Asymptomatic bacteriuria among the patients of type 2 diabetes mellitus

Background: Asymptomatic bacteriuria (ASB) is common in neonates, preschool children, pregnant women, elderly, diabetics, catheterized patients, and patients with abnormal urinary tracts or renal diseases. Though there is currently no consensus on treatment of ASB in various population groups, it is advisable to treat the same in patients with diabetes mellitus (DM). Aims: To determine the prevalence of ASB in patients with type 2 DM and to study the spectrum of uro-pathogens causing ASB along with their antibiotic susceptibility profile. Settings and Design: This prospective, observational study was conducted in the department of Medicine of a tertiary care teaching hospital. Methods: The study was conducted on 100 patients with type 2 DM. Urine wet mount and gram stain examination was done for all to detect the presence of pus cells and bacteria in urine. Antibiotic sensitivity testing was performed in patients with significant bacteriuria to determine the sensitivity profile of isolated uro-pathogens. The data were analyzed to determine the association between diabetes and ASB. Results: ASB was common among diabetics, as evident by a prevalence of 21%. Presence of ASB showed positive correlation with poor glycemic control. Escherichia coli (E. coli) was the most common organism causing ASB followed by Candida, Pseudomonas, Klebsiella, and Citrobacter. E. coli isolated from study patients was most sensitive to imipenem and nitrofurantoin (NFT). Conclusions: ASB is common among diabetics, with poor glycemic control being a significant risk factor. E. coli is the most common organism causing ASB in diabetics, and it is most sensitive to imipenem and NFT

Where Brain, Body and World Collide

The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pt < 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy sqrt{s} = 7 TeV using an integrated luminosity of 2.2 nb^{-1}. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark-antiquark pairs

Measurement of the Cross Section for Electromagnetic Dissociation with Neutron Emission in Pb-Pb Collisions at √sNN = 2.76 TeV

The first measurement of neutron emission in electromagnetic dissociation of 208Pb nuclei at the LHC is presented. The measurement is performed using the neutron Zero Degree Calorimeters of the ALICE experiment, which detect neutral particles close to beam rapidity. The measured cross sections of single and mutual electromagnetic dissociation of Pb nuclei at √sNN = 2.76 TeV with neutron emission are σ_single EMD = 187.2±0.2 (stat.) +13.8−12.0 (syst.) b and σ_mutual EMD = 6.2 ± 0.1 (stat.) ±0.4 (syst.) b respectively. The experimental results are compared to the predictions from a relativistic electromagnetic dissociation model.The first measurement of neutron emission in electromagnetic dissociation of $^{208}$Pb nuclei at the LHC is presented.

Measurement of charm production at central rapidity in proton-proton collisions at s\sqrt{s} = 2.76 TeV

The pt-differential production cross sections of the prompt (B feed-down subtracted) charmed mesons D0, D+, and D*+ in the rapidity range |y| K- pi+, D+ -> K- pi+ pi+, D*+ -> D0 pi+, and their charge conjugates, and was performed on a L_int = 1.1 nb^-1 event sample collected in 2011 with a minimum-bias trigger. The total charm production cross section at sqrt(s)= 2.76 TeV and at 7 TeV was evaluated by extrapolating to the full phase space the pt-differential production cross sections at sqrt(s) = 2.76 TeV and our previous measurements at sqrt(s) = 7 TeV.

This study aimed to investigate the clinical/biochemical course of kidney transplant patients and its relationship with personality traits in the 3rd, 6th and 9th month after transplantation. Participants were 114 kidney transplant patients, 68 men and 46 women, with an average age of 47.72 years (SD=11.4). Personality was assessed using the Brazilian Factorial Personality Inventory (BFP). Patient charts were used to record clinical/biochemical variables over nine months following transplantation (hypertension, acute rejection, graft loss, death, creatinine and estimated glomerular filtration rate/eGFR). In addition to sociodemographic variables, information was also collected on transfusions prior to transplantation and panel reactive antibodies (HLA I and II).Two groups with personality types were differentiated by psychological characteristics (hierarchical cluster analysis): Cluster 1- average Neuroticism, high Surgency, Agreeableness and Conscientiousness, and low Openness; Cluster 2- high Neuroticism, average Surgency and Agreeableness, average Conscientiousness and low Openness. There was no statistically significant difference between the two clusters in terms of hypertension, acute infection, graft loss, death and HLA I and II panel reactive antibodies. Creatinine levels, eGFR and transfusions were associated with personality types. Cluster 1 contained significantly higher creatinine levels than Cluster 2 and these remained high on all three assessment occasions, with transfusion prior to transplantation less frequent in this group. Cluster 1 exhibited a slight decrease in average eGFR over time, with an increase observed in cluster 2. In individual analyses, Neuroticism was higher in patients with lower schooling levels (p=0.002) and exhibited a significant positive correlation with average eGFR (r=0.250; p=0.008). Agreeableness was significantly higher in men patients (p<0.001) and those without infection (p=0.050). Agreeableness also showed a significant positive correlation with average creatinine levels (r= 0.250; p= 0.007) and a negative association with eGFR (r=-0.208; p=0.027). Higher levels of Conscientiousness were observed in participants with children (p=0.026) not taking medication for depression (p=0.033), as well as a positive correlation with HLA I panel reactive antibodies (r=0.223; p=0.018). In relation to Openness, the only statistically significant difference identified was in relation to schooling, with higher average values found among participants who had completed higher education (p=0.037). The results suggest that personality traits may be associated with transplant results. Monitoring these patients over a longer period may provide a better understanding of the relationship between personality traits and clinical course during the posttransplant period.A rela??o entre personalidade e sa?de tem sido objeto de estudo frequente em pesquisas cient?ficas. Este estudo teve como objetivo principal investigar a evolu??o cl?nica/laboratorial de pacientes transplantados de rim e sua rela??o com tra?os de personalidade no 30, 60 e 90 m?s ap?s o transplante. Participaram do estudo 114 pacientes transplantados renais, 68 homens e 46 mulheres, com idade m?dia de 47,72 anos (DP=11,4). Para a avalia??o da personalidade foi utilizada a Bateria Fatorial de Personalidade (BFP). A partir dos prontu?rios, foram registradas as vari?veis cl?nicas/laboratoriais ao longo de nove meses ap?s o transplante (hipertens?o arterial (HA), rejei??o aguda, infec??o, perda do enxerto, ?bito, creatinina e taxa de filtra??o glomerular estimada/ TFGe). Al?m das vari?veis sociodemogr?ficas, coletaram-se ainda informa??es sobre as transfus?es pr?vias ao transplante e Painel de ant?genos HLA (classe I e II). Dois grupos com perfis de personalidade foram diferenciados pelas caracter?sticas psicol?gicas (an?lise de cluster hierarquizado): Cluster 1- Neuroticismo m?dio, Extrovers?o, Socializa??o e Realiza??o altos e Abertura baixo; Cluster 2- Neuroticismo alto, Extrovers?o, Socializa??o, Realiza??o m?dio e Abertura baixo. Para HA, rejei??o aguda, infec??o, perda do enxerto, ?bito e Painel de ant?genos HLA, classe I e II n?o houve diferen?a estatisticamente significativa entre os dois Clusters. Os n?veis de creatinina, TFGe e transfus?es tiveram associa??o com os perfis de personalidade. Verificou-se que o Cluster 1 concentrou n?veis de creatinina significativamente mais altos que o Cluster 2 e que se mantiveram mais elevados nos tr?s momentos de avalia??o, sendo a transfus?o pr?via ao transplante menos frequente neste grupo. No Cluster 1 ocorreu leve redu??o da m?dia de TFGe ao longo do tempo, enquanto que no Cluster 2 houve aumento. Nas an?lises individuais, Neuroticismo apresentou m?dias mais elevadas nos pacientes com menor escolaridade (p=0,002) e correla??o significativa e positiva com a m?dia de TFGe (r=0,250; p=0,008). O fator Socializa??o apresentou m?dias significativamente mais elevadas nos pacientes homens (p<0,001) e em pacientes sem infe??o (p=0,050). Al?m disto, o fator Socializa??o indicou correla??o significativa positiva com a m?dia de creatinina (r= 0,250; p= 0,007) e negativa com TFGe (r=-0,208; p=0,027). O fator Realiza??o apontou n?veis mais altos nos participantes com filhos (p=0,026) e sem uso de medica??es para depress?o (p=0,033), al?m de correla??o positiva com Reatividade contra painel de ant?genos HLA I (r=0,223; p=0,018). No fator Abertura a ?nica diferen?a estat?stica significativa identificada foi em rela??o ? escolaridade que apontou maiores m?dias nos investigados com Ensino Superior (p=0,037). Os resultados sugerem que as caracter?sticas de personalidade podem estar associadas aos resultados do transplante O acompanhamento destes pacientes durante um per?odo maior poder? levar a um melhor entendimento da rela??o entre fatores de personalidade e evolu??o cl?nica no per?odo p?s-transplante

Multi-strange baryon production in pp collisions at √s=7 TeV with ALICE

A measurement of the multi-strange Ξ− and Ω− baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton–proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (pT) distributions were studied at mid-rapidity (|y|6.0 GeV/c. We also illustrate the difference between the experimental data and model by comparing the corresponding ratios of (Ω−+Ω¯+)/(Ξ−+Ξ¯+) as a function of transverse mass
