Fungal plastiphily and its link to generic virulence traits makes environmental microplastics a global health factor
Authors: Gkoutselis Gerasimos , Rohrbach Stephan , Harjes Janno , Brachmann Andreas , Horn Marcus , Rambold Gerhard
Published: March 2023

Fungi comprise significant human pathogens, causing over a billion infections each year. Plastic pollution alters niches of fungi by providing trillions of artificial microhabitats, mostly in the form of microplastics, where pathogens might accumulate, thrive, and evolve. However, interactions between fungi and microplastics in nature are largely unexplored. To address this knowledge gap, we investigated the assembly, architecture, and ecology of mycobiomes in soil (micro)plastispheres near human dwellings in a model- and network-based metagenome study combined with a global-scale meta-analysis. Our results reveal a strong selection of important human pathogens, in an idiosyncratic, otherwise predominantly neutrally assembled plastisphere, which is strongly linked to generic fungal virulence traits. These findings substantiate our niche expansion postulate, demonstrate the emergence of plastiphily among fungal pathogens and imply the existence of a ‘plastisphere virulence school’, underpinning the need to declare microplastics as a factor of global health.
A note on LASSI: a lightweight authenticated key agreement protocol for fog-enabled IoT deployment
Authors: Cao Zhengjun
Published: March 2023

We show that the scheme [Int. J. Inf. Sec., 21(6), 1373-1387] is flawed, in which the user encrypts the temporary ID using a symmetric key encryption in order to achieve the anonymity target. If the shared key for such a symmetric key encryption is really available, the scheme can be greatly simplified. We want to stress that the ultimate use of a key agreement scheme is just to establish a shared key for some symmetric key encryption, but not vise versa.

Every language has its own phonetic characteristics, including Arabic and Indonesian. However, interactions between communities can influence the development and change of language. This influence can be observed through vocabulary that is borrowed and modified from other languages, known as loanwords. In this study, the library research method was used to search and process information. The main sources used were the Arabic-Indonesian Dictionary by Mahmud Yunus and the Al-Munawwir Dictionary by Ahmad Warson Munawwir and Muhammad Fairuz. Meanwhile, secondary data was taken from the Indonesian Language Dictionary (KBBI). Based on the study, it is concluded that the borrowing of words from Arabic to Indonesian undergoes many modifications that are adjusted to the dialect of Indonesian speakers. The borrowing process starts from the spoken language, which is then transformed into the written language. Arabic loanwords in Indonesian have both positive and negative impacts on the learning process. The positive impact is that the presence of loanwords can help facilitate the learning process of other words. This impact can be felt if the sound and usage of the word remain unchanged. Negative impacts can occur if the sound and usage of the word undergo changes and modifications, making it difficult for students to understand the original sound and usage of the word in Arabic.

Speaking skills are one of the competencies taught in Arabic language learning. Students' mastery of Arabic is influenced by various factors during the learning process. Apart from internal factors, there are also external factors that play a significant role in achieving learning objectives. One of the external factors in Arabic language learning is the teaching methods employed in the classroom. The objective of this research is to examine the effectiveness of the ḥiwār method in enhancing the speaking skills of grade II students at Ulumul Qur'an College Takengon in Central Aceh. This study employed a quantitative research design utilizing quasi-experimental methods. The findings demonstrated that the t-value exceeds the t-critical value; 2.17 2.07. Therefore, the ḥiwār method is an effective approach to enhance the speaking skills of grade II students at Ulum al-Quran College Takengon. Future research may explore the effectiveness of other teaching methods in improving Arabic speaking skills among students.
Assessing water resources systems’ dynamic resilience under hazardous events via a genetic fuzzy rule-based system
Authors: Simic Visnja , Stojkovic Milan , Milivojevic Nikola , Bacanin Nikola
Published: March 2023

In this paper, the use of a novel genetic fuzzy rule-based system (FRBS) is proposed for assessing the resilience of a water resources system to hazards. The proposed software framework generates a set of highly interpretable rules that transparently represent the causal relationships of hazardous events, their timings, and intensities that can lead to the system's failure. This is achieved automatically through an evolutionary learning procedure that is applied to the data acquired from system dynamics (SD) and hazard simulations. The proposed framework for generating an explainable predictive model of water resources system resilience is applied to the Pirot water resources system in the Republic of Serbia. The results indicate that our approach extracted high-level knowledge from the large datasets derived from multi-model simulations. The rule-based knowledge structure facilitates its common-sense interpretation. The presented approach is suitable for identifying scenario components that lead to increased system vulnerability, which are very hard to detect from massive raw data. The fuzzy model also proves to be a satisfying fuzzy classifier, exhibiting precisions of 0.97 and 0.96 in the prediction of low resilience and high rapidity, respectively.
Variability of urban drainage area delineation and runoff calculation with topographic resolution and rainfall volume

Published: March 2023

Designing green stormwater infrastructure (GSI) requires an accurate estimate of the contributing drainage area and a model for runoff generation. We examined some factors that add to the uncertainty associated with these two design steps in the urban environment. Delineated drainage areas at five GSI sites in southeastern Pennsylvania (PA) were compared for digital elevation model (DEM) resolutions (grid cell sizes) ranging from 8 to 300 cm. The findings point to an optimal DEM resolution range of 30–60 cm, with up to 100 cm resolution providing acceptable results for some sites. The delineated areas were validated with the observed flow and rainfall records at three sites by examining curve number (CN) values calculated for individual storms. The calculated CNs decreased with increasing rainfall volume, which supports a recommendation to consider a range of CNs in the GSI design process. The variation in calculated CNs was higher for the overestimated drainage areas derived from coarser DEM resolutions. We hypothesize that the observed continued decrease of CNs at high rainfall is the result of inlet bypass, a potentially significant factor in urban hydrology. The findings from this study provide insight into the variability in expected delineated drainage areas using standard methods in GSI design.

Published: March 2023

Estimation of elements: Pb, Zn, Mn, Cd, and Cu, which were conducted seasonally from October-2021 till March-2022 in residential areas of Baghdad City using Geoaccumulation index (Igeo), enrichment factor ratios (EF), the factor of contamination (CF), contamination degree (Cd), index of pollution load (PLI) and index of potential ecological risk (Eif). The overall contamination factor in the research area is limited from low contamination with Cu, Mn, and Zn, moderately contaminated to very high contamination with Pb and Cd, while the assessment according to the I-geo index shows categories that vary from a slightly polluted to unpolluted by those examined heavy metals. The pollution load index indicates that the soils in some residential areas in Baghdad City have high levels of contamination by certain heavy metals. According to the EF results, the areas were moderately to significantly enriched with Pb and Cd and minimally enriched with Mn, Zn, and Cu. The potential for ecological risk had an irregular distribution, and the overall ecological risk level ranged from moderate to low. The PLI depicts the research area's vulnerability to soil heavy metal contamination and associated ecological concerns, particularly from lead and cadmium.

A model for the SARS-CoV-2 dynamics in a population lacking herd immunity
Authors: Medina-Vásquez Paúl , Romero-Romero Ray , Mayorga-Zambrano Juan
Published: March 2023

We introduced the S-HI model, a generalized SEIR model to describe the dynamics of the SARS-CoV-2 virus in a community without herd immunity and performed simulations for six months. The S- HI model consists of eight equations corresponding to susceptible individuals, exposed, asymptomatic infected, asymptomatic recovered, symptomatic infected, quarantined, symptomatic recovered and dead. We study the dynamics of the infected, asymptomatic. Dead classes in 4 different networks: households, workplaces, agglomeration places and the general community, showing that the dynamics of the three compartments have the exact nature in each layer and that the speed of the disease considerably increases in the networks with the highest weight of contacts. The reproduction number, R0, is greater than 1 in all networks conforming to the theory. The variants of the SARS-Cov-2 virus are not taken into account, so the S-HI model would fit a situation similar to the first wave of contagion after the mandatory lockdown.

Keywords: SARS-Cov-2, mathematical models, SEIR, data-driven networks, simulations, basic reproduction number, lack of herd immunity.

Published: March 2023

A total of 9 samples of wild cat Felischausfurax (de Winton, 1898) and 13 (11 positives) samples of domestic cat Feliscattus (Linnaeus, 1758) belong to Family Felidae. All cats were trapped and used hair and skin scrapings by forceps and surgical blades. The areas of the collection were: Mosul province (north of Iraq); Baghdad, Al-Rashidiya, Tharthar, Nahrawan, AL-Mahmoudiya (middle of Iraq) and AL-Haretha (south of Iraq). The current study revealed that the sensitive and specific PCR assay allowing rapid and reliable identification of Malasseziarestricta by the fragment size amplified was 500bp in the ITS1 gene in one sample of wild cats. The current study recorded a new strain of Malasseziarestrictathat called AF2013 strain "small subunit ribosomal RNA gene, partial sequence; internal transcribed spacer 1", complete sequence; and 5.8S ribosomal RNA gene, partial sequence. Which was inserted in GenBank: MW376484.1 from wild cat Felischausfurax for the first time in Iraq. Sequencing revealed close matching of the phylogenetic tree to an isolate from Korea (CP030254). The compression was performed using NCBI – the based nucleotides website.

El Hospital Pablo Arturo Suárez, ubicado en Quito, la capital de Ecuador, se convirtió en un hospital de atención exclusiva para pacientes COVID-19 desde marzo de 2020, y fue uno de los primeros centros en inmunizar a su personal con un solo tipo de vacuna, la de Pfizer-BioNTech.

Se realizó un estudio de farmacovigilancia en 1304 trabajadores sanitarios de este centro que fueron inmunizados entre enero y marzo del 2021. Los vacunados tuvieron una media de edad de 38,7 años y predominó el sexo femenino (63%). Reportaron efectos adversos 81 (6%) inmunizados, su media de edad fue de 38,8 años y predominaron las mujeres (69%), similar a la población total. Se reportaron 305 efectos adversos relacionados a las vacunas, de ellos, solo 1 (0,3%) fue grave y requirió hospitalización, el resto (23%) fueron no graves. La cefalea, el malestar general, el dolor en el sitio de inyección fueron los efectos más reportados.

Los resultados obtenidos muestran un paralelismo de lo reportado a nivel mundial sobre la seguridad de las vacunas contra el COVID-19 en general y la Pfizer-BioNTech en particular. La relevancia de nuestro trabajo radica en que es uno de los primeros reportes de reactogenicidad de esta vacuna en una ciudad de altitud a inicios de la pandemia, en una corte de personal sanitario directamente dedicado a la atención de este tipo de pacientes.

Polycyclic aromatic hydrocarbons mainly originate from the incomplete combustion of fossil fuels such as petroleum, natural gas and coal. Also, biomass burning has attracted much attention due to its mutagenic, allergenic and carcinogenic properties. Anthracene, a three-ringed polycyclic aromatic hydrocarbon, is widely known as a common hazardous ubiquitous environmental pollutant. Anthracene is used to make dyes, plastics and pesticides.
The present study aims to evaluate the risks of Anthracene to fish using a micronucleus (MN) assay; the test has been used successfully as a mutagenic assay. Ninety fishes were adapted and acclimated to the laboratory conditions for one week before starting the experiment, then were exposed to (7.5mg/L, 10mg/L, and 12.5mg/L) of Anthracene for 72 hours. Results demonstrated that the LD50 of Anthracene in fish was (10 mg/L). Based on the values of LC50, the fish were then exposed for 72 h to three concentrations of sub-lethal Anthracene (2.5 mg/L, 5 mg/L and 7.5 mg/L) and control (0.00 mg/L) after (72 hours, 10 days, 20 days). Peripheral blood samples smears were collected from each group, the sample was stained by Giemsa stain, and frequencies of MNs were counted. The study showed an increase in micronuclei with concentration and period. In conclusion, it can use of the micronucleus assay in erythrocytes of fish as a sensible index for the assessment and evaluation of aquatic environmental pollution

Evaluating Web-Based Care for Mental Health and Substance Use Issues for Lesbian, Gay, Bisexual, Transgender, Queer, Questioning, and 2-Spirit Youths in the Context of the COVID-19 Pandemic: Community-Based Participatory Research Study
Authors: Chaiton Michael , Thorburn Rachel , Chan Emily , Copeland Ilana , Luphuyong Chieng , Feng Patrick
Published: March 2023

Background

Mental health (MH) and substance use (SU) care supports are often difficult to access for the lesbian, gay, bisexual, transgender, queer, questioning, and 2-spirit (LGBTQ2S+) population. There is little known on how the shift to web-based care has affected and changed the experiences of LGBTQ2S+ youths within the MH care system.

Objective

This study sought to examine how web-based care modalities have affected access to care and quality of care for LGBTQ2S+ youths seeking MH and SU services.

Methods

Researchers used a web-based co-design method to explore this population’s relationship with MH and SU care supports, focusing on the experiences of 33 LGBTQ2S+ youths and their relationship with MH and SU supports during the COVID-19 pandemic. A participatory design research method was used to gain experiential knowledge of LGBTQ2S+ youths’ lived experience with accessing MH and SU care. Thematic analysis was used to examine the resulting audio-recorded data transcripts and create themes.

Results

Themes related to web-based care included accessibility, web-based communication, provision of choice, and provider relationship and interactions. Barriers to care were identified in particular for disabled youths, rural youths, and other participants with marginalized intersecting identities. Unexpected benefits of web-based care were also found and emphasize the idea that this modality is beneficial for some LGBTQ2S+ youths.

Conclusions

During the COVID-19 pandemic, a time where MH- and SU-related problems have increased, programs need to reevaluate current measures so that the negative effects of web-based care modalities can be reduced for this population. Implications for practice encourage service providers to be more empathetic and transparent when providing services for LGBTQ2S+ youths. It is suggested that LGBTQ2S+ care should be provided by LGBTQ2S+ folks or organizations or service providers who are trained by LGBTQ2S+ community members. Additionally, hybrid models of care should be established in the future so that LGBTQ2S+ youths have the option to access in-person services, web-based ones, or both as there can be benefits to web-based care once it has been properly developed. Implications for policy also include moving away from a traditional health care team model and developing free and lower-cost services in remote areas.

UNSTRUCTURED

International deployment of remote monitoring and virtual care (RMVC) technologies would efficiently harness their positive impact on outcomes. Since Canada and the United Kingdom have similar populations, health care systems, and digital health landscapes, transferring digital health innovations between them should be relatively straightforward. Yet examples of successful attempts are scarce. In a workshop, we identified 6 differences that may complicate RMVC transfer between Canada and the United Kingdom and provided recommendations for addressing them. These key differences include (1) minority groups, (2) physical geography, (3) clinical pathways, (4) value propositions, (5) governmental priorities and support for digital innovation, and (6) regulatory pathways. We detail 4 broad recommendations to plan for sustainability, including the need to formally consider how highlighted country-specific recommendations may impact RMVC and contingency planning to overcome challenges; the need to map which pathways are available as an innovator to support cross-country transfer; the need to report on and apply learnings from regulatory barriers and facilitators so that everyone may benefit; and the need to explore existing guidance to successfully transfer digital health solutions while developing further guidance (eg, extending the nonadoption, abandonment, scale-up, spread, sustainability framework for cross-country transfer). Finally, we present an ecosystem readiness checklist. Considering these recommendations will contribute to successful international deployment and an increased positive impact of RMVC technologies. Future directions should consider characterizing additional complexities associated with global transfer.

Being the most populous country and the second biggest economy in the world, the PRC (Peoples Republic of China) is one of the most consequential State Actors in the contemporary international order/system by any yardstick. Like other great powers she follows a strategic vision or grand strategy to accomplish her aims. Meanwhile, importance of SCO (Shanghai Cooperation Organisation) can be gauged from the fact that this relatively new international body, set up in 2001, accounts for 60% of the land mass and 45% proven energy reserves in the world. In this essay I would like to analyse how SCO fits into the Beijing's foreign policy framework and Grand Strategy and whether the different aims and goals of the SCO are aligned with PRC’s interests and objectives.
Correlation between Distribution of Water Fluoride and Fluorosis in the villages of Mahendergarh district, Haryana- India
Authors: Yadav Sucheta
Published: March 2023

Fluoride plays a very important role in preventing dental carries and is beneficial for dental enamel. But fluoride is valuable for health only when if it is used in a small amount within the allowable limit. Its excessiveness causes a number of side effects for human health such as fluorosis. According to WHO recommendation in 2011, fluoride level in drinking water is 1.5 mg/l. In everyday life, drinking water is considered as major source of fluoride. Most of the residents of Mahendergarh district of Haryana in India depend on ground water for their drinking purposes. This study has been conducted to examine the dental fluorosis among govt. school children in the villages of the study area. The fluorosis data were collected from different blocks of Mahendergarh district from school going children aged between 6 to 11 years old. A face-to-face interview of school children from class-3rd to class-5th has been carried out. A total of 43 villages were selected for dental fluorosis analysis. 25 villages were selected where the fluoride level is more than 1.5 mg/l and 18 villages were chosen where fluoride level was less than 1.5 mg/l. A survey was carried out among 1196 school going children for oral examination of dental fluorosis. School children were examined with the help of an expert of dental fluorosis. The study revealed that children of Sihma, Mahendergarh, Narnaul and Nangal Chaudhary blocks are the most affected with dental fluorosis. It was found that 33.3% children were affected with dental fluorosis in high fluoride zone, while only 7.36% children were suffering from dental fluorosis below permissible area (below 1.5mg/l). The study also reveals the positive correlation between water fluoride and fluorosis.

Published: March 2023

Abstract: In India, the annual production of GGBS is 15 million tons and only 55% of GGBS is used in the construction industry. It is therefore important to increase the use of industrial waste on a larger scale for environmental benefits in the concrete industry. Numerous studies have been performed on these SCMs to evaluate the properties of his GGBS-containing concrete in fresh and cured states. Using by-products of the slag industry to higher replacement levels for cement could significantly reduce the price of concrete. Paving economical and environmentally friendly concrete Green house gas (GHG) emissions are effectively reduced by 47.5% by using GGBS as a cement substitute. India is the largest producer of fly ash. In one year he produces more than 112 million tons of fly ash. 60-70% of the fly ash is consumed and the rest is spread over the ground. This is because the government encourages the use of his 100% fly ash to avoid landfills and create a greener environment.

Published: March 2023

The microbiome is a population of microbes that colonized in mammalian gut. During the first few years of life, the gut microbiome undergoes alteration and is very diverse in adulthood, depends upon various of circumstances. Gut microbes, particularly gut flora in ruminants, are receiving more and more attention. Intestinal microbes, particularly ruminant microorganisms, have attracted an increasing amount of attention as high-throughput sequencing technology has improved and costs have decreased, whether in the fundamental research or application fields. The ruminant microbiome changes in conjunction with its host and it is influenced by inter-microbial interactions, environmental exposures, and host properties. However, any organism's core functional microbiome is much more conventional. Unfortunately, the fragile growth ratio of the microbial culture is susceptible to incursions under illness circumstances, which may affect the abundance of various microbial species, resulting to dysbiosis. As a result, the purpose of this review is to provide a broad summary of the relevance of ruminant gut microorganisms, as well as to investigate variables that influence the microbiota and alternative therapeutics such as probiotics, prebiotics, fecal transplantation, and rumen transfiguration, all of which have been shown to be effective in addressing dysbiosis.

Objectives: The study aim is to assess the vaccination status of children under two years old in Al-Asatetha primary health care center / Hilla-Iraq.

Method: Retrospective study design (Retrospective chart review) was used to assess the missed opportunities of vaccination for children under the age of two years by reviewing their immunization status from medical reports at the primary health care center. The purposive sampling was used to collect the data of 1000 children born from 1-1-2020 to 31-12-2020 through the period from 1 December 2021 to 1 February 2022.

Results: the finding of the current study showed that the age of children in the selected period (2020-2021) was between11-23 months, the number of children (1-8) in the same family, and almost all of these families reside in urban areas. Regarding the parents’ educational level the high percentage of both fathers and mothers were attained a primary level of education, and most of the fathers were working, while most of the mothers were not work. Concerning the vaccination status the finding showed that the percentage of missed vaccination opportunities reached 61%, and there was a significant positive correlation between vaccination status and (family residence, parental education level, and fathers' occupation) with a P value of 0.01. On the other hand, the number and the order of children in families had an inversely significant relationship with vaccination status at a P value of 0.01.

Conclusion: the study concludes that numerous factors affect the vaccination rate such as parents' education attainment and awareness, family size, address, and economic status of the family.

Purpose: Mental health problems affect an estimated 700 million
people worldwide, and the prescription of psychotropic drugs is
increasing globally. The World Health Organization has called for
adequate surveillance of psychotropic drug prescriptions. This study
aims to characterize and find trends in the prescription of
psychotropics in a Latin American Hospital. Methods: The study
analyzed the dispensation of psychotropic prescriptions to outpatients
at three pharmacies in the central headquarters of Hospital Clínica
Bíblica in San José, Costa Rica, from 2017 to 2021. Psychotropic drugs
were classified by ATC groups, and the amount of each medication
dispensed was standardized using the defined daily dose per 10000
population per day metric. The prescriptions were categorized according
to medical specialty. Results: A total of 5793 psychotropic
prescriptions were recorded. The average age of the patients was 58
years. The total consumption of psychotropics decreased by 33.94% from
2017 to 2021, with the most significant decline until 2020. However,
there was an increase in consumption in 2021. The most commonly used
drugs were clonazepam, bromazepam, and alprazolam. Alprazolam was the
only drug that showed an increase in consumption. Anxiolytics were the
most commonly prescribed group of drugs. General medicine and psychiatry
were the primary specialties that prescribed psychotropics.
Conclusion: the consumption of psychotropic drugs decreased
from 2017 to 2020 but increased in 2021, with alprazolam being the only
drug that showed an increase in consumption throughout the entire
period. The elderly population was found to be the group that consumed
the most psychotropics.

Aim: The purpose of this study was to optimize the dosing schedule of
recombinant human erythropoietin (rhEPO) for perioperative autologous
blood donation in patients undergoing total knee arthroplasty (TKA).
Method: TKA patients receiving different dosing schedules of rhEPO were
randomly divided into three groups. Group A patients were given 10,000
IU of subcutaneous rhEPO (1 ml) daily from preoperative day 5 to
postoperative day 3 (9 doses); Group B patients were given subcutaneous
normal saline daily from preoperative day 5 to day 3 and then
subcutaneous rhEPO daily until postoperative day 3 (6 doses in total);
Group C patients were given subcutaneous normal saline daily from
preoperative day 5 to the day before surgery and then subcutaneous rhEPO
daily from the surgery day to postoperative day 3 (4 doses). Results: A
total of 180 TKA patients were included. On postoperative day 1 and 3,
group A showed significantly higher Hb levels than group B and group C.
The calculated blood loss was significantly greater in groups B and C
than in group A on the day after surgery. Regarding total blood loss,
groups B and C lost significantly more blood than group A. No case of
allogeneic transfusion occurred during the trial in any of the three
groups. Conclusions: A small dose of daily rhEPO from preoperative day 5
to postoperative day 3 could significantly increase perioperative
autologous blood donation efficacy and slow the decline in postoperative
Hb levels in TKA patients without causing extra complications.
Impulsive fractional partial differential system and its correct integral solution

It is found that there are two piecewise functions satisfy the
conditions in the impulsive fractional partial differential system
(IFrPDS), which deduce that the three different integral solutions of
the IFrPDS given in the cited papers are inappropriate. Next, by
applying two limit properties of the IFrPDS and the properties of
piecewise function, the new formula of solution of the IFrPDS is
discovered that is the integral equation with an arbitrary continuously
differentiable function of t on [0 ,c] to reveal the
non-uniqueness of the IFrPDE’s solution. Finally, an example is provided
to expound the computation of the solution of the IFrPDS.

Background: Reproductive risk factors are associated with
increased risk of cardiovascular disease (CVD) in women. However, the
combined effects of the composite reproductive risk factors on CVD are
unknown. This study was performed to construct a reproductive risk score
(RRS) to measure reproductive status, examine the association between
RRS and CVD, and explore the modification effect of healthy lifestyle on
the association in women in the UK Biobank cohort. Methods: The
RRS was constructed in 74 141 female participants with data about the
items derived for the RRS in the UK Biobank. The RRS was derived from 17
baseline variables, all of which indicated women’s reproductive health
status. We defined four categories of RRS status: low-risk group (score
0–1); low-intermediate group (score 2–3); high-intermediate group
(score 4–5); and high-risk group (score 6–13). We also constructed a
healthy lifestyle score (HLS) with five related factors, and categorized
into unhealthy lifestyle group (score: 0–1), intermediate lifestyle
group (score: 2–3) and healthy lifestyle group (score: 4–5).
Findings: Each point increase in the RRS was associated with a
22% higher risk of CVD (adjusted hazard ratio (aHR): 1.22; 95%
confidence interval (CI): 1.16 to 1.28), 23% higher risk of IHD (1.23;
1.17 to 1.31) and 19% higher risk of stroke (1.19; 1.07 to 1.32). The
percentage population-attribution risks (PAR%) were 16% (95% CI: 8 to
24) for CVD, 15% (95% CI: 6 to 24) for IHD and 18% (95% CI: 1 to 33)
for stroke. A healthy lifestyle significantly attenuated RRS
associations with the incidence of CVD and IHD. The attributable
proportions due to additive interaction ( P < 0.001)
between RRS and HLS were 0.14 (95% CI: 0.07 to 0.22) for CVD and 0.15
(95% CI: 0.09 to 0.23) for IHD, respectively. Interpretation:
High RRS was associated with increased risks of CVD, IHD and stroke in
female participants in the UK Biobank. The early-stage identification of
women with reproductive risk using synthesised indicators and
appropriate healthy lifestyle interventions could be useful for the
prevention of early CVD and the extension of healthy active life
expectancy. Funding: This study was supported by grants from
