The impact of being in the COVID-19 pandemic on in-hospital mortality of non-infected patients aged 80 years and older with ST-elevation myocardial ınfarction

The COVID-19 outbreak in late 2019 was declared a pandemic by the World Health Organization(WHO)on March 12,2020.[1]As of the latest WHO data,COVID-19 has caused over 770 million cases and nearly 7 million deaths worldwide.[2]Hospitalizations due to COVID-19 are correlated with advanced age.[3,4]According to re-ports,individuals over the age of 65 account for 80%of COVID-19-related deaths.[3,4]This is primar-ily due to the increased burden of comorbidity with age.

Infection in Multiple Myeloma: Microbiological Profile and Prognosis in Senegalese Patients

Introduction: Infections are additional factors of morbidity and mortality in multiple myeloma (MM), and the current recommendation is antibiotic prophylaxis. In sub-Saharan Africa, few data on infectious complications of MM are available. We aim to describe the microbiological features of infections in MM, and their impact on survival in Senegalese patients. Methods: A retrospective (January 2005-January 2022), analytic, multicenter study on infections in patients followed for MM (IMWG criteria) in Senegalese clinical hematology services. The socio-epidemiological, diagnostic, microbiological, evolutionary and survival aspects were analyzed. Results: The study included 106 patients with multiple myeloma who had an infection at admission or during the treatment. Ten patients have the comorbidity (hypertension, lupus, type 2 diabetes). These patients had 136 infectious events identified at diagnosis (79.2%) or during chemotherapy (20.8%). The sites of infection are lung (42.6%), urinary (29.4%), dermatological (6.6%), digestive (5.2%), osteoarticular (4.4%), ear, nose and throat (3.7%), central nervous system (1.5%), or without site. We recorded 26.4% of patients with multi-site infections. The causal pathogens are bacteria (Gram-negative bacilli: 22.1%;Gram positive bacilli: 9.5%, Mycobacterium tuberculosis: 13.3%), parasitique (plasmodium falciparum 6.6%), viruses (SARS-COV2: 2.9%, VZV: 2.2%) and fungal (2.9%). Survival was reduced in patients who had an infection at the time of multiple myeloma diagnosis (p: 0.189) and those who had multiple infectious foci (p: 0.011). Conclusion: Infections in multiple myeloma are more frequent at diagnosis. The germs are varied and mostly bacteria, particularly gram-negative bacteria, and Kochs bacillus. Our study reveals that multiple infectious foci are a poor prognosis factor. It is necessary to evaluate the infectious risk early, and to adopt an antibiotic prophylaxis based on our tropical environment.

Plasma Metabonomics of Human Adenovirus-infected Patients with Pneumonia and Upper Respiratory Tract Infection

Objective Human adenovirus(HAdV)infection is common and can develop to serious conditions with high mortality,yet the mechanism of HAdV infection remains unclear.In the present study,the serum metabolite profiles of HAdV-7-infected patients with pneumonia or upper respiratory tract infection(URTI)were explored.Methods In total,35 patients were enrolled in the study following an outbreak of HAdV-7 in the army,of whom 14 had pneumonia and 21 had URTI.Blood samples were collected at the acute stage and at the recovery stage and were analyzed by untargeted metabolomics.Results Over 90% of the differential metabolites identified between the pneumonia patients and URTI patients were lipids and lipid-like molecules,including glycerophospholipids,fatty acyls,and sphingolipids.The metabolic pathways that were significantly enriched were primarily the lipid metabolism pathways,including sphingolipid metabolism,glycerophospholipid metabolism,and linoleic acid metabolism.The sphingolipid metabolism was identified as a significantly differential pathway between the pneumonia patients and URTI patients and between the acute and recovery stages for the pneumonia patients,but not between the acute and recovery stages for the URTI patients.Ceramide and lactosylceramide,involved in sphingolipid metabolism,were significantly higher in the pneumonia patients than in the URTI patients with good discrimination abilities[area under curve(AUC)0.742 and 0.716,respectively;combination AUC 0.801].Conclusion Our results suggested that HAdV modulated lipid metabolism for both the patients with URTI and pneumonia,especially the sphingolipid metabolism involving ceramide and lactosylceramide,which might thus be a potential intervention target in the treatment of HAdV infection.

Current status of liver transplantation for human immunodeficiency virus-infected patients in China's Mainland

According to the report from the Chinese Center for Disease Control and Prevention,the prevalence of human immunodeficiency virus(HIV)infection exceeded 1.2 million individuals by the year 2022,with an annual increase of about 80000 cases.The overall prevalence of hepatitis B surface antigen among individuals co-infected with HIV reached 13.7%,almost twice the rate of the general population in China.In addition to the well-documented susceptibility to opportunistic infections and new malignancies,HIV infected patients frequently experience liver-related organ damage,with the liver and kidneys being the most commonly affected.This often leads to the development of end-stage liver and kidney diseases.Therefore,organ transplantation has emerged as an important part of active treatment for HIV infected patients.However,the curative effect is not satisfactory.HIV infection has been considered a contraindication for organ transplantation.Until the emergence of highly active anti-retroviral therapy in 1996,the once intractable replication of retrovirus was effectively inhibited.With prolonged survival,the failure of important organs has become the main cause of death among HIV patients.Therefore,transplant centers worldwide have resu-med exploration of organ transplantation for HIV-infected individuals and reached a positive conclusion.This study provides an overview of the current landscape of HIV-positive patients receiving liver transplantation(LT)in main-land China.To date,our transplant center has conducted LT for eight end-stage liver disease patients co-infected with HIV,and all but one,who died two months postoperatively due to sepsis and progressive multi-organ failure,have survived.Comparative analysis with hepatitis B virus-infected patients during the same period revealed no statistically significant differences in acute rejection reactions,cytomegalovirus infection,bacteremia,pulmonary infections,acute kidney injury,new-onset cancers,or vascular and biliary complications.

Effect of acacetin on inhibition of apoptosis in Helicobacter pyloriinfected gastric epithelial cell line

BACKGROUND Helicobacter pylori(H.pylori)infection can cause extensive apoptosis of gastric epithelial cells,serving as a critical catalyst in the progression from chronic gastritis,gastrointestinal metaplasia,and atypical gastric hyperplasia to gastric carcinoma.Prompt eradication of H.pylori is paramount for ameliorating the pathophysiological conditions associated with chronic inflammation of the gastric mucosa and the primary prevention of gastric cancer.Acacetin,which has multifaceted pharmacological activities such as anti-cancer,anti-inflammatory,and antioxidative properties,has been extensively investigated across various domains.Nevertheless,the impact and underlying mechanisms of action of acacetin on H.pylori-infected gastric mucosal epithelial cells remain unclear.AIM To explore the defensive effects of acacetin on apoptosis in H.pylori-infected GES-1 cells and to investigate the underlying mechanisms.METHODS GES-1 cells were treated with H.pylori and acacetin in vitro.Cell viability was assessed using the CCK-8 assay,cell mortality rate via lactate dehydrogenase assay,alterations in cell migration and healing capacities through the wound healing assay,rates of apoptosis via flow cytometry and TUNEL staining,and expression levels of apoptosis-associated proteins through western blot analysis.RESULTS H.pylori infection led to decreased GES-1 cell viability,increased cell mortality,suppressed cell migration,increased rate of apoptosis,increased expressions of Bax and cle-caspase3,and decreased Bcl-2 expression.Conversely,acacetin treatment enhanced cell viability,mitigated apoptosis induced by H.pylori infection,and modulated the expression of apoptosis-regulatory proteins by upregulating Bcl-2 and downregulating Bax and cleaved caspase-3.CONCLUSION Acacetin significantly improved GES-1 cell viability and inhibited apoptosis in H.pylori-infected GES-1 cells,thereby exerting a protective effect on gastric mucosal epithelial cells.

Lung imaging characteristics in a patient infected with Elizabethkingia miricola following cerebral hemorrhage surgery: A case report

BACKGROUND Elizabethkingia miricola is a non-fermenting gram-negative bacterium,which was first isolated from the condensate of the Russian peace space station in 2003.Most studies on this bacterium have been carried out in the laboratory,and clinical case studies are rare.To date,a total of 6 clinical cases have been reported worldwide.CASE SUMMARY We present the first case of postoperative pulmonary infection in a patient with intracerebral hemorrhage due to Elizabethkingia miricola.The imaging character-istics of pulmonary infection were identified and the formulation and selection of the clinical treatment plan for this patient are discussed.CONCLUSION Elizabethkingia miricola infection is rare.When pulmonary infection occurs,computed tomography imaging may show diffuse distribution of a ground glass density shadow in both lungs,the air containing bronchial sign in local areas,thickening of bronchial vascular bundle,and pleural effusion.

Early prediction and prevention of infected pancreatic necrosis

Approximately 20%-30%of patients with acute necrotizing pancreatitis develop infected pancreatic necrosis(IPN),a highly morbid and potentially lethal complication.Early identification of patients at high risk of IPN may facilitate appropriate preventive measures to improve clinical outcomes.In the past two decades,several markers and predictive tools have been proposed and evaluated for this purpose.Conventional biomarkers like C-reactive protein,procalcitonin,lymphocyte count,interleukin-6,and interleukin-8,and newly developed biomarkers like angiopoietin-2 all showed significant association with IPN.On the other hand,scoring systems like the Acute Physiology and Chronic Health Evaluation II and Pancreatitis Activity Scoring System have also been tested,and the results showed that they may provide better accuracy.For early prevention of IPN,several new therapies were tested,including early enteral nutrition,anti-biotics,probiotics,immune enhancement,etc.,but the results varied.Taken together,several evidence-supported predictive markers and scoring systems are readily available for predicting IPN.However,effective treatments to reduce the incidence of IPN are still lacking apart from early enteral nutrition.In this editorial,we summarize evidence concerning early prediction and prevention of IPN,providing insights into future practice and study design.A more homo-geneous patient population with reliable risk-stratification tools may help find effective treatments to reduce the risk of IPN,thereby achieving individualized treatment.

Early endoscopic management of an infected acute necrotic collection misdiagnosed as a pancreatic pseudocyst: A case report

BACKGROUND Infected acute necrotic collection(ANC)is a fatal complication of acute pancre-atitis with substantial morbidity and mortality.Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis;however,there is great controversy about the optimal drainage time,and better treatment should be explored.CASE SUMMARY We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancre-atitis;conservative treatment was ineffective,and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography(CT).Endoscopic ultra-sonography(EUS)suggested hyperechoic necrotic tissue within the cyst cavity.The wall was not completely mature,and the culture of the puncture fluid was positive for A-haemolytic Streptococcus.Thus,the final diagnosis of ANC in-fection was made.The necrotic collection was not walled off and contained many solid components;therefore,the patient underwent EUS-guided aspiration and lavage.Two weeks after the collection was completely encapsulated,pancreatic duct stent drainage via endoscopic retrograde cholangiopancreatography(ERCP)was performed,and the patient was subsequently successfully discharged.On repeat CT,the pancreatic cysts had almost disappeared during the 6-month fo-llow-up period after surgery.CONCLUSION Early EUS-guided aspiration and lavage combined with late ERCP catheter drainage may be effective methods for intervention in infected ANCs.

The microbiology of infected pancreatic necrosis

Background: Acute pancreatitis(AP) continues to cause significant morbidity and mortality, especially when it leads to infected pancreatic necrosis(IPN). Modern treatment of IPN frequently involves prolonged courses of antibiotics in combination with minimally invasive therapies. This study aimed to update the existing evidence base by identifying the pathogens causing IPN and therefore aid future selection of empirical antibiotics. Methods: Clinical data, including microbiology results, of consecutive patients with IPN undergoing minimally invasive necrosectomy at our institution between January 2009 and July 2016 were retrospectively reviewed. Results: The results of 40 patients(22 males and 18 females, median age 60 years) with IPN were reviewed. The etiology of AP was gallstones, alcohol, dyslipidemia and unknown in 31, 2, 2 and 5 patients, respectively. The most frequently identified microbes in microbiology cultures were Enterococcus faecalis and faecium(22.5% and 20.0%) and Escherichia coli(20.0%). In 19 cases the cultures grew multiple organisms. The antibiotics with the least resistance amongst the microbiota were teicoplanin(5.0%), linezolid(5.6%), ertapenem(6.5%), and meropenem(7.4%). Conclusion: The carbapenem antibiotics, ertapenem and meropenem provide good antimicrobial cover against the common, mainly enteral, microorganisms causing IPN. Culture and sensitivity results of acquired samples should be regularly reviewed to adjust prescribing and monitor for emergence of resistance.

Factors of Adherence to Concurrent Tuberculosis Treatment and Antiretroviral Therapy among HIV-TB Co-Infected Individuals in the East Region, Cameroon in the COVID-19 Era: A Retrospective Cohort Study

Context/Objectives: Tuberculosis (TB) and HIV co-infection is a serious health problem in Cameroon. The problems associated with poor adherence to treatment are on the increase worldwide. This problem can be observed in all situations where patients are required to administer their own medication, whatever the type of illness. The general objective of this study was to assess the factors affecting adherence to treatment among HIV-TB co-infected patients in health facilities in the East Region in the COVID context. Method: A retrospective cohort study before and during COVID-19 was conducted in HIV care units in 13 health districts in the East Region of Cameroon. Data were collected using a questionnaire recorded in the Kobo Collect android application, analyzed using SPSS version 25 software and plotted using Excel. Results: The pre-COVID-19 cohort compared to the during-COVID-19 cohort had a 1.90 risk of not adhering to treatment (OR: 1.90, CI {1.90 - 3.37}) and the difference was statistically significant at the 5% level (p-value = 0.029). Frequency of adherence was 65.4% (140/214). Adherence before COVID-19 was 56.9% whereas during COVID-19, it was 74.3%. Conclusion: The implementation of targeted interventions in the COVID-19 context, using evidence-based data and integrating the individual needs of HIV-TB co-infected patients, improved adherence to concurrent anti-tuberculosis treatment and antiretroviral therapy during the COVID-19 Era.

Endoscopic transluminal drainage and necrosectomy for infected necrotizing pancreatitis:Progress and challenges

Infected necrotizing pancreatitis(INP)represents a severe condition in patients with acute pancreatitis.Invasive interventions are recommended in symptomatic INP.Growing evidence has suggested interventional strategies of INP evolving from traditional surgery to minimally invasive step-up endoscopic procedures.However,there is still no standardized protocol for endoscopic interventions.Recently,various studies have been published about the endoscopic management of INP.This article reviews published articles and guidelines to present the progress and challenges of endoscopic transluminal drainage and necrosectomy in INP.

Microbiology laboratory and the management of motherchild varicella-zoster virus infection

Varicella-zoster virus, which is responsible for varicella(chickenpox) and herpes zoster(shingles), is ubiquitous and causes an acute infection among children, especially those aged less than six years. As 90% of adults have had varicella in childhood, it is unusual to encounter an infected pregnant woman but, if the disease does appear, it can lead to complications for both the mother and fetus or newborn. The major maternal complications include pneumonia, which can lead to death if not treated. If the virus passes to the fetus, congenital varicella syndrome, neonatal varicella(particularly serious if maternal rash appears in the days immediately before or after childbirth) or herpes zoster in the early years of life may occur depending on the time of infection. A Microbiology laboratory can help in the diagnosis and management of mother-child infection at four main times:(1) when a pregnant woman has been exposed to varicella or herpes zoster, a prompt search for specific antibodies can determine whether she is susceptible to, or protected against infection;(2) when a pregnant woman develops clinical symptoms consistent with varicella, the diagnosis is usually clinical, but a laboratory can be crucial if the symptoms are doubtful or otherwise unclear(atypical patterns in immunocompromised subjects, patients with post-vaccination varicella, or subjects who have received immunoglobulins), or if there is a need for a differential diagnosis between varicella and other types of dermatoses with vesicle formation;(3) when a prenatal diagnosis of uterine infection is required in order to detect cases of congenital varicella syndrome after the onset of varicella in the mother; and(4) when the baby is born and it is necessary to confirm a diagnosis of varicella(and its complications), make a differential diagnosis between varicella and other diseases with similar symptoms, or confirm a causal relationship between maternal varicella and malformations in a newborn.

Timing, distribution, and microbiology of infectious complications after necrotizing pancreatitis

BACKGROUND Acute pancreatitis(AP)is a common acute abdominal disease worldwide,and its incidence rate has increased annually.Approximately 20%of AP patients develop into necrotizing pancreatitis(NP),and 40%to 70%of NP patients have infectious complications,which usually indicate a worse prognosis.Infection is an important sign of complications in NP patients.AIM To investigate the difference in infection time,infection site,and infectious strain in NP patients with infectious complications.METHODS The clinical data of AP patients visiting the Department of General Surgery of Xuanwu Hospital of Capital Medical University from January 1,2014 to December 31,2018 were collected retrospectively.Enhanced computerized tomography or magnetic resonance imaging findings in patients with NP were included in the study.Statistical analysis of infectious bacteria,infection site,and infection time in NP patients with infectious complications was performed,because knowledge about pathogens and their antibiotic susceptibility patterns is essential for selecting an appropriate antibiotic.In addition,the factors that might influence the prognosis of patients were analyzed.RESULTS In this study,539 strains of pathogenic bacteria were isolated from 162 patients with NP infection,including 212 strains from pancreatic infections and 327 strains from extrapancreatic infections.Gram-negative bacteria were the main infectious species,the most common of which were Escherichia coli and Pseudomonas aeruginosa.The extrapancreatic infection time(9.1±8.8 d)was earlier than the pancreatic infection time(13.9±12.3 d).Among NP patients with early extrapancreatic infection(<14 d),bacteremia(25.12%)and respiratory tract infection(21.26%)were predominant.Among NP patients with late extrapancreatic infection(>14 d),bacteremia(15.94%),respiratory tract infection(7.74%),and urinary tract infection(7.71%)were predominant.Drug sensitivity analysis showed that P.aeruginosa was sensitive to enzymatic penicillins,thirdand fourth-generation cephalosporins,and carbapenems.Acinetobacter baumannii and Klebsiella pneumoniae were sensitive only to tigecycline;Staphylococcus epidermidis and Enterococcus faecium were highly sensitive to linezolid,tigecycline,and vancomycin.CONCLUSION In this study,we identified the timing,the common species,and site of infection in patients with NP.

Microbiology and risk factors for gram-positive Cocci bacteremia in biliary infections

Background:The rapid antibiotics treatment targeted to a specific pathogen can improve clinical outcomes of septicemia.We aimed to evaluate the clinical characteristics and outcomes of biliary septicemia caused by cholangitis or cholecystitis according to causative organisms.Methods:We performed a retrospective cohort study in 151 patients diagnosed with cholangitis or cholecystitis with bacterial septicemia from January 2013 to December 2015.All patients showed clinical evidence of biliary tract infection and had blood isolates that demonstrated septicemia.Results:Gram-negative,gram-positive,and both types of bacteria caused 84.1%(127/151),13.2%(20/151),and 2.6%(4/151)episodes of septicemia,respectively.The most common infecting organisms were Escherichia coli among gram-negative bacteria and Enterococcus species(Enterococcus casseliflavus and Enterococcus faecalis)among gram-positive bacteria.There were no differences in mortality,re-admission rate,and need for emergency decompression procedures between the gram-positive and gram-negative septicemia groups.In univariate analysis,previous gastrectomy history was associated with gram-positive bacteremia.Multivariate analysis also showed that previous gastrectomy history was strongly associated with gram-positive septicemia(Odds ratio=5.47,95%CI:1.19–25.23;P=0.029).Conclusions:Previous gastrectomy history was related to biliary septicemia induced by gram-positive organisms.This information would aid the choice of empirical antibiotics.

The Use of Autologous Tibia Strut Graft to Enhance Bone Healing of an Infected Long-Bone Nonunion

We treated five patients with an infected non-union of the femur and tibia with autologous tibia strut grafts. All patients had bone defects ranging from three to nine centimeters. Three patients suffered for more than seven years from chronic osteitis. Our objective was to describe this grafting technique and its results. We focussed on healing time, postoperative complications and functional recovery. We retrospectively studied five patients with an infected non-union of the lower limb who had undergone previous surgeries to overcome the bone healing problem. In this group of patients, we had four femur non-union and one tibia non-union. All of them had a previous infection episode, in which medical and surgical therapy was needed. Of the participants, three were men, and two were females with a mean age of 43.3 years (28 - 55).

Community-acquired multidrug-resistant pneumonia,bacteraemia,and infective endocarditis:A case report

BACKGROUND The prevalence of multidrug-resistant(MDR)bacteria has increased globally,with extensive drug-resistant(XDR)bacteria posing a threat to patients.CASE SUMMARY This case report describes a young man admitted for suspected tropical fever infections who experienced rapid deterioration in health.Despite negative results for tropical fever infections,he had neutrophilic leucocytosis,acute kidney injury,and chest imaging findings suggestive of bilateral consolidations.On day two,he was diagnosed with infective endocarditis with possible rheumatic heart disease and MDR methicillin-resistant Staphylococcus aureus bacteraemia,and communityacquired pneumonia.Despite treatment with broad-spectrum antibiotics,he did not respond and succumbed to death on day five.CONCLUSION This case highlights that clinicians/public should be aware of MDR communityacquired pneumonia,bacteraemia,and endocarditis which ultimately culminate in high rates of morbidity and mortality.Early identification of pathogenic strain and prompt antibiotic treatment are a mainstay for the management and prevention of early fatalities.Simultaneously,route cause analysis of communityacquired MDR/XDR pathogens is a global need.

Cervical Spondylodiscitis Revealed by Tracheostomy Infected: A Rare Case Report Management and Outcome

Background: Spondylodiscitis is a spinal infection rare affecting primarily the intervertebral disk and the adjacent vertebral bodies. His diagnosis is difficult and often delayed or missed due to the rarity of the disease. Cervical spondylodiscitis has quite rare findings regarding the common location of spinal abscesses in the lumbar and thoracic regions. To obtain the best patient outcomes, these spinal infections require prompt diagnosis and appropriate treatment. Case description: A 44-year-old boy was admitted to the neurosurgery department of our hospital for heaviness in 4 limbs without gait disorders in context infected tracheostomy after staying in intensive care. MRI spine showed a spine deformity with lyse C4C5 epiduritis and spinal cord compressed. Antibiotics intravenous were started for 1 month the patient benefited from a corpectomy with an iliac graft and anterior cervical plate. The anatomopathological examination revealed an inflammation not specific. He was therefore put on antibiotics for 6 weeks. Three months later the neck pain and limb pain resolved after treatment and a complete return of lower extremity strength. Conclusion: Cervical spondylodiscitis has increased and become more aggressive. While radical surgical debridement, stable reconstruction together with antibiotic therapy remained a reliable approach to achieve complete healing of the inflammation, anterior alone surgery became more applicable.

Blood Count Abnormalities Associated with Death in Patients Infected with SARS-COV-2 at the Ziguinchor EpidemicTreatment Center (ETC)

Introduction: SARS-COV-2 infection is a real public health challenge for the World Health Organization and for our country. It is responsible for numerous hematological abnormalities in infected patients. Objectives: To describe the haemogram abnormalities in patients infected with SARS-COV-2 and to determine which ones are associated with death. Material and Method: We conducted a retrospective, descriptive, analytical, cross-sectional study from March 2020 to September 2021. The study included all patients hospitalized with RT-PCR-confirmed COVID-19 who performed a blood count. We evaluated the blood count profile, the pathologies found and the associated blood count abnormalities. Results: A total of 263 patients were included. The mean age of the patients was 63.77 years (range 12 - 90 years). The male sex represented 54.75% (n = 144) while the female sex was 45.25% (n = 119) (sex ratio = 1.21). The most common pathologies were: diabetes: 30.03% (n = 79), high blood pressure: 41.04% (n = 108), and Chronic kidney disease: 7.98 (n = 21). The abnormalities of the haemogram found were essential: anaemia 28.13% (n = 121), hyperleukocytosis with neutrophilic predominance: 29.3% (126), lymphopenia: 34.41% (n = 148), thrombocytopenia: 8.16% (n = 35). The search for hematological factors associated with death in patients showed a significant difference between hyperleukocytosis (p = 0.000) and lymphopenia (p = 0.0001). Conclusion: SARS-COV-2 disease was a mortality factor when associated with lymphopenia and hyperleukocytosis in our series.
