Background: Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] ³ 50 kg/m²) are scarce.

Objectives: To compare perioperative morbidity and long-term outcomes between patients with SO and non-SO (NSO).

Methods: Patients with SO who underwent primary bariatric surgery with a follow-up ³ 5 years were age- and gender-matched with NSO patients in a retrospective, case-control study. Data included demographics, BMI, co-morbidities, early outcomes, current and nadir weight, co-morbidity status, and general satisfaction.

Results: Of 178 patients, 49.4% were male, mean age 44.5 ± 14 years. Mean preoperative BMI was 54.7 ± 3.6 and 41.8 ± 3.8 kg/m² in SO and NSO, respectively (P = 0.02). Groups were similar in preoperative characteristics. Depression/anxiety was more prevalent in NSO (12.4% vs. 3.4%, P = 0.03). Obstructive sleep apnea was higher in SO (21.3% vs. 10.1%, P = 0.04). Sleeve gastrectomy was performed most often (80.9%), with a tendency toward bypass in SO (P = 0.05). Early complication rates were: 13.5% in SO and 12.4% in NSO (P = 0.82). Mean follow-up was 80.4 ± 13.3 months. BMI reduction was higher in SO (31.8 ± 5.9 vs. 26.8 ± 4.2 kg/m², P < 0.001) and time to nadir weight was longer (22.1 ± 21.3 vs. 13.0 ± 12.0 months, P = 0.001). Co-morbidity improvement and satisfaction were similar.

Conclusions: Patients with SO benefited from bariatric surgery with reduced BMI and fewer co-morbidities. No added risk of operative complications was found compared to patients with NSO.

Background: Coronary artery bypass grafting (CABG) for primary reperfusion in patients with ST elevation myocardial infarction (STEMI) has largely been superseded byf primary percutaneous coronary intervention (PCI) and is estimated to be performed in ≤ 5% of STEMI cases.

Objectives: To compare early CABG (within 30 days following admission) and primary PCI outcomes following STEMI.

Methods: We analyzed a retrospective cohort of patients hospitalized with acute STEMI for early reperfusion therapy between January 2008 and June 2016. Short- and long-term outcomes were assessed for patients with STEMI undergoing primary PCI vs. early CABG as reperfusion therapy.

Results: The study comprised 1660 STEMI patients, 38 of whom (2.3%) underwent CABG within 30 days of presentation. Unadjusted 30-day mortality was more than twice as high in the CABG group (7.5%) than in the PCI group (3.3%); however, it did not reach statistical significance. Similar results were demonstrated for mortality rates beyond 30 days (22% vs. 14%, P = 0.463). All patients undergoing CABG beyond 72 hours following admission survived past 2 years. Multivariate analysis found no differences between the two groups in long-term mortality risk. propensity score matched long-term mortality comparison (30 days–2 years) yielded a 22% mortality rate in the CABG groups compared with 14% in the PCI group (P < 0.293).

Conclusion: Early CABG was performed in only a minority of STEMI patients. This high-risk patient population demonstrated worse outcomes compared to patients undergoing PCI. Performing surgery beyond 72 hours following admission may be associated with lower risk.

Background: Current guidelines for choosing between revascularization modalities may not be appropriate for young patients.

Objectives: To compare outcomes and guide treatment options for patients < 40 years of age, who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) between 2008 and 2018.

Methods: Outcomes were compared for 183 consecutive patients aged < 40 years who underwent PCI or CABG between 2008 and 2018, Outcomes were compared as time to first event and as cumulative events for non-fatal outcomes.

Results: Mean patient age was 36.3 years and 96% were male. Risk factors were similar for both groups. Drug eluting stents were implemented in 71% of PCI patients and total arterial revascularization in 74% of CABG patients. During a median follow-up of 6.5 years, 16 patients (8.6%) died. First cardiovascular events occurred in 35 (38.8%) of the PCI group vs. 29 (31.1%) of the CABG group (log rank P = 0.022), repeat events occurred in 96 vs. 51 (P < 0.01), respectively. After multivariate adjustment, CABG was associated with a significantly reduced risk for first adverse event (hazard ratio [HR] 0.305, P < 0.01) caused by a reduction in repeat revascularization. CABG was also associated with a reduction in overall repeat events (HR 0.293, P < 0.01). There was no difference in overall mortality between CABG and PCI.

Conclusions: Young patients with coronary disease treated by CABG showed a reduction in the risk for non-fatal cardiac events. Mortality was similar with CABG and PCI.

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: Cardiac damage caused by oncological therapy may manifest early or many years after the exposure.

Objectives: To determine the differences between sub-acute and late-onset cardiotoxicity in left ventricular ejection fraction (LVEF) recovery as well as long-term prognosis.

Methods: We studied 91 patients diagnosed with impaired systolic function and previous exposure to oncological therapy. The study population was divided according to sub-acute (from 2 weeks to ≤ 1 year) and late-onset (> 1 year) presentation cardiotoxicity. Recovery of LVEF of at least 50% was defined as the primary end point and total mortality was the secondary end point.

Results: Fifty-three (58%) patients were classified as sub-acute, while 38 (42%) were defined as late-onset cardiotoxicity. Baseline clinical characteristics were similar in the two groups. The mean LVEF at presentation was significantly lower among patients in the late-onset vs. sub-acute group (28% vs. 37%, respectively, P < 0.001). Independent predictors of LVEF recovery were trastuzumab therapy and a higher baseline LVEF. Although long-term mortality rates were similar in the groups with sub-acute and late-onset cardiotoxicity, improvement of LVEF was independently associated with reduced mortality.

Conclusions: Our findings suggest that early detection and treatment of oncological cardiotoxicity play an important role in LVEF recovery and long-term prognosis.

Background: The estimated incidence of esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is 1:3500 live births. During childhood these patients have various co-morbidities, but the overall quality of life among adults is similar to that of the general population.

Objectives: To evaluate short- and long-term co-morbidities and quality of life among infants born with EA ± TEF at a large single medical center.

Methods: Medical records of 65 children born over a 21 year period were reviewed for short- and long-term medical data. Telephone interviews were conducted with 46 of their parents regarding medical problems and quality of life after home discharge.

Results: The main long-term co-morbidities during the first 2 years of life, 4–6 years of age, and during adolescence (12–16 years) included gastro-esophageal reflux disease (GERD) in 56.5%, 35.8%, and 18.7%, respectively; stridor in 84.8%, 45.2%, and 12.5%, respectively; hyper-reactive airway disease (HRAD) in 43.5%, 35.5%, and 36.5%, respectively; recurrent pneumonia in 43.5%, 32.3%, and 18.8%, respectively; and overall recurrent hospitalizations in 87%, 41.9%, and 25%, respectively. The quality of life was reportedly affected among 100%, 75%, and 33.3% respectively.

Conclusions: Long-term follow-up of patients with EA ± TEF indicates a high burden of co-morbidities during the first 6 years of life, with a gradual decrease in symptoms thereafter. Nevertheless, HRAD continued to impact the daily life of about one-third of the older adolescents, and GERD one-fifth. A long-term multidisciplinary follow-up should be conducted to prevent late onset complications that may affect the quality of life.

Background: The long-term significance of apparent life-threatening events (ALTE) has not been thoroughly studied. 

Objectives: To evaluate, at age 5 years, the health status of consecutive children diagnosed with ALTE in infancy. 

Methods: Based on the diagnostic workup, patients were classified into two groups: a ‘broad’ evaluation group (at least one test/procedure related to each of the five main causes: infectious, metabolic, cardiopulmonary, gastroenterological, neurological), and a ‘narrow’ workup group whose evaluation did not cover all five domains. Health status around age 5 was obtained from hospital records, community clinics and parents/caregivers.

Results: We identified 132 children with ALTE. Choking (49.2%) was the most common description, followed by apnea (13.6%), suspected seizure (12.9%), cyanosis (12.1%), breath-holding spell (8.3%), and pallor (3.8%). A broad diagnostic workup was performed in 62.1% of the infants, and a narrow workup in 37.9%. At age 5 years, 56.8% of the children were healthy; 27.3% reported chronic conditions unrelated to ALTE. Twenty-one children (15.9%) had unrelated neurodevelopmental conditions, mostly attention deficit disorder. One of the 132 ALTE patients relapsed and was eventually diagnosed with epilepsy.

Conclusions: A single episode of ALTE in infancy was neither predictive of nor associated with chronic systemic or neurological disease at age 5 years. 

 

Background: The surgical treatment of hip fractures remains controversial especially when considering age. 

Objectives: To investigate the long-term functional outcomes of displaced subcapital hip fractures that were reduced and surgically fixed using parallel cannulated screws in patients aged 60 years and younger. 

Methods: During the period 1996–2005, 27 patients under age 60 with displaced subcapital hip fractures classified as Garden III or IV were treated with fracture reduction and surgical internal fixation using cannulated screws. Patient outcomes were assessed using the Harris Hip Score (HHS) and physical examination.

Results: During a follow-up period of 8–17 years 4 of the 27 patients (14.8%) developed non-union/femoral head avascular necrosis and had undergone hip arthroplasty. All reoperations were performed within the first year after fracture fixation, all in the 50–60 year old age group. The revision rate among patients 50–60 years old was significantly higher than that of patients 50 years and younger (40% vs. 0%, P = 0.037). Mean HHS was higher for patients not requiring revision surgery (85.4) than for patients with revision surgery (75.5), but this difference was not significant.

Conclusions: Internal fixation using fracture reduction and cannulated screw fixation is a successful treatment modality for displaced subcapital hip fractures in patients younger than 50 years old. Patients aged 50–60 years may have a higher risk of avascular necrosis or non-union and require arthroplasty, often within the first year after fracture fixation. The long-term outcome following these fractures is good when excluding patients who had early complications.

 

Background: Appropriate antibiotic use is of both clinical and economic significance to any health system and should be given adequate attention. Prior to this study, no in-depth information was available on antibiotic use patterns in the emergency department of Hadassah Medical Center.

Objectives: To describe the use and misuse of antibiotics and their associated costs in the emergency department of Hadassah Medical Center.

Methods: We analyzed the charts of 657 discharged patients and 45 admitted patients who received antibiotics in Hadassah Medical Center’s emergency department during a 6 week period (29 April – 11 June 2007). A prescription was considered appropriate or inappropriate if the choice of antibiotic, dose and duration by the prescribing physician after diagnosis was considered suitable or wrong by the infectious diseases consultant evaluating the prescriptions according to Kunin’s criteria.

Results: The overall prescribing rate of antibiotics was 14.5% (702/4830) of which 42% were broad- spectrum antibiotics. The evaluated antibiotic prescriptions numbered 1105 (96 prescriptions containing 2 antibiotics, 2 prescriptions containing 3 antibiotics), and 54% of them were considered appropriate. The total inappropriate cost was 3583 NIS[1] (1109 USD PPP[2]) out of the total antibiotic costs of 27,300 NIS (8452 USD PPP). The annual total antibiotic cost was 237,510 NIS (73,532 USD PPP) and the annual total inappropriate cost was 31,172 NIS (9648 USD PPP). The mean costs of inappropriate prescriptions were highest for respiratory (112 NIS, 35 USD PPP) and urinary tract infection (93 NIS, 29 USD PPP). There were more cases when the optimal cost was lower than the actual cost (N=171) than when optimal cost was higher than the actual cost (N=9). In the first case, the total inappropriate costs were 3805 NIS (1,178 USD PPP), and in the second case, -222 NIS (68.7 USD PPP).

Conclusions: The use of antibiotics in emergency departments should be monitored, especially in severely ill patients who require broad-spectrum antibiotics and for antibiotics otherwise restricted in the hospital wards. Our findings indicate that 12% of the total antibiotic costs could have been avoided if all prescriptions were optimal.

Background: Little is known of the outcome of pregnant patients with previously diagnosed dilated cardiomyopathy. These patients are usually firmly advised against continuation of the pregnancy.

Objectives: To examine the usefulness of serial echocardiographic follow-up and plasma N-terminal pro-B type natriuretic peptide levels in the management of pregnant women with preexisting DCM[1].

Methods: We prospectively enrolled pregnant women with DCM either known or diagnosed in the first trimester. Clinical examination and serial echocardiography studies at baseline, 30 weeks gestation, peripartum, and 3 and 18 months postpartum were performed. Blinded NTproBNP[2] levels were obtained at 30 weeks, delivery and 3 months postpartum.

Results: Between June 2005 and October 2006 we enrolled seven women who fulfilled the study criteria. Delivery and postpartum were complicated in 3 patients (42%): 2 with acute heart failure, which resolved conservatively, and 1 with major pulmonary embolism. The left ventricular ejection fraction was stable throughout the pregnancy (35% ± 2.8 at baseline, 33% ± 2.9 at 30 weeks) and postpartum (35% ± 2.8 at 1 day, 34% ± 3.1 at 90 days). Similar stable behavior was observed regarding left ventricular dimensions: LV[3] end-systolic diameters 43.3 ± 2.7 mm and LV end-diastolic diameters 57.3 ± 3.3 mm at baseline compared with 44.1 ± 3.1 mm and 58.7 ± 3.1 mm postpartum, respectively. The NT-ProBNP levels rose significantly peripartum in all three patients with complications.

Conclusions: Serial NT-proBNP levels, as compared to echocardiography, may be a better clinical tool in monitoring and management of pregnant women with preexisting DCM. An early rise in NT-ProBNP level appears to predict the occurrence of adverse events.

Background: Left ventricular outflow gradient is associated with increased morbidity and mortality in hypertrophic cardiomyopathy. Alcohol septal ablation is the alternative to surgery in cases refractory to drug therapy. The implication of LVOG[1] measured 1 week post-ASA[2] for prediction of outcome is unknown.

Objective: To observe the pattern of LVOG course and prediction of long-term clinical and hemodynamic outcome of ASA.

Methods: Baseline clinical and echocardiographic parameters were prospectively recorded in 14 consecutive patients with a first ASA, at the time of ASA, 3 and 7 days after ASA (in-hospital) and 3 and ≥ 12 months after ASA (last follow-up).

Results: There was improvement in NYHA class, exercise parameters and LVOG in 11 of 14 patients (P < 0.005 in all). Maximal creatine kinase level was lower than 500 U/L in those without such improvement and 850 U/L or higher in successful cases. LVOG dropped from 79 ± 30 to 19 ± 6 mmHg after the ASA. LVOG was 50 ± 21 mmHg on day 3, 39 ± 26 on day 7, 32 ± 26 at 3 months and 24 ± 20 mmHg at last follow-up. LVOG identified 27% sustained procedural successes on day 3 and 73% on day 7. The overall predictive accuracy of the test for sustained success and failure was 36% on day 3 and 71% on day 7. Combination of maximal CK[3] and LVOG on day 7 showed four distinct outcome patterns: "early success" with low LVOG and high CK (73% of successful cases), "late success" with high LVOG and high CK, and "early failure" and "late failure" with both low CK and high or low LVOG, respectively
Conclusion: LVOG measurement 7 days post-ASA combined with maximal CK levels predicts late procedural outcome in the majority of patients

Objectives: To evaluate operative procedures, complications, early and late results and long-term functional outcome in FAP[1] patients operated in our department.

Methods: The study group included all patients with FAP who were operated between 1988 and 2003. Demographic data, length of follow‑up, complications, colorectal cancer, pouch function and extracolonic manifestations were recorded.

Results: Median age at surgery was 33 years (range 13–61 years). The final operative breakdown was: 48 proctocolectomies, 41 ileal pouch-anal anastomoses, 2 Kock’s pouch, 5 permanent ileostomies, and 2 colectomies with ileorectal anastomosis. There was no perioperative mortality. Early and late complications occurred in 20 and 9 patients, respectively. Twelve patients required re‑operation. Colorectal carcinoma was diagnosed in eight patients, three of whom were in an advanced stage. The mean follow‑up was 74 months (range 3–288 months). Four patients were lost to follow‑up. Extracolonic manifestations developed in 38 patients, including desmoid tumors (in 12), duodenal adenomas (in 9), pouch adenomas (in 5), and rectal stump adenomas (in 3). Two patients died (4%) because of desmoid tumor and malignant fibrous histiocytoma. At last follow‑up, 37 IPAA[2] patients have (median) six bowel movements/24 hours and good fecal control.

Conclusions: Restorative proctocolectomy can be performed with low mortality, acceptable morbidity, and good functional results. Patients should be closely followed after surgery for development of other manifestations of the syndrome. Relatives of the affected patients should be referred to a specialist multidisciplinary clinic.

Background: Restorative proctocolectomy eliminates the risk of colorectal cancer in patients with familial adenomatous polyposis. Complications and extra‑intestinal manifestations are inherent to the procedure.

Objectives: To evaluate operative procedures, complications, early and late results and long-term functional outcome in FAP[1] patients operated in our department.

Methods: The study group included all patients with FAP who were operated between 1988 and 2003. Demographic data, length of follow‑up, complications, colorectal cancer, pouch function and extracolonic manifestations were recorded.
