Acute heart failure (AHF) episodes are marked by high rates of morbidity and mortality during the episode and minimal advancements in its care. Multiple biomarker monitoring is now a crucial supplementary technique in the therapy of AHF. A scientific literature search was conducted by assessing and evaluating the most pertinent research that has been published, including original papers and review papers with the use of PubMed, Medline, and Cochrane databases. Established biomarkers like natriuretic peptides (BNP, NT-proBNP) and cardiac troponins play crucial roles in diagnostic and prognostic evaluation. Emerging biomarkers such as microRNAs, osteopontin, galectin-3, ST2, and GDF-15 show promise in enhancing risk stratification and predicting adverse outcomes in HF. However, while these biomarkers offer valuable insights, their clinical utility requires further validation and integration into practice. Continued research into novel biomarkers holds promise for early HF detection and risk assessment, potentially mitigating the global burden of HF. Understanding the nuances of biomarker utilization is crucial for their effective incorporation into clinical practice, ultimately improving HF management and patient care.

Pulmonary embolism (PE) is the third most common type of cardiovascular disease and carries a high mortality rate of 30% if left untreated. Although it is commonly known that individuals who suffer heart failure (HF) are more likely to experience a pulmonary embolism, little is known concerning the prognostic relationship between acute PE and HF. This study aims to evaluate the prognostic usefulness of heart failure and pro-BNP in pulmonary embolism cases. A scientific literature search, including PubMed, Medline, and Cochrane reviews, was used to assess and evaluate the most pertinent research that has been published. The findings showed that increased N-terminal brain natriuretic peptide (NT-proBNP) levels could potentially identify pulmonary embolism patients with worse immediate prognoses and were highly predictive of all-cause death. Important prognostic information can be obtained from NT-proBNP and Heart-type Fatty Acid Binding Proteins (H-FABP) when examining individuals with PE. The heart, distal tubular cells of the renal system, and skeletal muscle are where H-FABP is primarily found, with myocardial cells having the highest concentration. Recent studies have indicated that these biomarkers may also help assess the severity of PE and its long-term risk.

Review
BACKGROUND
Magnolia officinalis, a traditional herbal medicine widely used in clinical practice, exerts antibacterial, anti-tumor, anti-inflammatory, antioxidant, and anti-aging activities. Neolignans are the main active ingredients of M. officinalis and exert a wide range of pharmacological effects, including anti-Alzheimer's disease (AD) activity.
OBJECTIVE
To summarize the published data on the therapeutic effect and mechanism of neolignans on AD in vivo and in vitro.
METHODS
PubMed, Web of Science, Google Scholar, and Scopus were systematically reviewed (up to March 1, 2024) for pre-clinical studies.
RESULTS
M. officinalis-derived neolignans (honokiol, magnolol, 4-O-methylhonokiol, and obovatol) alleviated behavioral abnormalities, including learning and cognitive impairments, in AD animal models. Mechanistically, neolignans inhibited Aβ generation or aggregation, neuroinflammation, and acetylcholinesterase activity; promoted microglial phagocytosis and anti-oxidative stress; alleviated mitochondrial dysfunction and energy metabolism, as well as anti-cholinergic deficiency; and regulated intestinal flora. Furthermore, neolignans may achieve neuroprotection by regulating different molecular pathways, including the NF-κB, ERK, AMPK/mTOR/ULK1, and cAMP/PKA/CREB pathways.
CONCLUSIONS
Neolignans exert anti-AD effects through multiple mechanisms and pathways. However, the exact targets, pharmacokinetics, safety, and clinical efficacy in patients with AD need further investigation in multi-center clinical case-control studies.

Review
INTRODUCTION
Tick-borne pathogens (TBPs) constitute an emerging threat to public and animal health especially in the African continent, where land-use change, and wildlife loss are creating new opportunities for disease transmission. A review of TBPs with a focus on ticks determined the epidemiology of Rhipicephalus ticks in heartwater and the affinity of each Rickettsia species for different tick genera. We conducted a systematic review and meta-analysis to collect, map and estimate the molecular prevalence of Anaplasmataceae, Rickettsiaceae and Coxiellaceae in African wildlife.
MATERIALS AND METHODS
Relevant scientific articles were retrieved from five databases: PubMed, ScienceDirect, Scopus, Ovid and OAIster. Publications were selected according to pre-determined exclusion criteria and evaluated for risk of bias using the appraisal tool for cross-sectional studies (AXIS). We conducted an initial descriptive analysis followed by a meta-analysis to estimate the molecular prevalence of each pathogen. Subgroup analysis and meta-regression models were employed to unravel associations with disease determinants. Finally, the quality of evidence of every estimate was finally assessed.
RESULTS
Out of 577 retrieved papers, a total of 41 papers were included in the qualitative analysis and 27 in the meta-analysis. We retrieved 21 Anaplasmataceae species, six Rickettsiaceae species and Coxiella burnetii. Meta-analysis was performed for a total of 11 target pathogens. Anaplasma marginale, Ehrlichia ruminantium and Anaplasma centrale were the most prevalent in African bovids (13.9 %, CI: 0-52.4 %; 20.9 %, CI: 4.1-46.2 %; 13.9 %, CI: 0-68.7 %, respectively). Estimated TBPs prevalences were further stratified per animal order, family, species and sampling country.
DISCUSSION
We discussed the presence of a sylvatic cycle for A. marginale and E. ruminantium in wild African bovids, the need to investigate A. phagocytophilum in African rodents and non-human primates as well as E. canis in the tissues of wild carnivores, and a lack of data and characterization of Rickettsia species and C. burnetii.
CONCLUSION
Given the lack of epidemiological data on wildlife diseases, the current work can serve as a starting point for future epidemiological and/or experimental studies.

BACKGROUND
Semaglutide, a glucagon-like peptide-1 receptor agonist, is reported to have cardiac benefits, but its effects on preventing atrial fibrillation (AF) remain inconclusive. This study aimed to investigate whether semaglutide can prevent AF occurrence in patients with type 2 diabetes mellitus (T2DM), obesity, or overweight.
METHODS
We searched MEDLINE, EMBASE, the Cochrane CENTRAL database, and clinicaltrials.gov from inception to December 29, 2023. Randomized controlled trials of semaglutide in patients with T2DM, obesity, or overweight were included. The primary outcome was AF occurrence. Relative risks (RRs) with 95 % confidence intervals (CIs) were calculated for the overall population and subgroups.
RESULTS
Twenty-one trials comprising 25957 patients were included. In the overall pooled analysis, semaglutide decreased AF occurrence compared to control drugs (RR 0.70, 95 % CI 0.52-0.95). This result was consistent in trials using other antihyperglycemic medications as controls (RR 0.43, 95 % CI 0.21-0.89), but not in placebo-controlled trials (RR 0.77, 95 % CI 0.56-1.07). The outcome was favorable for patients with T2DM (RR 0.71, 95 % CI 0.52-0.97), but not for patients with overweight or obesity (RR 0.56, 95 % CI 0.18-1.73). Results varied by type of semaglutide, with oral semaglutide showing an RR of 0.49 (95 % CI 0.25-0.97) and subcutaneous semaglutide showing an RR of 0.77 (95 % CI 0.55-1.07).
CONCLUSION
Semaglutide was associated with a reduced risk of AF occurrence in the overall analysis. Favorable outcomes were observed in subsets using other antihyperglycemic medications as controls, in patients with T2DM, and with oral semaglutide.

Review
Pain is essential for survival, but individual responses to painful stimuli vary, representing a complex interplay between sensory, cognitive, and affective factors. Individual differences in personality traits and in pain perception covary but it is unclear which traits play the most significant role in understanding the pain experience and whether this depends on pain modality. A systematic search identified 1534 records (CINAHL, MEDLINE, PsycInfo, PubMed and Web of Science), of which 22 were retained and included in a systematic review. Only studies from the pressure pain domain (n=6) could be compared in a formal meta-analysis to evaluate the relationship between Big Five traits and experimental pain. Pressure pain tolerance correlated positively with Extraversion and negatively with Neuroticism with a trivial effect size (<0.1). While these findings suggest personality might be only weakly related to pain in healthy individuals, we emphasize the need to consider standardization, biases, and adequate sample sizes in future research, as well as additional factors that might affect experimental pain sensitivity.

Review
BACKGROUND
Systemic sclerosis (SSc) is a heterogenous, multi-system autoimmune disease that causes progressive fibrosis of the skin and internal organs, resulting in high morbidity and mortality. Intravenous Immunoglobulin (IVIG) is a therapeutic option for SSc; however, reports of its efficacy have been variable, and its use across multiple organ manifestations of SSc has not been comprehensively reviewed.
AIM
The aim of this study was to systematically assess the existing literature on the role of IVIG use across a range of SSc manifestations.
METHODS
Medline, Embase, Cochrane, Web of Science and Scopus were searched from 01/01/2003-15/04/2024 using terms related to SSc and IVIG. Included studies were English-language full texts, where ≥5 adults with SSc received IVIG, and where a reportable outcome was documented.
RESULTS
Of 418 potentially relevant records, 12 were included in this review, comprising 266 patients across one randomised control trial, two pilot studies, one open label study, seven retrospective studies and one case control study. Eighteen outcomes were documented across five different organ systems: cutaneous, respiratory, musculoskeletal, gastrointestinal, and other (clinical improvement and corticosteroid sparing benefit). Results showed a favourable effect of IVIG in reducing the extent of skin thickening, muscle and joint pain, gastrointestinal symptoms, steroid dosing and improving patient/physician reported quality of life. Whilst IVIG may appear to be less beneficial for respiratory disease, the stabilisation in pulmonary function tests and radiological features may be considered a positive outcome in itself. Limitations included a lack of high-quality studies, and the use of concomitant therapies in many studies, rendering the efficacy of IVIG alone difficult to ascertain.
CONCLUSION
IVIG showed benefit in treating some manifestations of SSc, however there was a lack of convincing evidence for the efficacy in others. The lack of high-quality data highlights the need for further well-designed clinical trials to confirm these findings and inform guidelines for IVIG use.

INTRODUCTION
While available systemic treatments have modest long term efficacy in advanced angiosarcoma, immunotherapy represents an interesting new therapeutic opportunity. To establish its benefit, it is required to conduct a clinical trial assessing its efficacy and toxicity compared to standard treatments.
MATERIAL AND METHODS
This is a literature review from PubMed search.
RESULTS
Several systemic treatments (chemotherapy and TKI) are currently used in advanced angiosarcoma with ORR ranging from 12.5 to 68 % and PFS from 2 to 7 months. However, few randomized trials, mainly phase II, has been conducted to compare these treatments. While most centers propose doxorubicin containing regimens or paclitaxel in 1st or 2nd line, a high heterogeneity of regimens administered in this setting is observed even across sarcoma specialized centers with no consensual standard treatment. Encouraging signals of immunotherapy activity have been reported in angiosarcoma from several retrospective and phase II studies assessing anti-PD1 either alone or in combination with anti CTLA4 or TKI. Although cutaneous and head and neck location seems to benefit more from immunotherapy, response may be observed in any angiosarcoma subtype. In sarcoma in general and AS in particular, no biomarker has been clearly established to predict the efficacy of immunotherapy: high tumor mutational burden and presence of tertiary lymphoid structures are under assessment.
DISCUSSION
Even essential, developing a randomized clinical trial in AS struggles with the heterogeneity of the disease, the lack of consensual standard regimen, the uncertainty on optimal immunotherapy administration and the absence of established predictive biomarkers.
CONCLUSION
International collaboration is essential to run randomized trial in advanced AS and asses the efficacy of immune therapy in this rare and heterogeneous disease.

Review
BACKGROUND
Pure germinoma typically originates from the midline and is usually found in the pineal and suprasellar regions in 76-90 % of cases. When it is in both regions, it is considered bifocal (10 % at diagnosis). If pure germinoma is located outside of the midline, it is considered ectopic, with a global incidence of about 0.7 %. The study aims to describe the clinical and surgical approach to patients with atypical intracranial ectopic germinoma (IEG) and bifocal germinoma (BG) through a literature review with the goal to delineate the correct diagnostic and therapeutic pathway, to reduce the diagnostic delay and improve the prognosis of these patients.
METHODS
A systematic review of the literature in most common electronic database (PubMed, Ovid MEDLINE and Ovid EMBASE) on IEG and BG, in according with the "PRISMA statement" criteria, from January 1990 to September 2022 was done. In addition, two rare cases of IEG and BG were reported.
RESULTS
This systematic review included 16 papers (20 patients) with a final diagnosis of IEG and 30 papers (121 patients) with a final diagnosis of BG. IEGs seems to involve primary basal ganglia (40 %) and corpus callosum (40 %). For IEGs, biopsy (70 %, 14 cases out of 20) was the most common surgical approach: open approach (35 %), stereotactic minimally invasive approach (30 %) or endoscopic trans-sphenoidal approach (5 %). Partial resection was performed in 10 % of cases, whereas a total resection was performed in 20 % of cases. Also for BGs, biopsy was the most common surgical approach in 80 % of patients, whereas surgical resection (partial or total) was performed in 5.3 % of patients.
CONCLUSION
IEG and BG are rare type of primary intracranial germ cell tumor, whose unusual location often can cause delays in diagnosis, which can have a significant impact on the patient's prognosis and requiring a multidisciplinary and timely approach.

To review the effects of the ketogenic diet on epilepsy in children and adolescents. A literature search was conducted in PubMed with no publication date or language restrictions based on the Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines. Keywords used included , , , , and . After excluding articles that did not meet the inclusion criteria, such as missing variables of study, adult population, and nonrandomized clinical trials, a total of 12 studies were included in the final review. Data on study design, duration, sample size, population, and type of intervention were collected using a standard template. The ketogenic diet and its modified versions were noted to have beneficial effects in reduction of seizure frequency and severity, with manageable adverse effects such as gastrointestinal disturbances, dehydration, dyslipidemia, hyperuricemia, infection, and metabolic acidosis. Depending on patient compliance and comorbidities, all variations of the ketogenic diet were found to be helpful for seizure treatment, whether as an additive or an alternative treatment option, for children and adolescents with epilepsy. .
