The impact of advanced patient age in liver transplantation: a European Liver Transplant Registry propensity-score matching study

BackgroundThe futility of liver transplantation in elderly recipients remains under debate in the HCV eradication era.MethodsThe aim was to assess the effect of older age on outcome after liver transplantation. We used the ELTR to study the relationship between recipient age and post-transplant outcome. Young and elderly recipients were compared using a PSM method.ResultsA total of 10,172 cases were analysed. Recipient age >65 years was identified as an independent risk factor associated with reduced patient survival (HR:1.42 95%CI:1.23–1.65,p < 0.001). After PSM, 2124 patients were matched, and the same association was found between elderly recipients and patient survival and graft survival (p < 0.001). As hepatocellular carcinoma and alcoholic cirrhosis were independent prognostic factors for patient and graft survival a propensity score-matching was performed for each. Patient and graft survival were significantly worse (p < 0.05) in the alcoholic cirrhosis elderly group. However, patient and graft survival in the hepatocellular carcinoma cohort were similar (p > 0.05) between groups.ConclusionLiver transplantation is an acceptable and safe curative option for elderly transplant candidates, with worse long-term outcomes compare to young candidates. The underlying liver disease for liver transplantation has a significant impact on the selection of elderly patients.     

The association between physical activity time and neuropathy in longstanding type 1 diabetes: A cross-sectional analysis of the Canadian study of longevity in type 1 diabetes

AimPhysical activity (PA) is recommended to improve glycemic control in T1D; however, the effect of PA on distal symmetric polyneuropathy (DSPN) and cardiac autonomic function in longstanding T1D is unknown.MethodsData from 75 participants were collected as part of the Canadian Study of Longevity in T1D. Participants completed a physical exam, medical history, extensive complications phenotyping and reported their daily PA from the preceding 12-months. Pearson and Spearman correlations were used to assess PA time and complications variables. Linear regression was used to test associations between PA time, neurological and electrophysiological measures. Univariable regression was used to indicate the change in the given independent variables associated with a 30-min increase in PA per week.ResultsParticipants were 66 ± 8 years old with diabetes duration of 54 [52,58] years, HbA_1c was 7.3 ± 0.8, 65(89%) had DSPN. Weekly PA time was 156 ± 132 min, and 35(47%) reported ≧150 min/week. Participants with DSPN reported lower PA time compared to individuals without DSPN (141 ± 124 min/week vs. 258 ± 129 min/week; p = 0.015). PA time was associated with better cooling detection threshold (r = 0.24; p = 0.043), peroneal and sural amplitude (r = 0.36; p = 0.0017, r_s = 0.26; p = 0.024) and conduction velocity (r_s = 0.28; p = 0.015, r = 0.23; p = 0.050). Linear regression adjusting for age and HbA1c, showed that for each 30-min of PA there was a 0.09mv higher peroneal amplitude (p = 0.032) and 0.048 ms lower peroneal F-wave latency (p = 0.022).ConclusionIn longstanding T1D, PA time is associated with superior large nerve fibre function in the lower limbs and some better measures of small nerve fibre function.     

Evaluation of diagnostic algorithm and therapeutic interventions for intra-abdominal desmoid tumors

Desmoid-type fibromatosis (DF) is a distinctly rare condition, mostly of younger adults, characterized by the development of locally aggressive tumors of mesenchymal origin. Desmoid tumors (DT) arise either sporadically or in association with FAP (familial adenomatous polyposis), although certain risk factors have also been identified, including pregnancy and antecedent surgical trauma. They can emerge from any connective tissue including muscle, fascia and aponeurosis and are therefore classified, according to location, as intra-abdominal, of the abdominal wall and extra-abdominal. Despite the lack of metastasizing potential, the course can be unpredictable. Various mutations of APC and β-catenin genes, among others, play a catalytic role in the pathogenesis of this neoplastic entity. Surgery has lost its traditional role as first line treatment of the disease and several other treatment methods are being considered. Cytotoxic chemotherapy, non-cytotoxic systemic therapy and targeted therapy have been revealed as part of different treatment regimens. Recent progress regarding DT biology and molecular pathways has led to the development of promising novel biological agents. In any case, a multidisciplinary approach is required and is gradually employed, espe-cially in intra-abdominal DTs. In this review, we aim to present current knowledge on DF and summarize current treatment regimens as well as their effectiveness, with emphasis on the intraperitoneal type of DT.     

Gender Identity and Non-Binary Presentations in Adolescents Attending Two Specialized Services in Italy

BackgroundRecently, the variability and heterogeneity of gender presentations in transgender youths have gained significant attention worldwide. Alongside this, specialized gender services have reported an increase in referrals of youths reporting non-binary identities. In Italy, studies investigating gender identity and expression in gender non-conforming youths are lacking, as are data regarding the non-binary population.AimThe present study aimed at dimensionally exploring how transgender and non-binary Italian adolescents identify and express their gender.OutcomesGender expression in trans binary youths and non-binary youths.MethodsThe Gender Diversity Questionnaire (GDQ; Twist & de Graaf, 2019) was used to investigate gender identity, gender fluidity, and gender expression in a sample of 125 adolescent patients from the Gender Identity Development Service (SAIFIP) in Rome and the Gender Incongruence Unit of the Careggi Hospital in Florence, between April 2019–June 2021.ResultsThe majority of participants (74.4%) identified as trans* binary and the remaining (25.6%) participants identified as non-binary. Trans binary participants reported a stable gender identity, whereas non-binary participants reported a more fluid gender identity across time and contexts. Almost all participants rated external appearance as important to their gender expression, yet trans binary participants attributed more importance to the body in this respect. Body discomfort and pubertal stage emerged as the most influential factors in participants’ experiences of gender. Participants who were assigned male at birth expressed significantly more desire for puberty blockers, whereas those who were assigned female at birth had a stronger desire to engage in breast/chest surgery. Non-binary participants sought different medical interventions relative to trans binary participants.Clinical ImplicationsThese results may be useful for clinicians working with transgender youths as they provide awareness regarding the features of young people who identify within and outside of binary constructions of gender.Strengths & LimitationsThis study provides useful data in gaining insight into understanding the variety of experiences and challenges of gender non-conforming youths. However as the sample was recruited from specialized services, it may not represent the entire gender non-conforming population in Italy.ConclusionThe results describe the range of gender identities and expressions among gender non-conforming youths attending gender specialized services in Italy, thereby improving our understanding of the variety of identities experienced and the specific medical needs of both trans binary and non-binary adolescents.Mirabella M, Piras I, Fortunato A, et al.

Premature Ventricular Contractions (PVCs): A Narrative Review

Premature ventricular complexes/contractions (PVCs) are relatively common, occurring in 3%-20% of the general population, and are often found during work-up of palpitations or incidentally on routine electrocardiographic testing. They are usually considered benign but can be a sign of underlying cardiac disease and cause significantly impairing symptoms. While often thought of as a problem for the cardiologist, it is not uncommon for PVCs to be identified initially in a primary care or inpatient general medicine setting. This paper will review etiologies, epidemiology, evaluation, and management of PVCs for the internist.     

Care of Seniors with Breast Cancer – Treatment Received and Refining Decision Making

AimsTreatment decisions for older patients with breast cancer are complex and evidence is largely extrapolated from younger populations. Frailty and comorbidity need to be considered. We studied the baseline characteristics and treatment decisions in older patients in Christchurch with breast cancer and assessed survival outcomes and prognostic/discriminatory performance of several tools.Materials and methodsWe searched the Canterbury Breast Cancer Registry and identified patients aged 70 years or older at diagnosis with invasive, non-metastatic breast cancer between 1 June 2009 and 30 June 2015. We retrieved demographics, treatment and outcome information. Overall survival and breast cancer-specific survival were estimated. Tools analysing performance status and comorbidity were assessed for their prognostic and discriminatory power.ResultsIn total, 440 patients were identified. Primary surgery was carried out for 362 patients (82.3%): breast-conserving surgery in 114 (of whom 88.6% received radiation therapy); mastectomy in 248 (of whom 24.6% received radiation). Hormone therapy was given for 265 (71.1%) patients with oestrogen receptor-positive cancers. Two hundred and seventy-four (62.3%) patients received full standard treatment, which was associated with significantly improved 5-year survival and 5-year breast cancer-specific survival. The median estimated overall survival was 8.2 years (95% confidence interval 7.3–9.1 years). Of those who died, 71.3% of deaths were due to causes other than breast cancer or unknown causes. The comorbidity-adjusted life expectancy (CALE) showed partial prognostic accuracy. CALE, Charlson and Eastern Cooperative Oncology Group tools all showed discriminatory value.ConclusionIn this population-based series of older patients with breast cancer, showing high levels of primary and adjuvant treatment, patients were more likely to die of causes other than breast cancer. Performance status and comorbidity tools showed prognostic and discriminatory potential in this population supporting their use in treatment decision making. CALE showed the most potential to improve treatment decisions but requires validation in this population to improve prognostic accuracy.
