Early safety outcomes of laparoscopic one anastomosis gastric bypass in patients with class III, IV, and V obesity.

Background: The extremely obese patient deserves special consideration: significant comorbidities, technical difficulties, and increased postoperative morbidity and mortality are all expected in this patient population. The study compared early postoperative complications (≤30-day) following one-anastomosis gastric bypass (OAGB) morbidity in patients with morbid obesity class IV obesity, body mass index (BMI) ≥50-59.9 kg/m, and class V obesity, BMI ≥60 patients.

Early outcomes of one-anastomosis gastric bypass in the elderly population at high-volume bariatric centers.

The increasing rate of obesity and life expectancy will lead to increasing numbers of bariatric procedures in the elderly. We aim to report the early (≤ 30 days) adverse events of One-Anastomosis Gastric Bypass (OAGB) in this patient population. Assuta Bariatric Centers in Israel.

One Anastomosis Gastric Bypass in 6722 Patients: Early Outcomes from a Private Hospital Registry.

Background: One-anastomosis gastric bypass (OAGB) is an emerging metabolic bariatric surgery (MBS) type used in both primary OAGB (pOAGB) and revisional OAGB (rOAGB). We studied ≤30-day outcomes of pOAGB and rOAGB and identified predictors of early complications.

Methods: Electronic medical records of all OAGBs performed between January 2017 and December 2021 at a high-volume bariatric clinic in Israel comprising four hospital centers were scanned retrospectively using specialized data software (MDClone software, version 6.

Addressing the important error of missing surgical items in an operated patient.

Background: We aim to analyze the characteristics of incidences of missing surgical items (MSIs) and to examine the changes in MSI events following the implementation of an MSI prevention program.

Methods: All surgical cases registered in our medical center from January 2014 to December 2019 were retrospectively analyzed.

Results: Among 559,910 operations, 154 MSI cases were reported.

Benefit versus risk of chromosomal microarray analysis performed in pregnancies with normal and positive prenatal screening results: A retrospective study.

Background: Most studies on chromosomal microarray analysis (CMA) and amniocentesis risks have not evaluated pregnancies with low risk for genetic diseases; therefore, the efficacy and safety of CMA and amniocentesis in this population are unclear. This study aimed to examine the benefits and risks of prenatal genetic diagnostic tests in pregnancies having low risk for chromosomal diseases.

Methods And Findings: In this retrospective study, we used clinical data from a large database of 30,830 singleton pregnancies at gestational age 16-23 weeks who underwent amniocentesis for karyotyping with or without CMA.

Assessment of hospital disaster plans for conventional mass casualty incidents following terrorist explosions using a live exercise based upon the real data of actual patients.

Purpose: The National Committee for Hospital Preparedness for Conventional Mass Casualty Incidents and the Hospital Preparedness Division of the Home Front Command are in charge of preparing live exercises held yearly in public hospitals in Israel. Our experience is that live exercises are limited in their ability to test clinical decision making and its influence upon incident management. A live exercise was designed upon real patient data and tested in several public hospitals.

Tuberous sclerosis in a military pilot.

Tuberous sclerosis (TS) is a multisystem disorder characterized by hamartomas in various organs. It usually manifests itself during infancy or childhood with neurological features, including mental retardation and seizures. We present the case of a military pilot who was diagnosed with TS at 22 yr.

Sinusitis in pilots of different aircraft types: is allergic rhinitis a predisposing factor?

Background: Despite the high association of allergic rhinitis and acute sinusitis, their exact relationship remains unclear, especially in pilots. The purpose of this study was to analyze the possible relationship of a history of allergic rhinitis with the occurrence of acute sinusitis in Israeli air force pilots. A comparative case series was conducted.

Interventricular septum thickness predicts future systolic hypertension in young healthy pilots.

Left ventricular hypertrophy (LVH) has been associated with hypertension, although debate exists as to whether LVH is caused by elevated blood pressure (BP) or is a risk factor for its development. The present study evaluates the association between left ventricular structure and the development of hypertension in a young healthy population. We followed young healthy Israeli Air Force aviators from initial echocardiography at the start of their military service to a mean of 7.

Posturography as an indicator of fatigue due to sleep deprivation.

Background: Fatigue is one of the main causes for accidents in transportation. This study was designed to assess the efficacy of a short objective posturographic test as an indicator of fatigue due to sleep deprivation.

Objectives: To assess the efficiency of a short objective posturographic test as an indicator of fatigue due to sleep deprivation.

Physical examination and ECG screening in relation to echocardiography findings in young healthy adults.

Background And Aims: Cardiovascular screening in young adults is an important tool in many occupational settings. Our aim was to test whether screening physical examination and ECG influence the rate of abnormal echocardiogarphic findings in young healthy subjects.

Methods: Consecutive echocardiography results of 18- to 20-year-old flight candidates were analyzed retrospectively.

Long-term survivors of childhood malignancies--aeromedical dilemmas and implications.

Survival rates from childhood cancer have dramatically improved over the past three decades; average overall 5-yr survival rates are now > 75%. However, this has been achieved by treatments associated with significant morbidity that may present many years later. This review seeks to delineate the basic information necessary to evaluate flight-training candidates with a history of childhood cancer.

Pre-hypertension as a predictor of hypertension in military aviators: a longitudinal study of 367 men.

Background: Recently, the seventh report of the Joint National Committee on prevention, detection, evaluation, and treatment of high blood pressure introduced the term "pre-hypertension" for systolic blood pressure (BP) levels of 120-139 and diastolic BP levels of 80-89 mmHg. Our aim was to establish the prevalence of this novel entity among young subjects, and to assess the rate of progression to hypertension.

Methods: We retrospectively analyzed the data of a group of 367 male aviators who were examined at the age of 18 and who were followed for an average of 18 +/- 7 yr (range 3-37 yr).

Cervical and lumbar MRI findings in aviators as a function of aircraft type.

Background & Aims: Neck pain and lower back pain (LBP) are frequently reported by military helicopter pilots (HP) and fighter pilots. A small number of studies have used imaging methods to evaluate spinal cervical degenerative findings in pilots exposed to high +Gz, with results indicating an increase in cervical disk protrusions in this population. We evaluated the cervical and lumbar spine with magnetic resonance imaging (MRI) to assess the prevalence of degenerative changes in three subpopulations of pilots.

Evaluation of systemic allergy in a jet aviator.

Cholinergic urticaria and exercise-induced anaphylaxis (EIA) are related conditions. Cholinergic urticaria is caused by a rise in body core temperature and usually results in pruritus, skin lesions and, rarely, in serious respiratory and cardiovascular compromise. EIA can result in a cardiovascular compromise and syncope.

PET scan as an aid for the return of a head-injured aviator to flying duty.

Head injury is not a rare event in aviators, and poses a difficult dilemma for the flight surgeon regarding return to flying duty due to the fear of post-traumatic epilepsy. Positron emission tomography (PET) is a functional neuroimaging modality that provides additional localizing data in epileptic patients in the interictal phase. We describe a case of penetrating head trauma with no loss of consciousness in a military jet fighter pilot in which the magnetic resonance imaging revealed a minimal brain contusion.

Effect of G-force on bicuspid aortic valve in aviators.

Background And Aims: Bicuspid aortic valve (BAV) is a common congenital cardiac malformation. The major complications are aortic stenosis (AS), aortic regurgitation (AR), infectious endocarditis and aortic dissection. This paper aims to assess the hemodynamic importance of incidentally-found BAV in military aviators and evaluate the effect of high G-force on disease progression.

Asthma in military aviators: safe flying is possible.

Introduction: Asthma is considered relatively incompatible with aviation. Firstly, due to the risk of sudden incapacitation, and secondly, due to cold and dry air and other asthmogenic factors characteristic of the aviation environment. The medical requirements for flying fitness of asthmatic aviators are inconsistent between different air services, and many flight surgeons are unfamiliar with the recent developments in asthma management.

Brief posturographic test as an indicator of fatigue.

The purpose of the present paper was to analyze the efficiency of an abbreviated, albeit objective posturographic test as an indicator of fatigue. Posturography was measured in 10 healthy adults (age 18-33 years, male/female 7/3). Baseline posturographic measurements were taken for each subject.

Apical hypertrophic cardiomyopathy and arrhythmia in military pilots.

Apical hypertrophic cardiomyopathy (ApHCM), a subtype of hypertrophic cardiomyopathy, may be found incidentally in healthy young adults. Arrhythmias are poor prognostic signs, and are the most frequent cause of sudden cardiac death. We present two cases of military aviators with ApHCM.

Head-up tilt test for recurrent syncope in pilots.

Syncope is defined as a sudden temporary loss of consciousness and postural tone that is associated with spontaneous recovery. Vasovagal or neurocardiogenic syncope is a common and usually benign cause of syncope. The mechanism may be cardioinhibitory, vasodepressor, or both.

Diabetes mellitus type 1 in five military aviators: flying with insulin.

Overview: Diagnosis of diabetes mellitus (DM) type 1 results in medical disqualification for all military aviation duties all over the world. The main concern is hypoglycemia, which can cause sudden incapacitation. Efforts to reduce the glucose levels and long-term complications increase the frequency of hypoglycemia.

Blood glucose awareness training helps return insulin-treated aviators to the cockpit.

Insulin-treated diabetes mellitus has traditionally been considered disqualifying for aviation duties, the major concern being the risk of hypoglycemia. This phenomenon may lead to impaired judgment and even loss of consciousness, potentially leading to a mishap. Blood glucose awareness training has been advanced as a strategy to avoid hypoglycemia by teaching individuals to use the appearance of autonomic and neuroglycopenic symptoms as indicators of decreasing blood glucose levels.

Sinus vein thrombosis following exposure to simulated high altitude.

A relation exists between high altitude exposure and a hypercoagulable state, the nature of which is not entirely clear. This has been mostly reported in mountain climbers. We report a 19-yr-old female, working as a high-altitude chamber instructor, who presented with severe frontal headaches which persisted for a month following routine high altitude chamber training.
