Introduction: Hip fractures are a worldwide public health issue associated with significant mortality. Previous Polish studies reported an increasing trend in the number of hip fractures for both men and women, although lower than most other European countries. Materials and Methods: The Polish National Database was analyzed to examine osteoporotic hip fractures in the population aged 50 and over. Hip fracture incidence, rate, one-year mortality, and postoperative length of hospitalization were analyzed using the national health system data. Hospital discharge registry ICD-10 codes were reviewed from 2008 to 2015. Results: The incidence of hip fractures increased in both women and men by 19.4% and 14.2%, respectively. The female to male fracture ratio was 2.46. Mean postoperative hospitalization decreased from 13.6 to 11.2 days. The one-year mortality ranged between 30.45% to 32.8% for men and 26.2% to 28% for women. Of note, women aged 80–89 had the highest one-year mortality, 50.7%–55.4% after femoral neck fracture and 53%–58.5% after a pertrochanteric fracture. Conclusions: Hip fractures in Poland are increasingly more prevalent in the aging population. The unfavorable trends observed in this study indicate higher annual mortality after hip fracture, compared with other European countries.

The aim of this study was to evaluate a modified method of calculating the 99mTc/90Y tumor-to-normal-liver uptake ratio (mT/N) based on SPECT/CT imaging, for use in predicting the overall response of colorectal liver tumors after radioembolization. A modified phantom-based method of tumor-to-normal-liver ratio calculation was proposed and assessed. In contrast to the traditional method based on data gathered from the whole tumor, gamma counts are collected only from a 2D region of interest delineated in the SPECT/CT section with the longest tumor diameter (as specified in RECIST 1.1). The modified tumor-to-normal-liver ratio (mT/N1) and 90Y predicted tumor absorbed dose (PAD) were obtained based on 99mTc-MAA SPECT/CT, and similarly the modified tumor-to-normal-liver ratio (mT/N2) and 90Y actual tumor absorbed dose (AAD) were calculated after 90Y-SPECT/CT. Tumor response was assessed on follow-up CTs. Using the newly proposed method, a total of 103 liver colorectal metastases in 21 patients who underwent radioembolization (between June 2009 and October 2015) were evaluated in pre-treatment CT scans and 99mTc-MAA-SPECT/CT scans and compared with post-treatment 90Y-SPECT/CT scans and follow-up CT scans. The results showed that the mT/N1 ratio (p = 0.012), PAD (p < 0.001) and AAD (p < 0.001) were predictors of tumor response after radioembolization. The time to progression was significantly lengthened for tumors with mT/N1 higher than 1.7 or PAD higher than 70 Gy. The risk of progression for tumors with mT/N1 lower than 1.7 or PAD below 70 Gy was significantly higher. The mT/N2 ratio had no significant correlation with treatment results.ConclusionThe mT/N1 ratio, PAD, and AAD can be used as predictors of tumor response to SIRT treatment, and SPECT/CT imaging can be used for dosimetric assessment of radioembolization.

Our results can help harmonize standards for MT in Poland according to international guidelines.

Hypotension, anemia requiring blood transfusion, and administration of CM exceeding 150 ml poses higher risk of AKI development, which leads to longer hospital stay and need of dialysis. The Mehran score may be used as predictor of AKI occurrence. Up to one third of the kidney was embolized with no AKI linked to the procedure. The concern of AKI occurrence should not be a cause of delay of endovascular treatment.

Introduction There are mixed reports on the incidence of intracranial haemorrhage in patients with dural arteriovenous fistulas. We assessed new proposed risk factors (i.a. number of outflows and outflow diameter) of intracerebral haemorrhage due to intracranial dural arteriovenous fistula and presented our personal experience in endovascular treatment of dural arteriovenous fistulas. Material and methods The patient database from January 2006 and December 2016 was reviewed, and 25 patients with 28 dural arteriovenous fistulas were identified. Results 50% of patients presented with intracerebral haemorrhage. Multiple dural fistulas occurred in 12% of patients. Spearman’s rank correlation coefficient revealed that there was a strong association between Cognard classification type and time needed to treat ( r = 0.59, p < 0.05), as well as the volume of contrast used ( r = 0.77, p < 0.05). Infratentorial ( r = 0.53, p < 0.05) and right-sided ( r = 0.66, p < 0.05) localisation were more challenging to treat. Bleeding was associated with poorer clinical outcome ( r = 0.48, p < 0.05). No significant differences were found between the non-haemorrhagic group and the haemorrhagic group regarding the number of outflows ( p = 0.459) and largest outflow diameter ( p = 0.298). Clinical evaluation at follow-up was as follows: 56% of patients were asymptomatic, 24% had non-significant disability, maintaining independency, 16% had moderate disability, and 8% died – one in the course of intracerebral haemorrhage and one due to other sustained injuries. There were no reported embolisation-related complications. Conclusions To conclude, regardless of presentation, both symptomatic and asymptomatic dural arteriovenous fistulas deserve clinical attention, structured evaluation, and follow-up. Type I fistulas were associated with haemorrhage in 1/3 of all cases. Overall our results indicate that the risk of haemorrhage and dire consequences is multifactorial.
