Is Steatotic Liver Disease Related to Poor Outcome in COVID-19-Hospitalized Patients?

Background: Steatotic liver disease (SLD) has been linked to more exacerbated inflammatory responses in various scenarios. The relationship between SLD and COVID-19 prognosis remains unclear. Our aim was to investigate the impact of SLD on the outcome of COVID-19. Methods: Patients hospitalized with confirmed COVID-19 and who underwent laboratory tests and chest CT scans were included. SLD was assessed by measuring the attenuation coefficient on CT scans. The relationship between SLD, the severity of COVID-19 clinical presentation and in-hospital mortality were assessed. Results: A total of 610 patients were included (mean age 62 ± 16 years, 64% male). The prevalence of SLD was 30%, and the overall in-hospital mortality rate was 19%. Patients with SLD were younger (58 ± 13 vs. 64 ± 16 years, p < 0.001) and had a higher BMI (32 ± 5 vs. 28 ± 4 kg/m2, p = 0.014). Admission AST values were higher in patients with SLD (82 ± 339 vs. 50 ± 37, p = 0.02), while D-dimer (1112 ± 2147 vs. 1959 ± 8509, p = 0.07), C-reactive protein (12 ± 9 vs. 11 ± 8, p = 0.27), ALT (67 ± 163 vs. 47 ± 90, p = 0.11), ALP (83 ± 52 vs. 102 ± 125, p = 0.27), and GGT (123 ± 125 vs. 104 ± 146, p = 0.61) did not significantly differ compared to patients without SLD. No difference was observed regarding lung parenchyma involvement >50% (20% vs. 17%, p = 0.25), hospital length of stay (14 ± 19 vs. 16 ± 23 days, p = 0.20), hemodialysis support (14% vs. 16%, p = 0.57), use of mechanical ventilation (20% vs. 20%, p = 0.96), and in-hospital mortality (17% vs. 20%, p = 0.40) when comparing patients with and without SLD. Conclusions: SLD showed no significant association with morbidity and mortality in patients with COVID-19.

Membranous urethral length is the single independent predictor of urinary continence recovery at 12 months following Retzius-sparing robot-assisted radical prostatectomy.

The influence of anatomical parameters on urinary continence (UC) after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) remains uncharted. Our objective was to evaluate their association with UC at 3, 6 and 12 months post-operatively. Data from patients who underwent RS-RARP were prospectively collected. Continence was defined as no pad use. Anatomic variables were measured on preoperative magnetic resonance imaging (MRI). Regression analyses were performed to identify predictors of UC at each time point. We included 158 patients with a median age of 60 years, most of whom had a localized tumor (≤ cT2). On multivariate analyses, at 3 months post-surgery, urinary incontinence (UI) rises with age, odds ratio (OR) 1.07 [95% confidence interval (CI) 1.004-1.142] and with prostate volume (PV), OR 1.029 (95% CI 1.006-1.052); it reduces with longer membranous urethral length (MUL), OR 0.875 (95% CI 0.780-0.983) and with higher membranous urethral volume (MUV), OR 0.299 (95% CI 0.121-0.737). At 6 months, UI rises with PV, OR 1.033 (95% CI 1.011-1.056) and decreases with MUV, OR 0.1504 (95% CI 0.050-0.444). Significantly, at 12 months post-surgery, the only predictor of UI is MUL, OR 0.830 (95% CI 0.706-0.975), establishing a threshold associated with a risk of UI of 5% (MUL > 15 mm) in opposition to a risk of 25% (MUL < 10 mm). This single institutional study requires external validation. To our knowledge, this is the first prospective cohort study supporting MUL as the single independent predictor of UC at 12 months post-surgery. By establishing MUL thresholds, we enable precise patient counseling.

Hunting for Answers: Assessing Brucella spp. Seroprevalence and Risks in Red Deer and Wild Boar in Central Portugal.

Between 2016 and 2023, a cross-sectional study was conducted in the central region of Portugal in order to better understand the epidemiology and public health risks resulting from the handling and consumption of game animals infected with Brucella spp. The seroprevalence and risk factors for Brucella spp. seropositivity were evaluated. Antibodies against Brucella spp. were determined using a commercial enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's instructions. Results showed that in the 650 serum samples collected from red deer (n = 298) and wild boars (n = 352) in Portugal, 21.7% (n = 141; 95% CI: 18.6-25.1%) tested positive. Wild boar had a significantly higher prevalence (35.5%; 95% CI: 30.5-40.8%) than red deer (5.4%, 95% CI: 3.1-8.6%; p ≤ 0.001). Risk factors for seropositivity were investigated using multivariable logistic regression models. The odds of being seropositive was 8.39 (95% CI: 4.75-14.84; p ≤ 0.001) times higher in wild boar than in red deer. Correlations between sex, age, body condition, and seropositivity could not be observed. The higher seroprevalence in wild boar suggests that this species may primarily contribute to the Brucella spp. ecology in central Portugal.

Segmentation-Based Analysis of T2- and T1-Weighted Dynamic Magnetic Resonance Images Provides Adequate Observer Agreement in the Evaluation of Interstitial Lung Disease.

OBJECTIVE: The aim of the study is to quantify observer agreement in the magnetic resonance imaging (MRI) classification of inflammatory or fibrotic interstitial lung disease (ILD). METHODS: Our study is a preliminary analysis of a larger prospective cohort. The MRI images of 18 patients with ILD (13 females; mean age, 65 years) were acquired in a 1.5 T scanner and included axial fat-saturated T2-weighted (T2-WI, n = 18) and coronal fat-saturated T1-weighted images before and 1, 3, 5, and 10 minutes after gadolinium administration (n = 16). The MRI studies were evaluated with 2 different methods: a qualitative evaluation (visual assessment and measurement of few regions of interest; evaluations were performed independently by 5 radiologists and 3 times by 1 radiologist) and a segmentation-based analysis with software extraction of signal intensity values (evaluations were performed independently by 2 radiologists and twice by 1 radiologist). Interstitial lung disease was classified as inflammatory or fibrotic, based on previously described imaging criteria. RESULTS: Regarding the qualitative evaluation, intraobserver agreement was excellent (κ = 0.92, P < 0.05) for T2-WI and fair (κ = 0.29, P < 0.05) for T1 dynamic study, while interobserver agreement was moderate (κ = 0.56, P < 0.05) and poor (κ = 0.11, P = 0.18), respectively. In contrast, upon segmentation-based analysis, intraobserver and interobserver agreement were excellent for T2-WI (κ = 0.886, P < 0.001; κ = 1.00, P < 0.001; respectively); for T1-WI, intraobserver agreement was excellent (κ = 0.87, P < 0.05) and interobserver agreement was good (κ = 0.75, P < 0.05). CONCLUSIONS: Segmentation-based MRI analysis is more reproducible than a qualitative evaluation with visual assessment and measurement of few regions of interest.

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.

Lung Magnetic Resonance Imaging for Prediction of Progression in Patients With Nonidiopathic Pulmonary Fibrosis Interstitial Lung Disease: A Pilot Study.

PURPOSE: Correlate magnetic resonance imaging (MRI) parameters at baseline with disease progression in nonidiopathic pulmonary fibrosis interstitial lung disease (ILD). MATERIALS AND METHODS: Prospective observational cohort study, in which patients with non-idiopathic pulmonary fibrosis ILD underwent MRI at baseline (1.5 T). T2-weighted images (T2-WI) were acquired by axial free-breathing respiratory-gated fat-suppressed "periodically rotated overlapping parallel lines with enhanced reconstruction" and T1-weighted images (T1-WI) by coronal end-expiratory breath-hold fat-suppressed "volumetric interpolated breath-hold examination" sequences, before and at time points T1, T3, T5, and T10 minutes after gadolinium administration. After MRI segmentation, signal intensity values were extracted by dedicated software. Percentage of the ILD volume and a ratio between signal intensity of ILD (SIILD) and normal lung (SInormal lung) were calculated for T2-WI; percentage of signal intensity (%SI) at each time point, time to peak enhancement, and percent relative enhancement of ILD in comparison with normal lung (%SIILD/normal lung) were calculated for T1-WI. MRI parameters at baseline were correlated with diagnosis of disease progression and variation in percent predicted forced vital capacity (%FVC) and diffusing capacity of the lung for carbon monoxide after 12 months. RESULTS: Comprehensive MRI evaluation (T2-WI and T1-WI) was performed in 21 of the 25 patients enrolled (68% females; mean age: 62.6 y). Three of the 24 patients who completed follow-up fulfilled criteria for disease progression. Baseline T2-WI SIILD/SInormal lung was higher for the progression group (P = 0.052). T2-WI SIILD/SInormal lung and T1-WI %SIILD/normal lung at T1 were positively correlated with the 12-month variation in %FVC (r = 0.495, P = 0.014 and r = 0.489, P= 0.034, respectively). CONCLUSIONS: Baseline MRI parameters correlate with %FVC decline after 12 months.

Urinary continence recovery after Retzius-sparing robot-assisted radical prostatectomy in relation to surgeon experience.

Urinary incontinence is one of the main concerns for patients after radical prostatectomy. Differences in surgical experience among surgeons could partly explain the wide range of frequencies observed. Our aim was to evaluate the association between the surgeons` experience and center caseload with relation to urinary continence recovery after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). Prospective observational single-center study. Five surgeons consecutively operated 405 patients between July 2017 and February 2022. Continence recovery was evaluated with pad count and by employing the short form of the International Consultation on Incontinence Questionnaire (ICIQ-SF), pre- and postoperatively at 1 year. Non-parametric tests were used. Median age was 63 years, 30% of patients presented with local advanced disease; the positive surgical margin rate (over 3 mm length) was 16%. Complication rate was 1% (Clavien-Dindo > II). One year after surgery, continence was assessed in 282 patients, of whom 87% were pad free and 51% never leaked (ICIQ-SF = 0). With respect to the mean annual number of procedures per surgeon, divided in < 20, 20-39 and ≥ 40, pad-free rates were achieved in 93%, 85%, and 84% and absence of urine leak rates in 47%, 62% and 48% of patients, respectively. Postoperative median ICIQ-SF was five. We acknowledge the limitation of a 12-month follow-up and the fact that we are a medium-volume center. There is no statistically significant association between continence recovery, surgeon's experience and center caseload. Continence recovery at 1 year after surgery is adequate and robust to surgeon's experience.

Confirmation of Groundnut ringspot orthotospovirus (GRSV) Infection in Eggplant Cultivars in Brazil.

Eggplant (Solanum melongena L.) is an economically important vegetable crop in Brazil, especially in family-based farming. Eggplant hybrids 'Ciça' and 'Napoli' (≈ 400 plants) were detected exhibiting virus-like symptoms (5-20% incidence) in field surveys (2015-2018) in Brasília-DF (Figure 1). Symptoms included chlorosis, mosaic and apical leaf deformation. Six symptomatic leaf samples were collected from fruit-bearing plants (around 100 days after planting) aiming at verifying the potential orthotospovirus infection. Double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was carried out with polyclonal antibodies (produced at Centro Nacional de Pesquisa de Hortaliças - CNPH) against the N gene coat protein of the three major orthotospoviruses: tomato spotted wilt orthotospovirus (TSWV), groundnut ringspot orthotospovirus (GRSV) and, tomato chlorotic spot orthotospovirus (TCSV). Strong serological reactions were observed only against GRSV antibodies in the extracts from symptomatic samples, but not in the controls. To confirm the causal agent of those symptoms, total RNA was extracted from infected leaf samples via the standard Trizol® (Sigma) protocol and subsequently used in a two-step reverse transcriptase polymerase chain reaction (RT-PCR) approach. Synthesis of the cDNA was carried out with the J13 primer (5'-CCC GGA TCC AGA GCA AT-3') (Cortez et al., 2001) followed by PCR assays with the primer pair BR60 (5'-AGA GCA ATC GTG TCA-3`) and BR65 (5`-ATC AAG CCT TCT GAA AGT CAT-3') (Eiras et al., 2002). This primer set amplifies a fragment of 453 bp including the 3' untranslated region at the 3' terminus of the S RNA and the protein N-coding gene of at least five species: TSWV, GRSV, TCSV, chrysanthemum stem necrosis orthotospovirus (CSNV) and zucchini lethal chlorosis orthotospovirus (ZLCV). In addition, GRSV-specific primers (LNA Reis, unpublished) were used for amplification of all three segments: L segment: LF/LR (5'-AAC AGG ATT CAG CAA TAT GG-3'/ 5'-AAT TCC TTG AAG ACA ATT GTG T -3'); M segment: MF/MR (5'-TTT GTC CAA CCA TAC CAG ACC C- 3' / 5'-GGC TTC AAT AAA GGC TTG GG-3') and, S segment: SF/SR (5'-TTC AAA CTC AGT TGT ACT CTG A-3'/5'-TTA CTT TCG ATC TGG TTG AA- 3'). Amplicons with 509 bp (MT043204), 289 bp (MT043205), and 901 bp (MT043203) were obtained for L, M and S segments of the eggplant isolate DF-687. PCR amplicons corresponding to a segment of the N-coding gene (396 bp) of a second eggplant isolate (BJL02; MK176337) were obtained with the primer pair BR60/BR65 and subjected to Sanger dideoxy sequencing at CNPH. Alignments of nucleotide sequences of both isolates revealed identity levels varying around 99% to the corresponding genomic regions of a large set of GRSV isolates from GenBank database. PCR assays using total RNA as template yielded 494 bp amplicons solely with GRSV-specific primers (Webster et al., 2011), but no products were obtained with TSWV-specific primers (Adkins and Rosskopf, 2002), confirming the former as the sole causal agent of the field symptoms. Leaves of eggplant cv. 'Ciça' and indicator hosts, including Nicotiana rustica, Capsicum chinense 'PI 159236' (with the Tsw gene), and S. lycopersicum cv. Santa Clara were rub inoculated with extracts prepared from eggplant samples naturally infected with GRSV. Mosaic, necrotic ringspots and systemic leaf deformation symptoms were observed around ten days after inoculation on newly emerged leaves of all inoculated plants. GRSV infection was confirmed by DAS-ELISA and RT-PCR ten days after inoculation. Eggplant was erroneously listed as a host of GRSV in Brazil (Kitajima, 2020). Hence, this is the first report of eggplant infection by this virus in South America. No significant yield losses have been observed in eggplant due to GRSV infection since the overall symptoms are often mild. However, this natural host of GRSV might impact disease management strategies since eggplant is quite often cultivated under family-based farming conditions as a companion crop of highly susceptible tomato, sweet-pepper, and lettuce cultivars.

Behaviour of Escherichia coli O157:H7 and Listeria monocytogenes in Normal and DFD Beef of an Autochthonous Portuguese Breed.

This study was carried out to identify the behaviour of Escherichia coli O157:H7 and of Listeria monocytogenes inoculated in Maronesa breed beef with different ultimate pH (pHu) (Normal and DFD), and stored at two different temperatures (4 and 9 °C), during 28 days post mortem (pm). The main objective was to illustrate the problematic feature of dealing with beef showing high pHu and stored at mild abusive temperatures (9 °C). Beef steaks (ms. longissimus dorsi) were inoculated with low levels (2-3 log CFU/g) of those both pathogens and packed in air, vacuum and three gaseous mixtures with decreasing O2 and increasing CO2 concentrations (MAP70/20, MAP50/40 and MAP30/60). At 4 °C, the growth of E. coli O157:H7 presented the same pattern on Normal and DFD meat. On the contrary, the growth of L. monocytogenes was higher in DFD meat, revealing the effect of the pHu and its psychotropic character. At abusive temperatures, both pathogens grew, achieving high levels in DFD meat. In these cases, the MAP with the highest CO2 concentration (60%) was revealed to be more effective against the development of E. coli O157:H7, therefore, not exceeding levels of 5 log CFU/g at the end of storage, while in L. monocytogenes, it reaches 8 log CFU/g under the same conditions.

A comprehensive diagnostic approach in suspected neurosarcoidosis.

Neurosarcoidosis presents a diagnostic challenge in clinical settings, as it has no pathognomonic symptoms or signs and a wide range of differential diagnoses. The aim of this report is to present the pathological features of our group of patients, obtained through a systematic diagnostic approach. This retrospective cohort study enrolled all adult patients primarily diagnosed with neurosarcoidosis at the neurology department of a tertiary center in Sweden over a period of 30 years, from 1990 to 2021. We identified 90 patients, 54 with possible neurosarcoidosis and 36 with probable neurosarcoidosis. CNS biopsy revealed an alternative diagnosis for 24 patients, who were then excluded. The collected data from medical records included demographic and clinical characteristics, systemic and/or neurological isolated involvement, various laboratory tests, including cerebrospinal fluid (CSF), serum analysis, imaging studies (MRI, FDG-PET/CT, and HRCT), nerve conduction studies, electromyography, and pathology reports of central nervous system (CNS), and extra-neural tissue biopsies. Sixty-six patients were included in our cohort. The median age at onset of symptoms was 49 years, with a similar sex distribution. Cranial neuropathies (38%), motor deficit (32%), headache (16%), and pituitary dysfunction (12%) were the most common presenting features. CSF studies were abnormal in 77% of the patients, who showed lymphocytosis (57%), elevated protein (44%), oligoclonal bands (40%), elevated ACE (28%), and raised T lymphocyte CD4+/CD8+ ratios (13%). Strikingly, MRI showed that 17% of the patients presented with isolated pituitary gland lesions. FDG-PET/CT was performed in 22 patients (33%) and confirmed systemic sarcoidosis in 11. Despite our extensive workup, the final classification for our patients only allowed for a definite diagnosis in 14 patients; the remainder were classified as probable (32) or possible (20) neurosarcoidosis. Since 2007, the employment of a structured laboratory and imaging approach and the increasing number of CNS biopsies have facilitated and improved the process of correct attribution in patients with presumptive neurosarcoidosis, especially in patients with isolated neurological lesions. We highlight a higher frequency of pituitary lesions due to neurosarcoidosis than has been classically described. A detailed laboratory diagnostic workup is included.

Seropositivity for Coxiella burnetii in Wild Boar (Sus scrofa) and Red Deer (Cervus elaphus) in Portugal.

Q fever is caused by the pathogen Coxiella burnetii and is a zoonosis that naturally infects goats, sheep, and cats, but can also infect humans, birds, reptiles, or arthropods. A survey was conducted for the detection of antibodies against C. burnetii in a sample of 617 free-ranging wild ruminants, 358 wild boar (Sus scrofa) and 259 red deer (Cervus elaphus), in east-central Portugal during the 2016-2022 hunting seasons. Only adult animals were sampled in this study. Antibodies specific to C. burnetii were detected using a commercial enzyme-linked immunosorbent assay (ELISA; IDVet®, Montpellier, France) according to the manufacturer's instructions. The seroprevalence of C. burnetii infection was 1.5% (n = 9; 95% confidence interval [CI]: 0.7-2.8%). Antibodies against C. burnetii were detected in 4/358 wild boar (1.1%; 95% CI: CI: 0.3-2.8%) and 5/259 red deer (1.9%; 0.6-4.5%). Results of the present study indicate that antibodies against C. burnetii were present in wild boar and red deer in Portugal. These findings can help local health authorities to focus on the problem of C. burnetii in wildlife and facilitate the application of a One Health approach to its prevention and control.

Retzius-sparing robot-assisted radical prostatectomy in a medium size oncological center holds adequate oncological and functional outcomes.

Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) has emerged as a surgical option for patients with prostatic cancer in high-volume centers. The objective is to assess oncological and functional outcomes when implementing RS-RARP in a medium-volume center without previous experience of robotic surgery. This is a prospective observational single-center study. Patients operated between July 2017 and April 2020 were divided into two consecutive groups, A and B, each with 104 patients. The surgeons had prior experience in laparoscopic surgery and underwent robotic training. Positive surgical margin (PSM) status, urinary continence, and erectile function projected by Kaplan-Meier curves, together with patient reported quality of life outcomes at 12 months post-surgery were documented. Median patient age was 63 years (IQR = 59-67), overall PSM rate were 33%, 28% for pT2 disease. Pre-operative values showed no significant difference between both groups. The rate of urinary continence dropped from 81 to 78% (SE = 5.7) (Group A) and from 90 to 72% (SE = 6.3) (Group B) using the International Consultation on Incontinence Questionnaire-Short Form. Baseline sexual function was regained in 41% (Group A) and 47% (Group B) of patients. The median Expanded Prostate Index Composite-26 total score decreased from 86 to 82. These outcomes relate favorably to prior reports. There was a clinically significant decrease in median operative time in the successive groups with post-operative complications occurring in less than 2% of surgical procedures overall. A 12-month follow-up suggests that RS-RARP may be safely introduced in a medium-volume center without previous experience of robotic surgery.

Primary Anti-Phospholipid Antibody Syndrome: Real-World Defining Features of Rethrombosis in the Course of Disease.

Objective: We aimed to identify features that allow differentiation of primary antiphospholipid syndrome (PAPS) patients that suffer recurrent thrombotic events (RTE) despite anticoagulation, from the other diagnosed PAPS patients. Methods: This was an exploratory study of anticoagulated PAPS patients attending an Autoimmune Diseases Unit (1998-2018). From 2016, anti-phospholipid antibodies and lupus anticoagulant were determined for each patient at consecutive visits, collected together with retrospective clinical characteristics, laboratory, and therapeutic markers and compared according to the occurrence of thrombotic events during follow-up. Results: Overall, two thirds of the patients were female, 93% were Caucasian, with a median age of 40 years at diagnosis, for a median time of 11.5 years in follow-up. Out of 54 patients, 10 were identified with RTE. There were no significant differences among the RTE and non-RTE patients as far as classical risk factors for clotting disorders. The RTE group was characterized by a higher proportion of younger patients, male sex and positivity for all laboratory markers, and initially and over follow-up as well as a sustained high-risk profile based on APS laboratory markers. Anticardiolipin IgG at onset was the only statistically significant marker of the RTE group. At the end of follow-up, consistent reversion to negative status was a rare event, observed in 20% of RTE vs. 25% of non-RTE patients. Conclusions: Despite therapy, we were able to identify features associated to thrombotic events in patients with PAPS. Prospectively regular clinical and laboratory monitoring might be warranted in order to treat APS more assertively.

A Challenging Case of Eyelid Ptosis and Diplopia Induced by Pembrolizumab.

We present the case of an 83-year-old female patient with gastric adenocarcinoma, who developed a subacute onset of eyelid ptosis and ophthalmoparesis, while being treated with pembrolizumab, raising the suspicion of myasthenia gravis. Workup exposed a broader systemic involvement, with liver, cardiac and skeletal muscle being affected as well. Further investigation lead us to change our initial diagnosis to multisystem inflammatory syndrome with isolated symptomatic ocular myositis, induced by pembrolizumab. High-dose steroids and immunoglobulin were started with a good outcome.

A Cross-Sectional Study of Knowledge on Ownership, Zoonoses and Practices among Pet Owners in Northern Portugal.

Pet ownership is common in modern society. In Portugal, 38% and 31% of all households own at least one dog or cat, respectively. Few studies have ascertained the knowledge of pet owners on pet ownership and zoonoses, and none have been carried out in Portugal. The aim of the present study was to assess household knowledge and practices related to pet ownership and zoonoses in northern Portugal. A face-to-face questionnaire was completed by 424 pet owners, from November 2019 to February 2020. Most respondents (97.2%) considered pets as an important part of the family, especially women (p = 0.036); 73.1% allowed their pets to live an indoor/outdoor life; 41.3% denied sharing the bed with their pets while 29% assumed they did it daily; 20.3% reported never kissing their pets/pets licking their faces. Furthermore, 73.6% considered animals as potential sources of human diseases, but only 25.9% reported knowing the definition of zoonoses; 96.9% considered the role of veterinarians important in protecting public health. The low level of knowledge of pet owners and the occurrence of high-risk behaviors indicates a need to strengthen communication between veterinarians, physicians, pet owners, and the general public towards reduce the risk of acquisition and transmission of zoonoses.

Food Waste and Qualitative Evaluation of Menus in Public University Canteens-Challenges and Opportunities.

BACKGROUND: This study aims to evaluate food waste and menu quality in two canteens (A and B) from a Portuguese public university in order to identify challenges and opportunities to improve the food service. METHODS: Food waste included the analysis of two canteens over 5 consecutive days by selective aggregate weighing. A qualitative evaluation of a 5-week menu cycle related to lunches was performed through the Qualitative Evaluation of Menus (AQE-d) method. RESULTS: Both menus have "satisfactory" evaluations and lower adequacy to the dietary guidelines in criteria A, which evaluates general items from the dish, and in criteria B, which evaluates meat, fish and eggs. The calculated mean of food waste in both canteens exceeded the acceptable limit of 10%, except for the vegetarian (7.5%) dish in canteen A. The biggest waste was found in the vegetarian dish (16.8%) in canteen A. In meat dishes the conduit presents more waste (17.0%) than in fish and vegetarian dishes. Among these, the vegetables were the most wasted (25.3% and 27.9%, respectively). CONCLUSION: This work presents some insights to future interventions in the direction of a healthier and more sustainable foodservice.

Biological Therapy in Patients with Rheumatoid Arthritis in a Tertiary Center in Portugal: A Cross-Sectional Study.

INTRODUCTION: Clinical outcomes in rheumatoid arthritis have greatly improved with therapeutic advances. Despite the availability of substantial clinical trial evidence, there is a lack of real-life data. The aim of this study was to assess disease status and quality of life in an outpatient population treated with biological disease-modifying anti-rheumatic drugs. MATERIAL AND METHODS: Cross-sectional study recalling all patients ever treated in our unit with biological disease-modifying antirheumatic drugs. Clinical and demographic data, compliance, disease activity, functional status, joint deformities, and comorbidities were documented, and patients queried on occupational status, education, marital status and generic health related quality of life questionnaires. RESULTS: Recall was attended by 77 of the original 94 patients. At recall, median age was 63 years old, 82% of the patients were female and the median disease duration was 12 years. Biological therapy was started at a median of four years following disease onset. According to the disease activity score (DAS28), the percentage of patients with high, moderate, low disease activity or remission changed from 50, 45, 0 and 5 (pre-therapy) to 11, 37, 25 and 26 at recall, respectively; functional status was significantly improved. Seventy-five per cent of the patients retained the original treatment with good compliance. Lower Short Form-36 domain scores accompanied a low EQ-5D-3L score. Deceased patients (n = 6) had a lower estimated 10-year survival rate. In this group, biological therapy was discontinued at a higher frequency during follow-up. DISCUSSION: A high disease activity and a high HAQ disability index characterized most patients at pre-bDMARD onset. CONCLUSION: Despite therapy switches and regular follow-up, a significant percentage of patients still presented with moderate disease activity, functional impairment and a poor health-related quality of life.

Introdução: Avanços no tratamento da artrite reumatóide contribuiram para uma evolução favorável. Apesar de evidências substanciais provenientes de ensaios clínicos, são menos conhecidos os dados provenientes da vida real. O objetivo do estudo foi caracterizar a doença e a qualidade de vida em doentes sob fármacos biotecnológicos. Material e Métodos: Trata-se de um estudo transversal com recolha de dados clínicos relativos à adesão terapêutica, atividade da doença, capacidade funcional, deformidades articulares, comorbilidades e questionários de qualidade de vida relacionada com a saúde, estado civil, situação profissional e escolaridade. Resultados: Foram recrutados 77 doentes do grupo original de um total de 94. A mediana da idade foi 63 anos, 82% do sexo feminino e início de biológico cerca de quatro anos após o início da doença, com uma mediana de duração de 12 anos. De acordo com o disease activity score (DAS28), a percentagem de doentes com atividade alta, moderada, baixa ou em remissão mudou, respectivamente, de 50, 45, 0 e 5 pré- biológico para 11, 37, 25 e 26 na altura da re-avaliação, com melhoria funcional. Setenta e cinco por cento dos doentes mantiveram o tratamento original com boa adesão. Pontuações mais baixas do short form-36 associaram-se a uma baixa pontuação no EQ-5D-3L. No grupo de doentes que viriam a falecer (n = 6), foi observada uma menor esperança de vida aos 10 anos, assim como uma maior discontinuação da terapêutica biológica. Discussão: Pré-biológico, uma elevada percentagem dos doentes apresentava elevada atividade da doença e incapacidade funcional. Conclusão: Não obstante ajustes terapêuticos e seguimento regular, uma percentagem significativa de doentes mantinha atividade moderada e limitação funcional com baixa qualidade de vida relacionada com a saúde.

Bats, pangolins, minks and other animals - villains or victims of SARS-CoV-2?

Coronavirus disease-19 (COVID-19) is caused by the severe acute Respiratory syndrome coronavirus-2 (SARS-CoV-2), which has become unstoppable, spreading rapidly worldwide and, consequently, reaching a pandemic level. This review aims to provide the information available so far on the likely animal origin of SARS-CoV-2 and its possible hosts/reservoirs as well as all natural animal infections and experimental evidence using animal models. Horseshoe bats from the species Rhinolophus affinis seem to be a natural reservoir and pangolins (Manis javanica) appear to be an intermediate host of SARS-CoV-2. Humans remain the most likely spreading source of SARS-CoV-2 to other humans and also to domestic, zoo and farm animals. Indeed, human-to-animal transmission has been reported in cats, dogs, tigers, lions, a puma and minks. Animal-to-human transmission is not a sustained pathway, although mink-to-human transmission remains to be elucidated. Through experimental infections, other animals seem also to be susceptible hosts for SARS-CoV-2, namely ferrets, some non-human primate species, hamsters and transgenic mice, while dogs, pigs and poultry are resistant. A One Health perspective must be implemented in order to develop epidemiological surveillance and establish disease control mechanisms to limit zoonotic transmission. Moreover, research in this field is important to better understand SARS-CoV-2 and to obtain the long-awaited vaccine and specific treatment.

Post-partum depression: a cross-sectional study of women enrolled in a conditional cash transfer program in 30 Brazilian cities.

OBJECTIVE: Investigate factors associated with symptoms of postpartum depression in mothers from families in social vulnerability. METHODS: Information was used from the baseline of a randomized trial to assess a child development program that enrolled 3,242 children < 12 months of age from beneficiary families of the Bolsa Família Program residing in 30 municipalities (counties) in six states of Brazil. The Edinburgh Postnatal Depression Scale (EPDS) was applied to the mothers, and depression was defined as score ≥10. Information on the mother (schooling, age, parity, marital status, skin color, smoking, number of prenatal appointments, and planning of the pregnancy), family (paternal schooling, household crowding, support from the child's father and the family during the pregnancy, and number of children under 7 years living in the household), and infant (sex, gestational age, birthweight, Apgar score, and child's age at the time of the interview) was collected. Prevalence rates for depressive symptoms were calculated with crude and adjusted odds ratios (OR) and 95% confidence intervals (95%CI), using hierarchical logistic regression, in a multilevel model. RESULTS: The analysis included 3,174 mothers with information on EPDS. The interviews were conducted on average 7.9 months (standard deviation= 2.9) after childbirth. Overall prevalence of depressive symptoms was 26.5% (25.0-28.1%). In the adjusted analysis, higher parity was associated with higher odds of postpartum depression (p <0.001). Women with ≥3 previous deliveries showed an odds 84% higher of presenting depressive symptoms (OR= 1.84; 1.43-2.35) than primiparae. Higher maternal and paternal schooling, presence of husband or partner, and having received support from the child's father and the family during the pregnancy were protective factors against postpartum depression. CONCLUSION: The study showed high prevalence of postpartum depressive symptoms. Promotion of parental education, alongside with the promotion of support to the woman during pregnancy by the child's father and by the family, as well as family planning leading to birth spacing are measures that may help to prevent postpartum depressive symptoms.
