ABSTRACT

BACKGROUND: Maternal health outcomes have been underresearched due to people who are pregnant being underrepresented or excluded from studies based on their status as a vulnerable study population. Based on the available evidence, Black people who are pregnant have dramatically higher maternal morbidity and mortality rates compared to other racial and ethnic groups. However, insights into prenatal care-including the use of medications, immunizations, and prenatal vitamins-are not well understood for pregnant populations, particularly those that are underrepresented in biomedical research. Medication use has been particularly understudied in people who are pregnant; even though it has been shown that up to 95% of people who are pregnant take at least 1 or more medications. Understanding gaps in use could help identify ways to reduce maternal disparities and optimize maternal health outcomes.

OBJECTIVE: We aimed to characterize and compare the use of prenatal vitamins, immunizations, and commonly used over-the-counter and prescription medications among people who are pregnant, those self-identifying as Black versus non-Black, and those living in rural versus urban regions in the United States.

METHODS: We conducted a prospective, decentralized study of 4130 pregnant study participants who answered survey questionnaires using a mobile research app that was only available on iOS (Apple Inc) devices. All people who were pregnant, living in the United States, and comfortable with reading and writing in English were eligible. The study was conducted in a decentralized fashion with the use of a research app to facilitate enrollment using an eConsent and self-reported data collection.

RESULTS: Within the study population, the use of prenatal vitamins, antiemetics, antidepressants, and pain medication varied significantly among different subpopulations underrepresented in biomedical research. Black participants reported significantly lower frequencies of prenatal vitamin use compared to non-Black participants (P<.001). The frequency of participants who were currently receiving treatment for anxiety and depression was also lower among Black and rural groups compared to their non-Black and urban counterparts, respectively. There was significantly lower use of antidepressants (P=.002) and antiemetics (P=.02) among Black compared to non-Black participants. While prenatal vitamin use was lower among participants in rural areas, the difference between rural and urban groups did not reach statistical significance (P=.08). There were no significant differences in vaccine uptake for influenza or tetanus-diphtheria-pertussis (TDaP) across race, ethnicity, rural, or urban status.

CONCLUSIONS: A prospective, decentralized app-based study demonstrated significantly lower use of prenatal vitamins, antiemetics, and antidepressants among Black pregnant participants. Additionally, significantly fewer Black and rural participants reported receiving treatment for anxiety and depression during pregnancy. Future research dedicated to identifying the root mechanisms of these differences can help improve maternal health outcomes, specifically for diverse communities.

ABSTRACT

BACKGROUND: Health technology innovation is increasingly supported by a bottom-up approach to priority setting, aiming to better reflect the concerns of its intended beneficiaries. Web-based forums provide parents with an outlet to share concerns, advice, and information related to parenting and the health and well-being of their children. They provide a rich source of data on parenting concerns and priorities that could inform future child health research and innovation.

OBJECTIVE: The aim of the study is to identify common concerns expressed on 2 major web-based forums and cluster these to identify potential family health concern topics as indicative priority areas for future research and innovation.

METHODS: We text-mined the r/Parenting subreddit (69,846 posts) and the parenting section of Mumsnet (99,848 posts) to create a large corpus of posts. A generative statistical model (latent Dirichlet allocation) was used to identify the most discussed topics in the corpus, and content analysis was applied to identify the parenting concerns found in a subset of posts.

RESULTS: A model with 25 topics produced the highest coherence and a wide range of meaningful parenting concern topics. The most frequently expressed parenting concerns are related to their child’s sleep, self-care, eating (and food), behavior, childcare context, and the parental context including parental conflict. Topics directly associated with infants, such as potty training and bottle feeding, were more common on Mumsnet, while parental context and screen time were more common on r/Parenting.

CONCLUSIONS: Latent Dirichlet allocation topic modeling can be applied to gain a rapid, yet meaningful overview of parent concerns expressed on a large and diverse set of social media posts and used to complement traditional insight gathering methods. Parents framed their concerns in terms of children’s everyday health concerns, generating topics that overlap significantly with established family health concern topics. We provide evidence of the range of family health concerns found at these sources and hope this can be used to generate material for use alongside traditional insight gathering methods.

ABSTRACT

BACKGROUND: The medical teams in intensive care units (ICUs) spend increasing amounts of time at computer systems for data processing, input, and interpretation purposes. As each patient creates about 1000 data points per hour, the available information is abundant, making the interpretation difficult and time-consuming. This data flood leads to a decrease in time for evidence-based, patient-centered care. Information systems, such as patient data management systems (PDMSs), are increasingly used at ICUs. However, they often create new challenges arising from the increasing documentation burden.

OBJECTIVE: New concepts, such as artificial intelligence (AI)-based assistant systems, are hence introduced to the workflow to cope with these challenges. However, there is a lack of standardized, published metrics in order to compare the various data input and management systems in the ICU setting. The objective of this study is to compare established documentation and retrieval processes with newer methods, such as PDMSs and voice information and documentation systems (VIDSs).

METHODS: In this crossover study, we compare traditional, paper-based documentation systems with PDMSs and newer AI-based VIDSs in terms of performance (required time), accuracy, mental workload, and user experience in an intensive care setting. Performance is assessed on a set of 6 standardized, typical ICU tasks, ranging from documentation to medical interpretation.

RESULTS: A total of 60 ICU-experienced medical professionals participated in the study. The VIDS showed a statistically significant advantage compared to the other 2 systems. The tasks were completed significantly faster with the VIDS than with the PDMS (1-tailed t₅₉=12.48; Cohen d=1.61; P<.001) or paper documentation (t₅₉=20.41; Cohen d=2.63; P<.001). Significantly fewer errors were made with VIDS than with the PDMS (t₅₉=3.45; Cohen d=0.45; P=.03) and paper-based documentation (t₅₉=11.2; Cohen d=1.45; P<.001). The analysis of the mental workload of VIDS and PDMS showed no statistically significant difference (P=.06). However, the analysis of subjective user perception showed a statistically significant perceived benefit of the VIDS compared to the PDMS (P<.001) and paper documentation (P<.001).

CONCLUSIONS: The results of this study show that the VIDS reduced error rate, documentation time, and mental workload regarding the set of 6 standardized typical ICU tasks. In conclusion, this indicates that AI-based systems such as the VIDS tested in this study have the potential to reduce this workload and improve evidence-based and safe patient care.

ABSTRACT

The paucity of education and training on alcohol use disorders (AUDs) in nursing curricula is the main predictor of negative attitudes and results in limited knowledge access and delivery of health care for persons experiencing these problems. Although experts advocate increasing the time devoted to alcohol-related content in a crowded curriculum, didactic strategies for teaching about addiction in prequalifying nursing education have been discussed. This study aimed to verify the effectiveness of an educational experience that integrated clinical practicum experience in addiction treatment facilities for nursing students’ attitudes. A quasi-experimental one-group study with pre-and-post 3-month follow-ups was carried out with 108 nursing students who answered the Attitudes Scale toward Alcohol, Alcohol Use Disorder, and Patients with Alcohol Use Disorders. The effect of the clinical practicum was apparent, with statistically significant changes to more positive global attitude scores in all measures. Previous educational intervention for AUDs during nursing education was a predictor of positive attitudes (OR = 7.21, p < .04). Students’ self-perceived skills and professional preparation to deliver and direct care for patients with AUDs improved after the intervention, suggesting that clinical practice influenced students’ skills for AUD identification across nursing practice. Previous contact with this population with lack of training in substance use disorder seems to favor negative attitude development. Clinical practicum experience in addiction treatment facilities improved nursing students’ attitudes toward AUDs and patients with AUDs, and its effects were sustained 3 months later.

ABSTRACT

Patients with substance use disorder (SUD) encounter many barriers to healthcare, including negative attitudes of healthcare personnel. Compared with other healthcare professions, nurses have been reported as having less tolerant attitudes toward patients with SUD. Knowledge acquisition combined with role support has been shown to improve therapeutic attitudes of nurses toward patients with SUD. Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based educational intervention aimed to improve the outcomes of patients at risk and with SUD. SBIRT education has been shown as an effective educational tool with licensed nurses. Therefore, the aim of this study was to evaluate whether a 2-hour educational session on SBIRT (Mitchell et al., 2013) improved the therapeutic attitudes of nurses toward patients with SUD. Peplau’s theory of interpersonal relations guided this study with an emphasis on the nurse-patient relationship. A quasi-experimental pretest/posttest design was used to evaluate nurses’ attitudes pre and post a 2-hour educational session. Participants included 65 registered nurses employed in a 247-bed teaching hospital in New England. Attitudes were measured before and after the educational session using the 20-item, five-subscale Drug and Drug Problems Perceptions Questionnaire. A paired t test was performed, showing statistically significant improvements in attitudes postintervention. Prior education on SUD significantly correlated with baseline attitudes. A standard regression model, with practice setting, family history of SUD, and prior education as dependent variables, was not predictive of baseline attitudes. The results suggest conducting SBIRT should be considered a mandatory nursing competency, both in undergraduate curriculum and among licensed nurses.

ABSTRACT

INTRODUCTION: Chronic venous disease (CVD) can lead to considerable morbidity and impact health-related quality of life (HRQoL). The aim of this review was twofold: (i) to provide a deeper understanding of how CVD affects HRQoL (physical, psychological and social functioning), and (ii) to review the impact of evidence-based veno-active drugs (VADs) on HRQoL.

EVIDENCE ACQUISITION: For the effect of CVD on HRQoL, information was gathered during an Expert Consensus Meeting, during which data were presented from both the patient and physician perspective assessed with validated quality-of-life measures. For the impact of VADs on HRQoL, a systematic literature review was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic databases were searched for real world evidence or randomized-controlled trials (RCT) vs. placebo, reporting data on the influence of VADs on HRQoL in patients with CVD.

EVIDENCE SYNTHESIS: CVD can negatively affect daily life in a number of areas related to pain, physical function and social activities. The impact of CVD on HRQoL begins early in the disease and for patients the emotional burden of the disease is as high as the physical burden. In contrast, physicians tend to overestimate the physical impact. The database search yielded 184 unique records, of which 19 studies reporting on VADs and HRQoL in patients with CVD met the inclusion criteria (13 observational and 6 RCTs). Micronized purified flavonoid fraction (MPFF) was the most represented agent, associated with 12/19 studies (2 RCTs and 10 observational). Three of the 6 RCTs provided statistically significant evidence for improvement on HRQoL compared with placebo: two for MPFF (24.4% and 19.2% improvement in HRQoL vs. placebo, respectively) and one for a low-dose diosmin (20% improvement vs. placebo); for the other VADs improvements in HRQoL were not statistically different from placebo. MPFF was also associated with improvements in HRQoL in the observational studies, across all CEAP clinical classes, as monotherapy or in combination with other conservative therapy, and for all aspects of HRQoL: physical, psychological, and social. Real-world data for the other VADs were scarce. Ruscus extract, sulodexide and a semi-synthetic diosmin were each represented by a single observational study and these limited data were associated with statistically significant improvements compared with baseline in overall and subdomain scores across the range of CEAP clinical classes.

CONCLUSIONS: CVD can impair patients’ HRQoL significantly at all stages of the disease. MPFF has the greatest evidence base of clinical use in both RCT and real-world observational studies for effectiveness on HRQoL and is recognized by international guidelines.

ABSTRACT

Colorectal cancer (CRC) is the third leading cause of cancer-related deaths worldwide. The tumor suppressor gene MT-CO1, and Kristen Rat Sarcoma Virus (KRAS), an oncogene are primarily responsible for controlling cell apoptosis, cell cycle arrest, and cell proliferation, and any irregularities in these genes could lead to cancer. This study aims to examine the expression of KRAS and MT-CO1 in CRC biopsy specimens and investigate their relationship with one another in CRC patients residing in the Erbil city of Kurdistan Region, Iraq. The study involved categorizing 42 sets of colorectal cancer tissues and their corresponding controls based on their types and patients’ clinical characteristics. The expression of KRAS and MT-CO1 in the samples was assessed using Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR), with statistical significance set at p<0.05. The expression of KRAS was found to be significantly higher in CRC compared to the control (n=42, p=0.0001). On the other hand, the expression of MT-CO1 did not exhibit significant differences compared to the control group with a p-value of 0.12. Furthermore, the Chi-square and correlation analysis results depicted that MT-CO1 expression negatively correlates with KRAS expression (p= 0.0001, r= -0.047) in CRC tissues. In conclusion, the variation in the expression of KRAS and MT-CO1, and their correlations could potentially serve as a good indicator in the detection and prognosis of CRC, which might lead to better translational research on the same. However, for a better understanding of the underlying mechanisms, further analysis is required.

ABSTRACT

This study aims to investigate the Interleukin (IL)-6 rs1800795 and peroxisome proliferator-activated receptor alpha (PPARA) rs4253778 polymorphism distributions in the relatively faster and slower subgroups of national cross-country skiing athletes and to identify advantageous genotypes for endurance performance. IL-6 is an inflammatory mediator that is effective in muscle tissue hypertrophy, repair, and the immune system. On the other hand, PPARA transcription factor is a molecule associated with fatty acid, sugar metabolism and inflammation formation. Total of 30 professional cross-country skiing athletes were examined in three groups as athletes, female athletes, and male athletes. DNA of the participants were isolated from blood and genetic polymorphisms were determined by RT-PCR. Athletes were divided into two subgroups as faster and slower referring to their “1-kilometer cross-country skiing time averages (CCSTA)”. Polymorphism distributions in these subgroups were analyzed statistically with Fisher’s exact test and descriptive tests. In addition, the 1 km-CCSTA values of the genotypes were determined by descriptive statistical methods and the time advantages were calculated. It was determined that the combination of IL-6 rs1800795 GC and PPARA rs4253778 GG genotypes was observed to be more prominent among the faster categories of cross-country skiing competitors, particularly in the athletes and male athletes categories, and it had a time advantage at 1 km-CCSTA. The GC genotype (p= 0.0098) and C-allele (p=0.0398) of IL-6 rs1800795 polymorphism were detected at a higher rate in the fast subgroup in male athletes. These genotypes may support endurance performance.

ABSTRACT

We aimed to analyze the effect of acute exercise on oral microbiota in regularly trained swimmers. As environmental factors may affect the oral microbiota; we also aimed to analyze the short-duration effect of swimming training on the oral bacteria relative difference in swimmers. Saliva samples of 20 swimmers both before and after the training were used for the oral microbiota metagenesis. The next-generation sequencing method targeting 16S rDNA gene fragments was used for genotyping. The Wilcoxon signed-rank test was used for the statistical evaluation of the taxons. The alfa diversity comparisons were assessed with the One-Way ANOVA, and the Kruskal-Wallis test was used to determine bacterial diversity. Decayed- Missed- Filled total (DMF-T) scores were the indicators of oral hygiene. A comparison of the before and after exercise microbiota of the swimmers gave rise to a statistically significant difference for Firmicutes (p=0.014) and Bacteroidetes (p=0.007) phylum; Clostridia (p=0.006) and Bacilli (p=0.048) classes; Clostridiales (p=0.004), Entomoplasmatales (p=0.009) and Bacillales (p=0.006) for ordo; Lachnospiraceae (p=0.001) family and Stenotrophomonas (p=0.013) genus. Although there were some differences within the other taxa of the bacteria, all were statistically insignificant. Streptococcus, Pseudomonas and Rothia mucilaginosa showed a correlation with the DMF-T values in swimmers. This study was the first in Turkish swimmers to investigate the relative abundance of oral microbiota. We showed that exercise within the pool water changed the oral bacteria’s relative abundance. To confirm our results and clarify the effect of pool water on oral bacteria relative abundance, more studies on dietary intake should be carried out.

ABSTRACT

IMPORTANCE: There is limited evidence of the association of conditional cash transfers, an important strategy to reduce poverty, with prevention of adverse birth-related outcomes.

OBJECTIVE: To investigate the association between receiving benefits from the Bolsa Família Program (BFP) and birth weight indicators.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study used a linked data resource, the Centro de Integracao de Dados e Conhecimentos Para Saude (CIDACS) birth cohort. All live-born singleton infants born to mothers registered in the cohort between January 2012 and December 2015 were included. Each analysis was conducted for the overall population and separately by level of education, self-reported maternal race, and number of prenatal appointments. Data were analyzed from January 3 to April 24, 2023.

EXPOSURE: Live births of mothers who had received BFP until delivery (for a minimum of 9 months) were classified as exposed and compared with live births from mothers who did not receive the benefit prior to delivery.

MAIN OUTCOMES AND MEASURES: Low birth weight (LBW), birth weight in grams, and small for gestational age (SGA) were evaluated. Analytical methods used included propensity score estimation, kernel matching, and weighted logistic and linear regressions. Race categories included Parda, which translates from Portuguese as “brown” and is used to denote individuals whose racial background is predominantly Black and those with multiracial or multiethnic ancestry, including European, African, and Indigenous origins.

RESULTS: A total of 4 277 523 live births (2 085 737 females [48.8%]; 15 207 among Asian [0.4%], 334 225 among Black [7.8%], 29 115 among Indigenous [0.7%], 2 588 363 among Parda [60.5%], and 1 310 613 among White [30.6%] mothers) were assessed. BFP was associated with an increase of 17.76 g (95% CI, 16.52-19.01 g) in birth weight. Beneficiaries had an 11% lower chance of LBW (odds ratio [OR], 0.89; 95% CI, 0.88-0.90). BFP was associated with a greater decrease in odds of LBW among subgroups of mothers who attended fewer than 7 appointments (OR, 0.85; 95% CI, 0.84-0.87), were Indigenous (OR, 0.73; 95% CI, 0.61-0.88), and had 3 or less years of education (OR, 0.76; 95% CI, 0.72-0.81). There was no association between BFP and SGA, except among less educated mothers, who had a reduced risk of SGA (OR, 0.83; 95% CI, 0.79-0.88).

CONCLUSIONS AND RELEVANCE: This study found that BFP was associated with increased birth weight and reduced odds of LBW, with a greater decrease in odds of LBW among higher-risk groups. These findings suggest the importance of maintaining financial support for mothers at increased risk of birth weight-related outcomes.
