Background: Sepsis is a common cause of hospitalization, particularly in intensive care units (ICUs), and is a major cause of morbidity and mortality. Diagnosis is often difficult due to the absence of characteristic clinical signs (e.g., fever and leukocytosis); therefore, additional markers, in addition to C-reactive protein (CRP) and white blood cell (WBC) count, are needed.

Objectives: To prospectively link resting energy expenditure (REE) with CRP, WBC count, and sequential organ failure assessment (SOFA) scores in ICU patients. Such a correlation may suggest REE measurement as an additional parameter for sepsis diagnosis.

Methods: Our study comprised 41 ventilated consecutive patients > 18 years of age. Patient demographic data, height, actual body weight, and SOFA scores were collected at admission. REE was measured by indirect calorimetry. REE, CRP, and WBC measurements were collected at admission, on day three after admission, and 1 week later or as clinically indicated.

Results: Comparison of the REE and CRP changes revealed a significant correlation between REE and CRP changes (r = 0.422, P = 0.007). In addition, CRP changes also correlated with the changes in REE (r = 0.36, P = 0.02). Although no significant correlations in REE, WBC count, and SOFA score were found, a significant trend was observed.

Conclusions: To the best of our knowledge, this is the first study to link REE and CRP levels, indicative of severe infection. Further study is needed to establish these findings.

Background: With advances in myelodysplastic syndromes (MDS), patient cohorts from different time periods might be different.

Objectives: To compare presentation and outcomes between two cohorts.

Methods: Data were collected from George Washington University Medical Center, Washington, DC, USA 1986–1987 (DC), and Tel Aviv Medical Center, Israel 1999–2009 (TA).

Results: The study comprised 227 patients (139 TA, 88 DC). TA patients were older (75.4 ± 9.8 vs. 63.8 ± 14.3 years, P < 0.001) and had more cardiovascular diseases (56.8% vs. 14.8%, P < 0.001), fewer cytopenias (1.67 ± 0.82 vs. 2.0 ± 0.93, P = 0.003), and lower mean corpuscular volume (94.3 ± 9.9 fl vs. 100.5 ± 15.3 fl, P < 0.001). Hemoglobin, leukocyte, neutrophil, and platelet counts were similar. More TA patients had dysplasias. Bone marrow cellularity and cytogenetics were similar, but more TA patients had blasts < 5% (73.4% vs. 50.6%, P = 0.003). More TA patients had early French-American-British (FAB) disease (66.9% vs. 40.9%, P < 0.001) and lower risk disease per International Prognostic Scoring System (81% vs. 50%, P < 0.001). The 5 year survival (5YS) of TA patients was not significantly greater (62% vs. 55%). 5YS by FAB was also slightly greater for TA patients (77% vs. 65% for early FAB; 43% vs. 37% for advanced FAB, P > 0.05).

Conclusions: Although patients diagnosed with MDS at a later period were older and had more cardiovascular co-morbidities, they had fewer cytopenias, tended to have earlier disease, and had minimally greater, but not significant, 5YS.

Background: Contemporary data on clinical profiles and long-term outcomes of young adults with coronary artery disease (CAD) are limited.

Objectives: To determine the risk profile, presentation, and outcomes of young adults undergoing coronary angiography.

Methods: A retrospective analysis (2000–2017) of patients aged ≤ 35 years undergoing angiography for evaluation and/or treatment of CAD was conducted.

Results: Coronary angiography was performed in 108 patients (88% males): 67 acute coronary syndrome (ACS) and 41 non-ACS chest pain syndromes. Risk factors were similar: dyslipidemia (69%), positive family history (64%), smoking (61%), obesity (39%), hypertension (32%), and diabetes (22%). Eight of the ACS patients (12%) and 29 of the non-ACS (71%) had normal coronary arteries without subsequent cardiac events. Of the 71 with angiographic evidence of CAD, long-term outcomes (114 ± 60 months) were similar in ACS compared to non-ACS presentations: revascularization 41% vs. 58%, myocardial infarction 32% vs. 33%, and all-cause death 8.5% vs. 8.3%. Familial hypercholesterolemia (FH) was diagnosed in 25% of those with CAD, with higher rates of myocardial infarction (adjusted hazard ratio [HR] 2.62, 95% confidence interval [95%CI] 1.15–5.99) and revascularization (HR 4.30, 95%CI 2.01–9.18) during follow-up. Only 17% of patients with CAD attained a low-density lipoprotein cholesterol treatment goal < 70 mg/dl.

Conclusions: CAD in young adults is associated with marked burden of traditional risk factors and high rates of future adverse cardiac events, regardless of acuity of presentation, especially in patients with FH, emphasizing the importance of detecting cardiovascular risk factors and addressing atherosclerosis at young age.

Background: Unlike the elective treatment of metastatic colorectal cancer (MCRC), sufficient data and consensual guidelines on acute care are lacking.

Objectives: To analyze a cohort of MCRC patients who required urgent surgery due to acute abdomen and to identify risk factors contributing to the patient's perioperative mortality and morbidity.

Methods: A retrospective analysis was conducted of patients diagnosed with stage IV colorectal cancer who required urgent laparotomy at the Rabin Medical Center. Comparative analysis was performed using Pearson’s chi-square and Student`s t-test.

Results: Between 2010 and 2015, 113 patients underwent urgent laparotomy due to colorectal cancer complications, of which 62 patients were found to have a metastatic, stage IV, disease. Large bowel obstruction was the most common indication for urgent laparotomy. In-hospital mortality was 30% (n=19), and overall 30 day mortality was 43%. Fifteen patients (24%) required more than one surgery. The average length of hospital stay was 21 days. Age and lactate levels at presentation were the only prognostic factor found for mortality (P < 0.05).

Conclusions: MCRC laparotomy patients incur a significant burden of care and have a relatively high incidence of early mortality. Our data suggest high, verging on unacceptable, mortality and complication rates in this subgroup of patients. This finding is further accentuated in the subgroup of older patients presenting with lactatemia. These data should be considered by surgeons when discussing treatment options with patients and families.

Background: Leukoplakia of the vocal cords may represent a pre-cancerous lesion of the larynx. The management of cases of recurrent leukoplakia with pathologically proven dysplasia is still controversial.

Objectives: To present a series of patients with recurrent vocal cord leukoplakia and to examine their malignant transformation rate in relation to the clinical characteristics, risk factors, and histological findings.

Methods: A retrospective cohort study was conducted between 1999 and 2017. The study comprised 52 patients with recurrent leukoplakia of the vocal cords who required ≥ 2 direct laryngeal procedures within a minimum of 3 months between each procedure. Malignant transformation rate over follow-up period, risk factors for malignant transformation, and interval to develop laryngeal squamous cell carcinoma were investigated.

Results: All patients presented with hoarseness. An average of three procedures per patient was performed (range 2–13). Ten male patients (19.2%) developed squamous cell carcinoma. Of these, four with severe dysplasia developed SCC within 19 months of the first direct laryngoscopy. In the six other patients, SCC developed within an average of 3.7 years. The follow-up period ranged from 9–253 months (mean 109 months). Heavy smoking and severe dysplasia in the first biopsy were found to be significant risk factors for developing squamous cell carcinoma, as was male gender.

Conclusions: We showed an increased malignant transformation rate in recurrent leukoplakia cases among heavy smokers and male patients. In addition, severe dysplasia at initial diagnosis was a risk factor for SCC development. Close follow-up of patients with recurrent leukoplakia is warranted.

Background: Almost 50% of patients with germ-cell tumors (GCT) are subfertile, and every step of the treatment may further impair fertility. As a result, sperm banking is often advised prior to radical orchiectomy. However, whether affected testes contribute to fertility is unclear.

Objectives: To determine whether maximal tumor diameter (MTD) is correlated with ipsilateral fertility (IF) in patients treated for GCT.

Methods: We reviewed medical charts for demographic and clinical data of patients with GCT who had undergone orchiectomy at our institution between 1999 and 2015. The extent of spermatogenesis was categorized into three groups: full spermatogenesis, hypospermatogenesis, and absence of spermatogenesis. The presence of mature spermatozoa in the epididymis tail was also assessed. We defined IF as the combination of full spermatogenesis in more than 100 tubules and the presence of mature spermatozoa in the epididymis tail. Mann–Whitney was applied to determine the correlation between MTD and IF.

Results: Of 57 patients, IF was present in 28 (49%). Mean patient age was 32.8 years in patients with positive IF and 33.4 years those with negative IF. Seminoma was diagnosed in 46.4% of patients with positive IF and in 65.5% of patients with negative IF. Full spermatogenesis was observed in 33 patients (57.8%). In 48 (82.7%), mature epididymal spermatozoa were found. No correlation was found between MTD and IF.

Conclusions: IF is present in almost half of the patients undergoing radical orchiectomy. Because IF cannot be predicted by MTD, routine pre-orchiectomy sperm banking is suggested.

Background: Magnesium is an essential intracellular cation. Magnesium deficiency is common in the general population and its prevalence among patients with cirrhosis is even higher. Correlation between serum levels and total body content is poor because most magnesium is intracellular. Minimal hepatic encephalopathy is a subclinical phase of hepatic encephalopathy with no overt symptoms. Cognitive exams can reveal minor changes in coordination, attention, and visuomotor function, whereas language and verbal intelligence are usually relatively spared.

Objectives: To assess the correlation between intracellular and serum magnesium levels and minimal hepatic encephalopathy.

Methods: Outpatients with a diagnosis of compensated liver cirrhosis were enrolled in this randomized, double-blinded study. Patients were recruited for the study from November 2013 to January 2014, and were randomly assigned to a control (placebo) or an interventional (treated with magnesium oxide) group. Serum and intracellular magnesium levels were measured at enrollment and at the end of the study. Cognitive function was assessed by a specialized occupational therapist.

Results: Forty-two patients met the inclusion criteria, 29 of whom were included in this study. Among these, 83% had abnormal cognitive exam results compatible with minimal hepatic encephalopathy. While only 10% had hypomagnesemia, 33.3% had low levels of intracellular magnesium. Initial intracellular and serum magnesium levels positively correlated with cognitive performance.

Conclusions: Magnesium deficiency is common among patients with compensated liver cirrhosis. We found an association between magnesium deficiency and impairment in several cognitive function tests. This finding suggests involvement of magnesium in the pathophysiology of minimal hepatic encephalopathy.
