Factors Associated With Long Survival in Patients With Cancer Admitted to Palliative Care: An Exploratory Study.

Objective: Some patients with cancer admitted to palliative care have relatively long survivals of 1 year or more. The objective of this study was to find out factors associated with prolonged survival. Methods: Retrospective case-control study comparing the available data of patients with cancer who survived more than 1 year after admission in a palliative care service with patients with cancer who survived 6 months or less. The intended proportion was 4 controls for each case. Patients were identified through electronic records from 2012 until 2018. Results: And 1721 patients were identified. Of those patients, 111 (6.4%) survived for at least 1 year, and 363 (21.1%) were included as controls according to the established criteria. The intended proportion could not be reached; the proportion was only 3.3:1. The median survival of cases was 581 days (range: 371-2763), and the median survival of controls was 57 days (range: 1-182). In the multivariable analysis, patients with a hemoglobin ≥ 10.6 g/dL and a creatinine level >95 µmol/L had a higher probability of living more than 1 year. In contrast, patients with abnormal cognition, pain, anorexia, liver metastases, an Eastern Cooperative Oncology Group performance status >1, and a neutrophil/lymphocyte ratio ≥ 3.43 had a low probability of living more than 1 year. Conclusion: Several factors were statistically associated positively or negatively with prolonged survival. However, the data of this study should be confirmed in other studies.

Symptoms of anxiety and depression in patients with persistent asthma: a cross-sectional analysis of the INSPIRERS studies.

OBJECTIVES: Anxiety and depression are relevant comorbidities in asthma, but, in Portugal and Spain, data on this topic are scarce. We assessed, in patients with asthma, the frequency of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) and the European Quality of Life Five Dimension Questionnaire (EQ-5D); the level of agreement between these questionnaires, and the factors associated with these symptoms. METHODS: This is a secondary analysis of the INSPIRERS studies. A total of 614 adolescents and adults with persistent asthma (32.6±16.9 years, 64.7% female) were recruited from 30 primary care centres and 32 allergy, pulmonology and paediatric clinics. Demographic and clinical characteristics, HADS and EQ-5D were collected. A score ≥8 on Hospital Anxiety and Depression Scale-Anxiety/Hospital Anxiety and Depression Scale-Depression or a positive answer to EQ-5D item 5 indicated the presence of these symptoms. Agreement was determined by Cohen's kappa. Two multivariable logistic regressions were built. RESULTS: According to HADS, 36% of the participants had symptoms of anxiety and 12% of depression. According to EQ-5D, 36% of the participants had anxiety/depression. The agreement between questionnaires in identifying anxiety/depression was moderate (k=0.55, 95% CI 0.48 to 0.62). Late asthma diagnosis, comorbidities and female gender were predictors of anxiety/depression, while better asthma control, health-related quality of life and perception of health were associated with lower odds for anxiety/depression. CONCLUSION: At least 1/3 of the patients with persistent asthma experience symptoms of anxiety/depression, showing the relevance of screening these disorders in patients with asthma. EQ-5D and HADS questionnaires showed a moderate agreement in the identification of anxiety/depression symptoms. The identified associated factors need to be further investigated in long-term studies.

Immune checkpoint inhibitor (ICI)-based treatment beyond progression with prior immunotherapy in patients with stage IV non-small cell lung cancer: a retrospective study.

Background: Although immune checkpoint inhibitors (ICIs) provide unprecedented survival improvement for patients with advanced non-small cell lung cancer (NSCLC), disease progression inevitably occurs. After ICIs failure, limited data exist on whether ICI-based treatment beyond progression (TBP) may be beneficial to advanced NSCLC. This retrospective study aimed to evaluate the efficacy of this treatment approach in advanced NSCLC and identify potential beneficial factors. Methods: Patients with stage IV NSCLC who received ICI-based treatment after the failure of prior PD-1/PD-L1 inhibitor treatments (monotherapy or combination therapy) between January 2016 and July 2020 were enrolled. Their clinical characteristics and treatment procedures were collected, and the follow-up would be performed. Results: A total of 204 patients were included. All patients had disease progression after prior immunotherapy, with 49.5% (101/204) of patients presenting with new metastasis lesions and the rest 50.5% (103/204) of patients' progression on originate lesions. Within the entire cohort, the median progression-free survival (PFS) and median overall survival (OS) of ICI-based TBP with prior immunotherapy were 5.0 months (95% CI: 4.5-5.5 months) and 15.7 months (95% CI: 14.7-16.8 months), respectively. The objective response rate (ORR) and disease control rate (DCR) were 9.3% and 74.0%, respectively. According to the multivariate analysis, ICI-based combination therapy [PFS: hazard ratio (HR), 0.48, 95% confidence interval (CI): 0.28-0.84, P=0.011] (OS: HR, 0.44, 95% CI: 0.23-0.85, P=0.014), not having targetable gene alterations (PFS: HR, 0.56, 95% CI: 0.40-0.79, P=0.001) (OS: HR, 0.57, 95% CI: 0.37-0.87, P=0.009), and good response to prior immunotherapy (PFS: HR, 0.36, 95% CI: 0.24-0.53, P<0.0001) (OS: HR, 0.31, 95% CI: 0.19-0.52, P<0.0001) were independently associated with improved PFS and OS. Moreover, disease progression due to appearances of new metastasis (OS: HR, 0.56, 95% CI: 0.37-0.84, P=0.005) was only associated with better OS. Conclusions: While the ORR in patients with advanced NSCLC receiving ICI-based TBP with prior immunotherapy was limited, the DCR was relatively high in our study which is encouraging. ICI-based treatment strategy may be a reasonable option for patients who progressed from prior immunotherapy. Further prospective studies on larger sample size are warranted.

Raoultella ornithinolytica in MALT-type non-Hodgkin Lymphoma.

Raoultella ornithinolytica is a bacterium that belongs to the Enterobacteriaceae family. The most frequently reported infections are gastrointestinal and hepatobiliary. Urinary tract infections are very rarely reported and bloodstream infections are usually reported without an identified source. This bacterium is responsible for an increasing number of infections, especially in immunocompromised patients. The authors describe the first case ever reported of an immunocompromised patient due to non-Hodgkin lymphoma MALT type and corticotherapy, who developed urinary tract infection and subsequently bacteriemia due to this pathogen. LEARNING POINTS: Raoultella ornithinolytica is a virulent pathogen causing community-acquired and hospital-acquired infection, especially in immunocompromised populations.Although most cases of R. ornithinolytica infection are susceptible to standard antibiotic regimens, multi-drug resistant strains have been reported, which may pose a severe risk to the immunocompromised patient.Physicians should be aware that some treatments may increase immunosuppression, thus enabling infection by opportunistic agents such as R. ornithinolytica.

Transition from APAP to CPAP may be a cost-effective health intervention in OSA patients.

OBJECTIVE: Obstructive sleep apnea (OSA) is a common disorder associated with a significant economic burden. Continuous positive airway pressure (CPAP) and auto-titrating positive airway pressure (APAP) are recognized therapeutic options in patients with OSA, although treatment costs are higher with APAP. We conducted a study aimed at evaluating the effectiveness and potential cost savings resulting from the implementation of a protocol guiding the transition to CPAP in OSA patients previously treated with APAP. METHODS: This prospective study included patients with OSA under APAP who were followed up at the Sleep Medicine outpatient clinic of a tertiary referral hospital between January 2019 and January 2021. Treatment was switched to CPAP in patients who met the following criteria: satisfactory adaptation and adherence to APAP, residual apnea-hypopnea index (AHI) of < 5/hour, and no relevant air leaks. APAP and CPAP outcomes were compared and an estimate of the savings obtained by the transition from APAP to CPAP was calculated. RESULTS: Ninety-three patients were included in the study. APAP and CPAP were both effective in correcting obstructive events and improving daytime sleepiness. No significant differences were found regarding treatment adherence and tolerance between both PAP modalities. The selection of fixed-pressure CPAP through 90th or 95th percentile APAP pressure proved to be effective and an alternative strategy to titration polysomnography. At the end of this two-year study, the transition from APAP to CPAP enabled savings of at least 10,353€. CONCLUSION: The transition from APAP to CPAP may be an effective, well-tolerated, safe, and cost-saving strategy in patients with OSA.

Peripheral blood eosinophilia may be a prognostic biomarker in non-small cell lung cancer patients treated with immunotherapy.

BACKGROUND: Eosinophils have been traditionally associated with the initiation and propagation of inflammatory responses, particularly in allergic diseases and helminth infections. More recently, an association between eosinophils and cancer has been the focus of several studies, but controversial results have emerged. This study aims to evaluate the prognostic role of peripheral blood eosinophilia in non-small cell lung cancer (NSCLC) patients receiving immunotherapy (IO). We also evaluated the impact of peripheral eosinophilia on the occurrence of immune-related adverse effects (irAEs). METHODS: Advanced NSCLC patients under IO were included in a retrospective single-center study. Peripheral blood eosinophilia was defined by a count greater than 500/µL. Patients were analyzed for eosinophil counts, overall survival (OS), progression-free survival (PFS), overall response rate (ORR) and disease control rate (DCR). RESULTS: A total of 121 NSCLC patients receiving IO were included. Thirty-three (27.3%) patients presented peripheral blood eosinophilia during treatment. Patients with peripheral eosinophilia presented more frequently non-progression as best overall response to IO (83.3% vs. 58.1%, P=0.014), higher median OS (26.6 vs. 9.5 months, P=0.022) and higher median PFS (13.8 vs. 4.6 months, P=0.013). IrAEs were more common in patients with peripheral eosinophilia (66.7% vs. 36.4%, P=0.003). CONCLUSIONS: This study suggests that peripheral blood eosinophilia may predict better outcomes in NSCLC patients receiving IO, despite being associated with an increased risk of irAEs. According to our findings eosinophils may be involved in immune response against tumor. Routine eosinophils count assessment may be an additional prognostic tool in NSCLC patients receiving IO.

Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia: A Clinical Case.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pulmonary condition characterized by diffuse proliferation of neuroendocrine cells in the epithelium of the bronchial wall. DIPNECH may be easily missed in daily clinical practice and diagnosis is often delayed, which may impair prognosis since this condition is considered a pre-invasive lesion for lung carcinoid tumours. We report a clinical case of DIPNECH in order to discuss the diagnostic and therapeutic approach for this entity, the management of which is not yet well established in the literature. LEARNING POINTS: DIPNECH is a poorly understood lung condition characterized histologically by diffuse proliferation of pulmonary neuroendocrine cells in the bronchial wall, clinically by obstructive respiratory symptoms and radiologically by small airway disease features and pulmonary nodules.DIPNECH is considered to be a preneoplastic lesion within the spectrum of pulmonary neuroendocrine tumours.Treatment is usually guided by the symptoms and prognosis is highly variable.

[First determination of the prevalence of celiac disease in a Portuguese population]. / Primeira determinação de prevalência de doença celíaca numa população Portuguesa.

UNLABELLED: The prevalence of celiac disease is unknown in Portugal. In European countries the prevalence is between 1:200 and 1:400. The incidence obtained through diagnosed cases in the paediatric gastroenterology units in Portugal was 1:3648. To determine the best current celiac disease screening method and its prevalence in a portuguese population, 536 sera of teenagers with 14 years +/- 6 months from Braga town schools were tested as follows: a) total IgA, b) anti-tissue transglutaminase antibodies c) anti-endomysium antibodies (AEA). One female adolescent, with negative AEA and anti-transglutaminase antibodies had a diagnosed celiac disease; this patient was under appropriate diet. Eleven adolescents had positive anti-transglutaminase antibodies and 4 of these had also positive AEA. A jejunal biopsy was carried out on the latter adolescents. Three presented intestinal villous atrophy, 2 a flat mucosa and 1 a moderate atrophy. One female adolescent had a normal mucosa. The prevalence was 1:134, [confidence interval at 95%, 1:53-1:500]. CONCLUSIONS: Presently, total IgA with determination of anti-tissue transglutaminase antibodies is apparently the best screening method; it is less expensive test and, given the use of ELISA, less dependent on the observer. The celiac disease prevalence found in the present study falls within the range of prevalence recently found in other European populations, which implies that the celiac disease is under-diagnosed in Portugal.
