Principais motivos de descarte de córneas para transplante na Paraíba: por que o anti-HBc merece atenção?* / Main reasons for discarding corneas for transplant in Paraíba: why does anti-HBc deserve attention?*

RESUMO Objetivo: Identificar o perfil dos doadores de tecidos oculares humanos na área de atuação do Banco de Olhos da Paraíba, destacando o impacto da sorologia positiva para hepatite B no descarte dos tecidos para transplante. Métodos: O estudo é transversal e utilizou dados do Banco de Olhos da Paraíba entre janeiro de 2013 e dezembro de 2022. Dados sobre procedência, idade, sexo, causa do óbito, tempo entre óbito e enucleação, resultados sorológicos e motivo de descarte das córneas dos doadores foram coletados. Resultados: O maior motivo de descarte foi por sorologia positiva (56,5%), sendo positivadas as sorologias positivas para hepatite B e HBsAg em 11,1% e 4,75% dos pacientes, respectivamente. Conclusão: A sorologia positiva para hepatite B como um critério de descarte absoluto é responsável por grande parcela de descartes, apesar da pouca informação sobre suas repercussões e representação de infectividade nos receptores do transplante.

ABSTRACT Objective: To identify the profile of human ocular tissue donors in the area covered by the Eye Bank of Paraíba (PB), highlighting the impact of positive serology for hepatitis B (anti-HBc) in the disposal of tissues for transplantation. Methods: This is a cross-sectional that uses data from the Eye Bank of Paraíba (PB) between January 2013 and December 2022. Data on origin, age, sex, cause of death, time between death and enucleation, serological results, and reason for discarded donor corneas were collected. Results: The main reason for discarding was due to positive serology (56.5%), with positive anti-HBc and HBsAg serology in 11.1% and 4.75% of patients, respectively. Conclusion: Anti-HBc positive serology as an absolute disposal criterion is responsible for great part of disposals, despite little information about its repercussions and representation of infectivity in transplant recipients.

Barriers and facilitators to implementing telehealth services during the COVID-19 pandemic: A qualitative analysis of interviews with cystic fibrosis care team members.

BACKGROUND: The COVID-19 pandemic forced cystic fibrosis (CF) care programs to rapidly shift from in-person care delivery to telehealth. Our objective was to provide a qualitative exploration of facilitators and barriers to: 1) implementing high-quality telehealth and 2) navigating reimbursement for telehealth services. METHODS: We used data from the 2020 State of Care CF Program Survey (n=286 U.S. care programs) administered in August-September to identify two cohorts of programs, with variation in telehealth quality (n=12 programs) and reimbursement (n=8 programs). We conducted focus groups and semi-structured interviews with CF program directors and coordinators in December 2020, approximately 9 months from onset of the pandemic. We used the Consolidated Framework for Implementation Research to identify facilitators and barriers of implementation, and inductive thematic analysis to identify facilitators and barriers of reimbursement. RESULTS: Factors differentiating programs with greater and lower perceived telehealth quality included telehealth characteristics (perceived advantage over in-person care, cost, platform quality); external influences (needs and resources of those served by the CF program), characteristics of the CF program (compatibility with workflows, relative priority, available resources); characteristics of team members (individual stage of change), and processes for implementation (engaging patients and teams). Reimbursement barriers included documentation to optimize billing; reimbursement of multi-disciplinary team members, remote monitoring, and telephone-only telehealth; and lower volume of patients. CONCLUSIONS: A number of factors are associated with successful implementation and reimbursement of telehealth. Future efforts should provide guidance and incentives that support telehealth delivery and infrastructure, share best practices across CF programs, and remove barriers.

Patient and family experience of telehealth care delivery as part of the CF chronic care model early in the COVID-19 pandemic.

BACKGROUND: During the COVID-19 pandemic, CF centers shifted to a telehealth delivery model. Our study aimed to determine how people with CF (PwCF) and their families experienced telehealth and assessed its quality and acceptability for future CF care. METHODS: The CF Patient and Family State of Care Survey (PFSoC) was fielded from August 31-October 30, 2020. The PFSoC explored themes of overall telehealth quality, ease of use, desirability, and preference for a future mix of in-person and telehealth care. Demographic covariates considered included: gender, age, CFTR modulator status, and region of residence. RESULTS: 424 PwCF and parents of PwCF responded (47% parents). Most (81%) reported a telehealth visit which included a MD/APP and nurse team members. 91% found telehealth easy to use, and 66% reported similar/higher quality than in-person care. One-third (34%) reported the highest desire for future telehealth care, with 45% (n =212) desiring 50% or more of visits conducted via telehealth. Adults were more likely than parents to report highest desire for future telehealth (64% vs. 36%). Respondents who perceived telehealth as similar/higher quality were more likely to desire future telehealth compared to those who perceived telehealth as lower quality (96% vs. 50%). Mixed methods analysis revealed themes affecting perceptions of telehealth. CONCLUSIONS: PwCF desire for future telehealth was influenced by perception of quality and age. Several themes emerged that need to be explored as telehealth is adapted into the CF chronic care model, especially when thinking about integration into pediatric care.

Evaluating barriers to and promoters of telehealth during the COVID-19 pandemic at U.S. cystic fibrosis programs.

BACKGROUND: Cystic fibrosis (CF) care programs in the United States rapidly adopted telehealth during the COVID-19 pandemic. Understanding factors that promote or impede telehealth will inform planning for future telehealth-enabled care models. METHODS: Adult, pediatric, and affiliate CF care programs in the United States (n = 287) were surveyed twice eight months apart in 2020-2021 about telehealth use. Programs were asked to describe barriers to and promoters of telehealth. RESULTS: Ninety-seven percent of programs provided telehealth services. In the first CF Care Program State of Care Survey (SoC1), programs estimated that 57% of patients exclusively received in-person care, 36% of patients received telehealth by phone/computer with video, and 8% of patients received telephone-only care. In the second CF Care Program State of Care Survey (SoC2), programs estimated that 80% of visits were in-person and 15% were via audio and video telehealth. Pediatric programs (21%) were less likely than adult (37%) or affiliate (41%) programs to recommend telehealth (p = 0.007). All programs ranked lack of internet access as the highest barrier to patient engagement with telehealth. Promoters of telehealth were increased accessibility and avoidance of infection transmission. Top ranked changes to improve telehealth were expanded provision of remote monitoring devices and technology access. Similar proportions of program types anticipated institutional telehealth expansion. CONCLUSION: During the COVID-19 pandemic, CF programs in the United States identified factors to improve future care delivery via telehealth. Targeting specific barriers and promoters will improve the use and quality of telehealth throughout the care center network.

Adapting Surgical Clerkship Curricula in Response to the COVID-19 Pandemic.

BACKGROUND: Coronavirus disease-19 (COVID-19) impacted medical education and led to the significant modification or suspension of clinical clerkships and rotations. OBJECTIVES: To describe a revised surgery clerkship curriculum, in which we divided in-person clinical teaching into smaller groups of students and adopted online-based learning to foster student and patient safety while upholding program standards. METHODS: The third-year surgery core clerkship of a 4-year international English-language program at the Medical School for International Health at Ben Gurion University of the Negev, Beer Sheva, Israel, was adapted by dividing students into smaller capsules for in-person learning and incorporating online learning tools. Specifically, students were divided evenly throughout three surgical departments, each of which followed a different clinical schedule. RESULTS: National Board of Medical Examiners clerkship scores of third-year medical students who were returning to in-person clinical clerkships after transitioning from 8 weeks of online-based learning showed no significant difference from the previous 2 years. CONCLUSIONS: To manage with the restrictions caused by COVID-19 pandemic, we designed an alternative approach to a traditional surgical clerkship that minimized the risk of exposure and used online learning tools to navigate scheduling challenges. This curriculum enabled students to complete their clinical rotation objectives and outcomes while maintaining program standards. Furthermore, this approach provided a number of benefits, which medical schools should consider adopting the model into practice even in a post-pandemic setting.

Recommendations for Orthopedic Surgeons during the COVID-19 Pandemic.

BACKGROUND: Toward the end of 2019, the coronavirus disease-2019 (COVID-19) pandemic began to create turmoil for global health organizations. The illness, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), spreads by droplets and fomites and can rapidly lead to life-threatening lung disease, especially for the old and those with health co-morbidities. Treating orthopedic patients, who presented with COVID-19 while avoiding nosocomial transmission, became of paramount importance. OBJECTIVES: To present relevant methods for pandemic control and hospital accommodation with emphasis on orthopedic surgery. METHODS: We searched search PubMed and Google Scholar electronic databases using the following keywords: COVID-19, SARS-CoV-2, screening tools, personal protective equipment, and surgery triage. RESULTS: We included 25 records in our analysis. The recommendations from these records were divided into the following categories: COVID-19 disease, managing orthopedic surgery in the COVID-19 era, general institution precautions, triage of orthopedic surgeries, preoperative assessment, surgical room setting, personal protection equipment, anesthesia, orthopedic surgery technical precautions, and department stay and rehabilitation. CONCLUSIONS: Special accommodations tailored for each medical facility, based on disease burden and available resources can improve patient and staff safety and reduce elective surgery cancellations. This article will assist orthopedic surgeons during the COVID-19 medical crisis, and possibly for future pandemics.

Online residency training during the COVID-19 pandemic: a national survey of otolaryngology head and neck surgery program directors.

BACKGROUND: The COVID-19 pandemic has deeply impacted healthcare and education systems, including resident education. The impact of the pandemic on the different types of pedagogical activities, and the displacement of pedagogical activities to online modalities have not yet been quantified. We sought to evaluate the impact of the COVID-19 pandemic on formal pedagogic components of otorhinolaryngology-head and neck surgery (ORL-HNS) residency, the switch to distance learning and program director's perceptions of the future of teaching and learning. METHODS: A nationwide online survey was conducted on Canadian ORL-HNS program directors. The use of standard didactic activities in-person and online, before and during the pandemic was rated with Likert scales. Perceptions of the pandemic were described with open-ended questions. RESULTS: A total of 11 of the 13 program directors contacted responded. The analysis were conducted using nonparametric statistics. There was a significant drop in overall didactic activities during the pandemic, regardless of the teaching format (3.5 ± 0.2 to 3.1 ± 0.3, p < 0.05). The most affected activities were simulation and in-house lectures. Online activities increased dramatically (0.5 ± 0.2 to 5.0 ± 0.5, p < 0.001), including attendance to lectures made by other programs (0.5 ± 0.3 to 4.0 ± 0.8, p < 0.05). Respondents stated their intention to maintain the hybrid online and in-person teaching model. CONCLUSIONS: These findings suggest that hybrid online and in-person teaching is likely to persist in the post-pandemic setting. A balanced residency curriculum requires diversity in academic activities. The pandemic can have positive consequences if higher education institutions work to better support distance teaching and learning.

Supplemental findings of the 2019 National Blood Collection and Utilization Survey.

INTRODUCTION: Supplemental data from the 2019 National Blood Collection and Utilization Survey (NBCUS) are presented and include findings on donor characteristics, autologous and directed donations and transfusions, platelets (PLTs), plasma and granulocyte transfusions, pediatric transfusions, transfusion-associated adverse events, cost of blood units, hospital policies and practices, and implementation of blood safety measures, including pathogen reduction technology (PRT). METHODS: National estimates were produced using weighting and imputation methods for a number of donors, donations, donor deferrals, autologous and directed donations and transfusions, PLT and plasma collections and transfusions, a number of crossmatch procedures, a number of units irradiated and leukoreduced, pediatric transfusions, and transfusion-associated adverse events. RESULTS: Between 2017 and 2019, there was a slight decrease in successful donations by 1.1%. Donations by persons aged 16-18 decreased by 10.1% while donations among donors >65 years increased by 10.5%. From 2017 to 2019, the median price paid for blood components by hospitals for leukoreduced red blood cell units, leukoreduced apheresis PLT units, and for fresh frozen plasma units continued to decrease. The rate of life-threatening transfusion-related adverse reactions continued to decrease. Most whole blood/red blood cell units (97%) and PLT units (97%) were leukoreduced. CONCLUSION: Blood donations decreased between 2017 and 2019. Donations from younger donors continued to decline while donations among older donors have steadily increased. Prices paid for blood products by hospitals decreased. Implementation of PRT among blood centers and hospitals is slowly expanding.

Predictors of delayed sputum smear conversion among pulmonary tuberculosis patients in Kota Kinabalu, Malaysia: A retrospective cohort study.

ABSTRACT: Smear-positive pulmonary tuberculosis (SPPTB) is the major contributor to the spread of tuberculosis (TB) infection, and it creates high morbidity and mortality worldwide. The objective of this study was to determine the predictors of delayed sputum smear conversion at the end of the intensive phase of TB treatment in Kota Kinabalu, Malaysia.This retrospective study was conducted utilising data of SPPTB patients treated in 5 TB treatment centres located in Kota Kinabalu, Malaysia from 2013 to 2018. Pulmonary TB (PTB) patients included in the study were those who had at least completed the intensive phase of anti-TB treatment with sputum smear results at the end of the 2nd month of treatment. The factors associated with delayed sputum smear conversion were analyzed using multiple logistic regression analysis. Predictors of sputum smear conversion at the end of intensive phase were evaluated.A total of 2641 patients from the 2013 to 2018 periods were included in this study. One hundred eighty nine (7.2%) patients were identified as having delayed sputum smear conversion at the end of the intensive phase treatment. Factors of moderate (advanced odd ratio [aOR]: 1.7) and advanced (aOR: 2.7) chest X-ray findings at diagnosis, age range of >60 (aOR: 2.1), year of enrolment 2016 (aOR: 2.8), 2017 (aOR: 3.9), and 2018 (aOR: 2.8), smokers (aOR: 1.5), no directly observed treatment short-course (DOTS) supervisor (aOR: 6.9), non-Malaysian citizens (aOR: 1.5), and suburban home locations (aOR: 1.6) were associated with delayed sputum smear conversion at the end of the intensive phase of the treatment.To improve sputum smear conversion success rate, the early detection of PTB cases has to be fine-tuned so as to reduce late or severe case presentation during diagnosis. Efforts must also be in place to encourage PTB patients to quit smoking. The percentage of patients assigned with DOTS supervisors should be increased while at the same time ensuring that vulnerable groups such as those residing in suburban localities, the elderly and migrant TB patients are provided with proper follow-up treatment and management.

Assessing COVID-19 Prevention Strategies to Permit the Safe Opening of Residential Colleges in Fall 2021.

BACKGROUND: Effective vaccines, improved testing technologies, and decreases in COVID-19 incidence prompt an examination of the choices available to residential college administrators seeking to safely resume in-person campus activities in fall 2021. OBJECTIVE: To help college administrators design and evaluate customized COVID-19 safety plans. DESIGN: Decision analysis using a compartmental epidemic model to optimize vaccination, testing, and other nonpharmaceutical interventions depending on decision makers' preferences, choices, and assumptions about epidemic severity and vaccine effectiveness against infection, transmission, and disease progression. SETTING: U.S. residential colleges. PARTICIPANTS: Hypothetical cohort of 5000 persons (students, faculty, and staff) living and working in close proximity on campus. MEASUREMENTS: Cumulative infections over a 120-day semester. RESULTS: Under base-case assumptions, if 90% coverage can be attained with a vaccine that is 85% protective against infection and 25% protective against asymptomatic transmission, the model finds that campus activities can be resumed while holding cumulative cases below 5% of the population without the need for routine, asymptomatic testing. With 50% population coverage using such a vaccine, a similar cap on cumulative cases would require either daily asymptomatic testing of unvaccinated persons or a combination of less frequent testing and resumption of aggressive distancing and other nonpharmaceutical prevention policies. Colleges returning to pre-COVID-19 campus activities without either broad vaccination coverage or high-frequency testing put their campus population at risk for widespread viral transmission. LIMITATION: Uncertainty in data, particularly vaccine effectiveness (preventive and transmission); no distinguishing between students and employees; and assumes limited community intermixing. CONCLUSION: Vaccination coverage is the most powerful tool available to residential college administrators seeking to achieve a safe return to prepandemic operations this fall. Given the breadth of potential outcomes in the face of uncontrollable and uncertain factors, even colleges with high vaccination rates should be prepared to reinstitute or expand testing and distancing policies on short notice.

COVID-19 and the Use of Immunomodulatory Agents in Ophthalmology

Immunomodulatory agents are often used in the systemic treatment of non-infectious uveitis. These drugs consist of corticosteroids, conventional immunosuppressives, and biological agents. As it is known that they suppress the immune system, the most important concern associated with immunomodulatory therapy (IMT) is the increased risk of infection. The World Health Organization declared COVID-19 a pandemic on 11 March 2020. Although severe acute respiratory distress syndrome secondary to SARS-CoV-2 infection may develop in all people, patients who receive IMT may be at higher risk in terms of both the transmission of the infection and more severe disease course. Therefore, guidelines on the management of patients receiving IMT due to uveitis during the pandemic are needed. In this review, we examined the immunomodulatory drugs used in the treatment of uveitis in terms of infectious complications and the data of patients who received IMT during the COVID-19 pandemic and discussed recommendations for the use of these drugs. According to the latest information, patients who receive IMT may continue their treatment as long as there are no disruptions in regular complete blood count (especially white blood cell count >4,000/µL) and liver and kidney function tests. Patients diagnosed with COVID-19 should be managed with a multidisciplinary approach.

12 pasos para reducir la incidencia de carbapenemasas / 12 steps to mitigate the incidence of carbapenemases

La resistencia a los antimicrobianos es un grave problema para la salud mundial. Es aún más crítico en los hospitales debido a la aparición de bacterias Gram negativas resistentes a múltiples fármacos, asociadas a una alta mortalidad. Las opciones de tratamiento en estos casos son escasas, en general de alto costo. La alta densidad de consumo de antibióticos y la transmisión cruzada en este entorno amplifican este problema.Hay más evidencia del impacto de las medidas de control de infecciones que de las intervenciones de comités de antimicrobianos para mitigarlo. Además, pocos países cuentan con programas sólidos de control de infecciones para enfrentar este problema. En la presente revisión se propone una serie de 12 pasos a adoptar para mitigar la prevalencia de resistencia antimicrobiana y reducir la incidencia de carbapenemasas en las instituciones de salud. Estas recomendaciones deben interpretase como un ̈bundle ̈o paquete de medidas, en el cual todas son importantes. Aquellas que involucran la prevención de infecciones y/o colonizaciones y su diseminación son las de mayor impacto demostrado hasta ahora. Es esencial que los programas de optimización de uso de antimicrobianos cuenten con el empoderamiento de la conducción de las instituciones donde se lleven a cabo, así como también que estén constituidos por un equipo multidisciplinario eficiente, sólidamente entrenado, con metas y métricas objetivas y auditorias periódicas. También es recomendable que se incluyan recomendaciones para los tratamientos en pacientes en cuidados de fin de vida.

Antimicrobial resistance is a serious global health problem. It is even more critical in hospitals due to the emergence of multi-drug resistant Gram negative bacteria, associated with high mortality. The treatment options in these cases are scarce, generally high cost. The high density of antibiotic consumption and cross-transmission in this environment amplifies this problem.There is more evidence of the impact of Infection Control measures than of Antimicrobial Committee interventions to mitigate it. Furthermore, few countries have solid Infection Control programs to deal with this problem.This review proposes a series of 12 steps to adopt to mitigate the prevalence of antimicrobial resistance and reduce the incidence of carbapenemases in health institutions. These recommendations should be interpreted as a ̈Bundle ̈ or package of measures, in which all are important. Those that involve the prevention of infections and / or colonizations and their dissemination are the ones with the greatest impact demonstrated so far. It is essential that antimicrobial use optimization programs have the empowerment of the leadership of the institutions where they are carried out, as well as that they are constituted by an efficient multidisciplinary team, solidly trained, with objective goals and metrics and periodic audits. It is also recommended that recommendations be included for treatments in patients in end-of-life care.
