Proximal load transfer with a stemless uncemented femoral implant

Bone stock preservation is crucial when performing total hip replacement in young patients. The aim is to save good bone stock for a possible revision procedure. Furthermore, there is an increasing demand from young and active patients to receive a new joint which allows a normal or nearly normal life style. With this in mind, we began, in 1993, to develop a new femoral implant. The purpose of this ultra-short stem was a physiologic strain distribution on the proximal femur with a proximal load transfer from the implant to the femoral bone. Main features were an almost complete absence of the diaphyseal portion of the stem, a well defined lateral flare with load transfer on the lateral column of the femur, and a very high femoral neck cut. These innovations resulted in a conservative implant on both the bone stock and the soft tissues. This implant, in the first years, was recommended only for young and active patients. Over the last thirteen years, this project has undergone several modifications but the basic principles of the implant have remained the same. In the present review, we present the rationale, the surgical technique and the clinical and experimental results so far obtained with this implant.

Midwives as drivers of reproductive health commodity security in Kaduna State,Nigeria

Objectives: The significant improvement in the contraceptive prevalence rate in Kaduna State, Nigeria, from 8.4% in 2008 to 18.5% in 2013 is a notable achievement. This article analyses the role of midwives as drivers of reproductive health commodity security (RHCS) and their impact on contraceptive use in Kaduna State. Methods: The United Nations Population Fund (UNFPA) supported the bimonthly review resupply meetings facilitated by midwives at State and local government area (LGA) levels. The midwives deliver contraception to the LGAs for onward distribution to 6974 of the 25,000 health facilities across the country according to usage data from the previous 2 months. They also collect requisition, issue and resupply form data from the previous 2 months. Results: The active participation of midwives at the bimonthly meetings improved data timeliness by 23% and data completeness by 50% in 1 year. Only one health facility ran out of intrauterine devices and only 17% reported running out of female condoms. The total number of contraceptives issued increased from 31,866 in 2012 to 177,828 in 2013, resulting in a couple–year protection increase from 3408 in 2012 to 102,207 in 2013. Conclusions: Creation of increased demand and engagement of midwives in providing family planning services, especially long-acting contraceptive methods, coupled with the removal of cost to the user and the strengthening of the supply chain have been major factors in more than doubling the contraceptive prevalence rate.     

An assessment of the ability of tree guards to prevent browsing damage using captive swamp wallabies (Wallabia bicolor)

Tree guards made of wire, plastic mesh, plastic film and rigid plastic tubing were examined for their ability to prevent browsing by captive swamp wallabies. All plastic mesh guards guards were ineffective as were all guards less than 1.0 m high other than rigid plastic tubes. Wire mesh guards reduced browsing but installation was difficult and laborious.     

Household Social Characteristics of the Demand for Alcoholic Beverages Among Spanish Students

This paper studies how household social capital affects adolescents’ demand for alcoholic drinks. To that end, we focus on a theoretical framework that combines elements from the Model of Rational Addiction and the Model of Social Economics. For the empirical framework, we use a simultaneous Type II Tobit model, with data drawn from the Spanish National Survey on Drug Use in the School Population (2000, 2002, and 2004). The sample is comprised of 12,627 students aged 17 years old. Our results confirm that parents’ decisions about drinking are even more decisive in their children's behavior than socioeconomic variables, such as parents’ educative levels or working status. Parental responsibilities go beyond the endowment of health and educational goods and services; so, these results suggest the importance of designing family-drug use prevention programs. The study's limitations are noted.

股骨头髓芯减压骨形态发生蛋白填塞配合中药治疗早期股骨头坏死的临床研究

为探讨应用股骨头髓芯减压并骨形态发生蛋白植入配合自拟补肾活血生骨丸治疗早期股骨头缺血坏死的效果。采用髓芯减压术腔内填塞BMP，术后配合中药治疗早期股骨头坏死26例（治疗组），并与同期单纯应用髓芯减压术治疗的25例（西医组）进行对照研究。经2．5～4．5年，平均3．6年的随访，治疗组优良率为79，49％，对照组为62．86％。表明股骨头髓芯减压骨形态发生蛋白植入配合中药治疗早期股骨头坏死效果优于单纯应用髓芯减压治疗的效果。
