Geographic and extraterrestrial aspects of morbidity and/or mortality patterns from myocardial infarction and stroke.

Two authors (M.K. and M.M.) provided insight into a manuscript submitted by them elsewhere for publication and kindly offered for meta-analysis data on the monthly incidence from January 1989 up to December 2004, of 6094 cerebral infarctions, 414 intracerebral and 277 subarachnoid hemorrhages, cases admitted at the Neurological Clinic in Nové Zamky, Slovakia. Spectral components with a period exceeding (beyond = trans) the length of the calendar year--transyears--reported originally by M.K. and M.M. are here also documented linearly on original data without and after detrending by the fit of first- or second-order polynomials. For intracerebral and subarachnoidal hemorrhage, the zero-amplitude (no-rhythm) assumption is rejected (P < 0.05, not corrected for multiple testing) for the transyear but not for a precise 1.0-year trial period. As reported earlier by M.K. and M.M., the transyear's amplitude is larger than the calendar year's amplitude for all three series of stroke incidence in Slovakia. The putative importance of the new findings stems from earlier and new analyses revealing other spectral components that are presumed signatures of magnetoperiodisms, e.g. about 50- and 7-year components in about five decades of diagnostically unqualified, pooled data on stroke in Minnesota. There is, however, the danger of relatively small numbers providing artifacts for loosely defined transyears. The original cosinor approach by M.K. and M.M., testing anticipated periods, had its strength. The observation of a quindecadal component in mortality from strokes in Minnesota supports the presence of signatures of effects from extraterrestrial space in acute human pathology such as strokes, myocardial infarctions and sudden cardiac death. Magnetoperiodic mechanisms remain to be investigated further as added strokes accumulate in Nové Zamky and greater Slovakia as well as for sudden cardiac death where transyears have been documented in the Czech Republic, in Arkansas and particularly in Minnesota, but not elsewhere (as yet?). This study is also a plea for worldwide access to morbidity, mortality and natality data that constitute a largely unexploited treasure, brought to the fore mainly for relatively short-term comparisons of the effect of interventions against the fiction of imaginary baselines.

Rewards in practice from chrono-meta-analyses 'recycling' heart rate, ectopy, ischemia and blood pressure information.

Previously published average curves of heart rate and duration of ischemia in patients with coronary artery disease, studied while on placebo or on treatment with either atenolol or diltiazem, are re-analysed for the assessment of about-daily (circadian) and about-weekly (circaseptan) changes in these variables and of any treatment effect on rhythm characteristics. In addition to circadians, a circaseptan pattern characterizes the duration of ischemia in all three aforementioned study stages. Both drugs decrease the duration of ischemia, atenolol, but not diltiazem, also affects the circadian amplitude and acrophase of this variable. A circaseptan pattern is also found for heart rate on placebo and on treatment with atenolol, but not with diltiazem. Both drugs lower heart rate and the circadian amplitude and 24-h standard deviation of heart rate, atenolol much more markedly than diltiazem. Circadian and circaseptan rhythm characteristics and their alterations with treatment serve to optimize treatment by timing its administration. Chronobiologic surveillance of variables that are being readily monitored as-one-goes by modern implantable devices can also serve for the validation of the effectiveness of drug and electrical therapy. Rhythm alterations, in turn, can provide the earliest warnings of an elevated disease risk and lead to an improved diagnosis.

[Promoting physical activity in overweight and obese patients: counseling in primary care from Italy (Cesena, 2002--2003)].

Lack of physical activity and obesity represent important public health problems. The objectives of the current study is to evaluate the effects of a counseling intervention (the PACE protocol) conducted by general practitioners and designed to motivate persons who are overweight or obese to increase their levels of physical activity. The counseling was offered 145 patients with a BMI > or =27 who were seen between May 2002 and April 2003 in the offices of 10 general practioners. The intervention, which lasted 3-5 minutes, was conducted during routine visits, based on the Prochaska-DiClemente model of behavioral change. Changes in the motivation of the patients to engage in physical activity and actual changes in levels of activity were measured, as were BMI and abdominal circumference. The median followup was 9 months. Among the 145 eligible patients, 103 (71%) agreed to particpate. Six months following the counselling, there was a significant change in both the motivational status and physical activity of the group, and they experienced significant decreases in BMI and abdominal circumference. Counseling using the PACE model appears to positively influence levels motivation and of physical activity in those patients who agreed to participate. Further studies should be conducted to evaluate the effectiveness of this strategy in other settings and the public health benefits of such counseling.

Chronobiologic perspective of international health care reform for the future of children.

The realization of the implications of splitting the atom ended a tragic war. The nuclear age ensued. Likewise, a devastating escalation of health care costs could be ended by realizing the implications of splitting the normal range. Our currently disease-cure-oriented health care system does too little too late. Chronobiology could change this status quo into a system that recognizes risk early; it would gain new information from the resolution of predictable variations that take place within the physiologic range. Investment into vaccinations leads to returns in the form of savings in suffering and cost. A relatively modest investment into a 'Blood Pressure Health Start', pursued while chronobiology is being taught as an integral part in primary, secondary, higher and continued education, may not only drastically and in some respects promptly reduce the health care bill, but it would help the economy of the country that invests into the development of instrumentation for a chronobiologic systems approach. On the one hand, reducing the number of cases of catastrophic diseases, via improved diagnosis (to start with) of the blood pressure status, is likely to substantially reduce the budget deficit by reducing the legitimate and essential costs of care (to start with, of strokes and heart attacks, that kill more people than all other diseases combined and that have blood pressure disorders as their major risk factor). On the other hand, by implementing a novel health care system which also involves new technology that can become in demand worldwide, any trade balance will be improved.(ABSTRACT TRUNCATED AT 250 WORDS)
