Time-of-Day Adrenal Modulation of Corticosterone Synthesis is Affected by Sex and Diet but Not by Proanthocyanidins in Rat.

SCOPE: The aim of this study is to investigate the effect of time-of-day on serum hormones and gene expression in adrenal glands, studying the impact of sex, obesogenic diet, and timing of proanthocyanidins administration, with a focus on glucocorticoids synthesis by this gland. METHODS AND RESULTS: Female and male rats, assigned to a standard chow or a cafeteria diet-fed group, receive a daily oral dose of a grape seed proanthocyanidin extract (GSPE), or a vehicle (when light is turned on, or when light is turned off). Corticosterone, estradiol, and testosterone serum levels, and the expression analysis of clock genes and genes related to corticosterone synthesis pathway, are assessed. Serum hormone levels exhibited a marked time-of-day effect also see in the expression of scavenger receptor class B member 1 (Scarb1) and cyp11b genes. The correlation between these two genes and period circadian regulator 2 (Per2) is also extended to other clock genes, although to a lesser extent: cryptochrome (Cry) and nuclear receptor subfamily 1 group D member 1 (Rev-erba). CONCLUSION: The strong correlations found suggest an important role of local Per2 (but also of Cry and Rev-erbA) in regulating the expression of the enzymes involved in the corticosterone synthesis pathway. The expression of clock genes in adrenals is influenced by sex and diet but not by GSPE.

Effectiveness of internet-delivered psychological treatments for children and adolescents with anxiety and/or depressive disorders: Systematic review and network meta-analysis.

Background: Anxiety and depression symptomatology has increased in the child and adolescent population. Internet-delivered psychological treatments (IDPT) can help to reduce this symptomatology, attending to the largest possible population. Aim: To conduct a systematic review and network meta-analysis of IDPT to reduce anxiety and depression symptoms in children and adolescents. Methods: The search for studies was conducted in SCOPUS, PsycINFO, PSICODOC, PsycARTICLES and Medline, between 2000 and 2022, in December 2022. Studies were selected if they were conducted with a sample of children and/or adolescents with previous symptoms of anxiety and depression, had applied IDPT, and included at least two comparative groups with pretest-posttest measures. Network meta-analyses were separately performed for anxiety and depression outcomes. Publication bias was analyzed using Egger's test and funnel plots, and mixed-effects meta-regression models were applied to account for heterogeneity. Results: 37 studies were included in the meta-analysis, providing a total of 74 comparative groups. IDPT exhibited low-to-moderate, statistically significant average effect sizes when compared to both inactive and active controls. No statistical significance was found when IDPT was compared with other types of interventions. Discussion: IDPT is recommended to reduce anxiety and depression symptomatology in children and adolescents, but more studies are needed which compare treatments with other types of interventions, such as face-to-face therapy.

Ibero-American Consensus for the Management of Peritoneal Sarcomatosis: Updated Review and Clinical Recommendations.

Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis. A multidisciplinary working group of experts in sarcomas and peritoneal oncological surgery established a series of recommendations based on current scientific evidence for the management of peritoneal sarcomatosis, taking into account the different histological subgroups of abdominopelvic sarcomas that can cause it depending on their origin: retroperitoneal sarcomas, uterine sarcomas, and visceral/peritoneal sarcomas of GIST (gastrointestinal stromal tumor) and non-GIST origin. This article shows the results of sarcoma experts' voting on the recommendations presented during the I Ibero-American Consensus on the Management of Peritoneal Sarcomatosis, which took place during the recent celebration of the III Hispanic-Portuguese Meeting for Updates on the Treatment of Sarcomas.

Pd-Catalyzed Ring-Opening Polymerization of Cyclobutanols through C(sp3)-C(sp3) Bond Cleavage.

A new approach to ring-opening polymerization (ROP) based on C(sp3)-C(sp3) bond cleavage is reported. This process is based on the ability of Pd to promote both the ß-carbon elimination of a bifunctional cyclobutanol precursor and the C-C coupling process with the resulting Pd-alkyl intermediate. Consequently, novel polyketone materials are obtained. Owing to the modular synthesis of the used cyclobutanol monomers, the present ROP reaction allows the introduction of substitution patterns in the polymeric chain that are not accessible by current polyketone synthesis methodologies. We have explored in detail the initiation, propagation, and termination steps of this new polymerization process.

Radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal sarcomatosis: Results from a reference center and considerations based on current evidence.

INTRODUCTION: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence. METHODS: Study on a prospective database of patients with peritoneal sarcomatosis who underwent CRS and HIPEC, from 2016 to 2022, in a national reference center for sarcomas and peritoneal oncological surgery, who met the established inclusion/exclusion criteria. RESULTS: 23 patients were included in the study, with a median age of 53 years (6-68). Recurrent/persistent clinical presentation predominated (78.3%). Visceral origin (including GIST and non-GIST peritoneal) accounted for 47.8% of patients, compared to 43.5% uterine and 8.7% retroperitoneal. The median PCI was 17 (3-36), with CC0 cytoreduction of 87%. Postoperative morbidity (Dindo Clavien III-IV) of 13%, with no postoperative mortality in the series. Overall survival and disease-free survival at 5 years were 64% and 34%, respectively. Histological grade was the most influential prognostic factor for survival. CONCLUSIONS: The results of the series, with low morbidity, support the benefit of radical peritoneal oncological surgery in patients with peritoneal sarcomatosis after adequate selection, as long as it is performed in high-volume centers, experienced surgeons and expert multidisciplinary teams. However, the role of HIPEC remains to be demonstrated and pending future studies.

Assessment of the Effects of Physiotherapy on Back Care and Prevention of Non-Specific Low Back Pain in Children and Adolescents: A Systematic Review and Meta-Analysis.

Non-specific low back pain (NSLBP) in children and adolescents has increased in recent years, and the evidence of the physiotherapy interventions in back care needs to be updated. Our main goal was to quantify the effects of preventive physiotherapy interventions on improving behavior and knowledge related to back care and prevention of NSLBP in children and adolescents. Based on two previous meta-analyses, Cochrane Library, MEDLINE, PEDro, Web of Science, LILACS, IBECS, PsycINFO, and IME databases and several journals were searched. Two researchers independently extracted data and assessed the risk of bias in the studies using the RoB2 tool. Data were described according to PRISMA guidelines. A total of 24 studies (28 reports) were included. In the posttest, the behavior variable obtained an overall effect size of d+ = 1.48 (95%CI: 0.40 to 2.56), and the knowledge variable obtained an effect size of d+ = 1.41 (95%CI: 1.05 to 1.76). Physiotherapy has demonstrated beneficial impacts on behavior and knowledge concerning back care and to prevent NSLBP in children and adolescents. Interventions focusing on postural hygiene and exercise should be preferred, especially those that are shorter in number of weeks, more intense, and incorporate as many intervention hours as possible.

Transparency in Cognitive Training Meta-analyses: A Meta-review.

Meta-analyses often present flexibility regarding their inclusion criteria, outcomes of interest, statistical analyses, and assessments of the primary studies. For this reason, it is necessary to transparently report all the information that could impact the results. In this meta-review, we aimed to assess the transparency of meta-analyses that examined the benefits of cognitive training, given the ongoing controversy that exists in this field. Ninety-seven meta-analytic reviews were included, which examined a wide range of populations with different clinical conditions and ages. Regarding the reporting, information about the search of the studies, screening procedure, or data collection was detailed by most reviews. However, authors usually failed to report other aspects such as the specific meta-analytic parameters, the formula used to compute the effect sizes, or the data from primary studies that were used to compute the effect sizes. Although some of these practices have improved over the years, others remained the same. Moreover, examining the eligibility criteria of the reviews revealed a great heterogeneity in aspects such as the training duration, age cut-offs, or study designs that were considered. Preregistered meta-analyses often specified poorly how they would deal with the multiplicity of data or assess publication bias in their protocols, and some contained non-disclosed deviations in their eligibility criteria or outcomes of interests. The findings shown here, although they do not question the benefits of cognitive training, illustrate important aspects that future reviews must consider.

A systematic review and network meta-analysis on the effectiveness of exercise-based interventions for reducing the injury incidence in youth team-sport players. Part 2: an analysis by movement patterns.

The objectives of this network meta-analysis were: (a) to estimate and compare the pooled effects of some injury prevention programs (IPPs) whose exercise-based components were categorized using a movement pattern-specific taxonomy on reducing overall and some specific body regions (lower extremity, thigh, knee, and ankle) injury incidences in youth team sport athletes and (b) to explore the individual effects of these components on the injury incidence rates (IIRs) previously mentioned. Searches were performed in PubMed, Web of Science, SPORTDiscus, and Cochrane Library. Eligible criteria were: exercise-based interventions comprised of exercises involving athletic motor skill competencies and evaluated against a control group, overall IIRs were reported, and youth (≤19 years old) team sport players. For the current analysis, a taxonomy based on movement patterns was employed for exercise component identification (upper body pushing and pulling; lower body concentric and eccentric; core; mechanics; acceleration; and lower body stability). Pooled effects were calculated by frequentist random effects pairwise and network meta-analyses. Nineteen studies were included. Most of the IPPs exhibit risk reduction when compared to their control groups on overall, lower extremity, and ankle injuries. Interventions comprised of lower body concentric and eccentric, core, mechanics, and lower body stability exercises were the most effective measures for reducing these injuries. None of the IPPs demonstrated to be effective for reducing thigh injuries, and contradictory results were found for knee injuries. Individual analysis at component level revealed that the lower body (bilateral and unilateral, concentric, and eccentric) component was the only one associated with a significant reduction on overall injuries. Indirect evidence suggests that interventions incorporating lower body concentric and eccentric, core, mechanics, and lower body stability exercises might be the most effective for reducing overall, lower extremity, and ankle injuries in youth team sports.

The categorization of exercise components based on the movement patterns might, a priori, be considered a criterion more closely associated with the injury phenomenon.Lower body concentric and eccentric, core, mechanics, and lower body stability exercises should be incorporated to any training program aimed at minimizing the risk of injury in youth.The ineffectiveness of interventions on the reduction of thigh injuries reveals the need for reconsideration of injury prevention strategies.

Pd-Catalyzed Formal [2 + 2]-Retrocyclization of Cyclobutanols via 2-Fold Csp3-Csp3 Bond Cleavage.

In this work, we describe the unexpected 2-fold Csp3-Csp3 bond cleavage suffered by cyclobutanols in the presence of a catalytic amount of Pd(OAc)2 and promoted by the bulky biaryl JohnPhos ligand. Overall, the sequential cleavage of a strained and an unstrained Csp3-Csp3 bond leads to the formal [2 + 2]-retrocyclization products, namely, styrene and acetophenone derivatives. This procedure might enable the use of cyclobutanols as masked acetyl groups, resisting harsh conditions in organic synthesis.

Obesity and overweight as risk factors for low back pain in children and adolescents: a meta-analysis.

BACKGROUND: Childhood obesity and overweight are associated with musculoskeletal pain, but the association between low back pain (LBP) and overweight/obesity in this population needs clarification. The objective of this meta-analysis is to ascertain the relationship between LBP and obesity/overweight in children and adolescents. METHODS: Various databases and specialized journals were queried from inception to October 2022. Encompassed were all studies examining the association between overweight or obesity and LBP among participants aged 6 to 18 years. The ROBINS-E tool was employed to assess bias. Random-effects models were used to pool results across studies, with location-scale models used to search for moderator variables where evidence of heterogeneity was found. RESULTS: In total, 34 studies were incorporated. Four studies had a low risk of bias, while the remaining studies had some concerns. Nine studies evinced an association between overweight and LBP, in contrast to normal weight, yielding an OR of 1.13 (95% CI 1.10-1.16) and no heterogeneity. Eight studies demonstrated a similar association between obesity and LBP compared to normal weight, with an OR of 1.27 (95% CI 1.20-1.34) and no heterogeneity. Ten studies established an association between overweight/obesity and LBP compared to normal weight, yielding an OR of 1.18 (95% CI 1.14-1.23) and no heterogeneity. Finally, nineteen studies showcased an association between body mass index (BMI) and LBP, with an OR of 1.19 (95% CI 1.03-1.39) with evidence of heterogeneity. For this last analysis, we compared the mean BMI in groups and transformed results to log OR, and then retransformed to OR. CONCLUSION: Overweight and obesity may be risk factors for LBP in children and adolescents. The association between LBP and obesity appears to be stronger than with overweight. However, the analysis revealed considerable heterogeneity and risk of bias across studies.

Administration time effect of dietary proanthocyanidins on the metabolome of Fischer 344 rats is sex- and diet-dependent.

Proanthocyanidins (PAs) are one of the most commonly ingested polyphenols in the human diet, with a wide range of beneficial health effects. Remarkably, PAs have been reported to influence core and peripheral clock genes expression, and their effects may change in a time-of-day dependent manner. Therefore, the aim of this study was to investigate whether the capacity of PAs to modulate the metabolome is conditioned by the time-of-day in which these compounds are consumed in a diet- and sex-dependent manner. To do this, a grape seed proanthocyanidin extract (GSPE) was administered to female and male Fischer 344 rats at ZT0 (in the morning) and ZT12 (at night) and the GSPE administration time effect was evaluated on clock genes expression, melatonin hormone and serum metabolite levels in a healthy and obesogenic context. The results showed an administration time effect of GSPE on the metabolome in a sex and diet-dependent manner. Specifically, there was an effect on amino acid, lipid and cholate metabolite levels that correlated with the central clock genes expression. Therefore, this study shows a strong influence of sex and diet on the PAs effects on the metabolome, modulated in turn by the time-of-day.

Immune dysregulation, autoimmunity, and granule defects in gray platelet syndrome.

Since the description of the first case with gray platelet syndrome (GPS) in 1971, this rare inherited platelet disorder has been the focus of extensive clinical and basic research. These studies have not only increased our knowledge about the clinical manifestations of GPS but also deepened our understanding of the biogenesis of platelet α-granules and their pathophysiology in hemostasis and thrombosis. The discovery of the causal gene, neurobeachin-like 2, in 2011 was a milestone in hematology. Following this was the rapid diagnosis and phenotyping of many new patients and the further development of experimental models to characterize the pathophysiological relevance of neurobeachin-like 2 in hemostasis and immunity. The impact of altered protein function on cells other than platelets became apparent, including defects in the granules of neutrophils and monocytes and changes in the transcriptomic and proteomic profiles of other immune cells such as T lymphocytes. Besides the previously recognized clinical manifestations of macrothrombocytopenia, splenomegaly, and early-onset bone marrow fibrosis, we now recognize that immunologic abnormalities, including autoimmune diseases and recurrent infections, affect a proportion of patients with GPS. There is a proinflammatory signature of the plasma in GPS, with quantitative alterations of multiple proteins, including many produced by the liver. This review will cover the classical features of GPS and then focus on additional clinical manifestations of immune dysregulation and cellular defects beyond platelets in patients with this rare disorder.

Resultados obtenidos tras el tratamiento quirúrgico de los pacientes con metástasis hepáticas de sarcomas / Surgical and oncological results after surgical treatment of patients diagnosed with sarcoma liver metastases

Introducción: La presencia de metástasis hepáticas en pacientes con sarcomas se asocia a peor pronóstico, aunque en casos seleccionados la resección de dichas metástasis se ha propuesto para aumentar la supervivencia. El objetivo de este estudio es describir la evolución postoperatoria y los resultados oncológicos tras la resección hepática. Métodos: Se presenta un estudio retrospectivo unicéntrico. Se incluyen pacientes diagnosticados de metástasis hepáticas de sarcoma intervenidos quirúrgicamente entre 2003-2019. Los criterios de inclusión fueron la presencia de enfermedad resecable, la presencia de enfermedad extrahepática controlada no se consideró criterio de irresecabilidad. Resultados: Diecinueve pacientes se sometieron a resección hepática de 7 tipos distintos de estirpes sarcomatosas. La mediana de edad fue de 58 años. Las metástasis se diagnosticaron 25 meses de mediana tras el primario, 6 (32%) presentaron lesiones sincrónicas y 12 (63%) estaban afectos de enfermedad extrahepática. Se realizó hepatectomía mayor en 5 (26%) pacientes; se describieron 8 (42%) complicaciones menores. La mediana de seguimiento fue de 33 meses. El análisis de supervivencia se realizó estratificando en 2 grupos, la supervivencia fue del 100%, 85,7% y del 42,9% al año, a los 3 años y a los 5 años, en los no-GIST, y del 100% y del 40% a los 5 y 10 años en los GIST. Conclusiones: El abordaje quirúrgico de las metástasis hepáticas de sarcoma parece aumentar la supervivencia en pacientes seleccionados, asociando pocas complicaciones. En nuestra serie, la tasa de enfermedad extrahepática es elevada en comparación con series previas, no obstante la supervivencia es equiparable. Dichos resultados apoyan la resección hepática en pacientes con enfermedad extrahepática estable. (AU)

Introduction: The presence of liver metastases in sarcomatous tumors is associated with poor prognosis. However, in selected patients, surgical resection has been suggested as a tool to improve survival rates. The aim of our study is to describe postoperative and oncological outcomes after liver resection. Methods: A retrospective unicentric study was conducted including patients diagnosed with hepatic metastases from soft tissue sarcoma who underwent hepatic resection between 2003 and 2019. The inclusion criteria were the presence of resectable disease, including synchronic and metachronic lesions. The presence of extra-hepatic controlled disease was not considered unresectable. Results: Nineteen patients underwent liver resection for liver metastasis of 7 different sarcomatous subtypes. Median age was 58-yo. Liver metastases were diagnosed a median 25 months after primary tumor diagnosis. Six patients (32%) suffered of synchronic metastases and 12 (63%) were affected of extrahepatic disease. Major hepatectomy was done in 5 (26%) patients, 8 (42%) minor complications were described. Median follow-up was 33 months. Survival analysis was performed independently for, GIST tumors and non-GIST sarcomas. One, three and five-year survival rate was 100%, 85.7% and 42.9% in non-GIST sarcomas, while five and ten-year survival rate was 100% and 40% in GIST, respectively. Conclusions: Surgical approach of liver metastases of sarcomatous tumors seems to be useful in order to improve survival in selected patients, while associated to be of low complications rate. In our cohort, extrahepatic disease rate is high in comparison with series published before, nevertheless survival is comparable. These results support performing surgical resection in selected patients with stable extrahepatic disease. (AU)

Pacientes críticos COVID-19. ¿Han variado el manejo y los resultados en la UCI tras un año de pandemia? Estudio multicéntrico, prospectivo, observacional / Critical patients COVID-19 has changed the management and outcomes in the ICU after 1 year of the pandemic? A multicenter, prospective, observational study

Objetivo: Comparar las características clínicas, los tratamientos y la evolución de los pacientes críticos con neumonía por COVID-19 atendidos en unidades de cuidados intensivos (UCI) tras un año de pandemia. Metodología: Estudio multicéntrico, prospectivo, en el que se incluyó pacientes críticos COVID-19 en 9 UCI del noroeste de España. Se compararon las características clínicas, los tratamientos y la evolución de pacientes ingresados en UCI durante los meses de marzo-abril de 2020 (periodo1) con pacientes ingresados en enero-febrero de 2021 (periodo2). Resultados: Se incluyeron 337 pacientes (98 en el periodo1 y 239 en el periodo2). En el periodo2 menos pacientes requirieron ventilación mecánica invasiva (VMI) (65% vs 84%, p<0,001), utilizándose con mayor frecuencia cánulas nasales de alto flujo (CNAF) (70% vs 7%, p<0,001), ventilación mecánica no invasiva (VMNI) (40% vs 14%, p<0,001), corticoides (100% vs 96%, p=0,007) y posición de decúbito prono tanto en pacientes despiertos (42% vs 28%, p=0,012) como en pacientes intubados (67% vs 54%, p=0,034). Los días de VMI, de estancia en UCI y hospitalaria fueron inferiores en el periodo2. La mortalidad fue similar en los dos periodos estudiados (16% vs 17%). Conclusiones: Tras un año de pandemia, observamos que en los pacientes ingresados en UCI se ha utilizado con mayor frecuencia CNAF, VMNI, uso del decúbito prono y corticoides, disminuyendo los pacientes en VMI, así como los tiempos de estancia en UCI y de estancia hospitalaria. La mortalidad ha sido similar en los dos periodos a estudio.(AU)

Objective: To compare the clinical characteristics, treatments, and evolution of critical patients with COVID-19 pneumonia treated in intensive care units (ICU) after one year of pandemic. Methodology: Multicenter, prospective study, which included critical COVID-19 patients in 9 ICUs in northwestern Spain. The clinical characteristics, treatments, and evolution of patients admitted to the ICU during the months of March-April 2020 (period1) were compared with patients admitted in January-February 2021 (period2). Results: 337 patients were included (98 in period1 and 239 in period2). In period2, fewer patients required invasive mechanical ventilation (IMV) (65% vs. 84%, P<.001), using high-flow nasal cannulas (CNAF) more frequently (70% vs. 7%, P<.001), ventilation non-invasive mechanical (NIMV) (40% vs. 14%, P<.001), corticosteroids (100% vs. 96%, P=.007) and prone position in both awake (42% vs. 28%, P=.012), and intubated patients (67% vs. 54%, P=.034). The days of IMV, ICU stay and hospital stay were lower in period2. Mortality was similar in the two periods studied (16% vs. 17%). Conclusions: After one year of pandemic, we observed that in patients admitted to the ICU, CNAF, NIMV, use of the prone position, and corticosteroids have been used more frequently, reducing the number of patients in IMV, and the length of stay in the ICU and hospital stay. Mortality was similar in the two study periods.(AU)

Mindfulness Prevents Depression and Psychopathology in Elderly People with Mild to Moderate Alzheimer's Disease: A Randomized Clinical Trial.

BACKGROUND: This longitudinal study addressed whether mindfulness practice prevents psychological and behavioral symptoms, especially mood disorders, in Alzheimer's disease (AD). OBJECTIVE: To assess the incidence of depression in the course of AD and to determine which non-pharmacological treatment (NPT) is most effective in preventing psychopathological symptoms. METHODS: We conducted a longitudinal, non-inferiority and equivalence randomized clinical trial, repeated-measures design, with a control group and three experimental treatments: mindfulness, cognitive stimulation, and relaxation. Each experimental group performed three weekly sessions for two years. The pharmacological treatment of all participants was donepezil (10 mg). Participants were patients with probable AD without diagnosed depression from the public neurology services of the Canary Health Service, Spain. Psychological evaluation was performed using the Geriatric Depression Scale (GDS), Hamilton Depression Rating Scale (HDRS), and Neuropsychiatric Inventory (NPI-Q). The statistical analysis included only patients who attended at least 75% of the sessions. A nonparametric, repeated-measures analysis was performed with Kruskal-Wallis H test and between-group differences with Mann-Whitney U test with Bonferroni correction (p < 0.008). Effect size was calculated with partial eta-squared. RESULTS: The results showed significant differences with large effect sizes (η2p>0.14) between mindfulness and the rest of the experimental groups as well as the control in the GDS, HDRS, and NPI-Q scales. CONCLUSION: Compared to the other experimental groups, only mindfulness prevented the onset of depression and other psychopathologies in early-stage AD. Based on its effectiveness in maintaining cognitive functions and preventing psychopathology, we recommend mindfulness as the first-choice NPT for mild to moderate AD.

In our cohort, extrahepatic disease rate is high in comparison with series published before, nevertheless survival is comparable. These results support performing surgical resection in selected patients with stable extrahepatic disease.

In period 2, fewer patients required invasive mechanical ventilation (IMV) (65% vs 84%, p < 0.001), using high-flow nasal cannulas (CNAF) more frequently (70% vs 7%, p < 0.001), ventilation non-invasive mechanical (NIMV) (40% vs 14%, p < 0.001), corticosteroids (100% vs 96%, p = 0.007) and prone position in both awake (42% vs 28%, p = 0.012), and intubated patients (67% vs 54%, p = 0.034). The days of IMV, ICU stay and hospital stay were lower in period 2. Mortality was similar in the two periods studied (16% vs 17%). CONCLUSIONS: After 1 year of pandemic, we observed that in patients admitted to the ICU, CNAF, NIMV, use of the prone position, and corticosteroids have been used more frequently, reducing the number of patients in IMV, and the length of stay in the ICU and hospital stay. Mortality was similar in the two study periods.
