Association between novel inflammatory markers derived from hemogram indices and metabolic parameters in type 2 diabetic men.

AIM: Hemogram indices were proposed as novel inflammatory markers in chronic conditions and inflammation has substantial role in the pathogenesis of type 2 diabetes mellitus (T2DM). We aimed to observe hemogram parameters of type 2 diabetic male subjects with various age groups in well and poorly controlled subsets. METHODS: Data of type 2 diabetic men enrolled to the study were recorded from patient files of the institution. Study population were grouped into three according to the age. Group A was consisted of patients younger than 55 years, Group B was consisted of patients aged between 55 and 64 years, and Group C was consisted of patients aged 65 years or older. Data of the study groups were compared. RESULTS: Study population was consisted of 130 subjects; 44 in Group A and 43 in each of Groups B and C. Median red cell distribution width (RDW) (p = .04), mean RDW to platelet ratio (RPR) (p = .006), median mean platelet volume to platelet ratio (MPR) (p = .02) levels of the study groups were statistically different. HbA1c level was significantly and positively correlated with RDW (r = 0.45, p < .001), neutrophil to lymphocyte ratio (NLR) (r = 0.47, p < .001), mean platelet volume to lymphocyte ratio (MLR) (r = 0.35, p < .001), MPR (r = 0.26, p = .003), and RPR (r = 0.37, p < .001) levels. CONCLUSION: Elevated RDW, NLR, MLR, MPR, and RPR levels in diabetic men should trigger the measurement of HbA1c since each were strongly correlated with HbA1c level. Moreover, elevated RDW, NLR, MLR, and RPR could be marker of worse diabetic control in men with T2DM.

Type 2 diabetes mellitus is more commonly well controlled in younger men compared to older men.

METHODS: The male patients with T2DM that admitted to the outpatient internal medicine clinics of our institution between November 2018 and April 2019 were included to the study. According to the age, study population divided into two groups; either younger than 60 years (group I) and 60 years or older (group II). Study parameters were compared between study groups. RESULTS: Fasting plasma glucose (FPG) and glycated Hb level (HbA1c) of group I were lower than those of the group II (p = 0.004 for FPG and p = 0.048 for HbA1c). Control level of T2DM was defined as well controlled in 20 (29%) patients in group I and 5 (10.9%) patients in group II (p = 0.02). CONCLUSION: Physicians should aware that well controlled T2DM is more common among younger diabetic men compared to older men and try to enhance diabetic regulation level in elderly men by interventions that aimed to improve skeletal muscle or by pharmacologic agents.

Efficacy of novel albendazole salt formulations against secondary cystic echinococcosis in experimentally infected mice.

In this study, we evaluated the efficacy, expressed as a mean weight decrease of the whole echinococcal cyst mass, of novel benzimidazole salt formulations in a murine Echinococcus granulosus infection model. BALB/c mice were intraperitoneally infected with protoscoleces of E. granulosus (genotype G1). At 9 months post-infection, treatment with albendazole (ABZ), ricobendazole (RBZ) salt formulations, and RBZ enantiomer salts (R)-(+)-RBZ-Na and (S)-(-)-RBZ-Na formulations were initiated. Drugs were orally applied by gavage at 10 mg kg-1 body weight per day during 30 days. Experimental treatments with benzimidazole sodium salts resulted in a significant reduction of the weight of cysts compared to conventional ABZ treatment, except for the (S)-(-)-RBZ-Na enantiomer formulation. Scanning electron microscopy and histological inspection revealed that treatments impacted not only the structural integrity of the parasite tissue in the germinal layer, but also induced alterations in the laminated layer. Overall, these results demonstrate the improved efficacy of benzimidazole salt formulations compared to conventional ABZ treatment in experimental murine cystic echinococcosis.

THE ASSOCIATION BETWEEN VITAMIN D LEVELS AND HANDGRIP STRENGTH IN ELDERLY MEN.

CONTEXT: Vitamin D is a steroid hormone that acts by binding to the vitamin D receptor (VDR) found in many tissues. According to the long-term mechanism, vitamin D causes the proliferation and differentiation of muscle cells by gene transcription. OBJECTIVE: We aimed to evaluate the relationship between muscle strength and serum vitamin D levels in elderly men. DESIGN: Cross-sectional study. SUBJECTS AND METHODS: Male patients over age 50 were included in the study. Study population was divided into 2 groups with handgrip strength according to body mass index, either as subjects with weak or with normal handgrip strength test (HGST). Vitamin D levels and other variables compared between weak and normal groups. RESULTS: Vitamin D level of weak and normal groups were 7.5 (3-19.9) µg/L, and 11.6 (11.6-34.9) µg/L, which means significant reduced vitamin D levels in weakness group (p=0.01). Vitamin D levels were significantly correlated with HGST levels (r:0.362, p=0.001). Vitamin D levels were found to be an independent predictor of weakness according to HGST in logistic regression analysis (OR: 0.453, 95% Cl:0.138-0.769, p=0.05). CONCLUSIONS: Low vitamin D level is an independent risk factor for muscle weakness in men aged more than 50 years. Therefore, vitamin D levels should be screened and early replacement should be initiated for the sake of improvement of muscle strength in elderly subjects that vulnerable for frailty.

THE EFFECT OF ANTITHYROID DRUGS ON OSTEOPONTIN AND OXIDATIVE STRESS IN GRAVES' DISEASE.

OBJECTIVE: The aim of the present study is to evaluate the effects of methimazole (MTZ) and propylthiouracil (PTU) treatments on osteopontin (OPN) and oxidative stress in Graves' disease (GD). MATERIAL AND METHODS: The study included 60 cases with GD in hyperthyroid state and taking no antithyroid treatment, and 30 healthy volunteers. GD patients were randomly separated into two groups; 30 of them took PTU, and the other 30 took MTZ treatments. Blood samples were taken from the patients with GD before the treatment, and three months after the treatment was begun, when they were in the euthyroid state; blood samples of the healthy control subjects were also taken at these times. RESULTS: TAS and OSI levels before treatment were significantly higher in the GD group, when compared to the control group (p<0.001, for each). GD subjects taking PTU treatment had significantly higher TAS levels (p=0.001), and significantly lower TOS and OSI levels (p=0.008 and p=0.001, respectively). TAS levels significantly decreased in the patients taking MTZ treatment (p=0.029), but TOS and OSI levels did not change significantly (p>0.05). Pretreatment OPN levels were significantly higher in GD patients, when compared to the control group (p=0.014). OPN level significantly decreased in the GD group taking PTU treatment; however OPN levels in the group taking MTZ treatment did not change significantly when compared to the pretreatment value. CONCLUSION: PTU treatment is more effective in decreasing OPN and oxidative stress in GD patients, when compared to the MTZ treatment.

Association of prenatal folate status with early childhood wheeze and atopic dermatitis.

BACKGROUND: Prenatal folic acid supplementation is recommended to prevent birth defects. Some foods are fortified in the USA to ensure sufficient intake among reproductive-aged women. However, high prenatal folate exposure may be a risk factor for childhood atopic diseases. We investigated associations between prenatal folate and early childhood wheeze and atopic dermatitis in a US cohort. METHODS: We studied 858 mother-child dyads, enrolled prenatally. Folate was measured in 2nd and 3rd trimester maternal plasma. Parents reported current wheeze (previous 12 months) and healthcare provider diagnosis of atopic dermatitis at 3 years. We examined associations using logistic regression, modeling folate continuously and dichotomously (< or ≥20 ng/mL), a level often considered supraphysiologic. RESULTS: Over half of women were African American and on Medicaid. Median (interquartile range) folate levels were 22.6 (15.9-30.0) and 23.1 (16.1-30.0) ng/mL for 2nd and 3rd trimesters, respectively. Current wheeze and atopic dermatitis were reported for 20.4% and 26.8% of children, respectively. Second trimester folate as a continuous exposure was not significantly associated with outcomes. Decreased odds of current wheeze were observed in children born to mothers who had 2nd trimester folate ≥20 ng/mL (adjusted odds ratios = 0.67, 95% confidence interval = 0.46, 0.97) compared to children with maternal levels <20 ng/mL. Third trimester folate was not associated with outcomes. CONCLUSIONS: High plasma folate in mid-pregnancy was associated with decreased odds of current wheeze at age 3. Our findings do not support harmful effects of high prenatal folate levels on childhood atopic diseases in this setting.

Pregnancy-driven cardiovascular maternal miR-29 plasticity in obesity.

BACKGROUND: Obesity in pregnancy (MO) is a risk factor for maternal and/or fetal cardiovascular system disorders. This study evaluated maternal CVS expression of microRNA-29 family and its target molecules in MO to test the hypotheses: CVS miR-29 concentrations are increased in pregnancy and decreased in MO. METHODS: Non-pregnant (n=4), pregnant obese (POb, n=4), and pregnant non-obese (PnOb, n=4) baboons (Papio spp.) were studied. Maternal left ventricle (LV), left atrium (LA), and aortic arch (AA) were collected at the end of gestation. Expression of MiR-29 and elastin (ELN) mRNA were quantified. RESULTS: LA miR-29 (a, c) expression was highest in PnOb. In the LV, miR-29b expression trended lower (P=.059) for PnOb animals. ELN mRNA expression correlated positively with miR-29b expression in AA (r=.76, P=.03). CONCLUSION: Maternal obesity diminishes miR-29 adaptation to pregnancy. Pharmacologic, tissue-specific targeting of miRNA-29 may represent a strategy for prevention and treatment of MO complications.

Comparison of ProTaper Next and HyFlex instruments on apical debris extrusion in curved canals.

AIM: To evaluate the amount of apically extruded debris after root canal instrumentation with ProTaper Next and HyFlex instruments in curved root canals. METHODOLOGY: Forty extracted mandibular first molar teeth with curved mesial roots and of similar lengths were instrumented using ProTaper Next or HyFlex instruments. The extruded debris was collected into pre-weighed Eppendorf tubes. The tubes were stored in an incubator at 68 °C for 5 days. The tubes were weighed to obtain the final dry weight of the extruded debris. The weight of the extruded debris was determined by subtracting the initial weight from the final weight. Distribution of data was determined by Shapiro-Wilk test. Continuous variables were compared with the Independent Sample t-test or Mann-Whitney U-test. The significance level was set at P = 0.05. RESULTS: Both instruments were associated with apical debris extrusion. The HyFlex group had significantly less debris extrusion than the ProTaper Next group (P = 0.014). CONCLUSION: HyFlex CM was associated with significantly less apical extrusion than ProTaper Next.

Reproductive performance after hysteroscopic metroplasty in infertile women: complete versus partial uterine septum.

OBJECTIVE: To investigate the impact of hysteroscopic metroplasty on pregnancy outcome in women with complete or incomplete uterine septum (US) accompanying infertility. MATERIALS AND METHODS: Seventy-three patients who had hysteroscopic metroplasty for complete and incomplete US with primary and secondary infertility were reviewed. Obstetric outcomes (number of pregnancies, live births, and miscarriages) up to 36 months follow up period were investigated. RESULTS: Twenty-five patients in complete US and 28 patients in incomplete US became pregnant in 36 months follow up. Postoperative miscarriage rate was significantly lower in patients with complete US (p = 0.0001,p = 0.0001, respectively). The mean gestational week at the time of birth and mean birth weight of the in- fants were significantly lower in patients with complete US compared to the incomplete US cases (p = 0.026, p = 0.049, respectively). Postoperative pregnancy rate was significantly lower in incomplete US patients with primary infertility compared with secondary in- fertility (p = 0.037). CONCLUSION: Hysteroscopic metroplasty improves fertility and pregnancy performance. This improvement is more prominent in patients with complete US, and incomplete US patients with secondary infertility.

Apical extrusion of debris using ProTaper Universal and ProTaper Next rotary systems.

AIM: To assess and compare the amount of extruded debris after canal preparation using ProTaper Universal and ProTaper Next files. METHODOLOGY: Forty extracted mandibular premolars with single canals and of similar lengths were instrumented using the ProTaper Universal F3 or the ProTaper Next X3. The extruded debris during instrumentation was collected into pre-weighed Eppendorf tubes. The tubes were stored in an incubator for 5 days. The tubes were weighed to obtain the final dry weight of the extruded debris. The amount of apically extruded debris was calculated by subtracting the initial weight of the tube from the final weight. The distribution of the data was examined using the Shapiro-Wilks test. Continuous variables were compared with an independent-samples t-test for two groups. RESULTS: All specimens were associated with apical debris extrusion. The ProTaper Universal group produced a significantly greater amount of debris extrusion (P < 0.001). The lowest and highest amounts of debris for PTU and PTN groups were recorded as 0.00117-0.00165 g and 0.00017-0.00067 g, respectively. CONCLUSION: ProTaper Next files was associated with significantly less extruded apical debris when compared to ProTaper Universal files.

Genetic bottlenecks in Turkish okra germplasm and utility of iPBS retrotransposon markers for genetic diversity assessment.

Lack of requisite genetic variation in Turkish okra has necessitated the use of different types of markers for estimating the genetic diversity and identifying the source of variation. Transposable elements, present abundantly in plant genomes, generate genomic diversity through their replication and are thus an excellent source of molecular markers. We hypothesized that inter-primer binding site (iPBS)-retrotransposons could be the source of variation because of their genome plasticity nature. In the present study, genetic diversity of 66 okra landraces was analyzed using iPBS-retrotransposon markers. iPBS-retrotransposons detected 88 bands with 40.2% polymorphism and an average of 6.8 bands per primer. Gene diversity and Shannon's information index ranged from 0.01 to 0.13 and 0.02 to 0.21 for iPBS-retrotransposons and from 0.06 to 0.46 and 0.14 to 0.65 for simple sequence repeat (SSR) markers, respectively. Polymorphism information content value for retrotransposons varied between 0.12 and 0.99, while that for SSR was from 0.52 to 0.81. Neighbor joining analysis based on retrotransposons and SSRs divided all the accessions into four clusters; however, SSR markers were more efficient in clustering the landraces based on their origin. Using the STRUCTURE software for determining population structure, and two populations (at the number of hypothetical subpopulations, K = 2) were identified among the landraces. Low genetic diversity in Turkish okra highlights the need for the introduction of plants from countries with greater genetic diversity for these crops. This study also demonstrates the utility and role of iPBS-retrotransposons, a dominant and ubiquitous part of eukaryotic genomes, for diversity studies in okra.

Comparison of hardness of three temporary filling materials cured by two light-curing devices.

AIM: Polymerization ability of light-curing devices can affect the light-cured material hardness. The purpose of the present study was to evaluate and compare the hardness of three temporary filling materials that had been light-cured by either a light emitting diode (LED) or a halogen light-curing unit. METHODS: The temporary filling materials, First Fill, Voco Clip and Bioplic, were placed in wells in a Teflon plate. The 24 specimens of each material were divided into two groups (N.=12/group) for photo-activation by either of the two light-curing units. The LED or halogen device was applied for 40s to the top surface of each specimen. A Knoop hardness test was performed on the top and bottom surface of each specimen, with five measurements per specimen. RESULTS: The highest hardness values for both the LED and halogen treated groups were observed for First Fill and the lowest values were for Voco Clip in top and bottom surfaces. The hardness obtained for the three materials with the halogen unit were significantly higher than the values obtained with the LED unit in both surfaces (P<0.05). CONCLUSION: First Fill light-cured temporary material exhibited the highest hardness values on the top and bottom surfaces than Voco Clip and Bioplic temporary materials. The hardness of light-cured temporary filling materials can be affected by the type of light-curing unit.

An in vitro comparison of working length determination by two motor-driven electronic apex locators.

AIM: The aim of this study was to evaluate the in vitro working length determination of two different apex locator integrated endodontic motors during mechanical preparation. METHODS: A total of 51 maxillary incisors were selected. The access cavities were prepared. The actual working lengths (AWL) were predetermined with a #15 stainless steel file. Specimens were then mounted in an alginate model. RESULTS: Working lengths recorded were VDW Gold (V1), Tri Auto ZX (T1) without using electronic motor and VDW Gold (V2), Tri Auto ZX (T2) by using apex locators in electronic motor operation mode. Data was analyzed by repeated measurements of ANOVA (α=0.01). No difference was found between V1, V2, T1 and T2 (P>0.01). However, statistical analysis found significant differences between AWL and other groups (P<0.01). CONCLUSION: As the values obtained in motor driven mode are equivalent to manual mode measurements, both devices can be safely used without disruption of working length.

Elective bladder preservation with multimodality treatment for bladder cancer.

PURPOSE: To observe the outcome of maximal transurethral resection of bladder tumor (TURBT) followed by induction chemotherapy and concurrent chemoradiotherapy in medically inoperable patients with bladder cancer. METHODS: This study included 30 patients with stage T 2-4 bladder cancer. The patients were first treated with TURBT, and then received 2 cycles of induction chemotherapy with gemcitabine and cisplatin, followed by concurrent chemoradiotherapy with gemcitabine. RESULTS: Median follow up was 28.9 months. Radiologically, complete and partial response rates were 60 and 36.7%, while cystoscopically they were 40 and 30%, respectively. Local progression (4 cases) and distant metastasis (11 cases) were noted. Median overall survival and progressionfree survival were 32 and 21 months, respectively. One -and 2-year overall survival and progression-free survival rates were 97.60% and 83.49%, respectively. CONCLUSION: The multimodal treatment performed in this study was well tolerated and achieved a high rate of bladder preservation in selected patients with bladder cancer.

The frequency of sodium hypochlorite extrusion during root canal treatment: an observational clinical study.

BACKGROUND: To determine the frequency of sodium hypochlorite (NaOCl) extrusion and evaluate the outcome of the injury. METHODS: A total of 1123 teeth indicated root canal treatment were included. An open-ended needle was used during/after the instrumentation. Acute burning pain during irrigation was considered as NaOCl extrusion. Negative aspiration was applied for patients with extrusion, and appropriate treatment was planned due to the symptoms. The number of patients who experienced extrusion and symptoms were recorded. Analysis of variance (ANOVA), at P < 0.05, was used to compare the data groups. RESULTS: NaOCl extrusion rate was found at 0.89%, and the injury with swelling that differential diagnosis of NaOCl accident caused by extrusion rate was 0.18%. The most common findings besides acute pain, as a sign of extrusion (n = 10), were accompanying apical bleeding (n = 6) and swelling (n = 2). According to the number of visits, a significant correlation was found between the symptoms (P = 0.010). No serious injury such as a neurological sign, tissue necrosis or trismus occurred in any patient. CONCLUSIONS: Demographic characteristics of the patients and preoperative condition of teeth were not related to NaOCl extrusion. The increasing number of visits may affect the probability of an accident. Negative aspiration immediately may be crucial in preventing severe injuries.

Factors affecting pregnancy outcome of intrauterine insemination cycles in couples with favourable female characteristics.

The aim of the presented study is to determine the effect of different sperm parameters on the pregnancy rate of intrauterine insemination (IUI) cycles in women with favourable fertility characteristics treated for infertility. Medical records of 212 infertile couples who had undergone a total of 253 cycles were reviewed retrospectively. Inclusion criteria for women were age <35 years, antral follicle count >5, FSH <15 IU/ml, and at least one patent tube documented by HSG or laparoscopy. Clinical pregnancy rates were achieved as 15.8% per cycle, and 18.8% per couple. Woman's age, partner's age, total number of motile sperm (TMS) and motility, significantly influenced pregnancy rate. Pregnancy rate was the highest when women were aged <25 and TMS >10 × 10(6). Partner's age significantly affected the pregnancy rate per cycle in women aged <30 years and TMS >10 × 10(6). Woman's age (OR: 5.4 95% CI: 1.2-24.3) and TMS (OR: 0.06 95% CI: 0.003-0.89) were predictor variables as regards to pregnancy. Pregnancy rate was the highest in IUI cycles when woman was <25 years old, TMS was >10 × 10(6), and morphology was >4%. Male age was found to be another determining factor for IUI success, even if they had a normal spermiogram.

Evaluation of residual antimicrobial effects and surface changes of gutta-percha disinfected with different solutions.

AIM: To determine the possible residual antibacterial effects and possible surface changes caused by 5.25% NaOCl, 2.5% NaOCl, 2% CHX and 0.05% Octenisept on in vitro gutta-percha points after different disinfection protocols. MATERIALS AND METHODS: A total of 121 standard # 40, 0.2% gutta-percha cones were cut 10 mm from the tip, sterilized with ethylene oxide. The samples were divided into five groups, and each group was divided into three subgroups according to immersion periods of gutta-percha cones into solutions. One gutta-percha cone from each group was selected for SEM evaluation. RESULTS: All of the tested solutions were effective on the selected microorganisms when compared with the control solution. No surface alterations were detected on the gutta-percha cones. CONCLUSION: In the limits of this study, immersion of gutta-percha into 2% CHX for one minute was found the most effective method to eliminate the selected microorganisms. CLINICAL SIGNIFICANCE: Although gutta-percha points are aseptic in their package, once opened and used, gutta-percha cones may be contaminated. In order to eliminate bacteria and not to cause surface changes on gutta-percha cones, disinfection solution must be selected carefully.

Analysis of posterior circulation diameters depending on age, sex and side by computed tomography angiography.

BACKGROUND: Posterior circulation of brain is important because of vital organs' blood supply provided by them. In this study, we evaluate the relationship of posterior circulation measurements with age, gender and side by using computed tomography angiography (CTA) images. MATERIALS AND METHODS: A total 199 brain CTA examinations were retrospectively analysed for all posterior circulation arteries (vertebral artery, basilar artery, posterior cerebral artery [PCA], superior cerebellar artery [SCA], anterior inferior cerebellar artery, and posterior inferior cerebellar artery [PICA]) to compare the difference based on age, gender and side. RESULTS: There is no correlation between age and the mean diameters of all vessels (p > 0.05). The mean diameter of left vertebral artery was higher than right vertebral artery in all genders (p = 0.004 for males and p < 0.001 for females). The mean diameter of left SCA and PICA were higher than right SCA and PICA in females (p = 0.032 and p = 0.027, respectively). The mean diameters of basilar, left PCA, left SCA, left vertebral, right PCA, right SCA, right PICA and right vertebral artery were higher in males and that differences were statistically significant (p < 0.001, p = 0.002, p = 0.006, p = 0.004, p = 0.001, p = 0.003, p = 0.002, and p = 0.006, respectively). CONCLUSIONS: The posterior circulation vessel diameter is not affected by aging. The mean diameters of basilar artery, both PCAs, both SCAs, right PICA, both vertebral arteries were higher in males. The mean diameter of left vertebral artery is higher than that of right vertebral artery in all genders.

Dyskeratosis congenita: clinical report and review of the literature.

Dyskeratosis congenita (DKC) is an inherited disorder that usually presents in males, consisting of the triad of leukoplakia of the mucous membranes, nails dystrophy and skin pigmentation. Oral and dental abnormalities may also be present. Most cases are X-linked autosomal dominant, but recessive forms have also been reported. This study describes herein a case in which the classic triad of signs was present, along with the development of leukoplakia in the buccal mucosa. Our patient, a 25-year-old man, presented with several characteristic systemic features of this condition, together with the following oral features: hypodontia, delayed dental eruption, short blunt roots, extensive caries, gingival inflammation and bleeding, loss of alveolar bone and buccal mucosa with leukoplakia and irregular ulcers. The patient was given full preventive care. The primary teeth were extracted under local anaesthesia. After establishing optimal oral health, oral hygiene instructions were given to the patient and he was rehabilitated with fixed and removable partial denture. Prosthetic treatments were carried out after establishing optimal oral health. This treatment option appears beneficial in this patient, resulting in rehabilitation of occlusion and less mechanical irritation to the oral mucosa.
