Objective To systematically review the evidence of the factors associated with self-rated health (SRH) and estimating the population attributable risk proportion (PARP) of interests in the elderly. Methods MEDLINE, EMbase, CBM, CNKI, VIP and WanFang Data were searched (from January 1960 to April 2011) for relevant literature. The combined effect on each factor associated with poor SRH was expressed as RR or OR (95%CI). The contribution of each factor to poor SRH in the elderly population was estimated with PARP. Meta-analysis was performed using RevMan 5.1 software. Results Twelve studies involving a total of 35 349 participants aged 60 or above were eligible in this systematic review. Ten studies were conducted in China and the rest two studies were from the USA and Brazil. Of them, only one was prospective cohort study and 11 studies were cross-sectional. The results of meta-analysis showed that the main factors associated with poor SRH in the elderly were dependency, diabetes and coronary heart disease with the corresponding OR and 95%CI as 12.10 (6.31, 23.20), 6.49 (3.21, 13.09) and 5.60 (1.07, 29.42), respectively. However, the top three factors contributing to poor SRH in the elderly population were coronary heart disease, having illness half one year ago and chronic disorders with the corresponding PARP as 53.91%, 52.56%, and 50.09%, respectively. It was not possible to perform sub-group analysis because of the limited quantity of studies on each factor associated with poor SRH. Conclusion Based on the current available evidence, it appears that chronic disorders are closely related to poor SRH and contribute most in the elderly population. However, due to the limitation of the included predominantly cross sectional studies which are not enough for causal argument, it is insufficient to determine the association of many factors with poor SRH. Further high-quality prospective cohort studies are needed.
ObjectiveTo investigate the treatment outcome of applying venous Flow-through flap in the replantation of severed finger with circularity soft tissue defect and vascular defect. MethodsBetween January 2010 and December 2012,11 cases (11 fingers) of severed finger with circularity soft tissue defect and vascular defect underwent replantation with venous Flow-through flaps.There were 8 males and 3 females,aged 18-42 years (mean,24.6 years).The cause of injury was squeeze injury in 6 cases,crush injury in 3 cases,and strangulation in 2 cases.Combined injuries included nerve defect in 3 cases (1.0,2.0,and 3.5 cm in length),and tendon defect in 2 cases (2.0 and 6.5 cm in length); cyclic skin and soft tissue defect was 3.0-4.5 cm in width,was 1/2-1 finger circumference in length,and was 2.0 cm×1.0 cm to 7.0 cm×4.5 cm in size.Six cases had complete circular defect (both finger artery and vein defects),and 5 cases had incomplete circular defect (only finger artery defect),and vascular defect was 1.0-4.5 cm in length.The time from injury to operation was 1.5-4.5 hours. ResultsVenous crisis occurred in 1 case at 2 days after operation,was cured after vein graft; flap edge necrosis was observed in 2 cases and was cured after dressing change and skin grafting respectively; flap edema and blister occurred in 2 cases and relieved spontaneously.The other 6 flaps and replanted fingers survived completely,with primary healing of incision.Ten cases were followed up 12-18 months (mean,15.5 months).Only a linear scar was seen at the donor sites,with no functional limitation.The flaps had similar color and texture to adjacent skin.The two-point discrimination was 6.5-13.0 mm (mean,8.6 mm).According to replanted finger function scoring system of Society of Hand Surgery of Chinese Medical Association,the results were excellent in 6 cases,good in 3 cases,and poor in 1 case at last follow-up,and the excellent and good rate was 90%. ConclusionVenous Flow-through flap can repair both vascular defect and soft tissue defect,so it has good outcome in increasing the survival rate of replanted finger for severed finger replantation with circularity soft tissue defect and vascular defect.
ObjectiveTo investigate the effectiveness of the island flaps based on the superficial palmar branch of the radial artery (SPBRA) to repair the thumb wound. MethodsBetween February 2012 and November 2013, 8 cases of thumb defects and bilateral artery defect were treated. There were 5 males and 3 females with an average age of 30.5 years (range, 19-51 years). The injury was caused by crush (4 cases), avulsion (3 cases), and twist (1 case). The injury located at the metacarpophalangeal joints in 3 cases, at the proximal palmar side in 2 cases, and at the interphalangeal joints in 3 cases. The defect size ranged from 3.5 cm×1.5 cm to 6.5 cm×2.0 cm. The digital artery defect was 2.5-8.5 cm (mean, 5.3 cm). The disease duration was 2.0-4.5 hours (mean, 3.2 hours). The reversed island flaps based on the SPBRA were designed, which size was 4.0 cm×2.0 cm to 7.5 cm×3.0 cm. The donor sites were closed directly. ResultsThe operation was successfully completed in 7 patients except 1 patient having vascular variation. All flaps survived completely. Wound and incision at the donor site healed by first intention. All patients were followed up 6-18 months (mean, 13 months). The flaps had similar color and texture to adjacent skin. Linear scar was seen at the donor site in 1 patient, with no functional limitation. According to the functional assessment criteria of upper limb by the Hand Surgery Branch of Chinese Medical Association, the results were excellent in 6 cases, good in 1 case, and fair in 1 case, with an excellent and good rate of 87.5%. ConclusionThe reversed island flap based on the SPBRA is an ideal flap for the thumb reconstruction because the advantages of reliable blood supply, easy dissection, less injury at donor site, and good repair results.
Objective To explore the effectiveness and operation method of the superficial branch of radial artery wrist crease flap for repair of ring tissue defect of the fingers. Methods Between June 2013 and March 2016, the superficial branch of radial artery wrist crease flap was used to repair ring finger tissue defect in 20 cases (21 fingers). There were 14 males and 6 females with an average age of 39.3 years (range, 12-61 years). The causes included machine injury in 9 cases, traffic accident injury in 6 cases, heat inury in 2 cases, and avulsed injury in 3 cases. The index finger was involved in 6 cases, middle finger in 6 cases, ring finger in 3 cases, and little finger in 6 cases. Combined injuries included exposure of bone, tendon, vessel, and nerve. The mean time of injury to operation was 3 hours (range, 0.5-5.5 hours) in 17 patients undergoing emergency operation, and was 8.5 days (range, 7-10 days) in 3 patients undergoing selective operation. The superficial palmar branch of the radial artery from the flap was used for bridging proper digital artery. The donor site was directly sutured in 19 cases and was repaired by skin grafting in 1 case. Results One case had blood blister at distal flap, which was cured after dressing change; the other flaps survived, and primary healing was obtained. Healing of incision at the donor site healed by first intention. The patients were followed up 6-24 months (mean, 12 months). The appearance, texture, and color of the flaps were satisfactory. The two-point discrimination ranged from 6 to 13 mm (mean, 9 mm) at 6 months after operation. According to the Chinese Medical Association Society of hand surgery of thumb and finger reconstruction function evaluation standard, the results were excellent in 13 cases, good in 4 cases, and fair in 3 cases; the excellent and good rate was 85%. Conclusion The superficial branch of radial artery wrist crease flap is an ideal choice for the repair of ring tissue defect of the fingers.
