Background: Standardization of the dietetic care process allows for early identification of malnutrition and metabolic disorders, interdisciplinary collaboration among the medical team, and improved quality of patient care. Globally, dietitians are adopting a nutrition care model that integrates national regulations with professional scope of practice. Currently, Israel lacks a standardized dietetic care process and documentation terminology.

Objectives: To assess the utilization of a novel sectoral documentation system for nutrition care in Israel.

Methods: Seventy dietitians working in 63 geriatric facilities completed an online training program presenting the proposed patient-sectoral-model. Training was followed by submission of sample case studies from clinical practice or completion of a case simulation. Application of the proposed model was assessed by measuring the frequency participants implemented different sections of the model and responses to an approval questionnaire.

Results: Fifty-four participants (77%) provided completed cases. Over 80% of participants reported each step of the proposed dietary care process with 100% reporting the “nutrition diagnosis”. Fifty-one dietitians (72.8%) completed the approval survey with the section on nutrition diagnosis receiving a highly favorable response (95%), indicating that the new documentation system was beneficial. Over 80% of participants rated the model useful in clinical practice.

Conclusions: A sectoral approach for documenting dietetic care may be the ideal model for dietitians working in specific patient populations with the potential for improving interdisciplinary collaboration in patient care.

Background: Biallelic BLM gene mutation carriers are at an increased risk for cancer, including colorectal cancer (CRC). Whether heterozygous BLM gene mutations confer an increased cancer risk remains controversial.

Objectives: To evaluate CRC and endometrial cancer risk in BLM heterozygous mutation carriers.

Methods: Jewish Ashkenazim at high risk for colon or endometrial cancer and endometrial cancer cases unselected for family history were genotyped for the BLM^Ash predominant mutation.

Results: Overall, 243 high-risk individuals were included: 97 men CRC patients (55.12 ± 12.3 years at diagnosis), 109 women with CRC (56.5 ± 13.7 years), 32 women with endometrial cancer (58.25 ± 13.4 years) and 5 women with both CRC and endometrial cancer. In addition, 120 unselected Ashkenazi women with endometrial cancer (64.2 ± 11.58 years) were genotyped. The BLM^Ash mutation was present in 4/243 (1.65%) high-risk patients; 2 CRC (0.97%) 2 endometrial cancer (5.4%), and 1/120 unselected endometrial cancer patients (0.84%). Notably, in high-risk cases, BLM^Ash mutation carriers were diagnosed at a younger age (for CRC 47.5 ± 7.8 years; P = 0.32 ; endometrial cancer 49.5 ± 7.7 years; P = 0.36) compared with non-carriers.

Conclusions: Ashkenazi high risk CRC/endometrial cancer, and women with endometrial cancer have a higher rate of BLM^Ash heterozygous mutation compared with the general population. BLM^Ash heterozygous mutation carriers are diagnosed with CRC and endometrial cancer at a younger age compared with non-carriers. These observations should be validated and the possible clinical implications assessed.

Background: neonatal cardiac surgery has evolved over the last 50 years with a large percentage of the patients achieving complete physiological repair in the neonatal period. The remaining patients achieve staged palliation with an increasing amount of success. 

Objectives: To report our experience with 1000 neonatal cardiac surgical procedures performed in the last 10 years.

Methods: We conducted a retrospective analysis of surgical outcome in all neonatal patients who underwent cardiac surgery between January 2007 and July 2016 at Schneider Children's Medical Center of Israel.

Results: A total of 1003 neonates aged < 30 days underwent surgery for congenital heart defects at our center. Neonatal surgery accounted for 22.5% of all cardiac surgeries. Neonatal operative mortality was 7.3%, Operative mortality for individual lesions were: simple aortic coarctation (CoA) (198 patients, 2.5%), CoA with hypoplastic arch (24, 4%), CoA with ventricular septal defect (VSD) (84, 2.3%), transposition of the great arteries (TGA, simple and complex, 185, 6.3%), TGA with VSD (37, 0%), truncus arteriosus (26, 3.8%), interrupted aortic arch (25, 4%), Norwood Sano (71, 19.7%), neonatal tetralogy of Fallot (41, 0%), and shunt (131 patients, 12%).

Conclusions: Neonatal surgical capabilities have improved substantially over the last decades. Excellent results can be expected for lesions that can be repaired to create biventricular circulation. Improved results can be attributed in part to the evolution of surgical strategies and assistive technologies, but essential is the collaborative effort of surgeons, cardiologists, anesthesiologists, and intensive care specialists acting as a cohesive team whose performance far exceeds the sum of its individual members’ contributions. 

 

Abstract

Background: Diabetes mellitus-related lower extremity amputation is a major complication severely affecting patient survival and quality of life.

Objectives: To analyze epidemiological and clinical trends in the incidence and survival of lower extremity amputations among diabetes patients.

Methods: We conducted a retrospective observational cohort study of 565 consecutive diabetes patients who underwent their first non-traumatic lower extremity amputation between January 2002 and December 2009.

Results: Major amputations were performed in 316 (55.9%) patients: 142 above the knee (25.1%) and 174 below (30.8%); 249 (44.1%) had a minor amputation. The incidence rates of amputations decreased from 2.9 to 2.1 per 1000 diabetes patients. Kaplan-Meier survival analysis showed that first year mortality rates were lower among patients with minor amputations (31.7% vs. 39.6%, P = 0.569). First year mortality rates following below-knee amputation were somewhat lower than above-knee amputation (33.1 vs.45.1%, respectively). Cox regression model of survival at 1 year after the procedure found that age (HR 1.06 per year, 95% CI 1.04–1.07, P < 0.001), above-knee amputation (HR 1.36, 95% CI 1.01–1.83, P = 0.045) and ischemic heart disease (HR 1.68, 95% CI 1.26–2.24, P < 0.001) significantly increased one year mortality risk.

Conclusions: In this population-based study the incidence rate of non-traumatic amputations in diabetes patients between January 2002 and December 2009 decreased slightly. However, one year mortality rates after the surgery did not decline and remained high, stressing the need for a multidisciplinary effort to prevent amputations in diabetes patients.

Abstract

Background: Renal hemangiomas are rare benign tumors seldom distinguished from malignant tumors preoperatively.

Objectives: To describe the Memorial Sloan-Kettering Cancer Center (MSKCC) experience with diagnosing and treating renal hemangiomas, and to explore possible clinical and radiologic features that can aid in diagnosing renal hemangiomas preoperatively.

Methods: Patients with renal hemangiomas treated at MSKCC were identified in our prospectively collected renal tumor database. Descriptive statistics were used to describe the patient characteristics and the tumor characteristics. All available preoperative imaging studies were reviewed to assess common findings and explore possible characteristics distinguishing benign hemangiomas from malignant renal tumors preoperatively.

Results: Of 6341 patients in our database 15 were identified. Eleven (73%) were males, median age at diagnosis was 53.3 years, and the affected side was evenly distributed. All but two patients were treated surgically. The mean decrease in estimated glomerular filtration rate (eGFR) after surgery was 36.3%; one patient had an abnormal presurgical eGFR and only two patients had a normal eGFR after surgery. We could not identify radiographic features that would make preoperative diagnosis certain, but we did identify features characteristic of hepatic hemangiomas that were also present in some of the renal hemangiomas.

Conclusions: Most renal hemangiomas cannot be distinguished from other common renal cortical tumors preoperatively. In select cases a renal biopsy can identify this benign lesion and the deleterious effects of extirpative surgery can be avoided.

Objectives: To determine the properties of HAM as an antigenic substrate for the detection of autoantibodies in pemphigus vulgaris and bullous pemphigoid.

Methods: Immunomapping and tandem liquid chromatography mass spectrometry were used to delineate the antigenic structure of HAM in 25 pemphigus patients, 41 pemphigoid patients, and 36 controls. Immunoblotting and indirect immunofluorescence were used to study the diagnostic utility of HAM, and the results were compared to those of indirect immunofluorescence on monkey esophagus, immunoblotting using normal human skin, and enzyme-linked immunosorbent assay (ELISA).

Results: Immunomapping demonstrated the presence of all the antigens known to be targeted in autoimmune bullous skin diseases, in both normal human skin and HAM, except for the absence of BP230, and low threshold levels of Dsg1, Dsg3 and Dsc3 in HAM. HAM indirect immunofluorescence demonstrated anti-basement membrane zone antibodies in 48.7% of the pemphigoid patients, and anti-intercellular space antibodies in 72.0% of the pemphigus patients. HAM immunoblotting did not demonstrate anti-BP230 antibodies, but detected anti-BP180 antibodies in 53.6% of the pemphigoid patients. It did not demonstrate anti-Dsg1 and/or anti-Dsg3 antibodies in any of the pemphigus patients. These results were inferior to those of ELISA and monkey esophagus indirect immunofluorescence.

Conclusions: Compared to other studied methods, HAM does not offer advantages in detecting autoantibodies in bullous pemphigoid and pemphigus vulgaris. 

Objectives: To characterize the clinical features and outcomes of body packers hospitalized at the Sheba Medical Center.

Methods: We conducted a retrospective case series of body packers hospitalized between January 2010 and October 2012 in our medical center. Electronic medical records and imaging files were reviewed to extract clinical, laboratory and radiological data as well as details on medical treatments.

Results: We identified 23 body packers (mean age 38 ± 10 years), 20 of whom smuggled cocaine from South America. The number of packets transported ranged from 1 to 242 (median 42) and duration of hospitalization from 1 to 14 days (median 2). Two subjects required surgical intervention. All others were treated conservatively by polyethylene glycol-electrolyte lavage solution, laxatives, or watchful waiting. Ten patients underwent a urinary screen for illicit drugs, 7 of whom tested positive for cocaine and 2 for cannabinoids. Abdominal X-rays were performed in all patients at admission, and 14 had follow-up imaging, including abdominal CT scans without contrast media in 8.

Conclusions: The main treatment goals for body packers are the rapid excretion of drug packets and early detection of complications, i.e., drug intoxication and bowel obstruction. We suggest the use of a structured treatment approach for the in-hospital management of body packers.

Objectives: To assess whether a new herbal-based potentially wake-promoting beverage is effective in counteracting somnolence and reduced post-lunch performance.

Methods: Thirty healthy volunteers were studied on three different days at the sleep clinic. On each visit they ate a standard lunch at noontime, followed by a drink of "Wake up®," 50 mg caffeine, or a placebo in a cross-over double-blind regimen. At 30 and 120 minutes post-drinking, they underwent a battery of tests to determine the effects of the beverage. These included: a) a subjective assessment of alertness and performance based on a visual analog scale, and b) objective function tests: the immediate word recall test, the digit symbol substitution test (DSST), and hemodynamic measurements. The results of the three visits were compared using one-way analysis of variance, with P < 0.05 considered statistically significant.

Results: In all performance tests, subjective vigilance and effectiveness assessment, both Wake up® and caffeine were significantly superior to placebo 30 minutes after lunch. However, at 2 hours after lunch, performance had deteriorated in those who drank the caffeine-containing drink, while Wake up® was superior to both caffeine and placebo. Blood pressure and pulse were higher 2 hours after caffeine ingestion, compared to both Wake up® and placebo.

Conclusions: These results suggest that a single dose of Wake up® is effective in counteracting the somnolence and reduced performance during the post-lunch hours. In the current study it had no adverse hemodynamic consequences.
