RESUMO
The onset of the Coronavirus disease (COVID-19) pandemic forced higher education institutions to abruptly transition to remote services and online learning. Students with a foster care background are a subgroup of students who have been particularly hard hit by the pandemic, as were the campus-based programs (CSPs) designed to support them. The purpose of this study was to learn about the impact of the pandemic on CSPs and CSP participants. Focus groups were conducted with CSP administrators and separately with CSP students from two- and four-year colleges in California. The first theme that emerged from the data focused on challenges exacerbated by the pandemic, with six subthemes zeroing in on breaks in social connections, academic disruptions, technology woes, gaps in basic needs, employment challenges, and the toll on mental health. The second theme described participants' responses, including their creative and collaborative actions. Administrators quickly adapted service delivery, formed partnerships with new units and organizations to ensure students' needs were met, and found creative ways to stay connected with students during a time of pervasive isolation. Students talked about their own efforts to access resources, connect with peers, and use of strategies to manage challenges such as burnout and depression. A second subtheme highlighted the ways participants displayed resilience, such as creating boundaries to manage their own self-care and leaning on each other for support. The findings from this study increase our understanding of the experiences students faced during the pandemic and shed light on implications moving forward to support students with foster care histories in higher education.
RESUMO
The analytical performance of the new Alere™ i Influenza A&B kit (AL-Flu) assay, based on isothermal nucleic acids amplification, was evaluated and compared with an antigen detection method, SD Bioline Influenza Virus Antigen Test (SDB), and an automated real-time RT-PCR, Simplexa™ Flu A/B & VRS Direct assay (SPX), for detection of influenza viruses. An "in-house" RT-PCR was used as the reference method. Sensitivity of AL-Flu, SDB, and SPX was 71.7%, 34.8%, and 100%, respectively. Specificity was 100% for all techniques. The turnaround time was 13min for AL-Flu, 15min for SDB, and 75min for SPX. The Alere™ i Influenza A&B assay is an optimal point-of-care assay for influenza diagnosis in clinical emergency settings, and is more sensitive and specific than antigen detection methods.

UNLABELLED: Human parechoviruses (HPeV) have been recently recognized as important viral agents in paediatric infections. The aims of this study were to investigate the HPeV infection prevalence in infants <1 month in Spain and, secondly, to analyse the clinical and epidemiological characteristics of the infected patients compared with those infected by enterovirus (EV). Infants <1 month with neurological or systemic symptoms were included in a multicentre prospective study. EV and HPeV detection by RT-PCR and genotyping were performed in cerebrospinal fluids (CSF), sera or throat swabs. Out of the total of 84 infants studied during 2013, 32 were EV positive (38 %) and 9 HPeV positive (11 %). HPeV-3 was identified in eight cases and HPeV-5 in one. Mean age of HPeV-positive patients was 18 days. Diagnoses were fever without source (FWS) (67 %), clinical sepsis (22 %) and encephalitis (11 %). Leukocytes in blood and CSF were normal. Pleocytosis (p = 0.03) and meningitis (p = 0.001) were significantly more frequent in patients with EV infections than with HPeV. CONCLUSIONS: Although HPeV-3 infections were detected less frequently than EV, they still account for approximately 10 % of the cases analysed in infants younger than 1 month. HPeV-3 was mainly associated with FWS and without leukocytosis and pleocytosis in CSF. In these cases, HPeV screening is desirable to identify the aetiologic agent and prevent unnecessary treatment and prolonged hospitalization.

INTRODUCTION: The incidence of tuberculosis (TB) among the native population in Spain continues to decrease, resulting in a higher proportion of foreign-born cases. The aim of this study was to identify the differential TB characteristics within the immigrant population with respect to the native population in the South Granada Health Area, Spain. METHODS: This was a descriptive study, including all cases of TB diagnosed during the period 2003-2010. Cases were identified through a prospective database. A logistic regression analysis was performed to determine differential characteristics. RESULTS: From 319 TB cases diagnosed, 247 were natives and 72 (22.6%) immigrants, and 272 were pulmonary tuberculosis. The following variables were significantly associated with immigrant TB cases: age<35 years (OR=4.75, CI: 2.72-8.31), higher percentage of cavitated chest X-ray (OR=2.26, CI: 1.20-4.20), higher percentage of smear-positive cases (OR=1.80, CI: 1.02-3.16), longer diagnostic delay in smear-positive pulmonary TB (median 32 days vs. 21 days P=.043), and lower total lethality (OR=0.12; CI: 0.01-0.89). CONCLUSIONS: The incidence of TB has remained constant in the South Granada Health Area due to the increase in cases among immigrants. Compared with native TB patients, immigrant patients were younger and had more advanced disease (higher percentage of smear-positive cases and higher percentage of cavitated chest X-ray) and longer diagnostic delay in smear-positive pulmonary TB, indicating poorer TB control. Strategies for earlier diagnosis of TB in immigrants are essential.

Prevalence of human cytomegalovirus infection is very high worldwide. Following primary infection, the virus remains latent, being able to cause recurrences either by reinfection with a new strain or by reactivation of the replication of the latent virus. The most severe disease is seen in congenital infection and in immunosuppressed patients, in whom the virus act as an opportunistic pathogen. Serological techniques are the methods of choice in primary infection and to determine the immune status against CMV in organ donor and receptor. Although well-standardized studies are lacking, the recent commercial availability of methods that measure cellular immune response are promising to predict the risk of CMV disease in immunosuppressed individuals. Molecular assays, that have gradually been substituting viral culture and/or antigen detection, are the most widely used methods for the diagnosis and control of CMV infection.

Prader-Willi syndrome (PWS) is a genetic disorder produced by a lack of expression of paternally derived genes in the 15q11-13 region. Research has generally focused on its genetic and behavioral expression, but only a few studies have examined epigenetic influences. Prenatal testosterone or the maternal testosterone-to-estradiol ratio (MaTtEr) has been suggested to play an important role in the development of the 'social brain' during pregnancy. Some studies propose the 2D:4D digit ratio of the hand as an indirect MaTtEr measure. The relationship between social performance and MaTtEr has been studied in other neurodevelopmental conditions such as Autism Spectrum Disorder (ASD), but to our best knowledge, it has never been studied in PWS. Therefore, our study aims to clarify the possible existence of a relationship between social performance-as measured using the Social Responsiveness Scale (SRS)-and MaTtEr levels using the 2D:4D ratio. We found that, as a group, PWS individuals have shorter index and ring fingers than the control group, but no significant difference in the 2D:4D ratios. The 2D:4D ratio showed a correlation only with Restricted Interests and Repetitive Behavior Subscale, where a positive correlation only for male individuals with PWS was found. Considering only PWS with previous GH treatment during childhood/adolescence (PWS-GH), index and ring fingers did not show differences in length with the control group, but the 2D:4D ratio was significantly higher in the right or dominant hand compared to controls.
RESUMO
The 2020-21 West Nile Virus (WNV) outbreak in Andalusia, Spain, was the largest reported in the country, with eight cases of West Nile Neuroinvasive Disease (WNND) diagnosed in a tertiary hospital. Diagnosis of WNND is based on detecting WNV RNA, viral isolation, or demonstrating a specific immune response against the virus, with additional tests used to support the diagnosis. Treatment remains supportive, with variable outcomes. The potential efficacy of plasma exchange (PLEX) in select cases raises the possibility of an autoimmune component secondary to infectious pathology of the central nervous system. The influence of climate change on the expansion of WNV into new regions is a significant concern. It is crucial for physicians practicing in high-risk areas to be knowledgeable about the disease for early prevention and effective control measures.

West Nile virus (WNV) is an arbovirus usually transmitted by mosquitoes. The main reservoirs are birds, although the virus may infect several vertebrate species, such as horses and humans. Up to 80% of human infections are asymptomatic. The most frequent clinical presentation is febrile illness, and neuroinvasive disease can occur in less than 1% of cases. Spain is considered a high-risk area for the emergence of WNV due to its climate and the passage of migratory birds from Africa (where the virus is endemic). These birds nest surrounding wetlands where populations of possible vectors for the virus are abundant. Diagnosis of human neurological infections can be made by detection of IgM in serum and/or cerebrospinal fluid samples, demonstration of a four-fold increase in IgG antibodies between acute-phase and convalescent-phase serum samples, or by detection of viral genome by reverse transcription-polymerase chain reaction (especially useful in transplant recipients). Since WNV is a biosafety level 3 agent, techniques that involve cell culture are restricted to laboratories with this level of biosafety, such as reference laboratories. The National Program for the Surveillance of WNV Encephalitis allows the detection of virus circulation among birds and vectors in areas especially favorable for the virus, such as wetlands, and provides information for evaluation of the risk of disease in horses and humans.

The sandfly fever Toscana virus (TOSV, genus Phlebovirus, family Phenuiviridae) is endemic in Mediterranean countries. In Spain, phylogenetic studies of TOSV strains demonstrated that a genotype, different from the Italian, was circulating. This update reports 107 cases of TOSV neurological infection detected in Andalusia from 1988 to 2020, by viral culture, serology and/or RT-PCR. Most cases were located in Granada province, a hyperendemic region. TOSV neurological infection may be underdiagnosed since few laboratories include this virus in their portfolio. This work presents a reliable automated method, validated for the detection of the main viruses involved in acute meningitis and encephalitis, including the arboviruses TOSV and West Nile virus. This assay solves the need for multiple molecular platforms for different viruses and thus, improves the time to results for these syndromes, which require a rapid and efficient diagnostic approach.

Toscana virus (TOSV) can cause central nervous system infections in both residents of and travelers to Mediterranean countries. Data mining identified three real-time RT-qPCR assays for detecting TOSV RNA targeting non-overlapping regions in the nucleoprotein gene. Here, they were combined to create a multi-region assay named Trio TOSV RT-qPCR consisting of six primers and three probes. In this study, (i) we evaluated in silico the three RT-qPCR assays available in the literature for TOSV detection, (ii) we combined the three systems to create the Trio TOSV RT-qPCR, (iii) we assessed the specificity and sensitivity of the three monoplex assays versus the Trio TOSV RT-qPCR assay, and (iv) we compared the performance of the Trio TOSV RT-qPCR assay with one of the reference monoplex assays on clinical samples. In conclusion, the Trio TOSV RT-qPCR assay performs equally or better than the three monoplex assays; therefore, it provides a robust assay that can be used for both research and diagnostic purposes.
RESUMO
During recent decades West Nile Virus (WNV) outbreaks have continuously occurred in the Mediterranean area. In August 2020 a new WNV outbreak affected 71 people with meningoencephalitis in Andalusia and six more cases were detected in Extremadura (south-west of Spain), causing a total of eight deaths. The whole genomes of four viruses were obtained and phylogenetically analyzed in the context of recent outbreaks. The Andalusian viral samples belonged to lineage 1 and were relatively similar to those of previous outbreaks which occurred in the Mediterranean region. Here we present a detailed analysis of the outbreak, including an extensive phylogenetic study. As part on this effort, we implemented a local Nextstrain server, which has become a constituent piece of regional epidemiological surveillance, wherein forthcoming genomes of environmental samples or, eventually, future outbreaks, will be included.

A new oligochromatographic assay, Speed-Oligo Novel Influenza A H1N1, was designed and optimized for the specific detection of the 2009 influenza A H1N1 virus. The assay is based on a PCR method coupled to detection of PCR products by means of a dipstick device. The target sequence is a 103-bp fragment within the hemagglutinin gene. The analytical sensitivity of the new assay was measured with serial dilutions of a plasmid that contained the target sequence, and we determined that down to one copy per reaction of the plasmid was reliably detected. Diagnostic performance was assessed with 103 RNAs from suspected cases (40 positive and 63 negative results) previously analyzed with a reference real-time PCR technique. All positive cases were confirmed, and no false-positive results were detected with the new assay. No cross-reactions were observed when other viral strains or clinical samples with other respiratory viruses were tested. According to these results, this new assay has 100% sensitivity and specificity. The turnaround time for the whole procedure was 140 min. The assay may be especially useful for the specific detection of 2009 H1N1 virus in laboratories not equipped with real-time PCR instruments.

Distribution of Toscana virus (TOSV) is evolving with climate change, and pathogenicity may be higher in nonexposed populations outside areas of current prevalence (Mediterranean Basin). To characterize genetic diversity of TOSV, we determined the coding sequences of isolates from Spain and France. TOSV is more diverse than other well-studied phleboviruses (e.g.,Rift Valley fever virus).

Blindness due to corneal diseases is a common pathology affecting up to 23 million individuals worldwide. The tissue-engineered anterior human cornea, which is currently being tested in a Phase I/II clinical trial to treat severe corneal trophic ulcers with preliminary good feasibility and safety results. This bioartificial cornea is based on a nanostructured fibrin-agarose biomaterial containing human allogeneic stromal keratocytes and cornea epithelial cells, mimicking the human native anterior cornea in terms of optical, mechanical, and biological behavior. This product is manufactured as a clinical-grade tissue engineering product, fulfilling European requirements and regulations. The clinical translation process included several phases: an initial in vitro and in vivo preclinical research plan, including preclinical advice from the Spanish Medicines Agency followed by additional preclinical development, the adaptation of the biofabrication protocols to a good manufacturing practice manufacturing process, including all quality controls required, and the design of an advanced therapy clinical trial. The experimental development and successful translation of advanced therapy medicinal products for clinical application has to overcome many obstacles, especially when undertaken by academia or SMEs. We expect that our experience and research strategy may help future researchers to efficiently transfer their preclinical results into the clinical settings.

OBJECTIVES: To compare clinical outcomes in older patients with acute medical crises attended by a geriatrician-led home hospitalization unit (HHU) vs an inpatient intermediate-care geriatric unit (ICGU) in a post-acute care setting. DESIGN: Quasi-experimental longitudinal study, with 30-day follow-up. PARTICIPANTS: Older patients with chronic conditions attended at the emergency department or day hospital for an acute medical crisis. INTERVENTIONS: Patients were referred to geriatrician-led HHU or ICGU wards. SETTING: An acute care hospital, an intermediate care hospital, and the community of an urban area in the North of Barcelona, in Southern Europe. MEASUREMENTS: We compared health crisis outcomes (recovery from the acute health crisis, referral to an acute hospital, or death), length of stay, relative functional gain (RFG) at discharge, readmission to an acute care unit within 30 days of discharge, and mortality within 30 days of discharge. RESULTS: We included 171 older adults (57 in the HHU and 114 in the ICGU) with complex conditions at risk of negative outcomes. At baseline, HHU patients were significantly younger and less likely to be cognitively impaired and referred from an emergency department. Most patients in both groups recovered from their health crises (91.2% in the HHU group vs 88.6% in the ICGU group, P = .79). No differences were found between the 2 groups in 30-day mortality (8.6% vs 9.6%, P = >.99). There was a trend toward lower 30-day readmission to an acute care unit in the HHU group (10.5% vs 19.3% in the ICGU group, P = .19). HHU patients had higher RFG (mean 0.75 days vs 0.51 in the ICGU group, P = .01), and a longer stay in the unit (9.7 vs 8.2 days in the ICGU group, P < .01). CONCLUSIONS: These preliminary results suggest that the geriatrician-led HHU seems effective in resolving acute medical crises in older patients with chronic disease. Patients attended by the HHU obtained better functional outcomes compared to those from the ICGU, although the groups did have some baseline differences.

A new molecular assay (Viral CNS Flow Chip kit, Master Diagnóstica, Spain) has been developed for the detection of eight viruses causing acute meningitis and encephalitis, i.e. herpes simplex viruses 1-2, varicella zoster virus, human enterovirus, human parechovirus, Toscana virus, human cytomegalovirus and Epstein Barr virus. The new assay is a multiplex one-step RT-PCR followed by automatic flow-through hybridization, colorimetric detection and image analysis. The limit of detection was 50 copies/reaction, and 10 copies/reaction for human enterovirus and the other seven viruses, respectively. The analytical validation was performed with nucleic acids extracted from 268 cerebrospinal fluid samples and the results were compared with routine molecular assays. An excellent coefficient of agreement was observed between V-CNS and routine assays [kappa index: 0.948 (95%CI: 0.928-0.968)]. The overall sensitivity and specificity was 95.9% (95%CI: 91.2-98.3%) and 99.9% (95%CI: 99.6-100%), respectively. Viral CNS Flow Chip kit is an efficient multiplex platform for the detection of the main viruses involved in acute meningitis and encephalitis. The inclusion of a TOSV genome target may improve the laboratory diagnosis of viral neurological infections in endemic areas.

The analytical performance of mariPOC® respi test (ArcDia® Laboratories, Turku, Finland) was evaluated using nucleic acid amplification techniques (NAATs) as the gold standard. The mariPOC assay allows automated detection of antigens from 8 respiratory viruses: influenza A and B viruses, respiratory syncytial virus, adenovirus, human metapneumovirus, and parainfluenza viruses 1-3. Positive results from samples with high viral load are available in 20min. Nasopharyngeal aspirates (n=192) from patients with acute respiratory infection and from previously positive samples were analyzed by mariPOC and NAATs (Simplexa(TM) FluA/FluB & RSV kit [n=118] and Luminex® Respiratory virus panel xTAG® RVP FAST [n=74]). Sensitivity, specificity, positive predictive value, and negative predictive value of mariPOC were 85.4%, 99.2%, 95.9%, and 97%, respectively, and 84.6% of positive results were reported in 20min. The good analytical performance and extended portfolio of mariPOC show this rapid assay as a good alternative for the etiological diagnosis of acute respiratory infection in laboratories that are not equipped with molecular assays.
