Reporting of core outcomes in gastric cancer surgery trials over the past 25 years (systematic review).

BACKGROUND: Gastric cancer, a leading cause of cancer-related mortality worldwide, has seen limited improvement in survival over the past 3 decades. Surgical resection is the cornerstone of curative management but the optimal approach remains unclear. Decision-making is hindered by inconsistent outcome reporting limiting data synthesis between trials. International consensus between healthcare professionals and patients has formed a core outcome set to be reported as a minimum. We appraised outcomes previously reported. METHODS: Evidence Based Medicine Reviews, MEDLINE, EMBASE and CINAHL were searched for randomised controlled trials (RCTs) and systematic reviews of RCTs during years 1995-2021. We searched trial registries for protocols of ongoing and future trials. RESULTS: Ninety-nine articles from 64 studies and 69 trial protocols were included. No study reported all core outcomes: average reported per trial was 4 (interquartile range: 2). 'Serious' adverse events were reported by 98%, completeness of tumour removal by 85% and surgery-related death by 74%. Outcomes important to patients were reported least: quality of life (22%) and nutritional effects (15%). Defining outcomes and time frames used was variable. CONCLUSIONS: Critically important outcomes are poorly reported in the literature and the status has not improved in future trials. Further work is required to improve uptake.

Nutritional status, diet quality and inflammatory markers in adolescents

To evaluate diet quality and relationship between Body Mass Index (BMI), diet quality and inflammatory markers in adolescents of public schools in São Luís-MA. Methodology: A cross-sectional study was conducted with 384 adolescents aged 17 and 18 years. The nutritional status was evaluated through the BMI. The quality of the diet was evaluated through the Revised Diet Quality Index (IQD-R). The inflammatory markers used were C-Reactive Ultrasensitive Protein (hs-CRP), IL-6 (Interleukin-6) and TNF-α (Tumor Necrosis Factor α). Multivariate analysis was performed using a decision tree using the CART (Classification and Regression Trees) algorithm to evaluate the relationship between BMI, diet quality and inflammatory markers. Results: The mean age was 17.3±0.5 years, predominance of females (56.5%) and eutrophic (69.3%). The mean IQD-R score was 55.3±12.7. Adolescents in the lowest tertile of IQD-R (T1) had a higher mean BMI (22.1±4.3 kg/m2 vs 21.5 ± 3.7kg/m2). Higher levels of IL-6 were observed in those located on the IQD-R T1 (1,345 mg/L vs 1,205 mg/L). In the same group (T1), adolescents who had higher IL-6 levels also had a higher mean BMI (23.6±5.1kg/m2 vs 20.8±3.0kg/m2). The adolescents in the largest tertiles of IQD-R (T2 and T3) and who had higher concentrations of IL-6 and CR-us had also a higher mean BMI (23.8±4.9kg/m2). Conclusions: The diet quality of adolescents studied needs modifications. BMI averages varied with diet quality and levels of IL-6 and hs-CRP(AU)

Avaliar a qualidade da dieta e a relação entre Índice de Massa Corporal (IMC), qualidade da dieta e marcadores inflamatórios em adolescentes de escolas públicas de São Luís-MA. Metodologia: Foi realizado um estudo transversal com 384 adolescentes de 17 e 18 anos. O estado nutricional foi avaliado por meio do IMC. A qualidade da dieta foi avaliada por meio do Índice de Qualidade da Dieta Revisado (IQD-R). Os marcadores inflamatórios utilizados foram Proteína C Reativa Ultrassensível (PCR-us), IL-6 (Interleucina-6) e TNF-α (Fator de Necrose Tumoral α). A análise multivariada foi realizada usando uma árvore de decisão usando o algoritmo CART (Classification and Regression Trees) para avaliar a relação entre IMC, qualidade da dieta e marcadores inflamatórios. Resultados: A média de idade foi de 17,3 ± 0,5 anos, predomínio do sexo feminino (56,5%) e eutrófico (69,3%). A pontuação média do IQD-R foi de 55,3 ± 12,7. Os adolescentes no tercil inferior do IQD-R (T1) tiveram uma média de IMC mais alta (22,1 ± 4,3kg/m2 vs 21,5 ± 3,7kg/m2). Níveis mais elevados de IL-6 foram observados naqueles localizados no IQD-R T1 (1.345 mg/L vs 1.205 mg/L). No mesmo grupo (T1), os adolescentes que apresentaram níveis mais elevados de IL-6 também apresentaram média de IMC mais elevada (23,6 ± 5,1kg/m2 vs 20,8 ± 3,0kg/m2). Os adolescentes nos maiores tercis de IQD-R (T2 e T3) e que apresentaram maiores concentrações de IL-6 e CR-us também apresentaram maior IMC médio (23,8 ± 4,9kg/m2). Conclusões: A qualidade da dieta dos adolescentes estudados necessita de modificações. As médias do IMC variaram com a qualidade da dieta e os níveis de IL-6 e PCR-us(AU)

Are pre-operative anthropometric parameters helpful in predicting length and thickness of quadrupled hamstring graft for ACL reconstruction in adults? A prospective study and literature review.

PURPOSE: Cross-sectional diameter of 7 mm or more of graft in anterior cruciate ligament reconstruction is arguably the single most important factor determining the success of the operation. Pre-operative anthropometric parameters have been reported to correlate with diameter of quadrupled hamstring graft, which is the most popular graft choice today. We conducted this prospective study to determine the value of some anthropometric measurements to predict the length of harvested semitendinosus and gracilis tendons and quadrupled hamstring graft diameter. We also assessed the reliability of the mathematical equation in accurately predicting the graft diameter. METHODS: Height, weight, BMI and thigh length of 160 patients who underwent primary ACL reconstruction was measured before surgery. Using multivariate logistic regression analysis length of harvested semitendinous and gracilis tendons along with quadrupled graft diameter were correlated to height, weight, BMI and thigh length. RESULTS: Ninety-six percent had graft diameter of 7 mm or more. Height and thigh length were found to be most strongly correlating to both the length of harvested tendons and the quadrupled graft diameter (p ≤ 0.001, r = 0.25-0.39). Patients with height less than 147 cm were found to be at highest risk for inadequate graft diameter (less than 7 mm). Although the anthropometric parameters were found to be significantly related to height and thigh length, the strength of association is moderate. The mathematical equation for prediction of graft diameter using height was found to inaccurately over-predict the graft diameter in 33.1 % of cases, assessed using Bland-Altman plot. CONCLUSION: Anthropometric parameters, especially height and thigh length, can serve as a guide to plan hamstring graft diameter and length before ACL reconstruction. But, it is not advisable to rely on mathematical equations for absolute values of graft parameters as there is risk of over-estimating hamstring length or graft thickness.
