Abstract

BACKGROUND: Staphylococcus aureus bacteraemia (SAB) is one of the commonest bloodstream infections globally and is associated with a high mortality rate. Most published data comes from temperate, high-income countries. We describe the clinical epidemiology, microbiology, management and outcomes of patients with SAB treated in a tropical, middle-income setting at Fiji's largest hospital. METHODS: A prospective, observational study was performed of consecutive SAB cases admitted to Colonial War Memorial Hospital (CWMH) in Suva, between July 2020 and February 2021. Detailed demographic, clinical and microbiological data were collected, including the key outcome of in-patient mortality. To estimate the population incidence, all SAB cases diagnosed at the CWMH laboratory were included - even if not admitted to CWMH - with the population of Fiji's Central Division used as the denominator. FINDINGS: A total of 176 cases of SAB were detected over eight-months, which equated to an incidence of 68.8 cases per 100,000 population per year. Of these, 95 cases were admitted to CWMH within 48 h of index culture. Approximately 8.4% (8/95) of admitted cases were caused by methicillin-resistant Staphylococcus aureus (MRSA). All cause in-patient mortality was 25.3%, increasing to 55% among patients aged 60 or older. INTERPRETATION: This reported incidence of SAB in central Fiji is one of the highest in the world. SAB was associated with significant mortality, especially in those over 60 years of age, despite a relatively low frequency of methicillin resistance. FUNDING: Supported by the National Health and Medical Research Council (Australia) and the GRAM (Global Research on Antimicrobial Resistance) Project, Oxford University (United Kingdom).

Abstract

Development of polymeric magnetic adsorbents is a promising approach to obtain efficient treatment of contaminated water. However, the synthesis of magnetic composites involving multiple components frequently involves tedious preparation steps. In the present study, a magnetic chitosan-palygorskite (MCP) nanocomposite was prepared through a straight-forward one pot synthesis approach to evaluate its lead (Pb2+) removal capacity from aqueous solution. The nano-architectural and physicochemical properties of the newly-developed MCP composite were described via micro- and nano-morphological analyses, and crystallinity, surface porosity and magnetic susceptibility measurements. The MCP nanocomposite was capable to remove up to 58.5 mg Pb2+ g−1 of MCP from water with a good agreement of experimental data to the Langmuir isotherm model (R2 = 0.98). The Pb2+ adsorption process on MCP was a multistep diffusion-controlled phenomenon evidenced by the well-fitting of kinetic adsorption data to the intra-particle diffusion model (R2 = 0.96). Thermodynamic analysis suggested that the adsorption process at low Pb2+ concentration was controlled by chemisorption, whereas that at high Pb2+ concentration was dominated by physical adsorption. X-ray photoelectron and Fourier transform infrared spectroscopy results suggested that the Pb adsorption on MCP was governed by surface complexation and chemical reduction mechanisms. During regeneration, the MCP retained 82% Pb2+ adsorption capacity following four adsorption–desorption cycles with ease to recover the adsorbent using its strong magnetic property. These findings highlight the enhanced structural properties of the easily-prepared nanocomposite which holds outstanding potential to be used as an inexpensive and green adsorbent for remediating Pb2+ contaminated water.

Abstract

OBJECTIVES: There are scant primary clinical data on antimicrobial resistance (AMR) burden from low- and middle-income countries (LMICs). We adapted recent World Health Organization methodology to measure the effect of third-generation cephalosporin resistance (3GC-R) on mortality and excess length of hospital stay in Fiji. METHODS: We conducted a prospective cohort study of inpatients with Enterobacterales bloodstream infections (BSIs) at Colonial War Memorial Hospital, Suva. We used cause-specific Cox proportional hazards models to estimate the effect of 3GC-R on the daily risk (hazard) of in-hospital mortality and being discharged alive (competing risks), and we used multistate modelling to estimate the excess length of hospital stay. RESULTS: From July 2020 to February 2021 we identified 162 consecutive Enterobacterales BSIs; 3GC-R was present in 66 (40.7%). Crude mortality for patients with 3GC-susceptible and 3GC-R BSIs was 16.7% (16/96) and 30.3% (20/66), respectively. 3GC-R was not associated with the in-hospital mortality hazard rate (adjusted hazard ratio [aHR] 1.13, 95% confidence interval [CI] 0.51-2.53) or being discharged alive (aHR 0.99, 95% CI 0.65-1.50), whereas Charlson comorbidity index score (aHR 1.62, 95% CI 1.36-1.93) and Pitt bacteraemia score (aHR 3.57, 95% CI 1.31-9.71) were both associated with an increased hazard rate of in-hospital mortality. 3GC-R was associated with an increased length of stay of 2.6 days (95% CI 2.5-2.8). 3GC-R was more common among hospital-associated infections, but genomics did not identify clonal transmission. CONCLUSION: Patients with Enterobacterales BSIs in Fiji had high mortality. There were high rates of 3GC-R, which was associated with increased hospital length of stay but not with in-hospital mortality.

104. Capability of Organically Modified Montmorillonite Nanoclay as a Carrier for Imidacloprid Delivery

Author

Abstract

Organically modified clays have attracted increasing research attention for their various commercial and industrial applications, such as being carriers for pesticide delivery. Besides, the suitability and performance of commercially available organoclays could further promote their applicability. Hence, this study investigated the potential application of a commercially available alkylamine-modified montmorillonite (MMT) nanoclay as a carrier for a widely used insecticide, imidacloprid. X-ray diffraction and thermogravimetric analysis were employed to illustrate the arrangement, orientation, and conformation of surface-modifying agents (SMAs) on MMT nanoclay. It was observed that the clay was modified at an ∼1.0 cation exchange capacity, with the SMAs, especially octadecylamine, arranged in the MMT nanoclay as a bilayer to a pseudo-trilayer or a paraffin monolayer with a tilting angle of ∼25°, which indicated the nanoclay’s ability to adsorb a large amount of imidacloprid. The adsorption-desorption of imidacloprid to MMT nanoclay further confirmed this applicability. A high adsorption capacity (∼85 mg g-1) was observed, with a high reversibility in desorption, showing a hysteresis value of 0.75. Further, the adsorption kinetics and response of the nanoclay to imidacloprid revealed that, initially, a rapid sorption occurred due to a hydrophobic interaction. This was followed by a slower diffusion-controlled sorption due to hydrogen bonding to the internal binding sites. The releasing pattern of imidacloprid from the MMT nanoclay indicated its potential for the preparation of a slow-releasing pesticide formulation where the nanoclay will reduce the instantaneous release of the total amount of pesticide.

Abstract

The Pest Management Guide for Grapes in Washington presents various chemicals and their uses against pest problems in Washington vineyards. While the recommendations are based on eastern Washington conditions, the information may often be applied to similar pest problems found throughout the state. Specific and more detailed information on pests and diseases can be found in the Field Guide for Integrated Pest Management in Pacific Northwest Vineyards (PNW644). Recommendations are suggested guidelines. They are not intended to represent pest control programs. The use of other materials and varying rates and treatments for control of particular pests depends on individual circumstances.

129. Need for Policy to Reduce Sugar Consumption in Trinidad and Tobago?

Author

Naidu, R., Lutchmansingh, F., Sharma, A., and Teelucksingh, S.

Abstract

In a recent recommendation, the World Health Organization (WHO) advises that adults and children reduce free sugars to less than 10% of total daily energy intake. This guidance is based on research evidence for the relationship between sugar and chronic non-communicable diseases, specifically obesity, type 2 diabetes mellitus (T2D), cardiovascular disease as well as dental caries. Over-consumption of free sugars has been attributed largely to the availability and popularity of sugar-sweetened beverages (SSBs). Recent data have shown that the Caribbean region as a whole has high consumption of SSBs and Trinidad and Tobago has been singled out for having the highest daily intake in the world. The need to implement the new WHO guidance on sugar consumption is urgent, given the high and apparently increasing prevalence of obesity, T2D and dental caries particularly among the nation's children. This paper recommends that national policy for Trinidad and Tobago aimed at reducing sugar consumption should be developed and implemented and that such policy should be based on strategies that have been shown to be effective internationally and regionally but leave ample room for locally relevant, culturally sensitive and socially acceptable innovative models of intervention.

Abstract

Renewable energy–based solar photovoltaic (PV) generation is the best alternative for conventional energy sources because of its natural abundance and eco-friendly behavior. But high cost and low efficiency of PV panels are the biggest challenges for solar energy systems. To overcome the non-linear characteristics under all circumstances, maximum power point tracking (MPPT) helps us to obtain maximum efficiency from PV panel. MPPT algorithms are practical solutions to ensure the continuous operation of PV systems. This paper presents an organized and detailed review of MPPT techniques implemented for PV systems. There are conventional MPPT algorithms such as Perturb and observe (P&O) and Incremental conductance (INC) and soft computing techniques such as Fuzzy logic. Control (FLC), Cuckoo search (CS), Crow search algorithm (CSA) and whale optimization algorithm (WOA). So, this paper provides comparison of these MPPT techniques which will give us an idea to select the most prominent MPPT technique for further research. [ABSTRACT FROM AUTHOR]

This paper deals with the different control strategies used in the operation of Brushless motors, which generally refer to Permanent-Magnet Motors. These motors are becoming increasingly popular in industrial applications due to their high-efficiency, fast dynamic response and compact size. Until recently, programming and implementation costs of high-performance control algorithms for these motors have been prohibitive. However, great strides have been made by manufacturers such as Microchip, Freescale, IRetc to facilitate these algorithms in the architecture for their processors. This has brought down the development costs significantly and opened up whole new avenues for Brushless Motor. [ABSTRACT FROM AUTHOR]

Abstract

The development and implementation of Demand response (DR) projects are proposed using an efficient and adaptable household energy management system. These are classified as part of the smart grid's hybrid generation of Energy Storage Systems (ESS), Photovoltaic’s (PV), and Electric vehicles (EVs). Existing home energy management systems are unable to give their consumers a choice in order to ensure User comfort (UC) and do not offer a long-term solution for lowered carbon emissions. This study paper suggests using a Heuristic-based programmable energy management controller (HPEMC) to control energy consumption in residential buildings in order to minimise electricity costs, reduce carbon emissions, increase UC, and lower the peak-to-average ratio (PAR).In order to schedule smart appliances optimally and achieve our desired goals, we combined our proposed hybrid genetic particle swarm optimization (HGPO) algorithm with already-existing algorithms like the Genetic algorithm (GA), Binary particle swarm optimization algorithm (BPSO), Ant colony optimization algorithm (ACO), wind-driven optimization algorithm (WDO), and bacterial foraging algorithm (BFA). In the suggested scenario, consumers generate their own electricity from microgrids using solar panels. We also run MATLAB simulations to verify our suggested HGPO-HPEMC (HHPEMC), and the results show that our suggested HPEMC-based method is effective and productive. In comparison to the situation without scheduling, the Suggested algorithm lowered the cost of power generation and carbon emission. [ABSTRACT FROM AUTHOR]

Abstract

Before the end of the Epoch of Reionization, the Hydrogen in the Universe was predominantly neutral. This leads to a strong attenuation of Ly α lines of z ≳ 6 galaxies in the intergalactic medium. Nevertheless, Ly α has been detected up to very high redshifts (z ∼ 9) for several especially UV luminous galaxies. Here, we test to what extent the galaxy's local environment might impact the Ly α transmission of such sources. We present an analysis of dedicated Hubble Space Telescope (HST) imaging in the CANDELS/EGS field to search for fainter neighbours around three of the most UV luminous and most distant spectroscopically confirmed Ly α emitters: EGS-zs8-1, EGS-zs8-2, and EGSY-z8p7 at z spec = 7.73, 7.48, and 8.68, respectively. We combine the multiwavelength HST imaging with Spitzer data to reliably select z ∼ 7–9 galaxies around the central, UV-luminous sources. In all cases, we find a clear enhancement of neighbouring galaxies compared to the expected number in a blank field (by a factor ∼3–9×). Our analysis thus reveals ubiquitous overdensities around luminous Ly α emitting sources in the heart of the cosmic reionization epoch. We show that our results are in excellent agreement with expectations from the Dragons simulation, confirming the theoretical prediction that the first ionized bubbles preferentially formed in overdense regions. While three UV luminous galaxies already have spectroscopic redshifts, the majority of the remaining fainter, surrounding sources are yet to be confirmed via spectroscopy. JWST follow-up observations of the neighbouring galaxies identified here will thus be needed to confirm their physical association and to map out the ionized regions produced by these sources.
