BACKGROUND
It has been suggested that chronic pancreatitis (CP) may be an independent risk factor for development of cardiovascular disease (CVD). At the same time, it seems that congestive heart failure (CHF) and CP share the responsibility for the development of important clinical conditions such as sarcopenia, cachexia and malnutrition due to development of cardiac cachexia and pancreatic exocrine insufficiency (PEI), respectively.
AIM
To explore the evidence regarding the association of CP and heart disease, more specifically CVD and CHF.
METHODS
A systematic search of MEDLINE, Web of Science and Google Scholar was performed by two independent investigators to identify eligible studies where the connection between CP and CVD was investigated. The search was limited to articles in the English language. The last search was run on the 1st of May 2019. The primary outcomes were: (1) Incidence of cardiovascular event [acute coronary syndrome (ACS), chronic coronary disease, peripheral arterial lesions] in patients with established CP; and (2) Incidence of PEI in patients with CHF.
RESULTS
Out of 1166 studies, only 8 were eligible for this review. Studies regarding PEI and CHF showed an important incidence of PEI as well as associated malabsorption of nutritional markers (vitamin D, selenium, phosphorus, zinc, folic acid, and prealbumin) in patients with CHF. However, after substitution of pancreatic enzymes, it seems that, at least, loss of appetite was attenuated. On the other side, studies investigating cardiovascular events in patients with CP showed that, in CP cohort, there was a 2.5-fold higher incidence of ACS. In another study, patients with alcohol-induced CP with concomitant type 3c diabetes had statistically significant higher incidence of carotid atherosclerotic plaques in comparison to patients with diabetes mellitus of other etiologies. Earlier studies demonstrated a marked correlation between the clinical symptoms in CP and chronic coronary insufficiency. Also, statistically significant higher incidence of arterial lesions was found in patients with CP compared to the control group with the same risk factors for atherosclerosis (hypertension, smoking, dyslipidemia). Moreover, one recent study showed that PEI is significantly associated with the risk of cardiovascular events in patients with CP.
CONCLUSION
Current evidence implicates a possible association between PEI and malnutrition in patients with CHF. Chronic pancreatic tissue hypoxic injury driven by prolonged splanchnic hypoperfusion is likely to contribute to malnutrition and cachexia in patients with CHF. On the other hand, CP and PEI seem to be an independent risk factor associated with an increased risk of cardiovascular events.

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.

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.

PURPOSE
Almost all CKD patients have a poor nutritional status, while elderly CKD patients are specifically frail and malnourished. Our aim is to conduct a systematic review of the up to date primary studies that look at methods of improving nutritional status in CKD patients in the elderly demographic.
METHODS
A focussed and sensitive search strategy was applied to the PUBMED database to identify relevant English language articles. Once articles were identified a detailed quality and bias assessment was performed. Two independent researchers (MZ and SM) then subsequently carried out detailed data extraction and analysis and this was subsequently verified by a third researcher (IN).
RESULTS
A total of 19 studies were included in our systematic review which included 7 non-randomised control trials and 15 randomised controlled trials. The outcomes that we considered to be most relevant for our subject title were: mortality data, SGA, albumin, total protein, isoleucine, leucine, prealbumin, transferrin, leptin, valine, TAG, HDL, LDL and total amino acids. Detailed bias analysis of the different studies was also conducted.
CONCLUSION
This is the first systematic review of the literature, so far, on the subject, involving elderly CKD patients. The quality of trials is low, very heterogenic in patients, methods and outcomes. However, we found a positive effect of dietary interventions on the nutritional status of most patients studied, highlighted by improvement in serum albumin and SGA, the most measured outcomes.

Associations between omega-3 polyunsaturated fatty acids supplementation and surgical prognosis in patients with gastrointestinal cancer: A systematic review and meta-analysis.
BACKGROUND
Surgical resection remains the primary treatment for gastrointestinal (GI) cancer, omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been reported to improve the prognosis of patients undergoing gastrointestinal tumor surgery. This meta-analysis aims to explore the efficacy of n-3 PUFAs on GI cancer patients undergoing surgery.
METHODS
A systematic search of PubMed, Cochrane Library databases, EMBASE (until December 2021) was conducted. PRISMA checklist was followed. The data were analyzed by RevMan v5.3.0.
RESULTS
A total of ten RCTs articles including 663 patients were studied. The analysis demonstrated that the n-3 PUFAs group significantly reduced levels of interleukin-6 (IL-6) (P = 0.001), C-reactive protein (CRP) (P < 0.00001), tumor necrosis factor-ɑ (TNF-α) (P = 0.0003) compared with the control group. and higher levels of CD4T cells (P = 0.03), CD8T cells (P = 0.02) and CD4/CD8ratio (P = 0.03) compared with the control group. but there was no significant difference in infection complications rate (P = 0.50) and the level of prealbumin (P = 0.80), albumin (P = 0.21), retinol-binding protein(P = 0.80) between the two groups. In addition, the n-3 PUFAs group significantly reduced the length of hospital stay (P = 0.007).
CONCLUSION
Our meta-analysis shows that n-3 PUFAs can effectively improve the immune function of patients undergoing gastrointestinal cancer surgery, reduce inflammatory response and reduce the length of hospital stay, But it has no significant impact on the incidence of infectious-related complications and the level of nutrient protein.

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.

The liver-derived, circulating transport protein transthyretin (TTR) is the cause of systemic hereditary (ATTRv) and wild-type (ATTRwt) amyloidosis. TTR stabilization and knockdown are approved therapies to mitigate the otherwise lethal disease course. To date, the variety in phenotypic penetrance is not fully understood. This systematic review summarizes the current literature on TTR pathophysiology with its therapeutic implications. Tetramer dissociation is the rate-limiting step of amyloidogenesis. Besides destabilizing TTR mutations, other genetic (RBP4, APCS, AR, ATX2, C1q, C3) and external (extracellular matrix, Schwann cell interaction) factors influence the type of onset and organ tropism. The approved small molecule tafamidis stabilizes the tetramer and significantly decelerates the clinical course. By sequence-specific mRNA knockdown, the approved small interfering RNA (siRNA) patisiran and antisense oligonucleotide (ASO) inotersen both significantly reduce plasma TTR levels and improve neuropathy and quality of life compared to placebo. With enhanced hepatic targeting capabilities, GalNac-conjugated siRNA and ASOs have recently entered phase III clinical trials. Bivalent TTR stabilizers occupy both binding groves in vitro, but have not been tested in trials so far. Tolcapone is another stabilizer with the potential to cross the blood-brain barrier, but its half-life is short and liver failure a potential side effect. Amyloid-directed antibodies and substances like doxycycline aim at reducing the amyloid load, however, none of the yet developed antibodies has successfully passed clinical trials. ATTR-amyloidosis has become a model disease for pathophysiology-based treatment. Further understanding of disease mechanisms will help to overcome the remaining limitations, including application burden, side effects, and blood-brain barrier permeability.

Meta-Analysis
OBJECTIVES
The present systematic review and meta-analysis study evaluated the impact of early enteral nutrition (EN) on postoperative nutritional and immunological outcomes of gastric cancer (GC) patients.
METHOD
The databases of PubMed, Embase, Springer, and Cochrane library were searched till September 2016 to identify studies which evaluated the effects of EN compared with parenteral nutrition (PN) on postoperative immunological and nutritional status and hospitalization time in GC patients. Mean difference (MD) or standard mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis.
RESULTS
The present systematic review and meta-analysis have consisted of seven trials, containing 835 GC patients. According to the result of meta-analysis, compared with PN, EN significantly resulted in more increase in the level of albumin [MD = 2.07 (0.49, 3.64)], prealbumin [MD = 9.41 (049, 33.55)], weight [MD = 1.52 (0.32, 2.72)], CD3+ [SMD = 1.96 (1.50, 2.43)], CD4+ [SMD = 2.45 (1.97, 2.93)], natural killers [MD = 5.80 (3.75, 7.85)], and also a decrease in the hospitalization time [MD=-2.39 (-2.74, -2.03)].
CONCLUSION
The results demonstrated that early administration of EN is more effective in improving postsurgical nutrition status and immune index in GC patients. So, based on these results, postoperative early administration of EN is recommended for GC patients where possible.

Meta-Analysis Review
OBJECTIVE
Transcatheter aortic valve replacement (TAVR) is a successful treatment for aortic stenosis (AS) patients, and previous studies indicate favorable outcomes for those with concomitant aortic stenosis and transthyretin-associated cardiac amyloidosis (TTRCA-AS). However, the impact of TAVR on more adverse outcomes in TTRCA-AS patients compared to those with AS alone is still uncertain, with conflicting findings reported in the literature.
METHODS
PubMed and Scopus were extensively searched from inception till August 2021. Studies were included if they reported data for prevalence and outcomes including mortality and cardiovascular-related hospitalization events in TTRCA-AS patients referred for TAVR. The data for these outcomes were pooled using a random effects model and forest plots were created.
RESULTS
After initially screening 146 articles, 6 were shortlisted for inclusion in our analysis. Pooled analysis demonstrated a 13.3% [95% CI: 10.9-16.5; p = 0.307] prevalence of TTRCA in patients with AS undergoing TAVR. The incidence of mortality and cardiovascular (CV) hospitalization in patients with TTRCA-AS undergoing TAVR were 28.3% [95% CI: 18.7-39.0, p = 0.478] and 21.1% [95% CI: 10.2-34.5, p = 0.211], respectively.
CONCLUSION
The overall pooled TTRCA-AS prevalence was reported to be 13.3% in AS patients who underwent TAVR. Furthermore, transthyretin-associated CA was found to be associated with an increased risk of mortality and hospitalization. Large patient population studies are required to assess the safety and efficacy of TAVR in TTRCA-AS patients, as current research report data from small patient cohorts.

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.
