RESUMO
PURPOSE: Knowledge of clinical pharmacotherapy is essential for all who prescribe medication. The aims of this study were to investigate differences in the pharmacotherapy and polypharmacy knowledge of medical and surgical residents and consultants and whether this knowledge can be improved by following an online course. METHODS: Design: A before-and-after-measurement. SETTING: An online course available for Dutch residents and consultants working in hospitals. STUDY POPULATION: Dutch residents and consultants from different disciplines who voluntarily followed an online course on geriatric care. INTERVENTION: An online 6-week course on geriatric care, with 1 week dedicated to clinical pharmacotherapy and polypharmacy. Variables, such as medical vs surgical specialty, consultant vs resident, age, and sex, that could predict the level of knowledge. The effects of the online course were studied using repeated measures ANOVA. The study was approved by the National Ethics Review Board of Medical Education (NERB dossier number 996). RESULTS: A total of 394 residents and 270 consultants, 220 from surgical and 444 from medical specialties, completed the online course in 2016 and 2017. Residents had higher test scores than consultants for pharmacotherapy (73% vs 70%, p < 0.02) and polypharmacy (75% vs 72%, p < 0.02). The learning effect did not differ. Medical residents/consultants had a better knowledge of pharmacotherapy (74% vs 68%, p < 0.001) and polypharmacy (77% vs 66%, p < 0.001) than surgical residents/consultants, but the learning effect was the same. CONCLUSIONS: Residents and consultants had a similar learning curve for acquiring knowledge, but residents outperformed consultants on all measures. In addition, surgical and medical residents/consultants had similar learning curves, but medical residents/consultants had higher test scores on all measures.

Emergency physicians (EPs) often regard care for older adults as complex, while they lack sufficient geriatric skills. This study evaluates the effect of a geriatric education program on EPs' geriatric knowledge, attitude and medical practice when treating older adults. A mixed-methods study was performed on EPs from two Dutch hospitals. Effects were measured by pre-post tests of EPs' (n = 21) knowledge of geriatric syndromes and attitudes toward older adults, and by a retrospective pre-post analysis of 100 records of patients aged 70 years or more. Six EPs were purposively sampled and interviewed after completion of the education program. The program significantly improved EPs' geriatric knowledge. EPs indicated that the program improved their ability and attentiveness to recognize frailty and geriatric syndromes. The program also significantly improved EPs' attention for the older patient's social history and circumstances (P = 0.04) but did not have a significant effect on medical decision making. EPs valued especially the case-based teaching and indicated that the interactive setting helped them to better understand and retain knowledge. Combined quantitative and qualitative data suggest that EPs benefit from geriatric emergency teaching. Future enhancement and evaluation of the geriatric education program is needed to confirm benefits to clinical practice and patient outcomes.

The evolution of major cannabinoids and terpenes during the growth of Cannabis sativa plants was studied. In this work, seven different plants were selected: three each from chemotypes I and III and one from chemotype II. Fifty clones of each mother plant were grown indoors under controlled conditions. Every week, three plants from each variety were cut and dried, and the leaves and flowers were analyzed separately. Eight major cannabinoids were analyzed via HPLC-DAD, and 28 terpenes were quantified using GC-FID and verified via GC-MS. The chemotypes of the plants, as defined by the tetrahydrocannabinolic acid/cannabidiolic acid (THCA/CBDA) ratio, were clear from the beginning and stable during growth. The concentrations of the major cannabinoids and terpenes were determined, and different patterns were found among the chemotypes. In particular, the plants from chemotypes II and III needed more time to reach peak production of THCA, CBDA, and monoterpenes. Differences in the cannabigerolic acid development among the different chemotypes and between monoterpene and sesquiterpene evolution patterns were also observed. Plants of different chemotypes were clearly differentiated by their terpene content, and characteristic terpenes of each chemotype were identified.

In the last decade perforator flaps have been used increasingly for different indications. Many regions may serve as donor site. In this respect the posterior thigh region (PTR) has been neglected as a potential donor site for many years. The purpose of this study was to provide complete mapping of perforators supplying the posterior thigh region. Twelve fresh cadaver thighs were prepared injecting diluted acrylic paint into the iliac artery. Thereafter the posterior thighs were dissected from medial to lateral, distinguishing the perforators at the level of the superficial fascia. The perforators were localized and origin, source, length and diameter of the perforators were documented. Analysis occurred using ANOVA and the two proportion Z test. The distribution of musculocutaneous and septocutaneous perforators was respectively 69.1% and 30.9% (P = 0.002). The PTR was divided in thirds. Most perforators (53.2%) were found in de middle third of the PTR. The deep femoral artery (DFA) was the main origin of perforators (61.7%), followed by the superficial femoral artery (SFA) (27.7%) and the popliteal artery (PA) (10.6%). The DFA perforators were the longest with a mean length of 13.7 ± 4,69 cm, the SFA perforators were 9.79 ± 3.76 cm and the PA perforators were 8.6 ± 3.37 cm. The PTR offers a sufficient number of suitable perforators to serve as an adequate donorsite for pedicled and free flaps.

Small bowel obstruction is one of the most frequent emergencies in general surgery, commonly affecting elderly patients. Morbidity and mortality from small bowel obstruction in elderly is high. Significant progress has been made in the diagnosis and management of bowel obstruction in recent years. But little is known whether this progress has benefitted outcomes in elderly patients, particularly those who are frail or have a malignancy as cause of the obstruction, and when considering quality of life and functioning as outcomes. In this review, we discuss the specific challenges and needs of elderly in diagnosis and treatment of small bowel obstruction. We address quality of life aspects and explore how the concept of geriatric assessment can be utilized to improve decision-making and outcomes for elderly patients with a small bowel obstruction.

INTRODUCTION: Surgical specialists and residents lack knowledge to adequately manage frail older patients. This study aims to evaluate the effects of an interactive online course regarding attitude, self-confidence and knowledge in perioperative management of the elderly patient. METHODS: The six-weeks course consisted of expert videos, literature readings, quizzes and forum discussions. Surgical consultants with geriatric expertise and geriatricians moderated online discussions and stimulated interaction. Knowledge, self-confidence and attitude of course participants were compared at the beginning and end of the course. RESULTS: 206 medical practitioners started the course. Knowledge scores improved significantly from 49% to 65% (pâ¯<â¯0.005). Participants felt more secure (pâ¯<â¯0.005) in the treatment of the older patient at the end of the course. A better attitude correlated with a higher total knowledge score in surgeons and surgical residents (pâ¯=â¯0.02). CONCLUSION: A six-week interactive online course on perioperative management of elderly patients increases relevant geriatric knowledge and improves self-confidence of residents and faculty.
