OS production, mitochondrial apoptosis and, finally, changes or damage to erythrocytes.

Myocardial ischemia-reperfusion (I/R) injury is still thought to be an unsolved puzzle that may lead to reperfusion arrhythmias and sudden cardiac death. Inflammation plays a key role in myocardial I/R. Studies have indicated that purinoceptor 2Y12 (P2Y12) antagonists have anti-inflammatory properties that are cardioprotective.

In this study, we explored whether inhibition of P2Y12 in macrophages could reduce cardiac inflammation and attenuate reperfusion arrhythmias after myocardial I/R.

Rats were randomly divided into 4 groups group A (control + vehicle); group B (control + P2Y12 shRNA lentiviral vector); group C (myocardial I/R + vehicle); and group D (myocardial I/R + P2Y12 shRNA lentiviral vector). Infarct size, reperfusion arrhythmias, and P2Y12 and platelet endothelial cell adhesion molecule-1 (CD31) protein expression were measured.

The incidence of reperfusion ventricular tachycardia and fibrillation (VT/VF) was 90% in the I/R group, while it was reduced to 50% by P2Y12 shRNA treatment. Ionized calcium binding adapter molecule 1 and P2Y12 immunoreactivity in the myocardial I/R + P2Y12 shRNA group was lower compared to the myocardial I/R group. P2Y12 shRNA treatment increased α-smooth muscle actin (α-SMA) and CD31 protein expression, as evidence by western blot and immunohistochemistry analyses (0.31 ±0.01 compared to 0.26 ±0.008, group D compared to group C, p < 0.05).

Inhibition of P2Y12 in macrophages improved reperfusion arrhythmias in our rat I/R model, suggesting that blocking P2Y12 could decrease the inflammatory response after cardiac perfusion.

Interleukin 6 (IL-6) is a cytokine involved in inflammation, infection response and also regulation of metabolism. It stimulates target cells through a membrane-bound IL-6 receptor. Inflammatory bowel diseases (IBD) are autoimmune diseases whose incidence and prevalence are increasing worldwide. It is a group of chronic gastrointestinal disorders characterized by multifactorial, still unknown pathogenesis, varied symptomatology, course with periods of exacerbation and remission, and polymorphic infiltration in histopathological examination. As it is known, pro-inflammatory cytokines, including IL-6, in IBD initiate, intensify and support the development of the inflammatory process in the intestine. Our knowledge of IL-6 biology has important consequences for therapeutic strategies. Elevation of IL-6 concentration can be considered as an early and sensitive, although non-specific marker for various inflammatory conditions and may be used in the diagnosis and monitoring of patients with IBD.

Anterior cruciate ligament (ACL) reconstruction is the prevailing procedure in cases of ACL rupture.

To assess the long-term safety of implementing a synthetic ligament with the Ligament Advanced Reinforcement System (LARS) in primary reconstruction of the ACL.

The retrospective analysis involved 403 patients who had undergone ACL reconstruction with the same results in clinical and functional assessments. The patients comprised 2 groups. In group I, a LARS graft was implemented, while in group II, an autograft was used. The Lachman test, anterior drawer test, pivot-shift test, Lysholm scale, IKDC 2000, pain posited to be experienced, the possibility of postoperative complications, the time required to return to work, and revision surgery were all considered and analyzed.

The visual analogue scale (VAS) pain score in group I ranged from 37.34 ±8.22 mm on day 3 to 17.21 ±5.45 mm on day 28. In group II, it ranged from 64.72 ±10.20 mm on day 3 (p < 0.05) to 18.67 ±6.57 mm on day 28. The period of time taken to return to office work in group I was 7.04 ±1.82 weeks, and 9.21 ±1.75 weeks in group II (p < 0.05). The time taken to return to physical work in group I was 20.50 ±2.91 weeks, and 21.12 ±3.12 weeks in group II. Postoperative scar and local complications were statistically less prominent in group I. The cost and number of revision surgeries were greater in the first group.

Reconstruction of the ACL using a synthetic graft such as LARS yields similar results to an autograft in a cohort follow-up. find more Long-term results show a large number of revision surgeries when LARS is used. This method should be used with caution.

As much as 90-95% of constipation cases have a functional basis, and although the pathogenesis of functional constipation remains unclear, its etiology is considered to be multifactorial. Its growing prevalence has been attributed to the occurrence of disorders in the homeostasis of gastrointestinal microbiota. In humans, the best known microbiome is that of the intestines, which has been the subject of a number of studies based on recognition of the 16S rRNA gene sequence. Microbiota are believed to influence the pathogenesis of functional constipation by affecting peristalsis, relationship with diet, and physical activity. The paper evaluates the role of intestinal microbiota in functional constipation and describes its contribution to the onset of disease. Determining the importance of the microbiome in the pathogenesis of functional constipation creates hope for the development of new prevention and treatment methods.

Fabry disease (FD) is an X-linked disorder related to a deficiency of the lysosomal enzyme alpha-galactosidase A. In Poland, enzyme replacement therapy (ERT) for FD is offered by the National Health Fund only at selected hospital infusion centers. Patients with FB are considered at a high risk of developing complications from COVID-19. Some patients omitted infusions due to fear of infection or outbreaks in hospitals. Lack of alternative infusion sites hampered the situation.

To analyze the impact of the SARS-CoV-2 pandemic on FD patients, especially their fears and expectations, the Polish FD Collaborative Group collaborated on a survey project.

Between September and November 2020, we distributed a customized survey exploring expectations and fears among FD subjects.

Fifty-five individuals (35 receiving ongoing ERT) from different FD centers completed the study. The median age was 40 years [IQR 25; 50], and gender distribution was almost equal (27 F; 28 M). One-fourth of FD patients reported severe disability limiting transportation for infusions that, in the opinion of the other 25% of responders, consumed >4 h.
