RESUMO

Procedures such as transport and marketing can subject animals to water and feed deprivation and impair animal health and performance. Maintaining the mineral status of animals under these conditions can bring benefits to health and performance. The use of hydroxychloride mineral sources can improve mineral status, nutrient digestibility and performance. Two studies were conducted to investigate how the supplementation of 02 trace mineral sources of Cu and Zn and 48-hour water/feed deprivation would affect the performance and metabolism of grass-fed beef cattle. In the first study, 20 castrated and rumen-canulated Nellore steers (BW = 350 ±â€¯132 kg; 20 m) were distributed in individual pens, in a 2 × 2 factorial arrangement: supplemental Cu and Zn sources from inorganic vs hydroxychloride (HTM) and 48-hours deprivation (WFD) vs unrestricted (WFU) access to water and feed. The 57d of study was divided into two periods: (1) Adaptation from -21d to -1d and (2) evaluation from 0d to 36d. Interaction between deprivation × period was detected (P < 0.05) for digestibility of DM (DMD), organic matter (OMD), neutral detergent fiber (NDFD), and acid detergent fiber (ADFD). Deprivation increased DMD, OMD, NDFD, and ADFD immediately after the deprivation period (3-5d), but impaired digestibility at longer periods such as 11-13d and 32-34d. DM (DMI) and nutrient intake (P = 0.075), as well as NDFD were higher in HTM. Several ruminal parameters were affected by deprivation: short-chain fatty acids concentration decreased, while rumen pH increased (deprivation × time; P < 0.05); decreased propionate, butyrate and increased isobutyrate, isovalerate, and valerate in WFD (deprivation × time; P < 0.05), respectively. In the second study, eighty-four intact Nellore males (BW = 260 ±â€¯35 kg) were blocked by BW and randomly assigned to Urochloa brizantha cv. Marandu paddocks for 131d in a 2 × 2 factorial arrangement. Liver Cu was higher in WFU/HTM animals (mineral × deprivation; P < 0.05). Interaction between deprivation × period (P < 0.05) was detected for BW and average daily gain (ADG). On 2d and 12d after deprivation, WFD increased ADG and recovered the BW lost. In conclusion, water and feed deprivation imposed in these trials were able to impact several nutrient digestibility and ruminal fermentation parameters in short- and long-term. Performance was not affected by the studied factors. Furthermore, supplementation with sources of Cu and Zn hydroxychloride increased Cu in the liver and tended to increase DMI and NDFD.

RESUMO

Systemic autoimmune myopathies (SAMs) are rare diseases that lead to muscle inflammation and may be associated with a variety of systemic manifestations. Although there is great heterogeneity in the spectrum of extra-muscular involvement in SAMs, interstitial lung disease (ILD) is the most frequent lung manifestation. SAM-related ILD (SAM-ILD) presents significant variations according to geographic location and temporal trends and is associated with increased morbidity and mortality. Several myositis autoantibodies have been discovered over the last decades, including antibodies targeting aminoacyl-tRNA synthetase enzymes, which are associated with a variable risk of developing ILD and a myriad of other clinical features. In this review, the most relevant topics regarding clinical manifestations, risk factors, diagnostic tests, autoantibodies, treatment, and prognosis of SAM-ILD are highlighted. We searched PubMed for relevant articles published in English, Portuguese, or Spanish from January 2002 to September 2022. The most common SAM-ILD patterns are nonspecific interstitial pneumonia and organizing pneumonia. The combination of clinical, functional, laboratory, and tomographic features is usually sufficient for diagnostic confirmation, without the need for additional invasive methods. Glucocorticoids remain the first-line treatment for SAM-ILD, although other traditional immunosuppressants, such as azathioprine, mycophenolate, and cyclophosphamide have demonstrated some efficacy and, therefore, have an important role as steroid-sparing agents.

RESUMO

With an increasing number of international journeys occurring daily, there is also an increase in the need for appropriate medical advice for patients who will undertake such travel. In this context, the lupus patient presents a great challenge to the rheumatologist. However, the demand for such information by patients is low, and it has proven difficult for the medical community to adequately provide it. In this article, we carried out a literature review of the medical recommendations made for the lupus patient in order to guide the rheumatologist through the topic of travel medicine.

RESUMO

Hearing aids (HAs) are an effective strategy for auditory rehabilitation in patients with peripheral hearing deficits. Yet, the neurophysiological mechanisms behind HA use are still unclear. Thus far, most studies have focused on changes in the auditory system, although it is expected that hearing deficits affect a number of cognitive systems, notably speech. In the present study, we used audiometric evaluations in 14 patients with bilateral hearing loss before and after one year of continuous HA use and functional magnetic resonance imaging (fMRI) and cortical thickness analysis in 12 and 10 of them compared with a normal hearing control group. Prior to HA fitting, fMRI activity was found reduced in the auditory and language systems and increased in visual and frontal areas, expanding to multimodal integration cortices, such as the superior temporal gyrus, intraparietal sulcus, and insula. One year after rehabilitation with HA, significant audiometric improvement was observed, especially in free-field Speech Reception Threshold (SRT) test and functional gain, a measure of HA efficiency. HA use increased fMRI activity in the auditory and language cortices and multimodal integration areas. Individual fMRI signal changes from all these areas were positively correlated with individual SRT changes. Before rehabilitation, cortical thickness was increased in parts of the prefrontal cortex, precuneus, fusiform gyrus, and middle temporal gyrus. It was reduced in the insula, supramarginal gyrus, medial temporal gyrus, occipital cortex, posterior cingulate cortex, and claustrum. After HA use, increased cortical thickness was observed in multimodal integration regions, particularly the very caudal end of the superior temporal sulcus, the angular gyrus, and the inferior parietal gyrus/superior temporal gyrus/insula. Our data provide the first evidence that one year of HA use is related to functional and anatomical brain changes, notably in auditory and language systems, extending to multimodal cortices.

RESUMO

Paraguay has registered no human cases of rabies since 2004, and the last case in dogs, reported in 2009, was due to a variant maintained in the common vampire bat "Desmodus rotundus". In 2014, a dog was diagnosed as positive for rabies with aggression towards a boy and all required measures of control were successfully adopted. Epidemiological investigation revealed that the dog was not vaccinated and had been attacked by a crab-eating fox, "zorro" (Cerdocyon thous). The sample was diagnosed by the Official Veterinary Service of the Country and sent to the Center on Rabies Research from the University of São Paulo, Brazil, for antigenic and genetic characterization. A second sample from a dog positive for rabies in the same region in 2015 and 11 samples from a rabies outbreak from Asuncion in 1996 were also characterized. The antigenic profile of the samples, AgV2, was compatible with one of the variants maintained by dogs in Latin America. In genetic characterization, the samples segregated in the canine (domestic and wild species)-related group in an independent subgroup that also included samples from Argentina. These results and the epidemiology of the case indicate that even with the control of rabies in domestic animals, the virus can still circulate in wildlife and may be transmitted to domestic animals and humans, demonstrating the importance of continuous and improved surveillance and control of rabies, including in wild species, to prevent outbreaks in controlled areas.

RESUMO

Any of the various layers of the eye may suffer injury in systemic lupus erythematosus, ranging from keratoconjunctivitis sicca to retinopathy and optic neuritis. Rheumatologists must always be aware of ocular involvement in those patients since rapid diagnosis and a prompt intervention in those severe cases can prevent visual loss or even irreversible blindness. We present here the case of a 14-year-old girl who, despite a short period of disease, developed chorioretinopathy with transitory visual impairment with a good treatment response.

RESUMO

Despite reports of apparent benefits, social and political pressure beginning in the late 1960s effectively banned scientific inquiry into psychedelic substances. Covert examination of psychedelics persisted through the 1990s; the turn of the century and especially the past 10 years, however, has seen a resurgent interest in psychedelic substances (eg, LSD, ayahuasca, psilocybin). This chapter outlines relevant EEG and brain imaging studies evaluating the effects of psychedelics on the brain. This chapter also reviews evidence of the use of psychedelics as adjunct therapy for a number of psychiatric and addictive disorders. In particular, psychedelics appear to have efficacy in treating depression and alcohol-use disorders.

RESUMO

Rabies is an endemic disease in Brazil, where it is considered a serious public health problem. Although the number of human and dog-transmitted cases has declined in recent decades, rabies in wildlife has emerged considerably. Among the sylvatic animals, wild canids have been considered important hosts of the rabies virus. We performed a retrospective study of reported cases of rabies in wild canids and human victims in Ceará state (Northeast Brazil) during 2003 to 2013. Information was provided by governmental laboratories involved in rabies detection and by the Ministry of Health. From January 2003 to December 2013, a total of 11 931 animal samples were examined for rabies. Positivity were detected in 438 samples (3.67%), of which 229 (52.28%) were domestic animals, 105 (23.97%) wild canids and 104 (23.74%) other wild animals (bats, marmosets and raccoons). Approximately 33% of wild canids surveyed (n = 317) were positive for rabies. During the studied period, a total of 1923 attacks on humans by wild canids were registered. Males (n = 1405) were more affected than females (n = 520; 72.98% versus 27.01%), and the median age of all cases was 36.5 years. Injuries to individuals up to 19 years old corresponded to approximately 30% (n = 565) of all cases. Most of the victims lived in rural areas (72.46%; n = 1395), and the majority showed bites (81.13%; n = 1677) or scratches (12.23%; n = 253). Injuries were considered profound (52.1%; n = 1003), superficial (40.91; n = 788) or multiple with severe laceration (6.98%; n = 134). Only 1300 (67.53%) victims were enrolled for the complete rabies post-exposure prophylaxis scheme. Data from the present study confirm that wild canids are important hosts of rabies virus in northeastern Brazil and jeopardize rabies control in this area. Local authorities should focus their efforts in education of health professionals. In addition, strategies should be formulated to preserve wildlife.

RESUMO

OBJECTIVES: To assess ovarian reserve markers and anti-corpus luteum antibodies (anti-CoL) in adult patients with childhood-onset systemic lupus erythematosus (c-SLE). METHOD: Fifty-seven adult c-SLE female patients and 21 healthy controls were evaluated for anti-CoL. Ovarian reserve was assessed by: follicle stimulating hormone (FSH), luteinizing hormone (LH), oestradiol, anti-Müllerian hormone (AMH), and antral follicle count (AFC). Demographic data, menstrual abnormalities, disease activity, damage, and treatment were also analysed. RESULTS: The median current age was similar in adult c-SLE patients and controls (27.7 vs. 27.7 years, p = 0.414). The medians of AMH (1.1 vs. 1.5 ng/mL, p = 0.037) and AFC (6 vs. 16, p < 0.001) were significantly reduced in SLE patients compared to controls without significant menstrual abnormalities. Anti-CoL were solely observed in c-SLE patients (16% vs. 0%, p = 0.103) and were not associated with demographic data, ovarian reserve parameters, disease activity/damage, and treatment. Further evaluation of c-SLE patients treated with cyclophosphamide revealed a higher median of FSH levels compared to c-SLE patients not treated with cyclophosphamide and controls (8.8 vs. 5.7 vs. 5.6 IU/L, p = 0.032) and lower median AMH (0.4 vs. 1.5 vs. 1.5 ng/mL, p = 0.004) and AFC (4.0 vs. 6.5 vs. 16 IU/L, p = 0.001) levels. Nineteen patients treated exclusively with methotrexate demonstrated a negative correlation between the cumulative dose and AMH levels (p = 0.027, r = -0.507). CONCLUSIONS: The present study demonstrated for the first time that a high cumulative methotrexate dose is a possible cause of subclinical ovarian dysfunction in adult c-SLE patients. Further studies are required to confirm this deleterious effect in other rheumatic diseases, particularly juvenile idiopathic arthritis and idiopathic inflammatory myopathy.

RESUMO

OBJECTIVE: The objective of this paper is to evaluate ovarian reserve in primary antiphospholipid syndrome (PAPS) women and the association between ovarian reserve tests and clinical and laboratorial parameters, and anti-corpus luteum antibody (anti-CoL). METHODS: We screened 85 female patients between 18 to 40 years old with APS. Of these, 67 patients were excluded because of association with other autoimmune diseases (n = 42), contraindication or unwillingness to stop hormonal contraceptive (n = 21), current pregnancy or breastfeeding (n = 3) and previous ovarian surgery (n = 1). Therefore, a cross-sectional study was conducted in 18 PAPS patients and 24 healthy women. They were evaluated at early follicular phase with measurement of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and anti-Müllerian hormone (AMH) and sonographic antral follicle count (AFC). Serum measurement of anti-CoL was determined by immunoblot analysis. All analyses were performed after at least six months from the last intake of hormonal contraceptive and resumption of menstruation. RESULTS: The mean age was comparable in PAPS and controls (33.0 ± 5.0 vs. 30.4 ± 7.0 years; p = 0.19). Regarding ovarian reserve tests, the frequencies of low AFC (≤10) (56% vs. 22%, p = 0.04) and very low AFC (≤5) (37% vs. 9%, p = 0.04) were significantly higher in PAPS patients than controls. Trends of higher frequencies of reduced (<1.0 ng/ml), low (<0.5 ng/ml) and negligible (<0.2 ng/ml) AMH levels were found in PAPS patients (p = 0.08, p = 0.07 and p = 0.07, respectively). FSH, LH and estradiol were similar in patients and controls. There was no association between low ovarian reserve and specific types of antiphospholipid antibodies. Anti-CoL was solely observed in PAPS patients (11% vs. 0%; p = 0.177) and was not related to ovarian reserve tests. CONCLUSION: Women suffering from PAPS possessed reduced ovarian reserve, with prevalence greater than 50%.

RESUMO

Primary ovarian insufficiency (POI) is defined as sustained amenorrhea, increased follicle-stimulating hormone and low estrogen levels, whereas diminished ovarian reserve (DOR) is characterized as regular menses and alterations of ovarian reserve tests. POI of autoimmune origin may be associated with adrenal autoimmunity, non-adrenal autoimmunity or isolated. This autoimmune disease is characterized by serum ovarian, adrenocortical or steroidogenic cell autoantibodies. POI of adrenal autoimmune origin is the most frequent type observed in 60-80% of patients. Clinically, amenorrhea is the hallmark of POI, however before menstruation stops completely, irregular cycles occur. Infertility, hot flushes, vaginal atrophy, and dyspareunia are also common. Autoimmune oophoritis is characterized by mononuclear inflammatory cell infiltrate in the theca cells of growing follicles, with early stage follicles without lymphocytic infiltration. This infiltrate includes plasma, B and T-cells. A novel classification criterion for autoimmune POI/DOR is proposed subdividing in three distinct categories (possible, probable and confirmed) according to autoantibodies, autoimmune disease and ovarian histology. Unfortunately, up to date guidelines for the treatment of autoimmune oophoritis are not available. Strategies to POI treatment include hormone replacement and infertility therapy. Assisted conception with donated oocytes has been proven to achieve pregnancy by intra cytoplasmic sperm injection in POI women.

RESUMO

Epidemiological studies with systemic lupus erythematosus (SLE) patients have been reported worldwide but, until now, a large evaluation had not been performed in Brazil. Therefore, we determined the clinical and immunological features of 888 SLE patients followed at our service from 2008 to 2012. The mean age at SLE onset and the mean disease duration were 29.9 ± 9.5 years old and 14.5 ± 8.4 years, respectively. A predominance of female gender (91.9%) and Caucasian ethnicity (69.9%) were observed. Cumulative mucocutaneous manifestations (90.7%) were most commonly identified (malar rash (83.2%), photosensitivity (76.9%)) followed by articular (87.4%), hematological (44.0%) and renal (36.9%) involvements. Antinuclear antibody was detected in all patients, followed by anti-dsDNA (35.1%), anti-Sm (21.8%) and anti-ribosomal P protein antibodies (19.8%). Additional comparison of clinical and laboratory features between genders revealed that malar rash was observed more in female SLE patients (84.5% vs. 69.4%, p = 0.001). Male lupus patients presented a higher frequency of anti-dsDNA (45.8% vs. 34.2%, p = 0.047) and a trend of more nephritis (47.2% vs. 36.0%, p = 0.059). In conclusion, we identified a high prevalence of mucocutaneous manifestations in this Brazilian SLE cohort compared to other countries, mainly malar rash that was most commonly observed in female patients. Anti-dsDNA and other specific SLE autoantibodies were also identified in a higher frequency, predominantly in the male gender.

RESUMO

Two experiments were conducted to evaluate the influence of vaccination on the acute-phase protein (APP) reaction (Exp. 1 and 2) and measures of performance (Exp. 2) in growing beef calves. In Exp. 1, the APP reaction was assessed in newly weaned steers administered 1 of 3 treatments (n = 8 steers/treatment), consisting of 1) Mannheimia haemolytica vaccine (One Shot; Pfizer Inc., New York, NY), 2) Clostridium vaccine (UltraBac 7; Pfizer, Inc.), or 3) saline-injected control. Blood samples for the evaluation of APP concentrations were collected on d 0, 1, 3, 5, 7, 10, and 14 and steer BW measured on d 0 and 21 relative to treatment administration. Plasma concentrations of haptoglobin (Hp) increased (P < 0.05) in vaccinated but not control calves and reached a peak on d 3 and 5 for steers receiving Mannheimia haemolytica and Clostridium vaccine, respectively. Plasma concentrations of ceruloplasmin (Cp) and fibrinogen (Fb) increased (P < 0.05) in all calves after treatment administration and Fb concentrations were greatest (P < 0.01) in calves receiving Mannheimia haemolytica vaccine on d 3 and 5 compared with the other treatments. There were no treatment effects (P = 0.44) on 21-d steer ADG (0.43 kg/d; SEM = 0.082). In Exp. 2, 23 heifers were randomly assigned to 2 treatments: 1) vaccinated (Mannheimia haemolytica vaccine (One Shot; n = 12) and 2) saline control (n = 11). After vaccination, blood samples were collected for determination of APP concentrations on d 0, 3, 6, 9, 12, and 15. During this period, individual heifer DMI was measured using an automated feed intake measuring system (Model 4000E; GrowSafe Systems Ltd., Airdrie, Alberta, Canada). Initial and final shrunk BW did not differ (P > 0.36) among treatments. On d 1, plasma Cp concentrations increased (P < 0.01) sharply in vaccinated heifers but not control heifers and were greater (P < 0.05) in vaccinated vs. control heifers on d 3, 6, 9, and 12 relative to injection. Daily DMI did not differ (P = 0.66) among treatments (average = 9.1 kg/d; SEM = 0.34); however, ADG and G:F were greater (P ≤ 0.05) for control vs. vaccinated heifers (1.14 vs. 0.87 kg/d and 0.13 and 0.10 kg, respectively; SEM = 0.064 and 0.011). These data indicate that within a 2 wk period after vaccination, beef calves experience an acute-phase protein response, which may result in reduced ADG and feed efficiency.

RESUMO

Increased susceptibility to infection has long been observed among patients with systemic lupus erythematosus, and still represents a chief cause of morbidity and mortality in these patients. This is due in part to the severity of infection and to the difficulty of early diagnosis owing to the similarity between SLE flares and infection. Epidural infection is an uncommon condition, and a most rare condition caused by salmonella, which accounts for a broad spectrum of human illnesses from gastroenteritis and typhoid fever to the asymptomatic carrier state. We report the first case of epidural abscess caused by Salmonella enteritidis in a female with SLE with protean manifestations treated by intravenous antibiotics and surgery with full recovery of neurological symptoms, illustrating the importance of performing an early diagnosis and prompt treatment.

RESUMO

We compared outcomes of alveolar hemorrhage (AH) in juvenile (JSLE) and adult onset SLE (ASLE). From 263 JSLE and 1522 ASLE, the AH occurred in 13 (4.9%) and 15 (1.0%) patients, respectively (p < .001). Both groups had comparable disease duration (2.6 ± 3.0 vs. 5.6 ± 7.0 years, p = .151) and median SLEDAI scores [17.5 (2 to 32) vs. 17.5 (3 to 28), p = 1.000]. At AH onset, a higher frequency of JSLE were already on a high prednisone dose ( > 0.5 mg/kg/day) compared to ASLE (54% vs. 15%, p = .042). The mean drop of hemoglobin was significantly lower in JSLE (2.9 ± 0.9 vs. 5.5 ± 2.9 g/dL, p = .006). Although treatments with methylprednisolone, plasmapheresis, intravenous immunoglobulin and cyclophosphamide were similar in both groups (p > .050), regarding outcomes, there was a trend in high frequency of mechanical ventilation use (85% vs. 47%, p = .055) and also significant mortality (69% vs. 13%, p = .006) in JSLE compared to ASLE. The sepsis frequency was comparable in both groups (50% vs. 27%, p = .433). We have identified that AH in JSLE has a worse outcome most likely related to respiratory failure. The AH onset in JSLE already treated with high-dose steroids raises the concern of inadequate response to this treatment and reinforces the recommendation of early aggressive alternative therapies in this group of patients.

RESUMO

Synovial lipoma arborescens is a rare and benign intra-articular pathology, of unknown etiology, characterized by a villous and lipomatous proliferation of synovial tissue. It presents with atypical clinical manifestations, usually located in the knee, represented as recurrent joint effusions and painless swelling joint. The magnetic resonance is the most specific test and can often even avoid the synovial biopsy. We related the case of a female patient with mechanical pain in the knee with indolent evolution for 18 years, clinical and radiological compatible with osteoarthritis. With the finding of a localized unilateral increase of the suprapatellar bursa without perceptible joint effusion and ultrasonographic aspect of an exuberant nodular synovitis, the possibility of villonodular pigmented synovitis had to be discarded by synovial biopsy. Even after this procedure, her diagnosis was not clear, being reported to rheumatology evaluation due to histopathology findings confused with rheumatoid arthritis. The set of clinical, laboratory, magnetic resonance and histological review of synovial tissue confirmed the diagnosis of synovial lipoma arborescens, excluding the possibility of rheumatoid arthritis.

RESUMO

In the present study we investigated whether individuals would take advantage of an extrinsic and incidental reappraisal strategy by giving them precedent descriptions to attenuate the emotional impact of unpleasant pictures. In fact, precedent descriptions have successfully promoted down-regulation of electrocortical activity and physiological responses to unpleasant pictures. However, the neuronal substrate underlying this effect remains unclear. Particularly, we investigated whether amygdala and insula responses, brain regions consistently implicated in emotional processing, would be modulated by this strategy. To achieve this, highly unpleasant pictures were shown in two contexts in which a prior description presented them as taken from movie scenes (fictitious) or real scenes. Results showed that the fictitious condition was characterized by down-regulation of amygdala and insula responses. Thus, the present study provides new evidence on reappraisal strategies to down-regulate emotional reactions and suggest that amygdala and insula responses to emotional stimuli are adaptive and highly flexible.

RESUMO

Antiphospholipid syndrome (APS) is a disorder of coagulation that causes thrombosis as well as pregnancy-related complications, occurring due to the autoimmune production of antibodies against phospholipid. Full anticoagulation is the cornerstone therapy in patients with thrombosis history, and this can lead to major bleeding. During a 3-year period, 300 primary and secondary APS patients were followed up at the Rheumatology Division of the authors' University Hospital. Of them, 255 (85%) were women and 180 (60%) were of reproductive age. Three of them (1%) had severe hemorrhagic corpus luteum while receiving long-term anticoagulation treatment and are described in this report. All of them were taking warfarin, had elevated international normalized ratio (>4.0) and required prompt blood transfusion and emergency surgery. Therefore, we strongly recommend that all women with APS under anticoagulation should have ovulation suppressed with either intramuscular depot-medroxyprogesterone acetate or oral desogestrel.
