As the leading cause of neonatal morbidity and mortality, preterm birth is recognized as a major public health concern around the world. The purpose of this review is to analyze the connection between infections and premature birth. Spontaneous preterm birth is commonly associated with intrauterine infection/inflammation. The overproduction of prostaglandins caused by the inflammation associated with an infection could lead to uterine contractions, contributing to preterm delivery. Many pathogens, particularly Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Gardnerella vaginalis, Ureaplasma urealyticum, Mycoplasma hominis, Actinomyces, Candida spp., and Streptococcus spp. have been related with premature delivery, chorioamnionitis, and sepsis of the neonate. Further research regarding the prevention of preterm delivery is required in order to develop effective preventive methods with the aim of reducing neonatal morbidity.

Hyperlipidemia is characterized by abnormally increased plasma of any or all lipids and /or lipoproteins and is a confirmed risk factor for the formation of atherosclerosis. Inflammation plays a crucial role in the formation and progression of atherosclerosis and consequently on cardiovascular diseases. Nowadays, the effective role of the immune system and subsequently of systemic inflammation is well established. Multiple levels of evidence from experimental models and histopathologic assessment of tissues to systemic biomarkers and epidemiologic or clinical associations have revealed that inflammation is one of the basic mechanisms in the destabilization of the atherogenetic plaque which leads to clinical events. Several inflammatory markers are affiliated with lipids level and the process of atherosclerosis. The most known of them are interleukin 6 and interleukin 1β, C-reactive protein, tumor necrosis factor-alpha, pentraxin3, serum amyloid A, sCD40, adhesion molecules, monocyte chemoattractant protein-1, sEndoglin, PAPP-A, chemokine 16, insulin like growth factor, lipoprotein-associated phospholipase A2 and galectin 3 but their role in atherogenesis is not well established for all of them. As atheromatosis is one of the main causes of death all over the world, in upcoming studies it will be useful to specify the exact role of these markers in this process in order to have a better prognosis, diagnosis and understanding of this disorder. The aim in this review is to study the literature on the novel inflammation markers of hyperlipidemia according to their clinical implications.

Gestational diabetes mellitus (GDM) occurs in approximately 9–25% of pregnancies and, if left undiagnosed or inadequately controlled, can lead to adverse outcomes for both the mother and the fetus, short and long term. GDM is characterized by glucose intolerance with onset or first recognition during pregnancy and is a multifactorial condition with a pathophysiology that remains incompletely understood. It is strongly associated with a chronic low-grade inflammatory state that contributes to insulin resistance, a hallmark of GDM pathogenesis. Among the fundamental pro-inflammatory cytokines implicated in this process, TNF-α and IL-6 play central roles. TNF-α is a cytokine primarily secreted by activated macrophages, as well as by adipocytes in the context of obesity. Many studies have shown that its levels are elevated in pregnant women with GDM compared to normoglycemic pregnant individuals. IL-6 is another pro-inflammatory cytokine secreted by immune cells, adipose tissue, and the placenta. It is found in higher concentrations in the maternal circulation during pregnancies complicated by GDM. Both TNF-α and IL-6 act synergistically to perpetuate a pro-inflammatory intrauterine environment. Their combined effects exacerbate insulin resistance and may impair pancreatic β-cell compensation during pregnancy, facilitating the onset of GDM in genetically or metabolically susceptible individuals. Recent research has identified various maternal serum biomarkers, such as TNF-α and IL-6, that may hold promise for the early detection of GDM. The aim of our study is to evaluate whether TNF-α and IL-6 can be used as diagnostic tools for the early diagnosis of GDM, allowing for timely intervention and reducing the risk of associated maternal and fetal complications.

Preeclampsia (PE) occurs in approximately 2–8% of all pregnancies worldwide and represents one of the primary causes of maternal and fetal morbidity and mortality. Angiogenic growth factors such as placental growth factor (PlGF) and vascular endothelial growth factor (VEGF), along with their tyrosine kinase receptor (Flt-1), play a central role in placental and fetal development. Impaired placentation results in the excessive release of the antiangiogenic soluble fms-like tyrosine kinase-1 (sFlt-1) which is pivotal in the pathogenesis of PE. By binding to and neutralizing angiogenic factors, sFlt-1 disrupts normal angiogenic signaling, creating an imbalance that is often detectable before clinical symptoms of PE appear. Recent studies have highlighted the prognostic potential of the sFlt-1/PlGf ratio as an early indicator of PE risk, since this ratio has demonstrated value in both confirming and excluding PE in the high-risk population. Its incorporation into routine medical care has the potential to reduce unnecessary hospital admissions, intensive management, and premature deliveries, ultimately lowering healthcare costs. The objective of this review is to highlight the clinical utility of the sFlt-1/PlGf ratio in the prediction, diagnosis, and management of preeclampsia and to emphasize the cost-effectiveness of implementing sFlt-1/PlGF ratio measurement in the care of women at risk of developing PE.

Objective: Osteonectin plays a central role in various processes during the development of pancreatic adenocarcinoma. This prospective pilot study was performed to determine the feasibility of serum osteonectin as a screening tool for pancreatic cancer. Methods: Blood samples were collected from 15 consecutive patients with newly diagnosed pancreatic cancer and 30 matched healthy controls. Serum osteonectin was measured using an osteonectin enzyme-linked immunosorbent assay kit. The primary outcomes were the diagnostic performance of serum osteonectin and the threshold value for differentiation of patients from controls. Results: The median/quartile range of serum osteonectin in patients and controls were 306.8/288.5 ng/mL and 67.5/39.8 ng/mL, respectively. Osteonectin concentrations significantly differed among the study groups. A plasma osteonectin concentration of >100.18 ng/mL as selected by the receiver operating characteristic curves demonstrated an estimated area under the curve of 86% for prediction of pancreatic cancer. Tumour size was a significant predictor of serum osteonectin. A statistically significant difference in serum osteonectin between T1/T2 and T3/T4 tumours was found. Post-hoc comparisons revealed statistically significant differences in the serum osteonectin among the control, T1/T2, and T3/T4 groups. Conclusion: Osteonectin may be used as a screening tool for pancreatic cancer, although this must be validated in prospective studies.

Background/Objectives: Infertility constitutes a significant challenge for couples around the world. Ovarian dysfunction, a major cause of infertility, can manifest with anovulatory cycles, elevated follicle-stimulating hormone levels, and diminished ovarian reserve markers such as anti-Müllerian hormone (AMH) levels or the Antral Follicle Count (AFC). Blood-derived therapies including platelet-rich plasma (PRP) have been used in fertility treatments in women with low ovarian reserve or premature ovarian insufficiency. This prospective clinical cohort study aims to assess the effects of intraovarian PRP therapy on ovarian function in women diagnosed with anovulatory cycles. Methods: The preliminary findings of this prospective cohort study are based on the first 32 patients enrolled. In this study, patients over 40 years old with anovulatory infertility were included. Venous blood samples were collected from each participant for the preparation of autologous platelet-rich plasma (PRP). Each participant received two courses of intraovarian PRP injections using a transvaginal ultrasound-guided approach. Serum levels of reproductive hormones before and after PRP intervention were measured. Results: This study’s results demonstrate a significant improvement in ovarian physiology following transvaginal ultrasound-guided PRP infusion. A 75% increase in Antral Follicle Count (AFC) was observed, which was statistically significant. Furthermore, statistically significant reductions in follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin levels were observed. Serum Vitamin D 1–25 levels were substantially increased after the injection. Conclusions: These findings highlight the beneficial impact of intraovarian PRP injection in optimizing ovarian function and other metabolic parameters. However, the published literature on this subject is limited and further clinical studies should be conducted to confirm the role of intraovarian PRP in fertility treatments.
