Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950-2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021

BACKGROUND

Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020-21 COVID-19 pandemic period.

METHODS

22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution.

FINDINGS

Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5-65·1] decline), and increased during the COVID-19 pandemic period (2020-21; 5·1% [0·9-9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98-5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50-6·01) in 2019. An estimated 131 million (126-137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7-17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8-24·8), from 49·0 years (46·7-51·3) to 71·7 years (70·9-72·5). Global life expectancy at birth declined by 1·6 years (1·0-2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67-8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4-52·7]) and south Asia (26·3% [9·0-44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations.

INTERPRETATION

Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic.

The Perceived Informational Needs of Family Caregivers of Children Hospitalized in a Burn Department: A Cross-sectional Study

Children are most vulnerable to burn injuries, and their families are their most important source of support. Therefore, it is necessary to identify the information needs of such parents and support them to help children adapt to the new situation, recover to pre-accident conditions, and reintegrate into school and society. This study aimed to investigate the perceived information needs of family caregivers of children admitted to the burn wards of hospitals. This cross-sectional study was conducted on 200 family caregivers of children admitted to the burn ward of a hospital in Tabriz, Iran. Participants were selected through convenience sampling, and the required data were collected by using questionnaires on socio-demographic information, information needs, information resources, and information acquisition methods. The obtained data were analyzed statistically using descriptive statistics (mean, standard deviation, frequency, and percentage) and inferential statistics (Mann-Whitney, Kruskal-Wallis, and Spearman correlation tests). Results indicated that the greatest informational need among family caregivers was related to the child's condition. The treatment team was identified as the most important source of information for them. It was found that information should be provided in a comprehensive and understandable manner, while maintaining honesty and human dignity. The study findings contribute to our understanding of the specific information needs of family caregivers in managing the medical care of children with burns. These findings can serve as a basis for interventions and support services aimed at meeting the needs of these families and improving the quality of care for children with burns.

Family-based education and follow-up program for patients with burns: A mixed assessment study

BACKGROUND

Burn injuries are a major cause of morbidity and mortality worldwide, affecting not only the patients but also their families. Family-based education and follow-up program are interventions that aim to improve the quality of life and psychosocial outcomes of patients with burns and their families. However, we find a lack of evidence on the effectiveness and feasibility of these programs in different settings and populations. This study aimed to evaluate the features of the family-based education and follow-up program (FBEFP), a pilot project that was developed and implemented at the Tabriz Sina Teaching Hospital in 2020 to improve its burn care system.

DESIGN

A mixed-methods approach was used to collect and analyze both quantitative and qualitative data from various sources, such as, questionnaires, medical records, interviews and observation notes, to assess the content, process, and outcome of the program. The study followed the three steps of the CDC's framework for program evaluation: describing the program, measuring its effectiveness, and providing recommendations for improvement.

RESULTS

The results of this study revealed the positive impacts of the FBEFP on the patients' physical, psychological, and social outcomes and quality of life. 4.8% of the people in the follow-up group were re-admitted, while this amount was 7.2% in the group without follow-up. Although the number of readmissions was less in the non-follow-up group, statistically no significant difference was observed between the two ratios before and after follow-up. In order to evaluate satisfaction rates, In the follow-up group, 72 patients and in the non-follow-up group, 38 patients were reached. After converting these data to normal distribution, using t-tests, it was determined that the difference between the two studied groups was highly significant. In other words, the follow-up process had favorable results on satisfaction of the studied people. However, the study also identified some challenges and barriers in implementing the program, such as lack of resources, staff training, and family involvement.

CONCLUSION

FBEFP is a promising intervention that enhances the well-being of patients with burns and their families. However, more evidence is needed to support its effectiveness and feasibility in different contexts and populations. The study also provided valuable insights into the benefits and challenges of implementing a Family-Based Education and Follow-up Program for patients with burns in a low-resource setting. The study contributed to the development of guidelines and recommendations for future research and practice in this field.

Virtual care in the health care system: A concept analysis

BACKGROUND

Health care providers need a better understanding of virtual care to recognise and use it for service delivery.

AIM

To provide a more comprehensive definition of the concept of virtual care.

METHOD

This study was conducted based on Walker and Avant's concept analysis method. A comprehensive review of the published texts in English from 2012 to 2022 was performed using the PubMed, Web of Science, Scopus, ProQuest, Science Direct, Ovid, CINAHL and Google Scholar databases.

RESULTS

The main aspects and attributes of virtual care, including the use of any information and communication technology in various formats such as platforms, telephone calls, messages, email consultation, remote monitoring, secure and two-way digital communication between health care providers and patients, the possibility of providing remote care synchronously or asynchronously, more interaction between patients and caregivers, the possibility of transferring information between patients and health care providers and within the teams themselves, symptom management, sending diagnostic results in the form of video visits, and providing follow-up care, are attributes that distinguish virtual care from telehealth, telemedicine and other methods of providing remote healthcare services.

CONCLUSION

Considering the positive and negative consequences of implementing virtual care, the findings of this study developed a basis for an operational definition of the concept so that providers can understand the meaning of virtual care and consider it when providing virtual care to patients. The findings of this study can be used in many international and national contexts in the health care system and in future studies on interventions to increase the use of virtual care.

Barriers to the implementation of virtual care programmes for patients with chronic wounds: Qualitative empirical research

AIM

To assess the barriers to the implementation of virtual care for patients with chronic wounds from wound therapists' perspective.

DESIGN

A qualitative study.

METHODS

The study was conducted in two consecutive phases: (1) literature review, (2) descriptive qualitative study. In the first phase, texts published in English until 2023 were identified using international databases. The entire text of the selected studies was evaluated independently by two reviewers. Data analysis was carried out using textual content analysis. In the second phase of the study, twelve participants from Iranian wound care clinics participated. Data were collected through focus group discussion and analysed using conventional content analysis. Integration of both phases was conducted in the data analysis stage.

RESULTS

The most important barriers in providing virtual care to patients with chronic wounds were identified into five categories including lack of policymaking in virtual care, ethical challenges in virtual information and communication technology, social, economic and cultural issues, IT users' insufficient knowledge and limitation of virtual care scope of practice.

CONCLUSION

The findings of the present study identified different barriers in the implementation of virtual care for patients with chronic wounds. In order to successfully develop a virtual care programme, it is necessary to adopt suitable policies regarding information and communication technology, provide the necessary legal frameworks, assign an adequate budget and consider the ethical, cultural, social and social issues.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Identifying barriers to developing a virtual care programme will help manage patients with chronic wounds at home.

IMPACT

This study accurately identifies barriers to providing virtual care for patients with chronic wounds and helps plan to address these barriers and facilitate the development of a virtual care programme for these patients at home.

An appropriate simulation-based training for surgical technology students

BACKGROUND

Using simulation in an appropriate education plan which has always been challenging; To be used alone or in combination with other methods and the order of it's use. This article was intended to compare student's knowledge, clinical skill and readiness-capability using simulation and combination of it with traditional training methods to collect necessary evidence for development of an appropriate simulation- based educational plan for surgical technology students.

METHODS

This is a controlled pre/post-test quasi-experimental study in 2019. All surgical technology students who had selected the scrub and circulate course (n = 28) were randomly divided into two groups. One of the groups was educated with traditional training method (TTM). On the same day, the other group was educated with simulation training method (STM). After two weeks, group α received simulation training and group β was subject to traditional training. Multiple-Choice Test for Knowledge Assessment and Clinical Skills as well as Readiness-Capability (KCSRC) of appendectomy Surgery checklist were used in this study. Data were analysed after each training method, after Two weeks and after blended education.For data analysis, Mixed-Design ANOVA and SPSS software 24/v were employed.

RESULTS

The mean scores of knowledge, clinical skills, and readiness-capability were 14.2 ± 2.91, 44.42 ± 17.74, 21.58 ± 4.18 in group α and 12.66 ± 3.21, 41.17 ± 16.19, and 18.58 ± 7.85 in group β, respectively. The comparison between mean scores of KCSRC before the first training and after combined training in each group showed that the mean of all scores significantly increased in group α (p < 0.0001), which indicates that the education plan starting with TTM and continued with STM has the most significant effect on results.

CONCLUSION

According to the results of the study, it seems that starting the education plan for surgical students with TTM and then continuing with STM would be more effective on education of students, especially on students' long term learning.

Cultural competence of nursing educators at medical universities of 2nd regional planning in Iran

BACKGROUND

One of the facets of nursing care, as a holistic profession, is cultural care. Considering the role of culture in individuals' health behaviors, nurses are recommended to be mindful of cultural care. Since nursing educators should be culturally competent to teach cultural care to students, this study aimed to determine the cultural competence of nursing educators of medical sciences universities in the 2nd regional planning in Iran.

METHODS

The current research was a descriptive and survey study framed within Campinha-Bacote's cultural competency model. All nursing educators of universities of medical sciences in the 2nd regional planning of Iran (Tabriz, Urmia, Ardabil, Khoy, Maragheh, Sarab, and Khalkhal) were considered as research units, and the cultural diversity questionnaire for nursing faculties (CDQNE-R) was sent to them. Out of 129 questionnaires sent, 84 were turned back. The data were analyzed by the SPSS 22 software.

RESULTS

The results of this study showed that the research participants agreed with the subscales of cultural awareness, cultural knowledge, cultural skill, and cultural desire according to Sealey and Yates' interpretation scale. Also, the research units cast doubts on the cultural encounter subscale. The mean scores of the participants' responses to the questions of every subscale equaled 4.11, 3.52, 3.71, 3.38, and 3.93 for the subscales of cultural awareness, cultural knowledge, cultural skill, cultural encounter, and cultural desire, respectively. Likewise, the mean scores of participants' responses to the subscales of transcultural educational behaviors and general cultural competence equaled 3.90 and 3.73.

CONCLUSIONS

The nursing faculties participating in the present study agreed with the 4 sub-models of Campinha-Bacote cultural care and the presence of cultural competence criteria. Also, the research units had doubts about the cultural encounter subscale. This result means that the research participants were undecided about their level of participation in face-to-face interactions with people from different cultural, racial, and ethnic groups. According to the results of the study, it is important to hold transcultural nursing training workshops and courses to maintain and improve the level of cultural competence of nursing faculties at universities of medical sciences in the 2nd regional planning in Iran.

The impact of institutionalizing the nursing process based on TPSN model on the quality and quantity of nursing diagnoses

AIM

Nursing diagnosis is the basis of applying nursing process and evidence-based care in nursing. This issue has been affected by the gap between theory-practice in nursing. The attending nursing teachers Project aims to create an organizational link between health care centres and nursing schools, reducing the gap between theory-practice and empowering nurses to apply nursing diagnosis.

DESIGN

The present study was part of the second cycle of an action research study conducted in the cardiology ward in 2019-2020.

METHODS

Interventions were performed in the form of Teacher, Patient, Student, Nurse Model to empower nurses in quantity and quality of nursing diagnosis.

RESULTS

The results indicated a significant increase in the number of nursing diagnoses recorded. Moreover, the qualitative criteria based on PES components were found to have changed significantly after the interventions. Empowering nurses in the form of this Project could suggest that creating proper structures between nursing schools and health care centres, full-time presence of faculty members in hospitals, and enhancing their roles in these institutes will lead to improvements in educational as well as health care systems.

A scoping review of virtual care in the health system: infrastructures, barriers, and facilitators

For virtual care models to be able to improve the safety and quality of care, it is essential to identify the strengths and weaknesses of virtual care. In this Scoping review, literature published on virtual care was identified using international databases. The results of the included studies were summarized using a predefined taxonomy. In total, 20 studies were included in the present review. Extracting the findings of the articles showed four main topics, including "virtual care delivery models," "Video conference software platforms to provide virtual care," "virtual care delivery challenges," and "virtual care implementation facilitators." Therefore, with the development of emerging digital technologies, unique opportunities to provide virtual care and improve the provision of health services have been created in the health care system worldwide. Multifunctional video conference software platforms using specific models for each scope of care practice should be considered.

Evaluation of the occurrence of venous thromboembolic events in COVID-19 outpatients

Introduction

Thrombotic events are present at higher rates among COVID-19 patients. Prophylactic use of parenteral anticoagulants during hospitalisation is recommended to reduce the risk of complications. In this context, the Tunisian Anticoagulation Survey in COVID-19 patient General Practice experience (TASC-GP) was conducted.

Objective

The evaluation of the incidence of venous thromboembolic events (VTE) and bleedings in COVID-19 patients treated in ambulatory.

Method

The TASC-GP is an observational, multicenter study included 3,383 patients from July to October 2021. The following up of patients was done 35 days after inclusion date with investigation of VTE and bleeding events. The four main enrolment criteria were: 1) age ≥ 18 years; 2) confirmed COVID-19 infection; 3) treated as an outpatient; 4) initiation of Rivaroxaban 10 mg/d. Patients were excluded if any of the following criteria applied: 1) the use of anticoagulant or thrombolytic drugs other than Rivaroxaban on admission or within days of admission; 2) the use of any dosage other than that specified in the study protocol.

Results

The mean age of the population was 51.6 ± 15.5 years with a sex ratio of 0.67, 30.7% of the population had hypertension, 23.4% were diabetic and 34.9% were obese. At least one cardiovascular comorbidity was observed in 40% of cases and 9.5% had chronic respiratory disease. The mean IMPROVE and IMPROVE DDimer scores were 0.65 ± 0.9 and 1.4 ± 1.4, respectively. The mean Improve bleeding score was 1.4 ± 1.5. A VTE was reported during follow-up in 39 patients (1.15%). Diabetes and chronic respiratory disease were independent factors for the occurrence of VTE with an odd ratio of 2.2 [95% CI 1.1–4.2] (P = 0.017) and 3.2 [95% CI 1.5–6.4] (P = 0.002) respectively. IMPROVE and IMPROVE DDimer scores were comparable in patients with and without VTE. There was no statistically significant increase in the rate of major bleeding (0.001%). The IMPROVE Bleeding score was comparable in the bleeding and non-bleeding groups at follow-up. There were no predictive factors for bleeding.

Conclusion

Our study is in agreement with the literature concerning a decrease in the rate of thrombembolic complications when using prophylactic anticoagulation versus placebo. Other VTE estimation scores including chronic respiratory disease and diabetes can be proposed. The use of Rivaroxaban in this population was not associated with increased bleeding.

Age-sex differences in the global burden of lower respiratory infections and risk factors, 1990-2019: results from the Global Burden of Disease Study 2019

BACKGROUND

The global burden of lower respiratory infections (LRIs) and corresponding risk factors in children older than 5 years and adults has not been studied as comprehensively as it has been in children younger than 5 years. We assessed the burden and trends of LRIs and risk factors across all age groups by sex, for 204 countries and territories.

METHODS

In this analysis of data for the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we used clinician-diagnosed pneumonia or bronchiolitis as our case definition for LRIs. We included International Classification of Diseases 9th edition codes 079.6, 466-469, 470.0, 480-482.8, 483.0-483.9, 484.1-484.2, 484.6-484.7, and 487-489 and International Classification of Diseases 10th edition codes A48.1, A70, B97.4-B97.6, J09-J15.8, J16-J16.9, J20-J21.9, J91.0, P23.0-P23.4, and U04-U04.9. We used the Cause of Death Ensemble modelling strategy to analyse 23 109 site-years of vital registration data, 825 site-years of sample vital registration data, 1766 site-years of verbal autopsy data, and 681 site-years of mortality surveillance data. We used DisMod-MR 2.1, a Bayesian meta-regression tool, to analyse age-sex-specific incidence and prevalence data identified via systematic reviews of the literature, population-based survey data, and claims and inpatient data. Additionally, we estimated age-sex-specific LRI mortality that is attributable to the independent effects of 14 risk factors.

FINDINGS

Globally, in 2019, we estimated that there were 257 million (95% uncertainty interval [UI] 240-275) LRI incident episodes in males and 232 million (217-248) in females. In the same year, LRIs accounted for 1·30 million (95% UI 1·18-1·42) male deaths and 1·20 million (1·07-1·33) female deaths. Age-standardised incidence and mortality rates were 1·17 times (95% UI 1·16-1·18) and 1·31 times (95% UI 1·23-1·41) greater in males than in females in 2019. Between 1990 and 2019, LRI incidence and mortality rates declined at different rates across age groups and an increase in LRI episodes and deaths was estimated among all adult age groups, with males aged 70 years and older having the highest increase in LRI episodes (126·0% [95% UI 121·4-131·1]) and deaths (100·0% [83·4-115·9]). During the same period, LRI episodes and deaths in children younger than 15 years were estimated to have decreased, and the greatest decline was observed for LRI deaths in males younger than 5 years (-70·7% [-77·2 to -61·8]). The leading risk factors for LRI mortality varied across age groups and sex. More than half of global LRI deaths in children younger than 5 years were attributable to child wasting (population attributable fraction [PAF] 53·0% [95% UI 37·7-61·8] in males and 56·4% [40·7-65·1] in females), and more than a quarter of LRI deaths among those aged 5-14 years were attributable to household air pollution (PAF 26·0% [95% UI 16·6-35·5] for males and PAF 25·8% [16·3-35·4] for females). PAFs of male LRI deaths attributed to smoking were 20·4% (95% UI 15·4-25·2) in those aged 15-49 years, 30·5% (24·1-36·9) in those aged 50-69 years, and 21·9% (16·8-27·3) in those aged 70 years and older. PAFs of female LRI deaths attributed to household air pollution were 21·1% (95% UI 14·5-27·9) in those aged 15-49 years and 18·2% (12·5-24·5) in those aged 50-69 years. For females aged 70 years and older, the leading risk factor, ambient particulate matter, was responsible for 11·7% (95% UI 8·2-15·8) of LRI deaths.

INTERPRETATION

The patterns and progress in reducing the burden of LRIs and key risk factors for mortality varied across age groups and sexes. The progress seen in children younger than 5 years was clearly a result of targeted interventions, such as vaccination and reduction of exposure to risk factors. Similar interventions for other age groups could contribute to the achievement of multiple Sustainable Development Goals targets, including promoting wellbeing at all ages and reducing health inequalities. Interventions, including addressing risk factors such as child wasting, smoking, ambient particulate matter pollution, and household air pollution, would prevent deaths and reduce health disparities.

An introduction to the TPSN model: a comprehensive approach to reducing the theory-practice gap in nursing

Background

There are still concerns about the effectiveness of clinical education models which are done with the aim of reducing the theoretical-practical gap in nursing. In this article, we intend to describe an innovative model to create an integration and structured relationship between educational and healthcare provider institutions. The basis of this work is the full-time presence of nursing teacher in the clinical settings and the development of their role to improve the education of students and nurses and the quality of nursing services.

Methods

This was a participatory action research. This action research was implemented in four steps of problem identification, planning, action and reflection. Interviews, focus groups and observation were used for the qualitative part. Clinical Learning Environment Inventory (CLEI), Job Satisfaction in Nursing Instrument questionnaires and Patient Satisfaction with Nursing Care Quality Questionnaire were completed before and after the study. Qualitative content analysis, paired and independent t test were used for data analysis.

Results

The academic-practice integration Model of TPSN is a dynamic and interactive model for accountability in nursing Discipline. Unlike the medical education model that includes patients, students, and physicians as the three points of a triangle, this model, which is shaped like a large triangle, places the person in need of care and treatment (patient, client, family, or society) in the center of the triangle, aiming to focus on the healthcare receiver. The model consists of three components (Mentoring component, Preceptorship component, and integrated clinical education component). Each of the components of this model alone will not be able to eliminate the ultimate goal of bridging the theory-practice gap.

Conclusions

A new and innovative model was proposed to reduce the theory-practice gap in the present study. This model increases the collaboration between educational institutions and healthcare settings compared with the previous models. The TPSN model helps students, nurses, and nursing instructors integrate theoretical knowledge with clinical practice and act as professional nurses.

The global burden of cancer attributable to risk factors, 2010-19: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally.

METHODS

The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented.

FINDINGS

Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01-4·94) deaths and 105 million (95·0-116) DALYs for both sexes combined, representing 44·4% (41·3-48·4) of all cancer deaths and 42·0% (39·1-45·6) of all DALYs. There were 2·88 million (2·60-3·18) risk-attributable cancer deaths in males (50·6% [47·8-54·1] of all male cancer deaths) and 1·58 million (1·36-1·84) risk-attributable cancer deaths in females (36·3% [32·5-41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6-28·4) and DALYs by 16·8% (8·8-25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9-42·8] and 33·3% [25·8-42·0]).

INTERPRETATION

The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Exploring Barriers to the Development of Home Health Care in Iran: A Qualitative Study

Changes in society’s needs have increased individuals’ desire to be independent and receive health care at home. Home health care (HHC) is one of the main components of realizing these ambitions. However, there is a serious concern about the state of development of the HHC industry in Iran and the quality of its services. This study aims to explore the barriers to the development of HHC in Iran. This qualitative study with a conventional content analysis approach was conducted in Tabriz, Iran, from October 2019 to March 2020. Twenty-one key stakeholders including nurses, home health directors, physicians, policy-makers, patients, and their families participated in the study. Participants were selected using purposive sampling. Data were collected using a focus group discussion (FGD) and 18 semi-structured in-depth interviews and analyzed using Graneheim and Lundman’s techniques. Data collection continued until saturation was reached. Three main themes emerged from the analysis: quality management challenges, insufficient infrastructure and policy, and political issues. The findings show that applying standard strategies to monitor the quality of services, paying attention to infrastructure, and having a clear framework for policy-making are beneficial for the development of the HHC industry. Health managers can monitor and upgrade the quality of HHC services by defining standards and assessment indicators, as well as providing comprehensive data. It is suggested that legislators consider the principles of community-based accountability, justice, and accessibility their top priority. Moreover, policymakers need to develop a roadmap to reform policies to create the conditions for the development of this industry.

Turnover intention among operating room nurses during the COVID-19 outbreak and its association with perceived safety climate

Background

In critical situations such as the COVID-19 pandemic, nurses always face a lot of stress that can increase their turnover intention. Since a suitable safety climate in the workplace is considered an important factor in preventive management of occupational hazards and people's adaptation to stressful conditions, the present study aimed to determine Turnover intention among operating room nurses during the COVID-19 outbreak and its association with perceived safety climate.

Methods

In this descriptive correlational study, participants were 190 operating room nurses working at public hospitals in Mazandaran (Iran) who were selected by stratified random sampling. Data were collected using the Anticipated Turnover Scale and the Nurses' Safety Climate Questionnaire and analyzed using SPSS16.

Results

The results of the linear regression analysis revealed that safety climate significantly reduced turnover intention among nurses in the COVID-19 pandemic (P < 0.001). An increase of one unit in the total score of safety climate led to a 0.6 reduction in the turnover intention of operating room nurses.

Conclusion

The present findings demonstrated an unfavorable safety climate perceived by perioperative nurses in the COVID-19 pandemic, with a significant inverse relationship with turnover intention. Strategies such as training personnel on the prevention of the disease transmission in the surgery of patients infected with or suspected of COVID-19, creating a proper supportive environment for personnel, and providing appropriate protective equipment to prevent infection with COVID-19 seem absolutely vital to improving the safety climate in the operating room, thereby reducing turnover intention.

Attitude, preventive practice and perceived barriers among perioperative and anesthesia nurses toward surgical smoke hazards during the COVID-19 outbreak

Background

Surgical smoke (SS), which is produced by the use of high-temperature devices for cutting and coagulation of tissue during surgical procedures, is considered a serious threat to the health of operating room (OR) staff due to the presence of hazardous substances and possibility of transmitting various infections such as HPV, HIV, COVID-19 and so on. This study was conducted to determine the Attitude, preventive practice and perceived barriers among perioperative and anesthesia nurses toward surgical smoke hazards.

Methods

In this cross-sectional descriptive study, conducted at hospitals of Tabriz University of Medical Sciences (Iran) in 2021, 262 perioperative and anesthesia nurses were included by stratified random sampling. Data were collected using a demographic questionnaire and an SS questionnaire consisting of questions on attitude (17 item), practice (8 item), and barriers (13 item). Collected data were analyzed using SPSS16.

Results

The mean attitude and preventive practice scores (49.52 ± 12.36 and 15.8 ± 2.05, respectively) of the operating room nurses were reported at moderate and weak levels, respectively. There was a direct and significant relationship between attitude and practice scores (r = 0.129, P = 0.019). The main barriers to the prevention and dealing with the hazards of SS in ORs were reported in management (3.68 ± 1.06) and equipment (3.24 ± 0.66) dimensions, respectively.

Conclusion

It is recommended to adopt strategies to improve the attitude of OR staff regarding the preventive measures against surgical smoke hazards. Moreover, appropriate equipment and support of managers should be provided by explaining the policies and guidelines to prevent the complications of surgical smoke.

Cultural Factors and Social Changes Affecting Home Healthcare in Iran: A Qualitative Study

In Iran, home healthcare (HHC) is provided in a diverse socio-cultural context. Health professionals’ inadequate knowledge of the socio-cultural factors of the society can lead to poor quality HHC. Even so, the ways these factors influence HHC remain unclear. This study aimed to explore the effects of cultural factors and social changes on HHC in Iran. This qualitative study which follows a conventional content analysis approach was conducted in Tabriz, Iran. Eighteen individuals including nurses, home health directors, physicians, policy-makers, patients, and their families participated in the study. Participants were selected using purposive sampling. Data collection involved focus group discussion (FGD) and 16 semi-structured in-depth interviews. In order to analyze the data, Graneheim and Lundman’s techniques were used and data collection continued until saturation was reached. Five main themes emerged from the data analysis including cultural diversity issues, society’s understanding of HHC, shifting demographics affecting healthcare needs, transitioning from traditional to modern lifeways, and increasing unaffordability of healthcare. Health managers can improve the accessibility and acceptability of HHC services by identifying the socio-cultural needs of the society. Future research should develop and test patients and families’ cultural care models in the HHC setting.

Disaster preparedness and core competencies among emergency nurses: A cross-sectional study

Aim

With the rise in frequency and severity of disasters in recent decades, it is essentially important that nurses must be adequately prepared to handle them. This study was aimed to evaluate the levels of disaster core competencies and preparedness of nurses in the emergency department.

Design

A cross‐sectional survey design was used.

Methods

This cross‐sectional research was conducted from August 2020 to December 2020 among 271 nurses in the emergency departments of six hospitals in Qazvin, Iran. The participants completed the “Nurses Perceptions of Disaster Core Competencies Scale” (NPDCC) (45 items) and the disaster preparedness (a single‐item visual scale). Data were analysed by one‐way analysis of variance, independent t‐tests and multiple linear regression analysis.

Results

The mean scores of disaster preparedness and core competencies of nurses were 6.75 out of 10 (SD = 1.63) and 2.88 out of 5 (SD = 0.80), respectively. "Technical skills" (mean = 3.24, SD = 0.91) were the highest and "communication skills" (mean = 2.57, SD = 0.95) were the lowest across the subscales of the scale. A significant association was found between disaster core competencies and preparedness of nurses (p < .001). Regression analysis results indicated that nursing disaster core competencies were perceived betted by older nurses (B = −0.405) who had experience in the disaster stage (B = 0.228) and nurses with disaster response experience (B = 0.223) and lower professional experience (B = 0.309). Nurses with a postdiploma degree (B = −0.480) and bachelor's degree (B = −0.416) were perceived to have lower disaster core competency than nurses with a master's or PhD degree.

Conclusion

There are still gaps in disaster preparedness and core competencies for emergency nurses that need to be addressed. Nursing managers must support an improvement in nursing disaster core competencies. This may be done by conducting sessions for routine disaster scenarios and providing formal disaster preparedness training.

Caring Needs of Cancer Patients from the Perspective of Home Care Nurses: A Qualitative Study

Objective:

Cancer is the third leading cause of death in Iran. Todays, caregiving to patients with cancer is shifting towards home based care, and home care needs from a caregiver’s perspective can help improve the patient care. This qualitative study aimed to examine the home care needs of cancer patients from the perspective of home care nurses.

Methods:

This is a qualitative descriptive study carried out at home care centers in the northwest of Iran. A total of 15 participants were recruited through purposive sampling and underwent face-to-face semi-structured interviews. Data were analyzed through Conventional content analysis method in MAXQDA software. Measures of trustworthiness were established throughout the study using Lincoln and Guba’s (1985) criteria (dependability, credibility, transferability, and confirmability).

Results:

Data analysis resulted in the extraction of four main categories including physical needs (pain relief, gastrointestinal problems including nausea and anorexia and nutritional problems, lethargy, wound care), psychological support (need for hope and emotional support), educational needs (need for information and self-care) and financial support (service insurance coverage, charity support). To promote these patients home care, insurance coverage of nursing home care services was emphasized by the participants.

Conclusion:

Various aspects of cancer patients home care needs were identified. Interdisciplinary home-based palliative care collaboration is needed to address their physical, psychological, and moral needs.

Measuring Staff Satisfaction in Transportation System using AHP Method under Uncertainty

One of the most important challenges in today world is the transportation and satisfaction of this system. Measuring satisfaction in transportation has been done quantitatively so far and, more importantly, the measurement process has not usually been scientific. This study aimed at an accurate scientific measurement. Because of ambiguity, this paper discusses how to use the intuitionistic fuzzy method, in which both membership and non-membership functions were expressed. Therefore, initially, considering the results of previous researches, as well as studying the references and standards, the characteristics and basic criteria, a researcher-made questionnaire with a reliability of 0.95 was first performed and then the weights were determined using the AHP intuitionistic fuzzy method. After performing the above steps, the intuitionistic fuzzy satisfaction value was calculated at different levels and using the method, the final number of satisfaction was defuzzified.

Burn self-stigma: A hybrid concept analysis

AIM

As burn self-stigma has not been addressed fully, the purpose of current study is to analyze dimensions of the concept using literature and lived experiences in burn survivors.

METHODS

Using hybrid concept analysis method, we investigated self-stigma in three phases (i.e. theoretical, fieldwork, and final analytical phase). In the first phase we reviewed the literature using PubMed, SCOPUS, Web of Science, Cochrane Library, OVID, SID and Google Scholar. Thirteen semi-structured interviews with burn survivors were conducted during the fieldwork phase. Two extra interviews with health care providers were undertaken for the aim of data triangulation. Textual content analysis and inductive content analysis were used to analyze the data of the first and second phases of this study, respectively. The findings of both phases were combined in the final analytical phase and a comprehensive definition was emerged.

RESULTS

We assigned all our findings into three content areas (i.e. antecedents, properties and consequences), which are dimensions of self-stigma. In final analytical phase antecedent, properties and consequences of the concept were formed in one (society's misconception about burns), three (negative definition of self, emotional responses, and behavioral responses), and three (negative individual effects, negative social effects, and negative familial effects) categories, respectively. Based on these categories and their corresponding subcategories, a comprehensive definition of the concept was presented.

CONCLUSION

Burn self-stigma is a state in which burn survivors experience unfavorable thoughts and feelings about themselves as a result of society's misconceptions about them. They give emotional and behavioral responses that define them in a negative way. In the end, the burn survivor's individual, familial, and social dimensions are significantly impacted.

A Comparative Study of the Impacts of Aloe vera Gel and Silver sulfadiazine Cream 1% on Healing, Itching and Pain of Burn Wounds: A Randomized Clinical Trial

Abstract Introduction: Although several studies have highlighted the beneficial effects of Aloe vera on burn wounds, limited clinical evidence exists in this regard. This study aimed to evaluate the impact of the Aloe vera gel on healing, itching and pain of burn patients. Methods: This clinical trial was conducted at Sina Hospital in Tabriz, Iran. The patients with second and first degree burn wounds on symmetrical organs, were randomly assigned to control (n=34) and experimental (n=34) groups. The Aloe vera gel and Silver sulfadiazine cream were used in the experimental and control groups, respectively. To assess the healing effects, the Bates-Jensen Wound Assessment Tool was employed. Regarding itching and pain, Visual Analogue Scale was used for precise evaluation and comparison on days 1, 3, 5, 7, 9 and 14. The data were analyzed using SPSS version 13. Results: Although the wounds in both groups healed up completely within two weeks, the healing process among the patients in the experimental group was faster. The peak of wound itching was on day 7 in both groups. The wound itching significantly reduced half an hour after being dressed with Aloe vera gel. The wound pain in the experimental group was less than control group during the study period. Moreover, there was no pain in either experimental or control group on day 14. Conclusion: Aloe vera is an effective agent in reducing itching and pain, and it can substantially increase the rate of healing. Accordingly, this agent can be considered in the treatment of burn wounds.

Preparation of an Inactivated Peste des Petits Ruminants Vaccine and Its Comparative Immunogenicity Evaluation in an Animal Model

Peste des petits ruminants (PPR) is a highly contagious disease that is considered a major threat to the small livestock industry. Although vaccination via live-attenuated PPR vaccine is a main controlling strategy in the endemic area, during PPR eradication process, the inactivated PPR vaccine (iPPRV) is recommended. This study aimed to compare the inactivation kinetics of the PPR virus via different inactivants and immunogenicity evaluations of the iPPRV formulated vaccine in mice. The vaccinal live PPR virus was inactivated by either H2O2 or binary ethylenimine (BEI (at two concentrations of 1 or 4 mM. Thereafter, the inactivated virus was formulated with different adjuvants, including aluminum hydroxide (AH), aluminum phosphate (AP), and a mixture of AH and AP that were intraperitoneally (IP) administrated (0.1 mL) to 90 BALB/c mice in a completely randomized design and 3×3 factorial arrangement (9 animals per group). The booster vaccination was carried out in all animals 21 days after the primary vaccination. Results showed that the PPR virus was successfully inactivated by all the inactivation agents; however, the time of complete virus inactivation was estimated to be 482, 295, and 495 min post-treatment initiation for 1 mM BEI, 4 mM BEI, and H2O2, respectively. The main effect of inactivant on antibody titers against PPR virus that was measured after 42days post-immunization in mice was significant (P<0.05); however, the adjuvant and interaction effect of inactivator×adjuvant were not effective(P>0.05). Inactivation by 1 mM BEI was associated with a higher antibody titer against PPR virus (P<0.05) in comparison with both 4 mM BEI and H2O2 (2.51 vs. 2.25 and 2.22, respectively). Meanwhile, there were no significant differences among the used adjuvants in terms of eliciting antibody response against PPR virus. In conclusion, the use of 1 mM BEI in combination of AH, AP, or a mixture of AH and AP was associated with a higher immune response against PPR virus in mice. However, the appropriate inactivation kinetic of the virus and immunogenicity associated with the use of H2O2, as well as its biocompatibility property and better cost-benefit, nominated H2O2 to be used in iPPR preparation; however, more investigations are required in target animals.

Society, family, and individual characteristics as double-edged swords in the social reintegration of Iranian female survivors from unintentional severe burns: a qualitative study of enablers and barriers

Background

Reintegrating to society is a significant challenge during burn survivors’ rehabilitation.

Aim

This study aims to describe what Iranian female survivors from unintentional severe burns experience as enablers and barriers of social reintegration (SR).

Methods

Fourteen adult female burn survivors whose burns were unintentional participated in this qualitative study. Data were gathered through semi-structured face-to-face or telephone interviews and analyzed using inductive content analysis.

Results

Thirteen subcategories and six categories were emerged. Categories and subcategories of enablers content area were as follows: positive impact of society on SR (normal treatment of society, instrumental support), positive impact of family on SR (magnifying personal abilities assets, empathy and emotional support), and positive impact of personal characteristics on SR (coping with others stares, right to have a normal social life). Categories and subcategories of Barriers content area were as follows: negative impact of society on SR (being questioned in public, incorrect judgment about intent of burns, burns as a contagious disease), negative impact of family on SR (embarrassment of appearing in public with the survivor, family mistrust), and negative impact of intra-personal factors on SR (exaggeration of the post-burn changes, being over-sensitive to the others looks). From the deep interpretation of the data two overarching themes were emerged: “acceptance of the new normal by the society and the individual” and “being encompassed by misconceptions and mistreatments”.

Conclusions

Society, family and the individual characteristics have a dual role to play in the success of social reintegration in Iranian female unintentional burn survivors.

Development and Evaluation of an Indirect Capripoxvirus ELISA Based on Truncated P32 Protein Expressed in E. coli

As notifiable diseases, lumpy skin disease (LSD), sheep pox (SPP), and goat pox (GTP) are associated with a profound effect on cattle, sheep, and goat farming industries. Development of the ELISA method could effectively facilitate serodiagnosis of the infected animals. This study aimed to develop an ELISA system based on the recombinant full-length and truncated P32 protein (Tr.P32) of goat pox virus. The P32 protein was expressed in Rosetta strain of E. coli using pET24a⁺ vector and evaluated by SDS-PAGE and Western blotting. Then, Tr.P32 was purified by Ni-NTA affinity chromatography under denaturing conditions and used to develop a capripoxvirus-specific ELISA. Checkerboard titration and receiver-operating characteristic (ROC) analysis were used to optimize the ELISA system and determine diagnostic specificity and sensitivity, respectively. The diagnostic potential of the developed ELISA was evaluated using positive and negative control sera collected from goat, sheep, and cattle. Results showed that the expression level of full-length P32 recombinant protein was negligible, while Tr.P32, a ~ 31 kDa recombinant protein, was expressed up to 0.270-0.300 mg/200 mL of culture media. The results of checkerboard titration revealed that 675 ng/well of Tr.P32 antigen and 1:10 dilution of control sera (anti GTPV HIS and healthy goat sera) caused maximum difference in absorbance between positive and negative goat sera. The recombinant Tr.P32 showed good reactions with antibodies against GTP virus (GTPV), SPP virus (SPPV), and LSD virus (LSDV), whereas no cross-reactions with anti-Orf virus antibodies were detected. By comparing with the neutralization index (NI), cut off, diagnostic sensitivity and specificity of the developed indirect-ELISA were estimated, 0.397, 94% and 96.6%, respectively. These findings indicate that the ELISA system based on Tr.P32 protein could potentially be used in sero-surveillance of all capripoxviruses; however, further investigations are required.

Observance of preventive standards against COVID-19 transmission in operating rooms: A cross-sectional study

Background

Due to the highly contagious innate of the novel coronavirus, the surgical team is exposed to the disease during surgical care of patient with confirmed covid-19. Therefore, the necessary measures should be taken to protect surgical caregivers. This study was conducted to determine the status of compliance with the preventive standards against covid-19 transmission in the operating room.

Methods

This cross-sectional descriptive study was conducted on 183 surgical team members working in hospitals affiliated to Tabriz university of medical sciences in 2020. Participants were selected by stratified random sampling. The required data were collected by a researcher-made questionnaire according to the standard protocols of SAGES, EAES and AORN. In the first part of this questionnaire, the level of compliance with the standards of using personal protective equipment (PPE) was evaluated and in the second part, the level of compliance with the preventive strategies in the operating room was evaluated in three phases of Pre, Intra and Post-operative. The data was analyzed using SPSS16.

Results

preventive standards observance against COVID-19 was in moderate (55.3 ± 10.5) level and The level of compliance with the standards of using PPE by the surgical team was favorable (61.8 ± 8.1). There was a statistically significant relationship between the level of compliance with the standards of using PPE and the type of specialty (P = 0.004).

Conclusion

According to the results, the level of compliance with the principles of standards in applying protective measures against covid-19 was not favorable, so the operating room personnel is exposed to COVID-19 and the necessary measures and improvements should be considered in compliance with standards in operating room.

The impact of a structured handover checklist for intraoperative staff shift changes on effective communication, OR team satisfaction, and patient safety: a pilot study

Objective

Handover without a structured format is prone to the omission of information and could be a potential risk to patient safety. We sought to determine the effect of a structured checklist on the quality of intraoperative change of shift handover between scrubs and circulars.

Methods

We conducted a control intervention study on operating room wards of two teaching hospitals from 20 Feb to 21 Nov 2020. This research was conducted in three stages as follows: assessing the current situation (as a group before the intervention), performing the intervention and evaluating the effect of using a checklist on handover quality after the intervention in two groups: with and without checklist. We examined the quality of handover between scrub and circular personnel in terms of handover duration and quality, omission of information and improvement in OR staff satisfaction.

Results

A total of 120 handovers were observed and evaluated. After intervention in the group using the checklist, the percentage of information omission in surgical report was decreased from 19.5 to 12.1% between scrubs (P < 0.00) and from 16.8 to 14.1% between circulars (P < 0.03). Also, in the role of scrub, the mean overall score of handover process quality was significantly higher after the intervention (x̄ = 7 ± 1.5) than before it (x̄ = 6.5 ± 0.9) (p < 0.02). In the role of circulating, despite the positive effect of overall score checklist, no significant difference was observed (p < 0.08). The use of checklist significantly increased the handover duration between scrubs (p < 0.03) and circulars (p < 0.00). The overall mean percentage of handover satisfaction increased from 67.5% before the intervention to 85.5% after the intervention (p < 0.00).

Conclusion

The implementation of a new structured handover checklist had a positive impact on improving the quality of communication between the surgical team, reducing the information omission rate and increasing the satisfaction.

Identification of Iranian BHK-21-C5 Cell Line by Two Steps Polymerase Chain Reaction

Authentication of animal cell lines in cell banks is one of the most important programs regulated during cell culture and storage. This operation provides a thorough and beneficial document which can be advantageous for the functional use of animal cell lines. Therefore, various procedures are used to prevent misidentified cells, cross-contamination to other cell lines, and mislabeling errors leading to incorrect assessment. These contaminants can result in major financial disadvantages. One of the practical methods in this field is a molecular procedure which can demonstrate more accurate results. In the present study, the BHK-21 (C5) was characterized, and it was tried to determine the identity of BHK-21 (C5) as a continuous cell line by Polymerase chain reaction (PCR) molecular procedure in Iran. The cytochrome c oxidase I (CO1) gene was selected as a prevalent DNA fragment for the authentication of the BHK-21 (C5) cell line, along with six cell lines, including Chinese hamster ovary, Lamb kidney, Razi Bovine Kidney, Medical Research Council cell strain 5, Monkey Green Kidney, and Goat Lymphocyte. After amplification, PCR products were analyzed by agarose gel electrophoresis to ensure their accuracy. The results of characterization were indicated, cell viability was estimated to be about 92%, and a uniform cell culture was obtained. The doubling time and &amp;micro; ratio equivalent were obtained at 20.5 h and 0.03, respectively. Sterility tests revealed that the cell seed was free of bacterial, mycoplasma, and mycobacterial infections. The results of molecular identification revealed that the identification of this cell line was approved and can be used in studies, diagnosis, production, and quality control of biological products.

The risk of surgery-related pressure ulcer in diabetics: A systematic review and meta-analysis

Background and objective

Postoperative pressure ulcers are known as the most important quality indicators of intraoperative care that create critical and costly complications during hospital care. Accordingly, this study was performed to determine the risk factor for diabetes in postoperative pressure ulcers.

Materials and methods

The present study is a systematic review of PubMed, Scopus and the Web of Science databases with using standardized keywords of the performed English language articles between Jan 2010 to Jan 2020. The articles were searched independently by two related researchers to avoid possible biases. Then, all collected articles were reviewed, and articles with inclusion criteria were evaluated using a data collection table. It should be noted that the data were analyzed using STATA software version 11.1.

Results

Overall, the results showed that 19724 patients were identified from 15 studies conducted in Asia (six), the America (four), Europe (four), and Australia (one) from 1989 to 2019. The results showed that patients with diabetes were more likely to experience surgery-related pressure ulcers than patients without diabetes (The odds ratio of 1.52; the 95% confidence interval: 1.25–1.85).

Conclusion

In general, patients with diabetes increased the risk of surgery-related pressure ulcers about 1.5 times more than others. Accordingly, the reduction of surgery-induced pressure ulcers should be more extensively considered in patients with diabetes.

What is already known about the topic?•

Diabetes as a preoperative comorbidity should be added to risk assessment instruments for perioperative pressure ulcers, which may increase the accuracy of the prediction.

•

The excess risk of pressure ulcers associated with pre-existing diabetes was significantly higher in patients undergoing surgery, specifically in patients receiving cardiac surgery.

What this paper adds.•

Diabetes increases the risk of surgery-related pressure ulcers about 1.5 times. Therefore, it is necessary to provide Planned Cares to prevent, overcome, and decrease surgery-related pressure ulcers in patients with diabetes.

•

Previous meta-analysis reported that the risk of surgery-related pressure ulcers in diabetic patients was higher than non-diabetic patients in cardiac surgeries, while evidence for this claim was not observed in this study. Considering the long duration of liver resection surgery, the risk of pressure ulcers is higher than heart surgery

•

It is advised that standard wound measuring tools will apply for measuring wounds in the next prospective studies. It is also better to evaluate pressure ulcers at a specific time after surgery toward more carefully investigate the issue.

Nursing process from theory to practice: Evidence from the implementation of "Coming back to existence caring model" in burn wards

Aim

To develop the caring model and utilize and evaluate the effect of the model in the nursing student's learning process in burn wards.

Design

A longitudinal multiphase study.

Methods

In the first phase, "Coming back to existence caring model" was developed, in the second phase, to evaluate the program, 35 students in the first semester and 31 students in the second semester of the 2017–2018 academic year were selected randomly, and their logbooks were analysed.

Results

Components of the nursing process, based on the model, were wound management, care and documentation, early mobilization, discharge planning and patient education. The lowest nursing process utilization in both semesters was in the sexuality domain. The most nursing diagnosis was a risk for infection. In the discharge plan, education about how the patient communicates with others in the second semester was less than other educational content (61/3%). However, empowering students was remarkable.

Frequency and risk factors of pressure injuries in clinical settings of affiliated to Tabriz University of Medical Sciences

AIM

Pressure injuries are considered a common and costly problem in the care of patients. Prevention and identification of risk factors for pressure injuries are very important due to the high cost of treatment and the adverse consequences of pressure injuries. This study aimed to assess the prevalence of pressure injuries and its risk factors in clinical settings of affiliated to Tabriz University of Medical Sciences.

DESIGN

A descriptive-analytical study.

METHODS

This study was performed on 200 patients who were selected by random sampling. The data collection tool was a 3-part questionnaire. Data were analysed using a t test, chi-square, Fisher's exact test and logistic regression in SPSS v. 24.

RESULTS

The mean age of the participants was 51.93 (SD 14.99) years. The rate of pressure injuries in this study was 19.5%. The most susceptible area for pressure injuries were sacral (35.89%) and gluteal (20.51%), respectively. The pressure injuries was significantly associated with Braden's criteria, age, disease diagnosis and length of hospital stay (p < .05). But there was no statistically significant difference between sex and incidence of pressure injuries (p > .05).

Phylogenetic analysis of canine parvovirus 2 subtypes from diarrheic dogs in Iran

BACKGROUND

Canine parvovirus type 2 (CPV-2) causes gastroenteritis and leukopenia in dogs worldwide. They are three subtypes of CPV-2 including CPV-2a, CPV-2b, and CPV-2c. The distribution status of CPV-2 subtypes has been shown differences in many countries.

AIMS

The aim of the present study was detection and phylogenetic analysis of different subtypes of CPV-2 circulating in two provinces of Iran, Tehran and Alborz.

METHODS

CPV-2 was detected using 555 primer pairs in collected samples. Phylogenetic analysis of CPV-2 subtypes was done using sequencing of the partial length of VP2 gene.

RESULTS

Twenty-eight CPV-2 were detected using 555 primer pair. The sequences of isolates were deposited in the GenBank database. Phylogenetic analysis revealed that all CPV-2c subtype isolates had very high sequence identity to China and Zambia that form a distinct cluster.

CONCLUSION

In conclusion, this study revealed the emergence of all CPV-2 variants in dogs in Iran. Thus, the continual monitoring of CPV-2 in domestic dogs should be further conducted on a large scale to determine the predominant variants and their distributions in the country and to follow the dynamics of CPV-2 in the Middle East region of Asia.

Genetic and Antigenic Evaluation of Foot-and-mouth Disease Virus Type A in the Endemic Area of Iran within 2014-2015

The foot-and-mouth disease virus (FMDV) with a wide variety of genomes and complicated biology is one of the infectious agents that put the lives of animals at risk. Therefore, to introduce suitable strains for vaccine production, it is essential to constantly evaluate genetic changes of circulating viruses in field. Within 2014-2015, a total of 126 clinical specimens consisting of epithelial tissue and vesicular fluid from tongue, dental pad, and hoofs suspected of FMD virus were submitted to the Reference Laboratory for FMD in Razi Vaccine and Serum Research Institute, and 86 of them were identified as FMD virus type A using sandwich Enzyme-Linked Immunosorbent Assay (ELISA). This virus was isolated from 42 samples from 16 provinces using cell culture. Firstly, the coding region that produces the main part of viral capsid was amplified by Polymerase chain reaction (PCR). This part of the genome by 800 bp length was related to the 1D gene that synthesizes the VP1 protein. The phylogenetic analysis of VP1 coding region determined two distinct genotypes with more than 15% nucleotide differences. The first cluster consisted of closely related viruses registered in the GeneBank of neighboring countries, including Afghanistan, Pakistan, and Turkey. All samples in Cluster1 were determined as relative viruses with genotype Iran-05. In-vitro serological examination indicated an antigenic relationship between Cluster 1 viruses and routine vaccine strain (A-IRN-2013). The second cluster with only two members was genetically far from earlier ones and could be considered a separate genotype. Furthermore, it was revealed that cluster 2 has not been previously reported in Iran. Genetic tracing indicated that these viruses might have been originated from circulating viruses from India. Antigenic evaluation exhibited that this group could not be cross-protected by the routine vaccinal strain (A-IRN-2013) used during the research period.

Nursing diagnosis identification by nurses in burn wards: A descriptive cross-sectional study

Aim

To identify and document patients' care needs, it is vital to provide quality care services. This study was aimed to describe care needs derived from records of patients with burn and to evaluate whether nurses employed the North American Nursing Diagnosis Association classification to formulate patients' care needs.

Design

A descriptive cross-sectional study.

Methods

In this study using the convenient sampling method, 430 nursing records reviewed in the burn wards. Data were collected using Gordon's checklist. The validity of the checklist assessed by content validity and the reliability of them calculated with inter-rater and internal consistency. Data analysed by SPSSv.24.

Results

The mean number of diagnoses per record was 1.94. The most frequent diagnosis was in the domain of Safety/Protection and the top two prevalent nursing diagnoses in Sina hospital were a risk for infection and risk for falls. From all of the detected diagnostic, about 83% were determinedly not related to one of 247 labels of the North American Nursing Diagnosis Association. Given that nurses provide nursing care as requested by physicians and patient care needs are not assessed and recorded by them, it can be concluded that there was no nursing thinking behind their nursing care.

Development of family-based follow-up care system for patients with burn in Iran: Participatory action research

Aim

After the discharge of patients with burns, quality of life, psychological and social adjustment, performance and their follow-up are ambiguous. Therefore, we decided to improve the status of family-based care programmes in patients with the burn.

Design

Participatory action research.

Methods

The participatory action research was conducted between the Faculty of Nursing, Sina Hospital's managers and multidisciplinary burn teams from 2017-2018. The procedure for data collection included focus group meetings with key informants, interviews, observation, and questionnaire. Qualitative data were analysed using the qualitative content analysis and qualitative data were analysed by SPSSv.24.

Results

The study, comprised of four phases, started in May 2017 and completed in 9 months. The results of quantitative showed that quality of life has a statistically significant difference before and after the action. The qualitative data resulted were grouped into 3 categories and 28 subcategories and were analysed in the SWOT Matrix. All the multidisciplinary burn teams together with the managers as a team working of the care providers and the academic researcher resulted in enablers the changes in providing health education and services as well as improving the quality of life of patients and their families.

Development of nursing care guideline for burned hands

Aim

To develop an evidence-based guideline to care for hand-burned patients.

Design

An integrative review.

Method

The search was conducted of EMBASE, PubMed, Web of Science, SCOPUS, Clinical Key, Iranmedex, Magiran, Scientific Information Database (SID), Cochran, CINAHL and Google Scholar databases from January 2000-August 2019. Following the formation of the research team, two researchers independently selected the eligible studies. The initial search resulted in 2,230 records; ultimately, 40 articles were identified to be the review after screening the records based on the study's inclusion and exclusion criteria. Quality of selected studies was evaluated with the MMAT method.

Results

Data syntheses of selected studies, coded by highlighting the relevant parts of the text, and assigning code words to these areas were done. Following this, a constant comparison was used to develop categories by combining codes. Finally, hand burns nursing care guideline was developed by categorizing descriptive themes in two main phases.

Conclusion

This review results have shown that evidence-based guidelines present high-quality recommendations for the healthcare team, which improves the quality of clinical care. Due to a lack of established guidelines in our context, it seems to be helpful to use evidence-based guidelines in managing burned hands.

The implementation of the nursing process in lower-income countries: An integrative review

Aims

This review study aimed to investigate the strategies for implementing the nursing process in the clinical practice and the assessment of the implementation rate of this process in clinical settings of lower-income countries.

Design

An integrative review.

Method

The search was conducted of EMBASE, MEDLINE, CINAHL, Scopus and ISI databases from 1975-July 2018. Following the formation of the research team, two researchers independently selected the eligible studies; finally, 39 articles were approved by the research team for this study.

Results

The researchers identified three themes: Effects of implementing the NP in clinical settings, Development and application of electronic software in the NP and Factors affecting the implementation of the NP. This review revealed that nurses and nursing managers in hospitals are interested in implementing the nursing process in the form of widely and continuously. But the necessary infrastructure, such as manpower, electronically or manually tools, has not yet been provided, and the implementation of the nursing process is done either imperfectly or not done.

Iranian nurses' knowledge, attitude and behaviour on skin care, prevention and management of pressure injury: A descriptive cross-sectional study

AIM

Pressure injuries as an indicator measuring the quality of nursing care and patient safety is a major health care problem worldwide. The aim of this study was to assess the knowledge, attitude and behaviour of nurses in preventing pressure injuries.

DESIGN

Descriptive cross-sectional study.

METHODS

This descriptive cross-sectional study enrolled 214 registered nurses in Iran. Patient satisfaction was assessed using pieker pressure ulcer knowledge test, attitude towards pressure ulcer tool and behaviour of pressure ulcer questionnaire. Data analysed by SPSSv.24 applying descriptive and inferential statistics.

RESULTS

The mean scores of knowledge, attitude and behaviour of nurses on the prevention of pressure injury were 27.24 (SD 5.23), 38.55 (SD 6.43) and 51.24 (SD 7.54), respectively. There was a correlation between knowledge, attitude and behaviour with the history of pressure injury training. Also, there was a significant relationship between knowledge with educational level and attitude with work experience. Knowledge, attitude and behaviour of nurses were in moderate level. Necessary measures to overcome problems such as the availability of pressure reducing equipments, motivating the nurses, eliminating the shortage of nurses and empowering nurses by holding practical workshops are important in providing patients safety.

Assessment of nurse-patient communication and patient satisfaction from nursing care

AIM

Professional communication between nurse and patient has a significant role in patient satisfaction with nursing care. The aim of this study was to assess nurse-patient communication and patient's satisfaction from nursing services in the burn wards of women and men.

DESIGN

Participants were all patients admitted to the Burn wards at the Sina Hospital of Tabriz between September-December 2018. Nurse-patient communication and patient's satisfaction were assessed using at the time of discharge. Data were analysed by SPSS applying descriptive and inferential statistics.

RESULTS

The results show that most patients were dissatisfied with nursing care. More than 80% did not know their nurse. There was a correlation between nurse-patient communication and patient satisfaction with nursing care and the sex variable was found to be significantly correlated with patients' satisfaction level. The weakness of nurses 'communication with patients was evident in our study and patients were dissatisfied from this kind of communication, and consequently, patients' satisfaction was reported very low. Improving the satisfaction of patients in the hospital should be the priorities of the hospital managers. Therefore, by educating staff, especially nurses, identifying motivating factors as well as identifying dissatisfaction factors, improved patient satisfaction.

MRS Shimming: An Important Point Which Should not be Ignored

BACKGROUND

Proton magnetic resonance spectroscopy (MRS) is a well-known device for analyzing the biological fluids metabolically. Obtaining accurate and reliable information via MRS needs a homogeneous magnetic field in order to provide well-defined peaks and uniform water suppression. There are lots of reasons which can disturb the magnetic field homogeneity which can be corrected by a process known as shimming. This study is intended to recall the importance of shimming and also the significant role of quality control (QC) in achieving an accurate quantification.

MATERIAL AND METHOD

An acrylic cylindrical quality control phantom was designed as an analog of brain MRS test phantoms in order to control the accuracy of the obtained signal of a 1.5 T Siemens MRI system which belonged to one of Shiraz hospitals. The signal of NAA, Cho, Cr, the combination of these metabolites and also the distilled water, which was used in this study, was evaluated using separate phantoms. A QC test was performed using Siemens QC phantom and a standard test phantom.

RESULTS

The spectrum of our home- made phantom had a significant difference with the expected spectrum. The results of checking the spectrum of metabolites separately also confirmed that there was a systemic problem that affects all the signals originated from all metabolites and even the pure distilled water. The MRS system could not pass QC tests, and peak broadening was common in all spectra. The complex spectrum of standard test phantom was not produced successfully by the MRS system.

DISCUSSION

By a simple check of the water peak characteristics, lots of information can be obtained, one of which is the status of shimming that has a considerable effect on the accuracy of the spectrum. Thus, performing an automatic or manual shimming is not a criterion of the spectrum accuracy, and performing a periodic quality control using a test phantom by a specialist is necessary.

CONCLUSION

Briefly, the quality control of MRS and all the other clinical device must be taken seriously. Sometimes QC can be the boundary of a right or a wrong decision for the patient.

Moral distress and burnout in Iranian nurses: The mediating effect of workplace bullying

BACKGROUND

Moral distress and workplace bullying are important issues in the nursing workplace that appear to affect nurse's burnout.

AIM

To investigate the relationship between moral distress and burnout in Iranian nurses, as mediated by their perceptions of workplace bullying.

ETHICAL CONSIDERATIONS

The research was approved by the committee of ethics in research of the Urmia University of Medical Sciences.

METHOD

This is a correlation study using a cross-sectional design with anonymous questionnaires as study instruments (i.e. Moral Distress Scale-Revised, Maslach Burnout Inventory and The Negative Acts Questionnaire-Revised). Data were collected from 278 nurses from five teaching hospitals in Urmia, the capital of Western Azerbaijan, northwest of Iran. Structural equation modeling and bootstrapping procedures were employed to recognize the mediating role of their perceptions of workplace bullying.

RESULTS

The mean score of moral distress, burnout, and the Negative Acts Questionnaire-Revised Scale among the participants were 91.02 ± 35.26, 79.9 ± 18.27, and 45.4 ± 15.39, respectively. The results confirmed our hypothesized model. All the latent variables of study were significantly correlated in the predicted directions. The moral distress and bullying were significant predictors of burnout. Perception of bullying partially mediated the relationship between moral distress and burnout. The mediating role of the bullying suggests that moral distress increases burnout, directly and indirectly.

CONCLUSION

Nursing administrators should be conscious of the role of moral distress and bullying in the nursing workplace in increasing burnout.

The Effect of Pre-Discharge Training on the Quality of Life of Burn Patients

Introduction: Many physical, psychological, social and economic complications have been reported after discharge, which have a negative impact on the quality of life of burn patients. The present research examines the effect of pre-discharge training program on the life quality of patients with burns.

Methods: This is a pre and post-experimental study with control group that was conducted in 2015 in teaching hospital Sina. The control group received the typical instructions upon being discharged from hospital while the experimental group received in-person training in the form of question-answer, pamphlets and a researcher-made instruction booklet. The patients’ life quality was evaluated when they were being discharged, a month and then three months after they were discharged.

Results: The result showed that the quality of life has a significant statistical difference across the three time points. And these differences are compared using Bonferroni’s adjustment multiple comparisons indicating that pre-discharge training affects the quality of life scores and this effect continues over time.

Conclusion: The results show that the pre-discharge training has significantly improved the life quality among the burns patients. The improvement of life quality is also correlated with the quantitative variable of total body surface area percent (TBSA %). Thus, planning and designing in-discharge training programs based on the existing context, combined with training packages focusing on the patients’ needs could be a very significant step in more successful implementation of the follow-up programs on the burn patients and improving their quality of life.

Lethal Area 50 in Patients with Burn Injuries in North West, Iran

Introduction: In view of their considerably high rates of mortality and morbidity, burns are still viewed as one of the most important health-threatening environmental hazards imposing a significant burden on the health care system in low and middle-income countries. This study seeks to determine the lethal area fifty percent (LA50) in all burn patients admitted over a period of five years and the factors influencing mortality in burn injuries. Methods: This study was a cross-sectional carried out from 2010 to 2014 in Sina Hospital of Tabriz, 1226 participant including 319 women, 346 men, 272 girls, and 289 boys were selected through stratified sampling. The demographic and clinical data of patients ( their age, gender, burn type, TBSA, the season and consequences of burning) were all extracted and then analyzed, using descriptive statistics (measures of central tendency and variability) and inferential statistics(chi-square and linear regression)at a significance level of 0.05. The LA50 was calculated through determining the relationship between the total body surface area and mortality rate (The extent of the body burns measured and recorded based on Lando Chart in hospitals). Results: The highest (47.6%) and the lowest (3.8%) rates of burns were observed among those aged below 16 and above 65, respectively. The majority of the participants were residents of cities (55.4%), married (34.6%), illiterate (56.6%), and housewives (14.8%). Most burns were caused by accidents (98.4%) at home (90.6%). Most patients had suffered first- and second-degree burns (68.4%), with no inhalation damages (99.5%). Hot liquids were the main culprit in most of the burns (58.7%) and the upper extremities were the most frequently affected areas (34.8%). There was .99 rise in mortality for every percent increase in TBSA, and there seemed to be a significant relationship between the age level and the eventual outcome- the higher the age, the more likely for the incident to end in death.LA50 was also determined 43.73 percent for five years. Finally, the study findings showed that female gender, TBSA and age are associated with death from burn. Conclusion: Given the high LA50 index at this center, it is of high priority in our country to enhance the public knowledge and the quality of the care provided for the burn patients. Patients at risk including women, children, elderly and extensive burns should be considered.

[Management of high thrombus burden in primary PCI]

A large thrombus burden is not uncommon in primary percutaneous coronary intervention, and is associated with more frequent complications. The role of intracoronary thrombolysis and glycoprotein IIb/IIIa inhibitors in the management of a large thrombus burden is discussed. The use of thromboaspiration must follow a particular logic and used with rigorous manipulations; the capacities of the protective filters are often exceeded. Stents dedicated to thrombus management can be used. Interest and limits of these stents are developed. Direct stenting should be encouraged, and delayed stenting probably considered for the most important thrombotic burden despite "negative" results in studies.
