PERISTAT: indicators for monitoring and evaluating perinatal health in Europe.

BACKGROUND The PERISTAT project aimed to develop an indicator set for monitoring and describing perinatal health in Europe. The challenge was to define indicators that cover common concerns and have the same meaning within the different European health care systems. METHODS PERISTAT included i) a review of existing recommendations on perinatal health indicators, ii) a DELPHI consensus process with a scientific advisory committee composed of a clinician and an epidemiologist or statistician from each European member state as well as with a panel of midwives, and iii) a study of the availability of national statistics to construct recommended indicators. This article describes the first two components. RESULTS The review identified 10 international and 13 national recommended indicator sets. It also included indicators routinely compiled by WHO, EUROSTAT and OECD. Because of the methodological limits to using existing indicators for European comparisons, a high priority was placed on improving indicators already collected. Using the DELPHI method based on the results of the review, the scientific committee achieved a consensus on ten core and 23 recommended indicators, including 12 requiring further development. CONCLUSIONS The PERISTAT project was successful in identifying a set of indicators, which drew on and consolidated previous work. Consensus was not achieved on precise indicators in areas where uncertainty about appropriate indicators was high, although areas were targeted for future development. Finally, the feasibility study, which is in progress, is an essential part of the project, since it will enable member states to evaluate their capacity to produce these indicators.
An evaluation of fungal enzymes for the solubilization of wheat bran constituents.

Cellulolytic fungi were evaluated for their ability to use wheat bran and produce extracellular enzymes capable of solubilizing carbohydrate and protein fractions from wheat bran. Trichurus cylindricus grew better than all other organisms tested and excreted an extracellular enzyme system which was distinguished by high C1 and Cx cellulase and proteolytic activity. Evidence was also obtained for the existence of a partially extracellular lignolytic enzyme system. The extracellular enzyme system possessed high activity towards wheat bran and the dilute enzyme was able to bring about a 28% weight loss from the insoluble fraction of the wheat bran substrate in 24 h. The extracellular enzyme system from Trichoderma viride and Myrothecium verrucaria were also studied but they were found to be inferior to those of Trichurus cylindricus for the solubilization of wheat bran. However, the crude enzyme preparation from Trichurus cylindricus had a lower activity towards purified cellulose than the enzyme from Tricho.
Flt3L Therapy following Localized Tumor Irradiation Generates Long-Term Protective Immune Response in Metastatic Lung Cancer: Its Implication in Designing a Vaccination Strategy

Flt3 ligand (Flt3L) therapy that expands dendritic cells in vivo in combination with local tumor radiotherapy (RT) significantly improved survival and induced a long-term tumor-specific immune response in a murine model of Lewis lung carcinoma (3LL). The irradiated tumor cells were able to significantly restimulate the splenocytes of the RT + Flt3L cohort in vitro. The restimulated splenocytes demonstrated increased cytotoxic response, lymphocytic proliferation and elevated levels of Th type I cytokines (IL-2, IL-12, IFN-γ and TNF-α). The combination therapy of RT + Flt3L induced a long-term protective immunity in the disease-free animals. The protective effect was further enhanced when the disease-free animals were vaccinated with irradiated tumor cells. The vaccinated animals had significantly greater protection compared to the nonvaccinated group against subsequent challenge with 3LL cells. Taken together, these results indicate that the release of tumor antigens by irradiated dying tumors and concomitant administration of Flt3L was able to facilitate the generation of a tumor-specific long-term immune response against a poorly immunogenic tumor. This effect was further boosted by vaccination with irradiated tumor cells.
Clinical features, diagnostic techniques and management of dual dengue and malaria infection.

OBJECTIVE To find out clinical features, diagnostic techniques and management outcome of patients having dual dengue and malaria infection. STUDY DESIGN A case series. PLACE AND DURATION OF STUDY Medical Unit-III, Ward- 7, Jinnah Postgraduate Medical Centre, Karachi, from September 2007 to January 2008. METHODOLOGY Patients presented with fever of less than or equal to 10 days duration, severe body aches, rash and bleeding manifestations were included. Patients with obvious features of other diseases like typhoid, hereditary bleeding diathesis and hematological malignancies and only malarial parasite positive with high grade intermittent fever without rash and myalgia were excluded from the study. Diagnosis of dengue and malaria was based on history, clinical features, laboratory parameters and malarial parasite test by thin and thick films. Serological evaluation was done by dengue IgM and IgG by ELISA test kit. Patients were divided into three groups. Group A was dengue IgM positive plus MP positive, group B was dengue IgM positive and MP negative and group C was dengue IgM negative and MP negative and were clinically suspected dengue and malaria. The clinical manifestations and laboratory parameters of dual dengue and malaria positive patients were compared with malaria and dengue negative patients. RESULTS One hundred and fourteen patients were seen during the study period. Antibody titer (IgM) tested in all patients was found positive in 78 patients (69.64%). Among those 78 patients, 26 (23.21%) were concomitantly positive for malarial parasite (Group A). Plasmodium vivax was positive in 25 patients and falciparum in one patient. Fifty-two patients (46.42%) were dengue IgM positive and MP negative (Group B). Thirty four (30.35%) patients were MP and dengue IgM negative (Group C) but were strongly suspected for DHF and malaria on clinical and hematological basis. The hemoglobin of 34.61% of patients of group A, 5.76% of group B and 14.7% of group C were low, hematocrit level was also low in group A (92.3%), group B (15.38%) and group C (70.58%) patients. The platelet count was markedly low in 84.61% of patients of group A, 57.69% of group B and 94.11% of group C. Leukopenia was found in 34.61% of patients of group A, 78.84% in group B and 29.411% in group C. The liver function tests were deranged in all groups. CONCLUSION The frequency of dual dengue and malaria infection was 23.21%. The serology of the dengue and malaria showed negative results in 30.35%. The diagnosis of dual infections could be made on the basis of history, clinical examination supported by hematological results. It is recommended that all the patients suspected for dual infections should be treated concomitantly for dengue and malaria in malaria endemic areas.
An Algorithm for Convex Quadratic Programming That Requires O(n3.5L) Arithmetic Operations

A new interior point method for minimizing a convex quadratic function over a polytope is developed. We show that our method requires O ( n 3.5 L ) arithmetic operations. In our algorithm we construct a sequence P z 0 , P z 1 , …, P z k , … of nested convex sets that shrink towards the set of optimal solution(s). During iteration k we take a partial Newton step to move from an approximate analytic center of P z k − 1 to an approximate analytic center of P z k . A system of linear equations is solved at each iteration to find the step direction. The solution that is available after O (√ mL ) iterations can be converted to an optimal solution. Our analysis indicates that inexact solutions to the linear system of equations could be used in implementing this algorithm.
Phylogenetic Analysis of Enteroaggregative and Diffusely Adherent Escherichia coli

ABSTRACT The phylogenetics of the various pathotypes of diarrheagenicEscherichia coli are not completely understood. In this study, we identified several plasmid and chromosomal genes in the pathogenic enteroaggregative E. coli (EAEC) prototype strain 042 and determined the prevalence of these loci among EAEC and diffusely adherent E. coli strains. The distribution of these genes is analyzed within an evolutionary framework provided by the characterization of allelic variation in housekeeping genes via multilocus enzyme electrophoresis. Our data reveal that EAEC strains are heterogeneous with respect to chromosomal and plasmid-borne genes but that the majority harbor a member of a conserved family of virulence plasmids. Comparison of plasmid and chromosomal relatedness of strains suggests clonality of chromosomal markers and a limited transfer model of plasmid distribution.
Effect of different simulated altitudes on repeat-sprint performance in team-sport athletes.

PURPOSE This study aimed to assess the impact of 3 heights of simulated altitude exposure on repeat-sprint performance in team-sport athletes. METHODS Ten trained male team-sport athletes completed 3 sets of repeated sprints (9 × 4 s) on a nonmotorized treadmill at sea level and at simulated altitudes of 2000, 3000, and 4000 m. Participants completed 4 trials in a random order over 4 wk, with mean power output (MPO), peak power output (PPO), blood lactate concentration (Bla), and oxygen saturation (SaO2) recorded after each set. RESULTS Each increase in simulated altitude corresponded with a significant decrease in SaO2. Total work across all sets was highest at sea level and correspondingly lower at each successive altitude (P < .05; sea level < 2000 m < 3000 m < 4000 m). In the first set, MPO was reduced only at 4000 m, but for subsequent sets, decreases in MPO were observed at all altitudes (P < .05; 2000 m < 3000 m < 4000 m). PPO was maintained in all sets except for set 3 at 4000 m (P < .05; vs sea level and 2000 m). BLa levels were highest at 4000 m and significantly greater (P < .05) than at sea level after all sets. CONCLUSIONS These results suggest that "higher may not be better," as a simulated altitude of 4000 m may potentially blunt absolute training quality. Therefore, it is recommended that a moderate simulated altitude (2000-3000 m) be employed when implementing intermittent hypoxic repeat-sprint training for team-sport athletes.
Bulk damage effects in irradiated silicon detectors due to clustered divacancies

High resistivity silicon particle detectors will be used extensively in experiments at the future CERN Large Hadron Collider. The detectors will be exposed to particle fluences equivalent to ∼1014 (1 MeV neutrons)/cm2, causing significant atomic displacement damage. A model has been developed to estimate the evolution of defect concentrations and the electrical behavior of irradiated silicon detectors using Shockley–Read–Hall (SRH) semiconductor statistics. The observed increases in leakage current and doping concentration changes can be described well after 60Co-gamma irradiation but less well after fast neutron irradiation. A possible non-SRH mechanism is considered, based on the hypothesis of charge transfer between clustered divacancy defects in neutron damaged silicon detectors. This leads to a large enhancement over the SRH prediction for V2 acceptor state occupancy and carrier generation rate which may resolve the discrepancy between the model and neutron damage data.
Lack of Efficacy of 2-Chlorodeoxyadenoside in the Treatment of Splenic Lymphoma with Villous Lymphocytes

Splenic lymphoma with villous lymphocytes (SLVL) is a B-cell chronic lymphoproliferative disorder. Splenectomy and/or chlorambucil (CLB) are usually regarded as the most effective treatment in SLVL patients. However, a few patients relapse and the second line therapy remains questionable. Although 2-Cda has been evaluated in patients with chronic lymphoid leukemia (CLL) and hairy cell leukemia (HCL), it has been reported as the treatment of SLVL in only one case report. Therefore, we have evaluated its efficacy and toxicity in 7 SLVL patients. The median duration between diagnosis and treatment was 18 months (range, 1 to 59). The patients received 2-CdA (0.1 mg/kg/d) by venous infusion for 7 days with a median number of 1 cycle (range, 1 to 2) either as a first line therapy (one patient) or after a failure of other therapies (splenectomy, chemotherapy). Two patients achieved a complete response. The first one maintained his CR during a follow-up of 9 months and then relapsed; the second patient remained in CR after a follow-up of 20 months. Four patients achieved a partial response and relapsed after a median follow-up of 3.5 months (range, 1 to 4). One patient had no response. The treatment was not well tolerated with many infectious events. In the limits of our study, 2-Cda does not appear to be efficient therapy for SLVL and is not well tolerated for patients in relapse after splenectomy or resistant to CLB.
Bacterial Interaction with Graphene Particles and Surfaces

Research into the properties and uses of graphene has rapidly expanded over the past decade. Indeed, prior to the seminal paper by Geim and Novoselov in 2004 [1] which eventually led to the 2009 Nobel Prize for physics, the potential of this material was relatively underappre‐ ciated. Graphene is a monolayer thick, two dimensional form of carbon atoms linked together in a hexagonal lattice. The sp2 hybridisation of all bonds across the sheet gives rise to its interesting and unique, physical, mechanical, thermal and electrical properties. Thus graphene can be considered to be a 2 dimensional form of its analogue graphite [2]. Importantly, the properties of graphene vary significantly to the bulk material graphite, particularly in terms of electron mobility, and these significant feature differences have driven research in fields as diverse as electronics, materials, energy, defence, security, water and health [3, 4].
Perinatal mortality rates in isolated general practitioner maternity units.

OBJECTIVE--To determine the perinatal mortality rate among normally formed, singleton babies with birth weights greater than or equal to 2500 g in Bath health district based on the intended place of delivery at the time of onset of labour or at the time of diagnosis of intrauterine death. DESIGN--The numbers of live births and stillbirths were collected monthly returns from the maternity units concerned. Deaths of infants aged less than or equal to 1 week were collected in the same returns. The intended place of delivery was confirmed at the monthly perinatal mortality meeting, during which maternal and fetal factors were discussed. SETTING--A rural health district of 400,000 population where one third of all deliveries occurred in seven isolated general practitioner maternity units, 8% in the integrated general practitioner unit, and the remainder in the consultant unit. SUBJECTS--All babies of women whose deliveries were booked in the district before the onset of labour or the diagnosis of intrauterine death, excluding twins, babies with lethal congenital malformations, and those less than 2500 g. MAIN OUTCOME MEASURES--Outcome of all deliveries and parity of mothers. RESULTS--14,415 Deliveries were analysed. The perinatal mortality rate was 2.8/1000 births in the consultant unit (7950 deliveries), 4.8 in the isolated general practitioner units (5237 deliveries), and zero in the integrated general practitioner unit (1228 deliveries). Perinatal deaths attributable to asphyxia were more common in the isolated general practitioner units (1.5 per 1000) than the consultant unit (0.6 per 1000). The perinatal mortality rate among babies born to nulliparous women was 3.2/1000 births in the consultant unit and 5.7 in the isolated general practitioner units; for those born to multigravid women it was 2.4 and 4.2 respectively. CONCLUSIONS--The outcome of delivery was not influenced by parity. Both antenatal and intrapartum care were responsible for the higher perinatal mortality rate in the isolated general practitioner units. The integrated unit, which shared midwifery staff with the consultant unit, seemed to work well. Analysis by intended place of delivery at the time of onset of labour or diagnosis of intrauterine death suggested that the care given in isolated units needs to be improved, perhaps by better training of general practitioners and consultant supervision of antenatal care.
Magnetic navigation facilitates percutaneous coronary intervention for complex lesions

We sought to determine the utility of a magnetic navigation system (MNS) in treating a variety of coronary artery lesions including those that could not be revascularized with standard percutaneous coronary intervention (PCI). MNS may add value in the treatment of tortuous arteries and bifurcation lesions; however its widespread adoption has lagged because of cost and a lack of clear advantage over conventional PCI. We performed a retrospective analysis to determine whether MNS improved procedural success for highly complex lesions.
New Roles for Mononuclear Phagocytes in Cancer Biology

The primary focus in the pathogenesis and treatment of human malignancies has been the tumor cell. However, the biologic properties of a malignancy are not all intrinsically determined. Interactions between heterogeneous cell populations influence the growth and survival of both normal and malignant cells. Studies defining the origin of endothelial cells involved in tumor angiogenesis first demonstrated the contributions of normal cellular environment. Recently, the mononuclear phagocyte lineage has been found to have biologically and clinically significant tumor enhancing and tumor suppressive effects. This article reviews the multiple roles of mononuclear phagocytes in cancer biology. A companion manuscript (J Pediatr Hematol Oncol. 2008, in press) describes the targeting of these cells for therapeutic benefit. Incorporating these strategies into future childhood cancer protocols could be an innovative approach for improving patient outcome.
Activation of protein kinase C augments T‐type Ca2+ channel activity without changing channel surface density

T‐type Ca2+ channels play essential roles in numerous cellular processes. Recently, we reported that phorbol‐12‐myristate‐13‐acetate (PMA) potently enhanced the current amplitude of Cav3.2 T‐type channels reconstituted in Xenopus oocytes. Here, we have compared PMA modulation of the activities of Cav3.1, Cav3.2 and Cav3.3 channels, and have investigated the underlying mechanism. PMA augmented the current amplitudes of the three T‐type channel isoforms, but the fold stimulations and time courses differed. The augmentation effects were not mimicked by 4α‐PMA, an inactive stereoisomer of PMA, but were abolished by preincubation with protein kinase C (PKC) inhibitors, indicating that PMA augmented T‐type channel currents via activation of oocyte PKC. The stimulation effect on Cav3.1 channel activity by PKC was mimicked by endothelin when endothelin receptor type A was coexpressed with Cav3.1 in the Xenopus oocyte system. Pharmacological studies combined with fluorescence imaging revealed that the surface density of Cav3.1 T‐type channels was not significantly changed by activation of PKC. The PKC effect on Cav3.1 was localized to the cytoplasmic II–III loop using chimeric channels with individual cytoplasmic loops of Cav3.1 replaced by those of Cav2.1.
Point of View

In this article, the authors evaluated the potential benefit of using a clinical diagram derived from a decision tree to help various reviewers classify adolescent idiopathic scoliosis cases via the Lenke system. They compared classification accuracy and speed using the original Lenke chart alone versus the decision tree algorithm. They found that when the reviewers used this decision tree, both classification accuracy and speed statistically improved. This was true for both nonexperts including various level residents and an engineer, as well as experts, which included 3 practicing orthopedic pediatric spinal deformity surgeons, 2 residents (undergoing graduate studies on AIS related topics), and 1 senior nurse scoliosis clinician. Interestingly, without the decision tree, the average classification accuracy was 86.3% for the experts versus 68.0% for the nonexperts. However, with the decision tree, the results were almost identical at 93.1% for the experts versus 92.8% for the nonexperts. Although not identical, this was very similar to the interobserver reliability of 93% found from the developers of the classification system as reported in 2001. The fact that a clinical algorithm increased classification accuracy was also similar to what Stokes et al found in using a computer-assisted algorithm to improve the reliability of the King Classification. One must remember that this study only evaluated the curve type, not the complete classification as they excluded the lumbar modifier and sagittal modifier. It would be interesting to know whether a similar type of decision tree could optimize accuracy of those components of the classification system as well. However, this straight forward study did show the benefit of a seemingly easy to use clinical algorithm in attaining the correct curve type of operative AIS patients in 93% of cases for a variety of different reviewers. Knowing that computer programs are certainly being used to reliably obtain the Lenke Classification System from digitized radiographs, it is not too surprising that a similar clinicaltype decision tree would accomplish a higher percent classification by its structured analysis as assessed by various reviewers. I congratulate the authors on this simple, straight forward, and valuable study to improve AIS curve classification.
On the limits of applicability of drift-diffusion based hot carrier degradation modeling

We study the limits of the applicability of a drift-diffusion (DD) based model for hot-carrier degradation (HCD). In this approach the rigorous but computationally expensive solution of the Boltzmann transport equation is replaced by an analytic expression for the carrier energy distribution function. On the one hand, we already showed that the simplified version of our HCD model is quite successful for LDMOS devices. On the other hand, hot carrier degradation models based on the drift-diffusion and energy transport schemes were shown to fail for planar MOSFETs with gate lengths of 0.5–2.0 µm. To investigate the limits of validity of the DD-based HCD model, we use planar nMOSFETs of an identical topology but with different gate lengths of 2.0, 1.5, and 1.0 µm. We show that, although the model is able to adequately represent the linear and saturation drain current changes in the 2.0 µm transistor, it starts to fail for gate lengths shorter than 1.5 µm and becomes completely inadequate for the 1.0 µm device.
