Total surgical time in laparoscopic supracervical hysterectomy with laparoscopic in-bag-morcellation compared to laparoscopic supracervical hysterectomy with uncontained morcellation.

Facts Views Vis Obgyn 2022 Mar;14(1):59-68

Background: A possible solution to the problem of cell dissemination through laparoscopic uncontained morcellation during laparoscopic supracervical hysterectomy (LASH) is the use of laparoscopic in-bag morcellation. One criticism regarding the use of in-bag morcellation is the additional surgical time associated with this procedure.

Objectives: In this retrospective study we compared the total surgical time in LASH with laparoscopic in-bag morcellation (107 cases from 2016-2018) and LASH with uncontained morcellation (47 cases from 2015-2017). Read More

Inhibition of STAT6 Activation by AS1517499 Inhibits Expression and Activity of PPARγ in Macrophages to Resolve Acute Inflammation in Mice.

Biomolecules 2022 03 14;12(3). Epub 2022 Mar 14.

Department of Physiology, College of Medicine, Ewha Womans University, Seoul 07804, Korea.

Signal transducer and activator of transcription 6 (STAT6) promotes an anti-inflammatory process by inducing the development of M2 macrophages. We investigated whether modulating STAT6 activity in macrophages using AS1517499, the specific STAT6 inhibitor, affects the restoration of homeostasis after an inflammatory insult by regulating PPARγ expression and activity. Administration of AS1517499 suppressed the enhanced STAT6 phosphorylation and nuclear translocation observed in peritoneal macrophages after zymosan injection. Read More

Successful recovery of severe hypothermia with minimally invasive central catheter.

Am J Emerg Med 2022 Jun 10;56:393.e1-393.e4. Epub 2022 Mar 10.

Emergency Department, Medical Director, Kettering Health Hamilton, United States of America.

Background: Severe hypothermia can result in malignant arrhythmias or cardiac arrest and require invasive central rewarming modalities due to a core body temperature < 28 °C. Difficult rescue missions can make continuous CPR challenging, but the decrease in oxygen consumption at these low temperatures allows for successful recovery despite the delay. Although other active warming techniques, such as peritoneal lavage, intravascular warming catheter, and renal replacement therapy can be beneficial, the consensus statements recommend extracorporeal life support as the preferred rewarming method.

Cromolyn Sodium differentially regulates human mast cell and mouse leukocyte responses to control allergic inflammation.

Pharmacol Res 2022 04 9;178:106172. Epub 2022 Mar 9.

Pharmacology and Experimental Therapeutics Unit, School of Pharmacy, Institute for Drug Research, Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel. Electronic address:

Background: Cromolyn Sodium (CS) has been used in the past as an anti-allergy drug owing to its mast cell (MC) stabilizing properties that impair histamine release. However, additional mechanisms for its clinical actions are likely and might help to identify new roles for MCs and leukocytes in regulating inflammation. Here, using human cord blood-derived MCs (CBMCs), mouse bone marrow-derived MCs (BMMCs) and eosinophils (BMEos), and in vivo mouse models of allergic inflammation (AI), additional actions of CS on MCs were determined.

Irrigation of peritoneal cavity with cold atmospheric plasma treated solution effectively reduces microbial load in rat acute peritonitis model.

Sci Rep 2022 03 7;12(1):3646. Epub 2022 Mar 7.

Department of Pediatric Surgery, School of Medicine, Izmir Katip Çelebi University, Izmir, 35620, Turkey.

Accurate and timely diagnosis of appendicitis in children can be challenging, which leads to delayed admittance or misdiagnosis that may cause perforation. Surgical management involves the elimination of the focus (appendectomy) and the reduction of the contamination with peritoneal irrigation to prevent sepsis. However, the validity of conventional irrigation methods is being debated, and novel methods are needed. Read More
