Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

Transtorno de déficit de atenção e hiperatividade na vida adulta : estudo sobre o curso e seus moderadores a partir de um seguimento de sete anos

O conhecimento sobre o curso dos transtornos mentais durante a vida e os fatores que influenciam o seu comportamento fazem parte das primeiras informações buscadas por pacientes e por profissionais de saúde, objetivando um melhor planejamento e intervenções mais acuradas. No caso do Transtorno de Déficit de Atenção e Hiperatividade (TDAH), as informações existentes limitam-se a responder sobre o prognóstico do TDAH para amostras de crianças e adolescentes. Estudos longitudinais prospectivos a partir de amostras clínicas de adultos possuem um delineamento capaz de trazer informação sobre o comportamento do TDAH durante a vida adulta. A amostra de Porto Alegre de adultos com TDAH, coletada nos últimos 12 anos no ambulatório de TDAH em adultos do HCPA, possui extensa caracterização em nível fenotípico e genético. O objetivo principal deste trabalho é investigar em pacientes adultos o curso do TDAH e as características sociais e psiquiátricas envolvidas em sua trajetória, sete anos após a avaliação inicial. Para isso, foram realizados dois estudos a fim de observar o comportamento do transtorno e dos seus domínios durante a vida adulta. O primeiro artigo investiga a persistência do diagnóstico formal do TDAH e a possibilidade de remissão completa sete anos após a primeira avaliação. Mesmo após o período de maior neurodesenvolvimento cerebral, e independentemente da idade dos indivíduos, em torno de 30% da amostra perdeu o diagnóstico do transtorno. A remissão completa ocorreu em 12.4% dos pacientes. Indivíduos com diagnóstico de TOD e Fobia Social, maior número de sintomas de hiperatividade/impulsividade e os que se apresentavam no maior quartil de desatenção durante a avaliação inicial persistiram mais frequentemente com o diagnóstico. Nível de prejuízo pelo TDAH, gênero e tempo de uso de metilfenidato não tiveram efeito significativo. No segundo artigo, analisamos separadamente o comportamento dos dois domínios do TDAH e os possíveis moderadores do seu curso, incluindo o efeito de um grupo de sintomas sobre o outro. Diferentemente dos resultados encontrados nos estudos que avaliaram os períodos da infância e adolescência, os sintomas de hiperatividade/impulsividade declinaram na mesma proporção que os de desatenção. A análise dos domínios individualmente também permitiu identificar que cada grupo de sintomas possui moderadores distintos. O declínio dos sintomas de desatenção foi menor nos pacientes com história de suspensão escolar, enquanto que a hiperatividade/impulsividade declinou menos nos indivíduos que possuem história de problemas com álcool e maior número de sintomas de desatenção. A partir dos resultados encontrados e da literatura existente, esta Tese propõe questionamentos sobre variáveis que podem influenciar o curso do TDAH na vida adulta, bem como perspectivas para intervenções preventivas.A better comprehension regarding the course of mental disorders across the lifespan and the factors that influence its trajectory are among the first goals sought by patients and health professionals in the intent to improve planning and interventions. In the case of Attention Deficit/Hyperactivity Disorder (ADHD), prognosis information is limited to data derived from samples of children and adolescents. Prospective longitudinal studies from clinical samples of adults have the appropriate design to provide information of ADHD trajectory during adulthood. The Porto Alegre sample of adults with ADHD, collected over the past 12 years at the ADHD Outpatient Program – Adult division at the Hospital de Clínicas de Porto Alegre (HCPA), has an extensive phenotypic characterization and genetic level. The main goal of this work is to investigate the course of ADHD, as well as other psychiatric and social characteristics involved in its trajectory, in a sample of adult patients seven years after the initial assessment. For this purpose, two studies were conducted to examine the course of the disorder and its domains during adulthood. The first paper investigates the persistence of formal ADHD diagnosis and the possibility of complete remission seven years after the first evaluation. It shows that, even after the most intense period of brain neurodevelopment, and regardless of the age of the individuals, around 30% of the sample no longer fulfilled the diagnostic criteria for the disorder. Complete remission occurred in 12.4% of patients. Individuals diagnosed with Oppositional Defiant Disorder and Social Phobia, with more symptoms of hyperactivity/impulsivity and those who performed in the top quartile of inattention symptoms during the initial evaluation were more likely to persist with the diagnosis. Level of impairment due to ADHD symptoms, gender and the extent of methylphenidate use (months) had no significant effect. In the second article, the trajectory of the two ADHD domains (inattention and hyperactivity/impulsivity), along with their possible moderators, were analysed separately. Differently from the results found by studies evaluating the course of ADHD domains during childhood and adolescence, this study indicated that symptoms of hyperactivity/impulsivity declined in the same proportion as inattention during adulthood. The analysis of the two ADHD domains separately also identified that each group of symptoms has distinct moderators. The decline of inattention symptoms was lower in patients with a history of school suspension, whereas hyperactivity/impulsivity decline was lower in individuals with a history of problems with alcohol use and more symptoms of inattention. Based on the overall results and the existing literature, this Thesis raises questions about characteristics that may influence the course of ADHD during adulthood, as well as perspectives for preventive interventions
