RESUMO

PurposeThis paper aims to simulate the potential impact of increasing non-performing loans (NPLs) on capital adequacy, interest income and firm value of banks and credit unions in the Eastern Caribbean Currency Union (ECCU) using stress tests. Design/methodology/approachA financial stress testing model was deployed at the levels of individual financial intermediary (FI), sectoral loan portfolio composition, individual member country, and the ECCU collectively, to investigate the impact of NPL shocks on FI stability. FindingsThe authors find that shocks impact the capital adequacy of banks less than that of credit unions, but that firm value of banks is more susceptible to increases in NPLs. Interest income responses to NPL shocks were linked to credit exposure from the tourism sector, which also reduced capital adequacy more than other economic sectors. Findings show that while the COVID-19 pandemic occasioned some increase in NPLs, the magnitude of impact was significantly mitigated by pro-stability policies including loan repayment moratoria and restructuring, guidance on the distribution of profits and deleveraging by financial institutions leading up to 2020. Originality/valueThe paper is among the first to use stress testing on the Caribbean in response to the COVID-19 pandemic. Past studies which have used stress test models in the region have not explicitly investigated the impact of credit shocks on risk-weighted assets or interest income as done herein, nor do they include credit unions in the modeling. The results offer novel evaluations as well as implications for FIs in other developing economies, especially those that share a comparable financial and economic architecture.

RESUMO

BACKGROUND: Adolescents experience a host of sexual and reproductive health (SRH) challenges, with detrimental SRH and socio-economic consequences. These include early sexual debut, sexually transmitted infections including HIV/AIDS, teenage pregnancy, and early childbearing. Parent-adolescent communication about SRH has significant potential to reduce adolescents' risky sexual behaviors. However, communication between parents and adolescents is limited. This study explored the facilitators and barriers to parent-adolescent communication about sexual and reproductive health. METHODS: We conducted a qualitative study in the border districts of Busia and Tororo in Eastern Uganda. Data collection entailed 8 Focus Group Discussions comprising of parents, adolescents (10-17 years), and 25 key informants. Interviews were audio-recorded, transcribed, and translated into English. Thematic analysis was conducted with the aid of NVIVO 12 software. RESULTS: Participants acknowledged the key role parents play in communicating SRH matters; however, only a few parents engage in such discussions. Facilitators of parent-adolescent communication were: having a good parent-child relationship which makes parents approachable and motivates children to discuss issues openly, a closer bond between mothers and children which is partly attributed to gender roles and expectations eases communication, and having parents with high education making them more knowledgeable and confident when discussing SRH issues with children. However, the discussions are limited by cultural norms that treat parent-child conversations on SRH as a taboo, parents' lack of knowledge, and parents busy work schedules made them unavailable to address pertinent SRH issues. CONCLUSION: Parents' ability to communicate with their children is hindered by cultural barriers, busy work schedules, and a lack of knowledge. Engaging all stakeholders including parents to deconstruct sociocultural norms around adolescent SRH, developing the capacity of parents to confidently initiate and convey accurate SRH information, initiation of SRH discussions at early ages, and integrating parent-adolescent communication into parenting interventions, are potential strategies to improve SRH communication between parents and adolescents in high-risk settings such as borders.

RESUMO

Availability of COVID-19 mRNA vaccine for patients with chronic inflammatory demyelinating polyneuropathy (CIDP) treated with intravenous immunoglobulin (IVIg) raises the question of whether COVID-19 mRNA vaccine influences disease activity or IVIg-mediated immunomodulation in CIDP. In this exploratory study, blood samples of CIDP patients on IVIg treatment were longitudinally analyzed before and after vaccination with a COVID-19 mRNA vaccine. A total of 44 samples of eleven patients were characterized at four timepoints by ELISA and flow cytometry in terms of immunomarkers for disease activity and IVIg-immunomodulation. Apart from a significantly lower expression of CD32b on naïve B cells after vaccination, no significant alteration of immunomarkers for CIDP or IVIg-mediated immunomodulation was observed. Our exploratory study suggests that COVID-19 mRNA vaccine does not have a relevant impact on immune activity in CIDP. In addition, immunomodulatory effects of IVIg in CIDP are not altered by COVID-19 mRNA vaccine. This study was registered in the German clinical trial register (DRKS00025759). Overview over the study design. Blood samples of CIDP patients on recurrent IVIg treatment and vaccination with a COVID-19 mRNA vaccine were obtained at four timepoints for cytokine ELISA and flow cytometry, to assess key cytokines and cellular immunomarkers for disease activity and IVIg-immunomodulation in CIDP.

RESUMO

The study investigates the moderating role of students' vitality on the nexus between university support and online learning engagement among tertiary students during the era of Covid-19 pandemic. A sample of 310 business students chosen randomly completed a self-reported questionnaire for the research. Data processing and analysis were done using Statistical Package for the Social Sciences (SPSS) version 24 and SmartPLS 3.3.9, respectively. Results reveal that university support positively and significantly predict students' online learning engagement. Furthermore, students' vitality enhances the positive effect of university support on students' online learning engagement. This study appears to be one of the first to have investigated a model linking university support, online learning engagement and student vitality from the perspective of higher institutions of learning. The findings suggest higher education managers must build students' states of vitality in order to enhance their online learning engagement during periods of pandemic.

RESUMO

Objective To demonstrate a case of suspected post-vaccine autoimmune encephalitis associated with leucine-rich glioma-inactivated protein (LGI1) antibodies with significant clinical improvement after initiation of immunotherapy nearly a year after symptom onset. Background Although the autoimmune encephalitides have overlap in presentation, some have unique manifestations (such as orofacial dyskinesias seen with NMDA encephalitis). These unique associations can serve as a clinical marker of response to treatment and even allow for earlier initiation of immunotherapy while awaiting results from antibody testing. LGI1 encephalitis characteristically presents with faciobrachial dystonic seizures (FBDS) that are refractory to anti-seizure medications (ASMs) but responsive to immunotherapy. Design/Methods Case report Results A previously healthy and highly independent 89-year-old woman developed what she described as abnormal posturing and spasms of the right shoulder two to three weeks after receiving the J&J COVID-19 vaccine. The abnormal movements progressed to involve the right side of her face and were refractory to multiple ASMs. EEG captured multiple events without epileptiform correlate. Several months later she developed paranoia, delusions, and hallucinations. Autoimmune encephalopathy panel returned positive for the LGI1-antibody around nine months after the onset of FBDS. Upon our initial exam, she had a fluctuating level of arousal, impaired recall of recent events, and was tangential in conversation. There were frequent, brief, repetitive, dystonic movements of the right side of the face consistent with FBDS. Admission was arranged for immunotherapy (intravenous methylprednisolone and intravenous immunoglobulin). Upon follow-up four weeks later, there was significant improvement in arousal and concentration with resolution of FBDS and delusions. Conclusions This case highlights a classic case of LGI1 encephalitis after vaccination presenting with FBDS and progressive cognitive changes. Despite immunotherapy being delayed, there was marked clinical improvement. It is important to recognize this entity and that it typically has a favorable outcome.

RESUMO

Ophthalmology faces many challenges in providing effective and meaningful eye care to an ever-increasing group of people. Even health systems that have so far been able to cope with the quantitative patient increase, due to their funding and the availability of highly qualified professionals, and improvements in practice routine efficiency, will be pushed to their limits. Further pressure on care will also be caused by new active substances for the largest group of patients with AMD, the so-called dry form. Treatment availability for this so far untreated group will increase the volume of patients 2-3 times. Without the adaptation of the care structures, this quantitative and qualitative expansion in therapy will inevitably lead to an undersupply.There is increasing scientific evidence that significant efficiency gains in the care of chronic diseases can be achieved through better networking of stakeholders in the healthcare system and greater patient involvement. Digitalization can make an important contribution here. Many technological solutions have been developed in recent years and the time is now ready to exploit this potential. The exceptional setting during the SARS-CoV-2 pandemic has shown many that new technology is available safely, quickly, and effectively. The emergency has catalyzed innovation processes and shown for post-pandemic time after that we are equipped to tackle the challenges in ophthalmic healthcare - ultimately for the benefit of patients and society.

RESUMO

Background Sleep disturbance is common following hospitalisation both for COVID-19 and other causes. The clinical associations are poorly understood, despite it altering pathophysiology in other scenarios. We, therefore, investigated whether sleep disturbance is associated with dyspnoea along with relevant mediation pathways. Methods Sleep parameters were assessed in a prospective cohort of patients (n=2,468) hospitalised for COVID-19 in the United Kingdom in 39 centres using both subjective and device-based measures. Results were compared to a matched UK biobank cohort and associations were evaluated using multivariable linear regression. Findings 64% (456/714) of participants reported poor sleep quality; 56% felt their sleep quality had deteriorated for at least 1-year following hospitalisation. Compared to the matched cohort, both sleep regularity (44.5 vs 59.2, p<0.001) and sleep efficiency (85.4% vs 88.5%, p<0.001) were lower whilst sleep period duration was longer (8.25h vs 7.32h, p<0.001). Overall sleep quality (effect estimate 4.2 (3.0-5.5)), deterioration in sleep quality following hospitalisation (effect estimate 3.2 (2.0-4.5)), and sleep regularity (effect estimate 5.9 (3.7-8.1)) were associated with both dyspnoea and impaired lung function (FEV1 and FVC). Depending on the sleep metric, anxiety mediated 13-42% of the effect of sleep disturbance on dyspnoea and muscle weakness mediated 29-43% of this effect. Interpretation Sleep disturbance is associated with dyspnoea, anxiety and muscle weakness following COVID-19 hospitalisation. It could have similar effects for other causes of hospitalisation where sleep disturbance is prevalent.

RESUMO

Background Nottinghamshire Hospice's day therapy unit closed its doors to patients during the COVID-19 pandemic. Government advice was supporting discharge from hospital wherever possible (NHS England and NHS Improvement, 2020). When asked, more than four in five people say they would prefer to die at home (Hoare, Morris, Kelly, et al., 2015). Patients receiving care from specialist palliative care teams tend to do better than those without (Higginson & Evans, 2010). Aims To expedite the discharge of patients at end-of-life from hospital and prevent unnecessary hospital admission for those in the community so that more people achieve their preferred place of death (PPD) with the provision of a dedicated palliative care service. Methods March-May 2020: consultations with fast track continuing care (FTCC), model planning, internal consultation, workforce transformation. May-July 2020: recruitment, service launch. July-March 2021: continuous service provision. We worked closely alongside FTCC to support patients either in hospital that wished to come home but needed a package of care or, patients that were deteriorating at home and required end-of-life care. An initial assessment by a registered nurse from the Hospice Outreach Discharge Support (HODS) team meant more timely referral into extended palliative community services including provision of specialist equipment and access to other hospice services e.g. bereavement support. It also focuses on the completion of EPaCCS and ReSPECT forms identifying PPD. Results Number of patients treated by HODS May 20 - March 21 = 195. 64% (124) died at home. 23% (44) remained well enough to be discharged to domiciliary care agency. 10% (20) admitted to hospital. 3% (6) admitted to nursing home. Average length of stay on HODS = 10 days PPD achieved = 95.87% [4] Conclusion The creation of HODS allows more people at end-of-life to remain in their PPD and with greater access to support services preventing carer burnout and unnecessary admission to hospital.

RESUMO

The global emergence of coronavirus disease 2019 (COVID-19) has caused substantial human casualties. Clinical manifestations of this disease vary from asymptomatic to lethal, and the symptomatic form can be associated with cytokine storm and hyperinflammation. In face of the urgent demand for effective drugs to treat COVID-19, we have searched for candidate compounds using in silico approach followed by experimental validation. Here we identified celastrol, a pentacyclic triterpene isolated from Tripterygium wilfordii Hook F, as one of the best compounds out of 39 drug candidates. Celastrol reverted the gene expression signature from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected cells and irreversibly inhibited the recombinant forms of the viral and human cysteine proteases involved in virus invasion, such as Mpro (main protease), PLpro (papain-like protease), and recombinant human cathepsin L. Celastrol suppressed SARS-CoV-2 replication in human and monkey cell lines and decreased interleukin-6 (IL-6) secretion in the SARS-CoV-2-infected human cell line. Celastrol acted in a concentration-dependent manner, with undetectable signs of cytotoxicity, and inhibited in vitro replication of the parental and SARS-CoV-2 variant. Therefore, celastrol is a promising lead compound to develop new drug candidates to face COVID-19 due to its ability to suppress SARS-CoV-2 replication and IL-6 production in infected cells.

RESUMO

Introduction:Mental health conditions such as anxiety represent a growing health concern for students in institutions of higher education. Postsecondary students are a vulnerable population that is increasingly recognized to be at risk for both mental health problems and significant sleep problems. While it has been hypothesized that poor sleep quality may be a risk factor for developing anxiety, little is known about the frequency and severity of sleep problems and their association with anxiety within the postsecondary student population. The aim of this systematic review was to synthesize the best evidence on the association between sleep quality and anxiety in postsecondary students. Materials and Methods: An experienced librarian developed systematic search strategies in four databases: MEDLINE, Embase, APA PsycInfo (through Ovid Technologies Inc.) and CINAHL, Cumulative Index to Nursing and Allied Health Literature (through EBSCOhost). Databases were searched from inception to September 2020. Random pairs of independent reviewers screened titles and s for eligibility and critically appraised all eligible studies. We assessed the quality of studies using the Scottish Intercollegiate Guidelines Network (SIGN) criteria for cohort studies, and the Hoy tool for cross-sectional studies. One author extracted and synthesized the results from all of the low and moderate risk of bias studies. We synthesized our results by study design and population. Results: Once duplicates were removed, a total of 3203 unique citations were screened. Fifty-one articles were eligible and critically appraised. Studies with low and moderate risk of bias were included in our final synthesis of which 24 were cross-sectional studies and four were cohort studies. With the exception of one study, all cross-sectional studies reported a statistically significant association between poor sleep quality and anxiety. All four of the cohort studies found that students who reported poor sleep quality were more likely to develop future anxiety and students with anxiety were more likely to develop future poor sleep quality. Conclusions: Poor sleep quality is associated with anxiety in postsecondary students. Due to the cross-sectional nature of most studies, we cannot determine the direction of this association. Future studies should focus on developing high-quality prospective cohort or longitudinal studies to help understand the impact and direction that this association has in postsecondary populations. This research has the potential to inform the development and design of mental health policies and programs that are created by postsecondary institutions to address the increasing rates of student mental health issues.

RESUMO

Introduction: Students pursuing postsecondary education are a population at significant risk for both sleep problems and poor mental health outcomes such as depression and anxiety. Interventions such as sleep hygiene education and cognitive behavioural therapy (CBT) are commonly used treatments for sleep problems and have been effective in improving sleep and mental health in the university student population. Digitally-delivered CBT has also been shown to be effective in improving sleep in youth, however it has not been evaluated in the postsecondary student population. Materials and Methods: We conducted a systematic review of the quantitative and qualitative evidence on the effectiveness and user experiences of digital sleep interventions to improve sleep and mental health outcomes in postsecondary students. We searched MEDLINE, CINAHL, Embase, and APA PsycInfo for studies published from 2000 to 2021. We included randomized controlled trials (RCTs), cohort studies, case-control studies, qualitative studies, and mixed methods studies. Pairs of reviewers independently screened and critically appraised studies, and extracted data. We aimed to use a sequential approach at the review level to synthesize and integrate data across qualitative and quantitative research studies. Results: We screened 5361 citations and 58 full text articles. Eight relevant RCTs and one cohort study were critically appraised. Three interventions were assessed including CBT, digital sleep hygiene education, and relaxation music. Most studies were assessed as high risk of bias. Given the methodological limitations of the included studies, we are unable to conclude on the effectiveness of digital sleep interventions for postsecondary students. We did not identify any qualitative studies. Conclusions: Methodological limitations preclude firm conclusions. Further research is needed to assess the effectiveness of digital alternatives for delivering sleep interventions to improve sleep and mental health outcomes in postsecondary students. Qualitative studies exploring the views and preferences of students and providers are required to inform the development of novel interventions that are acceptable in this population.

RESUMO

BACKGROUND AND PURPOSE: This study assessed the prevalence of anti-SARS-CoV-2 antibodies in therapeutic immunoglobulin and their impact on serological response to COVID-19 mRNA vaccine in patients with intravenous immunoglobulin (IVIg)-treated chronic immune neuropathies. METHODS: Forty-six samples of different brands or lots of IVIg or subcutaneous IgG were analyzed for anti-SARS-CoV-2 IgG using enzyme-linked immunosorbent assay and chemiluminescent microparticle immunoassay. Blood sera from 16 patients with immune neuropathies were prospectively analyzed for anti-SARS-CoV-2 IgA, IgG, and IgM before and 1 week after IVIg infusion subsequent to consecutive COVID-19 mRNA vaccine doses and after 12 weeks. These were compared to 42 healthy subjects. RESULTS: Twenty-four (52%) therapeutic immunoglobulin samples contained anti-SARS-CoV-2 IgG. All patients with immune neuropathies (mean age = 65 ± 16 years, 25% female) were positive for anti-SARS-CoV-2 IgG after COVID-19 vaccination. Anti-SARS-CoV-2 IgA titers significantly decreased 12-14 weeks after vaccination (p = 0.02), whereas IgG titers remained stable (p = 0.2). IVIg did not significantly reduce intraindividual anti-SARS-CoV-2 IgA/IgG serum titers in immune neuropathies (p = 0.69). IVIg-derived anti-SARS-CoV-2 IgG did not alter serum anti-SARS-CoV-2 IgG decrease after IVIg administration (p = 0.67). CONCLUSIONS: Our study indicates that IVIg does not impair the antibody response to COVID-19 mRNA vaccine in a short-term observation, when administered a minimum of 2 weeks after each vaccine dose. The infusion of current IVIg preparations that contain anti-SARS-CoV-2 IgG does not significantly alter serum anti-SARS-CoV-2 IgG titers.

RESUMO

Objective We explain evolving policy choices made by all 50 states in response to the coronavirus (COVID-19) pandemic in the United States against the background of each state's political and public health landscape. Method We create an index of eight state preventative measures and explain variation in that index by infection and death rates, vaccination rates, support for President Trump in 2020, and the political party of the governor. We control for population density and the health vulnerability of each state. Results State response was largely driven by three factors: the death rate from COVID-19, Trump votes in 2020 and Republican control of the governorship. Conclusion Understanding state response to the pandemic requires going beyond a partisan lens and considering the shifting onus of responsibility for taking action to protect against the virus from states to individual citizens in an increasingly politicized sphere of pandemic response.

RESUMO

Background While the corona pandemic and the resulting containment measures affect the number of elective surgical procedures, the impact on emergency surgical interventions is less tangible. This analysis quantifies the frequency of emergency vitrectomies for retinal detachment and investigates underlying factors. Methods Retrospective identification of patients who underwent primary emergency vitrectomies for retinal detachment at the Cantonal Hospital of Lucerne between 01.01.2018 – 31.12.2020. Parameters were collected, including demographics, date of hospitalisation, reported onset of symptoms, pre-operative best corrected visual acuity (BCVA), involvement of the macula, and canton of residence. Results Overall, a total of 665 patients with 683 eyes underwent emergency surgery for primary retinal detachment in the time span of 01.01.2018 – 31.12.2020. Median monthly number of surgeries was 20. During the first Swiss national lockdown (16.03.2020 – 19.04.2020), a minimum of 9 vitrectomies was recorded in March 2020. A maximum of 36 vitrectomies was conducted in August 2020. The mean age of patients was 61.5 years. Of the 665 patients, 133 (20.0%) were residents of the canton of Ticino. Median pre-operative BCVA was 0.25 over all three years, and no significant reduction in pre-operative BCVA was observed during or after the lockdown. The proportion of eyes with involvement of the macula was 52.2%. In 2018, this proportion (47.6%) was significantly lower than in 2019 and 2020 (Chi 2 test, p < 0.001). However, cases with macular involvement in post lockdown months were not more frequent. Median time in days from reported symptom onset to hospitalisation was 5 days. In April 2020, the proportion of patients with > 14 days symptom duration was significantly higher (Chi 2 test, p < 0.001). During the lockdown, there was a significant reduction in cases from Ticino. Also, patients from Ticino showed proportionally longer symptom duration after the lockdown. Conclusion A significant reduction in the number of emergency vitrectomies was observed for the initial period of the coronavirus pandemic. Delayed emergency presentation is not assumed, since there was no increase in severity (i.e. macular involvement) or prolonged symptoms in the months following the lockdown. More protracted symptoms were only observed in patients from Ticino. The initial low numbers were generally made good later in the year.

RESUMO

Type I interferons (IFN-I) play a critical role in human antiviral immunity, as demonstrated by the exceptionally rare deleterious variants of IFNAR1 or IFNAR2. We investigated five children from Greenland, Canada, and Alaska presenting with viral diseases, including life-threatening COVID-19 or influenza, in addition to meningoencephalitis and/or hemophagocytic lymphohistiocytosis following live-attenuated viral vaccination. The affected individuals bore the same homozygous IFNAR2 c.157T>C, p.Ser53Pro missense variant. Although absent from reference databases, p.Ser53Pro occurred with a minor allele frequency of 0.034 in their Inuit ancestry. The serine to proline substitution prevented cell surface expression of IFNAR2 protein, small amounts of which persisted intracellularly in an aberrantly glycosylated state. Cells exclusively expressing the p.Ser53Pro variant lacked responses to recombinant IFN-I and displayed heightened vulnerability to multiple viruses in vitro-a phenotype rescued by wild-type IFNAR2 complementation. This novel form of autosomal recessive IFNAR2 deficiency reinforces the essential role of IFN-I in viral immunity. Further studies are warranted to assess the need for population screening.

RESUMO

Purpose: COVID-19 has caused a shift toward consumer-facing technology such as mobile health (mHealth) applications. However, most mHealth apps do not use accessible language. Standardized terminologies have potential to solve this problem but have not been simplified for consumer use. Methods: We used a standardized health terminology, the Omaha System, as the framework to develop the Simplified Omaha System Terms (SOST) for use within a mHealth application, MyStrengths + MyHealth. Plain language principles informed the SOST development in three phases, a community-validation focus group enabled feedback from diverse end-users, a readability assessment provide validation to the desired goal readability level. Results: The community-validation members (n = 19) ages ranged from 22 to 74;51% male, 84% people of color, and 21% college educated. The reading level of the final SOST averaged 3.86 on the Coleman–Liau Index (fourth grade). A case study showed meaningful whole-person health data were generated in a community-led study during COVID-19. Conclusions: Community validation and readability assessment demonstrated accessible language for a clinical terminology. The SOST was deployed successfully in MyStrengths + My Health and in a community-led study. The Omaha System as a framework for the SOST may enable the data to be integrated with clinical datasets. Future research should focus on validation of SOST in additional languages and integration within electronic health platforms. © 2022 The Authors.
