RESUMEN
BACKGROUND: Meta-analyses have primarily focused on the effects of exercise-based prehabilitation on postoperative outcomes and ignored the role of nutritional intervention. In this study, we filled this gap by investigating the effect of nutrition-based prehabilitation on the postoperative outcomes of patients who underwent esophagectomy and gastrectomy. METHODS: Five electronic databases, namely, PubMed, the Web of Science, Embase, Cochrane Library, and CINAHL, were searched. Adults diagnosed with esophagogastric cancer who were scheduled to undergo surgery and had undergone uni- or multimodal prehabilitation, with at least a week of mandatory nutritional intervention, were included. Forest plots were used to extract and visualize the data from the included studies. The occurrence of any postoperative complication was considered the primary endpoint. RESULTS: Eight studies met the eligibility criteria, with five randomized controlled trials (RCTs) and three cohort studies. In total, 661 patients were included. Any prehabilitation, that is, unimodal (only nutrition) and multimodal prehabilitation, collectively decreased the risk of any postoperative complication by 23% (95% confidence interval [CI] = 0.66-0.90). A similar effect was exclusively observed for multimodal prehabilitation (risk ratio [RR] = 0.78, 95% CI = 0.66-0.93); however, it was not significant for unimodal prehabilitation. Any prehabilitation significantly decreased the length of hospital stay (LOS) (weighted mean difference = -0.77, 95% CI = -1.46 to -0.09). CONCLUSIONS: Nutrition-based prehabilitation, particularly multimodal prehabilitation, confers protective effects against postoperative complications after esophagectomy and gastrectomy. Our findings suggest that prehabilitation slightly decreases LOS; however, the finding is not clinically significant. Therefore, additional rigorous RCTs are warranted for further substantiation.

BACKGROUND: Lung adenocarcinoma is a high-mortality rate cancer. Within this category, Lung mucinous adenocarcinoma (LMAC) is a rare and distinct subtype of lung adenocarcinoma necessitating further investigation. The study was launched to compare the difference of survival features between LMAC and lung non-mucinous adenocarcinoma (LNMAC) and to investigate the significance and demand for developing a new staging system tailored to LMAC. METHODS: This retrospective study assessed the suitableness of the current staging system for LMAC. It compared the overall survival (OS) between LMAC and LNMAC from 2004 to 2020 (LNMAC: 160,387; LMAC: 6,341) and instituted a novel classification framework for LMAC based on US population. Verification group consisting of patients from two Chinese medical centers from 2010 to 2018 (n = 392) was set to ascertain the applicability of this novel system. The primary endpoint was OS. To minimize the bias, propensity score match (PSM) was employed. Survival analysis and Log-rank test were executed to explore the survival features of LMAC. RESULTS: The results indicated that the existed staging system was not suitable for LMAC. Patients diagnosed with LMAC exhibited a superior OS compared to those with LNMAC in stage IA2 (P < 0.0001), IA3 (P < 0.0001), IB (P = 0.0062), IIA (P = 0.0090), IIB (P = 0.0005). In contrast, a worse OS in stage IVA (P = 0.0103) was found in LMAC patients. The novel classification system proposed for LMAC proved to be highly applicable and demonstrated substantial efficacy, as confirmed by the verification group. CONCLUSION: The newly established classification system was more effective for LMAC, but it necessitates large-scale verification to confirm its applicability and reliability.

OBJECTIVES: The merits of early enteral nutrition (EEN) in patients in the cardiothoracic intensive care unit (CTICU) remain unclear. This retrospective study aimed to address this issue. METHODS: We analyzed data from the MIMIC IV v2.0 database, including patients with a CTICU stay of ≥4 d. Patients were divided into early and delayed enteral nutrition (EN) groups. Differences in baseline data were corrected using an inverse probability weighting (IPW) approach. Generalized linear models (GLMs) were used to compare trends over time between groups, and survival effects were evaluated with weighted logistic and Cox regression, supplemented by weighted Kaplan-Meier curves. Subgroup analysis facilitated the exploration of potential interactions. RESULTS: The study included 720 CTICU patients. Following IPW, all baseline variables were balanced. EEN led to shorter hospital and CTICU stays, lower incidence of respiratory and blood infections, and reduced total insulin usage in the first week of CTICU admission, albeit with an increased total gastric residual volume. Mortality risk between the groups did not significantly differ at 28 d or at 1 y. Excessive early energy and protein intake elevated the risk of 28-d mortality, but the relationship may not be linear. Overweight patients or those with fewer comorbidities had a higher mortality risk with EEN. CONCLUSIONS: EEN may improve short-term outcomes in CTICU patients without a clear survival benefit. Early high caloric and protein intake could lead to adverse outcomes, suggesting a careful evaluation for initiating EN in specific patients.

BACKGROUND: The type and placement of chest tube for patients undergoing uniportal video-assisted thoracoscopic lobectomy remains controversial. The aim of this study was to assess the efficacy and safety of a novel technique in which a pigtail catheter was used alone as the chest tube and placed near the incision for chest drainage after uniportal video-assisted thoracoscopic lobectomy and extended lymphadenectomy. METHODS: A total of 217 patients undergoing uniportal video-assisted thoracoscopic lobectomy were retrospectively reviewed and divided into two groups. In group A, a 12-Fr pigtail catheter with several side ports was placed next to the uniportal wound. In group B, a conventional 20-Fr chest tube was placed through the uniportal wound itself. Postoperative complications related to chest tube placement and patients' subjective satisfaction were compared between the two groups. Postoperative pain management effect and other clinical outcomes such as duration of chest drainage and postoperative stay were also compared. RESULTS: There were 112 patients in group A and 105 patients in group B. A significantly lower incidence of wound complications was found in group A postoperatively (p = 0.034). The pain score on coughing in group A was significantly lower than that in group B on postoperative day two (POD2) (p = 0.021). There was no significant difference of other clinical outcomes such as duration of chest drainage and postoperative stay as well as major complications between the two groups. CONCLUSION: Placing a 12-Fr pigtail catheter alone next to the uniportal wound for chest drainage might be effective and safe after uniportal video-assisted thoracoscopic lobectomy and extended lymphadenectomy.

OBJECTIVES: Esophageal cancer is a high-mortality disease. Esophagectomy is the most effective method to treat esophageal cancer, accompanied with a high incidence of post-operation complications. The anastomosis has a close connection to many severe post-operation complications. However, it remains controversial about the choice of intrathoracic anastomosis (IA) or cervical anastomosis (CA). The study was conducted to compare the clinical outcomes between the two approaches. METHODS: We searched databases for both randomized controlled trials (RCTs) and cohort studies comparing post-operation outcomes between IA and CA. Primary outcomes were the incidences of anastomotic leakage and mortality. Secondary outcomes were the incidences of anastomotic stenosis, pneumonia and re-operation. RESULTS: Twenty studies with a total of 7,479 patients (CA group: n = 3,183; IA group: n = 4296) were included. The results indicated that CA group had a higher incidence of anastomotic leakage than IA group (odds ratio [OR] = 2.05, 95% confidence intervals [CI] = 1.61-2.60, I2 = 53.31%, P < 0.01). Subgroup analyses showed that CA group had higher incidences of type I (OR = 2.19, 95%CI = 1.05-4.57, I2 = 0.00%, P = 0.04) and type II (OR = 2.75, 95%CI = 1.95-3.88, I2 = 1.80%, P < 0.01) anastomotic leakage than IA group. No difference was found in type III anastomotic leakage (OR = 1.23, 95%CI = 0.82-1.86, I2 = 20.92%, P = 0.31). The 90-day mortality (OR = 1.66, 95%CI = 1.11-2.47, I2 = 0.0%, P = 0.01) in IA group were lower than that in CA group. No difference was found in in-hospital mortality (OR = 1.31, 95%CI = 0.91-1.88, I2 = 0.00%, P = 0.15) and 30-day mortality (OR = 1.08, 95%CI = 0.69-1.70, I2 = 0.00%, P = 0.74). CONCLUSIONS: IA might be a better anastomotic approach than CA, with a lower incidence of anastomosis leakage and no increase in short-term mortality. Significant heterogeneity and publication bias might limit the reliability of the results. More high-quality studies are needed to verify and update our findings.

BACKGROUND: It remains unclear whether enteral nutrition (EN) has an impact on prognosis and immune nutritional status for patients in the cardiothoracic surgery recovery unit (CSRU). We hypothesized that only patients with specific characteristics would benefit from EN and aimed to distinguish that specific population by examining a large database. METHODS: Propensity-score matching (PSM) was used to eliminate the baseline imbalances between the EN and non-EN groups. The modified nutritional risk in the critically ill (mNUTRIC) score was used to assess the severity of patients' disease as well as their nutritional risk. Kaplan-Meier curves were used to compare the differences in 28- and 1000-day overall survival in the two groups after PSM. Generalized additive mixed models (GAMMs) were used to show dynamic changes in neutrophil-to-lymphocyte ratios (NLRs) and platelet-to-lymphocyte ratios (PLRs) in the two groups. Subgroup analysis was used to identify the specific population that could benefit from EN. RESULTS: A total of 1823 patients (EN group, n = 395; non-EN group, n = 1428) were enrolled; after PSM, 320 pairs of patients remained. EN was found to reduce the 28-day mortality rate (adjusted hazard ratio [HR] = .56; 95% CI, .35-.91; P = .019) of patients, whereas it had no effect on 1000-day survival (adjusted HR = .97; 95% CI, .75-1.25; P = .797). Subgroup analyses indicated that patients with mNUTRIC equal to or greater than 4, body mass index (BMI) 25-30 kg/m2, and vasopressor support were more likely to benefit from EN. NLR and PLR in the EN group decreased progressively over time compared with the non-EN group, suggesting that EN might improve clinical outcomes by regulating immune and inflammatory responses. CONCLUSION: EN may improve the prognosis and immune nutritional status of patients in the CSRU. Patients who might benefit should be actively treated with EN.

BACKGROUND & AIMS: Sarcopenia is associated with poor clinical outcomes of patients who underwent esophagectomy. The current diagnostic criteria for sarcopenia are complex and laborious. We aimed to employ the simple and economic indicator sarcopenia index (SI = creatinine/cystatin C ×100) to screen for sarcopenia and to evaluate its prognostic value in patients with esophageal cancer (EC). METHODS: Older participants in the National health and nutrition examination survey (NHANES) database (1999-2002) were divided into three groups according to tertiles of the SI value to explore the feasibility of SI in the diagnosis of sarcopenia. Restricted cubic spline (RCS) was utilized to show the non-linear relationship between all-cause mortality and SI. Patients with EC admitted to Jinling Hospital were enrolled to validate the efficacy and prognostic value of SI. Cut-off values of SI were determined using receiver operating characteristic curves. Multivariable logistic analyses and Cox analyses were used to identify the independent factors of postoperative complications and long-term survival, respectively. RESULTS: A total of 989 participants were identified from the NHANES database. SI showed the diagnostic value of sarcopenia (tertile 1 vs. tertile 3: odds ratio [OR]=3.67, 95% confidence interval [CI]: 1.52-8.87, p=0.004; tertile 2 vs. tertile 3: OR=1.79, 95% CI: 0.75-4.28, p=0.191) adjusted for race, gender, and body mass index (BMI). Individuals with SI ≤ 68 had a poorer overall survival (OS) (hazard ratio [HR]=2.14, 95% CI: 1.71-2.68, p<0.001), and the RCS plot showed that the all-cause mortality risk gradually decreased with the increase in SI. Then, 203 patients with EC were enrolled, of which 76 patients were diagnosed with sarcopenia. There was a linear correlation between SI and skeletal muscle index and prealbumin, indicating that SI was reliable for diagnosing sarcopenia. Patients in the high sarcopenia risk group (Male: SI < 62; Female: SI < 55) showed a higher incidence of complications (OR=3.50, 95% CI: 1.85-6.61, p<0.001) and poorer long-term survival (HR=2.62, 95% CI: 1.02-6.77, p=0.046). CONCLUSION: SI could be used to identify sarcopenia in patients with EC, and it is a useful prognostic factor of postoperative complications and long-term survival.

Epilepsy is a chronic neurological disorder often associated with recurrent seizures. A growing body of evidence suggests that seizures cause structural and functional alterations of the brain. It is reported that behavioral abnormalities frequently occur in patients with epilepsy and experimental epilepsy models. However, the precise pathological mechanisms associated with these epilepsy comorbidities remain largely unknown. Neurogenesis persists throughout life in the hippocampal dentate gyrus (DG) to maintain proper brain function. However, aberrant neurogenesis usually generates abnormal neural circuits and consequently causes neuronal dysfunction. Neuroinflammatory responses are well known to affect neurogenesis and lead to aberrant reorganization of neural networks in the hippocampal DG. Here, in this study, we observed a significant increase in neuroinflammation and in the proliferation and survival of newborn granular cells in the hippocampus of pilocarpine-induced status epilepticus (SE) mice. More importantly, these proliferating and surviving newborn granular cells are largely ectopically located in the hippocampal DG hilus region. Our behavior test demonstrated that SE mice displayed severe aggressive behavior. Pharmacological inhibition of neuroinflammation, however, suppressed the ectopic neurogenesis and countered the enhanced aggressive behavior in SE mice, indicating that seizure-induced neuroinflammation may contribute to ectopic neurogenesis and aggressive behavior in SE mice. These findings establish a key role for neuroinflammation in seizure-induced aberrant neurogenesis and aggressive behavior. Suppressing neuroinflammation in the epileptic brain may reduce ectopic neurogenesis and effectively block the pathophysiological process that leads to aggressive behavior in TLE mice.
