Red Blood Cell Distribution Width (RDW) and long-term survival in patients with ST Elevation Myocardial Infarction

Introduction

High RDW values are associated with adverse prognosis in many clinical conditions including short and medium term outcome of patients with ST Elevation Myocardial Infarction (STEMI). The aim of the present study was to evaluate the association between RDW and long term mortality in STEMI patients undergoing primary angioplasty (PPCI).

Material and methods

A cohort of 535 STEMI patients undergoing PPCI were divided into two groups (RDW > 14%, RDW ≤ 14%) using CHAID and CART methods. The association between RDW and 5-year all-cause mortality was assessed using Cox’s proportional hazards analysis.

Results

A total of 37 patients died during follow up of 5 years (mean: 1059, median: 1013, range 2–2130 days). RDW > 14% was associated with increased risk of all-cause mortality (HR = 5, CI 95% 2.7– 9.9, p < 0.001). In multivariate analysis, RDW > 14 remained significantly associated with increased risk for all-cause mortality (HR = 3.8, CI 95% 1.8– 7.99, p < 0.001). Patients with RDW above 14% did not have lower ejection fraction, higher CPK or more conventional risk factors.

Conclusion

RDW value above 14 is independently associated with increased long term all-cause mortality in patients with STEMI undergoing PPCI.     

Increased serum C-reactive protein levels are associated with shorter survival and development of second cancers in chronic lymphocytic leukemia

Background: Chronic lymphocytic leukemia (CLL) is characterized by a heterogeneous clinical course, ranging from stable to more aggressive disease. Herein, we determined the prognostic significance of serum C-reactive protein (CRP) levels in patients with CLL

Methods: A retrospective cohort study reviewing the records of 107 consecutive treatment naïve patients with CLL and a control group comprised of apparently healthy individuals attending for periodic health examinations.

Results: The median CRP level of patients with CLL was 0.19?mg/dL (0–2.9). In univariate analysis, high-CRP levels (≥0.4 mg/dL) were significantly associated with an increased risk of mortality (HR?=?3.97, 95%CI 1.64–9.62, p?=?.002) and development of second solid cancers (HR?=?4.54, 95%CI 1.57–13.11, p?=?.005), compared to low-CRP values (<0.4 mg/dL). In multivariate analysis, high-CRP retained statistical significance for all-cause mortality (HR?=?2.81, 95%CI 1.04–7.57, p?=?.04) and the development of second solid malignancies (HR?=?4.54, 95%CI 1.57–13.11, p?=?.005). Moreover, when compared to an apparently healthy population, CLL patients with high CRP levels had more than an eightfold risk of cancer.

Conclusions: Elevated baseline CRP levels are associated with shorter survival and development of second cancers in patients with CLL. We suggest that increased CRP in patients with CLL may justify a more rigorous search for second cancers.

• KEY MESSAGES

• Elevated CRP levels are associated with a shorter overall survival in CLL.

• Elevated CRP levels are associated with an increased risk of second cancers in CLL.

• Increased CRP in patients with CLL may justify a more rigorous search for second cancers.

     

Early Enteral Feeding of the Preterm Infant—Delay until Own Mother’s Breastmilk Becomes Available? (Israel, 2012–2017)

Aim: To consider the question of whether to initiate trophic feeds with formula in the absence of own mother’s breastmilk or to wait for breastmilk to be available. Methods: A retrospective study of infants born prior to 32 weeks of gestation during the period 2012–2017 at a single tertiary center in Tel Aviv, Israel. Three TF groups were defined: exclusive breastmilk, mixed, and exclusive formula. Univariate and multivariate analyses were conducted. Logistic regression was used, and adjusted odds ratio and 95% interval were reported. Results: Univariate analysis demonstrated that infants in the exclusive breastmilk group were born earlier, had lower birth weights and lower Apgar scores, were given lower volumes of TF, and were more likely to have a longer hospital stay. Poor composite outcome was more common among the exclusive breastmilk group. Multivariate regression analysis revealed no differences in incidence of early neonatal morbidities between the groups, except for longer duration of parenteral nutrition in the exclusive breastmilk group. Conclusion: In our cohort, exclusive formula TF was not associated with increased risk of any of the studied morbidities. Clinicians should consider this finding in deciding between early TF or fasting while waiting for own mother’s breastmilk.

Anthropometric Assessment of Neck Adipose Tissue and Airway Volume Using Multidetector Computed Tomography: An Imaging Approach and Association With Overall Mortality

Neck adiposity tissue volume (NATV) accumulation is an indicator for metabolic syndrome and cardiovascular disease (CVD). Neck circumference is a poor measure of NATV, and a quantifier for this entity has not yet been established.To evaluate volumetric quantification by multidetector computed tomography (MDCT) as a reproducible anthropometric tool to measure NATV and airway volume (AWV).A total of 519 patients, including a subset of 70 random patients who underwent head and neck CT scanning in our hospital within 1 year (2013), were studied. Included patients were all those undergoing nonenhanced CT (NECT) or CT angiography (CTA). Neck cross-sectional areas (NCSA) were measured at 2 separate levels of the neck, and 3D postprocessing tissue reconstruction was performed, and NATV and AWVs were quantified volumetrically for all patients within the year.The average NCSA at the level of the soft palate and thyroid cartilage was 22,579 and 14,500 mm², respectively. NATV when compared to the upper and lower levels of NCSA showed correlations of 0.64 and 0.79, respectively (P < 0.001). Interobserver analysis showed mean deviations of 0.46% and 0.32% for NATV and AWV, respectively. A strong correlation between NATV and body mass index (BMI) was found (r = 0.658, P < 0.001), and the top quartile of NATV:AWV patients (out of 519 patients) displayed a statistically significant mortality rate during 670 days of follow-up (d = 7.5%, P = 0.032). After adjustment for age and gender, the association between NATV:AWV and mortality was close to significant (P = 0.072).Volumetric quantification of NATV and AWV is a reproducible and prognostic anthropometric tool, as a high NATV:AWV demonstrated a significant risk factor for mortality; future research may further advance our understanding of this phenomenon.     

Medical expertise as a critical influencing factor on the length of stay in the ED: A retrospective cohort study

Overcrowding in the emergency departments (ED) is a significant issue associated with increased morbidity and mortality rates as well as decreased patient satisfaction. Length of stay (LOS) is both a cause and a result of overcrowding. In Israel, as there are few emergency medicine (EM) physicians, the ED team is supplemented with doctors from specialties including internal medicine, general surgery, orthopedics etc. Here we compare ED length of stay (ED-LOS), treatment time and decision time between EM physicians, internists and general surgeons.A retrospective cohort study was conducted examining the Emergency Department length of stay (ED-LOS) for all adult patients attending Sheba Medical Center ED, Israel, between January 1st, and December 31st, 2014. Using electronic medical records, data was gathered on patient age, sex, primary ED physician, diagnosis, eventual disposition, treatment time and disposition decision time. The primary outcome variable was ED-LOS relative to case physician specialty and level (ED, internal medicine or surgery; specialist or resident). Secondary analysis was conducted on time to treatment/ decision as well as ED-LOS relative to patient classification variables (internal medicine vs surgical diagnosis). Specialists were compared to specialists and residents to residents for all outcomes.Residents and specialists in either EM, internal medicine or general surgery attended 57,486 (51.50%) of 111,630 visits to Sheba Hospital''s general ED. Mean ED-LOS was 4.12 ± 3.18 hours. Mean treatment time and decision time were 1.79 ± 1.82 hours, 2.84 ± 2.17 hours respectively. Amongst specialists, ED-LOS was shorter for EM physicians than for internal medicine physicians (mean difference 0.28 hours, 95% CI 0.14–0.43) and general surgeons (mean difference 0.63 hours, 95% CI 0.43–0.83). There was no statistical significance between residents when comparing outcomes.Increasing the number of EM specialists in the ED may support efforts to decrease ED-LOS, overcrowding and medical errors whilst increasing patient satisfaction and outcomes.     

Original research: Important relation between self-efficacy,sense of coherence,illness perceptions,depression and anxiety in patients with inflammatory bowel disease

IntroductionAnxiety and depression are common disturbances in patients with inflammatory bowel diseases (IBD), and were found to impact the disease course. Illness perceptions (IPs), self-efficacy (SE) and sense of coherence (SOC) are important psychological functions, used by the individual to cope with his chronic disease.Aimsto investigate the association of IP, SE and SOC on anxiety and depression among patients with IBD.Patients and methodsPatients filled questionnaires including: demographic, socioeconomic and clinical features. Depression and anxiety were assessed using the Hospital Anxiety and Depression Scale. IP, SE and SOC were assessed using the Brief Illness perception Questionnaire, IBD-SE and SOC scales.ResultsThe study sample consisted of 299 patients with IBD, median age 34.15, 63% females, 70.9% had Crohn’s disease, filled the questionnaires. In the multivariate analysis, lower results in IP, SE and SOC were found to be associated with significantly increase anxiety (OR 8.35, p<0.001; OR 4.18, p=0.001; OR 4.67, p<0.001, respectively) and depression (OR 15.8, p=0.001; OR 10.99, p=0.029; OR 6.12, p=0.014ConclusionsAnxiety and depression are associated with IP, SE and SOC in patients with IBD. Clinicians should be aware of this impact, recognise their patients’ psychological abilities to cope with the disease and improve those abilities, when needed, in order to achieve a better coping with the disease and to prevent the development of anxiety and depression.
