Objectives

To determine whether the maternal plasma concentrations of cytokines are higher in pregnant women with postpartum hemorrhage (PPH) compared to pregnant women without PPH.

Methods

A retrospective case-control study included 36 women with PPH and 72 matched controls. Cases and controls were matched for gestational age at delivery, labor status, delivery route, parity, and year of sample collection. Maternal plasma samples were collected up to 3 days prior to delivery. Comparison of the plasma concentrations of 29 cytokines was performed by using linear mixed-effects models and included adjustment for covariates and multiple testing. A false discovery rate adjusted p-value <0.1 was used to infer significance. Random forest models with evaluation by leave-one-out and 9-fold cross-validation were used to assess the combined value of the proteins in predicting PPH.

Results

Concentrations of interleukin (IL)-16, IL-6, IL-12/IL-23p40, monocyte chemotactic protein 1 (MCP-1), and IL-1β were significantly higher in PPH than in the control group. This difference remained significant after adjustment for maternal age, clinical chorioamnionitis, and preeclampsia. Multi-protein random forest proteomics models had moderate cross-validated accuracy for prediction of PPH [area under the ROC curve, 0.69 (0.58–0.81) by leave-one-out cross validation and 0.73 (0.65–0.81) by 9-fold cross-validation], and the inclusion of clinical and demographic information did not increase the prediction performance.

Conclusions

Pregnant women with severe PPH had higher median maternal plasma concentrations of IL-16, IL-6, IL-12/IL-23p40, MCP-1, and IL-1β than patients without PPH. These cytokines could serve as biomarkers or their pathways may be therapeutic targets.

Published: June 2022

Air pollution has emerged as a serious threat to human health due to close association with spectrum of chronic ailments including cardiovascular disorders, respiratory diseases, nervous system dysfunctions, diabetes and cancer. Exposure to air-borne pollutants along with poor eating behaviours and inferior dietary quality irreversibly impacts epigenomic landscape, leading to aberrant transcriptional control of gene expression which is central to patho-physiology of non-communicable diseases. It is assumed that nutriepigenomic interventions such as vitamins can control such adverse effects through their immediate action on mitochondrial epigenomic-axis. Importantly, the exhaustive clinical utility of vitamins-interceded epigenetic synchronization is not well characterized. Therefore, improving the current limitations linked to stability and bioavailability issues in vitamin formulations is highly warranted. The present review not only sums up the available data on the role of vitamins as potential epigenetic modifiers but also discusses the importance of nano-engineered vitamins as potential epidrugs for dietary and pharmacological intervention to mitigate the long-term effects of air pollution toxicity.
Functional changes in brain oscillations in dementia: a review
Authors: Giustiniani Andreina , Danesin Laura , Bozzetto Beatrice , Macina AnnaRita , Benavides-Varela Silvia , Burgio Francesca
Published: June 2022

A growing body of evidence indicates that several characteristics of electroencephalography (EEG) and magnetoencephalography (MEG) play a functional role in cognition and could be linked to the progression of cognitive decline in some neurological diseases such as dementia. The present paper reviews previous studies investigating changes in brain oscillations associated to the most common types of dementia, namely Alzheimer’s disease (AD), frontotemporal degeneration (FTD), and vascular dementia (VaD), with the aim of identifying pathology-specific patterns of alterations and supporting differential diagnosis in clinical practice. The included studies analysed changes in frequency power, functional connectivity, and event-related potentials, as well as the relationship between electrophysiological changes and cognitive deficits. Current evidence suggests that an increase in slow wave activity (i.e., theta and delta) as well as a general reduction in the power of faster frequency bands (i.e., alpha and beta) characterizes AD, VaD, and FTD. Additionally, compared to healthy controls, AD exhibits alteration in latencies and amplitudes of the most common event related potentials. In the reviewed studies, these changes generally correlate with performances in many cognitive tests. In conclusion, particularly in AD, neurophysiological changes can be reliable early markers of dementia.

The present study reveals the proliferation of cytokines in treated and non- treated broilers consisting of IFN- γ, IL-1, IL-2, IL-4, IL-6, TNF and TGF. The CD4 count in the treated and non- treated broilers orally administered with various developmental stages of the parasite reached a peak on day 10 at primary; secondary and day 24 at tertiary infections. There was significant difference in the CD4 cell count between groups of the infected broiler chickens (p < 0.05). The current study observed a relationship between the different developmental stages of the parasite and lymphocytes response. Broiler chickens infected with sporulated oocyst (sporozoites) and merozoites treated and non-treated gave high CD4 T- lymphocyte numbers than the other groups throughout the experimental periods.

Nowadays with developing and city growth, also city systems need to be update and developing parallel to expand of cities. So it is wisely that getting forward the network reforming and city systems with needs and today’s conditions of society and city. Public transportation system is one of the largest and the most complex city systems that has very important rule on speediness of citizen transition; so reforming and making changes for optimization the efficiency amount of system is not easily possible. In this thesis has been paid attention to introduce and determine the measure of accessibility indices affect to public transportation network with walking mode and present a method for developing feeder network of public transportation system. We calculated the coefficients of accessibility indices by Sampling Statistical in city of Tehran. In this method uses three algorithms for evaluating time and comforting applicants travel and also present and taking result a model for reforming location of public transportation stations and a model for designing feeder routes that with investigating and comparing work has done.

Primogeniture in Turkish Family Owned Businesses: An Examination of Daughter Succession, the Impact of National Culture on Gendered Norms and Leadership Challenge
Authors: Ozdemir Ozlem , Harris Phil
Published: June 2022

Family owned and controlled businesses, which may be owned, controlled or operated by various family members, account for an enormous percentage of global employment, revenues and GDP. Although the majority of well-known companies are family owned, research indicates that unfortunately, only thirty percent of family businesses survive to the second generation. Therefore, successful transfer of the business to the next generation is an important issue for the family business literature. However, although succession is a vital issue for Family Owned Businesses (FOBs), the process is unfortunately very gender biased in most societies, with boys being generally favoured over girls so daughters are always excluded as candidates and other women are seldom considered as successors in family businesses. In many cases, especially in certain cultures, female members of the next generation are not even perceived as a viable option. Even in today’s rapidly changing business climate, primogeniture continues to dominate the value system of family businesses. Primogeniture is an accepted approach to family business succession planning; daughters are only considered for family business succession when all descendants are female or the daughter is the first born. This study aims to identify the reasons behind the primogeniture in Turkish FOBs. The objectives of the study were to examine the key factors identified by the incumbents related with the primogeniture. In this research study, an interpretive methodology was adopted to explore, interpret and to understand meanings of knowledge. For this research, qualitative data were gathered via in-depth open-ended interviews with 20 male FOB owners who have at least one daughter and 20 daughters working at their FOB with their fathers. The questions were designed to measure different facets of FOB demographics and culture to understand their effects on the selection process within Turkish FOBs and gender norms in the context of FOB norms, which influence both family members and the business it. This study investigated daughters’ succession in FOBs in Turkey, a developing country where women are less likely than men to engage in entrepreneurial activities and show that gendered norms are still considered when choosing the successor, in other word, primogeniture still dominates the family business succession process.

How TRUST is both the driver and inhibitor in not-for-profit sector growth strategies: The "Lived" experience of Merger and Acquisition
Authors: Barnes Lisa
Published: June 2022

This research is a case study based on the "lived experience” of two not-for-profit organisations wanting to create synergies and efficiencies in back office operations and to increase the offerings of services to existing clients by joining together as one business unit. This research has followed the different stages of the proposed merger or acquisition from the initial signing of the Memorandum of Agreement (MOA), to the strategic planning for the new entity including the potential organisational structure, board structure and executive team recruitment. The negotiations have varied from the rejection of a takeover, to the proposal of a merger, to the eventual decision for the larger organisation to “acquire” the smaller organisation. These decisions were deliberated at great length by both organisations, but the clear driver in all negotiations was TRUST. Trust that at all times the outcomes should benefit clients, trust that the new Board would be represented in equal parts by both of the organisations and trust that the new senior executive team of the single entity would utilise the efficiencies gained to sustain the organisation. But this trust also became an inhibitor at times, where trust was used as an excuse to not carry out all due diligence governance processes (DDGP). This lived experience has shown that Trust is indeed an important factor in any proposed merger or acquisition but will never replace DDGP. In fact DDGP enhanced trust, and enabled for more transparent decisions to be reached by both parties at the negotiation table. The not-forprofit sector can learn a great deal from this case study that shows the benefits of societal needs of their clients in aged care, disability and transport by a merger or acquisition. It should be used by other not-for-profit organisations to put into practice strategic merger and acquisition processes to create an organisation that is run efficiently and for the benefit of their clients, with a combination of trust and DDGP.

Family and Business are Important Parts in Every Family Enterprise
Authors: Franjic Sinisa
Published: June 2022

An important part of any economy is family-owned enterprises, especially in developed countries, which have a long tradition of entrepreneurship and private ownership. A family business is a combination of two different terms - family and business. On the one hand, a family is a group of people in which a person is born, grows up, who also cares for and protects him until the moment he creates his own family, in which the same cycle repeats itself over and over again. The enterprise, on the other hand, is also a group of people, but it is bound by the interest of pursuing a profit-making activity that ensures the employees’ daily existence, and the owners of these companies achieve their ultimate goal, which is to maximize personal wealth. The aim of this paper is focusing the attention of future entrepreneurs on some of the most important components of any successful family business.

Published: June 2022

Software products are available through which motifs of visual images of folk costumes can be converted into a vector format suitable for making them on knitting and embroidery machines [1]. In order to reach the final decision - which elements are to be embedded in modern clothing and textiles - a number of steps are sometimes required, which are challenging the designer - studying fashion trends, finding appropriate items that have not been applied by others to new clothes and textile designs are proposed to be attractive to the consumer and competitive in the over-stretched fabric and garment market [3]. To support this activity, software products and algorithms for analysis of colors and shapes have been developed and tested [1]. An algorithm was proposed in present work for obtaining elements of folk costume, suitable for conducting surveys in their application of modern textiles.

Published: June 2022

Das Treffen von Strategieentscheidungen in einem VUCA-Umfeld ist für Unternehmen herausfordernd. Der bedeutende Einfluss vom „Zufall“ kann dabei nicht mit eindimensionalen Strategiebewertungen, sondern nur mit szenariobasierten Risikoanalysen der strategischen Zielgrößen adäquat abgebildet werden. Hierbei überzeugt die Monte-Carlo-Simulation, die neben der Risikobewertung von Finanzprodukten ebenso vorteilhaft für strategische Initiativen einzusetzen ist.
Status quo und Ausgabenprojektionen der Beamtenversorgung
Authors: Raffelhüschen Bernd , Kohlstruck Tobias
Published: June 2022

Da die Beamtenpopulation deutlich älter als die Gesamtbevölkerung ist, gehen die kohortenstarken Jahrgänge bereits in den Ruhestand. Allein in den letzten zehn Jahren haben sich die jährlichen Versorgungsausgaben der Gebietskörperschaften um 50 % erhöht, wovon insbesondere die (westdeutschen) Bundesländer betroffen sind. In den kommenden Jahren ist mit einem weiteren Anstieg der Versorgungsausgaben zu rechnen, wobei sich der rein demografische Effekt bis Ende des Jahrzehnts abschwächen wird. Auch wenn die Altersstruktur der Beamten sowie verfassungsrechtliche Vorgaben einer schnellen Verringerung der Versorgungsausgaben entgegenstehen, sollte der Staat in Zukunft auf eine restriktivere Verbeamtungspolitik mit Augenmaß und eine deutlich stärkere Kapitaldeckung der Versorgungszusagen setzen, um die intergenerative Ungleichverteilung zu verringern.

Wie man Künstliche Intelligenz regulieren sollte
Authors: Wagner Gert G.
Published: June 2022

Die in den Feuilletons beliebte Spekulation, wann Künstliche Intelligenz (KI) Bewusstsein erlangen wird und dadurch das Menschsein fundamental bedrohen wird, täuscht darüber hinweg, dass KI bereits jetzt besser kontrolliert und reguliert werden sollte, als das tatsächlich der Fall ist. Die Fähigkeiten der vorhandenen „schwachen“ KI sind so groß, dass wir nicht zögern sollten, sie effektiv zu kontrollieren. Und das geht ohne Weiteres, wir müssen es nur wollen. Denn KI ist keineswegs „selbstlernend“, sondern sie wird von Menschen „trainiert.“ Zur effektiven Kontrolle notwendig ist lediglich ein systematischer Zugang zu den Daten, mit denen KI „trainiert“ wird und die sie produziert. Dann kann KI, ohne dass man ihre Software öffentlich machen muss, getestet werden. Und für diese Tests muss auch institutionalisierte Forschungskapazität aufgebaut werden.
Nikolai Tsikura, the first new martyr of Omsk: an investigation of the murder of the member of the church at the beginning of the Civil war in Russia
Authors: Sushko Aleksey
Published: June 2022

The article analyzes the events in Omsk on February 15-22, 1918, when an attempt by the regional Soviet authorities to implement the "Decree on the separation of church from state and school from church" led to riots in, Soviet historiography called the "priest's rebellion". In the course of these events, the novice and housekeeper of the bishop's house, Nikolai Tsikura, was killed and later canonized by the Russian Orthodox Church. The aim of the work is to analyze the circumstances of the death of Nikolai Tsikura in the context of the events of the Civil War that broke out in Russia. Along with published reports in periodicals and published and unpublished memoirs, one of the key evidence of the topic under consideration is the act record of the death of Nikolai Tsikura, stored in the Historical Archive of the Omsk Region. The article introduces into scientific circulation a brief description of the personality of Nikolai Tsikura, given to him in connection with the events of the “priest’s rebellion” in the memoirs of Omskovite M.A. Stolpovsky, who personally knew him. After analyzing two points of view on the cause of the murder of Nikolai Tsikura (he defended the bishop during the arrest or was killed for no apparent reason), the author notes the absence of a source that allows to unambiguously answer that question. When analyzing the circumstances of the death of Nikolai Tsikura, special attention is paid to the fact that the bells rang by killed priest triggered the mass unrest in Omsk, brought the people out into the streets who defended Bishop Sylvester and other arrested priests from possible reprisals and postponed for a month the implementation in Omsk of the “Decree on the separation of church from state and school from church.” It is emphasized that the canonization of Nikolai Tsikura in In 2000, continued the church tradition of venerating him as a holy new martyr started in 1918 at the Local Council of the Russian Orthodox Church.
Development of the conservative opinions of the church in Orel diocese as to the freedom of conscience after the Missionary congress of 1901
Authors: Balyko Timofey
Published: June 2022

The article is devoted to the topic of freedom of conscience, which by the beginning of the twentieth century had become one of the main topics in Russian church and public thought. The relevant discussion was largely initiated by a speech in September 1901 at the Missionary Congress in Orel by the leader of the nobility of the Orel province, M. A. Stakhovich, who proposed introducing freedom of conscience in Russia and abolishing criminal penalties for falling away from the Orthodox Church. This event has been repeatedly considered in the context of the all-Russian controversy that has arisen, but the consequences of Stakhovich's speech in the Oryol diocese itself have not been subjected to scientific study before. The author of the article managed to establish the fact of the activation of conservative church thought in the Oryol diocese at the end of 1901 and the clear formulation of the positions of the Oryol conservatives on the introduction of freedom of conscience and other liberal freedoms, which were a threat to the existence of the church-state union and the Russian Orthodox state. Special attention in the study is paid to attempts to blur the boundaries of the Church in the Orel diocese, to include "random persons" acting on a political order in church life. It also drew criticism from conservatives. After 1901, the manifestation of church conservative thought in the Orel diocese on these issues can be traced in a number of journalistic materials. This concerns, first of all, the period of the revolutionary years 1905-1907. and 1917, which indicates a certain stability of church conservative ideas in the Oryol diocese, the presence of these ideas of groups of supporters who became active at crucial moments in history.

Sobre a atualidade política da Teoria Crítica
Authors: Bunk Benjamin , Sobottka Emil A.
Published: June 2022

O objetivo deste texto, introdutório ao núcleo temático sobre a atualidade política da Teoria Crítica, é estabelecer um quadro referencial. Em um primeiro momento, coloca a questão da relação fundamental entre política, crítica e teoria social – atual já no tempo de Max Weber e na sua fundamentação das ciências sociais ao lado do político, a qual nunca perdeu a sua atualidade política. Em um segundo momento, por meio de uma retrospectiva histórica, são enfatizados aspectos fundamentais da forma de crítica da Teoria Crítica. Para tanto, recorremos a duas referências. Já Jean-Jacques Rousseau se ocupou da relação entre desigualdade e emancipação através de sua análise da alienação devida às condições sociais. Com Walter Benjamin a experiência com a política torna-se o ponto de partida para uma crítica da interconexão constitutiva entre o indivíduo e suas condições sociais. Ao assumir esses enfoques, a própria Teoria Crítica torna-se um instrumento para tornar o progressivo processo de sociação menos desigual e menos alienador – e a atualidade política permanente dessa escola de pensamento se torna evidente. Finalmente, sugerimos uma breve sistematização dos textos, em diálogo entre cientistas alemães e brasileiros, perguntando pelo lugar da política nas teorias sociais; pela relevância da política para diferentes teorias sociais atuais, notadamente pós-colonial e teoria crítica; por diagnósticos atuais de realidade feitos na perspectiva da Teoria Crítica.
Análisis energético en lecherías de la región pampeana Argentina. Parte 1. Flujos de energía
Authors: Gimenez Gustavo Daniel , Novaira Bruno Idelfonso , Marini Pablo Roberto
Published: June 2022

Introducción. La heterogeneidad de los sistemas agropecuarios dificulta evaluar su sustentabilidad, pues no existen herramientas que puedan aplicarse a la generalidad de los casos, con indicadores de fácil comprensión por los actores del medio. Una herramienta de uso posible es el análisis energético. Objetivos. Contextualizar la heterogeneidad de los modelos de producción primaria de leche, con base en flujogramas de energía. Materiales y métodos. Se trabajó con datos retrospectivos de nueve establecimientos comerciales de producción de leche en la Región Pampeana Argentina, durante el período comprendido entre julio de 2014 a junio de 2015. Estos se diferenciaron según variables como carga animal y nivel de suplementación alimentaria. Se utilizó la metodología de estudio de casos, con análisis energéticos para cada caso, configurándose para cada uno flujogramas y cuantificándose ingresos, egresos y eficiencia de uso de la energía. Resultados. Se determinó la existencia de tres tipos de sistemas: mixto lechero-agrícola con invernada (proceso de engorde), mixto lechero-agrícola y lechero puro con invernada. Los sistemas mixtos son importantes por el caudal energético que aportan la agricultura, para compensar la significativa pérdida de energía de los subsistemas de leche y carne; sin embargo, los sistemas ganaderos puros resultaron más eficientes en el uso de la energía, debido al menor consumo energético y a la producción forrajera. Conclusiones. El análisis energético resultó útil para caracterizar la heterogeneidad entre sistemas a partir de la construcción de flujogramas. También permitió evaluar aspectos sociales y ambientales, que en análisis tradicionales quedan excluidos; pero que, dado el volumen del flujo energético que proveen, motivan la necesidad de incluirlos en la contabilidad por su importancia para el proceso lechero y por el estrecho vínculo entre naturaleza y sociedad, asociado al complejo hombre-ecosistema.
Effects of local faith-actor engagement in the uptake and coverage of immunization in low- and middle-income countries: A literature review
Authors: Melillo Sara , Strachan Rebecca , O'Brien Carolyn J , Wonodi Chizoba , Bormet Mona , Fountain Doug
Published: June 2022

Introduction: Religious leaders are universally recognized as having an influence on immunization uptake and coverage in low- and middle-income countries (LMICs). Despite this, there is limited understanding of three questions: 1) how do religious leaders impact the uptake and coverage of immunization in LMICs? 2) what successful strategies exist for working with local faith actors to improve immunization acceptance? and 3) what evidence gaps exist in relation to faith engagement and immunization?
Methods: In January 2021, we searched PubMed and Google Scholar databases covering the period from January 1, 2011 to January 15, 2021 with key search terms related to faith engagement and immunization in peer-reviewed literature and conducted a gray literature review to answer these three questions. We excluded articles covering faith engagement and immunization in high-income countries, news articles, online blogs, social media postings, and articles in languages outside of English. Data were coded to guide thematic analysis.
Results: We found extensive evidence supporting the value of religious engagement for immunization promotion and acceptance in LMICs across faiths. However, there was limited rigorous evidence and examples of specific approaches for engaging local faith actors to strengthen immunization uptake in LMICs. As a result, there is a lack of widely shared knowledge of what works (or doesn’t) and successful models for engaging local faith actors. Additional current evidence gaps include: few rigorous study designs; a lack of vaccine hesitancy studies outside of Nigeria and Pakistan; and limited exploration of faith engagement and immunization in religions other than Islam and Christianity.
Conclusions: Our review findings reinforce the powerful role local faith actors play in diverse communities within LMICs in both promoting and inhibiting immunization uptake. The literature review comes at a critical time, given the urgent need to expand access to COVID-19 vaccination in LMICs. Findings from this review will advance understanding on how to more effectively engage local faith actors in promoting immunization campaigns and addressing vaccine hesitancy, which is more complex than expected. Further study is needed to understand how to most effectively counter vaccine hesitancy in different geographic, linguistic, and socio-cultural context.
On symplectic invariants of planar 3-webs
Authors: Konovenko Nadiia
Published: June 2022

The classical web geometry [1,3,4] studies invariants of foliation families with respect to pseudogroup of diffeomorphisms. Thus for the case of planar 3-webs the basic semi invariant is the Blaschke curvature, [2]. It is also curvature of the Chern connection [4] that are naturally associated with a planar 3-web.
In this paper we investigate invariants of planar 3-webs with respect to group of symplectic diffeomorphisms. We found the basic symplectic invariants of planar 3-webs that allow us to solve the symplectic equivalence problem for planar 3-webs in general position. The Lie-Tresse theorem, [4], gives the complete description of the field of rational symplectic differential invariants of planar 3-webs. We also give normal forms for homogeneous 3-webs, i.e. 3-webs having constant basic invariants.

Authors: Di Beo Luca , Prishlyak Alexandr Olegovich
Published: June 2022

We study flows on the Boy's surface. The Boy's surface is the image of the projective plane under a certain immersion into the three-dimensional Euclidean space. It has a natural stratification consisting of one 0-dimensional stratum (central point), three 1-dimensional strata (loops starting at this point), and four 2-dimensional strata (three of them are disks lying on the same plane as the 1-dimensional strata, and having the loops as boundaries). We found all 342 optimal Morse-Smale flows and all 80 optimal projective Morse-Smale flows on the Boy's surface.
A Study on Associations between the Exercise Habits and Subjective Health Perceptions of Adolescents in Area of Seoul: Focusing on Middle School Students
Authors: Lee Yoon-Ji , Kim Ha-Young
Published: June 2022

PURPOSE: To provide physical activity vitalization plans of exercise habits among adolescents by analyzing the association between the formation of proper exercise habits and subjective health perceptions.METHODS: This study analyzed exercise habits and subjective health perceptions of adolescents using the survey conducted in 2020 in the Korea Centers for Disease Control and Prevention.RESULTS: This study found that there were significant differences between happiness and health recognitions. In addition, the more days of aerobic exercise, high intensity exercise, and strength exercise led to higher levels of happiness recognition. Lastly, strength exercise for at least three times a week recognized themselves as being relatively healthier than those with different numbers of exercise days.CONCLUSIONS: This study concluded that exercise habits are positively related to the subjective health recognition and they felt that healthy life-long activity would be beneficial for the future lifestyle.
Effect of Circuit Type Neuromuscular Training on Strength, Power, and Functional Performance in MZ Generation
Authors: Lee Kwang-Jin
Published: June 2022

PURPOSE: This study aimed to investigate the effects of circuit-type neuromuscular training (CTNT) on strength, power, and functional performance among the MZ generation.METHODS: Twenty-eight participants were assigned to either the circuit-type neuromuscular training group (CTNTG, n=14) or the control group (CG, n=14). CTNT was performed for 50 minutes a day, 2–3 times a week, for 6 weeks. The CG only performed activities of daily living during the study period. Baseline and post measures included isometric muscular strength (knee flexion, knee extension, back flexion, back extension), vertical jump, 30 m sprint, T-agility, and Y-balance tests.RESULTS: The results showed that the CTNT had a positive effect on the improvement of knee flexion (p=.015), knee extension (p=.047), back extension (p=.003), vertical jump (p=.025), T-agility (p=.046), posteromedial (p=.031), posterolateral (p=.022), and composite score (p=.032).CONCLUSIONS: These findings can be a factor that the strength, power, and functional performance of MZ generation can be sufficiently improved through the CTNT program. This suggests that CTNT is the most appropriate exercise intervention method to improve the strength, power, and functional performance of the MZ generation.

Males (n=77,705) aged 18-65 years and females (n=84,641) were included. Three indices [I1=kg/m, I2=kg/m2/sup>, and I3=kg/m3] and I4 [I4=kg/ m2], which simply reduce the standard error of I1, were analyzed. Pearson's correlation analysis was conducted to determine an index that was highly correlated with weight and was independent of height. Furthermore, an index that was highly correlated with the body fat percentage was considered. The linear relationship between height and the indices was confirmed using regression analysis. The n value of the index (kg/mn), which provides the same value for all height ranges, was derived by regression analysis between weight and height.RESULTS: The correlation analysis between height and the indices described I2 (r=-.009, p<.05) as the most suitable for males. The I1 and I4 (r=-.049, p<.01) were appropriate for females. Weight showed a significant correlation with all indices. The association between body fat percentage and I3 showed a high correlation in both males (r=.722, p<.01) and females (r=.734, p<.01). Regression analyses represented I2 (B=-.005, p<.05) suitability for males. For females, I4 (B=.022, p<.01) was replaceable.CONCLUSIONS: The results of this study suggest that I2 (kg/m2) is appropriate for males. The I4 (kg/m2) was applicable to females. The I3 (kg/m3) showed the strongest correlation with body fat percentage in both males and females.

The Association between Maternal Folate Status and Childhood Obesity-Systematic Review and Meta-AnalysiPURPOSE: Maternal nutrition plays a crucial role in fetal growth and lifelong health outcomes. Folate is an essential methyl donor in the epigenetic programming of offspring. This review and meta-analysis was conducted to compile the evidence reported thus far to identify associations between maternal folate status and childhood obesity.METHODS: A keyword/reference search was performed in EBSCOhost and Web of Science databases. A CMA program was used for a meta-analysis to estimate the pooled effect of maternal folate status on childhood obesity in offspring and to examine the influence of moderating variables on the overall effect.RESULTS: Better maternal folate intake was associated with a lower risk of childhood obesity: the overall effect size (ES; Hedges’ g) was 0.168 (95% CI=0.075 to 0.260, p<.001; small effects; cf., Cohen’s criteria). Moderator analysis revealed that the ≥Q statistic for the age group was statistically significant (Qb=4.730, df=1. p=.030; heterogeneity of ES). In offspring <7 years and >7 years, the ES was 0.277 (95% CI=0.151, 0.404) and 0.089 (95% CI=-0.025, 0.202), respectively. The study design was a statistically significant variable (Qb=4.310, df=1. p=.038; heterogeneity of ES). In cohort studies, ES was 0.251 (95% CI=0.135, 0.367), whereas in randomized controlled trial group, ES was 0.062 (95% CI=-0.073, 0.197).CONCLUSIONS: Maternal folate intake significantly affects childhood obesity, and the effect of maternal folate status is stronger inchildren younger than 7 years.

PURPOSE: This cross-sectional study examined the combined effects of nutritional health risk and physical activity on depressive symptoms in a representative sample of older adults aged 65 years and older (4,116 men and 5,154 women) from the 2020 Korea Longitudinal Study of Aging.METHODS: Nutritional health risk was categorized as good, moderate, and high according to the Nutrition Screening Initiative. Physical activity was assessed using a questionnaire. Depression was assessed using the Short Form of Geriatric Depression Scale (SGDS).RESULTS: There were significant age differences (p<.001), education level (p<.001), marital status (p<.001), and SDGS (p<.001) according to nutritional health risk or physical activity status. In particular, a general linear model (GLM) showed a significant interaction (R2=.239, F(2,9849)=5.582, p<.004) between nutritional health risk and physical activity on SGDS-based depressive symptoms. The antidepressant effect of regular physical activity was observed in individuals with good or moderate nutritional health risks. However, such beneficial effects of physical activity were not observed in individuals with high nutritional health risks.CONCLUSIONS: The current findings of this study suggest that both good nutrition and physical activity for mental health should be emphasized in older adults, with a greater focus on nutrition for those with a high nutritional health risk.

RESUMO Objetivo A cetamina apresenta-se como uma alternativa promissora contra a depressão resistente ao tratamento (DRT), no entanto o conhecimento de sua aplicação como antidepressivo ainda é restrito. Diante disso, objetivou-se investigar sua eficácia em pacientes com DRT. Métodos A busca da literatura foi efetuada na base de dados MedLine. Os critérios de inclusão foram: estudos clínicos controlados e randomizados dos últimos cinco anos e em inglês. Excluímos os artigos que não responderam à pergunta PICO e aqueles com tamanho de amostra e metodologia de estudo destoantes, quando comparados aos ensaios que basearam esta revisão. Resultados Considerando uma amostra final de seis artigos, observou-se uma melhor resposta à cetamina (principalmente em ganho de humor), quando comparada ao tratamento convencional contra a DRT. Já com sua primeira infusão, na dose de 0,5 mg/kg, foi possível perceber seus efeitos antidepressivos. A manutenção desses efeitos parece ser obtida com a administração de 0,5 mg/kg do medicamento, três vezes por semana. Por outro lado, a redução de tal dosagem pode diminuir ou anular os efeitos. Conclusões O uso da cetamina apresentou resultados efetivos na melhora do quadro de DRT, com efeitos adversos de pequena gravidade e de fácil controle. Entretanto, outros estudos, com amostras maiores e métodos diferentes, são necessários, para uma conclusão de maior consistência.

RESUMO Objetivo A qualidade de vida sexual abarca a satisfação sexual e com a parceria, a expressão de desejos e valores sexuais, a boa imagem corporal, além de questões de ordem física, comportamentais, psicológicas e emocionais que afetam a sexualidade. Não há instrumentos confiáveis e válidos para avaliar a qualidade de vida sexual das mulheres brasileiras, portanto este estudo buscou traduzir o Questionnaire on Sexual Quality of Life – Female (SQoL-F) e apresentar evidências de validade do instrumento no contexto brasileiro. Métodos Foram realizados tradução, avaliação da validade de conteúdo, teste da versão pré-final e análise fatorial exploratória do instrumento. Resultados Identificou-se a presença de um único fator que explicou 49% da variância, condizente com o proposto no questionário original. Esse modelo unifatorial apresentou cargas fatoriais adequadas (entre 0,36 e 0,85). Conclusão O questionário apresentou boa consistência interna e foram apresentadas evidências de validade satisfatórias para o uso com mulheres brasileiras.

ABSTRACT Objective Posttraumatic stress disorder (PTSD) is a highly prevalent and disabling disorder. Even when treated with the first-line intervention, cognitive-behavioral therapy (CBT), 45% of the patients continue suffering from this disorder. Therefore, knowing the factors that could foresee who will respond to CBT would be of great value to the treatment of these patients. Thus, we have systematically reviewed the literature to identify the variables that could predict response to CBT in patients suffering from PTSD. Methods Following the PRISMA 2020 guidelines, we searched the electronic databases ISI Web of Science, Scopus, PsycINFO, MEDLINE, and PTSDpubs until November 2021. Two authors have independently conducted study selection and data extraction. Studies that examined possible predictors of response to therapy on a sample of adults (18-65 years), both genders, with and without comorbidities were considered eligible. The characteristics of the studies were synthesized in a table. The risk of bias was assessed by the Cochrane risk of bias quality assessment tool. Results Twenty-eight studies comprising 15 variables were selected. Among those, eight showed a low risk of bias, 19 showed some concerns, and one showed a high potential risk of bias. The therapeutic relationship was the only variable considered to be a predictor of a good response to therapy. All other variables showed conflicting results. Conclusions The most promising variable, although scientifically weak, is the therapeutic relationship. Additional randomized clinical trials should be conducted to clarify the role of this variable as a predictor of response to CBT in patients with PTSD.
