Spectrum of uropathogens and their antibiotic sensitivity pattern in diabetes mellitus patients at a tertiary care hospital in Odisha, India

Background: Diabetes Mellitus is the most common endocrine disorder involving almost all systems of body. Untreated or poorly treated Diabetics are susceptible to develop a series of complications responsible for raised morbidity and mortality. Diabetes Mellitus has a number of long term effects on the Genitourinary system. Urinary tract infections have long been recognised as a significant problem in patients with Diabetes Mellitus.Methods: Prospective observational study. Diabetic patients with culture positive UTI were included. Gestational diabetes, Immunocompromised patients and patients with congenital renal anatomical abnormalities were excluded.Results: Authors included 211 numbers of culture positive UTI among diabetic patients. Out of which, 65 were male and 146 were female. Maximum number of patients belong to 56-65 years age group. Escherichia coli was the predominant organism isolated. Gram positive organisms showed 100% sensitivity to Vancomycin and Linezolid. Gram negative organisms showed 100% sensitivity to Polymyxin B.Conclusions: Genitourinary tract infection is not an infrequent complication seen in diabetes patients. Most common causative organism and their antibiotic sensitivity pattern should be done in tertiary care hospital for a better antibiotic policy

Clinical profile and outcome of organ dysfunction in sepsis

Background: Sepsis is defined as life threatening organ dysfunction due to a dysregulated host response to infection. It is the tenth leading cause of death among older adults in United States. Mortality rate of the sepsis ranges from 30-40%. In severe cases sepsis can drastically reduce blood flow to the major organs, leading eventually to septic shock, widespread organ failure and death. So, the present study was done to evaluate the clinical profile, symptoms, source of infection, co-morbid conditions and outcome with respect to the organ dysfunction in sepsis cases.Methods: This prospective observational study was undertaken among 100 cases of sepsis diagnosed by the “International Sepsis Definitions Conference” criteria admitted during October 2015 to September 2017. All patients were evaluated clinically and subjected for laboratory investigations.Results: In present study, a total of 100 cases were enrolled. Mean age of cases were 38.15 years. Male and female ratio was 1.63:1. Most common symptom was fever (100%). Pneumonia was the most common (36%) source of infection. Mortality was highest in pneumonia (55.55%). 77 % of cases had organ dysfunction. Cardiovascular system was the most common system involved. Maximum mortality was within the age group of 56-65 years. Diabetes was the most common co-morbid condition. Mean APACHE II score was high among the death cases.Conclusions: Sepsis was more common in younger group of patients but mortality was more in elderly age group. Overall mortality was 38%.

Study of serum homocysteine level in cases of non-diabetic ischemic stroke

Background: Aim of the study was to measure serum homocysteine levels in non-diabetic ischemic stroke and to co-relate its significance with other risk factors of ischemic stroke. It was a case control study.Methods: The study was done in the Department of Medicine, VSS.I.M.S.A.R, Burla, Odisha. 42 patients of non-diabetic ischemic and 42 age and sex matched controls were included in the study. Adults above the age of 18 years who were non-diabetic presenting with first-ever ischemic stroke, confirmed by CT scan of brain were included. Diabetic patients, haemorrhagic stroke, suspected embolic stroke, patients on vitamin supplementations, chronic usage of phenytoin were excluded. Routine investigations, fasting serum lipid profile and serum homocysteine levels were done.Results: Mean serum homocysteine level in ischemic stroke patients were found to be much higher (25.83 micro mol/L) in comparison to control group (9.77 micro mol/L) which is statistically significant. Mean serum homocysteine levels were found to be higher in patients with age group of more than 60 years, male sex, sedentary lifestyle, vegetarian diet, hypertensive patients and patient with normal fasting lipid profile. Statistical analysis for significance of difference was done using Chi-Square test with Yate’s correction.Conclusions: A statistically significant correlation was found between all the studied risk factors among non-diabetic patients and serum homocysteine levels. Estimation of serum homocysteine is advisable in all cases of non-diabetic ischemic strokes to know the prognosis

A nonlocal sinusoidal shear deformation beam theory with application to bending, buckling, and vibration of nanobeams

This paper presents a nonlocal sinusoidal shear deformation beam theory for the bending, buckling, and vibration of nanobeams. The present model is capable of capturing both small scale effect and transverse shear deformation effects of nanobeams, and does not require shear correction factors. Based on the nonlocal differential constitutive relations of Eringen, the equations of motion as well as the boundary conditions of the beam are derived using Hamilton’s principle. Analytical solutions for the deflection, buckling load, and natural frequency are presented for a simply supported beam, and the obtained results are compared with those predicted by the nonlocal Timoshenko beam theory. The comparison firmly establishes that the present beam theory can accurately predict the bending, buckling, and vibration responses of short nanobeams where the small scale and transverse shear deformation effects are significant

Revisiting the [C ii]158��m line-intensity mapping power spectrum from the EoR using non-uniform line-luminosity scatter

Detecting the line-intensity mapping (LIM) signal from the galaxies of the Epoch of Reionization is an emerging tool to constrain their role in reionization. Ongoing and upcoming experiments target the signal fluctuations across the sky to reveal statistical and astrophysical properties of these galaxies via signal statistics, e.g., the power spectrum. Here, we revisit the [Cii]158m LIM power spectrum under non-uniform line-luminosity scatter, which has a halo-mass variation of statistical properties. Line-luminosity scatter from a cosmological hydrodynamic and radiative transfer simulation of galaxies at = 6 is considered in this study. We test the robustness of different model frameworks that interpret the impact of the line-luminosity scatter on the signal statistics. We use a simple power-law model to fit the scatter and demonstrate that the mean luminosity-halo mass correlation fit cannot preserve the mean intensity of the LIM signal (hence the clustering power spectrum) under non-uniform scatter. In our case, the mean intensity changes by ∼ 48 per cent compared to the mean correlation fit in contrast to the general case with semianalytic scatter. However, we find that the prediction for the mean intensity from the most-probable fit can be modelled robustly, considering the generalized and more realistic non-uniform scatter. We also explore the possibility of diminishing luminosity bias under non-uniform scatter, affecting the clustering power spectrum, although this phenomenon might not be statistically significant. Therefore, we should adopt appropriate approaches that can consistently interpret the LIM power spectrum from observations

Clinico-laboratory profile of dengue patients in a tertiary hospital of Eastern India

Background: Dengue is the most rapidly spreading mosquito-borne viral disease of mankind. According to WHO, about 50-100 million new dengue infections are estimated to occur annually in more than 100 endemic countries.So, the present study has been done to analyzed varied clinical and laboratory profile of confirm dengue cases.Methods: Cross-sectional observational study was undertaken among 106 adult Ig M Ab positive cases admitted during October 2015 to September 2017. All patients were evaluated clinically and subjected for relevant laboratory investigations.Results: In our study male and female ratio was 20.2:1. Most common symptom was fever (95.3%) and least common was jaundice. Second most symptom was headache (70.8%). Myalgia was present in 49.1% of cases. 54.7% had nausea/vomiting. Hypotension was noticed in 33% of cases whereas encephalopathy and melaena was found in 6.6% and 2.83% respectively. Leucopenia was present in 57.5% and thrombocytopenia in 50.9% of cases.Conclusions: Younger male were commonly affected with dengue fever and promptly responded to conservative therapy due to early confirmation of diagnosis. Mortality was only 1.8% cases, may be due to delay in seeking medical attention

Intense violet–blue emission and paramagnetism of nanocrystalline Gd3+ doped ZnO ceramics

Nanocrystalline Zn1-xGdxO (x = 0, 0.02, 0.04, 0.06, and 0.08) ceramics were synthesized by ball milling and subsequent solid-state reaction. The transmission electron microscopy (TEM) micrograph of as synthesized samples revealed the formation of crystallites with an average diameter of 60 nm, and the selected area electron diffraction (SAED) pattern confirmed the formation of wurtzite structure. A red shift in the band gap was observed with increasing Gd3+ concentration. The photoluminescence of nanocrystalline Gd3+ doped ZnO exhibited a strong violet–blue emission. Concentration dependence of the emission intensity of Gd3+ in ZnO was studied, and the critical concentration was found to be 4 mol% of Gd3+. The Gd3+ doped ZnO exhibited paramagnetic behavior at room temperature, and the magnetic moment increased with Gd3+ concentration

Prenatal stress and subsequent exposure to chronic mild stress influence dendritic spine density and morphology in the rat medial prefrontal cortex

<p>Abstract</p> <p>Background</p> <p>Both prenatal stress (PS) and postnatal chronic mild stress (CMS) are associated with behavioral and mood disturbances in humans and rodents. The aim of this study was to reveal putative PS- and/or CMS-related changes in basal spine morphology and density of pyramidal neurons in the rat medial prefrontal cortex (mPFC).</p> <p>Results</p> <p>We show that rats exposed to PS and/or CMS display changes in the morphology and number of basal spines on pyramidal neurons in the mPFC. CMS had a negative effect on spine densities, particularly on spines of the mushroom type, which are considered to form stronger and more stable synapses than other spine types. PS alone did not affect spine densities, but had a negative effect on the ratio of mushroom spines. In addition, PS seemed to make rats less responsive to some of the negative effects of CMS, which supports the notion that PS represents a predictive adaptive response.</p> <p>Conclusion</p> <p>The observed changes may represent a morphological basis of PS- and CMS-related disturbances, and future studies in the field should not only consider total spine densities, but also separate between different spine types.</p
