Abstract
Chamomile (Matricaria chamomilla) is a plant with known antimicrobial, anti-inflammatory, and analgesic properties. Homeopathic drops containing chamomile extract are often used for ear pain and chronic ear infections. We aimed to evaluate the antimicrobial effect of over-the-counter eardrops containing chamomile against organisms causing bacterial conjunctivitis and otitis externa. Liquid cultures of Streptococcus aureus and Pseudomonas aeruginosa were exposed to increasing concentrations of eardrops containing chamomile extract. Liquid cultures of S. aureus and Streptococcus pneumoniae were exposed to increasing concentrations of chamomile eye drops for 5, 10, 15, and 45 min. Colony forming units (CFUs) were assessed after 18 h. Viability assays for these organisms were performed using the resazurin microdilution assay. We observed a reduction in the number of P. aeruginosa CFUs when the bacteria were exposed to any of the three concentrations of the chamomile drops as early as 5 min, with maximal reduction upon exposure to the 30% concentration at 45 min. Reduction in S. aureus CFUs, on the other hand, was observed for all three concentrations as maximal in the 5 min of exposure. We observed a marked reduction in the number of S. aureus CFUs upon exposure to any of the three preparations of chamomile-containing eye drops, which was almost immediate at 10% concentration. Streptococcus pneumoniae reduction happened at 5 min and continued through the 45-min observation period for all three concentrations. Our findings suggest that over-the-counter ear drops containing chamomile extract could potentially be used as a non-prescription treatment for mild cases of otitis externa and bacterial conjunctivitis.

Abstract
OBJECTIVE Primary repair in the first six months of life is routine for tetralogy of Fallot, complete atrioventricular septal defect, and ventricular septal defect in high-income countries. The objective of this analysis was to understand the utilization and outcomes of palliative and reparative procedures in high versus middle-income countries. METHODS The World Database of Pediatric and Congenital Heart Surgery identified patients who underwent surgery for: tetralogy of Fallot, complete atrioventricular septal defect, and ventricular septal defect. Patients were categorized as undergoing primary repair, repair after prior palliation, or palliation only. Country economic status was categorized as lower middle, upper middle, and high, defined by the World Bank. Multiple logistic regression models were utilized to identify independent predictors of hospital mortality. RESULTS Economic categories included high (n = 571, 5.3%), upper middle (n = 5,342, 50%), and lower middle (n = 4,793, 49.7%). The proportion of patients and median age with primary repair were: tetralogy of Fallot, 88.6%, 17.7 months; complete atrioventricular septal defect, 83.4%, 7.7 months; and ventricular septal defect, 97.1%, ten months. Age at repair was younger in high income countries (P < .0001). Overall mortality after repair was lowest in high income countries. Risk factors for hospital mortality included prematurity, genetic syndromes, and urgent or emergent operations (all P < .05). CONCLUSIONS Primary repair was selected in >90% of patients, but definitive repair was delayed in lower and upper middle income countries compared with high-income countries. Repair after prior palliation versus primary repair was not a risk factor for hospital mortality. Initial palliation continues to have a small but important role in the management of these three specific congenital heart defects.

Abstract
BACKGROUND Mortality associated with the correction of congenital heart disease has decreased to approximately 2% in developed countries and major adverse events are uncommon. Outcomes in developing countries are less well defined. The World Database for Pediatric and Congenital Heart Surgery was utilized to compare mortality and adverse events in developed and developing countries. METHODS A total of 16,040 primary procedures were identified over a two-year period. Centers that submitted procedures were dichotomized to low/middle income (LMI) and high income (HI) by the Gross National Income per capita categorization. Mortality was defined as any death following the primary procedure to discharge or 90 days inpatient. Multiple logistic regression models were utilized to identify independent predictors of mortality. RESULTS Of the total number of procedures analyzed, 83% (n = 13,294) were from LMI centers. Among all centers, the mean age at operation was 2.2 years, with 36% (n = 5,743) less than six months; 85% (n = 11,307) of procedures were STAT I/II for LMI centers compared with 77% (n = 2127) for HI centers (P < .0001). Overall mortality across the cohort was 2.27%. There was a statistical difference in mortality between HI centers (0.55%) versus LMI centers (2.64%) (P < .0001). After adjustment for other risk factors, the risk of death remained significantly higher in LMI centers (odds ratio: 2.36, 95% confidence interval: 1.707-3.27). CONCLUSION Although surgical expertise has increased across the globe, there remains a disparity with some outcomes associated with the correction of congenital heart disease between developing and developed countries. Further studies are needed to identify specific opportunities for improvement.

Abstract
Clustered Regularly Interspaced Short Palindromic repeats (CRISPR)-Cas systems rapidly raised from a bacterial genetic curiosity to the most popular tool for genetic modifications which revolutionized the study of microbial physiology. Due to the highly conserved nature of the CRISPR locus in Mycobacterium tuberculosis, the etiological agent of one of the deadliest infectious diseases globally, initially, little attention was paid to its CRISPR locus, other than as a phylogenetic marker. Recent research shows that M. tuberculosis has a partially functional Type III CRISPR, which provides a defense mechanism against foreign genetic elements mediated by the ancillary RNAse Csm6. With the advent of CRISPR-Cas based gene edition technologies, our possibilities to explore the biology of M. tuberculosis and its interaction with the host immune system are boosted. CRISPR-based diagnostic methods can lower the detection threshold to femtomolar levels, which could contribute to the diagnosis of the still elusive paucibacillary and extrapulmonary tuberculosis cases. In addition, one-pot and point-of-care tests are under development, and future challenges are discussed. We present in this literature review the potential and actual impact of CRISPR-Cas research on human tuberculosis understanding and management. Altogether, the CRISPR-revolution will revitalize the fight against tuberculosis with more research and technological developments.

Abstract
With a growing speaking Spanish population in the USA, it is necessary to help meet their healthcare needs. The Paul L. Foster School of Medicine is located in El Paso at the US-Mexico border. The medical Spanish curriculum is required for all medical students and begins on their first day of medical school, with conversational Spanish and medical Spanish through the preclerkship years. One of the key elements to the success of this course is the use of instructors with expertise in language instruction with an emphasis on task-based instruction. In addition to language instruction, this course also emphasizes instruction and experience in the culture of the US-Mexico border region. While taught medical Spanish, students are also prompted to understand when their skills are not adequate for the situation, in which case they need to enlist a skilled translator. Students report that, on a daily basis, they productively use what they learned in this preclerkship curriculum.

Abstract
Background: Studies show that the introduction of early public health interventions correlates with decreased rates of transmission and reductions in mortality resulting from epidemic or pandemic events. Methods: Medical educators and students from Texas Tech University Health Sciences Center El Paso created the El Paso-Health Education and Awareness Team (EP-HEAT) to educate at-risk populations in the border region. The English and Spanish material created by EP-HEAT included information about disease symptoms, transmission, preventive measures and mental health resources. An online, anonymous survey was distributed to attendees to obtain feedback on the provided coronavirus disease (COVID-19) educational material. Results: The results showed that over 90% of participants agreed that the informational pamphlets increased their awareness and knowledge of COVID-19. Conclusions: In this study, educators and students created COVID-19-related material in virtual workshops and pamphlets, designed to increase knowledge about COVID-19, mitigate the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and how to address mental health issues related to the pandemic. A majority of participants agreed or strongly agreed that the COVID-19 material developed by EP-HEAT helped raise awareness, understanding, and the importance of education about SARS-CoV-2/COVID-19.

Abstract
Background: CDC guidelines have recommended coronavirus disease-19 (COVID-19) vaccination for all people 5 years and older, including people who are breastfeeding. Breast milk has shown to be a valuable source of protection for immune-immature neonates. It has been shown that breast milk from mothers who have received vaccinations can transfer antibodies. Aim/Objective: This systematic review and meta-analysis investigate the presence of antibodies to SARS-CoV-2 in human breast milk after vaccination. Methods: Studies that evaluated immunoglobulins in breast milk of women receiving a SARS-CoV-2 vaccination were included. PubMed, Embase, Web of Science were searched for articles published between December 1, 2019 and September 30, 2021. Data from relevant articles were extracted manually or by WebPlotDigitizer version 4.1 to obtain the numeric values of antibody levels on peak days and the peak day then condensed into Excel. Additional raw data and information were supplied by corresponding authors. Results: One hundred ninety-two articles were obtained from the search. After excluding duplicates, screening titles and abstracts, 18 cohort studies were identified. For the rate of SARS-CoV-2 antibodies in breast milk after the first vaccine dose but before the second vaccine dose, we found 64% (95% CI 51-78%) were positive for IgA and 30% (95% CI 13.1-46%) were positive for IgG. For the rate for SARS-CoV-2 antibodies in breast milk after the second vaccine dose, we found 70% (95% CI 55-86%) were positive for IgA and 91% (95% CI 80-103%) were positive for IgG. Conclusions: Our analysis of the data published worldwide showed high rates of positivity for antibodies in breast milk following COVID-19 immunizations. Further research is necessary to find if the rate of positivity of IgA and IgG against SARS-CoV-2 in breast milk persists months after the full immunization, and their impact on the prevention of SARS-CoV-2 infection in infants.

Abstract
UNLABELLED The integration of basic science into clinical clerkships continues to be a challenge in medical curricula. We developed an integrated session for 3rd year medical students enrolled in OB-Gyn/Pediatric Block. The session focused on transplacental and perinatal infections, and consisted of a student-driven pedagogy activity in which students were required to explain the basic science principles behind the pathophysiology of the clinical presentations, the work-up, and the treatment of the infections. This approach helps students understand how basic science knowledge informs clinical practice and potential increase clerkship-level students' confidence as it makes them serve as leaders of active learning modules. SUPPLEMENTARY INFORMATION The online version contains supplementary material available at 10.1007/s40670-021-01485-7.

Abstract
Health systems worldwide are facing unprecedented challenges, as a result of a convergence of major threats to our social and population health systems. For an epidemic of any magnitude, prevention and preparation by healthcare personnel in clinical settings are essential, both locally and globally. The need for the development of domestic and international training programs in the expanding field of emerging and reemerging infectious diseases is well recognized but particularly urgent at this time. Interprofessional education plays key roles in infectious diseases (ID) and in training the new generation of ID-related specialists.

Abstract
The established thinking is that host response, rather than M. leprae strain variation, is the reason for the broad variation of symptoms in the leprosy disease spectrum Recent discoveries suggest that macrophage polarization also plays a significant role in the spectrum of leprosy disease but to what degree it contributes is not fully established. Utilizing DNA from three different strains of M. leprae DNA to stimulate human macrophages under three polarization conditions we observed, that the transcriptome upon stimulation with DNA from M. leprae strain Thai-53 was larger compared to strains NHDP and Br4923, independent of the macrophage polarization condition. We also found that macrophage polarization affects the responses to M. leprae DNA, with up-regulation of numerous interferon stimulated genes. These findings provide a deeper understanding of the role of macrophage polarization in the recognition of M. leprae DNA, with the potential to improve leprosy treatment strategies.
Infection with Mycobacterium leprae, the causative organism of leprosy, is still endemic in numerous parts of the world including the southwestern United States. The broad variation of symptoms in the leprosy disease spectrum range from the milder tuberculoid leprosy (paucibacillary) to the more severe and disfiguring lepromatous leprosy (multibacillary). The established thinking in the health community is that host response, rather than M. leprae strain variation, is the reason for the range of disease severity. More recent discoveries suggest that macrophage polarization also plays a significant role in the spectrum of leprosy disease but to what degree it contributes is not fully established. In this study, we aimed to analyze if different strains of M. leprae elicit different transcription responses in human macrophages, and to examine the role of macrophage polarization in these responses. Genomic DNA from three different strains of M. leprae DNA (Strains NHDP, Br4923, and Thai-53) were used to stimulate human macrophages under three polarization conditions (M1, M1-activated, and M2). Transcriptome analysis revealed a large number of differentially expressed (DE) genes upon stimulation with DNA from M. leprae strain Thai-53 compared to strains NHDP and Br4923, independent of the macrophage polarization condition. We also found that macrophage polarization affects the responses to M. leprae DNA, with up-regulation of numerous interferon stimulated genes. These findings provide a deeper understanding of the role of macrophage polarization in the recognition of M. leprae DNA, with the potential to improve leprosy treatment strategies.

Abstract
BACKGROUND There continues to be a disjoint between the emergence of new diagnostic technologies and venues to train new physicians on how to apply them. Next-generation sequencing (NGS) has become a very important tool for a wide range of clinical applications. Technical complexity and cost have been the major obstacles in incorporating these technologies into the classroom. GOAL FOR INNOVATION We opted to use the MinION, which is a new portable DNA sequencer that can produce data in real-time at a relatively low cost, for a NGS hands-on workshop with medical students. STEPS TAKEN We conducted a pilot NGS hands-on practical module in order to expose an interested group of medical students to this new portable sequencer device. A pre- and post-survey, using a Likert-type scale survey items and open-ended questions, evaluated participant resistance to new diagnostic tools, familiarity with NGS, and likelihood to use a portable sequencer in clinical practice. OUTCOMES Prior to participating in our learning workshop, students did not understand how to incorporate NGS into clinical practice, and expressed that cost and prior training/knowledge were among the limiting factors in their likelihood to use NGS as a diagnostic tool. After participating in the module, students' responses demonstrated a shift in their understanding of the scientific principles and applications of NGS (pre- and post-survey scores p < 0.05). REFLECTION The hands-on experience not only helped students become closer to and more comfortable with NGS, but also served as a venue to discuss the science and application of this technology in medicine. Such discussion helped to provide participants with current "genetic literacy" that is often incompletely covered in the typical undergraduate medical education curriculum.

Abstract
There is a shortage of residents in the infectious diseases (IDs) specialty due to a lack of interest in this field. If the choice of an ID subspecialty is linked to medical school experiences, then how we teach microbiology and immunology could be a factor in the declining interest in the field. We sought to determine whether experiential learning activities on host-pathogen research might improve students' interests and attitudes toward medical microbiology and immunology. Experiential learning of medical students undertaking research project on microbiology/immunology leads to subjective attitude changes (i.e., increased science motivation, confidence, and knowledge) and the development of a new social niche. It also lets students learn new scientific techniques and use novel technological devices, which have an impact in the experiential learning of basic sciences such as microbiology and immunology. The results of this study support the idea of a beneficial effect of experiential learning, which may rekindle interest of medical students in the field of infectious diseases.

Abstract
The optimal training of the highly specialized congenital heart surgeon is a long and complex process, which is a significant challenge in most parts of the world. The World Society for Pediatric and Congenital Heart Surgery (WSPCHS) has established the Global Council on Education for Congenital Heart Surgery as a nonprofit organization with the goal of assessing current training and certification and ultimately establishing standardized criteria for the training, evaluation, and certification of congenital heart surgeons around the world. The Global Council and the WSPCHS have reviewed the present status of training and certification for congenital cardiac surgery around the world. There is currently lack of consensus and standardized criteria for training in congenital heart surgery, with significant disparity between continents and countries. This represents significant obstacles to international job mobility of competent congenital heart surgeons and to the efforts to improve the quality of care for patients with Congenital Heart Disease worldwide. The purpose of this article is to summarize and document the present state of training and certification in congenital heart surgery around the world.

Abstract
Stone consolidants have been widely used to protect historical monuments. Consolidants and hydrophobic formulations based on the use of tetraethoxysilane (TEOS) and alkylalkoxysilanes as precursors have been widely applied, despite their lack of solubility in water and requirement to be applied in organic media. In the search for a “greener” alternative based on silicon that has potential use in this field, the use of tetrakis(2-hydroxyethyl)silane (THEOS) and tris(2-hydroxyethyl)methyl silane (MeTHEOS) as precursors, due their high water solubility and stability, is proposed in this paper. It is already known that THEOS and MeTHEOS possess remarkable compatibility with different natural polysaccharides. The investigated approach uses the water-soluble silanes THEOS–chitosan and MeTHEOS–chitosan as a basis for obtaining hybrid consolidants and hydrophobic formulations for the conservation of siliceous and calcareous stones. In the case of calcareous systems, their incompatibility with alkoxysilanes is known and is expected to be solved by the developed hybrid consolidant. Their application in the conservation of building stones from historical and archeological sites from Guanajuato, México was studied. The evaluation of the consolidant and hydrophobic formulation treatment was mainly conducted by determining the mechanical properties and contact angle measurements with satisfactory results in terms of the performance and compatibility with the studied stones.

Abstract
COVID-19 has ravaged the medical, social, and financial landscape across the world, and the USA-Mexico border is no exception. Although some risk factors for COVID-19 severity and mortality have already been identified in various ethnic cohorts, there remains a paucity of data among Hispanics, particularly those living on borders. Ethnic disparities in COVID-19 outcomes in Hispanic and black populations have been reported. We sought to identify the clinical presentation, treatment, laboratory, and imaging characteristics of 82 Hispanic patients in a county hospital and describe the factors associated with rates of hospitalization, intensive care unit (ICU) admission, and mortality. The most common comorbidities were hypertension (48.8%) and diabetes mellitus (DM) (39%), both found to be associated with hospitalization and mortality, while only DM was associated with increased rate of ICU admission. Multivariable analysis showed that individuals with fever, low oxygen saturation (SpO2), nasal congestion, shortness of breath, and DM had an increased risk of hospitalization. Individuals with fever, decreased levels of SpO2, and advanced age were found to be associated with an increased risk of death. The most common cause of death was respiratory failure (28.9%), followed by shock (17.8%) and acute kidney injury (15.6%). Our findings are critical to developing strategies and identifying at-risk individuals in a Hispanic population living on borders. Research aiming to identify key evidence-based prognostic factors in our patient population will help inform our healthcare providers so that best interventions can be implemented to improve the outcomes of patients with COVID-19.

Abstract
The glycol alkoxysilanes, tetrakis(2-hydroxyethyl)silane (THEOS), and tris(2-hydroxyethyl)methyl silane (MeTHEOS) are water soluble derivatives of tetraethoxysilane (TEOS) and methyltriethoxysilane (MeTEOS) and precursors of the system silane-chitosan reviewed in this work. The glycol modified alkoxysilanes are obtained by transesterification reaction of TEOS or MeTEOS with ethylene glycol. The reaction evolution is monitored by 29 Si NMR. It is possible to observe the formation of the various species of glycol alkoxysilanes in equilibrium as the reaction proceeds showing that the oligomers formation is favored at longer reaction times with the final product tendency to gel keeping the complete water solubility. The glycol alkoxysilanes are synthesized at moderated reaction conditions, by using the Piers-Rubinsztajn (PR) reaction. Additionally, it is already known that THEOS is compatible with different natural polysaccharides as chitosan and the same behavior has been demonstrated in this work for MeTHEOS. Several reports refer studies regarding the system THEOS-polysaccharides to synthesize hybrid materials. The system THEOS-chitosan is known but the characterization as well as the way silane-chitosan interact has not been studied in detail. In the present report, chemical evidence of the covalent interactions THEOS- and MeTHEOS-chitosan based on NMR studies (13 C and 29 Si) are presented as intended.

Abstract
Disease-associated alterations of the intestinal microbiota composition, known as dysbiosis, have been well described in several functional gastrointestinal (GI) disorders. Several studies have described alterations in the gastric microbiota in functional dyspepsia, but very few have looked at the duodenum.Here, we explored the upper GI tract microbiota of inpatients with upper GI dyspeptic symptoms, and compared them to achalasia controls, as there is no indication for an esophagogastroduodenoscopy in healthy individuals.We found differences in the microbiota composition at the three sites evaluated (ie, saliva, stomach and duodenum). Changes observed in patients with dyspepsia included an increase in Veillonella in saliva, an oral shift in the composition of the gastric microbiota, and to some degree in the duodenum as well, where an important abundance of anaerobes was observed. Metabolic function prediction identified greater anaerobic metabolism in the stomach microbial community of patients with dyspepsia. Proton pump inhibitor use was not associated with any particular genus. Co-abundance analysis revealed Rothia as the main hub in the duodenum, a genus that significantly correlated with the relative abundance of Clostridium, Haemophilus, and ActinobacillusWe conclude that patients with upper GI symptoms consistent with dyspepsia have alterations in the microbiota of saliva, the stomach, and duodenum, which could contribute to symptoms of functional GI disorders.

Abstract
The infectious diseases (ID) specialty continues to be in crisis due to a lack of interest by residents in the recruitment pool. It is possible that enhancing and innovating how microbiology is taught in medical school could increase the interest in ID. We need to improve teaching of preclinical medical microbiology and immunology by incorporating advancements in education and learning technologies to reignite the interest in the field. The shortage of ID specialists has important implications in our fight against ID threats such as the current COVID-19 global pandemic. In order to address this problem, we need to perform extensive research to identify the issues that medical learners and trainees are facing as they progress through their medical education towards the ID specialty.

Traditional phenotypic drug susceptibility testing for Mtb is costly and time consuming, while PCR-based methods are limited to selected target loci. We herein utilized a portable, USB-powered, long-read sequencing instrument (MinION), to investigate Mtb genomic DNA from clinical isolates to determine the presence of anti-TB drug-resistance conferring mutations. Data analysis platform EPI2ME and antibiotic-resistance analysis using the real time ARMA workflow, identified Mtb species as well as extensive resistance gene profiles. The approach was highly sensitive, being able to detect almost all described drug resistance conferring mutations based on previous whole genome sequencing analysis. Our findings are supportive of the practical use of this system as a suitable method for the detection of antimicrobial resistance genes, and effective in providing Mtb genomic information. Future improvements in the error rate through statistical analysis, drug resistance prediction algorithms and reference databases would make this a platform suited for the clinical setting. The small size, relatively inexpensive cost of the device, as well as its rapid and simple library preparation protocol and analysis, make it an attractive option for settings with limited laboratory infrastructure.

Abstract
The literature on ocular microbiome has grown tremendously over the past decade, and our knowledge of the different aspects and roles in homeostasis and protection is continuously growing. The development of 16 S rRNA sequencing has allowed the field to characterize communities of bacteria in health and ocular disease. Efforts should continue to further elucidate the interplay between microbiome and key players, such as age, comorbidities, and contact lens usage in order to have better control of the sight-threatening complications.

Abstract
Intestinal microbiota alterations have been found to be directly related to a wide range of disease states in humans, including multiple sclerosis (MS). The etiology of MS is highly debated and subsequently, there is no cure. Research dedicated to MS and its murine model, experimental autoimmune encephalomyelitis (EAE), have found that dysbiosis of the gut microbiota may play a role in the disease state and severity. In this review, we discuss the characteristic dysbiosis in MS, the role commensal-derived ligands may have in the pathogenesis of the disease, and the possibility of targeting the microbiota as a future therapy.

Abstract
Lyme disease is an inflammatory disease caused by infection with Borrelia burgdorferi (Bb). Inflammatory sequelae of Bb infection appear to be refractory to antibiotics. An antimicrobial peptide with the ability to bind the DNA in the tissue could serve as a viable option of treatment for chronic complications of Lyme borreliosis. DNA of Bb can remain in tissues causing a prolonged inflammatory response that lead to chronic joint pain. Here we examined the effect of IL-26, a newly reported antimicrobial protein, against Bb DNA. An antimicrobial effect of IL-26 on the spirochete was observed. In human macrophages, IL-26 treated cells showed an increase in IRF activation upon Bb stimulation. Moreover, IL-26 treated macrophages showed an increased in phagocytic activity compared to untreated cells. Although no Bb DNA degradation was observed using a TUNEL assay run in an agarose gel, a Comet assay on whole bacteria showed cellular and Bb DNA degradation by IL-26. Our results showed that IL-26 (monomer and dimer) has not only the potential to control Bb growth in vitro, but it also enhances the anti-borrelial response of human macrophages. Further research aiming to characterize the role of IL-26 in controlling other aspects of the inflammatory response that could provide insight of its potential therapeutic applications are needed.

Abstract
Mycobacterium tuberculosis (Mtb) has the extraordinary ability to persist for decades within granulomas in the human host. These histopathological structures involved in both protection and pathogenesis, are subject to various influences from the host systemically and through micro-niche environments. Despite the fact that vitamin D (VD) has a key role in macrophage activation and mycobacterial clearance in the early stages of Mtb infection, the overall role of VD in granuloma maintenance or functionality has been scarcely studied. VD deficiency has long time been known to influence on gut microbiota composition, and recent studies have shown that it can also impact on respiratory microbiome. The human microbiota plays an important role in pathogen colonization resistance, and it has been proposed to play a potential role in TB pathogenesis. In this article, we have reviewed current knowledge on the interaction between VD, the lung microbiome and TB, and propose mechanisms by which the tuberculous granuloma's outcome could be modulated by these two factors. The determinants of the final fate of lung granulomas are still unclear, and deciphering the underlying drivers of Mtb infection outcome within those structures is of critical importance.

Abstract
Lyme disease (LD) is a multisystemic inflammatory disease caused by pathogenic spirochetes, belonging to the genospecies complex Borrelia burgdorferi sensu lato (B.b.s.l.). Around the world, distinct species of Ixodes tick vectors transmit different species of Borrelia. Despite the rising recognition and occurrence of tick-borne disease in Latin America, serology has proven to be inconclusive in detecting suspected LD cases. Recently, new B.b.s.l. strains or new related species have been described in Brazil, Uruguay, and Chile. This could explain the lack of confirmatory tests, such as indeterminate Western blots (WBs) and polymerase chain reactions, in detecting suspected LD cases in this region of the world. Future studies will need to determine the extension of novel B.b.s.l. species infections in ticks, reservoirs, and humans in Latin America. The existence of these new Borrelia genomic species should prompt the development of innovative diagnostic and clinical approaches.

Abstract
Growth is one of the most important characteristics of human development. This process occurs from the moment of conception through the final stages of puberty. There are multiple factors that contribute to growth in humans. Although it may seem complex, a pediatrician should note that growth can be fairly predictable. The advantage to predictable changes in growth is that clinicians should be able to promptly detect any deviation and evaluate it in a timely manner. One of the most helpful tools to assess changes in growth is the use of a growth chart. This article provides the clinician with the necessary tools to identify growth abnormalities, investigate appropriately to arrive at an accurate diagnosis, and either treat or, when indicated, provide a timely referral to a pediatric endocrinologist.

Abstract
Microneedling is a minimally invasive dermatological procedure in which fine needles are rolled over the skin to puncture the stratum corneum. This therapy is used to induce collagen formation, neovascularization and growth factor production of treated areas. It has been used in a wide range of dermatologic conditions, including androgenetic alopecia (AGA) and alopecia areata, among others. While there are a limited number of studies examining this therapy in the use of hair loss, microneedling has been successfully paired with other hair growth promoting therapies, such as minoxidil, platelet-rich plasma and topical steroids, and shown to stimulate hair follicle growth. It is thought that microneedling facilitates penetration of such first-line medications, and this is one mechanism by which it promotes hair growth. To date, the area most studied and with the most success has been microneedling treatment of AGA. While the current evidence does not allow one to conclude superiority of microneedling over existing standard therapies for hair loss, microneedling shows some promise in improving hair growth, especially in combination with existing techniques. This review summarizes the current literature regarding microneedling in the treatment of alopecia and calls for further studies to define a standard treatment protocol.

Abstract
BACKGROUND Pterygium inversum unguis (PIU) is characterized by the abnormal adherence of the hyponychium to the ventral surface of the nail plate. It can be both unsightly and painful, resulting in morbidity for patients. Gel polish is a popular nail cosmetic that has been reported to cause several complications. PIU may be another adverse outcome. OBJECTIVE To highlight a newly recognized adverse effect of a popular beauty technique. METHODS This retrospective and prospective case series reports 17 women who developed PIU after gel polish use. All study-related activities occurred at a University of Miami dermatology outpatient clinic. RESULTS All 17 subjects developed PIU after two to five years of gel polish application. Nine of 17 patients reported using both UVA and LED light to cure gel polish. Of the remaining eight, five used LED light only and three did not know or could not remember. All but two patients had a resolution of PIU a few weeks after switching from gel polish to regular polish manicures. CONCLUSION While it remains undiscerned whether PIU is related to chemicals present in the gel polish or to the application and/or removal process of such, patients and dermatologists should be aware of the potential risks of gel manicures.

Abstract
The World Society for Pediatric and Congenital Heart Surgery was founded with the mission to “promote the highest quality comprehensive cardiac care to all patients with congenital heart disease, from the fetus to the adult, regardless of the patient’s economic means, with an emphasis on excellence in teaching, research, and community service.” Early on, the Society’s members realized that a crucial step in meeting this goal was to establish a global database that would collect vital information, allowing cardiac surgical centers worldwide to benchmark their outcomes and improve the quality of congenital heart disease care. With tireless efforts from all corners of the globe and utilizing the vast experience and invaluable input of multiple international experts, such a platform of global information exchange was created: The World Database for Pediatric and Congenital Heart Disease went live on January 1, 2017. This database has been thoughtfully designed to produce meaningful performance and quality analyses of surgical outcomes extending beyond immediate hospital survival, allowing capture of important morbidities and mortalities for up to 1 year postoperatively. In order to advance the societal mission, this quality improvement program is available free of charge to WSPCHS members. In establishing the World Database, the Society has taken an essential step to further the process of global improvement in care for children with congenital heart disease.

Deposition and hydrolysis of serine dipeptide lipids of Bacteroidetes bacteria in human arteries: relationship to atherosclerosis. J Lipid Res 2017; 58:1999-2007.

Abstract
Multiple reaction monitoring-MS analysis of lipid extracts from human carotid endarterectomy and carotid artery samples from young individuals consistently demonstrated the presence of bacterial serine dipeptide lipid classes, including Lipid 654, an agonist for human and mouse Toll-like receptor (TLR)2, and Lipid 430, the deacylated product of Lipid 654. The relative levels of Lipid 654 and Lipid 430 were also determined in common oral and intestinal bacteria from the phylum Bacteroidetes and human serum and brain samples from healthy adults. The median Lipid 430/Lipid 654 ratio observed in carotid endarterectomy samples was significantly higher than the median ratio in lipid extracts of common oral and intestinal Bacteroidetes bacteria, and serum and brain samples from healthy subjects. More importantly, the median Lipid 430/Lipid 654 ratio was significantly elevated in carotid endarterectomies when compared with control artery samples. Our results indicate that deacylation of Lipid 654 to Lipid 430 likely occurs in diseased artery walls due to phospholipase A2 enzyme activity. These results suggest that commensal Bacteriodetes bacteria of the gut and the oral cavity may contribute to the pathogenesis of TLR2-dependent atherosclerosis through serine dipeptide lipid deposition and metabolism in artery walls.
