Introduction: Evidence regarding the development of pulmonary thromboembolism (PE) during hospitalization is unclear. We hypothesized that the incidence of PE could vary depending on clinical department and aimed to conduct a survey on the incidence of in-hospital PE.

Methods: We conducted a retrospective analysis using claims data of in-hospital patients in Japan. We collected background information regarding patients with and without PE occurrence during hospitalization. Further, we determined the incidence of PE and implemented prophylactic procedures in patients with and without surgery according to clinical department at admission. Finally, we examined the duration of hospital stay and in-hospital mortality rates in patients with and without PE.

Results: We found that 5007 (0.107%, 20.61 per 1000 person-years) patients developed PE during hospitalization and differed by clinical department at admission. Moreover, 2272 (0.095%, 19.3 per 1000 person-years) and 2735 (0.119%, 21.8 per 1000 person-years) patients with and without surgery, respectively, developed PE during hospitalization (P < 0.001). Further, 33.8% of inpatients underwent prophylactic procedures for PE; however, the implementation rate differed between patients with and without surgery (59.2% vs. 7.3%, P < 0.001). The median duration of hospital stay in patients with and without PE was 31.0 and 11.0 days, and the in-hospital mortality rates in patients with and without PE were 11.0% and 3.5%, respectively (P < 0.001).

Discussion: The incidence of in-hospital PE differed according to patient characteristics, clinical departments, and presence/absence of surgery. The onset of PE during hospitalization leads to prolonged hospital stay and in-hospital death.

Conclusion: It is important to conduct a proper risk assessment on admission as well as to implement proper prophylactic procedures to prevent the development of PE during hospitalization.

Outcome measures in muscular dystrophy rehabilitation: an ICF content comparison approach to the most commonly used MD scales.

Introduction: Functioning is the reason to be of rehabilitation as it is essential to the lives of people who suffer from a disease. The International Classification of Functioning, Disability and Health (ICF) can help in designing a functioning profile of a patient, identifying needs for rehabilitation plans and measuring the results of an intervention.

Objective: To identify the outcome measurement instruments reported in clinical studies in muscular dystrophies (MDs) and provide an ICF content analysis.

Background: Postoperative patients' risk for developing venous thromboembolism (VTE) can be predicted using the adapted Caprini risk assessment model which informs administration of postoperative VTE prophylaxis. The study aimed to assess the appropriateness of postoperative VTE prophylaxis of patients according to the adapted Caprini scores and investigate whether a patient's HIV status influenced postoperative VTE prophylaxis administration.

Methods: This cohort study included patients who had elective or urgent surgery at a tertiary hospital, Bloemfontein.

Background: Endocrine hypertension is believed to be underestimated worldwide especially in the developing countries. There is a scarcity of publications on endocrine hypertension in sub-Saharan Africa. The aim of this study was to reflect the profile of patients with endocrine hypertension of adrenal/paraganglioma origin at Chris Hani Baragwanath Academic Hospital (CHBAH).

Exposure to heavy metals has been associated with affecting children's neurodevelopment, particularly increasing the risk of developing attention-deficit hyperactivity disorder (ADHD). The current exploratory study aims to investigate potential associations between presence of 15 different heavy metals in urine and ADHD. A total of 190 urine samples of participants from clinical and non-clinical population (non-ADHD = 66; ADHD = 124) aged between 6 and 15 years from Barcelona and Tarragona (Spain) were analysed.

Aim: To validate the prognostic value of the PAncreatic NeoAdjuvant MAssachusetts (PANAMA)-score and to determine its predictive ability for survival benefit derived from adjuvant treatment in patients after resection of pancreatic ductal adenocarcinoma (PDAC) following neoadjuvant FOLFIRINOX.

Background: The PANAMA-score was developed to guide prognostication in patients after neoadjuvant therapy and resection for PDAC. As this score focuses on the risk for residual disease after resection, it might also be able to select patients who benefit from adjuvant after neoadjuvant therapy.
