In the present research,we simultaneously addressed the condition of osteomyelitis and osteoporosis by developing a gelatin based chemically cross linked cryogel system embedded with CaCO3 microspheres and ciprofloxacin hydrochloride was incorporated in both the microspheres and the 3D matrix of cryogel. The fabricated cryogel was characterized for the swelling ratio, swelling kinetics, porosity, pore volume, compression strength and in vitro rate of degradation which were found to be dependent on the concentration of gelatin, duration of freezing and number of freeze-thaw cycles. The sustained release of drug was obtained up to 21days after the initial burst, and the concentration was maintained above the MIC for the entire duration of the study. The in vitro antibacterial study in Staphylococcus aureus and Escherichia coli exhibited 33mm, 30mm, 28mm, 27mm and 43mm, 37mm, 37mm, and 36mm zone of inhibition respectively at day 1, 3, 5 and 7. The cell viability, number of cells in the growth phase and alkaline phosphatase levels were found to be significantly higher in rat osteoblasts cultured in cryogel as compared to 2D surface. All these results demonstrate the propitious potential of this microsphere incorporated, ciprofloxacin-loaded, industrially scalable cryogel system for therapeutic intervention in osteoporosis and associated osteomyelitis.

Objective: The objective of this study is to assess the predictive utility of perioperative P-wave parameters in patients with paroxysmal atrial fibrillation (PAF) undergoing catheter ablation, and to develop a predictive model using these parameters.
Methods: A total of 213 patients with PAF undergoing catheter ablation were retrospectively analyzed. P-wave parameters were measured within 3 days preoperatively and on the day postoperatively to determine their predictive significance for postoperative PAF recurrence.
Sperm DNA fragmentation index: limited effectiveness on predicting embryo quality in assisted reproduction technology treatments.

Purpose: Prior sperm DNA fragmentation index (DFI) thresholds for diagnosing male infertility and predicting assisted reproduction technology (ART) outcomes fluctuated between 15 and 30%, with no agreed standard. This study aimed to evaluate the impact of the sperm DFI on early embryonic development during ART treatments and establish appropriate DFI cut-off values.
Methods: Retrospectively analyzed 913 couple's ART cycles from 2021 to 2022, encompassing 1,476 IVF and 295 ICSI cycles, following strict criteria.
Repression of PFKFB3 sensitizes ovarian cancer to PARP inhibitors by impairing homologous recombination repair.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

HIV self-sampling and -testing (HIVSS/ST) reduces testing barriers and potentially reaches populations who may not test otherwise. In the Netherlands, at-home HIV tests became commercially available around 2016, but data on user experiences are limited. This study aimed to explore characteristics of users and their experiences with HIVSS/ST.

Background: The PalliPed project is a nationwide, observational, cross-sectional study designed with the aim of providing a constantly updated national database for the census and monitoring of specialized pediatric palliative care (PPC) activities in Italy. This paper presents the results of the first monitoring phase of the PalliPed project, which was developed through the PalliPed 2022-2023 study, to update current knowledge on the provision of specialized PPC services in Italy.
Methods: Italian specialized PPC centers/facilities were invited to participate and asked to complete a self-reporting, ad-hoc, online survey regarding their clinical activity in 2022-2023, in the revision of the data initially collected in the first PalliPed study of 2021.
