Wound healing is a complicated multicellular process that involves several kinds of cells including macrophages, fibroblasts, endothelial cells, keratinocytes and platelets that are leading to their differentiation towards an anti-inflammatory response for producing several chemokines, cytokine and growth factors. In this study, electrospun nanofiber scaffold named (MNS) is composed of polyvinyl alcohol (PVA)/iota carrageenan (IC) and doped with partially reduced graphene oxide (prGO) that is successfully synthesized for wound healing and skin repair. The fabricated MNS was tested in case of infection and un-infection with E. coli and Staphylococcus and in both of the presence and in the absence of yeast as a natural nutritional supplement. Numerous biochemical parameters including total protein, albumin, urea and LDH, and hematological parameters were evaluated. Results revealed that the MNS was proved to be effective on most of the measured parameters and had exhibited efficient antibacterial inhibition activity. Whereas it can be used as an effective antimicrobial agent in wound healing, however, histopathological findings confirmed that the MNS caused re-epithelialization and the presence of yeast induced hair follicles growth and subsequently it may be used to hide formed head wound scar.

Cardiovascular-kidney-metabolic (CKM) syndrome, driven by metabolic risk factors like obesity, type 2 diabetes (DM-2), chronic kidney disease (CKD), and cardiovascular disease (CVD), leads to poorer health outcomes. Despite its rising prevalence and promising new therapies, trends and demographic disparities in CKM-related mortality among adults in the United States remain underexplored. The study examined CDC WONDER death certificates for individuals aged 25+ who died from 1999 to 2022, with CVD as the main cause, while CKD and DM-2 as contributing factors. Age-adjusted mortality rates (AAMRs) and annual percent change (APC) were calculated by year, sex, age, race/ethnicity, region, and urbanization status. From 1999 to 2022, 25,980 CKM-related deaths were recorded, with the AAMR decreasing from 5.3 to 0.4 per 1,000,000 population. AAMR rose significantly from 1999 to 2012 (APC: 7.03; p<0.001), sharply declined from 2012 to 2015 (APC: -65.55; p<0.001), and then increased from 2015 to 2022 (APC: 15.98; p = 0.101). Men had higher AAMRs than women (6.9 vs. 4.3), and older adults (65+) had the highest AAMR (23.3), followed by middle-aged adults (2.2). Among racial groups, non-Hispanic (NH) American Indian/Alaska Native had the highest AAMR (11.2), followed by NH Black (8.6), Hispanic (6.6), NH White (4.8), and NH Asian/Pacific Islander (4.7). Rural areas showed the highest AAMRs (6.8), compared to medium-small metro (6.1) and large metro areas (4.4). CKM-related mortality trends have varied widely over the past two decades, with men, older adults, American Indian/Alaska Native, and non-metropolitan populations experiencing the highest AAMRs, underscoring the need for targeted interventions.

ObjectivesTo identify all available studies assessing the use of portable ultrasound devices for pregnant women, with the specific aim of finding evidence for devices used to determine gestational age and their validity when compared with conventional ultrasound machines. We also wanted to determine what portable ultrasound models are commercially available for obstetric use.DesignSystematic scoping review.Primary and secondary outcome measuresExtracted variables included study design, population, method of ultrasound measurement, devices used and whether studies formally validated accuracy against conventional ultrasound.ResultsWe searched four databases—Medline, Embase, CINAHL and Maternal and Infant Care. In total 56 studies from 34 countries were identified; most were observational studies. Across all studies, 27 different portable ultrasound models (from 17 manufacturers) were evaluated. Twenty-one studies assessed use of portable ultrasound for evaluating fetal characteristics or estimating gestational age, and 10 of these were formal validation studies. In total, six portable devices have been validated for gestational age estimation against a conventional ultrasound comparator. The web searches identified 102 portable devices (21 manufacturers). These were a mix of handheld devices that connected to a phone or computer, or laptop-style portable ultrasound devices. Prices ranged from US$1190 to US$30 000 and weight ranged from 0.9 kg to 13.0 kg.ConclusionWhile the number of commercially available portable ultrasound devices continues to grow, there remains a lack of peer-reviewed, quality evidence demonstrating their accuracy and validity when compared with conventional ultrasound machines. This review identified some models that may be useful in gestational age estimation in low-resource settings, but more research is required to help implement the technology at scale.Trial registration numberRegistered via Open Science Framework (DOI: 10.17605/OSF.IO/U8KXP).

Introduction Induction of labor is a widely used obstetric intervention, with rates increasing globally. In Australia in 2022, over one‐third of women gave birth following the induction of labor. Though the rate of induction has increased, changes in methods and indications for induction have not been analyzed for the state of Victoria. This study aims to analyze these trends in Victoria, Australia. Material and Methods A retrospective cohort study was conducted using de‐identified data from the Victorian Perinatal Data Collection (VPDC) that includes all births statewide of at least 28 completed weeks' gestation from 2012 to 2020. The study analyzed trends in the onset of labor, methods used, and indications for induction over the study period, using descriptive statistics and average annual percentage change. Results A total of 701 324 births occurred during the study period, of which 223 672 (31.9%) were inductions. Induction of labor rates increased significantly from 25.4% in 2012 to 37.7% in 2020, with a notable rise at 38 and 39 weeks' gestation. Significant changes were observed in induction methods—the use of combination methods, particularly balloon catheter followed by pharmacological agents, increased, while the use of a standalone method declined. The findings suggest that gestational diabetes and fetal indications were major drivers of induction in recent years. Conclusions Labor induction practices in Victoria have changed significantly, reflecting shifts in clinical practices and changes in health profiles of pregnant women. Further research is needed to investigate the rising use of induction at early term gestation and the role of maternal preferences in driving induction in Victoria. The rate of induction of labor in Victoria increased between 2012 and 2020, notably at 38 and 39 weeks'. Significant changes were observed in induction methods and indications with gestational diabetes and fetal indications emerging as major drivers.

This study compared cardiovascular outcomes associated with metabolic and bariatric surgery (MBS) and glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy in individuals with obesity. The TriNetX network was used to compare cardiovascular risk in adult patients with BMI ≥35 who underwent MBS with those who received GLP-1 RA therapy for ≥2 years. Primary outcome was cardiovascular disease (CVD), a composite of incident heart failure (HF), coronary artery disease (CAD), and cerebrovascular disease. Patient follow-up lasted up to 10 years. MBS was associated with lower hazard of the primary composite outcome of CVD (HR, 0.54, 95 ​% CI, 0.49–0.60), and the secondary outcomes of incident HF (HR, 0.45, 95 ​% CI, 0.39–0.52), CAD (HR, 0.54, 95 ​% CI, 0.45–0.66), and cerebrovascular disease (HR, 0.64, 95 ​% CI, 0.53–0.77). A lower risk of adverse cardiovascular outcomes was noted after MBS compared with GLP-1 RA therapy in patients with obesity. [Display omitted] •Lower overall risk of adverse cardiovascular outcomes after MBS versus GLP-1 RA therapy.•Lower risk of coronary artery disease after MBS compared with GLP-1 RA therapy.•Lower cerebrovascular disease risk after MBS compared with GLP-1 RA therapy.•Lower risk of incident heart failure after MBS compared with GLP-1 RA therapy.

Postnatal care (PNC) is an essential component of maternity care. Appropriate and timely care immediately after childbirth can save lives and help to prevent or treat comorbidities resulting from pregnancy and childbirth. Despite its importance, PNC coverage is still low in Bangladesh. The aim of this study was to analyse the trends, inequalities, and factors associated with PNC for mothers in Bangladesh. Data from the last five Bangladesh Demographic and Health Surveys (BDHS) were used. Descriptive statistics were used to report PNC outcome rates and trends across six inequality indicators. Modified Poisson regression analyses were used to identify factors associated with PNC use in the most recent BDHS. A total of 21,240 women were included for the analysis. The rate of PNC by ‘medically trained provider’ within 2 days of birth increased between 2004 and 2017, from 16 to 52%. There were wide inequalities across socio-demographic factors. The regression analyses found women giving birth at home, women from the poorest wealth quintile and women receiving no antenatal care (ANC) were least likely to receive PNC. The findings emphasize the need to improve public health programs supporting women who have the least access to PNC. The identified inequalities can inform policy formulation to ensure more equitable provision of PNC to women in Bangladesh.

Paroxysmal tachycardia encompasses various heart rhythm disorders that cause rapid heart rates. Its episodic occurrence makes it difficult to identify and measure its prevalence and trends in the population. Additionally, there is limited data on disparities and trends in mortality due to paroxysmal tachycardia, which is essential for assessing current medical approaches and identifying at-risk populations. Our study examined death certificates from 1999 to 2020 using the CDC WONDER Database to identify deaths caused by paroxysmal tachycardia in individuals aged 25 and older, using the ICD-10 code I47. Age-adjusted mortality rates (AAMRs) and annual percent changes (APC) were calculated by year, gender, age group, race/ethnicity, geographic location, and urbanization status. Trends in AAMRs were analyzed using the Joinpoint Regression Program to identify significant changes and inflection points in mortality trends throughout the study period. Between 1999 and 2020, 155,320 deaths were reported in patients with paroxysmal tachycardia. Overall, AAMR decreased from 4.8 to 3.7 per 100,000 population between 1999 and 2020, despite showing a significant increase from 2014 to 2020 (APC: 4.33; 95% CI: 3.53 to 5.56). Men had consistently higher AAMRs than women (4.7 vs. 2.2). Furthermore, we found that AAMRs were highest among Non-Hispanic (NH) Black or African Americans and lowest in NH Asian or Pacific Islanders (4 vs. 1.9). Nonmetropolitan areas had higher AAMRs than metropolitan areas (3.6 vs. 3.2). Our analysis showed a significant decrease in mortality from paroxysmal tachycardia since 1999, although there has been a slight increase in recent years. However, disparities remain, with higher AAMRs among men, NH Black or African Americans, and residents of non-metropolitan areas. These findings call for immediate public health actions to curb the rising trends and reduce potential disparities.

Background Sample self-collection for reproductive tract infection diagnosis has been found to offer greater convenience, privacy, autonomy, and expanded access to testing in non-pregnant adults. This review aimed to determine whether sample self-collection is as accurate as provider-collection for detection of group B streptococcus colonisation in pregnancy and whether a strategy of self-collection compared to provider-collection might improve maternal and neonatal health outcomes. Methods We searched CINAHL Plus, Medline, EMBASE, Maternity and Infant Care Database, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews in June 2022. Eligible studies compared self-collected and provider-collected samples taken from the same participants or participants randomised to either self-collection or provider-collection for reproductive tract infection testing using the same test and testing method in pregnant individuals. We included trials and observational studies. Reviewers assessed risk of bias using the QUADAS-2 checklist and independently extracted data. Sensitivity and specificity for group B streptococcus colonisation of self-collected compared to provider-collected samples were pooled using a bivariate, random-effects, meta-analytic model. This review was registered with PROSPERO (CRD42023396573). Results The search identified 5909 references, of which eleven diagnostic accuracy group B streptococcus studies were included ( n  = 3269 participants). No studies assessed the effects of self-collection in pregnancy on health outcomes. All studies had high or unclear risk of bias. Pooled sensitivities of self-collected samples for group B streptococcus detection were 82% (95% CI: 66–91%; I 2  = 68.85%) in four trials ( n  = 1226) and 91% (95% CI: 83–96%; I 2  = 37.38%) in seven non-randomised studies ( n  = 2043). Pooled specificities were 99% (95% CI: 98–99%; I 2  = 12.08%) and 97% (95% CI: 94–99%; I 2  = 72.50%), respectively. Conclusions Self-collected samples for group B streptococcus detection in pregnancy had high specificity compared to provider-collection, but lower sensitivity, particularly for included trials. Studies investigating the effect of self-collection on health outcomes, and further higher quality trials comparing accuracy of self-collection to provider-collection, are required.

Background Wadi El Natrun microorganisms have been considered as a new resource for natural products due to its extreme condition of salinity and alkalinity. Therefore, this study was devoted to generate metagemic library from soils collected from such an extreme environment in order to clone a novel cellulase for physique industrial applications. Results Total soil-DNA was successfully extracted, and then digested by different restriction enzymes. Purified fragments ranged ~ 200-6500 bp were ligated and were cloned into plasmid cloning vector (pUC19) by using Escherichia coli DH5[alpha] (E. coli) host cells. A constructed metagenomic library composed of 270 clones was screened on carboxymethylcellulose (CMC) agar plate where the active clones had been characterized by the formation of the yellowish halo zone. Thereafter, clone 1 was selected as the most active as being based on cellulase activity quantification (19 [mu]/ml). Plasmid related to clone 1 encoded cellSNSY gene of approximately 1.5 kb was subjected to molecular characterization; the obtained partial sequence of 861 bps encoded 287 amino acids showing 76% similarity to the endoglucanase gene of Bacillus amyloliquefaciens. The recombinant cellSNSY was expressed under lacz promoter at 1 mM of isopropyl [beta]-d-1-thiogalactopyranoside (IPTG), giving 21 [mu]/ml cellulase after ~ 27 h. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and an activity staining of the recombinant cellSNSY which revealed an active band with a molecular mass ~ 59 kDa appeared in the induced sample. The maximum enzyme activity of crude cellSNSY was observed at 45 °C and for a pH of 8.5. Interestingly, the enzyme activity was slightly inhibited by ethylenediamine tetraacetic acid (EDTA) and methanol. It showed high resistance to the tested heavy metals and the surfactant which ordered Zn> (SDS,Fe)>Mn>Cu. Conclusions This study established an easy and a skillful way to clone/express a new found cellulase gene(s) under lacZ promoter. The isolated recombinant cellSNSY showed 76% similarity to endoglucanase gene, and the enzyme showed tolerance to the mostly tested agents including heavy metals, surfactant, solvents, and EDTA. Additionally, the studied recombinant showed a high stability up to 55 °C and for alkaline pH 8.5. These features make it an ample and viable for many applications.

Background and Aim There are many unknown consequences of viral infections. In this piece, we looked at one of these effects that influence the venous system of the body, vasculitis, an inflammation of the blood vessels. Discussion The study illustrates that viral infections attack host cells through viral proteins and surface receptors, activate NF‐kappaβ via various receptors and signaling pathways, and subsequently induce a cytokine storm through the release of various pro‐inflammatory cytokines, including IL‐6, TNF‐α, and CCL2, likely due to endothelial dysfunction caused by reactive oxygen species generation. Generally, overproduction of these mediators has been identified as a contributor to vascular inflammation and the subsequent development of atherosclerotic plaque, which may facilitate the initiation of vascular inflammation. This article also discusses potentially effective inhibitors for particular cytokines that contribute to vascular inflammation. Inhibiting the expression of these cytokines can diminish atherosclerotic lesions. Conclusion This article addresses the need for further investigation into the link between post‐viral infection effects and vascular inflammation by discussing the potential mechanism by which the immune system acts upon pathogen entry, the factors responsible for influencing the immune system, and the prevention of infectious disease transmission.
