Helicobacter pylori infection in pregnant women: Gastrointestinal symptoms and pregnancy- related disorders. World J Clin Infect Dis 2023; 13:49-57. [DOI: 10.5495/wjcid.v13.i5.49] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 10/21/2023] [Accepted: 12/07/2023] [Indexed: 12/27/2023] [Imported: 12/27/2023] Open
Abstract
Helicobacter pylori (H. Pylori) is a gram-negative, flagellated and spiral-shaped bacterial pathogen that impacts approximately 46% among pregnant women globally and has been associated with various maternal-fetal complications. Iron deficiency anemia, fetal growth restriction, cardiovascular diseases, and insufficient nutrient absorption can be observed in pregnant women, as well as miscarriages and pregnancy-specific hypertensive disease, such as pre-eclampsia. Thus, the evidence supports the influence of H. pylori infection on fetal implantation/placentation failure, and positive strains of the cytotoxin-associated gene A of H. Pylori were reported as the most prevalent in these conditions. However, current knowledge indicates a relationship between this infection and the occurrence of hyperemesis gravidarum, characterized by frequent nausea and vomiting. Regarding the diagnosis of this bacterial infection, non-invasive approaches such as stool antigen test, urea breath test, and serological tests are more accepted during pregnancy, as they are easy to carry out and cost-effective. Finally, the bacteria eradication therapy should consider the risks and benefits for the pregnant woman and her child, with pharmacological intervention depending on the clinical presentation.

Liu XQ, Lu GZ, Yin DL, Kang YY, Zhou YY, Wang YH, Xu J. Analysis of clinical characteristics and risk factors between elderly patients with severe and nonsevere Omicron variant infection. World J Clin Infect Dis 2023; 13:37-48. [DOI: 10.5495/wjcid.v13.i4.37] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 11/02/2023] [Accepted: 11/13/2023] [Indexed: 11/22/2023] [Imported: 11/22/2023] Open
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to millions of confirmed cases and deaths worldwide. Elderly patients are at high risk of developing and dying from COVID-19 due to advanced age, decreased immune function, intense inflammatory response, and comorbidities. Shanghai has experienced a wave of infection with Omicron, a new variant of SARS-CoV-2, since March 2022. There is a pressing need to identify clinical features and risk factors for disease progression among elderly patients with Omicron infection to provide solid evidence for clinical policy-makers, public health officials, researchers, and the general public.
AIM To investigate clinical characteristic differences and risk factors between elderly patients with severe and nonsevere Omicron SARS-CoV-2 variant infection.
METHODS A total of 328 elderly patients with COVID-19 admitted to the Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 2022 to June 2022 were enrolled and divided into a severe group (82 patients) and a nonsevere group (246 patients) according to the diagnosis and treatment protocol of COVID-19 (version 7). The clinical data and laboratory results of both groups were collected and compared. A chi-square test, t test, Mann-Whitney U test, hierarchical log-rank test, univariate and multivariate logistic regression, and hierarchical analyses were used to determine significant differences.
RESULTS The severe group was older (84 vs 74 years, P < 0.001), included more males (57.3% vs 43.9%, P = 0.037), had a lower vaccination rate (P < 0.001), and had a higher proportion of comorbidities, including chronic respiratory disease (P = 0.001), cerebral infarction (P < 0.001), chronic kidney disease (P = 0.002), and neurodegenerative disease (P < 0.001), than the nonsevere group. In addition, severe disease patients had a higher inflammatory index (P < 0.001), greater need for symptomatic treatment (P < 0.001), longer hospital stay (P = 0.011), extended viral shedding time (P = 0.014), and higher mortality than nonsevere disease patients (P < 0.001). No difference was observed in the application of Paxlovid in the severe and nonsevere groups (P = 0.817). Oxygen saturation, cerebral infarction, and D-dimer were predictive factors for developing severe disease in patients with COVID-19, with D-dimer having an excellent role (area under the curve: 90.1%, 95%CI: 86.1-94.0%). In addition, D-dimer was a risk factor for developing severe COVID-19 according to multivariate stratified analysis.
CONCLUSION The clinical course of severe COVID-19 is complex, with a higher need for symptomatic treatment. D-dimer is a suitable biomarker for identifying patients at risk for developing severe COVID-19.

Abstract
The Centers for Disease Control and Prevention (CDC) is monitoring an epidemic of monkeypox infection in the United States. The outbreak is now global and more than 6900 cases have already been reported. There are 83 confirmed cases among children and adolescents, as shown in the report published on November 3, 2022, in the USA. However, monkeypox in pediatric patients is still infrequent (< 0.3% of total cases). Among cases in the United States, 16 cases were in children < 5 years, 12 in the age group 5-12 years, and 55 cases in adolescents 13-17 years old. In the adolescent age group, 89% were male. For children < 12 years of age, close physical contact with an adult household with monkeypox was the primary exposure, but for adolescents, male-to-male sexual contact was found more frequently. The CDC advised United States healthcare providers to remain vigilant for patients with a rash resembling monkeypox, even if there is no history of travel to a country with high risk. This article summarizes the history and epidemiology of monkeypox with a specific emphasis on clinical features and management in pediatric patients.

Abstract
BACKGROUND Brucellosis is endemic in India with seropositivity rates as high as 10% in children in the eastern states, yet the disease is not on the radar when a differential diagnosis of pyrexia of unknown origin (PUO) is being considered, especially in children in urban set-up. This may be because of the non-specific multitude of systemic symptoms seen in this disease and the lack of awareness among clinicians.
CASE SUMMARY We present a case of a 13-year-old boy, who came with a history of undulating fever for the past three and a half months, loss of appetite, and abdominal pain. The child had visited several pediatricians and was even admitted to a tertiary care hospital for PUO evaluation, but to no avail. He presented to us after three and half months of suffering and weight loss of more than 10% of body weight. His ultrasonography revealed thickening of the terminal ileum. His blood culture grew Brucella melitensis. A diagnosis of Brucellosis with terminal ileitis was made. Brucella serology by enzyme-linked immunoassay (ELISA) was positive for both IgG and IgM. He was treated with doxycycline and Rifampicin along with syrup multivitamin and zinc, for 6 wk. There was remarkable improvement with gain in 4 kg body weight within 2 mo of completing treatment. History revealed consumption of unpasteurized milk and contact with cattle.
CONCLUSION Clinical suspicion, detailed history, appropriate laboratory investigations are the three pillars for diagnosing Brucellosis in patients presenting with vague symptoms.

Abstract
Leishmaniasis is a vector-borne parasitic disease affecting millions of people worldwide. However, in the last decade, the number of cases has been reduced from well-documented endemic parts, but sporadic cases have been reported widely from various non-endemic areas, especially from the southern Himalayan zone. This raises concerns about the emergence of new ecological niches. This warrants a critical evaluation of key factors causing this rapid spread and possibly indigenous transmission. This mini-review article is aimed to briefly address the parasite, the vector, and the environmental aspects in the transmission of leishmaniasis in these new foci against a background of worldwide endemic leishmaniasis with a special focus on the southern Himalayan zone. As the lack of knowledge about the causative parasites, vectors, reservoir hosts, atypical presentations, and their management make the problem serious and may lead to the emergence of public health issues. The present works also reviewed the existing information regarding clinical variations, diagnostic methods, treatment, its outcome, and ignite for further research in these aspects of the disease.

Three-dimensional models of antigens with serodiagnostic potential for leprosy: An in silico study. World J Clin Infect Dis 2023; 13:1-10. [DOI: 10.5495/wjcid.v13.i1.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 12/28/2022] [Accepted: 02/02/2023] [Indexed: 02/27/2023] [Imported: 07/06/2023] Open
Abstract
BACKGROUND Leprosy is a disease caused by Mycobacterium leprae (M. leprae), an intracellular pathogen that has tropism and affects skin and nervous system cells. The disease has two forms of presentation: Paucibacillary and multibacillary, with different clinical and immunological manifestations. Unlike what occurs in the multibacillary form , the diagnostic tests for the paucibacillary form are nonspecific and not very sensitive, allowing the existence of infected individuals without treatment, which contributes to the spread of the pathogen in the population. To mitigate this contamination, more sensitive diagnostic tests capable of detecting paucibacillary patients are needed.
AIM To predict the three-dimensional structure models of M. leprae antigens with serodiagnostic potential for leprosy.
METHODS In this in silico study, satisfactory templates were selected in the Protein Data Bank (PDB) using Basic Local Alignment Search Tool to predict the structural templates of ML2038, ML0286, ML0050, and 85B antigens by comparative modeling. The templates were selected according to general criteria such as sequence identity, coverage, X-ray resolution, Global Model Quality Estimate value and phylogenetic relationship; Clustal X 2.1 software was used in this analysis. Molecular modeling was completed using the software Modeller 9v13. Visualization of the models was made using ViewerLite 4.2 and PyMol software, and analysis of the quality of the predicted models was performed using the QMEAN score and Z-score. Finally, the three-dimensional moels were validated using the MolProbity and Verify 3D platforms.
RESULTS The three-dimensional structure models of ML2038, ML0286, ML0050, and 85B antigens of M. leprae were predicted using the templates PDB: 3UOI (90.51% identity), PDB: 3EKL (87.46% identity), PDB: 3FAV (40.00% identity), and PDB: 1F0N (85.21% identity), respectively. The QMEAN and Z-score values indicated the good quality of the structure models. These data refer to the monomeric units of antigens, since some of these antigens have quaternary structure. The validation of the models was performed with the final three-dimensional structure - monomer (ML0050 and 85B antigens) and quaternary structures (ML2038 and ML0286). The majority of amino acid residues were observed in favorable and allowed regions in the Ramachandran plot, indicating correct positioning of the side chain and absence of steric impediment. The MolProbity score value and Verify 3D results of all models indicated a satisfactory prediction.
CONCLUSION The polarized immune response against M. leprae creates a problem in leprosy detection. The selection of immunodominant epitopes is essential for the development of more sensitive serodiagnostic tests, for this it is important to know the three-dimensional structure of the antigens, which can be predicted with bioinformatics tools.

Abstract
Coronavirus disease (COVID-19) was first identified in Wuhan, China and then rapidly spread all over the world. The World Health Organization declared a pandemic on March 11, 2020 as a result of COVID-19. As it has caused substantial morbidity and mortality, most countries took several measures to control its spread, including India. As of now, India has witnessed three major waves of COVID-19. Several measures like nationwide lockdown, active case finding, contact tracing, home isolation, and vaccination were taken. There was involvement of multiple sectors (including private and government) and community participation. During the pandemic, I was posted at a primary health centre in a rural setting in India. A rural primary care setting has its own limitations. All the steps taken had several challenges at the grassroots level. Therefore, through this article, I highlighted the challenges faced during the implementation of steps taken to battle the pandemic and the outcome.

Abstract
BACKGROUND During the peak of the coronavirus diseases 2019 (COVID-19) pandemic, clinicians actively studied the utility of various epidemiologic-clinical parameters to determine the prognosis for patients hospitalized with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Serum IgG antibody level, D-Dimer, C-reactive protein and neutrophil to lymphocyte ratio, etc. were studied to assess their association with the clinical course in hospitalized patients and predict who may be at increased risk for poor clinical outcome. However, the influence of SARS-CoV-2-anti-nucleocapsid-IgG antibody (IgG-N) sero-positivity on the clinical outcome of patients with COVID-19 is largely unknown.
AIM To study the influence of SARS-CoV-2 anti-nucleocapsid-IgG seropositivity on clinical course and diseases severity in hospitalized COVID-19 patients.
METHODS We conducted a retrospective study of adults admitted to a tertiary care community hospital in North Dakota with COVID-19. Included patients had severe COVID-19 disease or worse and so required supplemental oxygen on admission. They were serologically tested for SARS-CoV-2-anti-nuceocapsid-IgG (IgG-N). The IgG-N positive group were 26 patients and the IgG-N negative group had 33 patients. The groups received similar treatment for COVID-19 as approved by our healthcare system from Day 1 of admission until discharge or death. Measurable parameters for monitoring the patients’ clinical course included the following: Length of hospitalization (LOS), use of high flow nasal canula (HFNC), use of noninvasive bilevel positive pressure ventilation (BiPAP), admission into the intensive care unit, need for mechanical ventilation (VENT); and the patient outcome/discharge or death. Other variables included were age, gender and body-mass-index, and duration of symptoms before presentation. For each variable, the outcome was modeled as a function of SARS-CoV-2-IgG-N status (positive or negative) using a generalized linear model. For LOS-days, a negative binomial distribution was used as it had a better fit than a Poisson or Gaussian distribution as evidenced by a Pearson chi-square/df value closer to 1.0. All other outcomes utilized a binary logistic regression model.
RESULTS After a thorough examination of patient data, it was found that admission rates to the Intensive Care Unit, as well as the usage of BiPAP, HFNC and VENT support, in conjunction with patient outcomes, were not significantly different across IgG-N status. However, the LOS variable when assessed by IgG-N status was found to be significant (t value = 2.16, P value = 0.0349). IgG-N negative patients had higher than average LOS in comparison to IgG-N positive patients (15.12 vs 9.35 d). Even when removing the extreme value (an LOS of 158 d), IgG-N negative patients still had slightly higher than average stays (10.66 vs 9.35 d) but the relationship was no longer significant. For patient outcome/death, only age (numerical) was a significant predictor (F value = 4.66, P value = 0.0352). No other variables for any of the outcomes were significant predictors of clinical course or disease severity.
CONCLUSION Our study demonstrated that IgG-N seroconversion had no significant association with clinical outcomes in hospitalized COVID-19 patients.

Abstract
BACKGROUND Leishmaniasis is a neglected zoonotic disease, endemic in Sudan. Estimating this disease is very important to inform the health care policymakers and the governments to apply proper health and economic policies.
AIM To find out the frequency and distribution of human leishmaniasis based on sex and age for 5 years in the West Kordofan state, Sudan.
METHODS A 5-year retrospective study from 2016 through 2020 was carried out using local hospital records of leishmaniasis patients. The positive results were recorded after performing at least one of the following leishmaniasis standard tests: direct agglutination test, enzyme-linked immunosorbent assay and leishmania skin test. The sex and age of each patient were recorded. The collected data were analyzed using STATA package version 16.
RESULTS A total of 162443 patient records from 2016 to 2020 were retrieved. Of these, 4.39% were found to be positive for leishmaniasis. The disease has been more common in males (65.3%) than in females (34.7%). The highest reported prevalence (6.58%) was in patients 15-44 years, and the lowest prevalence (1.95%) was among patients ≥ 65 years.
CONCLUSION The results of the current study indicate that leishmaniasis is endemic in the study area even though the numbers of patients in the 5 consecutive years were varying. In addition, the disease was common in males and adults. The interpretation of these findings should take into consideration the absence of information about some important confounding factors.

Abstract
BACKGROUND Intestinal spirochetosis (IS) is caused by Brachyspira colonization of the gastrointestinal tract. Some patients are asymptomatic, while others present with gastrointestinal complaints such as abdominal pain, diarrhea, or gastrointestinal bleeding. However, the clinical significance of asymptomatic IS is unclear, and guidelines are lacking regarding decision to treat.
CASE SUMMARY A 73-year-old male with peptic ulcer disease and gastroesophageal reflux was evaluated for elevated liver enzymes. He was diagnosed with chronic hepatitis B virus and prescribed entecavir. Additionally, he was leukopenic and had stage 4 liver fibrosis on transient elastography. After 5 mo, the patient returned for esophagogastroduodenoscopy and screening colonoscopy. He denied any gastrointestinal symptoms at that time. Findings included grade I distal esophageal varices, mild portal hypertensive gastropathy, and patchy nodular gastric antral mucosa. On colonoscopy, several polyps were removed. Hematoxylin and eosin stain of mucosa adjacent to the polyps revealed a “false brush border,” and Steiner stain identified spirochetes adherent to the mucosa. These pathology findings confirmed the diagnosis of IS. He was managed conservatively with careful observation and without antibiotic therapy via a multidisciplinary approach between gastroenterology and infectious disease. He remained asymptomatic at the 7-wk follow-up.
CONCLUSION This case reports the finding of incidental, asymptomatic IS in a leukopenic patient with hepatitis B virus. Conservative management was appropriate.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) is a highly contagious viral illness which conventionally manifests with primarily respiratory symptoms and less commonly with cardiac involvement in various forms, such as pericarditis. Myocarditis and pericarditis have been reported in a variety of live and attenuated vaccines, such as smallpox and influenza. As of October 2021, no cases of pericarditis associated with COVID-19 vaccination have been published. We present two healthy male patients who present post COVID-19 vaccination with pericarditis diagnoses.
CASE SUMMARY A 21-year-old male with no significant past medical history presented with myalgia, chills, mild headache, and chest pain for two days. Patient received the Moderna COVID-19 vaccine the day prior to symptom onset. On presentation, electrocardiogram (ECG) revealed sinus rhythm with ST elevation, and troponin was elevated. Emergent cardiac catheterization was not significant for abnormalities. The primary diagnosis was acute pericarditis, and the patient was discharged on colchicine and indomethacin. Additionally, a 35-year-old male with no pertinent past medical history presented with fever, chills, weakness, nausea, vomiting, diarrhea, and retrosternal chest pain for three days. He received the Moderna COVID-19 vaccine four days prior to symptom onset. On presentation, troponin was elevated, and ECG revealed mild ST elevation. Left ventricular dysfunction with ejection fraction of 41% was reported on transthoracic echocardiogram. Patient was started on ibuprofen and colchicine for diagnosis of myopericarditis.
CONCLUSION These case reports highlight a potential unintended consequence, pericarditis, associated with COVID-19 vaccination that may not warrant invasive cardiac intervention.

Abstract
BACKGROUND Infected aortic aneurysms are uncommon and difficult to treat. We present a case of infected aortic aneurysm with recurrent nontyphoidal Salmonella bacteremia.
CASE SUMMARY A 68-year-old gentleman presented with non-specific symptoms and was found to have nontyphoidal Salmonella bacteremia and was treated with intravenous ceftriaxone. However his condition did not improve, and he developed a multiloculated right pleural effusion. Thoracocentesis was done to drain hemorrhagic pleural fluid. Chest computed tomography demonstrated descending thoracic aorta saccular aneurysm with periaortic hematoma likely due to recent bleed and extending to the right pleural cavity. He was referred to cardiothoracic surgery team and was planned for medical therapy in view of hemodynamic stability and no evidence of active leakage. He completed intravenous antibiotic for 5 wk and refused surgical intervention. Unfortunately, he was admitted twice for recurrent nontyphoidal Salmonella bacteremia. Finally, he agreed for surgical intervention and underwent endovascular aortic repair 3 mo later. Postoperatively, his condition remained stable with no recurrence of infection.
CONCLUSION Our case highlights the importance of high index of suspicion of infected aortic aneurysm in patients with Salmonella bacteremia with high-risk factors such as atherosclerosis.

Abstract
Discrimination is an age-old ‘illness’ irrespective of its context. Stigma is a common factor that has been associated with disability and coronavirus disease 2019. The public health impact of stigma on differently-abled people during this pandemic is not known and it is a poorly investigated and neglected area. It is important to address the current research need in the concerned area and its implications for public health policymaking and changes in practices that it requires. Together we can win the war against pandemics if we reduce the mental distancing in all perspectives.

Abstract
The introduction of coronavirus disease-2019 (COVID-19) as a global pandemic has contributed to overall morbidity and mortality. With a focus on understanding the immunology and pathophysiology of the disease, these features can be linked with the respective findings of imaging studies. Thus, the constellation between clinical presentation, histological, laboratory, immunological, and imaging results is crucial for the proper management of patients. The purpose of this article is to examine the role of imaging during the particular stages of severe acute respiratory syndrome coronavirus 2 infection – asymptomatic stage, typical and atypical COVID-19 pneumonia, acute respiratory distress syndrome, multiorgan failure, and thrombosis. The use of imaging methods to assess the severity and duration of changes is crucial in patients with COVID-19. Radiography and computed tomography are among the methods that allow accurate characterization of changes.

Zank A, Schulte L, Brandon X, Carstensen L, Wescott A, Schwan WR. Mutations of the brpR and brpS genes affect biofilm formation in Staphylococcus aureus. World J Clin Infect Dis 2022; 12:20-32. [DOI: 10.5495/wjcid.v12.i1.20] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 12/03/2021] [Accepted: 02/13/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND In the United States, Staphylococcus aureus (S. aureus) kills tens of thousands of individuals each year and the formation of a biofilm contributes to lethality. Biofilm-associated infections are hard to treat once the biofilm has formed. A new stilbene drug, labeled SK-03-92, was shown to kill S. aureus and affected transcription of two genes tied to a putative two-component system (TCS) we have named brpR (biofilm regulating protein regulator) and brpS (biofilm regulating protein sensor).
AIM To determine if BrpR and BrpS regulate biofilm formation, brpR and brpS mutants were assessed using biofilm assays compared to wild-type S. aureus.
METHODS A combination of biofilm and quantitative real-time-polymerase chain reaction assays were used. In addition, bioinformatic software tools were also utilized.
RESULTS Significantly more biofilm was created in the brpR and brpS mutants vs wild-type cells. Quantitative real-time polymerase chain reactions showed the brpS mutant had differences in transcription of biofilm associated genes that were eight-fold higher for srtA, two-fold lower for lrgA, and 1.6-fold higher for cidA compared to wild-type. Bioinformatic analysis demonstrated that the S. aureus brpR/brpS TCS had homology to streptococcal late-stage competence proteins involved in cell-death, increased biofilm production, and the development of persister cells.
CONCLUSION Our study suggests that brpR/brpS is a TCS that may repress S. aureus biofilm production and be linked to late-stage competence in S. aureus.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019 spread worldwide within only a few months. The screening and timely isolation of infected individuals have been regarded as an effective means of epidemic prevention and control. Therefore, effective screening of infected individuals plays a vital role in epidemic prevention and control. At present, reverse transcription-polymerase chain reaction (RT–PCR) is the main method for the in vitro detection of SARS-CoV-2. However, RT–PCR requires certified laboratories, expensive equipment, and trained technicians. Therefore, it is necessary to develop simpler and more convenient methods. Some studies have shown that the PepKAA peptide has a high affinity for the S protein of SARS-CoV-2. The tyrosine in PepKAA is labeled with 125I and used to design a radioimmunoassay kit for the detection of the S protein of SARS-CoV-2, which is of great significance for the early diagnosis of COVID-19.

Abstract
BACKGROUND In December 2019, coronavirus disease 2019 (COVID-19) was reported firstly in Wuhan, China. COVID-19 is currently a global pandemic.
AIM To assess the suitability of lymphocyte count as a biomarker of COVID-19 severity.
METHODS Five literature databases (PubMed/MEDLINE, Web of Science, Google Scholar, Embase, and Scopus) were searched to identify eligible articles. A meta-analysis was performed to calculate the standard mean difference (SMD) and 95% confidence interval (CI) of lymphocyte counts in coronaviral pneumonia cases.
RESULTS Eight studies, including 1057 patients, were integrated in the meta-analysis. Lymphocyte counts were associated with severe coronavirus (CoV) infection (SMD = 1.35, 95%CI: 1.97 to 0.37, P < 0.001, I2 = 92.6%). In the subgroup analysis stratified by prognosis, lymphocytes were associated with CoV infection mortality (n = 2, SMD = 0.42, 95%CI: 0.66 to 0.19, P < 0.001, I2 = 0.0%), severity (n = 2, SMD = 0.93, 95%CI: 1.20 to 0.67, P < 0.001, I2 = 0.0%), and diagnostic rate (n = 4, SMD = 2.32, 95%CI: 3.60 to 1.04, P < 0.001, I2 = 91.2%).
CONCLUSION Lymphocyte count may represent a simple, rapid, and commonly available laboratory index with which to diagnosis infection and predict the severity of CoV infections, including COVID-19.

Abstract
Government leaders have struggled to reduce the infection and deaths due to coronavirus disease 2019 (COVID-19) as well as to keep the economy and businesses open. There is a large variation of mortality and damage to economy among countries. One possible cause leading to the large variation is the manner in which countries have delt with COVID-19. Some countries or regions such as China, New Zealand, and Taiwan, acted quickly and aggressively by implementing border closures, lockdown, school closures, mass testing, etc. On the other hand, many European countries, United States, and Brazil delayed their decisions to implement these restrictions and measures. No study has assessed the correlation between gross domestic product (GDP) and COVID-19 mortality. In the present study, there was a negative correlation between GDP and COVID-19 mortality suggesting that countries that failed to control the virus (larger COVID-19 mortality) would see a larger decline in GDP. Governmental leaders should act fast and aggressively when making decisions because data shows that countries who have run after two hares have caught neither. Furthermore, citizens of each country need to do their own part by following guidelines and practicing social distancing and mask wearing, which are considered the most effective, easiest, and cheapest measures that can be taken, so that repeated lockdowns can be avoided.

Abstract
BACKGROUND Reports of leishmaniasis are scarce in North America. It is considered to be one of the neglected tropical diseases. It is seen in immigrants from endemic areas to United States. Treatments are not readily available in the United States. Untreated or inadequately treated cutaneous leishmaniasis not only causes localized disfigurement but can advance to more permanent and devastating mucosal disfigurement and perforation, if caused by a species that can also cause mucocutaneous leishmaniasis.
CASE SUMMARY A 42-year-old human immunodeficiency virus negative male immigrant from Honduras presented to the emergency department of our facility in Louisiana with a 2-mo history of a left lower extremity ulcer. It started as a painless blister that progressed in size and developed into other smaller lesions tracking up the thigh and became tender and erythematous. Clinically looked nontoxic and healthy. He was afebrile. Blood tests, except inflammatory markers, were within normal limits. The cellulitis of the leg was treated with 6 d of vancomycin that also relieved the pain. Skin biopsy was obtained, and histopathology was suspicious for leishmania. Polymerase chain reaction/deoxyribonucleic acid sequencing done by centers for disease control and prevention confirmed the diagnosis as Leishmania panamensis. There was no involvement of naso-oropharyngeal mucosa, confirmed by otolaryngology. The patient was treated with miltefosine for 28 d. Clinic follow-up after approximately 11 mo revealed a healed skin ulcer.
CONCLUSION Cutaneous leishmaniasis should be in the differential diagnosis of skin ulcers of travelers from endemic areas. Awareness regarding diagnosis and treatment of leishmaniasis needs to be enhanced.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). This disease was declared a worldwide health problem with the characteristics of a pandemic. Most patients have mild symptoms and a good prognosis. Information on the evolution and prognosis of COVID-19 in solid organ recipients is scarce.
CASE SUMMARY We describe two patients who underwent liver transplantation with a positive test result for detection of the viral sequence for COVID-19, using reverse-transcription polymerase chain reaction (RT-PCR), immediately before transplantation. The patients showed good evolution in the postoperative period, without signs of graft dysfunction. The immunosuppressive therapy was not modified. Both patients were discharged for subsequent outpatient follow-up.
CONCLUSION In conclusion, it is expected that the experience at this center can be used as an example, aimed at the continuation of transplantations by other services and, thus, the morbidity and mortality of patients with liver disease on the transplantation waiting list can be reduced. Transplant centers must be able to readjust daily to the evolution of the COVID-19 pandemic.

Abstract
Viral infectious diseases have become an increased public health issue in the past 20 years. The outbreaks of severe acute respiratory syndrome coronavirus (SARS-CoV-1) in 2002, influenza H1N1 in 2009, Middle East respiratory syndrome-CoV in 2012, and the current new coronavirus SARS-CoV-2 have shown that viral infectious diseases are a major concern in the 21st century. As the world lives under the pandemic of a new coronavirus (COVID-19), knowing the clinical characteristics from those past diseases and their long-term outcomes is important to understand the current coronavirus pandemic and its complications and consequences better and plan for possible future outbreaks. Several long-term complications have been described with these respiratory viral diseases, such as decreased pulmonary function, pulmonary fibrosis, chronic fatigue syndrome, avascular necrosis of bone, polyneuropathy, encephalitis, posttraumatic stress disorder, depression, and anxiety. This article summarizes several studies describing chronic complications and long-term outcomes of patients recovered from these viral syndromes.

Abstract
BACKGROUND Stenotrophomonas maltophilia (S. maltophilia) is a rare cause of neonatal sepsis with significant morbidity and mortality and has extensive resistance to several antibiotics leaving few options for antimicrobial therapy. Only a few cases have been reported in neonates from developing countries. We report three cases of critically ill, extramural babies with neonatal S. maltophilia sepsis. All three babies recovered and were discharged.
CASE SUMMARY All three cases were term extramural babies, who were critically ill at the time of presentation at our neonatal intensive care unit. They had features of multiorgan dysfunction at admission. Blood culture was positive for S. maltophilia in two babies and one had a positive tracheal aspirate culture. The babies were treated according to the antibiogram available. They recovered and were subsequently discharged.
CONCLUSION Although various authors have reported S. maltophilia in pediatric and adult populations, only a few cases have been reported in the newborn period and this infection is even rarer in developing countries. Although S. maltophilia infection has a grave outcome, our three babies were successfully treated and subsequently discharged.

Abstract
The current corona-2 pandemic has stimulated wide research for hydroxychloroquine (Quine) therapy and lately, prophylaxis. To optimize prophylaxis proper methods of use are explained. The focus is on tools of assessment and robust comparison; defining infection objectively; loading and maintenance dose designing based on pharmaco-viro-kinetics; confirming Quine threshold-levels and its sufficiency; and Quine side-effects vigilance/ amelioration. Attention to statistics to study valid endpoints of goals in appropriately-sized population is essential. Mass interactive quine dose auto designer software is built to simplify, optimize and help collaboration of complex Quine dosing system. A similar chloroquine software can be built.
