Primary Care Delivery Perceptions and Their Associations with Physician and Patient Gender.

INTRODUCTION: We aim to survey patients' opinions on perceived differences in patient care delivered by male and female physicians. METHODS: Patients of primary care practices at Mayo Clinic, Arizona completed a survey sent through the electronic health record. The survey evaluated opinion regarding their primary care physician (PCP)'s overall healthcare provision capabilities and any perceived differences based on gender. RESULTS: 4983 patients' responses were included in final analysis. Compared to male patients, most female patients preferred to have a female PCP (78.1% vs. 32.7%, p < 0.01). Having a preference for female physicians was correlated with higher overall opinion of female physicians. The majority of male patients did not hold a difference in opinion regarding male versus female physicians (p < 0.01). Male patients were half as likely to have a better opinion and nearly 2.5 times more likely to have a worse opinion of female physicians (p < 0.01) compared to female patients. Patients preferring female physicians were nearly 3 times more likely to have a better opinion of female physicians compared to patients with no preference (p < 0.01). CONCLUSION: In a primary care setting, majority of female patients compared to male patients preferred female physicians as their PCP and had higher opinion of the care delivery of female physicians. These findings may influence how practices should assign primary care physicians to new patients and add underlying context to patient satisfaction ratings.

Unusual and rare cause of abdominal pain: abdominal desmoid fibromatosis masquerading as a postoperative haematoma.

Desmoid fibromatosis is a rare connective tissue malignancy. It can occur in a variety of locations, including the abdominal wall, extremities and abdominal cavity. There has been an association with development in a prior surgical scar. Common symptoms can vary depending on the location and can include being painless to having pain at the site, functional impairment and bowel obstruction from intra-abdominal masses. In the following report, we discuss a case in which a patient's abdominal pain was attributed to a postoperative haematoma based on CT radiographic features; however, further work-up and biopsy yielded desmoid fibromatosis, a rare locally aggressive malignancy.

Patient-Derived Organotypic Epithelial Rafts Model Phenotypes in Juvenile-Onset Recurrent Respiratory Papillomatosis.

Juvenile-onset recurrent respiratory papillomatosis (JoRRP) is driven by human papillomavirus (HPV) low-risk strains and is associated with significant morbidity. While previous studies of 2D cultures have shed light on disease pathogenesis and demonstrated the utility of personalized medicine approaches, monolayer cultures lack the 3D tissue architecture and physiology of stratified, sequentially differentiated mucosal epithelium important in RRP disease pathogenesis. Herein we describe the establishment of JoRRP-derived primary cell populations that retain HPV genomes and viral gene expression in culture. These were directly compared to cells from matched adjacent non-diseased tissue, given the known RRP patient-to-patient variability. JoRRP papilloma versus control cells displayed decreased growth at subconfluency, with a switch to increased growth after reaching confluency, suggesting relative resistance to cell-cell contact and/or differentiation. The same papilloma cells grown as 3D organotypic rafts harbored hyperproliferation as compared to controls, with increased numbers of proliferating basal cells and inappropriately replicating suprabasal cells, mimicking phenotypes in the patient biopsies from which they were derived. These complementary model systems provide novel opportunities to elucidate disease mechanisms at distinct stages in JoRRP progression and to identify diagnostic, prognostic and therapeutic factors to personalize patient management and treatment.

The distribution of novel biomarkers in carcinoma-in-situ, microinvasive, and squamous cell carcinoma of the uterine cervix.

Importin-ß, exportin-5, p16, Ki-67, Mcl1, PDL1, and cFLIP are each over-expressed in the majority of CIN 1 lesions. These biomarkers, plus HPV E6/E7 RNA, were analyzed in carcinoma-in-situ (CIS), microinvasive, and squamous cell carcinoma (SCC) of the uterine cervix and cervical carcinoma cell lines. Only p16 and Ki-67 continued to be over-expressed in CIS, with a concomitant marked increase in E6/E7 RNA. There was a highly significant increase in PDL1 expression and decrease in Ki-67 (each p < 0.001) in microinvasive cancer compared to CIS whereas p16 and E6/E7 remained stable. As the lesion progressed to SCC, p16 and E6/E7 RNA remained strongly overexpressed with a concomitant over expression of importin-ß and Ki67. HPV positive Caski cells showed significant elevations of p16, importin-ß, exportin-5 and PDL1 compared to the HPV negative cervical cancer cell line C33A, consistent with viral induction of these biomarkers. The data suggest that PDL1 may be a useful biomarker to differentiate CIS from microinvasive cancer and, thus, anti-PDL1 therapy may inhibit the progression of CIS to the invasive stage.
