Dietary intervention for adult survivors of cancers other than breast cancer: A systematic review.

INTRODUCTION: Healthy eating and weight control are recommended for cancer survivors; however, dietary interventions are not routinely offered to them. This study aimed to assess the effects of dietary interventions on survival, nutritional status, morbidity, dietary changes, health-related quality of life (QOL), and clinical measures in cancer survivors. METHODS: Searches were conducted from October 1, 2018 to November 21, 2011 in the Medline, EMBASE, CENTRAL, Emcare, and DARE electronic databases. We included randomized controlled trials (RCTs) that involved individuals diagnosed with cancer, excluding conference abstracts, case studies, other reviews, and meta-analyses, and screened the articles. RESULTS: Eight studies were included in this meta-analysis. We observed significant improvements in QOL and clinical data in 3 of 6 studies and in one study, respectively, significant weight loss on anthropometry in 2 of 5 studies, and dietary improvement in 4 of 5 studies of adult cancer survivors. However, we did not observe any benefits of dietary intervention for cancer survivors with undernutrition. DISCUSSION: Dietary interventions for adult cancer survivors might contribute to improving their nutritional status; however, further clarification requires a study that standardizes the intervention method. Furthermore, RCTs are required to determine the effects on cancer survivors with undernutrition.

Impact of Perioperative Immunonutrition on Postoperative Outcomes for Patients Undergoing Head and Neck or Gastrointestinal Cancer Surgeries: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: To clarify whether perioperative immunonutrition is effective in adult patients with or without malnutrition undergoing elective surgery for head and neck (HAN) or gastrointestinal (GI) cancers. BACKGROUND: It is important to avoid postoperative complications in patients with cancer as they can compromise clinical outcomes. There is no consensus on the efficacy of perioperative immunonutrition in patients with or without malnutrition undergoing HAN or GI cancer surgery. MATERIALS AND METHODS: We searched MEDLINE (PubMed), MEDLINE (OVID), EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Selection, and Emcare from 1981 to 2022 using search terms related to immunonutrition and HAN or GI cancer. We included randomized controlled trials. Intervention was defined as immunonutritional therapy including arginine, n-3 omega fatty acids, or glutamine during the perioperative period. The control was defined as standard nutritional therapy. The primary outcomes were total postoperative and infectious complications, defined as events with a Clavien-Dindo classification grade ≥ II that occurred within 30 days after surgery. RESULTS: Of the 4825 patients from 48 included studies, 19 had upper GI cancer, 9 had lower, and 8 had mixed cancer, whereas 12 had HAN cancers. Immunonutrition reduced the total postoperative complications (relative risk ratio: 0.78; 95% CI, 0.66-0.93; certainty of evidence: high) and infectious complications (relative risk ratio: 0.71; 95% CI, 0.61-0.82; certainty of evidence: high) compared with standard nutritional therapy. CONCLUSIONS: Nutritional intervention with perioperative immunonutrition in patients with HAN and GI cancers significantly reduced total postoperative complications and infectious complications.

Comparative Efficacy of Granisetron and Droperidol After Orthognathic Surgery for Prophylaxis of Postoperative Nausea and Vomiting: A Retrospective Study.

BACKGROUND: In the fall of 2021, granisetron was approved for postoperative nausea and vomiting (PONV) management in Japan. However, the comparative efficacy of droperidol and granisetron in the field of orthognathic surgery has not been determined. PURPOSE: We compare the efficacy of droperidol and granisetron for PONV prophylaxis following orthognathic surgery. STUDY DESIGN, SETTING, SAMPLE: We performed a retrospective cohort study of patients who underwent orthognathic surgery at a single institution from September 2020 to December 2022. Patients who had undergone Le Fort I osteotomy with sagittal split ramus osteotomy or isolated sagittal split ramus osteotomy were included. Patients were divided into three groups; the isolated droperidol (D), isolated granisetron (G), and droperidol with granisetron (DG) groups. General anesthesia was performed using total intravenous anesthesia for all patients; however, droperidol and granisetron were administered at the anesthesiologist's discretion. PREDICTOR VARIABLE: PONV prophylactic therapy included isolated droperidol, isolated granisetron, and droperidol with granisetron administration. OUTCOME VARIABLES: Postoperative nausea (PON) and postoperative vomiting (POV) were determined through medical examination within 48 hours following surgery. Secondary outcomes included complications due to droperidol and/or granisetron administration. COVARIATES: Age, sex, body mass index, Apfel's score, duration of surgery, duration of anesthesia, intraoperative blood loss, and type of surgery. ANALYSES: Statistical analysis was conducted using Fisher exact test, Mann-Whitney U test with Bonferroni correction for univariate comparison, and modified Poisson regression for comparison of PON and POV prophylactic efficacy for multivariate analyses. P values <.05 were considered statistically significant. RESULTS: Our study included 218 participants. There were no significant differences in covariates between groups D (n = 111), G (n = 52), and DG (n = 55). No significant difference in PON incidence was observed between groups. However, POV incidence was significantly lower in group DG than group D (relative risk, 0.21; 95% confidence interval, 0.05 to 0.86; P = .03). No significant difference in complication incidence was observed between groups. CONCLUSIONS AND RELEVANCE: Granisetron was as effective as droperidol for PONV management, while droperidol combined with granisetron was more effective than isolated droperidol for POV management. As compared to the use of each drug separately, their combination was considered safe, with no increase in complication rates.

Nutritional counseling for patients with incurable cancer: Systematic review and meta-analysis.

BACKGROUND & AIMS: This systematic review aims to determine whether nutritional counseling by registered dietitians and/or nutritional specialists is recommended for adult patients with incurable advanced or recurrent cancer who are refractory to or intolerant of anticancer therapy. METHODS: This systematic review analyzed randomized controlled trials (RCTs) of nutritional counseling in cancer patients older than 18 years, primarily those with stage 4 cancer. Nutrition counseling was performed by registered dietitians and/or nutritional specialists using any method, including group sessions, telephone consultations, written materials, and web-based approaches. We searched the Medline (PubMed), Medline (OVID), EMBASE (OVID), CENTRAL, Emcare, and Web of Science Core Collection databases for articles published from 1981 to 2020. Two independent authors assessed the risk of bias used the Cochrane Risk of Bias 2 tool. Meta-analysis was performed for results and outcomes that allowed quantitative integration. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (ID: CRD42021288476) and registered in 2021. RESULTS: The search yielded 2376 studies, of which 7 assessed 924 patients with cancer aged 24-95 years. Our primary outcome of quality of life (QoL) was reported in 6 studies, 2 of which showed improvement with nutritional counseling. Our other primary outcome of physical symptoms was reported in two studies, one of which showed improvement with nutritional counseling. Quantitative integration of both QoL and physical symptoms was difficult. A meta-analysis of energy and protein intake and body weight was performed for secondary outcomes. Results showed that nutrition counseling increased energy and protein intake, but total certainty of evidence (CE) was low. Bodyweight was not improved by nutrition counseling. CONCLUSIONS: Nutrition counseling is shown to improve energy and protein intake in patients with incurable cancer. Although neither nutrient intake can be strongly recommended because of low CE, nutrition counseling is a noninvasive treatment strategy that should be introduced early for nutrition intervention for patients with cancer. This review did not find sufficient evidence for the effect of nutrition counseling on QoL, a patient-reported outcome. Overall, low-quality and limited evidence was identified regarding the impact of nutrition counseling for patients with cancer, and further research is needed.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016).

Background and Purpose: The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 in Japanese. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. Methods: Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ), and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (>66.6%) majority vote of each of the 19 committee members. Results: A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for 5 CQs. Conclusions: Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.

[Investigation of the outcomes and complications in right thoracotomy approach for mitral valve reoperation].

BACKGROUND: Right thoracotomy is an alternative surgical technique for mitral valve reoperation. The purpose of this study is to determine whether right thoracotomy for mitral valve reoperation affects its perioperative outcomes and complications. METHODS: We investigated the perioperative events in consecutive mitral valve reoperations between January 2006 and November 2009. Demographic, intraoperative and postoperative data were collected and analyzed retrospectively. RESULTS: Five right thoracotomy cases and 22 repeated sternotomy cases were included. Thoracotomy group needed more platelet transfusion (median, 20 units in thoracotomy; 10 units in sternotomy; P=0.047). We had a higher frequency of adrenaline administration (60% in thoracotomy; 4.6% in sternotomy; P=0.005) and needed more doses of dobutamine in thoracotomy group (median, 16.0 microg x kg(-1) x min(-1) in thoracotomy ; 7.5 microg x kg(-1) x min(-1) in sternotomy; P=0.037) to wean them from cardiopulmonary bypass. Right thoracotomy did not reduce cardiopulmonary bypass time (median, 265 min in thoracotomy ; 199 min in sternotomy; P=0.126). We experienced two serious complications requiring reoperation in thoracotomy group, but diagnosed them with intraoperative transesophageal echocardiography. CONCLUSIONS: When we choose right thoracotomy for mitral valve reoperation, we should prepare more blood products and inotropic agents and should evaluate cardiac function by using intraoperative transesophageal echocardiography.

[Remifentanil prevents hyperglycemia and reduces insulin use during cardiopulmonary bypass in adult cardiac surgery].

BACKGROUND: Remifentanil may be beneficial in patients undergoing cardiac surgery, by attenuating the neurohumoral stress response to surgical stimulation and inflammation evoked by cardiopulmonary bypass (CPB). METHODS: We retrospectively examined blood glucose monitored every 30 minutes during CPB and insulin dose in patients during CPB under remifentanil anesthesia (remifentanil group) and those under low dose fentanyl anesthesia (fentanyl group) in adult cardiac surgery. Furthermore we also investigated incidence of atrial fibrillation within 72 hours after surgery in both groups. RESULTS: There were 35 patients in remifentanil group and 22 patients in fentanyl group. Although blood glucose at the beginning and the end of CPB in both groups were not different, remifentanil group showed lower maximum blood glucose (median 172 mg x dl(-1), interquatile range 156-205 mg x dl(-1)) during CPB than in fentanyl group (197 mg x dl(-1), 176-219 mg x dl(-1); P = 0.009). Significantly less insulin was administered during CPB in remifentanil group than in fentanyl group. Incidence of postoperative atrial fibrillation was similar between the groups. CONCLUSIONS: Maximum blood glucose was lower and less insulin was administered during CPB in remifentanil group. These data may suggest that remifentanil reduce stress response to surgical stimulation in cardiac surgery.

[Anesthesia for living-donor liver transplantation in a patient with adult polycystic liver disease].

Anesthesia for living-donor liver transplantation (LDLT) was performed for two patients with adult polycystic liver disease (APLD). APLD is characterized by gradual cystic transformation of both lobes of the liver. Abdominal enlargement, poor appetite, abdominal pain, infection of liver cysts and portal hypertension are symptoms of this disease. Liver transplantation is indicated as the final therapy. Our two patients had very large livers (7400 g and 9500 g). The second patient had suffered renal failure due to a polycystic kidney so that continuous hemodiafiltration had to be performed after surgery. In both cases, sudden hypotension frequently occurred during manipulation of the enlarged liver. In the first case, sudden massive bleeding occurred as a result of laceration of the middle and left hepatic vein when the liver was dropped from the surgeon's hand. In both cases, the position of endotracheal tube became 2 cm shallower after surgery probably because of the shift in the position of the mediastinum after elimination of abdominal compression caused by the enlarged liver. One patient was discharged 39 days and the other 115 days after surgery. Anesthesiologists should pay special attention to the features reported here during LDLT for patients with APLD.
