Equitable Care for Hypertension: Blood Pressure and Patient-Reported Outcomes of the RICH LIFE Cluster Randomized Trial.

BACKGROUND: Disparities in hypertension control are well documented but underaddressed. METHODS: RICH LIFE (Reducing Inequities in Care of Hypertension: Lifestyle Improvement for Everyone) was a 2-arm, cluster randomized trial comparing the effect on blood pressure (BP) control (systolic BP ≤140 mm Hg, diastolic BP ≤90 mm Hg), patient activation, and disparities in BP control of 2 multilevel interventions, standard of care plus (SCP) and collaborative care/stepped care (CC/SC). SCP included BP measurement standardization, audit and feedback, and equity-leadership training. CC/SC added roles to address social or medical needs. Primary outcomes were BP control and patient activation at 12 months. Generalized estimating equations and mixed-effects regression models with fixed effects of time, intervention, and their interaction compared change in outcomes at 12 months from baseline. RESULTS: A total of 1820 adults with uncontrolled BP and ≥1 other risk factors enrolled in the study. Their mean age was 60.3 years, and baseline BP was 152.3/85.5 mm Hg; 59.4% were women; 57.4% were Black, 33.2% were White, and 9.4% were Hispanic; 74% had hyperlipidemia; and 45.1% had type 2 diabetes. CC/SC did not improve BP control rates more than SCP. Both groups achieved statistically and clinically significant BP control rates at 12 months (CC/SC: 57.3% [95% CI, 52.7%-62.0%]; SCP: 56.7% [95% CI, 51.9%-61.5%]). Pairwise comparisons between racial and ethnic groups showed overall no significant differences in BP control at 12 months. Patients with coronary heart disease showed greater achievement of BP control in CC/SC than in SCP (64.0% [95% CI, 54.1%-73.9%] versus 50.8% [95% CI, 42.6%-59.0%]; P=0.04), as did patients in rural areas (67.3% [95% CI, 49.8%-84.8%] versus 47.8% [95% CI, 32.4%-63.2%]; P=0.01). Individuals in both arms experienced statistically and clinically significant reductions in mean systolic BP (CC/SC: -13.8 mm Hg [95% CI, -15.2 to -12.5]; SCP: -14.6 mm Hg [95% CI, -15.9 to -13.2]) and diastolic BP (CC/SC: -6.9 mm Hg [95% CI, -7.8 to -6.1]; SCP: -5.5 mm Hg [95% CI, -6.4 to -4.6]) over time. The difference in diastolic BP reduction between CC/SC and SCP over time was statistically significant (-1.4 mm Hg [95% CI, -2.6 to -0.2). Patient activation did not differ between arms. CC/SC showed greater improvements in patient ratings of chronic illness care (Patient Assessment of Chronic Illness Care score) over 12 months (0.12 [95% CI, 0.02-0.22]). CONCLUSIONS: Adding a collaborative care team to enhanced standard of care did not improve BP control but did improve patient ratings of chronic illness care.

Analyzing the role of ACE2, AR, MX1 and TMPRSS2 genetic markers for COVID-19 severity.

BACKGROUND: The use of molecular biomarkers for COVID-19 remains unconclusive. The application of a molecular biomarker in combination with clinical ones that could help classifying aggressive patients in first steps of the disease could help clinician and sanitary system a better management of the disease. Here we characterize the role of ACE2, AR, MX1, ERG, ETV5 and TMPRSS2 for trying a better classification of COVID-19 through knowledge of the disease mechanisms. METHODS: A total of 329 blood samples were genotyped in ACE2, MX1 and TMPRSS2. RNA analyses were also performed from 258 available samples using quantitative polymerase chain reaction for genes: ERG, ETV5, AR, MX1, ACE2, and TMPRSS2. Moreover, in silico analysis variant effect predictor, ClinVar, IPA, DAVID, GTEx, STRING and miRDB database was also performed. Clinical and demographic data were recruited from all participants following WHO classification criteria. RESULTS: We confirm the use of ferritin (p < 0.001), D-dimer (p < 0.010), CRP (p < 0.001) and LDH (p < 0.001) as markers for distinguishing mild and severe cohorts. Expression studies showed that MX1 and AR are significantly higher expressed in mild vs severe patients (p < 0.05). ACE2 and TMPRSS2 are involved in the same molecular process of membrane fusion (p = 4.4 × 10-3), acting as proteases (p = 0.047). CONCLUSIONS: In addition to the key role of TMPSRSS2, we reported for the first time that higher expression levels of AR are related with a decreased risk of severe COVID-19 disease in females. Moreover, functional analysis demonstrates that ACE2, MX1 and TMPRSS2 are relevant markers in this disease.

Cuidándome: A trauma-informed and cultural adaptation of a chronic disease self-management program for Latina immigrant survivors with a history of adverse childhood experiences and depression or anxiety symptoms.

OBJECTIVES: To develop a cultural and trauma-informed mental health self-management program for immigrant Latina survivors of adverse childhood experiences with depression or anxiety symptoms. METHOD: Guided by Barrera's five-stage process for cultural adaptation, we collaborated with multiple stakeholders including clinical psychologists, community health workers, and Latina immigrant women with a history of adverse childhood experiences and depression or anxiety to transform a chronic disease self-management program to be trauma informed, culturally appropriate, and focus on self-management of depression and anxiety symptoms. RESULTS: Adaptations included translating program materials to Spanish, education on how early life adversity and trauma may impact mental health, virtual delivery, more frequent and shorter sessions, and addition of graphics and written prompts in workbook materials. For the facilitator's manual, culturally relevant vignettes and guidance were added to guide participants through activities and adapt sessions based on participant needs. CONCLUSIONS: Barrera's five-stage process was useful for adapting a program to be both trauma and culturally informed for an underserved population disproportionately affected by trauma and limited access to mental health services. The adaptation demonstrated acceptability with Latina immigrant women and the promise of utilizing unlicensed personnel and technology for increasing the reach of mental health support.

The growth-immunity tradeoff in Brassica oleracea-Xanthomonas campestris pv. campestris pathosystem.

Plant responses against pathogens are influenced by growth immunity tradeoff, which ensure the best use of limited resources. We study how the immobilization of carbon resources and the induction of defensive responses (glucosinolates, phenolic compounds, stomatal closure) can influence the biomass of two Brassica oleracea lines, differing in their resistance, after infection with Xanthomonas campestris pv. campestris. Potentially, the growth immunity tradeoff can be influenced by the activation of all these processes. However, on the contrary of which is normally stated, our results suggest that the loss of biomass caused by pathogen infection is mainly due to the differential accumulation of starch and the immobilization of sugars rather than the reallocation of resources to synthesize secondary metabolites. Moreover, resistance may be related to the effectiveness of the tradeoff, since the resistant line immobilizes resources more efficiently than the susceptible one. Both inbred lines show a different phytohormones profile, which support the hypothesis that they are employing different strategies to defend themselves against the pathogen. This study emphasizes the key role of the primary metabolism in the defence strategies of plants against pathogens.

Susceptibility to hepatitis B virus infection in adults living in Spain.

BACKGROUND: A protective hepatitis B virus (HBV) vaccine has been available for four decades. Universal HBV vaccination of infants is recommended by the WHO since the 1990s. Furthermore, HBV immunization is advised for all adults with high-risk behaviours and no seroprotection. However, HBV vaccine coverage remains globally suboptimal. The advent of new more efficacious trivalent HBV vaccines has renewed the interest in HBV vaccination. At present, the extent of current HBV susceptibility in adults remains unknown in Spain. METHODS: HBV serological markers were assessed on a large and representative sample of adults in Spain, including blood donors and individuals belonging to high-risk groups. Serum HBsAg, anti-HBc and anti-HBs were tested in specimens collected during the last couple of years. RESULTS: From 13 859 consecutive adults tested at seven cities across the Spanish geography, overall 166 (1.2%) had positive HBsAg. Past HBV infection was recognized in 14% and prior vaccine immunization in 24%. Unexpectedly, 37% of blood donors and 63% of persons belonging to high-risk groups had no serum HBV markers and therefore were potentially HBV susceptible. CONCLUSION: Roughly 60% of adults living in Spain seem to be HBV susceptible. Waning immunity might be more common than expected. Hence, HBV serological testing should be performed at least once in all adults regardless of risk exposures. HBV vaccine full courses or boosters should be administered to all adults lacking serological evidence of HBV protection.

Tubulointerstitial nephritis and uveitis syndrome and SARS-CoV-2 infection in an adolescent: just a coincidence in time?

BACKGROUND: Despite recent well-established kidney tropism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), usually presenting as acute kidney injury (AKI), there are few published cases with SARS-CoV-2-related tubulointerstitial nephritis (TIN). We report an adolescent with TIN and delayed association with uveitis (TINU syndrome), where SARS-CoV-2 spike protein was identified in kidney biopsy. CASE-DIAGNOSIS/TREATMENT: A 12-year-old girl was assessed for a mild elevation of serum creatinine detected during the evaluation of systemic manifestations including asthenia, anorexia, abdominal pain, vomiting, and weight loss. Data of incomplete proximal tubular dysfunction (hypophosphatemia and hypouricemia with inappropriate urinary losses, low molecular weight proteinuria, and glucosuria) were also associated. Symptoms had initiated after a febrile respiratory infection with no known infectious cause. After 8 weeks, the patient tested positive in PCR for SARS-CoV-2 (Omicron variant). A subsequent percutaneous kidney biopsy revealed TIN and immunofluorescence staining with confocal microscopy detected the presence of SARS-CoV-2 protein S within the kidney interstitium. Steroid therapy was started with gradual tapering. Ten months after onset of clinical manifestations, as serum creatinine remained slightly elevated and kidney ultrasound showed mild bilateral parenchymal cortical thinning, a second percutaneous kidney biopsy was performed, without demonstrating acute inflammation or chronic changes, but SARS-CoV-2 protein S within the kidney tissue was again detected. At that moment, simultaneous routine ophthalmological examination revealed an asymptomatic bilateral anterior uveitis. CONCLUSIONS: We present a patient who was found to have SARS-CoV-2 in kidney tissue several weeks following onset of TINU syndrome. Although simultaneous infection by SARS-CoV-2 could not be demonstrated at onset of symptoms, since no other etiological cause was identified, we hypothesize that SARS-CoV-2 might have been involved in triggering the patient's illness.

Theoretical study of Gibbs free energy and NMR chemical shifts, of the effect of methyl substituents on the isomers of (E)-1-(α,Ꞵ-Dimethylbenzyliden)-2,2-diphenylhydrazine.

A theoretical analysis of free Gibbs Energy and NMR 1H 13C chemical shifts of the effect of introduce methyl groups on diphenyl rings, to produce different isomers of (E)-1-(α,Ꞵ-dimethylbenzylidene)-2,2-diphenylhydrazine, is presented. IR vibrational frequencies, Mulliken charges, molecular electrostatic potential (MEP), Gibbs free energy (G) and 1H- and 13C-NMR chemical shifts were obtained by theoretical calculations. In this analysis it was found that the position of the methyl group affects the values of the 1H- and 13C-NMR chemical shifts and the ∆G and ∆H thermodynamic properties of formation and reaction, these properties vary with the same trend, for the isomers studied. Gibbs free energy calculations show that the theoretical (E)-1-(3,4-Dimethylbenzylidene)-2,2-diphenylhydrazine isomer is the most stable, which explains the success of the experimental synthesis of this compound among the other isomers. For this molecule, the C of the HC=N group is the most nucleophilic and the H is the least acidic. The 1H-NMR chemical shifts of protons show a strong correlation with the C=N distance. It was also observed that methyl affects the ν(C=N) frequencies, the C=N distance increases when the inductive effect of the methyl groups is in the structure.

Puerto Rican healthcare workers' perspectives on the impact of COVID-19 pandemic on their role, patient care, and mental health.

PURPOSE: To explore the personal and work-related stressors of healthcare workers in Puerto Rico and the organizational support they received during the pandemic. DESIGN AND METHODS: We used a qualitative descriptive design and from April - November, 2021, conducted semi-structured individual interviews with Puerto Rican frontline healthcare workers (n = 12) and supervisors (n = 5). FINDINGS: Thematic analysis revealed five major themes: (a) Organizations' response to COVID-19; (b) increased complexity of patients; (c) intensified work and psychological demand for nurses; (d) overwhelmed and overworked; and (e) recommendations for healthcare leadership. Participants explained that their organizations' responses to COVID-19 were insufficient for  meeting the demands and acuity of the patients. Closure of outpatient services contributed to people presenting to hospitals with exacerbated chronic conditions - especially the elderly. With COVID-19 precautions prohibiting family visitation, nurses became responsible for total care, including emotional support of patients. In addition, the shortage of staff contributed to nurses assuming greater workloads, feeling overwhelmed and overworked, and healthcare worker resignations. Given their experiences, healthcare workers recommended that healthcare leadership show more appreciation for staff, demonstrate empathy, include frontline workers in decision-making, and provide mental health resources for staff. CONCLUSIONS: This study with Puerto Rican frontline workers and supervisors uncovers the multiple stressors experienced during the COVID-19 pandemic. Our findings underscore the need for prioritizing the well-being of healthcare workers, preparing healthcare leadership on how to support staff, and mandating nurse-to-patient ratios. CLINICAL RELEVANCE: Healthcare workers explained the barriers they experienced for providing quality care to their patients. They also presented recommendations for healthcare leadership to facilitate supporting frontline workers, which ultimately contributes to optimal patient care.

Active legs: Impact of physical activity as an adjuvant treatment in the healing of venous ulcers in primary care: a RCT protocol study.

BACKGROUND: Venous ulcers usually present a torpid evolution with a negative impact on patients' quality of life. In primary care, they account for 2.5% of nursing consultations and their treatment represents high costs for national health systems. These patients usually have a low level of physical activity, with muscle pump dysfunction of the lower limbs, which may improve with increased physical activity. The purpose of this study is to analyse the effectiveness of a structured intervention involving physical activity and exercise (Active Legs) as an adjuvant treatment in improving healing of chronic venous ulcers at 3 months follow-up. METHODS: A randomized, multicentre clinical trial. A total of 224 individuals receiving primary nursing care with a diagnosis of venous ulcer, with a diameter of 1 cm or greater and an ankle-brachial index between 0.8 and 1.3, able to comply with the study requirements and consenting to participate, will be sequentially included (112 per group). Both groups will receive the standard treatment in primary care, with cleansing, debridement and healing in a moist environment together with multilayer compression therapy. The intervention group will also receive a structured educational intervention involving lower limb physical exercise and daily ambulation guidelines. The primary response variables will be complete healing -understood as complete and sustained epithelialisation for at least 2 weeks- and time to healing. The secondary variables will be degree of healing, ulcer area, quality of life, pain and variables related to the healing process, prognosis, and recurrences. Sociodemographic variables, adherence to treatment and satisfaction variables will also be recorded. Data will be collected at baseline, at 3 months and at 6 months follow-up. Survival analysis (Kaplan-Meier and Cox) will be performed to measure primary effectiveness. Intention-to-treat analysis. DISCUSSION: If the intervention is effective, a cost-effectiveness analysis could be conducted and implemented as an additional intervention in the usual venous ulcer treatment in primary care. TRIAL REGISTRATION: NCT04039789. [ https://ClinicalTrials.gov ]. 07/11/2019.

Ozonated oil is effective at killing Candida species and Streptococcus mutans biofilm-derived cells under aerobic and microaerobic conditions.

This study explores the growth of bacterial, fungal, and interkingdom biofilms under aerobiosis or microaerobic conditions and the effect of ozonated sunflower oil on these biofilms. Candida species and Streptococcus mutans were used to study this interaction due to their importance in oral health and disease as these microorganisms display a synergistic relationship that manifests in the onset of caries and tooth decay. Biofilms were developed in a 96-well microtiter plate at 37ºC for 24 h, under aerobiosis or microaerobic conditions, and treated with ozonated oil for 5 to 120 min. All the microorganisms formed biofilms in both oxygenation conditions. Scanning electron microscopy was used to visualize biofilm morphology. Rodent experiments were performed to verify the oil-related toxicity and its efficacy in oral candidiasis. The growth of all Candida species was increased when co-cultured with S. mutans, whilst the growth of bacterium was greater only when co-cultured with C. krusei and C. orthopsilosis under aerobiosis and microaerobic conditions, respectively. Regardless of the oxygenation condition, ozonated oil significantly reduced the viability of all the tested biofilms and infected mice, showing remarkable microbicidal activity as corroborated with confocal microscopy and minimal toxicity. Thus, ozonated oil therapy can be explored as a strategy to control diseases associated with these biofilms especially in the oral cavity. LAY SUMMARY: We demonstrated that ozonated sunflower oil is effective at killing the biofilms formed by Candida species, by the bacterium Streptococcus mutans, or by both micoorganisms that can interact in the oral cavity, making it a potential therapeutic option for the treatment of these infections.

Perinatal undernourishment provokes long-lasting alterations of clusterin and fumarate hydratase expression in the rat nucleus accumbens.

BACKGROUND: Background: Perinatal malnutrition seems to provoke important neurochemical alterations in the brain that lead to higher vulnerability to develop neuropsychiatric disorders in the adulthood. OBJECTIVES: We have examined the persistence and reversibility of the changes induced by perinatal undernourishment on the expression of fumarate hydratase in the rat nucleus accumbens, bearing in mind that this expression has been previously linked with addictive disorders. Clusterin, a multifunctional protein known to be neuroprotective and possibly related to addiction in humans, was studied in parallel. METHODS: Female Wistar rats underwent a severe restriction of food during gestation and lactation. Upon weaning, a subgroup of undernourished animals was switched to normal chow and another one continued under food restriction. Control rats and their mothers were fed on chow along the experiment. Fumarate hydratase and clusterin were quantified by western blot after five months of postnatal life in the three experimental groups. RESULTS: Food restriction along the whole experimental period provoked a marked upregulation of both clusterin and fumarate hydratase in the mitochondrial fraction of the nucleus accumbens. In the case of clusterin, this upregulation was also observed in the cytosolic fraction of the nucleus accumbens. When undernourishment was limited to gestation and lactation the two proteins appeared downregulated with respect to controls. CONCLUSION: The results are consistent with the idea that perinatal malnutrition provokes marked changes in brain neurochemistry that are not fully corrected by the rehabilitation of normal feeding and could be linked to behavioural disturbances in the adulthood, that is, increased vulnerability to addiction.

The RICH LIFE Project: A cluster randomized pragmatic trial comparing the effectiveness of health system only vs. health system Plus a collaborative/stepped care intervention to reduce hypertension disparities.

Disparities in the control of hypertension and other cardiovascular disease risk factors are well-documented in the United States, even among patients seen regularly in the healthcare system. Few existing approaches explicitly address disparities in hypertension care and control. This paper describes the RICH LIFE Project (Reducing Inequities in Care of Hypertension: Lifestyle Improvement for Everyone) design. METHODS: RICH LIFE is a two-arm, cluster-randomized trial, comparing the effectiveness of enhanced standard of care, "Standard of Care Plus" (SCP), to a multi-level intervention, "Collaborative Care/Stepped Care" (CC/SC), for improving blood pressure (BP) control and patient activation and reducing disparities in BP control among 1890 adults with uncontrolled hypertension and at least one other cardiovascular disease risk factor treated at 30 primary care practices in Maryland and Pennsylvania. Fifteen practices randomized to the SCP arm receive standardized BP measurement training; race/ethnicity-specific audit and feedback of BP control rates; and quarterly webinars in management practices, quality improvement and disparities reduction. Fifteen practices in the CC/SC arm receive the SCP interventions plus implementation of the collaborative care model with stepped-care components (community health worker referrals and virtual specialist-panel consults). The primary clinical outcome is BP control (<140/90 mm Hg) at 12 months. The primary patient-reported outcome is change from baseline in self-reported patient activation at 12 months. DISCUSSION: This study will provide knowledge about the feasibility of leveraging existing resources in routine primary care and potential benefits of adding supportive community-facing roles to improve hypertension care and reduce disparities.

[Effectiveness of double-layered compression therapy against crepe bandage for healing venous ulcers in primary care. Randomized clinical trial]. / Efectividad de la terapia compresiva de doble capa frente al vendaje de crepé en la cicatrización de úlceras venosas en atención primaria. Ensayo clínico aleatorizado.

OBJECTIVE: To evaluate if the two-layer bandage is more effective than the crepe bandage in the healing of venous ulcers after 12 weeks of follow-up. DESIGN: Randomized multicentre controlled clinical trial. LOCATION: 22 Primary Health Centers of Madrid. PARTICIPANTS: Over 18 years old, with diagnosis of venous ulcers. 93 patients were randomized, 56 in the double layer group and 37 in the crepe group. Withdrawals: 16 in double layer group, 7 in crepe group. INTERVENTIONS: Control group: usual clinical practice: treatment of the wound and bandage with crepe. Experimental group: same usual clinical practice for wound treatment and bandage with double layer. MAIN MEASUREMENTS: Primary outcome: complete healing at 12 weeks. SECONDARY OUTCOMES: severity of ulceration, health-related quality of life, adverse events. Blind evaluation of the response variable. RESULTS: Complete healing: in crepe group, 25, 67.5% (95% CI 50.2-81.9) and in double layer group, 32, 57.1% (95% CI 43.2-70.3). No evidence of a difference in both groups, RR=1.10 (95% CI 0.864-1.424). The basal severity of the ulcers is associated with the healing time. HR=0.86 (95% CI 0.78-0.94). Our data showed a significant improvement in health-related quality of life, total and in the of cosmesis and emotional dimensions. No evidence of a difference in both groups. We didn't find serious adverse events in any of the groups. CONCLUSIONS: We didn't find significant differences in the healing between the two bandages evaluated. Both are appropriate for ulcer healing and to improve the health-related quality of life.

A novel glucagon-like peptide 1/glucagon receptor dual agonist improves steatohepatitis and liver regeneration in mice.

Because nonalcoholic steatohepatitis (NASH) is associated with impaired liver regeneration, we investigated the effects of G49, a dual glucagon-like peptide-1/glucagon receptor agonist, on NASH and hepatic regeneration. C57Bl/6 mice fed chow or a methionine and choline-deficient (MCD) diet for 1 week were divided into 4 groups: control (chow diet), MCD diet, chow diet plus G49, and M+G49 (MCD diet plus G49). Mice fed a high-fat diet (HFD) for 10 weeks were divided into groups: HFD and H+G49 (HFD plus G49). Following 2 (MCD groups) or 3 (HFD groups) weeks of treatment with G49, partial hepatectomy (PH) was performed, and all mice were maintained on the same treatment schedule for 2 additional weeks. Analysis of liver function, hepatic regeneration, and comprehensive genomic and metabolic profiling were conducted. NASH was ameliorated in the M+G49 group, manifested by reduced inflammation, steatosis, oxidative stress, and apoptosis and increased mitochondrial biogenesis. G49 treatment was also associated with replenishment of intrahepatic glucose due to enhanced gluconeogenesis and reduced glucose use through the pentose phosphate cycle and oxidative metabolism. Following PH, G49 treatment increased survival, restored the cytokine-mediated priming phase, and enhanced the proliferative capacity and hepatic regeneration ratio in mice on the MCD diet. NASH markers remained decreased in M+G49 mice after PH, and glucose use was shifted to the pentose phosphate cycle and oxidative metabolism. G49 administered immediately after PH was also effective at alleviating the pathological changes induced by the MCD diet. Benefits in terms of liver regeneration were also found in mice fed HFD and treated with G49. CONCLUSION: Dual-acting glucagon-like peptide-1/glucagon receptor agonists such as G49 represent a novel therapeutic approach for patients with NASH and particularly those requiring PH.

An increase in estradiol facilitates the onset of paternal behavior in the dwarf hamster (Phodopus campbelli).

In the dwarf hamster (Phodopus campbelli), activational effects of testosterone (T) and estradiol (E2) in the regulation of paternal behavior have been repeatedly rejected because peripheral concentrations of E2 do not change across the reproductive cycle of males. Further, castration no affected paternal behavior despite that both T and E2 concentrations decreased significantly. However, the role of these hormones has not been evaluated in models of castration and hormonal replacement in virgin males. Here, we analysed the effects of E2 and T in paternal behavior in virgin male dwarf hamster (Phodopus campbelli). Thirty paternal (PAT) males were bilaterally castrated; of them, 10 were implanted with T, 10 with E2 and 10 males received no treatment. Other 10 PAT males underwent sham-castration. Seventeen aggressive (AGG) males were also bilaterally castrated; of these, 10 AGG received E2 replacement, 7 were not treated. Other 7 AGG males were submitted to sham-castration. Following treatments, paternal behavior tests were conducted again. T and E2 levels in plasma were quantified by radioimmunoassay (RIA). The results showed that the treatments did not affect the paternal behavior of males that were initially paternal. Neither castration nor sham-castration surgery affected the behavior of AGG males. However, when these males were treated with E2 and the concentrations of this hormone increase significantly they became paternal. Our data suggest that an increase in E2 levels shifted infanticidal behavior to paternal behavior in dwarf hamster.

Responding to intimate partner violence: Healthcare providers' current practices and views on integrating a safety decision aid into primary care settings.

Supportive care for survivors of intimate partner violence (IPV) remains limited in primary care settings. Low-income and Spanish-speaking survivors of IPV are even more disadvantaged, given the dearth of linguistically and culturally appropriate interventions for IPV. We conducted semi-structured individual interviews with 17 healthcare workers, including physicians, nurses, and social workers, to describe how healthcare workers serving primarily low-income, Latina populations are currently screening and responding to IPV disclosure, and to explore the acceptability of integrating an interactive, personalized safety decision aid application-myPlan app-into the clinic setting. Despite recognition of IPV as a problem, none of the clinical sites had a protocol to guide screening and response to IPV disclosure. Screening practices varied across the sites, sometimes conducted by medical assistants prior to the provider visit and other times by the physician or nurse provider. When IPV was disclosed, it was often during assessment for a presenting problem such as poor sleep or anxiety. Most healthcare workers felt that clinical and community resources were limited for their patients experiencing IPV. The "warm hand-off" to a social worker was the most common response strategy when possible; otherwise, women were given information about available resources such as hotlines and safe houses. We discuss structural, family, and individual barriers to accessing safety resources for underserved women and review how an easily accessible safety decision app, such as myPlan, could be a resource for women to safely tailor an action plan for her situation.

Activation of Wnt Signaling in Cortical Neurons Enhances Glucose Utilization through Glycolysis.

The Wnt signaling pathway is critical for a number of functions in the central nervous system, including regulation of the synaptic cleft structure and neuroprotection against injury. Deregulation of Wnt signaling has been associated with several brain pathologies, including Alzheimer's disease. In recent years, it has been suggested that the Wnt pathway might act as a central integrator of metabolic signals from peripheral organs to the brain, which would represent a new role for Wnt signaling in cell metabolism. Energy metabolism is critical for normal neuronal function, which mainly depends on glucose utilization. Brain energy metabolism is important in almost all neurological disorders, to which a decrease in the capacity of the brain to utilize glucose has been linked. However, little is known about the relationship between Wnt signaling and neuronal glucose metabolism in the cellular context. In the present study, we found that acute treatment with the Wnt3a ligand induced a large increase in glucose uptake, without changes in the expression or localization of glucose transporter type 3. In addition, we observed that Wnt3a treatment increased the activation of the metabolic sensor Akt. Moreover, we observed an increase in the activity of hexokinase and in the glycolytic rate, and both processes were dependent on activation of the Akt pathway. Furthermore, we did not observe changes in the activity of glucose-6-phosphate dehydrogenase or in the pentose phosphate pathway. The effect of Wnt3a was independent of both the transcription of Wnt target genes and synaptic effects of Wnt3a. Together, our results suggest that Wnt signaling stimulates glucose utilization in cortical neurons through glycolysis to satisfy the high energy demand of these cells.
