This article intends to demonstrate the interconnections between exposure, engagement, human rights (HRs) lens, and methods in social work. To achieve these aims, we used HRXSW, HRESW, HRLSW, and HRMSW index scales to carry out a survey amongst Portuguese social workers. This survey was sent to 4079 registered members (100%) of the Portuguese professional association, of which 259 were valid responses (6.3%). The results of this pilot study show that professionals are exposed to HR in the education system and in the professional practice and that the level of engagement with HR is strong. Professionals revealed that social problems and rights violations played a prominent role during their practices with clients; however, contradictions are noticed in relation with intervention methods. Their methods are mostly informed by individual rights and personal empowerment, collaboration, and accountability and, to a lesser extent, by non-discrimination, micro and meso approach, and activism. We conclude that professionals have the knowledge and courage to consolidate and promote HR; however, in order to advocate for and promote structural social changes that lead to the full realization of an HR utopia, they need to use methods based on structural and collective approaches.

Any successful strategy to prevent and control HCV infection requires an understanding of the epidemic behaviour among the different genotypes. Here, we performed the first characterization of the epidemic history and transmission dynamics of HCV subtypes in Portugal. Direct sequencing of NS5B was performed on 230 direct-acting antiviral drugs (DAA)-treatment naïve patients in Lisbon. Phylogenetic analysis was used for subtyping and transmission cluster identification. Bayesian methods were used to reconstruct the epidemic history of HCV subtypes. Sequences were analysed for resistance-associated substitutions (RAS). The majority of strains were HCV-GT1 (62.6%), GT3 (18.3%, all subtype 3a) and GT4 (16.1%). Among GT1, the most frequent were subtypes 1a (75.5%) and 1b (24.5%). Polyphyletic patterns were found in all but 12 lineages suggesting multiple introductions of the different subtypes in this population. Five distinct epidemics were identified. The first significant HCV epidemic in Portugal occurred between 1930s and 1960s, was caused almost exclusively by GT1b and was likely associated with blood transfusions. Rapid expansion of GT3a occurred in the 1960s and GT1a in the 1980s, associated with intravenous drug use. The most recent epidemics were caused by GT4a and GT4d and seem to be associated with the resurgence of opioid use. The C316N substitution was found in 31.4% of GT1b-patients. Close surveillance of patients bearing this mutation and undergoing dasabuvir-based regimens will be important to determine its impact on treatment outcome.

Microbicides are an important strategy for preventing the sexual transmission of HIV but, so far, the most advanced tenofovir-based microbicides have had modest efficacy. This has been related to adherence problems and high prevalence of tenofovir-resistant HIV-1 strains. P3 is a new peptide with potent activity against HIV that may be a good microbicide candidate. In this work P3 was formulated in a gel of hydroxyethyl cellulose and its activity, stability and safety profile in Balb/c mice were evaluated. HIV infection was fully blocked by a 1.5% gel containing P3 at the IC90 (366.4 nM) concentration. The antiviral activity did not change at 4°C during 4 months and at 25, 37 and 65°C for 1 week. P3 was stable and fully functional at acidic pH up to 24h, under different concentrations of hydrogen peroxide and in the presence of genital fluids up to 48h. P3 had no antibacterial activity and did not affect sperm motility and vitality. Finally, P3 didn't cause significant alterations in the vaginal epithelium of Balb/c mice at 0.06 (456.8 μM) and 0.2 mg/day (1522.7 μM) doses. These findings indicate that P3 is an excellent candidate for further development as a microbicide gel for the prevention of HIV transmission in women.

Objective: To prove the benefits of pelvic floor muscle training with biofeedback (BFB) as a complementary treatment in women with bladder pain syndrome/interstitial cystitis (BPS/IC). Methods: Prospective, randomized study in 123 women with BPS/IC. Groups: BFB+ (n = 48): women with oral drug treatment (perphenazine and amitriptyline) plus intravesical instillations (sodium hyaluronate) plus pelvic floor muscle training with BFB; BFB−: (n = 75): women with oral drug treatment plus intravesical instillations. Variables: age, body mass index (BMI), time of follow-up, length of disease, time free of disease, diseases and health conditions concomitant, and responses to the SF-36 health-related quality of life questionnaire at the first consultation (SF-36 pre-treatment), and at the end of the study (SF-36 post-treatment). The treatment was considered successful when the SF-36 score reached values equal to or greater than 80 points or when the initial value increased by 30 or more points. Results: Mean age was 51.62 years old (23–82). BMI was higher in BFB−. The mean length of BPS/IC condition was 4.92 years (1–20), shorter in BFB+ than in BFB−. Mean SF-36 score pre-treatment was 45.92 points (40–58), lower in BFB+ than in BFB−. Post-treatment SF-36 score was higher than pre-treatment SF-36 score both in BFB+ and BFB−. SF-36 values were higher in BFB+ compared to BFB− over the follow-up. Conclusions: BFB improves quality of life in women with BPS/IC as adjunct therapy to combined oral and intravesical treatment.

Unlike in HIV-1 infection, the majority of HIV-2 patients produce broadly reactive neutralizing antibodies, control viral replication and survive as elite controllers. The identification of the molecular, structural and evolutionary footprints underlying these very distinct immunological and clinical outcomes may lead to the development of new strategies for the prevention and treatment of HIV infection. We performed a side-by-side molecular, evolutionary and structural comparison of the C2, V3 and C3 envelope regions from HIV-1 and HIV-2. These regions contain major antigenic targets and are important for receptor binding. In HIV-2, these regions also have immune modulatory properties. We found that these regions are significantly more variable in HIV-1 than in HIV-2. Within each virus, C3 is the most entropic region followed by either C2 (HIV-2) or V3 (HIV-1). The C3 region is well exposed in the HIV-2 envelope and is under strong diversifying selection suggesting that, like in HIV-1, it may harbour neutralizing epitopes. Notably, however, extreme diversification of C2 and C3 seems to be deleterious for HIV-2 and prevent its transmission. Computer modelling simulations showed that in HIV-2 the V3 loop is much less exposed than C2 and C3 and has a retractile conformation due to a physical interaction with both C2 and C3. The concealed and conserved nature of V3 in the HIV-2 is consistent with its lack of immunodominancy in vivo and with its role in preventing immune activation. In contrast, HIV-1 had an extended and accessible V3 loop that is consistent with its immunodominant and neutralizing nature. We identify significant structural and functional constrains to the diversification and evolution of C2, V3 and C3 in the HIV-2 envelope but not in HIV-1. These studies highlight fundamental differences in the biology and infection of HIV-1 and HIV-2 and in their mode of interaction with the human immune system and may inform new vaccine and therapeutic interventions against these viruses.

CRF14_BG isolates, originally found in Spain, are characterized by CXCR4 tropism and rapid disease progression. This study aimed to identify the origin of CRF14_BG and reconstruct its epidemiological history based on new isolates from Portugal. C2V3C3 env gene sequences were obtained from 62 samples collected in 1993-1998 from Portuguese HIV-1 patients. Full-length genomic sequences were obtained from three patients. Viral subtypes, diversity, divergence rate and positive selection were investigated by phylogenetic analysis. The molecular structure of the genomes was determined by bootscanning. A relaxed molecular clock model was used to date the origin of CRF14_BG. Geno2pheno was used to predict viral tropism. Subtype B was the most prevalent subtype (45 sequences; 73%) followed by CRF14_BG (8; 13%), G (4; 6%), F1 (2; 3%), C (2; 3%) and CRF02_AG (1; 2%). Three CRF14_BG sequences were derived from 1993 samples. Near full-length genomic sequences were strongly related to the CRF14_BG isolates from Spain. Genetic diversity of the Portuguese isolates was significantly higher than the Spanish isolates (0.044 vs 0.014, P<0.0001). The mean date of origin of the CRF14_BG cluster was estimated to be 1992 (range, 1989 and 1996) based on the subtype G genomic region and 1989 (range, 1984-1993) based on the subtype B genomic region. Most CRF14_BG strains (78.9%) were predicted to be CXCR4. Finally, up to five amino acids were under selective pressure in subtype B V3 loop whereas only one was found in the CRF14_BG cluster. CRF14_BG emerged in Portugal in the early 1990 s soon after the beginning of the HIV-1 epidemics, spread to Spain in late 1990 s as a consequence of IVDUs migration and then to the rest of Europe. CXCR4 tropism is a general characteristic of this CRF that may have been selected for by escape from neutralizing antibody response.

Objectives: to demonstrate the benefits of physiotherapy (PT) with pelvic floor biofeedback (BFB) in improving health-related quality of life when used as a complementary therapy after surgical treatment of cystocele, in cases in which perineal pain or discomfort persists. Materials and methods: prospective observational study in 226 women who received complementary therapy after surgical treatment of cystocele due to persistent perineal discomfort or pain. Groups: GA (n = 78): women treated with 25 mg of oral pregabalin every 12 h plus BFB, consisting of 20 once-weekly therapy sessions, each 20 min long, with perineal pregelled surface electrodes connected to a screen which provides visual feedback; GB (n = 148): women treated with oral pregabalin 25 mg every 12 h without BFB. Variables: age, body mass index (BMI), time since onset of cystocele prior to surgery (TO), SF-36 health-related quality of life survey score, diseases and concomitant health conditions, follow-up time, success, or failure of postsurgical treatment. Results: average age 67.88 years (SD 12.33, 30–88), with no difference between GA and GB. Average body mass index (BMI) 27.08 (SD 0.45, 18.74–46.22), with no difference between GA and GB. Time since onset of cystocele prior to surgery (TO) was 6.61 years (SD 0.6), with no difference between GA and GB. Pretreatment SF-36 score was lower in GA success than GB success. Treatment was successful in 141 (63.20%) women and failed in 82 (36.80%). PT and age were the main predictors of success, and the least important were pretreatment SF-36 and the time elapsed after the intervention. In GA, 63 women (80.80%) showed improvement while 15 (19.20%) did not. Age was the main predictor of treatment success, while the least important was BMI. In GB, 78 women (53.80%) showed improvement while 67 (46.20%) did not improve. The main predictor was time since cystocele onset prior to surgery, while the least important was age. The odds ratio (OR) of improving quality of life for each unit increase in SF-36 was 11.5% (OR = 0.115) in all patients, with no difference between success and failure; in GA it was 23.80% (OR = 0.238), with a difference between success and failure; in GB it was 11.11% (OR = 0.111), with no difference between success and failure. GA and GB success had more history of eutocic delivery. GA success had more rUTI. GB success and GA failure both had more history of UI corrective surgery. The “failure” outcome had a higher number of patients with more than two concomitant pathological conditions. Conclusions: BFB as an adjunctive treatment improves quality of life in women suffering from persistent discomfort after surgery for cystocele. Young women who meet the criteria for recurrent urinary tract infection or who have a history of eutocic delivery show greater improvement. Body mass index does not influence response to treatment, while the presence of more than two concomitant conditions indicates a poor prognosis for improving quality of life.

Development of new immunogens eliciting broadly neutralizing antibodies (bNAbs) is a main priority for the HIV-1 vaccine field. Envelope glycoproteins from non-B-non-C HIV-1clades have not been fully explored as components of a vaccine. We produced Vaccinia viruses expressing a truncated version of gp120 (gp120t) from HIV-1 clades CRF02_AG, H, J, B, and C and examined their immunogenicity in mice and rabbits. Mice primed with the recombinant Vaccinia viruses and boosted with the homologous gp120t or C2V3C3 polypeptides developed antibodies that bind potently to homologous and heterologous envelope glycoproteins. Notably, a subset of mice immunized with the CRF02_AG-based envelope immunogens developed a cross-reactive neutralizing response against tier 2 HIV-1 Env-pseudoviruses and primary isolates. Rabbits vaccinated with the CRF02_AG-based envelope immunogens also generated potent binding antibodies, and one animal elicited antibodies that neutralized almost all (13 of 16, 81.3%) tier 2 HIV-1 isolates tested. Overall, the results suggest that the novel CRF02_AG-based envelope immunogens and prime-boost immunization strategy elicit the type of immune responses required for a preventive HIV-1 vaccine.

El objetivo del presente articulo es estudiar el proceso de fundación de la nueva Casa de Moneda en Guatemala, erigida a petición de las autoridades del reino para paliar la carestía de numerario circulante y para acuñar in situ los metales obtenidos en el àrea. Para su realización se han investigado la bibliografía y las fuentes disponibles, principalmente las que se encuentran en el Archivo General de Indias, así como el estudio directo de las propias monedas que han llegado hasta la actualidad. En este trabajo se destacan los principales hitos de dicho proceso y las principales características de las monedas emitidas, las cuales, según especialistas no proporcionaron suficiente numerario para monetizar la economía, aunque circularon incluso después de la independencia de los países centroamericanos. The aim of this paper is to study the process of the foundation of a new Mint in Guatemala, erected at the request of the authorities of the kingdom to alleviate the shortage of circulating and the coining of the metals obtained in the area. For its realization it has been studied the bibliography and available sources, especially those found in the General Archive of the Indies, and the direct study of the coins that have survived to the date. This study highlights the main milestones of this process, and the main characteristics of the coins issued, which according to some authors didn't provided enough money to monetize the economy, which continued in circulation even after the independence of the Central American countries.
