Clinical effectiveness of cefiderocol for the treatment of bloodstream infections due to carbapenem-resistant Acinetobacter baumannii during the COVID-19 era: a single center, observational study.

BACKGROUND: We assessed the clinical effectiveness of cefiderocol (CFDC) in comparison with colistin (COL) for the treatment of carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infections (BSI). MATERIALS/METHODS: Retrospective cohort study including adults with CRAB-BSI. Outcomes were mortality, clinical cure and adverse events during therapy. The average treatment effect of CFDC compared to COL was weighted with the inverse-probability treatment weight (IPTW). RESULTS: Overall, 104 patients were included (50 CFDC, 54 COL), median age 66.5 years, median Charlson Comorbidity Index 5, septic shock in 33.6% of patients. Primary BSI accounted for 43.3% of cases, followed by ventilator-associated pneumonia (VAP) (26%), catheter-related BSI (20.2%) and hospital-acquired pneumonia (HAP) (9.6%). Although not significantly, mortality at all time points was lower for CFDC than COL, while clinical cure was higher in CFDC than COL (66% vs. 44.4%, p = 0.027). Adverse events were more frequent in COL than CFDC-group (38.8% vs. 10%, p < 0.0001), primarily attributed to acute kidney injury (AKI) in the COL group. Patients with bacteremic HAP/VAP treated with CFDC had a significant lower 30-d mortality and higher clinical cure than COL (p = 0.008 and p = 0.0008, respectively). Increment of CCI (p = 0.005), ICU (p = 0.025), SARS-CoV2 (p = 0.006) and ECMO (p < 0.0001) were independently associated with 30-d mortality, while receiving CFDC was not associated with survival. CONCLUSIONS: CFDC could represent an effective and safe treatment option for CRAB BSI, especially in patients with bacteremic HAP/VAP and frail patients where the risk of acute renal failure during therapy should be avoided.

Comparison of clinical features and outcomes in COVID-19 and influenza pneumonia patients requiring intensive care unit admission.

BACKGROUND: Little is known in distinguishing clinical features and outcomes between coronavirus disease-19 (COVID-19) and influenza (FLU). MATERIALS/METHODS: Retrospective, single-centre study including patients with COVID-19 or FLU pneumonia admitted to the Intensive care Unit (ICU) of Policlinico Umberto I (Rome). Aims were: (1) to assess clinical features and differences of patients with COVID-19 and FLU, (2) to identify clinical and/or laboratory factors associated with FLU or COVID-19 and (3) to evaluate 30-day mortality, bacterial superinfections, thrombotic events and invasive pulmonary aspergillosis (IPA) in patients with FLU versus COVID-19. RESULTS: Overall, 74 patients were included (19, 25.7%, FLU and 55, 74.3%, COVID-19), median age 67 years (58-76). COVID-19 patients were more male (p = 0.013), with a lower percentage of COPD (Chronic Obstructive Pulmonary Disease) and chronic kidney disease (CKD) (p = 0.001 and p = 0.037, respectively) than FLU. SOFA score was higher (p = 0.020) and lymphocytes were significantly lower in FLU than in COVID-19 [395.5 vs 770.0 cells/mmc, p = 0.005]. At multivariable analysis, male sex (OR 6.1, p < 0.002), age > 65 years (OR 2.4, p = 0.024) and lymphocyte count > 725 cells/mmc at ICU admission (OR 5.1, p = 0.024) were significantly associated with COVID-19, whereas CKD and COPD were associated with FLU (OR 0.1 and OR 0.16, p = 0.020 and p < 0.001, respectively). No differences in mortality, bacterial superinfections and thrombotic events were observed, whereas IPA was mostly associated with FLU (31.5% vs 3.6%, p = 0.0029). CONCLUSIONS: In critically ill patients, male sex, age > 65 years and lymphocytes > 725 cells/mmc are related to COVID-19. FLU is associated with a significantly higher risk of IPA than COVID-19.

Co-infection of SARS-CoV-2 with Chlamydia or Mycoplasma pneumoniae: a case series and review of the literature.

INTRODUCTION: The novel coronavirus SARS-CoV-2 has spread all over the world causing a global pandemic and representing a great medical challenge. Nowadays, there is limited knowledge on the rate of co-infections with other respiratory pathogens, with viral co-infection being the most representative agents. Co-infection with Mycoplasma pneumoniae has been described both in adults and pediatrics whereas only two cases of Chlamydia pneumoniae have been reported in a large US study so far. METHODS: In the present report, we describe a series of seven patients where co-infection with C. pneumoniae (n = 5) or M. pneumoniae (n = 2) and SARS-CoV-2 was detected in a large teaching hospital in Rome. RESULTS AND CONCLUSION: An extensive review of the updated literature regarding the co-infection between SARS-CoV-2 and these atypical pathogens is also performed.

Fashioning enterotomy closure after totally laparoscopic ileocolic anastomosis for right colon cancer: a multicenter experience.

BACKGROUND: Laparoscopic right hemicolectomy is a commonly performed procedure. Little is known on how to perform the enterotomy closure after stapled side-to-side intracorporeal anastomosis. METHOD: A multicentric case-controlled study has been designed to compare different ways to fashion enterotomy closure: double layer versus single layer, sewn versus stapled, and robotic versus laparoscopic approach. Furthermore, additional characteristics including sutures' materials, interrupted versus running suture and the presence of deep corner suture has been investigated. RESULTS: We collected data for 1092 patients who underwent right hemicolectomy at ten centers. We analyzed 176 robotic against 916 laparoscopic anastomosis: no significant differences were found in terms of bleedings (p = 0.455) and anastomotic leak (p = 0.405). We collected data from 126 laparoscopic sewn single-layer versus 641 laparoscopic sewn double-layer anastomosis: a significant reduction was recorded in terms of leaks in double-layer group (p = 0.02). About double-layer characteristics, we found a significant reduction of bleedings (p = 0.008) and leaks (p = 0.017) with a running suture; similarly, a reduction of bleedings (p = 0.001) and leaks (p = 0.005) was observed with the usage of deep corner closure. The presence of a barbed suture thread seemed to significantly reduce both bleedings (p = 0.001) and leaks (p = 0.001). We found no significant differences in terms of bleedings (p = 0.245) and anastomotic leak (p = 0.660) comparing sewn versus stapled anastomosis. CONCLUSIONS: Fashioning a stapled ileocolic intracorporeal anastomosis, we can recommend the adoption of a double-layer enterotomy closure using a running barbed suture in the first layer. Totally, stapled closure and robotic assistance have to be considered a non-inferior alternative.

Preliminary risk assessment of workplace violence in hospital emergency departments.

BACKGROUND: The risk assessment of workplace violence in emergency departments represents a global challenge for both healthcare organizations and workers. Recent studies have revealed increased rates of workplace violence towards physicians and nurses employed in emergency departments and have shown that type II is the most common typology of workplace violence among the four types of workplace violence defined by the National Institute for Occupational Safety and Health. The present study aimed to develop a methodological technique for a preliminary assessment of type II workplace violence risk in emergency departments. METHODS: The Delphi method was used to develop a questionnaire entitled Emergency Department Workplace Violence-Questionnaire which was composed of two sections: 1) sentinel events, and 2) risk factors. The authors used the Emergency Department Workplace Violence-Questionnaire to evaluate the workplace violence risk among physicians and nurses employed in a hospital emergency department. RESULTS: The Emergency Department Workplace Violence-Questionnaire was composed of 21 items. The sentinel events section consisted of three company indicators related to workplace violence and identified three areas of risk. The risk factors section identified 18 organizational and environmental factors associated with workplace violence occurrence. The assessment of workplace violence risk in the targeted hospital emergency departments, obtained through the use of the Emergency Department Workplace Violence-Questionnaire, showed a medium risk of workplace violence for both physicians (score=18) and nurses (score=19.5); the analysis found objective risk factors associated with workplace violence and led us to suggest organizational and environmental interventions for reducing the sources of risk among healthcare workers and to prioritize the interventions targeted at the problematical issues detected by the Emergency Department Workplace Violence-Questionnaire. The corrective interventions were focused on an engineering level (i.e. absence of areas for patients/clients to de-escalate, absence of alarm systems) and regarding the organizational environment (i.e. absence of a Workplace Violence Task Force to assess workplace violence risk and develop solutions, working alone). CONCLUSION: The proposed questionnaire proved to be a valid, structured, and reliable tool for assessing the risk of workplace violence in the targeted emergency departments and allowed for the identification of improvement actions targeted at specific critical issues which could be minimized through strategic interventions.

An acute febrile outbreak in a refugee community of an Italian asylum seeker center: lessons learned.

OBJECTIVES: The management of infectious outbreaks in closed settings represents an important public health issue. An outbreak of acute febrile syndrome affecting 22 refugees resident at the Asylum Seekers Centre of Castelnuovo di Porto in Rome has been reported, and the preventive and control measures adopted have been described as an example of public health safety. METHODS: Pharyngeal swab and whole-blood samples were collected from 22 cases observed and analyzed for standard bacterial cultures and respiratory and herpesviruses by qualitative CLART PneumoVir2 and Entherpex microarray. RESULTS: A possible respiratory-transmitted etiology and a concomitant reactivation of multiple herpesviruses have been evidenced. The epidemiological investigation showed that the spread of the epidemic was promoted because patients were hosted in neighboring rooms or in the same room, facilitating the rapid spread of infectious disease. CONCLUSIONS: The potential way of transmission was supposed, and preventive measures for infection control were adopted. The measures adopted are an example of best practice for outbreak management, and the microbiological surveillance is recommended for public health improvement.

Preliminary assessment of rotating shiftwork risk in a twenty-four hours hospital department.

BACKGROUND: The safety and health of healthcare workers employed in twenty-four-hour hospital wards and exposed to rotational shiftwork (RS), including night shift, is an hot topic of international literature; in fact shift workers incur increased rates of burnout, accidents and injuries, absenteeism and, consequently, reduced work efficiency than non-shift workers. The aims of the present study were: 1) to analyze the occupational risk associated with RS in healthcare sector and 2) to detect the consequent interventions effective in minimizing RS risk. METHODS: The authors designed a questionnaire entitled Rotating Shiftwork Questionnaire (RSQ) which is made up of two sections: 1) Sentinel Events; 2) Risk Factors. The authors used the RSQ to evaluate the RS-Risk among homogeneous groups employed in a twenty-four-hour hospital department. RESULTS: Results. The authors found a medium level of risk among all homogeneous groups. The analysis led to suggest organizational interventions for reducing the sources of RS-risk among healthcare workers. CONCLUSION: The proposed questionnaire revealed effective in approaching the assessment of RS-risk; the findings were also useful in prioritizing and implementing strategic interventions aimed to moderate the occupational risk related to RS.

Acute low back pain among registered nurses. Organizational implications for practice management.

BACKGROUND: To date there is a lack of evidence about the impact of shiftwork on the occurrence of acute low back pain among registered nurses working non-traditional shifts, including nights and 12-hour shifts. The objectives of the present study were: 1) to investigate the impact of shiftwork, physical activity and body mass index on the occurrence of acute low back pain among female shift-registered nurses; 2) to suggest preventive interventions. METHODS: The author conducted a cross-sectional nested case-control analysis of data concerning acute low back pain and staffing data for female registered nurses employed in hospital wards. RESULTS: The analysis found a relationship between acute low back pain and nightshift, extended shifts, obesity; the adoption of forward rotating schedules proved to be effective in minimizing the frequency of acute low back pain. CONCLUSIONS: The findings showed that the prevention of acute low back pain should consider interventions aimed at minimizing not only physical ergonomic factors, but also organizational risks and lifestyle factors.

Role of biomarkers in adult sepsis and their application for a good laboratory practice: a pilot study.

This study measured Procalcitonin (PCT), Presepsin (PRE-S) and pro-Adrenomedullin (pro-ADM) in intensive care unit (ICU) patient’s blood to assess their contribution to accurate diagnosis of sepsis and potential predictive impact on prognosis. The final aim was to improve the use of infection biomarkers for optimizing the impact of laboratory medicine on clinical outcomes, focusing on the good management of resources designed to produce maximum effectiveness and efficiency. Sixty-four adult patients were studied during their hospitalization in ICU; blood samples were collected and categorized according to their clinical diagnosis and illness severity, and sepsis marker levels were measured on automated immunoassay platforms. PCT, PRE-S and pro-ADM infection markers were significantly lower in controls than in sepsis or septic shock groups. The area under the curve, by ROC curve analysis, was 0.945 for PCT, 0.756 for PRE-S and 0.741 for pro-ADM. Sepsis diagnostic accuracy was not improved by combining PCT, PRE-S and pro-ADM measures. Preliminary data demonstrated that, despite PRE-S and pro-ADM being able to differentiate between septic and non-septic patients with accuracy, PCT remains the most reliable marker available. The results obtained still do not allow us to consider a combination of markers, because it would merely increase laboratory costs without improving diagnostic performance. Furthermore, the results confirm a possible prognostic role of pro-ADM in septic states, but no correlation between biomarker levels and survival at 48 h was detected. Hence PCT, PRE-S, nor pro-ADM can be used to predict short-term prognosis.

Renal cavernous hemangioma: robot-assisted partial nephrectomy with selective warm ischemia. Case report and review of the literature.

Renal hemangioma is a relatively rare benign tumor with a wide range of clinical and radiological presentation, not easy to differentiate preoperatively from a renal cancer. Due to its benign nature complete surgical resection is the recommended therapy and is considered curative. A 73-year old male patient followed-up for a lung carcinoma and a chronic renal failure underwent a CT scan showing a 35-mm mass of the inferior pole of the left kidney. The patient underwent robot-assisted partial nephrectomy with left inferior pole selective warm ischemia. The outcome was favorable and no repercussions on the renal reserve were observed postoperatively. Histopathological characteristics of the surgical specimen were consistent with renal cavernous hemangioma. A robot-assisted operation allows the fine dissection required to carry out a bloodless nephron-sparing surgery without a complete warm ischemia. The use of robot could be noteworthy for nephron-sparing surgery in cases of concomitant chronic renal failure.
