ABSTRACT

Importance: Since February 2020, coronavirus disease 2019 (COVID-19) has spread rapidly all over the world, with an epidemiological cluster in Lombardy, Italy. The viral communicability may be mediated by various body fluids, but insufficient information is available on the presence of the virus in human tears. Objectives: To investigate the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in tears collected from patients with COVID-19 by means of real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) assay and to assess the association of virus presence with concomitant clinical conditions. Design, Setting, and Participants: Cross-sectional study conducted between April 9 and May 5, 2020. The setting was intensive care units at Azienda Socio-Sanitaria Territoriale (ASST) Sette-Laghi Hospital, University of Insubria, in Varese, Lombardy, Italy. A conjunctival swab was performed in 91 patients hospitalized for COVID-19, which was clinically diagnosed by rRT-PCR assay on nasopharyngeal swabs and by radiological imaging. Conjunctival swabs from 17 additional healthy volunteer participants with no symptoms of COVID-19 were examined to evaluate the availability and applicability of the conjunctival swab test. Exposure: SARS-CoV-2 detection by means of rRT-PCR assay performed on the collected samples obtained by conjunctival swabs. Main Outcomes and Measures: Conjunctival swab and nasopharyngeal swab results are reported, as well as demographic and clinical data. Results: A total of 108 participants (mean [SD] age, 58.7 [14.2] years; 55 female and 53 male) were tested for SARS-CoV-2 using rRT-PCR assay, including 91 patients hospitalized with COVID-19 and 17 were healthy volunteers. SARS-CoV-2 was found on the ocular surface in 52 of 91 patients with COVID-19 (57.1%; 95% CI, 46.3%-67.5%), with a wide variability in the mean viral load from both eyes. Among a subset of 41 patients, concordance of 63.0% (95% CI, 41.0%-81.0%) was found between positive conjunctival and nasopharyngeal swab test results when performed within 2 days of each other. In 17 of these patients, nasopharyngeal swab results were negative for SARS-CoV-2. In 10 of these 17 patients, conjunctival swab results were positive for the virus. Conclusions and Relevance: In this study, SARS-CoV-2 RNA was found on the ocular surface in a large part of this cohort of patients with COVID-19, although the infectivity of this material could not be determined. Because patients may have positive test results with a conjunctival swab and negative results with a nasopharyngeal swab, use of the slightly invasive conjunctival swab may be considered as a supplementary diagnostic test.

ABSTRACT

The aim of this paper is to analyze an Intensive Care Unit case that required ethics consultation at a University Hospital in Northern Italy. After the case was resolved, a retrospective ethical analysis was performed by four clinical ethicists who work in different healthcare contexts (Italy, the United States, and Switzerland). Each ethicist used a different method to analyze the case; the four general approaches provide insight into how these ethicists conduct ethics consultations at their respective hospitals. Concluding remarks examine the similarities and differences among the various approaches and offer a reflection concerning the possibility of a shared resolution to the case. The authors' efforts to come to a tentative consensus may serve as an example for professionals working in medical contexts that reflect an increasing pluralism of values. This article aims to respond to some of these concerns by illustrating how different methods in clinical ethics would be used when considering a real case. The goal is not to establish the best model (if there is one) on a theoretical level, but to learn from actual practice in order to see if there are common elements in the different methods, and to validate their pertinence to clinical ethics consultation.

ABSTRACT

A 39-year-old Ethiopian HIV-positive man with peripheral T-cell lymphoma developed Strongyloides stercoralis hyperinfection. The patient was initially treated with oral ivermectin for three weeks without response, most likely due to malabsorption because of concomitant paralytic ileus. Given the persistence of larvae in the body fluids, the worsening respiratory status and clinical malabsorption, veterinary parenteral formulation of ivermectin was administered. The very high plasma concentration of ivermectin achieved in the patient after parenteral administration led to a rapid improvement in his clinical condition and rapid disappearance of the parasite from biological samples, without any adverse reaction.

ABSTRACT

BACKGROUND: Medical Emergency Teams (METs) are frequently involved in ethical issues associated to in-hospital emergencies, like decisions about end-of-life care and intensive care unit (ICU) admission. MET involvement offers both advantages and disadvantages, especially when an immediate decision must be made. We performed a survey among Italian intensivists/anesthesiologists evaluating MET's perspective on the most relevant ethical aspects faced in daily practice. METHODS: A questionnaire was developed on behalf of the Italian scientific society of anesthesia and intensive care (SIAARTI) and administered to its members. Decision making criteria applied by respondents when dealing with ethical aspects, the estimated incidence of conflicts due to ethical issues and the impact on the respondents' emotional and moral distress were explored. RESULTS: The questionnaire was completed by 327 intensivists/anesthesiologists. Patient life-expectancy, wishes, and the quality of life were the factors most considered for decisions. Conflicts with ward physicians were reported by most respondents; disagreement on appropriateness of ICU admission and family unpreparedness to the imminent patient death were the most frequent reasons. Half of respondents considered that in case of conflicts the final decision should be made by the MET. Conflicts were generally recognized as causing increased and moral distress within the MET members. Few respondents reported that dedicated protocols or training were locally available. CONCLUSION: Italian intensivists/anesthesiologists reported that ethical issues associated with in-hospital emergencies are occurring commonly and are having a significant negative impact on MET well-being. Conflicts with ward physicians happen frequently. They also conveyed that hospitals don't offer ethics training and have no protocols in place to address ethical issues.

ABSTRACT

Multidrug-resistant (MDR) Klebsiella pneumoniae is one of the most important causes of nosocomial infections worldwide. After the spread of strains resistant to beta-lactams at the end of the previous century, the diffusion of isolates resistant to carbapenems and colistin is now reducing treatment options and the containment of infections. Carbapenem-resistant K. pneumoniae strains have spread rapidly among Italian hospitals, with four subclades of pandemic clonal group 258 (CG258). Here we show that a single Italian hospital has been invaded by three of these subclades within 27 months, thus replicating on a small scale the "Italian scenario." We identified a single clone responsible for an epidemic outbreak involving seven patients, and we reconstructed its star-like pattern of diffusion within the intensive care unit. This epidemiological picture was obtained through phylogenomic analysis of 16 carbapenem-resistant K. pneumoniae isolates collected in the hospital during a 27-month period, which were added to a database of 319 genomes representing the available global diversity of K. pneumoniae strains. Phenotypic and molecular assays did not reveal virulence or resistance determinants specific for the outbreak isolates. Other factors, rather than selective advantages, might have caused the outbreak. Finally, analyses allowed us to identify a major subclade of CG258 composed of strains bearing the yersiniabactin virulence factor. Our work demonstrates how the use of combined phenotypic, molecular, and whole-genome sequencing techniques can help to identify quickly and to characterize accurately the spread of MDR pathogens.

ABSTRACT

BACKGROUND: No conclusive results on the efficacy and timing of open abdomen (OA) are available, particularly in the setting of intra-abdominal infections. We analyzed outcomes and risk factors retrospectively in a large series of patients managed with an OA during the past 20 y in an effort to clarify this issue. METHODS: We reviewed the records of 133 patients who underwent treatment with an OA, considering factors related to patient, disease, medical management, and surgical treatment. The end points of the bi-variable analysis were 1-y mortality, calculated from the time of an initial OA procedure, and definitive fascial closure. RESULTS: Most patients (112/133) managed with an OA had one of several types of peritonitis. Many patients had severe clinical conditions (mean Acute Physiology and Chronic Health Evaluation [APACHE] II score was almost 9 points for the study population). With regard to surgical management, the mean (+SD) number of abdominal revisions was 5.9+9.3 during a mean duration of treatment with an OA of 14.3+11.6 d. The overall mortality in the study was 26% (35/133). Bi-variable analysis revealed factors associated with overall mortality to be age, renal and respiratory co-morbidities, edema on an initial chest radiograph, blood pressure, blood glucose and creatinine concentrations; and APACHE II score. The rate of definitive fascial closure was 75% (100/133). Factors associated negatively with fascial closure were respiratory co-morbidity, edema on a first chest radiograph, post-operative mesenteric ischemia as an indication for OA, blood glucose and creatinine concentrations, and duration of an OA. CONCLUSIONS: Patients' pre-operative clinical status influences strongly their response to surgical treatment. The management of OA does not affect adversely the survival of patients with intra-abdominal infections, but factors related to the management of OA (duration of OA) seem to affect the possibility of definitive fascial closure.

ABSTRACT

BACKGROUND: Vacuum-assisted fascial closure (VAFC-KCI(®)) of an open abdomen is one of the latest methods. METHODS: A prospective observational study was performed with medical records of nine patients who had been treated by abdominal VAFC-KCI(®) from March 2006 to October 2007 in the Department of Surgical Sciences, University of Insubria. The mean Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores were 22.62 and 10.62, respectively. All patients had abdominal compartment syndrome and a sepsis source that was difficult to control. RESULTS: All patients survived. The mean duration of open abdomen was 22.7 days (range, 3-50 days). Primary fascial closure was possible in six patients (66%), with a closure rate of 100% when early control of the infectious source was possible (Group A) but only 40% in patients with difficult and delayed control of infection (Group B). The mean durations of open abdomen in the two groups were statistically different: 8.5 days for Group A vs. 34.2 days for Group B (p < 0.005; Student t-test). CONCLUSIONS: In our brief experience, VAFC-KCI(®) seems to be associated with a high fascial closure rate. The complexity of the management of abdominal source control has a role in the success of primary fascial closure. The VAFC-KCI(®) system seems to contribute positively in fascia-to-fascia abdominal closure in cases of severe abdominal infection, in particular when early surgical source control is obtained.

ABSTRACT

OBJECT: The authors evaluated long-term clinical outcomes in selected acutely comatose patients with severe diffuse brain swelling and recent clinical signs of impending brain death who received a novel high-dose mannitol treatment compared with those who received conventional-dose mannitol in the emergency room. METHODS: Forty-four adult patients with traumatic, nonmissile-inflicted, acute, severe diffuse brain swelling were prospectively and randomly evaluated. All patients were selected based on the presence of recent clinical signs of impending brain death on the first emergency room evaluation. These signs included bilateral abnormal pupillary widening and lack of motor responses to painful stimulation (Glasgow Coma Scale score of 3). The study group (23 patients) received ultra-early and fast intravenous high-dose mannitol treatment (approximately 1.4 g/kg), whereas the control group (21 patients) received half that dose (approximately 0.7 g/kg). Ultra-early improvement of bilateral abnormal pupillary widening was significantly more frequent in the high-dose mannitol group than in the conventional-dose group (p < 0.02). High-dose mannitol treatment in the emergency room was also associated with significantly better 6-month clinical outcomes (p < 0.02); the best rate of favorable outcomes was 43.5%, compared with only 9.5% in the conventional-dose mannitol group. The two groups of patients were well matched with respect to all emergency room and head computerized tomography findings, as well as the timing of initial mannitol treatment (approximately 80-90 minutes after the first evaluation at the scene of the injury). Comparative evaluation of bilateral pupillary widening between the scene of the injury and the emergency room showed no significant differences between groups, whereas mannitol dose dependence was statistically significant (p < 0.05), insofar as early pupillary improvement in the emergency room was concerned. CONCLUSIONS: Ultra-early high-dose mannitol administration in the emergency room is the first known treatment strategy significantly to reverse recent clinical signs of impending brain death, and also to contribute directly to improved long-term clinical outcomes for these patients who have previously been considered unsalvageable.

ABSTRACT

OBJECTIVE: We evaluated long-term clinical outcomes and postoperative physiological findings in acutely comatose patients with nonmissile surgical intraparenchymal temporal lobe hemorrhages and abnormal pupillary widening who received early preoperative high-dose mannitol (HDM) versus conventional dose mannitol treatment in the emergency room. METHODS: One hundred forty-one adult patients with traumatic, nonmissile, acute, intraparenchymal temporal lobe hemorrhages associated with early abnormal pupillary widening were prospectively and randomly assigned to receive emergency preoperative intravenous HDM treatment (approximately 1.4 g/kg; 72 patients) and were compared with a control group that was treated with a lower preoperative mannitol dose (approximately 0.7 g/kg; 69 patients). RESULTS: Early preoperative improvement of abnormal bilateral pupillary widening was significantly more frequent in the study group than in the control group (P < 0.03). The same was true for abnormal unilateral pupillary widening (P < 0.01). Early HDM treatment in the emergency room was also associated with significantly better 6-month clinical outcomes (P < 0.005). The two groups of patients were well matched with respect to diameter of the temporal lobe hemorrhages (approximately 4 cm) as well as timing of clot removal (approximately 2.5 hours after injury). Postoperative physiological findings revealed statistically significant between-group differences, with higher intracranial pressure and lower cerebral extraction of oxygen (global relative cerebral hyperperfusion) in the control group than in the HDM group. Postoperative global brain ischemia (abnormally low arteriojugular lactate difference values) was rare and was found for less than 3% of the patients in both groups. CONCLUSION: Early preoperative HDM administration in the emergency room was associated with improved clinical outcomes for adult comatose patients with acute, nonmissile, intraparenchymal temporal lobe hemorrhages and associated abnormal pupillary widening. Early improvement of bilateral or unilateral pupillary abnormalities and better postoperative control of intracranial hypertension and associated global relative cerebral hyperperfusion seemed to be relevant factors that were related to improved outcomes.
