Introduction

Physical restraint (PR) is prescribed in patients receiving invasive mechanical ventilation in the intensive care unit (ICU) to avoid unplanned removal of medical devices. However, it is associated with an increased risk of delirium. We hypothesise that a restrictive use of PR, as compared with a systematic use, could reduce the duration of delirium in ICU patients receiving invasive mechanical ventilation.

Methods and analysis

The Restrictive use of Restraints and Delirium Duration in ICU (R2D2-ICU) study is a national multicentric, parallel-group, randomised (1:1) open-label, controlled, superiority trial, which will be conducted in 10 ICUs. A total of 422 adult patients requiring invasive mechanical ventilation for an expected duration of at least 48 hours and eligible for prescription of PR will be randomly allocated within 6 hours from intubation to either the restrictive PR use group or the systematic PR use group, until day 14, ICU discharge or death, whichever comes first. In both groups, PR will consist of the use of wrist straps. The primary endpoint will be delirium or coma-free days, defined as the number of days spent alive in the ICU without coma or delirium within the first 14 days after randomisation. Delirium will be assessed using the Confusion Assessment Method-ICU twice daily. Key secondary endpoints will encompass agitation episodes, opioid, propofol, benzodiazepine and antipsychotic drug exposure during the 14-day intervention period, along with a core outcome set of measures evaluated 90 days postrandomisation.

Ethics and dissemination

The R2D2-ICU study has been approved by the Comité de Protection des Personnes (CPP) ILE DE FRANCE III—PARIS (CPP19.09.06.37521) on June 10th, 2019). Participant recruitment started on 25 January 2021. Results will be published in international peer-reviewed medical journals and presented at conferences.

Predictive factors of clot propagation in patients with superficial venous thrombosis towards deep venous thrombosis and pulmonary embolism: a systematic review and meta-analysis

Por: van Royen · F. S.-A. · van Smeden · M. · van Doorn · S. · Rutten · F. H. · Geersing · G.-J. — Abril 16th 2024 at 18:01
Objective

A subset of patients with superficial venous thrombosis (SVT) experiences clot propagation towards deep venous thrombosis (DVT) and/or pulmonary embolism (PE). The aim of this systematic review is to identify all clinically relevant cross-sectional and prognostic factors for predicting thrombotic complications in patients with SVT.

Design

Systematic review.

Data sources

PubMed/MEDLINE and Embase were systematically searched until 3 March 2023.

Eligibility criteria

Original research studies with patients with SVT, DVT and/or PE as the outcome and presenting cross-sectional or prognostic predictive factors.

Data extraction and synthesis of results

The CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling (CHARMS) checklist for prognostic factor studies was used for systematic extraction of study characteristics. Per identified predictive factor, relevant estimates of univariable and multivariable predictor—outcome associations were extracted, such as ORs and HRs. Estimates of association for the most frequently reported predictors were summarised in forest plots, and meta-analyses with heterogeneity were presented. The Quality in Prognosis Studies (QUIPS) tool was used for risk of bias assessment and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) for assessing the certainty of evidence.

Results

Twenty-two studies were included (n=10 111 patients). The most reported predictive factors were high age, male sex, history of venous thromboembolism (VTE), absence of varicose veins and cancer. Pooled effect estimates were heterogenous and ranged from OR 3.12 (95% CI 1.75 to 5.59) for the cross-sectional predictor cancer to OR 0.92 (95% CI 0.56 to 1.53) for the prognostic predictor high age. The level of evidence was rated very low to low. Most studies were scored high or moderate risk of bias.

Conclusions

Although the pooled estimates of the predictors high age, male sex, history of VTE, cancer and absence of varicose veins showed predictive potential in isolation, variability in study designs, lack of multivariable adjustment and high risk of bias prevent firm conclusions. High-quality, multivariable studies are necessary to be able to identify individual SVT risk profiles.

Espiritualidad, vocación y sentido. Recursos generales de resistencia para profesionales de enfermería según la figura de San Juan de Dios

Este artículo tiene como objetivo elaborar una reflexión hacia aquellos elementos que actuaron como recursos espirituales en el proceso de formación de San Juan de Dios como enfermero y elaborar una serie de aportaciones actuales para reforzar el sentido de coherencia de las enfermeras post pandemia. Se utilizó la metodología historiográfica aplicada a historia de la enfermería para la reconstrucción de la memoria profesional, tomando como referencia y ejemplo la figura de San Juan de Dios y se recogieron los elementos siguiendo la herramienta de valoración espiritual FICA. Los textos muestran a Juan de Dios con un sentido de coherencia interna que se hizo posible a través de los recursos psico-espirituales de la época. Éstos facilitaron encontrar y desarrollar la vocación propia y la motivación para desarrollarla y alcanzar la autorrealización. La propuesta es contemplar en la profesionalización enfermera un cuidado por paraklesis, que implica presencia personal, actitud dialogal y palabra sapiencial, luminosa y alentadora siguiendo el modelo de San Juan de Dios, y su relación con el modelo de valoración espiritual FICA.

Interventions to improve latent and active tuberculosis treatment completion rates in underserved groups in low incidence countries: a scoping review

Por: Dretzke · J. · Hobart · C. · Basu · A. · Ahyow · L. · Nagasivam · A. · Moore · D. J. · Gajraj · R. · Roy · A. — Marzo 12th 2024 at 06:06
Background

People in underserved groups have higher rates of tuberculosis (TB) and poorer treatment outcomes compared with people with no social risk factors.

Objectives

This scoping review aimed to identify interventions that improve TB treatment adherence or completion rates.

Eligibility criteria

Studies of any design focusing on interventions to improve adherence or completion of TB treatment in underserved populations in low incidence countries.

Sources of evidence

MEDLINE, Embase and Cochrane CENTRAL were searched (January 2015 to December 2023).

Charting methods

Piloted data extraction forms were used. Findings were tabulated and reported narratively. Formal risk of bias assessment or synthesis was not undertaken.

Results

47 studies were identified. There was substantial heterogeneity in study design, population, intervention components, usual care and definition of completion rates. Most studies were in migrants or refugees, with fewer in populations with other risk factors (eg, homelessness, imprisonment or substance abuse). Based on controlled studies, there was limited evidence to suggest that shorter treatment regimens, video-observed therapy (compared with directly observed therapy), directly observed therapy (compared with self-administered treatment) and approaches that include tailored health or social support beyond TB treatment may lead to improved outcomes. This evidence is mostly observational and subject to confounding. There were no studies in Gypsy, Roma and Traveller populations, or individuals with mental health disorders and only one in sex workers. Barriers to treatment adherence included a lack of knowledge around TB, lack of general health or social support and side effects. Facilitators included health education, trusted relationships between patients and healthcare staff, social support and reduced treatment duration.

Conclusions

The evidence base is limited, and few controlled studies exist. Further high-quality research in well-defined underserved populations is needed to confirm the limited findings and inform policy and practice in TB management. Further qualitative research should include more people from underserved groups.

Effectiveness of non‐pharmacological interventions in improving sleep quality after cardiac surgery: A systematic review and meta‐analysis

Por: Pei Qi Peggy Soh · Wei Hao Timothy Wong · Tanushri Roy · Wilson Wai San Tam — Marzo 13th 2024 at 09:08

Abstract

Background

Sleep disturbance is highly prevalent among post-operative cardiac patients, with negative impacts on surgical recovery and rehabilitation. Post-operative pain and anxiety commonly seen in cardiac surgery patients are associated with poor sleep. Sleep medications commonly used are not ideal with prolonged usage, and non-pharmacological interventions can be good alternatives or complements.

Aim

To examine effectiveness of non-pharmacological interventions in post-operative cardiac settings on sleep quality, pain intensity and anxiety.

Design

Systematic review and meta-analysis.

Methods

PubMed, CENTRAL, Embase, CINAHL, Scopus, CNKI and ProQuest Dissertations and Theses were searched on 12 October 2022. Randomised controlled trials of non-pharmacological interventions examining sleep quality for adult post-operative cardiac patients were included. Included studies were appraised using Cochrane Risk of Bias tool version 1. Meta-analysis was conducted using RevMan version 5.4.1, and heterogeneity was assessed using I 2 statistics and Cochran Q's test.

Results

Eighteen studies involving 1701 participants were identified. Coronary artery bypass graft was most common. Non-pharmacological interventions varied in types and duration. All intervention groups were compared to usual care, placebo, no interventions or active comparators. Statistically significant improvement in sleep quality (SMD = −.91, 95% CI = −1.17 to −.65) was found among intervention groups that explored cognitive behavioural therapy, relaxation techniques, exercise, massage, acupressure, aromatherapy, music, eye mask and earplugs. Pain intensity was reduced (SMD = −.63, 95% CI = −1.05 to −.20) with cognitive behavioural therapy, relaxation techniques, massage, music and eye mask. Anxiety was improved (SMD = −.21, 95% CI = −.38 to −.04) with exercise and music.

Conclusion

The overall use of non-pharmacological interventions can optimise sleep after cardiac surgery. Further research with greater methodological rigour is needed to investigate different intervention-related characteristics while considering potential confounders.

Relevance to Clinical Practice

Post-operative cardiac settings can consider incorporating non-pharmacological interventions. Patients and healthcare providers can be better informed about the use of such interventions to improve sleep.

Factors Influencing Medication Administration Outcomes Among New Graduate Nurses Using Bar Code–Assisted Medication Administration

imageParamount to patient safety is the ability for nurses to make clinical decisions free from human error. Yet, the dynamic clinical environment in which nurses work is characterized by uncertainty, urgency, and high consequence, necessitating that nurses make quick and critical decisions. The aim of this study was to examine the influence of human and environmental factors on the decision to administer among new graduate nurses in response to alert generation during bar code–assisted medication administration. The design for this study was a descriptive, longitudinal, observational cohort design using EHR audit log and administrative data. The study was set at a large, urban medical center in the United States and included 132 new graduate nurses who worked on adult, inpatient units. Research variables included human and environmental factors. Data analysis included descriptive and inferential analyses. This study found that participants continued with administration of a medication in 90.75% of alert encounters. When considering the response to an alert, residency cohort, alert category, and previous exposure variables were associated with the decision to proceed with administration. It is important to continue to study factors that influence nurses' decision-making, particularly during the process of medication administration, to improve patient safety and outcomes.

Clinical supervision experience of nurses in or transitioning to advanced practice: A systematic review

Por: Debbie Zonneveld · Tiffany Conroy · Lauren Lines — Marzo 4th 2024 at 05:39

Abstract

Aims

To systematically explore the clinical supervision (CS) experience for nurses transitioning to advanced practice.

Design

A qualitative systematic review using Joanna Briggs Institute meta-aggregation following an a priori protocol published on PROSPERO (CRD42023426658).

Data Sources

Qualitative studies obtained from Medline, CINAHL, PsycINFO, Scopus, Emcare and ERIC databases and ProQuest dissertations and theses for peer-reviewed, published and unpublished studies from inception to July 2023.

Review Methods

Two authors conducted data screening and abstraction. Quality was appraised using the Critical Appraisal Skills Programme tool and reporting followed the Enhancing Transparency in Reporting the Synthesis of Qualitative Research checklist for systematic reviews.

Results

Sixteen studies contributed to five synthesized findings: CS that is beneficial requires structure and commitment, trusting relationships are foundational for learning, lifting burdens and preventing burnout, learning through reflection, critical thinking and feedback and barriers to CS.

Conclusions

This review provides a meaningful exploration of CS to support nurses transitioning to advanced practice. Well-structured supervision offers a safe space to share work-related concerns and develop an advanced practitioner identity. Sharing experiences helps alleviate work-related burdens and reduce professional isolation and burnout.

Implications for the Profession

Peer-support networks are vital for successful transition to advanced practice.

Impact

This review highlighted the impact of effective supervisory relationships in forming professional identity and possible links with nursing retention.

Public Contribution

No direct patient contributions are included as it forms part of a research degree.

The ILC Maine statement: Time for the fundamental care [r]evolution

Por: Alison Kitson · Devin Carr · Rebecca Feo · Tiffany Conroy · Lianne Jeffs — Febrero 21st 2024 at 07:45

Abstract

Aim

The aim of this study was to present the third position statement from the International Learning Collaborative (ILC). The ILC is the foremost global organization dedicated to transforming fundamental care. Internationally, fundamental care is reported to be poorly delivered, delayed or missed, negatively impacting patients, their families/carers and healthcare staff and systems. Overcoming this global challenge requires profound transformation in how our healthcare systems value, deliver and evaluate fundamental care. This transformation will take both evolutionary and revolutionary guises. In this position statement, we argue how this [r]evolutionary transformation for fundamental care can and must be created within clinical practice.

Design

Position paper.

Methods

This position statement stems from the ILC's annual conference and Leadership Program held in Portland, Maine, USA, in June 2023. The statement draws on the discussions between participants and the authors' subsequent reflections and synthesis of these discussions and ideas. The conference and Leadership Program involved participants (n = 209) from 13 countries working primarily within clinical practice.

Results

The statement focuses on what must occur to transform how fundamental care is valued, prioritized and delivered within clinical practice settings globally. To ensure demonstrable change, the statement comprises four action-oriented strategies that must be systematically owned by healthcare staff and leaders and embedded in our healthcare organizations and systems: Address non-nursing tasks: reclaim and protect time to provide high-value fundamental care. Accentuate the positive: change from deficit-based to affirmative language when describing fundamental care. Access evidence and assess impact: demonstrate transformation in fundamental care by generating relevant indicators and impact measures and rigorously synthesizing existing research. Advocate for interprofessional collaboration: support high-quality, transdisciplinary fundamental care delivery via strong nursing leadership.

Conclusion

The ILC Maine Statement calls for ongoing action – [r]evolution – from healthcare leaders and staff within clinical practice to prioritize fundamental care throughout healthcare systems globally.

Implications for the Profession and/or Patient Care

We outline four action-oriented strategies that can be embedded within clinical practice to substantially transform how fundamental care is delivered. Specific actions to support these strategies are outlined, providing healthcare leaders and staff a road map to continue the transformation of fundamental care within our healthcare systems.

Impact

Fundamental care affects everyone across their life course, regardless of care context, clinical condition, age and/or the presence of disability. This position statement represents a call to action to healthcare leaders and staff working specifically in clinical practice, urging them to take up the leadership challenge of transforming how fundamental care is delivered and experience globally.

Patient or Public Contribution

Patients, service users and caregivers were involved in the ILC annual conference, thus contributing to the discussions that shaped this position statement.

What Does this Paper Contribute to the Wider Global Clinical Community?

The strategies and actions outlined in this position statement are relevant to all clinical settings globally, providing practical strategies and actions that can be employed to enhance fundamental care for all patients and their families/carers. By outlining the importance of both evolutionary and revolutionary change, we identify ways in which healthcare systems globally can begin making the necessary steps towards radical fundamental care transformation, regardless of where they are in the change journey.

"Just as curry is needed to eat rice, antibiotics are needed to cure fever"--a qualitative study of individual, community and health system-level influences on community antibiotic practices in rural West Bengal, India

Por: Gautham · M. · Bhattacharyya · S. · Maity · S. · Roy · M. B. · Balasubramaniam · P. · Ebata · A. · Bloom · G. — Febrero 8th 2024 at 03:36
Objectives

To understand community antibiotic practices and their drivers, comprehensively and in contextually sensitive ways, we explored the individual, community and health system-level factors influencing community antibiotic practices in rural West Bengal in India.

Design

Qualitative study using focus group discussions and in-depth interviews.

Setting

Two contrasting village clusters in South 24 Parganas district, West Bengal, India. Fieldwork was conducted between November 2019 and January 2020.

Participants

98 adult community members (42 men and 56 women) were selected purposively for 8 focus group discussions. In-depth interviews were conducted with 16 community key informants (7 teachers, 4 elected village representatives, 2 doctors and 3 social workers) and 14 community health workers.

Results

Significant themes at the individual level included sociodemographics (age, gender, education), cognitive factors (knowledge and perceptions of modern antibiotics within non-biomedical belief systems), affective influences (emotive interpretations of appropriate medicine consumption) and economic constraints (affordability of antibiotic courses and overall costs of care). Antibiotics were viewed as essential fever remedies, akin to antipyretics, with decisions to halt mid-course influenced by non-biomedical beliefs associating prolonged use with toxicity. Themes at the community and health system levels included the health stewardship roles of village leaders and knowledge brokering by informal providers, pharmacists and public sector accredited social health activists. However, these community resources lacked sufficient knowledge to address people’s doubts and concerns. Qualified doctors were physically and socially inaccessible, creating a barrier to seeking their expertise.

Conclusions

The interplay of sociodemographic, cognitive and affective factors, and economic constraints at the individual level, underscores the complexity of antibiotic usage. Additionally, community leaders and health workers emerge as crucial players, yet their knowledge gaps and lack of empowerment pose challenges in addressing public concerns. This comprehensive analysis highlights the need for targeted interventions that address both individual beliefs and community health dynamics to promote judicious antibiotic use.

Describing Medication Administration and Alert Patterns Experienced by New Graduate Nurses During the First Year of Practice

Por: Sloss, Elizabeth Ann · Jones, Terry L. · Baker, Kathy · Robins, Jo Lynne W. · Thacker, Leroy R. — Diciembre 13th 2023 at 01:00
imageThe aim of this study was to describe medication administration and alert patterns among a cohort of new graduate nurses over the first year of practice. Medical errors related to clinical decision-making, including medication administration errors, may occur more frequently among new graduate nurses. To better understand nursing workflow and documentation workload in today's clinical environment, it is important to understand patterns of medication administration and alert generation during barcode-assisted medication administration. Study objectives were addressed through a descriptive, longitudinal, observational cohort design using secondary data analysis. Set in a large, urban medical center in the United States, the study sample included 132 new graduate nurses who worked on adult, inpatient units and administered medication using barcode-assisted medication administration. Data were collected through electronic health record and administration sources. New graduate nurses in the sample experienced a total of 587 879 alert and medication administration encounters, administering 772 unique medications to 17 388 unique patients. Nurses experienced an average medication workload of 28.09 medications per shift, 3.98% of which were associated with alerts, over their first year of practice. In addition to high volume of medication administration, new graduate nurses administer many different types of medications and are exposed to numerous alerts while using barcode-assisted medication administration.

Introduction

Individuals with dementia face an increased risk of falls. Falls can cause a decline in the individual’s overall functionality. All types of falls, including those that do not result in injury, can lead to psychosocial consequences, such as diminished confidence and a fear of falling. Projections indicate a rising trend in dementia diagnoses, implying an increase in fall incidents. Yet, there is a lack of evidence to support interventions for people living with dementia who have fallen. Our objective is to test the feasibility of a falls intervention trial for people with dementia.

Method and analysis

This is a UK-based two-arm pilot cluster randomised controlled trial. In this study, six collaborating sites, which form the clusters, will be randomly allocated to either the intervention arm or the control arm (receiving treatment as usual) at a 1:1 ratio. During the 6 month recruitment phase, each cluster will enrol 10 dyads, comprising 10 individuals with dementia and their respective carers, leading to a total sample size of 60 dyads. The primary outcomes are the feasibility parameters for a full trial (ie, percentage consented, follow-up rate and cost framework). Secondary outcomes include activities of daily living, quality of life, fall efficacy, mobility, goal attainment, cognitive status, occurrence of falls, carer burden and healthcare service utilisation. Outcome measures will be collected at baseline and 28 weeks, with an additional assessment scheduled at 12 weeks for the healthcare service utilisation questionnaire. An embedded process evaluation, consisting of interviews and observations with participants and healthcare professionals, will explore how the intervention operates and the fidelity of study processes.

Ethics and dissemination

The study was approved by the NHS and local authority research governance and research ethics committees (NHS REC reference: 23/WA/0126). The results will be shared at meetings and conferences and will be published in peer-reviewed journals.

COVID‐19 and collective trauma: Implementing a trauma‐informed model of care for post‐COVID patients

Por: Carly Barton · Lauren Troy · Alan Teoh · Lissa Spencer · Jack Reeves · Vincent Cram · Michael Wai · Lynette Jones — Enero 31st 2024 at 11:52

Abstract

Aim

To describe the implementation of a trauma-informed model of care in the Post COVID Respiratory Clinic of a large tertiary referral centre in NSW.

Design

Discussion paper.

Data Sources

Evidence gathered from a literature search (2008–2022) was used to develop a framework for management of patients presenting to this Post COVID Respiratory Clinic. This paper outlines the personal reflections of the clinic staff as they developed and implemented this framework. Ethical approval was obtained to report the data collected from patient reviews.

Discussion

The literature highlights the high prevalence of trauma in patients following COVID-19 infection, as well as the larger population both during and after the pandemic. This experience of trauma was observed in patients seen within the clinic, indicating a need for specialized care. In response, a trauma-informed model of care was implemented.

Conclusion

Reconceptualizing COVID-19 as a ‘collective trauma’ can help healthcare workers understand the needs of post-COVID patients and enable them to respond empathetically. A trauma-informed model is complementary to this cohort as it specifically addresses vulnerable populations, many of whom have been further marginalized by the pandemic.

Implications for Nursing and Patient Care

Frontline healthcare workers, particularly nurses, are well positioned to implement trauma-informed care due to their high-level of patient contact. Adequate allocation of resources and investment in staff is essential to ensure such care can be provided.

Impact

The COVID-19 pandemic has led to adverse physical and mental health outcomes for many. Trauma-informed care is a way to promote reengagement with the healthcare system in this group. Post COVID patients globally may benefit from this approach, as it aims to build trust and independence.

Patient or Public Contribution

Feedback was sought from a patient representative to ensure this paper adequately reflected the experience of the post-COVID patient.

Rat hair-follicle-associated pluripotent (HAP) stem cells can differentiate into atrial or ventricular cardiomyocytes in culture controlled by specific supplementation

by Nanako Takaoka, Michiko Yamane, Ayami Hasegawa, Koya Obara, Kyoumi Shirai, Ryoichi Aki, Hiroyasu Hatakeyama, Yuko Hamada, Nobuko Arakawa, Manabu Tanaka, Robert M. Hoffman, Yasuyuki Amoh

There has been only limited success to differentiate adult stem cells into cardiomyocyte subtypes. In the present study, we have successfully induced beating atrial and ventricular cardiomyocytes from rat hair-follicle-associated pluripotent (HAP) stem cells, which are adult stem cells located in the bulge area. HAP stem cells differentiated into atrial cardiomyocytes in culture with the combination of isoproterenol, activin A, bone morphogenetic protein 4 (BMP4), basic fibroblast growth factor (bFGF), and cyclosporine A (CSA). HAP stem cells differentiated into ventricular cardiomyocytes in culture with the combination of activin A, BMP4, bFGF, inhibitor of Wnt production-4 (IWP4), and vascular endothelial growth factor (VEGF). Differentiated atrial cardiomyocytes were specifically stained for anti-myosin light chain 2a (MLC2a) antibody. Ventricular cardiomyocytes were specially stained for anti-myosin light chain 2v (MLC2v) antibody. Quantitative Polymerase Chain Reaction (qPCR) showed significant expression of MLC2a in atrial cardiomyocytes and MLC2v in ventricular cardiomyocytes. Both differentiated atrial and ventricular cardiomyocytes showed characteristic waveforms in Ca2+ imaging. Differentiated atrial and ventricular cardiomyocytes formed long myocardial fibers and beat as a functional syncytium, having a structure similar to adult cardiomyocytes. The present results demonstrated that it is possible to induce cardiomyocyte subtypes, atrial and ventricular cardiomyocytes, from HAP stem cells.

Identification of viral protein R of human immunodeficiency virus-1 (HIV) and interleukin-6 as risk factors for malignancies in HIV-infected individuals: A cohort study

by Akihiro Matsunaga, Naokatsu Ando, Yuko Yamagata, Mari Shimura, Hiroyuki Gatanaga, Shinichi Oka, Yukihito Ishizaka

Background

Despite effective antiretroviral therapy, patients with human immunodeficiency virus type-1 (HIV) suffer from a high frequency of malignancies, but related risk factors remain elusive. Here, we focused on blood-circulating viral protein R (Vpr) of HIV, which induces proinflammatory cytokine production and genotoxicity by exogenous functions.

Methods and findings

A total 404 blood samples of HIV patients comprising of 126 patients with malignancies (tumor group) and 278 patients without malignancies (non-tumor group), each of 96 samples was first selected by one-to-one propensity score matching. By a detergent-free enzyme-linked immunosorbent assays (detection limit, 3.9 ng/mL), we detected Vpr at a higher frequency in the matched tumor group (56.3%) than in the matched non-tumor group (39.6%) (P = 0.030), although there was no different distribution of Vpr levels (P = 0.372). We also detected anti-Vpr immunoglobulin (IgG), less frequently in the tumor group compared with the tumor group (22.9% for tumor group vs. 44.8% for non-tumor group, P = 0.002), and the proportion of patients positive for Vpr but negative of anti-Vpr IgG was significantly higher in the tumor group than in the non-tumor group (38.6% vs. 15.6%, respectively, P P P P = 0.010). Finally, multivariate logistic regression analysis suggested a positive link of Vpr with tumor occurrence in HIV patients (P = 0.002).

Conclusion

Vpr and IL-6 could be risk factors of HIV-1 associated malignancies, and it would be importance to monitor these molecules for well managing people living with HIV-1.

“High blood pressure comes from thinking too much”: Understandings of illness among couples living with cardiometabolic disorders and HIV in Malawi

by Jane Jere, Allison Ruark, Julie T. Bidwell, Rita M. Butterfield, Torsten B. Neilands, Sheri D. Weiser, Nancy Mulauzi, James Mkandawire, Amy A. Conroy

Cardiometabolic disorders (CMD) such as hypertension and diabetes are increasingly prevalent in sub-Saharan Africa, placing people living with HIV at risk for cardiovascular disease and threatening the success of HIV care. Spouses are often the primary caregivers for people living with CMD, and understanding patients’ and partners’ conceptions of CMD could inform care. We conducted semi-structured interviews with 25 couples having a partner living with HIV and either hypertension or diabetes. Couples were recruited from HIV clinics in Malawi and were interviewed on beliefs around symptoms, causation, prevention, and treatment for CMD. Data were analyzed at the individual and dyadic levels using framework analysis and Kleinman’s theory of explanatory models as a lens. On average, participants were 51 years old and married for 21 years. Approximately 57%, 14%, and 80% had hypertension, diabetes, and HIV. Couples endorsed a combination of biomedical explanatory models (beliefs around physical and mental health) and traditional explanatory models (beliefs around religion and natural remedies), although tended to emphasize the biomedical model. Half of couples believed stress was the main cause of hypertension. For diabetes, diet was believed to be a common cause. In terms of prevention, dietary changes and physical activity were most frequently mentioned. For disease management, medication adherence and diet modifications were emphasized, with some couples also supporting herbal remedies, stress reduction, and faith in God as strategies. Participants were generally more concerned about CMD than HIV due to poor access to CMD medications and beliefs that CMD could lead to sudden death. Within couples, partners often held many of the same beliefs but diverged around which etiological or preventive factors were most important (e.g., stress versus diet) and the best diet for CMD. Health education programs should involve primary partners to build knowledge of CMD and address overlap with HIV, and reinforce accurate information on lifestyle factors for the prevention and treatment of CMD.

Impact of virtual reality‐based therapy on post‐stroke depression: A systematic review and meta‐analysis of randomized controlled trials

Abstract

Background

Post-stroke depression is the most common neuropsychiatric consequence and reduces rehabilitation effectiveness. However, the efficacy of virtual reality (VR) on mental health treatment for patients after a stroke is uncertain.

Aims

The aim of this study was to evaluate the efficacy of VR as a co-adjuvant form of treatment to reduce depression in stroke patients admitted to neurorehabilitation units.

Methods

We systematically searched medical databases including PubMed, CINAHL, PsycINFO, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov from inception to November 16, 2023. Clinical trials comparing the use of VR as an adjuvant form of treatment in stroke patients' rehabilitation with the usual treatment were included. Pooled standardized mean differences were calculated using a random-effects model. Subgroup analyses were performed according to type of stroke, VR characteristics, and the scale used to measure depression. Meta-regression analysis was performed for intervention duration and to determine the mean age of the participants.

Results

Eight studies and 388 stroke patients were included. The VR interventions were associated with a lower risk of depression in patients (ES = −0.69; 95% CI [−1.05, −0.33]; I 2 = 57.6%; p ≤ .02). The estimates were not affected by the type of stroke, the type of VR used, the blinding process, the type of scale used to detect depression, the duration of the intervention (weeks and minutes), and the total number of sessions. Meta-regression shows that younger samples (p = .00; 95% CI [0.01, 0.08) and longer interventions (p = < .05; 95% CI [−0.00, −0.00) lead to a greater reduction in depression.

Linking Evidence to Action

This review provides an important basis for treating depression in patients after a stroke. Professionals working in stroke neurorehabilitation units should consider VR as a form of co-adjuvant treatment for depression in patients.

The methionine addiction of cancer cells is known as the Hoffman effect. While non-cancer cells in culture can utilize homocysteine in place of methionine for cellular growth, most cancer cells require exogenous methionine for proliferation. It has been suggested that a biochemical basis of this effect is the increased utilization of methionine for S-adenosylmethionine, the major methyl donor for a variety of cellular methyltransferases. Recent studies have pointed to the role of S-adenosylmethionine-dependent protein arginine methyltransferases (PRMTs) in cell proliferation and cancer. To further understand the biochemical basis of the methionine addiction of cancer cells, we compared protein arginine methylation in two previously described isogenic cell lines, a methionine-addicted 143B human osteosarcoma cell line and its less methionine-dependent revertant. Previous work showed that the revertant cells were significantly less malignant than the parental cells. In the present study, we utilized antibodies to detect the asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) products of PRMTs in polypeptides from cellular extracts and purified histone preparations of these cell lines fractionated by SDS-PAGE. Importantly, we observed little to no differences in the banding patterns of ADMA- and SDMA-containing species between the osteosarcoma parental and revertant cell lines. Furthermore, enzymatic activity assays using S-adenosyl-ʟ-[methyl-3H] methionine, recombinantly purified PRMT enzymes, cell lysates, and specific PRMT inhibitors revealed no major differences in radiolabeled polypeptides on SDS-PAGE gels. Taken together, these results suggest that changes in protein arginine methylation may not be major contributors to the Hoffman effect and that other consequences of methionine addiction may be more important in the metastasis and malignancy of osteosarcoma and potentially other cancers.

This study aimed to elucidate the influence of horizontal resistance loads on the spatiotemporal and ground reaction force (GRF) variables during maximal sprint acceleration. Nine male sprinters (20.2 ± 1.2 years; 175.3 ± 4.5 cm, 69.7 ± 6.1 kg) performed sprint-running with six loading conditions of one unresisted and five resisted loads of 4, 6, 8, 10, and 12 kg using a resistance training device with intelligent drag technology. During the trials, the GRFs for all steps were determined using a 50-m force plate system. The spatiotemporal and GRF variables at running velocity of every 0.5 m/s were obtained and compared across the loading conditions. The maximal running velocity under 0, 4, 6, 8, 10, and 12 kg loading conditions were 9.84 ± 0.41, 8.55 ± 0.41, 8.09 ± 0.33, 7.62 ± 0.34, 7.11 ± 0.31, and 6.71 ± 0.29 m/s, respectively. ANOVA revealed significant main effects of load on the measured variables (η2 = 0.236–0.715, p

El consumo colectivo de alcohol en jóvenes: un estudio cualitativo con perspectiva de género

Los jóvenes entre 15-24 años son el grupo de edad que más participa del binge drinking, conocido como botellón en España. Son escasos los estudios de esta problemática con perspectiva de género. Por ello, exploramos los discursos y opiniones acerca del consumo colectivo de alcohol con perspectiva de género en jóvenes universitarios. Estudio cualitativo descriptivo. La recogida de información se realizó mediante grupos de discusión en Sevilla en febrero y marzo de 2019. Participaron 32 estudiantes de enfermería de primer curso. Para el análisis de los datos se siguieron los pasos de Taylor-Bogdan. Se hicieron cuatro grupos, de edad entre 18-24 años. Se obtuvieron las siguientes categorías: tipología y forma de consumo, roles sociales y conductas. Las conclusiones fueron que las diferencias de género quedan plasmadas en el discurso del alumnado, destacando las disimilitudes de conducta entre géneros y la mayor culpabilidad que sufren las mujeres. El género femenino es el más señalado al exceder los límites y el más vulnerable en el ocio nocturno. Esto sugiere la necesidad de generar intervenciones orientadas a resignificar los estereotipos del modelo patriarcal asociados al género y al consumo de alcohol, para minimizar conductas de riesgo en el ocio juvenil.
