RESUMEN
BACKGROUND: Medical students have reported facing unique challenges in their academic journey that can have a significant impact on their mental health and wellbeing; therefore, their access to support services and wellbeing resources has been deemed crucial for dealing effectively with the various challenges they tend to face. While previous research has highlighted certain barriers affecting medical students' help-seeking and access to wellbeing support more generally, there is a pressing need for more in-depth research into the factors that may hinder or facilitate medical students' acceptability and uptake of the wellbeing resources available to them within institutional contexts. The current study aims to explore students' perceptions and utilization of wellbeing interventions and welfare resources within a medical school setting, as well as the factors influencing their help-seeking attitudes or behaviours. Additionally, it seeks to instigate medical students' deeper reflections on potential enhancements that could be applied to wellbeing resources so that they are better suited to address their needs. METHODS: This study employed a qualitative design, involving semi-structured interviews and a series of focus groups with medical students at the University of Nottingham (UK). Post-interview, focus groups were deemed necessary to gain deeper insights into emerging findings from the interviews regarding students' views on wellbeing support services. Qualitative data from the interviews was subjected to thematic analysis while a hybrid thematic analytic approach was applied for the focus group data in order to allow for both pre-defined themes from the interviews and newly emerging patterns to be identified and analysed in a combined manner. RESULTS: Twenty-five participants took part in the semi-structured interviews and twenty-two participants were recruited in a total of seven focus groups. Thematic analysis findings identified several key barriers to medical students' accessing wellbeing resources, including difficulties in finding relevant information, lengthy processes and difficulties receiving prompt help in urgent situations, learning environment issues, confidentiality concerns, and stigma around mental health. Student suggestions for the enhancement of wellbeing provision were centered around proposed improvements in the format that the relevant information was presented and in the structure underlying the delivery of support services. CONCLUSION: The study findings shed light on multi-faceted factors contributing to medical students' challenges in accessing support services; and provided a deeper understanding of medical students' wellbeing needs through a consolidation of their recommendations for the implementation of practical steps to address these needs. These steps can potentially inform key medical education stakeholders so that they can actively and proactively foster more supportive environments that may help improve medical students' help-seeking, as well as their acceptability and uptake of wellbeing services.

BACKGROUND: Photovoice is a form of visual ethnography intended to engage impacted communities in research followed by action to ameliorate the injustices under study. Photovoice has increased in use, especially in collaboration with Latinx communities addressing health inequities. The Latinx population comprises nearly 18% of the overall United States population and according to the census is projected to reach just under 30% by 2060. This diverse panethnic community faces significant structural barriers in accessing services. Racism and the resulting marginalization, specifically, contributes to limited access to recovery services and treatment. Making meaningful advances in substance use disorder training, intervention and policy necessitates learning alongside the Latinx community. METHODS: We partnered with a Latinx serving integrated behavioral health and primary care setting in Boston Massachusetts to explore barriers and facilitators to recovery using photovoice. Spanish-speaking Latinx adults with a substance use disorder participated. The group met for three photovoice sessions over a six-week period. Together group members critically analyzed photographs using the SHOWeD method. RESULTS: Findings indicate a sense of purpose and meaning, security, faith and housing are important elements of recovery. The results illustrated the importance of sources of connection in maintaining sobriety. Through this photovoice project, Latinx Spanish speaking participants highlighted barriers and facilitators to their substance use disorder recovery which spanned individual, community, and structural levels. CONCLUSIONS: The experiences and voices of the Latinx community are crucial to drive discussions that advance policy (e.g., housing stability and access), enhance providers' understanding of Latinx Spanish-speakers' substance use disorder recovery, and inform culturally and linguistically appropriate services. This study demonstrated that photovoice is highly acceptable and feasible among Latinx clients receiving substance use disorder services. Visual images related to housing, faith, etc. communicate challenges, power structures, as well as hopes to policymakers at multiple levels (e.g., institution/ agency, state).

Objective: To evaluate changes in health and health care utilization outcomes for Latinx adults with substance use and mental disorders receiving integrated behavioral and primary health care.Design: Study sample included enrollees who completed baseline, 6-month and 12-month assessments (n = 107). Study outcomes were depression symptom severity, anxiety symptom severity, illicit drug use, emergency department utilization and homelessness status. Pre-post analyses were conducted using paired t-test and McNemar test to examine changes in study outcomes. Multivariable regression model estimated through generalized estimating equations explored the influence of the intervention on study outcomes. Results were presented in adjusted odds ratios (AOR) and 95% confidence intervals (CI).Results: Participants were less likely to report depressive symptoms (AOR: 0.496, 95%CI: 0.296-0.832), less likely to report anxiety symptoms (AOR: 0.539, 95%CI: 0.329-0.884), and less likely to experience homelessness (AOR: 0.556, 95%CI: 0.328-0.943) at 6-month assessment compared to baseline. Participants were also less likely to report depressive symptoms (AOR: 0.378, 95%CI: 0.209-0.684), less likely to report anxiety symptoms (AOR: 0.471, 95%CI: 0.270-0.821), less likely to experience homelessness (AOR: 0.333, 95%CI: 0.189-0.587), and less likely to utilize the emergency department in the past 30 days (AOR: 0.397, 95%CI: 0.188-0.837) at 12-month assessment compared to baseline.Conclusions: Integrating culturally responsive behavioral and primary health care services is critical for addressing the needs of Latinx adults with mental and substance use disorders, and other chronic diseases. This initiative has the potential to reduce disparities in access to and engagement in care for Latinx adults.

Idiopathic pulmonary fibrosis (IPF) is a fatal disease of unknown cause that is characterized by progressive fibrotic lung remodeling. An abnormal emergence of airway epithelial-like cells within the alveolar compartments of the lung, herein termed bronchiolization, is often observed in IPF. However, the origin of this dysfunctional distal lung epithelium remains unknown due to a lack of suitable human model systems. In this study, we established a human induced pluripotent stem cell (iPSC)-derived air-liquid interface (ALI) model of alveolar epithelial type II (ATII)-like cell differentiation that allows us to investigate alveolar epithelial progenitor cell differentiation in vitro. We treated this system with an IPF-relevant cocktail (IPF-RC) to mimic the pro-fibrotic cytokine milieu present in IPF lungs. Stimulation with IPF-RC during differentiation increases secretion of IPF biomarkers and RNA sequencing (RNA-seq) of these cultures reveals significant overlap with human IPF patient data. IPF-RC treatment further impairs ATII differentiation by driving a shift toward an airway epithelial-like expression signature, providing evidence that a pro-fibrotic cytokine environment can influence the proximo-distal differentiation pattern of human lung epithelial cells. In conclusion, we show for the first time, the establishment of a human model system that recapitulates aspects of IPF-associated bronchiolization of the lung epithelium in vitro.

The internal medicine (IM) subinternship has been a long-established clinical experience in the final phase of medical school deemed by key stakeholders as a crucial rotation to prepare senior medical students for internship. Medical education has changed greatly since the first national curriculum for this course was developed in 2002 by the Clerkship Directors in Internal Medicine (CDIM). Most notably, competency-based medical education (CBME) has become a fixture in graduate medical education and has gradually expanded into medical school curricula. Still, residency program directors and empirical studies have identified gaps and inconsistencies in knowledge and skills among new interns. Recognizing these gaps, the Association of Program Directors in Internal Medicine (APDIM) surveyed its members in 2010 and identified four core skills essential for intern readiness. The Association of American Medical Colleges (AAMC) also published 13 core entrustable professional activities (EPAs) for entering residency to be expected of all medical school graduates. Results from the APDIM survey along with the widespread adoption of CBME informed this redesign of the IM subinternship curriculum. The authors provide an overview of this new guide developed by the Alliance for Academic Internal Medicine (AAIM) Medical Student-to-Resident Interface Committee (MSRIC).

Background: Hispanic/Latinx persons with alcohol and other drug disorders (AOD) have limited access to culturally competent continuity of care. To address this, the evidence-based smartphone recovery application Addiction-Comprehensive Health Enhancement Support System (A-CHESS) was translated and adapted for Latinx Spanish-speakers with AOD, developing CASA-CHESS. Objectives: This study examined the AOD and mental health outcomes for Latinx Spanish-speaking clients using the CASA-CHESS smartphone tool over a 6-month period, post-residential treatment. This single group, pre-post study design included seventy-nine male and female Spanish-speaking Latinx clients, equipped with CASA-CHESS as they completed residential AOD treatment. Primary outcome measures at baseline and 6-month follow-up included substance use and other mental health symptoms. Results: While over 70% of the sample reported past heroin use and alcohol use, clients had low baseline rates of substance use, depression and anxiety and elevated social support scores as they graduated from residential treatment. Overall participants maintained their relatively low baseline rates during the 6-month post-residential period while using the CASA-CHESS relapse prevention tool. Those who discontinued using CASA-CHESS within the first 4 months after leaving residential treatment reported higher rates of substance use as well as anxiety and depression symptoms than those using it for 4 or more months, suggesting that continued use of CASA-CHESS may contribute to maintenance of successes gained in treatment. Conclusions/Importance: CASA-CHESS may reduce the risk of relapse for Latinx Spanish-speakers following residential services and extend needed access to culturally and linguistically competent aftercare services for those with AOD.

With the expansion of urban centres in the mid-twentieth century and the post-1970 decrease in pesticides, populations of double-crested cormorants (Phalacrocorax auritus) and ring-billed gulls (Larus delawarensis) around Lake Ontario (Canada and USA) have rapidly rebounded, possibly to unprecedented numbers. Along with the use of traditional palaeolimnological methods (e.g. stable isotopes, biological proxies), we now have the capacity to develop specific markers for directly tracking the presence of waterbirds on nesting islands. Here, we apply the use of lipophilic sterols and stanols from both plant and animal-faecal origins as a reliable technique, independent of traditional isotopic methods, for pinpointing waterbird arrival and population growth over decadal timescales. Sterol and stanol concentrations measured in the guano samples of waterbird species were highly variable within a species and between the three species of waterbirds examined. However, cholesterol was the dominant sterol in guano, and phytosterols were also high in ring-billed gull guano. This variability highlights a specialist piscivorous diet for cormorants compared to a generalist, omnivorous diet for gulls, which may now often include grain and invertebrates from agricultural fields. A ratio that includes cholesterol and sitosterol plus their aerobically reduced products (cholestanol, stigmastanol) best explained the present range of bird abundance across the islands and was significantly correlated to sedimentary δ15N. Overall, we demonstrate the use of sterols and stanols as a direct means for tracking the spatial and temporal presence of waterbirds on islands across Lake Ontario, and probably elsewhere.

The purpose of the fourth year of medical school remains controversial. Competing demands during this transitional phase cause confusion for students and educators. In 2014, the Association of American Medical Colleges (AAMC) released 13 Core Entrustable Professional Activities for Entering Residency (CEPAERs). A committee comprising members of the Clerkship Directors in Internal Medicine and the Association of Program Directors in Internal Medicine applied these principles to preparing students for internal medicine residencies. The authors propose a curricular framework based on five CEPAERs that were felt to be most relevant to residency preparation, informed by prior stakeholder surveys. The critical areas outlined include entering orders, forming and answering clinical questions, conducting patient care handovers, collaborating interprofessionally, and recognizing patients requiring urgent care and initiating that care. For each CEPAER, the authors offer suggestions about instruction and assessment of competency. The fourth year of medical school can be rewarding for students, while adequately preparing them to begin residency, by addressing important elements defined in the core entrustable activities. Thus prepared, new residents can function safely and competently in supervised postgraduate settings.

The immune system plays an important role in enhancing an individual's ability to survive in a world inhabited by pathogens and parasites. The innate immune system is regulated by processes encoded in an individual's genome, providing an avenue for selection to act on this system, as well as the phenotypic relationships generated between this system and other traits of interest. While relationships between innate immunity and endocrine traits (e.g. testosterone) have been reported often in the literature, these relationships are complex and may differ under varying environmental conditions. To better understand the relative contribution of innate immunity (or an endocrine or behavioral trait) to a phenotypic correlation with another trait, an estimation of the underlying heritable genetic variation of the trait of interest is needed. An upper level estimate of the heritability of such traits can be obtained from calculating its repeatability. We conducted a literature review to determine how often repeated samples of measures of innate immune function were conducted and repeatability estimates obtained. This review revealed a very limited number of repeatability estimates, with a large range (0.0-0.9); estimates were exclusively from livestock that have undergone strong artificial selection. This observation of the present literature suggests more work is needed in non-domesticated and free-living animals to begin to understand the underlying genetic contribution of innate immune function to phenotypic correlations of interest (e.g. testosterone and immunity) to behavioral ecologists, evolutionary physiologists and ecoimmunologists.

OBJECTIVE: Addressing alcohol and other drug disorders and other mental disorders among adult Hispanics/Latinos is of critical concern, as they are one of the fastest-growing ethnic groups with a disproportionate rate of disease, mental disorders, and poverty. Although improvement in outcomes is associated with sustained participation in ongoing treatment for co-occurring alcohol and other drug disorders/mental disorders, continuing care is rare for these chronic conditions, especially for Latinos with more limited access to culturally and linguistically competent services. METHODS: The evidence-based smartphone recovery application Addiction-Comprehensive Health Enhancement Support System (A-CHESS) was translated and adapted for Spanish-speaking Latinos with alcohol and other drug disorders/mental disorders, thus developing CASA-CHESS to address a high level of need for services, high rates of relapse, and lack of existing culturally competent services for Latinos. RESULTS: Of the 79 Latino clients who completed residential treatment and received a smartphone equipped with CASA-CHESS, 26.6% discontinued using CASA-CHESS and 73.4% remained active for four or more months. CASA-CHESS usage was sustained over the four months across all three tenets of self-determination theory (competence, relatedness, and autonomy), with the most commonly utilized services being relevant to relatedness (e.g., messaging, discussion boards). CASA-CHESS clients demonstrated a similar pattern of usage to A-CHESS clients. CONCLUSIONS: Findings illustrate that Spanish-speaking Latinos with alcohol and other drug disorders/mental disorders will use a smartphone application to assist with their recovery, continuing their access to resources, case management, and quality information after leaving residential treatment. Consistent with previous findings, our results also emphasize the importance of social support during the four months post-discharge. Such evidence-based, theory-driven digital interventions may extend access to culturally and linguistically competent services.

During spring, increasing daylengths stimulate gonadal development in migratory birds. However, late-stage reproductive development is typically postponed until migration has been completed. The hypothalamic-pituitary-adrenal (HPA) axis regulates the secretion of glucocorticoids, which have been associated with pre-migratory hyperphagia and fattening. The HPA-axis is also known to suppress the hypothalamic-pituitary-gonadal (HPG) axis, suggesting the possibility that final transition into the breeding life history stage may be slowed by glucocorticoids. We hypothesized that greater HPA-axis activity in individuals preparing for migration may foster preparation for migration while simultaneously acting as a "brake" on the development of the HPG-axis. To test this hypothesis, we sampled baseline corticosterone (CORT), stress-induced CORT, and negative feedback efficacy of Dark-eyed Juncos (Junco hyemalis) in an overwintering population that included both migratory (J.h. hyemalis) and resident (J.h. carolinensis) individuals. We predicted that compared to residents, migrants would have higher baseline CORT, higher stress-induced CORT, and weaker negative feedback. Juncos were sampled in western Virginia in early March, which was about 2-4wk before migratory departure for migrants and 4-5wk before first clutch initiation for residents. Contrary to our predictions, we found that migrants had lower baseline and stress-induced CORT and similar negative feedback efficacy compared with residents, which suggests that delayed breeding in migrants is influenced by other physiological mechanisms. Our findings also suggest that baseline CORT is not elevated during pre-migratory fattening, as migrants had lower baseline CORT and were fatter than residents.

Robust sediment quality criteria require chemistry and toxicity data predictive of concentrations where population/community response should occur under known geochemical conditions. Understanding kinetic and geochemical effects on toxicant bioavailability is key, and these are influenced by infaunal sediment bioturbation. This study used fine-scale sediment and porewater measurement of contrasting infaunal effects on carbon-normalized SEM-AVS to evaluate safe or potentially toxic nickel concentrations in a high-binding Spartina saltmarsh sediment (4%TOC; 35-45 µmol-S2-·g(-1)). Two crustaceans producing sharply contrasting bioturbation--the copepod Amphiascus tenuiremis and amphipod Leptocheirus plumulosus--were cultured in oxic to anoxic sediments with SEM[Ni]-AVS, TOC, porewater [Ni], and porewater DOC measured weekly. From 180 to 750 µg-Ni·g(-1) sediment, amphipod bioturbation reduced [AVS] and enhanced porewater [Ni]. Significant amphipod uptake, mortality, and growth-depression occurred at the higher sediment [Ni] even when [SEM-AVS]/foc suggested acceptable risk. Less bioturbative copepods produced higher AVS and porewater DOC but exhibited net population growth despite porewater [Ni] 1.3-1.7× their aqueous [Ni] LOEC. Copepod aqueous tests with/without dissolved organic matter showed significant aqueous DOC protection, which suggests porewater DOC attenuates sediment Ni toxicity. The SEM[Ni]-AVS relationship was predictive of acceptable risk for copepods at the important population-growth level.

Prior work has demonstrated that personalized letters are effective at reducing opioid and benzodiazepine prescribing, but it is unclear whether If/when-then planning prompts would enhance this effect. We conducted a decedent-clustered trial which randomized 541 clinicians in Los Angeles County to receive a standard (n = 284), or comparator (n = 257) version of a letter with If/when-then prompts. We found a significant 12.85% (6.83%, 18.49%) and 8.32% (2.34%, 13.93%) decrease in the primary outcomes morphine (MME) and diazepam milligram equivalents (DME), respectively. This study confirms the benefit of planning prompts, and repeat letter exposure among clinicians with poor patient outcomes. Limitations include lack of generalizability and small sample size.

PURPOSE: Few studies have examined the relationship between the intersections of lesbian, gay, and bisexual (LGB) sexual orientation, Latine ethnicity, and lifetime suicide attempts in Latine individuals with substance use disorder. This study examines this intersection and controls for social determinants of health, mental health disorder symptoms, and substance use disorder symptoms in a sample of Latine adults entering treatment for co-occurring disorders. METHOD: Bivariate statistics and multivariate logistic regression were used to analyze assessment data (n = 360) from a bilingual/bicultural integrated behavioral health system serving Latine communities in Massachusetts to examine the relationship between sexual orientation, Latine ethnicity, and history of lifetime suicide attempts. We controlled for social determinants of health, mental health disorders, and substance use disorder (SUD) factors significantly associated with lifetime suicide attempts at the bivariate level. RESULTS: Over 27% of the sample and 35% of Puerto Ricans (PR) reported lifetime suicide attempts. The logistic regression identified that PR clients were 78% more likely to have attempted suicide in a lifetime compared to non-PR clients. Clients identifying as LGB were 3.2 times more likely to report having attempted suicide in their lifetime compared to heterosexual clients. Unemployed clients were 2.4 times more likely to report having attempted suicide in their lifetime compared to employed clients. CONCLUSION: Findings identify high rates of lifetime suicide attempts among LGBs and PRs entering SUD treatment. Targeted outreach and treatment efforts designed to address intersectionality for this underserved population are needed.

OBJECTIVES: This study aims to quantify the degree to which an underserved, Hispanic population in Los Angeles is impacted by SARS-CoV-2, and determine factors associated with paediatric seropositivity. DESIGN: Cross-sectional. SETTING: AltaMed, a Federally Qualified Health Center in Los Angeles. PARTICIPANTS: A random sample of households who had received healthcare at AltaMed Medical Group was invited to participate. Households with at least one adult and one paediatric participant between 5 and 17 years of age were eligible to participate. Consented participants completed a survey on social determinants of health and were tested for antibodies using Abbott Architect SARS-CoV-2-IgG and SARS-CoV-2-IgM tests. PRIMARY OUTCOME MEASURE: Seropositive status. RESULTS: We analysed 390 adults (mean age in years, 38.98 (SD 12.11)) and 332 paediatric participants (11.26 (SD 3.51)) from 196 households. Estimated seropositivity was 52.11% (95% CI 49.61% to 55.19%) in paediatric participants and 63.58% (95% CI 60.39% to 65.24%) in adults. Seropositivity was 11.47% (95% CI 6.82% to 14.09%) lower in paediatric participants, but high relative to other populations. A household member with type 2 diabetes (OR 2.94 (95% CI 1.68 to 5.14)), receipt of food stamps (OR 1.66 (95% CI 1.08 to 2.56)) and lower head-of-household education (OR 1.73 (95% CI 1.06 to 2.84)) were associated with paediatric seropositivity. CONCLUSIONS: SARS-CoV-2 seropositivity is high in Hispanic children and adolescents in Los Angeles. Food insecure households with low head-of-household education, and at least one household member with type 2 diabetes, had the highest risk. These factors may inform paediatrician COVID-19 mitigation recommendations. TRIAL REGISTRATION NUMBER: NCT04901624.

Importance: Interventions that improve clinician performance through feedback should not contribute to job dissatisfaction or staff turnover. Measurement of job satisfaction may help identify interventions that lead to this undesirable consequence. Objective: To evaluate whether mean job satisfaction was less than the margin of clinical significance among clinicians who received social norm feedback (peer comparison) compared with clinicians who did not. Design, Setting, and Participants: This secondary, preregistered, noninferiority analysis of a cluster randomized trial compared 3 interventions to reduce inappropriate antibiotic prescribing in a 2 × 2 × 2 factorial design from November 1, 2011, to April 1, 2014. A total of 248 clinicians were enrolled from 47 clinics. The sample size for this analysis was determined by the number of nonmissing job satisfaction scores from the original enrolled sample, which was 201 clinicians from 43 clinics. Data analysis was performed from October 12 to April 13, 2022. Interventions: Feedback comparing individual clinician performance to top-performing peers, delivered in monthly emails (peer comparison). Main Outcomes and Measures: The primary outcome was a response to the following statement: "Overall, I am satisfied with my current job." Responses ranged from 1 (strongly disagree) to 5 (strongly agree). Results: A total of 201 clinicians (response rate, 81%) from 43 of the 47 clinics (91%) provided a survey response about job satisfaction. Clinicians were primarily female (n = 129 [64%]) and board certified in internal medicine (n = 126 [63%]), with a mean (SD) age of 48 (10) years. The clinic-clustered difference in mean job satisfaction was greater than -0.32 (ß = 0.11; 95% CI, -0.19 to 0.42; P = .46). Therefore, the preregistered null hypothesis that peer comparison is inferior by resulting in at least a 1-point decrease in job satisfaction by 1 in 3 clinicians was rejected. The secondary null hypothesis that job satisfaction was similar among clinicians randomized to social norm feedback was not able to be rejected. The effect size did not change when controlling for other trial interventions (t = 0.08; P = .94), and no interaction effects were observed. Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, peer comparison did not lead to lower job satisfaction. Features that may have protected against dissatisfaction include clinicians' agency over the performance measure, privacy of individual performance, and allowing all clinicians to achieve top performance. Trial Registration: ClinicalTrials.gov Identifiers: NCT05575115 and NCT01454947.

We aimed to determine if not using residual neuromuscular blockade (RNB) analysis to guide neuromuscular blockade reversal administration in the postsurgical ICU resulted in consequences related to residual weakness. This single-center, prospective study evaluated 104 patients arriving in a postcardiac surgical ICU. After demonstrating spontaneous movement and T > 35.5 °C, all patients underwent RNB evaluation, and neostigmine/glycopyrrolate was then administered. When patients later demonstrated an adequate Rapid Shallow Breathing Index, negative inspiratory force generation, and arterial blood gas values with minimal mechanical ventilatory support, RNB evaluation was repeated in 94 of the 104 patients, and all patients were extubated. Though RNB evaluation was performed, patients were extubated without considering these results. Eleven of one hundred four patients had not achieved a Train-of-Four (TOF) count of four prior to receiving neostigmine. Twenty of ninety-four patients demonstrated a TOF ratio ≤ 90% prior to extubation. Three patients received unplanned postextubation adjunct respiratory support-one for obvious respiratory weakness, one for pain-related splinting compounding baseline disordered breathing but without obvious benefit from BiPAP, and one for a new issue requiring surgery. Residual neuromuscular weakness may have been unrecognized before extubation in 1 of 104 patients administered neostigmine without RNB analysis. ICU-level care may mitigate consequences in such cases.
RESUMEN
PREMISE OF THE STUDY: Leaf area is a key trait that links plant form, function, and environment. Measures of leaf area can be biased because leaf area is often estimated from dried or fossilized specimens that have shrunk by an unknown amount. We tested the common assumption that this shrinkage is negligible. METHODS: We measured shrinkage by comparing dry and fresh leaf area in 3401 leaves of 380 temperate and tropical species and used phylogenetic and trait-based approaches to determine predictors of this shrinkage. We also tested the effects of rehydration and simulated fossilization on shrinkage in four species. KEY RESULTS: We found that dried leaves shrink in area by an average of 22% and a maximum of 82%. Shrinkage in dried leaves can be predicted by multiple morphological traits with a standard deviation of 7.8%. We also found that mud burial, a proxy for compression fossilization, caused negligible shrinkage, and that rehydration, a potential treatment of dried herbarium specimens, eliminated shrinkage. CONCLUSIONS: Our findings indicate that the amount of shrinkage is driven by variation in leaf area, leaf thickness, evergreenness, and woodiness and can be reversed by rehydration. The amount of shrinkage may also be a useful trait related to ecologically and physiological differences in drought tolerance and plant life history.

We investigated via a survey the relationship between hand clasping, arm folding, and handedness. We aimed to provide new data on degree of preference for each of these lateralities. We also examined the relative importance of thumb position versus interdigitisation of the fingers in determining one's comfort in a hand-clasping position. We explored this in the context of the fact that sensory acuity is greater for the thumb than other fingers, suggesting that preference for how the fingers are intermeshed may be more influenced by thumb than finger position. Lastly we performed an exploratory analysis to determine if self-reported menstrual phase-known to influence turning bias-also influences hand clasping, arm folding or the strength of one's handedness. Our study suggests that lateral preferences for hand clasping, arm folding, and handedness are independent. However, the degrees of lateral preference for hand clasping and arm folding are correlated. Our exploration of the relative importance of thumbs versus fingers to hand clasping revealed some trends that were not statistically significant, but worth future exploration. Our data on menstrual phase showed a reduced strength of preference for arm folding in mid-luteal females versus non-mid-luteal females.
