This May Be The 'Most Contaminated Killer Whale' On The Planet

Researchers in Scotland believe they’ve found one of the most contaminated killer whales on the planet. They fear members of the orca’s pod may also have sky-high levels of chemicals in their bodies that render them infertile, scientists at Scotland’s Rural College said in a news release this week. New analysis of a deceased adult female killer whale, named Lulu by researchers, shows that the animal’s blubber contained some of the highest levels ever recorded of polychlorinated biphenyls, or PCBs, a toxic chemical once pervasive in electrical components. The researchers called Lulu the “Scottish killer whale most contaminated on the planet.” PCBs are banned in the U.K. and the U.S. due to toxicity. But because the chemical is resistant to extreme temperatures and pressures, it takes a long time to break down. PCBs still exist in the environment, and have been known to leach from landfills into groundwater, according to the U.S. Environmental Protection Agency. Andrew Brownlow, head of the Scottish Marine Animal Stranding Scheme, told BBC News that the level of PCBs found in Lulu’s blubber was shockingly high ― an estimated 20 times the rate considered safe for cetaceans. High levels of the chemical are linked to poor health, including impaired immune function, infertility and increased susceptibility to cancers. “That puts her as one of the most contaminated animals on the planet in terms of PCB burden, and does...

Authors: Dolmans MM, Masciangelo R Abstract Improvements in cancer treatments have increased the chances of survival of young cancer patients, but have given rise to other issues, like premature ovarian insufficiency and infertility. Preservation and subsequent restoration of ovarian function in these patients is now possible thanks to ovarian tissue cryopreservation and transplantation. However, safety concerns about the possible presence of cancerous cells in the tissue to be cryopreserved must be addressed. Indeed, reimplantation of malignant cell-contaminated ovarian tissue could potentially lead to recurrence ...

ConclusionsIn this review, we summarize the roles of snails in the life cycles of the parasites they host, the worldwide distribution of parasite-transmitting snails, the epidemiology and pathogenesis of snail-transmitted parasitic diseases, and the existing snail control measures, which will contribute to further understanding the snail-parasite relationship and new strategies for controlling snail-borne parasitic diseases.

We present a case series of 2 sisters in their 20s who presented with isolated uterine leiomyomas and were found to carry a novel mutation for the fumarate hydratase gene. One patient was referred for treatment of infertility and recurrent miscarriages and the other was referred for acute symptomatic anemia due to myomas. Prompt diagnosis of hereditary leiomyomatosis renal cell cancer was made due to a high index of clinical suspicion based on early onset disease and familial clustering as well as characteristic pathologic findings on uterine leiomyoma surgical specimen. Timely diagnosis not only allowed for genetic counse...

CONCLUSION: Our results show that Epstein-Barr infection is possibly associated with autoimmune ovarian failure. The devastating impact on fertility in such disorder can be successfully avoided by in vitro maturation of oocytes from excised ovarian tissue. PMID: 29618356 [PubMed - in process]

Abstract Purpose To provide current recommendations about fertility preservation for adults and children with cancer. Methods A systematic review of the literature published from January 2013 to March 2017 was completed using PubMed and the Cochrane Library. An Update Panel reviewed the identified publications. Results There were 61 publications identified and reviewed. None of these publications prompted a significant change in the 2013 recommendations. Recommendations Health care providers should initiate the discussion on the possibility of infertility with patients with cancer treated during their reproductive...

The mean age of fathers in the United States is on the rise. Several reports have suggested that advanced paternal age increases the risk of cancer, psychiatric disease, chromosomal abnormalities, and failing grades in offspring, yet unlike for maternal age, little is known about the quantitative impact of older fathers on these diseases. We thus sought to model the increase in offspring disease between 1972 and 2015 attributable to demographic trends of increasing paternal age within the United States.

Testis cancer presents a unique problem in male fertility preservation. As many as 50-70% of patients diagnosed with testis cancer are subfertile at the time of diagnosis and up to 15% are azoospermic. Many patients will also require adjuvant radiotherapy or chemotherapy further complicating future fertility potential. In this video, we aim to provide a step-by-step guide to the performance of microsurgical onco-testicular sperm extraction (onco-TESE) in the setting of radical orchiectomy for testis cancer in an azoospermic patient.
