RESUMEN

Introduction: Chronic pain, nocturnal cramps, and sleep alterations are prevalent symptoms and signals in Charcot-Marie-Tooth disease patients. Sleep and pain are bidirectionally related and physical therapy can improve the binomial sleep and pain/nocturnal cramps. Therefore, we hypothesized that the application of a specific physical therapy program for Charcot-Marie-Tooth disease would improve sleep quality, pain perception, and nocturnal cramps. Material and Methods: A non-randomized controlled study that included 9 Charcot-Marie-Tooth disease patients (intervention group - physical therapy program) and 8 controls (active control group - booklet on sleep hygiene). The intervention lasted 8 weeks, three sessions per week. The effects were evaluated ten days before (baseline) and ten days after the intervention (post). Our primary outcome was sleep quality (subjective and objective, assessed by Pittsburgh sleep quality index and actigraphy, respectively); and secondary outcomes were pain perception (brief pain inventory) and nocturnal cramps (self-report). Results: The program was able to improve the subjective sleep quality (p=0.005) and nocturnal cramps (p<0.001) but had no effect on actigraphy data (p>0.05) neither on pain perception (p>0.05). Conclusion: Our initial hypothesis was partially corroborated: the improvement in subjective quality of sleep and nocturnal cramps is already beneficial for the health promotion of the volunteers in this study affected by the disease. Our findings may serve as a basis for future research to develop a program focused on the treatment of analgesia, which can improve pain perception and alter the objective quality of sleep.

RESUMEN

This study evaluated the presence of oral lesions in patients with COVID-19 hospitalized in an intensive care unit (ICU). Data included demographic, clinical, and laboratory information. Clinical assessment of the oral cavity was performed on the 2 nd and 5 th days of orotracheal intubation. Thirty-eight patients were evaluated and 16 (42.1%) presented oral lesions during their ICU stay. The median age and length of stay were 75 years and 15 days, respectively. Among the patients with oral lesions, ulcerative oral lesions were reported in 14 (87.5%) patients, of which 11 (78.6%) were found on the lips. This study highlights the importance of oral examination for patients admitted to the ICU with COVID-19.

RESUMEN

Introduction: Charcot-Marie-Tooth disease is an inherited neuropathy that presents two main forms - type 1 and type 2 -, differentiated by the speed of the nervous conduction. Our goal was to assess sleep in Charcot-Marie-Tooth disease and its relationship with pain perception and nocturnal cramps. Material and Methods: This was a case-control study. The case group was composed of 10 volunteers diagnosed with the type 1 and 23 with the type 2. The control group was composed of 22 individuals from the same family matched by age and gender. Volunteers underwent clinical screening to assess the presence of nocturnal cramps and filled the brief pain inventory, the Chalder fatigue scale, the Epworth sleepiness scale, and the Pittsburgh sleep quality index. Sleep was evaluated by actigraphy. Results: Type 2 patients presented a more severe perception of pain and fatigue, more time spend awake after sleep onset, and had lower sleep efficiency. The individuals who reported nocturnal cramps also had worse perception of pain, reduced sleep latency, and increased sleep fragmentation. Conclusion: The Charcot-Marie-Tooth type 2 was related with worse sleep quality, perception of pain, and fatigue and these parameters were negatively related.

RESUMEN

We investigated the seroprevalence of SARS-CoV-2 antibodies in individuals working in radio and television stations (TV) in Sergipe state, Northeast Brazil. This cross-sectional study was conducted from December 1 to December 20, 2020, a period which was considered as the beginning of the second wave of COVID-19 in the state. One hundred and thirteen professionals from the three largest media companies in the state were included in this study. Venous blood was collected using venipuncture and a fluorescence immunoassay for qualitative detection and differentiation of IgM and IgG antibodies against SARS-CoV-2 was performed. Twenty-eight media workers had detectable levels of SARS-CoV-2 antibodies (11 IgM+, 6 IgM+/ IgG+, and 11 IgG+) and the estimated seroprevalence was 24.8 % (95 % CI 17.7 - 33.5). Our findings showed a high seroprevalence of SARS-CoV-2 antibodies in radio and TV workers during the second wave of COVID-19 in Brazil.

RESUMEN

BACKGROUND AND PURPOSE: Miller Fisher syndrome (MFS) is a subtype of Guillain-Barré syndrome characterized by the triad of ophthalmoparesis, areflexia, and ataxia. Although cases of MFS have been associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, no studies have synthesized the clinical characteristics of patients with this condition. METHODS: In this rapid systematic review, we searched the PubMed database to identify studies on MFS associated with SARS-CoV-2 infection. RESULTS: This review identified 11 cases, of whom 3 were hospitalized with motor and/or sensory polyneuropathy as the first sign of SARS-CoV-2 infection. SARS-CoV-2 RNA was not detected in analyses of cerebrospinal fluid, suggesting a mechanism of immune-mediated injury rather than direct viral neurotropism. However, antiganglioside antibodies were found in only two of the nine patients tested. It is possible that target antigens other than gangliosides are involved in MFS associated with SARS-CoV-2 infection. CONCLUSIONS: The present patients exhibited clinical improvement after being treated with intravenous immunoglobulin. Although rare, patients with SARS-CoV-2 infection may present neurological symptoms suggestive of MFS. Early recognition of the MFS clinical triad is essential for the timely initiation of treatment.

RESUMEN

The pathophysiological process of the disease, Covid-19, is mediated by innate immunity, with the presence of macrophages responsible for secreting type 1 and 6 interleukins (IL), tumor necrosis factor (TNF) leading to dilation of endothelial cells with a consequent increase in capillary permeability. The treatment of this disease has been much discussed, but the variability in the clinical picture, the difficulties for diagnosis and treatment, especially of those patients who have the most severe clinical condition of the disease. Immunization is an effective tool for controlling the spread and overload of health services, but its effectiveness involves high investments in the acquisition of inputs, development of vaccines, and logistics of storage and distribution. These factors can be obstacles for countries with lower economic, technological, and infrastructure indexes. Reflecting on these difficulties, we raised the possibility of adjuvant therapies with imminent research feasibility, as is the case with the use of carvacrol, a monoterpenic phenol whose has biological properties that serve as a barrier to processes mediated by free radicals, such as irritation and inflammation, due to its antioxidant action. Many authors highlighted the activity of carvacrol as a potent suppressor of COX-2 expression minimizing the acute inflammatory process, decreasing the release of some pro-inflammatory mediators such as IL-1ß, TNF-α, PGE2. Anyway, the benefits of carvacrol are numerous and the therapeutic possibilities too. With this description, the question arises: would carvacrol be a supporting treatment option, effective in minimizing the deleterious effects of Covid-19? There is still a lot to discover and research.

RESUMEN

The coronavirus disease 2019 (COVID-19) outbreak has created unprecedent challenges for healthcare systems worldwide. Oncology services have been reorganized to decrease the risk of nosocomial acquisition of SARS-CoV-2, but changes in treatment pathways and follow-up cancer care can result in patients receiving suboptimal or delayed care. Herein, we describe a cross-sectional nested cohort study conducted to evaluate delays in care for patients with head and neck cancer (HNC) in post-treatment follow-up or palliative care during the COVID-19 pandemic in Northeast Brazil and its impact on health outcomes. Information was extracted from medical records and supplemented by telephone interviews. We compared the following health outcomes: self-perception of anxiety or sadness, fear of COVID-19 infection, cancer-related complications during social isolation, self-medication, diagnosis of COVID-19, and death between patients with and without delayed cancer care. The Mann-Whitney U test was used to compare distributions of continuous variables and the Fisher exact test was used for categorical variables. Thirty-one HNC patients were included in the study, and no case of confirmed SARS-CoV-2 was found. Delayed cancer care due to restriction in health services was reported in 58.1% of cases, and there was no report of telemedicine use during the COVID-19 outbreak. Cancer-related complications during the COVID-19 pandemic were described for most patients (67.7%) and included pain or discomfort, swelling, and dyspnea. Eight (25.8%) patients reported use of prescribed morphine or codeine to manage pain and six (19.4%) patients reported self-medication with over-the-counter (OTC) non-steroidal anti-inflammatory drugs (NSAIDs). We found an association between delayed HNC care and the use of self-medication (p = 0.028). This study indicated that patients with delayed HNC care during the COVID-19 outbreak are more likely to use self-medication with NSAIDs for pain management. Better strategies to follow HNC patients in socioeconomically disadvantaged communities need to be discussed and implemented.

RESUMEN

PURPOSE: To evaluate the safety and potential healing efficacy of the topical ocular administration of a gelatin membrane containing usnic acid/liposomes (UALs) for corneal cicatrization. UALs have shown healing activity in animal models of dermal burn lesions. We evaluated the safety of topical ocular administration of UAL and its potential healing efficacy as an ophthalmic treatment on chemical lesions in rabbit eyes. METHOD: The Draize test was used to check for ocular toxicity and the score was zero at each observation, indicating the ocular safety of a gelatin membrane containing usnic acid/liposome. Its potential healing efficacy as an ophthalmic treatment on chemical lesions in rabbit eyes was also assessed. RESULTS: After epithelial removal and treatment with UAL, there was a 49.4 % reduction in injury under in vivo conditions compared with a 36.6 % reduction in the control, a gelatin membrane containing liposome without usnic acid. Histological analysis of ocular surface chemical injury-tissue sections after treatment with UAL supported these observations. The corneal expression of VEGF and TGF-ß1increased by 70 % and 50 % respectively following treatment with UAL gelatin membrane. CONCLUSION: These results indicate the potential therapeutic application of UAL gelatin membranes as an ophthalmic treatment that may be used for corneal cicatrization.

RESUMEN

Myrtenol has gained wide interest because of its pharmacological profiles, mainly for treatment of chronic diseases. To improve the solubility of myrtenol, the formation of inclusion complexes with ß-cyclodextrin was performed by physical mixture, kneading process or slurry complexation (SC) methods and characterized using thermal analysis, XRD, SEM and NMR. From these results, myrtenol complexed by SC was successfully complexed into ß-cyclodextrin cavity. The interaction between myrtenol and ß-cyclodextrin was confirmed by molecular docking. Hence, the SC ß-cyclodextrin-myrtenol complex was evaluate for its anti-hyperalgesic, anxiolytic and antioxidant activity in a fibromyalgia model. Results show that myrtenol and ß-cyclodextrin form a stable complex and have anti-hyperalgesic effect, improve the cognitive impairment caused and have an anxiolytic-like effect. Furthermore, the ß-cyclodextrin/myrtenol complex decrease lipoperoxidation, increased catalase activity and a reduce SOD/CAT ratio. Therefore, ß-cyclodextrin/myrtenol complex reduce painful behavior, improves motor skills and emotional behavior and decreases oxidative stress in a fibromyalgia model.

RESUMEN

Carvacrol is a monoterpene present in the essential oil of a number of plants and has been widely used in traditional medicine because it is considered to have a range of therapeutic effects including in relation to respiratory disease. To conduct a systematic review and meta-analysis to assess the anti-inflammatory and antioxidant activities of carvacrol when used in the treatment of respiratory disorders. A comprehensive literature search using Scopus, MEDLINE-PubMed, Cochrane and Web of Science was undertaken. Papers related to the anti-inflammatory or antioxidant properties of carvacrol in the treatment of an injury in the respiratory system in in vivo studies and published in the period up to and including August 2019. A total of 152 studies were initially identified, with only 17 meeting the inclusion criteria. Five of the studies were performed in humans, and 12 were performed in rodents. Among the 17 studies included in the systematic review, we performed the meta-analysis with nine of the studies with animals. Carvacrol had a positive effect on the reduction of interleukin (IL)-1ß, IL-4, IL-8 and malondialdehyde (MDA); however, the analysis indicated that carvacrol had no effect on IL-6 and tumor necrosis factor alpha (TNF-α), probably due to the methodological quality of the studies and their heterogeneity. Current evidence supports the antioxidant and anti-inflammatory effects of carvacrol, but its relationship with the reduction of some inflammatory mediators in animals with lung injury needs further elucidation.

RESUMEN

BACKGROUND: Physiotherapeutic rehabilitation is essential to improve functional mobility, muscular strength, balance and quality of life of stroke patients, but conventional techniques using repeated physical activities can soon become monotonous. The use of virtual reality (VR) in rehabilitation offers a possible alternative to the traditional methods of promoting improvements in muscle strength and balance. However, there is not yet consensus about which instruments should be used to assess the effectiveness of VR in stroke rehabilitation. OBJECTIVE: To conduct a systematic review to identify the types of evaluation tools used for different VR interventions to rehabilitate stroke patients, considering balance, strength, function, quality of life, cognition and motivation. DATA SOURCES: A comprehensive literature search using MEDLINE-PubMed, Web of Science, Scopus, Lilacs and IEEE Xplore was undertaken. STUDY SELECTION: Studies on stroke patients who had undergone VR therapy and an assessment of its effectiveness using evaluative instruments. STUDY APPRAISAL AND SYNTHESIS METHODS: Data were extracted by a single reviewer using standardised forms, and were checked by a second reviewer. The extracted information included study design, number of participants, type of stroke, items that were evaluated (balance, muscle strength, functional evaluation), console used, number of rehabilitation sessions, results and conclusions. RESULTS: In total, 1836 articles were identified; of these, 29 were included in this review after consideration of the inclusion and exclusion criteria. The selected articles rated one or more of the following factors: balance (n=12), grip strength (with or without devices for direct measurement) (n=8), functionality (n=12) and quality of life (n=12). LIMITATIONS: The full text of one article was not available, despite a request to the authors to send it via email. CONCLUSION AND IMPLICATIONS OF KEY FINDINGS: The Berg Balance Scale, the Fugl-Meyer Assessment and the Stroke Impact Scale were the instruments used most frequently to assess balance, function and quality of life, respectively, in stroke patients who underwent rehabilitation using VR. Systematic review registration PROSPERO number: 87546.

RESUMEN

Some recent studies have shown that pirfenidone (PFD) has favorable results in the healing process of the cornea. However, PFD in solution exhibits short half-life after topical application, and in this context, a liquid crystal nanoparticle system containing PFD (PFD-LCNPs) was developed. The nanoparticles were characterized by transmission electron microscopy, atomic force microscopy, small angle X-ray diffraction and polarized light microscopy. The PFD-LCNPs had particle size and zeta potential of 247.3 nm and -33.60 mV (stores at 4 °C), respectively, and 257.5 nm and -46.00 mV (stored at 25 °C), respectively. The pH of the formulation was 6.9 and the encapsulation efficiency was 35.9%. The in vitro release profiles indicated that PFD sustained release from PFD-LCNPs for up to 12 h. In vitro study of ocular irritation (HET-CAM test) concluded that components of the formulation are well tolerated for ocular administration. Corneal re-epithelialization time after chemical burning was significantly reduced in rabbits treated with PFD-loaded LCNPs when compared to the group treated with a vehicle. In addition, the anti-inflammatory action of pirfenidone was observed by reducing myeloperoxidase activity (MPO) and inflammatory cells in the histology of the tissues of animals treated with PFD-LCNPs. These findings indicated that the PFD-LCNPs might have the potential for effective ocular drug delivery.

RESUMEN

Bacterial keratitis is an ocular infection that can lead to severe visual disability. Staphylococcus aureus is a major pathogen of the eye. We recently demonstrated the strong antimicrobial activity of LyeTxI-b, a synthetic peptide derived from a Lycosa erithrognatha toxin. Herein, we evaluated a topical formulation (eye drops) containing LyeTxI-b to treat resistant bacterial keratitis. Keratitis was induced with intrastromal injection of 4 × 105 cells (4 µL) in New Zealand female white rabbits. Minimum inhibitory concentration (MIC) and biofilm viability were determined. LyeTxI-b ocular toxicity was evaluated through chorioallantoic membrane and Draize tests. One drop of the formulation (LyeTxI-b 28.9 µmol/L +0.5% CMC in 0.9% NaCl) was instilled into each eye four times a day, for a week. Slit-lamp biomicroscopy analysis, corneal histopathological studies and cellular infiltrate quantification through myeloperoxidase (MPO) and N-acetylglucosaminidase (NAG) detection were performed. LyeTxI-b was very effective in the treatment of keratitis, with no signs of ocular toxicity. Planktonic bacteria MIC was 3.6 µmol/L and LyeTxI-b treatment reduced biofilm viability in 90%. LyeTxI-b eliminated bacteria and reduced inflammatory cellular activity in the eyes. Healthy and treated animals showed similar NAG and MPO levels.

RESUMEN

Carvacrol has a high therapeutic potential, with in vitro studies showing promising results in different cellular models using a variety of methodological designs. Therefore, the objective of this study was to conduct a systematic review to analyze the pharmacological effects of carvacrol in in vitro studies. A comprehensive search of the literature was made using four databases: Science Direct, Scopus, MEDLINE-PubMed, and Web of Science using different combinations of the following keywords: carvacrol, drug therapy, therapeutic uses, in vitro study. The search of the databases was for studies conducted in the period up to and including September 2016. A total of 3,269 studies were initially identified, with only 31 meeting the inclusion criteria. The included studies contained a variety of in vitro models able to determine the properties of Carvacrol. The following properties of Carvacrol were identified: antimicrobial (7 studies), bactericidal (4), bactericidal and antifungal (1), antiinflammatory (4), anticancer (4), mutagenic (4), antioxidant (3), antifungal (3), antidepressant (1), as a modulator of nerve impulses (1) and an immunological modulator (1). The In vitro studies with Carvacrol included in this review showed a diversity of models and confirmed the therapeutic potential of this product in relation to several diseases.

RESUMEN

PURPOSE: Report a case series study of individuals who, after having a suspected arboviral disease during an epidemic outbreak in north-eastern Brazil, presented symptoms of acroparesthesia. METHODS: A retrospective evaluation of patients with acroparesthesia undertaken between December 2015 and October 2016 following a clinical picture suggestive of an arboviral infection. RESULTS: Clinical and electrophysiological data were obtained from 29 individuals. 13% were male. All presented a main complaint of numbness in the hands, with 86% presenting bilateral symptoms. The symptoms started within 60 days of the clinical picture in 62% of cases. The electrophysiological study demonstrated CTS in 54 median nerves. It was classified as mild in 24.1% of cases, moderate in 32.7%, severe in 24.1%, very severe in 6.8% and extremely severe in 5.1%. CONCLUSION: The best explanation for the presence of acroparesthesia following an arboviral infection may be the narrowing of the carpal tunnel caused by the inflammatory joint process usually observed in cases of chikungunya infection. CLINICAL RELEVANCE: This is the first study with electrophysiological data that associates arboviral infection with CTS.

RESUMEN

BACKGROUND: Charcot-Marie-Tooth (CMT) disease is part of a group of genetically determined neuropathies. The intrinsic muscles of the feet and legs are affected early in the disease, impacting balance and mobility. RESEARCH QUESTION: The purpose of this study was to evaluate individuals with type 2 Charcot-Marie-Tooth disease to understand how motor changes interfere in balance and function. METHODS: The sample comprised 15 individuals with CMT2 from the same family (CMT2G) and a control group (CG) of healthy individuals matched for age and gender. The CMT individuals were classified using the Charcot-Marie-Tooth Neuropathy Score (CMTNS). Muscle strength of the ankle was assessed using a manual dynamometer. Balance was measured using a stabilometer and Berg's Balance Scale (BBS). Functional performance was measured by the Timed Up and Go Test (TUG). RESULTS: There was a statistically significant difference between the CMT2G and the CG for right side (RS) and left side (LS) muscle strength (dorsiflexors-RS and LS: p < 0,0001; invertors-RS and LS: p < 0.0001; plantarflexors-RS: p < 0.0001; plantarflexors-LS: p = 0.0019; evertors-RS: p = 0.0016; evertors-LS: p<0.0001) in the parameters for the velocity and displacement of center of pressure (CoP) anterior-posterior (AP) in the stabilometry tests with eyes open (EO) and closed (EC) (VCoPAP-EO and VCoPAP-EC: p = 0.0123; DCoPAP-OE: p = 0.0183 and DCoPAP-EC: p = 0.0129), the Berg Balance Scale (p = 0.0066) and the TUG test (p = 0.0003). SIGNIFICANCE: Thus when the severity of the disease is mild the instability is caused by the weakness of the dorsiflexors and plantarflexors. In patients considered moderate/severe, in addition to weakness of the leg muscles, loss of proprioception will contribute to impaired balance.
