Magnetic Sphincter Augmentation for Gastroesophageal Reflux After Sleeve Gastrectomy: A Systematic Review.

This systematic review aims to evaluate the current evidence regarding safety and efficacy of magnetic sphincter augmentation (MSA) for the treatment of gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG). Conversion to Roux-en-Y gastric bypass (RYGB) carries the risk of surgical and metabolic complications and may be contraindicated in patients with normalized or near-normalized body mass index. The LINX™ procedure aims to restore LES competency and to repair the crura.

Clinical Use of Paraprobiotics for Pregnant Women with Periodontitis: Randomized Clinical Trial.

Periodontal disease is very common in pregnant women. Paraprobiotics are a subset of probiotics. They can be defined as inactivated microbial cells providing health benefits to the host and are considered particularly safe.

Periodontitis in Pregnant Women: A Possible Link to Adverse Pregnancy Outcomes.

Background: Periodontitis develops in 11% of pregnant women, and it is independently linked to severe complications during pregnancy such as preterm birth, low birth weight, and gestational diabetes.

Methods: A literature search (Pubmed/MEDLINE, and Scopus) from 2003 to 2023 was conducted to analyze studies focused on periodontitis and adverse pregnancy outcomes.

Results: 16 articles have been included.

Developmental Strategy and Validation of the Midwifery Interventions Classification (MIC): A Delphi Study Protocol and Results from the Developmental Phase.

This study protocol aims to describe the rationale and developmental strategy of the first study in the Italian context which aimed to define a Midwifery Interventions Classification, an evidence-based, standardized taxonomy and classification of midwifery interventions. Midwifery interventions require a specific definition, developed through a consensus-building process by stakeholders to develop the Italian taxonomy of the Midwifery Interventions Classification with the potential for international transferability, implementation, and scaling up. A multi-round Delphi study was designed between June and September 2022, and data collection is planned between February 2023 and February 2024.

Patient-tailored algorithm for laparoscopic cruroplasty standardization: comparison with hiatal surface area and medium-term outcomes.

Background: Different methods have been described for laparoscopic hiatoplasty and hiatus hernia (HH) repair. All techniques are not standardized and the choice to reinforce or not the hiatus with a mesh is left to the operating surgeon's preference. Hiatal surface area (HSA) has been described as an attempt at standardization; in case the area is > 4 cm, a mesh is used to reinforce the repair.

Laparoscopic management of pathologic gastroesophageal reflux after sleeve gastrectomy using the magnetic sphincter augmentation (MSA) device-a Video Vignette.

Purpose: The development of gastroesophageal reflux disease (GERD) has been shown to be not infrequent after laparoscopic sleeve gastrectomy (LSG). Management may vary from medical therapy to Roux-en-Y gastric bypass (RYGB) conversion. Magnetic sphincter augmentation (MSA) device has been shown to be a promising option with excellent results.

Surgical treatment of recalcitrant gastroesophageal reflux disease in patients with systemic sclerosis: a systematic review.

Introduction: Gastroesophageal reflux disease (GERD) is frequently seen in patients with systemic sclerosis (SSc). Long-standing GERD may cause esophagitis, long-segment strictures, and Barrett's esophagus and may worsen pre-existing pulmonary fibrosis with an increased risk of end-stage lung disease. Surgical treatment of recalcitrant GERD remains controversial.

Effect of Body Position on High-resolution Esophageal Manometry Variables and Final Manometric Diagnosis.

Background/aims: According to the Chicago classification version 3.0, high-resolution manometry (HRM) should be performed in the supine position. However, with the patient in the upright/sitting position, the test could more closely simulate real-life behavior and may be better tolerated.

The Malnutrition Universal Screening Tool can predict malnutrition in patients with esophageal achalasia.

Background: At present, little research has been done to clarify why some achalasia patients do not lose weight or are even obese and to investigate their nutritional status. The aim of this study was to identify predictive factors of malnutrition in these patients and to assess their response to treatment.

Methods: We conducted a retrospective cohort study on consecutive patients referred to a tertiary-care center for laparoscopic or endoscopic treatment of achalasia.

Fecal Clostridiales distribution and short-chain fatty acids reflect bowel habits in irritable bowel syndrome.

Irritable bowel syndrome (IBS), a common functional gastrointestinal disorder, is classified according to bowel habits as IBS with constipation (IBS-C), with diarrhea (IBS-D), with alternating constipation and diarrhea (IBS-M), and unsubtyped (IBS-U). The mechanisms leading to the different IBS forms are mostly unknown. This study aims to evaluate whether specific fecal bacterial taxa and/or short-chain fatty acids (SCFAs) can be used to distinguish IBS subtypes and are relevant for explaining the clinical differences between IBS subcategories.

Detection of small bowel tumors by videocapsule endoscopy in patients with acromegaly.

The prevalence of colon polyposis andmalignancies is increased in acromegalic patients as compared to the general population. An epidemiological study suggests a high prevalence also of small bowel (SB) tumors that nowadays may be detected by videocapsule endoscopy (VCE). The aim of the study was to assess the prevalence of SB neoplasms using VCE in acromegalic patients in comparison to control subjects and to correlate it with cancer risk factors and acromegaly-related parameters.

Perceptual sensitivity and response bias during rectal distension in patients with irritable bowel syndrome.

Patients with irritable bowel syndrome (IBS) report an increased frequency of sensations during rectal distension in comparison with healthy subjects. This alteration might be due to a psychological response bias leading patients to over report their sensations. The aim of this study was to measure perceptual sensitivity and response bias during rectal distension in healthy subjects and IBS patients using the sensory decision theory (SDT).

Effect of rectal distension on abdominal girth.

It has been postulated that a viscerosomatic reflex activated by gut distension and inhibiting abdominal wall muscle tone may be one of the mechanisms underlying functional abdominal distension. Any demonstration of such a reflex has to take into account the fact that gut distension may increase abdominal girth as a result of volume displacement. As biomechanical and sensory rectal responses vary at different rates of rectal distension, we hypothesized that different rates of rectal distension might reveal different changes in abdominal girth.

Abdominal distension after colonic lactulose fermentation recorded by a new extensometer.

Colonic lactulose fermentation induces bloating, but whether it also causes abdominal distension is not known. The aim of this study was to assess the effect of colonic lactulose fermentation on abdominal girth using a new extensometer. We recorded abdominal girth in 24 healthy subjects by means of an extensometer that measures the phase shift of an ultrasound wave propagating in a tube encircling the abdomen.

Influence of caloric intake on gastric emptying of solids assessed by 13C-octanoic acid breath test.

Background: The 13C-octanoic breath test (13C-OBT), a recently developed technique to evaluate gastric emptying of solids, has been validated in comparison to scintigraphy with low caloric meals (250 kcal). However, there is consensus that for clinical studies total caloric load should be in excess of 300 kcal, but studies comparing 13C-OBT results after low and medium caloric meals are lacking.

Methods: Ten healthy subjects were given a 250-kcal and a 550-kcal meal in randomized order.

HCV genotypes in Northern Italy: a survey of 1368 histologically proven chronic hepatitis C patients.

Background/aims: Hepatitis C virus (HCV) easily undergoes genomic changes, thus accounting for the presence of different genotypes, with different geographic distributions and different outcomes of chronic hepatitis. Type 1b is frequently found in advanced diseases; however, since this genotype is the most prevalent in older patients, the association with advanced age and severity of the disease is confounding. The aim of this study was to assess changes in the prevalence of HCV genotypes by surveying a large population of chronic hepatitis C patients in Northern Italy, and to assess if the high prevalence of genotype 1b in older patients with advanced diseases simply reflects the duration of HCV infection, rather than intrinsic biological properties of HCV.
