Background: Type 2 diabetes mellitus is a multifactorial disease in which genetic susceptibility and environmental factors induce pancreatic β-cell dysfunction and insulin resistance. Additional factors such as hyperglycemia and hyperlipidemia have roles in β-cell dysfunction and disease progression. The phenomenon of lipid-induced pancreatic β-dysfunction, designated as lipotoxicity, has been observed in several in vitro and in vivo experiments; however, there is still no solid evidence for the occurrence of this event in humans. The toxic effect of high lipid levels on β-cell function consists of impaired insulin gene expression, apoptosis, and reduced glucose-stimulated insulin secretion.

Objectives: To demonstrate the importance of treating hypertriglyceridemia in reducing glucose intolerance and the need for insulin therapy in hospitalized diabetic patients.

Methods: We evaluated five clinical case reports and conducted a detailed literature review via the PubMed search engine.

Results: Reduction in elevated blood triglyceride and glucose levels in hospitalized diabetic patients resulted in a rapid decline in glucose levels and in the need for insulin therapy.

Conclusions: A decrease in high triglyceride levels in “lipotoxic” diabetic patients may improve insulin intolerance and glucose homeostasis and reduce the need for insulin therapy.

Background: The treatment of advanced dementia patients is very complex and presents a difficult dilemma for physicians, and especially for the patient's family. In many cases, when the advanced dementia patient has no decisional capacity, the family needs to decide about force-feeding and resuscitation for their relative.

Objectives: To examine public opinion regarding force-feeding and resuscitation of patients with advanced dementia.

Methods: Data from 1002 people who accompanied a patient to a hospital emergency department in Israel were collected and analyzed.

Results: We noted the following results: the more religious the orientation of the respondents, the more likely they were to agree to forcefully feed and resuscitate advanced dementia patients and advanced dementia patients older than 80 years; those accompanying younger patients were more likely to think that the medical staff should resuscitate advanced dementia patients and advanced dementia patients older than 80 years compared to those accompanying elderly patients; younger people were more likely than older people to agree to force-feed and resuscitate patients.

Conclusions: This paper attempts to provide decision-makers and medical staff with some knowledge about public opinion regarding a sensitive and complex issue. This awareness may guide physicians in making critical medical decisions about those with dementia.

Background: Recent studies have analyzed risk factors associated with complications after gastric cancer surgery using the Clavien-Dindo classification (CD). However, they have been based on Asian population cohorts (Chinese, Japanese, Korean).

Objectives: To prospectively analyze all post-gastrectomy complications according to severity using CD classification and identify postoperative risk factors and complications.

Methods: We analyzed all gastrectomies for gastric cancer performed 2009–2014. Recorded parameters included demographic data, existing co-morbidities, neo-adjuvant treatment, intra-operative findings, postoperative course, and histologic findings. Postoperative complications were graded using CD classification.

Results: The study comprised 112 patients who underwent gastrectomy. Mean age was 64.8 ± 12.8 years; 53 patients (47%) underwent gastrectomy, 37 (34%) total gastrectomy, and 22 (19%) total extended gastrectomy. All patients had D2 lymphadenectomy. The average number of retrieved lymph nodes was 35 ± 17. Severe complication rate (≥ IIIa) was 14% and mortality rate was 1.8%. In a univariate analysis, age > 65 years; ASA 3 or higher; chronic renal failure; multi-organ resection; and tumor, node, and metastases (TNM) stage ≥ IIIc were found to be significantly associated with CD complication grade > III (P = 0.01, P = 0.05, P = 0.04, P = 0.04, and P = 0.01, respectively). Multivariate regression analysis revealed advanced stage (≥ IIIc) and age > 65 years to be significant independent risk factors (P < 0.05).

Conclusions: Age > 65 and advanced stage (≥ IIIc) were the primary risk factors for complications of grade > III according to the CD classification following gastrectomy for gastric cancer.

Background: The recommendation of the U.S. Centers for Disease Control and Prevention regarding universal screening for Group B Streptococcus (GBS) at 35–37 weeks gestational age in pregnancy is not accepted in Israel. The National Council for Obstetrics, Neonatology and Genetics recommends intrapartum prophylaxis, mainly based on risk factors, to prevent early neonatal GBS infection. This policy is based on past studies demonstrating low colonization rates of the bacteria in Israeli pregnant women and very low neonatal sepsis rates.

Objectives: To determine the applicability of the high-risk group prophylaxis policy for Arab Israeli pregnant women.

Methods: Vaginorectal swabs from Arab Israeli pregnant women who attended the labor ward between October 2015 and February 2016, were obtained before any pelvic examination for GBS identification using Quidel’s AmpliVue® GBS assay. Women who tested positive received intrapartum antibiotic prophylaxis to prevent neonatal infection. Obstetric data were collected from each woman from a standardized questionnaire. Data regarding the delivery and neonates were collected as well.

Results: The study comprised 188 Arab pregnant women who met the inclusion criteria and signed a consent form to participate in the study. Of these, 59 had positive tests, and a carriage rate of 31%. No neonatal colonization of GBS was found.

Conclusions: The carrier rate in Arab pregnant women in northern Israel is higher than the national average, at least partially due to the more sensitive method of GBS detection used in the present study.

Background: Shortened telomeres were found in patients with cirrhosis, probably reflecting chronic liver injury, continuous regeneration, and destruction of hepatic nodules.

Objectives: To test whether telomere shortening is a general marker of cirrhosis, independent of disease etiology.

Methods: We evaluated telomere length in patients with cryptogenic cirrhosis (largely a late sequela of steatohepatitis) compared to patients with cirrhosis caused by chronic hepatitis B and C (HBV/HCV). We also evaluated telomere aggregates, a sensitive parameter of telomere dysfunction and genetic instability. We analyzed peripheral lymphocytes from 25 patients with cryptogenic cirrhosis, 15 patients with cirrhosis due to chronic viral hepatitis, and 20 age-matched controls. Telomere length was analyzed using quantitative fluorescence in situ hybridization. Aggregate size was divided into three fusion groups of 2–5, 6–10, and 11–15 telomeres, relative to the size of a single telomere.

Results: Shorter telomere length was found in patients with cirrhosis from all three etiologies (mean 121.3 ± 24.1) compared to controls (mean 63.5 ± 23.5). In contrast, there was significantly more fusion of > 5 telomeres only in the HBV/HCV cirrhosis group compared to healthy controls (P = 0.023), but not in the cryptogenic cirrhosis group.

Conclusions: While shortened telomeres in peripheral lymphocytes are a general marker of liver cirrhosis, telomere aggregates may signify a more sensitive genetic instability parameter for the diverse, etiology-based malignant potential of cirrhosis. This finding is in agreement with the well-known higher tendency toward developing hepatocellular carcinoma with cirrhosis caused by chronic hepatitis relative to steatohepatitis.

Background: Damage control laparotomy (DCL) is the widely accepted procedure of choice in management of severely injured trauma patient. It has been implemented in non-trauma-related surgical pathology in the last decade.

Objectives: To evaluate our experience with planned re-laparotomy (PRL) in non-trauma patients and compare it to other reports.

Methods: Charts of all patients admitted to Assaf Harofeh Medical Center who underwent PRL for non-trauma-related abdominal pathology during a 6 year period were reviewed. Data regarding demographics, vital signs, laboratory tests, indications for surgery, length of hospital stay, and mortality were obtained from medical charts. Indications for surgery, risk factors, and mortality were analyzed.

Results: The study was comprised of 181 patients. Primary abdominal sepsis (50), postoperative sepsis (49), mesenteric event (32), and intestinal obstruction (28) were the most common indications for PRL. Mortality rate was 48.6%. Factors correlating with increased mortality were advanced age, hypotension, hypothermia, metabolic acidosis, and renal failure. Bowel resection was performed on 122 patients (67%) and primary intestinal anastomosis constructed in 46.7%. Mortality rate was lower in patients who underwent PRL with primary anastomosis compared to patients with postponed bowel anastomosis (33.3% vs. 55.4%, P = 0.018).

Conclusions: PRL in abdominal emergencies carries a high mortality rate. Primary anastomosis may be considered in non-trauma-related PRL.

Background: Gender-related differences (GRD) exist in the outcome of patients with cardiac resynchronization therapy (CRT).

Objectives: To assess GRD in patients who underwent CRT.

Methods: A retrospective cohort of 178 patients who were implanted with a CRT in a tertiary center 2005–2009 was analyzed. Primary outcome was 1 year mortality. Secondary endpoints were readmission and complication rates.

Results: No statistically significant difference was found in 1 year mortality rates (14.6% males vs. 11.8% females, P = 0.7) or in readmission rate (50.7% vs. 41.2%, P = 0.3). The complication rate was only numerically higher in women (14.7% vs. 5.6%, P = 0.09). Men more often had CRT-defibrillator (CRT-D) implants (63.2% vs. 35.3%, P = 0.003) and had a higher rate of ischemic cardiomyopathy (79.2% vs. 38.2%, P < 0.001). There was a trend to higher incidence of ventricular fibrillation/ventricular tachycardia in men before CRT implantation (29.9% vs. 14.7%, P = 0.07%). A higher proportion of men upgraded from implantable cardioverter defibrillator (ICD) to CRT-D, 20.8% vs. 8.8%, P = 0.047. On multivariate model, chronic renal failure was an independent predictor of 1 year mortality (hazard ratio [HR] 3.6; 95% confidence interval [95%CI] 1.4–9.5), CRT-D had a protective effect compared to CRT-pacemaker (HR 0.3, 95%CI 0.12–0.81).

Conclusions: No GRD was found in 1 year mortality or readmission rates in patients treated with CRT. There was a trend toward a higher complication rate in females. Men were implanted more often with CRT-D and more frequently underwent upgrading of ICD to CRT-D.

Cesarean section has undergone a transformation that has radically changed the prognosis of both the pregnant woman and her unborn child. The attributed mortality rate of Cesarean section during the 19th century was over 50% worldwide. Today, mortality from Cesarean delivery is rare. However, the technique of transversely incising the uterus in its lower uterine segment, although less than a century old, is passed on from instructor to apprentice, often without either of them being aware of its noble history. In this brief review, we discuss the reported history regarding this incision and the significant role played by John Munro Kerr.

The discovery of Jewish babies who were born in Nazi concentration camps and survived seems miraculous, but this phenomenon did occur toward the end of World War II. The lives of a small group of mothers and surviving children are of both historical and medical interests. Their survival shows additional support for the hypothesis that maternal nutrition can induce metabolic syndrome and bone demineralization in their offspring. Information obtained through direct contact with some of the surviving children is the basis for this article.

Aging has been associated with perceived lowering of health, especially in post-traumatic individuals. The effects may be more complex or even different for Holocaust survivors as they age due to their inherited resilience and life perspective. A cross-sectional study was conducted of Holocaust survivors and a matched comparison group recruited from the general Israeli population. All participants underwent a personal interview and completed the Cumulative Illness Rating Scale and a survey of subjective Likert-scale questions about perceived health. The study comprised 214 older adults: 107 Holocaust survivors and 107 comparison participants; 101 women and 113 men. The mean age for the participants was 80.7 ± 4.7 years (range 68–93). Holocaust survivors did not differ from comparison subjects in general health measures (mean 51.50 ± 3.06 vs. 52.27 ± 3.24, respectively). However, the Holocaust survivors' subjective health was significantly lower, F (2,211) = 4.18, P < 0.05, and associated with decreased quality of life. The present study demonstrates the complex interplay between general and subjective health and suggests that future interventions need to focus on improving the psychological and social well-being of Holocaust survivors to achieve successful aging.

Background: Uterine carcinosarcoma (UCS) is a rare tumor with a poor prognosis. An elevated thrombocyte count and thrombocytosis were found to be associated with poor prognosis in several gynecological tumors. Data regarding an elevated thrombocyte count and thrombocytosis, particularly in UCS, are scarce.

Objectives: To assess the frequency of a preoperative elevated thrombocyte count and of thrombocytosis in UCS patients and their association with clinicopathological prognostic factors and survival.

Methods: The preoperative thrombocyte count of 29 consecutive verified USC patients diagnosed in our medical center from January 2000 to July 2015 was recorded, and clinicopathological data of these patients were abstracted from hospital files. 

Results: Thrombocytosis was found in two patients (6.8 %) and both died of the disease. An elevated thrombocyte count was found in nine patients (31.0%). The percentage of patients with the poor prognostic factors who had a preoperative elevated thrombocyte count was not statistically different from those without these risk factors. The cumulative survival of patients with an elevated count was 22.1 months and that of those without an elevated count was 31.1 months. This difference was statistically not significant (P = 0.85). There was also no difference between the groups regarding the progression free survival.

Conclusions: No association between an elevated thrombocyte count and prognosis was found. Larger studies are needed to clarify this issue.
