Input: Consider Input: Context: Patient experience is an essential component of quality care. Few studies have comprehensively evaluated patient experiences of abortion care. The objectives of this study were to describe women's experiences of abortion care in their own words, and to determine themes across patient experiences.", 'Data for this thematic analysis, a qualitative method that allows for the identification, analysis, and report of patterns or themes within data, come from a larger study of safety and quality of aspiration abortion care across 22 clinical sites. Participants completed an abortion experience survey including fixed choice questions and an open-ended question: "Is there anything you would like to tell us about your experience?" The data were then categorized by responses to another survey question: "Overall, was your experience about, better, or worse than you expected?"', 'A total of 5,214 responses were analyzed. Women reported positive abortion care experiences with the majority of women rating their experience as better than expected (n = 3,600). Two major themes that emerged from the data include clinic- and patient-level factors that impact how patients rate their experiences. Analysis of the responses categorized in the worse than expected group (n = 136) found that women primarily faulted clinic-level factors for their negative experiences, such as pain control and management, and wait time for appointments and in clinic.
Answer: This analysis highlights specific areas of abortion care that influence patients' experience. The few women who were disappointed by care in the clinic tended to fault readily modifiable clinical factors, and provided suggested areas of improvement to enhance positive experiences related to their abortion care.

Output: Do women know best -- findings from a thematic analysis of 5,214 surveys of abortion care experience?


Input: Consider Input: Context: The present study was undertaken to determine whether exposure of the sclera to prostaglandin (PG)F(2alpha) or to the PGF(2alpha) analogue latanoprost acid alters mRNA for matrix metalloproteinases.', 'Fifteen human eye bank eyes were studied. Circular pieces of sclera were either immediately preserved in a stabilization reagent or cultured in low-serum DMEM/F-12 medium. The cultures were treated for 24 hours with medium supplemented with PGF(2a), latanoprost acid, or vehicle. Total RNA was then isolated, and the expression of mRNA for matrix metalloproteinase (MMP)-1, -2, -3, -8, -9, -10, and -12 were determined by real-time PCR. All results were normalized according to the GAPDH mRNA in each sample. Altered mRNA expression after PG treatments also was evaluated with microarrays containing 19 MMP genes and 4 tissue inhibitor of matrix metalloproteinase (TIMP) genes.', 'Real-time PCR results showed that 24 hours of exposure to 100 nM PGF(2alpha) significantly increased mRNA for MMP-1 and -9 (P < 0.06 Wilcoxon test) and that exposure to 100 nM latanoprost acid significantly increased mRNA for MMP-9 (P < 0.06 Wilcoxon test). Array analysis demonstrated increases of MMP-3 and -10 mRNA after exposure to 100 nM latanoprost and further increases after exposure to 200 nM latanoprost. The array results also showed that latanoprost induced dose-dependent increases in the expression of TIMP-1, -2, and -3 mRNA in the scleral cultures.
Answer: PGF(2alpha) and latanoprost acid induce coordinated alterations of MMP gene transcription in scleral organ cultures. These results indicate that PGs can directly trigger MMP gene transcription changes within the sclera. These changes support a role for increased MMPs in the enhancement of uveoscleral outflow that occurs after topical treatment with latanoprost.

Output: Do prostaglandin FP agonists alter metalloproteinase gene expression in sclera?


Input: Consider Input: Context: Extracellular vesicles (EVs), including circulating microvesicles (MVs) or mi- croparticles (MPs) and exosomes, derived from cells or platelets are present in the peripheral blood and are important elements involved in the activation of the coagulation system, transport of macromolecules and intercellular communication. In patients with vascular complications (including diabetes), the number of EVs is significantly increased during the acute phase of the disease. However, less is known about EVs release in the chronic state of diabetes.', 'To analyse the profile of inflammatory cytokines and angiogenic factors in EVs in diabetic patients with ocular and vascular complications.', 'The study included patients with diabetes and varying degrees of ocular complications including retinopathy (n = 48) and the control group (n = 13). EV-enriched and EV-depleted fractions were obtained from platelet-poor plasma by means of the centrifugation method (16 000 g, for 90 min). In screening, the profile of cytokines with pro-angiogenic effects was preliminary assessed using the protein microarray technology for controlled diabetic patients - CD, uncontrolled diabetic patients - UD and for the control group. In all patients, concentrations of cytokines: RANTES (Regulated on Activation, Normal T-cell Expressed and secreted) and Ang-2 (angiopoietin-2) were assayed using the ELISA method. Common blood and biochemical tests were performed.', 'In patients with diabetes, analysis of supernatant revealed significantly increased concentrations of basic fibroblast growth factor (bFGF) and soluble receptor for vascular endothelial growth factor 2 (V-EGFR2) when compared to the control group: 49 (10.5-122) vs. 24 (2-72.5) SD (p = 0.03) and 260 (195.5-351) vs. 360 (256-461.5) SD (p = 0.01). In UD patients, concentrations of RANTES, angiostatin, tumor necrosis factor-α (TNF), and tissue inhibitors of metalloproteinase 1 and 2 (TIMP1 and TIMP2) were relatively higher in the EV-enriched fraction when compared to the EV-depleted fraction. Post hoc analysis revealed significant differences between UC patients and the control group in RANTES (16.73 (14.41-18.93) vs. 14.62 (12.37-15.28) mg/ml; p = 0.0235) and Ang-2 (2.76 (2.23-4.64) ng/ml vs. 1.74 (1.54-1.93); p = 0.0316) concentrations. These analyses did not reveal any significant differences in RANTES and Ang-2 concentrations between CD patients and the control group.
Answer: The profiles of cytokines and angiogenic factors in EVs are significantly increased in patients with diabetes. Also, the formation of specific cytokines related to EVs is strongly influenced by disease duration and successful treatment. EVs seem to be the conveyors of upregulated cytokines and angiogenic agents in diabetic patients.


Output: Do extracellular vesicles participate in the transport of cytokines and angiogenic factors in diabetic patients with ocular complications?
