Background. Infantile hemangiomas are revealed in 1-3% of newborns and 10-12% of infants. There are only anecdotal reports on the laser therapy efficacy in this pathology management. However, there is no common approach to the use of this method in the complex treatment of infantile hemangioma in infants. Clinical Cases Description. Two clinical cases of infantile hemangioma are presented. Patients underwent complex treatment: systemic propranolol and laser therapy via pulsed dye laser. Laser exposure modes ware selected individually: laser spot sizes were 10 and 12 mm, energy levels were 5-10 J/cm2, burst duration was short (0.45 ms) or long (10-20 ms), procedure duration was from 15 to 40 minutes, number of procedures varied from 1 to 8. Laser therapy has shown its efficacy in treatment of superficial infantile hemangioma. Conclusion. The indication for using laser therapy in management of infants with hemangiomas is especially persistent residual signs such as telangiectasias and erythema after spontaneous or drug involution phase. Laser therapy allows us to avoid aggressive methods and improves the quality of life of our patients according to this article.

Background. Acne scar formation is a common consequence of acne vulgaris, in most cases atrophic scars resulting from tissue loss caused by inflammation of the pilosebial units. Aims: To study the effectiveness of combined laser therapy with Nd:YAG laser and Er: YAG laser with autologous plasma with cells in patients with different phenotypes of post-acne atrophic scars. Materials and methods. Depending on the method of treatment of post-acne scars, the patients were divided into 2 groups: Group 1 (n=28) with ice pick scars 10 patients; boxcar 9 patients; rolling 9 patients and group 1 (n=30) among them with ice pick scars 10; boxcar 9; rolling 11 patients. In group 1A, phototherapy was performed using a combination of Nd:YAG laser and Er:YAG laser. Immediately after laser exposure, autologous plasma was applied to the skin of the face of group 1B patients. To assess the effectiveness, the Manchester scale of assessment of scar deformities was used. The effectiveness was also evaluated using the Global Aesthetic Scale (GAIS) on a 3-point system. In this study, cutometry and ultrasound were performed to assess the elasticity of the skin in the foci of atrophy. Results. The indicator "color" on the MSS scale improved in the 1st group by 54.8%, in the 2nd by 83.7%, the indicator "texture" by 57.1 and 78.1%, the indicator "relief" by 43.8 and 66.7%, the indicator "displacement" by 54.9 and 82.1%, respectively. There were no patients with a deterioration or lack of effect on the GAIS scale in any of the study groups. According to the ultrasound scan data, the greatest effectiveness was observed in the group of complex treatment . Conclusion. Complex treatment, including the use of combined laser therapy (erbium and neodymium lasers) and autologous plasma with cells, is a highly effective technique for the treatment of atrophic post-acne scars.

The objective of this study was to evaluate the effects of dietary energy levels on growth performance, rumen fermentation and bacterial community, and meat quality of Holstein-Friesians bulls slaughtered at different ages. Thirty-six Holstein-Friesians bulls (17 months of age) were divided into a 3 × 3 factorial experiment with three energy levels (LE, ME and HE; metabolizable energy is 10.12, 10.90 and 11.68 MJ/kg, respectively) of diets, and three slaughter ages (20, 23 and 26 months). Results indicated that bulls fed with ME and HE diets had higher dry matter intake, average daily gain, and dressing percentage at 23 or 26 months of age. The ME and HE diets also reduced bacterial diversity, altered relative abundances of bacteria and produced lower concentrations of acetate, but higher butyrate and valerate concentrations in rumen fluid. Increasing in dietary energy and slaughter age increased the intramuscular fat (IMF) and water holding capacity. In summary, Holstein-Friesians bulls fed with ME and HE diets, slaughtered at 23 and 26 months of age could be a good choice to produce beef with high IMF. Slaughter age may have less influence than dietary energy in altering fermentation by increasing amylolytic bacteria and decreasing cellulolytic bacteria, and thus, further affecting meat quality.

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Background In 2014, Siemens developed a new software-based scatter correction (Progressive Reconstruction Intelligently Minimizing Exposure [PRIME]), enabling grid-less digital mammography. Purpose To compare doses and image quality between PRIME (grid-less) and standard (with anti-scatter grid) modes. Material and Methods Contrast-to-noise ratio (CNR) was measured for various polymethylmethacrylate (PMMA) thicknesses and dose values provided by the mammograph were recorded. CDMAM phantom images were acquired for various PMMA thicknesses and inverse Image Quality Figure (IQFinv) was calculated. Values of incident entrance surface air kerma (ESAK) and average glandular dose (AGD) were obtained from the DICOM header for a total of 1088 pairs of clinical cases. Two experienced radiologists compared subjectively the image quality of a total of 149 pairs of clinical cases. Results CNR values were higher and doses were lower in PRIME mode for all thicknesses. IQFinv values in PRIME mode were lower for all thicknesses except for 40 mm of PMMA equivalent, in which IQFinv was slightly greater in PRIME mode. A mean reduction of 10% in ESAK and 12% in AGD in PRIME mode with respect to standard mode was obtained. The clinical image quality in PRIME and standard acquisitions resulted to be similar in most of the cases (84% for the first radiologist and 67% for the second one). Conclusion The use of PRIME software reduces, in average, the dose of radiation to the breast without affecting image quality. This reduction is greater for thinner and denser breasts.

Several studies on methane (CH4) emissions have focussed on selecting high and low CH4-emitting animals. One challenge faced by this work is the lack of consistency, or repeatability, in animal rankings over time. Repeatability for individual animals over time needs to be high to reliably detect high and low CH4-emitting animals. A possible explanation for the lack of repeatability is a relatively high within-animal variation in daily CH4 emissions, meaning that animals could then change their ranking when compared at different points in time. An experiment was undertaken with four non-lactating dairy cattle to assess the within- and between-animal variation in CH4 emissions over time when measured using the sulfur hexafluoride (SF6) tracer technique. Two contrasting diets were fed to the cattle at maintenance energy levels: lucerne silage (diet 1) and a cereal + lucerne + straw mixed ration diet (diet 2). Daily CH4 measurements were undertaken for 23 days on diet 1 and 30 days on diet 2. There was a significant (P < 0.001) difference between diet 1 and diet 2 in daily CH4 production, with mean (±s.e.) production of 124.3 (11.1) g CH4/day from diet 1 and 169.8 (±11.0) g CH4/day from diet 2. Lower CH4 yield (g CH4/kg dry matter intake) was recorded on diet 1 (22.8 ± 2.0) than diet 2 (32.0 ± 2.0). Cows differed significantly (P < 0.05) from one another in daily CH4 yield (diet 1: cow 1 = 19.4 ± 0.6, cow 2 = 22.2 ± 0.8, cow 3 = 23.2 ± 0.7, cow 4 = 25.4 ± 0.6; diet 2: cow 1 = 26.0 ± 0.7, cow 2 = 36.4 ± 0.7, cow 3 = 29.3 ± 0.7, cow 4 = 36.6 ± 0.7). Variances for daily CH4 yield were smaller for diet 1 (within animal = 6.91, between animals = 6.23) than for diet 2 (within animal = 10.09, between animals = 27.79). Estimates of repeatability (variation between animals/total variation) for daily CH4 yield were 47 and 73% in diet 1 and 2, respectively. Coefficients of variation in average daily CH4 emissions in this experiment ranged from 8 to 18% despite the fact that each animal received the same quantity and quality of feed each day. While further research is required, the high within-animal variability in CH4 emissions measured using the SF6 tracer technique may explain why there has been difficulty in obtaining consistent rankings in CH4 yields when animals are measured on multiple occasions. The results also suggest that the SF6 tracer technique may exaggerate apparent between animal differences in CH4 emissions.

e24031 Background: Plinabulin is a novel non-G-CSF small molecule being developed for the prevention of chemotherapy in conjunction with pegfilgrastim and is administered via 30 min IV infusion, 30 min after chemo on Day (D) 1. The QoL was analyzed using the Functional Assessment of Cancer Therapy - General questionnaire (FACT-G) as part of a phase 3 (Ph3) clinical trial comparing pegfilgrastim alone versus pegfilgrastim and plinabulin for the prevention of neutropenia in newly diagnosed breast cancer patients being treated with Docetaxel (75 mg/m2), Doxorubicin (50 mg/m2), and Cyclophosphamide (500 mg/m2) (TAC) on D1 for four 21 D cycles and study treatment. Methods: The FACT-G was administered to patients in China and Ukraine using an ePRO app downloaded onto patients' phones as part of the Phase 3 PROTECTIVE-2 trial (NCT0329457) with TAC. Patients completed the FACT-G during each chemo cycle at D-1, D1, D8 and D15. Patients received reminders 1 hour before the required completion time and all entries were time stamped. The FACT-G measured the impact of cancer on four categories: Physical wellbeing, Social wellbeing, Emotional wellbeing and Functional wellbeing. Results: Compared to pegfilgrastim alone, patients on plinabulin + pegfilgrastim performed significantly better for Physical wellbeing on D8 and D15 of Cycle 2 (p < 0.0589 and p < 0.0039 respectively) and Cycle 3 (p < 0.0360 and p < 0.0343 respectively). Further analysis of the sub questions showed that both energy levels “I have a lack of energy” and pain”(I have pain” were significantly better for the plinabulin + pegfilgrastim combination versus pegfilgrastim alone (p < 0.0377 and p < 0.0420 respectively). Overall FACT-G completion compliance for the trial was 91%. Conclusions: The Physical wellbeing (in particular, pain and for energy levels) of patients receiving plinabulin in combination with pegfilgrastim for the prevention of TAC CIN, was significantly less impacted by chemo dosing compared to the pegfilgrastim alone arm. In addition, the results suggest that patients receiving the combination therapy recovered their pre-chemo Physical wellbeing levels more rapidly. Clinical trial information: NCT03531099.

Современные подходы к организации диагностики и лечения больных пожилого и старческого возраста со злокачественными новообразованиями позволяют улучшать качество жизни и увеличивать продолжительность жизни. Оценка гериатрического статуса в онкологии позволяет прогнозировать осложнения в процессе комплексного лечения, в том числе лекарственного, модифицировать терапию для уменьшения факторов риска неблагоприятных исходов, осуществлять отбор пациентов на специализированное лечение с использованием стандартных схем. Таким образом, своевременная оценка гериатрических синдромов и их коррекция способна расширить показания к специализированному лечению больных пожилого и старческого возраста. Modern approaches to the organization of diagnosis and treatment of elderly and senile patients with malignant tumors allow to maintain the necessary level of health, improve the quality of life and increase life expectancy. Assessment of geriatric status in Oncology allows: to predict complications during the complex treatment, including drug treatment; to modify treatment to reduce the risk factors of adverse outcomes; to select patients for specialized treatment using standard schemes. So, timely assessment of geriatric syndromes and their correction can expand the indications for specialized treatment of elderly and senile patients.

This study was carried out to evaluate the energy levels in the diet to obtain better performance rates and quality of eggs from laying hens in the second production cycle. One hundred and eighty Bovans Goldline laying hens with 62 weeks of age were used during four 28-day periods. A completely randomized experimental design was used with four metabolizable energy levels (2,650, 2,725, 2,800, 2,875 and 2,950 kcal/kg), each with six replicates of six birds. The energy level of diet did not affect the weight of the egg, yolk, albumen and eggshell, the percentages of yolk, albumen and eggshell, yolk color and egg specific gravity. Feed intake, egg production, egg mass and feed conversion per egg mass and per dozen eggs increased significantly with increasing levels of metabolizable energy. Feed intake decreased linearly as the energy level in the diet increased. The metabolizable energy levels showed a quadratic effect on egg production, egg mass and feed conversion per egg mass and per dozen eggs. The metabolizable energy level of 2,830 kcal/kg was the most appropriate to promote better performance and quality of eggs from laying hens in the second production cycle.
