Background: This bibliometric analysis examines the top 50 most-cited articles on COVID-19 complications, offering insights into the multifaceted impact of the virus. Since its emergence in Wuhan in December 2019, COVID-19 has evolved into a global health crisis, with over 770 million confirmed cases and 6.9 million deaths as of September 2023. Initially recognized as a respiratory illness causing pneumonia and ARDS, its diverse complications extend to cardiovascular, gastrointestinal, renal, hematological, neurological, endocrinological, ophthalmological, hepatobiliary, and dermatological systems. Methods: Identifying the top 50 articles from a pool of 5940 in Scopus, the analysis spans November 2019 to July 2021, employing terms related to COVID-19 and complications. Rigorous review criteria excluded non-relevant studies, basic science research, and animal models. The authors independently reviewed articles, considering factors like title, citations, publication year, journal, impact factor, authors, study details, and patient demographics. Results: The focus is primarily on 2020 publications (96%), with all articles being open access. Leading journals include The Lancet, NEJM, and JAMA, with prominent contributions from Internal Medicine (46.9%) and Pulmonary Medicine (14.5%). China played a major role (34.9%), followed by France and Belgium. Clinical features were the primary study topic (68%), often utilizing retrospective designs (24%). Among 22,477 patients analyzed, 54.8% were male, with the most common age group being 26-65 years (63.2%). Complications of COVID-19 affected 13.9% of patients, with a recovery rate of 57.8%. Conclusion: Analyzing these top-cited articles offers clinicians and researchers a comprehensive, timely understanding of influential COVID-19 literature. This approach uncovers attributes contributing to high citations and provides authors with valuable insights for crafting impactful research. As a strategic tool, this analysis facilitates staying updated and making meaningful contributions to the dynamic field of COVID-19 research.

A Case of Balo Concentric Sclerosis: A Multiple Sclerosis Mimic.

Balo Concentric Sclerosis (BCS) is a rare neurological demyelinating disorder similar to Multiple Sclerosis. Both present with progressive neurological debility but differences on brain imaging help with distinction. The lack of prevalence and general diagnostic information about BCS makes it an underdiagnosed disease which can sometimes delay treatment. This case of BCS was initially treated as an infectious brain mass, leading to unnecessary interventions. Early recognition and differentiation from other neurological conditions are crucial for appropriate management and prognosis. We hope that by presenting this case, we can aid in creating diagnostic criteria and promote awareness of this chronic debilitating disease.

A Case With Twists and Turns: A Report of Vertebrobasilar Dolichoectasia.

Vertebrobasilar dolichoectasia (VBD) is a rare anatomical abnormality of the vertebral artery system, defined as irregular expansion, elongation, and tortuosity of vertebral arteries. Anomalies of the vertebrobasilar artery can have a wide variety of clinical presentations, ranging from simple headaches to debilitating strokes. We present the case of an atypical presentation of VBD which mimicked trigeminal neuralgia by compressing the trigeminal nerve. There are currently no guidelines concerning the management of VBD, nor is there evidence of a definitive cure. This case invoked discussions among the medical team as to whether management should be medically or surgically focused, as well as long-term outcomes for patients with VBD. The superiority of medical versus surgical treatment of this issue is still a debated topic. This patient trialed medical management with dexamethasone and carbamazepine with no improvement in symptoms. He then underwent surgical gamma knife treatment but even this invasive measure was unsuccessful at relieving his symptoms. We hope that by presenting this case, we can display how the therapies available for VBD are limited and often unsuccessful in relieving the disease burden in patients with VBD.

A Difficult Differential Diagnosis in New Neck Masses: Retropharyngeal Abscess or Malignancy?

Retropharyngeal abscesses (RPAs) are rare in the adult population and rarer without an inciting event or comorbidity such as recent oral surgery, neck infection, or pharyngeal trauma. The definitive treatment is incision and drainage of the abscess. Clinical researchers have recently questioned whether invasive surgical intervention is necessary and posed the question of what role antibiotics play in management. Sequelae of RPAs are severe and include rupture of the abscess, erosion of the carotid artery, thrombophlebitis, and most seriously, airway compromise. We present a case where an atypical presentation of an RPA caused a disagreement among specialists, and the debate of whether the described case represented an abscess or malignancy caused a delay in diagnosis and treatment for the patient. Only after invasive and emergent surgical intervention was a final diagnosis able to be made. This case demonstrates the need for more research and official guidance on the management of new neck masses to hasten diagnosis and prevent devastating outcomes.

A Case of Secondary Autoimmune Hemolytic Anemia Successfully Treated With Rituximab.

Secondary cold agglutinin autoimmune hemolytic anemia (AIHA) occurs most commonly due to infectious causes like Mycoplasma pneumonia and, more rarely, Epstein-Barr virus(EBV). Here we present a case of a 69-year-old female presenting with generalized weakness, who was found to have cold agglutinin hemolytic anemia. She unfortunately experienced some of the most severe complications of the disease including encephalopathy, hypoxia, and dry necrosis of peripheral extremities. Further investigation revealed an EBV infection, the rarest infectious cause of cold AIHA. She was started on steroids, the mainstay of treatment, but continued to worsen over the course of her extensive stay in the intensive care unit (ICU). Given the severity of the disease, the decision was made to use plasmapheresis and rituximab, the monoclonal antibody directed against CD20, as an experimental therapy. After adjunctive therapy was initiated, the patient began to clinically improve and ultimately made a full recovery. Rituximab is historically only effective in primary cold AIHA, but it appeared to elicit significant clinical improvement with our use in secondary cold AIHA. While there have been a handful of studies demonstrating its successful use in secondary cold AIHA, we propose that this medication be further studied to prevent the significant morbidity and mortality associated with the disease.

Acyclovir as a Novel Treatment for Severe Chronic Active Epstein-Barr Virus.

Epstein-Barr virus (EBV) is a widely infectious pathogen affecting most of the global population at some point in their life. While, typically, primary infections are subclinical, chronic persistence of the virus due to T-cell proliferation can cause severe complications. Acute hepatitis due to chronic active EBV (CAEBV) has rarely been documented. This case details a previously healthy 81-year-old woman who presented with complaints of diffuse abdominal pain, nausea, and vomiting. Her diagnostic workup demonstrated an EBV infection with worsening thrombocytopenia, transaminitis, and hepatocellular liver injury with acute ascites. Her hospitalization was resistant to the traditional supportive treatment of EBV, requiring intensive care management and unorthodox therapy. Although antivirals have demonstrated limited utility in the treatment of CAEBV, the severity of her illness and refractory hospital course necessitated the use of acyclovir. She made a complete recovery with no deficits. The case demonstrates the presentation of acute hepatitis and ascites as a result of CAEBV, the clinical sequelae, and acyclovir as a potential new treatment option.

Exploring differences in and factors influencing self-efficacy for competence in interprofessional collaborative practice among health professions students.

The value of health care delivered via effective interprofessional teams has created an imperative for interprofessional education (IPE) and interprofessional collaborative practice (ICP). To inform IPE strategies, we investigated differences in perceived self-efficacy (SE) for competence in ICP among health professions students. The study data were collected between 2015 and 2019 from students from 13 different health professions programmes (N = 3,497) before an annual institutional interprofessional programme. Students completed the IPECC-SET-27, a validated instrument evaluating perceived SE for competence in ICP, and rated their 1) amount of previous contact with, and 2) perceived understanding of, the role of different health professions. Students in different health professions education programmes were compared using parametric statistics. Regression analyses explored factors influencing SE for competence in ICP. Findings revealed significant differences in perceived SE for competence in ICP between programmes (p < .05). Specifically, health information management/health informatics, dentistry, medicine, and nursing students expressed relatively higher SE, whereas physical therapy and occupational therapy students expressed relatively lower SE. Perceived understanding of the role of health professions (p < .01) and gender (p < .01) contributed significantly to predicting perceived SE for competence in ICP, while the amount of previous contact with other health professions did not (p = .42). The findings highlight the value of designing IPE with consideration of specific learner needs.

Comparison of Two Clinical Laboratory Assays for Measuring Serum Adalimumab and Antibodies to Adalimumab.

BACKGROUND: Adalimumab is a fully human monoclonal antibody developed against tumor necrosis factor (TNF), used for the treatment of autoimmune and chronic inflammatory diseases. Immunogenicity to this drug may lead to therapeutic failure. Various laboratory assays are used for measuring serum adalimumab and anti-drug antibodies (ADA) to adalimumab, for therapeutic monitoring and evaluation of clinical non-responsiveness. This study compared the performance of 2 clinical assays used by different reference laboratories. METHODS: In total, 120 residual clinical samples were tested at both laboratories. A sandwich ELISA for adalimumab detecting free drug and a bridging ELISA capable of detecting both free and bound ADA were performed at the Mayo Clinic. A functional cell-based reporter gene assay (RGA) was used at ARUP Laboratories for measuring bioactive serum drug concentrations, and neutralizing ADA. RESULTS: Seventy-eight samples had measurable concentrations of adalimumab by both methods and yielded a correlation coefficient r = 0.93, slope = 0.886, and intercept = 0.950. Overall agreement of 92.5% was observed between the assays, with most discrepant drug results being attributed to a higher positivity rate with ELISA (8/9). One outlier positive with RGA and negative with ELISA was confirmed by LC-MS/MS to be attributed to infliximab. Overall agreement of 79.2% was observed between the ADA assays. Differences in ADA results may be due to the bridging ELISA detecting total ADA (free, drug-bound, neutralizing, and non-neutralizing), while RGA detects free, neutralizing ADA only. CONCLUSIONS: Although the assays are fundamentally different, the results show significant concordance between the clinically validated tests performed in different laboratories.

Neurological Manifestations of Coronavirus Disease 2019 and Mpox in Pediatric Patients and Their Management: A State-of-the-Art Systematic Review.

BACKGROUND: There is an increasing number of cases being reported of neurological manifestations of Coronavirus disease 2019 (COVID-19) infection and Monkeypox (Mpox), both during the course of the infection and as a presenting symptom. We aim to review the neurological manifestations of COVID-19 and monkeypox in pediatric patients and their management. METHODS: We conducted a systematic review that included cohort studies and case series or reports involving a pediatric population of patients with a confirmed COVID-19 or Mpox infection and their neurological manifestations. We searched the following electronic databases: PubMed, EMBASE, and Scopus. RESULTS: From 1136 articles identified, 127 studies were included. Headache, stroke, Guillain-Barré syndrome, seizure, nerve palsies, and multisystem inflammatory syndrome in children were the most common neurological symptoms caused by COVID-19, whereas encephalitis was commonly seen in patients with Mpox. Rare neurological manifestations of COVID-19 included cerebral venous sinus thrombosis, plexopathies, demyelinating disorders, encephalitis, etc., and rare neurological manifestations of Mpox included headache. CONCLUSIONS: Our review highlights the importance of investigating possible neurological manifestations and closely monitoring these patients to develop a better understanding of the treatment strategies that can be adopted.

Profile of Secondary Bacterial and Fungal Infections in Hospitalized COVID-19 Patients in a Tertiary Care Centre.

Introduction: SARS CoV-2, a novel corona virus, has emerged in December 2019. The COVID-19 associated mortality is documented in elderly with co morbidities. To have better insight on this issue, the secondary bacterial infections with multi-drug-resistant bacteria in COVID-19 patients need to be studied to evaluate the impact of these infections on the outcome. Aim and objectives: To determine the proportion of secondary infections in COVID-19 patients. To study the spectrum of pathogens and antibiogram of the bacteria isolated from secondary infections in such patients. To evaluate the co-existing co-morbidities, treatment and outcome in these patients. Methodology: The retrospective study was conducted in Departments of Medicine and Microbiology, KMC hospitals Attavara and Ambedkar circle, Mangaluru, including all the hospitalized microbiologically confirmed cases of SARS CoV-2 infection. Details pertaining to the study population were collected using a structured proforma. Descriptive data were entered in the form of mean, median and proportions. The categorical values were analyzed using Chi square test. Values of p < 0.05 were considered as statistically significant. Results: Two hundred COVID-19 hospitalized patients were included.28 out of 200 patients (14%) studied developed secondary infections. The types of secondary infections were Respiratory infections (50%), blood stream infections (17%), UTI (14%), Rhinocerebral Zygomycosis (17%). The predominant organisms were Klebsiella pneumoniae (44%), Zygomycetes (17%). The rates of antibiotic resistance in Gram negative bacilli were 33% to Cefuroxime,25% to aminoglycosides and fluoroquinolones and 16% to carbapenems. The mortality of 42.8% was observed in patients with secondary infections. Conclusion: Close monitoring and follow up especially in high-risk group of severe COVID 19 patients is crucial for better management and outcome.

Estimating staffing requirements using workload indicators of staffing need at Braun District Hospital in Morobe Province, Papua New Guinea.

BACKGROUND: Papua New Guinea has seen some improvements in health indicators over the past years, but the pace of improvements is not as robust as expected. The Health Services Plan for Braun District Hospital redevelopment identified the importance of reflecting the hospital's role in the broader health system, particularly in upgrading the services to service a bigger population. In August 2020, the hospital was upgraded from a health centre-level 3 to a district hospital level 4. The need for assessing human resources for health requirements for this level of care was thus necessary. METHODS: The National Department of Health approved the use of the workload indicators of staffing need as the best tool to support in estimating staff requirements for the newly upgraded hospital. The focus was on clinical and non-clinical staff. Using already developed workload components and activity standards by the expert working groups for level 4 facilities, we visited the facility and collected data through interviews with the Lutheran Health Services representative, hospital management and staff. The technical task force reviewed daily registers, monthly reports and the data in the electronic national health information systems. The information collected was analysed using the workload indicators of staffing need software and interpreted. RESULTS: There were staffing shortages among the clinical staff like the medical officers, nursing officers, health extension officers, pharmacists, radiology staff unit and in the laboratory staff. Shortages among the non-clinical staff were recorded by the cashiers, security officers, drivers and boat skippers. The results showed that the facility lacks a medical laboratory technologist, pharmacists and a medical imaging technologist. The community health workers in this facility are utilized in all the areas where shortages are registered to multitask. CONCLUSION: The results from this WISN study provide evidence for basing staffing decisions on. The WISN results from Braun District Hospital show that the facility requires a total of 33 inpatient nurses against the existing 21 inpatient nurses thus giving a staff gap of - 12 and a WISN ratio of 0.67. It is thus recommended that the hospital management prioritizes recruitment of nurses or if no resources, reassign one of the outpatient nurses to alleviate the pressure among the inpatient nurses or the extra theatre nurses to offer some services in the inpatient wards. WISN results can help managers make decisions such as change of health facility status from a health centre to a district hospital.

Corneal injury secondary to silver nitrate stick mistaken for cotton bud.

PURPOSE: This case report highlights the potential for error when removing corneal foreign bodies in a shared speciality area in Accident and Emergency (A&E). OBSERVATIONS: This case presents the accidental use of a silver nitrate stick rather than a cotton bud to remove a corneal foreign body. This resulted in a corneal injury requiring ophthalmological referral and management with topical antibiotics, topical steroids and lubricants. CONCLUSIONS: Mistaking a silver nitrate stick for a cotton bud is a tangible risk in a busy A&E and can result in significant corneal injury. Clinicians and departments can greatly reduce this risk by having separate and secure storage of similar consumables, as well as keeping consumables in original packaging and discarding of the remainder after a pack has been opened. Minimizing the risk for error will better safeguard and improve patient safety.

Evaluation of a Mental and Behavioral Health Patient Room Mockup at a VA Facility.

OBJECTIVE: The primary goal of this research was to evaluate a physical full-scale, high-fidelity mockup of a mental and behavioral health (MBH) inpatient room and bathroom. BACKGROUND: There is minimal research on design for MBH and no published research using mockups to evaluate a MBH design proposal. To address this gap, an interdisciplinary team developed an ideal Patient-Centered MBH Patient Room, which was built as a mockup at a Veterans Administration (VA) facility and evaluated by patients and staff in situ. METHOD: The mock-up was evaluated using a structured mixed methods process that incorporates feedback using Feedback Forms and facilitated Listening Sessions. Our two primary hypotheses were that the design, as represented by the mock-up, would be positively evaluated and that there would be a difference between staff and patient perceptions, with patients rating the design higher than staff. RESULTS: Quantitative analysis confirmed our hypotheses, revealing an overall positive response, with a difference between patients and staff. Contrary to hypothesis, staff consistently rated the design higher than patients. Qualitative analysis found mixed reception of the design and three primary themes: safety, homeyness/deinstitutionalization, and positive distraction/nature. CONCLUSIONS: Physical mock-ups may be an effective tool for evaluation of a proposed design; however, staff perceptions of the environment may differ from those of patients. One drawback of using a physical high-fidelity mock-up is the expectation that the mock-up perfectly represents the proposed design. With this project, even small unfinished details were distracting to the participants and may have negatively affected the evaluation.

Impacts of small vestibular schwannoma on community ambulation, postural, and ocular control.

OBJECTIVES/HYPOTHESIS: To investigate balance, community mobility, gaze instability, and dizziness handicap and assess falls risk in people who are conservatively managed with small vestibular schwannoma (VS). STUDY DESIGN: Cross-sectional study with controls. METHODS: The study involved 18 people (mean age 58.7 ± 12.2 years) diagnosed with VS (<12 mm) and 22 age-matched controls (mean age 56.9 ± 8.0 years). Measures included standing on firm and foam surfaces with feet apart, then together with eyes open and closed, Timed Up and Go (TUG) test and dual TUG test, Dynamic Gait Index, 6-Minute Walk Test, Halmagyi Impulse Test, Dynamic Visual Acuity Test, and the Dizziness Handicap Inventory. RESULTS: The clinical group failed more trials standing feet together on foam with eyes closed (P < .05); had inferior mobility and walked more slowly with divided attention (P < .05); had more difficulty walking with head movement, negotiating obstacles, and using stairs (P < .01); and walked shorter distances (P < .001) than controls. Reduced gaze stability (P < .01) and higher total (P = .007) and subcategory dizziness handicap scores (P < .05) were revealed compared to age-matched controls. CONCLUSIONS: Although outcomes for the clinical group are inferior to the control group across all measures and the dizziness impact is higher, the results fall in the low-risk category for falls. Preliminary data (level 4 evidence) support using a suite of clinical measures to monitor people with VS during conservative management. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:1147-1152, 2017.

Bacterial Composition at the Implant-Abutment Connection under Loading in vivo.

PURPOSE: Platform-switched implants have been demonstrated to prevent bone loss after loading. The present study evaluated bacterial composition of sites from implant-abutment connections of immediately loaded implants, which were placed in the anterior mandible. Ten patients participated in this study. MATERIALS AND METHODS: A and B implant systems with two different prosthetic connections (Morse tapered vs internal polygonal butt-joint connections, respectively) were placed and loaded for 2 years. The abutments were removed (AB sample) after careful decontamination. Bacterial sampling of the abutments, inner part of the implants (before/visit 1 and after rinsing with chlorhexidine [CHX]/visit 2), and after new abutment connection and loading for 1 additional month, a new sampling (visit 3) was taken to compare the bacteria composition in association with the two connections. Bacterial profiles of samples were determined by using the human oral microbe identification microarray. RESULTS: A total of 240 samples were analyzed taken at different time intervals. Nonparametric statistical analysis (Wilcoxon Rank sum) with uncorrected alpha (p < .05) and after corrections (Benjamini-Hochberg) found no statistical significance between the two connections. No significant changes in the overall microbial profiles were detected at the different time intervals. However, there were trends toward presence of periodontitis-associated species at the B implants in all samples (AB, visit 1, even after CHX irrigation) and after decontamination, abutment replacement, and 1-month loading period. CONCLUSIONS: CHX irrigation does not seem to have any effect on decontamination of connections. As shown previously, there is significantly more bone loss around B implants compared with A implants. Although there was no statistical difference in the microbial profiles, there was indeed a trend for the presence of typical periodontal pathogens associated with the internal polygonal butt-joint connection. A possible scenario is that this connection tends to harbor the pathogens that may be involved in subsequent bone loss.

Characterization of a human powered nebulizer compressor for resource poor settings.

BACKGROUND: Respiratory disease accounts for three of the ten leading causes of death worldwide. Many of these diseases can be treated and diagnosed using a nebulizer. Nebulizers can also be used to safely and efficiently deliver vaccines. Unfortunately, commercially available nebulizers are not designed for use in regions of the world where lung disease is most prevalent: they are electricity-dependent, cost-prohibitive, and not built to be reliable in harsh operating conditions or under frequent use.To overcome these limitations, the Human Powered Nebulizer compressor (HPN) was developed. The HPN does not require electricity; instead airflow is generated manually through a hand-crank or bicycle-style pedal system. A health care worker or other trained individual operates the device while the patient receives treatment.This study demonstrates functional specifications of the HPN in comparison with a standard commercially available electric jet nebulizer compressor, the DeVilbiss Pulmo-Aide 5650D (Pulmo-Aide). METHODS: Pressure and flow characteristics were measured with a rotameter and pressure transducer, respectively. Volume nebulized by each compressor was determined by mass, and particle size distribution was determined via laser diffraction. The Hudson RCI Micro Mist nebulizer mouthpiece was used with both compressors. RESULTS: The pressure and flow generated by the HPN and Pulmo-Aide were: 15.17 psi and 10.5 L/min; and 14.65 psi and 11.2 L/min, respectively. The volume of liquid delivered by each was equivalent, 1.097 ± 0.107 mL (mean ± s.e.m., n = 13) for the HPN and 1.092 ± 0.116 mL for the Pulmo-Aide. The average particle size was also equivalent, 5.38 ± 0.040 micrometers (mean ± s.e.m., n = 7) and 5.40 ± 0.025 micrometers, respectively. CONCLUSIONS: Based on these characteristics, the HPN's performance is equivalent to a popular commercially available electric nebulizer compressor. The findings presented in this paper, combined with the results of two published clinical studies, suggest that the HPN could serve as an important diagnostic and therapeutic tool in the fight against global respiratory health challenges including: tuberculosis, chronic obstructive pulmonary disease, asthma, and lower respiratory infections.

The longitudinal prediction of alcohol consumption-related harms among young adults.

This study explores the longitudinal pathways by which risk and protective factors influence the development of alcohol-related harms in a representative community sample of 941 young adults (19-20 years) from Victoria, Australia, focusing on the role of concurrent risky drinking. Impulsivity at 15-16 years, alcohol-related harms at 15-16 years and 17-18 years, frequency of intoxication at 17-18 years, and antisocial behavior, friends' drinking and living arrangements at 19-20 years were directly related to alcohol-related harms, as well as indirectly related to harms through increased risky drinking. Paternal drinking at 17-18 years was directly related to alcohol-related harms. Friends' drinking at 19-20 years and alcohol-related harms at age 17-18 interacted with risky drinking to increase the likelihood of alcohol-related harms. Implications for intervention efforts are discussed.

Nursing assistant walking report at change of shift.

Change of shift is a time when nurses and nursing assistants are less visible to their patients. By instituting a walking report by nursing assistants, there was an improvement in patient satisfaction related to call light responsiveness, reduction in falls, decrease in call light use, and improved call light response time by the staff. Pressure ulcer rates did not change.
