RESUMO

OBJECTIVE: Cancer patients are among the high-risk groups where COVID-19 infection tends to be severe and can lead to increased mortality. Therefore, they are included in the priority groups for COVID-19 vaccination. This study aimed to compare the levels of SARS-CoV-2 immunoglobulin G (IgG) antibodies following two different COVID-19 vaccinations between hematology-oncology patients and healthcare personnel and to identify factors associated with these antibody levels. PATIENTS AND METHODS: A prospective study was conducted with 91 hematology-oncology patients (cancer group) and 75 healthcare personnel (control group) from January 2020 to June 2023. The cancer and control groups comprised adults who had received a booster dose, with either a single dose of BNT162b2 or two doses of CoronaVac™ spaced one month apart, following their primary vaccination with two doses of either CoronaVac™ or BNT162b2. Four weeks after the administration of the booster dose, levels of SARS-CoV-2 IgG antibodies were assessed using an ELISA kit. Antibody levels above 50 AU/mL were accepted as signifying seropositivity. RESULTS: The median SARS-CoV-2 IgG antibody level was lower in the cancer group compared to the control group (4,509 vs. 7,268, p = 0.004), while the rate of seroconversion was similar between the groups (97.8% vs. 100%, p = 0.564). In the cancer group, no association was found between SARS-CoV-2 IgG antibody levels and age, sex, comorbidity, type of malignancy, stage and duration, or type of vaccine. CONCLUSIONS: In cancer patients, the seroconversion positivity rate was about 98%. However, antibody responses were still lower compared to the control group. No difference was detected in antibody levels among cancer patients based on the type of vaccine.

RESUMO

BACKGROUND: Severely calcified coronary lesions present a particular challenge for percutaneous coronary intervention. AIMS: The aim of this randomized study was to determine whether coronary intravascular lithotripsy (IVL) is non-inferior to rotational atherectomy (RA) regarding minimal stent area (MSA). METHODS: The randomized, prospective non-inferiority ROTA.shock trial enrolled 70 patients between July 2019 and November 2021. Patients were randomly (1:1) assigned to undergo either IVL or RA before percutaneous coronary intervention of severely calcified coronary lesions. Optical coherence tomography was performed at the end of the procedure for primary endpoint analysis. RESULTS: The primary endpoint MSA was lower but non-inferior after IVL (mean: 6.10 mm2 , 95% confidence interval [95% CI]: 5.32-6.87 mm2 ) versus RA (6.60 mm2 , 95% CI: 5.66-7.54 mm2 ; difference in MSA: -0.50 mm2 , 95% CI: -1.52-0.52 mm2 ; non-inferiority margin: -1.60 mm2 ). Stent expansion was similar (RA: 0.83 ± 0.10 vs. IVL: 0.82 ± 0.11; p = 0.79). There were no significant differences regarding contrast media consumption (RA: 183.1 ± 68.8 vs. IVL: 163.3 ± 55.0 mL; p = 0.47), radiation dose (RA: 7269 ± 11288 vs. IVL: 5010 ± 4140 cGy cm2 ; p = 0.68), and procedure time (RA: 79.5 ± 34.5 vs. IVL: 66.0 ± 19.4 min; p = 0.18). CONCLUSION: IVL is non-inferior regarding MSA and results in a similar stent expansion in a random comparison with RA. Procedure time, contrast volume, and dose-area product do not differ significantly.

RESUMO

AIM: To investigate the changes in the biomarker levels related to inflammation and tissue destruction in the periapical exudate of mandibular pre-molar teeth with asymptomatic apical periodontitis after receiving intracanal cryotherapy, to compare cryotherapy and control groups in terms of analgesic intake, interappointment, and post-operative pain and evaluate the correlation between biomarker levels and interappointment pain. METHODOLOGY: Mandibular pre-molar teeth of 44 patients aged 18-35 years, diagnosed with asymptomatic apical periodontitis, were root canal treated in two visits (registered as NCT04798144). Baseline periapical exudate samples were obtained, and the patients were assigned to either control or intracanal cryotherapy group according to the final irrigation with distilled water either at room temperature or 2.5°C. The canals were dressed with calcium hydroxide. In the second visit, the calcium hydroxide was removed with passive ultrasonic irrigation, and the periapical exudate was sampled again. IL-1ß, IL-2, IL-6, IL-8, TNF-α, PGE2 and MMP-8 levels were determined with ELISA. Post-operative pain levels were recorded for 6 days following both visits using a visual analogue scale. Data were analysed using t-test, the Mann-Whitney U test and correlation tests. RESULTS: There was a significant correlation between the pain scores reported after first visit and IL-1ß and PGE2 levels (p < .05). IL-1ß, IL-2 and IL-6 levels showed no significant difference in the cryotherapy group (p > .05), while they significantly increased in the control group (p < .05). There was a decrease in IL-8, TNF-α, PGE2 and MMP-8 levels, however, the difference was not significant (p > .05). Pain scores were significantly lower in the cryotherapy group for the first 3 days (p < .05), except for 24th hours (p > .05). CONCLUSIONS: The positive correlation between interappointment pain and IL-1ß and PGE2 levels might indicate that these biomarker levels can be used to predict the severity of post-operative pain. Intracanal cryotherapy was effective in reducing post-operative pain in the short term in teeth with asymptomatic apical periodontitis. Cryotherapy prevented an increase in IL-1ß, IL-2 and IL-6 levels compared with the control group.

RESUMO

OBJECTIVE: Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups. PATIENTS AND METHODS: The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants. RESULTS: When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded. CONCLUSIONS: Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also, these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However, further studies in other ethnic groups are needed to confirm these results.

RESUMO

OBJECTIVE: Gestational diabetes mellitus (GDM) is a type of diabetes that affects from 3.8% to 6.9% of pregnancies worldwide, causing significant mortality and unfavorable obstetric outcomes, such as delivery trauma and macrosomia risk. The fundamental processes of this metabolic disorder that first appeared during pregnancy are still unknown. Tissue hormones, particularly adipokines, have aided in understanding the pathophysiology of numerous disorders in recent years. This study aims to determine if Apelin-13 (APLN-13), Apelin-36 (APLN-36), Elabela (ELA), and nitric oxide (NO) molecules have all a part in the pathophysiology of GDM. PATIENTS AND METHODS: The study included 30 pregnant control women and 30 pregnant women who had been diagnosed with GDM in the second trimester and whose body mass index and age were compatible with each other. Blood samples were collected from 60 participants during the second trimester (30 control pregnant women and 30 GDM pregnant women) and postpartum (17 controls vs. 14 GDM). In these blood samples, the amounts of APLN-13, APLN-36, ELA, and NO were studied using the ELISA method. In addition, the participants' glucose, lipid profiles, and other parameters were obtained from the hospital record files. At postpartum, 29 pregnant women (13 control and 16 pregnant women with GDM) dropped out of the study without explanation. RESULTS: In the second trimester and postpartum plasma of mothers with GDM, APLN-13, APLN-36, NO, and ELA molecules were found to be significantly higher (< 0.05), compared to those of the control mothers, while APLN-13, APLN-36, NO values were significantly lower (0.05). While APLN-13, APLN-36, NO amounts in mothers with GDM were positively correlated with glucose amounts, they were negatively correlated with ELA amounts. Similarly, the triglyceride amounts in mothers with GDM were positively correlated with APLN-13, APLN-36 and NO, while they were negatively correlated with the ELA amounts. Due to gestational diabetes, APLN-13, APLN-36, NO, glucose, and triglyceride increased, and ELA decreased. CONCLUSIONS: It is predicted that the glucose increase in GDM is because Apelins reduce glucose transport to erythrocytes by inhibiting the sodium-dependent glucose transporter (SGLT) and that the increase in triglyceride and NO may be associated with high glucose levels in GDM. As a result, we believe that the above-mentioned chemicals may cause GDM Pathology by triggering one another.

RESUMO

OBJECTIVE: Metabolic syndrome (MetS) and obesity are important public health problems associated with adipose tissue mass. Asprosin, visfatin, and subfatin are new members of which fate in MetS and obesity has not been fully revealed yet. Thus, this study was to investigate the association between asprosin, visfatin, subfatin, and biochemical values, demographic data, and body composition measurement values in MetS patients with and without obesity. PATIENTS AND METHODS: Blood samples were taken from a total of 90 people, including 31 MetS patients with obesity, 29 MetS patients without obesity, and 30 healthy (control). Asprosin, visfatin, and subfatin were studied by the ELISA method. RESULTS: There was a negative correlation between asprosin and Body Mass Index (BMI) in the MetS + Obese group. The correlations between asprosin and urea and fasting insulin (FI) levels in the MetS group were positive and statistically significant (p < 0.05). While there was a statistically significant negative correlation (p < 0.05) between visfatin and BMI in the MetS + Obese group, the correlation with waist circumference in the MetS + Obese and MetS groups was statistically significant and negative (p < 0.05). There was a statistically significant negative relationship (p < 0.05) between aspartate aminotransferase value and visfatin. The results between visfatin values and asprosin and subfatin in all groups were significant (p < 0.05). CONCLUSIONS: There is a direct relationship between circulating amounts of asprosin, visfatin, and subfatin hormones and age, weight, height, diastolic blood pressure, high-density lipoprotein-cholesterol, aspartate aminotransferase, alanine transaminase, and creatinine. Therefore, asprosin, visfatin, and subfatin hormones are the new biomarkers of metabolic turbulence.

RESUMO

Despite significant advances in medicine, mortality due to cardiovascular disease is not yet preventable. We investigated the amounts of elabela (ELA) and apelin, synthesized by cardiomyocytes, and changes of these compounds in cardiac tissue and circulation after administration of iloprost (ILO) and sildenafil (SIL) in rats with induced myocardial ischemia (MI). We also investigated a connection with circulating troponin-I, creatine kinase (CK), creatine kinase-myocardial band (CK-MB) and nitric oxide (NO), and total anti-oxidant (TAS)/total oxidant status (TOS). We established eight study groups of five rats each. Group 1, sham, was given only physiologic serum; group 2, ILO; group 3, SIL; group 4, ILO + SIL; group 5, MI; group 6, MI + ILO; group 7, MI + SIL; group 8, MI + ILO + SIL. Troponin-I, CK, CK-MB and TAS-TOS were investigated using an autoanalyzer. NO, ELA and apelin were analyzed by ELISA. Tissue apelin and ELA expressions and localizations were determined by immunohistochemistry. The MI group compared to the control (sham) group showed that ELA, apelin, troponin-I, CK, CK-MB, NO and TOS levels were elevated significantly. Concentrations of these factors increased in MI, but decreased after ILO and SIL administration. The largest decrease of TOS was identified in the ILO + SIL group. ELA and apelin may be novel indicators of MI and administration of ILO and SIL, individually or together, may be useful for treating MI.

RESUMO

The actual role of splint therapy in preventing excessive loading of the temporomandibular joint (TMJ) is still debated. Lower intra-articular pressure levels have been measured in patients wearing occlusal splints, which may also reduce oxidative stress in the articular spaces. The aim of this study was to determine whether splint therapy reduces oxidative stress and inflammation in TMJ internal derangement patients by measuring interleukin 6 (IL-6), malondialdehyde (MDA), and 8-hydroxydeoxyguanosine (8-OHdG) levels in the synovial fluid (SF). Twenty-four patients with a temporomandibular disorder (TMD) were included in the study. TMJ SF samples were obtained prior to arthrocentesis. Twelve patients used a 2-mm hard acrylic, maxillary stabilization-type splint for 3 months after arthrocentesis. Twelve patients had no treatment after the SF aspiration. Second SF samples were obtained from all patients at 3 months post arthrocentesis. IL-6, MDA, and 8-OHdG levels in the samples were evaluated. All patients showed a significant symptomatic improvement after treatment (P < 0.005). No statistical correlation was found between the two groups concerning pre-treatment and 3-month SF levels of MDA, 8-OHdG, and IL-6. Although splint therapy was found to be successful in eliminating clinical symptoms of TMD, the results showed no beneficial effect on inflammation and oxidative stress markers in the synovial fluid.

RESUMO

Central nervous system (CNS) metastasis is a rare event in the course of late stage epithelial ovarian cancer (EOC); however its incidence is increasing in parallel with prolonged survival of patients. OBJECTIVE: The authors assessed the clinical parameters and potential prognostic features in patients with CNS metastatic disease. MATERIALS AND METHODS: Clinical data of the 33 patients from the participating centers were retrospectively collected and analyzed. Median age at the time of CNS metastasis was 57 years. Median time from the diagnosis of primary EOC until CNS metastatic disease was 22 months. Nearly half (45.5%) of the patients had single CNS metastatic lesions and all patients in the study group except two received radiotherapy as palliative treatment. Median overall survival (OS) from the time of CNS metastasis was 15 months (0-66). At univariate analysis only number of brain metastatic lesions (p = 0.001) and presence of extracranial disease (p = 0.004) were strongly associated with OS whereas multimodal treatment, size of metastatic lesions, platinum sensitivity, age, grade, and disease stage at presentation were not. Development of CNS metastasis carries a poor prognosis, however patients with single metastatic lesions and only intracranial metastatic disease can have prolonged survival after appropriate palliative management of their disease.

RESUMO

This study was aimed at evaluating the potential effects of acute subdural hematoma (ASDH) and diclofenac sodium (DS) therapy following ASDH on the rat hippocampus. Twenty-four male Sprague Dawley rats were used and divided into four groups. 0.1 ml of non-heparinized autologous blood from the tail vein of the animals in the non-treatment group (NTG) and treatment group (TG) was injected into the subdural space. The TG received intramuscular diclofenac sodium at a 15 mg/kg dose daily from the postoperative second hour to the seventh day after the operation. The control group (CG) and sham group (SG) were used for control and sham operations, respectively. On the postoperative eighth day, all animals were sacrificed, and the hippocampi of all animals were stereologically and histologically evaluated. Also blood samples of the animals were biochemically analyzed. As a result of the study, the mean number of neurons in CA1, CA2, and CA3 regions of the hippocampus and the total number of neurons were decreased in the hippocampus samples of the NTG and especially the TG subjects. When comparing the second blood samples, there was no difference between the levels of adrenaline and serotonin among the groups. However, after the operation, noradrenalin levels in the treatment group were found to be higher than those of the sham and control groups (p < 0.05). In the NTG and TG, histopathological findings were observed such as Nissl condensation as well as completely dead and indistinguishable neurons with abnormally shaped, shrunken cytoplasm and nuclei. Also necrotic areas on the specimens of the TG were seen. In immunohistochemical sections, c-FOS positivity was decreased in the NTG and especially the TG. Otherwise, PGC-1 positive cells were increased in the NTG and especially the TG. In this study, it was shown for the first time by means of stereological techniques that using DS after ASDH caused a decrease in the number of hippocampal neurons (CA1, CA2, and CA3 regions).

RESUMO

OBJECTIVE: This study aimed to compare the QT interval changes in women with term pregnancy living at moderately high altitude (1890 m in Erzurum, Turkey) with those of women living at sea level (31 m in Istanbul, Turkey). MATERIALS AND METHODS: One-hundred ten women (n = 55, for each group) with full-term and single child pregnancies. Two different locations in that state were selected: Istanbul, Turkey, which is at 31 m above sea level (Group 1) and Erzurum, Turkey, at 1890 m above sea level (Group 2). Physicians from the two locations participated in the study. We estimated QTc, QTc Max, QTc Min, QT, and QTcd intervals. RESULTS: Moderately high altitude group had significantly longer QT parameters (QTc, QTc Max, QTc Min, QT, and QTcd intervals) compared with sea level group (P < 0.01, for all). CONCLUSIONS: According to our results, QT interval changes occur in term pregnant women living moderately high altitude. These changes may be associated with pregnancy-related cardiovascular complications in moderately high altitude.

RESUMO

AIM: This study aimed to investigate maternal and fetal Doppler flow parameters in term pregnant women diagnosed with fear of childbirth (FOC). MATERIALS AND METHODS: Women between 20 and 40 years with full-term singleton pregnancies (≥37 gestational weeks) were included in the study. All patients were questioned with Turkish form of Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) version A. Women with W-DEQ scores ≥85 were defined as FOC. Forty women diagnosed with FOC (FOC group) and 45 women with W-DEQ scores <85 (control group) underwent Doppler waveform analysis and the pulsatility index (PI) and resistance index (RI) values for uterine, umbilical, and mid cerebral arteries were recorded. RESULTS: Both groups had similar PI and RI values for umbilical and mid cerebral arteries (P > 0.05). However, PI and RI values for both right and left uterine arteries were higher in FOC group than control group (P < 0.05, for right uterine artery PI; P< 0.001, for left uterine artery RI; and P< 0.01, for others). CONCLUSION: It may be suggested that the presence of FOC in term pregnant women seems to have a negative effect on uterine blood flow parameters. When diagnosed with FOC, the women should be referred to a specialist for psychoeducation and psychosomatic support to decrease her fear and to minimize the negative impact of fear on the fetus.

RESUMO

Aeromonas hydrophila is known to be causative agent of an infection named as Bacterial haemorrhagic septicaemia or red pest in freshwater fish. The aim of this study was to develop and validate the glycoprotein-based fish vaccine against Aeromonas hydrophila. For this aim, after identification and characterization of A. hydrophila isolates from fish farms, one A. hydrophila isolate was selected as vaccine strain. Antigenic glycoproteins of this vaccine strain were determined by Western blotting and glycan detection kit. The connection types of these glycoproteins were examined by glycoprotein differentiation kit. Two glycoproteins, molecular weights of 19 and 38 kDa, with SNA connection type were selected for use in vaccination trials. After their purification by SNA-specific lectin and size-exclusion chromatography, protection studies with purified proteins were performed. For challenge trials, four experimental fish groups were designated: Group I (with montanide), Group II (with montanide and ginseng), Group III [with Al(OH)3 ] and Group IV [with Al(OH)3 and ginseng]. The survival ratings of fish were determined, and protection was calculated as 21.56%, 29.41%, 69.83% and 78.88% in groups I, II, III and IV, respectively. In conclusion, A. hydrophila glycoproteins with Al(OH)3 and ginseng could be used as a safe and effective vaccine for fish.

RESUMO

OBJECTIVE: The authors' aim was to develop a logistic regression model based on the ultrasonographic parameters on maternities which are showing a healthy improvement process during the first trimester of pregnancy. MATERIAL AND METHODS: Using 2D transvaginal ultrasound imaging, the crown rump length (CRL), yolk sac (YS), and gestational sac (GS) diameters were recorded in 225 women with gestational age < 11 weeks. Simplified V = 0.523 x length x height x width formula was used for the volume calculations. The results which ended in abortion were not included in the study. RESULTS: Linear regression analyses between yolk sac volume (YSV), YSV = 0.026 + 0.0018 x CRL (r²: 0.15; p < 0.001), gestational sac volume (GSV), GSV= -9.6 + 1.7 x CRL (r²: 0.52; p < 0.001), and embryo volume (EV), EV = -1.64 + 0.18 x CRL (r²: 0.4; p < 0.001), and CRL was made and a linear relationship was detected. The volume measurements showed a meaningful correlation with the week of pregnancy. The space in the GS (GS volume-embryo volume) increased as the age of pregnancy became older (r² = 0.46; p < 0.001). DISCUSSION: The first volume value was made in the first trimester by transvaginal ultrasonography, which showed a correlation with the age of pregnancy.

RESUMO

AIM: We aimed to investigate the effect of colloid infusion immediately before the spinal anesthesia, and the prophylactic intravenous (IV) infusion of ephedrine after injection of intrathecal bupivacaine on hemodynamic parameters, QT, The QT interval corrected for heart rate (QTc), and dispersion of QTc (QTcDisp) intervals in women undergoing the elective cesarean section. MATERIALS AND METHODS: Sixty women scheduled for elective cesarean delivery with spinal anesthesia were allocated randomly to receive either IV fluid preloading with 0.5 L of 6% w/v hydroxyethyl starch solution immediately before the spinal anesthesia (colloid group, n = 30) or prophylactic IV infusion of 15 mg ephedrine (diluted with 10 ml saline, n = 30) over 1-min period after the injection of intrathecal bupivacaine (ephedrine group). Electrocardiography (ECG) tracings were recorded before anesthesia procedure at baseline (T0), 5 min (T1), 10 min (T2), 30 min (T3), 60 min (T4), and 120 min (T5) after the spinal anesthesia. Systolic blood pressure, diastolic blood pressure, mean arterial pressure (MAP), heart rate (HR), and peripheral oxygen saturation (SpO2) values were also recorded at the same time intervals. RESULTS: There were no significant differences between groups with respect to MAP, HR, SpO2, QT, and QTc intervals at any time points (P > 0.05). When compared with the colloid group, the QTcDisp interval at T1was significantly longer in the ephedrine group (P < 0.05). CONCLUSION: Both methods have similar effects on the ECG and hemodynamic parameters during cesarean section. So, both methods may be used in patients undergoing elective cesarean delivery under spinal anesthesia.

RESUMO

PURPOSE OF INVESTIGATION: The authors aimed to research the prevalence of fear of childbirth (FOC) in women with a positive birth experience and some factors associated with FOC. MATERIALS AND METHODS: The study sample consisted of 817 women with positive birth experience within the last month of their pregnancy from February 2012 to May 2013. The data were collected with a questionnaire form including women's demographic-obstetric information and the Turkish form of Wijma Delivery Expectancy Questionnaire. Whether it was a planned pregnancy and their preferable delivery method for the current pregnancy were recorded. RESULTS: The total number of women with FOC was found to be 128 (15.6%). None of the patients had severe FOC. Fear of labour pain was found as the major cause for preferring cesarean section (73.5%). FOC was associated with preferring delivery methods (OR 5.91, 95% CI 3.96-8.84). FOC was associated with pregnancy planning status (OR 2.4, 95% CI 1.66-3.58). CONCLUSION: Fear of childbirth may be seen to some extent in women with a positive birth experience. However even with woman's positive birth experience, it is important to avoid severe FOC. The pregnancy planning status should be evaluated in the early stages of pregnancy and maternal education programs may be offered to reduce FOC level.

RESUMO

Coffin-Lowry syndrome (CLS) is a rare X linked mental retardation syndrome characterised by severe psychomotor and growth retardation, distinct facial phenotype, and progressive skeletal malformations. It is caused by mutations in the RPS6KA3 gene located at Xp22.2. In this report we describe a family with CLS consists of three affected males, and two affected females, arising from c.898C>T mutation in RPS6KA3 gene. A 6 year-old, and a 3 year-old boy both had distinct clinical features of Coffin-Lowry syndrome; severe mental and motor retardation, microcephaly, prominent forehead, hypertelorism, large mouth, large ears, large soft hands, puffy tapered fingers, and pectus carinatum. In addition, they had multiple abnormal brain MRI findings. Other siblings presented with a mild and variable phenotype.

RESUMO

BACKGROUND: Type 2 Diabetes Mellitus is a leading cause of end stage renal disease in the worldwide. Inflammation is regarded as one of the main reasons for the progression of diabetes complications. We aimed to evaluate the association of neutrophil to lymphocyte ratio (NLR) as indicator of systemic inflammation with diabetic retinopathy and nephropathy. PATIENTS AND METHODS: This is a cross-sectional study of 114 prevalent type 2 diabetic subjects. All of the patients underwent detailed examination for the presence of diabetic retinopathy and nephropathy. Diabetic retinopathy was approved and classified according to findings based on flouresceint fundal angiography results. Estimated glomerular filtration rate (eGFR) and microalbumin to creatinine ratio were calculated to establish the diabetic nephropathy. NLR was calculated as ratio of absolute neutrophil count to absolute lymphocyte count. RESULTS: Retinopathy was present in 55 (48.2%) out of 114 patients, whereas nephropathy was present in 62 patients (54.3%). NLR was significantly higher in patients with nephropathy than in patients without nephropathy. NLR was also positively correlated with CRP (p=0.017, r=0.224) and microalbuminuria (p=0.016, r=0.257) whereas negatively correlated with eGFR (p<0.001, r=-0.337) values in the whole cohort. NLR was independent predictors for diabetic nephropathy, whereas it did not appear as an independent associate of diabetic retinopathy. CONCLUSION: NLR and diabetic nephropathy have an independent association between them whereas there was no independent association between NLR with retinopathy in type 2 diabetic patients.

RESUMO

OBJECTIVE: To demonstrate the inhibitory effects of clarithromycin on in vitro tympanosclerosis. METHOD: Twenty-eight rats were divided into three groups: a clarithromycin group, a non-clarithromycin group and a negative control group. Those in the first two groups were injected with Streptococcus pneumoniae following a myringotomy, and tympanosclerosis was experimentally induced. Oral clarithromycin therapy was administered in the clarithromycin group. The other groups received no medical treatment. RESULTS: All eardrums in the clarithromycin and non-clarithromycin groups developed myringosclerosis, but there was only one eardrum, in the clarithromycin group, with very severe myringosclerosis. In the clarithromycin group, 11 ears showed no inflammation and there were no ears with severe inflammation. In the non-clarithromycin group, there were 11 ears with severe inflammation. The mean eardrum thickness in the clarithromycin group was 20.93 µm and in the non-clarithromycin group it was 42.71 µm. CONCLUSION: Acute otitis media and myringotomies induced tympanosclerosis, but clarithromycin reduced the severity of tympanosclerosis.

RESUMO

PURPOSE: Gram-positive anaerobic cocci (GPAC) can be isolated as pathogens from odontogenic infections. Culturing GPAC is time consuming and labor intensive. The objectives of the present study were to examine the utility of polymerase chain reaction (PCR) in directly detecting the presence of GPAC in clinical samples obtained from patients with odontogenic infections and to compare the distribution of GPAC in infected and healthy tissue. MATERIALS AND METHODS: In the present case-control study, the infected tissue from patients and oral mucosal swabs from healthy control subjects were subjected to anaerobic culture and direct PCR analysis for the presence of GPAC. The McNemar, chi-square, and Fisher exact tests and kappa analysis were used for the statistical analyses. P < .05 was regarded as significant. RESULTS: The patient group included 13 men and 14 women, including 9 patients diagnosed with granulation of tooth extraction, 6 with impacted tooth follicles, 4 with peri-implantitis, 3 with abscesses, 2 with epithelial cysts, 2 with infected cysts, and 1 with an oroantral fistula. The control group included 14 men and 12 women. All the patient and control samples contained at least 1 GPAC. The groups did not differ by method of determining GPAC presence, but more microorganisms were detected when clinical samples were directly used for PCR analysis than when cultured bacteria were used (P = .001). CONCLUSIONS: The presence of GPAC in infected tissue cannot be directly related to the development of odontogenic infections. PCR performed directly on clinical material is a sensitive and specific method that can detect GPAC and save time.
