Background: Cardiac tumors are rare neoplasms with a wide spectrum of clinical presentations, ranging from asymptomatic cases to fatal outcomes. According to the 2021 thoracic tumor classification of the World Health Organization (WHO), papillary fibroelastoma (PFE) is the most common primary cardiac tumor. This study aimed to aggregate and examine data regarding the prevalence, clinical characteristics, and histological results of cardiac tumors. Methods: This multicenter retrospective study was conducted across seven tertiary care institutions and included 274 patients diagnosed with histopathologically confirmed cardiac tumors between January 2013 and December 2024. Results: This study included 274 patients, with an average age of 52.6 ± 16.6 years. Of the study participants, 120 (43.8%) were male and 154 (56.2%) were female. The most prevalent clinical manifestations were dyspnea (43.7%), thoracic pain (22.5%), and cardiac palpitations (21.1%). Echocardiography was the principal diagnostic method, revealing an average tumor size of 3 cm. The most commonly observed mass was cardiac myxoma (CM) in 192 patients (70.1%). The second most frequently detected mass was PFE (28 cases, 10.2%). The third most common cardiac mass was a metastatic tumor (6.9%). Surgical resection was performed in all patients, with infection being the most prevalent consequence, followed by effusion. Conclusions: Cardiac tumors, albeit uncommon, provide considerable diagnostic and treatment difficulties. Our research is founded on an extensive case series that has been histopathologically validated and sourced from various national tertiary centers. This comprehensive dataset offers epidemiological and clinical insights regarding heart tumors in Turkey. Another key finding of our study is that, even though the 5th edition of the 2021 WHO Classification of Thoracic Tumors lists PFE as the most common primary cardiac tumor, myxoma is actually the most common primary cardiac tumor in our study and in many other studies. This finding demonstrates a significant discrepancy between the current international classification and real-world data and suggests that tumor distribution may be related to regional and demographic differences.

Background/Objectives: Pica, the compulsive ingestion of non-nutritive substances, has long been observed in patients with iron deficiency anemia (IDA). This behavior is particularly noted in adults, including pregnant women, and poses both diagnostic and management challenges. We conducted a review of studies from the past decade to evaluate the epidemiology and nature of pica in adult IDA patients and the outcome of various treatment strategies on anemia and pica behaviors. Methods: We searched PubMed, Scopus, and Cochrane Library for peer-reviewed articles (including observational studies, clinical trials, and reviews) published in English between 2015 and 2025. Inclusion criteria targeted studies of adult populations with IDA that reported on pica prevalence, characteristics, or treatment outcomes. We also reviewed clinical guidelines and meta-analyses on IDA treatment in adults for recommended management approaches. Results: Pica was found to be a prevalent symptom among individuals with IDA, but was readily treatable with appropriate iron deficiency treatment. Among treatment options, both oral and parenteral iron supplementation were found to be effective in resolving iron deficiency and pica. Choice of treatment depends on tolerance to oral iron, speed of resolution required, and comorbid conditions. Conclusions: Pica is closely intertwined with IDA; our review highlighted the prevalence of pica among individuals with IDA, which serves as both a clinical clue to underlying anemia and a potential source of complications. Crucially, the treatment of IDA is also effective for pica. We recommend oral iron therapy on alternate-day dosing as first-line therapy to minimize side effects, alongside dietary optimization. If IDA and pica are resistant to oral iron supplementation or oral iron cannot be tolerated, parenteral iron therapy can be considered. Full article

Objectives: Anisakidosis is an emerging, cosmopolitan, and underdiagnosed parasitic disease caused by the accidental ingestion of third-stage anisakid larvae when consuming raw or improperly prepared seafood. Within hours to days of consuming infected raw seafood, patients may develop acute gastrointestinal symptoms including pain, nausea, vomiting, diarrhea and/or constipation, as live anisakid larvae attach to the gastric, or more rarely, the intestinal mucosa. Cases have been reported in which the nematodes succeed at migrating from the stomach upwards to the esophagus and then the oral cavity. Therefore, the purpose of the present literature review is to collect, analyze, summarize and present the relevant epidemiological, clinical, diagnostic, parasitological, therapeutic, and prognostic data concerning anisakidosis localized inside the oral cavity. Methods: An electronic search of the PubMed, Scopus, and Ovid databases was performed with them being accessed for the last time on 29 March 2025. Results: The present literature review identified 13 individual case reports of oral mucosa anisakidosis, which were published in the period 1971–2022. Conclusions: Our review aims to summarize the relevant epidemiological, clinical, diagnostic, parasitological, therapeutic, and prognostic data regarding the oral localization of anisakidosis, a helminthic infection caused by the accidental ingestion of live anisakid larvae and which manifests mainly with gastrointestinal symptoms. Its localization in the oral mucosa appears to be exceptionally rare and, in most cases, occurs with a characteristic clinical picture, defined by the onset of acute mouth or throat pain immediately after the consumption of raw seafood and by the observation of one or more larvae, either lying on or penetrating the oral mucosa. Despite its rarity, dental health professionals and other clinicians should be aware of this disease and the possibility of its intraoral localization, since environmental factors on the one hand, and the adoption of foreign dietary habits on the other, will likely make anisakidosis a much more common disease worldwide in the near future.

Background and Clinical Significance: Angioleiomyoma (ALM) is a benign tumor that generally presents as a single lesion and, according to the updated WHO classification, includes the following three histological subtypes: solid (or capillary), cavernous, and venous. Typically, ALMs are described as well-defined nodules in the lower extremities but are unusually located in the acral locations and toes. We summarize two cases of ALM and perform a systematic review to provide foot surgeons with the most up-to-date and useful information on the epidemiological aspects, anatomical distribution, and specific histological subtypes of ALM in the foot. Materials and Methods: A systematic review was carried out according to the criteria of a PICO framework, and a systematic search and data processing were carried out according to the PRISMA guidelines. We analyzed patient demographics, clinical characteristics, diagnostic workup, treatment, and clinical outcomes. Each one of the included articles was independently assessed for methodological quality and risk of bias by an independent evaluator. The risk of bias of the included studies was assessed based on their characteristics. Results: This systematic review included 14 case series with 172 reported cases of ALM. One hundred and seventy-two (18.57%) were cases of ALM located on foot, excluding the ankle region. The female-to-male ratio was 1.48. The most common location was the hindfoot (41.5%), followed by the forefoot (20.2%) and the midfoot (8.9%). In 29.4% of cases, the location of the lesions could not be determined. The most frequent location of the lesions was subcutaneous (69%), followed by subaponeurotic (16.5%) and skin (14.5%) locations. The most frequent histological presentation was the solid histologic subtype (65%), followed by the venous subtype (21%) and the cavernous subtype (14%), respectively. Of the total reported cases of ALM located in foot, 63.1% presented as solid painful lesions. Calcified presentations occurred in 7% of cases, with more than half of the cases located in the hindfoot. Surgical excision was the treatment of choice in the two herein reported cases of solid ALM located in the hindfoot, one of them with a calcified presentation. No recurrence was observed in either case after two and five years of follow-up, respectively. All cases reviewed after surgical excision showed a low recurrence rate with a favorable prognosis regardless of the histological subtype and a very rare tendency toward malignancy. Conclusions: ALMs of the foot present as well-defined, painful nodules in the subcutaneous tissue of middle-aged women. Solid histological subtypes are the most prevalent. Histopathological analysis is usually essential for confirmation. Treatment consists primarily of direct excision, with remarkably low recurrence rates. Full article

Background/Objectives: This retrospective multicenter study, conducted within the ORCHESTRA Project, investigated SARS-CoV-2 reinfections among 5777 healthcare workers (HCWs) from four University Hospitals (Modena, Verona, Padova and Trieste) in northern Italy, aiming to assess the risk of reinfection and its determinants, comparing the clinical characteristics of reinfections with those of first infections, and examining the impact of preventive measures and vaccination strategies. Methods: HCWs completed an online questionnaire between June and August 2022. The survey collected demographic, occupational, and clinical data, including information on first infections and reinfections. Statistical analyses were performed using SPSS 28.0, through bivariate and multivariate approaches. Results: Response rates were 41.8% for Modena, 39.5% for Verona, 17.9% for Padova, and 17.4% for Trieste. Among the respondents, 4.8% (n = 276) experienced 2 infections and 0.5% (n = 27) reported 3 infections, out of a total of 330 reinfection cases. Additionally, 43.0% (n = 2787) reported only one infection, while 51.5% were never infected. Reinfection rates increased across five study phases (based on the epidemiological context), likely due to the emergence of new SARS-CoV-2 variants. A booster vaccine dose significantly reduced reinfection risk. Higher reinfection risk was found among HCWs aged ≤30 years, those with chronic respiratory diseases, and those working in COVID-19 wards, particularly nurses and allied health professionals. Reinfections were associated with a lower frequency of symptoms both during the period of swab positivity and after a negative swab, as well as with a shorter duration of swab positivity. No significant differences in symptom duration were found between first infections and reinfections. Conclusions: Despite its limitations, the online questionnaire proved a useful tool. Natural infection and vaccination reduced both reinfection risk and symptom severity. Prior infections should be considered in planning vaccination schedules and prioritizing HCWs. Full article

Background/Objective: Candidemia is a serious complication following intensive chemotherapy and is associated with high mortality in pediatric patients. This study aimed to identify the factors associated with 28-day mortality in pediatric patients with candidemia. Methods: We retrospectively analyzed 63 pediatric patients diagnosed with acute leukemia and candidemia following intensive chemotherapy. Clinical characteristics, laboratory findings, and epidemiological data were collected. Antifungal susceptibility data were available for 60 patients. Kaplan–Meier survival analysis was used to estimate the 28-day mortality rate, and Cox regression was performed to identify prognostic factors. Results: The 28-day mortality rate among the 63 patients (57.1% male, median age 9.74 years) was 36.5%. Candida tropicalis was the predominant species (96.8%). Antifungal susceptibility rates were 100% for amphotericin B and caspofungin and 22.2% for fluconazole. The factors independently associated with reduced 28-day mortality were an absolute lymphocyte count (ALC) ≥ 0.2 G/L at the time of candidemia diagnosis (5.3% vs. 50% mortality; hazard ratio [HR] = 0.08; 95% confidence interval [CI], 0.01–0.61), the use of antifungal prophylaxis (AFP) (26.3% vs. 52%; HR 0.31; 95% CI, 0.13–0.74), and granulocyte transfusion (GTX) combined with granulocyte colony-stimulating factor (G-CSF) (20% vs. 47.4%; HR = 0.31; 95% CI, 0.11–0.85). Conclusions: Our findings suggest that an ALC ≥ 0.2 G/L, AFP, and the administration of a GTX combined with G-CSF may be considered favorable prognostic factors. Full article

Background: Androgen deprivation therapy (ADT) is a primary treatment for prostate cancer (PCa) that effectively reduces androgen levels to suppress tumor progression. However, growing evidence suggests potential cognitive side effects, raising concerns about the long-term neurological consequences of this treatment. Objective: This scoping review aims to synthesize the existing evidence linking ADT to cognitive changes in men with PCa, identifying the key cognitive domains affected and outlining gaps in the existing literature. Methods: A systematic literature search was conducted according to the PRISMA-ScR guidelines in CINAHL, PubMed, Scopus, and Web of Science. Studies investigating cognitive function in ADT-treated PCa patients were included, covering randomized controlled trials (RCTs) and cohort, case–control, and cross-sectional studies. The extracted data included the study design, evaluated cognitive characteristics, measurement tools, and overall findings. Results: A total of 22 studies met the inclusion and exclusion criteria. Cognitive assessments varied across studies. While some studies reported cognitive impairments in ADT-treated patients—particularly in working, verbal, and visual memory and executive function—others found no significant effects. The variability in prostate cancer staging, epidemiological study designs, and treatment regimens; the exclusion of comorbid conditions; and the differences in assessment tools, sample sizes, and study durations hinder definitive conclusions about the cognitive effects of ADT. Conclusions: This scoping review highlights the heterogeneous and often contradictory evidence regarding ADT-associated cognitive dysfunction. While certain cognitive domains may be affected, methodological inconsistencies limit robust conclusions. Standardized cognitive assessments and longer longitudinal studies are required to clarify ADT’s role in cognitive decline. As the PCa survival rate increases with extended ADT use, integrating routine cognitive monitoring into clinical practice should be considered for PCa patients. Full article

Background/Objectives: In late 2019, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) caused a pandemic called the ‘coronavirus disease 2019’ (COVID-19). After the acute SARS-CoV-2 infection, many individuals (up to 33%) complained of unexplained symptoms involving multiple organ systems and were diagnosed as having Long COVID-19 (LC-19). Currently, LC-19 is inadequately defined, requiring the formation of consistent diagnostic parameters to provide a foundation for ongoing and future studies of epidemiology, risk factors, clinical characteristics, and therapy. LC-19 represents a significant burden on multiple levels. The reduced ability of workers to return to work or compromised work efficiency has led to consequences at national, economic, and societal levels by increasing dependence on community services. On a personal scale, the isolation and helplessness caused by the disease and its subsequent impact on the patient’s mental health and quality of life are incalculable. Methods: In this paper, we used Walker and Avants’ eight-step approach to perform a concept analysis of the term “Long COVID-19” and define its impact across these parameters. Results: Using this methodology, we provide an improved definition of LC-19 by connecting the clinical symptomology with previously under-addressed factors, such as mental, psychological, economic, and social effects. This definition of LC-19 features can help improve diagnostic procedures and help plan relevant healthcare services. Conclusions: LC-19 represents a complex and pressing public health challenge with diverse symptomology, an unpredictable timeline, and complex pathophysiology. This concept analysis serves as a tool for improving LC-19 definition, but it remains a dynamic disease with evolving diagnostic and therapeutic approaches, requiring deeper investigation and understanding of its long-term effects.

Background: Urinary tract trauma encompasses injuries to the kidneys, ureters, urinary bladder, and urethra and can result from both external and iatrogenic causes. We aimed to evaluate the epidemiology, clinical characteristics, and in-hospital outcomes of urinary tract trauma in Germany. Methods: We analyzed data from the GeRmAn Nationwide inpatient Data (GRAND) registry, provided by the Research Data Center of the Federal Bureau of Statistics, from 2005 to 2023. We included patients admitted to the hospital with kidney, ureteral, urinary bladder, or urethral trauma. We assessed baseline characteristics, perioperative outcomes, surgical interventions, in-hospital all-cause mortality, and trends. Results: We identified 239,657 patients with urinary tract trauma: 109,376 with kidney, 34,330 with ureteral, 57,886 with bladder, and 38,065 with urethral trauma. While the incidence of kidney trauma declined, the incidence of ureteral, bladder, and urethral trauma steadily increased over time. Kidney trauma was the most common trauma, affecting younger males (median age of 47 years), and was associated with in-hospital all-cause mortality of 2.4% and transfusion rates of 15%. Ureteral stenting was necessary in 9.3% and nephrectomy in 2.6% of all patients with kidney trauma. Moreover, ureteral, bladder, and urethral trauma predominantly affected older, multimorbid patients, leading to higher rates of transfusion (22–25%), intensive care unit admission (12–15%), and mortality (3.2–6.4%). Ureteral anastomosis was necessary in 14% of all ureteral injuries. Bladder repair was required in 53% of all patients with bladder injury, while 1% of these patients required cystectomy. Accordingly, urethral reconstruction was performed in 7.2% of all patients with urethral trauma. Conclusions: These findings highlight the evolving landscape of urinary tract trauma and underscore the need for tailored management strategies and preventive measures. Full article

Background/Objectives: Erysipelas is an acute bacterial skin infection, particularly affecting the lower limbs, with a tendency to recur. Despite its clinical importance, data on demographic and epidemiological risk factors, as well as factors influencing hospitalization, remain limited. This study aimed to analyze the epidemiological and clinical characteristics of patients hospitalized with primary and recurrent erysipelas, focusing on risk factors contributing to disease onset, recurrence, and prolonged hospitalization. Methods: A retrospective single-center analysis was conducted on 239 patients hospitalized for erysipelas at the Department of Dermatology, Pediatric Dermatology, and Oncology at the Medical University of Lodz. Data collected included demographics, lesion location, laboratory markers, comorbidities, and hospitalization outcomes. Statistical analyses were performed to assess associations between risk factors, disease recurrence, and hospitalization duration. Results: The majority of erysipelas cases (85.4%) involved the lower limbs, with a higher prevalence in men. Upper extremities were mostly affected in women, especially those who had undergone breast cancer surgery. Recurrent erysipelas accounted for 75.7% of cases. Most patients (89.1%) had at least one comorbidity, with hypertension, diabetes type 2 (DM2), and obesity being the most common. Higher white blood cell (WBC) count, obesity, atrial fibrillation (AF), and the need for enoxaparin administration were independently associated with prolonged hospitalization. Dyslipidemia was significantly associated with erysipelas recurrence (p < 0.05). Conclusions: Both primary and recurrent erysipelas are associated with specific risk factors. Recurrent erysipelas may be linked to components of metabolic syndrome, particularly obesity and dyslipidemia, which emerged as a significant risk factor in this study. Hospitalization length may be prolonged by inflammation markers (WBC and CRP) and comorbidities such as AF, obesity, or the need for enoxaparin in patients with elevated thrombosis risk. Further multicenter studies with larger cohorts are needed to assess the impact of demographics, biomarkers, metabolic disorders, and treatment strategies on erysipelas recurrence and outcomes. Awareness of these risk factors is essential for effective prevention, management, and recurrence reduction. Full article

Background/Objectives: The rising demand for total joint arthroplasty (TJA) and increasing incidence of prosthetic joint infections (PJIs) significantly burden patients and healthcare systems. This retrospective study describes the epidemiology, clinical characteristics and outcomes of PJIs in Iceland from 2003 to 2020. Methods: PJI cases were identified through synovial fluid cultures and ICD codes, with classification per EBJIS criteria. Unlikely cases were excluded. Results: Among 293 cases with a mean age of 70 years, 60% (176/293) were males and 58% (171/293) involved the knee. Over half of infections occurred within two years post TJA, with an incidence rate of 0.94%, increasing significantly over time (p = 0.012). Males had significantly higher incidence rates than females (incidence rate ratio 0.42; p < 0.001). The most common pathogens were coagulase-negative staphylococci (30%, 88/293), and 9% (27/293) of cases were culture-negative. DAIR was the first-line treatment in about 50% (147/293) of cases but it failed in nearly half, contributing to an overall treatment failure rate of 38% (98/259). PJI-related mortality was 2% (6/293). Conclusions: The results indicate an increased incidence, with the highest risk within two years of TJA. Males are at greater risk, while females more commonly undergo TJA. DAIR success rates were lower than reported elsewhere but improved significantly over time. Better methods to prevent PJIs are needed. Full article

Hepatitis E virus (HEV) poses a significant public health concern, particularly among immunocompromised populations. This study aimed to investigate HEV seroprevalence, clinical characteristics, and associated risk factors in people living with HIV (PLWH) in Shanghai, China. A retrospective analysis was conducted on serum IgG and IgM antibodies specific to HEV in 670 PLWH and 464 HIV-negative health-check attendees. The overall anti-HEV seropositivity rate among PLWH was 30.15% (202/670, 95% CI 26.68–33.62), with an IgG positivity rate of 30.00% (201/670, 95% CI 26.53–33.47). IgM positivity was observed in 1.19% (8/670, 95% CI 0.59–2.39) of PLWH, and dual IgM/IgG positivity was observed in 1.04% (7/670, 95% CI 0.50–2.16) of PLWH. The seropositivity rate of anti-HEV IgG in the HIV-negative health-check attendees was 17.67% (82/464, 95% confidence interval: 14.20–21.14), with no IgM positivity, which was significantly lower than that in PLWH (χ² = 22.84, p < 0.001). Univariate and multivariate analyses identified advanced World Health Organization (WHO) HIV stage (III/IV) as an independent risk factor for HEV co-infection (p < 0.05). Notably, no significant associations were observed with age, gender, CD4 count, or liver function parameters. These findings underscore the importance of implementing HEV screening protocols and developing targeted preventive strategies for PLWH. Full article

Background: Osteogenesis imperfecta (OI) is a rare genetic connective tissue disorder characterized by bone fragility, most often caused by pathogenic variants in type I collagen genes. In this context, we aimed to describe the clinical and epidemiological characteristics of patients with OI who were hospitalized for coronavirus disease (COVID)-19 in Brazil between 2020 and 2024. Methods: We conducted a retrospective descriptive analysis using data from the Brazilian Unified Health System (SUS, which stands for the Portuguese Sistema Único de Saúde) through the Open-Data-SUS platform. Patients with a confirmed diagnosis of OI and hospitalization due to COVID-19 were included. Descriptive statistical analysis was performed to evaluate demographic, clinical, and outcome-related variables. We included all hospitalized COVID-19 cases with a confirmed diagnosis of OI between 2020 and 2024. Results: Thirteen hospitalized patients with OI and COVID-19 were identified. Most were adults (9; 69.2%), male (7; 53.8%), self-identified as White (9; 69.2%), and all were residents of urban areas (13; 100.0%). The most frequent symptoms were fever (10; 76.9%), cough (9; 69.2%), oxygen desaturation (9; 69.2%), dyspnea (8; 61.5%), and respiratory distress (7; 53.8%). Two patients had heart disease, one had chronic lung disease, and one was obese. As for vaccination status, five patients (38.5%) had been vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Four patients (30.8%) required admission to an intensive care unit (ICU), and six (46.2%) required noninvasive ventilatory support. Among those admitted to the ICU, only two required invasive mechanical ventilation. The clinical outcome was death in two cases (15.4%). Both patients were male, White, and had not been vaccinated against SARS-CoV-2. One was 47 years old, was not admitted to the ICU, but required noninvasive ventilation. Despite the underlying condition most patients had favorable outcomes, consistent with an international report. Conclusions: This is the first report to describe the clinical and epidemiological profile of patients with OI hospitalized for COVID-19 in Brazil, providing initial insights into how a rare bone disorder intersects with an acute respiratory infection. The generally favorable outcomes observed—despite the underlying skeletal fragility—suggest that individuals with OI are not necessarily at disproportionate risk of severe COVID-19, particularly when appropriately monitored. The occurrence of deaths only among unvaccinated patients underscores the critical role of SARS-CoV-2 vaccination in this population. Although pharmacological treatment data were unavailable, the potential protective effects of bisphosphonates and vitamin D merit further exploration. These findings support the need for early preventive strategies, systematic vaccination efforts, and dedicated clinical protocols for rare disease populations during infectious disease outbreaks.

Background/Objectives: Colorectal cancer (CRC) is one of the major epidemiological oncological confronts with established risk factors, including male sex. Still, CRC is reported among the leading malignancies in the female population. The necessity for possible, easily accessible prognostic factors is required to improve patient outcomes. This study aimed to assess sex-related differences in nine-month four-stage CRC results of palliative systemic therapy. Methods: A total of 67 patients (39 males) with a median age of 70 (64–76) years were referred for first-line palliative chemotherapy due to end-stage colorectal cancer diagnosis. The CRC advancement was evaluated by computed tomography (CT) before and 9 months after chemotherapy. The demographical and clinical characteristics were evaluated for nine-month therapy outcomes, including mortality risk and CT scan results. Results: The nine-month mortality risk in female and male groups was indifferent, reaching 21% (6 patients) and 21% (8 patients), respectively (p = 0.935). Among survivors, therapy response was observed in 6 (21%) female and 20 (51%) male patients (p = 0.056). In multivariable analysis, the male sex (OR: 3.91, 95% CI: 1.09–14.05, p = 0.037) and RDW (OR: 0.61, 95% CI: 0.42–0.88, p = 0.008) were found to be significant for disease response to systemic therapy based on CT scan results. The ROC curve for predictive role yields a sensitivity of 71.1%, specificity of 57.8%, and an area under the curve (AUC) of 0.726. Conclusions: Our analysis points out the possible favorable role of the male sex on nine-month systemic therapy response in palliative CRC. The RDW-CV can be regarded as a possible indicator of chemotherapy response in colorectal cancer. The mortality risk within 9 months of systemic therapy is comparable between males and females.

Alzheimer’s disease (AD) is one of the main causes of dementia, with an exponential increment in its incidence as years go by. However, since pathophysiological mechanisms are complex and multifactorial, therapeutic strategies remain inconclusive and only provide symptomatic relief to patients. In order to solve this problem, new strategies have been investigated over recent years for AD treatment. This field has been reborn due to epidemiological and preclinical findings that demonstrate the fact that omega-3 polyunsaturated fatty acids (ω-3 PUFAs) can be promising therapeutic agents because of their anti-inflammatory, antioxidant, and neurogenic-promoting activities, thus allowing us to classify these molecules as neuroprotectors. Similarly, ω-3 PUFAs perform important actions in the formation of characteristic AD lesions, amyloid-β plaques (Aβ) and neurofibrillary tangles, reducing the development of these structures. Altogether, the aforementioned actions hinder cognitive decline and possibly reduce AD development. In addition, ω-3 PUFAs modulate the inflammatory response by inhibiting the production of pro-inflammatory molecules and promoting the synthesis of specialised pro-resolving mediators. Consequently, the present review assesses the mechanisms by which ω-3 PUFAs can act as therapeutic molecules and the effectiveness of their use in patients. Clinical evidence so far has shown promising results on ω-3 PUFA effects, both in animal and epidemiological studies, but remains contradictory in clinical trials. More research on these molecules and their neuroprotective effects in AD is needed, as well as the establishment of future guidelines to obtain more reproducible results on this matter. Full article
