Background: The breathing mechanism has existed since our birth and accompanies us throughout life. Breathing is an important function in the regulatory process of numerous body functions, its optimization can bring many health benefits. However, many children are unaware of the mechanisms of breathing, namely abdominal or diaphragmatic breathing, and in addition to this, many breathe normally through their mouths. Methods: The present study aimed to verify the influence of a short-term breathing exercise program in school-age girls breathing capacity. Fourteen female students aged between 8 and 10 years were selected, from this selection two groups were formed, the control group (CG) with 7 children and the experimental group (EG) with 7. Through a spirometric test, an assessment of breathing capacity (ABC) was carried out for both groups. The GE participated in a program of breathing exercises (BEP) lasting 15 to 20 minutes for 5 weeks. Then, the ABC was performed again for both groups. Discussion: The results demonstrate a significant increase in the values (p

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries. We implemented linear mixed effects models to investigate drivers of species richness among specialized frugivorous fishes across the ~6,000,000 km 2 Amazon Basin, analyzing 29 species from 9 families (10,058 occurrences). Floodplain predictors per subbasin included floodplain forest extent, tree species richness (309,540 occurrences for 2,506 species), water biogeochemistry, flood duration, and elevation, with river order controlling for longitudinal positioning along the river network. We observed heterogeneous patterns of frugivorous fish species richness, which were positively correlated with floodplain forest extent, tree species richness, and flood duration. The natural hydrological regime facilitates fish access to flooded forests and controls fruit production. Thus, the ability of Amazonian floodplain ecosystems to support frugivorous fish assemblages hinges on extensive and diverse seasonally flooded forests. Given the low functional redundancy in fish seed dispersal networks, diverse frugivorous fish assemblages disperse and maintain diverse forests; vice versa, diverse forests maintain more fish species, underscoring the critically important taxonomic interdependencies that embody Amazonian ecosystems. Effective management strategies must acknowledge that access to diverse and hydrologically functional floodplain forests is essential to ensure the long-term survival of frugivorous fish and, in turn, the long-term sustainability of floodplain forests., Competing Interests: Competing interests statement:The authors declare no competing interest.

To assess the effects of a group class physical exercise program on health-related quality of life (HRQOL), physical fitness and activity, and safety in early breast cancer women after treatment, a double-phase trial [16-week control phase (CP) followed by a 16-week intervention phase (IP)] was designed. Outcomes were evaluated at baseline (T1), 8 (T2) and 16 (T3) weeks (CP), and 24 (T4) and 32 (T5) weeks (IP). The primary endpoint was global health status. Out of 82 enrolled patients, 37 completed the IP. Global health status decreased (-10,1; 95% CI -19.8 to -0.4; p  = 0.040) during the CP and stabilized during the IP. Physical and sexual functioning increased during the IP ( p  = 0.008; p  = 0.017), while cardiorespiratory fitness increased in the CP ( p  = 0.004). Upper limb strength and lower limb functionality increased during both phases [CP: p  < 0.0001, p  = 0.001 (surgical and nonsurgical arm), p  = 0.028; IP: p  < 0.0001, p  = 0.002, p  = 0.009]. Body mass index decreased in the IP ( p  = 0.026). Waist circumference increased in the CP ( p  = 0.001) and decreased in the IP ( p  = 0.010); sedentary behaviours and moderate and vigorous physical activity did not change. Adherence to 70% of the sessions was reported in 54% of patients. No serious adverse events related to the intervention were reported. In conclusion, the physical exercise program was able to prevent the decline in global health status and to improve other domains of HRQOL and physical fitness. As physical exercise is not the standard of care in many countries, the implementation of group class programs might be an option.

Objectives: To evaluate the internal consistency and construct validity of the QLQ-MY20 for assessing the quality of life in multiple myeloma survivors in Chile., Methods: This was a cross-sectional study conducted between March 2020 and December 2022. It involved 118 individuals from two public hospitals. The QLQ-C30 and QLQ-MY20 questionnaires were used. Internal consistency was assessed using Cronbach's alpha(α), and construct validity was evaluated through hypothesis testing (Mann-Whitney and Spearman correlation)., Results: The average age of participants was 67.2 years (SD=9.2). Internal consistency for the complete scale was α=0.779, for the "disease symptoms" dimension α=0.671, for the "side effects of treatments" dimension α=0.538, and for the "future perspective" dimension α=0.670. Four of the five construct validity hypotheses were confirmed: women, individuals with worse performance status, those with pain, and those with worse fatigue showed more symptoms., Conclusions: The Chilean version of the QLQ-MY20 demonstrates adequate internal consistency and construct validity.

Amazonia's floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree communities and the critical ecosystem functions they underpin. Here we address this gap by taking a spatially explicit look at Amazonia-wide patterns of tree-species turnover and ecological specialization of the region's floodplain forests. We show that the majority of Amazonian tree species can inhabit floodplains, and about a sixth of Amazonian tree diversity is ecologically specialized on floodplains. The degree of specialization in floodplain communities is driven by regional flood patterns, with the most compositionally differentiated floodplain forests located centrally within the fluvial network and contingent on the most extraordinary flood magnitudes regionally. Our results provide a spatially explicit view of ecological specialization of floodplain forest communities and expose the need for whole-basin hydrological integrity to protect the Amazon's tree diversity and its function., (© 2024.

Purpose: To examine the effectiveness of a supervised exercise training program (SETP) on health-related quality of life (HRQoL) and functional capacity in women with breast cancer (BC) undergoing chemotherapy., Methods: Ninety-three women with early-stage BC were randomly allocated to a SETP plus usual care (exercise, n = 47) or usual care alone (UC, n = 46). The SETP included three sessions per week, combining aerobic and resistance training, conducted concurrently over the chemotherapy. The EORTC Cancer Quality-of-Life-Questionnaire-Core-30 (QLQ-C30) and the BC-specific module (QLQ-BR23) were used to assess HRQoL. Functional capacity was analyzed by maximum voluntary handgrip strength (MVHS) and by the 30-s chair sit-to-stand test (30-s CST). These endpoints were assessed at baseline (t0); middle (t1; after 8 or 12 wk of t0); and at the end of chemotherapy (t2; after 20 wk of t0). Mean changes from baseline were assessed by an intention-to-treat approach., Results: Mixed linear model analyses showed that Exercise group experienced less deterioration in several domains of QLQ-C30 at t2, including in global health status/QoL (Δ = 9.39 units; P = 0.034), QLQ-C30 summary score (Δ = 8.08 units; P < 0.001), physical (Δ = 15.14 units; P < 0.001), role ( Δ = 21.81 units; P < 0.001), cognitive (Δ = 9.16 units; P = 0.032) and social functioning (Δ = 11.67 units; P = 0.038), compared with the UC group. Similarly, Exercise group exhibited significant lower levels of fatigue (Δ = -20.19 units; P < 0.001) and appetite loss (Δ = -13.69 units; P = 0.034), compared with the UC group. Significant between-group differences were observed on MVHS of the tumor/surgery upper limb side (Δ = 2.64 kg; P < 0.001) and contralateral limb (Δ = 2.22 kg; P < 0.001), and on the 30-s CST score (Δ = 3.56repetitions; P < 0.001), favoring the Exercise group. No differences were observed on QLQ-BR23 domains., Conclusions: Exercise training was an effective complementary therapy to prevent the deterioration of HRQoL and functional capacity during chemotherapy in women with early-stage BC., (Copyright © 2023 by the American College of Sports Medicine.)

Purpose: Health literacy is a current Public Health priority in Portugal. The participation of well-informed patients in their care and shared decision making are essential, especially in chronic aggressive and debilitating pathologies such as recurrent or metastatic (R/M) Head and Neck Squamous Cell Carcinoma (HNSCC)., Aims: This study aimed to characterize R/M HNSCC patients' and caregivers' information needs identified by healthcare professionals (HCPs)., Methods: Two online Focus Groups, one with only medical doctors and the other with other HCPs involved in the treatment of R/M HNSCC patients, were conducted, using a modified Metaplan, Lean or adapted PDCA methodology. The discussions were audio recorded in full and content analysis was performed using ATLAS.ti qualitative data analysis software., Results: Topics addressed were diagnosis, treatment, quality of life, and global evaluation. In general, all experts agreed that only essential information should be cautiously given, according to patients' and caregivers' wishes. It was consensual that patients are given the necessary information to adhere to treatment. Two main barriers were identified: one barrier was associated with verbal communication due to the lack of health literacy of these patients, and the other barrier regarded healthcare access. It was also considered important to remind patients of the daily and social activities that they could and should maintain, as well as providing sufficient social resources and problem-solving training to caregivers., Conclusions: This qualitative study highlights the complexity of R/M HNSCC patients' care. Immediate availability of psychologists and psychiatrists should be implemented in all centers that treat HNSCC patients. The differences found between the physicians' Focus Group and other HCPs' Focus Group in some of the addressed topics emphasize the importance of a multidisciplinary and holistic approach, in a biomedical model integrated with a biopsychosocial model., (© 2024.

Antibiotic-resistant bacteria and antibiotic resistance gene (ARGs) loads dissipate through sewage treatment plants to receiving aquatic environments, but the mechanisms that mitigate the spread of these ARGs are not well understood due to the complexity of full-scale systems and the difficulty of source tracking in downstream environments. To overcome this problem, we targeted a controlled experimental system comprising a semicommercial membrane-aerated bioreactor (MABR), whose effluents fed a 4,500-L polypropylene basin that mimicked effluent stabilization reservoirs and receiving aquatic ecosystems. We analyzed a large set of physicochemical measurements, concomitant with the cultivation of total and cefotaxime-resistant Escherichia coli, microbial community analyses, and quantitative PCR (qPCR)/digital droplet PCR (ddPCR) quantification of selected ARGs and mobile genetic elements (MGEs). The MABR removed most of the sewage-derived organic carbon and nitrogen, and simultaneously, E. coli, ARG, and MGE levels dropped by approximately 1.5- and 1.0-log unit mL -1 , respectively. Similar levels of E. coli, ARGs, and MGEs were removed in the reservoir, but interestingly, unlike in the MABR, the relative abundance (normalized to 16S rRNA gene-inferred total bacterial abundance) of these genes also decreased. Microbial community analyses revealed the substantial shifts in bacterial and eukaryotic community composition in the reservoir relative to the MABR. Collectively, our observations lead us to conclude that the removal of ARGs in the MABR is mainly a consequence of treatment-facilitated biomass removal, whereas in the stabilization reservoir, mitigation is linked to natural attenuation associated with ecosystem functioning, which includes abiotic parameters, and the development of native microbiomes that prevent the establishment of wastewater-derived bacteria and associated ARGs. IMPORTANCE Wastewater treatment plants are sources of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs), which can contaminate receiving aquatic environments and contribute to antibiotic resistance. We focused on a controlled experimental system comprising a semicommercial membrane-aerated bioreactor (MABR) that treated raw sewage, whose effluents fed a 4,500-L polypropylene basin that mimicked effluent stabilization reservoirs. We evaluated ARB and ARG dynamics across the raw-sewage-MABR-effluent trajectory, concomitant with evaluation of microbial community composition and physicochemical parameters, in an attempt to identify mechanisms associated with ARB and ARG dissipation. We found that removal of ARB and ARGs in the MABR was primarily associated with bacterial death or sludge removal, whereas in the reservoir it was attributed to the inability of ARBs and associated ARGs to colonize the reservoir due to a dynamic and persistent microbial community. The study demonstrates the importance of ecosystem functioning in removing microbial contaminants from wastewater., Competing Interests: The authors declare no conflict of interest.

Medullary thyroid carcinoma (MTC) is a rare type of neuroendocrine tumor, accounting for 3%-4% of all thyroid cancers. Seventy-five percent are sporadic, of which 60% have pathogenic REarranged during Transfection (RET) somatic mutations. The sporadic RET-mutated MTC poses novel challenges for targeted treatment. The authors present a case of a 60-year-old male diagnosed in 2018 with MTC who underwent total thyroidectomy with sternotomy and bilateral cervical lymph node dissection - pT3N1b R1 L1 V1 Pn0 cM1 (hepatic and lung metastasis). According to the decisions made by the multidisciplinary tumor board, the patient received multiple palliative systemic treatments. Despite an initial response, vandetanib was accompanied by grade 3 high blood pressure and progression after 14 months of treatment. The patient also received cabozantinib, which led to an initial response, but with grade 3 hypertension and skin toxicity. The patient progressed, including symptomatic bone metastasis, after 15 months of treatment. Following the next sequencing genome result, which showed a somatic mutation in the RET M918T gene, the patient was treated with selpercatinib, a highly selective and potent RET inhibitor. The treatment led to clinical and radiological responses without significant toxicities. The objective of this case report is to highlight the impact of innovative treatment and precision medicine on the management of cancer patients, which not only has a direct effect on their survival but also on their quality of life., Competing Interests: The Arcagen project is funded by F.

The phylum Pseudomonadota is amongst the most represented in the environment, with a comparatively lower prevalence in the human oral cavity. The ubiquity of Pseudomonadota and the fact that the oral cavity is the most likely entry portal of bacteria from external sources underlie the need to better understand its occurrence in the interface environment-humans. Yet, the relevance oral Pseudomonadota is largely underexplored in the scientific literature, a gap that this review aims at addressing by making, for the first time, an overview of the diversity and ecology of Pseudomonadota in the oral cavity. The screening of scientific literature and human microbiome databases unveiled 1328 reports of Pseudomonadota in the oral cavity. Most of these belonged to the classes Beta- and Gammaproteobacteria, mainly to the families Neisseriaceae, Campylobacteriaceae, and Pasteurelaceae. Others also regularly reported include genera such as Enterobacter, Klebsiella, Acinetobacter, Escherichia, Burkholderia, or Citrobacter, whose members have high potential to acquire virulence and antibiotic resistance genes. This review provides evidence that clinically relevant environmental Pseudomonadota may colonize humans via oral cavity. The need for further investigation about Pseudomonadota at the environment-oral cavity interface and their role as vectors potentially involved in virulence and antibiotic resistance transmission is demonstrated. KEY POINTS: • Neisseriaceae, Campylobacteriaceae, and Pasteurelaceae are part of the core oral microbiome • Enterobacteriaceae, Acinetobacter, or Burkholderia are frequent in the oral microbiome • Gut dysbiosis may be associated with colonization by ubiquitous oral Pseudomonadota., (© 2022.

Background: Breast cancer is the most common cancer worldwide, and despite remarkable progress in its treatment, the survivors' quality of life is hampered by treatment-related side effects that impair psychosocial and physiological outcomes. Several studies have established the benefits of physical exercise in breast cancer survivors in recent years. Physical exercise reduces the impact of treatment-related adverse events to promote a better quality of life and functional outcomes., Aim: This study aims to provide an overview of systematic reviews and meta-analyses on the effect of physical exercise on the health-related quality of life, cardiorespiratory fitness, muscle strength, and body composition of breast cancer survivors., Methods: PubMed and Cochrane databases were searched for systematic reviews and meta-analyses from January 2010 to October 2022. The main focus was ascertaining the effectiveness of physical exercise in breast cancer survivors undergoing curative treatment (surgery and/or radiotherapy and/or chemotherapy). Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies., Results: A total of 101 studies were identified, and 12 were yielded for final analysis. The eligible studies included nine systematic reviews/meta-analyses, one meta-analysis/meta-regression, and two systematic reviews. The number of randomised clinical trials included in each review varied from 11 to 63, and the number of participants was from 214 to 5761. A positive and significant effect of different physical exercise interventions on health-related quality of life was reported in 83.3% (10 studies) of the eligible studies. Physical exercise also improved cardiorespiratory fitness (3 studies; 25%) and showed to be effective in reducing body weight (3 studies; 25%) and waist circumference (4 studies; 33.3%)., Conclusions: Our results suggest that physical exercise is an effective strategy that positively affects breast cancer survivors' quality of life, cardiorespiratory fitness, and body composition. Healthcare professionals should foster the adoption of physical exercise interventions to achieve better health outcomes following breast cancer treatments., Systematic Review Registration: https://inplasy.com/inplasy-2022-11-0053/, identifier INPLASY2022110053., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Joaquim, Leão, Antunes, Capela, Viamonte, Alves, Helguero and Macedo.)

Introduction: Ovarian cancer is a leading cause of death among women with gynecologic malignancies. The relapse rate is high after platinum-based therapy, with the effectiveness of subsequent treatment lines decreasing over time. Recent data suggest the benefit of maintenance therapy with niraparib in platinum-sensitive recurrent disease., Case Presentations: We report a case series of five women with advanced ovarian cancer and BRCAness phenotype who responded favorably, and in some cases with long-term response, to maintenance therapy with niraparib. Toxicities were as expected and generally manageable. Two patients developed grade 2/3 hematological toxicity, which resolved with treatment suspension and subsequent dose reductions, and one patient reported a rare skin toxicity while responding to full-dose niraparib treatment, which was controlled with photoprotection and sunscreen., Discussion and Conclusions: This case series highlights the role of PARP1/2 inhibitors as a new standard of care as maintenance therapy for recurrent platinum-sensitive high-grade ovarian cancer, irrespective of BRCA status., (© 2022.

Introduction: To evaluate functional state, it is fundamental to have simple instruments that allow for monitoring the course of symptoms and the commitment of the functional status that adult COVID-19 survivors may present. This study aims to evaluate the psychometric properties of the Post COVID-19 Functional Status (PCFS) scale., Material and Methods: A cross-sectional scale validation study was performed. In the content validation 22-health professionals, whom through expert judgment evaluated the scale in the sufficiency, clarity, coherence and relevance categories. In addition, two professionals performed the retest with 20 people who had been infected with COVID-19. In addition, their observations and comments are revealed. The degree of agreement amongst the experts was determined with the Kendall coefficient. For the retest test, the Spearman coefficient was utilized. In all the analyzes, a P value of <.05 was considered., Results: In regards to the content validity, there was agreement between raters only for the relevance category (P=.032). A strong agreement was obtained between two evaluators (Spearman's Rho=.929 for the score). Some of the content terms were adjusted without affecting the general structure of the scale. Of the original 16 items that make up the PCFS scale, none was eliminated., Conclusions: The Spanish version of the PCFS (Chile) was adapted to the cultural context of the country, shows good psychometric characteristics in terms of reliability., (Copyright © 2021 Sociedad Española de Rehabilitación y Medicina Física.

Head and neck cancer (HNC) treatment's toxicities impact several health domains. Exercise training (ET) may be beneficial. This prospective observational study (NCT04996147) aimed to analyse the acute impact of HNC curative multimodal treatment on health-related quality of life (HRQoL), nutritional status, physical and cognitive functions, and ET preferences. Eighteen patients with stage III/IV HNC were evaluated at baseline (T0), and 10 patients were evaluated at the end of treatment (T1), 7 of them after radical chemoradiotherapy (rCRT). At T0, the majority referred a good HRQoL on the EORTC QLQ-C30 questionnaire (median score: 70.8), were moderately malnourished or at risk of malnutrition (78%), recognized the benefits of an ET program, and were willing to participate (78%). After rCRT, there was worsening in HRQoL (75 vs. 50 score, p = 0.014), dysphagia severity (Eating Assessment Tool: 7 vs. 31, p = 0.027; Functional Oral Intake Scale: 6 vs. 4, p = 0.041), handgrip strength (dominant: 40.9 vs. 35.8 kgf, p = 0.027; nondominant: 37.2 vs. 33.9 kgf, p = 0.043), and nutritional status (Patient-Generated Subjective Global Assessment: 7 vs. 18, p = 0.028). HNC patients subjected to radical treatment represent a vulnerable population that might benefit from multimodal supportive care strategies including an ET program.

Metaplastic breast carcinoma (MBC) is a rare and aggressive histologic subtype of cancer. Because of its rarity and heterogeneity, the management of these patients is challenging. Here, we present the case of a rapidly progressive MBC with mesenchymal differentiation in a 37-year-old female, treated with trimodal therapy consisting of neoadjuvant chemotherapy with paclitaxel and carboplatin, followed by dose-dense cyclophosphamide and doxorubicin (ddAC), modified radical left mastectomy, and adjuvant radiotherapy. Despite the need to anticipate the surgery after the first cycle of ddAC, because of a life-treating adverse event, there was a pathologic complete response. Nevertheless, 6.2 months after completing adjuvant radiotherapy, the patient had a recurrence on the central nervous system (CNS) (two lesions), which was managed with excisional biopsy and stereotactic body radiation therapy. The patient also started "complementary" chemotherapy with capecitabine. Still, 18 months after being diagnosed, she died due to CNS disease progression., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Leão et al.)

Background: Public hospital managers in Rio de Janeiro must deal with severe budget costs, which is the only source of income of public hospitals. In this sense, systematic supply chain risk management can contribute to identifying such risks, assessing their severity, and developing mitigating plans, or even revealing the lack of such plans. Private hospital networks must also map their risks since they are facing a diminishing of demand given that unemployment in Brazil, which is growing in the past years, generates an impossibility of affording private healthcare., Objective: The purpose of this paper is to investigate how supply chain risk management is being applied in healthcare supply chains from Rio de Janeiro - Brazil. This study considers supply chains located in the state of Rio de Janeiro. To accomplish this objective, we provide answers to two Research Questions: RQ1 - Is SCRM known as a concept among Rio de Janeiro healthcare supply chains? RQ2 - How are risk identification, risk assessment, and risk mitigation being implemented by companies from the healthcare supply chains in Rio de Janeiro - Brazil?, Method: Our research design is based on four steps: i) Research design; ii) Case selection: iii) Data collection (11 cases selected); iv) Data analysis., Results: The interviews revealed that SCRM is an entirely unknown concept among healthcare supply chains from Rio de Janeiro - Brazil. Managers have empirical knowledge of the risks, and they can identify the most hazardous risks and can come up with solutions to mitigate them, nevertheless, in many situations they do not have the authority or the manpower to implement the solutions, at most, managers implement local risk mitigation initiatives that do not consider the supply chains broader context., Conclusion: The healthcare organizations studied by this paper do not apply SCRM. They only apply local isolated solutions not considering a supply chain scope. This can become hazardous since isolated risk mitigation initiatives are often innocuous and have the potential to generate other risks.

Purpose: Biliary tract obstruction in cancer patients is usually associated with a poor prognosis. The obstruction may cause distressing symptoms, such as pruritus. As this situation occurs mostly in advanced cancer, the primary objective of the treatment is in many cases symptom control and not prolonging life. However, some patients can be candidates for chemotherapy. To see the outcomes of stenting insertion in patients of our oncology center., Methods: A retrospective study of patients who have undergone this procedure between 1 October 2011 and 31 December 2018 was carried out., Results: Insertion of a biliary stent was performed in 171 patients. The most common diagnoses were gastric and colorectal cancers, each with 42 (24%), followed by pancreatic (34 (20%)) and biliary tract cancer (25 (14%)). Most stents (155 (91%)) were placed percutaneously. Complications were seen in 91 (53%) patients and the most common was cholangitis in 48 (53%) patients, and the median survival was 75.5 days (3-1246). A total of 168 (98%) patients were referred to palliative care. In a multivariable analysis, the ECOG performance status was associated with survival, with the ECOG 0, 1, and 2 associated with better survival and peritoneal metastases associated with lower survival., Conclusions: For many patients with advanced cancers, it may not be clear if the benefits of palliative biliary stents outweigh the risks. Therefore, the problem should be discussed with the patients and their families, making clear the goals of care and the potential benefits and risks that can be expected., (© 2020.

Background: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine neoplasia, with high risk of recurrence and metastasis and poor survival. Immune checkpoint inhibitors, like the anti-programmed death-ligand 1 agent avelumab, were recently approved for the treatment of advanced MCC. We, herein, report the first case of advanced MCC with oligoprogression managed with avelumab and local radical treatment., Case Summary: A 61-year-old man was presented to the hospital with sporadic fever and an exudative malodorous mass (10 cm of diameter), located on the right gluteal region. The final diagnosis was MCC, cT4N3M1c (AJCC, TNM staging 8 th edition, 2017), with invasion of adjacent muscle, in-transit metastasis, and bone lesions. Patient started chemotherapy (cisplatin and etoposide), and after six cycles, the main tumor increased, evidencing disease progression. Two months later, the patient started second line treatment with avelumab (under an early access program). After two cycles of treatment, the lesion started to decrease, achieving a major response. Local progression was documented after 16 cycles. However, as the tumor became resectable, salvage surgery was performed, while keeping the systemic treatment with avelumab. Since the patient developed bilateral pneumonia, immunotherapy was suspended. More than 2.5 years after surgery (last 19 mo without systemic therapy), the patient maintains complete local response and stable bone lesions., Conclusion: This report highlights the efficacy and long-term response of avelumab on the management of a chemotherapy resistant advanced MCC, with evidence of oligoprogression, in combination with local radical treatment., Competing Interests: Conflict-of-interest statement: Dr. Marinho reports grants from Merck KGaA, during the conduct of the study; personal fees from Merck KGaA, non-financial support from Servier, non-financial support from Astellas, non-financial support from Roche, non-financial support from Lilly, non-financial support from Merck, outside the submitted work.

Introduction: Febrile neutropenia (FN) is a potentially life-threatening complication of systemic chemotherapy (CT) that often requires hospital admission. Delay in diagnosis and treatment are associated with higher morbidity and mortality., Objective: We aimed to determine the factors that influence FN episodes outcomes in the emergency room (ER)., Methods: This was a retrospective study of all FN episodes (with a collected blood culture [BC]) that occurred between 2012 and 2016 at our institution. FN was defined as a temperature ≥38°C and an absolute neutrophil count (ANC) <1,000/μL, expected to decrease to <500/μL in the following week., Results: Between 2012 and 2016, there were 173 FN episodes in 153/1,947 patients treated with intravenous CT. Most of these episodes (n = 121, 70%) were diagnosed in the ER, 29 in the outpatient clinic, and 23 as inpatients. In the ER, the median time was 36 min from hospital nurse triage to medical observation, and 52 min from medical observation to complete blood count specimen collection. There was a positive BC in 33 FN episodes, 72% with Gram-negative bacteria. A total of 160 FN episodes led to hospital admission and 13 were treated as outpatients. Mortality associated with the FN episode was 15% and an ANC <100/μL was predictive of increased mortality., Conclusion: This study confirms that FN is a serious and common complication of IV CT which must be diagnosed and treated promptly. Profound neutropenia was the only predictive factor of mortality., (© 2020 S. Karger AG, Basel.)

Anaemia is highly prevalent in cancer patients, adversely affects quality of life and impacts survival. The pathogenesis is multifactorial, with iron deficiency being a major and potentially treatable contributor. This study aimed to assess the effectiveness and economic impact of ferric carboxymaltose in chemotherapy-induced anaemia. This prospective cohort study between 2015-2016 of chemotherapy-treated patients for solid tumours, grade ≥2 anaemia and iron deficiency evaluated hematopoietic response four weeks after ferric carboxymaltose treatment. Transfusion rate of all cancer patients treated at our ambulatory unit during the two-year study period (2015-2016) was compared to a retrospective cohort (2013-2014) who received blood transfusion only. Between 2015-2016, 99 patients were included and treated with ferric carboxymaltose, the majority of whom (n = 81) had relative iron deficiency. Mean haemoglobin concentrations improved from 9.2 [6.7-10.8] g/dL to 10.6 [7.8-14.2] g/dL four weeks after treatment. A 26% reduction in the transfusion rate was observed from control retrospective to the prospective study group including ferric carboxymaltose treated patients [relative risk 0.74 (95% CI:0.66-0.83)]. The cost analysis showed a benefit for the use of ferric carboxymaltose in chemotherapy-induced anaemia. This study shows that ferric carboxymaltose is an effective, cost-saving support treatment, reducing the need for allogeneic transfusions saving blood units which are a limited resource.
