Brachytherapy (BT) plays a key role in cancer treatment by delivering a high dose to a small volume over a short time. The use of BT is currently validated in a wide range of cancers such as cervical, prostate and breast cancers while being a favourable choice for organ preservation, such as in penile or rectal cancer, or in the setting of reirradiation. Consideration of the radiobiology of BT is integral to the choices made around dose and fractionation and combination with other techniques such as external beam radiotherapy (EBRT).

Article Synopsis
  • Platelet transfusions are given to preterm infants to prevent bleeding, but recent studies showed higher risks of mortality and major bleeding with transfusions at a higher platelet count threshold of 50 × 10/L compared to 25 × 10/L.
  • A prospective observational study across 64 neonatal intensive care units in 22 European countries was conducted to assess current platelet transfusion practices, which included tracking transfusion rates, indications, and patient outcomes.
  • The findings indicated that the lower transfusion threshold of 25 × 10/L is being adopted in practice, though there's considerable variation in transfusion volumes and rates, highlighting the need for further research to optimize these practices.

Coronavirus disease 2019 (COVID-19) has been associated with various systemic complications, including potential impacts on ocular health. Recent studies have suggested that COVID-19 may lead to changes in retinal structure, particularly in the neuroretinal and retinal nerve fiber layers (RNFL). This study aimed to examine changes in neuroretinal and RNFL of the optic dics based on optical coherence tomography (OCT) in patients hospitalized due to COVID-19 bilateral pneumonia at 2 time points after discharge.

Background: Abortion is one of the most common medical procedures worldwide. Despite this, access to abortion on demand remains restricted in many countries, including Poland. As a result, many women resort to undergoing the procedure without medical supervision, putting themselves at risk of serious health consequences such as drug poisoning, excessive bleeding, and hypovolemia.

Article Synopsis
  • The study investigates how glucose transporter proteins (GLUTs) in the placenta are expressed in pregnant women with type 1 diabetes, early gestational diabetes (eGDM), and healthy controls, aiming to find correlations with clinical parameters.
  • Significant decreases in GLUT-3 and GLUT-4 mRNA expression were observed in patients with diabetes, especially eGDM, and these changes were linked to lower neonatal birth weights and various glycemic factors.
  • The research also uncovered substantial transcriptomic changes in women with diabetes, indicating a complex relationship between GLUT expression, neonatal outcomes, and glycemic control.

ADAR1 expression in different cancer cell lines and its change under heat shock.

J Appl Genet

Department of Biochemistry and Molecular Biology, Poznan University of Medical Sciences, Święcickiego 6 Street, 60-781, Poznań, Poland.

Adenosine deaminase acting on RNA 1 (ADAR1) plays an essential role in the development of malignancies by modifying the expression of different oncogenes. ADAR1 presents three distinct activities: adenosine-to-inosine RNA editing, modulating IFN pathways, and response to cellular stress factors. Following stressors such as heat shock, ADAR1p110 isoform relocates from the nucleus to the cytoplasm, where it suppresses RNA degradation which leads to the arrest of apoptosis and cell survival.

Circuit training is a form of body conditioning with endurance and resistance components. Given the function of skeletal muscle as an endocrine organ secreting various myokines involved in maintaining glucose metabolism homeostasis, our study focused on estimating the impact of the implemented training program on the direction of changes in myokines such as interleukin (IL)-6, IL-10, fibroblast growth factor 21 (FGF21), and irisin in women newly diagnosed with insulin resistance. This prospective controlled trial randomly divided 42 women into two groups.

  • The bronchopleural fistula (BPF) is a serious complication that can occur after pneumonectomy, often addressed through various surgical buttressing techniques to improve healing.
  • A review of literature on this topic included 27 articles, but only 16 were suitable for analysis due to factors like small sample sizes and irrelevant surgical procedures.
  • The results indicated that three studies found significant benefits of using bronchial stump buttressing to reduce BPF risk, while the rest provided descriptive statistics or assessed blood perfusion in the tissue used.

Article Synopsis
  • - Cell senescence starts as a protective mechanism against tumors but can eventually lead to cancer recurrence and damage to surrounding tissues due to the buildup of senescent cells.
  • - Senescent cells release bioactive molecules known as the senescence-associated secretory phenotype (SASP), which can cause chronic inflammation and promote tumor growth through signaling to nearby cells.
  • - Senolytic drugs target and remove senescent cells, potentially enhancing cancer treatments by preventing tumor recurrence and allowing safer, lower doses of chemotherapy or radiotherapy, making them a promising option in personalized cancer therapy.

Conventional repair of rotator cuff tears bears a variable but significant risk of incomplete healing. Biological therapies that accompany surgical rotator cuff repair include platelet-rich plasma, stem cells of different origins, and biological scaffolds. Biological therapies facilitate the regeneration of the correct microarchitecture of the tendon attachment to the bone and reduce failures after surgical rotator cuff repair.
