The Promising Effects of Erdosteine and Vitamin B in the Liver Ischemia/Reperfusion Model in Anesthetized Rats.

Background and Objectives: Erdosteine (Erd) is an antioxidant and anti-inflammatory drug. Vitamin B has been reported to exert anti-inflammatory and antioxidant effects. In this study, we investigated the effect of erdosteine and vitamin B complex on a liver ischemia/reperfusion (I/R) model. Materials and Methods: Thirty-two Wistar Albino male rats weighing 350-400 g were used. The animals were randomly selected and divided into four groups. The groups are as follows: first group (Sham), second group (I/R), third group (I/R + vit B), and fourth group (I/R + vit B + Erd). Rats were subjected to 45 min of hepatic ischemia, followed by a 45 min reperfusion period in the I/R and Vitamin B + Erd groups. An amount of 150 mg/kg/day of erdosteine was given orally for 2 days, and 0.05 mL/kg of i.p. vitamin B complex was given 30 min before the reperfusion. Serum biochemical parameters were measured. Serum Total Antioxidant Status (TAS) and Total Oxidant Status (TOS) were measured, and the Oxidative Stress Index (OSI) was calculated. Hepatic tissue samples were taken for the evaluation of histopathological features. Results: In terms of all histopathological parameters, there were significant differences in the I/R + vit B group and I/R + vit B + Erd group compared with the I/R group (p < 0.01). In terms of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), TNF-alpha, and IL-6 levels, there were significant differences between the I/R group and treatment groups (p < 0.01). The lowest TOS and OSI levels were obtained in the treatment groups, and these groups had statistically significantly higher TAS levels compared with the sham and I/R groups (p < 0.01). Conclusions: As a preliminary experimental study, our study suggests that these agents may have potential diagnostic and therapeutic implications for both ischemic conditions and liver-related diseases. These results suggest that the combination of vit B + Erd may be used to protect against the devastating effects of I/R injury. Our study needs to be confirmed by clinical studies with large participation.

Management of kidney injury in critically ill patients with earthquake-induced crush syndrome: A case series of 18 patients.

INTRODUCTION: It was aimed primarily to analyze the development of acute kidney injury (AKI) and treatment management in critically ill patients who developed rhabdomyolysis due to earthquake-related crush syndrome. METHODS: We evaluated 18 patients with crush syndrome who were admitted to the intensive care unit (ICU) after the great earthquake in February 2023 in Turkey. RESULTS: AKI occurred in 83% (n:15) of these patients after ICU admission (AKI-1; 16.6% [n:3], AKI-2; 16.6% [n:3], and AKI-3; 50% [n:9]). While the majority of patients who developed crush syndrome were treated with high volume intravenous hydration, only 33% (n:6) of all patients required renal replacement therapy. All patients who developed AKI had complete recovery in renal functions at the end of 2 months. CONCLUSION: There is no need for routine renal replacement therapy in the treatment of AKI, which is frequently seen in patients with crush syndrome. Most can be treated with high volumes of intravenous fluid.

A Comparison of the Effects of Dexamethasone and Methylprednisolone, Used on Level-3 Intensive Care COVID-19 Patients, on Mortality: A Multi-Center Retrospective Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is often a mild disease, usually manifesting with respiratory complaints, and is sometimes mortal due to multiple organ failure. Hyperinflammation is a known COVID-19 component and is associated with organ dysfunction, disease severity and mortality. Controlling hyperinflammatory response is crucial in determining treatment direction. An important agent in providing this control is corticosteroids. This study aimed to determine whether dexamethasone and methylprednisolone, doses, administration time and duration in COVID-19 treatment are associated with improved treatment outcomes. METHODS: This retrospective multicenter study was conducted with participation of 6 healthcare centers which collected data by retrospectively examining files of 1,340 patients admitted to intensive care unit due to COVID-19 between March 2020 and September 2021, diagnosed with polymerase chain reaction (+) and/or clinically and radiologically. RESULTS: Mortality in the pulse methylprednisolone group was statistically significantly higher than that in the other 3 groups. Mortality was higher in older patients with comorbidities such as hypertension, diabetes mellitus, chronic kidney failure, coronary artery disease, and dementia. Pulse and mini-pulse steroid doses were less effective than standard methylprednisolone and dexamethasone doses, pulse steroid doses being associated with high mortality. Standard-dose methylprednisolone and dexamethasone led to similar effects, but standard dose methylprednisolone was more effective in severe patients who required mechanical ventilation (MV). Infection development was related to steroid treatment duration, not cumulative steroid dose. CONCLUSION: Corticosteroids are shown to be beneficial in critical COVID-19, but the role of early corticosteroids in mild COVID-19 patients remains unclear. The anti-inflammatory effects of corticosteroids may have a positive effect by reducing mortality in severe COVID-19 patients. Although dexamethasone was first used for this purpose, methylprednisolone was found to be as effective at standard doses. Methylprednisolone administered at standard doses was associated with greater PaO2/FiO2 ratios than dexamethasone, especially in the severe group requiring MV. High dose pulse steroid doses are closely associated with mortality and standard methylprednisolone dose is recommended.

The effect of therapeutic plasma exchange therapy on veno-venous ECMO weaning success in severe COVID-19 ARDS patients.

INTRODUCTION: Primarily, this study aimed to investigate the effect of TPE (therapeutic plasma exchange) treatment on successful ECMO weaning in severe COVID-19 ARDS patients treated with V-V ECMO. METHODS: The study was applied retrospectively on patients over the age of 18 who were hospitalized in the ICU between January 1, 2020 and March 1, 2022. RESULTS: The study was performed on 33 patients, 36.3% (n: 12) of whom received TPE treatment. The rate of successful ECMO weaning was statistically higher in the TPE treatment group (without TPE: 14.3% [n: 3], with TPE: 50% [n: 6], p = 0.044). The 1-month mortality was also statistically lower in the TPE treatment group (p = 0.044). In the logistic analysis, It was found that the risk of unsuccessful ECMO weaning increased 6 times in those who did not receive TPE treatment (OR; 6.0, 95% CI; 1.134-31.735, p = 0.035). CONCLUSION: TPE treatment may increase the success rate of V-V ECMO weaning in severe COVID-19 ARDS patients treated with V-V ECMO.

Directed C-H Functionalization of C3-Aldehyde, Ketone, and Acid/Ester-Substituted Free (NH) Indoles with Iodoarenes via a Palladium Catalyst System.

Pd(II)-catalyzed C-H arylations of free (NH) indoles including different carbonyl directing groups on C3-position with aryl iodides are demonstrated. Importantly, the reactions are carried out using the same catalyst system without any additional transient directing group (TDG). In this study, the formyl group as a directing group gave the C4-arylated indoles versus C2-arylation. Using this catalyst system, C-H functionalization of 3-acetylindoles provided domino C4-arylation/3,2-carbonyl migration products. This transformation involves the unusual migration of the acetyl group to the C2-position following C4-arylation in one pot. Meanwhile, migration of the acetyl group could be simply controlled and N-protected 3-acetylindoles afforded C4-arylation products without migration of the acetyl group. Functionalization of indole-3-carboxylic acid (or methyl ester) with aryl iodides using the present Pd(II)-catalyst system resulted in decarboxylation followed by the formation of C2-arylated indoles. Based on the control experiments and the literature, plausible mechanisms are proposed. The synthetic utilities of these acetylindole derivatives have also been demonstrated. Remarkably, C4-arylated acetylindoles have allowed the construction of functionalized pityiacitrin (a natural product).

Functionalization at Nonperipheral Positions of Triazatruxene: Modular Construction of 1,6,11-Triarylated-Triazatruxenes for Potentially Organic Electronics and Optoelectronics.

Functionalization from nonperipheral positions of triazatruxene is representing a challenge. Triarylation of the nonperipheral positions (1, 6, and 11) in triazatruxene scaffold has been achieved for the first time via two approaches. The transformations involve arylation/cyclotrimerization and cyclotrimerization/arylation sequences. POCl3-mediated direct cyclotrimerization of oxindoles containing electron-deficient substituents on the aryl group at the C7-position resulted in the formation of 2-chloroindoles, whereas oxindoles containing electron-donating substituents gave the triazatruxenes. Furthermore, desired triazatruxenes were achieved through cyclotrimerization of 7-bromooxindole followed by coupling with arylboronic acids. NMR structural analysis exhibited that two of the suitably substituted oxindole and triazatuxene may have atropisomerism at room temperature. As a representative triazatruxene scaffold, the optoelectronic properties of 9a have also been studied via ultraviolet-visible (UV-vis) absorption spectra and fluorescence spectra of 9a thin films. Also, density functional theory calculation was realized to get knowledge about frontier molecular orbitals. In the light of the information obtained, an organic light-emitting diode (OLED) device utilizing 9a as an emissive layer was applied to obtain white emission. In brief, this study provides the first examples of the synthesis of triazatruxenes bearing aryl substituents at the nonperipheral positions as candidate compounds for organic electronics, optoelectronics, and material chemistry.

Effect of clival bone growth on the localization of the abducens nerve at the petroclival region: a postmortem anatomical study.

PURPOSE: To investigate the effect of the clival bone pattern on the abducens nerve (AN) localization in the petroclival region between the Pediatric and Adult Groups. METHODS: This study used 12 pediatric and 17 adult heads obtained from the autopsy. The length and width of the clivus and the length of the petrosphenoidal ligaments (PSLs) were measured. The ratio of the length and width of the clivus was accepted as the clival index (CI). The localization of the AN at the petroclival region below the PSL, classified as lateral and medial, were recorded. RESULTS: The average length of the clivus was 26.92 ± 2.88 mm in the Pediatric Group, and 40.66 ± 4.17 mm in the Adult Group (p < 0.001). The average width of the clivus was 22.35 ± 2.88 mm in the Pediatric Group, and 29.96 ± 3.86 mm in the Adult Group (p < 0.001). The average value of the CI was 1.20 in the Pediatric Group and 1.36 in the Adult Group (p = 0.003). The length of the PSL was 7.0 ± 1.47 mm in the Pediatric Group and 11.05 ± 2.95 mm in the Adult Group (p < 0.001). The nerve was located below the medial side of the PSL in the Pediatric Group and below the lateral side in the Adult Group (p = 0.002). CONCLUSIONS: The petrous apex localization of the AN in adults compared with pediatric subjects could be related to the increased growth in the length of the clivus than its width.

Effect of quadratus lumborum block on postoperative analgesic requirements in pediatric patients: a randomized controlled double-blinded study.

BACKGROUND: Quadratus lumborum block (QLB) is a newly-defined trunk block performed with local anesthetic injection by imaging the abdominal muscles with ultrasonography (US) guidance; thus, analgesia is expected to be ensured from the T7-L1 dermatomal segment level. In the study, the aim was making the comparison between the quadratus lumborum block and the intravenous analgesia with tramadol on postoperative analgesic effect in pediatric patients undergoing lower abdominal surgery. METHODS: Patients included in the study were randomly divided into two groups. Cases were assessed as intravenous opioid with 1 mg/kg tramadol HCl (Group O, N.=20) or ultrasonography-guided quadratus lumborum block (Group B, N.=20). Total analgesic amounts in 24 hours and first analgesic requirement times recorded. RESULTS: First analgesic requirement was recorded 3.5 hours later for Group O and eight hours later for Group B, indicating a statistically significant difference (P<0.05). When analgesic consumption in the first 24 hours postoperative is examined, fewer patients in the QLB group required oral paracetamol (P<0.05), therefore lower amounts of oral paracetamol were used (P<0.05). CONCLUSIONS: In conclusion, we believe QLB1 provides effective analgesia in the postoperative period for lower abdominal surgery in pediatric patients.

Description of suicide ideation among older adults and a psychological profile: a cross-sectional study in Turkey.

This study investigates the suicidal ideation and the possible causes for suicidal behaviour in the elderly. Subjects were 150 patients aged 65 and older who were evaluated using the sociodemographic data collection forms, Geriatric Depression Scale (GDS), Suicidal Ideation Scale (SIS), Reasons for Living Inventory (RLI), and Beck Hopelessness Scale (BHS). Of 150 patients, 72.7% were women and 27.3% were men, ages ranged from 65 to 88 years. Suicidal ideation was noted in 30.7% of patients. When the mean of BHS total score between patients with and without suicidal ideation and the mean of BHS subscale's feelings and expectations regarding the future and loss of motivation and hope in terms of subscales were evaluated between the groups with and without suicidal ideation, the scores had a significant difference. When RLI was evaluated in terms of total scores, the suicidal ideation mean score was 243.74 ± 32.28, while the non-suicidal ideation mean score was 267.27 ± 24.36. There was a significant relationship between the two groups. We found low level of education, low level of reasons for living and higher psychiatric morbidity (generalized anxiety disorder and comorbid depressive disorder) in with suicidal ideation in the elderly.

Resumo Este estudo tem por objetivo investigar os fatores que levam à ideação suicida e às possíveis causas para o comportamento suicida em idosos. Foram estudados 150 pacientes com idade igual ou superior a 65 anos, que foram avaliados utilizando os formulários de coleta de dados sociodemográficos, Escala de Depressão Geriátrica (EDG), Escala de Ideação Suicida (EIS), Inventário de Razões para Viver (IRV) e Escala de Desesperança de Beck (EDB). De 150 pacientes, 72,7% eram mulheres e 27,3% homens , com idades de 65 a 88 anos. A ideação suicida foi observada em 30,7% dos pacientes . Ao se avaliar a média da pontuação total de EBD entre pacientes com e sem ideação suicida e a média dos sentimentos e expectativas da subescala EBD em relação ao futuro e perda de motivação e esperança em termos de subescalas entre os grupos com e sem ideação suicida, a pontuação teve uma diferença significativa. Quando o IRV foi avaliado em termos de pontuações totais, o escore médio de ideação suicida foi de 243,74 ± 32,28, enquanto o escore médio de ideação não suicida foi de 267,27 ± 24,36. Houve uma relação significativa entre os dois grupos. Fatores de risco para ideação suicida em idosos foram desesperança, baixo nível de educação, baixo nível de razões para viver, distúrbio de ansiedade generalizada e transtorno depressivo comórbido.

Major depressive disorder is associated with fragmented QRS.

Objective There is a close link between major depressive disorder (MDD) and cardiovascular disease (CVD). Increasing oxidative stress, changes in hypothalamic-pituitary-adrenal axis and platelet clotting cascade may lead to subclinical myocardial damage in MDD patients without overt CVD. The aim of the study was to investigate whether MDD is associated with fragmented QRS (fQRS) on electrocardiogram (ECG) which may reflect myocardial fibrosis/scarring and ischaemia. Methods and results A total of 66 MDD patients without overt CVD and 35 age- and sex-matched control subjects were enrolled in this study. Twelve-lead surface ECGs were analysed for the presence of fQRS and echocardiographic examination was performed for each individual. Multivariate logistic regression analysis was used to assess the relationship between MDD and fQRS. The baseline characteristics in terms of age, gender, body mass index and cardiovascular risk factors were comparable in the groups (all P values >0.05). Left ventricular ejection fraction, left ventricular wall thickness and diastolic blood pressure were also similar in the two groups. The presence of fQRS was more prevalent (P < 0.001) and SBP values (P = 0.007) were higher in patients with MDD compared to controls. Moreover, multivariate binary logistic regression analysis indicated the recurrent MDD as the only independent predictor of fQRS on ECG (beta =0.196, 95% CI 0.046 - 0.827, P = 0.014). Conclusion The presence of fQRS on the ECG is associated with MDD, and may be a beneficial tool for detecting subclinical cardiac damage in this population.

Comparison of three different second-line quadruple therapies including bismuth subcitrate in Turkish patients with non-ulcer dyspepsia who failed to eradicate Helicobacter pylori with a 14-day standard first-line therapy.

BACKGROUND AND AIM: Many studies have reported poor results with standard first-line treatment for Helicobacter pylori. Second-line regimens that may overcome bacterial resistance can minimize side-effects and optimize compliance. The aim of this study was to evaluate the efficacy of proton pump inhibitor (PPI) and bismuth subcitrate-based quadruple therapy, after failure of a PPI plus clarithromycin and amoxicillin as first-line therapy. METHODS: Patients who failed to eradicate the infection after initial therapy were randomly separated into three groups. The first group received lansoprazole, bismuth subcitrate, metronidazole and amoxicillin (LBMA); in the second group metronidazole was replaced by tetracycline (LBTA); and the third group was given metronidazole and tetracycline in addition to same doses of lansoprazole and bismuth subcitrate (LBMT). RESULTS: In the LBMA group, the eradication rate was 74.7% and was significantly related to sex, with no relationship to age. In the LBTA group the eradication rate was 81.5% with similar rates in males and females. No relation to sex or age was observed. In the LBMT group the eradication rate was 82.1% with no difference between women and men and it was not related to age, either. Eradication rates in study groups were similar (P > 0.05). CONCLUSION: A-14-day regimen of lansoprazole, bismuth subcitrate and antibiotic pairs, tetracycline-amoxicillin and tetracycline-metronidazole, is an effective quadruple therapy after one failed course of standard triple therapy. The evaluation of tolerability of and compliance with quadruple therapy needs further studies.

Large vesicula seminalis cyst: a very rare cause of constipation and male infertility.

We report a 35-year-old male patient with chronic constipation and infertility for 4 years. Spermiogram revealed severe oligospermia. An external mass compressing the rectum was found during rectal examination and flexible rectosigmoidoscopy. Abdominal computed tomography showed a presacral cystic mass which displaced the bladder anteriorly. The cyst was completely removed with open surgery. Histopathologic analysis revealed a cystic lesion covered with squamous epithelium including polymorphonuclear leukocytes, macrophages and sperm cells. After the operation, the patient's symptoms were relieved. We considered that the constipation was caused by external compression by the vesicula seminalis cyst. In cases of constipation with infertility, vesicula seminalis cyst should be kept in mind.

Systemic markers of lipid peroxidation and antioxidants in patients with nonalcoholic Fatty liver disease.

OBJECTIVES: The aim of the present study was to examine the systemic parameters of oxidative stress and antioxidants in patients with nonalcoholic fatty liver disease and investigate the relationship between these parameters and clinical and biochemical outcomes. METHODS: Fifty-one male patients with nonalcoholic fatty liver disease (group I), 30 age-matched and body mass index (BMI)-matched healthy male subjects, and 30 age-matched male patients with chronic viral hepatitis (group II) were enrolled in the study. RESULTS: Increased systemic levels of malondialdehyde and depletion of antioxidants such as coenzyme Q10, CuZn-superoxide dismutase, and catalase activity were observed in group I. Coenzyme Q10 and CuZn-superoxide dismutase correlated negatively with increasing necroinflammatory activity and fibrosis. Body fat was negatively associated with plasma coenzyme Q10 levels, while an inverse association was found between plasma catalase levels and TG. However, LDL was positively associated with plasma malondialdehyde levels. CuZn-superoxide dismutase levels were negatively associated with glucose, insulin, and HOMA-IR. In addition, the levels of CuZn-superoxide dismutase correlated significantly in a negative manner with BMI. CONCLUSIONS: Our results concerning correlations suggest that disturbances in BMI, body fat, and lipid metabolism may contribute to altered oxidative status in NAFLD, and insulin resistance may be related to decreased antioxidants in NAFLD as well as products of lipid peroxidation. However, although our results suggest interesting correlations, this different mostly "weak" relationships must be taken with caution.

Continuity of cytokine activation in patients with familial Mediterranean fever.

Familial Mediterranean fever (FMF) is a recessively inherited inflammatory disorder, characterized by recurrent attacks of fever and polyserositis. It has been considered that miscellaneous cytokines take part in the pathogenesis of the disease. The aim of this study was to investigate serum levels of soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), and interleukin-10 (IL-10) in patients with FMF. The study included 42 patients with FMF (3 females, 39 males, mean age: 24.43 years) and 20 healthy volunteers as the control group (18 males, 2 females, mean age: 23.2 years). The patients were chosen according to Eliakim criteria. After recording their history and performing an examination, leukocyte counts, erythrocyte sedimentation rates (ESR), C-reactive protein (CRP), fibrinogen, sIL-2R, IL-6, and IL-10 levels were measured before and during attacks. A significant increase was found in leukocyte ( p<0.001), ESR ( p<0.001), CRP ( p<0.001), and fibrinogen ( p<0.001) levels of the patient group in the attack period compared to those in the quiescent state. sIL-2R ( p=0.019) and IL-6 ( p<0.001) levels showed significant increases during attacks compared to the levels before an attack. There was no significant difference between IL-10 levels. The levels of the three cytokines were significantly high both before and during the attacks compared to the control group. As a result, the elevation of sIL-2R and IL-6 levels both before and during the attacks compared to control group suggests the existence of continuous cytokine activation in the patients. No significant increase in the IL-10 levels in spite of the significant rise of sIL-2R and IL-6 during attacks supports the notion of inflammation and also reveals that compensation by anti-inflammatory IL-10 does not seem to occur.

Ulcerative colitis case beginning during pregnancy in a patient with antiphospholipid antibody syndrome.

It is well known that there may be an increased tendency for thrombosis in inflammatory bowel disease (IBD). This study presents a case with antiphospholipid antibody syndrome with ulcerative colitis diagnosed during pregnancy. A 30-year-old female patient, in her 6th week of pregnancy, applied to our clinic with complaints of abdominal pain and bloody diarrhea. She had a history of three abortions. She had been given aspirin and heparin treatment due to high levels of anticardiolipin antibody (ACA) in previous examinations that led to the diagnosis of antiphospholipid antibody syndrome. As the left colonoscopic examination of the patient showed ulcerative colitis, aspirin treatment was replaced with mesalazine (750 mg/day, in 3 equal doses). There was a significant relief in complaints of the patient. Medical treatment was interrupted three days before delivery. The patient delivered a baby, at full-term, of 3.6 kg by cesarean section. No adverse effects were observed in the mother or the baby due to the medical treatment. After delivery, mesalazine treatment was restarted. This case is interesting due to the co-diagnosis of IBD in a pregnant woman with antiphospholipid antibody syndrome. Successful and uncomplicated treatment of the patient with mesalazine should also be noted.
