) and fluoroquinolone representatives (ciprofloxacin, moxifloxacin, and norfloxacin) was attempted through a classical reflux synthesis with an electrical heating source (heating mantles) and a microwave-assisted reflux synthesis. One synthesis group also used cupric chloride dihydrate as a catalyst. The samples were analyzed using Differential Scanning Calorimetry, Electrospray Ionization Mass Spectrometry, or High-Performance Liquid Chromatography.
Results: The results indicated the formation of a compound different from the parent components in the case of doxycycline-norfloxacin and possibly tetracycline-norfloxacin hybrids.
Conclusions: Both synthesis methods yielded similar results. The influence of the catalyst did not seem to have been significant. The synthesis method is simple and one-step, using non-toxic solvents. Future studies involving molecular docking and microbiology could be employed to further explore the mechanism of action and the microbiological effects of the hybrids.

Objective: A comparative study was performed to evaluate the food impact on the pharmacokinetics of indapamide 1.5 mg prolonged release tablets (SR).
Methods: The data evaluated were collected from 2 randomized, single dose, 2-way crossover bioequivalence studies with administration of indapamide to healthy Caucasian volunteers under fasting and fed conditions, respectively. Forty-four eligible subjects aged 19–39 years were enrolled in both studies: 22 subjects received indapamide under fasting (study 1) and the other 22 under fed (study 2) conditions. Blood samples were collected following the same schedule before and up to 96.0 hours after drug administration. Blood concentration of indapamide were quantified by a validated LC-MS/MS method. A non-compartmental analysis was used to calculate the pharmacokinetic parameters. Mathematical deconvolution was applied to assess indapamide absorption. Statistical significance for differences in key pharmacokinetic parameters was evaluated using an ANOVA test, with a significance threshold of p < 0.05.
Results: In total, 44 subjects were included in analysis. The outcomes demonstrated that ingestion of food independently reduced the mean of tmax by 4.64 h and increased the value of Cmax by 19.7 ng/mL, while the AUC remained unchanged.
Conclusions: Notably, differences in drug absorption rate obtained after co-administration of indapamide with food had no significant influence in safety and efficacy of the drug.

Objective: This study evaluated antipyretic potency of methanol extracts of Cissampelos pareira, Lantana camara and Ocimum gratissimum in Wistar rats.
Methods: The leaves samples were obtained from Embu County, Kenya. Quantitative phytochemical analysis of the extracts was conducted using LC-MS and GC-MS methods. The study was performed in eight sets each with 5 Wistar rats (n = 5): positive control, normal control, negative control as well as experimental. Group I (normal control) rats were injected intraperitoneally with a solution of Dimethyl sulfoxide (DMSO) only. Group II (negative control) constituted rats initiated with fever using turpentine alongside DMSO. Group III, (positive control) rats were induced with pyrexia and then administered with aspirin. Groups IV, V, VI, VII, and VIII composed of turpentine-induced pyretic rats that were intraperitoneally injected with various extracts dosages. The data was analysed using Statistical Package for Social Sciences (v25) software.
Results: The plant extracts possess antipyretic activities that are comparable to the standard therapy, aspirin. Quantitative phytochemistry showed that the extracts contained bioactive principles such as terpenoids, flavonoids, and alkaloids which exert antipyretic activity.
Conclusion: The studied plants are rich in secondary metabolites that have antipyretic efficacies in rats. Hence, this study validates the folkloric use of the tested plants to manage fever among the Mbeere community in Kenya.

The genetic landscape of early and late-onset Alzheimer’s disease: A review

Paula Denisa Saragea

Department of Biology, “Alexandru Ioan Cuza” University of Iasi, Romania

DOI: 10.2478/amma-2024-0030

Alzheimer’s disease(AD) is a multifactorial neurodegenerative disorder characterized by the progressive loss of neurons and synaptic dysfunction, primarily affecting the cortex and hippocampus. The etiology of AD is complex, involving the continuous and intricate interaction between genetic and non-genetic environmental factors. Genetic predisposition plays a significant role, with approximately 60-80% of AD risk attributed to hereditary factors. Familial early-onset AD(EOAD), with autosomal-dominant mutations in APP, PSEN1, and PSEN2, represents about 1-5% of cases and typically manifests before age 65. Rare autosomal-recessive mutations, like A673V(APP gene), are also implicated. Late-onset AD(LOAD), more common, is influenced by a combination of genetic and environmental factors, with the APOE ε4 allele being a major risk factor. Protective factors, such as the APOE ε2 allele and rare mutations like Ala673Thr, can reduce AD risk. The interplay between genetic variants, environmental influences, and pathological processes underpins the disease’s progression. This study highlights the importance of understanding the genetic and non-genetic determinants of AD to advance personalized treatment and early detection strategies. Future research and personalized medicine approaches are essential for mitigating AD risks and improving management outcomes.

Introduction: Outcome and predictors of early- and late-onset septic shock are still controversial. The aim of the study was to compare the relevant predictors of 28-day mortality in early- and late-onset septic shock and other non-septic critical illnesses.
Material and Methods: We conducted a prospective, observational, pilot study. A group of 46 patients with early septic shock and 42 non-septic critically ill patients from the emergency department and 56 patients with late septic shock from the hospital were enrolled. On admission to the ICU, the most important potential predictors of 28-day mortality were assessed.
Results: In terms of predicting 28-day mortality, a higher mNUTRIC score was the only common predictor for all three groups. Multi-drug resistant (MDR) bacterial aetiology was a common predictor in both forms of septic shock. Older age, female gender, increased neutrophil-to-lymphocyte ratio (NLR) and increased need for vasoactive agents were common predictors in late septic shock and non-septic critically ill patients. Increased red blood cell distribution width coefficient of variation (RDW-CV) was predictor in early septic shock and non-septic critically ill patients. Central venous-arterial carbon dioxide difference (Pcv-aCO2) was predictor in patients with early septic shock. Inflammatory index and MDR carrier status were predictors in non-septic critically ill patients.
Conclusions:A higher mNUTRIC score is a predictor of 28-day mortality in early and late septic shock and in critically ill non-septic patients. MDR aetiology was predictive of 28-day all-cause mortality in both types of septic shock, and Pcv-aCO2 was predictive in patients with early septic shock.
