Drug commonly used as antidepressant helps fight cancer in mice
A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain ’s “happiness hormone.”A new study by UCLA researchers suggests that those drugs, commonly known as MAOIs, might have another health benefit: helping the immune system attack cancer. Their findings are reported in two papers, which are published in the journals Science Immunology and Nature Communications.“MAOIs had not been linked to the immune system’s response to cancer before,” saidLili Yang, senior author of the study and a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. “What’s especially exciting is that this is a very well-studied and safe class of drug, so repurposing it for cancer isn’t as challenging as developing a completely new drug would be.”Recent advances in understanding how the human immune system naturally seeks out and destroys cancer cells, as well as how tumors try to evade that response, has led to new cancer immunotherapies — drugs that boost the immune system’s activity to try to fight cancer.In an effort to develop new cancer immunotherapies, Yang and her colleagues compared immune cells from melanoma tumors in mice to immune cells from cancer-free animals. Immune cells that had infiltrated tumors had much higher activity of a gene called monoamine oxidase A, o...
Conclusion: This article outlines the evaluation of a new program demonstrating that medical oncology practices can make improvements in the care of their underserved populations if provided with the proper tools, methods, and coaching. The use of formative evaluation methodology also identified opportunities for improvement and ultimately resulted in additional funding for more practices to participate in the program.
We present a case of a 38-year-old man with Fitzpatrick skin type IV with an asymmetric black papule showing clinical and dermoscopic features of both melanoma and SK. Reflectance confocal microscopy (RCM) and dynamic optical coherence tomography (d-OCT) were used for further evaluation. RCM revealed acanthotic epidermis with a mixed honeycomb and cobblestone pattern, polycyclic bulbous rete ridges, and bright plump cells within entrapped, edged, dermal papillae, compatible with pigmented SK. Also noted were a population of fairly uniform bright dendritic cells scattered quite evenly at all levels of the epidermis and the ...
Abstract: The foreign body reaction (FBR) is a well-documented immune reaction. Much of the literature on FBRs has focused on minimizing this immune response to mitigate the impact on medical implants. Here, we present a case that illustrates a serendipitous oncologic outcome from an FBR. A 54-year-old man presented with an aggressive basal cell carcinoma (BCC). At the first resection, he had broadly positive surgical margins. The surgical wound was temporized with a polyurethane wound vacuum assisted closure (VAC) device. He was lost to follow-up having retained a VAC sponge for a total of 12 weeks. A wide re-resectio...
We report a third patient with distinctive, generalized atrophic macules that developed after a morbilliform eruption during a clinical trial for treatment of metastatic pancreatic adenocarcinoma. Histopathological findings demonstrated diminished elastic fibers in the papillary dermis, associated with a histiocyte-rich infiltrate and increased dermal mucin, features that should clue the dermatopathologist to this condition.
Abstract: Human papillomavirus (HPV) is a leading cause of cancer. Increasing HPV vaccination recommendations by primary care providers to patients decreases the burden of this viral infection. Providers need to be educated about this condition and the available options for immunization to feel confident in making strong recommendations and thereby increase HPV immunization rates.

DR ELLIE CANNON: Anxiety and depression makes tinnitus (file photo) much worse, and it's common for people with dementia to suffer both.
Finding a humorous angle to some of my darkest episodes – and sharing them with strangers – was strangely cathartic“Have you gone mad?” asked one friend. “You’re so brave. I could never do that. Wouldn’t meditation be wiser?” said another. For someone with a long history of depression and anxiety, plus a morbid fear of public speaking, taking up standup comedy might seem like a masochistic decision. Yet to me it makes perfect sense. Excruciating fear of failure is at the heart of most people’s aversion to attempting to make a room full of strangers laugh. But controllin...
Diseases linked to vitamin D deficiency include cardiovascular disease, diabetes and cancer.
I started M1 two months ago and had a good start. However, this past three weeks I have been feeling like I am slipping into a bout of depression/anxiety. I am having trouble focusing during lectures/self-study, and after having 8 hours of classes every day I have been feeling too exhausted at night to do any meaningful studying. I have trouble falling asleep so I get more exhausted day by day. I have stopped exercising. I don't have the social energy to talk with any classmates. I feel so... Read more
