Peripheral Blood Eosinophilia in Patients with Diabetic Foot Infection Receiving Long-Term Antibiotic Therapy.

Background: The eosinophil level in peripheral blood increases in response to various conditions, the most common being medication use. Since the outcome of increased levels of eosinophils can range from a benign finding to extensive damage to host organs and systemic consequences, this finding raises concern among clinicians. We aimed to assess the prevalence of prolonged antibiotic-therapy-induced eosinophilia and possible outcomes. Methods: We conducted a retrospective cohort study of diabetic patients admitted to the orthopedic department from December 2016 through December 2020 due to a moderate to severe diabetic foot infection and who received at least 14 days of antibiotic therapy. Patients were identified retrospectively through the orthopedic department registry, and their files were reviewed, extracting demographics, laboratory test results, antibiotic treatment, and outcomes. Results: The cohort included 347 patients; a total of 114 (32.8%) developed eosinophilia during the follow-up period. Patients who developed eosinophilia had a significantly longer duration of antibiotic treatment (p < 0.001) and a significantly longer hospitalization (p = 0.001). For multivariable analysis, the independent risk factors predicting drug-induced eosinophilia included older age, higher eosinophil count on admission (per quantile) and higher platelet count on admission (per quantile) (p = 0.012, p < 0.001, p = 0.009, respectively). There was no evidence of complications in patients who developed eosinophilia compared to patients who did not. No significant association with a specific type of antibiotic was found. Conclusions: We found a higher incidence of drug-induced eosinophilia than expected or previously described. The factors associated with eosinophilia included age and higher baseline eosinophil and platelet levels but not antibiotic type.

An international multicenter study comparing COVID-19 omicron outcomes in patients with hematological malignancies treated with obinutuzumab versus rituximab.

OBJECTIVES: Hematological malignancy (HM) patients treated with anti-CD20 monoclonal antibodies are at higher risk for severe COVID-19. A previous single-center study showed worse outcomes in patients treated with obinutuzumab compared to rituximab. We examined this hypothesis in a large international multicenter cohort. METHODS: We included HM patients from 15 centers, from five countries treated with anti-CD20, comparing those treated with obinutuzumab (O-G) to rituximab (R-G) between December 2021 and June 2022, when Omicron lineage was dominant. RESULTS: We collected data on 1048 patients. Within the R-G (n = 762, 73%), 191 (25%) contracted COVID-19 compared to 103 (36%) in the O-G. COVID-19 patients in the O-G were younger (61 ± 11.7 vs. 64 ± 14.5, p = 0.039), had more indolent HM diagnosis (aggressive lymphoma: 3.9% vs. 67.0%, p < 0.001), and most were on maintenance therapy at COVID-19 diagnosis (63.0% vs. 16.8%, p < 0.001). Severe-critical COVID-19 occurred in 31.1% of patients in the O-G and 22.5% in the R-G. In multivariable analysis, O-G had a 2.08-fold increased risk for severe-critical COVID-19 compared to R-G (95% CI 1.13-3.84), adjusted for Charlson comorbidity index, sex, and tixagevimab/cilgavimab (T-C) prophylaxis. Further analysis comparing O-G to R-G demonstrated increased hospitalizations (51.5% vs. 35.6% p = 0.008), ICU admissions (12.6% vs. 5.8%, p = 0.042), but the nonsignificant difference in COVID-19-related mortality (n = 10, 9.7% vs. n = 12, 6.3%, p = 0.293). CONCLUSIONS: Despite younger age and a more indolent HM diagnosis, patients receiving obinutuzumab had more severe COVID-19 outcomes than those receiving rituximab. Our findings underscore the need to evaluate the risk-benefit balance when considering obinutuzumab therapy for HM patients during respiratory viral outbreaks.

Beating the clock: Reduced time to first antibiotic dose administration following an audit and feedback intervention.

OBJECTIVE: Quality improvement interventions and policy revisions have been shown to improve clinical practice and patient outcomes. This study evaluated an intervention to shorten the time from the first antibiotic dose ordering to its administration in patients hospitalised with bacterial infections. METHODS: An intervention consisting of a weekly email report to nurse and physician leaders in hospital departments was introduced. The report included the percentage of patients who received their first antibiotic dose within 3 hours and details of those who did not. Interrupted time series analysis was used to compare the delay between the order and administration of antibiotics in various wards (surgical and medical) and daily nursing shifts. RESULTS: The total number of orders pre-intervention and post-intervention was 58 320 and 52 127, respectively. The most protracted delays were observed during the morning shift in the surgical and medical wards (161 and 100 minutes, respectively). Comparing the pre- to post-intervention time to the first antibiotic dose (TTFAD), a reduction in the morning shift was noted both in the surgical wards (87 minutes, 55%) and medical wards (37 minutes, 37%) and with a preserved trend (P < 0.001). The slope's angle before and after the intervention was not affected. CONCLUSION: Using an audit and feedback automatic weekly report significantly reduced TTFAD in hospitalised patients. This intervention proved to be simple and sustainable over time. Raising staff awareness of current medical care practices is an effective way of improving performance.

Community-based serum chloride abnormalities predict mortality risk.

INTRODUCTION: This population-based study aimed to investigate the prognostic value of ambulatory serum chloride abnormalities, often ignored by physicians. METHODS: The study population included all non-hospitalized adult patients, insured by "Clalit" Health Services in Israel's southern district, who underwent at least 3 serum chloride tests in community-based clinics during 2005-2016. For each patient, each period with low (≤97 mmol/l), high (≥107 mmol/l) or normal chloride levels were recorded. A Cox proportional hazards model was used to estimate the mortality risk of hypochloremia and hyperchloremia periods. RESULTS: 664,253 serum chloride tests from 105,655 subjects were analyzed. During a median follow up of 10.8 years, 11,694 patients died. Hypochloremia (≤ 97 mmol/l) was independently associated with elevated all-cause mortality risk after adjusting for age, co-morbidities, hyponatremia and eGFR (HR 2.41, 95%CI 2.16-2.69, p<0.001). Crude hyperchloremia (≥107 mmol/L) was not associated with all-cause mortality (HR 1.03, 95%CI 0.98-1.09 p = 0.231); as opposed to hyperchloremia ≥108 mmol/l (HR 1.14, 95%CI 1.06-1.21 p<0.001). Secondary analysis revealed a dose-dependent elevated mortality risk for chloride levels of 105 mmol/l and below, well within the "normal" range. CONCLUSION: In the outpatient setting, hypochloremia is independently associated with an increased mortality risk. This risk is dose-dependent where the lower the chloride level, the higher is the risk.

Multifaceted Strategy Improves Outcomes of Patients Hospitalized with a Diabetic Foot Infection.

Diabetic foot infections (DFIs) are associated with major morbidity, reduced quality of life and increased mortality. Osteomyelitis is a leading cause of lower-extremity amputation in diabetic patients. We aimed to examine whether a multifaceted strategy for treating hospitalized patients with a DFI effectively influenced microbiological culture results and outcomes. A retrospective cohort-study in a 1100-bed, tertiary-care university hospital was conducted. Adult patients with a DFI admitted to the orthopedics department between 2015 and 2019 were included. During the pre-intervention period (2015-2016), one general orthopedic department was in operation. In the post-intervention period (2017-2019), a second department was created with a designated "complicated wound unit". The multifaceted strategy included revising local guidelines for DFI culturing emphasizing bone cultures, correct sample handling, and adjusting antibiotic treatment to culture results. Additionally, a weekly multidisciplinary-team grand round was instigated and post-discharge outpatient follow-up was scheduled. 652 patients with DFIs were included; 101 during the pre-intervention period and 551 during the post-intervention period. Compared to the pre-intervention, during the post-intervention period mainly bone or deep-tissue cultures were performed (9.7% vs. 98.2%, P < 0.001). Bacteriology cultures in the pre-intervention versus post-intervention period revealed: among staphylococcus isolates, fewer methicillin-resistant Staphylococcus aureus detected (20.4% vs. 9.8%, P = 0.010); within Enterobacteriaceae isolates, fewer extended-spectrum ß-lactamase producing bacteria detected (51.6% vs. 23.6%, P < 0.001); a decrease in Pseudomonas aeruginosa isolates (28% vs. 10.6%, P < 0.001) and an increase in anaerobic bacterial isolates (0 vs. 11.1%, P < 0.001). On multivariate regression, the post-intervention period (ie multifaceted strategy) was a protective measure against readmissions (P = 0.007 OR 0.50 95% CI 0.30-0.82). We conclude that our interventive multifaceted strategy led to accurate bacterial diagnosis, de-escalation of antibiotic treatment and readmission reduction.

Bone mineral density in women newly diagnosed with breast cancer: a prospective cohort study.

Estrogen may have opposing effects on health, namely increasing the risk of breast cancer and improving bone health by increasing bone mineral density (BMD). The objective of this study was to compare dual-energy X-ray absorptiometry (DXA) BMD between women newly diagnosed with breast cancer and matched controls without breast cancer. Women newly diagnosed with breast cancer treated between April 2012 and October 2017 were prospectively enrolled. A control group was established of women with negative mammography or breast ultrasound, matched 1:1 by age, body mass index, parity, and the use of hormone replacement therapy. All those included had DXA BMD, and lab assessments at enrollment. Of 869 women with newly diagnosed breast cancer, 464 signed informed consent. Of the 344 who completed the study protocol, 284 were matched to controls. Overall, the mean age was 58 years. Compared to the control group, for the breast cancer group, the mean vitamin D level was lower (48.9 ± 19.0 vs. 53.8 ± 28.8 nmol/L, p = 0.022); and mean values were higher of total hip BMD (0.95 ± 0.14 vs. 0.92 ± 0.12 g/cm2, p = 0.002), T score (-0.38 ± 1.17 vs. -0.68 ± 0.98, p = 0.002), and Z score (0.32 ± 1.09 vs. 0.01 ± 0.88, p < 0.001). Among the women with breast cancer, no correlations were found of baseline BMD with tumor size or grade, nodal involvement, or breast cancer stage. We concluded that women with newly diagnosed breast cancer tend to have higher BMD than women with similar characteristics but without breast cancer. This implies that BMD might be considered a biomarker for breast cancer risk.

Secondary organizing pneumonia after recovery of mild COVID-19 infection.

A 36-year-old male with diffuse large B-cell lymphoma on maintenance rituximab therapy presented to the emergency department with high fever and fatigue. A chest X-ray showed a lobar infiltrate, 40 days before admission the patient suffered from a mild coronavirus disease 2019 (COVID-19) infection and fully recovered. PCR nasopharyngeal swab was negative for COVID-19. Comprehensive biochemical, radiological, and pathological evaluation including 18-fluorodeoxyglucose positron emission tomography with computed tomography and transbronchial lung biopsy found no pathogen or lymphoma recurrence. Treatment for pneumonia with antibiotic and antifungal agents was nonbeneficial. A diagnosis of secondary organizing pneumonia (OP) was made after pneumonia migration and a rapid response to corticosteroids. OP secondary to a viral respiratory infection has been well described. Raising awareness for post-COVID-19 OP has therapeutic and prognostic importance because those patients benefit from steroid therapy. We believe the condition described here is underdiagnosed and undertreated by doctors worldwide. Because of the ongoing global pandemic we are now encountering a new kind of patient, patients that have recovered from COVID-19. We hope that this case may contribute to gaining more knowledge about this growing patient population.

Treatment Modality and Second Primary Tumors of the Head and Neck.

INTRODUCTION: Second primary tumors (SPTs) in head and neck cancer are thought to occur from premalignant lesions that are present at the time of the primary tumor diagnosis. The association of the modality used to treat the primary lesion with SPT occurrence is not clear. OBJECTIVE: The aim of the study was to assess the incidence of SPTs in patients with head and neck malignancies, according to treatment modality. METHODS: We conducted a retrospective cohort study. All patients who were treated at Soroka Medical Center between 2000 and 2013 for a head and neck squamous cell carcinoma were assessed. Data analysis included tumor site of the primary and second primary and treatment modality of the primary tumor. In addition, demographics as well as habits were recorded as well. RESULTS: Of the 184 patients included in the cohort, SPT developed in 31 patients (17%) with a median time to diagnosis of 4.3 years. Smoking was reported in 74% of those with SPT and 78% of those without. The most common site for SPT was the lungs, with 13 cases, 42% of the total SPTs. Among patients who developed an SPT, for 12 of those with an index tumor in the oral cavity or oro-hypopharynx, 8 (67%) developed an SPT in the same location; for 18 of those with an index tumor in the larynx, 11 (61%) developed a SPT in the lungs and bronchi (p = 0.001). On multivariate analysis, the treatment modality used was not found to be associated with the occurrence of SPTs and the radiotherapy showed no protective or harmful effect (HR 0.64 p = 0.24). CONCLUSION: Treatment modality used for head and neck cancer does not seem to be associated with the occurrence of SPTs.

Clinical Characteristics and Prognosis of Idiopathic Acute Pancreatitis.

OBJECTIVE: Acute pancreatitis is a serious diagnosis with an increasing incidence in the Western world. In this study we sought to investigate the incidence of idiopathic AP and to compare clinical and prognostic characteristics of idiopathic cases with cases of AP with known etiology. METHODS: In this retrospective study of adult hospitalized patients diagnosed with acute pancreatitis between 2012 and 2015, a comparison was made between admissions of patients with known etiology and those for whom no cause was found. Primary outcome was defined as composite outcome of 30-day mortality and complications. RESULTS: Among 560 admissions of 437 patients with a primary diagnosis of acute pancreatitis, the main factors identified were gallstones (51.2%) and idiopathic pancreatitis (35.9%), with alcohol ranked third at only 4.8%. Mortality rate within 30 days of hospitalization was 2.9% and within one year was 7.1%. Use of lipid-lowering, anti-hypertensive, and anti-diabetic medications was more frequent among patients with "idiopathic" disease (70%, 68%, and 33% versus 59%, 56%, and 27%, respectively). Patients admitted with idiopathic AP, in comparison to patients with known AP etiology, had milder disease with shorter hospital stay (3 days versus 4, respectively), and less re-admission in 30 days (7.5% versus 21.2%). Idiopathic AP patients had better prognosis in terms of 30-day death and complication (HR 0.33, 95% CI 0.08-0.40, P<0.001). CONCLUSION: Idiopathic disease is common among acute pancreatitis patients; the two study groups differed in severity of disease and prognosis. Common use of medications with doubtful value suggests possible under-diagnosis of drug-induced acute idiopathic pancreatitis.

The Kinetics of an Antibiotic Stewardship Intervention: A Quasi-Experimental Study.

INTRODUCTION: Little is known about the kinetics and different phases of a successful antibiotic stewardship program (ASP) intervention. METHODS: We analyzed the trends of quarterly antibiotic use measured in defined daily dose (DDD)/100 days hospitalization using the Joinpoint Regression Program and interrupted time series analysis to objectively identify shifts in the trends of antibiotic use. We correlated these changes in trends with the introduction of a hospital-wide ASP intervention. RESULTS: The ASP intervention reduced the overall antibiotic use by 33%, from a prior steady state of 76.5 DDD/100 days hospitalization to a post-intervention steady state of 51.2 DDD/100 days hospitalization (p < 0.001). We identified four distinct phases in the trends: prior steady state (A), early intervention (B), accelerated phase (C), and post steady state (D). From A to B a change of slope (-1.46) [SE 0.37, 95% CI -2.23, -0.69 (p = 0.002)]; B to C, a further decrease of slope (-4.70) [SE 0.64, 95% CI -6.03, -3.37 (p = 0.001)]; between periods C and D, straightening out of the slope (+ 6.84) [SE 0.55, 95% CI 5.70, 7.98 (p < 0.001)] to a new post-intervention steady state. It took 1.5 years after completion of the intervention to reach the new steady state. CONCLUSIONS: We demonstrate that ASP interventions require time to achieve the maximal effect. Successful interventions require physicians to adapt new prescribing behaviors and gain confidence in the change; this adaptation can be a prolonged process and might even take years after the introduction of the ASP. These factors should be considered when planning and implementing ASP interventions.

The impact of a multimodel approach to designing a new orthopedic department.

OBJECTIVE: To determine whether a multifaceted approach effectively influenced antibiotic use in an orthopedics department. DESIGN: Retrospective cohort study comparing the readmission rate and antibiotic use before and after an intervention. SETTING: A 1,000-bed, tertiary-care, university hospital. PATIENTS: Adult patients admitted to the orthopedics department between January 2015 and December 2018. METHODS: During the preintervention period (2015-2016), 1 general orthopedic department was in operation. In the postintervention period (2017-2018), 2 separate departments were created: one designated for elective "clean" surgeries and another that included a "complicated wound" unit. A multifaceted strategy including infection prevention measures and introducing antibiotic stewardship practices was implemented. Admission rates, hand hygiene practice compliance, surgical site infections, and antibiotic treatment before versus after the intervention were analyzed. RESULTS: The number of admissions and hospitalization days in the 2 periods did not change. Seven-day readmissions per annual quarter decreased significantly from the preintervention period (median, 7 days; interquartile range [IQR], 6-9) to the postintervention period (median, 4 days; IQR, 2-7; P = .038). Hand hygiene compliance increased and surgical site infections decreased in the postintervention period. Although total antibiotic use was not reduced, there was a significant change in the breakdown of the different antibiotic classes used before and after the intervention: increased use of narrow-spectrum ß-lactams (P < .001) and decreased use of ß-lactamase inhibitors (P < .001), third-generation cephalosporins (P = .044), and clindamycin (P < .001). CONCLUSIONS: Restructuring the orthopedics department facilitated better infection prevention measures accompanied by antibiotic stewardship implementation, resulting in a decreased use of broad-spectrum antibiotics and a significant reduction in readmission rates.

Early Point-of-Care Ultrasound Assessment for Medical Patients Reduces Time to Appropriate Treatment: A Pilot Randomized Controlled Trial.

Numerous studies emphasize the diagnostic importance of point-of-care ultrasound (POCUS), but the level of evidence remains low as most data are gathered from observational studies. We conducted a pilot, randomized controlled trial to evaluate the effect of POCUS exam on medical patient's management and clinical outcomes. Patients presenting with chest pain or dyspnea were enrolled and randomly allocated to an early POCUS scan group and a control group. POCUS assessment, within 24 h of internal ward admission, was conducted only for the intervention group. The primary outcome was time to correct diagnosis. Secondary outcomes included time to appropriate treatment, POCUS-related rate of primary diagnosis alteration and new clinically relevant findings and time to hospital discharge. Sixty patients were enrolled. Thirty patients were randomly allocated to each study arm. The POCUS exam revealed clinically relevant findings among 79% of patients and led to alteration of the primary diagnosis among 28% of patients. Time to appropriate treatment was significantly shorter among patients in the POCUS group compared with the control group (median time of 5 h [95% confidence interval: 0.5-9] vs. 24 h [95% CI: 19-29] p = 0.014). The time needed to achieve correct diagnosis by the primary team was shorter in the POCUS group compared with the control group, yet it did not reach statistical significance (median time of 24 h [95% CI: 18-30] vs. 48 h [95% CI: 20-76], p = 0.12). These results indicate that POCUS assessment conducted early among patients with dyspnea or chest pain improves diagnostic accuracy and shortens significantly the time to appropriate treatment.

High prevalence of fibromyalgia syndrome among Israeli nurses.

OBJECTIVES: Stress has extensively been shown to trigger fibromyalgia syndrome (FM). Nursing is associated with high levels of stress. Our hypothesis was that nurses suffer from an increased prevalence of FM symptoms, and that these symptoms correlate with the levels of stress to which they are exposed in the course of their occupation. METHODS: The study was conducted as a targeted survey distributed to nursing staff in Soroka University Medical Centre, Beer-Sheva, Israel. Participants were asked to answer a questionnaire evaluating symptoms of FM, based on the current diagnostic criteria, which include the widespread pain index (WPI) and the symptom severity scale (SSS). Participants were further questioned regarding stressful experiences during their work and about post-traumatic symptoms as well as regarding work performance and motivation. RESULTS: 206 participants completed the study questionnaire (84.5% females and 15.5% males). Twenty (9.7%) participants of the sample fulfilled criteria for diagnosis of FM reaching rates among females and males of 10.9% and 3.1% respectively. The prevalence of FM in our study was related to age with the highest prevalence in the older age groups (p=0.012). FM symptoms were strongly correlated with work related stress and were strongly correlated with Post Traumatic Stress Disorder (PTSD)-related symptoms. Work-performance parameters did not show a significant correlation with FM parameters. CONCLUSIONS: FM is highly prevalent among nursing staff. Our findings point towards the possibility that work-related stress and traumatic events may play a major role in the development of FM symptoms among nurses. With aging this association is more significant.

A Multimodal Curriculum With Patient Feedback to Improve Medical Student Communication: Pilot Study.

INTRODUCTION: Despite the extraordinary amount of time physicians spend communicating with patients, dedicated education strategies on this topic are lacking. The objective of this study was to develop a multimodal curriculum including direct patient feedback and assess whether it improves communication skills as measured by the Communication Assessment Tool (CAT) in fourth-year medical students during an emergency medicine (EM) clerkship. METHODS: This was a prospective, randomized trial of fourth-year students in an EM clerkship at an academic medical center from 2016-2017. We developed a multimodal curriculum to teach communication skills consisting of 1) an asynchronous video on communication skills, and 2) direct patient feedback from the CAT, a 15-question tool with validity evidence in the emergency department setting. The intervention group received the curriculum at the clerkship midpoint. The control group received the curriculum at the clerkship's end. We calculated proportions and odds ratios (OR) of students achieving maximum CAT score in the first and second half of the clerkship. RESULTS: A total of 64 students were enrolled: 37 in the control group and 27 in the intervention group. The percentage of students achieving the maximum CAT score was similar between groups during the first half (OR 0.70, p = 0.15). Following the intervention, students in the intervention group achieved a maximum score more often than the control group (OR 1.65, p = 0.008). CONCLUSION: Students exposed to the curriculum early had higher patient ratings on communication compared to the control group. A multimodal curriculum involving direct patient feedback may be an effective means of teaching communication skills.

Clinical, Epidemiological, and Etiological Changes in Erythema Nodosum.

BACKGROUND: Erythema nodosum (EN) is the most common type of panniculitis, commonly secondary to infectious diseases. OBJECTIVES: To elucidate the causative factors and the clinical presentation of patients with EN (2004-2014) and to compare their data to those reported in a previous study. METHODS: A retrospective study was conducted of all patients diagnosed with EN who were hospitalized at Soroka University Medical Center (2004-2014). The clinical, demographic, and laboratory characteristics of the patients were compared to those in a cohort of patients diagnosed with EN from 1973-1982. RESULTS: The study comprised 45 patients with a diagnosis of EN. The most common symptoms of patients hospitalized with EN were arthritis or arthralgia (27% of patients). Patients with EN, compared to those reported in 1987, has significantly lower rates of fever (18% vs. 62% P < 0.001), streptococcal infection (16% vs. 44%, P = 0.003), and joint involvement (27% vs. 66%, P < 0.001). In addition, fewer patients had idiopathic causes of EN (9% vs. 32%, P = 0.006). CONCLUSIONS: In the past decades, clinical, epidemiological, and etiological changes have occurred in EN patients. The lowering in rate of fever, streptococcal infection, and joint involvement in patients with EN are probably explained by improvements in socioeconomic conditions. The significantly decreasing rate of idiopathic causes of EN is possibly due to the greater diagnostic accuracy of modern medicine. The results of the present study demonstrate the impact of improvements in socioeconomic conditions and access to healthcare on disease presentation.

Low thyroid-stimulating hormone and its persistence beyond the first trimester of pregnancy.

OBJECTIVE: To investigate predictors of low thyroid-stimulating hormone (TSH) persisting beyond the first trimester and associated pregnancy outcomes. METHODS: We retrospectively assessed the association between low first-trimester TSH and obstetric outcomes of singleton pregnancies in southern Israel between 2001 and 2011. We included women with first-trimester TSH and at least one other THS measurement. Clinical data were from maternity and community medical records. RESULTS: Among 3761 women, 185 (4.9%) had a TSH of 0.10 mIU/L or less in the first trimester. Multiple of the median human chorionic gonadotropin was higher in women with TSH of 0.40 mIU/L or less versus 0.41-4.0 mIU/L, but was not associated with higher rates of persistent low TSH. Maternal age (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.00-1.16; per yearly increment), free thyroxine (FT4; OR 1.11, 95% CI 1.03-1.20; per ng/dL increment), and TSH of 0.10 mIU/L or less (OR 3.06, 95% CI 1.38-6.80 vs 0.21-0.40 mIU/L) were independent predictors of persistent low TSH. No adverse pregnancy outcomes occurred in women with low first-trimester TSH. CONCLUSIONS: Low TSH persisting beyond the first trimester was more common with increasing maternal age, elevated FT4, and TSH below 0.10 mIU/L, but was not associated with obstetric complications.

Neonatal Risk Factors for Colonization with Extended-Spectrum Beta-Lactamase-Producing Bacteria in the Neonatal Intensive Care Unit.

BACKGROUND: Extended-spectrum beta-lactamase (ESBL) production is the most common antimicrobial resistance mechanism in the neonatal intensive care unit (NICU), with colonization and blood stream infections being a major threat to this population. Since 2013, all NICU admissions at our facility were screened twice weekly for ESBL colonization. OBJECTIVES: To determine independent risk factors for colonization of infants with ESBL-producing bacteria in the NICU. METHODS: A retrospective case study of ESBL-colonized infants vs. controls (matched by date of birth and gestational age) was conducted in the NICU of Soroka University Medical Center, Israel, between 2013 and 2014. Epidemiological, laboratory, and clinical data were extracted from medical files. Univariable and multivariable analyses were used to assess associations between ESBL colonization and possible clinical risk factors. RESULTS: Of 639 admissions during the study period, 87 were found to be ESBL-colonized (case infants) and were matched to 87 controls. Five case infants became infected (5.7%) with ESBL strains. Klebsiella pneumoniae was the most common isolated bacteria. The mean time from admission to colonization was 15 days. Univariable analysis showed an association of male gender and highest Apgar score at 1 and 5 minutes with ESBL colonization (P < 0.05). Multivariable analysis yielded only a possible association of higher Apgar score at 1 and 5 minutes (hazard ratio [HR] 1.515, 95% confidence interval [95%CI] 0.993-2.314; HR 1.603, 95%CI 0.958-2.682, respectively) with ESBL colonization. CONCLUSIONS: Future studies should focus on maternal colonization and possible strategies for preventing vertical transmission of ESBL strains to high-risk neonates.

[USING INFORMATION FROM COMPUTERIZED MEDICAL FILES TO DETERMINE THE RISK OF POOR OUTCOME IN EXTREMELY PRETERM INFANTS].

INTRODUCTION: During the last two decades preterm deliveries have been rising with increasing numbers of survivors at risk of abnormal outcomes. Characterization of risk factors for abnormal outcome is important for caregivers and patients' families. We hypothesized that it is possible to evaluate significant risk factors from computerized files early in life. OBJECTIVES: To evaluate data from computerized files that could help identify children born preterm at increased risk of abnormal outcomes without a neurodevelopmental exam. METHODS: This is a retrospective cohort study including children born at less than 29 weeks gestation and/or less than 1000 grams. The long term outcome was defined using data from the local child developmental center. Risk factors were retrieved from computerized files from birth until 3 years of age and assessed using univariate and multivariate analysis. RESULTS: A total of 74 children were included in the study; 30 with abnormal outcomes. The following parameters: Bedouin origin (p = 0.033), low 1 minute Apgar score (p = 0.044), late sepsis (p = 0.017), exposure to x-rays (p = 0.033), hospital based specialist visits (p = 0.017) and hospitalization (p = 0.035) were more common in the abnormal outcome group or increased its risk in univariate analysis. Bedouin origin (OR = 3.81-5.11), late sepsis (OR = 4.07-4.94) and hospital based specialist visits (OR = 4.67, 95% CI = 1.11-19.55) increased more than fourfold the risk of abnormal outcomes in multivariate analysis. CONCLUSIONS: This study has important implications as Bedouin origin and llate sepsis can be determined before discharge. Furthermore, follow-up of high risk children should be locally accessible. Prevention of late sepsis is of upmost importance, as well as awareness of specialists to the follow-up status of children born preterm.

Angiographic evidence of proliferative retinopathy predicts neuropsychiatric morbidity in diabetic patients.

INTRODUCTION: Diabetic retinopathy (DR) is a common vasculopathy categorized as either non-proliferative (NPDR) or proliferative (PDR),characterized by dysfunctional blood-retinal barrier (BRB) and diagnosed using fluorescein angiography (FA). Since the BRB is similar in structure and function to the blood-brain barrier (BBB) and BBB dysfunction plays a key role in the pathogenesis of brain disorders, we hypothesized that PDR, the severe form of DR, is likely to mirror BBB damage and to predict a worse neuropsychiatric outcome. METHODS: A retrospective cohort study was conducted among subjects with diabetes (N=2982) with FA-confirmed NPDR (N=2606) or PDR (N=376). Incidence and probability to develop brain pathologies and mortality were investigated in a 10-year follow-up study. We used Kaplan-Meier, Cox and logistic regression analyses to examine association between DR severity and neuropsychiatric morbidity adjusting for confounders. RESULTS: Patients with PDR had significantly higher rates of all-cause brain pathologies (P<0.001), specifically stroke (P=0.005), epilepsy (P=0.006) and psychosis (P=0.024), and a shorter time to develop any neuropsychiatric event (P<0.001) or death (P=0.014) compared to NPDR. Cox adjusted hazard ratio for developing all-cause brain impairments was higher for PDR (HR=1.37, 95% CI 1.16-1.61, P<0.001) which was an independent predictor for all-cause brain impairments (OR 1.30, 95% CI 1.04-1.64, P=0.022), epilepsy (OR 2.16, 95% CI 1.05-4.41, P=0.035) and mortality (HR=1.35, 95% CI 1.06-1.70, P=0.014). CONCLUSIONS: This is the first study to confirm that angiography-proven microvasculopathy identifies patients at high risk for neuropsychiatric morbidity and mortality.
