Authors: Wenze Susan J. , Mikula Cynthia M. , Battle Cynthia L. 
Published: February 2024

AbstractWe assessed prevalence and correlates of differential maternal‐infant bonding (i.e., experiencing a stronger bond with one baby vs. the other) in mothers of twins, focusing on aspects of maternal mental health, well‐being, and pregnancy/birth that have been previously linked with maternal‐infant bonding. Participants (N = 108 American women, 88.89% White, 82.41% non‐Hispanic, aged 18–45, who gave birth to twins in the past 6–24 weeks) were recruited from postpartum support websites. Participants completed a Qualtrics survey assessing pregnancy/birth history, symptoms of depression and anxiety, sleep, stress, romantic relationship satisfaction, and postpartum bonding. Twenty‐six participants (24.07%) reported a bonding discrepancy. These participants endorsed higher symptoms of depression and anxiety, lower relationship satisfaction, lower average postpartum bonding, higher general and parenting stress, and longer pregnancy (all ps > .05). Greater degree of bonding discrepancy correlated with more depression, higher parenting stress, longer pregnancy, and lower relationship satisfaction (all ps > .05). Mothers of twins may benefit from postpartum mental health support, stress management strategies, and interventions to improve bonding. Future work should assess the role of breastfeeding difficulties, delivery method, birth‐related trauma, infant regulatory capacity, and temperament. Longitudinal studies will help test cause and effect and potential long‐term repercussions of maternal‐infant bonding discrepancies.

The cover image focuses on a new class of solid electrolytes termed frameworked electrolytes, where the “macroscopically solid” frameworks are purposely laden with 3D ionic channels in the sub‐nano scales, giving rise to both a high ionic conductivity and a desirable interface with the electrode solids. The authors demonstrate a zeolite framework structure based frameworked electrolyte with superior ion diffusion kinetics, which ensures the design of high‐performance all solid state battery running at room temperature. It is confident that the emergence of frameworked electrolyte serves as a powerful motivator for embarking on a new expedition to design the next‐generation battery for EVs or portable electronics in the future.

How does the dramatic rise of nonresponse in the Current Population Survey impact labor market indicators?
Authors: Bernhardt Robert , Munro David , Wolcott Erin L. 
Published: February 2024

SummaryWithin a decade, the share of households refusing to participate in the Current Population Survey (CPS) tripled. We show households that refuse 1 month but respond in an adjacent month account for an important part of the rise. Leveraging the labor force status of survey participants in the months surrounding their nonresponse, we find that rising refusals suppressed the measured labor force participation rate and employment–population ratio but had little effect on the unemployment rate. Notably, nonresponse bias accounts for at least 10% of the reported decline in the labor force participation rate from 2000 to 2020.

AbstractBackgroundMeaning in life is a benchmark indicator of flourishing that can likely mitigate the severity of depression symptoms among persons seeking mental healthcare. However, patients contending with serious mental health difficulties often experience a painful void or absence of ultimate meaning in their lives that might hinder recovery. This two‐wave longitudinal study examined temporal associations between perceived presence of meaning in life, struggles with ultimate meaning, flourishing, and depression symptoms among adults in a spiritually integrated inpatient treatment program.MethodsOf the 242 patients assessed at intake, 90% (N = 218; 40% Cisgender male; 57% Cisgender female; 3.0% nonbinary) completed validated measures of these meaning‐related factors and mental health outcomes at discharge.ResultsCross‐sectional analyses revealed perceptions of meaning in life and ultimate meaning struggles were inversely linked with one another along with being associated with indices of positive and negative mental health in varying ways at the start and end of treatment. Drawing upon a two‐wave cross‐lagged panel design, longitudinal structural equation modeling analyses supported a Primary Meaning Model whereby having a subjective sense of meaning in life at intake was prospectively linked with lower levels of ultimate meaning struggles and greater flourishing at discharge. However, baseline levels of mental health outcomes were not predictive of the meaning‐related factors in this sample.ConclusionFindings highlight the utility of assessing patients' perceived meaning in life and ultimate meaning struggles in spiritually integrated programs and for clinicians to be prepared to possibly address these meaning‐related concerns in the treatment process.

AbstractBackgroundDifferentiating cardiovascular causes of dyspnea in resource‐limited healthcare settings can be challenging. The use of easy‐to‐train, point‐of‐care, focused cardiac ultrasound (FoCUS) protocols may potentially alleviate this challenge.Research QuestionCan novices attain competency in FoCUS use after training using the cardiac ultrasound for resource‐limited settings (CURLS) protocol?MethodsA quasi‐experimental study was conducted at the Kenyatta National Hospital in Nairobi, Kenya. Forty‐five graduate medical pre‐interns, novices in cardiac ultrasound, received simulated didactic and hands‐on FoCUS skills training using the CURLS protocol and 2018 European Association of Cardiovascular Imaging (EACVI) FoCUS training and competence assessment recommendations. Competency was assessed in image interpretation, image acquisition, and image quality.ResultsAggregate image interpretation competency was attained by n = 38 (84%) of trainees with a median score of 80%. The proportion of trainees attaining category‐specific image interpretation competency was as follows: pericardial effusion n = 44 (98%), left atrial enlargement n = 40 (89%), cardiomyopathy n = 38 (84%), left ventricular hypertrophy n = 37 (82%), and right ventricular enlargement n = 29 (64%). Image acquisition skills competency was attained by n = 36 (80%) of trainees. Three‐quarters of trainee‐obtained images were of good quality.ConclusionMajority of the trainees attained competency. Training constraints limit the generalizability of our findings.

AbstractCoccidiosis is a protozoan parasitic disease caused by Eimeria species and affects wild and domestic animals. Coccidiostats are currently available to control this disease, although drug resistance has been confirmed for all of them. As a result, there is an urgent need to identify eco‐friendly agents to control and treat this disease. This study aimed to investigate the ameliorative role of the Krameria lappacea roots extract (KLRE) on the outcome of coccidiosis induced by Eimeria papillata. Male C57BL/6 mice were divided into seven groups (5 mice/group), as follows: Group 1: noninfected‐nontreated (control group), Group 2: noninfected‐treated group with KLRE (200 mg/kg), Group 3: infected‐nontreated group, Group 4: infected‐treated group with KLRE (50 mg/kg), Group 5: infected‐treated group with KLRE (100 mg/kg), Group 6: infected‐treated group with KLRE (200 mg/kg), and Group 7: infected‐treated group with amprolium (120 mg/kg). Groups (3–7) were inoculated orally with 1 × 103 sporulated E. papillata oocysts. One hour after infection, groups (4–6) were daily treated for 5 days with KLRE and amprolium. On day 5 postinfection, oocyst output was determined, and mice were euthanized for the collection of jejuna then preparation of histological sections and jejunal homogenate was used for the determination of biochemical and oxidative damage markers. The coccidial infection induced weight loss of mice by 3.971%, which improved after KLRE to −1.512%. After KLRE treatment, the rate of feed intake was improved to be 52.21 ± 2.30 than those in infected group (40.47 ± 2.25). Oocyst output was significantly reduced in mice treated with KLRE (1.308 × 106 oocysts/g.feces) compared with those in the infected group (5.387 × 106 oocysts/g.feces). E. papillata infection induced marked histological alterations within jejunum tissue. After treatment, KLRE was able to impair the development of parasite stages (meronts, gamonts, and developing oocysts) in the jejunum through a significant reduction of number and size in comparison with the infected group. Infection with E. papillata induced a disturbance in the nutrient absorption in the jejunal mice tissue, which improved after the treatment with KLRE and amprolium. Also, KLRE counteracted significantly the E. papillata‐induced loss of reduced glutathione and total antioxidant capacity. Our findings indicate that KLRE could be used as an alternative to the available coccidiostats currently available.Research Highlights
Krameria lappacea exhibit significant anticoccidial and antioxidant activities induced by E. papillata infection.
Krameria lappacea exhibit significant improvement in the pathological alterations of the jejunal tissue induced by E. papillata infection.
Assessing factors that increase dusky gopher frog larval performance in open‐canopy wetlands
Authors: Lance C. Myles , Pechmann Joseph H. K. 
Published: February 2024

AbstractAmphibians are declining worldwide, and research on their habitats and ecology is important for their conservation. The endangered dusky gopher frog (Rana sevosa) breeds exclusively in isolated, open canopy wetlands, usually with extensive herbaceous growth. Larvae of the dusky gopher frog have higher growth and survival under open canopy than under closed canopy conditions. The mechanisms whereby this occurs are poorly understood, however. In the summer of 2021 in Harrison County, Mississippi, USA, we conducted a complete factorial experiment in mesocosms to compare the relative influence of factors differing between open and closed canopy ponds on larvae. A heat and light treatment consisted of one third of tanks being exposed to full sunlight, one third of tanks being shaded with 70% shadecloth, and the final third being shaded with 70% shadecloth but heated to mimic the temperature of the full sun tanks. In addition, tanks received a closed canopy tree leaf litter mixture or an open canopy herbaceous vegetation mixture, and vertical vegetation‐like structure made of polypropylene rope or not. Cool shaded tanks and heated shaded tanks had identical survival to metamorphosis at 74.7% and produced frogs with an average mass of 2.21 g and 2.09 g, respectively, while tanks in full sunlight achieved significantly higher 93.4% survival to metamorphosis and an average mass of 2.64 g. The open canopy vegetation mixture yielded an average tank survival of 88.3% and mass of 2.94 g, compared to closed canopy vegetation tanks with a significantly lower survival of 73.5% and average mass of 1.61 g. Added structure had no effect on survival or mass. These results indicate that sunlight (not heat alone) and herbaceous plants are important in increasing dusky gopher frog survival and mass in open canopy conditions and suggest that management for these characteristics receive priority in captive‐rearing programs and habitat restoration.

Published: February 2024

AbstractTerraced slopes are widely used in the Loess Plateau to control gully erosion, yet their potential to induce new erosion patterns remains overlooked. Here we used unmanned aerial vehicle (UAV) photogrammetry to obtain centimeter‐resolution digital surface models (DSMs) and derived hydrological networks, slopes, aspects, and curvatures of the terraced slopes. Our analysis reveals terraces disrupted natural water pathways, spurring new rill formations during each rainy season—a process neglected by models. Intriguingly, despite gentler gradients, terraced slopes exhibited higher erosion rates than steeper gullies, with widespread rills on terrace ridges. Vegetation‐induced deposition surpassed erosion by 1.52 times, but moisture evaporation on sunny slopes limited plant growth and enhanced erosion. We propose targeted strategies tailored to these erosion mechanisms, including terrace redesign, runoff diversion, slope strengthening, and suitable vegetation, advancing sustainable land management. However, this study faces limitations due to the reliance on drone photogrammetry, which may be influenced by environmental factors like varying solar angles and vegetation growth, and the lack of extensive field validation to support the UAV‐derived data. Our study spotlights drone photogrammetry's potential for elucidating complex erosion dynamics on terraced slopes.

AbstractThe phenology of critical biological events in aquatic ecosystems is rapidly shifting due to climate change. Growing variability in phenological cues can increase the likelihood of trophic mismatches (i.e., mismatches in the timing of peak prey and predator abundances), causing recruitment failures in important fisheries. We assessed changes in the spawning phenology of walleye (Sander vitreus) in 194 Midwest US lakes to investigate factors influencing walleye phenological responses to climate change and associated climate variability, including ice‐off timing, lake physical characteristics, and population stocking history. Ice‐off phenology shifted earlier, about three times faster than walleye spawning phenology over time. Spawning phenology deviations from historic averages increased in magnitude over time, and large deviations were associated with poor offspring survival. Our results foreshadow the risks of increasingly frequent natural recruitment failures due to mismatches between historically tightly coupled spawning and ice‐off phenology.
Preclustering Gelatin for Faster‐Forming Injectable Hydrogels: A Strategy for Fabricating 3D Hydrogel Scaffolds with Improved Cell Dispersion

Published: February 2024

AbstractGelatin‐based injectable hydrogels capable of encapsulating cells are pivotal in tissue engineering because they can conform to any geometry and exhibit physical properties similar to those of living tissues. However, the slow gelation process observed in these cell‐encapsulating hydrogels often causes an uneven dispersion of cells. This study proposes an approach for achieving fast gelation of unmodified gelatin under physiological conditions through gelatin preclustering. By using tetrafunctional succinimidyl‐terminated poly(ethylene glycol) as a clustering agent, the gelation process is successfully expedited fivefold without requiring chemical modifications, effectively addressing the associated challenges of uneven cell distribution.

Published: February 2024

AbstractDetrusor underactivity (DUA) is a common and thorny problem in urology, which severely impairs patients’ bladder function and quality of life. However, its underlying pathophysiological mechanism remains unclear. Hence, we sequenced 69,973 cells from five controls and nine patients with bladder dysfunction using single‐cell RNA sequencing. Twelve distinct cell types were identified and they showed high cellular and functional heterogeneity among each group. Among them, fibroblasts, macrophages, and epithelial cells had the most intercellular communications. Their aberrant gene expressions and altered intercellular interactions were mainly involved in extracellular matrix organization, inflammation/immune regulation, and cellular injury. Further re‐cluster analysis revealed an accumulation of the RBFOX1+ fibroblasts and RIPOR2+ macrophages in dysfunctional bladder wall, which mediated bladder remodeling through dysfunctional extracellular matrix organization and inflammation/immune reaction. Besides, the subtype of the epithelial cells was significantly altered. They underwent an intricate process including inflammation, damage, and repair during bladder remodeling. Overall, this work constructed the first single‐cell atlas for obstruction‐induced DUA, which could provide a valuable resource for deciphering the cellular heterogeneity and function changes in DUA, as well as potential strategies for bladder function improvement.

AbstractBackgroundThe RPGR gene has been associated with X‐linked cone‐rod dystrophy. This report describes a variant in RPGR detected with exome sequencing (ES). Genes like RPGR have not always been included in panel‐based testing and thus genome‐wide tests such as ES may be required for accurate diagnosis.MethodsThe Texome Project is studying the impact of ES in medically underserved patients who are in need of genomic testing to guide diagnosis and medical management. The hypothesis is that ES could uncover diagnoses not made by standard medical care.ResultsA 58‐year‐old male presented with retinitis pigmentosa, sensorineural hearing loss, and a family history of retinal diseases. A previous targeted gene panel for retinal disorders had not identified a molecular cause. ES through the Texome Project identified a novel, hemizygous variant in RPGR (NM_000328.3: c.1302dup, p.L435Sfs*18) that explained the ocular phenotype.ConclusionsContinued genetics evaluation can help to end diagnostic odysseys of patients. Careful consideration of genes represented when utilizing gene panels is crucial to ensure an accurate diagnosis. Medically underserved populations are less likely to receive comprehensive genetic testing in their diagnostic workup. Our report is an example of the medical impact of genomic medicine implementation.
Isolation enhancement of distinct element dual polarized compact MIMO antenna for 5G/WLAN application
Authors: Munusami Cholavendan , Venkatesan Rajeshkumar 
Published: February 2024

AbstractA novel‐shaped dual‐polarized low‐profile multiple‐input multiple‐output (MIMO) antenna with high isolation is proposed for 5G/WLAN application. An 8‐element MIMO antenna design comprises two unique planar radiators (chamfer, circular). Each radiator has dual feed and dual polarization characteristics. The prototype is fabricated with an FR‐4 dielectric substrate. A decoupling structure maintains desirable isolation for self‐isolated elements (−12 dB) using substrate integrated waveguide stubs between inter‐ports and high isolation among the adjacent radiating elements (−15 dB). The simulation was performed by using CST microwave studio. The simulated results of the proposed MIMO antenna are compared with the measurement results. Furthermore, ECC and DG are investigated.

AbstractConcentrations of the key metabolites of hepatic energy metabolism, adenosine triphosphate (ATP) and inorganic phosphate (Pi), can be altered in metabolic disorders such as diabetes mellitus. 31Phosphorus (31P)‐magnetic resonance spectroscopy (MRS) is used to noninvasively measure hepatic metabolites, but measuring their absolute molar concentrations remains challenging. This study employed a 31P‐MRS method based on the phantom replacement technique for quantifying hepatic 31P‐metabolites on a 3‐T clinical scanner. Two surface coils with different size and geometry were used to check for consistency in terms of repeatability and reproducibility and absolute concentrations of metabolites. Day‐to‐day (n = 8) and intra‐day (n = 6) reproducibility was tested in healthy volunteers. In the day‐to‐day study, mean absolute concentrations of γ‐ATP and Pi were 2.32 ± 0.24 and 1.73 ± 0.26 mM (coefficient of variation [CV]: 7.3% and 8.8%) for the single loop, and 2.32 ± 0.42 and 1.73 ± 0.27 mM (CVs 6.7% and 10.6%) for the quadrature coil, respectively. The intra‐day study reproducibility using the quadrature coil yielded CVs of 4.7% and 6.8% for γ‐ATP and Pi without repositioning, and 6.3% and 7.1% with full repositioning of the volunteer. The results of the day‐to‐day data did not differ between coils and visits. Both coils robustly yielded similar results for absolute concentrations of hepatic 31P‐metabolites. The current method, applied with two different surface coils, can be readily utilized in long‐term and interventional studies. In comparison with the single loop coil, the quadrature coil also allows measurements at a greater distance between the coil and liver, which is relevant for studying people with obesity.
