This study examined how being abused by a current partner versus an ex-partner might affect psychological well-being and social support in a community sample of 398 women, half of whom had experienced abuse in the past 6 months. The impact of emotional and physical abuse was influenced by partner status, with emotional abuse being more detrimental to women abused by current partners and physical abuse being more detrimental to women abused by ex-partners. Emotional support was negatively related to depression in women abused by current partners, whereas practical support was negatively related to depression in women abused by ex-partners. The implications for interventions with abused women are discussed. [ABSTRACT FROM AUTHOR]

Objective: Population-level strategies to organize and deliver care may improve diabetes management. We conducted a multiclinic controlled trial of population management in patients with type 2 diabetes.Research Design and Methods: We created diabetic patient registries (n = 3,079) for four primary care clinics within a single academic health center. In the intervention clinic (n = 898), a nurse practitioner used novel clinical software (PopMan) to identify patients on a weekly basis with outlying values for visit and testing intervals and last measured levels of HbA1c, LDL cholesterol, and blood pressure. For these patients, the nurse practitioner e-mailed a concise patient-specific summary of evidence-based management suggestions directly to primary care providers (PCPs). Population changes in risk factor testing, medication prescription, and risk factor levels from baseline (1 January 2000 to 31 August 2001) to follow-up (1 December 2001 to 31 July 2003) were compared with the three usual-care control clinics (n = 2,181).Results: Patients had a mean age of 65 years, were mostly white (81%), and the majority were insured by Medicare/Medicaid (62%). From baseline to follow-up, the increase in proportion of patients tested for HbA1c (P = 0.004) and LDL cholesterol (P < 0.001) was greater in the intervention than control sites. Improvements in diabetes-related medication prescription and levels of HbA1c, LDL cholesterol, and blood pressure in the intervention clinic were balanced by similar improvements in the control sites.Conclusions: Population-level clinical registries combined with summarized recommendations to PCPs had a modest effect on management. The intervention was limited by good overall quality of care at baseline and temporal improvements in all control clinics. It is unknown whether this intervention would have had greater impact in clinical settings with lower overall quality. Further research into more effective methods of translating population registry information into action is required. [ABSTRACT FROM AUTHOR]

To better illuminate the elements of an effective community response to domestic violence, this study examined how survivors prioritized their help-seeking activities and what their priorities revealed about their patterns of need. This study expanded on Sullivan and Bybee's findings regarding the utility of community-based advocacy by examining whether the extent to which such advocacy was effective was dependent on the types of needs that survivors presented. Cluster analysis revealed five distinct subgroups of survivors: one focused primarily on activities to acquire housing, a second worked more on education and employment, a third focused heavily on legal issues, and two groups were characterized by survivors' level of activity across a variety of needs (high and low). Despite the varied constellations of needs survivors presented, broad-based advocacy enhanced survivors' effectiveness in mobilizing needed community resources. These findings suggest that comprehensive and individualized approaches to advocacy for battered women are essential. [ABSTRACT FROM AUTHOR]

OBJECTIVE. To determine the effects of large doses of aspartame on behavior, cognition, and monoamine metabolism in children with attention deficit disorder. DESIGN. A randomized, double-blind, placebo-controlled crossover study of unmedicated children meeting Diagnostic and Statistical Manual of Mental Disorders (3rd ed) criteria for attention deficit disorder. SETTING. Behavioral assessments were performed in the child's home by their parents and in the classroom by a teacher. Cognitive tests were administered and blood drawing was performed during a 2-day inpatient admission to our Children's Study Center. INTERVENTIONS. Administration of aspartame (single morning dose, 34 mg/kg) or placebo for alternate 2-week periods. MAIN OUTCOME MEASURES. Behavioral and cognitive tests included the Matching Familiar Figures Test (MFFT), Children's Checking Task (CCT), the Airplane Test, the Wisconsin Card Sorting Test (WCST), the Subjects Treatment Emergent Symptom Scale (STESS), the Multigrade Inventory for Teachers (MIT), and the Conners Behavior Rating Scale. Blood was drawn for complete blood cell count and liver function tests, as well as amino acid, methanol, formate, serotonin, and monoamine metabolite analyses, and urine was collected for measurement of catecholamine and monoamine metabolite excretion. RESULTS. No clinically significant differences between aspartame and placebo were found for the STESS, MIT, or Conners ratings, or for the MFFT, CCT, WCST, or Airplane cognition tests. Also, no differences were noted for any of the biochemical measures, except for the expected increase in plasma phenylalanine and tyrosine following aspartame. CONCLUSIONS. The findings indicate that aspartame at greater than 10 times usual consumption has no effect on the cognitive and behavioral status of children with attention deficit disorder. In addition, aspartame does not appear to affect urinary excretion rates of monoamines and metabolites. [ABSTRACT FROM AUTHOR]

We assessed the incidence of sexual violence, physical violence, physical health symptoms, gynecological symptoms, and risk behaviors for contracting an STD or HIV infection in women who had used a shelter for women with abusive partners. In addition, we investigated the relationships between sexual violence and the frequency of physical health symptoms, including specific gynecological symptoms. Results indicated that one fourth of the women interviewed had experienced sexual violence and nearly two thirds of the women had experienced physical violence in the past 6 months. The incidence of physical health symptoms, gynecological symptoms, and risk behaviors for exposure to STDs and HIV infection are presented. The correlations among sexual violence, physical violence, and experiences of physical health symptoms are also reported. This study is particularly valuable because previous research has not documented the relationship between sexual violence and physical health symptoms. [ABSTRACT FROM AUTHOR]

The conversion of low energy photons into high energy photons via triplet-triplet annihilation (TTA) photon upconversion (UC) has become a promising avenue for furthering a wide range of optoelectronic applications. Through the decades of research, many combinations of triplet sensitizer species and annihilator molecules have been investigated unlocking the entire visible spectrum upon proper pairings of sensitizer and annihilator identities. Here, we reflect upon the seminal works which lay the foundation for TTA-UC originating from solution-based methods and highlight the recent advances made within the solid state primarily focusing on perovskite-based triplet generation., (Copyright 2024 Colette M.

Despite increasing attention to the importance of examining factors that impact housing instability and homelessness, the field lacks a validated scale of housing instability. The current study examined the reliability and validity of a seven-item scale that measures housing instability. Data were taken from a larger study which implemented the Domestic Violence Housing First model across five domestic violence agencies in the Pacific Northwest. A total of 406 participants were interviewed every six months over a period of two years. A Spanish version of the scale was administered to Spanish-speaking participants. Results provide an overview of the psychometric functioning of the scale and support its utility in assessing housing instability and homelessness. Specifically, the scale demonstrated concurrent and predictive validity, and showed evidence of scalar equivalence over time and across both language and locality. The current scale is therefore a succinct and psychometrically sound measure of housing instability which can be used moving forward to track housing instability in English and Spanish speakers, as well as in urban and rural settings., Competing Interests: Disclosure statement No potential conflict of interest was reported by the author(s).

Perovskites have gained popularity both as the active material in photovoltaics and as bulk triplet sensitizers for solid-state triplet-triplet annihilation upconversion (TTA-UC). Prior to widespread implementation into commercial photovoltaics, an in-depth understanding of the environmental influences on device performance is required. To this point, the temperature-dependent structure-function properties of TTA-UC within methylammonium formamidinium lead triiodide (MAFA)/rubrene UC devices are explored. A strong temperature dependence of the underlying UC dynamics is observed, where the maximum UC efficiency is achieved at 170 K, reflecting the competition between triplet diffusion length, diffusion rate, and triplet-triplet encounter events. A combination of spectroscopic and structural methods and theoretical modelling illustrates that despite the significantly increased carrier lifetime of the perovskite at low temperatures, the TTA-UC dynamics are not governed by the underlying sensitizer properties but rather limited by the underlying triplet diffusion.

Purpose: Stereotactic body radiation therapy (SBRT) has been used with high effectiveness in early-stage non-small cell lung cancer (NSCLC) but has not been studied extensively in locally advanced NSCLC. We conducted a phase 2 study delivering SBRT to the primary tumor followed by conventionally fractionated chemoradiation to the involved lymph nodes for patients with node-positive locally advanced NSCLC. This manuscript serves as both a guide to planning techniques used on this trial and the subsequent phase 3 study, NRG Oncology LU-008, and to report patient dosimetry and toxicity results., Methods and Materials: We initiated a phase 2 multicenter single arm study evaluating SBRT to the primary tumor (50-54 Gy in 3-5 fractions) followed by conventionally fractionated chemoradiation to 60 Gy in 2 Gy fractions with doublet chemotherapy to the involved lymph nodes for patients with stage III or unresectable stage II NSCLC. Patients eligible for adjuvant immunotherapy received up to 12 months of durvalumab. We report a detailed guide for the entire treatment process from computed tomography simulation through treatment planning and delivery. The dosimetric outcomes from the 60 patients who completed therapy on study are reported both for target coverage and normal structure doses. We also report correlation between radiation-related toxicities and dosimetric parameters., Results: Sixty patients were enrolled between 2017 and 2022. Planning techniques used were primarily volumetric modulated arc therapy for SBRT to the primary tumor and conventionally fractionated radiation to the involved nodes, with a minority of cases using dynamic conformal arc technique or static dynamic multileaf collimator intensity modulated radiation therapy. Grade 2 or higher pneumonitis was associated with lung dose V5 Gy > 70% and grade 2 or higher pulmonary toxicity was associated with lung dose V10 Gy > 50%. Only 3 patients (5%) experienced grade 3 or higher pneumonitis. Grade 2 or higher esophagitis was associated with esophageal doses, including mean dose > 20 Gy, V60 Gy > 7%, and D1cc > 55 Gy. Only 1 patient (1.7%) experienced grade 3 esophagitis., Conclusions: SBRT to the primary tumor followed by conventionally fractionated chemoradiation to the involved lymph nodes is feasible with planning techniques as described. Radiation-related toxicity on this phase 2 study was low. This manuscript serves as a guideline for the recently activated NRG Oncology LU-008 phase 3 trial evaluating this experimental regimen., (Copyright © 2023 American Society for Radiation Oncology.

As health care continues to change and evolve in a digital society, there is an escalating need for physicians who are skilled and enabled to deliver care using digital health technologies, while remaining able to successfully broker the triadic relationship among patients, computers and themselves. The focus needs to remain firmly on how technology can be leveraged and used to support good medical practice and quality health care, particularly around resolution of longstanding challenges in health care delivery, including equitable access in rural and remote areas, closing the gap on health outcomes and experiences for First Nations peoples and better support in aged care and those living with chronic disease and disability. We propose a set of requisite digital health competencies and recommend that the acquisition and evaluation of these competencies become embedded in physician training curricula and continuing professional development programmes., (© 2023 The Authors.

Importance: Intimate partner violence (IPV) is a leading cause of homelessness and a serious threat to public health and well-being., Objective: To determine whether the Domestic Violence Housing First (DVHF) model improves safety, housing stability, and mental health over 2 years., Design, Setting, and Participants: This longitudinal comparative effectiveness study interviewed IPV survivors and reviewed their agency records. All unstably housed or homeless IPV survivors entering domestic violence (DV) services were eligible to participate in the study, ensuring capture of typical variability in service delivery (eg, some survivors would enter services when agencies had the capacity to provide DVHF and others would receive services as usual [SAU]). Clients from 5 DV agencies (3 rural and 2 urban) referred by agency staff in a Pacific Northwest state of the United States were assessed between July 17, 2017, and July 16, 2021. Interviews were conducted in English or Spanish at entry into services (baseline) and at 6-, 12-, 18-, and 24-month follow-up visits. The DVHF model was compared with SAU. The baseline sample included 406 survivors (92.7% of 438 eligible). Of the 375 participants retained at the 6-month follow-up (92.4% retention), 344 had received services and had complete data across all outcomes. Three hundred sixty-three participants (89.4%) were retained at the 24-month follow-up., Intervention: The DVHF model has 2 components: housing-inclusive advocacy and flexible funding., Main Outcomes and Measures: Main outcomes included housing stability, safety, and mental health, which were assessed using standardized measures., Results: Of the 344 participants (mean [SD] age, 34.6 [9.0] years) included in the analyses, 219 (63.7%) received DVHF and 125 (36.3%) received SAU. Most participants identified as female (334 [97.1%]) and heterosexual (299 [86.9%]). Two hundred twenty-one participants (64.2%) were from a racial and ethnic minority group. Longitudinal linear mixed-effects models showed that receiving SAU was associated with greater housing instability (mean difference, 0.78 [95% CI, 0.42-1.14]), DV exposure (mean difference, 0.15 [95% CI, 0.05-0.26]), depression (mean difference, 1.35 [95% CI, 0.27-2.43]), anxiety (mean difference, 1.15 [95% CI, 0.11-2.19]), and posttraumatic stress disorder (mean difference, 0.54 [95% CI, 0.04-1.04]) compared with receiving the DVHF model., Conclusions and Relevance: Evidence in this comparative effectiveness study suggests that the DVHF model was more effective than SAU in improving the housing stability, safety, and mental health of survivors of IPV. The DVHF's amelioration of all of these interconnected public health issues-relatively quickly and with long-term continuance-will be of substantial interest to DV agencies and others working to support unstably housed IPV survivors.

Intimate partner violence (IPV) is a leading cause of homelessness, yet little evidence exists about effective strategies to assist IPV survivors as they work to avoid homelessness while freeing themselves from abuse. An ongoing demonstration evaluation is examining if and how one promising model assists IPV survivors in obtaining safe and stable housing over time. The Domestic Violence Housing First (DVHF) model involves providing IPV survivors with mobile advocacy and/or flexible funding, depending on individual needs, in order to attain these goals. We hypothesized that those receiving DVHF would experience greater housing stability and less re-abuse compared to survivors receiving services as usual. The current study evaluated the short-term efficacy of the DVHF model with a sample of 345 homeless or unstably housed survivors who sought services and who completed in-person interviews shortly after contacting the DV agency, as well as six months later. Those who received the DVHF model showed greater improvement in their housing stability compared to those receiving services as usual, as well as decreased economic abuse. Both groups experienced a sharp decline in all forms of abuse. The Domestic Violence Housing First model shows promise in helping unstably housed DV survivors achieve safe and stable housing. Study findings have implications for DV agencies as well as those funding such services. Understanding which interventions work best for which survivors is critical to ensuring that service providers are effectively working toward long-term housing stability and well-being for IPV survivors and their children., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest.

Pediatric Feeding Disorder, a common problem in children, is commoner in children with various developmental disorders. Children with pediatric feeding disorder can have food selectivity and lack dietary diversity (DD). In this paper, an understanding of DD in these children is provided along with a dietary diversity index that can be helpful in measuring and understanding the risks posed by this lack of DD. An overview of a management strategy to address decreased DD is proposed. In these children, improving DD can improve growth, micronutrient status, long-term metabolic health, and potentially quality of life., (© 2022.

Intimate partner violence (IPV) is a widespread and devastating phenomenon resulting in a myriad of long-term consequences for survivors and their children. IPV victimization not only has negative health and economic consequences, it has also been linked to homelessness and housing instability. In response, the Domestic Violence Housing First (DVHF) model is being used in some domestic violence (DV) agencies to help survivors attain safe and stable housing. The model includes using individualized advocacy and/or flexible funding to help survivors meet these goals. Using a longitudinal, quasi-experimental design, the current study involved conducting interviews with survivors and examining agency records to investigate the effectiveness of this model. We hypothesized that survivors who received DVHF would experience less re-abuse and greater housing stability over 12 months compared to those who received services as usual (SAU). The sample included 345 IPV survivors who had been homeless or unstably housed when they approached one of five DV programs for help. Interviews were spaced 6 months apart (when survivors first sought services as well as 6 months and 12 months later). Longitudinal analyses showed that survivors who received the DVHF model reported greater improvements in housing stability at both the 6-month and 12-month time points compared to those receiving SAU. At the 12-month time point, survivors who had received DVHF reported decreased physical, psychological, and economic abuse, as well as the use of their children against them as a form of abuse. This study adds to a growing body of evidence supporting this model's effectiveness and adds to our understanding of factors impacting the long-term housing stability and safety for IPV survivors.

Perovskite-sensitized triplet-triplet annihilation (TTA) upconversion (UC) holds potential for practical applications of solid-state UC ranging from photovoltaics to sensing and imaging technologies. As the triplet sensitizer, the underlying perovskite properties heavily influence the generation of spin-triplet states once interfaced with the organic annihilator molecule, typically polyacene derivatives. Presently, most reported perovskite TTA-UC systems have utilized rubrene doped with ∼1% dibenzotetraphenylperiflanthene (RubDBP) as the annihilator/emitter species. However, practical applications require a larger apparent anti-Stokes than is currently achievable with this system due to the inherent 0.4 eV energy loss during triplet generation. In this minireview, we present the current understanding of the triplet sensitization process at the perovskite/organic semiconductor interface and introduce additional promising annihilators based on anthracene derivatives into the discussion of future directions in perovskite-sensitized TTA-UC.

Since the advent of CT, iodinated contract media (ICM) has become one of the most regularly administered intravenous medications in clinical settings. Although considered generally safe, ICM is one of the most common causes of adverse drug reactions in clinical practice, accounting for more than 2 million adverse reactions worldwide. Currently, there are few useful tools to diagnose patient hypersensitivity, with the major limitation being the lack of consensus regarding the mechanisms of hypersensitivity to ICM. While there is an overwhelming abundance of literature pertaining to clinical features including incidence, symptomatology, and risk, few studies have further investigated the underlying mechanisms behind their clinical observations. Of the available literature discussing pathophysiology, most primary studies were completed over 20 years ago, since which the molecular characteristics of ICM have changed. Furthermore, many reviews mentioning pathophysiology fail to adequately emphasize the clinical importance of understanding the molecular pathways involved in hypersensitivity. In this review, we aim to emphasize the clinical relevance of pathophysiology as it relates to the prediction and diagnosis of hypersensitivity reactions to ICM. To this end, we will first briefly characterize hypersensitivity reactions to ICM with respect to epidemiology and clinical presentation. We will then present the existing evidence supporting various proposed mechanisms of hypersensitivity, highlighting the gaps that remain in the mechanistic delineation of both immediate and delayed reactions. Finally, we discuss the possibility of in vitro testing as a way to predict and diagnose hypersensitivity reactions, pending a more complete elucidation of mechanisms.

Intimate partner violence remains a significant public health issue and survivors often need various forms of support to achieve safety. The increased likelihood of experiencing housing instability and homelessness among survivors has led to an uptake in domestic violence agencies implementing housing-based interventions, such as Domestic Violence Housing First (DVHF), to address survivors' needs. The present study expands on prior research supporting the effectiveness of DVHF to examine situational factors that moderate the outcomes associated with this model among 406 survivors seeking services from domestic violence agencies located in the Pacific Northwestern region of the United States. Using latent profile analysis, participants were grouped into three latent classes: (a) "high abuse/instability," (b) "still affected," and (c) "doing better." Latent transition analysis was used to estimate the probability that participants would transition into a different latent class over time with social support (SS), material hardship, and receipt of DVHF services included as model predictors. Receipt of DVHF predicted improvements in survivors' safety, housing stability, mental health, and well-being, such that receiving DVHF was associated with higher odds of survivors transitioning into the "doing better" class. Social support and material hardship also emerged as significant factors predicting class membership, such that higher levels of social support and financial stability predicted membership in the "doing better" class. Additionally, social support and financial stability appeared to augment receipt of DVHF services, with DVHF being more strongly associated with positive outcomes among participants who also had high levels of social support and lower levels of material hardship.

One of the major limitations of solid-state perovskite-sensitized photon upconversion to date is that the only annihilator successfully paired with the perovskite sensitizer has been rubrene, raising the question of whether this appraoch of triplet sensitization is universal or limited in scope. Additionally, the inherent energetic mismatch between the perovskite bandgap and the rubrene triplet energy has restricted the apparent anti-Stokes shift achievable in the upconversion process. To increase the apparent anti-Stokes shift for upconversion processes, anthracene derivates are of particular interest due to their higher triplet energies. Here, we demonstrate successful sensitization of the triplet state of 1-chloro-9,10-bis(phenylethynyl)anthracene using the established formamidinium methylammonium lead triiodide perovskite FA 0.85 MA 0.15 PbI 3 , resulting in upconverted emission at 550 nm under 780 nm excitation. We draw a direct comparison to rubrene to unravel the underlying differences in the upconversion processes.

Housing instability is a critical concern in the United States, and domestic violence (DV) survivors are a group at high risk for experiencing housing instability or of becoming unhoused. Prior research has also identified having a criminal record (CR) as being a major barrier to obtaining stable housing, and this is truer for Black and Latinx people compared to their White counterparts. No study has examined whether comparable trends exist among survivors of DV, a group also at elevated risk of having a CR, sometimes related to their experience of abuse. The current exploratory study included 305 unhoused or unstably housed female DV survivors who had sought out DV support services. Multivariate regressions explored if survivor race and CR were separately linked to greater housing instability. CR was then explored as a potential moderator in the relation between race and housing instability. Results revealed that DV survivors with a CR faced greater housing instability than those without a CR, Black and Latina survivors experienced greater housing stability than did White survivors, and CR did not moderate the relation between race and housing instability. The racial differences were unexpected and are discussed in light of methodological limitations. This is the first study to date to explore the role of CR possession on housing instability for DV survivors.

Prenatal and preconception genetic counselors are trained to take patient pedigrees to evaluate for potential risks for genetic conditions, including hereditary cancer syndromes. However, little research has been published on how often prenatal/preconception genetic counselors provide recommendations for cancer genetic counseling solely based on a family history of cancer. Therefore, this study sought to (a) characterize the types of cancers recognized for a cancer genetic counseling recommendation, (b) analyze appointment indications associated with discussion documentation, and (c) investigate how often National Comprehensive Cancer Center (NCCN) genetic testing criteria for Hereditary Breast and Ovarian Cancer syndrome (HBOC) and Lynch syndrome were met and how often a recommendation for cancer genetic counseling was made. A retrospective chart review and pedigree analysis were performed for prenatal/preconception genetic counseling patients with a family history of cancer seen at two academic institutions between August 10, 2019, and December 1, 2019. In the 170 charts included, a recommendation for cancer genetic counseling was documented in 40% of all genetic counseling summaries and in 59.2% of summaries when NCCN genetic testing criteria for HBOC and/or Lynch syndrome was met. Using chi-squared and logistic regression analysis, these data support that individuals were significantly more likely to receive a recommendation when NCCN genetic testing criteria were met (OR = 5.01, p < .001) or when the family history contained two or more types of cancer (OR = 2.24, p = .02). Overall, this study identified the NCCN genetic testing criteria for HBOC and Lynch syndrome for which recommendations for cancer genetic counseling were commonly missed. This characterization suggests that continuing education for prenatal and preconception genetic counselors on updated NCCN guidelines may be helpful for improving rates of cancer genetic counseling referrals, uptake of genetic testing, and cancer screening recommendations., (© 2022 National Society of Genetic Counselors.)

Objectives: Neisseria gonorrhoeae is an exclusively human pathogen that commonly infects the urogenital tract resulting in gonorrhoea. Empirical treatment of gonorrhoea with antibiotics has led to multidrug resistance and the need for new therapeutics. Inactivation of lipooligosaccharide phosphoethanolamine transferase A (EptA), which attaches phosphoethanolamine to lipid A, results in attenuation of the pathogen in infection models. Small molecules that inhibit EptA are predicted to enhance natural clearance of gonococci via the human innate immune response., Methods: A library of small-fragment compounds was tested for the ability to enhance susceptibility of the reference strain N. gonorrhoeae FA1090 to polymyxin B. The effect of these compounds on lipid A synthesis and viability in models of infection were tested., Results: Three compounds, 135, 136 and 137, enhanced susceptibility of strain FA1090 to polymyxin B by 4-fold. Pre-treatment of bacterial cells with all three compounds resulted in enhanced killing by macrophages. Only lipid A from bacterial cells exposed to compound 137 showed a 17% reduction in the level of decoration of lipid A with phosphoethanolamine by MALDI-TOF MS analysis and reduced stimulation of cytokine responses in THP-1 cells. Binding of 137 occurred with higher affinity to purified EptA than the starting material, as determined by 1D saturation transfer difference NMR. Treatment of eight MDR strains with 137 increased susceptibility to polymyxin B in all cases., Conclusions: Small molecules have been designed that bind to EptA, inhibit addition of phosphoethanolamine to lipid A and can sensitize N. gonorrhoeae to killing by macrophages., (© The Author(s) 2022.

The process of photon upconversion promises importance for many optoelectronic applications, as it can result in higher efficiencies and more effective photon management. Upconversion via triplet-triplet annihilation (TTA) occurs at low incident powers and at high efficiencies, requirements for integration into existing optoelectronic devices. Semiconductor nanocrystals are a diverse class of triplet sensitizers with advantages over traditional molecular sensitizers such as energetic tunability and minimal energy loss during the triplet sensitization process. In this Perspective, we review current progress in semiconductor nanocrystal triplet sensitization, specifically focusing on the nanocrystal, the ligand shell which surrounds the nanocrystal, and progress in solid-state sensitization. Finally, we discuss potential areas of improvement which could result in more efficient upconversion systems sensitized by semiconductor nanocrystals. Specifically, we focus on the development of solid-state TTA upconversion systems, elucidation of the energy transfer mechanisms from nanocrystal to transmitter ligand which underpin the upconversion process and propose novel configurations of nanocrystal-sensitized systems., Competing Interests: The authors declare no competing financial interest., (© 2022 The Authors.

Using data from an ongoing longitudinal study, we examined the impact of the COVID-19 stay-at-home orders on a racially diverse population of unstably housed domestic violence (DV) survivors over time. Specifically, we examined survivors' safety, housing stability, and mental health before, during, and after the onset of COVID-19, and how demographic, social, and familial factors attenuated or exacerbated the effect of the stay-at-home orders. Approximately 300 participants were initially interviewed after they sought services from a DV agency, and then again, every 6 months over 2 years. COVID-19 stay-at-home orders occurred midway through the completion of this multi-year study. Longitudinal mixed effects models were estimated to examine the impact of COVID-19 on the safety, housing stability, and mental health of survivors over time. We also examined models with several time-varying (e.g., employment, income, social support, and number of children) and time-invariant (baseline outcome scores, racial/ethnic identity, education, and disability status) control variables. Results revealed that safety, housing stability and mental health were improving for study participants before the onset of the COVID-19 pandemic but plateaued after the stay-at-home orders were issued. Experiences of abuse, housing instability, and mental health symptomatology did not worsen as a result of the COVID-19 stay-at-home orders. Notably, social support and housing services emerged as important predictors of outcomes, such that participants who received housing-related services and greater social support reported less abuse, less housing instability, and lower mental health distress. COVID-19 temporarily disrupted the positive trajectory unstably housed DV survivors were experiencing in regard to safety, housing stability and mental health. These findings provide critical insight into the importance of service access during and after global catastrophes. Additional resources and support may be helpful in assisting survivors to return to their pre-pandemic recovery and growth trajectories., (© 2021 The Authors.

Background: Anticoagulants are high-risk medications and are a common cause of adverse events of hospitalized inpatients. The incidence of adverse events involving anticoagulants has remained relatively unchanged over the past two decades, suggesting that novel approaches are required to address this persistent issue. Electronic medication management systems (eMMSs) offer strategies to help reduce medication incidents and adverse drug events, yet poor system design can introduce new error types., Objective: Our objective was to evaluate the effect of the introduction of an electronic medical record (EMR) on the quality and safety of therapeutic anticoagulation management., Methods: A retrospective, observational pre-/poststudy was conducted, analyzing real-world data across five hospital sites in a single health service. Four metrics were compared 1-year pre- and 1-year post-EMR implementation. They included clinician-reported medication incidents, toxic pathology results, hospital-acquired bleeding complications (HACs), and rate of heparin-induced thrombocytopenia. Further subanalyses of patients experiencing HACs in the post-EMR period identified key opportunities for intervention to maximize safety and quality of anticoagulation within an eMMS., Results: A significant reduction in HACs was observed in the post-EMR implementation period (mean [standard deviation [SD]] =12.1 [4.4]/month vs. mean [SD] = 7.8 [3.5]/month; p  = 0.01). The categorization of potential EMR design enhancements found that new automated clinical decision support or improved pathology result integration would be suitable to mitigate future HACs in an eMMS. There was no significant difference in the mean monthly clinician-reported incident rates for anticoagulants or the rate of toxic pathology results in the pre- versus post-EMR implementation period. A 62.5% reduction in the cases of heparin-induced thrombocytopenia was observed in the post-EMR implementation period., Conclusion: The implementation of an EMR improves clinical care outcomes for patients receiving anticoagulation. System design plays a significant role in mitigating the risks associated with anticoagulants and consideration must be given to optimizing eMMSs., Competing Interests: None declared., (The Author(s).

The aryl hydrocarbon receptor (AHR) is required for vertebrate development and is also activated by exogenous chemicals, including polycyclic aromatic hydrocarbons (PAHs) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). AHR activation is well-understood, but roles of downstream molecular signaling events are largely unknown. From previous transcriptomics in 48 h postfertilization (hpf) zebrafish exposed to several PAHs and TCDD, we found wfikkn1 was highly coexpressed with cyp1a (marker for AHR activation). Thus, we hypothesized wfikkn1's role in AHR signaling, and showed that wfikkn1 expression was Ahr2 (zebrafish ortholog of human AHR)-dependent in developing zebrafish exposed to TCDD. To functionally characterize wfikkn1, we made a CRISPR-Cas9 mutant line with a 16-bp deletion in wfikkn1's exon, and exposed wildtype and mutants to dimethyl sulfoxide or TCDD. 48-hpf mRNA sequencing revealed over 700 genes that were differentially expressed (p < .05, log2FC > 1) between each pair of treatment combinations, suggesting an important role for wfikkn1 in altering both the 48-hpf transcriptome and TCDD-induced expression changes. Mass spectrometry-based proteomics of 48-hpf wildtype and mutants revealed 325 significant differentially expressed proteins. Functional enrichment demonstrated wfikkn1 was involved in skeletal muscle development and played a role in neurological pathways after TCDD exposure. Mutant zebrafish appeared morphologically normal but had significant behavior deficiencies at all life stages, and absence of Wfikkn1 did not significantly alter TCDD-induced behavior effects at all life stages. In conclusion, wfikkn1 did not appear to be significantly involved in TCDD's overt toxicity but is likely a necessary functional member of the AHR signaling cascade., (© The Author(s) 2022.

The entry of mammalian cells into the DNA synthesis phase (S phase) represents a key event in cell division 1 . According to current models of the cell cycle, the kinase CDC7 constitutes an essential and rate-limiting trigger of DNA replication, acting together with the cyclin-dependent kinase CDK2. Here we show that CDC7 is dispensable for cell division of many different cell types, as determined using chemical genetic systems that enable acute shutdown of CDC7 in cultured cells and in live mice. We demonstrate that another cell cycle kinase, CDK1, is also active during G1/S transition both in cycling cells and in cells exiting quiescence. We show that CDC7 and CDK1 perform functionally redundant roles during G1/S transition, and at least one of these kinases must be present to allow S-phase entry. These observations revise our understanding of cell cycle progression by demonstrating that CDK1 physiologically regulates two distinct transitions during cell division cycle, whereas CDC7 has a redundant function in DNA replication., (© 2022.

Domestic violence (DV) is a leading cause of homelessness for women, yet many DV agencies are just beginning to focus on helping clients stabilize their housing situations. The purpose of this study was to better understand the contexts and service needs of unstably housed and homeless DV survivors, to promote more efficient and successful service matching from DV agencies. We examined whether DV survivors could be grouped by particular features, histories, and contextual factors, and how these group differences impacted what they needed from DV agencies. The sample included 406 homeless and unstably housed DV survivors who had recently sought DV services. Latent class analysis supported the identification of four distinct classes: (1) highest disadvantages service seeker, (2) moderate disadvantages-criminal legal system service seeker, (3) moderate disadvantages service seeker, and (4) lower disadvantages service seeker. Additionally, we were able to profile each class, and test the types of services survivors in each class needed from agencies., (© 2021 The Authors.

Objective: A learning health care system (LHS) uses routinely collected data to continuously monitor and improve health care outcomes. Little is reported on the challenges and methods used to implement the analytics underpinning an LHS. Our aim was to systematically review the literature for reports of real-time clinical analytics implementation in digital hospitals and to use these findings to synthesize a conceptual framework for LHS implementation., Methods: Embase, PubMed, and Web of Science databases were searched for clinical analytics derived from electronic health records in adult inpatient and emergency department settings between 2015 and 2021. Evidence was coded from the final study selection that related to (1) dashboard implementation challenges, (2) methods to overcome implementation challenges, and (3) dashboard assessment and impact. The evidences obtained, together with evidence extracted from relevant prior reviews, were mapped to an existing digital health transformation model to derive a conceptual framework for LHS analytics implementation., Results: A total of 238 candidate articles were reviewed and 14 met inclusion criteria. From the selected studies, we extracted 37 implementation challenges and 64 methods employed to overcome such challenges. We identified common approaches for evaluating the implementation of clinical dashboards. Six studies assessed clinical process outcomes and only four studies evaluated patient health outcomes. A conceptual framework for implementing the analytics of an LHS was developed., Conclusion: Health care organizations face diverse challenges when trying to implement real-time data analytics. These challenges have shifted over the past decade. While prior reviews identified fundamental information problems, such as data size and complexity, our review uncovered more postpilot challenges, such as supporting diverse users, workflows, and user-interface screens. Our review identified practical methods to overcome these challenges which have been incorporated into a conceptual framework. It is hoped this framework will support health care organizations deploying near-real-time clinical dashboards and progress toward an LHS., Competing Interests: None declared., (Thieme.

Child maltreatment is a major public health issue in the United States. In the federal fiscal year 2017, approximately 7.5 million children were referred to child welfare services (CSW) in the nation. Developmental, emotional, behavioral, and cognitive problems are prevalent among children referred to CWS. For those in foster care, temporary or permanent placement frequently introduces additional instability into a child's already chaotic life, increasing their risk for deleterious physical and mental health outcomes. Limited research exists documenting the impact of efficacious culturally adapted parent training (PT) interventions aimed at serving low-income ethnic minority families involved in CWS. The objective of this study was twofold: to explicate how a culturally adapted PT intervention for diverse families involved in CWS was perceived by participants and to better understand how interventionists adapted to families' needs. In this study, we conducted in-depth interviews with 14 parents who had completed the adapted intervention, as well as all of the interventionists providing the intervention. A thematic analysis approach was used to analyze and interpret the data. Parents indicated the positive impact that the intervention had on enhancing their parenting skills, as well as their ability to cope with the challenges associated with having a child removed by CWS. Interventionists described the gradual adaptations they implemented, in an effort to increase its cultural and contextual relevance. Research findings are relevant to the family therapy field as they increase understanding about culturally adapted PT interventions for ethnic minority families within CWS contexts., (© 2020 Family Process Institute.)

Importance: The need for cancer rehabilitation is expected to continue to dramatically increase with the aging population and increasing number of cancer survivors. These survivors experience a wide range of physical limitations and symptoms that negatively affect their health and quality of life. Research is needed to determine the rate of adherence, reasons for non-adherence, and interventions to improve adherence to acute inpatient rehabilitation among patients with cancer. Objective: To evaluate the rate of adherence and reasons for non-adherence to acute inpatient rehabilitation in patients with cancer. Design, Setting, and Participants: This was a secondary analysis of a retrospective study that assessed medical complications in 165 patients with cancer who had a median length of stay of 11 days (interquartile range of 8-14) in acute inpatient rehabilitation. We reviewed the records of all consecutive patients who underwent acute inpatient rehabilitation from September 1, 2017 through February 28, 2018 at a large academic, quaternary National Cancer Institute-designated Cancer Center. Main Outcomes and Measures: We calculated the rehabilitation session adherence rate and descriptively summarized the reasons for non-adherence. Results: There were 78/165 (47%) patients that had 1 or more incomplete rehabilitation sessions due to medical complications. These patients had a median of 2 (interquartile range of 1-4) incomplete rehabilitation sessions. We noted other reasons for incomplete rehabilitation sessions in 146/165 (89%) patients, who had a median of 3 (interquartile range of 2-4) incomplete rehabilitation sessions. The median total number of days with incomplete rehabilitation sessions in the entire cohort was 2 (interquartile range 1-3). Conclusion and Relevance: Among patients with cancer undergoing acute inpatient rehabilitation, the adherence rate to 1-hour long intensive rehabilitation sessions were low due to medical complications and other reasons. This in turn affected compliance with the 3 hours of rehabilitation a day requirement for acute inpatient rehabilitation. Patients with cancer undergoing acute inpatient rehabilitation are medically complex and further research at multiple institutions with larger cohorts may be beneficial in further assessing adherence rates and reasons for non-adherence to improve participation in acute inpatient rehabilitation., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)

The COVID-19 pandemic has impacted the management of non-communicable diseases in health systems around the world. This study aimed to understand the impact of COVID-19 on diabetes medicines dispensed in Australia. Publicly available data from Australia's government subsidised medicines program (Pharmaceutical Benefits Scheme), detailing prescriptions by month dispensed to patients, drug item code and patient category, was obtained from January 2016 to November 2020. This study focused on medicines used in diabetes care (Anatomical Therapeutical Chemical code level 2 = A10). Number of prescriptions dispensed were plotted by month at a total level, by insulins and non-insulins, and by patient category (general, concessional). Total number of prescriptions dispensed between January and November of each year were compared. A peak in prescriptions dispensed in March 2020 was identified, an increase of 35% on March 2019, compared to average growth of 7.2% in previous years. Prescriptions dispensed subsequently fell in April and May 2020 to levels below the corresponding months in 2019. These trends were observed across insulins, non-insulins, general and concessional patient categories. The peak and subsequent dip in demand have resulted in a small unexpected overall increase for the period January to November 2020, compared to declining growth for the same months in prior years. The observed change in consumer behaviour prompted by COVID-19 and the resulting public health measures is important to understand in order to improve management of medicines supply during potential future waves of COVID-19 and other pandemics.

Rigorously evaluating community-based interventions for multiply marginalized populations is fraught with challenges under the best of circumstances. This manuscript describes the methodology chosen to evaluate an innovative model designed to help survivors of intimate partner violence obtain safe and stable housing. We justify the choice of evaluation design from a community psychology perspective and detail why we believe the multi-method, multi-source design, that also focuses on social context, will maximize ecological validity and, therefore, propel the scale-up of the intervention if it is found to be effective. Longitudinal data are being collected from program recipients over time, the advocates who worked with them, agency service records, and monthly documentation of agency resources on hand that can impact services provided. Special attention is focused on capturing contextual information that can impact program success. While randomized control trials are still too often heralded as "the gold standard" for measuring intervention effectiveness, we maintain that the current design, which was developed in partnership with key community stakeholders, holds more promise when evaluating many community-based programs., (© 2020 The Authors.

The ubiquitous use of flame retardant chemicals (FRCs) in the manufacture of many consumer products leads to inevitable environmental releases and human exposures. Studying toxic effects of FRCs as a group is challenging since they widely differ in physicochemical properties. We previously used zebrafish as a model to screen 61 representative FRCs and showed that many induced behavioral and teratogenic effects, with aryl phosphates identified as the most active. In this study, we selected 10 FRCs belonging to diverse physicochemical classes and zebrafish toxicity profiles to identify the gene expression responses following exposures. For each FRC, we executed paired mRNA-micro-RNA (miR) sequencing, which enabled us to study mRNA expression patterns and investigate the role of miRs as posttranscriptional regulators of gene expression. We found widespread disruption of mRNA and miR expression across several FRCs. Neurodevelopment was a key disrupted biological process across multiple FRCs and was corroborated by behavioral deficits. Several mRNAs (e.g., osbpl2a ) and miRs (e.g., mir-125b-5p), showed differential expression common to multiple FRCs (10 and 7 respectively). These common miRs were also predicted to regulate a network of differentially expressed genes with diverse functions, including apoptosis, neurodevelopment, lipid regulation and inflammation. Commonly disrupted transcription factors (TFs) such as retinoic acid receptor, retinoid X receptor, and vitamin D regulator were predicted to regulate a wide network of differentially expressed mRNAs across a majority of the FRCs. Many of the differential mRNA-TF and mRNA-miR pairs were predicted to play important roles in development as well as cancer signaling. Specific comparisons between TBBPA and its derivative TBBPA-DBPE showed contrasting gene expression patterns that corroborated with their phenotypic profiles. The newer generation FRCs such as IPP and TCEP produced distinct gene expression changes compared to the legacy FRC BDE-47. Our study is the first to establish a mRNA-miR-TF regulatory network across a large group of structurally diverse FRCs and diverse phenotypic responses. The purpose was to discover common and unique biological targets that will help us understand mechanisms of action for these important chemicals and establish this approach as an important tool for better understanding toxic effects of environmental contaminants., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Dasgupta, Dunham, Truong, Simonich, Sullivan and Tanguay.)

High-throughput phenotyping systems are powerful, dramatically changing our ability to document, measure, and detect biological phenomena. Here, we describe a cost-effective combination of a custom-built imaging platform and deep-learning-based computer vision pipeline. A minimal version of the maize (Zea mays) ear scanner was built with low-cost and readily available parts. The scanner rotates a maize ear while a digital camera captures a video of the surface of the ear, which is then digitally flattened into a two-dimensional projection. Segregating GFP and anthocyanin kernel phenotypes are clearly distinguishable in ear projections and can be manually annotated and analyzed using image analysis software. Increased throughput was attained by designing and implementing an automated kernel counting system using transfer learning and a deep learning object detection model. The computer vision model was able to rapidly assess over 390 000 kernels, identifying male-specific transmission defects across a wide range of GFP-marked mutant alleles. This includes a previously undescribed defect putatively associated with mutation of Zm00001d002824, a gene predicted to encode a vacuolar processing enzyme. Thus, by using this system, the quantification of transmission data and other ear and kernel phenotypes can be accelerated and scaled to generate large datasets for robust analyses., (© 2021 Society for Experimental Biology and John Wiley & Sons Ltd.)

The COVID-19 pandemic has required intensive care units to rapidly adjust and adapt their existing practices. Although there has a focus on expanding critical care infrastructure, equipment and workforce, plans have not emphasised the need to increase digital capabilities. The objective of this report was to recognise key areas of digital health related to the COVID-19 response. We identified and explored six focus areas relevant to intensive care, including using digital solutions to increase critical care capacity, developing surge capacity within an electronic health record, maintenance and downtime planning, training considerations and the role of data analytics. This article forms the basis of a framework for the intensive care digital health response to COVID-19 and other emerging infectious disease outbreaks.

Domestic violence shelters have historically gone beyond providing emergency residential space for survivors by assisting in obtaining future housing, employment, health care, child care, or legal services. Domestic violence shelters are expected to operate within an empowerment philosophy, with an understanding that survivors are self-determining, can identify their needs, and know what it takes to meet those needs. Recent research has indicated that, as many shelters have become more rigid in creating rules that survivors must follow to access and retain free temporary housing, the result has been survivors' feelings of disempowerment, the complete opposite of what was originally intended. This study builds on the small amount of research conducted regarding survivors' experiences of shelter rules by specifically examining how rules were perceived to affect empowerment. Seventy-three survivors from two domestic violence shelters were asked about their experiences around specific shelter rules relating to curfew, parenting, chores, time limits, food, alcohol, drugs, and medications. A transcendental phenomenological approach was used to analyze the qualitative data, seeking explanations of how survivors made meaning of the rules and how those rules influenced their empowerment. Among those survivors who found the rules problematic, three major themes emerged: (a) rules acted as barriers to carrying out their normal, day-to-day activities; (b) the shelter staff's flexibility with rules was based on contingencies; and (c) rules negatively affected their psychological well-being, and required them to engage in protective behaviors. Recommendations are made for the reexamination and restructuring of rules within domestic violence shelters.

Indwelling urinary catheters are common in health care settings and can lead to catheter-associated urinary tract infection (CAUTI). Long-term catheterization causes polymicrobial colonization of the catheter and urine, for which the clinical significance is poorly understood. Through prospective assessment of catheter urine colonization, we identified Enterococcus faecalis and Proteus mirabilis as the most prevalent and persistent co-colonizers. Clinical isolates of both species successfully co-colonized in a murine model of CAUTI, and they were observed to co-localize on catheter biofilms during infection. We further demonstrate that P. mirabilis preferentially adheres to E. faecalis during biofilm formation, and that contact-dependent interactions between E. faecalis and P. mirabilis facilitate establishment of a robust biofilm architecture that enhances antimicrobial resistance for both species. E. faecalis may therefore act as a pioneer species on urinary catheters, establishing an ideal surface for persistent colonization by more traditional pathogens such as P. mirabilis .
