Prevention of recurrent hip fracture

Our objective was to describe the interventions aimed at preventing a recurrent hip fracture, and other injurious falls, which were provided during hospitalization for a first hip fracture and during the two following years. A secondary objective was to study some potential determinants of these preventive interventions. The design of the study was an observational, two-year follow-up of patients hospitalized for a first hip fracture at the University Hospital of Lausanne, Switzerland. The participants were 163 patients (median age 82 years, 83% women) hospitalized in 1991 for a first hip fracture, among 263 consecutively admitted patients (84 did not meet inclusion criteria, e.g., age >50, no cancer, no high energy trauma, and 16 refused to participate). Preventive interventions included: medical investigations performed during the first hospitalization and aimed at revealing modifiable pathologies that raise the risk of injurious falls; use of medications acting on the risk of falls and fractures; preventive recommendations given by medical staff; suppression of environmental hazards; and use of home assistance services. The information was obtained from a baseline questionnaire, the medical record filled during the index hospitalization, and an interview conducted 2 years after the fracture. Potential predictors of the use of preventive interventions were: age; gender; destination after discharge from hospital; comorbidity; cognitive functioning; and activities of daily living. Bi- and multivariate associations between the preventive interventions and the potential predictors were measured. Inhospital investigations to rule out medical pathologies raising the risk of fracture were performed in only 20 patients (12%). Drugs raising the risk of falls were reduced in only 17 patients (16%). Preventive procedures not requiring active collaboration by the patient (e.g., modifications of the environment) were applied in 68 patients (42%), and home assistance was provided to 67 patients (85% of the patients living at home). Bivariate analyses indicated that prevention was less often provided to patients in poor general conditions, but no ascertainment of this association was found in multivariate analyses. In conclusion, this study indicates that, in the study setting, measures aimed at preventing recurrent falls and injuries were rarely provided to patients hospitalized for a first hip fracture at the time of the study. Tertiary prevention could be improved if a comprehensive geriatric assessment were systematically provided to the elderly patient hospitalized for a first hip fracture, and passive preventive measures implemente

UN Peacekeeping at 75: Achievements, Challenges, and Prospects

This year marks the 75th anniversary of what the UN itself understands to be its first peacekeeping operation. It is therefore an appropriate time to reflect on the track record of UN peacekeeping in its efforts to try to maintain and realize peace and security. Moreover, this milestone invites us to ponder what lies ahead in the realm of peacekeeping. For this reason, this forum article brings together both academics and UN officials to assess the achievements and challenges of UN peacekeeping over the past 75 years. Through a dialogue among peacekeeping scholars and practitioners, we hope to identify current trends and developments in UN peacekeeping, as well as explore priorities for the future to improve the effectiveness of peacekeeping operations in terms of achieving their mandate objectives, such as maintaining peace, protecting civilians, promoting human rights, and facilitating reconciliation. This forum article is structured into six thematic sections, each shedding light on various aspects of UN peacekeeping: (1) foundational principles of UN peacekeeping - namely, consent, impartiality, and the (non-)use of force; (2) protection of civilians; (3) the primacy of politics; (4) early warning; (5) cooperation with regional organizations; and (6) the changing geopolitical landscape in which UN peacekeeping operates

Impact of a telephone triage service for non-critical emergencies in Switzerland: A cross-sectional study.

Telephone triage services (TTS) play an increasing role in the delivery of healthcare. The objective of this study was to characterize the adult users of a TTS for non-critical emergencies, describe the types of advice given and their subsequent observation, and assess the influence of TTS on the use of the healthcare system in a sanitary region of Switzerland. Data from a TTS based in the French part of Switzerland were analyzed. This service consists of a medical contact center for non-critical emergencies, with trained nurses available 24/7. A random selection of 2,034 adult calls was performed between July and December 2018. Research students contacted users 2 to 4 weeks after the initial call and assessed sociodemographic and clinical data, as well as the impact of the advice received on the use of the healthcare system. A sample of 412 users was included in the analyses. The average age was 49.0 (SD 20.4) years; 68.5% were women and 72.8% of Swiss origin. The two main recommendations provided by nurses were to consult the emergency department (ED) (44.6%, n = 184) and to contact a physician on duty (33.2%, n = 137). The majority of users followed the advice given by the nurses (substantial agreement [k = 0.79] with consulting the ED and perfect agreement [k = 0.87] with contacting a physician on duty). We calculated that calling the TTS could decrease the intention to visit the ED by 28.1%. TTS for non-critical emergencies have the potential to decrease the use of ED services

Real-World Data on Clinical Outcomes and Treatment Management of Advanced Melanoma Patients: Single-Center Study of a Tertiary Cancer Center in Switzerland

Background: Immune checkpoint inhibitors (ICIs) and BRAF/MEK inhibitors (BRAF/MEKi) have drastically changed the outcomes of advanced melanoma patients in both the resectable/adjuvant and unresectable/metastatic setting. In this follow-up analysis of real-world data, we aimed to investigate the clinical management and outcomes of advanced melanoma patients in a tertiary referral center in Switzerland approximately a decade after the introduction of ICIs and BRAF/MEKi into clinical use. Moreover, we aimed to compare the results with seminal phase 3 trials and to identify areas of high unmet clinical need. Methods: This single-center retrospective cohort study analyzed the melanoma registry of the University Hospital Zurich, a tertiary cancer center in Switzerland, and included patients treated in the resectable/adjuvant (n = 331) or unresectable/metastatic setting (n = 375). Results: In the resectable setting, adjuvant anti-PD1 or BRAF/MEKi showed a 3-year relapse-free survival (RFS) of 53% and 67.6%, respectively, and the overall median RFS was 50 months. Patients with lymph node plus in-transit metastases or with distant metastases prior to commencing adjuvant treatment had a significantly reduced overall survival (OS). In 10.9% of patients, the treatment was stopped due to toxicity, which did not affect RFS/OS, unless the duration of the treatment was p = 0.018). In the unresectable setting, first-line anti-PD1, anti-CTLA4/PD1 combination, or BRAF/MEKi showed a 5-year OS of 46.5%, 52.4%, and 49.2%, respectively. In a multivariate analysis, elevated LDH levels or the presence of brain metastases substantially shortened OS (HR > 1.78, p p = 0.15). After a progression on first-line therapy, the median OS2 was reduced to below two years. Elevated LDH (HR 4.65, p p = 0.026), affected OS2. Conclusion: Our study offers real-world insights into the clinical management, treatment patterns, and outcomes of advanced melanoma patients in both the adjuvant and unresectable setting. Early relapses in patients undergoing adjuvant treatment pose a particular challenge but these patients are generally excluded from first-line trials. The approved first-line metastatic treatments are highly effective in the real-world setting with 5-year OS rates around 50%. However, outcomes remain poor for patients with brain metastases or who fail first-line treatment

Molecular analysis of the fibrinogen gene cluster in 16 patients with congenital afibrinogenemia: novel truncating mutations in the FGA and FGG genes

Congenital afibrinogenemia is an autosomal recessive disorder characterized by the complete absence of detectable fibrinogen. We previously identified the first causative mutations for this disease in a non-consanguineous Swiss family. These were homozygous deletions of approximately 11 kb of the fibrinogen alpha chain gene (FGA). Our subsequent study revealed that the majority of cases were attributable to truncating mutations in FGA, with the most common mutation affecting the donor splice site in FGA intron 4 (IVS4+1 G-->T). Here, we report 13 further unrelated patients with mutations in FGA, confirming the relative importance of this gene compared with FGG and FGB in the molecular aetiology of afibrinogenemia. Three other patients were homozygous for mutations in FGG. Eight novel mutations were identified: five in FGA and three in FGG. Sufficient mutation data is now available to permit an effective strategy for the genetic diagnosis of congenital afibrinogenemia
