Background: Depression has been shown to be associated with cervical tumors (CTs), an association mostly demonstrated in studies in which temporality could not have been ascertained.

Objectives: To study the association between depression and CTs and the influence of co-morbidities of this association in a large cohort study.

Methods: A retrospective computer-based cohort study was conducted. The cohort included 357,450 female members of Maccabi Healthcare Services. The cohort was classified as depressed or non-depressed using the International Classification of Diseases 9/10 codes. For each subgroup, demographic characteristics, behavioral characteristics, co-morbidities, and CTs diagnosis were obtained. The burden of co-morbidities was defined as the sum of major co-morbidities. We used zero-inflated negative binomial regression analysis due to over-dispersion to estimate the relative risk (RR) for CTs with 95% confidence interval (95%CI).

Results: Depression was diagnosed in 15,789 women. Among this group, CTs were diagnosed in 1585 (10.0%). Among the 341,661 non-depressed, CTs were diagnosed in 4185 (1.2%). After adjustment to age and socioeconomic status, the association between depression and CTs was RR=9.2 (95%CI 8.7–9.9, P-value < 0.0001). The association between depression and CTs increased as the burden of clinical conditions increased (P-value < 0.0001).

Conclusions: Women with depression are at a higher risk for CTs, especially among those who have several co-morbidities. Tighter gynecology surveillance is crucial among these women.

Background: Trans-aortic pressure gradient in patients with aortic stenosis and left ventricular systolic dysfunction is typically low but occasionally high.

Objectives: To examine the distribution of trans-aortic PG[1] in patients with severe AS[2] and severe LV[3] dysfunction and compare the clinical and echocardiographic characteristics and outcome of patients with high versus low PG.

Methods: Using the echocardiographic laboratory database at our institution, 72 patients with severe AS (aortic valve area ≤ 1.0 cm2) and severe LV dysfunction (LV ejection fraction ≤ 30%) were identified. The characteristics and outcome of these patients were compared.

Results: PG was high (mean PG ≥ 35 mmHg) in 32 patients (44.4%) and low (< 35 mmHg) in 40 (55.6%). Aortic valve area was slightly smaller in patients with high PG (0.63 ± 0.15 vs. 0.75 ± 0.16 cm2 in patients with low PG, P = 0.003), and LV ejection fraction was slightly higher in patients with high PG (26 ± 5 vs. 22 ± 5% in patients with low PG, P = 0.005). During a median follow-up period of 9 months 14 patients (19%) underwent aortic valve replacement and 46 patients (64%) died. Aortic valve replacement was associated with lower mortality (age and gender-adjusted hazard ratio 0.19, 95% confidence interval 0.05–0.82), whereas trans-aortic PG was not (P = 0.41).

Conclusions: A large proportion of patients with severe AS have relatively high trans-aortic PG despite severe LV dysfunction, a finding partially related to more severe AS and better LV function. Trans-aortic PG is not related to outcome in these patients.

Background: Prone sleeping has been recognized as a risk factor for sudden infant death syndrome. Ten years ago, non-prone sleeping was recommended in many countries around the world including Israel. The rate of infants sleeping prone and the rate of parents' adherence with the recommendations have not been studied.

Objectives: To study infants' sleep position and parents’ adherence to recommendations, and to identify risk factors for prone sleeping following the campaign to prevent prone sleeping in the Israeli population.

Methods: We conducted a longitudinal telephone survey with the parents of 608 randomly selected 2 month old infants, repeated at 4 and 6 months.

Results: Non-prone sleeping decreased from 75% to 67% and 63% at 2, 4 and 6 months respectively. There was a significant relationship between prone positioning and the use of a home apnea monitor at 2 months (P = 0.038, odds ratio 1.37, 95% confidence interval 0.94–2.15). Other risk factors for prone sleeping were the level of religious practice, with ultra-Orthodox Jews having the highest prevalence (2 months: OR[1] 2.78, 95% CI[2] 1.75–4.55) and higher parity – especially in families with more than five children (P = 0.041).

Conclusions: The prone sleeping position is relatively high in Israel. Groups at high risk were closely associated with the level of religiousness and parity. Efforts to promote supine sleeping should be directed towards identifiable groups.

Background: Unexplained pulmonary hypertension is assumed to occur mainly in young adults.

Objectives: To describe the features of the disease in older patients and compare them to those in PHT[1] patients of all ages.

Methods: We conducted a retrospective evaluation of the files of patients over 65 years of age in whom UPHT[2] was diagnosed between 1987 and 1999 at two PHT centers serving a population of 4 million. Patients were followed for survival until March 2003. Clinical variables of the study patients were compared to those in PHT patients of all ages.

Results: The study group included 14 patients, 10 females and four males, with a mean age of 70.5 ± 6.7 years. The calculated mean annual incidence of UPHT for the study population was one new case per year per million persons. Seven patients (50%) had systemic hypertension. The mean interval from onset of symptoms to diagnosis was 8.3 months. At diagnosis, 64% of patients had functional capacity of III-IV according to the New York Heart Association classification, and 43% had right heart failure. Mean systolic pulmonary artery pressure was 80 ± 21 mmHg, peripheral vascular resistance 11.7 ± 7 mmHg/L/min, cardiac index 2.16 ± 0.81, and mean right atrial pressure 10.5 ± 5.9 mmHg. Median survival time was 43 months; survival rates for 1 year, 3 years and 5 years were 92.6%, 50%, 40%, respectively. Compared to data from the U.S. National Institute of Health Registry, UPHT in older patients is more common in females, but the incidence as well as clinical, hemodynamic and survival parameters are similar to those in PHT patients at any age.

Conclusions: UPHT occurs in the elderly more frequently than previously thought, with similar features in PHT patients of all ages. The coexistence of systemic and pulmonary hypertension warrants further investigation.

Background: With the introduction of surgery and percutaneous balloon valvuloplasty for relieving severe mitral stenosis the natural history of the disease has markedly altered.

Objectives: To determine the natural history of patients with moderate mitral valve stenosis.

Methods: Demographic, clinical and echocardiographic data were evaluated in 36 patients with moderate mitral stenosis during a follow-up of 71 ± 15 months.

Results: The 36 patients comprised 32 women and 4 men with a mean age of 43.7 ± 12.2 years; 28 were Jewish and 8 were of Arab origin. During follow-up, there was a significant decrease in mitral valve area, with an increase in mean mitral valve gradient and score. Mean loss of mitral valve area was 0.04 ± 0.11 cm2/year. No correlation was found between disease progression and age, past mitral valve commissurotomy, baseline mean gradient or mitral valve score. Larger baseline mitral valve area (P = 0.007) and Arab origin (P = 0.03) had an independent correlation to loss of mitral valve area. Fifteen patients (42%) did demonstrate any loss in mitral valve area during the follow-up period.

Conclusions: The rate of mitral valve narrowing in patients with moderate mitral stenosis is variable and cannot be predicted by patient’s age, past commissurotomy, valve score or gradient. Secondly, larger baseline mitral valve area and Arab origin showed an independent correlation to loss of mitral valve area; and finally, in many patients valve area did not change over a long observation period.

Background: Percutaneous transluminal septal ablation was recently introduced as an alternative to surgical treatment of hypertrophic obstructive cardiomyopathy. In this procedure, alcohol is injected into a proximal septal artery to create a localized myocardial infarction.

Objectives: To characterize the immediate and mediumterm results following PTSMA.

Methods: Of 13 patients referred for PTSMA, 8 were found suitable for the procedure. Hemodynamic parameters were evaluated prior to and following the procedure, and clinical and echo-Doppler parameters at 2 weeks and 9 months later.

Results: The procedure was technically successful in all patients. Resting left ventricular outflow gradient at rest (by Doppler) fell from 82 + 37 to 15 + 8 mmHg (P<0.001) 9 months later. Late post-procedural gradient after the Valsalva maneuver was 2 + 24 mmHg. The degree of mitral regurgitation fell from 2.0 + 0 to 1.5 + 0.5 (P<0.05). New York Heart Association class for dyspnea improved from 2.8 + 0.5 to 1.8 + (P<0.01) and Canadian Cardiovascular Society class for angina from 2.0 + 1.3 to 1.3 + 1.2 (P=0.08). Complete right bundle branch block developed in six patients, temporary complete atrioventricular block in three, and persistent block requiring permanent pacing in one. No flow in the distal left anterior descending coronary artery (presumably due to spilling of alcohol) was seen in one (with development of a small antero-apical infraction) and ventricular fibrillation 2 hours post-procedure in one. None of the patients died.

Conclusion: PTSMA provided a substantial reduction in left ventricular outflow gradient associated with an improvement in symptomatology. Serious complications are not uncommon. Long-term follow-up is unknown.

Background: Data regarding the epidemiology of secondary pulmonary hypertension are scanty.

Objectives: To describe the spectrum and relative incidence of background diseases in patients with significant secondary PHT.

Methods: We identified 671 patients with systolic pulmonary artery pressure of 45 mm Hg or more from the database of the echocardiographic laboratory. Their background diseases were recorded and classified into three subgroups: cardiac, pulmonary and pulmonary vascular disease without pulmonary parenchymal disease. Age at the first echocardiographic study, gender and systolic PAP values were recorded. Data between the three subgroups were compared.

Results: The mean age of the patients was 6515 years, mean systolic PAP 6114 mm Hg and female:male ratio 1.21:1. At the time of diagnosis 85% of the patients were older than 50. PHT was secondary to cardiac disease in 579 patients (86.3%), to PVD without PPD in 54 patients (8%) and to PPD in only 38 patients (5.7%). Mean age and mean systolic PAP did not differ significantly among the three subgroups. There was a significantly higher female: male ratio in patients with PVD without PPD compared with cardiac or pulmonary diseases (1.7:1 vs. 1.2:1 and 1.7 vs. 0.8:1 respectively, P0.05).

Conclusions: The majority of patients with significant PHT are elderly with heart disease. PVD without PPD and chronic PPD are a relatively uncommon cause of significant PHT. Since the diagnosis of PHT is of clinical significance and sometimes merits different therapeutic interventions, we recommend screening by Doppler echocardiography for patients with high risk background diseases.
