Factors related to help-seeking for cancer medical care among people living in rural areas: a scoping review.

Despite the importance of timely diagnosis and access to treatment, previous studies have not adequately explored help-seeking behavior in cancer treatment among rural and remote residents. The barriers preventing help-seeking behavior also remain unclear. To address this research gap, this study conducted a scoping review to suggest a framework for eliminating barriers and facilitating help-seeking for cancer treatment among rural and remote residents. To conduct the scoping review, three English medical databases (PubMed, MEDLINE, and CINAHL) were examined for the keywords "rural," "remote," "cancer," and "help-seeking." The research objectives and study designs, participants, and excerpts describing help-seeking of the selected papers were recorded in a data charting form. Descriptions of help-seeking behavior were organized and summarized according to their meaning and integrated into factors using thematic analysis. All extracted factors related to help-seeking were sorted into four main themes according to the Ecological Model of Health Behavior, the theoretical lens for this scoping review: (1) Intrapersonal; (2) Interpersonal; (3) Groups, culture, and organizations; and (4) Policy/environment. Factors were categorized as barriers and facilitators of help-seeking. A total of 13 papers were analyzed. Intrapersonal factors such as self-reliance, symptom appraisal, and fatalism, were identified as barriers to help-seeking, whereas presentation of abnormal and serious symptoms facilitated help-seeking. Interpersonal factors such as lack of understanding of family members, influence of surrounding people, role obligations, and lack of trust in experts hindered help-seeking, whereas understanding from surrounding people such as family and friends, promoted help-seeking. Groups, cultural, and organizational factors such as prejudice, social stigma, shame, lack of anonymity, and social norms acted as barriers to help-seeking. Policy-related barriers to help-seeking included lack of medical services and physical distance from medical institutions, leading to a time burden. The study discussed the identified factors from a rural context. Future studies should consider the identified barriers and facilitators according to the four main themes in rural areas when formulating interventions to promote help-seeking. Our findings can offer a theoretical foundation to develop actionable policies, preventive strategies, and relevant interventional tools that may facilitate oncological service utilization in rural areas.

Cytologic features of oral squamous cell carcinoma in an Indo-Pacific bottlenose dolphin (Tursiops aduncus): Papanicolaou stain and immunocytochemistry using liquid-based cytology.

Although oral cytology using Papanicolaou stain is useful for the early detection of oral premalignant lesions and squamous cell carcinoma (SCC) in people, little work has been conducted on this topic in veterinary medicine. This paper describes the features of oral cytology using Papanicolaou stain and immunocytochemistry on liquid-based cytology slides in a case of oral SCC in an Indo-Pacific bottlenose dolphin (Tursiops aduncus). In this case, dysplastic cells with koilocyte-like changes and SCC cells were identified using the Papanicolaou stain. These cells were positive for p53 using an immunocytochemistry analysis. A cytologic diagnosis of SCC was made. We believe that the early detection of premalignant oral lesions and SCC in dolphins can be significantly improved with cytology using liquid-based cytology, Papanicolaou staining, and immunocytochemistry.

Molecular Signature of Tumors with Monoallelic 13q14 Deletion: a Case Series of Spindle Cell Lipoma and Genetically-Related Tumors Demonstrating a Link Between FOXO1 Status and p38 MAPK Pathway.

Spindle cell/pleomorphic lipomas (SCLs), cellular angiofibromas (CAFs) and mammary-type myofibroblastomas (MFBs) are rare benign mesenchymal tumors with monoallelic 13q14 deletion. They are predicted to have a common pathogenic mechanism due to shared similar histological and immunohistochemical features; however, pathological consequences of monoallelic 13q14 deletion remain unknown. We previously reported a CAF case with monoallelic 13q14 deletion in which the tumor expressed decreased levels of FOXO1 and RB1, both of which were encoded in 13q14, and increased reactive oxygen species (ROS) levels. We further demonstrated the activation of p38 mitogen-activated protein kinase (p38 MAPK) pathway induced by oxidative stress. We hypothesized that SCLs, CAFs and MFBs would share common molecular signatures involving FOXO1, ROS and p38 MAPK and that their expression patterns were different from those tumors without monoallelic 13q14 deletion such as solitary fibrous tumors (SFTs). We compared the expression levels of FOXO1, RB1, ROS markers and several signal transduction factors between SCLs and SFTs. SCLs expressed decreased levels of FOXO1 and RB1, whereas SFTs showed no change. Both tumor types exhibited increased markers of ROS; however, nuclear localization of phosphorylated p38 was significantly more frequent in SCLs than that in SFTs, suggesting p38 MAPK activation by oxidative stress. SFTs showed lower p38 MAPK activity and higher ß-catenin expression, implying that oxidative stress was caused by increased cellular proliferation stress. Finally, CAFs and MFBs showed changes similar to those observed in SCLs. Overall, tumors with monoallelic 13q14 deletion showed shared molecular signatures that might be associated with pathogenesis.

Patients' help-seeking experiences and delaying in breast cancer diagnosis: A qualitative study.

AIM: To identify the influencing factors in help-seeking behavior by comparing delayers with non-delayers in Japanese female patients with breast cancer. METHODS: This is a descriptive qualitative study. A total of 21 female patients with breast cancer (nine delayers and 12 non-delayers) who were at least 3 months to 5 years postdiagnosis were recruited from two hospitals in Okinawa, Japan. Semistructured interviews were carried out and the results were analyzed by using a qualitative inductive approach. RESULTS: The comparison between the delayers and non-delayers showed eight barriers to help-seeking behavior that were unique to the delayers: (i) the appearance of symptoms that cannot be definitely linked to breast cancer; (ii) anxiety and fear; (iii) the necessity to prioritize the immediate needs of daily life; (iv) non-disclosure of the situation; (v) the view that medical care is a nuisance; (vi) a desire to surrender to the natural course of things; (vii) confidence that they would not develop cancer; and (viii) inaccessibility of medical facilities. A common trigger for help-seeking that was identified in both the delayers and the non-delayers was the presence of other persons who encouraged seeking a provider evaluation. CONCLUSION: The barriers to help-seeking that were found in this study (namely, the emotional reaction and difficult living conditions) are common worldwide. The Japanese patients with breast cancer in the sample tended to emphasize their relationship with family and friends in their help-seeking behavior, which is a common content in Japanese and other Asian cultures. Therefore, health professionals should assess the social conditions of their patients.

Esophageal Xanthoma: Presence of M2 Macrophages Suggests Association with Late Inflammatory and Reparative Processes.

Esophageal xanthoma is a rare lesion which is an asymptomatic small yellowish polyp, and most of the reported cases were solitary lesion. Histologically, aggregations of foam cells are found under the papillary hypertrophic squamous epithelium and the foam cells express CD68. The etiology of esophageal xanthoma is unknown. The focal irritation of the esophageal mucosa and infiltrated inflammatory cells are presumed to contribute to its pathogenesis. Although the pathogenesis may be associated with inflammation, the type and nature of the macrophages remain unclear. Here we report a 46-year-old male with esophageal xanthoma, which was incidentally found by endoscopy. Histologically, acute inflammation was not noted, and immunohistochemistry revealed that the foam cells seen in this case of esophageal xanthoma expressed increased levels of M2 macrophage markers. These findings suggest that esophageal xanthoma is associated with late inflammatory and reparative processes long after the initial inflammation of esophageal squamous epithelium.

CD10 expression in the neuroendocrine carcinoma component of endometrial mixed carcinoma: association with long survival.

BACKGOUND: Endometrial mixed carcinoma with the neuroendocrine carcinoma (NEC) component is rare and is believed to have a poor prognosis. CD10 expression is reported to be a favorable prognostic marker for some tumors such as B-lymphoblastic leukemia/lymphoma, but unfavorable for others. Here, we report the case of a 33-year-old woman diagnosed with endometrial mixed carcinoma with the NEC component expressing CD10 who showed a favorable outcome. CASE PRESENTATION: The patient presented with lumbago and brownish discharge from the genitals. Imaging modalities revealed a large exophytic mass in the uterine corpus, and a small one in the uterine cervix. Radical hysterectomy with bilateral salpingo-oophorectomy was performed. Microscopic examination of the endometrial and cervical masses revealed that the NEC component accounted for the maximum area in both masses. However, small areas in both lesions showed well differentiated endometrioid adenocarcinoma (WDEA) components, and histological transition between the two components was also observed. In addition to CD56 and synaptophysin expression, the NEC component was positive for CD10 but negative for estrogen receptor (ER), progesterone receptor (PgR), and carcinoembryonic antigen (CEA). In contrast, the WDEA component expressed both ER and PgR, but neither CD10 nor neuroendocrine markers were demonstrated. The CD10 and neuroendocrine markers clearly distinguished between the NEC and WDEA components. Furthermore, retained expression of phosphatase and tensin homolog (PTEN) and weak phosphorylated Akt expression were found, which were assumed to suppress the aggressive behavior of the tumor. The patient received postoperative chemotherapy and has survived without recurrence for 6 years after the operation. CONCLUSION: This is the first case of endometrial mixed carcinoma with the NEC component expressing CD10 that showed a long survival.

A case of catastrophic antiphospholipid syndrome presenting with acute respiratory distress syndrome as the initial manifestation.

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by a combination of arterial or venous thrombosis and recurrent fetal loss, accompanied by elevated titers of antiphospholipid antibodies (aPL). Catastrophic antiphospholipid syndrome (CAPS) is a small subset of APS characterized by widespread systemic thrombotic disease with multiorgan failure. We herein describe an autopsy case of CAPS who developed severe respiratory failure due to acute respiratory distress syndrome (ARDS) as the initial manifestation. Patients with APS may exhibit a broad spectrum of pulmonary diseases. ARDS is the common pulmonary complication in CAPS, although it rarely occurs in APS. Some mechanisms of ARDS in CAPS have been postulated but the precise mechanism is still not clearly understood. It is important to understand that APS or CAPS could be a cause of ARDS since ARDS might develop as the initial manifestation of APS or CAPS as seen in our case. Our case is interesting in that severe respiratory failure due to ARDS was the initial presentation of CAPS.

Signet-ring cell carcinoma of the esophagus associated with Barrett's epithelium: report of a case.

We herein report a case of infiltrative esophageal signet-ring cell carcinoma resembling gastric signet-ring cell carcinoma. Grossly, the tumor was a diffusely infiltrative carcinoma involving the lower esophagus measuring 11 cm in diameter. The tumor extensively metastasized to the cervical, mediastinal, and abdominal lymph nodes, and the patient died of peritonitis and pleuritis carcinomatosa soon after undergoing a radical esophagectomy. Histologically, the tumor was signet-ring cell carcinoma covered with normal squamous epithelium. However, the most superficial part of the tumor center contained a region of Barrett's mucosa with incomplete-type intestinal metaplasia and a well-differentiated adenocarcinoma component with goblet cells. The expression of cytokeratins 7 and 20 also indicated that both the Barrett's mucosa and the signet-ring cell carcinoma had an esophageal origin. Esophageal signet-ring cell carcinoma with diffuse infiltrative growth is quite rare, and may need a special treatment strategy because of its highly aggressive behavior and poor treatment outcome.

Diffuse hepatocellular calcification developing in a patient on chronic hemodialysis after ischemic hepatitis.

Diffuse hepatic calcification is a rare condition. Previous reports have described patients with end-stage renal disease who developed diffuse hepatic calcification after ischemic hepatitis caused by shock. We herein present a similar case. A 41-year-old man on chronic hemodialysis developed ischemic hepatitis due to shock induced by ventricular tachycardia, followed by progressive hepatic failure. Necropsy of the liver revealed diffuse hepatocellular calcification. Given the similarity by which our case and previously reported cases developed this rare condition, we postulate that chronic renal failure is involved in the pathogenesis of diffuse hepatic calcification.
