Published: November 2022

Bacillus salmalaya 139SI and Lactobacillus sp. isolated from Kerinci buffalo milk yogurt were investigated for their potential probiotics properties. Three isolates from the milk yogurt were identified as L. plantarum 1, L. plantarum 2 and L. delbrueckii. The three isolates and B. salmalaya 139SI exhibited tolerance to gastric acid of pH 3.5, resistance to bile salts and were able to produce lactic acid. All the four strains exhibited antimicrobial activity against Salmonella Enteritidis, Escherichia coli and Staphylococcus aureus. Combination of isolates of L. plantarum 1 and L. plantarum 2 exhibited the highest coaggregation activity. L. plantarum 1 showed the highest hydrophobicity and had no adverse effects for the toxicity test (Lethal Dose 50). Characterization of probiotic properties in vitro and in vivo indicate that both bacteria L. plantarum and B. salmalaya 139SI are potential candidates for probiotic therapeutic application against Salmonella Enteritidis.

ImportanceThe 2021 expanded Child Tax Credit provided advance monthly payments to many US families with children from July through December 2021 and was associated with a reduction in food insufficiency. Less is known about the effect of the discontinuation of monthly payments.ObjectiveTo assess whether the discontinuation of monthly Child Tax Credit payments was associated with subsequent changes in food insufficiency among lower-income US households with children.Design, Setting, and ParticipantsThis population-based cross-sectional study used data from the Household Pulse Survey, a recurring online survey of US households conducted by the US Census Bureau, from January 2021 to March 2022. This study estimated difference-in-differences regression models for households making less than $50 000, less than $35 000, and less than $25 000 annually, adjusting for demographic characteristics and state of residence. The estimation sample of households making less than $50 000/y included 114 705 responses, representing a weighted population size of 27 342 296 households.ExposuresReceipt of monthly Child Tax Credit payments, as measured by living in a household with children during the period of monthly payments from July through December 2021.Main Outcomes and MeasuresHousehold food insufficiency, as measured by a respondent indicating that there was sometimes or often not enough food to eat in the household in the previous 7 days.ResultsAmong 114 705 households making less than $50 000/y, respondents were predominantly female (57%); White (71%); not of Hispanic, Latino, or Spanish origin (79%); had high school or equivalent education (38%); and were unmarried (70%). Following the discontinuation of monthly Child Tax Credit payments, food insufficiency in US households with children increased by 3.5 percentage points (95% CI, 1.4-5.7 percentage points) among households making less than $50 000/y, 4.9 percentage points (95% CI, 2.6-7.3 percentage points) among households making less than $35 000/y, and 6.2 percentage points (95% CI, 3.3-9.3 percentage points) among households making less than $25 000/y. These estimates represent a relative increase in food insufficiency of approximately 16.7% among households making less than $50 000/y, 20.8% among households making less than $35 000/y, and 23.2% among households making less than $25 000/y.Conclusions and RelevanceIn this population-based cross-sectional study, discontinuation of monthly Child Tax Credit payments in December 2021 was associated with a statistically significant increase in household food insufficiency among lower-income households, with the greatest increase occurring in the lowest-income households.

ImportanceReadmission is often considered a hospital quality measure, yet no validated risk prediction models exist for children.ObjectiveTo develop and validate a tool identifying patients before hospital discharge who are at risk for subsequent readmission, applicable to all ages.Design, Setting, and ParticipantsThis population-based prognostic analysis used electronic health record–derived data from a freestanding children’s hospital from January 1, 2016, to December 31, 2019. All-cause 30-day readmission was modeled using 3 years of discharge data. Data were analyzed from June 1 to November 30, 2021.Main Outcomes and MeasuresThree models were derived as a complementary suite to include (1) children 6 months or older with 1 or more prior hospitalizations within the last 6 months (recent admission model [RAM]), (2) children 6 months or older with no prior hospitalizations in the last 6 months (new admission model [NAM]), and (3) children younger than 6 months (young infant model [YIM]). Generalized mixed linear models were used for all analyses. Models were validated using an additional year of discharges.ResultsThe derivation set contained 29 988 patients with 48 019 hospitalizations; 50.1% of these admissions were for children younger than 5 years and 54.7% were boys. In the derivation set, 4878 of 13 490 admissions (36.2%) in the RAM cohort, 2044 of 27 531 (7.4%) in the NAM cohort, and 855 of 6998 (12.2%) in the YIM cohort were followed within 30 days by a readmission. In the RAM cohort, prior utilization, current or prior procedures indicative of severity of illness (transfusion, ventilation, or central venous catheter), commercial insurance, and prolonged length of stay (LOS) were associated with readmission. In the NAM cohort, procedures, prolonged LOS, and emergency department visit in the past 6 months were associated with readmission. In the YIM cohort, LOS, prior visits, and critical procedures were associated with readmission. The area under the receiver operating characteristics curve was 83.1 (95% CI, 82.4-83.8) for the RAM cohort, 76.1 (95% CI, 75.0-77.2) for the NAM cohort, and 80.3 (95% CI, 78.8-81.9) for the YIM cohort.Conclusions and RelevanceIn this prognostic study, the suite of 3 prediction models had acceptable to excellent discrimination for children. These models may allow future improvements in tailored discharge preparedness to prevent high-risk readmissions.

ImportanceEven with varenicline, the leading monotherapy for tobacco dependence, smoking abstinence rates remain low. Preliminary evidence suggests that extending the duration of varenicline treatment before quitting may increase abstinence.ObjectiveTo test the hypotheses that, compared with standard run-in varenicline treatment (1 week before quitting), extended run-in varenicline treatment (4 weeks before quitting) reduces smoking exposure before the target quit date (TQD) and enhances abstinence, particularly among women.Design, Setting, and ParticipantsThis double-blind, randomized, placebo-controlled clinical trial enrolled participants from October 2, 2017, to December 9, 2020, at a single-site research clinic in Buffalo, New York. Of 1385 people screened, 320 adults reporting smoking 5 or more cigarettes per day (CPD) were randomized and followed up for 28 weeks. Data were analyzed from August 2021 to June 2022.InterventionsIn the pre-TQD period (weeks 1-4), the extended run-in group received 4 weeks of varenicline; the standard run-in group received 3 weeks of placebo followed by 1 week of varenicline. Both groups received open-label varenicline during weeks 5 to 15 and brief quit counseling at 6 clinic visits.Main Outcomes and MeasuresThe primary outcome consisted of cotinine-verified (at end of treatment [EOT]) self-reported continuous abstinence from smoking (in CPD) during the last 4 weeks of treatment. Secondary outcomes included bioverified self-report of continuous abstinence at the 6-month follow-up and percentage of reduction in self-reported smoking rate during the prequit period (week 1 vs week 4).ResultsA total of 320 participants were randomized, including 179 women (55.9%) and 141 men (44.1%), with a mean (SD) age of 53.7 (10.1) years. Continuous abstinence during the final 4 weeks of treatment (weeks 12-15; EOT) was not greater in the extended run-in group (64 of 163 [39.3%]) compared with the standard run-in group (57 of 157 [36.3%]; odds ratio [OR], 1.13 [95% CI, 0.72-1.78]), nor was the hypothesized group × sex interaction significant (OR, 0.52 [95% CI, 0.21-1.28]). Similar nonsignificant results were obtained for continuous abstinence at the 6-month follow-up. The mean (SE) decrease in self-reported smoking rate during the prequit period was greater in the extended run-in group (−38.8% [2.8%]) compared with the standard run-in group (−17.5% [2.7%]).Conclusions and RelevanceAmong adult daily smokers, extending the duration of prequit varenicline treatment beyond the standard 1-week run-in period reduced prequit smoking exposure but, more importantly, did not significantly improve continuous abstinence rates.Trial RegistrationClinicalTrials.gov Identifier: NCT03262662
Reporting and Representativeness of Race, Ethnicity, and Socioeconomic Status in Systemic Sclerosis Randomized Trials: An Observational Study

Published: November 2022

ObjectiveTo assess how and to what extent socioeconomic status and ethnicity/race of participants are reported in randomized controlled trials (RCTs) on systemic sclerosis (SSc), and to estimate the representativeness of different ethnic/racial groups in SSc RCTs.MethodsWe searched all published RCTs on SSc indexed in PubMed. We retrieved information on main features of RCTs published from 2000 onward and recorded for each study whether race/ethnicity was reported; how ethnicity/race was defined and assigned; and the number of patients included for each racial/ethnic group. Multivariable logistic regression was used to identify factors associated with race/ethnicity reporting. Proportion of races/ethnicities included in US‐based RCTs on SSc was examined and compared with US demographic data.ResultsWe included 106 studies, mostly conducted in Europe (42%) or North America (25%), published after 2010 (74%), and enrolling a total of 6,693 patients. About one‐third of studies provided information about race/ethnicity, with no improved reporting over time. Only 2 papers reported patient's socioeconomic status. Study location (US or intercontinental) was the only significant factor associated with a better reporting of race/ethnicity in multivariable analysis. In studies where race/ethnicity was reported, White patients were mostly represented (79%), followed by Asian (7%), and African American (6%). In the sensitivity analysis limited to studies from the US, underrepresentation of African American patients was observed in the 2000–2010 time period, but not later.ConclusionDocumentation of race/ethnicity and socioeconomic status is poor in RCTs on SSc. More effort should be made to document race/ethnicity and socioeconomic status and to promote diversity in SSc RCTs.

AbstractSynergistically enhancing luminescent and ferroelectric (SELF) properties are observed from a tetraphenylethene (TP) substituted with clipping groups (C), where the C is consisting of a 4‐[3,5‐bis‐(3‐decyloxy‐styryl)‐styryl]‐phenyl (DOS) unit. The DOS units of TPCn are self‐assembled via intermolecular interaction to clip themselves and induce TP aggregation, as evidenced by clip‐induced quenching of emission at DOS units (Eclip) accompanied by aggregation‐induced emission enhancement of TPs (EAIE). TPC4 demonstrates strong photoluminescence in a dilute chloroform solution and large EAIE in aqueous (>50%) THF solution. TPCn demonstrates SELF properties in film state, with high quantum yields of photoluminescence (>80%) and ferroelectric switching. Due to the introduction of four clips, TPC4 has a higher remnant polarization (Pr  =  2.27 µC cm−2) at room temperature than TPC1. TPC4 is successfully employed in a light‐emitting electrochemical cell to achieve over 1290 cd m−2 under pulsed current conditions. The TPC4 film on a flexible substrate produced a piezoelectric output voltage of up to 0.13 V and a current density of 1.14 nA cm−2 upon bending. These results indicate that the side chain clipping and TP aggregation resulted in unprecedented flexible SELF properties in a single compound, offering simultaneous enhancement of electroluminescence, mechanical sensitivity, and energy harvesting capacity.

Published: November 2022

AbstractSoft robotic grippers achieve increased versatility and reduced complexity through intelligence embodied in their flexible and conformal structures. The most widely used soft grippers are pneumatically driven; they are simple and effective but require bulky air compressors that limit their application space and external sensors or computationally expensive vision systems for pick verification. In this study, a multi‐material architecture for self‐sensing electrohydraulic bending actuators is presented that enables a new class of highly versatile and reconfigurable soft grippers that are electrically driven and feature capacitive pick verification and object size detection. These electrohydraulic grippers are fast (step input results in finger closure in 50 ms), draw low power (6.5 mW per finger to hold grasp), and can pick a wide variety of objects with simple binary electrical control. Integrated high‐voltage driving electronics are presented that greatly increase the application space of the grippers and make them readily compatible with commercially available robotic arms.

Published: November 2022

AbstractCreating high‐speed soft actuators will have broad engineering and technological applications. Snapping provides a power‐amplified mechanism to achieve rapid movements in soft actuators that typically show slow movements. However, precise control of snapping dynamics (e.g., speed and direction of launching or jumping) remains a daunting challenge. Here, a bioinspired design principle is presented that harnesses a reconfigurable constraint structure integrated into a photoactive liquid crystal elastomer actuator to enable tunable and programmable control over its snapping dynamics. By reconfiguring constrained fin‐array‐shaped structure, the snapping dynamics of the structured actuator, such as launching or jumping angle and height, motion speed, and release force can be on‐demand tuned, thus enabling controllable catapult motion and programmable jumping. Moreover, the structured actuators exhibit a unique combination of ultrafast moving speed (up to 2.5 m s−1 in launching and 0.22 m s−1 in jumping), powerful ejection (long ejection distance of ≈20 cm, 35 mg ball), and high jumping height (≈8 cm, 40 times body lengths), which few other soft actuators can achieve. This study provides a new universal design paradigm for realizing controllable rapid movements and high‐power motions in soft matter, which are useful for building high‐performance soft robotics and actuation devices.

AbstractSlippery liquid‐impregnated porous surfaces (SLIPS) based smart windows (SWs) that dynamically fine‐tune the solar energy gain are promising candidates for alleviating the global energy crisis, especially for dim rainy climates. Unfortunately, the inferior durability arising from viscous dissipation over SLIPS‐based SWs remains a great challenge that needs to be addressed. Here, an ultra‐robust all‐solid‐state superhydrophobic SW is reported namely electric‐actuated reconfigurable shape memory shutter (EA‐RSMS) via a hybrid approach of laser ablation and soft transfer. Thanks to electrothermal effect of underlying silver nanowires heater, EA‐RSMS can be dynamically glazing by switching the surface shutters between bent mode (the transmittance of 10.8%) and erect one (the transmittance of 56.6%) within 60 s in situ. Synergistically, EA‐RSMS motivates the reversible transition between sticky state (sliding angle of 24°) and slippery one (sliding angle of 8°) by alternate Joule‐heating/pressing operation. Fundamental physics renders to clarify the effect of shutters topography on the hysteresis and light performance. Last but not the least, by utilizing the optimized EA‐RSMS shelter, indoor thermal‐comfort regulation, visibility encoding together with angle‐variable display are deployed. Current superhydrophobic EA‐RSMS with robust durability, novel tuning modulation, fast electric‐sensitivity, and optical angle‐dependence holds promising potential in self‐cleaning smart windows, energy‐saving buildings, anti‐voyeurism, etc.

AbstractGraphene‐based magnetic materials exhibit novel properties and promising applications in the development of next‐generation spintronic devices. Modern synthesis techniques have paved the way to design precisely the local environments of metal atoms anchored onto a nitrogen‐doped graphene matrix. Herein, it is demonstrated that grafting cobalt (Co) into the graphene lattice induces robust and stable room‐temperature ferromagnetism. These comprehensive experiments and first‐principles calculations unambiguously identify that the mechanism for this unusual ferromagnetism is π‐d orbital hybridization between Co dxz and graphene pz orbitals. Here, it is found that the magnetic interactions of Co–carbon ions are mediated by the spin‐polarized graphene pz orbitals, and room temperature ferromagnetism can be stabilized by electron doping. It is also found that the electronic structure near the Fermi level, which sets the nature of spin polarization of graphene pz bands, strongly depends on the local environment of the Co moiety. This is the crucial, previously missing, ingredient that enables control of the magnetism. Overall, these observations unambiguously reveal that engineering the atomic structure of metal‐embedded graphene lattices through careful d to p orbital interactions opens a new window of opportunities for developing graphene‐based spintronics devices.

AbstractSome of the major challenges for electronic skin (E‐skin) are to achieve accurate and continuous monitoring of human activities/health condition, eliminating wired external power sources. The ideal E‐skin should be ultra‐sensitive, self‐powered, conformal to human skin, and optically transparent for visual or aesthetic purposes. In this paper, a self‐powered all‐in‐one transparent E‐skin is constructed by integrating a flexible transparent supercapacitor (FTSC) as an energy storage device with a stretchable transparent strain sensor. The assembled FTSC uses oxygen‐deficient molybdenum oxide (MoOx) nanowires and cellulose nanofiber composite as paper electrodes, achieving an excellent combination of high transparency and outstanding energy‐storage capacity (12.1 mF cm−2) to drive the operation of the sensor. Meanwhile, the synergistic effect of 1D nanowires bridging 2D nanosheets in the skeleton network provides the transparent strain sensor with ultra‐high sensitivity (high gauge factor up to 220 under 1% strain), high signal‐to‐noise ratio, fast response time (≈50 ms), and excellent stability. The E‐skin being conformally attached to various parts of the human body enables real‐time detection of subtle physiological signals and joint movements.
