RESUMO
BACKGROUND: Cyberbullying perpetration and victimisation have been associated with psychological distress, including depression and suicidal ideation. Prior studies have shown that the 'Dark Triad' personality traits (narcissism, Machiavellianism, and psychopathy) are associated with greater likelihood of perpetration, yet there is a research gap regarding potential mediators of this relationship. AIMS: To test whether functional and dysfunctional impulsivity act as mediators between Dark Triad traits and cyberbullying perpetration. METHODS: A cross-sectional online study was conducted, in which a sample of 141 university students (63% male) from Malaysia were recruited by online and local poster advertising inviting them to complete a questionnaire containing a series of psychometric scales, including measures of 'Dark Triad' personality traits, impulsivity and cyberbullying perpetration. RESULTS: A relationship between cyberbullying perpetration and higher psychopathy scale scores was mediated by dysfunctional, but not functional, impulsivity. The relationship between cyberbullying and narcissism scores was not mediated by impulsivity. Higher Machiavellianism scores were similarly associated with cyberbullying, but there was no correlation at all between Machiavellianism and impulsivity scores. CONCLUSION: Our findings add to the literature by showing that not only Dark Triad scale scores are associated with cyberbullying, but that difficulty in refraining from or controlling impulsive behaviours (dysfunctional impulsivity) may be a key component in this relationship. Given that our sample was of generally well-functioning people, our findings may not extend to those with serious cyberbullying problems. Yet, they provide avenues for identifying people at risk of such behaviours before problems become well-established and call for more nuanced approaches towards understanding and intervening with problematic cyberbullying.

Chronic kidney disease (CKD) has a significant impact on sickle cell disease (SCD) morbidity and mortality. Early identification of individuals at highest risk of developing CKD may allow therapeutic intervention to prevent worse outcomes. This study aimed to evaluate the prevalence and risk factors for reduced estimated glomerular filtration rate (eGFR) among adults with SCD in Brazil. Participants in the REDS-III multicenter SCD cohort with more severe genotypes aged ≥ 18 years with at least two serum creatinine values were analyzed. The eGFR was calculated using the Jamaica Sickle Cell Cohort Study GFR equation. The eGFR categories were defined according to the K/DOQI. Participants with eGFR ≥ 90 were compared to those with those with eGFR < 90. Among the 870 participants, 647 (74.4%) had eGFR ≥ 90, 211 (24.3%) had eGFR 60 to 89, six (0.7%) had eGFR 30 to 59, and six (0.7%) had ESRD. Male sex (OR: 37.3; 95%CI: 22.4-65.1), higher age (OR: 1.04; 95%CI: 1.02-1.06), higher diastolic blood pressure (OR: 1.03; 95%CI: 1.009-1.06), lower Hb (OR: 0.80; 95%CI: 0.68-0.93), and lower reticulocytes (OR: 0.94; 95%CI: 0.89-0.99) levels were independently associated with eGFR < 90. There was a trend towards higher odds of death in participants with eGFR < 90 (OR: 1.8; 95%CI: 0.95-3.32; p = 0.065). In turn, participants with eGFR < 60 had a 12.2 (95%CI: 2.1-96.9) times higher odds for death when compared to those with eGFR ≥ 60. In this study, eGFR < 90 was observed in one-quarter of adults. Older age, male sex, higher diastolic blood pressure, lower hemoglobin, and lower reticulocyte levels were associated with occurrence of eGFR < 90. Estimated GFR < 60 increased the risk of mortality.

BACKGROUND: Maternal depression is a leading cause of disease burden for women worldwide; however, there are ethnic inequalities in access to psychological interventions in high-income countries (HICs). Culturally appropriate interventions might prove beneficial for African and Caribbean women living in HICs as ethnic minorities. METHODS: The review strategy was formulated using the PICo (Population, phenomenon of Interest, and Context) framework with Boolean operators (AND/OR/NOT) to ensure rigour in the use of search terms ("postpartum depression", "maternal depression", "postnatal depression", "perinatal depression" "mental health", "psychotherapy" "intervention", "treatment", "black Caribbean", "black African", "mothers" and "women"). Five databases, including Scopus, PsycINFO, Applied Social Science Index and Abstracts (ASSIA), ProQuest Central and Web of Science, were searched for published articles between 2000 and July 2020. 13 studies met the inclusion criteria, and the relevant data extracted were synthesised and thematically analysed. RESULTS: Data syntheses and analyses of included studies produced four themes, including (1) enhance parenting confidence and self-care; (2) effective mother-child interpersonal relationship; (3) culturally appropriate maternal care; and (4) internet-mediated care for maternal depression. CONCLUSION: In the quest to address maternal mental health disparities among mothers of African and Caribbean origin in HICs, the authors recommend culturally adapted psychological interventions to be tested in randomised control trials.

Mental health practitioners in many developing countries are faced with high job demands and a lack of institutional support. Given their high levels of work-related stress, it is important to identify mechanisms that help them to maintain psychological well-being and job satisfaction. Recent research has focused on the role that positive orientation (POS) may play in mediating the negative impact of stress on individual well-being. The present study investigated whether POS predicts mental health practitioners' perceived levels of stress, mental health and job satisfaction. If POS measures a person's tendency to take a positive attitude to life and their ability to cope with difficulties, a high POS could be linked to reduced levels of stress and increased levels of job satisfaction and well-being. This study examined associations between self-reported POS and psychological outcomes in a sample of 100 Malaysian mental health practitioners. The results showed that POS significantly predicted job satisfaction positively and mental health issues and perceived stress negatively, even when socio-demographic variables were controlled. Overall, we found a strong effect of POS on individual functioning across the sample of mental health practitioners. Our results have implications for improving practitioner wellbeing and job satisfaction.

BACKGROUND: Patients with sickle cell disease (SCD) often require red blood cell (RBC) transfusion for clinical complications, so may be exposed to transfusion-transmitted infections (TTIs). The prevalence of markers for human immunodeficiency virus (HIV), hepatitis C virus (HCV) and B (HBV), human T-cell lymphotropic virus (HTLV-1/2), Chagas disease, and syphilis in an SCD cohort in Brazil were studied. STUDY DESIGN AND METHODS: Clinical history, interview data, blood samples, and medical chart review data were collected during cohort enrollment from November 2013 to May 2015. Serologic markers of infection were assessed. Standard measures of statistical association were calculated, and multivariable models were developed for the most prevalent infections to identify associated factors. RESULTS: Infection markers were evident in 5.2% (144/2779) of the enrolled cohort. Anti-HCV was detected in 69 (2.5%), syphilis antibodies in 34 (1.2%), anti-HTLV-1/2 in 17 (0.6%), HBV surface antigen in 13 (0.5%), Chagas disease antibodies in 13 (0.5%), and anti-HIV in 8 (0.3%) of participants. Factors associated with increased odds of being anti-HCV reactive were older age, illegal drug use, increasing number of RBCs, more than three pain crises in the previous year, and geographic location. Syphilis was associated with older age, females, and smoking history. CONCLUSION: HCV infection was more common in older patients who may have received RBCs before testing was performed on donations, suggesting possible historic transfusion transmission. The cohort showed decreasing rates of infections and a reduction in transfusion transmission markers in younger patients compared to historical literature except for syphilis, indicating contemporary reduced risk of TTI.

BACKGROUND: Red blood cell (RBC) transfusions are used in sickle cell disease (SCD) to treat acute complications or as chronic transfusion therapy (CTT) to prevent severe manifestations. The objectives of this study were to describe blood utilization and adverse events (AEs) associated with RBCs in the Brazilian SCD population and compare characteristics of patients treated or not with CTT. STUDY DESIGN AND METHODS: A SCD cohort was established at six Brazilian centers. Medical and blood bank records were abstracted for clinical and transfusion history. Two controls not treated with CTT matched on center, SCD genotype, sex, and age were selected for each CTT case within the cohort to compare characteristics between the two groups. RESULTS: Most of the 2794-member cohort had received a transfusion (75.0% of children and 89.2% of adults) with 29.2% of patients receiving transfusion in the prior year. There were 170 (10.6%) children and 115 (9.2%) adults treated with CTT. Children not treated with CTT were more likely to have pain and acute chest hospitalizations in the prior year (25.3% vs. 11.9%, p = 0.0003; and 22.0% vs. 10.7%, p = 0.002, respectively). Both iron overload and alloimmunization were more common in CTT cases compared to controls (65.6% vs. 17.0% and 36.2% vs. 15.9%, respectively). A higher proportion of adults treated with CTT demonstrated oxygen saturation of greater than 95% compared to controls not treated (51.1% vs. 39.2%), while there was no difference in oxygenation between children treated or not. Of 4501 transfusion episodes, 28 (0.62%) AEs were reported. There was no difference in AEs associated with transfusions for acute indications versus CTT. CONCLUSION: Red blood cell transfusion was common in Brazilian SCD patients, with utilization driven by CTT. Transfusion reactions were not common; however, alloimmunization and iron overload were frequent among those on CTT, highlighting the need for novel clinical strategies to mitigate these risks.

BACKGROUND: Sickle cell disease (SCD) is a multisystem disorder characterized by a wide spectrum of clinical manifestations and severity. Studies investigating potential effects of co-morbid human immunodeficiency virus (HIV) and SCD have produced conflicting results, and additional investigations are needed to elucidate whether the interaction between the two disease states might impact both HIV and SCD clinical outcomes. The association of HIV infection with clinical and laboratory characteristics of patients with SCD was assessed. METHODS: This nested case-control study included individuals with SCD with HIV treated at six Brazilian SCD centers. Clinical and laboratory data were abstracted from medical records. HIV positive participants were compared to age, gender, center, and SCD genotype matched HIV negative participants (ratio 1:4). Individual clinical outcomes as well as a composite outcome of any SCD complication and a composite outcome of any HIV-related complication were compared between the two groups. RESULTS: Fifteen HIV positive participants were included, 12 (80%) alive and 3 (20%) deceased. Most of the HIV positive patients had HbSS (60%; n = 9), 53% (n = 8) were female, and mean age was 30 ± 13 years. The frequency of individual SCD complications of acute chest syndrome/pneumonia, sepsis/bacteremia, pyelonephritis, ischemic stroke, hemorrhagic stroke, abnormal transcranial Doppler (TCD), and pulmonary hypertension was higher in HIV positive participants when compared to HIV negative, although analyzed individually none were statistically significant. HIV positive participants had significantly higher risk of any SCD complication and of a composite HIV-related complication compared to the HIV negative group (HR = 4.6; 95%CI 1.1-19.6; P = 0.04 and HR = 7.7; 95%CI 1.5-40.2; P = 0.02, respectively). There was a non-significant trend towards higher risk of any infections in participants with HIV positive (HR = 3.5; 95%CI 0.92-13.4; P = 0.07). Laboratory parameters levels were not significantly different in individuals with and without HIV. CONCLUSIONS: In summary, our study in SCD patients shows that those with HIV have an increased risk of any SCD complication and HIV-related complications, as well as a suggestive but not significantly increased risk of infections.

We described the clinical, laboratory and molecular characteristics of individuals with Hb S (HBB: c.20A>T)/ß-thalassemia (Hb S/ß-thal) participating in the Recipient Epidemiology and Donor Evaluation Study (REDS-III) Brazil Sickle Cell Disease cohort. HBB gene sequencing was performed to genotype each ß-thal mutation. Patients were classified as Hb S/ß0-thal, Hb S/ß+-thal-severe or Hb S/ß+-thal based on prior literature and databases of hemoglobin (Hb) variants. Characteristics of patients with each ß-thal mutation were described and the clinical profile of patients grouped into Hb S/ß0-thal, Hb S/ß+-thal and Hb S/ß+-thal-severe were compared. Of the 2793 patients enrolled, 84 (3.0%) had Hb S/ß0-thal and 83 (3.0%) had Hb S/ß+-thal; 40/83 (48.2%) patients with Hb S/ß+-thal had mutations defined as severe. We identified 19 different ß-thal mutations, eight Hb S/ß0-thal, three Hb S/ß+-thal-severe and eight Hb S/ß+-thal. The most frequent ß0 and ß+ mutations were codon 39 (HBB: c.118C>T) and IVS-I-6 (T>C) (HBB: c.92+6T>C), respectively. Individuals with Hb S/ß0-thal had a similar clinical and laboratory phenotype when compared to those with Hb S/ß+-thal-severe. Individuals with Hb S/ß+-thal-severe had significantly lower total Hb and Hb A levels and higher Hb S, white blood cell (WBC) count, platelets and hemolysis markers when compared to those with Hb S/ß+-thal. Likewise, individuals with Hb S/ß+-thal-severe showed a significantly higher occurrence of hospitalizations, vaso-occlusive events (VOE), acute chest syndrome (ACS), splenic sequestration, blood utilization, and hydroxyurea (HU) therapy.

Sickle cell disease (SCD) is associated with significant morbidity, and allogeneic hematopoietic stem cell transplantation (HSCT) remains the primary curative treatment. Recently, the Brazilian Ministry of Health released a regulation that required the publically funded healthcare system to pay for HSCT for SCD patients with defined indications. We used an existing 2794-member SCD cohort established during 2013 to 2015 to characterize candidates for HSCT and estimate the number of possible donors. Of 2064 patients with SC anemia (SCA), 152 of 974 children (16%) and 279 of 1090 adults (26%) had at least 1 HSCT indication. The most common indication for transplant was stroke (nâ¯=â¯239) followed by avascular necrosis (nâ¯=â¯96), priapism (nâ¯=â¯82), cerebrovascular disease (nâ¯=â¯55), >2 vaso-occlusive episodes (nâ¯=â¯38), alloantibodies and chronic transfusion therapy (nâ¯=â¯18), and >2 acute chest syndrome episodes (nâ¯=â¯11). Increasing age, number of transfusions, abnormal transcranial Doppler, retinopathy, dactylitis, and use of hydroxyurea were more frequent in the 152 children with an indication for HSCT compared with 822 without (P < .001). Of 152 children and 279 adults meeting the eligibility definition, 77 (50%) and 204 (73%), respectively, had at least 1 non-SCD full sibling who could potentially serve as a donor. In conclusion, in a large cohort of SCA patients, 16% of children and 26% of adults had at least 1 indication for HSCT; these indications were associated with the severity of the disease. This study provides clinical data necessary for estimating the costs and infrastructure that would be required to implement HSCT in a public healthcare system.

INTRODUCTION: Priapism is the persistent and painful erection of the penis and is a common sickle cell disease (SCD) complication. AIM: The goal of this study was to characterize clinical and genetic factors associated with priapism within a large multi-center SCD cohort in Brazil. METHODS: Cases with priapism were compared to SCD type-matched controls within defined age strata to identify clinical outcomes associated with priapism. Whole blood single nucleotide polymorphism genotyping was performed using a customized array, and a genome-wide association study (GWAS) was conducted to identify single nucleotide polymorphisms associated with priapism. MAIN OUTCOME MEASURE: Of the 1,314 male patients in the cohort, 188 experienced priapism (14.3%). RESULTS: Priapism was more common among older patients (P = .006) and more severe SCD genotypes such as homozygous SS (P < .0001). In the genotype- and age-matched analyses, associations with priapism were found for pulmonary hypertension (P = .05) and avascular necrosis (P = .01). The GWAS suggested replication of a previously reported candidate gene association of priapism for the gene transforming growth factor beta receptor 3 (TGFBR3) (P = 2 × 10-4). CLINICAL IMPLICATIONS: Older patients with more severe genotypes are at higher risk of priapism, and there is a lack of consensus on standard treatment strategies for priapism in SCD. STRENGTHS & LIMITATIONS: This study characterizes SCD patients with any history of priapism from a large multi-center cohort. Replication of the GWAS in an independent cohort is required to validate the results. CONCLUSION: These findings extend the understanding of risk factors associated with priapism in SCD and identify genetic markers to be investigated in future studies to further elucidate priapism pathophysiology.

Sickle cell disease (SCD) affects more than 13 million people and can have a significant impact on the quality of life (QoL) of those persons. We performed a cross-sectional study to evaluate the QoL in SCD children 8-12 years old enrolled from November 2014 to March 2016 in a large multicenter cohort study in Brazil. The PedsQL™ SCD Module was used to evaluate QoL in 412 children from six Brazilian health centers. The mean age of participants was 10.5 years and 193(46.7%) were women. The mean global score was 60.7, with a Cronbach´s alpha of 0.92. There were significant differences in socioeconomic demographics and treatments among participants at the six centers, but age, income, SCD genotype, and use of hydroxyurea did not significantly affect the QoL scores. After adjustment for all of these variables in a linear regression model, a significant difference was observed by site in global QoL score and the dimensions 'worry II'(ß0 = 20.7, p < .00), 'treatment´(ß0 = 66.8, p < .00) and communication II'(ß0 = 45.8, p < .00). These dimensions are affected by the capacity of health professionals to provide clinical and psychological support to patients. Our results suggest that QoL of this patient population varied according the health center even adjusted by sociodemographics characteristics. Additional training of health professionals in psychological and clinical support could directly reduce patient apprehension about the disease its clinical complications.

Although faced with historical and ongoing hardships, many indigenous communities in Southeast Asia have managed to survive and thrive. The identification of factors that assist these communities in coping with the challenges experienced would help enhance their overall psychological well-being and resilience. The current review outlines types of protective factors for the indigenous communities in Southeast Asia focusing on the cultural, family and community elements linked to their psychological well-being. Four themes of protective factors were identified strong connection to the land and the environment, embracing cultural norms and traditions, passing down and keeping indigenous knowledge across generations, and emphasis on community and social cohesion. Findings suggest that the value of interconnectedness serves as an overarching theme that forms the worldview of the indigenous communities in Southeast Asia. Interconnectedness was important to the indigenous peoples as they considered themselves to be extensions of their family, community, ancestors, future descendants, the land and to all living things and creations that reside on their lands. Future intervention attempts to promote resilience among these communities should take these factors into account, and pay closer attention to community-level factors that seem to have a profound impact on the indigenous construction of resilience.

Approximately 3500 children with sickle cell disease (SCD) are born in Brazil each year, but the burden of SCD morbidity is not fully characterised. A large, multi-centre cohort was established to characterise clinical outcomes in the Brazilian SCD population and create the infrastructure to perform genotype-phenotype association studies. Eligible patients were randomly selected from participating sites and recruited at routine visits. A biorepository of blood samples was created and comprehensive demographic and clinical outcome data were entered in a centralized electronic database. Peripheral blood genome-wide single nucleotide polymorphism (SNP) genotyping was performed using a customized Transfusion Medicine (TM) Array. A total of 2795 participants at six Brazilian sites were enrolled between 2013 and 2015. The cohort included slight predominance of children <18 years (55·9%) and females (53·0%). Haemoglobin (Hb) SS was the most common SCD genotype (70·7%), followed by HbSC (23%), Sß0 (3·0%) and Sß+ (2·9%). SNP data from the TM Array were analysed to evaluate the genetic ancestry of the cohort and revealed significant admixture among the population. Demographics and clinical complications, stratified by age and SCD genotype, are summarized and future studies in this cohort are discussed.

Past research on healthy lifestyle behaviours has been primarily conducted within Western or Judeo-Christian contexts, while non-Western or Muslim contexts remain under-represented. This study examined predictors of healthy lifestyle behaviours (religiosity, goal-setting, impulse control, and subjective well-being) in Malaysian Muslims and explored the mechanisms underlying the relationship between religiosity and healthy lifestyle behaviours. Self-report survey responses from 183 healthy adults (M age = 28.63 years, 18-50 years) were analysed using regression and multiple mediation analyses. The results indicated that subjective well-being emerged as the strongest predictor, followed by goal-setting. Furthermore, subjective well-being and goal-setting mediated the religiosity-healthy lifestyle behaviour relationship. The findings provide guidance for future health-promoting interventions.

BACKGROUND AND OBJECTIVES: Historically, aging research has focused primarily on health deterioration and negative aspects associated with aging. This has limited the scope of our understanding of the experience of aging and the relationships between aging and well-being from an integrative biopsychosocial perspective. In the same vein, there is a lack of reliable and valid assessments of aging that capture the positive aspects that characterize and improve the subjective experience of this period of life, particularly one that focuses on psychosocial well-being, including meaningful experiences and activities, group memberships, general abilities. This study presents the development and validation of the Positive Aging Scale (PAS), a novel self-report assessment. RESEARCH DESIGN AND METHODS: This was an online cross-sectional study conducted on 501 UK-residents aged ≥ 60 years. A number of self-reported items and measures of positive aging, general health, well-being, and cognitive functioning were administered to the sample. We used exploratory and confirmatory factor analyses and assessed the dimensionality, reliability, and concurrent criterion-related validity of the PAS. RESULTS: The results suggested that a unidimensional solution represents the data well, with the positive aging factor adequately loading on eight items, and the solution showing factorial invariance between young-old and old participants (i.e., ≥ 75 years). Total PAS scores positively correlate with general health, well-being, and cognitive functioning. DISCUSSION AND IMPLICATIONS: The PAS demonstrated strong psychometric properties and the findings highlight correlations between the PAS and key outcomes of positive aging, including general health. Implications for research and interventions are discussed.
RESUMO
The study aimed to explore the associations between the psychosocial and organizational factors, job satisfaction, and mental well-being of schoolteachers. A further aim was to examine whether job satisfaction mediated the relationship between these factors and mental well-being. A cross-sectional design was used to collect data using a self-reported questionnaire. Six hundred and nine schoolteachers were included in the final analyses. The relationships between the variables were tested in a path analysis model. The data fit the hypothesized model well. The results demonstrated that organizational justice, efficacy beliefs, and school climate were significantly associated with job satisfaction and that the relationships between these variables and mental well-being were mediated by job satisfaction. The findings have implications for programs targeted at promoting teachers' well-being.

Manifestations of sickle cell disease (SCD) begin early in childhood and cause morbidity and decreased life expectancy. Hematopoietic stem cell transplantation (HSCT) is curative but associated with risk of mortality attributable to the transplant. This risk should be counterbalanced with SCD morbidity and mortality. A severity score using a Bayesian network model was previously validated to predict the risk of death in adult individuals with SCD. The objective of this study is to calculate the severity scores of participants in a multicenter cohort of Brazilians with SCD, using a previously published Bayesian network-derived score, associated with risk of death and then compare the severity scores between participants with and without an indication for HSCT as defined by the Brazilian Ministry of Health (MoH) criteria. This is an observational, retrospective study. We analyzed 2063 individuals with sickle cell anemia from the Recipient Epidemiology and Donor Evaluation Study-III Brazil SCD cohort and applied a Bayesian network-derived score to compare candidates and non-candidates for HSCT according to the Brazilian MoH transplant criteria. Classical statistical methods were used to analyze data and make comparisons. We compared severity scores between cohort members with (n = 431) and without (n = 1632) HSCT indications according to Brazilian MoH. Scores were not different in adult participants with ≥1 HSCT indication when compared to those with no indication (mean 0.342 versus 0.292; median 0.194 versus 0.183, P = .354) and receiver operating characteristic curves did not demonstrate an obvious threshold to differentiate participants with or without HSCT indications. Severity score may predict risk of death but does not differentiate HSCT candidates. Current indications should be evaluated to ensure that patients with more severe disease who might benefit from HSCT are appropriately identified.

Serum sickness is an immune-complex-mediated illness that frequently occurs in patients after polyclonal antibody therapy (thymoglobulin). Although serum sickness has been described secondary to thymoglobulin therapy in adults, there are no reports in children on thymoglobulin-induced acute renal failure. We report a case of serum sickness in a 10-year-old girl who was treated for severe aplastic anemia using rabbit antithymocyte globulin (ATG). Eleven days after being started on antithymocyte globulin treatment, she developed fever, gross hematuria, arthralgia, rash, and acute renal failure. Laboratory results showed decreased complement levels, hypergammaglobulinemia, serum creatinine of 4.8 mg/dL (0.6 mg/dL at baseline), and blood urea nitrogen of 79 mg/dL (28 mg/dL at baseline). Peritoneal dialysis was required for 14 days. The patient's symptoms resolved after 13 days on treatment with a short course of high-dose steroids for 3 days, followed by a prednisolone taper. Early recognition and accurate diagnosis is the key for managing thymoglobulin-induced serum sickness, as treatment is highly effective at achieving good outcomes.

BACKGROUND: The aim of this study was to evaluate the effectiveness and safety of intravenous ketamine-propofol admixture ("ketofol") in the same syringe for procedural sedation and analgesia in children undergoing bone marrow aspiration. METHODS: This was a prospective, observational pilot study. Patients aged between 4 and 12 years requiring sedation for bone marrow aspiration were included. Ketofol (1:1 mixture of ketamine 10 mg/mL and propofol 10 mg/mL) was given intravenously in 0.5 mg/kg aliquots each with a 1-min interval and titrated to reach sedation levels of 3 or 4 (Ramsay score). The primary outcome was patient satisfaction with the degree of sedation. Secondary outcomes included injection pain, total sedation time, recovery time, hemodynamic and respiratory parameters, and adverse events. RESULTS: A total of 20 patients were enrolled in the study. The median total dose of ketofol administered was 1.25 mg/kg each of propofol and ketamine (95%CI 0.77-2 mg/kg). The median score on the visual analog scale was 0 (extremely comfortable) (0-1.5; 95%CI 0.2-2.2). Median recovery time was 23 min (20.5-28 min; 95%CI 17.1-51.2). The incidence of injection pain was 2/20. Two patients had transient diplopia and one child reported dreams. No patients had hypotension, vomiting or required airway intervention. CONCLUSION: Ketofol provided effective sedation, which was reflected in the high degree of satisfaction recorded by children requiring procedural sedation and analgesia for bone marrow aspiration. We also observed rapid recovery and no clinically significant complications. A large number of patients is required to evaluate and validate these findings.

Coronavirus disease 2019 (COVID-19) outbreak has led to the closure of schools and universities, which forced students to reorganize their daily and academic lives. The pandemic has thus impacted the well-being of students in various ways. This study aimed to investigate the relationship between the perceived employability, self-efficacy, ambition, organizational commitment, and career planning of students, as well as mental well-being, student engagement, and academic burnout during the pandemic. A total of 269 Italian university students participated in an online questionnaire. Our results highlight that students experienced high levels of uncertainty about their employability and career planning. In contrast, however, they reported healthy levels of mental well-being and student engagement, high career ambitions, and strong self-efficacy, despite the impact of COVID-19. We suggested that intervention and supportive programs should be offered to students over the long term in order to minimize the negative impact of the pandemic.
