Glacial Climate

Before the last meeting of the British Association, held in Liverpool, Professor Edward Hull presented a paper upon “Another Possible Cause of the Glacial Epoch.”inthat paper, Professor Hull applied the writer's work on the “Reconstruction of the Antillean Continent,” which brought together evidence of great continental elevation. This elevation and its effects upon the ocean-currents, in diverting them from the West Indian regions, with the consequent reduction of their temperature as they reach the northern latitudes in conjunction with the elevation of the land, were thought by Professor Hull to be sufficient causes for the production of the glacial climate over temperate regions in late geological times. The writer has hitherto never applied his observations on high continental elevation to climatic changes; but in this paper he proposes to extend briefly his researches from the Antillean region to the higher latitudes of America and the North Atlantic regions. Something has also been learned of the date of the great elevation; consequently inferences may be drawn as to climatic changes.

AbstractGiven increasing demand for primary knee arthroplasties, revision surgery is also expected to increase, with periprosthetic joint infection (PJI) a main driver of costs. Recent data on national trends is lacking. We aimed to assess trends in PJI in total knee arthroplasty revisions and hospitalization costs. From the National Inpatient Sample (2003–2016), we extracted data on total knee arthroplasty revisions (n = 782,449). We assessed trends in PJI prevalence and (inflation-adjusted) hospitalization costs (total as well as per-day costs) for all revisions and stratified by hospital teaching status (rural/urban by teaching status), hospital bed size (≤299, 300–499, and ≥500 beds), and hospital region (Northeast, Midwest, South, and West). The Cochran–Armitage trend test (PJI prevalence) and linear regression determined significance of trends. PJI prevalence overall was 25.5% (n = 199,818) with a minor increasing trend: 25.3% (n = 7,828) in 2003 to 28.9% (n = 19,275) in 2016; p < 0.0001. Median total hospitalization costs for PJI decreased slightly ($23,247 in 2003–$20,273 in 2016; p < 0.0001) while median per-day costs slightly increased ($3,452 in 2003–$3,727 in 2016; p < 0.0001), likely as a function of decreasing length of stay. With small differences between hospitals, the lowest and highest PJI prevalences were seen in small (≤299 beds; 22.9%) and urban teaching hospitals (27.3%), respectively. In stratification analyses, an increasing trend in PJI prevalence was particularly seen in larger (≥500 beds) hospitals (24.4% in 2003–30.7% in 2016; p < 0.0001), while a decreasing trend was seen in small-sized hospitals. Overall, PJI in knee arthroplasty revisions appears to be slightly increasing. Moreover, increasing trends in large hospitals and decreasing trends in small-sized hospitals suggest a shift in patients from small to large volume hospitals. Decreasing trends in total costs, alongside increasing trends in per-day costs, suggest a strong impact of length of stay trends and a more efficient approach to PJI over the years (in terms of shorter length of stay).

Background: Infertility is defined as the inability to conceive after at least one year of unprotected intercourse. It is a complex disorder with significant medical, psychosocial, and economic problems. In about one third of couples are infertile. Approximately 167 million married women aged 15-49 years in developing countries were infertility. The present study aimed to determine the most common causes of female infertility in patients who visiting the National Ayuvedic Teaching Hospital, Borella, Sri Lanka. Methods: In this study 635 infertile (primary and secondary) women were selected to determine the causes of infertility. The subjects were selected from the gynecology clinic, between the periods of February 2015 to March 2016. The data were gathered using a questionnaire; and after that proper statistical method was applied to analyze the data. Results: From the results age between 28-37 years (37.16%) are more prevalent to infertility and the causes of infertility are mainly due to anovulatory cycle (31.18%) and menstrual irregularities (19.21%). BMI also one of the significant cause for infertility. Conclusion: Therefore, identifying the risk factors and proper treatment on time along with policy makers providing facilities to resolve the infertility could possible diverse this alarming increasing trend of infertility.
