How Do Older Patients with End-Stage Osteoarthritis of the Hip Eat Prior to Hip Replacement? A Preliminary Snapshot That Highlights a Poor Diet.

Diet quantity and quality in older adults is critical for the proper functioning of the musculoskeletal system. In view of hip surgery, old patients should consume 1.2-1.5 g of proteins and 27-30 kcal per kilo of body weight daily, and adhere to healthy eating habits. In this analytical study, we studied diet quantity and quality in relation to the clinical chemistry and functional status of 57 older adults undergoing elective hip replacement. Nine in ten patients did not meet suggested protein and energy intakes and only one in ten patients exhibited high adherence to the Mediterranean diet. Legume consumption adjusted for sex, age, body mass index, and health status successfully forecasted haemoglobin levels (p < 0.05), and patients regularly consuming olive oil reported minor hip disability compared to those using it less frequently (p < 0.05). Patients who reported daily ingestion of <1 serving of meat versus those consuming >1.5 servings had greater cumulative comorbidity (p < 0.05), with meat consumption independently predicting walking ability, mobility, and balance in the fully adjusted model (p < 0.01). In conclusion, our patients seem to eat poorly. There is room for improvement in pre-operative pathways to make older adults eat better, but there is a need to plan an interventional study to fully understand the cause-effect of a dietary pattern or specific food in enhancing recovery after surgery.

Risk Factors and Outcomes of Protein-Calorie Malnutrition in Chronic Heart Failure Patients Undergoing Elective Cardiac Surgery.

INTRODUCTION: Chronic heart failure (CHF) patients are often malnourished. Our aim was to determine the effect of protein-calorie malnutrition (PCM) on in-hospital outcomes in CHF patients following elective cardiac surgery and to identify risk factors for PCM in this patient population. METHODS: A retrospective analysis of the National Inpatient Sample (NIS) database was conducted from 2016 to 2018. In-hospital outcomes in adult patients with CHF undergoing elective coronary artery bypass graft (CABG) with cardiopulmonary bypass-assist or cardiac valve replacement surgeries were analyzed. Propensity-score matching was used to match CHF patients with and without PCM and followed by logistic regression analysis. A multivariate logistic regression model was used to identify the risk factors associated with PCM in this population. RESULTS: In total 25,940 CHF patients were identified, of which 6,271 underwent elective CABG and 19,669 underwent valve replacement surgeries. The prevalence of PCM in CHF patients undergoing CABG and valve replacement was 3.9% and 2.9%, respectively. CHF patients with PCM had significantly higher risk of in-hospital mortality, post-operative cardiac and gastrointestinal complications compared to CHF patients without PCM. The mean hospital length of stay was twice as high in the PCM group (mean days: 18.6 vs 9.9). Female gender, Black race (vs White race), a high Charlson Comorbidity Index, Medicare/Medicaid insurance status (vs private insurance), and CHF (systolic and combined systolic and diastolic) were independently associated with significantly higher risk of PCM diagnosis. CONCLUSIONS: CHF patients with PCM who undergo elective CABG or valve replacement surgeries are at a significantly higher risk of mortality, post-operative cardiac and gastrointestinal complications, and increased duration of hospital stay compared to those without PCM. Future prospective studies should assess the CHF patients who are at a higher risk of PCM and whether correcting pre-operative nutrition in this surgical population can improve outcomes following cardiac surgery.

Effectiveness of Ready-to-Use Therapeutic Food Among Children With Protein-Calorie Malnutrition.

Background Malnutrition develops when there is an inadequacy of one or more than one macronutrient for optimum body functioning. This study was designed to determine the effectiveness of ready-to-use therapeutic food (RUTF) in children with protein-calorie malnutrition (PCM) in terms of weight gain and mid-upper arm circumference (MUAC) improvement. Methodology This prospective observational study was done at The Department of Pediatrics, National Institute of Child Health, Karachi, Pakistan from 1st January 2021 to 31st December 2021. A total of 159 children of either gender between six and 59 months of age and diagnosed with PCM were included. All children participating in the study were asked to come back for a follow-up every two weeks until they are 12 weeks old. Outcomes were measured in terms of comparison of weight gain and MUAC at baseline and after 12 weeks of RUTF. Results Of the 159 children, 94 (59.1%) were female. The mean age was 16.8±9.2 months, and 88 (55.3%) children were aged between six to 12 months. The mean body weight was 6.8±9.7 kg. The mean MUAC was calculated to be 116±9.1 mm. There were 121 (76.1%) children who had severe acute malnutrition. One hundred and thirty-one children completed the planned 12-week of follow-up using RUTF in this study, so they were included in the final analysis. Body weight increased significantly from baseline to 12-weeks after RUTF (6.8±1.7 kg vs. 7.6±1.2kg, p<0.0001). Likewise, MUAC also increased from baseline to 12 weeks after RUTF (116.0±9.1 mm vs. 127.2±8.2 mm, p<0.0001). Conclusion The RUTF was found to significantly improve weight gain and MUAC among children aged between six to 60 months with PCM during a period of 12-weeks. Early diagnosis and timely intervention can improve outcomes among children with PCM. Community-based interventions can be aimed to improve the nutritional status of children in a developing country like Pakistan.

Malnutrition risk and severity: Impact on patient outcomes and financial hospital reimbursement in a tertiary teaching hospital.

BACKGROUND & AIMS: Despite its negative impact on patients and health care expenditures, malnutrition remains an under-recognized problem in hospitals. The objectives were thus: 1) to study the prevalence of malnutrition risk, protein-calorie malnutrition and cachexia in a Belgian tertiary care hospital, 2) to evaluate the impact thereof on patient outcomes, and 3) to evaluate the impact of optimizing malnutrition screening, diagnosing, registration and coding on hospital reimbursement. METHODS: Data was included from all multi-day admissions between January 1, 2017 and December 31, 2019. The NRS2002 was used as screening tool. Patient outcomes were modeled using (generalized) linear mixed models, with pathology and severity of illness as random effects. The financial impact of the screening, diagnosing and registration process was evaluated comparing net revenues related to a malnutrition diagnosis in the year before (2017) and the year after (2019) the optimization process. RESULTS: 55,345 patients were evaluated for malnutrition risk at admission of whom 23.6% are considered malnourished or at risk for malnutrition, 0.6% have cachexia and 4.6% protein-calorie malnutrition. Overall length of stay is 2.2 days (p < 0.001) longer in the at-risk population, and 6.2 and 5.0 days longer in patients with cachexia and protein-calorie malnutrition as compared to patients not at risk. Odds ratio for in-hospital mortality is 2.9 (p < 0.001) for the at-risk patients and 3.0 (p < 0.001) for patients with cachexia. Optimization of dietetic workflow and registration, specifying malnutrition severity and facilitating malnutrition coding can increase hospital reimbursement, with approximately 0.4% of all justified beds. CONCLUSIONS: Malnutrition still affects both patients and health care finances. Patients at risk for, or having malnutrition at admission have worse outcomes than those without. Importantly, hospital reimbursement for these patients can effectively be increased by implementing an automated nutritional screening and diagnosing protocol with optimized dietetic registration and enhanced nutritional coding.

Tackling Protein-Calorie Malnutrition during World Crises.

Undernutrition is still highly prevalent in developing countries and leads to a multitude of problems as it weakens the immune system, which leads to increased risk of infections and diet-related diseases. COVID-19 has worsened the existing situation and has resulted in unprecedented health, social, and economic disruptions across the world. Before COVID-19, about 54% children under 5 years were moderately or seriously malnourished, and after the COVID-19 pandemic, early estimates suggest that an additional 2.6 million children were stunted; 9.3 million were wasted, with an addition of 2.1 million maternal anemia cases; 168,000 child deaths; and USD 29.7 billion in productivity losses. This review is mainly focused on the health and nutrition sectors and highlights the impact of COVID-19 on malnutrition, food system and industry, and it also discusses the various measures implemented across the world to cater the burden of maternal and child malnutrition. Movement restrictions and lockdowns within and across the countries/borders have imposed an unprecedented stress and shock on the food supply chain, affecting harvest, food processing, supply, logistics, food demand, shortages, and cost. Many countries have implemented interventions such as cash transfers, food ration distribution, insurance plans, utility subsidy, and tax exemptions to assist the population to cope with the financial and health issues caused due to the outbreak. Other than these measures, evidence recommends some essential direct and indirect interventions which could help in reducing malnutrition during COVID-19. The COVID-19 pandemic has re-demonstrated the connection between food systems, nutrition, health, and prosperity and the need for a more holistic approach.

Thymic Dysfunction and Atrophy in COVID-19 Disease Complicated by Inflammation, Malnutrition and Cachexia.

Background: The current COVID-19 pandemic has put millions of people, especially children at risk of protein-energy malnutrition (PEM) by pushing them into poverty and disrupting the global food supply chain. The thymus is severely affected by nutritional deficiencies and is known as a barometer of malnutrition. Aim: The present commentary provides a novel perspective on the role of malnutrition-induced thymic dysfunction, involution and atrophy on the risk and severity of disease in children during the COVID-19 pandemic. Methods: A review of pertinent indexed literature including studies examining the effects of malnutrition on the thymus and immune dysfunction in COVID-19. Results: Protein-energy malnutrition and micronutrient deficiencies of zinc, iron and vitamin A are known to promote thymic dysfunction and thymocyte loss in children. Malnutrition- and infection-induced thymic atrophy and immune dysfunction may increase the risk of first, progression of COVID-19 disease to more severe forms including development of multisystem inflammatory syndrome in children (MIS-C); second, slow the recovery from COVID-19 disease; and third, increase the risk of other infections. Furthermore, malnourished children may be at increased risk of contracting SARS-CoV-2 infection due to socioeconomic conditions that promote viral transmission amongst contacts and create barriers to vaccination. Conclusion: National governments and international organizations including WHO, World Food Program, and UNICEF should institute measures to ensure provision of food and micronutrients for children at risk in order to limit the health impact of the ongoing COVID-19 pandemic.

The clinical impact of malnutrition on the postoperative outcomes of patients undergoing gastrectomy for gastric cancer: Propensity score matched analysis of 2011-2017 hospital database.

BACKGROUND & AIMS: Malnutrition is a prominent feature of gastric cancer patients who suffer from gastric outlet obstruction, impaired peristalsis, and cancer-mediated disruptions in metabolic hemostasis. In this study, we systematically evaluate the impact of malnutrition on the postoperative outcome of patients with gastric cancer undergoing gastrectomy. METHODS: 2011-2017 National Inpatient Sample was used to isolate patients with gastric cancer who underwent gastrectomy, who were stratified using malnutrition. The malnutrition-present cohort was matched to the malnutrition-absent controls using 1:1 propensity score-matching analysis, and compared to the following endpoints: mortality, length of stay (LOS), hospitalization costs, and postoperative complications. RESULTS: 5309 were identified to have undergone gastric resection procedure for gastric cancer, from which there were 1044 with malnutrition and 1044 matched controls. Malnourished patients had higher mortality (6.80 vs 3.83% p = 0.003, OR 1.83 95% CI 1.23-2.73), LOS (17.2 vs 11.4 d p < 0.001), costs ($197,702 vs $124,133 p < 0.001), and were more often discharged to rehabilitation facilities. Malnourished patients had higher rates of wound complications (3.64 vs 1.25% p < 0.001, OR 3.00 95% CI 1.59-5.66), infection (6.90 vs 3.26% p < 0.001, OR 2.20 95% CI 1.45-3.34), and respiratory failure (6.80 vs 3.64% p = 0.002, OR 1.93 95% CI 1.29-2.89). In multivariate analysis, malnourished patients had higher rates of mortality (p = 0.002, aOR 1.87 95% CI 1.25-2.80), length of stay (p < 0.001, aOR 1.52 95% CI 1.48-1.55), costs (p < 0.001, aOR 1.61 95% CI 1.61-1.61) despite controlling for non-matched hospital variables. CONCLUSION: In this propensity score matched analysis, malnutrition is associated with increased postoperative mortality, LOS, and hospitalization costs in patients with gastric cancer undergoing gastric resection surgery.

Severe Protein-Calorie Malnutrition-Associated Hepatic Steatosis in a Woman Who Had Roux-en-Y Gastric Bypass for Morbid Obesity Thirteen Years Ago.

Hepatic steatosis is common in everyday liver pathology practice. There are many etiologies leading to hepatic steatosis. These etiologies include metabolic syndrome, alcohol, medications, monogenetic disease, infectious diseases, and malnutrition. Correct diagnosis of underlying etiology through clinicopathological correlation is key to adequate treatment and optimal outcome for the patient. In this case report, we describe severe protein-calorie malnutrition as an etiology for hepatic steatosis in a middle-aged woman who presented with lethargy, low body mass index (15.8 kg/m2), abdominal distention and bilateral lower extremity edema, hyperammonemia, and hypoalbuminemia, 13 years after Roux-en-Y gastric bypass for morbid obesity. Laboratory tests revealed hyperammonemia, hypoalbuminemia, and low ceruloplasmin levels. Hemodynamic measurement demonstrated high hepatic venous pressure gradient of 12 mm Hg. Transjugular liver biopsy showed moderate macrovesicular steatosis, mild siderosis, and abundant lipofuscin but no evidence of fibrosis, cirrhosis, or steatohepatitis. This patient was treated with lactulose and enteral feeding, however, the patient died of progressive liver failure 3 weeks after admission. We also review relevant literature to help diagnose protein-calorie malnutrition (kwashiorkor) and hepatic steatosis as a possible late complication of Roux-en-Y gastric bypass. In patients with hepatic steatosis, encephalopathy, hyperammonemia and portal hypertension, malnutrition should be considered as an etiology and diagnosed with a synthesis of clinical, pathological, and laboratory information. Kwashiorkor is a severe disease and should be treated promptly as it may be fatal as in our case.

The clinical impact of malnutrition on the postoperative outcomes of patients undergoing colorectal resection surgery for colon or rectal cancer: Propensity score matched analysis of 2011-2017 US hospitals.

BACKGROUND & AIMS: Malnutrition can be prevalently found in patients with significant-to-advanced colorectal cancer, who potential require colorectal resection procedures; to accurately describe the postoperative risks, we used a propensity-score matched comparison of national database to analyze the effects of malnutrition on post-colectomy outcomes. METHODS: 2011-2017 National inpatient Sample was used to isolate inpatient ceases of colorectal resection procedures, which were stratified using malnutrition into malnutrition-present cohort and malnutrition-absent controls; the controls were propensity-score matched with the study cohort using 1:1 ratio and compared to the following endpoints: mortality, length of stay, costs, postoperative complications. RESULTS: After matching, there were 11357 with and without malnutrition who underwent colorectal resection surgery; in comparison, malnourished patients had higher rates of in-hospital mortality (6.14 vs 3.22% p < 0.001, OR 1.96 95%CI 1.73-2.23), length of stay (15.4 vs 9.61d p < 0.001), costs ($163, 962 vs $102,709 p < 0.001), and were more likely to be discharged to non-routine discharges, including short term hospitals, skilled nursing facilities, and home healthcare. In terms of complications, malnourished patients had higher bleeding (2.87 vs 1.68% p < 0.001, OR 1.73 95%CI 1.44-2.07), wound complications (4.31 vs 1.34% p < 0.001, OR 3.32 95%CI 2.76-3.99), infection (6 vs 2.62% p < 0.001, OR 2.38 95%CI 2.07-2.73), and postoperative respiratory failure (7.27 vs 3.37% p < 0.001, OR 2.25 95%CI 1.99-2.54). CONCLUSION: This study demonstrates the presence of malnutrition to be associated with adverse postoperative outcomes including mortality and complications in patients undergoing colorectal resection surgery for colon cancer.

The Hardship of Recovering a Patient from Liver Failure after One Anastomosis Gastric Bypass.

BACKGROUND: The one anastomosis gastric bypass (OAGB) was first described in 2001 as a safe and effective procedure that meets the criteria for the "ideal" weight loss operation. However, revisions for malnutrition and liver failure were reported. CASE REPORT: We report a patient who was transferred to our institution with protein calorie malnutrition and liver failure after undergoing OAGB. METHODS: A 42-year-old morbidly obese female patient underwent a laparoscopic sleeve gastrectomy (LSG) in 2012 followed by conversion to OAGB in 2018 for weight regain at another institution. Nine months after conversion, she was transferred to our institution with dehydration, vomiting, dysphagia, generalized edema, and steatorrhea (7 times/day). She had become wheelchair bound. On examination, there was gross edema, protein-calorie malnutrition, dermatitis, and muscle wasting. She had anemia (8 g/dl) reference range (11.5-15.5 g/dl), bilirubin (1.8 mg/dl) (0.2-1.2 mg/dl), hypoalbuminemia (1.4 g/dl) (3.5-5 g/dl), and elevated international normalized ratio (INR). The patient was admitted to the hospital and was started on total parenteral nutrition (TPN), with thiamine, vitamins, iron injections, and trace mineral replacement. Her course was complicated by multiple episodes of line sepsis and bacteremia. After 6 weeks, we succeeded in raising her albumin to 2.9 g/dl and proceeded with surgery. TECHNIQUE: Laparoscopic exploration started with identifying the anatomy and measuring the biliopancreatic limb (BPL = 430 cm) and the common channel (CC = 380 cm). First, we restored the continuity of the small bowel. Then the long gastric pouch was trimmed. Finally, the patient was converted to a Roux-en-Y gastric bypass (RYGB) with a 30 cm BP limb and 70 cm Roux limb. The patient had an uneventful recovery and was discharged home on the fourth postoperative day. At 3 months of follow-up, her symptoms resolved, her laboratory work up normalized, and she regained mobility. CONCLUSION: Malnutrition and liver failure after OAGB are not uncommon. It is encountered with configurations of longer BP limb. BPL length of 150 to 200 cm seems to reduce such complications. Preoperative nutritional optimization is key. Conversion to a proximal RYGB is a safe and feasible approach.

Beta Thalassemia Major with Gaucher's Disease: A Rare Entity.

Thalassemia is a genetic disorder due to deletion or mutation in the gene for alpha or beta chain of hemoglobin. Gaucher's disease (GD) is characterized by a deficiency of a lysosomal enzyme, glucocerebrosidase which occurs due to mutations in the GBA1 gene on chromosome 1. Thalassemia and GD have overlapping clinical manifestations and present with features such as anemia, hepatosplenomegaly, and skeletal involvement. This creates a diagnostic conundrum for physicians. We present a case of an 11-month-old female who presented with fever, increasing paleness, and labored breathing. She had a recent history of uncross-matched transfusion. The child showed signs of anemic failure. Physical exam findings strongly pointed towards hemolytic anemia due to thalassemia major. Genetic analysis confirmed homozygosity in Fr 8-9 mutation confirming beta thalassemia major. Bicytopenia along with visceromegaly indicated malaria or storage diseases. Enzyme analysis revealed low levels of beta-glucocerebrosidase with normal acid sphingomyelinase levels confirming GD. In our case, we report the association of beta thalassemia major with GD which is a rare entity. The report highlights the need for an independent assessment of disorders that have similar presentations to avoid missing an associated disorder.

From menu to mouth: the decay pathway of nutrient intake from planned menu to consumed and characteristics of residents in an aged care facility with greater nutrient decay rates: a cross-sectional study.

OBJECTIVES: To observe the cascade of nutrient loss from meals planned to those provided and subsequently consumed by older people in residential care. A secondary aim was to determine the characteristics of residents with higher nutrient loss resulting in lower intake of key nutrients. DESIGN: A single-centre cross-sectional study. SETTING: An aged residential care facility in Christchurch, New Zealand. PARTICIPANTS: All low and high level of care residents except those who are end of life, enterally fed or on short-term stay were invited to participate in the study. 54 of 60 selected residents who consumed all three main meals (breakfast, lunch and dinner) for three non-consecutive days were included in the analyses. MAIN OUTCOME MEASURES: Nutrient contents of planned menu; nutrient contents of meals served and consumed using modified 3-day diet records; and percentage of planned nutrients served and consumed. RESULTS: Vitamins C, B12 and folate had the greatest total decay rates of 50% or more from that planned to be consumed to what was actually consumed, while unsaturated fats, beta carotene, iodine and zinc had the lowest decay rates of 25% or less. Male participants and lower care level residents consumed significantly more nutrients, compared with female participants and those receiving higher level care. Increased age, female gender, higher level of care, smaller meal size, pureed diet and lower body mass index were associated with larger decay rates and lower nutrient intakes. CONCLUSIONS: Not all planned and served food and beverages are consumed, contributing to potential multiple nutrient deficiencies including energy and protein in the majority of aged-care residents. As a consequence, some nutrients may need to be oversupplied if consumption is to match planned intakes.

Nutritional and Micronutrient Care of Bariatric Surgery Patients: Current Evidence Update.

PURPOSE OF REVIEW: The continued success of bariatric surgery to treat obesity and obesity-associated metabolic conditions creates a need for a strong understanding of clinical nutrition both before and after these procedures. RECENT FINDINGS: Surgically induced alteration of gastrointestinal physiology can affect the nutrition of individuals, especially among those who have undergone malabsorptive procedures. While uncommon, a subset of patients may develop protein-calorie malnutrition. In these cases, nutrition support should be tailored to the severity of malnutrition. Among all patients who undergo bariatric surgery, high rates of micronutrient deficiencies have been observed. To mitigate these deficiencies, empiric supplementation with multivitamins, calcium citrate, and vitamin D is generally recommended. Periodic surveillance should be performed for commonly deficient micronutrients, including thiamin (B1), folate (B9), cobalamin (B12), iron, and vitamin D. Following Roux-en-Y gastric bypass, serum levels of copper and zinc should also be monitored. In addition, lipid-soluble vitamins should be monitored following biliopancreatic diversion with/without duodenal switch.

Hepatic complications of bariatric surgery : the reverse side of the coin.

BACKGROUND: Even if the jejunoileal bypass has been definitely abandoned due to the high rate of hepatic complications, cases of liver injury after the new bariatric procedures are still reported. We aimed to review the available literature concerning liver damage associated with the older and newer types of bariatric surgeries. METHODS: An extensive literature search of MEDLINE was performed using different combinations of the following terms: "bariatric surgery OR biliopancreatic diversion OR jejunoileal bypass OR roux-en-y gastric bypass OR vertical banded gastroplasty OR laparoscopic adjustable gastric banding" AND "hepatic/liver damage OR hepatic/liver impairment OR hepatic/liver failure". RESULTS: Although weight loss after bariatric surgery frequently induces an improvement of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis, and even the regression of hepatic fibrosis, bariatric procedures have been also associated with cases of acute liver failure or of chronic liver disease evolving until cirrhosis. After the jejunoileal bypass has been definitely abandoned, most of the recently described cases concern biliopancreatic diversion with/without duodenal switch, but liver damage has been reported after almost all types of bariatric surgeries. Protein-calorie malnutrition, bacterial overgrowth, lipotoxicity and genetic background are likely to play a central role in the physiopathology of hepatic injury. CONCLUSIONS: Understanding the inner mechanisms underlying acute or chronic liver injury after bariatric surgery can help in the prevention, early recognition and treatment of these rare but concrete cases.

Fidelity in Animal Modeling: Prerequisite for a Mechanistic Research Front Relevant to the Inflammatory Incompetence of Acute Pediatric Malnutrition.

Inflammatory incompetence is characteristic of acute pediatric protein-energy malnutrition, but its underlying mechanisms remain obscure. Perhaps substantially because the research front lacks the driving force of a scholarly unifying hypothesis, it is adrift and research activity is declining. A body of animal-based research points to a unifying paradigm, the Tolerance Model, with some potential to offer coherence and a mechanistic impetus to the field. However, reasonable skepticism prevails regarding the relevance of animal models of acute pediatric malnutrition; consequently, the fundamental contributions of the animal-based component of this research front are largely overlooked. Design-related modifications to improve the relevance of animal modeling in this research front include, most notably, prioritizing essential features of pediatric malnutrition pathology rather than dietary minutiae specific to infants and children, selecting windows of experimental animal development that correspond to targeted stages of pediatric immunological ontogeny, and controlling for ontogeny-related confounders. In addition, important opportunities are presented by newer tools including the immunologically humanized mouse and outbred stocks exhibiting a magnitude of genetic heterogeneity comparable to that of human populations. Sound animal modeling is within our grasp to stimulate and support a mechanistic research front relevant to the immunological problems that accompany acute pediatric malnutrition.

Tolerance of early oral feeding in patients subjected to total laryngectomy.

BACKGROUND: The purpose of this study was to assess the tolerance of early oral feeding after total laryngectomy. METHOD: A randomized multicenter study was conducted that included 89 individuals subjected to total laryngectomy. The participants were allocated to 2 groups: early (n = 44), early oral feeding; and late (n = 45), late oral feeding. The participants in the early group were assessed as to acceptance of oral feeding, and their food intake was quantified. RESULTS: In the early group, the total energy expenditure and protein needs were not met through oral feeding alone at any time during the first 7 postoperative days. The times to attain 25% and 50% of the total energy expenditure and protein needs by oral feeding after surgery were 4 and 7 days, respectively. CONCLUSION: The patients subjected to early oral feeding failed to meet their caloric and protein needs through that route alone during the first 4 postoperative days and required complementary nutrition through another route. © 2015 Wiley Periodicals, Inc.

Management of Excessive Weight Loss Following Laparoscopic Roux-en-Y Gastric Bypass: Clinical Algorithm and Surgical Techniques.

BACKGROUND: There are no clinical guidelines or published studies addressing excessive weight loss and protein calorie malnutrition following a standard Roux-en-Y gastric bypass (RYGB) to guide nutritional management and treatment strategies. This study demonstrates the presentation, clinical algorithm, surgical technique, and outcomes of patients afflicted and successfully treated with excessive weight loss following a standard RYGB. METHODS: Three patients were successfully reversed to normal anatomy after evaluation, management, and treatment by multidisciplinary team. Lowest BMI (kg/m(2)) was 18.9, 17.9, and 14.2, respectively. RESULTS: Twelve-month post-operative BMI (kg/m(2)) was 28.9, 22.8, and 26.1, respectively. Lowest weight (lbs) was 117, 128, and 79, respectively. Twelve-month post-operative weight (lbs) was 179, 161, and 145, respectively. Pre-reversal gastrostomy tube was inserted into the remnant stomach to demonstrate weight gain and improve nutritional status prior to reversal to original anatomy. CONCLUSION: We propose a practical clinical algorithm for the work-up and management of patients with excessive weight loss and protein calorie malnutrition after standard RYGB including reversal to normal anatomy.

A Case of Pneumocystis jirovecii Pneumonia in a Severely Malnourished, HIV-Negative Patient: A Role for Malnutrition in Opportunistic Infections?

Malnutrition increases the risk of infections in patients receiving medical and surgical procedures, but it is not clear whether it may facilitate also the development of opportunistic infections in human immunodeficiency virus (HIV)-negative patients not receiving immunosuppressive therapies. Here we report the first case of a non-HIV, severely malnourished woman who developed Pneumocystis jirovecii pneumonia. This report highlights the clinical relevance of malnutrition as a determinant of immune suppression, which in turn may also favor opportunistic infections. Therefore, routine nutrition screening and assessment, as well as timely start of nutrition therapy, should be prioritized in daily clinical practice to reduce complications and improve outcome.

Analysis of Current Use of Early Parenteral Nutrition and Clinical Significance of Non-protein Calorie: Nitrogen in Surgical Critically Ill Patients

PUROPOSE: Surgical critically ill patients require adequate nutrition support and the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) guidelines recommend low non-protein calorie:nitrogen ratio (NPC:N ratio, 70~100) for critically ill pateints. In this study, we assess the current use of early parenteral nutrition of surgical critically ill patients and analyze the clinical significance of NPC:N. METHODS: This is a retrospective study of critically ill adult patients who remained in the intensive care unit (ICU) for over 3 days and could not receive enteral nutrition for the first 7 days. Data on parenteral intake of patients were collected from electronic medical records. Association of NPC:N scores with clinical outcome (length of ICU stay, length; of hospital stay, duration of ventilation, and mortality) were analyzed using Pearson correlation and multiple regression. RESULTS: The study included 72 cases, average parenteral calorie intake was 14.6 kcal/kg/day and protein intake was 0.5 g/kg/day. We assessed the NPC:N scores to determine the patients' NPC:N for the first 7 days in ICU close to the A.S.P.E.N guidelines. NPC:N scores showed weak negative correlation with length of hospital stay and duration of mechanical ventilation (r=-0.259, P=0.028; r=-0.495, P=0.001). Multiple regression adjusted with APACHE (Acute Physiology and Chronic Health Evaluation) II score, age, and body mass index showed correlation of higher NPC:N score with decreased length of hospital stay and shorter duration of ventilation (P=0.0001, P=0.035, respectively). However, length of ICU stay and mortality within 60 days showed no significant correlation with NPC:N scores. CONCLUSION: Parenteral calories and protein intakes of critically ill patients in ICU were lower in comparison to A.S.P.E.N. recommendation in this study. Low NPC:N scores might be related to shorter length of hospital stay, duration of mechanical ventilation. Consultation of a nutritional support team could have a positive effect in providing appropriate nutrition support.
