The impact of brand image on customer satisfaction and brand loyalty: A systematic literature review.

This literature review examines the impact of brand image on customer satisfaction and brand loyalty in the context of foreign tourism. Following a review of relevant literature, 13,302 articles were found for this study, including the keywords "brand image (BI)", "customer satisfaction (CS)", and "brand loyalty (BL)". Considering the required inclusion and the quality of studies, we employed the rigorous PRISMA technique for comprehensive data synthesis and evaluated 79 articles for the final review. Our findings underscore the significant impact of brand image on shaping customer satisfaction and fostering brand loyalty within the foreign tourism sector. The study enriches the literature by incorporating self-congruity theory. In addition, factors like product quality, pricing, and advertising are identified as key determinants significantly influencing the proposed relationship.

Cobalt-related cardiomyopathy: A real concern! A review of published evidence.

BACKGROUND: Cobalt (Co) toxicity-related cardiomyopathy (CMP) in hip arthroplasty has recently been reported in the literature. The purpose of this review was to identify and assess available published evidence of CMP in hip arthroplasty patients and to derive recommendations for management. METHODS: We evaluated 23 cases reported till October 2018 and stratified into three categories, based on pre-existing risk factors for CMP, histological confirmation and evidence of systemic signs of Co toxicity. RESULTS: Co toxicity was considered to be the definite cause of CMP in 8 cases and probably contributory in 13 cases. Two cases were considered to have developed CMP secondary to pre-existing risk factors. Majority of the patients had good recovery of cardiac function after hip revision and cardiac management, but five cases deteriorated and died. CONCLUSION: Although Co-related CMP has been reported in a small number of cases of hip arthroplasty, a delay or missed diagnosis may lead to significant morbidity and mortality. Timely diagnosis, removal of causative implant and avoidance of metal articulations in revision for fractured ceramic implants may help in effective management.

Cobalt cardiomyopathy in hip arthroplasty.

BACKGROUND: Cobalt toxicity-related cardiomyopathy in hip arthroplasty has recently been reported in the literature. The purpose of this review is to identify and assess available published evidence of cardiomyopathy in hip arthroplasty patients and to derive recommendations for management. METHODS: We evaluated 23 cases reported until October 2018 and stratified them into 3 categories, based upon pre-existing risk factors for cardiomyopathy, histological confirmation, and evidence of systemic signs of cobalt toxicity. RESULTS: Cobalt toxicity was considered to be the definite cause of cardiomyopathy in 8 cases, and probably contributory in 13 cases. Two cases were considered to have developed cardiomyopathy secondary to pre-existing risk factors. Majority of the patients had a good recovery of cardiac function after hip revision and cardiac management, but 5 cases deteriorated and died. CONCLUSIONS: Although cobalt-related cardiomyopathy has been reported in a small number of cases of hip arthroplasty, a delay or missed diagnosis may lead to significant morbidity and mortality. Timely diagnosis, removal of causative implant, and avoidance of metal articulations in revision for fractured ceramic implants may help in an effective management.
