Postoperative Pain Following Transoral Thyroidectomy via Vestibular Approach and Cervical Thyroidectomy: A Systematic Review and Meta-Analysis.

Transoral endoscopic thyroidectomy via the vestibular approach (TOETVA) represents a minimally invasive alternative to traditional open thyroidectomy (OT). The objective of this systematic review and meta-analysis was to comprehensively analyze and compare postoperative pain outcomes between conventional open thyroidectomy (COT) and TOETVA. We conducted a systematic search across multiple databases, including PubMed, Medline, Elton B. Stephens Company (EBSCO), and Google Scholar, to identify cohorts and randomized trials comparing postoperative pain outcomes between patients undergoing transoral endoscopic thyroidectomy via the vestibular approach (TOETVA) and those undergoing conventional thyroidectomy. The search period spanned from the earliest available article up to January 15, 2022. Keywords such as "scarless thyroidectomy," "endoscopic transoral via vestibular thyroidectomy," "conventional thyroidectomy," "transcervical thyroidectomy," "postoperative pain," and "visual analog pain score" were utilized to retrieve relevant studies. A total of 1,291 patients from 11 studies were included in our analysis, with 10 studies originating from Asia and one from Europe. Among these studies, seven were prospective, while four were retrospective. The primary outcome measure was postoperative pain. Various statistical tests were also performed for data analysis, including the Chi-square and random effects model. The Newcastle Ottawa Scale was used to assess the quality of studies. There was no significant statistical difference observed between the endoscopic transoral vestibular route and the conventional cervical approach in terms of visual analog scale (VAS) score, with an odds ratio of -0.37 and a 95% confidence interval ranging from -0.9 to 0.17. The overall effect had a P-value of 0.18. However, substantial heterogeneity was noted, with an I2 value for heterogeneity of 98% and a P-value for heterogeneity of less than 0.001. The Chi-square value was calculated as 364.02, and the main difference was 9. In comparison, TOETVA exhibited lower pain levels on the first day post-operation compared to conventional thyroidectomy, with an odds ratio of -1.36 and a 95% confidence interval ranging from -2.65 to -0.06. Transoral endoscopic thyroidectomy via the vestibular approach demonstrated superior outcomes compared to conventional thyroidectomy in terms of postoperative pain management on the first day following surgery. However, when considering overall pain management throughout the recovery period, no significant difference was observed between the two approaches. More extensive studies evaluating pain levels on the day of surgery and controlling for analgesic interventions are warranted.

Effects of Beta Lactams on Behavioral Outcomes of Substance Use Disorders: A Meta-Analysis of Preclinical Studies.

INTRODUCTION: Preclinical studies demonstrated that beta-lactams have neuroprotective effects in conditions involving glutamate neuroexcitotoxicity, including substance use disorders (SUDs). This meta-analysis aims to analyze the existing evidences on the effects of beta-lactams as glutamate transporter 1 (GLT-1) upregulators in animal models of SUDs, identification of gaps in the literature, and setting the stage for potential translation into clinical phases. METHODS: Meta-analysis was conducted on preclinical studies retrieved systematically from MEDLINE and ScienceDirect databases. Abused substances were identified by refereeing to the National Institute on Drug Abuse (NIDA). The results were quantitatively described with a focus on the behavioral outcomes. Treatment effect sizes were described using standardized mean difference, and they were pooled using random effect model. I2-statistic was used to assess heterogeneity, and Funnel plot and Egger's test were used for assessment of publication bias. RESULTS: Literature search yielded a total of 71 studies that were eligible to be included in the analysis. Through these studies, the effects of beta-lactams were evaluated in animal models of nicotine, cannabis, amphetamines, synthetic cathinone, opioids, ethanol, and cocaine use disorders as well as steroids-related aggressive behaviors. Meta-analysis showed that treatments with beta-lactams consistently reduced the pooled undesired effects of the abused substances in several paradigms, including drug-self administration, conditioned place preference, drug seeking behaviors, hyperlocomotion, withdrawal syndromes, tolerance to analgesic effects, hyperalgesia, and hyperthermia. CONCLUSION: This meta-analysis revealed that enhancing GLT-1 expression in the brain through beta-lactams seemed to be a promising treatment approach in the context of substance use disorders, as indicated by results in animal models.

A Physiologically Based Pharmacokinetic Model to Predict Systemic Ondansetron Concentration in Liver Cirrhosis Patients.

INTRODUCTION: Ondansetron is a drug that is routinely prescribed for the management of nausea and vomiting associated with cancer, radiation therapy, and surgical operations. It is mainly metabolized in the liver, and it might accumulate in patients with hepatic impairment and lead to unwanted adverse events. METHODS: A physiologically based pharmacokinetic (PBPK) model was developed to predict the exposure of ondansetron in healthy and liver cirrhosis populations. The population-based PBPK simulator PK-Sim was utilized for simulating ondansetron exposure in healthy and liver cirrhosis populations. RESULTS: The developed model successfully described the pharmacokinetics of ondansetron in healthy and liver cirrhosis populations. The predicted area under the curve, maximum systemic concentration, and clearance were within the allowed twofold range. The exposure of ondansetron in the population of Child-Pugh class C has doubled in comparison to Child-Pugh class A. The dose has to be adjusted for liver cirrhosis patients to ensure comparable exposure to a healthy population. CONCLUSION: In this study, the developed PBPK model has described the pharmacokinetics of ondansetron successfully. The PBPK model has been successfully evaluated to be used as a tool for dose adjustments in liver cirrhosis patients.

Arabic translation, cross cultural adaptation, and validation of Foot Health Status Questionnaire among Saudi individuals with plantar fasciitis.

BACKGROUND: Measuring quality of life (QoL) plays an essential role in enabling meaningful cross-cultural comparisons. The Foot Health Status Questionnaire (FHSQ) is a valid tool for assessing both foot-specific and general health-related quality of life (HrQoL), making it suitable for evaluating Plantar Fasciitis (PF) patients. METHODOLOGY: The aim of this study is to translate the FHSQ into Arabic following methodological assessments of the translation procedure. The translation was done using forward and back translation. A pre-test questionnaire was distributed among 50 patients, resulting in the final FHSQ-Ar version, which then underwent various psychometric evaluations among 87 persons with PF, including internal consistency, dimensionality, reliability, interpretability, and construct validity against the 100-mm Visual Analogue Scale (VAS). RESULTS: Internal consistency was adequate, ranging from 0.70 to 0.92. Reliability values ranged from 0.69 to 0.80, with a poor standard error of measurement (individual) but an acceptable standard error of measurement (group). Two domains exhibited floor effects, while one domain showed a ceiling effect. Regarding validity, three out of four hypothesized correlations with VAS scores were confirmed. Factor analysis revealed four dimensions, and confirmatory factor analysis demonstrated good fit (comparative fit index = 0.98, standardized root mean square = 0.06). CONCLUSION: The psychometric properties of the FHSQ-Ar were satisfactory. Further validation for other diseases may be warranted.

Protective effect of diosmin against doxorubicin-induced nephrotoxicity.

Doxorubicin (Dox) is an anthracycline antibiotic that is primarily used for treating various solid tumors including that of pulmonary, ovary, breast, uterine, cervix, and several blood cancers. However, nephrotoxicity associated with Dox treatment limits its clinical use. Administration of Dox in combination with compounds exhibiting antioxidant properties are being used to minimize the side effects of Dox. Diosmin is a flavonoid glycoside with numerous beneficial properties that is found in the pericarp of many citrus fruits. Diosmin has demonstrated antioxidant, anti-inflammatory, and anti-apoptotic effects in response to various insults, although the exact mechanism remains unknown. Therefore, this study was designed to evaluate the effect of diosmin in preventing kidney damage in response to Dox treatment. Male Wistar rats were randomly divided into four groups: control group, Dox group (20 mg/kg, i.p.), Dox plus low-dose diosmin group (100 mg/kg orally), and Dox plus high-dose diosmin group (200 mg/kg orally). A single intraperitoneal injection of Dox resulted in kidney damage as evidenced by significant alterations in kidney markers, histological abnormalities, and the attenuation of antioxidant defense mechanisms (GSH, SOD, and CAT). Moreover, Dox treatment significantly altered the expression of oxidative stress, inflammatory, and anti-apoptotic protein markers. Diosmin pretreatment alleviated Dox-induced nephrotoxicity by ameliorating the antioxidant mechanism, decreasing inflammation and apoptosis, and restoring kidney architecture. In conclusion, our results indicate that diosmin is a promising therapeutic agent for the prevention of nephrotoxicity associated with DOX.

Minimally invasive versus open surgery for the correction of adult degenerative scoliosis: a systematic review.

While open surgery has been the primary surgical approach for adult degenerative scoliosis, minimally invasive surgery (MIS) represents an alternative option and appears to be associated with reduced morbidity. Given the lack of consensus, we aimed to conduct a systematic review on available literature comparing MIS versus open surgery for adult degenerative scoliosis. PubMed, Embase, and Cochrane databases were searched through December 16, 2019, for studies that compared both MIS and open surgery in patients with degenerative scoliosis. Four cohort studies reporting on 350 patients met the inclusion criteria. In two studies, patients undergoing open surgery were younger and had more severe disease at baseline as compared with MIS. Patients who underwent MIS had less blood loss, shorter length of stay, and a reduced rate of complications and infections. Both MIS and open surgery resulted in a significant change in pain and disability scores and both approaches provided significant correction of deformity in all studies, although open surgery was associated with a greater change in pelvic incidence-lumbar lordosis mismatch (PI-LL) and sagittal vertical axis (SVA) in two and three studies, respectively. In patients with adult degenerative scoliosis undergoing surgery, both MIS and open approaches appeared to offer comparable improvements in pain and function. However, MIS was associated with better safety outcomes, while open surgery provided greater correction of spinal deformity. Further studies are needed to identify specific subset of patients who may benefit from one approach versus the other.
