RESUMO
OBJECTIVE: To examine the renoprotective effects of metabolic surgery in patients with established chronic kidney disease (CKD). BACKGROUND: The impact of metabolic surgery compared with glucagon-like peptide-1 receptor agonists (GLP-1RA) in patients with established CKD has not been fully characterized. METHODS: Patients with obesity (body mass index ≥30 kg/m 2 ), type 2 diabetes, and baseline estimated glomerular filtration rate (eGFR) 20-60 mL/min/1.73 m² who underwent metabolic bariatric surgery at a large US health system (2010-2017) were compared with nonsurgical patients who continuously received GLP-1RA. The primary end point was CKD progression, defined as a decline of eGFR by ≥50% or to <15 mL/min/1.73 m 2 , initiation of dialysis, or kidney transplant. The secondary end point was the incident kidney failure (eGFR <15 mL/min/1.73 m 2 , dialysis, or kidney transplant) or all-cause mortality. RESULTS: 425 patients, including 183 patients in the metabolic surgery group and 242 patients in the GLP-1RA group, with a median follow-up of 5.8 years (IQR, 4.4-7.6), were analyzed. The cumulative incidence of the primary end point at 8 years was 21.7% (95% CI: 12.2-30.6) in the surgical group and 45.1% (95% CI: 27.7 to 58.4) in the nonsurgical group, with an adjusted hazard ratio of 0.40 (95% CI: 0.21 to 0.76), P =0.006. The cumulative incidence of the secondary composite end point at 8 years was 24.0% (95% CI: 14.1 to 33.2) in the surgical group and 43.8% (95% CI: 28.1 to 56.1) in the nonsurgical group, with an adjusted HR of 0.56 (95% CI: 0.31 to 0.99), P =0.048. CONCLUSIONS: Among patients with type 2 diabetes, obesity, and established CKD, metabolic surgery, compared with GLP-1RA, was significantly associated with a 60% lower risk of progression of kidney impairment and a 44% lower risk of kidney failure or death. Metabolic surgery should be considered as a therapeutic option for patients with CKD and obesity.

INTRODUCTION: Obesity is a major risk factor for idiopathic intracranial hypertension (IIH). Effective therapeutics for preventing disease progression and alleviating symptoms are limited. This study aims to examine the effects of bariatric surgery on clinical outcomes of IIH. METHODS: We retrospectively collected data from the medical record of 97 patients with obesity and an existing diagnosis of IIH who underwent primary bariatric surgery at the Cleveland Clinic health system in the USA between 2005 and 2023. Pre- and postoperative data on presence of symptoms and clinical markers of IIH (headaches, visual field defects, papilledema, visual symptoms), intracranial pressure, and usage of IIH medications were compared. RESULTS: A total of 97 patients (98% female, median age 46.7 years, median BMI 48.3 kg/m2) with IIH who underwent bariatric surgery including Roux-en-Y gastric bypass (n = 66, 68%), sleeve gastrectomy (n = 27, 27.8%), and gastric banding (n = 4, 4.1%) were analyzed. In a median follow-up time of 3.0 years, the median total weight loss was 24% (interquartile range, 13-33%). There was a significant improvement in headache, papilledema, visual field deficits, and visual symptoms after bariatric surgery. The mean lumbar opening pressure before and after bariatric surgery was 34.8 ± 8.2 cm CSF and 24.2 ± 7.6 cm CSF, respectively, with a mean reduction of 10.7 cm CSF (95% confidence interval, 4.7 to 16.6), p = 0.003. The dosage of acetazolamide and topiramate, as well as the number of medications taken for IIH, decreased significantly after bariatric surgery (p < 0.001). CONCLUSION: For patients who have obesity, bariatric surgery is a viable treatment modality for alleviation or improvement of symptoms of IIH.
RESUMO
Intervertebral disc degeneration (IDD) is the main cause of low back pain, which is a healthcare concern associated with high social and economic burden. The current medical and surgical therapies are inadequate and ineffective. Several miRNAs have been identified that modulate (via up- or down-regulation) the pathogenesis of IDD through various signaling pathways. Understanding the nature of this regulation and their signaling pathways will enable researchers to manipulate miRNA regulation to develop miRNA-based therapies. The development of miRNA-based therapies opens a future window through which to decrease the IDD process or regenerate the intervertebral disc. In the near future, the obstacles associated with miRNA-based therapies will be overcome and these therapies will move from the bench to the bedside.

BACKGROUND: Acute pain control after supratentorial craniotomy is considered among the most important indicators of postoperative recovery. The aim of this study was to determine the effects of intravenous acetaminophen on postcraniotomy pain. METHODS: We searched databases including Embase, Scopus, Medline, Cochrane Library, and Web of Science until April 2019. Cochran Q test and I2 statistic were used to assess the heterogeneity across included clinical trials. Standardized mean difference (SMD) and 95% confidence interval (CI) were used to estimate pooled effect sizes. RESULTS: Out of 479 reports, 5 randomized controlled trials met the inclusion criteria and were appropriate for our meta-analysis, which included a total of 2635 patients. The pooled results of included clinical trials indicated that paracetamol intake significantly decreased rescue dose (SMD, -0.67; 95% CI, -1.15 to -0.19; P < 0.01; I2 = 90.0%), total dosage of rescue (SMD, -0.78; 95% CI, -1.18 to -0.37; P < 0.01; I2 = 86.0%), intensive care unit length of stay (SMD, -0.24; 95% CI, -0.44 to -0.04; P = 0.01; I2 = 0.0%), and visual analog scale score (SMD, -0.16; 95% CI, -0.31 to -0.00; P = 0.04; I2 = 71.7%) and increased patient satisfaction (SMD, 0.28; 95% CI, 0.14-0.43; P < 0.01; I2 = 10.2%) among patients with craniotomy. Time to rescue (SMD, 0.21; 95% CI, -0.42 to 0.85; P = 0.51; I2 = 94.3%) and hospital length of stay (SMD, -0.04; 95% CI, -0.24 to 0.16; P = 0.69; I2 = 0.0%) did not significantly change after paracetamol intake. CONCLUSIONS: The results of this systematic review and meta-analysis indicate that preoperative intravenous administration of acetaminophen is associated with decreased postoperative pain, need for rescue analgesics, and dosages of analgesics after craniotomy surgery.
