Background: Although laparoscopic adjustable gastric bands (LAGBs) have been shown to be efficacious, their long-term usefulness has been questioned. This study examined the fate of LAGBs in a unit with over a decade of experience in their use. Patient factors related to the need for, and timing of, band removal were investigated.
Methods: A prospectively maintained database was used to identify all patients with a LAGB. Patient demographics, need for band removal and band survival were examined. Logistic regression modelling was done and Kaplan-Meier curves were calculated for band survival.
Results: Between 2000 and 2012, 674 bands were placed in 665 patients. Of these, 143 (21.2 per cent) were removed. There was no difference in rates of removal by sex (P = 0.910). The highest rates of removal were in patients aged less than 40 years (26.7 per cent), and those with a BMI greater than 60 kg/m2 (28.6 per cent). Earlier band removal was seen in younger patients (P = 0.002). Rates of removal increased linearly by earlier year of placement. Of bands placed 4 or more years previously, 35.0 per cent required removal. Eighty-three patients (58.0 per cent) who had a LAGB removed went on to have a further bariatric procedure (band to bypass, 66; band to sleeve, 17).
Conclusion: Even in experienced hands LAGB does not appear to be a definitive solution. In a large number of patients there appears to be a finite 'band life', with the majority of patients requiring conversion to a further bariatric procedure.

MXene-based (nano)materials have recently emerged as promising solutions for antibiotic photodegradation from aquatic environments, yet they are limited by scalability, stability, and selectivity challenges in practical settings. We formulated FeO-SiO/MXene ternary nano-photocomposites via coupled wet impregnation and sonochemistry approach for optimised tetracycline (TC) removal (the second most used antibiotic worldwide) from water using response surface methodology-central composite design (RSM-CCD). The photocatalysts containing various loading of FeO/SiO (5-45 wt%) on the MXene with a range of calcination temperatures (300-600 °C) via RSM optimisation were synthesised, characterised regarding crystallinity properties, surface morphology, binding energy, and light absorption capability, and analysed for TC degradation efficiency.

Designing catalysts with well-defined active sites with chemical functionality responsive to visible light has significant potential for overcoming scaling relations limiting chemical reactions over heterogeneous catalyst surfaces. Visible light can be leveraged to facilitate the removal of strongly bound species from well-defined single cationic sites (Rh) under mild conditions (323 K) when they are incorporated within a photoactive perovskite oxide (Rh-doped SrTiO). CO, a key intermediate in many chemistries, forms stable geminal dicarbonyl Rh complexes (Rh(CO)), that could act as site blockers or poisons during a catalytic cycle.

Head and neck squamous cell carcinoma (HNSCC) are the most common type of head and neck tumor that severely threatens human health due to its highly aggressive nature and susceptibility to distant metastasis. The diagnosis of HNSCC currently relies on biopsy and histopathological examination of suspicious lesions. However, the early mucosal changes are subtle and difficult to detect by conventional oral examination.

Organic pollutants removal via a polymerization transfer (PT) pathway based on the use of single-atom catalysts (SACs) promises efficient water purification with minimal energy/chemical inputs. However, the precise engineering of such catalytic systems toward PT decontamination is still challenging, and the conventional SACs are plagued by low structural stability of carbon material support. Here, we adopted magnesium oxide (MgO) as a structurally stable alternative for loading single copper (Cu) atoms to drive peroxymonosulfate-based Fenton-like reactions.
