Article Multisensory Stimulation by Mothers: Impact on Neonatal Pain and Maternal Anxiety During Heel Blood Collection: A Randomized Controlled Trial(Springernature, 2025) Akkaya-Gul, Aysenur; Ozyazicioglu, Nurcan; Celikboya-Kabadayi, EzgiOBJECTIVE: This study aimed to evaluate the effects of maternal multisensory stimulation on neonatal pain and maternal state anxiety during heel blood collection in neonates. STUDY DESIGN:A randomized controlled trial was conducted from July 2019 to January 2020 in neonatal units, with 80 newborns in intervention(n = 40) and control (n = 40) groups. In the intervention group, mothers provided multisensory stimulation (speech, touch, skin odor, breastfeeding, eye contact), while the control group received routine care. Neonatal Infant Pain Scale (NIPS) and maternal state anxiety inventory were evaluated. RESULTS:NIPS scores and maternal anxiety were significantly lower in the intervention group (p < 0.001). A positive correlation was found between NIPS and maternal anxiety in the intervention group (r = 0.372, p = 0.018). CONCLUSIONS: Maternal multisensory stimulation reduces neonatal pain and maternal anxiety. These findings emphasize the importance of pediatric nurses considering neonatal comfort and maternal emotional well-being during medical procedure. CLINICAL TRIAL REGISTRATION: The protocol for this randomized controlled experimental trial is registered on ClinicalTrials.gov. The clinical trial registration number is https://clinicaltrials.gov; NCT05606458.Article Citation - WoS: 3Citation - Scopus: 3TiO2@ZIF-8 Hybrid as a Type II Heterojunction Photocatalyst:Adsorption/Photocatalytic Properties, Kinetics, and Effect of Humidity(Springernature, 2025) Okte, A. Neren; Tuncel, DuyguTiO2@ZIF-8 hybrid and its humidified forms are synthesized as type 2 heterojunction systems using a facile sol-gel method at different relative humidity (RH) conditions. The hybrids' surface characteristics and optical properties are thoroughly examined, followed by investigations into adsorption capacities and photocatalytic activities using anionic-methyl orange (MO) and cationic-methylene blue (MB) dyes. TiO2@ZIF-8 hybrid generates a mesoporous structure with a higher surface area (135.6 m2 g-1) than bare TiO2 (40.1 m2 g-1). Band gap energies of TiO2@ZIF-8 (3.00 eV) and humidified hybrids (2.95-2.91 eV) decrease compared to the individual phases of TiO2 (3.08 eV) and ZIF-8 (4.9 eV). XPS analysis verifies the electron donation from ZIF-8 to TiO2. Adsorptions of MO and MB differ depending on the affinities of MO or MB's functional groups on the TiO2@ZIF-8 and humidified hybrids. TiO2@ZIF-8 demonstrates 98.7% MO and 89.5% MB degradations within 100 min irradiation. Dark adsorption studies follow Langmuir model with Langmuir constants of KL = 0.445 L mg-1 for MO in the presence of TiO2@ZIF-8 and KL = 0.409 L mg-1 for MB in the presence of TiO2@ZIF-8 (84% RH). Meanwhile, pseudo-second-order kinetic model is applicable for dark experiments with rate constants of k2 = 0.918 g mg-1 min-1 for MO in the existence of TiO2@ZIF-8 and k2 = 0.917 g mg-1 min-1 for MB in the existence of TiO2@ZIF-8 (84% RH). Under irradiation, TiO2@ZIF-8 (84% RH) has higher first-order rate constant 'k' values for both MO (0.0134 min-1) and MB (0.0146 min-1) relative to that of TiO2@ZIF-8 (0.0129 min-1 for MO and 0.0112 min-1 for MB). Based on Langmuir-Hinshelwood model, TiO2@ZIF-8 (84% RH)) shows the highest adsorption coefficients (K) of 0.164 L mg-1 for MO and 0.192 L mg-1 for MB and rate constants (k) of 0.197 mg L-1 min-1 for MO and 0.182 mg L-1 min-1 for MB. Notably, the hybrids maintain high stability and photocatalytic efficiency after four consecutive degradation cycles, highlighting their potential for sustainable environmental remediation.
