RESUMO

People recovered from COVID-19 may still present complications including respiratory and neurological sequelae. In other viral infections, cognitive impairment occurs due to brain damage or dysfunction caused by vascular lesions and inflammatory processes. Persistent cognitive impairment compromises daily activities and psychosocial adaptation. Some level of neurological and psychiatric consequences were expected and described in severe cases of COVID-19. However, it is debatable whether neuropsychiatric complications are related to COVID-19 or to unfoldings from a severe infection. Nevertheless, the majority of cases recorded worldwide were mild to moderate self-limited illness in non-hospitalized people. Thus, it is important to understand what are the implications of mild COVID-19, which is the largest and understudied pool of COVID-19 cases. We aimed to investigate adults at least four months after recovering from mild COVID-19, which were assessed by neuropsychological, ocular and neurological tests, immune markers assay, and by structural MRI and 18FDG-PET neuroimaging to shed light on putative brain changes and clinical correlations. In approximately one-quarter of mild-COVID-19 individuals, we detected a specific visuoconstructive deficit, which was associated with changes in molecular and structural brain imaging, and correlated with upregulation of peripheral immune markers. Our findings provide evidence of neuroinflammatory burden causing cognitive deficit, in an already large and growing fraction of the world population. While living with a multitude of mild COVID-19 cases, action is required for a more comprehensive assessment and follow-up of the cognitive impairment, allowing to better understand symptom persistence and the necessity of rehabilitation of the affected individuals.

RESUMO

Anti-fibroblast antibodies (AFA) have been reported in systemic sclerosis (SSc) and are known to promote fibroblast activation. Aim of this study was to characterize the fine specificity of AFA and to analyze any correlations with clinical parameters associated to fibrosis. To this end, AFA were affinity-purified from a patient with diffuse cutaneous SSc (dcSSc) and interstitial lung disease (ILD). Panning of a phage display peptide library with purified AFA identified the motif . The peptide p121, bearing the AFA-specific motif, was used in ELISA to screen sera from 186 SSc patients and 81 healthy donors. Anti-p121 Ab serum levels were statistically higher in SSc than in healthy groups, and directly associated with dcSSc, reduced FVC (FVC < 70), and ILD. Given these clinical correlates, this study lays the groundwork for the identification of the antigen recognized by anti-p121 Ab, which might represent a novel therapeutic target for ILD.

RESUMO

PURPOSE: Breast cancer (BC) is the most common type of cancer among women in Brazil. Evidence shows that delayed treatment onset is associated with increased mortality. This study aimed to evaluate median days between diagnosis and treatment and factors associated with delayed start of treatment (> 60 days after diagnosis): stage, treatment received, subtype, epidemiological characteristics, and type of healthcare coverage. METHODS: This analysis included 1709 stage I-III BC patients from AMAZONA III, a prospective, observational study, diagnosed from January 2016 to March 2018 in 22 centers in Brazil. RESULTS: The median number of days from diagnosis to beginning of first oncologic treatment was 46 days (IQR 28-75) overall, 43 days (IQR 25-75) for stage I disease, 49 days (IQR 28-81) for stage II, and 44 days (IQR 30-68) for stage III, (p = 0.1180). According to first treatment received, diagnosis-to-treatment interval was 43 days (IQR 29-65) for neoadjuvant chemotherapy and 48 days (IQR 26-81) for surgery. Diagnosis-to-treatment interval was higher in women treated in the public system versus the private system (56 vs. 34 days, p < 0.0001). Patients in the public system had an increased odds of delayed treatment initiation (OR 4.74 95% CI 3.09-7.26, p < .0001). The longer interval from diagnosis to treatment in the public system was independent of clinical stage, type of treatment (systemic vs surgery first), subtype and region of the country. CONCLUSION: By characterizing the delays in care delivery, our study will aid stakeholders to better design interventions and allocate resource to improve timely treatment for breast cancer in Brazil.

RESUMO

PURPOSE: To evaluate the effects of nocturnal asthma on sleep parameters and inflammatory markers according to the severity of the condition in participants in the São Paulo Epidemiologic Sleep Study (EPISONO). METHODS: Data from the 2007 and 2018 editions of the EPISONO study were utilized. Subjects completed validated sleep and respiratory questionnaires, underwent nocturnal polysomnography and spirometry tests, and provided blood samples for the assessment of inflammatory parameters. RESULTS: Of 72 participants (67% women), 53% (n = 38) had intermittent nocturnal asthma symptoms and 47% (n = 34) had persistent asthma (mild, moderate, and severe). Individuals with persistent nocturnal symptoms had a higher body mass index (BMI), were more likely to have respiratory symptoms, and had worse lung function, a higher apnea-hypopnea index (AHI), and higher desaturation index than individuals with intermittent nocturnal symptoms. Positive associations were identified between nocturnal asthma and obstructive sleep apnea (OSA). A higher frequency of OSA was observed in participants with persistent asthma and participants with OSA were more likely to have persistent than intermittent asthma. However, there were no significant differences between the immunological parameters of those with intermittent or persistent asthma. CONCLUSIONS: This study highlights the relevance of nocturnal symptoms as a valuable indicator of asthma severity. The findings also add to the existing body of evidence linking nocturnal asthma and OSA.

RESUMO

Chikungunya virus (CHIKV) has become a significant public health concern due to the increasing number of outbreaks worldwide and the associated comorbidities. Despite substantial efforts, there is no specific treatment or licensed vaccine against CHIKV to date. The E2 glycoprotein of CHIKV is a promising vaccine candidate as it is a major target of neutralizing antibodies during infection. In this study, we evaluated the immunogenicity of two DNA vaccines (a non-targeted and a dendritic cell-targeted vaccine) encoding a consensus sequence of E2CHIKV and a recombinant protein (E2*CHIKV). Mice were immunized with different homologous and heterologous DNAprime-E2* protein boost strategies, and the specific humoral and cellular immune responses were accessed. We found that mice immunized with heterologous non-targeted DNA prime- E2*CHIKV protein boost developed high levels of neutralizing antibodies, as well as specific IFN-γ producing cells and polyfunctional CD4+ and CD8+ T cells. We also identified 14 potential epitopes along the E2CHIKV protein. Furthermore, immunization with recombinant E2*CHIKV combined with the adjuvant AS03 presented the highest humoral response with neutralizing capacity. Finally, we show that the heterologous prime-boost strategy with the non-targeted pVAX-E2 DNA vaccine as the prime followed by E2* protein + AS03 boost is a promising combination to elicit a broad humoral and cellular immune response. Together, our data highlights the importance of E2CHIKV for the development of a CHIKV vaccine.

RESUMO

Background: Adult-onset Still's disease (AOSD) is a rare rheumatic inflammatory condition with an extremely heterogeneous clinical presentation and systemic impairment. Uncommon manifestations may be challenging to manage, especially in patients with previous severe acute SARS-CoV-2 infection. For the first time, we report the case of a patient affected by refractory AOSD presenting with severe pancytopenia as a long-COVID manifestation. The purpose of this case report is to illustrate the clinical presentation, diagnostic and therapeutic management of this unusual manifestation. Moreover, we examine the mechanisms that are potentially responsible for the onset of the pancytopenia observed in our patient. Case presentation: We describe the case of a 40-year-old male who presented with a history of fever for 2 years, arthralgia, maculopapular salmon-pink rash and a previous SARS-CoV-2 infection which required admission to intensive care. The patient's laboratory results revealed elevated inflammatory markers levels (erythrocyte sedimentation rate and C-reactive protein), hyperferritinemia and severe pancytopenia that needed multiple transfusions. A diagnosis of AOSD was made based on clinical and laboratory presentation after excluding neoplastic, infectious and other rheumatic diseases. The previous empirical treatment was not adequate to control the condition; therefore, treatment with high-dose steroids, canakinumab and epoetin alfa was started and led to the resolution of the man's symptoms and a reduction in inflammatory marker levels, whereas blood cell count remained stable without a need for further blood transfusions. The patient is currently under rheumatologic and hematologic follow-up every month. Conclusions: Neither AOSD nor SARS-CoV-2 infection usually manifests with pancytopenia, except in hemophagocytic syndrome or immunodeficient patients, respectively. Identifying the underlying etiology of pancytopenia is mandatory to establish a prompt treatment that generally resolves the disorder. However, in our case, all common causes of pancytopenia were excluded, suggesting a potential manifestation of the long-COVID syndrome. Despite the resolution of the acute infection and the remarkable treatment of AOSD, pancytopenia persists. Herein, we propose for refractory AOSD patients with previous SARS-CoV-2 infection a novel approach to the diagnosis and treatment of pancytopenia.

RESUMO

Background and Objectives: In patients with COVID-19, high-flow nasal cannula (HFNC) and continuous positive airway pressure (CPAP) are widely applied as initial treatments for moderate-to-severe acute hypoxemic respiratory failure. The aim of the study was to assess which respiratory supports improve 28-day mortality and to identify a predictive index of treatment response. Materials and Methods: This is a single-center retrospective observational study including 159 consecutive adult patients with COVID-19 and moderate-to-severe hypoxemic acute respiratory failure. Results: A total of 159 patients (82 in the CPAP group and 77 in the HFNC group) were included in the study. Mortality within 28 days was significantly lower with HFNC compared to CPAP (16.8% vs. 50%), while ICU admission and tracheal intubation within 28 days were significantly higher with CPAP compared to HFNC treatment (32% vs. 13%). We identified an index for survival in HFNC by including three variables easily available at admission (LDH, age, and respiratory rate) and the PaO2/FiO2 ratio at 48 h. The index showed high discrimination for survival with an AUC of 0.88, a negative predictive value of 86%, and a positive predictive value of 95%. Conclusions: Treatment with HFNC appears to be associated with greater survival and fewer ICU admission than CPAP. LDH, respiratory rate, age, and PaO2/FiO2 at 48 h were independently associated with survival and an index based on these variables allows for the prediction of treatment success and the assessment of patient allocation to the appropriate intensity of care after 48 h. Further research is warranted to determine effects on other outcomes and to assess the performance of the index in larger cohorts.

RESUMO

BACKGROUND: Patients with small node-negative HER2-positive breast cancer are commonly treated with paclitaxel and 1 year of adjuvant trastuzumab. We performed a sub-analysis of the ALTTO trial to explore the long-term outcomes of patients with small node-negative tumours. METHODS: The ALTTO trial randomised 8381 patients with early HER2-positive BC treated with adjuvant chemotherapy (anthracycline/taxane- or taxane/carboplatin-based), to trastuzumab (T), lapatinib (L), their sequence (T → L) or their combination (L + T). Patients with tumours ≤3 cm and node-negative were included in this sub-analysis. RESULTS: A total of 2821 patients were analysed (median follow-up of 7 years). The median age was 52 years, and most patients had tumours ≤2 cm (64.3%). The 7-year disease-free survival (DFS) was 88.1% (95% CI: 86.7-89.3%). DFS was similar for arms T, T + L and T⟶L and significantly lower for arm L (stratified log-rank P = 0.031). The 7-year overall survival rate was 95.9% (95% CI: [95.0-96.6%) and the 7-year time-to-distant recurrence was 93.4% (95% CI: 92.3-94.4%). CONCLUSION: With most patients treated with anthracycline-based regimens, ALTTO shows that patients with small tumours treated with trastuzumab and concomitant chemotherapy have excellent long-term outcomes, similar to those of the APT trial. TRIAL REGISTRATION: Clinicaltrials.gov identifier NCT00490139.

RESUMO

PURPOSE: Obstructive sleep apnea (OSA) is a chronic sleep disorder, and its prevalence is increasing worldwide. This disorder has been consistently associated with several comorbidities. Although it is clear that obstructive sleep apnea severity is associated with inflammation, the trigger for this phenomenon continues to puzzle scientists. Here, we investigated the relationship between obstructive sleep apnea severity and immune parameters. METHODS: In this cross-sectional epidemiological research, we analyzed the immune profile of 461 adults according to OSA severity (mild, moderate, and severe) and oxygen saturation. RESULTS: The hallmark of OSA severity - the apnea-hypopnea index (AHI) - weakly correlated with an inflammatory profile. However, individuals who experienced lower oxygen saturation were more likely to exhibit higher total leukocyte and neutrophil counts, a higher neutrophil-lymphocyte ratio (NLR), and an increased concentration of C-reactive protein. CONCLUSION: Our findings indicated that oxygen saturation is a predictor of inflammation during OSA and should be considered crucial in disease diagnostic and treatment strategies.

RESUMO

BACKGROUND: Psoriatic arthritis (PsA) is a chronic, immune-mediated, spondyloarthropathy characterised by musculoskeletal signs and symptoms with associated joint pain and tenderness. The average worldwide PsA prevalence is 133/100,000, while in the Italian population is 90-420/100,000. Traditionally, nonsteroidal anti-inflammatory drugs, glucocorticoid, and disease-modifying antirheumatic drugs have been used in the treatment of PsA. However, for those patients who are not adequately controlled with conventional therapies, the new biologics compounds represent a valid option. Biologic therapies have been shown to be more effective but also more expensive than conventional systemic treatments. Based on the CHRONOS study, the economic analyses presented in this paper aim to assess the annualised direct costs and the cost-per-responder of biologics in a real-world context assuming the Italian National Health System perspective. METHODS: The economic assessments were carried out on the overall cohort of patients, and on the tumour necrosis factor alpha inhibitors (TNFi) and the secukinumab subgroup, the most prescribed biologic therapies within the CHRONOS study. RESULTS: The annual economic impact of PsA in the overall group was €12,622, €11,725 in the secukinumab subgroup, and €12,791 in the TNFi subgroup. Biologics absorbed the main expenditure costs in the treatment of PsA accounting for about the 93% of total costs. At 6 months, secukinumab performed better in all the considered outcomes: cost-per-responder according to EULAR DAS28 and ACR50 response criteria were €12,661- €28,975, respectively, while they were €13,356 - €33,368 in the overall cohort and €13,138 - €35,166 in the TNFi subgroup. At 12 months secukinumab remained the subgroup with the lowest cost-per-responder ratio in EULAR DAS28 and ACR50 response criteria, while TNFi subgroup was the lowest one considered the ACR20. CONCLUSION: Despite some potential methodological limitations, our cost-per-response analysis provides physicians and payers additional insights which can complement the traditional risk-benefit profile assessment and drive treatment decisions.

RESUMO

Zizyphus lotus L. is a perennial shrub particularly used in Algerian folk medicine, but little is known concerning the lipophilic compounds in the most frequently used parts, namely, root bark, pulp, leaves and seeds, which are associated with health benefits. In this vein, the lipophilic fractions of these morphological parts of Z. lotus from Morocco were studied by gas chromatography-mass spectrometry (GC-MS), and their antiproliferative and antimicrobial activities were evaluated. GC-MS analysis allowed the identification and quantification of 99 lipophilic compounds, including fatty acids, long-chain aliphatic alcohols, pentacyclic triterpenic compounds, sterols, monoglycerides, aromatic compounds and other minor components. Lipophilic extracts of pulp, leaves and seeds were revealed to be mainly composed of fatty acids, representing 54.3-88.6% of the total compounds detected. The leaves and seeds were particularly rich in unsaturated fatty acids, namely, (9Z,12Z)-octadeca-9,12-dienoic acid (2431 mg kg-1 of dry weight) and (9Z)-octadec-9-enoic acid (6255 mg kg-1 of dry weight). In contrast, root bark contained a high content of pentacyclic triterpenic compounds, particularly betulinic acid, accounting for 9838 mg kg-1 of dry weight. Root bark extract showed promising antiproliferative activity against a triple-negative breast cancer cell line, MDA-MB-231, with a half-maximal inhibitory concentration (IC50) = 4.23 ± 0.18 µg mL-1 of extract. Leaf extract displayed interesting antimicrobial activity against Escherichia coli, methicillin-sensitive Staphylococcus aureus and Staphylococcus epidermis, presenting minimum inhibitory concentration (MIC) values from 1024 to 2048 µg mL-1 of extract. Our results demonstrate that Zizyphus lotus L. is a source of promising bioactive components, which can be exploited as natural ingredients in pharmaceutical formulations.

RESUMO

Background and objectives: COVID-19 is associated with an aberrant inflammatory response that may trigger new-onset cardiac arrhythmias. The aim of this study was to assess the mortality risk in hospitalized COVID-19 patients according to IL-6 serum levels and new-onset atrial fibrillation (AF) according to PaO2/FiO2 stratification. Materials and Methods: 175 COVID-19 patients (25 new-onset AF, 22 other types of AF and 128 no-AF) were included in this single-center, retrospective study; clinical and demographic data, vital signs, electrocardiograms and laboratory results were collected and analyzed. The primary outcome of the study was to evaluate the mortality rate in new-onset AF patients according to IL-6 serum levels and PaO2/FiO2 stratification. Results: The incidence of new-onset AF in the study population was 14.2%. Compared to the no-AF group, new-onset AF patients were older with a positive history of chronic kidney disease and heart failure, had higher IL-6, creatinine and urea serum levels whereas their platelet count was reduced. After PaO2/FiO2 stratification, 5-days mortality rate was higher in new-onset AF patients compared to patients with other types of AF and no-AF patients, and mortality risk increases 5.3 fold compared to no-AF (p = 0.0014) and 4.8 fold compared to other forms of AF (p = 0.03). Conclusions: New-onset AF is common in COVID-19 patients and is associated with increased IL-6 serum levels and early mortality. Further studies are needed to support the use of IL-6 as an early molecular target for COVID-19 patients to reduce their high rate of mortality.

RESUMO

Conventional dendritic cells (cDCs) are specialized in antigen presentation. In the mouse spleen, cDCs are classified in cDC1s and cDC2s, and express DEC205 and DCIR2 endocytic receptors, respectively. Monoclonal antibodies (mAbs) αDEC205 (αDEC) and αDCIR2 have been fused to different antigens to deliver them to cDC1s or cDC2s. We immunized mice with αDEC and αDCIR2 fused to an antigen using Poly(I:C) as adjuvant. The initial immune response was analyzed from days 3 to 6 after the immunization. We also studied the influence of a booster dose. Our results showed that antigen targeting to cDC1s promoted a pro-inflammatory TH 1 cell response. Antigen targeting to cDC2s induced TFH cells, GCs, and plasma cell differentiation. After boost, antigen targeting to cDC1s improved the TH 1 cell response and induced TH 1-like TFH cells that led to an increase in specific antibody titers and IgG class switch. Additionally, a population of regulatory T cells was also observed. Antigen targeting to cDC2s did not improve the specific antibody response after boost. Our results add new information on the immune response induced after the administration of a booster dose with αDEC and αDCIR2 fusion mAbs. These results may be useful for vaccine design using recombinant mAbs.

RESUMO

OBJECTIVES: To stratify adult-onset Still's disease (AOSD) patients in distinct clinical subsets to be differently managed, by using a multi-dimensional characterization. METHODS: AOSD patients were evaluated by using a hierarchical unsupervised cluster analysis comprising age, laboratory markers systemic score and outcomes. The squared Euclidean distances between each pair of patients were calculated and put into a distance matrix, which served as the input clustering algorithm. Derived clusters were descriptively analysed for any possible difference. RESULTS: Four AOSD patients clusters were identified. Disease onset in cluster 1 was characterized by fever (100%), skin rash (92%) and arthritis (83%), with the highest ferritin levels [mean (S.D.) 14 724 (6837) ng/ml]. In cluster 2, the onset was characterized by fever (100%), arthritis (100%) and liver involvement (90%), together with the highest CRP levels [288.10 (46.01) mg/l]. The patients in cluster 3 presented with fever (100%), myalgia (96%) and sore throat (92%). The highest systemic score values [8.88 (1.70)] and the highest mortality rate (54.2%) defined cluster 3. Fever (100%) and arthritis (90%) were the symptoms at the onset in cluster 4, which was characterized by the lowest ferritin and CRP levels [1457 (1298) ng/ml and 54.98 (48.67) mg/l, respectively]. CONCLUSION: Four distinct phenotypic subgroups in AOSD could be suggested, possibly associated with different genetic background and pathogenic mechanisms. Our results could provide the basis for a precision medicine approach in AOSD in an attempt to find a clinical and laboratory multidimensional stratification and characterization, which would drive a tailored therapeutic approach in these patients.

RESUMO

OBJECTIVES: In rheumatoid arthritis (RA), "traditional" cardiovascular (CV) risk factors continue to be underdiagnosed and undertreated, thus increasing the risk of developing atherosclerosis. In this work, we evaluated the occurrence and predictive factors of "traditional" cardiovascular risk factors, with a focus on high blood pressure (HBP), type 2 diabetes (T2D), and metabolic syndrome (MetS), in participants with RA, in a 3-year, multicentre, prospective, observational study. METHODS: To assess the occurrence and predictive factors of HBP, T2D, and MetS, consecutive participants with RA, admitted to Italian Rheumatology Units, were evaluated in the GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) cohort, a 3-year, multicentre, prospective, observational study. RESULTS: In the present evaluation, 841 participants, who were fully followed up with 3-year of prospective follow-up were assessed. At the end of follow-up, a significant increased incidence of HBP, T2D, and MetS was recorded. Assessing predictive factors, the mean values of C-reactive protein during the follow-up were independent predictors of occurrence of those comorbidities, whereas participants maintaining remission showed a significant lower risk. Furthermore, therapy with hydroxychloroquine (HCQ) reduced the risk of occurrence of T2D and MetS. CONCLUSIONS: An increased incidence of HBP, T2D, and MetS was observed in assessed participants, prospectively followed-up. Furthermore, the analysis of predictive factors suggested that the rheumatoid pro-inflammatory process could increase the occurrence of these comorbidities. Conversely, metabolic and cardiovascular benefits of maintaining remission as well as of therapy with HCQ were reported.

RESUMO

OBJECTIVES: To evaluate the health-related quality of life (HRQoL), disease activity, treatment adherence, and work ability in the real-world setting in patients with axial spondyloarthritis (axSpA). METHODS: QUASAR was a prospective 12-month, observational study involving 23 rheumatology centres across Italy, including adult patients with axSpA according to the Assessment of SpondyloArthritis International Society (ASAS) criteria. Patients were followed at baseline, 3, 6, and 12 months for disease activity and health-related QoL (HRQoL), treatment adherence and work ability. Regression analysis was used to assess the association between treatment and outcome variables. RESULTS: 413 (80.7%) out of axSpA 512 patients were diagnosed with ankylosing spondylitis (AS) and 99 (19.3%) with non-radiographic axSpA (nr-axSpA). Nr-axSpA and AS patients had similar baseline disease activity and HRQoL. Biologic disease-modifying anti-rheumatic drugs (bDMARDs) were the most frequent medication (n=426, 83.2%). Over the 1-year follow-up, disease activity measures (joint pain and swelling, CRP, global assessment, BASDAI, ASDAS), HRQoL and work ability significantly improved, while few differences emerged between nr-axSpA and AS patients. Treatment satisfaction and adherence questionnaires improved over the 12 months. Patients treated with bDMARDs showed improved outcomes for disease activity measures and HRQoL variables, greater benefit observed in patients with AS. CONCLUSIONS: We found clinical and HRQoL improvement over 1 year in a large, real-world population of nr-axSpA and AS patients treated with bDMARDs or conventional synthetic DMARDs.

RESUMO

PURPOSE OF REVIEW: The article reviews the consequences of estrogen deprivation during endocrine therapy for breast cancer and provides an update on alternative therapies for the management of symptoms. RECENT FINDINGS: Endocrine therapy has progressed substantially in recent years, and its use is recommended for all breast cancer patients expressing hormone receptors. The main adverse events of this treatment can be controlled with medications and nonpharmacological measures. Antidepressants are effective in controlling vasomotor symptoms. Vaginal discomfort can be treated with local lubricants and pelvic floor physiotherapy, which may help in sexual dysfunction. Pathophysiological mechanisms of musculoskeletal symptoms during aromatase inhibitors treatment are not well understood, but some studies evaluating treatment with duloxetine, yoga, and acupuncture have shown some benefits. For prevention of bone loss, patients with risk factors should be offered bisphosphonates or denosumab. Individualization of treatment is crucial. Consideration should be given to therapy effects on quality of life, and strategies for controlling associated symptoms should be offered.

RESUMO

The COVID-19 pandemic has had negative effects on health-care workers. The rapid growth of the disease has led to overwhelmed health-care systems, overcrowded hospitals, an insufficient number of health-care professionals and shortages of medical equipment. The potential exposure of front-line health-care workers during the COVID-19 outbreak has led to self-isolation and the appearance of adverse feelings such as stress, anxiety and fear. All these factors, combined with an increased workload and extra and changed shifts, are determinants of a sleep-loss process that may result in insomnia. The exacerbated pro-inflammatory milieu caused by insomnia and sleep deprivation present in health professionals may therefore make them more prone to developing severe COVID-19 if infected and/or aggravate the symptoms of the disease. Keeping these professionals healthy and doing everything possible to prevent them from being infected with COVID-19 should be a top priority. As part of this effort, we must be aware of the important effects of insomnia on the immune systems of these professionals and take all possible measures to counter these effects.

RESUMO

To establish the more relevant questions oncologic patients may have during cancer treatment. Cross-sectional observational study with all patients undergoing chemotherapy or radiotherapy for cancer in a Brazilian health institution. A questionnaire with open and close questions about cancer diagnosis, treatment, and prognosis was applied. A total of 198 patients were evaluated of whom 122 (62%) were female and 80% of the patients were between 50 and 89 years old. Sixty-one percent of women and 62% of men had questions about cancer diagnosis and treatment. Although questions about nutrition were the most frequent for all patients (72% of men and 48% of women), treatment short- and long-term consequences were a concern for 31% of men and treatment effects on esthetics for 21% of women. After having been informed by the oncology team about their diagnosis and treatment, 49% of the patients also searched for other sources of information. Thirty-eight patients (20%) searched for alternative treatments for cancer. About half of the patients searched for other sources of information after having been informed by the oncology team about their cancer diagnosis and treatment. The present study reinforces the importance for the oncologic health team to spend sufficient time with patients in order to clarify doubts about cancer diagnosis and treatment.

RESUMO

Neuromodulation of deep brain structures (deep brain stimulation) is the current surgical procedure for treatment of Parkinson's disease (PD). Less studied is the stimulation of cortical motor areas to treat PD symptoms, although also known to alleviate motor disturbances in PD. We were able to show that optogenetic activation of secondary (M2) motor cortex improves motor functions in dopamine-depleted male mice. The stimulated M2 cortex harbors glutamatergic pyramidal neurons that project to subcortical structures, critically involved in motor control, and makes synaptic contacts with dopaminergic neurons. Strikingly, optogenetic activation of M2 neurons or axons into the dorsomedial striatum increases striatal levels of dopamine and evokes locomotor activity. We found that dopamine neurotransmission sensitizes the locomotor behavior elicited by activation of M2 neurons. Furthermore, combination of intranigral infusion of glutamatergic antagonists and circuit specific optogenetic stimulation revealed that behavioral response depended on the activity of M2 neurons projecting to SNc. Interestingly, repeated M2 stimulation combined with l-DOPA treatment produced an unanticipated improvement in working memory performance, which was absent in control mice under l-DOPA treatment only. Therefore, the M2-basal ganglia circuit is critical for the assembly of the motor and cognitive function, and this study demonstrates a therapeutic mechanism for cortical stimulation in PD that involves recruitment of long-range glutamatergic projection neurons.SIGNIFICANCE STATEMENT Some patients with Parkinson's disease are offered treatment through surgery, which consists of delivering electrical current to regions deep within the brain. This study shows that stimulation of an area located on the brain surface, known as the secondary motor cortex, can also reverse movement disorders in mice. Authors have used a brain stimulation technique called optogenetics, which allowed targeting a specific type of surface neuron that communicates with the deep part of the brain involved in movement control. The study also shows that a combination of this stimulation with drug treatment might be useful to treat memory impairment, a kind of cognitive problem in Parkinson's disease.
