Objectives The aim of this systematic review and meta-analysis is to the summarize the evidence on programmed cell death protein ligand 1 (PD-L1) in Epstein-Barr virus associated gastric cancer (EBVaGC) and to estimate the expression rate of PD-L1 among this subtype of Gastric Cancer (GC). Materials and methods For this study, PubMed®, EMBASE® and Web of Science® databases were searched for articles published until 1st November 2021. A total of 43 eligible publications with a total of 11,327 patients were included analysis based on inclusion and exclusion criteria. A total of 41 publications present data for proportion estimation and 33 for comparison of PD-L1 between EBV positive and negative GC. DerSimonian-Laird random-effects model was used for meta-analysis. Results The analysis showed that in EBVaGC the pooled positivity rate for PD-L1 was 54.6% (p < 0.001), with a high heterogeneity between the included studies, which was associated with variation on positivity criteria for PD-L1 expression. Overall, the study reveals an increased association between PD-L1 and EBVaGC (OR = 6.36, 95% CI 3.91–10.3, p < 0.001). Furthermore, the study revealed that GC with lymphoid stroma (GCLS) is highly associated with EBV (OR = 17.4, 95% CI 6.83–44.1, p < 0.001), with a pooled EBV positivity rate of 52.9% (p < 0.001). Conclusions Patients with EBVaGC tend to show higher PD-L1 expression, which enhances EBV positivity as a promising marker for patient selection for immunotherapy targeted agents. A uniform criteria for PD-L1 positivity in tumor cells is needed, as well as further prospective studies to validate our findings and their prognostic significance.

Literature reports that SARS-CoV-2 infection in cancer patients may be associated with higher severity and mortality, nevertheless the knowledge is limited. We aimed to describe patients’ demographic characteristics and COVID-19 disease outcomes in Portuguese cancer patients. We conducted a retrospective study in a cohort of cancer patients diagnosed with COVID-19. A total of 127 individuals were included: 46.5% males and 53.5% females, with a median age of 72 years. Clinicopathological characteristics were used in univariate and multivariable logistic regression analyses to estimate odds ratios for each variable with outcomes adjusting for potential confounders. Our cohort revealed that 84.3% of patients had more than one risk factor for severe disease rather than cancer. In total, 36.2% of patients were admitted to the Department of Internal Medicine, 14.2% developed severe disease, 1.6% required Intensive Care Unit, and mortality was observed in 11.8%. Severe COVID-19 disease was associated with unfit (ECOG PS > 2) patients (p = 0.009; OR = 6.39; 95% CI: 1.60–25.59), chronic kidney disease (p = 0.004; OR = 20.7; 95% CI: 2.64–162.8), immunosuppression (p < 0.001; OR = 10.3; 95% CI: 2.58–41.2), and presence of respiratory symptoms at diagnosis (p = 0.033; OR = 5.05; 95% CI: 1.14–22.4). Increased risk for mortality was associated with unfit patients (p = 0.036; OR = 4.22; 95% CI: 1.10–16.3), cardiac disease (p = 0.003; OR = 8.26; 95% CI: 2.03–33.6) and immunosuppression (p = 0.022; OR = 5.06; 95% CI: 1.27–20.18). Our results demonstrated that unfit and immunosuppressed patients, with chronic kidney disease and cardiac disease, have, respectively, an increased risk for severe disease and mortality related to COVID-19. Hence, this study provides important information on risk factors for severe COVID-19 disease and associated mortality in a Portuguese cancer population.

As lesões por pressão (LPP) representam importantes causas de morbimortalidade a nível mundial. Assim, objetivou-se identificar a ocorrência e características das LPP bem como, o perfil do paciente acometido. Trata-se de uma pesquisa descritiva, longitudinal e quantitativa, realizada em uma unidade de terapia intensiva adulto. A população foi constituída de registros de internações em prontuários no período de maio a dezembro de 2014 e a coleta de dados foi realizada em agosto de 2014 a janeiro de 2015. Identificou-se uma ocorrência de 22,07% com predomínio de lesões em mulheres idosas, com distúrbios respiratórios e presença de co-morbidades. Sete pacientes já apresentavam a lesão na admissão e 10 desenvolveram na UTI. A maioria das lesões estava no estágio II e na região sacral e, em relação ao desfecho clínico, 52,94% deles evoluiu para o óbito. O estudo evidenciou a importância da capacitação profissional como estratégia para reduzir a incidência dessas lesões.
