Screen media exposure has been increasing in the preschool years. Risky aspects of screen exposure have many potential negative effects on children's health. We aimed to evaluate problematic screen ...exposure in Turkish preschool children by using a unique tool called the "Seven-in-Seven Screen Exposure Questionnaire" and to investigate factors associated with problematic screen exposure.
A questionnaire form was designed including general descriptive questions in the first part. In the second part, a questionnaire we designed called the "Seven-in-Seven Screen Exposure Questionnaire" was conducted to evaluate problematic screen exposure characteristics. The questionnaire included seven items: daily screen time, viewing with parent(s), setting screen limits, screen exposure during meals and in the hour before bedtime, age of onset of screen exposure, and viewing low-quality content. The total problematic screen exposure score (range 0-13) was generated by summing scores from the seven items. Total scores are classified into two categories: low (< 7) and high (≥ 7). Logistic regression was performed to search for independent parameters associated with problematic screen exposure.
One thousand two hundred forty-five mother-child pairs participated in this study. The median age of the children was 3.9 (IQR: 2.9-4.7) years and 51% were males. Overall, 280 children (22.5%) had a problematic screen exposure score of ≥7 (high). The median problematic screen exposure score was 4 (IQR: 3-6). Maternal age of < 30 years; paternal age of ≥30 years; maternal educational level of ≤12 years; the age of 24-48 months; home-based daycare; postponing eating, toileting, or sleeping while using a screen; and using touchscreen devices were found to be associated with an increased risk of having a high problematic screen exposure score.
Developing national scales to monitor problematic screen use in children would be more effective than monitoring screen time alone. All of the screen use characteristics not recommended in children would be evaluated using problematic screen exposure scales. The "Seven-in-Seven Screen Exposure Questionnaire" may serve as an example for further studies.
We aimed to investigate the video game habits and their relationship with home environment in children 2-5 years in Turkey. A structured questionnaire about the child's demographic, screen, and video ...gaming characteristics was completed by parents in five health centers from three provinces. One-quarter of 1245 preschoolers were found to play video games. The prevalence of playing video games was higher in older age, male gender, low parental education, families with 3 or more children, having a game console, computers and tablets at home, child's screen time of more than 2 hours per day, child's non-compliance with the parental screen rules, and presence of someone else playing videogame at home. Of the parents, 54.5% did not know the name of the video game the child was playing. Parents should be counseled about supervising on their children's video game playing habits and selection of well-designed games with the right content.
The open-label, phase II RECORD-2 trial compared efficacy and safety of first-line everolimus plus bevacizumab (EVE/BEV) with interferon plus bevacizumab (IFN/BEV) in patients with metastatic renal ...cell carcinoma.
Previously untreated patients were randomized 1:1 to bevacizumab 10 mg/kg every 2 weeks with either everolimus 10 mg/day (EVE/BEV) or interferon (9 MIU 3 times/week, if tolerated) (IFN/BEV). Tumor assessments occurred every 12 weeks. The primary objective was the assessment of treatment effect on progression-free survival (PFS), based on an estimate of the chance of a subsequent phase III trial success (50% threshold for phase II success).
Baseline characteristics were balanced between the EVE/BEV (n = 182) and IFN/BEV (n = 183) arms. The median PFS was 9.3 and 10.0 months in the EVE/BEV and IFN/BEV arms, respectively (P = 0.485). The predicted probability of phase III success was 5.05% (hazard ratio = 0.91; 95% confidence interval 0.69–1.19). The median duration of exposure was 8.5 and 8.3 months for EVE/BEV and IFN/BEV, respectively. The percentage of patients discontinuing because of adverse events (AEs) was 23.4% for EVE/BEV and 26.9% for IFN/BEV. Common grade 3/4 AEs included proteinuria (24.4%), stomatitis (10.6%), and anemia (10.6%) for EVE/BEV and fatigue (17.1%), asthenia (14.4%), and proteinuria (10.5%) for IFN/BEV. The median overall survival was 27.1 months in both arms.
The efficacy of EVE/BEV and IFN/BEV appears similar. No new or unexpected safety findings were identified and, with the exception of proteinuria in about one-fourth of the population, EVE/BEV was generally well tolerated.

We aimed to evaluate 14 urinary phthalate metabolites and 4 toxic metals in adolescents having thyroid colloid cyst (TCC) and compare with age and sex-matched others without TCC. Phthalate ...metabolites were analysed with UPLC-MS/MS and heavy metals with ICP-MS. TCC ratios in tertile subgroups of pollutants were compared with multiple logistic regression analysis after adjusting for age, sex, z-scores for body mass index and urinary creatinine values. Adolescents having the highest tertile of mono (2-ethylhexyl) phthalic acid and mercury had increased odds and those with the highest tertiles of monocarboxy-isononyl phthalate, mono (3-carboxypropyl) phthalate, monoisobutyl phthalate had lower odds for TCC than counterparts. The odds of TCC were lower for those in the second and the third tertiles. No differences in TCC ratios were detected with other pollutants. Given phthalate esters' and toxic metals' specific interactions on TCC, further studies were necessary to assess the influence of chemicals on TCC.
is an ideal third-generation biofuel source due to its ability to produce transesterified lipids. While nanofer 25s zero-valent iron nanoparticles (nZVIs) improve lipid production, an imbalance ...between reactive oxygen species (ROS) and cellular defense can be catastrophic to the organism. In the present study, the effect of ascorbic acid on nZVI and UV-induced stress in
strain B481-SD was investigated, and lipid profiles in the combination regimen of nZVIs and ascorbic acid compared. Comparison of
growth in BG11 media amended with 2, 4, 6, 8, and 10 mM ascorbic acid indicated 6 mM to be optimal for the growth of B481-SD. Further, growth in 6 mM ascorbic acid combined with 3.2 mg/L nZVIs was significantly higher when compared to the combination regimen of 12.8 and 51.2 mg/L of nZVIs and 6 mM ascorbic acid. The reversal effect of UV-B radiation for 30 min and 1 h indicated that ascorbic acid restored B481-SD growth. Transesterified lipids characterized by gas chromatography-mass spectrometry indicated C16 hexadecanoate to be the most abundant fatty acid methyl ester in the combination regimen of 6 mM ascorbic acid and 12.8 mg/L nZVI-treated
. These findings were supported by microscopic observations in which cellular degradation was observed in B481-SD cells treated with 6 mM ascorbic acid and 12.8 mg/L nZVIs. Our results indicate that ascorbic acid counteracts the damaging effect of oxidative stress produced by nZVIs.
Conventional chemotherapy is the most valid method to cope with cancer; however, it has serious drawbacks such as decrease in production of blood cells or inflammation of the lining of the digestive ...tract. These side effects occur since generally the drugs used in chemotherapy are distributed evenly within the body of the patient and cannot distinguish the cancer cells from the healthy ones. In this study, folic acid (FA)-conjugated, polyethylene-coated magnetic nanoparticles (FA-MNPs), and doxorubicin (Dox)-loaded formulation (Dox-FA-MNPs) were prepared. The cytotoxicity of these nanoparticles on HeLa and Dox-resistant HeLa cells was investigated. Magnetic nanoparticles (MNPs), polyethylene glycol (PEG)-coated MNPs (PEG-MNPs), and FA-MNPs were successfully synthesized and characterized by several methods. Dox loading of FA-MNPs and release profile of Dox from the nanoparticles were studied. Cytotoxic effects of FA-MNPs and Dox-FA-MNPs on HeLa cells were analyzed. MNPs, PEG-MNPs, and FA-MNPs all had small sizes and supermagnetic behavior. High amounts of Dox could be loded onto the nanoparticles (290 μgmL−1). In 24 h, 15.7% of Dox was released from the Dox-FA-MNPs. The release was increased in acidic conditions (pH 4.1). Internalization studies showed that FA-MNPs and Dox-FA-MNPs were taken up efficiently by HeLa cells. The investigation of cytotoxicity of the particles indicated that 38–500 μgmL−1 Dox-FA-MNPs significantly decreased the proliferation of HeLa cells compared to FA-MNPs. Due to their size, magnetic properties, internalization, drug release, and cytotoxicity characteristics, the MNPs prepared in this study may have potential application as a drug delivery system in cancer chemotherapy.
1. This study evaluated the effect of a higher incubation temperature on body weight, plasma profile, histology and expression of myogenin (MYOG), insulin-like growth factor-I (IGF-I) and vascular ...endothelial growth factor A (VEGFA) genes in breast muscle of embryos and broilers from two commercial strains.
2. A total of 784 eggs from Ross 308 and Cobb 500 broiler breeder flocks were used. Half of the eggs per strain were incubated at control temperature (37.8°C), whereas the other half were exposed to heat treatment (HT) of 38.8°C between embryonic day (ED) 10 and 14, for 6 h/day. Embryos and chicks were sampled on ED 19 and at hatch. A total of 480, one-day-old chicks per strain and incubation temperature were reared up to 42 d post-hatch.
3. The HT increased hatch weight of Ross chicks and 42-d body weight of broilers from both strains. Lower plasma triacylglycerol levels were measured for HT embryos and broilers on ED 19 and 42 d post-hatch, respectively. HT reduced plasma T

levels in Ross embryos and broilers for the same periods. Hepatic TBARS concentrations were elevated by HT compared to the control incubation.
4. The HT reduced breast muscle VEGFA gene expression of Cobb embryos on ED 19, whereas expression was stimulated in day-old chicks. At 42 d post-hatch, fibre area was increased by HT regardless of strain. Compared to the control incubation, HT increased the breast yield of Ross broilers and leg yield of Cobb. Ross-HT broilers had a higher pH at 24 h after slaughter and better water holding capacity than Cobb-HT broilers.
5. These results suggested that HT increased body weight, fibre area, IGF-I gene expression and lowered plasma triacylglycerol levels of broiler chickens from both strains at 42 d. However, HT influenced the expression of VEGF-A and MYOG genes and meat quality differently between the broiler strains.
The most common type of burn among children is scalding burn. This study aims to reveal child abuse and neglect as a specific etiological factor that specific to our country, traditional teapot- and ...teacup-related scalding burns. Burn cases that admitted to our Burn Center were investigated, and among these, 72 cases suffering from scalding burns were included in the study. The interview forms issued upon admission of these cases were evaluated in detail. Out of 148 scalding burn cases, 48.6% were related to the use of traditional teapots and teacups. After a detailed assessment, all cases were considered neglect-related burns. As a result of considering the role of traditional teapots and teacups in pediatric injuries in our country, parents and caregivers should be warned about these types of injuries. Also, physicians must determine the possibility of child abuse or neglect in all pediatric burn cases.
Background
Although the immune checkpoint inhibitors (ICIs) became a vital part of cancer care, many patients do not respond to treatment, indicating need for biomarkers. The Pan-Immune-Inflammation ...Value (PIV) is a recently developed peripheral blood count-based biomarker. Herein, we evaluated a PIV-based candidate scoring system as a prognostic biomarker in ICI-treated patients.
Methods
A total of 120 advanced cancer patients treated with anti-PD-1 or anti-PD-L1 inhibitors for any cancer type were included in this study. The PILE scoring system incorporating the PIV (< median vs. ≥ median), lactate dehydrogenase levels (normal vs. > normal) and Eastern Cooperative Oncology Group performance status (0 vs. ≥ 1) was constructed from the multivariate analyses and used for stratification. The association between overall survival (OS), progression-free survival and PILE risk category was evaluated with multivariate analysis.
Results
The median follow-up was 9.62 months and the median OS of all cohort were 12.42 ± 2.75 months. Patients with higher PIV had significantly decreased OS (7.75 ± 1.64 vs. 18.63 ± 4.26 months,
p
= 0.037). The patients in the PILE high-risk group (PILE score 2–3) had decreased OS (18.63 ± 4.02 vs. 5.09 ± 1.23 months, HR: 2.317, 95% CI: 1.450–3.700,
p
< 0.001) and PFS (7.69 ± 1.30 vs. 2.69 ± 0.65 months, HR: 1.931, 95% CI: 1.263–2.954,
p
= 0.002) compared to PILE low-risk group (PILE score 0–1). The Harrell C-Index values were 0.65 and 0.61 for OS and PFS prediction, respectively.
Conclusion
In this study, we demonstrated a decreased overall survival in ICI-treated patients with a higher PILE score. If prospective studies validate our results, PILE score could be a biomarker for immunotherapy.
