Oxygen use has extended from inpatient to outpatient settings for patients with chronic pulmonary diseases and complications of hypoxaemia. This article presents an overview of oxygen devices (oxygen concentrators, compressed gas cylinders and liquid oxygen) and delivery systems (high- and low-flow). The indications, advantages and disadvantages of each device and delivery system are presented, aiming to offer updated knowledge to the multidisciplinary team members managing patients with respiratory failure, and therefore allowing appropriate selection of devices and delivery systems that are tailored to the needs of each patient.

Background:traumatic ankle joint osteochondral lesions and defects (OHLD) is frequent cause of OA, chronic pain and loss of joint function; results of traditional treatment strategy are often unsatisfyingObjectives:to develop treatment algorithm for OHLD based on evaluation of previously determined main prognostic factors.Methods:the analysis of long-term (36 ± 4.5 months) treatment results of 239 patients after traumatic ankle joint OHLD revealed the following factors with the greatest predictive value (defined by PC – prognostic coefficient) for good result of treatment (defined as AOFAS function score 75-100 points): age < 40 years (PC = 8.5); size of OHLD ≤ 1.0 cm2; volume ≤ 1.5 cm3(PC = 8.0); osteoarthritis stage ≤ II (PC = 7.2). Based on these factors, a step-by-step, discrete and alternative algorithm for the choice of treatment tactics was created. The algorithm includes use of arthroscopic or open debridement, abrasive chondroplasty, bone marrow regeneration stimulation (microfracturing or tunneling), mosaic osteochondroplasty, arthroplasty or arthrodesis, the use of cellular regenerative technologies (bone marrow cells, platelet riched plasma), and others. Patients of older age with advanced OA need complex, step up approach, surgical treatment combined with regenerative cell technologies. The effectiveness of the differentiated approach to treatment was studied in 72 patients with OHLD (main group) in comparing to 72 patients in whom traditional treatment approaches were used, based on the stage of injury according to the Berndt & Hardy classification (comparison group).Results:compared to the traditional approach, the developed algorithm and treatment system allowed to half terms of hospitalization, to reduce the intensity of pain syndrome (by NRS) and increase the functional activity (by AOFAS) by 25%. In 3 years after trauma good/excellent results of treatment demonstrated 86% patients of main group and 32,2% of patients from comparing group (p<0,05).Conclusion:implementation of the developed treatment algorithm increases the number of good and excellent long-term results by 2.6 times and reduces the number of complications and unsatisfactory results by 4.9 times.Disclosure of Interests:None declared

Objective The traditional treatment for patients with syndromic craniosynostosis and midfacial retrusion has consisted of Le Fort III osteotomy and advancement. Distraction with rigid external systems allows advancement of the midface segment much more than the conventional methods. This excessive advancement resulted in the superiormost margin of the advancement segment becoming prominent. It can be felt easily with palpation and may influence the appearance of the patient negatively. This article presents a procedure osteotomy designed to modify the osteotomy lines at the lateral orbital rims and smooth the step deformity at the lateral canthal region. Results The seesaw osteotomy produced a smooth contour at the lateral orbital rim. Planned advancement was achieved without difficulty and without adverse long-term effects.

Cancer is a major worldwide public health issue, responsible for millions of deaths every year. Cancer cases and deaths are expected to increase rapidly with population growth, age, and lifestyle behaviors that increase cancer risk. Long-term chemotherapy results in acquired drug resistance. Traditional treatment methods have limitations and cannot effectively treat distal metastatic cancers. Application of nanocarriers in multi-chemotherapy must be promoted. With research progress, the shortcomings of traditional nanocarriers have gradually become evident. Carrier-free nanodrugs with desirable bioactivity have attracted considerable attention. In this review, we provide an overview of recent reports on several carrier-free nanodrug delivery systems based on phytochemicals. This review focuses on the advantages of carrier-free nanodrugs, and provides new insights for establishment of ideal cancer treatment nanosystems.

For many years, the accepted wisdom among potato storage researchers and industry personnel linked the accumulation of CO2 in the storage atmosphere to darkening of potato fry color. Dark fry color is undesirable in the potato processing industry, as consumers prefer light-colored finished products. Previous research to elucidate the effect of CO2 has presented conflicting results. In three consecutive years of storage trials, the effects of elevated CO2 concentrations, reduced O2 concentrations and ethylene gas on the fry color and sugar content of `Russet Burbank' potato (Solanum tuberosum L.) tubers were evaluated. The potatoes were stored in modified atmosphere chambers and selected atmosphere mixtures were supplied from compressed gas cylinders. Four 3-week trials were conducted in 2002 and two 9-week trials were conducted in each of 2003 and 2004. Fry color and tuber sugars were assessed at the start of each trial and after several weeks of exposure to the treatment atmospheres. Compared with untreated controls, increased CO2 alone or in combination with decreased O2 had little or no effect on fry color or tuber sugars. During the second and third years, only selected treatments were repeated, with or without the addition of 0.5 μL·L–1 ethylene gas. Ethylene is known to affect potato fry color and reducing sugars. In three of four trials, tubers exposed to ethylene alone had darker fry color and higher reducing sugars compared with controls. Applied treatments had little or no effect on fry color and sugars in the fourth trial. Interestingly, in the same three of four trials, fry color of tubers exposed to both elevated CO2 and ethylene gas was not only darker than controls but also darker than tubers treated with ethylene alone. Similarly, reducing sugar concentrations were higher in tubers exposed to both ethylene and CO2 than with ethylene alone. No similar interaction between ethylene and oxygen concentration was observed. The results suggest a synergistic negative effect of trace ethylene and elevated CO2 on fry color, which may explain the apparently contradictory findings of some published research examining the effects of CO2 on potato fry color.
