Abstract
Human T-lymphotropic virus type 1 (HTLV-1) is classically associated with the HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), although the mechanisms of this neurological disorder remain unclear. In addition, some patients who develop "minor" neurological signs that do not meet diagnostic criteria for HAM/TSP are classified as asymptomatic carriers. This study aims to demonstrate the neurological symptoms of Brazilian patients living with HTLV-1 classified as not-HAM.TSP. This observational study evaluated patients treated in an HTLV reference center in Bahia, Brazil, between February 2022 and July 2023. The data were obtained through the analysis of medical records and neurological consultation. Those individuals classified as HAM/ TSP were excluded from this study. 74 patients were submitted to a careful neurological evaluation: 23 HAM/TSP, 22 were classified with intermediate syndrome (IS), and 29 were oligosymptomatic. Self-reported symptoms were significantly more common in the IS group, including urinary symptoms such as nocturia, urgency, incontinence, dysuria, weakness, paresthesia, lumbar pain, xerostomia, and xerophthalmia. Physical examination findings consistent with reduced vibratory and tactile sensitivity were more common in the IS group (p = 0.017 and p = 0.013). Alterations in the V and VIII cranial nerves were present in both groups. HTLV-1 can lead to the development of important neurological signs and symptoms in apparently asymptomatic individuals. This data highlights the need for more research into the neurological aspects of HTLV-1 infection and emphasizes the importance of early diagnosis, treatment, and support for individuals living with this virus.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has become a major health concern worldwide. In that context, the understanding of epidemiological and clinical features associated with the disease and its severity is crucial for the establishment of strategies aimed at disease control and remedy.
AIM To describe epidemiological features, signs, symptoms, and laboratory findings among severely ill COVID-19 patients from an intensive care unit in northeastern Brazil as well as to evaluate predictor factors for disease outcomes.
METHODS This is a prospective single-center study that evaluated 115 patients admitted to the intensive care unit in a northeastern Brazilian hospital.
RESULTS The patients had a median age of 65.60 ± 15.78 years. Dyspnea was the most frequent symptom, affecting 73.9% of the patients, followed by cough (54.7%). Fever was reported in approximately one-third of patients and myalgia in 20.8% of the patients. At least two comorbidities were found in 41.7% of the patients, and hypertension was the most prevalent (57.3%). In addition, having two or more comorbidities was a predictor of mortality, and lower platelet count was positively associated with death. Nausea and vomiting were two symptoms that were predictors of death, and the presence of a cough was a protective factor.
CONCLUSION This is the first report of a negative correlation between cough and death in severely ill severe acute respiratory syndrome coronavirus 2-infected individuals. The associations between comorbidities, advanced age, and low platelet count and the outcomes of the infection were similar to the results of previous studies, highlighting the relevance of these features.

Abstract
Introduction: The interest of the world scientific community for an effective vaccine against Helicobacter pylori infection arises from its high prevalence and association with many diseases. Moreover, with an immunological response that is not always effective for the eradication of the bacteria and an increasing antibiotic resistance in the treatment of this infection, the search for a vaccine and new therapeutic modalities to control this infection is urgent.Areas covered: We bring an overview of the infection worldwide, discussing its prevalence, increasing resistance to antibiotics used in its therapy, in addition to the response of the immune system to the infection registered so far. Moreover, we address the most used antigens and their respective immunological responses expected or registered up to now. Finally, we address the trials and their partial results in development for such vaccines.Expert opinion: Although several studies for the development of an effective vaccine against this pathogen are taking place, many are still in the preclinical phase or even without updated information. In this sense, taking into account the high prevalence and association with important comorbidities, the interest of the pharmaceutical industry in developing an effective vaccine against this pathogen is questioned.

Abstract
OBJECTIVE To compare neurological symptoms and signs in HTLV-1 asymptomatic carriers and HTLV-1 patients with overactive bladder (OB) syndrome. METHODS We studied 102 HTLV-1 positive individuals without HAM/TSP (HTLV-1 associated myelopathy/tropical spastic paraparesis) divided into two groups according to the presence or absence of OB syndrome. Clinical interview, neurological exam and proviral load was performed in all patients. RESULTS AND CONCLUSIONS Individuals with OB were more commonly female (84.3 vs. 60.8% of asymptomatics, p=0.01). The prevalence of neurological complaints was higher in OB group, especially hand or foot numbness and arm or leg weakness. There was no difference between the groups in neurological strength and reflexes. Weakness complaint remained strongly associated with OB in multivariate logistic regression analysis adjusting for sex and age [adjusted odds ratio and 95%CI 3.59 (1.45-8.88) in arms and 6.68 (2.63-16.93) in legs]. Proviral load was also different between the two groups with higher level on OB individuals.
