Abstract

Urinary tract infections are defined as the presence of microorganisms in any part of the urinary system, with the exception of the distal urethra. A majority of them are uncomplicated infections that are resolved on an outpatient basis, with empirical therapy. The objectives of this work were to study the sociodemographic characteristics of patients, analyze associated strains and examine the response of the main microorganisms to antibiotics. A retrospective observational study of all positive urine cultures between 2018 and 2022 was carried out at an institution (8340 samples). Sociodemographic data were also collected. In total, 61.3% were women, with an average age of 63.4 years, and 43.2% were from the Emergency Department. A total of 13.5% were fitted, 56% of whom were women. Also, 95.9% were not taking any antibiotics, and among the individuals who were taking antibiotics, 50% were injected. Escherichia coli (53.5%) and Klebsiella pneumoniae (13.8%) are identified as the most prevalent strains. In the time periods analyzed, Escherichia coli decreased its resistance to 11 antibiotics and increased to 5 antibiotics, while Klebsiella pneumoniae decreased to 7 and increased to 7, with emphasis on the presence of 3 antibiotics with a resistance rate of 100% to all Klebsiella pneumoniae strains identified in 2022.

Abstract

aim of our study was to characterize the evacuated African patients diagnosed with retinoblastoma and referred to the Portuguese national referral center (Centro Hospital e Universitário de Coimbra, University of Coimbra), identifying inequalities in the stage of diagnosis and prognostic results. Design: Retrospective observational study of evacuated African patients diagnosed with retinoblastoma and referred to the Portuguese National Referral Center (Centro Hospital e Universitário de Coimbra, University of Coimbra). Results: The study included 15 patients between October 2015 and October 2020 from Angola, Cape Verde, Guinea-Bissau and São Tomé and Príncipe. Seven (46.7%) children presented bilateral retinoblastoma. The median age at the time of diagnosis was 20.9 (interquartile range, 16– 41) months. The presenting symptoms were leukocoria (86.7%), strabism (53.3%) and buphthalmus (40%). In terms of tumor staging, five (33.3%) children presented with extraocular retinoblastoma and 10 (66.7%) children presented with intraocular retinoblastoma. At presentation, no pineal involvement was diagnosed but two (13.3%) children presented with central nervous system involvement at the time of the first observation. Children were treated with enucleation, exenteration, systemic chemotherapy, intra-arterial chemotherapy and/or supportive palliative care. During the follow-up period (mean 27.2 ± 18.2 months), the overall survival was 73.3%. Conclusion: A small proportion of African children are being referred to our center, when considering the expected incidence of retinoblastoma in these countries, and referred children arrive at advanced stages of the disease, compromising treatment outcomes. Considering retinoblastoma is now a curable disease, national and international interventions are required to attempt a better management of children born in low-income countries.

Abstract

Background: The prevalence and pathology pattern of iodine deficiency (ID) related disorders are influenced by the dietary iodine intake: low iodine leads to thyroid nodular enlargement, to an increase in the incidence of thyroid cancer, an increase in anaplastic carcinomas and to an alteration in the papillary to follicular neoplasia ratio. This study aims at highlighting the effects of ID by comparatively evaluating the pattern of thyroid nodular pathology in different populations that, although geographically distant and heterogeneous, both had iodine deficiency at the time of data gathering and are at high altitude: Beira Interior (BI) in Portugal and Johannesburg (JHB) in South Africa. (S.A.) Mandatory salt iodization introduced in S. A. in 1995 has recently been shown to have resulted in the correction of ID. Methods: Evaluation of thyroid histology reports over a 6 year period in BI and a 5 year period in the JHB area. Results: Region of BI: 278 patients with histology reports-60 were malignancies (21.2 %): 31 papillary carcinomas, 22 follicular cancers (18 follicular carcinomas and 4 Hürthle cell tumours), 3 medullary carcinomas and 4 anaplastic carcinomas. Region of JHB: 136 histology reports- 33 were malignancies (24.3 %): 13 papillary carcinomas, 15 follicular cancers (10 follicular carcinomas and 5 Hürthle cell tumours), 1 medullary carcinoma, 3 anaplastic carcinomas and 1 metastatic carcinoma into the thyroid. There was an overlap in the frequencies of all histology types, of particular relevance in the relatively high anaplastic carcinoma incidences and in the papillary to follicular carcinoma ratios which was close to 1 in both areas- BI area ratio: 1.4 and JHB area ratio: 0.87, with overlapping 95 % CI's, also confirmed by the results of the chi-square calculations. Conclusions: During the study periods evaluated both study areas displayed pathology patterns usually found in ID. Public information regarding the negative consequences of ID combined with the availability of affordable iodized salt are likely to achieve the goal of the elimination of ID. Sea based nutrition, (naturally iodine containing), may also contribute to the elimination of ID, particularly at times when salt restriction tends to be generally advised. [ABSTRACT FROM AUTHOR]

Abstract

Elderly patients may present with prominent cognitive complaints and have performances in neuropsychological tests within the normal range for the age and education, and thus do not fulfill the criteria for mild cognitive impairment (MCI). There is insufficient evidence to support the clinical decision in these cases ("pre-MCI"). Forty-three subjects, 11 controls, 15 "pre-MCI," and 17 MCI, were followed for about three and half years with neuropsychological testing and magnetic resonance imaging including volumetric measurements of the hippocampus and amygdala. Two of the "pre-MCI" subjects suffered cognitive and functional deterioration and were diagnosed with dementia. Although the "pre-MCI" subjects as a group had no significant deterioration in neuropsychological tests, they suffered a decline in the total hippocampal volume (P=0.04) along the follow-up time. In contrast, all control subjects remained stable and had no volumetric decreases. As expected, MCI patients underwent significant deterioration in several neuropsychological tests, often progressed to Alzheimer's disease, and showed decreases both in total hippocampal and amygdalar volumes. Elderly people presenting with cognitive complaints may be in an initial phase of a degenerative disorder and should be followed clinically, even if they have normal neuropsychological tests.

Abstract

Colour vision impairments have been identified in early stages of neurological disorders such as Parkinson′s disease, and the relative contribution of retinal versus cortical mechanisms remains a matter of intense debate. Similar considerations can be raised concerning other neurological disorders such as Multiple Sclerosis (with or without optic neuritis) and Alzheimer's Disease. This may be due to the fact the retina may mirror the brain in terms of pathology, or suffer from retrograde degeneration in the case of multiple sclerosis. Moreover cortical changes secondary to retinal disease, such as glaucoma and diabetic retinopathy may also bias colour perception. Here we review current evidence concerning the relative role of the retina in colour vision deficits in a broad range of neurological and ophthalmological disorders. In particular, we discuss the potential role of colour vision measures as disease related biomarkers that can be used for diagnostic, prognostic and treatment effects assessment.

Abstract

PURPOSE: To document and analyse the decision to withhold or withdraw life-sustaining treatment (LST) in a population of very old patients admitted to the ICU. METHODS: This prospective study included intensive care patients aged ≥ 80 years in 309 ICUs from 21 European countries with 30-day mortality follow-up. RESULTS: LST limitation was identified in 1356/5021 (27.2%) of patients: 15% had a withholding decision and 12.2% a withdrawal decision (including those with a previous withholding decision). Patients with LST limitation were older, more frail, more severely ill and less frequently electively admitted. Patients with withdrawal of LST were more frequently male and had a longer ICU length of stay. The ICU and 30-day mortality were, respectively, 29.1 and 53.1% in the withholding group and 82.2% and 93.1% in the withdrawal group. LST was less frequently limited in eastern and southern European countries than in northern Europe. The patient-independent factors associated with LST limitation were: acute ICU admission (OR 5.77, 95% CI 4.32-7.7), Clinical Frailty Scale (CFS) score (OR 2.08, 95% CI 1.78-2.42), increased age (each 5 years of increase in age had a OR of 1.22 (95% CI 1.12-1.34) and SOFA score [OR of 1.07 (95% CI 1.05-1.09 per point)]. The frequency of LST limitation was higher in countries with high GDP and was lower in religious countries. CONCLUSIONS: The most important patient variables associated with the instigation of LST limitation were acute admission, frailty, age, admission SOFA score and country.

Abstract

A inflamação, em geral, é uma resposta fisiológica do corpo para com diferentes tipos de lesão do tecido, provocando uma cascata coordenada de reacções celulares e bioquímicas. Distúrbios neurodegenerativos, inflamatórios e neoplásicos envolvem reacções neuroinflamatórias que isolam o tecido danificado e promovem respostas imunitárias. Da mesma forma, a neuroinflamação (NI) implica uma complexa e orquestrada resposta a vários estímulos no sistema nervoso central (SNC), com vista para a preservação do tecido e sua restauração. Reacções neuroinflamatórias envolvem uma resposta celular através da activação de células da linhagem do monócito, residentes ou circulantes. Microglia são as células residentes da linhagem dos monócitos no SNC e a sua activação, constitui uma característica principal da neuroinflamação. O processo envolve uma sobre expressão dos receptores da proteína translocadora de 18 kDa (TSPO) em células da linhagem dos monócitos/macrófagos e, no sistema nervoso central (SNC), pela activação da microglia. PK11195 é um ligando selectivo para o receptor da TSPO e, portanto, um identificador da microglia activada. O enantiómero (R) marcado radioactivamente com carbono-11, (R)-[N-metil-11 C]PK11195, é o radiotraçador mais utilizado para imagiologia in vivo da TSPO com PET. Neste trabalho, reportamos a optimização da síntese, purificação e reformulação de (R)-[N-metil-11 C] PK11195 pelo ‘captive solvente method’ com a finalidade de ser utilizado para imagem in vivo em estudos de PET. Carbono-11 é obtido sob a forma de [ 11 C]CO2 por irradiação de um alvo de gás (N2+O2 0,5%), utilizando a reacção nuclear 14 N(p,α) 11 C num ciclotrão. [ 11 C]CH3I é produzido por redução de [ 11 C]CO2 com LiAlH4/THF (0,1 M) via ‘fase liquida’ a [ 11 C]CH3OLi, e pela adição posterior de HI em um sistema de produção de iodeto de metilo, o [ 11 C]CH3I é destilado a 120ºC. Ao mesmo tempo, o [ 11 C]CH3I destilado é aprisionado num loop previamente carregado com uma solução da molécula precursora desmetilada (R)-[N-desmetil]PK11195 (dissolvida em 100μl de DMSO e saturada com 30mg de KOH), iniciando-se a reacção ao mesmo tempo que se aprisiona o [ 11 C]CH3I. Produtos da reacção ([11C]-X) passam por uma coluna HPLC semipreparativa de fase reversa (C18) para purificação. Finalmente, (R)-[N-metil-11 C]PK11195 foi formulado em 9ml de soro fisiológico (0,9%) e 1ml de EtOH e filtrado através de um filtro esterilizado de membrana de 0,22μm. O processo de síntese realiza-se em cerca de 35 minutos, e testes de controlo de qualidade foram realizados para garantir a boa qualidade do produto. 149,71±50,25mCi de vi (R)-[ 11 C]PK11195 foram obtidos no final da síntese com actividades específicas entre 15-25GBq/μmol num curto período de síntese. O ‘captive solvente loop’ proporciona uma maneira fácil e reprodutível para automatizar a produção de rotina de radiofármacos marcados com 11 C para uso humano. O método de produção é rápida, tendo em conta a curta meia-vida do carbono-11 (20,4 min), podendo-se produzir produtos finais com elevada pureza radioquímica e boa actividade específica.
