RESUMO

The American Diabetes Association (ADA), European Association for the Study of Diabetes (EASD), Joint British Diabetes Societies for Inpatient Care (JBDS), American Association of Clinical Endocrinology (AACE) and Diabetes Technology Society (DTS) convened a panel of internists and diabetologists to update the ADA consensus statement on hyperglycaemic crises in adults with diabetes, published in 2001 and last updated in 2009. The objective of this consensus report is to provide up-to-date knowledge about the epidemiology, pathophysiology, clinical presentation, and recommendations for the diagnosis, treatment and prevention of diabetic ketoacidosis (DKA) and hyperglycaemic hyperosmolar state (HHS) in adults. A systematic examination of publications since 2009 informed new recommendations. The target audience is the full spectrum of diabetes healthcare professionals and individuals with diabetes.

RESUMO

A growing body of research is categorizing sex differences in both sickle cell anemia (SCA) and acute kidney injury (AKI); however, most of this work is being conducted in high-resource settings. Here, we evaluated risk factors and clinical parameters associated with AKI and AKI severity, stratified by sex, in a cohort of children hospitalized with SCA and vaso-occlusive pain crisis (VOC). The purpose of this study was to explore sex disparities in a high-risk, vulnerable population. This study was a secondary analysis of data collected from a cohort of Ugandan children between 2 and 18 yr of age prospectively enrolled. A total of 185 children were enrolled in the primary study; 41.6% were female and 58.4% were male, with a median age of 8.9 yr. Incident or worsening AKI (P = 0.026) occurred more frequently in female compared with male children, despite no differences in AKI on admission. Female children also had altered markers of renal function including higher creatinine levels at admission (P = 0.03), higher peak creatinine (P = 0.006), and higher urine neutrophil gelatinase-associated lipocalin (NGAL) at admission (P = 0.003) compared with male children. Female children had elevated total (P = 0.045) and conjugated bilirubin at admission (P = 0.02) compared with male children and higher rates of hematuria at admission (P = 0.004). Here, we report sex differences in AKI in children with SCA and VOC, including increased incidence and worsening of AKI in female pediatric patients, in association with an increase in biological indicators of poor renal function including creatinine, estimated glomerular filtration rate, and NGAL.NEW & NOTEWORTHY In this study, we report an increased risk of developing acute kidney injury (AKI) during hospitalization, worsening AKI, and death among females with sickle cell anemia (SCA) hospitalized with an acute pain crisis compared with males. The sex differences in AKI were not explained by socioeconomic differences, severity of pain, or disease severity among females compared with males. Together, these data suggest that female children with SCA may be at increased risk of AKI.

RESUMO

Crizanlizumab, a monoclonal antibody against P-selectin, has been shown to reduce vaso-occlusive crises (VOCs) compared to placebo in patients ≥ 16 years with sickle cell disease (SCD). However, there have been rare reports of patients experiencing severe pain and subsequent complications within 24 hours of crizanlizumab infusions. These events are defined as infusion-related reactions (IRRs). Informed by current literature and clinical experience, a group of content experts developed clinical guidelines for the management of IRRs in patients with SCD. We used the RAND/University of California, Los Angeles (UCLA) modified Delphi panel method, a valid, reproducible technique for achieving consensus. We present our recommendations for managing IRRs, which depend on patient characteristics including: prior history of IRRs to other monoclonal antibodies or medications, changes to crizanlizumab infusion rate and patient monitoring, pain severity relative to patient's typical SCD crises, and severe allergic symptoms. These recommendations outline how to evaluate and manage IRRs in patients receiving crizanlizumab. Future research should validate this guidance using clinical data and identify patients at risk for these IRRs.

RESUMO

Nitric oxide (NO), a vasodilator contributes to the vaso-occlusive crisis associated with the sickle cell disease (SCD). Vascular nitric oxide helps in vasodilation, controlled platelet aggregation, and preventing adhesion of sickled red blood cells to the endothelium. It decreases the expression of pro-inflammatory genes responsible for atherogenesis associated with SCD. Haemolysis and activated endothelium in SCD patients reduce the bioavailability of NO which promotes the severity of sickle cell disease mainly causes vaso-occlusive crises. Additionally, NO depletion can also contribute to the formation of thrombus, which can cause serious complications such as stroke, pulmonary embolism etc. Understanding the multifaceted role of NO provides valuable insights into its therapeutic potential for managing SCD and preventing associated complications. Various clinical trials and studies suggested the importance of artificially induced nitric oxide and its supplements in the reduction of severity. Further research on the mechanisms of NO depletion in SCD is needed to develop more effective treatment strategies and improve the management of this debilitating disease.

RESUMO

OBJECTIVE: To delineate the natural history of splenic complications other than loss of splenic function in children with sickle cell disease (SCD), we performed a retrospective chart review of patients with SCD treated at the Texas Children's Hospital. METHODS: We determined the dates of diagnoses of splenic complications, the number of acute splenic sequestration crises (ASSC), and hydroxyurea treatment in pediatric patients with SCD. We also examined the association of hydroxyurea therapy with the onset and severity of ASSC. RESULTS: The cumulative prevalence of splenic complications was 24.7% for splenomegaly, 24.2% for ASSC, 9.6% for hypersplenism, and 5.6% for splenectomy. The cumulative prevalence of splenic complications was highest in patients with hemoglobin Sß0 (69.2%), intermediate in hemoglobin SS (33.3%), low in hemoglobin SC (9.0%), and non-existent in hemoglobin Sß+. The overall event rate of ASSC was 8.3 per 100 patient-years. The event-rate was 28.4 for hemoglobin Sß0, 10.9 for hemoglobin SS, and 3.5 for hemoglobin SC. Patients with hemoglobin SS and hemoglobin Sß0 on hydroxyurea therapy had a significantly higher occurrence of ASSC than those who were not, with event rates of 14.2 and 3.1, respectively. The event rate was also higher for children who started hydroxyurea before age 2 years than for those who started after this age (19.8 and 9.2, respectively). CONCLUSIONS: The prevalence and severity of splenic problems vary widely between different sickle cell genotypes, with hemoglobin Sß0 having the most severe complications. Hydroxyurea therapy is associated with increased incidence of ASSC, particularly when initiated before 2 years of age.

RESUMO

Disaster plant pathology addresses how natural and human-driven disasters impact plant diseases and the requirements for smart management solutions. Local to global drivers of plant disease change in response to disasters, often creating environments more conducive to plant disease. Most disasters have indirect effects on plant health through factors such as disrupted supply chains and damaged infrastructure. There is also the potential for direct effects from disasters, such as pathogen or vector dispersal due to floods, hurricanes, and human migration driven by war. Pulse stressors such as hurricanes and war require rapid responses, whereas press stressors such as climate change leave more time for management adaptation but may ultimately cause broader challenges. Smart solutions for the effects of disasters can be deployed through digital agriculture and decision support systems supporting disaster preparedness and optimized humanitarian aid across scales. Here, we use the disaster plant pathology framework to synthesize the effects of disasters in plant pathology and outline solutions to maintain food security and plant health in catastrophic scenarios. We recommend actions for improving food security before and following disasters, including (i) strengthening regional and global cooperation, (ii) capacity building for rapid implementation of new technologies, (iii) effective clean seed systems that can act quickly to replace seed lost in disasters, (iv) resilient biosecurity infrastructure and risk assessment ready for rapid implementation, and (v) decision support systems that can adapt rapidly to unexpected scenarios.

RESUMO

BACKGROUND: Given the protective effect of nurturing caregivers and families for child and adolescent mental health, there is a need to review and synthesize research evidence regarding the effectiveness of parenting and family interventions in low and middle-income countries, including humanitarian settings. To advance practice, further understanding of the active ingredients of such interventions and implementation factors that lead to effectiveness are essential. METHOD: This systematic review, an update from a previous review, included studies on any parenting or family intervention for children and adolescents aged 0-24, living in a low- or middle-income country, that quantitatively measured child or adolescent mental health outcomes. We searched Global Health, PubMed, PsychINFO, PILOTS and the Cochrane Library databases on the 9th July 2020, and updated on the 12th August 2022. Risk of bias was assessed using an adapted version of the NIH Quality Assessment Tool. We extracted data on: effectiveness outcomes, practice elements included in effective interventions, and implementation challenges and successes. MAIN FINDINGS: We found a total of 80 studies (n = 18,193 participants) representing 64 different family or parenting interventions, 43 of which had evidence of effect for a child or adolescent mental health outcome. Only 3 studies found no effect on child, adolescent or caregiver outcomes. The most common practice elements delivered in effective interventions included caregiver psychoeducation, communication skills, and differential reinforcement. Key implementation strategies and lessons learned included non-specialist delivery, the engagement of fathers, and integrated or multi-sector care to holistically address family needs. PRELIMINARY CONCLUSIONS: Despite a high level of heterogeneity, preliminary findings from the review are promising and support the use of parenting and family interventions to address the wider social ecology of children in low resource and humanitarian contexts. There are remaining gaps in understanding mechanisms of change and the empirical testing of different implementation models. Our findings have implications for better informing task sharing from specialist to non-specialist delivery, and from individual-focused to wider systemic interventions.

RESUMO

BACKGROUND: Being exposed to crises during pregnancy can affect maternal health through stress exposure, which can in return impact neonatal health. We investigated temporal trends in neonatal outcomes in Switzerland between 2007 and 2022 and their variations depending on exposure to the economic crisis of 2008, the flu pandemic of 2009, heatwaves (2015 and 2018) and the COVID-19 pandemic. METHODS: Using individual cross-sectional data encompassing all births occurring in Switzerland at the monthly level (2007-2022), we analysed changes in birth weight and in the rates of preterm birth (PTB) and stillbirth through time with generalized additive models. We assessed whether the intensity or length of crisis exposure was associated with variations in these outcomes. Furthermore, we explored effects of exposure depending on trimesters of pregnancy. RESULTS: Over 1.2 million singleton births were included in our analyses. While birth weight and the rate of stillbirth have remained stable since 2007, the rate of PTB has declined by one percentage point. Exposure to the crises led to different results, but effect sizes were overall small. Exposure to COVID-19, irrespective of the pregnancy trimester, was associated with a higher birth weight (+12 grams [95% confidence interval (CI) 5.5 to 17.9 grams]). Being exposed to COVID-19 during the last trimester was associated with an increased risk of stillbirth (odds ratio 1.24 [95%CI 1.02 to 1.50]). Exposure to the 2008 economic crisis during pregnancy was not associated with any changes in neonatal health outcomes, while heatwave effect was difficult to interpret. CONCLUSION: Overall, maternal and neonatal health demonstrated resilience to the economic crisis and to the COVID-19 pandemic in a high-income country like Switzerland. However, the effect of exposure to the COVID-19 pandemic is dual, and the negative impact of maternal infection on pregnancy is well-documented. Stress exposure and economic constraint may also have had adverse effects among the most vulnerable subgroups of Switzerland. To investigate better the impact of heatwave exposure on neonatal health, weekly or daily-level data is needed, instead of monthly-level data.

RESUMO

BACKGROUND: Nicardipine is commonly used in the management of hypertensive crises, except those involving cardiac contractility defects despite its ability to reduce afterload and pulmonary congestion. Consequently, there is limited literature evaluating nicardipine's role for this indication. The purpose of this study was to evaluate the efficacy and safety of nicardipine in adults with reduced ejection fractions presenting with acute heart failure with hypertension (AHF-H). METHODS: This was a retrospective study conducted at an academic Level 1 trauma center with an annual Emergency Department (ED) volume surpassing 100,000. The purpose of this study was to determine the efficacy and safety of nicardipine in adults with reduced ejection fractions presenting to the ED with AHF-H. Efficacy was determined by achievement of the physician prescribed blood pressure target range. The primary safety endpoints included the number of individuals who experienced bradycardia (< 60 beats per minute, bpm) or hypotension (systolic blood pressure, SBP, < 90 mmHg) while receiving nicardipine and for up to 15 min after its discontinuation. Patients were included if they were ≥ 18 years of age, received a continuous intravenous nicardipine infusion within six hours of presenting to the ED, and had an ejection fraction ≤ 40% per an echocardiogram obtained within three months of the study visit. Pregnant and incarcerated patients were excluded. RESULTS: Of the 500 patient charts reviewed, 38 met inclusion criteria. The median (interquartile, IQR) ejection fraction and brain natriuretic peptide (BNP) were 35% (25-40) and 731 pg/nL (418-3277), respectively. The median baseline heart rate and SBP were 90 bpm and 193 mmHg, respectively. The median physician specified SBP goal was 160 mmHg and all patients met this endpoint in a median time of 18 min. One (2.6%) patient in the total population developed both hypotension and bradycardia. This patient had an ejection fraction of 20%, was intubated, and received nicardipine in addition to esmolol for an aortic dissection without experiencing an adverse event until 30 min after dexmedetomidine was initiated. CONCLUSION: In this non-interventional study evaluating the use of nicardipine in patients with reduced ejection fractions presenting to the ED with AHF-H, nicardipine was found to be safe and effective. To our knowledge this is the largest study to date evaluating nicardipine in this patient population and positively contributes to the existing literature.

RESUMO

BACKGROUND: Many work-related stresses are experienced by oncologists. Ukraine is currently undergoing numerous crises, including the SARS-CoV-2 pandemic and military conflicts, which represent stressful situations. The aim of this study was to explore the personal resources that Ukrainian oncologists use to cope with work demands in a situation featuring manifold crises. This study identified the ways in which people deal with stressful situations and the roles that they play in shaping the challenging situations that they encounter (work-related behavior) as well as how they cope with stress (stress management). METHODS: Forty oncologists (18 men and 22 women) working in a clinic in Kharkiv (Ukraine) with an average age of 46.3 ± 13.37 years (ranging from 26 to 74 years) participated in this study. The occupational psychological survey consisted of the Work-Related Behavior and Experience Patterns (German: Arbeitsbezogenes Verhaltens- und Erlebensmuster, AVEM) questionnaire, which was developed by Schaarschmidt and Fischer, and the Differential Stress Inventory (DSI), which was developed by Léfevre and Kubinger. RESULTS: 65% of oncologists exhibited AVEM risk pattern A or B. No gender differences were observed with regard to the distribution of AVEM patterns. Women obtained significantly higher scores than did men on only one dimension: experience of social support (4.86 vs. 3.44; p = 0.045). When the DSI categories were differentiated by gender, no significant differences were observed. Spearman's correlation analysis revealed a medium-sized correlation between perfection striving and palliative coping (ρ = 0.404). CONCLUSIONS: Few gender-based differences in work-related behaviors, experiences, and stress management strategies are evident among oncologists. AVEM risk patterns are more prevalent among Ukrainian oncologists than among comparable occupational groups, and interventions in the context of health management are recommended.

RESUMO

BACKGROUND: Frail people receiving home care services face an increased risk of developing crisis, which can result in adverse events, coercive measures, and acute institutionalisation. The prevalence of frailty is expected to increase due to the ageing population in most countries. However, our knowledge of the process leading to crises among frail community-dwelling patients remains limited. The aim of our study was to explore how users of home care services and their next of kin experienced crises and how these crises were approached by home care services. METHODS: A qualitative explorative design with 21 interviews was conducted. We explored crises within the last year that had led to an acute institutionalisation (hospital or nursing home) or to an unstable situation with high risk of institutionalisation. Systematic text condensation (STC) was used to analyse the data. RESULTS: Our findings are summarised into one overarching theme; an organisation working mainly reactively instead of proactively, which is supported by four subthemes: (1) insufficient communication-a determinant of crises, (2) the lack of a holistic approach, (3) a sense of being a burden, and (4) the complexity of crises. The reactive approach is demonstrated in the participant's experience of insufficient communication and the lack of a holistic approach from the service, but also in the user's sense of being a burden, which seems to be reinforced by the experienced busyness from the staff in the home care services. This reactive approach to crises seems to have contributed to difficulties in detecting the various stressors involved in the complex process leading to crisis. CONCLUSIONS: Our findings suggest that home care services tend to be characterised by a reactive approach to rising instability and the development of crises for users. This can be interpreted as an emergent property of the organisation and the adaptation towards exceeding demands due to insufficient capacity in health care services. We recommend the use of multicomponent care programmes comprising interdisciplinary case conferences in home care services to implement a cultural change that can shift the service from a reactive, fragmented, and task-oriented approach to a more proactive approach.

RESUMO

INTRODUCTION: Pulmonary hypertension in children is associated with high rates of adverse events under anesthesia. In children who have failed medical therapy, a posttricuspid shunt such as a Potts shunt can offload the right ventricle and possibly delay or replace the need for lung transplantation. Intraoperative management of this procedure, during which an anastomosis between the pulmonary artery and the descending aorta is created, is complex and requires a deep understanding of the pathophysiology of acute and chronic right ventricular failure. This retrospective case review describes the intraoperative management of children undergoing surgical creation of a Potts shunt at a single center. METHODS: A retrospective case review of all patients under the age of 18 who underwent Potts shunt between April 2013 and June 2022. Medical records were examined, and clinical data of demographics, intraoperative vital signs, anesthetic management, and postoperative outcomes were extracted. RESULTS: Twenty-nine children with medically refractory pulmonary hypertension underwent surgical Potts shunts with a median age of 12 years (range 4 months to 17.4 years). Nineteen Potts shunts (65%) were placed via thoracotomy and 10 (35%) were placed via median sternotomy with use of cardiopulmonary bypass. Ketamine was the most frequently utilized induction agent (17 out of 29, 59%), and the majority of patients were initiated on vasopressin prior to intubation (20 out of 29, 69%). Additional inotropic support with epinephrine (45%), milrinone (28%), norepinephrine (17%), and dobutamine (14%) was used prior to shunt placement. Following opening of the Potts shunt, hemodynamic support was continued with vasopressin (66%), epinephrine (62%), milrinone (59%), dobutamine (14%), and norepinephrine (10%). Major intraoperative complications included severe hypoxemia (21 out of 29, 72%) and hypotension requiring boluses of epinephrine (10 out of 29, 34.5%) but no patient suffered intraoperative cardiac arrest. There were four in-hospital mortalities. DISCUSSION: A Potts shunt offers another palliative option for children with medically refractory pulmonary hypertension. General anesthesia in these children carries high risk for pulmonary hypertensive crises. Anesthesiologists must understand underlying physiological mechanisms responsble for acute hemodynaic decompensation during acute pulmonary hypertneisve crises. Severe physiological perturbations imposed by thoracic surgery and use of cardiopulmonay bypass can be mitigated by aggresive heodynamic support of ventricle function and maintainence of systemic vascular resistance. Early use of vasopressin, before or immidiately after anesthesia induction, in combination with other inotropes is a useful agent during the perioperative care of thes. Early use of vasopressin during anesthesia induction, and aggressive inotropic support of right ventricular function can help mitigate effects of induction and intubation, single-lung ventilation, and cardiopulmonary bypass. CONCLUSIONS: Our single center expereince shows that the Potts shunt surgery, despite high short-term mortaility, may offer another option for palliation in children with medically refractory pulmonary hypertension.

RESUMO

Major financial legislation is invariably enacted in the wake of a financial crisis. However, legislating following a crisis is hazardous because information is scarce regarding causes of the crisis, let alone what would be an appropriate response. Compounding the lack of information, crisis-driven legislation is sticky, but financial markets are dynamically innovative, which can undermine the efficacy of regulation. As a result, it is foreseeable that such legislation will contain at least some provisions that are inapt or inadequate or, more often, have consequences that are not well understood or even knowable. This article advocates the use of sunsetting as a mechanism for mitigating the potentially adverse consequences of crisis-driven financial legislation. With sunsetting, after a fixed time span, legislation and its implementing regulation must be reenacted to remain in force. This approach has parallels in evolutionary biology, in which a central issue is the ability to adapt to changing environments. Sunsetting does not mean simply discarding (or reenacting) existing regulations, but revisiting them and improving them, much as mutation and recombination do in the evolutionary process.

RESUMO

Globally, human-caused environmental impacts, such as habitat loss, have seriously impacted raptor species, with some 50% of species having decreasing populations. We analyzed global patterns of distribution of all 557 raptor species, focusing on richness, endemism, geographic range, conservation status, and population trends. Highest species diversity, endemism, species at risk, or restricted species were concentrated in different regions. Patterns of species distribution greatly differed between nocturnal and diurnal species. To test the efficiency of the global protected areas in conserving raptors, we simulated and compared global reserve systems created with strategies aiming at: 1) constraining the existing system into the final solution; and 2) minimizing the socioeconomic cost of reserve selection. We analyzed three targets of species distribution to be protected (10, 20, 30%). The first strategy was more efficient in meeting targets and less efficient in cost and compactness of reserves. Focusing on actions in the existing protected areas is fundamental to consolidate conservation, and politically and economically more viable than creating new reserves. However, creating new reserves is essential to protect more populations throughout the species' geographic range. Our findings provide a fundamental understanding of reserves to maintain raptor diversity and reduce the global population and species extinction crisis.

RESUMO

'Forgotten crises' constitute a permanent background to any present and future global humanitarian and development efforts. They represent a significant impediment to promoting lasting peace given concurrent catastrophes exacerbated by climate change. Yet, they are routinely neglected and remain unresolved. Building on critical and feminist approaches, this paper theorises them as forgotten sites of local knowledge production. It asks: what is local knowledge of and from forgotten crises? How can it be recovered and resignified, and what lessons can such knowledge provide at the global level? Drawing on examples from the intersections of conflict, disasters, and pandemics in the Philippines, the paper makes a case for valuing local knowledge arising from forgotten crises because of its potential contribution to adapting global humanitarian and development systems to address crises on multiple fronts. Such epistemic margins are generative of vantage points that can present a fuller account of how different crises interact and how best to respond to them.

RESUMO

Little evidence exists on the design and implementation of anticipatory action (AA) in complex crises. This article examines a 2022 United Nations 'early action' pilot in South Sudan in advance of extreme flooding. As a case study of efforts to act in a complex crisis, it contributes to learning on assisting conflict-affected and displaced populations in advance of extreme weather events. The research points towards the possibility and value of implementing forecast-informed early action in complex contexts with limited forecast skills and multiple hazards when trigger-based AA is not possible. It also argues for the need to link AA implemented in complex crises to development and peacebuilding actors and processes. More broadly, examining the perceptions and processes of AA in the form of early action, rather than a formal AA framework, is highly relevant for the AA community as attention is increasingly placed on providing AA in countries affected by fragility and conflict.

RESUMO

How do protracted crises shape indigenous food systems, and what are their ramifications for food and nutritional security? Building on decolonial and interdisciplinary research approaches, this paper assesses the consequences of militarised violence for Kashmir's food system. We document the impact of settler-colonialism and conflict-induced agrarian changes on delocalisation of diets. The protracted nature of the crises has two key implications for changes in dietary patterns. First, land control over common land dispossesses the local population and hinders food production. Second, disenfranchisement from (agricultural) land has led to increased reliance on markets that are flooded by imported foods as local production declines. The paper argues that the state plays an important role in food system changes by destroying local patterns of food production and consumption. Slow violence and agrarian de-development serve as tools to de-develop the local food system. Indigenous food cultures form part of everyday resistance and resilience that are operationalised as mitigation and adaptation strategies to address food insecurity.

RESUMO

This paper investigates the biological, socio-economic, and institutional factors shaping the individual risk of death during a major pre-industrial epidemic. We use a micro-demographic database for an Italian city (Carmagnola) during the 1630 plague to explore in detail the survival dynamics of the population admitted to the isolation hospital (lazzaretto). We develop a theoretical model of admissions to the lazzaretto, for better interpretation of the observational data. We explore how age and sex shaped the individual risk of death, and we provide a one-of-a-kind study of the impact of socio-economic status. We report an inversion of the normal mortality gradient by status for those interned at the lazzaretto. The rich enjoyed a greater ability to make decisions about their hospitalization, but this backfired. Instead, the poor sent to the lazzaretto faced a relatively low risk of death because they enjoyed better conditions than they would have experienced outside the hospital.

RESUMO

Intensive home treatment (IHT) has shown to be a feasible alternative to hospitalization for the management of acute psychiatric episodes, but there are no real-world studies assessing if patients with a first IHT use it again for the management of their recurrences. The objectives of this retrospective cohort study were to map the use ofacute treatment resources after the implementation of IHT in our territory through the establishment of trajectories of management, and to disentangle if there are profiles of patients who fit better each trajectory. We included the first 1000 episodes admitted to IHT, of which we selected those that corresponded to the first IHT of a patient (index admission). Trajectories after the index admission were: (T-A) absence of use of acute resources, (T-B) only IHT, and (T-C) at least one hospitalization. Follow-up ranged from 6 months to 6 years. We calculated the frequency of each trajectory and performed univariate analyses searching for associations between trajectory and clinical factors. Among those patients with psychiatric history (N = 659), 66.2% followedT-A, 11.2% T-B, and 22.6% T-C. The probability of following T-C was higher for patients with a psychotic disorder (pBonf = 0.018) and with previous hospitalizations (pBonf < 0.0001). Among those patients without psychiatric history (N = 168), 82.7% followed T-A, 6.6% T-B, and 10.7% T-C. The probability of following T-B was higher for those with a higher severity at the index admission (pBonf = 0.028). This study shows that some -or even all- recurrences of some subjects were successfully managed with IHT, providing real-world evidence for its use in acute psychiatric conditions.

RESUMO

Agricultural production in vertical farms (VF) will play a prominent role in preventing environmental crises, its good governance and maintaining food security for everyone in the world. The ecological footprint in Guilan province significantly exceeds its biological capacity, indicating considerable pressure on its natural resources and ecosystems. This problem, which is mostly due to the use of traditional production methods in the agricultural sector, requires a change in lifestyle and production methods. The purpose of the current research is the feasibility of VF in Guilan province with the help of the Strengths, Weaknesses, Opportunities, and Threats (SWOT) model and Quantitative Strategic Planning Matrix (QSPM). After identifying internal factors (strengths and weaknesses) and external factors (opportunities and threats) affecting production in VF, the necessary strategies were determined and then prioritized using the QSPM matrix. Necessary information through written scientific sources and survey studies based on key questions between two groups of professors of geography and rural planning, water resources engineering, soil, architecture and experts from the plant production department and the head of the environment department, Jihad Agricultural Organization of Guilan province and the organization Food hygiene was achieved. The statistical population participating in the survey was 30 people. The results of the research showed that 7 strategies were formulated based on strengths, weaknesses, opportunities, and threats and were prioritized based on the importance of four strategies in the QSPM table. The first priority for ensuring food security in Guilan province is to focus on increasing agricultural productivity per unit area. This strategy is crucial considering the challenges of low ownership and limited land availability in the region. Thus, enhancing productivity per unit area should be given utmost priority to meet the food demands of the population. The appropriate strategy for VF production in Guilan province is a competitive-aggressive strategy and being in this position requires attracting the necessary funds. This study fills research gaps by providing a comprehensive assessment of the feasibility of vertical farming in Guilan province. The emphasis on methodology, strategic planning, and addressing food security and environmental challenges contributes to the existing body of knowledge. By highlighting the transferability and adaptability of the research findings, other researchers can utilize the methods and adapt the strategies to their own regions, promoting further research and advancement in the field of sustainable agriculture.
