ABSTRACT
The aim of the study was to evaluate the efficacy and safety of an RNA double-stranded sodium salt drug, a lyophilisate for a solution preparation for an intramuscular and subcutaneous administration, as a means of post-exposure COVID-19 prophylaxis in comparison with placebo.Material and methods. A double-blind, placebo-controlled, multicenter, randomized phase III clinical trial was conducted to evaluate the efficacy and safety of a double-stranded sodium salt RNA drug (RADAM IN (R) VIRO), a lyophilisate for preparing a solution for intramuscular and subcutaneous administration as a means of post-exposure prophylaxis of COVID-19. The study was conducted in 10 research centers in the Russian Federation from May 31, 2022 to January 17, 2023. The study included men and women aged =18 years who cohabitate with a person with a documented COVID-19 diagnosis and do not have symptoms characteristic of COVID-19. At the randomization stage, the subjects were assigned to one of two groups: group 1 (n=400) received a study drug RADAM IN (R) VIRO 5 mg (1 vial) intramuscularly once a day;group 2 (n=400) received placebo 1 vial intramuscularly once a day. The total duration of the study for each subject was no more than 30 days.Results. By day 10-11, in the double-stranded sodium salt RNA drug group, the proportion of the subjects with confirmed COVID-19 and at least 1 symptom characteristic of COVID-19 was 5.76% (23/399), and in the placebo group - 11.03% (44/399). The difference in proportions between the study drug and placebo groups was 0.0526 (5.26%), the 95% confidence interval (CI) for the difference in proportions between the groups was [0.0123;0.0937]). More than 94% of single-dose subjects did not become infected with COVID-19 with any symptoms during the 11 days of the follow-up. As a result of a comparative analysis, it was shown that the infection frequency in the study drug group was statistically significantly (almost twice) less than in the comparison group, which indicates a high efficiency and expediency of using the double-stranded sodium salt RNA drug as a means of the post-exposure COVID-19 prophylaxis.Conclusion. Thus, regardless of the vaccination availability, the effectiveness and feasibility of using the study double -stranded sodium salt RNA drug as a means of the post-exposure COVID-19 prophylaxis was demonstrated not only in medical institutions (outpatient clinics and hospitals), but also in caregivers and/or the persons in contact with COVID-19 patients. The situation was the same in the organizations and enterprises in case of evolution of a mass infection threat and the availability of appropriate medical personnels.
ABSTRACT
Online media are potentially useful teaching resources, especially for students studying from home during the coronavirus disease (COVID-19) pandemic. Previous research found that this method can improve understanding of the material other than the face-to-face method. This study evaluated whether online nutrition education could influence the sugar, salt, and fat diet of elementary school students. Semarang City served as the site of this experimental study. Participants in this study were given a weekly online nutrition education intervention for eight weeks. Based on the inclusion and exclusion criteria, 100 students were randomly selected and divided into two groups, so that 45 students remained until the end of the study in the control group, while the intervention group had 39 students. Data on general characteristics, self-reported anthropometry, sugar, salt, and fat eating patterns, and variables influencing social media use, were gathered. The data were analyzed through descriptive, bivariate, and multivariate analyses. In this study, students used YouTube more often (83.7%) than other social media platforms. The intervention caused a shift in the students' dietary patterns. The scores of fried food consumption in both groups and sugary food consumption in the control group varied before and after the interventions. There was no difference in the delta scores between the intervention and control groups;however, it was 4.1 times harder for female students than for male students to change their eating habits. Even though there was no significant difference between the two groups, online nutrition education could alter high-sugar and high-fat diets.
ABSTRACT
A viral transport medium (VTM) was developed following the Centers for Disease Control and Prevention, USA (US-CDC) standard operating procedure (SOP) DSR-052-05 with necessary improvisation and was used for storing coronavirus disease 2019 (COVID-19) swab specimens. Considering Bangladesh's supply chain and storage conditions, improvisation was essential for extending sample storage time while retaining efficiency. In-house VTM was produced using Hank's balanced salt solution (HBSS) supplemented with 1% bovine serum albumin V (BSA), 0.5 µg /mL of gentamicin sulfate, and 100 µg/mL of fluconazole. The produced VTM composition, quality, sterility, specificity, and efficiency were verified in-house and through an independent contract research organization (CRO). An accelerated stability study projected that under the recommended temperature (4 °C), it would remain stable for four months and preserve samples for over a month. The real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) test detected the targeted N gene and ORF1ab gene from the VTM stored samples. Our VTM is equally as effective as the Sansure Biotech VTM in keeping SARS-CoV-2 RNA specimens detectable in rRT-PCR (100% sensitivity and specificity in random and blinded samples). In conclusion, the BRiCM VTM will make the battle against pandemics easier by effectively collecting and storing nasopharyngeal and oropharyngeal swabs for COVID-19 detection.
ABSTRACT
With the outbreak of COVID-19, disinfection protection has become a necessary measure to prevent infection. As a new type of disinfectant, potassium peroxymonosulfate compound salt (PMS) has the advantages of good bactericidal effect, non-toxicity, high safety and stability. However, the current PMS products with irregular particle shapes lead to poor flowability, high hygroscopicity, poor stability of reactive oxygen species (ROS) and serious caking problems. In this work, an agglomeration-dissolution mechanism was designed to prepare spherical PMS particles with large size (>300 mm) and high sphericity (up to 90%), effectively addressing the above problems. Shaping (dissolution and abrasion) is the key to improving sphericity, which is mainly controlled by the design of the heating mode, residence time and stirring rate. Compared with the irregular PMS particles, the large spherical particles present better flowability (angle of repose decreased by 35.80%, Carr's index decreased by 64.29%, Hausner's ratio decreased by 19.14%), lower hygroscopicity (decreased by 38.0%), lower caking ratio (decreased by 84.50%), and higher stability (the monthly loss of ROS was reduced by 61.68%). The agglomeration -dissolution mechanism demonstrates the crystallization, agglomeration, dissolution and abrasion pro-cess of inorganic salt crystals, providing an opportunity to prepare high-end inorganic crystal materials with high-quality morphologies.(c) 2022 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.

The included studies were those that analyzed the effect of viral load reduction by mouthwashes, primary studies, no reviews and in Spanish, English or Portuguese. Result(s): The search resulted in 1881 articles, at the end of the exclusion of duplicates and selection, 71 articles were included in this scoping review. The substances most commonly found were chlorhexidine (CHX), povidone-iodine (PVP-I), essential oils (EO), cetylpyridinium chloride (CPC), hydrogen peroxide (H2O2) and other substances (OTHERS). Conclusion(s): Of all the mouthwashes analyzed, the Essential oils, Cetylpyridinium Chloride and Povidone-iodine, showed antiviral potential against common viruses present in the oral cavity, with no significant side effects in short-term use, and are viable options for use as a pre-procedure in clinical routine against SARS-CoV-2 and other types of viruses. The other solutions need further studies to determine their effect and confirm their clinical use.Copyright © 2023
ABSTRACT
Millions of people will now suffer from long-term smell loss as a result of infection with the SARS-CoV-2 virus. Smell is an integral component of the flavor of foods, which is one of the primary drivers of ingestive behavior. When individuals lose their sense of smell, they find food to be less flavorful and less enjoyable, which negatively impacts their quality of life. To compensate, many individuals alter their diet by focusing on tastes, chemesthesis (e.g., chili pepper heat, menthol cooling), and the texture of foods to make it more palatable. Some diet alterations, such as increasing salt use, can result in a lower diet quality, and an increased risk for chronic disease. Sensory nutrition is an area of research that focuses on how the chemical senses (e.g. taste, smell, chemesthesis) and oral somatosensation) affect dietary choices and health. Sensory nutrition strategies designed for individuals with smell loss may help improve the flavor and liking of foods while improving diet quality, and are a necessary area of future research to help improve health and quality of life in the growing population with smell loss.Copyright © 2022 The Author(s)
ABSTRACT
The analysis of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) gene copy numbers in wastewater samples can provide quantitative information on Coronavirus Disease-19 (COVID-19) cases within a sewer catchment. However, many wastewater-based epidemiology (WBE) studies have neglected virus decay during the wastewater transportation process in sewers while back-calculating COVID-19 prevalence. Among various sewer condition parameters, wastewater temperature and dilution by fresh/saltwater infiltration may result in a significant change to the virus decay, in terms of both infectivity and Ribonucleic Acid (RNA). This paper reviewed the literature to identify and discuss the effects of temperature and water types (i.e., wastewater, freshwater, and seawater) on coronavirus decay based on the decay rate constants that were collected from published papers. To evaluate the importance of virus decay, a sensitivity analysis was then conducted with decay rates of SARS-CoV-2 RNA based on a WBE back-calculation equation. Finally, the decay rates of coronavirus in wastewater were also compared with those of other viruses to further understand the difference among virus species. The decay of SARS-CoV-2 RNA was found to be less impacted by temperature variation than viable coronaviruses. Nevertheless, WBE back-calculation was still sensitive to the RNA decay rates increased by warm wastewater (i.e., over 26 °C), which could lead to a two-times higher relative variance in estimated COVID-19 prevalence, considering the wastewater temperature variation between 4 and 37 °C in a sewer catchment with a 12-h hydraulic retention time. Comparatively, the sensitivity of the WBE estimation to the enveloped SARS-CoV-2 was greater than nonenveloped enteric viruses, which were less easily degradable in wastewater. In addition, wastewater dilution by stormwater inflow and accompanied cold weather might alleviate the decay of coronavirus infectivity, thus increasing the potential risk of COVID-19 transmission through wastewater. Overall, this paper aims to better understand the impact of in-sewer processes on coronavirus decay and its potential implications for WBE. The outcome could quantitatively inform WBE and improve awareness of the increased risk of COVID-19 infection via wastewater during heavy rainfall events. Given the identified scarcity of data available for coronavirus decay in salt water or with chemical additions, future research on the fate of SARS-CoV-2 subjected to chemical dosing for sewer or wastewater treatment plant operations is recommended. © 2023 by the authors.

ABSTRACT
Hospital acquired-Staphylococcus aureus (HA-Staphylococcus aureus), particularly methicillin-resistant Staphylococcus aureus (MRSA), are an important source of nosocomial infections with high morbidity and mortality rates. Few reports showed that infections due to HA-Staphylococcus aureus in Saudi Arabia is increasing, particularly infections attributed to HA-MRSA. The study aimed to explore the prevalence and clinical characteristics of HA-Staphylococcus aureus for the first time in Medina, Saudi Arabia. A total of 1262 clinical samples of hospitalized patients were examined for the presence of Staphylococcus aureus through selective culturing on mannitol salt agar. Vitek Compact System and conventional methods were followed to confirm the isolates. Vitek Compact System tested the antimicrobial susceptibility of isolates whereas the standard PCR was employed to detect the genes encoding antimicrobial resistance (mecA and vanA) and virulence factors (tst, et, and LukS-PV). The overall HA-Staphylococcus aureus prevalence was low (6.58%, n = 1262) of which 84.34% (n = 83) were MRSA. Approximately, 57 samples of the 70 MRSA (81.5%) exhibited a multidrug-resistance (MDR) pattern. All the 83 HA-Staphylococcus aureus isolates were negative for the genes encoding toxic shock syndrome toxin, exfoliative toxin, and Panton-Valentine leukocidin. The study was conducted during the Covid-19 pandemic under partial lockdown, restricted hospitalization, and increased disinfection and infection control measures. Therefore, the low prevalence of HA-Staphylococcus aureus should be carefully interpreted and further multicenter investigations could reveal its true incidence in the city. The high prevalence of MDR HA-MRSA is alarming as it highlights inappropriate antibiotic prescriptions to counter staphylococcal infections. HA-Staphylococcus aureus investigated in this study might lack certain virulence factors. However, their MDR traits and invasive nature could worsen the situation if not properly handled.

ABSTRACT
In recent years, more and more data has become available about the benefits of green in and around cities. Vegetation helps people to recover faster from illness;this reduces costs of healthcare and improves the patients ' quality of life. In highly urbanized locations, the design of green elements requires special attention. Our paper presents a multidisciplinary study of areas located near the old salt mines and their use by entering in the spa and leisure circuit. Specific components were monitored, like the salted waters quality in lakes and/or springs and the identification of different plant species adapted to high salinity of the soil and able to enrich a green zone. In recent years, the continuous degradation of environmental quality due to factors such as air pollution, noise, chemical compounds, the pandemic state due to COVID-19 and disappearance of natural areas, in combination with lifestyle changes led to the emergence of a growing number of diseases such as different forms of diabetes, cardiovascular and nervous system disorders and cancer.
ABSTRACT
Herein, we describe a one-step method for synthesizing cationic acrylate-based core-shell latex (CACS latex), which is used to prepare architectural coatings with excellent antimicrobial properties. Firstly, a polymerizable water-soluble quaternary ammonium salt (QAS-BN) was synthesized using 2-(Dimethylamine) ethyl methacrylate (DMAEMA) and benzyl bromide by the Hoffman alkylation reaction. Then QAS-BN, butyl acrylate (BA), methyl methacrylate (MMA), and vinyltriethoxysilane (VTES) as reactants and 2,2'-azobis(2-methylpropionamidine) dihydrochloride (AIBA) as a water-soluble initiator were used to synthesize the CACS latex. The effect of the QAS-BN dosage on the properties of the emulsion and latex film was systematically investigated. The TGA results showed that using QAS-BN reduced the latex film's initial degradation temperature but improved its thermal stability. In the transmission electron microscopy (TEM) photographs, the self-stratification of latex particles with a high dosage of QAS-BN was observed, forming a core-shell structure of latex particles. The DSC, TGA, XPS, SEM, and performance tests confirmed the core-shell structure of the latex particles. The relationship between the formation of the core-shell structure and the content of QAS-BN was proved. The formation of the core-shell structure was due to the preferential reaction of water-soluble monomers in the aqueous phase, which led to the aggregation of hydrophilic groups, resulting in the formation of soft-core and hard-shell latex particles. However, the water resistance of the films formed by CACS latex was greatly reduced. We introduced a p-chloromethyl styrene and n-hexane diamine (p-CMS/EDA) crosslinking system, effectively improving the water resistance in this study. Finally, the antimicrobial coating was prepared with a CACS emulsion of 7 wt.% QAS-BN and 2 wt.% p-CMS/EDA. The antibacterial activity rates of this antimicrobial coating against E. coli and S. aureus were 99.99%. The antiviral activity rates against H3N2, HCoV-229E, and EV71 were 99.4%, 99.2%, and 97.9%, respectively. This study provides a novel idea for the morphological design of latex particles. A new architectural coating with broad-spectrum antimicrobial properties was obtained, which has important public health and safety applications.

BACKGROUND: Even modest reductions in blood pressure (BP) can have an important impact on population-level morbidity and mortality from cardiovascular disease. There are 2 promising approaches: the SaltSwitch smartphone app, which enables users to scan the bar code of a packaged food using their smartphone camera and receive an immediate, interpretive traffic light nutrition label on-screen alongside a list of healthier, lower-salt options in the same food category; and reduced-sodium salts (RSSs), which are an alternative to regular table salt that are lower in sodium and higher in potassium but have a similar mouthfeel, taste, and flavor. OBJECTIVE: Our aim was to determine whether a 12-week intervention with a sodium-reduction package comprising the SaltSwitch smartphone app and an RSS could reduce urinary sodium excretion in adults with high BP. METHODS: A 2-arm parallel randomized controlled trial was conducted in New Zealand (target n=326). Following a 2-week baseline period, adults who owned a smartphone and had high BP (≥140/85 mm Hg) were randomized in a 1:1 ratio to the intervention (SaltSwitch smartphone app + RSS) or control (generic heart-healthy eating information from The Heart Foundation of New Zealand). The primary outcome was 24-hour urinary sodium excretion at 12 weeks estimated via spot urine. Secondary outcomes were urinary potassium excretion, BP, sodium content of food purchases, and intervention use and acceptability. Intervention effects were assessed blinded using intention-to-treat analyses with generalized linear regression adjusting for baseline outcome measures, age, and ethnicity. RESULTS: A total of 168 adults were randomized (n=84, 50% per group) between June 2019 and February 2020. Challenges associated with the COVID-19 pandemic and smartphone technology detrimentally affected recruitment. The adjusted mean difference between groups was 547 (95% CI -331 to 1424) mg for estimated 24-hour urinary sodium excretion, 132 (95% CI -1083 to 1347) mg for urinary potassium excretion, -0.66 (95% CI -3.48 to 2.16) mm Hg for systolic BP, and 73 (95% CI -21 to 168) mg per 100 g for the sodium content of food purchases. Most intervention participants reported using the SaltSwitch app (48/64, 75%) and RSS (60/64, 94%). SaltSwitch was used on 6 shopping occasions, and approximately 1/2 tsp per week of RSS was consumed per household during the intervention. CONCLUSIONS: In this randomized controlled trial of a salt-reduction package, we found no evidence that dietary sodium intake was reduced in adults with high BP. These negative findings may be owing to lower-than-anticipated engagement with the trial intervention package. However, implementation and COVID-19-related challenges meant that the trial was underpowered, and it is possible that a real effect may have been missed.

BACKGROUND: Evidence has demonstrated that excess sodium intake is associated with development of several non-communicable diseases. The main source of sodium is salt. Therefore, reducing salt intake in foods is an important global public health effort to achieve sodium reduction and improve health. This study aimed to model salt intake reduction with 'umami' substances among Japanese adults. The umami substances considered in this study include glutamate or monosodium glutamates (MSG), calcium diglutamate (CDG), inosinate, and guanylate. METHODS: A total of 21,805 participants aged 57.8 years on average from the National Health and Nutrition Survey was used in the analysis. First, we employed a multivariable linear regression approach with overall salt intake (g/day) as a dependent variable, adjusting for food items and other covariates to estimate the contribution of salt intake from each food item that was selected through an extensive literature review. Assuming the participants already consume low-sodium products, we considered three scenarios in which salt intake could be reduced with the additional umami substances up to 30%, 60% and 100%. We estimated the total amount of population-level salt reduction for each scenario by age and gender. Under the 100% scenario, the Japan's achievement rates against the national and global salt intake reduction goals were also calculated. RESULTS: Without compromising the taste, the 100% or universal incorporation of umami substances into food items reduced the salt intake of Japanese adults by 12.8-22.3% at the population-level average, which is equivalent to 1.27-2.22 g of salt reduction. The universal incorporation of umami substances into food items changed daily mean salt intake of the total population from 9.95 g to 7.73 g: 10.83 g to 8.40 g for men and 9.21 g to 7.17 g for women, respectively. This study suggested that approximately 60% of Japanese adults could achieve the national dietary goal of 8 g/day, while only 7.6% would meet the global recommendation of 5.0 g/day. CONCLUSIONS: Our study provides essential information on the potential salt reduction with umami substances. The universal incorporation of umami substances into food items would enable the Japanese to achieve the national dietary goal. However, the reduced salt intake level still falls short of the global dietary recommendation.

Agriculture sustains the livelihoods of over 2.5 billion people worldwide. The growing nature of disasters, the systemic nature of risk, a more recent pandemic along with abiotic stress factors are endangering our entire food system. In these stressful environment, it is widely reprimanded that strategies should be encompassed to attain increased crop yield and economic returns which would alleviate food and nutritional scarcity in developing countries. To study the physiological responses to salt stress, Vigna radiata seedlings subjected to varying levels of salt stress (0, 25, 50, 100 and 200 mM NaCl) were evaluated by tracking changes in Chl a fluorescence, pigment content, free proline and carotenoids content by HPLC. The ability of plants to adapt to salt stress is related with the plasticity and resilience of photosynthesis. As salt concentration increased, chlorophyll fluorescence indices decreased and a reduction in the PSII linear electron transport rate was observed. Chlorophyll fluorescence parameters can be used for in vitro non-invasive monitoring of plants responses to salt stress. Overall, Vigna responded to salt stress by the changes in avoidance mechanism and protective systems. Chl fluorescence indices, enzymatic contents of POD, CAT and free proline were sensitive to salt stress. The study is significant to evaluate the tolerance mechanisms of plants to salt stress and may develop insights for breeding new salt-tolerant varieties.
ABSTRACT
Objective: Since nutrition could extend lifespan even in stroke-prone rats developing stroke genetically, our WHO-Collaborating Center for Primary Prevention of Cardio-vascular Diseases (CVD) started world-wide hearth examination to investigate nutrition good for healthy longevity by collecting 24-hour urine (24U) samples. Design: Urinary biomarkers of nutritions, sodium for salt, potassium (K) for vegetables and fruits, isoflavones(Is) for soy, taurine(Ta) for fish and magnesium (Mg) for beans and nuts were analyzed in 24U among 4211 participants (49.7% females(F)), aged 48-56 years in 50 populations from 22 countries according to WHO-CARDIAC(Cardiovascular Diseases and Alimentary Compression) Study Protocol, and studied comparatively in 6 Japanese(J), 6 Mediterranean(M) populations from Greece, Italy(2), Spain(2), Portugal and 6 Euro-Western(EW) populations from Sweden, Ireland, Scotland, Canada, Australia, New Zealand. Results with Discussion: The quintile analyses of Ta and Mg/creatine ratio in the world were inversely associated with CVD risks. The Odds ratios of obesity, hypercholesterolemia and hypertension in the lowest quintile of both Ta and Mg were 6.3, 4.6 and 1.8, respectively. J and M populations had significantly higher Ta and Mg therefore, lower CVD risks than EW, but J and M took more salt increasing the risk of stroke (Table 1). Despite the high salt intake, M had the merit of significantly high K intake to attenuate the adverse salt effect. J had a merit to take Is from soy containing Mg. Since Is intake was inversely associated with lower BMI in the world populations, high Japanese Mg intake was related to high Is intake which was inversely associated with obesity in Japan. In fact, the Japanese populations who took significantly higher T and Mg had lower BMI as well as higher HDL and folic acid in the blood, expected to prevent atherosclerosis and dementia. In contrast to M and EW, particularly severe obesity over BMI 30 was obviously less in J, ranking 182nd among 190 populations (WHO). The mortality rates of COVID-19 were significantly positively related to the ratio of severe obesity among 20 major countries in the world and this mortality was obviously lower in J, suggestive of the potential of J diet for post-pandemic longevity. Conclusion: 24U biomarker analyses indicated low-salted J and M diets are recommendable for CVD prevention. J diet is so far better than M diet because of lower CVD risks such as obesity and lipidemia, which were proven by urinary biomarkers to be related with traditional fish and soy intakes.
ABSTRACT
Purpose: As the average salt intake of Japanese people is as high as 10 gram per day, it is necessary to reduce the salt intake for the prevention and treatment of cardiovascular diseases. We held a less salt recipe contest to promote delicious less salt recipes among society and examined the potentiality of 'deliciously less salt meals'. Method: National Cerebral and Cardiovascular Center (NCVC) held the 'The 5th S-1 Grand Prix', a contest to develop delicious and less salt bento recipes on a nationwide scale. The contest named after its goal of reducing the salt intake by 1 gram in each meal. Under the theme of a delicious and attractive less salt bento meeting to the nutritional value standards (such as less than 2 gram of salt equivalent per meal), NCVC called for the bento recipe ideas from the 10th of May to 26th of July 2021. All the applied recipes are evaluated and tasted by NCVC contest board members, then the best one was decided for a 'Grand-Prix' award. Contest was held on-line due to the COVID-19, the video presentation made by the applicants were evaluated for the final selection. Result: A total of 67 teams (25 teams in the general category, 15 teams in the student category, 27 teams in the disaster nutrition category) were applied to this contest. We encouraged governments, hospitals, dietitian training schools, and convention-related companies and organizations nationwide to apply the contest. Compared to the 4th tournament, the number of applicants were increased by 16 teams. More than half of the applicants were from 'educational institutions such as universities'. Although the 5th tournament was held online, we were able to hold a recipe contest in a new format, such as using applicants' video presentation for the final selection. Discussion: In the disaster nutrition category, many recipes for the delicious, preserved foods and cooking methods under the disaster were gathered, so that these less salt recipes can be widely adopted in the disaster foods. Through this attempt, we created an opportunity to make a delicious less salt meals, and motivated participants to cook 'deliciously less salt meals'. In the future, more people will participate in this contest in order to get them to participate, we will consider the conditions of the recipe and the recruitment method.
ABSTRACT
The market for biostimulants is rapidly growing and many companies are expanding their portfolio with the introduction of these products, which are increasingly used to improve the management of crop systems and increase their sustainability. In fact, biostimulants, if properly used, can increase crop yields and quality, reducing fertilizer inputs and increasing plant tolerance against abiotic stresses.
ABSTRACT
Background. Complex fluid balance problems are well established post-neurosurgery and traumatic brain injury (TBI). The triple-phase response requires fluid management strategies reactive to urine output as patients shift between DI and SIADH. Prevalence of CSW is controversial;but ensuring sodium homeostasis is central to safe fluid management. To improve clinical care for these complex patients an audit of existing institutional guidelines was undertaken. New guidelines were developed with structured educational packages for specialist teams involved, and subsequent assessment of their impact. Method(s): Two periods were audited using set standards (table-1), before and after the quality improvements. All data was collected from the CQUIN neurosurgical database and electronic medical records;included were all paediatric patients having neurosurgical operations for posterior fossa (PFT) and supratentorial tumours (STT), plus TBI. A literature review of evidence-based practice, initial audit data and stakeholder feedback was used to develop new clinical guidelines and nursing standard operating procedures. Principles were of strict monitoring and adaptive fluid management strategies, implemented for all with active step down. Structured educational packages were designed for specialty medical and nursing teams involved to improve knowledge, consistency of approach and team working. Result(s): Audit-1 January2017-June2018, n=80;Audit-2 January2020-June2021, n=30 (reduced neurosurgical operation numbers due to COVID-19 pandemic). All patients were managed within a high dependency setting;26-33% initially in paediatric intensive care. Step-down was to a neurosurgical/neurorehabilitation ward. Results comparison (table-1) demonstrated clinical, fluid balance and biochemical monitoring improvement. The number of clear fluid management plans documented post-operatively increased, leading to early recognition and management of evolving fluid-balance abnormalities. However, the recommended adaptive fluid management strategy was not always used. The endocrine team were involved earlier and in all complex cases. Significant Na fluctuations (>12mmol in 24 hours) remained similar (5vs6patients). These represented complex pituitary-hypothalamic pathology, plus one TBI. Feedback from patients and professional teams was of increased awareness, improved consistency of approach and communication. Conclusion(s): * Clinical guidelines revised using audited data, evidence-based literature review and stakeholder consultation have been adopted with effective change. * Patient safety improved through effective post-neurosurgical fluid management and multi-professional team working. * Regular feedback and continued education will identify areas for further improvement.
ABSTRACT
Chemical irritants, like piperine, have the potential to increase human perception of tastes and odours, including saltiness. This cross-modal interaction could help the food industry develop new salt-reduced food products that maintain their salty taste. The objective of this study was: firstly, to determine the detection threshold of piperine (n = 72), secondly to evaluate piperine's influence on saltiness perception in model solutions (n = 78), and lastly to identify piperine's effect on sensory perception of low sodium soup using temporal check-all-that-apply (TCATA; n = 75). The group mean of the individual threshold was 0.55 ± 0.15 ppm. Piperine increased the saltiness perception of the model solutions, but it also increased the bitterness and decreased the sweetness of the solutions. The piperine significantly increased the saltiness intensity of the soups (evaluated using a generalized labelled magnitude), but during the TCATA task, the salty attribute was selected less for the soup with piperine than the control (based on the average proportion of selection). The TCATA indicated that the peppery attribute dominated the participants' perception of the soup with piperine. More studies are needed to assess piperine's cross-modal interactions.
ABSTRACT
With the outbreak of COVID-19, disinfection protection has become a necessary measure to prevent infection. As a new type of disinfectant, potassium peroxymonosulfate compound salt (PMS) has the advantages of good bactericidal effect, non-toxicity, high safety and stability. However, the current PMS products with irregular particle shapes lead to poor flowability, high hygroscopicity, poor stability of reactive oxygen species (ROS) and serious caking problems. In this work, an agglomeration-dissolution mechanism was designed to prepare spherical PMS particles with large size (>300 μm) and high sphericity (up to 90%), effectively addressing the above problems. Shaping (dissolution and abrasion) is the key to improving sphericity, which is mainly controlled by the design of the heating mode, residence time and stirring rate. Compared with the irregular PMS particles, the large spherical particles present better flowability (angle of repose decreased by 35.80%, Carr's index decreased by 64.29%, Hausner's ratio decreased by 19.14%), lower hygroscopicity (decreased by 38.0%), lower caking ratio (decreased by 84.50%), and higher stability (the monthly loss of ROS was reduced by 61.68%). The agglomeration-dissolution mechanism demonstrates the crystallization, agglomeration, dissolution and abrasion process of inorganic salt crystals, providing an opportunity to prepare high-end inorganic crystal materials with high-quality morphologies. © 2022 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences
