Compression stockings and travel-related DVT risk in airline passengers
The review pooled 12 randomized trials in 2,918 air travelers, at low, medium, and high risk of DVT. In the nine trials that put stockings on both legs, 2,637 participants had follow-up data: symptomless DVT was found in 3 of those who wore graduated compression stockings and 47 of those who did not (odds ratio 0.10, 95% CI 0.04 to 0.25; high-certainty evidence). Leg swelling was also reduced, on low-certainty evidence. No symptomatic DVT, pulmonary embolism, or death occurred in any included trial, so the review cannot speak to those outcomes, and every trial it included studied flights longer than five hours.

62 patients with early-stage chronic venous disease were randomized to four weeks of compression stockings or Kinesio taping, both alongside calf-pump and flexibility exercise. Stockings reduced pain and ankle, calf, knee, and thigh circumference significantly more than taping; walking distance and quality of life improved similarly in both groups.

An International Compression Club panel graded the evidence behind 25 recommendations. It recommends compression to relieve venous symptoms (Grade 1B) and to prevent leg swelling in people at risk, including during long flights (Grade 1B), and suggests compression during long-distance travel to reduce DVT risk in travelers who are already at raised risk (Grade 2B). It sets no single pressure for everyone: pressure should be the lowest that relieves symptoms and swelling.

A bovine collagen matrix vs saline-gauze care in stalled diabetic foot ulcers
A retrospective, exploratory subset analysis drawn from a randomized, controlled, multicenter trial in diabetic neuropathic foot ulcers that had failed to shrink by more than 30% during a two-week run-in of standard care. It compares 26 patients given a bovine dermal collagen matrix with 15 given daily saline-moistened gauze. Four weeks after a single application, 50% of the collagen group (13 of 26) had reached at least a 75% reduction in wound area, against 13% of the gauze group (2 of 15). Complete closure at 12 weeks — the harder endpoint — was 42% with the collagen matrix and 27% with gauze, a difference that did not reach statistical significance. No treatment-related adverse events were reported.

A systematic review of 16 randomized trials of dressings that inhibit matrix metalloproteinases — 13 of them collagen — in diabetic foot ulcers, venous leg ulcers, pressure ulcers, and mixed-origin wounds. Evidence of better wound closure, greater wound-size reduction, and shorter healing time exists for some of these dressings, and the authors note that trial quality varies considerably.

Hydrocolloid dressings in dermatology
A narrative review of where hydrocolloid dressings are used beyond chronic wound care: acute wounds including burns and surgical wounds, pressure ulcers, hypertrophic and keloid scarring, facial atopic dermatitis, and acne. The authors describe the moist, protective gel layer as the common mechanism, and note that the acne evidence is still early and limited.

A pilot trial in 20 people with mild-to-moderate acne, 10 per arm, comparing a hydrocolloid acne dressing with plain skin tape over one week. From day 3 onward the dressing group showed a greater reduction in overall acne severity and inflammation, along with less redness, oiliness, and dark pigmentation. Two caveats belong with it. The paper calls the trial double-blind, but the two materials look and feel different, so participants could plausibly tell which they had. And the UVB numbers often quoted from this study — 7.4% transmitted through the dressing against 38% through the tape — measure the material itself, not a skin outcome in patients.

Forty adults over 65 with severe chronic venous insufficiency put on compression stockings with and without a donning device, in randomized order. The share who managed it successfully rose from 73% without a device to 93% with one. Success was predicted by being able to reach the forefoot by hand and by grip strength. Patients also rated donning with a device as easier.
