Article Synopsis
  • The study focused on evaluating antimicrobial resistance (AMR) patterns in ICU patients across multiple tertiary care centers in India, highlighting the variability of resistance over time and geography.
  • Utilizing data from 21,556 samples collected over about a decade, researchers analyzed microbial isolates and their antibiotic susceptibility based on established guidelines.
  • Results indicated that the majority of infected patients were adult males, with Staphylococcus aureus being the most prevalent bacteria, showing significant resistance to common antibiotics like ciprofloxacin and erythromycin.

Two-dimensional transition metal dichalcogenides (TMDs) have drawn immense interest due to their strong spin-orbit coupling and unique layer number dependence in response to spin-valley coupling. This leads to the possibility of controlling the spin degree of freedom of the ferromagnet (FM) in thin film heterostructures and may prove to be of interest for next-generation spin-based devices. Here, we experimentally demonstrate the odd-even layer dependence of WS nanolayers by measurements of the ultrafast magnetization dynamics in WS/CoFeB thin film heterostructures by using time-resolved Kerr magnetometry.

Cytomegalovirus (CMV) reactivation may be a cause of acute exacerbations in patients with severe ulcerative colitis (UC). Patients with exacerbation of symptoms by CMV have greater morbidity and mortality rate. The present study was conducted to evaluate the prevalence of CMV infection in UC patients by endoscopic examination, histopathological examination and CMV DNA PCR of colonic mucosal biopsy tissue and also to identify the associated risk factors and clinical outcomes.

is a plant fungus causing silver leaf disease of plants, particularly of the rose family. Here we report a case of paratracheal abscess caused by This is a first of its kind of a case wherein this plant fungus caused disease in a human. Conventional techniques (microscopy and culture) failed to identify the fungus.

The use of cardiovascular implantable electronic devices (CIED) is associated with improved quality of life and decreased fatal outcomes in patients with cardiac dysfunctions. As with all foreign devices that are inserted or implanted in the body, CIED also carries the risk of device-related infections. Infections account for <2% of the complications associated with CIED, and only about 2% of these are secondary to a fungal pathogen.

We show how sintering in different atmospheres affects the structural, microstructural, and functional properties of ~30 μm thick films of KNaNbO (KNN) modified with 0.38 mol% KCuTaO and 1 mol% CuO. The films were screen printed on platinized alumina substrates and sintered at 1100 °C in oxygen or in air with or without the packing powder (PP).

Pure spin current has transformed the research field of conventional spintronics due to its various advantages, including energy efficiency. An efficient mechanism for generation of pure spin current is spin pumping, and high effective spin-mixing conductance () and interfacial spin transparency () are essential for its higher efficiency. By employing the time-resolved magneto-optical Kerr effect technique, we report here a giant value of in substrate/W ()/CoFeB ()/SiO (2 nm) thin-film heterostructures in the beta-tungsten (β-W) phase.

Six new binary charge-transfer (CT) cocrystals have been synthesized by solvent drop-assisted mechanochemical grinding method, and all of them exhibited remarkable color changes during the grinding process. Crystal structure analysis reveals the donor (D) and acceptor (A) molecules have assembled primarily via cofacial π···π stacking interactions displaying mixed D-A-D-A stacked columns. Interestingly these cocrystals exhibited very diverse dielectric response in the presence of an alternating current (ac) external electric field, and their dielectric behavior can be explained from the nature and strength of CT interactions in the cocrystal assembly.

Unlabelled: Nonalcoholic fatty liver disease (NAFLD) and its progressive form nonalcoholic steatohepatitis (NASH) are a growing problem globally and recur even after liver transplant (LT). We aim to characterize the gut dysbiosis in patients who developed recurrent NAFLD compared with patients without recurrence following LT.

Methods: Twenty-one patients who received LT for NASH and had a protocol liver biopsy performed beyond 1-y post-LT were included prospectively (January 2018-December 2018).

Mammalian Sphingosine kinase 2 is the primary enzyme responsible for phosphorylating FTY720 to its active form, FTY720-P. Systemic FTY720 treatment confers significant protection to murine retinas from light- and disease-mediated photoreceptor cell death. It is not clear whether FTY720-P, FTY720, or both are responsible for this photoreceptor protection.

Introduction of rough sets by Professor Zdzisław Pawlak has completed 35 years. The theory has already attracted the attention of many researchers and practitioners, who have contributed essentially to its development, from all over the world. The methods, developed based on rough set theory alone or in combination with other approaches, found applications in many areas.

The present study illustrates the optimization and characterization of β-glucosidase from a bacterial isolate, strain SG9. Sixty-eight different variables were first screened by one factor at a time method. The screened variable optimization was then performed by Plackett-Burman design followed by Box-Behnken response surface methodology.

Context: Ventilator-associated tracheobronchitis (VAT) is an infective complication of mechanical ventilation and is a part of the spectrum of ventilator-associated respiratory infections. In the Intensive Care Units (ICUs), VAT is a relatively common problem but in comparison to ventilator-associated pneumonia (VAP), much less data are available on VAT and its management.

Materials And Methods: Patients ventilated for more than 48 hours were screened daily for the development of VAT.

Dengue, transmitted by the mosquito affects millions of people worldwide every year. Dengue induced hemophagocytic lymphohistiocytosis (HLH) is a serious condition and may prove fatal if not detected early and treated appropriately. Diagnosis of HLH is challenging and usually missed as clinical and laboratory findings are nonspecific.

Cladophialophora bantiana is a dematiceous fungus with neurotrophic propensity for which therapy is not standardized and mortality is high. We report here a 49 year old non-diabetic renal transplant patient on triple immunosuppressant therapy who presented with a history of falls, weakness and headaches. A computed tomography scan of the brain revealed a 30 mm diameter abscess in the brain which was removed surgically and diagnosed on culture as C.
