RESUMO

Astrocytes are multi-functional glial cells in the central nervous system that play critical roles in modulation of metabolism, extracellular ion and neurotransmitter levels, and synaptic plasticity. Astrocyte-derived signaling molecules mediate many of these modulatory functions of astrocytes, including vesicular release of ATP. In the present study, we used a unique genetic mouse model to investigate the functional significance of astrocytic exocytosis of ATP. Using primary cultured astrocytes, we show that loss of vesicular nucleotide transporter (Vnut), a primary transporter responsible for loading cytosolic ATP into the secretory vesicles, dramatically reduces ATP loading into secretory lysosomes and ATP release, without any change in the molecular machinery of exocytosis or total intracellular ATP content. Deletion of astrocytic Vnut in adult mice leads to increased anxiety, depressive-like behaviors, and decreased motivation for reward, especially in females, without significant impact on food intake, systemic glucose metabolism, cognition, or sociability. These behavioral alterations are associated with significant decreases in the basal extracellular dopamine levels in the nucleus accumbens. Likewise, ex vivo brain slices from these mice show a strong trend toward a reduction in evoked dopamine release in the nucleus accumbens. Mechanistically, the reduced dopamine signaling we observed is likely due to an increased expression of monoamine oxidases. Together, these data demonstrate a key modulatory role of astrocytic exocytosis of ATP in anxiety, depressive-like behavior, and motivation for reward, by regulating the mesolimbic dopamine circuitry.

RESUMO

Objectives. To examine the accessibility of hospital facilities with maternity care services in 1 rural county in Alabama in preparation for the initiation of prenatal care services at a federally qualified health center. Methods. We analyzed driving distance (in miles) from maternal city of residence in Conecuh County, Alabama to hospital of delivery, using 2019-2021 vital statistics data and geographic information system (GIS) software. Results. A total of 370 births to mothers who have home addresses in Conecuh County were reported, and 368 of those were in hospital facilities. The majority of deliveries were less than 30 miles (median = 23 miles) from the maternal city of residence. Some women traveled more than 70 miles for obstetrical care. Conclusions. Pregnant patients in Conecuh County experience significant geographic barriers related to perinatal care access. Using GIS for this analysis is a promising approach to better understand the unique challenges of pregnant individuals in this rural population. Public health policy efforts need to be geographically tailored to address these disparities. (Am J Public Health. 2024;114(S4):S330-S333. https://doi.org/10.2105/AJPH.2024.307692).

RESUMO

INTRODUCTION: Patients with uncontrolled diabetes living in rural communities experience many challenges, including lack of access to needed medication management services. Telepharmacy has been identified as a promising approach for addressing this gap. This presentation describes early insights into the implementation of a Comprehensive Medication Management (CMM) service in seven rural primary care clinics in North Carolina and Arkansas (USA). The CMM service involved two pharmacists meeting remotely with patients in their homes to identify and resolve Medication Therapy Problems (MTPs). STUDY DESIGN: This exploratory mixed methods study uses a pre-post design. Data sources include surveys, qualitative interviews, administrative data, and medical records (eg MTPs, hemoglobin A1Cs) collected as part of the first 3 months of a 1-year implementation period. METHODS: Lessons learned were identified through qualitative interviews with six clinic liaisons, review of pharmacists' observations, and open-ended survey questions with clinic staff and providers. Early service effectiveness was informed by MTP resolution rates and changes in patients' A1C levels. RESULTS: Key insights centered on the perceived benefits of the service for patients and clinics, the importance of patient engagement, access to implementation strategies (eg workflows and technical assistance calls), and the need to adapt the CMM service and implementation strategies to local context. The MTP resolution rate averaged 88% across pharmacists. There was a significant decrease in A1Cs in participating patients as a result of the service. CONCLUSION: Although preliminary, these results support the value of a pharmacist-led medication optimization service through remote delivery for complex patients with uncontrolled diabetes.

RESUMO

Serologic point-of-care tests to detect antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are an important tool in the COVID-19 pandemic. The majority of current point-of-care antibody tests developed for SARS-CoV-2 rely on lateral flow assays, but these do not offer quantitative information. To address this, we developed a novel antibody test leveraging hemagglutination, employing a dry card format currently used for typing ABO blood groups. Two hundred COVID-19 patient and 200 control plasma samples were reconstituted with O-negative red blood cells (RBCs) to form whole blood and added to dried viral-antibody fusion protein, followed by a stirring step and a tilting step, 3-min incubation, and a second tilting step. The sensitivities of the hemagglutination test, Euroimmun IgG enzyme-linked immunosorbent assay (ELISA), and receptor binding domain (RBD)-based CoronaChek lateral flow assay were 87.0%, 86.5%, and 84.5%, respectively, using samples obtained from recovered COVID-19 individuals. Testing prepandemic samples, the hemagglutination test had a specificity of 95.5%, compared to 97.3% and 98.9% for the ELISA and CoronaChek, respectively. A distribution of agglutination strengths was observed in COVID-19 convalescent-phase plasma samples, with the highest agglutination score (4) exhibiting significantly higher neutralizing antibody titers than weak positives (2) (P < 0.0001). Strong agglutinations were observed within 1 min of testing, and this shorter assay time also increased specificity to 98.5%. In conclusion, we developed a novel rapid, point-of-care RBC agglutination test for the detection of SARS-CoV-2 antibodies that can yield semiquantitative information on neutralizing antibody titer in patients. The 5-min test may find use in determination of serostatus prior to vaccination, postvaccination surveillance, and travel screening.

RESUMO

Objectives: The objective of this study is to examine associations between adolescents' regulation of information about their type 1 diabetes (adolescent disclosure, secrecy), parental knowledge about their adolescent's diabetes management, diabetes outcomes (adherence, HbA1c), and depressive symptoms in Non-Latino White and Latino families. Methods: In all, 118 adolescents (56 = Latino, 62 = Non-Latino White) completed surveys of disclosure to and secrecy from parents, parental knowledge of adolescent diabetes management, adherence, and depressive symptoms, and mothers completed measures of maternal knowledge and adolescent adherence. Glycemic control was extracted from medical records. Adolescents also completed structured interviews about parental knowledge about their diabetes-related problems. Results: Interviews revealed that adolescent disclosure is the primary method by which parents gain knowledge about adolescent diabetes management problems. Adolescent disclosure to and secrecy from parents were uniquely associated with diabetes management and depressive symptoms independent of parental knowledge across ethnic groups; maternal reports of knowledge about her adolescent's diabetes care activities were associated with diabetes management independent of adolescent disclosure and secrecy. Conclusions: Adolescent information management strategies are a primary means by which parents gain knowledge about diabetes, which may facilitate more effective management.

RESUMO

BACKGROUND: Significant challenges exist within primary care services in the United Kingdom (UK). These include meeting current demand, financial pressures, an aging population and an increase in multi-morbidity. Psychological services also struggle to meet waiting time targets and to ensure increased access to psychological therapies. Innovative ways of delivering effective primary care and psychological services are needed to improve health outcomes. In this article we argue that integrated care models that incorporate behavioural health care are part of the solution, which has seldom been argued in relation to UK primary care. Integrated care involves structural and systemic changes to the delivery of services, including the co-location of multi-disciplinary primary care teams. Evidence from models of integrated primary care in the United States of America (USA) and other higher-income countries suggest that embedding continuity of care and collaborative practice within integrated care teams can be effective in improving health outcomes. The Behavioural Health Consultant (BHC) role is integral to this, working psychologically to support the team to improve collaborative working, and supporting patients to make changes to improve their health across management of long-term conditions, prevention and mental wellbeing. Patients' needs for higher-intensity interventions to enable changes in behaviour and self-management are, therefore, more fully met within primary care. The role also increases accessibility of psychological services, delivers earlier interventions and reduces stigma, since psychological staff are seen as part of the core primary care service. Although the UK has trialled a range of approaches to integrated care, these fall short of the highest level of integration. A single short pilot of integrated care in the UK showed positive results. Larger pilots with robust evaluation, as well as research trials are required. There are clearly challenges in adopting such an approach, especially for staff who must adapt to working more collaboratively with each other and patients. Strong leadership is needed to assist in this, particularly to support organisations to adopt the shift in values and attitudes towards collaborative working. CONCLUSIONS: Integrated primary care services that embed behavioural health as part of a multi-disciplinary team may be part of the solution to significant modern day health challenges. However, developing this model is unlikely to be straight-forward given current primary care structures and ways of working. The discussion, developed in this article, adds to our understanding of what the BHC role might consist off and how integrated care may be supported by such behavioural health expertise. Further work is needed to develop this model in the UK, and to evaluate its impact on health outcomes and health care utilisation, and test robustly through research trials.

RESUMO

ABSTRACT: The primary objective of this systematic review is to describe the effectiveness of nerve transfers for restoring quadriceps motor function in patients with femoral nerve palsy. MEDLINE, EMBASE and CENTRAL were searched from their inception to June 2023 for any English language, primary literature investigating nerve transfers for femoral nerve palsy. Data was extracted for study and intervention characteristics, and clinical outcomes, including preoperative and postoperative knee extension strength, electrodiagnostic studies, functional outcomes, adverse events and donor site morbidity. The primary outcome was defined as return of knee extension equivalent to or greater than a grade 4- on the Medical Research Council scale. Eighteen studies with a total of 40 patients were included. The most common nerve donor was the obturator nerve in 17 studies with 37 patients, followed by the nerve to sartorius in two studies (10 patients). Significant variations in procedures and outcomes reported were observed. There were no studies that reported an effect on ambulation due to donor weakness. Based on the available literature, nerve transfer appears to be an effective treatment for restoring quadriceps function in this population, with 79% of patients in our study achieving at minimum 4-/5 MRC grade power.

RESUMO

PURPOSE: The current study sought to determine if the release of COVID-19 vaccines influenced Alabama mothers' attitudes and behaviors regarding HPV vaccination of their adolescent children. METHODS: A social media survey was conducted August - September 2022 among mothers of adolescents ages 9-18, who self-identified as Alabama residents and their child(ren)'s primary medical decision maker. The survey assessed demographics, vaccine knowledge and opinions, vaccination history, influences on vaccination decisions, and how COVID-19 vaccine release affected vaccine opinions. Univariable and multivariable analyses were conducted. RESULTS: Of 241 responses, most participants were white (82.0 %, n = 196), non-Hispanic (96.6 %, n = 230), and privately insured (64.5 %, n = 151), with annual household incomes ≥$61,000 (45.4 %, n = 103). The majority (60.8 %) reported that their child either had or planned to receive the HPV vaccine. The release of COVID-19 vaccines did not change the majority of parental opinions towards HPV, with 78.5 % (n = 161) reporting no change. Among those who experienced a change, 25 % (n = 5) reported an increased likelihood of having their child vaccinated for HPV and 75 % (n = 15) reported a decrease in likelihood. Moderate and high HPV knowledge scores were associated in multivariable analysis with increased likelihood of having their child vaccinated for HPV ("moderate" knowledge AOR: 12.4, 95 % CI: 1.98-78.1; "high" knowledge AOR: 12.8, 95 % CI: 2.00-82.1). Positive HPV opinion scores in the univariable analysis similarly showed increased odds (AOR = 1.5). CONCLUSIONS: These findings indicate that, in this population, COVID-19 vaccine release did not significantly impact subsequent HPV vaccination decision making. Parental perceptions regarding vaccination are critical to informing future interventions.

RESUMO

Background: The advent of COVID-19 exacerbated the impact of social determinants of health (SDOH) on patients' ability to manage their health, especially those with chronic conditions. Clinical pharmacists are well positioned to expand the patient care services they already provide to address patients' basic social needs, which may otherwise impede medication access and adherence. Objectives: The purpose of this exploratory study was to evaluate the feasibility of expanding a comprehensive medication management (CMM) telepharmacy service to include SDOH support. This service was offered as part of four primary care clinics in rural and underserved North Carolina communities. More specifically, the study aimed to describe the expanded service, evaluate stakeholders' experience with the service, and assess short-term impact on patients with diabetes. Methods: Data collected over the first 4 months of implementation included administrative data used to describe the expanded service; a clinic survey and interviews to assess clinic team members' experience with the service; and patient surveys to evaluate patient satisfaction, as well as impact on SDOH self-efficacy and diabetes quality of life. Results: Through SDOH screening, the pharmacist identified 26 unresolved COVID-prompted SDOH concerns across 66 patients. These concerns were addressed by the pharmacist through three types of brief interventions, including information provision/education (71%), access to resources (21%), and additional care coordination (7%). Clinic team members perceived the expanded service as highly satisfactory and beneficial. Patients also reported high levels of satisfaction and significantly increased their SDOH self-efficacy and diabetes quality of life as a result of the service. Conclusion: These data provide preliminary insights into the expanded role that pharmacists can play to address current population health gaps that can directly impact patients' engagement with their medication regimen and overall health status.

RESUMO

Serologic, point-of-care tests to detect antibodies against SARS-CoV-2 are an important tool in the COVID-19 pandemic. The majority of current point-of-care antibody tests developed for SARS-CoV-2 rely on lateral flow assays, but these do not offer quantitative information. To address this, we developed a new method of COVID-19 antibody testing employing hemagglutination tested on a dry card, similar to that which is already available for rapid typing of ABO blood groups. A fusion protein linking red blood cells (RBCs) to the receptor-binding domain (RBD) of SARS-CoV-2 spike protein was placed on the card. 200 COVID-19 patient and 200 control plasma samples were reconstituted with O-negative RBCs to form whole blood and added to the dried protein, followed by a stirring step and a tilting step, 3-minute incubation, and a second tilting step. The sensitivity for the hemagglutination test, Euroimmun IgG ELISA test and RBD-based CoronaChek lateral flow assay was 87.0%, 86.5%, and 84.5%, respectively, using samples obtained from recovered COVID-19 individuals. Testing pre-pandemic samples, the hemagglutination test had a specificity of 95.5%, compared to 97.3% and 98.9% for the ELISA and CoronaChek, respectively.

In conclusion, we developed a novel rapid, point-of-care RBC agglutination test for the detection of SARS-CoV-2 antibodies that can yield semi-quantitative information on neutralizing antibody titer in patients. The five-minute test may find use in determination of serostatus prior to vaccination, post-vaccination surveillance and travel screening.

RESUMO

BACKGROUND: Previous research has shown diagnosis or screening for cancer may be a 'teachable moment' for prevention through lifestyle change. Previous trials have been successful but have been delivered via national programmes targeting patients being screened for colorectal cancer. This manuscript reports the protocol for a proof-of-concept study to assess the feasibility and acceptability of a lifestyle change service targeting men suspected or diagnosed with cancer of the prostate in a secondary care cancer service within the UK. METHODS: Lifestyle change will be promoted through integration of a lifestyle change service in a urology department in one NHS Board. The service is delivered by a Health Psychologist and uses motivational interviewing and behavioural change techniques to motivate and support patients to consider and address topics such as increasing physical activity and a healthy diet, smoking cessation, alcohol reduction and weight loss. A service evaluation will assess feasibility and acceptability via a patient experience survey, a survey exploring staff knowledge, attitudes and practice, pre- and post-intervention lifestyle behaviour survey and an audit of routine patient database. DISCUSSION: This pilot will assess the viability of using cancer testing and diagnosis as a teachable moment for lifestyle change in a unique population (i.e. men with suspected cancer of the prostate). If successful, this approach offers potential for preventative services to enhance routine and person-centred clinical cancer care provided within secondary care settings.

RESUMO

Introduction. Physical activity is important for health and well-being; however, rates of postnatal physical activity can be low. This paper reports the secondary outcomes of a trial aimed at increasing physical activity among postnatal women. Methods. More Active MuMs in Stirling (MAMMiS) was a randomised controlled trial testing the effect of physical activity consultation and pram walking group intervention among inactive postnatal women. Data were collected on postnatal weight, body composition, general well-being, and fatigue. Participants were also interviewed regarding motivations and perceived benefits of participating in the trial. Results. There was no significant effect of the intervention on any weight/body composition outcome or on general well-being at three or six months of follow-up. There was a significant but inconsistent difference in fatigue between groups. Qualitative data highlighted a number of perceived benefits to weight, body composition, and particularly well-being (including improved fatigue) which were not borne out by objective data. Discussion. The MAMMiS study found no impact of the physical activity intervention on body composition and psychological well-being and indicates that further research is required to identify successful approaches to increase physical activity and improve health and well-being among postnatal women.
