Changes in Food Preferences Before and After Intragastric Balloon Placement. Obes Surg 2024; 34:2091-2100.

Abstract
BACKGROUNDS In recent years, numerous studies have tried to decode the way bariatric surgery works toward weight reduction by the use of food preference questionnaires. The intragastric balloon has gained popularity, mainly due to its limited invasiveness, in patients with obesity not fulfilling criteria for bariatric surgery. However, there is no study assessing the changes in food preferences [FP]. We decided to analyze the FP of individuals prior to intragastric balloon insertion and following its removal, on the strict condition that participants must complete the 6-month treatment period and attend at least 4 of the 7 follow-up interviews. METHODS Patients were asked to rate the frequency of consumption of 63 food items before balloon insertion, at monthly intervals and after balloon removal. The food categories were protein, carbohydrates, fruit and vegetables, and sweets and fats. RESULTS The questionnaires of 320 participants were analyzed. A reduced frequency in consumption of meat and meat products, high-fat, and high-carbohydrate/sugary products and an increase in raw vegetables and fruit was found in all individuals. CONCLUSION The intragastric balloon seems to exert analogically similar mechanisms to bariatric surgery for weight loss, both functioning through alterations in FP. These are dictated by the anatomical re-configuration of the stomach, but mainly by counseling of dieticians and the self-education of the patient after experiencing unpleasant postprandial discomfort.

Abstract
Wound healing is a multi-factorial response to tissue injury, aiming to restore tissue continuity. Numerous recent experimental and clinical studies clearly indicate that probiotics are applied topically to promote the wound-healing process. However, the precise mechanism by which they contribute to healing is not yet clear. Each strain appears to exert a distinctive, even multi-factorial action on different phases of the healing process. Given that a multi-probiotic formula exerts better results than a single strain, the pharmaceutical industry has embarked on a race for the production of a formulation containing a combination of probiotics capable of playing a role in all the phases of the healing process. Hence, the object of this review is to describe what is known to date of the distinctive mechanisms of each of the most studied probiotic strains in order to further facilitate research toward the development of combinations of strains and doses, covering the whole spectrum of healing. Eleven probiotic species have been analyzed, the only criterion of inclusion being a minimum of two published research articles.

World J Gastrointest Surg 2023; 15:940-952. [PMID: 37342839 PMCID: PMC10277955 DOI: 10.4240/wjgs.v15.i5.940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/28/2023] [Accepted: 04/07/2023] [Indexed: 05/26/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Percutaneous endoscopic gastrostomy (PEG) is a well-established, minimally invasive, and easy to perform procedure for nutrition delivery, applied to individuals unable to swallow for various reasons. PEG has a high technical success rate of insertion between 95% and 100% in experienced hands, but varying complication rates ranging from 0.4% to 22.5% of cases.
AIM To discuss the existing evidence of major procedural complications in PEG, mainly focusing on those that could probably have been avoided, had the endoscopist been more experienced, or less self-confident in relation to the basic safety rules for PEG performance.
METHODS After a thorough research of the international literature of a period of more than 30 years of published “case reports” concerning such complications, we critically analyzed only those complications which were considered - after assessment by two experts in PEG performance working separately - to be directly related to a form of malpractice by the endoscopist.
RESULTS Malpractice by the endoscopist were considered cases of: Gastrostomy tubes passed through the colon or though the left lateral liver lobe, bleeding after puncture injury of large vessels of the stomach or the peritoneum, peritonitis after viscera damage, and injuries of the esophagus, spleen, and pancreas.
CONCLUSION For a safe PEG insertion, the overfilling of the stomach and small bowel with air should be avoided, the clinician should check thoroughly for the proper trans-illumination of the light source of the endoscope through the abdominal wall and ensure endoscopically visible imprint of finger palpation on the skin at the center of the site of maximum illumination, and finally, the physician should be more alert with obese patients and those with previous abdominal surgery.

Abstract
The probiotics Lactiplantibacillus plantarum UBLP-40, Lactobacillus rhamnosus UBLR-58 and Bifidobacterium longum UBBL-64 seem to promote wound healing when applied topically. Our aim was to investigate their effect on the mRNA expression of pro-inflammatory, healing and angiogenetic factors during the healing process of a standardized excisional wound model in rats. Rats subjected to six dorsal skin wounds were allocated to Control; L. plantarum; combined formula of L. rhamnosus plus B. longum; L. rhamnosus; and B. longum treatments, applied every two days, along with tissue collection. The pro-inflammatory, wound-healing, and angiogenetic factors of mRNA expression were assessed by qRT-PCR. We found that L. plantarum exerts a strong anti-inflammatory effect in relation to L. rhamnosus-B. longum, given alone or in combination; the combined regime of L. rhamnosus-B. longum, works better, greatly promoting the expression of healing and angiogenic factors than L. plantarum. When separately tested, L. rhamnosus was found to work better than B. longum in promoting the expression of healing factors, while B. longum seems stronger than L. rhamnosus in the expression of angiogenic factors. We, therefore, suggest that an ideal probiotic treatment should definitively contain more than one probiotic strain to speed up all three healing phases.

Abstract
Buried bumper syndrome (BBS) is the situation in which the internal bumper of the gastrostomy tube, due to prolonged compression of the tissues between the external and the internal bumper, migrates from the gastric lumen into the gastric wall or further, into the tract outside the gastric lumen, ending up anywhere between the stomach mucosa and the surface of the skin. This restricts liquid food from entering the stomach, since the internal opening is obstructed by gastric mucosal overgrowth. We performed a comprehensive search of the PubMed literature to retrieve all the case-reports and case-series referring to BBS and its management, after which we focused on the endoscopic techniques for releasing the internal bumper to re-establish the functionality of the tube. From the “push” and the “push and pull T” techniques to the most sophisticated-using high tech instruments, all 10 published techniques have been critically analysed and the pros and cons presented, in an effort to optimize the criteria of choice based on maximum efficacy and safety.

Abstract
This is a post-hoc analysis to assess the effect of anesthesia, surgical trauma, and extracorporeal circuit on endothelial integrity, microvascular permeability, and extracellular fluid balance, as well as on skeletal muscle catabolism, in patients undergoing elective cardiac surgery. We included 127 well-nourished patients undergoing “on-pump” elective cardiac surgery. One day prior to surgery (D0) and again on postoperative day 7 (POD7), body mass index, body composition assessment, hand-grip strength (HGS), and mid-upper arm muscle circumference (MAMC) were measured. Patients were assigned to early recovery (ER) and late recovery (LR) groups, depending on the duration of ICU stay (cut-off 48 hours). The magnitude of change (Δ) in all parameters studied was assessed in ER versus LR groups, regarding (i) epithelial tissue dysfunction (Δ-Extra-Cellular Water percentage (Δ-ECW%), Δ-Phase Angle (Δ-PhA)), (ii) skeletal muscle mass catabolism (Δ-Skeletal muscle mass reduction%, Δ-Hand Grip Strength (Δ-HGS) and Δ-Mid Upper-Arm Muscle Circumference (Δ-MAMC)). Baseline measurements were similar in both groups. A significant difference was observed in all Δ-parameters studied (Δ-ECW%, Δ-PhA and muscle catabolism, Δ-HGS, Δ-MAMC), the worse results being correlated to the LR group. The results raise the issue that patients with early recovery may silently have pathological conditions, continuing even on the day of discharge - further research should be planned.

Abstract
Investigations that focused on the protective role of probiotics against Surgical Site Infections (SSI) in multiple-trauma (MT) patients are generally few, probably due to the complexity of the concept of trauma. We aimed to assess the efficacy of a four-probiotic regime to reduce the incidence of SSI in MT patients, with a brain injury included. MT patients, being intubated and expected to require mechanical ventilation for >10 days, were randomly allocated into placebo (n = 50) or probiotic treatment (n = 53) comprising Lactobacillus acidophilus LA-5 (1.75 × 109 cfu), Lactiplantibacillus plantarum UBLP-40 (0.5 × 109 cfu), Bifidobacterium animalis subsp. lactis BB-12 (1.75 × 109 cfu), and Saccharomycesboulardii Unique-28 (1.5 × 109 cfu) in sachets. All patients received two sachets of placebo or probiotics twice/day for 15 days and were followed-up for 30 days. The operations were classified as neurosurgical, thoracostomies, laparotomies, orthopedics, and others; then, the SSI and the isolated pathogen were registered. A total of 23 (46.0%) and 13 (24.5%) infectious insults in 89 (50 placebo patients) and 88 (53 probiotics-treated) operations (p = 0.022) were recorded, the majority of them relating to osteosynthesis—17 and 8, respectively. The most commonly identified pathogens were Staphylococcus aureus and Acinetobacter baumannii. Our results support published evidence that the prophylactic administration of probiotics in MT patients exerts a positive effect on the incidence of SSI.

Abstract
BACKGROUND This study aims to investigate the probable lesions and injuries induced in the renal tissue after a cardiac arrest. The renal ischemia-reperfusion model in cardiac arrest describes the effects of ischemia in the kidneys, alongside a whole-body ischemia-reperfusion injury. This protocol excludes ischemic conditions caused by surgical vascular manipulation, venous injury or venous congestion. METHODS For the experimental study, 24 swine were subjected to cardiac arrest. Seven minutes later, the cardiopulmonary resuscitation technique was performed for 5 min. Afterwards, advanced life support was provided. The resuscitated swine consisted one group and the non-resuscitated the other. Tissue samples were obtained from both groups for light and electron microscopy evaluation. RESULTS Tissue lesions were observed in the tubules, parallel to destruction of the microvilli, reduction in the basal membrane invaginations, enlarged mitochondria, cellular vacuolization, cellular apoptosis and disorganization. In addition, fusion of the podocytes, destruction of the Bowman's capsule parietal epithelium and abnormal peripheral urinary space was observed. The damage appeared more extensive in the non-resuscitated swine group. CONCLUSIONS Acute kidney injury is not the leading cause of death after cardiac arrest. However, evidence suggests that the kidney damage after a cardiac arrest should be highly considered in the prognosis of the patients' health outcome.

Abstract
Nowadays, there is an increasing knowledge that probiotic bacteria, topically applied, affects skin pathology. The objective of this study is to evaluate the effect on wound healing of locally applied probiotics by calculating the 3-D configuration of a standardized excisional wound. Fifty-two male Wistar rats were randomly allocated into groups: control, PRO1 [L. plantarum] and PRO2 [L. rhamnosus, B. longum]. Six excisional full-thickness wounds were created on each dorsum by an 8-mm circular biopsy punch; probiotics or saline were applied on days 0, 2, 4, 8, 16, photos of the wounds taken and specimens excised for histology [4 rats/group/time-point]. Both probiotic-groups exhibited accelerated healing significantly faster than the control, throughout, PRO2 exhibiting finally the best results [day 16]. However, only on day 2, did PRO1 exhibit the best results [wounded area, borders distance and epitheliazation line]. The results clearly demonstrate that the topical application of probiotics significantly improves the healing process, each strain working differently and more effectively in different healing phases. Thus, a combined formula containing different probiotics to modulate various healing phases is desirable. To this end our research continous.

Abstract
Aim: To establish whether the addition of probiotics to a globally accepted Helicobacter pylori (H. pylori)-eradication scheme may reduce the rates of side effects and increase the eradication rates. Methods. Prospective, randomized, placebo-controlled trial of patients receiving eradication therapy for H. pylori in the eight participating centers. All patients received a 10-day proton pump inhibitor containing non-bismuth quadruple therapeutic regimen for H. pylori eradication (omeprazole 20 mg, amoxycillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg all twice daily orally) and were randomized to receive either probiotics (group A) or placebo (group B). The probiotic used combined four probiotic strains, i.e., Lactobacillus Acidophilus, Lactiplantibacillus plantarum, Bifidobacterium lactis, and Saccharomyces boulardii. Results. Data were analyzed for 329 patients in group A and 335 patients in group B. Fifty six (17.0%) patients in group A and 170 (50.7%) patients in group B reported the occurrence of an H. pylori treatment-associated new symptom or the aggravation of a pre-existing symptom of any severity (p < 0.00001). H. pylori was successfully eradicated in 303 patients in group A (92.0%) and 291 patients in group B (86.8%), (p = 0.028). Conclusion: Adding probiotics to the 10-day concomitant non-bismuth quadruple H. pylori eradication regimen increases the eradication rate and decreases side effects.

Abstract
INTRODUCTION/PURPOSE The accuracy of body mass index (BMI) in detecting obesity in patients treated by intragastric balloon (IGB) remains still speculative. We aimed to determine the discriminatory performance of BMI as an estimate of excess body fat (%BF) in an IGB-treated population. MATERIAL AND METHODS Retrospective analysis of prospectively collected data of 476 patients who completed the 6-month IGB treatment period and were subjected to body composition analysis. We evaluated the relationship between BMI and %BF or lean mass and the diagnostic performance of BMI ≥ 30 kg/m2 for adipose tissue detection, stratified by age (< 40 and ≥ 40 years) and gender. Moreover, we identified anthropometric and body composition parameters serving as predictors of obesity according to %BF-based criteria (> 25% in men or > 35% in women). RESULTS Gender emerged as an effect modifier in the quadratic polynomial relationship between BMI and %BF (R2 = 0.849 for men, R2 = 0.715 for women), while BMI was linearly associated with %BF in both age groups (R2 = 0.435 for men, R2 = 0.474 for women). BMI was strongly correlated with both %BF (r = 0.67) and lean mass (r = - 0.65). The overall area under the ROC curve for BMI ≥ 30 kg/m2 to detect %BF was 0.87 (95%CI 0.85-0.90). A regression model including lean mass, total body water, age, BMI, and female gender explained 0.970 of the variance in %BF. CONCLUSION The discriminatory performance of BMI as an estimate of excess body fat is enhanced by the implementation of gender- and age-specific BMI thresholds for defining obesity, in IGB-treated patients.

Abstract
OBJECTIVE This study aimed to benchmark the prognostic validity of nutritional status, body composition, phase angle, and muscle strength assessment on the basis of morbidity and mortality in the cardiac surgery population. DESIGN Prospective, cohort study. SETTING Tertiary university hospital. PARTICIPANTS Patients undergoing cardiac surgery procedures. INTERVENTIONS Demographic, anthropometric, and clinical data registration, handgrip strength (HGS) measurement, and body composition assessment were performed the day before the scheduled surgery in a cohort of 179 cardiac surgery patients. Body composition parameters and HGS were reassessed on postoperative day seven (POD7). The study endpoints were the hospital length of stay (LOS) and in-hospital mortality. RESULTS Data from a cohort of 179 patients were analyzed. Significant impairment of nutritional status, body composition parameters, and HGS were recorded on POD seven (p < 0.001), which was associated with prolonged hospital LOS (p < 0.05). Postoperative low phase angle (PhA) (odds ratio [OR] 4.366; 95% confidence interval [CI] 1.859-10.255; p = 0.001), reduced fat-free mass index (OR 1.077; 95% CI 1.020-1.137; p = 0.008), and expanded extracellular water (ECW) (OR 1.230; 95% CI 1.080-1.401; p = 0.002) were the most powerful predictors of prolonged hospital LOS, with PhA (hazard ratio [HR] 1.228; 95% CI 1.074-1.403; p = 0.003) and ECW (HR 0.945; 95% CI 0.909-0.982; p = 0.004) serving as predictors of in-hospital mortality. Postoperative PhA, ECW, and total body water presented superior or at least equivalent discrimination of morbidity or mortality to EuroSCORE II. CONCLUSIONS Cardiac surgery patients are at risk of nutritional status deterioration during their hospitalization course, which, in turn, exerts an adverse effect on the outcome. Attenuation of PhA, deterioration of fat-free mass index, and edema development constitute potential surrogates to the prediction of morbidity and mortality.

Abstract
PURPOSE Percutaneous endoscopic gastrostomy [PEG] by the pull-technique is easy and safe to perform through the oral cavity. However, the presence of a cervical esophageal fistula, either due to tumor invasion or simply inflammation and tissue necrosis after previous intervention or radiotherapy, in the anterior cervical region is of crucial importance when passing the endoscope and the PEG catheter from the mouth downwards. METHODS We describe a modification of the standard peroral PEG, which is to insert the endoscope from the cervical esophageal opening instead of the oral cavity, and we support the use of this "stoma" as a way to protect it and avoid possible forceful dilatation/expansion when advancing the endoscope and the gastrostomy catheter through the mouth. RESULTS The performance of PEG through the cervical esophageal opening was applied in 8 cases of esophageal fistula of different primary etiology but where the oro-pharyngeal passage was easily accessible. The procedure was technically successful in all patients, and no bleeding or tearing of the friable esophageal wall was evident. CONCLUSION The use of the esophageal fistula at the anterior cervical region as a route for PEG insertion is a safe and practical alternative, highly to be recommended.

Abstract
BACKGROUND The BioEnterics Intragastric Balloon [BIB] is a reliable, non-invasive technique to manage obesity for subjects who refuse or are unsuitable for bariatric surgery. In a prior study, BIB placed in the antrum [A] was found to have significantly better results on weight loss in relation to that in fundus [F], but many balloons initially placed in the F were eventually found in the A. The aim of the present analysis was to evaluate whether the balloon position [firmly in F, firmly in A, or transient from F to A [FA]] influences the 3- and 6-month weight loss. MATERIAL Six hundred sixty-eight patients that underwent successful BIB treatment were assigned into three groups: group F [n = 354], group A [n = 159], and group AF [n = 155]. Weight loss parameters were recorded and analyzed at 3 and 6 months. RESULTS In all three groups, there was a significant, progressive reduction of BMI at 3 and 6 months. At 6 months, BMI reduction between groups F and A, and F and FA [p = 0.001] and groups A and FA [p = 0.018] was prominent. CONCLUSION The position of the BIB affects its effectiveness: better results when antrum is involved. This observation seems to give a great perspective to newly established gastric space-occupying devices, which aim to have a compartment constantly present in the antrum. However, further studies have to be performed in order to validate the results and more importantly to clarify the mechanisms implied.

Endosc Int Open 2019; 7:E122-E129. [PMID: 30705942 PMCID: PMC6342679 DOI: 10.1055/a-0809-4994] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 10/26/2018] [Indexed: 12/16/2022] [Imported: 08/29/2023] Open
Abstract
Background and aim Intragastric balloon placement is established as a safe, relatively low-cost and well-tolerated minimally invasive procedure for weight loss, giving encouraging results under the strict prerequisite that the obese patient will enroll in a medically supervised weight loss program. This retrospective study reviews already published cases of severe visceral complications for the purpose of assigning responsibility to the device, the patient, or the doctor. Methods We reviewed PubMed and Scopus archived publications describing intragastric balloon (BIB/Orbera)-related severe visceral complications, i. e. perforations and obstructions. Results Twenty-two cases of gastric perforation, two cases of esophageal perforation and 10 cases of bowel obstruction were found. For the gastric perforation the endoscopist was responsible in nine cases, the patient in four, and the balloon itself in nine. For the two cases of esophageal perforation, the endoscopists were responsible, while for the 12 cases of bowel obstruction, the patient was responsible for seven and the device for the other five cases. Conclusion BIB/Orbera balloon insertion remains a safe procedure, with a minimum of complications related to hollow viscera. Mandatory education and accreditation of physicians dealing with bariatric endoscopy and strict supervision of the obese individuals, while living with the balloon, will eliminate such complications.

Abstract
Adhesions formation is considered a significant clinical entity implicating the healing process following major abdominal surgery, with serious clinical consequences and need for substantial health care expenditures. Several agents and substances applied either locally or systematically could potentially function as inhibitors of the formation of peritoneal adhesions endowed by limiting tissue apposition during the critical stages of mesothelial repair. Phospholipids are identified as surfactant-like substances, acting as a temporary membrane-like coverage of serosal defects. The experimental use of phospholipids for adhesions formation totals 24 publications. All retrieved studies, out of two, demonstrated the efficacy of phospholipids use in adhesions prevention. A single intraperitoneal dose of approximately 75 mg/kg of phosphatidylcholine, for a 30-min exposure time, emerges as the standard practice in terms of efficacy in both surgical alone or combined to peritonitis settings. The findings revealing an unimpeded healing of anastomoses and laparotomy wounds support the safety of this agent. The two additional properties of intraperitoneal use of phospholipids involve the inhibition of bacterial adherence/growth following impregnation of intra-abdominal drainages with phospholipids, without influencing bacterial translocation and the elimination of peritoneal carcinosis, through inhibition of intraperitoneal adhesion of tumor cells. The latter effect is achieved by a dose of phospholipids equal to 150 mg/kg. These experimental data, support that the intraperitoneal phospholipids administration can forestall adhesions formation following intra-abdominal surgical trauma, with no considerable overdosing-related adverse effects. Furthermore, these substances could possibly attenuate posttraumatic inflammation, and inhibit intraperitoneal tumor cell adhesion.

Percutaneous endoscopic gastrostomy feeding of locally advanced oro-pharygo-laryngeal cancer patients: Blenderized or commercial food? Oral Oncol 2017; 74:135-141.

Abstract
OBJECTIVES Head and neck cancer patients commonly suffer from severe malnutrition at the time of tentative diagnosis. Percutaneous Endoscopic Gastrostomy [PEG] feeding is now considered as an efficient tool to reduce nutritional deterioration alongside concurrent treatment. We undertook the challenge to retrospectively evaluate the impact of a commercial, disease-specific, feeding formula [Supportan, Fresenius Kabi, Hellas] versus blenderized family food on nutritional outcome. MATERIALS AND METHODS This is a retrospective analysis of prospectively collected nutritional and anthropometric data at the time of PEG placement, at the 8th week [after treatment termination] and at 8 months [6mo of recovery from treatment]. All patients were prescribed a commercial feeding formula. RESULTS The final dataset included 212 patients: 112 received the commercial formula, 69 voluntarily decided to switch into blenderized-tube-feeding, and 31 were prescribed to receive a home-made formula of standard ingredients. The commercial formula seemed to help patients to fight the catabolism of concurrent treatment, since, at the 8mo assessment, both Body Mass index and Fat Free Mass had almost recovered to the values at the time of first diagnosis. Neither group on blenderized or home-made formulas exhibited nutritional improvement, but experienced a significant deterioration throughout the study period, with the home-made formula group being the worst. CONCLUSION These findings clearly indicate that home-made and blenderized foods do not adequately support the nutritional requirements of patients with HNC scheduled to receive concurrent CRT treatment.

Abstract
The trigger for infectious complications in patients following major abdominal operations is classically attributed to endogenous enteral bacterial translocation, due to the critical condition of the gut. Today, extensive gut microbiome analysis has enabled us to understand that almost all "evidence-based" surgical or medical intervention (antibiotics, bowel preparation, opioids, deprivation of nutrition), in addition to stress-released hormones, could affect the relative abundance and diversity of the enteral microbiome, allowing harmful bacteria to proliferate in the place of depressed beneficial species. Furthermore, these bacteria, after tight sensing of host stress and its consequent humoral alterations, can and do switch their virulence accordingly, towards invasion of the host. Probiotics are the exogenously given, beneficial clusters of live bacteria that, upon digestion, seem to succeed in partially restoring the distorted microbial diversity, thus reducing the infectious complications occurring in surgical and critically ill patients. This review presents the latest data on the interrelationship between the gut microbiome and the occurrence of complications after colon surgery, and the efficacy of probiotics as therapeutic instruments for changing the bacterial imbalance.

Abstract
We present the case of a woman on whom a percutaneous endoscopic gastrostomy (PEG) was performed through the sinus tract of a previous surgical gastrostomy for supraglottic obstructing malignancy. Five years after the induction of the surgical gastrostomy, she experienced a peristomal leakage, leading to severe necrotizing fasciitis, with skin irritation and inflammation. Despite extensive treatment to heal the abdominal wall close to the feeding tube, it recurred 3 months later, without any obvious cause. It was thus decided to perform a new gastrostomy in a nearby normal skin area, but, since it was totally impossible for the endoscope to be passed by mouth, due to obstruction, the sinus tract of the gastrostomy was used to facilitate endoscope insertion into the stomach for a new PEG.

Abstract
OBJECTIVE We aimed to ascertain the factors potentially contributing to the manifestation of pressure ulcers (PU) due to poor nutritional status in a nonselected hospitalized population. SUBJECTS AND METHODS This is a prospective cohort study of 471 adult inpatients treated at our university hospital. Study parameters included anthropometric data, demographics, medical history, mood status, diet-related factors and self-perception of health status. For each participant, the body mass index (BMI) was calculated, and a malnutrition universal screening tool (MUST) was used to screen for nutritional deficiencies, with the presence of PU constituting the outcome of interest. An independent-samples t test, χ(2) analysis and logistic regression analysis were performed. RESULTS The overall prevalence of PU in our cohort was 14.2%. Advanced age, low BMI, poor health status by self-assessment, serious mood disorders, malnutrition, abnormal appetite status, a quantity of food intake half of normal, an artificial diet, limited or no autonomy in everyday activities (p < 0.01 for all) and recent weight loss (p < 0.05) were identified as important determinants for the manifestation of PU. Multivariate analysis highlighted limited autonomy in everyday activities (OR 6.456 and 95% CI 3.212-12.973; p = 0.000), MUST score (OR 3.825 and 95% CI 1.730-8.455; p = 0.001) and artificial diet (OR 1.869 and 95% CI 1.247-2.802; p = 0.018) as the most powerful predictors of PU development. CONCLUSION Poor nutritional status, limited autonomy in everyday activities and artificial nutrition seemed to confer noteworthy prognostic value regarding PU development in the acute-care setting.
