First Cases of Candida auris in a Referral Intensive Care Unit in Piedmont Region, Italy.

Candida auris is an emerging healthcare-associated infection that can easily cause dissemination in hospitals through colonizing the skin and contaminating environmental surfaces, especially in Intensive Care Units (ICU). Difficulties with identification of this organism, uncertainty about routes of transmission and antifungals resistance have impacted significantly outbreak detection and management. Here, we describe our experience with colonization/infection of C. auris among critically ill patients, admitted to a referral ICU of a University Hospital, in a transitional period (July 2021–March 2022) between management of non-COVID-19 and COVID-19 patients due to the reconversion of the ICU between two waves. A total of 8 patients presented colonization from C. auris, and two of them developed invasive infection from C. auris. The fungal pathogen was cultured from different sites: the skin (7 isolates), urine (2), respiratory tract (1), blood (1). The median time from admission to first detection is 24 days with 100% of patients requiring mechanical ventilation. All 8 patients received broad-spectrum antibiotic therapy for bacterial infections before identification of C. auris; 62.5% of the patients had prior antifungal exposure; 87.5% received steroids; 37.5% patients used immunomodulatory; and 75% had severe COVID-19 illness prior to C. auris identification. Only two cases (25%) were treated with antifungals as C. auris infections (1 patient for suspected UTI; 1 patient with candidemia). Infection control measures, including rapid microbiological identification, contact isolation, screening of contacts, antisepsis of colonized patients, dedicated equipment, cleaning and disinfection of the environment and subsequent follow-up sampling, remain essential in critically ill patients. Our experience highlights the importance of establishing a multidisciplinary model and bundling of practices for preventing C. auris’ spread.

Thrombophlébites pelviennes du post-partum : diagnostic, traitement et suivi. Etude rétrospective sur 10 ans

IntroductionPostpartum ovarian vein thrombosis (POVT) is a rare but serious postpartum complication that can be life-threatening due to its embolic and septic risks. The clinical and paraclinical diagnosis is difficult because of the non-specific signs and the absence of a gold standard for imaging. There is no consensus in the literature on the treatment and follow-up of these patients. The primary objective was to specify the clinical and paraclinical signs suggestive of POVT in order to improve the diagnostic delay. The secondary objectives were to describe the extent of POVT and the proposed immediate therapeutic management. MethodsThis was a 10-year retrospective study in a type III maternity hospital, from January 2010 to December 2019, where all patients with an imaging-confirmed diagnosis of POVT were included. We analysed the clinical and paraclinical data and the follow-up of the patients. ResultsWe included 9 patients with a diagnostic confirmation by imaging. The mean time from first symptoms to diagnosis was 3.3 days (±3.5 days), and only 2 patients (22.2 %) had been diagnosed with POVT before imaging. All patients received curative anticoagulation and 77.8 % (n=7) received antibiotic therapy for POVT. Two patients had a complicated form, 1 with a pulmonary embolism and 1 with a urinary tract compression requiring a urinary diversion with a double J catheter. Five patients (55.6 %) had a thrombophilia check-up. ConclusionThe diagnosis of POVT is difficult and needs to be evoked in front of a painful symptomatology or a fever in postpartum. It can be made by ultrasound, but the injected CT scan specifying the specific search for a POVT remains the imaging examination of choice in order to confirm the diagnosis and eliminate differential diagnoses. Under curative anticoagulation and broad-spectrum antibiotic therapy, the clinical course is generally very favourable. A consultation with an internist makes it possible to define instructions for a subsequent pregnancy.

Management of Fournier’s gangrene during the Covid-19 pandemic era: make a virtue out of necessity

BackgroundFournier’s gangrene (FG) is a necrotizing fasciitis caused by aerobic and anaerobic bacterial infection that involves genitalia and perineum. Males, in their 60 s, are more affected with 1.6 new cases/100.000/year. Main risk factors are diabetes, malignancy, inflammatory bowel disease. FG is a potentially lethal disease with a rapid and progressive involvement of subcutaneous and fascial plane. A multimodal approach with surgical debridement, antibiotic therapy, intensive support care, and hyperbaric oxygen therapy (HBOT) is often needed.We present the inpatient management of an FG case during the Covid-19 pandemic period. A narrative review of the Literature searching “Fournier’s gangrene”, “necrotizing fasciitis” on PubMed and Scopus was performed.Case presentationA 60 years old man affected by diabetes mellitus, with ileostomy after colectomy for ulcerative colitis, was admitted to our Emergency Department with fever and acute pain, edema, dyschromia of right hemiscrotum, penis, and perineal region. Computed tomography revealed air-gas content and fluid-edematous thickening of these regions. Fournier’s Gangrene Severity Index was 9. A prompt broad-spectrum antibiotic therapy with Piperacillin/Tazobactam, Imipenem and Daptomycin, surgical debridement of genitalia and perineal region with vital tissue exposure, were performed. Bedside daily surgical wound medications with fibrine debridement, normal saline and povidone-iodine solutions irrigation, iodoform and fatty gauze application, were performed until discharge on the 40th postoperative day. Every 3 days office-based medication with silver dressing, after normal saline and povidone-iodine irrigation and fibrinous tissue debridement, was performed until complete re-epithelialization of the scrotum on the 60th postoperative day.ConclusionsFG is burdened by a high mortality rate, up to 30%. In the literature, HBOT could improve wound restoration and disease-specific survival. Unfortunately, in our center, we do not have HBOT. Moreover, one of the pandemic period problems was the patient’s displacement and outpatient hospital management. For all these reasons we decided for a conservative inpatient management. Daily cleaning of the surgical wound allowed to obtain its complete restoration avoiding surgical graft and hyperbaric oxygen chamber therapy, without foregoing optimal outcomes.

Necrotizing Fasciitis: Evaluation of 85 Cases and Usage of LRINEC Score.

The present study aims to define the characteristics of the necrotizing fasciitis (NF) cases followed at our hospital and to compare our results with the literature. In this study, NF cases followed and treated at our hospital from January 2005 to April 2019 were evaluated retrospectively. A total of 85 cases of NF were included in the study. Of the cases, 33 (39%) were female and the median age was 59.8±13.1 years (range: 26-92 years). Diabetes mellitus (DM) (56%) was the most prevalent comorbid condition. Extremities were the most frequently involved field found in 41 (48%) of the cases followed by Fournier's gangrene found in 34 (40%) of the cases. All of the cases had undergone surgical intervention (debridement and/or amputation) and received broad-spectrum antibiotic therapy. Laboratory risk indicator for necrotizing fasciitis (LRINEC) score was calculated for 60 cases, and it was 6 or higher in 78% of them. Nineteen (22%) of 85 cases had died. Necrotizing fasciitis affects generally older male patients with DM. In NF cases to avoid the higher risk of mortality, the removal of necrotic tissue via surgical procedure together with antimicrobial therapy is required urgently; therefore, it is very important to differentiate NF from soft tissue infections as soon as possible. As the LRINEC score predicted NF among nearly 80% of our patients, this score could be used as an early diagnostic tool of NF. Level IV, case series.

Necrotizing fasciitis: a severe complication of odontogenic infection

Necrotizing fasciitis is a rare complication of dental infection and is associated with a significant mortality rate. Prompt recognition and urgent referral are therefore essential. Surgical debridement and broad-spectrum intravenous antibiotic therapy are the mainstay of management. This report outlines a case of necrotizing fasciitis of odontogenic origin in an otherwise healthy 32-year-old patient. CPD/Clinical Relevance: This article highlights odontogenic necrotizing fasciitis to the dental team, discusses its management and serves as a reminder of the potential severe complications of unmanaged dental infection.

Non-Coding RNA Networks as Potential Novel Biomarker and Therapeutic Target for Sepsis and Sepsis-Related Multi-Organ Failure.

According to “Sepsis-3” consensus, sepsis is a life-threatening clinical syndrome caused by a dysregulated inflammatory host response to infection. A rapid identification of sepsis is mandatory, as the extent of the organ damage triggered by both the pathogen itself and the host’s immune response could abruptly evolve to multiple organ failure and ultimately lead to the death of the patient. The most commonly used therapeutic strategy is to provide hemodynamic and global support to the patient and to rapidly initiate broad-spectrum empiric antibiotic therapy. To date, there is no gold standard diagnostic test that can ascertain the diagnosis of sepsis. Therefore, once sepsis is suspected, the presence of organ dysfunction can be assessed using the Sepsis-related Organ Failure Assessment (SOFA) score, although the diagnosis continues to depend primarily on clinical judgment. Clinicians can now rely on several serum biomarkers for the diagnosis of sepsis (e.g., procalcitonin), and promising new biomarkers have been evaluated, e.g., presepsin and adrenomedullin, although their clinical relevance in the hospital setting is still under discussion. Non-codingRNA, including long non-codingRNAs (lncRNAs), circularRNAs (circRNAs) and microRNAs (miRNAs), take part in a complex chain of events playing a pivotal role in several important regulatory processes in humans. In this narrative review we summarize and then analyze the function of circRNAs-miRNA-mRNA networks as putative novel biomarkers and therapeutic targets for sepsis, focusing only on data collected in clinical settings in humans.

Panorama of Bacterial Infections Caused by Epidemic Resistant Strains.

Antimicrobial resistance (AMR) represents a critical obstacle to public health worldwide, due to the high incidence of strains resistant to available antibiotic therapies. In recent years, there has been a significant increase in the prevalence of resistant epidemic strains, associated with this, public health authorities have been alarmed about a possible scenario of uncontrolled dissemination of these microorganisms and the difficulty in interrupting their transmission, as nosocomial pathogens with resistance profiles previously considered sporadic. They become frequent bacteria in the community. In addition, therapy for infections caused by these pathogens is based on broad-spectrum antibiotic therapy, which favors an increase in the tolerance of remaining bacterial cells and is commonly associated with a poor prognosis. In this review, we present the current status of epidemic strains of methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), MDR Mycobacterium tuberculosis, extended-spectrum β-lactamase-producing Enterobacterales (ESBL), Klebsiella pneumoniae carbapenemase (KPC), and—New Delhi Metallo-beta-lactamase-producing Pseudomonas aeruginosa (NDM).

Comparison of the effectiveness of savlon antiseptic with povidone-iodine for acinetobacter baumannii infected wounds in white rats (Rattus Norvegicus)

Wound washing with antiseptic liquid is one step in the management of chronic wounds. In infected wounds, washing with antiseptic is expected to reduce bacterial colonies and help eradicate infection. One of the important pathogenic bacteria is Acinetobacter Baumannii. These opportunistic germs can form colonies, especially in patients receiving broad-spectrum antibiotic therapy, treatment in the ICU, and on skin affected by burns. Antiseptic commonly used to wash wound are Savlon and Povidone-iodine 10%. Both antiseptic are broad spectrum antisepctic, kill gram negative and gram positive bacteria. However Savlon could caused skin irritation. Therefore dilution is needed to prevent this effect. This study was intended to determine the difference and comparison of the effectiveness of Savlon and Povidone iodine antiseptic to bacterial growth on wound infected by Acinetobacter Baumannii. This study is an experimental study with a randomized controlled trial without blinding. The wound research procedure was made on the right and left sides of the rat's back with a size of 1x1 cm each. Wounds that have been contaminated with Acinetobacter Baumannii are left for 4 hours. After 4 hours the wound will be washed and irrigated. The wound that has been made is closed with a transparent dressing.

Positivity Trends of Bacterial Cultures from Cases of Acute and Chronic Periprosthetic Joint Infections.

Background: There is no clear distinction in the literature regarding the positivity trends of bacterial cultures in acute and chronic prosthetic joint infections. Methods: We prospectively included in this study all consecutive patients, aged over 18 years, that were hospitalized from September 2016 through December 2019, that underwent a joint arthroplasty revision surgery. Results: Forty patients were included in our analysis, 11 acute/acute hematogenous and 29 chronic PJIs. We were able to identify all strains of acute/acute hematogenous PJIs within 3 days, whereas this took 8 days for chronic PJIs. Sonication fluid cultures increased the positivity rate and helped in identifying rare pathogens such as Ralstonia pickettii from chronic PJIs, but also increased the number of identified strains from acute PJIs. Culturing synovial fluid in our study did not seem to have a clear benefit compared to sonication fluid and periprosthetic tissue cultures. Conclusion: There was a different positivity trend in bacterial cultures. Empiric broad-spectrum antibiotic therapy can be re-evaluated after 3 days for acute PJIs. A prolonged incubation time, especially in the case of chronic PJIs, is mandatory; however, extending the incubation period beyond 14 days would not further improve the ability to identify microorganisms.

Rethinking the “Pan-Culture”: Clinical Impact of Respiratory Culturing in Patients With Low Pretest Probability of Ventilator-Associated Pneumonia

BackgroundRespiratory cultures are often obtained as part of a “pan-culture” in mechanically ventilated patients in response to new fevers or leukocytosis, despite an absence of clinical or radiographic evidence suggestive of pneumonia.MethodsThis was a propensity score–stratified cohort study of hospitalized mechanically ventilated adult patients between 2014 and 2019, with a new abnormal temperature or serum white blood cell count (NATW), but without radiographic evidence of pneumonia, change in ventilator requirements, or documentation of purulent secretions. Two patient groups were compared: those with respiratory cultures performed within 36 hours after NATW and those without respiratory cultures performed. The co-primary outcomes were the proportion of patients receiving >2 days of total antibiotic therapy and >2 days of broad-spectrum antibiotic therapy within 1 week after NATW.ResultsOf 534 included patients, 113 (21.2%) had respiratory cultures obtained and 421 (78.8%) did not. Patients with respiratory cultures performed were significantly more likely to receive antibiotics for >2 days within 1 week after NATW than those without respiratory cultures performed (total antibiotic: adjusted odds ratio [OR], 2.57; 95% CI, 1.39–4.75; broad-spectrum antibiotic: adjusted OR, 2.47, 95% CI, 1.46–4.20).ConclusionsPerformance of respiratory cultures for fever/leukocytosis in mechanically ventilated patients without increasing ventilator requirements, secretion burden, or radiographic evidence of pneumonia was associated with increased antibiotic use within 1 week after incident abnormal temperature and/or white blood cell count. Diagnostic stewardship interventions targeting performance of unnecessary respiratory cultures in mechanically ventilated patients may reduce antibiotic overuse within intensive care units.

Necrotizing fasciitis of the neck: A rare diagnostic emergency

A 76-year-old male, with no prior medical history, was referred to our hospital due to odynophagia and fever with 3 days, sudden worsening with dyspnea, drooling, edema and anterior neck pain. Physical examination revealed tachypnea, trismus, halitosis, bulging of the pharyngeal lateral walls and salivary stasis. No evidence of peritonsillar abscess or tonsil exudate was observed. Contrast-enhanced computed tomography (CT) of the neck revealed an organized collection involving both parapharyngeal and retropharyngeal with air bubbles and edema of the surrounding tissues (Figure 1). The patient was immediately admitted, started empiric broad-spectrum antibiotic therapy and submitted to an emergent surgical drainage. After securing the airway with tracheotomy, a trans-cervical drainage was performed. The drained pus had a grayish color and a foul smell. Necrotic tissue of fascia and sternocleidomastoid muscle were removed, as much as possible, without compromising vital structures. The cervical spaces were irrigated with a diluted solution of povidone-iodine and hydrogen peroxide. Penrose drains were placed and the skin was “loosely” approximated with minimal sutures. (Figure 2). Microbiology of the pus culture revealed the presence of Streptococcus constellatus, Eikenella corrodens, Prevotella buccae and Parvimonas micra.

Przetoka przedsionkowo-przełykowa – stan kliniczny oraz historia choroby jako klucz do postawienia rozpoznania w badaniu obrazowym

Atrioesophageal fistula is an extremely rare, but a life-threatening complication of percutaneous ablation. With an increasing prevalence of atrial fibrillation and increasing number of percutaneous ablation procedures following it, awareness of catheter ablation complications and their detection should be raised. A 69-year-old male, with history of atrial fibrillation admitted with a suspicion of a stroke. The patient was treated with percutaneous ablation 27 days earlier in a different hospital. On admission, in addition to the neurological symptoms, moderately increased inflammatory markers and a low grade fever were found. During the hospitalisation, a prompt inflammatory markers elevation was observed and the patient’s condition had gradually worsened. Sepsis was diagnosed and a broad spectrum antibiotic therapy was administered. On the 6th day of hospitalisation the patient went into cardiac arrest. Cardiopulmonary resuscitation was successful and return of spontaneous circulation occurred. An electrocardiogram showed changes typical for ST elevation myocardial infarction. Emergent coronary angiogram showed no significant stenosis in any of the coronary arteries. In a follow-up brain NECT air emboli were detected. A chest NECT was performed and revealed free gas within the left atrium and in pericardial cavity, which in juxtaposition with the patient’s medical history suggested presence of an atrioesophageal fistula. Despite all taken measures the patient died. An autopsy confirmed atrioesophageal fistula connecting oesophagus with left atrium. The purpose of this case is to raise awareness of percutaneous ablation complications among both clinicians and radiologists. It emphasizes how crucial precise clinical data and imaging exams are in diagnosing atrioesophageal fistula.

Çocukluk çağında renal apse; 6 yaş kız hasta vaka sunumu

Renal abscesses are rarely seen in the childhood period. Delays in diagnosis may cause kidney loss. The treatment method is still controversial. The patient with a large renal abscess, which we operated on because it did not regress with broad-spectrum antibiotic therapy and was not drained with percutaneous drainage because it was organized, was evaluated in the light of the literature. Keywords: Renal abscess, childhood, open surgery, percutaneous drainage.

Pacient s jaterní cirhózou na interním oddělení, intervence případného abúzu alkoholu

Liver cirrhosis represents a common condition with substantial mortality. Manifestation and progression of ascites, hepatic encephalopathy or gastrointestinal bleeding are among main reasons for hospital admission. Infections represent another specific area in cirrhotic patients. Timely and correct diagnosis and therapy of these conditions are the mainstay of optimal outcome. Manifestation of complications of liver cirrhosis significantly deteriorates prognosis of the patient. Ascites in portal hypertension develops as a result of sodium and consequently water retention. Therapy comprises of restriction of sodium intake, diuretic therapy with combination of spironolactone and furosemide, alternatively large-volume paracentesis. Hepatic encephalopathy comprises a spectrum of neuropsychiatric abnormalities from subtle changes to overt desorientation and asterixis to hepatic coma. Treatment includes correcting of predisposing conditions, administering of non-absorbable disaccharides or rifaximin. The most common cause of bleeding in a cirrhotic patient is oesophageal bleeding. Therapy is complex including hemodynamic stabilisation, antibiotic prophylaxis, vasoactive and endoscopic treatment. Infections are common causes of decompensation and occurrence of complications of advanced chronic liver disease. Their unfavourable outcome is a result of a complex immune disorder in cirrhotic patients. Specific type of infection in cirrhosis is spontaneous bacterial peritonitis, which has to be always excluded with diagnostic paracentesis. The mainstay of successful therapy of infections is timely and vigorous broad spectrum antibiotic therapy which can significantly improve otherwise unfavourable outcome of these patients.

Diagnosis and treatment for emphysematous pyelonephritis: analysis of 14 cases from a single centre

Objective: To examine the modalities of treatment and clinical outcomes of emphysematous pyelonephritis (EPN), in order to improve the survival rate of EPN patients. Methods: Totally 14 patients diagnosed as EPN between October 2011 and November 2020 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this article. Data collection including patient demographics, clinical manifestations, management and clinical outcomes were conducted by retrospective charts review, after receiving the institutional review board's approval. There were 11 females and 3 males with a median age of 59 years (range: 52 to 73 years). The lesions were located on the left side in 10 patients and right side in 4 patients. All the 14 patients suffered from fever, and present with severe sepsis or septic shock. The median time from symptom onset to admission to hospital was 3 days(range: 2 to 5 days). All cases had diabetes mellitus. Escherichia coli was the most common organism been cultured (11 cases), while Klebsiella pneumonia was the second (3 cases). CT scan showed bubbly or located gas in the renal parenchyma in 5 cases and presence of steaky or mottled gas in the renal parenchyma in 9 cases. All patients had been admitted to ICU for anti-septic shock therapy. Three patients had undergone percutaneous catheter drainage along with broad-spectrum antibiotics therapy while 3 patients had immediate nephrectomy, the other 8 cases had a combination of an initial percutaneous catheter drainage and second stage nephrectomy. Results: In this case series, 3 patients were died from EPN while the other 11 were survived. The median ICU stay time was 6 days (range: 3 to 11 days). Of the 3 patients died from EPN, 2 had undergone percutaneous catheter drainage along and 1 had received immediate nephrectomy. Among the 11 patients who were survived, only 1 had received percutaneous catheter drainage while the other 10 received nephrectomy (8 patients had staged nephrectomy). Follow-up was performed 6 months after discharge. Of the 11 surviving patients, 2 were lost to follow-up, and the remaining 9 patients had an creatine level of (118.4±29.4) μmol/L (range: 89 to 176 μmol/L). Conclusions: For patients coupled with diabetes who were initially diagnosed as acute pyelonephritis, the possibility of EPN should be considered when the disease progressed rapidly especially septic shock occurred. On the basis of empirical broad-spectrum antibiotics therapy and standardized anti-septic shock treatment, a combination of an initial percutaneous catheter drainage and second stage nephrectomy could be efficacious.

POS-139 AN ATYPICAL PRESENTATION OF DUAL-POSITIVE ANTI-MYELOPEROXIDASE AND ANTI-GLOMERULAR BASEMENT MEMBRANE ANTIBODIES VASCULITIS WITH PULMONARY-RENAL SYNDROME : A CASE REPORT

Double-positive vasculitis with anti-polynuclear cytoplasm (ANCA) and anti-glomerular basement membrane (GBM) antibodies is a rare entity of systemic vasculitis defined by the presence of ANCA and anti-GBM antibodies. We report a rare case of pulmonary-renal syndrome with atypical clinical presentation. A 52 year-old smoking man with a history of exposure to hydrocarbons and uretheral lithiasis, presented in April 2021 epigastralgia and vomiting. the investigations concluded to H.pylori gastritis and ulcer and he received a quadruple therapy. The kidney function was correct in April 2021. The evolution was marked by the persistence of symptoms and urine output had decreased for a few days. He was found to have renal dysfunction (serum creatinine: 2000 µmol/L). Abdominal CT scan without iodinated contrast injection showed severe hydronephrosis of the right pelvicalyceal system with cortical thinning and dilatation of the right ureter. The two kidneys had regular outlines seat multiple bilateral renal cysts with exophytic development. He had a nephrosomy with secondarily a right double-J stent with slight improvement of renal function. The patient presented then with acute respiratory distress.Testing for COVID-19: PCR and serology were negatives. Chest CT scan showed alveolar syndromeevoking pulmonary overload. No pneumopathy covid was shown. The evolution was marked by the non improvement by depletion and he developed hemoptic sputum and low-abundance epistaxis. The attitude was non-invasive ventilation and broad-spectrum antibiotics therapy. Control chest CT showed emphysematous lung with signs of fibrosis with bilateral subpleural nodules. A rereading of the scanner showed intraalveolar hemorrhage which has regressed on the imaging of the control. Based on these data, pneumo renal syndrome was suspected and a bronchoscopy was performed showing alveolar hemorrhage with 70% siderophageswith Gold score superior to 100. Anti-GBM and p-ANCA and antibodies were positive at a high titer. Electroneuromyogram was without anomaly. Kidney biopsy was not done because of the presence of multiple cysts. The patient received pulse methylprednisone for three days followed by oral prednisone and underwent eleven sessions of plasmapheresis. Intraveinous Cyclophosphamide has been started. He showed remarkable recovery as his lung fields cleared with negativity of GBM antibodies. Kidney function didn't improved and he remained dependent on dialysis. Our observation is exceptional since the clinical and radiological presentation of the patient was not that of a pulmonary-renal syndrome. The elements of this syndrome have in fact been masked by the obstacle on the urinary tract on one hand and the hypothesis of a covid19 pneumonia on the other hand in the face of the epidemiological context. Atypical feature of pulmonary renal syndrome should be kept in mind to avoid diagnostic and treatment delays.

Experience of Rwanda on COVID-19 Case Management: From Uncertainties to the Era of Neutralizing Monoclonal Antibodies.

The management of COVID-19 in Rwanda has been dynamic, and the use of COVID-19 therapeutics has gradually been updated based on scientific discoveries. The treatment for COVID-19 remained patient-centered and entirely state-sponsored during the first and second waves. From the time of identification of the index case in March 2020 up to August 2021, three versions of the clinical management guidelines were developed, with the aim of ensuring that the COVID-19 patients treated in Rwanda were receiving care based on the most recent therapeutic discoveries. As the case load increased and imposed imminent heavy burdens on the healthcare system, a smooth transition was made to enable that the asymptomatic and mild COVID-19 cases could continue to be closely observed and managed while they remained in their homes. The care provided to patients requiring facility-based interventions mainly focused on the provision of anti-inflammatory drugs, anticoagulation, broad-spectrum antibiotic therapy, management of hyperglycemia and the provision of therapeutics with a direct antiviral effect such as favipiravir and neutralizing monoclonal antibodies. The time to viral clearance was observed to be shortest among eligible patients treated with neutralizing monoclonal antibodies (bamlanivimab). Moving forward, as we strive to continue detecting COVID-19 cases as early as possible, and promptly initiate supportive interventions, the use of neutralizing monoclonal antibodies constitutes an attractive and cost-effective therapeutic approach. If this approach is used strategically along with other measures in place (i.e., COVID-19 vaccine roll out, etc.), it will enable us to bring this global battle against the COVID-19 pandemic under full control and with a low case fatality rate.

Risk Factors and Algorithms for the Empirical Treatment of Hospital-Acquired Pneumonia and Ventilator-Associated Pneumonia.

Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) continue to be major concerns for morbidity and mortality, especially in patients treated in the intensive care unit. With the rise in multidrug-resistant organisms, HAP and VAP treatment is challenged by the need for early appropriate treatment, with broad-spectrum agents, while still being aware of the principles of antibiotic stewardship. The two major society guidelines proposed a series of risk factors in their most recent guidelines to help identify patients who can most benefit from narrow- or broad-spectrum initial empiric antibiotic therapy. The guidelines reveal differences in the proposed risk factors and treatment approaches, as well as major similarities.
