Authors: Musa Hassan H , Musa Taha H , Musa Ibrahim H , Musa Idriss H 
Published: April 2021

Abstract

Background
Mycetoma is a neglected tropical disease that attracts little attention in regard to research and publications and hence this study was undertaken to determine the trends and global scientific research output in mycetoma-related fields.

Methods
Mycetoma data were retrieved from the Web of Science (WoS) and Scopus databases. The MeSH Browser was used to extract relevant keywords. Biblioshiny software (R-studio cloud), VOSviewer v. 1.6.6 and SPSS software were used for data management.

Results
Research trends on mycetoma increased globally from 1999 to 2020. The results were 404 documents (4444 citations) in WoS and 513 documents (5709 citations) in Scopus, and the average number of citations per article was 11 in WoS and 11.13 in Scopus. There was a significant association between the total number of citations and the total citations per year in both WoS (r=0.833, p&lt;0.0001) and Scopus (r=0.926, p&lt;0.0001). Sudan, India, the Netherlands and Mexico were the top-ranking productive countries for mycetoma publications in WoS, while India, the USA and Mexico were the top-ranking countries in Scopus. Articles on mycetoma were mainly published in PLoS Neglected Tropical Diseases, the International Journal of Dermatology and the Journal of Clinical Microbiology. A. H. Fahal from the Mycetoma Research Centre, University of Khartoum, Sudan, had the highest number of citations in mycetoma research during 1999–2020, followed by W. W. J. van de Sande from the Erasmus Medical Centre, University of Rotterdam, the Netherlands, during 2003–2020.

Conclusion
The analysis provides insight into a global overview of Mycetoma research. In addition, the analysis holds a better understanding of the development trends that have emerged in Mycetoma over the past 21 years, which can also offer a scientific reference for future research.
Nasal cannula or high-flow oxygen for patients with COPD in acute respiratory distress?
Authors: Tasota Frederick J. , Kress Terri L. , Conlin Tiffany L. , Scarmack Natalie M. 
Published: April 2021

Abstract:
There may be some confusion regarding the use of supplemental oxygen in patients with chronic obstructive pulmonary disease (COPD) who are experiencing acute respiratory distress. This article addresses a common nursing misconception regarding the use of high-flow oxygen administration via non-rebreather masks instead of low-flow oxygen administration via nasal cannulas in patients with COPD who are in acute respiratory distress, an issue that was investigated in a simulation education exercise and survey of the nursing staff at the authors' facility.
What Influences Outcomes From Inpatient Multidisciplinary Pain Management Programs?
Authors: Lewis Gwyn N. , Bean Debbie J. 
Published: April 2021

Objectives:Although inpatient multidisciplinary pain management programs (PMPs) are effective for chronic pain, not all patients benefit equally and there is limited evidence regarding predictors of outcome. This meta-analysis aimed to identify patient or program characteristics associated with outcomes from inpatient PMPs, and to examine the time course of effects following discharge.Materials and Methods:Medline, EBSCO, and Scopus were searched to identify articles reporting outcomes from inpatient multidisciplinary PMPs. Information was extracted on study design, participant and program characteristics, and outcomes. Effect sizes were computed for pain, physical function, depression, anxiety, and mental health outcomes. Study-level predictors of outcome were investigated with moderator analyses and meta-regression. A risk of bias assessment and sensitivity analyses were conducted and the GRADE criteria for prognostic studies were applied to assess confidence in findings.Results:In all, 85 studies (111 cohorts; 15,255 participants) were included. Three quarters of studies demonstrated low risk of bias. Larger effect sizes (for at least 1 outcome measure) occurred in studies where participants had more severe pain (greater intensity/longer duration), participants with alcohol or drug problems were not excluded, samples comprised mixed pain conditions, and programs included a cognitive component and/or a passive therapy component. Effect sizes for pain and physical function were maintained at follow-up, but effect sizes for depression and anxiety declined over time.Discussion:Inpatient multidisciplinary PMPs may be well suited to patients with severe or long-lasting pain. Programs should adopt broad patient inclusion criteria, and outcomes were similar for programs based on cognitive-behavioral versus mindfulness/acceptance-based therapies.

Published: April 2021

Background:
Evidence of nonauditory health effects of road traffic noise exposure is growing. This prospective cohort study aimed to estimate the association between long-term exposure to road traffic noise above a threshold and incident myocardial infarction (MI) in Denmark.

Methods:
In the Danish Nurse Cohort study, we used data of 22,378 women, at recruitment in 1993 and 1999, who reported information on MI risk factors. The participants’ first hospital contact or out-of-hospital death due to MI were followed-up until 2014. We investigated a relationship between residential exposures to road traffic noise levels (Lden) up to 23 years and incident MI (overall, nonfatal, and fatal) using time-varying Cox regression models adjusting for potential confounders and air pollutants. We estimated thresholds of road traffic noise (53, 56, and 58 dB) associated with incident MI in a piece-wise linear regression model.

Results:
Of the 22,378 participants, 633 developed MI, 502 of which were nonfatal. We observed a non-linear relationship between the 23-year running mean of Lden and incident MI with a threshold level of 56 dB, above which hazard ratios (95% confidence intervals) were 1.30 (0.97, 1.75) for overall and 1.46 (1.05, 2.03) for nonfatal MI per 10 dB. The association with nonfatal MI attenuated slightly to 1.34 (0.95, 1.90) after adjustment for fine particles.

Conclusions:
We found that long-term exposure to road traffic noise above 56 dB may increase the risk of MI. The study findings suggest that road traffic noise above 56 dB may need regulation in addition to the regulation of ambient pollutants.
Autophagy Induced by a Novel Triazol Derivative Promotes Angiogenesis Through Decreasing Interferon-Inducible Protein 10 Level in Vascular Endothelial Cells

Published: April 2021

Abstract:
Autophagy plays an important role in angiogenesis, whereas the mechanisms of vascular endothelial cell (VEC) autophagy associated with angiogenesis remain unclear. In this study, we identified a novel triazol derivative (JL025) that significantly promoted angiogenesis both in vitro and in vivo. Moreover, JL025 had no effects on cell proliferation but dramatically increased the autophagy level of VEC. The suppression of autophagy inhibited JL025-induced angiogenesis in vitro and in vivo, suggesting that JL025-induced angiogenesis was dependent on the enhanced autophagy. Mechanistic studies indicated that JL025-induced VEC autophagy was related to the Protein Kinase B/mTOR signaling pathway. Meanwhile, JL025 decreased the antiangiogenic chemokine interferon-inducible protein 10 (IP10) protein level in human VECs. Importantly, the suppression of autophagy inhibited JL025-induced decrease of IP10 protein level, indicating that autophagy mediated the degradation of IP10. Taken together, our findings provide new insights into the relationship of VEC autophagy with angiogenesis, and JL025 may have a therapeutic potential in related diseases.
Evaluation of the Mechanisms Underlying Amino Acid and Microbiota Interactions in Intestinal Infections Using Germ-Free Animals

Published: April 2021

Abstract
Intestinal infectious diseases refer to the inflammatory changes in the intestinal tract caused by pathogens (including bacteria, viruses, fungi, protozoa, or parasites) or their toxic products. A large number of microorganisms colonize the intestinal tract of healthy people, which together with the intestinal epithelium constitute the biological barrier of the intestinal tract to resist infectious diseases. As an “invisible organ,” the intestinal flora is closely related to human nutrition metabolism and intestinal infections. A variety of intestinal flora participates in the nutritional metabolism of amino acids, and the small molecular substances produced by the amino acid metabolism through the intestinal flora can enhance intestinal immunity and resist bacterial infections. In turn, amino acids can also regulate the composition of the intestinal flora, maintain the steady-state of the intestinal flora, protect the intestinal barrier, and inhibit colonization by pathogenic bacteria. As a model animal with a clear microbial background, germ-free (GF) animals can clarify the mechanisms of interactions between intestinal microbes and amino acid metabolism in intestinal infections by combining genetic engineering technology and multi-omics studies. This article reviews related researches on the involvement of intestinal microbes in host amino acid metabolism and resistance to intestinal infections and discusses the advantages of GF animal models for studying the underlying mechanisms. The GF animal model is helpful to further study the intervention effects of amino acid metabolism of targeted intestinal flora on intestinal infections.

Published: April 2021

Objective
This study aimed to investigate the prevalence of sexually transmitted infections (STIs) and colonizing bacteria in relation to urogenital symptoms.

Materials and Methods
In this cross-sectional study, patients visiting the STI clinic at Umeå University Hospital were asked for symptoms and condom use. Samples from 759 patients (465 male and 294 female) were analyzed for 4 STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Mycoplasma genitalium) and 3 colonizing bacteria (Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum).

Results

Chlamydia trachomatis prevalence was 11% among women and 9.5% among men. Neisseria gonorrhoeae prevalence was 0.7% among women and 0.9% among men. Mycoplasma genitalium was found in 11% and 5.6% of women and men, respectively. Asymptomatic men and women had similar distribution patterns of microorganisms as those with urogenital symptoms, with the exceptions of Neisseria gonorrhoeae– and Mycoplasma genitalium–infected men who declared symptoms more frequently. Of 158 men with urogenital symptoms, 55% were test-negative. Of 129 women with urogenital symptoms, 12% were test-negative.

Conclusions
This study reveals a complex picture, where a large number of multi-positive tests made it complicated to correlate urogenital symptoms with microorganisms. A high number of test-negative but symptomatic patients indicate a need of searching for additional pathogens.
Just-in-Time Qualitative Research
Authors: Jairath Nalini N. , Benetato Bonnie B. , O’Brien Sandra L. , Griffin Agazio Janice B. 
Published: April 2021

Background
Methodological guidelines are required to ensure both the rigor and feasibility of just-in-time, qualitative research addressing the human experience and response to the COVID-19 pandemic and major public health crises.

Objectives
This article presents methodological guidelines for just-in-time qualitative research based on our current, pandemic-relevant research.

Methods
The processes followed while conducting two longitudinal, online qualitative studies addressing the lived experience and response to the COVID-19 pandemic were analyzed. Methodological challenges faced were then identified, and specific design and implementation guidelines were developed. The ways in which these guidelines can be applied to conduct just-in-time research during the COVID-19 pandemic and future public health crises were further delineated using examples from our pandemic-relevant research.

Results
Six guidelines were identified: (a) capitalize on fast track review and reporting processes; (b) prioritize accessibility during sample specification and selection; (c) optimize recruitment and retention strategies; (d) maximize current and future data use through strategic research design; (e) tailor data collection to participants’ characteristics, preferences, and priorities; and (f) incorporate timeline mapping of personal and contemporaneous phenomena.

Discussion
Public health measures taken to slow disease spread during the current COVID-19 pandemic and future public health crises may slow the pace of research and make its implementation all the more challenging. However, just-in-time qualitative research advances our understanding of the human experience and response to the COVID-19 and major public health crises. It also complements existing behavioral theory and research. The guidelines presented may assist researchers to initiate necessary qualitative research more rapidly, with fewer logistic challenges, and with methodological rigor. They may also help expand research on groups experiencing collateral effects of the pandemic and major public health crisis. Lastly, the guidelines may support the development of more robust data for alternate analysis at a later date.

Summary:
The persistence of health care disparities along racial and ethnic lines highlights the complex and multifactorial nature of this national concern. The paucity of physicians ethnically underrepresented in medicine to treat an ever-growing heterogeneous population inherently contributes to these ongoing disparities. The authors proposed an approach to improve the representation of physicians underrepresented in medicine in their plastic surgery residency program. With a renewed commitment to ethnic diversity and inclusion, a multifaceted recruitment and retention approach was implemented at the University of Pennsylvania plastic and reconstructive surgery residency program from 2015 to 2020 (5 academic years). A retrospective review of the demographics of the program’s residents was then assessed over the past 9 academic years for comparison (2011 to 2020). The representation of underrepresented-in-medicine residents within the plastic and reconstructive surgery residency program steadily increased with the implementation of this multifaceted approach, reaching an unprecedented high. Currently, 29 percent of all residents are underrepresented in medicine and 29 percent are female, some of whom are also underrepresented in medicine. Although the female representation is on par with the national average, the underrepresented-in-medicine representation is far greater than the national average. As a result of this multifaceted approach, the representation of African American and Latino plastic surgery residents at the University of Pennsylvania now far exceeds current national averages. Unfortunately, the representation of Native American and Alaskan Natives is still lacking, despite the program’s broadened recruitment efforts. The success of this experience describes a successful strategy that institutions can implement to enhance underrepresented-in-medicine representation among its plastic surgery trainees.

Published: April 2021

Background:
Financial key performance indicators are often used to evaluate performance. Understanding of key performance indicators can be crucial for career advancement and bargaining leverage in resource negotiations. This study aimed to identify the most important key performance indicators used in surgical funding requests and understand how to use these metrics in clinical practice.

Methods:
In two tertiary medical centers, funding requests for surgeon gap support (2019 to 2020) and equipment (2017 to 2019) within departments of surgery were reviewed. The requesting department, approval status, and amount allotted were recorded. In requests for gap support, projections for contribution margin, operating room volume, charges, collections, and relative value units were tracked. Projected contribution margin and cost savings were recorded for equipment funding requests.

Results:
There were 40 gap support and 24 equipment requests, and all were approved. Most gap support requests included collections (90.0 percent), charges (87.5 percent), operating room cases (80.0 percent), relative value units (77.5 percent), and hospital contribution margin (77.5 percent). The most represented departments were general surgery (37.5 percent), neurosurgery (22.5 percent), and plastic surgery (15.0 percent). The departments that submitted the most equipment requests were general surgery (28.0 percent) and neurosurgery (28.0 percent). Most requests included projections for contribution margin (95.8 percent) and cost savings (87.4 percent). Projected hospital contribution margin correlated with the amount of funds allotted for surgeon support (r = 0.409; p = 0.022).

Conclusions:
This multicenter study identified the importance of using key performance indicators for a successful financial outcome in funding requests. In addition, the authors demonstrate the need for surgeons to understand their own key performance indicators. Surgeons should advocate for increased transparency to better understand their financial contributions and performance.

Authors: Kraenzlin Franca , Chopra Karan , Kokosis George , Venturi Mark L. , Mesbahi Ali , Nahabedian Maurice Y. 
Published: April 2021

Background:
Prepectoral reconstruction using prosthetic devices has demonstrated a notable increase in popularity and confers a number of advantages over subpectoral placement, including minimal animation, no pain secondary to muscle spasm, and less device displacement or malposition. As such, more women with implants in the dual-plane position are seeking a remedy for animation deformities, chronic pain caused by muscle spasm, and implant malposition. The purpose of this study was to review outcomes following the conversion from subpectoral to prepectoral implant placement.

Methods:
This was a retrospective review of 63 patients who underwent breast implant conversion from the subpectoral plane to the prepectoral plane from 2009 to 2019.

Results:
A total of 73 implant pocket conversions from subpectoral to prepectoral were performed on 41 women who met inclusion criteria for this study. The mean time interval from the initial subpectoral operation to the prepectoral conversion was 1608.4 days. The reasons cited for prepectoral conversion was animation deformity (87.8 percent), significant levels of pain related to the implant (34.1 percent), capsular contracture (26.8 percent), or asymmetries and implant displacements (9.8 percent); 7.8 percent of individuals continued to experience their presenting symptom after plane conversion. Rippling and wrinkling were noted in 19.5 percent of individuals and edge visibility was documented in 4.9 percent. Complication rates were low, and no patients experienced necrosis of the mastectomy flap or nipple-areola complex.

Conclusions:
The use of prepectoral conversion for revision implant-based breast reconstruction successfully resolves animation deformity. This technique can be reliably and safely performed in a variety of patient demographics.

Early Diagnosis of HIV-1 and HIV-2 Using Cobas HIV-1/HIV-2 Qualitative Test: A Novel Qualitative Nucleic Acid Amplification Test for Plasma, Serum, and Dried Blood Spot Specimens
Authors: Hans Lucia , Allmen Nicole von , Edelmann Anke , Hofmann Jörg , Nilsson Alex Y. , Simon Christian O. , Seiverth Britta , Gohl Peter , Carmona Sergio 
Published: April 2021

Background:
Nucleic acid amplification tests (NATs) minimize the time from HIV infection to diagnosis, reducing transmission during acute HIV. NATs are especially useful for diagnosing HIV in children younger than 18 months and discriminating between HIV-1 and HIV-2.

Methods:
We evaluated the performance of the cobas HIV-1/HIV-2 qualitative (cobas HIV-1/2 Qual) test for use on cobas 6800/8800 Systems. The results of adult plasma and serum samples and pediatric dried blood spots were compared with those of the recomLine HIV-1 & HIV-2 Immunoglobulin G serological test and COBAS AmpliPrep/COBAS TaqMan HIV-1 qualitative test, v2.0. Genotype inclusivity and limits of detection were determined, and sensitivity on seroconversion panels was compared with that in the Bio-Rad Geenius HIV 1/2 Confirmatory Assay, Abbott ARCHITECT HIV Ag/Ab Combo serological test, and cobas TaqScreen MPX, v2.0.

Results:
Concordance of cobas HIV-1/2 Qual test with the comparator serological test and COBAS AmpliPrep/COBAS TaqMan test was ≥99.6% with all sample types. Reactivity with all HIV genotypes was 100%. LOD in plasma samples was 14.8, 12.6, and 27.9 copies/mL for HIV-1 group M, HIV-1 group O, and HIV-2, respectively, with similar results for serum samples. LOD in dried blood spots was 255 copies/mL for HIV-1 and 984 copies/mL for HIV-2. HIV infection was detected 18.9 days and 8.5 days earlier than the confirmatory and serological assays, respectively, and at a similar time to the NAT.

Conclusions:
The cobas HIV-1/2 Qual test enables early and accurate diagnoses of HIV-1 and HIV-2 in adults and children across sample types. The assay could help avert transmission during acute HIV, simplify HIV diagnostic algorithms, and promote the survival of HIV-infected children.
