Design and Development of a Web-Based Prospective Nationwide Registry for Ocular Inflammatory Diseases: UVEITE.PT - The Portuguese Ocular Inflammation Registry

Uveitis is a heterogeneous collection of infrequent diseases, which poses significant challenges to cost-effective research in the field. Medical registries are being increasingly recognized as crucial tools to provide high-quality data, thus enabling prospective clinical research. This paper describes the design and technical structure development of an innovative countrywide electronic medical record for uveitis, Uveite.pt, and gives an overview of the cohort registered since its foundation, March 2020.Uveite.pt is an electronic medical record platform developed by the Portuguese Ocular Inflammation Group (POIG), a scientific committee of the Portuguese Ophthalmology Society. This is a nationwide customized web-based platform for uveitis patients useful for both clinical practice and real-world-based research, working as a central repository and reporting tool for uveitis. This paper describes the technical principles, the design and the development of a web-based interoperable registry for uveitis in Portugal and provides an overview of more than 400 patients registered in the first 18 months since inception.In infrequent diseases, the existence of registries enables to gather evidence and increase research possibilities to clinicians. The adoption of this platform enables standardization and improvement of clinical practice in uveitis. It is useful to apprehend the repercussion of medical and surgical treatments in uveitis and scleritis, supporting clinicians in the strict monitoring of drug adverse reactions and surgical outcomes.

Estimating sequence diversity of prion protein gene (PRNP) in Portuguese populations of two cervid species: red deer and fallow deer

Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now a rising concern in wildlife within Europe, after the detection of the first case in Norway in 2016, in a wild reindeer and until June 2022 a total of 34 cases were described in Norway, Sweden and Finland. The definite diagnosis is post-mortem, performed in target areas of the brain and lymph nodes. Samples are first screened using a rapid test and, if positive, confirmed by immunohistochemistry and Western immunoblotting. The study of the genetics of the prion protein gene, PRNP, has been proved to be a valuable tool for determining the relative susceptibility to TSEs. In the present study, the exon 3 of PRNP gene of 143 samples from red deer (Cervus elaphus) and fallow deer (Dama dama) of Portugal was analysed. Three single nucleotide polymorphisms (SNPs) were found in red deer - codon A136A, codon T98A, codon Q226E - and no sequence variation was detected in fallow deer. The low genetic diversity found in our samples is compatible with previous studies in Europe. The comparison with results from North America suggests that the free-ranging deer from our study may present susceptibility to CWD, although lack of experimental data and the necessity of continuous survey are necessary to evaluate these populations.

Prevalence and Risk Factors for Hepatitis E Virus in Wild Boar and Red Deer in Portugal

Hepatitis E virus (HEV) is a zoonotic foodborne virus with an annual infection prevalence of 20 million human cases, which seriously affects public health and economic development in both developed and developing countries. To better understand the epidemiology of HEV in Central Portugal, a cross-sectional study was conducted from 2016 to 2023 with sera samples from wild ungulates. The seroprevalence and risk factors for HEV seropositivity were evaluated in the present study. Specifically, antibodies against HEV were determined by a commercial enzyme-linked immune-sorbent assay (ELISA). Our results show that in the 650 sera samples collected from 298 wild red deer and 352 wild boars in Portugal, 9.1% red deer and 1.7% wild boar were positive for antibodies to HEV. Regarding age, the seropositivity in juvenile wild ungulates was 1.3%, whereas it was 7.2% in adults. Logistic regression models investigated risk factors for seropositivity. The odds of being seropositive was 3.6 times higher in adults than in juveniles, and the risk was 4.2 times higher in red deer than in wild boar. Both wild ungulate species were exposed to HEV. The higher seroprevalence in red deer suggests that this species may make a major contribution to the ecology of HEV in Central Portugal. Further research is needed to understand how wildlife affects the epidemiology of HEV infections in Portugal.

First morphological and molecular isolation of Talaromyces marneffei in beech marten (Martes foina) in Portugal

Talaromyces marneffei is a zoonotic fungus that mostly infects immunocompromised individuals. For the first time, this fungus was isolated in an adult beech marten (Martes foina) hit by a car, found dead in Penamacor, Portugal. During the necropsy, different samples (skin, fur, lymph nodes, lung, spleen, kidneys, and brain) were collected and processed for microbiology (including mycology) and molecular biology. T. marneffei was identified through its mycological characteristics and confirmed by PCR in hair samples. No other lesions or alterations were reported, except a concomitant presence of M. avium subsp. paratuberculosis in lung, kidney and brain samples. To the authors' knowledge, this is the first description of this fungus beech marten, as well as the first case of co-infection with M. avium subsp. paratuberculosis in wildlife fauna. These results suggest a sylvatic life-cycle of T. marneffei, involving beech martens, in Portugal.

Uveitis in patients with oligoarticular juvenile idiopathic arthritis and juvenile spondyloarthritis/enthesitis related arthritis: is there any difference?

Juvenile idiopathic arthritis (JIA) is the most common systemic disease causing uveitis in childhood and adolescence.

Talaromyces marneffei isolated from nasal swabs in Portugal

Mycobiota are essential to the health of any living being, creating a balanced and complex interaction between bacteria, the immune system and the tissue cells of the host. Talaromyces marneffei (also known as Penicillium marneffei) is a dimorphic fungus, endemic in South Asia, that often causes a life-threatening systemic fungal infection (called penicilliosis), particularly in immunocompromised hosts. Nasal swabs from 73 healthy volunteers were analysed to characterise their mycobiota, through its cultural characteristics, morphology and molecular methods (PCR). All volunteers were also asked to answer to an anonymous questionnaire. Three women were positive (and asymptomatic) for T. marneffei. One of them was reported to have lupus. This study contributes to improving our knowledge about human normal mycobiota, identifying mycotic agents that may cause complicated systemic infections (as T. marneffei), especially in immunosuppressed patients, as well as other possible risk factors of exposure or prognosis.

Outcome of Uveitis in Juvenile Idiopathic Arthritis and Spondyloarthritis Patients - A 5-Year Follow-Up Study

OBJECTIVE

Uveitis is a frequent complication of juvenile idiopathic arthritis (JIA) and spondyloarthritis (SpA). The aim of this study is to evaluate the prevalence and risk factors for complications associated with uveitis in patients with JIA and SpA.

METHODS

A longitudinal, monocentric cohort study that included patients diagnosed with JIA and SpA who developed uveitis. Demographic, laboratory, and clinical data were collected including complications of uveitis, HLA-B27, antinuclear antibodies, erythrocyte sedimentation rate, C-reactive protein, visual acuity and DMARD treatment. Comparison between groups (complicated versus uncomplicated uveitis) was evaluated using chi-square, t test and Mann-Whitney U test. Logistic regression was performed to determine predictors of complications.

RESULTS

A total of 270 patients were evaluated, of which 37 patients (13.7%) had uveitis and were included in this study. Twenty patients were female (54.1%), aged 11.9±8.7 years at diagnosis of SpA/JIA and 15.3±9.9 years at diagnosis of uveitis. Twenty-seven patients (73.0%) had a diagnosis of JIA (23 with oligoarticular disease) and in 12 patients (32.4%) uveitis was the first manifestation. Fifteen (40.5%) patients exhibited complications during follow-up period. Eleven patients (29.7%) underwent ophthalmologic surgery. Complications were significantly higher in patients with JIA (51.9% vs 10.0% in SpA, p=0.03), as was the need for surgery (40.7% vs 0%, p=0.02). Complications in JIA were significantly more frequent in patients who had uveitis as the initial presentation (50.0% vs 7.7%, p=0.03); no significant differences were found between the groups in the other variables studied. Univariate logistic regression analysis showed that uveitis as the first manifestation of JIA (OR 12.0, confidence interval 95% 1.21-118.89, p=0.03) is a significant predictor of complications.

CONCLUSION

We found higher rates of complications and need for ophthalmologic surgery in patients with JIA-associated uveitis. The initial presentation of JIA as uveitis is significantly associated with the occurrence of uveitis complications, so it is essential that there is a collaboration between ophthalmologist and rheumatologist in the diagnosis and treatment of these patients.

The 2021 Portuguese Society of Ophthalmology joint guidelines with Paediatric Rheumatology on the screening, monitoring and medical treatment of juvenile idiopathic arthritis-associated uveitis

AIM

To develop the first Ophthalmology joint guidelines with Paediatric Rheumatology with recommendations on the screening, monitoring and medical treatment of juvenile idiopathic arthritis-associated uveitis (JIA-U), endorsed by the Portuguese Society of Ophthalmology (SPO).

METHODS

A systematic literature review was conducted to include publications up to July 14th 2020, with no language restrictions, in order to include all the international position papers/guidelines concerning the medical management of JIA-U and randomised clinical trials assessing the efficacy and safety of medical treatment in this field. We searched through MEDLINE (PubMed), Scopus, Web of Science and Cochrane Library. The Delphi modified technique to generate consensus was used. Preliminary evidence statements were subject to an anonymous agreement assessment and discussion process using an online survey, followed by further discussion and update at a national meeting. A draft of the manuscript with all recommendations was then circulated among all participants and suggestions were incorporated. The final version was again circulated before publication.

RESULTS

Twenty-six recommendations were developed focusing on the following topics: general management (3), screening and follow-up of uveitis (4), treatment (17) and health education in JIA-U among patients and families (2).

CONCLUSION

These guidelines were designed to support the shared medical management of patients with JIA-U and emphasize the need for a multidisciplinary approach between Ophthalmology and Paediatric Rheumatology regarding the comprehensive care of JIA-U. We acknowledge that updating these recommendations will be warranted in the future, as more evidence becomes available.

Efficacy and safety of intravitreal and periocular injection of corticosteroids in non-infectious uveitis: a systematic review

Uveitis is among the leading causes of visual loss in the working age population. In non-infectious uveitis, corticosteroids are the first line therapy. We sought to review systematically the evidence regarding the regional corticosteroid delivery modalities in the treatment of non-infectious uveitis. A five-database search (Pubmed, ISI Web of Science, Cochrane, ClinicalTrials.gov, and Scopus) was performed from inception to February, 2021. Nineteen studies with a total of 1935 eyes of 1753 patients were selected from 8922 abstracts retrieved by the initial search. The most frequently compared regimens were intravitreal triamcinolone acetonide injection and orbital floor triamcinolone acetonide injection (2 studies), intravitreal triamcinolone acetonide injection and posterior sub-Tenon triamcinolone acetonide injection (2 studies), and posterior sub-Tenon triamcinolone acetonide injection with the intravitreal dexamethasone implant (2 studies). Our results show that the intravitreal injection of corticosteroids is more effective, but is associated with more adverse events, than periocular injection. Some evidence supports the use of subconjunctival triamcinolone acetonide over intravitreal/periocular triamcinolone acetonide. Moreover, the overall results of 0.59 mg dosage of the intravitreal fluocinolone acetonide implant were superior to those from the 2.1 mg dose. The evidence, however, is not robust and further studies with standardized outcomes are warranted.

A painful red eye in an intravenous drug abuser: When not everything is what it seems

INTRODUCTION

Endogenous endophthalmitis is a rare but devastating ocular infection, resulting from microbial seeding of the eye during bacteremia or fungemia. Among other sources of septicemia, intravenous drug abuse is a significant risk factor, and endogenous endophthalmitis should always be thought of in any patient with a history of injectable drug use, presenting with a painful vision loss and a red inflamed eye.

CASE DESCRIPTION

We report the case of a 47-year-old male, with a history of injectable drug consumption, who presented to our emergency department complaining of a painful red eye and recent deterioration of visual acuity. After the first clinical hypothesis of endogenous endophthalmitis being considered, the final diagnosis of Human Leukocyte Antigen (HLA) B27-associated acute anterior uveitis was established.

CONCLUSION

Ocular inflammation is one of the most challenging fields in all ophthalmology. Several inflammatory disorders, ranging from a wide variety of infectious and non-infectious conditions, can present themselves with the same clinical signs and symptoms, making their diagnosis extremely defiant.

Scrapie at Abattoir: Monitoring, Control, and Differential Diagnosis of Wasting Conditions during Meat Inspection

Wasting disease in small ruminants is frequently detected at slaughterhouses. The wasting disorder is manifested by the deterioration of the nutritional and physiological state of the animal indicated by thinness, emaciation, and cachexia. Evidence of emaciation and cachexia, alone, are pathological conditions leading to carcass condemnation during an inspection. Several diseases are associated with a wasting condition, including scrapie, pseudotuberculosis, tuberculosis, paratuberculosis, Maedi Visna, and tumor diseases. On the other hand, parasitic diseases, nutrition disorders, exposure or ingestion of toxins, metabolic conditions, inadequate nutrition due to poor teeth, or poor alimentary diet are conditions contributing to poor body condition. Classical and atypical scrapie is naturally occurring transmissible spongiform encephalopathies in small ruminants. The etiological agent for each one is prions. However, each of these scrapie types is epidemiologically, pathologically, and biochemically different. Though atypical scrapie occurs at low incidence, it is consistently prevalent in the small ruminant population. Hence, it is advisable to include differential diagnosis of this disease, from other possibilities, as a cause of wasting conditions detected during meat inspection at the abattoir. This manuscript is a review of the measures in force at the abattoir for scrapie control, focusing on the differential diagnosis of gross lesions related to wasting conditions detected in small ruminants during meat inspection.

Dietary tryptophan supplementation does not affect growth but increases brain serotonin level and modulates the expression of some liver genes in zebrafish (Danio rerio)

This study aimed at assessing the effects of the dietary tryptophan (Trp) supplementation on growth and feed utilization, brain serotonin content, and expression of selected liver genes (involved in the liver serotonin pathway, protein synthesis degradation, and antioxidant activity) in zebrafish. A growth trial was conducted with zebrafish juveniles fed five experimental isoproteic (40%DM) and isolipidic (8%DM) fishmeal-based diets containing graded levels of Trp: a Trp-non-supplemented diet (diet Trp0, with 0.22% Trp) and four Trp-supplemented diets containing 2-16 times higher Trp content (diets Trp2, Trp4, Trp8, and Trp16 with 0.40, 0.91, 2.02, and 3.34% Trp, respectively). Diets were tested in quadruplicate, with fish being fed twice a day, 6 days a week for 6 weeks to apparent visual satiation. At the end of the trial, growth performance and feed utilization were assessed, and fish from all experimental groups were sampled for whole-body composition analysis. In addition, fish fed low (Trp0), medium (Trp4), and high (Trp16) Trp diets were also sampled for analysis of brain serotonin content and liver gene expression. Tested tryptophan levels did not influence growth performance nor feed intake. However, values of energy and nitrogen retention as well as body energy content indicate a better feed utilization with diets containing around 0.9% and 2.0% DM Trp. Brain serotonin content increased with increasing dietary tryptophan levels. In addition, regarding liver genes, dietary treatment had a modulatory effect on the expression of Htr1aa and Htr2cl1 genes (encoding for serotonin receptors), TPH1a gene (encoding for tryptophan hydroxylase, the rate-limiting enzyme in the synthesis of serotonin from tryptophan), TOR gene (involved in protein synthesis), and Keap1 gene (involved in antioxidant responses).

The Role of Atopy in the Choroidal Profile of Keratoconus Patients

Purpose

Although classically classified as a non-inflammatory condition, an inflammatory basis for keratoconus (KC) appears to be a growing evidence. Recently, it has been shown that KC patients have an increased choroidal thickness (CT). Among inflammatory disorders, atopy has been associated with KC development; therefore, the aim of this study was to evaluate if the increased CT in patients with KC is related to atopy.

Methods

This is an analytical cross-sectional study of patients with KC. Patients were classified as atopic and non-atopic according to their atopy history (allergic rhinoconjunctivitis (AR), asthma (AA) and/or atopic dermatitis (AD)) and were also classified based on their eye rubbing habits. Choroidal profile of all subjects was evaluated using a Spectralis optical coherence tomography (OCT) device with enhanced depth imaging (EDI) mode. CT was measured and compared between groups at the center of the fovea and at 500 µm intervals along a horizontal section. A multivariable analysis, adjusted for sex, age, spherical equivalent, history of medication and atopy, was performed to assess the influence of atopy in CT.

Results

Of the 80 patients included, 51 were atopic and 29 non-atopic. Atopic patients showed a thicker choroid in every measured location than the non-atopic patients (mean subfoveal CT 391.53 µm vs 351.17 µm, respectively), although the differences were not statistically different. The multivariable analysis revealed that being atopic makes the choroid statistically thicker, on average, 55.14 µm, when compared to non-atopic patients (p=0.043). Furthermore, patients who are frequent eye rubbers have significantly thicker choroids than non-rubbers (p=0.004).

Conclusion

Although some results do not reach statistical significance, atopic KC patients seem to have thicker choroids compared with non-atopic KC patients, suggesting a possible role for atopy in the choroidal profile of KC. This constitutes a completely new sight in this field of research that needs further investigation.

Epidemiology of Uveitis in a tertiary care centre in Portugal

Purpose: Evaluate the prevalence and incidence, demographic characteristics, anatomical classification, concomitant complications and treatment of uveitis, as well as its association with systemic diseases in the northern Portuguese population referred to a tertiary care centre (São João Hospital, Porto).Methods: A retrospective observational study of 545 consecutive uveitis cases was performed between 12th April 2012 and the 26th October 2017. Uveitis was classified according to Standard Uveitis Nomenclature, while aetiology and complications were diagnosed by specific clinical and laboratory testing.Results: Prevalence was calculated to be 12,4 cases per 100,000 people while incidence was 3.9 cases per 100,000 people annual incidence. The ratio of females to males was 1.32:1 and the mean age at diagnosis was 47,86 years. Anterior uveitis was the most common classification making up 47.5%, followed by non-infectious posterior uveitis 18,0%, infectious posterior uveitis 8,4%, intermediate uveitis 5,5% and panuveitis 4,2%. Extra-uveal entities made up the rest of the causes (16.4%). In terms of aetiology, the majority of uveitis was idiopathic (32,1%) followed by axial spondylarthritis (12.1%), Behçet's disease (8,8%), sarcoidosis (6,1%), tuberculosis (5,5%), herpes (5,1%), toxoplasmosis (3,1%) among other less frequent causes.Conclusion: In our referral region, 72% of uveitis cases were correctly identified surpassing other studies. There was a higher rate of intermediate uveitis and lower number of panuveitis cases when compared to a previous Portuguese study. Extensive monitoring of the development of uveitis by international multicentre prospective studies could be useful for increasing practitioner awareness and diagnostic approach.

Efficacy and Safety of Corticosteroid Implants in Non-infectious Uveitis: A Systematic Review with Network Meta-analysis

BACKGROUND/AIMS

To compare different existent implants for noninfectious uveitis.

METHODS

We performed a systematic review of randomized clinical trials (RCTs), searching in five electronic databases and screening reference lists of included studies and relevant reviews. We performed network meta-analysis to compare 0.18 mg fluocinolone acetonide implants, 0.70 mg and 0.35 mg dexamethasone implants, and sham procedures.

RESULTS

Eight RCTs were included in this systematic review, of which three articles from two studies (n = 358 patients) were included in network meta-analysis. The 0.70 mg dexamethasone implant (at 1.5 months) was associated with better results than the 0.18 mg fluocinolone acetonide implant (at 1 month) at improving vitreous haze grading (RR = 2.96; 95%CI = 1.23-7.07), and with less frequently development of cataracts at 12 (RR = 0.36; 95%CI = 0.17; 0.79) and 36 months (RR = 0.37; 95%CI = 0.20; 0.71).

CONCLUSIONS

In the short term, the 0.70 mg dexamethasone implant is superior at improving vitreous haze, and shows lower risk of cataracts. However, additional RCTs with standardized outcomes are needed.

Sustained Control from Recurring Non-Infectious Uveitic Macular Edema with 0.19 mg Fluocinolone Acetonide Intravitreal Implant - A Case Report

In January 2013, a 54-year-old pseudophakic woman was referred to the ocular inflammation clinic with a diagnosis of panuveitis, already on oral cyclosporine (100 mg/day) since 2010. She was a monocular patient, with the left eye eviscerated due to trauma and secondary endophthalmitis in 1995. She had experienced similar recurring episodes between 2010 and 2013. Examination revealed best-corrected visual acuity (BCVA) of 20/200. The anterior segment revealed the presence of flare and absence of cells. Intraocular pressure (IOP) was 11 mmHg. Fundus examination revealed the presence of anterior vitreous organization, exuberant cystoid macular edema (CME) and peripheral Dalen-Fuchs nodules with no activity. Systemic workup showed no changes, and a presumptive diagnosis of sympathetic ophthalmia was made. Initial therapy included topical and systemic corticosteroids. Cyclosporine was replaced with methotrexate (20 mg/week) due to nephrotoxicity. There was marked improvement in anterior inflammation and vitreous organization, but the ME remained exuberant (central ring thickness of 0.7 mm). Over the subsequent 4 years of follow-up, the patient received two intravitreous injections of a dexamethasone extended-release implant (Ozurdex®), with normalization of macular thickness and improvement in visual acuity (VA), but ME recurred around 6 months post-injection. During this period, the patient also underwent three sub-tenon injections of triamcinolone, with marked improvement of ME, but ME recurred between 4 and 6 months after treatment. She was thus recommended for treatment with a fluocinolone extended-release implant (ILUVIEN®). Post-implantation (3-year follow-up), she had controlled anterior inflammation without ME (central macular thickness of 248 µm). This case suggests that sustained control of inflammation enables better control of ME, and benefits may persist even after cessation of the direct anti-inflammatory effect of the implant. FUNDING: Alimera Sciences Ltd funded the Rapid Service Fees.

Elizabethkingia meningoseptica and Contact Lens Use

A 47-year-old man presented to our emergency department complaining of acute ocular pain and redness of his left eye. Ophthalmological antecedents included use of semi-rigid contact lens and primary open-angle glaucoma. Slit-lamp examination revealed a small central corneal ulcer associated with stromal inflammatory infiltrate. Scraping from the corneal ulcer was positive for Elizabethkingia meningoseptica. He was empirically treated with topical 0.5% levofloxacin and 0.3% gentamicin, and five weeks later the infection had resolved. In this case report we describe the uncommon association between contact lens and Elizabethkingia meningoseptica. Despite possible serious complications associated with this atypical agent, prompt diagnosis and adequate treatment lead to good visual prognosis.

Mesenteric lymph node granulomatous lesions in naturally infected wild boar (Sus scrofa) in Portugal--Histological, immunohistochemical and molecular aspects

Several studies have demonstrated that wildlife reservoirs of mycobacteria are responsible for the maintenance and spreading of the infection to livestock and wildlife counterparts. Recent data report the role of wild boar (Sus scrofa) as a reservoir for Mycobacterium bovis. This study was conducted to evaluate the chronic inflammatory response in the mesenteric lymph nodes (MLN) of wild boar with granulomatous lymphadenitis (n=30). Morphological parameters of the lesions were recorded. The expression of CD3 and CD79α molecules was evaluated by immunohistochemistry. Molecular genotyping and culture to identify mycobacteria were performed. The lesions consisted mainly of stage III and stage IV granulomas. CD3 and CD79α positive cells were observed in 15 (50%) and in 11 (36.6%) MLN, respectively. In these lesions, higher percentages of T lymphocytes were found and a limited number of animals exhibited a tendency for an increased percentage of B lymphocytes. Our results suggest that there are similar percentages and distribution patterns of CD3 and CD79α in the lesions, regardless of the presence of Mycobacterium avium subsp. paratuberculosis (Map), M. bovis or Map-M. bovis co-infection, and confirm that wild boar is both susceptible and could be an important Map and M. bovis wild reservoir in the study area.

Malignant hypertensive retinopathy as a presenting sign of an occult dead fetus

We report one case of malignant hypertensive retinopathy as a presenting sign of fetal death in utero. Ophthalmic examination (including intravenous fluorescein angiography and optical coherence tomography) and obstetric and systemic evaluation were performed, providing a multidisciplinary approach. A 33-year-old overweight woman (body mass index 47 kg/m²) with no systemic or ocular known disease was admitted to our emergency department with a one-week history of bilateral vision loss and no systemic complaints. On examination, best corrected visual acuity was 1/10 in the right eye and 1/10 in the left eye. Anterior segment examination of both eyes was unremarkable. Ophthalmoscopic fundus findings included bilateral optic disc edema, diffuse cotton wool spots, intraretinal exudates, retinal hemorrhages, and multiple serous retinal detachments involving both maculae. Physical examination revealed a blood pressure of 220/110 mmHg. Further systemic workup revealed a previously unknown 35-week pregnancy with a dead fetus. An emergency cesarean section was performed. Pre-eclampsia is a life-threatening disorder for both mother and fetus. This case highlights the need to rule out pre-eclampsia in all women of childbearing age presenting with ocular signs of malignant hypertension, even without external signs of pregnancy.

Carrion consumption by Dasyprocta leporina (Rodentia: Dasyproctidae) and a review of meat use by agoutis

The consumption of the carrion of a tapiti by a reintroduced female Dasyprocta leporina was observed in the wild. Herein, besides describing this event, we reviewed other evidence of vertebrate consumption by agoutis. Most of the studies describing this behaviour have been carried out in captivity. The preyed animals included birds and small rodents, which were sometimes killed by agoutis. This pattern suggests that this is not an anomalous behaviour for the genus, reflecting its omnivorous habits. This behaviour can be a physiologically sound feeding strategy, so new studies should focus on the temporal variation in the consumption of this resource, possibly related to food scarcity periods or to reproductive seasons, when the need for high-quality food tends to increase.

New Insights into Mycobacterium bovis Prevalence in Wild Mammals in Portugal

A survey to determine the prevalence of Mycobacterium bovis in wild mammals in Portugal was conducted by testing samples from hunted animals and those found dead between 2009 and 2013. In this study, we investigated 2116 wild mammals. Post-mortem examinations were performed, and tissues were collected from wild mammals representing 8 families and 11 different species, with a total of 393 animals analysed. Cultures were performed, and acid-fast isolates were identified by PCR. Tissues were also screened for Mycobacterium bovis by directly extracting DNA and testing for the Mycobacterium bovis-specific sequences. Mycobacterium bovis prevalence was 26.9% (95% CI: 22.8-31.5%). Mycobacterium bovis was recorded in 106 of the 393 studied species: prevalence by species were 26.9% (95% CI: 16.8-40.2%) in red foxes, 20.0% (95% CI: 7.0-45.2%) in Egyptian mongooses, 21.4% (95% CI: 16.2-27.7%) in wild boar and 38.3% (95% CI: 29.9-47.4%) in red deer. Mycobacterium bovis infection was detected in six of eight taxonomic families. For some species, the small sample sizes obtained were a reflection of their restricted range and low abundance, making estimates of infection prevalence very difficult (1 beech marten of 4; 1 Eurasian otter of 3; 2 common genet of 3). Infection was not detected in European badgers, hedgehog, wild rabbits and hare. The results of this study confirm the presence of Mycobacterium bovis infection in wild carnivores in Portugal.

Metabolic Syndrome in Bipolar Illness: Patient Concepts and Screening Effectivity

Introduction:

Metabolic Syndrome (MS) is constituted by a set of specific metabolic alterations being postulated that the main dysfunction is insulin resistance. Estimates point to higher prevalence of MS in bipolar patients, between 30 to 35%. Cost-effective screening methods, not recurring to blood test, have been researched.

Objectives:

Analyse knowledge and importance given to MS in bipolar patients. Test the viability of MS screening without blood tests.

Methodology:

Observational, cross-sectional study. Random sample of 15 adult bipolar patients, in euthymic phase. Semi-structured interview, YMRS, HAMD were applied. MS diagnosis investigated according to the International Diabetes Federation (IDF) criteria. MS screening was defined positive if blood pressure ≥ 130/85 or anti-hypertensive medication and abdominal perimeter > 90 in males or > 80 in females. A questionnaire about knowledge, attitudes and concerns on MS was applied.

Main results:

14 patients completed the investigation protocol. Five (36%) met IDF criteria for metabolic syndrome. Screening sensitivity was 80% and specificity 78%. Twelve patients (80%) were overweigh or obese. Mean IMC in patients that met IDF criteria for MS was 30 while in the other group mean IMC was 26. Only 3 (20%) have ever heard about MS, but the majority of the patients were concerned, in decreasing order, about weight gain, blood pressure cholesterol and hyperglycemia control.

Conclusions:

Although limited by small sample size, this study strengthens the idea that MS screening can be effective in clinical practice, it also indicates the need to educate BP patients about MS and to prevent overweight.

[Psychotherapy in AIDS]

Infection with human immunodeficiency virus creates the expectation of terrible disease marked by an inexorable physical decline. The majority of the affected patients are relatively young and pleasure plays an important role in their lives which will be marked by the possibility of an early death. This is a peculiar situation with an unpredictable evolution that mandates a reformulation of the psychotherapeutic approach mainly in the achievable goals and the practical way to manage them. We describe our two years psychiatric and psychotherapeutic experience with AIDS patients followed by the H.S.M. Infectious Diseases Department.
