“…The analysis also found a significant increase in relative risk on Monday, and in the morning from 6 am to noon. As with Shuhaiber [12] the weekly and circadian variation was not easily explainable but serves to emphasize that such variations can be observed.…”

“…Other chronobiological themes have been examined in STADs. Recently, Shuhaiber et al [12] examined the impact of the lunar cycle on mortality and length of stay following surgical repair of STAD. Season did not have a significant impact on survival, but the lunar cycle, specifically the Full moon, impacted the data in six month blocks, the mirror image results are strikingly seen (Figure 2).…”

Background: Seasonal variations of Stanford Type A dissections (STADs) have been previously described in the Northern Hemisphere (NH). This study sought to determine if these variation are mirrored in the Southern Hemisphere (SH). Methods: Data from patients treated surgically for STADs were retrospectively obtained from existing administrative and clinical databases from NH and SH sites. Data points of interest included age, sex, date of dissection, and 30-day mortality. The dates of dissections (independent of year) were then organized by season. Results: A total of 1418 patients were identified (729 NH and 689 SH) with complete data available for 1415; 896 patients were male with a mean age was 61 ± 14 years, and the overall 30-day mortality was 17.3%. Comparison of NH and SH on a month-to-month basis demonstrated a 6-month phase shift and a significant difference by season, with STADs occurring predo minantly in the winter and least in the summer. De composition of the monthly incidence using Fourier analysis revealed the phase shift of the primary harmonic to be -21.9 and 169.8 degrees (days), respectively, for NH and SH. The resultant 191.7 day difference did not exactly correspond to the anticipated 6-month difference but was compatible with the original hypothesis. Conclusion: Chronobiology plays a role in the occurrence of STADs with the highest occurrence in the winter months independent of the hemisphere. Season is not the predominant reason why aortas dissect, but for patients at risk, the increase in systemic vascular resistance during the winter months may account for the seasonal variations seen.

“…In a retrospective investigation of 15,985 patients with acute myocardial infarction, Wende et al observed a possible cardioprotective time of three days after a new moon [ 17 ]. The odds of death were reduced at full moon in 210 patients who had undergone repair for dissection in the ascending aorta [ 18 ]. A significantly higher number of admissions were noted at full moon in 7219 patients with medically unexplained acute stroke symptoms [ 1 ].…”

Purpose Popular beliefs exert an impact of lunar phases on elective surgery. The aim of our study was to evaluate potential correlations between complications in cataract surgery and the phases of the moon during its passage through the zodiac and Fridays that fall on the 13th. Methods Patients with complications during cataract surgery were extracted retrospectively from the clinical database from 2010 to 2014. The dates of surgeries were viewed in relation to the phase and the position of the moon (sign of the zodiac). Results Of 16,965 cataract surgeries, 132 eyes developed complications. 0.70% developed complications with a waxing moon, and 0.87% with a waning moon (p = 0.745). After Bonferroni correction, there were no statistically significant differences between the numbers of complications under the different signs of the zodiac and no complications on Fridays that fell on the 13th. Conclusions The analysis of “non-moon-fitting days” for surgery showed quantitative differences, without statistically significant findings. Our results revealed more complications when the moon was waning, which is in contrast to esoteric belief. Patients may be informed that phases of the moon, signs of the zodiac, or a particular date will have no impact on their surgeries.

“…They were diagnosed by specialist cardiologist and they detected that AMI occurs during resting position or bed rest position. Another study tried to identify the effects of the lunar cycle and seasonal variation on ascending aortic dissection surgery outcomes [14] they also applied these factors on risk adjusted hospital mortality and the length of stay followed by surgery for survivors. They chose different criteria for their investigation like first they want to co-relate full moon and seasonal variation, demographic and patient risk varieties and made a model that controls demographic risk factor of people like age, different kind of diseases (diabetes mellitus, hypertension).…”

This review is an attempt to consolidate the earlier studies on this subject and to get a broad based idea if there exists any relationship between full moon and various physiopsycological aspects on human like behavior, sleep cycle, cardiovascular system, endocrine system, birthrate, reproductive system. MethodologyData were collected from review of literatures from various scientific studies conducted so far globally. To meet our objectives, we try to do a study and see what actually occurs in the human body during full moon. To find out the related up-to-date topics we searched through PUB Med central, Goggle Scholar and related bibliographic databases. Only peer reviewed articles were chosen which were supposed to be of high quality. Database was created in the Endnote software and full text articles were collected by Endnote software. If there was a lack of information we contacted the corresponding authors for further clarification.
