title: Older adults with epilepsy: memory complaints and objective neuropsychological performance

description: ABSTRACT Introduction: People with epilepsy frequently complain of poor memory. Objective: To assess the occurrence of memory complaints in older adults with epilepsy (OAE) and whether it is associated with clinical variables, objective cognitive performance, and quality of life (QoL). Methods: The Memory Complaint Questionnaire (MAC-Q) was related to objective cognitive performance, the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), the Quality of Life in Epilepsy Inventory (QOLIE-31), and the clinical characteristics of 83 OAE. Results: OAE showed worse cognitive performance and higher MAC-Q scores when compared to a similar control group (n=40). Impairment in multiple cognitive domains occurred in 34 (41%) OAE and was associated with older age and lower educational level. Memory complaints (MAC-Q≥25) were reported by 45 (54.2%) OAE and associated with older age, lower educational level, onset at ≥60 years, higher NDDI-E scores, lower QOLIE-31 scores, and impairment in multiple cognitive domains. Conclusions: OAE presented worse cognitive performance and greater memory complaints. Episode onset at ≥60 years of age was associated with complaints, but not with objective cognitive deficit. We found an association between subjective and objective cognitive performance, with aspects of epilepsy and worse QoL scores.

title: Beneficial effects of a calf starter versus forage on rumen development and bacteria populations in beef calves

description: ABSTRACT: Rumen development depends on the intake of solid food that is fermented into volatile fatty acids that stimulate the development of the rumen papillae in calves. The starter feeding can promote the growth of papillae in the rumen and as a consequence an earlier weaning. We evaluated the effects of calf starter on ruminal development, and productive response of lactating bull calves raised for meat in the tropics. Twelve male Brahman × Swiss American cross beef calves from a dual-purpose system were randomly assigned two treatments with six animals per treatment: milk-fed calves + Taiwan grass (Pennisetum purpureum, MT) and MT + calf starter, (MTS). Feed intake and growth were measured at 7-day intervals throughout until 210 d of age. At 90 days old, three calves from each treatment were harvested, and fluid and ruminal tissues were collected from the cranial, ventral, dorsal, and dorsal blind ruminal sacs for measurements of many papillaes per cm2 (NP), papillae length (LP) and papillae width (WP). Ruminal bacterial genotype identification was determined by amplicon generation with the Illumina platform. Calf starter-improved weight (Live weight, LW) and average weight gain (ADG) and NP, but, LP and WP was similar in both treatments (p &lt; 0.05). In calves with starter feed treatment, we observed the bacteria Desulfonauticus autotrophicus sp. nov.that was not previously reported in ruminants. Use of calf starter showed benefit for calves with improved feed intake and rumen development because promoted a greater number of rumen papillae.

title: Small vessel occlusion and syphilis in patients with first-ever ischemic stroke

description: ABSTRACT Background: Syphilis is an endemic disease, particularly in low- and middle-income countries, with vascular involvement in large vessels (aortitis), but no clear relationship with stroke patients, except for those who presented with meningovascular neurosyphilis. Objective: To investigate the relationship between a positive history of syphilis determined by serological testing and ischemic stroke etiology, particularly small vessel disease (SVD). Methods: In total, 269 first-ever ischemic stroke patients admitted to the stroke unit were tested for syphilis. Patients with neurosyphilis were excluded. All patients were classified according to the ASCOD phenotyping as SVD — when SVD was the potential causal mechanism (S1) — or non-SVD — when SVD was uncertain (S2), unlike (S3), or not detected (S0). Results: Syphilis was positive in 32 (12%) patients. When comparing patients with positive and negative serology, the only significant difference was SVD as the causal mechanism (S1) in patients with positive results: 9 (28%) vs. 22 (9%), p&lt;0.01. Conclusion: The current study showed that the frequency of positive syphilis serological test was higher in patients with first-ever ischemic stroke and SVD as the potential causal mechanism. This finding could be related to the endothelial dysfunction occurring in syphilis.

title: Parkinson's disease effect on autonomic modulation: an analysis using geometric indices

description: ABSTRACT Background: Parkinson's disease (PD) produces autonomic changes, indicating lower parasympathetic modulation and global variability, but these changes need further studying regarding geometric methods. Objective: To investigate the autonomic modulation in individuals with PD using heart rate variability (HRV) indices obtained through geometric methods. Methods: This is a cross-sectional study that assessed 50 individuals, split into two groups: PD group (PDG; n=26; 75.36±5.21 years) and control group (CG; n=24; 75.36±5.21 years). We evaluated the autonomic modulation by measuring the heart rate beat-to-beat for 30 min with the individual in supine rest using a heart rate monitor and assessed geometric indices (RRtri, TINN, SD1, SD2, SD1/SD2 ratio, and qualitative analysis of the Poincaré plot). Results: Significant reductions were found in RRtri, TINN, SD1, and SD2 indices among PDG compared to CG. Regarding the SD1/SD2 ratio, no significant changes were detected between the groups. The Poincaré plot demonstrated that individuals with PD had lower beat-to-beat dispersion in RR intervals, in addition to greater long-term dispersion of RR intervals compared to CG. Conclusions: The results suggest a reduction in the parasympathetic autonomic modulation and global variability in individuals with PD compared to controls, regardless of sex, age, and body mass index.

title: Impact of COVID-19 pandemic on the sleep quality of medical professionals in Brazil

description: ABSTRACT Introduction: Coronavirus pandemic began in China in 2019 (COVID-19), causing not only public health problems but also great psychological distress, especially for physicians involved in coping with the virus or those of the risk group in social isolation, and this represents a challenge for the psychological resilience in the world population. Studies showed that health professionals had psychological symptoms such as depression, anxiety, insomnia, stress, among others. Objectives: To investigate the quality of sleep and the prevalence rate of sleeping disorders among physicians during COVID-19 pandemic, and identify the psychological and social factors associated with the condition. Methods: A cross-sectional study of an online questionnaire was applied for physicians in Brazil. Among the 332 participants included, 227 were women. Sociodemographic assessment was used in the questionnaire, as well as the scale of impact on the events of modifications caused by COVID-19, assessment on sleep quality (PSQI), presence and severity of insomnia (ISI), depressive symptoms (PHQ-9), and anxiety (GAD-7). Results: Most physicians (65.6%) had changes in sleep. Poor sleep quality was reported by 73.1%, depressive symptoms were present in 75.8%, and anxiety in 73.4%. Conclusion: Our study found that more than 70% of the physicians assessed had impaired sleep quality, characterizing insomnia symptoms during COVID-19 outbreak. Related factors included an environment of isolation, concerns about COVID-19 outbreak and symptoms of anxiety and depression. Special interventions are needed to promote health professionals’ mental well-being and implement changes in this scenario.

title: Validity and reliability of Kessler Psychological Distress Scale for Brazilian elderly: a cross-sectional study

description: ABSTRACT Objective: to verify the validity and reliability of the Psychological Distress Scale for screening mental distress. Methods: a cross-sectional study with 75 elderly people. Psychological Distress scale and Self Reporting Questionnaire were used. Criterion validity was verified using Spearman’s correlation and diagnostic accuracy measures. Cronbach’s alpha coefficient was used to investigate reliability. Results: the total internal consistency of the Psychological Distress Scale was α=0.844. Concurrent validity between this instrument and the Self Reporting Questionnaire was ρ=0.722 (p&lt;0.001). The best cut-off point for screening mental distress among elderly people was a total score greater than 14, with sensitivity equal to 75.47% and specificity equal to 85.0%. Conclusions: the scale was robust for screening mental distress, given its high reliability, in terms of homogeneity, and adequate criterion validity, whose best cut-off point for screening was a score greater than 14.

title: Managing intrathecal administration of nusinersen in adolescents and adults with 5q-spinal muscular atrophy and previous spinal surgery

description: ABSTRACT Background: Spinal muscular atrophy (SMA) is a neurodegenerative disease of lower motor neurons associated with frequent occurrence of spinal deformity. Nusinersen is an antisense oligonucleotide that increases SMN protein level and is administrated by frequent intrathecal lumbar injections. Thus, spinal deformities and previous spinal surgery are important challenges for drug delivery in SMA. Objective: To report imaging methods used for Nusinersen injection in SMA patients. Methods: Nusinersen injection procedures in SMA types 2 and 3 patients who had previous spinal surgery were analyzed retrospectively to describe the imaging and puncture procedures, as well as the occurrence of complications. Results: Nine SMA patients (14 to 50 years old) underwent 57 lumbar punctures for nusinersen injection. Six patients had no interlaminar space available; in five of them, a transforaminal approach was used, and another one underwent a surgery to open a posterior bone window for the injections. Transforaminal puncture was performed using CT scan in three cases and fluoroscopy in the other two, with a similar success rate. One patient in the transforaminal group had post-procedure radiculitis, and another one had vagal reaction (hypotension). In three cases, with preserved interlaminar space, injections were performed by posterior interlaminar puncture, and only one adverse event was reported (post-puncture headache). Conclusion: In SMA patients with previous spinal surgery, the use of imaging-guided intervention is necessary for administering intrathecal nusinersen. Transforaminal technique is indicated in patients for whom the interlaminar space is not available, and injections should always be guided by either CT or fluoroscopy.

title: Impact of rapid eye movement sleep behavior disorder and autonomic disorders on Parkinson's disease: a review

description: ABSTRACT Parkinson's disease (PD) has heterogeneous clinical manifestations and prognoses. It is accompanied by a group of motor and non-motor symptoms ranging from independence to total disability, limiting work and personal care activities. Currently, disease subtype markers for informing prognosis remain elusive. However, some studies have reported an association between rapid eye movement (REM) sleep behavior disorder (RBD) and faster motor and non-motor symptom progression, including autonomic dysfunction and cognitive decline. Moreover, since autonomic dysfunction has been described in idiopathic forms of RBD, and they share some central regulatory pathways, it remains unclear whether they have a primary association or if they are more severe in patients with PD and RBD, and thus are a disease subtype marker. This article aimed at critically reviewing the literature on the controversies about the prevalence of RBD in PD, the higher incidence of PD non-motor symptoms associated with RBD, the evidence of faster motor worsening in parkinsonian patients with this parasomnia, and the main pathophysiological hypotheses that support these findings.
