Brachytherapy boost improves biochemical recurrence rates in men with high-risk prostate cancer (HRPC). Few data are available on whether one isotope is superior to another. We compared the oncologic and morbidity outcomes of I-125 and Pd-103 in men with HRPC receiving brachytherapy.

Of 797 patients with HRPC, 190 (23.8%) received I-125 or 607 received Pd-103 with a median of 45Gy of external beam irradiation. Freedom from biochemical failure (FFBF), freedom from metastases (FFMs), cause-specific survival (CSS), and morbidity were compared for the two isotopes by the ANOVA and the χ
test with survival determined by the Kaplan-Meier method and Cox regression.

Men treated with I-125 had a higher stage (p < 0.001), biological equivalent dose (BED) (p < 0.001), and longer hormone therapy (neoadjuvant hormone therapy, p < 0.001), where men treated with Pd-103 had a higher Gleason score (GS, p < 0.001) and longer followup (median 8.3 vs. 5.3years, p < 0.001). Ten-year FFBF, FFM, and CSS for I-125 vs. Mavoglurant research buy Pd-103 were 77.5 vs. 80.2% (p= 0.897), 94.7 vs. 91.9% (p= 0.017), and 95.4 vs. 91.8% (p= 0.346), respectively. Men with T3 had superior CSS (94.1 vs. 79.5%, p= 0.001) with I-125. Significant covariates by Cox regression for FFBF were prostate specific antigen (PSA), the GS, and the BED (p < 0.001), for FFM PSA (p < 0.001) and GS (p= 0.029), and for CSS PSA, the GS (p < 0.001) and the BED (p= 0.022). Prostate cancer mortality was 7/62 (15.6%) for BED≤150Gy, 18/229 (7.9%) for BED >150-200Gy, and 20/470 (5.9%) for BED >200Gy (p= 0.029). Long-term morbidity was not different for the two isotopes.

Brachytherapy boost with I-125 and Pd-103 appears equally effective yielding 10-year CSS of over 90%. I-125 may have an advantage in T3 disease. Higher doses yield the most favorable survival.

Thoracolumbar fractures are a public health issue due to their severity and frequency. Management varies according to demographic, clinical and radiologic features, from non-operative treatment to extensive fusion. In the two last decades, improvements and new techniques have emerged, such as kyphoplasty and percutaneous approaches. The main goal of this study was to describe the management of thoracolumbar fractures in France in 2018.

The study hypothesis was that management of thoracolumbar fractures in France has progressed in recent decades.

The files of 407 adult patients operated on between January 1, 2015 and December 31, 2016 for T4-L5 thoracolumbar fracture in 6 French teaching hospitals were retrospectively reviewed, at a mean follow-up at 10.2±8.2 [1; 42] months. Demographic, surgical and postoperative radiological data were collected. p-values<0.05 on Student test were considered significant.

Five hundred and thirty-one fractures were analyzed (27% of patients presented more than one fr fusion, possibly due to lack of preoperative MRI in 79% of cases.

The occurrence of peri-acetabular metastasis (PAM) is a turning point in the progression of cancer because the disabling pain prevents the patient from walking or makes it difficult. Recent progress in controlling cancers that spread to the bone and controlling local bone destruction justify this national study. Since the data in France is incomplete or based on small studies, we analysed a multicentre retrospective cohort of patients with PAM who underwent total hip arthroplasty (THA) to evaluate 1) the clinical and radiological outcomes and 2) the factors impacting patient survival.

The clinical outcomes, complication rate and survivorship are comparable to that of recent published studies.

Ninety-one patients (27 men, 64 women) with a mean age of 62.7±10.5 years (extremes 38 and 88) with PAM secondary to breast cancer [42 patients (46%)] or lung cancer [20 patients (22%)] underwent THA. The metastasis was the first sign of cancer in 33 cases (36%). Concurrent visceral metastases were present in 30 pa used, the clinical outcomes in our study are like those in other published studies, as were the incidence of surgery-related complications and the survivorship. The recommended surgical technique is the implantation of an acetabular reinforcement cage, curettage with cement filling of osteolytic areas, dual mobility cup and cemented stem followed by radiation therapy. The role of THA versus interventional radiology procedures must still be determined.

In traumatic proximal brachial plexus lesions (i.e., C5/C6), reconstruction of the musculocutaneous, axillary and suprascapular nerves yields satisfactory short- and medium-term functional outcomes.

Early functional outcomes after nerve surgery will be maintained in the long-term.

A retrospective analysis was done using the medical records of 29 patients with C5/C6 palsy treated by nerve surgery. Active range of motion and strength at the elbow (i.e., flexion) and shoulder (i.e., flexion, abduction, external rotation with the elbow at the side of the body and with the arm 90° abducted ) were evaluated clinically using a goniometre and the British Medical Research Council grading scale, respectively.

At a mean follow-up of 46±15 months (25;76), the mean active elbow flexion was 126°±18° (90;150) and the mean strength was 3.8±0.5 (2;4). At the shoulder, mean active flexion, abduction, external rotation with the elbow at the side of the body and with the arm 90° abducted were 109°±39° (0;180), 99°±38° (0;180°), 12°±34° (-80;70) and 3°±21° (-40;50), while mean strength was 3.Mavoglurant research buy

Chemotherapy is a first-line treatment for many cancers; however, its use is hampered by a long list of side-effects. Gastrointestinal mucositis is a common and debilitating side-effect of anticancer therapy contributing to dose reductions, delays and cessation of treatment, greatly impacting clinical outcomes. The underlying pathophysiology of gastrointestinal mucositis is complex and likely involves several overlapping inflammatory, secretory and neural mechanisms, yet research investigating the role of innervation in gastrointestinal mucositis is scarce. This review provides an overview of the current literature surrounding chemotherapy-induced enteric neurotoxicity and discusses its implications on gastrointestinal mucositis.

Damage to the intrinsic nervous system of the gastrointestinal tract, the enteric nervous system (ENS), occurs following chemotherapeutic administration, leading to altered gastrointestinal functions. Selleckchem Tacrolimus Chemotherapeutic drugs have various mechanisms of actions on the ENS. Oxidative stress, direct toxicity and inflammation have been identified as mechanisms involved in chemotherapy-induced ENS damage. Enteric neuroprotection has proven to be beneficial to reduce gastrointestinal dysfunction in animal models of oxaliplatin-induced enteric neuropathy.

Understanding of the ENS role in chemotherapy-induced mucositis requires further investigation and might lead to the development of more effective therapeutic interventions for prevention and treatment of chemotherapy-induced gastrointestinal side-effects.

Most contemporary metastatic renal-cell carcinoma patients receive first-line immunotherapy and tyrosine kinase inhibitor (TKI) combination or immunotherapy-immunotherapy combination, as first-line standards of care. However, second-line therapy choices are less well established. To address this void, we examined existing evidence supporting second and subsequent-line treatment options after immunotherapy-based combination therapy.

Evidence regarding efficacy of second-line therapy after immunotherapy-based combination is mainly retrospective, except for axitinib, which is the only TKI with prospective efficacy data in this setting. Cabozantinib demonstrated excellent second-line progression-free survival (PFS) that remained in third or later line use, albeit based on small numbers of observations. Moreover, pazopanib demonstrated excellent PFS, but showed wider variability in PFS rates. Sunitinib's PFS rates appeared lower than for axitinib, cabozantinib or pazopanib. Finally, inhibitors of the mammalian target of rapamycin pathway appeared to offer even lower efficacy than any TKI after immunotherapy-based therapy combinations.

All available contemporary evidence about TKI efficacy after immunotherapy-based therapy combinations is based on institutional studies. No major differences in efficacy for the examined TKIs after immunotherapy-based combination therapies were recorded. In general, these showed similar efficacy to their efficacy data recorded in first-line.

Informal caregivers of individuals affected by cancer undertake a range of activities and responsibilities throughout the course of the cancer care trajectory. This role is often undertaken alongside employment and other caring roles and can contribute to caregiver burden, which may be ameliorated through psychosocial intervention.

Fifteen new studies investigating the potential of psychosocial interventions for reducing caregiver burden were identified from the period January 2019 to February 2020. Studies were mostly quasi-experimental or randomised controlled trials (RCTs). Psychoeducation was the main intervention identified, though content varied, psychoeducation was associated with improvements in burden, quality of life (QoL) domains and psychological symptoms for caregivers. A small number of counselling/therapeutic interventions suggest that caregivers supporting patients with advanced cancer or cancers with high symptom burden may experience reduced psychological symptoms and QoL benefits. There was a paucity of evidence for other psychosocial interventions (e.g. mindfulness, acceptance and commitment therapy) and methodological quality was variable across all intervention types.

Psychosocial interventions may help to reduce burden for informal caregivers of individuals affected by cancer, though there remains a need for rigorously designed, multicentred RCTs and to examine the long-term impact of psychosocial interventions for caregivers.

The Oxford Knee Score (OKS) is a reliable, valid, and sensitive assessment tool for individuals undergoing a total knee arthroplasty (TKA). The published psychometric assessment of the Arabic version of the OKS (OKS-Ar) is limited to male patients and has not been assessed for responsiveness following TKA. The aim of this study was to assess the reliability, validity, and responsiveness of the OKS-Ar in an inclusive population of patients undergoing TKA.

One hundred Arabic-speaking patients awaiting TKA were assessed with the OKS-Ar, the Arabic version of the Knee injury and Osteoarthritis Outcome Score (KOOS-Ar), and a visual analogue scale for pain (VAS-P) in order to assess the correlation between the OKS-Ar and the KOOS-Ar and VAS-P and determine the construct validity. Repeat assessments were completed 7 to 10 days after the first assessment and 6 months after TKA.

Questionnaires were completed by 80 female and 20 male participants with a mean age of 62 ± 8 years. The test and retest median scores showed no significant difference from one another, with a strong Spearman correlation between the 2 measurements (rs = 0.Selleckchem Tacrolimus
