Co-occurrence of thyroid and breast cancer is associated with an increased oncogenic SNP burden.

BACKGROUND: Epidemiological evidence suggests that synchronous or metachronous presentation of breast and thyroid cancers exceeds that predicted by chance alone. The following potential explanations have been hypothesized: common environmental or hormonal factors, oncogenic effect of the treatment for the first cancer, closer follow-up of cancer survivors, shared underlying genetic risk factors. While some cases were found to be related to monogenic disorders with autosomal inheritance, the genetic background of most cases of co-occurring breast and thyroid cancer is thought to be polygenic. METHODS: In this retrospective case-control study we compared the genetic profile of patients with a history of breast cancer (n = 15) to patients with co-occurring breast and thyroid cancer (n = 19) using next generation sequencing of 112 hereditary cancer risk genes. Identified variants were categorized based on their known association with breast cancer and oncogenesis in general. RESULTS: No difference between patients with breast and double cancers was observed in clinical and pathological characteristics or the number of neutral SNPs. The unweighted and weighted number of SNPs with an established or potential association with breast cancer was significantly lower in the group with breast cancer only (mean difference - 0.58, BCa 95% CI [- 1.09, - 0.06], p = 0.029, and mean difference - 0.36, BCa 95% CI [- 0.70, - 0.02], p = 0.039, respectively). The difference was also significant when we compared the number of SNPs with potential or known association with any malignancy (mean difference - 1.19, BCa 95% CI [- 2.27, - 0.11], p = 0.032 for unweighted, and mean difference - 0.73, BCa 95% CI [- 1.32, - 0.14], p = 0.017 for weighted scores). CONCLUSION: Our findings are compatible with the hypothesis of genetic predisposition in the co-occurrence of breast and thyroid cancer. Further exploration of the underlying genetic mechanisms may help in the identification of patients with an elevated risk for a second cancer at the diagnosis of the first cancer.

Telepsychotherapy and the Therapeutic Relationship: Principles, Advantages, and Case Examples.

OBJECTIVE: As the use of technology continues to expand within our mental healthcare system, there has been an increasing interest in conducting psychotherapy online using videoconferencing. Literature pertaining to telepsychotherapy has explored possible drawbacks of this modality on the therapeutic relationship, although several studies have shown that the efficacy of online psychotherapy is equivalent to in-person approaches. Little is written about the potential advantages to the psychotherapeutic relationship when psychotherapy is carried out over videoconferencing. METHODS: The available literature was reviewed, as were the general principles of telepsychotherapy and the therapeutic relationship, followed by a more in-depth consideration of patient populations for whom telepsychotherapy may offer distinct advantages. RESULTS: The current literature, as well as our own clinical experience, suggests that telepsychotherapy may be effective for a broad range of patients, and it may offer distinct advantages in the building of a trusting psychotherapeutic relationship. CONCLUSION: Telepsychotherapy offers a novel way to reach and form strong psychotherapeutic relationships with many different types of patients, and it may foster therapeutic intimacy in ways that in-person psychotherapy cannot. More research is needed to further explore this unique modality.

Ethical Considerations Regarding Internet Searches for Patient Information.

In 2010, the American Medical Association developed policies regarding professionalism in the use of social media, but it did not present specific ethical guidelines on targeted Internet searches for information about a patient or the patient's family members. The American Psychiatric Association (APA) provided some guidance in 2016 through the Opinions of the Ethics Committee, but published opinions are limited. On behalf of the APA Ethics Committee, the authors developed a resource document describing ethical considerations regarding Internet and social media searches for patient information, from which this article has been adapted. Recommendations include the following. Except in emergencies, it is advisable to obtain a patient's informed consent before performing such a search. The psychiatrist should be aware of his or her motivations for performing a search and should avoid doing so unless it serves the patient's best interests. Information obtained through such searches should be handled with sensitivity regarding the patient's privacy. The psychiatrist should consider how the search might influence the clinician-patient relationship. When interpreted with caution, Internet- and social media-based information may be appropriate to consider in forensic evaluations.
