Authors: Remy Linda L. , Kaseff Louise , Shiau Rita , Clay Michael 
Published: January 2023

AbstractBackgroundMissing and noncodable parental industry and occupation (I/O) information on birth certificates (BCs) can bias analyses informing parental worksite exposures and family economic stability.MethodsWe used the National Institute for Occupational Safety and Health (NIOSH) software to code parental I/O in 1989–2019 California BC data (N = 21,739,406). We assessed I/O missingness and codability by reporting period, parental sex, race/ethnicity, age, and education.ResultsDuring 1989–2019, records missing I/O increased from 4.4% to 9.4%. I/O was missing more frequently from parents who were male (7.8% vs. 4.4%), Black or American Indian/Alaska Native (AIAN) (9.3% and 8.9% vs. 3.2%–4.7% in others), and had high school or less education (4.0%–5.9% vs. 1.4%–2.6% in others). Of records with I/O, less than 2% were noncodable by NIOSH software. Noncodable entries were more common for parents who were male (industry (1.9% vs. 1.0%); occupation (1.5% vs. 0.7%)), Asian/Pacific Islander (industry (2.4% vs. 1.2%–1.6% in other groups); occupation (1.7% vs. 0.7%–1.5% in other groups)), age 40 and older (industry (2.1% vs. 0.4%–1.7% in younger groups); occupation (1.7% vs. 0.3%–1.3% in younger groups)), and 4‐year college graduates (industry (2.0% vs. 1.0%–1.9% in other groups); occupation (1.7% vs. 0.5%–1.4%)).ConclusionsIn California BC, I/O missingness was systematically higher among parents who are male, Black, AIAN, less than 20 years old, and report no college education. I/O codability is high when information is reported, with small percentage disparities. Improving data collection is vital to equitably describe economic contexts that determine important family outcomes.

AbstractObjectivesRecent studies have evaluated COVID‐19 outbreaks and excess mortality by occupation sectors. Studies on SARS‐CoV‐2 infection across occupation and occupation‐related factors remain lacking. In this study, we estimate the effect of in‐person work on SARS‐CoV‐2 infection risk and describe SARS‐CoV‐2 seroprevalence among working adults.MethodsWe used Wave 1 data (May to June 2021) from CalScope, a population‐based seroprevalence study in California. Occupation data were coded using the National Institute for Occupational Safety and Health Industry and Occupation Computerized Coding System. Dried blood spot specimens were tested for antibodies to establish evidence of prior infection. We estimated the causal effect of in‐person work on SARS‐CoV‐2 infection risk using the g‐formula and describe SARS‐CoV‐2 seroprevalence across occupation‐related factors.ResultsAmong 4335 working adults, 53% worked in person. In‐person work was associated with increased risk of prior SARS‐CoV‐2 infection (risk difference: 0.03; [95% CI: 0.02−0.04]) compared with working remotely. Workers that reported job loss or who were without medical insurance had higher evidence of prior infection. Amongst in‐person workers, evidence of prior infection was highest within farming, fishing, and forestry (55%; [95% CI: 26%−81%]); installation, maintenance, and repair (23%; [12%−39%]); building and grounds cleaning and maintenance (23%; [13%−36%]); food preparation and serving related (22% [13%−35%]); and healthcare support (22%; [13%−34%]) occupations. Workers who identified as Latino, reported a household income of <$25K, or who were without a bachelor's degree also had higher evidence of prior infection.ConclusionsSARS‐CoV‐2 infection risk varies by occupation. Future vaccination strategies may consider prioritizing in‐person workers.

AbstractDie Reaktion der sauerstoffverbrückten frustrierten Lewis–Paare (FLPs) tBu2P−O−Si(C2F5)3 (1) und tBu2P−O−AlBis2 (2) mit Azobenzol unter UV‐Bestrahlung ergab eine selektive Komplexierung des cis‐Isomers. Das Additionsprodukt von 2 ist stabil, während das Addukt von 1 in Lösung ähnlich einer [3,3]‐ortho‐Benzidin‐Umlagerung durch Spaltung der N−N‐Bindung, Sättigung der Stickstoffatome mit Wasserstoffatomen und Bildung einer neuen Bindung zwischen zwei ortho‐Phenylkohlenstoffatomen isomerisiert. Ähnliche Umlagerungen finden mit verschiedenen para‐substituierten Azobenzolen (R=Me, OMe, Cl) und Di(2‐naphthyl)diazen statt, während ortho‐methylierte Azoverbindungen keine Addukte mit 1 bilden. Alle Addukte wurden mit multinuklearer NMR‐Spektroskopie und Elementaranalysen charakterisiert und der Mechanismus der Umlagerung mittels quantenchemischer Berechnungen untersucht.

AbstractWe report here the synthesis and structural characterization of the first binary iron arsenide cluster anion, [Fe3(As3)3(As4)]3−, present in both [K([2.2.2]crypt)]3[Fe3(As3)3(As4)] (1) and [K(18‐crown‐6)]3[Fe3(As3)3(As4)]⋅en (2). The cluster contains an Fe3 triangle with three short Fe−Fe bond lengths (2.494(1) Å, 2.459(1) Å and 2.668(2) Å for 1, 2.471(1) Å, 2.473(1) Å and 2.660(1) Å for 2), bridged by a 2‐butene‐like As4 unit. An analysis of the electronic structure using DFT reveals a triplet ground state with direct Fe−Fe bonds stabilizing the Fe3 core.

AbstractPhosphane, PH3—a highly pyrophoric and toxic gas—is frequently contaminated with H2 and P2H4, which makes its handling even more dangerous. The inexpensive metal–organic framework (MOF) magnesium formate, α‐[Mg(O2CH)2], can adsorb up to 10 wt % of PH3. The PH3‐loaded MOF, PH3@α‐[Mg(O2CH)2], is a non‐pyrophoric, recoverable material that even allows brief handling in air, thereby minimizing the hazards associated with the handling and transport of phosphane. α‐[Mg(O2CH)2] further plays a critical role in purifying PH3 from H2 and P2H4: at 25 °C, H2 passes through the MOF channels without adsorption, whereas PH3 adsorbs readily and only slowly desorbs under a flow of inert gas (complete desorption time≈6 h). Diphosphane, P2H4, is strongly adsorbed and trapped within the MOF for at least 4 months. P2H4@α‐[Mg(O2CH)2] itself is not pyrophoric and is air‐ and light‐stable at room temperature.

Published: January 2023

AbstractMelt‐quenched glasses of organic–inorganic hybrid crystals, i.e., hybrid glasses, have attracted increasing attention as an emerging class of hybrid materials with beneficial processability and formability in the past years. Herein, we present a new hybrid crystal, (Ph3PEt)3[Ni(NCS)5] (1, Ph3PEt+=ethyl(triphenyl)phosphonium), crystallizing in a polar space groupP1 and exhibiting thermal‐induced reversible crystal‐liquid‐glass‐crystal transitions with relatively low melting temperature of 132 °C, glass‐transition temperature of 40 °C, and recrystallization on‐set temperature of 78 °C, respectively. Taking advantage of such mild conditions, we fabricated an unprecedented hybrid glass‐ceramic thin film, i.e., a thin glass uniformly embedding inner polar micro‐crystals, which exhibits a much enhanced intrinsic second‐order nonlinear optical effect, beingca. 25.6 and 3.1 times those of poly‐crystalline1and KH2PO4, respectively, without any poling treatments.

Published: January 2023

AbstractThis paper studies full‐order impulsive observers for impulsive systems with unknown inputs. Two types of full‐order impulsive observers are designed respectively. The first type is Luenberger‐type impulsive observer (LIO). The second type is for the observed system with eliminable unknown input, where the impulsive observer is allowed to have nonidentical dynamic structure with the observed system. The conditions via the average dwell time technique are derived for the existence of these two types of impulsive observers. It is shown that in the LIO, the observer's state tracks the observed system's state in the sense of input‐to‐state stability (ISS). Specifically, the observer's state track completely the observed system's state if the unknown input trends to zero. While in the second type of impulsive observer, the observer's state tracks completely the observed system's state regardless of the unknown input trends to zero. Finally, three examples with simulations are presented to demonstrate the effectiveness of the theoretical results.

AbstractObjectivesThe objective of this study is to determine the optimal timing for device‐based infant circumcision under topical anaesthesia.Subjects/patientsWe include infants aged 1–60 days who were enrolled in a field study of the no‐flip ShangRing device at four hospitals in the Rakai region of south‐central Uganda, between 5 February 2020 and 27 October 2020.MethodsTwo hundred infants, aged 0–60 days, were enrolled, and EMLA cream was applied on the foreskin and entire penile shaft. The anaesthetic effect was assessed every 5 min by gentle application of artery forceps at the tip of the foreskin, starting at 10 min post‐application until 60 min, the recommended time to start circumcision. The response was measured using the Neonatal Infant Pain Scale (NIPS). We determined the onset and duration of anaesthesia (defined as <20% of infants with NIPS score >4) and maximum anaesthesia (defined as <20% of infants with NIPS score >2).ResultsOverall, NIPS scores decreased to a minimum and reversed before the recommended 60 min. Baseline response varied with age, with minimal response among infants aged 40 days. Overall, anaesthesia was achieved after at least 25 min and lasted 20–30 min. Maximum anaesthesia was achieved after at least 30 min (except among those aged >45 days where it was not achieved) and lasted up to 10 min.ConclusionThe optimal timing for maximum topical anaesthesia occurred before the recommended 60 min of waiting time. A shorter waiting time and speed may be efficient for mass device‐based circumcision.
Violence risk assessment of Sovereign Citizens: An exploratory examination of the HCR‐20 Version 3 and the TRAP‐18
Authors: Vargen Lee M. , Challacombe Darin J. 
Published: January 2023

AbstractSovereign Citizens comprise an understudied right‐wing extremist movement in the United States who have grown in notoriety in recent years due to several high‐profile instances of violence. Despite this, little empirical research has been conducted on Sovereign Citizens, including research on assessing their risk for violence. In this study, we sought to replicate and extend a prior study on Sovereign Citizen violence. Using open‐source data, we added several new cases to a pre‐existing dataset of violent and non‐violent Sovereign Citizen incidents, yielding a total sample of 107 cases, 69 of which were scored using the HCR‐20V3, and 83 of which were scored using the TRAP‐18. Our findings indicated that higher scores on both instruments were significantly associated with greater odds of cases being violent. We also observed that several risk factors occurred with significantly more frequency among violent cases than non‐violent ones. Implications for future research and professional practice are discussed.

Published: January 2023

AbstractColorectal cancer (CRC) is a common gastrointestinal malignancy with high morbidity and fatality. Chemotherapy, as traditional therapy for CRC, has exerted well antitumor effect and greatly improved the survival of CRC patients. Nevertheless, chemoresistance is one of the major problems during chemotherapy for CRC and significantly limits the efficacy of the treatment and influences the prognosis of patients. To overcome chemoresistance in CRC, many strategies are being investigated. Here, we review the common and novel measures to combat the resistance, including drug repurposing (nonsteroidal anti‐inflammatory drugs, metformin, dichloroacetate, enalapril, ivermectin, bazedoxifene, melatonin, and S‐adenosylmethionine), gene therapy (ribozymes, RNAi, CRISPR/Cas9, epigenetic therapy, antisense oligonucleotides, and noncoding RNAs), protein inhibitor (EFGR inhibitor, S1PR2 inhibitor, and DNA methyltransferase inhibitor), natural herbal compounds (polyphenols, terpenoids, quinones, alkaloids, and sterols), new drug delivery system (nanocarriers, liposomes, exosomes, and hydrogels), and combination therapy. These common or novel strategies for the reversal of chemoresistance promise to improve the treatment of CRC.

AbstractBackgroundThe significance of BRCA alterations has been implicated in the development of metastatic castration‐resistant prostate cancer (PC). The details of the frequency and significance of BRCA alterations in localized PC remain unknown. In this study, we investigated the frequency and clinical significance of BRCA alterations in localized PCs using an in‐house next‐generation sequencer (NGS) system.MethodsDNA was extracted from formalin‐fixed paraffin‐embedded tissues of surgical specimens from 126 patients with clinically localized PC who underwent radical prostatectomy. The mutation information of 164 cancer genes was analyzed using the PleSSision‐Rapid test. Both copy number (CN) variation and loss of heterozygosity of various genes, such as BRCA1 and BRCA2, were estimated and reported.ResultsNext‐generation sequencer analyses revealed that the BRCA2 CN was decreased in 17 patients (13.5%) and the BRCA1 CN in six (4.8%) patients. NGS‐based CN values were shown to be highly correlated with droplet digital PCR‐based CN values. Tissue‐specific BRCA expression investigated using the Human Protein Atlas showed that the decreased CN of BRCA2, but not BRCA1, is responsible for the decreased BRCA activity in PC. Ten of the 22 patients with decreased BRCA2 CN were presumed to have somatic heterozygous deletion. There were no observed associations between the heterozygous deletion of BRCA2 and various clinicopathological parameters. Furthermore, three of 10 patients developed biochemical recurrence within 3 months after surgery. Multivariate analyses revealed that the initial prostate‐specific antigen levels and BRCA2 CN were independent factors for biochemical recurrence.ConclusionOur results suggest that a decrease in BRCA2 CN may be used as a biomarker for predicting recurrence after surgery in localized PC. Early screening for somatic alterations in BRCA2 using NGS may help to broadly predict the risk of PC progression.

AbstractBackgroundCognitive difficulties have been described after chemotherapy for breast cancer, but there is no standard of care to improve cognitive outcomes in these patients. This trial examined the feasibility, tolerability, acceptability, and preliminary effects of memantine to prevent cognitive decline during chemotherapy for breast cancer.MethodsPatients with stage I–III breast cancer, scheduled for neo/adjuvant chemotherapy, completed a cognitive battery prior to and 4 weeks after completing chemotherapy. Memantine (10 mg BID) was administered concurrent with chemotherapy. Our primary cognitive outcome was visual working memory assessed by the Delayed Matching to Sample test. We used the Brief Medication Questionnaire to assess acceptability.ResultsOf 126 patients approached, 56 (44%) enrolled. Forty‐five (80%) received ≥1 dose of memantine and completed pre‐post assessments. Seventy‐six percent reported taking ≥90% of scheduled doses. Participants were mean age of 56, 77% White, and 57% had stage I disease. Sixty‐four percent had stable or improved Delayed Matching to Sample test scores. Stable or improved cognition was observed in 87%–91% across objective cognitive domain composite measures. Sixty‐six percent self‐reported stable or improved cognitive symptoms. There were seven greater than or equal to grade 3 adverse events; two were possibly related to memantine. Only 5% reported that taking memantine was a disruption to their lives.ConclusionsMemantine was well‐tolerated and consistently taken by a large majority of patients receiving breast cancer chemotherapy. The majority demonstrated stable or improved cognition from pre‐ to post‐assessment. Randomized trials are needed to determine memantine's efficacy to ameliorate cognitive loss.Trial RegistrationClinicalTrials.gov NCT04033419.

Authors: Omar Lama , Onfroy Thomas , Daniele Stéphane , Perret Noémie 
Published: January 2023

AbstractThis study describes the use of novel Cu/ZnO/ZnAl2O4/PAAH (PAAH=polyacrylic acid) hybrid nanomaterials for glycerol hydrogenolysis. Their elaboration by sol‐gel process either in one step or in two steps allowed to modulate their structural properties in terms of specific surface area, Lewis acidity, sizes and dispersion of copper nanoparticles. The presence of PAAH and aluminium during the synthesis particularly showed benefits in terms of dispersion and metal‐support interaction. The characterization of the catalyst surfaces in composition and size of the copper nanoparticles allowed to establish structure‐reactivity relationships. Their optimization allowed to reach remarkable conversions up to 96 % with selectivity towards 1,2‐propanediol of 83 %. A recyclability study also showed a possible reuse of these catalysts after a reactivation step.
Characterization of a Sub‐Atmospheric Pressure‐Inducing Micropump Based on Flow Rate and Gauge Pressure Measurements
Authors: Buglie William L. N. , Tamrin Khairul Fikri 
Published: January 2023

AbstractThe pumping mechanism in multi‐inlet microfluidic channels usually requires multiple micropumps to be separately attached to each inlet. Unfortunately, this may create fluid leakage resulting from a considerably high internal pressure. To address this, a passive sub‐atmospheric pressure‐inducing micropump is proposed and its performance is characterized as a function of the flow rate and the gauge pressure. With this pump, a sufficiently high flow rate is generated, comparable to some active‐piezoelectric micropumps. The gauge pressure is exponentially descending with time and can be crudely classified into three regions of high, moderate, and slow pressure‐release times. Overall, the stabilized pressure is identified within 70 s < t ≤ 300 s for slow rate mixing while rapid mixing is applicable at t ≤ 70 s.
Converting Fuel‐Synthesis Process Water to Aquaculture Feed by Purple Non‐Sulfur Bacteria

Published: January 2023

AbstractThe availability of agricultural wastewater in arid climes limits the possibility of exploiting purple non‐sulfur bacteria (PNSB) to recover aqua‐feed bioproducts. Thus, this study examines the feasibility of recovering such bioproducts using fuel‐synthesis process water (FSPW) as a feedstock. Experiments were performed under varying light conditions. The results revealed that PNSB cultured in the zero‐nitrogen feedstock had over 40 % protein content, contained substantial lipids and pigments, and reduced FSPW organics by over 70 %. The light intensity significantly impacted biomass constituents and treatment efficiency. The results are promising for the potential development of a circular economy to convert FSPW to aqua‐feed.

AbstractCoordination chemistry is a powerful method to synthesize supramolecular cages with distinct features that suit specific applications. This work demonstrates the synthesis of discrete, homochiral FeII2L3 cages via chirality‐driven self‐assembly. Specifically, the installation of chirality – at both the vertices and ligand backbones – allows the formation of discrete, homochiral FeII2L3 cages of different sizes via stereochemical control of the iron(II) centers. We observed that larger cages require multiple chiral centra (chiral ligands and vertices). In contrast, the formation of smaller cages is stereoselective with solely chiral ligands. The latter cages can also be formed from two chiral subcomponents, but only when they have matching chirality. Single‐crystal X‐ray diffraction of these smaller FeII2L3 cages revealed several non‐covalent interactions as a driving force for narcissistic chiral self‐sorting. This expected behavior was confirmed utilizing the shorter ligands in racemic form, yielding discrete, homochiral FeII2L3 cages formed in enantiomeric pairs.

Comprehensive SummaryA new class of near‐infrared (NIR) fluorescent organoboron AIEgens was successfully developed for latent fingerprints (LFPs) imaging. They exhibit real‐time and in situ high‐resolution imaging performance at 1—3 levels of LFPs by spraying method. In addition, we systematically elucidate the fingerprint imaging mechanism of these AIEgens. Significantly, the excellent level 3 structural imaging capabilities enable the application of them for analyzing incomplete LFPs and identifying individuals in different scenarios.
