Role of Hyperbaric Oxygenation Plus Hypofractionated Stereotactic Radiotherapy in Recurrent High-Grade Glioma.

Front Oncol 2021 30;11:643469. Epub 2021 Mar 30.

Radiotherapy Unit, IRCCS Istituto Romagnolo per lo Studio dei Tumori (IRST) "Dino Amadori", Meldola, Italy.

Background: The presence of hypoxic cells in high-grade glioma (HGG) is one of major reasons for failure of local tumour control with radiotherapy (RT). The use of hyperbaric oxygen therapy (HBO) could help to overcome the problem of oxygen deficiency in poorly oxygenated regions of the tumour. We propose an innovative approach to improve the efficacy of hypofractionated stereotactic radiotherapy (HSRT) after HBO (HBO-RT) for the treatment of recurrent HGG (rHGG) and herein report the results of an analysis.

Neonatal outcomes and risk of neonatal sepsis in an expectantly managed cohort of late preterm prelabor rupture of membranes.

Eur J Obstet Gynecol Reprod Biol 2021 Apr 1;261:1-6. Epub 2021 Apr 1.

Obstetrics and Gynecology, University of Milano-Bicocca, FMBBM Monza, Carate Hospital, Lecco Hospital, Italy.

Objective: Expectant management in patients with prelabor preterm rupture of membranes between between 34 and 36 weeks (late preterm pPROM or LpPROM) has been shown to decrease the burden of prematurity, when compared to immediate delivery. As the severity of prematurity depends on gestational age (GA) at PROM, and PROM to delivery interval, we first investigated how such variables affect neonatal outcomes (NO). Second, we assessed the risk of neonatal sepsis. Read More

Large-Scale Screening of Lipase Acid Deficiency in at Risk Population.

Clin Chim Acta 2021 Apr 12. Epub 2021 Apr 12.

Normandie Univ, UNIROUEN, INSERM U1245, CHU Rouen, Department of Metabolic Biochemistry, 76000 Rouen, France. Electronic address:

Background: Lysosomal acid lipase deficiency (LALD, OMIM#278000) is a rare lysosomal disorder with an autosomal recessive inheritance. The main clinical manifestations are related to a progressive accumulation of cholesteryl esters, triglycerides or both within the lysosome in different organs such as the liver, spleen, and cardiovascular system. A wide range of clinical severity is associated with LALD including a severe very rare antenatal/neonatal/infantile phenotype named Wolman disease and a late-onset form named cholesteryl ester storage disease (CESD).

Effect of Implementation of HEART Chest Pain Protocol on Emergency Department Disposition, Testing and Cost.

West J Emerg Med 2021 Feb 4;22(2):308-318. Epub 2021 Feb 4.

Naval Medical Center Portsmouth, Department of Emergency Department, Portsmouth, Virginia.

Background: Symptoms concerning for acute coronary syndromes (ACS) such as chest pain and dyspnea are some of the most common reasons for presenting to an emergency department (ED). The HEART score (history, electrocardiogram, age, risk factors and troponin) was developed and has been externally validated in an emergency setting to determine which patients with chest pain are at increased risk for poor outcomes. Our hospital adopted a HEART score-based protocol in late 2015 to facilitate the management and disposition of these patients. Read More

Fetal Heart Rate Decelerations in Women with Sleep-Disordered Breathing.

Reprod Sci 2021 Apr 13. Epub 2021 Apr 13.

Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, University of Michigan, Ann Arbor, MI, USA.

Emerging literature has shown that women with sleep-disordered breathing (SDB) have increased risk for gestational hypertension/preeclampsia and gestational diabetes. Case reports suggest an association between maternal apnea and fetal heart rate deceleration but data are lacking on how maternal sleep impacts fetal health. Since decelerations may be associated with adverse outcomes, we sought to determine whether fetal heart rate decelerations were associated with SDB. Read More

Mechanical unloading by miniature axial flow pumps in late cardiac allograft failure due to acute rejection.

J Artif Organs 2021 Apr 12. Epub 2021 Apr 12.

Department of Cardiothoracic and Vascular Surgery, German Heart Center Berlin, Augustenburger Platz 1, 13353, Berlin, Germany.

Allograft failure secondary to rejection commonly requires a multimodal treatment, ultimately including mechanical circulatory support. A few case reports have demonstrated the use of Impella-devices due to its assumed favorable safety profile in this fragile cohort. However, this treatment option does not play a role in choice of anti-rejective therapy in clinical routine up to date. Read More

Permanent endoscopic gallbladder stenting versus removal of gallbladder drainage, Long-term outcomes after management of acute cholecystitis in high-risk surgical patients for cholecystectomy: Multi-center retrospective cohort study.

J Hepatobiliary Pancreat Sci 2021 Apr 12. Epub 2021 Apr 12.

First Department of Internal Medicine, Gifu University Hospital, Gifu, Japan.

Endoscopic transpapillary gallbladder drainage (EGBD) has been reported as an effective gallbladder drainage treatment option for acute cholecystitis in high-risk surgical patients. However, the long-term outcomes such as cholecystitis' recurrence rate after placement of EGB stenting (EGBS) have not been well studied yet.

Aims: The aim of the present study was to compare the long-term outcome of EGBS and removal of gallbladder drainage after percutaneous transhepatic gallbladder drainage (PTGBD) or endoscopic nasogallbladder drainage (ENGBD) for acute cholecystitis in high-risk surgical patients and clarify the usefulness of long-term placement of EGBS.

Division of Neurology, 6567Children's Hospital of Philadelphia, Philadelphia, PA, USA.

Mutations in are associated with a spectrum of neurologic disorders categorized as -related leukoencephalopathy. Affected children can present with global developmental delay or normal early development, followed by a variable loss of skills over time. Further research is needed to characterize the factors associated with the divergent developmental trajectories in this rare monogenic disorder because this phenotypic spectrum is not fully explained by genotype alone.

The Evolving Immunotherapy Landscape and the Epidemiology, Diagnosis, and Management of Cardiotoxicity: Primer.

JACC CardioOncol 2021 Mar 12;3(1):35-47. Epub 2021 Jan 12.

Cardiovascular Imaging Research Center (CIRC), Department of Radiology and Division of Cardiology, Massachusetts General Hospital, Boston, Massachusetts, USA.

Immune checkpoint inhibitors (ICIs) are newer therapies being applied to an increasing number of patients with cancer. Data suggest that up to 36% of cancer patients may be eligible for immunotherapy and, in late 2019, there were more than 3,362 clinical trials initiated to evaluate the effectiveness of immunotherapy, either as single agents or in combination with other immunotherapy, targeted therapies, or traditional cytotoxic or radiation therapy. With the combination of both immune and non-immune treatment approaches, the complexity in making the diagnosis of cardiotoxicity related to an ICI will increase substantially. Read More

A long-term follow-up study of minimally invasive Ivor Lewis esophagectomy with linear stapled anastomosis.

Surg Endosc 2021 Apr 9. Epub 2021 Apr 9.

Department of Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Background: Minimally invasive esophagectomy (MIE) is increasingly performed to expect lower complication rate compared to open esophagectomy. Studies of minimally invasive Ivor Lewis esophagectomy (MIILE) with circular staplers have reported better outcomes compared to MIE with cervical anastomosis, but frequent anastomotic complications have also been reported. MIILE with linear staplers is a promising alternative, but the long-term functional and oncological outcomes are uncertain. Read More
