Epub 2021 Nov 12. ABSTRACT Age-related hearing loss (ARHL) is a major public health concern, which is characterized by gradual, progressive sensorineural hearing loss and deterioration of sound localization, with no effective treatment available to date. The aim of the present study was to evaluate the efficacy of resveratrol to prevent and treat ARHL. For this purpose, 32 male C57BL/6 mice were assigned to four groups: Early treatment, late treatment, control and sham control. The experiment lasted for 15 months. Treatment was started at three months of age in the early treatment group and at sixth months in the late treatment group. The auditory brainstem response test was performed once every three months. At the end of the study period, inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, NF-κB, Bcl-2, Bcl-xL, Bax, Bcl-2 homologous antagonist/killer (Bak), caspase-3 and caspase-9 levels in the cochlear tissues of the animals were analyzed by reverse transcription-quantitative PCR. Hearing thresholds of the mice in the early treatment group were better than those in the other groups (P<0.001) at the end of the study. However, hearing levels in the late treatment group were not significantly different from those in the control groups (P>0.05), although mean thresholds were lower. The threshold shift in the early treatment group was significantly lower at all frequencies when compared with those in the control groups (P<0.001). The mRNA expression levels of pro-apoptotic genes Bax and Bak were lower (P<0.05), anti-apoptotic genes Bcl-2 and Bcl-xL were higher (P<0.05), NF-κB, COX-2 and iNOS as genes that have a role in inflammation and caspase-3 and caspase-9 as genes with a vital role in apoptosis were lower (P<0.05) in the early treatment group when c ompared with the late treatment and control groups. These results suggested that resveratrol is effective in the prevention of ARHL, particularly when started prior to the beginning of hearing loss.

Determining whether previous SWL for ureteric stones influences the results of ureteroscopy as the second-line treatment: A clinical study

xlomafota13 shared this article with you from Inoreader Determining whether previous SWL for ureteric stones influences the results of ureteroscopy as the second-line treatment: A clinical study Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):38. doi: 10.3892/etm.2021.10960. Epub 2021 Nov 11. ABSTRACT The purpose of the study was to establish whether shock wave lithotripsy (SWL) is a potential harmful first-line treatment for ureteric stones where ureteroscopy (URS) is necessary as a second-line treatment. Medical records of patients with ureteric stones who underwent either URS as the only therapy applied or SWL followed by URS over two years were retrospectively evaluated. In total, 158 patients were included: 79 patients in Group A (no SWL) and 79 in Group B (prior SWL before URS). There was no difference in major complications, Group A had higher stone-free rates, Group B had higher rates of ureteral edema and similar intraoperative ureteral lesions. In conclusion, the failure of SWL for lumbar or pelvic ureteral lithiasis does not appear to have a negative effect on the rate of intraoperative complications or the success rate of semi-rigid retrograde URS for this category of calculi, with the same safety profile as first-line endourological intervention.

Protective role of lidocaine against cerebral ischemia-reperfusion injury: An in vitro study

xlomafota13 shared this article with you from Inoreader Protective role of lidocaine against cerebral ischemia-reperfusion injury: An <em>in vitro</em> study Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):42. doi: 10.3892/etm.2021.10964. Epub 2021 Nov 12. ABSTRACT Lidocaine, a local anesthetic, is a valuable agent for the treatment of neuronal ischemia/reperfusion (I/R) injury. The aim of the present study was to investigate the role of lidocaine in oxygen-glucose deprivation/reperfusion (OGD/R)-induced cortical neurons and explore the related molecular mechanisms. Cerebral cortical neurons were isolated from Sprague-Dawley rat embryos and stimulated with OGD/R to establish an in vitro I/R injury model. Subsequently, neuronal cell viability, cytotoxicity and apoptosis were evaluated by performing the MTT assay, lactate dehydrogenase (LDH) assay and flow cytometry, respectively. The results suggested that OGD/R exposure significantly decreased cerebral cortical neuron cell viability, accelerated LDH release and induced cell apoptosis compared with control neurons, indicating that cerebral I/R injury wa s stimulated by OGD/R treatment. Further investigation indicated that 10 µM lidocaine significantly enhanced neuronal cell viability, and reduced LDH release and neuronal cell apoptosis in OGD/R-exposed cells compared with the OGD/R + saline group, which indicated that lidocaine displayed neuroprotective effects against I/R damage. In addition, the findings of the present study suggested that OGD/R exposure significantly decreased Bcl-2 and Bcl-xl protein expression levels, but increased Bax protein expression levels, the Bax/Bcl-2 ratio and caspase-3 activity compared with control neurons. However, lidocaine reversed OGD/R-mediated alterations to apoptosis-related protein expression. Furthermore, the results of the present study indicated that lidocaine increased Wnt3a, β-catenin and cyclin D1 expression levels in OGD/R-exposed cells compared with the OGD/R + saline group, thus activating the Wnt/β-catenin signaling pathway. The findings of the present study suggested that lidoc aine served a protective role in OGD/R-triggered neuronal damage by activating the Wnt/β-catenin signaling pathway; therefore, lidocaine may serve as a potential candidate for the treatment of cerebral I/R injury.

Expression and clinical significance of lncRNA TCL6 in serum of patients with preeclampsia

xlomafota13 shared this article with you from Inoreader Expression and clinical significance of lncRNA TCL6 in serum of patients with preeclampsia Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):41. doi: 10.3892/etm.2021.10963. Epub 2021 Nov 12. ABSTRACT Preeclampsia is a common syndrome in pregnancy and a leading cause of mortality of pregnant females and their infants. To investigate the diagnostic and prognostic utility of lncRNA T-cell leukemia/lymphoma 6 (TCL6) in patients with preeclampsia, 120 singleton pregnant females with preeclampsia and another 100 healthy pregnant control subjects were analyzed in the present study. The expression of lncRNA TCL6 in the serum of the included patients was detected. Receiver operating characteristic curve analysis was applied to evaluate the efficiency of lncRNA TCL6 in terms of preeclampsia diagnosis and grading. Kaplan-Meier analysis was adopted to assess the effect of lncRNA TCL6 expression on the rate of adverse pregnancy. Multivariate logistic regression was used to determine high-risk factors of adverse pregnancy. The results indicated that lncRNA T CL6 was significantly increased in the serum of patients with preeclampsia. Furthermore, TCL6 was elevated in subgroups of patients with early-onset or severe preeclampsia and with Haemolysis, Elevated Liver enzymes and Low Platelet count syndrome in comparison with other patients with preeclampsia. High expression of TCL6 in pregnant females corresponded to a higher rate of adverse pregnancy outcomes. Severe preeclampsia, early-onset preeclampsia and high TCL6 expression were identified as independent risk factors for adverse pregnancy outcomes. For each unit increase in TCL6 expression, a 9.5-fold increase of the risk of adverse maternal and fetal outcomes was determined. Collectively, high expression of lncRNA TCL6 may assist the diagnosis and grading of preeclampsia and may be adopted as an independent risk factor for adverse pregnancy outcomes.

Isolated liver trauma: A clinical perspective in a non-emergency center for liver surgery

xlomafota13 shared this article with you from Inoreader Isolated liver trauma: A clinical perspective in a non-emergency center for liver surgery Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):39. doi: 10.3892/etm.2021.10961. Epub 2021 Nov 11. ABSTRACT The management of liver trauma is, currently, still heterogeneous ranging from conservative to major invasive liver resections. When appropriate, these cases should be referred to a regional care center. The objective of this study was to analyze the expertise of a non-emergency center for liver surgery from Romania after initial stabilization in county hospitals. This study is a monocentric, retrospective, observational study, including 12 patients with hepatic trauma after a car accident, admitted between 2015 and 2019. We analyzed various clinical and biochemical data as independent variables, and the main outcome was considered the intensive care unit (ICU) length of stay. Our results revealed that intubation status at admission, norepinephrine infusion during surgery, hyperfibrinogenemia and duration of mechanical ventilation in patients with isolated liver trauma were correlated with prolonged ICU length of stay. Further prospective, more comprehensive studies are needed in order to evaluate the exact prognostic factors in terms of short- and long-term mortality.

Epub 2021 Nov 10. ABSTRACT Acute kidney injury (AKI) is one of the most severe complications of SARS-CoV-2 infection. In a retrospective study, we aimed to describe the influence of COVID-19-related factors on the severity, outcome and timing of AKI in 268 patients admitted in two large COVID-19-designated university hospitals over a period of 6 months. In the univariate analysis, there was a significant relationship between KDIGO stage and the extension of COVID-19 pneumonia on computed tomography (CT), need for oxygen supplementation, serum levels of ferritin, interleukin-6, and procalcitonin, but none of these variables had a value for predicting KDIGO stage in multinomial regression. The odds of recovery of renal function were significantly diminished by d-dimer values. Lack of immunomodulatory treatment was found to be correlated with increased need for renal replacemen t therapy (RRT). Compared with AKI at admission, hospital-acquired AKI was predicted by the severity of lung damage on CT, evolved more frequently with incomplete recovery of renal function, and was significantly associated with antiviral therapy.
