RESUMEN

BACKGROUND: Childhood obesity has tripled, reaching critical levels of malnutrition. This factor is directly associated with a poorer health-related quality of life of the child and adolescent population. This article presents the study protocol of the project "Strong schoolchildren with a healthy lifestyle" (EF-Salud), which seeks to analyze the effects of a multicomponent program based on muscle strength exercises, sleep nutritional recommendations, and the use of screens in Chilean educational centers with extremely cold weather. METHODS: The study protocol of a randomized controlled trial with a pre- and post-test conducted according to the CONSORT statement is reported. The total sample (n = 144) will be schoolchildren from six different school years, four of which will perform an intervention and two control. Intervention group 1 (from two different school years) will receive a muscular strength exercise program in the classroom once a day from Monday to Friday for six months and nutritional, sleep, and use of screens recommendations once a week. Intervention group 2 (from two different school years) will receive a program of nutritional, sleep, and use of screens recommendations once per week for six months. The control group (from two different school years) will carry out their usual school day in relation to physical education classes. Before and after the intervention, the investigators will evaluate the cardiovascular risk, physical condition, and lifestyle related to sleep and use of screens. EXPECTED RESULTS: The schoolchildren in intervention group 1 will obtain significant results in increased strength, decreased cardiovascular risk, improved sleep habits, and fewer hours of screen use compared to the other two groups.

RESUMEN

Naturally fluctuating temperatures provide a constant environmental stress that requires adaptation. Some fungal pathogens respond to heat stress by producing new morphotypes that maximize their overall fitness. The fungal wheat pathogen Zymoseptoria tritici responds to heat stress by switching from its yeast-like blastospore form to hyphae or chlamydospores. The regulatory mechanisms underlying this switch are unknown. Here, we demonstrate that a differential heat stress response is ubiquitous in Z. tritici populations around the world. We used QTL mapping to identify a single locus associated with the temperature-dependent morphogenesis and we found two genes, the transcription factor ZtMsr1 and the protein phosphatase ZtYvh1, regulating this mechanism. We find that ZtMsr1 regulates repression of hyphal growth and induces chlamydospore formation whereas ZtYvh1 is required for hyphal growth. We next showed that chlamydospore formation is a response to the intracellular osmotic stress generated by the heat stress. This intracellular stress stimulates the cell wall integrity (CWI) and high-osmolarity glycerol (HOG) MAPK pathways resulting in hyphal growth. If cell wall integrity is compromised, however, ZtMsr1 represses the hyphal development program and may induce the chlamydospore-inducing genes as a stress-response survival strategy. Taken together, these results suggest a novel mechanism through which morphological transitions are orchestrated in Z. tritici - a mechanism that may also be present in other pleomorphic fungi.

RESUMEN

OBJECTIVE: To examine the effects of the COVID-19 pandemic among Latino communities, with an emphasis on understanding barriers and facilitators to vaccine intention prior to the development of the vaccine. METHODS: Qualitative data were collected between April and June 2020 from 3 focus groups with Latino adults (n = 21) and interviews with administrators of community-based organizations serving Latino communities (n = 12) in urban (Los Angeles) and rural (Fresno) California, supplemented by Community Advisory Board input in May 2021to elucidate the findings. Data were analyzed with deductive content analysis. RESULTS: We have identified four main themes that are barriers to vaccinating against COVID-19: 1) concerns about accessing appropriate healthcare services, 2) financial issues and 3) immigration matters, as well as 4) misinformation. CONCLUSIONS: Findings illustrate the pervasive role of addressable social determinants of health in the intention of rural and urban Latino communities in being vaccinated, which is a pressing public health issue. Policy implications: Findings provide evidence for a systemic shift to prioritize equitable access to COVID-19 vaccines to Latino communities.

RESUMEN

Obesity is a worry because it is associated with a greater burden of disease, and it has been shown to be related to the health habits and physical condition of children and adolescents. OBJECTIVE: To associate physical fitness, screen time, and sleep habits with the different categories of obesity in schoolchildren from the extreme south of Chile. METHODS: 583 schoolchildren were included in this cross-sectional analysis. The screen time and sleep habits were measured with the Sleep Self-Report questionnaire, while the physical fitness was assessed with the Alpha Fitness test battery. The Body Mass Index/age (BMI/age) and the Waist-to-Height ratio (WtHr) were used to define adiposity using the following categories: healthy weight/low-risk waist-to-height ratio (H/LR), healthy weight/high-risk waist-to-height ratio (H/HR), overweight/low-risk waist to height ratio (O/LR), and overweight/high-risk waist to height ratio (O/HR). RESULTS: A considerable number of schoolchildren (23.2%) presented sleep problems, while the mean screen time was 9.3 (95% CI: 8.4; 10.1) hours/day. Schoolchildren classified as H/HR showed better physical fitness than the O/HR group but worse physical fitness than the H/LR group. CONCLUSIONS: Significant differences were evidenced in the physical fitness between the adiposity categories, which could open future lines of research concerning the characterization of the healthy weight-obese adiposity categories in children.

RESUMEN

Introduction: Despite evidence that Hispanic/Latino populations are 1.5 times more likely than non-Latino Whites to develop Alzheimer's disease and related dementias (ADRD), Latinos are underrepresented in clinical trials testing treatments for ADRD. Data are needed on facilitators of ADRD clinical trial participation in Latinos. We leveraged in-depth qualitative methods to elucidate barriers and facilitators to participating in ADRD clinical trials in a large and diverse sample of Latinos; and to provide timely and actionable strategies to accelerate representation of Latinos in clinical trials on ADRD. Methods: Data were collected in California between January 2019 and June 2020 from 25 focus groups (FGs): eight with Latino adults ages 18 to 49 (n = 54), nine with Latino adults ages 50+ (n = 75), and eight with caregivers of Latino older adults with ADRD (n = 52). Twelve community-based organization administrators were also interviewed. Transcripts of FGs and interviews were entered into Atlas.ti software. Three independent team members analyzed the transcripts with inductive/deductive qualitative content analysis. We triangulated data from stakeholder groups across sites, we used collaborative coding, and used the Consolidated Criteria for Reporting Qualitative Research. Results: An overarching theme was a tension between wanting to learn more about ADRD and to participate in ADRD research but having limited awareness and opportunity. Five themes were identified: (1) remaining in limbo, (2) wanting information about ADRD, (3) wanting information on research about ADRD, (4) clearing researchers through trusted local organizations, and (5) practicing altruism through engagement in research opportunities. Discussion: To increase representation of Latino communities in clinical trials on ADRD, bilingual information and education on ADRD and clinical trials needs to be better disseminated. Also, working with trusted local, regional, and national organizations can increase participation. Importantly, Latino participation can increase when research teams demonstrate altruistic actions and inform participants of public health reasons requiring their involvement. HIGHLIGHTS: Participation in clinical trials on Alzheimer's disease and related dementias (ADRD) is limited among Latinos/Hispanics.Knowing the high prevalence of ADRD in Latinos increases willingness to participate.Observing altruism from researchers increases willingness to participate.Invitations from multiple organizations increases willingness to participate.Researchers should include public health reasons requiring Latinos' involvement.

RESUMEN

Introduction: Nocturnal enuresis is a common problem affecting 20% of 5-year-old children; its prevalence decreases with age. Nocturnal bedwetting in children younger than 5 is generally accepted by parents and society, but the expectation of parents is that children will achieve a higher degree of responsibility and increased control with age. Some studies have identified maternal distress as a factor associated with childhood urinary incontinence; specifically, maternal stress, maternal depression, and maternal anxiety. The aim of this study was to compare the degree of anxiety (trait and state) among mothers of children with nocturnal enuresis and mothers of healthy children. Methods: This was a prospective, cross-sectional, comparative study including two groups: a control group of 25 mothers of healthy children from open population, and an enuresis group of 25 mothers of children with nocturnal enuresis of the pediatric urology clinic of a third-level Mexican Hospital. STAI-T and STAI-S tests were performed and assessed blindly. Quantitative variables were compared using the Mann−Whitney U test, and qualitative determinations using a chi-square test or Fischer's exact test. Results: The STAI-S and STAI-T tests results identified 14 (56%) mothers of enuretic children with moderate-to-severe trait anxiety versus 4 (16%) mothers from the control group and moderate-to-severe state anxiety in 23 (92%) of the mothers of enuretic children compared to 7 (28%) control-group mothers. The anxiety scores were significantly higher for the enuresis group for both tests: STAI-T: 53.00 ± 8.39 versus 41.52 ± 9.61 (p < 0.001) and STAI-S: 56.48 ± 6.83 versus 43.84 ± 10.57 (p < 0.001). Conclusion: Mothers of children with nocturnal enuresis present state anxiety ranging from moderate to severe. In clinical practice, our results indicate that the transitory emotion experienced by mothers of enuretic children cannot be neglected in an enuresis treatment program, state anxiety needs to be evaluated, and psychological interventions need to be implemented.

RESUMEN

OBJECTIVE: To analyze the perception of physical fitness, screen time, and self-reported sleep hygiene in children and adolescents (CA) from the extreme south of Chile and its associations with waist-to-height ratio (WtHr). MATERIAL AND METHODS: An observational cross-sectional study was conducted in a sample of 594 schoolchildren from 5th to 8th grade of primary education, belonging to municipal educational establishments in the Magallanes region, Chile. Cardiorespiratory fitness was assessed through the 20-m shuttle run test, muscle strength through handgrip and the standing broad jump test, physical fitness perception through the International Fitness Scale, and central obesity through the waist-to-height index. In addition, sleep hygiene and screen time were measured. RESULTS: More than 92% of CA spent more than two hours a day watching or using screens. In addition, CA with excess central adiposity had a lower perception of physical fitness, and lower muscle strength and cardiorespiratory fitness compared to CA with normal values of adiposity. CONCLUSIONS: CA of the present study spent a high number of hours watching or using screens and had poor sleep quality. In addition, excessive central adiposity was associated with lower physical fitness.

RESUMEN

Resumen Antecedentes La pandemia por COVID-19 ha impactado en la actividad física y salud psicológica de estudiantes universitarios. Objetivo Analizar el comportamiento de la actividad física durante la pandemia por COVID-19 y su asociación con el bienestar subjetivo y salud mental en estudiantes universitarios en Chile. Método Estudio transversal en una muestra de 469 estudiantes de diferentes universidades de Chile (67,4% mujeres, M= 21,7 DT= 2,45 años). Se midió el comportamiento de la actividad física, bienestar subjetivo y salud mental. Resultados Los estudiantes que mantuvieron un comportamiento físicamente activo antes y durante la pandemia presentaron mayor bienestar subjetivo (hombres: p = 0,020; y mujeres p <0,0001) que quienes se mantuvieron físicamente inactivos antes y durante la pandemia (mujeres M= 4,84, DE= 1,64; hombres M= 4,46, DT= 1,27). Las mujeres que se volvieron físicamente inactivas durante la pandemia tuvieron menos experiencias afectivas negativas que mujeres que eran inactivas antes de la pandemia ( F (3,293)=3,118; p =0,026). La sintomatología de salud mental se reportó con menor frecuencia en estudiantes físicamente activos que inactivos. Conclusión Estudiantes que se mantuvieron físicamente activos antes y durante la pandemia mostraron mejores indicadores de bienestar subjetivo y salud mental que quienes se mantuvieron físicamente inactivos o pasaron a ser físicamente inactivos durante la pandemia. La actividad física debe promoverse en la educación superior, debido a su potencial efecto protector en el manejo de consecuencias psicológicas durante una crisis pandémica.


Abstract Background The COVID-19 pandemic has impacted on the physical activity and psychological health of university students. Objective To analyze the physical activity during the COVID-19 pandemic and its association with subjective well-being and mental health in university students in Chile. Method Cross-sectional study in a sample of 469 students from different Chilean universities (67.4% women, M = 21.7 SD = 2.45 years). The physical activity, subjective well-being and mental health was measured. Results Students who maintained a physically active behavior before and during the pandemic presented higher subjective well-being (men: p = 0.020; and women p <0.0001) than those who were physically inactive before and during the pandemic (women M = 4 , 84, SD = 1.64; men M = 4.46, SD = 1.27). Women who became physically inactive during the pandemic had fewer negative affective experiences than women who were inactive before the pandemic (F (3,293) = 3.118, p = 0.026). Mental health symptoms were reported less frequently in physically active than inactive students. Conclusion Students who were physically active before and during the pandemic showed better indicators of subjective well-being and mental health than those who were physically inactive or became physically inactive during the pandemic. Physical activity should be promoted in higher education, due to its potential protective effect in managing psychological consequences during a pandemic crisis.

RESUMEN

BACKGROUND: Pediatric spinal anesthesia is an old technique whose use is not widespread, in spite of reducing the risk of cardiorespiratory events (hypoxemia, bradycardia, and hypotension) associated with general anesthesia, especially in neonates and infants. This retrospective cohort study aimed to assess the safety and effectiveness of the pediatric spinal anesthesia program at our tertiary care hospital over 11 years. METHODS: Two hundred children, between 8 days and 13 years of age, who underwent lower body surgery under spinal anesthesia from May 2010 to July 2021 were included. Demographic and procedural data were collected, and success, failure, and complication rates calculated. RESULTS: The success rate was 97.5% (n = 195). The incidence of complications was 2% (n = 4). They were 2 cases of intraoperative hypoxemia and 2 cases of postoperative postdural puncture headache , and they quickly resolved with no sequelae. CONCLUSION: Pediatric spinal anesthesia is a safe and effective technique with good acceptance among anesthesiologists. Thus, the implementation of a pediatric spinal anesthesia program at a tertiary care hospital is feasible and affordable.

RESUMEN

OBJECTIVE: To compare cardiovascular risk and cardiorespiratory capacity in schoolchildren from a region in the extreme south of Chile according to nutritional status and muscular strength. METHODS: An analytical cross-sectional study was performed on a sample of 594 schoolchildren from 5th to 8th grade in the extreme south of Chile. Based on body mass index and lower limb muscle strength, participants were divided into four groups: high strength-normal weight, high strength-overweight/obese, low strength-normal weight, and low strength-overweight/obese. Then, waist-to-height ratio and cardiorespiratory capacity, measured with the 20 m shuttle run test, were assessed to determine their cardiovascular risk, comparing the four groups. RESULTS: The overweight/obese group with high muscular strength presented better indicators in anthropometric variables (waist circumference and waist-to-height ratio) than their peers with low muscular strength. Additionally, the overweight/obese group with low muscular strength presented a lower cardiorespiratory capacity than their peers with high muscular strength. Both results were observed in boys and girls. CONCLUSION: The results of this study suggest that overweight/obese schoolchildren with high muscle strength present healthier anthropometric indicators and greater cardiorespiratory capacity than their peers with low muscle strength. These results confirm the relevance of measuring muscle strength in schoolchildren and its usefulness to assess functionality. These results encourage the scientific community to continue studying the role that muscle strength plays in modulating the effects of overweight and obesity on respiratory and cardiovascular conditions in childhood.

RESUMEN

AIM: To analyze the characteristics of multicomponent interventions to reduce childhood overweight and obesity in territories with an extremely cold climate. METHODS: A systematic review was conducted following the PRISMA statement. MEDLINE, PsycNet, SciELO, and grey literature databases were reviewed in the period between 2010 and 2020. RESULTS: 29 articles were included (n = 4434 participants; 9.3 years; 56% women) with an average adherence of 86%, 100% being the highest adherence, for the physical activity and nutrition interventions. The primary variables studied were BMI, BMI Z-score BMI-SDS and, additionally, the secondary variables studied were nutritional status and physical and mental health. In 72% of the interventions presented, positive effects were seen on the reduction of BMI, including in parents and their children. The interventions were carried out mainly by nutritionists in health centers. The duration of the 29 interventions was ≤6 months and ≥12 months, in 59% and 41% of the studies, respectively. 57% of the studies reported post-intervention results. 86% of the interventions included a physical activity component, 80% included a nutrition component, 66% included a behavioral therapy component and 55% included an education component. Concerning the effects of the intervention on the primary outcome, in interventions with a duration equal to or less than six months, the most effective interventions included recreational activities, education, and nutritional programs. In interventions lasting 12 months or more, the most effective interventions included physical activity recommendations, nutritional and physical exercise programs, and cooking classes. CONCLUSIONS: This systematic review analyzed the effectiveness of, and characterized, multicomponent interventions lasting for 6 and 12 months, aiming to treat childhood obesity in extremely cold climates. The most frequently used units of measurement were also analyzed and summarized. Evidence derived from RCT. These results can be useful for designing future interventions to treat childhood obesity in territories with an extremely cold climate.

RESUMEN

Take-all disease, caused by the fungal root pathogen Gaeumannomyces tritici, is considered to be the most important root disease of wheat worldwide. Here we review the advances in take-all research over the last 15 years, focusing on the identification of new sources of genetic resistance in wheat relatives and the role of the microbiome in disease development. We also highlight recent breakthroughs in the molecular interactions between G. tritici and wheat, including genome and transcriptome analyses. These new findings will aid the development of novel control strategies against take-all disease. In light of this growing understanding, the G. tritici-wheat interaction could provide a model study system for root-infecting fungal pathogens of cereals.

RESUMEN

Reactive oxygen species are toxic byproducts of aerobic respiration that are also important in mediating a diversity of cellular functions. Reactive oxygen species form an important component of plant defenses to inhibit microbial pathogens during pathogen-plant interactions. Tolerance to oxidative stress is likely to make a significant contribution to the viability and pathogenicity of plant pathogens, but the complex network of oxidative stress responses hinders identification of the genes contributing to this trait. Here, we employed a forward genetic approach to investigate the genetic architecture of oxidative stress tolerance in the fungal wheat pathogen Zymoseptoria tritici. We used quantitative trait locus (QTL) mapping of growth and melanization under axenic conditions in two cross-populations to identify genomic regions associated with tolerance to oxidative stress. We found that QTLs associated with growth under oxidative stress as well as inherent growth can affect oxidative stress tolerance, and we identified two uncharacterized genes in a major QTL associated with this trait. Our data suggest that melanization does not affect tolerance to oxidative stress, which differs from what was found for animal pathogens. This study provides a whole-genome perspective on the genetic basis of oxidative stress tolerance in a plant pathogen.

RESUMEN

OBJECTIVE: this study aimed to determine the epidemiological, technical and clinical data of transjugular intrahepatic portosystemic shunt (TIPS) performed by Interventional Radiology departments in Spain. Furthermore, the total number of TIPS carried out in Spain was determined and compared with other countries. MATERIAL AND METHODS: a retrospective study was performed with the approval of the Ethical Committee of the Spanish Society of Interventional Radiology (SERVEI). A survey was performed with 31 items (demographic, technical and clinical data) for data acquisition on the current status of TIPS in Spain. The survey was sent to the 49 hospitals that SERVEI included in a previous registry with data of TIPS performed in Spain in 2016. RESULTS: of the 49 centers surveyed, 33 (67.35 %) replied to the survey. These centers had completed 265 of the 415 TIPS that year in Spain. The most frequent indication was upper GI bleeding from gastroesophageal varices, which accounted for 144 (54.33 %); 62.26 % of the TIPS were performed urgently and 37.7 % on a scheduled basis. The technical success was 89.16 ± 20.9 %, with a rebleeding rate of 17.9 %. Sixty-nine patients (26.03 %) presented complications, 19.62 % of them minor and 6.41 % major. The 30-day mortality related to the disease was 14.33 %, while mortality at one year was 18.49 %. CONCLUSION: notably in our study, the complications of TIPS did not show a clear relationship with the number of procedures performed. With regard to other countries like the United States and France, the number of TIPS in Spain per million inhabitants is currently substantially lower. There were no significant changes compared to the number completed in 2013.

RESUMEN

Black/African American populations are underrepresented as participants in dementia research. A major barrier to participation of African American older adults in dementia research is a tendency to distrust research institutions owing to both historical and contemporary racism. Building on the Ford framework, the objective of our study was to examine factors that influence participation in dementia research among African American older adults and caregivers, with an emphasis on understanding factors related to trust. Data were collected during January 2019 and March 2020 from 10 focus groups with African American older adults (n=91), 5 focus groups with caregivers (n=44), and interviews with administrators of community-based organizations (n=11), and meetings with our Community Advisory Board. Inductive/deductive content analysis was used to identify themes. The results identified an overall tension between distrust of researchers and a compelling desire to engage in dementia research. This overarching theme was supported by six themes that provided insights about the multiple layers of distrust, as well as expectations about the appropriate conduct of researchers and academic institutions. Strong commitment to the community was identified as a priority. The findings suggest that a paradigm shift is needed to increase the representation of African Americans in dementia research. In this new paradigm, earning the trust of African American communities becomes a systemic endeavor, with academic, state, and national institutions deeply committed to earning the trust of African American communities and guiding researchers in this endeavor. The findings also generated actionable recommendations to help improve representation of African American older adults in dementia research.

RESUMEN

BACKGROUND: The ability of fungal cells to undergo cell-to-cell communication and anastomosis, the process of vegetative hyphal fusion, allows them to maximize their overall fitness. Previous studies in a number of fungal species have identified the requirement of several signaling pathways for anastomosis, including the so far best characterized soft (So) gene, and the MAPK pathway components MAK-1 and MAK-2 of Neurospora crassa. Despite the observations of hyphal fusions' involvement in pathogenicity and host adhesion, the connection between cell fusion and fungal lifestyles is still unclear. Here, we address the role of anastomosis in fungal development and asexual reproduction in Zymoseptoria tritici, the most important fungal pathogen of wheat in Europe. RESULTS: We show that Z. tritici undergoes self-fusion between distinct cellular structures, and its mechanism is dependent on the initial cell density. Contrary to other fungi, cell fusion in Z. tritici only resulted in cytoplasmic mixing but not in multinucleated cell formation. The deletion of the So orthologous ZtSof1 disrupted cell-to-cell communication affecting both hyphal and germling fusion. We show that Z. tritici mutants for MAPK-encoding ZtSlt2 (orthologous to MAK-1) and ZtFus3 (orthologous to MAK-2) genes also failed to undergo anastomosis, demonstrating the functional conservation of this signaling mechanism across species. Additionally, the ΔZtSof1 mutant was severely impaired in melanization, suggesting that the So gene function is related to melanization. Finally, we demonstrated that anastomosis is dispensable for pathogenicity, but essential for the pycnidium development, and its absence abolishes the asexual reproduction of Z. tritici. CONCLUSIONS: We demonstrate the role for ZtSof1, ZtSlt2, and ZtFus3 in cell fusions of Z. tritici. Cell fusions are essential for different aspects of the Z. tritici biology, and the ZtSof1 gene is a potential target to control septoria tritici blotch (STB) disease.

RESUMEN

BACKGROUND: The treatment of venous thromboembolic disease the treatment of choice is systemic anticoagulation. However, the interruption of the inferior vena cava with filters has been recommended when anticoagulation fails or there is a contraindication. Due to the rising inferior vena cava filter (IVCF) complications, physicians are encouraged to retrieve them when there is no longer recommended. In daily practice, it may be a difficult close follow-up of these patients. In this study, the primary objective was to evaluate the IVCF retrieval rate of all implanted filters in a Spanish registry. Secondary objectives were to analyze the causes of failed retrieval, procedure-related complications, and outcomes at a 12-month follow-up. RESULTS: Three hundred fifty-six vena cava filters were implanted in 355 patients. The types of filter were: Gunther Tulip (Cook Medical) 160 (44.9%), Optease (Cordis) 77 (21.6%), Celect (Cook Medical) 49 (13, 7%), Aegisy (Lifetech Scientific) 33 (9.2%), Option ELITE (Argon Medical devices) 16 (4.4%), Denali filter (BD Bard) 11 (3.08%), ALN filter (ALN) 10 (2.8%). Removal was achieved in 274/356 (76,9%). eighty-two (23,1%) IVCF were not retrieved due to the following: 41 (11,5%) patients required ongoing filtration, 24 IVCF (6,7%) patients died before retrieval, and 17 (4,7%) impossibility of retrieval because of a tilted and embedded filter apex. There were no major complications observed. CONCLUSIONS: The global retrieval rate of IVCF was achieved in 76.9%, and the adjusted retrieval rate was of 94.15% with no major complications. IVCF tilting was associated with failure of filter removal in less than 5% of cases. This study demonstrates that the retrieval procedure of IVCF is controlled by the clinician and not by the interventional radiologist.

RESUMEN

Risk management in healthcare institutions begins by first identifying the potential risks within a certain organization or specific area and then goes on to develop further strategies to reduce harm. The most common tool for this type of analysis is Strengths-Weaknesses-Opportunities-Threats (SWOT). METHODS: We conducted a SWOT analysis in our pediatric anesthesia program: key factors were identified in a matrix, prioritized in a score table, represented in a graph, and finally analyzed. RESULTS: Items obtained partial scores from 20 to 120. The item "lack of clinical protocols" was given greater weight (60) and received a lower value (1), resulting in the highest partial score (60) among the negative key factors and indicating a need for greater efforts to improve this specific aspect. CONCLUSION: The SWOT tool proved effective in identifying safety and quality key factors, and it provided information for initiating an improvement program.
