Negative pressure ventilation (NPV), when used as an adjuvant to pulmonary rehabilitation, improves lung function, increases exercise capacity, and reduces exacerbations. The aim of this study was to determine whether maintenance NPV improves long-term clinical outcomes and reduces mortality in patients with chronic obstructive pulmonary disease (COPD). Between 2003 and 2009, 341 patients were treated for COPD either with or without hospital-based NPV. We measured forced expiratory volume in one second (FEV1), 6-min walking distance (6MWD), and oxygen saturation by pulse oximetry (SpO2) during a 6-min walk test (6MWT) every 3–6 months. Desaturation (D) during the 6MWT was defined as a reduction in SpO2 of ≥10% from baseline. The NPV group had a better survival outcome than the Non-NPV group. The 8-year survival probabilities for the NPV and Non-NPV groups were 60% and 20%, respectively (p < 0.01). Baseline desaturation was a significant risk factor for death, and the risk of death increased with desaturation severity (SpO2 80~89: hazard ratios (HR) 2.7, 95% confidence interval (CI) 1.4–5.3; SpO2 < 80: HR 3.1, 95% CI 1.3–7.4). The NPV group had a slower decline in lung function and 6MWD. The NPV + D and Non-NPV+D had a threefold and fourfold increase in the risks of all-cause mortality compared with the NPV-ND, respectively. Maintenance non-invasive NPV reduced long-term mortality in COPD patients. The desaturating COPD patients had an increased mortality risk compared with non-desaturating COPD patients.

Surgical site infection (SSI) and incisional hernia are common complications after major pancreatectomy. We investigated the effects of negative pressure wound therapy (NPWT) on short-and long-term wound outcomes in patients undergoing pancreatectomy. A randomized controlled trial comparing the effect of NPWT with standard surgical dressing (SSD) on wounds was performed in 265 patients undergoing open gastrointestinal resections from 2012 to 2016. We performed a subset analysis of 73 patients who underwent pancreatectomy. Wound complications in the first 30 days and incisional hernia rates were assessed. There were 33 (45%) female patients in the study and the average BMI was 27.6. The pancreaticoduodectomy rate was 68 per cent, whereas 27 per cent of patients underwent distal or subtotal pancreatectomy, and 4 per cent total pancreatectomy. Incisional hernia rates were 32 per cent and 14 per cent between the SSD and NPWT groups, respectively (P = 0.067). In the SSD (n = 37) and NPWT (n = 36) cohorts, the superficial SSI, deep SSI, seroma, and dehiscence rates were 16 per cent and 14 per cent (P > 0.99), 5 per cent and 8 per cent (P = 0.67), 16 per cent and 11 per cent (P = 0.74), and 5 per cent and 3 per cent (P ≥ 0.99), respectively. After adjusting for pancreatic fistula and delayed gastric emptying, no statistically significant differences in the primary outcomes were observed. These findings were true irrespective of the type of resection performed. Short- and long-term wound complications were not improved with NPWT. We observed a trend toward decreased incisional hernia rates in patients treated with NPWT. Owing to the multifactorial nature of wound complications, it is yet to be determined which cohorts of pancreatectomy patients will benefit from NPWT.

1. Previous histological studies have demonstrated partial reinnervation of the human transplanted kidney. However, it remains unknown whether this reinnervation is of any functional significance. 2. The effects of noradrenaline infusion (2 μgh−1kg−1) and lower body negative pressure (−27 mmHg) on renal haemodynamics, sodium excretion and tubular function were investigated in 25 renal transplant recipients and 10 normal subjects. Sixteen of the transplant recipients had all been transplanted for more than 27 months, and nine had all been transplanted for less than 2 months. 3. After an overnight fast, the subjects were water-loaded, and clearance studies were performed with a 1 h baseline period, a 1 h period with noradrenaline infusion, another 1 h baseline period, and a final 1 h period with lower body negative pressure. 4. During noradrenaline infusion the relative decrease in effective renal plasma flow, glomerular filtration rate and clearance of lithium and sodium was significantly more pronounced in the long-term transplanted patients than in the control subjects. 5. Lower body negative pressure only depressed the glomerular filtration rate significantly in the control subjects. Further, the relative decrease in effective renal plasma flow and clearance of lithium and sodium was significantly greater in the control subjects than in the two groups of transplanted patients. 6. The present study thus demonstrated that in short- and long-term transplanted kidneys in man, supersensitivity to circulating noradrenaline and an inadequate response to lower body negative pressure was present. This strongly suggests that the human transplanted kidney remains functionally denervated.
