Bone marrow stimulation in arthroscopic rotator cuff repair is a cost-effective and straightforward technique to reduce retear rates: A systematic review and meta-analysis
Authors: Zhang Lei , Zhu Yanlin , Xu Tianhao , Fu Weili 
Published: February 2023

BackgroundBone marrow stimulation (BMS) has been considered a well-established method for treating knee and ankle osteochondral lesions. Some studies have also shown that BMS can promote healing of the repaired tendon and enhance biomechanical properties during rotator cuff repair. Our purpose was to compare the clinical outcomes of arthroscopic repair rotator cuff (ARCR) with and without BMS.MethodsA systematic review with meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed, Embase, Web of Science, Google scholar, ScienceDirect, and the Cochrane Library were searched from inception to March 20, 2022. Data on retear rates, shoulder functional outcomes, visual analog score and range of motion were pooled and analyzed. Dichotomous variables were presented as odds ratios (OR), and continuous variables were presented as mean differences (MD). Meta-analyses were conducted with Review Manager 5.3.ResultsEight studies involving 674 patients were included, with mean follow-up period ranging from 12 to 36.8 months. Compared to ARCR alone, the intraoperative combination of the BMS resulted in lower retear rates (P &lt; 0.0001), but showed similar results in Constant score (P = 0.10), University of California at Los Angeles (UCLA) score (P = 0.57), American Shoulder and Elbow Surgeons (ASES) score (P = 0.23), Disabilities of the Arm, Shoulder and Hand (DASH) score (P = 0.31), VAS (visual analog score) score (P = 0.34), and range of motion (ROM) (forward flexion, P = 0.42; external rotation, P = 0.21). After sensitivity analyses and subgroup analyses, no significant changes in statistical results were observed.ConclusionCompared to ARCR alone, the combination of intraoperative BMS can significantly reduce the retear rates, but showed similar short-term results in functional outcomes, ROM and pain. Better clinical outcomes are anticipated in the BMS group by improving structural integrity during long-term follow-up. Currently, BMS may be a viable option in ARCR based on its straightforward and cost-effective advantages.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier: CRD42022323379.
Basic Principles of Managing Oncological Patients with Chronic Coronary Syndromes
Authors: Суджаева О.А. 
Published: February 2023

В статье представлена часть обзора Рекомендаций Европейского общества кардиологов по кардиоонкологии (2022), посвященная ведению пациентов с хроническими коронарными синдромами (ХКС). На разных этапах лечения рака (при постановке диагноза, проведении специализированного лечения и в разные сроки после него) ведение пациентов с ХКС имеет ряд особенностей. Следует учитывать повышенный риск развития кардиологических осложнений у пациентов с ХКС и онкологией на всех этапах лечения и динамического наблюдения за выжившими после рака, в том числе получивших лечение в детском возрасте. Немаловажной частью ведения данной категории пациентов является оценка лекарственного взаимодействия между основными антиангинальными препаратами и средствами, используемыми для лечения рака. Ведение онкологических пациентов с ХКС зачастую требует мультидисциплинарного подхода с привлечением врачей-специалистов онкологов, химиотерапевтов, интервенционных кардиологов, кардиохирургов и клинических фармакологов. Указанные аспекты нашли отражение в настоящей статье.
The article presents a part of the review of the European Society of Cardiology Guidelines for Cardio-Oncology (2022) on the management of patients with chronic coronary syndromes (CCS). At different stages of cancer treatment (during diagnosis, specialized treatment and at different times thereafter), the management of patients with CCS has a number of special features. The increased risk of developing cardiac complications in patients with CCS and oncology should be taken into account at all stages of treatment and dynamic monitoring of cancer survivors, even those who received treatment in childhood. An important part of the management of this category of patients is the assessment of drug interactions between the main antianginal drugs and drugs used to treat cancer. The management of cancer patients with CCS often requires a multidisciplinary approach involving medical specialists: oncologists, chemotherapists, interventional cardiologists, cardiac surgeons, and clinical pharmacologists. These aspects are reflected in this article.
"Arrhythmic" Mitral Valve Prolapse
Authors: Трисветова Е.Л. , Ушакова Л.Ю. 
Published: February 2023

Пролапс митрального клапана описан в 70-х годах прошлого века как доброкачественное заболевание, вместе с тем в последующие годы исследователи сообщали о случаях желудочковых нарушений ритма сердца и внезапной сердечной смерти у пациентов с пролабированием створок митрального клапана. В настоящее время описан фенотип «аритмического», или «злокачественного», пролапса митрального клапана с характерными демографическими, электрокардиографическими и выявленными при визуализации сердца признаками. «Аритмический» пролапс митрального клапана часто возникает у женщин молодого возраста с нарушениями реполяризации на электрокардиограмме, с дизъюнкцией и систолическим скручиванием (curling) митрального кольца, фиброзом папиллярных мышц и задне- или нижнебазальной стенки левого желудочка, являющихся морфологическим субстратом желудочковых аритмий. Среди патофизиологических механизмов, обусловливающих появление электрической нестабильности сердца, выделяют вызванные механическим стрессом изменения рефрактерных периодов желудочков, электрофизиологические изменения в волокнах Пуркинье, гипермобильность фиброзного кольца и аномальную тракцию папиллярных мышц. Знание о факторах риска развития жизнеугрожающих аритмий и внезапной сердечной смерти и их своевременное выявление позволит выбрать эффективные методы лечения и улучшить прогноз пациентов с «аритмическим» пролапсом митрального клапана.
Mitral valve prolapse was described in the 1970s as a benign disease, however, in subsequent years researchers reported cases of ventricular arrhythmias and sudden cardiac death in patients with mitral valve prolapse. A phenotype of "arrhythmic" or "malignant" mitral valve prolapse has now been described, with characteristic demographic, electrocardiographic, and cardiac imaging features. "Arrhythmic" mitral valve prolapse often occurs in young women with repolarization disorders on the electrocardiogram, with disjunction and systolic "curling" (twisting) of the mitral ring, fibrosis of the papillary muscles and the posterior or inferior basal wall of the left ventricle, which are the morphological substrate of ventricular arrhythmias. Among pathophysiological mechanisms responsible for electrical instability in the heart are mechanical stress-induced changes in ventricular refractory periods, electrophysiological changes in Purkinje fibers, hypermobility of the fibrous ring and abnormal traction of papillary muscles. Awareness of risk factors for life-threatening arrhythmias and sudden cardiac death and their timely detection should allow choosing effective treatment methods and improving the prognosis for patients with "arrhythmic" mitral valve prolapse.

Online learning and face-to-face learning are combined for today's learning which is also known as mixed learning. Mixed learning as a solution during a pandemic in learning activities. In the process of learning biology, motivation is needed to achieve learning objectives. Learning motivation is influenced by several factors, one of which is students' perceptions of the learning mix. The purpose of this study was to determine the relationship between students' perceptions of mixed learning and students' learning motivation in biology subjects. This research uses a correlational study method. The population of this research is the students of SMA Negeri 54 Jakarta with a total sample of 114 students of class X MIPA who were selected through the Simple Random Sampling. The results of the study revealed that there was a positive relationship between students' perceptions of mixed learning and students' learning motivation in biology subjects. The level of relationship is included in the moderate criteria, therefore, to increase student learning motivation not only by increasing student perceptions but many other factors that influence, because learning motivation can arise from within the individual (intrinsic) and from outside the individual (extrinsic).
