Role of previous infection with SARS-CoV-2 in protecting against omicron reinfections and severe complications of COVID-19 compared to pre-omicron variants: a systematic review.

BACKGROUND: The SARS-CoV-2 virus elicited a major public concern worldwide since December 2019 due to the high number of infections and deaths caused by COVID-19. The Omicron variant was detected in October 2021 which evolved from the wild-type SARS-CoV-2 and was found to possess many mutations. Omicron exhibited high transmissibility and immune evasion as well as reduced severity when compared to the earlier variants. Although vaccinated individuals were largely protected against infections in previous waves, the high prevalence of both reinfections and breakthrough infections with Omicron was observed. The aim of this review is to understand the effectiveness of previous infection on subsequent reinfection, given its significance in driving public health policy, including vaccination prioritization and lockdown requirements. METHODS: A comprehensive literature search was conducted using several databases to target studies reporting data related to the effectiveness of the previous infection with SARS-CoV-2 in protecting against the Omicron variant. Screening of the studies, quality assessment and data extraction were conducted by two reviewers for each study. RESULTS: Only 27 studies met our inclusion criteria. It was observed that previous infection was less effective in preventing reinfections with the Omicron variant compared to the Delta variant irrespective of vaccination status. Furthermore, being fully vaccinated with a booster dose provided additional protection from the Omicron variant. Additionally, most infections caused by Omicron were asymptomatic or mild and rarely resulted in hospitalizations or death in comparison to the Delta wave. CONCLUSION: A majority of the studies reached a consensus that although previous infection provides some degree of immunity against Omicron reinfection, it is much lower in comparison to Delta. Full vaccination with two doses was more protective against Delta than Omicron. Receiving a booster dose provided additional protection against Omicron. It is therefore clear that neither vaccination nor previous infection alone provide optimal protection; hybrid immunity has shown the best results in terms of protecting against either Omicron or Delta variants. However, additional research is needed to quantify how long immunity from vaccination versus previous infection lasts and whether individuals will benefit from variant-specific vaccinations to enhance protection from infection.

Cardiovascular and haematological events post COVID-19 vaccination: A systematic review.

Since COVID-19 took a strong hold around the globe causing considerable morbidity and mortality, a lot of effort was dedicated to manufacturing effective vaccines against SARS-CoV-2. Many questions have since been raised surrounding the safety of the vaccines, and a lot of media attention to certain side effects. This caused a state of vaccine hesitancy that may prove problematic in the global effort to control the virus. This review was undertaken with the aim of putting together all the reported cardiovascular and haematological events post COVID-19 vaccination in published literature and to suggest possible mechanisms to explain these rare phenomena.

Lymphadenopathy post-COVID-19 vaccination with increased FDG uptake may be falsely attributed to oncological disorders: A systematic review.

Coronavirus disease 2019 (COVID-19) has caused a global pandemic that continues to cause numerous deaths to date. Four vaccines have been approved by the Food and Drug Administration as of July 2021 to prevent the transmission of COVID-19: Pfizer, Moderna, AstraZeneca, and Janssen. These vaccines have shown great efficacy and safety profile. One side effect that has been widely reported is post-COVID-19 vaccination lymphadenopathy. Due to the mimicry of the lymphadenopathy for metastases in some oncologic patients, there have been reports of patients who underwent biopsies that showed pathologic confirmation of benign reactive lymphadenopathy secondary to the COVID-19 vaccine. Therefore, understanding the incidence of lymphadenopathy post-COVID-19 vaccinations will help guide radiologists and oncologists in their management of patients, both present oncologic patients, and patients with concerns over their newly presenting lymphadenopathy. A systematic literature search was performed using several databases to identify relevant studies that reported lymphadenopathy post-COVID-19 vaccination. Our results revealed that several cases have been detected in patients undergoing follow-up fluorodeoxyglucose (FDG)-positron emission tomography-computerized tomography scans where lymph nodes ipsilateral to the vaccine injection site show increased uptake of FDG. Thus, knowledge of the incidence of lymphadenopathy may help avoid unnecessary biopsies, interventions, and changes in management for patients, especially oncologic patients who are at risk for malignancies.

A pilot study of the effects of faculty status for medical librarians in the United States.

OBJECTIVES: Within many institutions, there are debates over whether medical librarians should be classified as faculty or professional staff, a distinction that may have considerable effect on the perception of librarians within their local institutions. This study is a pilot exploration of how faculty status may affect the professional experiences of academic medical librarians within their local institutions. METHODS: Surveys were sent to 209 medical librarians listed as having some instructional function at Liaison Committee on Medical Education (LCME) accredited medical institutions in the United States. Survey responses were captured using Qualtrics survey tool and analyzed for frequencies and associations using SPSS version 27. RESULTS: Sixty-four medical librarians at academic medical institutions completed the survey developed for this study. Of the respondents, 60.9% indicated that librarians at their institution have faculty status, while 71.9% believe that librarians at their institution should have faculty status. Ninety percent of librarians with faculty status reported that they are expected to generate scholarly materials, compared to 28% of those without faculty status. CONCLUSIONS: Many medical libraries offer faculty status to librarians. While many medical librarians are active in instruction, research, and other activities normally associated with faculty status, it is not clear if faculty status impacts how librarians are perceived by other health care workers within their institutions.

Information-Seeking Behaviors of Medical Faculty at a Qatar Academic Medical Institution.

Medical faculty are among the most important user groups at any academic medical library. Knowing how medical faculty identify, access, and use information is important for collection development and instruction. This study found that medical faculty at an institution in Qatar identified information access and use as vital in their professional duties. However, they also noted limitations that warrant attention by the library to better serve this user group. Further, the results of this study were compared to a similar study of medical faculty in the United States, with noted similarities and differences in their access and use of information.

Examining aptitude and barriers to evidence-based medicine among trainees at an ACGME-I accredited program.

BACKGROUND: The aims of Evidence-Based medicine (EBM) are to promote critical thinking and produces better patients' outcome (Profetto-McGrath J, J Prof Nurs Off J Am Assoc Coll Nurs 21:364-371, 2005). Accreditation Council for Graduate Medical Education (ACGME) competencies require trainees to locate, appraise and apply clinical evidence to patients' care. Despite the emphasis that ACGME place on EBM, few organizations provide adequate training in EBM. This is even more critical in regions where medical trainees matriculate from diverse backgrounds of undergraduate medical education, where EBM may not be emphasized nor taught at all. EBM practice has a history of research in the West, however, EBM has not been widely studied in the Middle East. METHODS: Clinicians and trainees at Hamad Medical Corporation (HMC) matriculate from many countries in the Middle East and North Africa (MENA) and Asia. Because trainees in Graduate Medical Education (GME) come to HMC from a variety of geographic backgrounds, it is assumed that they also have a variety of experiences and aptitudes in EBM. To assess trainees EBM attitudes and knowledge in the internal medicine department at HMC in Doha, Qatar, the authors surveyed residents and fellows using a two-part survey. The first part was adapted from the evidence-based practice inventory by Kaper to assess trainees' attitudes and perceptions of EBM. Trainees were also asked to complete the Assessing Competency in Evidence Based Medicine (ACE) tool to evaluate their aptitude in different elements of EBM. The results from the two parts were analyzed. RESULTS: The average score on the ACE tool among the participants was 8.9 (±1.6). Most participants rated themselves as beginners or intermediate in their EBM capabilities. Higher ACE scores were observed from participants with educational background from South Asia, and among those with more favorable attitudes towards EBM. There was no clear pattern that early incorporation of EBM into practice will result in better ACE score. Participants also reported reasonable abilities in EBM tasks and a favorable work atmosphere for EBM implementation. Lack of knowledge, resources, and time were the most reported barriers to utilizing EBM. CONCLUSIONS: While it is clear that participants are enthusiastic about EBM and see it as a useful method for clinical decision making, their aptitude in EBM is not optimal and there are gaps and barriers for them to practice.

Using Time-Driven Activity-Based Costing to Implement Change.

Academic medical libraries have responded to changes in technology, evolving professional roles, reduced budgets, and declining traditional services. Libraries that have taken a proactive role to change have seen their librarians emerge as collaborators and partners with faculty and researchers, while para-professional staff is increasingly overseeing traditional services. This article addresses shifting staff and schedules at a single-service-point information desk by using time-driven activity-based costing to determine the utilization of resources available to provide traditional library services. Opening hours and schedules were changed, allowing librarians to focus on patrons' information needs in their own environment.

Impact of tobacco smoking on disease-specific outcomes in common neurological disorders: A scoping review.

Although the association of smoking with the risk of incident neurological disorders is well established, less is known about the impact of smoking and smoking cessation on outcomes of these conditions. The objective of this scoping review was to synthesize what is known about the impact of smoking and smoking cessation on disease-specific outcomes for seven common neurological disorders. We included 67 studies on the association of smoking and smoking cessation on disease-specific outcomes. For multiple sclerosis, smoking was associated with greater clinical and radiological disease progression, relapses, risk for disease-related death, cognitive decline, and mood symptoms, in addition to reduced treatment effectiveness. For stroke and transient ischemic attack, smoking was associated with greater rates of stroke recurrence, post-stroke cardiovascular outcomes, post-stroke mortality, post-stroke cognitive impairment, and functional impairment. In patients with cognitive impairment and dementia, smoking was associated with faster cognitive decline, and smoking was also associated with greater cognitive decline in Parkinson's disease, but not motor symptom worsening. Patients with amyotrophic lateral sclerosis who smoked faced increased mortality. Last, in patients with cluster headache, smoking was associated with more frequent and longer cluster attack periods. Conversely, for multiple sclerosis and stroke, smoking cessation was associated with improved disease-specific outcomes. In summary, whereas smoking is detrimentally associated with disease-specific outcomes in common neurological conditions, there is growing evidence that smoking cessation may improve outcomes. Effective smoking cessation interventions should be leveraged in the management of common neurological disorders to improve patient outcomes.

Shared decision making with black patients: A scoping review.

OBJECTIVE: The purpose of this review is to explore the breadth of research conducted on SDM in the care of Black patients. METHODS: We conducted a scoping review following the methodological framework outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. We searched articles related to original research on SDM in the care of Black patients in October 2022 using PubMed, Embase, and Google Scholar databases. Articles of all study designs (quantitative and qualitative), published or translated into English, were included. A standardized data extraction form and thematic analysis were used to facilitate data extraction by two independent reviewers. RESULTS: After removal of duplicates and screening, 30 articles were included in the final analysis. Black patients and clinician were found to not share the same understanding of SDM, and patients highly valued SDM in their care. Interventions to improve SDM yielded mixed results to enhance intent, participation in SDM, as well as health outcomes. Decision aids were the most effective form of intervention to enhance SDM. The most common barrier to SDM was patient-clinician communication, and was exacerbated by racial discordance, clinician mistrust, past experiences, and paternalistic clinician-patient dynamics. CONCLUSIONS: SDM has the potential to improve health outcomes in Black patients when implemented contextually within Black patients' experiences and concerns. Significant barriers such as clinician mistrust exist, and the overall perception in the Black community is that SDM does not occur sufficiently. Barriers to SDM seem to be most pronounced when there is patient-clinician racial discordance. Several interventions aimed at improving SDM with Black patients have shown mixed results. Future studies should evaluate larger-scale interventions with longer follow-up. Practice implications Shared decision making (SDM) has been proposed as a useful tool for improving quality and equity in Black patients' care. However, Black patients experience lower rates of SDM compared to other populations. SDM has the potential to improve health outcomes in Black patients when implemented contextually within Black patients' experiences and concerns.
