Usporedba učinkovitosti fleksibilne laringealne maske i endotrahealne intubacije kod adenotonzilektomije

This study compared the effectiveness of flexible laryngeal mask (F-LMA) insertion and endotracheal intubation in pediatric patients undergoing adenotonsillectomy surgery. A total of 60 patients aged 2-12 years were included in the study. Patients were divided into the F-LMA group (n=30) and endotracheal tube (ETT) group (n=30). The groups were compared according to intubation time, heart rate, SpO2, EtCO2, airway pressure, surgical field of view, and recovery time. Both the insertion time and recovery time were shorter in the F-LMA group than in the ETT group (16.93±4.84 s vs. 23.93±8.74 s; and 10±2 min vs. 14.5±3 min; p<0.001 both). The airway pressure measurements at 5-min intervals were significantly lower in the F-LMA group than in the ETT group (p<0.001). F-LMA may be a useful alternative to ETT for adenotonsillectomy surgery because it is safe, provides shorter induction and recovery times, reduces intraoperative airway pressure, and provides an adequate operative field of view.U ovom istraživanju usporedili smo učinkovitost postavljanja fleksibilne laringealne maske (F-LMA) i endotrahealne intubacije (ETT) u pedijatrijskih bolesnika podvrgnutih adenotonzilektomiji. U studiju je bilo uključeno ukupno 60 bolesnika u dobi od 2-12 godina. Bolesnici su podijeljeni u dvije skupine, F-LMA i ETT, od po 30 bolesnika. Ove dvije skupine uspoređene su prema sljedećim parametrima: trajanje intubacije, srčani ritam, SpO2, EtCO2, tlak dišnih putova, kirurško vidno polje i vrijeme oporavka. Vrijeme postavljanja kao i vrijeme oporavka bili su kraći u skupini F-LMA nego u skupini ETT (16,93±4,84 s prema 23,93±8,74 s, p=0,001; 10±2 min prema 14,5±3 min, p<0,001). Tlak dišnih putova mjeren u 5-minutnim razmacima bio je značajno niži u skupini F-LMA u usporedbi sa skupinom ETT (p<0,001). F-LMA mogla bi biti korisna alternativa za ETT kod adenotonzilektomije, jer je sigurna, omogućava kraće vrijeme indukcije i oporavka, snižava intraoperacijski tlak u dišnim putovima te osigurava odgovarajuće operativno vidno polje

Investigation of Serum Uric Acid Levels in Individuals Eating Different Diets

Background: Reducing uric acid (UA) levels can provide some improvements in terms of the development risk and course of various diseases. Early diagnosis and treatment of UA elevation have become an important research area in recent years. Objectives: The present study aimed to investigate the relationship between diets and the change in serum UA levels after diets with different carbohydrate, and fat ratios were applied in male and female patients with or without high serum UA levels. Methods: In the study, three different diets were applied, including a low-carbohydrate diet, a low-fat diet, and a diet low in both carbohydrates and fat. The research was performed with a total of 41 patients (10 males and 31 females) who were referred to the diet polyclinic. Diet programs containing different carbohydrate and fat ratios were applied to the patients. The UA parameters of the participants were evaluated retrospectively. Afterward, pre-diet and post-diet serum UA levels were measured, and the results were compared statistically. Results: Following diet programs, there was a significant decrease in both serum UA levels and weight loss in patients. No significant difference was found between the diets applied in terms of reducing serum UA levels. Further, no significant correlation was observed between serum UA levels and diet duration. However, in the correlation graph, there was a more pronounced reduction trend in serum UA levels with an increase in the diet period. No significant correlation was found between weight values and duration of diet. Finally, the difference between UA levels and weight changes was statistically significant (P<0.001). Conclusion: In addition to examinations for various diseases, adding UA levels to the test panel in routine biochemistry screenings and evaluating the results together with clinical findings and taking necessary precautions in a timely manner are of critical importance for public health

Social Appearance Anxiety in Adult Patients with Acne: A Cross-Sectional Study

The severity of acne may not directly reflect the psychological state of a patient. The aim of the present study was to evaluate the social appearance anxiety with overall morbidity in patients with acne. One hundred adult patients with acne and 67 age and sex-matched healthy controls were enrolled in the study. The patients and controls were asked to complete the Social Appearance Anxiety Scale (SAAS) and the General Health Questionnaire-12 (GHQ-12). Acne severity was evaluated objectively by the Global Acne Grading System (GAGS) and subjectively by the Visual Analogue Scale (VAS).  The mean score on SAAS (37.69±13.53; mean ± Standard deviation) was significantly higher than in the control group (32.48±9.34) (p=0.05). No significant difference was observed between the GHQ-12 scores of the acne (2.19±2.64) and the control group (1.63±2.2) (p=0.152). There was no correlation between the GAGS and the VAS (p=0.417). The SAAS scores of the patients with acne were correlated with the GAGS scores (p=0.05) but not correlated with VAS (p=0.481). The GHQ-12 scores were not correlated with GAGS (p=0.96) or with VAS (p=507). No statistical correlation was established between sex and the GAGS scores (p=0.385), SAAS scores (p=0.611), and GHQ-12 scores (p=0.196). The duration of acne was not correlated with SAAS scores (p=0.814) or with GHQ-12 scores (p=0.24). Social appearance anxiety is significant in adult patients with acne and it is correlated with objective acne severity. However, acne does not seem to be associated with substantial psychological distress or formal psychiatric disorder in adults.   </p

The Prevalence of Antinuclear Antibodies in Patients with Sarcoidosis

Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases. Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients. Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method. Results. Average age of the 42 patients (10 males) with sarcoidosis was 45.2 (20–70 years), and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5%) patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients), in 19 of RA patients (42.2%), and in two of healthy volunteers in low titer (P<0.001). In the subgroup analysis made by immunblot test, one patient had anticentromere antibody, one had anti-Ro antibody, one had anti-Scl-70 antibody, one had anti-dsDNA antibody, and eight patients were negative. The two patients who had anticentromere and anti-Scl-70 antibodies had also Sjögren’s syndrome and scleroderma diagnosis, respectively. Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject

A multiparametric approach to cerium oxide nanoparticle toxicity assessment in non‐biting midges

Cerium oxide nanoparticles (nano-CeO2) are included in the OECD priority list of engineered nanomaterials for the assessment of their environmental impact. The present study was carried out in order to assess the nano-CeO2 toxicity to freshwater midge Chironomus riparius larvae at concentrations of 2.5, 25, 250 and 2500 mg of nano-CeO2 per kg of sediment. Experiments were designed to assess the prolonged exposure of midges to nano-CeO2 while adhering to OECD guideline number 218. The following parameters were investigated: nano-CeO2 uptake by the larvae, oxidative stress parameters, the in vivo genotoxic effect and life trait parameters. ICP-MS analysis showed a significant positive correlation between the concentration of nano-CeO2 in the sediment and its uptake by the larvae. No significant mortality was observed in C. riparius and oxidative stress was not detected. The only significantly induced sublethal effect was genotoxicity, which began to manifest at a LOEC concentration of 25 mg kg-1 of sediment and progressively increased at higher concentrations. Therefore, this study indicates that exposure to nano-CeO2 contaminated freshwater sediments does not pose a risk to chironomids at environmentally realistic concentrations. However, significant accumulation of nano-CeO2 by chironomid larvae may pose a risk through trophic transfer to organisms further up in the food chain

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
