Review
BACKGROUND
In recent years, the Fibrinogen to pre-albumin ratio (FPR) has been reported in many studies to be significantly associated with the prognosis of various cancers. This systematic review and meta-analysis aimed to investigate the prognostic value of FPR in malignant tumors of the digestive system based on available evidence.
METHODS
The relevant articles published before July 1, 2021, were systematically retrieved from electronic databases to evaluate the effect of Fibrinogen to pre-albumin ratio (FPR) on the prognosis of patients with malignant digestive system tumors and calculate the hazard ratio (HR) and the corresponding 95% confidence interval (CI).
RESULT
Thirteen articles, all from China, including 15 cohort studies and a total of 5116 cases, were included in this study. A high FPR was associated with poor overall survival (HR = 1.88, 95%CI 1.53-2.32, P < 0.001), recurrence-free survival (HR = 2.29, 95%CI 1.91-2.76, P < 0.001), progression-free survival (HR = 1.96, 95%CI: 1.33-2.90, P = 0.001), complications (HR = 1.78, 95%CI: 1.06-3.00, P = 0.029), disease-free survival (HR = 1.46, 95%CI: 1.08-1.97, P = 0.013) was significantly associated with cancer-specific survival (HR = 1.44, 95%CI: 1.15-1.79, P = 0.001). Even though intergroup differences were present, FPR was strongly associated with overall and relapse-free survival, and sensitivity analysis suggested that our results were stable.
CONCLUSION
FPR can be used as a valuable indicator to predict the prognosis of patients with malignant digestive system tumors.

BACKGROUND
The p.Val142Ile variant, predominantly found among people of African descent, is the most common cause of variant transthyretin amyloidosis and carriers predominantly develop a cardiomyopathy (variant transthyretin amyloidosis cardiomyopathy) phenotype. Yet, there are conflicting data on the prevalence and outcomes of p.Val142Ile variant carriers.
METHODS
We performed a systematic review of the prevalence and outcomes of p.Val142Ile variant transthyretin amyloidosis cardiomyopathy among subjects of African descent. We found 62 relevant articles after searching the MEDLINE databases from 1980 to 2020 that reported data for ≈150 000 subjects.
RESULTS
The reported worldwide prevalence of the p.Val142Ile variant is 0.3% to 1.6% in the general population. Among people of African descent, the reported prevalence from all studies ranges from 1.1% to 9.8%, but for studies with >1000 subjects, it is 3% to 3.5%. The prevalence of the p.Val142Ile variant in a region is dependent on the reported percentage of subjects who are of African descent in that region. p.Val142Ile variant transthyretin amyloidosis cardiomyopathy typically presents in the seventh to eighth decade of life and the majority of cases reported were male, with 25% to 38% diagnosed with atrial fibrillation. It was associated with a longitudinally worse quality of life and a lower adjusted survival compared with other types of transthyretin amyloidosis cardiomyopathy.
CONCLUSIONS
The p.Val142Ile variant is the most common variant of the transthyretin gene with most carriers being of African descent. The true penetrance is unknown but the p.Val142Ile variant is associated with increased rates of incident heart failure and portends a lower overall survival. Increased awareness could lead to earlier diagnosis and improved heart failure outcomes among those of African descent, which is of increasing importance given the advent of novel therapeutics for this disease.

Meta-Analysis Review
Structured triglycerides versus physical mixtures of medium- and long-chain triglycerides for parenteral nutrition in surgical or critically ill adult patients: Systematic review and meta-analysis.
INTRODUCTION
New generations of parenteral lipid emulsions combine Long Chain Triglycerides (LCTs) with Medium Chain Triglycerides (MCTs) either by physically mixing MCT- and LCT-containing oils or by using synthetically structured triglycerides (STGs). In order to clarify some open issues relating to their comparative effect, in particular in terms of clinical outcomes, pertinent evidence was systematically identified, reviewed and meta-analyzed.
METHODS
PubMed, Scopus, Wanfang Data, China Hospital Knowledge Database and Google Scholar were searched for published clinical trials comparing STGs vs. MCTs/LCTs PN regimens administered over 5-7 days in surgical and/or critically ill patients. Two independent investigators performed screening and data extraction using a predefined list of parameters. Data were pooled using RevMan 5.2. Quality of evidence was assessed according to Cochrane's risk of bias tool. Pre-specified high quality (HQ), incremental analyses and a post hoc subgroup analysis were performed.
RESULTS
21 studies were included. The meta-analysis revealed a significantly better cumulative nitrogen balance (Std. mean difference [95% CI]) (1.34 [0.98-1.7], p < 0.00001), as well as higher values for pre-albumin (24.99 mg/L [6.71-43.27], p < 0.000001), and albumin (1.22 g/L [0.66-1.77] p < 0.0001), while plasma triglycerides were significantly lower (-0.28 mmol/L [-0.41 to -0.15], p < 0.0001) in the STG vs. MCT/LCT group. ALT, AST, and GGT were significantly lower with STGs than with MCTs/LCTs, while for total bilirubin and ALP only a trend was observed. STGs were also associated with a trend to a shorter hospital length of stay (LOS) (-1.74 days [-3.49 to 0.01] p = 0.05). Quality of evidence was affected by an unclear risk of selection bias, mostly due to the lack of detailed reporting (random sequence generation, allocation concealment). For the other domains, most of the weighted information was judged at low risk of bias. HQ estimated effects, incremental and subgroup analyses were consistent with the main analysis.
CONCLUSIONS
In postsurgical and/or critically ill patients, the administration of STGs vs. MCT/LCTs was significantly associated with improved protein economy, better liver tolerance and a more efficient triglyceride elimination. With regard to clinical outcomes a strong trend towards reduced LOS was observed for STG patients.

Efficacy of early enteral nutrition versus total parenteral nutrition for patients with gastric cancer complicated with diabetes mellitus: A systematic review and meta-analysis.
AIM
This study aimed to synthesise available data and evaluate the clinical evidence regarding the effect of early enteral nutrition versus total parenteral nutrition on nutritional status and blood glucose in patients with gastric cancer complicated with diabetes mellitus after gastrectomy.
METHODS
This systematic review and meta-analysis was designed, conducted and reported following the PRISMA guideline. We performed searches in PubMed, Embase, Medline, Web of Science, Cochrane Library, Chinese Biomedicine Literature Database, Chinese Scientific Journal Database, Chinese National Knowledge Infrastructure and Wanfang Database. The study designs were randomised controlled trials, quasi-randomised controlled trials, and controlled clinical trials. The trials compared early enteral nutrition (experimental group) with total parenteral nutrition (control group) in patients with gastric cancer complicated with diabetes mellitus after gastrectomy. The risk of bias was assessed using the Cochrane risk of bias tool.
RESULTS
A total of 19 trials (1255 patients) were included. Meta-analysis showed a significantly shorter length of hospital stay (days; mean difference -5.07, 95% confidence interval [CI] [-6.28, -3.86], p < 0.00001) and a lower post-operative complications rate (%; odds ratio 0.29, 95% CI [0.16, 0.50], p < 0.0001) in the early enteral nutrition group than in the total parenteral nutrition group. Compared with the total parenteral nutrition group, the early enteral nutrition group had lower blood glucose fluctuation values (mmol/L; mean difference -2.03, 95% CI [-2.44, -1.61], p < 0.00001), lower levels of glycosylated haemoglobin (%; mean difference -0.62, 95% CI [-1.22, -0.03], p = 0.04), higher levels of prealbumin (g/L; p = 0.002), transferrin (g/L; p = 0.002), total protein (g/L; p = 0.001) and haemoglobin (g/L; p = 0.005).
CONCLUSIONS
Early enteral nutrition may maintain stable blood glucose levels and improve nutritional status, leading to better therapeutic effectiveness in gastric cancer complicated with diabetes mellitus patients.

Meta-Analysis
CONTEXT
Low serum albumin and pre-albumin concentrations are associated with edema, infection, thrombosis, heart failure, and mortality.
OBJECTIVE
This comprehensive systematic review and meta-analysis of clinical trials was conducted to summarize the available findings on the impact of omega-3 supplementation on albumin, pre-albumin, and the C-reactive protein/albumin ratio in hospitalized patients.
DATA SOURCES
PubMed, Web of Science, Scopus, and Google Scholar databases were searched from January 1990 to October 2021.
DATA EXTRACTION
Extracted data from 50 randomized controlled trials (RCTs) with a total number of 3196 participants were analyzed using the random-effects model. The dose-dependent effect was also evaluated.
DATA ANALYSIS
Oral omega-3 supplementation significantly increased serum albumin concentrations in patients with cancer (weighted mean difference [WMD]: 0.19; 95% CI: 0.05, 0.33, P= 0.006), patients on dialysis (WMD: 0.14; 95% CI: 0.01, 0.28, P= 0.042), and those with hypoalbuminemia (WMD: 0.38; 95% CI: 0.03, 0.72, P = 0.033); however, there was no significant effect among patients with gastrointestinal or hepatologic diseases. Moreover, each 1000 mg/day increase in oral omega-3 supplementation resulted in elevated serum albumin levels in cancer patients (WMD: 0.15; 95% CI: 0.07, 0.24, P < 0.001). In addition, a favorable effect of oral omega-3 supplementation on pre-albumin levels was observed among patients with cancer (WMD: 33.87; 95% CI: 12.34, 55.39, P = 0.002). A similar significant effect of parenteral omega-3 supplementation on pre-albumin concentrations was seen among those with gastrointestinal and hepatologic diseases as well (WMD: 23.30; 95% CI: 13.58, 33.03, P < 0.001). No significant effect of oral omega-3 supplementation on the CRP/albumin ratio was found.
CONCLUSIONS
Overall, omega-3 fatty acids supplementation resulted in a favorable change in serum albumin and pre-albumin concentrations in hospitalized patients.

Meta-Analysis Review
AIM
3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) may have an adjunctive effect on chronic inflammation and nutrition status in renal dialysis patients. Therefore, we performed a systematic review of randomized controlled trials to assess the effect of statins on chronic inflammation and nutrition status in dialysis patients.
METHODS
The randomized controlled trials (RCTs) of statins versus placebo or no treatment for renal dialysis patients were searched from PubMed, EMbase and Cochran Central Register of Controlled Trials. We screened relevant studies according to predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed meta-analyses by using the Cochrane Collaboration's Revman 5.1 software.
RESULTS
We identified nine trials including 3098 patients. Meta-analysis showed statins can significantly decrease the serum C-reactive protein (CRP) (SMD, -0.54; 95% confidence interval (CI), -1.04 to -0.05; P = 0.03) and high sensitivity CRP (hs-CRP) level (SMD, -0.72; 95% CI, -1.14 to -0.31; P = 0.0007) of dialysis patients compared with that of the control group. However, statins did not differ significantly from the control group in increasing the serum Alb level (SMD, -0.13; 95% CI, -0.42 to 0.15; P = 0.37).
CONCLUSIONS
Statins can improve the chronic inflammation status reflected by the decreasing of serum CRP and hs-CRP levels, whereas there is no conclusive evidence that it can improve the nutrition status. However, this result needs to be further confirmed in more high-quality randomized clinical trials.

Effects of early postoperative enteral nutrition versus usual care on serum albumin, prealbumin, transferrin, time to first flatus and postoperative hospital stay for patients with colorectal cancer: A systematic review and meta-analysis.
BACKGROUND
Early enteral nutrition (EEN) after surgery had been reported to decrease morbidity and mortality. However, no meta-analysis performed on nutrition status and recovery after surgery to Colorectal cancer (CRC).
AIM
We aimed to estimate effect of EEN for postoperative CRC.
METHODS
Electronic databases were searched for randomized controlled trials published prior to September 2017. Papers comparing EEN after surgery to traditional nutritional regimen in CRC patients were selected. The chosen articles should containe one or more of the following outcome measures: serum albumin, prealbumin, transferrin, time to first flatus and postoperative hospital stay.
RESULTS
2307 cases from 26 studies were included. The analysis showed that EEN was more effective in increasing serum albumin and prealbumin, promoting the recovery of gastrointestinal function, and decreasing the time of postoperative hospital stay, especially for colon cancer.
CONCLUSION
EEN can improve nutritional status and promote intestinal function recovery for patients undergoing CRC surgery.

Meta-Analysis
BACKGROUND
Not only has the placement rate of enteral feeding tubes during operations for esophageal cancer increased, but also has number of patients who choose to continue enteral feeding at home instead of removing the feeding tube at discharge. The impacts of home enteral nutrition (HEN) after esophagectomy in esophageal cancer patients are analyzed.
METHODS
A systematic review was conducted in accordance with PRISMA and Cochrane guidelines. English and Chinese databases, including PubMed, Embase, Web of Science, The Cochrane Library, Scopus, CBM, CNKI, and Wan Fang were searched from inception to December 7, 2019. Randomized controlled trials evaluating the short-term outcomes of HEN following esophagectomy in cancer patients were included. The risk of bias of the included studies was appraised according to the Cochrane risk of bias tool. The summary of relative risk/weighted mean difference (WMD) estimates and corresponding 95% confidence interval (95% CI) were calculated using fixed- and random-effects models.
RESULTS
Nine randomized controlled trials involving 757 patients were included in the meta-analysis. Compared with oral diet, HEN was associated with significantly increased body weight (WMD 3 kg, 95% CI 2.36-3.63, P < .001), body mass index (WMD 0.97 kg/m, 95% CI 0.74-1.21, P < .001), albumin (WMD 3.43 g/L, 95% CI 2.35-4.52, P < .001), hemoglobin (WMD 7.23 g/L, 95% CI 5.87-8.59, P < .001), and total protein (WMD 5.13 g/L, 95% CI 3.7-6.56, P < .001). No significant differences were observed in prealbumin and gastrointestinal adverse reactions. Physical (WMD 8.82, 95% CI 6.69-10.95, P < .001) and role function (WMD 12.23, 95% CI 2.72-21.74, P = .01) were also significantly better in the HEN group. The nausea/vomiting (WMD -5.43, 95% CI -8.29 to -2.57, P = .002) and fatigue symptoms (WMD -11.76, 95% CI -16.21 to -7.32, P < .001) were significantly reduced. Appetite loss (WMD -8.48, 95% CI -14.27 to -4.88, P = .001), diarrhea (WMD -3.9, 95% CI -7.37 to -0.43, P = .03), and sleep disturbance (WMD -7.64, 95% CI -12.79 to -2.5, P = .004) in the HEN group were also significantly less than the control group.
CONCLUSIONS
HEN improved nutrition status, physical and role function, and reduced nausea/vomiting, fatigue, appetite loss, diarrhea, and sleep disturbance compared with an oral diet in esophageal cancer patients postsurgery. HEN did not increase adverse reactions.

Neurosurgery Oct 2021Preoperative malnutrition has been implicated in adverse events after elective surgery, potentially impacting patient outcomes.
BACKGROUND
Preoperative malnutrition has been implicated in adverse events after elective surgery, potentially impacting patient outcomes.
OBJECTIVE
As a potentially modifiable risk factor, we sought to determine which assessments of nutritional status were associated with specific adverse events after spine surgery. In addition, we explored if a preoperative nutritional improvement intervention may be beneficial in lowering the rates of these adverse events.
METHODS
The literature search yielded 115 abstracts relevant to the PICO (patient/population, intervention, comparison, and outcomes) questions included in this chapter. The task force selected 105 articles for full text review, and 13 met criteria for inclusion in this systematic review.
RESULTS
Malnutrition, assessed preoperatively by a serum albumin <3.5 g/dL or a serum prealbumin <20 mg/dL, is associated with a higher rate of surgical site infections (SSIs), other wound complications, nonunions, hospital readmissions, and other medical complications after spine surgery. A multimodal nutrition management protocol decreases albumin and electrolyte deficiencies in patients with normal preoperative nutritional status. It also improves overall complication rates but does not specifically impact SSIs.
CONCLUSION
It is recommended to assess nutritional status using either serum albumin or prealbumin preoperatively in patients undergoing spine surgery.The full guidelines can be accessed at https://www.cns.org/guidelines/browse-guidelines-detail/4-preoperative-nutritional-assessment.

Meta-Analysis
Enhanced Recovery Program (ERP) is a multimodal perioperative protocol. Its feasibility and benefits on short term outcomes have been widely reported. These well described improvements, like shorter length of stay and early resumption of body's functions, represent the consequence of an attenuated surgical stress response (SSR). When this response is uncontrolled, it leads to postoperative complications and poor long-term outcomes. SSR can be easily monitored through the analyses of mediators in the bloodstream. Available evidences do not achieve to tell if ERP allows a measurable surgical stress reduction. In this review, we searched for papers investigating the surgical stress response and ERP applied to elective mini-invasive procedures, in order to better understand the level of evidence regarding the effectiveness of ERP in minimizing the surgical stress response. A systematic review of published literature was performed using PubMed, Cochrane, EMBASE and Google Scholar database, following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Included studies concerned SSR analysis in ERP patients undergoing laparoscopic surgery through different surgical specialties. Eight studies with a total of 632 patients were included. The three steps of SSR, endocrine, inflammatory and nutritional were all reported in the papers included in this review. Results showed no powerful evidence of difference in endocrine phase while an attenuated inflammatory response was reported for ERP patients when Interleukin-6 (IL-6) and C Reactive Protein (CRP) were dosed. Nutritional status was also preserved as albumin, pre-albumin and transferrin had better values in these patients. ERP applied to different types of laparoscopic surgery has a role in reducing SSR. This can be shown by the analysis of mediators such as IL-6, CRP and nutritional markers.
