Tuberculin skin test repetition after TNF-α inhibitors in patients with chronic inflammatory arthritis: a long-term retrospective cohort in endemic area.

OBJECTIVES: To evaluate the tuberculin skin test (TST) conversion in chronic inflammatory arthropathies (CIA) patients on TNFα inhibitors (TNFi) and without previous latent tuberculosis infection (LTBI) treatment. METHODS: Patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) with negative LTBI were retrospectively evaluated for TST conversion and active tuberculosis (TB) after six months of exposition to TNFi. Two groups were compared: patients who repeated TST (TST-repetition) during the follow-up and patients who did not (non-TST-repetition). RESULTS: A total of 355 CIA patients on TNFi were screened and 138 (38.9%) did not fulfill the inclusion criteria. Of the remaining 217 CIA patients, 81 (37.3%) repeated TST during TNFi treatment. TST conversion rate was observed in 18 (22.2%) patients without significant differences among CIA (p = 0.578). The number of TB cases was low (n = 10; 4.6%) and was similar in TST-repetition and non-TST-repetition groups [2 (2.5%) vs. 8 (5.9%), p = 0.328]. Of note, 30% of active TB occurred early (6-12 months of TNFi exposure) and the median (full range) time to incident TB was 1.3 (0.6-10.6) years, whereas the median (full range) time to TST repetition was later [3.3 (0.5-13.4) years]. The incidence of active TB was lower among RA patients than AS patients [342 (95% CI 41 - 1446) vs. 1.454 (95% CI 594-2993)/100,000 patient-years, p = 0.049]. CONCLUSION: These results indicate that TST repetition is associated with a high conversion rate, suggesting the need for recommended treatment. The delayed repetition of TST and low number of active TB cases hampered the evaluation of this strategy effectiveness to prevent active infection. Larger studies with systematic repetition patterns are necessary. In addition, the study highlights the need for a greater surveillance for TB in AS patients.

Extraction, characterization and properties evaluation of pineapple leaf fibers from Azores pineapple.

Pineapple leaves can provide competitive and high-quality fibers for textile purposes. Despite pineapple being cultivated in the Portugues islands there is still a technology gap for the extraction and treatment of Pineapple Leaf Fibers (PALF) in Europe. Since Azorean Pineapple differs significantly from other plants in the bromeliad family, the properties and characterization of its leaf fibers were explored for the first time. Long fibers have been extracted by hand scraping and compared to biological retting at 25 °C for different time periods. It was explored the properties of PALF from plants of different ages (11- and 18-months) and from different zones of the leaves (beginning, middle, and tip). Physical-mechanical properties of Azores PALF were determined, including diameter, linear density, strength, Young's modulus, and elongation at break and characterized by ATR-FTIR, XRD, TGA/DTG, and FESEM to understand their chemical and morphological characteristics. While slight differences were observed between different ages, variations in physical-mechanical properties were notable among fibers extracted from different leaf positions. Extraction of Azores PALF through 25 °C biological retting for 14 days effectively eliminated non-fibrous matter and produced the thinnest and strongest fibers. These fibers ranged between 34.9 and 168.3 µm in diameter, 1.39 and 7.07 tex in linear mass density, 37-993 MPa in tensile strength, 1.0-3.9 % in elongation at break, and 2.4-21.8 GPa in Young's modulus.

Breast cancer in young women: a rising threat: A 5-year follow-up comparative study.

Introduction: Breast cancer in young women is usually considered as breast cancer occurring in women younger than 40 years and is the most frequent cancer-related cause of death in these patients. In the past few years, there seems to be an increasing trend in the prevalence of breast cancer in young women, which, associated with poorer prognosis, more aggressive histologic features, and more frequent recurrence rates, makes it a rising threat to young women. This study aimed to evaluate the biological behavior of breast cancer in young women in our institution. Material and methods: A retrospective, unicentric, cohort study was conducted between 2012 and 2016. All consecutive patients with breast cancer were enrolled in the study. Cases were divided into two groups: case group, those younger than 40 years, and control group, those 40 years or older. The exclusion criterion was nonoperative treatment. Several clinical and pathologic parameters were evaluated, as well as were overall survival time and disease-free survival time. Results: The incidence of breast cancer in young women presented a rising tendency over the study period. Significant differences were observed in the comparison of the groups according to body mass index, age at menarche, age at birth of the first child, and proliferation rate. There were no differences in overall survival and disease-free survival rates between the groups. Conclusions: Young women had a more symptomatic presentation, a greater tumor proliferation rate, but similar outcomes compared with older patients. Greater multicentric studies are needed to confirm or refute these results.

Handlebar hernia-unusual complication from blunt trauma.

Handlebar hernia is a rare entity, mainly resulting from blunt abdominal trauma with a sudden deceleration mechanism. Diagnosis of handlebar at admission may be difficult because the rupture of abdominal wall layers often is not clinically recognized in the emergency department, which requires a high degree of suspicion to identify theses lesions. It is very important to rule out the presence of intra-abdominal injuries, and in adults, surgical repair is needed. Herein, the case of an adult man who presented to the emergency department with blunt abdominal trauma caused by a motorcycle handlebar is described.

Dietetic intervention in psoriatic arthritis: the DIETA trial.

AIM: To evaluate whether dietary pattern changes, antioxidant supplementation or 5-10% weight loss could improve disease activity (skin and joint) in patients with psoriatic arthritis (PsA). METHODS: A total of 97 PsA patients were enrolled in this 12-week randomized, double-blinded, placebo-controlled trial. Patients were randomized into three groups: Diet-placebo (hypocaloric diet + placebo supplementation); Diet-fish (hypocaloric diet + 3 g/day of omega-3 supplementation; and Placebo. Food intake (3-day registry, Healthy Eating Index (HEI), and the Dietary Inflammatory Index (DII)), body composition (whole-body dual-energy X-ray absorptiometry (DXA), weight and waist circumference) and disease activity (PASI, BSA, BASDAI, DAS28-ESR, DAS28-CRP and MDA) were evaluated at baseline and after the 12-week intervention. Statistical analysis used the intention-to-treat approach. The P value was considered to indicate significance when below 0.05. RESULTS: After 12 weeks, DAS28-CRP and BASDAI scores improved, especially in the Diet-placebo group (- 0.6 ± 0.9; p = 0.004 and - 1.39 ± 1.97; p = 0.001, respectively). In addition, a higher proportion of patients achieved minimal disease activity (MDA) in all groups. The Diet-fish group showed significant weight loss (- 1.79 ± 2.4; p = 0.004), as well as waist circumference (- 3.28 ± 3.5, p < 0.001) and body fat (- 1.2 ± 2.2, p = 0.006) reductions. There was no significant correlation between weight loss and disease activity improvement. Each 1-unit increase in the HEI value reduced the likelihood of achieving remission by 4%. Additionally, each 100-cal daily intake increase caused a 3.4-fold DAS28-ESR impairment. CONCLUSION: A 12-week hypocaloric intervention provided suitable control of joint disease activity in patients with PsA, regardless of weight loss. Adding omega-3 supplementation caused relevant body composition changes but not disease activity improvement. TRIAL REGISTRATION: The study was recorded on Clinicaltrials.gov (NCT03142503).

Assessment of the Financial Capacity in the Context of Normal and Pathological Cognitive Aging. Preliminary Analysis of the Portuguese Version of the Numerical Activities of Daily- Living- Financial (NADL-F).

Financial capacity (FC) is conceptualized as a dimension that encompasses a wide range of basic aptitudes and the capacity to judge and assess situations and make decisions according to one best interests. The Numerical Activities of Daily-Living-Financial (NADL-F) is an instrument of FC for clinical use developed in Italy. This study aims to perform a preliminary analysis on the psychometric characteristics of the Portuguese version of NADL-F. NADL-F as well as other neuropsychological instruments were administered to three groups: Healthy Control (n = 11); Mild Neurocognitive Disorder group (n = 19); Major Neurocognitive Disorder group (n = 19). NADL-F and its tasks were considered acceptable, showed good reliability for the entire sample (α = .808) and the majority of the domains correlated significantly with each other and with the total scale. Between group comparisons showed significant differences regarding all domains. Arithmetic, schooling and executive functioning accounted for 54.1% of the variance on the test. The Portuguese version of NADL-F proved to be an acceptable and valid instrument of assessing FC in the context of cognitive aging. NADL-F is an instrument that emulates real life financial situations, and it can be used in a second level of evidence in the clinical model of FC assessment.

Performance of 4 methods for screening of latent tuberculosis infection in patients with chronic inflammatory arthritis under TNFα inhibitors: a 24-month prospective study.

BACKGROUND: The reactivation rate of tuberculosis in patients with chronic inflammatory arthritis (CIA) on TNFα inhibitors (TNFi) and baseline negative screening for latent tuberculosis infection (LTBI) is higher than in the general population. AIM: To compare the performance of tuberculin skin test (TST), TST-Booster, ELISPOT (T-SPOT.TB) and QuantiFERON-TB Gold in tube (QFT-IT) to detect LTBI in patients with CIA on TNFi. PATIENTS AND METHODS: A total of 102 patients with CIA [rheumatoid arthritis (RA), n = 40; ankylosing spondylitis (AS), n = 35; psoriatic arthritis (PsA), n = 7; and juvenile idiopathic arthritis (JIA), n = 20] were prospectively followed-up for 24 months to identify incident LTBI cases. Epidemiologic data, TST, T-SPOT.TB, QFT-IT and a chest X-ray were performed at baseline and after 6 months of LTBI treatment. RESULTS: Thirty six percent (37/102) of patients had positive TST or Interferon Gamma Release Assays (IGRAs) tests. Agreement among TST and IGRAs was moderate (k = 0.475; p = 0.001), but high between T-SPOT.TB and QFT-IT (k = 0.785; p < 0.001). During the 24-Month follow-up, 15 (18.5%) incident cases of LTBI were identified. In comparison to TST, the IGRAs increased the LTBI diagnosis power in 8.5% (95% CI 3.16-17.49). TST-Booster did not add any value in patients with negative TST at baseline. After 6-Month isoniazid therapy, IGRAs results did not change significantly. CONCLUSIONS: Almost 20% of CIA patients had some evidence of LTBI, suggesting higher conversion rate after exposition to TNFi. TST was effective in identifying new cases of LTBI, but IGRAs added diagnostic power in this scenario. Our findings did not support the repetition of IGRAs after 6-Month isoniazid therapy and this approach was effective to mitigate active TB in 2 years of follow-up.

Poly(Lactic Acid)/Graphite Nanoplatelet Nanocomposite Filaments for Ligament Scaffolds.

The anterior cruciate ligament (ACL) is one of the most prone to injury in the human body. Due to its insufficient vascularization and low regenerative capacity, surgery is often required when it is ruptured. Most of the current tissue engineering (TE) strategies are based on scaffolds produced with fibers due to the natural ligament's fibrous structure. In the present work, composite filaments based on poly(L-lactic acid) (PLA) reinforced with graphite nanoplatelets (PLA+EG) as received, chemically functionalized (PLA+f-EG), or functionalized and decorated with silver nanoparticles [PLA+((f-EG)+Ag)] were produced by melt mixing, ensuring good filler dispersion. These filaments were produced with diameters of 0.25 mm and 1.75 mm for textile-engineered and 3D-printed ligament scaffolds, respectively. The resulting composite filaments are thermally stable, and the incorporation of graphite increases the stiffness of the composites and decreases the electrical resistivity, as compared to PLA. None of the filaments suffered significant degradation after 27 days. The composite filaments were processed into 3D scaffolds with finely controlled dimensions and porosity by textile-engineered and additive fabrication techniques, demonstrating their potential for ligament TE applications.

Higher bodily adiposity, fat intake, and cholesterol serum levels are associated with higher disease activity in psoriatic arthritis patients: is there a link among fat and skin and joint involvement?

INTRODUCTION/ OBJECTIVES: Assuming that there is a link between lipid and glucose metabolism and inflammation in patients with psoriatic arthritis (PsA), our aim was to evaluate the relationships among body composition measurements, food intake, and disease activity in patients with PsA. METHODS: A total of 97 patients with PsA, according to the CASPAR criteria, were included in this cross-sectional study. Body composition measurements (whole-body DXA, GE-Lunar), food intake (3-day registry) and biochemical and inflammatory serum markers were evaluated. Skin and joint disease activity were assessed by using PASI, BSA, DAS28, and minimal disease activity (MDA). The level of significance was set as p < 0.05. RESULTS: A higher prevalence of obesity, according to the fat mass index (FMI) (92.7%), and metabolic syndrome (MetS) (54%) were found, but no significant changes regarding lean or bone mass were found. Joint disease activity was positively correlated with total body fat (r = 0.4; p < 0.001), FMI (r = 0.33; p < 0.001), body mass index (r = 0.20; p < 0.049) and waist circumference (r = 0.27; p = 0.009). In addition, joint disease activity was negatively associated with muscle mass (r = - 0.38; p < 0.001). Skin disease activity was positively correlated with total cholesterol (r = 0.3; p = 0.003) and LDL-cholesterol (r = 0.28; p = 0.006). After multiple adjustments, patients with severe joint disease activity had higher body adiposity than patients in remission or with low disease activity. Skin disease activity was associated with higher trans-fat intake and lower omega-6 consumption. CONCLUSIONS: Our data suggest a possible harmful link among fat (body adiposity, saturated fat consumption, LDL-cholesterol serum levels) and joint and skin disease activity in patients with PsA.

Pseudomyxoma peritonei presenting as irreducible epigastric hernia.

Abdominal wall hernia is a common and usually straightforward pathology presenting in surgery clinics. On occasion, the surgeon is faced with unexpected findings requiring difficult intraoperative decision. We present a case of pseudomyxoma peritonei incidentally found during surgery for epigastric hernia. The patient complained of a long lasting epigastric hernia with recent onset pain and growth. Surgery was limited to laparoscopic incisional biopsy of mucinous peritoneal deposit, confirming the diagnosis and suggesting an appendiceal origin. The patient was subsequently referred to a specialized peritoneal cancer unit for definitive treatment which consisted of cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy, which can be compromised by previous organ resection. This case highlights the importance of maintaining a high level of suspicion before unusual clinical courses of common pathology.

Heterotopic mesenteric and abdominal wall ossification - Two case reports in one institution.

INTRODUCTION: Heterotopic ossification occurs when bone develops in tissues which usually don't undergo ossification. Heterotopic mesenteric ossification, also known as intra-abdominal myositis ossificans, is a rare and benign form of ossification, usually related with previous abdominal surgery or trauma. PRESENTATION OF CASES: We report two cases of heterotopic ossification both after multiple abdominal surgeries, with intraoperative findings of mesenteric and abdominal wall ossification. Histopathology revealed metaplastic bone deposition, without evidence of atypia or malignancy. DISCUSSION: This rare entity shares clinical and pathological characteristics of myositis ossificans. It is important to consider the differential diagnosis with sarcomas. In the cases described, the patients were proposed for elective surgery and this pathology was as an incidental finding. CONCLUSION: The simultaneous presence of mesenteric and abdominal wall ossification in both patients makes these cases even rarer.

Incidence of active mycobacterial infections in Brazilian patients with chronic inflammatory arthritis and negative evaluation for latent tuberculosis infection at baseline--a longitudinal analysis after using TNFa blockers.

Several studies point to the increased risk of reactivation of latent tuberculosis infection (LTBI) in patients with chronic inflammatory arthritis (CIAs) after using tumour necrosis factor (TNF)a blockers. To study the incidence of active mycobacterial infections (aMI) in patients starting TNFa blockers, 262 patients were included in this study: 109 with rheumatoid arthritis (RA), 93 with ankylosing spondylitis (AS), 44 with juvenile idiopathic arthritis (JIA) and 16 with psoriatic arthritis (PsA). All patients had indication for anti-TNFa therapy. Epidemiologic and clinical data were evaluated and a simple X-ray and tuberculin skin test (TST) were performed. The control group included 215 healthy individuals. The follow-up was 48 months to identify cases of aMI. TST positivity was higher in patients with AS (37.6%) than in RA (12.8%), PsA (18.8%) and JIA (6.8%) (p < 0.001). In the control group, TST positivity was 32.7%. Nine (3.43%) patients were diagnosed with aMI. The overall incidence rate of aMI was 86.93/100,000 person-years [95% confidence interval (CI) 23.6-217.9] for patients and 35.79/100,000 person-years (95% CI 12.4-69.6) for control group (p < 0.001). All patients who developed aMI had no evidence of LTBI at the baseline evaluation. Patients with CIA starting TNFa blockers and no evidence of LTBI at baseline, particularly with nonreactive TST, may have higher risk of aMI.

Acolhimento do doente no bloco operatório / Welcoming the patient to the operating room

O acolhimento do doente no bloco operatório inicia-se aquando a admissão e prossegue até ao momento da alta, sendo que o enfermeiro tem um papel fundamental e preponderante no bem estar físico e psicológico do doente. Tratando-se de um estudo metodológico, de carácter descritivo-correlacional, analítico, inserido no paradigma da investigação quantitativa, os dados foram obtidos através de questionários numa amostra acidental de 150 doentes, submetidos a cirurgia de catarata em regime de ambulatório no Bloco Operatório de Oftalmologia do CHUCHUC, no período de 1 de Abril a 31 de Julho de 2014, após consentimento informado. Assim, este estudo teve como objeto o tema: O acolhimento do doente submetido a cirurgia de catarata em regime de ambulatório, no Bloco Operatório de Oftalmologia do CHUC-HUC e pretendeu desenvolver e validar uma escala para o estudo metodológico; identificar as ações desenvolvidas pelos enfermeiros no processo do acolhimento; identificar os aspetos valorizados pelos doentes do foro cirúrgico no processo de acolhimento, no Bloco Operatório de Oftalmologia e relacionar a importância atribuída pelos doentes ao acolhimento, com as variáveis de domínio sociodemográfico e clínico, nomeadamente sexo, idade, experiência cirúrgica, cirurgias anteriores, no serviço em estudo. Com este estudo, conclui-se que os enfermeiros no processo do acolhimento do doente, estabelecem ações adequadas, sobretudo no processo de comunicação, estabelecendo uma comunicação eficaz e transmitem informações pertinentes e necessárias no processo de saúde/doença. Outra conclusão que obtivemos, foi que os doentes atribuem importância ao acolhimento efetuado pelo enfermeiro, observam todas as suas ações realizadas nesse processo e atribuem ainda importância ao processo da comunicação e à informação que lhe é transmitida. Em termos globais, tudo é valorizado por eles, aquando a sua permanência no bloco operatório e independentemente das suas condições sociodemográficas.

Posterior ankle impingement syndrome: a diagnosis rheumatologists should not forget. Two case reports.

The ankle is a common site of painful symptoms in athletes and nonathletes. Posterior ankle pain can be the end result of several pathologies, and a diagnostic challenge for rheumatologists. The posterior ankle impingement syndrome, also known as os trigonum syndrome and posterior tibiotalar compression syndrome, is a clinical disorder characterized by acute or chronic posterior ankle pain triggered by forced plantar flexion, which causes chronic repetitive microtrauma. Pathology of the os trigonum-talar process is the most common cause of this syndrome, but there are other causes, such as tenosynovitis of the flexor hallucis longus, ankle osteochondritis, subtalar joint disease, and fracture. Diagnosis is based on clinical history and physical examination, and complemented by findings on plain radiography (RX), ultrasound (US), scintigraphy, computed tomography (CT), and magnetic resonance imaging (MRI). It is worth noting that RX has low cost and good sensitivity, US can provide guidance to therapeutic infiltrations, and MRI allows the assessment of surrounding soft tissues.

Síndrome do impacto posterior do tornozelo: um diagnóstico que deve ser lembrado pelo reumatologista. Relato de dois casos / Posterior ankle impingement syndrome: a diagnosis rheumatologists should not forget. Two case reports

O tornozelo é sítio frequente de sintomas dolorosos em atletas e não atletas. A dor localizada na região posterior pode ser o resultado final de diversas patologias, sendo um desafio diagnóstico para o reumatologista. A síndrome do impacto (pinçamento) posterior do tornozelo, também denominada síndrome os trigonum e síndrome compressiva tibiotalar posterior, é um distúrbio clínico caracterizado por dor aguda ou crônica na região posterior do tornozelo, desencadeada pela flexão plantar forçada, que promove microtrauma crônico repetitivo. A patologia do processo os trigonum-talar é a causa mais comum dessa síndrome, mas existem outras causas, como tenossinovite do flexor longo do hálux, osteocondrite de tornozelo, doença da articulação subtalar e fratura. O diagnóstico baseia-se na história clínica e exame físico, e complementado por achados na radiografia simples (RX), ultrassom (US), cintilografia, tomografia computadorizada (TC) e ressonância magnética (RM). Destacamos o RX por seu baixo custo e boa sensibilidade, o US pela possibilidade de guiar infiltrações terapêuticas e a RM pela possibilidade de avaliar partes moles adjacentes.

[Self-esteem in formal care providers and quality of life indexes in users of support facilities for the institutionalized elderly, in Portalegre]. / Auto conceito em Cuidadores Formais e indices de Qualidade de VIDA em utilizadores de Instituições de apoio a terceira idade em regime de internamento, em Portalegre.

It is a transversal and descriptive study, and the main meaning was to measure the Self-concept of formal caregivers in elderly institutions, and also the life quality of internally users in the same institutions. To the development of the study were selected two of the elderly institutions of Portalegre, Portugal. The population was composed by internally users (N=113) and formal caregivers (N=81) of both elderly institutions, being used respectively the WOHQOL-bref Questionnaire and the Self-concept Inventory (Vaz Serra, 1986). Based on the distribution of the self-concept of formal caregivers by mean point, we verify that 97.67% (n=42) have a high self-concept and 2.33% (n=1) have a low self-concept. We can conclude that generally formal caregivers have a high self-concept. About life quality value, we verify that most of internally users have values above the average point that identify the life quality. That suggests the internally users have a life quality above the medium point.
