Introduction: Patients implanted with a range-of-vision intraocular lens (IOL) (multifocal or extended depth of focus, EDOF) may be more susceptible to visual disturbances from poor tear film quality, and prophylactic treatment of meibomian gland dysfunction (MGD) has been recommended. The purpose was to evaluate whether vectored thermal pulsation (LipiFlow™) treatment prior to cataract surgery with a range-of-vision IOL safely improves postoperative outcomes.
Methods: This is a prospective, randomized, open-label, crossover, multicenter study of patients with mild-to-moderate MGD and cataract. The test group underwent LipiFlow treatment prior to cataract surgery and implantation of an EDOF IOL, while the control group did not. Both groups were evaluated 3 months postoperatively, after which the control group received LipiFlow treatment (crossover). The control group was re-evaluated 4 months postoperatively.
Results: A total of 121 subjects were randomized, with 117 eyes in the test group and 115 eyes in the control group. At 3 months after surgery, the test group had a significantly greater improvement from baseline in total meibomian gland score compared with the control group (P = 0.046). At 1 month after surgery, the test group had a significant decrease in corneal (P = 0.04) and conjunctival (P = 0.002) staining compared to the control group. At 3 months after surgery, the test group had significantly lower incidence of being bothered by halos compared with the control group (P = 0.019). The control group had a significantly lower incidence of being bothered by multiple or double vision compared with the test group (P = 0.016). After crossover, patients had significant improvement in vision (P = 0.03) and total meibomian gland score (P < 0.0001). No safety concerns or relevant safety findings were uncovered.
Conclusion: Presurgical LipiFlow treatment of patients implanted with range-of-vision IOLs improved meibomian gland function and postoperative ocular surface health. This supports guidelines recommending proactive diagnosis and management of MGD in patients with cataracts to improve patient experience.

Background: To investigate the effect of Midnight-noon Ebb-flow combined with five-element music therapy in the continuous nursing of patients with chronic wounds.
Methods: From March 2022 to November 2023, we recruited 50 eligible chronic wound patients and randomly divided them into two groups according to a random number table: the experimental group (n = 25) and the control group (n = 25). The control group was treated with conventional nursing measures.
Effect of exercise training on modulating the TH17/TREG imbalance in individuals with severe COPD: A randomized controlled trial.

Laboratory of Experimental Therapeutics, LIM-20, Department of Clinical Medicine, School of Medicine, University of Sao Paulo, Sao Paulo, Brazil.
Background: Chronic obstructive pulmonary disease (COPD) induces an imbalance in T helper (Th) 17/regulatory T (Treg) cells that contributes to of the dysregulation of inflammation. Exercise training can modulate the immune response in healthy subjects.
Objective: We aimed to evaluate the effects of exercise training on Th17/Treg responses and the differentiation of Treg phenotypes in individuals with COPD.

We aimed to determine the persisting effects of various exercise modalities and intensities on functional capacity after periods of training cessation in older adults. A comprehensive search was conducted across the Cochrane Library, PubMed/MEDLINE, Scopus, and Web of Science Core Collection up to March 2024 for randomized controlled trials examining residual effects of physical exercise on functional capacity in older adults ≥ 60 years. The analysis encompassed 15 studies and 21 intervention arms, involving 787 participants.

Rationale: Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.
Aims And Objectives: Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.
