Background: Elevated C-reactive protein (CRP) was shown to be associated with an increased risk for new-onset atrial fibrillation (AF) in ST elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI); however, the optimal time frame to measure CRP for risk stratification is not known.

Objectives: To evaluate the relation between the change in CRP over time (CRP velocity [CRPv]) and new-onset AF among STEMI patients treated with primary PCI.

Methods: We included 801 STEMI patients who underwent PCI between 2007 and 2017 and had their CRP measured with a wide range assay (wr-CRP) at least twice during the 24 hours after admission. CRPv was defined as the change in wr-CRP concentration (mg/l) divided by the change in time (in hours) between the two measurements. Patient medical records were reviewed for occurrence of new-onset AF.

Results: New onset AF occurred in 45 patients (6%). Patients with new onset AF had significantly higher median CRPv (1.27 vs. 0.43 mg/l/h, P = 0.002). New-onset AF during hospitalization occurred in 3.4%, 4.5 %, and 9.1% of patients in the first, second and third CRPv tertiles, respectively (P for trend = 0.006). In a multivariable logistic regression, adjusting for clinical variables the odds ratios for new onset AF was 1.93 (95% confidence interval 1.0–3.59, P = 0.04) for patients in the third CRPv tertile.

Conclusion: CRPv might be an independent and rapidly measurable biomarker for new-onset AF following primary PCI in STEMI patients.

Background: Pancreatic trauma is uncommon in pediatric patients and presents diagnostic and therapeutic challenges. While non-operative management (NOM) of minor pancreatic injuries is well accepted, the management of major pancreatic injuries remains controversial.

Objectives: To evaluate management strategies for major blunt pancreatic injury in children.

Methods: Data were retrospectively collected for all children treated for grade III or higher pancreatic injury due to blunt abdominal trauma from 1992 to 2015 at two medical centers. Data included demographics, mechanism of injury, laboratory and imaging studies, management strategy, clinical course, operative findings, and outcome.

Results: The cohort included seven boys and four girls aged 4–15 years old (median 9). Six patients had associated abdominal (mainly liver, n=3) injuries. The main mechanism of injury was bicycle (handlebar) trauma (n=6). Five patients had grade III injury and six had grade IV. The highest mean amylase level was recorded at 48 hours after injury (1418 U/L). Management strategies included conservative (n=5) and operative treatment (n=6): distal (n=3) and central (n=1) pancreatectomy, drainage only (n=2) based on the computed tomography findings and patient hemodynamic stability. Pseudocyst developed in all NOM patients (n=5) and two OM cases, and one patient developed a pancreatic fistula. There were no differences in average length of hospital stay.

Conclusions: NOM of high-grade blunt pancreatic injury in children may pose a higher risk of pseudocyst formation than OM, with a similar hospitalization time. However, pseudocyst is a relatively benign complication with a high rate of spontaneous resolution with no need for surgical intervention.

Background: Low folate levels are associated with megaloblastic anemia, neural tube defects, and an increased risk of cancer. Data are scarce regarding the sex aspect of this deficiency.

Objectives: To assess sex differences in folate levels in a large cohort of patients and to investigate the effect of low folate levels on homocysteine concentrations.

Methods: Data were collected from medical records of patients examined at a screening center in Israel between 2000 and 2014. Cross sectional analysis was conducted on 9214 males and 4336 females.

Results: The average age was 48.4 ± 9.5 years for males and 47.6 ± 9.4 years for females. Average folate levels were 19.2 ± 8.6 and 22.4 ±10.3 nmol/L in males and females, respectively (P < 0.001). The prevalence of folate levels below 12.2 nmol/L was 19.5% in males compared to 11.6% in females (P < 0.001). In patients with low folate levels and normal B12 levels, homocysteine levels above 15 μmol/L were found in 32.4% of males and 11.4% of females (P < 0.001). Males had a significantly higher odds ratio (OR) of having folate levels below 12.2 nmol/L: OR 1.84 (95% confidence interval [95%CI] 1.66–2.05) in a non-adjusted model, and OR 2.02 (95%CI 1.82–2.27) adjusted for age, smoking status, body mass index, kidney function, albumin, and triglycerides levels.

Conclusions: Folate levels are lower in males compared to females, which may contribute to the higher homocysteine levels found in males and thus to their increased risk of developing atherosclerosis and coronary artery disease.

Background: Patients with critical limb ischemia (CLI) involving the below-the-knee (BTK) arteries are at increased risk of limb loss. Despite improvement in endovascular modalities, it is still unclear whether an aggressive approach results in improved limb salvage.

Objectives: To assess whether an aggressive approach to BTK arterial disease results in improved limb salvage.

Methods: A comparative study of two groups was conducted. Group 1 included patients treated between 2012 and 2014, primarily with transfemoral angioplasty of the tibial arteries. Group 2 included patients treated between 2015–2019 with a wide array of endovascular modalities (stents, multiple tibial artery and pedal angioplasty, retrograde access). Primary endpoint was freedom from amputation at 4 years.

Results: A total of 529 BTK interventions were performed. Mean age was 71 ± 10.6 years, 382 (79%) were male. Patients in group 1 were less likely to be taking clopidogrel (66% vs. 83%, P < 0.01) and statins (72 % vs. 87%, P < 0.01). Several therapeutic modalities were used more often in group 2 than in group 1, including pedal angioplasty (24 vs. 43 %, P = 0.01), tibial and pedal retrograde access (0 vs. 10%, P = 0.01), and tibial stenting (3% vs. 25%, P = 0.01). Revascularization of two or more tibial arteries was performed at a higher rate in group 2 (54% vs. 50%, P = 0.45). Estimated freedom from amputation at 40 months follow-up was higher in group 2 (53% vs. 63%, P = 0.05).

Conclusions: An aggressive, multimodality approach in treating BTK arteries results in improved limb salvage.

Background: Idiopathic pulmonary fibrosis (IPF) has poor prognosis. Anti-fibrotic treatment has been shown to slow disease progression. Lung transplantation (LTx) offers a survival benefit. The 5-year survival after LTx in IPF is between 40 and 50%

Objectives: To evaluate which IPF patients have better prognosis following LTx.

Methods: A retrospective study was conducted with all IPF patients who had undergone LTx in the Rabin Medical Center between 2010 and 2018. We collected data on pre-evaluation of pulmonary function tests, echocardiographic and right heart catherization, and anti-fibrotic treatments. The Kaplan-Meier method was used for survival analysis.

Results: Among148 patients who underwent LTx, 58 were double LTx (DLT) and 90 single LTx (SLT). Mean age was 58.07 ± 9.78 years; 104 males and 44 females. DLT patients had significantly lower survival rates than SLT in the short and medium term after LTx. Patients with saturation above 80% after the 6-minute walk test (6MWT) had higher survival rates. Patients over 65 years of age had a lower survival rates. Those with pulmonary hypertension (PHT) above 30 mmHg had a poorer prognosis with lower survival rates.

Conclusions: IPF patients with higher mean PHT, older age (> 65 years), and desaturation following 6MWT had lower survival rates following LTx. DLT may decrease survival rate compared to SLT just for the short and medium period of time after LTx. These results may lead to better selection of IPF patient candidates for LTx. Additional studies are warranted for choosing which patients will have better prognosis after LTx.

Background: The World Health Organization classified coronavirus disease-19 (COVID-19) as a pandemic and recommends strict restrictions regarding most aspects of daily activities.

Objectives: To evaluate whether the pandemic has changed the prenatal care and pregnancy outcome in pregnant women without COVID-19.

Methods: The authors conducted a cross-sectional study to describe changes in outpatient clinic visits and to compare the rates of cesarean and instrumental deliveries between two periods of time: March–April 2020 (during the COVID-19 outbreak) with March–April of the preceding year, 2019.

Results: During the COVID-19 outbreak, visits to obstetric triage, gynecologic triage, high-risk clinic, and ultrasound units decreased by 36.4%, 34.7%, 32.8%, and 18.1%, respectively. The medical center experienced a 17.8% drop in the total number of births (610 births) compared with March and April 2019 (742 births). During the outbreak women were more likely to be nulliparous (33.3% vs. 27.6%, P = 0.02) and present with hypertensive disorders during pregnancy (7.5% vs. 4%, P = 0.005) or gestational diabetes (13% vs. 10%, P = 0.03). More epidural analgesia was used (83.1% vs. 77.1%, P = 0.006). There were more operative vaginal deliveries during the outbreak (16.7% vs. 6.8%, P = 0.01). All other maternal and neonatal outcomes were comparable between the two periods.

Conclusions: The medical facility experienced a major decline in all aspects of the routine obstetrics activities during the time of the pandemic. The higher rate of operative vaginal deliveries among nulliparous may be associated with the pandemic effect on the rate of high-risk patients

Background: Survivors of acute myocardial infarction (AMI) are at increased risk for recurrent cardiac events and tend to use excessive healthcare services, thus resulting in increased costs.

Objectives: To evaluate the disparities in healthcare resource utilization and costs throughout a decade following a non-fatal AMI according to sex and ethnicity groups in Israel.

Methods: A retrospective study included AMI patients hospitalized at Soroka University Medical Center during 2002–2012. Data were obtained from electronic medical records. Post-AMI annual length of hospital stay (LOS); number of visits to the emergency department (ED), primary care facilities, and outpatient consulting clinics; and costs were evaluated and compared according sex and ethnicity groups.

Results: A total of 7685 patients (mean age 65.3 ± 13.6 years) were analyzed: 56.8% Jewish males (JM), 26.6% Jewish females (JF), 12.4% Bedouin males (BM), and 4.2% Bedouin females (BF). During the up-to 10-years follow-up (median 5.8 years), adjusted odds ratios [AdjOR] for utilizations of hospital-associated services were highest among BF (1.628 for LOS; 1.629 for ED visits), whereas AdjOR for utilization of community services was lowest in BF (0.722 for primary clinic, 0.782 for ambulatory, and 0.827 for consultant visits), compared with JM. The total cost of BF was highest among the study groups (AdjOR = 1.589, P < 0.01).

Conclusions: Long-term use of hospital-associated healthcare services and total costs were higher among Bedouins (especially BF), whereas utilization of ambulatory services was lower in these groups. Culturally and economically sensitive programs optimizing healthcare resources utilization and costs is warranted.

Background: The number of investigative esophagogastroduodenoscopies (EGD) in children has increased over several decades, despite their unclear diagnostic yields.

Objectives: To evaluate the indications for performing EGD, their diagnostic yields, and consequences on pediatric patient management.

Methods: A retrospective chart review was performed of consecutive pediatric patients aged 0–18 years, who underwent EGD between January and August 2014.

Results: During the study period, 547 EGD were performed on 478 children. The most frequent indications were suspected celiac disease, chronic non-specific abdominal pain, persistent Helicobacter pylori infection, and gastrointestinal hemorrhage. The yield of the diagnostic EGD was 59.2%, and the most common new diagnoses were celiac disease (28%), Helicobacter pylori-positive gastritis (16.5%), and Crohn’s disease (5.4%). Of the patients with documented follow-up, 74.1% reported improved symptoms. Procedures performed for chronic unexplained abdominal pain had significantly lower yields (26.2%) and only 39.3% improved at follow-up.

Conclusions: Our findings suggest a general high diagnostic yield for EGD in pediatric patients, stemming mainly from patients in whom a specific condition was suspected a priori. However, the role of the procedure in the diagnosis and management of non-specific gastrointestinal complaints was minor suggesting that EGD may be superfluous for some of these patients.

Background: The introduction of pneumococcal conjugate vaccine-13 (PCV-13) has reduced the burden of invasive pneumococcal disease.

Objective: To characterize true positive blood cultures of children who presented to our hospital following implementation of the PCV-13 vaccine.

Methods: A retrospective study was conducted on positive blood cultures of children presenting with fever from 2010–2017. Subjects were divided into two age groups: a younger group 3–36 months and an older group 3–18 years. Patients were classified as either having or not having a focus of infection at the time of their bacteremia. Pneumococcal isolates were typed at Israel's Streptococcal Reference Laboratory.

Results: The samples included 94 true positive blood cultures. Focal infection with concomitant bacteremia was more common than bacteremia without a focus both overall: 67/94 (71%) vs. 27/94 (28.7%), P <0.001 as well as in the two groups: 32/48 (66%) vs. 16/48 (33%), P = 0.02 in the younger group and 35/46 (76%) vs. 11/46 (24%), P = 0.001 in the older group. Streptococcus pneumoniae was the most common pathogen overall, 27/94 (29%), and in the younger group, 21/48 (44%), but rare in the older group, 6/46 (13%). In the latter, Brucella species predominated, 12/46 (26%), along with Staphylococcus aureus 12/46 (26%).

Conclusions: Our findings are consistent with other studies reporting decreased pneumococcal bacteremia, bacteremia primarily accompanying focal infection, and changing etiological agents among PCV-13-vaccinated children. Brucella species was prominent in older children with osteoarticular infections. Ongoing surveillance is warranted to better understand the implications of PCV-13.

Background: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) is associated with decreased perioperative morbidity and mortality.

Objectives: To report the outcomes of EVAR among patients older than 80 years of age.

Methods: In this retrospective study, we reviewed patients older than 80 years of age who underwent elective EVAR at our institution between 2007 and 2017. The demographics, perioperative morbidity and mortality, and long-term results are reported.

Results: During the study period, 444 patients underwent elective EVAR for AAAs. Among them 128 patients (29%) were > 80 years of age. Mean age was 84 ± 3.4 (range 80–96) years, and 110 patients (86%) were male. The EVAR was technically successful in 127 patients (99%) and there were intraoperative mortalities. Within 30 days of the surgery, nine patients (7%) died. Major and minor adverse events occurred in 26 (20%) and 59 (46%) patients, respectively. Factors associated with increased risk of perioperative morbidity and mortality included chronic kidney disease, peripheral artery disease, and the existence of three or more co-morbidities.

Conclusions: EVAR in the elderly can be performed with a high rate of success; however, it is associated with a substantial rate of morbidity and mortality, particularly when patients present with multiple co-morbidities. When performing EVAR in this population group, the risk of rupture must be considered opposed to the life expectancy of these patients and the risk of perioperative morbidity and mortality.
