Background: Patients with severe coronavirus disease-2019 (COVID-19) are susceptible to superimposed infections.

Objectives: To describe COVID-19 patients who presented with complications due to Candida bloodstream co-infection (candidemia) and their outcome in a single center in northern Israel (Emek Medical Center) during the second outbreak of COVID-19 in Israel (15 June 2020 to 20 September 2020).

Methods: A retrospective study of COVID-19 patients presenting with candidemia was conducted, including clinical and laboratory data. The incidence of candidemia among hospitalized COVID-19 patients was compared to a historical cohort of non-COVID-19 controls.

Results: Three COVID-19 patients complicated with candidemia were documented. All three patients died shortly after the detection of candidemia. Three different Candida sp. were isolated from the blood cultures: C. albicans, C. parapsilosis, and C. glabrata. The incidence of candidemia among COVID-19 patients was 0.679 episodes per 1000 hospital days.

Conclusions: Our small sample suggests a much higher incidence of candidemia among COVID-19 patients compared to a historical cohort of non-COVID-19 controls. All clinicians treating COVID-19 patients in GICU should be aware of this complication

Background: Proximal femoral fractures (PFF) are among the most common injuries in the elderly population treated by orthopedic surgeons. Postoperative complications, especially infections, are of great importance due to their effect on patient mortality and morbidity and healthcare costs.

Objectives: To assess the main causes for postoperative infection among PFF patients.

Methods: We conducted a retrospective analysis of PFF patients in our medical center between 2015 and 2017. Patients were divided into two groups based on whether there was postoperative infection during immediate hospitalization and 30 days after surgery. Factors such as time from admission to surgery, duration of surgery, and length of stay were analyzed. Groups were analyzed and compared using a t-test, chi-squared and Fisher’s exact tests.

Results: Of 1276 patients, 859 (67%) underwent closed reduction internal fixation, 67 (5%) underwent total hip arthroplasty, and 350 (28%) underwent hemiarthroplasty. Of the total, 38 patients (3%) were diagnosed with postoperative infection. The demographics and co-morbidities were similar between the two study groups. The incident of infection was the highest among patients undergoing hemiarthroplasty (6%, P < 0.0001). Length of hospitalization (15 vs. 8 days, P = 0.0001) and operative time (117 vs. 77 minutes, P = 0.0001) were found to be the most significant risk factors for postoperative infection.

Conclusions: Predisposition to postoperative infections in PPF patients was associated with prolonged length of surgery and longer hospitalization. We recommend optimizing fast discharge, selecting the appropriate type of surgery, and improving surgical planning to reduce intraoperative delays and length of surgery.

Background: Adenovirus infections are prevalent in children. They usually cause a mild self-limited disease. However, this infection can be associated with considerable morbidity and mortality in specific populations, especially among immunocompromised children. Children with Down syndrome are susceptible to a higher frequency and increased severity of viral infections. Little is known about the severity and clinical course of adenovirus infections in children with Down syndrome.

Objectives: To characterize hospitalized children diagnosed with Down syndrome and presenting with adenovirus infection.

Methods: We performed a retrospective review of children admitted with adenovirus from January 2005 to August 2014 from a single tertiary pediatric medical center in Israel. Data were compared between patients with and without Down syndrome.

Results: Among the 486 hospitalized children with adenoviral infection, 11 (2.28%) were diagnosed with Down syndrome. We found that children with Down syndrome were more likely to experience a higher incidence of complications (18.2% vs. 2.4%, P = 0.008), a higher rate of admissions to the intensive care unit (36.4% vs. 2.4%, P < 0.001), and more prolonged hospitalizations (17 ± 15.9 days compared to 4.46 ± 3.16, P = 0.025).

Conclusions: Children with Down syndrome who were hospitalized with adenovirus infection represent a high-risk group and warrant close monitoring. If a vaccine for adenovirus becomes available, children with Down syndrome should be considered as candidates

Background: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited.

Objectives: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients.

Methods: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared.

Results: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78–157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7–30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP.

Conclusion: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered

Background: The incidence of congenital cytomegalovirus (CMV) infection in Israel is 0.7%. Only 10–15% are symptomatic. Valganciclovir has been shown to improve hearing and neurodevelopmental outcomes in neonates with symptomatic congenital CMV infection. Targeted examination of infants who fail routine neonatal hearing screening or have clinical or laboratory findings suggestive of symptomatic congenital CMV infection may be a cost-effective approach.

Objectives: To assess the possibility of targeted examination for the detection of newborns with symptomatic congenital CMV infection.

Methods: A prospective observational study was conducted in 2014–2015 at two medical centers in northern Israel. Included were all newborns who were tested in the first 3 days of life by polymerase chain reaction (PCR) for urine CMV DNA (n=692), either for failure the hearing screening (n=539, 78%), clinical or laboratory findings suggestive of symptomatic congenital CMV infection, or primary CMV infection during pregnancy (n=153, 22%).

Results: During the study period 15,433 newborns were born. The predicted rate of infection was 10–15% (symptomatic) of 0.7% of newborns, namely 0.07–0.105% or 10–15 infants. In fact, 15 infants (0.11%, 95% confidence interval 0.066–0.175) were diagnosed with symptomatic congenital CMV infection, 2/539 (0.37%) in the failed hearing group and 13/153 (8%) in the clinical/laboratory findings group. The incidence of symptomatic congenital CMV infection was within the predicted range.

Conclusions: Targeted examination of only 4.5% (n=692) of newborns detected the predicted number of infants with symptomatic congenital CMV infection in whom valganciclovir therapy is recommended

Background: Peritoneal dialysis (PD) is a treatment option for patients with end-stage renal disease (ESRD) and cardiorenal syndrome (CRS).

Objectives: To evaluate the outcome of this patient population.

Methods: A retrospective study was conducted of patients who underwent an open or laparoscopic insertion of a PD catheter at our institution between 2009 and 2017. Data included demographics, peri-operative parameters, and long-term outcome. Patient and technique survival curves are presented, including subgroup analysis by method of catheter insertion and techniques for infection prevention.

Results: The study population included 95 men and 42 women, aged 65.7 ± 12.4 years. Mean follow-up was 34.6 ± 27.3 months. Open insertion was performed in 113 cases, while 24 underwent laparoscopic insertion. There was no difference in technique survival between these groups (P = 0.943). Removal of the catheter was required in 66% of patients. Median technique survival was 12.1 months. Two-year technique survival was 37% and 5-year technique survival was 12%. The leading cause for catheter removal was infection (69%). Application of measures for prevention of infections were significantly associated with prolonged technique survival (P = 0.001). Technique survival after 2 years was 38% with the application of a single measure and 57% with the application of two measures (P = 0.001). CRS patients (n=24) had a significantly lower overall survival rate (2-year survival 20% vs. 74%, P = 0.001).

Conclusions: The method of catheter insertion has no effect on technique survival. Prevention of infections is the most significant factor for improving the technique survival rates.

Extremely preterm infants are at high risk for mortality and morbidity including neurodevelopmental impairment from invasive Candida infections. Prophylactic antifungal therapy has been shown to reduce both colonization and invasive candidemia in high-risk preterm infants. Prophylactic treatment should be started in the first 48 to 72 hours after birth to extremely low birth weight (ELBW) infants (weighing ≤ 1000 grams at birth) or below 27 weeks gestation age with risk factors, or in any NICU with moderate (5–10%) or high (≥ 10%) rates of invasive candidiasis. Studies demonstrated the benefits of fluconazole prophylaxis regarding its safety of the short-term and long-term without the development of fungal resistance. Empiric antifungal therapy may lower mortality and improve outcomes

Background: Channeling medical resources for coronavirus disease-2019 (COVID-19) management can potentially endanger routine healthcare practices. As a preventive measure, a department of obstetrics and gynecology in Israel constructed a separate, designated complex for its COVID-19-exposed patients.

Objectives: To evaluate the effect of the COVID-19 pandemic infection control measures on obstetric care in the obstetrical emergency department and delivery unit.

Methods: The authors collected data retrospectively from February 2020 to March 2020 and compared it to data of a parallel period in 2019.

Results: From 1 February 2020 to 28 March 2020, 3897 women were referred to the emergency department (ED), compared to 4067 the previous year. Mean duration of treatment until decision and referral indications did not differ between 2020 and 2019 (207 vs. 220 minutes, P = 0.26; urgent referrals 58.8% vs. 59.2%, P = 0.83). A per-week comparison showed a significant reduction in ED referrals only in the last week of the period (337 [2020] vs. 515 [2019], P < 0.001). The proportion of women admitted to the delivery unit in active labor was significantly higher in the last three weeks (39.1% vs. 28.2%, P = 0.005). During February and March 2020, 1666 women delivered, compared to 1654 during February and March 2019. The proportion of types and modes of delivery did not differ. In a per-week comparison, the number of deliveries did not differ (mean 208 vs. 206, P = 0.88).

Conclusions: With timely preparation and proper management, negative impact of COVID-19 can be reduced in obstetrical emergency departments.

There is a high prevalence of olfaction changes, especially in the early presentation, in COVID-19 patients. The mechanisms through which the virus leads to anosmia/hyposmia is still not fully understood. However, olfaction changes could be used as an indication for testing or quarantine. Screening for infections and other diseases by recognizing volatile organic compounds (VOCs) has been previously conducted. Hence, if the coronavirus infection also results in VOCs excretion, physicians could “smell” the virus by using electronic noses. We conducted a literature review on olfaction changes and the COVID-19. Our results suggest that these changes could be used an indication for early testing, even as an isolated symptom. We propose that the electronic nose be used as a future screening tool, especially in agglomeration spaces such as airports, for screening for the COVID-19 infection
