825 [95% confidence interval (CI) 0.823-0.827]. When per-lesion level PV and the presence of HRP were added to Model 1, the predictive value of the model improved the C-statistics to 0.895 [95% CI 0.893-0.897]. The model utilizing per-lesion level CCTA measures was superior to the model utilizing per-patient level CCTA measures in predicting the development of an obstructive lesion (p  less then  0.001). selleck kinase inhibitor Lesion-level analysis of coronary atherosclerotic plaques with CCTA yielded better predictive power for the development of obstructive CAD than the simple quantification of total coronary atherosclerotic burden at a per-patient level.Clinical Trial Registration ClinicalTrials.gov NCT0280341.

Adjustable gastric banding (AGB) is on the decline due to its relatively modest amount of expected weight loss, coupled with high rates of revision and complications such as band erosion. Management of eroded gastric bands can be challenging especially when complete intra-gastric erosion is followed by distal migration causing small bowel obstruction.

We present an endoscopic option of using a pediatric colonoscope to remove an eroded AGB causing jejunal obstruction.

Endoscopic removal of an eroded ABG causing bowel obstruction was successful.

Endoscopy remains a safe and relatively non-invasive approach to deal with such complications.

Obese patients have neurodegeneration of the optic nerve demonstrated by decreased peripapillary nerve fiber layer. Whether bariatric surgery reverses this neurodegenerative process has not been explored. We aimed to evaluate the impact of bariatric surgery in the structure of the retina and optic nerve.

Multicentric observational study. Obese patients scheduled for bariatric surgery were consecutively recruited and included in the study and evaluated before and 6-12months after the intervention. The retinal structure was evaluated as retinal thickness in the different retinal layers in the foveal, perifoveal, and parafoveal regions using optical coherence tomography. Choroidal thickness and optic nerve retinal nerve fiber layer thickness were also evaluated.

Eighty eyes from 40 participants were included. Globally, we found a significant thickening of the retina after bariatric surgery (foveal 273.5 (21.5) μm vs 280.0 (28.8) μm, p < 0.001; parafoveal 332.4 ± 17.8μm vs 336.6 ± 15.9μm, p = 0.003; perierve fiber layer remained unchanged after the surgery.

Effective postoperative analgesia is paramount in patients undergoing bariatric surgery, given their increased predisposition to narcotic-induced respiratory depression. Transversus abdominis plane (TAP) block has shown promise in the enhanced recovery pathway for several abdominal procedures. We performed a systematic review and meta-analysis to compare the effectiveness of TAP block in laparoscopic bariatric surgery.

PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until June 2020. All randomized trials that compared TAP blocks versus none in laparoscopic bariatric procedures were included. The primary outcome was narcotic consumption at 24h postoperatively, whilst secondary outcomes included postoperative pain scores at 24h, time to ambulation, postoperative nausea and vomiting (PONV) and complication rates. Random effects models were used to calculate pooled effect size estimates.

Seven randomized controlled trials were included, capturing 617 patients. There was high statistical heterogeneity across studies. On random effects analysis, there were no significant differences in narcotic consumption (MD -12.63mg, 95% CI = -31.67 to 6.41, p = 0.19), pain scores (MD -0.71, 95% CI = -1.93 to 0.50, p = 0.25) or complications (RD = -0.00, 95% CI = -0.03 to 0.03, p = 0.87) between TAP and no TAP groups. However, TAP was associated with significantly less time to ambulation (MD -2.22h, 95% CI = -3.89 to -0.56, p = 0.009) and PONV (OR = 0.13, 95% CI = 0.05 to 0.35, p < 0.0001).

TAP in laparoscopic bariatric surgery is associated with significantly less PONV and time to ambulation, but similar complication rates, narcotic usage and postoperative pain at 24h compared to no TAP.

Dibenzo-indole-bearing aristolactams are compounds that have been isolated from various plants species and which show several clinically relevant effects, including anti-inflammatory, antiplatelet, and anti-mycobacterial actions. However, the effect of these compounds on human immunodeficiency virus type 1 (HIV-1) infection has not yet been studied. In this study, we discovered an aristolactam derivative bearing dibenzo[cd,f]indol-4(5H)-one that had a potent anti-HIV-1 effect. A structure-activity relationship (SAR) study using nine synthetic derivatives of aristolactam identified the differing effects of residue substitutions on the inhibition of HIV-1 infection and cell viability. Among the compounds tested, 1,2,8,9-tetramethoxy-5-(2-(piperidin-1-yl)ethyl)-dibenzo[cd,f]indol-4(5H)-one (Compound 2) exhibited the most potent activity by inhibiting HIV-1 infection with a half-maximal inhibitory concentration (IC50) of 1.03 μmol/L and a half-maximal cytotoxic concentration (CC50) of 16.91 μmol/L (selectivity index, 16.45). The inhibitory effect of the compounds on HIV-1 infection was linked to inhibition of the viral replication cycle. Mode-of-action studies showed that the aristolactam derivatives did not affect reverse transcription or integration; instead, they specifically inhibited Tat-mediated viral transcription. Taken together, these findings show that several aristolactam derivatives impaired HIV-1 infection by inhibiting the activity of Tat-mediated viral transcription, and suggest that these derivatives could be antiviral drug candidates.
