Effects of different toothpastes on the color and whiteness of stained anterior composite resin.

PURPOSE: To evaluate changes in the color of an anterior nanohybrid composite resin and differences in its whitening index after 30 days of brushing with six brands of whitening toothpaste in vitro to simulate the situation in individuals with high coffee consumption. METHODS: Eighty-four disk-shaped resin specimens were prepared (shade A2). For initial staining, the samples were immersed in coffee solution for 14 days and then divided into eight groups for treatment with various toothpastes. Color was assessed at the baseline, after initial staining, and on days 7, 14, and 30 of the staining-and-brushing cycle. Color stability was evaluated based on the CIEDE2000 color difference (ΔE00), and differences in whiteness were determined using the whitening index for dentistry (WID). RESULTS: The highest ΔE00 and ΔWID values were obtained with Colgate Herbal, followed by Opalescence Whitening and Crest Baking Soda and Peroxide, whereas the lowest values were obtained with distilled water, followed by Yotuel Pharma B5, on day 30 of the staining-and-brushing cycle. CONCLUSION: In terms of improving the color and whiteness of coffee-stained anterior nanohybrid composite resin, Colgate Herbal, Opalescence Whitening, and Crest Baking Soda and Peroxide yielded promising results after 30 days of continuous use.

Comparing therapeutic effects of alternate day versus daily oral iron in women with iron deficiency anemia: A retrospective cohort study.

In order to replenish iron stores and bring hemoglobin (Hb) levels back to normal, oral iron is the primary treatment option for women with iron deficiency anemia (IDA). This study investigated the efficacy and side effects of daily versus alternate-day, given single doses versus double doses oral iron supplementation for treating IDA. A retrospective cohort study was performed between 2021 and 2022, including 120 patients. Study group were divided into 4 age-sex-matched groups; Group I (n = 30) and Group II (n = 30) which were received ferrous sulphate tablets daily in single or double doses, respectively, containing 60 mg of elemental iron each. Groups III (n = 30) and IV (n = 30) were received a single and double dose on alternate days, respectively. The primary outcome was the mean difference in Hb from baseline at week 4. Gastrointestinal (GI) side effects were accepted as a secondary outcome. The daily single dose and alternate day double dose groups had median Hb changes of 2.3 (2.1) and 2.6 (1.8) g/dL. The differences in Hb between Groups I and II, I and III, and Groups IV and II, IV and III were significant (P < .001, P = .001, P < .001, and P < .001, respectively). There is no significant difference between groups regarding improving iron parameters such as serum iron, total iron binding capacity, transferrin saturation, and ferritin. The incidence of GI side effects were greater in double doses than in single doses of daily or alternate-day therapies (43.3% and 30% vs 10% and 3.3%). Daily or alternate-day double dose resulted in more side effects but less therapeutic efficacy in women with IDA. To find the best supplementation method, randomized controlled trials with a larger sample of participants, longer study lengths, and various iron doses may be helpful.

Therapeutic effects of vitamin D and IL-22 on methotrexate-induced mucositis in mice.

Mucositis is a common side effect of cancer therapies and transplant conditioning regimens. Management of mucositis involves multiple approaches from oral hygiene, anti-inflammatory, anti-apoptotic, cytoprotective, and antioxidant agents, to cryo-therapy, physical therapy, and growth factors. There is room for novel, affordable treatment options, or improvement of currently available therapies. Vitamin D has been shown to regulate mucosa-resident cell populations such as Th17 or innate lymphoid cells and critical mucosal cytokine IL-22; however, their therapeutic potential has not been put to test in preclinical mouse models. In this study, we aimed to test the therapeutic potential of vitamin D injections and IL-22 overexpression in a murine model of chemotherapy-induced mucositis. Balb/c mice were given daily intraperitoneal injections of vitamin D. Mucositis was induced by methotrexate. Another group received IL-22 plasmid via hydrodynamic gene delivery. Weight loss and intestinal histopathology, intestinal levels of cytokines IL-22, IL-17A, GM-CSF, IL-23, IFN-γ, TNF-α, and IL-10, and number of intestinal lamina propria B cell, neutrophil, and total innate lymphoid cells were quantified. Daily vitamin D injections ameliorated intestinal inflammation and elevated intestinal IL-22 levels compared with control groups. Temporal overexpression of IL-22 by hydrodynamic gene delivery slightly increased intestinal IL-22 but failed to confer significant protection from mucositis. To our knowledge, this is the first experimental demonstration in an animal model of mucositis of therapeutic use of vitamin D and IL-22 supplementation and our results with vitamin D suggest it may have merit in further trials in human mucositis patients.

The Determination of the Efficacy of Neural Therapy in Conservative Treatment-resistant Patients with Chronic Low Back Pain.

STUDY DESIGN: A randomized clinical trial. OBJECTIVE: The aim of this article is to determine the effectiveness of neural therapy (NT) in patients with chronic low back pain (LBP) who are resistant to medical and physical therapies. SUMMARY OF BACKGROUND DATA: Patients with LBP generally respond well to the treatment, whereas some cases do not improve via medical and physical therapies. Although trigger point injections (TPIs) may be an effective short-term treatment in selected patients with LBP, they are not recommended in patients with chronic LBP due to a long-lasting benefit not being demonstrated. METHODS: Fifty patients, who had inadequate functional recovery and pain relief, with chronic LBP were randomly divided into two groups: Group 1, only single TPI; Group 2, NT. NT including local-segmental treatment (intradermal injections) on the lumbosacral region, 5 M injection (intradermal injections of the projection of the pelvic organs on the suprapubic region), pelvic plexus injection, i.v. injection (2 mL) for five sessions per a week. All patients in group 2 received the same kind of intervention every seance but interference field injections (injections into umbilicus for all patients and injections into scars resulting from vaccination and surgical operations such as cesarean section, if any) were also applied at the only first seance. The Visual Analog Scale (VAS) scores for current pain during activities and Roland Morris Disability Questionnaire (RMDQ) scores for disability were recorded at baseline and 1, 3, 6 months post-injection. RESULTS: The VAS and RMDQ scores at 3 and 6 months were significantly lower in Group 2 versus Group 1 (P < 0.05). CONCLUSION: NT may be an alternative treatment option in patients with chronic LBP for pain relief and functional recovery in the long run.Level of Evidence: 2.

Dietary supplementation of black mulberry (Morus nigra) syrup improves the growth performance, innate immune response, antioxidant status, gene expression responses, and disease resistance of Nile tilapia (Oreochromis niloticus).

The present study investigated the effects of black mulberry (Morus nigra) syrup supplementation on growth performance, hematological, serum biochemical, innate immune parameters, immune and antioxidant related gene expression responses, and disease resistance of Nile tilapia, Oreochromis niloticus. Five isonitrogenous and isoenergetic diets were formulated to contain black mulberry syrup at levels of 0%, 0.75%, 1.5%, 2.0%, and 3.0%. Fish were fed experimental diets for 60 days. Dietary black mulberry syrup increased activities of serum lysozyme, myeloperoxidase, superoxide dismutase and catalase, and increased the expression levels of immune-related genes (interleukin 1, beta, tumor necrosis factor, immunoglobulin M, interferon gamma and heat shock protein 70) in the spleen and antioxidant-related genes (superoxide dismutase, catalase and glutathione peroxidase) in the liver of fish fed especially with 1.5%, 2.0%, and 3.0% black mulberry syrup supplemented diets. Furthermore, at 2.0% incorporation level, growth performance increased. The findings of the present study indicate that Nile tilapia fed with diet containing 2.0% black mulberry might be adequate to improve the growth performance, innate immune parameters, antioxidant related gene expression responses, and disease resistance against Aeromonas veronii.

Complementary and Alternative Medicine Methods Used Among Turkish Pediatric Oncology Patients.

PURPOSE: Complementary and alternative medicine (CAM) methods are gradually becoming common in pediatric oncology. The aim of this study was to determine the current use of CAM methods by Turkish mothers for their children with cancer. DESIGN AND METHODS: The sample for this descriptive and cross-sectional study consisted of the mothers (n = 110) of children with cancer undergoing treatment in a hematology-oncology clinic and outpatient clinic. The data were collected using a questionnaire that included the CAM methods used by mothers for their children with cancer. RESULTS: Of 110 children, 65 (59.1%) were diagnosed with leukemia and 107 (97.3%) underwent chemotherapy. More than half of the mothers (53.6%) were using CAM methods. The most common CAM method was the use of natural products (93.2%), of which the most frequently used were carob, mulberry, and grape molasses. Mothers used CAM to support the treatment of their children with cancer and alleviate the side effects of chemotherapy and, in most cases, without previously consulting healthcare professionals about their use. CONCLUSIONS: This study revealed that most mothers used CAM methods for their children. PRACTICE IMPLICATIONS: It is important that healthcare professionals are aware about the use of CAM methods in children with cancer to prevent any possible negative interaction between conventional (i.e., chemotherapy) and alternative treatments.

Effects of dietary anthocyanin on innate immune parameters, gene expression responses, and ammonia resistance of Nile tilapia (Oreochromis niloticus).

The present study investigated the effects of dietary anthocyanin on the growth performance, haematological, non-specific immune, and spleen gene expression responses of Nile tilapia, Oreochromis niloticus. Five experimental groups of fish with mean weights of 8.24 ±â€¯0.64 g were used in the study; four of these were fed with diets incorporating anthocyanin (20 mg kg -1, 40 mg kg-1, 80 mg kg-1 and 160 mg kg-1), while the fifth was a control group without dietary anthocyanin. Growth performance and haematological parameters of tilapia were not affected by anthocyanin-supplemented diets (p > 0.05). Dietary anthocyanin significantly increased respiratory burst activity, phagocytic activity, phagocytic index, lysozyme activity, myeloperoxidase activity, serum total superoxide dismutase (T.SOD) activity, and serum catalase (CAT) activity (p < 0.05). The total immunoglobulin level was highest in the 80 mg kg-1 group compared with the other groups (p < 0.05). In addition, with the anthocyanin-containing diets, the gene levels of interleukin 1, beta (IL-1ß), interleukin 8 (IL-8), tumor necrosis factor (TNF-α), heat shock protein 70 (HSP70), and interferon gamma (IFN-γ) were increased in the fish spleen, and the gene levels of CAT, GPx, and SOD were also increased in fish liver (p < 0.05). At the end of the experiment, the fish were subjected to ammonia stress. The groups fed with 20 and 40 mg kg-1 anthocyanin exhibited higher survival rates than the other groups. In summary, feeding Nile tilapia with anthocyanin-containing diets caused increases in the innate immune parameters, gene expression responses, and the survival rate of the fish subjected to ammonia stress.

Effects of nutritional vitamin D supplementation on markers of bone and mineral metabolism in children with chronic kidney disease.

Background: We investigated the effects of nutritional vitamin D supplementation on markers of bone and mineral metabolism, i.e. serum levels of fibroblast growth factor 23 (FGF23), Klotho, bone alkaline phosphatase (BAP) and sclerostin, in two cohorts with chronic kidney disease (CKD). Methods: In all, 80 vitamin D-deficient children were selected: 40 with mild to moderate CKD from the ERGO study, a randomized trial of ergocalciferol supplementation [estimated glomerular filtration rate (eGFR) 55 mL/min/1.73 m2], and 40 with advanced CKD from the observational Cardiovascular Comorbidity in Children with Chronic Kidney Disease (4C) study (eGFR 24 mL/min/1.73 m2). In each study, vitamin D supplementation was started in 20 children and 20 matched children not receiving vitamin D served as controls. Measures were taken at baseline and after a median period of 8 months. Age- and gender-related standard deviation scores (SDSs) were calculated. Results: Before vitamin D supplementation, children in the ERGO study had normal FGF23 (median 0.31 SDS) and BAP (-0.10 SDS) but decreased Klotho and sclerostin (-0.77 and -1.04 SDS, respectively), whereas 4C patients had increased FGF23 (3.87 SDS), BAP (0.78 SDS) and sclerostin (0.76 SDS) but normal Klotho (-0.27 SDS) levels. Vitamin D supplementation further increased FGF23 in 4C but not in ERGO patients. Serum Klotho and sclerostin normalized with vitamin D supplementation in ERGO but remained unchanged in 4C patients. BAP levels were unchanged in all patients. In the total cohort, significant effects of vitamin D supplementation were noted for Klotho at eGFR 40-70 mL/min/1.73 m2. Conclusions: Vitamin D supplementation normalized Klotho and sclerostin in children with mild to moderate CKD but further increased FGF23 in advanced CKD.

Cardiovascular Phenotypes in Children with CKD: The 4C Study.

BACKGROUND AND OBJECTIVES: Cardiovascular disease is the most important comorbidity affecting long-term survival in children with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The Cardiovascular Comorbidity in Children with CKD Study is a multicenter, prospective, observational study in children ages 6-17 years old with initial GFR of 10-60 ml/min per 1.73 m2. The cardiovascular status is monitored annually, and subclinical cardiovascular disease is assessed by noninvasive measurements of surrogate markers, including the left ventricular mass index, carotid intima-media thickness, and central pulse wave velocity. We here report baseline data at study entry and an explorative analysis of variables associated with surrogate markers. RESULTS: A total of 737 patients were screened from October of 2009 to August of 2011 in 55 centers in 12 European countries, and baseline data were analyzed in 688 patients. Sixty-four percent had congenital anomalies of the kidney and urinary tract; 26.1% of children had uncontrolled hypertension (24-hour ambulatory BP monitoring; n=545), and the prevalence increased from 24.4% in CKD stage 3 to 47.4% in CKD stage 5. The prevalence of left ventricular hypertrophy was higher with each CKD stage, from 10.6% in CKD stage 3a to 48% in CKD stage 5. Carotid intima-media thickness was elevated in 41.6%, with only 10.8% of patients displaying measurements below the 50th percentile. Pulse wave velocity was increased in 20.1%. The office systolic BP SD score was the single independent factor significantly associated with all surrogate markers of cardiovascular disease. The intermediate end point score (derived from the number of surrogate marker measurements >95th percentile) was independently associated with a diagnosis of congenital anomalies of the kidney and urinary tract, time since diagnosis of CKD, body mass index, office systolic BP, serum phosphorus, and the hemoglobin level. CONCLUSIONS: The baseline data of this large pediatric cohort show that surrogate markers for cardiovascular disease are closely associated with systolic hypertension and stage of CKD.

Genetic, Environmental, and Disease-Associated Correlates of Vitamin D Status in Children with CKD.

BACKGROUND AND OBJECTIVES: Vitamin D deficiency is endemic in children with CKD. We sought to investigate the association of genetic disposition, environmental factors, vitamin D supplementation, and renal function on vitamin D status in children with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Serum 25-hydroxy-vitamin D, 1,25-dihydroxy-vitamin D, and 24,25-dihydroxy-vitamin D concentrations were measured cross-sectionally in 500 children from 12 European countries with CKD stages 3-5. All patients were participants of the Cardiovascular Comorbidity in Children with Chronic Kidney Disease Study, had CKD stage 3-5, and were age 6-18 years old. Patients were genotyped for single-nucleotide polymorphisms in the genes encoding 25-hydroxylase, vitamin D binding protein, 7-dehydrocholesterol reductase, and 24-hydroxylase. Associations of genetic status, season, local solar radiation, oral vitamin D supplementation, and disease-associated factors with vitamin D status were assessed. RESULTS: Two thirds of patients were vitamin D deficient (25-hydroxy-vitamin D <16 ng/ml). 25-Hydroxy-vitamin D concentrations varied with season and were twofold higher in vitamin D-supplemented patients (21.6 [14.1] versus 10.4 [10.1] ng/ml; P<0.001). Glomerulopathy, albuminuria, and girls were associated with lower 25-hydroxy-vitamin D levels. 24,25-dihydroxy-vitamin D levels were closely correlated with 25-hydroxy-vitamin D and 1,25-dihydroxy-vitamin D (r=0.87 and r=0.55; both P<0.001). 24,25-dihydroxy-vitamin D concentrations were higher with higher c-terminal fibroblast growth factor 23 and inversely correlated with intact parathyroid hormone. Whereas 25-hydroxy-vitamin D levels were independent of renal function, 24,25-dihydroxy-vitamin D levels were lower with lower eGFR. Vitamin D deficiency was more prevalent in Turkey than in other European regions independent of supplementation status and disease-related factors. Single-nucleotide polymorphisms in the vitamin D binding protein gene were independently associated with lower 25-hydroxy-vitamin D and higher 24,25-dihydroxy-vitamin D. CONCLUSIONS: Disease-related factors and vitamin D supplementation are the main correlates of vitamin D status in children with CKD. Variants in the vitamin D binding protein showed weak associations with the vitamin D status.

Intracranial hemorrhage in infants as a serious, and preventable consequence of late form of vitamin K deficiency: a selfie picture of Turkey, strategies for tomorrow.

PURPOSE: Vitamin K deficiency bleeding is one of the most common causes of acquired hemostatic disorder in early infancy. Although vitamin K is practiced routinely after every birth in Turkey, children with type of vitamin K deficiency bleedings (L-VKDB) can be encountered. We aimed to evaluate the clinical features of the children with L-VKDB reported from Turkey. METHODS: Between 1995 and 2013, 48 studies reporting 534 children with L-VKDB were evaluated in this study. RESULTS: Of the 534 reported children (178 girls, 356 boys), 486 (91 %) were extremely breastfed. The most common bleeding sites were intracranial hemorrhage, gastrointestinal, and umbilical in 414 (77.4 %), 33 (6.2 %), and 33 (6.2 %) children, respectively, and 35 (6.6 %) children had been diagnosed incidentally without any bleeding. The etiology of 399 (74.7 %) children were classified as idiopathic, whereas 135 (25.3 %) were secondary. Intramuscular vitamin K was administered in 248 (46.4 %), not administered in 228 (42.7 %), and the administration of vitamin K were not determined in 58 (10.9 %) children. The outcomes of Turkish cohort showed that 111 (20.8) children died, 257 (48.1 %) cases developed neurologic deficit (mainly epilepsy and psychomotor retardation), and only 166 (31.1 %) patients recovered without squeal. CONCLUSIONS: The compliance of prophylactic measures in Turkey does not seem to be satisfactory. As a further measure of tomorrow, we vigorously emphasize that a national surveillance program may be initiated. An additional intramuscular dose or oral supplementation of vitamin K especially for exclusively breast-fed infants may reduce this catastrophic problem in our country.
