Caldwell, et al., "Preclinical investigation of Pegylated arginase 1 as a treatment for retina and brain injury.", Experimental neurology, vol. 348, pp. 113923, 2022. Abstract

Arginase 1 (A1) is the enzyme that hydrolyzes the amino acid, L-arginine, to ornithine and urea. We have previously shown that A1 deletion worsens retinal ischemic injury, suggesting a protective role of A1. In this translational study, we aimed to study the utility of systemic pegylated A1 (PEG-A1, recombinant human arginase linked to polyethylene glycol) treatment in mouse models of acute retinal and brain injury. Cohorts of WT mice were subjected to retinal ischemia-reperfusion (IR) injury, traumatic optic neuropathy (TON) or brain cerebral ischemia via middle cerebral artery occlusion (MCAO) and treated with intraperitoneal injections of PEG-A1 or vehicle (PEG only). Drug penetration into retina and brain tissues was measured by western blotting and immunolabeling for PEG. Neuroprotection was measured in a blinded fashion by quantitation of NeuN (neuronal marker) immunolabeling of retina flat-mounts and brain infarct area using triphenyl tetrazolium chloride (TTC) staining. Furthermore, ex vivo retina explants and in vitro retina neuron cultures were subjected to oxygen-glucose deprivation (OGD) followed by reoxygenation (R) and treated with PEG-A1. PEG-A1 given systemically did not cross the intact blood-retina/brain barriers in sham controls but reached the retina and brain after injury. PEG-A1 provided neuroprotection after retinal IR injury, TON and cerebral ischemia. PEG-A1 treatment was also neuroprotective in retina explants subjected to OGD/R but did not improve survival in retinal neuronal cultures exposed to OGD/R. In summary, systemic PEG-A1 administration is neuroprotective and provides an excellent route to deliver the drug to the retina and the brain after acute injury.

Fouda, "Efficacy and safety of two doses of low molecular weight heparin (enoxaparin) in pregnant women with a history of recurrent abortion secondary to antiphospholipid syndrome.", Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology, vol. 30, issue 8, pp. 842-6, 2010. Abstract

The aim of this randomised controlled trial was to compare efficacy and safety of two doses of low molecular weight heparin (enoxaparin) in pregnant women with a history of recurrent abortion secondary to antiphospholipid syndrome. A total of 60 women with a minimum of three consecutive abortions before 10 weeks' gestation and positive lupus anticoagulant and/or anticardiolipin antibodies on at least two occasions at least 12 weeks apart were randomised into two groups based on computer generated randomisation list concealed in opaque envelopes. Pregnant women were treated with enoxaparin 40 mg plus low dose aspirin (LDA) (n = 30) or enoxaparin 20 mg plus LDA (n = 30). The live birth rate was 76.67% in enoxaparin 40 mg group and 70% in enoxaparin 20 mg group (p value = 0.559). There were no significant differences between both groups with respect to neonatal outcome, obstetric and maternal complications during pregnancy or puerperium. No cases of severe bleeding, thrombocytopenia or spontaneous fractures were reported in both groups.

Fouda, R., H. Ammar, E. Sobhy, and A. M. Amin, "Unusual cause of pericardial effusion.", BMJ case reports, vol. 2012, 2012. Abstract

A 65-year-old Egyptian lady suffering from non-alcoholic liver cirrhosis was referred to our unit for evaluation of a massive pericardial effusion. Few weeks before presentation, she suffered from progressive abdominal distention and dyspnoea. She denied fever, rigors or other cardiorespiratory symptoms. Examination revealed shrunken liver, spleenomegaly and ascites. Chest was clear to auscultation and heart sounds were distant. Chest radiograph showed cardiomegaly and clear lung fields. Abdominal ultrasound confirmed the results of abdominal examination. Transthoracic echocardiogram (TTE) revealed a massive pericardial effusion (PEF) and rheumatic mitral stenosis. Chest tomography showed PEF and clear lung fields. One litre of exudate was removed via TTE-guided needle pericardiocentesis. A pericardio-peritoneal shunt was suspected, which was confirmed via a radioisotopic study. This case is among very few cases that reported PEF in a cirrhotic ascetic patient secondary to a radio-isotopically confirmed pericardio-peritoneal shunt in the literature.

Fouda, U. M., and A. M. Sayed, "Extended high dose letrozole regimen versus short low dose letrozole regimen as an adjuvant to gonadotropin releasing hormone antagonist protocol in poor responders undergoing IVF-ET.", Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, vol. 27, issue 12, pp. 1018-22, 2011 Dec. Abstract

OBJECTIVE: To compare the efficacy and cost-effectiveness of extended high dose letrozole regimen/HPuFSH-gonadotropin releasing hormone antagonist (GnRHant) protocol with short low dose letrozole regimen/HPuFSH-GnRHant protocol in poor responders undergoing IVF-ET.

METHODS: In this randomized controlled trial, 136 women who responded poorly to GnRH agonist long protocol in their first IVF cycle were randomized into two equal groups using computer generated list and were treated in the second IVF cycle by either extended letrozole regimen (5 mg/day during the first 5 days of cycle and 2.5 mg/day during the subsequent 3 days) combined with HPuFSH-GnRHant protocol or short letrozole regimen (2.5 mg/day from cycle day 3-7) combined with HPuFSH-GnRHant protocol.

RESULTS: There were no significant differences between both groups with regard to number of oocytes retrieved and clinical pregnancy rate (5.39 ± 2.08 vs. 5.20 ± 1.88 and 22.06% vs. 16.18%, respectively).The total gonadotropins dose and medications cost per cycle were significantly lower in extended letrozole group (44.87 ± 9.16 vs. 59.97 ± 14.91 ampoules and 616.52 ± 94.97 vs. 746.84 ± 149.21 US Dollars ($), respectively).The cost-effectiveness ratio was 2794 $ in extended letrozole group and 4616 $ in short letrozole group.

CONCLUSION: Extended letrozole regimen/HPuFSH-GnRHant protocol was more cost-effective than short letrozole regimen/HPuFSH-GnRHant protocol in poor responders undergoing IVF-ET.

A 16-years-old Egyptian girl presented with massive pericardial effusion, fever, weight loss and hoarseness of voice. Laryngoscopy showed left vocal cord paralysis. Chest CT revealed pericardial effusion, amalgamated mediastinal lymph nodes and clear lung fields. Pericardial fluid analysis revealed a lymphocytic exudate with high adenosine deaminase enzyme level, negative stains and cultures for bacteria and fungi. Despite a negative nucleic acid test for tuberculosis; antituberculous and corticosteroids therapies resulted in resolution of pericardial effusion after 3 weeks but hoarseness of voice persisted. Few cases of vocal cord paralysis with tuberculous mediastinal lymphadenopathy were reported in English literature.
