Introduction The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency.Methods At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output.Results Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19.Discussion Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.
The concordance study of the portable camera FLIR C5 for detecting asymmetry of skin temperature in patients with stroke sequelae
(2023) ALFIERI, F. M.; SANTOS, A. C. A. dos; DIAS, C. da Silva; BATTISTELLA, L. R.
BACKGROUND: Low-cost portable infrared cameras are increasingly used for health assessments, especially for investigating the skin temperature of the whole body. However, some of these devices have not yet been tested for agreement with high-resolution cameras. Therefore, the objective of this study was to test the agreement of FLIR C5, a portable infrared thermographic camera, compared to the FLIR T650sc, a high-quality and high-resolution thermographic device, for detecting thermal asymmetry between both sides of the body of patients with motor sequelae after stroke. MATERIALS AND METHODS: This is an observational and cross-sectional study conducted in a physical rehabilitation facility with 14 patients with stroke sequelae. Participants had their temperature simultaneously measured by FLIR T650sc and FLIR C5 infrared thermography cameras and analyzed with the software FLIR Tools®. The temperature difference of each ROI measured by both cameras was compared with Lin's Concordance Correlation Coefficient (rho or ρc) and Bland Altman the limits of agreement (LOA). RESULTS: the temperatures measured by FLIR C5 were lower than those measured by FLIR T650sc, regardless of the region of interest or side (-0.65, SD 1.44). We observed that the general concordance was classified as adequate to excellent (ρc=0.859; 95%CI 0.817-0.901; p<0.001) and that the forearm and leg in the posterior view presented the sites with the best associations between the temperature readings of FLIR C5 and FLIR T650sc. CONCLUSIONS: The temperature asymmetry usually found among patients with stroke sequelae may be assessed by the portable infrared thermographic camera FLIR C5, given its suitable concordance with FLIR T650sc.

Impaired cardiorespiratory fitness and endothelial function after SARS-CoV-2 infection in a sample of mainly immunocompromised youth
(2023) ASTLEY, Camilla; PRADO, Danilo Marcelo Leite do; SIECZKOWSKA, Sofia Mendes; ESTEVES, Gabriel P.; SUGUITA, Priscila; FINK, Thais; LINDOSO, Livia; MATSUO, Olivia; MARTINS, Fernanda; BAIN, Vera; PEREIRA, Maria Fernanda Badue; MARQUES, Heloisa Helena; MALLUF, Adriana; LEAL, Gabriela Nunes; SILVA, Clovis Artur; ROSCHEL, Hamilton; GUALANO, Bruno
This study aimed to compare cardiopulmonary fitness and endothelial function 6 months after hospital diagnosis in a sample mainly comprising immunocompromised patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection versus noninfected controls. Youth (n = 30; age: 14 yr; 60% females) with confirmed SARS-CoV-2 seen in a tertiary hospital of Sao Paulo, Brazil, were matched by propensity score based on BMI, age, sex, and pre-existing diseases with a control group who had not been tested positive for SARS-CoV-2 infection (n = 30; age: 15 yr; 50% females). Cardiopulmonary fitness (by means of a cardiopulmonary exercise test: CPET) and brachial flow-mediated dilation (%b-FMD) were assessed 3-6 mo after diagnosis. Patients were matched by propensity score based on BMI, age, sex and pre-existing diseases, if any, with a control group who had not been tested positive for SARS-CoV-2. Compared with controls, patients with COVID-19 showed reduced ventilatory anaerobic threshold (VAT) and peak exercise time and minute ventilation/maximum voluntary ventilation (V_E/MVV) (all P < 0.01). Brachial endothelial function variables were all adjusted for body surface area (BSA). Patients with COVID-19 had decreased %b-FMD (3.6 vs. 5.4; P = 0.03) mean and positive flow (P = 0.02 and P = 0.03, respectively) versus controls. Adjusted linear regression models exploring associations between CPET variables, %b-FMD and the potential predictors post-COVID-19 syndrome, number of symptoms, hospitalization, and COVID severity did not detect significant associations, except for total shear rate in hospitalization (coefficient: -65.07 [95%CI -119.5;-10.5], P = 0.02). Immunocompromised and previously healthy children and adolescents with COVID-19 presented with impaired exercise capacity and endothelial dysfunction when compared with their noninfected counterparts, but the mechanisms remain unknown.
OPRM1 and BDNF polymorphisms associated with a compensatory neurophysiologic signature in knee osteoarthritis patients
(2023) GONCALVES, Fernanda de Toledo; MARQUES, Lucas Murrins; PESSOTTO, Anne Victorio; BARBOSA, Sara Pinto; IMAMURA, Marta; SIMIS, Marcel; FREGNI, Felipe; BATTISTELLA, Linamara
Objective: The present study investigated the relationship between three genetic polymor-phisms of OPRM1 (rs1799971 -A118G and rs1799972 -C17T) and BDNF (rs6265 -C196T) and EEG-measured brain oscillations in Knee Osteoarthritis (KOA) patients.Materials and Methods: We performed a cross-sectional analysis of a cohort study (DEFINE cohort), KOA arm, with 66 patients, considering demographic (age, sex, and education), clinical (pain intensity and duration), OPRM1 (rs1799971 -A118G and rs1799972 -C17T) and BDNF (rs6265 -C196T) genotypes, and electrophysiological measures. Brain oscillations relative power from Delta, Theta, Alpha, Low Alpha, High Alpha, Beta, Low Beta and High Beta oscillations were measured during resting state EEG. Multivariate regression models were used to explore the main brain oscillation predictors of the three genetic polymorphisms.Results: Our findings demonstrate that Theta and Low Beta oscillations are associated with the variant allele of OPRM1-rs1799971 (A118G) on left frontal and left central regions, respectively, while Alpha brain oscillation is associated with variant genotypes (CT/TT) of BDNF-rs6265 on frontal (decrease of oscillation power) and left central (increase of oscillation power) regions. No significant model was found for OPRM1-rs1799972 (C17T) in addition to the inclusion of pain intensity as a significant predictor of this last model.Conclusion: One potential interpretation for these findings is that polymorphisms of OPRM1 that is involved with endogenous pain control lead to increased compensatory oscillatory mechanisms, characterized by increased theta oscillations. Along the same line, polymorphisms of the BDNF lead to decreased alpha oscillations in the frontal area, likely also reflecting the disruption of resting states to also compensate for the increased injury associated with knee OA. It is possible that these polymorphisms require additional brain adaption to the knee OA related injury.(c) 2023 Published by Elsevier Masson SAS.
Robotic-Assisted Gait Training (RAGT) in Stroke Rehabilitation: A Pilot Study
(2023) NEVES, Mariana Vita Milazzotto; FURLAN, Leonardo; FREGNI, Felipe; BATTISTELLA, Linamara Rizzo; SIMIS, Marcel
Objective: To compare the effects of 2 types of robotic-assisted gait training (RAGT) devices that have been used in stroke rehabilitation. Design: Retrospective cohort.Setting: Rehabilitation hospital.Participants: 24 community dwelling people with stroke (N=24).Interventions: RAGT with either an exoskeleton (Lokomat) (mean age=53.8 years; 30% men; mean duration of stroke =17.8 months) or an end-effector (G-EO) (mean age=50.5 years; 77.8% men; mean duration of stroke =13.11) delivered 3 times per week (36 sessions total).Main Outcome Measures: The following tests/scales were employed before and after RAGT: Functional Ambulation Categories (FACs), timed Up and Go (TUG), 10-Meter Walk Test (10MWT), 6 -Minute Walk Test (6MWT), Trunk Impairment Scale, Dynamic Gait Index (DGI), Berg Balance Scale (BBS), and ability to climb stairs (time to climb 6 steps of 15 cm each; ability to climb stairs).Results: There were 5 dropouts, all from the G-EO group. At the end, 10 participants in the Lokomat and 9 in the G-EO group completed the intervention. From pre-to post-RAGT, G-EO patients improved on all functional tests/scales, whereas Lokomat patients improved only on the TUG, DGI, and BBS. Most patients showed improvements above the relative smallest real difference in the TUG, 10MWT, and 6MWT.Conclusions: Both end-effectors and exoskeletons may improve clinically relevant aspects of walking function. However, this study had a small sample, was retrospective, non-randomized, and had a significant number of drop-outs, therefore its findings should be interpreted carefully. Future studies are needed for investigating potential differences in clinical results, side effects, contraindications, and cost effectiveness between these 2 different types of RAGT.(c) 2023 The Authors.
Hemoperitoneum after a Bothrops snakebite: Case report
(2024) RIBEIRO, Adriana Baqueiro Abad; SANTORO, Marcelo Larami; DUARTE, Marcelo Ribeiro; VIRGULINO, Cristiana Cruz; OLIVEIRA, Gerson Sobrinho Salvador de; FRANCA, Francisco Oscar de Siqueira
Snakebites are frequent in tropical countries. Brazil has an average of 27,000 cases per year, with a fatality rate of 0.5%, and the Bothrops genus is the most common causative agent, accounting for about 70-90% of the accidents. This report describes a case of human envenomation by a juvenile Bothrops jararaca snake in Sa similar to o Paulo, Brazil, in a 71 years-old man, previously healthy. He presented a life-threatening envenomation, which developed to severe hypotension, acute kidney injury and extensive peritoneal hemorrhage. The hemoperitoneum was diagnosed due to persistent hypotension associated with anemia, pain and gastrointestinal complaints. Abdominal Computed Tomography scans showed a moderate to large amount of presumable hematic material inside the abdominal cavity, predominantly in the perihepatic and perisplenic spaces. The intra-abdominal hemorrhage was not surgically addressed, and the patient was discharged 5 days after hospitalization, with the progressive absorption of the hemoperitoneum. Systemic bleeding is one of the complications and main causes of death in Bothrops envenomations. Acute peritoneal hemorrhage is one of these serious complications that must be carefully addressed since its management must take into account the risk of bleeding caused by toxins that affect hemostasis. The case described highlights the importance of early diagnosis and adequate management of this potentially fatal complication in snakebites.
A model for personalized diagnostics for non-specific low back pain: the role of the myofascial unit
(2023) SIKDAR, Siddhartha; SRBELY, John; SHAH, Jay; ASSEFA, Yonathan; STECCO, Antonio; DESTEFANO, Secili; IMAMURA, Marta; GERBER, Lynn H.
Low back pain (LBP) is the leading cause of disability worldwide. Most LBP is non-specific or idiopathic, which is defined as symptoms of unknown origin without a clear specific cause or pathology. Current guidelines for clinical evaluation are based on ruling out underlying serious medical conditions, but not on addressing underlying potential contributors to pain. Although efforts have been made to identify subgroups within this population based on response to treatment, a comprehensive framework to guide assessment is still lacking. In this paper, we propose a model for a personalized mechanism-based assessment based on the available evidence that seeks to identify the underlying pathologies that may initiate and perpetuate central sensitization associated with chronic non-specific low back pain (nsLBP). We propose that central sensitization can have downstream effects on the ""myofascial unit"", defined as an integrated anatomical and functional structure that includes muscle fibers, fascia (including endomysium, perimysium and epimysium) and its associated innervations (free nerve endings, muscle spindles), lymphatics, and blood vessels. The tissue-level abnormalities can be perpetuated through a vicious cycle of neurogenic inflammation, impaired fascial gliding, and interstitial inflammatory stasis that manifest as the clinical findings for nsLBP. We postulate that our proposed model offers biological plausibility for the complex spectrum of clinical findings, including tissue-level abnormalities, biomechanical dysfunction and postural asymmetry, ecological and psychosocial factors, associated with nsLBP. The model suggests a multi-domain evaluation that is personalized, feasible and helps rule out specific causes for back pain guiding clinically relevant management. It may also provide a roadmap for future research to elucidate mechanisms underlying this ubiquitous and complex problem.

(2023) BIN, Kaio Jia; PRETTO, Lucas Ramos De; SANCHEZ, Fabio Beltrame; CASTRO, Fabio Pacheco Muniz De Souza e; RAMOS, Vinicius Delgado; BATTISTELLA, Linamara Rizzo
Background: Since the COVID-19 pandemic, there has been a boost in the digital transformation of the human society, where wearable devices such as a smartwatch can already measure vital signs in a continuous and naturalistic way; however, the security and privacy of personal data is a challenge to expanding the use of these data by health professionals in clinical follow-up for decision-making. Similar to the European General Data Protection Regulation, in Brazil, the Lei Geral de Protecao de Dados established rules and guidelines for the processing of personal data, including those used for patient care, such as those captured by smartwatches. Thus, in any telemonitoring scenario, there is a need to comply with rules and regulations, making this issue a challenge to overcome.Objective: This study aimed to build a digital solution model for capturing data from wearable devices and making them available in a safe and agile manner for clinical and research use, following current laws.Methods: A functional model was built following the Brazilian Lei Geral de Protecao de Dados (2018), where data captured by smartwatches can be transmitted anonymously over the Internet of Things and be identified later within the hospital. A total of 80 volunteers were selected for a 24-week follow-up clinical trial divided into 2 groups, one group with a previous diagnosis of COVID-19 and a control group without a previous diagnosis of COVID-19, to measure the synchronization rate of the platform with the devices and the accuracy and precision of the smartwatch in out-of-hospital conditions to simulate remote monitoring at home.Results: In a 35-week clinical trial, >11.2 million records were collected with no system downtime; 66% of continuous beats per minute were synchronized within 24 hours (79% within 2 days and 91% within a week). In the limit of agreement analysis, the mean differences in oxygen saturation, diastolic blood pressure, systolic blood pressure, and heart rate were -1.280% (SD 5.679%), -1.399 (SD 19.112) mm Hg, -1.536 (SD 24.244) mm Hg, and 0.566 (SD 3.114) beats per minute, respectively. Furthermore, there was no difference in the 2 study groups in terms of data analysis (neither using the smartwatch nor the gold-standard devices), but it is worth mentioning that all volunteers in the COVID-19 group were already cured of the infection and were highly functional in their daily work life.Conclusions: On the basis of the results obtained, considering the validation conditions of accuracy and precision and simulating an extrahospital use environment, the functional model built in this study is capable of capturing data from the smartwatch and anonymously providing it to health care services, where they can be treated according to the legislation and be used to support clinical decisions during remote monitoring.

(2023) PLAPLER, Perola Grinberg; CECATTO, Rebeca Boltes; SOCOLOWSKI, Mariela Diament; MARTINS, Fernanda
Women and men can have the same illnesses, but with different prevalence and reactions to symptoms. OBJECTIVE: This study aimed to emphasize that distinct traits between men and women require a different approach for each of them.METHODS: PubMed and Google Scholar were searched using the following terms: Disability Evaluations, Women's health, Osteoporosis, Osteoarthritis,RESULTS/CONCLUSION: Disease management can go beyond the symptoms, assessing the long-term consequences and possibly the disabilities they can generate, compromising the quality of life of the person, his/her family members, and eventually caregivers.
Functional and Neural Correlates Associated with Conditioned Pain Modulation in Patients with Chronic Knee Osteoarthritis Pain: A Cross-Sectional Study
(2023) SIMIS, Marcel; PACHECO-BARRIOS, Kevin; VASQUEZ-AVILA, Karen; REBELLO-SANCHEZ, Ingrid; PARENTE, Joao; CASTELO-BRANCO, Luis; MARDUY, Anna; MELO, Paulo S. de; IMAMURA, Marta; BATTISTELLA, Linamara; FREGNI, Felipe
In this study, we aimed to assess the factors that predict a dysfunctional conditioned pain modulation (CPM) in chronic knee OA. Methods: This is a cross-sectional analysis of patients with chronic knee OA from a prospective cohort study in Brazil (n = 85). We performed linear and logistic multivariate regression models using the purposeful selection approach to test the relationship between the CPM in both knees (average) as a dependent variable and demographics, clinical, and neurophysiological as independent variables. Results: A significant negative association between WOMAC pain scores and CPM (beta: 0.13) was found. This association was modified by the subjects' race, being stronger in the non-white subjects. In our logistic regression models, pain intensity indexed with the WOMAC pain scale remained a significant association with dichotomized CPM. Furthermore, a significant CPM association with balance, indexed with the Berg Balance score, was evidenced ( beta: 0.04). Neurophysiological variables showed a significant negative relationship with CPM, such as the relative power of delta oscillations in the frontal area ( beta: 3.11) and central area ( beta: 3.23). There was no significant relationship between CPM and the following domains: cognitive, emotion, sleep, opioid receptor polymorphisms, and intrinsic variables of OA disease. There was no association of CPM with TMS-indexed inhibitory markers. Conclusions: These results may indicate that less function of the pain descending inhibitory system in patients with OA is correlated with higher activity-related pain (WOMAC), less balance, and cortical plasticity especially with increased low-frequency (delta) brain oscillations. These associations seem modified by race.
Neurophysiological biomarkers of motor improvement from Constraint-Induced Movement Therapy and Robot-Assisted Therapy in participants with stroke
(2023) SIMIS, Marcel; THIBAUT, Aurore; IMAMURA, Marta; BATTISTELLA, Linamara Rizzo; FREGNI, Felipe
BackgroundThe mechanism of stroke recovery is related to the reorganization of cerebral activity that can be enhanced by rehabilitation therapy. Two well established treatments are Robot-Assisted Therapy (RT) and Constraint-Induced Movement Therapy (CIMT), however, it is unknown whether there is a difference in the neuroplastic changes induced by these therapies, and if the modifications are related to motor improvement. Therefore, this study aims to identify neurophysiological biomarkers related to motor improvement of participants with chronic stroke that received RT or CIMT, and to test whether there is a difference in neuronal changes induced by these two therapies.MethodsThis study included participants with chronic stroke that took part in a pilot experiment to compare CIMT vs. RT. Neurophysiological evaluations were performed with electroencephalography (EEG) and transcranial magnetic stimulation (TMS), pre and post rehabilitation therapy. Motor function was measured by the Wolf Motor Function Test (WMFT) and Fugl-Meyer Assessment Upper Limb (FMA-UL).ResultsTwenty-seven participants with chronic stroke completed the present study [mean age of 58.8 years (SD +/- 13.6), mean time since stroke of 18.2 months (SD +/- 9.6)]. We found that changes in motor threshold (MT) and motor evoked potential (MEP) in the lesioned hemisphere have a positive and negative correlation with WMFT improvement, respectively. The absolute change in alpha peak in the unlesioned hemisphere and the absolute change of the alpha ratio (unlesioned/lesioned hemisphere) is negatively correlated with WMFT improvement. The decrease of EEG power ratio (increase in the lesioned hemisphere and decrease in the unlesioned hemisphere) for high alpha bandwidths is correlated with better improvement in WMFT. The variable ""type of treatment (RT or CIMT)"" was not significant in the models.ConclusionOur results suggest that distinct treatments (RT and CIMT) have similar neuroplastic mechanisms of recovery. Moreover, motor improvements in participants with chronic stroke are related to decreases of cortical excitability in the lesioned hemisphere measured with TMS. Furthermore, the balance of both EEG power and EEG alpha peak frequency in the lesioned hemisphere is related to motor improvement.
Multiple Criteria Decision Analysis (MCDA) for evaluating cancer treatments in hospitalbased health technology assessment: The Paraconsistent Value Framework
(2022) CAMPOLINA, A. G.; ESTEVEZ-DIZ, M. Del Pilar; ABE, J. M.; SOáREZ, P. C. de
Background In recent years, the potential of multi-criteria decision analysis (MCDA) in the health field has been discussed widely. However, most MCDA methodologies have given little attention to the aggregation of different stakeholder individual perspectives. Objective To illustrate how a paraconsistent theory-based MCDA reusable framework, designed to aid hospital-based Health Technology Assessment (HTA), could be used to aggregate individual expert perspectives when valuing cancer treatments. Methods An MCDA methodological process was adopted based on paraconsistent theory and following ISPOR recommended steps in conducting an MCDA study. A proof-of-concept exercise focusing on identifying and assessing the global value of first-line treatments for metastatic colorectal cancer (mCRC) was conducted to foster the development of the MCDA framework. Results On consultation with hospital-based HTA committee members, 11 perspectives were considered in an expert panel: medical oncology, oncologic surgery, radiotherapy, palliative care, pharmacist, health economist, epidemiologist, public health expert, health media expert, pharmaceutical industry, and patient advocate. The highest weights were assigned to the criteria ""overall survival""(mean 0.22), ""burden of disease""(mean 0.21) and ""adverse events""(mean 0.20), and the lowest weights were given to ""progression-free survival""and ""cost of treatment""(mean 0.18 for both). FOLFIRI and mFlox scored the highest global value score of 0.75, followed by mFOLFOX6 with a global value score of 0.71. mIFL was ranked last with a global value score of 0.62. The paraconsistent analysis (para-analysis) of 6 first-line treatments for mCRC indicated that FOLFIRI and mFlox were the appropriate options for reimbursement in the context of this study. Conclusion The Paraconsistent Value Framework is proposed as a step beyond the current MCDA practices, in order to improve means of dealing with individual expert perspectives in hospital- based HTA of cancer treatments. © 2022 Campolina et al.

Motor event-related synchronization as an inhibitory biomarker of pain severity, sensitivity, and chronicity in patients with knee osteoarthritis
(2022) MARQUES, L. M.; BARBOSA, S. P.; PACHECO-BARRIOS, K.; GONCALVES, F. T.; IMAMURA, M.; BATTISTELLA, L. R.; SIMIS, M.; FREGNI, F.
Objective: The study aimed to examine the clinical and neurophysiological predictors of motor event-related desynchronization (ERD) and synchronization (ERS) in patients with chronic pain due to knee osteoarthritis (KOA). Methods: We performed a cross-sectional analysis of our cohort study (DEFINE cohort), KOA arm, with 71 patients, including demographic, functionality, genetic and neurophysiological measures. ERD/ERS was evaluated during hand motor tasks (motor execution, active and passive observation, and imagery). Multivariate regression models were used to explore predictors of ERD/ERS. Results: Although we found an altered ERD/ERS pattern during motor execution and active observation, the ERS pattern could only be clearly differentiated after passive observation.‘. We found no predictors of ERD (excitatory biomarker). For ERS (inhibitory biomarker), our results showed that the main predictors differ across EEG frequency bands. Considering pain measures, we found that visual analogue scale (VAS, right knee) and chronicity of pain negatively predict low beta and high beta ERS, respectively. Pain threshold was positively correlated with alpha ERS, while 36-Item Short Form Survey (SF-36) emotional domain positively predicted beta ERS. Regarding transcranial magnetic stimulation (TMS) markers, intracortical inhibition (ICF) negatively predicted beta and low beta ERS, and left hemisphere cortical silent period (CSP) negatively predicted low beta ERS. Conclusion: Considering that higher power of ERS indicates a stronger cortical organization and inhibitory drive, our results show that limitation of activities due to emotional factors, lower pain threshold, higher VAS pain, and longer duration of pain are associated with lower ERS power (in alpha and beta frequencies), thus indicating a lower inhibitory drive. In the same direction, a lower inhibitory drive as indicated by higher ERS power is associated with higher ICF amplitude. Although there was a negative association between ERS and CSP, this may indicate that ICF values are adjusting CSP results. Our findings support the idea that a less organized cortical response as indicated by changes to the ERS is associated with higher pain correlates in subjects with KOA. © 2022
Repercussions of the COVID-19 pandemic on health services for people with disabilities: report from rehabilitation professionals
(2023) SILVA, Simone Vieira da; REICHENBERGER, Veronika; VIEIRA, Gislene Inoue; CLEMENTE, Karina Aparecida Padilha; RAMOS, Vinicius Delgado; BRITO, Christina May Moran de
Several healthcare processes, including rehabili-tation, require prompt initiation and cannot be interrupted. Therefore, these processes underwent important adaptations during the COVID-19 pandemic. However, it is not fully known how healthcare facilities adapted their strategies and what the results were. This study investigated how rehabilitation services were affected dur-ing the pandemic and what strategies were em-ployed to maintain the provided services. From June 2020 to February 2021, 17 semi-structured interviews were conducted with healthcare profes-sionals working in rehabilitation services from the Brazilian Unified National Health System (SUS), who work at one of the three levels of care, in the municipalities of Santos and Sao Paulo, state of Sao Paulo, Brazil. The interviews were recorded, transcribed, and analyzed via content analysis. The professionals reported organizational changes in their services, with the initial interruption of appointments and, subsequently, the adoption of new sanitary protocols and the gradual return to in-person and/or remote appointments. Working conditions were directly impacted, as there was a need for staffing, training, increased workloads, as well as physical and mental exhaustion among professionals. The pandemic caused a series of changes in healthcare services, some of which were interrupted due to the suspension of numerous ser-vices and appointments. Some in-person appoint-ments were maintained exclusively for patients who presented a risk of short-term deterioration. Preventive sanitary measures and strategies for continuity of care were adopted.
The effectiveness of phototherapy for surface decontamination against SARS-Cov-2. A systematic review
(2023) OLIVEIRA, Susyane Vieira de; NEVES, Filipe Danilo das; SANTOS, Daniela Carvalho dos; MONTEIRO, Mariana Bernardes Batista; SPANGHERO, Maristela S.; MOTTA, Beatriz Nascimento; OLIVEIRA, Igor Pereira de; RODRIGUES, Maria Fernanda Setubal Destro; FRANCO, Adriana Lino dos Santos; CECATTO, Rebeca Boltes
COVID-19 appeared in December 2019, needing efforts of science. Besides, a range of light therapies (photodynamic therapy, ultraviolet [UV], laser) has shown scientific alternatives to conventional decontamination therapies. Investigating the efficacy of light-based therapies for environment decontamination against SARS-CoV2, a PRISMA systematic review of Phototherapies against SARS-CoV or MERS-CoV species discussing changes in viral RT-PCR was done. After searching MEDLINE/PubMed, EMBASE, and Literatura Latino-Americana e do Caribe em Ciencias da Saude we have found studies about cell cultures irradiation (18), blood components irradiation (10), N95 masks decontamination (03), inanimate surface decontamination (03), aerosols decontamination (03), hospital rooms irradiation (01) with PDT, LED, and UV therapy. The best quality results showed an effective low time and dose UV irradiation for environments and inanimate surfaces without human persons as long as the devices have safety elements dependent on the surfaces, viral charge, humidity, radiant exposure. To interpersonal contamination in humans, PDT or LED therapy seems very promising and are encouraged.

ObjectivesTo prospectively assess health-related quality of life (HRQoL), global functionality, and disability in primary caregivers of surviving children and adolescents after COVID-19. MethodsA longitudinal observational study was carried out on primary caregivers of surviving pediatric post-COVID-19 patients (n = 51) and subjects without COVID-19 (n = 60). EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and 12-question WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) were answered for both groups. The univariate regression analysis was carried out using SPSS (v 20) and significance was established at 5%. ResultsThe median duration between COVID-19 diagnosis in children and adolescents and longitudinal follow-up visits was 4.4 months (0.8-10.7). The median age of children and adolescents caregivers with laboratory-confirmed COVID-19 was similar to primary caregivers of subjects without laboratory-confirmed COVID-19 [43.2 (31.6-60.9) vs. 41.5 (21.6-54.8) years, p = 0.08], as well as similar female sex (p = 1.00), level of schooling (p = 0.11), social assistance program (p = 0.28), family income/month U$ (p = 0.25) and the number of household's members in the residence (p = 0.68). The frequency of slight to extreme problems (level & GE; 2) of the pain/discomfort domain according to EQ-5D-5L score was significantly higher in the former group [74% vs. 52.5%, p = 0.03, OR = 2.57 (1.14-5.96)]. The frequency of disability according to WHODAS 2.0 total score was similar to those without disability and unknown (p = 0.79); however, with a very high disability in both groups (72.5% and 78.3%). Further analysis of primary caregivers of children and adolescents with post-COVID-19 condition (PCC) [n = 12/51 (23%)] compared to those without PCC [n = 39/51(77%)] revealed no differences between demographic data, EQ-5D-5L and WHODAS 2.0 scores in both groups (p > 0.05). ConclusionWe longitudinally demonstrated that pain/discomfort were predominantly reported in approximately 75% of primary caregiver of COVID-19 patients, with high disability in approximately three-quarters of both caregiver groups. These data emphasized the prospective and systematic caregiver burden evaluation relevance of pediatric COVID-19.
Economic analysis of antenatal screening for human T-cell lymphotropic virus type 1 in Brazil: an open access cost-utility model
(2023) ROSADAS, Carolina; SENNA, Katia; COSTA, Milene da; ASSONE, Tatiane; CASSEB, Jorge; NUKUI, Youko; COOK, Lucy; MARIANO, Livia; CASTRO, Bernardo Galvao; GRASSI, Maria Fernanda Rios; OLIVEIRA, Augusto Cesar Penalva de; CATERINO-DE-ARAUJO, Adele; MALIK, Bassit; BOA-SORTE, Ney; PEIXOTO, Paula; PUCCIONI-SOHLER, Marzia; SANTOS, Marisa; TAYLOR, Graham Philip
Background Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus that causes severe diseases, such as aggressive cancer or progressive neurological disease. HTLV-1 affects mainly people in areas with low human development index and can be transmitted from mother to child, primarily through breastfeeding. Refraining from breastfeeding is an effective intervention to reduce the risk of infection in infants. However, HTLV-1 antenatal screening is not offered globally. According to WHO, the scarcity of cost-effectiveness studies is considered one of the major barriers to the implementation of policies to prevent HTLV-1 infection. Therefore, this study aimed to assess the cost-effectiveness of antenatal screening and postnatal interventions to prevent HTLV-1 mother-to-child transmission in Brazil and to develop an open-access, editable, mathematical model that can be used by other countries and regions to assess different scenarios. Methods In this cost-utility analysis, we constructed a decision tree and a Markov model to assess the cost-effectiveness of HTLV-1 antenatal screening and postnatal interventions (ie, avoidance of breastfeeding, by suppression of lactation with cabergoline, and provision of formula feed) to reduce transmission. For our model, we used data from Brazil and we took the perspective of the public health-care system to estimate costs. Findings The implementation of both screening and interventions would result in the prevention of 1039 infections in infants every year in Brazil with an incremental cost-effectiveness ratio (ICER) of US$11 415 per quality-adjusted lifeyear (QALY). 88% of all probabilistic sensitivity analysis simulations had ICER values lower than the Brazilian costeffectiveness threshold ($18 107 center dot 74 per QALY). HTLV-1 prevalence in pregnant women, the risk of HTLV-1 transmission when breastfeeding lasts for 6 months or more, and the cost of screening tests were the variables with the largest effect on ICER. Interpretation HTLV-1 antenatal screening is cost-effective in Brazil. An open-access model was developed, and this tool could be used to assess the cost-effectiveness of such policy globally, favouring the implementation of interventions to prevent HTLV-1 mother-to-child transmission worldwide.
Use of Oral Corticosteroids to Treat HTLV-1-Associated Myelopathy (HAM) in Sao Paulo, Brazil
(2023) DAHY, Flavia Esper; ASSONE, Tatiane; MARCUSSO, Rosa M. N.; MOURA, Joao V. Luisi de; HAZIOT, Michel E. J.; VIDAL, Jose E.; SMID, Jerusa; OLIVEIRA, Augusto C. Penalva de; CASSEB, Jorge
Simple Summary Our findings provide observational evidence supporting oral corticosteroids therapy as maintenance therapy for HTLV-1-associated myelopathy (HAM). The daily use of oral, low-dose prednisone seems to be useful in some subsets of HAM patients and needs to be evaluated in randomized controlled trials. Background: During the development of human T-cell lymphotropic virus (HTLV-1)-associated myelopathy (HAM), the inflammatory phenomenon is very prominent and is a major factor in the outcome of the disease. The use of corticosteroids can modify their natural history, and in this study, we evaluated the effectiveness of using daily low-dose prednisone. Methods: This was a cross-sectional study using data collected by physicians monitoring patients with HAM at the Institute of Infectious Diseases ""Emilio Ribas"", the main referral center for patients with infectious diseases in Sao Paulo, Brazil. The objective was to determine if daily low-dose oral prednisone would be able to stabilize the progression of HAM. The outcome measure was a change in the Osame Motor Disability Score (OMDS). Results: Fifty-four patients used treatment with oral prednisone, 5 milligrams daily. Nine cases were excluded from the study because they did not have at least two rating scales within a minimum interval of one year, and six were excluded for being co-infected with HIV and/or HCV. Thirty-nine patients met this criterion and were included for analysis. The majority were women (71.8%), the mean age was 56.51 years old (SD & PLUSMN; 9.74), and the median time of use of prednisone was 16 months. Thirty-two patients (82.05%) maintained the same OMDS, 5/39 (12.82%) had clinical worsening, and 2/39 (5.13%) improved. Conclusions: There was a trend toward clinical stability with the use of oral corticosteroids. However, randomized controlled trials are necessary to evaluate the use in clinical practices in all stages of HAM.
