A novel treatment for constipation-predominant irritable bowel syndrome using Padma Lax, a Tibetan herbal formula.

BACKGROUND AND AIMS: Padma Lax, a complex Tibetan herbal formula for constipation was evaluated for safety and effectiveness in treating constipation-predominant irritable bowel syndrome in a 3-month double-blind randomised pilot study. METHODS: Patients were recruited from Hadassah Hospital's Gastroenterology clinic, using the Rome I Criteria for irritable bowel syndrome, and the international consensus criteria for constipation. Symptom severity was evaluated monthly by patients and gastroenterologist, using categorical and numerical rating scales. A patient diary recorded daily stool habit and trial medication. RESULTS: In 61 patients, (34 Padma Lax, 27 placebo), significant improvement was demonstrated after 3 months in the Padma Lax group compared to placebo in constipation, severity of abdominal pain, and its effect on daily activities, incomplete evacuation, abdominal distension and flatus/flatulence. A global assessment indicated that significantly more Padma Lax patients, compared to placebo, rated the current treatment superior to previous therapies tried for irritable bowel. Laboratory parameters displayed no clinically significant changes. Side effects, primarily loose stools in 7 Padma Lax patients responded well to lowering treatment dosage from 2 to 1 capsule/day. CONCLUSIONS: Padma Lax is a safe and effective treatment for constipation-predominant irritable bowel syndrome and may offer an alternative to the current multi drug approach.

Impact of new highways on road deaths: a case study in risk assessment.

Epidemiologists have generally avoided to assess risk for road deaths from high-speed highways. We examined the validity of the claim that the Trans-Israel Highway, a six-lane 320 km toll road with higher design speed, and raised speed limits (120 kph), will reduce road deaths. We used models showing that death tolls vary with the fourth power of rise in driving speed. Risk assessments was derived from estimates of increase in the highway-induced traffic, the impact of higher speed limits (from 110 to 120 kph) and the so-called spillover effect from speed habituation. We predict a large rise in the number of killed or injured, even if the death risks per vkm is low on the Highway itself. With the Trans-Israel Highway, death tolls--some 550 fatalities per year in 1995, could rise to as high as 900-1000 per year in 2010. Congestion produced by induced traffic will partially offset these effects. By contrast, death tolls from alternative strategies based on sustainable transportation policies could be reduced to less than 300 deaths per year. Risk assessment based on explicitly defined assumptions predicts high death tolls from the nationwide impact of raised speed on the Highway and its connecting roads. There is a need for new frameworks which impose the Code of Helsinki type requirements for the assessment and authorization of social decisions with adverse public health impacts.

Nutrition and quality of life in the aged: the Jerusalem 70-year olds longitudinal study.

Inadequate nutrition is a major problem of elderly people today. Yet, despite the prevalence and significance of the problem, there is little information on the nutritional status of elderly persons in the community, and its impact on their quality of life. During 1990-1991, as part of a first cross-section in a longitudinal medical and social study of 70-year olds in Jerusalem, we surveyed the nutritional status of this population. During the first phase, 605 people were examined in their homes; data were collected regarding socioeconomic status, education, self-perceived health state, use of medications and health services, and ADL. During the second stage, a sub-group of 463 people was examined in a geriatric outpatient clinic; all subjects underwent medical history, physical examination, cognitive assessment, psychiatric questionnaire, blood and urine tests, electrocardiogram, and pulmonary function tests. In addition, general hospital admissions and morbidity and mortality in the two years following the study were studied. The nutritional status of the participants was determined according to nutritional assessment (NA) scale, based on the Mini Nutritional Assessment (MNA). The majority of the study population lived at home, was without cognitive disturbance (86%), and was independent in ADL (83%). Based on NA > 24, 91% of the study population were in good nutritional state, 8.3% were at risk of undernutrition, and 0.7% were malnourished. There was a significant positive relationship between NA score and ADL as well as cognitive state. In addition, a strong negative relation was found between NA score and visits to the family physician in the previous fortnight, visits to the emergency room in the previous year, and hospital admissions in the following two years. An inverse relation, although not significant, was found between NA score and two-year post-study mortality. These results suggest that the nutritional status of the studied population is inadequate, and that the nutritional state is one of the major determinants of the quality of life in the elderly and therefore, should be part of any geriatric assessment. Elder population surveys are needed to identify and treat at risk elders.

The siesta in the elderly: risk factor for mortality?

BACKGROUND: During the siesta, blood pressure declines like it does during night sleep. Because cardiovascular and cerebrovascular events cluster during the morning hours, when hemodynamic changes from nocturnal baseline are maximal, we hypothesized that an additional sleep period during the day (the siesta) may increase cardiovascular and cerebrovascular events, and thus mortality. METHODS: A prospective population-based cohort study of 455 70-year-old residents of Jerusalem, Israel, using self-reported siesta at baseline and 6 1/2 years of total mortality data. RESULTS: The prevalence of the practice of the siesta was 60.7%. It was more prevalent among men than women (68% vs 51%, P<.001) and in survivors of previous myocardial infarction than in those without previous myocardial infarction (78% vs 58%, P = .009). After 6 1/2 years of follow-up (1990-1996), 75 subjects died. For those who practiced the siesta, total mortality was 20% vs 11% for those who did not (P = .01; risk odds ratio, 2.0; 95% confidence interval, 1.1-3.4). In a multiple logistic regression model that included several lifestyle descriptors, risk factors, and diseases, the siesta remained predictive of mortality (P = .03; risk odds ratio, 2.1; 95% confidence interval, 1.1-3.9).

Mortality in the Jerusalem 70-year-olds longitudinal study: does nifedipine have a role?

BACKGROUND: Short-acting nifedipine was found to be associated with increased mortality in elderly patients in some studies. METHODS: We examined effects of long-acting nifedipine in a longitudinal study of Jerusalem 70 year olds (448 participants). RESULTS: After follow-up of 6.5 years (1990-1996) 70 subjects died. We examined the effects of baseline variables on total mortality. Hypertensives had higher mortality than normotensives, 21.2% versus 13.8%, p = 0.01. Diuretic-treated patients (n = 72), mostly hypertensive (n = 71), had significantly higher mortality than non-diuretic-treated patients (n = 375), 45.5% versus 14.1%; p < 0.001. Although nifedipine-treated patients had a higher prevalence of coronary heart disease diagnosis than diuretic-treated patients (52% versus 35%), their relative risk of mortality was 0.8 (CI 0.4-1.4) of that of diuretic-treated patients. A multiple logistic regression model, including gender, systolic blood pressure, creatinine, cholesterol, diagnosis of congestive heart failure, cardiovascular arrest, diabetes, previous myocardial infarction, physical activity, nifedipine, other calcium channel and beta blockers and diuretics, found only serum creatinine and diuretic therapy associated with total mortality, p = 0.004 and p < 0.02, respectively. When interaction terms were added to account for drug combinations, diuretic therapy lost significance, but the combination of diuretics and beta blockers (probably representing a more severe form of hypertension) became significant, p = 0.03. CONCLUSION: Long acting nifedipine is not associated with increased mortality in elderly hypertensives.

Cost-benefit analysis of a national thalassaemia prevention programme in Israel.

OBJECTIVE: In Israel (population 5.7 million) there are around 200 known living subjects with thalassaemia major, of whom around 80% are from the northern district. This study aims at examining the costs and benefits of a national screening programme to prevent thalassaemia in Israel. MEASUREMENTS AND MAIN RESULTS: The lifetime healthcare costs of caring for a person born with thalassaemia major are $284,154. The costs of the home infusion service (33.1%) actually exceed the costs of the chelating agent itself (22.1%). The remaining 44.8% of costs are due to stay in hospital, operations, outpatient visits, laboratory tests, therapists, etc. Lost earnings and premature mortality costs account for a further $51,843 and $141,944 respectively for each case. A national screening programme would cost $900,197 and prevent around 13.4 homozygotes being born, at a cost of $67,369 for each birth prevented. The benefit-cost ratio of the programme to the health services is 4.22:1, which increases to 6.01:1 when a societal perspective is taken. However, around 13.0 homozygote births are still expected to occur, the majority owing to lack of compliance of patients at various stages in the screening process. The addition of a national health education programme for the higher risk non-Jewish population either nationally or in selected regions will incur extra costs, which may be covered by increased benefits as a result of better compliance with the screening programme. CONCLUSION: Israel should start to provide a nationwide thalassaemia screening programme as the monetary benefits to society (and even to the health services alone) will exceed the screening programmes costs.

Cost-benefit analysis of risperidone and clozapine in the treatment of schizophrenia in Israel.

In this study, the benefits and costs of treating schizophrenia with either risperidone or clozapine were examined. The lifetime drug-treatment cost incurred by a patient with schizophrenia in Israel was $US7561 (1996 values) with an initial 6-month trial with risperidone, compared with $US6326 with clozapine and $US3360 with typical antipsychotics. Total lifetime costs of psychiatric health services (excluding medications) by individuals who were continuously receiving typical antipsychotics were $US181,555 per patient. Assuming a 6.3% decrease in hospital use with typical antipsychotics and an absolute 30% decrease with risperidone or clozapine, the use of clozapine or risperidone reduced hospitalisation costs by $US7159 per patient, but increased community-care costs by $US1627 per patient, giving health-service benefit:cost ratios of 1.87:1 and 1.32:1, respectively. After adding indirect benefits resulting from increased work productivity (minus indirect costs related to increases in transport costs because of visits for blood monitoring during clozapine therapy), the benefit:cost ratios increased to 2.04:1 and 1.48:1, respectively. Assuming that clozapine caused a 30% decrease in hospital use by patients with new-onset schizophrenia, risperidone would have to decrease hospital use by 43.2% (i.e. a 13.2% relative advantage) for its societal benefits to justify its increased costs.

Prior hospitalization and age as predictors of mental health resource utilization in Israel.

A two-part demand model based on data from a psychiatric case registry was estimated in order to search for predictors of hospital-based psychiatric care utilization. Using only age as an independent variable, explanation of future resource utilization is considerably weaker than when number of cumulative days of psychiatric hospital-based service use during the previous five years is also included. Only a small marginal gain is achieved by also adding diagnoses. Prospective remuneration by capitating sick funds according to age and past hospital-based service utilization records is recommended to avoid the twin pitfalls of cream-skimming and a distorted allocation of resources for psychiatric services.

Flumazenil reversal of psychomotor impairment due to midazolam or diazepam for conscious sedation for upper endoscopy.

BACKGROUND: Flumazenil is a competitive benzodiazepine antagonist that acts to reverse their sedative and hypnotic effects. It is indicated in the management of benzodiazepine overdose, but its role in the routine reversal of endoscopic conscious sedation has not been defined. METHODS: Patients undergoing diagnostic upper endoscopy who received sedation with either diazepam or midazolam alone were given flumazenil 0.2 mg incrementally immediately following the procedure until awake. They were then asked to repeat three psychomotor tests measuring cognitive and motor skills, with their baseline scores compared with postprocedure scores over a 3-hour period. RESULTS: Full psychomotor function was restored to baseline values within 30 minutes after flumazenil in 79% of patients, with no differences in the reversal of psychomotor skill impairment observed between diazepam and midazolam sedation. There was no evidence of rebound sedation seen for up to 3 hours. No significant anterograde amnesia was evident in 78% of individuals. CONCLUSIONS: These results demonstrate that flumazenil's effects on reversing psychomotor impairment are similar when midazolam or diazepam are used for conscious sedation. However, the potential usefulness of routine flumazenil reversal of conscious sedation will require further evaluation of specific psychomotor performance skills (such as driving a car) before we lift the admonition against leaving the endoscopic suite unattended, driving a vehicle, or operating complicated machinery for several hours.

Decreased hospital utilization by older adults attributable to a home hospitalization program.

OBJECTIVE: To evaluate the cost effectiveness of a short-term home health care program for older people, Home Hospitalization (HH), compared with the alternative of regular ambulatory care with general or geriatric hospitalization as necessary. SETTING: Our HH was initiated in November 1991 to serve Jerusalem residents. Program staff included physicians, nurses, and paramedical professionals. Other medical/hospital services were provided nonselectively by the general medical personnel of the various hospitals in Jerusalem. STUDY DESIGN: Patients over the age of 65 were either referred to the HH program (study group, n = 36,500) or to routine medical care (control group; n = 9000) depending on their Sick Fund assignment. Hospital utilization rates per enrollee were studied prospectively and compared both between the two groups and with hospitalization rates in the year before the initiation of the program. RESULTS: During the first 26 months of operations, the HH program cared for 741 older persons for a total of 37,290 days' care at an average daily costs of $30.06 (1992) and $23.64 (1993). Annual general hospitalization rates per person declined in the study group from 2.80 days in the 1991 baseline period to 2.65 days in 1992 and to 2.54 days in 1993. Hospitalization rates in the control group increased from 2.62 in 1991 to 2.70 days/member and 2.71 days/member in 1992 and 1993, respectively. Annual geriatric hospitalization rates declined considerably in the study group from the 1991 baseline of 1.49 to 1.34 (1992) to 1.33 (1993). The control group experienced a small decrease from 1.64 (1991) to 1.58 (1992) and then a rise to 1.68 days per member in 1993. For the 26-month duration of the program, estimated savings of 20,773 general hospital days ($5.54 million) and 8486 geriatric hospital days ($0.98 million) exceeded its costs ($0.97 million), providing a cost/benefit ratio of 5.7/1. In addition, patient satisfaction was high. CONCLUSION: The HH program provided a cost effective substitute for care in a geriatric or general hospital for Jerusalem's elderly.

A community based study of failure to thrive in Israel.

OBJECTIVE: To examine the characteristics of infants suffering from failure to thrive in a community based cohort in Israel and to ascertain the effect of failure to thrive on their cognitive development. METHODS: By review of records maintained at maternal and child health clinics in Jerusalem and the two of Beit Shemesh, epidemiological data were obtained at age 15 months on a cohort of all babies born in 1991. For each case of failure to thrive, a matched control was selected from the same maternal and child health clinic. At age 20 months, cognitive development was measured, and at 25 months a home visit was carried out to assess maternal psychiatric status by questionnaire, and the HOME assessment was performed to assess the home environment. RESULTS: 3.9% of infants were found to have fallen below the third centile in weight for at least three months during the first year of life. Infants with failure to thrive did not differ from the general population in terms of obstetric or neonatal complications, birth order, or parents' ethnic origin, age, or years of education. The infants with failure to thrive did have lower birthweights and marginally smaller head circumferences at birth. Developmental assessment at 20 months of age showed a DQ of 99.7 v 107.2 in the matched controls, with 11.5% having a DQ below 80, as opposed to only 4.6% of the controls. No differences were found in maternal psychiatric problems as measured by a self report questionnaire. There were, however, significant differences in subscales of the HOME scale. CONCLUSIONS: (1) Infants who suffered from failure to thrive had some physiological predispositions that put them at risk; (2) failure to thrive may be an early marker of families providing suboptimal developmental stimulation.

Laboratory reference values for the 70 year olds.

Reference values for common laboratory tests were determined as part of a cross-sectional survey of 70 year olds in Jerusalem in 1991. Subjects were systematically chosen from electoral lists. They were extensively interviewed regarding demographic, socioeconomic and health characteristics. Subsequently, 456 underwent a thorough medical examination including hematologic, biochemical and endocrinologic testing. Analysis of disease-specific mortality and hospital morbidity at 3 year follow-up proved these subjects to be representative of the overall Jerusalem Jewish population of 70 year olds. Test-specific reference subgroups were determined to exclude effects of known diseases and drug consumption. Reference values in these subgroups differ significantly from reference values currently used for adults without regard to age. The determination of disease for subjects provided the opportunity to identify changes that might reflect normal aging and those that might be affected by subclinical pathology. Interpretation of laboratory testing of older adults must consider the age-related differences in reference values.

The nutritional status of 70 year olds in Jerusalem.

Inadequate nutrition is a major problem of elderly people today, a rapidly growing segment of western societies. Yet information on the nutritional state of the elderly in the community is much needed. We surveyed the nutritional status of a cohort of 70 year olds living in western Jerusalem. A total of 605 persons were interviewed in their home regarding socioeconomic variables, education, self-assessed global health status, use of medicines, and activities of daily living (ADL). In the second stage, a subsample of 463 of the above attended an outpatient geriatric clinic where a medical history was taken and a physical examination, a cognitive test, a psychological profile, blood and urine tests, electrocardiogram, pulmonary function tests, and grip strength measurement performed. Most of the sample population lived at home. Twelve percent reported having severe financial problems. Approximately 14% exhibited some cognitive problems, 83% were totally independent in ADL, and only 15% were housebound with 2.5% being bedbound. Body mass index (BMI) of < 19 kg/m2 was found in 1.1% of the population, while obesity, defined as a BMI > 30 kg/m2, was found in 13.5% of males and 28.6% of females. Polypharmacy was prevalent. A quarter of the study population were taking three or more prescription drugs. Serum triglycerides were below the normal limit in 7.3% of males and 4.7% of females, while total serum cholesterol concentrations were low in 13.9% and 4.7% of males and females respectively. Serum albumin was found below the lower limit of normal (35 g/l) in 16.9% of females and 11.4% of males. The significance of these results, their relation to other nutritional surveys, and their implications for the future are discussed.

Characteristics of falls in 70 year olds in Jerusalem.

Falling is a serious and common problem among the elderly and may result in injury and functional deterioration. The characteristics and risk factors for falling were studied in a cross-sectional study of a cohort of 70-year-old community-dwelling Jewish elderly in Jerusalem. The cohort was found to be representative of the total 70-year-old population of Jerusalem by virtue of having similar hospitalization and mortality rates. Around 28.2% of the cohort reported falling during the past year. Women were more likely than men to have fallen during the past year (39 vs. 19%; P < 0.001). Falls occurred mainly outside of the home, resulting in fractures in 8.4% of persons who fell, all of them women. A female gender, low visual efficiency, poor self-reported general health status, low serum hemoglobin levels, and low lymphocyte counts were associated with a higher incidence of falls. There was no relationship between the pattern of pharmaceutic drug use or utilization of health care services and the risk of falling. We conclude that among the younger elderly, characteristics of falls and risk factors may be different from those in the older elderly.

The Jerusalem 70 year olds longitudinal study: gastrointestinal findings.

The objective of this part of the first cross-section of the longitudinal study of a cohort of 70 year olds in Jerusalem was to survey the gastrointestinal symptoms and signs of this heterogeneous population and thus contribute to the knowledge of the development of gastrointestinal diseases in this age group. A total of 605 persons replied to a home-visit questionnaire gathering data on socioeconomic and migration variables. Later on, 463 of these attended an examination at the Geriatric Research Institute where an in-depth anamnesis and physical examination were conducted. A battery of biochemical and hematologic blood tests were performed as well as urine analysis, ECG, and pulmonary function tests. At 3 year follow-up, the interviewed subjects, subjects examined in the hospital, and the control group consisting of 70 year olds who were not examined, were compared. By the measures of disease-specific mortality and hospital morbidity, the three groups were found to be similar, demonstrating that the sample population does represent the total Jerusalem 70-year-old population. This paper describes the symptoms, signs and laboratory results of the gastrointestinal part of this study. Up to a third of the subjects complained of upper gastrointestinal symptoms, most prominent of which was heartburn. Almost 10% of subjects complained of abdominal pain occurring at least once a week, but less than 1% noted left lower quadrant pain. There was a direct association between upper abdominal pain and symptoms of ischemic heart disease. The second part of this study, which began in 1996, will provide additional information regarding the natural history of these complaints.

Determinants of loneliness in Jerusalem's 70-year-old population.

This study aims to find the determinants of feelings of loneliness in 70 year olds living in Jerusalem. Results based on home interviews (n = 605) of a 40% systematic sample of 70 year olds in the electoral register showed that around 46.3% of females and 21.3% of males reported being lonely. Persons of European/North American origin felt less lonely than those of Asian or African origin, probably due to the former's wider social support network, perceiving friends, neighbors or other relatives as being available to back up children in an emergency. The major factors associated with loneliness were: being depressed, having a poor self-assessed health status, not attending synagogue, and being widowed but not remarried. Factors that did not reduce loneliness included having paid employment, watching TV or listening to the radio. No association was found between cognitive status and loneliness. Our systems model suggests a strong reciprocal relationship between loneliness and depression.
