Postoperative pulmonary complications in patients with chronic obstructive pulmonary disease undergoing primary laparoscopic bariatric surgery: an MBSAQIP analysis.

Background: Recent research has shown beneficial effects of bariatric surgery (BaS) on the risk of developing acute exacerbations of chronic obstructive pulmonary disease (COPD). However, this patient population may be at increased risk of complications, especially postoperative pulmonary complications (PPC).

Objectives: To analyze the incidence of PPC in patients with COPD undergoing BaS.

Biowaste rice husk derived cellulosic hydrogel incorporating industrial cotton waste nonwoven for wound dressing.

Bio-wastes are organic materials achieved through biological sources. The rice crop produces a substantial amount of biowaste in the form of rice husk, which is rich in cellulose. In this research, cellulose was extracted from rice husk by alkalization and bleaching process.

Development of sustainable flame-retardant bio-based hydrogel composites from hemp/wool nonwovens with chitosan-banana sap hydrogel.

Flame retardant (FR) finishing is crucial for developing protective textiles, traditionally relying on halogen, phosphorus, and phosphorus-nitrogen chemistries, which have limitations like toxicity and fabric stiffening. Innovative approaches such as nanotechnology, plasma treatments, and natural resource-based finishes are being explored to achieve sustainable FR textiles. This study presents the development and comprehensive characterization of hydrogel composites made from nonwoven fabrics composed of various hemp/wool blends (70/30, 80/20, and 90/10).

Hydroentangled waste cotton non-woven based alginate hydrogel wound dressing for high wound exudates.

Hydrogels are used in modern wound dressings due to their ability to provide comfort with quick healing. However, poor mechanical properties of hydrogels limit their availability in commercial wound dressings. Nonwovens are highly porous, strong, and flexible structures that can provide support to hydrogels without compromising their properties.

Impact of selective serotonin reuptake inhibitors on weight loss after vertical sleeve gastrectomy.

Background: Mental health disorders, such as depression, are prominent within the bariatric population, with antidepressants ranking among the most frequently prescribed medications.

Objectives: Our surgery aimed to investigate selective serotonin reuptake inhibitor (SSRI) effects on weight loss in patients undergoing vertical sleeve gastrectomy (VSG).

Setting: University affiliated Community Hospital, United States.
