Hydrogels are water-rich polymeric networks mimicking the body’s extracellular matrix, making them highly biocompatible and ideal for precision medicine. Their “tunable” and “smart” properties enable the precise adjustment of mechanical, chemical, and physical characteristics, allowing responses to specific stimuli such as pH or temperature. These versatile materials offer significant advantages over traditional drug delivery by facilitating targeted, localized, and on-demand therapies. Applications range from diagnostics and wound healing to tissue engineering and, notably, cancer therapy, where they deliver anti-cancer agents directly to tumors, minimizing systemic toxicity. Hydrogels’ design involves careful material selection and crosslinking techniques, which dictate properties like swelling, degradation, and porosity—all crucial for their effectiveness. The development of self-healing, tough, and bio-functional hydrogels represents a significant step forward, promising advanced biomaterials that can actively sense, react to, and engage in complex biological processes for a tailored therapeutic approach. Beyond their mechanical resilience and adaptability, these hydrogels open avenues for next-generation therapies, such as dynamic wound dressings that adapt to healing stages, injectable scaffolds that remodel with growing tissue, or smart drug delivery systems that respond to real-time biochemical cues.

Polycystic ovary syndrome (PCOS), a common and multifactorial endocrine disorder in reproductive-aged women, is strongly associated with insulin resistance (IR) and type 2 diabetes mellitus (T2DM), and also affects up to one in four women with type 1 diabetes mellitus (T1DM). The current study explored the potential of Plantago ovata (P. ovata) seed ethanol extract (POEE) to modulate oxidative stress (OS), inflammatory responses, metabolic profiles, and hormonal levels in rat Streptozotocin (STZ)-induced DM and Letrozole (LET)-induced PCOS. Phytochemical analysis measured total phenolic content (TPC) and total flavonoid content (TFC) using HPLC-DAD-ESI MS for compound identification. POEE’s antioxidant activity was evaluated in vitro through DPPH, H₂O₂, FRAP, and NO scavenging assays. Rats received POEE, metformin, or Trolox (TX) for 10 days. PCOS confirmation was achieved via ultrasound and histopathology. Serum levels of OS markers (TOS, TAC, OSI, MDA, AOPP, 8-OHdG, NO, 3-NT, AGEs, and SH), inflammatory markers (NF-κB, IL-1β, IL-18, Gasdermin D, and IL-10), metabolic parameters (fasting blood glucose, lipid profile, and liver enzymes), and hormone levels (LH, FSH, estrogen, testosterone, and insulin) were assessed. Additionally, the Triglyceride–Glucose index (TyG) and HOMA-IR were calculated. POEE had a medium content of polyphenols and a good in vitro antioxidant effect. In vivo, POEE administration in diabetic rats led to a reduction in OS markers and an increase in antioxidant levels, alongside decreases in inflammatory cytokines, blood glucose levels, and transaminase activity and improvements in lipid profile. In the PCOS model, POEE treatment effectively reduced total OS and lowered levels of LH, FSH, and testosterone, while elevating estrogen concentrations and reducing insulin resistance. These therapeutic effects were dose-dependent, with higher doses producing more pronounced outcomes, comparable to those observed with metformin and TX treatment.

Supracondylar humeral fractures are the most common type of elbow fractures in children. The treatment methods vary depending on the type of fracture (Gartland classification), which can be conservative or surgical. There is no clear consensus or guidelines to dictate the treatment of complicated supracondylar humeral fractures (Gartland types II and III). Gartland type II and III fractures are most frequently treated with closed reduction and percutaneous Kirchner-wire pinning or open reduction with K-wire pinning, depending on the degree of displacement and the orthopedic surgeon’s preference. Most studies recommend avoiding open reduction because of prolonged hospitalization and higher rates of complications. Orthopedic surgeons have different opinions regarding the Kirschner pin placement technique. Studies suggest that only lateral pinning is safe and effective, but medial and lateral pinning is proven to give more stability; there is always a risk of iatrogenic ulnar nerve damage during surgery. Modern treatment of supracondylar humeral fracture in children should focus on minimally invasive techniques and avoid open reduction, when possible, to ensure the best outcome for the patients. This scoping review’s purpose is to gather the available information on the topic in one place and to underline the lack of clear protocols.

Polycystic ovary syndrome (PCOS) and diabetes mellitus (DM) are prevalent endocrine disorders with overlapping pathophysiological mechanisms. Type 2 diabetes mellitus (T2DM) is commonly associated with PCOS, with both conditions strongly linked to insulin resistance (IR), while recent studies have also reported an increased prevalence of PCOS among women with type 1 diabetes mellitus (T1DM). This study evaluated the potential of Lythrum salicaria L. ethanol extract (LSEE) to mitigate oxidative stress (OS), inflammation, and metabolic and hormonal imbalances in separate experimental models of Streptozotocin (STZ)-induced DM and Letrozole (LET)-induced PCOS. LSEE underwent phytochemical analysis to quantify total phenolic and flavonoid content and HPLC-MS for polyphenols identification. In vitro, antioxidant capacity was investigated through FRAP, DPPH, NO, and H₂O₂ scavenging assays. Subsequently, in vivo, studies utilized STZ-induced DM and LET-induced PCOS rat models, with 10-day treatments of LSEE, metformin, or trolox (TX) administered by gavage. Dysregulation of hormonal profiles, ultrasound, and histological examinations confirmed PCOS development. At the end of the treatment period, serum samples were collected to assess OS markers (TOS, OSI, MDA, AOPP, 8-OHdG, NO, 3-NT, AGEs, TAR, SH) in both models. Inflammatory markers were also measured (IL-1β, NF-κB, IL-18, and Gasdermin D in DM and IL-1β, NF-κB, IL-18, and IL-10 in PCOS). Additionally, metabolic markers (glucose, lipids, TG-glucose index, liver enzymes) were assessed in DM rats, and hormones (LH, FSH, estrogen, testosterone, insulin, HOMA-IR) were determined in PCOS rats. LSEE demonstrated a high polyphenolic content and notable in vitro antioxidant activity. In vivo, it effectively reduced OS by lowering oxidant levels and enhancing antioxidant defenses, reduced inflammatory markers and blood glucose levels, and improved lipid profiles along with the TyG index and liver injury markers in diabetic rats. In PCOS rats, LSEE lowered the total oxidants, increased antioxidants, reduced LH, FSH, testosterone, and insulin, and increased estrogen levels. The effects exhibited a dose-dependent pattern, with higher doses producing more pronounced benefits comparable to those observed with metformin and TX. In conclusion, LSEE may be a promising complementary treatment for DM and PCOS.

Background and objectives: Pelvic inflammatory disease (PID), primarily associated with sexually transmitted infections (STIs), represents a diagnostic challenge in virgin pediatric patients due to the often vague, non-specific symptomatology, which can mimic other conditions. Management prioritizes targeted antimicrobial therapy, with surgical intervention reserved for complications like tubo-ovarian abscess (TOA). The present systematic review aimed to critically evaluate the available evidence from case reports of PID in virgin pediatric and adolescent patients. Methods: The search strategy was in accordance with PRISMA guidelines. Case reports published up to March 2025 were searched through PubMed, Embase, Scopus, and Google Scholar databases. We included English-language case reports on non-sexually active pediatric and adolescent patients with available full text, excluding commentaries, reviews, and editorials. The Critical Appraisal Checklist for Case Reports was used for the quality assessment of case reports. Through descriptive analysis, PID symptoms, diagnostic, and management modalities were reviewed. The quality of the included case reports was assessed using the JBI Critical Appraisal Checklist. This review was not registered and did not receive external funding. Results: Among the 56 case reports searched, 20 reports were selected and analyzed based on eight criteria. The most frequently reported symptoms were lower abdominal pain (95.8%), fever (63.6%), and gastrointestinal symptoms (50%). Common comorbidities included urinary tract infections (22.7%), congenital anomalies (18.1%), and appendicitis history (18.1%). Escherichia coli and Streptococcus species were the predominant pathogens identified. All patients received antibiotic therapy, while 90.9% underwent surgical intervention. Favorable outcomes were achieved in 72.7% of cases, though 27.2% experienced complications or recurrences. Conclusions: Although commonly linked to sexual activity, PID should be considered in sexually inactive pediatric patients presenting with abdominal pain and adnexal masses. Early diagnosis, appropriate imaging, and timely treatment are crucial to improve outcomes and reduce complications. The evidence in this review is limited by its reliance on case reports, which may introduce bias and restrict generalizability.
