中医学发展有赖于对病证关系的再认识

提出就中医学辨证与辨病的关系,应该是方法与结果的关系.辨证必须以辨病为前提,证只有因病的存在才有自己的特殊性可言.而这时的病不能是传统意义上的以症状命名的"病",而必须是具有发展规律、表现出特定症状与相应阶段证候的"新"病.     

Development and pretesting of “Becoming Breastfeeding Friendly”: Empowering governments for global scaling up of breastfeeding programmes

Scaling up breastfeeding programmes has not been highly prioritized despite overwhelming evidence that breastfeeding benefits the health of mothers and children. Lack of evidence‐based tools for scaling up may deter countries from prioritizing breastfeeding. To fill this gap, Becoming Breastfeeding Friendly (BBF) was developed to guide countries in effectively scaling up programmes to protect, promote, and support breastfeeding. BBF includes an evidence‐based toolbox that consists of a BBF Index, case studies, and a 5‐meeting process. These three interrelated components enable countries to assess their breastfeeding scaling up environment, identify gaps, propose policy recommendations, develop a scaling up plan, and track progress. The toolbox was developed based on current evidence and expert guidance from a Technical Advisory Group, which was composed of global breastfeeding and metric experts with experience in the scaling up of health and nutrition programmes in low‐, middle‐, and high‐income countries. The BBF toolbox required a step‐by‐step iterative approach to describe and systematize each component, thus an operational manual was developed. The BBF toolbox and BBF operational manual underwent intensive pretesting in two countries, Ghana and Mexico, resulting in the modification of each component plus the operational manual. Pretesting continues in six additional countries demonstrating that BBF is a robust and dynamic multi‐sectoral process that, with relatively minor adaptations, can be successfully implemented in countries across world regions.     

The reproducibility issue and preclinical academic drug discovery: educational and institutional initiatives fostering translation success

ABSTRACT

Introduction: Drug discovery depends critically upon published results from the academy. The reproducibility of preclinical research findings reported by academia in the peer-reviewed literature has been called into question, seriously jeopardizing the value of academic science for inventing therapeutics.

Areas covered: The corrosive effects of the reproducibility issue on drug discovery are considered. Purported correctives imposed upon academia from the outside deal mainly with expunging fraudulent literature and imposing punitive sanctions on the responsible authors. The salutary influence of such post facto actions on the reproducibility of discovery-relevant preclinical research data from academia appears limited. Rather, intentional doctoral-scientist education focused on data replicability and translationally-meaningful science and active participation of university entities charged with research innovation and asset commercialization toward ensuring data quality are advocated as key academic initiatives for addressing the reproducibility issue.

Expert opinion: A mindset shift on the part of both senior university faculty and the academy to take responsibility for the data reproducibility crisis and commit proactively to positive educational, incentivization, and risk- and reward-sharing practices will be fundamental for improving the value of published preclinical academic research to drug discovery.     

Dental age estimation of Omani children using Demirjian's method

Dental age plays a significant role in forensic dentistry, orthodontics and paediatric dentistry, as well as in general diagnosis and treatment planning. Different methods have been developed to determine dental age. One of the most commonly used methods is Demirjian’s method, which was developed in 1973 from research on a large number of French-Canadian children. It is based on the degree of tooth mineralisation by examining the radiological appearance of the lower mandibular left quadrant. The purpose of this study was to assess the dental age of Omani children using Demirjian's method and evaluate the applicability of the method in dental age estimation for Omani children. The sample consisted of 485 digital panoramic radiographs of children (264 males, 221 females) aged between 4.6?years and 16.5?years, and obtained from the records of the Military Dental Centre in Oman. The data were analysed using SPSS. Paired t-tests, intraclass correlation coefficients (ICC) and difference-against-mean plots were used to compare the dental age calculated by Demirjian's method with chronological age. A single examiner scored the radiographs, and intra-observer reliability was evaluated using Cronbach's alpha on data from rescoring one out of every 20 radiographs. For boys, the mean difference between chronological age and dental age for all age groups was 0.10 (95% CI ?0.03 to 0.24). For girls, the mean difference between chronological age and dental age for all age groups was 0.05 (95% CI ?0.11 to 0.22). Difference-against-mean plots showed no evidence of differential bias by age. For boys, the ICC was 0.896 (95% CI 0.869–0.917); for girls, it was 0.886 (95% CI 0.854–0.911). Difference-against-mean plots for boys (Fig. 1) and girls (Fig. 2) showed some evidence of differential bias by age. In conclusion, the extent of the observed differences was sufficient for doubt to be cast upon the utility of Demirjian’s method for Oman, particularly when it is considered that the method’s most likely application would be in age determination for minors in the workforce.     

Treatment development: Can we find a better way?

The present paper argues that traditional approaches to treatment development, including a technological approach, a stage model, and existing inductive approaches such as functional analysis are inadequate in various ways. Treatment developing needs to focus more on theoretical development, practicality, and the fit with clients and practitioners. We argue that progress requires greater philosophical clarity, and steps to ensure a connection between philosophy of science assumptions and an analytic agenda which fits naturally with applied psychology. Theoretical progress requires distinguishing between clinical and basic models and harmonizing their relationship, and more focus on the manipulable context of action. Applied psychology needs to join in a common cause with basic psychology in domains of mutual interest, and develop basic analyses and mid-level terms that can be both scientifically progressive and clinically useful. Issues of practicality, capacity for dissemination, and public health impact need to be considered at the beginning and throughout treatment development. Issues of effectiveness, change processes, mediation, moderation, training, active components, and similar issues should be part of the evaluation system from the beginning. It is time to create a more coherent approach to treatment innovation.
