Abstract Purpose To evaluate the clinical outcomes of patients with a minimum 2-year follow-up following contemporary patellofemoral inlay arthroplasty (PFIA) and to identify potential risk factors for failure in a multi-center study. Methods All patients who underwent implantation of PFIA between 09/2009 and 11/2016 at 11 specialized orthopedic referral centers were enrolled in the study and were evaluated retrospectively at a minimum 2-year follow-up. Clinical outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Tegner Scale, the visual analogue scale (VAS) for pain, and subjective patient satisfaction. Pre- and perioperative risk factors were compared among failures and non-failures to determine potential risk factors. Results A total of 263 patients (85% follow-up rate) could be enrolled. The mean age at the time of index surgery was 49 ± 12 years with a mean postoperative follow-up of 45 ± 18 months. The overall failure rate was 11% (28 patients), of which 18% (5 patients) were patients with patella resurfacing at index surgery and 82% (23 patients) were patients without initial patella resurfacing. At final follow-up, 93% of the patients who did not fail were satisfied with the procedure with a mean transformed WOMAC Score of 84.5 ± 14.5 points, a mean KOOS Score of 73.3 ± 17.1 points, a mean Tegner Score of 3.4 ± 1.4 points and a mean VAS pain of 2.4 ± 2.0 points. An increased BMI was significantly correlated with a worse postoperative outcome. Concomitant procedures addressing patellofemoral instability or malalignment, the lack of patellofemoral resurfacing at the index surgery and a high BMI were significantly correlated with failure in our patient cohort. Conclusion Patellofemoral inlay arthroplasty shows high patient satisfaction with good functional outcomes at short-term follow-up and thus can be considered a viable treatment option in young patients suffering from isolated patellofemoral arthritis. Patellar resurfacing at index surgery is recommended to decrease the risk of failure. Level of evidence Retrospective case series, Level IV.

Research on anxiety in oldest-old individuals is scarce. Specifically, incidence studies based on large community samples are lacking. The objective of this study is to assess age- and gender-specific incidence rates in a large sample of oldest-old individuals and to identify potential risk factors. The study included data from N = 702 adults aged 81 to 97 years. Anxiety symptoms were identified using the short form of the Geriatric Anxiety Inventory (GAI-SF). Associations of potential risk factors with anxiety incidence were analyzed using Cox proportional hazard models. Out of the N = 702 older adults, N = 77 individuals developed anxiety symptoms during the follow-up period. The incidence rate was 51.3 (95% CI: 41.2–64.1) per 1000 person-years in the overall sample, compared to 58.5 (95% CI: 43.2–72.4) in women and 37.3 (95% CI: 23.6–58.3) in men. Multivariable analysis showed an association of subjective memory complaints (HR: 2.03, 95% CI: 1.16–3.57) and depressive symptoms (HR: 3.20, 95% CI: 1.46–7.01) with incident anxiety in the follow-up. Incident anxiety is highly common in late life. Depressive symptoms and subjective memory complaints are major risk factors of new episodes. Incident anxiety appears to be a response to subjective memory complaints independent of depressive symptoms.

Background and Purpose: In-hospital cardiac arrest (IHCA) has high mortality rate, which needs more research. This multi-center study aims to evaluate potential risk factors for mortality in patients after IHCA.Methods: Data for this study retrospectively enrolled IHCA patients from 14 regional hospitals, two district hospitals, and five medical centers between 2013 June and 2018 December. The study enrolled 5,306 patients and there were 2,871 patients in subgroup of intensive care unit (ICU) and emergency room (ER), and 1,894 patients in subgroup of general wards.Results: As for overall IHCA patients, odds ratio (OR) for mortality was higher in older patients (OR = 1.69; 95% CI:1.33–2.14), those treated with ventilator (OR = 1.79; 95% CI:1.36–2.38) and vasoactive agents (OR = 1.88; 95% CI:1.45–2.46). Whereas, better survival was reported in IHCA patients with initial rhythm as ventricular tachycardia (OR = 0.32; 95% CI: 0.21–0.50) and ventricular fibrillation (OR = 0.26; 95% CI: 0.16–0.42). With regard to ICU and ER subgroup, there was no mortality difference among different nursing shifts, whereas for patients in general wards, overnight shift (OR = 1.83; 95% CI: 1.07–3.11) leads to poor outcome.Conclusion: For IHCA patients, old age, receiving ventilator support and vasoactive agents reported poor survival. Overnight shift had poor survival for IHCA patients in general wards, despite no significance in overall and ICU/ER subgroups.

Purpose To analyze the appearance of primary and recurrent aggressive fibromatosis (AF) on MRI with a focus on configuration and to determine potential risk factors for recurrences detected on MRI follow-up scans. Methods From 79 consecutive patients with histologically proven diagnosis of AF, 39 patients underwent a minimum of four 1.5 T MRI follow-up scans after resection of primary AF between 2008 and 2018. The primary and recurrent tumors were radiographically examined for configuration, limitation and extent on MRI. Epidemiological data and loco-regional subcutaneous edema, muscle edema and post-operative seroma were included. Results The mean age of the patients was 39 ± 2.6 years. Primary and recurrent AF most often occurred in the thigh. The main appearance of primary AF was significantly most often fascicular (p = 0.001–0.01) with heterogeneous and marked contrast enhancement. 21 % (n = 8) of the patients developed recurrences of AF. A fascicular configuration with homogeneous/heterogeneous contrast enhancement was the main appearance of recurrent AF, but recurrent AF appeared nodular, polycyclic, ovoid or streaky/flat as well. Recurrent AF significantly most often occurred within the first 9 months after primary tumor resection (p = 0.009), especially in patients up to 25 years of age (RR = 6.1; 95 % CI: 1.8–20.9; p = 0.004). The cases of recurrent AF were altogether significantly smaller than the primary tumors (p = 0.001). Post-treatment subcutaneous and muscle edema were present in 77 % and 56 %, respectively. Patients with muscle edema after primary tumor resection had a significantly higher risk for AF recurrences (relative risk ratio (RR) = 1.8; 95 % CI: 1.16–2.8; p = 0.0096). There was no significant difference detected in patients with complete or incomplete resection of the primary tumor. Conclusion Primary and recurrent aggressive fibromatosis has a mostly fascicular configuration, but may appear ovoid, nodular, streaky/flat or polycyclic as well. High risks for tumor recurrences are detected for patients up to 25 years of age, patients within the first 9 post-operative months and patients with muscle edema after primary tumor resection.

136 Background: Prostate cancer (Pca) has been found incidentally in radical cystoprostatectomy (RCP) specimens in 27-70%. We evaluated histopathological features and clinical outcome of patients with incidental Pca undergoing RCP for urothelial bladder cancer and identified potential risk factors for the presence of significant Pca, being defined as Gleason Score ≥7b, primary tumor ≥T2c or Pca volume ≥0.5cm3. Methods: A retrospective analysis of patients who underwent RCP between 01/2005-03/2015 was performed with regard to clinical data and pathohistological features. Whole mount serial sections of specimens were examined in the same urological and pathological institution. Pca grade, p-stage, cancer volume and surgical margins were recorded. Preoperative PSA values and follow-up were analysed. Results: We identified 71 patients with incidental Pca with a mean age of 71.7 years (47-84 years). 33/71 patients (46.5%) had significant Pca (28.2% ≥T2c, 4.2% GS ≥7b [+≥T2c], 14.1% cancer volume ≥0.5cm3[+≥T2c]). Other features were as follows: pT2a, n=36 (50.7%); pT2b, n=2 (2.8%); GS 6, n=50 (70.4%); GS 7a, n=18 (25,3%). All patients were R0 and N0 for Pca. Mean preoperative PSA level was 2.7ng/ml. None of the patients developed biochemical recurrence (median follow-up: 29.5 [1-124 months]). Patients with significant Pca were older than those with insignificant Pca (median age 71.2 years vs 70.1 years) and had higher preoperative PSA levels: 90% of patients with a PSA level of 4-10ng/ml had a ≥T2c Pca, while 81.5% of patients with PSA levels of 0-1ng/ml had a pT2a Pca. P-stages in patients with PSA values between 1-4ng/ml were found to be equally distributed between pT2a-pT2c. Conclusions: The occurence of incidental Pca is a common finding in patients undergoing RCP, with a considerable proportion having the characteristics of significant Pca. Potential risk factors for significant Pca are older age and PSA levels >4ng/ml. However, none of the patients experienced biochemical relapse or Pca-related death during the follow-up. In line with published data, incidental Pca does not impact on the oncological outcome of patients undergoing RCP. The prognosis is primarily determined by bladder cancer.

Nonostante i recenti progressi in tema di wound care, le ulcere varicose degli arti inferiori restano un problema frequente, con un alto tasso di recidiva. In questo lavoro abbiamo esaminato la storia clinica, la storia chirurgica e le patologie associate di 133 pazienti affetti da ulcera varicosa degli arti inferiori, di cui 56 da ulcera recidiva o plurirecidiva. L’analisi dei fattori di rischio potenziale per recidiva ha evidenziato come la presenza di varici recidive, una pregressa trombosi venosa profonda, problemi ortopedici, interventi ortopedici, l’obesità e un’età inferiore a 60 anni siano fattori di rischio potenziale per una recidiva dell’ulcera. La combinazione di uno più fattori di rischio assume significatività per la possibilità di una recidiva; si passa dal 22,7% in assenza di fattori di rischio al 33% per i pazienti che ne presentano due, fino al 57,5% in presenza di tre fattori di rischio e all’81,3% per quattro o più. L’ulcera varicosa richiede un follow-up stretto del paziente e una terapia elastocompressiva continua, che deve vedere una stretta collaborazione del paziente e un’attenzione specifica ai fattori di rischio. Despite recent advances in wound care, varicose ulcers of lower limbs remain frequent and display a high rate of recurrence. In this paper, we examined the clinical, surgical histories and associated diseases of 133 patients with venous ulcers of the lower limbs, which were recurrent in 56 cases. The analysis of potential risk factors for recurrence showed that the presence of recurrent varicose veins, a previous deep venous thrombosis, orthopedic problems, previous orthopedic procedures, obesity and age lower than 60 are potential risk factors for ulcer recurrence. Furthermore, the association of one or more risk factors increased the likelihood of relapse, from 22.7% with no risk factors to 33% with 2 risk factors, up to 57.5% with 3 risk factors, and up to 81.3% with 4 risk factors or more. Venous ulcers require close follow-up and continuous elastic compression, close collaboration by the patient and specific focus on risk factors.

SUMMARYTwo independent studies were conducted to describe symptoms and potential risk factors associated withBlastocystisinfection. Isolates were subtyped by molecular analysis. In the NORMAT study (126 individuals randomly sampled from the general population) 24 (19%) were positive forBlastocystis.Blastocystiswas associated with irritable bowel syndrome (P=0·04), contact with pigs (P<0·01) and poultry (P=0·03). In the Follow-up (FU) study (follow-up of 92Blastocystis-positive patients), reports on bloating were associated with subtype (ST) 2 (P<0·01), and blood in stool to mixed subtype infection (P=0·06). ST1 was more common in FU individuals (32%) than in NORMAT individuals (8%), whereas single subtype infections due to ST3 or ST4 were seen in 63% of the NORMAT cases and 28% of the FU cases. Only FU individuals hosted ST7, and ST6/7 infections due to ST7 or ST9 were characterized by multiple intestinal symptoms. The data indicate subtype-dependent differences in the clinical significance ofBlastocystis.
