Abstract
Introduction
Covid-19 does not only have repercussions on the physical level, representing a new way of life, both individually and in society. The pandemic results in invisible consequences for the population’s mental health.
Objectives
This study aimed to explore the consequences of Covid-19 on mental health in Portugal with a view to understanding and promoting the well-being and happiness of the Portuguese.
Methods
The study included 111 young people and adults, aged between 18 and 58 years (M= 21.81, SD= 5.34), with 43.7% males and 52.7% females. A sociodemographic questionnaire was applied to all participants, as well as the Échelle de Mesure des Manifestations du Bien-Être Psychologique (ÈMMBEP; Massé et al., 1998 - Portuguese translation by Monteiro, Tavares & Pereira, 2012) which translates into a response scale 5-point Likert type, with five subscales, including happiness. In addition, a semistructured interview with data collection instruments was administered.
Results
The results obtained demonstrate the negative impact of Covid-19 on the level of well-being, regardless of the participant’s gender or age.
Conclusions
The data presented point to the need to sensitize individuals to the risk of the pandemic in terms of mental health, thus increasing society’s awareness of the psychological effects of this new global disease. Therefore, coping mechanisms are essential to promote well-being and successfully overcome the pandemic.

Abstract
Advanced maternal age is associated not only with a significant reduction in fertility but also with an additional risk of developing pregnancy-related disorders. Most of these disorders are now believed to be the clinical manifestation of an incorrect placentation, namely deficient transformation of maternal spiral arteries and ineffective trophoblast invasion through uterine stroma. In the present study it was hypothesized that an age-related loss in uterine redox homeostasis interferes with the function of extravillous trophoblasts (EVTs) and placentation. To test this hypothesis, relative levels of oxidatively modified proteins were evaluated in human samples from placenta and placental bed, and the role of specific oxidative modifications to proteins in placentation was studied using a cell culture model of EVTs. In the placental bed, the carbonylation level of a 66 kDa protein (identified as albumin) presented a strong, positive and significant correlation with maternal age. Albumin was immunodetected preferentially in endothelial cells and connective tissue between muscle fascicles. In vitro results showed that carbonylated albumin overload did not alter cell viability, but reduced EVTs motility and triggered cell stress response pathways. Moreover, EVTs presented decreased ability to adhere to and invade a collagen extracellular matrix pre-treated with carbonylated albumin. In conclusion, reproductive ageing is accompanied by an increase in maternal uterine carbonylated albumin, that may have a deleterious role in the modulation of EVTs function.

Abstract
There are several described anatomical variants of the cervical spine, ranging from common to extremely rare, which may have different clinical implications. We present the case of an extremely rare anatomical variant of the cervical spine, in a symptomatic patient, consisting of a unilateral accessory articulation between the 5th and 6th cervical vertebrae, due to elongated anterior transverse processes. Our search found only three cases in the English literature describing similar findings to the case here reported. Our case is, to our knowledge, the first report of this anatomical variant imaged with computed tomography including post-processing images (volume rendering technology and multiplanar reformations), which contribute greatly to a better understanding and depiction of the anatomical variant.

Abstract
Blood flow assessment employing Doppler techniques is a useful procedure in pregnancy evaluation, as it may predict pregnancy disorders coursing with increased uterine vascular impedance, as pre-eclampsia. While the local causes are unknown, emphasis has been put on reactive oxygen species (ROS) excessive production. As NADPH oxidase (NOX) is a ROS generator, it is hypothesized that combining Doppler assessment with NOX activity might provide useful knowledge on placental bed disorders underlying mechanisms. A prospective longitudinal study was performed in 19 normal course, singleton pregnancies. Fetal aortic isthmus (AoI) and maternal uterine arteries (UtA) pulsatility index (PI) were recorded at two time points: 20-22 and 40-41 weeks, just before elective Cesarean section. In addition, placenta and placental bed biopsies were performed immediately after fetal extraction. NOX activity was evaluated using a dihydroethidium-based fluorescence method and associations to PI values were studied with Spearman correlations. A clustering of pregnancies coursing with higher and lower PI values was shown, which correlated strongly with placental bed NOX activity, but less consistently with placental tissue. The study provides evidence favoring that placental bed NOX activity parallels UtA PI enhancement and suggests that an excess in oxidation underlies the development of pregnancy disorders coursing with enhanced UtA impedance.

Abstract
The objective of this work was to compare Doppler flows pulsatility index (PI) and resistance indexes (RI) of uterine and internal iliac arteries during pregnancy in low risk women and in those with stage-1 essential hypertension. From January 2010 and December 2012, a longitudinal and prospective study was carried out in 103 singleton uneventful pregnancies (72 low-risk pregnancies and 31 with stage 1 essential hypertension)at the 1st, 2nd and 3rd trimesters. Multiple linear regression models, fitted using generalized least squares and whose errors were allowed to be correlated and/or have unequal variances, were employed; a model for the relative differences of both arteries impedance was utilized. In both groups, uterine artery PI and RI exhibited a gestational age related decreasing trend whereas internal iliac artery PI and RI increased. The model testing the hemodynamic adaptation in women with and without hypertension showed similar trend. Irrespective of blood pressure conditions, the internal iliac artery resistance pattern contrasts with the capacitance pattern of its immediate pelvic division, suggesting a pregnancy-related regulatory mechanism in the pelvic circulation.

Abstract
Audio computer-assisted survey instrument (ACASI) has been shown to decrease under-reporting of socially undesirable behaviours, but has not been evaluated in pregnant women at risk of HIV acquisition in Brazil. We assigned HIV-negative pregnant women receiving routine antenatal care at in Porto Alegre, Brazil and their partners to receive a survey regarding high-risk sexual behaviours and drug use via ACASI (n = 372) or face-to-face (FTF) (n = 283) interviews. Logistic regression showed that compared with FTF, pregnant women interviewed via ACASI were significantly more likely to self-report themselves as single (14% versus 6%), having >5 sexual partners (35% versus 29%), having oral sex (42% versus 35%), using intravenous drugs (5% versus 0), smoking cigarettes (23% versus 16%), drinking alcohol (13% versus 8%) and using condoms during pregnancy (32% versus 17%). Therefore, ACASI may be a useful method in assessing risk behaviours in pregnant women, especially in relation to drug and alcohol use.

Abstract
SLC26A2-related dysplasias encompass a spectrum of diseases: from lethal achondrogenesis type 1B (ACG1B; MIM #600972) and atelosteogenesis type 2 (AO2; MIM #256050) to classical diastrophic dysplasia (cDTD; MIM #222600) and recessive multiple epiphyseal dysplasia (rMED; MIM #226900). This study aimed at characterizing clinically, radiologically and molecularly 14 patients affected by non-lethal SLC26A2-related dysplasias and at evaluating genotype-phenotype correlation. Phenotypically, eight patients were classified as cDTD, four patients as rMED and two patients had an intermediate phenotype (mild DTD - mDTD, previously 'DTD variant'). The Arg279Trp mutation was present in all patients, either in homozygosity (resulting in rMED) or in compound heterozygosity with the known severe alleles Arg178Ter or Asn425Asp (resulting in DTD) or with the mutation c.727-1G>C (causing mDTD). The 'Finnish mutation', c.-26+2T>C, and the p.Cys653Ser, both frequent mutations in non-Portuguese populations, were not identified in any of the patients of our cohort and are probably very rare in the Portuguese population. A targeted mutation analysis for p.Arg279Trp and p.Arg178Ter in the Portuguese population allows the identification of approximately 90% of the pathogenic alleles.

Abstract
Effects of ET(B) receptor stimulation and its subcellular pathways were evaluated in carbachol pre-contracted rabbit iris sphincter muscles (n=51). ET(B) stimulation with sarafotoxin (SRTX-c; 10(-10)-10(-6) M) was tested in the absence (n=7) or presence of 10(-5) M of: BQ-788 (ET(B2) receptor antagonist; n=6), L-NA (NOS inhibitor; n=7) or indomethacin (cyclooxygenase inhibitor; n=10). Effects of ET(B) stimulation by endothelin-1 (ET-1; 10(-10)-10(-7) M) in the presence of an ET(A) receptor antagonist (BQ-123; 10(-5) M; n=7) and of ET(B1) stimulation by IRL-1620 (10(-10)-10(-7) M; n=7) were also tested. Finally, the effects of SRTX-c (10(-9)-10(-7) M) in electric field stimulation (EFS) contraction were evaluated (n=7). ET(B) receptor stimulation by SRTX-c or ET-1 in presence of BQ-123 promoted a concentration-dependent relaxation of the rabbit iris sphincter muscle by 10.8+/-2.0% and 9.4+/-1.8%, respectively. This effect was blocked by BQ-788 (-2.3+/-2.0 %), L-NA (4.5+/-2.3 %) or indomethacin (2.3+/-2.9 %). Selective ET(B1) stimulation by IRL-1620 did not relax the iris sphincter muscle (0.9+/-5.4 %). EFS elicited contraction was not altered by SRTX-c. In conclusion, ET(B) receptor stimulation relaxes the carbachol precontracted iris sphincter muscle, an effect that is mediated by the ET(B2) receptor subtype, through NO and the release of prostaglandins.

Abstract
Neocentromeres are functional centromeres located in non-centromeric euchromatic regions of chromosomes. The formation of neocentromeres results in conferring mitotic stability to chromosome fragments that do not contain centromeric alpha satellite DNA. We present a report of a prenatal diagnosis referred to cytogenetic studies due to ultrasound malformations such as large cisterna magna, no renal differentiation, hypotelorism and ventriculomegaly. Cytogenetic analysis of GTG-banded chromosomes from amniotic fluid cells and fetal blood cells revealed a de novo small supernumerary marker chromosome. Molecular cytogenetic studies using fluorescence in situ hybridization and comparative genomic hybridization showed this marker to be an inverted duplication of the distal portion of chromosome 13q which did not contain detectable alpha satellite DNA. The neocentromeric constriction was located at band 13q31. The presence of a functional neocentromere on this marker chromosome was confirmed by immunofluorescence with antibodies to centromere protein-C. The anatomopathologic study revealed a female fetus with facial dysmorphisms, low set ears and renal dysplasia. Ten small supernumerary neocentromeric chromosomes originating from the distal region of chromosome 13q have been reported to date. There are only three additional cases described with the location of the neocentromere in band 13q31. This is the first reported case detected prenatally.

Abstract
The trypanocidal activity of racemic mixtures of cis- and trans-methylpluviatolides was evaluated in vitro against trypomastigote forms of two strains of Trypanosoma cruzi, and in the enzymatic assay of T. cruzi gGAPDH. The cytotoxicity of the compounds was assessed by the MTT method using LLC-MK2 cells. The effect of the compounds on peroxide and NO production were also investigated. The mixture of the trans stereoisomers displayed trypanocidal activity (IC50 approximately 89.3 microM). Therefore, it was separated by chiral HPLC, furnishing the (+) and (-)-enantiomers. Only the (-)-enantiomer was active against the parasite (IC50 approximately 18.7 microM). Despite being inactive, the (+)-enantiomer acted as an antagonistic competitor. Trans-methylpluviatolide displayed low toxicity for LLC-MK2 cells, with an IC50 of 6.53 mM. Furthermore, methylpluviatolide neither inhibited gGAPDH activity nor hindered peroxide and NO production at the evaluated concentrations.

Abstract
Axenfeld-Rieger syndrome (ARS) is a genetically heterogeneous autosomal dominant disorder mainly characterized by developmental defects of the anterior segment and extraocular anomalies. ARS shows great clinical variability and encompasses several conditions with overlapping phenotypes, including Rieger syndrome (RS). RS is characterized by developmental defects of the eyes, teeth and umbilicus, and the main causative gene is PITX2 (paired-like homeodomain transcription factor 2, or RIEG1) at 4q25. PITX2 mutations show great variety, from point mutations to microscopic or submicroscopic deletions, and apparently balanced translocations in few cases. We identified cytogenetically undetectable submicroscopic deletions at 4q25 in two unrelated patients diagnosed with RS. One patient had a t(4;17)(q25;q22)dn translocation with a deletion at the 4q breakpoint, and the other patient had an interstitial deletion of 4q25. Both deletions included only the PITX2 and ENPEP (glutamyl aminopeptidase) genes.

Abstract
Ghrelin is a recently described acylated peptide, which works as a somatosecretagogue and has described effects on the smooth, skeletal and cardiac muscle. We examined the production and effects of ghrelin on relaxation of the iris muscles. Contractile effects of 1-5 human ghrelin (frGhr, 10(-9)-6 x 10(-5)M) and 1-5 human des-octanoyl-ghrelin (d-frGhr; 10(-9)-6 x 10(-5)M) were tested on iris rabbit sphincter (n=11 frGhr; n=7 d-frGhr), dilator (n=6 frGhr; n=6 d-frGhr) and rat sphincter (n=6 frGhr; n=8 d-frGhr) precontracted muscles. On rabbit sphincter the effect of frGhr was also tested in presence of: i) L-NA (10(-5)M; n=7); ii) indomethacin (10(-5)M; n=7); iii) DLys(3)GHRP6 (10(-4)M; n=6); and iv) apamin+carybdotoxin (10(-6)M; n=6). Furthermore, on rabbit dilator the effect of frGhr was tested in presence of DLys(3)GHRP6 (10(-4)M; n=7). Finally, ghrelin mRNA production was assessed by "in situ" hybridization in Wistar rat eyes (n=8). In all muscles, frGhr promoted a concentration-dependent relaxation, maximal at 6 x 10(-5)M, 1.5-3 min after its addition, decreasing tension by 34.1+/-12.1%, 25.8+/-4.8% and 52.1+/-10.3% in the rabbit sphincter, dilator and rat sphincter, respectively. In the rabbit sphincter the relaxing effects of frGhr were: (i) enhanced in presence of DLys(3)GHRP6 (118.1+/-21.1%); (ii) blunted by indomethacin; and (iii) not altered by apamin+carybdotoxin (36.4+/-14.4%) or L-NA (52.4+/-11.4%). Relaxing effects of d-frGhr in rabbit (43.3+/-5.2%) and rat (77.1+/-15.3%) sphincter muscles were similar to those of frGhr. In rabbit dilator muscle, d-frGhr did not significantly alter active tension and the relaxing effect of frGhr was blunted by GHSR-1a blockage. Ghrelin mRNA was identified in iris posterior epithelium. In conclusion, ghrelin is a novel, locally produced, relaxing agent of iris dilator and sphincter muscles, an effect that is mediated by GHSR-1a in the former, but not in the latter. Furthermore, in the sphincter it seems to be mediated by prostaglandins, but not by NO or K(Ca) channels.

Abstract
Trypanosoma cruzi, the agent of Chagas disease, is known to cause enhanced nitric oxide (NO) production, which might be involved in host resistance. The inducible nitric-oxide-synthase (iNOS) is assumed to be responsible for the NO increase after several infections. We studied the potential role of NO in Calomys callosus, a natural reservoir of this protozoan parasite. The concentration of NO was determined in spleen and liver of animals infected with two different T. cruzi strains, BOL and BOL-SB. Furthermore, the iNOS mRNA expression was quantified in the same cell types. NO production was detectable in both tissues exhibiting only slight differences compared to non-infected controls. All measured NO values were significantly lower than those reported for a number of different mouse strains, which displayed extremely enhanced NO levels after T. cruzi infection. Surprisingly, iNOS mRNA expression was induced in infected C. callosus but without subsequent increase of NO levels, indicating a post-transcriptional regulation mechanism. In summary, our results, indicate that the tolerance of C. callosus to T. cruzi is only accompanied by non-toxic NO intracellular concentrations.

Abstract
The intracellular parasite Trypanosoma cruzi, the causative agent of Chagas disease, is known to comprise heterogeneous populations. One possibility to explain the obviously distinct phenotypes of different T. cruzi strains is differential expression of particular genes. This could result in environmental adaptations of the parasite within host organs, leading to distinct clinical symptoms. With the aim of identifying differentially expressed genes, we examined different T. cruzi strains by suppression subtractive hybridization analysis. The isolated clones were sequenced and Blasted for sequence-homology with known T. cruzi genes. A stage-specific glycoprotein (82gp), an 85-kDa protein with homology to heat-shock proteins, a beta-tubulin gene, a hexosetransporter, a dehydrogenase/ prostaglandin F2alpha-synthase and a cathepsin B-like protease were identified. The expression of these genes was analyzed by RT-PCR. Diverse expression patterns were detected for different T. cruzi strains, but no specific correlation between the gene expression and the classification of groups could be found. We discuss the presumed importance of these T. cruzi gene expression patterns for future strategies of molecular therapy of Chagas disease. For pathological studies, other parameters such as distinct gene/antigen expression could also be of interest, because they probably likewise correlate with distinct phenotypes.

Abstract
OBJECTIVE The purpose of this study was to characterise the occurrence of multiple primitive gynaecological malignant neoplasias, restricted to the genital tract and breast or associated with other organs, and to detect which types of association are most frequent concerning location, histology and staging. POPULATION AND METHODS The records of patients with gynaecological cancer at the Portuguese Institute of Oncology--Lisbon Centre, between 1986 and 1993 were used in this study. RESULTS Of the 10,746 women with gynaecological cancer, 91 (0.8%) were found to have a second primitive malignant neoplasia. Of these neoplasias, 64% (58 cases) were also located at a gynaecological site. The most frequent associations were endometrium/breast (13 cases), bilateral breast (12 cases) and ovary/endometrium (11 cases). The majority of primitive multiple gynaecological tumours were synchronous. Regarding gynaecological cancer and non-gynaecological cancer, in 28 cases (31%), the most common non-gynaecological location was the colon/rectum. Five patients had triple tumours. CONCLUSION Although these situations are relatively rare the possibility of multiple primitive cancers should be considered with the presence of malignant tumours in two or more organs. This distinction between multiple primitive or metastatic cancers could be important for treatment as well as prognosis.

Abstract
A patient with synchronous multiple malignant neoplasms of the female genital tract, involving the ovary, the cervix and the endometrium is described. A 49-year-old patient, presenting pelvic pain and menometrorrhagia over the last six months. An abdominal and speculum examination revealed an abnormal mass occupying the entire left lower quadrant and a vegetating tumor of the cervix, respectively. Microscopic examination of the uterus and ovary revealed a cystadenocarcinoma of the ovary and an adenosquamous carcinoma of the cervix and an endometrioid carcinoma of the endometrium. The data suggests this is a multiple mullerian tumor. Due to treatment and prognostic implications, in the presence of a patient with a tumor involving different organs, we must not overlook differential diagnosis between primary and metastatic tumor.

Abstract
OBJECTIVE To analyse the attitude, physical and psychological repercussions of sterilisation on Portuguese women in order to determine their quality of life. PROJECT Retrospective study of women submitted to sterilisation between 1988 and 1991, by means of a questionnaire mailed in June 1992. LOCATION Family planning clinic, S. Francisco Xavier Hospital, Lisbon. POPULATION Between 1988 and 1991, 540 women were sterilised at the Gynaecology/Obstetrics Department of S. Francisco Xavier, 308 of which were included in the study (women who were sterilised with a pathology which might interfere with the results and those who were sterilised during a caesarean section, post partum or post abortion were excluded). MAIN DETERMINATIONS: Descriptive and demographic data taken from the clinical files and the results of a mailed questionnaire with eleven groups of questions on their attitudes, opinions and behaviour as well as gynaecological and sexual complaints, all with regard to sterilisation. RESULTS 106 women (34.5%) replied to the mailed questionnaire. An overwhelming majority felt satisfied (97.1%) and well informed (98%) regarding sterilisation. Sexual satisfaction and coital frequency improved or remained the same in 92.1% of the women and a slightly lower number (85.3%) stated that their sexual interest had improved or remained the same. All the women stated that the sexual interest of their partners had not diminished. The symptoms which were most frequently referred to as being worse or which had recurred were alterations in the menstrual cycle (43.1%), dysmenorrhea (16.7%) and mastodynia (16.7%). CONCLUSION The majority of women (3/4) presented good or very good results in terms of quality of life.

Abstract
The effect of an intravenous maternal glucose load upon fetal activity and FHR was studied 51 times in 48 pregnancies at 34 or more weeks, in which the fetuses were classified as non-reactive during the NST. The initiation of fetal muscular activity was observed in 44 instances (41 fetuses) approximately 6 minutes after a 6 grams glucose load to the mother, which lead to the diagnosis of a state of fetal well-being without the need of a CST. In the 7 cases which were not responsive to the load, CSTs were performed; of these, 5 were positive, 1 negative and 1 suspicious. These pregnancies resulted in one fetal death during the 12 hours following CST and 5 newborns showed an APGAR Score less than 4 at one minute, with 2 neo-natal deaths. The reason for the negative glucose load test with negative CST was probably related to hemodynamic changes induced by intra-amniotic bleeding following a bloody amniocentesis, and not to the lack of fetal energy substate. The proposed method may constitute a screening possibility for the clinical management and prognosis of the hypoactive fetus, because the glucose load to the mother may release the somatic activity of the non-hypoxemic fetus. A fetus unable to show any significant increase in glucose uptake, even with increasing maternal-fetal gradients, could be identified by the negative response to the test.
