Impact of monetary policy on firm’s risk-taking position and investment decision
Authors:   , Seneekosol Sakolwat
Published: June 2023

The recent economic crisis drives monetary policy to boost the economic situation. However, the side effect of monetary policy also dilutes firms' behavior in both risk-taking and investment decisions. This research investigates the effect of monetary policy from the international and local level using firms in 5 Southeast Asia stock markets. The risk and investment decision measurement technique in this paper using Expected Default Frequency and the investment dummy variables. The risk-taking model is based on panel fixed effect regression and the investment decision model is using a fixed-effect logistic model. This paper also extends the analysis to cover the different characteristics of firms (Non-bank and Bank). This paper also examines the extension on risk measurement in banking firms, Distance to capital, to observe the impact of capital adequacy policy in the banking business. The empirical results provide evidence of strong foreign monetary policy impact on all types of firms' behavior. Moreover, the banking firms also affected by local monetary policy especially their investment decision. Lastly, the risk measurement technique extension also proves the significance of capital adequacy policy in the banking business.
Industry size and deal initiation: evidence from merger and acquisition
Authors:   , Sriburapar Sirilak
Published: June 2023

Targets in small industries are more likely to initiate the deal than targets in large industries. Bidders are willing to pay more for target-initiated deals in small industries than in large industries. This research finds empirical evidence that industry size significantly impacts firms' decision to initiate the deal and bid premium. Targets in small industries are more plausibly to initiate the deal because the demand for target corporate assets is lower. Consequently, they receive lower premiums compared to targets in large industries.

Surprisingly the impact of target-initiated deals on premiums significantly depends on target industry size, the negative impact of target-initiated deals is larger in large industries. As a result, target-initiated deals in small industries receive higher premiums than target-initiated deals in large industries. The premium gap between bidder-initiated deals and target-initiated deals in small industries is narrower than in large industries.
Inflation level and equity mutual fund flows in aggregate
Authors:   , Dangsritham Boontarikar
Published: June 2023

This paper investigates the relationship of inflation level and aggregate equity mutual fund flows using Thai evidence. Sample period covered from 2006 to 2020. For the first objective, we investigate the relationship between realized inflation and net flow of money into equity mutual fund. Next, since investors are forward-looking, we extend the analysis to investigate the same relationship using forecasted inflation instead. Lastly, money supply is increasing since 2008 because of the first launch of QE. Also, inflation trend becomes lower since then. Our further exploration is whether there is a change in the relationship between inflation and aggregate equity mutual fund flow between pre-post 2008 period.

We find a strongly negative relationship between equity flows and realized inflation. When inflation is high, economic stability will be worsened and nominal interest rate is going up. As a result, there are outflows from equity. However, the same relationship is not founded using inflation expectation. Net equity mutual fund flows tend to move with the realized inflation rather than the forecasted. Furthermore, our findings show that there is a significant amount of fund flows into equity mutual fund since 2008 onwards, but we cannot detect any significant change in the relationship between inflation and aggregate equity mutual fund flows.
Inside the black box of financial analysts: what drives systematic forecast optimism?
Authors:   , Schmidt Christian
Published: June 2023

Despite past failures and a higher standard of regulation, excessive forecast optimism among financial analysts is still observable. It is mainly attributed to incentives provided by an underlying affiliated relationship. This paper investigates diverse market settings in the Thai stock market between 2005 and 2017 to break down the incentive structure in the analysts' forecasting process. First, banks and brokerage houses with an affiliated mutual fund family show an extreme forecast behavior, especially when the fund family is backed by high capital and has a large stake in the covered firm. Secondly, full-service banks are among the most optimistic analysts in the market, particularly when they act as a lead underwriter during an IPO. However, lead underwriters tend to revert optimism to average level one year after the equity issuance. Banks acting as share distributors during an IPO are not necessarily more optimistic than the analysts' general favorable level of optimism. The paper concludes that the pressure for banks and brokerage houses to generate trading, enhance deal flows, and favor the management of the covered company impacts the forecasting behavior of individual analysts.
Insider trading in family firms: evidence from Thailand
Authors:   , Pramukkiattiyos Paweenon
Published: June 2023

This study examines the profitability of corporate insider trading in Thailand's
stock market and whether the abnormal return depends on the company's
characteristics and insider characteristics. The result shows that there is a significant
abnormal return on corporate insider trading transactions. The difference in ownership
structure is also important, with the results supporting that insider trading by family
firms is more profitable than non-family firms. Moreover, the finding indicates that
the trading of CEOs has more valuable information about the company's prospects
than other insiders.
The lead-lag relationship of block trade single stock futures and the underlying stocks: evidence from Thailand
Authors:   , Wongvisavakorn Pimnapa
Published: June 2023

According to the efficient market hypothesis, there should not be any lead-lag relationship of the spot and futures price of the financial assets; however, many empirical studies have suggested otherwise.  This study uses the Vector Error Correction Model (VECM) and Granger causality test with the daily trading data of Thailand’s block trade single stock futures and its underlying securities of 42 companies from 2016 to 2020. It reveals both unidirectional and bidirectional relationships of spot and futures markets with a less dominant role of the futures market in the price discovery function.  None of the sample companies have both long-run and short-run causality from futures to spot market, and only 5% of the 42 companies show the leading role of the futures market in the long-run with bilateral interaction in the short-run.  The results contradict our hypothesis that block trade single stock futures lead the counterpart underlying stocks in the short-run and long-run despite the higher leverage, lower transaction cost, and no short sale restriction of the futures market.  The lead-lag relationship between block trade single stock futures and the underlying stocks in Thailand can provide insightful information for regulators and policymakers in promoting efficiency and improving the information asymmetry that would help create a better trading environment for investors.

Nichita Stănescu: “Chișinău is a white pearl, in so much pure green”
Authors: Grati Aliona
Published: June 2023

The article reconstructs the only visit of the Romanian poet Nichita Stănescu to Chişinău from a series of testimonies of local writers. Nichita Stănescu arrived in the capital of the Moldavian Soviet Socialist Republic in 1976, during a period of complicated Soviet-Romanian relations, which made difficult the communication between Romanian-language writers from the republics on the two banks of the Prut. The haloed poet in the Bucharest environment and recognized as an unmistakable symbol of Romanian lyricism enjoys special sympathy among the Romanian-language writers from Chișinău, so the news of his participation in the events of the Soviet Literature Week in Moldova festival provoked and attracted attention. Every gesture he made, from the barely sketched to the exaggerated expressions, became a veritable charming show that was fixed in the memory of the witnesses and generated miniature stories. The stories about Nichita Stănescu first circulated in oral form, as living folklore in the narrow circles of writers. When it became possible, a series of testimonies about the gestures of the beloved Romanian poet appeared in the press. Together, the evocations of the “gentle angel who announced the opening of the windows” created the portrait of a Nichita Stănescu of Chișinău residents. In turn, Nichita Stănescu left a particularly expressive and representative metaphor about the city of Chişinău, of which she said was “a white pearl, in so much pure green”.

Dinâmica hidrossedimentológica do rio Urucuia, Minas Gerais
Authors: Teixeira Clareana Morato , Viola Marcelo Ribeiro , Coelho Gilberto , Avanzi Junior Cesar , Junqueira Rubens
Published: June 2023

Os estudos acerca da descarga sólida dos corpos hídricos são importantes para a gestão de recursos hídricos, uma vez que os sedimentos interferem diretamente na qualidade da água e no assoreamento de reservatórios. Uma vez que a concentração de sedimentos em suspensão está relacionada com o comportamento espectral, produtos obtidos por sensoriamento remoto orbital podem corroborar para pesquisas sobre a dinâmica hidrossedimentológica em cursos d’água. O rio Urucuia é um importante afluente pela margem esquerda do rio São Francisco na mesoregião noroeste de Minas Gerais. Nesse contexto, objetivou-se no presente estudo analisar a dinâmica hidrossedimentológica da bacia hidrográfica do rio Urucuia a partir de dados coletados em campo, e analisar a aplicabilidade de imagens do sensor TM do satélite Landsat 5 para predição da concentração de sedimentos em suspensão. Os resultados mostraram que a precipitação média na bacia é de 1.305,4 mm, com deflúvio anual de 314,9 mm. A partir de dados monitorados de vazão e de sedimentos em suspensão do posto fluviométrico Arinos-Montante obteve-se uma curva de descarga de sedimentos com r² igual a 0,88. A produção específica de sedimentos em suspensão foi classificada como “moderada”, sendo de 95,1 Mg.km-2.ano-1.Verificou-se que as bandas 2, 3 e 4 do sensor TM do satélite Landsat 5 são as que apresentam maior correlação com a concentração de sedimentos em suspensão no rio Urucuia, sendo, respectivamente, de 0,546, 0,587 e 0,466.

Abstract

Studies about solid discharge on water bodies are important for water resource management, as sediments directly affect water quality and reservoirs siltation. Since the concentration of suspended  sediments  is  related  to  spectral  behavior,  products  obtained  by  orbital  remote sensing can corroborate research on hydrosedimentological dynamics in rivers. The Urucuia river is an important tributary along the left bank of São Francisco River in the northwestern mesoregion of Minas Gerais. In this context, the objective of the present study was to analyze the hydrosedimentological dynamics of the Urucuia river watershed considering field data  as well as the applicability of TM sensor-Landsat 5 to predict suspended load concentration. The results showed that the average rainfall in the basin is 1,305.4 mm, with an annual outflow of 314.9  mm.    A  sediment  discharge  curve  with  r²  equal  to  0.88  was  obtained  from  monitored flow and suspended sediment data from the Arinos-Montante station. The specific production of  supended  sediment    was  classified as  “moderate”,  being  95.1  Mg.km-2.year-1.  Landsat  5 bands 2, 3 and 4 are the ones that present the highest correlation with the suspended sediment concentration in Urucuia River, being, respectively, 0.546, 0.587 and 0.466.

A preservação e recuperação dos mananciais são objetivos básicos quanto aos recursos hídricos urbanos, sendo previstos nos planos de saneamento municipais e nos planos diretores.  O presente trabalho tem por objetivo avaliar a aplicação de um Protocolo de Avaliação Rápida (PAR) em mananciais urbanos, realizado por pessoas sem formação técnica na área de análise da qualidade de água, e validá-lo como ferramenta de diagnóstico ambiental para o planejamento e monitoramento das ações de recuperação de áreas degradadas e manutenção dos recursos hídricos. Foram avaliados 25 trechos em 10 mananciais de 4 localidades do Pontal do Triângulo Mineiro por meio de um PAR. Os resultados obtidos revelaram que em 96,0% das situações experimentadas, não se verificou diferença significativa entre os resultados do PAR aplicado por pessoas leigas ou técnicas. Os resultados também permitiram não só o mapeamento de trechos de mananciais prioritários para ações de recuperação ambiental como também permitiu um ranking de cursos d´água prioritários em cada localidade estudada. Os resultados validaram o PAR aplicado como uma ferramenta útil para a gestão de recursos hídricos, especialmente para municípios de pequeno porte onde os recursos financeiros, logísticos e humanos são bastante reduzidos.

Desafios da gestão integrada de recursos hídricos no Brasil e Europa
Authors: Padovesi-Fonseca Claudia , Faria Rafaela Silva de
Published: June 2023

No Brasil as águas são classificadas de acordo com suas condições ambientais e de saúde e associadas aos diversos usos. Podem ser desde classes especiais, quando não alteradas por atividades humanas, bem como adequadas para abastecimento e outros fins, e até somente usadas para navegação. A Diretiva Quadro da Água Europeia (DQAE), por sua vez, tem como objetivo principal alcançar o bom estado ecológico para os corpos hídricos. O enquadramento de corpos hídricos, como instrumento diretamente ligado com a qualidade e quantidade da água, possui uma certa comodidade na elaboração de diagnósticos, na definição dos parâmetros base e na preparação de cenários. Entretanto, há ainda carência de informações nos processos de concessão de outorgas e licenças ambientais. Este artigo avalia o uso de diretrizes europeia como itens complementares da gestão hídrica brasileira nas formas de enquadramento de corpos hídricos no Brasil. A integração das diretrizes de gestão de recursos hídricos brasileiro e europeu fortalece elos responsáveis da sociedade com os recursos ambientais, com a efetiva aplicação dos princípios de participação comunitária e a proteção ecológica das águas.
Diagnóstico socioambiental da microbacia Anhumas no município de Pouso Alegre - MG
Authors: Balbino Joyce da Silva , Braz Farley Soares , Monteiro Vanessa da Fontoura Custódio
Published: June 2023

A intensa atividade antrópica, como uso incorreto do solo, agricultura, pecuária, falta de saneamento básico e desmatamento, provoca incontáveis problemas em bacias hidrográficas, comprometendo o equilíbrio dos ecossistemas, a qualidade da água, e, consequentemente, a saúde e o bem-estar da população. Para assegurar a conservação nessas áreas, é preciso adquirir conhecimentos sobre aspectos socioambientais, desde escalas menores, como microbacias. Diante disso, objetivou-se realizar um diagnóstico socioambiental da microbacia Anhumas, inserida na sub-bacia do Rio Mandu, em Pouso Alegre - MG. O instrumento de coleta de dados foi um questionário aplicado aos moradores maiores de 18 anos. O questionário foi respondido por 80 moradores, sendo um representante de cada propriedade rural visitada. Verificou-se que a maioria das propriedades possui cisternas instaladas, que é um modelo de captação de água sustentável. A baixa utilização de mina d’água e a ocorrência de nascentes somente em 22,5% das propriedades revela a importância de ações de educação ambiental na região sobre a preservação de nascentes, visto que nem todas as propriedades possuem Área de Proteção Permanente conservadas. Em áreas rurais brasileiras, é comum a adoção de sistemas de coleta ou tratamento do esgoto mais simples, como fossa séptica e até mesmo sistemas inadequados, como fossas rudimentares. Verifica-se precariedade nos tratamentos de efluentes gerados na microbacia Anhumas, com maior utilização fossa rudimentar, o que provoca danos ao meio ambiente e à saúde pública. Os resultados obtidos neste trabalho podem subsidiar projetos e políticas públicas sobre recursos hídricos, restauração florestal, saneamento básico e agricultura sustentáveis na região.

Olfaction, body mass index, and quality of life with cystic fibrosis combination therapy
Authors: Tervo Jeremy P. , DiMango Emily , Gudis David A. , Keating Claire , Zhang Yuan , Leu Cheng‐Shiun , Altman Kimberly , Vilarello Brandon , Jacobson Patricia , Overdevest Jonathan B.
Published: June 2023

Background

Triple‐combination therapy of elexacaftor‐tezacaftor‐ivacaftor (ETI) has been shown to reduce morbidity and mortality in people with cystic fibrosis (PwCF). Although patient body mass index (BMI) favorably increases with ETI treatment, factors contributing to this improvement are poorly characterized. Olfaction contributes to appetite stimulation and anticipation of eating, where higher rates of olfactory impairment (OI) in PwCF may contribute to malnutrition and BMI instability in this population.

Methods

The authors performed a prospective cohort study analyzing 41 CF patient responses to the Cystic Fibrosis Questionnaire‐Revised (CFQR) and the 22‐Item Sino‐Nasal Outcome Test (SNOT‐22) and used generalized estimating equations to understand the change in survey variables from being untreated (baseline) to undergoing 3 months of ETI therapy (follow‐up).

Results

Patients reported significant improvement in their sense of smell at follow‐up (p = 0.0036). Their improvements in sense of smell were not confounded by changes in rhinologic or extranasal rhinologic symptoms. Self‐reported quality of life (QoL) improved after 3 months of ETI therapy (p = < 0.0001) as did BMI (p = < 0.0001), but improved sense of smell did not independently mediate these changes in QoL and BMI.

Conclusion

Our results support the impression that ETI therapy improves CF‐associated rhinologic symptoms and reverses OI, while contributing to improvement in rhinologic QoL. Sense of smell is not an independent mediator of improved QoL and BMI in this population, suggesting that other factors may have a stronger role in these realms. However, given the subjective improvement in sense of smell, additional evaluation of OI using psychophysical chemosensory assessment will clarify the connection between olfaction, BMI, and QoL in PwCF.

Medline, Cochrane and Embase databases were searched from inception to 31 July 2022. Two investigators independently reviewed and screened trials comparing antidiabetic drugs with no antidiabetic drugs, placebo, or other active antidiabetic drugs on cognitive outcomes in T2DM. Data were analysed using meta‐analysis and network meta‐analysis. Twenty‐seven studies met the inclusion criteria, including 3 randomised controlled trials, 19 cohort studies and 5 case‐control studies. Compared with non‐user, SGLT‐2i (OR 0.41 [95% CI 0.22–0.76]), GLP‐1RA (OR 0.34 [95% CI 0.14–0.85]), thiazolidinedione (OR 0.60 [95% CI 0.51–0.69]), and DPP‐4i (OR 0.78 [95% CI 0.61–0.99]) users had a decreased risk of dementia, whereas sulfonylurea (OR 1.43 [95% CI 1.11–1.82]) increased dementia risk. Network meta‐analysis showed that SGLT‐2i was most likely to rank best (SUCRA = 94.4%), GLP‐1 RA second best (SUCRA = 92.7%), thiazolidinedione third best (SUCRA = 74.7%) and DPP‐4i fourth best (SUCRA = 54.9%), while sulfonylurea second worst (SUCRA = 20.0%) for decreasing dementia outcomes, by synthesising evidence from direct and indirect comparisons of multiple intervention. Evidence suggests the effects of SGLT‐2i ≈ GLP‐1 RAs > thiazolidinedione > DPP‐4i for delaying cognitive impairment, dementia and AD outcomes, whereas sulfonylurea was associated with the highest risk. These findings provide evidence for evaluating the optional treatment for clinical practice.

Objective

The aim of this study was examining the efficacy of the Maudsley Model of Anorexia Nervosa Treatment for Adolescents and Young Adults (MANTRa) compared to individual psychotherapy that can be considered as standard in Austria (TAU‐O).

Method

In this cohort study, 92 patients between 13 and 21 years suffering from full‐syndrome, atypical or weight‐restored anorexia nervosa (AN) received either 24–34 individual MANTRa sessions (n = 45) or TAU‐O (n = 47). Outcome variables were age‐ and sex‐related BMI, eating disorder and comorbid psychopathology at 6‐, 12‐ and 18‐month post baseline as well as acceptability of treatment and therapeutic alliance.

Results

Both treatments resulted in significant improvements in age‐ and sex related BMI and reductions in eating disorder and comorbid psychopathology over time with significant differences between groups in favour of MANTRa. The percentage of participants with fully remitted AN was significantly higher in the MANTRa group compared to TAU‐O at 18‐month follow‐up (MANTRa: 46% vs. TAU‐O: 16%, p = 0.006). Satisfaction with both treatments was high.

Conclusions

MANTRa is an effective treatment programme for adolescents and young adults with AN. Randomised controlled trials comparing MANTRa with existing treatments are necessary.

Trial registration

The trial was registered at clinicaltrials.gov (Identifier: NCT03535714).

Recent reports suggest that salidroside protects cardiomyocytes from oxidative injury and stimulates glucose uptake by skeletal muscle cells. Despite these findings, the therapeutic potential of salidroside in the treatment of obesity and insulin resistance remains uncertain and requires further investigation. In the present study, the treatment effect of salidroside on the onset and development of the obese phenotype and insulin resistance as well as the underlying mechanisms was investigated using long‐term high‐fat diet‐induced obese mice supplemented with salidroside. We used biochemical kits to determine serum biochemical parameters (including triacylglycerol, total cholesterol, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol, fasting glucose, and insulin). The results show that salidroside‐supplemented animals showed better glucose tolerance and insulin sensitivity, decreased blood lipids, and weight gain (p < .05). Protein expression of p‐Nrf2 and Nrf2 was analyzed by western blotting, and the mRNA levels of thermogenic‐related genes (Ucp1, Pgc1a, Prdm16, and Cidea) were detected by quantitative RT‐PCR. The results show an improvement in lipid peroxidation and Nrf2/ARE signaling, as well as an increased expression of the Ucp1, Pgc1a, Prdm16, and Cidea (p < .05). Our evidence suggests that salidroside alleviates diet‐induced obesity and insulin resistance potentially by activating Nrf2/ARE pathway and enhancing the thermogenesis of adipose tissues. This induction represents a potential technique for the management of comorbidities related to obesity and its prevention.
Australian medical radiation practitioners perspectives of continuing professional development: An online cross‐sectional study
Authors: Morgan Tanya , Ku Min , Berg Melissa , Halkett Georgia KB
Published: June 2023

Introduction

Continuing professional development (CPD) is mandatory for registered Australian medical radiation practitioners (MRPs) to maintain competence in their respective scopes of practice. The aim of this study was to explore MRPs attitudes, opinions and satisfaction towards CPD activities offered by the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT).

Methods

An online cross‐sectional survey was emailed to 6398 ASMIRT members and included questions on: demographics, ASMIRT CPD activities, learning mode preferences, barriers and perceptions of CPD outcomes. Data were analysed using descriptive statistics and chi‐square tests.

Results

The survey was completed by 1018 MRPs. While MRPs were satisfied with face‐to‐face CPD quality (n = 540, 58.1%) and provision (n = 492, 55.3%), they were dissatisfied with the quantity of online CPD activities (n = 577, 65.1%) delivered by ASMIRT. Online learning was the most preferred mode of CPD delivery (n = 749, 74.2%), followed by face‐to‐face (n = 643, 64.0%) and collaborative learning (n = 539, 53.4%). Younger participants (19–35 years) had positive opinions regarding ASMIRT CPD activities and outcomes. Access to professional development leave (PDL) supported achievement of mandatory CPD requirements (P < 0.001). Lack of time, lack of access and workload were the highest ranked barriers preventing CPD participation. Rural/remote MRPs were dissatisfied with availability (P = 0.023), access (P < 0.001) and adequacy of ASMIRT provided CPD (P < 0.01) and were more likely to encounter barriers to CPD participation (P < 0.001).

Conclusions

Many MRPs experienced barriers which prevented them from participating in CPD. Provision of more online CPD activities by ASMIRT and access to PDL can assist. Future improvements will ensure MRPs remain motivated to engage in CPD to improve clinical skills, patient safety and health outcomes.
Role of methyldioxy radical chemistry in high‐pressure methane combustion in CO2
Authors: Harman‐Thomas James M. , Ingham Derek B. , Hughes Kevin J. , Pourkashanian Mohamed
Published: June 2023

The combustion chambers of direct‐fired supercritical CO2 power plants operate at pressures of approximately 300 bar and CO2 dilutions of up to 96%. The rate coefficients used in existing chemical kinetic mechanisms are validated for much lower pressures and much smaller concentrations of CO2. Recently, the UoS sCO2 1.0 and UoS sCO2 2.0 mechanisms have been developed to better predict ignition delay time (IDT) data from shock tube studies at pressures from 1 to 260 bar in various CO2‐containing bath gas compositions. The chemistry of the methyldioxy radical (CH3O2) has been identified as an essential combustion intermediate for methane combustion above 100 bar, where mechanisms missing this species begin to vastly overpredict the IDT. The current literature available on CH3O2 is very limited and often concerned with atmospheric chemistry and low‐pressure, low‐temperature combustion. This means that the rate coefficients used in UoS sCO2 2.0 are commonly determined at sub‐atmospheric pressures and temperatures below 1000 K with some rate coefficients being over 30 years old. In this work, the rate coefficients of new potential CH3O2 reactions are added to the current mechanism to create UoS sCO2 2.1 It is shown that the influence of CH3O2 on the IDT is greatest at high pressures and low temperatures. It has also been demonstrated that CO2 has very little effect on the chemistry of CH3O2 at 300 bar meaning that CH3O2 rate coefficients can be determined in other bath gases, reducing the impact of non‐ideal effects such as bifurcation when studying in a CO2 bath gas. The updated UoS sCO2 2.1 mechanism is then compared to high‐pressure IDT data and the most important reactions which require reinvestigation have been identified as the essential next steps in understanding high‐pressure methane combustion.

Published: June 2023

Background

Nutrition support professionals are tasked with estimating energy requirements for critically ill patients. Estimating energy leads to suboptimal feeding practices and adverse outcomes. Indirect calorimetry (IC) is the gold standard for determining energy expenditure. However, access is limited, so clinicians must rely on predictive equations.

Methods

A retrospective chart review of critically ill patients who underwent IC in 2019 was conducted. The Mifflin–St Jeor equation (MSJ), Penn State University equation (PSU), and weight‐based nomograms were calculated using admission weights. Demographic, anthropometric, and IC data were extracted from the medical record. Data were stratified by body mass index (BMI) classifications, and relationships between estimated energy requirements and IC were compared.

Results

Participants (N = 326) were included. Median age was 59.2 years, and BMI was 30.1. The MSJ and PSU were positively correlated with IC in all BMI classes (all P < 0.001). Median measured energy expenditure was 2004 kcal/day, which was 1.1‐fold greater than PSU, 1.2‐fold greater than MSJ, and 1.3‐fold greater than weight‐based nomograms (all P < 0.001).

Conclusion

Despite the significant relationships between measured and estimated energy requirements, the significant fold‐differences suggest that using predictive equations leads to significant underfeeding, which may result in poor clinical outcomes. Clinicians should rely on IC when available, and increased training in the interpretation of IC is warranted. In the absence of IC, the use of admission weight in weight‐based nomograms could serve as a surrogate, as these calculations provided the closest estimate to IC in participants with normal weight and overweight, but not obesity.

Published: June 2023

Background

Protein and phosphorus intake, which affect chronic kidney disease (CKD), is assessed using cumbersome food diaries. Therefore, more straightforward and accurate methods of assessing protein and phosphorus intake are needed. We decided to investigate the nutrition status and dietary protein and phosphorus intake of patients with stages 3, 4, 5, or 5D CKD.

Methods

This cross‐sectional survey included outpatients with CKD at seven class A tertiary hospitals in Beijing, Shanghai, Sichuan, Shandong, Liaoning, and Guangdong in China. Protein and phosphorus intake levels were calculated using 3‐day food records. Protein levels and calcium and phosphorus serum concentrations were measured; urinary urea nitrogen was determined using a 24‐h urine test. Protein and phosphorus intakes were calculated using the Maroni and Boaz formulas, respectively. The calculated values were compared with the recorded dietary intakes. An equation that regressed phosphorus intake on protein intake was constructed.

Results

The average recorded energy and protein intake was 1637.5 ± 595.74 kcal/day and 56.97 ± 25.25 g/day, respectively. Overall, 68.8% of patients had a good nutrition status (grade A on the Subjective Global Assessment). The correlation coefficient between protein intake and calculated intake was 0.145 (P = 0.376) and that between phosphorus intake and calculated intake was 0.713 (P < 0.001).

Conclusion

Protein and phosphorus intakes correlated linearly. Chinese patients with stage 3–5 CKD had low daily energy intake but high protein intake. Malnutrition was present in 31.2% of patients with CKD. The phosphorus intake could be estimated from the protein intake.
