Preoperative Management of Endocrine,Hormonal, and Urologic Medications: Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement

Perioperative medical management is challenging due to the rising complexity of patients presenting for surgical procedures. A key part of preoperative optimization is appropriate management of long-term medications, yet guidelines and consensus statements for perioperative medication management are lacking. Available resources utilize the recommendations derived from individual studies and do not include a multidisciplinary focus or formal consensus. The Society for Perioperative Assessment and Quality Improvement (SPAQI) identified a lack of authoritative clinical guidance as an opportunity to utilize its multidisciplinary membership to improve evidence-based perioperative care. SPAQI seeks to provide guidance on perioperative medication management that synthesizes available literature with expert consensus. The aim of this Consensus Statement is to provide practical guidance on the preoperative management of endocrine, hormonal, and urologic medications. A panel of experts with anesthesiology, perioperative medicine, hospital medicine, general internal medicine, and medical specialty experience was drawn together and identified the common medications in each of these categories. The authors then utilized a modified Delphi approach to critically review the literature and generate consensus recommendations.     

‘Out of house’ virtual surgical planning for mandible reconstruction after cancer resection: is it oncologically safe?

The purpose of this study was to investigate whether the time delay between ‘out of house’ proprietary virtual surgical planning (OH-VSP) of the mandibular resection for oral cancer and the actual surgery results in compromised margins and oncological disadvantage for the patient. Outcomes of patients who had OH-VSP of their mandibular resection and reconstruction were compared with those of patients who had the same surgery using a conventional non-VSP approach. The groups were similar in patient demographics, tumour stage and size, nodal status, and reconstruction complexity. VSP resulted in a significant reduction in operating time (P < 0.01). VSP did not affect bony (P = 0.49) or soft tissue (P = 0.22) margin status. In summary, VSP reduced the operating theatre time, and despite the time interval between bony resection planning and surgery, there was no compromise to the oncological safety of the operation.     

An Exploratory Cost-Effectiveness Analysis of the Connected Health Intervention to Improve Care for People with Dementia: A Simulation Analysis

Many people with dementia live in the community; thus, supporting informal caregivers is critical. The Connected Health intervention facilitates collection and sharing of patient data among informal caregivers and providers to identify emerging patient needs and support rapid decision-making. This study estimates the costs of care of dementia using time-driven activity based costing of an exemplar patient. Intervention costs and health utility values were derived from a feasibility study of the intervention. A Markov model produced estimates of the cost-effectiveness of the intervention under four scenarios: (1) a minimal effect of the intervention on disease progression; (2) moderate effects on disease progression, and minimal effects on quality of life (QOL) and cost; (3) minimal effects on disease progression and QOL, and a moderate effect on cost; (4) moderate effects on disease progression and cost, with minimal effects on QOL. Cost estimates of formal and informal care ranged from €3713 to €7614 per month. Intervention costs were €484 per month. Under scenarios 2, 3 and 4, the cost per quality-adjusted life year of the intervention falls below €45,000, the threshold below which the Health Information and Quality Authority in Ireland generally accepts interventions as cost-effective. The results suggest that the intervention would be cost-effective with limited reductions in rates of disease progression and cost of care, and with minimal improvements in quality of life. Future research should consider the specific experiences of intervention patients.     

口咽癌的综合治疗结果：单中心治疗经验

口咽鳞癌的临床处理仍存在争议，该文对口咽癌患者应用原发灶手术切除、颈淋巴清扫及术后行放疗的效果进行总结。对复合标准的211例患者进行回顾性研究。应用Kaplan—Meier曲线计算总生存率及无瘤生存率,应用单变量及多变量统计学分析研究疾病的临床特点与预后的关系。2年及5年的无瘤生存率分别为79．8％和68．8％．单因素分析表明，肿瘤切缘阳性是无瘤生存率重要也是唯一的预后因素。     

The Hall Technique; a randomized controlled clinical trial of a novel method of managing carious primary molars in general dental practice: acceptability of the technique and outcomes at 23 months

Background  

Scotland has high levels of untreated dental caries in primary teeth. The Hall Technique is a simplified method of managing carious primary molars using preformed metal crowns (PMCs) cemented with no local anaesthesia, caries removal or tooth preparation. This study compared the acceptability of the Hall Technique for children, their carers, and dentists, and clinical outcomes for the technique, with conventional restorations.     

Adipose derived stem cells and nerve regeneration

Injuries to peripheral nerves are common and cause life-changing problems for patients alongside high social and health care costs for society. Current clinical treatment of peripheral nerve injuries predominantly relies on sacrificing a section of nerve from elsewhere in the body to provide a graft at the injury site. Much work has been done to develop a bioengineered nerve graft, precluding sacrifice of a functional nerve. Stem cells are prime candidates as accelerators of regeneration in these nerve grafts. This review examines the potential of adipose-derived stem cells to improve nerve repair assisted by bioengineered nerve grafts.
