The discovery in biology of far-transyears, 15–20 months in length 123, is in keeping with oscillations of the same longer-than calendar-yearly period in the speed and proton density of the solar wind 45. Hence, this wish for healthy, lucky and blessed transyears rather than years. Let us speculate that we are genetically programmed for a certain number of transyears (or years) and that an attempt to synchronize transyears rather than years, also pure speculation, could automatically prolong the remaining lifespan by one or two-thirds in the case of far-transyears or by some weeks in the case of a near-transyear. What is not speculation is that transyears are a transdisciplinary fact of life and that they can beat with a spectral component with a period of the length of the calendar year 123, and, what seems critical for this journal, each about-yearly component can influence the circadian system.

Figure 1 presents a tentative scheme for classification of trans-yearly spectral components. The suggestions are tentative; they imply that the cis- and trans-annuals, as defined here, have an amplitude (A) different from zero, established by the non-overlap of zero by the 95% confidence interval (CI) of A, and that the component is anticipated, i.e., confirmed by analyses of an independent separate prior series. In addition to these considerations of statistical significance and prior documentation, there is a most important added consideration of reciprocal mutually supporting cyclicities found in and around us. These are much more numerous in the case of the spectral region around the year than in that of the day. Moreover, about-yearly cycles, notably the non-photic magnetoperiodisms, usually are mere influencers of the biological year, rather than necessarily long-term synchronizers, being often transients themselves, by contrast to cycles with a period corresponding in length to the day. In the case of the year, the far-transyears centering around 1.3 years and around 1.6 years are all different and transient, and, this is new, their influence is also dependent upon local factors. The far-transyears were discovered by physicists in the solar wind with prior hints from geomagnetics and auroral counts 45 while the near-transyears in the solar wind, in the antipodal geomagnetic index as well as in biology, were found and validated by us. Because of the wobbliness of the period and the circumstance that the external cycles may not lock-in the biological ones, variability is much greater in the about-yearly spectral region than in the circadian domain. In the case of the about-yearly vs. that of the about-daily variation, about-yearly asynchronization must be considered rather than desynchronization, as in the case of circadians.

For discussion by transdisciplinary nomenclature committees, terms in English are emphasized. With advice by Prof. Robert Sonkowsky, proposed Latin equivalents are added for vanishing classicists. Essentially, "ad-transannual" means "a little longer than a year"; "ad-cisannual" means "a little shorter than a year"; "transior-annual" means "much longer than a year"; and "citerior-annual" means "much shorter than a year". Some specific limits that seem reasonable in the light of available physical and biological evidence are given in the scheme. The single syllable 'ad' is preferred to the 2-syllable 'prope', 'juxta', 'propter', 'minus' (paired with 'plus') or the 3- or 4-syllable 'proprior', 'proximus', 'vicinus', or propinquus'. While to a purist among grammarians the coinages adtransannual and adcisannual may seem preposterous (a word constituting itself an illustration of cumulative prefixes) precisely because of the piling on of prefixes, there are also other precedents in Late Latin such as exinventio ("discovery") and perappositus ("very suitable/apposite"). Normal assimilation of 'd' to 't' and 'c', respectively, may then result in the spellings and pronunciations "attransannual" [at-trans-annual] and "accisannual" [ak-sis-annual] acceptable as English pronunciation, notably by speakers with native romance languages, who may face difficulty with the near and far as added prefixes.

Difficulties may stem from the fact that analyses usually provide estimates in frequency (not period) terms, and from the criterion of 95% CIs that may not be available. We need to allow for situations when, because of too-wide (or unavailable) CIs, we can diagnose only a candidate trans- or cis-annual component, when 95% CIs of τ overlap the limit distant from the year. By the same token, we may not be able to specify near or far, e.g., because of the brevity of the series. In other words, we cannot say whether we have a near- or a far- trans- or near- or far- cis-year, when there is an overlap by 95% CIs with the corresponding finer limits, shown on the scheme (Figure 1).

For the case of "circannual", we again go by 95% CIs rather than by the point estimate. In the circannual case, the 95% CI overlaps the 1-year estimate under usual conditions, bearing in mind that under unusual, e.g., constant conditions, circannuals are also amenable to free-running, in which case the 95% CI may no longer cover 1 year but will have to be tested further for non-overlap with the pertinent environmental cycle in the case of a biologic cycle and vice versa for non-overlap of a natural environmental cycle with an anthropogenic cycle. In the trans- or cis-annual case, the 95% CI does not cover the 1-year period under usual conditions, i.e., cis- or trans-annuals can be asynchronized rather than desynchronized. Strictly speaking, circannual cannot be an overall term, but almost certainly, whatever committees may decide, it will be (mis-)used as such. "Far-" and "near-", "cis-" and "trans-" and "citerior-" and "transior-" annual are hyphenated here only to indicate their derivation and need not be written with hyphens. We propose using circannual, transannual or cisannual and their refinements, only operationally as a function of periods and their 95% CIs. Matters of synchronization, desynchronization or asynchronization may then possibly emerge from the context of a given situation and from further testing.

Trans- and cis-years lead to a novel chrono-helio-geobiology, awaiting application of the tools of transdisciplinary chronomics. It has been a challenge to look at circadians for the past half-century, but knowledge concerning them will not be completely useful before we answer another set of questions based on the evidence in Table 1.

Table 1 demonstrates in the incidence of myocardial infarction (MI) in the Czech Republic and, for sudden cardiac death (SCD), in the strict sense, excluding MI, both a calendar year and a candidate transyear component in Arkansas as well as in the Czech Republic yet only a transyear, no calendar year for SCD in Minnesota. Signatures and thus perhaps a putative influence of magnetic cycles on human SCD constitute a new feature of SCD pathology, which gains in prominence when death from MI and from other unknown or unspecified causes is ruled out, as it is likely to be when ICD10 code I46.1 is used, as is the case in Table 1.

Of interest are great geographic/geomagnetic differences insofar as no transyears, only calendar-yearly components, were detected in 3 locations, while in 3 other locations, transyears were present, in two of these, with a coexisting calendar-yearly component, with nearly equal prominence, while in Minnesota, only a transyear was thus far detected. A clarification of the roles played by local as well as global influences could also be based on transyear vs. calendar-yearly amplitude ratios when both components are present, which, however, is not the case in 4 of 6 locations. There is the challenge of developing eventual countermeasures.

But first, we seek a clue as to why, for SCD in Minnesota, the prominence of the transyear exceeds by far any seasonal, thus far undetected influence of the harsh environmental temperature change in its mid-continental climate in the summary of 5 consecutive years, and why, in Arkansas and the Czech Republic, the transyear's prominence is about the same as that of the seasons, and why it seems to be absent in 3 other locations and furthermore why in MI the prominence (gauged by the amplitude) of the calendar year is so far greater than that of the transyear (by contrast to the case of SCD). Systematically collected data from different areas of the world will open a new chapter in transdisciplinary science, with particular pertinence at the extremes of extrauterine life, in natality as well as in mortality.

Optimization of the about-yearly spectral region may also be considered, along with Hufeland's consideration of the daily routine in studies aimed at prolonging high-quality life 6. Notably in the baby, but also in the elderly, the far-transyear's amplitude can exceed that of a spectral component with the length of a calendar year, and hence transyears are especially important to pediatricians and geriatricians alike and, perhaps, for scholars in the field of circadian rhythms.

Beyond 85 years of age, Theodor Hellbrügge, chronopediatrician par excellence and professor emeritus of social pediatrics at the University of Munich, continues actively as a mentor of the specialty he founded 789. Our earlier laudatios 71011121314 include a symposium dedicated to Theo 14, which competes with his 2 honorary professorships, 17 honorary doctorates, and many more institutes built for handicapped children after his model center in Munich. Theo started as a solid contributor of chronobiological data, he continued in the field via a school of medical students who wrote their doctoral theses and participated broadly in this field, most of them in Minnesota 1516171819202122232425262728293031323334353637383940414243444546474849505152535455565758, many of them concerned with prehabilitation in terms of vascular disease prevention 24252627282930313233343839404142434445464749525355. Methodological papers were critical 1516171819 to a time-microscopic inferential statistical assessment of both drug-induced phase shifts and circadian phase-response maps, given in each case with the uncertainties involved (Figures 2, 3, and 4) 15.

Theo himself turned in the interim to the care of children with obvious disabilities. He continues with concerns about them to detect early alterations for timely remedies, a preventive task par excellence, which could benefit from chronomics, the resolution of time-structural (chronome) alterations in the physiological range. Accordingly, chronobiologists honored Theo at a meeting on "Time structures – chronomes – in child development", leading to a proceedings volume of 256 pages 14. On the basic side, this conference documented that the human newborn may recapitulate the development of life on earth by a chronome different from that of an adult. The amplitude of about 7-day vs. about-24-hour variation in the human circulation has been shown in gliding spectra in this journal earlier 59. The amplitudes of spectral components' longer-than-yearly periods can be more prominent than about-yearly changes 14. About 21-yearly cyclicities (Figure 5) pose interesting problems of geographical differences 14. These about 21-year cycles correspond in period length to the sunspots' bipolarity cycle 60, but are nearly in antiphase in Minnesota vs. Denmark (Figure 6), raising the question of how different aspects of the earth's surface may bring about antiphasic responses to putative non-photic solar effects, with contributions that are hardly negligible (Figure 7). Possible geomagnetic or other environmental effects on the period and thus indirectly on the phase are implied in Table 1 with respect to sudden cardiac death in a strict sense, excluding death from MI 62. In conjunction with chaos and trends – in chronomes – these complex cycles provide insight into many developmental biological processes and behavioral patterns in infancy and childhood 14 and also at the other end of life 62 (Table 1).

In his own recent words 63, Theo also "had an interest in the work in Prague of pediatricians and psychologists like Matajcek, Dolanski and Donovski, who were interested in systematically analyzing a neonatal deprivation syndrome. From their lessons, [Theo] formulated the concept of developmental rehabilitation in Munich, with new programs for early diagnosis, early therapy and early incorporation into society." In seeking a niche for his endeavor, he called his program "rehabilitation" rather than "prehabilitation" 6465. Thus, for his endeavors, he was able to tap into a source of funds already officially earmarked for rehabilitation.

To continue in his words 63, in practice, Theo "used the plasticity of the central nervous system in early childhood to develop a targeted treatment of children who have innate or early-acquired disturbances or actual damage in order to save them from the fate of a lifelong handicap. In so doing, he is proud that he helped completely deaf children, via their mothers, to learn normal speech when they were offered speech treatment in the first weeks and months of life. This concept was extended worldwide and led to the publication of books for parents on 'The First 365 Days of a Child's Life' 8." Theo believes that "this is the most important discovery of the newest pediatric research, in which Czech and Slovak researchers like Janos Papousek participated and discovered that the newborn is already a very competent 'learning system'." Indeed, the evaluation of hearing loss in infants and young children requires early identification and assessment of hearing impairment, an endeavor of critical importance to cite John Jacobson and Kara Jacobson 66: "New technology and techniques have helped make the process more efficient and accurate for pediatricians."

By 1960 at Cold Spring Harbor 67 and again thereafter at the New York Academy of Science 68, Theo had reported that the human child exhibits its ubiquitous and important about 24-hour rhythms with a delay after birth. His data have gained from chronomics from the analysis of time structures, a development comparable to the mapping of genes – genomics – both chronomics and genomics spawned by genetics 14. Chronomics is a time-structurally qualified physiological genomics, based on time series analyzed for rhythms (as well as, whenever the data density will permit, for chaos, and, whenever time series length will permit, for trends). To Theo's lasting credit, he systematically distanced himself from single sample spotchecks.

Theo Hellbrügge's contributions illustrate a solidly founded now widely distributed conceptual structure resting on a productive life's work available again in his own words 9. A few graphs and a few numbers (e.g., for rhythms with their periods and other characteristics) can meaningfully in time summarize thousands or millions of data 1014.

With one of his colleagues 7, we can summarize how Hellbrügge's original evidence has borne many fruits in preventive health care:

• some in ethology as a method to account for the development of children,

• mother-infant-interactions as a decisive requisite of social development, the topic of the last symposium he sponsored in October 2004

• preverbal communication, as a condition for early speech promotion, especially for infants with impaired hearing,

• the plasticity of the infant's brain as a neurobiological basis for early health promotion,

• enriching integration of infant and child as part of a socially intact community,

• preventive medical-check ups aiming at an early diagnosis of abnormality,

• earliest diagnosis of risks as a condition of PREhabilitation – which he called rehabilitation, to gain a financial niche for his actions in existing laws.

Hellbrügge's conference on chronomes 14 showed advanced chronobiologic and chronomic follow-ups on what he had discovered many decades earlier 6768. His contributions encouraged further investigations. Furthermore a cosmic view, visualized already by Bernhard de Rudder 69, another chronobiologically active predecessor of Theo in pediatrics in Munich, is being added to child development in health and disease 14. Preventive pediatrics can gain in Theo's footsteps a thoroughly grounded, scientific, biological yet also transdisciplinary basis. Theo's social pediatrics focuses upon the obviously handicapped child. A follow-up could focus on risks that are not obvious but may be detected chronomically as alterations of blood pressure and heart rate series. These alterations represent greater dangers than hypertension itself 65707172. It is the pediatrician's opportunity to nip them in the bud in Theo's footsteps.
