BACKGROUND: Preeclampsia is a multi-system, hypertensive disorder of pregnancy that increases a woman's risk of later-life cardiovascular disease. Breastfeeding may counteract the negative cardiovascular sequela associated with preeclampsia; however, women who develop preeclampsia may be at-risk for suboptimal breastfeeding rates. In this case series, we present three cases of late-onset preeclampsia and one case of severe gestational hypertension that illustrate a potential association between hypertensive disorders of pregnancy and suboptimal breastfeeding outcomes, including delayed onset of lactogenesis II and in-hospital formula supplementation...

Objective Cerebral vasospasm(CVS) after Subarachnoid hemorrhage (SAH) can cause delayed cerebral ischemia,secondary cerebral infarction, and rehemorrhage, which are the leading causes of mutilation and death. Nimodipine has been shown to prevent CVS. Magnesium ion (Mg2+ ) can competitively inhibit the influx of calcium (Ca2+ ) and prevent vasospasm. There is evidence that magnesium sulfate can prevent CVS and reduce infarct volume after SAH. In this study, we evaluated the efficacy and safety of intravenous magnesium sulfate combined with oral nimodipine on CVS, delayed cerebral ischemia, secondary cerebral infarction, and rehemorrhage after SAH...

This paper extends the study of the induced temperature change in the mesostructure and in the physical properties occurring in aqueous mixtures of the ionic liquid 1-ethyl-3-methyl imidazolium octyl-sulfate [EMIm][OSO4 ]. For some compositions, these mixtures undergo a phase transition between the liquid (isotropic in the mesoscale) and the mesomorphic state (lyotropic liquid crystalline) at about room temperature. The behavior of mixtures doped with a divalent metal sulfate was investigated in order to observe their applicability as electrolytes...

A screening method for simultaneous analysis of 379 pesticides in human serum was developed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Electrospray ionization with positive/negative switching mode of LC-MS/MS was adopted and scheduled multiple reaction monitoring for each target compound was established. The limit of quantitation was 10 ng/mL for 94.5% of the total pesticides and the correlation coefficients of calibration were ≥0.990 for 93.9% of the pesticides. For the sample preparation, scaled-down QuEChERS were used...

Growth in sodium chloride (NaCl) is known to induce stress in non-halophilic microorganisms leading to effects on the microbial metabolism and cell structure. Microorganisms have evolved a number of adaptations, both structural and metabolic, to counteract osmotic stress. These strategies are well-understood for organisms in NaCl-rich brines such as the accumulation of certain organic solutes (known as either compatible solutes or osmolytes). Less well studied are responses to ionic environments such as sulfate-rich brines which are prevalent on Earth but can also be found on Mars...

Aim: The aim of the present study was to assess the protective effects of magnesium sulfate (MgSO4 ) on ischemia/reperfusion (I/R) induced ovarian damage in a rat ovarian torsion model. Methods: Forty-two female Sprague Dawley rats were included in the study. They were divided into six groups as Group 1, sham; Group 2, bilateral ovarian torsion; Group 3, bilateral ovarian torsion-detorsion; Group 4, MgSO4 -sham; Group 5, MgSO4 -bilateral ovarian torsion; Group 6, bilateral ovarian torsion-MgSO4 -detorsion...

BACKGROUND: The distal radius fracture represent until 15% of all bone injuries in adults. The key in the recovery of mobility and functional outcomes are rehabilitation. The intra-articular application of magnesium sulphate has been used for postoperative pain. The objective was to determinate the improvement in pain and functional outcome of patients with distal radius fracture using intra-articular magnesium sulphate. MATERIAL AND METHODS: Patients with distal radius fracture treated with percutaneous pinning and cast immobilization was included and randomized into two groups...

OBJECTIVE:  To evaluate the association of magnesium sulfate (MgSO4 ) exposure and candidate gene polymorphisms with adverse neurodevelopmental outcomes following preterm birth. STUDY DESIGN:  We performed a nested case-control analysis of a randomized trial of maternal MgSO4 before anticipated preterm birth for the prevention of cerebral palsy (CP). Cases were children who died within 1 year of life or were survivors with abnormal neurodevelopment at age 2 years...

PURPOSE: Hematopoietic cell transplant (HCT) recipients often require intravenous (IV) magnesium repletion due to poor dietary intake, gastrointestinal loss, and use of concomitant magnesium wasting medications. Prolonging the IV magnesium infusion rate has been postulated to reduce renal clearance and improve retention; however, limited evidence supports this hypothesis. METHODS: We reviewed autologous and allogeneic HCT recipients (n = 82) who received IV magnesium at our institution between 2014 and 2016: 41 patients received IV magnesium at a prolonged rate of 0...

Background: The aim of this trial was to evaluate the safety and efficacy of oral hydration as a substitute for intravenous hydration after cisplatin (CDDP) administration. Methods: The major eligibility criteria included patients with lung cancer, indications for a CDDP-based regimen at a dose of 60 mg/m2 or higher, an age of between 20 and 74 years and adequate renal function. Antiemetic prophylaxis consisted of an appropriate dose of palonosetron, aprepitant, dexamethasone and magnesium sulfate (8 mEq)...

Posterior reversible encephalopathy syndrome (PRES) is a potentially reversible failure of cerebral autoregulation managed by correction of hypertension or underlying medical condition. Nonresponding cases progress to irreversible brain damage. There is some evidence of association of hypomagnesemia with PRES. We describe a case of nonresolving PRES where use of magnesium sulfate led to improvement in neurological function and eventual recovery. Our case highlights the need for a randomized controlled trial to test the efficacy of magnesium in PRES...

Single crystals of potassium magnesium chloride sulfate (KMCS) doped with cobalt ions were grown by slow cooling method. Powder XRD study confirmed the monoclinic structure of the grown crystals. The functional group vibrations were checked through FTIR spectroscopy measurements. In optical studies, the absorbance behavior of the crystals and their optical energy gap were established by Tauc plot. The refractive index, the extinction coefficient and other optical constants were calculated for the grown crystals...

BACKGROUND: Globally, the rate of reduction in delivery-associated maternal and perinatal mortality has been slow compared to improvements in post-delivery mortality in children under five. Improving clinical readiness for basic obstetric emergencies is crucial for reducing facility-based maternal deaths. Emergency readiness is commonly assessed using tracers derived from the maternal signal functions model. OBJECTIVE-METHOD: We compare emergency readiness using the signal functions model and a novel clinical cascade...

Posterior reversible encephalopathy syndrome (PRES) is a newly defined syndrome; therefore, this transient clinical condition is not well known and probably underdiagnosed. It develops quickly with symptoms that are usually indistinguishable from eclampsia. Nurses need to be knowledgeable and aware of identifying symptoms and appropriate treatment. The condition is thought to share pathophysiology with eclampsia, and it is suggested that endothelial dysfunction combined with hypertension causes disruption in the blood brain barrier resulting in cerebral edema...

The impact of vanadium (V) and magnesium (Mg) applied as sodium metavanadate (SMV, 0.125 mg V/ml) and magnesium sulfate (MS, 0.06 mg Mg/ml) on oxidative stress markers in bone of male Wistar rats was investigated. Some of them were also measured in the liver, e.g. l-ascorbic acid (hepatic L-AA). Additionally, relationships between selected indices determined in bone were examined. SMV alone (Group II) did not significantly alter the level of TBARS and the activity of SOD, compared with the control (Group I), but it slightly reduced the GR activity (by 13%) and the L-AA level (by 15...

INTRODUCTION: Magnesium sulfate is the drug of choice for prevention of seizures in the pre-eclamptic woman. There is no agreement in the published randomized trials regarding the optimal time to initiate magnesium sulfate, the dose to use (both loading and maintenance) as well as the duration of therapy. The objective of this study is to determine whether magnesium sulfate prophylaxis is needed for up to 24 hours postpartum in all patients with severe pre-eclampsia for the prevention of seizure...
