The increasing pressure of their professional duties has led to a notable concern regarding the mounting anxiety levels among nurses. The ongoing discussion revolves around the efficacy of mindfulness as a means to alleviate anxiety in nurses.
This systematic review evaluated the effectiveness of mindfulness in reducing anxiety among nurses.
The evaluation followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. An extensive and comprehensive search was conducted across eight databases to identify studies that utilized randomized controlled trials (RCTs) and were published in English between 2011 and 2022. Independently, two reviewers assessed the validity of the randomized controlled trials using the Consolidated Standards of Reporting Trials criteria. Additionally, two authors independently employed the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-2) method to evaluate the potential bias in the RCTs.
Eight randomized controlled trial studies that were deemed eligible were included in the current analysis. Based on the literature review, it was determined that mindfulness-based training can assist nurses in reducing their anxiety levels. Furthermore, the effectiveness of mindfulness-based programs in enhancing nurses' mindfulness and self-compassion has been firmly established.
Based on existing literature, mindfulness-based interventions have proven to be effective in reducing anxiety levels among nurses. However, in order to enhance the overall quality of research, it is necessary to implement more rigorous controlled designs that include randomization. Additionally, larger sample sizes with a diverse range of participants are needed to establish and validate the effectiveness of mindfulness-based programs in alleviating anxiety among nurses.
Implementing mindfulness-based training in healthcare organizations can offer numerous benefits. One such advantage is that it can help nurses in reducing anxiety and enhancing their ability to handle the pressures associated with their profession.

Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed ‘prehabilitation’) may mitigate these side effects and improve quality of life.
During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that ‘packaged’ care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme.
This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20–30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them.
The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences.

Co-creation approaches, such as co-design and co-production, aspire to power-sharing and collaboration between service providers and service users, recognising the specific insights each group can provide to improve health and other public services. However, an intentional focus on equity-based approaches grounded in lived experience and epistemic justice is required considering entrenched structural inequities between service-users and service-providers in public and institutional spaces where co-creation happens.
This paper presents a Charter of tenets and principles to foster a new era of ‘Equity-based Co-Creation’ (EqCC).
The Charter is based on themes heard during an International Forum held in August 2022 in Ontario, Canada, where 48 lived experience experts and researchers were purposively invited to deliberate challenges and opportunities in advancing equity in the co-creation field.
The Charter’s seven tenets—honouring worldviews, acknowledging ongoing and historical harms, operationalising inclusivity, establishing safer and brave spaces, valuing lived experiences, ‘being with’ and fostering trust, and cultivating an EqCC heartset/mindset—aim to promote intentional inclusion of participants with intersecting social positions and differing historic oppressions. This means honouring and foregrounding lived experiences of service users and communities experiencing ongoing structural oppression and socio-political alienation—Black, Indigenous and people of colour; disabled, Mad and Deaf communities, women, 2S/LGBTQIA+ communities, people perceived to be mentally ill and other minoritised groups—to address epistemic injustice in co-creation methodologies and practice, thereby providing opportunities to begin to dismantle intersecting systems of oppression and structural violence.
Each Charter tenet speaks to a multilayered, multidimensional process that is foundational to shifting paradigms about redesigning our health and social systems and changing our relational practices. Readers are encouraged to share their reactions to the Charter, their experiences implementing it in their own work, and to participate in a growing international EqCC community of practice.
To determine and describe what interventions exist to improve nurse–family communication during the waiting period of an emergency department visit.
Communication between nurses and families is an area needing improvement. Good communication can improve patient outcomes, satisfaction with care and decrease patient and family anxiety.
Scoping Review.
A scoping review was conducted following the Joanna Briggs Institution methodology: (1) identify the research question, (2) define the inclusion criteria, (3) use a search strategy to identify relevant studies using a three-step approach, (4) select studies using a team approach, (5) data extraction, (6) data analysis, and (7) presentation of results.
Medline, CINAHL, EMBASE, PsychInfo and grey literature were searched on 3 August 2022.
The search yielded 1771 articles from the databases, of which 20 were included. An additional seven articles were included from the grey literature. Paediatric and adult interventions were found targeting staff and family of which the general recommendations were summarised into communication models.
Future research should focus on evaluating the effectiveness of interventions using a standardised scale, understanding the specific needs of families, and exploring the communication models developed in this review.
Communication models for triage nurses and all emergency department nurses were developed. These may guide nurses to improve their communication which will contribute to improving family satisfaction.

To evaluate the impact of nurse care changes in implementing a blood pressure management protocol on achieving rapid, intensive and sustained blood pressure reduction in acute intracerebral haemorrhage patients.
Retrospective cohort study of prospectively collected data over 6 years.
Intracerebral haemorrhage patients within 6 h and systolic blood pressure ≥ 150 mmHg followed a rapid (starting treatment at computed tomography suite with a target achievement goal of ≤60 min), intensive (target systolic blood pressure < 140 mmHg) and sustained (maintaining target stability for 24 h) blood pressure management plan. We differentiated six periods: P1, stroke nurse at computed tomography suite (baseline period); P2, antihypertensive titration by stroke nurse; P3, retraining by neurologists; P4, integration of a stroke advanced practice nurse; P5, after COVID-19 impact; and P6, retraining by stroke advanced practice nurse. Outcomes included first-hour target achievement (primary outcome), tomography-to-treatment and treatment-to-target times, first-hour maximum dose of antihypertensive treatment and 6-h and 24-h systolic blood pressure variability.
Compared to P1, antihypertensive titration by stroke nurses (P2) reduced treatment-to-target time and increased the rate of first-hour target achievement, retraining of stroke nurses by neurologists (P3) maintained a higher rate of first-hour target achievement and the integration of a stroke advanced practice nurse (P4) reduced both 6-h and 24-h systolic blood pressure variability. However, 6-h systolic blood pressure variability increased from P4 to P5 following the impact of the COVID-19 pandemic. Finally, compared to P1, retraining of stroke nurses by stroke advanced practice nurse (P6) reduced tomography-to-treatment time and increased the first-hour maximum dose of antihypertensive treatment.
Changes in nursing care and continuous education can significantly enhance the time metrics and blood pressure outcomes in acute intracerebral haemorrhage patients.

For individuals with mobility limitations, virtual exercise programmes can address the challenges of in-person participation in community exercise programmes. A synthesis of studies of virtual exercise programmes targeting mobility limitations provided outside of conventional rehabilitation services and strategies used to optimise equitable access and inclusivity in these programmes is lacking. We aim to characterise evaluations of virtual exercise programmes for adults with mobility limitations, and the nature of and extent to which equity, diversity and inclusion considerations are integrated in the research process.
A scoping review following a six-stage methodological framework, including a consultation exercise, is proposed. A comprehensive strategy will be used to search Medline, Embase, PEDro, CINAHL and Scopus to identify peer-reviewed studies evaluating virtual exercise programmes for adults with mobility limitations living in the community. Three trained reviewers will select studies independently. Data (eg, study methodology, programme structure and content, participant characteristics) will be extracted using a standardised form, and collated and summarised using quantitative and qualitative methods. The PROGRESS-Plus and International Classification of Functioning, Disability and Health frameworks will be used to classify participant characteristics and study outcomes, respectively. During the consultation exercise, key knowledge users, including exercise participants, programme providers and coordinators, and members of community organisations for persons living with disabilities and under-represented groups, will be asked to provide insights regarding the applicability of review findings. A directed content analysis of data from the consultation exercise will be performed.
The research ethics board at the University of Toronto approved the consultation exercise. Findings will be disseminated through peer-reviewed publications and conference presentations. Findings will enhance understanding of current research evaluating virtual exercise programmes and inform future research and strategies for promoting equitable access and outcomes for individuals with mobility limitations.
There is a growing consensus to reduce the use of restrictive care practices in mental health settings to minimise the physical and psychological complications for patients. However, data regarding restrictive care practice use and factors contributing to variations in the proportion estimates has not previously been synthesised.
This study aimed to synthesise evidence on (1) the pooled proportions of physical restraint, seclusion or chemical restraint in adult mental health inpatients and (2) sources of variability in these proportion estimates.
Studies were identified from Scopus, MEDLINE, PsycINFO, Web of Science, Embase and CINAHL databases following the PRISMA 2020 guidelines. We conducted a meta-analysis of studies published in English language from 1 January 2010 to 15 August 2022. Binomial data were pooled using a random effect model, with 95% confidence intervals. Meta-regression was also computed to identify factors that may contribute to variations in the proportion estimates.
A total of 77 studies were included in this meta-analysis. The pooled prevalence of physical restraint, seclusion and chemical restraint was 14.4%, 15.8% and 25.7%, respectively. Data were heterogeneous across studies (I 2 > 99%). Reporting practices and geographical locations contributed to the variability in the reported estimates of restrictive care practices, with studies from Asian countries reporting higher proportions.
There appear differences between geographical locations in the proportion of restrictive practices in mental health inpatients; however, this is complicated by how these prevalence data have been measured and defined. Consistency in the reporting of restrictive care practices in mental health is required to make valid comparisons between geographical regions, policy settings and practice innovations.
Efforts are needed to develop training programmes and policy changes to ensure consistency in defining and reporting of restrictive care practices in mental health facilities.
This is a systematic review that analysed data from previously published studies, and there was no patient/public contribution in this study.

Dexmedetomidine is a promising pharmaceutical strategy to minimise opioid use during surgery. Despite its growing use, it is uncertain whether dexmedetomidine can improve patient-centred outcomes such as quality of recovery and pain.
We will conduct a systematic review and meta-analysis following the recommendations of the Cochrane Handbook for Systematic Reviews. We will search MEDLINE, Embase, CENTRAL, Web of Science and CINAHL approximately in October 2023. We will include randomised controlled trials evaluating the impact of systemic intraoperative dexmedetomidine on patient-centred outcomes. Patient-centred outcome definition will be based on the consensus definition established by the Standardised Endpoints in Perioperative Medicine initiative (StEP-COMPAC). Our primary outcome will be the quality of recovery after surgery. Our secondary outcomes will be patient well-being, function, health-related quality of life, life impact, multidimensional assessment of postoperative acute pain, chronic pain, persistent postoperative opioid use, opioid-related adverse events, hospital length of stay and adverse events. Two reviewers will independently screen and identify trials and extract data. We will evaluate the risk of bias of trials using the Cochrane Risk of Bias Tool (RoB 2.0). We will synthesise data using a random effects Bayesian model framework, estimating the probability of achieving a benefit and its clinical significance. We will assess statistical heterogeneity with the tau-squared and explore sources of heterogeneity with meta-regression. We have involved patient partners, clinicians, methodologists, and key partner organisations in the development of this protocol, and we plan to continue this collaboration throughout all phases of this systematic review.
Our systematic review does not require research ethics approval. It will help inform current clinical practice guidelines and guide development of future randomised controlled trials. The results will be disseminated in open-access peer-reviewed journals, presented at conferences and shared among collaborators and networks.

This study aimed to assess mental health nurses' empathy towards consumers with dual diagnosis in Australian mental health settings. The research question was What is mental health nurses' empathy towards consumers with co-existing mental health and drug and alcohol problems?
A cross-sectional survey was carried out to understand mental health nurses' empathy. The convenience sample included 96 mental health nurses from various mental health settings with experience working with consumers with dual diagnosis. We assessed empathy using the Toronto Empathy Questionnaire. We utilised SPSS™ software to analyse both the descriptive data and multiple-regression.
The mean empathy score was 47.71 (SD 8.28). The analysis of the association between demographic variables and individual subscales showed an association between the clinical setting and empathy (p = .031) and sympathetic physiological arousal (p = .049). The work sector was associated with sympathetic physiological arousal (p = .045) and conspecific altruism (p = .008). Emotional contagion (β = .98, p < .001), emotional comprehension (β = 1.02, p < .001), sympathetic physiological arousal (β = 1.01, p < .001) and conspecific altruism (β = 10.23, p < .001) predicted mental health nurses' empathy.
This study found that most mental health nurses showed empathy towards consumers with dual diagnosis. Mental health nurses who are more empathetic towards their consumers experience emotional contagion. They understand emotions better, show sympathetic physiological responses and exhibit kind behaviour towards consumers.
Further research is required to understand how mental health nurses adapt to consumers' emotional states in different mental health settings. This information can help clinicians make better decisions about care quality for consumers with dual diagnosis.
This study addressed mental health nurses' empathy towards consumers with dual diagnosis. Mental health nurses showed increased empathy towards consumers with dual diagnosis. The empathy levels vary based on age, clinical setting, work sector and work experience. Mental health nurses' empathy levels were predicted by emotional contagion, emotion comprehension, sympathetic physiological arousal and conspecific altruism. Empathy enhancement among mental health nurses, particularly towards consumers with dual diagnosis, is crucial and should be regarded as a top priority by healthcare leaders and educators.

BackgroundDespite promising signs of the benefits associated with Antimicrobial Stewardship Programs (ASPs), there remains limited knowledge on how to implement ASPs in peculiar settings for a more elaborate impact. This study explored prescriber experiences and perceptions of the usefulness, and feasibility of strategies employed for the implementation of antimicrobial stewardship (AMS) interventions as well as challenges encountered.
MethodsThis is a cross-sectional mixed-method survey of prescribers’ perspective of the facilitators and barriers of implementing ASP. The quantitative approach comprised of a semi-structured questionnaire and data collected were analyzed using SPSS version 26 while the qualitative approach used focus group discussions followed by content analysis.
ResultsOut of the thirty people that participated in the workshop, twenty-five completed the questionnaires which were analyzed. The respondents included 15 (60.0%) medical doctors and 10 (40.0%) pharmacists. The mean age of the respondents was 36.39±7.23 years with mean year of practice of 9.48±6.01 years. Majority of them (84.0%) were in a position to provide input on the implementation of AMS in their facilities, although their managements had the final decision. The pharmacists (100%) were more likely to agree that antibiotic resistance was a problem for their practice than the medical doctors (78.6%) while equal number (80.0%) of respondents (pharmacists and medical doctors) believed that inappropriate prescribing was a problem. Having a specialized and dedicated team with effective monitoring was recognized as crucial for effective ASP while inadequate personnel was identified as a major barrier. We identified stakeholder’s engagement, policies and regulation, as well as education as themes for improving AMS in the country.
ConclusionThe results gave insight into the prescribers’ perspective on the facilitators and barriers to antimicrobial stewardship; challenges and possible solutions to implementing ASPs in health facilities in Lagos State. We further identified pertinent contextual factors that need to be addressed when developing ASPs in healthcare facilities in a resource-poor setting.

This study aimed to evaluate the dislodgement resistance and structural changes of different mineral trioxide aggregate cements (MTA) like Pro-Root MTA, Ortho MTA, and Retro MTA after exposure to sodium hypochlorite (NaOCl), NaOCl-Ethylenediaminetetraacetic acid (EDTA), 1-hydroxyethylidene-1, 1-bisphosphonate (Dual Rinse HEDP), and NaOCl-Maleic acid (MA). The root canal spaces of 150 dentine slices were obturated using tricalcium silicate cements and divided into 3 groups (n = 50): Group1: ProRoot MTA, Group2: Retro MTA, and Group3: Ortho MTA. The samples in each group were further subdivided into four experimental (n = 10) and one control groups (n = 10): 2.5% NaOCl-17% EDTA, Dual Rinse HEDP, 2.5% NaOCl-7% Maleic acid, 2.5% NaOCl, distilled water (control). The dislodgement resistance and structural changes of cements were measured. Use of DR HEDP resulted in higher dislodgement resistance compared to17% EDTA and 7% MA in the samples obturated with Ortho MTA and Pro-Root MTA (p
No abstract available This study provides an overview of the literature to identify and map the types of available evidence on self-supporting mobile applications used by nurses in wound care regarding their development, evaluation and outcomes for patients, nurses and the healthcare system.
Scoping review.
Joanna Briggs Institute scoping review methodology was used.
A search was performed using MEDLINE, Embase, CINAHL (via EBSCO), Web of Science, LiSSa (Littérature Scientifique en Santé), Cochrane Wounds, Érudit and grey literature, between April and October 2022, updated in April 2023, to identify literature published in English and French.
Eleven studies from 14 publications met the inclusion criteria. Mostly descriptive, the included studies presented mobile applications that nurses used, among other things, to assess wounds and support clinical decision-making. The results described how nurses were iteratively involved in the process of developing and evaluating mobile applications using various methods such as pilot tests. The three outcomes most frequently reported by nurses were as follows: facilitating care, documentation on file and access to evidence-based data.
The potential of mobile applications in wound care is within reach. Nurses are an indispensable player in the successful development of these tools.
If properly developed and evaluated, mobile applications for wound care could enhance nursing practices and improve patient care. The development of ethical digital competence must be ensured during initial training and continued throughout the professional journey.
We identified a dearth of studies investigating applications that work without Internet access. More research is needed on the development of mobile applications in wound care and their possible impact on nursing practice in rural areas and the next generation of nurses.

Stress and conflict in emergency departments are inevitable but can be managed. A supportive work environment is key to helping emergency care providers, especially nurses, constructively manage work-related stress and conflict.
The aim of this study was to assess the influence of supportive work environments on work-related stress and conflict management style among emergency care nurses.
A descriptive correlational research design was utilized. Data were collected from 221 staff nurses recruited from two university hospital emergency departments in Alexandria, Egypt. Three instruments were used: (1) perceived organizational support scale, (2) nurses' occupational stressors scale, and (3) conflict management style inventory.
There was a highly significant correlation between supportive work environments and work-related stress (p = .000) and a significant correlation between supportive work environments and conflict management style (p = .026). Supportive work environments had a significant inverse negative relationship with work-related stress experienced by nurses (p = .001) and accounted for 51% of variance in work-related stress. Meanwhile, supportive work environments had a significant positive relationship with conflict management styles of nurses (p = .026). Work-related stress had a significant relationship with nurses' conflict management style (p = .000) and accounted for 45% of the variance in conflict management style.
The style of conflict management modeled by staff within emergency departments can positively or negatively influence the work environment and level of work-related stress. There is a necessity to cultivate a supportive culture for nurses in emergency departments to develop skills for constructive conflict management styles to reduce work-related stress.

Since the coronavirus (COVID-19) outbreak in December 2019, students have been under unparalleled psychological stress worldwide. As part of its prevention and control strategies, the Chinese Ministry of Education proposed online teaching activities for universities. For the first time, teaching and learning shifted completely online, significantly impacting university students used to classroom learning. This research addresses the knowledge gap about the mental health and coping strategies employed by Chinese university students during the COVID-19 pandemic. Electronic databases (PsycINFO, Scopus, Medline, Cochranes and CNKI) were searched systematically from 2019 to 2023, as part of this literature review. From the 349 articles found, 25 met the inclusion criteria for analysis. Thematic analysis was used to identify six sub-themes, organized under two main themes: Mental health issues of Chinese university students and their coping mechanisms. Heightened stress, anxiety, and depression appeared in Chinese university students during the pandemic, which may have been compounded by their isolation and the disruptions to their studies. Although the impact of COVID-19 on Chinese university students is waning, this study emphasizes the potential long-lasting impact on their mental health, which requires further investigation, particularly regarding gender differences. Moreover, positive and negative coping strategies were found in this review. Strategies for seeking social and family support and participating in sports activities had significant alleviating effects, while negative coping strategies such as alcohol-use and smoking did not. This rapid review informs the development of policies and interventions to enhance the mental health of university students during crisis events. The findings serve to inform health policymakers, university psychologists, and educators in improving the well-being of this student population.by Divya Kumar, Waqas Hameed, Bilal Iqbal Avan
BackgroundMost empirically researched interventions for postpartum depression (PPD) tend to target mothers’ depression alone. Harmful effects of PPD on physical and mental health of both mother and child has led researchers to investigate the impact of interventions on PPD and child outcomes together. So far, the evidence is limited regarding how these interventions compare with those focusing only on mothers’ depression. This review compares the effectiveness of PPD-improving interventions focusing only on mothers with those focusing on mother and child together.
MethodsNine electronic databases were searched. Thirty-seven studies evaluating mother-focused (n = 30) and mother-child focused interventions (n = 7) were included. Under each category, three theoretical approaches—psychological, psychosocial and mixed—were compared using standardized qualitative procedures. The review’s primary outcome was maternal PPD.
ResultsA higher proportion of mother-focussed interventions [20/30 (66.7%)] brought significant reduction in PPD outcomes as compared to a lower proportion of mother-child focused interventions [4/7 (57.14%)]. Mother-focused mixed approaches [3/3 (100%)] performed better in improving PPD than psychological [16/24 (67%)] or psychosocial approaches [1/3 (33.3%)] alone. Amongst mother-child focused interventions, psychosocial approaches performed well with two-thirds demonstrating positive effects on PPD.
ConclusionThe evidence strongly favors mother-focused interventions for improving PPD with mixed interventions being more effective. Psychosocial approaches performed better with PPD once child-related elements were added, and also seemed best for child outcomes. Psychological approaches were most practiced and effective for PPD, irrespective of the intervention’s focus. Further trials are needed to unpack intervention components that improve PPD and increase uptake, especially in lower-and middle-income countries.

The quorum sensing mechanism relies on the detection and response to chemical signals, termed autoinducers, which regulate the synthesis of virulence factors including toxins, enzymes, and biofilms. Emerging therapeutic strategies for infection control encompass approaches that attenuate quorum-sensing systems. In this study, we evaluated the antibacterial, anti-quorum sensing, and anti-biofilm activities of Psidium guajava L. methanolic leaf extracts (PGME). Minimum Inhibitory Concentrations (MICs) of PGME were determined as 500 μg/ml for C. violaceum and 1000 μg/ml for P. aeruginosa PAO1. Significantly, even at sub-MIC concentrations, PGME exhibited noteworthy anti-quorum sensing properties, as evidenced by concentration-dependent inhibition of pigment production in C. violaceum 12742. Furthermore, PGME effectively suppressed quorum-sensing controlled virulence factors in P. aeruginosa PAO1, including biofilm formation, pyoverdin, pyocyanin, and rhamnolipid production, with concentration-dependent inhibitory effects. Phytochemical analysis utilizing GC-MS revealed the presence of compounds such as alpha-copaene, caryophyllene, and nerolidol. In-silico docking studies indicated a plausible mechanism for the observed anti-quorum sensing activity, involving favorable binding and interactions with QS-receptors, including RhlR, CviR’, LasI, and LasR proteins. These interactions were found to potentially disrupt QS pathways through suppression of AHL production and receptor protein blockade. Collectively, our findings propose PGME as a promising candidate for the treatment of bacterial infections. Its attributes that mitigate biofilm development and impede quorum-sensing mechanisms highlight its potential therapeutic value.by Muhammad Bilal Siddiqui, Chiu Wan Ng, Wah Yun Low, Khadijah Abid
The majority (40%) of the world’s under-five mortality burden is concentrated in nations like Nigeria (16.5%), India (16%), Pakistan (8%), and the Democratic Republic of the Congo (6%), where an undetermined number of under-five deaths go unrecorded. In low-resource settings throughout the world, the Verbal Autopsy-Social Autopsy (VASA) technique may assist assess under-five mortality estimates, assigning medical and social causes of death, and identifying relevant determinants. Uncertainty regarding missing data in high-burden nations like Pakistan necessitates a valid and reliable VASA instrument. This is the first study to validate Child Health Epidemiology Reference Group-CHERG’s VASA tool globally. In Pakistan, data from such a valid and reliable tool is vital for policy. This paper reports on the VASA tool in Karachi, Pakistan. Validity and reliability of the CHERG VASA tool were tested using face, content, discriminant validation, and reliability tests on one hundred randomly selected mothers who had recently experienced an under-five child death event. Data were computed on SPSS (version-21) and R software. Testing revealed high Item-content Validity Index (I-CVI) (>81.43%); high Cronbach’s Alpha (0.843); the accuracy of between 75–100% of the discriminants classifying births to live and stillbirths; and I-CVI (>82.07% and 88.98% respectively) with high accuracy (92% and 97% respectively) for assigning biological and social causes of child deaths, respectively. The CHERG VASA questionnaire was found relevant to the conceptual framework and valid in Pakistan. This valid tool can assign accurate medical and non-medical causes of child mortality cases occurring in Pakistan.by Hanem M. M. Mansour, Mohamed G. Shehata, Eman M.

Nanotechnology applications have been employed to improve the stability of bioactive components and drug delivery. Natural-based extracts, especially olive leaf extracts, have been associated with the green economy not only as recycled agri-waste but also in the prevention and treatment of various non-communicable diseases (NCDs). The aim of this work was to provide a comparison between the characteristics, biological activity, and gene expression of water extract of olive leaves (OLE), green synthesized OLE silver nanoparticles (OL/Ag-NPs), and OLE whey protein capsules (OL/WPNs) of the two olive varieties, Tofahy and Shemlali. The particles were characterized by dynamic light scattering, scanning electron microscope (SEM), and Fourier transform infrared. The bioactive compounds of the preparations were evaluated for their antioxidant activity and anticancer effect on HCT-116 colorectal cells as well as for their regulatory effects on cytochrome C oxidase (Cox1) and tumor necrosis factor α (TNF-α) genes. (OL/Ag-NPs) were found to be smaller than (OL/WPNs) with sizes of (37.46±1.85 and 44.86±1.62 nm) and (227.20±2.43 and 553.02±3.60 nm) for Tofahy and Shemlali, respectively. SEM showed that Shemlali (OL/Ag-NPs) had the least aggregation due to their highest Ƹ-potential (-31.76 ± 0.87 mV). The preparations were relatively nontoxic to Vero cells (IC50 = 151.94–789.25 μg/mL), while they were cytotoxic to HCT-116 colorectal cells (IC50 = 77.54–320.64 μg/mL). Shemlali and Tofahy OLE and Tofahy OL/Ag-NPs had a higher selectivity index (2.97–7.08 μg/mL) than doxorubicin (2.36 μg/mL), indicating promising anticancer activity. Moreover, Shemlali preparations regulated the expression of Cox1 (up-regulation) and TNF-α (down-regulation) on HCT-116 cells, revealing their efficiency in suppressing the expression of genes that promote cancer cell proliferation. (OL/Ag-NPs) from Tofahy and Shemlali were found to be more stable, effective, and safe than (OL/WPNs). Consequently, OL/Ag-NPs, especially Tofahy, are the best and safest nanoscale particles that can be safely used in food and pharmaceutical applications.by Rishan Hadgu, Ahmed Husen, Esayas Milkiyas, Niguse Alemayoh, Robel Zemoy, Azene Tesfaye, Dagimawie Tadesse, Aseer Manilal, Aklilu Alemayehu
BackgroundAnemia is a significant public health problem in HIV/AIDS patients worldwide. This study is aimed to determine the prevalence of anemia and its risk factors among HIV-infected adults in Sawla General Hospital, southern Ethiopia.
MethodsA facility-based cross-sectional study involving HIV-infected adults was conducted in ART clinic of Sawla General Hospital from April 01 to May 31, 2019. A systematic random sampling technique was employed to recruit the study participants. Socio-demographic and clinical data were collected using a structured questionnaire and checklist. Hemoglobin concentration from venous blood was determined by HemoCue® 301 analyzer. Descriptive and inferential statistics, by Statistical Package for Social Science version 26.0, were applied; p-values ≤ 0.05 in the multivariable logistic regression analysis were considered statistically significant.
ResultsA total of 220 HIV-infected adults participated in this study. The prevalence of anemia was 38.6%, from which 90.6, 7.1, and 2.3% are mild, moderate, and severe anemia, respectively. Anemia among HIV-infected adults was significantly associated with CD4 cell count below 200 cells/mm3 (AOR: 4.32; 95% CI: 2.10–8.86), clinical stage III or above (AOR: 4.20; 95% CI: 1.06–16.62), five or more years duration of HIV infection (AOR: 2.32; 95% CI: 1.08–4.94) and BMI below 18.5 kg/m2 (AOR: 3.82; 95% CI: 1.83–8.00).
