Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Silica Aerogel Microparticles from Rice Husk Ash for Drug Delivery

The present work describes an improved process for preparation of silica aerogel microparticles (SAMs) for drug delivery from rice husk ash (RHA), an inexpensive source rich in biocompatible silica. The wet gel microparticles were produced by a solgel method using water-in-oil emulsion, where a mineral oil replaced vegetable oil for easy separation using less energy. Taguchi design of experiments was used to optimize the parameters controlling the solgel method. The wet gel particles were dried with supercritical carbon dioxide (scCO(2)) to obtain SAMs. They were characterized by their properties such as BET surface area, pore volume, pore diameter and morphology. The efficacy of the improved process was validated by loading a water insoluble drug, ibuprofen, and a food preservative, eugenol, in SAMs from scCO(2) medium. The release kinetics of ibuprofen and eugenol from the loaded SAMs was studied. High loading and fast release kinetics confirmed that SAMs produced by the process are suitable for drug delivery

Copyright: Copyright 2021 Elsevier B.V., All rights reserved.Hybrid heterojunction solar cells based on silicon and single-walled carbon nanotube (SWCNT) thin films have a simple structure and their manufacture employ simple low-temperature processes. Moreover, their progress has been rapid during the last decade, wherein the efficiency of heterojunction solar cells combining hydrogenated amorphous silicon (a-Si:H) and SWCNTs thin film has increased from 0.03% to 8.80%. Here, we present a comprehensive overview of the state-of-the-art on SWCNTs/a-Si:H heterojunction solar cells. In addition to a comprehensive technology review, important special features such as adhesion of SWCNT film to a-Si:H, the interface between SWCNT and a-Si:H, and their influence on the performance of the heterojunctions are included. Future paths for improving the performance of such solar cells are also suggested. Finally, key challenges and trends for further research and development of SWCNTs/amorphous silicon heterojunction solar cells are discussed.

Effects of Partial Edge Loading and Fibre Configuration on Vibration and Buckling Characteristics of Stiffened Composite Plates

Abstract In this work, the influence of uniaxial and biaxial partial edge loads on buckling and vibration characteristics of stiffened laminated plates is examined by using finite element method. As the initial pre-buckling stress distributions within an element are highly non-uniform in nature for a given loading and edge conditions, the critical loads are evaluated by dynamic approach. Towards this, a nine-node heterosis plate element and a compatible three-node beam element are developed by employing the effect of shear deformation for both the plate and the stiffeners respectively. In the structural modeling, the plate and the stiffener elements are treated separately, and then the displacement compatibility is maintained between them by using a transformation matrix. Effect of different parameters such as loaded edge width, position of loads, boundary conditions, ply-orientations and stiffener factors are considered in this study. Buckling results show that the uniaxial loaded stiffened plate with around (+30º/-30º)2 layup can withstand higher load irrespective of boundary conditions and loading patterns, whereas the maximum load resisting layup for the bi-axially loaded stiffened plate is purely dependent on edge conditions and loading patterns

Not AvailableAn investigation was carried out to study the effect of feeding Moringa leaf meal-based diets on the biometry and body condition score in Deccani growing lambs. Eighteen growing either sex of lambs with uniform body weights (14.22 ± 1.5 kg) and aged between 4 and 8 months were selected for the study and randomly allotted to three treatment groups with six lambs in each group (6 x 3). Three experimental diets were prepared using 100 per cent groundnut cake (T1), 75% groundnut cake+ 25% Moringa oliefera leaf meal (T2) and 50% groundnut cake+ 50 % Moringa oliefera leaf meal (T3) as protein source in the concentrate mixture and all lambs fed with ad libitum green fodder. The investigation was conducted for 90 days. The fortnightly biometric measurement findings indicated that the mean fortnight body length, face length and hip width of growing Deccani lambs increased linearly throughout the experimental period and body length had a significant difference (P<0.05) among the treatments while the height at wither, chest girth, face length and tail length showed non-significance difference between the groups. The final body condition score was significant (P<0.01) among the three treatment groups. Significantly (P<0.05) higher BCS was observed in T2 group lambs than T1 and T3 group lambs from 3rd to 6th fortnight. Inclusion of Moringa oliefera leaf meal at 25% in the concentrate mixture improved the biometry and body condition score in lambs reared in intensive farming systemNot Availabl

Not AvailableBackground: Moringa (Moringa oleifera) is a highly valued plant grown in tropical and subtropical countries. Moringa has a high amount of crude protein, a well-balanced amino acid profile, vitamins and minerals and fewer quantities of antinutritive factors. Methods: Eighteen growing Deccani lambs of uniform body weight (14.22±1.5 kg) and age were randomly allotted to three treatment groups viz., 100 per cent groundnut cake (T1), 75% groundnut cake+ 25% Moringa oliefera leaf meal (T2) and 50% groundnut cake+ 50% M. oliefera leaf meal (T3) as a protein source in the concentrate mixture. The experiment was conducted for 90 days. Result: No significant difference was found in the fortnightly body weights of the lambs from 1st to 6th fortnights among three dietary groups. Total weight gain and Average Daily gain (ADG) were significant (P less than 0.01) among the treatment groups whereas DMI (kg/day), per 100 kg and FCR was non-significant. The digestibility coefficients (%) of all nutrients were non-significant (P greater than 0.05) except the NFE. Pre-slaughter weight, empty body weight, hot carcass weights and dressing percent on pre-slaughter weight and empty body weight were comparable among the three groups. Results of the present study indicated that inclusion of 25% Moringa oleifera leaf meal in concentrate mixture proved to be superior and improved the growth performance, digestibility of nutrients and carcass traits without any adverse effects on experimental lambs.Not Availabl

The Vibrio Pathogenicity Island of Epidemic Vibrio cholerae Forms Precise Extrachromosomal Circular Excision Products

The Vibrio pathogenicity island (VPI) in epidemic Vibrio cholerae is an essential virulence gene cluster. Like many pathogenicity islands, the VPI has at its termini a phage-like integrase gene (int), a transposase-like gene (vpiT), and phage-like attachment (att) sites, and is inserted at a tRNA-like locus (ssrA). We report that the VPI precisely excises from the chromosome and that its left and right ends join to form an extrachromosomal circular excision product (pVPI). Two-stage nested PCR analysis and DNA sequencing confirmed the int-att-vpiT junction and that the core attP of pVPI is identical to the chromosomal VPI attR site. Excision was independent of toxR and toxT. Excision was independent of recA, suggesting that it is mediated by site-specific recombination. Interestingly, while excision was detected in int and vpiT mutants, excision was abolished in a double (int vpiT) mutant and was restored by plasmids containing genes for either recombinase. Excision results in deletion of A361 in the ssrA locus, which flanks the right junction of the VPI. Since A361 encodes U70 in the critical G · U base pair in the acceptor stem of the ssrA RNA that is the determinant for aminoacylation with alanine, this deletion might have deleterious effects on ssrA function. Also, vpiT may have undergone interchromosomal translocation or may represent an independent integration event, as it was found downstream of hutA in some isolates. Our results provide new insight into the molecular biology of the VPI, and we propose that the process of excision and circularization is important in the emergence, pathogenesis, and persistence of epidemic V. cholerae
