Comparative study of serum electrolytes Na+, K+, Ca++ in patients of chronic kidney disease in relation to its severity

Background: Chronic kidney disease (CKD) is a worldwide public health problem. Globally, CKD is the 12th cause of death and the 17th cause of disability, respectively. Yearly incidence of ESRD in India is approximately 150-200 pmp.Methods: The observational study was conducted in Department of General Medicine, Pandit Raghunath Murmu Medical College Hospital, Baripada between May 2018 and January 2019. 244 patients of Chronic Kidney Disease above 15 years of age satisfying the inclusion and exclusion criteria were included in the study.Results: Study group constitutes 64.34% (157) of male and 35.66% (87) of female patients with M:F of 1.8:1. The average age of the patients in the study was 55.91±12.49 yrs. 42.21% (103) of the patients were between 46 and 60 years of age. Maximum number of cases (190 cases) (77.87%) are in stage 4 and 5 with e-GFR <30 ml/ min. The average serum electrolytes in this study group for serum sodium, potassium, calcium are 137.31±10.05 mEq/L, 4.12±1.48 mEq/L and 1.10±0.19 mmol/L respectively. When association of hypokalemia with risk factor (known and unknown) is compared, chi-square value found to be 13.664 (p=0.0002) which is statistically extremely significant.Conclusions: Authors found significant number of cases, more commonly younger patients, presented with atypical manifestations having no specific etiology; the cause may be defect in rennin-angiotensin system or, may be genetic or, may be environmental

Use of iodine tincture in the management of wound dehiscence in operated mandibular fracture along with hardware salvage: a case report

Mandibular fractures are one of the most common facial fractures. Depending on the severity, they are treated either by closed reduction or open reduction and internal fixation. Hardware exposure is one of the postoperative complications associated with the latter. Data involving decision regarding removal or salvage of hardware in such cases is lacking. We present a case of wound dehiscence with hardware exposure in an operated mandibular fracture, which was managed by placing tincture iodine dressing, thus obviating the need for hardware removal

Production and optimization of mevastatin by Penicillium citrinum MTCC 1256 and effect of citrinin on growth of Actinomadura strains

The aim of the present research was to study the optimisation of mevastatin production by Penicillium citrinum MTCC 1256. Optimization of fermentation medium was carried out by response surface methodology. Simultaneous estimation of mevastatin and citrinin was carried out by high performance thin layer chromatography. Glycerol and peptone were shown to be the best carbon and nitrogen source for mevastatin production by P. citrinum. Under optimized culture medium containing glycerol 10.94 g.l-1 , peptone 8.32 g.l-1 , CaCl2 0.53 g.l-1 , MgSO4 0.52 g.l-1 and KH2PO4 0.049 g.l-1 resulted in a maximal mevastatin production of 522.5 mg.l-1 Growth inhibited effect of citrinin on actinomycetes was . measured in terms of colony forming unit (CFU). There is a decrease in CFU of Actinomadura madura and Actinomadura livida with the increase in citrinin concentration. In terms of citrinin production, an 8-day fermentation would be preferable to a 14-day period, for the eventual bioconversion of mevastatin to pravastatin, since under these conditions spent broth would be free of this inhibitory product.Colegio de Farmacéuticos de la Provincia de Buenos Aire

New 2-chloro-7-methylquinoline amine analogues as possible antimycotic agents

A series of N-[(2-chloro-7-methylquinolin-3-yl)methyl]-(substituted)-aniline/butan-1-amine/cyclohexamine derivatives (4a-n) & N-benzyl-1-(2-chloro-7-methylquinolin-3-yl)methanamine (4o) was designed and synthesized based on the structural requirements essential for allylamine / benzylamine antimycotics. Compounds (4a-o) were synthesized by nucleophilic substitution reaction of 2-chloro-3-(chloromethyl)-7- methylquinoline with substituted aromatic/aliphatic primary amine in absolute ethanol in presence of triethylamine. The structures of all new products were confirmed by IR, 1H & 13C-NMR and mass spectral data. The newly synthesized compounds were screened in-vitro for their antifungal activity against Aspergillus niger MTCC 281, Aspergillus flavus MTCC 277, Monascus purpureus MTCC 369 and Penicillium citrinum NCIM 768 by cup plate method. Preliminary screening of compounds (4a-o) revealed that compounds viz. 4a, 4b, 4e, 4g, 4j and 4l showed excellent antifungal activity. Dihalogen and benzyl substituted compounds 4j, 4l & 4o exhibited potent antifungal activity. Replacement of phenyl ring with aliphatic groups like butyl or cyclohexyl causes substantial decrease in antifungal activity and activity decreases when phenyl ring is substituted with electron releasing groups.Colegio de Farmacéuticos de la Provincia de Buenos Aire

An MLL-Dependent Network Sustains Hematopoiesis

The histone methyltransferase Mixed Lineage Leukemia (MLL) is essential to maintain hematopoietic stem cells and is a leukemia protooncogene. Although clustered homeobox genes are well-characterized targets of MLL and MLL fusion oncoproteins, the range of Mll-regulated genes in normal hematopoietic cells remains unknown. Here, we identify and characterize part of the Mll-dependent transcriptional network in hematopoietic stem cells with an integrated approach by using conditional loss-of-function models, genomewide expression analyses, chromatin immunoprecipitation, and functional rescue assays. The Mll-dependent transcriptional network extends well beyond the previously appreciated Hox targets, is comprised of many characterized regulators of self-renewal, and contains target genes that are both dependent and independent of the MLL cofactor, Menin. Interestingly, PR-domain containing 16 emerged as a target gene that is uniquely effective at partially rescuing Mll-deficient hematopoietic stem and progenitor cells. This work highlights the tissue-specific nature of regulatory networks under the control of MLL/Trithorax family members and provides insight into the distinctions between the participation of MLL in normal hematopoiesis and in leukemia

Investigation of mechanical properties of silver-doped diamond-like carbon coating by varying deposition temperature

The present work shows the influence of deposition temperatures on the mechanical properties of silver (Ag)-doped diamond-like carbon (DLC) coating synthesized by the thermal chemical vapor deposition (CVD) technique. The deposited film showed excellent mechanical and tribological behavior with respect to the lower deposition temperatures. From the EDS analysis, it was confirmed that the percentage of Ag decreased from 9.8% to 8.4% as the deposition temperature increased. The nanoindentation tests at different loads were extensively carried out to observe the mechanical properties of the coating with respect to various deposition temperatures. The coating hardness (H) and Young’s modulus (E) decreased with the rise in furnace temperature, and the Hmax. and Emax. were observed as 29.71 and 251.19 GPa, respectively, for the Ag-DLC coating grown at 800°C at a load of 20 mN. In comparison to other Ag-DLC thin films made using different deposition techniques, the residual stress (σ) was significantly reduced, reaching 0.45 GPa, which is extremely low

The Australasian Resuscitation In Sepsis Evaluation : fluids or vasopressors in emergency department sepsis (ARISE FLUIDS), a multi-centre observational study describing current practice in Australia and New Zealand

Objectives: To describe haemodynamic resuscitation practices in ED patients with suspected sepsis and hypotension. Methods: This was a prospective, multicentre, observational study conducted in 70 hospitals in Australia and New Zealand between September 2018 and January 2019. Consecutive adults presenting to the ED during a 30-day period at each site, with suspected sepsis and hypotension (systolic blood pressure <100 mmHg) despite at least 1000 mL fluid resuscitation, were eligible. Data included baseline demographics, clinical and laboratory variables and intravenous fluid volume administered, vasopressor administration at baseline and 6- and 24-h post-enrolment, time to antimicrobial administration, intensive care admission, organ support and in-hospital mortality. Results: A total of 4477 patients were screened and 591 were included with a mean (standard deviation) age of 62 (19) years, Acute Physiology and Chronic Health Evaluation II score 15.2 (6.6) and a median (interquartile range) systolic blood pressure of 94 mmHg (87–100). Median time to first intravenous antimicrobials was 77 min (42–148). A vasopressor infusion was commenced within 24 h in 177 (30.2%) patients, with noradrenaline the most frequently used (n = 138, 78%). A median of 2000 mL (1500–3000) of intravenous fluids was administered prior to commencing vasopressors. The total volume of fluid administered from pre-enrolment to 24 h was 4200 mL (3000–5661), with a range from 1000 to 12 200 mL. Two hundred and eighteen patients (37.1%) were admitted to an intensive care unit. Overall in-hospital mortality was 6.2% (95% confidence interval 4.4–8.5%). Conclusion: Current resuscitation practice in patients with sepsis and hypotension varies widely and occupies the spectrum between a restricted volume/earlier vasopressor and liberal fluid/later vasopressor strategy
