Most hospitalized COVID-19 pneumonia patients are older adults and/or have nutrition-related issues. Many are bedridden in intensive care units (ICU), a well-documented cause of malnutrition, muscle wasting, and functional impairment. Objectives: To assess the effectiveness of an intensive rehabilitation program over the nutritional/functional stat...

Introduction: Anastomotic leak (AL) is a dangerous complication in the early postoperative period after total gastrectomy or esophagectomy being associated with high mortality. Self-expandable metal stents (SEMS) play a significant role in AL management. Only one case report described the use of Mega-Stent in AL setting. The authors report a two-ca...

The authors aimed to assess the impact of HPN/HPH on nutritional status and survival of long-term IF patients, as well as HPN/HPH-related complications. Methods: This was a retr...
Ageism refers to stereotyping (how we think), prejudice (how we feel), and discrimination (how we act) against people based on their age. It is a serious public health issue that can negatively impact older people’s health and quality of life. The present protocol has several goals: (1) adapt the Ambivalent Ageism Scale for the general Portuguese p...

Upper gastrointestinal bleeding (UGIB) is a common cause of hospital admission and variceal hemorrhage is responsible for many UGIB cases. Esophageal and gastric varices are caused by portal hypertension (PHT), mostly due to liver cirrhosis. Portal vein thrombosis (PVT) is an important cause of non-cirrhotic PHT and can be associated with several d...
Intestinal failure is the reduction in gut function below the minimum necessary for the absorption of macronutrients and/or water electrolytes. The based treatment for type II and III intestinal failure patients is home parenteral nutrition (HPN) and hydration (HPH). This is a case-series study of HPN/HPH patients of the Hospital Garcia de Orta, Po...
The hallmark of Parkinson’s disease (PD) is the accumulation of alpha-synuclein (AS) aggregates. Prior to the central nervous system involvement, PD establishes itself in the gut as a result of the complex interplay between microbiota, the host’s immune/neural systems and increased intestinal permeability. Inflammatory Bowel Disease (IBD) patients...
A growing body of evidence suggests that nutritional status may play an important role in the development and course of Parkinson’s disease (PD). Nutritional status is known to influence PD motor and non-motor features and is in turn influenced by disease duration and severity. A proper nutritional status assessment and intervention should be incor...
The neuropathological hallmark of Parkinson’s disease (PD) is the accumulation of alpha–synuclein (AS) aggregates. The identification of AS aggregates in gut biopsy specimens from people with PD may provide an opportunity to identify PD at a very early stage, prior to symptom onset. Changes in gut microbiota and inflammatory conditions (such as per...
Nutrition status is a major issue of the COVID-19 pandemic. Many factors associated with worse prognosis risk are related to nutrition. Patients received after hospital discharge for pneumonia due to SARS-Cov-2 were submitted to a multidisciplinary rehabilitation program. This study aimed to analyze the nutritional and functional status after SARS-...

Introduction:
Dieulafoy's lesion (DL) is a rare but important cause of acute, severe, life-threatening, and recurrent upper gastrointestinal bleeding (UGIB). It is frequently difficult to diagnose DL with upper GI endoscopy (UGIE), and endoscopic ultrasonography (EUS) may be valuable. There are only 2 reported bleeding cases caused by two synchron...

Percutaneous endoscopic gastrostomy (PEG) is a safe technique for long-term enteral feeding. The most common PEG-associated adverse events are minor. Gastrocolocutaneous fistula (GCCF) results from misplacement of the PEG tube through the colon. The importance of this complication is not currently defined, and there is no clearly established therap...
Introduction: Endoscopic gastrostomy (PEG) is the gold standard for long-term enteral feeding for patients who lose the ability to swallow, which deprives the passage of food and liquids through the mouth. Normal oral microbiota is known to perform functions of protection and maintenance of oral and systemic health. Therefore, oral dysbiosis, promo...
