Chlorinated pesticide residues in human breast milk collected from southern Jordan in 2012/2013

Chlorinated pesticide residues in human breast milk from five southern Jordan districts were analyzed in 2012/2013. The total number of samples from all districts was 100. The number of samples gathered from each district was collected according to their population densities. The present study shows that 59% of the samples which contained pesticides’ residues were p,p’-DDE, 30% contained β-HCH, 10% contained p,p′-DDT, 6% contained α-HCH, 2% contained heptachlor and 1% contained endrin. These human milk samples were free of aldrin, dieldrin, α-endosulfan, β-endosulfan, HCB, γ-HCH, o,p′-DDD, o,p′-DDT and o,p′-DDE. The levels of the six mentioned compounds detected in all mother’s milk samples were higher in Ghor El-Safi district compared with the other four districts. In this study, it is recommended to continue the pesticides residues monitoring in all parts of Jordan, particularly in Ghor El-Safi district and other regions in the cultivated Jordan Valley.     

Novel pharmacologic therapy of heart failure

Opinion statement The prevalence of congestive heart failure is progressively increasing and despite recent advances in therapeutics, there is a continuing need for novel effective therapies. New, investigational treatment strategies include inotropic drugs, neurohormonal antagonists, anticytokine and anti-inflammatory strategies, hormonal therapies, and nutritional supplements. Current positive inotropes (eg, dobutamine and phosphodiesterase inhibitors) provide symptomatic relief, but newer agents may have a better adverse effect profile. Angiotensin-converting enzyme (ACE) inhibitors should remain first-line treatment with angiotensin receptor blockers used in ACE inhibitor-intolerant patients. Many new neurohormonal antagonists have recently been investigated and eplerenone has demonstrated clinical benefit. New hormonal, anticytokine, and anti-inflammatory therapies have shown benefit in small trials, but results in larger trials have been disappointing. Other approaches are currently being tested in large trials that will clarify their role. Nutritional supplements need to be tested in a large prospective trial before they can be recommended.     

Mnemonic to Assist in Management of Liver Cirrhosis

Cirrhosis is a challenge for nurse practitioners in terms of providing effective management. The goals of this article are to provide readers with a general view of the pathophysiological complications of cirrhosis and to describe a mnemonic to assist in its management. Using mnemonics has been shown to reduce clinical errors and improve adherence to best practices. Mnemonics provide immediate access to relevant knowledge of complex concepts. The use of a mnemonics strategy in cirrhosis acts as an aid for translating pathophysiological and pharmaco-therapeutic concepts into meaningful interventions.     

Idiopathic hyperzincemia with associated copper deficiency anemia: a diagnostic dilemma

Prompt serum copper and zinc in addition to vitamin B12 levels should be measured in patients suffering from refractory anemia with neurological symptoms. A timely copper supplementation can help revert the hematological and possibly the neurological manifestations.     

The poetics of mourning and faith-based intervention in maladaptive grieving processes in Ethiopia

The paper is an inquiry into the poetics of mourning and faith-based intervention in maladaptive grieving processes in Ethiopia. The paper discusses the ways that loss is signified and analyzes the meanings of ethnocultural and psychospiritual practices employed to deal with maladaptive grief processes and their psychological and emotional after-effects. Hermeneutics provided the methodological framework and informed the analysis. The thesis of the paper is that the poetics of mourning and faith-based social interventions are interactionally based meaning making processes. The paper indicates the limitations of the study and their implications for further inquiry.     

Anti-ulcerogenic activity of aqueous extract of Carica papaya seed on indomethacin-induced peptic ulcer in male albino rats

OBJECTIVE: Carica papaya is an important fruit with its seeds used in the treatment of ulcer in Nigeria. This study investigated the anti-ulcerogenic and antioxidant activities of aqueous extract of Carica papaya seed against indomethacin-induced peptic ulcer in male rats.METHODS: Thirty male rats were separated into 6 groups(A–F) of five rats each. For 14 d before ulcer induction with indomethacin, groups received once daily oral doses of vehicle(distilled water), cimetidine 200 mg/kg body weight(BW), or aqueous extract of C. papaya seed at doses of 100, 150 or 200 mg/kg BW(groups A, B, C, D, E and F, respectively). Twenty-four hours after the last treatment, groups B, C, D, E and F were treated with 100 mg/kg BW of indomethacin to induce ulcer formation. RESULTS: Carica papaya seed extract significantly(P<0.05) increased gastric p H and percentage of ulcer inhibition relative to indomethacin-induced ulcer rats. The extract significantly(P<0.05) decreased gastric acidity, gastric acid output, gastric pepsin secretion, ulcer index and gastric secretion volume relative to group B. These results were similar to that achieved by pretreatment with cimetidine. Specific activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase in the extract-treated groups(D, E and F) were increased significantly over the group B(P<0.05). Pretreatment with the seed extract protected rats from the indomethacin-mediated decrease in enzyme function experienced by the group B. Similarly, indomethacin-mediated decrease in reduced glutathione level and indomethacin-mediated increase in malondialdehyde were reversed by Carica papaya extract. CONCLUSION: In this study, pretreatment with aqueous extract of Carica papaya seed exhibited antiulcerogenic and antioxidant effects, which may be due to the enhanced antioxidant enzymes.     

Recent US Case of Variant Creutzfeldt-Jakob Disease—Global Implications

Variant Creutzfeldt-Jakob disease (vCJD) is a rare, fatal prion disease resulting from transmission to humans of the infectious agent of bovine spongiform encephalopathy. We describe the clinical presentation of a recent case of vCJD in the United States and provide an update on diagnostic testing. The location of this patient’s exposure is less clear than those in the 3 previously reported US cases, but strong evidence indicates that exposure to contaminated beef occurred outside the United States more than a decade before illness onset. This case exemplifies the persistent risk for vCJD acquired in unsuspected geographic locations and highlights the need for continued global surveillance and awareness to prevent further dissemination of vCJD.

The use of recombinant tissue plasminogen activator in in acute ischemic stroke is associated with increased level of BDNF

Much concern was directed towards the crucial role of recombinant tissue plasminogen activator (rt-PA) in improving neuroplasticity in patients with acute ischemic stroke. The aim of the work to investigate the effect of treating patients with acute ischemic stroke with rt-PA, on the level of brain derived neurotrophic factor (BDNF) as a marker of neuroplasticity. This study was conducted on 47 patients presenting with acute ischemic stroke (during the first 4.5 h from stroke onset); 26 patients of them eligible for receiving rt-PA (patient group) and 21 patients having contraindications for treatment with rt-PA (control group). Neurological, radiological and laboratory assessment (including BDNF serum level) were done for both groups at stroke onset (before receiving rt-PA) and at day 7. There was a statistically significant increase in BDNF serum level from day 1 to day 7 in rt-PA treated patients in comparison to control group (P-value? 0.001). Serum level of BDNF is significantly higher at the onset of stroke in female patients and non-smokers than males or smokers (P-value?=?0.011, 0.01 respectively). There was no effect of either age, body mass index, hypertension, diabetes, drug abuse, past or family history of stroke, valvular heart diseases, atrial fibrillation, cardiomyopathy, ejection fraction, carotid atherosclerotic changes, lipid profile or uric acid, on BDNF serum level measured at the onset of stroke. Treatment of patients with acute ischemic stroke with rt-PA causes significant improvement in neuroplasticity through increasing BDNF serum level.
