Abstract Background: Coronary artery disease (CAD) detection in asymptomatic patients still remains controversial. The aim of our study was to evaluate the usefulness of ophthalmologic findings as predictors of the presence of CAD when added to cardiovascular classic risk factors (CRF) in patients with acute coronary cardiopathy suspicion. Methods: After clinical stabilization, 96 patients with acute coronary cardiopathy suspicion were selected and divided in two groups: 69 patients with coronary lesions and 27 patients without coronary lesions. Their 192 eyes were subjected to a complete routine ophthalmologic examination. Samples of tear fluid were also collected to be used in the detection of cytokines and inflammatory mediators. Logistic regression models, receiver operating characteristic curves and their area under the curve (AUC) were analysed. Results: Suggestive predictors were choroidal thickness (CT) (OR: 1.02, 95% CI: 1.01-1.03) and tear granulocyte colony-stimulating factor (G-CSF) (OR: 0.97, 95% CI: 0.95-0.99). We obtained an AUC of 0.9646 (95% CI: 0.928-0.999) when CT and tear G-CSF were added as independent variables to the logistic regression model with cardiovascular CRF: sex, age, diabetes, high blood pressure, hypercholesterolemia, smoking habit and obesity. This AUC was significantly higher (p=0.003) than the prediction derived from the same logistic regression model without CT and tear G-CSF (AUC=0.828, 95% CI: 0.729-0.927). Conclusions: CT and tear G-CSF improved the predictive model for CAD when added to cardiovascular CRF in our sample of symptomatic patients. Subsequent studies are needed for validation of these findings in asymptomatic patients.

Abstract Objective To investigate pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) safety and efficacy in preventing hematological toxicity during concurrent chemoradiotherapy (CCRT) for small-cell lung cancer (SCLC). Methods We retrospectively assessed 80 SCLC patients treated with CCRT from January 2013 to December 2018 who received PEG-rhG-CSF within 48 hours after the end of chemotherapy, defined as prophylactic use, as the experimental group. An additional 80 patients who were not treated with PEG-rhG-CSF were matched 1:1 by the propensity score matching method and served as the control group. The main observations were differences in hematological toxicity, neutrophil changes, febrile neutropenia (FN) incidence and adverse reactions. Progression-free survival (PFS) and overall survival (OS) were analyzed with regular assessment and follow-up. Results The leukocyte, neutrophil, erythrocyte, and platelet counts and hemoglobin level decreased after CCRT, but the experimental group had slightly higher leukocyte and neutrophil counts than the control group (P<0.05). The incidences of grade III-IV leukopenia (18.75% vs. 61.25%) and neutropenia (23.75% vs. 67.5%) in the experimental group were significantly lower than those in the control group (P<0.05). The absolute neutrophil count was 4.17±0.79 on day 1 and peaked (6.81±2.37) on day 10 in the experimental group; the value in the control group was 2.81±0.86 on day 1. It decreased significantly and reached the minimum (0.91±0.53) on day 10 (P<0.05). The experimental group had a lower FN incidence than the control group (P<0.05). There was also no significant acute esophagitis or pulmonary toxicity. The treatment had no significant effect on PFS (11.4 vs. 8.7, P=0.958) or OS (23.9 vs. 17.3, P=0.325) over an 18.6-month median follow-up time. Conclusion PEG-rhG-CSF has good efficacy and safety in preventing hematological toxicity in SCLC patients during CCRT and has no significant effects on PFS or OS.

It has been reported that chemotherapy drugs and granulocyte colony-stimulating factor (G-CSF) administered on the same day can aggravate neutropenia. In the present study, we investigated the safety of pegfilgrastim during bleomycin, etoposide, and cisplatin (BEP) therapy. This single-center retrospective study, including 137 cycles of BEP therapy for germ cell tumors between January 2008 and April 2021, investigated safety. Short-acting G-CSF was used for 84 cycles and pegfilgrastim was used for 53 cycles. In the pegfilgrastim group, neutrophil count at nadir was significantly higher than in the G-CSF group (median 1,650/μl and 680/μl, respectively). The incidence of grade 3–4 neutropenia was significantly higher and the duration longer in the G-CSF group. Also, there was no significant difference in the incidence of febrile neutropenia. In conclusion, concomitant use of pegfilgrastim during BEP therapy did not increase neutropenia and was effective in terms of safety.

A disparate group of rare hematological diseases characterized by impaired maturation of neutrophil granulocytes defines congenital neutropenias. Neutropenic patients are prone to recurrent infections beginning in the first months of life. Of interest is “cyclic neutropenia”, an ultra-rare disorder revealed by sinusoidal variations of the neutrophil count and periodically-recurring infections every 21 days. Diagnosis of these disorders is frequently obscured by the multiple causes of recurrent fevers in children. Aim of this overview is to outline the physical assessment of children presenting with early-onset symptomatic neutropenia, identify the disease between the many medical conditions and even emergencies which should enter in differential diagnosis, hint at the potential management with granulocyte-colony stimulating factor, define the risk of evolution to hematologic malignancy, and summarize inter-professional team strategies for improving care coordination and outcomes of such patients.

ObjectiveTo investigate the effect of two treatments on the outcome of freeze-thaw embryo transfer for pregnancy assistance in thin endometrium.MethodsA retrospective study was conducted on 66 patients who failed in the first cycle treated in the reproductive medicine center of the Second Hospital of Hebei Medical University from January 2018 to December 2019. Granulocyte colony stimulating factor (G-CSF) was used through cavity infusion in one group (n=25, and growth hormone (GH) was subcutaneously injected in the group (n=41). The clinical data of the two groups were compared, including morphology and thickness of the endometrium, biochemical pregnancy rate, clinical pregnancy rate, implantation rate, miscarriage rate, and live birth rate in each period of the hormone replacement cycle.ResultsThere was no significant difference in age, BMI, AMH, FSH, LH, E2, infertility years, number of transferred embryos, basal endometrium, and thickness of endometrium on the day of P administration before and after treatment (P&gt; 0.05). After treatment, compared to the GH group, the G-CSF group presented higher biochemical pregnancy rate (56% versus 48.8%; P=0.569), clinical pregnancy rate (52% versus 46.3%; P=0.655), implantation rate (34.8% versus 27.5%; P=0.391), and live birth rate (40% versus 31.7%; P=0.493), but the differences were not statistically significant (P &gt; 0.05). On the 5th day of treatment, the endometrial thickness in the G-CSF group was thinner than that in the GH group (4.83 ± 0.85 versus 5.75 ± 1.27; P&lt; 0.05), but it had no correlation with pregnancy outcome (P &gt; 0.05). There was no significant difference in endometrial thickness between the two groups on the 7th, 9th day of treatment and the day of P administration (P &gt; 0.05). On the 5th day of treatment, the proportion of endometrial type A morphology in the GH group was significantly higher than that in the G-CSF group (P &lt; 0.05), while the type B morphology in the G-CSF group was significantly higher than that in the GH group (P&lt; 0.05).ConclusionAlthough G-CSF and GH may not have a role in increasing endometrium, both of them can improve the pregnancy outcomes of patients with thin endometrium in the FET cycle. And the effects of the two treatments were similar.
