A big data analysis of COVID-19 impacts on Airbnbs' bookings behavior applying construal level and signaling theories.

This study investigates the impact of the COVID-19 pandemic on consumer booking behavior in the peer-to-peer accommodation sector. This study used a dataset composed of 2041,966 raws containing 69,727 properties located in all 21 Italian regions in the pre- and post-COVID-19. Results show that in the pre-COVID-19 period, consumers preferred P2P accommodations with price premiums and located in rural (versus urban) areas.

The pricing of European airbnb listings during the pandemic: A difference-in-differences approach employing COVID-19 response strategies as a continuous treatment.

The COVID-19 pandemic has been a major shock to the global tourism industry. Given its peculiarity, this paper analyzes one of the most intriguing questions in the Airbnb literature - the pricing of Airbnb listings - by taking advantage of a difference-in-differences methodology that largely draws on variations in country-level policy responses to the pandemic. Relying on a dataset containing weekly information from 130,999 continuously active listings across 27 European countries from 2019 to 2020, this study first investigates the exogenous impact of response policies (proxied by the COVID-19 Stringency Index) on demand.

Relaparoscopy in the management of post-operative complications after minimally invasive gastrectomy for gastric cancer.

Laparoscopy has already been validated for treatment of early gastric cancer. Despite that, no data have been published about the possibility of a minimally invasive approach to surgical complications after primary laparoscopic surgery. In this multicentre study, we describe our experience in the management of complications following laparoscopic gastrectomy for gastric cancer.

Interstitial lung abnormalities: new insights between theory and clinical practice.

Interstitial lung abnormalities (ILAs) represent radiologic abnormalities incidentally detected on chest computed tomography (CT) examination, potentially related to interstitial lung diseases (ILD). Numerous studies have demonstrated that ILAs are associated with increased risk of progression toward pulmonary fibrosis and mortality. Some radiological patterns have been proven to be at a higher risk of progression.

Imaging in non-cystic fibrosis bronchiectasis and current limitations.

Non-cystic fibrosis bronchiectasis represents a heterogenous spectrum of disorders characterised by an abnormal and permanent dilatation of the bronchial tree associated with respiratory symptoms. To date, diagnosis relies on computed tomography (CT) evidence of dilated airways. Nevertheless, definite radiological criteria and standardised CT protocols are still to be defined.

[Phosphorus binders: trigger for intestinal diverticula formation in an ADPKD patient].

Hyperphosphoremia is common in patients with chronic kidney disease and is an important risk factor in this patient population. Phosphate binding drugs are a key therapeutic strategy to reduce phosphoremia levels, although they have significant side effects especially in the gastrointestinal tract, such as gastritis, diarrhoea and constipation. We report the case of a haemodialysis-dependent patient suffering from chronic kidney disease stage V KDIGO secondary to polycystic autosomal dominant disease; treated with phosphate binders, the case was complicated by the appearance of diverticulosis, evolved into acute diverticulitis.

Barbed suture in gastro-intestinal surgery: A review with a meta-analysis.

Background: The laparoscopic approach is a very popular technique for many gastrointestinal operations and barbed sutures may improve the difficulties of intracorporeal anastomosis by eliminating the need for knot tying. The aim of this systematic review with a meta-analysis is to explore literature to establish the security profile of barbed suture compared with conventional laparoscopic sutures.

Materials And Methods: A systematic search was performed in all electronic databases (PubMed, Web of Science, Scopus, EMBASE) and 12 studies were included in the analysis, involving 27,133 patients, whereof 3372 cases (patients undergone barbed suture usage) and 23,761 controls (patients undergone conventional suture usage).

Frequency and characterization of ancillary chest CT findings in COVID-19 pneumonia.

Objectives: Ground-glass opacity and consolidation are recognized typical features of Coronavirus disease-19 (COVID-19) pneumonia on Chest CT, yet ancillary findings have not been fully described. We aimed to describe ancillary findings of COVID-19 pneumonia on CT, to define their prevalence, and investigate their association with clinical data.

Methods: We retrospectively reviewed our CT chest cases with coupled reverse transcriptase polymerase chain reaction (rt-PCR).

The role of the radiologist in diagnosing the COVID-19 infection. Parma experiences.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new virus responsible for the coronavirus disease 2019 (COVID-19), a respiratory disease that ranges from an asymptomatic or mild flu-like illness to severe pneumonia, multiorgan failure, and death. Imaging might play an important role in clinical decision making by supporting rapid triage of patients with suspected COVID-19 and assessing supervening complications, such as super-added bacterial infection and thrombosis. Further studies will clarify the real impact of imaging on COVID-19 patients' management and the potential role of radiology in future outbreaks.

Incidence and risk factors of portomesenteric venous thrombosis after colorectal surgery for cancer in the elderly population.

Background: Although it is known that portomesenteric venous thrombosis (PMVT) is associated with total colectomy and proctocolectomy in young patients with inflammatory bowel disease, little is known about incidence and risk factors of PMVT among the elderly population undergoing colorectal surgery for cancer.

Methods: Data of elderly patients (> 70 years) undergoing surgery for colorectal cancer were retrospectively registered. The occurrence of PMVT was correlated with the patients' characteristics and operative variables.

Minimally Invasive Pilonidal Sinus Treatment: A Narrative Review.

The management of chronic pilonidal disease remains controversial, but recently, new minimal invasive approaches have been proposed. Whereas in the conventional surgical treatment an elliptical wedge of skin and subcutaneous tissue is created to remove the sinus and its lateral tracks, the basis for our new treatment is to create a minimal elliptical wedge of the subcutaneous tissue, including all the inflamed tissue and debris while leaving the overlying skin intact. The mechanism of an endoscopic approach relies on use of the endoscope without cutaneous tissue damage.

Barbed Suture and Gastrointestinal Surgery. A Retrospective Analysis.

Although minimally invasive surgery is recognized as the gold standard of many surgical procedures, laparoscopic suturing is still considered as the most difficult skill in laparoscopic surgery. The introduction of barbed sutures facilitates laparoscopic suturing because it is not necessary to tie a knot. The efficacy of this method has been evaluated in different types of surgery; however, less is known about general surgery.

Patient navigators: Mapping the route toward accessibility in health care.

Children and youth with developmental and mental health conditions require a wide range of clinical supports and social services to improve their quality of life. However, few children and youth are currently able to adequately access these clinical, community and social services, and newcomers or those living in poverty are even further disadvantaged. Patient navigator programs can bridge this gap by facilitating connections to social services, supporting family coping strategies and advocating for patient clinical services.

Intracorporeal versus extracorporeal anastomosis after laparoscopic gastrectomy for gastric cancer. A systematic review with meta-analysis.

Aim: To perform a systematic review and meta-analyses of studies comparing the totally laparoscopic procedures with intracorporeal anastomosis (IA) to laparoscopic-assisted surgery with extracorporeal anastomosis (EA) in gastric resections.

Methods: We performed a systematic search in the electronic databases. Outcomes analysed were: intraoperative (operative time and intraoperative blood loss), oncologic (harvested nodes, distance of the tumour from proximal and distal margin), postoperative complications (gastric stasis, intraluminal and extraluminal bleeding, leakage and wound infection) recovery (time to first flatus, time to first oral intake and hospital stay).

Comparison between LigaSure™ and Harmonic® in Laparoscopic Sleeve Gastrectomy: A Single-Center Experience on 422 Patients.

Background: New laparoscopic devices, such as electrothermal bipolar-activated devices (LigaSure™ (LS)) or ultrasonic systems (Harmonic® scalpel (HS)), have been applied recently to bariatric surgery allowing to reduce blood loss and surgical risks. The aim of this study was to retrospectively compare intraoperative performance of HS and LS, postoperative results, and clinical outcomes in a large cohort of patients undergoing LSG.

Methods: Data from 422 morbidly obese patients undergoing LSG in our Bariatric Unit at the Advanced Biomedical Sciences Department of the "Federico II" University of Naples (Italy) between January 2009 and December 2017 were retrospectively analyzed.

Video-assisted ablation of pilonidal sinus (VAAPS) versus sinusectomy for treatment of chronic pilonidal sinus disease: a comparative study.

Since its first description in 1883, different treatments for pilonidal sinus disease have been proposed, but we are still far from the identification of an ideal approach. The objective of this study is to determine if video-assisted ablation of pilonidal sinus (VAAPS) could be considered superior/non-inferior to standard sinusectomy for treatment of pilonidal sinus disease. After applying propensity score analysis, data from 40 patients who underwent sinusectomy and 40 patients who underwent VAAPS, from March 2011 to August 2013, were collected.

Surgical resection for rectal cancer. Is laparoscopic surgery as successful as open approach? A systematic review with meta-analysis.

Background: Recently, it has been questioned if minimally invasive surgery for rectal cancer was surgically successful. We decided to perform a meta-analysis to determine if minimally invasive surgery is adequate to obtain a complete resection for curable rectal cancer.

Methods: A systematic search pertaining to evaluation between laparoscopic and open rectal resection for rectal cancer was performed until 30th November 2016 in the electronic databases (PubMed, Web of Science, Scopus, EMBASE), using the following search terms in all possible combinations: rectal cancer, laparoscopy, minimally invasive and open surgery.
