Expanding Color Control of Anodically Coloring Electrochromes Based on Electron-Rich 1,4-Dihydropyrrolo[3,2-b]pyrroles.

Anodically coloring electrochromes have received attention in recent years as high-contrast alternatives to cathodically coloring electrochromes due to their superior optical contrast during electrochemical switching. While current systems represent significant progress for organic electrochromics, it is necessary to expand the structural diversity of these materials while simultaneously reducing the hazards associated with synthetic protocols. With these considerations in mind, a family of 1,4-dihydropyrrolo[3,2-b]pyrrole (DHPP) chromophores with varying functionalities along the 2,5-axis was envisioned to accomplish these goals. After predicting different absorbance traits as oxidized molecules with time-dependent density functional theory, DHPP chromophores with varying peripheral functionalities were synthesized in a single aerobic synthetic step via an iron-catalyzed multicomponent reaction and characterized as high-contrast chromophores. In solution, the DHPP chromophores absorb in the ultraviolet region of the electromagnetic spectrum, resulting in color-neutral L*a*b* color coordinates of ∼100, 0, 0. Upon chemical oxidation, each molecule transitions to absorb at various points across the visible spectrum based on the extent of electron-donating ability and can display five distinct colors. Importantly, the chromophores are redox-active and display switching capabilities with an applied electrochemical potential. In conjunction with building fundamental insights into molecular design of DHPP chromophores, the results and synthetic simplicity of DHPPs make them compelling materials for color-controlled high-contrast electrochromes.

Death and dying in pharmacy learners: A critical review.

PURPOSE: This review article is the first comprehensive evaluation of the available literature surrounding the education of death and dying in pharmacy schools. The purpose of this review was to describe the available literature and methods utilized regarding the emotional preparation for patient death in pharmacy education. PROCEDURES: Searches were performed in three pharmacy databases to identify articles that contained descriptions of activities related to death and dying education in pharmacy curriculums. FINDINGS: Eleven journal articles were reviewed, detailing activities in pharmacy education including simulations, didactic sessions, and an innovative "death over dessert" model. Evaluation methods varied, with surveys being most common, followed by reflection. Didactic courses demonstrated increased empathy and knowledge, while simulations compared to case-based activities improved skills, knowledge, and comfort levels with providing end-of-life care. Simulations often involved interprofessional groups, with third-year pharmacy students most evaluated. CONCLUSION: Pharmacy students were mainly exposed to death and dying scenarios through didactic courses or simulations, with limited longitudinal exposure. Research suggests that students may lack preparation for handling death-related situations, leading to trauma and dysfunction. While existing studies focus on outward effects like empathy, internal factors such as coping methods receive less attention. Unlike nursing and medicine literature, pharmacy education lacks comprehensive coverage of coping and emotional support strategies for death and dying scenarios. Additional focus should be placed on intentional incorporation of these topics into pharmacy curriculums.

IFNγ-IL12 axis regulates intercellular crosstalk in metabolic dysfunction-associated steatotic liver disease.

Obesity is a major cause of metabolic dysfunction-associated steatohepatitis (MASH) and is characterized by inflammation and insulin resistance. Interferon-γ (IFNγ) is a pro-inflammatory cytokine elevated in obesity and modulating macrophage functions. Here, we show that male mice with loss of IFNγ signaling in myeloid cells (Lyz-IFNγR2-/-) are protected from diet-induced insulin resistance despite fatty liver. Obesity-mediated liver inflammation is also attenuated with reduced interleukin (IL)-12, a cytokine primarily released by macrophages, and IL-12 treatment in vivo causes insulin resistance by impairing hepatic insulin signaling. Following MASH diets, Lyz-IFNγR2-/- mice are rescued from developing liver fibrosis, which is associated with reduced fibroblast growth factor (FGF) 21 levels. These results indicate critical roles for IFNγ signaling in macrophages and their release of IL-12 in modulating obesity-mediated insulin resistance and fatty liver progression to MASH. In this work, we identify the IFNγ-IL12 axis in regulating intercellular crosstalk in the liver and as potential therapeutic targets to treat MASH.

Geographic access to fertility counseling among adolescent and young adult women with cancer in North Carolina.

BACKGROUND: Fertility counseling is recommended for adolescent and young adult (AYA) women facing gonadotoxic cancer therapy. However, fertility care is subspecialized medical care offered at a limited number of institutions, making geographic access a potential barrier to guideline-concordant care. We assessed the relationship between geographic access and receipt of fertility counseling among AYA women with cancer. METHODS: Using data from the North Carolina Central Cancer Registry, we identified women diagnosed with lymphoma, gynecologic cancer, or breast cancer at ages 15-39 years during 2004-2015. Eligible women were invited to complete an online survey on various topics, including fertility counseling. Geographic access was measured, using geocoded addresses, as vehicular travel time from residence to the nearest fertility clinic available at diagnosis. Multivariable regression models were used to examine the association between travel time and receipt of fertility counseling by provider type: health care provider vs fertility specialist. RESULTS: Analyses included 380 women. Median travel time to a fertility clinic was 31 (IQR: 17-71) minutes. Overall, 75% received fertility counseling from a health care provider and 16% by a fertility specialist. Women who lived ≥30 minutes from a clinic were 13% less likely to receive fertility counseling by a health care provider (PR:0.87; 95% CI:0.75-1.00) and 49% less likely to receive counseling by a fertility specialist (PR:0.51; 95% CI:0.28-0.93). CONCLUSIONS: Women who lived further away from fertility clinics were less likely to receive fertility counseling. IMPACT: Interventions to improve access to fertility counseling should include strategies to alleviate the burden of geographic access.

The Effect of Duration on Performance and Perceived Fatigability During Acute High-Intensity Interval Exercise in Young, Healthy Males and Females.

Few studies have explored the kinetics of performance and perceived fatigability during high-intensity interval training, despite its popularity. We aimed to characterize the kinetics of fatigability and recovery during an 8 × 4-min HIIT protocol, hypothesizing that most muscle function impairment would occur during the initial four intervals. Fifteen healthy males and females (mean ± standard deviation; age = 26 ± 5 years, V̇O2max = 46.8 ± 6.1 mL·kg-1·min-1) completed eight, 4-min intervals at 105% of critical power with 3 min of rest. Maximal voluntary knee extension contractions (MVCs) coupled with electrical nerve stimulation were performed at baseline and after the first, fourth, and eighth intervals. MVC, potentiated twitch force (Pt), and Db10:100 ratio all declined throughout HIIT (p < 0.05). MVC sharply declined after interval 1 (-15 ± 9% relative to baseline; p < 0.05) and had only further declined after interval 8 (-26 ± 11%; p < 0.05), but not interval 4 (-19 ± 13%; p > 0.05). Pt and Db10:100 also sharply declined after interval 1 (Pt: -18 ± 13%, Db10:100: -14 ± 20%; p < 0.05) and further declined after interval 4 (Pt: -35 ± 19%, Db10:100: -30 ± 20%; p < 0.05) but not interval 8 (Pt: -41 ± 19%; Db10:100: -32 ± 18%; p > 0.05). Voluntary activation did not significantly change across the HIIT protocol (p > 0.05). Evoked force recovery was significantly blunted as more intervals were completed: after interval 1, Pt recovered by 7 ± 11% compared to -6 ± 7% recovery after interval 8 (p < 0.05). Ratings of perceived effort, fatigue, and leg pain rose throughout the session (p < 0.05 for each) and were greater (effort and fatigue) for females (p < 0.05). Otherwise, males and females exhibited similar performance fatigability kinetics, with contractile function declines blunted in response to additional intervals.

Emotion-related impulsivity and suicidal ideation and behavior in schizophrenia spectrum disorder: a pilot fMRI study.

Introduction: Suicidal ideation and behavior (SIB) are serious problems in people with schizophrenia spectrum disorders (SSD). Nevertheless, relatively little is known about the circuitry underlying SIB in SSD. Recently, we showed that elevated emotional impulsivity (urgency) was associated with SIB in SSD. Here we examined brain activity in people with SSD and elevated SIB. Methods: We tested 16 people with SSD who had low SIB and 14 people with high SIB on a task in which emotion regulation in response to affective pictures was implicitly manipulated using spoken sentences. Thus, there were neutral pictures preceded by neutral statements (NeutNeut condition), as well as negative pictures preceded by either negative (NegNeg) or neutral (NeutNeg) statements. After each picture, participants rated how unpleasant each picture was for them. The latter two conditions were compared to the NeutNeut condition. We compared the emotion-regulated condition (NeutNeg) to the unregulated condition (NeutNeut). Statistics were threshold using threshold free cluster enhancement (TFCE). Results: People in the low SIB group showed higher activation in this contrast in medial frontal gyrus, right rostral anterior cingulate, bilateral superior frontal gyrus/DLPFC, and right middle cingulate gyrus, as well as right superior temporal gyrus. Discussion: This study provides clues to the neural basis of SIB in SSD as well as underlying mechanisms.

MIS-C vs Incomplete Kawasaki's Disease in a 12-year-old Female: A Case Study.

Multisystem inflammatory syndrome in children (MIS-C) is a rare but severe post-infectious complication of SARSCoV- 2 that seems to occur most frequently two to six weeks after infection. MIS-C can present very similarly to Kawasaki's disease (KD) with symptoms such as a skin rash in addition to a prolonged fever. Here we present a case of a 12-year-old African American/Black female with incomplete KD presenting similarly to MIS-C. The patient presented with prolonged fever, eventually worsening to shock and cardiac dysfunction. We further review the similarities and differences between incomplete KD and MIS-C. Due to their similarities, it is important to keep these diagnoses on the differential when a child presents with a prolonged fever.

In silico screening identifies SHPRH as a novel nucleosome acidic patch interactor.

Nucleosomes are the fundamental unit of eukaryotic chromatin. Diverse factors interact with nucleosomes to modulate chromatin architecture and facilitate DNA repair, replication, transcription, and other cellular processes. An important platform for chromatin binding is the H2A-H2B acidic patch. Here, we used AlphaFold-Multimer to screen over 7000 human proteins for nucleosomal acidic patch binding and identify 41 potential acidic patch binders. We determined the cryo-EM structure of one hit, SHPRH, with the nucleosome at 2.8 Å. The structure confirms the predicted acidic patch interaction, reveals that the SHPRH ATPase engages a different nucleosomal DNA location than other SF2-type ATPases, and clarifies the roles of SHPRH's domains in nucleosome recognition. Our results illustrate the use of in silico screening as a high throughput method to identify specific interaction types and expands the set of potential acidic patch binding factors. All the screening data is freely available at: https://predictomes.org/view/acidicpatch.

Comparison of pain after prophylactic anticoagulant injections to prevent venous thromboembolism.

Subcutaneous injection of unfractionated heparin (UH) or low molecular weight heparin (LMWH) is frequently utilized for venous thromboembolism chemoprophylaxis. We previously discovered that nurses believe patients experience more pain with UH compared to the LMWH enoxaparin; however, no published studies that are appropriately powered exist comparing pain associated with subcutaneous chemoprophylaxis. Our objective was to assess if differences exist in pain associated with subcutaneous administration of UH and enoxaparin. We conducted an observational study of patients who underwent major abdominal surgery between 11/2017-4/2019. All patients received one of three prophylactic regimens: (1) UH only, (2) Initial dose of UH followed by enoxaparin, or (3) enoxaparin only. Of the 74 patients observed, 40 patients received UH followed by enoxaparin, 17 received UH only, and 17 received enoxaparin only. There was a significant difference in patients' mean perceived pain between subcutaneous UH and enoxaparin injections (mean post-injection pain after UH 3.3 vs. enoxaparin 1.5; p < 0.001). There was no significant difference in perceived pain for patients who received consecutive UH or enoxaparin injections. Differences in pain associated with different chemoprophylaxis agents may be an unrecognized driver of patient refusals of VTE chemoprophylaxis and may lead to worse VTE outcomes.

Entrustable Professional Activities in Palliative Medicine: A Faculty and Learner Development Activity.

Background: Faculty development (FD) is critical to the implementation of competency-based medical education (CBME) and yet evidence to guide the design of FD activities is limited. Our aim with this study was to describe and evaluate an FD activity as part of CBME implementation. Methods: Palliative medicine faculty were introduced to entrustable professional activities (EPAs) and gained experience estimating a learner's level of readiness for entrustment by directly observing a simulated encounter. The variation that was found among assessments was discussed in facilitated debrief sessions. Attitudes and confidence levels were measured 1 week and 6 months following debriefs. Results: Participants were able to use the EPA framework when estimating the learner's readiness level for entrustment. Significant improvements in attitudes and level of confidence for several knowledge, skill, and behavior domains were maintained over time. Conclusions: Simulated direct observation and facilitated debriefs contributed to preparing both faculty and learners for CBME and EPA implementation.

One N-glycan regulates natural killer cell antibody-dependent cell-mediated cytotoxicity and modulates Fc γ receptor IIIa / CD16a structure.

Both endogenous antibodies and a subset of antibody therapeutics engage Fc gamma receptor (FcγR)IIIa / CD16a to stimulate a protective immune response. Increasing the FcγRIIIa/IgG1 interaction improves the immune response and thus represents a strategy to improve therapeutic efficacy. FcγRIIIa is a heavily glycosylated receptor and glycan composition affects antibody-binding affinity. Though our laboratory previously demonstrated that natural killer (NK) cell N-glycan composition affected the potency of one key protective mechanism, antibody-dependent cell-mediated cytotoxicity (ADCC), it was unclear if this effect was due to FcγRIIIa glycosylation. Furthermore, the structural mechanism linking glycan composition to affinity and cellular activation remained undescribed. To define the role of individual amino acid and N-glycan residues we measured affinity using multiple FcγRIIIa glycoforms. We observed stepwise affinity increases with each glycan truncation step with the most severely truncated glycoform displaying the highest affinity. Removing the N162 glycan demonstrated its predominant role in regulating antibody-binding affinity, in contrast to four other FcγRIIIa N-glycans. We next evaluated the impact of the N162 glycan on NK cell ADCC. NK cells expressing the FcγRIIIa V158 allotype exhibited increased ADCC following kifunensine treatment to limit N-glycan processing. Notably, an increase was not observed with cells expressing the FcγRIIIa V158 S164A variant that lacks N162 glycosylation, indicating the N162 glycan is required for increased NK cell ADCC. To gain structural insight into the mechanisms of N162 regulation, we applied a novel protein isotope labeling approach in combination with solution NMR spectroscopy. FG loop residues proximal to the N162 glycosylation site showed large chemical shift perturbations following glycan truncation. These data support a model for the regulation of FcγRIIIa affinity and NK cell ADCC whereby composition of the N162 glycan stabilizes the FG loop and thus the antibody-binding site.

Caregiver recruitment strategies for interventions designed to optimize transitions from hospital to home: lessons from a randomized trial.

Challenges to recruitment of family caregivers exist and are amplified when consent must occur in the context of chaotic healthcare circumstances, such as the transition from hospital to home. The onset of the COVID-19 pandemic during our randomized controlled trial provided an opportunity for a natural experiment exploring and examining different consent processes for caregiver recruitment. The purpose of this publication is to describe different recruitment processes (in-person versus virtual) and compare diversity in recruitment rates in the context of a care recipient's hospitalization. We found rates of family caregiver recruitment for in-person versus virtual were 28% and 23%, respectively (p = 0.01). Differences existed across groups with family caregivers recruited virtually being more likely to be younger, white, have greater than high school education, and not be a spouse or significant other to the care recipient, such as a child. Future work is still needed to identify the modality and timing of family caregiver recruitment to maximize rates and enhance the representativeness of the population for equitable impact.

Mechanistic in silico explorations of the immunogenic and synergistic effects of radiotherapy and immunotherapy: a critical review.

Immunotherapy is a rapidly evolving field, with many models attempting to describe its impact on the immune system, especially when paired with radiotherapy. Tumor response to this combination involves a complex spatiotemporal dynamic which makes either clinical or pre-clinical in vivo investigation across the resulting extensive solution space extremely difficult. In this review, several in silico models of the interaction between radiotherapy, immunotherapy, and the patient's immune system are examined. The study included only mathematical models published in English that investigated the effects of radiotherapy on the immune system, or the effect of immuno-radiotherapy with immune checkpoint inhibitors. The findings indicate that treatment efficacy was predicted to improve when both radiotherapy and immunotherapy were administered, compared to radiotherapy or immunotherapy alone. However, the models do not agree on the optimal schedule and fractionation of radiotherapy and immunotherapy. This corresponds to relevant clinical trials, which report an improved treatment efficacy with combination therapy, however, the optimal scheduling varies between clinical trials. This discrepancy between the models can be attributed to the variation in model approach and the specific cancer types modeled, making the determination of the optimum general treatment schedule and model challenging. Further research needs to be conducted with similar data sets to evaluate the best model and treatment schedule for a specific cancer type and stage.

Severe sexual abuse in childhood and altered neurophysiological response to reward in female adults.

BACKGROUND: A relatively understudied but growing body of research indicates that individuals with a history of childhood trauma exhibit altered reward processing in adulthood. Research to date has focused on adversity broadly, with studies typically finding evidence of blunted response to rewards in adults with a history of childhood trauma. OBJECTIVE: Given the role of reward processing in risk for psychopathology and the particularly pathogenic nature of sexual abuse (SA), the present study sought to assess whether adults with a history of severe childhood SA exhibit altered neurophysiological response to rewards. PARTICIPANTS AND SETTING: Female adults (N = 105) were included from two study sites that used the same measures of childhood trauma (Childhood Trauma Questionnaire, CTQ), reward processing (Doors Task), and psychopathology (SCID). METHODS: Based on participants' CTQ and SCID responses, three groups were created: Severe SA (n = 36), Clinical Match (with comparable lifetime psychopathology but no-to-minimal SA history; n = 35), and Healthy Controls (n = 34). Group differences in RewP amplitude were assessed. RESULTS: The Severe SA group exhibited larger reward positivity (RewP) amplitude to monetary rewards than the Clinical Match and Healthy Control groups (partial ƞ2 = 0.06, p = .047). This effect remained after covarying for severity of other forms of childhood trauma. CONCLUSIONS: Our study found that severe SA in childhood was related to a heightened response to reward in adulthood. Furthermore, this was not attributable to the severity of other forms of early trauma or comorbid psychopathology. Future studies are needed to identify how heightened reward processing following severe childhood SA may be implicated in the onset and course of psychopathology.

Improving age-friendly advance care planning in primary care: Outcomes from a Pacific Northwest learning collaborative.

BACKGROUND: Advance care planning (ACP) is the process of having conversations with patients to ensure preferences are known and support patient healthcare goals. ACP and the Age-Friendly Health Systems (AFHS) Initiative's, "What Matters," are synergistic approaches to patient-centered conversations. Implementation and measurement of ACP in primary care (PC) are variables in quality and consistency. We examined whether participation in an ACP learning collaborative (LC) would improve knowledge and ability to conduct ACP discussions and increase the frequency of documented ACP in participating practices. METHODS: The WWAMI (Washington, Wyoming, Alaska, Montana, and Idaho) region Practice and Research Network (WPRN) and the Northwest Geriatrics Workforce Enhancement Center collaboratively organized a 9-month virtual LC. It consisted of 4 synchronous, 1.5-h sessions, technical support, and a panel of ACP experts. A Wilcoxon rank sum test assessed differences in knowledge from a pre-post survey. Documentation of ACP in the EHR was collected after at least one plan-do-study-act cycle. RESULTS: We enrolled 17 participants from 6 PC practices (3 hospital-affiliated; 3 Federally Qualified Health Centers) from the WPRN. Two practices did not complete all LC activities. There was a trend toward increased ACP knowledge and skills overall especially in having discussions patients and families (pre-mean 2.9 [SD = 0.7]/post-mean 4.0[SD = 1.1], p < 0.05). 4/6 practices observed an increase in EHR documentation post-collaborative (median 16.3%, IQR 1.3%-36.9%). CONCLUSIONS: The LC increased PC providers knowledge and skills of ACP and AFHS's What Matters, reported ACP EHR documentation, and contributed to practice change.

Measuring disability among U.S. adolescents and young adults: A survey measurement experiment.

Objective: Disability is identified in surveys using various question sets, with little understanding of reliability across these measures, nor how these estimates may vary across age groups, including adolescents and young adults (AYA). The purpose of this study was to assess AYA prevalence of disability using two disability question sets and reliability of these measures. Methods: AYA participants in the Policy and Communication Evaluation (PACE) Vermont Study completed a single-item disability question used in the National Survey on Health and Disability (NSHD) and Urban Institute's Health Reform Monitoring Survey (HRMS) and a six-item set on functioning (Washington Group-Short Set, WG-SS) from the National Health Interview Survey (NHIS) and National Survey on Drug Use and Health (NSDUH) in 2021. Prevalence was estimated for any disability and each disability domain in adolescents (ages 12-17) and young adults (ages 18-25) and compared with U.S. national estimates in NHIS and NSDUH. Results: Using the WG-SS, the prevalence of any disability was 17.0 % in PACE Vermont adolescents and 22.0 % in young adults, consistent with the national prevalence of adolescents in NSDUH (17.9 %) but higher than estimates of young adults in NHIS (3.9 %) and NSDUH (12.9 %). The single-item question provided lower estimates of disability (adolescents: 6.9 %; young adults: 18.5 %) than the WG-SS, with low positive agreement between measures. Discussion: The prevalence of disability in AYAs varies depending on measures used. To improve disability surveillance, it may be necessary to validate new disability questions, including among AYAs, to capture a broader range of disability domains.

HIV self-testing in India: implementation and qualitative evaluation of a web-based programme with virtual counsellor support.

INTRODUCTION: To achieve epidemic control of infectious diseases, engaging higher-burden populations with accessible diagnostic services is critical. HIV self-testing (HIVST) is a promising option. METHODS: We implemented an online HIVST programme for key populations across India. Eligible clients were 18 years or older, self-reported a negative or unknown HIV status and reported not taking antiretroviral therapy. Clients who reported a prior HIV diagnosis were not eligible to receive an HIVST kit. HIVST clients received kits via courier or in person at pre-determined pick-up points supported by trained counselling staff. Virtual counsellors engaged clients online and by phone and offered support to register, access, and complete HIVST free of cost. Virtual counsellors supported clients to report results and engage with follow-up services. Follow-up included linking clients with a positive result to confirmatory testing and HIV care services. We assessed programmatic data across HIV continuum outcomes and conducted a qualitative evaluation through interviews with purposively sampled clients. RESULTS: Between 30 June 2021 and 30 September 2022, 5324 clients ordered an HIVST kit (76% men, 13% women, 7% transgender people, 4% unknown gender). Of the 4282 clients reporting results (94% of those who received a kit), 6% screened positive, among whom 72% (n = 184) completed confirmatory testing. Themes from 41 client interviews included satisfaction about the convenience and privacy of services and the discreet nature of kit delivery. Respondents were drawn to the convenience of HIVST and appreciated gaining courage and comfort throughout the process from virtual counsellor support. For respondents who screened positive, challenges to care linkage included fearing judgemental questions from public providers and wanting more time before starting treatment. Clients shared concerns about kit accuracy and suggested that instructional materials be provided with more diverse language options. CONCLUSIONS: Web-based HIVST services with tailored support appeared to facilitate HIV service access and engagement of harder-to-reach populations across India. Assistance from a community-oriented counsellor proved important to overcome literacy barriers and mistrust  in order to support the HIVST process and service linkage. Learnings can inform global efforts to improve the critical step of diagnosis in achieving epidemic control for HIV and other infectious diseases.

Association of low carbohydrate diet score with the risk of type 2 diabetes in an Australian population: A longitudinal study.

AIMS: We aimed to assess the association of a low carbohydrate diet score (LCD) with the incidence of type 2 diabetes (T2D) using Melbourne Collaborative Cohort Study (MCCS) data. METHODS: Between 1990 and 1994, the MCCS recruited 41,513 people aged 40-69 years. The first and second follow-ups were conducted in 1995-1998 and 2003-2007, respectively. We analyzed data from 39,185 participants. LCD score was calculated at baseline as the percentage of energy from carbohydrate, fat, and protein. The higher the score the less percentage of carbohydrates contributed to energy intake. The association of LCD quintiles with the incidence of diabetes was assessed using modified Poisson regression, adjusted for lifestyle, obesity, socioeconomic and other confounders. Mediation of the association by adiposity (BMI) was assessed. RESULTS: LCD was positively associated with diabetes risk. Higher LCD score (p for trend = 0.001) was associated with increased risk of T2D. Quintile 5 (38 % energy from carbohydrates) versus quintile 1 (55 % energy from carbohydrates) showed a 20 % increased diabetes risk (incidence risk ratio (IRR) = 1.20 (95 % CI: 1.05-1.37)). A further adjustment for BMI (Body Mass Index) and WHR (Waist-to-Hip-Ratio) eliminated the association. Mediation analysis demonstrated that BMI mediated 76 % of the LCD & diabetes association. CONCLUSIONS: Consuming a low carbohydrate diet, reflected as a high LCD score, may increase the risk of T2D which is largely explained by obesity. Results highlight the need for further studies, including clinical trials investigating the effects of a low carbohydrate diet in T2D.

Memory as a foundation for approach and avoidance decisions: A fertile area for research.

Scant research has directly measured the extent episodic memory serves as the basis for decisions, particularly decisions to approach or avoid other people (i.e., social targets). In this theoretical paper, we survey the limited work showing the relationship between episodic memory and subsequent approach or avoidance decisions about social targets, including descriptions of significant limitations of past work. We then describe three important areas for future work in this domain (explicit memory, implicit memory, diagnosticity) as a framework to generate new foundational knowledge about the extent memory influences approach and avoidance decisions. Overall, the framework proposed in this work should lead to better understanding of the connection between memory and decision-making, especially decisions to approach or avoid social targets (i.e., other people).
