BackgroundGlobal health initiatives have enabled the scale up of antiretroviral treatment (ART) over recent years. The impact of HIV‐specific funds and programmes on non‐HIV‐related health services and health systems in genera has been debated extensively. Drawing on evidence from Malawi and Ethiopia, this article analyses the effects of ART scale‐up interventions on human resources policies, service delivery and general health outcomes, and explores how synergies can be maximized.MethodsData from Malawi and Ethiopia were compiled between 2004 and 2009 and between 2005 and 2009, respectively. We developed a conceptual health systems framework for the analysis. We used the major changes in human resources policies as an entry point to explore the wider health systems changes.ResultsIn both countries, the need for an HIV response triggered an overhaul of human resources policies. As a result, the health workforce at health facility and community level was reinforced. The impact of this human resources trend was felt beyond the scale up of ART services; it also contributed to an overall increase in functional health facilities providing curative, mother and child health, and ART services. In addition to a significant increase in ART coverage, we observed a remarkable rise in user rates of non‐HIV health services and an improvement in overall health outcomes.ConclusionsInterventions aimed at the expansion of ART services and improvement of long‐term retention of patients in ART care can have positive spill‐over effects on the health system. The responses of Malawi and Ethiopia to their human resources crises was exceptional in many respects, and some of the lessons learnt can be useful in other contexts. The case studies show the feasibility of obtaining improved health outcomes beyond HIV through scaled‐up ART interventions when these are part of a long‐term, system‐wide health plan supported by all decision makers and funders.

Abstract
Introduction
The timely provision of critical care to hospitalised patients at risk for cardiopulmonary arrest is contingent upon identification and referral by frontline providers. Current approaches require improvement. In a single-centre study, we developed the Bedside Paediatric Early Warning System (Bedside PEWS) score to identify patients at risk. The objective of this study was to validate the Bedside PEWS score in a large patient population at multiple hospitals.

Methods
We performed an international, multicentre, case-control study of children admitted to hospital inpatient units with no limitations on care. Case patients had experienced a clinical deterioration event involving either an immediate call to a resuscitation team or urgent admission to a paediatric intensive care unit. Control patients had no events. The scores ranged from 0 to 26 and were assessed in the 24 hours prior to the clinical deterioration event. Score performance was assessed using the area under the receiver operating characteristic (AUCROC) curve by comparison with the retrospective rating of nurses and the temporal progression of scores in case patients.

Results
A total of 2,074 patients were evaluated at 4 participating hospitals. The median (interquartile range) maximum Bedside PEWS scores for the 12 hours ending 1 hour before the clinical deterioration event were 8 (5 to 12) in case patients and 2 (1 to 4) in control patients (P < 0.0001). The AUCROC curve (95% confidence interval) was 0.87 (0.85 to 0.89). In case patients, mean scores were 5.3 at 20 to 24 hours and 8.4 at 0 to 4 hours before the event (P < 0.0001). The AUCROC curve (95% CI) of the retrospective nurse ratings was 0.83 (0.81 to 0.86). This was significantly lower than that of the Bedside PEWS score (P < 0.0001).

Conclusions
The Bedside PEWS score identified children at risk for cardiopulmonary arrest. Scores were elevated and continued to increase in the 24 hours before the clinical deterioration event. Prospective clinical evaluation is needed to determine whether this score will improve the quality of care and patient outcomes.

Purpose Bortezomib has demonstrated promising activity in patients with follicular lymphoma (FL). This is the first study to evaluate the safety and efficacy of bortezomib added to rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP) in previously untreated advanced-stage FL. Patients and Methods This is a phase II multicenter trial adding bortezomib (1.3 mg/m2 days 1 and 8) to standard-dose R-CVP (BR-CVP) for up to eight cycles in patients with newly diagnosed stage III/IV FL requiring therapy. Two co-primary end points, complete response rate (complete response [CR]/CR unconfirmed [CRu]) and incidence of grade 3 or 4 neurotoxicity, were assessed. Results Between December 2006 and March 2009, 94 patients were treated with BR-CVP. Median patient age was 57 years (range, 29 to 84 years), and the majority had a high (47%) or intermediate (43%) Follicular Lymphoma International Prognostic Index score. BR-CVP was extremely well tolerated, with 90% of patients completing the intended eight cycles. No patients developed grade 4 neurotoxicity, and only five of 94 patients (5%; 95% CI, 0.8% to 9.9%) developed grade 3 neurotoxicity, which was largely reversible. On the basis of an intention-to-treat analysis, 46 of 94 patients (49%; 95% CI, 38.8% to 59.0%) achieved a CR/CRu, and 32 of 94 patients (34%) achieved a partial response, for an overall response rate of 83% (95% CI, 75.4% to 90.6%). Conclusion The addition of bortezomib to standard-dose R-CVP for advanced-stage FL is feasible and well tolerated with minimal additional toxicity. The complete response rate in this high-risk population compares favorably to historical results of patients receiving R-CVP. Given these results, a phase III trial comparing BR-CVP with R-CVP is planned.

Introduction Retrospective studies suggest that p53 alteration is prognostic for recurrence in patients with urothelial bladder cancer and predictive for benefit from combination methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) adjuvant chemotherapy. Patients and Methods Patients with pT1/T2N0M0 disease whose tumors demonstrated ≥ 10% nuclear reactivity on centrally performed immunohistochemistry for p53 were offered random assignment to three cycles of adjuvant MVAC versus observation; p53-negative patients were observed. By using a log-rank test with one-sided α = .05 and β = .10, 190 p53-positive patients were planned to be randomly assigned to detect an absolute improvement in probability of recurring by 3 years from 0.50 to 0.30. Results A total of 521 patients were registered, 499 underwent p53 assessment, 272 (55%) were positive, and 114 (42%) were randomly assigned. Accrual was halted on the basis of the data and safety monitoring board review of a futility analysis. Overall 5-year probability of recurring was 0.20 (95% CI, 0.16 to 0.24) with no difference on the basis of p53 status. Only 67% of patients randomly assigned to MVAC received all three cycles with 12 patients receiving no treatment. There was no difference in recurrence in the randomly assigned patients (hazard ratio, 0.78; 95% CI, 0.29 to 2.08; P = .62). Conclusion Neither the prognostic value of p53 nor the benefit of MVAC chemotherapy in patients with p53-positive tumors was confirmed, but the high patient refusal rate, lower than expected event rate, and failures to receive assigned therapy severely compromised study power.

Purpose This study was designed to determine the incidence of venous and arterial thromboembolic events (TEEs) in patients treated with cisplatin-based chemotherapy and to analyze the prognostic value of patients' baseline and treatment characteristics in predicting TEE occurrence. Patients and Methods We performed a large retrospective analysis of all patients treated with cisplatin-based chemotherapy for any type of malignancy at Memorial Sloan-Kettering Cancer Center in 2008. A TEE was cisplatin-associated if it occurred between the time of the first dose of cisplatin and 4 weeks after the last dose. Results Among 932 patients, 169 (18.1%) experienced a TEE during treatment or within 4 weeks of the last dose. TEEs included deep vein thrombosis (DVT) alone in 49.7%, pulmonary embolus (PE) alone in 25.4%, DVT plus PE in 13.6%, arterial TEE alone in 8.3%, or DVT plus arterial TEE in 3.0%. TEEs occurred within 100 days of initiation of treatment in 88% of patients. By univariate analysis, sex, age, race, Karnofsky performance status (KPS), exposure to erythropoiesis-stimulating agents, presence of central venous catheter (CVC), site of cancer, stage of cancer, leukocyte and hemoglobin levels, and Khorana score were all identified as risk factors. However, by multivariate analysis, only age, KPS, presence of CVC, and Khorana score retained significance. Conclusion This large retrospective analysis confirms the unacceptable incidence of TEEs in patients receiving cisplatin-based chemotherapy. In view of the controversy associated with prophylactic anticoagulation in patients with cancer treated with chemotherapy, randomized studies are urgently needed in this specific cancer population treated with cisplatin-based regimens.
Die Argumentation des Patriarchen Gregorios II. Kyprios zur Widerlegung des Filioque-Ansatzes in der Schrift. De processione Spiritus sancti
Authors: Alexopoulos Theodoros 
Published: August 2011

Abstract
Focussing on the thirteenth-century endings of Byzantine writings against the Latin innovation of the Filioque, the present study aims, on the basis of the work De processione Spiritus sancti (1283), to provide the reader with an insight into the nature of the Orthodox argumentation refuting the Filioque. The work was until now attributed to Gregorios Kyprios Patriarch of Konstantinople (1283–1289). However, it is not a product of his pen, but a compiled version of his earlier work, the “Antirrheticos against Bekkos”. Throughout the study the writer follows step by step Kyprios' reasoning and tries to control the validity and soundness of the arguments advanced, making at the same time specific references to the patristic and philosophical background of Kyprios' thinking. The study shows beyond any doubt that Kyprios is indebted to his predecessors, mostly to the Cappadocians and Dionysius Areopagites, and that he argues on the same line of reasoning with them in respect to the idea of the “Monarchy” of the Father, of the incommunicable of hypostatic properties, and of the possibility of beings to be in communion with God only through the divine energies. On the ground of these three fundamental ideas, a procession of the Spirit also from the Son is categorically rejected. Only the mission of the Spirit (what is implied here, are the gifts of the Spirit and not the Spirit itself) into the world through the Son is acceptable.

Abstract.
We compute the integral cohomology ring of configuration spaces of two points on a given real projective space. Apart from an integral class, the resulting ring is a quotient of the known integral cohomology of the dihedral group of order 8 (in the case of unordered configurations, thus has only 2- and 4-torsion) or of the elementary abelian
2-group of rank 2 (in the case of ordered configurations, thus has only 2-torsion). As an application, we complete the computation of the symmetric topological complexity of real projective
spaces with and .
Light and electron microscopic studies on Myxobolus egyptica sp. nov. (Myxozoa, Myxosporea), infecting the hornlip mullet Oedalechilus labiosus from the Red Sea
Authors: Abdel-Baki Abdel-Azeem 
Published: August 2011

AbstractA new myxosporean, Myxobolus egyptica sp. nov., was described from the gills of the hornlip mullet Oedalechilus labiosus, collected from the Red Sea at Al-Quseir city, Egypt. The prevalence of infection was 12/72 (16.66%). Myxobolus egyptica was identified on the basis of spore morphometry, histology and transmission electron microscopy. It was distinguished from all previously reported Myxobolus spp. by its shape, dimensions of the mature spore 10.0 ± 0.6 (9.5–10.5) μm in length, 8.5 ± 0.4 (8.0–9.0) μm in width and 8.7 ± 0.5 (8.4–9.2) μm in thickness, polar capsules, locality and host. The parasite formed intrafilamental cyst-like plasmodia. These plasmodia caused curling and atrophy of the gill lamellae. The ultrastructural analysis revealed a double-unit plasmodial membrane which was in direct contact with the host cells and had numerous vesicles. Some mitochondria were found below this membrane. The disporic pansporoblast was earliest recognizable stage of sporogenesis. Advanced developmental stages of spores and mature spores were reported.

Published: August 2011

AbstractA new species of Kritskyia Kohn, 1990 (Monogenea, Dactylogyridae, Ancyrocephalinae) is described from the urinary bladder of Salminus brasiliensis (Cuvier, 1816) (Characiformes, Characidae) from the Cuiabá River, the Pantanal wetlands, Brazil. The male copulatory apparatus of the new species differs from those of other species of the genus by the presence of a bipartite accessory piece (distally and proximally linked), one part grooved, serving as guide for distal portion of the MCO. Moreover, the vagina of the new species differs from those of congeners by possessing distal digitiform processes.
Redescription of Monocotyle myliobatis (Monogenea, Monocotylidae) from the type host Myliobatis aquila (Elasmobranchii, Myliobatidae) off the Algerian coast

Published: August 2011

AbstractMonocotyle was proposed by Taschenberg (1878) to accommodate M. myliobatis Taschenberg, 1878 from the gills of Myliobatis aquila (Linnaeus) caught at the Aquarium of the Zoological Station of Naples (Italy). There have been three descriptions of this species: the original one by Taschenberg (1878) and two which are incomplete by Perugia and Parona (1890) and Palombi (1942). Illustrations by these authors are poor and sometimes conflicting. We have rediscovered M. myliobatis on the gills of the type host Myliobatis aquila caught near Algiers, Tamentfoust (36°47′N, 3°12′E) (Algeria). We provide new illustrations of this monogenean, based on new specimens. We also redescribe the anatomy, with special attention to the male and female reproductive systems, and we provide additional data regarding the morphology, the number and arrangement of the septal sclerites of the haptor and the haptoral marginal papillae. We indicate the similarity between Monocotyle myliobatis and Monocotyle sp. Euzet et Maillard, 1967 collected from Pteromyleus bovinus, Geoffroy Saint Hillaire (Elasmobranchii, Myliobatidae) by J. Cadenat off Dakar (Senegal).
Polylabris bengalensis sp. nov. (Monogenea, Microcotylidae) from siganid fishes of the Visakhapatnam coast, Bay of Bengal, India
Authors: Sailaja Bade , Madhavi Rokkam 
Published: August 2011

AbstractA new species Polylabris bengalensis (Monogenea, Microcotylidae) is described from the gills of the siganid fishes, Siganus javus and S. oramin from the coast of Visakhapatnam, Bay of Bengal, India. It most closely resembles P. mamaevi but differs in having unequal caeca terminating at different levels in the haptor, in the follicular testis forming a compact mass, in the presence of a thick layer of concentric muscles surrounding the genital atrium and in the terminal part of the male copulatory organ not recurved. The validity of various species of Polylabris recorded from siganids from different geographical regions is discussed.

AbstractNeolepidapedoides subantarcticus sp. nov. (Digenea, Lepocreadiidae) is reported from the intestine, mainly the jejunum, of fishes in the eastern mouth of the Beagle Channel and in the harbour of Ushuaia in the Beagle Channel (Tierra del Fuego, Argentina) at a depth 7–30 m. The typical host is Patagonotothen longipes, other hosts are P. tessellata, P. brevicauda and Champsocephalus esox. The male terminal genitalia indicates that the new species belongs to the genus Neolepidapedoides (Lepocreadiidae, Lepocreadiinae). The most important taxonomic features are the presence of eye-spots, the spined tegument, the “Opechona-type” cirrus-sac, the external seminal vesicle free in the parenchyma, the gonads arranged in tandem, the vitelline follicles extending from the level of the oesophagus in the forebody to the posterior end of the body and an I-shaped excretory vesicle reaching to the intestinal bifurcation and the absence of a pseudoesophagus. Ten previously described species differ from the N. subantarcticus sp. nov. mainly in the extent of the vitelline fields and length of the excretory vesicle which reaches into forebody.
A new species of Hysterothylacium (Ascaridoidea, Anisakidae) parasitic in Zenopsis conchifer (Zeiformes, Zeidae) from Argentinean waters

Published: August 2011

AbstractA new species of parasitic nematode, Hysterothylacium spirale sp. nov. (Ascaridoidea, Anisakidae), is described based on specimens collected from the intestine and pyloric caeca of the silvery john dory Zenopsis conchifer (Lowe) (Zeiformes, Zeidae), from the Argentinean Shelf (35°05′–40°46′S, 53°03′–58°07′W). Among the 66 valid species described so far in the genus, the new species most closely resembles H. zenis (Baylis, 1929). Both species, apparently specific for fishes of the family Zeidae, share the shape of the dorsal lip, the long expanded lateral alae originating from subventral interlabia and the ornamentation of the tail tip, as well as general morphometry. The combination of these shared features distinguishes both species from all congeners so far known. However, the new species is distinguishable from H. zenis by having shorter interlabia, and consequently the lateral alae originating more posteriorly, shorter spicules, a smaller number of postcloacal papillae and the presence of two pairs of double postcloacal papillae.

AbstractA new monobasic genus of parasitic mites, Phalarophilus fulicarius gen. nov., sp. nov. (Acariformes, Syringophilidae) is described from feather quills of Phalaropus fulicarius (Linnaeus) (Charadriiformes, Scolopacidae) from USA. Females of the new genus differs from those of the genus Bochkovia Skoracki et OConnor, by having the rounded posteriorly stylophore, edentate movable cheliceral digits, propodonotal setae arranged 2-1-1-2, thin and smooth dorsal setae of the idiosoma, smooth dorsal setae of legs I and II, and by the presence of setae vsI; males are distinguished by the presence of the propodonotal setae arranged 2-1-1-1-1. Additionally, two new syringophilid species recorded from aquatic birds in North America and three new host associations of these mites are recovered.
Effects of Sodium Octanoate, Acylated Ghrelin, and Desacylated Ghrelin on the Growth of Genetically Engineered Escherichia Coli

Published: August 2011

Effects of Sodium Octanoate, Acylated Ghrelin, and Desacylated Ghrelin on the Growth of Genetically EngineeredEscherichia ColiAcylated ghrelin is a 28-amino acid peptide hormone bearing a fatty acid group based on octanoic acid (caprylic acid) at the serine which is located at position 3 and at the N-terminus. If this fatty acid is cleaved from acylated ghrelin, the remaining peptide is referred to as desacylated ghrelin. Free fatty acids (FFAs) can kill or inhibit the growth of bacteria. The purpose of this study was to test this ability using acylated ghrelin, desacylated ghrelin, and sodium octanoate (caprylic acid) as carbon sources for the genetically engineeredEscherichia colistrains MK79 and MK57. For this experimental work, minimal medium was modified by replacing glucose with equal concentrations of acylated ghrelin, desacylated ghrelin, or sodium octanoate. Bacterial optical density, viability, alpha-amylase production, plasmid stability and pH of the growth medium were measured during these experiments. The media that allowed most growth, based on viable cell counts and the OD600of MK79, was minimal medium, followed by the medium containing desacylated ghrelin or acylated ghrelin, and finally the medium containing sodium octanoate. The same order was observed for MK57. Neither of the strains lost plasmids during the entire course of each experiment. There was also little change in the pH of any of the media used for both strains. These results suggest that sodium octanoate, acylated ghrelin, and desacylated ghrelin, when compared with minimal medium, inhibitEscherichia coligrowth. Proliferation was lowest when sodium octanoate was used as the carbon source, followed by acylated ghrelin and desacylated ghrelin. Therefore, the acylated ghrelin found previously in human saliva might help to inhibit pathogenic microorganisms, and acylated ghrelin levels below a critical concentration in saliva could result in an increased risk of oral infection.
