Oral cancer prediction by noninvasive genetic screening

Oral squamous cell carcinomas (OSCCs) develop in genetically altered epithelium in the mucosal lining, also coined as fields, which are mostly not visible but occasionally present as white oral leukoplakia (OL) lesions. We developed a noninvasive genetic assay using next-generation sequencing (NGS) on brushed cells to detect the presence of genetically altered fields, including those that are not macroscopically visible. The assay demonstrated high accuracy in OL patients when brush samples were compared with biopsies as gold standard. In a cohort of Fanconi anemia patients, detection of mutations in prospectively collected oral brushes predicted oral cancer also when visible abnormalities were absent. We further provide insight in the molecular landscape of OL with frequent changes of TP53, FAT1 and NOTCH1. NGS analysis of noninvasively collected samples offers a highly accurate method to detect genetically altered fields in the oral cavity, and predicts development of OSCC in high-risk individuals. Noninvasive genetic screening can be employed to screen high-risk populations for cancer and precancer, map the extension of OL lesions beyond what is visible, map the oral cavity for precancerous changes even when visible abnormalities are absent, test accuracy of promising imaging modalities, monitor interventions and determine genetic progression as well as the natural history of the disease in the human patient.

How health care professionals confront and solve ethical dilemmas – a tale of two countries: Slovenia and Croatia

AimTo assess the differences in the way how Slovenian and Croatian health care professionals (HCPs) confront ethical dilemmas and perceive the role of hospital ethics committees (HECs).MethodsThis cross-sectional, survey-based study involved HCPs from three Slovenian and five Croatian university medical centers (UMC). The final sample sizes were 308 (244 or 79.2% women) for Slovenia and 485 (398 or 82.1% women) for Croatia.ResultsCompared with Croatian physicians, Slovenian physicians reported a higher share of ethical dilemmas regarding waiting periods for diagnostics or treatment, suboptimal working conditions due to interpersonal relationships in the ward, and end-of-life treatment withdrawal, and a lower share regarding access to palliative care and patient information protection. Compared with Croatian nurses, Slovenian nurses reported a lower share of ethical dilemmas regarding the distribution of limited resources, recognizing the patient’s best interests, and access to palliative care. Compared with Croatian other HCPs, Slovenian other HCPs reported a lower burden of ethical dilemmas regarding waiting periods for diagnostics or treatment, distribution of limited resources, and access to palliative care. When encountering an ethical dilemma, all HCPs in both countries would first consult their colleagues. Slovenian and Croatian HCPs recognized the importance of the HECs to a similar extent, but viewed their role differently.ConclusionCroatian and Slovenian HCPs are confronted with different ethical dilemmas and perceive the role of HECs differently.

An ethical dilemma arises when we are confronted with a situation with two morally justifiable solutions, none of which is entirely satisfactory (1). In the course of their daily work, health care professionals (HCPs) encounter a broad range of ethical dilemmas (2-4), which often result in a moral distress for HCPs (5,6). A critical requirement for a successful response to an ethical dilemma is a strong foundation in medical professionalism cultivated during medical training and consolidated during professional work experience and career development (7-9).Slovenia and Croatia, previously the westernmost republics of the former Yugoslavia and now European Union members, share the same historical, geopolitical, economic, and religious background. A recent survey in the largest Slovenian tertiary hospital, the University Medical Center Ljubljana, found that the most important contexts that give rise to ethical dilemmas among HCPs were waiting periods for diagnostics and treatment, suboptimal working conditions due to poor interpersonal relationships, and preserving patients'' dignity, while the least important contexts were biomedical research, organ transplantation, and vaccine hesitancy (10). A study at the University Medical Center Rijeka found similar main ethical dilemmas in Croatian nurses and physicians, which included limiting life-sustaining therapy, euthanasia, and physician-assisted suicide (11).Except these two studies, little to nothing is known about the ethical dilemmas of HCPs in Slovenia and Croatia. In response to this limited evidence, we conducted a prospective survey with a primary objective to assess the differences in the share of ethical dilemmas among different categories of HCPs (physicians, nurses, and other HCPs) in Slovenian and Croatian tertiary hospitals (university medical centers, UMCs). The UMCs were purposively selected because in this kind of hospitals, one encounters complicated cases usually referred from other health care institutions for complex diagnostic and therapeutic procedures, which can often raise ethical issues. The secondary objectives of our survey were to study differences in the opinion on the existence of standard procedures when HCPs are facing an ethical dilemma; to determine whom HCPs consult when facing an ethical dilemma; and to identify the opinion on the importance of hospital ethics committees (HECs) and their role in Slovenia and Croatia.

Chest wall metastasis of endometrial cancer: case report and review of the literature

Introduction: Endometrial cancer is the fourth most common female cancer and also distant metastases to the chest wall associated with these tumors are seen less common. Surgical treatment options for metastases of endometrial cancer are limited.

Case: A 57-year-old patient who underwent total abdominal hysterectomy?+?bilateral salpingo oophorectomy and received adjuvant chemotherapy for endometrioid-type adenocarcinoma of the endometrium and tuba is presented. The patient initially presented with pleural effusion 8 years ago and the tumor was detected while during etiologic screening. The patient had no problems after adjuvant chemotherapy and had been living in another city when she presented with a mass on the chest wall measuring 20?×?15?×?12?cm 8 years after the initial diagnosis and distant organ metastasis due to the first surgery was detected. The mass was first thought to be a sarcoma and the tru-cut biopsy revealed a metastatic lesion that was immunohistochemically similar to the first surgical specimen. The mass was resected with a wide radical excision and ‘no touch’ technique. The patient was then discharged with no postoperative complications.

Conclusion: Here in, a case with a distant organ metastasis due to an endometrioid-type adenocarcinoma is presented accompanied by literature data.

Increased risk of eating disorders in women with polycystic ovary syndrome: a case-control study

Abstract

Data on eating disorders in women with PCOS is insufficient. The objective of this case study was to examine the hypothesis that women with PCOS exhibit more impaired eating than healthy women. Women diagnosed with PCOS under the 2003 Rotterdam Diagnostic Criteria (n?=?40) were compared with a healthy control group (n?=?40). The groups also were divided into two as normal body weight and overweight/obese. The Eating Disorders Assessment Questionnaire (EDE-Q) and the Three Factor Eating Questionnaire (TFEQ-R21), were completed by all participants in order to evaluate eating behaviors in addition to eating disorders. Among the overweight/obese group, the average total and subscale scores of the EDE-Q as well as the total and sub-factor scores of the TFEQ-R21 were higher in women with PCOS compared to controls (p?<?.05). However, this statistically significant result was not shown among the women with normal weight (p?>?.05). In comparison to the controls, the PCOS women displayed higher values of the tool scores indicating abnormal restraint eating, body shape concern and weight concern subscale scores (p?<?.05). This result suggests that the evaluation of eating disorders should be added to routine screening and the monitoring of women with PCOS.
