Relatório da OPAS mostra que as DCNTs continuam sendo a principal causa de morte e incapacidade nas Américas e alerta os países para que preparem os sistemas de saúde para uma população que envelhece rapidamente

Um novo relatório da Organização Pan-Americana da Saúde (OPAS) revela que, embora a expectativa de vida tenha aumentado nas Américas, também aumentou o número de pessoas que vivem com Doenças Crônicas Não Transmissíveis (DCNT).

A single-center, retrospective study-spring-evaluating the efficacy and safety of recombinant human vascular endothelial inhibitor combined with anti-PD-1 in elderly patients aged 80 and above with NSCLC.

Aim: To investigate the efficacy and safety of combining Recombinant Human Endostatin Injection (marketed as Endo) with anti-PD-1 in elderly patients aged 80 and above with non-small cell lung cancer (NSCLC). Methods: Retrospective analysis of 181 patients with NSCLC aged 80 and above treated in the Department of Respiratory and Critical Care Medicine at Chaohu Hospital, affiliated with Anhui Medical University, from June 2019 to January 2024. Patients who received at least one cycle of combined Endo with anti-PD-1 were included based on inclusion criteria. Clinical and pathological data were collected, including complete blood count, liver and kidney function, electrocardiogram, coagulation function, thyroid function, cardiac enzymes, and whole-body imaging. Adverse events were recorded with a final follow-up on January 25, 2024. The primary endpoints were progression-free survival (PFS) and overall survival (OS), with safety as a secondary endpoint. Results: This study involved 14 elderly patients with NSCLC aged over 80. Median progression-free survival (mPFS) was 102 days, and median overall survival (mOS) was 311 days. Subgroup analyses based on treatment cycles showed a non-significant 441-day mPFS increase in the long-term group (≥6 cycles, 5 patients) compared to the short-term group (<6 cycles, 9 patients). However, the mOS in the long-term group significantly exceeded the short-term group by 141 days, with statistical significance (P=0.048). Further categorization revealed a 204-day shorter mPFS in the monotherapy maintenance group (Endo or Immunol) compared to the combination maintenance group (Endo combined with Immunol, 441 days). The mOS of the monotherapy maintenance group was longer (686 days) than the combination maintenance group (311 days), but no statistical significance (P= 0.710, 0.920). Throughout the treatment, 77 adverse events were recorded, mainly grade 1-2, with no new treatment-related reactions occurred. Overall, the safety of Endo combined with anti-PD-1 was considered good and manageable. Conclusion: The combination of Endo and anti-PD-1 could be an effective treatment choice for patients with NSCLC aged 80 and above.

Development and validation of a prediction model for mortality in critically ill COVID-19 patients.

Background: Early prediction of prognosis may help early treatment measures to reduce mortality in critically ill coronavirus disease (COVID-19) patients. The study aimed to develop a mortality prediction model for critically ill COVID-19 patients. Methods: This retrospective study analyzed the clinical data of critically ill COVID-19 patients in an intensive care unit between April and June 2022. Propensity matching scores were used to reduce the effect of confounding factors. A predictive model was built using logistic regression analysis and visualized using a nomogram. Calibration and receiver operating characteristic (ROC) curves were used to estimate the accuracy and predictive value of the model. Decision curve analysis (DCA) was used to examine the value of the model for clinical interventions. Results: In total, 137 critically ill COVID-19 patients were enrolled; 84 survived, and 53 died. Univariate and multivariate logistic regression analyses revealed that aspartate aminotransferase (AST), creatinine, and myoglobin levels were independent prognostic factors. We constructed logistic regression prediction models using the seven least absolute shrinkage and selection operator regression-selected variables (hematocrit, red blood cell distribution width-standard deviation, procalcitonin, AST, creatinine, potassium, and myoglobin; Model 1) and three independent factor variables (Model 2). The calibration curves suggested that the actual predictions of the two models were similar to the ideal predictions. The ROC curve indicated that both models had good predictive power, and Model 1 had better predictive power than Model 2. The DCA results suggested that the model intervention was beneficial to patients and patients benefited more from Model 1 than from Model 2. Conclusion: The predictive model constructed using characteristic variables screened using LASSO regression can accurately predict the prognosis of critically ill COVID-19 patients. This model can assist clinicians in implementing early interventions. External validation by prospective large-sample studies is required.

Onset of Prolonged High-Potency Benzodiazepine Use Among ICU Survivors: A Nationwide Cohort Study.

OBJECTIVES: Exposure to critical illness and intensive care may lead to long-term psychologic and physical impairments. To what extent ICU survivors become prolonged users of benzodiazepines after exposure to critical care is not fully explored. This study aimed to describe the extent of onset of prolonged high-potency benzodiazepine use among ICU survivors not using these drugs before admission, identify factors associated with this use, and analyze whether such usage is associated with increased mortality. DESIGN: Retrospective cohort study. SETTING: Sweden, including all registered ICU admissions between 2010 and 2017. PATIENTS: ICU patients surviving for at least 3 months, not using high-potency benzodiazepine before admission, were eligible for inclusion. INTERVENTIONS: Admission to intensive care. MEASUREMENTS AND MAIN RESULTS: A total of 237,904 patients were screened and 137,647 were included. Of these 5338 (3.9%) became prolonged users of high-potency benzodiazepines after ICU discharge. A peak in high-potency benzodiazepine prescriptions was observed during the first 3 months, followed by sustained usage throughout the follow-up period of 18 months. Prolonged usage was associated with older age, female sex, and a history of both somatic and psychiatric comorbidities, including substance abuse. Additionally, a longer ICU stay, a high estimated mortality rate, and prior consumption of low-potency benzodiazepines were associated with prolonged use. The risk of death between 6 and 18 months post-ICU admission was significantly higher among high-potency benzodiazepine users, with an adjusted hazard ratio of 1.8 (95% CI, 1.7-2.0; p < 0.001). No differences were noted in causes of death between users and nonusers. CONCLUSIONS: Despite the lack of evidence supporting long-term treatment, prolonged usage of high-potency benzodiazepines 18 months following ICU care was notable and associated with an increased risk of death. Considering the substantial number of ICU admissions, prevention of benzodiazepine misuse may improve long-term outcomes following critical care.

Prognostic Significance of Thrombocytopenia and Mean Platelet Volume in COPD Patients with Acute Exacerbations in ICU Settings.

BACKGROUND Platelets have important modulatory effects on inflammatory and immune-mediated pathways. Thrombocytopenia is a critical condition that is frequently encountered in the intensive care unit (ICU) and increases mortality. This retrospective study of 472 patients admitted to the ICU with acute exacerbation of chronic obstructive pulmonary disease (COPD) aimed to evaluate thrombocytopenia and mean platelet volume (MPV) with prognosis and patient mortality. MATERIAL AND METHODS A total of 472 patients diagnosed with COPD according to GOLD criteria and hospitalized in the tertiary ICU between 1 April 2018 and 11 May 2021 were included in the study. Platelets were calculated by the impetance method and MPV was simultaneously calculated based on the platelet histogram. Patients with platelet count ≤100×109/L and >100×109/L and patients with MPV values <7 fl, 7-11 fl, and >11fl were compared in terms of mortality and prognosis. RESULTS The mortality rate in COPD patients with thrombocytopenia was high, at 61.5%. Thrombocytopenia (P=.002), high MPV (P=.006) Acute Physiology and Chronic Health Evaluation-2 (APACHE-II) score (P=.025), length of stay (LOS) in the ICU (P=.009), mechanical ventilation duration (P<.001), leukocytosis (P<.001), high Sequential Organ Failure Assessment (SOFA) score (P<.001), LOS in the hospital (P=.035), and hypoalbuminemia (P<.001) were significantly associated with mortality. CONCLUSIONS Thrombocytopenia, high MPV, high APACHE-II and SOFA scores, LOS in the ICU and hospital, duration of mechanical ventilation, leukocytosis, and hypoalbuminemia predict mortality in COPD patients. Since infection-sepsis, hypoalbuminemia, and hypoxia can worsen this situation, ensuring early infection control, providing albumin support, and preventing hypoxia contribute significantly to reducing thrombocytopenia and mortality.

Pediatric Cardiac Critical Care: A Vital Link in the Chain-of-Survival of Children with Congenital Heart Disease.

Despite significant strides made in childhood survival during the last 75 years, India bears the largest burden of congenital heart disease (CHD) in the world. The care of a child with CHD requires multidisciplinary collaboration and development of distinct training opportunities in developing countries to ensure outcomes similar to those achieved in high-income countries. We present a commentary on the current state of pediatric cardiac critical care in India and propose pathways to fulfil the unmet needs of Indian children. The aim is to achieve self-reliance in pediatric cardiac services and to move towards optimal outcome and intact survival of children with CHD.

The inflammatory markers combined with CA125 may predict postoperative survival in endometrial cancer.

BACKGROUND: Endometrial cancer (EC) has a high latency, making prognosis difficult to predict. Cancer antigen 125 (CA125) is not specific as a tumour marker for EC; however, complete blood count (CBC) inflammatory markers are associated with prognosis in various malignancies. Thus, this study investigated the value of CBC inflammatory markers combined with CA125 levels in predicting the prognosis of patients with EC. METHODS: In this study, 517 patients with EC were recruited between January 2015 and January 2022, and clinical characteristics, CBC inflammatory markers, and CA125 levels were assessed. Differences in each index at different EC stages and the correlation between the index and EC stage were analysed, and the influence of the index on EC prognosis was evaluated. RESULTS: Platelet distribution width (PDW) levels were significantly lower in patients with advanced EC than in those with early EC, whereas the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and CA125 levels were significantly higher in patients with advanced EC (all P < 0.05). ROC curve and multivariate logistic regression analyses indicated that decreased PDW and increased CA125 levels were independent risk factors for EC staging progression. In addition, multivariate Cox regression analysis showed that the combination of low PDW and high CA125 (PDW + CA125 = 2) was an independent prognostic factor of survival in EC patients. Kaplan-Meier survival analysis indicated that patients with low PDW and high CA125 had worse overall survival. CONCLUSIONS: The PDW and CA125 score may be an independent prognostic factor for postoperative overall survival in patients with EC and a useful marker for predicting the prognosis of these patients.

Endometrial cancer (EC) has a high latency period, and the prognosis of EC is difficult to predict. The inflammatory response within the tumour microenvironment plays an important role in the occurrence and development of cancer. In our study, various inflammatory indicators in complete blood counts were comprehensively analysed, and cancer antigen 125 (CA125) was further used to predict the stage and prognosis of EC. The results showed that patients with low platelet distribution width (PDW) and high CA125 levels had poorer overall survival. The PDW and CA125 score may be used as a new independent prognostic indicator.

Assessment of Posttransplant Bacteremia Caused by Extended-Spectrum Beta-Lactamase-Producing Gram-Negative Bacteria Among Kidney Transplant Recipients.

BACKGROUND: Extended-spectrum beta-lactamase-producing gram-negative rods (ESBL-GNR) are a rising cause of bacteremia in kidney transplant recipients (KT). The study purpose was to examine patient mortality, allograft survival, estimated glomerular filtration rate (eGFR) at the end of 1 year, and readmission rates while looking at treatment strategies among KTs with ESBL-GNR and non-ESBL-GNR bacteremia at our institution. METHODS: This study was a retrospective, cohort analysis of KTs with gram-negative bacteremia from January 1, 2020, to December 31, 2021. The primary outcome of the study was mortality. Patient outcomes were assessed for 365 days after positive blood cultures. RESULTS: The study included 63 patients. Of these, 18 (29%) patients had bacteremia caused by an ESBL-GNR and 45 (71%) patients had bacteremia caused by a non-ESBL-GNR. Patient survival at 90 days was 94% in the ESBL-GNR group and 96% in the non-ESBL-GNR group. Ciprofloxacin was the most common antimicrobial therapy at discharge (68.9%) in the non-ESBL-GNR group whereas ertapenem was the most common in the ESBL-GNR group (44.5%). Median eGFR at discharge was 41 mL/min/1.73 m2 in the ESBL-GNR group and 48 mL/min/1.73 m2 in the non-ESBL-GNR group. Ninety-day readmission occurred in 9 (50%) ESBL-GNR patients and 14 (32%) non-ESBL-GNR patients. None of the above comparisons are statistically significant (p > 0.05). Eleven (61%) ESBL-GNR and 2 (4%) non-ESBL-GNR patients used outpatient parenteral antimicrobial therapy (p < 0.001). CONCLUSIONS: Among KTs with ESBL-GNR bacteremia, no significant difference was detected in mortality or allograft function compared to non-ESBL-GNR bacteremia.

A retrospective study of prognostic factors and treatment outcome in advanced-stage Mycosis Fungoides and Sezary Syndrome.

Background: Mycosis fungoides (MF) and Sezary Syndrome (SS) comprise over half of all Cutaneous T-cell lymphoma diagnoses. Current risk stratification is largely based on TNMB staging, few research investigated the prognostic value of clinical exams. Current systemic therapy for advanced disease includes immunomodulatory drugs, chemotherapy, and HADC inhibitors. Few clinical trials or retrospective research compared the efficacy of different drugs.Method: Here, we performed a retrospective analysis of prognostic factors and treatment outcomes of 92 patients diagnosed with MF/SS at the Peking Union Medical College Hospital from 2013-2023.Results: Cox regression analysis identified that age ≥ 50 years, WBC ≥ 8 × 109/L, serum LDH ≥ 250U/L, ß2-MG ≥ 4.50 mg/L, and stage IV were associated with reduced overall survival, age ≥ 50 years, serum LDH ≥ 250U/L and stage IV were associated with reduced progression free survival. Kaplan-Meier analysis established that immunomodulatory therapy was associated with longer progression free survival.Conclusion: These results suggested new factors in predicting prognosis and selecting appropriate treatments in patients with advanced MF/SS.

ProtecT-2-D trial protocol: cardiovascular protection in patients with type 2 diabetes and established heart and/or vascular disease at a cardio-metabolic clinic-a randomized controlled trial.

BACKGROUND: Cardiovascular disease remains the primary cause of morbidity and mortality despite advancements in the treatment of patients with type 2 diabetes. Effective diabetes management extends beyond blood glucose control and includes cardiovascular prevention and treatment. However, the conventional healthcare model often emphasizes single-disease-specific management, leading to fragmented care. We aim to establish an affordable Cardio-Metabolic Clinic (CMC) that can provide comprehensive assessment and specialized care with a focus on cardiovascular protection. METHODS: The ProtecT-2-D study is a prospective, randomized control trial at the Cardiovascular Research Unit, Odense University Hospital Svendborg, Denmark. In this study, 1500 participants with type 2 diabetes and cardiovascular disease will be randomly assigned in a 2:1 ratio to receive either the intervention: treatment in the CMC, or the control: standard of care. The Cardio-Metabolic Clinic applies a decision-making algorithm coded with the latest guidelines to evaluate lifestyle factors and manage medical treatment. Health examinations are conducted at baseline and after three years, and clinical events will be assessed through registry and journal audits after five and ten years. The primary outcome is the time to the first occurrence of a composite of cardiovascular deaths, non-fatal acute myocardial infarctions, non-fatal stroke, or hospitalization due to heart failure at a time frame of five years. DISCUSSION: The Cardio-Metabolic Clinic represents a pioneering approach to diabetes management that aims to improve patient outcomes by reducing the cardiovascular disease burden. This study could transform diabetes care and offer a multidisciplinary, cost-effective, and specialized treatment. We need to establish the efficacy and feasibility of a CMC to integrate comparable clinics into broader healthcare systems, and potentially enhance cardiovascular health in patients with type 2 diabetes.

Guanylate binding protein 5 is an immune-related biomarker of oral squamous cell carcinoma: A retrospective prognostic study with bioinformatic analysis.

BACKGROUND: Cancer utilizes immunosuppressive mechanisms to create a tumor microenvironment favorable for its progression. The purpose of this study is to histologically characterize the immunological properties of the tumor microenvironment of oral squamous cell carcinoma (OSCC) and identify key molecules involved in the immunological microenvironment and patient prognosis. METHODS: First, overlapping differentially expressed genes (DEGs) were screened from OSCC transcriptome data in public databases. Correlation analysis of DEGs with known immune-related genes identified genes involved in the immune microenvironment of OSCC. Next, stromal patterns of tumor were classified and immunohistochemical staining was performed for immune cell markers (CD3, CD4, Foxp3, CD8, CD20, CD68, and CD163), programmed death-ligand 1 (PD-L1), and guanylate binding protein 5 (GBP5) in resected specimens obtained from 110 patients with OSCC who underwent resection. Correlations between each factor and their prognostic impact were analyzed. RESULTS: Among the novel OSCC-specific immune-related genes screened (including ADAMDEC1, CXCL9, CXCL13, DPT, GBP5, IDO1, and PLA2G7), GBP5 was selected as the target gene. Histopathologic analysis showed that multiple T-cell subsets and CD20-positive cells were less common in the advanced stages, whereas CD163-positive cells were more common in advanced stages. The immature type in the stromal pattern category was associated with less immune cell infiltration, lower expression of PD-L1 in immune cells, lower expression of GBP5 in the stroma, and shorter overall survival and recurrence-free survival. Expression of GBP5 in the tumor and stroma correlated with immune cell infiltration of tumors and PD-L1 expression in tumor and immune cells. Patients with low tumor GBP5 expression and high stromal expression had significantly longer overall survival and recurrence-free survival. CONCLUSIONS: The stromal pattern category may reflect both invasive and immunomodulatory potentials of cancer-associated fibroblasts in OSCC. GBP5 has been suggested as a potential biomarker to predict the prognosis and therapeutic efficacy of immune checkpoint inhibitors.

Organ Involvement Related to Death in Critically Ill Patients With Leptospirosis: Unsupervised Analysis in a French West Indies ICU.

OBJECTIVES: To identify distinct phenotypes of critically ill leptospirosis patients upon ICU admission and their potential associations with outcome. DESIGN: Retrospective observational study including all patients with biologically confirmed leptospirosis admitted to the ICU between January 2014 and December 2022. Subgroups of patients with similar clinical profiles were identified by unsupervised clustering (factor analysis for mixed data and hierarchical clustering on principal components). SETTING: All patients admitted to the ICU of the University Hospital of Guadeloupe on the study period. PATIENTS: One hundred thirty critically ill patients with confirmed leptospirosis were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: At ICU admission, 34% of the patients had acute respiratory failure, and 26% required invasive mechanical ventilation. Shock was observed in 52% of patients, myocarditis in 41%, and neurological involvement in 20%. Unsupervised clustering identified three clusters-"Weil's Disease" (48%), "neurological leptospirosis" (20%), and "multiple organ failure" (32%)-with different ICU courses and outcomes. Myocarditis and neurological involvement were key components for cluster identification and were significantly associated with death in ICU. Other factors associated with mortality included shock, acute respiratory failure, and requiring renal replacement therapy. CONCLUSIONS AND RELEVANCE: Unsupervised analysis of critically ill patients with leptospirosis revealed three patient clusters with distinct phenotypic characteristics and clinical outcomes. These patients should be carefully screened for neurological involvement and myocarditis at ICU admission.

ctGAN: combined transformation of gene expression and survival data with generative adversarial network.

Recent studies have extensively used deep learning algorithms to analyze gene expression to predict disease diagnosis, treatment effectiveness, and survival outcomes. Survival analysis studies on diseases with high mortality rates, such as cancer, are indispensable. However, deep learning models are plagued by overfitting owing to the limited sample size relative to the large number of genes. Consequently, the latest style-transfer deep generative models have been implemented to generate gene expression data. However, these models are limited in their applicability for clinical purposes because they generate only transcriptomic data. Therefore, this study proposes ctGAN, which enables the combined transformation of gene expression and survival data using a generative adversarial network (GAN). ctGAN improves survival analysis by augmenting data through style transformations between breast cancer and 11 other cancer types. We evaluated the concordance index (C-index) enhancements compared with previous models to demonstrate its superiority. Performance improvements were observed in nine of the 11 cancer types. Moreover, ctGAN outperformed previous models in seven out of the 11 cancer types, with colon adenocarcinoma (COAD) exhibiting the most significant improvement (median C-index increase of ~15.70%). Furthermore, integrating the generated COAD enhanced the log-rank p-value (0.041) compared with using only the real COAD (p-value = 0.797). Based on the data distribution, we demonstrated that the model generated highly plausible data. In clustering evaluation, ctGAN exhibited the highest performance in most cases (89.62%). These findings suggest that ctGAN can be meaningfully utilized to predict disease progression and select personalized treatments in the medical field.

Infective endocarditis and spondylodiscitis-impact of sequence of surgical therapy on survival and recurrence rate.

OBJECTIVES: To date, there are no standardized treatment algorithms or recommendations for patients with infective endocarditis (IE) and concomitant spondylodiscitis (SD). Therefore, our aim was to analyse whether the sequence of surgical treatment of IE and SD has an impact on postoperative outcome and to identify risk factors for survival and postoperative recurrence. METHODS: Patients with IE underwent surgery in 4 German university hospitals between 1994 and 2022. Univariable and multivariable analyses were performed to identify possible predictors of 30-day/1-year mortality and recurrence of IE and/or SD. RESULTS: From the total IE cohort (n = 3991), 150 patients (4.4%) had concomitant SD. Primary surgery for IE was performed in 76.6%, and primary surgery for SD in 23.3%. The median age was 70.0 (64.0-75.6) years and patients were mostly male (79.5%). The most common pathogens detected were enterococci and Staphylococcus aureus followed by streptococci, and coagulase-negative Staphylococci. If SD was operated on first, 30-day mortality was significantly higher than if IE was operated on 1st (25.7% vs 11.4%; P = 0.037) and we observed a tendency for a higher 1-year mortality. If IE was treated 1st, we observed a higher recurrence rate within 1 year (12.2% vs 0%; P = 0.023). Multivariable analysis showed that primary surgery for SD was an independent predictor of 30-day mortality. CONCLUSIONS: Primary surgical treatment for SD was an independent risk factor for 30-day mortality. When IE was treated surgically 1st, the recurrence rate of IE and/or SD was higher.

Multilevel analysis of healthcare utilization for childhood diarrhea in high under five mortality countries.

Globally, 4.9 million under-five deaths occurred before celebrating their fifth birthday. Four in five under-five deaths were recorded in sub-Saharan Africa and Southern Asia. Childhood diarrhea is one of the leading causes of death and is accountable for killing around 443,832 children every year. Despite healthcare utilization for childhood diarrhea has a significant effect on the reduction of childhood mortality and morbidity, most children die due to delays in seeking healthcare. Therefore, this study aimed to assess healthcare utilization for childhood diarrhea in the top high under-five mortality countries. This study used secondary data from 2013/14 to 2019 demographic and health surveys of 4 top high under-five mortality countries. A total weighted sample of 7254 mothers of under-five children was included. A multilevel binary logistic regression was employed to identify the associated factors of healthcare utilization for childhood diarrhea. The statistical significance was declared at a p-value less than 0.05 with a 95% confidence interval. The overall magnitude of healthcare utilization for childhood diarrhea in the top high under-five mortality countries was 58.40% (95% CI 57.26%, 59.53%). Partner/husband educational status, household wealth index, media exposure, information about oral rehydration, and place of delivery were the positive while the number of living children were the negative predictors of healthcare utilization for childhood diarrhea in top high under-five mortality countries. Besides, living in different countries compared to Guinea was also an associated factor for healthcare utilization for childhood diarrhea. More than four in ten children didn't receive health care for childhood diarrhea in top high under-five mortality countries. Thus, to increase healthcare utilization for childhood diarrhea, health managers and policymakers should develop strategies to improve the household wealth status for those with poor household wealth index. The decision-makers and program planners should also work on media exposure and increase access to education. Further research including the perceived severity of illness and ORS knowledge-related factors of healthcare utilization for childhood diarrhea should also be considered by other researchers.

Prognostic relevance of prognostic nutritional indices in gastric or gastro-esophageal junction cancer patients receiving immune checkpoint inhibitors: a systematic review and meta-analysis.

Background: The Prognostic Nutritional Index (PNI) has become an important predictive tool for assessing patients' nutritional status and immune competence. It is widely used in prognostic evaluations for various cancer patients. However, the prognostic relevance of the Prognostic Nutritional Index (PNI) in gastric or gastro-esophageal junction cancer patients (GC/GEJC) undergoing immune checkpoint inhibitors (ICIs) treatment remains unclear. This meta-analysis aimed to determine the prognostic impact of PNI in this specific patient cohort. Methods: We conducted a thorough literature search, covering prominent databases such as PubMed, Embase, Web of Science, SpringerLink, and the Cochrane Library. The search spanned from the inception of these databases up to December 5, 2023. Employing the 95% confidence interval and Hazard Ratio (HR), the study systematically evaluated the relationship between PNI and key prognostic indicators, including the objective remission rate (ORR), disease control rate (DCR), overall survival (OS) and progression-free survival (PFS) in GC/GEJC patients undergoing ICI treatment. Results: Eight studies comprising 813 eligible patients were selected. With 7 studies consistently demonstrating superior Overall Survival (OS) in the high-Prognostic Nutritional Index (PNI) group compared to their low-PNI counterparts (HR 0.58, 95% CI: 0.47-0.71, P<0.001). Furthermore, the results derived from 6 studies pointed out that the significant correlation between he low-PNI and poorer progression-free survival (PFS) (HR 0.58, 95% CI: 0.47-0.71, P<0.001). Subgroup analyses were performed to validate the robustness of the results. In addition, we conducted a meta-analysis of three studies examining the correlation between PNI and objective response rate/disease control rate (ORR/DCR) and found that the ORR/DCR was significantly superior in the high PNI group (ORR: RR: 1.24, P=0.002; DCR: RR: 1.43, P=0.008). Conclusion: This meta-analysis indicates that the low-PNI in GC/GEJC patients undergoing ICI treatment is significantly linked to worse OS and PFS. Therefore, PNI can serve as a prognostic indicator of post-treatment outcomes in patients with GC receiving ICIs. Further prospective studies are required to assess the reliability of these findings.

The role of surgery for invasive pulmonary aspergillosis in paediatric hemato-oncology patients-Can we better define it?

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a serious condition with high morbidity and mortality in paediatric patients with cancer, haematological diseases or immunodeficiencies with or without allogeneic haematopoietic stem cell transplantation (HSCT). The role of surgical intervention for the management of IPA has scarcely been investigated. OBJECTIVES: The aim of this study was to present a single center experience of management of IPA in paediatric patients of an oncological ward, to determine the short and long-term outcomes after thoracic surgical interventions, and to outline the indications of surgical interventions in selected patients. PATIENTS/METHODS: We conducted a retrospective study of 44 paediatric patients with proven and probable IPA treated in our institution between January 2003 and December 2021. The primary endpoint was the overall survival after surgical interventions. Secondary endpoints included post-operative morbidity and mortality. RESULTS: The median age at diagnosis of IPA in our cohort was 11.79 years (range 0.11-19.6). The underlying conditions were malignancies in 34 (77%) patients and haematological or immunological disorders with allogeneic HSCT in 9 (23%) patients. We performed thoracic surgical interventions in 10 (22.7%) patients. Most patients received a video assisted thoracic surgery. Only one patient died within 90 days after surgery with a median follow-up time of 50 months. No other major post-operative complications occurred. The calculated 5-year survival rate from IPA for patients after surgical intervention with curative intention was 57% and 56% for patients without (p = .8216). CONCLUSIONS: IPA resulted in relevant morbidity and mortality in our paediatric patient cohort. Thoracic surgical interventions are feasible and may be associated with prolonged survival as a part of multidisciplinary approach in selected paediatric patients with IPA. Larger scale studies are necessary to investigate the variables associated with the necessity of surgery.

Evaluating the Effects of Time From Brain Death and Type of Inotrope Usage on Result of Heart Transplant: Results of 1-Year Follow-Up.

OBJECTIVES: Heart transplant is the most effective treatment in patients with advanced heart failure who are refractory to medical treatment. The brain death interval and type of inotrope We assessed the effects of these parameters on heart transplant outcomes. MATERIALS AND METHODS: In this follow-up study, we followed heart transplant recipients for 1 year to study patient survival, ejection fraction, adverse events, and organ rejection. We evaluated follow-up results on time from brainstem death test to the cross-clamp placement, as well as the type of inotrope used. RESULTS: Our study enrolled 54 heart transplant candidates. The inotrope dose was 3.66 ± 0.99 µg/kg/min, and the most used inotrope, with 28 cases (51.9%), was related to dopamine. Six cases (11.1%) of death and 1 case of infection after transplant were observed in recipients. The average ejection fraction of transplanted hearts before transplant, instantly at time of transplant, and 1 month, 6 months, and 1 year after transplant was 54.9 ± 0.68, 52.9 ± 10.4, 51.9 ± 10.7, 50.1 ± 10.9, and 46.8 ± 17, respectively; this decreasing trend over time was significant (P =.001). Furthermore, ejection fraction changes following transplant did not differ significantly in transplanted hearts regarding brain death interval and type of inotrope used. CONCLUSIONS: Our study revealed that cardiac output of a transplanted heart may decrease over time and the time elapsed from brain death, and both dopamine and norepinephrine could have negligible effects on cardiac function.

Factors Associated With Recurrence of Underlying Diseases Among Liver Transplant Recipients: A Single-Center Study.

OBJECTIVES: The recurrence of underlying diseases remains a major cause of graft failure after liver transplant. This study aimed to identify factors associated with the recurrence of underlying diseases and investigate the incidence of these factors and recurrence at the main liver transplant center in Iran. MATERIALS AND METHODS: We included adult liver transplant recipients followed at Shiraz Transplant Center between 2011 and 2018 with a confirmed diagnosis of recurrence of underlying disease in our study. We reviewed medical records and extracted data on demographic characteristics, clinical and paraclinical features, medication use, and current status. We used a systematic random sampling method to select a control group of 95 transplant recipients who did not have recurrence. Of 3022 total transplant recipients, 76 recipients experienced a recurrence of their underlying disease. RESULTS: Model for End-Stage Liver Disease score, underlying disease, recipient blood group, donor sex, donor blood group, and rejection frequency were significantly different between study groups with and without recurrence of underlying diseases. Liver transplant recipients with recurrence had lower mean Model for End-Stage Liver Disease score. Recipients with recurrence also had higher rate of drug consumption (eg, prednisolone, tacrolimus, mycophenolate mofetil, sirolimus). Regression analysis showed that donor sex and rejection frequency had an effect on disease recurrence. Death occurred more frequently in liver transplant recipients with recurrence than in the control group (39.5% vs 26.3%), butthe difference was not significant. CONCLUSIONS: Donor sex and acute rejection frequency are independent factors predictive of the recurrence of underlying disease. Modifying risk factors can help minimize the recurrence of underlying diseases after liver transplant.

Actual Cost of Extracorporeal Cardiopulmonary Resuscitation: A Time-Driven Activity-Based Costing Study.

OBJECTIVES: To determine the actual cost and drivers of the cost of an extracorporeal cardiopulmonary resuscitation (E-CPR) care cycle. PERSPECTIVE: A time-driven activity-based costing study conducted from a healthcare provider perspective. SETTING: A quaternary care ICU providing around-the-clock E-CPR service for out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) in Australia. METHODS: The E-CPR care cycle was defined as the time from initiating E-CPR to hospital discharge or death of the patient. Detailed process maps with discrete steps and probabilistic decision nodes accounting for the complex trajectories of E-CPR patients were developed. Data about clinical and nonclinical resources and timing of activities was collected multiple times for each process . Total direct costs were calculated using the time estimates and unit costs per resource for all clinical and nonclinical resources. The total direct costs were combined with indirect costs to obtain the total cost of E-CPR. RESULTS: From 10 E-CPR care cycles observed during the study period, a minimum of 3 observations were obtained per process. The E-CPR care cycle's mean (95% CI) cost was $75,014 ($66,209-83,222). Initiation of extracorporeal membrane oxygenation (ECMO) and ECMO management constituted 18% of costs. The ICU management (35%) and surgical costs (20%) were the primary cost determinants. IHCA had a higher mean (95% CI) cost than OHCA ($87,940 [75,372-100,570] vs. 62,595 [53,994-71,890], p < 0.01), mainly because of the increased survival and ICU length of stay of patients with IHCA. The mean cost for each E-CPR survivor was $129,503 ($112,422-147,224). CONCLUSIONS: Significant costs are associated with E-CPR for refractory cardiac arrest. The cost of E-CPR for IHCA was higher compared with the cost of E-CPR for OHCA. The major determinants of the E-CPR costs were ICU and surgical costs. These data can inform the cost-effectiveness analysis of E-CPR in the future.
